Patients benefit from genetic counseling to understand the risks of transmission to their children. Patients should be instructed to reduce the stress in their lives and to remain hydrated. Depression, sleep disturbances, and nicotine addiction are important issues to address. There are reports of successful transplants but multiple complications have also been described. It may be difficult to get an appropriate match as fewer than 20% of patients have been shown to have a matched sibling donor. There are reports offailed engraftment and graft versus host disease following transplantation. There was initial enthusiasm that umbilical cord blood may be an additional source of transplantation. However, even umbilical cord blood has met with the same type of complications described above: a high rate of engraftment failure and reports of graft versus host disease. Lentiviruses have been used as a vector to introduce stem cells transduced with an antisickling ~ globin variant capable of marrow engraftment and subsequent production of normal white blood cells, platelets, and increased HbA levels. However, these trials are just beginning and not available outside research protocols. With the exception of the need for fetal surveillance, the care of a pregnant patient with a vasoocclusive crisis does not differ substantially from the care given to a nonpregnant patient. Prophylactic transfusions have reduced the number and severity of these episodes in some but not all studies and are accompanied by the risks of alloimmunization, fluid and iron overload, transfusion reactions, and immune suppression. During pregnancy, prenatal visits should be scheduled frequently and care coordinated between obstetricians, maternal fetal medicine, and hematology ideally at centers with interest and expertise. Prophylactic transfusion for pregnant women with sickle cell disease: A systematic review and meta-analysis. The intricacies ofa cesarean hysterectomy often extend beyond the scope ofa general gynecology. Recent research has started to show improved outcomes for patients with abnonnally invasive placentation using a multidisciplinary approach and in specialized centers. Commonly observed outcomes with a cesarean hysterectomy include increased blood loss, intraoperative injury. Every placenta accreta presents a unique challenge; therefore a well-studied and organized team will offer the greatest chance for a successful outcome. Placenta accreta is a potentially life threatening condition that continues to challenge the medical field. The prevalence has been on a steady rise over the last few decades, currently between 1 in 533 to l in 731 of all deliveries,1 becoming a commonality in obstetrics. Placenta accreta is defined by an abnormal attachment between the placenta and the myometrium of the uterus. The extent of invasiveness is categorized into three different categories: acc::reta, increta, and percreta. Chorionic villous attachment beyond the normal boundary of Nitabuch layer with superficial attachment ofthe m:yometrium is an accreta, villous invasion into the myometriwn is increta, and villous invasion up to and beyond the uterine serosa is a percreta. Most morbidities present during the delivery stage and include complications such as uterine atony or postpartum hemorrhage, which can lead to disseminated intravascular coagulopathy, renal failure, or require hysterectomy. Mortality rates increase directly with the degree of invasion and can reach a level as high as 7%.

Historically, factors such as multiparity, age, substance abuse, and reproductive technology have been associated with placenta accreta but the exact reasons for these risk factors and their contributions are still under investigation. The evaluation often begins during the second trimester, and some studies have evaluated early first trimester findings. Evidence of low implantation or cesarean scar ectopic is predictive of abnormally invasive placentation. Other diagnostic signs start to present around the 15th week of gestation, although when used prior to 15 weeks have a lower sensitivity. The earliest and most predictive findings are lacunae, or vascular lakes, with a sensitivity of 79% and positive predictive value of 93%. Loss of the hypoechoic zone is a well-known and commonly used marker for diagnosing an accreta, and has a sensitivity of 57% at less than 20 weeks gestational age, and only 80% at 20weeks. Color Doppler can be used with ultrasound to assess vascular flow in the placenta. As an independent modality, color Doppler does not add great diagnostic benefit but it can be helpful when looking at the serosa-bladder wall. Increased vascularization along both the uterine serosabladder wall and perpendicular to the uterine wall has the highest positive predictive value of 92%. Each ultrasound finding carries its own advantage in diagnostics, and the presence of more than one marker increases the overall predictive value. In addition to imaging, there is a relationship between maternal serum markers and abnormal placentation. Early diagnosis, planning, and preparation are keys to successful surgery and reducing blood loss at time of delivery. Centers with appropriate experience, such as a Center of Excellence, often times use a multidisciplinary team approach, track outcomes, and perform continuous quality improvement to optimize results. Early referral to centers specializing in the management of patients with an abnormally invasive placenta should take place as soon as suspected so that patients may have early access to consultants, diagnostic imaging, and counseling regarding treatment options. The risk of maternal and fetal mortality may be as high as 7% and 9% for maternal and fetal mortality, respectively. Early referral may allow patients to determine their options for termination of pregnancy, delivery timing, delivery methods, and future child bearing needs. At this time definitive surgical management is recommended, although uterine preserving or conservative management may be used in select patients. The risk of spontaneous bleeding or labor increases after 30 weeks gestation, and patients should be counseled on those risks. Ideal timing for delivery is recommended at 34 weeks7 based on a decision tree analysis comparing delivery strategies from 34 to 39 weeks in patients with an accreta and a previa, with or without amniocentesis. The findings suggest better outcomes with an early delivery preferably at 34 weeks, and showed no utility in determining lung maturity via amniocentesis. Patients without a previa may reasonably be delivered at 37 weeks gestational age. There may be limited situations in which a delivery may be considered after 37 weeks, such as patients where the diagnosis is in doubt and no prior uterine surgeries or previa. Delivery prior to labor or active bleeding may have shorter operative times, blood loss, and length of stay. The ultimate decision should take into consideration the individual patient and their desires, confounding risk factors, fetal well being, provider comfort, and availability of hospital resources. Delivery options are an important discussion that must include the patient, delivery provider, and other disciplines. A cesarean hysterectomy is the definitive treatment for abnormally invasive placentation, and may be the most effective method. Alternatives to a planned cesarean hysterectomy, such as conservative management or a delayed hysterectomy, are considered experimental and should not be the default method of management. If these options are pursued, it is recommended to be with a center that has experience or expertise for managing and monitoring the complications associated with alternative treatment. Candidates for conservative management and delayed hysterectomy must be carefully chosen and may include those with a fundal placenta, a small localized accreta, or a posterior accreta. Patients must be counseled extensively on the risks, and will require a prolonged period of observation until resolution. Prior to beginning any surgical intervention, the level of anesthesia needs to be discussed. There are no known advantages for general anesthesia, regional anesthesia, or a combination ofboth with abnormally invasive placentation. The use of a combined spinal/epidural is not unreasonable based on delivery planning and expectations. The patient should always be consented for both types of anesthesia and informed that transition from regional to general during the procedure is a possibility. Prior to beginning the procedure, the patient should have a current (within 72 hours) type and screen and baseline hemoglobin and hematocrit in anticipation for the need for blood products.

There is a well-demarcated area along the serosal surface that corresponds to abnormally Invasive placentatlon. Surgical Approach A staged surgical approach is often used with multidisciplinary approaches. The first step may include evaluating the urinary tract and placing ureteral stents. A vertical midtine incision offers better visualization and access in preparation fur complications and may be the preferred entry to facilitate uterine entry or control of vascular pedicles. Intraoperative ultrasound fur placental mapping can confirm preoperative findings suspicious fur invasive placentation, and to identify the limits of the placenta. Exteriorization-Abdominal incision is extended until access to an area without underlying placenta is accessed. Exterlorlzatlon Inspection-Placenta Percreta with extension laterally Into the broad ligament. Hysterotomy incision-Uterine incision placed superior to placental edge prior to manual blunt extension. Transfundal incision-uterine incision placed at the superior edge of fundus and extended posteriorly with manual blunt extension. Some centers also employ use ofa uterine stapler to make the incision which may decrease blood loss. The fetus is delivered without manipulation of the placenta to avoid partial placental separation. Multiple studies have assessed the most effective method ofcontrolling blood loss from the uterine vessels. A disadvantage of preoperative placement is exposure of the fetus to ionizing radiation. Postcesarean embolization has demonstrated an 8996 to 91% success rate at decreasing overall blood loss and is technically achievable in up to 97% of accreta patients. Gynecologic oncologists or experienced pelvic surgeons offer great value to this portion of the treatment team. The overall approach to the peripartum hysterectomy is similar to the nonobstetrical approach except there are additional risk factors. The pregnant uterus has 10 to 30 times more blood flow than the nongravid uterus which increases the chance for significant blood loss. In women who report a penicillin allergy, the incidence ofa cephalosporin reaction is slightly increased. Clinically relevant cross reactivity between penicillins and cephalosporins is small. It is reasonable to consider a single clamp and ligation of pedicles as vessel sealing devices have limits to the size of the vessel for which they are approved. The broad ligament is then opened superiorly toward the cornua until an avascular window is identified. The posterior leaf of the broad ligament may be further divided with caution in evaluating for venous varicosity between the uterus and pelvic sidewall.

Comparison between clinical significance of height-adjusted and weight-adjusted appendicular skeletal muscle mass. Age-related declines in muscle mass occur due to reduced number and size of muscle fibers through processes of denervation, apoptosis, and atrophy [2]. In 1988, Irwin Rosenberg proposed the descriptor "sarcopenia" from the Greek sarx for "flesh" and penia for "loss" [3], but since then definitions of sarcopenia have evolved to also include poor muscle function [4,5]. Nevertheless, research has demonstrated that low muscle mass alone is associated with a range of health disorders including insulin resistance [6], cardiovascular disease [7], osteoporosis and fractures [8,9], as well as increased mortality [10]. Thus, strategies which can contribute to the maintenance of skeletal muscle during aging are likely to improve quality of life and longevity in the older adult population. The plasticity of skeletal muscle to hypertrophic stimuli diminishes with age, but there are still opportunities to implement strategies to maintain muscle mass [11]. Lifestyle behaviors represent an attractive target because unlike other contributors to age-related muscle wasting, such as genetic and neuromuscular factors, they are inherently modifiable. Lifestyle modification strategies which can be implemented into public health recommendations can also potentially benefit a large proportion of the older adult population at relatively low costs compared with drug therapy interventions. This article summarizes current literature on associations of lifestyle behaviors and reductions in skeletal muscle mass during aging. A metaanalysis of 49 studies including over 1300 adults aged 50 years and older demonstrated that resistance training interventions result in mean improvements in lean body mass of around 1 kg, and this can be increased with higher volume [13]. Despite this, as few as 5% of adults over the age of 50 years meet guidelines for resistance training [14], suggesting that promotion is important in public health policies. Most observational studies explore associations between general physical activity (including both intentional and incidental movement) and muscle mass in older adults. Early studies utilized self-reported measurements of physical activity which are limited by recall bias but have demonstrated associations for self-reported physical activity, intensity of work activities, and performing exercise during leisure time, with higher muscle mass [16,17], and smaller declines in thigh girth over time [18]. The different instruments used to assess self-reported physical activity are likely to explain conflicting associations with muscle mass in these studies. The advent of devices supporting objective assessments of physical activity has provided new opportunities to expand our understanding of its relationship with muscle mass in older adults. In the Nakanojo Study, a year-long assessment of physical activity using pedometers indicated positive effects of increasing steps/day on appendicular lean mass in older adults with a threshold at approximately 8000 and 6900 steps/day in men and women, respectively [24]. In the Nakanojo Study, older adults who spent,15 minutes/day at or above three accelerometer-determined metabolic equivalents, a level equivalent to moderate intensity physical activity, were more than twice as likely to have low appendicular lean mass relative to height compared with those who spent. While resistance training is likely to confer the greatest muscle mass improvements, minimizing sedentary behavior and increasing movement, particularly at higher intensities, should be a focus of guidelines for maintaining muscle mass during aging. This withdrawal of energy intake can contribute to weight loss which includes declines in skeletal muscle mass, and additional muscle mass and function deficits may occur due to inadequate intakes of specific macronutrients, micronutrients, and vitamins. Recent research has also focused on dietary patterns, which reflect how foods are consumed together, rather than as individual dietary components. Higher dietary variety is associated with greater mean arm muscle area and circumference in frail nursing home residents [29], and Chinese older adults with high scores on a diet quality index focusing on variety, adequacy, moderation, and overall balance of nutrition had half the likelihood of sarcopenia at baseline although not 4 years later [30]. To date, optimal dietary patterns for maintaining muscle mass during aging have not been thoroughly investigated, but future guidelines are likely to be informed by studies of specific nutrients. Adequate dietary protein intake is a key nutritional component for skeletal muscle because protein contains amino acids, including essential amino acids which cannot be synthesized in the body, required for muscle protein synthesis [33]. Due to blunted muscle protein synthesis during aging, older adults may need to exceed current recommendations of 0. Nevertheless, in healthy older adults, there is limited evidence to suggest that protein or amino acid supplementation alone is beneficial for improving muscle mass [39]. Despite the mixed evidence for protein supplementation, longitudinal cohort studies support the beneficial role of higher dietary protein intakes in reducing muscle mass declines during aging. Distribution of protein consumption throughout the day may also influence muscle protein synthesis, with more even distributions across meals associated with higher lean mass in Canadian older adults [44]. Increased levels of inflammatory markers are associated with greater risk of sarcopenia [45]. Omega-3 polyunsaturated fatty acids, primarily found in fish, plants, and nut oils, may enhance muscle mass by reducing inflammation and also by enhancing protein synthesis [2]. An 8-week trial in 16 older adults demonstrated that those randomized to receive omega-3 polyunsaturated fatty acids had increased muscle protein synthesis [47]. Similar effects have also been reported in a recent study of the effects of 16-weeks of omega-3 polyunsaturated fatty acids prior to and after a single bout of resistance exercise. Mixed muscle, mitochondrial, and sarcoplasmic protein synthesis rates increased prior to exercise, and mitochondrial and myofibrillar protein synthesis increased postexercise [48]. Higher intakes of fruits and vegetables have been postulated to protect against muscle mass losses because they are a major dietary source of antioxidants [51,52]. In the Korean National Health and Nutrition Examination Survey, older men in the highest quintile for fruit and vegetable intake had I. Achieving the recommended intake of vegetables in women ($5 servings/day) was also associated with approximately half the likelihood for low muscle mass in the same cohort, although the effect of vegetable intake was not significant in men [54]. Other nutrients associated with higher fruit and vegetable intakes may also contribute to maintenance of muscle mass during aging. Potassium plays a key role in muscle contraction, and dietary and urinary potassium have been positively associated with lean mass and muscle strength in older adults [58,59], although not changes in lean mass over 3 years [40,58]. Dietary magnesium may influence muscle adenosine triphosphate, and also inflammation [60]. Vitamin D, a secosteroid hormone produced in the epidermis following ultraviolet B light exposure and also obtained in smaller amounts from some foods, may have antiinflammatory properties [61]. Vitamin D deficiency is common in older adults due to lifestyle changes and age-dependent decreases in vitamin D metabolism [62]. Vitamin D may also augment mitochondrial oxidative phosphorylation in skeletal muscle [64]. Dietary intakes of vitamin D have also been demonstrated to have no association with muscle mass in a cross-sectional older French women [69,70], although this may reflect the fact that relatively low proportions of total vitamin D are generally obtained from I. Consistent with the concept that vitamin D may benefit muscle function but not muscle mass, a metaanalysis of vitamin D supplementation studies reported a small but significant positive effect on muscle strength relative to placebo or control, but no effect on muscle mass [72]. Vitamin D may therefore exert indirect effects on muscle function that are not explained by muscle mass [73], through improvements in neuromuscular factors such as coordination [74]. A combination of nutritional supplements may be most effective in ensuring adequate dietary intakes and improving muscle mass in older adults. Further clinical trials are required to confirm the optimal combinations of nutrients and dosing regiments, and it is likely that not all older adults, particularly those with adequate diets, demonstrate muscle hypertrophy due to supplementation alone. Nevertheless, combination supplements may be effective at minimizing multiple nutritional deficiencies which contribute to muscle mass declines in older adults over the long term. A recent metaanalysis concluded that, in healthy older adults, protein and amino acid supplementation may only improve muscle mass when combined with exercise [39]. In 155 Japanese women aged 75 years and older randomized to a 3-month exercise program and 3-g day of an amino acid supplement (containing 42. A recent metaanalysis of 49 trials in over 1800 adults not only reported significantly greater increases for fat-free mass and muscle cross-sectional area for resistance training when combined with protein intakes up to approximately 1. Accordingly, some trials have not observed any effect of protein supplementation plus resistance training over resistance training alone for muscle mass in older adults [85,86]. Conversely, in female nursing home residents, 16 weeks of progressive resistance training combined with consumption 160 g of cooked lean red meat consumed 6 days per week resulted in 0. In a 24-week study of frail older adults randomized to a twice-daily 250 mL protein drink (15 g protein) or placebo while completing resistance exercise, lean mass increased by 1. Evidence is also lacking for a synergistic benefit of vitamin D (alone or in combination with protein) supplementation. In a 12-week study, 130 sarcopenic older adults who participated in an exercise program including muscle-building, balance, and gait training, participants were randomized to receive an oral nutritional supplement containing whey protein (22 g), essential amino acids (10. The effects of antioxidant and omega-3 supplements on muscle mass have also been trialed in combination with exercise in older adults. Supplementation consisted of 350 mL of tea fortified with 540 mg of catechin (an antioxidant) each day for 12 weeks. Muscle mass changes did not differ between groups, but only the exercise plus tea catechin group demonstrated significant improvements in leg muscle mass from baseline to follow-up [93]. Fish oil supplements (rich in omega-3) have been shown to enhance improvements in muscle strength and function following a 12-week strength training program in older women [94], but it is unclear whether this relates to effects on muscle mass. This was consistent with a trial of 51 older adults who were randomized to 14 g/day of alpha-linoleic acid (an essential omega-3 polyunsaturated fatty acid) or placebo whilst completing resistance training for 12 weeks. A 62% decrease in interleukin-6 in the omega-3 group was supportive of the antiinflammatory benefits of omega-3 fatty acids, but little effect was seen for muscle thickness (assessed by ultrasound), total lean mass, and muscle strength [96]. It is possible that beneficial effects of omega-3 polyunsaturated fatty acids for muscle hypertrophy in response to exercise may be observed over longer duration interventions; a recent 24-week three-arm trial in which older women were randomized to control, resistance training, or resistance training plus a healthy diet rich in omega-3 polyunsaturated fatty acids reported that whole-body lean mass increased significantly only for the healthy diet group, and this group generally demonstrated greater increases in muscle force than the resistance training alone group [97]. While evidence is lacking for synergistic effects of nutritional supplements and exercise for improving muscle mass in older adults, supplementation may be beneficial for improving exercise benefits, particularly in patients with nutritional deficiencies. For the generally healthy older adult, ensuring adequate intake of important nutrients through the diet may I. By enhancing muscle gains, capacity for subsequent physical activity may also be increased, resulting in even greater exercise benefits in the long term. This metaanalysis is limited by the varying definitions of sarcopenia and alcohol consumption assessments between studies. Furthermore, it is possible that minimal, or even beneficial, effects of moderate alcohol consumption influenced the overall results. Indeed, in postmenopausal women in the Korean National Health and Nutrition Examination Survey, those who reported high-risk alcohol consumption had a fourfold increased likelihood for low muscle mass relative to body weight compared with women who reported low-risk alcohol consumption [102]. Women who reported high-risk drinking in this study were also more likely to be current smokers, but the association of alcohol use and low muscle mass remained significant even after adjustment for potential confounders. Nevertheless, this highlights the fact that unhealthy lifestyle behaviors often aggregate and this is particularly true in individuals with low socioeconomic status. In Australian women, smoking, larger food serving sizes, and low physical activity are most common in individuals from lower socioeconomic groups [104].

Laboratory studies include complete blood count with differential diagnosis and blood chemistries. A urinalysis can be obtained to survey for protein, glucose, blood, casts, and bacteria. Antepartum patients with viable fetuses should undergo continuous electronic fetal heart rate monitoring. Lowering Blood Pressure the drug of choice in hypertensive crisis is sodium nitroprusside. Other drugs such as nitroglycerin, nifedipine, trimethaphan, nicardipine, and hydralazine can also be used. There are risks associated with too rapid or excessive lowering of blood pressure. The aim of the therapy is to reduce the mean arterial pressure by no more than 25%. Small reduction in blood pressure in the first 60 minutes of therapy, working toward a systolic level of 155 to 160 mm Hg and a diastolic level of 100 to 110 mm Hg, is recommended. In chronic hypertensives who have a rightward shift ofthe cerebral autoregulation secondary to medial hypertrophy of the cerebral vasculature, lowering blood pressure too rapidly may result in cerebral ischemia, stroke, or coma. Coronary blood flow, renal perfusion, and uteroplacental blood flow also may deteriorate, resulting in myocardial infarction, acute renal failure, fetal distress, or death. Hypertension that proves increasingly difficult to control is an indication for delivery. Signs of toxicity include anorexia, disorientation, headache, fatigue, restlessness, tinnitus, delirium, hallucinations, nausea, vomiting, and metabolic acidosis. The few published reports regarding nitroprusside use in pregnancy have stated that thiocyanate toxicity rarely occurs if used in standard doses. Whenever toxicity is suspected, however, therapy should be initiated with 3% sodium nitrite at a rate not to exceed S m! It is the drug of choice in preeclampsia associated with pulmonary edema and for control of hypertension associated with tracheal manipulation during intubation and extubation. It is contraindicated in hypertensive encephalopathy because it increases cerebral blood flow and intracranial pressure. Sodium Nitroprusside Sodium nitroprusside causes arterial and venous relaxation by interfering with both the influx and intracellular activation of calcium. The onset of action is immediate and its effect may last 3 to 5 minutes after discontinuation. American College of Obstetricians and Gynecologists; Task Force on Hypertension in Pregnancy.

Despite the widely described negative health consequences of obesity, the obesity epidemic continues to challenge clinicians, researchers, public health policy m. The problem is not solely limited to the devdoped world, as obesity has become a World Health Organimtion focus as it relates to global health improvement initiatives. Globally, more than 1 billion people are overweight with more than 300 million being obese. Cancer, orthopedic complications, diabetes, hypertension, stroke, heart disease, premature death. The unfortunate trend toward a sedentary lifestyle and unhealthful eating habits has likely contributed to this unfortunate and costly situation. Relevant to the practitioner of obstetrics, the prevalence of obesity is higher in women (38.

Colorado remains the "leanest" state, with just 18% of its population obese, while the "heaviest" state is Mississippi, with nearly 35% of its adult population obese. At least nine states have obesity rates of at least 30%, as compared to none in 2000. Clearly, the Healthy People 2010 goals for 15% obesity among adults and 5% in children were not met, and with 2020 nearly upon us, it is unlikely that we will see the Healthy People 2020 goals of an adult obesity rate of 30. Tiris unfortunate "state of the weight" in the United States may ultimately undo the steady gains in overall health we have enjoyed as Americans since the dawn of the 20th century, and now contributes to the deaths of 300,000 Americans annually. The remarkably high prevalence of this condition and its significant negative impact on overall health makes its prevention and treatment a top priority for all healthcare disciplines. Nearly 4% of the overall adult female population is both obese and diabetic, and among diabetic women, 90% are either overweight or obese. This is significant in that obesity in persons with diabetes is associated with poorer control of blood glucose levels, blood pressure, and cholesterol, placing obese individuals with diabetes at higher risk for both cardiovascular and microvascular disease. African-American women have the highest prevalence of obesity (57%), as compared to Hispanic women (46%), and non-Hispanic white women 36%). Tiris is particularly poignant as African-American women incur the greatest numbers of years of life lost to obesityrelated premature mortality. Our patients with limited economic means appear to be disproportionally affected by obesity, given a relatively low prevalence of 29% for those at or 350% above poverty, while those women with income below 130% ofthe poverty level have an increased prevalence to 42%. Additionally; disparity in obesity rates amongst children is noted with the startling finding that one in seven low-income preschool-aged children are now obese. The percentage of overweight children (ages 6-11) has doubled since the early 1980s, while the percentage ofoverweight adolescents has nearly tripled! Fortunately; recent data would indicate a plateauing of obesity prevalence for youth between 2003 and 2014. Obesity negatively impacts virtually all adverse pregnancy outcomes, among which are increased risks for congenital malformations, diabetes, aberrations in fetal growth, stillbirth, hypertensive disorders of pregnancy, labor abnormalities, a higher cesarean section rate, and greater morbidities associated with cesarean delivery. Obesity complicating pregnancy has also been recognized as a significant contributor to an increased use of perinatal healthcare resources, contributing to the ever-increasing costs of healthcare. The complications and challenges posed by obesity in the care of these patients tests even the most "seasoned~ skilled practitioner, especially as it relates to prenatal diagnosis and intrapartum care. Tragically, most dreadful of obstetric complications, maternal death, appears to be on the rise in the 21st century, with obesity now recognized as a likely significant contributor. These patients are indeed high risk and deserving of intense efforts to minimize morbidity and mortality when possible, and thus achieve the best perinatal outcome possible. This article strives to inform the reader of the critical components of obstetric care for the obese gravida, reviewing selected antepartum, intrapartum, and postpartum considerations. Definition Body mass index (kg/m2) Obesity class Underweight Normal overweight Obese Extremely obese <18. The terms overweight and obesity both describe ranges of weight that are greater than what is generally considered healthy for a given height. The terms also identify ranges of weight that have been shown to increase the likelihood ofdisease and other adverse health consequences. Other methods of estimating body fat and body fat distribution include measurements of skinfold thickness and waist circumference, calculation of waist-to-hip circumference ratios, and techniques such as ultrasound, computed tomography, and magnetic resonance imaging. Obesity is most commonly associated with an excess of caloric intake versus expenditure or physical activity, although as noted above, a myriad of factors (psychosocial-economic genetic and environmental) may play roles as well. A small percent may be caused by a diverse group of neurologic and endocrine disorders (Table 6-3). This is somber data, as extreme obesity is associated with the most severe general health and perinatal complications. Given the health implications of obesity, bariatric surgery has become quite common and is among patients of reproductive age not infrequently. Pregnant patients with a history of gastric surgery for obesity should be counseled appropriately and surveillance during prenatal care heightened It is generally recommended to delay childbearing for 12 months post surgery to provide time to optimize weight loss and reduce potential adverse effects of nutritional deficiencies. While some outcomes have been noted as improved with weight loss following bariatric surgery, such as preeclampsia, gestational diabetes, and fetal macrosomia, reports have shown an increased risk for gastric band complications during pregnancy and nutritional deficiencies. Gastrointestinal hemorrhage and other procedure related complications, including fetal and maternal death have been reported during pregnancy. Patients with this surgical history with abdominal complaints should be evaluated thoroughly and without delay, and physical findings consistent with an acute abdomen should be met with a low threshold for surgical consultation and exploration. A large percentage ofpost-bariatric surgery patients will still meet the criteria for being obese during pregnancy, and at continued risk of obesity related adverse perinatal outcomes. Patients should also be counseled that oral contraceptives may be less effective in patients post bariatric surgery with malabsorption, and alternative effective non-oral contraceptive options should be reviewed (Tables 6-4 and 6-5). Pathophyslology In pregnancy, blood volume and cardiac output increase approximately 40% with further increases of cardiac output during labor and delivery, reaching values 80% greater than pre-pregnancy values. Obesity accentuates these changes as blood volume and cardiac output expand in proportion to the increase in body fat and tissue mass. These changes may predispose obese patients to both subtherapeutic and toxic responses to medications. During pregnancy, a state of relative hyperventilation exists, which may be mediated through progesterone. In fact, obese gravidae have markedly diminished functional residual capacity, and except for residual volume, all lung volumes, vital capacity, and total lung capacity are significantly reduced. Furthermore, heightened demand for ventilation, elevated work of breathing, respiratory muscle inefficiency, and diminished respiratory compliance have been shown. Ventilation to perfusion ratio abnormalities and hypoxemia, especially in the supine position further demonstrate the potential adverse impact of obesity on maternal respiratory physiology. These respiratory changes in the obese parturient cause the work of breathing to be increased 3 times normal. Desaturation occurs more rapidly with apnea, as during apnea, oxygen requirements are provided by the functional residual capacity, which as noted, is significantly reduced. With diminished functional residual capacity and increased oxygen requirement, preoxygenation prior to intubation is particularly relevant. A low threshold for the evaluation of sleep disorders, pulmonology consultation, sleep medicine consultation, and maternal echocardiography is suggested when clinical history is suggestive. The increase in cardiac work in these patients should also be considered in evaluation of underlying cardiac dysfunction. Physiology: Obesity and Cardlopulmonary Function Diminished lung volumes and capacities Decreased lu~chest wall compliance Decreased breathing efficiency/gas exchange Relative hypoxia Pulmonary shunt ~ cardiac compensation Blood/plasma volume ~ t cardiac work lschemia/infarction ~. The obstetrician, nurse midwife, labor and delivery nurse, obstetric anesthesiologist, and nurse anesthetist should have the unified focus of achieving the best perinatal outcome possible. Maternal-Fetal Medicine specialists often serve as an integral component of this team. Given the significant intrapartum risks that may occur in these patients, and the challenges intubation may pose, it would be reasonable to consider. Maternal transport or prenatal referral to physicians who work in a tertiary care environment may critical for such patients. Additionally, there may be specific equipment needs to accommodate the obese patient (eg, wider and stronger operating tables, wheelchairs, lifts, longer instruments, large blood pressure cuffs, large pneumatic compression devices), and as such, obstetrical departments should be prepared accordingly. This cannot be overemphasized, as it has been reported that obesity is a significant variable in anesthesia-related maternal mortality, and the inability to accomplish endotracheal intubation is often cited. Securing intravenous access and accurate blood pressure monitoring may also prove challenging due to the obese body habitus. The use of central venous access and an arterial line may be helpful in individual cases. Clinicians tending to patients with extreme obesity in labor are encouraged to delineate a clear plan in their minds for procuring additional surgical assistance, should cesarean section be required or other intrapartum complications arise. Continuous pulse oxirnetry will provide the clinician with important information with respect to maternal oxygen saturation and allow for ongoing evaluation ofhypoxemia and guide the administration of supplemental oxygen as needed, with the goal of maintaining saturation levels at more than or equal to 95%. Labor abnormalities are not uncommon, and close evaluation of the conduct oflabor is warranted. Obese women are at greater risk for delivering a macrosomic infant, and therefore attendants must be prepared for the potential complication of shoulder dystocia, as well as postpartum hemorrhage and fourth degree vaginal lacerations, which often require additional retraction and surgical assistance, to achieve a successful repair. Another important aspect of labor management includes maximizing pulmonary function and decreasing myocardial oxygen requirements. Epidural anesthesia decreases respiratory work, improves oxygenation, and by relieving pain, can decrease the release of catecholamines, which cause increased cardiac work (output); all beneficial attributes. Perhaps the most important aspect of epidural anesthesia lies in the fact that in an emergent situation, should cesarean section be required, a regional anesthetic can be administered through the existing catheter to achieve surgical level anesthesia. This is critically important as historically, difficult intubation has been noted in approximately 6% of women undergoing cesarean section, failed intubation occurs approximately 10 times more often than that observed in general surgical patients, and 90% of maternal deaths from anesthetic causes are attributed to general anesthesia, primarily due to complications of aspiration ofgastric contents and failed endotracheal intubation. While recent reductions in the general anesthesia-related maternal mortality have been noted, it has also been currently observed that among all delivery deaths attributed to complications of anesthesia, 86% occur among women undergoing a cesarean section, with nearly twice the case-fatality rate noted for anesthesiarelated deaths associated with general anesthesia. Thus, the literature would indicate a significantly lower risk of maternal mortality in women undergoing cesarean section under regional anesthesia.

A meta analysis of 38 articles demonstrated a significant improvement of blood lipid profiles following intake of soy proteins [5,6]. In an experiment in old adult rats, -conglycinin intake strongly lowered plasma triglyceride levels through suppression of triglyceride synthesis in the liver and of dietary fatty acid absorption in the intestine [25]. Similar phenomena induced by -conglycinin consumption were shown in diabetic fatty rodents [26]. The mechanism of lowered blood triglycerides is thought to be related to activation of acyl-CoA oxidase, which controls hepatic fatty acid beta-oxidation, and suppression of fatty acid synthase. In oral administration tests of dietary glucose in normal rats, a significant suppression of the hyperglycemic effect was observed following -conglycinin intake, suggesting progression of glucose metabolism in several tissues. In addition, -conglycinin induced significant suppression of blood glucose levels in insulin tolerance tests. These results demonstrated that the skeletal muscle, which makes up 60% of body tissues, is the main organ of glucose metabolism and enhance glucose uptake in the muscle by consumption of -conglycinin. The decrease in triglyceride release from the liver through -conglycinin intake is thought to prevent hypertriglyceridemia. Moreover, intake of -conglycinin suppresses hepatic triglyceride synthesis, and this process depends on the concentration of insulin. Thus, the reduction of triglyceride release from the liver is assumed to be related to blood triglyceride suppression by -conglycinin [27]. In 3T3-L1 adipocytes, hydrolysis of -conglycinin, but not glycinin, promotes adiponectin production and suppresses fat accumulation [46]. In general, the production of adiponectin is negatively correlated with the fat content of adipose cells [38,39]. The suppression of lipid accumulation in the fat pad induced by -conglycinin may increase adiponectin levels [28]. Indeed, feeding of -conglycinin for 4 weeks was found to increase plasma adiponectin levels and improve glucose tolerance (oral glucose tolerance tests and insulin tolerance tests) [27]. In addition, the results of respiratory quotient analysis showed that -conglycinin-induced upregulation of glucose metabolism was closely related to the increase in adiponectin [35]. These results suggested that the ingested glucose energy was used without being converted into fatty acids, an optimized form of energy accumulation. Thus, the lower lipid utilization in the respiratory quotient was induced by the decrease in internal fat accumulation following -conglycinin consumption. In contrast to the glucose uptake enhancement and hypoglycemic activity of -conglycinin, plasma insulin levels were significantly lower following consumption of -conglycinin than those of the control. Therefore, regulating blood glucose by -conglycinin facilitates improvement of glucose metabolism in skeletal muscle, which does not cause insulin overload. Feeding a diet containing mung bean protein to normal rats decreases plasma insulin levels and blood triglyceride levels through suppression of fatty acid synthesis in the liver [57]. Additionally, consumption of mung bean protein has been shown to alleviate symptoms of nonalcoholic fatty liver [58]. Interestingly, despite administration of a mixture containing the same amino acid composition as that of mung bean protein, the mixture had no triglyceride-lowering effects. These findings suggested that mung bean protein may also include functional peptides having physiological effects similar to those of -conglycinin. Therefore, the mung bean 8S globulin, similar to -conglycinin, is also likely to improve glucose metabolism in skeletal muscle. Intake of -conglycinin affects various metabolic phenomena, such as lowering blood triglyceride levels, decreasing body fat, and normalizing glucose homeostasis. Artificial enzyme-hydrolyzed -conglycinin peptides promote uptake of 2-deoxyglucose, a glucose analog, accompanied by translocation of glucose transporter 4 in skeletal L6 myotubes. In either case, there is no doubt that -conglycinin plays an important role in various organs by affecting metabolism in skeletal muscle. Further studies will clarify what is the key factor of the -conglycinin and how -conglycinin modulates the glucose metabolism in the skeletal muscle.

In some cases medicine 9 minutes cheap pepcid 40mg, amyloid is confined to a single organ including bowel medicine 0829085 buy cheap pepcid 40mg, bladder medicine expiration dates discount pepcid 40mg free shipping, and upper airways; these localized disorders are not usually associated with kidney disease medications and grapefruit pepcid 20mg discount. Amyloid deposits can also be found in virtually all other organs including the rectum medications similar to xanax buy pepcid 20 mg cheap, abdominal fat pad treatment glaucoma generic pepcid 20mg online, and the bone marrow, and these are sometimes biopsied in preference to the kidney. The glomerular changes are heterogeneous and range from mild mesangiopathic changes to a mesangiocapillary (membranoproliferative) pattern with features similar to diabetic nodular Downloaded for Daisy Sahni (daisy sahni@rediffmail. The glomerulus shows marked mesangial expansion with amorphous deposits with loss of mesangial argyrophilia (arrows). Electron microscopy shows randomly arranged parallel bundles of straight fibrils (magnification 312,500). There is a heavy concentration of single light chain deposits along the outer aspect of the tubular basement membrane (immunofluorescence microscopy with antibody to single light chain 325). Electron microscopy shows a band of dense granules usually in the inner position of the lamina densa of the glomerular basement membrane and the outer aspect of the tubular basement membrane. Fibrillary and immunotactoid glomerulonephritis are very uncommon non-amyloid (Congo red negative) forms of Ig-associated kidney disease with abnormal tissue deposits from fibrils. Fibrillary glomerulonephritis does not usually associate with a paraprotein and has polyclonal IgG deposits, whereas immunotactoid disease may be associated with hematologic disorders (lymphoma, leukemia) and have monoclonal IgG or IgG deposits and in some cases a circulating paraprotein. The treatment of fibrillary disease is often attempted with steroids and cytotoxics, but the response is poor. Immunotactoid disease may respond to treatment of the underlying hematologic disorder. Progression to end-stage kidney disease is frequent and can occur within a few years. Since the disease remains incurable with a high chance of recurrence, kidney transplant is rarely considered appropriate. Patients with myeloma most frequently present with the signs and symptoms of kidney failure, anemia, or malignant bone pain, typically low back pain unrelieved by rest or simple analgesics. Myeloma cast nephropathy is a medical emergency and requires immediate diagnosis and early institution of therapy in order to prevent irreversible kidney failure. Amyloidosis is due to deposition of fibrils within the body, especially the kidney, heart, liver, nerves, and gut. Primary amyloidosis is associated with myeloma in,10% of patients and the majority present with edema and nephrotic syndrome.

International Myeloma Working Group updated criteria for the diagnosis of multiple myeloma. Paraprotein-related kidney disease: Diagnosing and treating monoclonal gammopathy of renal signficance. Patients with multiple myeloma have excellent long-term outcomes after recovery from dialysis-dependent acute kidney injury. Approximately 63% and 65% of diagnoses and deaths, respectively, occurred in males. In the setting of metastatic disease, patients may note bone pain, palpable adenopathy, or pulmonary complaints. Clinically, this may manifest in a range of symptoms and laboratory abnormalities including, but not limited to , hypertension (24%), hypercalcemia (10% to 15%), and erythrocytosis (4%). In approximately 50% of cases, somatic mutations occur, and in 10% to 20% of cases, the gene is hypermethylated. The resulting tumors are classified as papillary type 1 and are often multifocal and bilateral. If urothelial carcinoma is suspected, urine cytology or ureteroscopy should be considered. For example, patients with T1a disease are recommended to receive history and physical and labs every 6 months for 2 years, and annually up to 5 years. Nephron-sparing surgery is appropriate in selected patients who have multiple primaries, a uninephric state, or kidney disease. Nephron-sparing techniques may also be used in selected patients with small unilateral tumors. With improvements in systemic therapy, the rates of brain metastasis are steadily increasing. This is because the brain remains a "sanctuary site," where penetration of systemic therapy is highly variable. Two multikinase inhibitors with affinity for a number of oncogenic drivers are lenvatinib and cabozantinib. All patients who experienced a partial response (12%) were noted to relapse, with a median duration of response of 15. In contrast, 19 of 23 patients who experienced a complete response remained disease free with a median follow-up ranging between 24 and 221 months. The most commonly reported moderate-to-severe side effects in the pivotal trial of sunitinib were hypertension, fatigue, diarrhea, and hand-foot syndrome. Similarly, diarrhea, rash, fatigue, and hand-foot skin reactions were the most frequently reported adverse events in the pivotal trial of sorafenib. For this reason, this combination may supplant everolimus monotherapy in the previously treated setting. Among the three treatment arms, temsirolimus was associated with improved overall survival. The practitioner should be aware of potential autoimmune sequelae with novel checkpoint inhibitors. These include, for instance, autoimmune colitis, hepatitis, hypophysitis, thyroiditis, arthritis, and hepatitis. It is recommended that, in addition to surveillance for clinical manifestations of these symptoms, patients have frequent monitoring of hepatic and thyroid function. Prompt institution of steroids is recommended if these symptoms are recognized and other pertinent causes are excluded. Salient to the theme of this text is autoimmune nephritis, which occurs sporadically but can be marked by rapid decline in kidney function. Biopsy can be used to diagnose autoimmune nephritis, with heavy immune infiltration of nephrons seen on pathology. The incidence of renal cell carcinoma has been steadily increasing with increased use of computerized tomography and other radiographic studies for diagnosing abdominal conditions. Management of localized renal cell carcinoma largely entails surgical resection of the primary site and possibly adjacent lymph nodes. Systemic therapy for metastatic renal cell carcinoma can be broadly divided into two categories: targeted therapy and immunotherapy. Targeted therapy entails agents that block the vascular endothelial growth factor signaling pathway, while novel immunotherapies target programmed death inhibitor-1, thereby decreasing T-cell anergy. Vascular endothelial growth factor pathway inhibitors can cause hypertension and proteinuria. Novel immunotherapeutic agents, such as programmed death-1 inhibitors, can cause a wide range of immune-related side effects, including autoimmune nephritis. Lenvatinib, everolimus, and the combination in patients with metastatic renal cell carcinoma: A randomised, phase 2, open-label, multicentre trial. The direct antiglobulin test (Coombs test) is negative because the anemia is nonimmune in nature. Shiga toxin binds to vascular endothelial cells, renal mesangial cells, and renal epithelial cells, leading to cell damage. The deficiency leads to large multimers of von Willebrand factor that increase the risk of platelet thrombi in small vessels. The kidney failure and other clinical manifestations (including thrombocytopenia and neurologic manifestations) develop after the diarrhea has begun to resolve. If neurologic abnormalities and hypertension occurred, they can persist even after the acute phase is over. This entails aggressive supportive care including hydration with intravenous fluids, supporting the anemia, and managing the renal failure with renal replacement therapy, if needed. C3b deposition in tissues leads to formation of the C5b-9 terminal complement complex, which in turn leads to injury of normal cells. Complement genetic studies are now commercially available and may be helpful to confirm the diagnosis, as well as provide prognostic information. Medications such as calcineurin inhibitors (tacrolimus and cyclosporine), chemotherapeutic agents. Eculizumab is a humanized monoclonal antibody directed against C5 of the complement cascade and thereby inhibits the formation of C5a and C5b-9 membrane attack complex. The ongoing considerations with regards to eculizumab use are the high cost of the medication and no clear criteria of when to stop the medication. Plasmapheresis remains a part of initial therapy because there may be a delay in diagnosis and/or obtaining the drug. Prophylactic treatment with eculizimab has been discussed as a therapeutic option. The overactivation of the pathway occurs either via a genetic mutation or autoantibodies to a regulatory protein. Shiga toxin-producing Escherichia coli infection, antibiotics, and risk of developing hemolytic uremic syndrome: A meta-analysis. Clinical onset in affected males with the Type 1 Classic phenotype occurs in childhood or adolescence and is characterized by painful acroparesthesias, gastrointestinal dysfunction, corneal dystrophy, absent or decreased sweat (anhidrosis or hypohidrosis), and cutaneous lesions (angiokeratomas). With advancing age, the progressive glycolipid accumulation, especially in podocytes and cardiomyocytes, leads to kidney failure, cardiac disease, ischemic strokes, and early demise. Female heterozygotes from Type 1 Classically affected families can be as severely affected as Type 1 Classically affected males, or may be asymptomatic throughout life, primarily as a result of random X-chromosomal inactivation. Patients with the Type 2 Later-Onset phenotype lack the childhood manifestations of the Type 1 Classic early-onset phenotype and often are unrecognized. Previously undiagnosed males with both Types 1 and 2 Fabry disease have been identified in hemodialysis, cardiac, and stroke clinics by screening patients for markedly deficient plasma a-Gal A activity. Since the disease is X-linked, at-risk family members should be screened, and affected patients should receive genetic counseling, medical evaluations, and early therapeutic intervention, especially in males with the Type 1 Classic phenotype. The two major subtypes of Fabry disease are the Type 1 Classic and Type 2 Later-Onset phenotypes. The phenotypic subtypes are determined by the specific a-Gal A mutation; thus, all affected family members will have the same phenotypic subtype. Affected males with the Type 1 Classic phenotype have little, if any, a-Gal A enzyme activity (,1% of mean normal), whereas males with the Type 2 LaterOnset phenotype have residual enzymatic activity, typically. Heterozygous females from Type 1 Classic Fabry families have a wide range of clinical manifestations from asymptomatic to severely affected, whereas heterozygous females from Type 2 Later-Onset families may have symptoms later in life, including cardiac and kidney manifestations. Heterozygotes from Type 2 Later-Onset families are likely to be less involved clinically, but can have as severe manifestations as their affected male relatives. Newborn screening studies have revealed that the Type 2 Later-Onset patients are more commonplace than patients with the Type 1 Classic phenotype. Type 1 Classically affected males have mutations that result in essentially no enzymatic activity, whereas patients with the Type 2 Later-Onset phenotype have mutations that retain low levels of residual enzyme activity. For both phenotypes, the sons of affected males will not have the disease, whereas all daughters will be heterozygotes. The deficient or absent a-Gal A activity results in the accumulation of glycolipids with terminal a-linked galactose molecules. The major pathology leading to kidney failure results from the glycosphingolipid accumulation in the kidney microvascular endothelial cells, interstitial, mesangial, tubular cells, and particularly in the podocytes. In the Type 2 Later-Onset patients the kidney pathology results primarily from glycolipid accumulation in the podocytes. Clinical manifestations in Type 1 Classically affected males begin in childhood or adolescence. Most often, the first symptoms are painful acroparesthesias (especially during febrile illnesses); hypohidrosis; and gastrointestinal symptoms, including postprandial abdominal cramping, bloating, and diarrhea. Small petechial-like angiokeratomas, the classic cutaneous vascular lesions, typically are present in the umbilical and swimsuit regions in childhood. Type 1 Classically affected males also have a distinctive corneal dystrophy observed by slit-lamp microscopy, which does not affect vision. Dialysis and kidney transplantation are effective in correcting the kidney disease, and kidney transplants are not affected by the disease. All potential family donors should be evaluated to ensure that they are not affected or heterozygotes. Cardiac manifestations include arrhythmias (initially sinus bradycardia), valvular abnormalities, and left ventricular hypertrophy, which may lead to hypertrophic cardiomyopathy. Cerebrovascular disease manifests as transient ischemic attacks and stroke: the strokes often result from the cardiac arrhythmias. Progressive high-frequency hearing loss occurs in Type 1 Classically affected males in the third to fifth decades of life.
