The of publications reporting the association between female infertility and obesity. Thegreat increase in number of reports appeared per year since 1980 reveals that the interest in the topic great increase in number of reports appeared per year since 1980 reveals that the interest in the topichas increased during the last decades. There is a body of literature pointing out the role of lipidsfor female fecundity; indeed, cholesterol and fatty acids are determinant for reproductive function for female fecundity; indeed, cholesterol and fatty acids are determinant for reproductive functionat the level of ovary, uterus and placenta [ at the level of ovary, uterus and64– 66placenta]. Recently, serum free cholesterol concentrations,both women and men, have been associated with reduced fecundity [ in both women and men, have been associated with67 reduced]. Using this model, the authors clearlya hepatic-ovarian axis necessary for female reproductive function. This mechanism has never been showed the existence of a hepatic‐ovarian axis necessary for female reproductive function. Thisextensively studied although it could be a key in linking reproduction with metabolism. A recent work mechanism has never been extensively studied although it could be a key in linking reproductionperformed in our laboratory revealed that, in female mice, the estrous cycle coordinates cholesterol with metabolism. Altogether, these data further highlight that the influence of metabolism on reproduction is bidirectional. Finally, insulin resistance is often correlated with obesity; the effect of this pancreatic hormone on female fertility has been extensively studied and is reviewed in the next section.

Insulin and Adipokines: the Most Involved Molecular Players Linking Obesity and Reproductive Impairment From what is said above, it appears clear that energy metabolism and female fertility are tightly connected and reciprocally regulated. Not surprisingly many peripheral signals report nutritional Nutrients 2016, 8, 87 5 of 34 5. Insulin and Adipokines: the Most Involved Molecular Players Linking Obesity and Reproductive Impairment NutrientsFrom what is said above, it appears clear that energy metabolism and female fertility are tightly 2016, 8, 87 5 of 32 connected and reciprocally regulated. Insulin Insulin has long been known as a peripheral regulator of energy homeostasis: this hormoneInsulin has long been known as a peripheral regulator of energy homeostasis: this hormone controls glucose uptake, oxidation and storage [controls glucose uptake, oxidation and storage72 [72]. In particular, once secreted by pancreatic In particular, once secreted by pancreaticβ cells in β cells response to increased blood glucose levels, insulin stimulates glucose uptake by the skeletal musclein response to increased blood glucose levels, insulin stimulates glucose uptake by the skeletal and by the adipose tissue and regulates lipid metabolism in the liver. Pancreatic β cells try toβ counteractcells try to counteract insulin resistance by enhancing their mass and insulin resistance by enhancing their mass and secretory secretory activity; however, when the functional expansion of isletactivity; however, when the functional expansion of islet β‐cellsβ-cells fails to compensate, insulin fails to compensate, insulin deficiency and ultimately type 2 diabetes (T2D) develop [74]. T2D incidence is approximately 90% lower in middle‐age women with a normal weight, who exercise regularly and eat a diet rich in cereal fiber and in poly‐unsaturated fats and poor in saturated and trans fats [75]. This pathology is often characterized by some aberrations in the secretion of gonadotropins and, in particular, with high Nutrients 2016, 8, 87 6 of 34 deficiency and ultimately type 2 diabetes (T2D) develop [74]. T2D incidence is approximately 90% lower in middle-age women with a normal weight, who exercise regularly and eat a diet rich in cereal fiber and in poly-unsaturated fats and poor in saturated and trans fats [75]. Moreover, insulin, through its own receptor, has been demonstrated to have direct effect on steroidogenesis in the ovaries [79]. Under physiological conditions, insulin acts as a co-gonadotrophin in theca cells; on the other hand, hyperinsulinemia potentiates gonadotropin-stimulated ovarian androgen synthesis [87,88]. All the treatments aimed at reducing insulin levels, such as weight loss and insulin sensitizers, improve female reproductive health. On the other hand, type 1 diabetes (T1D) is a condition in which pancreatic β-cells destruction leads to absolute insulin deficiency [90]. Hypogonadotropic hypogonadism is present in women with uncontrolled type 1 diabetes [91] and, despite a significant improvement in the therapy for T1D, patients still experience abnormalities in pubertal development, menstrual cycle and menopause age [92]. Experimental evidence further supported the clinical data showing that insulin plays an important role in the regulation of female fertility.

We have shown that the costs of fertility treatment and of pregnancy complications in obese women compared to women of normal weight, were 6045 and 3016 in anovulatory women and 10,355 and 6096 in ovulatory women per live birth, respectively. Obesity, adipose tissue dysfunction and body-fat redistribution In women of reproductive age with obesity and infertility, it is essential to identify women with abdominal obesity because of its association with infertility and pregnancy complications (Wass et al. When subcutaneous adipose tissue can not store further excess fat due to adipose tissue dysfunction, a process of body-fat redistribution is initiated. In order to increase its storage capacity of excess fat, subcutaneous adipose tissue regulates the recruitment and differentiation of preadipocytes to mature adipocytes (adipogenesis), leading to more adipocytes that can store excess fat (hyperplastic obesity) (Danforth, 2000, Rodriguez-Acebes et al. Hypertrophic obesity is associated with increased fat cell size, necrosis and an inflammatory response (Rasouli and Kern, 2008; Weiss, 2007), resulting in a decreased ability to store additional fat leading to dysfunctional subcutaneous adipose tissue. Dihydrotestosterone decreases the differentiation and lipid accumulation in human preadipocytes and adipocytes in culture (Gupta et al. The role of adipokines Adipose tissue is a complex and highly active endocrine organ involved in the metabolism of steroid hormones and expression and secretion of various proteins and peptides, collectively called adipokines (Ahima, 2006). Redistribution of fat and altered function of all body-fat compartments (including ectopic sites) is reflected in a changing profile of adipokine secretion (Freedland, 2004; Weiss, 2007; Despres et al. On the other hand, serum adipokine levels may not accurately reflect the morphology and function of adipose tissue compartments for the following reasons. Leptin on the other hand is also expressed by other cells within the fat depots and by other tissues. At present it is not possible to define the contribution of ectopic fat depots to serum adipokine levels. Studies on the effect of obesity on female reproduction by analysing serum adipokine levels should take these limitations into consideration. The measurement of serum adipokine levels should not be used in the clinical management of women with obesity and infertility. In Figure 1 an overview is presented of the concept of adipose tissue dysfunction and of the proposed mechanisms by which accumulation and dysfunction of intra-abdominal adipose tissue and subcutaneous adipose tissue can be linked to the metabolic and female reproductive consequences of obesity. In Figure 1 it is also explained why women with hyperplastic obesity can maintain a metabolically healthy obese phenotype. Proposed mechanisms by which accumulation of intra-abdominal and subcutaneous adipose tissue can cause dysfunctional and functional obesity, and be linked to metabolic and female reproductive consequences of obesity. According to a recent systematic review and meta-analysis, dietary and lifestyle intervention even during pregnancy can improve perinatal and obstetric outcomes (Thangaratinam et al. Weight loss interventions for the improvement of reproductive outcome in women with obesity and infertility are based on retrospective and small cohort studies, and have not yet been evaluated in randomised controlled trials. Previous studies have shown that 5‒10% loss of body weight leads to resumption of ovulation in about 60% of anovulatory women who are overweight or obese (Kiddy et al. In Chapter 6, there was a non-significant increase in pedometer steps (an indication of increased physical activity) in the women that resumed ovulation compared to those that remained anovulatory during the lifestyle programme. In women of normal weight, a decrease in fecundability with vigorous physical activity was seen in a dose-response relationship (Wise et al. In women with overweight or obesity however, a weak positive association was seen between vigorous activity and fecundability (Wise et al. Most individuals who are overweight or obese experience great difficulty to achieve and maintain weight loss, and a multi-factorial approach based on diet, exercise and behaviour modification is advised to help patients lose weight (Anonymous, 1998). Dietary interventions should be tailored to individual preferences aimed at achieving a 600 kcal/day deficit. Generally, obese individuals achieve maximal weight loss after the first 6 months of weight loss intervention irrespective of the dietary composition (Sacks et al. According to a meta-analysis, exercise in combination with dietary intervention achieves more weight loss than diet alone (Wu et al.

This faint aortic diastolic murmur might be overlooked unless one listens with the patient sitting upright medicine nelly buy chloroquine cheap, leaning forward medicine man pharmacy order chloroquine 250mg visa, breath held in deep expiration symptoms vaginal cancer 250mg chloroquine for sale, applying firm enough pressure on the diaphragm of the stethoscope to leave an imprint on the chest wall. Aortic or pulmonic regurgitation results in an early diastolic murmur due to back flow through the aortic or pulmonic valves during diastole. To simulate the murmur, the clinician should purse his or her lips tightly and blow. Most commonly, the diastolic murmur is loudest along the left sternal border and aortic area 15). When the diastolic murmur is musical (“cooing dove” murmur), it usually signifies eversion or perfo- ration of an aortic cusp, as may occur with infective endocarditis. A careful search is needed to properly elicit the murmur, with the patient sitting upright and leaning forward, with the breath held in full expiration, and the examiner applying firm pressure on the diaphragm of the stethoscope, enough to leave an imprint on the skin. When loud, the systolic flow murmur may distract the inexperienced clinician from the subtle but diagnostic diastolic murmur. This position moves the heart closer to the chest wall and is also especially useful to detect a pericardial friction rub and enhance the intensity of heart sounds and murmurs in some patients having a pericardial effusion. The clinician should keep in mind that patients having a slight leak of the aortic valve can be completely asymptomatic. It is only when the leak becomes significant that the murmur, being louder, is heard, and other symptoms and signs occur. The clinical presentation of a regurgitant pulmonary valve varies depending on whether pulmonary artery pressure is normal or elevated. Pulmonary valve insufficiency with normal pulmonary artery pressure is usually the result of congenital valve insufficiency, in association with idiopathic dilatation of the pulmonary artery. The murmur is usually of low or medium frequency, best heard at the second left interspace or left sternal border. It starts at some interval immediately after P2, most often has a crescendo-decrescendo configuration, and increases with inspira- tion. In the congenital variety, all clinical parameters other than the murmur may be normal. Murmurs resulting from tur- bulent flow across the mitral valve tend to be of low frequency and thus are best heard with the bell of the stethoscope lightly applied at the cardiac apex with the patient in the left lateral position. The early to mid diastolic 17) part occurs during the phase of early ventricular filling; the presystolic accentuation of the murmur occurs in patients with sinus rhythm during the phase of atrial contraction (but has been reported even with atrial fibrillation). The duration of the murmur is more reliable than its intensity as an index of the severity of valve obstruction. Improper positioning and/or use of the bell of the stethoscope are important reasons. Frequently, the murmur is confined to a very small area (the size of a quarter) over the cardiac apex, and the bell of the stethoscope must be applied over this small area with the patient turned to the left. The left lateral decubitus position brings the apex closer to the chest wall and overlying stethoscope, which increases the audibility of the low intensity murmur. If the murmur is not audible, exercise (eg, sit-ups) may increase mitral flow and “bring out” the murmur. As a right-sided event, inspiratory augmentation in intensity of the murmur helps to distinguish its tricuspid valve origin. Continuous murmurs last throughout all of systole and continue uninterrupted into at least early diastole. They are generated by continuous flow from a vessel or chamber with high pressure into a vessel or chamber with low pressure. Continuous jugular venous hums are frequently heard in children and young adults, especially during pregnancy (along with the mammary arterial souffle—a systolic/diastolic murmur due to blood flow through the superficial mammary arteries heard over the breast in late pregnancy and lactation), and in thyrotoxicosis, in anemia, or in persons with a hyperdynamic circulatory state. These innocent venous hums are best heard over the right internal jugular vein at the base of the neck with the patient’s head turned to the opposite direction (“on a stretch”) but occasionally may be loud enough to be transmitted to the upper chest where they may be confused with a serious cardiac murmur 18). Gentle pressure over the jugular vein generally eliminates the hum, as does turning the patient’s head to the forward position. The mammary souffle can usually be obliterated with firm pressure applied to the diaphragm of the stethoscope over the engorged breast. A venous hum can best be heard by listening with the bell of the stethoscope over the right supraclavicular fossa with the patient’s head turned upward and to the left (“on a stretch”). Gentle pressure over the jugular vein generally eliminates the hum, as does turning the patient’s head to the forward position.
