In recent decades, the worldwide prevalence of obesity has risen dramatically and is currently estimated to be around 20%. Obesity linked an increased risk comorbidities premature mortality. Several studies have shown that negatively impacts male fertility through various mechanisms. This review aims investigate molecular mechanisms which impairs reproduction, including obesity-associated hypogonadism its effects on spermatogenesis, chronic inflammation, oxidative stress. both conventional biofunctional sperm parameters, it also induces epigenetic changes can transferred offspring. Moreover, obesity-related diseases are a dysregulation adipocyte function micro-environmental inflammatory processes. The dysregulated adipokines significantly influence insulin signaling, they may detrimental effect testicular function. Sirtuins play important role in metabolic responses obese patients. Understanding involved obesity-induced infertility could increase our ability identify novel targets for prevention treatment related consequences.

Obesity must be considered a real pathology. In the world wide, obesity represent one of major public health issue associated with increased morbidity and mortality. Overweight or obesity, in fact, significantly increases risk contracting diseases, such as: arterial hypertension, dyslipidemia, type 2 diabetes mellitus, coronary heart disease, cerebral vasculopathy, gallbladder lithiasis, arthropathy, ovarian polycytosis, sleep apnea syndrome, some neoplasms.

<b><i>Background:</i></b> The very low-calorie ketogenic diet (VLCKD) has been recently proposed as an appealing nutritional strategy for obesity management. VLCKD is characterized by a low carbohydrate content (&#x3c;50 g/day), 1–1.5 g of protein/kg ideal body weight, 15–30 fat/day, and daily intake about 500–800 calories. <b><i>Objectives:</i></b> aim the current document to suggest common protocol summarize existing literature on its efficacy in weight management weight-related comorbidities, well possible side effects. <b><i>Methods:</i></b> This prepared adherence with Preferred Reporting Items Systematic Review Meta-Analyses (PRISMA) guidelines.

Importance

Antibody blockade of activin type II receptor (ActRII) signaling stimulates skeletal muscle growth. Previous clinical studies suggest that ActRII inhibition with the monoclonal antibody bimagrumab also promotes excess adipose tissue loss and improves insulin resistance.

Objective

To evaluate efficacy safety on body composition glycemic control in adults 2 diabetes overweight obesity.

Design, Setting, Participants

This double-masked, placebo-controlled, 48-week, phase randomized trial was conducted among diabetes, mass index between 28 40, glycated hemoglobin (HbA1c) levels 6.5% 10.0% at 9 US UK sites. The from February 2017 to May 2019. Only participants who completed a full treatment regimen were included analysis.

Interventions

Patients intravenous infusion (10 mg/kg up 1200 mg 5% dextrose solution) or placebo (5% every 4 weeks for 48 weeks; both groups received diet exercise counseling.

Main Outcomes Measures

primary end point least square mean change baseline week total fat (FM); secondary exploratory points lean (LM), waist circumference (WC), HbA1clevel, weight (BW) changes 48.

Results

A 75 patients (n = 37; 23 [62.2%] women) 38; 12 [31.6%] women); 58 (77.3%) 48-week study. had (SD) age 60.4 (7.7) years; BMI 32.9 (3.4); BW 93.6 (14.9) kg; FM 35.4 (7.5) HbA1clevel 7.8% (1.0%). Changes vs as follows: FM, −20.5% (−7.5 kg [80% CI, −8.3 −6.6 kg]) −0.5% (−0.18 −0.99 0.63 (P < .001); LM, 3.6% (1.70 1.1 2.3 −0.8% (−0.4 −1.0 0.1 WC, −9.0 cm (80% −10.3 −7.7 cm) 0.5 −0.8 1.7 −0.76 percentage −1.05 −0.48 points) 0.04 −0.23 0.31 .005); BW, −6.5% (−5.9 −7.1 −4.7 (−0.8 −1.9 0.3 .001). Bimagrumab’s tolerability profile consistent prior studies.

Conclusions Relevance

In this trial, led significant gain metabolic improvements during obesity diabetes. pathway may provide novel approach pharmacologic management adiposity accompanying disturbances.

Obesity in adolescence has reached epidemic proportions around the world, with prevalence of severe obesity increasing at least 4-fold over last 35 years. Most youths carry their excess adiposity into adulthood, which places them increased risk for developing obesity-driven complications, such as type 2 diabetes and cardiovascular disease, negatively affects social emotional health. Given that is a unique transition period marked by significant physiologic developmental changes, obesity-related complications can also affect adolescent growth trajectories.

Abstract Obesity contributes 65–75% of the risk for human primary (essential) hypertension (HT) which is a major driver cardiovascular and kidney diseases. Kidney dysfunction, associated with increased renal sodium reabsorption compensatory glomerular hyperfiltration, plays key role in initiating obesity-HT target organ injury. Mediators dysfunction blood pressure include (i) elevated sympathetic nerve activity (RSNA); (ii) antinatriuretic hormones such as angiotensin II aldosterone; (iii) relative deficiency natriuretic hormones; (iv) compression by fat around kidneys; (v) activation innate adaptive immune cells that invade tissues throughout body, producing inflammatory cytokines/chemokines contribute to vascular injury, exacerbate HT. These neurohormonal, renal, mechanisms are interdependent. For example, excess adiposity increases adipocyte-derived cytokine leptin RSNA stimulating central nervous system proopiomelanocortin-melanocortin 4 receptor pathway. Excess visceral, perirenal sinus compress kidneys which, along RSNA, renin–angiotensin–aldosterone activation, although obesity may also activate mineralocorticoid receptors independent aldosterone. Prolonged obesity, HT, metabolic abnormalities, inflammation cause progressive making HT more resistant therapy often requiring multiple antihypertensive drugs concurrent treatment dyslipidaemia, insulin resistance, diabetes, inflammation. More effective anti-obesity needed prevent cascade cardiorenal, metabolic, disorders threaten overwhelm health care systems prevalence continues increase.
