- Abnormalities of Reproductive Function in Male Obesity Before and After Bariatric Surgery-A Comprehensive Review(2015) ROSENBLATT, Alberto; FAINTUCH, Joel; CECCONELLO, IvanYoung males represent one of the populations with the steepest increases in the incidence of obesity. They are also prone to significant derangements in sexual health and fertility. Despite a growing number of reports about female reproductive health, in the setting of bariatric surgery, males have received much less attention. In the current review of reproductive abnormalities in severe obese males before and after bariatric surgery, erectile function, hypothalamic-pituitary-gonadal axis status, sex hormones, semen quality, fertility and assisted reproductive techniques, along with analysis of adipokines, gut hormones, and environmental factors are addressed. Available evidence about weight loss benefits, both medical and surgical, are highlighted, along with perspectives for future investigations, which may be relevant for the patient, for the couple, and for the community alike.
- Is the skeleton still in the hospital closet? A review of hospital malnutrition emphasizing health economic aspects(2015) SOUZA, Telma T.; STURION, Claudio J.; FAINTUCH, JoelBackground: Hospital malnutrition used to be a skeleton, a well hidden secret. Compelling studies in the last four decades revealed the width and depth of the problem. It encompasses not only critically ill hospitalized individuals, but many other vulnerable groups. The aim of this review was to assess the effectiveness of current hospital routines in eradicating this historical scourge. Methods: Diagnosis used to rely on clinical impression or anthropometrics only. Fortunately well structured questionnaires, complemented by biochemical tests and body composition studies whenever necessary, allow precise and reproducible assessment of nutritional risk, in most age brackets and disease modalities. Results: Near the end of the XIXth century many scientists believed that anatomical studies were doomed. Everything that needed to be discovered was already known: muscles, bones, joints, nerves, cardiovascular structures and other systems. Then in 1893, Wilhelm His in Switzerland discovered the eponimous His bundle. In 1906 Sunao Tawara in Japan was responsible for the concept of the atrioventricular conduction pathway. Combined with the advent of the electrocardiograph by Willem Einthoven in The Netherlands, in 1903, such advances extraordinarily improved the handling of heart arrhythmias. Addressing hospital malnutrition does not depend on new technologies. All the essential tools exist and have been clinically tested, as here analyzed. A simpler breakthrough is desired, namely the wider adoption of available procedures. Conclusion: Four decades after a historical report, a barrier still remains in many countries, namely more effectively embedding screening and nutritional therapy tools for hospitalized patients, in the professional routine.
- NUTRITIONAL, METABOLIC AND CARDIOVASCULAR CORRELATIONS OF MORNING CORTISOL IN HEALTH CARE WORKERS IN A GASTROENTEROLOGY SERVICE(2015) GUERRA, Aline; SOARES, Rafael Marques; PEZZI, Fernanda; KARKOW, Francisco Juarez; FAINTUCH, JoelBackground: Workplace stress has been associated with obesity. Diminished body weight has also been anticipated in some contexts. Objective: In a cohort of healthcare personnel, morning cortisol was compared to nutritional and metabolic variables, aiming to identify the correlates of such marker. Methods: Population n=185, 33.8 ± 9.8 years, 88.1% females, body mass index (BMI) 25.6 ± 4.4 kg/m2, included nurses and other nosocomial professionals, the majority with high social-economic status (75.2%). Participants were stratified according to BMI, fasting blood glucose (FBG) and metabolic syndrome (MS). Fasting plasma cortisol and the Framingham Coronary Risk Score was calculated. Results: Mean cortisol was acceptable (19.4 ± 7.9 µg/dL) although with elevation in 21.6%. No correlation with FBG or MS occurred, and nonobese persons (BMI <25) exhibited the highest values (P=0.049). Comparison of the lowest and highest cortisol quartiles confirmed reduced BMI and waist circumference in the former, with unchanged Framingham Coronary Risk Score. Conclusion: Cortisol correlated with reduced BMI. Despite low BMI and waist circumference, Framingham Coronary Risk Score was not benefitted, suggesting that exposure to cardiovascular risk continues, besides psychological strain. Initiatives to enhance organizational and staff health are advisable in the hospital environment.
- The dual burden of obesity and diabetes: Old problems die hard(2015) FAINTUCH, J.; FAINTUCH, S.The array of efforts to control obesity is as wide and diversified as the mechanisms of the disease. From jaw wiring to fecal transfer, there have been virtually no limits for surgical and medical ingenuity. Initial results are always encouraging, if not for other reasons, because some placebo effect is always operative. The patient wants to lose weight, trusts the doctor, and is psychologically motivated, which can be a winning association, at least for a while. That’s why all the tenets of scientific investigation, including not only sound pathophysiological basis but also adequate controls and long-term follow-up, are indispensable. In the present chapter some creative and promising techniques will be reviewed, even though not all of them have been sufficiently tested in the bariatric population, or are ready for application. © Springer International Publishing Switzerland 2015.
