The prevalence of iron deficiency anaemia in patients undergoing bariatric surgery.
As bariatric surgery rates continue to climb, anaemia will become an increasing concern. We assessed the prevalence of anaemia and length of hospital stay in patients undergoing bariatric surgery. Prospective data (anaemia [haemoglobin <12 g/dL], haematinics and length of hospital stay) was analysed on 400 hundred patients undergoing elective laparoscopic bariatric surgery. ⋯ Mean length of stay (days) was increased in the anaemic compared to in the non-anaemic group (2.7 vs. 1.9) and patients who were anaemic immediately post-operatively, also had an increased length of stay (2.7 vs. 1.9), p<0.05. Absolute iron deficiency was more common in patients undergoing bariatric surgery. In bariatric patients with anaemia there was an overall increased length of hospital stay.

Heart failure is a leading cause of morbidity and mortality and its prevalence continues to rise. Because obesity has been linked with heart failure, the increasing prevalence of obesity may presage further rise in heart failure in the future. Obesity-related factors are estimated to cause 11% of heart failure cases in men and 14% in women. ⋯ Direct cardiac lipotoxicity has been described where lipid accumulation in the heart results in cardiac dysfunction inexplicable of other heart failure risk factors. In this overview, we discussed various pathophysiological mechanisms that could lead to heart failure in obesity, including the molecular mechanisms underlying cardiac lipotoxicity. We defined the obesity paradox and enumerated various premises for the paradoxical associations observed in the relationship between obesity and heart failure.

Glucose, insulin, and insulin resistance in normal-weight, overweight and obese children with obstructive sleep apnea.
Obstructive sleep apnea (OSA) is associated with components of metabolic syndrome. Both body weight and OSA independently influence metabolic measurements. The goal of this study was to determine whether OSA in normal-weight, overweight or obese children, compared to matched control groups, was associated with increased levels of glucose, insulin and insulin resistance (IR). ⋯ IR levels between OSA and control for both normal-weight, overweight and obese subjects were not significantly different. The ODI was associated with increased IR in children with OSA. OSA-induced hypoxic events during sleep may be a potential mechanism of increased IR in children with OSA, independent of body weight.

Patient and physician characteristics associated with the provision of weight loss counseling in primary care.
A variety of physician and patient characteristics may influence whether weight loss counseling occurs in primary care encounters. ⋯ These findings add to previous evidence suggesting possible differences in the weight loss counseling practices of male and female physicians, although further research is needed to understand this potential difference between physicians.

Clinical TrialThe impact of physician weight discussion on weight loss in US adults.
The increasing prevalence of overweight and obesity in the United States and worldwide is at epidemic levels. Physicians may play a vital role in addressing this epidemic. We aimed to examine the association of a physician's discussion of patients’ weight status with self-reported weight loss. We hypothesized that physician discussion of patients’ being overweight is associated with increased weight loss in patients with overweight and obesity. ⋯ Physicians’ direct discussion of their patients’ weight status is associated with clinically significant patient weight loss and may be a targetable intervention. Further studies are needed to determine if increasing physician discussion of patients’ weight status leads to significant weight loss.
