Randomized Controlled Trial
Diagnostic accuracy of home-based monitoring system in morbidly obese patients with high risk for sleep apnea.
No previous studies have validated the use of portable monitoring (PM) for the diagnosis of obstructive sleep apnea (OSA) in morbidly obese individuals. Our aim was to investigate the accuracy of PM for detecting respiratory events in morbidly obese patients that will be undergoing bariatric surgery. ⋯ PM is an efficacious method for diagnosing OSA in obese patients who have a high clinical probability of the disease. The method displays good sensitivity and specificity in severe cases; nevertheless, the high rate of data loss must be taken into account.

Many studies quantitatively analyzing scientific papers have appeared in the last 2 years. Citation analysis is a commonly used bibliometric method. In spite of some limitations, it remains a good measure of the impact an article has on a specific field, specialty, or a journal. The aim of this study was to analyze the qualities and characteristics of the 100 most cited articles in the field of bariatric surgery. ⋯ Many of the milestone papers in bariatric surgery have been included in this bibliometric study. A huge increase in research activity during the last decade is clearly visible in the field. It is apparent that the number of citations of an article is not related to its level of evidence; a fact that is increasingly being emphasized in surgical research.

The experience of stigmatization is widespread among obese patients. The aim of the present study was to translate the English version of the weight self-stigma questionnaire (WSSQ) into German and to evaluate the psychometric properties of the German version in a sample of severely obese persons. ⋯ Significant correlations between WSSQ scores and mental quality of life, weight-related quality of life, depression, shame, guilt, and psychological distress all demonstrated the construct validity of the German version of the WSSQ. Patients with a BMI ≥ 50 showed a significantly higher self-stigma compared to patients with a BMI between 35 and 50.

Review Meta Analysis
Long-term effects of bariatric surgery on type II diabetes, hypertension and hyperlipidemia: a meta-analysis and meta-regression study with 5-year follow-up.
The first aim of the study was to estimate weight loss and major modifiable risk factors after bariatric surgery. The second aim was to investigate the relationship between the reduction in cardiovascular risk and weight loss over time. ⋯ The reduction in arterial hypertension reached a nadir earlier than the risk of diabetes and hyperlipidemia, thus indicating a possible link between weight reduction and positive hemodynamic effects.

Randomized Controlled Trial
Intranasal nicotine increases postoperative nausea and is ineffective in reducing pain following laparoscopic bariatric surgery in tobacco-Naïve females: a randomized, double blind trial.
Nicotine is a known analgesic. Our primary aim was to test the hypothesis that intranasal nicotine administered intraoperatively reduces the need for postoperative opioids. The secondary outcomes included evaluation of both postoperative pain and nausea and vomiting (PONV). ⋯ Intraoperative intranasal nicotine did not exhibit opioid-sparing effect in nonsmoking bariatric female patients. Despite antiemetic prophylaxis, the use of nicotine was associated with the higher frequency of the use of rescue antiemetics in PACU.
