AI Article Synopsis

  • The study aimed to evaluate the time to intubation and glottic visualization using three types of laryngoscopes in morbidly obese patients.
  • Forty-five morbidly obese patients were split into three groups, and the time to intubation and difficulty scores were compared among the Macintosh, McCoy, and Glidescope video laryngoscopes.
  • Results showed that the Glidescope took significantly longer to intubate without any benefits in difficulty scores or hemodynamic responses, suggesting that the Macintosh laryngoscope is the preferred option due to its effectiveness and availability.

Article Abstract

Objectives: The aim of the study was to compare time to intubation and glottic visualization between Macintosh, McCoy, and Glidescope video laryngoscope (GVL) in morbidly obese patients.

Methodology: Forty-five American Society of Anesthesiologists I-III morbidly obese patients were randomized into three groups of 15 each and time to intubation, Cormack-Lehane grading, and Intubation Difficulty Score (IDS) were compared.

Results: GVL took more time to intubate (TTI) compared to Macintosh and McCoy laryngoscope ( = 0.0001). Overall IDS were similar between the groups.

Conclusion: To conclude, GVL takes longer TTI with no added advantage in IDS and hemodynamic response to intubation in morbidly obese patients. McCoy is only as effective as Macintosh and hence Macintosh laryngoscope should be laryngoscope of choice due to its widespread availability and familiarity.

Recent studies have suggested that the interaction between diet and an individual's genetic predisposition can determine the likelihood of obesity and various metabolic disorders. The current study aimed to examine the association of dietary branched-chain amino acids(BCAAs) and aromatic amino acids(AAAs) with the expression of the leptin and FTO genes in the visceral and subcutaneous adipose tissues of individuals undergoing surgery. This cross-sectional study was conducted on 136 Iranian adults, both men and women, aged ≥18 years.

The effectiveness of bariatric surgery in reducing remnant cholesterol (RC) levels, particularly when obesity is accompanied by elevated glycated hemoglobin (HbA1c), is insufficiently investigated. In this study, we aimed to examine the impacts of two common bariatric procedures, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), as regards their effects on RC and HbA1c levels. Adult morbidly obese subjects were included and assigned to receive either RYGB or SG.

The connections between sarcopenia and various chronic conditions, including type 2 diabetes (T2DM), metabolic syndrome (MetS), and liver disease have been highlighted recently. There is also a high occurrence of sarcopenia in metabolic dysfunction-associated steatotic liver disease (MASLD) patients, who are often disregarded. Both experimental and clinical findings suggest a complex, bidirectional relationship between MASLD and sarcopenia.

Background: MyBFF@school program consisting physical activity in the formed small-sided games (SSG), nutrition and psychology education was designed to combat obesity among schoolchildren in Malaysia. It was expected to improve cardiorespiratory fitness, hence, contributing to obesity treatment and prevention. Thus, we aimed to study the effects of the MyBFF@school program on the cardiorespiratory fitness of overweight and obese primary schoolchildren.
