AI Article Synopsis

  • - The study examines the relationship between intentional exercise and weight loss in patients who underwent bariatric surgery, noting a lack of research on this topic beyond the first year post-surgery.
  • - Patients were categorized based on their weekly exercise duration, and results showed that those who exercised for more than 200 minutes per week experienced significantly greater weight loss compared to those who exercised less than 90 minutes.
  • - The findings suggest that bariatric surgery teams should encourage patients to maintain a high level of exercise (over 200 minutes per week) for optimal weight loss results in the medium term.

Article Abstract

Background: Exercise is a strong determinant of prolonged weight loss in non-surgical patients. Studies evaluating the impact of exercise beyond the first year after bariatric surgery are lacking. We analyzed the relationship between reported intentional exercise and medium-term weight loss following bariatric surgery.

Methods: Patients who underwent bariatric surgery from 2007 thru 2013 completed a follow-up telephone survey and were separated into groups based on reported weekly exercise, i.e., < 90 min week, 90-200 min week, and > 200 min week. Standardized weight loss measures including percent of total weight loss, percent of excess body mass index (BMI) loss, percent of excess weight loss, and change in BMI were compared using analysis of covariance, with years from surgery as the covariant.

Results: A total of 872 patients were included in this study (age = 48 ± 10 years; BMI = 48 ± 7 kg/m), with a mean post-surgery follow-up of 39 ± 14 months. Patients reporting > 200 min week of planned exercise had greater weight loss than those who did less than 90 min week (p < 0.05). No significant difference was found between those who reported less than 90 min weekand those reporting between 91 and 200 min week.

Conclusions: This study suggests that regular exercise in excess of 200 min week is associated with greater medium-term weight loss following laparoscopic bariatric surgery. Multidisciplinary bariatric surgery teams should consider emphasizing exercise at this level to help patients achieve optimal weight loss.

Introduction: To analyze the molecular pathogenesis of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), a small animal model such as mice is needed: human angiotensin converting enzyme 2 (hACE2), the receptor of SARS-CoV-2, needs to be expressed in the respiratory tract of mice.

Methods: We conferred SARS-CoV-2 susceptibility in mice by using an adenoviral vector expressing hACE2 driven by an elongation factor 1α (EF1α) promoter with a leftward orientation.

Results: In this model, severe pneumonia like human COVID-19 was observed in SARS-CoV-2-infected mice, which was confirmed by dramatic infiltration of inflammatory cells in the lung with efficient viral replication.

Surprise Baby: Abdominoplasty Performed During Unknown Pregnancy.

Plast Reconstr Surg Glob Open

December 2024

From the Department of Plastic, Aesthetic and Reconstructive Surgery, Hospital of the Brothers of St. John of God, Paracelsus Medical University, Salzburg, Austria.

Abdominoplasty is a commonly performed procedure for patients after significant weight loss and in postpregnancy women. Stable weight and completed family planning are critical for optimal outcomes, as pregnancy postabdominoplasty can increase risks for both mother and fetus and potentially compromise aesthetic results. We present the first reported case of a patient undergoing abdominoplasty while unknowingly pregnant.

Background: Processing methods of traditional Chinese medicinal materials are critical in influencing the active metabolites and pharmacological effects. The fresh processing method effectively prevents the loss and degradation of metabolites, common in traditional drying and softening processes, while also reducing production costs. (AR), a leguminous botanical drug, is widely utilized in clinical practice and functional foods.

Maturity-onset diabetes of the young (MODY) represents 1% to 5% of patients with diabetes mellitus (DM), and numerous genes associated with MODY have been identified. While mutations of the insulin gene () are known to cause permanent neonatal DM, rare disease-causing variants have also been found in MODY. These patients demonstrate variable clinical phenotypes-from milder forms requiring lifestyle or oral agent interventions to severe forms requiring lifelong insulin.
