Background: There is a lack of adequate prospective data on quality-of-life (QOL) and its predictors in patients undergoing laparoscopic sleeve gastrectomy (LSG). The aim of this study was to assess longitudinal changes in QOL after LSG with the use of the obesity-specific Moorehead-Ardelt II questionnaire (MAII) and to identify clinical parameters associated with QOL outcome.
Methods: Morbidly obese patients consecutively admitted for LSG, over a 30-month period, were prospectively studied. QOL was assessed using the validated Greek version of the MAII questionnaire and a visual analogueue scale (VAS), preoperatively and at 6, 12, and 24 months postoperatively. Anthropometric data and obesity-related co-morbidities were recorded.
Results: A total of 111 patients with a mean age 36.8±9.2 years were included. Mean preoperative body mass index (BMI) was 49.1±7.5 kg/m2. Percentage excess BMI loss (%EBL) was 51.1±14.9, 64.2±17.9 and 66.4±18.0 at 6, 12, and 24 months, respectively. Postoperatively, all obesity-related co-morbidities were significantly improved. MAII score increased from -.40±1.30 preoperatively to 1.75±.83, 2.18±.80, and 1.95±.71 at 6, 12, and 24 months postoperatively (trend P<.001). Preoperative median (interquartile range) VAS was 3 (1) increasing to 9 (2), 10 (1), and 9 (1) at 6, 12, and 24 months postoperatively (P<.001). %EBL and reduction in obesity-related co-morbidities, especially resolution of diabetes and sleep apnea, correlated significantly with higher QOL during the course of the study.
Conclusion: LSG, a safe and effective bariatric operation, results in sustained weight loss and significant improvements in QOL. Both weight loss and amelioration of co-morbidities contribute to higher level of postsurgical QOL.

Outcomes following resective and disconnective strategies in the treatment of epileptic spasms: a systematic review of the literature and individual patient data meta-analysis.

Epileptic spasms (ES) are a unique seizure type typically presenting in the form of infantile epileptic spasms syndrome (IESS) with characteristic hypsarrhythmia on scalp EEG and a preponderance with developmental delay or regression. While pharmacotherapy is the mainstay of treatment, surgical options, including disconnective or resective procedures, are increasingly recognized as viable therapeutic options for recurrent or persistent ES. However, limited data on safety, effectiveness, and prognostic factors hinder informed decision-making regarding surgery indications, timing, and intervention type.

Objective: Extant imaging methods used for the proper identification of the parathyroid glands to prevent post-operative hypothyroidism associated with the resection of differentiated thyroid cancer (DTC) are limited by factors such as low specificity, high cost, and technical complexity. This study, therefore, sought to investigate the efficacy of the immunocolloidal gold strip method combined with nanocarbon negative imaging tracing technology for parathyroid gland imaging during radical resection of DTC in elderly patients.
Methods: A total of 100 elderly patients with DTC were enrolled and randomly divided into two groups: the control group and the observation group.
