Counting Limb Length Ratios in Roux-en-Y Gastric Bypass: A Demonstration of Safety and Feasibility Using a 25-Patient Case Series in a High-Volume Academic Center.

Despite being one of the most performed bariatric procedures, there is no consensus regarding optimal limb lengths for Roux-en-Y gastric bypass (RYGB), which may impact weight loss and obesity-related comorbidity resolution. We hypothesize that a ratio-adjusted small bowel to Roux and BP limb lengths in RYGB results in superior outcomes. This study aims to define total intestinal length (TIL) and the feasibility of its intraoperative measurement during RYGB.

The ecology of the oxyscape in coastal ecosystems.

Oxygen is vital for marine life. Despite global ocean deoxygenation, coastal oxygen dynamics are poorly understood. We synthesise the biological and mechanical processes that shape the coastal oxyscape and how organisms respond to it.

Trends and Outcomes of Metabolic Surgery in Adolescents with BMI ≥ 50 vs < 50 kg/m: A Retrospective Study Using the MBSAQIP Database.

Background: Metabolic and bariatric surgery (MBS) is an effective and increasingly utilized treatment for adolescents with severe obesity, particularly those with BMI ≥ 50 kg/m. However, data on safety and outcomes in this high-risk group remains limited.

Methods: We conducted a retrospective analysis of the MBSAQIP database from 2020-2023, identifying adolescents aged 13-18 years who underwent primary sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB).

Growth rates and response to nutrient variability in the green tide forming alga Ulva stenophylloides from Algarrobo Bay, Chile.

Blooms of green macroalgae have become a recurring phenomenon along many shores. Here, we conducted oceanographic surveys and field experiments to quantify daily growth rates of Ulva stenophylloides, the predominant species in the green tides that occur year-round at the southern end of the wave-protected open bay of Algarrobo, central Chile. We assessed the association between growth and nutrient availability, as well as other environmental variables, and compared growth rates between the south end of the bay and the north end (1.

Long-term outcomes of laparoscopic duodenojejunostomy for superior mesenteric artery syndrome.

Introduction: Superior mesenteric artery syndrome (SMAS) is caused by partial obstruction of the duodenum between the SMA and the aorta. While laparoscopic duodenojejunostomy (DJ) shows favorable short- and intermediate-term outcomes, characterization of long-term outcomes remains limited.

Methods And Procedures: An IRB-approved retrospective study was conducted on patients who underwent laparoscopic DJ from January 2007 to January 2023 at our center.
