Objectives:
The coronavirus disease 2019 pandemic led to various intensities of lockdowns, affecting lifestyles globally. This study investigates the impact of partial lockdown versus total lockdown on adult physical activity (PA) and sedentary behavior.
Methods:
A cross-sectional online survey was conducted from April 2020 to October 2020, with 493 participants included in the analysis.
Results:
The analysis revealed no significant differences in total PA or total sitting time between partial lockdown and total lockdown scenarios. However, moderate physical activity (MPA) significantly decreased during total lockdowns, with more pronounced reductions among females than males. Notably, a positive correlation was found between household area and MPA, suggesting that larger living spaces may encourage more PA. A negative correlation was observed between sitting time and MPA during both types of lockdown.
Conclusions
Total lockdown conditions were associated with a significant decrease in MPA, highlighting sex disparities in PA responses. Living space size emerged as a crucial factor in maintaining PA levels during restricted conditions. This study emphasizes the need to consider environmental and demographic factors in public health strategies during prolonged periods of restricted movement.

Pyloric dysfunction is defined as hypertonia or spasm of the pyloric sphincter. The pylorus plays a key role in gastric emptying, but its function remains incompletely understood. Most studies have focused on gastroparesis regardless of the underlying pathophysiology. Few studies have reported pyloric dysfunction in patients with gastroparesis, and the diagnostic and treatment modalities for pyloric dysfunction are not well established. Recently developed diagnostic modalities assessing pyloric function, such as high-resolution antroduodenal manometry and endoluminal functional lumen imaging, are currently being evaluated. A variety of therapeutic interventions targeting the pylorus, including pharmacologic agents, intrapyloric botulinum injection, endoscopic balloon dilation, stent insertion, surgical pyloroplasty, and gastric peroral endoscopic pyloromyotomy, have been proposed. Among these, gastric peroral endoscopic pyloromyotomy has emerged as a novel, minimally invasive therapy with demonstrated efficacy and safety for refractory gastroparesis. This article reviews the pathophysiology of pyloric dysfunction and the potential diagnostic and therapeutic modalities based on the latest literature.

Endoscopic bariatric therapies (EBTs) are minimally invasive and safe procedures with favorable weight loss outcomes in obesity treatment. We aimed to present the weight loss mechanism of action of EBTs and an individualized selection method for patients with obesity. We searched PubMed, Medline, Scopus, Embase, and Google Scholar databases for studies on the topic from databases inception to July 1, 2023, written in English. We focused on EBTs potential mechanism of action to induce weight loss. We also present an expert opinion on a novel selection of EBTs based on their mechanism of action. EBTs can result in weight loss through variable mechanisms of action. They can induce earlier satiation, delay gastric emptying, restrict the accommodative response of the stomach, decrease caloric absorption, and alter the secretion of gastrointestinal hormones. Selecting EBTs may be guided through their mechanism of action by which patients with abnormal satiation may benefit more from tissue apposition devices and aspiration therapy while patients with fast gastric emptying may be better candidates for intragastric devices, endoscopic anastomosis devices, and duodenal mucosal resurfacing. Consequently, the selection of EBTs should be guided by the mechanism of action which is specific to each type of therapy.

Krukenberg tumors are very rare. Its origin is difficult to define especially if its gross features mimic a primary ovarian cancer. We present a case of a 24-year-old Filipino female patient with metastatic mucinous ovarian adenocarcinoma of colonic origin that mimicked primary ovarian cancer and genitourinary tuberculosis. Surgery was done and histopathology revealed that the cancer was a metastatic mucinous adenocarcinoma of colonic origin. This case highlights the importance of differentiating between benign and malignant ovarian lesions as well as distinction between primary and metastatic ovarian neoplasms. Radiological imaging has an evolving role in diagnosis of different cancers, which may be improved through better clinical correlation and developing meaningful differential diagnosis while advancing to a more strategized algorithm in the diagnostic approach.
