Nasopharyngeal swabs have historically been considered the preferred specimen type for the detection of respiratory viruses, including SARS-CoV-2. However, in response to a global pandemic with shortages of swabs and specimen transport media, limited access to qualified health care personnel, and needs for large-scale testing in nonmedical settings, alternative sample types have been validated for COVID-19 diagnosis. The purpose of this review is to highlight the diagnostic accuracy and clinical utility of non-nasopharyngeal respiratory samples for SARS-CoV-2 molecular diagnostic testing.

Background: Of the numerous complications encountered by people with diabetes (PWD), the effect on mental health is concerning. Within mental health, diabetes distress (DD) occurs when a patient has unfavourable emotional stress while managing their condition, which can be managed by coping strategies but are less studied together in Indian settings. So, the present study aimed to determine the proportion of DD and associated factors and coping skills among the PWD.

Objective: Understanding healthcare-seeking propensity is crucial for optimizing healthcare utilization, especially for patients with chronic conditions like hypertension or diabetes, given their substantial burden on healthcare systems globally. This study aims to evaluate hypertensive or diabetic patients' healthcare-seeking propensity based on the severity of symptoms, categorizing symptoms as either major or minor. It also explores factors influencing healthcare-seeking propensity and examines whether healthcare-seeking propensity affects healthcare utilization and preventable hospitalizations.

The characteristics of data produced by omics technologies are pivotal, as they critically influence the feasibility and effectiveness of computational methods applied in downstream analyses, such as data harmonization and differential abundance analyses. Furthermore, variability in these data characteristics across datasets plays a crucial role, leading to diverging outcomes in benchmarking studies, which are essential for guiding the selection of appropriate analysis methods in all omics fields. Additionally, downstream analysis tools are often developed and applied within specific omics communities due to the presumed differences in data characteristics attributed to each omics technology.

To investigate the clinicopathological features, diagnosis, genetic alterations, and biological behaviors of hamartomatous inverted hyperplastic polyp (HIHP) in the gastrointestinal tract. The clinical, sonographic, endoscopic and pathologic data of 10 HIHP cases diagnosed at the First Affiliated Hospital of Air Force Medical University, Xi'an, China from January 2013 to March 2024 were collected. Their clinicopathological features and histological morphology were analyzed.

Background: Earlier evidence indicated that metabolic and bariatric surgery (MBS) may adversely affect neonatal outcomes among patients conceiving soon after MBS, but recent studies demonstrated conflicting results, especially for new surgical techniques.
Objectives: The aim of this study was to assess the effects of MBS types and surgery to birth interval on maternal, birth, and nonbirth outcomes in women with severe obesity.
Setting: New York State's all-payer hospital discharge database (2008-2019).
