The impact of an interactive online informational and peer support application (app) for patients with low anterior resection syndrome (LARS) on quality of life: a multicenter randomized controlled trial.

Introduction: Low Anterior Resection Syndrome (LARS) describes bowel dysfunction post-restorative proctectomy (RP) and is associated with poor quality of life (QoL). The aim of this study was to assess the impact of an interactive online informational and peer support App on participants' QoL (primary outcome), LARS, and emotional distress (secondary outcomes).

Methods: A multicentre, randomized, parallel-group trial was conducted across five Canadian colorectal surgery practices.

A Possible Protective Effect of IgA Against Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) in Bronchoalveolar Lavage in COVID-19 Patients Admitted to Intensive Care Unit.

SARS-CoV-2 infection induces a humoral immune response, producing virus-specific antibodies such as IgM, IgG, and IgA. IgA antibodies are present at mucosal sites, protecting against respiratory and other mucosal infections, including SARS-CoV-2, by neutralizing viruses or impeding attachment to epithelial cells. Since SARS-CoV-2 spreads through the nasopharynx, the specific IgAs of SARS-CoV-2 are produced quickly after infection, effectively contributing to virus neutralization.

Food and Housing Insecurity, COVID-19 Pandemic Effects on Health-Related Activities, and Care Plans for Children with Obesity.

Objective: To understand the association between food insecurity (FI) and housing insecurity (HI) risk, the effects of the COVID-19 pandemic on health-related activities among children with overweight or obesity, and caregivers' and clinicians' challenges and priorities related to pediatric weight management.

Methods: We conducted surveys with caregivers of children with overweight and obesity and pediatric clinicians at two academic medical centers in the Greater Boston area. We used multivariable logistic regression models to examine associations between FI and HI risk and the effects of the COVID-19 pandemic on health-related activities and descriptive statistics to summarize caregivers' and clinicians' challenges and priorities related to pediatric weight management.

Concordance of Whole-Slide Imaging and Conventional Light Microscopy for Assessment of Pathologic Response Following Neoadjuvant Therapy for Lung Cancer.

Pathologic response is an endpoint in many ongoing clinical trials for neoadjuvant regimens, including immune checkpoint blockade and chemotherapy. Whole-slide scanning of glass slides generates high-resolution digital images and allows for remote review and potential measurement with image analysis tools, but concordance of pathologic response assessment on digital scans compared with that on glass slides has yet to be evaluated. Such a validation goes beyond previous concordance studies, which focused on establishing surgical pathology diagnoses, as it requires quantitative assessment of tumor, necrosis, and regression.
