Pharmacists' practices and views regarding management of sexual health in patients with cancer.

Introduction: Sexual health issues associated with cancer can significantly impact patients' psychosocial well-being and overall quality of life. These issues are frequently medication-related, placing pharmacists in an opportune position to manage sexual health concerns in patients with cancer. Currently, no literature exists exploring pharmacists' practices related to the management of sexual health in oncology patients.

Effect of common maintenance drugs on the risk and severity of COVID-19 in elderly patients.

Background: Maintenance drugs are used to treat chronic conditions. Several classes of maintenance drugs have attracted attention because of their potential to affect susceptibility to and severity of COVID-19.

Methods: Using claims data on 20% random sample of Part D Medicare enrollees from April to December 2020, we identified patients diagnosed with COVID-19.

Follow-up after post-partum psychiatric emergency department visits: an equity-focused population-based study in Canada.

Background: Emergency department visits for a psychiatric reason in the post-partum period represent an acute need for mental health care at a crucial time, but little is known about the extent of timely outpatient follow-up after these visits or how individual and intersecting social determinants of health influence this outcome. This study aimed to examine outpatient mental health care follow-up by a physician in the 30 days after an individual attended the emergency department for a psychiatric reason in the post-partum period and understand how social determinants of health affect who receives follow-up care.

Methods: In this population-based cohort study, routinely collected health data from Ontario, Canada were accessed through ICES to identify all post-partum individuals whose sex was listed as female on their health card and who had attended an emergency department in Ontario before the COVID-19 pandemic for a psychiatric reason.

Antigen-Antibody Complex-Guided Exploration of the Hotspots Conferring the Immune-Escaping Ability of the SARS-CoV-2 RBD.

The COVID-19 pandemic resulting from the spread of SARS-CoV-2 spurred devastating health and economic crises around the world. Neutralizing antibodies and licensed vaccines were developed to combat COVID-19, but progress was slow. In addition, variants of the receptor-binding domain (RBD) of the spike protein confer resistance of SARS-CoV-2 to neutralizing antibodies, nullifying the possibility of human immunity.

The Discrepancy Between Standard Histologic WHO Grading of Meningioma and Molecular Profile: A Single Institution Series.

Introduction: Meningiomas are the most common primary central nervous system (CNS) tumor. They are most often benign, but a subset of these can behave aggressively. Current World Health Organization (WHO) guidelines classify meningiomas into three grades based on the histologic findings and presence or absence of brain invasion.

Case series of HIV SARS-CoV-2 co-infection in Chinese adults.

Objectives: Little is known whether differences exist in virus shedding, immune and inflammatory response related to SARS-CoV-2 in people living with human immunodeficiency virus (PLWH). We assessed viral RNA and cytokine profiles of HIV and SARS-CoV-2 coinfection in Hong Kong.

Methods: PLWH hospitalized with SARS-CoV-2 infection in Hong Kong were included, compared with age-matched and disease severity-matched SARS-CoV-2 infected controls (ratio of 1:5) from February 1st 2020 to July 31st 2020.

A Systematic Quality Scoring Analysis to Assess Automated Cardiovascular Magnetic Resonance Segmentation Algorithms.

Background: The quantitative measures used to assess the performance of automated methods often do not reflect the clinical acceptability of contouring. A quality-based assessment of automated cardiac magnetic resonance (CMR) segmentation more relevant to clinical practice is therefore needed.

Objective: We propose a new method for assessing the quality of machine learning (ML) outputs.

The Impact of Surgical Resectability on Outcomes for Patients Undergoing Primary Radiation Treatment for Human Papillomavirus-Related Oropharyngeal Cancer.

Purpose: Primary radiation therapy with or without chemotherapy (RT/CRT) is the most common treatment for oropharyngeal squamous cell carcinomas (OPSCC), but there has been an increase in transoral surgery (TOS) for T1-2 tumors. Because only a subset of T1-2 tumors are TOS-favorable, nonrandomized comparisons between RT/CRT and TOS could be confounded by indication. We aimed to compare outcomes of potential TOS-candidates versus non-TOS candidates, among patients who underwent RT/CRT for early T-stage OPSCC.

Transoral robotic surgery for the identification of unknown primary head and neck squamous cell carcinomas: Its effect on the wait and the weight.

Background: Neck carcinoma of unknown primary (CUP) is a frequent scenario. Transoral robotic mucosectomies (TORM) of pharynx have increased rate of primary identification, but come with cost of treatment delay.

Methods: We reviewed patients who underwent CUP protocol from 2014 to 2020.

Introduction and expression of PIK3CA in a papillary thyroid cancer BRAF cell line leads to a dedifferentiated aggressive phenotype.

Anaplastic thyroid cancer (ATC) is a rare, aggressive form of undifferentiated thyroid cancer, which exhibits rapid progression and is almost universally fatal. At least a subset of ATC is thought to arise from pre-existing well-differentiated thyroid cancer, most frequently papillary thyroid cancer (PTC). While PIK3CA mutations are rare in PTC, they are common in ATC and tend to co-occur with BRAF mutations.

Tumor molecular differences associated with outcome disparities of Black patients with head and neck cancer.

Background: Numerous studies of head and neck squamous cell carcinoma (HNSCC) have demonstrated disparate outcomes by race and ethnicity. Beyond known associations with socioeconomic variables, whether these are also associated with differences in tumor molecular composition has thus far been poorly explored.

Methods: We downloaded clinical and multiplatform molecular data from The Cancer Genome Atlas and other published studies.

Postoperative Respiratory Failure After Elective Abdominal Surgery: A Case-Control Study.

Introduction: Postoperative respiratory failure (PRF) contributes significantly to morbidity and mortality. We sought to identify patient characteristics and perioperative risk factors associated with PRF in patients undergoing elective abdominal surgery to improve patient outcomes.

Methods: We retrospectively reviewed patients undergoing elective abdominal surgery from 2011 to 2016 at our institution.

Circular RNA ANAPC7 Inhibits Tumor Growth and Muscle Wasting via PHLPP2-AKT-TGF-β Signaling Axis in Pancreatic Cancer.

Background & Aims: Pancreatic cancer has the highest prevalence of cancer-associated cachexia among all cancers. ZIP4 promotes pancreatic cancer progression by regulating oncogenic miR-373, and perturbation of circular RNAs (circRNAs) is associated with cancer aggressiveness. This study aimed to identify circRNAs involved in ZIP4/miR-373-driven cancer growth and cachexia and decipher the underlying mechanism.

Association of Antihypertensives and Cognitive Impairment in Long-Term Care Residents.

Background: Certain classes of antihypertensive medication may have different associations with cognitive impairment.

Objective: To examine the association between prevalent use of antihypertensive medications that stimulate (thiazides, dihydropyridine calcium channel blockers, angiotensin type I receptor blockers) versus inhibit (angiotensin-converting enzyme inhibitors, beta-blockers, non-dihydropyridine calcium channel blockers) type 2 and 4 angiotensin II receptors on cognitive impairment among older adults residing in Veterans Affairs (VA) nursing homes for long-term care.

Methods: Retrospective cohort study.

COVID-19 Mental Health Stressors of Health Care Providers in the Pandemic Acceptance and Commitment to Empowerment Response (PACER) Intervention: Qualitative Study.

Background: Since the pandemic, more Canadians have reported poorer mental health. A vital group experiencing a high level of stressors consists of health care providers (HCPs) caring for COVID-19 patients, carrying out public health responses, or working with vulnerable populations. The mental health of HCPs is negatively affected by the pandemic, not only at work but also at home and in the community.

Perturbation of Wnt/β-catenin signaling and sexual dimorphism in non-alcoholic fatty liver disease.

Aims: The prevalence of non-alcoholic fatty liver disease (NAFLD) and its progression to non-alcoholic steatohepatitis (NASH) is higher in postmenopausal women than men. The aim of this study was to determine the molecular mechanisms underlying this sexual dimorphism in NAFLD.

Methods: A total of 24 frozen liver samples of both sexes (normal and NAFLD/NASH) were used in this study.

Computer-aided Veress needle guidance using endoscopic optical coherence tomography and convolutional neural networks.

During laparoscopic surgery, the Veress needle is commonly used in pneumoperitoneum establishment. Precise placement of the Veress needle is still a challenge for the surgeon. In this study, a computer-aided endoscopic optical coherence tomography (OCT) system was developed to effectively and safely guide Veress needle insertion.

Using Fourier ptychography microscopy to achieve high-resolution chromosome imaging: an initial evaluation.

Significance: Searching analyzable metaphase chromosomes is a critical step for the diagnosis and treatment of leukemia patients, and the searching efficiency is limited by the difficulty that the conventional microscopic systems have in simultaneously achieving high resolution and a large field of view (FOV). However, this challenge can be addressed by Fourier ptychography microscopy (FPM) technology.

Aim: The purpose of this study is to investigate the feasibility of utilizing FPM to reconstruct high-resolution chromosome images.

Effects of Acceptance and Commitment Therapy (ACT) on Mental Health and Resiliency of Migrant Live-in Caregivers in Canada: Pilot Randomized Wait List Controlled Trial.

Background: Temporary migrant live-in caregivers constitute a vulnerable stream of temporary foreign workers in Canada. This is because the majority are racialized women from the Global South, the gendered nature of caregiving work has historically been undervalued, and their working and living spheres are intertwined which makes application of labor laws and surveillance almost impossible. Their invisible position in the fabric of Canadian society along with their precarious employment and immigration status place their mental health at jeopardy.

Gut microbial trimethylamine is elevated in alcohol-associated hepatitis and contributes to ethanol-induced liver injury in mice.

There is mounting evidence that microbes residing in the human intestine contribute to diverse alcohol-associated liver diseases (ALD) including the most deadly form known as alcohol-associated hepatitis (AH). However, mechanisms by which gut microbes synergize with excessive alcohol intake to promote liver injury are poorly understood. Furthermore, whether drugs that selectively target gut microbial metabolism can improve ALD has never been tested.

Gut microbe-targeted choline trimethylamine lyase inhibition improves obesity via rewiring of host circadian rhythms.

Obesity has repeatedly been linked to reorganization of the gut microbiome, yet to this point obesity therapeutics have been targeted exclusively toward the human host. Here, we show that gut microbe-targeted inhibition of the trimethylamine N-oxide (TMAO) pathway protects mice against the metabolic disturbances associated with diet-induced obesity (DIO) or leptin deficiency (). Small molecule inhibition of the gut microbial enzyme choline TMA-lyase (CutC) does not reduce food intake but is instead associated with alterations in the gut microbiome, improvement in glucose tolerance, and enhanced energy expenditure.

Magnetic nanoribbons with embedded cobalt grown inside single-walled carbon nanotubes.

Molecular magnetism and specifically magnetic molecules have recently gained plenty of attention as key elements for quantum technologies, information processing, and spintronics. Transition to the nanoscale and implementation of ordered structures with defined parameters is crucial for advanced applications. Single-walled carbon nanotubes (SWCNTs) provide natural one-dimensional confinement that can be implemented for encapsulation, nanosynthesis, and polymerization of molecules into nanoribbons.

More than Mental Illness: Experiences of Associating with Stigma of Mental Illness for Chinese College Students.

From existing empirical research, we identified that Chinese college students commonly experience stigma surrounding mental illness and found some factors that support them in resisting the stigma and achieving psychological health. However, less research provides qualitative data involving individual experiences and insights on mental illness within this group of college students. This study, based on Linking Hearts (an internationally cooperative research-sharing project between China and Canada), was conducted in Shandong, Jinan, and aims to promote the mental health of college students by empowering interdisciplinary professionals and students.
