The impact of exercise perceptions and depressive symptoms on polycystic ovary syndrome-specific health-related quality of life.

Background: Studies indicate that women with polycystic ovary syndrome have high depressive symptom scores and more perceived barriers than benefits to exercise, factors that may affect health-related quality-of-life. The purpose of this cross-sectional study was to explore the impact of perceived exercise benefits and barriers, exercise outcome expectations, and depressive symptoms on polycystic ovary syndrome-specific health-related quality-of-life.

Methods: A survey link was posted on polycystic ovary syndrome Facebook groups.

Characterization of the High-Affinity Fuzzy Complex between the Disordered Domain of the E7 Oncoprotein from High-Risk HPV and the TAZ2 Domain of CBP.

The intrinsically disordered N-terminal region of the E7 protein from high-risk human papillomavirus (HPV) strains is responsible for oncogenic transformation of host cells through its interaction with a number of cellular factors, including the TAZ2 domain of the transcriptional coactivator CREB-binding protein. Using a variety of spectroscopic and biochemical tools, we find that despite its nanomolar affinity, the HPV16 E7 complex with TAZ2 is disordered and highly dynamic. The disordered domain of HPV16 E7 protein does not adopt a single conformation on the surface of TAZ2 but engages promiscuously with its target through multiple interactions involving two conserved motifs, termed CR1 and CR2, that occupy an extensive binding surface on TAZ2.

Stability of health-related quality of life and morbidity burden from 18 months after diagnosis of prostate cancer: results of a UK-wide population-based outcome cohort.

Objective: To evaluate the dynamic nature of self-reported health-related quality of life (HRQL) and morbidity burden in men diagnosed with prostate cancer, we performed a follow-up study of the Life After Prostate Cancer Diagnosis (LAPCD) study cohort 12 months after initial survey.

Methods: The LAPCD study collected information from 35,823 men across the UK who were 18-42 months post-diagnosis of prostate cancer. Men who were still alive 12 months later were resurveyed.

Association of the COVID-19 outbreak with acute stroke care in Switzerland.

Background And Purpose: In Switzerland, the COVID-19 incidence during the first pandemic wave was high. Our aim was to assess the association of the outbreak with acute stroke care in Switzerland in spring 2020.

Methods: This was a retrospective analysis based on the Swiss Stroke Registry, which includes consecutive patients with acute cerebrovascular events admitted to Swiss Stroke Units and Stroke Centers.

Viral Transduction of Human Rod Opsin or Channelrhodopsin Variants to Mouse ON Bipolar Cells Does Not Impact Retinal Anatomy or Cause Measurable Death in the Targeted Cells.

The viral gene delivery of optogenetic actuators to the surviving inner retina has been proposed as a strategy for restoring vision in advanced retinal degeneration. We investigated the safety of ectopic expression of human rod opsin (hRHO), and two channelrhodopsins (enhanced sensitivity CoChR-3M and red-shifted ReaChR) by viral gene delivery in ON bipolar cells of the mouse retina. Adult mice were bred to be retinally degenerate or non-retinally degenerate (homozygous and heterozygous for the mutation, respectively) and intravitreally injected with recombinant adeno-associated virus AAV2/2(quad Y-F) serotype containing a double-floxed inverted transgene comprising one of the opsins of interest under a CMV promoter.

Serum from Older Adults Increases Apoptosis and Molecular Aging Markers in Human Hippocampal Progenitor Cells.

Age-related alteration in neural stem cell function is linked to neurodegenerative conditions and cognitive decline. In rodents, this can be reversed by exposure to a young systemic milieu and conversely, the old milieu can inhibit stem cell function in young rodents. In this study, we investigated the effect of the human systemic milieu on human hippocampal progenitor cells (HPCs) using human serum from early adulthood, mid-life and older age.

Developing Community-Based Palliative Care Services for People Living with HIV in Africa.

Africa continues to be disproportionately affected by HIV/AIDS. Poor access to medical care, limited access to antiretroviral drugs, and lack of supportive care for persons who are symptomatic lead to disease progression. Community-based palliative care services are effective in providing supportive services throughout the course of the illness, but palliative care services are limited in Africa.

Assessing the impact of a gynaecomastia assessment and treatment infographic in primary care in Greater Manchester.

Introduction: Men with gynaecomastia are routinely referred to breast clinics, yet most do not require breast surgical intervention. The aim of this study was to assess the impact of a novel point-of-care gynaecomastia decision infographic in primary care on the assessment, management and referral practices to tertiary breast surgical services.

Methods: A study was carried out of male patient referrals from primary care in Greater Manchester to a tertiary breast centre between January and March in 2018-2020.

Monoclonal antibody treatment for COVID-19 in solid organ transplant recipients.

Solid organ transplant (SOT) recipients are at high risk for severe coronavirus disease 2019 (COVID-19). Studies suggest that early intervention with monoclonal antibody (MAB) treatment directed against the SARS-CoV-2 spike protein may reduce the risk of emergency department visits or hospitalization for COVID-19, especially in high-risk patients. Herein, we describe our single-center experience of 93 SOT (50 kidney, 17 liver, 11 lung, nine heart, and six dual-organ) recipients with mild to moderate COVID-19 who were treated with bamlanivimab or casirivimab-imdevimab per emergency use authorization guidelines.

Does Obesity Affect Preoperative Shoulder Balance in Adolescent Idiopathic Scoliosis?

Background: Obese patients with adolescent idiopathic scoliosis (AIS) have been shown to present with larger curve magnitudes preoperatively. However, the effect of obesity on shoulder balance in AIS remains unknown. The purpose of our study was to determine if overweight and obese patients with AIS have worse radiographic shoulder balance on initial presentation when compared with normal weight patients.

Afrocentric screening program for breast, colorectal, and cervical cancer among immigrant patients in Ontario.

Problem Addressed: Black and immigrant populations across Canada have lower screening rates than Canadian-born white populations, predisposing them to increased cancer morbidity and mortality. Effective interventions are required to increase cancer screening rates among these populations.

Objective Of Program: To improve breast, colorectal, and cervical cancer screening rates at TAIBU Community Health Centre, which has a mandate to provide primary health care services to the Black and immigrant community in the greater Toronto area.

Long-term outcome of biologically guided dose-escalated radiotherapy of localized prostate cancer.

Background: Biologically created subvolumes enable non-uniform dose distributions in prostate cancer radiotherapy (RT) thus potentially improving therapeutic ratio and reducing toxicity. We present the long-term outcome of men receiving focal boosting of carbon-11 acetate (ACE) PET-CT metabolically active areas in prostate carcinoma.

Material And Methods: Thirty men with hormone naïve localized prostate carcinoma underwent ACE PET/CT for RT planning.

A model of uniaxial implant seating by impaction.

Implants anchored by press-fit are predominantly implanted by impaction. This method allows sufficiently high forces to be generated easily by the surgeon. Suitable impaction should provide adequate implant seating without damaging the patient (tissues), the implant and implantation system, or the surgeon.

Home-based Extended Rehabilitation for Older people (HERO): study protocol for an individually randomised controlled multi-centre trial to determine the clinical and cost-effectiveness of a home-based exercise intervention for older people with frailty as extended rehabilitation following acute illness or injury, including embedded process evaluation.

Background: The majority of older people (> 65 years) in hospital have frailty and are at increased risk of readmission or death following discharge home. In the UK, following acute hospitalisation, around one third of older people with frailty are referred on for rehabilitation, termed 'intermediate care' services. Although this rehabilitation can reduce early readmission to hospital (< 30 days), recipients often do not feel ready to leave the service on discharge, suggesting possible incomplete recovery.

Boosting of Cross-Reactive Antibodies to Endemic Coronaviruses by SARS-CoV-2 Infection but not Vaccination with Stabilized Spike.

Pre-existing antibodies to endemic coronaviruses (CoV) that cross-react with SARS-CoV-2 have the potential to influence the antibody response to COVID-19 vaccination and infection for better or worse. In this observational study of mucosal and systemic humoral immunity in acutely infected, convalescent, and vaccinated subjects, we tested for cross reactivity against endemic CoV spike (S) protein at subdomain resolution. Elevated responses, particularly to the β-CoV OC43, were observed in all natural infection cohorts tested and were correlated with the response to SARS-CoV-2.

Voice-Activated Virtual Home Assistant Use and Social Isolation and Loneliness Among Older Adults: Mini Review.

A lack of social connectedness is common among older adults due to living alone, loss of loved ones, reduced mobility, and, more recently, social distancing created by the global Covid-19 pandemic. Older adults are vulnerable to social isolation and loneliness, which pose significant health risks comparable to those of smoking, obesity, physical inactivity, and high blood pressure. A lack of social connectedness is also correlated with higher mortality rates even when controlling for other factors such as age and comorbid conditions.

PD-1 expression in hepatocellular carcinoma predicts liver-directed therapy response and bridge-to-transplant survival.

Background: Hepatocellular carcinoma (HCC) patients undergo liver-directed therapy (LDT) to control tumor burden while awaiting liver transplantation with response impacting waitlist survival. In this study, we investigate the link between absolute lymphocyte count (ALC) and PD-1 expression with response to LDT and bridge-to-transplant survival.

Methods: Treatment-naïve HCC patients (n = 86) undergoing LDT were enrolled at a single center from August 2016-March 2020.

"Pilot" spectator events in British horseracing during COVID-19: post-event SMS COVID-19 reporting.

This study aimed to assess (i) COVID-19 transmission prior to and following spectator events and (ii) methodological approaches to capturing event-related transmission during the spectator return. Local authority population transmission rates were used to identify higher transmission areas, which were excluded from participant attendance following registration. Using observational online and SMS questionnaires, self-reported COVID-19 diagnoses (positive tests) and racing-related NHS Test and Trace contacts within 14 days of spectating were reported for two British Horseracing events and three Point to Point (PTP) grassroots races.

Cyclical experience-based design: A proposal for engaging stakeholders in a co-creative model for primary health care service design.

Healthcare services face difficulties in using structured methods for service design and having patient participation in such processes. There are few models on healthcare service design and even less focused on Primary Health Care (PHC) in the literature. Therefore, this paper contributes to this domain by presenting the proposal of a co-creative model to design PHC services.

The mannose receptor (CD206) identifies a population of colonic macrophages in health and inflammatory bowel disease.

To understand the contribution of mononuclear phagocytes (MNP), which include monocyte-derived intestinal macrophages, to the pathogenesis of inflammatory bowel disease (IBD), it is necessary to identify functionally-different MNP populations. We aimed to characterise intestinal macrophage populations in patients with IBD. We developed 12-parameter flow cytometry protocols to identify and human intestinal MNPs.
