Peroxiredoxin 2 mediates redox-stimulated adaptations to oxidative phosphorylation induced by contractile activity in human skeletal muscle myotubes.

Skeletal muscle generates superoxide during contractions, which is converted to hydrogen peroxide (HO). HO has been proposed to activate signalling pathways and transcription factors that regulate adaptive responses to exercise, but the concentration required to oxidize and activate key redox-sensitive signalling proteins in vitro is much higher than the typical intracellular levels seen in muscle after exercise. We hypothesized that 2-Cys-peroxiredoxins (PRDX), which rapidly oxidize in the presence of physiological concentrations of HO, serve as intermediary signalling molecules and play a crucial role in activating adaptive pathways following muscle contractions.

Chronic pain at 1-year following knee arthroplasty is associated with a worse joint-specific function and health-related quality of life.

Purpose: The purpose of this study was to identify independent variables associated with chronic pain (CP) at 1 year following knee arthroplasty (KA) and whether this influenced functional outcomes.

Methods: This retrospective study was conducted over a 2-year period and included 2588 patients with completed Oxford knee score (OKS) and EuroQol (EQ)-five domains (5D) preoperatively and at 1 and 2 years postoperatively. The OKS pain component score was used to define patients with CP (≤14 points).

Improving quality in adult long covid services: Findings from the LOCOMOTION quality improvement collaborative.

The protracted form of COVID-19 known as 'long covid' was first described in 2020. Its symptoms, course and prognosis vary widely; some patients have a multi-system, disabling and prolonged illness. In 2021, ring-fenced funding was provided to establish 90 long covid clinics in England; some clinics were also established in Scotland and Wales.

Cancer health awareness through screening and education: A community approach to healthy equity.

Background: The Cancer Health Awareness through screeNinG and Education (CHANGE) initiative delivers cancer awareness education with an emphasis on modifiable risk factors and navigation to screening for prostate, breast, and colorectal cancers to residents of public housing communities who experience significant negative social determinants of health.

Functional Outcomes and Satisfaction Rates in Patients Aged 80 Years or Older are Not Clinically Different From Their Younger (65 to 75 Years) Counterparts Following Total Hip Arthroplasty.

Background: As the population ages, the proportion of elderly patients requiring total hip arthroplasty (THA) increases, but it is not clear whether older age independently influences outcome. The aim was to assess function, quality of life, and satisfaction after THA in patients ≥ 80 years compared with those aged between 65 and 75 years when adjusting for confounding factors.

Methods: A single-center retrospective cohort study was performed between 2010 and 2019.

AAV9:PKP2 improves heart function and survival in a Pkp2-deficient mouse model of arrhythmogenic right ventricular cardiomyopathy.

Background: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a familial cardiac disease associated with ventricular arrhythmias and an increased risk of sudden cardiac death. Currently, there are no approved treatments that address the underlying genetic cause of this disease, representing a significant unmet need. Mutations in Plakophilin-2 (PKP2), encoding a desmosomal protein, account for approximately 40% of ARVC cases and result in reduced gene expression.

Complement dysregulation is a prevalent and therapeutically amenable feature of long COVID.

Background: Long COVID encompasses a heterogeneous set of ongoing symptoms that affect many individuals after recovery from infection with SARS-CoV-2. The underlying biological mechanisms nonetheless remain obscure, precluding accurate diagnosis and effective intervention. Complement dysregulation is a hallmark of acute COVID-19 but has not been investigated as a potential determinant of long COVID.

Investigating the association between educational attainment and allostatic load with risk of cancer mortality among African American women.

Background: African American (AA) women navigate the world with multiple intersecting marginalized identities. Accordingly, AA women have higher cumulative stress burden or allostatic load (AL) compared to other women. Studies suggest that AA women with a college degree or higher have lower AL than AA women with less than a high school diploma.

Improved Cardiac Function in Postischemic Rats Using an Optimized Cardiac Reprogramming Cocktail Delivered in a Single Novel Adeno-Associated Virus.

Background: Cardiac reprogramming is a technique to directly convert nonmyocytes into myocardial cells using genes or small molecules. This intervention provides functional benefit to the rodent heart when delivered at the time of myocardial infarction or activated transgenically up to 4 weeks after myocardial infarction. Yet, several hurdles have prevented the advancement of cardiac reprogramming for clinical use.

Gene and pathway based burden analyses in familial lymphoid cancer cases: Rare variants in immune pathway genes.

Genome-wide association studies have revealed common genetic variants with small effect sizes associated with diverse lymphoid cancers. Family studies have uncovered rare variants with high effect sizes. However, these variants explain only a portion of the heritability of these cancers.

Multiscale deep learning framework captures systemic immune features in lymph nodes predictive of triple negative breast cancer outcome in large-scale studies.

The suggestion that the systemic immune response in lymph nodes (LNs) conveys prognostic value for triple-negative breast cancer (TNBC) patients has not previously been investigated in large cohorts. We used a deep learning (DL) framework to quantify morphological features in haematoxylin and eosin-stained LNs on digitised whole slide images. From 345 breast cancer patients, 5,228 axillary LNs, cancer-free and involved, were assessed.

Association of Food Deserts and Food Swamps With Obesity-Related Cancer Mortality in the US.

Importance: Obesity-related cancers account for 40% of all cancers in the US. Healthy food consumption is a modifiable factor shown to reduce obesity-related cancer mortality, but residing in areas with less access to grocery stores (food deserts) or higher access to fast food (food swamps) reduces healthy food access and has been understudied.

Objective: To analyze the association of food deserts and food swamps with obesity-related cancer mortality in the US.

How Attributes of Place Threaten Community Trust in the American South: Opportunities for Improving Pandemic-Related Communication.

Dynamic Biobanking for Advancing Breast Cancer Research.

Longitudinal patient biospecimens and data advance breast cancer research through enabling precision medicine approaches for identifying risk, early diagnosis, improved disease management and targeted therapy. Cancer biobanks must evolve to provide not only access to high-quality annotated biospecimens and rich associated data, but also the tools required to harness these data. We present the Breast Cancer Now Tissue Bank centre at the Barts Cancer Institute as an exemplar of a dynamic biobanking ecosystem that hosts and links longitudinal biospecimens and multimodal data including electronic health records, genomic and imaging data, offered alongside integrated data sharing and analytics tools.

Skills and abilities to thrive in remote work: What have we learned.

The COVID-19 pandemic led to a rapid acceleration in the number of individuals engaging in remote work. This presented an opportunity to study individuals that were not voluntarily working remotely pre-pandemic and examine how they adapted and learned to achieve success in a remote work environment, at an organization that did not have substantial prior experience managing remote work. We used a semi-structured interview process to interview participants ( = 59) who occupied both Individual Contributor and Leadership levels at an organization and broadly representative across several important demographic characteristics.

CT coronary angiography first prior to rapid access chest pain clinic review: a retrospective feasibility study.

Objectives: Since rapid access chest pain clinics (RACPC) were established to streamline stable chest pain assessment, CT coronary angiography (CTCA) has become the recommended investigation for patients without known coronary artery disease (CAD), with well-defined indications. This single-centre retrospective study assessed the feasibility of General Practice (GP)-led CTCA prior to RACPC.

Methods: RACPC pathway patients without pre-existing CAD electronic records were reviewed (September-October 2019).

Intracerebroventricular dosing of N-sulfoglucosamine sulfohydrolase in mucopolysaccharidosis IIIA mice reduces markers of brain lysosomal dysfunction.

Mucopolysaccharidosis type IIIA (MPS IIIA) is a lysosomal storage disorder caused by N-sulfoglucosamine sulfohydrolase (SGSH) deficiency. SGSH removes the sulfate from N-sulfoglucosamine residues on the nonreducing end of heparan sulfate (HS-NRE) within lysosomes. Enzyme deficiency results in accumulation of partially degraded HS within lysosomes throughout the body, leading to a progressive severe neurological disease.

Perceived discrimination and Latina college students' depressive symptoms: The roles of dyadic coping with sisters and familism values.

Latinx young adults' experiences of discrimination are associated with high levels of depressive symptoms and examining protective factors that buffer the negative consequences of discrimination is important. In a sample of 195 Latina college students, predominately of Mexican origin, we examined associations between perceived discrimination and depressive symptoms, and how sisters' dyadic coping behaviors and familism values moderated this association. We conducted hierarchical regression analyses to test our study hypotheses.
