TEARS: a longitudinal investigation of the prevalence, psychological associations and trajectory of poststroke emotionalism.

Objective: There are few longitudinal studies of poststroke emotionalism (PSE) and our understanding of the psychological associations of PSE is limited, constraining assessment of existing interventions and the development of new therapies. This study aimed to assess the prevalence and course of PSE over the first year poststroke, and its psychological associations.

Methods: Consenting stroke survivors who were physically and cognitively able to participate were assessed within 2 weeks, 6 and 12 months of stroke to determine PSE point prevalence using a diagnostic, semistructured PSE interview (Testing Emotionalism After Recent Stroke-Diagnostic Interview).

Epigenetic Modifications and Their Potential Contribution to Traumatic Brain Injury Pathobiology and Outcome.

Epigenetic information is not permanently encoded in the DNA sequence, but rather consists of reversible, heritable modifications that regulate the gene expression profile of a cell. Epigenetic modifications can result in cellular changes that can be long lasting and include DNA methylation, histone methylation, histone acetylation, and RNA methylation. As epigenetic modifications are reversible, the enzymes that add (epigenetic writers), the proteins that decode (epigenetic readers), and the enzymes that remove (epigenetic erasers) these modifications can be targeted to alter cellular function and disease biology.

Sperm selection with hyaluronic acid improved live birth outcomes among older couples and was connected to sperm DNA quality, potentially affecting all treatment outcomes.

Study Question: What effects did treatment using hyaluronic acid (HA) binding/selection prior to ICSI have on clinical outcomes in the Hyaluronic Acid Binding sperm Selection (HABSelect) clinical trial?

Summary Answer: Older women randomized to the trial's experimental arm (selection of sperm bound to immobilized (solid-state) HA) had the same live birth rates as younger women, most likely a result of better avoidance of sperm with damaged DNA.

What Is Known Already: Recent randomized controlled trials (RCTs) investigating the efficacy of HA-based sperm selection prior to ICSI, including HABSelect, have consistently reported reductions in the numbers of miscarriages among couples randomized to the intervention, suggesting a pathological sperm-mediated factor mitigated by prior HA-binding/selection. The mechanism of that protection is unknown.

Brief Strategy Training in Aging: Near Transfer Effects and Mediation of Gains by Improved Self-Regulation.

A common approach to cognitive intervention for adults is memory strategy training, but limited work of this type has examined intervention effects in relation to self-regulation (e.g., strategy usage, memory beliefs) and few have established near transfer (training-related performance gain on untrained tasks related to the target task).

Providers' definitions of quality and barriers to providing quality care: a qualitative study in rural Mpumalanga Province, South Africa.

Background: South Africa requires high-quality primary health care (PHC) to retain patients and optimize outcomes. While prior research has identified implementation challenges within the PHC system, there is less understanding of how providers define quality, their perceptions of barriers to providing quality care, and how they overcome these barriers. This study assesses provider views on quality at primary care clinics in a rural sub-district of Mpumalanga Province.

Mesenchymal tumor cells drive adaptive resistance of Trp53 breast tumor cells to inactivated mutant Kras.

As precision medicine increases the response rate of treatment, tumors frequently bypass inhibition, and reoccur. In order for treatment to be effective long term, the mechanisms enabling treatment adaptation need to be understood. Here, we report a mouse model that, in the absence of p53 and the presence of oncogenic Kras , develops breast tumors.

The microdissected gene expression landscape of nasopharyngeal cancer reveals vulnerabilities in FGF and noncanonical NF-κB signaling.

Nasopharyngeal cancer (NPC) is an Epstein-Barr virus (EBV)-positive epithelial malignancy with an extensive inflammatory infiltrate. Traditional RNA-sequencing techniques uncovered only microenvironment signatures, while the gene expression of the tumor epithelial compartment has remained a mystery. Here, we use Smart-3SEQ to prepare transcriptome-wide gene expression profiles from microdissected NPC tumors, dysplasia, and normal controls.

Safeguarding adolescent mental health in India (SAMA): study protocol for codesign and feasibility study of a school systems intervention targeting adolescent anxiety and depression in India.

Introduction: Symptoms of anxiety and depression in Indian adolescents are common. Schools can be opportune sites for delivery of mental health interventions. India, however, is without a evidence-based and integrated whole-school mental health approach.

Demographic, clinical and neuroimaging markers of post-stroke emotionalism: A preliminary investigation.

Introduction: Post stroke emotionalism (PSE) is a common but poorly understood condition. The value of altered brain structure as a putative risk factor for PSE alongside routinely available demographic and clinical variables has yet to be elucidated.

Methods: 85 patients were recruited from acute inpatient settings within 2 weeks of stroke.

Maternal physiology and blastocyst morphology are correlated with an inherent difference in peri-implantation human embryo development.

Objective: To determine what patient and embryo characteristics are correlated with the developmental potential of the peri-implantation embryo.

Design: Retrospective study.

Setting: Research laboratory.

HABIT (Health visitors delivering Advice in Britain on Infant Toothbrushing): a qualitative exploration of the acceptability of a complex oral health intervention.

Background: To explore the acceptability of the oral health intervention, HABIT (Health visitors delivering Advice in Britain on Infant Toothbrushing) to parents with young children aged 9-12 months and health visitors.

Methods: Following the delivery of the universal oral health intervention called HABIT, qualitative semi-structured interviews with parents and focus groups with health visitors were undertaken. Interviews were audio-recorded and transcribed.

Facilitators and barriers of preconception care in women with inflammatory bowel disease and rheumatic diseases: an explorative survey study in a secondary and tertiary hospital.

Background: Preconception care (PCC) is care prior to conception to optimize parental health, and health of the future child, through biomedical and behavioral changes. Providing PCC to all women with a wish to conceive will improve perinatal health. PCC is especially important for women with a chronic disease, such as inflammatory bowel disease (IBD) and rheumatic diseases (RD).

Outcome Prediction from Behaviour Change Intervention Evaluations using a Combination of Node and Word Embedding.

Findings from randomized controlled trials (RCTs) of behaviour change interventions encode much of our knowledge on intervention efficacy under defined conditions. Predicting outcomes of novel interventions in novel conditions can be challenging, as can predicting differences in outcomes between different interventions or different conditions. To predict outcomes from RCTs, we propose a generic framework of combining the information from two sources - i) the instances (comprised of surrounding text and their numeric values) of relevant attributes, namely the intervention, setting and population characteristics of a study, and ii) abstract representation of the categories of these attributes themselves.

Burden of allergic disease among ethnic minority groups in high-income countries.

The COVID-19 pandemic raised acute awareness regarding inequities and inequalities and poor clinical outcomes amongst ethnic minority groups. Studies carried out in North America, the UK and Australia have shown a relatively high burden of asthma and allergies amongst ethnic minority groups. The precise reasons underpinning the high disease burden are not well understood, but it is likely that this involves complex gene-environment interaction, behavioural and cultural elements.

Lower Risk of Recurrence with a Higher Induction Dose of Mesalazine and Longer Duration of Treatment in Ulcerative Colitis: Results from the Dutch, Non-Interventional, IMPACT Study.

Background And Aims: The dose and duration of mesalazine treatment for ulcerative colitis (UC) is a potentially important determinant of effectiveness, with evidence suggesting that continuing the induction dose for 6-12 months may improve outcomes; however, real-world data are lacking. We assessed mesalazine use in Dutch clinical practice, including how differences in dose and duration affected UC outcomes.

Methods: Adults with mild-to-moderate UC who received oral prolonged-release mesalazine de novo or had a dose escalation for an active episode were followed for 12 months in this non-interventional study (ClinicalTrials.

Enhancing autophagy in Alzheimer's disease through drug repositioning.

Alzheimer's disease (AD) is one of the biggest human health threats due to increases in aging of the global population. Unfortunately, drugs for treating AD have been largely ineffective. Interestingly, downregulation of macroautophagy (autophagy) plays an essential role in AD pathogenesis.

Complications and mortality associated with olecranon fractures in the elderly: a retrospective cohort comparison from a large level one trauma centre.

Background: Olecranon fractures in the elderly have an increasing incidence. This retrospective study aims to identify the complications and survivorship of these patients.

Methods: All patients >70 years old treated for an olecranon fracture at our institution were identified between 2007 and 2019.

Erythroid differentiation in mouse erythroleukemia cells depends on Tmod3-mediated regulation of actin filament assembly into the erythroblast membrane skeleton.

Erythroid differentiation (ED) is a complex cellular process entailing morphologically distinct maturation stages of erythroblasts during terminal differentiation. Studies of actin filament (F-actin) assembly and organization during terminal ED have revealed essential roles for the F-actin pointed-end capping proteins, tropomodulins (Tmod1 and Tmod3). Tmods bind tropomyosins (Tpms), which enhance Tmod capping and F-actin stabilization.

Patients' and Providers' Views on Optimal Evidence-Based and Scalable Interventions for Individuals at High Risk of HIV Treatment Failure: Sequential Explorations Among Key Stakeholders in Cape Town, South Africa.

To support translation of evidence-based interventions into practice for HIV patients at high risk of treatment failure, we conducted qualitative research in Cape Town, South Africa. After local health officials vetted interventions as potentially scalable, we held 41 in-depth interviews with patients with elevated viral load or a 3-month treatment gap at community clinics, followed by focus group discussions (FGDs) with 20 providers (physicians/nurses, counselors, and community health care workers). Interviews queried treatment barriers, solutions, and specific intervention options, including motivational text messages, data-informed counseling, individual counseling, peer support groups, check-in texts, and treatment buddies.

Comparison between dexmedetomidine and propofol on outcomes after coronary artery bypass graft surgery: a retrospective study.

Background: Dexmedetomidine (DEX) has a pharmacological profile that should allow rapid recovery and prevent undesirable outcomes such as pulmonary complications.

Methods: This large retrospective study compared the beneficial effects of perioperative infusion of DEX with propofol on the postoperative outcome after coronary artery bypass graft surgery. We reviewed patients' medical notes at Luoyang Central Hospital from 1st January 2012 to 31st December 2019.

The tocopherol transfer protein mediates vitamin E trafficking between cerebellar astrocytes and neurons.

Alpha-tocopherol (vitamin E) is an essential nutrient that functions as a major lipid-soluble antioxidant in humans. The alpha-tocopherol transfer protein (TTP) binds α-tocopherol with high affinity and selectivity and regulates whole-body distribution of the vitamin. Heritable mutations in the TTPA gene result in familial vitamin E deficiency, elevated indices of oxidative stress, and progressive neurodegeneration that manifest primarily in spinocerebellar ataxia.

Open science communication: The first year of the UK's Independent Scientific Advisory Group for Emergencies.

The COVID-19 pandemic has shone a light on the complex relationship between science and policy. Policymakers have had to make decisions at speed in conditions of uncertainty, implementing policies that have had profound consequences for people's lives. Yet this process has sometimes been characterised by fragmentation, opacity and a disconnect between evidence and policy.
