This paper examines the concept of centredness in health care, with a particular focus on person-centred care. While the principle of centring care is widely accepted, the concept of a 'centre' remains ambiguous, complicating its implementation. The paper defines centredness, questions the necessity of a central focus and explores alternative models.

Hepatocellular carcinoma (HCC) remains a leading cause of cancer-related deaths worldwide, and a large proportion is attributable to viral causes, including hepatitis B (HBV) and C viruses (HCV). The pathogenesis of viral-mediated HCC can differ between HBV and HCV, but it is unclear how much these differences influence the tumors' final molecular and immune profiles. Additionally, there are known sex differences in the molecular etiology of HCC, but sex differences have not been explored in the context of viral-mediated HCC.

Patients heterozygous for germline CBL loss-of-function (LOF) variants can develop myeloid malignancy, autoinflammation, or both, if some or all of their leukocytes become homozygous for these variants through somatic loss of heterozygosity (LOH) via uniparental isodisomy. We observed an upregulation of the inflammatory gene expression signature in whole blood from these patients, mimicking monogenic inborn errors underlying autoinflammation. Remarkably, these patients had constitutively activated monocytes that secreted 10 to 100 times more inflammatory cytokines than those of healthy individuals and CBL LOF heterozygotes without LOH.

Article Synopsis
  • Ubiquitination is the process of attaching ubiquitin to proteins, but recent studies show that certain E3 ligases, like DELTEX, can modify non-protein substrates, including ADP-ribose.* -
  • The DELTEX family member DTX3L specifically adds ubiquitin to single-stranded and double-stranded DNA/RNA, requiring its C-terminal RING and DTC domains for this catalytic activity.* -
  • This research highlights the novel role of DTX3L in ubiquitinating nucleic acids, paving the way for future exploration of the functional significance of this modification.*

Introduction Globally, yoga has gained popularity as a health-promoting and disease-prevention discipline. The common health conditions prompting yoga use include musculoskeletal disorders, mental health conditions, asthma, fibromyalgia, arthritis, diabetes, and cancers. Although the therapeutic benefits of using yoga are well documented, little is known about the characteristics of yoga instructors (YIs) and yoga users (YUs) in New Zealand (NZ).

Characterizing DNA methylation patterns is important for addressing key questions in evolutionary biology, geroscience, and medical genomics. While costs are decreasing, whole-genome DNA methylation profiling remains prohibitively expensive for most population-scale studies, creating a need for cost-effective, reduced representation approaches (i.e.

As genomics technologies advance, there is a growing demand for computational biologists trained for genomics analysis but instructors face significant hurdles in providing formal training in computer programming, statistics, and genomics to biology students. Fully online learners represent a significant and growing community that can contribute to meet this need, but they are frequently excluded from valuable research opportunities which mostly do not offer the flexibility they need. To address these opportunity gaps, we developed an asynchronous course-based undergraduate research experience (CURE) for computational genomics specifically for fully online biology students.

The toxicity of ATR-107, a human anti-interleukin-21 receptor (IL-21R) monoclonal antibody (mAb), was evaluated in CD-1 mice and cynomolgus monkeys after single-dose intravenous (IV) administration, and in Sprague-Dawley (SD) rats and cynomolgus monkeys after weekly IV and subcutaneous (SC) administration in 13-week toxicity studies that included recovery. Adverse liver necrosis, diffuse bridging fibrosis, and higher liver enzymes occurred in rats in the low-dose IV group (10 mg/kg), but not at 50 or 250 mg/kg IV, and not following SC administration despite overlapping systemic ATR-107 exposures. Similar findings were not seen in mice or cynomolgus monkeys.

Article Synopsis
  • Industrialized environments, while offering benefits such as better education and lower infection rates, may contribute to brain atrophy, prompting a comparison of brain volume changes in industrialized versus non-industrialized populations.* -
  • The Tsimane and Moseten are two indigenous Bolivian groups studied, with the Tsimane showing increased brain volume in certain areas with age, while the UK Biobank participants experience a significant decrease in brain volume over time, particularly in frontal and temporal regions.* -
  • The findings suggest that lifestyle factors, including physical activity levels, may influence brain volume changes, with Tsimane males exhibiting surprising increases in some brain areas, while Tsimane females show greater decreases compared to UK Biobank females.*

Challenges in identifying tumor-rejecting neoantigens limit the efficacy of neoantigen vaccines to treat cancers, including cutaneous squamous cell carcinoma (cSCC). A minority of human cSCC tumors shared neoantigens, supporting the need for personalized vaccines. Using a UV-induced mouse cSCC model which recapitulated the mutational signature and driver mutations found in human disease, we found that CD8 T cells constrain cSCC.

Electronic Health Record (EHR) systems are often configured to address challenges and improve patient safety for persons with Parkinson's disease (PWP). For example, EHR systems can help identify Parkinson's disease (PD) patients across the hospital by flagging a patient's diagnosis in their chart, preventing errors in medication and dosing through the use of clinical decision support, and supplementing staff education through care plans that provide step-by-step road maps for disease-based care of a specific patient population. However, most EHR-based solutions are locally developed and, thus, difficult to scale widely or apply uniformly across hospital systems.

Poor oral health is associated with cardiovascular disease and dementia. Potential pathways include sepsis from oral bacteria, systemic inflammation, and nutritional deficiencies. However, in post-industrialized populations, links between oral health and chronic disease may be confounded because the lower socioeconomic exposome (poor diet, pollution, and low physical activity) often entails insufficient dental care.

Background: In industrialized populations, low male testosterone is associated with higher rates of cardiovascular mortality. However, coronary risk factors like obesity impact both testosterone and cardiovascular outcomes. Here, we assess the role of endogenous testosterone on coronary artery calcium in an active subsistence population with relatively low testosterone levels, low cardiovascular risk and low coronary artery calcium scores.

Dysregulation of the PI3K/AKT pathway is a common occurrence in high-grade serous ovarian carcinoma (HGSOC), with the loss of the tumour suppressor PTEN in HGSOC being associated with poor prognosis. The cellular mechanisms of how PTEN loss contributes to HGSOC are largely unknown. We here utilise time-lapse imaging of HGSOC spheroids coupled to a machine learning approach to classify the phenotype of PTEN loss.

In many populations, the aε (ε) allele increases the risk for several chronic diseases of aging, including dementia and cardiovascular disease; despite these harmful effects at later ages, the ε allele remains prevalent. We assess the impact of ε on fertility and its proximate determinants (age at first reproduction, interbirth interval) among the Tsimane, a natural fertility population of forager-horticulturalists. Among 795 women aged 13 to 90 (20% ε carriers), those with at least one ε allele had 0.

Article Synopsis
  • Vesiculoviruses are promising candidates for cancer treatment due to their rapid replication and ability to target tumors effectively while avoiding immune system detection.
  • Researchers developed a synthetic chimeric virus called VMG, which combines elements from Morreton virus and vesicular stomatitis virus, and found it effectively induced cell death in various sarcoma types across different species.
  • Initial safety tests in healthy mice showed no toxicity, and while VMG didn't suppress tumors in one model, it successfully stimulated immune responses, showing potential as a new oncolytic virotherapy for sarcoma.

Article Synopsis
  • This study investigates brain aging and dementia in two indigenous South American populations, the Tsimane and Moseten, to understand brain volume (BV) changes in a nonindustrialized context.
  • It analyzes data from 1,165 individuals aged 40 to 94, revealing that BV declines with age but at a slower rate compared to industrialized populations.
  • The findings support the "embarrassment of riches" model, suggesting that a balanced energy intake during active lifestyles promotes better brain health, while excess body weight negatively impacts BV in modern societies.

A growing body of work has addressed human adaptations to diverse environments using genomic data, but few studies have connected putatively selected alleles to phenotypes, much less among underrepresented populations such as Amerindians. Studies of natural selection and genotype-phenotype relationships in underrepresented populations hold potential to uncover previously undescribed loci underlying evolutionarily and biomedically relevant traits. Here, we worked with the Tsimane and the Moseten, two Amerindian populations inhabiting the Bolivian lowlands.
