Animal life in the shallow subseafloor crust at deep-sea hydrothermal vents.

It was once believed that only microbes and viruses inhabited the subseafloor crust beneath hydrothermal vents. Yet, on the seafloor, animals like the giant tubeworm Riftia pachyptila thrive. Their larvae are thought to disperse in the water column, despite never being observed there.

Impact of obesity on the perinatal vaginal environment and bacterial microbiome: effects on birth outcomes.

species predominate the human vagina and are associated with positive vaginal health, including an acidic pH (<4.5). The prevalence of vaginal increases with increased oestrogen due to increased glycogen production within the vagina.

Metagenomic assessment of the bacterial breastfeeding microbiome in mature milk across lactation.

Introduction: Research has illustrated the presence of a diverse range of microbiota in human milk. The composition of the milk microbiome varies across different stages of lactation, emphasizing the need to consider the lactation stage when studying its composition. Additionally, the transfer of both milk and skin microbiota during breastfeeding is crucial for understanding their collective impact on infant health and development.

Comprehensive geriatric assessment for people with both COPD and frailty starting pulmonary rehabilitation: a mixed-methods feasibility trial.

Introduction: Many people with COPD experience frailty. Frailty increases risk of poor health outcomes, including non-completion of pulmonary rehabilitation. Integrated approaches to support people with COPD and frailty throughout and following rehabilitation are indicated.

Empowering Diabetics: Advancements in Smartphone-Based Food Classification, Volume Measurement, and Nutritional Estimation.

Diabetes has emerged as a worldwide health crisis, affecting approximately 537 million adults. Maintaining blood glucose requires careful observation of diet, physical activity, and adherence to medications if necessary. Diet monitoring historically involves keeping food diaries; however, this process can be labor-intensive, and recollection of food items may introduce errors.

Sex-Based Differences in Patients With Left Ventricular-Assisted Devices and Strokes.

Background: Sex-based differences in clinical outcomes among patients with stroke related to left ventricular assist devices (LVADs) are not well described.

Objectives: In this study, the authors examined differences in clinical characteristics and outcomes in men and women who had a stroke during LVAD hospitalization.

Methods: The National Inpatient Sample from 2010 and 2019 was used to identify patients with stroke during LVAD hospitalization.

Motivations for completing pulmonary rehabilitation - A qualitative analysis.

Previous studies have focused on demographic factors that might predict non-completion of pulmonary rehabilitation (PR). We aimed to identify key modifiable factors that promote completion of PR. A mixed methods survey was offered to participants completing a discharge assessment following PR.

Sex-specific associations between circadian-related genes and depression in UK Biobank participants highlight links to glucose metabolism, inflammation and neuroplasticity pathways.

Depressive disorders have increased in global prevalence, making improved management of these disorders a public health priority. Prior research has linked circadian clock genes to depression, either through direct interactions with mood-related pathways in the brain or by modulating the phase of circadian rhythms. Using machine learning and statistical techniques, we explored associations between 157,347 SNP variants from 51 circadian-related genes and depression scores from the patient health questionnaire 9 (PHQ-9) in 99,939 UK Biobank participants.

Interviews with policymakers in Australian health policy: Understanding the process of policy development.

Objective: To determine the barriers and enablers oral health and chronic disease policymakers identify during policy development.

Methods: Semi-structured interview questions were developed utilizing an interview guide and applying a knowledge mobilization framework. Reflective thematic analysis of the data was completed based on the research of Braun and Clarke encompassing a critical realist approach.

Remote pulmonary rehabilitation for interstitial lung disease: developing the model using experience-based codesign.

Background: Remote delivery may improve access to pulmonary rehabilitation (PR). Existing studies are largely limited to individuals with COPD, and the interventions have lacked codesign elements to reflect the needs and experiences of people with chronic respiratory disease, their carers/families and healthcare professionals. The aim of this study was, using experience-based codesign (EBCD), to collaborate with people with interstitial lung disease (ILD), their carers/families and healthcare professionals, to codesign a remote PR programme ready for testing in a future study.

Risk for Seasonal Affective Disorder (SAD) Linked to Circadian Clock Gene Variants.

Molecular pathways affecting mood are associated with circadian clock gene variants and are influenced, in part, by the circadian clock, but the molecular mechanisms underlying this link are poorly understood. We use machine learning and statistical analyses to determine the circadian gene variants and clinical features most highly associated with symptoms of seasonality and seasonal affective disorder (SAD) in a deeply phenotyped population sample. We report sex-specific clock gene effects on seasonality and SAD symptoms; genotypic combinations of CLOCK3111/ZBTB20 and PER2/PER3B were significant genetic risk factors for males, and CRY2/PER3C and CRY2/PER3-VNTR were significant risk factors for females.

Machine learning analyses reveal circadian clock features predictive of anxiety among UK biobank participants.

Mood disorders, including depression and anxiety, affect almost one-fifth of the world's adult population and are becoming increasingly prevalent. Mutations in circadian clock genes have previously been associated with mood disorders both directly and indirectly through alterations in circadian phase, suggesting that the circadian clock influences multiple molecular pathways involved in mood. By targeting previously identified single nucleotide polymorphisms (SNPs) that have been implicated in anxiety and depressive disorders, we use a combination of statistical and machine learning techniques to investigate associations with the generalized anxiety disorder assessment (GAD-7) scores in a UK Biobank sample of 90,882 individuals.

Findings from three methods to identify falls in hospitals: Results from the Ambient Intelligent Geriatric Management system fall prevention trial.

Objective: To (a) compare characteristics of patients who fall with those of patients who did not fall; and (b) characterise falls (time, injury severity and location) through three fall reporting methods (incident system reports, medical notes and clinician reports).

Methods: A substudy design within a stepped-wedge clinical trial was used: 3239 trial participants were recruited from two inpatient Geriatric Evaluation and Management Units and one general medicine ward in two Australian states. To compare the characteristics of patients who had fallen with those who had not, descriptive tests were used.

Evaluation of the Empower model of care for partial denture clients in a public oral health care setting.

Objective: To evaluate the effectiveness of the Empower model of care (EMC) on reducing the addition of teeth to removable partial dentures (RPD).

Methods: Data reports were generated through the Titanium electronic database to retrieve all clients at Monash Dental Services (MHDS) who participated in the EMC or received an RPD prior to the implementation of EMC was assessed over a two-year period to determine if they had additional teeth added to their partial dentures (PD). A logistic regression was performed testing whether a combination of socio-demographic and clinical variables, provided a multivariate explanation of the EMC outcome.

Effectiveness of E-learning on clinical application of dental injection anatomy via simulation manikins.

Purpose: E-learning is frequently integrated into dental education, yet little is known on the effectiveness of e-learning in both instilling foundational knowledge and facilitating translation of newly acquired knowledge and skill into clinical application. The objective of this study was to investigate the impact of learning modality on acquisition of knowledge and translation to clinical skill using objective feedback from oral anesthesia manikins and subjects' self-reported confidence scores.

Methods: This mixed-method study involved first year dental students (n = 52) who volunteered to participate in a learning intervention, simulation exercise, and survey in 2022.

The role of innovative modeling and imaging techniques in improving outcomes in patients with LVAD.

Heart failure remains a significant cause of mortality in the United States and around the world. While organ transplantation is acknowledged as the gold standard treatment for end stage heart failure, supply is limited, and many patients are treated with left ventricular assist devices (LVADs). LVADs extend and improve patients' lives, but they are not without their own complications, particularly the hemocompatibility related adverse events (HRAE) including stroke, bleeding and pump thrombosis.

Development and implementation of the lung volume reduction pulmonary rehabilitation tool to identify eligibility for lung volume reduction in people with chronic obstructive pulmonary disease during pulmonary rehabilitation.

Background: Completion of pulmonary rehabilitation is recognised in chronic obstructive pulmonary disease (COPD) guidelines as a key opportunity to consider systematically whether a respiratory review to assess potential suitability for a lung volume reduction (LVR) procedure might be appropriate. We describe the development of a simple decision-support tool (the LVR-PR tool) to aid clinicians working in pulmonary rehabilitation, to operationalise this process.

Methods: We took an iterative mixed methods approach, which was partnership-based and involved an initial consensus survey, focus groups and an observational study cohort at multiple pulmonary rehabilitation centres.

Hepatic Phospholipid Remodeling Modulates Insulin Sensitivity and Systemic Metabolism.

The liver plays a central role in regulating glucose and lipid metabolism. Aberrant insulin action in the liver is a major driver of selective insulin resistance, in which insulin fails to suppress glucose production but continues to activate lipogenesis in the liver, resulting in hyperglycemia and hypertriglyceridemia. The underlying mechanisms of selective insulin resistance are not fully understood.

Proxies of Emotion Dysregulation and Teen Dating Violence Perpetration: A Latent Profile Analysis.

Purpose: Teen dating violence (TDV) must be addressed as a public health issue due to its prevalence and association with negative health outcomes among victims. To prevent TDV, it is essential to examine the risk factors of dating violence perpetration's applicability to younger samples. Using a population health approach, this study explored the associations among variables that affect emotion regulation and TDV perpetration of multiple types among a diverse sample of high school students.

A Preliminary Experimental Study of Self-Objectification and Risky Sex Behavior Among a University Sample of Cisgender Women in the U.S.

Self-objectification is associated with a number of negative mental and behavioral outcomes. Though previous research has established associations between self-objectification and risky sex, no study to date has examined whether self-objectification affects propensity to engage in risky sex. The current research employed an experimental design to examine the effect of heightened self-objectification on a laboratory analog of risky sex (n = 181).
