Molecular correlates for HPV-negative head and neck cancer engraftment prognosticate patient outcomes.

There is a pressing need to improve risk stratification and treatment selection for HPV-negative head and neck squamous cell carcinoma (HNSCC) due to the adverse side effects of treatment. One of the most important prognostic features is lymph nodes involvement. Previously, we demonstrated that tumor formation in patient-derived xenografts (i.

Loss of the mitochondrial protein mitoNEET in mice is associated with cognitive impairments and increased neuroinflammation.

Background: Mitochondrial dysfunction is implicated in several neurodegenerative diseases associated with memory and cognitive deficits, including Alzheimer's disease. Changes in bioenergetic function results in reactive oxygen species, oxidative damage and consequently neuroinflammation, which contributes to neuronal cell loss.

Objective: In this study, we evaluated the impact of the loss of the redox active [2Fe-2S] mitochondrial-associated protein mitoNEET (CISD1) on neuroinflammation and cognition using an age-appropriate preclinical model.

Signal-in-noise detection across the lifespan in a mouse model of presbycusis.

The auditory system is constantly tasked with detecting acoustic cues in complex auditory environments. Difficulty hearing speech in noise, largely a result of energetic masking, is a major communication complaint of the elderly, which impacts a third of the global population over 65. The neural mechanisms responsible for processing sound in background noise and subsequently achieving release from energetic masking remain obscure.

Skin health of urban-living Aboriginal children attending a primary care Aboriginal Community Controlled Health Organisation clinic.

Background And Objectives: Despite increasing urbanisation, little is known about skin health for urban-living Aboriginal children and young people (CYP, aged <18 years). This study aimed to investigate the primary care burden and clinical characteristics of skin conditions in this cohort.

Method: A one-year retrospective cohort study of urban-living Aboriginal CYP presenting for general practitioner (GP) consultation at an Aboriginal Community Controlled Health Organisation (ACCHO) was conducted.

Vacuum evaporation coupled with anaerobic digestion for process intensification and ammonia recovery: Model development, validation and scenario analysis.

A mathematical model for vacuum evaporation process was developed, which was experimentally validated at different initial pHs and temperatures for ammonia removal from anaerobically digested sludge. Six scenarios were evaluated by combining vacuum evaporation process with anaerobic digestion using anaerobic digestion model 1. These scenarios included a control, a pretreatment by vacuum evaporation, a post-treatment by vacuum evaporation at pH 9, a post-treatment by conventional evaporation (100 °C), an intensification with vacuum-concentrated recycled digestate back to the digester, and a second intensification at pH 9.

A review of general cognitive-behavioral programs in English and Welsh prisons and probation services: Three decades of quasi-experimental evaluations.

For over 30 years, general cognitive-behavioral programs have contributed to the rehabilitation services offered within His Majesty's Prison and Probation Service in England and Wales. There is an extensive body of international evidence that demonstrates the effectiveness of such interventions as a correctional strategy. However, there is widespread variability of program effects associated with the standards of implementation.

From Striving to Thriving: Mitigating Anti-Black Family Racism to Maximize Health Outcomes in Black Children.

Certain inequities and injustices represent long-standing, recurring challenges that disproportionately affect many Black communities in the United States. Despite decades of efforts to eliminate these problems and improve outcomes in health, housing, education, and employment, a significant number of Black families are still "surviving" and not "thriving." The effects of historical and ongoing discriminatory policies continue to increase risk for adverse outcomes among Black people and their families.

Exhaustive Search of Dietary Intake Biomarkers as Objective Tools for Personalized Nutrimetabolomics and Precision Nutrition Implementation.

Objective: To conduct an exhaustive scoping search of existing literature, incorporating diverse bibliographic sources to elucidate the relationships between metabolite biomarkers in human fluids and dietary intake.

Background: The search for biomarkers linked to specific dietary food intake holds immense significance for precision health and nutrition research. Using objective methods to track food consumption through metabolites offers a more accurate way to provide dietary advice and prescriptions on healthy dietary patterns by healthcare professionals.

The impact of item order on the factor structure of the PTSD Checklist for DSM-5.

The PTSD Checklist for DSM-5 (PCL-5) is the most widely used self-report measure of posttraumatic stress disorder (PTSD) and is frequently modeled as having four correlated factors consistent with the DSM-5 symptom structure. Some researchers have argued that item order may influence factor structure. Although two studies have examined this, they were both based on DSM-IV criteria, and neither utilized a randomized design.

PRMT1 inhibition perturbs RNA metabolism and induces DNA damage in clear cell renal cell carcinoma.

In addition to the ubiquitous loss of the VHL gene in clear cell renal cell carcinoma (ccRCC), co-deletions of chromatin-regulating genes are common drivers of tumorigenesis, suggesting potential vulnerability to epigenetic manipulation. A library of chemical probes targeting a spectrum of epigenetic regulators is screened using a panel of ccRCC models. MS023, a type I protein arginine methyltransferase (PRMT) inhibitor, is identified as an antitumorigenic agent.

Biofortification as a food-based strategy to improve nutrition in high-income countries: a scoping review.

Biofortification (increasing the micronutrient content of food before harvest) has been successfully used to nutritionally improve staple foods in low- and middle-income countries. This approach could also help address micronutrient shortfalls in at-risk populations in high-income countries (HICs), however, the potential of biofortification interventions in this context is not well understood. The aim of this scoping review is to assess the nature and extent of available research evidence on biofortified foods in relation to human consumption in HICs.

Skin health of Aboriginal children living in urban communities.

Background: Skin concerns are frequent among urban-living Aboriginal children, yet specialist dermatology consultations are limited with studies highlighting the need for improved cultural security. Through newly established paediatric dermatology clinics at two urban Aboriginal Community Controlled Health Organisations (ACCHOs), we aimed to describe clinic and patient data, including disease frequencies and associations, to inform dermatology service provision and advocacy.

Methods: A prospective cohort study of Aboriginal children and young people (CYP, 0-18 years) attending Aboriginal Health Practitioner (AHP) co-ordinated paediatric dermatology clinics at two urban ACCHOs.

PTEN Loss Shapes Macrophage Dynamics in High-Grade Serous Ovarian Carcinoma.

High-grade serous ovarian carcinoma (HGSC) remains a disease with poor prognosis that is unresponsive to current immune checkpoint inhibitors. Although PI3K pathway alterations, such as PTEN loss, are common in HGSC, attempts to target this pathway have been unsuccessful. We hypothesized that aberrant PI3K pathway activation may alter the HGSC immune microenvironment and present a targeting opportunity.

Viral infections in atopic dermatitis.

Individuals with atopic dermatitis are susceptible to frequent viral skin infections due to compromised epidermal barrier function and immune dysregulation. The diagnosis and management of viral infections in atopic dermatitis can be challenging due to various clinical phenotypes and overlapping clinical features. We reviewed the literature for the diagnosis, aetiology, management, differential diagnoses and complications of these viral infections to provide an up-to-date clinical overview for clinicians involved in caring for patients with atopic dermatitis, including features specific to patients with skin of colour.

Evaluation of an ambulatory care pathway for patients with nitrous oxide-induced myeloneuropathy.

Introduction: Cases of nitrous oxide (NO)-induced myeloneuropathy are increasing at UK hospitals. At our centre, a dedicated ambulatory care pathway, endorsed nationally, was established to treat and monitor patients with NO-myeloneuropathy in 2021 and refined through three audit cycles. We analysed the outcomes of patients on this pathway to better understand factors associated with non-engagement.

Caregiver-reported barriers to care for children and adults with Williams Syndrome.

Individuals with Williams syndrome (WS) may experience a variety of medical, behavioral, and educational concerns. The primary objective of this study was to assess barriers to health care for patients with WS, primarily using the Barriers to Care Questionnaire (BCQ), and to assess whether various demographic factors are correlated with these barriers. A REDCap survey was distributed using the Williams Syndrome Association Research Registry.

Recreational nitrous oxide and thrombotic events: a case series.

Background: The study aimed to elucidate the prevalence of nitrous oxide (N2O) usage in patients with unexplained venous thromboembolism (VTE), highlighting the potential association with hyperhomocysteinaemia (HHcy).

Methods: We conducted a retrospective study at the Royal London Hospital, examining cases of N2O-related VTE from March to August 2023. Among 50 patients identified, four (8%) had recent unprovoked VTE.

A food-exchange model for achieving the recommended dietary intakes for saturated fat in Irish children: analysis from the cross-sectional National Children's Food Survey II.

Objective: To identify the main foods determining SFA intakes and model the impact of food exchanges to improve compliance with dietary fat recommendations in Irish children.

Design: Estimated food and nutrient intakes were obtained from a cross-sectional study, the National Children's Food Survey II. Participants were categorised into low, medium and high SFA consumers, and the contribution of food categories to SFA intakes was compared.

L-Ergothioneine slows the progression of age-related hearing loss in CBA/CaJ mice.

The naturally occurring amino acid, l-ergothioneine (EGT), has immense potential as a therapeutic, having shown promise in the treatment of other disease models, including neurological disorders. EGT is naturally uptaken into cells via its specific receptor, OCTN1, to be utilized by cells as an antioxidant and anti-inflammatory. In our current study, EGT was administered over a period of 6 months to 25-26-month-old CBA/CaJ mice as a possible treatment for age-related hearing loss (ARHL), since presbycusis has been linked to higher levels of cochlear oxidative stress, apoptosis, and chronic inflammation.

Massed written exposure therapy delivered to veterans with posttraumatic stress symptoms on an acute inpatient mental health unit.

Written exposure therapy (WET) is a brief, manualized trauma-focused treatment typically delivered in five individual weekly sessions. Given the brevity and effectiveness of WET, researchers have begun to focus on its delivery in a massed format. However, only one case study examining massed delivery has been published to date.

Chronic phase advances reduces recognition memory and increases vascular cognitive dementia-like impairments in aged mice.

Disrupted or atypical light-dark cycles disrupts synchronization of endogenous circadian clocks to the external environment; extensive circadian rhythm desynchrony promotes adverse health outcomes. Previous studies suggest that disrupted circadian rhythms promote neuroinflammation and neuronal damage post-ischemia in otherwise healthy mice, however, few studies to date have evaluated these health risks with aging. Because most strokes occur in aged individuals, we sought to identify whether, in addition to being a risk factor for poor ischemic outcome, circadian rhythm disruption can increase risk for vascular cognitive impairment and dementia (VCID).

Where Are All the Specialists? Current Challenges of Integrating Specialty Care Into Population-Based Total Cost of Care Payment Models.

The Centers for Medicare & Medicaid Services Innovation Center (CMMI) has set the goal for 100% of traditional Medicare beneficiaries to be part of an accountable care relationship by 2030. Lack of meaningful financial incentives, intolerable or unpredictable risk, infrastructure costs, patient engagement, voluntary participation, and operational complexity have been noted by the provider and health care delivery community as barriers to participation or reasons for exiting programs. In addition, most piloted and implemented population-based total cost of care (PB-TCOC) payment models have focused on the role of the primary care physician being the accountability (that is, attributable) leader of a patient's multifaceted care team as well as acting as the mayor of the "medical neighborhood," leaving the role of specialty care physicians undefined.
