Exploration of Alzheimer's disease-related gene expression following high-intensity and moderate-intensity exercise interventions.

Objectives: There are currently 29 genome regions that demonstrate associations with Alzheimer's disease (AD) risk. Regular physical exercise can promote systemic change in gene expression and may modify the risk of cognitive decline and AD. This study is a secondary analysis of a randomised controlled trial and examines the effect of a six-month exercise intervention versus control on AD-related gene expression.

T-cell immunosuppression in sepsis is augmented by sciatic denervation-induced skeletal muscle atrophy.

Skeletal muscle atrophy is a known risk factor for immunosuppressive conditions and for a poor prognosis in sepsis. However, its immunopathology has not been experimentally elucidated. This study investigated the effects of skeletal muscle atrophy on the immunopathology of sepsis.

A Qualitative Study of Aboriginal Peoples' Health Care Experiences With Chronic Obstructive Pulmonary Disease.

Aboriginal Australians experience a high prevalence of chronic obstructive pulmonary disease (COPD), with high rates of potentially preventable hospitalisations. However, little is known about Aboriginal peoples' experiences of living with COPD and how they navigate health care systems. This study used thematic analysis and Aboriginal methodology to explore Aboriginal peoples' lived experiences of COPD, their health care journey from receiving a diagnosis of COPD to the clinical management, and the impact of COPD on their daily lives.

Challenges and considerations for antifungal prophylaxis in children with acute myeloid leukemia.

Introduction: Children receiving treatment for acute myeloid leukemia (AML) are at high risk of invasive fungal disease (IFD). Evidence from pediatric studies support the efficacy of antifungal prophylaxis in reducing the burden of IFD in children receiving therapy for AML, yet existing antifungal agents have specific limitations and comparative data to inform the optimal prophylactic approach are lacking.

Areas Covered: This review summarizes the epidemiology of invasive fungal disease (IFD) and current antifungal prophylaxis recommendations for children with acute myeloid leukemia (AML).

Diagnostic Overshadowing of Chronic Hepatitis C in People With Mental Health Conditions Who Inject Drugs: A Scoping Review.

Diagnostic overshadowing refers to a phenomenon whereby people with mental health conditions encounter inadequate or delayed medical attention and misdiagnosis. This occurs when physical symptoms are mistakenly attributed to their mental health condition. This paper presents a scoping review focusing on direct causes and background factors of diagnostic overshadowing in the context of hepatitis C infection in people who inject drugs and have concurrent mental health conditions.

Evidence for Altered White Matter Organization After Mild Traumatic Brain Injury: A Scoping Review on the Use of Diffusion Magnetic Resonance Imaging and Blood-Based Biomarkers to Investigate Acute Pathology and Relationship to Persistent Post-Concussion Symptoms.

Mild traumatic brain injury (mTBI) is the most common form of traumatic brain injury. Post-concussive symptoms typically resolve after a few weeks although up to 20% of people experience these symptoms for >3 months, termed persistent post-concussive symptoms (PPCS). Subtle white matter (WM) microstructural damage is thought to underlie neurological and cognitive deficits experienced post-mTBI.

Mapping Emotion Regulation Patterns Within the Alternative Model of Personality Disorders Personality Traits.

Personality pathology is associated with emotional problems that are potentially attributable to problematic emotion regulation strategy patterns. We evaluated the emotion regulation strategies associated with the pathological personality traits in the Alternative Model of Personality Disorders (AMPD). A total of 504 participants completed measures of AMPD traits and strategy usage, which were analyzed using hierarchical regressions and latent profile analysis (LPA).

Incremental prognostic value of cardiovascular magnetic resonance imaging in patients with severe LV dysfunction undergoing coronary artery bypass grafting.

Background: Coronary artery disease (CAD) remains a significant global health issue, particularly when complicated by left ventricular ejection fraction (LVEF) < 35%. Although coronary artery bypass grafting (CABG) is recommended for such cases, the unclear prognosis necessitates further investigation.

Method: This retrospective study aimed to determine whether cardiovascular magnetic resonance (CMR) imaging provides additional prognostic value in guiding effective clinical management.

Myeloperoxidase Deficiency: A Rare Case.

Myeloperoxidase (MPO) is found in the lysosomes of monocytes and neutrophils, serving as a crucial component in the elimination of infections through the process of phagocytosis via neutrophils. Consequently, individuals with MPO deficiency exhibit a significantly heightened susceptibility to serious infections and chronic inflammatory diseases. In a clinical case, a 37-year-old Iranian woman presented with a chronic history of bacterial and fungal infections dating back to her childhood.

B cell epitope mapping: The journey to better vaccines and therapeutic antibodies.

B-cell epitope mapping is an approach that can identify and characterise specific antigen binding sites of B-cell receptors and secreted antibodies. The ability to determine the antigenic clusters of amino acids bound by B-cell clones provides unprecedented detail that will aid in developing novel and effective vaccine targets and therapeutic antibodies for various diseases. Here, we discuss conventional approaches and emerging techniques that are used to map B-cell epitopes.

Decrease in Haemoglobin in Association with Aneurysm Volume Loss after Endovascular Repair of Abdominal Aortic Aneurysm.

Background: Anaemia (low haemoglobin [Hb]) is well known to be associated with high mortality and adverse cardiac events following surgical treatment of abdominal aortic aneurysm (AAA). However, little is known about the relationship of AAA volume and Hb level alterations with endovascular repair of AAA. This study aimed to examine the changes in the Hb level and aneurysm volume before and after endovascular aneurysm repair (EVAR) for AAA and determine the relationship between the post-operative Hb level and the volume loss of AAA.

Timing and location dictate monocyte fate and their transition to tumor-associated macrophages.

Tumor-associated macrophages (TAMs) are a heterogeneous population of cells whose phenotypes and functions are shaped by factors that are incompletely understood. Herein, we asked when and where TAMs arise from blood monocytes and how they evolve during tumor development. We initiated pancreatic ductal adenocarcinoma (PDAC) in inducible monocyte fate-mapping mice and combined single-cell transcriptomics and high-dimensional flow cytometry to profile the monocyte-to-TAM transition.

Advances in Extraction, Structure, and Physiochemical Properties of Sorghum Kafirin for Biomaterial Applications: A Review.

Kafirin is an endosperm-specific hydrophobic protein found in sorghum grain and the waste by-product from sorghum biorefineries known as sorghum dried distillers' grain with solubles (DDGS). Because of kafirin's poor nutritional profile (negative nitrogen balance, slow digestibility, and lack of some essential amino acids), its direct human use as a food is restricted. Nevertheless, increased focus on biofuel production from sorghum grain has triggered a new wave of research to use sorghum DDGS kafirin as a food-grade protein for biomaterials with diverse applications.

Down syndrome-associated leukaemias: current evidence and challenges.

Children with Down syndrome (DS) are at increased risk of developing haematological malignancies, in particular acute megakaryoblastic leukaemia and acute lymphoblastic leukaemia. The microenvironment established by abnormal haematopoiesis driven by trisomy 21 is compounded by additional genetic and epigenetic changes that can drive leukaemogenesis in patients with DS. GATA-binding protein 1 () somatic mutations are implicated in the development of transient abnormal myelopoiesis and the progression to myeloid leukaemia of DS (ML-DS) and provide a model of the multi-step process of leukaemogenesis in DS.

Pain prevalence, intensity, and association with neuropsychiatric symptoms of dementia in immigrant and non-immigrant aged care residents in Australia.

Pain recognition for culturally diverse people is complex as pain experience is subjective and influenced by cultural background. We compared the prevalence, intensity, and association of pain with neuropsychiatric symptoms (NPS) between immigrants and non-immigrants living with dementia in residential aged care homes (RACHs) who were referred to two Dementia Support Australia programs. Immigrant status was defined by the documented country of birth.

Improving radiology information systems for inclusivity of transgender and gender-diverse patients: what are the problems and what are the solutions? A systematic review.

Introduction: In medical radiation science (MRS), radiology information systems (RISs) record patient information such as name, gender and birthdate. The purpose of RISs is to ensure the safety and well-being of patients by recording patient data accurately. However, not all RISs appropriately capture gender, sex or other related information of transgender and gender-diverse (TGD) patients, resulting in non-inclusive and discriminatory care.

Generation of two induced pluripotent stem cell lines from an Usher syndrome type 1B patient with the homozygous c.496del MYO7A variant.

Usher syndrome (USH) is the most common cause of inherited deaf-blindness. Here, we produced the LEIi020-A and LEIi020-B induced pluripotent stem cell (iPSC) lines from dermal fibroblasts derived from a patient with USH1B caused by inheritance of homozygous c.496del variants in MYO7A using episomal plasmids encoding OCT4, SOX2, KLF4, L-MYC, LIN28, mir302/367 microRNA and shRNA for TP53.

A Mixed-Methods Cohort Study Evaluating the Impact of a One-Day Well-Being Course for Anesthesia Providers Working in Low-Resource Settings.

Background: Burnout, depression, and anxiety are increasingly recognized as common among health care providers. Risks for these conditions are exacerbated in low-resource settings by excessive workload, high disease burden, resource shortage, and stigma against mental health issues. Based on discussions and requests to learn more about burnout during the Vital Anaesthesia Simulation Training (VAST), our team developed VAST Wellbeing, a 1-day course for health care providers in low-resource settings to recognize and mitigate burnout and to promote personal and professional well-being.

Insights into the Clinical, Biological and Therapeutic Impact of Copy Number Alteration in Cancer.

Copy number alterations (CNAs), resulting from the gain or loss of genetic material from as little as 50 base pairs or as big as entire chromosome(s), have been associated with many congenital diseases, de novo syndromes and cancer. It is established that CNAs disturb the dosage of genomic regions including enhancers/promoters, long non-coding RNA and gene(s) among others, ultimately leading to an altered balance of key cellular functions. In cancer, CNAs have been associated with almost all steps of the disease: predisposition, initiation, development, maintenance, response to treatment, resistance, and relapse.

Use of Smart Glasses (Assisted Reality) for Western Australian X-ray Operators' Continuing Professional Development: A Pilot Study.

Previous studies have explored use of smart glasses in telemedicine, but no study has investigated its use in teleradiography. The purpose of this study was to implement a six-month pilot program for Western Australian X-ray operators (XROs) to use smart glasses to obtain assisted reality support in their radiography practice from their supervising radiographers, and evaluate its effectiveness in terms of XROs' competence improvement and equipment usability. Pretest-posttest design with evaluation of the XROs' competence (including their X-ray image quality) and smart glasses usability by XROs in two remote centers and their supervising radiographers from two sites before and after the program using four questionnaire sets and X-ray image quality review was employed in this experimental study.
