Mapping the microRNA landscape in the older adult brain and its genetic contribution to neuropsychiatric conditions.

MicroRNAs (miRNAs) play a crucial role in regulating gene expression and influence many biological processes. Despite their importance, understanding of how genetic variation affects miRNA expression in the brain and how this relates to brain disorders remains limited. Here we investigated these questions by identifying microRNA expression quantitative trait loci (miR-QTLs), or genetic variants associated with brain miRNA levels, using genome-wide small RNA sequencing profiles from dorsolateral prefrontal cortex samples of 604 older adult donors of European ancestry.

Compassionate access to virus-specific T cells for adoptive immunotherapy over 15 years.

Adoptive T-cell immunotherapy holds great promise for the treatment of viral complications in immunocompromised patients resistant to standard anti-viral strategies. We present a retrospective analysis of 78 patients from 19 hospitals across Australia and New Zealand, treated over the last 15 years with "off-the-shelf" allogeneic T cells directed to a combination of Epstein-Barr virus (EBV), cytomegalovirus (CMV), BK polyomavirus (BKV), John Cunningham virus (JCV) and/or adenovirus (AdV) under the Australian Therapeutic Goods Administration's Special Access Scheme. Most patients had severe post-transplant viral complications, including drug-resistant end-organ CMV disease, BKV-associated haemorrhagic cystitis and EBV-driven post-transplant lymphoproliferative disorder.

Effects of brain microRNAs in cognitive trajectory and Alzheimer's disease.

microRNAs (miRNAs) have a broad influence on gene expression; however, we have limited insights into their contribution to rate of cognitive decline over time or Alzheimer's disease (AD). Given this, we tested associations of 528 miRNAs with cognitive trajectory, AD hallmark pathologies, and AD clinical diagnosis using small RNA sequencing from the dorsolateral prefrontal cortex of 641 community-based donors. We found 311 miRNAs differentially expressed in AD or its endophenotypes after adjusting for technical and sociodemographic variables.

Genetic regulation of microRNAs in the older adult brain and their contribution to neuropsychiatric conditions.

MicroRNAs are essential post-transcriptional regulators of gene expression and involved in many biological processes; however, our understanding of their genetic regulation and role in brain illnesses is limited. Here, we mapped brain microRNA expression quantitative trait loci (miR-QTLs) using genome-wide small RNA sequencing profiles from dorsolateral prefrontal cortex (dlPFC) samples of 604 older adult donors of European ancestry. miR-QTLs were identified for 224 miRNAs (48% of 470 tested miRNAs) at false discovery rate < 1%.

Correlates of lifestyle patterns among children in Singapore aged 10 years: the growing up in Singapore towards healthy outcomes (GUSTO) study.

Objective: To characterise lifestyle patterns (comprising dietary and movement behaviour aspects) of children in Singapore and examine the correlates of these patterns.

Design: An observational study approach was used. Children recorded their diet and activities over two weekdays and two weekend days on a validated web-based assessment, My E-Diary for Activities and Lifestyle (MEDAL).

Assessing the Utility, Impact, and Adoption Challenges of an Artificial Intelligence-Enabled Prescription Advisory Tool for Type 2 Diabetes Management: Qualitative Study.

Background: The clinical management of type 2 diabetes mellitus (T2DM) presents a significant challenge due to the constantly evolving clinical practice guidelines and growing array of drug classes available. Evidence suggests that artificial intelligence (AI)-enabled clinical decision support systems (CDSSs) have proven to be effective in assisting clinicians with informed decision-making. Despite the merits of AI-driven CDSSs, a significant research gap exists concerning the early-stage implementation and adoption of AI-enabled CDSSs in T2DM management.

Fulminant type 1 diabetes, an underrecognized and unique subtype of type 1 diabetes: A case series from Singapore.

Fulminant type 1 diabetes (FT1D) is a unique subtype of type 1 diabetes, characterized by acute absolute insulin deficiency, severe ketosis, and increased risk of hypoglycemia, glycemic variability and microvascular complications. Seven people with FT1D were identified from two tertiary centers in Singapore. Six were Chinese, the mean age was 35 years and all were lean (mean body mass index 20.

The cross-sectional and prospective associations of parental practices and environmental factors with 24-hour movement behaviours among school-aged Asian children.

Background: Parental practices and neighbourhood environmental factors may influence children's movement behaviours. We aimed to investigate the cross-sectional and prospective associations of parental practices and neighbourhood environmental factors with accelerometer-measured 24-hour movement behaviours (24 h-MBs) among school-aged children in Singapore.

Methods: The Growing Up in Singapore Towards healthy Outcomes (GUSTO) study collected information on dimensions of parental practices and neighbourhood environment at age 5.

Risk factors for therapy failure after incision and drainage alone for perianal abscesses in children.

Background: It is well known that recurrent perianal abscesses (PAs) and fistula-in-ano (FIA) are the main causes of therapy failure following incision and drainage (I&D) for PAs. But few studies have focused on the risk factors for therapy failure after I&D for PAs in children. In this study, we retrospectively examine the risk factors for therapy failure after I&D for PAs in children in a pediatric tertiary care institution.

Screening for obstructive sleep apnea (OSA) in children and adolescents with obesity: A scoping review of national and international pediatric obesity and pediatric OSA management guidelines.

Obstructive sleep apnea (OSA) is a prevalent complication that affects up to 60% of children and adolescents with obesity. It is associated with poorer cardiometabolic outcomes and neurocognitive deficits. Appropriate screening and intervention for OSA are crucial in the management of children with obesity.

Spotlighting 'Medical Collegiality'.

'Collegiality' comes from the Latin term 'Collegium', which essentially refers to a community of individuals bounded by their collective pursuit of a common goal. The concept has historical roots in both organised religion and academia, with its use subsequently extended to various industrial and corporate settings including healthcare. Nowadays, 'collegiality' has become a common buzzword adopted by the medical fraternity - often deemed as having a polite and respectful demeanour, maintaining cordial work relationships and being a team player who demonstrates willingness to help others and avoid speaking ill of fellow colleagues.

Cross-sectional and prospective associations between children's 24-h time use and their health-related quality of life: a compositional isotemporal substitution approach.

Background: Promoting active, balanced lifestyles among children may be an important approach to optimising their health-related quality of life (HRQoL). However, the relationships between children's movement behaviours and HRQoL remain unclear.

Methods: We examined the associations between movement behaviours (sleep, inactivity, light and moderate-to-vigorous intensity physical activity) assessed using accelerometers at ages 8 and 10 years and self-reported HRQoL scores (overall, and physical and emotional well-being, self-esteem, relationship with family and friends, and school functioning domains) at age 10 years among 370 children in a local birth cohort using compositional isotemporal substitution techniques.

Capsular warning syndrome-a case of atrial fibrillation and corona radiata infarct.

Background: Capsular warning syndrome (CWS) is a rare clinical syndrome characterised by recurrent and transient episodes of focal neurological deficits with high risk of infarction. The exact physiological mechanism of CWS remains unclear but is most commonly believed to be a result of haemodynamic insufficiency in diseased, small penetrating vessels. There are no defined treatment guidelines or established effective therapy.

Ischemic and hemorrhagic strokes in young adults: Comparison of functional outcomes and return to work after stroke.

Background: Functional recovery and return to work (RTW) after stroke are important rehabilitation goals that have significant impact on quality of life. Comparisons of functional outcomes and RTW between ischemic stroke (IS) and hemorrhagic stroke (HS), especially among young adults with stroke, have either been limited or yielded inconsistent results. We aimed to assess functional outcomes and ability to RTW in young adults with IS and HS, specifically primary spontaneous intracranial hemorrhage (SICH).

Cost-Effectiveness of Pharmacotherapy for the Treatment of Obesity in Adolescents.

Importance: Antiobesity pharmacotherapy is recommended for adolescents ages 12 years and older with obesity. Several medications have been approved by the US Food and Drug Administration for adolescent use, but the most cost-effective medication remains unclear.

Objective: To estimate the cost-effectiveness of lifestyle counseling alone and as adjunct to liraglutide, mid-dose phentermine and topiramate (7.

Anaphylatoxin Complement 5a in Pfizer BNT162b2-Induced Immediate-Type Vaccine Hypersensitivity Reactions.

The underlying immunological mechanisms of immediate-type hypersensitivity reactions (HSR) to COVID-19 vaccines are poorly understood. We investigate the mechanisms of immediate-type hypersensitivity reactions to the Pfizer BNT162b2 vaccine and the response of antibodies to the polyethylene glycol (PEG)ylated lipid nanoparticle after two doses of vaccination. Sixty-seven participants, median age 35 and 77.

Cost-effectiveness of adjuvant chemotherapy for high-risk stage II and stage III colon cancer in South Africa.

Background: Colon cancer incidence is rising in low- and middle-income countries (LMICs), where resource limitations and cost often dictate treatment decisions. In this study, we evaluate the cost-effectiveness of adjuvant chemotherapy for high-risk stage II and stage III colon cancer treatment in South Africa (ZA) and illustrate how such analyses can inform cancer treatment recommendations in a LMIC.

Methods: We created a decision-analytic Markov model to compare lifetime costs and outcomes for patients with high-risk stage II and stage III colon cancer treated with three adjuvant chemotherapy regimens in a public hospital in ZA: capecitabine and oxaliplatin (CAPOX) for 3 and 6 months, and capecitabine for 6 months, compared to no adjuvant treatment.

Etiologies, mechanisms, and risk factors of ischemic stroke in a young Asian adult cohort.

Objectives: Risk factors and causes of acute ischemic stroke (AIS) are more diverse in young adults, and traditional stroke classifications may be inadequate. Precise characterisation of AIS is important for guiding management and prognostication. We describe stroke subtypes, risk factors and etiologies for AIS in a young Asian adult population.
