In Alzheimer's disease (AD) research, the 5xFAD mouse model is commonly used as a heterozygote crossed with other genetic models to study AD pathology. We investigated whether the parental origin of the 5xFAD transgene affects plaque deposition. Using quantitative light-sheet microscopy, we found that paternal inheritance of the transgene led to a 2-fold higher plaque burden compared with maternal inheritance, a finding consistent across multiple 5xFAD colonies.

The World Health Organisation (WHO) has set goals to eliminate hepatitis C (HCV) as a global health threat by 2030. To meet this goal, Australia must increase testing and diagnosis, including expanding access to care through community pharmacists. This study aims to explore community pharmacists' preparedness to discuss and offer HCV testing and treatment.

T cells have been identified as correlates of protection in viral infections. However, the level of vaccine-induced T cells needed and the extent to which they alone can control acute viral infection in humans remain uncertain. Here we conducted a double-blind, randomized controlled trial involving vaccination and challenge in 33 adult human volunteers, using the live-attenuated yellow fever (YF17D) and chimeric Japanese encephalitis-YF17D (JE/YF17D) vaccines.

Nasopharyngeal carcinoma (NPC) presents a substantial clinical challenge due to the limited understanding of its genetic underpinnings. Here we conduct the largest scale whole-exome sequencing association study of NPC to date, encompassing 6,969 NPC cases and 7,100 controls. We unveil 3 germline genetic variants linked to NPC susceptibility: a common rs2276868 in RPL14, a rare rs5361 in SELE, and a common rs1050462 in HLA-B.

Article Synopsis
  • The study investigated the clinical and radiological factors affecting the outcomes of acute ischemic stroke patients with isolated posterior cerebral artery (PCA) occlusion treated only with medical management.
  • A total of 585 patients were analyzed, revealing that 56% experienced poor functional outcomes, which were linked to older age, higher NIHSS scores, larger infarct volumes, and not receiving intravenous thrombolysis (IVT).
  • The research highlighted that factors like age, NIHSS score, infarct volume, and IVT status significantly influenced outcomes, while finding that complete recanalization after 24 hours improved recovery chances.

  • Mentoring is essential for professional identity formation (PIF), as it fosters personalized relationships and integrates program values, though its mechanisms remain unclear.
  • A systematic scoping review examined existing literature on mentoring support from 2000 to mid-2023, using rigorous methodology to analyze themes and categories.
  • Key findings highlight four domains vital to effective mentoring support: definitions and roles, personalisation, shepherding, and PIF, showcasing the importance of adapting mentoring approaches to meet individual mentee needs.

Aptamers have emerged as prominent ligands in clinical diagnostics because they provide various advantages over antibodies, such as quicker generation time, reduced manufacturing costs, minimal batch-to-batch variability, greater modifiability, and improved thermal stability. In the present study, we isolated and characterized DNA aptamers that can specifically bind to the hemolysin E (HlyE) antigen of Salmonella Typhi for future development of typhoid diagnostic tests. The DNA aptamers against Salmonella Typhi HlyE were isolated using systematic evolution of ligands by exponential enrichment (SELEX), and their binding affinity and specificity were assessed utilizing enzyme-linked oligonucleotide assay (ELONA).

Article Synopsis
  • Medical education focuses on developing Professional Identity Formation (PIF) in students, emphasizing reflective practice amid challenges like resource constraints.
  • Group non-written reflections (GNWR) involve facilitator-led discussions to foster shared reflection, potentially improving PIF in medical training.
  • A systematic scoping review identified 98 relevant studies, highlighting four key areas: the value of GNWR, its structure, models of reflective practice, and elements of communities that aid socialization.

Article Synopsis
  • This study looks at how student pharmacists handle arguments at work using something called politeness theory.
  • Fifty-six students took part in pretend job situations where they had conflicts with coworkers, either those with less authority or those at the same level.
  • The results showed that most students would speak up in these conflicts, but different situations led them to use different communication styles, and they could benefit from practicing these skills in safe settings before starting real jobs.

Introduction: The last national emergency department (ED) inventory was performed in 2007, and major changes in population demographics, healthcare needs and infrastructure have since occurred. We sought to obtain an updated inventory of EDs in Singapore to identify and describe changes in their characteristics and capabilities across the years.

Methods: In 2021, the National Emergency Department Inventories (NEDI) instrument was administered to the leadership of Singapore EDs.

Introduction: Wheelchair training is pivotal for safety, independence, and occupational engagement in the community, yet adults coming into wheelchair use often receive insufficient or untailored training. This research aimed to understand the range and type of manual wheelchair training approaches that exist for adults commencing wheelchair use.

Method: A systematic scoping review involved searching eight electronic databases and grey literature up to September 2023.

Introduction: Having a lower extremity amputation is a life-changing decision for people living with a diabetes-related foot ulcer. Although previous research has described both positive and negative lifestyle and function outcomes of diabetes-related amputations, limited research has been conducted on the decision-making processes leading up to the amputation. This study aimed to explore the perspectives of persons, healthcare practitioners and experts (including academics and specialists) on decision-making for people with a diabetes-related foot ulcer who may require a non-emergency amputation.

Background: Mentoring can help shape how medical students think, feel, and act as physicians. Yet, the mechanism in which it influences this process of professional identity formation (PIF) remains poorly understood. Through the lens of the ecological systems theory, this study explores the interconnected and dynamic system of mentoring relationships and resources that support professional development and growth within the Palliative Medicine Initiative (PMI), a structured research peer mentoring program.

  • Over 20 million individuals in the U.S. identified as Asian American, Native Hawaiian, or Pacific Islander in 2022, with varying immigration histories and health needs, yet cervical cancer studies have often lumped this diverse group together.
  • This study aimed to investigate cervical cancer disparities specifically within disaggregated Asian American, Native Hawaiian, or Pacific Islander groups by analyzing data from 122,926 cervical cancer patients diagnosed between 2004 and 2020.
  • Results showed that Asian American, Native Hawaiian, or Pacific Islander patients were diagnosed at earlier stages of cervical cancer compared to non-Hispanic White patients, with the largest subgroups being Filipino, Chinese, Indian/Pakistani, Vietnamese, and Korean Americans

Unlabelled: Prostate cancer is frequently treated with radiotherapy. Unfortunately, aggressive radioresistant relapses can arise, and the molecular underpinnings of radioresistance are unknown. Modern clinical radiotherapy is evolving to deliver higher doses of radiation in fewer fractions (hypofractionation).

Amyloid-β (Aβ) is thought to be neuronally derived in Alzheimer's disease (AD). However, transcripts of amyloid precursor protein (APP) and amyloidogenic enzymes are equally abundant in oligodendrocytes (OLs). By cell-type-specific deletion of Bace1 in a humanized knock-in AD model, APP, we demonstrate that OLs and neurons contribute to Aβ plaque burden.
