Multiplication rate variation of malaria parasites from hospital cases and community infections.

The significance of multiplication rate variation in malaria parasites needs to be determined, particularly for Plasmodium falciparum, the species that causes most virulent infections. To investigate this, parasites from cases presenting to hospital in The Gambia and from local community infections were culture-established and then tested under exponential growth conditions in a standardised six-day multiplication rate assay. The multiplication rate distribution was lower than seen previously in clinical isolates from another area in West Africa where infection is more highly endemic.

Who are the Parents? Risk and Resiliency Among Parents of Youth Receiving Intensive Home-Based Psychiatric Treatment.

Despite their explicit focus on family functioning and mounting evidence of the intergenerational mechanisms of childhood experiences (Zhang et al., 2022), very little is known about the parents of the high-risk youth receiving Intensive Home-Based Treatment (IHBT). Knowledge about parents' childhood experiences of risk and resilience, which are known to impact parenting behaviors, may provide insight into the complex clinical presentations frequently seen in this population and help guide the implementation of maximally effective interventions.

Body mass index trends over four years in persons with multiple sclerosis.

Background: The role of obesity in persons with multiple sclerosis (PwMS) is incompletely understood. Obesity predisposes individuals to a pro-inflammatory state and cardiovascular comorbidities, both of which can negatively impact MS disease course. A better understanding of weight trends in PwMS will inform optimal management of those who are overweight or obese.

Safety and immunogenicity of the ChAdOx1-MVA-vectored conserved mosaic HIVconsvX candidate T-cell vaccines in HIV-CORE 005.2, an open-label, dose-escalation, first-in-human, phase 1 trial in adults living without HIV-1 in the UK.

Background: An HIV-1 vaccine is long overdue. Although vaccine research focuses on the induction of broadly neutralising antibodies, challenging infections such as HIV-1 could require parallel induction of protective T cells. It is important to recognise that not all T cells contribute to protection equally.

Multi-ethnic heterozygote frequencies of cancer susceptibility genes to inform counseling of reproductive risk.

Purpose: Pathogenic germline variants (PGVs) in a subset of cancer predisposition genes (CPGs) are associated with adult-onset autosomal dominant (AD) cancer susceptibility and life-limiting autosomal recessive (AR) disease. Counseling in adult cancer genetics clinics regarding reproductive risk for PGV heterozygotes is limited.

Methods: Estimated heterozygote frequencies across ancestries were calculated for AD CPGs with AR risk (ATM, BRCA1, BRCA2, BRIP1, FH, NBN, MLH1, MSH2, MSH6, PMS2, RAD51C, SDHA, SDHB, and SDHD) from gnomADv.

Accuracy of Screening Tests for the Diagnosis of Urinary Tract Infections in Young Children.

Background: The objective of this study was to compare the accuracy of available tests for pyuria, including newer automated tests, and to examine the implications of requiring them for the diagnosis of urinary tract infections (UTIs).

Methods: We included children between 1 and 36 months of age undergoing bladder catheterization for suspected UTIs who presented to 1 of 3 pediatric centers. Using a positive urine culture result as the reference standard, we compared the sensitivity of 5 modalities for assessing pyuria at the cutoffs most often used clinically for detecting children with a positive culture result: leukocyte esterase on a dipstick, white blood cell (WBC) count on manual microscopy with and without using a hemocytometer, automated WBC enumeration using flow cytometry, and automated WBC enumeration using digital imaging with particle recognition.

Social media in pathology and laboratory medicine: A systematic review.

The use of social media platforms in pathology and medical laboratory science has increased in recent years, revolutionizing the way professionals in these fields interact, disseminate information, and collaborate. To gain an understanding of the current landscape regarding social media use in pathology and medical laboratory science, a novel systematic review was conducted. A search of PubMed, Medline, Embase, and Scopus was performed to identify articles evaluating social media use within pathology and medical laboratory science.

The underlying causes of differential migration: assumptions, hypotheses, and predictions.

Mechanisms governing the migratory decisions of birds have long fascinated ecologists and sparked considerable debate. Identifying factors responsible for variation in migration distance, also known as differential migration, has been a popular approach to understanding the mechanisms underlying migratory behaviour more generally. However, research progress has been slowed by the continued testing of overlapping, non-mechanistic, and circular predictions among a small set of historically entrenched hypotheses.

Exploring Caregiver Learning and Experiences Caring for a Child With Heart Failure: A Qualitative Study.

Background: Paediatric heart failure poses life-long, burdensome symptoms for the health care system and families. Diagnosis and discharge are stressful and anxiety-provoking for caregivers. They face uncertainty about their child's health and become responsible for administering complex care in the home.

Evaluation of the Interdisciplinary Care Home-bAsed Reablement Program (I-CHARP) for People Living With Cognitive Impairment and Dementia in Care Homes.

Background: Major knowledge and practice gaps exist in aged care home services to support independence of older people with dementia. This research evaluates an adaptation of a community-based rehabilitation model for care homes, namely Interdisciplinary Care Home-bAsed Reablement Program (I-CHARP), by examining whether (and, if so, how) I-CHARP produces its intended effects and how this programme can be practicably implemented, sustained and scaled up across care homes in Australia.

Methods: I-CHARP is a 4-month bio-behavioural-environmental rehabilitation model of care, integrated in care home services, supported through the deployment of an implementation strategy, the Research Enabled Aged Care Homes (REACH) network.

Community Pop-Up Clinic: Cascade of Care and HCV Treatment of Vancouver's Inner-City PWID Populations.

Elimination of HCV infection as a public health concern by the end of this decade will require a concerted effort in all target populations, including drug-users in the inner-city. Several strategies have been proposed to identify, engage and provide HCV-infected residents with antiviral therapy and maximise treatment and cure achievement. This study aims to assess the effectiveness of a multidisciplinary approach in delivering HCV treatment to people who inject drugs (PWID) within Vancouver's inner city.

ACTION-ARC Pediatric and Adult Congenital Heart Disease Ventricular Assist Device Adverse Event Definitions-2023.

Adverse events (AEs) experienced by children and adults with congenital heart disease (CHD) on ventricular assist devices (VADs) are sometimes unique to these populations. The Advanced Cardiac Therapies Improving Outcomes Network (ACTION) and the Academic Research Consortium (ARC) aimed to harmonize definitions of pediatric and CHD AEs for use in clinical trials, registries, and regulatory evaluation. Data from the ACTION registry and adjudication committee were used to adapt general mechanical circulatory support ARC definitions.

Host Jump of an Exotic Fish Rhabdovirus into a New Class of Animals Poses a Disease Threat to Amphibians.

Spring viremia of carp virus (SVCV) is a rhabdovirus that primarily infects cyprinid finfishes and causes a disease notifiable to the World Organization for Animal Health. Amphibians, which are sympatric with cyprinids in freshwater ecosystems, are considered non-permissive hosts of rhabdoviruses. The potential host range expansion of SVCV in an atypical host species was evaluated by testing the susceptibility of amphibians native to the Pacific Northwest.

User guide for Social Determinants of Health Survey data in the All of Us Research Program.

Objectives: Integration of social determinants of health into health outcomes research will allow researchers to study health inequities. The All of Us Research Program has the potential to be a rich source of social determinants of health data. However, user-friendly recommendations for scoring and interpreting the All of Us Social Determinants of Health Survey are needed to return value to communities through advancing researcher competencies in use of the All of Us Research Hub Researcher Workbench.

Controlling a new plasma regime.

Success of the UK's Spherical Tokamak for Energy Production (STEP) programme requires a robust plasma control system. This system has to guide the plasma from initiation to the burning phase, maintain it there, produce the desired fusion power for the desired duration and then terminate the plasma safely. This has to be done in a challenging environment with limited sensors and without overloading plasma-facing components.

Transoesophageal echocardiography in cardiac arrest: From the emergency department to the intensive care unit.

Cardiac arrest is a hyper-acute condition with a high mortality that requires rapid diagnostics and treatment. As such, point-of-care ultrasound (POCUS) has become a valuable tool in the assessment of these patients. While transthoracic echocardiography (TTE) is the more conventional modality used to find reversible causes of cardiac arrest, transoesophageal echocardiography (TOE) has been increasingly utilised due to its superior image quality, continuous imaging, and ability to be operated away from the patient's chest.

The impact of the introduction of tobacco product plain packaging on consumer responses in Ireland: a real-world policy evaluation stratified by socioeconomic groups.

Smoking prevalence remains high in Europe and widening socioeconomic group differences are driving health inequalities. While plain packaging policies disrupt tobacco industry tactics that sustain smoking, evidence of their equity impact is sparse. This study evaluated the implementation of plain packaging in Ireland in 2018 on consumer responses, overall and by the socioeconomic group.

Dental caries cause pain, infection and negatively impact quality of life. As part of population oral health improvement efforts in Saudi Arabia, this project aims to evaluate the effectiveness of a supervised toothbrushing programme in kindergartens.

Multidisciplinary lifestyle interventions for neurological disorders during the Silent phase (MINDS) study: a multi-omics randomized controlled trial protocol.

Introduction: Given the prevalence and staggering cost of neurological disorders, there is dire need for effective early detection and intervention tools. Emerging evidence suggests that multidisciplinary lifestyle interventions (MLI) may mitigate the risk and progression of neurological disorders. The objectives of this protocol are (1) to test the impact of MLI on the progression of neurological disorders and (2) to identify multi-omic biomarkers for early stages of neurological disease and the impact of MLIs on these biomarkers.

Neurodivergent patient experience in a tertiary children's hospital-a qualitative analysis.

Introduction: Sensory processing challenges are commonly encountered in pediatric patients, particularly in those who are neurodivergent. We previously developed a novel clinical pathway (named "Sensory Pathway") which aimed at improving patient care for those with sensory barriers via staff training, provision of sensory toolkits and early integration of families throughout the hospital stay. We hypothesized that utilization of this pathway will result in improved patient experience and provide valuable feedback to improve care.

Here, we examine one large cohort of GCs' evolving contributions to the literature, with the goal of facilitating worldwide professional development for GCs through scholarly activities.

Methods: Publications were cataloged by members of the Section of Genetic Counseling (Section), established at the Children's Hospital of Philadelphia and the University of Pennsylvania in 2014, including publication year, journal, impact factor, and author position.

Template-independent enzymatic synthesis of RNA oligonucleotides.

RNA oligonucleotides have emerged as a powerful therapeutic modality to treat disease, yet current manufacturing methods may not be able to deliver on anticipated future demand. Here, we report the development and optimization of an aqueous-based, template-independent enzymatic RNA oligonucleotide synthesis platform as an alternative to traditional chemical methods. The enzymatic synthesis of RNA oligonucleotides is made possible by controlled incorporation of reversible terminator nucleotides with a common 3'-O-allyl ether blocking group using new CID1 poly(U) polymerase mutant variants.
