Background: This study examined the experiences of Indigenous youth and young adults with pediatric onset chronic health conditions who had or were about to transition from pediatric to adult healthcare services. Transition is the process by which youth develop the knowledge and self-management skills needed to manage their health condition, ideally beginning around age 12-13 and continuing until the mid-20s. There is a growing body of literature on healthcare transition, but there is an absence of literature on Indigenous youth, who face additional barriers to accessing healthcare relative to non-Indigenous Canadians.

Indigenous Peoples face inequities in health and healthcare access due to colonial history and systems. To work towards the Truth and Reconciliation Commission of Canada's Calls to Action and the United Nations Declaration on the Rights of Indigenous Peoples, Alberta Health Services has collaborated with a Wisdom Council of engaged Elders and Indigenous community members to tailor programmes for Indigenous Peoples. The Indigenous Support Line (ISL) was created based on the Wisdom Council's advice to provide an Indigenous-specific concerns line, which later expanded into a telehealth line to address any health questions or access issues, including health system navigation and access to Western and Indigenous health and wellness supports.

Article Synopsis
  • There is a critical need for Indigenous health care data in Canada to better inform health services for Indigenous communities.
  • Implementing a voluntary self-reported Indigenous identifier in health records faces challenges and requires strong relationships and adequate training to ensure trust and proper usage.
  • Successful implementation depends on Indigenous-led data governance and considering the historical distrust of health systems among Indigenous peoples.

  • - An exploratory study in Alabama aimed to improve HIV testing rates among Black young men who have sex with men (BYMSM) by interviewing both BYMSM and outreach workers about their experiences and recommendations for better outreach efforts.
  • - Data from 56 BYMSM (average age 24) and 12 outreach workers (average age 39, mostly male and Black) revealed five key themes: promoting testing earlier, increasing visibility and outreach efforts, creating connections through shared experiences, using nonjudgmental communication, and enhancing HIV knowledge among BYMSM.
  • - The study concluded that building trust is crucial for effective HIV testing promotion among BYMSM, with recommendations to start prevention discussions at a younger age and train outreach workers in

Importance: Cancer survivors experience accelerated functional decline that threatens independence and quality of life. Previous studies have suggested that vegetable gardening may improve diet, physical activity, and physical function in this vulnerable population, which comprises more than 5% of the US population.

Objective: To assess whether diet, physical activity and functioning, and other outcomes improved in older cancer survivors assigned to a vegetable gardening intervention compared with a waitlist.

Background: The impact of midwifery, and especially Indigenous midwifery, care for Indigenous women and communities has not been comprehensively reviewed. To address this knowledge gap, we conducted a mixed-methods systematic review to understand Indigenous maternal and infant outcomes and women's' experiences with midwifery care.

Methods: We searched nine databases to identify primary studies reporting on midwifery and Indigenous maternal and infant birth outcomes and experiences, published in English since 2000.

Background: Children with mobility disabilities, including those with cerebral palsy, have limited options and limited time to exercise to manage their cardiometabolic health and cardiorespiratory fitness. Regular cardiovascular exercise during childhood is a critical health behavior for preventing health decline in adulthood. Thus, there is an urgent need for accessible, age-appropriate, convenient exercise modalities in this group.

Research articles in the clinical and translational science literature commonly use quantitative data to inform evaluation of interventions, learn about the etiology of disease, or develop methods for diagnostic testing or risk prediction of future events. The peer review process must evaluate the methodology used therein, including use of quantitative statistical methods. In this manuscript, we provide guidance for peer reviewers tasked with assessing quantitative methodology, intended to complement guidelines and recommendations that exist for manuscript authors.

Inflammation is thought to contribute to the etiology of interstitial cystitis/bladder pain syndrome (IC/BPS). It is well-known that disruption in metabolism in immune cells contributes to inflammation in several inflammatory diseases. The purpose of this study was to investigate whether cellular bioenergetics is altered in monocytes and lymphocytes from women with IC/BPS, and if these alterations correlate with systemic inflammatory markers.

Article Synopsis
  • Consensus guidelines suggest collecting two serum concentrations of vancomycin to estimate its effectiveness, but using Bayesian software allows for monitoring with just one concentration, although this method lacks extensive validation.
  • A retrospective study involving 300 adult patients with gram-positive infections found that those receiving AUC-guided therapy had better treatment outcomes, including higher success rates and lower instances of acute kidney injury (VA-AKI) compared to those on trough-guided therapy.
  • Results indicate that AUC-guided therapy not only improved patient safety by reducing VA-AKI but also allowed for more efficient and flexible monitoring, ultimately leading to better overall outcomes without loss of treatment efficacy.

  • A study was conducted to assess the clinical efficacy and safety of vancomycin loading doses in patients with MRSA infections, comparing outcomes before and after a change in dosing protocol at a hospital.
  • The new protocol reserved loading doses for hemodynamically unstable patients, while previously all patients received them based on weight.
  • Results showed no significant difference in inpatient mortality or other secondary outcomes between patients receiving loading doses and those who did not, indicating that routine loading doses may not improve outcomes in stable patients.

Despite well-documented global declines in physical activity (PA) during the COVID-19 pandemic, little is known regarding the specific impact among underserved, rural Alabama counties. This is concerning as this region was already disproportionately burdened by inactivity and related chronic diseases and was among the hardest hit by COVID-19. Thus, the current study examined the effect of COVID-19 on PA in four rural Alabama counties.

Background And Aims: Jejunostomy tube placements provides enteral access for feeding in eligible patients who cannot meet their nutritional needs by mouth. They can be surgically placed laparoscopically (lap-J) or with the use of a conventional open laparotomy approach (open-J). Recently, direct percutaneous endoscopic jejunostomy (DPEJ) has emerged as an alternative owing to its low cost and shorter recovery times.

  • The study evaluates the importance of team science skills among collaborative biostatisticians, highlighting a gap in graduate programs which often emphasize technical skills over collaborative and leadership abilities.
  • A survey of 343 biostatisticians across various career stages and sectors identified 16 essential skills, with significant differences in skill importance based on career stage and degree.
  • The findings suggest the need for improved training opportunities in graduate programs and on-the-job initiatives to develop the necessary team science skills for a skilled quantitative workforce.

  • Children with sickle cell disease (SCD) often experience abdominal pain, which may be linked to various gastrointestinal (GI) issues, but there's limited data on how frequently this occurs or how it’s evaluated.
  • A study analyzed 1279 encounters of children with abdominal pain, finding that 23% were associated with such pain, particularly in older children with sickle cell anemia (SCA) and those with specific blood count parameters.
  • Less than half of these patients received a GI-specific evaluation in the emergency department, suggesting that improving these evaluations could help diagnose or rule out GI problems and expand the understanding of abdominal pain in SCD patients.
