Introduction: Compartment model analysis of diffusion MRI data provides unique information on the microstructural properties of white matter. However, studies relating compartment model microstructural measures to longitudinal cardiometabolic health data are rare.

Methods: 130 cognitively healthy participants in the Bogalusa Heart Study completed diffusion MRI scans.

Philadelphia chromosome-like B-cell acute lymphoblastic leukemia (Ph-like ALL) is driven by genetic alterations that induce constitutive kinase signaling and is associated with chemoresistance and high relapse risk in children and adults. Preclinical studies in the most common CRLF2-rearranged/JAK pathway-activated Ph-like ALL subtype have shown variable responses to JAK inhibitor-based therapies, suggesting incomplete oncogene addiction and highlighting a need to elucidate alternative biologic dependencies and therapeutic vulnerabilities, while the ABL-class Ph-like ALL subtype appears preferentially sensitive to SRC/ABL- or PDGFRB-targeting inhibitors. Which patients may be responsive versus resistant to tyrosine kinase inhibitor (TKI)-based precision medicine approaches remains a critical knowledge gap.

Background: Symptomatic rotator cuff tears often undergo surgical repair, which may be paired with various augmentation strategies to enhance structural healing rates. While many randomized controlled trials (RCTs) evaluate augmentation techniques, the statistical robustness of many findings in these studies is unknown. This systematic review aims to evaluate the continuous fragility index (CFI) of RCTs on augmentation techniques for rotator cuff repairs.

One often-overlooked consequence of stroke is a deficit in emotion regulation. Acting with awareness in everyday life has been found to support emotion regulation but it is an open question whether such associations generalize to stroke populations. Factors associated with emotion regulation in stroke survivors are key to inform rehabilitation efforts.

Background: Newborn screening (NBS) for cystic fibrosis (CF) was universally implemented in the United States in 2010 to improve disease outcomes. Despite universal screening, disparities in outcomes currently exist between people with CF (PwCF) with Black/African, Asian, Indigenous, and Latino/Hispanic ancestry in comparison to PwCF of European ancestry. This is in part because CFTR panels used for newborn screening are often based on variants common in European ancestries leading to higher rates of false negatives for PwCF from minoritized racial and ethnic groups.

The COVID-19 pandemic challenged older adults' health behaviours, making it even more difficult to engage in healthy diets and physical activity than it had been prepandemic. A resource to promote these could be social support. This study uses data from 136 older adults ( = 71.

Gait parameters and sarcopenia both predict falls risk among older adults. Our objective was to evaluate whether fast, easy-to-obtain measures of anterior thigh muscle by point of care ultrasound (POCUS) are significantly associated with standard gait measures. All subjects were referred from ambulatory geriatric medicine clinics at an academic center.

Objectives: Cognitive frailty is characterized by concurrent physical frailty and mild cognitive impairment and is associated with increased risk of falls. Exercise is an evidence-based strategy to prevent falls, but whether exercise reduces falls in people with cognitive frailty is unknown. We examined the effects of home-based exercise on subsequent falls among community-dwelling older adults with cognitive frailty who have previously fallen.

Introduction: One-third of adults aged 65+ fall annually. Injuries from falls can be devastating for individuals and account for 1.5% of annual healthcare spending.

Article Synopsis
  • Prolonged bed rest negatively impacts health, particularly cognitive performance in middle-aged and older adults, making it essential to explore exercise as a remedy.
  • A study involved 23 healthy adults aged 55-65, comparing 14 days of bed rest with and without daily exercise, assessing cognitive function using standardized tests.
  • Results indicated that those who exercised during bed rest had significantly better cognitive performance (lower variability) than those who did not, with a notable difference based on sex in the effects of exercise.

Article Synopsis
  • Military service is largely male-dominated, leading to research predominantly focusing on male soldiers, but findings suggest that female military members experience similar or higher rates of mental health issues like PTSD.
  • A longitudinal study of nearly 8,500 Australian Defence Force members tracked changes in mental health symptoms over five years, measuring factors like trauma exposure, resilience, and relationship satisfaction.
  • The study found that while lifetime trauma exposure was a key predictor of mental health disorders for both sexes, self-reported resilience served as a significant protective factor for females, whereas being in a significant relationship helped protect males from subthreshold mental disorders.

Article Synopsis
  • More and more people around the world are getting older, but there aren’t enough doctors who know how to take care of them well.
  • It’s super important to teach health workers the right skills so they can help older folks live healthier lives.
  • Experts want to create a clear definition of what a geriatrician is, to better train them and make sure older people get the best care possible.

The relationship between frailty and glycemic control in older adults with diabetes remains uncertain, mainly due to the fact that previous studies have not accounted for measures of body composition. In older adults with diabetes, we examined the association between three types of frailty measures and glycemic control, while accounting for fat-free mass (FFM) and waist circumference (WC). Eighty older adults (age ≥65, 27 women and 53 men, mean age 80.

Background: Frailty is generally a marker of worse prognosis. The impact of frailty on both in-hospital and long-term outcomes in ST-segment-elevation myocardial infarction (STEMI) patients has not been well described. Given this context, we aimed to determine the prevalence and impact of frailty on in-hospital and 1-year outcomes in STEMI patients undergoing primary percutaneous coronary intervention (pPCI).

  • The study aimed to assess patient expectations and attitudes towards cannabis for managing pain in individuals who experienced musculoskeletal injuries.
  • It was conducted as a survey among adult patients at three orthopaedic clinics in Ontario, focusing on their perceptions of cannabis's effectiveness and their usage preferences.
  • Results showed that patients believed cannabis could significantly alleviate pain and replace traditional analgesics, with many expressing a positive view toward its use for pain management while citing various reasons for not discussing it with their healthcare providers.

The existing literature consistently finds that emotional experiences and cortisol secretion are linked at the within-person level. Further, relationship partners tend to covary in emotional experience, and in cortisol secretion. However, we are only beginning to understand whether and how an individuals' emotions are linked to their relationship partners' cortisol secretion.

Background: Emerging evidence suggests that repetitive transcranial magnetic stimulation (rTMS) enhances cognition in mild cognitive impairment (MCI). Accelerated intermittent theta burst stimulation (iTBS) rTMS protocols are promising as they substantially reduce burden by shortening the treatment course, but the safety, feasibility, and acceptability of iTBS have not been established in MCI.

Methods: 24 older adults with amnestic MCI (aMCI) due to possible Alzheimer's disease enrolled in a phase I trial of open-label accelerated iTBS to the left dorsolateral prefrontal cortex (8 stimulation sessions of 600 pulses of iTBS/day for 3 days).

Objective: The purpose of this study was to implement a 2-phase approach to rapidly increase the number of annual wellness visits (AWVs) and build a sustainable model at 3 study units (Mayo Clinic in Rochester, Minnesota, and clinics in 2 regions of Mayo Clinic Health System), which collectively serve approximately 80 000 patients who qualify for an AWV annually.

Methods: In the rapid improvement phase, beginning in July 2022, goals at the facilities were reoriented to prioritize AWVs, educate staff on existing AWV resources, and create low-effort workflows so that AWVs could be incorporated into existing patient appointments. Staff at all 3 study units worked independently and iterated quickly.
