ABSTRACT

IMPORTANCE: Despite research supporting the benefits of early palliative care, timely initiation by gynecologic oncology patients is reportedly low, which may limit the effectiveness of palliative care.

OBJECTIVE: To investigate the association of the timing of palliative care initiation with the aggressiveness of end-of-life care using established quality indicators among patients with ovarian cancer.

DESIGN, SETTING, AND PARTICIPANTS: This population-based retrospective cohort study of ovarian cancer decedents used linked administrative health care data to identify palliative care provision across all health care sectors and health care professionals (specialist and nonspecialist) and end-of-life quality indicators in Ontario, Canada, from 2006 to 2018. Data analyses were performed July 12, 2024.

MAIN OUTCOMES AND MEASURES: The primary outcome was the associations between the timing of palliative care and end-of-life quality indicators, including emergency department use, hospital or intensive care unit admission in the last 30 days of life, chemotherapy in last 14 days of life, death in the hospital, and a composite measure of aggressive care. Late palliative care was defined as 3 months or less prior to death.

RESULTS: There were 8297 ovarian cancer decedents. Their mean (SD) age at death was 69.6 (13.1) years, and their mean (SD) oncologic survival was 2.8 (3.9) years. Among 3958 patients with known cancer stage, 3495 (88.3%) presented with stage III or IV disease. One-third of patients (2667 [32.1%]) received late palliative care in the final 3 months of life. Results of multivariable regression analysis indicated that any palliative care initiated earlier than 3 months before death was associated with lower rates of aggressive end-of-life care (odds ratio [OR], 0.47 [95% CI, 0.37-0.60]), death in hospital (OR, 0.54 [95% CI, 0.45-0.65]), and intensive care unit admission (OR, 0.46 [95% CI, 0.27-0.76]). Specialist palliative consultation from 3 months up to 6 monts before death was associated with decreased likelihood of late chemotherapy (OR, 0.46 [95% CI, 0.24-0.88]).

CONCLUSIONS: Findings from this cohort study suggested that early palliative care may be associated with less-aggressive end-of-life care than late palliative care. Implementation strategies for early palliative care initiation are needed to optimize care quality and health resource utilization at the end of life.

ABSTRACT

IMPORTANCE: Community Paramedicine at Clinic (CP@clinic) is a chronic disease prevention program that decreases 911 calls for emergency medical services, but its wider system effects are unknown.

OBJECTIVE: To evaluate the effects of CP@clinic vs usual care on individual-level health service utilization outcomes.

DESIGN, SETTING, AND PARTICIPANTS: This open-label, pragmatic cluster randomized clinical trial evaluated all residents 55 years or older in 30 social housing buildings in Ontario, Canada, that had (1) a unique postal code, (2) at least 50 apartments, (3) 60% or more residents 55 years or older, and (4) a similar building for pairing (15 intervention and 15 control buildings, pair-matched randomization). The 12-month intervention had a staggered start date from January 1, 2015, to December 1, 2015, and ended between December 31, 2015, and November 30, 2016. Administrative health data analysis was conducted in May 2022.

INTERVENTION: CP@clinic was a health promotion and disease prevention program led by specially trained community paramedics who held weekly drop-in sessions in social housing buildings. These paramedics conducted 1-on-1 risk assessments, provided health education and referrals to relevant community resources, and, with consent, sent assessments to family physicians. Control buildings received usual care (universal health care, including free primary and specialty medical care).

MAIN OUTCOME AND MEASURES: Individual-level health service utilization was measured from administrative health data, with ED visits via ambulance as the primary outcome; secondary outcomes included ED visits for any reason, primary care visits, hospitalizations, length of hospital stay, laboratory tests, receipt of home care, transfer to long-term care, and medication initiation. Generalized estimating equations were used to estimate intervention effects on individual-level health service utilization, accounting for trial design and individual-level baselines.

RESULTS: The 30 social housing buildings had 3695 residents (1846 control and 1849 intervention participants; mean [SD] age, 72.8 [9.1] years; 2400 [65.0%] female). Intention-to-treat analysis found no significant difference in ED visits by ambulance (445 of 1849 [24.1%] vs 463 of 1846 [25.1%]; adjusted odds ratio [AOR], 0.97; 95% CI, 0.89-1.05) but found higher antihypertensive medication initiation (74 of 500 [14.8%] vs 47 of 552 [8.5%]; AOR, 1.74; 95% CI, 1.19-2.53) and lower anticoagulant initiation (48 of 1481 [3.2%] vs 69 of 1442 [4.8%]; AOR, 0.68; 95% CI, 0.53-0.86) in the intervention arm vs the control arm. CP@clinic attendance was associated with higher incidence of primary care visits (adjusted incidence rate ratio, 1.10; 95% CI, 1.03-1.17), higher odds of receiving home care (AOR, 1.07; 95% CI, 1.01-1.13), and lower odds of long-term care transfers (AOR, 0.32; 95% CI, 0.13-0.81).

CONCLUSIONS AND RELEVANCE: In this cluster randomized clinical trial of CP@clinic, the intervention did not affect the rate of ED visits by ambulance; however, there were increased primary care visits and connections to home care services, which may have increased antihypertensive medication initiation and reduced long-term care transfers from social housing. Health policymakers should consider CP@clinic’s impact as an upstream approach to improve care for older adults with low income.

ABSTRACT

IMPORTANCE: The underrepresentation of Black men in the health care workforce, particularly among physician assistants and associates (PAs), represents a missed opportunity to alleviate shortages of health care professionals and enhance workforce diversity. Increasing the number of Black men in the training pipeline could significantly benefit education, patient care, and overall health outcomes.

OBJECTIVE: To analyze patterns from 2013 to 2021 among Black men applying to and matriculating into PA programs and compare these figures with the age-specific US population of Black men.

DESIGN, SETTING, AND PARTICIPANTS: This cohort study assessed deidentified application and matriculation data from the Central Application Service for Physician Assistants (CASPA) for PA training programs in the US, alongside US Census data. CASPA applicants reporting race and gender identities as Black male were included. Data were obtained March 10, 2023, from the 2012-2013 to the 2020-2021 application cycles; data were analyzed from June 2023 to May 2024.

EXPOSURES: Black male applicants and matriculation.

MAIN OUTCOMES AND MEASURES: Patterns and proportion of Black male applicants and matriculants to PA programs relative to total rates and expected numbers.

RESULTS: From 2013 to 2021, PA programs grew 64.3%, with an increase in applicants from 19 761 to 30 196 and matriculants from 6192 to 11 115. Despite this growth, the representation of Black men among applicants (from 435 to 732) and matriculants (from 73 to 156) remained stagnant, averaging 2.2% and 1.2%, respectively, significantly lower than their 8.7% (3 920 231 individuals aged 20-29 years) representation in the US Census. In 2021, the matriculation rate for Black men (156 of 732 [21.3%]) was notably lower than the matriculation rate for all applicants (11 115 of 30 196 [36.8%]). Based on the expected proportion of Black men in the PA applicant age range, there should have been 2641 applicants (actual: 732) and 972 matriculants (actual: 156) across 308 PA programs in 2021; these numbers indicate that, per program, approximately 9 applicants would have to have been evaluated and 3 matriculated to achieve parity, in contrast to the mean of 2 applicants and 1 matriculant per 2 programs.

CONCLUSIONS AND RELEVANCE: In this cohort study of PA applicants and matriculants, Black men remained substantially underrepresented despite overall growth of PA training programs. The low representation among matriculants was due in part to the low numbers of applicants but also to substantially lower matriculation success. This persistent underrepresentation highlights systemic barriers and underscores the need for targeted interventions to achieve a more representative health care workforce. To achieve equitable admissions, each PA program should aim to evaluate 9 Black male applicants and matriculate 3 Black men annually.

ABSTRACT

IMPORTANCE: Obesity is associated with increased severity of COVID-19. Whether obesity is associated with an increased risk of post-acute sequelae of SARS-CoV-2 infection (PASC) among pediatric populations, independent of its association with acute infection severity, is unclear.

OBJECTIVE: To quantify the association of body mass index (BMI) status before SARS-CoV-2 infection with pediatric PASC risk, controlling for acute infection severity.

DESIGN, SETTING, AND PARTICIPANTS: This retrospective cohort study occurred at 26 US children’s hospitals from March 2020 to May 2023 with a minimum follow-up of 179 days. Eligible participants included children and young adults aged 5 to 20 years with SARS-CoV-2 infection. Data analysis was conducted from October 2023 to January 2024.

EXPOSURES: BMI status assessed within 18 months before infection; the measure closest to the index date was selected. The BMI categories included healthy weight (≥5th to <85th percentile for those aged 5-19 years or ≥18.5 to <25 for those aged >19 years), overweight (≥85th to <95th percentile for those aged 5-19 years or ≥25 to <30 for for those aged >19 years), obesity (≥95th percentile to <120% of the 95th percentile for for those aged 5-19 years or ≥30 to <40 for those aged >19 years), and severe obesity (≥120% of the 95th percentile for those aged 5-19 years or ≥40 for those aged >19 years).

MAIN OUTCOMES AND MEASURES: To identify PASC, a diagnostic code specific for post-COVID-19 conditions was used and a second approach used clusters of symptoms and conditions that constitute the PASC phenotype. Relative risk (RR) for the association of BMI with PASC was quantified by Poisson regression models, adjusting for sociodemographic, acute COVID severity, and other clinical factors.

RESULTS: A total of 172 136 participants (mean [SD] age at BMI assessment 12.6 [4.4] years; mean [SD] age at cohort entry, 13.1 [4.4] years; 90 187 female [52.4%]) were included. Compared with participants with healthy weight, those with obesity had a 25.4% increased risk of PASC (RR, 1.25; 95% CI, 1.06-1.48) and those with severe obesity had a 42.1% increased risk of PASC (RR, 1.42; 95% CI, 1.25-1.61) when identified using the diagnostic code. Compared with those with healthy weight, there was an increased risk for any occurrences of PASC symptoms and conditions among those with obesity (RR, 1.11; 95% CI, 1.06-1.15) and severe obesity (RR, 1.17; 95% CI, 1.14-1.21), and the association held when assessing total incident occurrences among those with overweight (RR, 1.05; 95% CI, 1.00-1.11), obesity (RR, 1.13; 95% CI, 1.09-1.19), and severe obesity (RR, 1.18; 95% CI, 1.14-1.22).

CONCLUSIONS AND RELEVANCE: In this cohort study, elevated BMI was associated with a significantly increased PASC risk in a dose-dependent manner, highlighting the need for targeted care to prevent chronic conditions in at-risk children and young adults.

ABSTRACT

IMPORTANCE: Sexuality- and gender-diverse (SGD) young people experience substantial health disparities relative to cisgender heterosexual peers. Little is known about SGD adolescents younger than 15 years.

OBJECTIVE: To describe SGD prevalence and associated factors in a population-representative cohort of younger adolescents in Australia.

DESIGN, SETTING, AND PARTICIPANTS: This prospective cohort study was part of the Future Proofing Study, with enrollment of year 8 students at 134 Australian secondary schools from 2019 to 2021 and annual follow-ups for 5 years. Data were analyzed from June 20, 2023, to June 6, 2024.

MAIN OUTCOME AND MEASURES: Outcomes of interest were baseline self-reported gender and sexuality identities, individual characteristics, and mental health and disability diagnoses, as well as school characteristics.

RESULTS: Among 6388 participants, median (IQR) age was 13.9 (13.6-15.8), with a range of 10.7 to 17.5 years. Most participants attended school in a major city (76.0%), were born in Australia (91.4%), and spoke English at home (93.7%). Approximately half (3122 participants; 48.9% [95% CI, 45.2%-59.0%]) identified as female or girls, and 46.5% (2973 participants; 95% CI, 39.8%-53.4%) identified as male or boys. The overall proportion of transgender identity was 3.3% (95% CI, 2.7%-3.9%), with 23 participants (0.4%) identifying as transgender boys, 10 participants (0.2%) identifying as transgender girls, 117 participants (1.8%) identifying as transgender nonbinary, and 59 participants (0.9%) identifying as another transgender identity. The overall proportion of sexuality diversity was 12.0% (95% CI, 10.4%-13.8%). The proportion of cisgender participants who were sexuality-diverse (13.0% [95% CI, 11.4%-14.8%] of girls and 4.7% [95% CI, 3.7%-5.9%] of boys) was lower than the proportion among gender-diverse participants, which ranged from 30.0% (95% CI, 9.3%-64.1%) of transgender girls to 91.5% (95% CI, 81.3%-96.4%) of those with another diverse gender identity. Gender diversity and sexuality diversity were strongly associated (odds ratio [OR], 66.24; 95% CI, 38.23-114.80), and both were negatively associated with age (gender diversity: OR per 1-year older, 0.61; 95% CI, 0.49-0.76; sexuality diversity: OR per 1-year older, 0.78; 95% CI, 0.65-0.93) and positively with mental health diagnosis (gender diversity: OR, 2.41; 95% CI, 1.79-3.24; sexuality diversity: OR, 2.50; 95% CI, 2.10-2.98), and disability diagnosis (gender diversity: OR, 2.39; 95% CI, 1.68-3.40; sexuality diversity: OR, 1.96; 95% CI, 1.64-2.36). While there were significant associations between individual and school characteristics and responses to gender and sexuality identity items, patterns of association differed, with no consistent association with economic disadvantage.

CONCLUSIONS AND RELEVANCE: This cohort study of young adolescents found higher rates of SGD than among samples of older adolescents. The significant associations with younger age, poorer mental health, and disability underscored the urgent need for inclusive programs to promote a safe and welcoming environment in schools, health care settings, and communities.

ABSTRACT

IMPORTANCE: Currently, there are no treatments for nocturnal leg cramps (NLCs) that have been proven to be both safe and effective. Seeking safe and effective approaches for managing NLCs is of crucial importance.

OBJECTIVE: To determine whether vitamin K2 is better than placebo in managing NLCs.

DESIGN, SETTING, AND PARTICIPANTS: This multicenter, double-blind, placebo-controlled randomized clinical trial was conducted in China between September 2022 and December 2023. This study used a volunteer sample comprising community-dwelling individuals 65 years and older with 2 or more documented episodes of NLCs during 2 weeks of screening. Researchers performed a history and physical screening of candidates recruited from the community through advertisements, and eligible participants were randomized in a 1:1 ratio to receive vitamin K2 or a placebo for 8 weeks.

INTERVENTIONS: Patients orally took capsules containing either vitamin K2 (menaquinone 7), 180 μg, or a similar-looking placebo every day for 8 weeks. The study products were custom manufactured to have identical packaging and for the capsules to have matching appearance and identical excipients that shared similar taste and weight.

MAIN OUTCOMES AND MEASURES: The primary outcome was the mean number of NLCs per week between the vitamin K2 and the placebo group. Secondary outcomes included the duration of muscle cramps measured in minutes and the severity of muscle cramps assessed using an analog scale ranging from 1 to 10.

RESULTS: Among the 310 participants, 111 participants were excluded. Of the 199 enrolled individuals, 108 (54.3%) were female, and the mean (SD) age was 72.3 (5.5) years. A total of 103 patients (51.8%) were randomly assigned to receive vitamin K2 and 96 (48.2%) were assigned to placebo. The mean (SD) baseline weekly frequency of cramps was comparable in both the vitamin K2 group (2.60 [0.81]) and the placebo group (2.71 [0.80]). During the 8-week intervention, the vitamin K2 group experienced a reduction in the mean (SD) weekly frequency of cramps to 0.96 (1.41). Meanwhile, the placebo group maintained mean (SD) weekly frequency of cramps at 3.63 (2.20). The between-group difference was statistically significant (difference, -2.67; 95% CI, -2.86 to -2.49; P < .001). The vitamin K2 group had a more significant mean (SD) reduction in NLC severity (-2.55 [2.12] points) compared with the placebo group (-1.24 [1.16] points). The vitamin K2 group exhibited a more pronounced mean (SD) decrease in the duration of NLCs (-0.90 [0.88] minutes) than the placebo group (-0.32 [0.78] minutes). No adverse events related to vitamin K2 use were identified.

CONCLUSIONS AND RELEVANCE: This randomized clinical trial showed that vitamin K2 supplementation significantly reduced the frequency, intensity, and duration of NLCs in an older population with good safety.

ABSTRACT

IMPORTANCE: Approximately 50% of clinicians experience excessive emotional, physical, and mental stress, with repercussions across the entire medical system. Mindfulness exercises may mitigate this excessive stress. Heart rate variability (HRV) is an objective stress measure that can quantify which mindfulness exercises provide the greatest stress reduction.

OBJECTIVES: To define the impact of specific mindfulness exercises on HRV, a surrogate for physiologic stress, and the relationship between physiologic (HRV) and subjective stress measured by the State-Trait Anxiety Inventory during a one-day mindfulness workshop.

DESIGN, SETTING, AND PARTICIPANTS: This was a prospective observational pilot study performed at a quaternary children’s hospital with diverse subspecialists of pediatric nurses, nurse practitioners, and physicians.

MAIN OUTCOMES AND MEASURES: Our primary outcome measure was change in HRV from baseline during three mindfulness exercises.

RESULTS: The grounding, deep breathing, and body scan exercises all produced statistically significant changes in HRV among our 13 female participants. The body scan exercise produced statistically significant changes in all studied HRV parameters compared with baseline. We observed significant increases in Root Mean Square of Successive Differences between normal heartbeats (p = 0.026), high frequency (p ≤ 0.001), and the parasympathetic nervous system index (p ≤ 0.001) reflecting increased parasympathetic tone (e.g., relaxation), whereas sd 2/sd 1 ratio (p ≤ 0.001) and the stress index (p = 0.004) were decreased reflecting sympathetic withdrawal (e.g., decreased stress). Subjective stress decreased after 1-day mindfulness training (44.6 to 27.2) (p < 0.001). Individuals with the largest decrease in subjective stress also had the most improvement in HRV during the body scan exercise.

CONCLUSIONS: Clinician stress levels (HRV) improved after participating in grounding, deep breathing, and body scan meditations, which may highlight their importance as stress reduction tools for clinicians. Monitoring of HRV during mindfulness exercises may provide deeper understanding of which specific exercises produce the greatest physiologic stress reduction for individual participants and the trend of these changes over time.

ABSTRACT

OBJECTIVES/PURPOSES OF THE STUDY: The purpose of this study is to evaluate the content, delivery, and quality of medical information for vulvar lichen sclerosus on the social media platform TikTok.

MATERIALS AND METHODS: This is a descriptive, cross-sectional study. Using the third-party data scraping tool Apify, TikTok videos tagged with #lichensclerosus or “lichen sclerosus” were identified and sorted by view count. A sample of 100 videos was reviewed by 2 independent reviewers, excluding those not discussing lichen sclerosus. Videos were assessed using a coding document, the Patient Educational Materials Assessment Tool, and the DISCERN instrument. Interrater reliability was measured, and statistical analyses included Fleiss’ kappa, intraclass correlation coefficient, t tests, and Wilcoxon rank sum test with Holm-Bonferroni correction.

RESULTS: Content creators included patients (46%), health care professionals (30%), and others. Topics focused on clinical disease (52%) and treatment (48%). Evidence-based medicine was discussed in 71.7% of treatment-related videos, while 51.7% included nonevidence-based approaches, with a neutral or positive sentiment. Videos discussing topical steroids often had negative sentiments. Quality assessment revealed 61% of videos were understandable, 27% actionable, and 46% contained misinformation. Videos by health care professionals had less misinformation and higher quality scores compared to patient-generated content. Commercially biased videos were more understandable but contained more misinformation.

CONCLUSIONS: TikTok serves as a significant platform for sharing information on lichen sclerosus, but nearly half of the content contains misinformation. Health care professionals need to engage in social media to provide accurate information and counteract misinformation. Enhanced collaboration with patient advocates and careful resource sharing can improve the quality and reliability of medical information available online.

ABSTRACT

PURPOSE: The purpose of the study was to examine the characteristics and the influential effect of individual and social contextual factors on health information literacy among Chinese patients with type 2 diabetes coexisting with metabolic syndrome.

METHODS: Following convenience sampling, a total of 225 patients with type 2 diabetes coexisting with metabolic syndrome were recruited from a tertiary hospital in a suburban area of Beijing, China. Participants’ information was gathered through a set of self-reported questionnaires. Descriptive statistics, normality test, correlational analysis, univariate analysis, multiple linear regression, and logistic regression analysis were adopted to examine the potential factors of personal and social contextual resource related to health information literacy based on the health empowerment theory.

RESULTS: The health information literacy in this current sample was limited, with a mean score of 16.83 ± 2.96. Correlational analysis showed that self-management knowledge, attitude, and practice for metabolic syndrome; self-efficacy; health problem-solving; resilience; and chronic illness resources were significantly and positively related to health information literacy. Logistic regression analysis showed that self-management knowledge, health problem-solving, and the chronic illness resources were significantly correlated with health information literacy after controlling covariates.

CONCLUSIONS: Overall, the health information literacy among Chinese patients with type 2 diabetes coexisting with metabolic syndrome is suboptimal. Study findings demonstrated that personal and social contextual resources factors are significantly related to health information literacy. Health care professionals should consider strategies to enhance people’s health information literacy level and promote individuals’ health problem-solving, enhance chronic illness resources, and improve self-management knowledge when developing tailored interventions.

ABSTRACT

Assessment of executive and visuospatial neurocognitive domains is lacking in the Omani population, especially for elderly individuals with low educational levels. Therefore, the Towers of Kuwait-Arabic Neurocognitive Assessment (ToK-ArNA) was developed using similar psychometric features of Tower of London (ToL) test, and the unique architecture of Towers of Kuwait, with the potential to overcome the limitation of ToL color perception difficulties that might be encountered in subjects with hereditary or acquired color vision disorders. We enrolled 120 older Arabic-speaking Omanis from January 2022 to November 2022 and all participants underwent screening to ensure normal cognitive function before performing the ToL and ToK-ArNA tests. Validity, reliability, and non-parametric statistical tests were used for data analysis. A total of 85 participants, 51 men (60%) and 34 women (40%) met the inclusion criteria and completed the testing. Statistical analyses confirmed the validity and reliability of ToK-ArNA compared to ToL, with comparable total Time and Accuracy scores and more preference towered the ToK-ArNA among the participants. Despite the study limitations, these results indicate that the ToK-ArNA is a reliable and applicable executive and visuospatial function assessment tool and further studies are warranted to establish its validity in patients with various neurocognitive disorders.
