A Preliminary Analysis of the Acceptability and Feasibility of Biofeedback-Assisted Relaxation Delivered by Physical Therapists for Patients with Migraine (P7-12.002)

Neurology. 2025 Apr 8;104(7_Supplement_1):4224. doi: 10.1212/WNL.0000000000211532. Epub 2025 Apr 7.

ABSTRACT

OBJECTIVE: To conduct interim analyses to assess the feasibility, acceptability, and preliminary impact of a 6-session, in-person, PT-delivered BAR program for patients with migraine.

BACKGROUND: There are accessibility barriers to biofeedback-assisted relaxation (BAR), a Grade A evidence-based migraine preventive treatment, typically delivered by psychologists. Despite having BAR training for other conditions, physical therapists (PTs) do not traditionally deliver BAR for migraine.

DESIGN/METHODS: We conducted a randomized, single-blinded parallel study comparing BAR to Enhanced Usual Care (EUC) in patients with migraine. Between in-person sessions, participants were asked to practice daily. EUC participants were given educational handouts. Both groups completed a daily electronic headache diary. Outcome measures included migraine-related quality of life (MSQv2) and migraine-related disability (MIDAS).

RESULTS: Fifty participants enrolled (BAR=25, EUC=25). The majority (81.0%, 17/21 BAR; 79.2%, 19/24 EUC) agreed/strongly agreed that the electronic headache diary was easy to understand. BAR feasibility data (n=19) showed 89.5% attended 4+ sessions. BAR practice data (n=18) showed 66.7% reported daily practice, and 55.6% reported 10+ minutes of practice/session. Although not statistically significant, the BAR group had greater improvements in each MSQv2 subdomain compared to EUC (Role Function-Restrictive BAR=14.2 vs EUC=6.0, Role Function Preventive BAR=8.3 vs EUC=4.8, Emotional Function BAR=16.8 vs EUC=14.2). The BAR group had a greater mean change in MIDAS compared to EUC (-27.4 + 31.5 vs -5.48 + 22.0; P=0.010).

CONCLUSIONS: Of the patients with migraine who did PT-delivered BAR, the majority practiced daily (up to 10+ minutes/day), and there were clinically significant improvements in migraine-related disability compared to EUC.

Rates of Discontinuation and Nonpublication in Glioma Clinical Trials (P3-6.002)

Neurology. 2025 Apr 8;104(7_Supplement_1):4223. doi: 10.1212/WNL.0000000000211531. Epub 2025 Apr 7.

ABSTRACT

OBJECTIVE: This study aims to analyze the rates of discontinuation and nonpublication in clinical trials related to gliomas, highlighting factors that contribute to these issues.

BACKGROUND: Gliomas are complex tumors that present significant challenges in research and treatment. Despite numerous clinical trials, a substantial number are discontinued or unpublished, impacting the overall knowledge base and treatment strategies for glioma patients.

DESIGN/METHODS: We conducted a comprehensive analysis using data extracted from the ClinicalTrials.gov database. A total of 1,441 trials were identified and categorized based on their completion and publication status. We examined various trial characteristics, including participant demographics, enrollment size, study design, and funding sources. Statistical regression models were employed to identify predictors of trial discontinuation and nonpublication.

RESULTS: Among the identified trials, 1,092 (75.8%) were completed, while 349 (24.2%) were discontinued. Of the completed trials, 641 (44.5%) were published. Larger enrollment sizes and multi-center designs significantly reduced the likelihood of discontinuation (Odds Ratio [OR] = 0.215; p < 0.001) and nonpublication (OR = 0.481; p < 0.001).

CONCLUSIONS: The high rates of discontinuation and nonpublication in glioma trials underscore the need for improved research methodologies. Focusing on larger, multi-center collaborations could enhance trial completion and publication rates, ultimately benefiting glioma research and patient outcomes.

The Combined Impact of Intravenous Thrombolysis and Transfer Strategy on Endovascular Thrombectomy Outcomes for Vertebrobasilar Artery Occlusions (P12-13.001)

Neurology. 2025 Apr 8;104(7_Supplement_1):4239. doi: 10.1212/WNL.0000000000211541. Epub 2025 Apr 7.

ABSTRACT

OBJECTIVE: To investigate the interaction between intravenous thrombolysis (IVT) and transfer strategies (mothership vs. transfer) on outcomes following endovascular thrombectomy (EVT) for vertebrobasilar artery occlusions (VBAOs).

BACKGROUND: EVT has become a standard intervention for acute ischemic stroke caused by VBAOs.

DESIGN/METHODS: A retrospective analysis was conducted on VBAO patients who underwent EVT. Patients were categorized based on treatment type: IVT followed by EVT or EVT alone. Transfer strategies were classified as mothership or transfer. The primary outcomes were modified Rankin Scale (mRS≤3) and mortality at 90 days.

RESULTS: Among 175 patients, the median age was 67 years with 54.9% males. Among these, 33 patients (18.9%) received IVT before EVT, while 142 (81.1%) underwent EVT alone. Among all patients, 48 (27.4%) presented as mothership, and 127 (72.6%) were transfers. In bridging IVT cohort, mRS≤ 3 at 90 days was observed in 58.3% of the mothership group, a higher rate compared to 38.9% in the transfer group. For EVT alone cohort, the mothership group demonstrated a lower rate of mRS≤ 3 at 90 days (35.3%) compared to transfer (45.8%). The mothership group in the IVT cohort had a 90-day mortality rate of 41.7% compared to 50.0% in the transfer group, while for patients undergoing EVT alone, the mothership group had a mortality rate of 52.9% versus 43.8% in the transfer group. Interaction analysis indicated that the mothership strategy may have more pronounced benefits for IVT-refractory patients; however, the overall interaction effect was not statistically significant (p>0.05).

CONCLUSIONS: In patients with VBAOs undergoing EVT, bridging IVT showed better clinical outcomes in the mothership group compared to those transferred from outside hospitals, particularly in contrast to the EVT-alone group. These findings suggest that the mothership strategy may benefit patients who are potentially IVT-refractory. Further studies with larger sample sizes are needed to confirm these results.

Incidence and Neuropsychological Profile of Adult Attention Deficit Hyperactivity Disorder (ADHD) in Incarcerated Populations (P6-3.015)

Neurology. 2025 Apr 8;104(7_Supplement_1):4246. doi: 10.1212/WNL.0000000000211546. Epub 2025 Apr 7.

ABSTRACT

OBJECTIVE: Determine the annual crude incidence rate, the specific incidence rates by sex and age, and the age-standardized rates according to the latest National Population Census of Argentina (CNPA) from the year 2022, for diagnosed ADHD.

BACKGROUND: ADHD is common in childhood and adolescence, but it persists into adulthood in most cases, even without a prior diagnosis.

DESIGN/METHODS: A retrospective observational study was conducted, analyzing 42 patients between the ages of 16 and 65, who were evaluated between June 2022 and July 2024. Crude annual incidence rates, sex- and age-specific incidence rates, and rates standardized according to the 2022 National Population Census of Argentina (CNPA) were calculated, along with sociodemographic characteristics and results from self-administered questionnaires and neuropsychological tests.

RESULTS: The crude annual incidence rate of ADHD was 74.8 per 100,000 inhabitants/year (95% CI: 6.25-19.1), 65 per 100,000 in men (95% CI: 7.2-33.1), and 83 per 100,000 in women (95% CI: 3.4-17.2). The rate adjusted to the CNPA was 5.8 cases per 100,000 inhabitants/year. The mean age at diagnosis was 33.80 years (SD 13.22), with the most frequent subtype being inattentive (54.76%), followed by combined (35.71%) and hyperactive (4.76%). No significant sex differences were found among ADHD subtypes (p: 0.22). The majority of patients had incomplete university education (30.95%) and were employed (59.52%). The most common comorbidities were anxiety (90.48%) and depression (57.14%). Substance use affected 35.71% of patients, with marijuana being the predominant substance. Neuropsychological tests showed below-average Z-scores in IFS (-1.65, SD 1.23), TRAIL B (-1.43, SD 1.33), TRAIL A (-0.95, SD 1.3), PASAT 3 seconds (-1.29, SD 1.22), and IMO (-1.16, SD 0.84).

CONCLUSIONS: This work represents the first incidence study of ADHD in Argentina and shows a low crude annual incidence rate and census-adjusted rate compared to other recent studies conducted in different populations.

Condom use prevalence during the COVID-19 pandemic among female sex workers in Dakar, Senegal: a retrospective, cross-sectional analysis

Health Policy Plan. 2025 Apr 7:czaf023. doi: 10.1093/heapol/czaf023. Online ahead of print.

ABSTRACT

Literature suggests that individuals may trade off health for income in face of an economic shock. Being in a close contact profession, the livelihoods of sex workers were severely affected by the COVID-19 pandemic. Few studies exist on whether prevalence of better-renumerated condomless sex increased among this population in low and middle-income countries and discuss its implications on HIV/STI transmission especially during pandemic situations. We reported cross-sectional condom use prevalence estimates of 600 female sex workers in Dakar, Senegal from data collected before (2015, 2017) and during the pandemic (June-July 2020). Condom use prevalence was elicited via list experiments for more truthful estimates. Double list experiment estimates of mean condom use prevalence declined from 78.2 percent (95% CI: 70.9-85.5 percent) in 2017 to 65.1 percent (95% CI: 57.6-72.7 percent) in 2020. This statistically significant decrease of 13.1 percentage points (p=0.014) represents a 16.8 percent fall in condom use and a 60.2 percent increase in condomless sex prevalence. The fall in condom use prevalence was largely concentrated amongst the asset-poor, providing some suggestive evidence that economic reasons drove the fall in condom use, reinforcing findings in existing literature regarding the positive relationship between economic shocks and risky sexual behaviours. At the point of the survey, the observed decline in client numbers exceeded the reduction in condom use prevalence, suggesting potential mitigation of HIV/STI transmission risks during the COVID-19 pandemic; nevertheless, the lack of direct comparability between these two metrics warrants cautious interpretation. However, more accurate epidemiological modelling considering the non-sex worker population and longer-term studies on whether condom use prevalence returned to pre-COVID levels after client numbers recovered are required for a comprehensive assessment of the pandemic’s short-term and longer-term impact on HIV/STI transmission.

Comorbidity in Midlife and Cancer Outcomes

JAMA Netw Open. 2025 Apr 1;8(4):e253469. doi: 10.1001/jamanetworkopen.2025.3469.

ABSTRACT

IMPORTANCE: Comorbidities in midlife are common but how these conditions are associated with cancer outcomes is poorly understood.

OBJECTIVE: To investigate the association between different comorbidities and risk of incident cancer and cancer mortality.

DESIGN, SETTING, AND PARTICIPANTS: This cohort study is a secondary analysis of the prospective Prostate, Lung, Colorectal, and Ovarian (PLCO) screening trial conducted at 10 PLCO screening centers across the US. Participants included adults aged 55 to 74 years without a history of cancer enrolled between 1993 and 2001. Statistical analysis was performed from June 2023 to December 2024.

EXPOSURES: Self-reported history of 12 comorbid conditions classified into 5 distinct classifications guided by World Health Organization categorization.

MAIN OUTCOME AND MEASURES: Outcomes included risk of all cancers combined, risk of 19 individual cancer types, and cancer mortality. Multivariable Cox proportional hazards models were used to estimate the association between comorbidity classifications and cancer outcomes.

RESULTS: Among 128 999 participants included in the analysis, 330 (0.3%) were American Indian, 5414 (4.2%) were Asian or Pacific Islander, 6704 (5.2%) were non-Hispanic Black, and 114 073 (88.4%) were non-Hispanic White; 64 171 (49.7%) were male; and the median (IQR) age was 62 (58-66) years. After a median (IQR) follow-up of 20 (19-22) years, the risk of any incident cancer was significantly higher for individuals with a history of respiratory (hazard ratio [HR], 1.07 [95% CI, 1.02-1.12]) and cardiovascular conditions (HR, 1.02 [95% CI, 1.00-1.05]). History of each comorbid condition evaluated was significantly associated with incidence of at least 1 cancer type. The strongest association was between history of liver conditions and risk of liver cancer (HR, 5.57 [95% CI, 4.03-7.71]), whereas metabolic conditions (obesity or type 2 diabetes) were significantly associated with higher risk of 9 cancer types and lower risk of 4 cancer types. Respiratory (HR, 1.19 [95% CI, 1.11-1.28]), cardiovascular (HR, 1.08 [95% CI, 1.04-1.13]), and metabolic (HR, 1.09 [95% CI, 1.05-1.14]) conditions were positively associated with a higher hazard of cancer death.

CONCLUSIONS AND RELEVANCE: In this cohort study of 128 999 adults without a history of cancer, comorbidities in midlife were associated with the overall risk of cancer and more strongly associated with risk of multiple individual cancer types, with the direction of association differing across cancer types. These results may inform clinical management of patients at risk for cancer.

Zero Suicide Model Implementation and Suicide Attempt Rates in Outpatient Mental Health Care

JAMA Netw Open. 2025 Apr 1;8(4):e253721. doi: 10.1001/jamanetworkopen.2025.3721.

ABSTRACT

IMPORTANCE: Suicide is a major public health concern, and as most individuals have contact with health care practitioners before suicide, health systems are essential for suicide prevention. The Zero Suicide (ZS) model is the recommended approach for suicide prevention in health systems, but more evidence is needed to support its widespread adoption.

OBJECTIVE: To examine suicide attempt rates associated with implementation of the ZS model in outpatient mental health care within 6 US health systems.

DESIGN, SETTING, AND PARTICIPANTS: This quality improvement study with an interrupted time series design used data collected from January 2012 through December 2019, from patients aged 13 years or older who received mental health care at outpatient mental health specialty settings within 6 US health systems located in 5 states: California, Oregon, Washington, Colorado, and Michigan. Analyses were conducted from January through December 2024.

EXPOSURE: The ZS model was implemented in 4 health systems at different points during the observation period (2012-2019) and compared with health systems that implemented the model before the observation period (postimplementation). Implementation included suicide risk screening, assessment, brief intervention (safety plan, means safety protocol), and behavioral health treatment.

MAIN OUTCOMES AND MEASURES: The primary outcome was a measure of standardized monthly suicide attempt rates captured using health system records and government mortality records. Suicide death rates were also measured as a secondary outcome.

RESULTS: There was a median of 309 107 (range, 55 354-451 837) unique patients per month. In 2017, there were 317 939 eligible individuals (63.2% female). Baseline suicide attempt rates were at least 30 to 40 per 100 000 individuals at each implementation site and decreased to less than 30 per 100 000 individuals at 3 sites by 2019. Decreases in suicide attempt rates were observed at 3 intervention health systems after site-specific implementation: health systems A and B had decreases of 0.7 per 100 000 individuals per month and C, 0.1 per 100 000 individuals per month. System D evidenced a similar suicide attempt rate after implementation (before implementation: median rate: 35.0 [range, 11.0-50.3] per 100 000 patients per month; after implementation: median rate: 34.3 [range, 18.5-42.0] per 100 000 patients per month). The 2 postimplementation health systems maintained low or declining suicide attempt rates throughout the observation period. The rate at system Y decreased by 0.3 per 100 000 individuals per month across the observation period. The rate at system Z began at 11 per 100 000 individuals per month and declined by 0.03 per 100 000 individuals per month during the observation period. Two systems evidenced reductions in the suicide death rate after implementation: system B declined by 0.2 per 100 000 individuals per month and system C by 0.1 per 100 000 individuals per month.

CONCLUSIONS AND RELEVANCE: In this quality improvement study, ZS model implementation was associated with a reduction in suicide attempt rates among patients accessing outpatient mental health care at most study sites, which supports widespread efforts to implement the ZS model in these settings within US health systems.

Neighborhood Disadvantage, Individual Experiences of Racism, and Breast Cancer Survival

JAMA Netw Open. 2025 Apr 1;8(4):e253807. doi: 10.1001/jamanetworkopen.2025.3807.

ABSTRACT

IMPORTANCE: Due to the legacy of structural racism in the United States, Black US residents are more likely to live in disadvantaged neighborhoods regardless of individual socioeconomic status. Black women are also more likely to die from their breast cancer.

OBJECTIVE: To investigate whether neighborhood disadvantage and individual experiences of racism are associated with breast cancer mortality among Black US women.

DESIGN, SETTING, AND PARTICIPANTS: Prospective follow-up study conducted within the Black Women’s Health Study (BWHS), a nationwide cohort study of 59 000 self-identified Black females enrolled in 1995 and followed up by biennial questionnaires. BWHS participants diagnosed with breast cancer at stages I to III and who survived 12 months after initial diagnosis were included (n = 2290). Deaths and cause of death were identified through linkage with the National Death Index.

EXPOSURES: Geocoded participant addresses were linked with US Census Bureau and American Community Survey data to create neighborhood-level indices reflecting relative disadvantage. Data on experiences of racism were obtained from questionnaires.

MAIN OUTCOMES AND MEASURES: Breast cancer-specific and all-cause mortality. Hazard ratios (HRs) and 95% CIs were estimated from multivariable Cox proportional hazards regression models.

RESULTS: There were 305 breast cancer-specific deaths among 2290 women with invasive breast cancer (mean [SD] age at diagnosis, 56.7 [10.9] years) who were followed up for a median (IQR) of 10.5 (5.6-16.1) years. The mortality rate was 14.26 (95% CI, 11.01-17.51) per 1000 person-years for those living in the most disadvantaged neighborhoods and 8.82 (95% CI, 6.55-11.09) per 1000 person-years for those living in the least disadvantaged neighborhoods (HR, 1.47; 95% CI, 1.02-2.12). HRs for women living in areas of extreme economic deprivation (vs privilege) and for women who reported experiences of racism in at least 2 institutional spheres (vs none) were also greater than 1, but not statistically significant (extreme economic deprivation vs privilege: HR, 1.19; 95% CI, 0.88-1.61; racism in 2 spheres vs none: HR, 1.28; 95% CI, 0.96-1.73).

CONCLUSIONS AND RELEVANCE: In this cohort of Black women, living in disadvantaged neighborhoods was associated with a higher mortality from breast cancer, even after accounting for stage at diagnosis, treatments, and individual-level lifestyle factors. Community-level interventions to reduce environmental stressors and improve conditions in disadvantaged neighborhoods, including access to high-quality cancer care, may be critical to reducing racial disparities in breast cancer survival.

Perceived Contributors to Job Quality and Retention at Home Care Cooperatives

JAMA Netw Open. 2025 Apr 1;8(4):e254457. doi: 10.1001/jamanetworkopen.2025.4457.

ABSTRACT

IMPORTANCE: To safely age at home, millions of older adults rely on the services of home care workers (HCWs), a workforce marked by poor working conditions, high turnover, and critical worker shortages. Home care cooperatives-businesses co-owned and controlled by HCWs-have demonstrated significantly lower turnover and higher job quality than traditional home care businesses, but the factors associated with these outcomes have not been investigated.

OBJECTIVE: To identify potential factors associated with higher job quality and lower turnover at home care cooperatives.

DESIGN, SETTING, AND PARTICIPANTS: In this qualitative study, semistructured interviews were conducted in English from November 2023 to June 2024. To be eligible for the study, participants had to be 18 years old or older, speak English, and currently be employed by a home care cooperative. Interviews were conducted remotely over Zoom with individual HCWs and staff from home care cooperatives from across the US. Data were analyzed from May to July 2024.

EXPOSURE: Employment at a home care cooperative.

MAIN OUTCOMES AND MEASURES: Interviews were audio recorded and transcribed. A thematic analysis approach was used to code interviews and identify major themes and subthemes, informed by a conceptual model of direct care worker job outcomes.

RESULTS: A total of 23 HCWs and 9 staff members (14 participants aged 20-39 years [44%]; 8 [25%] African American, 4 [13%] Latinx, and 17 [53%] non-Latinx White) from 5 home care cooperatives participated in the study. Participants identified 4 key aspects of the cooperative work environment they perceived to be contributing to higher job quality and lower turnover compared with traditional agencies: (1) greater workplace control regarding patient care, case assignments, and organizational policies; (2) stronger community support and camaraderie; (3) a deeper culture of respect in which HCWs felt more valued; and (4) higher overall compensation in the form of wages, benefits, or profit sharing.

CONCLUSIONS AND RELEVANCE: In this qualitative study of HCWs and staff at home care cooperatives, participants perceived cooperatives’ relatively high levels of HCW control, community, respect, and compensation to be important contributors to HCWs’ retention in the field. The participatory structure and practices of home care cooperatives in these areas may represent novel approaches for home care agencies to reduce HCW turnover and improve job quality to address critical workforce shortages.

Impact of surgical approach and survival prediction of malignant phyllode tumor by machine learning

Updates Surg. 2025 Apr 7. doi: 10.1007/s13304-025-02191-4. Online ahead of print.

ABSTRACT

We aimed to analyze the effect of surgical approach on patients with malignant phyllode tumor of the breast (MPTB) and to develop a prognostic prediction model for patients with MPTB. We extracted MPTB patients aged 18-80 years between 2000 and 2020 from the SEER database. Covariable imbalance was reduced using the propensity-score matching (PSM) method. An analysis of Cox proportional hazard regression was performed to compare breast cancer-specific survival (BCSS) with overall survival (OS). The survival curves were generated using the Kaplan-Meier method. The 5-year BCSS and 5-year OS of patients with MPTB were predicted by ten models based on machine learning. According to multivariate Cox analysis, surgical treatment of MPTB does not affect long-term survival outcomes (p > 0.05). Among our study, the survival outcomes of mastectomy and BCS would not be statistically significant even for patients with poor pathologic type of MPTB (p > 0.05). In terms of AUC, CatBoost performed better than other algorithms with a 5-year BCSS of 0.8488 and a 5-year OS of 0.8512. BCS and mastectomy do not make a significant difference in the long-term survival outcomes of patients with MPTB. Therefore, we suggest that BCS is feasible and preferred provided that surgical margin requirements can be met. As a trusted model, CatBoost provides better guidance and support for the systemic treatment of patients with MPTB.
