RESUMO
HIV test counselors are well positioned to refer individuals to pre-exposure prophylaxis (PrEP) and behavioral health treatments. HIV test counselors in Miami-Dade County (N = 20), a priority jurisdiction for Ending the HIV Epidemic, completed interviews to assess determinants of PrEP and behavioral health treatment referrals. To identify determinants, we used a rapid deductive qualitative analysis approach and the Consolidated Framework for Implementation Research (CFIR). Identified determinants sometimes served as facilitators (e.g., relative priority, leadership importance) and sometimes as barriers (e.g., lack of access to knowledge and information, available resources for referrals) to making referrals. We also observed differences in determinants between PrEP and behavioral health referrals. For example, complexity (perceived difficulty of the referral) was a barrier to behavioral health more often than PrEP referral. Our findings suggest that determinants across many CFIR domains affect referral implementation, and the corresponding need for multiple implementation strategies to improve implementation of PrEP and behavioral health referrals in the context of HIV testing.

BACKGROUND: Facilitating access to HIV prevention and treatment is imperative in Miami-Dade County (MDC), a U.S. HIV epicenter. With COVID-19, disruptions to these services have occurred, leading HIV organizations to innovate and demonstrate resilience. This study documented COVID-19 related disruptions and resilient innovations in HIV services within MDC. METHODS: This mixed methods cross-sectional study included HIV test counselors in MDC. In the quantitative component (N=106), participants reported COVID-19 impacts on HIV service delivery. Data visualization examined patterns within organizations and throughout the study period. Generalized estimating equation modeling examined differences in service disruptions and innovations. In the qualitative component, participants (N=20) completed interviews regarding COVID-19 impacts on HIV services. Rapid qualitative analysis was employed to analyze interviews. RESULTS: Quantitative data showed that innovations generally matched or outpaced disruptions, demonstrating resilience on HIV service delivery during COVID-19. HIV testing (36%, 95%CI[28%, 46%]) and STI testing (42%, 95%CI[33%, 52%]) were most likely to be disrupted. Sexual/reproductive health (45%, 95%CI[35%, 55%]), HIV testing (57%, 95%CI[47%,66%]), HIV case management (51%, 95%CI[41%, 60%]), PrEP initiation (47%, 95%CI[37%,57%]), and STI testing (47%, 95%CI[37%, 57%]) were most likely to be innovated. Qualitative analysis revealed three orthogonal themes related to 1) disruptions (with five sub-components), 2) resilient innovations (with four sub-components), and 3) emerging and ongoing health disparities. CONCLUSIONS: HIV organizations faced service disruptions during COVID-19 while also meaningfully innovating. Our findings point to potential changes in policy and practice that could be maintained beyond the immediate impacts of COVID-19 to enhance the resilience of HIV services. Aligning with the US Ending the HIV Epidemic Plan and the National Strategy for HIV/AIDS, capitalizing on the observed innovations would facilitate improved HIV-related health services for people living in MDC and beyond.

Objectives: This longitudinal study aims at 1) providing preliminary evidence of changes in blood-based biomarkers across time in chronic TBI and 2) relating these changes to outcome measures and cerebral structure and activity.Methods: Eight patients with moderate-to-severe TBI (7 males, 35 ± 7.6 years old, 5 severe TBI, 17.52 ± 3.84 months post-injury) were evaluated at monthly intervals across 6 time-points using: a) Blood-based biomarkers (GFAP, NSE, S100A12, SDBP145, UCH-L1, T-tau, P-tau, P-tau/T-tau ratio); b) Magnetic Resonance Imaging to evaluate changes in brain structure; c) Resting-state electroencephalograms to evaluate changes in brain function; and d) Outcome measures to assess cognition, emotion, and functional recovery (MOCA, RBANS, BDI-II, and DRS).Results: Changes in P-tau levels were found across time [p = .007]. P-tau was positively related to functional [p < .001] and cognitive [p = .006] outcomes, and negatively related to the severity of depression, 6 months later [R = -0.901; p =.006]. P-tau and P-tau/T-tau ratio were also positively correlated to shape change in subcortical areas such as brainstem [T(7) = 4.71, p = .008] and putamen [T(7) = 3.25, p = .012].Conclusions: Our study provides preliminary findings that suggest a positive relationship between P-tau and the recovery of patients with chronic TBI.

OBJECTIVES: Guided by a racial microaggression framework and utilizing a mixed-method approach, this study explores multiracial individuals' interpersonal experiences and perceptions of racial identification inquiries--queries directed toward them as others attempt to determine their racial background (e.g., "What are you?"). METHODS: As part of an online study, multiracial college students (n = 40) were presented with a hypothetical situation in which racial identification inquiries were delivered by a White, racial minority, or racially unspecified communicator. Qualitative analyses identified the categories and thematic codes of participants' open-ended explanations of the personal relevance of these hypothetical situations and proposed endings. Nonparametric tests examined differences in situation, affect, and communication partner ratings based on race of the communicator. RESULTS: Findings affirmed that racial identification inquiries are commonly reported by diverse multiracial individuals (92.5% of the present sample). Qualitative coding of participants' explanations of personal relevance and proposed endings for the hypothetical situations, as well as ratings of situation, affect, and communication partner, revealed both positive and negative characterizations ascribed to racial identification inquiry experiences. Participants who imagined the queries came from a White communicator allotted less time to continuing the conversation than those in the control condition (communicator race unspecified). CONCLUSIONS: A racial microaggression framework was relevant but not sufficient in reflecting the complex nature of racial identification inquiries for multiracial individuals. The insights into multiracial individuals' perceptions of these stimuli encourage more critical and dynamic thinking about racial categorization systems and interpersonal racial processes for this underrepresented but growing population.

OBJECTIVES: To evaluate and synthesize research findings on adverse birth outcomes and maternal morbidity among Afro-Latinas and their infants. METHODS: A systematic review was conducted within PubMed, Web of Science, and SCOPUS databases. Four thousand five hundred twenty-six published peer-reviewed articles from 1970 to 2023 that reported outcomes related to maternal morbidity and/or birth outcomes were screened. After screening, we assessed 22 for eligibility, and ultimately, seven studies were included for data extraction and analysis. RESULTS: Although limited, the existing studies revealed disparities in abnormal birth weight (LBW & SGA) and higher preterm birth prevalence among Afro-Latinas compared to other racial and ethnic peers. These disparities are also prevalent among U.S.-born Afro-Latinas compared to foreign-born Afro-Latinas. CONCLUSIONS: By critically examining the current empirical evidence, we can gain a deeper understanding of how intersectionality impacts perinatal health outcomes among Afro-Latinas. Understanding the root causes of these outcomes through increased research is critical to preventing and reducing poor maternal and child health among Afro-Latinas, particularly those who are U.S.-born.
RESUMO
PURPOSE: The purpose of this study is to refine and establish measures of multilevel barriers and facilitators to HIV testing and PrEP for Latino sexual minority men (LSMM). DESIGN: Cross-sectional measure validation. SETTING: Participants from Miami, FL. SUBJECTS: 290 LSMM from the DÍMELO study. MEASURES: Based on prior qualitative work, we developed two measures that evaluated multiple determinants (i.e., barriers and facilitators) to (1) HIV testing and (2) PrEP use. ANALYSIS: All measures included in this analysis assessed a set of theoretically distinct barriers and facilitators. We performed 11 exploratory factor analyses (EFA) to assess the dimensionality of theoretical groupings of items informed by prior qualitative work, including: knowledge, perceived need and benefit, mistrust and concerns, stigma and normalization, cultural competence, navigation support, provider demeanor, clinic and medical system issues, privacy concerns, cost, and language and immigration barriers. Based on EFA results, we conducted two confirmatory factor analyses (CFA), one for each measure. RESULTS: Within each measure, the 11 EFAs extracted 10 barrier factors and 7 facilitator factors. The CFAs for HIV testing and PrEP measures were consistent, such that all models retained the structures identified in the EFAs. CONCLUSION: Findings support the use of these measures with LSMM. These measures can inform multilevel implementation strategies for health promotion professionals to scale up and disseminate HIV prevention services to LSMM.

Growing cannabis use among young adults in the United States surpasses research and public understanding, raising health concerns despite potential benefits. Limited research focuses on their knowledge, attitudes, risks, and motivations, especially in states with limited legalization. This study explores cannabis knowledge and attitudes among healthy young adult cannabis consumers to understand their risk and benefit perceptions. Data include a subsample of participants in the Herbal Heart Study, a cohort to examine subclinical cardiovascular risk among healthy young adult (18-35 years old) cannabis consumers and non-consumers. A qualitative thematic analysis of the interviews was performed using a deductive approach driven by the theory of the Health Belief Model to generate categories and codes. Dedoose was used to organize transcripts and coding. A total of 22 young adult cannabis consumers (M age = 25.3, SD = 4.4) were interviewed between May 5, 2021- September 23, 2022. Participants were predominantly female (n = 13) and Hispanic (n = 9) or non-Hispanic Black (n = 7). Five themes were identified: perceived health benefits and risks associated with cannabis use, motivation for cannabis use, knowledge of cannabis, and perceived barriers to cannabis use. Participants discussed knowledge, positive/negative attitudes toward cannabis, and perceived risks/benefits based on personal experience and gathered information. Some showed knowledge deficits, and most wanted more health-related cannabis research. Given the current climate of rising cannabis legalization, availability of novel cannabis products, and societal acceptance, further research and evidence-based cannabis literacy for young adults are essential to keep pace with liberalization trends.
RESUMO
Objectives: This sequential explanatory mixed-method study aimed to explore chiropractic students' attitudes toward incorporating maintenance care (MC) focused evidence. Methods: Attitudes towards using an evidence-based clinical protocol for maintenance care (MC), the MAINTAIN instrument, were assessed via surveys, monologue responses, dialogues, and qualitative feedback. Participants from a single chiropractic educational institution completed questionnaires evaluating their perspectives on patient-centeredness, chronic pain, and evidence incorporation. Descriptive statistics summarized quantitative data, while content analysis was used for qualitative data. Results: 74.4% (n=419) of students participated, mostly male (57.5%), with an average GPA of 3.15 (out of a maximum of 4.0). Qualitative analysis identified the need to clarify MC terminology and factors motivating students to adopt new evidence, such as quality and alignment with healthcare beliefs. Conclusions: This study's findings emphasize the importance of refining healthcare training strategies, including defining terminology and addressing motivators for evidence incorporation, as evidence for MC for low back pain evolves.

Résultats: 74,4 % (n=419) des étudiants ont participé à l'étude, principalement des hommes (57,5 %), avec une moyenne de 3,15 (sur un maximum de 4,0). L'analyse qualitative a permis de déterminer la nécessité de clarifier la terminologie des SE et des facteurs qui incitent les élèves à adopter de nouvelles données probantes, comme la qualité et l'harmonisation avec les croyances en matière de soins de santé. Conclusions: Les conclusions de cette étude soulignent l'importance de peaufiner les stratégies de formation en soins de santé, notamment en définissant la terminologie et en répondant aux motivations pour l'incorporation de données probantes, à mesure que les preuves concernant les SE pour les lombalgies évoluent.
RESUMO
This study resulted in the identification of pectinolytic yeasts in directly brined Sicilian-style green olive fermentations and examination of the influence of those yeasts on the microbial composition and quality of fermented olives. Firstly, defective olives processed in Northern California from 2007 to 2008 and characterized by high levels of mesocarp tissue degradation were found to contain distinct yeast and bacterial populations according to DNA sequence-based analyses. Strains of (pectinolytic) Saccharomyces cerevisiae, Pichia manshurica, Pichia kudriavzevii, and Candida boidinii isolated from directly brined olives were then inoculated into laboratory-scale olive fermentations to quantify the effects of individual yeast strains on the olives. The pH, titratable acidity, and numbers of lactic acid bacteria (LAB) and yeasts varied between the fermentations and fermentations inoculated with P. kudriavzevii and C. boidinii promoted the development of LAB populations. Olive tissue structural integrity declined significantly within 30, 74, and 192 days after the inoculation of pectinolytic S. cerevisiae, P. manshurica and C. boidinii, respectively. In comparison, tissue integrity of olives in control fermentations remained intact although pectinolytic yeasts were present. Notably, pectinolytic yeasts were not found in fermentations inoculated with (non-pectinolytic) P. kudriavzevii and olives exposed to a 1:1 ratio of P. kudriavzevii and P. manshurica exhibited no significant tissue defects. This study showed that pectinolytic yeast are important components of directly brined green olive fermentations and damage caused by pectinolytic yeasts might be prevented by other microbial colonists of the olives.

OBJECTIVE: This study investigated early, real-world outcomes with cenobamate (CNB) in a large series of patients with highly drug-resistant epilepsy within a Spanish Expanded Access Program (EAP). METHOD: This was a multicenter, retrospective, observational study in 14 hospitals. Inclusion criteria were age ≥18 years, focal seizures, and EAP authorization. Data were sourced from patient clinical records. Primary effectiveness endpoints included reductions (100%, ≥90%, ≥75%, and ≥50%) or worsening in seizure frequency at 3-, 6-, and 12-month visits and at the last visit. Safety endpoints included rates of adverse events (AEs) and AEs leading to discontinuation. RESULTS: The study included 170 patients. At baseline, median epilepsy duration was 26 years and median number of seizures/month was 11.3. The median number of prior antiseizure medications (ASMs) and concomitant ASMs were 12 and 3, respectively. Mean CNB dosages/day were 176 mg, 200 mg, and 250 mg at 3, 6, and 12 months. Retention rates were 98.2%, 94.5%, and 87% at 3, 6, and 12 months. At last available visit, the rate of seizure freedom was 13.3%; ≥90%, ≥75%, and ≥50% responder rates were 27.9%, 45.5%, and 63%, respectively. There was a significant reduction in the number of seizures per month (mean: 44.6%; median: 66.7%) between baseline and the last visit (P < 0.001). Responses were maintained regardless of the number of prior or concomitant ASMs. The number of concomitant ASMs was reduced in 44.7% of patients. The cumulative percentage of patients with AEs and AEs leading to discontinuation were 68.2% and 3.5% at 3 months, 74.1% and 4.1% at 6 months, and 74.1% and 4.1% at 12 months. The most frequent AEs were somnolence and dizziness. SIGNIFICANCE: In this highly refractory population, CNB showed a high response regardless of prior and concomitant ASMs. AEs were frequent but mostly mild-to-moderate, and few led to discontinuation.

BACKGROUND: Nearly 5 % of pregnant women in the United States use cannabis. However, expecting mothers often do not seek counsel from their healthcare providers about prenatal cannabis use due to stigma and legal ramifications. Instead, cannabis-using pregnant women turn to each other to learn. Online message boards have become a safe place for parents to seek answers anonymously in real-time. The objective of this study was to examine the information-seeking/giving behaviors of cannabis-using pregnant women on an online community forum. METHODS: We extracted 151 original messages and 1260 corresponding comments posted over a 7-day period from Whattoexpect.com's "Ganja Mamas" forum. We iteratively developed a codebook with 16 categories to reflect information-seeking behavior. N = 131 unique forum members posted questions for comment. RESULTS: Approximately half, 46.56 %, reported their geographic location (24 states), and 40.46 % reported gestational age. The top topics for which members sought out information were testing, state-specific questions, postpartum, child protective services (CPS), hospital-specific questions, birth announcements, methods of cannabis use, quitting, breastfeeding/pumping, pregnancy symptoms, mental health, general health and pregnancy, and quantity of cannabis use. The second phase of analysis was based on members' responses. Clustered codes indicated how the respondents were using the forum: (1) interviewing and geographic location, (2) knowledge, experience, and reassurance, (3) congratulations and relief, and (4) concealing cannabis use and symptoms. CONCLUSIONS: Our results demonstrate that mothers on an online cannabis forum are seeking information about location-specific experiences pertaining mostly to testing and child protective services. Additionally, mothers are responding by geographic-specific interviewing, and are expressing relief and reassurance in response to members' experiences.

Background: Patient-centred care is internationally recognized as a foundation of quality patient care. Attitudes of students towards patient-centred care have been assessed in various health professions. However, little is known how chiropractic students' attitudes towards patient-centred care compare to those of other health professions or whether they vary internationally, and between academic programs. Objective: To assess the association of select variables on student attitude towards patient-centred care among select chiropractic programs worldwide. Methods: We conducted a cross-sectional study using the Patient-Practitioner Orientation Scale (PPOS) to assess students' patient-centred attitudes towards the doctor-patient relationship. Eighteen items were scored on a 1 to 6 Likert scale; higher scores indicating more patient-centredness. All students from seven chiropractic educational programs worldwide were invited to complete an online survey. Results were analyzed descriptively and inferentially for overall, sharing and caring subscales. General linear regression models were used to assess the association of various factors with PPOS scores. Results: There were 1858 respondents (48.9% response rate). Student average age was 24.7 (range = 17-58) years and 56.2% were female. The average overall PPOS score was 4.18 (SD = 0.48) and average sharing and caring subscale scores were 3.89 (SD = 0.64) and 4.48 (SD = 0.52), respectively. There were small but significant differences in all PPOS scores by gender, age, and program. Year/semester of study within a program typically was not associated with scores, neither was history of previous chiropractic care nor having family members who are health professionals. Conclusion: This is the first international study assessing students' attitudes of patient-centred care in chiropractic educational programs. We found small but significantly different PPOS scores between chiropractic programs worldwide that did not change across year/semester of study. Scores tended to be lower than those reported among medical students. Observed differences may be related to curricular content, extent of patient exposure and/or regional cultural realities.

RESUMO
BACKGROUND: Asthma exacerbations are a leading cause of hospitalization among children. Despite the existence of national pediatric asthma guidelines, significant variation in care persists. At Duke Children's Hospital, we determined that our average length of stay (ALOS) and cost for pediatric asthma admissions exceeded that of our peers. Our aim was to reduce the ALOS of pediatric patients hospitalized with asthma from 2.9 days to 2.6 days within 12 months by implementing an asthma pathway within our new electronic health record. METHODS: We convened a multidisciplinary committee charged with reducing variability in practice, ALOS, and cost of inpatient pediatric asthma care, while adhering to evidence-based guidelines. Interventions were tested through multiple "plan-do-study-act" cycles. Control charts of the ALOS were constructed and annotated with interventions, including testing of an asthma score, implementation of order sets, use of a respiratory therapy-driven albuterol treatment protocol, and provision of targeted education. Order set usage was audited as a process measure. Readmission rates were monitored as a balancing measure. RESULTS: The ALOS of pediatric patients hospitalized with asthma decreased significantly from 2.9 days to 2.3 days. Comparing baseline with intervention variable direct cost data revealed a savings of $1543 per case. Improvements occurred in the context of high compliance with the asthma pathway order sets. Readmission rates remained stable throughout the study period. CONCLUSIONS: Implementation of an asthma care pathway based on the electronic health record improved the efficiency and variable direct costs of hospital care, reduced variability in practice, and ensured adherence to high-quality national guidelines.

RESUMEN Objetivos: Conocer la diversidad genética de Aedes aegypti en el corredor vial transfronterizo Central-Alto Paraná de Paraguay, con registros de casos de dengue. Materiales y métodos: Se seleccionaron veinte hembras adultas de la eclosión de huevos de Ae. aegypti procedentes de casas geolocalizadas en los departamentos de Alto Paraná, Caaguazú, Cordillera y Central, entre el 2018 y 2019. Se extrajo ADN del tejido de las hembras para amplificación aleatoria de sus patrones polimórficos mediante amplificación aleatoria del ADN polimórfico por PCR (RAPD-PCR), usando cebadores H3 y B03 a fin de conocer parámetros genéticos de diversidad poblacional. Las relaciones entre las poblaciones de mosquitos según la localidad fueron visualizadas mediante análisis no apareado de la media aritmética. Las áreas idóneas de distribución geográfica real y potencial de estas poblaciones de Ae. aegypti fueron analizadas mediante DIVA-GIS 7.3.0 y MAXENT. Resultados: Se identificaron 40 loci mediante perfiles RAPD-PCR, con diferenciación génica moderada (Gst = 0,12). El corredor transfronterizo presentó condiciones bioclimáticas para la presencia de poblaciones variantes de Ae. aegypti, siendo determinantes en la distribución la precipitación del trimestre más cálido y la temperatura media del trimestre más seco. Conclusiones: Se evidencia que existe diversidad genética moderada en las poblaciones de Ae. aegypti procedentes de zonas con registros de casos de dengue ubicadas en el corredor vial transfronterizo que une los departamentos Central y Alto Paraná de Paraguay. El estudio de variabilidad genética de Ae. aegypti es de gran utilidad para la vigilancia entomoepidemiológica y evaluación de posibles eventos de resistencia al control químico.
ABSTRACT Objective: To determine the genetic diversity of Aedes aegypti in the Central-Alto Paraná cross-border road corridor of Paraguay, an area that has reports of dengue cases. Materials and methods: Twenty adult females were selected from hatching Ae. aegypti eggs from households geolocated in the departments of Alto Paraná, Caaguazú, Cordillera and Central, between 2018 and 2019. DNA was extracted from the tissue of females for amplifying their polymorphic patterns by random amplification of polymorphic DNA by PCR (RAPD-PCR), using primers H3 and B03 in order to identify genetic parameters of population diversity. The relationships between mosquito populations according to locality were observed by unpaired arithmetic mean analysis. We used DIVA-GIS 7.3.0 and MAXENT to analyze the suitable areas of actual and potential geographic distribution of these Ae. aegypti populations. Results: Forty loci were identified by RAPD-PCR profiling, with moderate gene differentiation (Gst = 0.12). The cross-border corridor presented bioclimatic conditions for the presence of variant populations of Ae. aegypti, with precipitation in the warmest quarter and mean temperature in the driest quarter being determinant in the distribution. Conclusions: There is evidence of moderate genetic diversity in Ae. aegypti populations from areas that have reported dengue cases in the cross-border road corridor linking the Central and Alto Paraná departments of Paraguay. The study of genetic variability of Ae. aegypti is very useful for entomo-epidemiological surveillance and evaluation of possible resistance to chemical control.

BACKGROUND: The Venezuelan Report Card on Physical Activity for Children and Youth is the first assessment of information related to physical activity in Venezuela. It provides a compilation of existing information throughout the country and assesses how well it is doing at promoting opportunities for children and youth. The aim of this article is to summarize the information available. METHODS: Thirteen physical activity indicators were graded by a committee of experts using letters A to F (A, the highest, to F, the lowest) based on national surveys, peer review studies, and policy documents. RESULTS: Some indicators report incomplete information or a lack of data. Overweight and Obesity were classified as A; Body Composition and Nongovernmental Organization Policies as B; Municipal Level Policies as C; and Overall Physical Activity Levels and National Level Policies as D. CONCLUSIONS: 63% of children and youth have low physical activity levels. Venezuela needs to undergo a process of articulation between the several existing initiatives, and for said purposes, political will and a methodological effort is required. Investments, infrastructure, and opportunities will be more equal for all children and youth if more cooperation between institutions is developed and communication strategies are applied.

Perampanel, a non-competitive antagonist of the α-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid receptors, is the most recent antiepileptic drug available in Spain, marketed in January 2014. It was initially approved by the European Medicines Agency as adjunctive treatment for partial-onset seizures in patients 12 years and older, but recently also for primary generalized tonic-clonic seizures. Although clinical trials provide essential information about the drug, they do not reflect daily clinical practice. This retrospective study shows the initial experience with perampanel in 11 Spanish hospitals during its first year post-commercialisation. All patients who started perampanel treatment were included, but efficacy and tolerability were only assessed in those patients with a minimum follow-up period of six months. In total, 256 patients were treated with perampanel before September 2014, and 253 had an observational period of one year. After six months, 216/256 patients (84%) continued on perampanel and 180/253 (71.1%) completed one year of treatment. The mean number of previous antiepileptic drugs used was 6.83 and the median number of concomitant antiepileptic drugs was 2. The mean perampanel dose was 7.06 mg and 8.26 mg at six and 12 months, respectively. The responder rate was 39.5% and 35.9% at both follow-up points, respectively. Adverse events were experienced by 91/253 (35.5%) and resulted in withdrawal in 37 (14.6%). The most common adverse events were somnolence, dizziness, and irritability. We found no significant differences between concomitant use of enzyme-inducing and non-inducing antiepileptic drugs, regarding efficacy, adverse effects, or withdrawals. Irritability was not influenced by concomitant use of levetiracetam, relative to other drugs, but was more frequently observed in patients with a history of psychiatric problems or learning disabilities.
