RESUMO
BACKGROUND: Informed consent is essential for any surgery. The use of digital education platforms (DEPs) can enhance patient understanding of the consent discussion and is a method to standardize the consent process in elective, ambulatory settings. The use of DEP as an adjunct to standard verbal consent (SVC) has not been studied in an acute care setting. METHODS: We conducted a prospective randomized control trial with patients presenting to the emergency department of a tertiary care hospital with acute biliary pathology requiring a laparoscopic cholecystectomy (LC) between August 2021 and April 2023. Participants were randomized 1:1 to receive either a DEP module with SVC or SVC alone. Baseline procedure-specific knowledge and self-reported understanding of risks and benefits of LC were collected using a questionnaire. Primary outcome was immediate post-intervention knowledge assessed using a 21-question multiple choice questionnaire. Secondary outcomes were delayed procedure-specific knowledge and participants' satisfaction with the consent discussion. RESULTS: We recruited 79 participants and randomized them 1:1 into the intervention group (DEP + SVC, n = 40) and the control group (SVC, n = 39). Baseline demographics and baseline procedure-specific knowledge were similar between groups. The immediate post-intervention knowledge was significantly higher for participants in the intervention versus the control group with a Cohen's d effect size of 0.68 (85.2(10.6)% vs. 78.2(9.9)%; p = 0.004). Similarly, self-reported understanding of risks and benefits of LC was significantly greater for participants in the intervention versus the control group with a Cohen's effect size of 0.76 (68.5(16.4)% vs. 55.1(18.8)%; p = 0.001). For participants who completed the delayed post-intervention assessment (n = 29), there continued to be significantly higher retention of acquired knowledge in the intervention group with a Cohen's effect size of 0.61 (86.5(8.5)% vs. 79.8 (13.1)%; p = 0.024). There was no difference in participants' self-reported satisfaction with the consent discussion between groups (69.5(6.7)% vs. 67.2(7.7)%; p = 0.149). CONCLUSION: The addition of digital education platform to standard verbal consent significantly improves patient's early and delayed understanding of risks and benefits of LC in an acute care setting.

BACKGROUND: General surgeons play an important role in the provision of trauma care in Canada and the current extent of their trauma experience during training is unknown. We sought to quantify the operative and nonoperative educational experiences among Canadian general surgery trainees. METHODS: We conducted a multicentre retrospective study of major operative exposures experienced by general surgery residents, as identified using institutional trauma registries and subsequent chart-level review, for 2008-2018. We also conducted a site survey on trauma education and structure. RESULTS: We collected data on operative exposure for general surgery residents from 7 programs and survey data from 10 programs. Operations predominantly occurred after hours (73% after 1700 or on weekends) and general surgery residents were absent from a substantial proportion (25%) of relevant trauma operations. The structure of trauma education was heterogeneous among programs, with considerable site-specific variability in the involvement of surgical specialties in trauma care. During their training, graduating general surgery residents each experienced around 4 index trauma laparotomies, 1 splenectomy, 1 thoracotomy, and 0 neck explorations for trauma. CONCLUSION: General surgery residents who train in Canada receive variable and limited exposure to operative and nonoperative trauma care. These data can be used as a baseline to inform the application of competency-based medical education in trauma care for general surgery training in Canada.

A majority of individuals with limited English proficiency (LEP) in the U.S. are foreign-born, creating a complex intersection of language, socio-economic, and policy barriers to healthcare access and achieving good outcomes. Mapping the research literature is key to addressing how LEP intersects with healthcare. This scoping review followed PRISMA-ScR guidelines and included PubMed/MEDLINE, CINAHL, Sociological Abstracts, EconLit, and Academic Search Premier. Study selection included quantitative studies since 2000 with outcomes specified for adults with LEP residing in the U.S. related to healthcare service access or defined health outcomes, including healthcare costs. A total of 137 articles met the inclusion criteria. Major outcomes included ambulatory care, hospitalization, screening, specific conditions, and general health. Overall, the literature identified differential access to and utilization of healthcare across multiple modalities with poorer outcomes among LEP populations compared with English-proficient populations. Current research includes inconsistent definitions for LEP populations, primarily cross-sectional studies, small sample sizes, and homogeneous language and regional samples. Current regulations and practices are insufficient to address the barriers that LEP individuals face to healthcare access and outcomes. Changes to EMRs and other data collection to consistently include LEP status and more methodologically rigorous studies are needed to address healthcare disparities for LEP individuals.
RESUMO
Chronic endometritis (CE) in humans is asymptomatic inflammation of the endometrium, associated with poor reproductive outcomes. Similarly asymptomatic endometrial inflammation in cows, termed subclinical endometritis (SCE), is associated with adverse reproductive outcomes. While the pathophysiology and treatment options for CE in humans remains poorly defined, the financial implications of SCE in dairy cows mean it has been intensively researched. We performed a systematic review with an emergent theme thematic analysis of studies of SCE in cows, to determine potential areas of interest in human CE research. A literature search for studies of subclinical endometritis in cows published between 1990 and November 2021 was performed across Embase, Medline, Scopus and CINAHL. Studies of symptomatic or clinical endometritis were excluded. Thematic analysis across two broad themes were explored: diagnostic methods and pathophysiology of SCE. In total, 44 bovine studies were included. 12 studies reported on diagnostic methodology. The primary emergent theme was the use of cytology for the diagnosis of SCE. This method has a lower sensitivity than histopathology but is less invasive and more specific than alternative techniques of ultrasound, vaginoscopy, or metabolic markers. The subthemes related to pathophysiology were identified as type of endometritis, metabolic stress, artificial insemination, infective causes, and altered cellular pathways. Despite the lack of symptoms, cellular pathways of inflammation including NFkB, MAPK, and inflammasomes were found to be activated. The key themes related to the diagnosis and pathophysiology of SCE in cows identified in this systematic review highlight potential areas for future research into human CE.
RESUMO
Post vaccine immunity following COVID-19 mRNA vaccination may be driven by extrinsic, or controllable and intrinsic, or inherent health factors. Thus, we investigated the effects of extrinsic and intrinsic on the peak antibody response following COVID-19 primary vaccination and on the trajectory of peak antibody magnitude and durability over time. Participants in a longitudinal cohort attended visits every 3 months for up to 2 years following enrollment. At baseline, participants provided information on their demographics, recreational behaviors, and comorbid health conditions which guided our model selection process. Blood samples were collected for serum processing and spike antibody testing at each visit. Cross-sectional and longitudinal models (linear-mixed effects models) were generated to assess the relationship between selected intrinsic and extrinsic health factors on peak antibody following vaccination and to determine the influence of these predictors on antibody over time. Following cross-sectional analysis, we observed higher peak antibody titers after primary vaccination in females, those who reported recreational drug use, younger age, and prior COVID-19 history. Following booster vaccination, females and Hispanics had higher peak titers after the 3rd and 4th doses, respectively. Longitudinal models demonstrated that Moderna mRNA-1273 recipients, females, and those previously vaccinated had increased peak titers over time. Moreover, drug users and half-dose Moderna mRNA-1273 recipients had higher peak antibody titers over time following the first booster, while no predictive factors significantly affected post-second booster antibody responses. Overall, both intrinsic and extrinsic health factors play a significant role in shaping humoral immunogenicity after initial vaccination and the first booster. The absence of predictive factors for second booster immunogenicity suggests a more robust and consistent immune response after the second booster vaccine administration.

Introduction: This study sought to determine the effect of Occupational Safety and Health Administration (OSHA) compliant noise on auditory health and assess whether pre-noise near infrared (NIR) light therapy can mitigate the effects of noise exposure. Methods: Over four visits, participants (n = 30, NCT#: 03834714) with normal hearing completed baseline hearing health assessments followed by exposure to open ear, continuous pink noise at 94 dBA for 15 min. Immediately thereafter, post-noise hearing tests at 3000, 4000, and 6000 Hz and distortion product otoacoustic emissions (DPOAEs) were conducted along with the Modified Rhyme Test (MRT), Masking Level Difference Test (MLD), and Fixed Level Frequency Tests (FLFT) [collectively referred to as the Central and Peripheral Auditory Test Battery (CPATB)] to acquire baseline noise sensitivity profiles. Participants were then randomized to either Active or Sham NIR light therapy for 30 min binaurally to conclude Visit 1. Visit 2 (≥24 and ≤ 48 h from Visit 1) began with an additional 30-min session of Active NIR light therapy or Sham followed by repeat CPATB testing and noise exposure. Post-noise testing was again conducted immediately after noise exposure to assess the effect of NIR light therapy. The remaining visits were conducted following ≥2 weeks of noise rest in a cross-over design (i.e., those who had received Active NIR light therapy in Visits 1 and 2 received Sham therapy in Visits 3 and 4). Results: Recovery hearing tests and DPOAEs were completed at the end of each visit. Participants experienced temporary threshold shifts (TTS) immediately following noise exposure, with a mean shift of 6.79 dB HL (±6.25), 10.61 dB HL (±6.89), and 7.30 dB HL (±7.25) at 3000, 4000, and 6000 Hz, respectively, though all thresholds returned to baseline at 3000, 4000, and 6000 Hz within 75 min of noise exposure. Paradoxically, Active NIR light therapy threshold shifts were statistically higher than Sham therapy at 3000 Hz (p = 0.04), but no other differences were observed at the other frequencies tested. An age sub-analysis demonstrated that TTS among younger adults were generally larger in the Sham therapy group versus Active therapy, though this was not statistically different. There were no differences in CPATB test results across Active or Sham groups. Finally, we observed no changes in auditory function or central processing following noise exposure, suggestive of healthy and resilient inner ears. Conclusion: In this study, locally administered NIR prior to noise exposure did not induce a significant protective effect in mitigating noise-induced TTS. Further exploration is needed to implement effective dosage and administration for this promising otoprotective therapy.
RESUMO
Involving diverse populations in early-phase (phase I and II) cancer clinical trials is critical to informed therapeutic development. However, given the growing costs and complexities of early-phase trials, trial activation and enrollment barriers may be greatest for these studies at healthcare facilities that provide care to the most diverse patient groups, including those in historically underserved communities (e.g., safety-net healthcare systems). To promote diverse and equitable access to early-phase cancer clinical trials, we are implementing a novel program for the transfer of care to enhance access to early-phase cancer clinical trials. We will then perform a mixed-methods study to determine perceptions and impact of the program. Specifically, we will screen, recruit, and enroll diverse patients from an urban, integrated safety-net healthcare system to open and active early-phase clinical trials being conducted in a university-based cancer center. To evaluate this novel program, we will: (1) determine program impact and efficiency; and (2) determine stakeholder experience with and perceptions of the program. To achieve these goals, we will conduct preliminary cost analyses of the program. We will also conduct surveys and interviews with patients and caregivers to elucidate program impact, challenges, and areas for improvement. We hypothesize that broadening access to early-phase cancer trials conducted at experienced centers may improve equity and diversity. In turn, such efforts may enhance the efficiency and generalizability of cancer clinical research.
RESUMO
Vesicular monoamine transporter 2 (VMAT2) is an essential transporter that regulates brain monoamine transmission and is important for mood, cognition, motor activity, and stress regulation. However, VMAT2 remains underexplored as a pharmacological target. In this study, we report that tricyclic and tetracyclic antidepressants acutely inhibit, but persistently upregulate VMAT2 activity by promoting VMAT2 protein maturation. Importantly, the VMAT2 upregulation effect was greater in BE(2)-M17 cells that endogenously express VMAT2 as compared to a heterologous expression system (HEK293). The net sustained effect of tricyclics and tetracyclics is an upregulation of VMAT2 activity, despite their acute inhibitory effect. Furthermore, imipramine and mianserin, two representative compounds, also demonstrated rescue of nine VMAT2 variants that cause Brain Monoamine Vesicular Transport Disease (BMVTD). VMAT2 upregulation could be beneficial for disorders associated with reduced monoamine transmission, including mood disorders and BMVTD, a rare but often fatal condition caused by a lack of functional VMAT2. Our findings provide the first evidence that small molecules can upregulate VMAT2 and have potential therapeutic benefit for various neuropsychiatric conditions.
RESUMO
Objectives: Judgments of the subjective visual vertical (SVV) and subjective visual horizontal (SVH) while seated upright are commonly included in standard clinical test batteries for vestibular function. We examined SVV and SVH data from retrospective control to assess their statistical distributions and normative values for magnitudes of the preset effect, sex differences, and fixed-head versus head-free device platforms for assessment. Methods: Retrospective clinical SVV and SVH data from 2 test platforms, Neuro-otologic Test Center (NOTC) and the Neurolign Dx 100 (I-Portal Portable Assessment System Nystagmograph) were analyzed statistically (SPSS and MATLAB software) for 408 healthy male and female civilians and military service members, aged 18-50 years. Results: No prominent age-related effects were observed. The preset angle effects for both SVV and SVH, and their deviations from orthogonality, agree in magnitude with previous reports. Differences attributable to interactions with device type and sex are of small magnitude. Analyses confirmed that common clinical measure for SVV and SVH, the average of equal numbers of clockwise and counterclockwise preset trials, was not significantly affected by the test device or sex of the subject. Finally, distributional analyses failed to reject the hypothesis of underlying Gaussian distributions for the clinical metrics. Conclusions: z scores based on these normative findings can be used for objective detection of outliers from normal functional limits in the clinic.
RESUMO
Objective: We performed a systematic review to determine the educational effectiveness of telementoring as a continuing professional development (CPD) intervention for surgeons in practice. Background: Surgeons can mentor their peers in remote locations using videoconferencing communication, referred to as telementoring. Methods: We searched MEDLINE and EMBASE and included studies assessing the educational effectiveness of telementoring interventions used by surgeons in practice. We excluded studies involving only trainees and those not evaluating educational effectiveness. Two reviewers independently screened, extracted data, and assessed study quality using the Medical Education Research Study Quality Instrument (MERSQI; maximum score 18). Educational outcomes were categorized using Moore's Outcomes Framework. Results: We retrieved a total of 1351 records, and 252 studies were selected for full-text review. Twenty-eight studies were included with 1 randomized controlled trial, 19 cohort studies, 5 qualitative studies, and 3 case studies, totaling 178 surgeons and 499 cases. The average MERSQI score was 10.21 ± 2.2 out of 18. Educational outcomes included surgeons' satisfaction with telementoring interventions (Moore's Level 2) in 12 studies, improvement in surgeons' procedural knowledge (Level 3b) in 3 studies, improvements in surgeons' procedural competence in an educational setting (Level 4) in 4 studies, performance in a workplace-based setting (Level 5) in 23 studies, and patient outcomes (Level 6) in 3 studies. No studies reported community health outcomes (Level 7). Conclusions: Moderate-level evidence demonstrates the use of telementoring as effective in changing surgeons' knowledge and competence in both educational and workplace-based settings. Its use is also associated with changes in patient outcomes.
RESUMO
In dairy cattle, supplementation with polyunsaturated fatty acids (PUFAs) is considered to be an important tool to decrease the negative energy balance of periparturient dairy cows and improve the reproductive and immune systems. The most common PUFAs added to ruminant diets are omega 3 (n-3 PUFA) as linolenic acid and omega 6 (n-6 PUFA) as linoleic acid. This paper aims to review the potential effects of n-3 PUFA. We consider the effects of n-3 PUFA on the bovine immune system, especially on immune cells, and on in vivo and in vitro reproductive parameters, emphasizing how n-3 PUFAs act as modulators through one or more molecular mechanisms. The incorporation of n-3 PUFA in the dairy cow diet has positive effects on animal fertility and immunity. Future research on n-3 PUFA should be more explored concerning reproduction and immune function, starting from the investigation of basic biology to their potential for application in the clinical and preventive medicine fields.(AU)
Em rebanhos leiteiros, a suplementação com ácidos graxos poliinsaturados (PUFAs) é considerada uma ferramenta importante para diminuir o balanço energético negativo de vacas leiteiras durante o periparto e contribuir para a reprodução e sistema imunológico. Os efeitos da suplementação com PUFA sobre estes sistemas têm sido pouco explorados na literatura. Os PUFAs mais comuns na dieta dos ruminantes são Ômega-3 (n-3 PUFA) como ácido linolênico e Ômega-6 (n-6 PUFA) como ácido linoleico. Esta revisão abordará os aspectos gerais do n-3 PUFA, seus efeitos mais relevantes no sistema imune, principalmente seus efeitos nas células imunes, bem como seus efeitos na parte reprodutiva, tanto in vivo como in vitro, enfatizando a ação do n-3 PUFA através de mecanismos moleculares. A incorporação de n-3 PUFAs na dieta de vacas leiteiras exerce efeitos positivos na fertilidade e imunidade. Mais estudos a fim de explorar a função do n-3 PUFA na modulação do sistema imune e parâmetros reprodutivos, desde a investigação da biologia básica até a aplicação a campo de modo clínico e preventivo, devem ser requeridos.(AU)
