Reducing intersectional stigma among transgender women in Brazil to promote uptake of HIV testing and PrEP: study protocol for a randomised controlled trial of Manas por Manas.

INTRODUCTION: Globally, transgender ('trans') women experience extreme social and economic marginalisation due to intersectional stigma, defined as the confluence of stigma that results from the intersection of social identities and positions among those who are oppressed multiple times. Among trans women, gender-based stigma intersects with social positions such as engagement in sex work and substance use, as well as race-based stigma to generate a social context of vulnerability and increased risk of HIV acquisition. In Brazil, trans women are the 'most at-risk' group for HIV, with 55 times higher estimated odds of HIV infection than the general population; further, uptake of HIV testing and pre-exposure prophylaxis (PrEP) among trans women is significantly lower than other at-risk groups. Through extensive formative work, we developed Manas por Manas, a multilevel intervention using HIV prevention strategies with demonstrated feasibility and acceptability by trans women in Brazil, to address intersectional stigma and increase engagement in the HIV prevention continuum. METHODS AND ANALYSIS: We are conducting a two-arm randomised wait-list controlled trial of the intervention's efficacy in São Paulo, Brazil, to improve uptake of HIV testing and PrEP among transgender women (N=400). The primary outcomes are changes in HIV testing (self-testing and clinic based), changes in PrEP uptake and changes in PrEP persistence at baseline and follow-up assessment for 12 months at 3-month intervals. ETHICS AND DISSEMINATION: This study was approved by University of California, San Francisco Institutional Review Board (15-17910) and Comissão Nacional de Ética em Pesquisa (Research Ethics National Commission, CAAE: 25215219.8.0000.5479) in Brazil. Participants provided informed consent before enrolment. We are committed to collaboration with National Institutes of Health officials, other researchers, and health and social services communities for rapid dissemination of data and sharing of materials. The results will be published in peer-reviewed academic journals and scientific presentations. TRIAL REGISTRATION NUMBER: NCT03081559.

Right Bundle Branch Block Predicts Appropriate Implantable Cardioverter Defibrillator Therapies in Patients with Non-Ischemic Dilated Cardiomyopathy and a Prophylactic Implantable Cardioverter Defibrillator.

Background: The benefit of prophylactic implantable cardioverter defibrillators (ICDs) in patients with severe systolic dysfunction of non-ischemic origin is still unclear, and the identification of patients at risk for sudden cardiac death remains a major challenge. Aims/Methods: We retrospectively reviewed all consecutive patients with non-ischemic dilated cardiomyopathy (NICM) who underwent prophylactic ICD implantation between 2008 and 2020 in two tertiary centers. Our main goal was to identify the predictors of appropriate ICD therapies (anti-tachycardia pacing [ATP] and/or shocks) in this cohort of patients. Results: A total of 224 patients were included. After a median follow-up of 51 months, 61 patients (27.2%) required appropriate ICD therapies. Patients with appropriate ICD therapies were more frequently men (87% vs. 69%, p = 0.006), of younger age (59 years, (53-65) vs. 64 years, (57-70); p = 0.02), showed more right bundle branch blocks (RBBBs) (15% vs. 4%, p = 0.007) and less left bundle branch blocks (LBBBs) (26% vs. 47%, p = 0.005) in the ECG, and had higher left ventricular end-diastolic (100 mL/m2, (90-117) vs. 86, (71-110); p = 0.011) and systolic volumes (72 mL/m2, (59-87) vs. 61, (47-81), p = 0.05). In a multivariate competing-risks regression analysis, RBBB (HR 2.26, CI 95% 1.02-4.98, p = 0.043) was identified as an independent predictor of appropriate ICD therapies. Conclusion: RBBBs may help to identify patients with NICM at high risk of ventricular arrhythmias and requiring ICD intervention.

Wunderlich Syndrome in a Patient With Type 1 Diabetes Mellitus: Surgical Challenges and Management Strategies.

Wunderlich syndrome, a rare manifestation of spontaneous renal hemorrhage often attributed to renal angiomyolipomas, presents a complex clinical scenario demanding nuanced management. This article delves into the multifaceted dimensions of this syndrome, dissecting its clinical, diagnostic, and therapeutic intricacies. Illustrating this complexity is the case of a 26-year-old female with Wunderlich syndrome and comorbid type 1 diabetes mellitus, revealing challenges at the intersection of these conditions. While initial intervention via laparoscopic drainage and antibiotic therapy yielded symptomatic relief, the subsequent recurrence of a renal abscess prompted a re-evaluation of the treatment strategy, culminating in a second surgical intervention. The intricate interplay between Wunderlich syndrome and diabetes introduces unique challenges, with fluctuations in hemoglobin and recurrent leukocytosis mirroring the underlying complexities of this clinical dyad. This case underscores the indispensability of a multidisciplinary approach, seamlessly integrating medical and surgical modalities, coupled with vigilant postoperative monitoring. Swift identification of complications and adaptability of the treatment plan emerged as pivotal in addressing recurrent manifestations and averting long-term sequelae. The necessity for continuous surveillance and personalized management strategies becomes evident, emphasizing Wunderlich syndrome as a clinical entity requiring bespoke attention. In conclusion, this case serves as an example, highlighting the intricate nature of Wunderlich syndrome, accentuated by the presence of type 1 diabetes mellitus. The initial therapeutic success, followed by a recurrence, underscores the need for ongoing research, paving the way for refined diagnostic and treatment paradigms. The synthesis of clinical complexities in this scenario elucidates the imperative for a comprehensive understanding, guiding future endeavors aimed at optimizing the prognosis of patients affected by this uncommon syndrome.

Unbridled Threat of Gas Gangrene in a Patient With Uncontrolled Diabetes Mellitus: A Compelling Case Report of Clostridium perfringens Infection.

Clostridium perfringens, a Gram-positive anaerobic bacterium, is well-known for its association with gas gangrene, a severe and rapidly progressing infection characterized by tissue gas production and necrosis. In this case report, we present the instance of a 64-year-old male with poorly controlled diabetes mellitus who developed a C. perfringens-related infection following a traumatic foot wound. The report emphasizes the critical significance of early diagnosis and aggressive treatment in C. perfringens infections, particularly in patients with underlying risk factors. Detailed accounts of clinical findings, laboratory results, computed tomography, and surgical interventions are provided. A multidisciplinary approach proved essential for successful management. The inherent scholarly value of this case is substantiated by its meticulous documentation of the clinical trajectory, diagnostic modalities, and treatment modalities employed. The intricate collaboration across diverse medical disciplines, the uncommon manifestation of the infection following a traumatic foot wound, and the favorable outcome achieved through prompt and multidisciplinary intervention collectively contribute to the exceptional nature and didactic significance of this case. The dissemination of such clinical experiences assumes paramount importance in advancing medical scholarship, cultivating awareness, and engendering a profound comprehension of the complexities associated with C. perfringens infections, thereby enriching the wider scientific and medical community.

UBUIngenio: extracurricular enrichment programme for the improvement of high ability students' creative thinking

Background: High-ability students require effective educational strategies. This study introduces and evaluates a curriculum enrichment programme aimed at enhancing cre ativity. The programme is based on a competency framework and was implemented using variations of Project-Based Learning (PBL) strategies. Method: A quasi-experimental design compared two interventions using pre-test and post-test groups. The first intervention (N = 38) involved a 12-week PBL unit focused on designing a video game using block-based program ming through Scratch. The second intervention (N = 51), also lasting 12 weeks, comprised three separate projects involving vectorial design and programming of an Arduino-based ro bot. Both interventions used strategies for creative-thinking development. The sample includ ed high-ability students from 8 to 12 years of age. Results: Both interventions significantly increased creativity, with no statistical differences between them. This suggests that both types of PBL interventions effectively improved participants' creativity. Conclusions: This study suggests that PBL-based curricular enrichment programmes are effective in fostering creativity among high-ability students.

Antecedentes: Los estudiantes con alta capacidad requieren estrategias educativas efectivas. Este estudio presenta y evalúa un programa de enriquecimiento curricular diseñado para mejorar la creatividad.

Resultados: Ambas intervenciones aumentaron significativamente la creatividad, sin diferencias estadísticas entre ellas. Esto sugiere que ambos tipos de intervenciones de ABP mejoraron efectivamente la creatividad de los participantes. Conclusiones: Este estudio sugiere que los programas de enriquecimiento curricular basados en ABP son efectivos para fomentar la creatividad entre los estudiantes con altas capacidades.

Aphasia improvement without logotherapy during motor neurorehabilitation of post-stroke hemiparesis using virtual reality or modified constraint-induced movement therapy: A retrospective cohort.

BACKGROUND: Some research suggests that post-stroke aphasia can recover "on its own", however, there is evidence of a common neural substrate for motor and language systems. We hypothesize, that motor neurorehabilitation of hemiparesis could be related to simultaneous improvement in aphasia. OBJECTIVE: To measure changes in post-stroke aphasia and its relation with hemiparesis treated with different therapies. METHODS: Database information (n = 32) on post-stroke hemiparesis (Fugl-Meyer Scale evaluated) managed with virtual reality (VR) versus modified constraint-induced movement therapy (mCIMT) or regular therapy (rPT/OT) was analyzed. None received logotherapy (LT) by appointment at four months. INCLUSION CRITERIA: < 3 months after the stroke, aphasia severe (Boston Aphasia Intensity Scale), and all three evaluations. RESULTS: Twenty-one patient records met inclusion criteria (71,4% women and mean age 66,67±3,13 years) who received VR, mCIMT, or rPT/OT (n = 6, 8, and 7, respectively). There was continuous intra-groups improvement in aphasia (p < 0.05), but inter-groups the greater aphasia recovery (p = 0.05) and hemiparesis (p = 0.02) were in VR, with a high correlation in evolution between them (r = 0.73; p = 0.047). CONCLUSION: High clinical correlation between aphasia, without LT, and hemiparesis evolution during motor neurorehabilitation would support common neural connections stimulation. We will conduct a clinical trial, with a larger sample size to contrast our hypothesis.

Effective Management of Giant Ventral Hernias: A Comprehensive Approach Combining Preoperative Botulinum Toxin Application, Modified Ramírez's Component Separation, and Rives-Stoppa Hernioplasty.

Introduction  Giant ventral hernias are a surgical challenge due to their size and the need for a specialized approach during repair. Over the decades, abdominal wall surgery has evolved into a sophisticated field with a wide range of techniques aimed at improving patient outcomes. However, there is no universally accepted method suitable for repairing all giant ventral hernias. Surgeons must rely on a combination of techniques, choosing the approach that best matches their expertise, available resources, and the individual patient's specific needs. This article explores the effective use of a combination of techniques, including preoperative botulinum toxin application, modified Ramírez's component separation, and Rives-Stoppa hernioplasty, yielding excellent results and minimizing recurrences. Objective  This study aims to provide a comprehensive literature review of giant ventral hernias. Additionally, we aim to share our experience in managing and repairing giant ventral hernias using a multi-modal approach, combining various surgical techniques with a focus on patient safety, reduced recurrence rates, and improved quality of life. Methods Between October 1, 2019, and October 1, 2021, six patients with giant ventral hernias were enrolled at our department of surgery. They received preoperative botulinum toxin A (BT) application, underwent corrective surgery involving modified component separation following the Ramírez method, and received Rives-Stoppa hernioplasty. Follow-up was conducted for at least six months. Results Six patients were included in the study: three women and three men. They had an average age of 53.6 years and an average body mass index of 31.8 kg/m2. The most common location of the hernia defect was supra and infraumbilical, among 66% of cases. The primary adverse effect associated with BT application was abdominal distension, reported in 33% of patients. No postoperative complications, such as abscesses or seromas, were observed. After the surgical procedure, the average hospital stay was 2.6 days, and no recurrences were noted within six months post-surgery. Conclusion  The proposed method, which involves a combination of techniques, has demonstrated promising results based on our experience. However, to solidify these findings and better understand the full scope of this approach, further comprehensive statistical studies involving larger populations are essential. These studies will not only validate our results but also provide valuable insights for optimizing the management of giant ventral hernias.

Conduction system pacing and atrioventricular node ablation in heart failure: The PACE-FIB study design.

AIMS: Atrial fibrillation (AF) worsens the prognosis of patients with heart failure (HF). Successful treatments are still very scarce for those with permanent AF and preserved (HFpEF) or mildly reduced (HFmrEF) ejection fraction. In this study, the long-term benefits and safety profile of heart rate regularization through left-bundle branch pacing (LBBP) and atrioventricular node ablation (AVNA) will be explored in comparison with pharmacological rate-control strategy. METHODS AND RESULTS: The PACE-FIB trial is a multicentre, prospective, open-label, randomized (1:1) clinical study that will take place between March 2022 and February 2027. A total of 334 patients with HFpEF/HFmrEF and permanent AF will receive either LBBP followed by AVNA (intervention arm) or optimal pharmacological treatment for heart rate control according to European guideline recommendations (control arm). All patients will be followed up for a minimum of 36 months. The primary outcome measure will be the composite of all-cause mortality, HF hospitalization, and worsening HF at 36 months. Other secondary efficacy and safety outcome measures such as echocardiographic parameters, functional status, and treatment-related adverse events, among others, will be analysed too. CONCLUSION: LBBP is a promising stimulation mode that may foster the clinical benefit of heart rate regularization through AV node ablation compared with pharmacological rate control. This is the first randomized trial specifically addressing the long-term efficacy and safety of this pace-and-ablate strategy in patients with HFpEF/HFmrEF and permanent AF.

The Extended-Sphenoid Ridge Approach: A New Technique for the Surgical Treatment of Skull Base Tumors in Pediatric Patients.

The sphenoid ridge approach (SRA) was initially described as a surgical technique for treating vascular pathologies near the Sylvian fissure. However, limited studies have systematically explored the use of skull base techniques in pediatric patients. This study investigated an extended variation in the sphenoid ridge approach (E-SRA), which systematically removed the pterion, orbital walls (roof and lateral wall), greater sphenoid wing, and anterior clinoid process to access the base of the skull. OBJECTIVE: This report aimed to evaluate the advantages of the extradural removal of the orbital roof, pterion, sphenoid wing, and anterior clinoid process as a complement to the sphenoid ridge approach in pediatric patients. PATIENTS AND METHODS: We enrolled 36 patients with suspected neoplastic diseases in different regions. The E-SRA was performed to treat the patients. Patients were included based on the a priori objective of a biopsy or a total gross resection. The surgical time required to complete the approach, associated bleeding, and any complications were documented. RESULTS: Our results demonstrated that the proposed a priori surgical goal, biopsy, or resection were successfully achieved in all cases. In addition, using the E-SRA technique was associated with a shorter operative time, minimal bleeding, and a lower incidence of complications. The most frequently encountered complications were related to dural closure. CONCLUSIONS: The extended sphenoid ridge approach represents a safe and effective option for managing intracranial tumors in pediatrics.

Case Series of Ventricular Tachycardia Ablation With Pulsed-Field Ablation: Pushing Technology Further (Into the Ventricle).

Three cases of ventricular tachycardia ablation with pulsed-field ablation technology performed at 2 separate centers are reported, highlighting the advantages and disadvantages of this tool inside the ventricle: its dependence on proximity rather than contact makes it useful in sites with poor stability, while the speed of application and large scope of action provided by commercially available catheters could help with ablating large diseased areas of endocardium in a fast and hemodynamically well-tolerated fashion. However, lesion depth could be insufficient for guaranteeing efficacy in preventing ventricular tachycardias originating at an epicardial site, even in the right ventricle.

Efficacy of a treatment program based on positive psychology for drug use in juvenile offenders. / Eficacia de un programa de tratamiento en el consumo de drogas en menores infractores desde la psicología positiva.

One of the factors that increase the likelihood of adolescents starting to exhibit and consolidate anti-social behavior is drug use, with a consistent pattern of consumption of different substance found in young offenders (Aebi, Bessler & Steinhausen, 2021). A cognitive-behavioral group treatment program inspired by the positive psychology approach was developed and applied to drug use in minors deprived of liberty (experimental group); the results were compared to those of a group of adolescents with the same type of drug use in the same center (active control group) at two points in time: during and after incarceration. The fall in the rate of problems associated with drug use after incarceration in the experimental group was statistically significant compared to the control group, and the effect size of the experimental condition was large (ῆ^2 = 0.55), much higher than the control group (ῆ^2 = 0.16). The treatment program has proven to be an effective tool for reducing problems associated with drug use and is especially effective in reducing alcohol and cannabis consumption.

Uno de los factores que aumentan en mayor medida la probabilidad de que los adolescentes inicien y consoliden comportamientos antisociales es el consumo de drogas, encontrándose un patrón consistente de consumo de diferentes sustancias en los menores infractores (Aebi, Bessler y Steinhausen, 2021). Para la redacción del presente trabajo se desarrolló y aplicó un programa de tratamiento, de corte cognitivo ­ conductual e inspirado en el enfoque de la psicología positiva, para el consumo de drogas en menores de edad privados de libertad (grupo experimental). Los resultados se compararon con los de un grupo de adolescentes con la misma tipología de consumo internos en el mismo Centro (grupo control activo) en dos momentos, durante y tras el internamiento. El grupo experimental redujo de manera estadísticamente significativa la tasa de problemas asociados al consumo de drogas en comparación con el grupo control tras el internamiento, siendo el tamaño del efecto de la condición experimental elevado (ῆ

Survey of Candidatus Liberibacter Solanacearum and Its Associated Vectors in Potato Crop in Spain.

'Candidatus Liberibacter solanacearum' (CaLsol), the etiological agent of potato zebra chip (ZC), is transmitted to potato plants by the psyllid Bactericera cockerelli (Sulc, 1909) in North and Central America and New Zealand. The risk of the dispersion of ZC in Spain depends on the presence of an efficient vector. This work studies the presence and abundance of ZC symptoms and CaLsol in potato plants, as well as the presence and abundance of psyllid species associated with potato crops in the main producing areas in Spain. Eighty-eight plots were surveyed punctually to detect ZC symptoms and psyllid species in the main potato-producing areas. Furthermore, fourteen potato plots were surveyed by different sampling methods during the cropping season to detect psyllid species from 2016 to 2018. Very few symptomatic and CaLsol-positive plants were detected in Mainland Spain, and any positive plant was detected in the Canary Islands. Most of the adult psyllids captured were identified as Bactericera nigricornis (Foerster, 1848), and some of them as Bactericera trigonica, but no B. cockerelli was detected. B. nigricornis was found widely distributed in the northern half of the Iberian Peninsula; however, this psyllid does not seem sufficient to pose a threat to potato production, due to the scarce number of specimens and because the frequency of B. nigricornis specimens that were CaLsol+ was very low.

Value of advanced interatrial block in the diagnosis of the ischemic stroke's aetiology: A cohort study

Introduction and objectives: Advanced interatrial block has been linked with atrial fibrillation (AF) (Bayes syndrome). On the other hand, the aetiology of the stroke remains unknown in approximately 20–25% of patients admitted due to ischaemic stroke. The aim of this study was to evaluate whether advanced interatrial block and CHADS2-VASC scale is linked to AF in patients admitted due to ischaemic stroke without previous AF history.MethodsA prospective analysis of consecutive in-hospital patients admitted with ischemic stroke between January/2018 and April/2019 in a stroke hospital was performed. Patients had to be in sinus rhythm at admission and without previous history of AF/atrial flutter. During follow up patients receive the usual care.ResultsA total of 236 patients were included. The median follow-up was 540 days (407–695). 19 patients (8.1%) had advanced interatrial block at admission. Advanced interatrial block was associated with the diagnosis of AF during follow up (5 (26.3%) Vs 21 (9.7%) p=0.027). A CHADS2-VASC score>4 at admission was also associated with AF diagnosis during follow up (23(14.6%) vs 3(3.9%) p=0.009).ConclusionThis study confirms the association of advanced interatrial block and CHADS2-VASC>4 at admission with the diagnosis of AF during follow up in patients with ischemic stroke. This association could have important implications in patients with ischemic stroke who present advanced interatrial block and without previous history of AF. (AU)

Introducción y objetivos: El bloqueo interauricular (BIA) completo se relaciona con el desarrollo de arritmias supraventriculares, especialmente de fibrilación auricular (FA) (síndrome de Bayés). En este trabajo evaluamos la utilidad de este fenómeno para discernir la etiología cardioembólica en los pacientes ingresados por ictus isquémico. También se estudió la relación entre la puntuación en la escala CHADS 2-VA 2 Sc y el desarrollo de FA durante el seguimiento.MétodosAnálisis prospectivo de pacientes consecutivos ingresados por ictus isquémico entre enero del 2018 y abril del 2019 en un hospital terciario centro de referencia de ictus. Los pacientes incluidos debían de estar en ritmo sinusal en el momento del ingreso y no tener historia previa de FA/flutter auricular. Se realizó el seguimiento mediante las consultas y estudios de rutina, sin intervenir en su manejo habitual.ResultadosSe incluyó a 236 pacientes. La mediana de seguimiento fue de 540 días (407-695); 19 pacientes (8,1%) presentaron BIA en el electrocardiograma al ingreso. El BIA completo al ingreso se relacionó con el desarrollo posterior de FA (5 [26,3%) vs. 21 [9,7%]; p=0,027). También se observó que un CHADS 2-VA 2 Sc>4 al ingreso se relacionaba con presentar FA durante el seguimiento (23 [14,6%] vs. 3 [3,9%]; p=0,009).ConclusiónCon este estudio se demuestra por primera vez en pacientes con ictus isquémico que tanto el BIA completo como un CHADS 2-VA 2 Sc>4 se asocian con el desarrollo de FA en el seguimiento. Esta asociación puede tener importantes implicaciones prácticas en el manejo de pacientes ingresados por ictus que presenten BIA completo. (AU)
