RESUMEN

BACKGROUND: The HEARTS technical package was developed by the World Health Organization to address the implementation gap in cardiovascular disease prevention in low- and middle-income countries. Guatemala is a middle-income country that is currently implementing HEARTS. National authorities in Guatemala are interested in exploring how hypertension and diabetes management can be integrated in HEARTS implementation. The objective of this study is to conduct a feasibility and acceptability pilot trial of integrated hypertension and diabetes management based on HEARTS in the publicly funded primary care system in Guatemala. METHODS: A single-arm pilot trial for 6 months will be carried out in 11 Ministry of Health primary care facilities starting in September 2023. A planned sample of 100 adult patients diagnosed with diabetes (n = 45), hypertension (n = 45), or both (n = 10) will be enrolled. The intervention will consist of HEARTS-aligned components: Training health workers on healthy-lifestyle counseling and evidence-based treatment protocols, strengthening access to medications and diagnostics, training on risk-based cardiovascular disease management, team-based care and task sharing, and systems monitoring and feedback, including implementation of a facility-based electronic monitoring tool at the individual level. Co-primary outcomes of feasibility and acceptability will be assessed using an explanatory sequential mixed-methods design. Secondary outcomes include clinical effectiveness (treatment with medication, glycemic control, and blood pressure control), key implementation outcomes (adoption, fidelity, usability, and sustainability), and patient-reported outcome measures (diabetes distress, disability, and treatment burden). Using an implementation mapping approach, a Technical Advisory Committee will develop implementation strategies for subsequent scale-up planning. DISCUSSION: This trial will produce evidence on implementing HEARTS-aligned hypertension and diabetes care in the MOH primary care system in Guatemala. Results also will inform future HEARTS projects in Guatemala and other low- and middle-income countries. TRIAL REGISTRATION: ClinicalTrials.gov ID NCT06080451. The trial was prospectively registered on October 12, 2023.

RESUMEN

Background: A global outbreak of the human monkeypox virus (HMPXV), first identified in May 2022, was declared a health emergency of international concern on 23 July 2022. Before the global outbreak, monkeypox cases were mostly confined to central and west African countries, where this virus is prevalent. Close contact, mainly sexual contact, is supposed to be the main route of transmission, and it is remarkable that the incidence is higher in men who have sexual relationships with other men. Case summary: A 40-year-old Caucasian man arrived at the emergency department complaining of oppressive epigastric pain extending to the chest after a diagnosis of pharyngitis, which was suspected to be caused by the human monkeypox virus. Based on the clinical symptoms, physical examination, serum cardiac biomarkers, and electrocardiographic findings, he was diagnosed with myopericarditis. The real-time PCR for human monkeypox in skin lesions, urine, plasma, and the oropharyngeal swab was positive. The peak of troponin I was 20.6 ng/ml, and the electrocardiogram showed an upward concavity in the ST segment in diffuse leads, which was in agreement with the previous diagnosis. The presence of edema, subepicardial, and myocardial late gadolinium enhancement, and increased values on T1 mapping in the cardiac MRI were in agreement with the diagnosis of myopericarditis. Antiviral treatment with tecovirimat was started with excellent tolerability. After 6 days, the patient recovered and was discharged. Discussion: To our knowledge, this is one of the first reported cases of myopericarditis due to human monkeypox infection, which was confirmed by a cardiac MRI following modified Lake Louise criteria. The short span between the onset of the mucocutaneous symptoms and the myocardial damage suggests a pathogenic association. Furthermore, the active viral replication in plasma samples and the negative results on real-time PCR for other viruses support this clinical association.

RESUMEN

BACKGROUND: Genotypic tools based on the analysis of the V3 region are seen as an alternative to phenotypic assays for viral tropism determination before prescribing maraviroc. The concordance between different genotypic algorithms has been evaluated in HIV+ patients infected with B versus non-B subtypes. METHODS: HIV-infected patients on regular follow up at Hospital Universitario de Santiago de Compostela (Spain) were selected. The env-V3 region was sequenced from plasma samples and viral tropism was estimated using 8 different genotypic algorithms. Concordance among predictors was statistically evaluated by the calculation of the kappa index. Phylogenetic analyses were performed to determine the genetic subtype. RESULTS: A total of 92 HIV-infected patients were selected, 72 B and 20 non-B subtypes. Regarding the B subtype group, significant kappa values were obtained among all 28 possible combinations between the genotypic predictors evaluated. The best concordance among non-related predictors was observed for webPSSM(SINSI)/Wetcat(PART) (k: 0.771) and webPSSM(SINSI)/geno2pheno (k: 0.574). Conversely, among non-B subtypes, a significative kappa index was only obtained for 13 combinations. Among non-B subtypes, the best concordance values were obtained for webPSSM(X4R5)/Wetcat(PART) (k: 0.600) and webPSSM(SINSI)/Charge rule (k: 0.590). CONCLUSION: A high concordance was observed between different genotypic algorithms to determine viral tropism among HIV-1 B subtypes infected patients, especially between webPSSM(SINSI) and geno2pheno or Wetcat. Conversely, the overall concordance among non-B subtypes was lower. This heterogeneity could be justified by the low prevalence of non B subtypes in the datasets in which the genotypic tropism predictors were trained.

RESUMEN

BACKGROUND: Genotypic tools may allow easier and less expensive estimation of HIV tropism before prescription of CCR5 antagonists compared with the Trofile assay (Monogram Biosciences, South San Francisco, CA, USA). METHODS: Paired genotypic and Trofile results were compared in plasma samples derived from the maraviroc expanded access programme (EAP) in Europe. A new genotypic approach was built to improve the sensitivity to detect X4 variants based on an optimization of the webPSSM algorithm. Then, the new tool was validated in specimens from patients included in the ALLEGRO trial, a multicentre study conducted in Spain to assess the prevalence of R5 variants in treatment-experienced HIV patients. RESULTS: A total of 266 specimens from the maraviroc EAP were tested. Overall geno/pheno concordance was above 72%. A high specificity was generally seen for the detection of X4 variants using genotypic tools (ranging from 58% to 95%), while sensitivity was low (ranging from 31% to 76%). The PSSM score was then optimized to enhance the sensitivity to detect X4 variants changing the original threshold for R5 categorization. The new PSSM algorithms, PSSM(X4R5-8) and PSSM(SINSI-6.4), considered as X4 all V3 scoring values above -8 or -6.4, respectively, increasing the sensitivity to detect X4 variants up to 80%. The new algorithms were then validated in 148 specimens derived from patients included in the ALLEGRO trial. The sensitivity/specificity to detect X4 variants was 93%/69% for PSSM(X4R5-8) and 93%/70% for PSSM(SINSI-6.4). CONCLUSIONS: PSSM(X4R5-8) and PSSM(SINSI-6.4) may confidently assist therapeutic decisions for using CCR5 antagonists in HIV patients, providing an easier and rapid estimation of tropism in clinical samples.

RESUMEN

Objetivo: La preparación del conducto radicular con un solo instrumento con movimiento reciprocante está generando preocupación acerca de su comportamiento en la preparación de los conductos. El propósito de este estudio fue comparar qué sistema (TwistedFiles(R) oReciproc(R)) produce menos transporte radicular en conductos curvos. Metodología: Se utilizaron 40 molares inferiores humanos recién extraídos con curvaturas entre 25 y 35 grados, siguiendo la técnica de Schneider. Los molares fueron divididos aleatoriamente en dos grupos de 20 molares cada uno; Grupo 1: se prepararon usando movimiento de rotación continua con limas Twisted Files(R) mientras que en el Grupo 2 se prepararon con movimiento reciprocante con limas Reciproc(R). Se determinó el transporte del conducto radicular a través de CTScan midiendo la curvatura exterior e interior antes y después de la preparación. Resultados: En ambos grupos se encontró transporte del conducto radicular. Los resultados se analizaron mediante la prueba t de Student. No hubo diferencias significativas en los grados y las direcciones de transporte entre TF y grupos RP (p <.05). Conclusiones: La instrumentación con movimiento reciprocante no aumentó el transporte del conducto radicular cuando se comparacon el movimiento de rotación continua. El movimiento recíproco podría ser un método alternativo en la configuración del conducto radicular


Objective: The single-file root canal instrumentation technique using reciprocating motion is generating concern abou this behavior in root canals preparation. The purpose of this study was to compare which system Twisted Files(R) and Reciproc(R) produces less root transportation in curved root canal. Methodology: 40 extracted human mandibular molars with curvature between 25-35 degrees following Schneider’s technique. All teeth were randomly divided into 2 groups of 20 root canals each. Group 1 were prepared by using continuous rotation motion with Twisted File(R) Group 2 were prepared with reciprocating motion with Reciproc(R) files, the root canal transportation was determined through CT Scan measuring the external and internal curvature before and after preparation. Results: Both studied preparations systems created root canal transportation. The results were analysed by the t Student test. There were no significant differences in both the degrees and directions of transportation between TF and RP groups (P > .05). Conclusions: The reciprocating motion instrumentation did not increased root canal transportation when compared with continuous rotation motion. Reciprocating motion might be an alternative method in root canal shaping

RESUMEN

Antecedentes Las herramientas genotípicas basadas en el análisis de la región V3 de la envuelta viral se perfilan como la alternativa a los ensayos fenotípicos para la determinación del tropismo del VIH por los receptores de quimiocinas CCR5 y CXCR4 en la práctica clínica. Este trabajo evalúa la concordancia entre los distintos algoritmos de interpretación genotípica actualmente disponibles en pacientes VIH infectados con subtipo B versus subtipos no-B .Métodos Se seleccionaron pacientes VIH positivos, procedentes del Complexo Hospitalario Universitario de Santiago de Compostela (CHUS), España. A partir de muestras de plasma, se amplificó y secuenció la región V3 de la envuelta viral. El tropismo viral se determinó usando 8 algoritmos genotípicos distintos. La concordancia entre los distintos predictores se evaluó calculando el índice de concordancia kappa. El subtipo genético fue determinado por análisis filogenético. Resultados Se incluyeron un total de 92 pacientes, 72 infectados por subtipo B y 20 por no-B. En pacientes con subtipo B, se obtuvieron valores significativos de kappa para todas combinaciones posibles (n=28) entre los algoritmos genotípicos analizados. La mejores valores entre predictores no relacionados se obtuvieron para webPSSMSINSI/WetcatPART (k: 0,771) y webPSSMSINSI/geno2pheno (k: 0,574). En subtipos no-B solo se obtuvieron valores significativos para 13 combinaciones, correspondiendo los mejores a PSSMX4R5/WetcatPART (k: 0,600) y PSSMSINSI/Charge rule (k: 0,590) (..) (AU)
