Efficiency of mixed and rigid occlusal stabilization splints: Randomized clinical trial

Abstract Occlusal stabilization splints are the most common treatment for controlling the deleterious effects of sleep bruxism. This study aimed to evaluate the effectiveness of a low-cost, mixed occlusal splint (MOS) compared to that of a rigid splint. A randomized clinical trial was performed on 43 adults of both sexes with possible sleep bruxism and satisfactory dental conditions. They were divided into rigid occlusal splint (ROS) (n = 23) and MOS (n = 20) groups. Masticatory muscle and temporomandibular joint (TMJ) pain intensity (visual analog scale), quality of life (WHOQOL-BREF), indentations in the oral mucosa, anxiety, and depression (HADS), number of days of splint use, and splint wear were evaluated. All variables were evaluated at baseline (T0), 6 months (T6), and 12 months (T12) after splint installation (T0), and splint wear was evaluated at T6 and T12. Student's t-test, Mann-Whitney U test, non-parametric Friedman's analysis of variance for paired samples and pairwise multiple comparisons, Pearson's chi-square test, two-proportion z-test, non-parametric McNemar's and Cochran's Q, and Wilcoxon tests were used (p < 0.05). In both groups, there was a decrease in TMJ pain and pain intensity over time and improvements in the quality of life scores. At T6, there was a higher rate of splint wear in the MOS group than in the ROS group (p = 0.023). The MOS showed a higher rate of wear than the rigid splint but had similar results for the other variables. Therefore, the use of a mixed splint appears to be effective in controlling the signs and symptoms of sleep bruxism.

Factors associated with extreme weight loss behaviors among adolescents of Northeastern Brazil: a hierarchical approach / Comportamentos extremos para perda de peso e fatores associados em adolescentes do Nordeste brasileiro: uma abordagem hierárquica

Abstract The objective of this article is to identify the prevalence and evaluate the factors associated with extreme weight loss behaviors among adolescents of Northeastern Brazil. Cross-sectional study with 2,439 adolescents from Sample 2 (2015) of the National School-based Health Survey. Extreme weight loss behaviors, such as self-induced vomiting, laxative use and use of medicines or formulas (outcome) and independent variables were evaluated using a self-administered electronic questionnaire. The statistical analysis was performed following a hierarchical conceptual model. The prevalence of extreme weight loss behaviors in the sample was 12.1%. Among the factors that showed significant association with the outcome, we emphasize the administration model of the private school (PR = 0.62; CI = 0.46-0.84), bullying related to body appearance and for other reasons (PR = 1.62; CI = 1.19-2.20), forced sexual intercourse (PR = 2.65; CI = 1.90-3.69), insomnia (PR = 1.84; CI = 1.43-2.37), and be perceived as fat or very fat (PR = 1.90; CI = 1.50-2.42). Moderate prevalence of extreme weight loss behaviors was identified among adolescents. Socioeconomic factors, exposure to violence, mental health, and body image were associated with the adoption of these behaviors.

Resumo O objetivo deste artigo é identificar a prevalência e avaliar os fatores associados aos comportamentos extremos para perda de peso em adolescentes do Nordeste brasileiro. Estudo transversal com 2.439 adolescentes da Amostra 2 (2015) da Pesquisa Nacional de Saúde do Escolar. Os comportamentos extremos para perda de peso (desfecho) e as variáveis independentes foram avaliadas por meio de um questionário eletrônico autoaplicável. A análise estatística foi realizada seguindo um modelo conceitual hierárquico. A prevalência de comportamentos extremos para perda de peso na amostra foi de 12,1%. Entre os fatores que mostraram associação significativa com o desfecho, destacam-se a situação administrativa da escola privada (RP = 0,62; IC = 0,46-0,84), ser vítima bullying relacionado à aparência corporal e pelos demais motivos (RP = 1,62; IC = 1,19-2,20), ser forçado a ter relação sexual (RP = 2,65; IC = 1,90-3,69), ter insônia (RP = 1,84; IC = 1,43-2,37) e se autoperceber como gordo ou muito gordo (RP = 1,90; IC = 1,50-2,42). Prevalência moderada de comportamentos extremos para perda de peso foi identificada entre os adolescentes. Os fatores socioeconômicos, de exposição à violência, de saúde mental e da imagem corporal se associaram à adoção de tais comportamentos.

Percepções e Vivências de Psicólogos/as sobre a Punição Física em Crianças / Perceptions and Experiences of Psychologists about Physical Punishment in Children / Percepciones y Experiencias de los Psicólogos/as sobre el Castigo Físico en Niños/as

Este estudo qualitativo e transversal investigou as percepções e vivências dos/as psicólogos/as sobre o uso da punição física em crianças. Participaram do estudo 13 psicólogos/as brasileiros/as, que responderam a um questionário sociodemográfico on-line, um roteiro de entrevista e vinhetas de situação-problema. A análise de conteúdo revelou duas categorias: Ambivalência nas percepções sobre o uso da punição física: A palmada não é uma forma de agressão?; e Reprodução da punição física geração após geração: a forma de educar mudou?. Constataram-se percepções endossando o uso da punição física e experiências pessoais de punição física na infância, mas vários participantes buscam não repetir com os filhos e são desfavoráveis a todos os níveis dessa prática. Participantes favoráveis ao uso, principalmente da palmada, demonstraram desconhecimento da sua ineficácia enquanto método educativo e de seus efeitos prejudiciais. A transgeracionalidade e a naturalização da palmada foram motivos salientados para a persistência do uso da punição física. São necessárias capacitações a psicólogos/as e estudantes sobre os prejuízos e alternativas à punição física em crianças.

This qualitative and transversal work aimed to investigate the perceptions and experiences of psychologists about the use of physical punishment in children. Thirteen Brazilian psychologists participated in the study, who answered a socio-demographic questionnaire, an interview script and problem-situation vignettes online. Content analysis revealed two categories: Ambivalence in perceptions about the use of physical punishment: Isn't spanking a form of aggression? and Reproduction of physical punishment generation after generation: has the way of educating changed? Perceptions endorsing the use of physical punishment and personal experiences of physical punishment in childhood were found, but several participants try not to repeat it with their children and are unfavorable to all levels of this practice. Participants favorable to the use, mainly of spanking, demonstrated ignorance of its ineffectiveness as an educational method and its harmful effects. The transgenerationality and the naturalization of spanking were highlighted reasons for the persistence of the use of physical punishment. Training is needed for psychologists and students on the harm and alternatives to physical punishment in children.

Este estudio cualitativo y transversal tuvo como objetivo investigar las percepciones y experiencias de psicólogos sobre el uso del castigo físico en niños. Participaron del estudio trece psicólogos brasileños, que respondieron un cuestionario sociodemográfico, un guión de entrevista y viñetas de situaciones-problema en línea. El análisis de contenido reveló dos categorías: Ambivalencia en las percepciones sobre el uso del castigo físico: ¿Las nalgadas no son una forma de agresión? y Reproducción del castigo físico generación tras generación: ¿ha cambiado la forma de educar? Se encontraron percepciones que avalan el uso del castigo físico y experiencias personales del castigo físico en la infancia, pero varios participantes intentan no repetirlo con sus hijos y son desfavorables a todos los niveles de esta práctica. Los participantes favorables al uso, principalmente de las nalgadas, demostraron desconocer su ineficacia como método educativo y sus efectos nocivos. La transgeneracionalidad y la naturalización de las nalgadas fueron razones destacadas para la persistencia del uso del castigo físico. Se necesita capacitación para psicólogos y estudiantes sobre el daño y las alternativas al castigo físico en los niños.

Tratamiento cuádruple con doxiciclina, furazolidona, bismuto e inhibidor de bomba de protones sigue siendo efectivo frente al Helicobacter pylori en nuestra población

Nuestro objetivo es determinar si el tratamiento para Helicobacter pylori (HP) con doxiciclina, furazolidona, bismuto y un inhibidor de bomba de protones mantiene su efectividad en nuestra población. Se realizó un estudio retrospectivo, no aleatorio, realizado en una clínica privada de Lima, Perú. Se obtuvo la información de la historia clínica digital. Se incluyó a pacientes con el diagnóstico de infección por HP por biopsia y/o test rápido de la ureasa, obtenidos al realizar una endoscopía entre enero 2017 a octubre 2022. Debían haber recibido el tratamiento cuádruple en estudio o un esquema triple alternativo con amoxicilina, levofloxacino e inhibidor de bomba de protones y tener una prueba de aliento para HP en el lapso de 1 a 6 meses después del tratamiento. El esquema cuádruple con furazolidona logró la erradicación en 117/122 casos (95,9%) mientras que el triple con levofloxacino en 5/16 (31,2%) cuando se usó por 7 dias y en 22/38 (57,9%) cuando se usó por 10 días, siendo las diferencias altamente significativas (p>0,001). En conclusión, el tratamiento cuádruple con furazolidona mostró alta efectividad, mientras que el triple con levofloxacino no alcanzó niveles aceptables.

Our objective is to determine the effectiveness of a therapeutic regimen for helicobacter pylori that includes a proton pump inhibitor, doxycycline, furazolidone and bismuth in our location. We carried out a retrospective study, non-randomized, in a private hospital in Lima, Peru. Patients with biopsy and/or rapid urease test proven helicobacter pylori infection after an endoscopy, from January 2017 to October 2022 were included. They received the therapeutic regimen of the study or an alternative triple regimen with a proton pump inhibitor, amoxicillin and levofloxacin and were followed with a urea breath test within 1 to 6 months upon completion of therapy. The quadruple therapy with furazolidone obtained success in 117/122 cases (95.9%) while the triple therapy with levofloxacin only in 5/16 (31.2%) when used for 7 days and 22/38 (57.9%) when used for 10 days, a statistically significant difference with p<0.001. Conclusion: Quadruple therapy with furazolidone reached high effectiveness in our location, while triple therapy with levofloxacin was not an acceptable alternative.

Malacoplaquia del colon: Rara enfermedad que puede presentarse como un sindrome consuntivo

La malacoplaquia del colon es una causa inusual de diarrea crónica y puede presentarse como una enfermedad consuntiva. A nivel de colon produce lesiones ulceradas y nodulares erosionadas, similares a las de otras enfermedades infecciosas o granulomatosas más comunes. El diagnostico se basa en el estudio anatomopatológico que muestra acúmulos de histiocitos en la lámina propia, en cuyo interior se observan unas inclusiones redondeadas, positivas a la tinción de Von Kossa, denominadas cuerpos de Michaelis-Gutmann. Presentamos el caso de un varón 55 años, sin otras enfermedades asociadas, que debutó con diarrea, baja ponderal y anemia, mostrando una respuesta clínica muy favorable con el uso de antibióticos.

Colonic malacoplakia is an unusual cause of chronic diarrhea, and it may present as a consumptive disease. At the colon, it can induce ulcerative and erosive nodular lesions, that mimic other common granulomatous or infectious diseases. Diagnosis is support in biopsies showing groups of histiocytes, with typical Michaelis-Gutmann inclusions, which are positive with the Von Kossa stain. We present the case of a 55-year-old male, without associated diseases, who presented with diarrhea, weight loss and anemia, showing a very good clinical response to antibiotics.

Scientometric review of research on Neglected Tropical Diseases: a 31-year perspective from the Journal of the Brazilian Society of Tropical Medicine

ABSTRACT Background: To analyze the temporal evolution of research on Neglected Tropical Diseases (NTDs) published by the Journal of the Brazilian Society of Tropical Medicine (JBSTM). Methods: We performed an analysis of the scientific production in JBSTM on NTDs using an advanced search, which included authors' descriptors, title, and abstract, and by combining specific terms for each NTDs from 1991 to 2021. Data related to authors, countries of origin, institutions, and descriptors, were evaluated and analyzed over time. Bibliographic networks were constructed using VOSviewer 1.6.16. Results: The JBSTM published 4,268 scientific papers during this period. Of these 1,849 (43.3%) were related to NTDs. The number of publications on NTDs increased by approximately 2.4-fold, from 352 (total 724) during 1991-2000 to 841 (total 2,128) during 2011-2021, despite the proportional reduction (48.6% versus 39.5%). The most common singular NTDs subject of publications included Chagas disease (31.4%; 581/1,849), leishmaniasis (25.5%, 411/1,849), dengue (9.4%, 174/1,849), schistosomiasis (9.0%; 166/1,849), and leprosy (6.5%, 120/1,849), with authorship mostly from Brazil's South and Southeast regions. Conclusions: Despite the proportional reduction in publications, JBSTM remains an important vehicle for disseminating research on NTDs during this period. There is a need to strengthen the research and subsequent publications on specific NTDs. Institutions working and publishing on NTDs in the country were concentrated in the South and Southeast regions, requiring additional investments in institutions in other regions of the country.

Assessment of the regenerative potential of macro-porous chitosan-calcium simvastatin scaffolds on bone cells

Abstract This study evaluated the bioactive potential of a macro-porous chitosan scaffold incorporated with calcium hydroxide (CH-Ca) and functionalized with bioactive doses of simvastatin (SV) for bone tissue regeneration. Initially, the bioactive dose of SV in osteoblastic cells (SAOS-2) was determined. For the direct contact experiment, SAOS-2 cells were plated on scaffolds to assess cell viability and osteogenic differentiation. The second assay was performed at a distance using extracts from scaffolds incubated in culture medium to assess the effect of conditioned medium on viability and osteogenic differentiation. The initial screening showed that 1 μM SV presented the best biostimulating effects, and this dose was selected for incorporation into the CH-Ca and pure chitosan (CH) scaffolds. The cells remained viable throughout the direct contact experiment, with the greatest cell density in the CH-Ca and CH-Ca-SV scaffolds because of their higher porosity. The CH-Ca-SV scaffold showed the most intense bio-stimulating effect in assays in the presence and absence of osteogenic medium, leading to an increased deposition of mineralized matrix. There was an increase in the viability of cells exposed to the extracts for CH-Ca, CH-SV, and CH-Ca-SV during the one-day period. There was an increase in ALP activity in the CH-Ca and CH-Ca-SV; however, the CH-Ca-SV scaffold resulted in an intense increase in the deposition of mineralized nodules, approximately 56.4% at 7 days and 117% at 14 days, compared with CH (control). In conclusion, functionalization of the CH-Ca scaffold with SV promoted an increase in bioactivity, presenting a promising option for bone tissue regeneration.

Chronic exposure to lipopolysaccharides as an in vitro model to simulate the impaired odontogenic potential of dental pulp cells under pulpitis conditions

Abstract Simulating a bacterial-induced pulpitis environment in vitro may contribute to exploring mechanisms and bioactive molecules to counteract these adverse effects. Objective To investigate the chronic exposure of human dental pulp cells (HDPCs) to lipopolysaccharides (LPS) aiming to establish a cell culture protocol to simulate the impaired odontogenic potential under pulpitis conditions. Methodology HDPCs were isolated from four healthy molars of different donors and seeded in culture plates in a growth medium. After 24 h, the medium was changed to an odontogenic differentiation medium (DM) supplemented or not with E. coli LPS (0 - control, 0.1, 1, or 10 µg/mL) (n=8). The medium was renewed every two days for up to seven days, then replaced with LPS-free DM for up to 21 days. The activation of NF-κB and F-actin expression were assessed (immunofluorescence) after one and seven days. On day 7, cells were evaluated for both the gene expression (RT-qPCR) of odontogenic markers (COL1A1, ALPL, DSPP, and DMP1) and cytokines (TNF, IL1B, IL8, and IL6) and the production of reactive nitrogen (Griess) and oxygen species (Carboxy-H2DCFDA). Cell viability (alamarBlue) was evaluated weekly, and mineralization was assessed (Alizarin Red) at 14 and 21 days. Data were analyzed with ANOVA and post-hoc tests (α=5%). Results After one and seven days of exposure to LPS, NF-κB was activated in a dose-dependent fashion. LPS at 1 and 10 µg/mL concentrations down-regulated the gene expression of odontogenic markers and up-regulated cytokines. LPS at 10 µg/mL increased both the production of reactive nitrogen and oxygen species. LPS decreased cell viability seven days after the end of exposure. LPS at 1 and 10 µg/mL decreased hDPCs mineralization in a dose-dependent fashion. Conclusion The exposure to 10 µg/mL LPS for seven days creates an inflammatory environment that is able to impair by more than half the odontogenic potential of HDPCs in vitro, simulating a pulpitis-like condition.

Antecedentes: La detección y resección de lesiones colónicas elevadas (pólipos) sésiles o planas, con polipectomía clásica o compleja detiene la secuencia adenoma-cáncer. La mucosectomía endoscópica (EMR) fue introducida en los setentas y perfeccionada en los ochentas como un procedimiento avanzado para el tratamiento de pólipos grandes o complejos. Una adecuada realización de la técnica puede evitar procedimientos quirúrgicos mayores. Objetivos: Evaluar los resultados y complicaciones de la técnica de mucosectomía (EMR) realizada por gastroenterólogos-endoscopistas en un centro de referencia del Perú. Revisión de indicaciones, éxito, complicaciones y seguimiento. Material y método: Se realizó un análisis descriptivo, retrospectivo y observacional de pacientes tratados con técnica de mucosectomía endoscópica en un centro de endoscopia de referencia nacional en Lima, Perú, desde enero de 2004 a diciembre de 2018. Se aplicó la técnica de elevación y corte controlado en lesiones polipoideas mayores a 1 cm. Se realizó la resección en bloque en lesiones hasta 3 cms y técnica de "piecemeal" o sacabocado en mayores de 3 cms. Se evaluaron resultados, eventos adversos y recurrencia. Resultados: Se analizaron 756 lesiones en el mismo número de pacientes. Hombres 46.8 % (298) y mujeres 53.2 % (338). La edad promedio fue de 61.9 (rangos 37-91). El tamaño promedio de las lesiones fue de 20,3 mm (10 - 50 mm). El tiempo promedio por procedimiento fue de 46 minutos (rango 20-123 minutos). Se logró resección en bloque en 78.04 % de pólipos (590 lesiones). Se realizó técnica sacabocado en 166 (21.96 %) lesiones. La tasa de complicaciones en nuestra serie fue del 6.74 %, todos manejados endoscópicamente más tratamiento conservador médico sin cirugía. El seguimiento promedio fue de 18 meses (3 - 24 meses) y la tasa global de recidiva local fue de 2.49 %. El tratamiento quirúrgico post procedimiento y con pieza analizada se indicó en 15 casos por adenomas avanzados con adenocarcinoma intramucoso bien diferenciado (ADCA-IM). A los 12 meses, 13 de 15 recidivas fueron tratadas endoscópicamente y 2 casos refractarios fueron operados. Conclusiones: La mucosectomía (RME ó EMR) es un procedimiento que, realizado por endoscopistas-gastroenterólogos bien entrenados muestra baja tasa de recurrencia y complicaciones aisladas permitiendo la obtención de adecuado material para el estudio anátomo-patológico y reduciendo necesidad de cirugía abierta o laparoscópica.

Background: Detection and resection of colonic polypoid sessile and flat lesions, prevents the development of colon cancer. Endoscopic mucosal resection (EMR) has emerged in the 70´s and improved in the 80´s, as an alternative treatment of this lesions and is considered the procedure of choice nowadays, being able to avoid major surgical procedures. Objectives: Evaluation of the results and complications of the technique by endoscopists of a reference center. Review of indications and limitations of the technique. Material and methods: Descriptive, retrospective and observational analysis of patients treated with endoscopic mucosal resection technique at a referral center in Lima, Peru, between January 2004 and December 2018. EMR Technique was used in polypoid lesions greater than 1 cm. The bloc resection and the piecemeal resection technique was used for those lesions up to 3 cm and more. We evaluated complications and results according to the technique as recurrence rate, performing tracking in all cases with endoscopic follow up. Results: 756 lesions and patients (338 women and 298 men) The average age was 61.9 years (37-91 years) and the average lesion size of 20.3 mm (10-50 mm). En bloc or one-piece resection was performed in 78.04 %(590) and piece meal in 21.96%(166) achieving endoscopic and pathological resection. The complication rate in our series was 6.74% and managed endoscopically and with conservative measures and no surgery. Mean follow-up was 18 months (3-24 months) and overall local recurrence rate was 2.49%. After-procedure, additional surgical treatment was performed in 15 cases with pathologic piece report and intramucous adenocarcinoma (IM-ADCA). 13 of 15 local recurrences at 12 months follow up were treated endoscopically and 2 had surgical treatment. Conclusions: Endoscopic mucosal resection (EMR) or Mucosectomy is a technique performed by experts endoscopists and shows low rates of recurrence and complications with suitable material for pathologic examination. It reduces open and laparoscopic surgery.

Pro-inflammatory mediators expression by pulp cells following tooth whitening on restored enamel surface

Abstract This paper aimed to assess the influence of adhesive restoration interface on the diffusion of hydrogen peroxide (H2O2), indirect toxicity, and pro-inflammatory mediators expression by odontoblast-like cells, after in-office tooth whitening. Dental cavities prepared in bovine enamel/dentin discs were adhesively restored and subjected or not to hydrolytic degradation (HD). A whitening gel with 35% H2O2 (WG) was applied for 45 min onto restored and non-restored specimens adapted to artificial pulp chambers giving rise to the groups: SD- intact discs (control); SD/HP- whitened intact discs; RT/HP- restored and whitened discs; and RT/HD/HP- restored and whitened discs subjected to HD. The extracts (culture medium + WG components diffused through enamel/dentin/restoration interface) were collected and applied to odontoblast-like MDPC-23 cells. The study evaluated the amount of H2O2 in the extracts, as well as the cell viability (CV), cell morphology (CM), and gene expression of inflammatory mediators (TNF-α and COX-2) by the pulp cells exposed to the extracts (ANOVA and Tukey tests; 5% significance). All whitened groups presented lower CV than SD (control; p<0.05). The highest CV reduction and gene expression of TNF-α and COX-2 was observed in the RT/HD/HP group in comparison with SD/HP and RT/HP (control; p<0.05). CM alterations occurred in all whitened groups. The intensity of these cell side effects was directly related with the amount of H2O2 in the extracts. We concluded that adhesive restoration of dental cavity increases the H2O2 diffusion after in-office whitening, enhancing the indirect toxicity of this therapy and trigger pro-inflammatory overexpression by MDPC-23 cells.

Resumo Este trabalho teve como objetivo avaliar a influência da interface de uma restauração adesiva na difusão do peróxido de hidrogênio (H2O2), toxicidade indireta e expressão de mediadores pró-inflamatórios por células odontoblastóides, após clareamento dental em consultório. Cavidades dentárias preparadas em discos de esmalte / dentina foram restauradas com adesivo e submetidas ou não à degradação hidrolítica (HD). Um gel clareador com 35% H2O2 (WG) foi aplicado por 45 min em discos restaurados e não restaurados adaptados às câmaras pulpares artificiais dando origem aos grupos: SD- discos intactos (controle); SD / HP - Discos intactos clareados; RT / HP - discos restaurados e clareados; e RT / HD / HP - discos restaurados, clareados e submetidos a HD. Os extratos (meio de cultura + componentes WG difundidos através da interface esmalte/dentina/restauração) foram coletados e aplicados em células odontoblastóides MDPC-23. Foi avaliada a quantidade de H2O2 nos extratos, bem como a viabilidade (CV), morfologia (CM) e expressão gênica de mediadores inflamatórios (TNF-α e COX-2) pelas células pulpares expostas aos extratos (ANOVA e testes de Tukey; 5% de significância). Todos os grupos clareados apresentaram menor CV do que SD (controle; p <0,05). A maior redução CV e expressão gênica de TNF-α e COX-2 foi observada no grupo RT / HD / HP em comparação com SD / HP e RT / HP (controle; p <0,05). Alterações na CM ocorreram em todos os grupos clareados. A intensidade desses efeitos celulares teve relação direta com a quantidade de H2O2 nos extratos. Concluímos que a presença de uma cavidade contendo restauração adesiva aumenta a difusão de H2O2 após o clareamento em consultório, o que, por sua vez, aumenta a toxicidade indireta dessa terapia e desencadeia a expressão de mediadores pró-inflamatórios pelas células pulpares MDPC-23.

C-reactive protein for the diagnosis and prognosis of visceral leishmaniasis caused by Leishmania infantum

Acute-phase reaction (APR) and its marker C-reactive protein (CRP) are heightened in some infectious diseases. APR may contribute to clinical manifestations of systemic inflammation such as hemorrhages, anemia and edema. These symptoms are shared by visceral leishmaniasis (VL), a disease caused by the protozoa Leishmania infantum and L. donovani. The former is zoonotic, hitting mostly children and the immunosuppressed, with higher mortality. As APR and CRP have not been studied in VL caused by L. infantum, we decided to investigate their role as diagnostic and prognostic tools in Brazil. We measured CRP in 136 patients before the treatment of VL and 128 who survived and returned 30 days later and compared it to the clinical presentation, HIV status, and disease severity. Sensitivity for the disease was 97.8% (95%CI: 93.7 - 99.5) and specificity was 85.9% (95%CI: 78.7 - 91.0) with the cut-off of 10mg/L. There was no association of CRP concentration with demographic, clinical and laboratory data. The correlation between pre-and post-treatment levels existed but was poor. Marginal association with the presence of parasites in the bone marrow and death was noticed. The role of APR in the pathogenesis of VL and disease severity remains to be explored. However, the study reveals the significant role of CRP for VL caused by L. infantum and should be routinely required for the diagnosis and follow-up.

ABSTRACT Objective. To develop an evidence map on visceral leishmaniasis prevention, control, diagnosis, treatment, and prognosis. Methods. Systematic reviews on visceral leishmaniasis were searched using MEDLINE/PubMed and Virtual Health Library. After selection, each included systematic review was assessed, characterized, and categorized by intervention type and by outcomes, according to the methodology offered by the PAHO/WHO Latin American and Caribbean Center on Health Sciences Information (BIREME). The methodological quality was assessed using the AMSTAR2 tool to determine the confidence level of the evidence obtained. Results. Among the prevention and control interventions, insecticide spraying, bednets, dog collars, and dog culling were the most assessed, emphasizing that insecticidal dog collars can reduce visceral leishmaniasis incidence in dogs. Regarding diagnosis, polymerase chain reaction (PCR), rK39 immunochromatographic test (rK39 ICT), and direct agglutination test (DAT) presented high sensitivity and specificity. As for treatment, pentavalent antimonials and amphotericin B were the most analyzed drugs and showed therapeutic success; however, serious adverse events can occur due to their use. The prognostic factors identified were anemia, edema, bleeding, jaundice, age, and HIV coinfection. Conclusions. The evidence map developed shows rK39 ICT and DAT as promising diagnostic alternatives and reinforces the efficacy of liposomal amphotericin B and pentavalent antimonials. Insecticide-impregnated dog collars appear as a promising measure for the control of visceral leishmaniasis, but there is also a need for future studies and reviews with higher methodological quality, especially on prevention and control interventions.

RESUMEN Objetivo. Elaborar un mapa de evidencia sobre la prevención, el control, el diagnóstico, el tratamiento y el pronóstico de la leishmaniasis visceral. Métodos. Se realizaron búsquedas de revisiones sistemáticas sobre la leishmaniasis visceral en MEDLINE/PubMed y la Biblioteca Virtual en Salud. Tras la selección, cada revisión sistemática incluida fue sometida a evaluación, caracterización y categorización según tipo de intervención y resultados, de acuerdo con la metodología ofrecida por el Centro Latinoamericano y del Caribe de Información en Ciencias de la Salud de la OPS/OMS (BIREME). La calidad metodológica se evaluó con la herramienta AMSTAR2 para determinar el nivel de confianza de la información obtenida. Resultados. Entre las intervenciones de prevención y control, las más evaluadas fueron la fumigación con insecticidas, los mosquiteros, los collares para perros y el sacrificio de perros y se hizo hincapié en que los collares insecticidas para perros pueden reducir la incidencia de leishmaniasis visceral en perros. En cuanto al diagnóstico, la reacción en cadena de la polimerasa (PCR, por su sigla en inglés), la prueba inmunocromatográfica rK39 (rK39 ICT) y la prueba de aglutinación directa (DAT, por su sigla en inglés) mostraron alta sensibilidad y especificidad. Con respecto al tratamiento, los fármacos más analizados que arrojaron éxito terapéutico fueron los antimoniales pentavalentes y la anfotericina B; sin embargo, su uso puede provocar efectos adversos graves. Los factores pronósticos que se identificaron fueron anemia, edema, sangrado, ictericia, edad y coinfección por el VIH. Conclusiones. El mapa de evidencia elaborado presenta la prueba inmunocromatográfica rK39 y la prueba de aglutinación directa como alternativas diagnósticas prometedoras, y consolida la eficacia de la anfotericina B liposomal y los antimoniales pentavalentes. Los collares de perro impregnados de insecticida parecen ser una medida prometedora para el control de la leishmaniasis visceral, si bien también son necesarios estudios y revisiones adicionales de mayor calidad metodológica, especialmente sobre intervenciones de prevención y control.

RESUMO Objetivo. Desenvolver um mapa de evidências de prevenção, controle, diagnóstico, tratamento e prognóstico da leishmaniose visceral. Métodos. Foram realizadas buscas por revisões sistemáticas sobre leishmaniose visceral no MEDLINE/PubMed e na Biblioteca Virtual em Saúde. Após a seleção, cada revisão sistemática incluída foi avaliada, caracterizada e classificada por tipo de intervenção e por desfechos, de acordo com a metodologia oferecida pelo Centro Latino-Americano e do Caribe de Informação em Ciências da Saúde (BIREME) da OPAS/OMS. A qualidade metodológica foi avaliada utilizando a ferramenta AMSTAR2 para determinar o nível de confiança das evidências obtidas. Resultados. Entre as intervenções de prevenção e controle, pulverização com inseticida, mosquiteiros, coleiras para cães e abate de cães foram as mais frequentemente avaliadas, com destaque para as coleiras inseticidas na redução da incidência de leishmaniose visceral em cães. Quanto ao diagnóstico, a reação em cadeia da polimerase (PCR), o teste imunocromatográfico rK39 (rK39 ICT) e o teste de aglutinação direta (DAT, sigla em inglês para direct agglutination test) apresentaram alta sensibilidade e especificidade. Em relação ao tratamento, os antimoniais pentavalentes e a anfotericina B foram os medicamentos mais analisados e demonstraram sucesso terapêutico, embora seu uso possa resultar em eventos adversos graves. Os fatores prognósticos identificados foram anemia, edema, sangramento, icterícia, idade e coinfecção com HIV. Conclusões. O mapa de evidências desenvolvido mostra o rK39 ICT e o DAT como alternativas promissoras para o diagnóstico e reforça a eficácia da anfotericina B lipossomal e dos antimoniais pentavalentes. As coleiras impregnadas com inseticida aparecem como medida promissora para o controle da leishmaniose visceral, mas estudos e revisões futuras com mais qualidade metodológica, especialmente sobre intervenções de prevenção e controle, são necessários.

Resultados funcionales para lesiones completas del manguito rotador con reparación artroscópica mediante fila simple en pacientes con compensación laboral / Functional outcomes for rotator cuff complete tears arthroscopically repaired using simple row suture in worker population

Introducción: El objetivo de este trabajo es valorar los resultados funcionales, porcentaje de re-roturas y tiempo de reintegro laboral en pacientes con lesiones completas del manguito rotador (MR) reparadas artroscópicamente con fila simple.Materiales y métodos: se valoraron en forma retrospectiva ciento siete pacientes. Se incluyeron las lesiones completas tipo 1 y 2 de la clasificación Davidson y Burkhart, laborales, agudas. Se excluyeron lesiones parciales, masivas (mayores a 3 cm), evolucionadas más de seis meses, o que requirieron tratamientos adicionales. Se utilizaron para la valoración: Simple Shoulder Test (SST), Escala Visual Analógica (EVA), American Shoulder and Elbow Surgeons (ASES). En los casos de re-rotura se compararon los resultados finales para ambos grupos mediante Quick Disabilities of the Arm, Shoulder and Hand (QDASH).Resultados: con un seguimiento de 37.8 meses se obtuvieron los siguientes datos: scores SST 8.2 (68.8 ± 2.9%), EVA para valoración del dolor, el resultado fue 93.3% con dolor leve; ASES, la media fue 89%. Porcentaje de re-roturas: 7.5%. QDASH se diferenció en pacientes sin re-roturas 24.1 ± 2.4% y en los casos con re-rotura, 60.2 ± 4.1%. La media de tiempo al reintegro laboral fue de 7.5 ± 0.3 meses. Conclusión: consideramos que la técnica fila simple es una opción válida que nos permite obtener buenos resultados funcionales en lesiones seleccionadas, agudas, móviles de hasta 3 cm, incluso en pacientes con compensación laboral

Introduction: The objective of this study is to assess the functional results, the percentage of re-tears and the time to return to work, in patients with complete tears of the rotator cuff arthroscopically repaired using simple row suture.Materials and methods: one hundred and seven patients were retrospectively evaluated. Complete acute tears types 1 and 2 of the Davidson and Burkhart classification, in workers, were included. Partial, massive tears (greater than 3 cm), evolving for more than six months, or requiring additional treatments, were excluded. The following scores were used for the assessment of results: the Simple Shoulder Test (SST), the Visual Analog Scale (VAS) and the scale of the American Shoulder and Elbow Surgeons Society (ASES).Results: with a follow-up of 37.8 months, the following results were obtained: SST scores was 8.2 (68.8 ± 2.9%), VAS used for pain assessment was 93.3%, and the mean ASES was 89%. The percentage of re-tears was 7.5%. The QDASH differed in patients without re-rupture 27 ± 2.5% from the cases of re-rupture 60.2 ± 4.1%. Conclusion: we considered that the single row suture technique performed arthroscopically is a valid option that allows to obtain good functional results in selected acute rotator cuff injuries of up to 3 cm in worker population

Association between calcium/magnesium ratio and insulin resistance in women with obesity and normal-weight women

ABSTRACT The aim of this study was to evaluate the association between the calcium/magnesium (Ca/Mg) ratio and insulin resistance in women with obesity and normal-weight women. This was a cross-sectional study with 128 women (62 women with obesity and 66 normal-weight women). We measured dietary minerals intake and analyzed magnesium and calcium biomarkers. Ca/Mg ratio in diet, plasma and urine were calculated. We have evaluated glycemic parameters. Women with obesity had low dietary magnesium, reduced plasma and erythrocyte magnesium concentrations, and elevated urinary magnesium excretion. Plasma calcium concentration was lower and urinary calcium excretion was higher in patients with obesity than in the normal-weight group. Dietary magnesium and calcium intake per kilogram of body weight per day was lower in obese women than in the control group. Ca/Mg ratio in plasma and urine were elevated in women with obesity. We found a significant correlation among magnesium biomarkers and calcium parameters. Ca/Mg ratio seems to be associated with insulin resistance in obese women.

RESUMEN El objetivo de este estudio fue evaluar la asociación entre la relación Ca/Mg y la resistencia a la insulina en mujeres con obesidad y en mujeres con peso normal. El diseño del estudio fue transversal y participaron 128 mujeres (62 mujeres con obesidad y 66 mujeres con peso normal). Se analizó la ingesta de minerales en la dieta y se realizaron análisis de biomarcadores de magnesio y calcio. Se calculó la relación Ca/Mg en dieta, plasma y orina y se evaluaron los parámetros glicémicos. Las mujeres con obesidad tenían niveles bajos de magnesio en la dieta, concentraciones reducidas de magnesio en plasma y eritrocitos, y excreción urinaria de magnesio elevada. La concentración plasmática de calcio fue menor en pacientes con obesidad, y la excreción urinaria de calcio fue mayor que en el grupo de mujeres con peso normal. La ingesta dietética de magnesio y calcio por kilogramo de peso corporal por día fue menor en las mujeres con obesidad, que en el grupo control. La relación Ca/Mg en plasma y orina estaba elevada en mujeres con obesidad. Se encontró una correlación significativa entre los biomarcadores de magnesio y los parámetros de calcio. La relación Ca / Mg parece estar asociada con la resistencia a la insulina en mujeres con obesidad.

Perspectiva do gestor frente ao alcoolismo no contexto laboral da construção civil / Managerial perspectives on alcoholism amongst construction workers / Perspectiva del gestor sobre el alcoholismo en el contexto laboral de la construcción civil

O uso de bebidas alcoólicas é um problema de saúde pública que afeta, sobremaneira, a permanência e o desempenho de indivíduos no campo profissional. Diante dessa realidade, este trabalho objetivou analisar como os gestores atuam diante de contextos organizacionais em que há colaboradores alcoolistas. Para tanto se estudou, especificamente, os profissionais da construção civil no município de Passo Fundo, Rio Grande do Sul, Brasil. Metodologicamente realizou-se um estudo descritivo, de abordagem quantitativa e de corte transversal, aplicando-se questionários a 50 gestores de empresas do ramo. Os resultados demonstraram que, na perspectiva dos gestores, o consumo abusivo de álcool é uma doença e os casos nesse contexto laboral demonstraram a necessidade de ações internas destinadas ao uso consciente de bebidas alcoólicas. Portanto, os participantes da pesquisa consideraram o espaço laboral apropriado para a promoção de práticas preventivas; que, no entanto, acabam não sendo efetivadas.

As alcoholic beverage consumption represents an important public health issue, and is strongly tied to poor performance and permanence of individuals in professional fields, the present study's authors sought to analyse how managers act in the face of organizational contexts in which alcoholic employees are present. Professionals in civil construction from the municipality of Passo Fundo, State of Rio Grande do Sul, Brazil, were specifically targeted for study. Through a quantitative and cross-sectional approach, a descriptive study was carried out by applying questionnaires to 50 managers of companies in the industry. From the managers' perspective, alcohol abuse is a disease. Cases in this work context demonstrate the need for internal actions aimed at limiting the conscious use of alcoholic beverages. While respondents considered the workplace to be an appropriate place to promote preventative measures against alcoholism, this was largely not carried out in practice.
