Abstract Introduction: A recent revision of the generic classification of the Trochilidae based on DNA sequences revealed many inconsistencies with the current generic classification, largely based on plumage characters subject to homoplasy, especially in the Trochilini, the largest tribe. A thorough generic reorganization brought the classification into accord with the phylogeny, but due to lack of genetic data, two species remained unclassified. One of these was the Mangrove Hummingbird, "Amazilia" boucardi, endemic to Costa Rica and included in the IUCN red list of threatened species. Objective: To obtain molecular evidence to clarify the generic relationships of "A." boucardi. Methods: We isolated DNA from tissues of this species and amplified 4 nuclear and 4 mitochondrial fragments and compared these with homologous fragments from 56 species in the Trochilini, constructing phylogenetic trees with maximum likelihood and Bayesian methods. Results: Our phylogenetic analyses confirmed the placement of boucardi in the Trochilini and definitely excluded it from Amazilia but placed it with high confidence in the genus Chrysuronia Bonaparte, 1850, within which its closest relative is C. coeruleogularis, which also inhabits mangroves. Conclusions: Our genetic data based on nuclear and mitochondrial regions clearly indicate the relationship of A. boucardi and L. coeruleogularis. Moreover, it is also supported by their habitat distribution in the mangroves of the Pacific coast of Costa Rica and Western Panama. Therefore, we suggested to exclude A. boucardi as "incertae sedis".
Resumen Introducción: Una revisión reciente de la clasificación de la familia Trochilidae con base en secuencias de ADN demostró muchas incongruencias con la clasificación genérica previa, que había sido hecho con base en caracteres del plumaje muy sujetos a homoplasia, especialmente en la tribu más grande, Trochillini. Una reorganización de los géneros logró llevar su clasificación genérica a la concordancia con la filogenia, pero debido a la ausencia de datos genéticos, dos especies permanecieron sin clasificar. Una de estas fue el colibrí de manglar Amazilia boucardi, una especie endémica de Costa Rica, considerada como amenazada en la lista roja de la UICN. Objetivo: Obtener evidencia molecular para esclarecer las relaciones genéricas de A. boucardi. Métodos: Se aisló ADN de tejidos de esta especie y se amplificaron 4 fragmentos de ADN del núcleo y 5 de la mitocondria, y se compararon con fragmentos homólogos de 56 especies en la tribu Trochillini, generando árboles filogenéticos con métodos de máxima verosimilitud y bayesiano. Resultados: Los análisis filogénticos obtenidos confirmaron la ubicación de boucardi en Trochilini y definitivamente la excluyó del género Amazilia, pero la ubicó con un alto grado de confianza en el género Chrysuronia Bonaparte, 1850, dentro los cuales su pariente más cercano es C. coeruleogularis, que también habita manglares. Conclusiones: Nuestros datos genéticos basados en regiones nucleares y mitocondriales indican claramente la relación entre A. boucardi and L. coeruleogularis. Es más, lo anterior se sustenta por su distribución en los manglares de la costa Pacífica de Costa Rica y oeste de Panamá. Por lo tanto, sugerimos excluir a A. boucardi como "incertae sedis".

Abstract Background: Pemphigus constitutes a group of autoimmune bullous diseases. A reduction in the incidence of endemic pemphigus foliaceus and an increase in pemphigus vulgaris has been described, but there are no studies in Minas Gerais that address the subject. Objective: To describe the epidemiological and clinical profile of patients with pemphigus treated at the Dermatology Service of a public University Hospital in the state of Minas Gerais, Brazil. Methods: An observational, descriptive, and cross-sectional study was carried out of cases of endemic pemphigus foliaceus and pemphigus vulgaris, for a period of six months. A questionnaire was filled out with epidemiological and clinical data on the disease. Results: A total of 122 patients were included in the study, 64 with endemic pemphigus foliaceus and 58 with pemphigus vulgaris. When comparing patients with endemic pemphigus foliaceus and those with pemphigus vulgaris, a statistical difference was observed between the median age of initial disease manifestation (p = 0.001), patient occupation (p = 0.010), area of residence (p = 0.000), forests (p = 0.000) and rivers/streams close to the dwelling (p = 0.001) and the number of systemic medications required to control the disease (p = 0.002). When comparing patients with endemic pemphigus foliaceus to those evaluated in a study carried out at the same service in 2008, there was a statistical difference in the area of residence (p = 0.030). Study limitations: The assessed population comes from a tertiary care service that is not a reference for the entire state. Conclusions: Patients with endemic pemphigus foliaceus and pemphigus vulgaris maintain statistically significant differences regarding their main variables in the literature, such as age and area of residence. Historically, there has been a reduction in cases of endemic pemphigus foliaceus and an increase in cases of pemphigus vulgaris in this population.

ABSTRACT The Maricá Environmental Protection Area (RJ, Southeastern Brazil) is predominantly occupied by the restinga ecosystem. Two broad inventories of insect galls and several contributions to the taxonomical knowledge of the local gall-inducing fauna have been done since 1992. The present study aims to compile literature data, compare them with data from recent collections and evaluate the similarity between the gall-inducing insects from this area and those from other restingas, using the Sorensen's index. Field work was carried out from April 2021 to March 2022, in a total of 14 expeditions. All voucher material was deposited in the Entomological Collection of Museu Nacional/UFRJ. According to literature compilation, the Environmental Protection Area of Maricá (MEPA) hosts 108 gall-inducing species, 83.3% were collected again. Twenty-three gall morphotypes were found for the first time in the study area as well as two host plants, Schwartzia brasiliensis (Marcgraviaceae) and Lantana fucata (Verbenaceae). All Brazilian restingas have low similarity with MEPA, which shows that this restinga is unique in the composition of the gall-inducers. MEPA includes 63 endemic species and morphospecies of cecidogenous insects. Nyctaginaceae, Boraginaceae, and Erythroxylaceae showed the greatest average of inducers by plant species. However, these taxa are not the best represented in MEPA, but they include super hosts, which explains their highest value. The family Myrtaceae shelters the greatest richness of gall-inducing insects and the greatest richness of host plant species. A new case of inquilinism was observed in galls on Neomitranthes obscura (Myrtaceae).

Abstract The Río San Pedro and Río La Pasión lie within the Usumacinta River Basin, a globally significant center of freshwater fish diversity. Both rivers are listed among Central America's top 50 regions for conserving freshwater biodiversity. This study presents an updated checklist of 70 fish species, of which six are non-native to the Usumacinta River Basin. From these species, 69 are reported from the Río La Pasión and 56 reported from the Río San Pedro, representing higher species richness than previously reported. The checklist derives from a systematic survey of fishes conducted in 2019 and records available in public databases and published literature. Seventy-eight percent of the species were reported in both rivers, and Cichlidae and Poeciliidae had the most species. Secondary species represent 59% of the species reported, followed by peripheral species with 22% of the species. The species with highest fidelity in Río La Pasión were the armored catfish Pterygopichthys spp. and the livebearer Gambusia sexradiata; and the cichlids Thorichthys meeki and Oscura heterospila had highest fidelity in the Río San Pedro. Thorichthys helleri was widely distributed in both rivers. According to the IUCN Red List of Threatened Species, there are four species classified as Vulnerable in Río La Pasión. However, 62% of the species are of Least Concern, 25% of the species are Data Deficient, and 6% are listed as Not Evaluated. More research is needed to document the status of the fish fauna, and improved habitat protection is required to conserve stocks.
Resumen El río San Pedro y el río La Pasión se encuentran dentro de la cuenca del río Usumacinta, un centro de diversidad de peces de agua dulce de importancia mundial. Ambos ríos figuran entre las 50 regiones principales de América Central para conservar la biodiversidad de agua dulce. Este estudio presenta un listado actualizado de 70 especies de peces, de las cuales 6 son especies no nativas para la cuenca del Río Usumacinta. De estas especies, 69 se reportan para el Río La Pasión y 56 para el río San Pedro, lo que representa una riqueza de especies más alta que la reportada previamente. La lista de verificación se deriva de un muestreo sistemático de peces realizado en 2019 y registros disponibles en bases de datos públicas y literatura publicada. El 78% de las especies se reportan en ambos ríos, siendo Cichlidae y Poeciliidae las familias con mayor riqueza. Las especies con mayor fidelidad en Río La Pasión fueron el bagre acorazado Pterygopichthys spp. y el pez vivíparo Gambusia sexradiata; y los cíclidos Thorichthys meeki y Oscura heterospila tuvieron mayor fidelidad en el Río San Pedro. Thorichthys helleri se distribuyó ampliamente en ambos ríos. Según la Lista Roja de Especies Amenazadas de la UICN, existen cuatro especies clasificadas como Vulnerable en el Río La Pasión. Sin embargo, el 62 % de las especies son de Preocupación Menor, el 25 % de las especies tienen Datos Insuficientes y el 6 % se enumeran como No Evaluadas. Se necesita más investigación para documentar el estado de la fauna de peces, y se requiere una mejor protección del hábitat para conservar las poblaciones.
Résumé
ABSTRACT Background: Malaria is a major global public health issue with varying epidemiologies across countries. In Colombia, it is a priority endemic-epidemic event included in the national public health policy. However, evidence demonstrating nationwide variations in the disease behavior is limited. This study aimed to analyze changes in the levels and distribution of endemic-epidemic malaria transmission in the eco-epidemiological regions of Colombia from 1978 to 1999 and 2000 to 2021. Methods: We conducted a comprehensive time-series study using official secondary data on malaria-associated morbidity and mortality in Colombia from 1978 to 2021. Temporal-spatial and population variables were analyzed, and the absolute and relative frequency measures of general and regional morbidity and mortality were estimated. Results: We observed an 18% reduction in malaria endemic cases between the two study periods. The frequency and severity of the epidemic transmission of malaria varied less and were comparable across both periods. A shift was observed in the frequency of parasitic infections, with a tendency to match and increase infections by Plasmodium falciparum. The risk of malaria transmission varied significantly among the eco-epidemiological regions during both study periods. This study demonstrated a sustained decrease of 78% in malarial mortality. Conclusions: Although the endemic components of malaria decreased slightly between the two study periods, the epidemic pattern persisted. There were significant variations in the risk of transmission across the different eco-epidemiological regions. These findings underscore the importance of targeted public health interventions in reducing malarial morbidity and mortality rates in Colombia.

Introducción: se vive una crisis de confianza en la ciencia y una época de menosprecio a los conocimientos y evidencias. Las opiniones de los líderes políticos y otras figuras públicas ajenas a los problemas de salud tienen una mayor consideración y peso que los juicios emitidos por los expertos. Una evidencia que demuestra la debilidad de México en el campo de la salud son dos hechos en los cuales las autoridades del país son los culpables que son: la desaparición del Seguro Popular y la pobre respuesta a la pandemia de COVID-19. Conclusiones: la pandemia no termina por decreto, se logrará con cuidados y prevención realizada por el gobierno, instituciones y personal de salud y la sociedad (AU)
Introduction: we are living through a crisis of confidence in science and an era of disregard for knowledge and evidence. The opinions of political leaders and other public figures who are not involved in health problems are given greater consideration and weight than the judgments made by experts. Evidence that demonstrates Mexico's weakness in the field of health are two facts in which the country's authorities are to blame: the disappearance of Seguro Popular and the poor response to the COVID-19 pandemic. Conclusions: the pandemic does not end by decree, it will be achieved with care and prevention carried out by the government, health institutions and personnel and society (AU)

Purpose: Leptospirosis is a waterborne zoonotic disease that primarily causes systemic illness, followed by uveitis. After heavy flooding in Madurai district, an epidemic outbreak of systemic and ocular leptospirosis occurred in 1994. Our data shows a transition to endemicity after each epidemic. Aim: The aim of this study is to report the clinical signs, epidemic outbreaks, and persistent endemicity of leptospiral uveitis, as well as the diagnostic dilemmas associated with it. Methods: A retrospective analysis of clinical signs was conducted using medical records of leptospiral uveitis patients over a period of 27 years (1994–2020) in a tertiary care eye hospital. The clinical workup of uveitis included a detailed clinical history, systemic, and ophthalmic examination. Microagglutination tests (MATs) was done at the Centers for Disease Control and Prevention (CDC) in Atlanta and later in our regional laboratory. Serum samples were collected from human systemic leptospirosis cases and a small group of animals in and around Madurai. Results: The first epidemic outbreak resulted in 200 seropositive patients. Subsequent epidemic outbreaks occurred in 1997, 1998, 2001, 2005, and 2012, with Madurai experiencing multiple outbreaks. However, the disease remained endemic, with 25–50 patients being observed per year in between the peaks. Ocular examination revealed acute non?granulomatous uveitis (94.9%), pan uveitis (59.8%), vitreous inflammatory reaction (55.4%), retinal vasculitis (29.5%), disc hyperemia (20.9%), and hypopyon. (16.2%). New serovars emerged every year, resulting in decreased sensitivity of the MAT. Over time, the MAT started to miss diagnoses. Conclusion: The persistent endemicity of leptospiral uveitis emphasizes the need for accessible diagnostic tests. The low performance of the MAT can be attributable to the use of an older panel. The incorporation of new isolates in the MAT by a national laboratory will improve the accuracy of diagnosis

Introducción: La leishmaniasis visceral es una enfermedad zoonótica, transmitida por vectores del género Lutzomyia, de distribución en 98 países, incluyendo Colombia y que puede ocasionar un cuadro clínico grave, que en ausencia de tratamiento puede ser fatal. Objetivo: Determinar los conocimientos, actitudes y prácticas (CAP) adquiridas sobre vectores, reservorios y características de la Leishmaniasis visceral en las comunas 8, 9 y 10 de Neiva (Huila) en 2019. Materiales y métodos: Se realizó un estudio descriptivo de corte transversal en el período de junio a diciembre de 2019, en el que se muestrearon tres comunas (8, 9 y 10), en un total de 30 barrios de la ciudad de Neiva-Huila. Se aplicaron 385 encuestas tipo CAP, con un margen de error de 5 % y una confiabilidad de 95 %. Se incluyeron personas adultas de 18 años o más (267 mujeres y 117 hombres), que voluntariamente desearon participar, con previo consentimiento informado. Resultados: Según la información analizada, se determinó que 77 % de los encuestados no conoce la leishmaniasis visceral, 52 % no la identifican como una enfermedad zoonótica, 82 % no conocen el agente causal y 44 % no tienen claridad sobre los síntomas que se presentan en humanos. Conclusiones: Aunque se han realizado campañas preventivas en las comunas afectadas, el nivel de conocimiento sobre la enfermedad, el vector, el reservorio y las prácticas preventivas específicas para contrarrestar la leishmaniasis visceral son poco conocidos en la población de estudio, a pesar de que las prácticas y actitudes identificadas son positivas.
Introduction: Visceral leishmaniasis is a zoonotic disease transmitted by vectors of the Lutzomyia genus, distributed in 98 countries, including Colombia, which can cause a serious clinical picture that, in the absence of treatment, can be fatal. Objective: To determine the knowledge, attitudes, and practices (KAP) acquired on vectors and reservoirs, as well as the characteristics of visceral Leishmaniasis in communes 8, 9 and 10 of the city of Neiva in 2019. Material and Methods: A descriptive cross-sectional study was carried out from June to December 2019. Three communes (8, 9 y 10) were sampled from a total of 30 neighborhoods of the city of Neiva - Huila. In addition, 385 CAP-type surveys were applied, with a margin of error of 5% and a reliability of 95%. People aged 18 years or older (267 women and 117 men) who voluntarily wished to participate, with prior informed consent, were included. Results: According to the analyzed information, it was determined that the majority of the surveyed population did not know about visceral leishmaniasis (77%), did not identify it as a zoonotic disease (52%), nor did they know who the causative agent is (82%); furthermore, they were not clear about the symptoms that occur in humans, nor the treatment used to manage them. Conclusions: Although preventive campaigns have been carried out in the affected communes, the level of knowledge about the disease, the vector, the reservoir, and the specific preventive practices to counteract visceral leishmaniasis are little known in the study population, despite the fact that the identified practices and attitudes are positive.

ABSTRACT Detecting latent tuberculosis infection (LTBI) is important, especially in high-risk populations including healthcare workers (HCWs). QuantiFERON-TB Gold Plus (QFT-Plus) is a new version of the interferon-gamma release assays (IGRAs) to replace the QuantiFERON-TB Gold In-tube (QFT-GIT). However, data on the use of QFT-Plus for LTBI detection in high TB-burden countries are limited. This study was conducted in a TB-endemic setting in Thailand. HCWs were enrolled in the study and underwent both tests during the annual health screening. The testing results were compared and the concordance was determined. Of 102 HCWs, 11 (10.78%) were positive according to both tests, and 15 (14.71%) were positive according to QFT-Plus. The overall agreement between assays was 96.08%, with Cohen's kappa coefficient (k) at 0.82. All four discordant results occurred with QFT-GIT negative and QFT-Plus positive. The comparison between QFT-GIT and QFT-Plus based on each antigen tube (TB1 or TB2) exhibited similar concordance with 99.02% and 95.10% agreement, respectively. The intra-comparison between TB1 and TB2 of QFT-Plus also showed good concordance at 96.08%. Among this group of HCWs, the LTBI prevalence of any positive results in both tests was low. Overall, the study showed good agreement between QFT-Plus and QFT-GIT (k = 0.82) with a minimal difference, suggesting similar assay performance to that mainly carried out in TB-low incidence countries. The results support the use of QFT-Plus for detecting LTBI in a format similar to QFT-GIT.

ABSTRACT Background: Scorpions are a leading cause of envenomation in Brazil. The species Tityus serrulatus is associated with the most severe cases, especially in children. Despite not being endemic to the state of Santa Catarina, such occurrences have increased more than 500% in the state recently. Therefore, this study aimed to analyze the occurrence of envenomation by T. serrulatus, attended by the Center for Toxicological Information and Assistance of Santa Catarina. Methods: This was a retrospective and descriptive study of the occurrence of T. serrulatus, identified by the agency, from 2014 to 2021 in Santa Catarina, using data obtained by the BI-DATATOX system. Results: A total of 112 occurrences were classified as envenomation. Of these cases, 48.2% were recorded in the Itajaí Valley region and 33% in Greater Florianópolis. Men were involved in 59.8% of these, and the most common age group was 20-39 years (39.3%). Most envenomation occurred in urban areas (89.3%) under non-occupational circumstances (83%). Stings were more frequent on the hands (50.9%). Care was sought within 1 h after the event in 75.9% of the cases, and 94.6% were classified as mild. Conclusions: Occurrence of envenomation involving T. serrulatus in Santa Catarina increased significantly during the study period. Most cases occurred in urbanized areas, which suggests that they might have been transported from other states, and it must be considered that, in the urban environment, scorpions find a large supply of food and shelter and a reduced number of specific predators, allied to parthenogenesis.

Resumo Objetivo Traçar o perfil sociodemográfico dos agentes de combate a endemias (ACEs) dos municípios que compõem a microrregional de saúde de Itaúna, Minas Gerais; e apreender a percepção dos profissionais da vigilância entomológica sobre a doença de Chagas e serviços de saúde. Metodologia Aplicou-se um questionário semiestruturado aos ACEs e foi realizado um grupo focal com os coordenadores de endemias e digitadores. Resultados Dentre os ACEs, a maioria era do sexo feminino, entre 21 e 40 anos, com ensino médio, possuindo contrato de trabalho temporário há menos de 5 anos. Foi possível apreender: as más condições de trabalho dos ACEs, destacando-se a alta rotatividade e defasagem salarial; ausência de ações de promoção à saúde relacionadas à doença de Chagas; desarticulação entre a Atenção Primária à Saúde (APS) e Vigilância à Saúde (VS); e críticas às ações de controle da doença pós-processo de descentralização da saúde. Conclusões Há urgência na concretização da legislação inerente à natureza trabalhista e às condições de trabalho dos ACEs, bem como ao planejamento conjunto das ações de APS e VS, garantindo a atenção integral por meio de ações de promoção à saúde voltadas à população, focando especialmente a doença de Chagas, consolidando o SUS.
Abstract Objective To trace the sociodemographic profile of endemic disease combat agents (ACEs) in the municipalities that make up the health microregion of Itaúna, Minas Gerais; and apprehend the perception of entomological surveillance professionals about Chagas disease and health services. Methodology A semi-structured questionnaire was applied to the ACEs and a focus group was held with coordinators of endemic diseases and typists. Results Among the ACEs, the majority were female, between 21 and 40 years old, with high school education, with a temporary work contract for less than 5 years. It was possible to apprehend: the poor working conditions of the ACEs, highlighting the high turnover and wage gap; absence of health promotion actions related to Chagas disease; disarticulation between Primary Health Care (PHC) and Health Surveillance (HS); and criticism of disease control actions after the health decentralization process. Conclusions There is an urgent need to implement the legislation inherent to the labor nature and working conditions of the ACEs, as well as the joint planning of PHC and SV actions, guaranteeing comprehensive care through health promotion actions aimed at the population, focusing especially on Chagas disease, consolidating the SUS.

Abstract The antioxidant, photoprotective and antinociceptive Marcetia macrophylla active extract was investigated as an active ingredient in a sunscreen cream formulation. Thus, the M. macrophylla extract showed IC50 of 3.43 mg/ml of the antioxidant (DPPH scavenging test) and Sun Protection Factor of 20.25 (SPF/UV-B, at 250 µg/ml) and UV-A of 78.09% (photobleaching trans-resveratrol test). The antinociceptive activity was superior to all standards tested using the in vivo acetic acid-induced writhing test (99.14% at the dose of 200 mg/kg) and the high-performance liquid chromatography coupled with diode array detector and mass spectroscopy multi-stage (HPLC-DAD-MS/MS) enabled the structural characterization of the quercetin-3-O-hexoside, quercetin-3-O-pentoside and quercetin-3-O-desoxihexoside. The pharmaceutical formulation containing the Marcetia macrophylla crude active extract was prepared and the physicochemical tests (organoleptic characteristics, pH analysis and centrifugation), the in vitro UVB (sun protection factor, SPF) and UVA (-carotene) using the spectroscopic method were investigated. The formulation showed satisfactory results concerning the physicochemical parameters evaluated and active against the UV test. Thus, M. macrophylla showed biological activities with potential use in pharmaceutical preparations.
Resumo O extrato bruto de Marcetia macrophylla mostrou atividade antioxidante, fotoprotetora e antinociceptiva, sendo em seguida investigado como ingrediente ativo em uma formulação fotoprotetora. Assim, o extrato de M. macrophylla apresentou atividade antioxidante com IC50 de 3,43 mg/mL (teste de sequestro do DPPH) e Fator de Proteção Solar de 20,25 (FPS/UV-B, 250 µg/mL) e UV-A de 78,09% (teste de fotobranqueamento do trans-resveratrol). A atividade antinociceptiva usando o teste in vivo de contorções abdominais induzidas por ácido acético foi superior a todos os padrões testados (99,14% na dose de 200 mg/Kg). A análise por cromatografia líquida de alta eficiência acoplada a detector de fotodiodos e espectroscopia de massas multi-estágio (CLAE-DAD-EM/EM) possibilitou a caracterização dos flavonoides quercetina-3-O-hexosídeo, quercetina-3-O-pentosídeo e quercetina-3-O-desoxihexosídeo. A formulação farmacêutica contendo o extrato ativo bruto de Marcetia macrophylla foi preparada e os testes físico-químicos (características organolépticas, análise de pH e centrifugação), o UVB in vitro (fator de proteção solar, FPS) e UVA (-caroteno) foram investigados. A formulação apresentou resultados satisfatórios frente aos parâmetros físico-químicos avaliados e ativos contra UV. Assim, M. macrophylla apresentou atividades biológicas com potencial uso em preparações fitofarmacêuticas.

Abstract Dengue fever (DF) is increasingly recognized as one of the worlds major mosquito borne diseases and causes significant morbidity and mortality in tropical and subtropical countries. Dengue fever is endemic in most part of Pakistan and continues to be a public health concern. Knowledge, attitude and practices can play an important role in management of the disease. Current study was aimed to determine the level of knowledge, attitude and practices regarding dengue fever among health practitioners, to study the level of knowledge and attitude with preventive practices for dengue fever. A cross sectional study was carried out in medical practitioners of the four districts of Malakand region during October to November 2019. A pre-structured questionnaire was used to collect data from medical practitioners. Data was analyzed using Graph Pad version 5. Significant value was considered when less than 0.05 (at 95% confidence of interval). The results revealed that most of participants have seen dengue vector (62%), the media being the most quoted source of information. Nearly 81.2% participants were aware from transmission of dengue fever is by mosquito bite. Practices based upon preventive measures were found to be predominantly focused towards prevention of mosquito bites rather than elimination of breeding places. Although the knowledge regarding DF and mosquito control measure was quite high among the medical practitioners but this knowledge was not put into practice. Further studies are required to aware the people about dengue and its vector in order to get prevention and control.
Resumo A dengue (DF) é cada vez mais reconhecida como uma das principais doenças transmitidas por mosquitos do mundo e causa significativa morbidade e mortalidade em países tropicais e subtropicais. A dengue é endêmica na maior parte do Paquistão e continua a ser um problema de saúde pública. Conhecimento, atitude e práticas podem desempenhar papel importante no manejo da doença. O presente estudo teve como objetivo determinar o nível de conhecimento, atitude e práticas em relação à dengue entre os profissionais de saúde, para estudar o nível de conhecimento e atitude com as práticas preventivas da dengue. Um estudo transversal foi realizado com médicos dos quatro distritos da região de Malakand de outubro a novembro de 2019. Um questionário pré-estruturado foi usado para coletar dados de médicos. Os dados foram analisados no Graph Pad versão 5. Valor significativo foi considerado quando menor que 0,05 (com intervalo de confiança de 95%). Os resultados revelaram que a maioria dos participantes já viu o vetor da dengue (62%), sendo a mídia a fonte de informação mais citada. Quase 81,2% dos participantes sabiam que a transmissão da dengue é por picada de mosquito. Constatou-se que as práticas baseadas em medidas preventivas se concentravam predominantemente na prevenção de picadas de mosquitos, e não na eliminação de criadouros. Embora o conhecimento sobre DF e medidas de controle de mosquitos fosse bastante elevado entre os médicos, esse conhecimento não foi colocado em prática. Mais estudos são necessários para conscientizar a população sobre a dengue e seu vetor, a fim de se obter prevenção e controle.

Résumé
Over the past decade, remarkable progress has been made in prevention and control of endemic diseases in China through implementation of the 12th and the 13th Five-Year National Plans for Prevention and Control of Endemic Diseases and the Three-Year Action Plan for Special Prevention and Control of Endemic Diseases. Based on the latest monitoring data of endemic diseases and the evaluation results of the control and elimination of endemic diseases of the 13th Five-Year Plan, this paper analyzed current main problems in prevention and control of endemic diseases in China, focusing on implementation of prevention and control measures for iodine deficiency disorders, endemic fluorosis, and endemic arsenicosis, as well as the treatment and management of patients. Accordingly, corresponding countermeasures and suggestions are put forward from three aspects, including prevention and control mechanism, implementation of prevention and control measures, and scientific research, so as to provide scientific basis for the country and various regions to consolidate the achievements of prevention and control of endemic diseases and accurately implement the prevention and control measures of endemic diseases.
Résumé
@#Genitourinary tuberculosis (GUTB) represents a critical aspect of extra‑pulmonary tuberculosis (TB). While it is the second most common form of this disease, its diverse clinical presentations pose a substantial challenge. This report, titled “Varied Clinical Presentations of Genitourinary Tuberculosis: A Case Series from a Tertiary Philippine Hospital,” aims to shed light on the intricacies of GUTB diagnosis, treatment, and its broader implications. In this case series, we present five unique clinical scenarios. Cases 1, 2, and 3, having completed TB treatment, developed spontaneous genitourinary fistulae. Case 4 was initially managed as interstitial cystitis, while Case 5 underwent diverticulectomy for a urethral diverticulum. The diagnosis of GUTB as the underlying cause in these cases, despite conventional treatment, highlights the diagnostic challenges posed by this disease. All five patients, experienced irritative voiding symptoms and recurrent urinary tract infections with limited improvement following antibiotic therapy. Imaging studies consistently revealed upper urinary tract involvement. Importantly, only one case exhibited histologic evidence of granuloma suggestive of GUTB, and microbiologic confirmation of Mycobacterium tuberculosis infection was obtained in only two cases. This underscores the need for a multidimensional diagnostic approach. The findings in this case series emphasize that GUTB diagnosis, often reliant on clinical findings supported by imaging studies and suggestive cystoscopy findings, remains critical for prognosis, even in the absence of microbiologic confirmation. Beyond the individual cases, this series offers insights into the complexity of GUTB, raising questions about the overall management and implications for TB control.

ObjectiveTo analyze the monitoring data of schistosomiasis from 2004 to 2021 in Suzhou New District， Jiangsu Province， and to provide evidence for improving schistosomiasis elimination strategies. MethodsFollowing the Opinions on Prevention and Control of Schistosomiasis， Parasitic Diseases and Endemic Diseases in Suzhou and the Technical Plan for Prevention and Control of Schistosomiasis， Parasitic Diseases and Endemic Diseases in Suzhou， the monitoring of schistosomiasis in the population and snail habitats from 2004 to 2021 was conducted. The Mann-Kendall method and Joinpoint regression method were employed to analyze the trend of epidemic indicators （such as seropositive rate， prevalence of snail frames， etc.）. Time series analysis （exponential smoothing model） was conducted to predict snail occurrence. ResultsFrom 2004 to 2021， a total of 73 680 people were serologically tested for schistosomiasis， with a positive rate of 0.084%. The seropositivity rate showed statistically significant differences between different years （χ2=70.73， P<0.05）， but there was no significant trend over time. In addition， 3 053 fecal tests were conducted and no positive result was found. The snail habitats covered an area of 70.11 hm2 and showed a decreasing trend （Z=-1.97， P<0.05）. A total of 30 093 frames were surveyed， of which 19.038% contained snails. The difference in the prevalence of snail frames between different years was statistically significant （χ2=7 203.09， P<0.05）， with a decreasing trend in the prevalence of snail frames （Z=-2.05， P<0.05）. A total of 26 296 live snails were seized and density of live snails was 0.874 snails per frame， showing a decreasing trend in the density of live snails （Z=-2.35， P<0.05）. A total of 12 391 snails were dissected and no infected snail was found. The areas treated with molluscicides remained stable at 264.60 hm2. An area of 27.77 hm2 achieved the goal of snail eradication through environmental modification， with a decreasing trend （Z=-2.44， P<0.05）. It is estimated that the prevalence of snail frames and snail density will remain relatively stable from 2022 to 2026， but the snail habitat area will fluctuate significantly， showing an increasing trend. ConclusionNo indigenous cases of schistosomiasis and no infected snails are reported， indicating the successful consolidation of schistosomiasis prevention and control measures. However， the snail habitat area fluctuates greatly with an increasing trend， suggesting the need for long-term Oncomelania snail monitoring in local areas.
Résumé
This report presented the endemic status of schistosomiasis and analyzed the data collected from the national schistosomiasis prevention and control system and national schistosomiasis surveillance program in the People’s Republic of China in 2022. Among the 12 provinces (municipality and autonomous region) endemic for schistosomiasis, Shanghai Municipality, Zhejiang Province, Fujian Province, Guangdong Province and Guangxi Zhuang Autonomous Region continued to maintain the achievements of schistosomiasis elimination, and Sichuan and Jiangsu provinces maintained the criteria of transmission interruption, while Yunnan, Hubei, Anhui, Jiangxi and Hunan provinces maintained the criteria of transmission control by the end of 2022. A total of 452 counties (cites, districts) were found to be endemic for schistosomiasis in China in 2022, with 27 434 endemic villages covering 73 424 400 people at risk of infections. Among the 452 endemic counties (cities, districts), 75.89% (343/452), 23.45% (106/452) and 0.66% (3/452) achieved the criteria of elimination, transmission interruption and transmission control of schistosomiasis, respectively. In 2022, 4 317 356 individuals received serological tests for schistosomiasis, and 62 228 were sero-positive. A total of 208 646 individuals received stool examinations for schistosomiasis, with one positive and another two cases positive for urine microscopy, and these three 3 cases were imported schistosomiasis patients from Africa. There were 28 565 cases with advanced schistosomiasis documented in China by the end of 2022. Oncomelania hupensis snail survey was performed in 18 891 endemic villages in China in 2022 and O. hupensis snails were found in 6 917 villages (36.62% of all surveyed villages), with 8 villages identified with emerging snail habitats. Snail survey was performed at an area of 655 703.01 hm2 and 183 888.60 hm2 snail habitats were found, including 110.58 hm2 emerging snail habitats and 844.35 hm2 re-emerging snail habitats. There were 477 200 bovines raised in the schistosomiasis endemic areas of China in 2022, and 113 946 bovines received serological examinations for schistosomiasis, with 204 sero-positives detected. Among the 131 715 bovines received stool examinations, no positives were identified. In 2022, there were 19 726 schistosomiasis patients receiving praziquantel chemotherapy, and expanded chemotherapy was performed in 714 465 person-time for humans and 234 737 herd-time for bovines in China. In 2022, snail control with chemical treatment was performed at an area of 119 134.07 hm2, and the actual area of chemical treatment was 65 825.27 hm2, while environmental improvements were performed at an area of 1 163.96 hm2. Data from the national schistosomiasis surveillance program of China showed that the mean prevalence of Schistosoma japonicum infections was both zero in humans and bovines in 2022, and no S. japonicum infection was detected in O. hupensis snails. These data demonstrated that the endemic status of schistosomiasis continued to decline in China in 2022, with 3 confirmed schistosomiasis patients that had a foreign nationality and all imported from Africa, and the areas of snail habitats remained high. Further improvements in the construction of the schistosomaisis surveillance and forecast system, and reinforcement of O. hupensis survey and control are required to prevent the re-emerging schistosomiasis.
Résumé
Objective To analyze the epidemiological characteristics of echinococcosis cases reported in the National Notifiable Disease Report System in Henan Province from 2010 to 2011, so as to provide insights into for echinococcosis control and surveillance. Methods The data pertaining to reported echinococcosis cases in Henan Province from 2010 to 2021 were retrieved from the National Notifiable Disease Report System, and a descriptive epidemiological analysis was performed using the software SPSS 22.0. Results A total of 150 echinococcosis cases were reported in Henan Province from 2010 to 2021, including 88 confirmed cases (58.67%) and 62 clinically diagnosed cases (41.33%), 77 cases reported by Henan Province (51.33%) and 73 cases reported by other provinces (48.67%). Echinococcosis cases were reported in each month, with 8 to 21 cases reported in each month, and the number of reported echinococcosis cases appeared no remarkable temporal changes. The echinococcosis cases were reported across 18 cities of Henan Province, with the highest number of cases reported in Zhoukou (17.33%) and Nanyang cities (17.33%) and the lowest number reported in Sanmenxia City (0.67%). The reported echinococcosis cases had a male to female ratio of 1.17:1, and the cases were found at each age group, with the the highest number of cases seen at ages of 20 to 59 years (73.33%). Farmer was the predominant occupation (63.33%), followed by housekeepers and the unemployed (12.67%). Of all reported echinococcosis cases, there were 25 local cases (16.67%) and 125 imported cases (83.33%), 144 cases reported by medical institutions (96.00%) and 6 cases reported by centers for disease control and prevention (4.00%). Conclusions Although imported echinococcosis cases were the predominant source of echinococcosis cases reported in the National Notifiable Disease Report System in Henan Province from 2010 to 2021, there were still sporadic local cases, and the emergence of local sources of infection cannot be excluded. Further expanded field surveys and surveillance of echinococcosis are required.
