Factores asociados al tratamiento no exitoso para tuberculosis en pacientes previamente tratados en Cali, Colombia, en el periodo 2015-2019 / Factors associated with unsuccessful treatment outcome for tuberculosis in previously treated patients in Cali, Colombia, during the period 2015-2019

Introducción. Las tasas de éxito del tratamiento de la tuberculosis continúan siendo subóptimas. Objetivo. Identificar los factores asociados al tratamiento no exitoso para tuberculosis en pacientes con antecedentes de tratamiento para la tuberculosis. Materiales y métodos. Se realizó un estudio observacional retrospectivo, analítico, de cohorte de pacientes que reingresaron a un programa de micobacterias en Cali, Colombia. Se incluyeron mayores de 15 años con tuberculosis pulmonar entre el 2015 y el 2019 con antecedentes de tratamiento para la tuberculosis. Se excluyeron los pacientes con tuberculosis resistente. Resultados. Ingresaron 605 pacientes con antecedentes de tratamiento, 60 % por tratamiento inconcluso y 40 % por recaída. En comparación con los pacientes que reingresaron por recaída (ORa= 2,34; IC=1,62-3,38), las variables que explicaron de manera independiente el no tener éxito con el tratamiento para la tuberculosis al egreso fueron: estar en situación de calle (ORa = 2,45; IC = 1,54-3,89), ser farmacodependiente (ORa = 1,95; IC=1,24-3,05), tener coinfección tuberculosis/VIH (ORa = 1,69; IC =1,00- 2,86) o diabetes (ORa =1,89; IC=1,29-2,77), y el incumplimiento de un tratamiento previo por pérdida de seguimiento, abandono u otras causas. Las variables programáticas que favorecieron el éxito del tratamiento fueron la asesoría de la prueba voluntaria de VIH (p < 0,001) y la realización de la prueba de VIH (p < 0,001). Conclusión. Estar en situación de calle, ser farmacodependiente, tener coinfección de tuberculosis y VIH, o diabetes, así como el incumplimiento del tratamiento previo por pérdida del seguimiento, abandono o fracaso del mismo, dificultaron el éxito del tratamiento antituberculoso. En la primera atención al reingreso de los pacientes con tuberculosis se deben identificar y abordar estas características.

Introduction. The success rates in the treatment of tuberculosis are suboptimal. Objective. To identify associated factors with the lack of success of antituberculosis treatment in patients with a tuberculosis treatment history. Materials and methods. We performed a retrospective, analytical, observational, and cohort study of patients reentering the Mycobacterium program in Cali, Colombia. We included patients over 15 years old with pulmonary tuberculosis between 2015 and 2019 and a history of tuberculosis treatment. Patients with drug-resistant tuberculosis were excluded. Results. A total of 605 patients with a treatment history were included, 60% due to unfinished treatment and 40% due to relapse. Compared to patients reentering due to relapse (ORa=2.34, CI=1.62-3.38), the independent variables associated with treatment failure at discharge were homelessness (ORa=2.45, CI=1.54-3.89), substance dependence (ORa=1.95, CI=1.24-3.05), tuberculosis/HIV coinfection (ORa=1.69, CI=1.00-2.86), diabetes (ORa=1.89, CI=1.29-2.77), and unfinished previous tuberculosis treatment due to follow-up loss, abandonment, or other causes. Programmatic variables favoring treatment success were voluntary HIV testing counseling (p<0.001) and HIV testing (p<0.001). Conclusion. Homelessness, substance dependence, tuberculosis/HIV coinfection, diabetes, and incomplete previous treatment due to loss to follow-up, abandonment, or treatment failure hindered the success of antituberculosis. These characteristics should be identified and addressed during the initial care of patients reentering treatment for tuberculosis.

Social determinants and sexual risk behaviors within Immunodeficiency Virus cases in Solidaridad, Quintana Roo, México / Determinantes sociales y conductas sexuales de riesgo en casos de Virus de la Inmunodeficiencia en Solidaridad, Quintana Roo, México

Abstract Objective: To determine the prevalence of HIV in individuals by analyzing the influence of social determinants and sexual risk behaviors, in order to estimate the crude and adjusted risks of being HIV positive in the municipality of Solidaridad, state of Quintana Roo, Mexico. Method and Materials: A cross-sectional study was conducted in the municipality of Solidaridad, Quintana Roo, Mexico. Third and fourth generation HIV rapid tests were performed. Descriptive statistics, measures of association (OR and 95 % CI) and p value were calculated for each stratum. Logistic regression models were performed to determine the risk factors associated with being HIV positive in the tests. Results: The sample consisted of 4,800 people, of whom 3,030 were men (63.12%); the mean age was 32.6 years (SD 14.96). The variables included in the multivariate model for being HIV positive are: men who have sex with men with OR=61.20, age 30-39 years OR=1.72, having anal sex OR=2.21, and as a protective factor having health service OR =0.42. Conclusions: This study confirms already known social determinants such as being male and being in economically active age and sexual practices such as: having anal sex and men with men. Being entitled to health services was shown to be the only protective factor.

The first-born were protected from self-medication PRa=0,86 (95% CI: 0,76-0,97). Parents who were between 20 and 29 years of age obtained PRa=1,04 (95% CI: 0,96-1,13), children under 7 years old, PRa=0,99 (95% ci: 0,91-1,07) and parents of family that had 1 child PRa=1,04 (95% CI:0,90-1,20). Conclusions: the educational level and the order number of the child, such as being the first-born, had a significant association with self-medication in children.

Malformações congênitas em uma cidade da região metropolitana de Curitiba-PR / Congenital malformations in a city of the metropolitan region of Curitiba-PR / Malformaciones congénitas en una ciudad de la región metropolitana de Curitiba-PR

Malformações congênitas (MC) são alterações estruturais/funcionais que ocorrem no feto trazendo impacto socioeconômico e emocional. Estudo retrospectivo, documental, de abordagem quantitativa, com o objetivo de identificar a relação dos fatores de risco e perfil epidemiológico materno com a ocorrência de MC. Baseou-se na análise de 37 prontuários de gestantes em município da região metropolitana de Curitiba-PR, entre 2019 e 2021. Os achados revelaram um perfil: gestantes entre 18 e 36 anos, multíparas, obesas, com comorbidades, sem avaliação pré-concepcional. Os sistemas orgânicos mais acometidos foram o cardiovascular, o nervoso ou múltiplos sistemas. Identificou-se risco aumentado de malformações fetais em mulheres maiores de 25 anos, obesas, que utilizaram álcool ou tabaco. Embora uma causa única das MC nesse período e local não tenha sido identificada, estabeleceu-se associação entre fatores epidemiológicos maternos e características das malformações fetais, evidenciando necessidade de educação em saúde pré-concepcional

Congenital malformations (CM) are structural/functional alterations that occur in the fetus, leading to a socio-economic and emotional impact. This is a retrospective, documentary study with a quantitative approach aiming at identifying the relationship of risk factors and maternal epidemiological profile with the occurrence of CM. It was based on the analysis of 37 medical charts of pregnant women in a municipality in the metropolitan region of Curitiba-PR, between 2019 and 2021. The data revealed a profile: pregnant, multiparous, obese women between 18 and 36 years old, with comorbidities, with no preconception evaluation. The most affected organic systems were the cardiovascular and the nervous systems or multiple systems. An increased risk of fetal malformations was observed in obese women over 25 years old, who used alcohol or tobacco. Although a single cause of CM in that period and place has not been identified, an association was established between maternal epidemiological factors and characteristics of fetal malformations, highlighting the need for preconception health education.

Las malformaciones congénitas (MC) son alteraciones funcionales que ocurren en el feto, llevando consigo un impacto socioeconómico y emocional. Estudio retrospectivo, documental, con abordaje cuantitativo, con el objetivo de identificar la relación entre los factores de riesgo y el perfil epidemiológico materno con la ocurrencia de MC. Se basó en el análisis de 37 prontuarios de embarazadas del municipio de la región metropolitana de Curitiba-PR, entre 2019 y 2021. Los hallazgos revelaron un perfil: embarazadas entre 18 y 36 años, multíparas, obesas, con comorbilidades, sin evaluación preconcepcional. Los sistemas orgánicos más afectados fueron los sistemas cardiovascular, nervioso o múltiple. Se identificó un mayor riesgo de malformaciones fetales en mujeres mayores de 25 años, obesas, consumidoras de alcohol o tabaco. Aunque no se ha identificado una causa única de MC en ese período y lugar, se estableció una asociación entre los factores epidemiológicos maternos y las características de las malformaciones fetales, destacando la necesidad de la educación sanitaria previa a la concepción

Analysis of verification results of protective effects of hearing protectors in different industries / 中华劳动卫生职业病杂志

Objective: To get insight into the current practice of noise reduction effect of workers as they wore hearing protectors in different domestic enterprises and the possible affected factors. Methods: From October 2020 to April 2021, using a random sampling method, 1197 workers exposed to noise in petrochemical factories, textile factories, and parts manufacturing factories were selected as the study subjects. The noise reduction effect of hearing protectors worn by workers in daily use was tested using a hearing protector suitability testing system. The personal sound attenuation level (PAR) was compared among workers in three enterprises, Targeted intervention and repetitive testing were conducted for workers who did not meet the noise reduction effect required by the enterprise, and the changes in PAR of workers before and after the intervention were compared. The comparison of baseline PARs between two or more groups was performed using the Mann Whitney test, the comparison of baseline PARs with post intervention PARs was performed using the Wilcoxon signed rank sum test, and the comparison of qualitative data between two or more groups was performed using the Chi square test. Results: The median baseline PAR for all workers was 15 dB. Men, age<30 years old, education level at or above college level, working experience of 5 to 15 years, and those who used hearing protectors for 5 to 15 years had higher PARs, with statistically significant differences (P<0.05). The median difference in baseline PAR among workers from three enterprises was statistically significant (H=175.06, P<0.01). The median PAR of subjects who did not pass the baseline increased from 3 dB to 21 dB after intervention (Z=-27.92, P<0.01) . Conclusion: Some workers wearing hearing protectors do not meet the required PAR, and low PARs may be related to incorrect wearing methods and incorrect selection of hearing protectors. As a tool for testing, training, and assisting in selection, the hearing protector suitability testing system is of great significance for worker hearing protection.

Prevalence of hearing loss among community-dwelling older people in China in 2020 / 中华老年医学杂志

Objective:To investigate the prevalence of hearing loss among community-dwelling older people aged 60 and over, and also to compare the discrepancies between self-reported hearing loss and hearing loss diagnosed via audiometry.Methods:Subjects were from the Prevention and Intervention on Neurodegenerative Disease for the Elderly in China(PINDEC)project.By using the stratified multi-stage cluster random sampling method, a total of 10 347 residents aged 60 years and over were selected from 12 counties and districts in Liaoning, Henan and Guangdong Provinces and hearing function assessment was performed in 2020 through otoscopy, pure-tone audiometry and questionnaires.Hearing loss(HL)was defined by the World Health Organization criteria.Self-reported hearing loss was assessed by asking participants whether they had difficulty in hearing.The χ2 and Cochran-Armitage trend tests were used to analyze the differences in HL between different groups.The multivariate Logistic regression model was applied to assess factors influencing HL. Results:In 2020, the prevalence of HL among the elderly aged 60 and older in Liaoning, Henan and Guangdong Provinces was 69.8%(95% CI: 68.9%-70.7%). The prevalence of HL in men was higher than that in women, and increased gradually with age.The prevalence of mild HL was 47.2%, and the prevalence of moderate, severe and profound HL were 18.0%, 3.6% and 0.9%, respectively.Multivariate Logistic regression analysis showed that factors positively correlated with HL were aging, male sex, living in rural areas and working in manual labor.Education level was negatively correlated with HL.Of the 7223 participants who were found to have HL, 5106(70.7%)self-reported having good hearing.Those of a younger age, with a higher educational achievement, having a spouse, or with mild HL were more likely to report having good hearing(all P<0.05). Conclusions:Hearing loss is quite prevalent among community-dwelling older people, and there is a large discrepancy in prevalence between self-reported HL and HL diagnosed via audiometry.Screening and comprehensive intervention for hearing loss for the elderly should be strengthened.

Introduction: Type 2 Diabetes Mellitus (T2DM) is a disease that poses a challenge to public health due to its growth trend and impact, especially in developing countries. This study aimed to determine the factors associated with not being screened for T2DM according to the 2020 Demographic and Family Health Survey (ENDES-2020). Materials and Methods: Secondary, cross-sectional, analytical study using the ENDES-2020 data. Results: The variables that showed a statistically significant association for T2DM screening were the following: male sex (PR=1.06, 95% CI: 1.02­1.10; p<0.001), ages between 30 and 59 years (0.92, 95% CI: 0.89­0.95; p<0.001) and 60 years and older (PR=0.72, 95% CI: 0.65­0.79; p<0.001), primary education (PR=0.94, 95% CI: 0.92­0.99; p<0.020), secondary education (PR=0.93, 95% CI: 0.88­0.97; p=0.008) higher education (PR=0.86, 95% CI: 0.85­0.94; p<0.001), poor (PR=0.96, 95% CI: 0.92­0.99; p=0.016), middle income (PR=0.93, 95% CI: 0.88­0.96; p=0.001), rich (PR=0.89, 95% CI: 0.84­0.94; p<0.001), very rich (PR=0.81, 95% CI: 0.75­0.86; p<0.001), and hypertension (PR=0.91, 95% CI: 0.867­0.969; p=0.002). Discussion: Being male was the only factor associated with not being screened for T2DM, whereas belonging to an older age group, having arterial hypertension, and having higher education and socioeconomic levels increased the possibility of being screened. Conclusion: It is essential to strengthening screening strategies at the primary level of care by implementing preventive measures.

Esclerose lateral amiotrófica em Belo Horizonte, Brasil entre 2010 e 2020: um estudo clínico epidemiológico / Amyotrophic lateral sclerosis in Belo Horizont, Brazil between 2010 and 2020: a clinical epidemiological study

Objetivo: Descrever o perfil clínico de indivíduos com Esclerose Lateral Amiotrófica (ELA) de um hospital de referência na cidade de Belo Horizonte, Brasil. Métodos: Trata-se de um estudo transversal retrospectivo com coleta de dados de prontuários eletrônicos de indivíduos com diagnóstico definido de ELA entre 2010 e 2020, no setor de referência em Distrofias Musculares de um hospital de uma capital brasileira. Resultados: Foram incluídos 103 indivíduos com ELA, com idade média de 60±12 anos, idade média de diagnóstico de 56±12 anos e tempo médio de evolução da doença de 3±3 anos. Além disso, 70% eram do sexo masculino, 88% com ELA esporádica, com envolvimento bulbar semelhante entre leve (32%), moderado (27%) e grave (28%), e com maior taxa de diagnóstico de 50 a 70 anos de idade. Conclusão: Os dados epidemiológicos deste estudo são muito semelhantes aos da literatura. No entanto, a heterogeneidade da doença, a complexidade do diagnóstico e a diversidade de formas que cada estudo traz para a doença, e principalmente a rápida progressão, dificultam a discussão de um quadro mais extenso. Traçar esse perfil é importante para uma clínica mais focada e um manejo mais adequado, e para isso são necessários mais estudos.

Objective: To describe the clinical profile of individuals with Amyotrophic Lateral Sclerosis (ALS) from a reference hospital in the city of Belo Horizonte, Brazil. Method: This is a retrospective cross-sectional study with data collection from electronic medical records of individuals with a defined diagnosis of ALS between 2010 and 2020, in the Muscular Dystrophies reference sector of a hospital in a Brazilian capital. Results: A total of 103 individuals with ALS were included, with a mean age of 60±12 years, mean diagnostic age 56±12 years, and mean time of disease progression of 3±3 years. Furthermore, 70% were male, 88% with sporadic ALS, with a similar bulbar involvement between mild (32%), moderate (27%) and severe (28%), and with a higher rate of diagnosis from 50 to 70 years of age. Conclusion: The epidemiological data from this study are very similar to those in the literature. However, the heterogeneity of the disease, the complexity of the diagnosis and the diversity of forms that each study brings to the disease, and especially the rapid progression, make a more extensive picture difficult to be discussed. Tracing this profile is important for a more focused clinic and a more adequate management, and for that, further studies are needed.

Factores asociados al fenotipo delgado metabólicamente obeso en pobladores peruanos

Introducción: Los pacientes con el fenotipo delgado metabólicamente obeso (DMO) pueden presentar el mismo riesgo que los obesos clásicos para desarrollar enfermedades crónicas a largo plazo. No obstante, la prevalencia y los factores que se encuentran asociados este varía de acuerdo con la población estudiada. Objetivo: determinar la prevalencia y los factores se encuentran asociados al fenotipo DMO en el Perú. Métodos: Estudio analítico de corte transversal. Análisis secundario de la base de datos del estudio PERU MIGRANT. Los factores asociados que se consideraron fueron: edad (30-44 años, de 45-59 años, y 60 a más años), sexo, estado socioeconómico, nivel de educación, migración, tabaquismo, consumo de alcohol y nivel actividad física. Resultados: La prevalencia del fenotipo DMO fue de 32,23% (IC95% 27,61-37,10). En el análisis multivariable, el sexo masculino mostró 39% menor probabilidad de presentar el fenotipo DMO (PRa: 0,610; IC95% 0,428-0,869; p=0,006), en comparación con el sexo femenino. Mientras que, pertenecer a los grupos de edad entre 45-59 años y de 60 años a más presentó 110,5% (PRa: 2,105; IC95% 1,484-2,988; p<0,001) y 97,6% (PRa: 1,976; IC95% 1,270-3,075; p=0,003), respectivamente, mayor probabilidad de presentar DMO, en comparación con el grupo de 29-44 años. Conclusiones: El pertenecer al sexo femenino y a los grupos de edad de 45 a 59 y 60 años a más, aumentaron la probabilidad de presentar el fenotipo DMO. Se recomienda la realización de futuros estudios con prospectivos y con un tamaño de muestra mayor para confirmar dichos hallazgos, así como la inclusión de nuevas variables.

Introduction: Patients with the lean metabolically obese (BMD) phenotype may present the same risk as the classic obese for developing long-term chronic diseases. However, the prevalence and the factors that are associated with it vary according to the population studied. Objective: to determine the prevalence and the factors associated with the BMD phenotype in Peru. Methods: Cross-sectional analytical study. Secondary analysis of the PERU MIGRANT study database. The associated factors that were considered were: age (30-44 years, 45-59 years, and 60 years and over), sex, socioeconomic status, level of education, migration, smoking, alcohol consumption and level of physical activity. Results: The prevalence of the BMD phenotype was 32.23% (95% CI 27.61-37.10). In the multivariate analysis, the male sex showed a 39% lower probability of presenting the BMD phenotype (PRa: 0.610; 95% CI 0.428-0.869; p=0.006), compared to the female sex. While belonging to the age groups between 45-59 years and 60 years and over presented 110.5% (PRa: 2.105; 95% CI 1.484-2.988; p<0.001) and 97.6% (PRa: 1.976; CI95% 1.270-3.075; p=0.003), respectively, greater probability of presenting BMD, compared to the group of 29-44 years. Conclusions: Belonging to the female sex and to the age groups of 45 to 59 and 60 years or more, increased the probability of presenting the BMD phenotype. Future prospective studies with a larger sample size are recommended to confirm these findings, as well as the inclusion of new variables.

Marcadores humorales y su relación con variables epidemiológicas en pacientes trasplantados renales / Humoral markers and their relationship with epidemiological variables in kidney transplant patients

RESUMEN Introducción: El trasplante renal es la mejor opción disponible para el tratamiento de la insuficiencia renal crónica terminal. La determinación de marcadores humorales permite detectar y seguir la evolución del paciente trasplantado renal y la disfunción del injerto, así como sus diversas complicaciones. Objetivos: Relacionar el funcionamiento del trasplante renal realizado a pacientes con un grupo de marcadores humorales. Métodos: Se realizó una investigación descriptiva y de corte transversal en 85 pacientes trasplantados renales, previo consentimiento informado, los cuales constituían la totalidad de los pacientes del Servicio de trasplante renal, en el Hospital Universitario Clínico-Quirúrgico «Arnaldo Milián Castro¼, Santa Clara, Villa Clara, desde enero de 2015 a diciembre de 2017. Resultados: Predominaron pacientes del sexo masculino, de 40-59 años de edad. La principal enfermedad asociada fue la hipertensión arterial. Del total de trasplantados estaban con funcionabilidad 62 pacientes (72,94 %) y en ellos, fue significativo el aumento de los valores de hematocrito y albúmina, así como el valor medio de la creatinina sérica, ligeramente superior a los valores de referencia. Conclusiones: El rango de edad más frecuente fue de 40-59 años. Prevaleció el sexo masculino asociado con la hipertensión arterial. Predominó la funcionabilidad de los trasplantes realizados precozmente, con menor tiempo en diálisis. En los marcadores humorales la creatinina presentó una asociación significativa. Por otra parte, el hematocrito nunca se normalizó en los no funcionales. El conteo de Addis fue el examen que más modificación precoz sufrió ante cualquier alteración en la función renal.

ABSTRACT Introduction: renal transplantation is the best available option for the treatment of terminal chronic renal failure. The determination of humoral markers makes it possible to detect and follow the evolution of kidney transplant patients and graft dysfunction, as well as its various complications. Objectives: to relate the performance of kidney transplants performed in patients with a group of humoral markers. Methods: a descriptive and cross-sectional research was carried out in 85 kidney transplant patients, with prior informed consent, which constituted all the patients of the Kidney Transplant service from "Arnaldo Milián Castro" Clinical and Surgical University Hospital, Santa Clara, Villa Clara, between January 2015 and December 2017. Results: male patients aged 40-59 years old predominated. The main associated disease was arterial hypertension. A number of 62 patients from the total number of transplant recipients (72.94%) were functional and the increase in hematocrit and albumin values ​​was significant in them, as well as the mean value of serum creatinine was slightly higher than the reference values. Conclusions: the most frequent age range was 40-59 years. The male gender associated with arterial hypertension prevailed. The functionality of transplants performed early, with less time on dialysis, prevailed. Creatinine had a significant association in the humoral markers. On the other hand, the hematocrit never normalized in non-functional patients. The Addis count was the test that underwent the earliest changes in the event of any alteration in renal function.

Determinantes de letalidad por la COVID-19 en trabajadores de salud en la primera y segunda olas en Perú / Determinants of COVID-19 fatality among healthcare workers during the first and second waves in Peru

RESUMEN Introducción: Los trabajadores de salud presentan alto riesgo de la COVID-19, hecho especialmente importante en el Perú que tiene una de los mayores índices de letalidad por esta pandemia. Objetivo: Identificar y comparar los determinantes de letalidad por la COVID-19 en trabajadores de salud del Perú, entre la primera y segunda olas. Material y Métodos: Análisis secundario de datos de la Sala situacional de trabajadores del sector salud de COVID-19, que incluyó 95 966 casos confirmados de la COVID-19 hasta el 21 de octubre de 2021. Se calculó el índice de letalidad, así como los odds ratio -y sus intervalos de confianza a 95 %- crudo y ajustado mediante regresión logística binaria. Resultados: 65,5 % fueron mujeres, de 41,2 (D.E.=11,1) años en promedio. El índice de letalidad fue mayor durante la segunda ola (2,1 % [IC95%=2,0-2,2] vs 2,6 % [IC95 %=2,5-2,8]). El sexo masculino (3,49 [IC95 %=3,09-3,95] en la primera ola y 2,65 [IC95 %=2,32-3,02] en la segunda ola), la edad ≥40 años (9,97 [IC95 %=8,19-12,13] en la primera ola y 10,77 [IC95 %=8,56-13,54] en la segunda ola), así como ser profesional de salud (1,14 [IC95 %=1,01-1,28] en la primera ola y 1,59 [IC95 %=1,39-1,82] en la segunda ola) determinaron la letalidad por la COVID-19 en ambas olas. Conclusiones: La letalidad fue mayor en la segunda ola y se asoció a determinantes individuales, geográficos y ocupacionales de los trabajadores de salud peruanos.

ABSTRACT Introduction: Healthcare workers are at high risk of COVID-19, a fact that is especially important in Peru which has one of the highest COVID-19 case fatality rates. Objective: To identify and compare the determinants of COVID-19 case fatality among healthcare workers in Peru between the first and second waves of the pandemic. Material and Methods: Secondary analysis of data from the COVID-19 Health Sector Workers Situation Room which included 95,966 confirmed cases of COVID-19 until October 21, 2021. Case fatality rate was calculated; crude and adjusted odds ratios with 95 % confidence intervals were obtained by applying binary logistic regression.

La tuberculosis continúa siendo un problema de salud pública. Al respecto, se realizó un estudio no experimental de corte transversal, con el objetivo de caracterizar clínica y epidemiológica-mente el estado de la TB resistente a medicamentos de primera línea en la ciudad de Durán, desde enero 2015 hasta diciembre 2019. Los datos incluidos en los documentos de la matriz del programa de tuberculosis resistente. De 1111 casos nuevos de tuberculosis reportados en el cantón Durán durante el período estudiado, 45 de estos presentaron resistencia a medicamentos de primera línea. El 88,89% tuvo resistencia a rifampicina, el 33,33% de los pacientes se dispen-sarizaron en 2019. Los valores de chi cuadrado de Pearson no mostraron asociación estadística-mente significativa entre las variables investigadas (p>0,05). Entre los involucrados predominó el grupo de edades de 20 a 39 años, el sexo masculino, la tuberculosis pulmonar, infectados con VIH/sida, resistencia clasificada como primaria, los que abandonaron el seguimiento al trata-miento y la no manifestación de reacciones adversas a los medicamentos. No se observó mortali-dad entre los casos nuevos, predominando entre aquellos con recaída, el género masculino y los que tuvieron tuberculosis extrapulmonar.

Tuberculosis is a disease that continues to be a public health problem. In this regard, a non-expe-rimental cross-sectional study was carried out to characterize clinically and epidemiologically the status of TB resistant to first-line drugs in the city of Durán, from January 2015 to December 2019. The data included in the resistant tuberculosis program matrix documents. 1111 new cases of tuberculosis were reported in the Duran canton during the study period, 45 of these ones presented resistance to first-line drugs. 88.89% had rifampicin resistance, 33.33% of the patients were dispensed in 2019. Pearson's chi-square values did not show a statistically significant asso-ciation between the investigated variables (p> 0.05). Among the study population, it was predo-minated the age group between 20 and 39, male sex, pulmonary tuberculosis, infected with HIV / AIDS, resistance classified as primary, those who abandoned the follow-up to treatment and the non-manifestation of adverse drug reactions. No mortality was observed among new cases, predominantly among those ones with relapse, the male gender and those ones who had extra-pulmonary tuberculosis

Prática da episiotomia: fatores maternos e neonatais relacionados / Practice of episiotomy: maternal and neonatal related factors

Objetivo: analisar a incidência da episiotomia e os fatores maternos e neonatais relacionados. Método: estudo transversal, retrospectivo, que analisou 11.809 prontuários de mulheres que evoluíram ao parto vaginal. Realizou-se o teste qui-quadrado para identificar os fatores relacionados (p<0,05). Resultados: a incidência da episiotomia foi 59,4%. Entre as mulheres que não sofreram episiotomia, 27,0% permaneceram com períneo íntegro e 13,5% tiveram laceração espontânea. Fatores maternos relacionados foram idade inferior a 19 anos, acompanhamento pré-natal adequado, primiparidade, dinâmica uterina presente, dilatação cervical entre 1 e 3cm, bolsa amniótica rota e trabalho de parto prolongado. Os fatores neonatais foram bebês a termo, peso ao nascer ≥2500g, Apgar ≥ 7, apresentação cefálica, intercorrências com o bebê e encaminhamento ao alojamento conjunto. Conclusão: a prática da episiotomia foi elevada, a qual deve ser desencorajada, com respeito a fisiologia do nascimento e a individualidade das mulheres, para o fortalecimento dos cuidados maternos.

Objective: to analyze the incidence of episiotomy and maternal and neonatal related factors. Method: cross-sectional, retrospective study in which 11,809 medical records of women who underwent vaginal delivery were analyzed. The chi-square test was performed to identify related factors (p<0.05). Results: the incidence of episiotomy was 59.4%. Among women who did not undergo episiotomy, 27.0% had intact perineum and 13.5% had spontaneous laceration. Maternal related factors were age less than 19 years, appropriate antenatal care, primiparity, presence of uterine dynamics, cervical dilation between 1 and 3 cm, ruptured amniotic sac, and prolonged labor. Neonatal factors were full-term babies, birth weight ≥2,500g, Apgar ≥7, cephalic presentation, complications with the baby and referral to rooming-in. Conclusion: the practice of episiotomy was high and should be discouraged. Respect for the physiology of birth and the individuality of women is necessary to strengthen maternal care.

Related factors of overweight and obesity in children aged 6-12 years in Yiwu of Zhejiang province / 中国基层医药

Objective:To investigate prevalence and related factors of overweight and obesity in children aged 6-12 years in Yiwu of Zhejiang Province.Methods:The stratified sampling method was used to perform physical examination and questionnaire survey among 500 children aged 6-12 years from five schools in Yiwu (166 from city-level schools, 168 from district-level schools, and 166 from village-level schools). The number of children at each year of 6-12 years was 54 (10.8%), 66 (13.2%), 70 (14.0%), 69 (13.8%), 83 (16.6%), 79 (15.8%) and 79 (15.9%). The factors that affect the prevalence of overweight and obesity were analyzed.Results:Among 500 school-age children, the detection rates of overweight and obesity were 12.8% (64/500) and 11.6% (58/500), respectively. There were significant differences in the detection rates of overweight and obesity between male and female children (16.1%/9.0%, 15.4%/7.3%), among children whose fathers received different levels of education (primary school and below/junior high school/senior high school and above) (25.0%/13.1%/9.2%, 22.9%/11.2%/9.2%), among children whose mothers received different levels of education (primary school and below/junior high school/senior high school and above) (23.5%/12.9%/10.1%, 19.6%/13.3%/7.7%), among children living in cities versus villages (18.6%/8.8%, 16.7%/8.1%), among children performing exercise for different lengths of time (< 0.5 hours/0.5-1.0 hours/> 1.0-2.0 hours/> 2.0 hours) (21.2%/14.9%/13.1%/3.6%, 19.2%/13.1%/11.9%/3.6%), among children with different sleep time (< 8 hours/8-10 hours/>10 hours) (16.8%/14.2%/6.3%, 15.9%/12.7%/5.6%), among children taking dessert at different frequencies (< 3 days per week/3-5 days per week/> 5 days per week) (5.6%/10.3%/23.4%, 4.9%/9.4%/21.4%), among children taking sugary or carbonated drinks at different frequencies (< 3 days per week/3-5 days per week/> 5 days per week) (6.5%/11.2%/17.1%, 6.5%/9.4%/16.1%), and among children who took extra meals before bed (< 3 days per week /3-5 days per week /> 5 days per week) (15.8%/9.4%/20.3%, 14.3%/8.5%/19.0%) (overweight: χ2 = 5.61, 8.41, 6.74, 10.48, 17.45, 6.74, 22.43; obesity: χ2 = 7.88, 6.28, 6.58, 8.63, 14.76, 6.74, 20.69, all P < 0.05). Multivariate logistic regression analysis showed that boys, unbalanced diet and extra meals before bed are independent risk factors for overweight and obesity in school-age children (all P < 0.05). Sleep time, exercise time and mother's education were protective factors of overweight and obesity (all P < 0.05). Conclusion:The incidences of overweight and obesity among school-age children aged 6-12 years in Yiwu of Zhejiang province are high, and sex, mother's education level, diet, exercise and sleep are the main influential factors of overweight and obesity.

ELSA-Brasil: a 4-year incidence of hearing loss in adults with and without hypertension

ABSTRACT OBJECTIVE To compare the incidence of hearing loss among adults stratified by the occurrence of hypertension, and to investigate the association between hypertension and hearing loss. METHODS Longitudinal observational study, part of the Estudo Longitudinal da Saúde do Adulto (ELSA-Brasil, Longitudinal Study on Adult's Health). Data from the first and second waves were analyzed, including information from audiological assessment and general health of the subjects. As outcome, we considered the presence of hearing loss (hearing thresholds above 25 dBHL at frequencies from 500 Hz to 8 kHz) and, as exposure variable, hypertension (report of medical diagnosis of hypertension; and/or use of drugs to treat hypertension; and/or pressure systolic blood pressure ≥ 140 mmHg; or diastolic blood pressure ≥ 90 mmHg). As covariables for adjustment were considered: sex, age, education, race / ethnicity, income, smoking, diabetes, and occupational exposure to noise. Poisson regression analysis was conducted, estimating the crude and adjusted relative risks, with 95% confidence intervals, in order to assess the factors associated with hearing loss. RESULTS In crude analyses, the incidence of hearing loss was higher for subjects with hypertension (9.7% versus 5.4%). The crude relative risks for hearing loss was almost double (1.93; 95%CI: 1.10-3.39) for subjects with hypertension in the right ear. In the adjusted analyses, the relative risks was not significant for the hypertension variable (1.42; 95%CI: 0.75-2.67). Being 60 years or older (RR: 5.41; 95%CI: 2.79-10.50) showed a statistically significant association with hearing loss, indicating that older adults have higher relative risks for hearing loss. CONCLUSION In the adjusted analyses controlled for multiple risk factors there was no association between hypertension and hearing loss. The dichotomous variable age (being 60 years or older), on the other hand, has shown a significant association with hearing loss.

Primary Health Care during the COVID-19 pandemic in Fortaleza, Brazil: associated factors and pattern of use by mothers and children up to 18 months of age / Atenção Primária à Saúde durante a pandemia de COVID-19 em Fortaleza, Brasil: fatores associados e padrão de uso por mães e crianças de até 18 meses de idade

ABSTRACT Objective: To analyze the delay or failure to seek primary health care by the mother-child dyads during the COVID-19 pandemic, a practice that has a high potential to increase maternal and child morbidity and mortality. Methods: Data from three survey rounds of the Iracema-COVID cohort study, collected 6, 12, and 18 months after birth, showed the patterns of postpartum attendance to primary health care consultation of the mother-child dyad. Crude and adjusted multinomial logistic regressions with robust variance were used to assess factors associated with nonattendance. Results: Among the 314 cohort mothers, 25% did not attend any primary health care consultation during the 18-months postpartum, while 30% of the mothers did all three. Regarding the child, 75% had regular primary health care consultations in all three survey rounds, while 4% did not attend any in their first 18 months of life. By the end of the first COVID-19 wave, the proportion of mother and child who attended the consultations had fallen by 23 and 18%, respectively. The main factors associated with nonattendance were mothers aged below 25 years, and mothers with more than one child. Conclusion: An important delay or nonattendance to primary health care consultation by the mother-child dyad was observed during the COVID-19 pandemic. Such practice, with a high potential to increase maternal and child morbidity and mortality, was particularly frequent among younger mothers and those with more than one child.

RESUMO Objetivo: Analisar o retardo ou a não procura por atenção primária à saúde por parte do bionômio mãe-filho durante a pandemia de COVID-19, uma prática que apresenta elevado potencial de aumentar a morbimortalidade materno-infantil. Métodos: Dados de três levantamentos do estudo longitudinal Iracema-COVID, realizados aos seis, 12 e 18 meses após o parto, identificaram padrões de procura por consultas na Atenção Primária à Saúde (APS) por parte do binômio mãe-filho. A regressão multinomial bruta e adjustada com variância robusta foi utilizada para avaliar os fatores associados com a não procura. Resultados: Entre as 314 mães da coorte, 25% não realizaram nenhuma consulta na APS durante o período de 18 meses pós-parto, enquanto 30% das mães o fizeram nos três contatos do seguimento. Com relação à consulta da criança, 75% realizaram consultas de APS nos três momentos, ao passo que 4% não realizaram nenhuma consulta em seus primeiros 18 meses de vida. Ao fim da primeira onda de COVID-19, a proporção de consultas na APS de mães e crianças caiu 23 e 18%, respectivamente. Os principais fatores associados à não procura por APS foram mães com idade abaixo de 25 anos e mães com mais de um filho. Conclusão: Houve importante retardo ou não procura por APS pelo bionômio mãe-filho durante a pandemia de COVID-19. Essa prática, com elevado potencial de aumentar a morbimortalidade materno-infantil, foi mais frequente entre mães mais jovens e com mais de um filho.

Top 100 most-cited articles on intraoral squamous cell carcinoma and its risk factors: a bibliometric study

Abstract: This study aimed to analyze the 100 most-cited articles on intraoral squamous cell carcinoma and its risk factors. A literature search was conducted on November 12, 2020 using the Web of Science database. Bibliometric data were collected after study selection. Bibliometric maps were generated using VOSviewer software. Articles were ranked based on the number of citations, ranging from 108 to 1513 per study. Eleven studies presented at least 400 citations. Articles were published between 1950 and 2017 and were mostly case-control studies (n = 39) and narrative reviews (n = 29). The author and institution in most articles were S. Franceschi (n = 10) and the International Agency for Research on Cancer (n = 10), respectively. The most prominent countries were the United States (n = 35), the United Kingdom (n = 16), and France (n = 9). Among the 100 most-cited articles, only one article was from Brazil, and the authors were affiliated with the Ludwig Institute for Cancer Research. Bibliometric maps showed strong associations between the terms alcohol, smoked/smokeless tobacco, and human papillomavirus. Emerging terms, such as areca nut and betel quid, were cited in recent articles. In conclusion, alcohol, tobacco, and human papillomavirus were the most prominent risk factors. Case-control design was the most common study design, and the majority of studies were conducted in the United States by the International Agency for Research on Cancer.

Determinants of exclusive breastfeeding among Haitian children under 6 months of age / Los determinantes de la lactancia materna exclusiva en menores de 6 meses de edad en Haití / Determinantes do aleitamento materno exclusivo entre crianças haitianas com menos de 6 meses de idade

ABSTRACT Objective. To identify the determinants of exclusive breastfeeding (EBF) among children under 6 months of age from three regions in the South and Grand'Anse Departments of Haiti. Methods. Data were pooled from three cross-sectional surveys conducted yearly from 2017 to 2019 with the guardians of 638 children under 6 months of age. A non-quantitative 24-hour dietary recall was used to assess EBF the day before the survey. Using unadjusted and adjusted prevalence ratios, associations were assessed between EBF and several explanatory factors: infant's age and sex; maternal age, educational attainment, mid-upper arm circumference (MUAC), dietary diversity, number of children under 5 years of age, responsibility for the main or secondary source of income of the household, initiation of breastfeeding within one hour, knowledge of EBF duration; household severe food insecurity, socioeconomic status, dependency ratio, region, and residential zone (urban/rural). Results. Prevalence of EBF was 68% in the study sample. From the fully adjusted model, prevalence of EBF was statistically significantly higher among younger infants, mothers with larger MUAC, who met or exceeded Minimum Dietary Diversity for Women (MDD-W), who initiated breastfeeding within one hour, who were knowledgeable of the recommendations for EBF duration, and living in the Jérémie region. Conclusions. The main determinants of EBF identified in this study attest to the importance of breastfeeding mothers' access to nutritious food for the practice and maintenance of EBF and the need for geographically equitable access to health services and education that support breastfeeding.

RESUMEN Objetivo. Determinar cuáles son los determinantes de la lactancia materna exclusiva en menores de 6 meses de edad de tres regiones de los departamentos Sur y Grand'Anse de Haití. Métodos. Se agruparon los datos de tres encuestas transversales realizadas anualmente entre 2017 y 2019 a representantes de 638 bebés menores de 6 meses de edad. Se empleó una descripción no cuantitativa de los alimentos consumidos en las últimas 24 horas para evaluar la lactancia materna exclusiva el día anterior a la encuesta. Mediante cocientes de prevalencia ajustados y no ajustados, se evaluó la relación entre la lactancia materna exclusiva y varios factores explicativos: sobre el lactante: edad y sexo; sobre la madre: edad, nivel educativo, circunferencia del brazo media, diversidad alimentaria, número de hijos menores de 5 años y responsabilidad como fuente principal o secundaria de ingresos del hogar; inicio de la lactancia materna en un plazo de una hora después del nacimiento y conocimiento sobre la duración de la lactancia materna exclusiva; inseguridad alimentaria grave en el hogar, situación socioeconómica y tasa de dependencia; y región y zona residencial (urbana/rural). Resultados. La prevalencia de la lactancia materna exclusiva fue de 68 % en la muestra del estudio. A partir del modelo totalmente ajustado, la prevalencia de la lactancia materna exclusiva fue significativamente mayor desde un punto de vista estadístico en los bebés más pequeños, las madres con una mayor circunferencia del brazo media, la que cumplieron o excedieron la Diversidad Alimentaria Mínima para las Mujeres, las que iniciaron la lactancia materna dentro de una hora después del parto, las que conocían bien las recomendaciones sobre la duración de la lactancia materna exclusiva y las que vivían en la región de Jérémie. Conclusiones. Los principales determinantes de la lactancia materna exclusiva identificados en este estudio confirman la importancia de que las madres lactantes tengan acceso a alimentos nutritivos para la práctica y el mantenimiento de la lactancia materna exclusiva, así como la necesidad de disponer de un acceso geográfico equitativo a los servicios de salud y la educación que respaldan la lactancia materna.

RESUMO Objetivo. Identificar os determinantes do aleitamento materno exclusivo (AME) entre crianças com menos de 6 meses de idade de três regiões dos departamentos Sul e Grand'Anse do Haiti. Métodos. Agruparam-se dados de três pesquisas transversais realizadas anualmente, de 2017 a 2019, com pais e responsáveis de 638 crianças com menos de 6 meses de idade. Um recordatório alimentar não quantitativo de 24 horas foi utilizado para avaliar o AME no dia anterior à pesquisa. Usando taxas não ajustadas e ajustadas de prevalência, avaliou-se a associação entre AME e diversos fatores explicativos: idade e sexo do bebê; idade da mãe, seu nível de escolaridade, circunferência do braço (CB), diversidade da dieta, número de filhos com menos de 5 anos, responsabilidade pela fonte primária ou secundária de renda da família, início do aleitamento materno na primeira hora, conhecimento sobre a duração do AME; insegurança alimentar domiciliar grave, status socioeconômico, índice de dependência, região e zona residencial (urbana/rural). Resultados. A prevalência de AME na amostra do estudo foi de 68%. Com base no modelo totalmente ajustado, a prevalência do AME foi maior, de forma estatisticamente significante, entre bebês mais jovens, mães com maior CB, que atendiam ou excediam a Diversidade Alimentar Mínima para Mulheres (MDD-W), que começaram a amamentar na primeira hora, que estavam familiarizadas com as recomendações sobre a duração do AME e que moravam na região de Jérémie. Conclusões. Os principais determinantes de AME identificados neste estudo atestam a importância do acesso das lactantes a alimentos nutritivos para a prática e a continuidade do AME, e a necessidade de acesso geograficamente equitativo a educação e serviços de saúde que apoiem o aleitamento materno.

Determinants of the interruption of exclusive breastfeeding at the 30th day after birth / Determinantes para a interrupção do aleitamento materno exclusivo aos 30 dias de vida

ABSTRACT Objective: To estimate the prevalence of exclusive breastfeeding (EBF), introduction of water, herbal teas, or other milks, as well as to identify the factors associated with the interruption of EBF at the 30th day after birth. Methods: This is a cross-sectional study using structured and pretested questionnaires applied to 310 mothers in two moments: in person, at the maternity ward; and at the time the infant was 30 days of age, by telephone call. Descriptive statistics and multivariate Poisson regression, following a multilevel hierarchical model according to the proximity to the outcome, were used to estimate the association between dependent and independent variables. Results: The maintenance of EBF at 30 days of age of the infant occurred in 85.2% of the sample, 1.6% receiving water, 11.5% herbal teas, and 8.2% other milk. Predictors for EBF interruption in the univariate analysis were the mothers' return to work or study activities shortly after the baby's birth (IR 2.88; 95%CI 1.14-7.25) and the use of a pacifier (IR 3.29; 95%CI 1.52-6.22). The interruption of EBF was lower in the group of participants who received support from the infant's maternal grandmother (IR 2.71; 95%CI 1.11-6.56) and their partner (IR 4.78; 95%CI 1.90-12.06). After a multivariate analysis, only the use of a pacifier (IR 5.47; 95%CI 2.38-19.3) and the partner's support (IR 6.87; 95%CI 2.04-23.1) maintained the association with the outcome. Conclusions: The prevalence of EBF found in this study can be considered good, and future interventions aimed at increasing the duration of EBF in this population should take into account the participation of the partner and the reinforcement for not introducing the pacifier.

RESUMO Objetivo: Estimar a prevalência de aleitamento materno exclusivo (AME), introdução de água, chás ou outros leites, bem como identificar os fatores associados à interrupção do AME aos 30 dias de vida. Métodos: Estudo transversal que utilizou questionários estruturados e pré-testados, aplicados a 310 mães em dois momentos: presencialmente, na maternidade, e aos 30 dias de vida da criança, mediante ligação telefônica. Estatística descritiva e regressão multivariada de Poisson, seguindo modelo hierárquico multiníveis conforme a proximidade com o desfecho, estimaram a associação entre as variáveis dependentes e independentes. Resultados: A manutenção do AME aos 30 dias de idade da criança ocorreu em 85,2% da amostra, e 1,6 % receberam água, 11,5 % chás e 8,2% outro leite. Preditores para a interrupção do AME na análise univariada foram o retorno das mães ao trabalho ou estudo logo após o nascimento do bebê (razão de incidência — RI 2,88; intervalo de confiança — IC95% 1,14-7,25) e o uso de chupeta (RI 3,29; IC95% 1,52-6,22). A interrupção do AME foi menor no grupo de participantes que recebeu apoio da avó materna do lactente (RI 2,71; IC95% 1,11-6,56) e do companheiro (RI 4,78; IC95% 1,90-12,06). Após a análise multivariada, apenas o uso de chupeta (RI 5,47; IC95% 2,38-19,3) e o apoio do companheiro (RI 6,87; IC95% 2,04-23,1) mantiveram associação com o desfecho. Conclusões: A prevalência de AME encontrada neste estudo pode ser considerada boa, e futuras intervenções que visem ao aumento da duração do AME nessa população devem levar em consideração a participação do companheiro e o reforço para a não introdução da chupeta.

Analysis of factors related to postoperative functional recovery after surgery of calcaneal fracture / 中华创伤骨科杂志

Objective:To analyze the factors influencing functional recovery after surgery of calcaneal fracture.Methods:A retrospective analysis was performed in 1,080 eligible patients with calcaneal fracture who had been admitted to The Third Hospital of Hebei Medical University from January 1, 2018 to December 31, 2020. They were 931 males and 149 females with a mean age of 43.0 years. By the Sanders classification, there were 107 cases of type Ⅰ, 343 cases of type Ⅱ, 471 cases of type Ⅲ and 159 cases of type Ⅳ. Multiple linear regression model was used to screen out the main relevant factors affecting the postoperative functional recovery by analyzing the 18 factors which might influence the postoperative functional recovery like gender, age, Sanders type, occupation, body mass index, season, cause, hospital stay, operation method, internal fixation, preoperative combined injury, preoperative complication, anesthesia, attendance to rehabilitation institution, incision selection, waiting time, preoperative blister and reduction quality.Results:All the 1,080 patients were followed up for 17.5 months on average. The mean Creighton-Nebraska score at the last follow-up was 88.4. The univariate analyses showed statistically significant differences in the Creighton-Nebraska score among patients with different gender, age group, Sanders type, occupation, injury cause, surgical method, preoperative combined injury, incision selection and reduction quality ( P<0.05). Multiple linear regression model analysis resulted in the following regression equation: Y=107.408-4.013×gender-7.101×age-1.214×Sanders type-1.606×incision selection. Conclusions:The factors which influence the functional recovery after surgery of calcaneal fracture may be gender, age, fracture type and incision selection; the functional recovery score after surgery of calcaneal fracture may be low for female senior patients with type Ⅳ fracture and a large L-shaped incision.
