Cyclic fatigue resistance of three reciprocating nickel-titanium instruments with heat treatment at intrachannel temperature

Introduction: the in vitro study compared the dynamic cyclic fatigue resistance of 3 reciprocating NiTi files with heat treatment. Methods: we distributed 30 new endodontic files in three groups. The endodontic files selected for this experiment were: AF Blue R3 25/06 (AFB) (Fanta Dental, Shanghai, China), X1 Blue File 25/06 (X1B) (MK Life, Porto Alegre, RS, Brazil), and Reciproc Blue 08/25 (RB) (VDW, Munich, Germany. We measured the time to file fractureand the length of the fractured fragment. ANOVA analysis was used, followed by the Tukey test for multiple comparisons, with a significance level of 5% (P < 0,05). Results: the mean time in seconds until the file fractured was 170.7 ±15,1 for AFB files, 110,4 ±26,8 for X1B, and 163,3 ±22,9 for RB files. This difference was statistically significant when comparing X1B to AFB (p: 0,000) and X1B to RB (p: 0,000). However, there are no statistically significant differences between RB and AFB (p:0,739). Conclussions: this study found that RB and AFB files exhibit similar resistance to cyclic fatigue.

Introducción: el estudio in vitro comparó la resistencia a la fatiga cíclica dinámica de 3 limas NiTi recíprocas con tratamiento térmico. Métodos: distribuimos 30 limas endodónticas nuevas en tres grupos. Las limas endodónticas seleccionadas para este experimento fueron: AF Blue R3 25/06 (AFB) (Fanta Dental, Shanghai, China), X1 Blue File 25/06 (X1B) (MK Life, Porto Alegre, RS, Brasil), y Reciproc Blue 08/25 (RB) (VDW, Munich, Alemania. Se midió el tiempo transcurrido hasta la fractura de la lima y la longitud del fragmento fracturado. Se utilizó el análisis ANOVA, seguido de la prueba de Tukey para comparaciones múltiples, con un nivel de significación del 5% (P < 0.05). Resultados: el tiempo medio en segundos hasta la fractura de la lima fue de 170.7 ±15.1 para las limas AFB, 110.4 ±26.8 para las X1B y 163.3 ±22.9 para las RB. Esta diferencia fue estadísticamente significativa al comparar X1B con AFB (p: 0.000) y X1B con RB (p: 0.000). Sin embargo, no hay diferencias estadísticamente significativas entre RB y AFB (p:0.739). Conclusiones: en este estudio se ha comprobado que las limas RB y AFB presentan una resistencia similar a la fatiga cíclica.

Intergenerational sex and early sexual debut are associated with HIV infection among transgender women in Paraguay.

INTRODUCTION: HIV prevalence among transgender women is high worldwide. The objectives of the present study were to estimate the current prevalence of HIV and identify factors associated with high HIV burden among transgender women in Paraguay. METHODS: Transgender women aged ≥15 years in four regions of Paraguay were recruited by Starfish sampling between February and March 2021. RESULTS: In total, 322 transgender women were included. Mean age was 31 years (range 15-67), and 102 had positive HIV test results (31.7%, 95% confidence interval [CI] 26.6-37.1). In multivariable analysis, factors associated with HIV infection were age at first intercourse ≤17 years (adjusted odds ratio [aOR] 5.47; 95% CI 1.05-28.42), >10 years difference in age with the last sexual partner (aOR 1.60; 95% CI 1.04-2.46), substance use (mostly cocaine) (aOR 3.00; 95% CI 1.47-6.12), higher risk perception (aOR 3.08; 95% CI 1.53-6.17), not testing for HIV (aOR 1.23; 95% CI 1.09-1.39), and accessed by a peer educator (aOR 3.86; 95% CI 1.77-8.38). CONCLUSIONS: Sexual debut as a minor and a large age difference with sexual partners are associated with high burden of HIV among transgender women in Paraguay. Our study corroborates the finding of cocaine use during sex as a risk factor for HIV. Prevention programmes must address structural and social vulnerabilities to stem the tragically high burden of HIV among transgender women.

Phylogeography and transmission of Mycobacterium tuberculosis spanning prisons and surrounding communities in Paraguay.

Recent rises in incident tuberculosis (TB) cases in Paraguay and the increasing concentration of TB within prisons highlight the urgency of targeting strategies to interrupt transmission and prevent new infections. However, whether specific cities or carceral institutions play a disproportionate role in transmission remains unknown. We conducted prospective genomic surveillance, sequencing 471 Mycobacterium tuberculosis complex genomes, from inside and outside prisons in Paraguay's two largest urban areas, Asunción and Ciudad del Este, from 2016 to 2021. We found genomic evidence of frequent recent transmission within prisons and transmission linkages spanning prisons and surrounding populations. We identified a signal of frequent M. tuberculosis spread between urban areas and marked recent population size expansion of the three largest genomic transmission clusters. Together, our findings highlight the urgency of strengthening TB control programs to reduce transmission risk within prisons in Paraguay, where incidence was 70 times that outside prisons in 2021.

Mental health issues and psychological risk factors among Paraguayan healthcare workers during the COVID-19 pandemic.

BACKGROUND: There is an increasing concern regarding the mental health of healthcare workers during the COVID-19 pandemic. AIMS: This study aimed to assess the psychological impact of the COVID-19 exposure among Paraguayan healthcare workers. METHODS: A cross-sectional descriptive study has been carried out in five hospitals of Paraguay. Demographic and occupational exposure to COVID-19 were collected through a short questionnaire. Mental health status was assessed with the GAD-7, the PHQ-9, and the PCL-C. Logistic regression was used to determine psychological risk factors. RESULTS: 432 participants were surveyed. 218 (50.46%) were physicians. The prevalence of symptoms of anxiety, depression and PTSD was 48.15, 41.90, and 5.79%, respectively. There were no significant differences in anxiety (128 [29.63%] vs. 80 [18.52%]; p = 0.3303), depression (102 [23.61%] vs. 79 [18.29%]; p = 0.6703), or PTSD (14 [3.24%] vs. 11 [2.55%]; p = 0.8074) between frontline versus second-line workers. Main risk factors associated with psychological distress included work experience <5 years for depression and a COVID-19 positive diagnosis or having family/friends with a COVID-19 positive diagnosis for PTSD. CONCLUSIONS: Paraguayan healthcare workers reported high prevalence of anxiety, depression, and a low prevalence of PTSD. A positive diagnosis of COVID-19 and work experience <5 years are important psychological risk factors.

Tuberculosis burden in indigenous population of Paraguay from 2018 to 2022

This study aims to report the epidemiological characterization, incidence, mortality and prognostic factors of tuberculosis in indigenous patients of Paraguay from 2018 to 2022. A retrospective cohort study was carried out with data extracted from the National Tuberculosis Program from January 2018 to June 2022. The clinical records of 1659 indigenous patients were included in the study. The indigenous population with tuberculosis in the period 2018-2022 was between 0 and 20 years old (25.4%), mostly female (54.6%), residing in Presidente Hayes (22.4%), and was from the rural area (74.3%), of the Mbya ethnic group (20.4%). The diagnosis was bacteriological in 69.2%, 96.1% had pulmonary location, 94.5% of the study population started treatment and 1.1% presented drug-resistance, while 88.3% corresponded to new cases. The highest number of new cases of tuberculosis in indigenous people was 336 in 2019. The incidence of tuberculosis was associated with age and area of residence, being more incident in the youngest and in the Presidente Hayes area. A total of 11.2% died, and the highest number of deaths occurred in 2019 with 47 cases (14%). We observed that the elderly, who did not start treatment, and who were coinfected with HIV were more likely to die from tuberculosis. The number of new cases and mortality from tuberculosis is high in the Paraguayan indigenous population. Age and coinfection with HIV continue to be risk factors for mortality.

Este estudio tiene como objetivo reportar la caracterización epidemiológica, incidencia, la mortalidad y los factores pronósticos de la tuberculosis en pacientes indígenas en Paraguay de 2018 a 2022. Se realizó un estudio de cohorte retrospectivo con datos extraídos del Programa Nacional de Tuberculosis desde enero 2018 hasta junio de 2022. Se incluyeron en el estudio las historias clínicas de 1.659 pacientes indígenas. La población indígena con tuberculosis en el período 2018-2022 presentaba las siguientes características: entre 0 y 20 años (25,4%), sexo femenino (54,5%), residente en Presidente Hayes (22,4%), del área rural (74,3%), y de la etnia Mbya (20,4%). El diagnóstico fue bacteriológico en el 69,2% y el 96,1% era de localización pulmonar, el 94,5% de la población estudiada inició tratamiento y el 1,1% presentó resistencia, el 88,3% correspondió a casos nuevos. El mayor número de casos nuevos de tuberculosis entre indígenas fue de 336 en 2019. La incidencia de tuberculosis estuvo asociada a la edad y zona de residencia, siendo más frecuente entre los más jóvenes y en la zona de Presidente Hayes. Murió un total del 11,2%, y el mayor número de muertes se produjo en 2019 con 47 casos (14%). Se constató que las personas mayores que no habían iniciado el tratamiento y que estaban coinfectadas con el VIH tenían más probabilidades de morir de tuberculosis. El número de casos nuevos y mortalidad por tuberculosis es alto en la población indígena paraguaya. La edad y la coinfección por el VIH siguen siendo factores de riesgo de mortalidad.

El objetivo del estudio fue identificar la resistencia del Mycobacterium tuberculosis a los fármacos en Paraguay, 2014 a 2017. Se realizó un estudio observacional retrospectivo. Se utilizaron los datos del Programa Nacional de Tuberculosis del Paraguay comprendidos entre los años 2014 a 2017. Se incluyeron todos los pacientes con diagnóstico de Tuberculosis que se realizaron un test de resistencia. Se extrajeron los datos en Excel y fueron analizados con Stata 17.0. Se incluyeron 3429 pacientes con tuberculosis que contaban con resultado de al menos una prueba de sensibilidad. La resistencia se encontró en 2.1% de los pacientes. La resistencia a la Rifampicina estuvo presente en el 0.3% de los casos mientras que a la Izionazida en el 0.6% de los casos. La prevalencia de resistencia fue más alta en hombres 3.4 (IC 95% 2.2 - 4.8) p=0.003, que residían en el chaco 6.0 (IC 95% 3.4 - 9.7) p=0.000, previamente tratados 2.7 (IC 95% 1.1 - 5.1) p=0.010. En el modelo se pudo observar que un paciente previamente tratado tiene mayores posibilidades de tener resistencia OR 2.62 (IC 95% 1.1 - 6.24). La prevalencia de resistencia del Mycobacterium tuberculosis a fármacos estuvo relacionada con haber sido previamente tratado

The objective of the study was to identify the resistance of Mycobacterium tuberculosis to drugs in Paraguay, 2014 to 2017. A retrospective observational study was carried out. The data from the National Tuberculosis Program of Paraguay between the years 2014 to 2017 were used. All patients with a diagnosis of Tuberculosis who underwent a resistance test were included. Data were extracted in Excel and analyzed with Stata 17.0. 3429 tuberculosis patients who had a result of at least one sensitivity test were included. Resistance was found in 2.1% of patients. Resistance to Rifampicin was present in 0.3% of cases while to Izionazide in 0.6% of cases. The prevalence of resistance was higher in men 3.4 (95% CI 2.2 - 4.8) p = 0.003, who resided in the Chaco 6.0 (95% CI 3.4 - 9.7) p = 0.000, previously treated 2.7 (95% CI 1.1 - 5.1) p = 0.010. In the model, it was observed that a previously treated patient has a greater chance of having resistance OR 2.62 (95% CI 1.1 - 6.24). The prevalence of resistance of Mycobacterium tuberculosis to drugs was related to having been previously treated

HIV prevalence and associated risk factors among men who have sex with men in three regions of Paraguay, 2020.

BACKGROUND: Our study aimed to measure HIV prevalence and associated risk factors among men who have sex with men (MSM) in three regions of Paraguay in 2020. METHODS: MSM were recruited for cross-sectional surveys in three regions of Paraguay using respondent-driven sampling. Interview were conducted face-to-face to collect demographic characteristics and risk and preventive behaviors. The analysis assessed HIV prevalence and associated risk factors in the three samples of MSM within each region. RESULTS: A total of 1,207 MSM were recruited, including 559 in Asunción-Central, 245 in Alto Paraná, and 403 in Caaguazú. HIV prevalence was 24.2% (95% CI 20.6-27.9) in Asunción-Central, 10.2% (95% CI 6.7-14.6) in Alto Paraná, and 3.2% (95% CI 1.7-5.4) in Caaguazú. In Asunción-Central, associations with HIV were age ≥25 years (1.86, 95% CI 1.15-3.00), being employed (1.82, 95% CI 1.07-3.11), self-reporting as homosexual (1.90, 95% CI 1.06-3.43), having sex with a known HIV-positive partner acquisition (4.19, 95% CI 2.37-7.43), self-perceived as being at higher risk for HIV acquisition (4.15, 95% CI 2.54-6.77), and able to access condoms and lubricants (1.82, 95% CI 1.08-3.05). In Alto Paraná, associations with HIV were self-reporting as homosexual (4.33, 95% CI 1.19-15.65) and having higher HIV knowledge (2.53, 95% CI 0.97-6.61). In Caaguazú, associations with HIV were self-reporting as homosexual (7.06, 95% CI 1.53-32.46) and being diagnosed with depression (4.68, 95% CI 0.89-24.43). CONCLUSIONS: HIV prevalence among MSM in Paraguay varied by region, being highest in the capital and major metropolitan area of Asunción-Central, followed by the border area of Alto Paraná. While being self-identified as homosexual was associated with HIV in all three regions, other associations differed, indicating prevention programs need to be tailored to the locale.

Hábitos alimentarios y estrés académico en estudiantes universitarios durante la pandemia del COVID-19, Paraguay 2021

RESUMEN El objetivo del estudio fue identificar los hábitos alimentarios relacionados al nivel de estrés de los estudiantes de la Universidad Nacional de Caaguazú durante la pandemia del COVID-19. Se realizó un estudio descriptivo, observacional, de corte transversal donde se seleccionaron 353 estudiantes de las diferentes facultades. Se estudiaron las variables demográficas, los hábitos alimentarios y el estrés académico. Se incluyeron en el estudio 353 estudiantes universitarios, 64,9% del sexo femenino, 59,5% menores de 23 años. El 36,5% pertenecía a la facultad de ciencias de la producción mientras que el 29,7% fue del tercer año. En total el 64,8% (229 estudiantes) tuvieron nivel de estrés alto. El nivel de estrés alto estuvo relacionado a un alto consumo de dulces (AOR= 2,94, 1,57-5,51), alto consumo de comida rápida (AOR= 2,23, 1,14-4,32), bajo consumo de frutas (AOR= 1,66, 0,99-2,79), saltarse el almuerzo (AOR= 2,94, 1,55-5,60) y el aumento de las colaciones diarias (AOR= 3,36, 1,74- 6,47). Los resultados de nuestro estudio visibilizaron la problemática de que el estrés académico durante la pandemia del COVID-19 influyó en la adquisición de malos hábitos alimentarios.

ABSTRACT The objective of the study was to identify the eating habits related to the level of stress among students of the National University of Caaguazú during the COVID-19 pandemic. A descriptive, observational, cross-sectional study was carried out with 353 students selected from different faculties. Demographic variables, eating habits and academic stress were studied. A total of 353 university students were included in the study, 64.9% female, and 59.5% under 23 years of age. 36.5% belonged to the Faculty of Production Sciences while 30% were from the third year. In total, 64.8% (229 students) had a high level of stress. High stress level was related to high consumption of sweets (AOR= 2.94, 1.57-5.51), high consumption of fast food (AOR= 2.23, 1.14-4.32), low consumption of fruits (AOR= 1.66, 0.99-2.79), skipping lunch (AOR= 2.94, 1.55-5.60), and increased daily snacks (AOR= 3.36, 1.74-6.47). The results of our study made visible the problem that academic stress during the Covid-19 pandemic influenced the acquisition of bad eating habits.

Factores asociados a la mortalidad por tuberculosis en indígenas en Paraguay, 2014 a 2019

Introducción: La tasa de mortalidad estimada de tuberculosis (TBC) en Paraguay en 2019 fue de 3,9 por 100.000 habs. Las comunidades indígenas presentan un elevado riesgo de padecer TBC. Objetivo: Determinar los factores asociados a la mortalidad en personas de origen indígena con diagnóstico de TBC en Paraguay, 2014-2019. Métodos : Se realizó un estudio observacional retrospectivo. Se utilizaron los datos del Programa Nacional de Control de la TBC del Paraguay comprendidos entre los años 2014 y 2019. Se registraron los datos sociodemográficos y factores de riesgo. Resultados: Se incluyeron 2.210 personas de origen indígena con diagnóstico de TBC, el 53,8% fue de sexo masculino, entre 20 y 39 años (32,3%) y 0 a 19 años de edad (30,2%), la localización de la TBC fue mayoritariamente pulmonar (92,3%). Durante el 2014 a 2019 se observaron 217 muertes (9,8%). Los factores asociados a mortalidad en pacientes con TBC fueron la edad (adOR = 13,95; CI: 7,07-27,55 mayor a 80 años), (adOR = 4,20; CI: 2,59-6,82 mayor a 60 años) y (adOR = 3,30; CI: 2,06-5,28 para 40 a 59 años), la co-infección VIH (adOR =), y la localización de la TBC (adOR = 3,60; CI: 1,88-6,90 para TBC diseminada). Conclusión: La mayor edad, el diagnóstico de co-infección VIH y localización de la TBC diseminada, están asociados a un mayor riesgo de muerte en población indígena con TBC.

Background: The estimated tuberculosis (TB) mortality rate in Paraguay in 2019 was 3.9 per 100,000 people. Indigenous communities are at high risk for TB. Aim: To determine the factors associated with mortality in indigenous people with a diagnosis of TB in Paraguay, 2014-2019. Methods: A retrospective observational study was done. sociodemographic data and risk factors data from the National TB Program of Paraguay between the years 2014 to 2019 were used. Results: A total of 2,210 indigenous people with a diagnosis of TB were included, 53,8% were male, between 20 to 39 (32.3%) and 0 to 19 years old (30.2%), the localization of TBC was majority pulmonary (92.3%). During 2014 to 2019 the were 217 deaths (9.8%). The factors associated to mortality in TB patients were the age (adOR = 13.95; CI: 7.07-27.55 older than 80 years), (adOR = 4.20; CI: 2.59-6.82 older than 60 years), and (adOR = 3.30; CI: 2.06 - 5.2840 to 59 years), HIV co-infection (adOR = 7.07; CI 3.74-13.87), and localization of TB (adOR = 3.60; CI: 1.88-6.90 for disseminated TB). Conclusion: Older age, HIV co-infection and disseminated localization of TBC are associated with a higher risk of death in indigenous people with TB.

Carica papaya mouthrinse as an inhibitor of Streptococcus mutans: Randomized controlled clinical trial.

PURPOSE: To evaluate the effect of Carica papaya mouthrinse as an inhibitor of Streptococcus mutans. METHODS: This was a double blind (subject and evaluator) randomized controlled trial in 40 subjects distributed in two groups: Carica papaya mouthrinse intervention (n= 20) or chlorhexidine (n= 20). The antibacterial effect was determined by counting colony-forming units per milliliter (CFU/ml) of S. mutans in saliva sample cultures; taken both before mouthrinse, immediately after 10 minutes mouthrinsing, and 8 days after mouthrinsing. The data was statistically analyzed with Student's t-test (P ≤ 0.05). RESULTS: The difference before and immediately after (10 minutes) use of Carica papaya mouthrinse was of 764 CFUs. After 8 days use the difference was 212 CFUs. For the control group (0.12% chlorhexidine) the difference before and immediately after use (10 minutes) was 683 CFUs. After 8 days use the difference was 455 CFU. When comparing between groups applying t-test, no statistical differences were found in the (CFU/ml) of S. mutans before and after 10 minutes mouthrinse (P= 0.8060), 10 minutes and 8 days after mouthrinsing (P= 0.7104) before and 8 days after mouthrinsing (P= 0.4419). CLINICAL SIGNIFICANCE: Carica papaya could be an alternative mouthrinse for the inhibition of Streptococcus mutans.

Antibacterial effect of green tea infusion used as a mouthwash on saliva and bacterial plaque: a randomized controlled trial.

The objective of this study was to evaluate the antibacterial effect of a green tea infusion used as a mouthwash. In this double-blind, randomized controlled study, simple randomization was used to divide 28 students, 18 to 40 years of age, into 2 groups (n = 14): green tea (intervention) or distilled water (placebo). A 13% green tea infusion was prepared with 13 g of green tea (commercially fractionated) in 100 mL of saline solution at a temperature of approximately 90°C. The liquid was poured into sterile glass containers, as was the distilled water for the control group. The antibacterial effect was determined by counting the colony-forming units in cultures of plaque and saliva samples, which were obtained before and immediately after the students rinsed their mouth once with 10 mL of the green tea or control solution. The data were subjected to t tests to analyze differences before and after the intervention and between groups (green tea versus distilled water) (P < 0.05). The analysis showed statistically significant differences between the groups (P < 0.05), with participants in the green tea group demonstrating greater reductions in the numbers of colony-forming units. Green tea mouthwash had an antibacterial effect on saliva and bacterial plaque, suggesting that green tea mouthwash could be a beneficial addition to standard oral hygiene measures.

Serie de Casos de Leishmaniasis Detectados en Centros Hospitalarios del Departamento de Caaguazú, Paraguay en 2019

Resumen La leishmaniasis es la tercera de las enfermedades de transmisión vectorial a humanos en importancia por el número de casos y la población en riesgo. En Paraguay la leishmaniasis cutánea es una enfermedad endémica atribuida en casi todos los casos a Leishmania (Viannia) braziliensis. El objetivo del artículo es describir las características demográficas y clínicas de una serie de casos de pacientes con leishmaniasis en el V departamento de Caaguazú y departamentos cercanos, epidemiológicamente endémicos. Se reportan casos diagnosticados en los meses enero a diciembre del año 2019. Los casos se presentaron en el departamento de Caaguazú, abarcando los diferentes distritos que componen y departamentos cercanos como Canindeyú, Alto Paraná y Guaira. De los casos registrados (9 casos) fueron hombres y (6 casos) tuvieron entre 50 a 70 años de edad. La lesión estuvo situada mayormente en el tabique nasal en 8 casos, con una evolución de menos de 10 años (6 casos) y en 4 casos dejo cicatriz. Solo 3 casos completaron su tratamiento. Se sugiere realizar el reporte de casos para tener un panorama de los casos de leishmaniasis en Paraguay como vigilancia sanitaria de la enfermedad y localizar focos de contagio.

Abstract Leishmaniasis is the third most important vector-borne diseases in humans due to the number of cases and the population at risk. In Paraguay, cutaneous leishmaniasis is an endemic disease attributed in almost all cases to Leishmania (Viannia) braziliensis. The objective of the article was to describe the demographic and clinical characteristics of a series of cases of patients with leishmaniasis in the V department of Caaguazú and nearby departments, epidemiologically endemic. Cases diagnosed in the months of January to December of the year 2019 are reported. The cases occurred in the department of Caaguazú, covering the different districts that make up and nearby departments such as Canindeyú, Alto Paraná and Guaira. Of the registered cases (9 cases) were men and (6 cases) were between 50 and 70 years of age. The lesion was located mainly in the nasal septum in 8 cases, with an evolution of less than 10 years (6 cases) and in 4 cases it left a scar. Only 3 cases completed their treatment. It is suggested to carry out the case report to have an overview of Leishmania cases in Paraguay as a health surveillance of the disease and to locate sources of contagion.

Prevalencia y factores de riesgo para sífilis en población indígena masculina de Paraguay, 2017 / Prevalence and risk factors for syphilis in male indigenous population of Paraguay, 2017

Resumen: Objetivo: Determinar la prevalencia y los factores de riesgo para sífilis en población indígena masculina de Paraguay durante el año 2017. Material y métodos: Se realizó un estudio observacional, descriptivo, con muestro probabilístico, estratificado y multietápico. Fueron incluidos indígenas de sexo masculino, mayores de 15 años de edad, de cinco familias lingüísticas residentes en Paraguay durante el periodo de estudio. Resultados: La prevalencia de sífilis en hombres de la población indígena de Paraguay fue de 4.50%. Los indígenas que tenían entre 15 y 20 años tuvieron 2.70 probabilidades de presentar sífilis. Asimismo, los participantes que reportaron múltiples parejas en el último año, sexo transaccional y consumir alcohol en la última relación sexual tuvieron 2.69, 3.06 y 2.16 veces la probabilidad de presentar sífilis, respectivamente. Conclusiones: Se encontró una prevalencia moderada de sífilis en la población indígena masculina. La prevalencia fue de dos veces más para aquéllos que tenían más de dos parejas sexuales, sexo transaccional y que involucraban alcohol durante la práctica sexual.

Abstract: Objective: To determine the prevalence and risk factors for syphilis transmission of the male indigenous population of Paraguay during 2017. Materials and methods: An observational, descriptive cross-sectional study was conducted with multi-epic stratified probabilistic sampling. They were included in the study indigenous male, over 15 years of age, of five linguistic families resident in Paraguay during the study period. Results: The prevalence of syphilis in men of the indigenous population of Paraguay was 4.50%. Indigenous people who were 15 to 20 years old had 2.70 times the probability of presenting syphilis, as well as the participants who reported multiple partners in the last year, transaccional sex and consumed alcohol in the last sexual intercourse had 2.69, 3.06 and 2.16 times the probability of presenting syphilis. Conclusions: A moderate prevalence of syphilis was found in the male indigenous population. In turn, an opportunity was found twice more to acquire syphilis infection for those who had more than two sexual partners, transactional sex and those who involved alcohol during sexual practice.

Psychological impact of COVID-19 pandemic among healthcare workers in Paraguay: A descriptive and preliminary study

ABSTRACT Introduction: Healthcare workers exposed to SARS-CoV-2 are vulnerable to psychological distress. Methodology: A descriptive cross-sectional study was carried out in 5 tertiary hospitals in the Central, San Pedro and Caaguazú Departments of Paraguay during the COVID-19 pandemic from April to June 2020. The pilot study included 125 healthcare workers as participants, 25 for each hospital. Demographic data and occupational exposure data were collected with an ad-hoc questionnaire. Symptoms of depression and anxiety were evaluated employing the Patient Health Questionnaire-9, and the Generalized Anxiety Disorder scale-7. The prevalence of post-traumatic stress was determined using the Post-Traumatic Stress Disorder Check List-C. Results: Of the 125 participants, 68 (54.8%) were doctors, 37 (29.8) nurses, 7 (5.6%) biochemists, 3 (2.4%) obstetricians, and 9 (7.3%) other healthcare workers. Most participants were females (86 (68.8%)), with an average age of 33.8 years (SD ± 7.4), single (71 (56.8%)), with a postgraduate educational level (83 (66.4%)), and reporting a junior level of work experience (52 (41.6%)). A total of 71 (57.3%) were classified as high-risk healthcare workers after exposure to SARS-CoV-2. 61 (48.8%) of participants presented symptoms of depression, and 68 (54.4%) presented symptoms of anxiety. A small group reported symptoms of post-traumatic stress (9 (7.2%)). Conclusion: Healthcare workers in Paraguay reported a significant prevalence of depressive and anxious symptoms during the COVID-19 pandemic. These findings lend support to the idea that healthcare workers are vulnerable to psychological distress and that they may require specific mental health interventions.

RESUMEN Introducción: los trabajadores de la salud expuestos al SARS-CoV-2 son vulnerables a la angustia psicológica.
