Patrón de neumonía organizativa en TC de tórax: prevalencia y asociación con resultados clínicos en una cohorte de pacientes con COVID-19 grave/crítico / Organizing Pneumonia Pattern on Chest CT: Prevalence and Association with Clinical Outcomes in a Cohort of Patients with Severe/Critical COVID-19

Introducción: La neumonía por COVID-19 puede presentarse con dos patrones radio-lógicos: daño alveolar difuso o neumonía organizativa. Estos patrones tienen diferente evolución y pronóstico en pacientes sin infección por COVID-19. Nuestro objetivo fue evaluar la prevalencia del patrón radiológico de neumonía organizativa y su asociación con los desenlaces clínicos.Métodos: Se realizó un estudio de cohorte retrospectivo que incluyó a pacientes adultos hospitalizados por COVID-19 grave/crítica a los que se les realizó una tomografía computarizada de tórax en los 21 días posteriores al diagnóstico. Los patrones radiológicos fueron revisados y clasificados por dos radiólogos expertos. Resultados: De los 80 pacientes incluidos, el 89% (n=71) presentaron un patrón compatible con neumonía organizativa. Los principales hallazgos radiológicos fueron la distribución multilobar (98,7%) y bilateral (97,6%) con opacidades en vidrio esmerilado (97,6%). El 44% (n=33) de los sujetos requirió ingreso en cuidados intensivos, de los cuales el 24% (n=19) recibió ventilación mecánica. La presencia de neumonía organizativa se asoció de forma independiente con una disminución de las probabilidades de ventilación mecánica o muerte (Odds ratio 0,14; intervalo de confianza del 95%: 0,02 - 0,96; valor de p 0,045) en un modelo multivariado que incluía la edad, el sexo, el IMC y la afectación pulmonar en la TC.Conclusiones: Un patrón radiológico de neumonía organizativa es altamente prevalen-te en pacientes con COVID-19 grave/crítico y se asocia con mejores resultados clínico

Introduction: COVID-19 pneumonia can present with two distinct radiologic patterns: diffuse alveolar damage or organizing pneumonia. These patterns have been linked to different outcomes in non-COVID-19 settings. We sought to assess the prevalence of organizing pneumonia radiologic pattern and its association with clinical outcomes. Methods: We performed a retrospective cohort study including adult patients hospita- lized for severe/critical COVID-19 who underwent chest computed tomography within 21 days of diagnosis. Radiologic patterns were reviewed and classified by two expert radiologists. Results: Among 80 patients included, 89% (n=71) presented a pattern consistent with organizing pneumonia. The main radiologic findings were multilobar (98.7%) and bilateral (97.6%) distribution with ground glass opacities (97.6%). Intensive care admission was required for 44% (n=33) of subjects, of which 24% (n=19) received mechanical ventilation. The presence of organizing pneumonia was independently associated with a decreased odds of mechanical ventilation or death (Odds ratio 0.14; 95% confidence interval 0.02 - 0.96; p value 0.045) in a multivariate model including age, gender, BMI and lung involvement on CT. Conclusion: A radiologic pattern of organizing pneumonia is highly prevalent in patients with severe/critical COVID-19 and is associated with improved clinical outcomes.

Introducción. El examen genital en varones es una evaluación clínica simple y rápida para detectar patología urogenital. Los datos sobre prevalencia de patología urogenital en varones adolescentes son limitados. Nuestro objetivo fue describir la prevalencia de patología urogenital en varones adolescentes. Población y métodos. Estudio descriptivo transversal en el Servicio de Adolescencia de un hospital público de la Ciudad de Buenos Aires. Se evaluaron retrospectivamente las historias clínicas (HC) de varones de 9 a 20 años atendidos entre 2008 y 2018; se incluyeron las que tenían examen genital. Se recabaron datos de edad, estadio puberal, orquidometría, patología urogenital antes de la adolescencia y al momento de la consulta. La prevalencia se expresó en porcentaje e intervalo de confianza del 95 % (IC95%). Se estimó necesario incluir 1167 HC como muestra poblacional. Resultados. Se evaluaron 2129 HC; se incluyeron 1429. En 686 casos no se hizo el examen genital. La población tuvo una mediana de edad de 12 años (rango intercuartílico 11-14 años). En 72 varones (5,7 %; IC95% 4,5-7,2), se halló una enfermedad genitourinaria antes de la adolescencia. Se detectó al menos una patología urogenital en 272 adolescentes (14,8 %; IC95% 13,1-16,7); las más frecuentes fueron adherencia balanoprepucial 5,3 % (IC95% 4,2-6,6), varicocele 2,7 % (IC95% 2-3,7) y fimosis 1,8 % (IC95% 1,2-2,6). Conclusiones. El examen genital permitió detectar que el 14,8 % de los varones adolescentes atendidos presentó alguna patología urogenital. Las entidades más frecuentes fueron adherencia balanoprepucial, varicocele y fimosis.

Introduction. The male genital exam is a simple and quick assessment to look for urogenital disease. Data on the prevalence of urogenital disease in male adolescents are limited. Our objective was to describe the prevalence of urogenital disease in male adolescents. Population and methods. Descriptive, cross-sectional study conducted at the Department of Adolescenceof a public hospital in the City of Buenos Aires. The medical records of male patients aged 9 to 20 years seen between 2008 and 2018 were retrospectively reviewed; all those with a genital exam were included. Data on age, pubertal stage, orchidometry, and urogenital disease before adolescence and at the time of consultation were recorded. The prevalence was described as percentage and 95% confidence interval (CI).As per estimations, 1167 medical records had to be included to establish the population sample. Results. A total of 2129 medical records were assessed and 1429 were included. No genital exam had been conducted in 686 cases. The median age of the population was 12 years (interquartile range: 11­14 years). Urogenital disease before adolescence was detected in 72 boys (5.7%; 95% CI: 4.5­7.2). Urogenital disease was found in 272 adolescents (14.8%; 95% CI: 13.1­16.7); the most common conditions were balanopreputial adhesions in 5.3% (95% CI: 4.2­6.6), varicocele in 2.7% (95% CI: 2­3.7), and phimosis in 1.8% (95% CI: 1.2­2.6). Conclusions. A genital exam allowed to detect that 14.8% of adolescent boys had a urogenital diseaseThe most common conditions were balanopreputial adhesions, varicocele, and phimosis.

Prevalencia de cáncer de vesícula en pacientes pos operados de colecistectomía en un Hospital de Tercer Nivel en el 2021 en Paraguay / Prevalence of gallbladder cancer in patients undergoing cholecystectomy in a Third-Level Hospital in 2021 in Paraguay

Introducción: El cáncer de vesícula biliar (CVB) es la neoplasia más frecuente de las vías biliares, su diagnóstico suele hacerse de forma tardía llevando a una reducción en las opciones terapéuticas y alta mortalidad. La importancia de hacer un diagnóstico oportuno es la mejoría en el pronóstico debido a mayores opciones terapéuticas e incluso curación de la enfermedad, lo que hace muy relevante conocer la prevalencia de CVB en pacientes colecistectomizados. Objetivos: Determinar la prevalencia del cáncer de vesícula en la anatomía patológica de pacientes colecistectomizados en el Hospital General de Barrio Obrero en el año de 2021. Materiales y métodos: Estudio observacional, descriptivo, retrospectivo y de corte transversal, con datos colectados de los expedientes clínicos: edad, sexo, motivo de consulta, antecedentes patológicos personales y patologías basales, hallazgo operatorio y resultados de anatomía patológica. Los datos fueron cargados en una planilla Excel y analizados estadísticamente. Resultados: Se diagnosticaron 2 carcinomas mal diferenciados (3,5%) de todas las colecistectomías. El promedio de edad fue de 39a (DS +/- 14;16), sexo femenino (63%). Las comorbilidades más frecuentes fueron obesidad (58,7%), hipertensión arterial (33,8%), diabetes y dislipidemia (12,8% cada). Conclusión: El cáncer de vesícula biliar tiene una alta prevalencia regional, debido a factores de riesgo relacionados al estilo de vida y dieta. El hallazgo más llamativo fue encontrar con una mayor prevalencia en el grupo de edad entre 31-50 años en lugar de mayores a 60 años.

Introduction: Gallbladder cancer (CVB) is the most common neoplasm of the bile ducts; its diagnosis is usually made late, leading to a reduction in therapeutic options and high mortality. The importance of making a timely diagnosis is the improvement in prognosis due to greater therapeutic options and even cure of the disease, which makes it very relevant to know the prevalence of CVB in cholecystectomized patients. Objectives: Determine the prevalence of gallbladder cancer in the pathological anatomy of cholecystectomized patients at the Barrio Obrero General Hospital in the year 2021. Materials and methods: Observational, descriptive, retrospective and cross-sectional study, with data collected from clinical records: age, sex, reason for consultation, personal pathological history and baseline pathologies, operative finding and pathological anatomy results. The data were loaded into an Excel spreadsheet and analyzed statistically. Results: 2 poorly differentiated carcinomas were diagnosed (3.5%) of all cholecystectomies. The average age was 39 years (SD +/- 14;16), female (63%). The most frequent comorbidities were obesity (58.7%), high blood pressure (33.8%), diabetes and dyslipidemia (12.8% each). Conclusion: Gallbladder cancer has a high regional prevalence, due to risk factors related to lifestyle and diet. The most striking finding was a higher prevalence in the age group between 31-50 years rather than those over 60 years of age.

Introducción. El sobrepeso y la obesidad infantil constituyen un problema de salud pública. El inicio de la pandemia por COVID-19 pudo haber favorecido esta patología. El puntaje Z del índice de masa corporal (Z-IMC) es un indicador aceptado para su diagnóstico y seguimiento. Objetivo. Evaluar si la prevalencia de sobrepeso y obesidad, y el Z-IMC en niños de 2 a 5 años aumentó durante la pandemia. Población y métodos. Estudio de cohorte retrospectiva. Se incluyeron pacientes asistidos en efectores públicos de salud del Gobierno de la Ciudad Autónoma de Buenos Aires (GCABA), de 2 a 5 años de edad, con registro de peso y talla en dos consultas, antes y después de haber comenzado el aislamiento social preventivo y obligatorio (ASPO). Se registró estado nutricional (Z-IMC) y variación del Z-IMC entre ambas consultas. Resultados. Se evaluaron 3866 sujetos, edad promedio 3,4 ± 0,8 años; el 48,1 % fueron mujeres. El intervalo promedio entre consultas fue 14,3 ± 2,5 meses. La prevalencia de sobrepeso/obesidad aumentó del 12,6 % (IC95% 11,6-13,6) al 20,9 % (IC95% 19,6-22-2); p <0,001, al igual que el Z-IMC (0,4 ± 1,1 vs. 0,8 ± 1,3; p <0,001). Conclusión. La prevalencia de sobrepeso y obesidad, y el Z-IMC en niños de 2 a 5 años aumentó significativamente durante la pandemia.

Introduction. Childhood overweight and obesity are a public health problem. The onset of the COVID-19 pandemic may have contributed to this condition. The body mass index (BMI) Z-score has been accepted as an indicator for overweight and obesity diagnosis and follow-up. Objective. To assess whether the prevalence of overweight and obesity and the BMI Z-score in children aged 2 to 5 years increased during the pandemic. Population and methods. Retrospective, cohort study. Patients included were those seen at public health care facilities in the City of Buenos Aires (CABA), who were aged 2 to 5 years, had weight and height values recorded at 2 different visits, before and after the establishment of the preventive and mandatory social isolation policy. Patients' nutritional status (BMI Z-score) and the variation in this indicator between both visits were recorded. Results. A total of 3866 subjects were assessed; their average age was 3.4 ± 0.8 years; 48.1% were girls. The average interval between both visits was 14.3 ± 2.5 months. The prevalence of overweight/ obesity increased from 12.6% (95% CI: 11.6­13.6) to 20.9% (95% CI: 19.6­22.2), p < 0.001, and so did the BMI Z-score (0.4 ± 1.1 versus 0.8 ± 1.3, p < 0.001). Conclusion. The prevalence of overweight and obesity and the BMI Z-score in children aged 2 to 5 years increased significantly during the pandemic.

Prevalencia de Staphylococcus aureusy su sensibilidad antibiótica en aislamientos en infecciones de piel y partes blandas en pacientes ambulatorios / Staphylococcus aureus prevalence and antimicrobial susceptibility in isolates from skin and soft tissue infections in outpatients

ntroducción: Las infecciones de piel y partes blandas (IPPB) constituyen la tercera causa de consulta en nuestro centro. S.aureus es el agente etiológico más frecuente en este tipo de infecciones y la meticilino resistencia es clínicamente el mecanismo de resistencia más importante. El objetivo de este trabajo fue analizar la prevalencia de los distintos agentes etiológicos en IPPB en pacientes ambulatorios, así como también estudiar su sensibilidad a los antibióticos y resistencias acompañantes más frecuentes. Materiales y métodos: Estudio descriptivo y retrospectivo que incluyó todas las muestras provenientes de IPPB de pacientes ambulatorios desde octubre de 2017 a abril de 2022. Resultados: Se obtuvieron 180 cultivos positivos de muestras provenientes de IPPB durante el periodo estudiado, 12 fueron infecciones polimicrobianas. En total se obtuvieron 307 aislamientos: el microorganismo aislado con mayor frecuencia fue S.aureus (111; 36,2%). Se hallaron 71 SAMR (64%) y 40 SAMS (36%). De los SAMR, 67 (95%) fueron comunitarios (SAMRC) por criterios microbiológicos, y 4 SAMR hospitalarios (5%). De las cepas SAMRC, 44 (66%) no presentaron resistencias acompañantes, 15 (22% ) fueron resistentes a eritromicina, 12 (18%) a gentamicina y 7 (10%) a clindamicina. Conclusiones: El microorganismo más frecuentemente aislado en IPPB en pacientes ambulatorios fue el S.aureus y 67 aislamientos fueron categorizados como SAMRC por lo cual es necesario considerar al SAMRC como un patógeno frecuente. Debido a la baja resistencia hallada para CLI y TMS ambos podrían ser de elección en el tratamiento empírico en las IPPB en pacientes ambulatorios

Background:S. aureus is the main cause of skin and soft tissues infections (SSTIs) in immunocompetent patients. This type of infection is the third cause of medical consultation in our center. Our objective was to evaluate the prevalence of S. aureus, as well as its sensitivity to antimicrobials, isolated from skin and soft tissue samples from outpatients at an interzonal general acute care hospital located in Buenos Aires, Argentina.Methods: Descriptive and retrospective study that included all outpatient SSTIs samples from October 2017 to April 2022.Results: We obtained 215 positive cultures of samples from SSTIs during the study period. Of a total of 276 isolates: the most frequently isolated microorganism wasS. aureus (111; 40.22%). The prevalence of S. aureuswas 51.63%. We found 71 MRSA (63.96%). Of the SAMR strains, 60.56% did not present accompanying resistance, and only 8 isolates (11.27%) showed resistance to clindamycin. All SAMRs remained sensitive to minocycline and trimethoprim-sulfamethoxazole.Conclusions: The most frequently isolated microorganism in SSTIs was S. aureus and 71 isolates were categorized as SAMR, therefore it is necessary to consider SAMR as a frequent pathogen. Due to the low resistance found for CLI and TMS, they should be considered for empirical treatment in SSTIs in outpatients

Prevalencia de osteopenia del prematuro antes y después de la implementación de una estrategia temprana de manejo fosfocálcico / Prevalence of osteopenia of prematurity before and after implementing an early strategy with the use of calcium and phosphate

Introducción. Con el uso de la nutrición parenteral agresiva en recién nacidos de muy bajo peso, se detectaron alteraciones del metabolismo fosfocálcico. En 2016 se implementó una estrategia de prevención a través del monitoreo fosfocálcico y su suplementación temprana. El objetivo fue estudiar si esta estrategia disminuye la prevalencia de osteopenia e identificar factores de riesgo asociados. Población y métodos. Estudio cuasiexperimental que comparó la prevalencia de osteopenia entre dos grupos: uno después de implementar la estrategia de monitoreo y suplementación fosfocálcica (01/01/2017-31/12/2019), y otro previo a dicha intervención (01/01/2013-31/12/2015). Resultados. Se incluyeron 226 pacientes: 133 pertenecen al período preintervención y 93 al posintervención. La prevalencia de osteopenia global fue del 26,1 % (IC95% 20,5-32,3) y disminuyó del 29,3 % (IC95% 21,7-37,8) en el período preintervención al 21,5 % (IC95% 13,6-31,2) en el posintervención, sin significancia estadística (p = 0,19). En el análisis multivariado, el puntaje NEOCOSUR de riesgo de muerte al nacer, recibir corticoides posnatales y el período de intervención se asociaron de manera independiente a osteopenia. Haber nacido luego de la intervención disminuyó un 71 % la probabilidad de presentar fosfatasa alcalina >500 UI/L independientemente de las restantes variables incluidas en el modelo. Conclusión. La monitorización y suplementación fosfocálcica precoz constituye un factor protector para el desarrollo de osteopenia en recién nacidos con muy bajo peso al nacer.

Introduction. With the use of aggressive parenteral nutrition in very low birth weight infants, alterations in calcium and phosphate metabolism were detected. In 2016, a prevention strategy was implemented through calcium phosphate monitoring and early supplementation. Our objective was to study whether this strategy reduces the prevalence of osteopenia and to identify associated risk factors. Population and methods. Quasi-experiment comparing the prevalence of osteopenia between two groups: one after implementing the calcium phosphate monitoring and supplementation strategy (01/01/2017­12/31/2019) and another prior to such intervention (01/01/2013­12/31/2015). Results. A total of 226 patients were included: 133 in the pre-intervention period and 93 in the post-intervention period. The overall prevalence of osteopenia was 26.1% (95% CI: 20.5­32.3) and it was reduced from 29.3% (95% CI: 21.7­37.8) in the pre-intervention period to 21.5% (95% CI: 13.6­31.2) in the post-intervention period, with no statistical significance (p = 0.19). In the multivariate analysis, the NEOCOSUR score for risk of death at birth, use of postnatal corticosteroids, and the intervention period were independently associated with osteopenia. Being born after the intervention reduced the probability of alkaline phosphatase > 500 IU/L by 71%, regardless of the other variables included in the model. Conclusion. Calcium phosphate monitoring and early supplementation is a protective factor against the development of osteopenia in very low birth weight infants.

Epidemiología de la apendicitis aguda en Colombia: Un análisis de las bases de datos administrativas del Ministerio de Salud / Epidemiology of acute appendicitis in Colombia: An Analysis of the Ministry of Health administrative databases

Introducción. La apendicitis aguda es una afección común, con un pico de incidencia entre los 10 y 20 años. La cirugía es el tratamiento preferido y la apendicectomía por laparotomía sigue siendo el estándar, aunque el abordaje laparoscópico ha mostrado menos complicaciones. El objetivo de este artículo fue caracterizar tanto la enfermedad como el tratamiento quirúrgico en Colombia, usando datos de bases oficiales. Métodos. Se accedió a la base de datos del Sistema Integrado de Información para la Protección Social (SISPRO) del Ministerio de Salud de Colombia en febrero de 2023. Se recogieron datos de los pacientes con diagnóstico de apendicitis y con procedimiento de apendicectomía entre 2017 y 2021, y se analizaron por edad, sexo y ubicación geográfica. Resultados. Entre 2017 y 2021 se diagnosticaron 345.618 casos de apendicitis (51,8 % mujeres), con pico de incidencia a los 15-20 años. Se realizaron 248.133 apendicectomías, el 16,7 % por laparoscopia. Los hospitales con más procedimientos reportados estaban en Bogotá, Yopal, Popayán y Florencia. La mortalidad fue de 0,56 % en hombres y 0,51 % en mujeres. Conclusión. La apendicitis es común, con pico a los 10-19 años. Las mujeres tienen mayor probabilidad de apendicectomía, debido a otras afecciones ginecológicas. El acceso a la apendicectomía disminuye la mortalidad; en estos pacientes, el 16 % fue laparoscópica, lo que sugiere que se necesita más entrenamiento y acceso a esta técnica. Este estudio aporta a la comprensión de la epidemiología de la apendicitis y apendicectomías en Colombia.

Introduction. Acute appendicitis is a common condition, with a peak incidence between 10 and 20 years of age. Surgery is the preferred treatment and laparotomy appendectomy remains the standard, although the laparoscopic approach has shown fewer complications. The objective of this article was to characterize both the disease and the surgical treatment in Colombia, using data from official databases. Methods. The Integrated Information System for Social Protection (SISPRO) database of the Ministry of Health was accessed in February 2023. Data with diagnosis of apendicitis and with appendectomy between 2017 and 2021 were collected. Analysis was done by age, gender, and geographic location. Results. Between 2017 and 2021, 345,618 cases of appendicitis were diagnosed (51.8% females), with peak incidence at 15-20 years of age. A total of 248,133 appendectomies were performed, 16.7% by laparoscopy. The hospitals with most reported procedures were located in Bogotá, Yopal, Popayán, and Florencia. Mortality was 0.56% in men and 0.51% in women. Conclusion. Appendicitis is common, peaking at ages 10-19. Women are more likely undergo appendectomy due to other gynecological conditions. Access to appendectomy improves mortality. In these patients, 16% were laparoscopic, suggesting that more training and access to this technique is needed. This study contributes to the understanding of the epidemiology of appendicitis and appendectomies in Colombia.

Cáncer incidental de vesícula: incidencia y factores asociados en pacientes de una institución de la ciudad de Medellín / Incidental gallbladder cancer: Incidence and associated factors in patients from an institution in the city of Medellín

Introducción. El cáncer de vesícula biliar es una de las neoplasias más frecuentes de la vía biliar y la mayoría de los casos se diagnostican de forma incidental o en estadios avanzados. En Colombia existen pocas publicaciones acerca de la prevalencia y características clínicas de pacientes con cáncer insospechado de vesícula biliar. El objetivo de este trabajo fue actualizar la información existente. Métodos. Estudio de tipo transversal basado en registros médicos. Como variable de resultado se definió el hallazgo incidental de patología maligna reportado por un patólogo y el subtipo histológico. Se midieron variables demográficas, clínicas y quirúrgicas. Se calcularon OR con sus respectivos intervalos de confianza (IC95%). Resultados. De los 2630 casos analizados, en cuatro se hizo diagnóstico de cáncer incidental de vesícula, con una prevalencia del 0,15 %. Se encontraron como características asociadas al cáncer incidental de vesícula, la edad, el antecedente de cáncer y la presencia de pólipos. Conclusiones. Esta es una patología poco frecuente en la población evaluada, lo que permite afirmar que no es necesario realizar estudios prequirúrgicos más amplios de forma rutinaria, a menos que el paciente presente alguno de los factores asociados.

Introduction. Gallbladder cancer is one of the most common neoplasms of the bile duct and most cases are diagnosed incidentally or in advanced stages. In Colombia, there are few publications about the prevalence and clinical characteristics of patients with unsuspected gallbladder cancer. The objective of this work was to update the existing information. Methods. Cross-sectional study based on medical records. The incidental finding of malignant pathology reported and the histological subtype were defined as the outcome variable. Demographic, clinical and surgical variables were measured. ORs were calculated with their respective 95% CI. Results. Of the 2630 cases analyzed, four were diagnosed with incidental gallbladder cancer, with a prevalence of 0.15%. Characteristics associated with incidental gallbladder cancer were age, history of cancer and the presence of polyps. Conclusions. This is a rare pathology in the population evaluated, which allows us to recommend that it is not necessary to routinely perform more extensive presurgical studies, unless the patient presents any of the associated factors.

Distribución de genotipos de virus papiloma humano de alto riesgo en mujeres y hombres atendidos en una red asistencial privada en la Región Metropolitana, Chile / Distribution of high-risk human papillomavirus genotypes in women and men attended in a private healthcare network in the Metropolitan Region, Chile

Introducción: La infección persistente por genotipos de virus papiloma humano de alto riesgo (VPH-AR) es la principal causa del cáncer cérvico-uterino en todo el mundo. Los genotipos 16 y 18 están asociados a la progresión hacia el cáncer de cuello uterino; sin embargo, otros genotipos también presentan alto riesgo oncogénico. Existe escasa evidencia respecto a la distribución de genotipos VPH-AR en la población nacional, siendo un tema que debiese ser abordado en el contexto de un creciente aumento de la inmigración e implementación del programa de inmunización en Chile desde 2015. Objetivo: Dar a conocer la distribución de genotipos de VPH-AR detectados en pacientes de ambos sexos, atendidos en la red de atención privada de Clínica Dávila de Santiago, entre los años 2014 y 2021. Metodología: Se estudiaron muestras genitales y anales provenientes de 3.642 pacientes, incluyendo ambos sexos. La genotipificación fue realizada mediante reacción de la polimerasa en cadena (RPC) en tiempo real (HPV AnyplexTM II HPV28 detection, Seegene, Korea. Resultados: La distribución global de genotipos en mujeres (porcentaje) fue: 16 (14,34%) - 31 (6,20%) - 39 (5,94%) - 58 (5,94%) - 51 (5,68%) - 53 (5,64%) - 52 (5,30%) - 56 (5,27%) - 68 (5,19%) - 66 (4,97% - 18 (3,36%) - 59 (3,29%) - 73 (2,80%) - 35 (2,54%) - 45 (2,13%) - 33 (1,53%) - 82 (1,38%) - 26 (0,49%) y 69 (0,41%). En hombres fue: 16 (8,52%) - 58 (4,39%) - 51 (8,44%) - 26 (0,42%) - 18 (3,21%) - 52 (4,47%) - 39 (5,40%) - 53 (4,56%) - 33 (1,69%) - 35 (2,03%), 73 (2,19%) - 69 (0,59%) - 45 (2,11%) - 59 (4,22%) - 68 (3,04%) - 66 (5,06%) - 31 (4,64%) - 56 (4,81%) y 82 (1,10%). Conclusiones: La distribución de los genotipos de VPH fue concordante con estudios previos nacionales. Se observó una tendencia a la reducción del genotipo 16 en el tiempo, lo cual podría relacionarse a la vacunación, implementada en los últimos años en Chile. Destaca que otros genotipos de VPH-AR tuvieron una alta frecuencia en la población estudiada por lo que sería recomendable evaluar la pesquisa ampliada de genotipos de VPH-AR para valorar el riesgo oncogénico, con fines diagnósticos y terapéuticos.

Background: Persistent infection by high-risk human papillomavirus (HR-HPV) genotypes is the main cause of cervical cancer worldwide. Genotypes 16 and 18 are associated with progression to cervical cancer, however other genotypes also present high oncogenic risk. There is little evidence regarding the distribution of HR-HPV genotypes in the national population, being an issue that should be addressed in the context of a growing increase in immigration and implementation of the immunization program in Chile since 2015. Aim: To show the distribution of HR-HPV genotypes detected in women and men, attended at the private care network of Clinica Davila, Santiago City, between 2014 and 2021. Methods: Genital and anal samples from 3,642 patients were studied, including both sexes. Genotyping was performed by real-time polymerase chain reaction (PCR) (HPV AnyplexTM II HPV28 detection, Seegene, Korea). Results: The global distribution of genotypes in women (percentage) was: 16 (14.34%) - 31 (6.20%) - 39 (5.94%) - 58 (5.94%) - 51 (5.68%) - 53 (5.64%) - 52 (5.30%) - 56 (5.27%) - 68 (5.19%) - 66 (4.97%) - 18 (3.36%) - 59 (3.29%) - 73 (2.80%) - 35 (2.54%) - 45 (2.13%) - 33 (1.53%) - 82 (1.38%) - 26 (0.49%) and 69 (0.41%). In men was: 16 (8.52%) - 58 (4.39%) - 51 (8.44%) - 26 (0.42%) - 18 (3.21%) - 52 (4.47%) - 39 (5.40%) - 53 (4.56%), 33 (1.69%) - 35 (2.03%) - 73 (2.19%) - 69 (0.59%) - 45 (2.11%) - 59 (4.22%) - 68 (3.04%) - 66 (5.06%) - 31 (4.64%) - 56 (4.81%) and 82 (1.10%). Conclusions: The distribution of HPV genotypes was consistent with previous national studies. A tendency to reduce genotype 16 over the years was observed, which could be related to the vaccination, implemented in recent years in Chile. It is remarkable that other HR-HPV genotypes had a high frequency in the population studied, so it would be advisable to evaluate an expanded screening for HR-HPV genotypes to assess the oncogenic risk, for diagnostic and therapeutic purposes.

Objetivo: avaliar a prevalência de anomalias dentárias (AD) e outros achados orais em radiografias panorâmicas de pacientes com fissuras labiopalatais (FLP) nascidos no Nordeste brasileiro. Métodos: a amostra foi composta por 69 pacientes com fissuras labiopalatais unilateral (FLPu) (n = 51) e bilateral (FLPb) (n = 18), não sindrômicos, de ambos os sexos, idade de 6 a 17 anos, nascidos no Nordeste brasileiro. Foram analisados prontuários e radiografias panorâmicas de pacientes atendidos de janeiro/2020 a julho/2022. Os dados categóricos foram expressos em forma de frequência absoluta e percentual e comparados por teste exato de Fisher ou qui-quadrado de Pearson (SPSS, p < 0,05). Resultados: entre os achados orais, destacaram-se as anomalias de número e as ausências dentárias por trauma, cárie ou doença periodontal. As AD foram identificadas em 34 pacientes (49,3%). As anomalias de número apresentaram maior prevalência, com diferença estatística significativa para pacientes FLPb do sexo masculino (p = 0,047). A agenesia foi a AD mais frequente (n = 24; 34,8%). As ausências dentárias por trauma, cárie ou doença periodontal foram observadas em 44 pacientes (n = 63,8%), com uma diferença estatística significativa entre os grupos FLPu e FLPb (p = 0,018). Conclusões: as AD e as ausências dentárias por trauma, cárie ou doença periodontal apresentaram uma alta prevalência entre pacientes brasileiros com FLP e devem ser consideradas durante o planejamento ortodôntico-cirúrgico desses indivíduos.

Aim: this study aimed to assess the prevalence of dental anomalies (DA) and other oral findings in panoramic radiographs of patients with cleft lip and palate (CLP) born in the Northeast region of Brazil. Methods: the sample consisted of 69 patients with unilateral cleft lip and palate (UCLP) (n = 51) and bilateral cleft lip and palate (BCLP) (n = 18), non-syndromic, of both genders, aged 6 to 17 years, born in the Brazilian Northeast. Patient records and panoramic radiographs from those treated between January 2020 and July 2022 were analyzed. Categorical data were expressed as absolute frequency and percentage and compared using Fisher's exact test or Pearson's chi-square test (SPSS, p < 0.05). Results: among oral findings, anomalies in number and tooth absences due to trauma, caries, or periodontal disease stood out. DAs were identified in 34 patients (49.3%). Anomalies in number showed higher prevalence, with a statistically significant difference for male BCLP patients (p = 0.047). Agenesis was the most frequent DA (n = 24; 34.8%). Tooth absences due to trauma, caries, or periodontal disease were observed in 44 patients (63.8%), with a statistically significant difference between the UCLP and BCLP groups (p = 0.018). Conclusions: DAs and tooth absences due to trauma, caries, or periodontal disease showed a high prevalence among Brazilian patients with CLP and should be considered during the orthodontic-surgical planning for these individuals.

Pain Patterns of the Temporomandibular Joint Dysfunction and Implications of Stress-Related Behaviors: A Pilot Study / Patrones de Dolor de la Disfunción de la Articulación Temporomandibular e Implicaciones de los Comportamientos Relacionados con el Estrés: Un Estudio Piloto

SUMMARY: Temporomandibular joint dysfunction interferes with the quality of life and activities of daily living among patients. The symptoms of temporomandibular dysfunction, including pain and clicking and popping sounds, are worsened during stressful events, and patients report increased pain around the temporomandibular joint. Stress-related behaviors, such as teeth clenching and teeth grinding, are commonly reported as increasing during stress. The prevalence of temporomandibular dysfunction and stress-related behaviors is reported differently in the literature. Stress in higher education is common. The purpose of this pilot study was to investigate the prevalence of temporomandibular joint dysfunction and stress-related behaviors among staff members at a local University. The study also sought to explore pain patterns described by people experiencing temporomandibular joint dysfunction and the relationship between stress-related behaviors and pain symptoms experienced. Further, the impact of stress on symptoms experienced by people with temporomandibular dysfunction was investigated in this pilot study.

La disfunción de la articulación temporomandibular interfiere con la calidad de vida y las actividades de la vida diaria entre los pacientes. Los síntomas de la disfunción temporomandibular, incluidos el dolor y los chasquidos, empeoran durante los eventos estresantes, y los pacientes informan un aumento del dolor alrededor de la articulación temporomandibular. Los comportamientos relacionados con el estrés, como apretar y rechinar los dientes, suelen aumentar durante el estrés. La prevalencia de la disfunción temporomandibular y los comportamientos relacionados con el estrés se informa de manera diferente en la literatura. El estrés en la educación superior es común. El propósito de este estudio piloto fue investigar la prevalencia de la disfunción de la articulación temporomandibular y los comportamientos relacionados con el estrés entre los miembros del personal de una universidad local. El objetivo del estudio además fue explorar los patrones de dolor descritos por personas que experimentan disfunción de la articulación temporomandibular y la relación entre los comportamientos relacionados con el estrés y los síntomas de dolor experimentados. Además, en este estudio piloto se investigó el impacto del estrés en los síntomas que experimentan las personas con disfunción temporomandibular.

A systematic review of epidemiologic studies on scabies in the Philippines

Background and Objective@#Scabies is the second most common cause of disability due to skin disease in the Philippines. However, there were no cited studies in Global Burden of Disease 2019 and the disability-adjusted life years (DALY) computations were most likely based on statistical modelling. The Philippine Department of Health has embarked on a program to estimate the disease burden of priority diseases in the country, which include scabies. The last nationwide prevalence survey was 23 years ago. This systematic review aimed to estimate the prevalence or incidence of scabies in the Philippines. @*Methods@#We searched PubMed, Scopus, Herdin, and Philippine Health Research Registry (search date October 2022) for studies on prevalence/incidence (including systematic reviews, cross-sectional studies, cohort studies, case series, registry or census studies) of patients diagnosed with scabies in the Philippines. We excluded narrative reviews, commentaries, and conference proceedings or abstracts. Two reviewers independently screened titles and abstracts, assessed full text reports for eligibility, appraised the quality of included studies, and collected data using a pretested data extraction form. We did not pool studies due to clinical heterogeneity but plotted the individual studies in a forest plot with prevalence estimates and confidence intervals. We reported the median and interquartile range for entire group or relevant subgroups (age, setting) of studies. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to assess the certainty of evidence.@*Results@#We included nine studies (N=79,065). Most were clinic-based prevalence studies, retrospective chart reviews, conducted in dermatology outpatient clinics, Metro Manila area, and on pediatric populations. Prevalence of scabies was moderate (i.e., between 2 and 10%), ranging from 2.75% (national prevalence survey) to 6.8% (communitybased review), to high (> 10%) among pediatric patients in clinic-based retrospective chart reviews (29 to 36%) and institution-based surveys (39.0% to 45%), and a tertiary government university training hospital dermatology clinic (22.9%). The most affected age group was from 0 to 14 y/o, while males tended to have a higher prevalence than females. The cooler month of January had higher prevalence than the hotter month of June in one study. @*Conclusion@#Scabies is common in the Philippines, especially among children and elderly in institutional settings, and during the month of January. There is a need to do a national prevalence survey to identify high-risk areas and to monitor the prevalence of scabies, especially in crowded settings and vulnerable populations. This information can be used for estimating the burden of disease for scabies and guide appropriate health resource allocation.

Prevalence of Anemia in Patients with Diabetes Mellitus: A Systematic Review and Meta-Analysis / 生物医学与环境科学（英文）

OBJECTIVE@#Anemia is a common public health concern in patients with type 2 diabetes worldwide. This study aimed to identify the prevalence of anemia among patients with diabetes.@*METHODS@#Electronic databases, including PubMed, Scopus, Web of Sciences, and Google Scholar, were searched systematically for studies published between 2010 and 2021. After removing duplicates and inappropriate reports, the remaining manuscripts were reviewed and appraised using theNewcastle-Ottawa Scale (NOS) tool. A random-effects model was used to calculate the pooled estimates of the extracted data using Stata version 17. Heterogeneity of the studies was assessed using the Q statistic.@*RESULTS@#A total of 51 articles containing information on 26,485 patients with diabetes were included in this study. The articles were mainly from Asia (58.82%) and Africa (35.29%). The overall prevalence of anemia was 35.45% (95% CI: 30.30-40.76), with no evidence of heterogeneity by sex. Among the two continents with the highest number of studies, the prevalence of anemia in patients with diabetes was significantly higher in Asia [40.02; 95% CI: 32.72-47.54] compared to Africa [28.46; 95% CI: 21.90-35.50] ( P for heterogeneity = 0.029). Moreover, there has been an increasing trend in the prevalence of anemia in patients with diabetes over time, from [15.28; 95% CI: 9.83-22.21] in 2012 to [40.70; 95% CI: 10.21-75.93] in 2022.@*CONCLUSION@#Globally, approximately 4 in 10 patients with diabetes suffer from anemia. Therefore, routine anemia screening and control programs every 3 months might be useful in improving the quality of life of these patients.

Seasonal variations of the prevalence of metabolic syndrome and its markers using big-data of health check-ups

BACKGROUND@#It is crucial to understand the seasonal variation of Metabolic Syndrome (MetS) for the detection and management of MetS. Previous studies have demonstrated the seasonal variations in MetS prevalence and its markers, but their methods are not robust. To clarify the concrete seasonal variations in the MetS prevalence and its markers, we utilized a powerful method called Seasonal Trend Decomposition Procedure based on LOESS (STL) and a big dataset of health checkups.@*METHODS@#A total of 1,819,214 records of health checkups (759,839 records for men and 1,059,375 records for women) between April 2012 and December 2017 were included in this study. We examined the seasonal variations in the MetS prevalence and its markers using 5 years and 9 months health checkup data and STL analysis. MetS markers consisted of waist circumference (WC), systolic blood pressure (SBP), diastolic blood pressure (DBP), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), fasting plasma glucose (FPG).@*RESULTS@#We found that the MetS prevalence was high in winter and somewhat high in August. Among men, MetS prevalence was 2.64 ± 0.42 (mean ± SD) % higher in the highest month (January) than in the lowest month (June). Among women, MetS prevalence was 0.53 ± 0.24% higher in the highest month (January) than in the lowest month (June). Additionally, SBP, DBP, and HDL-C exhibited simple variations, being higher in winter and lower in summer, while WC, TG, and FPG displayed more complex variations.@*CONCLUSIONS@#This finding, complex seasonal variations of MetS prevalence, WC, TG, and FPG, could not be derived from previous studies using just the mean values in spring, summer, autumn and winter or the cosinor analysis. More attention should be paid to factors affecting seasonal variations of central obesity, dyslipidemia and insulin resistance.

Prevalence of parasites in selected captive bird species / Prevalência de parasitas em espécies de pássaros em cativeiro selecionados

Abstract Blood and fecal samples of chukar partridge (Alectoris chukar), albino pheasant (Phasianus colchicus), silver pheasant (Lophura nycthemera), rose-ringed parakeet (Psittacula krameri) and turkeys (Meleagris gallopavo) were analyzed to check parasitic prevalence. To record parasites these five avian species were placed kept in separate cages at Avian Conservation and Research Center, Department of Wildlife an Ecology, University of Veterinary and Animal Sciences, Lahore, Pakistan. 100 fecal and 100 blood samples for each bird species were inspected to analyze internal parasites. During present study, 17 species of endoparasites 14 from fecal samples and three from blood were examined. Two species of ectoparasites i.e. mite Dermanyssus gallinae 42% and fowl ticks Args persicus 41%were studied. Blood parasites included Plasmodium juxtanucleare 50%, Leucoctoyzoon simond having parasitic prevalence 40%, and Aegyptinella pullorum having parasitic prevalence of 40%. Parasitic species recorded from fecal samples included 6 species of nematodes viz. Allodpa suctoria 2%. Syngamus trachea with parasitic prevalence of 60%, Capillaria annulata 37.5%, Ascardia galli 24%, Capillaria anatis 40% and Heterakis gallinarum 28.3%. Similarly, two species of trematodes viz. Prosthogonimus ovatus having parasitic prevalence of 50% and Prosthogonimus macrorchis 21% were also documented from fecal avian samples . Single cestode species Raillietina echinobothrida having parasitic prevalence of 72% and 3 protozoan species i.e. Eimeria maxima having parasitic prevalence of 21%, Giardia lamblia 41% and Histomonas meleagridis 18% were documented during corpological analysis. In our recommendation, proper sanitation, medication and vaccination of bird's enclousres are suggested to avoid parasites.

RESUMO Amostras de sangue e fezes de perdiz chukar (Alectoris chukar), faisão-albino (Phasianus colchicus), faisão-prateado (Lophura nycthemera), periquito-de-rosa (Psittacula krameri) e perus (Meleagris gallopavo) foram analisadas para verificar a prevalência de parasitas.

Prevalência e fatores associados ao uso de cigarro eletrônico por estudantes universitários / Prevalence and factors associated with electronic cigarette use by university students / Prevalencia y factores asociados al uso de cigarrillos electrónicos por estudiantes universitarios

Este estudo objetivou estimar a prevalência do uso do cigarro eletrônico e a associação com fatores preditores. Trata-se de um estudo transversal, analítico, com amostra probabilística de universitários matriculados em um Centro Universitário de Montes Claros, Minas Gerais, Brasil no segundo semestre de 2022. A variável dependente referiu-se ao uso do cigarro eletrônico. As variáveis independentes referiram a fatores sociodemográficas, laborais e comportamentais. A associação entre as variáveis investigadas e a prevalência do uso do CE foi verificada pela análise bivariada e a regressão de Poisson. Foram entrevistados 730 universitários, com a média de idade de anos 22,56 (±6,25). Destes, 21,8 % faziam o uso cigarro eletrônico e após a análise multivariada manteve-se associado ao desfecho não ter companheiro (RP= 3,31; IC95% 1,04-10,48), morar com amigos/sozinho (RP=1,53; IC95% 1,07-2,18), ter histórico de usuários de cigarro eletrônico na residência (RP= 1,76; IC95%: 1,17- 1,89), consumir bebida alcoólica (RP= 3,07; IC95%: 1,72-5,49) e não praticar atividade física (RP= 3,37; IC95% 2,35-4,83). Conhecer sobre o cigarro eletrônico foi fator protetor (RP= 0,31 IC95% 0,20-0,46). Registrou-se elevada prevalência do uso do cigarro eletrônico, e manteve associados a fatores sociodemográficos e comportamentais. Esses achados chamam a atenção para a necessidade de novas medidas regulatórias, a fim de reduzir o uso desse dispositivo.

This study aimed to estimate the prevalence of e-cigarette use and the association with predictors. This is a cross-sectional, analytical study with a probabilistic sample of university students enrolled in a University Center of Montes Claros, Minas Gerais, Brazil in the second half of 2022. The dependent variable referred to the use of electronic cigarettes. The independent variables referred to sociodemographic, labor and behavioral factors. The association between the variables investigated and the prevalence of EC use was verified by bivariate analysis and Poisson regression. A total of 730 university students were interviewed, with a mean age of 22.56 (±6.25). Of these, 21.8% used electronic cigarettes and after multivariate analysis, it remained associated with the outcome of not having a partner (PR= 3.31; CI95% 1.04-10.48), living with friends/alone (PR=1.53; CI95% 1.07-2.18), having a history of e-cigarette users in the residence (PR= 1.76; CI95%: 1.17- 1.89), alcohol consumption (PR= 3.07; CI95%: 1.72-5.49) and not practicing physical activity (PR= 3.37; IC95% 2.35-4.83). Knowing about electronic cigarettes was a protective factor (PR= 0.31 CI95% 0.20-0.46). There was a high prevalence of e-cigarette use, and it was associated with sociodemographic and behavioral factors. These findings draw attention to the need for new regulatory measures in order to reduce the use of this device.

La asociación entre las variables investigadas y la prevalencia de uso de CE fue verificada por análisis bivariado y regresión de Poisson. Fueron entrevistados 730 estudiantes universitarios, con una edad promedio de 22,56 (±6,25). De estos, 21,8% utilizaron cigarrillos electrónicos y después del análisis multivariado, se mantuvo asociado con el resultado de no tener pareja (RP= 3,31; IC95% 1,04-10,48), vivir con amigos/solo (RP=1,53; IC95% 1,07-2,18), con antecedentes de usuarios de cigarrillos electrónicos en la residencia (RP= 1,76; IC95%: 1,17- 1,89), consumo de alcohol (RP= 3,07; IC95%: 1,72-5,49) y no practicar actividad física (RP= 3,37; IC95% 2,35-4,83). El conocimiento de los cigarrillos electrónicos fue un factor protector (RP= 0,31 IC95% 0,20-0,46). Hubo una alta prevalencia de uso de cigarrillos electrónicos, y se asoció con factores sociodemográficos y de comportamiento. Estos hallazgos llaman la atención sobre la necesidad de nuevas medidas regulatorias para reducir el uso de este dispositivo.
