RESUMO Objetivo: Descrever casos de lesão renal aguda (LRA) em crianças diagnosticadas com COVID-19, associando fatores de risco, aspectos clínicos e evolução dos casos. Métodos: Estudo retrospectivo, realizado em hospital pediátrico entre março de 2020 e setembro de 2021, com pacientes com COVID-19 diagnosticados com LRA, que examinou informações presentes em prontuários como comorbidades, idade, sexo e uso de medicações nefrotóxicas. Resultados: Foram estudados 40 casos, sendo o sexo masculino significativamente mais acometido (62,5%; p=0,025). A LRA foi uma complicação grave da infecção por COVID-19, com 100% da amostra necessitando de internação na Unidade de Terapia Intensiva e 22,5% indo a óbito. As comorbidades mais prevalentes analisadas neste estudo foram epilepsia, paralisia cerebral e cardiopatia. A maioria dos pacientes foi classificada pelos critérios Kidney Disease: Improving Global Outcomes (KDIGO) como KDIGO 1 (42,5%) e necessitou de intubação orotraqueal (67,5%). A frequência de uso de medicamentos nefrotóxicos e necessidade de diálise foi baixa, com percentuais de 35 e 17,5%, respectivamente. Entre as crianças que faleceram, 70,4% apresentavam alguma comorbidade e 88,8% receberam ventilação invasiva. Conclusões: A LRA em crianças com infecção por COVID-19 está associada a quadros graves, apesar de a maior parte dos pacientes ter recebido alta hospitalar.

ABSTRACT Objective: To describe cases of acute kidney injury (AKI) in children diagnosed with COVID-19, associated risk factors, clinical aspects and outcome of cases. Methods: Retrospective study, carried out in a pediatric hospital between March 2020 and September 2021, with patients with COVID-19 who were diagnosed with AKI, studying information present in medical records such as comorbidities, age, gender and use of nephrotoxic medications. Results: We studied 40 cases, and male individuals were significantly more affected (62.5%; p=0.025). AKI was a severe complication of COVID-19 infection, with 100% of the sample requiring admission to the Intensive Care Unit and 22.5% dying. The most prevalent comorbidities analyzed in this study were epilepsy, cerebral palsy and heart disease. Most patients were classified according to Kidney Disease: Improving Global Outcomes (KDIGO) criteria as KDIGO 1 (42.5%), and required orotracheal intubation (67.5%). The frequency of use of nephrotoxic medications and need for dialysis was low, with percentages of 35 and 17.5%, respectively. Among the children who died, 70.4% had some comorbidity and 88.8% received invasive ventilation. Conclusions: AKI in children with COVID-19 infection is associated with severe conditions. Despite the severity, most patients were discharged alive from the hospital.

Abstract: The aim of this work is to put forward a methodology to evaluate the oscillatory stability of a power electric system (PES) analyzing the low-frequency oscillatory modes (LFOM) through the processing of synchrophasor measurements Phasor Measurement Units (PMU) of ambient data. The proposed methodology, based on spectral and pseudo-energy analyses and on parametric methods of Canonical Correlation Analysis and Yule-Walker, estimates the LFOM, whose frequency and damping characteristics provide critical information to PES operators to carry out preventive or emergency control actions. The proposed methodology was applied to synthetic measurements for its tuning and to characterize its range and accuracy, and to PMU records of the Ecuadorian power transmission system, successfully identifying the 0.4 Hz inter-area mode of the Ecuador-Colombia interconnection. The contributions of this work are aimed at evaluating the oscillatory stability of the PES through automatic computational tool that processes PMU signals of ambient type data.

Resumen: El objetivo de este trabajo es presentar una metodología para evaluar la estabilidad oscilatoria de un sistema eléctrico de potencia (SEP) mediante el análisis de los modos oscilatorios de baja frecuencia (MOBF) a través del procesamiento de mediciones sincrofasoriales (Phasor Measurement Units PMU) de datos tipo ambiente. La metodología propuesta, basada en los análisis espectral y de pseudoenergía y en los métodos paramétricos de Análisis de Correlación Canónica y de Yule - Walker, estima los MOBF, cuyas características de frecuencia y amortiguamiento brindan información crítica a los operadores del SEP para adoptar acciones de control preventivo o de emergencia. La metodología propuesta fue aplicada a mediciones sintéticas para su sintonización y caracterizar su alcance y precisión, y a registros PMU del sistema de transmisión de energía de Ecuador logrando identificar satisfactoriamente el modo interárea de 0,4 Hz propio de la interconexión Ecuador-Colombia. Las contribuciones de este trabajo están encaminadas a evaluar la estabilidad oscilatoria de los SEP a través de una herramienta computacional automática que procese señales PMU de datos tipo ambiente.

Resumen Objetivo: caracterizar sociodemográficamente pacientes que padecen trastornos del estado de ánimo en Institución Prestadora de Servicios (IPS) de salud mental en Montería, departamento de Córdoba - Colombia, correlacionando este diagnóstico con variables de interés. Materiales y métodos: estudio descriptivo, retrospectivo-longitudinal, que correlacionó variables sociodemográficas con trastornos del estado de ánimo en 729 pacientes hospitalizados en una IPS, procedentes de municipios del departamento de Córdoba, en el período 2012- 2021-I. Resultados: hombres con edad promedio de 23 años presentaron mayor frecuencia de trastornos del estado de ánimo n=689 que mujeres n= 40; en su mayoría procedentes de municipios como Montería, Puerto Libertador, Valencia, Tierralta y Canalete; siendo Montería el municipio con mayor población y menor prevalencia; factores como lugar de procedencia, falta de apoyo familiar y estrés fueron quienes incidieron en recaídas, registrándose disminución en hospitalización de estos pacientes durante la pandemia COVID-19. Conclusión: existe correlación entre variables sociodemográficas como lugar de procedencia del departamento de Córdoba, falta de apoyo familiar y estrés como determinantes para la ocurrencia del diagnóstico de trastornos del estado de ánimo, en pacientes que proceden de municipios caracterizados por niveles de violencia alto y medio, baja cobertura educativa y pobreza multifuncional en población vulnerable.

ABSTRACT Objective : To sociodemographically characterize patients with Mood Disorders in a Mental Health Institution in Montería, Córdoba - Colombia, and correlate this diagnosis with variables of interest. Materials and Methods: This descriptive, retrospective-longitudinal study correlated sociodemographic variables with Mood Disorders in 729 hospitalized patients in an Institution of Mental Health, originating from municipalities in the department of Córdoba, during the period 2012-2021. Results: Men with an average age of 23 years presented a higher frequency of Mood Disorders (n=689) compared to women (n=40). The majority of patients originated from municipalities such as Montería, Puerto Libertador, Valencia, Tierralta, and Canalete. Montería, being the municipality with the largest population, showed a lower prevalence. Factors such as place of origin, lack of family support, and stress influenced relapses, with a decrease in hospitalizations of these patients during the COVID-19 pandemic. Conclusion: There is a correlation between sociodemographic variables such as the place of origin in the department of Córdoba, lack of family support, and stress as determinants for the occurrence of Mood Disorders diagnosis in patients from municipalities characterized by high and medium levels of violence, low educational coverage, and multifunctional poverty in vulnerable populations.

Abstract Introduction The limited access to temporal fine structure (TFS) cues is a reason for reduced speech-in-noise recognition in cochlear implant (CI) users. The CI signal processing schemes like electroacoustic stimulation (EAS) and fine structure processing (FSP) encode TFS in the low frequency whereas theoretical strategies such as frequency amplitude modulation encoder (FAME) encode TFS in all the bands. Objective The present study compared the effect of simulated CI signal processing schemes that either encode no TFS, TFS information in all bands, or TFS only in low-frequency bands on concurrent vowel identification (CVI) and Zebra speech perception (ZSP). Methods Temporal fine structure information was systematically manipulated using a 30-band sine-wave (SV) vocoder. The TFS was either absent (SV) or presented in all the bands as frequency modulations simulating the FAME algorithm or only in bands below 525 Hz to simulate EAS. Concurrent vowel identification and ZSP were measured under each condition in 15 adults with normal hearing. Results The CVI scores did not differ between the 3 schemes (F (2, 28) = 0.62, p = 0.55, η2p = 0.04). The effect of encoding TFS was observed for ZSP (F (2, 28) = 5.73, p = 0.008, η2p = 0.29). Perception of Zebra speech was significantly better with EAS and FAME than with SV. There was no significant difference in ZSP scores obtained with EAS and FAME (p = 1.00) Conclusion For ZSP, the TFS cues from FAME and EAS resulted in equivalent improvements in performance compared to the SV scheme. The presence or absence of TFS did not affect the CVI scores. (TFS speechinnoise noise (CI users (EAS FSP (FSP (FAME lowfrequency (CVI ZSP. .

Abstract This paper involves the analysis of the quality of anthropometric data on children under five years of age in two information systems in the State of São Paulo. The sample included 2,117,108 children from the Food and Nutrition Surveillance System (SISVAN), and 748,551 from the State Milk Project (VIVALEITE). Initially, we evaluated the frequency of missing values and others outside the equipment spectrum and calculated the digit-to-weight preference index. After calculating height-for-age (HAZ), weight-for-age (WAZ), and body mass index-for-age (BAZ), we flagged the biologically implausible values (BIV) and calculated the standard deviation (SD). For each municipality, we calculated the mean and the SD of HAZ, WAZ, and BAZ; and plotted the SD values as a function of the mean. The digit-to-weight preference index was greater among children aged between 24 and 59 months in SISVAN. The frequency of BIV for HAZ (SISVAN 2.56%; VIVALEITE 0.98%) was higher than for WAZ (SISVAN 2.10%; VIVALEITE 0.18%). For HAZ, variations among municipalities were more pronounced in VIVALEITE than in SISVAN. The height variable presents low reliability in both systems. The weight variable reveals satisfactory quality in VIVALEITE and unsatisfactory quality in SISVAN. Paulo 2117108 2 117 108 2,117,10 SISVAN, SISVAN , (SISVAN) 748551 748 551 748,55 VIVALEITE. .

Resumo O objetivo foi analisar a qualidade dos dados antropométricos de crianças menores de cinco anos em dois sistemas de informação no estado de São Paulo. A amostra compreendeu 2.117.108 crianças do Sistema de Vigilância Alimentar e Nutricional (Sisvan) e 748.551 do Projeto Estadual do Leite (Vivaleite). Inicialmente, avaliamos a frequência de valores faltantes e fora do espectro do equipamento, e calculamos o índice de preferência de dígito para peso. Após calcular os índices de altura para idade (A-I), peso para idade (P-I) e índice de massa corporal para idade (IMC-I), identificamos os valores biologicamente implausíveis (VBI) e calculamos o desvio-padrão (DP). Para cada município, calculamos a média e o DP de A-I, P-I e IMC-I; e plotamos os valores de DP em função da média. A preferência de dígito no peso foi maior em crianças de 24 a 59 meses no Sisvan. A frequência de VBI para A-I (SISVAN 2,56%; Vivaleite 0,98%) foi maior do que para P-I (Sisvan 2,10%; Vivaleite 0,18%). Para o índice A-I as variações entre os municípios foram mais acentuadas no Vivaleite do que no Sisvan. A variável altura apresentou baixa confiabilidade nos dois sistemas. A variável peso apresentou qualidade satisfatória no Vivaleite e insatisfatória no Sisvan. Paulo 2117108 2 117 108 2.117.10 Sisvan 748551 748 551 748.55 Vivaleite. .

Abstract The presence of the rabies virus and antibodyes in bats from the Americas is mainly associated with hematophagous species; however, this virus has also been detected with low frequency in bats with other feeding habits. The same thing happens in Mexico, although there is no updated information on the species that have been infected by this virus. Due to the public health implications of the subject, in this study we explore how the presence of the rabies virus is related to eating habits, the family to which they belong, the size of the distribution area and the type of refuge used by bats. Based on a review of the scientific literature published from 1954 to 2015, seven families, 24 genera, and 40 species of non-hematophagous bats that have been detected with rabies virus in Mexico. Most are insectivorous (63%) and belong to the Phyllostomidae and Vespertilionidae families (68%). The presence of rabies is positively and significantly related to the number of species per family (r = 0.9, p < 0.005) and type of feeding habit (r = 0.97, p < 0.002) but is not related to the size of its distribution area (r = 0.2, p = 0.2). Cases of rabies in non-hematophagous species in Mexico are rare, and do not represent a risk of transmission to humans.

Resumen La presencia de anticuerpos del virus de la rabia en murciélagos de América se asocia principalmente con especies hematófagas, sin embargo, este virus también se ha detectado con baja frecuencia en murciélagos con otros hábitos alimenticios. En México sucede lo mismo, aunque no se cuenta con información actualizada de las especies que han sido contagiadas por este virus. Debido a las implicaciones de salud pública que involucra el tema, en este estudio exploramos cómo se relaciona la presencia de la rabia detectada con base en anticuerpos específicos y por la presencia del virus de la rabia en murciélagos no hematófagos, con el hábito alimenticio, la familia a la que pertenecen, el tamaño del área de distribución y el tipo de refugio. Con base en una revisión de la literatura científica publicada de 1954 a 2015, se registraron siete familias, 24 géneros y 40 especies de murciélagos no hematófagos con el virus de la rabia en México. La mayoría son de hábitos insectívoros (63%) y pertenecen a las familias Phyllostomidae y Vespertilionidae (68%). La presencia de rabia se relaciona positiva y significativamente con el número de especies por familia (r = 0.9, p < 0.005) y el tipo de hábito alimenticio (r = 0.97, p < 0.002) pero no se relaciona con el tamaño de su área de distribución (r = 0.2, p = 0.2). Los casos de rabia en especies no hematófagas en México son escasos, y no representan un riesgo de transmisión al humano.

ABSTRACT Background: To evaluate the 10-year functional outcomes (primary) and frequency and predictors of BPH surgical retreatment (secondary) after ThuLEP. Materials and Methods: A single-center retrospective analysis of consecutive patients undergoing ThuLEP between 2010 and 2013 was performed. Inclusion criteria were: age ≥ 40 years, prostate volume (PV) ≥ 80 mL, International Prostate Symptom Score (IPSS)-Total score ≥ 8 points. IPSS-Total score was the primary outcome, and BPH surgical retreatment rate was the secondary outcome. Paired t-test, McNemar test, and Wilcoxon signed-rank test were used to compare variables. Logistic regression analysis was performed to evaluate predictors of surgical retreatment. Results: A total of 410 patients with a mean ±SD age of 63.9 ± 9.7 years and a PV of 115.6 ± 28.6 mL were included. Mean ±SD follow-up was 108.2 ± 29.6 months. IPSS-Total score was significantly improved at 1 year compared to baseline (23.3 ± 4.7 vs. 10.3 ± 3.8; p<0.001). It was similar after 5 years (10.5 ± 3.6 vs. 10.7 ± 5.0; p=0.161), with a significant worsening at 10 years (10.3 ±4.8 vs. 13.8 ±4.5; p=0.042) but remaining statistically and clinically better than baseline (13.8 ±4.5 vs. 22.1 ±4.3; p<0.001). After 10 years, 21 (5.9%) patients had undergone BPH reoperation. Baseline PV (adjusted OR 1.27, 95% CI 1.09-1.41; p<0.001) and time from BPH surgery (adjusted OR 1.32, 95% CI 1.15-1.43; p<0.001) were predictors of BPH surgical retreatment. Conclusions: ThuLEP is associated with optimal functional outcomes and a low frequency of BPH surgical retreatment in the long-term. Baseline PV and time from surgery were predictors of BPH reoperation.

Abstract: Preterm infants, especially those of lower gestational age (GA), are at high risk of hospital readmission in the early years. Objective: To describe the frequency and characteristics of readmissions in preterm infants younger than 32 weeks of GA or weighing less than 1500 g (< 32w/< 1500 g) at 2 years post-discharge from neonatology. Patients and Method: Retrospective observational study of a cohort of newborns < 32w/< 1500 g discharged from a public health care center (2009-2017). The frequency, time of occurrence, risk factors, causes, and severity of hospital readmissions were analyzed. The respective perinatal characteristics and subsequent readmissions were described. The Ethics Committee approved the data collection protocol. Results: 989 newborns < 32w/< 1500 g were included; 410 (41.5%) were readmitted at least once before the age of 2 years, equivalent to 686 episodes (1.7/child); 129 children (31.4%) were admitted to the Pediatric Intensive Care Unit (PICU), with a mean length of stay of 7.7 days. The greatest risk for hospital readmission was during the first 6 months post-discharge. The main cause was respiratory (70%) and respiratory syncytial virus was the most frequent germ. The risk factors associated with readmission due to respiratory causes were bronchopulmonary dysplasia (BPD) (OR: 1.73; 95%CI: 1.26-2.37) and number of siblings (OR: 1.18; 95%CI: 1.04-1.33). Conclusions: Newborns < 32s/< 1500 g are at high risk of hospital readmission due to respiratory causes and PICU admission in the first months post-discharge; BPD and number of siblings were the main risk factors.

Resumen: Los prematuros, especialmente aquellos de menor edad gestacional (EG), presentan alto riesgo de rehospitalización en los primeros años. Objetivo: Describir la frecuencia y características de las rehospitalizaciones en prematuros menores de 32 semanas de EG o menores de 1500 g (< 32s/< 1500 g) a 2 años post alta de neonatología. Pacientes y Método: Estudio observacional retrospectivo de una cohorte de < 32 s/< 1500 g egresados de un centro asistencial público (2009-2017). Se investigó la frecuencia, momento de ocurrencia, factores de riesgo, causas y severidad de las rehospitalizaciones. Se describen las respectivas características perinatales y las subsecuentes rehospitalizaciones. El Comité de Ética aprobó el protocolo de recolección de datos. Resultados: Se incluyeron 989 < 32s/< 1500 g; 410 (41,5%) fueron rehospitalizados al menos 1 vez antes de los 2 años, equivalente a 686 episodios (1,7/niño); 129 niños (31,4%) ingresaron a la Unidad de Cuidados Intensivos Pediátricos (UCIP), con una estadía media de 7,7 días. Los momentos de mayor riesgo fueron los primeros 6 meses post alta. La principal causa fue respiratoria (70%) siendo el virus respiratorio sincicial el germen más frecuente. Los factores de riesgo asociados a rehospitalización de causa respiratoria fueron la displa- sia broncopulmonar (DBP) (OR = 1,73; IC95%: 1,26-2,37) y el número de hermanos (OR = 1,18; IC95%: 1,04-1,33). Conclusiones: Los < 32s/< 1500 g tienen alto riesgo de rehospitalización de causa respiratoria y de ingresar a UCIP en los primeros meses post alta, siendo la DBP y el número de hermanos los principales factores de riesgo.

Resumen En este trabajo se presentan los primeros resultados sobre el origen continental materno de las principales localidades de la provincia de Tierra del Fuego (TDF): Río Grande (RG) y Ushuaia (USH), mediante la tipificación de haplogrupos mitocondriales (Hg) de 333 participantes. La estimación de los Hg se realizó mediante PCR-APLP y secuenciación de la región HV1, evidenciando una significativa frecuencia de Hg maternos de origen americano a nivel provincial (64,9%). A nivel local, se observó una mayor proporción de linajes autóctonos en RG (75,1%) respecto de USH (57,5%). A partir de la información genealógica de los participantes, se evidenció que el origen geográfico más frecuente tanto de los participantes como de los ancestros, es la región Centro de Argentina. Las diferencias observadas entre dos localidades que distan a sólo 200 km, en una provincia de baja densidad demográfica, ponen en evidencia una vez más la importancia de conocer la información genealógica de los participantes, así como la historia fundacional y las actividades económicas de cada localidad que han motivado la llegada de migrantes, para una adecuada contextualización y comprensión de la actual composición genética de la provincia de TDF.

Abstract This paper presents the first results on the maternal continental origin of the main localities in the province of Tierra del Fuego (TDF): Río Grande (RG) and Ushuaia (USH), by typing of mitochondrial haplogroups (Hg) in 333 participants. The estimation of Hg was carried out using PCR-APLP and sequencing of the HV1 region, evidencing a significant frequency of maternal Hg of American origin at the provincial level (64.9%). At the local level, a higher proportion of autochthonous lineages was observed in RG (75.1%) compared to USH (57.5%). From the genealogical information of the participants, it was verified that the most frequent geographical origin of both participants and ancestors is the Central region of Argentina. The differences observed between the two localities, which are only 200 km away, in a province with low demographic density, once again highlight the importance of knowing the genealogical information of the participants, as well as the founding history and economic activities of each locality that have motivated the arrival of migrants, to achieve a better contextualization and understanding of the current genetic composition of the province of TDF.

Abstract The development of vaccinations has been game-changing in the ongoing effort to combat the COVID-19 pandemic. Until now, adverse effects are being reported at low frequency, including thrombocytopenia and myocarditis. Careful monitoring for any suspicious symptoms and signs following vaccination is necessary. We report a case of hemophagocytic lymphohistiocytosis (HLH) after mRNA COVID-19 vaccine in a 23-year-old female with ulcerative colitis. Diagnosis was made according to HLH-2004 criteria and the patient was treated with dexamethasone with response. Our report aimed to draw attention to the potential relation between COVID-19 vaccines and HLH and the necessity of continued surveillance, especially in at-risk populations such as those with underlying immune dysregulation.

Resumo O desenvolvimento de vacinas foi um ponto de viragem no combate contra a pandemia da COVID-19. Até ao momento, os efeitos adversos como a trombocitopenia e miocardite têm sido reportados com baixa frequência. A monitorização cuidadosa de qualquer sinal ou sintoma suspeitos é essencial. Reportamos um caso de linfohistiocitose hemofagocítica após vacinação contra a COVID-19 com uma vacina de mRNA, numa jovem de 23 anos com colite ulcerosa. O diagnóstico obedeceu os critérios HLH-2004 e a paciente foi tratada com dexametasona, com resposta. Pretendemos chamar à atenção para a potencial relação entre a vacinação para a COVID-19 e a HLH e a necessária contínua vigilância, especialmente em populações de maior risco, como as portadoras de doenças imuno-mediadas.

Introduction: People with colorectal cancer (CRC) can present adverse effects, impairing the quality of life related to health (HRQoL). Objective: To validate the QLQ-CR29 module for the assessment of HRQoL, in Chile. Materials and method: Cross-sectional study that included 170 people with CRC. The internal consistency and construct validity (hypothesis tests) were analyzed. Results: 117 patients (68.8%) were evaluated before surgery and 53 (31.2%) after tumor resection. The internal consistency of the QLQCR29 was α = 0.838. The proposed hypotheses were confirmed: The patients evaluated before surgery complained more of "blood/mucus in the stool", "abdominal pain", "hair loss" and "abdominal swelling", while the patients evaluated after presented more "fecal incontinence" (p < 0.05). Before surgery, patients with rectal cancer presented higher values of "urinary frequency", "frequency of stools", "pain in the buttocks", "taste problems" and "embarrassment"; while those with colon cancer complained more of "blood/mucus in stool" (p < 0.05). After surgery, patients with CCR had higher "stool frequency", "flatus" and "embarrassment" (p = 0.004) compared with those with colon cancer (p < 0.05). Ostomized patients presented more "fecal incontinence" and "embarrassment" (p < 0.001). Low significant correlations were observed between most of the dimensions of the QLQ CR29 with the dimensions of the QLQ C30. Conclusion: The Chilean version of the QLQ CR29 module is adequate to assess HRQoL in people with CRC.

Resumen Introducción: Personas con cáncer colorrectal (CCR) pueden presentar efectos adversos, perjudicando la calidad de vida relacionada a la salud (CVRS). Objetivo: Validar el módulo QLQ CR29 para evaluación de la CVRS, en Chile. Materiales y método: Estudio transversal que incluyó 170 personas con CCR. Se analizaron la consistencia interna y validez de constructo del instrumento con test de hipótesis. Resultados: 117 personas (68,8%) fueron evaluadas antes de la cirugía y 53 (31,2%) después de la cirugía. La consistencia interna del QLQ CR29 fue α = 0,838. Fueron comprobadas las hipótesis planteadas: Los pacientes evaluados antes de la cirugía se quejaron más de "sangre/mucosidad en las heces", "dolor abdominal", "pérdida de cabello" e "hinchazón abdominal", mientras que los pacientes evaluados después presentaron más "incontinencia fecal" (p < 0,05). Antes de la cirugía, los pacientes con cáncer de recto CCR presentaron mayores valores de "frecuencia urinaria", "frecuencia de deposiciones", "dolor en las nalgas", "problemas con el gusto" y "vergüenza"; mientras que aquellos con cáncer de colon que se quejaban más de "sangre/mucosidad en las heces" (p < 0,05). Después de la cirugía, los pacientes con cáncer de recto tenían mayor "frecuencia de deposiciones", "eliminación de gases" y "vergüenza" (p = 0,004) en comparación con los con cáncer de colon (p < 0,05). Los pacientes ostomizados presentaron más "incontinencia fecal" y "vergüenza" (p < 0,001). Fueron observadas correlaciones positivas y negativas bajas entre la mayoría de las dimensiones del QLQ CR29 con las dimensiones del QLQ C30. Conclusión: La versión chilena del módulo QLQ CR29 es adecuada para evaluar la CVRS en personas con CCR.

RESUMEN Introducción: Durante el acto de la prescripción se deben relacionar los conocimientos de la terapéutica con los principios de la bioética para contribuir al uso racional de medicamentos. En el artículo se analiza el cumplimiento de los principios bioéticos relacionados con las prescripciones de medicamentos por los médicos generales integrales del municipio Santiago de Cuba. Métodos: Se realizó un estudio descriptivo transversal con una muestra de médicos generales integrales en el que se emplearon métodos teóricos, empíricos y matemáticos estadísticos, así como la triangulación metodológica. Se consideró como variable el cumplimiento de los principios bioéticos relacionados con las prescripciones de medicamentos y cinco indicadores que fueron valorados mediante encuesta, entrevista y observación del desempeño. Resultados: Se encontró que los médicos generales integrales alcanzaron un nivel alto de cumplimiento de los principios bioéticos relacionados con las prescripciones de medicamentos con un valor de media ponderada de 2,94. La valoración de la frecuencia de realización de los indicadores evidenció que tres de ellos fueron considerados del nivel alto, dos de nivel medio y ninguno de nivel bajo. Discusión: los resultados fueron confrontados con otros estudios y se confirma que los médicos generales integrales en Cuba por su formación humanista cumplen con la mayoría de los principios bioéticos en su desempeño profesional.

ABSTRACT Introduction: During the act of prescription, therapeutic knowledge must be related to the principles of bioethics to contribute to the rational use of medications. The article analyzes compliance with bioethical principles related to medication prescriptions by comprehensive general practitioners of the Santiago de Cuba municipality. Methods: A cross-sectional descriptive study was carried out with a sample of comprehensive general practitioners in which theoretical, empirical and mathematical statistical methods were used, as well as methodological triangulation. Compliance with bioethical principles related to medication prescriptions and five indicators that were assessed through a survey, interview and performance observation were considered as variables. Results: It was found that comprehensive general practitioners reached a high level of compliance with bioethical principles related to medication prescriptions with a weighted mean value of 2.94. The assessment of the frequency of carrying out the indicators showed that three of them were considered high level, two medium level and none low level. Discussion: the results were compared with con studies and it is confirmed that comprehensive general practitioners in Cuba, due to their humanistic training, comply with most of the bioethical principles in their professional performance.

ABSTRACT Introduction: Cervical cancer is the third leading cause of death from malignancies worldwide, affecting mainly low- and middle-income countries. By 2020 an incidence of 604,000 new cases was estimated. Objective: To characterize the main hospital indicators of the Cervical Cancer Early Diagnosis Program. Methods: An observational, descriptive and cross-sectional study was carried out to characterize the main hospital indicators of the Program in the Neck Pathology Service of the General Hospital Dr. Bruno Zayas Alfonso of Santiago de Cuba, from January 2020 to December 2022. The study population consisted of 443 women. The data collected were analyzed using descriptive statistic techniques, expressed in frequency and percentages. Results: Of the women studied, 60.9 %had cervical intraepithelial lesion of high degree of malignancy, with 32.6 % positive for cervical cancer. The overall percentage of useless cytological tests was 2.07 and no cells from the processing zone was 4.01, both quality indicators. There was a high significance in terms of the overall coverage rate of women at risk (K=0.615), showing that the results of the cytology largely reflect the diagnosis of histology, with a good agreement. Conclusions: Cervical-vaginal cytology remains the most valuable diagnostic method for detecting cervical intraepithelial neoplasm and early-stage carcinoma in large populations

RESUMEN Introducción: El cáncer cervicouterino ocupa el tercer lugar como causa de defunción por neoplasias malignas a nivel mundial, afectando principalmente a los países de ingresos bajos y medianos. Hacia el 2020 se estimó una incidencia de 604 000 nuevos casos. Objetivo: Caracterizar los principales indicadores hospitalarios del Programa de Diagnóstico Precoz del Cáncer Cervicouterino. Métodos: Se realizó un estudio observacional, descriptivo y transversal, que permitió caracterizar los principales indicadores hospitalarios del Programa en el Servicio de Patología de Cuello del Hospital General Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, de enero del 2020 a diciembre del 2022. La población de estudio estuvo constituida por 443 mujeres. Los datos recopilados fueron analizados mediante técnicas de estadística descriptiva, expresándose en frecuencia y porcentajes. Resultados: De las mujeres estudiadas, 60,9 % presentaron lesión intraepitelial cervical de alto grado de malignidad, con 32,6 % positivo a cáncer cervicouterino. El porcentaje global de pruebas citológicas no útiles fue de 2,07 y sin células de la zona de transformación, de 4,01; ambos indicadores de calidad. Existió una alta significación en cuanto a la tasa de cobertura global de las mujeres en riesgo (K=0,615), demostrando que los resultados de la citología reflejan en gran medida los diagnósticos de la histología, con una buena concordancia. Conclusiones: La prueba citológica cérvico-vaginal sigue siendo el método diagnóstico de mayor valor para detectar neoplasia intraepitelial cervical y carcinoma en estadio precoz en grandes masas de población.

Over regions with sparse observation networks, including South Africa's Northern Cape Province, gridded data sets represent valuable supplementary data sources enabling spatially detailed climate investigations. Their performance is, however, influenced by regional characteristics, thus a performance assessment should be a prerequisite for any regional application. Through a pairwise comparison with eight point-based temperature records, we evaluated the AgERA5 data sets representation of mean summer (November-March; Tms) and winter (May-September; Tmw) temperatures and respective seasonal heatwave and coldwave characteristics across the Northern Cape for 1980-2020. Correlations ranging from 0.48 to 0.92 for Tms and from 0.38 to 0.94 for Tmw reflect relatively strong, but varying, temporal correspondence between the AgERA5 data and stations. Low biases, averaging -0.08 (0.17) °C and ranging from -0.79 to 2.10 (-0.40 to 1.47) °C for Tms (Tmw) were evident. Biases for the heatwave (coldwave) magnitudes were low, averaging -0.38 (0.19) °C², and ranging from -1.55 to 1.47 (-2.05 to 2.91) °C². Biases for the heatwave (coldwave) frequency were also low, but typically overestimated, averaging 1.19 (0.73) days, and ranging from -1.33 to 5.60 (-1.61 to 3.39) days. Biases for the heatwave (coldwave) number were low and typically overestimated, averaging 0.27 (0.08) events, and ranging from -0.28 to 1.40 (-0.39 to 0.39) events. Despite some stations depicting consistently poor performance, the study results support further application of the AgERA5 product for spatiotemporal analyses of mean and extreme temperatures across the Northern Cape, provided limitations are adequately acknowledged. Further application of the fine-resolution AgERA5 product will greatly inform impact-based studies exploring mean and extreme temperature influences over the Northern Cape Province. SIGNIFICANCE: • The AgERA5 product was assessed on its performance in representing average and extreme temperature characteristics over South Africa's Northern Cape Province. • Good comparability between the AgERA5 product and point-based observations supports further application of the AgERA5 across the Northern Cape. • The AgERA5 product offers a spatially detailed picture of mean and extreme temperatures across the Northern Cape, which is valuable for regions where weather stations are not available. • The AgERA5 product is thus important for impact-based studies assessing, for instance, the impact of extreme temperatures on livestock and human health.

RESUMEN Introducción: El cáncer vesicular es una neoplasia infrecuente mundialmente, exceptuando países donde la mortalidad por su causa es alta como Chile, a pesar de ello es el tumor biliar más común, con una incidencia aproximada de 0,8-1,2% y casi exclusivamente en mujeres. Objetivos: Describir la frecuencia, perfil demográfico, clínica, tratamiento y hallazgos anatomopatológicos del cáncer vesicular en pacientes del Hospital Nacional de Itauguá del 2010 al 2020. Materiales y métodos: Se encontraron 19 casos confirmados por biopsia, pero solo 15 fichas estaban completas. El estudio fue retrospectivo, descriptivo y observacional, muestreo no probabilístico de corte transversal. Resultados: De la muestra final (N=15), 13 pacientes fueron mujeres, la edad promedio fue de 60 años. Del total, 4 pacientes ingresaron para cirugía programada con diagnóstico de colecistopatía crónica litiásica y los otros 11 tenían sospecha de tumor vesicular y/o ictericia o colangitis aguda de origen neoplásico probable, todos fueron operados, el motivo de consulta más frecuente fue dolor en hipocondrio derecho, el 99 % fueron adenocarcinomas por anatomía patológica. Conclusión: La etiología principal del cáncer vesicular fue la colelitiasis, es de baja incidencia a nivel nacional, la mayoría de nuestros pacientes se encontraban en estadios terminales, o con poca oportunidad para la resección R0, por lo cual son de mal pronóstico y hasta hoy en día son de difícil detección en etapa inicial. En algunos casos como en 4 de nuestras pacientes el diagnóstico es fortuito mediante el hallazgo histológico en piezas de colecistectomía que fueron intervenidos en principio por patología benigna.

ABSTRACT Introduction: Gallbladder cancer is an infrequent neoplasm worldwide, except for countries where mortality from its cause is high, such as Chile. Despite this, it is the most common biliary tumor, with an approximate incidence of 0.8-1.2% and almost exclusively in women. Objectives: To describe the frequency, demographic profile, clinic, treatment and anatomopathological findings of gallbladder cancer in patients of the Itauguá National Hospital from 2010 to 2020. Materials and methods: 19 biopsy-confirmed cases were found, but only 15 files were complete. The study was retrospective, descriptive and observational, non-probabilistic cross-sectional sampling. Results: Of the final sample (N=15), 13 patients are women; the average age was 60 years. Of the total, 4 patients were admitted for scheduled surgery with a diagnosis of chronic gallstone gallbladder disease and the other 11 had suspected gallbladder tumor and/or jaundice or acute cholangitis of probable neoplastic origin, all were operated on, the most frequent reason for consultation was pain in the hypochondrium right, 99% were adenocarcinomas by pathology. Conclusion: The main etiology of gallbladder cancer was cholelithiasis, it has a low incidence nationwide, most of our patients were in terminal stages, or with little opportunity for R0 resection, for which they have a poor prognosis and up to today they are difficult to detect in the initial stage. In some cases, such as in 4 of our patients, the diagnosis is fortuitous through the histological finding in cholecystectomy specimens that were initially operated on for benign pathology.
