Resumo: Introdução: nos últimos anos, tem havido um aumento na identificação de bactérias multirresistentes (BMDR) em pediatria, tanto de colonização como de infecção, o que tem impactado na morbimortalidade. Uma vigilância rigorosa é realizada no hospital para orientar medidas de prevenção e evitar propagação e contágio intra-hospitalar. Objetivos: descrever a incidência, características epidemiológicas e clínicas de crianças e adolescentes hospitalizados nos quais a BMDR foi identificada por meio de vigilância de infecções associadas à assistência de saúde. Material e métodos: estudo observacional, descritivo e retrospectivo. Foram incluídas crianças e adolescentes internados em hospital de referência nos quais foi identificada MRMO. Variáveis: epidemiológicas, clínicas, microbiológicas e evolutivas. Análise estatística: medidas sumárias. Os padrões éticos de pesquisa foram garantidos. A colonização pelo BMDR foi estudada em crianças com internação superior a 10 dias provenientes de áreas fechadas fora do Hospital de Referência Pediátrica, a amostra foi coletada retal. Foram aplicadas técnicas de detecção e cultura de ácidos nucleicos. Resultados: foram identificados 59 pacientes, 56 colonizações e 3 infecções, a primeira foi uma colonização por KPC em 2016. A partir daí aumentaram para 18 em 2022 e para 14 em julho de 2023. A idade média foi de 9,1 meses (variação de 15 dias a 7 anos). 32 meninas e 27 meninos. Os pacientes vieram de todo o país, com predomínio da região metropolitana (15 Montevidéu e 14 Canelones). 35 pacientes apresentavam comorbidades: 12 prematuros, 2 transplantados, 8 cardiopatias congênitas, 5 com desnutrição grave com nutrição parenteral total, 2 em tratamento com imunossupressores e 1 hemato-oncológico. 37 pacientes receberam antibioticoterapia antes da detecção do BMDR (média de 9 dias). Em relação aos dispositivos médicos, 14 tiveram intubação orotraqueal, 6 receberam acesso venoso central, 3 tiveram traqueostomia, 3 drenagem torácica, 1 drenagem biliar e 1 teve um dispositivo venoso implantável permanente. O diagnóstico na alta foi infecção respiratória em 45, sendo a bronquiolite a mais comum em 29. 56 foram internados em cuidados intensivos, média de 11,6 dias (variação de 1 a 90). Quanto à identificação do agente, as amostras foram swab retal 57, secreções respiratórias 2 e sangue 1. Para swab retal o método de detecção foi o PCR em 39 e cultura em 18. Nos casos de infecções: hemocultura 1 e cultura de secreções respiratórias 2. Porém, o mecanismo de resistência foi identificado por testes imunocromatográficos. As bactérias mais frequentemente identificadas foram Klebsiella pneumoniae 9 e Pseudomonas aeruginosa 6. A distribuição de acordo com o mecanismo de resistência foi NDM 33, KPC 10, OXA-48 9, OXA-51 6, VIM 6, IMP 1, GES 1. Em 3 casos identificados 2 carbapenemases. 6 pacientes morreram (2 infectados e 4 colonizados). 41 pacientes receberam alta hospitalar. Conclusões: através da vigilância, observou-se um aumento na identificação de BMDR, especialmente no último ano. A presença de infecção por BMDR contribuiu para o aumento da mortalidade. A identificação oportuna é essencial para evitar a disseminação e orientar medidas de prevenção.

Summary: Introduction: in recent years, there has been an increase in the identification of Multidrug Resistant Bacteria (MDRB) in pediatrics, regarding both colonization and infection, which has led to morbidity and mortality. Strict surveillance is carried out in the hospital to guide prevention measures and prevent the spread and intra-hospital contagion. Objectives: to describe the incidence, epidemiological and clinical characteristics of hospitalized children and adolescents to whom MDRB was identified through surveillance of infections associated with health care. Material and methods: observational, descriptive, retrospective study. We included children and adolescents admitted to a pediatric reference hospital to whom BMDR had been prescribed. Variables: epidemiological, clinical, microbiological and evolutionary. Statistical analysis: summary measures. Ethical research standards were guaranteed and colonization by BMDR was studied in children with stays of more than 10 days who came from closed areas outside the Pediatric Reference Hospital, the sample was swabbed rectal. Techniques for nucleic acid detection and culture were applied. Results: 59 patients were identified, 56 colonizations and 3 infections, the first was a colonization by KPC in 2016. Since then, they increased to 18 in 2022 and 14 in July 2023. The average age was 9.1 months (range 15 days to 7 years). 32 female and 27 male. The patients came from all over the country, predominantly from the metropolitan area (15 Montevideo and 14 Canelones). 35 patients had comorbidities: 12 preterm, 2 transplanted, 8 congenital heart disease, 5 severe malnutrition with total parenteral nutrition, 2 under treatment with immunosuppressants and 1 hemato oncological. 37 patients received antibiotic therapy prior to MDRB detection (average 9 days). Regarding medical devices, 14 had orotracheal intubation, 6 had a central venous line, 3 had a tracheostomy, 3 had chest drainage, 1 had biliary drainage and 1 had a permanent implantable venous device. The diagnosis at discharge was respiratory infection in 45 cases, bronchiolitis was the most common in 29. 56 were admitted to intensive care, mean 11.6 days (range 1 to 90). Regarding agent identification, 57 samples were rectal swabs, 2 respiratory secretions and blood sample. We used PCR for rectal swab detection in 39 patients and culture in 18. For cases of infections: 1 blood culture and 2 cultures of respiratory secretions, then the resistance mechanism was identified by immunochromatographic tests. The most frequently identified bacteria were Klebsiella pneumoniae 9 and Pseudomonas aeruginosa 6. The distribution according to resistance mechanism was NDM 33, KPC 10, OXA-48 9, OXA-51 6, VIM 6, IMP 1, GES 1. In 3 cases we identified 2 carbapenemase. 6 patients died (2 infected and 4 colonized). 41 patients were discharged. Conclusions: through surveillance, an increase in the identification of MDRB was observed, especially in the past year. The presence of MDRB infection contributed to increased mortality. Timely identification is essential to prevent dissemination and to implement guideline prevention measures.

ABSTRACT Objective: To analyse pharmacological overlap in patients with autism spectrum disorder (ASD) under conscious sedation in a dental office environment, identifying any potential risks and complications. Material and Methods: A critical review was conducted by selecting articles from online databases (Pubmed and Lilacs), using a search algorithm and eligibility criteria. The Medscape® platform was used to verify interactions between drugs commonly used by patients with ASD and medications used for sedation in paediatric dentistry. Results: Due to their polydrug use, children with ASD are at risk of complications, namely Serotonin Syndrome (SS), Neuroleptic Malignant Syndrome (NMS), increase or decrease of the QT interval (QTi) and Torsade de Pointes (TdP), due to pre-existence of metabolic syndrome, deepening the sedation level or even leading to a decrease in the sedative capacity of the drugs used. Conclusion: It is essential to assess better drug interaction in ASD patients submitted to sedation. The severity of the disorder and the need for sedation for dental treatment are directly proportional. However, increases in sedative doses tend to increase risks and complications in children with ASD. Objective (ASD environment Methods Pubmed Lilacs, Lilacs , Lilacs) criteria Medscape dentistry Results use SS, SS (SS) NMS, NMS (NMS) QTi (QTi TdP, TdP (TdP) preexistence pre existence syndrome Conclusion proportional However (SS (NMS (TdP

Abstract The sustainability of urban areas nowadays faces significant challenges, due to high levels of pollution caused by population density. Therefore, the availability of water resources appears to be becoming increasingly compromised, as a result of inappropriate management of the solid and liquid waste generated by different human activities. The Ocloro River is a clear example of this problem, as evidenced by the deterioration of its environmental health. A mixed methodology was used to know about it, the first method was to characterize water quality using physicochemical and microbiological parameters, later on, the determination of the Duch index, giving a total of 16 samples of class 5 “extreme contamination” and 4 samples of class 4 “severe contamination”, from 2019 to 2021. In the second stage, a perception survey was conducted among a specific sector of the Barrio Luján population, approaching information from 80 homes, where 54 people indicated that the river pollution had affected them; additionally, the majority rated the level of pollution as 8, where 10 was the value with the highest level of pollution. Finally, the POSH method was used, which allowed the identification of some of the main point sources of pollution near the river, determining 27.1 % of high pollution, 22.3 % of moderate pollution, and 50,6 % of reduced pollution; this last one corresponds to the northern part of the river micro-basin in the communities of San Pedro, Los Yoses, and Francisco Peralta.

Resumen La sostenibilidad de las zonas urbanas hoy en día enfrenta grandes desafíos, debido a los altos niveles de contaminación causados por la densidad poblacional. Por consiguiente, la disponibilidad del recurso hídrico se ve cada vez más comprometido, producto a la inapropiada gestión de residuos sólidos y líquidos, generados por diferentes actividades humanas. El río Ocloro es un claro ejemplo de esta problemática, el deterioro de su salud ambiental es una evidencia de ello. Para conocerla, se utilizó una metodología mixta, el primer método fue la caracterización de la calidad del agua mediante parámetros fisicoquímicos y microbiológicos, posteriormente, la determinación del índice holandés, obteniendo un total de 16 muestras clase 5 “contaminación muy severa” y 4 muestras clase 4 “contaminación severa”, del 2019 al 2021. En la segunda etapa se aplicó una encuesta de percepción entre un sector específico de la población de Barrio Luján, alcanzando información de 80 viviendas, donde 54 personas indicaron haber tenido afectación por la contaminación del río; asimismo, la mayoría calificó el nivel de contaminación en 8, donde 10 era el valor con mayor nivel de contaminación. Finalmente se utilizó el método POSH, el cual permitió identificar algunas de las principales fuentes puntuales de contaminación en las cercanías del río, determinando 27,1 % de contaminación elevada, 22,3 % de contaminación moderada y 50,6 % de contaminación reducida; este último le corresponde a la parte norte de la microcuenca en los barrios de San Pedro, Los Yoses y Francisco Peralta.

Resumo Estudos emergentes indicam a persistência dos sintomas além da fase aguda da COVID-19. O comprometimento cognitivo foi observado em alguns indivíduos durante meses após a infecção. Atualmente, há pouco conhecimento sobre os domínios cognitivos específicos que sofrem alterações durante a síndrome pós-aguda da COVID-19 e o possível impacto da gravidade da doença na cognição. O objetivo desta revisão é examinar estudos que relataram comprometimento cognitivo na COVID-19 pós-aguda, categorizando-os em fases subaguda e crônica. A metodologia proposta pela Joanna Briggs Institute foi seguida neste estudo. Os estudos incluídos foram publicados entre dezembro de 2019 e dezembro de 2022. A busca foi realizada no PubMed, PubMed PMC, BVS – BIREME, Embase, SCOPUS, Cochrane, Web of Science, Proquest, PsycInfo e EBSCOHost. A extração de dados incluiu detalhes específicos sobre a população, os conceitos, o contexto e as principais descobertas ou recomendações relevantes para os objetivos da revisão. Um total de 7.540 registros foi identificado e examinado, e 47 artigos foram incluídos. Os domínios cognitivos mais frequentemente relatados como alterados de 4 a 12 semanas após a COVID-19 aguda foram linguagem, memória episódica e função executiva e, após 12 semanas, os domínios mais afetados foram atenção, memória episódica e função executiva. Os resultados dessa revisão de escopo destacam que adultos com síndrome pós-aguda da COVID-19 podem apresentar comprometimento em domínios cognitivos específicos. COVID19.

Abstract Emerging studies indicate the persistence of symptoms beyond the acute phase of COVID-19. Cognitive impairment has been observed in certain individuals for months following infection. Currently, there is limited knowledge about the specific cognitive domains that undergo alterations during the post-acute COVID-19 syndrome and the potential impact of disease severity on cognition. The aim of this review is to examine studies that have reported cognitive impairment in post-acute COVID-19, categorizing them into subacute and chronic phases. The methodology proposed by JBI was followed in this study. The included studies were published between December 2019 and December 2022. The search was conducted in PubMed, PubMed PMC, BVS – BIREME, Embase, SCOPUS, Cochrane, Web of Science, Proquest, PsycInfo, and EBSCOHost. Data extraction included specific details about the population, concepts, context, and key findings or recommendations relevant to the review objectives. A total of 7,540 records were identified and examined, and 47 articles were included. The cognitive domains most frequently reported as altered 4 to 12 weeks after acute COVID-19 were language, episodic memory, and executive function, and after 12 weeks, the domains most affected were attention, episodic memory, and executive function. The results of this scoping review highlight that adults with post-acute COVID-19 syndrome may have impairment in specific cognitive domains. COVID19.

ABSTRACT Introduction: The COVID-19 pandemic forced our unit to alternate in-person consultations with telephone consultations, without this increasing urgent visits. Therefore, it seemed necessary to know the patient's opinion regarding this matter. Objective: To assess the satisfaction of patients receiving peritoneal dialysis with the quality of care received through a mixed model of in-person and teleconsultations. Material and Method: PA descriptive cross-sectional study was conducted between February and March 2021, using an anonymous telephone survey conducted by an independent interviewer. Inclusion criteria: aged over 18, receiving peritoneal dialysis, and giving their consent. Variables collected: age, sex, primary caregiver, provider (Baxter®/Fresenius®), hospital admission (Yes/No). Satisfaction questionnaire (9 questions): 2 open-ended, 1 semi-closed with a dichotomous response and free text, and 6 closed with Likert-type response from 0-10. Results: Of the 78 peritoneal dialysis patients, 71 participants were included. 59.1% (n=42) were men, with an average age of 66.1 years (23.33-91.23 years). The average score for healthcare received through the mixed model of visits was 9.5 ±1.13. Regarding aspects to improve in phone consultations, 61.2% (n=41) considered it unnecessary to assign a specific time, 11.2% (n=8) stated the need to receive changes in writing, 4.5% (n=3) requested an improvement in the request for laboratory analysis at the healthcare center, and none considered video calls necessary. Conclusions: The patient's satisfaction with our mixed model of visits seems to reflect a good quality of care, subject to improvement and individualization.

RESUMEN Introducción: La infección del orificio de salida del catéter de diálisis peritoneal es una complicación importante en la diálisis peritoneal, que puede evolucionar hacia una tunelitis y/o infección peritoneal, lo que suele conllevar una retirada del mismo. Objetivo: Analizar el uso de mupirocina en la cura del orificio sano y su repercusión en la ratio de infecciones del orificio de salida y en el porcentaje de infecciones peritoneales dependientes de catéter. Material y Método: Estudio observacional retrospectivo, en una unidad de diálisis peritoneal provincial. Se incluyeron a todos los pacientes mayores de 18 años, que realizaron diálisis peritoneal en domicilio del 01/01/2019 hasta el 31/12/2021. Las variables analizadas, fueron: sexo , ratio de infección de orificio anual, gérmenes responsables, infecciones peritoneales dependientes de catéter y aparición de resistencias. Los datos se obtuvieron del registro anual de la unidad. Resultados: Tras la incorporación del uso de mupirocina 2 veces por semana en la cura del orificio de salida sano disminuyó la ratio de infección del orificio de salida, pasando de 0,47 episodio/paciente/año en 2019, a una ratio de 0,32 en 2020 y de 0,16 en 2021, disminuyendo el porcentaje de infecciones peritoneales dependientes de catéter de 38% en 2019, al 30% en 2020 y del 8% en 2021. No se han objetivado resistencias a antibióticos, ni otros efectos indeseados. Conclusiones: El uso de mupirocina en nuestra unidad parece ser eficaz en la reducción de las infecciones del orificio de salida, y de las infecciones peritoneales dependientes de catéter.

ABSTRACT Introduction: Outflow tract infection is an important complication in peritoneal dialysis, mainly because it can progress to tunelitis and/or catheter-dependent peritoneal infection that often leads to catheter removal. Objective: To analyse the mupirocin application in the management of the healthy exit site and the impact on the infection rate and the percentage of catheter-dependent peritoneal infections. Material and Method: Retrospective observational study in a provincial peritoneal dialysis unit. Patients over 18 years of age who underwent peritoneal dialysis at home from 01/01/2019 to 31/12/2021 were included. Variables analysed were: sex, yearly orifice infection rate, responsible germs, catheter-dependent peritoneal infections and appearance of resistance. Data were obtained from the unit’s annual registry. Results: Twice-weekly mupirocin application in healthy peritoneal catheter exit site care has decreased the rate of exit site infections from 0.47 episode/patient/year in 2019 to 0.32 in 2020 and 0.16 in 2021, decreasing the percentage of catheter-dependent peritoneal infections from 38% in 2019 to 30% in 2020 and 8% in 2021. No resistance has been observed. Conclusions: Mupirocin application in our unit appears to be effective in reducing exit site infections and catheter-dependent peritoneal infections.

Resumo Avaliar a resistência à flexão (FS) e o módulo de flexão (FM) de uma cerâmica comercial 3Y-TZP após envelhecimento artificial, e com ou sem dois tempos de aplicação de plasma não térmico (NTP). Além disso, a transformação de fase cristalina e a nano-topografia de superfície após a aplicação de NTP, durante diferentes períodos de envelhecimento, foram avaliadas. Noventa barras 3Y-TZP (45x4x3 mm) foram feitas para testes de FS e FM, e distribuídas em nove grupos (n=10): sem NTP/sem envelhecimento (Controle); sem NTP/4h de envelhecimento; sem NTP/30h de envelhecimento; 10sNTP/sem envelhecimento; 10sNTP/4h; 10sNTP/30h; 60sNTP/sem envelhecimento; 60sNTP/4h e 60sNTP/30h. O envelhecimento artificial acelerado foi simulado em autoclave (134º C a 2 bar) por até 30 horas. FS e FM foram avaliados em máquina de ensaio universal e os dados analisados pela ANOVA e teste de Tukey (α = 0,05). A mudança de volume da fase monoclínica de zircônia (MPV) foi avaliada usando difração de raios-X e nano-topografia de superfície foi avaliada utilizando microscopia de força atômica (baseline até 30h). A aplicação do NTP não influenciou a FS e FM da zircônia. Comparado ao Controle (“sem NTP/sem envelhecimento”), a FS das amostras de zircônia tratadas por 30 horas em autoclave (“sem NTP/30h de envelhecimento”) aumentou. O envelhecimento artificial por 30 horas aumentou significativamente a FM da zircônia, independente do tempo de aplicação do NTP. O MPV tendeu a aumentar em função do aumento do tempo de envelhecimento para todos os grupos, que pode ter resultado nas irregularidades superficiais observadas com 30 horas de envelhecimento. O NTP não afetou as propriedades da zircônia testadas, mas o envelhecimento por 30 horas pode alterar a FS, FM e MPV da zircônia.

Abstract To evaluate the flexural strength (FS) and flexural modulus (FM) of a commercial 3Y-TZ0P ceramic after artificial aging and either without or with two application times of non-thermal plasma treatments (NTP). In addition, changes in crystalline phase transformation and surface nano-topography after NTP application, during different aging periods, were evaluated. Ninety 3Y-TZP bars (45x4x3 mm) were made for FS and FM testing, and assigned to nine groups (n=10): no NTP/no aging (Control); no NTP/4h aging; no NTP/30h aging; 10s NTP/no aging; 10s NTP/4h aging; 10s NTP/30h aging; 60s NTP/no aging; 60s NTP/4h aging and 60s NTP/30h aging. Artificial accelerated aging was simulated using an autoclave (134º C at 2 bar) for up to 30h. FS and FM were assessed using a universal testing machine and data analyzed using a ANOVA and Tukey test (α=0.05). The volume change in zirconia monoclinic phase (MPV) was evaluated using X-ray diffraction and surface nano-topography was assessed using atomic force microscopy (baseline until 30h-aging). NTP application did not influence the FS and FM of zirconia. Compared to the Control (no NTP/no aging), the FS of zirconia samples treated for 30 hours in autoclave (“no NTP/30h aging” group) increased. Artificial aging for 30 hours significantly increased the FM of zirconia, regardless of NTP application. MPV tended to increase following the increase in aging time, which might result in the surface irregularities observed at 30h-aging. NTP did not alter the zirconia properties tested, but 30h-aging can change the zirconia FS, FM and MPV.

Resumo Objetivo analisar associações diretas e indiretas entre autoavaliação de saúde, indicadores objetivos de saúde e neuroticismo em idosos Método Os dados foram extraídos dos registros de seguimento (2016-2017) do Estudo da Fragilidade em Idosos Brasileiros (Estudo FIBRA), de base populacional, sobre fragilidade e fatores associados na velhice. Trezentos e noventa e sete indivíduos com idade a partir de 73 anos no seguimento responderam a um item sobre autoavaliação de saúde. Polimedicação, dor crônica e multimorbidade foram autorrelatadas, fadiga foi mensurada pela CES-D, depressão pela EDG e neuroticismo pelo inventário NEO-PI-R. Foi realizada análise de caminhos, para verificar associações diretas e indiretas entre autoavaliação de saúde, indicadores objetivos de saúde e neuroticismo. Resultados Relações mais robustas foram observadas entre sexo e multimorbidade, depressão e neuroticismo, e neuroticismo e autoavaliação de saúde. Destaca-se que neuroticismo mediou a relação entre idade, dor crônica, multimorbidade e depressão com autoavaliação de saúde. Conclusão O neuroticismo é um importante mediador da relação entre autoavaliação de saúde e indicadores objetivos de saúde. Trabalhos longitudinais são necessários para explicar as relações observadas.

Abstract Objective to analyze the direct and indirect associations between self-rated health, objective health indicators and neuroticism in older adults. Method Data were extracted from follow-up records (2016-2017) of the Study of Frailty in Brazilian Elderly (FIBRA Study), a population-based study of frailty and associated variables in old age. Three hundred and ninety-seven individuals aged 73 years and over at follow-up answered an item on self-rated health. Polimedication, chronic pain and multimorbidity were self-reported, fatigue was measured by CES-D, depression by GDS and neuroticism by NEO-PI-R. Path analysis was performed to verify direct and indirect associations between self-rated health, objective health indicators and neuroticism in the follow-up. Results Neuroticism mediated the relationship between sex and age with self-rated health, and between depression and self-rated health. More robust relationships were observed between depression and neuroticism, pain and neuroticism, and sex and neuroticism; the least robust occurred between age and fatigue. Conclusion Neuroticism is an important mediator of the relationship between self-rated health and objective health indicators. Longitudinal work is needed to

ABSTRACT Introduction: The abdominal perimeter and endurance to intermittent efforts reflected in VO2max are two major indicators; the first for cardiovascular risk and the second for maximum aerobic capacity. This study will make it possible to determine whether abdominal perimeter measurements are related to the subject's ability to respond to intermittent efforts. Objective: Determine the association between the abdominal perimeter and the endurance to intermittent efforts reflected in the VO2max. Methods: The participants were 91 men and 22 female students of the Bachelor's Degree in Physical Education, Recreation and Sports of the University of Pamplona. For the assessment of intermittent endurance, the intermittent fitness test 30-15 (30-15 ITF) was used with which the VO2max was determined. The abdominal perimeter was taken taking into account the criteria of the International Diabetes Federation. The tabulation and analysis of data was carried out in the PSPP statistical package, applying the Kolmogorov-Smirnov normality test for men and Shapiro-Wilk for women, and, Spearman's correlational coefficient (p < 0,05) (p-value of 0,05). Results: A negative association was found between the variables abdominal girth and the indicator of endurance to intermittent efforts VO2max, in men (r = -0,17) and in women (r = 0,09), however, for both sexes, this relationship was not statistically significant (p < 0,05). Conclusion: It is concluded that, the abdominal perimeter is not significantly related to resistance to intermittent efforts in physically active university students.

RESUMEN Introducción: El perímetro abdominal y la resistencia a esfuerzos intermitentes, reflejada en el VO2máx, son dos grandes indicadores; el primero del riesgo cardiovascular y el segundo de la capacidad aeróbica máxima. Este estudio permitirá determinar si las mediciones del perímetro abdominal tienen relación con la capacidad del sujeto de responder a esfuerzos intermitentes. Objetivo: Determinar la asociación entre el perímetro de cintura y la resistencia a esfuerzos intermitentes reflejada en el VO2máx. Métodos: Los participantes fueron 91 hombres y 22 mujeres estudiantes de la Licenciatura en Educación Física, Recreación y Deportes de la Universidad de Pamplona. Para la valoración de la resistencia intermitente se empleó el test de fitness intermitente 30-15 (30-15 ITF) con el cual se determinó el VO2máx. Se realizó la toma del perímetro de cintura teniendo en cuenta los criterios de la Federación Internacional de Diabetes. La tabulación y análisis de datos se llevó a cabo en el paquete estadístico PSPP, con la prueba de normalidad de Kolmogorov - Smirnov para hombres y Shapiro - Wilk para mujeres, y el coeficiente correlacional de Spearman (p < 0,05) (valor p de 0,05). Resultados: Se encontró una asociación negativa entre las variables perímetro abdominal e indicador de resistencia a esfuerzos intermitentes VO2máx, en hombres (r = -0,17) y en mujeres (r = 0,09), no obstante, para ambos sexos esta relación no fue estadísticamente significativa (p < 0,05). Conclusión: Se concluye que el perímetro abdominal no está relacionado de forma significativa con la resistencia a esfuerzos intermitentes en universitarios físicamente activos.

ABSTRACT Objective: Determine the difference in incidence of transfusion-associated necrotizing enterocolitis in preterm newborns with and without implementation of a peri-transfusion fasting protocol. Methods: Retrospective observational study. All preterm newborns that were transfused with red blood cell units during the period from July 2015 to October 2016 in the newborns´ unit at a third level of care center in Colombia were included. The peri-transfusion fasting protocol started on April 2016. Transfusion-associated necrotizing enterocolitis was defined as necrotizing enterocolitis presented within 48 hours after the transfusion. Demographic variables, feeding, number of transfusions and variables associated with necrotizing enterocolitis were analyzed. Results: During the study time, 148 premature newborns needed at least one transfusion of red blood cells that accounted for 385 transfusion events. Seven cases of transfusion-associated necrotizing enterocolitis were reported. The overall cumulative incidence was 4.7% (3.6% with peri-transfusion fasting protocol and 6.3% without protocol), the overall incidence rate of transfusion-associated necrotizing enterocolitis was 18/1000 people-transfusion (IC 95% 7-37/1000 people-transfusion); it was higher in the group without protocol (28/1000 people-transfusion) than in the group with protocol (12/1000 people-transfusion), but without statistical significance. Conclusions: Implementation of the peri-transfusion fasting protocol may decrease the incidence and severity of necrotizing enterocolitis associated with transfusion. Prospective studies are required to establish the relationship between enteral feeding during transfusion and necrotizing enterocolitis.

RESUMEN Objetivo: Determinar la diferencia de incidencia de enterocolitis necrotizante asociada a transfusión en recién nacidos pretérmino con y sin implementación de un protocolo de ayuno peritransfusional. Métodos: Estudio observacional retrospectivo. Se incluyeron todos los recién nacidos pretérmino que fueron transfundidos con unidad de glóbulos rojos entre julio 2015 y octubre 2016 en la unidad de recién nacidos un centro de tercer nivel de Colombia. El protocolo de ayuno peritransfusional se inició a partir de abril 2016. La enterocolitis necrotizante asociada a transfusión se definió como enterocolitis necrotizante presentada dentro de las 48 horas posteriores a la transfusión. Se analizaron variables demográficas, alimentación, número de transfusiones y variables asociadas a enterocolitis necrotizante. Resultados: Durante el tiempo de estudio, 148 recién nacidos prematuros necesitaron al menos una transfusión de glóbulos rojos que representaron 385 eventos de transfusión. Se informaron siete casos de enterocolitis necrotizante asociada a transfusión. La incidencia acumulada global fue 4,7 % (3,6 % con protocolo de ayuno peritransfusional y 6,3 % sin protocolo), la tasa de incidencia global de enterocolitis necrotizante asociada a transfusión fue 18/1000 personas-transfusión (IC95% 7-37/1000 personas-transfusión), mayor en el grupo sin protocolo (28/1000 personas-transfusión) que en el grupo con protocolo (12/1000 personas-transfusión), pero sin significación estadística. Conclusiones: La implementación del protocolo de ayuno peritransfusional podría disminuir la incidencia y gravedad de la enterocolitis necrotizante asociada a transfusión. Se requieren estudios prospectivos para establecer la relación entre la alimentación enteral durante la transfusión y la enterocolitis necrotizante.

SUMMARY Introduction: cervical cancer is a health problem for the humankind. The study of its risk factors stands as a priority for the Cuban health system. Objective: to know the behavior of cervical cancer risk factors in students of the studies of Hygiene-Epidemiology-Vector Surveillance and Control of the Matanzas University of Medical Sciences. Materials and methods: retrospective, cross-sectional, descriptive research inserted into the Branch Program of Chronic Non-communicable Diseases. It dealt with the universe of 50 students of the studies of Hygiene-Epidemiology-Vectorial Surveillance and Control of the Matanzas University of Medical Sciences. Results: in relation to the age of beginning to have sexual relationships, it was observed the predominance of the age of 14 years. The presence of multiple sexual partners, unprotected intercourse, use of contraceptive tablets, smoking habit, gynecological manipulations, and sexually transmitted infections are other risk factors found. Special significance had the existence of multiple sexual partners and the use of contraceptive tables. Among the motivations leading to early beginning to have sexual relationships, experiencing new sensations with 28 % and seeking for pleasure with the couple with 55 % stood out. 92 % did not know the disease’s risk factors. Conclusions: the students presented pronounced magnitude risk factors of suffering cervical cancer.

RESUMEN Introducción: el cáncer cérvico uterino constituye un problema de salud para la humanidad. El estudio de sus factores de riesgo representa prioridad para el sistema de salud cubano. Objetivo: conocer el comportamiento de los factores de riesgo del cáncer cérvico uterino, en estudiantes de las carreras de Higiene-Epidemiología-Vigilancia y Lucha Antivectorial de la Universidad de Ciencias Médicas de Matanzas. Materiales y métodos: investigación descriptiva, transversal, retrospectiva que se insertó en el Programa Ramal Enfermedades Crónicas no Transmisibles. Se trabajó con el universo de 50 alumnos de las carreras de Higiene- Epidemiología-Vigilancia y Lucha Antivectorial de la Universidad de Ciencias Médicas de Matanzas. Resultados: según edad de inicio de las relaciones sexuales, se observó mayor predominio a los 14 años de edad. Presencia de múltiples compañeros sexuales, relaciones sexuales desprotegidas, uso de tabletas anticonceptivas, hábito de fumar, manipulaciones ginecológicas, así como infecciones de transmisión sexual. Especial significación tuvo la evidencia de cifras significativas de múltiples compañeros sexuales y el uso de tabletas anticonceptivas. Entre la distribución de motivos que impulsaron al inicio de relaciones sexuales, se destacaron los de experimentar sensaciones nuevas con el 28 %, y búsqueda de placer con la pareja en 55 %. El 92 %, desconocían los factores de riesgo de la enfermedad. Conclusiones: los estudiantes presentaron factores de riesgo de considerable magnitud de padecer cáncer cérvico uterino.
