Abstract Introduction: nearly one-third of psoriatic arthritis (PsA) patients suffer from anxiety and/or depression. The objectives of this study were to estimate the prevalence of depression and anxiety in patients with PsA, establish the relationship with different socio-demographic and clinical factors, and determine the effect of depression and anxiety on various components of disease activity scores. Materials and methods: patients with PsA who met the Classification criteria of psoriatic arthritis (CASPAR) criteria were included. Depression was defined according to the Patient Health Questionnaire-9 (PHQ-9) and anxiety according to the General Anxiety Disorder-7 (GAD-7) questionnaire. Multiple logistic regression was performed to identify variables associated with anxiety and depression. Results: 100 patients were included. The prevalence of major depression and anxiety was 26% and 59%, respectively. Patients with major depression had higher disease activity, pain, fatigue and anxiety, less formal education and worse quality of life. In comparison those patients with anxiety showed higher disease activity, pain and fatigue and worse quality of life and functional capacity. High disease activity and low formal education were independently associated with the existence of major depression. Conclusions: patients with PsA who suffer from major depression and anxiety show higher disease activity levels.

Resumen Introducción: un tercio de los pacientes con artritis psoriásica (APs) sufre ansiedad y/o depresión, lo que podría impactar negativamente en la actividad de la enfermedad. Los objetivos de este estudio fueron: evaluar la prevalencia de depresión y ansiedad en pacientes con APs, estudiar su asociación con diferentes factores socio-demográficos y clínicos, y determinar el efecto sobre los diferentes componentes de los índices compuestos de la actividad de la APs. Materiales y métodos: se incluyeron pacientes con APs que cumplían criterios de la Classification Criteria of Psoriatic Arthritis (CASPAR). La depresión se definió según el Patient Health Questionnaire-9 (PHQ-9) y la ansiedad según el cuestionario General Anxiety Disorder-7 (GAD-7). Se realizó regresión logística múltiple para identificar variables asociadas a ansiedad y depresión. Resultados: se incluyeron 100 pacientes con APs, de los cuales el 26% y el 59% presentaron depresión mayor y ansiedad respectivamente. Los pacientes con depresión mayor tuvieron mayor actividad de la enfermedad, dolor, fatiga, ansiedad, y menor educación formal y peor calidad de vida. Aquellos con ansiedad manifestaron mayor actividad de la enfermedad, dolor y fatiga, y peor calidad de vida y capacidad funcional. La alta actividad de la enfermedad y la menor educación formal se asociaron independientemente con depresión mayor. Conclusiones: la presencia de depresión mayor y ansiedad se asoció con mayor actividad de la enfermedad en pacientes con APs.

Abstract COVID-19 is a global public health issue due to its epidemic nature that, to date, lacks pharmacological treatment. However, some COVID-19 vaccines have been authorized for emergency use, although the duration of their protection, their ability to interrupt viral transmission, and their efficacy against emerging variants of SARS-CoV-2 are being studied. Chile's SARS-CoV-2 vaccination campaign required design and planning, like any other campaign. This process included the prioritization of risk groups for vaccination given the limited supply of COVID-19 vaccines globally. Throughout 2020, CAVEI issued recommendations on the prioritization of population groups to be vaccinated against SARS-CoV-2 in response to different needs and in accordance with available evidence. These recommendations are consolidated in Table 1 in this report. In summary, it was recommended that healthcare workers, people in long-term residences and essential State personnel be vaccinated in phase 1. In phase 2, persons over 65 years of age and people with comorbidities. In phase 3, essential tasks workers and, lastly, the general population.

Resumen El COVID-19 es un problema de salud pública mundial por su carácter epidémico que, a la fecha, carece de tratamiento farmacológico. Sin embargo, ya se cuenta con algunas vacunas autorizadas para uso en emergencia, aunque la duración de su protección, su capacidad para interrumpir la transmisión viral y su eficacia frente a variantes emergentes de SARS-CoV-2 se encuentran en estudio. La campaña de vacunación contra SARS-CoV-2 de Chile requirió de diseño y planificación, como toda campaña. Parte de estos fue la priorización de grupos objetivo de vacunar, necesaria debido a que el mundo se vería enfrentado a un suministro limitado de vacunas COVID-19. En distintos momentos del año 2020, el CAVEI emitió recomendaciones sobre priorización de grupos de población a vacunar contra SARS-CoV-2, respondiendo a diferentes necesidades y según la evidencia disponible en cada instancia. Éstas se consolidan en la Tabla 1 de este informe. Resumidamente, en fase 1 se recomendó vacunar al personal de salud, residencias de larga estadía y personal crítico del Estado. En fase 2, a personas mayores de 65 años y población con comorbilidades. En fase 3, a personas que cumplen labores esenciales y, finalmente, a la población general.

Abstract Genetic defects affecting the remethylation pathway cause hyperhomocysteinemia. Isolated remethylation defects are caused by mutations of the 5, 10-methylenetetrahydrofolate reductase (MTHFR), methionine synthase reductase(MTRR), methionine synthase(MTR), and MMADHC genes, and combined remethylation defects are the result of mutations in genes involved in the synthesis of either methylcobalamin or adenosylcobalamin, that is, the active cofactors of MTRR and methylmalonyl-CoA mutase. Diagnosis is based on the biochemical analysis of amino acids, homocysteine, propionylcarnitine, methylmalonic acid, S-adenosylmethionine, and 5-methylentetrahydrofolate in physiological fluids. Gene-by-gene Sanger sequencing has long been the gold standard genetic analysis for confirming the disorder and identifying the gene involved, but massive parallel sequencing is now being used to examine all those potentially involved in one go. Early treatment to rescue metabolic homeostasis is based on the following of an appropriate diet, betaine administration, and, in some cases, oral or intramuscular administration of vitamin B12 or folate. Elevated ROS levels, apoptosis, endoplasmic reticulum (ER) stress, the activation of autophagy, and alterations in Ca2+ homeostasis may all contribute toward the pathogenesis of the disease. Pharmacological agents to restore the function of the ER and mitochondria and/or to reduce oxidative stress-induced apoptosis might provide novel ways of treating patients with remethylation disorders.

OBJETIVO: analisar a associação entre homicídios e indicadores de segurança pública no MSP entre 1996 e 2008, após controle para taxa de desemprego e proporção de jovens na população. METODOLOGIA: estudo ecológico de série temporal, tendo como unidade de análise o Município de São Paulo (MSP), entre 1996 e 2008. Variável dependente: óbitos por homicídio; variáveis independentes principais: taxa de aprisionamento-encarceramento (TAE), o acesso a armas de fogo (AAF), e a atividade policial (ATP). A análise dos dados foi realizada com o software Stata.IC 10.0. Modelos de regressão binomial negativa simples e multivariados foram construídos. RESULTADOS: A análise univariada demonstrou associação entre óbitos por homicídio e TAE e entre óbitos e ATP. O AAF não se mostrou associado à redução no número de óbitos por homicídios (p > 0,05). Após ajuste houve perda da significância na associação com ambos indicadores de Segurança Pública. CONCLUSÕES: No MSP o papel das ações de segurança pública perdem importância como fatores explicativos para a redução nos níveis de homicídios após controle para taxa de desemprego e redução na proporção de jovens. Os resultados reforçam a importância dos fatores socioeconômicos e demográficos para a mudança no cenário da segurança em São Paulo.

The scope of this paper was to analyze the association between homicides and public security indicators in São Paulo between 1996 and 2008, after monitoring the unemployment rate and the proportion of youths in the population. A time-series ecological study for 1996 and 2008 was conducted with São Paulo as the unit of analysis. Dependent variable: number of deaths by homicide per year. Main independent variables: arrest-incarceration rate, access to firearms, police activity. Data analysis was conducted using Stata.IC 10.0 software. Simple and multivariate negative binomial regression models were created. Deaths by homicide and arrest-incarceration, as well as police activity were significantly associated in simple regression analysis. Access to firearms was not significantly associated to the reduction in the number of deaths by homicide (p>0,05). After adjustment, the associations with both the public security indicators were not significant. In São Paulo the role of public security indicators are less important as explanatory factors for a reduction in homicide rates, after adjustment for unemployment rate and a reduction in the proportion of youths. The results reinforce the importance of socioeconomic and demographic factors for a change in the public security scenario in São Paulo .

Objective: To report the treatment of a clinical case with central placenta previa accreta. During pregnancy image diagnosis (ultrasound and magnetic resonance imaging) revealed localization and penetration of the placenta into the uterine wall. Just before delivery to reduce the bloss loss and avoid maternal hypotension and facilitate surgery, intra arterial balloons were placed on both hypogastric arteries by the radiologist; intravascular monitoring was installed by anesthesist and urologist put in ureteral catheters. The delivery was by cesarean section and followed by histerectomy leaving the placenta in situ. The case correspond to a woman of 32 years old that had 2 previous cesarean section. During this pregnancy bled a few times and was delivered at weeks 36th. During surgery she was stable, requiring one unit of red blood cells and four liters of coloids and crystaloids. Post-operative course was with no problems. The pathologist report a placenta percreta with no bladder involvement, agreeing with the vascular lakes image and the cystoscopy. Conclusion: This case reveals the benefits of multidisciplinary approach to manage severe complications of pregnancy such as placenta previa and the degree of accretism.

Objetivo: Evaluar la eficacia y resultados del tratamiento de la placenta acreta previa central en un caso clínico. Durante el embarazo los métodos diagnósticos por imágenes (ultrasonido y resonancia nuclear magnética) precisaron la localización y penetración de la placenta en la pared uterina. En el período inmediato antes del parto, para disminuir la hemorragia, evitar la hipotensión materna y facilitar el procedimiento quirúrgico, se colocaron balones intraarteriales en ambas ilíacas internas por radiólogo intervencionista, catéteres para monitoreo hemodinámico invasivo por anestesiólogo y catéteres ureterales por urólogo. La resolución del parto fue por cesárea-histerectomía sin remoción de la placenta. El caso correspondió a una paciente de 32 años con cesárea en dos partos anteriores, metrorragia episódica y que fue interrumpida en la semana 36. Durante toda la intervención permaneció hemodinámicamente estable requiriendo 1 unidad de glóbulos rojos, 4 litros entre coloides y cristaloides y el posoperatorio fue sin incidentes. El examen histo-patológico demostró percretismo de la pared uterina sin invasión vesical, concordante con las imágenes de lagunas vasculares y la citoscopia. Conclusión: El caso demuestra el beneficio del tratamiento especializado multidisciplinario de embarazos con complicaciones graves como la placenta previa con diferentes grados de acretismo.

Ao longo da primeira década dos anos 2000, a taxa de mortalidade por homicídio (TMH) apresentou uma expressiva redução no Estado e no Município de São Paulo (MSP). O objetivo deste estudo é descrever a evolução das TMH e de indicadores sociodemográficos, de investimento em políticas sociais e segurança pública, e analisar a correlação entre a evolução das TMHs e das variáveis independentes no MSP entre 1996 e 2008. Foi realizado um estudo ecológico de série temporal, exploratório. As seguintes variáveis foram incluídas: TMH por 100.000 habitantes, indicadores sociodemográficos, investimentos em políticas sociais e de segurança pública. Foram calculadas as médias móveis de todas as variáveis e a tendência foi analisada através de Regressão Linear. Foram calculadas as variações percentual anual, média anual e percentual periódica, e a associação foi testada por meio da análise de correlação de Spearman entre a variação percentual anual das variáveis. Foram encontradas correlações com a proporção de jovens na população (r = 0,69), taxa de desemprego (r = 0,60), investimento estadual em educação e cultura (r = 0,87) e saúde e saneamento (r = 0,56), investimento municipal (r = 0,68) e estadual (r = 0,53) em segurança pública, armas apreendidas (r = 0,69) e taxa de encarceramento-aprisionamento (r = 0,71). Os resultados apresentados permitem sustentar a hipótese de que alterações demográficas, aceleração da economia, em especial a queda do desemprego, investimentos em políticas sociais e mudanças nas políticas de segurança pública atuam sinergicamente para a redução da TMH em São Paulo. Torna-se necessário o desenvolvimento de modelos de análise complexos que incorporem a atuação conjunta dos distintos fatores com potencial explicativo.

Throughout the first decade of the 2000s the homicide mortality rate (HMR) showed a significant reduction in the state and the city of São Paulo (MSP). The aim of this study is to describe the trend of HMR, socio-demographic indicators, and the investment in social and public security, and to analyze the correlation between HMR and independent variables in the MSP between 1996 and 2008. An exploratory time series ecological study was conducted. The following variables were included: HMR per 100,000 inhabitants, socio-demographic indicators, and investments in social and public security. The moving-averages for all variables were calculated and trends were analyzed through Simple Linear Regression models. Annual percentage changes, the average annual change and periodic percentage changes were calculated for all variables, and the associations between annual percentage changes were tested by Spearman's correlation analysis. Correlations were found for the proportion of youth in the population (r = 0.69), unemployment rate (r = 0.60), State budget for education and culture (r = 0.87) and health and sanitation (r = 0.56), municipal (r = 0.68) and State (r = 0.53) budget for Public Security, firearms seized (r = 0.69) and the incarceration rate (r = 0.71). The results allow us to support the hypothesis that demographic changes, acceleration of the economy, in particular the fall in unemployment, investment in social policies and changes in public security policies act synergistically to reduce HMR in São Paulo. Complex models of analysis, incorporating the joint action of different potential explanatory variables, should be developed.

OBJETIVO: Descrever a evolução da mortalidade por homicídios no Município de São Paulo segundo tipo de arma, sexo, raça ou cor, idade e áreas de exclusão/inclusão social entre 1996 e 2008. MÉTODOS: Estudo ecológico de série temporal. Os dados sobre óbitos ocorridos no Município foram coletados da base de dados do Programa de Aprimoramento das Informações sobre Mortalidade, seguindo a Classificação Internacional de Doenças, Décima Revisão (CID-10). Foram calculadas as taxas de mortalidade por homicídio (TMH) para a população total, por sexo, raça ou cor, faixa etária, tipo de arma e área de exclusão/inclusão social. As TMH foram padronizadas por idade pelo método direto. Foram calculados os percentuais de variação no período estudado. Para as áreas de exclusão/inclusão social foram calculados os riscos relativos de morte por homicídio. RESULTADOS: As TMH apresentaram queda de 73,7% entre 2001 e 2008. Foi observada redução da TMH em todos os grupos analisados, mais pronunciada em homens (-74,5%), jovens de 15 a 24 anos (-78,0%) e moradores de áreas de exclusão social extrema (-79,3%). A redução ocorreu, sobretudo, nos homicídios cometidos com armas de fogo (-74,1%). O risco relativo de morte por homicídio nas áreas de exclusão extrema (tendo como referência áreas com algum grau de exclusão social) foi de 2,77 em 1996, 3,9 em 2001 e 2,13 em 2008. Nas áreas de alta exclusão social, o risco relativo foi de 2,07 em 1996 e 1,96 em 2008. CONCLUSÕES: Para compreender a redução dos homicídios no Município, é importante considerar macrodeterminantes que atingem todo o Município e todos os subgrupos populacionais e microdeterminantes que atuam localmente, influenciando de forma diferenciada os homicídios com armas de fogo e os homicídios na população jovem, no sexo masculino e em residentes em áreas de alta exclusão social.

OBJECTIVE: To describe homicide mortality in the municipality of São Paulo according to type of weapon, sex, race or skin color, age, and areas of socioeconomic inequalities, between 1996 and 2008. METHOD: For this ecological time-series study, data about deaths in the municipality of São Paulo were collected from the municipal program for improvement of mortality information, using International Classification of Diseases, 10th revision (ICD-10) codes. Homicide mortality rates (HMR) were calculated for the overall population and specifically for each sex, race or skin color, age range, type of weapon, and occurrence in social deprivation/affluence areas. HMR were adjusted for age using the direct method. The percentage age of variation in HMR was calculated for the study period. For areas of socioeconomic inequalities, the relative risk of death from homicide was calculated. RESULTS: HMR fell 73.7% between 2001 and 2008. A reduction in HMR was observed in all groups, especially males (-74.5%), young men between 15 and 24 years of age (-78.0%), and residents in areas of extreme socioeconomic deprivation (-79.3%). The reduction occurred mostly in firearm homicide rates (-74.1%). The relative risk of death from homicide in areas of extreme socioeconomic deprivation, as compared to areas with some degree of socioeconomic deprivation, was 2.77 in 1996, 3.9 in 2001, and 2.13 in 2008. In areas of high socioeconomic deprivation, the relative risk was 2.07 in 1996 and 1.96 in 2008. CONCLUSIONS: To understand the reduction in homicide rates in the municipality of São Paulo, it is important to take into consideration macrodeterminants that affect the entire municipality and all population subgroups, as well as micro/local determinants that have special impact on homicides committed with firearms and on subgroups such as the young, males, and residents of areas of high socioeconomic deprivation.

Background: Urinary tract infection (UTI) is the most frequent bacterial infectious pathology during pregnancy. Efforts to accomplish an early detection and treatment are based on universal urine culture during pregnancy, study of etiologic agents and their susceptibility to antimicrobials prescripted during pregnancy. Objective: To describe the clinical and microbiological characteristics of cases of UTI in pregnant women attended in our institution during 2007 and compare them with the reports of 1988 and 2001. Methods: Clinical records of 112 pregnant women who presented UTI were reviewed, establishing the frequency of acute pyelonephritis (APN), infectious agent and antimicrobial susceptibility. Data were compared statistically with the records of 2001 and 1988 by calculating odds ratios. Results: The proportion of APN showed a decreasing trend between 1988, 2001 and 2007 (p<0.001). Escherichia coli was the most frequent infectious agent, although its frequency reduced between 2001 and 2007 (OR 0.32; IC95% 0.17-0.58). On the other hand, the frequency of UTI caused by Streptococcus agalactiae (GBS) increased during the same period of time (OR 3.98; 1.85-8.67). Antimicrobial susceptibility to ampicillin, gentamicin, nitrofurantoin y cotrimoxazole did not present significant differences between 2001-2007. Conclusion: A change in the clinical and microbiological characteristics of UTI in pregnant women was documented. The proportion of APN and UTI caused by Escherichia coli were reduced.

Antecedentes: La infección de tracto urinario (ITU) es la patología infecciosa bacteriana más frecuente del embarazo. Los esfuerzos por lograr una detección precoz y tratamiento adecuado se basan en la toma sistemática de urocultivo al inicio del embarazo, estudiando los agentes causales y la sensibilidad de éstos a los antibióticos recomendados durante la gestación. Objetivo: Describir los cuadros clínicos y microbio-lógicos de los casos de ITU registrados en embarazadas atendidas en nuestra institución durante el año 2007 y compararlos con los reportes de 1988 y 2001. Métodos: Se revisaron las historias clínicas de 112 embarazadas que cursaron ITU durante 2007, determinando la frecuencia de pielonefritis aguda (PNA), agente infeccioso y susceptibilidad a los antimicrobianos. Se compararon estos datos con los registrados en 2001 y 1988 mediante el cálculo de Odds Ratios. Resultados: La proporción de PNA mostró una tendencia decreciente entre 1988, 2001 y 2007 (p<0,001). Escherichia coli fue el agente infeccioso más frecuente, sin embargo, su frecuencia disminuyó entre 2001 y 2007 (OR 0,32; IC95% 0,17-0,58). Se observó un aumento de ITU por Streptococcus agalactiae (SGB) (OR 3,98; 1,85-8,67) durante igual período. La sensibilidad antimicrobiana a ampicilina, gentamicina, nitrofurantoina y cotrimoxazol no presentó diferencias significativas entre 2001-2007. Conclusión: Se documentó un cambio en el perfil clínico y microbiológico de las ITU en embarazadas, reduciéndose la proporción de PNA e ITU por Escherichia coli.
