Compromiso pulmonar en pacientes hospitalizados con infección por el virus de inmunodeficiencia humana en el Hospital Pablo Tobón Uribe (Medellín, Colombia) / Pulmonary compromise in inpatients with human immunodeficiency virus infection at Pablo Tobón Uribe Hospital, Medellín, Colombia

Más de la mitad de los pacientes con infección por virus de inmunodeficiencia humana (VIH) pueden tener compromiso pulmonar en el transcurso de su vida. Este puede ser multicausal y las infecciones oportunistas son las principales, sin embargo, las causas no infecciosas no son menos importantes. Objetivo: Describir las características del compromiso pulmonar en pacientes hospitalizados con infección por VIH. Metodología: Estudio descriptivo observacional. Resultados: Se incluyó a 63 pacientes, el 85,7% fueron hombres. La edad promedio fue 40,6 ± 12 años. El 21,4% tuvieron antecedente de promiscuidad sexual y 28,6% fueron hombres con sexo con hombres. Se identificó tabaquismo en 60,3%, alcoholismo en 52,4% y consumo de drogas en 20,6%. El 23,8% tuvo historia de tuberculosis. Al ingreso, el 79,4% tenía sida, el recuento promedio de CD4 fue 138,5 ± 17,7 células/mm3 y el 49,2% tenía CD4 < 100 células/mm3. Las principales comorbilidades fueron: enfermedad neoplásica 20,6%, diarrea crónica 19%, EPOC 6,3% y diabetes mellitus 3,2%. Los principales síntomas al ingreso fueron: respiratorios 66,7%, gastrointestinales 47,6% y neurológicos 34,9%. Los principales oportunistas documentados fueron Mycobacterium spp, H. capsulatum y P. jirovecii. El sarcoma de Kaposi, la enfermedad lifoproliferativa y la EPOC fueron causas de compromiso no infeccioso. Los principales hallazgos radiográficos fueron: infiltrados intersticiales (42,9%), compromiso pleural (23,8%) y lesiones cavitarias (7,9%). El compromiso multilobar fue evidente en el 15,9%. Las principales complicaciones fueron falla respiratoria, disfunción orgánica múltiple y falla renal aguda. El 19% requirió ingreso a UCI y, de estos, el 83,3% necesitó ventilación mecánica. La estancia hospitalariapromedio fue de 18 ± 20 días y la mortalidad del 17,5%. Discusión: Las infecciones por oportunistas son las principales causas de compromiso pulmonar y, dentro de estas, las causadas por micobacterias. Puede ocurrir más de una infección oportunista simultáneamente, pero en nuestra población fueron infrecuentes. Las causas noinfecciosas también son importantes.

More than a half of patients with HIV infection have pulmonary involvement throug-hout their lives. Opportunistic infections are the main cause; however, many patients havenoninfectious pulmonary involvement. Objective: To describe the characteristics of pulmonary involvement in inpatients with HIVinfection.Methods: Descriptive observational study. Results: A total of 63 patients were included, and 85.7% were men. The average age was40.6 ± 12 years. Some 21.4% had a history of sexual promiscuity and 28.6% were men whohad sex with men. Smoking was found in 60.3%, alcoholism in 52.4% and drug abuse in 20.6%.A tuberculosis history was documented in 23.8% of patients. At admission, 79.4% had AIDS, themean CD4 count was 138.5 ± 17.7 cells/mm3and 49.2% had CD4 counts < 100 cells/mm3. Majorcomorbidities included neoplastic disease in 20.6%, chronic diarrhea in 19%, COPD in 6.3% anddiabetes in 3.2%. Major opportunistic agents were Mycobacterium spp, H. capsulatum and P.jirovecii. Kaposi's sarcoma, lymphoproliferative disease and COPD were causes of noninfectiouspulmonary involvement. The main radiographic findings included interstitial infiltrates in 42.9%,pleural involvement in 23.8%, alveolar infiltrates in 7.9% and cavitary lesions in 7.9%. Multilobarcompromise was evident in 15.9% of the patients. The major complications were respiratoryfailure, multiple organ dysfunction and acute renal failure. Some 19% required care in the ICUand 83.3% of these required mechanical ventilation. The mean stay was 18 ± 20 days and themortality was 17.5%. Discussion: Opportunistic infections are the main causes of lung involvement and mycobacterialdiseases were most frequent. Mycobacterial diseases can occur simultaneously with an oppor-tunistic infection, but in our series this was infrequent. Non-infectious diseases are importantbut are less common.

Fatores associados ao consumo de bebidas açucaradas entre pré-escolares brasileiros: inquérito nacional de 2006 / Factors associated with the consumption of soft drinks among Brazilian preschool children: national survey of 2006

Resumo O crescente consumo de bebidas açucaradas como os refrigerantes ou sucos artificiais está associado à prevalência de obesidade no Brasil e no mundo. Este estudo se propõe a conhecer a frequência de consumo destas bebidas entre crianças brasileiras de 24 a 59 meses e investigar associações com variáveis demográficas, socioeconômicas e nutricionais. Utilizando dados da Pesquisa Nacional de Demografia e Saúde da Criança e da Mulher − 2006, o padrão alimentar foi obtido com o questionário de frequência de alimentos e bebidas nos sete dias anteriores à data da entrevista e a antropometria usou medidas de peso e de estatura das crianças. Entre os pré-escolares, 37,3% consumiram refrigerantes e sucos artificiais 4 dias ou mais por semana. Os fatores que apresentaram associação estatisticamente significante com consumo frequente de BA foram residir em regiões de maior desenvolvimento econômico do país, em áreas urbanas, pertencer ao estrato de maior poder aquisitivo, mães que assistiam TV regularmente e excesso de peso da criança, estavam associados ao consumo de refrigerantes e sucos artificiais em 4 ou mais dias por semana. Novos estudos são necessários para a compreensão da real contribuição das bebidas açucaradas na epidemia de obesidade infantil.

Abstract The rising consumption of sweetened beverages such as soft drinks or artificial juices is associated with the prevalence of obesity in Brazil and around the world. This study seeks to verify the frequency of consumption of these beverages among Brazilian children aged 24-59 months and to investigate the association of soft drinks with demographic, socioeconomic and nutritional variables. Using data from the National Survey on Demography and Health of Women and Children − 2006, the eating habits were obtained using the food and drink frequency questionnaire for the seven days preceding the interview, and anthropometry recorded the weight and height of children. Among preschoolers, 37.3% consumed soft drinks and artificial juices 4 or more days per week. The factors significantly associated with frequent consumption of soft drinks were living in regions of higher economic development of the country, in urban areas, belonging to the higher income bracket, with mothers watching TV regularly and excess weight of the child, were associated with consumption of soft drinks and artificial juices 4 or more days per week. Further studies are needed to understand the effective contribution of soft drinks on the epidemic of childhood obesity.

Características sociodemográficas e nutricionais de crianças brasileiras menores de 2 anos beneficiárias de programas de transferência condicionada de renda em 2006 / Socio-demographic and nutritional characteristics of Brazilian children under 2 years of age who were beneficiaries of conditional cash transfer programs in 2006

Programas de transferência condicionada de renda (PTCR) visam o combate à pobreza e à fome e a garantia da segurança alimentar. Crianças menores de 2 anos de famílias beneficiárias são mais vulneráveis às condições ambientais. Este estudo objetiva caracterizar esta população segundo variáveis socioeconômicas, demográficas e nutricionais. Utilizaram-se dados secundários da Pesquisa Nacional de Demografia e Saúde da Crian ça e da Mulher (PNDS-2006). Descreveram-se os dados em média e desvios-padrão. Para as associações utilizou-se o teste qui-quadrado e intervalos de confiança de 95%. Das 1735 crianças 29,4% eram beneficiárias de PTCR com renda média familiar de R$430,20 e valor médio dos benefícios de R$75. Dentre as que residiam no Nordeste ou na região rural do país, uma em cada três recebiam PTCR. Entre as que viviam em insegurança alimentar grave, 52,3% pertenciam a PTCR. Classes econômicas D e E e baixa escolaridade materna associaram-se a PTCR. Entre os desvios nutricionais das crianças beneficiárias, prevaleceu o peso elevado para idade. Das que interromperam o aleitamento materno exclusivo antes dos dois meses, 31,2% eram de PTCR. Identifica-se a necessidade de educação nutricional preventiva a fim de otimizar a utilização do benefício.

The conditional cash transfer programs (PTCR) seek to combat poverty and hunger and to ensure food security. Children under the age of two of beneficiary families are more vulnerable to environmental conditions. This study seeks to describe this population according to socio-economic, demographic and nutritional variables. Secondary data from the National Survey on Demography and Health of Women and Children (PNDS-2006) were used. Data were described using mean and standard deviations. Associations were described using the chi-square test with confidence intervals of 95%. Of the 1735 children, 29.4% were PCTR beneficiaries with average family income of R$430.20 and average benefits of R$75. Among those living in the Northeast or in the rural area of the country, one in every three received benefits. Among those experiencing severe food insecurity, 52.3% were PTCR beneficiaries. Children from socio-economic classes D and E and whose mothers had less than four years education were associated with PTCR. Among the nutritional disorders of child beneficiaries, overweight for age prevailed. Of those who ceased exclusive breastfeeding in less than two months, 31.2% were beneficiaries. The need for preventive nutritional education was identified in order to optimize the use of benefits.

Puntaje de riesgo para morbilidad y mortalidad en pacientes sometidos a intervencionismo coronario percutáneo / Morbimortality risk score in patients submitted to percutaneous coronary intervention

El objetivo principal de este estudio observacional, fue establecer un puntaje de riesgo para morbilidad y mortalidad intrahospitalaria en pacientes sometidos a intervención coronaria percutánea luego de sufrir alguno de los siguientes síndromes coronarios agudos: angina inestable, infarto agudo del miocardio sin elevación del segmento ST o infarto agudo del miocardio con elevación del segmento ST. Se realizó una recolección de datos clínicos y demográficos a partir de 1.310 pacientes atendidos en la clínica, entre 2003 a 2006, de manera retro-prospectiva, con el fin de elaborar un puntaje válido para la población colombiana. Esto se realizó mediante una base de datos de múltiples variables pre-procedimiento (antecedentes personales), variables intra-procedimiento (tiempo transcurrido desde la hora de la consulta al servicio de urgencias hasta el momento del cateterismo, número de vasos enfermos entre otros) y variables post-procedimientos (complicaciones de morbi-mortalidad). Luego, el análisis de los datos se llevó a cabo mediante un modelo de regresión logística, para determinar cuáles de los factores de riesgo fueron estadísticamente significativos para causar alguno de los resultados evaluados. Los principales resultados evaluados fueron: muerte, eventos hematológicos adversos y estancia hospitalaria. Luego del análisis se encontró que los principales factores relacionados con la morbi-mortalidad de los pacientes fueron el tipo de paciente (o tipo de síndrome coronario sufrido), su edad y su estado hemodinámico al ingreso (presencia de shock cardiogénico). A partir de estos resultados, se desarrolló el puntaje de riesgo a través de las variables pre-operatorias e intra-operatorias.
