Risco da síndrome da apneia obstrutiva do sono em amostra populacional da cidade de Botucatu - SP

The most common sleep disorder is obstructive sleep apnea syndrome (OSAS), that is characterized by repeated pauses in breathing during sleep, resulting in partial or complete obstruction of the upper airway. It is associated with systemic arterial hypertension and obesity. Objective: To assess the frequency of OSAS in the adult population of Botucatu by the Berlin questionnaire. Method: Transveral study was performed in which the sample size was estimated at 385 individuals. The Berlin questionnaire was administered to adults randomly on the streets, supermarkets and local shops. Data were analyzed taking into account age, gender, "high risk for OSAS", hypertension, obesity and correlations for OSAS. Results: 468 people interviewed were aged between 18 and 95 years, average of 59 years. 166 (35.25%) individuals were identified as "high risk for OSAS", being more frequent in the population above 40 years. Obesity was present in 23.3%, more common in women (60.2%). 83.5% of the population obese also had a "high risk for OSAS". Hypertension was observed in 27.3%, of these 71.9% were at "high risk for OSAS". Conclusion: The study showed a high frequency of "high risk for OSAS" in the adult population. Despite the dissemination by the media about sleep apnea, patients are not investigated, even under medical care for hypertension.

Notificações espontâneas de eventos adversos a medicamentos hospitalares: estudo piloto

Introduction: Post-marketing surveillance of drugs aims to detect problems related to safety, effectiveness and quality. The identification of adverse drug events (ADE) is made, mainly, by health professionals´ spontaneous reporting. This method allows risk communication in pharmacovigilance and contributes for market regulation. Objective: To estimate the prevalence of adverse drug reaction (ADR) and the suspicions of therapeutic failure (TF) reported by health professionals; to verify the active principle and type of drugs related to ADE, seriousness, causality, production mechanism and clinical manifestation of the events identified. METHODS: A cross-sectional study was performed in a teaching and public hospital which integrates the Sentinel Hospital Network, in 2008. ADR seriousness was classified according to intensity (mild, moderate, serious and lethal); drugs associated with ADE were categorized according to type (brand name drugs and non-brand name drugs); causality was imputed with Naranjo algorithm and the mechanism of occurrence was analyzed according to Rawlins e Thompson definitions (A or B). Results: There were 103 ADE reports in the period, of which 39 comprised TF and 64 ADR. Nurses reported the most ADE (53.4%). The majority of ADR were classified as type A (82.8%), mild (81.3%), possible (57.8%), according to causality assessment, and related to brand name drugs (20/35). Human immunoglobulin, docetaxel and paclitaxel were the drugs frequently associated with ADR. TF arising from no-brand name drugs (26/29), regarding, mainly, midazolam and ganciclovir. Conclusion: The results of the ADE report contribute for proposition of trigger tools for intensive monitoring of drug safety, as well as for the supplier qualification and for the improvement of quality products.

Medicamentos inadequados para idosos na estratégia da saúde da família

The ageing process can change the pharmacodynamics and pharmacokinetics parameters. Therefore, some medications are considered potentially inappropriate (PIM) for the elderly people, since they can increase the likelihood of occurrence of adverse drug events. The objectives are to estimate the frequency of use of PIM in the elderly people, with potentially hazardous drug interactions (PHDI) and to evaluate the impact of pharmaceutical intervention (PI) for the prescription of safer therapeutic alternatives. A cross-sectional study was performed in a Health Family Strategy (region of Araraquara, SP), between January and February/2012. The medical records of patients aged ≥60 years, that use at least one drug, were consulted for identification of PIM, according to the Beers criteria. The MPI identified were classified considering the Anatomical Therapeutic Chemical Classification System (ATC) and the essentiality of the drug (safety, effectiveness, quality and cost parameters) The inclusion criteria were met by 358 elderly, being that 93 of them (26%) had taken at least one PIM. Of the 114 different drugs prescribed for elderly, ten were classified as PIM, of which four of them act on the central nervous system, four on cardiovascular system and two on the digestive tract. Seven MPI are essential medicines, belonging to national list of essential drugs (RENAME-2010). Fourteen drug interactions were identified, of which two are PHDI (fluoxetine/amitriptyline and digoxin/hydrochlorothiazide).After the PI, there was no change in medical prescriptions of patients with PIM use or with DI. Medical prescriptions of elderly attended in the Health Family Strategy show pharmacotherapeutic safety problems, of which may be responsible for health hazardous for this age group. Although the intervention carried out by letter had been ineffective for the adherence of doctors in prescribing safe alternatives, wide dissemination of the lists that contain PIM and PHDI is need, as well as the inclusion of safer equivalents in RENAME, in order to contribute for rational use of drugs.

PREVALENCE AND DETERMINANTS OF EXCLUSIVE BREASTFEEDING IN THE CITY OF SERRANA, SAO PAULO, BRAZIL

The objective of this cross-sectional and quantitative study was to identify the prevalence and determinants of exclusive breastfeeding among infants less than six months of age in the city of Serrana, Sao Paulo, Brazil in 2009. A validated semi-structured questionnaire was administered to the guardians of the children less than six months of age who attended the second phase of a Brazilian vaccination campaign against polio. Univariate and multivariate analysis presented in odds ratios and confidence intervals was accomplished. Of the total of 275 infant participants, only 29.8% were exclusively breastfed. Univariate analysis revealed that mothers who work outside the home without maternity leave, mothers who did not work outside the home, adolescent mothers, and the use of pacifiers have a greater chance of interrupting exclusive breastfeeding. In the multivariate analysis, mothers who work outside the home without maternity leave are three times more likely to wean their children early. Results provide suggestions for the redirection and planning of interventions targeting breastfeeding.

THE ANALYSIS OF ACTIVITIES NOT PERFORMED BY THE NURSING TEAM REGARDING THE DIAGNOSIS OF INEFFECTIVE BREATHING PATTERN IN THE ELDERLY

The objective of this cross-sectional, descriptive study was to identify the activities of the Nursing Intervention Classification considered as priorities for an Ineffective Breathing Pattern and not performed for elderly inpatients of a teaching hospital in the state of Goias. The study participants were 43 nursing professionals, and data collection was performed in the period spanning October to December 2008, after receiving approval from the Ethics Committee. It was observed that among the 67 activities considered to be priorities for the referred diagnosis, only seven were performed by all of the participants; the other activities, with a varied frequency, were not performed, with the main reason cited being that a professional from a different area completed the activity. It is understood that the fact that the nursing staff does not perform these activities can cause lack of complete coverage in nursing care; therefore there is a need for a legal apparatus to describe the activities that comprise professional practice exclusive to nursing personnel and those activities that have an interdisciplinary nature.

Características e fatores associados às quedas atendidas em serviços de emergência

OBJETIVO: Analisar as características dos atendimentos decorrentes de quedas em serviços de urgência e emergência e identificar fatores associados. MÉTODOS: Estudo transversal com 12.617 atendimentos decorrentes de quedas registrados no Sistema de Vigilância de Violências e Acidentes, coletados em 23 capitais e Distrito Federal, de setembro a novembro de 2009, por meio de uma amostra por conglomerado. Foi utilizada a técnica de análise de correspondência, por permitir a observação conjunta de um grande número de variáveis qualitativas. RESULTADOS: A maior parte das vítimas foi do sexo masculino (56,5%), faixa etária de 0 a 19 anos (45,7%) e declarados não brancos (62,2%). A maioria das quedas ocorreu na residência (54,6%) e via pública (17,4%); 14,3% foram relacionadas ao trabalho. Os tipos predominantes foram "queda no mesmo nível" (57,0%) e "queda de escada/degrau" (15,6%). A maioria das lesões foi classificada como entorse, luxação, contusão, corte e laceração (68,3%). Quedas dentre as crianças associaram-se à ocorrência na residência; com os adolescentes na escola; e jovens na prática esportiva. Quedas em adultos estiveram associadas ao local de trabalho, queda de andaimes, telhados, escada/degrau e buracos e uso de álcool. As quedas no mesmo nível resultaram em lesões de menor gravidade, em membros inferiores e superiores, e as quedas de andaime e telhado se associaram com lesões de maior gravidade e internações. CONCLUSÕES: Os resultados mostram que estratégias para a prevenção das quedas devem ser implantadas particularmente em residências, escolas e ambientes de trabalho.

Body changes: antiretroviral therapy and lipodystrophy syndrome in people living with HIV/aids

Objective: to identify the different types of morphological alterations from lipodystrophy syndrome (LS) in outpatients and relate them to the therapeutic regimen used. Method: a cross-sectional study which recruited 60 patients with HIV and LS and 79 without LS, who consented to interview and data collection from their medical notes. Results: the region most affected by lipoatrophy was the face; by lipohypertrophy, the abdomen, and by the mixed form, the alterations to the abdomen, face, and upper and lower limbs. Conclusion: among the therapeutic regimens, that comprised of zidovudine, lamivudine and efavirenz seemed to protect against LS. Nursing can act in the early identification of the changes, as well as providing guidance and support for patients affected by the changes in their body image.

Transtorno afetivo bipolar: perfil farmacoterapêutico e adesão ao medicamento

This cross-sectional and descriptive study aimed to verify the adherence of patients with Bipolar Affective Disorder (BAD) to medication and to identify possible causes of adherence and non-adherence to medication according to the pharmacotherapeutic profile. The study was carried out in a mental health service in a city in the interior of the state of Sao Paulo. Participants included 101 patients with BAD. Structured interviews and the Morisky-Green test were used for data collection, and the Statistical Package for Social Science was employed for data analysis. Most subjects (63%) did not adhere to medication. Although there were no significant differences between the adherent and non-adherent groups for the researched variables, the use of polypharmacotherapy and complex treatment regimens was observed in treatment for BAD. In practice, implementing strategies to improve the adherence of patients to medication treatment remains a challenge.

Fatores maternos e neonatais associados ao mecônio no líquido amniótico em um centro de parto normal

OBJETIVO: Analisar a frequência e os fatores maternos e neonatais associados ao mecônio no líquido amniótico no parto. MÉTODOS: Estudo transversal com 2.441 nascimentos em um centro de parto normal hospitalar em São Paulo, SP, em março e abril de 2005. A associação entre mecônio no líquido amniótico e as variáveis independentes (idade materna, paridade, ter ou não cesariana prévia, idade gestacional, antecedentes obstétricos, uso de ocitocina no trabalho de parto, dilatação cervical na admissão, tipo do parto atual, peso do RN, índice de Apgar de 1º e 5º minutos de vida) foi expressa como razão de prevalência. RESULTADOS: Verificou-se mecônio no líquido amniótico em 11,9% dos partos; 68,2% desses foram normais e 38,8%, cesarianas. O mecônio esteve associado a: primiparidade (RP = 1,49; IC95% 1,29;1,73), idade gestacional ≥ 41 semanas (RP = 5,05; IC95% 1,93;13,25), ocitocina no parto (RP = 1,83, IC95% 1,60;2,10), cesariana (RP = 2,65; IC95% 2,17;3,24) e índice de Apgar < 7 no 5º minuto (RP = 2,96, IC95% 2,94;2,99). A mortalidade neonatal foi 1,6/1.000 nascidos vivos; mecônio no líquido amniótico foi encontrado em 50% das mortes neonatais e associado a maiores taxas de partos cirúrgicos. CONCLUSÕES: Emprego de ocitocina, piores condições do recém-nascido logo após o parto e aumento de taxas de cesariana foram fatores associados ao mecônio. A utilização rotineira de ocitocina no intraparto poderia ser revista por sua associação com mecônio no líquido amniótico.

Avaliação dos registros de enfermagem sobre ressuscitação cardiopulmonar baseada no modelo Utstein

Estudo transversal que avaliou a qualidade dos registros de enfermagem sobre ressuscitação cardiopulmonar. Foram revisados 42 prontuários de pacientes em uma unidade de terapia intensiva, utilizando o protocolo Utstein. Houve predomínio de homens (54,8%), idade de 21 a 70 anos (38,1%), correção de cardiopatias adquiridas (42,7%), com mais de um dispositivo pré-existente (147). Como causa imediata de parada cardiorrespiratória, predominou hipotensão (48,3%) e como ritmo inicial, bradicardia (37,5%). Apenas a hora do óbito e hora da parada foram registradas em 100% da amostra. Não foi registrado treinamento dos profissionais em Suporte Avançado de Vida. As causas da parada e ritmo inicial foram registrados em 69% e 76,2% da amostra. Compressões torácicas, obtenção de vias aéreas pérvias e desfibrilação foram registradas em menos de 16%. Os registros foram considerados de baixa qualidade, podendo incorrer em sanções legais aos profissionais e não permitindo a comparação da efetividade das manobras com outros centros.

La muda de la voz en niños cantores y no cantores : análisis de la rotura de registros

La mayor parte de los estudios sobre la mutación vocal se ha focalizado sobre las variaciones de la frecuencia fundamental del habla en relación con la edad, el peso, la altura, el vello axilar y pubiano y el nivel de testosterona en sangre. Los maestros de canto y los vocólogos que trabajan con voces infantiles, ya sean cantadas o habladas, deberían conocer profundamente las características de la mutación vocal. Con esa finalidad, llevamos a cabo un estudio de seguimiento longitudinal de 18 niños (9 cantores y 9 no cantores) durante 18 meses. Efectuamos,además, un estudio transversal por rangos de edad a 98 niños y jóvenes. Todos los sujetos fueron examinados a través de un examen perceptual y de un examen acústico luego de un examen ORL normal. Los resultados muestran que las roturas de registro desde el falsete al modal, a través de la producción de un glissando descendente, son el signo más importante de mutación desde un punto de vista perceptual. Estas roturas son independientes del entrenamiento vocal y ocurren tanto en cantores como en no cantores de la misma manera. Las roturas de registro determinan otra serie de características como el estrechamiento del rango fonacional, las roturas de voz y el descenso excesivo de la frecuencia fundamental del habla. Las roturas de registro producidas a través de un glissando descendente son muy llamativas durante el período crítico de mutación. No aparecen en las voces infantiles ni en las voces adultas saludables, sean estas voces con o sin entrenamiento. La mutación vocal de los niños varones atraviesa los siguientes estadíos: período pre-mutacional, comienzos de mutación, período crítico y período fi nal; cada estadio evidencia sus características distintivas tanto desde el punto de vista perceptual como acústico.

La analgesia aplicada figuraba en historia clínica en 40.29%, en indicaciones para enfermería 82.73%. La valoración del dolor fue registrada en 46.76% de las evoluciones diarias.

Autopercepción del cuerpo y estado nutricional en población escolar de la ciudad de La Plata

El objetivo es indagar la relación entre el estado nutricional (EN) y su percepción por parte de niños de 2o ciclo de nivel primario en función de la edad. Asimismo, a fin de identificar su incidencia, se observó el desenvolvimiento de los mismos en las clases de Educación Física (EF). Población y Métodos: 160 escolares de 9 a 13 años de una escuela privada de La Plata. Estudio transversal, descriptivo y analítico. Los datos se obtuvieron a través de una encuesta ad hoc, anónima, autoadministrada con acompañamiento y a través de observaciones de las clases de EF. Se evaluó el EN calculando el Indice de Masa Corporal. Los datos fueron procesados con el SPSS. Resultados: El 47 por ciento de los niños tiene normopeso (N), el 25 por ciento sobrepeso (S) y el 28 por ciento obesidad (O). El 72,5 por ciento y 73 por ciento de los niños con S y O respectivamente desearían ser más delgados. Lo mismo opina el 43 por ciento con N. En 5o y 6o año la proporción de niños disconformes con su peso es significativamente mayor que el grupo de menor edad. Dicha proporción supera el porcentaje de los que tienen exceso de peso. Las observaciones corroboran que los niños más grandes se preocupan más por la apariencia y tienen más inhibiciones. Conclusión: La incidencia de S y O en la población escolar estudiada es muy alta. La mayoría de los niños con exceso de peso y casi la mitad con N desearían ser más delgados. Los niños de 4o son los que tienen mayor S y O, pero son los de 5o y 6o los que en mayor proporción expresan disconformidad con su peso

Actividad física y estado nutricional en escolares del nivel primario de la ciudad de La Plata

Según la Organización Mundial de la Salud (OMS), los niños deberían acumular diariamente al menos 60 min. de AF para garantizar un desarrollo saludable. El objetivo es indagar sobre el tiempo dedicado a la AF (escolar y extra-escolar) y su relación con el EN. Población y Métodos: 302 niños de 9 a 13 años. Estudio transversal, descriptivo y analítico, llevado a cabo en 3 escuelas de La Plata. Se evaluó el EN calculando en Indice de Masa Corporal. Los datos se obtuvieron a través de una encuesta ad hoc, anónima, autoadministrada con acompañamiento y fueron procesados con el SPSS. Resultados: El 49 por ciento de los niños tiene normopeso (N), el 25 por ciento Sobrepeso (S) y el 26 por ciento obesidad (O). El 84 por ciento participa "Siempre" de las clases de EF, y el 16 por ciento lo hace "A veces". El 91 por ciento de los N y el 77 por ciento de los niños con S y O participan siempre (p=0,006). El 26 por ciento y el 18 por ciento de los niños con S y O respectivamente alegan razones negativas a al grado de participación en la clase de EF. Respecto de la AFEE, el 42 por ciento de los niños no acumula el tiempo de AF recomendado por la OMS. Al sumar la clase de EF a la AFEE este porcentaje decrece un 10 por ciento. Conclusiones: El S y O en niños es muy alto. Los niños con exceso de peso participan con menos frecuencia de las clases de EF y alegan en mayor proporción, motivos negativos para fundamentar tal participación. La clase de EF incide en un incremento del 10 por ciento de casos que cumplen con el tiempo recomendado de actividad física
