Understanding the experiences of caregivers of children with tuberculosis in directly observed therapy

Objective To understand the situations and communications experienced by caregivers of children with tuberculosis (TB) with regard to directly observed therapy (DOT). Method A descriptive exploratory study with a qualitative approach was applied and developed in the ambulatory of Programa Einstein na Comunidade de Paraisópolis (PECP). The data were collected using semi-structured interviews of 13 caregivers of children with TB in DOT. The Collective Subject Discourse (CSD) method was used to analyze the data. Results Seven CSDs were identified and grouped into four categories: "Living in a difficult situation", "Changing the family routine", "Responsibility almost always fall son the mother", and "Adapting to the DOT". Conclusions The difficulties faced by the caregiver of the child at the beginning of DOT significantly changed the familiar routine. The responsibility for its continuity was assigned to the mother, who must adapt to the demands of the treatment and face the situation.

Evaluation of professional knowledge and attitudes on dementia patient care: a trans-cultural adaptation of an evaluation instrument

Objective To describe the trans-cultural adaptation of the evaluation instrument entitled Atenció Sanitària de Les Demències: la visió de L' Atenció Primarià from Catalan into versions in Portuguese for doctors and nurses. This study evaluates the knowledge and perspectives of these professionals in their treatment of patients diagnosed with dementia in cases of primary care. Method The adaptation followed internationally accepted rules, which include the following steps: translation, synthesis, back-translation, revision by a committee of specialists, and a test run with 35 practicing doctors and 35 practicing nurses in Brazil's Family Health Strategy (Estratégia Saúde da Família, or ESF in Portuguese). Results The translation, synthesis, and back-translation steps were performed satisfactorily; only small adjustments were required. The committee of specialists verified the face validity in the version translated into Portuguese, and all of the items that received an agreement score lower than 80% during the initial evaluation were revised. In the test run, the difficulties presented by the health care professionals did not reach 15% of the sample, and therefore, no changes were made. Conclusion The Portuguese translation of the instrument can be considered semantically, idiomatically, culturally, and conceptually equivalent to the original Catalan version and is, therefore, appropriate for use in Brazil.

Cardiac Function Assessed by Transesophageal Echocardiography During Pectus Excavatum Repair

Background. We assessed end-diastolic right ventricular (RV) dimensions and left ventricular (LV) ejection fraction by use of intraoperative transesophageal echocardiography before and after surgical correction of pectus excavatum in adults. Methods. A prospective study was conducted including 17 patients undergoing surgical correction of pectus excavatum according to the technique of Ravitch-Shamberger between 1999 and 2004. Intraoperative transesophageal echocardiography was performed under general anesthesia before and after surgery to assess end-diastolic RV dimensions and LV ejection fraction. The end-diastolic RV diameter and area were measured in four-chamber and RV inflow-outflow view, and the RV volume was calculated from these data. The LV was assessed by transgastric short-axis view, and its ejection fraction was calculated by use of the Teichholz formula. Results. The end-diastolic RV diameter, area, and volume all significantly increased after surgery (mean values +/- SD, respectively: 2.4 +/- 0.8 cm versus 3.0 +/- 0.9 cm, p < 0.001; 12.5 +/- 5.2 cm(2) versus 18.4 +/- 7.5 cm(2), p < 0.001; and 21.7 +/- 11.7 mL versus 40.8 +/- 23 mL, p < 0.001). The LV ejection fraction also significantly increased after surgery (58.4% +/- 15% versus 66.2% +/- 6%, p < 0.001). Conclusions. Surgical correction of pectus excavatum according to Ravitch-Shamberger technique results in a significant increase in end-diastolic RV dimensions and a significantly increased LV ejection fraction.

Biodiversidade de moscas-das-frutas do gênero Anastrepha (Diptera, Tephritidae) no campus da ESALQ-USP, Piracicaba, São Paulo

Este trabalho foi conduzido na área abrangida pelo campus da Escola Superior de Agricultura Luiz de Queiroz da Universidade de São Paulo, no município de Piracicaba, Estado de São Paulo. Teve como objetivos, determinar a composição do gênero Anastrepha Schiner e verificar a associação das espécies de plantas hospedeiras, estabelecidas na área, com as espécies de Anastrepha. Foram examinadas 23.277 fêmeas de Anastrepha coletadas por meio de armadilhas McPhail e 18 espécies pertencentes a nove grupos de espécies foram registradas. Um total de 563 amostras de frutos pertencentes a nove famílias e, pelo menos, 23 espécies de plantas foi coletado em 47 estações de capturas. Foram identificadas 10.243 fêmeas e das 18 espécies de Anastrepha capturadas em armadilhas somente seis emergiram das amostras de frutos: A. bistrigata Bezzi, A. fraterculus (Wied.), A. obliqua (Macquart), A. pseudoparallela (Loew), A. serpentina (Wied.) e A. sororcula Zucchi. A. fraterculus infestou maior diversidade de frutos. Os hospedeiros preferidos de A. obliqua foram as espécies da família Anacardiaceae. A. pseudoparallela e A. serpentina infestaram exclusivamente Passifloraceae e Sapotaceae, respectivamente. A. fraterculus é registrada pela primeira vez em sapoti (Manilkara zapota L.) no Brasil.

Severe stroke: patient profile and predictors of favorable outcome.

Summary.  Background:  Severe stroke carries high rates of mortality and morbidity. The aims of this study were to determine the characteristics of patients who initially presented with severe ischemic stroke, and to identify acute and subacute predictors of favorable clinical outcome in these patients. Methods:  An observational cohort study, Acute Stroke Registry and Analysis of Lausanne (ASTRAL), was analyzed, and all patients presenting with severe stroke - defined as a National Institute of Health Stroke Scale score of ≥ 20 on admission - were compared with all other patients. In a multivariate analysis, associations with demographic, clinical, pathophysiologic, metabolic and neuroimaging factors were determined. Furthermore, we analyzed predictors of favorable outcome (modified Rankin scale score of ≤ 3 at 3 months) in the subgroup of severe stroke patients. Results:  Of 1915 consecutive patients, 243 (12.7%) presented with severe stroke. This was significantly associated with cardio-embolic stroke mechanism (odds ratio [OR] 1.74, 95% confidence interval [CI] 1.19-2.54), unknown stroke onset (OR 2.35, 95% CI 1.14-4.83), more neuroimaging signs of early ischemia (mostly computed tomography; OR 2.65, 95% CI 1.79-3.92), arterial occlusions on acute imaging (OR 27.01, 95% CI 11.5-62.9), fewer chronic radiologic infarcts (OR 0.43, 95% CI 0.26-0.72), lower hemoglobin concentration (OR 0.97, 95% CI 0.96-0.99), and higher white cell count (OR 1.05, 95% CI 1.00-1.11). In the 68 (28%) patients with favorable outcomes despite presenting with severe stroke, this was predicted by lower age (OR 0.94, 95% CI 0.92-0.97), preceding cerebrovascular events (OR 3.00, 95% CI 1.01-8.97), hypolipemic pretreatment (OR 3.82, 95% CI 1.34-10.90), lower acute temperature (OR 0.43, 95% CI 0.23-0.78), lower subacute glucose concentration (OR 0.74, 95% CI 0.56-0.97), and spontaneous or treatment-induced recanalization (OR 4.51, 95% CI 1.96-10.41). Conclusions:  Severe stroke presentation is predicted by multiple clinical, radiologic and metabolic variables, several of which are modifiable. Predictors in the 28% of patients with favorable outcome despite presenting with severe stroke include hypolipemic pretreatment, lower acute temperature, lower glucose levels at 24 h, and arterial recanalization.
