Retrospective Study of the Survival of Patients who Underwent Cardiopulmonary Resuscitation in an Intensive Care Unit

OBJECTIVE: To evaluate clinical and evolutive characteristics of patients admitted in an intensive care unit after cardiopulmonary resuscitation, identifying prognostic survival factors.METHODS: A retrospective study of 136 patients admitted between 1995 and 1999 to an intensive care unit, evaluating clinical conditions, mechanisms and causes of cardiopulmonary arrest, and their relation to hospital mortality.RESULTS: A 76% mortality rate independent of age and sex was observed. Asystole was the most frequent mechanism of death, and seen in isolation pulmonary arrest was the least frequent. Cardiac failure, need for mechanical ventilation, cirrhosis and previous stroke were clinically significant (p<0.01) death factors.CONCLUSION: Prognostic factors supplement the doctor's decision as to whether or not a patient will benefit from cardiopulmonary resuscitation.

Detección de circovirus pocino tipo II en cerdos que presentan diarrea en criaderos intensivos. Detection of porcine circovirus type II in pigs that present diarrhea in intensive hatcheries.

Se propone detectar la presencia del agente etiológico circovirus porcino (CVP) en cerdos con diarrea. El cual se considera un patógeno emergente importante asociado a diferentes sindromes y enfermedades porcinas. Se comunicó a nivel internacional en 1997 y en Argentina fue descripto en el 2003 en animales de cria extensiva, aunque se encuentra en los diferentes sistemas de producción. Su presencia causa grandes pérdidas económicas, ya que muchas veces no tiene una sintomatología clínica, sino que se manifiesta subclinicamente. En la provincia de Córdoba no se han realizado estudios sistemáticos para determinar la presencia de circovirus. Además, en animales que presentan diarrea no se ha realizado un relevamiento de la presencia del CVP y su asociación con el cuadro clínico. Diversos investigadores estan viendo la necesidad de incluir al CVP a la hora de pensar en los diagnósticos etiológicos, en aquellos que no solo presentan índices productivos ineficientes sino también que no responden a la terapia antimicrobiana. Es agente causal del Sindrome de Desmedro Posdestete y podria favorecer la acción de otros agentes patógenos que actuarían tanto en Sistema Respirastorio como en Sistema Digestivo. La complejidad del trabajo radica en demostrar lo antes mencionado a traves de las lesiones a observar en los tejidos y la determinación de la presencia del agente. La ejecución de este estudio sería un importante aporte a la producción porcina, en donde este agente produce importantes pérdidas económicas. La metodología, así como los resultados obtenidos serán útiles en la formación de recursos humanos aplicados a la investigación y transferidos directamente a la docencia. Hipotesis: Establecer la presencia del CVP en cerdos con signos clinicos de enteropatías Objetivos: Determinar en cortes histopatológicos de intestino y ganglio mesentério, lesiones compatibles con CVP; Determinar por inmunohistoquímica la presencia del antígeno CVP en las muestras. Identificar las células en las que se encuentre el antígeno. Materiales y método: Muestreo a campo y toma de muestra. En diferentes establecimientos porcinos, de aquellos animales que presenten el cuadro clínico de diarrea, serán elegidos 3 animales aleatoriamente para sacrificio y realización de la técnica de necropsia. Se tomarán muestras de intestino delgado y ganglio mesentérico que serán fijadas en formol; la técnica histopatológica y su lectura tendrán fin de encontrar lesiones compatibles con circovirus porcino tipo II; Realización de la técnica de inmunohistoquímica con anticuerpo monoclonal, para la detección del CVP en los tejidos; Interpretación de resultados; Publicación de los resultados.

Blood Pressure Control in Hypertensive Patients in the "Hiperdia Program": A Territory-Based Study

Background:Systemic hypertension is highly prevalent and an important risk factor for cardiovascular events. Blood pressure control in hypertensive patients enrolled in the Hiperdia Program, a program of the Single Health System for the follow-up and monitoring of hypertensive patients, is still far below the desired level.Objective:To describe the epidemiological profile and to assess blood pressure control of patients enrolled in Hiperdia, in the city of Novo Hamburgo (State of Rio Grande do Sul, Brazil).Methods:Cross-sectional study with a stratified cluster random sample, including 383 adults enrolled in the Hiperdia Program of the 15 Basic Health Units of the city of Porto Alegre, conducted between 2010 and 2011. Controlled blood pressure was defined as ≤140 mmHg × 90 mmHg. The hypertensive patients were interviewed and their blood pressure was measured using a calibrated aneroid device. Prevalence ratios (PR) with 95% confidence interval, Wald's χ2 test, and simple and multiple Poisson regression were used in the statistical analysis.Results:The mean age was 63 ± 10 years, and most of the patients were females belonging to social class C, with a low level of education, a sedentary lifestyle, and family history positive for systemic hypertension. Diabetes mellitus (DM) was observed in 31%; adherence to the antihypertensive treatment in 54.3%; and 33.7% had their blood pressure controlled. DM was strongly associated with inadequate BP control, with only 15.7% of the diabetics showing BP considered as controlled.Conclusion:Even for hypertensive patients enrolled in the Hiperdia Program, BP control is not satisfactorily reached or sustained. Diabetic hypertensive patients show the most inappropriate BP control.

Impact of Intensive Physiotherapy on Cognitive Function after Coronary Artery Bypass Graft Surgery

Background: Coronary artery bypass graft (CABG) is a standard surgical option for patients with diffuse and significant arterial plaque. This procedure, however, is not free of postoperative complications, especially pulmonary and cognitive disorders. Objective: This study aimed at comparing the impact of two different physiotherapy treatment approaches on pulmonary and cognitive function of patients undergoing CABG. Methods: Neuropsychological and pulmonary function tests were applied, prior to and following CABG, to 39 patients randomized into two groups as follows: Group 1 (control) - 20 patients underwent one physiotherapy session daily; and Group 2 (intensive physiotherapy) - 19 patients underwent three physiotherapy sessions daily during the recovery phase at the hospital. Non-paired and paired Student t tests were used to compare continuous variables. Variables without normal distribution were compared between groups by using Mann-Whitney test, and, within the same group at different times, by using Wilcoxon test. The chi-square test assessed differences of categorical variables. Statistical tests with a p value ≤ 0.05 were considered significant. Results: Changes in pulmonary function were not significantly different between the groups. However, while Group 2 patients showed no decline in their neurocognitive function, Group 1 patients showed a decline in their cognitive functions (P ≤ 0.01). Conclusion: Those results highlight the importance of physiotherapy after CABG and support the implementation of multiple sessions per day, providing patients with better psychosocial conditions and less morbidity.

Blood Pressure and Hemodynamic Adaptations after a Training Program in Young Individuals with Down Syndrome

Background:Cardiovascular diseases affect people worldwide. Individuals with Down Syndrome (DS) have an up to sixteen-time greater risk of mortality from cardiovascular diseases.Objective:To evaluate the effects of aerobic and resistance exercises on blood pressure and hemodynamic variables of young individuals with DS.Methods:A total of 29 young individuals with DS participated in the study. They were divided into two groups: aerobic training (AT) (n = 14), and resistance training (TR) (n = 15). Their mean age was 15.7 ± 2.82 years. The training program lasted 12 weeks, and had a frequency of three times a week for AT and twice a week for RT. AT was performed in treadmill/ bicycle ergometer, at an intensity between 50%-70% of the HR reserve. RT comprised nine exercises with three sets of 12 repetition-maximum. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP) and hemodynamic variables were assessed beat-to-beat using the Finometer device before/after the training program. Descriptive analysis, the Shapiro-Wilk test to check the normality of data, and the two-way ANOVA for repeated measures were used to compare pre- and post-training variables. The Pearson’s correlation coefficient was calculated to correlate hemodynamic variables. The SPSS version 18.0 was used with the significance level set at p < 0.05.Results:After twelve weeks of aerobic and/or resistance training, significant reductions in variables SBP, DBP and MBP were observed.Conclusion:This study suggests a chronic hypotensive effect of moderate aerobic and resistance exercises on young individuals with DS.
