Meta-analysis of effectiveness of community-based interventions in improving physical activity in youth with intellectual disability

Background and Objectives@#The effects of home or community-based interventions in increasing physical activity in youth with intellectual disabilities are yet to be known. Such information is important in designing the care for this population because of their increased susceptibility to lifestyle diseases that affect their quality of life. This study aimed to determine the effectiveness of home or community-based interventions in increasing physical activity levels in youth with intellectual disabilities. @*Methodology@#Eight databases were searched to identify intervention studies available in English that investigated the effects of home or community-based interventions on physical activity levels in youth with intellectual disabilities. Data were analyzed using descriptive statistics and meta-analysis using a random effects model. Effect sizes were calculated as standardized mean differences with 95% confidence intervals. @*Results@#Six randomized controlled trials were included in this review. Home or community-based interventions had a small effect in improving physical activity levels in youth with intellectual disabilities. These effects did not reach statistical significance for physical activity levels (d = 0.33; CI = -0.11 to 0.78; p = 0.14), number of steps per unit of time (d = 0.23; CI = -0.23 to 0.68; p = 0.32), and time spent inactive (d = 0.15; CI = -0.29 to 0.60; p = 0.50). @*Conclusion@#Home or community-based interventions may be effective in increasing physical activity levels in youth with intellectual disabilities. Further research with homogeneous outcome measures and larger sample sizes need to be conducted to build on the results of this review.

Pacientes oncológicos: um olhar sobre as dificuldades vivenciadas pelos familiares cuidadores / Pacientes oncológicos: una mirada sobre las dificultades vivenciadas por los familiares cuidadores / Oncology patients: a glance about the difficulties lived by the caretaking relatives

Os pacientes oncológicos freqüentemente precisam de ajuda contínua em sua vida diária. Geralmente um dos familiares se encarrega dessas atividades, dedicando-se por um longo período a esses cuidados. O objetivo da pesquisa consiste em fazer um levantamento das dificuldades vivenciadas pelos familiares cuidadores de pacientes oncológicos e verificar as técnicas de suporte apontadas pela literatura para eles. A coleta de dados foi realizada por meio da aplicação de uma entrevista estruturada na residência de 16 familiares cuidadores de pacientes oncológicos, no mínimo há 4 meses, não importando sexo, idade e grau de instrução. A análise seguiu uma proposta qualitativa e quantitativa. Dos resultados obtidos pode-se afirmar que os familiares cuidadores de pacientes oncológicos são pessoas propensas a adoecer com maior facilidade, o que pode lhes acarretar em sofrimento psíquico, bem como mobilizar seus conteúdos relacionados à morte. Esses cuidadores apresentam uma mudança abrupta em sua vida, bem como em sua rotina. Alguns deles relatam já perceber alguns sintomas psicossomáticos. Conclui-se que é extremamente importante a esses familiares procurem reservar um tempo para cuidar de si podendo assim dedicar-se melhor aos cuidados para com o paciente e desfrutar dos aspectos positivos dessa função.

The patients with cancer quite often need a continuous help in their everyday life. Usually, one of the relatives is put in charge of these activities, dedicating him/ herself for a long period to such cares. The purpose of this research is to make a survey of the difficulties experienced by the caretaking relatives of oncology patients and check the support techniques presented in literature to them. The data were collected through interviews with 16 relatives that take care of patients with cancer for at least 4 months, without considering sex, age or instruction level. The analysis followed a qualitative and quantitative proposal. From the results found, we can be sure that the relatives that take care of patients with cancer are people prone to get sick easily, what may cause a psychic suffering to them and thoughts about death. These caretakers present a sudden change in their life as well as in their daily routine. Some of them reported that they have already identified some psychosomatic symptoms. We concluded that it is extremely important that these relatives try to take some time to take care of themselves. Doing that, they will be able to dedicate themselves to their relatives with cancer in a more effective way and enjoy the positive aspects of their duty.

The feasibility of a porcine model of acute coronary occlusion and reperfusion using off-pump coronary artery bypass grafting

We developed an open-chest porcine model of acute coronary occlusion and surgical reperfusion, and attempted to prevent intra-operative ischaemic ventricular fibrillation (VF) by a Retrograde Intracoronary Glyceryl trinitrate (RIG) infusion into the occluded vessel. Five Yorkshire pigs (weight 50 +/- 1.1 kg), randomized into 3 groups, underwent median sternotomy under general anaesthesia. One pig (Group 1, control) underwent sternotomy and pericardiotomy only. Four pigs underwent acute left anterior descending (LAD) coronary occlusion. Two pigs were not reperfused (Group 2). Two pigs underwent surgical reperfusion (Group 3) via left internal mammary artery (LIMA) grafting to the LAD using the Off-Pump Coronary Artery Bypass (OPCAB) technique. Ischaemic injury was assessed using 7-lead electrocardiography (ECG) and transthoracic/epimyocardial echocardiography (ECHO). Group 1: transient intraoperative hypotension and VF occurred. Successful resuscitation and 10-week survival (until sacrifice) with normal left ventricular (LV) function was achieved. Group 2: there were ECG and ECHO evidence of acute LV ischaemic dysfunction in both pigs. The surviving pig had persistent anterior hypokinesis at 8 1/2 months. The other died intra-operatively following progressive ischaemic LV dysfunction despite resuscitative attempts. Group 3: the surviving pig had normal LV function at 8 months. Initial anterior LV akinesis normalized within 7 days. The other developed post-occlusion haemodynamic instability and died intra-operatively despite reperfusion. In this porcine model, acute LAD artery occlusion modified by the novel RIG infusion technique, followed by surgical reperfusion (OPCAB) is feasible. This model would facilitate further development of OPCAB surgical expertise and understanding of the pathophysiology of ischaemia-reperfusion injury.

HLA-B5 and B21 antigens in aortoarteritis.

The distribution of class I HLA antigens (HLA-A, B) were determined in 50 patients of Aortoarteritis in an Indian population. This included 29 females and 21 males. The difference in antigen frequency was observed between patients and controls with reference to HLA-A19, B5 and B21 antigens. A decreased frequency of HLA-A19 was observed in the patients as compared to controls (14% vs 33.25%, X2 = 6.81, P less than 0.025). Of the B locus antigens, an increased frequency of HLA B5 was observed in the patients as compared to controls (48% vs 29.5%, X2 = 6.2, P less than 0.025). HLA-B21 was also increased in the patients as compared to the controls (18% vs 6.5%, X2 = 6.67, P less than 0.025). These data suggest the involvement of genetic factor (s) in the aetiopathogenesis of this disease. Further, the observations indicate that HLA-B5 and B21 may be associated with Aortoarteritis.
