Effects of cardiac rehabilitation after coronary artery bypass grafting on readmissions, return to work, and physical fitness. A case-control study

In a case-control study 49 consecutive post-coronary artery bypass grafting (CABG) patients (10 f, 39 m) participating in a comprehensive rehabilitation programme were compared with 98 individually matched double control patients, receiving standard care. The rehabilitation programme, starting 6 weeks after surgery, consisted of follow-up at a coronary clinic, repeated health education, and physical training in out-patient groups. During the first year after CABG, fewer study group patients were readmitted to hospital (14% vs 32%, p less than 0.01) and on fewer occasions (1.1 vs 2.9, p less than 0.05). Fewer patients used anxiolytic drugs (0% vs 15%, p less than 0.01). At the one year post-CABG exercise test we found in the study group a tendency to a greater increase in work capacity, as compared with the values obtained at the preoperative exercise test (33 vs 25 W ns). There were no differences in the rates of returning to work (59% vs 64%). In a long-term follow-up study (av. 38 months post-CABG) the patients were asked to fill in a questionnaire evaluating perceived physical work capacity and training habits. The study group patients rated their physical work capacity higher, and more patients had continued with regular physical training (66% vs 46%, p = 0.05). There were fewer patients using anxiolytic drugs (9% vs 30%, p less than 0.01). Although the programme did not influence the return to work we conclude that it improved the quality of life of our patients as it entailed fewer readmissions and reduced the use of anxiolytic medication; in addition it promoted physical fitness and training habits.     

Hamster endogenous retrovirus (HaER) isolated from SV-40 induced tumor cells

A hamster cell line obtained from a secondary transplanted SV-40-induced tumor was found to spontaneously release type C virus particles. The particles possessed all biochemical features characteristic of retroviruses and induced syncytium formation in XC cells but were not oncogenic for hamsters. Nucleic acid hybridization assays demonstrated that the isolated virus was an endogenous retrovirus of hamster, lacking sequence homology with mouse and other animal species.     

Genesis,ultrastructure and cytochemical study of the cat eosinophil

Eosinophils from cat bone marrow and peripheral blood were studied by electron microscopy and cytochemical procedures. The maturation of eosinophils and formation of typical granules were described. Contrary to the accepted opinion that the core of animal's eosinophilic specific granules have a crystal-like structure, our observations revealed that the core has a myelin-like cylindrical appearance, whose layered formation proceeds from the inside outwards. Electron microscopic observations revealed that localization of reaction product to potassium pyroantimonate and phosphotungstic acid and to acid phosphatase activity was similar to that of eosinophils of man and other animals. Antimonate deposits and acid phosphatase activity were detected between the layers of the myelin-like structure of the core. Eosinophil granules failed to yield a positive reaction for peroxidase activity. The secretory activity of the eosinophil is discussed.     

Guidance of Post Myocardial Infarction Ventricular Septal Defect and Pseudoaneurysm Closure

Left ventricular pseudoaneurysm and ventricular septal defect are rare but devastating complications of myocardial infarction. With medical treatment alone, the majority of patients will die from these complications. Until recently, the recommended treatment was surgical closure. These surgeries carried extreme risk due to abnormal hemodynamics, necrotic substrates and the comorbidities of these patients. Recently, trans-catheter closure was shown to be an acceptable alternative to open surgical intervention. 3D echocardiography identifies the location, size, and shape of the defect and can assess, guide, and follow up the closure procedure.     

Asistencia al niño y adolescente con diabetes. Unidades de referencia en diabetes pediátrica

Intensive treatment of type 1 diabetes mellitus (DM1) delays and slows down the progression of chronic diabetes complications (DCCT 1993).This type of treatment in children and adolescents with DM1 has a different complexity to other stages of life and therefore, needs specialized care units. Various documents and declarations of diabetic patient's rights are evaluated, and the need for an adequate health care is emphasized.In the last decade, several projects have been developed in Europe to create a benchmark treatment of pediatric diabetes, with the aim of establishing hospitals with highly qualified healthcare to control it.The Diabetes Working Group of the Spanish Society for Pediatric Endocrinology (SEEP) has prepared this document in order to obtain a national consensus for the care of children and adolescents with type 1 diabetes in specialist Pediatric Diabetes Units, and at the same time advise Health Care Administrators to establish a national healthcare network for children and adolescents with diabetes mellitus, and organize comprehensive pediatric diabetes care units in hospitals with a reference level in quality of care.     

Exposure to Family Violence of Israeli Inmates: Does Sex Make a Difference?

The purpose of the current study was to examine differences by sex (a) in history of child abuse and neglect (CAN) and exposure to parental partner violence (PPV); and (b) in the association of CAN and PPV with violent offenses, substance use, suicidal behavior, and psychiatric problems. This cross-sectional study investigated sex differences in CAN and exposure to PPV in a sample of 290 Israeli inmates (65 women and 225 men). Participants completed a self-report measures of the Childhood Trauma Questionnaire, and the revised Conflict Tactics Scale to measure PPV. The findings indicated that the female inmates had experienced significantly more sexual abuse (p?<?.001), and more exposure to PPV (p?=?.030), compared with male inmates. Female inmates who had experienced CAN were at higher risk of committing violent offenses than male inmates and female inmates were also more likely than male inmates to have been engaged in suicidal behaviors (39.3% and 18.5%, respectively), and to have had psychiatric problems (40% and 14.2%, respectively). The findings also revealed that psychiatric problems and suicidal behavior can be predicted by CAN and family substance use. The findings highlight the effects of the adverse childhood experience of exposure to CAN and PPV on behavioral problems. Appropriate treatment requires simultaneous intervention that targets all three issues of childhood trauma, substance use disorders, and psychiatric problems for both sexes.
