Abstract

The indication of bariatric surgery as therapeutic procedure for morbid obese patients requires the application of selection criteria which deal with the degree of obesity, associated complications and previous failure of conventional therapy. Alcohol or drug addiction and concomitant serious disease are contraindications for bariatric surgery. Before operation, a full assessment is needed to identify possible eating behaviour disturbances and associated comorbidity such as cardiovascular disease, sleep apnoea, metabolic and psychiatric alterations which might induce intra and postoperative complications. Surgical techniques can be classified as restrictive, malabsortive and mixed procedures. Gastroplasty and adjustable gastric banding are restrictive techniques, which are indicated in obese patients with body mass index less than 45 kg/m2. Mixed techniques are the most used procedures. They include gastric by-pass which causes a reduction of 60-70% of weight excess, biliopancreatic diversion and duodenal switch which can eliminate a 75% of body weight excess. Following bariatric surgery a dramatic improvement in associated comorbidity can be demonstrated, specially in what refers to diabetes, hypertension, dislipidaemia and apnoea. Postoperative mortality is around 1-2%. Peritonitis and venous thromboembolism are the most serious complications. Postoperative follow-up should be lifelong and requires a progressive nutrition planning and vitamin supplementation.

Brief family treatment intervention to promote aftercare among male substance abusing patients in inpatient detoxification: A quasi-experimental pilot study.

We developed a brief family treatment (BFT) intervention for substance abusing patients in inpatient detoxification to promote aftercare treatment post-detox. BFT consisted of meeting with the patient and a family member (spouse or parent) with whom the patient lived to review and recommend potential aftercare plans for the patient. A phone conference was used when logistics prevented an in-person family meeting. Results indicated that male substance abusing patients who received BFT (N=14), as compared with a matched treatment as usual (TAU) comparison group (N=14) that did not, showed a trend toward being more likely to enter an aftercare program and to attend more days of aftercare in the 3 months after detoxification. The magnitude of these differences favoring BFT over TAU was midway between a medium and a large effect size. Days using alcohol or drugs in the 3 months after detox were lower for treatment-exposed BFT patients who had an in-person family meeting than TAU counterparts (trend, medium effect), and for patients who entered aftercare regardless of treatment condition (significant large effect).

An evaluation of gender differences in the implementation and impact of a comprehensive approach to domestic violence.

The primary goal of society's response to domestic violence is the protection of the victim from further abuse. Recently, the coordinated community response (CCR) has been developed as one example of an approach aimed at reaching this goal. Prior research has generally found support for the model, with male offenders recidivating at lower rates. The current study examines whether a comprehensive, community-based approach is capable of reducing recidivism rates among male and female offenders. Comparisons are made between 70 female and 131 male offenders. Specific attention is given to the intervention process, including differences in service or treatment component completion and recidivism by gender.

Ideal timing to transfer from an acute care hospital to an interdisciplinary inpatient rehabilitation program following a stroke: an exploratory study.

BACKGROUND: Timely accessibility to organized inpatient stroke rehabilitation services may become compromised since the demand for rehabilitation services following stroke is rapidly growing with no promise of additional resources. This often leads to prolonged lengths of stays in acute care facilities for individuals surviving a stroke. It is believed that this delay spent in acute care facilities may inhibit the crucial motor recovery process taking place shortly after a stroke. It is important to document the ideal timing to initiate intensive inpatient stroke rehabilitation after the neurological event. Therefore, the objective of this study was to examine the specific influence of short, moderate and long onset-admission intervals (OAI) on rehabilitation outcomes across homogeneous subgroups of patients who were admitted to a standardized interdisciplinary inpatient stroke rehabilitation program. METHODS: A total of 418 patients discharged from the inpatient neurological rehabilitation program at the Montreal Rehabilitation Hospital Network after a first stroke (79% of all cases reviewed) were included in this retrospective study. After conducting a matching procedure across these patients based on the degree of disability, gender, and age, a total of 40 homogeneous triads (n = 120) were formed according to the three OAI subgroups: short (less than 20 days), moderate (between 20 and 40 days) or long (over 40 days; maximum of 70 days) OAI subgroups. The rehabilitation outcomes (admission and discharge Functional Independence Measure scores (FIM), absolute and relative FIM gain scores, rehabilitation length of stay, efficiency scores) were evaluated to test for differences between the three OAI subgroups. RESULTS: Analysis revealed that the three OAI subgroups were comparable for all rehabilitation outcomes studied. No statistical difference was found for admission (P = 0.305-0.972) and discharge (P = 0.083-0.367) FIM scores, absolute (P = 0.533-0.647) and relative (P = 0.496-0.812) FIM gain scores, rehabilitation length of stay (P = 0.096), and efficiency scores (P = 0.103-0.674). CONCLUSION: OAI does not seem to affect significantly inpatient stroke rehabilitation outcomes of patients referred from acute care facilities where rehabilitation services are rapidly initiated after the onset of the stroke and offered throughout their stay. However, other studies considering factors such as the type and intensity of the rehabilitation are required to support those results.
