Day service programmes for people with a severe intellectual disability and quality of life: Parent and staff perspectives

This study focuses on the contributions of a community and campus based day programme to the quality of life of programme participants with a severe level of intellectual disability from the perspective of parents and staff. Qualitative interviews were carried out with parents and staff to explore the contribution that the two programmes had to participants' quality of life in the 6 months since the community based programme began. Schalock and Keith's Quality of Life Questionnaire was administered to supplement the qualitative data. Results indicated that the community based programme contributed more to participants' quality of life over the preceding 6 months than the campus based programme. This study revealed that community based participants' new-found social roles, their hobbies and their work opportunities had a positive effect on their quality of life.

[Multiple Ebola virus haemorrhagic fever outbreaks in Gabon, from October 2001 to April 2002]

Outbreaks of Ebola virus haemorrhagic fever have been reported from 1994 to 1996 in the province of Ogooué Ivindo, a forest zone situated in the Northeast of Gabon. Each time, the great primates had been identified as the initial source of human infection. End of November 2001 a new alert came from this province, rapidly confirmed as a EVHV outbreak. The response was given by the Ministry of Health with the help of an international team under the aegis of WHO. An active monitoring system was implemented in the three districts hit by the epidemic (Zadié, Ivindo and Mpassa) to organize the detection of cases and their follow-up. A case definition has been set up, the suspected cases were isolated at hospital, at home or in lazarets and serological tests were performed. These tests consisted of the detection of antigen or specific IgG and the RT-PCR. A classification of cases was made according to the results of biological tests, clinical and epidemiological data. The contact subjects were kept watch over for 21 days. 65 cases were recorded among which 53 deaths. The first human case, a hunter died on the 28th of October 2001. The epidemic spreads over through family transmission and nosocomial contamination. Four distinct primary foci have been identified together with an isolated case situated in the South East of Gabon, 580 km away from the epicenter. Deaths happened within a delay of 6 days. The last death has been recorded on the 22nd of March 2002 and the end of the outbreak was declared on the 6th of May 2002. The epidemic spreads over the Gabon just next. Unexplained deaths of animals had been mentionned in the nearby forests as soon as August 2001: great primates and cephalophus. Samples taken from their carcasses confirmed a concomitant animal epidemic.

Anticoagulation therapy in patients with chronic atrial fibrillation: a retrospective claims data analysis

OBJECTIVES

This study assessed the risk of thrombo embolic events and bleeding complications among atrial fibrillation patients.

METHODS

A cohort of patients with chronic non-valvular atrial fibrillation were identified from medical claims (diagnosis codes 427.31 and 427.32). Subjects were identified from 1 January 1998-31 December 2000 and were continuously enrolled for 6 months prior to the first occurring atrial fibrillation medical claim. Cox proportional hazards analysis with time varying covariates was used for the event analysis.

RESULTS

Of 6764 subjects retained for analysis, 3541 (52.4%) were exposed to warfarin. Adjusting for baseline characteristics, warfarin exposure was associated with lower likelihood of an arterial thromboembolic event compared to no exposure (HR: 0.710, CI: 0.540-0.934). No benefit was found in the use of warfarin in the prevention of intracranial events (HR: 1.119, CI: 0.929-1.349). Use of warfarin increased the risk of minor bleeding events (HR: 3.600, CI: 2.537-5.109), and all bleeding events (HR: 1.502, CI: 1.289-1.749).

CONCLUSIONS

The risk of arterial thromboembolic events was associated with warfarin exposure as expected. An increase in the risk of minor and total bleeding events among patients treated with warfarin was observed. The results of this study suggest that there may be a gap between the clinical trial and coagulation clinic performance of warfarin in reducing the risk of thromboembolic events versus what is achievable in general practice.

Augmentation of T-cell apoptosis by immunosuppressive agents

The regulatory benefit of apoptosis (activation-induced cell death, AICD) in T cells can be influenced by immunosuppressive agents. We examined this for mycophenolate mofetile (MMF, using it's active metabolite, mycophenolate (MPA)) compared with rapamycin (RAPA) and the calcineurin inhibitors (CI) cyclosporin (CYA) and FK506 (FK). Pure T cells from peripheral blood leucocytes (PBL) were stimulated by anti-CD3 plus anti-CD28. Cell division (sequential cohort reduction in carboxyflourescein diacetate succinimidyl ester, CFSE) was used to measure proliferation and determine status of different cell generations without or with added drug at 4 d. Apoptosis was measured by Annexin V staining of activated cells using flow cytometry. We confirmed in this stringent system the inhibition of AICD by CI and showed that RAPA is intermediate and MPA most effective in this potentiation of AICD.

The relation between pre-eclampsia at term and neonatal encephalopathy

OBJECTIVES

To determine whether pre-eclampsia, hypothesised to be an inflammatory condition, is associated with fever in term labour, and confirm and examine the reported association of pre-eclampsia at term with neonatal encephalopathy.

DESIGN

Prospective cohort study.

SETTING

A Dublin teaching hospital.

PARTICIPANTS

6163 women in labour with singleton pregnancies at term at low risk for intrapartum hypoxia, recruited to a randomised trial examining the effect of admission cardiotocography on neonatal outcome.

RESULTS

Pre-eclampsia was associated with maternal fever > 37.5 degrees in labour (odds ratio (OR) 3.39, 95% confidence interval (CI) 2.1 to 5.4); this was independent of obstetric intervention (adjusted OR 2.07, 95% CI 1.24 to 3.47). Pre-eclampsia was associated with neonatal encephalopathy (OR 25.5, 95% CI 8.4 to 74.7); this too was independent of obstetric intervention (adjusted OR 18.5, 95% CI 5.9 to 58.1). Cord arterial pH values were significantly lower in pre-eclamptics (7.20 v 7.24), although severe cord acidaemia was not significantly more common (OR 2.91, 95% CI 0.7 to 9.9). The association of pre-eclampsia with encephalopathy was independent of maternal fever (adjusted OR 16.5, 95% CI 5.1 to 54) and cord acidaemia (adjusted OR 13.5, 95% CI 3.2 to 56.7).

CONCLUSIONS

The association of pre-eclampsia with maternal fever at term supports the hypothesis that pre-eclampsia is an inflammatory condition. The association of pre-eclampsia with neonatal encephalopathy is independent of obstetric intervention and cannot be explained by either acidaemia or maternal fever. A systemic inflammatory response in the fetus, perhaps secondary to oxidative stress, could explain the link between maternal pre-eclampsia and neonatal encephalopathy, and this may occur through cerebral vasoconstriction.

Final inpatient rehabilitation PPS rule improves on proposed rule

On August 7, 2001, the Centers for Medicare and Medicaid Services (CMS--formerly HCFA) released the final rule for a new prospective payment system (PPS) for inpatient rehabilitation services describing the process that must be used to receive payment for such services provided to Medicare beneficiaries. The process consists of five steps: First, a clinician performs assessments of the patient upon admission and at discharge. Second, the patient is classified into a case-mix group (CMG) with an assigned relative-value weight within that CMG. Third, the Federal prospective payment rate is determined by multiplying the relative-value weight by an annually updated, budget-neutral conversion factor. Fourth, the Federal prospective payment rate is adjusted to account for facility-specific factors. Finally, the facility-adjusted payment rate may be adjusted for case-specific factors. The final rule eliminates three deficiencies in the proposed rule by providing increased payment for treating any comorbidities documented prior to the second day before discharge, providing more appropriate payment for transfer cases, and minimizing the paperwork associated with patient assessment.

Current status of liver tumors in children

Most tumors of the liver in children are malignant. Benign tumors occur most often in infants, are usually vascular, and seldom require surgery. Hepatoblastoma and hepatocellular carcinoma are the most common malignant tumors. Hepatoblastoma affects younger children and hepatocellular carcinoma affects older children and adolescents. Treatment consists of surgical resection before or after chemotherapy, and long-term survival is impossible without resection. Survival rate exceeds 80% in children with hepatoblastoma. Children with hepatocellular carcinoma and other more unusual malignant tumors do not do as well. Current treatment plans are described for both benign and malignant tumors of the liver.
