Health care worker opinions on use of isolation precautions in long-term care facilities

To address controversies surrounding contact isolation precautions in skilled nursing facilities (SNF), we surveyed 356 nurses and nurses' aides from 7 SNFs on their opinions regarding benefits and harms of contact isolation precautions. Whereas a majority of health care workers believed that contact isolation reduces transmission of antibiotic-resistant organisms, they were also concerned about potentially harmful consequences to the SNF residents including depression and isolation.     

Effectiveness and tolerability of schizophrenia treatment in Central and Eastern Europe: results after 1 year from a prospective,observational study (IC-SOHO)

Objective. The Intercontinental Schizophrenia Outpatient Health Outcomes (IC-SOHO) study is intended to complement smaller, shorter-term observational studies and randomised controlled clinical trials in providing information on the treatment of schizophrenia in various geographies that have not been well studied previously.

Methods. Interim results after 12 months are presented for a subset of patients from eight Central and Eastern European (CEE) countries initiating or switching to olanzapine, risperidone, or typical antipsychotic monotherapy at Baseline (n=1387).

Results. Patients initially prescribed olanzapine and risperidone experienced significantly greater improvements in a broad range of schizophrenia symptom domains compared with patients prescribed typicals. Furthermore, patients in the olanzapine group showed significantly greater improvements in overall and negative symptom domains compared with the risperidone group (all P≤0.05). While patients in the olanzapine group gained more weight than the other two groups, they had significantly lower odds of developing extrapyramidal symptoms, loss of libido, and sexual dysfunction. Patients initially prescribed olanzapine were also significantly less likely to have changed or added antipsychotics during 12 months of treatment compared with the risperidone and typicals groups.

Conclusion. In this CEE sample, schizophrenia treatment outcomes after 12 months varied between patients initially prescribed different antipsychotics.     

Characterisation of cannabinoid 1 receptor expression in the perikarya, and peripheral and spinal processes of primary sensory neurons

The cannabinoid 1 (CB1) receptor is expressed by a sub-population of primary sensory neurons. However, data on the neurochemical identity of the CB1 receptor-expressing cells, and CB1 receptor expression by the peripheral and central terminals of these neurons are inconsistent and limited. We characterised CB1 receptor expression in dorsal root ganglia (DRG) and spinal cord at the lumbar 4–5 level, as well as in the urinary bladder and glabrous skin of the hindpaw. About 1/3 of DRG neurons exhibited immunopositivity for the CB1 receptor, the majority of which showed positivity for the nociceptive markers calcitonin gene-related peptide (CGRP) or/and Griffonia (bandeiraea) simplicifolia IB4 isolectin-binding. Virtually all CB1 receptor-immunostained fibres showed immunopositivity for CGRP in the skin, while very few did in the urinary bladder. No CB1 receptor-immunopositive nerve fibres were IB4 positive in either peripheral tissue. Spinal laminae I and II-outer showed the highest density of CB1 receptor-immunopositive punctae, the majority of which showed positivity for CGRP or/and IB4 binding. These data indicate that a major sub-population of nociceptive primary sensory neurons expresses CB1 receptors that are transported to both peripheral and central terminals of these cells. Therefore, the present data suggest that manipulation of endogenous CB1 receptor agonist levels in these areas may significantly reduce nociceptive input into the spinal cord.     

Ventriculosubgaleal shunt in the treatment of posthemorrhagic and postinfectious hydrocephalus of premature infants

Purpose

The aim of the study was to compare the characteristics of ventriculosubgaleal shunts during the clinical course of posthemorrhagic and postinfectious hydrocephalus in the neonatal period.

Patients and methods

The study comprised 102 premature babies in whom subgaleal shunt was consecutively inserted between 2006 and 2011. Seventy-two patients had posthemorrhagic hydrocephalus (mean gestational age 27.3?±?2.1 weeks, mean birth weight 1,036.9?±?327.7 g, mean age at insertion 51.4?±?56.2 days) and 30 patients were operated postinfectiously (27.5?±?2.2 weeks, 1,064.7 g?±?310.7 g, 115.9?±?47.8 days).

Results

The mean survival of subgaleal shunts was 87.9 days for the posthemorrhagic group and 75.6 days for the postinfectious group. Only six infants (8.3 %) did not need ventriculoperitoneal shunts later, all posthemorrhagic. There were meaningful differences between two groups with regard to ventriculosubgaleal shunt-related infections (8.3 % in posthemorrhagic versus 20.0 % in postinfectious) and shunt revision rate (6.9 % in posthemorrhagic versus 13.3 % in postinfectious), but these were not statistically significant. The need of ventriculoscopic procedures was notably more frequent in postinfectious group (1.4 versus 23.3 %).

Conclusion

In premature infants with ventriculomegaly, the subgaleal shunt is an effective temporary diversion tool. The complications were less with posthemorrhagic than with postinfectious hydrocephalus. With previous severe infections of prematures, the risk for complications regarding infection and obstruction will be 2.75 and 2.06 (odds ratios) times higher and more frequent need of ventriculoscopic procedures should be considered (odds ratio 21.6).     

Association between serum resistin level and outcomes in kidney transplant recipients

Resistin is an adipocytokine that is associated with inflammation, coronary artery disease, and other types of cardiovascular disease among patients with normal kidney function. However, little is known about the association of resistin with outcomes in kidney transplant recipients. We collected socio‐demographic and clinical parameters, medical and transplant history, and laboratory data from 988 prevalent kidney transplant recipients enrolled in the Malnutrition‐Inflammation in Transplant—Hungary Study (MINIT‐HU study). Serum resistin levels were measured at baseline. Associations between serum resistin level and death with a functioning graft over a 6‐year follow‐up period were examined in unadjusted and adjusted models. The mean±SD age of the study population was 51 ± 13 years, among whom 57% were men and 21% were diabetics. Median serum resistin concentrations were significantly higher in patients who died with a functioning graft as compared to those who did not die during the follow‐up period (median [IQR]: 22[15–26] vs. 19[14–22] ng/ml, respectively; P < 0.001). Higher serum resistin level was associated with higher mortality risk in both unadjusted and fully adjusted models: HRs (95% CI): 1.33(1.16–1.54) and 1.21(1.01–1.46), respectively. In prevalent kidney transplant recipients, serum resistin was an independent predictor of death with a functioning graft.
