A Review of Interventions to Reduce Mechanical Restraint and Seclusion among Adult Psychiatric Inpatients
Objective: This review examines nature and effectiveness of interventions to reduce the use of mechanical restraint and seclusion among adult psychiatric inpatients.
Method: Electronic searches were conducted to locate post-1960 empirical studies of restraint and seclusion reduction in English. A total of 36 studies were identified, mostly from the USA. Analysis was conducted using a structured data extraction tool.
Results: The majority of studies reported reduced levels or mechanical restraint and/or seclusion, but the standard of evidence was poor. There were no randomised trials. Most were retrospective studies of official records before and after the intervention was introduced, with varying follow-up periods. The interventions were diverse, but tended to include one or more of the following: new restraint and/or seclusion policies, staffing changes, staff training, review procedures and crisis management initiatives. The research was unable to address which of these elements was most effective. There was also evidence that some improved outcomes were achieved by substituting restraint or seclusion for each other or for alternatives forms of containment (medication in particular). Nurses’ attitudes, skills and approach to patient care were absent from the literature.
Conclusions: Interventions probably can reduce the use of restraint and seclusion, but better designed research is required to demonstrate their effectiveness conclusively. More attention should also be paid to understanding how interventions work, particularly from the perspective of nursing staff. This is essential to the successful implementation of restraint and seclusion interventions across different psychiatric settings and treatment populations
Self-rated health among Mayan women participating in a randomised intervention trial reducing indoor air pollution in Guatemala
<p>Abstract</p> <p>Background</p> <p>Indoor air pollution (IAP) from solid fuels is a serious health problem in low-income countries that can be alleviated using improved stoves. Although women are the principal users, few studies have investigated the self-assessed impact of the stoves on their health and lives.</p> <p>Methods</p> <p>This study was conducted in rural highland Guatemala, involving 89 intervention and 80 control Mayan Indian young women (mean 27.8 years, SD 7.2). Outcomes were assessed after approximately 18 months use of the new stove. Our objectives were to compare self-rated health and change in health among women participating in a randomised control trial comparing a chimney stove with an open fire, to describe impacts on women's daily lives and their perceptions of how reduced kitchen smoke affects their own and their children's health.</p> <p>Results</p> <p>On intention-to-treat analysis, 52.8% of intervention women reported improvement in health, compared to 23.8% of control women (p < 0.001). Among 84 intervention women who reported reduced kitchen smoke as an important change, 88% linked this to improvement in their own health, particularly for non-respiratory symptoms (for example eye discomfort, headache); 57% linked reduced smoke to improvement in their children's health, particularly sore eyes.</p> <p>Conclusion</p> <p>Women's perception of their health was improved, but although smoke reduction was valued, this was linked mainly with alleviation of non-respiratory symptoms like eye discomfort and headache. More focus on such symptoms may help in promoting demand for improved stoves and cleaner fuels, but education about more severe consequences of IAP exposure is also required.</p
Carnosine:can understanding its actions on energy metabolism and protein homeostasis inform its therapeutic potential?
The dipeptide carnosine (β-alanyl-L-histidine) has contrasting but beneficial effects on cellular activity. It delays cellular senescence and rejuvenates cultured senescent mammalian cells. However, it also inhibits the growth of cultured tumour cells. Based on studies in several organisms, we speculate that carnosine exerts these apparently opposing actions by affecting energy metabolism and/or protein homeostasis (proteostasis). Specific effects on energy metabolism include the dipeptide's influence on cellular ATP concentrations. Carnosine's ability to reduce the formation of altered proteins (typically adducts of methylglyoxal) and enhance proteolysis of aberrant polypeptides is indicative of its influence on proteostasis. Furthermore these dual actions might provide a rationale for the use of carnosine in the treatment or prevention of diverse age-related conditions where energy metabolism or proteostasis are compromised. These include cancer, Alzheimer's disease, Parkinson's disease and the complications of type-2 diabetes (nephropathy, cataracts, stroke and pain), which might all benefit from knowledge of carnosine's mode of action on human cells. © 2013 Hipkiss et al.; licensee Chemistry Central Ltd
The Effectiveness of Contract Farming for Raising Income of Smallholder Farmers in Low- and Middle-Income Countries: a Systematic Review
Contract farming is used by an increasing number of firms as a preferred modality to source products from smallholder farmers in low and middle-income countries. Quality requirements of consumers, economies of scale in production or land ownership rights are common incentives for firms to offer contractual arrangements to farmers. Prices and access to key technology, key inputs or support services are the main incentives for farmers to enter into these contracts. There is great heterogeneity in contract farming, with differences in contracts, farmers, products, buyers, and institutional environments. The last decade shows a rapid increase in studies that use quasi-experimental research designs to assess the effects of specific empirical instances of contract farming on smallholders. The objective of this systematic review was to distill generalised inferences from this rapidly growing body of evidence. The review synthesised the studies in order to answer two questions: 1: What is known about the effect size of contract farming on income and food security of smallholder farmers in low- and middle-income countries? 2: Under which enabling or limiting conditions are contract farming arrangements effective for improving income and food security of smallholders
Treatment of bipolar disorder: a complex treatment for a multi-faceted disorder
Background: Manic-depression or bipolar disorder (BD) is a multi-faceted illness with an inevitably complex treatment. Methods: This article summarizes the current status of our knowledge and practice of its treatment. Results: It is widely accepted that lithium is moderately useful during all phases of bipolar illness and it might possess a specific effectiveness on suicidal prevention. Both first and second generation antipsychotics are widely used and the FDA has approved olanzapine, risperidone, quetiapine, ziprasidone and aripiprazole for the treatment of acute mania. These could also be useful in the treatment of bipolar depression, but only limited data exists so far to support the use of quetiapine monotherapy or the olanzapine-fluoxetine combination. Some, but not all, anticonvulsants possess a broad spectrum of effectiveness, including mixed dysphoric and rapid-cycling forms. Lamotrigine may be effective in the treatment of depression but not mania. Antidepressant use is controversial. Guidelines suggest their cautious use in combination with an antimanic agent, because they are supposed to induce switching to mania or hypomania, mixed episodes and rapid cycling. Conclusion: The first-line psychosocial intervention in BD is psychoeducation, followed by cognitive-behavioral therapy. Other treatment options include Electroconvulsive therapy and transcranial magnetic stimulation. There is a gap between the evidence base, which comes mostly from monotherapy trials, and clinical practice, where complex treatment regimens are the rule
Weight gain and metabolic issues of medicines used for bipolar disorder
Patients with bipolar disorder are at high risk of gaining weight and developing metabolic illnesses, and pharmacologic treatment for the disorder may significantly increase this risk. This paper reviews the literature on the metabolic consequences of the medications used in bipolar disorder and describes the possible strategies to prevent, monitor, and treat the common metabolic illnesses that patients with bipolar disorder may develop during treatment.

Relevance of elevated microparticles in peripheral blood and synovial fluid of patients with rheumatoid arthritis
Introduction: Microparticles (MPs) are submicron sized heterogeneous membrane-bound vesicles released from cells undergoing cell activation or apoptosis. Elevated platelet-derived MPs (PMPs) are reported in rheumatic diseases. We profiled Annexin-V+ MPs and CD61+ MPs in plasma and synovial fluid of patients with rheumatoid arthritis (RA) and their clinical correlates.
Methods: Twenty-three newly diagnosed disease-modifying anti-rheumatic drug naïve patients with RA, 17 with osteoarthritis (OA) and 22 healthy controls (HC) were enrolled. Five milliliters of synovial fluid from the knee joint of patients with RA and OA was collected; 5 ml of peripheral blood was collected from patients with RA, OA, and HC. Cell-free synovial fluid and platelet poor plasma samples were stained with Annexin-V-APC and Anti-CD61-BV510 antibodies followed by flow cytometry analysis (FACSAria III) (results expressed as the mean ± standard deviation of % population).
Results: Significantly greater levels of synovial fluid MPs (Annexin-V+ MPs) were observed in RA versus OA (P < 0.0001), significantly higher synovial fluid PMPs (Annexin V+ CD61+ MPs) levels in RA compared to HC (P = 0.0472). MPs other than those of platelet origin (Annexin V+ CD61− MPs) were also increased in the synovial fluid of RA patients compared to OA (P < 0.0001). Kruskal–Wallis test revealed the significant difference in the levels of plasma MPs (Annexin-V+), PMPs (Annexin V+ CD61+ MPs), and MPs other than those of platelet origin (Annexin V+ CD61− MPs) between RA, OA, and HC groups (P < 0.0001) with a higher percentage in RA group.
Conclusions: Higher levels of Annexin-V+ MPs in both plasma and synovial fluid of RA suggest a role for MPs in the pathogenesis of RA. Elevated plasma PMPs (Annexin V+ CD61+ MPs) in RA may suggest their role in systemic involvement. Furthermore, increased levels of MPs other than those of platelet origin (Annexin V+ CD61− MPs) indicate the necessity to study the MPs from other cell lineages
