Adverse event reporting in studies of penetrating acupuncture during pregnancy: a systematic review

Background - Acupuncture within pregnancy has frequently been investigated, often with finding this to be more effective than standard care. However, the adverse event severity, types and occurrence are unclear. Objective - To investigate the quality of reporting adverse events and to attempt to identify occurrence, type and severity of adverse events in acupuncture and non-acupuncture groups. Results - Overall quality of reporting of adverse events was poor, with information describing the adverse events often lacking in detail. A number of trends were noted: adverse events occurring within a treatment session was 3%-17% in the acupuncture groups and 4-25% in the non-acupuncture groups. The percentage of women affected by an adverse event was between 14%-17% in the acupuncture groups and 15-19% in non-acupuncture groups. Conclusions - Adverse event reporting within acupuncture trials is generally poor. The trends noted were that adverse events do occur, but would appear to be largely minor and comparable to non-acupuncture related interventions

Altered H19/miR‐675 expression in skeletal muscle is associated with low muscle mass in community‐dwelling older adults

Background: Despite increasing knowledge of the pathogenesis of muscle ageing, the molecular mechanisms are poorly understood. Based on an expression analysis of muscle biopsies from older Caucasian men, we undertook an in-depth analysis of the expression of the long non-coding RNA, H19, to identify molecular mechanisms that may contribute to the loss of muscle mass with age. Methods: We carried out transcriptome analysis of vastus lateralis muscle biopsies from 40 healthy Caucasian men aged 68–76 years from the Hertfordshire Sarcopenia Study (HSS) with respect to appendicular lean mass adjusted for height (ALMi). Validation and replication was carried out using qRT-PCR in 130 independent male and female participants aged 73–83 years recruited into an extension of the HSS (HSSe). DNA methylation was assessed using pyrosequencing. Results: Lower ALMi was associated with higher muscle H19 expression (r2 = 0.177, P < 0.001). The microRNAs, miR-675-5p/3p encoded by exon 1 of H19, were positively correlated with H19 expression (Pearson r = 0.192 and 0.182, respectively, P < 0.03), and miR-675-5p expression negatively associated with ALMi (r2 = 0.629, P = 0.005). The methylation of CpGs within the H19 imprinting control region (ICR) were negatively correlated with H19 expression (Pearson r = −0.211 to −0.245, P ≤ 0.05). Moreover, RNA and protein levels of SMAD1 and 5, targets of miR-675-3p, were negatively associated with miR-675-3p (r2 = 0.792 and 0.760, respectively) and miR-675-5p (r2 = 0.584 and 0.723, respectively) expression, and SMAD1 and 5 RNA levels positively associated with greater type II fibre size (r2 = 0.184 and 0.246, respectively, P < 0.05). Conclusions: Increased expression profiles of H19/miR-675-5p/3p and lower expression of the anabolic SMAD1/5 effectors of bone morphogenetic protein (BMP) signalling are associated with low muscle mass in older individuals

Critical time Intervention for Severely mentally ill Prisoners (CrISP): a randomised controlled trial

Background The transition from prison to community is difficult for prisoners with mental illness. Critical time intervention (CTI) is designed to provide intensive support to meet health, social care and resettlement needs through close working between client and key worker pre, and up to 6 weeks post, release. Objectives To establish whether or not CTI is effective in (1) improving engagement of discharged male prisoners who have mental illness with community mental health teams (CMHTs) and (2) providing practical support with housing, finance and re-establishing social networks. Trial design A multicentre, parallel-group randomised controlled trial, with follow-up at 6 weeks and at 6 and 12 months. A subset of prisoners and case managers participated in a complementary qualitative study. Setting Eight English prisons. Participants One hundred and fifty adult male prisoners, convicted or remanded, cared for by mental health in-reach teams and diagnosed with severe mental illness, with a discharge date within 6 months of the point of recruitment. Intervention Participants were randomised to either the intervention or the control (treatment as usual). The intervention group was assigned a case manager who assessed mental and physical health before and following release, made appropriate links to health, housing and financial services and supported the re-establishment of family/peer contact. Outcome The primary outcome measure was engagement with a CMHT 6 weeks post discharge. Secondary outcomes included contact with mental health services at 6 and 12 months. A health economic evaluation was undertaken using service contact at the follow-up time points. We were unable to assess the intervention’s effect on reoffending and longer-term health-care use because of study delays. Results One hundred and fifty prisoners were recruited: 72 were randomised to the intervention and 78 were randomised to the control. Engagement with teams at 6 weeks was 53% for the intervention group compared with 27% for the control group [95% confidence interval (CI) 0.13% to 0.78%; p = 0.012]. At 6 months’ follow-up, intervention participants showed continued increase in engagement with teams compared with control participants (95% CI 0.12% to 0.89%; p = 0.029); there were no significant differences at 12 months. Increased engagement resulted in higher levels of service use and costs for the intervention than for the control. Qualitative data showed the intervention group reporting better continuity of care and improved access to services. Conclusion The intervention significantly improved contact with services at 6 weeks, although at a higher cost than the control. This is important as, in the days and weeks following release, recently released individuals are at a particularly high risk of suicide and drug overdose. Further research is required to establish how teams can better maintain contact with clients when the intervention ends. Future work Further studies are indicated for groups with different needs, for example women, young prisoners and those in police custody, and at other transition points, for example following arrest and short-term custody, and at points of transition between different mental health services.

Cytogenetic analysis of an exposed-referent study: perchloroethylene-exposed dry cleaners compared to unexposed laundry workers

<p>Abstract</p> <p>Background</p> <p>Significant numbers of people are exposed to tetrachloroethylene (perchloroethylene, PCE) every year, including workers in the dry cleaning industry. Adverse health effects have been associated with PCE exposure. However, investigations of possible cumulative cytogenetic damage resulting from PCE exposure are lacking.</p> <p>Methods</p> <p>Eighteen dry cleaning workers and 18 laundry workers (unexposed controls) provided a peripheral blood sample for cytogenetic analysis by whole chromosome painting. Pre-shift exhaled air on these same participants was collected and analyzed for PCE levels. The laundry workers were matched to the dry cleaners on race, age, and smoking status. The relationships between levels of cytological damage and exposures (including PCE levels in the shop and in workers' blood, packyears, cumulative alcohol consumption, and age) were compared with correlation coefficients and t-tests. Multiple linear regressions considered blood PCE, packyears, alcohol, and age.</p> <p>Results</p> <p>There were no significant differences between the PCE-exposed dry cleaners and the laundry workers for chromosome translocation frequencies, but PCE levels were significantly correlated with percentage of cells with acentric fragments (R²= 0.488, p < 0.026).</p> <p>Conclusions</p> <p>There does not appear to be a strong effect in these dry cleaning workers of PCE exposure on persistent chromosome damage as measured by translocations. However, the correlation between frequencies of acentric fragments and PCE exposure level suggests that recent exposures to PCE may induce transient genetic damage. More heavily exposed participants and a larger sample size will be needed to determine whether PCE exposure induces significant levels of persistent chromosome damage.</p

Nutritional supplementation for type 2 diabetes: a systematic review

The role of nutritional supplementation is of increasing interest with regard to ocular disease. Randomised controlled trials have demonstrated the effectiveness of supplementation for age-related macular degeneration, and formulations are now being developed for use by people with diabetes and diabetic retinopathy. The aim of this review was to synthesise the evidence for use of nutritional supplementation in type 2 diabetes. MEDLINE and EMBASE databases were searched using a systematic approach. Only double-masked randomised controlled trials were selected. A total of 50 trials were identified as suitable for inclusion. The potential role of alpha-lipoic acid, chromium, folic acid, isoflavones, magnesium, Pycnogenol®, selenium, vitamin C, vitamin E, and zinc in the treatment of type 2 diabetes is discussed. The review of trials identifies positive effects of these nutrients on various outcome measures relating to insulin resistance and cardiovascular factors. Chromium was the most studied supplement, accounting for 16 of the 50 trials. A majority of the trials found a positive effect of chromium on fasting plasma glucose. Isoflavones were found to have a positive effect on insulin resistance and cardiovascular outcome measures, but only when combined with soy proteins. Vitamin E is reported to reduce oxidative stress at levels of 200 mg day-1 or more

The effectiveness of neighborhood watch

Background: Neighborhood watch (also known as block watch, apartment watch, home watch and community watch) grew out of a movement in the US during the late 1960s that promoted greater involvement of citizens in the prevention of crime. Since then, interest in neighborhood watch has grown considerably and recent estimates suggest that over a quarter of the UK population and over forty per cent of the US population live in areas covered by neighborhood watch schemes. Objectives: The primary aim of this review is to assess the effectiveness of neighborhood watch in reducing crime
