Background Recently, the effects of erector spinae plane block on postoperative pain have become increasingly controversial. This meta-analysis compared the effects of ESP block versus placebo on postoperative analgesia and side effects to determine whether the new technique is a reliable alternative for pain management. Methods PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), and Wanfang Database were searched for clinical studies investigating the analgesic effect of ESP block versus placebo. The primary outcomes included the visual analogue scale (VAS) at rest and during movement, as well as the postoperative morphine consumption in 24 h, and the secondary outcome was the rate of postoperative nausea and vomiting (PONV). The choice of using the fixed or random-effects model depended on whether the heterogeneity tested by I2 statistic was more than 50%. Seeking sources of heterogeneity and exploring the effect of clinical details on the final result were performed by subgroup analysis. Additionally, the test for stability of the pooled result was realized by sensitivity analysis. Finally, we evaluated the quality of the evidence for the outcomes. STATA 13.0 software was selected as the main analysis software in the meta-analysis. Results Eighteen randomized controlled trials (RCTs) comprising 1041 patients were reviewed. This meta-analysis showed that ESP block could significantly reduce patients’ pain scores at 1 h, 6 h, 12 h, and 24 h after surgery at rest or during movement; 24-h postoperative morphine consumption; and the incidence of PONV. Conclusions ESP block as a novel technique exhibited superior postoperative analgesic effects, reducing the postoperative complications in spinal, thoracic, and abdominal surgeries during the early postoperative period. However, as a new nerve block technique, numerous large-sized RCTs are needed for further research.Fruit and vegetable consumption is low compared to recommendations worldwide. Few studies have investigated intakes of fruit and vegetables and barriers to meeting recommendations in a mixed-method design. Moreover, there is a need to better understand differences in these barriers by population subgroups. This study aimed to examine fruit and vegetable intake and barriers to meeting recommendations and differences by sex, age and socio-economic groups. selleck products Data on adults from the cross-sectional Greater Bendigo Active Living Census 2014 were used. Participants self-reported intake of fruit and vegetables and completed an open-ended question on barriers to meeting recommended intakes. Logistic regression analyses were used to examine odds of meeting recommended intakes. Leximancer was used for thematic analyses of barriers. A total of 13,788 individuals (54% female, 52.1 (SD 17.7) years) were included in the quantitative analyses. Qualitative data were available for 5649 of these individuals. Only seven percent of participants met recommended intakes for fruit and vegetables. Barriers were lack of time, that guidelines were perceived as unachievable, the wide variety of other foods available and the high cost and limited availability of fresh fruit and vegetables. The most relevant barriers by subgroups were taste (12%) and lack of appetite (18%) for males and females, respectively; lack of time (26-28%) and lack of appetite (70%) for young to middle aged adults and older adults, respectively and cost (35%) and availability of fresh fruits and vegetables (22%) for rural and disadvantaged groups. Findings have implications for the design of healthy eating strategies, which may benefit from being tailored to key population groups.The world is facing a medical crisis amid the CoViD-19 pandemic and the role of adequate hygiene and hand sanitisers is inevitable in controlling the spread of infection in public places and healthcare institutions. There has been a great surge in demand for hand sanitisation products leading to shortages in their supply. A consequent increase of substandard products in the market has raised safety concerns. This article, therefore, presents a critical review of hand sanitation approaches and products available on the market in light of the scientific evidence available to date. This review also provides a range of hand sanitisation product formulations, and manufacturing instructions to allow for extemporaneous preparations at the community and hospital pharmacies during this urgent crisis. In addition, this emergent situation is expected to continue, hence hand sanitisers will be in demand for an extended time, and the availability and purchase of substandard products on the market create an ongoing safety concern. Therefore, this article shall also provide various commercial organisations, interested in stepping forward the production and marketing of hand sanitisers, with a guide on the development of products of standardised ingredients and formulations.The DNA fragmentation and failure in post-meiotic maturation of the spermatozoa because of testosterone withdrawal can affect the fertilization potential in varicocele (VCL) patients. To find out the exact mechanism of VCL-induced failure in histone-protamine replacement process and DNA fragmentation, the correlations between the levels of expression of HSP70-2a, HSP90, PCNA, TP1/2 and PCNA genes and the patterns of DNA methylation were investigated before and after testosterone administration in rats. In total, 40 mature male Wistar rats (10 in each group) were assigned between control (with no intervention), control-sham (undergone a simple laparotomy), VCL-induced (VCL-sole), and testosterone-treated VCL-induced (VCLT) groups. The HSP70-2a, HSP90, PCNA, TP1, and TP2 genes expressions and the patterns of global DNA methylation were determined in all groups. A statistically significant (p less then 0.05) reduction were found in the HSP70-2a, HSP90, PCNA, TP1 and TP2 genes expressions in VCL-sole group. In VCLT group, testosterone was shown to significantly (p less then 0.05) up-regulate the HSP70-2a, HSP90, PCNA, and TP2expression levels, but TP1 expression has not been changed. Furthermore, the VCLT group exhibited higher DNA methylation rates compared to VCL-sole animals. In conclusion, testosterone, by up-regulating the HSP70-2a and HSP90 expressions and maintaining the pre-existing HSP70-2a and HSP90 proteins levels, may be the reason for the significant increment in TP2 expression during post-meiotic stage and can boost the global methylation rates of DNA via up-regulating the PCNA expression, suggesting that administration of testosterone can mitigate the VCL-impaired histone-protamine replacement and DNA methylation rates and protect the cellular DNA content from VCL-induced oxidative stress.
