Objective: To examine self‐reported alcohol consumption and relationships between consumption, awareness of the 2009 NHMRC guidelines of no more than two standard drinks per day, drinking in excess of the guideline threshold and perceptions of alcohol as a risk factor for cancer. Methods: Questions were included in annual, cross‐sectional surveys of approximately 2,700 South Australians aged 18 years and over from 2004 to 2012. Consumption data for 2011 and 2012 were merged for the majority of analyses. Results: In 2011 and 2012, 21.6% of adults drank in excess of the guideline threshold (33.0% males; 10.7% females). While 53.5% correctly identified the NHMRC consumption threshold for women, only 20.3% did so for men (39.0% nominated a higher amount). A large minority said they did not know the consumption threshold for women (39.2%) or men (40.4%). In 2012, only 36.6% saw alcohol as an important risk factor for cancer. Important predictors of excess consumption for men were: higher household income; and not perceiving alcohol as an important risk factor for cancer. Predictors for women were similar but the role of household income was even more prominent. Conclusions: Men were nearly three times as likely to drink in excess of the guidelines as women. The majority of the population did not see an important link between alcohol and cancer. Awareness of the latest NHMRC guidelines consumption threshold is still low, particularly for men. Implications: A strategy to raise awareness of the NHMRC guidelines and the link between alcohol and cancer is warranted. 相似文献

Background
Gastric cancer (GC) is a progressive process initiated by Helicobacter pylori-induced inflammation. Initial recognition of H. pylori involves Toll-like receptors (TLRs), central molecules in the host inflammatory response. Here, we investigated the association between novel polymorphisms in genes involved in the TLR signalling pathway, including TLR2, TLR4, LBP, MD-2, CD14 and TIRAP, and risk of H. pylori infection and related GC.Methods
A case-control study comprising 310 ethnic Chinese individuals (87 non-cardia GC cases and 223 controls with functional dyspepsia) was conducted. Twenty-five polymorphisms were detected by MALDI-TOF mass spectrometry, PCR, PCR–RFLP and real-time PCR.Results
Seven polymorphisms showed significant associations with GC (TLR4 rs11536889, TLR4 rs10759931, TLR4 rs1927911, TLR4 rs10116253, TLR4 rs10759932, TLR4 rs2149356 and CD14 −260 C/T). In multivariate analyses, TLR4 rs11536889 remained a risk factor for GC (OR: 3.58, 95% CI: 1.20–10.65). TLR4 rs10759932 decreased the risk of H. pylori infection (OR: 0.59, 95% CI: 0.41–0.86). Statistical analyses assessing the joint effect of H. pylori infection and the selected polymorphisms revealed strong associations with GC (TLR2, TLR4, MD-2, LBP and TIRAP polymorphisms).Conclusions
Novel polymorphisms in TLR2, TLR4, MD-2, LBP, CD14 and TIRAP, genes encoding important molecules of the TLR signalling pathway, showed clear associations with H. pylori-related GC in Chinese. 相似文献3.

While there is an increasing number of toxicity report cases and toxicological studies on Chinese herbal medicines, the guidelines for toxicity evaluation and scheduling of Chinese herbal medicines are lacking.Aim
The aim of this study was to review the current literature on potentially toxic Chinese herbal medicines, and to develop a scheduling platform which will inform an evidence-based regulatory framework for these medicines in the community.Materials and methods
The Australian and Chinese regulations were used as a starting point to compile a list of potentially toxic herbs. Systematic literature searches of botanical and pharmaceutical Latin name, English and Chinese names and suspected toxic chemicals were conducted on Medline, PubMed and Chinese CNKI databases.Results
Seventy-four Chinese herbal medicines were identified and five of them were selected for detailed study. Preclinical and clinical data were summarised at six levels. Based on the evaluation criteria, which included risk–benefit analysis, severity of toxic effects and clinical and preclinical data, four regulatory classes were proposed: Prohibited for medicinal usage, which are those with high toxicity and can lead to injury or death, e.g., aristolochia; Restricted for medicinal usage, e.g., aconite, asarum, and ephedra; Required warning label, e.g., coltsfoot; and Over-the-counter herbs for those herbs with a safe toxicity profile.Conclusion
Chinese herbal medicines should be scheduled based on a set of evaluation criteria, to ensure their safe use and to satisfy the need for access to the herbs. The current Chinese and Australian regulation of Chinese herbal medicines should be updated to restrict the access of some potentially toxic herbs to Chinese medicine practitioners who are qualified through registration. 相似文献4.
Obesity is a serious risk factor for chronic disease, and commonly prescribed oral glucocorticoids (OCS) may be contributing to the prevalence of obesity. The objective of this review was to assess the impact of OCS on obesity in humans through effects on body weight (BW), energy intake, appetite, and body composition. An electronic search of English language peer-reviewed studies from 1973 up to March 2012 was conducted using Medline, CINAHL, EMBASE, and Cochrane databases. Original studies that addressed the effects of OCS on appetite, energy intake, BW, or body composition in adults were considered eligible. Data from 21 studies with objectively measured outcomes were extracted and assessed for quality using standardized tools. The publication year varied from 1986 to 2013, and the sample size, from 6 to 189. Energy intake was measured in 6 studies; BW, in 19 studies; energy expenditure, in 3 studies; body composition, in 6 studies; and appetite was evaluated in 3 studies. Short-term oral glucocorticoid therapy may result in small increases in energy intake but does not appear to result in increased BW, possibly due to an increase in energy expenditure. Long-term therapy may result in clinically significant weight gain. Within-subject variation due to metabolism and physical activity levels confounds the relationship. A dose-response relationship of oral glucocorticoid therapy on energy intake, appetite, BW, or body composition was not found. Additional well-designed, double-blind, placebo-controlled clinical trials that use standardized doses of OCS and assess the effects on appetite, energy intake, BW, and composition are strongly justified to confirm the findings of this review. 相似文献

Cutaneous head and neck tumors mainly comprise malignant melanoma, squamous cell carcinoma, trichoblastic carcinoma, Merkel cell carcinoma, adnexal carcinoma, dermatofibrosarcoma protuberans, sclerodermiform basalioma and angiosarcoma. Adapted management requires an experienced team with good knowledge of the various parameters relating to health status, histology, location and extension: risk factors for aggression, extension assessment, resection margin requirements, indications for specific procedures, such as lateral temporal bone resection, orbital exenteration, resection of the calvarium and meningeal envelopes, neck dissection and muscle resection. 相似文献

The aim of this study was to investigate the in vivo relationship between reelin and NMDA receptor function in schizophrenia. We assessed the effect of reelin deficiency in behavioral models of aspects of this illness, NMDA receptor subunit levels, and NMDA receptor, dopamine D2 receptor, and dopamine transporter density. Male, but not female, reelin heterozygous mice showed significantly enhanced MK-801-induced locomotor hyperactivity compared to wildtype controls (7.4-fold vs. 5.2-fold effect of MK-801 over saline, respectively) but there were no genotype differences in the response to amphetamine. Both male and female reelin heterozygous mice showed enhanced effects of MK-801 on startle, but not prepulse inhibition (PPI) of startle. There were no group differences in the effect of apomorphine on startle or PPI. The levels of NMDA receptor subunits were not altered in the striatum. In the frontal cortex, male and female reelin heterozygous mice showed significant up-regulation of NR1 subunits, but down-regulation of NR2C subunits, which was associated with significantly elevated NR1/NR2A and NR1/NR2C ratios. However, there were no differences in [3H]MK-801 binding density in the nucleus accumbens or caudate nucleus, nor in the density of [3H]YM-09151 or [3H]GBR12935 in these brain regions. The enhanced effects of MK-801 in reelin heterozygous mice in this study could be reflective of the role of reelin deficiency in schizophrenia. This genotype effect was male-specific for locomotor hyperactivity, a model of psychosis, but was seen in male and female mice for startle, which could be an indication of changes in anxiety. Changes in NMDA receptor subunit levels and ratios were also seen in both male and female mice. These results suggest that the role of reelin deficiency in schizophrenia may be particularly mediated by altered NMDA receptor responses, with some of these effects being strictly sex-specific. 相似文献

Introduction
Despite vancomycin being in use for over half-a-century, it is still not dosed or monitored appropriately in many centers around the world. The objective of this study was to determine the effectiveness of a multifaceted intervention to implement a vancomycin dosing and monitoring guideline across multiple medical and surgical units over time.Methods
This was an observational before-and-after interventional cohort study. The pre-intervention period was August to December 2010–2011 and the post-intervention period was September to November 2012–2014. The implementation strategy comprised: face-to-face education, online continuing medical education, dissemination of pocket guideline and email reminder. Outcome measures included: appropriate prescribing of loading and maintenance doses, therapeutic drug monitoring, time to attain target range and nephrotoxicity.Results
Post-implementation prescribing of loading doses increased (10.4%–43.6%, P=<0.001), guideline adherent first maintenance dose (44%–68.4% P = 0.04), correct dose adjustment from (53.1%–72.2%, P = 0.009). Beneficial effects pre and post-implementation were observed for adherent timing of initial concentration (43.2%–51.9%, P = 0.01), concentrations in target range (32.6%–44.1%, P = 0.001), time to target range (median 6–4 days, P=<0.001), potentially nephrotoxic concentrations (30.7%–20.9%, P=<0.001) and nephrotoxicity (10.4%–6.8%, P=<0.001).Conclusions
A multifaceted intervention to implement a vancomycin dosing and monitoring guideline significantly improved prescribing, monitoring, pharmacokinetic and safety outcomes for patients treated with vancomycin over an extended period. However, increased guideline adoption by clinicians is required to maximize and prolong the utility of this important agent. 相似文献10.
