'Count your drinks' is a protective behavioural strategy (PBS) that has been found to be effective in reducing alcohol consumption. Previous research has shown that females, older people and low-risk drinkers are more likely to use this strategy, but little is known about the attitudinal factors associated with engaging in drink counting. This information is important for developing effective interventions to encourage use of this PBS. The aim of this paper was to assess whether the following attitudinal factors are associated with frequency of enactment of the 'Count your drinks' PBS (i) perceived ease of use; (ii) perceived effectiveness; (iii) personal relevance; and (iv) believability.

A total of 683 Australian drinkers completed an online survey assessing demographic variables, alcohol consumption, frequency of drink counting and attitudes to the 'Count your drinks' PBS. A hierarchical regression analysis was used to determine whether the attitudinal factors were associated with frequency of enactment after controlling for demographic and alcohol-related factors.

Attitudes to the 'Count your drinks' PBS accounted for 28% of the variance in reported frequency of drink counting. Perceptions of personal relevance, ease of use and effectiveness were found to be significantly associated with frequency of enactment.

Interventions designed to encourage drinkers to count their drinks should aim to increase the perceived personal relevance, ease of use and effectiveness of this strategy.

COVID-19 infection and acute endocarditis may present similarly, both with shortness of breath and vital sign abnormalities, yet they require very different treatments. Here, we present two cases in which life-threatening acute endocarditis was initially misdiagnosed as COVID-19 infection during the height of the pandemic in New York City. The first was a case of Klebsiella pneumoniae mitral valve endocarditis leading to papillary muscle rupture and severe mitral regurgitation, and the second a case of Streptococcus mitis aortic valve endocarditis with heart failure due to severe aortic regurgitation. These cases highlight the importance of careful clinical reasoning and demonstrate how cognitive errors may impact clinical reasoning. They also underscore the limitations of real-time reverse transcription-polymerase chain reaction (RT-PCR) for SARS-CoV-2 testing and illustrate the ways in which difficulty interpreting results may also influence clinical reasoning. Accurate diagnosis of acute endocarditis is critical given that surgical intervention can be lifesaving in unstable patients.Biphenotypic sinonasal sarcoma (BSNS) is a rare, low grade spindle cell sarcoma, recently recognized in the WHO classification of head and neck tumors, which is characterized by a dual myogenic and neural differentiation and recurrent gene fusions, often involving PAX3-MAML3, and less commonly PAX3 fusions with other partners such as NCOA1, NCOA2, or WWTR1. Yet, in about 4% of tumors no gene rearrangements are identified. Herein, we describe a RREB1-MKL2 fusion in a BSNS lesion occurring in a 73-year-old female patient with a right maxillo-ethmoidal angle lesion. The polypoid, moderately cellular tumor with infiltrative submucosal growth was composed of fascicles of relatively bland spindle cells embedded in a loose collagenous matrix. The tumor cells showed moderate amounts of eosinophilic cytoplasm with indistinct borders and uniform, pale, ovoid to slender nuclei. The slowly proliferating neoplastic cells co-expressed smooth muscle actin and S100, and showed focal nuclear positivity for ß-catenin, while lacking staining for cytokeratins, desmin, myogenin, caldesmon, glial fibrillary acid protein, and SOX-10. Molecular analysis by targeted RNA-based next-generation sequencing identified an in-frame fusion between exon 8 of RREB1 and exon 11 of MKL2, a genetic event that was reported to be a molecular hallmark of ectomesenchymal chondromyxoid tumor. Gene rearrangements in both genes were independently verified by fluorescence in situ hybridization (FISH). To evaluate its recurrent potential an additional group of 15 fusion negative BSNS were tested for abnormalities in RREB1 and MKL2 genes by FISH, but no additional positive cases were identified.Gene silencing using RNA interference (RNAi) has become a widely used genetic technique to study gene function in many organisms. In insects, this technique is often applied through the delivery of dsRNA. In the adult female Aedes aegypti, a main vector of human-infecting arboviruses, efficiency of gene silencing following dsRNA injection varies greatly according to targeted genes. Difficult knockdowns using dsRNA can thus hamper gene function analysis. Here, by analysing silencing of three different genes in female Ae. aegypti (p400, ago2 and E75), we show that gene silencing can indeed be dsRNA sequence dependent but different efficiencies do not correlate with dsRNA length. Our findings suggest that silencing is likely also gene dependent, probably due to gene-specific tissue expression and/or feedback mechanisms. We demonstrate that use of high doses of dsRNA can improve knockdown efficiency, and injection of a transfection reagent along with dsRNA reduces the variability in efficiency between replicates. Finally, we show that gene silencing cannot be achieved using siRNA injection in Ae. aegypti adult females. https://www.selleckchem.com/ Overall, this work should help future gene function analyses using RNAi in adult females Ae. aegypti, leading toward a better understanding of physiological and infectious processes.
Childhood obesity is a significant public health issue. Sugar-sweetened beverage (SSB) consumption contributes to this and adolescents are high consumers. This paper provides a descriptive overview of a school-based intervention to address this.

61 secondary schools in New South Wales were randomised to receive a behavioural intervention (BI), a chilled water station (CWS), both interventions or neither (control). The BI was delivered through classroom lessons, school-based promotion and vaccination clinic. The CWS intervention included the installation of one CWS per school. Intervention effectiveness over time was assessed via student surveys at baseline, post-intervention and follow-up (individual-level outcomes), feedback from teachers and vaccination nurses, a school information survey, and remotely monitored CWS water usage (school-level outcomes).

Teachers reported the BI was useful in teaching students about drinking water and negative consequences of SSBs. Nurses considered the post-vaccination waiting period a good opportunity to deliver health promotion messages.
