BACKGROUND Fifty years ago, the groundbreaking British sketch series Monty Python's Flying Circus premiered on ****One and forever changed the world of comedy. The humour transcended mere absurdity by poking a subversive finger in the eye of buttoned-up British society. Here, we commemorate this cultural milestone and simultaneously call attention to an emerging concept in the health sciences, termed simplified peer review. The union of these disparate subjects motivates a formal gait analysis based on one of the troupe's most iconic sketches, "The Ministry of Silly Walks", a satire of bureaucratic inefficiency. https://www.selleckchem.com/products/enarodustat.html RESEARCH QUESTION The sketch portrays peer review as exceedingly efficient, lasting all of 20 s. But was it fair? The answer depends on how one measures silliness. If silly walking can be defined as deviations from typical walking, then it can be quantified using video-based gait analysis. METHODS To assess the quality of peer review at the Ministry of Silly Walks, we measured knee flexion in the sagittal plane of motion and calculated the Gait Variable Score (GVS) for three gait cycles, those of the Minister (n = 2) and Mr. Pudey (n = 1), an applicant for a Research Fellowship. RESULTS For the Minister, we found large deviations from typical walking across two gait cycles (GVSknee(1) = 33.6, GVSknee(2) = 23.3), whereas the gait of Mr Pudey produced an intermediate score (GVSknee = 16.3). By this measure, Mr Pudney's walk is 3.3 times more variable than typical walking, whereas an exemplary silly walk is 6.7 and 4.7 times more variable, respectively, than typical walking. SIGNIFICANCE Our analysis corroborates the Minister's assessment Mr Pudey is a promising applicant and deserving of a Research Fellowship to advance his silly walk. We suggest that the sketch holds special resonance and uncanny prescience for researchers in the health sciences today. V.During heterologous protein production with Escherichia coli, the formation of inclusion bodies (IBs) is often a major drawback as these aggregated proteins are usually inactive. However, different strategies for the generation of IBs consisting of catalytically active proteins have recently been described. In this study, the archaeal tetrameric coiled-coil domain of the cell-surface protein tetrabrachion was fused to a target reporter protein to produce fluorescent IBs (FIBs). As the cultivation conditions severely influence IB formation, the entire cultivation process resulting in the production of FIBs were thoroughly studied. First, the cultivation process was scaled down based on the maximum oxygen transfer capacity, combining online monitoring technologies for shake flasks and microtiter plates with offline sampling. The evaluation of culture conditions in complex terrific broth autoinduction medium showed strong oxygen limitation and leaky expression. Furthermore, strong acetate formation and pH changes from 6.5 to 8.8 led to sub-optimal cultivation conditions. However, in minimal Wilms-MOPS autoinduction medium, defined culture conditions and a tightly controlled expression were achieved. The production of FIBs is strongly influenced by the induction strength. Increasing induction strengths result in lower total amounts of functional protein. However, the amount of functional FIBs increases. Furthermore, to prevent the formation of conventional inactive IBs, a temperature shift from 37 °C to 15 °C is crucial to generate FIBs. Finally, the gained insights were transferred to a stirred tank reactor batch fermentation. Hereby, 12 g/L FIBs were produced, making up 43 % (w/w) of the total generated biomass. INTRODUCTION AND OBJECTIVE Every year cardiovascular disease (CVD) causes 3.9 million deaths in Europe. Portugal has implemented a set of public health policies to tackle CVD mortality a smoking ban in 2008, a salt reduction regulation in 2010 and the coronary fast-track system (FTS) for acute coronary syndrome (ACS) in 2007. Our goal in this study was to analyze the impact of these three public health policies in reducing case-fatality rates from ACS between 2000 and 2016. METHODS The impact of these policies on monthly ACS case-fatalities was assessed by creating individual models for each of the initiatives and implementing multiple linear regression analysis, using standard methods for interrupted time series. We also implemented segmented regression analysis to test which year showed a significant difference in the case-fatality slopes. RESULTS Separate modeling showed that the smoking ban (beta=-0.861, p=0.050) and the FTS (beta=-1.27, p=0.003) had an immediate impact after implementation, but did not have a significant impact on ACS trends. The salt reduction regulation did not have a significant impact. For the segmented model, we found significant differences between case-fatality trends before and after 2009, with rates before 2009 showing a steeper decrease. CONCLUSIONS The smoking ban and the FTS led to an immediate decrease in case-fatality rates; however, after 2009 no major decrease in case-fatality trends was found. Coronary heart disease constitutes an immense public health problem and it remains essential for decision-makers, public health authorities and the cardiology community to keep working to reduce ACS mortality rates. BACKGROUND Barriers to genetic testing and subsequent family cascade screening for familial hypercholesterolemia (FH) include cost, patient and provider awareness, privacy and discrimination concerns, need for a physician order, underutilization of genetic counselors, and family concerns about the implications of genetic testing for care. OBJECTIVES The objective of the study was to determine the uptake of genetic testing with cost and privacy removed. METHODS The FH Foundation offered free genetic testing and counseling to patients in the patient portal of the CASCADE FH Registry, who had not previously undergone genetic testing for 3 genes associated with FH (LDLR, APOB, and PCSK9). The free testing offer was extended to first-degree relatives of participants who had a positive genetic test result for cascade screening. RESULTS Of 435 eligible patients, 147 opted in to participate, 122 consented, and 110 (68.2% female, median age 52 years) received genetic testing. Of the participants, 64 had a positive genetic test result for a pathogenic variant in LDLR (59) or APOB (5); 11 had a variant of uncertain significance.
