    Background This paper aimed to (i) update a previous typology of British alcohol drinking occasions using a more recent and expanded dataset and revised modelling procedure, and (ii) estimate the average consumption level, prevalence of heavy drinking, and distribution of all alcohol consumption and heavy drinking within and across occasion types. Methods The paper uses a cross-sectional latent class analysis of event-level diary data that includes characteristics of 43,089 drinking occasions in 2019 reported by 17,821 adult drinkers in Great Britain. The latent class indicators are characteristics of off-trade only (e.g. home), on-trade only (e.g. bar) and mixed trade (e.g. home and bar) drinking occasions. These describe companions, locations, purpose, motivation, accompanying activities, timings, consumption volume in units (1 UK unit = 8g ethanol) and beverages consumed. Results The analysis identified four off-trade only, eight on-trade only and three mixed-trade occasion types (i.e. latent classes). Mean consumption per occasion varied between 4.4 units in Family meals to 17.7 units in Big nights out with pre-loading. It exceeded ten units in all mixed-trade occasion types and in Off-trade get togethers, Big nights out and Male friends at the pub. Three off-trade types accounted for 50.8% of all alcohol consumed and 51.8% of heavy drinking occasions: Quiet drink at home alone, Evening at home with partner and Off-trade get togethers. For thirteen out of fifteen occasion types, more than 25% of occasions involved heavy drinking. Conversely, 41.7% of Big nights out and 16.4% of Big nights out with preloading were not heavy drinking occasions. Conclusions Alcohol consumption varies substantially across and within fifteen types of drinking occasion in Great Britain. Heavy drinking is common in most occasion types. However, moderate drinking is also common in occasion types often characterised as heavy drinking practices. Mixed-trade drinking occasions are particularly likely to involve heavy drinking

    BACKGROUND: Remote ischaemic conditioning with transient ischaemia and reperfusion applied to the arm has been shown to reduce myocardial infarct size in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). We investigated whether remote ischaemic conditioning could reduce the incidence of cardiac death and hospitalisation for heart failure at 12 months. METHODS: We did an international investigator-initiated, prospective, single-blind, randomised controlled trial (CONDI-2/ERIC-PPCI) at 33 centres across the UK, Denmark, Spain, and Serbia. Patients (age >18 years) with suspected STEMI and who were eligible for PPCI were randomly allocated (1:1, stratified by centre with a permuted block method) to receive standard treatment (including a sham simulated remote ischaemic conditioning intervention at UK sites only) or remote ischaemic conditioning treatment (intermittent ischaemia and reperfusion applied to the arm through four cycles of 5-min inflation and 5-min deflation of an automated cuff device) before PPCI. Investigators responsible for data collection and outcome assessment were masked to treatment allocation. The primary combined endpoint was cardiac death or hospitalisation for heart failure at 12 months in the intention-to-treat population. This trial is registered with ClinicalTrials.gov (NCT02342522) and is completed. FINDINGS: Between Nov 6, 2013, and March 31, 2018, 5401 patients were randomly allocated to either the control group (n=2701) or the remote ischaemic conditioning group (n=2700). After exclusion of patients upon hospital arrival or loss to follow-up, 2569 patients in the control group and 2546 in the intervention group were included in the intention-to-treat analysis. At 12 months post-PPCI, the Kaplan-Meier-estimated frequencies of cardiac death or hospitalisation for heart failure (the primary endpoint) were 220 (8·6%) patients in the control group and 239 (9·4%) in the remote ischaemic conditioning group (hazard ratio 1·10 [95% CI 0·91-1·32], p=0·32 for intervention versus control). No important unexpected adverse events or side effects of remote ischaemic conditioning were observed. INTERPRETATION: Remote ischaemic conditioning does not improve clinical outcomes (cardiac death or hospitalisation for heart failure) at 12 months in patients with STEMI undergoing PPCI.

    Objective: Inequalities in alcohol-related harm may arise partly from differences in drinking practices between population groups. One under-researched practice associated with harm is consuming alcohol alone. We identify sociodemographic characteristics associated with drinking alone and the occasion-level characteristics associated with occasions when people drink alone. Method: A cross-sectional analysis of one-week drinking diaries collected between 2015 and 2019 was conducted using event-level data on 271,738 drinking occasions reported by 83,952 adult drinkers in Great Britain. Our two dependent variables were a binary indicator of reporting at least one solitary drinking occasion in the diary-week at the individual-level and a binary indicator of drinking alone at the occasion-level (event-level). Results: Individual-level characteristics associated with solitary drinking were being a man (OR 1.88, 95%CI [1.80,1.96]), aged over 50 (OR 2.60, 95%CI [2.40,2.81]), not in a relationship (OR 3.39, 95%CI [3.20, 3.59]), living alone (OR 2.51, 95%CI [2.37, 2.66]), and a high-risk drinker (OR 1.54, 95%CI [1.52,1.59]). Occasion-level characteristics associated with solitary drinking were that they were more likely to occur in the off-trade (OR 3.08, 95%CI [2.95,3.21]), Monday-Thursday (OR 1.36, 95%CI [1.27,1.47]), and after 10pm (OR 1.36, 95%CI [1.27,1.47]) controlling for geographic region and the month the interview took place. Conclusions: Characteristics of solitary drinking largely align with characteristics we associated with drinking problems. Those who partake in at least one solitary drinking occasion are overall more likely to consume alcohol at risky levels, however, the number of drinks consumed in each occasion was lower during a solitary drinking occasion

    Visión etnográfica y percepción de actores sociales en Pahuatlán de Valle, Puebla: un estudio alimentario

    Este trabajo de investigación fue realizado por alumnos de la licenciatura en Gastronomía de la Universidad del Claustro de Sor Juana, en el área de desarrollo de Investigación y Difusión de la Gastronomía . El proyecto se planeo para formarlos en las materias de Investigación de campo e Investigación documental; los alumnos aprenderían a estructurar su pensamiento para poder seguir rigurosamente metodología cualitativa, necesaria para el desarrollo de una investigación de calidad, desde la complejidad y la disciplina que esta actividad demanda. Se eligió el municipio Pahuatlán, Puebla porque conjunta la presencia de tres grupos étnicos: nahuas, otomíes y mestizos. Además de ser expulsor de mano de obra a Estados Unidos y presentar importantes índices de pobreza. Se diseñó un estudio alimentario de las cocinas y productos alimentarios tradicionales y locales entre los grupos sociales y étnicos, ayudándonos de entrevistas, observaciones participantes y cuestionarios; esto con la finalidad de darnos ideas de las costumbres alimentarias que existen en los diferentes grupos y ejemplificar para el municipio con la finalidad de alejar el típico concepto de gastrónomo que, para muchos, es igual a cocinero; para mostrar documentalmente la calidad del trabajo de lo que nosotros nos jactamos que pueden ser los gastrónomos con formación universitaria humanista que entienden al fenómeno de la alimentación como un hecho social, cultural, económico y biológico. Es poco conocido que el gastrónomo no es sólo aquél que se encarga de la creación culinaria; es, también al que le preocupan y le ocupan las costumbres alimentarias del otro. Esta investigación sería un conjunto de propuestas por definir conceptos que se usan a diestra y siniestra sin acotar pertinentemente su significado con argumentos sólidos. Por eso, era nuestra intención delimitar conceptos como cocina étnica, tradicional y regional

    Triosephosphate isomerase (TPI) is a glycolysis enzyme, which catalyzes the reversible isomerization between dihydroxyactetone-3-phosphate (DHAP) and glyceraldehyde-3-phosphate (GAP). In pathogenic organisms, TPI is essential to obtain the energy used to survive and infect. Fusarium oxisporum (Fox) is a fungus of biotechnological importance due to its pathogenicity in different organisms, that is why the relevance of also biochemically analyzing its TPI, being the first report of its kind in a Fusarium. Moreover, the kinetic characteristics or structural determinants related to its function remain unknown. Here, the Tpi gene from F. oxysporum was isolated, cloned, and overexpressed. The recombinant protein named FoxTPI was purified (97% purity) showing a molecular mass of 27 kDa, with optimal activity at pH 8.0 and and temperature of 37 °C. The values obtained for Km and Vmax using the substrate GAP were 0.47 ± 0.1 mM, and 5331 μmol min−1 mg−1, respectively. Furthemore, a protein structural modeling showed that FoxTPI has the classical topology of TPIs conserved in other organisms, including the catalytic residues conserved in the active site (Lys12, His94 and Glu164). Finally, when FoxTPI was analyzed with inhibitors, it was found that one of them inhibits its activity, which gives us the perspective of future studies and its potential use against this pathogen
