Risk factors for acute pancreatitis in long-term drinking participants: a longitudinal UK Biobank-based study / 西安交通大学学报(医学版)

【Objective】 To examine risk factors for acute pancreatitis (AP) in individuals with chronic alcohol consumption habits. 【Methods】 The study incorporated participants from the initial survey (2006-2010) and subsequent follow-ups (2014+) taken from the UK Biobank database, with the observation period ending on November 30, 2022. During this period, 176 individuals were newly diagnosed with AP, while 59,512 remained unaffected. Vital characteristics of the target population, such as their medical histories, surgical experiences and dietary patterns, were collected during the enrolment phase (2006-2010). The Cox proportional hazard model was employed to ascertain whether these characteristics were potent risk factors for AP. Concurrently, a subgroup from the target population with documented drinking behavior was selected. The multivariate Cox proportional hazard model was utilized to analyze the relationship of the established factors, variances in alcohol consumption, and increased alcohol intake (Δ) with the onset of AP, and whether the additional alcohol intake served as a risk factor. 【Results】 Multivariate analysis revealed that consumption quantity of cooked vegetables inversely correlated with AP risk (HR=0.44, 0.39, 0.42 and 0.41 for one, two, three and four+ tablespoons per day, respectively, as compared to non-consumers). Coffee consumption (2-3 cups per day) also reduced AP risk (HR=0.45 for 2 cups/day; HR=0.39 for 3 cups/day as compared to non-coffee drinkers). However, those with biliary disease without cholecystectomy exhibited a marked increase in AP risk (HR=7.82), which reduced albeit remained elevated for those with biliary disease post-cholecystectomy (HR=2.15). Subgroup analysis showed minimal impact of alcohol intake levels on AP incidence. Yet, increased alcohol consumption (Δ of 1 bottle/week) was linked to a heightened AP risk (HR=1.05, 95% CI:1.02-1.09, P<0.05). 【Conclusion】 Among longstanding alcohol consumers, a diet rich in cooked vegetables and moderate coffee consumption offers protective effects against AP. Conversely, biliary disease (particularly without cholecystectomy) and elevated alcohol intake present considerable risk factors for the development of this condition.

Risk factors for cardiovascular disease in the Chinese population: recent progress and implications / 《全球健康杂志（英文）》

Cardiovascular disease (CVD) is the leading cause of death in both urban and rural areas of China. The current evidence regarding CVD risk factors was primarily established in Western countries, with limited generalizability to the Chinese population. In China, a growing number of population-based prospective cohort studies have emerged that have yielded substantial research data on CVD risk factors in the past five years. The research studies have covered biological risk factors (e.g., blood lipids, blood pressure, blood glucose, adiposity), lifestyle risk factors (e.g., smoking, alcohol, diet, physical activity), environmental risk factors (e.g., ambient and indoor air pollution), and risk prediction. This study aimed to systematically review the research progress on CVD risk factors in the Chinese population in the past five years. Prospective studies in China have identified biological, lifestyle, and environmental risk factors for CVD and its main subtypes, along with some protective factors unique to the Chinese (e.g., spicy food and green tea). This review aimed to provide high-quality evidence for achieving the Outline of Healthy China 2030, developing disease prevention guidelines and measures, and deepening efforts for popularization of health knowledge.

Use of the ACP® and BTS extenders for cooling at 15°C white-lipped peccary (Tayassu pecari) semen / Uso dos diluidores ACP® e BTS para refrigeração a 15°C de sêmen de queixada (Tayassu pecari)

Knowledge about reproduction of white-lipped peccary is of great importance to assist with the conservation of this species and enable its rational use in captivity. This study aimed to evaluate the effect of ACP-103®, ACP-116® and BTS semen extenders on sperm viability during cooling of Tayassu pecari semen. Five ejaculates from four adult males were chilled. The animals were submitted to the protocols of sedation and anesthesia for semen collection by the electroejaculation method. After collection, the semen was macro- and microscopically assessed and diluted to reach 35x106 spermatozoa/mL in each of the three different extenders tested. The fresh-extended semen was packed in a BotuFLEX® thermal box to keep samples at 15°C for 24 hours. After cooling, the following semen parameters were analyzed: sperm motility, functional and structural integrity of sperm membranes, mitochondrial activity, chromatin condensation, and the thermoresistance test was performed. The parameters sperm motility, structural and functional integrity of sperm membranes, mitochondrial activity, and chromatin condensation were preserved after use of the extenders tested, and were similar to those of in natura semen (p>0.05). Curvilinear velocity (VCL) (p<0.05) was the only parameter with reduced values after cooling regardless of the extender used. The percentage of sperm with normal morphology was greater in samples cooled using the BTS extender (p<0.05). The ACP-103®, ACP-116® and BTS extenders can be used for the cooling and preservation of white-lipped peccary semen at 15°C for 24 hours.(AU)

Para auxiliar na conservação da espécie e permitir o uso racional do queixada em cativeiro é de grande importância o conhecimento sobre a reprodução da espécie. Objetivou-se avaliar o efeito dos diluidores de sêmen ACP-103®, ACP-116® e BTS na viabilidade espermática durante a refrigeração do sêmen do Tayassu pecari. Foram refrigerados cinco ejaculados provenientes de quatro machos adultos. Os animais foram contidos com auxílio de puçá e submetidos ao protocolo de sedação e anestesia para realização da coleta de sêmen pelo método da eletroejaculação. Depois da coleta, o sêmen foi avaliado macro e microscopicamente e diluído para atingir 35x106 espermatozoides/mL em cada um dos três diferentes diluidores testados. O sêmen diluído foi acondicionado em caixa térmica BotuFLEX® para manter as amostras a 15°C por um período de 24 horas. Depois da refrigeração, os espermatozoides foram avaliados quanto aos parâmetros de movimento espermático, integridade funcional e estrutural das membranas espermáticas, atividade mitocondrial, condensação da cromatina e teste de termorresistência. Os diluidores testados preservaram as características cinéticas, a integridade estrutural e funcional das membranas espermáticas, a atividade mitocondrial e a condensação da cromatina semelhante ao sêmen in natura (P>0,05). O único parâmetro que reduziu com o processo de refrigeração independente do diluidor utilizado foi a Velocidade Curvilinear (VCL) (P<0,05). Foi observado aumento do percentual de espermatozoides morfologicamente normais nas amostras refrigeradas em BTS (P<0,05). Os diluidores ACP-103®, ACP-116® e BTS podem refrigerar e conservar o sêmen de queixada a 15°C por 24 horas.(AU)
