The diagnosis of liver cirrhosis in patients with chronic hepatitis C has not always been easy, since the gold standard method is the liver biopsy, which is an invasive procedure with interobserver accuracy problems and there have been reports of complications including records of deaths due to hemoperitoneum. Cirrhosis changes the prognosis of the subject with hepatitis C and requires a different clinical management. This study aimed to identify clinical and laboratory variables associated with the diagnosis of cirrhosis in the ultrasonography of patients infected with hepatitis C. In a case-control study, we evaluated 70 cirrhotic patients with chronic hepatitis C compared to a control group of 70 non-cirrhotic people with positive HCV. The results showed, through logistic regression analysis, that the variables blood donor and professional athlete, adjusted for alcohol consumption, showed OR 0.24 and 0.18, with p values of 0.044 and 0.035, respectively. We conclude that the diagnosis of cirrhosis in patients with chronic hepatitis C remains challenging, but the patients with the condition of blood donor or professional athlete prove to be less likely to cirrhosis in ultrasonography in the initial consultation.

AIM To evaluate the effect of a 12-mo supervised aerobic and resistance training, on renal function and exercise capacity compared to usual care *** Ninety-nine kidney transplant recipients(KTRs) were assigned to interventional exercise(Group A; n = 52) and a usual care cohort(Group B; n = 47). Blood and urine chemistry, exercise capacity, muscular strength, anthropometric measures and health-related quality of life(HRQo L) were assessed at baseline, and after 6 and 12 mo. Group A underwent a supervised training three times per week for 12 mo. Group B received only general recommendations about home-based physical *** Eighty-five KTRs completed the study(Group A, n = 44; Group B, n = 41). After 12 mo, renal function remained stable in both groups. Group A significantly increased maximum workload(+13 W, P = 0.0003), V'O2 peak(+3.1 mL/kg per minute, P = 0.0099), muscular strength in plantar flexor(+12 kg, P = 0.0368), height in the countermovement jump(+1.9 cm, P = 0.0293) and decreased in Body Mass Index(-0.5 kg/m^2, P = 0.0013). HRQo L significantly improved in physical function(P = 0.0019), physical-role limitations(P = 0.0321) and social functioning scales(P = 0.0346). Noimprovements were found in Group *** Twelve-month of supervised aerobic and resistance training improves the physiological variables related to physical fitness and cardiovascular risks without consequences on renal function. Recommendations alone are not sufficient to induce changes in exercise capacity of KTRs. Our study is an example of collaborative working between transplant centres, sports medicine and exercise facilities.

试验在育肥羔羊日粮中添加绿色蜂胶、棕色蜂胶以及莫能菌素钠,研究其对羔羊的行为和生产性能的影响。试验采用随机区组设计,选取4月龄公羔羊32只,随机分为4个处理组。各处理组的试验日粮设计为:对照组为基础日粮、基础日粮中添加绿色蜂胶、基础日粮中添加棕色蜂胶、基础日粮中添加莫能菌素钠。各处理组中基础日粮为全混合日粮(TMR)精粗比为50:50,粗饲料以苏丹草85(狗牙根属)为主要成分,浓缩料以豆粕、玉米粉和矿物质为主要成分。试验研究表明,日粮中添加绿色蜂胶可以减少反刍并增加休息时间,与对照组相比能提供相同的采食率(g·min-1),DM和Andf摄入量均高于对照组。对照组的体增重最高,但饲养过程中发现棕色蜂胶和莫能菌素钠处理组的饲料转化率和饲料利用效率最高。试验证明,棕色蜂胶可以替代莫能菌素钠作为育肥羔羊日粮添加剂。然而,为达到增加采食量的目的,确定棕色蜂胶最佳添加水平需要进一步研究。

人们观测到亚马逊森林大火的浓烟减小了云滴的大小,使降水产生延迟。因为清洁云在云底以上1.5km处就可以产生降水,而被污染的云中这个高度要抬升到5km以上,在火成云中就要到7km以上了。云中低层被抑止的降雨和气溶胶沉降使得水份和烟尘向高层输送,高层的云就像能卸下很多污染物的'烟'。在抬高了的降雨启动高度上,由于相变触发的上升气流导致强的雷雨、大雹以及其他类似的云体突破云顶进入平流层,在平流层沉降的污染物和水汽的辐射效应对气候系统有深刻的影响。大气中激发的风暴在更高层释放出潜热,这就从本质上影响了区域和全球的环流系统。这些过程共同影响了水份循环、大气中污染物的分布以及大气环流的动力学特征。

The objective of this work was to verify the responses in agronomic and physiological characters of lettuce seedlings when submitted to different doses of humic acids and the presence or absence of inoculation of the bacterium Azospirillum brasilense. The experiment was carried out at the Protected Cultivation Station and Biological Control Teacher Mário César Lopes, belonging to the Experimental Stations Nucleus of the State University of the West of Paraná. The experimental design was a randomized block design, in a 5 × 2 factorial scheme, with four repetitions, totaling 40 plots. The first factor consisted of five solutions containing humic acid (100%, 75%, 50%, 25% and 0%) and the second factor was the presence or absence of the diazotrophic bacterium Azospirillum brasilense obtained by commercial product. Germination tests were carried out in addition to the determination of agronomic characters such as the number of fully expanded leaves, plant height, stem diameter, main root length, shoot dry mass, root dry mass, total dry mass, and Dickson quality index. The association of diazotrophic bacteria and humic acids did not influence the emergency rate, mean emergence time, mean speed of emergency, emergence speed index, plant height, and root length of lettuce seedlings. The dilutions of humic acids, regardless of inoculation with bacteria diazotrophic favored the development of the number of leaves, stem diameter and Dickson quality index. Inoculation of lettuce seeds with diazotrophic bacteria associated with the addition of humic acids, favored the development of the dry mass of root and total dry matter.

Introduction: At the beginning of the COVID-19 pandemic, a drop in the number of patients treated for cardiac emergencies raised concern about cardiovascular mortality in that period. An increase in care delay for patients with ST-segment elevation myocardial infarction (STEMI) may have affected clinical outcomes. Objectives: To analyze delay times and clinical outcomes of patients with STEMI undergoing primary percutaneous coronary intervention (PPCI), before and during the COVID-19 pandemic. Methods: Retrospective observational study that included patients with STEMI undergoing PPCI from December 2018 to July 2021. The COVID-19 pandemic cases were divided into two groups: pandemic I—from March to August 2020;and pandemic II—from September 2020 to July 2021. Patients were compared according to the period of hospitalization. Primary outcomes were delay times in assistance and clinical outcomes (acute kidney injury [AKI], post-procedural vascular complications and in-hospital mortality). Results: 108 patients were included, 39 (36.1%) in the pre-pandemic period, 13 (12.1%) in pandemic I and 56 (51.8%) in pandemic II. Time from onset of symptoms to arrival at the service and door-to-balloon time did not differ significantly among groups. Vascular complications were more frequent during the pandemic (I and II) than in the pre-pandemic period (2.5% pre-pandemic vs 15.4% pandemic vs 12.5% pandemic II;p = 0.03). AKI incidence was similar in all three periods. There was a non-significant increase in in-hospital mortality during the COVID-19 pandemic. Conclusion: In patients with STEMI, there was an increase in vascular complications and a trend toward increased mortality during the COVID-19 pandemic. Delay times to admission and reperfusion did not differ significantly between before and during the pandemic.
