A 72-year-old man with abdominal aortic aneurysm and angina pectoris underwent coronary artery bypass grafting (CABG) prior to abdominal aortic surgery. Perioperatively, he developed thrombocytopenia ((29,000 mm3), which was suggested as heparin-induced thrombocytopenia. Cardiac status was also aggravated at the same time, suggestive of bypass graft thrombosis. The results of platelet factor 4 (pf4) antibody test were negative, but platelet aggregation test was positive for heparin. Heparin was immediately discontinued, and replaced by argatroban;the patient’s cardiac status improved. One month later, he underwent abdominal aortic surgery using argatroban without issues related to anticoagulation and hemostasis. Autologous donated fresh blood prepared by the “switch-back” method was also used in this case, and its value was confirmed.

In most of the raw materials of plant origin used in animal feed, a portion of the phosphorus is stored as phytic acid or phytate. Phytate is the main storage form of phosphorus in vegetables but is not readily assimilated into food at low concentrations of the enzyme phytase. In addition to making phosphorous unavailable, phytate binds divalent cations such as calcium, copper, magnesium, iron, manganese and zinc, preventing the absorption of these nutrients in the gut of the animal. Phytase promotes the hydrolysis of the phytate phosphorus-releasing molecule, thereby increasing its bioavailability in feed. Phytase is distributed in plant and animal tissues and it is synthesized by some species of bacteria and fungi. The addition of this enzyme in the diet of animals is essential to promote greater uptake of phosphorus and also contributes to a decrease in the levels of phosphorus excreted by animals, thus reducing the pollution caused by excess phosphorus in the environment. This work aimed to select a fungus that stands out in the production of phytase among 100 isolates from Brazilian caves belonging to the genera Aspergillus, Penicillium and Cladosporium and 13 endophytic fungi of the aerial part of the coffee plant. For selection, the fungi were cultured in medium containing phytic acid as a sole source of phosphorus. After seven days at 25 °C, we evaluated growth and enzyme production by the presence of the phytic acid halo degradation (Enzymatic Index-ei) surrounding the colonies. Forty-seven species produced phytase, and the fungi Penicillium minioluteum (CF279) and Muscodor sp. (UBSX) showed higher degradation halos, 2.41 and 4.46, respectively. Considering the Muscodor sp. as the main source of phytase, high enzymatic levels were obtained when the fungus was grown under submerged fermentation with initial pH of 5.0 using wheat bran as additional carbon source for 144 h, at 125 rpm and 30 °C. Additionally, the enzyme was stable at pH 5.0 and 40 °C, and inhi

背景:西班牙四个城市9 家公共卫生治疗中心。目的:比较2 个月利福平+吡嗪酰胺(2RZ)与6 个月异烟肼(6H)治疗潜伏结核感染(LTBI),评估其效益及安全性。设计:对传染性肺结核病人的HIV(-)接触者进行多中心的前瞻性随机比较研究。结果:352 例中接受6H 者199 例,2RZ 者153 例;6H 组及2RZ 组治疗完成率各为73%及71%(P=0.73)。因肝毒性反应(AST 或ALT>5 倍正常上限值(ULN))而中断治疗者,2RZ 组为10%,6H 组为2.5%(P=0.007)。2RZ 组肝毒性反应高于期望发生率,因而未到期即终止了研究。停止治疗后肝功能均恢复正常。结论是RZ 方案只应用于不适用其它治疗方案者,且需有强化观察肝功能的条件。

Immersion Tools as a Strategy for Adolescents Mental Health: A Qualitative Study

Background: Information and communication technologies have revolutionized education, due to development of didactic strategies to take advantage of them for maximizing learning. The aim was to analyze the influence of immersion tools as a strategy to improve adolescents’ mental health. Methods: Qualitative research was employed, and participants’ experiences, opinions, values, behaviors, emotions, feelings were recorded. Twenty six students of both sexes, aged 13 to 15 years, from the three grades of secondary school were selected by convenience, and supported by the school’s psychologist. A workshop on emotional intelligence (ei) based on educational technology was implemented using a video;students practiced a reflexive process to understand themselves and their surroundings, creating a video + audio as a product of the workshop. In it, students analyzed several problems they face and their relationship with their contextual situation. Data collection was through semi-structured interviews before and after the workshop on ei. Data analysis was according to souza Minayo, and the theoretical framework according to Goleman, Tapia et al., Gorostieta et al., and Vigotsky. Results: Two categories emerged: Category I, ei as a risk factors transformer from living with addictions to protection factors in adolescents. Category II, ei development through immersion tools to improve mental health in adolescents. Conclusions: Immersion tools favor user to be closer, with a humanist focus where real necessities are studied after the vivid experience of the problem to solve or get a better situation. The goal is that students experience real situations inside controlled surroundings, in such a way that they learn from their experiences and acquire knowledge through self-learning. ei program through immersion tools favored to modulate feelings, and to get a bett
