Background: Pheochromocytomas (Pheo) are rare neuroendocrine tumors with a suggestive clinical picture, characterized by hypersecretion of catecholamines and other neuroendocrine biomarkers. Methods: The purpose of the study was to analyze the diagnostic features of Pheo and investigate the role played by different neuroendocrine and hormonal markers in diagnosing Pheo.The retrospective study involved a group of 69 patients diagnosed and treated with Pheo, who had both urinary and plasma catecholamines and neuroendocrine markers measured pre- and postoperatively. Results: After comparing pre- and postoperative hormonal parameters and neuroendocrine biomarker changes, numerous statistically significant findings were found. The analysis of the relationships between chromogranin A (CgA) levels, plasma and urine metanephrines, and normetanephrine and Pheo tumor size was included in the study. Additionally, we evaluated Cg A's diagnostic efficacy in comparison to plasma metanephrines, normetanephrine, and neuron-specific enolase (NSE) for Pheo. Conclusions: We obtained statistically significant data on pre- and postoperative differences for plasma and urinary catecholamines, CgA and NSE. Pheo tumor size is interdependent with serum levels of Cg A, plasma and urinary metanephrines, and normetanephrine. The best diagnostic power for Pheo was plasma normetanephrine, followed by plasma metanephrines and CgA.
背景:嗜铬细胞瘤(Pheo)是一种罕见的神经内分泌肿瘤,临床表现为儿茶酚胺和其他神经内分泌生物标志物的高分泌。方法:分析Pheo的诊断特点,探讨不同神经内分泌及激素指标在Pheo诊断中的作用。这项回顾性研究纳入了69名确诊并接受Pheo治疗的患者,他们在术前和术后都测量了尿和血浆儿茶酚胺和神经内分泌标志物。结果:在比较术前和术后激素参数和神经内分泌生物标志物的变化后,发现了许多具有统计学意义的发现。分析嗜铬粒蛋白A (CgA)水平、血浆和尿中肾上腺素、去甲肾上腺素与Pheo肿瘤大小的关系。此外,我们比较了血浆肾上腺素、去甲肾上腺素和神经元特异性烯醇化酶(NSE)对Pheo的诊断效果。结论:我们获得了具有统计学意义的血浆和尿儿茶酚胺、CgA和NSE术前和术后差异数据。Pheo肿瘤大小与血清Cg、血浆和尿中肾上腺素及去甲肾上腺素水平相关。血浆去甲肾上腺素是诊断Pheo的最佳指标,其次是血浆去甲肾上腺素和CgA。

": The term ""panniculitis"" refers to a heterogeneous group of conditions that involve inflammation of the subcutaneous cellular tissue. Although there is no universally accepted classification of panniculitis, to facilitate the diagnosis, they were divided into two large classes, based on the histopathological criteria: predominantly lobular and predominantly septal panniculitis. Depending on the presence or absence of vascular damage, each of the two classes mentioned above is divided in turn into panniculitis without vasculitis and panniculitis with vasculitis. The diagnosis of various types of panniculitis can sometimes be very difficult, due to the histopathological changes that occur in the various evolutionary stages of the lesions.

"The cytogenetic aberrations induced by doxorubicin (DOX) may be influenced by diet. Investigation regarding effects of low doses of DOX on chromosomal aberrations frequency in mice bone marrow. The study explored a possible relationship between diet, follow-up period, and cytostatic doses. Four mice groups received normal or high-fat (pork) diet. At the beginning of the 8th day mice from each group received a single intraperitoneal injection with DOX (dose range: 1.7-7.7 mg/kg b.w.) or isotonic saline solution (0.02 mL/g control mice). In the 10th (groups I, II) and 14th (groups III, IV) days from the beginning of the experiment, the mice were euthanized and chromosome aberrations were tested in bone marrow cells. The body weight of all mice who received DOX decreases, especially at higher doses. In the first three days post-injection, weight loss percentage was significantly influenced by DOX doses and/or type of diet (p<0.003). The interaction between the type of diet and DOX doses was not statistically significant in the follow-up period (p interactions >0.05). DOX doses were able to increase the frequency of chromosomal aberrations. DOX acts as a potent inductor of cytogenetic aberrations in bone marrow cells, regardless of the type of diet."

Background: The 12-lead electrocardiogram (ECG) is an extremely useful tool for analyzing cardiac arrhythmias and numerous ECG algorithms have been developed to predict the origin of right ventricular outflow tract (RVOT) arrhythmias. Aim: To determine if using complex, time-consuming analysis, and difficult-to-memorize ECG algorithms is feasible and preferable before the ablation procedure when compared with the use of multipolar mapping catheter use during the ablation procedure. Methods: 47 consecutive patients admitted for radiofrequency catheter ablation of idiopathic PVC were included prospectively in this study. Of the algorithms selected for comparison, three have a memorable design and easy applicability (Dixit, Joshi, Pytkowski) and the fourth has a complex, detailed design and is more difficult to memorize (Zhang). Results: The greatest accuracy was observed for the algorithms proposed by Dixit and Pytkowski – 92. 3%. However, when the algorithms were compared for their accuracy, specificity, and sensitivity, no significant differences were found (p=0. 96). Conclusions: 3-D guided mapping using a conventional ablation catheter in a narrower, precise area of interest in the RVOT, based on ECG algorithms is not inferior compared to the multielectrode catheter mapping in the whole RVOT, in terms of mapping time, total procedural time, and radiofrequency application time.
背景:12导联心电图(ECG)是一种非常有用的分析心律失常的工具,许多ECG算法已被开发用于预测右心室流出道(RVOT)心律失常的起源。目的:比较在消融过程中使用多极定位导管与在消融过程中使用多极定位导管相比,在消融前使用复杂、耗时且难以记忆的ECG算法是否可行和可取。方法:前瞻性研究纳入47例连续接受特发性PVC射频导管消融治疗的患者。在选择进行比较的算法中,有三个算法具有令人难忘的设计和易于应用(Dixit, Joshi, Pytkowski),而第四个算法具有复杂,详细的设计并且更难以记忆(Zhang)。结果:Dixit和Pytkowski - 92提出的算法精度最高。3%。然而,当比较算法的准确性、特异性和敏感性时,没有发现显著差异(p=0。96)。结论:基于ECG算法,在RVOT中更窄、更精确的兴趣区域使用传统消融导管进行三维引导测绘,在整个RVOT中,在测绘时间、总手术时间和射频应用时间方面,与多电极导管测绘相比并不逊色。

Introduction: Social responsibility and, is an indicator that is important in the epidemic of diseases with high prevalence and death rates. The current study aims at determining the relationship between social responsibility and COVID-19 in the population covered by health centers in Iran. Methods: 500 people participated in this descriptive-analytical study. The data was collected using a researcher-made social responsibility questionnaire in the context of the Covid-19 pandemic in three areas general, individual, and social responsibility. The quantitative content validity method was used to measure the validity of the questionnaire and Cronbach's alpha calculation method was used to measure its reliability. The data were analyzed using SPSS21 software. Findings: Among the participants, 4.32% of them had a history of covid-19, and the history of complications was more in men (51.9%) and the mean social responsibility score of women was higher (P<0.001). The average responsibility score was higher in people without a history of Covid-19 than in people with a history of Covid-19 (P=0.006). Conclusion: Individuals with higher social responsibility observed more health protocols and had lower rates of covid-19 infection among them. Therefore, in the design of educational interventions, planning should be done to increase people's sense of social responsibility.

According to the results of the study, there were determined the peculiarities of military values of servicemen who participated in hostilities and had signs of PTSD and moral trauma. The study included 397 servicemen (aged 20 to 55 years) with combat experience. The study showed that PTSD and violation of moral normativity were closely related to unfavorable social conditions of performing combat tasks. Unlike PTSD, the moral normativity indicator was less tightly related to the immediate threat to life. The structure of values of the servicemen had no signs of PTSD as well as no violation of moral normativity consisted of factors that indicated the value of teamwork, responsibilities for decisions and actions made based on ideas related to loyalty to the oath and the Motherland, resistance, and professionalism. For the servicemen who participated in hostilities who had violations of moral normativity, it was more important to have the ability to act following their conscience, not to lose dignity, and to remain honest in the faces of their brothers than to have professionalism, loyalty to the oath and the Motherland.
根据研究结果,确定了参与敌对行动并有创伤后应激障碍和道德创伤迹象的军人的军事价值观特点。这项研究包括397名有作战经验的军人(年龄在20至55岁之间)。研究表明,创伤后应激障碍和违反道德规范与执行作战任务的不利社会条件密切相关。与创伤后应激障碍不同,道德规范性指标与生命的直接威胁关系不那么紧密。军人的价值观结构没有创伤后应激障碍的迹象,也没有违反道德规范,这些因素表明了团队合作的价值、对基于忠于誓言和祖国、抵抗和专业精神的想法做出的决定和行动的责任。对于那些参与敌对行动、违反道德规范的军人来说,更重要的是有能力按照自己的良心行事,不失去尊严,在兄弟面前保持诚实,而不是有专业精神、忠于誓言和祖国。

"Clostridium difficile infection (CDI) is one of the most common healthcare-associated infections and an important cause of morbidity and mortality worldwide. The objective of the study was to identify the predictive factors for unfavorable evolution and deaths among patients with CDI. Materials and methods: We conducted a retrospective, observational, non-randomized study on 202 patients diagnosed with CDI in the Clinical Emergency Hospital of Bucharest, Romania, for a period of two years. For the statistical analysis, the R program was used, with p-values <0.05 being considered statistically significant. Results: The average age of the patients included in the study was 70.8 years, the average duration of hospitalization was 18.4 days, and the mortality rate was 25.7%. During the follow-up period, only 5% of the patients presented a recurrence of CDI.

The triglyceride-glucose index is a newly discovered parameter that indicates insulin resistance. This study aims to investigate the relationship between the triglyceride-glucose index and triglyceride/high-density lipoprotein ratio with glycemic control in patients with type 2 diabetes mellitus. This study was performed retrospectively in 296 patients with type 2 diabetes mellitus. Patients were divided into two equal groups according to their HbA1c levels as having good glycemic control (HbA1c 7 and below) and poor glycemic control (HbA1c above 7). Age, gender, body mass index, fasting blood glucose, HbA1c, total cholesterol, serum triglyceride level, serum HDL level, serum LDL level, riglyceride-glucose index, and triglyceride/HDL ratio were compared between the groups. Fasting blood glucose, HbA1c, triglyceride, HDL, triglyceride-glucose index, and triglyceride/HDL ratio wassignificantly different between patient groups with good and poor blood glucose regulation (p<0.05). Patients with poor glycemic control had lower fasting blood glucose, HbA1c, triglycerides, triglyceride-glucose index, and HDL values compared to patients with high triglyceride/HDL ratio and good glycemic control. There was no difference between the groups in terms of other variables (p>0.05). Triglyceride-glucose index and triglyceride/HDL ratio may be indicators of poor glycemic control in diabetic individuals. These indices are cheaper, universal, and easy-to-measure parameters compared to HbA1c and can be used to predict glycemic regulation.
甘油三酯-葡萄糖指数是新发现的胰岛素抵抗指标。本研究旨在探讨2型糖尿病患者甘油三酯-葡萄糖指数、甘油三酯/高密度脂蛋白比值与血糖控制的关系。本研究对296例2型糖尿病患者进行回顾性分析。将患者根据HbA1c水平分为血糖控制良好(HbA1c 7及以下)和血糖控制不良(HbA1c 7以上)两组,比较两组患者的年龄、性别、体重指数、空腹血糖、HbA1c、总胆固醇、血清甘油三酯水平、血清HDL水平、血清LDL水平、甘油三酯-葡萄糖指数、甘油三酯/HDL比值。空腹血糖、HbA1c、甘油三酯、HDL、甘油三酯-葡萄糖指数、甘油三酯/HDL比值在血糖调节良好组和血糖调节不良组间差异有统计学意义(p0.05)。甘油三酯-葡萄糖指数和甘油三酯/高密度脂蛋白比值可能是糖尿病患者血糖控制不良的指标。与HbA1c相比,这些指标更便宜、通用、易于测量,可用于预测血糖调节。
