The coronavirus disease COVID-19 is characterized by high mortality and the lack of effective etiotropic therapy. Activation of oxidative stress may be one of the links in the pathogenesis of organ damage of this infection. Objective. To assess the ability of Mexidol® to influence the rate of clinical improvement in pneumonia caused by the SARSCoV-2 virus in hospitalized patients with the novel coronavirus disease COVID-19 and concomitant discirculatory encephalopathy. 62 patients over the age of 18 years with confirmed new coronavirus disease COVID-19 according to computed tomography (CT) of the lungs (stages CT1, CT2, CT3) and PCR of a swab from the nasopharynx and oropharynx for SARS-CoV-2 virus RNA were included. After randomization patients of group 1 received an infusion of Mexidol® at a dose of 1000 mg/day, patients of group 2 – an infusion of isotonic sodium chloride solution for 7 days. Compared with the control group, the patients receiving Mexidol® therapy showed a significantly more pronounced decrease in body temperature, a tendency towards a decrease in the severity of shortness of breath. In the Mexidol® group, the concentration of superoxidedismutase did not change, while in the control group there was a tendency to its decrease, C-reactive protein decreased 2.2 times more than in the control group (p = 0.09). There was a tendency for a more rapid decrease in ferritin in the active intervention group. Mexidol® therapy can have a positive effect on the clinical manifestations and severity of laboratory-inflammatory syndrome in patients with the new coronavirus disease COVID-19. Key words: coronavirus disease COVID-19, oxidative stress, Mexidol

Few Data

Oxidative stress (OS) is increased in chronic diseases, including cardiovascular (CV), but there are few data on its effects on the heart and vessels. The isoprostanes (IsoP) are bioactive compounds, with 8-iso-PGF25a being the most representative in vivo marker of OS. They correlate with the severity of heart failure (HF), but because data regarding OS levels in different types of HF are scarce, our study was aimed to evaluate it by assessing the urinary levels of 8-iso-PGF2aand its correlations with various biomarkers and parameters. Our prospective study included 53 consecutive patients with HF secondary to ischemic heart disease or dilative cardiomyopathy, divided according to the type of HF (acute, chronic decompensated or chronic compensated HF). The control group included 13 hypertensive patients, effectively treated. They underwent clinical, laboratory - serum NT-proBNP, creatinine, uric acid, lipids, C reactive protein (CRP) and urinary 8-iso-PGF2a and echocardiographic assessment. HF patients, regardless the type of HF, had higher 8-iso-PGF2a than controls (267.32pg/�mol vs. 19.82pg/�mol, p[0.001). The IsoP level was directly correlated with ejection fraction (EF) (r=-0.31, p=0.01) and NT-proBNP level (r=0.29, p=0.019). The relative wall thickness (RWT) was negatively correlated with IsoP (r=-0.55, p[0.001). Also 8-iso-PGF25a was higher by 213.59pg/�mol in the eccentric left ventricular (LV) hypertrophy subgroup comparing with the concentric subgroup (p=0.014), and the subgroups with severe mitral regurgitation (MR) and moderate/severe pulmonary hypertension (PAH) had the highest 8-iso-PGF2a levels. Male sex, severe MR, moderate/severe PAH, high LV mass and low RWT values were predictive for high OS level in HF patients.Eccentric cardiac remodeling, MR severity and PAH severity are independent predictors of OS in HF patients.

Aim: In cyclosporin-A (CsA)-induced toxicity, oxidative stress has been implicated as a potential responsible mechanism. Therefore, we aimed to investigate the protective role of erdosteine against CsA-induced nephrotoxicity in terms of tissue oxidant/antioxidant parameters and light microscopy in rats. Materials and methods: Wistar albino rats were randomly separated into four groups. Group 1 rats treated with sodium chloride served as the control, group 2 rats were treated with CsA, group 3 with CsA plus erdosteine, and group 4 with erdosteine alone. Animals were killed and blood samples were analyzed for blood urea nitrogen (BUN), serum creatinine (Cr), uric acid (UA), total protein (TP), and albumin (ALB) levels. Kidney sections were analyzed for malondialdehyde (MDA) and nitric oxide (NO) levels and superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) activities, as well as for histopathological changes. Results: In the CsA group, MDA, GSH-Px, BUN, and Cr levels were increased. The TP and ALB levels were decreased. These changes had been improved by erdosteine administration. Other biochemical parameters did not show any significant change. Conclusion: These results indicate that erdosteine produces a protective mechanism against CsA-induced nephrotoxicity and suggest a role of oxidative stress in pathogenesis.

Background: C-reactive protein test is one of clinical assessments to minimize risks of infection in infants. However, its procedure may cause pain. Pain in the infant may result in negative metabolic behavior, physiology and metabolic response. Objective: This study was to describe the infant's pain response by administering a combination of breastfeeding and an effleurage massage on the blood sampling procedure of C-reactive protein examination.         Methods: This was a descriptive observational cross-sectional study. There were 30 infants selected using consecutive sampling technique, which 15 samples assigned in an intervention group (combination of breastfeeding and effleurage massage) and a control group. Premature Infant Pain Profile (PIPP) instrument was used to measure pain. Univariate analysis was performed with the aim to describe data in mean and median.Results: The average of pain response at 1-minute observation in the combination of breastfeeding and effleurage massage group was 7.47 ± 1.356, and the average of pain response in the control group was 10.80 ± 1.897. The average pain at 5-minutes in the intervention group was 3.53 ± 1.922 and control group was 6.00 ± 1.852. Conclusions: Pain responses in the combination of breastfeeding and effleurage massage group were lower than the pain response in the control group.

Cadmium (Cd) is a toxic non-essential element, while calcium (Ca) is an essential element with high chemical similarity to Cd. Dietary intake is the major Cd exposure pathway for non-smokers. A multi-concentration dietary intervention experiment was designed to explore the optimum concentration of Ca in diet with obvious protective effects against the toxicity of livers and kidneys induced by Cd in mice. The mice were divided into six groups with different concentrations of Cd and Ca in their food: control-group (no Cd or Ca), Ca-group (100 g/kg Ca, without Cd), Cd-group (2 mg/kg Cd, without Ca), CaL+Cd-group (2 mg/kg Cd, 2 g/kg Ca), CaM+Cd-group (2 mg/kg Cd, 20 g/kg Ca) and CaH+Cd-group (2 mg/kg Cd, 100 g/kg Ca). The organ indexes, oxidative stress biomarkers, lesions and Cd concentrations were detected after a 30-day exposure period. Results showed that serum Aspartate Aminotransferase (AST) level in CaH+Cd-group was significantly lower than that in Cd-group, while close to that in control-group. The contents of Serum Blood Urea Nitrogen (BUN) in different groups showed the same trend. Concentrations of all oxidative stress biomarkers (GSH-Px, SOD, CAT, GSH and MDA) in CaH+Cd-group were close to the normal levels of control-group while significantly different from those in Cd-group. The only exception was the Malondialdehyde (MDA) levels in kidneys. This study suggests that Ca plays a protective role in relieving the Cd-induced toxicity of livers and kidneys and a concentration of 100 g/kg for Ca in diet showed the best protective effects. These findings could provide a clue for further studies concerning human diet intervention for Cd control.

AbstractThe outbreak of the novel coronavirus disease 2019 (COVID-19) infection began in December 2019 in Wuhan, and rapidly spread to many provinces in China. The number of cases has increased markedly in Anhui, but information on the clinical characteristics of patients is limited. We reported 75 patients with COVID-19 in the First Affiliated Hospital of USTC from Jan 21 to Feb 16, 2020, Hefei, Anhui Province, China. COVID-19 infection was confirmed by real-time RT-PCR of respiratory nasopharyngeal swab samples. Epidemiological, clinical and laboratory data were collected and analyzed. Of the 75 patients with COVID-19, 61 (81.33%) had a direct or indirect exposure history to Wuhan. Common symptoms at onset included fever (66 [88.0%] of 75 patients) and dry cough (62 [82.67%]). Of the patients without fever, cough could be the only or primary symptom. The most prominent laboratory abnormalities were lymphopenia, decreased percentage of lymphocytes (LYM%), decreased CD4+ and CD8+ T cell counts, elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH). Patients with elevated interleukin 6 (IL-6) showed significant decreases in the LYM%, CD4+ and CD8+ T cell counts. Besides, the percentage of neutrophils, CRP, LDH and Procalcitonin levels increased significantly. We concluded that COVID-19 could cause different degrees of hematological abnormalities and damage of internal organs. Hematological profiles including LYM, LDH, CRP and IL-6 could be indicators of diseases severity and evaluation of treatment effectiveness. Antiviral treatment requires a comprehensive and supportive approach. Further targeted therapy should be determined based on individual clinical manifestations and laboratory indicators.

Rapid development in information and communication technology (ICT) is changing the instructional strategies in Higher Education. This study aimed to identify the level of self-efficacy of B.Ed. (IT) undergraduates of a local University in a flipped classroom. Further it also investigated gender difference among the undergraduates self-efficacy in the classroom. A group of 35 student selected using convenience sampling method. This group divided into Group 1 as control group and Group 2 as intervention. Group one consists of 17 students and two consist of 18 students. Initially the two classes answered pre-survey questionnaire of self-efficacy. Then control group was exposed to conventional teaching whereas intervention group intervened with Padlet. Data were analyzed with SPSS and revealed the intervention group has high Cohen effect (d) = .53, which is considered moderate size compared Cohen effect (d) = .17, considered small. This study clearly exhibits intervention group has better self-efficacy than control group. Further, the effect size of control group revealed decline in self-efficacy. In study exhibits there is no difference by gender in terms of self-efficacy. It is expected further study should be conducted by taking in to account sample size, duration of intervention, and method.

ABSTRACT Illicit substance use has been becoming the major global issue. In Indonesia, inmates imprisoned for illicit substance offences accounted for 40 percent of the total inmates. This study aimed to identify the effects of family psychoeducational therapies on inmates’ self esteem in the narcotics correctional facility.  Quasi-experimental pre-post test with control group was employed in this study. Intervention group 1 received general nursing intervention whereas intervention group 2 received family psychoeducational therapies.  This study involved 31 inmates for each group. Data were collected using Rosenberg Self Esteem Scale (RSES), and were analysed using repeated ANOVA dan independent t-tests. The study demonstrated that self esteem was significantly upper amongst those who received the combination of those two therapies compared to those who received general nursing intervention standalone (p < .005). This study suggested the implementation of both general nursing intervention and specialistic therapies, particularly family psychoeducational therapies to address the anxiety problems experienced by adolescent inmates suffering from illicit substance dependences.

Abstract Background Because of the antioxidant effects of Zataria multiflora (ZM) and carvacrol (CAR) and also the role of oxidative stress in the induction of cardiotoxicity induced by Adriamycin (ADR), the aim of this study was to investigate the improvement effects of ZM extract and CAR on cardiotoxicity induced by ADR in rats. Methods Twenty-eight male rats were randomly assigned to four groups including (1) the control group; (2) the ADR group, which received ADR intravenously at the beginning of the study and the (3) ZM+ADR and (4) CAR+ADR groups, which received ZM and CAR by gavage for 28 consecutive days and ADR as single dose. Blood samples were collected on days 0 and 28 to determine serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT) and lactate dehydrogenase (LDH). Also, cardiac tissue was removed for redox marker evaluation. Results In the ADR group, malondialdehyde (MDA) significantly increased and superoxide dismutase (SOD) activity and total thiol contents significantly reduced, as compared with the control group, while CAR administration significantly improved this condition. Treatment with ZM significantly increased the SOD activity and total thiol content, as compared with the ADR group. The level of LDH significantly increased on day 28 in the ADR group compared to the control group, and administration of ZM and CAR significantly decreased it. The SGPT and SGOT levels in the ADR group significantly increased, and CAR administration significantly reduced them. Conclusion The results indicate that the administration of ZM hydroalcoholic extracts and its active ingredient, CAR, could reduce the oxidative stress damage through promotion of the cardiac and systemic antioxidant system. Also, CAR administration demonstrated better improvement in cardiotoxicity with ADR in rats.

Abstract Objectives The objective of this study is to assess the effectiveness of a 6-month nutrition intervention to improve glycemic parameters and inflammation in prediabetic PLWH on stable ART with undetectable HIV viral load. Methods A 6-month randomized, controlled nutrition intervention was conducted in prediabetic PLWH. The study participants for the intervention were recruited from the Miami Adult Studies for HIV (MASH) cohort at the FIU-Borinquen Research Clinic. Upon their consent, the participants were randomized into the intervention group or the control group. Participants randomized in the intervention group met once a month for approximately 1 hour where they received medical nutrition therapy, nutrition counseling and nutrition education; participants randomized into the control group received educational material at baseline. Blood was drawn at baseline and at 6-month to measure fasting blood glucose (FBG) and high sensitivity C-reactive protein (hs-CRP). Results A total of 38 participants were recruited and randomized into either the intervention group (n = 20) or the control group (n = 18). We found that the FBG for the 6-month follow-up for the intervention group was significantly lower than the baseline FBG values of the same study group (paired t-test; P = 0.031). No significant difference was found in the control group between the baseline and 6-month fasting blood glucose values (P = 0.068). Moreover, no significant difference was found in pre/post C-reactive protein (CRP) levels in the intervention or control group (paired t-test; P = 0.404 and P = 0.117 respectively). There was a significant difference in CRP levels at baseline (P = 0.028) between the study groups but no difference at the 6-month follow up (Mann Whitney U test: P = 0.430). Conclusions The results from this intervention support the notion that a nutrition intervention is effective in prediabetic PLWH to lower diabetes risk by significantly lowering fasting blood glucose and may be implemented into larger scale interventions; however, no significant changes was seen in hs-CRP values between the 2 groups.

Disorders of the hemostatic system and inflammation play a key role in the pathogenesis of new coronavirus pneumonia (NCP), determining its course and outcome. To study the dynamics of the state of the hemostasis system and the severity of the acute phase response in patients with new coronavirus pneumonia. We determined APTT, prothrombin time (PT), fibrinogen (F), D-dimers (D-d), antitrombin III (AT III), C-reactive protein (CRP), platelet count in 22 patients. In 49 patients, the viscoelastic properties of a blood clot were studied by thromboelastography (TEG) with koalin. The age of the patients ranged from 40 to 77 years. According to CT, the severity of 100% cases corresponded to CT2-CT3. Acute respiratory failure (ARF) was diagnosed in 16 patients. A control group included 25 apparently healthy subjects. During hospitalization, patients with NCP were characterized by: an increase in the concentration of D-d, CRP, Fg, lengthening of APTT and PT, ATIII activity and platelet count not differing from the normal range. 10 days after hospitalization and against the background of ongoing therapy, patients with NCP showed positive dynamics in the hemostasiological profile and the severity of the inflammatory response. Thromboelastography indices in patients with LCP did not differ from control values both at hospitalization and on day 10.Thus, in patients with novel coronavirus pneumonia, an increased prothrombotic activity and a pronounced inflammatory response are recorded. Against the background of treatment, there is a positive dynamics in both the coagulation status and the inflammatory response. Additional studies are needed to determine the diagnostic capabilities of thromboelastography in patients with NCP.
