Abstract The glutathione-S-transferase (GST) enzymes are phase II isoenzymes responsible for protection against free radicals and xenobiotics. Since these proteins are described as polymorphic, polymorphisms in genes that encode them may alter enzymatic function and contribute to oxidative stress. In this context, such polymorphisms were already associated with several diseases and multiple therapeutic outcomes. A systematic review was performed to evaluate studies regarding the association between polymorphisms in three genes encoding enzymes of the GST family – GSTM1, GSTT1, and GSTP1 – and disorders in transplant patients. A total of 125 articles on which inclusion and exclusion criteria were applied were identified at PubMed database. Thirty-two studies met the target criteria and were included in the review. The mechanisms by which GST genotypes influence the development of disorders in transplant patients differ by disorder: they may participate in it by decreasing metabolism of drugs administered to patients undergoing transplantation, then exposing them to greater toxicity; by decreasing the repair ability against oxidative stress; or by encoding proteins that may be recognized as foreign, setting of an alloimmune reaction. Although some results are better established – such as GSTM1 null genotype’s role in the development of toxicity events in transplant patients – others require further evidences, as GST influence on the development of pulmonary decline and posttransplant diabetes mellitus (PTDM). The importance of investigating these associations lies in a personalized medicine, in which the high-risk genotype patient has its treatment individualized and its care for prophylaxis and surveillance increased, potentially reducing this population’s morbimortality.

The Relationship

Was to conduct a systematic review of data on the relationship between polymorphisms genes of detoxification system and development of preeclampsia (РЕ). Рresents the main genes of detoxification system (GSTPI, GSTМI, GSTТI, GРХI, ЕРНХI, SOD-2, SOD-3, CYPIAL, MTHЕR, MTR) and their functions. Of interest is the possibility of calculating the individual risk of PE based on the results about the presence of a combination of different polymorphisms in the genotype of the female. Question about early diagnosis of РЕ remains controversial and not fully understood. It is necessary to conduct further in-depth, extended study of this problem. Key words: preeclampsia, oxidative stress, genes of the detoxification system.

Background: Socioeconomic and demographic statuses are associated with adherence to the treatment of patients with several chronic diseases. However, there is a controversy regarding their impact on adherence among HIV/AIDS patients. Thus, we performed a systematic review of the evidence regarding the association of socioeconomic and demographic statuses with adherence to antiretroviral therapy (ART) among HIV/AIDS patients. Methods: The PubMed database was used to search and identify studies concerning about socioeconomic and demographic statuses and HIV/AIDS patients. Data were collected on the association between adherence to ART and varies determinants factors of socioeconomic (income, education, and employment/occupation) and socio-demographic (sex and age). Findings: From 393 potentially-relevant articles initially identified, 35 original studies were reviewed in detail, which contained data that were helpful in evaluating the association between socioeconomic/ demographic statuses and adherence to ART among HIV patients. Two original research study has specifically focused on the possible association between socioeconomic status and adherence to ART. Income, level of education, and employment/occupational status were significantly and positively associated with the level of adherence in 7 studies (36.8%), 7 studies (28.0%), and 4 studies (23.5%) respectively out of 19, 25, and 17 studies reviewed. Sex (being male), and age (per year increasing) were significantly and positively associated with the level of adherence in 5 studies (14.3%), and 9 studies (25.7%) respectively out of 35 studies reviewed. However, the determinant of socioeconomic and demographic statuses was not found to be significantly associated with adherence in studies related to income 9(47.4%), education 17(68.0%), employment/ occupational 10(58.8%), sex 27(77.1%), and age 25(71.4%). Conclusion: The majority of the reviewed studies reported that there is no association between socio- demographic and economic variables and adherence to therapy. Whereas, some studies show that age of HIV patients (per year increasing) and sex (being male) were positively associated with adherence to ART. Among socio-economic factors, the available evidence does not provide conclusive support for the existence of a clear association with adherence to ART among HIV patients. There seems to be a positive trend between socioeconomic factors and adherence to ART in some of the reviewed studies.

Objective: This study aimed to detect hepatic oxidative damage caused by aflatoxin B1 (AFB1), as well as to examine how propolis protects against hepatotoxic effects of AFB1. Method: Rats were split into four groups as control group, AFB1 group, propolis group, AFB1+ propolis group. Results: There was significant increase in malondialdehyde (MDA) level and tumor suppressor protein (TP53) gene expression, Glutathione (GSH) level, Catalase (CAT) activity, CAT gene expression decreased in AFB1 group in blood. MDA level and Glutathione-S-Transferase (GST) activity, GST and TP53 gene expressions increased in AFB1 group, whereas GSH level and CAT activity alongside CAT gene expression decreased in liver. AFB1+propolis group showed significant decrease in MDA level, GST activity, TP53 and GST gene expressions, GSH level and CAT activity and CAT gene expression increased in liver compared to AFB1 group. Conclusion: These results suggest that propolis may potentially be natural agent that prevents AFB1- induced oxidative stress and hepatotoxicity.

Introduction: Over 4.9 million cases of Coronavirus disease 2019 (COVID-19) have been confirmed since the worldwide pandemic began. Since the emergence of COVID-19, a number of confirmed cases reported autoimmune manifestations. Herein, we reviewed the reported COVID-19 cases with associated autoimmune manifestations. Methods: We searched PubMed database using all available keyword for COVID-19. All related studies between January 1st, 2020 to May 22nd, 2020 were reviewed. Only studies published in English language were considered. Articles were screened based on titles and abstract. All reports of confirmed COVID-19 patients who have associated clinical evidence of autoimmune disease were selected. Results: Among 10006 articles, searches yielded, Thirty-two relevant articles for full-text assessment. Twenty studies meet the eligibility criteria. The twenty eligible articles reported 33 cases of confirmed COVID-19 diagnosis who developed an autoimmune disease after the onset of covid-19 symptoms. Ages of patients varied from a 6 months old infant to 89 years old female (Mean=53.9 years of 28 cases); five cases had no information regarding their age. The time between symptoms of viral illness and onset of autoimmune symptoms ranged from 2 days to 33 days (Mean of the 33 cases=9.8 days). Autoimmune diseases were one case of subacute thyroiditis (3%), two cases of Kawasaki Disease (6.1%), three cases of coagulopathy and antiphospholipid syndrome (9.1%), three cases of immune thrombocytopenic purpura (9.1%), eight cases of autoimmune hemolytic anemia (24.2%), and sixteen cases of Guillain–Barré syndrome (48.5%). Conclusions: COVID-19 has been implicated in the development in a range of autoimmune diseases which may shed a light on the association between autoimmune diseases and infections.

Abstract Background Over the last years, laparoscopic appendectomy has progressively replaced open appendectomy and become the current gold standard treatment for suspected, uncomplicated appendicitis. At the same time, though, it is an ongoing discussion that antibiotic therapy can be an equivalent treatment for patients with uncomplicated appendicitis. The aim of this systematic review was to determine the safety and efficacy of antibiotic therapy and compare it to the laparoscopic appendectomy for acute, uncomplicated appendicitis. Methods The PubMed database, Embase database, and Cochrane library were scanned for studies comparing laparoscopic appendectomy with antibiotic treatment. Two independent reviewers performed the study selection and data extraction. The primary endpoint was defined as successful treatment of appendicitis. Secondary endpoints were pain intensity, duration of hospitalization, absence from work, and incidence of complications. Results No studies were found that exclusively compared laparoscopic appendectomy with antibiotic treatment for acute, uncomplicated appendicitis. Conclusions To date, there are no studies comparing antibiotic treatment to laparoscopic appendectomy for patients with acute uncomplicated appendicitis, thus emphasizing the lack of evidence and need for further investigation.

Auditory Verbal Therapy

This systematic review sheds light on the effectiveness of auditory–verbal therapy (AVT) outcomes in children with cochlear implants (CIs). The presented outcome is based on research findings from the last 10 years. The systematic review was designed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and Critical Appraisal of Treatment Evidence (CATE) checklist. Specific keywords were chosen based on the research question and searched on the PubMed database. All searched papers were analysed based on specific exclusion criteria and classified into four evidence levels. The results revealed that children who participated in AV therapy can achieve linguistic skills at the same level as their hearing peers. Voice quality seemed positively affected, placing young children with CIs in the normal range for receptive vocabulary development. In contrast, reading skills seemed less benefited. AV therapy seems to contribute to integration into mainstream society. Despite the recorded speech and language improvements of young children with CIs, the aim of AV therapy is still not fulfilled. AV therapy can be seen as the best clinical practice for young children with CIs till now, but the lack of well-controlled studies is undermining.
