Various biochemical tests exist for its diagnosis, but low sensitivity and cross-reactivity led the focus toward improved serological methods: immunoglobulin-based and enzyme immunodetection. This study aims to determine the effectiveness of improved enzyme immunodetection methods in hepatitis E virus laboratory diagnosis compared with other diagnostic methods. A systematic literature review was conducted over secondary source databases: Google Scholar, Web of Science, Springer, ScienceDirect, and PubMed. The study followed a Preferred Reporting of Items for Systematic Reviews and Meta-Analysis checklist for conducting the systematic review. Abstracted and fulltext peer-reviewed articles were selected, published in English in 2015-2022. The study employed keywords and set publication dates to search for the most relevant articles. However, these studies were assessed using the risk of bias tools: the Cochrane Risk of Bias for randomized controlled design and the Newcastle-Ottawa Scale for non-randomized controlled design. Critical Appraisal Skills Programme checklist was also used to assess the quality of the studies that cannot be assessed by the Cochrane risk of bias tool and Newcastle-Ottawa Scale. After the selection, the data were synthesized using a qualitative approach to present the results. About 10 articles were identified, including randomized, cohort, qualitative, and diagnostic studies. They found the specificity of an immunoassay to achieve a significantly high specificity (98.3%) and sensitivity (89.5%) for immunoglobulin G-based hepatitis E virus detection. However, they reported that immunoglobulin G and immunoglobulin M detection in the suspected hepatitis E virus patients and exposed groups gave potential results for detecting hepatitis E virus. The method was found as efficient as can be designed as non-invasive and with low risks and challenges. The results showed that the improved enzyme immune-detective method can assist in providing a reliable, easily accessible, and error-free hepatitis E virus diagnostic method. Thus, future research must focus on exploiting these methods and strategies.","PeriodicalId":353660,"journal":{"name":"THE NEW ARMENIAN MEDICAL JOURNAL","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139339427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While several factors have been proposed to contribute to its occurrence, the link between caffeine consumption, anxiety levels, and the development of aphthous stomatitis remains unknown. This survey-based study aimed to understand the association between coffee, anxiety, and the development of aphthous stomatitis in this specific demographic, which can provide useful insights for medical management as well as preventive strategies. Material and methods: A structured online questionnaire was distributed via various social media platforms targeting a sample of the Armenian population. The questionnaire collected information on participants’ demographics, coffee use patterns, anxiety levels as measured by perceived stress scales, and the occurrence of aphthous stomatitis. Statistical analyses, including Kendall’s tau, were carried out to investigate the relationships. Results: The results revealed a significant negative association between caffeine consumption and the occurrence of aphthous stomatitis among Armenian individuals Kendall’s tau-b (τb) correlation - 240* (p<0.05). Participants who reported regular caffeine consumption, such as coffee, tea, and energy drinks, had a lesser prevalence of aphthous stomatitis than non-consumers. Furthermore, Armenians in the survey showed that the majority (83.5%) had a low to moderate stress level. Conclusion: The data we collected in our research indicate that the prevalence of Recurrent Aphthous Stomatitis in the Armenian ethnicity was infrequent; over half of the participants didn’t report Recurrent Aphthous Stomatitis in the past 12 months. Which may correlate to their caffeine consumption habits, which can lead to stress reduction.","PeriodicalId":353660,"journal":{"name":"THE NEW ARMENIAN MEDICAL JOURNAL","volume":"65 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139341829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients with either clinical or echocardiographic findings of congenital heart disease were referred for complementary evaluation with computed tomography angiography. Results: Finally, 203 patients were included in this study. The prevalence of an aberrant right subclavian artery was presented in 24 patients (11.8%). Moreover, the most common aortic arch anomaly was coarctation 40 (19.7%). The only double outlet right ventricle cardiac abnormality was associated with a higher risk of an aberrant right subclavian artery (relative risk, 1.192; 95% CI, 0.179 – 7.95) relative to other aortic arch anomalies. Discussion: In conclusion, this study showed that the incidence of aberrant right subclavian artery in an extensive series of Aortic Arch Anomalies had been performed (11.8%). Furthermore, pulmonary atresia, total anomalous pulmonary venous return, aortic coarctation, cervical arch, aortic interruption, tubular hypoplasia, and pulmonary sling were significantly higher in the aberrant right subclavian artery group in contrast with Other Aortic Arch Anomalies.

We chose phytoestrogens as an alternate treatment for atrophic vaginitis because of the potentially substantial side effects of long-term hormone replacement therapy use documented in a large prospective trial. Materials and methods: In this research, Flax Seed, Foeniculum Vulgare, and Salvia officinalis were chosen as plants containing phytoestrogen. Three vaginal cream formulations (F1-F3) were prepared in this study. The physicochemical properties and stability of a vaginal lotion containing well-known phytoestrogen plants are investigated. This study evaluates Linum usitatissimum, Foeniculum vulgare seeds, and Salvia officinalis extract. Physical examination, stability, continuity, active ingredient release, and challenge test were the four key criteria for product evaluation. Results: The release test revealed that extracts from formulation 2 and formulation 3 were slower to release than formulation1. It is owing to F1’s decreased viscosity and F2 and F3’s higher hydrophilic properties. The polyethylene glycol in formulations F2 and F3 may increase the hydrophilicity of the formulation, resulting in a stronger inclination of hydrophilic flavonoid extracts to the base and a decrease in extract liberation from the formulation. The w/o nature of the formulations allows them to lubricate or moisturize the vaginal epithelium, reducing Atrophic vaginitis symptoms. Conclusion: Formulation 1 may be a viable alternative to the current treatments for atrophic vaginitis. To determine the efficacy of this herbal vaginal cream in treating the symptoms of atrophic vaginitis, however, additional scientific studies are necessary.","PeriodicalId":353660,"journal":{"name":"THE NEW ARMENIAN MEDICAL JOURNAL","volume":"49 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139350030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In malignantly transformed cells, a high level of aliphatic polyamines has been observed, which ensures their steady anaplastic growth. This is precisely why elevated levels of the aforementioned polyamines are considered as diagnostic and prognostic criteria for a wide range of oncological diseases. In several developed countries, cancer patients are advised to follow a low-polyamine diet, including specifically those food products that are identified in the general nutrient registry as having low levels of aliphatic polyamines. However, when recommending such a diet, many researchers did not pay attention to the fact that in different food products, the ratio of polyamine levels often varies within very wide limits. Therefore, as some researchers report a polyamine-deficient diet prescribed to cancer patients is not always effective. We analyzed various literary sources and identified products that do not contain polyamines or contain them in very low quantities. Based on the analysis of available literary data, when patients are admitted to oncology clinics, along with generally accepted laboratory diagnostic criteria, it is necessary to include diagnostic indicators for determining the levels of aliphatic polyamines in erythrocytes and blood plasma, including putrescine, spermidine, spermine, and cadaverine. Due to this approach, oncologists and nutritionists may have a real opportunity to prescribe a selective polyamine-deficient diet. For patients with advanced cancer, we recommend the use of a polyamine-free diet instead of a polyamine-deficient one.","PeriodicalId":353660,"journal":{"name":"THE NEW ARMENIAN MEDICAL JOURNAL","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139351131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this work was the investigation of nitric oxide inhalations action on some parameters of energy and oxidative metabolism of healthy rat blood. Wistar rats were randomly divided into two groups: control group (without any manipulations; n=10) and main group (n=10) with inhalations by nitric oxide-containing gas flow (20 ppm). Lactate dehydrogenase and lactate level were estimated in rat blood samples. In addition, we calculated a number of integral coefficients of energy metabolism, such as substrate provision coefficient and coefficient of energy reactions balance. Our experiments demonstrate that 10-days course of inhalations of low nitric oxide doses (20 ppm) increases the adaptive potential of healthy rats’ organism. One of these positive effects is associated with activation of some components of energy metabolism. First of all, it realized through stimulation of catalytic activity of lactate dehydrogenase, including its erythrocyte pool.
