Time to develop adverse drug reactions and associated factors among children HIV positive patients on antiretroviral treatment in North West Amhara Specialized Hospitals: Retrospective cohort study, 2022.

Introduction: Adverse drug reactions (ADRs) are harmful and unintended reactions to medicines given at standard doses through a proper route of administration for the purpose of prophylaxis, diagnosis, or treatment. Objective: The objective of this research paper was to assess median time to development of ADRs and associated factors among children HIV positive patients on antiretroviral treatment (ART) in North West Amhara Specialized Hospitals. Methods: The adverse drug effect survival time was estimated using the Kaplan-Meier survival method and log-rank test curves was applied for analyze "time-to-event" data. Cox regression model was used to identify the associated factors. Adjusted hazard ratios with their respective 95% confidence intervals (CIs) were estimated and a value of p less than 0.05 was used to declare the presence of a significant association. Result: The overall incidence of ADRs was 0.67 (95% CI: 3.74-4.44) per 10,000 person-year observation, with a median of 57 months. Adults are presenting with opportunistic Infections (OIs) experiences, baseline CD4 < 200 cells/µL counts, 1e, tenofovir disoproxil fumarate-lamivudine-efavirenz ART regimen, bedridden baseline functional status, World Health Organization (WHO) clinical stage II and III were notably associated with the incidence of ADRs development. Conclusion: ADRs were uncommon in this study. predictors, such as OIs experiences, a low CD4 count, ART regimen, an advanced WHO stage, and bedridden functional status were significantly associated with ADRs.

Incidence of opportunistic infections and its predictors among HIV/AIDS patients on antiretroviral therapy in Gondar University Comprehensive and Specialized Hospital, Ethiopia.

Introduction: Opportunistic infections (OIs) are the leading cause of morbidity and mortality among adults living with HIV. Current and accurate information about the occurrence of opportunistic infections in HIV-infected adults is critical for developing more effective treatments and interventions. However, few studies have been conducted in Ethiopia on the prevalence of common opportunistic infections in HIV-infected adults. Thus, the purpose of this study was to determine the prevalence and predictors of opportunistic infections among HIV-infected adults receiving antiretroviral therapy (ART) at the comprehensive specialized hospital affiliated with the University of Gondar.Methods: Between January 11, 2015, and January 10, 2021, a retrospective cohort study was conducted at the University of Gondar comprehensive specialized hospital. A total of 715 HIV-infected adults on ART were included in the study. Data were extracted from the charts of HIV-infected adults using a data extraction form adapted from the ART entry and follow-up forms. Epi-dataTM Version 4.5 was used to enter data, and StataTM Version 16 was used to analyze the data. The time interval between opportunistic infections was estimated using the Kaplan Meier survival curve. To identify risk predictors of opportunistic infections, bivariate and multivariate semi-parametric and parametric regression models were fitted.Result: This study included the records of 715 HIV-infected adults-initiated ART between January 11, 2015, to January 10, 2021. During the follow-up period, the overall incidence of opportunistic infections was 4.1 (95 percent CI 3.74 to 4.44) per 10,000 person-year observation, with a median of 57 months (IQR = 40-69 months). Pneumocystis' pneumonia at 90(16.51%) was the most encountered OI at follow-up. Adults are presenting with baseline CD4 < 200 cells/µl counts (AHR = 1.41, 95% CI 1.18 to 1.69), bedridden baseline functional status (AHR = 1.35, 95% CI 1.01 to 1.82), WHO clinical stage II (AHR = 5.87, 95% CI 3.97 to 8.69) and WHO clinical stage III (AHR = 5.85, 95% CI 3.55 to 9.65) were notably associated with the incidence of opportunistic infections development.Conclusions: Opportunistic infections are uncommon among HIV-infected adults in this study. In terms of predictors, such as a low CD4 count and an advanced WHO stage (II or III), bedridden functional status was found to be significantly associated with OIs.

Factors Associated with Pre- and Post-Educational Intervention Knowledge Levels of HPV and Cervical Cancer Among the Male and Female University Students, Northwest Ethiopia.

BACKGROUND: Human papillomavirus (HPV) infections are sexually transmitted and most frequently associated with cervical cancer in women, but they are also a public health concern in men. There is rising evidence that HPV's role in other cancers, such as anal, vulva, vaginal, penis, head, and neck cancers. The present study aimed to understand the factors associated with HPV and cervical cancer knowledge levels of university students before and after an educational intervention. METHODS: An Institutional-based cross-sectional study was conducted from October to November 2018. A total of 638 study participants were selected using a simple random multistage sampling technique. A pretested questionnaire was used, consolidated the data, and analyzed with SPSS version 23. Bivariate and multivariate logistic regression analyses were performed to identify which variables were associated with the knowledge levels. RESULTS: Six hundred thirty-eight study participants with a 100% response rate, and the mean age was 21.07 years (±SD, 1.96). Initial awareness of various broad categories was 4.09, and after the intervention, it increased to 23.4, with an average increase of 19.31 at 99% CI, p≤0.001 significance level. Before the educational intervention, students with <21 years of age [6.16, 95% CI: (2.21-17.18)] and ≤2.5 CGPA [3.44, 95% CI: (1.51-7.81)] were less knowledgeable over other counterparts. After educational intervention, the year of study was significantly associated with increased knowledge of overall and different broad categories of cervical cancer and HPV. Year of study, 1st-year students [AOR: 0.27, 95% CI: (0.14-0.51)] over third years and above are less knowledgeable. First-year students and CGPA ≤2.5 were less improved awareness over others. CONCLUSION: The educational intervention improved more than fourfold increase knowledge on cervical cancer and HPV, and the year of study was a key factor associated with overall improvement. This study suggests that educational intervention effectively strengthens our understanding of the spread of HPV and cervical cancer disease burden.

Screening and Characterization of Thermostable Amylase-Producing Bacteria Isolated from Soil Samples of Afdera, Afar Region, and Molecular Detection of Amylase-Coding Gene.

Studying thermostable amylase-producing bacteria in extreme environments has a crucial role to overcome different industrial challenges. Afar Region is one of the hottest and salty areas, making it the home of extremophiles. This study aimed at screening and characterizing amylase-producing bacteria isolated from soil samples of Afdera, Afar Region, and detection of their amylase-coding genes. Thus, a total of 49 bacterial isolates were obtained from the collected soil samples. Out of these, three isolates (M2, M8, and M13) were selected on the basis of diameter of the average clear zone formation and time taken to decolorize iodine solution. Based on their morphological and biochemical characteristics, the isolates were identified as genus Bacillus. PCR amplification and detection of the amylase-coding gene confirmed the presence of the amylase gene in the three bacterial isolates. Optimum amylase production time for these isolates was 48 hrs (M13 and M8) and 72 hrs (M2) corresponding to the amylase activity of 0.67 U/mL for M13, 0.74 U/mL for M8, and 0.73 U/mL for M2 with an optimum temperature of 55°C. Studies on the effect of temperature revealed that the crude enzyme had a maximum activity and stability at 75°C, 70°C, and 65°C for isolates M13, M8, and M2, respectively. Additionally, amylase produced from all isolates retained more than 66.41% of their original activity after incubating them at a temperature range from 55 to 80°C for 50 min. Optimum pH for the activity of all crude amylases was in the range from 5 to 9 with a peak activity at pH 8. Their activity decreased significantly by the presence of Zn+2 and Mg2+; however, their activity increased by the presence of Ca+2. Moreover, the three crude amylases were stable (0-3 M) with NaCl concentration. Amylases of this finding with thermophilic and halophilic characteristics offer a wide range of applications in food, brewing, textile, starch, paper, and deterrent industries. Thus, identification of these Bacillus isolates at a molecular level and purification as well as detailed characterization of the types of amylases are recommended for effective utilization in different industries.

The Role of Pi, Glutamine and the Essential Amino Acids in Modulating the Metabolism in Diabetes and Cancer.

PURPOSE: Re-examine the current metabolic models. METHODS: Review of literature and gene networks. RESULTS: Insulin activates Pi uptake, glutamine metabolism to stabilise lipid membranes. Tissue turnover maintains the metabolic health. Current model of intermediary metabolism (IM) suggests glucose is the source of energy, and anaplerotic entry of fatty acids and amino acids into mitochondria increases the oxidative capacity of the TCA cycle to produce the energy (ATP). The reduced cofactors, NADH and FADH2, have different roles in regulating the oxidation of nutrients, membrane potentials and biosynthesis. Trans-hydrogenation of NADH to NADPH activates the biosynthesis. FADH2 sustains the membrane potential during the cell transformations. Glycolytic enzymes assume the non-canonical moonlighting functions, enter the nucleus to remodel the genetic programmes to affect the tissue turnover for efficient use of nutrients. Glycosylation of the CD98 (4F2HC) stabilises the nutrient transporters and regulates the entry of cysteine, glutamine and BCAA into the cells. A reciprocal relationship between the leucine and glutamine entry into cells regulates the cholesterol and fatty acid synthesis and homeostasis in cells. Insulin promotes the Pi transport from the blood to tissues, activates the mitochondrial respiratory activity, and glutamine metabolism, which activates the synthesis of cholesterol and the de novo fatty acids for reorganising and stabilising the lipid membranes for nutrient transport and signal transduction in response to fluctuations in the microenvironmental cues. Fatty acids provide the lipid metabolites, activate the second messengers and protein kinases. Insulin resistance suppresses the lipid raft formation and the mitotic slippage activates the fibrosis and slow death pathways.
