Abstract
Background HIV is one of the leading causes of morbidity and mortality, with 39.0 million people living with HIV worldwide, 25.6 million of whom reside in the African region. Highly active anti-retroviral therapy (HAART) has improved survival and quality of life, yet some patients develop viral non-suppression. Dolutegravir (DTG) has been recommended since 2018 as a first-line treatment option in low- and middle-income countries owing to its effectiveness, low cost, and tolerability, but some studies have reported virological non-suppression with its use. This study aims to explore the prevalence and factors associated with virological non-suppression in adults taking DTG-based regimens in Mbarara Regional Referral Hospital. Methods A retrospective cohort study was carried out among people living with HIV (PLWHIV) taking DTG-based HAART regimens by way of record review. SPSS was used for analysis, and both binary and multivariate logistic regression analyses were performed to test associated factors. Results Among the 422 participants' records reviewed, 62.8% were female (median age 40 years, IQR=13). The prevalence of virological non-suppression was 4.2%. Poor adherence to HAART was significantly associated with virological non-suppression, with 100.3 increased adjusted odds (95% CI: 28.90-348.12, p<0.001) compared to those with a record of good adherence. The reasons for poor adherence included alcohol use, stigma, forgetting to take medication, transport problems, and irregular timing of swallowing. Conclusion This study found poor adherence to be associated with a 4.2% prevalence of virological non-suppression among PLWHIV in a large public HIV care clinic. Despite the high suppression rates on DTG-based regimens, adherence counseling and viral load monitoring need to be emphasized at all HIV care centers to mark the trends of virological non-suppression.

Abstract
BACKGROUND To ensure the timely diagnosis of emerging infectious diseases, high-tech molecular biotechnology is often used to detect pathogens and has gradually become the gold standard for virological testing. However, beginners and students are often unable to practice their skills due to the higher costs associated with high-level virological testing, the increasing complexity of the equipment, and the limited number of specimens from patients. Therefore, a new training program is necessary to increase training and reduce the risk of test failure. OBJECTIVE The aim of the study is to (1) develop and implement a virtual reality (VR) software for simulated and interactive high-level virological testing that can be applied in clinical practice and skills building or training settings and (2) evaluate the VR simulation's effectiveness on reaction, learning, and behavior of the students (trainees). METHODS Viral nucleic acid tests on a BD MAX instrument were selected for our VR project because it is a high-tech automatic detection system. There was cooperation between teachers of medical technology and biomedical engineering. Medical technology teachers were responsible for designing the lesson plan, and the biomedical engineering personnel developed the VR software. We designed a novel VR teaching software to simulate cognitive learning via various procedure scenarios and interactive models. The VR software contains 2D VR "cognitive test and learning" lessons and 3D VR "practical skills training" lessons. We evaluated students' learning effectiveness pre- and posttraining and then recorded their behavior patterns when answering questions, performing repeated exercises, and engaging in clinical practice. RESULTS The results showed that the use of the VR software met participants' needs and enhanced their interest in learning. The average posttraining scores of participants exposed to 2D and 3D VR training were significantly higher than participants who were exposed solely to traditional demonstration teaching (P<.001). Behavioral assessments of students pre- and posttraining showed that students exposed to VR-based training to acquire relevant knowledge of advanced virological testing exhibited significantly improved knowledge of specific items posttraining (P<.01). A higher participant score led to fewer attempts when responding to each item in a matching task. Thus, VR can enhance students' understanding of difficult topics. CONCLUSIONS The VR program designed for this study can reduce the costs associated with virological testing training, thus, increasing their accessibility for students and beginners. It can also reduce the risk of viral infections particularly during disease outbreaks (eg, the COVID-19 pandemic) and also enhance students' learning motivation to strengthen their practical skills.

Abstract
BACKGROUND Pretreatment HIV drug resistance (PHDR) has emerged after scaling-up access to antiretroviral therapy (ART). This study aimed to compare long-term virological and immunological outcomes between HIV-positive individuals with and without PHDR. METHODS An observational cohort study was conducted in HIV-positive individuals who had a genotypic resistance test performed prior to ART initiation. RESULTS Of 335 participants, 39 were in the PHDR group and 296 were in the control group. ART regimen in PHDR group was adjusted at 6-10 weeks after ART initiation when results of baseline genotypic resistance test were available. Proportions of participants with undetectable viral load were significantly lower in PHDR group at 6 and 12 months (46.2% vs 79.4% (p < .001) and 74.4% vs 90.5% (p = .003), respectively). These virological responses became similar between two groups (p > .05) from 18 through 60 months. Mean change of CD4 counts of PHDR group was significantly lower only at 6 months (+59 vs + 81 cells/mm3 (p = .012); these immunological responses were similar between two groups from 12 through 60 months. CONCLUSION Early virological response was lower in HIV-positive participants with PHDR compared to participants without PHDR. Subsequent adjustment of ART according to pretreatment genotypic resistance has contributed to the long-term virological and immunological success that is similar to participants without PHDR.

Abstract
There are various diagnostic and research methods for detecting cases of Dengue fever, the effectiveness of which is given in this work. MATERIALS AND METHODS On biomaterial from 70 people, verification of imported cases of Dengue fever into the south of the Far East from 2012 to 2019 is shown. Serological and virological methods were used, as well as PCR. RESULTS Using the immunochromatographic rapid test, the Dengue virus (DENV) NS1 antigen and antibodies to DENV (IgM and IgG) were detected in human blood. We examined 12 patients from the infectious diseases department with unknown fever and the blood of 58 people who applied to clinics in Vladivostok after returning from tourist trips. Dengue fever was diagnosed in 23 patients (32.8%), of which antigen was detected in 56%, IgM antibodies in 91.3% and IgG in 52.1%. In 2 cases (8.7%), only antigen was detected in patients. Three strains of the pathogen were isolated by virological methods from 18 blood samples, two of which turned out to be the DENV of the 1st genotype and one - of the DENV of the 2nd genotype. Using RT-PCR, 38 blood samples were tested positive in the immunochromatographic rapid test, of which in 16 cases (42.1%) a DENV marker was detected, in 11 cases it was genotype 1, in three cases genotype 2, and one each - genotypes 3 and 4. CONCLUSIONS 1. The most reliable method of rapid verification (in 100%) the primary infection DENV was the comprehensive determination of antigen and antibodies of the IgM class; 2. With antigenemia, blood should be used to isolate the virus, as well as to diagnose the disease by PCR and to establish the genotype of the DENV; 3. When using only PCR to indicate Dengue virus, a significant proportion of the disease cases will not be diagnosed.

Abstract
Abstract
Background
Some people living with hepatitis C virus (HCV) with sustained virological response (SVR) develop hepatic complications. Liver stiffness (LS) predicts clinical outcome in people living with human immunodeficiency virus (HIV) with active HCV coinfection, but information after SVR is lacking. We aimed to analyze the predictive ability of LS at SVR for liver complications in people living with HIV/HCV with advanced fibrosis treated with direct-acting antivirals (DAA).
Methods
In sum, 640 people living with HIV/HCV fulfilling the following criteria were included: (i) Achieved SVR with DAA-including regimen; (ii) LS ≥ 9.5 kPa before therapy; and (iii) LS measurement available at SVR. The primary endpoint was the occurrence of a liver complication—hepatic decompensation or hepatocellular carcinoma (HCC)—or requiring liver transplant after SVR.
Results
During a median (Q1–Q3) follow-up of 31.6 (22.7–36.6) months, 19 (3%) patients reached the primary endpoint. In the multivariate analysis, variables (subhazard ratio [SHR] [95% confidence interval]) associated with developing clinical outcomes were: prior hepatic decompensations (3.42 [1.28–9.12]), pretreatment CPT class B or C (62.5 [3.08–1246.42]) and MELD scores (1.37 [1.03–1.82]), CPT class B or C at SVR (10.71 [1.32–87.01]), CD4 cell counts <200/µL at SVR time-point (4.42 [1.49–13.15]), FIB-4 index at SVR (1.39 [1.13–1.70]), and LS at SVR (1.05 [1.02–1.08] for 1 kPa increase). None of the 374 patients with LS <14kPa at SVR time-point developed a liver complication or required hepatic transplant.
Conclusions
LS at the time of SVR after DAA therapy predicts the clinical outcome of people living with HIV/HCV with advanced fibrosis. These results suggest that LS measurement may be helpful to select candidates to be withdrawn from surveillance programs.

Abstract
Background & Aims: Sofosbuvir is a powerful drug for the treatment of hepatitis C virus (HCV) infection. In comparison to preceding remedies, sofosbuvirbased regimens provide a higher cure rate, fewer side effects, and much lower duration of treatment. The aim of the work was to assess the efficacy and safety of sofosbuvir plus ribavirin with or without peginterferon-alfa in the treatment of a cohort of Egyptian patients with hepatitis C virus infection. METHODS Two hundred treatment naive patients who were HCV-antibody positive and HCV RNA by PCR positive aged more than 18 years were enrolled in the study and patients were classified into two groups: Group I which included 100 patients who received dual therapy with sofosbuvir plus oral weight based ribavirin for 24 weeks and Group II which included 100 patients on triple therapy with sofosbuvir plus oral weight based ribavirin (as with the dual therapy) and a 180 mcg Peg-INF alpha 2a subcutaneous injection weekly for 12 weeks. The primary end point was a sustained virological response at 12 weeks after end of the treatment determined by quantitative PCR for HCV. RESULTS Both patients groups had high sustained virological response that was higher in patients receiving triple than dual therapy (94% vs 83%). The adverse events that occurred in the two groups of patients were more evident in a group of patients receiving triple therapy. The side effects were mainly flu like symptoms. CONCLUSIONS The triple regimen of Pegylated interferon, sofosbuvir plus ribavirin is safe and effective in the treatment of Egyptian patients with hepatitis C virus as well as sofosbuvir and ribavirin alone wit.

Abstract
The aim of this study was to describe the obstetrical and virological outcomes in HIV-infected pregnant women who delivered at a district general hospital in south London in the period from 2008 to 2014. Our review identified 137 pregnancies; most (60%, 63/105) of them were unplanned. The commonest mode of delivery was spontaneous vaginal delivery (SVD) (42%, 48/114) followed by emergency Caesarean section (32%, 36/114). Gestational age at delivery was ≥37 weeks in most (84%, 91/106) of the cases. Maternal HIV VL at or closest to delivery was undetectable (<40 copies/mL), <400 copies/mL and >1000 copies/mL in 73% (94/129), 90% (116/129) and 6% (8/129) of the pregnancies, respectively. None of the infants were infected with HIV making the rate of MTCT of HIV 0% (zero). Our study shows that favourable virological and obstetrical outcomes of HIV-infected pregnant women are achievable in non-tertiary HIV treatment centres. Impact Statement What is already known on this subject: Prevention of mother-to-child transmission (MTCT) of HIV has been one of the major public health successes in the last decades. This success was evident by the reduction of MTCT of HIV in the UK from 25.6% in the 1993 to only 0.46% in 2011. Furthermore, many reports from individual providers, mainly from tertiary centres, of HIV care in the UK also showed very low rates MTCT of HIV. What the results of this study add: Our study shows that favourable virological and obstetrical outcomes of HIV-infected pregnant women are achievable in non-tertiary HIV treatment centres. The MTCT of HIV rate in our hospital was zero in the period from 2008 to 2014. What the implications are of these findings for clinical practice and/or further research: Staff caring for pregnant HIV positive women in general hospitals and small-to-medium HIV clinics should liaise closely with each other and utilise the skill-mix within their hospital in order to provide a quality care that is similar to what is achieved in large teaching centres; however, a prompt referral to tertiary hospitals, when indicated, should be facilitated.

Abstract
Despite immense progress in antiretroviral therapy (ART) scale-up, many people still lack access to basic standards of care, with our ability to meet the Joint United Nations Programme on HIV/AIDS 90-90-90 treatment targets for HIV/AIDS dependent on dramatic improvements in diagnostics. The World Health Organization recommends routine monitoring of ART effectiveness using viral load (VL) testing at 6 months and every 12 months, to monitor treatment adherence and minimize failure, and will publish its VL toolkit later this year. However, the cost and complexity of VL is preventing scale-up beyond developed countries and there is a lack of awareness among clinicians as to the long-term patient benefits and its role in prolonging the longevity of treatment programs. With developments in this diagnostic field rapidly evolving-including the recent improvements for accurately using dried blood spots and the imminent appearance to the market of point-of-care technologies offering decentralized diagnosis-we describe current barriers to VL testing in resource-limited settings. Effective scale-up can be achieved through health system and laboratory system strengthening and test price reductions, as well as tackling multiple programmatic and funding challenges.
