Abstract
A significant portion of human cancers are caused by oncoviruses (12%-25%). Oncoviruses employ various strategies to promote their replication and induce tumourigenesis in host cells, one of which involves modifying the gene expression patterns of the host cells, leading to the rewiring of genes and resulting in significant changes in cellular processes and signalling pathways. In recent studies, a specific mode of gene regulation known as circular RNA (circRNA)-mediated competing endogenous RNA (ceRNA) networks has emerged as a key player in this context. CircRNAs, a class of non-coding RNA molecules, can interact with other RNA molecules, such as mRNAs and microRNAs (miRNAs), through a process known as ceRNA crosstalk. This interaction occurs when circRNAs, acting as sponges, sequester miRNAs, thereby preventing them from binding to their target mRNAs and modulating their expression. By rewiring the host cell genome, oncoviruses have the ability to manipulate the expression and activity of circRNAs, thereby influencing the ceRNA networks that can profoundly impact cellular processes such as cell proliferation, differentiation, apoptosis, and immune responses. This review focuses on a comprehensive evaluation of the latest findings on the involvement of virus-induced reprogramming of host circRNA-mediated ceRNA networks in the development and pathophysiology of human viral cancers, including cervical cancer, gastric cancer, nasopharyngeal carcinoma, Kaposi's sarcoma, hepatocellular carcinoma, and diffuse large B cell lymphoma. Understanding these mechanisms can improve our knowledge of how oncoviruses contribute to human tumourigenesis and identify potential targets for developing optimised therapies and diagnostic tools for viral cancers.

Abstract
INTRODUCTION To end the HIV epidemic in Philadelphia, implementation of evidence-based practices (EBP) to increase viral suppression and retention in HIV care is critical. Managed problem solving (MAPS), an EBP for antiretroviral therapy adherence, follows a problem-solving approach to empower people living with HIV (PWH) to manage their health. To overcome barriers to care experienced by PWH in Philadelphia, the EBP was adapted to include a focus on care retention and delivery by community health workers (CHWs). The adapted intervention is MAPS+. To maximise the clinical impact and reach of the intervention, evaluation of the effectiveness and implementation of MAPS+ is necessary. METHODS AND ANALYSIS This manuscript describes the protocol for a stepped-wedge cluster-randomised type 2 hybrid effectiveness-implementation trial in 10 clinics in Philadelphia. This research incorporates innovative approaches to accomplish three objectives: (1) to evaluate the effectiveness of the CHW-led MAPS+ intervention to improve viral suppression and retention in care 1 year after the individual implementation period (N=390 participants), (2) to examine the effect of the menu of implementation strategies on reach and implementation cost and (3) to examine processes, mechanisms, and sustainment of the implementation strategies for MAPS+ (N=56 participants). Due to various factors (eg, COVID-19), protocol modifications have occurred. ETHICS AND DISSEMINATION The institutional review board (IRB) at the city of Philadelphia serves as the primary IRB; initial approval was granted on 21 December 2020. The University of Pennsylvania and Northwestern University executed reliance agreements. A safety monitoring committee comprised experts in implementation science, biostatistics and infectious diseases oversee this study. This research will offer insights into achieving the goals to end the HIV epidemic in Philadelphia as well as implementation efforts of MAPS+ and other behavioural interventions aimed at increasing medication adherence and retention in care. Dissemination will include deliverables (eg, peer-reviewed manuscripts and lay publications) to reach multiple constituents. TRIAL REGISTRATION NUMBER NCT04560621.

Abstract
Despite evidence supporting HIV pre-exposure prophylaxis (PrEP) effectiveness, very few women with opioid use disorder (OUD) take PrEP. Interventions that improve medication assisted treatment (MAT) uptake and adherence may also be beneficial for PrEP. The reSET-O mobile phone app is a component of the evidence-based Therapeutic Education System, which improves retention and abstinence for people with OUD. To better understand use of this mobile health tool as a support for PrEP among women with OUD, pre-implementation contextual inquiry is needed. Therefore, we set out to assess target user characteristics, implementation barriers, feasibility, and acceptability of reSET-O. We recruited women with OUD receiving care from a community-based organization in Philadelphia to complete semi-structured interviews. All participants were prescribed reSET-O. We interviewed 20 participants (average age 37 years; 70% white, 15% Hispanic, 5% Black) from 5/2021 to 2/2022. We used an integrated analysis approach combining modified grounded theory and implementation science constructs. Half reported recent injection drug use, and 6 were taking buprenorphine. Mental health symptoms were common, and half described engaging in transactional sex. The majority expressed strong interest in PrEP. Participants reported the app would be highly acceptable for PrEP and MAT adherence support, but only two redeemed the prescription. The most common barriers included phone and internet access. Our findings highlight potential implementation challenges for the use of such an app to support PrEP use in this population. Poor uptake of the app at follow-up indicates that initial prescription redemption is a major barrier to reSET-O implementation.

Abstract
Burn is one of the physically debilitating injuries that can be potentially fatal; therefore, providing appropriate coverage in order to reduce possible mortality risk and accelerate wound healing is mandatory. In this study, collagen/exo-polysaccharide (Col/EPS 1-3%) scaffolds are synthesized from rainbow trout (Oncorhynchus mykiss) skins incorporated with Rhodotorula mucilaginosa sp. GUMS16, respectively, for promoting Grade 3 burn wound healing. Physicochemical characterizations and, consequently, biological properties of the Col/EPS scaffolds are tested. The results show that the presence of EPS does not affect the minimum porosity dimensions, while raising the EPS amount significantly reduces the maximum porosity dimensions. Thermogravimetric analysis (TGA), FTIR, and tensile property results confirm the successful incorporation of the EPS into Col scaffolds. Furthermore,the biological results show that the increasing EPS does not affect Col biodegradability and cell viability, and the use of Col/EPS 1% on rat models displays a faster healing rate. Finally, histopathological examination reveals that the Col/EPS 1% treatment accelerates wound healing, through greater re-epithelialization and dermal remodeling, more abundant fibroblast cells and Col accumulation. These findings suggest that Col/EPS 1% promotes dermal wound healing via antioxidant and anti-inflammatory activities, which can be a potential medical process in the treatment of burn wounds.

Abstract
Abstract
Background
Pre-exposure prophylaxis (PrEP) is an evidence-based intervention shown to effectively reduce HIV infection. However, PrEP is under-utilized, especially among racial and ethnic minority groups where HIV incidence is the highest. Here, we aim to describe the impact of structural racism and discrimination (SRD) on the PrEP continuum.
Methods
We performed a systematic review of the published literature using MEDLINE database for keywords such as HIV, PrEP, racism, and healthcare disparities. Inclusion criteria were original, U.S.-based studies in English published since 2012. Our main exposure was SRD defined as a socially structured action that is unfair and harms individuals and groups on the basis of race, ethnicity and/or other statuses. Outcome measures included ≥ 1 step of the PrEP continuum. Qualitative analyses were excluded.
Results
The search returned 297 papers, from which 37 studies met inclusion criteria. SRD was described at the individual level in 1 studies, at the interpersonal in 17 studies, and the societal level in 15 studies with some studies including multiple levels of SRD. In 4 studies, there were no reported differences by race and 1 study reported no differences by neighborhood socioeconomic status. Disparities were observed across each step of the PrEP continuum with Black and Hispanic patients being less likely to have a discussion about PrEP, less likely to receive a PrEP prescription and less likely to adhere or be retained in PrEP care compared to White patients. In two large studies, race-based differences in PrEP prescription were particularly stark: one study with 25,886 patients reported that Black race was found to be an independent factor for non-PrEP prescription and the other with 32,853 patients found that PrEP prescription was 6 times higher among Whites compared to Black patients. Potential mediators to poor PrEP continuum outcomes included perceived healthcare-related discrimination, provider related implicit bias and racial stereotypes, housing instability, food insecurity, insurance status, and history of incarceration.
Conclusion
SRD at multiple levels contribute to racial disparities across the PrEP continuum. Strategies that reduce SRD may help to mitigate racial/ethnic disparities in PrEP continuum outcomes.

Abstract
IMPORTANCE Significant differences in hesitancy to receive COVID-19 vaccination by race/ethnicity have been observed in several settings. Racial/ethnic differences in COVID-19 vaccine hesitancy among health care workers (HCWs), who face occupational and community exposure to COVID-19, have not been well described. OBJECTIVE To assess hesitancy to COVID-19 vaccination among HCWs across different racial/ethnic groups and assess factors associated with vaccine hesitancy. DESIGN, SETTING, AND PARTICIPANTS This survey study was conducted among HCWs from 2 large academic hospitals (ie, a children's hospital and an adult hospital) over a 3-week period in November and December 2020. Eligible participants were HCWs with and without direct patient contact. A 3-step hierarchical multivariable logistic regression was used to evaluate associations between race/ethnicity and vaccine hesitancy controlling for demographic characteristics, employment characteristics, COVID-19 exposure risk, and being up to date with routine vaccinations. Data were analyzed from February through March 2021. MAIN OUTCOMES AND MEASURES Vaccine hesitancy, defined as not planning on, being unsure about, or planning to delay vaccination, served as the outcome. RESULTS Among 34 865 HCWs eligible for this study, 12 034 individuals (34.5%) completed the survey and 10 871 individuals (32.2%) completed the survey and reported their race/ethnicity. Among 10 866 of these HCWs with data on sex, 8362 individuals (76.9%) were women, and among 10 833 HCWs with age data, 5923 individuals (54.5%) were younger than age 40 years. (Percentages for demographic and clinical characteristics are among the number of respondents for each type of question.) There were 8388 White individuals (77.2%), 882 Black individuals (8.1%), 845 Asian individuals (7.8%), and 449 individuals with other or mixed race/ethnicity (4.1%), and there were 307 Hispanic or Latino individuals (2.8%). Vaccine hesitancy was highest among Black HCWs (732 individuals [83.0%]) and Hispanic or Latino HCWs (195 individuals [63.5%]) (P < .001). Among 5440 HCWs with vaccine hesitancy, reasons given for hesitancy included concerns about side effects (4737 individuals [87.1%]), newness of the vaccine (4306 individuals [79.2%]), and lack of vaccine knowledge (4091 individuals [75.2%]). The adjusted odds ratio (aOR) for vaccine hesitancy was 4.98 (95% CI, 4.11-6.03) among Black HCWs, 2.10 (95% CI, 1.63-2.70) among Hispanic or Latino HCWs, 1.48 (95% CI, 1.21-1.82) among HCWs with other or mixed race/ethnicity, and 1.47 (95% CI, 1.26-1.71) among Asian HCWs compared with White HCWs (P < .001). The aOR was decreased among Black HCWs when adjusting for employment characteristics and COVID-19 exposure risk (aOR, 4.87; 95% CI, 3.96-6.00; P < .001) and being up to date with prior vaccines (aOR, 4.48; 95% CI, 3.62-5.53; P < .001) but not among HCWs with other racial/ethnic backgrounds. CONCLUSIONS AND RELEVANCE This study found that vaccine hesitancy before the authorization of the COVID-19 vaccine was increased among Black, Hispanic or Latino, and Asian HCWs compared with White HCWs. These findings suggest that interventions focused on addressing vaccine hesitancy among HCWs are needed.

Abstract
BACKGROUND HIV can interrupt the normal development of bone marrow cell lines. Bone marrow aspiration/biopsy (BMA/B) has been described as a diagnostic tool in AIDS patients with fever of unknown origin (FUO). In this review, we aimed to study patients with AIDS who had undergone a BMA/B to investigate FUO and describe the pathologies diagnosed in the biopsy. METHODS Thirty-four BMA/B samples were collected from AIDS patients admitted for work-up of FUO to the infectious disease ward of a tertiary referral HIV center in Tehran, Iran, between September 2014 and September 2015. Data including age, sex, duration of disease, CD4 cell counts, hepatitis B (HBV) and C (HCV) coinfection, the primary presentation of AIDS, and the treatment history were retrieved and analyzed. Patients underwent BMA/B. An expert pathologist reviewed the BMA/B specimens. RESULTS The mean age of the patients was 37.5 years (range, 26-56), and 27 (79%) were men. Twenty-seven (79%) patients contracted HIV from injection drug use, and 7 (21%) via sexual transmission. Only 3 (9%) of the BMA/B examinations were normal. Hypocellular bone marrow was diagnosed in 22 (65%) patients. Other pathologies included granulomas in 6 (18%), hematologic malignancies in 2 (6%), and leishmaniasis Aspergillosis, each in 1 (3%) patient. Six (17%) of the specimens were found to have tuberculosis infections. CONCLUSION Hypocellular bone marrow was the most common pathology on BMA/B examinations, followed by the presence of granulomas. Tuberculosis, Aspergillosis, and Leishmaniasis the opportunistic infections diagnosed on BMA/B specimens. Our results support BMA/B as an appropriate diagnostic tool for early diagnosis of opportunistic infections and malignancies in AIDS. BMA/B is indispensable in the armament of diagnostic tools of the physicians managing AIDS patients.

Abstract
BACKGROUND COVID-19 has spread globally with remarkable speed, and currently, there is limited data available exploring any aspect of the intersection between HIV and SARSCoV- 2 co-infection. OBJECTIVE To estimate the prevalence of clinical symptoms associated with COVID-19 among people living with HIV (PLWH) in Tehran, Iran. DESIGN Cross-sectional study. METHODS A total of 200 PLWH were recruited through the positive club via sampling, and completed the symptom-based questionnaire for COVID-19, which was delivered by trained peers. RESULTS Of 200 participants, respiratory symptoms, including cough, sputum, and shortness of breath, were the most prevalent among participants, but only one person developed symptoms collectively suggested COVID-19 and sought treatments. CONCLUSION It appears that existing infection with HIV or receiving antiretroviral treatment (ART) might reduce the susceptibility to the infection with SARS-CoV-2 or decrease the severity of the infection acquired. Further research is needed to understand causal mechanisms.

Abstract
:
Iran has been one of the active countries fighting against HIV/AIDS in the Middle East
during the last decades. Moreover, there is a strong push to strengthen the national health management
system concerning HIV prevention and control. In Iran, HIV disease has its unique features,
from changes in modes of transmission to improvement in treatment and care programs, which can
make it a good case for closer scrutiny. The present review describes the HIV epidemic in Iran from
the first case diagnosed until prevention among different groups at risk and co-infections. Not only
we addressed the key populations and community-based attempts to overcome HIV-related issues in
clinics, but we also elaborated on the efforts and trends in society and the actual behaviors related to
HIV/AIDS. Being located in the Middle East and North Africa (MENA) region, given the countryspecific
characteristics, and despite all the national efforts along with other countries in this region,
Iran still needs to take extra measures to reduce HIV transmission, especially in health education.
Although Iran is one of the pioneers in implementing applicable and appropriate policies in the
MENA region, including harm reduction services to reduce HIV incidence, people with substance
use disorder continue to be the majority of those living with HIV in the country. Similar to other
countries in this region, the HIV prevention and control programs aim at 90-90-90 targets to eliminate
HIV infection and reduce the transmission, especially the mother-to-child transmission and
among other key populations.

Abstract
The outbreak of the novel coronavirus that began in late December 2019 was announced as a pandemic by the World Health Organization as the number of cases is increasing exponentially throughout the globe. We presented a patient with confirmed SARS-CoV-2 pneumonia developing symmetric polyneuropathy. To our knowledge, extrapulmonary clinical presentations of 2019 novel coronavirus disease (COVID-19) have rarely been reported. This case highlights the possible association between SARS-CoV-2 infection and nervous system involvement.

Abstract
BACKGROUND Preventing unintended pregnancy is an important issue for women undergoing bariatric surgery, not only to avoid an adverse fetal outcome but to also ensure maximum weight loss for mother. Current guidelines strongly advise to use a reliable method of contraception following surgery and to delay pregnancy for 12-18 months after surgery. CASE PRESENTATION We present the case of a woman who underwent laparoscopic sleeve gastrectomy while she was unknowingly pregnant. She was monitored closely throughout her pregnancy for maternal-fetal wellbeing and delivered a healthy full-term girl. At her last follow-up visit 6 months post-delivery, both mother and infant were in good general condition and the mother achieved 94.4% excess weight loss. CONCLUSIONS In all-female patients of childbearing age planning to undergo bariatric surgery, pregnancy should be avoided by using a reliable method of contraception well before surgery. Pregnancy should also be excluded on the day of surgery.

Abstract
This study set to assess the involvement of dorsal hippocampus (CA1) serotonergic system on harmane induced memory acquisition deficit. We used one trial step-down inhibitory avoidancetask to evaluate memory retention and then, open field test to evaluate locomotor activity in adult male NMRI mice. The results showed that pre-training intra-peritoneal (i.p.) administration of harmane (12mg/kg) induced impairment of memory acquisition. Pre-training intra-CA1 administration of 5-HT1B/1D receptor agonist (CP94253; 0.5 and 5ng/mouse) and 5-HT2A/2B/2C receptor agonist (α-methyl 5-HT; 50ng/mouse) impaired memory acquisition. Furthermore, intra-CA1 administration of 5-HT1B/1D receptor antagonist (GR127935; 0.5ng/mouse) and 5-HT2 receptor antagonist (cinancerine; 5ng/mouse) improved memory acquisition. In addition, pre-training intra-CA1 injection of sub-threshold dose of CP94253 (0.05ng/mouse) and α-methyl 5-HT (5ng/mouse) potentiated impairment of memory acquisition induced by harmane (12mg/kg, i.p.). On the other hand, pre-training intra-CA1 infusion of sub-threshold dose of GR127935 (0.05ng/mouse) and cinancerine (0.5ng/mouse) with the administration of harmane (12mg/kg, i.p.) weakened impairment of memory acquisition. Moreover, all above doses of drugs did not change locomotor activity. The present findings suggest that there is an interaction between harmane and the CA1 serotonergic system in modulation of memory acquisition.

Abstract
The incidence and prevalence of obesity are fast increasing worldwide. Various indices have been used to measure and assess obesity. The body mass index (BMI) is the most common and practical of these indices. Overweight and obesity exert considerable adverse effects on the cardiovascular system. These effects are mediated through various neurohormonal and cytokine pathways, most of which are inflammatory mediators. Systolic and / or diastolic heart failure is more prevalent among obese and overweight individuals than among normal weight people. The concept of the "obesity paradox" has been proposed by some previously published studies, in which the prognosis of obese patients with established cardiovascular diseases, especially heart failure, is better than that of their leaner counterparts. In this review, we discuss the obesity paradox and its possible pathophysiologic mechanisms.

Abstract
INTRODUCTION Several lines of evidence support the contribution of autoimmune mechanisms in the pathogenesis of Meniere's disease. The aim of this study was determining the association between HLA-Cw Alleles in patients with definite Meniere's disease and patients with probable Meniere's disease and a control group. MATERIALS AND METHODS HLA-Cw genotyping was performed in 23 patients with definite Meniere's disease, 24 with probable Meniere's disease, and 91 healthy normal subjects, using sequence specific primers polymerase chain reaction technique. The statistical analysis was performed using stata 8 software. RESULTS There was a significant association between HLA-Cw*04 and HLA-Cw*16 in both definite and probable Meniere's disease compared to normal healthy controls. We observed a significant difference in HLA-Cw*12 frequencies between patients with definite Meniere's disease compared to patients with probable Meniere's disease (P=0.04). The frequency of HLA-Cw*18 is significantly higher in healthy controls (P=0.002). CONCLUSION Our findings support the rule of HLA-Cw Alleles in both definite and probable Meniere's disease. In addition, differences in HLA-Cw*12 frequency in definite and probable Meniere's disease in our study's population might indicate distinct immune and inflammatory mechanisms involved in each condition.

Abstract
BACKGROUND AND OBJECTIVES Postoperative bleeding has a great clinical importance and can contribute to increased mortality and morbidity in patients undergoing coronary artery bypass graft surgery. In this prospective, randomized, double-blind study, we evaluated the effect of prophylactic administration of fibrinogen concentrate on post-coronary artery bypass graft surgery bleeding. METHODS A total of 60 patients undergoing coronary artery bypass surgery were randomly divided into two groups. Patients in the fibrinogen group received 1g of fibrinogen concentrate 30 min prior to the operation, while patients in the control group received placebo. Post-operative bleeding volumes, prothrombin time, partial thromboplastin time, INR, hemoglobin and transfused blood products in both groups were recorded. A strict red blood cell transfusion protocol was used in all patients. RESULTS There were no significant differences between intra-operative packed red blood cells infusion in the studied groups (1.0±1.4 in fibrinogen group, and 1.3±1.1 in control group). Less postoperative bleeding was observed in the fibrinogen group (477±143 versus 703±179, p=0.0001). Fifteen patients in the fibrinogen group and 21 in the control group required post-op packed red blood cells infusion (p=0.094). No thrombotic event was observed through 72 h after surgery. CONCLUSION Prophylactic fibrinogen reduces post-operative bleeding in patients undergoing coronary artery bypass graft.

Abstract
INTRODUCTION Etomidate causes pain when injected intravenously. In this study we sought to determine if pretreatment by ondansetron reduces the pain on injection of etomidate. METHODS In this randomized, double blinded, placebo-controlled clinical trial, 20 patients of both sexes aged between 18 and 50 years of American Society of Anesthesiologists (ASA) physical status class I or II, whom were candidates for various elective surgical procedures and need more than one intravenous access were enrolled in the study. On arrival to the operating room two 22 gauge cannulas were inserted into veins on the dorsum of both hands. Following the infusion of 100mL normal saline into both intravenous lines, using an elastic band, venous drainage of hands was occluded at midarm. The patients were administered 8 mg (2 mL) of ondansetron into one hand and 2 mL of 0.9% saline into the other hand at the same time. The elastic band was removed after 1 min and 2mg (1 mL) of etomidate was administered at the same rate simultaneously into intravenous lines. The patients were asked to give a score of pain based on a verbal analog scale (VAS) to each hand. RESULTS A total number of 20 patients were studied (male = 55%, female = 45%). The mean age of the participants was 37.5 ± 13.1 years old and the mean weight was 67.7 ± 7.3 kg. The mean VAS for injection pain of etomidate after pre-administration of intravenous ondansetron was 1.5 ± 1.2 which was lower compared to pre-administration of placebo (3.2 ± 2.8, p < 0.05). CONCLUSION This study illustrates that pre-treatment with intravenous ondansetron significantly reduces the pain on injection of etomidate.
