Radiotherapy for Cervical Cancer in Patients with Systemic Lupus Erythematosus

Objective To determine the toxicity and efficacy of radiotherapy for cervical cancer in patients with systemic lupus erythematosus (SLE). Methods Medical records of patients with SLE who received radiation for cervical cancer from January 2011 to January 2019 were reviewed. For definitive radiotherapy, a dose of 50.4 Gy in 28 fractions was delivered by intensity-modulated radiation therapy (IMRT) combined with high-dose-rate brachytherapy of 28 to 30 Gy in 5 fractions. A dose of 45 to 50.4 Gy in 25–28 fractions was delivered for postoperative radiation. All patients were in remission with or without a low dosage of prednisone or immunosuppressive medication. Survival data were analyzed with the Kaplan–Meier method. The incidence of severe toxicities among patients was compared with the chi-square test or Fisher’s exact test. Results Twelve patients with SLE were included in this study. Definitive radiotherapy was delivered in 7 patients with FIGO (2009) stage II–III disease. Five patients with FIGO I disease received postoperative radiation. The median follow-up time was 22.1 months. The 3-year overall survival (OS) and 3-year progression-free survival (PFS) were 77.8% and 83.3%, respectively. One patient of definitive radiotherapy and one patient of postoperative radiation died due to distant metastasis of cervical cancer. Grade 3 or higher acute and chronic reactions occurred in 58.3% and 8.3% patients, respectively. Acute grade 3 or higher toxicity correlated with the presence of chemotherapy (p = 0.045). Conclusion Modern radiotherapy for cervical cancer was well tolerated in SLE patients with remission and provided a favorable outcome.
Short hairpin RNA attenuates liver fibrosis by regulating the PPAR-γ and NF-κB pathways in HBV-induced liver fibrosis in mice

Progressive liver fibrosis, caused by chronic viral infection and metabolic disorders, results in the development of cirrhosis and hepatocellular carcinoma. However, no antifibrotic therapies have been approved to date. In our previous study, adeno-associated virus (AAV) short hairpin RNAs (shRNAs) targeting hepatitis B virus (HBV) and transforming growth factor (TGF)-β administration could persistently inhibit HBV replication and concomitantly prevent liver fibrosis. However, the differentially expressed proteins and critical regulatory networks of AAV-shRNA treatment remain unclear. Accordingly, in the present study, we aimed to analyze differentially expressed proteins in the liver of AAV-shRNA-treated mice with HBV infection and liver fibrosis using isobaric tags for relative and absolute quantitation (iTRAQ)-based quantitative proteomics and to elucidate the underlying antifibrotic mechanisms. In total 2,743 proteins were recognized by iTRAQ-based quantitative proteomics analysis. Gene Ontology analysis revealed that the differentially expressed proteins mostly participated in peptide metabolism in the biological process category, cytosolic ribosomes in the cell component category, and structural constituents of ribosomes in the molecular function category. Kyoto Encyclopedia of Genes and Genomes pathway analysis indicated that oxidative stress and the peroxisome proliferator-activated receptor (PPAR) signaling pathway were activated after treatment. Verification studies revealed that AAV-shRNAs inhibited hepatic stellate cell activation and inflammation by suppressing nuclear factor-κB p65 phosphorylation and α-smooth muscle actin expression via upregulation of PPAR-γ. Hepatocytes steatosis was also decreased by activating the PPAR signaling pathway and improving lipid metabolism. The expression level of TGF-β was decreased due to upregulation of PPAR-γ expression and direct inhibition using AAV-shRNA targeting TGF-β. TGF-β-induced oxidative stress was suppressed by increasing glutathione S-transferase Pi 1 and reducing peroxiredoxin 1. Collectively, the present results indicated that AAV-shRNAs were effective in modulating liver fibrosis by reducing oxidative stress, inflammation and activating the PPAR signaling pathway.
LncRNA LINC01116 Contributes to Cisplatin Resistance in Lung Adenocarcinoma

Background Long non-coding RNAs (lncRNAs) have been found to contribute to cisplatin resistance in several cancers; however, the role of lncRNA LINC01116 in cisplatin resistance remains unknown in non-small-cell lung cancer. This study aimed to examine the contribution of LINC01116 to cisplatin resistance in lung adenocarcinoma (LAD). Materials and Methods Cisplatin-resistant A549/DDP cells were generated by treatment with cisplatin by dose escalation. LINC01116 expression was compared between A549 and A549/DDP cells, and between cisplatin-resistant and non-resistant LAD specimens. The cell viability, colony formation, proliferation, migration and invasion were measured using MTT and Transwell assays, and cell apoptosis and cell cycle were detected using flow cytometry. The expression of E-cadherin and Vimentin was quantified. LAD xenografts were modeled in nude mice to investigate the role of LINC01116 on the resistance of LAD to cisplatin. Results MTT assay measured the IC50 values of 13.49 ± 1.62 and 3.52 ± 1.33 μg/mL for A549/DDP and A549 cells, respectively. LINC01116 was overexpressed in cisplatin-resistant LAD specimens and A549/DDP cells (P < 0.05). Knockdown of LINC01116 inhibited cell viability, proliferation, migration and invasion, promoted apoptosis and enhanced the sensitivity to cisplatin in A549/DDP cells, while LINC01116 overexpression promoted cell viability, proliferation, migration and invasion, inhibited apoptosis and reduced the sensitivity to cisplatin in A549 cells. LINC01116 knockdown resulted in a 2.1-fold increase in E-cadherin expression and a 56% reduction in Vimentin expression in A549/DDP cells, and LINC01116 overexpression resulted in a 45% reduction in E-cadherin expression and a 1.82-fold increase in Vimentin expression in A549 cells. Conclusion Dysregulation of lncRNA LINC01116 expression results in resistance of LAD to cisplatin via the EMT process. Our findings support the oncogenic role of LINC01116 to promote the development of cisplatin resistance in LAD, and LINC01116 may be a novel predictor of poor response to cisplatin.
Prevalence and Predictors of Virological Failure Among Adults Living with HIV in South Wollo Zone, Northeast Ethiopia: A Retrospective Cohort Study

Background Highly active antiretroviral therapy has dramatically altered progression of HIV infection and significantly improved patients’ quality of life. However, drug resistance with consequent treatment failure raises the need for much more expensive and toxic second-line regimens. Thus, this study aimed at investigating the predictors of virologic failure among adults in Northeast Ethiopia. Methods A retrospective cohort study was carried out among adults who started first-line antiretroviral treatment from September 2005 to January 2018. Data were collected from patients’ medical records, entered and validated using EpiData version 3.1 and then exported to SPSS version 20 for analysis. Binary logistic regression was carried out; odds ratio with 95% CI was used to identify covariates associated with virologic failure. Statistical significance was considered at p-value <0.05. Results A total of 384 patients with mean age of 35.73±9.44 years were consecutively enrolled; of which, 213 (55.5%) were females, 255 (66.4%) had WHO clinical stage III/IV, and 130 (33.9%) had baseline CD4 count <100 cells/mm3. Mean baseline CD4 count was 179 cells/mm3 (range: 2–853 cells), and 158 (41.1%) participants were on AZT/3TC/NVP. Virological failure was diagnosed among 61 (15.9%) patients. The mean time to virologic failure after initiation of ART was 63.80 months (range: 17–150 months). After adjusting for other confounders, risk of experiencing virologic failure was significantly associated with being divorced (AOR 3.40, 95% CI 1.20–9.59), being naïve to ART (AOR 2.55, 95% CI 1.23–5.28), low (<100) baseline CD4 count (AOR 2.39, 95% CI 1.03–5.54) and nonadherence (AOR 6.73, 95% CI 3.29–13.76). Conclusion In this study, the prevalence of antiretroviral treatment failure was 15.9%. Being divorced, being naïve to antiretroviral therapy, low (<100 cells/mm3) baseline CD4 count and nonadherence were found to be significant predictors of virologic failure. ART programs should focus on early HIV diagnosis and ART initiation as well as enhanced adherence support.
Violence Against Healthcare Workers at Primary Care Centers in Dammam and Al Khobar, Eastern Province, Saudi Arabia, 2019

Purpose Workplace violence is common throughout the world. It causes many serious problems in the healthcare sector, where it significantly impacts healthcare workers, the services provided, and organizations as a whole. However, few studies have investigated these issues in Saudi Arabia. This study examined the prevalence of violence against healthcare workers at primary care centers in Dammam and Al Khobar, in the Eastern Province of Saudi Arabia. The study also assessed the types, perpetrators, perceived causes, and consequences related to such violence. Here, the aim was to understand how healthcare workers responded to violence and gauge their awareness of a reporting system. Patients and Methods A total of 360 healthcare workers (180 each from primary care centers in Dammam and Al Khobar) were invited to complete structured, self-administered questionnaires. As such, this study employed a cross-sectional analytical design. Results The prevalence of workplace violence among all participating health workers was 46.9%, with approximately 90% of these workers reporting verbal violence, 34.3% having been subject to intimidation, and 3% reporting physical violence. Approximately 75% reported that violent events were initiated by patients, while 45.6% reported that the events were initiated by patients’ companions. Healthcare workers’ reactions included reporting events to their supervisors or the police, but 46.7% said they did nothing; the most common reason was perceived inefficacy. Finally, only 36.4% of all participants were aware of a violence reporting system. Conclusion This study showed that healthcare workers were commonly exposed to different forms of violence, but often either did not react to it or did not report it. Further, there was relatively little awareness of how to manage and report workplace violence, thus indicating the need for healthcare workers to receive relevant education and training. A national program should also be established to track and prevent workplace violence.
MicroRNA-623 Inhibits Epithelial–Mesenchymal Transition to Attenuate Glioma Proliferation by Targeting TRIM44

Objective Glioma has the highest incidence among the different tumor types within the nervous system, accounting for about 40% of them. Malignant glioma has a high invasion and metastasis rate, which leads to the poor prognosis of patients. By targeting specific genes, microRNAs serve as key regulators in the epithelial–mesenchymal transformation (EMT) process, which could provide new insights into the treatment of glioblastomas (GBM). The detailed molecular role that miR-623 plays in GBM still remains unclear. Materials and Methods The level of miR-623 in GBM cells was evaluated by RT-PCR. The function of miR-623 overexpression on GBM cell proliferation, migration, and invasion was assessed by MTS, Transwell analysis, and colony formation assay. In addition, a mouse subcutaneous xenograft model was used to study in vivo effects. The binding between miR-623 and TRIM44 was verified by a dual-luciferase reporter assay and the regulatory function of miR-623 on EMT markers was evaluated using Western blot. Results The expression of miR-623 was repressed in the GBM cancer cell lines. MiR-623 overexpression or TRIM44 knockdown attenuated the proliferation, migration, and invasion of GBM cell lines. TRIM44 could facilitate the reverse suppression of EMT and miR-623 in GBM progression. MiR-623 was found to inhibit TRIM44 expression by directly binding to its 3ʹUTR. In addition, systemic delivery of miR-623 mimic reduced tumor growth and inhibited TRIM44 protein expression in tumor-bearing nude mice. Furthermore, our findings indicated that miR-623 overexpression or TRIM44 down-regulation impeded the proliferation and migratory ability of LN229 and U251MG glioma cells, and miR-623 attenuates TRIM44-induced EMT by directly targeting the 3ʹUTR of TRIM44, which could serve as preliminary research to identify potential therapeutic targets for future treatment of GBM. Conclusion Overall, microRNA-623 inhibits epithelial–mesenchymal transition to attenuate glioma proliferation by targeting TRIM44.
Self-Medication Practice and Associated Factors Among University of Gondar College of Medicine and Health Sciences Students: A Cross-Sectional Study

Purpose Self-medication is the use of medicines by individuals to treat self-recognized illnesses or symptoms without any medical supervision. Such practices may cause antimicrobial resistance, which causes treatment failure, economic loss, serious health hazards, missed diagnosis, delayed appropriate treatment, drug dependency, and adverse drug effects. However, empirical evidence is limited to the current status of its practices and associated factors among university students. Thus, the aim of this study was to assess the magnitude and associated factors of self-medication practices among medicine and health science students at the University of Gondar. Methods An institution-based cross-sectional study was employed from February to March 2017. A total of 792 randomly selected students were surveyed with a self-administered structured questionnaire. Epi Info version 7 and SPSS version 20 were used for data entry and analysis, respectively. Binary logistic regression analysis was performed. In multivariable analysis, P-value <0.05 and adjusted odds ratio (AOR) with 95% confidence interval (CI) were used to identify associated factors. Results Self-medication practice was found to be 52.4% (95% CI: (49%, 56%)) among university students. For most students, the major reason for using self-medication was taking the illness as less serious (71.1%). Females (AOR: 1.48; 95% CI: 1.08–2.01), income category (USD 44.01–175.87) (AOR: 0.47; 95% CI: 0.29–0.78), sixth year students (AOR: 8.71; 95% CI: 4.04–18.77) and health officer students (AOR: 2.36; 95% CI: 1.20–4.63) were found to be significantly associated with self-medication practice. Conclusion More than half of the students practiced self-medication, which is moderately higher than other findings. Gender, income, year of study, and field of study were the major factors that affected self-medication. Therefore, interventions that can halt the high magnitude of self-medication and factors associated with it are crucial. Special attention should be given to students who stay in the university for longer years.

Paclitaxel Suppresses Hepatocellular Carcinoma Tumorigenesis Through Regulating Circ-BIRC6/miR-877-5p/YWHAZ Axis

Background Paclitaxel is an effective chemotherapeutic agent for the treatment of cancer patients. Accumulating evidence suggests that circular RNAs (circRNAs) play critical roles in the occurrence and development of human cancers. However, there are few studies on interactions between paclitaxel and circRNAs in hepatocellular carcinoma (HCC). Materials and Methods Cell counting kit-8 (CCK-8) assay and colony formation assay were conducted to determine cell proliferation. Cell apoptosis was assessed by flow cytometry. The expression levels of circRNA baculoviral IAP repeat-containing 6 (circ-BIRC6), microRNA-877-5p (miR-877-5p), and tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein, zeta (YWHAZ) were detected by quantitative real-time polymerase chain reaction (qRT-PCR). The mice xenograft model was established to investigate the roles of circ-BIRC6 and paclitaxel in vivo. The interaction between miR-877-5p and circ-BIRC6 or YWHAZ was predicted by bioinformatics analysis and verified by dual-luciferase reporter assay. Western blot assay was applied for measuring the protein expression of YWHAZ. Results Paclitaxel suppressed HCC tumorigenesis through decreasing cell proliferation and accelerating apoptosis. Circ-BIRC6 and YWHAZ were upregulated, and miR-877-5p was downregulated in HCC tissues and cells. Paclitaxel treatment inhibited the expression of circ-BIRC6 and YWHAZ while promoted the expression of miR-877-5p. Circ-BIRC6 overexpression or miR-877-5p interference reversed the inhibitory effect of paclitaxel on HCC tumorigenesis. Moreover, miR-877-5p could specially bind to YWHAZ, and its knockdown abated the suppressive effect of circ-BIRC6 depletion on HCC tumorigenesis. Additionally, YWHAZ was identified as a direct target of miR-877-5p. Besides, circ-BIRC6 functioned as a molecular sponge of miR-877-5p to regulate YWHAZ expression. Conclusion Paclitaxel limited HCC tumorigenesis via modulating circ-BIRC6/miR-877-5p/YWHAZ axis, providing a novel therapeutic approach for the treatment of HCC.
The mental health of emergency services personnel in the UK Biobank: a comparison with the working population

ABSTRACT Background: There is evidence that mental disorders are more frequently reported among emergency services personnel due to the stressful nature of the job in combination with a high exposure to traumatic events. However, most of this research is based on occupational surveys that may lead to a contextual bias in the prevalence estimates or lack an adequate comparison group. Objectives: To investigate mental health outcomes and associations with individual, job and trauma related characteristics among emergency services personnel compared to other workers. Method: Participants were identified from the UK Biobank, a large study that collected a variety of genetic, physical and health data on individuals from across the UK. UK Biobank participants were aged between 40–69 years at recruitment. Those employed in the emergency services were identified based on job titles. A comparison sample of other workers was selected and matched to the gender composition of emergency services personnel. Results: 5052 participants were included, and 842 were currently working in the emergency services. The majority were male (77.4%) and the mean age at Biobank enrolment was 52.5 years. Alcohol misuse was reported in 32.8% of emergency services personnel compared to 29.2% in non-emergency services personnel, followed by PTSD (9.2% vs 6.0%), depression (6.8% vs 5.1%) and anxiety (3.9% vs 3.6%). An increased risk of PTSD was found among emergency services personnel compared to other workers (odds ratio 1.58, 95% confidence interval 1.21–2.06), but this association was no longer significant after adjustment for exposure to traumatic events and job characteristics. Conclusions: The substantial levels of alcohol misuse and increased risk of PTSD, possibly as a result of traumatic exposures in the line of duty in combination with job stressors such as shift work, call for continued monitoring of the health and wellbeing of emergency services personnel.
Clinical Outcomes Following Tocilizumab Administration in Mechanically Ventilated Coronavirus Disease 2019 Patients

Supplemental Digital Content is available in the text. Objectives: Effective treatments for the critically ill patient with novel coronavirus disease 2019 are desperately needed. Given the role of cytokine release syndrome in the pathogenesis of coronavirus disease 2019-associated respiratory distress, therapies aimed at mitigating cytokine release, such as the interleukin-6 receptor-inhibiting monoclonal antibody tocilizumab, represent potential treatment strategies. Therefore, we examined the outcomes of critically ill coronavirus disease 2019 patients treated with tocilizumab and factors associated with clinical improvement. Design: A retrospective cohort analysis of 21-day outcomes for consecutive mechanically ventilated patients treated with tocilizumab from March 24, 2020, to May 4, 2020. Setting: Nine ICUs at six hospitals within a hospital system in Houston, Texas, United States. Patients: The first 62 coronavirus disease 2019 patients on invasive mechanical ventilation who were treated with tocilizumab, which was considered for all patients with severe disease. Interventions: Tocilizumab was administered either at a weight-based dose of 4–8 mg/kg or at a flat dose of 400 mg, with repeat administration in some patients at the physician’s discretion. Measurements and Main Results: The primary outcomes were mortality and clinical improvement, defined as extubation. By day 21 post-tocilizumab, clinical improvement occurred in 36 patients (58%) and 13 patients (21%) died. In both univariable and multivariable analyses, age less than 60 years was associated with clinical improvement. Transient transaminitis was the most common adverse reaction, occurring in 25 patients (40%). Conclusions: Based on clinical outcomes and mortality rates seen in previous reports of mechanically ventilated patients, tocilizumab, as part of the management strategy for severe coronavirus disease 2019, represents a promising option. These findings support the need for evaluation of tocilizumab in a randomized controlled trial.
Determinants of Anemia Among Pregnant Women Attending Antenatal Care Clinic at Public Health Facilities in Kacha Birra District, Southern Ethiopia

Background Anemia is accountable for 20% of maternal death globally, and it is associated with premature birth, low birth weight, and infant death. According to the WHO report of 2008, 57.1% of pregnant women were anemic in Africa. In Ethiopia, anemia among pregnant women is 62.7%. There were no data in the study area that identified the determinants of anemia. Objective To identify the determinants of anemia among pregnant mothers attending ANC clinic in public health facilities in Kacha Birra District, Southern Ethiopia. Methods An institutional-based unmatched case–control study was conducted among pregnant women attending antenatal care clinics in public health facilities in Kacha Birra District, Southern Ethiopia, from February 1/2019–May 30/2019. An aggregate of 117 cases and 227 controls were involved in the study. Data were collected using interviewer-administered questionnaires. Controls were pregnant ladies whose blood hemoglobin level was 11 g/dl and above at their first antenatal care clinic, and cases were pregnant ladies whose hemoglobin level less than 11 g/dl. Both bivariate and multivariable logistic regression models were used to isolate independent predictors of anemia. Results An overall of 344 respondents (117 cases and 227controls) were included in this study with a response rate of 100%. On multivariable logistic regression models, significant predictors of anemia were: rural residence [AOR= 2.9,95% CI:1.18–5.84], previous history of heavy menstrual blood flow [AOR=2.75, 95% CI: 2.66–28.53], age of mother [AOR=4.013, 95% CI: 1.08–14.90], parasitic infection [AOR=6.39, 95% CI: 1.226–33.362], food taboo (aversion) [AOR= 3.92, CI: 95% 2.08–7.35], drinking tea/coffee instantly after meal [AOR=18.49, 95% CI:6.89–40.64]. Conclusion Residence, previous heavy menstrual flow, age, parasitic infection, food taboo, and tea/coffee consumption immediately after meals were significant predictors of anemia among pregnant women. So, anemia prevention and control policy should include the promotion of counseling on the consumption of diversified and iron-enriched foods during pregnancy, prevention of parasitic infection as well as mass deworming, awareness creation on cultural norms that makes food aversion during pregnancy.
