Abstract
Background The nature of the healthcare workers’ jobs standing at the frontline against the coronavirus disease 2019 (COVID-19) puts them at a higher risk of unknowingly contracting the disease and potentially contributing to the spread. This study aims to assess the overall positive seroconversion prevalence of SARS-CoV-2. Methods This is a longitudinal cohort study of healthcare workers at Johns Hopkins Aramco Healthcare (JHAH). JHAH is a tertiary hospital located in Dhahran serving patients in several districts in the Eastern Province of Saudi Arabia. Participants were recruited between June and December 2020. Each participant had a serology blood test and completed the World Health Organization’s risk factor assessment questionnaire. Results This study included 682 participants working in JHAH, representing 15.7% of our population. Out of the 682 participants, 15.2% had a positive SARS-CoV-2 rt-PCR before taking part in the study. However, only 87 tested positive for SARS-CoV-2 antibodies, a prevalence of 12.7% of all participants. Out of the 87 positives for SARS-CoV-2 antibodies, 17 participants never tested positive for COVID-19 rt-PCR, a prevalence of 2.9%. Moreover, not properly using alcohol-based hand rub or soap and water after the risk of body fluid exposure and wearing personal protective equipment when indicated were found to be statistically significant to having a positive SARS-CoV-2 IgG assay. Conclusion Positive seroconversion rate was considerably low during the first wave of COVID-19 amongst JHAH’s healthcare workers and similar to other healthcare organizations in Saudi Arabia. Seropositivity correlated significantly with following infection prevention and control recommendations. Clinicaltrials.gov Identifier NCT04469647.

Abstract
BACKGROUND Cervical cancer (cca) is largely a preventable disease if women receive regular screening, which allows for the detection and treatment of preinvasive lesions before they become invasive. Having been inadequately screened is a common finding among women who develop cca. Our primary objective was to determine the Pap screening histories of women diagnosed with cca in Montreal, Quebec. Secondary objectives were to determine the characteristics of women at greatest risk of cca and to characterize the level of physician contact those women had before developing cca. METHODS The Invasive Cervical Cancer Study, a population-based case-control study, consisted of Greater Montreal residents diagnosed with histologically confirmed cca between 1998 and 2004. Respondents to the 2003 Canadian Community Health Survey and a sample of women without cca obtained from Quebec medical billing records served as controls. RESULTS During the period of interest, 568 women were diagnosed with cca. Immigrants and women speaking neither French nor English were at greatest risk of cca. Most of the women in the case group had been screened at least once during their lifetime (84.8%-90.4%), but they were less likely to have been screened within 3 years of diagnosis. Having received care from a family physician or a medical specialist other than a gynecologist within the 5 years before diagnosis was associated with a greater risk of cca development. CONCLUSIONS Our findings provide evidence of the need for an organized population-based screening program. They also underscore the need for provider education to prevent missed opportunities for cca screening when at-risk women seek medical attention.

Abstract
Uterine papillary serous carcinoma (UPSC) is an aggressive variant of endometrial cancer characterized by a high recurrence rate and poor prognosis. Several studies have demonstrated that UPSC has a tendency to manifest with extra-uterine disease, even for tumors which appear to be limited to the endometrium. The data on adjuvant chemotherapy for stage I UPSC are limited, and the available studies are generally under-powered to assess if chemotherapy improves survival. However, we believe that, patients with UPSC should receive complete surgical staging, including omentectomy and peritoneal biopsies, and then until the results of larger series or randomized controlled trials will be available, we feel that combined radiotherapy and chemotherapy is justified for all stage I UPSC.

Abstract
Human papillomavirus (HPV) infection is associated with high-grade vulvar intraepithelial neoplasia (VIN-3). The prevalence of anogenital HPV infection in women with previously treated VIN-3 has not been documented yet. This cross-sectional study compared high-risk HPV DNA detection rates in women with past (n = 30) and current (n = 22) VIN-3 to those without current or past VIN (n = 86). HPV DNA was detected in vulvar and cervical samples with Hybrid Capture 2 (HC-2). Smoking was associated in multivariate analysis with current VIN-3 (odds ratio (OR) 8.3, 95% confidence interval (CI) 2.0-8.2) and any VIN-3 history (OR 6.5, 95% CI 2.5-16.5). High-risk HPV DNA was found on the vulva of 64%, 33%, and 20% of women with current VIN-3, past VIN-3, and without previous or current VIN, respectively. After controlling for age and smoking, high-risk HPV vulvar infection was associated with cervical high-risk HPV infection (OR 8.6, 95% CI 2.8-26.5; P = 0.001). After controlling for age, HPV infection was more often multifocal in women with current VIN-3 compared to women with previous but no current VIN-3 lesion (OR 17.6, 95% CI 1.4-227.2). Multifocal vulvar HPV infection was detected in women with previous or active VIN-3. Longitudinal studies are required to determine if the multifocality of HPV infection on the vulva could explain the high recurrence rate of VIN-3.

Abstract
OBJECTIVE This study evaluates the safety and outcome of a minimally invasive technique for inserting a standard dynamic hip screw for intertrochanteric fractures. HYPOTHESIS The use of standard plate in a minimally invasive technique is both possible and advantageous to patient outcome. DESIGN AND METHODS Prospective surgeon-randomized blinded outcome clinical study comparing new technique to conventional technique. MAIN OUTCOME MEASURE Pain, operative time and mean hemoglobin drop in percutaneous hip fixation. RESULTS The minimally invasive technique had significantly less blood loss (P < 0.001), operative time (P < 0.001) and a trend to less morphine use. CONCLUSIONS Minimal invasive technique significantly reduces blood loss and operative time for fixation of intertrochanteric hip fractures without sacrifice of fixation stability or bone healing.
