RESUMEN

Combating the ongoing coronavirus disease 2019 (COVID-19) pandemic demands accurate, rapid, and point-of-care testing with fast results to triage cases for isolation and treatment. The current testing relies on reverse transcriptase PCR (RT-PCR), which is routinely performed in well-equipped laboratories by trained professionals at specific locations. However, during busy periods, high numbers of samples queued for testing can delay the test results, impacting efforts to reduce the infection risk. Besides, the absence of well-established laboratories at remote sites and low-resourced environments can contribute to a silent spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). These reasons compel the need to accommodate point-of-care testing for COVID-19 that meets the ASSURED criteria (affordable, sensitive, specific, user-friendly, rapid and robust, equipment-free, and deliverable). This study assessed the agreement and accuracy of the portable Biomeme SARS-CoV-2 system against the gold standard tests. Nasopharyngeal and nasal swabs were used. Of the 192 samples tested using the Biomeme SARS-CoV-2 system, the results from 189 samples (98.4%) were in agreement with the reference standard-of-care RT-PCR testing for SARS-CoV-2. The portable system generated simultaneous results for nine samples in 80 min with high positive and negative percent agreements of 99.0% and 97.8%, respectively. We performed separate testing in a sealed glove box, offering complete biosafety containment. Thus, the Biomeme SARS-CoV-2 system can help decentralize COVID-19 testing and offer rapid test results for patients in remote and low-resourced settings.

RESUMEN

OBJECTIVE: To determine the local rates of massive intraoperative blood loss and subsequent infectious morbidity for patients undergoing gynaecologic laparotomy. METHODS: We performed a retrospective chart review of all patients undergoing gynaecologic laparotomy between January 1, 2013 and December 31, 2013 to identify cases of massive intraoperative blood loss (defined as ≥1 L estimated intraoperative blood loss, a postoperative reduction in hemoglobin concentration of ≥40 g/L, or a perioperative blood transfusion). For cases meeting these criteria, we abstracted further data to assess the rate of postoperative infectious morbidity (defined as a positive wound swab culture, positive urine culture, or satisfying the 1991 criteria for systemic inflammatory response syndrome). RESULTS: The rate of massive intraoperative blood loss was 13.5% (n = 69). The average age in this cohort was 50.4 years (range 18-84 years) and the average BMI was 27.9 kg/m2. Perioperative transfusion was required in 31.9% (n = 22). Notably, 26.1% of patients (n = 18) met one of our primary endpoints for postoperative infectious morbidity. A further 10.1% (n = 7) had morbidities including hyponatremia, wound dehiscence, intra-abdominal abscess, positive blood cultures, acute respiratory distress syndrome, myocardial infarction, intensive care unit admission, or death. CONCLUSION: Our rate of massive intraoperative blood loss during gynaecologic laparotomy was found to be 13.5%, and our rate of postoperative infectious morbidity subsequent to massive intraoperative blood loss was 26.1%.

RESUMEN

Objective To evaluate the gender proportion in academic obstetrics and gynecology faculty across the United States and Canada and further assess any gender differences in academic ranks, leadership positions, and research productivity. Methods Obstetrics and gynecology programs were searched from the Fellowship and Residency Electronic Interactive Database (FREIDA) (n=145) and the Canadian Resident Matching Service (CaRMS) (n=13) to compile a database of gender and academic profiles of faculty physicians with Medical Doctorate (MD) or Doctors of Osteopathic Medicine (DO) degrees. Elsevier's Scopus was used to gather individual research metrics for analysis, and the data were analyzed using Strata v14.2 (StataCorp. 2015. Stata Statistical Software: Release 14. College Station, TX: StataCorp LP). Results Among 3556 American and 689 Canadian Obstetrics and Gynaecology physicians, women comprised 60.9% and 61.4%, respectively. Among physicians with professorships, women physicians comprised 36.2% and 35.8% in the United States and Canada, respectively. When examining the gender proportion of physicians in leadership roles, women comprised 52.2% and 56.1% in the United States and Canada, respectively. The h-index between men and women physicians showed a significant difference overall in both the United States (p<0.001) and Canada (p<0.001), indicating that men have higher academic output. Conclusion Although the overall proportion of women academic staff physicians in Obstetrics and Gynaecology is higher than the proportion of men, there are more men who had a full professor rank. Men also had higher academic productivity.

RESUMEN

PURPOSE: The purpose of the study was to determine knowledge, practice, and resources available to primary care physicians to diagnose and manage corneal abrasion in Saudi Arabia. METHODS: This cross-sectional survey was held in 2017. Family physicians and emergency physicians attending an international conference were surveyed. The questions related to demography, invagination, and tools available in their institute were collected. The questionnaire on how to diagnose and how they manage case of corneal abrasion was also collected using tablet-based software. RESULTS: Two hundred and twenty-five participants participated in the survey. Exposure to eye patients in two-third of participants was too low (93; 39.6%). Resources for diagnosing corneal abrasion were available in limited centers (51; 21.7%). The rate of good practice to manage corneal abrasion was 21.2% (95% confidence interval 16.0; 26.5). Certified emergency physicians (P < 0.001) and western and central regions (P < 0.001) were positively associated with good practice. Availability of slit lamp (P = 0.2) was not significantly associated with the level of practice to manage corneal abrasion. Fluorescein staining and use of cobalt blue light are essential for diagnosing corneal abrasion as per 40% of participants. About 44.7% of participants replied that antibiotics and lubricants should be used to treat. Nearly one-fourth of participants suggested urgent reference to the ophthalmologist. Use of specific antibiotic varied widely; however, ofloxacin was the main choice of antibiotic in treating corneal abrasion. CONCLUSION: The knowledge and practice among physicians about corneal abrasion were low. Integrating primary eye care into emergency services through provision of required resources and training physicians is recommended.

RESUMEN

BACKGROUND: The Coronavirus Disease 2019 (COVID-19) outbreak has affected all regions and countries with varying impacts based on infection rates and the associated fatalities. This study aimed to assess knowledge, attitude, and practices (KAP) toward the COVID-19 pandemic among Saudi Arabians. METHODS: The study utilized a cross-sectional research design. Web-based questionnaires' link was sent via emails and social media and sample was 5483 respondents. Purposive sampling ensured only those participants that met the inclusion criteria. Validity and reliability were checked. RESULTS: Most respondents, 67.9%, were aged between 18 and 35 years and highest level of education university. The findings based on the study objectives indicated a high level of knowledge about COVID-19, which indicated early detection can improve treatment by 4701 (85.7%), the disease can be treated at home 84.6%, the disease can be prevented and avoided when precautions are taken 96.8%. Moreover, 37.2% of the respondents still used herbal products to prevent and treat the disease, and 72.1% indicating immediate visit the physician when there are symptoms. CONCLUSION: Promoting public knowledge about COVID-19 by the Ministry of Health is paramount in defeating this disease. Providing more education and awareness for public to comply with WHO's recommendation is recommended.

RESUMEN

BACKGROUND: The management of a patient refusing blood transfusion who subsequently experiences a severe postpartum hemorrhage is a particular clinical challenge. CASE: A 30-year-old nulliparous patient (who was a Jehovah's Witness) had labour induced for post-dates at 41+4 weeks' gestational age after an uncomplicated pregnancy. She delivered by Caesarean section for dystocia and suspected chorioamnionitis, and subsequently developed postpartum hemorrhage that required management with oxytocin, ergometrine, carboprost, uterine artery ligation, and Hayman compression sutures. The patient ultimately required two additional visits to the operating room, culminating in hysterectomy. Use of tranexamic acid, recombinant factor VIIa, and Tisseel was instrumental in halting the ongoing hemorrhage. CONCLUSION: Optimal management of a patient refusing administration of blood products requires a multidisciplinary approach as well as a combination of traditional and novel therapies.
