Prevalence of Infectious Agents Causing Abortion in Pregnant Women Using Serological Tests and Histopathological Analysis

Background: Abortion is a spontaneous loss of pregnancy before 20 weeks. Approximately 42 million pregnancies end in abortion. The maternal infections that are transmissible from mother to fetus are caused by many pathogens, of which the TORCH complex contributes majorly to neonatal and infant deaths globally. The aim of this study is to detect the prevalence and types of infectious causes of abortion. One hundred aborted women admitted to King Faisal Medical Complex Maternity Hospital in Taif City between the period of 2018 and 2020 were enrolled in this study. The serological test reports (TORCH panel), as well as reports of hematological (CBC) and chemical parameters, were obtained from laboratory management system databases, reviewed, and then analyzed. The H&E-stained microscopic slides of their product of conception (POC) were examined under a microscope and compared with histopathological reports. The prevalence of TORCH infections was 8% in aborted women. Hepatitis B virus (HBV) and mixed TORCH infections constituted the highest percentage of TORCH pathogens in aborted women, constituting 6%. The most detected histopathological finding in seropositive cases (50%) was POC, with mixed inflammatory infiltrates and chronic endometritis, while in seronegative aborted women, POC was normal (64.1%). There is a statistically significant increase in the mean count of white blood cells in seropositive women. Therefore, it is important to provide health campaigns to bring awareness to the population about the risk factors of infectious agents to be avoided, especially during pregnancy

Enhancing knowledge and practices toward Vitamin D deficiency through implementing awareness programs among medical science female students

Objectives Vitamin D (VD) deficiency has widespread prevalence worldwide. In Saudi Arabia, it is the most common form of public health problem with regard to malnutrition. This is because there is insufficient knowledge about negative VD practices. The current study aimed to evaluate VD deficiency knowledge and practices before and after the implementation of an awareness programme. Methods A quasi-experimental design was used for the study, which was conducted at the College of Applied Medical Science at Al-Baha University. A convenience sample encompassing all the female students in the Public Health Department was used ( n = 83 students). Two tools were used for data collection; the first was an intervention questionnaire to assess the students’ knowledge, and the second was a questionnaire concerned with students’ practices in preventing VD deficiency. Results The mean age of the students was 20.75 ± 7.85 years. Of the study’s subjects, 45.8% suffered from VD deficiency and 72.3% had a family history of VD deficiency. The study showed that there had been significant progress in students’ VD knowledge and behaviours following the programme. While 59% of the students had poor knowledge and 95.2% had unsatisfactory practices pre-intervention, 86.7% and 48.2% showed exemplary knowledge and a positive attitude towards VD, respectively, post-intervention. The scores achieved by the students had significantly changed ( p ≤ .01); compared to the knowledge and practice scores of 24.43 ± 7.21 out of 53 and 24.29 ± 5.23 out of 48, respectively, before the intervention, they were elevated to 46.89 ± 9.93 and 29.39 ± 14.23 following the awareness programme. Conclusion This type of health education programme can raise VD deficiency knowledge and improve practices. This study highlights the importance of holding public health awareness campaigns and recommends the creation of specifically designed booklets and leaflets for medical students and patients/visitors to hospital and public places

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population
