Exploring Lived Experiences of Vulnerability in Nursing Management during the Coronavirus Disease 2019 Pandemic: A Phenomenological Study of Nurse Managers and Nurses.

Introduction: The Coronavirus Disease 2019 (COVID-19) pandemic placed enormous pressure on healthcare systems around the world, but it also provided valuable insights for healthcare organizations during this challenging period. Objective: This study aimed to explore nurses' lived experiences of vulnerability in hospital nursing management during the COVID-19 pandemic, and reflect on the lessons learned. Methods: In this phenomenological study, 14 participants, including nurse managers at different levels and staff nurses, were selected by purposive sampling from one center university hospital. Data collection was done through in-depth individual semistructured interviews with participants and a review of weekly reports of crisis management meetings at the university hospital. Interviews were analyzed using Colaizzi's method in seven phases by MAXQDA software Version 10. Results: One overarching theme, four themes, and 15 subthemes were obtained from analyses of interviews. Four themes of "nurses' attrition," "distrust of society to the organization," "fragility in the organization's performance," and "intensified inequalities" were extracted as threats to nursing management at the hospital. Subsequently, the weekly reports of crisis management meetings at the university hospital were analyzed to extract the solutions and lessons. Conclusion: The unpreparedness of the healthcare system against a crisis can led to the loss of organizational assets, including medical staff and the credibility of the healthcare system. Limitations of the infrastructure at hospital became more obvious during the pandemic and caused serious threats to the healthcare system. Despite severe challenges along with the pandemic, it offered four valuable lessons in nursing management.

Prenatal exposure to ambient air pollution and risk of fetal overgrowth: Systematic review of cohort studies.

OBJECTIVES: Fetal overgrowth has detrimental effects on both the mother and the fetus. The global issue of ambient air pollution has been found to contribute to fetal overgrowth through various pathways. This study aimed to identify the association between prenatal exposure to ambient air pollution and the risk of fetal overgrowth. METHODS: We identified articles between January 2013 and February 2024 by searching the Web of Sciences(WoS), PubMed, Proquest, Scopus, and Google Scholar databases. Quality assessment was performed using the Newcastle Ottawa scale. This review was provided based on the PRISMA guideline and registered with PROSPERO, "CRD42023488936". RESULTS: The search generated 1719 studies, of which 22 cohort studies were included involving 3,480,041 participants. Results on the effects of air pollutants on fetal overgrowth are inconsistent because they vary in population and geographic region. But in general, the results indicate that prenatal exposure to air pollutants, specifically PM2.5, NO2, and SO2, is linked to a higher likelihood of fetal overgrowth(macrosomia and large for gestational age). Nevertheless, the relationship between CO and O3 pollution and fetal overgrowth remains uncertain. Furthermore, PM10 has a limited effect on fetal overgrowth. It is essential to consider the time that reproductive-age women are exposed to air pollution. Exposure to air pollutants before conception and throughout pregnancy has a substantial impact on the fetus's vulnerability to overgrowth. CONCLUSIONS: Fetal overgrowth has implications for the health of both mother and fetus. fetal overgrowth can cause cardiovascular diseases, obesity, type 2 diabetes, and other diseases in adulthood, so it is considered an important issue for the health of the future generation. Contrary to popular belief that air pollution leads to intrauterine growth restriction and low birth weight, this study highlights that one of the adverse consequences of air pollution is macrosomia or LGA during pregnancy. Therefore governments must focus on implementing initiatives that aim to reduce pregnant women's exposure to ambient air pollution to ensure the health of future generations.

Electromagnetic fields exposure on fetal and childhood abnormalities: Systematic review and meta-analysis.

Today, in the modern world, people are often exposed to electromagnetic waves, which can have undesirable effects on cell components that lead to differentiation and abnormalities in cell proliferation, deoxyribonucleic acid (DNA) damage, chromosomal abnormalities, cancers, and birth defects. This study aimed to investigate the effect of electromagnetic waves on fetal and childhood abnormalities. PubMed, Scopus, Web of Science, ProQuest, Cochrane Library, and Google Scholar were searched on 1 January 2023. The Cochran's Q-test and I 2 statistics were applied to assess heterogeneity, a random-effects model was used to estimate the pooled odds ratio (OR), standardized mean difference (SMD), and mean difference for different outcomes, and a meta-regression method was utilized to investigate the factors affecting heterogeneity between studies. A total of 14 studies were included in the analysis, and the outcomes investigated were: change in gene expression, oxidant parameters, antioxidant parameters, and DNA damage parameters in the umbilical cord blood of the fetus and fetal developmental disorders, cancers, and childhood development disorders. Totally, the events of fetal and childhood abnormalities were more common in parents who have been exposed to EMFs compared to those who have not (SMD and 95% confidence interval [CI], 0.25 [0.15-0.35]; I 2, 91%). Moreover, fetal developmental disorders (OR, 1.34; CI, 1.17-1.52; I 2, 0%); cancer (OR, 1.14; CI, 1.05-1.23; I 2, 60.1%); childhood development disorders (OR, 2.10; CI, 1.00-3.21; I 2, 0%); changes in gene expression (mean difference [MD], 1.02; CI, 0.67-1.37; I 2, 93%); oxidant parameters (MD, 0.94; CI, 0.70-1.18; I 2, 61.3%); and DNA damage parameters (MD, 1.01; CI, 0.17-1.86; I 2, 91.6%) in parents who have been exposed to EMFs were more than those in parents who have not. According to meta-regression, publication year has a significant effect on heterogeneity (coefficient: 0.033; 0.009-0.057). Maternal exposure to electromagnetic fields, especially in the first trimester of pregnancy, due to the high level of stem cells and their high sensitivity to this radiation, the biochemical parameters of the umbilical cord blood examined was shown increased oxidative stress reactions, changes in protein gene expression, DNA damage, and increased embryonic abnormalities. In addition, parental exposure to ionizing and non-ionizing radiation can lead to the enhancement of different cell-based cancers and developmental disorders such as speech problems in childhood.

Treatment of Hydatidiform Mole Suspected to COVID 19.

The aim of this study was to report a case of the treatment of hydatidiform mole in Coronavirus pandemic in Iranshahr. A 17-year-old primiparous woman with gestational age of 14 weeks presented with unilateral leg swelling and sudden abdominal distension beginning in the night before referring to the health center. In the abdominal examination of the patient by a healthcare provider, the baby's heartbeat was not heard and a mismatch was observed between gestational age and fundal height, which corresponded to approximately 24 weeks of gestation. She was conscious and pale with hematuria and uterine contractions. After inserting two IV lines, the patient immediately underwent monitoring and was visited by a gynecologist. Complete molar pregnancy was diagnosed with an enlarged heterogeneous uterus 180 cm × 90 cm in size and containing 170 mm × 80 mm cysts. The treatment began with vancomycin AMP, hydrocortisone AMP, oseltamivir CAP 75 mg, kaletra CAP 200 mg, and meropenem AMP.

Effect of electromagnetic field on abortion: A systematic review and meta-analysis.

BACKGROUND: The increasing use of new technologies by pregnant women inevitably exposes them to the risks of the electromagnetic fields (EMFs). According to the World Health Organization, EMFs are the major sources of pollutants which harm human health. This study was aimed to evaluate the effects of EMF exposure on abortion. METHODS: Web of Science, Cochrane Library, MEDLINE, PubMed, EMBASE, Scopus, and Google Scholar were searched until 2021. Pooled odds ratio (OR) with 95% confidence interval (CI) was estimated using a random-effects model. Heterogeneity was explored using Cochran's Q test and I 2 index. A meta-regression method was employed to investigate the factors affecting heterogeneity between the studies. The Newcastle-Ottawa scale was used to assess the credibility of the studies. RESULTS: Eligible studies (N = 17) were analyzed with a total of 57,693 participants. The mean maternal age (95% CI) was 31.06 years (27.32-34.80). Based on meta-analysis results, the pooled estimate for OR of EMF with its effects was 1.27 (95% CI: 1.10-1.46). According to the results of meta-regression, sample size had a significant effect on heterogeneity between studies (p: 0.030), but mother's age and publication year had no significant effect on heterogeneity (p-value of bothwere >0.05). No publication bias was observed. CONCLUSION: Exposure to EMFs above 50 Hz or 16 mG is associated with 1.27× increased risk of abortion. It may be prudent to advise women against this potentially important environmental hazard. Indeed, pregnant women should receive tailored counselling.
