RESUMEN
Pregnancy-related syncope presents special difficulties due to the rapid physiological changes that occur throughout gestation. This narrative review provides a thorough summary of the patterns and pregnancy outcomes secondary to syncope during pregnancy. There is an increase in syncope burden during pregnancy, and hence it is critical that medical professionals understand the significance of syncope during pregnancy. Syncope can have a negative impact on the health of the mother as well as the fetus. Therefore, this review summarizes data from studies on syncope in pregnancy. It includes observational studies, case reports, and review articles. Early detection and proper management are very important because pregnant women who experience cardiac syncope are at risk of unfavorable neonatal and maternal outcomes. The review reveals diverse trends in syncope incidence during pregnancy, emphasizing the need for a nuanced understanding of temporal variations. Risks of injury, uteroplacental insufficiency, psychological effects, interruptions in prenatal treatment, possible aggravation of pre-existing diseases, and lifestyle changes are examples of immediate maternal repercussions. Pregnancy-related syncope is a complex condition that affects the health of the mother and the fetus. The study stresses the need for careful clinical treatment due to the rapid results and the diversity in incidence patterns. The unique component of a possible relationship to the brain health of offspring justifies further investigation in this area.
RESUMEN
Over the years, several studies have revealed an important link between thyroid disorders and gallstone disease. According to these studies, hypothyroidism and hyperthyroidism are associated with cholesterol gallstone disease. This association between thyroid hormone disorders and cholesterol gallstone disease is due to the importance of thyroid hormones on cholesterol synthesis, bile functioning and content, and gallbladder motility. Several genes and receptors have been found on the thyroid gland, liver, and gallbladder to verify this association. These genes affect thyroid hormone secretion, lipid metabolism, and bile secretion. Defects in these various gene expression and protein functions lead to bile duct diseases. Other causes that lead to cholesterol gallstone disease are supersaturation of the bile with cholesterol and impaired gallbladder motility, which leads to bile stasis. This article has discussed these factors in detail while highlighting the association between thyroid hormones and cholesterol gallstone disease.
RESUMEN
Vitamin D, a fat-soluble vitamin, acts in the calcium and phosphorus metabolism in its active form (1,25-dihydroxy vitamin D). It may help prevent and treat autoimmune diseases, including diabetes mellitus. Diabetes has become a significant global health issue with a rising incidence and prevalence. A recent focus has been on vitamin D supplementation as part of efforts to discover novel ways to prevent and treat diabetes. Most evidence points to the vitamin D receptors (VDRS) gene in both types of diabetes. The main objective of this study is to analyze how vitamin D affects both type 1 and type 2 diabetes. In this literature review, we searched the PubMed and Google Scholar databases to collect related articles from 13 papers of different study designs. We found a significant association between vitamin D deficiency and type 1 and type 2 diabetes development. It has been shown that vitamin D supplements have a promising effect in reducing glycated hemoglobin (HbA1c) in patients with type 1 diabetes, with no significant impact on the incidence or improvement of type 2 diabetes. Patients with diabetes and people at high risk of diabetes need the appropriate amount of vitamin D; therefore, regular testing and vitamin D supplementation are advised for the management and prevention of diabetes. Additional randomized studies with bigger sample sizes and longer-term trials are required to fully explore the benefits of vitamin D supplementation in patients with type 1 and type 2 diabetes.
RESUMEN
BACKGROUND: Spontaneous pneumomediastinum (SPM) is a rare condition defined by the presence of air in the mediastinum in the absence of traumatic or iatrogenic injury. Although the imaging findings and complications of SARS-CoV-2 infection have been reported many times, there are few reports of the prevalence and outcomes of patients with SPM. PURPOSE: In this paper, we aimed to illustrate the different manifestations, management, and outcome of three cases of SPM in COVID-19 patients and provide an extensive review available literature. MATERIALS AND METHODS: Detailed report of patients' demographics, clinical presentation, management, and outcome of three cases of COVID-19 induced SPM seen in our institution was provided. Additionally, literature search was employed through March 2021 using Pubmed and Google scholar databases where a total of 22 articles consisting of 35 patients were included. RESULTS: Statistical analysis of the reviewed articles showed that SPM in COVID-19 occurs in patients with a mean age of 55.6 ± 16.7 years. Furthermore, 80% of the 35 patients are males and almost 60% have comorbidities. Intriguingly, SPM in COVID-19 is associated with a 28.5% mortality rate. These findings are consistent with our case series and are different from previous reports of SPM in non-COVID-19 cases where it most commonly occurs in younger individuals and has a self-limiting course with a good outcome. CONCLUSION: Therefore, SPM in COVID-19 patients occurs in older patients and is potentially associated with a higher mortality rate. Further studies are necessary to assess its role as a prognostic marker of poor outcome.

OBJECTIVE: To assess the value of phase contrast magnetic resonance imaging cerebrospinal fluid flowmetry in differentiating between normal pressure hydrocephalus and involutional atrophy. METHODS: The descriptive case-control study was conducted at the Al-Yarmouk Teaching Hospital, Baghdad, Iraq, from April to December 2017, and comprised patients with normal pressure hydrocephalus and involutional brain changes. Healthy volunteers were included as controls. Demographic data was recorded and the patients were divided according to age. Conventional magnetic resonance imaging of the brain was performed followed by the assessment of cerebrospinal fluid flow dynamics, was done at the level of the aqueduct of Sylvius. Data was analysed using SPSS 25. RESULTS: Of the 23 subjects with a mean age of 52.3}16.8 years (range: 25-75 years), There were 13(56.5%) males and 10(43.5%) were females. Also, there were 17(74%) patients and 6(26%) controls. Among the patients, 8(47%) had brain atrophic changes based on magnetic resonance imaging, and 9(53%) had normal pressure hydrocephalus signs clinically and scanning criteria. Flowmetry showed mean systolic velocity 1.5}0.3 cm\sec, peak systolic velocity 1.5}0.3 cm\sec and systolic stroke volume 28.5}4.7µLin the control group which was significantly different from the patients (p<0.001). CONCLUSIONS: Phase-contrast magnetic resonance imaging was found to be a useful tool to differentiate between normal pressure hydrocephalus and age-related brain atrophy.

BACKGROUND: Prosthetic treatment of the posterior edentulous maxilla may require bone augmentation to enable the placement and integration of dental implants. This constitutes a complex healing situation, and resorption of the grafted bone and failure of the implants often occurs. The application of platelet-rich plasma (PRP) has been suggested to improve incorporation and preservation of bone grafts. OBJECTIVE: The objective was to assess the effectiveness of PRP on the implant failure and complication rate, when used as an adjunctive material with bone graft in sinus floor augmentation. METHOD AND MATERIALS: An electronic search of two databases (PubMed and Cochrane) was performed to identify randomized controlled trials (RCTs) in patients requiring sinus augmentation and implant placement in the posterior edentulous maxilla with or without using PRP as an adjunctive material to the bone graft. Data were extracted independently by two reviewers. The Cochrane tool was used for assessing the quality of included studies. Meta-analysis was performed for the included RCTs. RESULTS: Nine RCTs were identified, four of which were included in the study. Three of these trials were judged to be at unclear risk of bias and one was at low risk of bias. The meta-analysis revealed no difference between the PRP versus non-PRP groups regarding implant failure and complication rate. CONCLUSION: The meta-analysis revealed no statistically significant difference regarding implant failure and complication rate of implants placed in the atrophic posterior maxilla with sinus floor augmentation with or without PRP as an adjunctive material to the bone graft. This finding should be interpreted with great caution given the serious numerical limitations of the included studies.

BACKGROUND: Cancer incidence in Middle Eastern countries, most categorized as low- and middle-income, is predicted to double in the next 10 years, greater than in any other part of the world. While progress has been made in cancer diagnosis/treatment, much remains to be done to improve palliative care for the majority of patients with cancer who present with advanced disease. OBJECTIVE: To determine knowledge, beliefs, barriers, and resources regarding palliative care services in Middle Eastern countries and use findings to inform future educational and training activities. DESIGN: Descriptive survey. SETTING/SUBJECTS: Fifteen Middle Eastern countries; convenience sample of 776 nurses (44.3%), physicians (38.3%) and psychosocial, academic, and other health care professionals (17.4%) employed in varied settings. MEASUREMENTS: Palliative care needs assessment. RESULTS: Improved pain management services are key facilitators. Top barriers include lack of designated palliative care beds/services, community awareness, staff training, access to hospice services, and personnel/time. The nonexistence of functioning home-based and hospice services leaves families/providers unable to honor patient wishes. Respondents were least satisfied with discussions around advance directives and wish to learn more about palliative care focusing on communication techniques. Populations requiring special consideration comprise: patients with ethnic diversity, language barriers, and low literacy; pediatric and young adults; and the elderly. CONCLUSIONS: The majority of Middle Eastern patients with cancer are treated in outlying regions; the community is pivotal and must be incorporated into future plans for developing palliative care services. Promoting palliative care education and certification for physicians and nurses is crucial; home-based and hospice services must be sustained.
