ABSTRACT
In today's world, high variability of body mass index (BMI) is known as a significant global health problem that can lead to many negative impacts on the cardiovascular system, including atrial fibrillation (AF) and coronary heart disease. The current systematic review aims to elucidate the effect of variability in BMI on the risk of cardiovascular outcomes. Four databases, including PubMed, Scopus, MEDLINE, and CENTRAL, were searched. All related articles up to 10 June 2022, were obtained. Titles, abstracts, and full texts were reviewed. After screening abstracts and full texts, four articles were included in our study. In these four cohort studies, 7,038,873 participants from the USA and South Korea were involved. These articles generally considered the BMI and outcomes including cardiovascular disease, AF, and coronary heart disease. All these articles reported an association between the variability of BMI and increased risk of cardiovascular outcomes. Due to the negative impact of the high variability of BMI on the risk of cardiovascular outcomes, health policymakers and practitioners should pay more attention to the significant role of BMI in health problems and physicians might better check the variability of BMI visits to visit.
ABSTRACT
BACKGROUND: Cesarean delivery rates are increasing globally, raising concerns about associated complications such as isthmocele. Isthmoceles are pouch-like defects in the anterior uterine wall at the site of a prior cesarean delivery scar. OBJECTIVE: This study aimed to determine isthmocele prevalence, associated symptoms, and risk factors among women with a history of cesarean delivery. STUDY DESIGN: This cross-sectional study evaluated 297 women with prior cesarean delivery using transvaginal ultrasound to screen for isthmocele. Data on demographics, pregnancy details, comorbidities, and indications for cesarean delivery were collected. Isthmocele was defined sonographically as any niche or defect at the hysterotomy site. Descriptive and comparative analyses identified factors associated with isthmocele. RESULTS: Isthmocele prevalence was 65.3% (n=194). Abnormal vaginal bleeding was reported in 21.1% of participants, pelvic pain by 4.1% of participants, and both by 4.1% of participants. Compared to women without isthmocele, those with isthmocele were older (35.9 vs 31.6 years), had higher body mass index (26.8 vs 25.5 kg/m2), gravidity (1.8 vs 1.3), and parity (1.7 vs 1.2). Repeat cesarean delivery was more common (30.4% vs 12.6%) and elective cesarean delivery less common (33.5% vs 67.9%) among those with isthmocele. CONCLUSION: Over half of the women with history of cesarean delivery had an isthmocele. Abnormal bleeding was common. Advanced maternal age, obesity, repeat procedures, and certain comorbidities appear to increase risk. Further research on prevention and treatment is warranted given the high prevalence.
ABSTRACT
AIMS: The skin, as the body's largest organ, plays vital roles in sensory functions, temperature regulation, and protection against pathogens and injuries. Skin wounds, which disrupt its integrity, can result from various factors, including diseases such as diabetes. Diabetic foot ulcers are a severe complication of diabetes, often leading to amputations. This systematic review explores the therapeutic potential of silver nanoparticles in the management of diabetic ulcers. METHODS: Seven studies published between 2016 and 2023 were included in this review. Also, 4 studies were included in the meta-analysis. These studies investigated the application of silver nanoparticles, primarily in dressing forms, for diabetic ulcer treatment. A systematic search strategy was employed, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. RESULTS: The results show that silver nanoparticles do not have a significant difference in improving DFU healing rates. SilvrSTAT Gel, a dressing containing silver nanoparticles, outperformed traditional dressings, leading to a substantial percentage of ulcers healing within weeks. Comparative studies also indicated that silver nanoparticles were at least as effective as alternative treatments, such as nano-chitosan dressings, and showed potential for combination therapy with growth factors. DISCUSSION: This review underscores the promise of silver nanoparticles, a nanotechnology-based approach, in accelerating the healing of diabetic ulcers while providing antimicrobial benefits. Despite some limitations, including variations in treatment regimens and a lack of long-term outcome data, these findings show there is no clinical evidence for using Nanosilver for the healing process of DFU. CONCLUSION: Silver nanoparticles currently do not have sufficient clinical evidence for healing the DFU; however, in some studies, they had noticeable effects on the rate of wound healing.
ABSTRACT
BACKGROUND: Cesarean scar pregnancy, an uncommon ectopic pregnancy in which the embryo is implanted in the cesarean scar, poses significant risks without prompt diagnosis and treatment. Its prevalence has risen alongside increased cesarean section rates. Despite various treatment approaches, consensus remains elusive. Ultrasonography, particularly contrast-enhanced ultrasonography, shows promise in cesarean scar pregnancy diagnosis. MAIN BODY: This systematic review, following PRISMA guidelines, explores contrast-enhanced ultrasound's diagnostic potential in cesarean scar pregnancy. We searched PubMed, Scopus, Web of Science, and Google Scholar up to August 2023. Selection involved two stages: title/abstract screening and full-text assessment. The included studies investigated contrast-enhanced ultrasound's diagnostic value in cesarean scar pregnancy, provided adequate data, and were peer-reviewed in English. Quality assessment followed the QUADAS-2 criteria. We extracted the diagnostic accuracy metrics: sensitivity, specificity, and accuracy. Out of 193 records, five studies met the inclusion criteria (2016-2020, China). Contrast-enhanced ultrasound displayed sensitivities of 77%-100% and specificities of 95%-100%. Two studies reported accuracy of 96.9%-97.8%. Compared with conventional ultrasound, contrast-enhanced ultrasound exhibited superior sensitivity, specificity, and accuracy. It also outperformed transvaginal ultrasound. CONCLUSION: Enhanced-contrast ultrasound holds promise for diagnosing and managing cesarean scar pregnancy by visualizing scar vascularization in real-time, thereby reducing severe complication risks. This review highlights contrast-enhanced ultrasound as a transformative diagnostic tool for cesarean scar pregnancy management, despite existing evidence limitations.
