ABSTRACT
BACKGROUND: Previous reviews on hysterectomy versus uterine-sparing surgery in pelvic organ prolapse (POP) repair did not consider that the open abdominal approach or transvaginal mesh use have been largely abandoned. OBJECTIVES: To provide up-to-date evidence by examining only studies investigating techniques currently in use for POP repair. SEARCH STRATEGY: MEDLINE and Embase databases were searched from inception to January 2023. SELECTION CRITERIA: We included randomized and non-randomized studies comparing surgical procedures for POP with or without concomitant hysterectomy. Studies describing open abdominal approaches or transvaginal mesh implantation were excluded. DATA COLLECTION AND ANALYSIS: A random effect meta-analysis was conducted on extracted data reporting pooled mean differences and odds ratios (OR) between groups with 95% confidence intervals (CI). MAIN RESULTS: Thirty-eight studies were included. Hysterectomy and uterine-sparing procedures did not differ in reoperation rate (OR 0.93; 95% CI 0.74-1.17), intraoperative major (OR 1.34; 95% CI 0.79-2.26) and minor (OR 1.38; 95% CI 0.79-2.4) complications, postoperative major (OR 1.42; 95% CI 0.85-2.37) and minor (OR 1.18; 95% CI 0.9-1.53) complications, and objective (OR 1.38; 95% CI 0.92-2.07) or subjective (OR 1.23; 95% CI 0.8-1.88) success. Uterine preservation was associated with a shorter operative time (-22.7 min; 95% CI -16.92 to -28.51 min), shorter hospital stay (-0.35 days, 95% CI -0.04 to -0.65 days), and less blood loss (-61.7 mL; 95% CI -31.3 to -92.1 mL). When only studies using a laparoscopic approach for both arms were considered, no differences were observed in investigated outcomes between the two groups. CONCLUSIONS: No major differences were observed in POP outcomes between procedures with and without concomitant hysterectomy. The decision to preserve or remove the uterus should be tailored on individual factors.
ABSTRACT
There is evidence that diet and nutrition are modifiable risk factors for several cancers. In recent years, attention paid to micronutrients in gynecology has increased, especially regarding Human papillomavirus (HPV) infection. We performed a review of the literature up until December 2022, aiming to clarify the effects of micronutrients, minerals, and vitamins on the history of HPV infection and the development of cervical cancer. We included studies having as their primary objective the evaluation of dietary supplements, in particular calcium; zinc; iron; selenium; carotenoids; and vitamins A, B12, C, D, E, and K. Different oligo-elements and micronutrients demonstrated a potential protective role against cervical cancer by intervening in different stages of the natural history of HPV infection, development of cervical dysplasia, and invasive disease. Healthcare providers should be aware of and incorporate the literature evidence in counseling, although the low quality of evidence provided by available studies recommends further well-designed investigations to give clear indications for clinical practice.
ABSTRACT
BACKGROUND: The arterial switch operation (ASO) for transposition of the great arteries has excellent survival, but a substantial number of patients suffer from a reduced exercise capacity. The goal of this study was to identify imaging parameters associated with a reduced exercise capacity in patients after ASO. METHODS: A retrospective analysis was performed of ASO patients who underwent cardiopulmonary exercise testing (CPET) between 2007 and 2017. Reduced exercise performance was defined as a reduced workload peak (Wpeak) with Z-score <-2 or a peak oxygen uptake indexed for weight (VO2peak/kg) with Z-score <-2. Data on echocardiography and cardiac magnetic resonance performed within 1 year of the CPET were collected for comparison. RESULTS: A total of 81 ASO patients (age 17±7 years) were included. Reduced exercise performance was found in 22 patients (27%) as expressed by either a reduced Wpeak and/or a reduced VO2peak/kg. Main pulmonary artery gradient and tricuspid regurgitation gradient by echocardiography were found to be associated with reduced Wpeak (p=0.031; p=0.020, respectively). The main pulmonary artery gradient and tricuspid regurgitation gradient by echocardiography were found to be associated with reduced VO2peak/kg (p=0.009; p=0.019, respectively). No left ventricular parameters were found to be associated with abnormal exercise performance. CONCLUSION: This study demonstrates that ASO patients frequently experience reduced exercise capacity. Echocardiographic evidence of main pulmonary artery stenosis and increased right ventricular pressure were associated with reduced exercise capacity, and are therefore key to monitor during serial follow-up of ASO patients.
