Descent of the uterus is a major etiology of uterine prolapse. However, true cervical elongation can cause uterine prolapse without uterine descent. The aim of study was to investigate the clinical outcomes of Manchester operation in patients with uterine prolapse caused by "true cervical elongation," compared with vaginal hysterectomy (VH). Medical records of patients who underwent Manchester operation or VH from 2006 to 2015 were reviewed. True cervical elongation was defined on the basis of C point of the Pelvic Organ Prolapse Quantification (POP-Q) system ≥0 and D point ≤-4, as well as estimated cervical length of ≥5 cm. The primary outcome was recurrence of pelvic organ prolapse (POP) evaluated by POP-Q system. The outcomes of two groups were compared after propensity score matching, for age, parity, and preoperative POP-Q stage. During the study period, 23 patients underwent Manchester operation and 374 patients underwent VH. The recurrence rate of POP (p=0.317) and complication rate were not statistically significant different between the two study groups. Manchester operation exhibited shorter operation time than VH (p=0.033). In subgroup analysis (POP-Q stage III), body mass index [odds ratio (OR)=1.74; 95% confidence interval (CI), 1.08-2.81] and not having concurrent anterior colporrhaphy (OR for concurrent anterior colporrhaphy, 0.06; 95% CI, 0.01-0.75) were identified as significant risk factors for recurrence of POP. The Manchester operation technique seems to be an effective and safe alternative procedure for the treatment of uterine prolapse caused by true cervical elongation, compared with VH.

Postoperative management after major lung surgery is critical. This study evaluates risk factors for predicting mandatory intensive care unit (ICU) admission immediately after major lung resection. We retrospectively reviewed patients for whom the surgeon requested an ICU bed before major lung resection surgery. Patients were classified into three groups. Univariable and multivariable logistic regression analyses were performed, and a clinical nomogram was constructed. Among 340 patients, 269, 50, and 21 were classified into the no need for ICU, mandatory ICU admission, and late-onset complication groups, respectively. Predictive postoperative diffusion capacity of the lung for carbon monoxide (47.2 (interquartile range (IQR) 43.3–65.7)% versus vs. 67.8 (57.1–79.7)%; p = 0.003, odds ratio (OR) 0.969, 95% confidence interval (CI) 0.95–0.99), intraoperative blood loss (400.00 (250.00–775.00) mL vs. 100.00 (50.00–250.00) mL; p = 0.040, OR 1.001, 95% CI 1.000–1.002), and open thoracotomy (p = 0.030, OR 2.794, 95% CI 1.11–7.07) were significant predictors for mandatory ICU admission. The risk estimation nomogram demonstrated good accuracy in estimating the risk of mandatory ICU admission (concordance index 83.53%). In order to predict the need for intensive care after major lung resection, preoperative and intraoperative factors need to be considered.

Prognostic nutritional index (PNI) reflects the nutritional and immunologic status of the patients. The clinical application of PNI is already well-known in various kinds of solid tumors. However, there is no study investigating the relationship between PNI and oncological outcome of the resected ampulla of Vater (AoV) cancer. From January 2005 to December 2012, the medical records of patients who underwent pancreaticoduodenectomy for pathologically confirmed AoV cancer were retrospectively reviewed. Long-term oncological outcomes were compared according to the preoperative PNI value. A total of 118 patients were enrolled in this study. The preoperative PNI was 46.13±6.63, while the mean disease-free survival was 43.88 months and the mean disease-specific survival was 55.3 months. In the multivariate Cox analysis, initial CA19-9 (p = 0.0399), lymphovascular invasion (p = 0.0031), AJCC 8^th N-stage (p = 0.0018), and preoperative PNI (p = 0.0081) were identified as significant prognostic factors for resected AoV cancer. The disease-specific survival was better in the high preoperative PNI group (≤48.85: 40.77 months vs. >48.85: 68.05 months, p = 0.0015). A highly accurate nomogram was developed based on four clinical components to predict the 1, 3, and 5-year disease-specific survival probability (C-index 0.8169, 0.8426, and 0.8233, respectively). In resected AoV cancer, preoperative PNI can play a significant role as an independent prognostic factor for predicting disease-specific survival.

Objective: The aim of this study was to determine the prevalence of high-risk (HR) and vaccine-type human papillomavirus (HPV) infection among Thai schoolgirls who were not included in the national HPV immunization program.Methods: Cross-sectional surveys were conducted among grade 10 (15-16 years old) and grade 12 (17-18 years old) schoolgirls in two provinces of Thailand. Urine samples were collected using the Colli-PeeRO device from November 2018 to February 2019. The samples were initially tested using CobasRO 4800. Subsequently, all Cobas-positive samples and 1:1 matched Cobas-negative samples were tested by Anyplex RO assay. Prevalences of any HPV, any HR HPV, vaccine-type HPV, and individual HR HPV types were estimated by school grade.Results: Prevalences of any HPV and any HR HPV were 11.6% and 8.6% for grade 10, and 18.5% and 12.4% for grade 12 schoolgirls, respectively. Prevalences of bivalent vaccine-type HPV infection in grades 10 and 12 were 3.4% and 4.5%, respectively. Prevalences of quadrivalent and nonavalent vaccine-type HPV infections were 4.0%/6.6% and 6.4%/10.4% in grades 10 and 12, respectively. HPV16 was the most common type detected, followed by HPV58, 51, and 52. Circulating HR HPV types were similar between the school grades.Conclusion: A substantial burden of HR HPV infections was found among unvaccinated high school girls in Thailand.
