Simple Summary: TOs are becoming an important marker not only for assessing hospital and surgeon performance, but also as a predictor of overall survival. As the number of surgeons who achieve the learning curve for laparoscopic resection of tumors in the posterosuperior section of the liver increases, the number of patients with TO will gradually increase with a subsequent improvement in overall survival. Achieving textbook outcomes (TOs) improves the short-term and long-term performance of a hospital. Our objective was to assess TOs in the laparoscopic liver resection (LLR) of tumors in the PS (posterosuperior) section of the liver and identify the impact of the learning curve. We conducted a retrospective cohort study analyzing patients who underwent LLR for lesions located in the PS segments. Patients were divided into a TO and no-TO group. TOs were defined as negative margins, no transfusion, no readmission, no major complications, no 30-day mortality, and a length of stay ≤ 50th percentile. Patients' outcomes were assessed in two study periods before and after 2015. TOs were achieved in 47.6% (n = 117). In multivariable analysis, obesity (p = 0.001), shorter operation time (p < 0.001), less blood loss (p < 0.001), normal albumin (p = 0.003), and minor resection (p = 0.046) were significantly associated with achieving TOs. Although the 5-year recurrence-free survival rate (p = 0.096) was not significantly different, the 5-year overall survival rate was significantly greater in the TO group (p = 0.001). Body mass index > 25 kg/m2 (p = 0.020), age > 65 years (p = 0.049), and achievement of TOs (p = 0.024) were independently associated with survival. The proportion of patients who achieved a TO was higher after 2015 than before 2015 (52.3% vs. 36.1%; p = 0.022). TOs are important markers not only for assessing hospital and surgeon performance but also as predictors of overall survival. As the number of surgeons who achieve the learning curve increases, the number of patients with TOs will gradually increase with a subsequent improvement in overall survival. [ABSTRACT FROM AUTHOR]

Simple Summary: In this retrospective study, we investigated the recurrence patterns and associated risk factors following curative resection. Peak recurrence occurred at 11 months, showing varied patterns based on tumor location, stage, and risk factors, such as vascular or perineural invasion, anastomotic leakage and circumferential resection margin involvement. Short-interval surveillance within the first 2 years after surgery, especially for high-risk patients in the early period, is warranted. This study aimed to assess recurrence patterns and related risk factors following curative resection of colorectal cancer (CRC). This retrospective observational study was conducted at a tertiary care center, including 2622 patients with stage I–III CRC who underwent curative resection between 2008 and 2018. Hazard rates of recurrence were calculated using a hazard function. The primary outcome was the peak recurrence time after curative resection and secondary outcomes were prognostic factors associated with recurrence. Over a median follow-up period of 53 months, the overall, locoregional and systemic recurrence rates were 8.9%, 0.7%, and 8.5%, respectively. Recurrence rates were significantly higher for rectal cancer (14.9% overall, 4.4% locoregionally, and 12.3% systemically) than for colon cancer (all p < 0.001). The peak recurrence time was 11 months, with variations in hazard rates and curves depending on the tumor location, stage, and risk factors. Patients with AL or CRM involvement exhibited a distinct pattern, with a high hazard rate in the early postoperative period. Understanding these recurrence patterns and risk factors is crucial for establishing effective postoperative surveillance strategies. Our findings suggested that short-interval surveillance should be considered during the first 2 years post-surgery, particularly for high-risk patients who should receive early attention.

The article discusses the study to evaluate the effect of maternal age on the cesarean section rate of twin pregnancies in late preterm and term gestation. It mentions that the cesarean section rate in twin pregnancies significantly increased as maternal age increased, even in multiparous women. Maternal old age was an independent risk factor for cesarean section after a labor trial in nulliparous and multiparous women after adjusting for confounding factors.

Background Context: Although risk factors of new adjacent vertebral fracture (AVF) and remote vertebral fracture (RVF) after vertebroplasty may differ, research on this topic is lacking.Purpose: To determine the natural course of new vertebral fractures after vertebroplasty for osteoporotic vertebral compression fracture (OVCF) and to analyze each risk factor for understanding the incidence of AVF and RVF.Study Design: Retrospective cohort study.Patient Sample: The study subjects included 205 patients who received vertebroplasty for OVCF and were followed-up for at least 1-year.Outcome Measures: Data on factors that could affect the occurrence of vertebral fractures, such as age, body mass index, and bone density, were collected from the patients' medical records. Fracture pattern, fracture location, sagittal imbalance, degree of segmental kyphosis after vertebroplasty, cement distribution, and cement leakage were radiologically examined.Methods: xDuring the follow-up period, any newly developed vertebral fractures were identified. We analyzed whether the time of occurrence differed between AVF and RVF by performing a survival analysis and each risk factor separately.Results: New vertebral fractures occurred in 47 patients (22.9%) after vertebroplasty, AVF occurred in 21 patients (10.2%), and RVF occurred in 26 patients (12.7%). The onset time of AVF was 6.2±1.8 months after vertebroplasty, showing a significant difference from that of RVF, which was 15.2±1.8 months (p<.001). In the univariate analysis, the risk factors of AVF included severe osteoporosis (T-score<-3.0), vertebroplasty in the thoracolumbar junction, sagittal imbalance, and segmental kyphosis angle >15° (p=0.029, p=0.033, p=0.001, and p=0.021, respectively). The risk factors of RVF included severe osteoporosis (T-score <-3.0) and sagittal imbalance (p=0.013 and p=0.004). In the multivariate analysis, the risk factors of AVF included vertebroplasty in the thoracolumbar junction and sagittal imbalance (hazard ratio=3.34, p=0.032 and hazard ratio=4.05, p=0.008), and those of RVF included only sagittal imbalance (hazard ratio=2.66, p=0.024).Concluson: After vertebroplasty for OVCF, a significant difference in the meantime of occurrence was found; it took 6 months for AVF and 15 months for RVF to develop. Vertebroplasty in the thoracolumbar junction was identified as a risk factor for AVF, whereas sagittal imbalance was a risk factor of both AVF and RVF. [ABSTRACT FROM AUTHOR]

Purpose: Both increased sagittal vertical axis (SVA) and sarcopenia affect performance of daily activities and morbidity in the elderly; however, little is known regarding their relationship. The aim of this study was to analyze the association between sarcopenia and increased SVA.Methods: This retrospective study included 71 female patients aged between 60 and 85 years. Entire-spine radiography was used to measure radiological parameters. A bioelectrical impedance analyzer was used to measure the skeletal muscle mass index (SMI). Gait velocity (GV) and hand grip strength (HGS) were examined as well. Lumbar spine magnetic resonance imaging was employed to measure the functional cross-sectional area (FCSA) and fat signal fraction (FSF) of the paraspinal muscle as well. The subjects were divided into two groups according to the SVA (group I; SVA > 50 mm and group II; SVA ≤ 50 mm).Results: The group I showed lower GV, HGS, and SMI than the group II (p < 0.001, < 0.001, and = 0.001, respectively). The prevalence of sarcopenia was higher in the group I (56.7%) than in the group II (17.1%) (p = 0.001). The group I also showed lower FCSA and higher FSF than the group II (p < 0.001). In multivariate analysis, the FSF (odds ratio 1.308, p = 0.004) and HGS (odds ratio 0.792, p = 0.023) were correlated with increased SVA. In addition, the BMI (odds ratio 0.756, p = 0.037), SVA (odds ratio 1.051, p = 0.031), and FCSA (odds ratio 0.995, p = 0.012) were correlated with sarcopenia.Conclusion: Sarcopenia and fatty degeneration of paraspinal muscle are closely related to increased SVA in the elderly.

Purpose: The purpose of this study was to analyse changes of spinopelvic parameters and stability in the treatment of degenerative lumbar deformity. Methods: A retrospective review was carried out on 70 cases of degenerative lumbar deformity treated by long fusion with uni-cortical S1 fixation alone (US1F group, n = 20), bi-cortical S1 fixation alone (BS1F group, n = 20), additional diagonal S2 fixation (DS2F group, n = 14), and additional iliac fixation (ILF group, n = 16) from July 2003 to April 2010. The sagittal vertical axis (SVA), lumbar lordosis (LL), sacral slope (SS), pelvic tilt (PT), pelvic incidence (PI), and stability were used to evaluate radiologic outcomes. The clinical outcome was evaluated using the Oswestry Disability Index (ODI). Results: In all groups, the LL was significantly increased at three months ( p < 0.05). The PI and the SS of ILF patients significantly increased at three months ( p < 0.05), while none of these values changed over time in non-ILF patients. The PT did not change postoperatively in any groups. The LL, SS, and PI were significantly greater in the ILF group at three months postoperatively and later ( p < 0.05). DS2F and ILF had statistically significant stability compared to US1F and BS1F ( p < 0.05). The ODI scores were significantly improved after surgery in all groups compared to before surgery ( p < 0.05). Conclusions: Patients who had ILF in long fusion for the treatment of degenerative lumbar deformity had significant restoration of spinopelvic parameters compared to the other groups. In addition, DS2F and ILF provided more stability of distal instruments. [ABSTRACT FROM AUTHOR]

This document is a letter to the editor discussing the real-world effectiveness and safety of risankizumab in adult patients with plaque psoriasis. The authors conducted a 16-week international multicenter retrospective cohort study to evaluate the outcomes of risankizumab treatment. The study included 388 patients, and after 16 weeks of treatment, 75% of patients achieved a 90% improvement in the Psoriasis Area and Severity Index (PASI90) score or a Physician Global Assessment (PGA) score of 0 or 1. Adverse events were infrequent, and treatment discontinuation events were uncommon. The study suggests that the effectiveness of risankizumab in real-world patients is comparable to the efficacy observed in phase III randomized controlled trials. However, further studies with control populations are needed to confirm these findings. [Extracted from the article]

Objectives: Acute cervical insufficiency accounts for 10-25 % of all mid-trimester pregnancy losses. However, the definition and description for the degree of acute cervical insufficiency were obscure and different among the many studies. The aim of this study was to suggest a new 4-digit quantification system and to evaluate the outcome according to the new system in women with acute cervical insufficiency.Study Design: A retrospective cohort study was conducted in patients with acute cervical insufficiency who underwent physical examination indicated cervical cerclage. Acute cervical insufficiency was defined as painless external os dilation with prolapsed and/or visible membranes on speculum examination. The status of fetal membranes was described using two values: 1) size of the prolapsed membrane (P, measured using ultrasound); and 2) size of visible fetal membranes (M, evaluated by speculum examination). The status of cervix was described using two values: 1) dilatation of the narrowest os (O, measured by ultrasound); and 2) functional cervical length (C, measured by ultrasound). The patients were divided into 3 groups as follows: Stage I, patients with visible fetal membranes (M > 0) but with a remaining functional cervix (C > 0) (N = 7); stage II, those with visible fetal membranes (M > 0) and a functional cervical length of 0 but without prolapsed membranes (P = 0) (N = 33); and stage III, those with prolapsed membranes (P > 0) (N = 40).Results: 1) Patients who delivered before 34 weeks of gestation had a significantly lower median gestational age at cerclage operation and a significantly higher median P, M, C values than those who delivered at or beyond 34 weeks of gestation(P < 0.01 for gestational age at operation, P and M values; P < 0.05 for C value); 2) The higher the stage based on PMOC quantification system, the greater the risk of preterm delivery before <24, <32, <34, and <37 weeks of gestation (P < 0.001 for all); 3) The neonatal survival rate was 100 % (7/7) for stage I, 93.9 % (31/33) for stage II, and 60 % (24/40) for stage III.Conclusion: The PMOC system was a simple method to describe the individualized conditions and to predict the risk of preterm births in all spectrums of acute cervical insufficiency.
