RESUMO
BACKGROUND: Lung adenocarcinoma is a high-mortality rate cancer. Within this category, Lung mucinous adenocarcinoma (LMAC) is a rare and distinct subtype of lung adenocarcinoma necessitating further investigation. The study was launched to compare the difference of survival features between LMAC and lung non-mucinous adenocarcinoma (LNMAC) and to investigate the significance and demand for developing a new staging system tailored to LMAC. METHODS: This retrospective study assessed the suitableness of the current staging system for LMAC. It compared the overall survival (OS) between LMAC and LNMAC from 2004 to 2020 (LNMAC: 160,387; LMAC: 6,341) and instituted a novel classification framework for LMAC based on US population. Verification group consisting of patients from two Chinese medical centers from 2010 to 2018 (n = 392) was set to ascertain the applicability of this novel system. The primary endpoint was OS. To minimize the bias, propensity score match (PSM) was employed. Survival analysis and Log-rank test were executed to explore the survival features of LMAC. RESULTS: The results indicated that the existed staging system was not suitable for LMAC. Patients diagnosed with LMAC exhibited a superior OS compared to those with LNMAC in stage IA2 (P < 0.0001), IA3 (P < 0.0001), IB (P = 0.0062), IIA (P = 0.0090), IIB (P = 0.0005). In contrast, a worse OS in stage IVA (P = 0.0103) was found in LMAC patients. The novel classification system proposed for LMAC proved to be highly applicable and demonstrated substantial efficacy, as confirmed by the verification group. CONCLUSION: The newly established classification system was more effective for LMAC, but it necessitates large-scale verification to confirm its applicability and reliability.

BACKGROUND: Acute pancreatitis is easily confused with abdominal pain symptoms, and it could lead to serious complications for pregnant women and fetus, the mortality was as high as 3.3% and 11.6-18.7%, respectively. However, there is still lack of sensitive laboratory markers for early diagnosis of APIP and authoritative guidelines to guide treatment. OBJECTIVE: The purpose of this study was to explore the risk factors of acute pancreatitis in pregnancy, establish, and evaluate the dynamic prediction model of risk factors in acute pancreatitis in pregnancy patients. STUDY DESIGN: Clinical data of APIP patients and non-pregnant acute pancreases patients who underwent regular antenatal check-ups during the same period were collected. The dataset after propensity matching was randomly divided into training set and verification set at a ratio of 7:3. The model was constructed using Logistic regression, least absolute shrinkage and selection operator regression, R language and other methods. The training set model was used to construct the diagnostic nomogram model and the validation set was used to validate the model. Finally, the accuracy and clinical practicability of the model were evaluated. RESULTS: A total of 111 APIP were included. In all APIP patients, hyperlipidemic pancreatitis was the most important reason. The levels of serum amylase, creatinine, albumin, triglyceride, high-density lipoprotein cholesterol, and apolipoprotein A1 were significantly different between the two groups. The propensity matching method was used to match pregnant pancreatitis patients and pregnant non-pancreatic patients 1:1 according to age and gestational age, and the matching tolerance was 0.02. The multivariate logistic regression analysis of training set showed that diabetes, triglyceride, Body Mass Index, white blood cell, and C-reactive protein were identified and entered the dynamic nomogram. The area under the ROC curve of the training set was 0.942 and in validation set was 0.842. The calibration curve showed good predictive in training set, and the calibration performance in the validation set was acceptable. The calibration curve showed the consistency between the nomogram model and the actual probability. CONCLUSION: The dynamic nomogram model we constructed to predict the risk factors of acute pancreatitis in pregnancy has high accuracy, discrimination, and clinical practicability.

BACKGROUND: Setting positive end-expiratory pressure (PEEP) at around 5 cm H2O in the early postoperative period seems a common practice for most patients. It remains unclear if the routine application of higher levels of PEEP confers any meaningful clinical benefit for cardiac surgical patients. The aim of this study was to compare moderate versus conventional lower PEEP on patient-centered outcomes in the intensive care unit (ICU). METHODS: This is a single-center retrospective study involving patients receiving cardiac surgery from June 2022 to May 2023. Propensity-score matching (PSM) was used to balance the baseline differences. Primary outcomes were the duration of mechanical ventilation and ICU length of stay. Secondary outcomes included PaO2/FiO2 ratio at 24 h and the need for prone positioning during ICU stay. RESULTS: A total of 334 patients were included in the study, 102 (31%) of them received moderate PEEP (≥ 7 cm H2O) for the major time in the early postoperative period (12 h). After PSM, 79 pairs of patients were matched with balanced baseline data. The results showed that there was marginal difference in the distribution of mechanical ventilation duration (p = 0.05) and the Moderate PEEP group had a higher extubation rate at the day of T-piece trial (65 [82.3%] vs 52 [65.8%], p = 0.029). Applying moderate PEEP was also associated with better oxygenation. No differences were found regarding ICU length of stay and patients requiring prone positioning between groups. CONCLUSION: In selective cardiac surgical patients, using moderate PEEP compared with conventional lower PEEP in the early postoperative period correlated to better oxygenation, which may have potential for earlier liberation of mechanical ventilation.

BACKGROUND: Based on the molecular expression of cancer cells, molecular subtypes of breast cancer have been applied to classify patients for predicting clinical outcomes and prognosis. However, further evidence is needed regarding the influence of molecular subtypes on the efficacy of radiotherapy (RT) after breast-conserving surgery (BCS), particularly in a population-based context. Hence, the present study employed a propensity-score-matched cohort design to investigate the potential role of molecular subtypes in stratifying patient outcomes for post-BCS RT and to identify the specific clinical benefits that may emerge. METHODS: From 2006 to 2019, the present study included 59,502 breast cancer patients who underwent BCS from the Taiwan National Health Insurance Research Database. Propensity scores were utilized to match confounding variables between patients with and without RT within each subtype of breast cancer, namely luminal A, luminal B/HER2-negative, luminal B/HER2-positive, basal-like, and HER2-enriched ones. Several clinical outcomes were assessed, in terms of local recurrence (LR), regional recurrence (RR), distant metastasis (DM), disease-free survival (DFS), and overall survival (OS). RESULTS: After post-BCS RT, patients with luminal A and luminal B/HER2-positive breast cancers exhibited a decrease in LR (adjusted hazard ratio [aHR] = 0.18, p < 0.0001; and, 0.24, p = 0.0049, respectively). Furthermore, reduced RR and improved DFS were observed in patients with luminal A (aHR = 0.15, p = 0.0004; and 0.29, p < 0.0001), luminal B/HER2-negative (aHR = 0.06, p = 0.0093; and, 0.46, p = 0.028), and luminal B/HER2-positive (aHR = 0.14, p = 0.01; and, 0.38, p < 0.0001) breast cancers. Notably, OS benefits were found in patients with luminal A (aHR = 0.62, p = 0.002), luminal B/HER2-negative (aHR = 0.30, p < 0.0001), basal-like (aHR = 0.40, p < 0.0001), and HER2-enriched (aHR = 0.50, p = 0.03), but not luminal B/HER2-positive diseases. Remarkably, when considering DM, luminal A patients who received RT demonstrated a lower cumulative incidence of DM than those without RT (p = 0.02). CONCLUSION: In patients with luminal A breast cancer who undergo BCS, RT could decrease the likelihood of tumor metastasis. After RT, the tumor's hormone receptor status may predict tumor control regarding LR, RR, and DFS. Besides, the HER2 status of luminal breast cancer patients may serve as an additional predictor of OS after post-BCS RT. However, further prospective studies are required to validate these findings.

OBJECTIVE: Dual antiplatelet therapy (DAPT) continues to be the preferred medication regimen after the placement of a carotid stent using the transcarotid revascularization (TCAR) technique despite a dearth of quality data. Therefore, this investigation was performed to define the risks associated with antiplatelet choice. METHODS: We queried all patients who underwent TCAR captured by the Vascular Quality Initiative from September 2016 to June 2022, to determine the association between antiplatelet choice and outcomes. Patients maintained on DAPT were compared with those receiving alternative regimens consisting of single antiplatelet, anticoagulation, or a combination of the two. A 1:1 propensity-score match was performed with respect to baseline comorbidities, functional status, anatomic/physiologic risk, medications, and intraoperative characteristics. In-hospital and 1-year outcomes were compared between the groups. RESULTS: During the study period, 29,802 procedures were included in our study population, with 24,651 (82.7%) receiving DAPT and 5151 (17.3%) receiving an alternative antiplatelet regimen. A propensity-score match with respect to 29 variables generated 4876 unique pairs. Compared with patients on DAPT, in-hospital ipsilateral stroke was significantly higher in patients receiving alternative antiplatelet regimens (1.7% vs 1.1%, odds ratio [95% confidence interval]: 1.54 [1.10-2.16], P = .01), whereas no statistically significant difference was noted with respect to mortality (0.6% vs 0.5%, 1.35 [0.72-2.54], P = .35). A composite of stroke/death was also more likely in patients receiving an alternative regimen (2.4% vs 1.7%, 1.47 [1.12-1.93], P = .01). Immediate stent thrombosis (2.75 [1.16-6.51]) and a nonsignificant trend toward increased return to the operating room were more common in the alternative patients. Conversely, the incidence of perioperative myocardial infarction was lower in the alternative regimen group (0.4% vs 0.7%, 0.53 [0.31-0.90], P = .02). At 1 year after the procedure, we observed an increased risk of mortality (hazard ratio [95% confidence interval]: 1.34 [1.11-1.63], P < .01) but not stroke (0.52 [0.27-0.99], P = .06) in patients treated with an alternative medication regimen. CONCLUSIONS: This propensity-score-matched analysis demonstrates an increased risk of in-hospital stroke and 1-year mortality after TCAR in patients treated with an alternative medication regimen instead of DAPT. Further studies are needed to elucidate the drivers of DAPT failure in patients undergoing TCAR to improve outcomes for carotid stenting patients.

BACKGROUND: Single-incision plus one-port laparoscopic surgery (SILS + 1) has been demonstrated to be minimally invasive while possessing better cosmesis and less pain compared with conventional laparoscopic surgery (CLS). However, SILS + 1 as an alternative to CLS for colorectal cancer is still controversial. METHODS: A total of 1071 patients who underwent curative laparoscopic surgery for colon cancer between 2015 and 2018 were included. Of these patients, 258 SILS + 1 cases and 516 CLS cases were analyzed using propensity score matching. The baseline characteristics, surgical outcomes, pathologic findings and recovery course, morbidity and mortality within postoperative 30 days and 3-year disease-free and overall survival were compared. RESULTS: Baseline characteristics were balanced between the groups. The mean operating time was significantly shorter in SILS + 1 group, with less estimated blood loss. Tumor size, tumor differentiation, number of harvested lymph nodes, resection margin and pathologic T, N, TNM stage was similar between the groups. There was no significant difference in overall perioperative complications. Uni- and multivariate analyses revealed that SILS + 1 was not a risk factor for complications. Postoperatively, SILS + 1 group showed faster recovery than CLS group in terms of ambulation, bowel function, oral intake and discharge. The 3-year disease-free survival rates of SILS + 1 and CLS groups were 90.1% and 87.3%(p = 0.59), respectively and the 3-year overall survival rates were 93.3% vs. 89.8%(p = 0.172). DISCUSSION: Our study revealed that SILS + 1 is safe, feasible, oncologically efficient, and may be considered as a surgical option for selected patients with colorectal cancer.

BACKGROUND: Invasive candidiasis is the most common hospital-acquired fungal infection in intensive care units (ICU). The Geriatric Nutritional Risk Index (GNRI) score was developed to evaluate the nutritional status of elderly adults. We aimed to assess the association between the GNRI score and the risk of invasive candidiasis in elderly patients admitted to ICU. METHODS: Hospitalization information of elderly patients with invasive candidiasis was collected retrospectively from Medical Information Mart for Intensive Care (MIMIC) IV and MIMIC-III Clinical Database CareVue subset from 2001 to 2019. The main outcome of this study was the diagnosis of invasive candidiasis in patients. We employed a multivariable Cox regression and propensity score matching to balance the influence of confounding factors on the outcome. Furthermore, we conducted sensitivity analyses by categorizing the GNRI into classes based on thresholds of 98, 92, and 81. RESULTS: A total of 6739 patients were included in the study, among whom 134 individuals (2%) were diagnosed with invasive candidiasis. The GNRI scores of patients with invasive candidiasis upon admission to the ICU were significantly lower, measuring 88.67 [79.26-98.27], compared to the control group with a score of 99.36 [87.98-110.45] (P < 0.001). The results of the multivariable Cox regression analysis demonstrated a strong association between higher GNRI scores and a decreased risk of invasive candidiasis infection (HR: 0.98, 95% CI: 0.97-0.99, P = 0.002). Consistently, similar results were obtained when analyzing the propensity score-matched cohort (HR: 0.99, 95% CI: 0.98-1, P = 0.028). Sensitivity analyses further confirmed a significantly increased risk of invasive candidiasis infection with lower GNRI scores. Specifically, the following associations were observed: GNRI ≤ 98 (HR: 1.83, 95% CI: 1.23-2.72, P = 0.003), GNRI ≤ 92 (HR: 1.68, 95% CI: 1.17-2.4, P = 0.005), 82 ≤ GNRI ≤ 92 (HR: 1.63, 95% CI: 1.01-2.64, P = 0.046), GNRI ≤ 81 (HR: 2.31, 95% CI: 1.44-3.69, P < 0.001). CONCLUSIONS: Lower GNRI score was significantly associated with an increased risk of invasive candidiasis in elderly patients in ICU. Further research is needed to validate whether improving nutrition can prevent invasive candidiasis.

BACKGROUND: Minimally invasive liver resection of the posterosuperior region is considered a challenging procedure due to poor exposure and difficult bleeding control. A robotic approach is supposed to be advantageous in posterosuperior segmentectomy. Its benefits over laparoscopic liver resection (LLR) remain undetermined. This study compared robotic liver resection (RLR) and LLR in the posterosuperior region performed by a single surgeon. MATERIALS AND METHODS: We retrospectively analyzed consecutive RLR and LLR performed by a single surgeon between December 2020 and March 2022. Patient characteristics and perioperative variables were compared. A 1:1 propensity score matched (PSM) analysis was performed between both groups. RESULTS: The analysis included 48 RLR and 57 LLR procedures in the posterosuperior region. After PSM analysis, 41 cases of both groups were retained. In pre-PSM cohort, the operative time in the RLR group was significantly shorter than in the LLR group (160 vs. 208 min, P = 0.001), especially in radical resection of malignant tumors (176 vs. 231 min, P = 0.004). The total Pringle maneuver duration was also markedly shorter (40 vs. 51 min, P = 0.047), and the estimated blood loss in the RLR group was lower (92 vs. 150 mL, P = 0.005). The postoperative hospital stay (POHS) in the RLR group was significantly shorter (5.4 vs. 7.5 days, P = 0.048). In PSM cohort, operative time in the RLR group was also significantly shorter (163 vs. 193 min, P = 0.036), and the estimated blood loss was lower (92 vs. 144 mL, P = 0.024). However, the total Pringle maneuver duration and POHS showed no significant difference. The complications were similar between two groups in both pre-PSM and PSM cohorts. CONCLUSION: RLR in the posterosuperior region was as safe and feasible as LLR. RLR was associated with reduced operative time and blood loss than LLR.

BACKGROUND: To assess the prevalence, risk factors, clinical characteristics of Acute fatty liver of pregnancy (AFLP) patients, and outcomes of AFLP patients treated with plasma exchange (PE). METHODS: We retrospectively reviewed the AFLP patients admitted to the First Affiliated Hospital of Xi'an Jiaotong University and Xijing Hospital of Air Force Medical University from January 2012 to May 2022. Final prediction model for death among AFLP by means of stepwise backward elimination with p value < 0.05. Patients treated with and without PE were compared by propensity-matched cohort study. RESULTS: Two hundred ninety eight patients with the diagnosis of AFLP, and finally 290 patients were enrolled in the cohort study, 50 of whom (17.2%) were dead. Compared with AFLP patients alive, the dead of patients were more likely to be combined encephalopathy (p < 0.01), postpartum hemorrhage (p < 0.01), and found significantly higher frequency of fetal distress (p = 0.04), fetal death (p < 0.01). we developed a predicted probability value and with an area under the receiver operating characteristics (ROC) curve of 0.94 (95%CI 0.87 to 1.00), indicating AFLP patients' death. The patients treated with PE had a significantly lower 60-day mortality rate (OR 0.42, 95% CI 0.29 to 2.64, p = 0.04), and significantly shorter duration of hospital-free days at day 28 (p = 0.01). CONCLUSIONS: In conclusion, our study indicated that liver function were risk factors for maternal mortality, and PE was a protective factor for maternal 60-day mortality and hospital-free days at day 28 in AFLP patients.

BACKGROUND: Both video-assisted thoracoscopic surgery (VATS) thymectomy and robot-assisted thoracoscopic surgery (RATS) thymectomy have been suggested as technically sound approaches for early-stage thymic epithelial tumors. However, the choice of VATS or RATS thymectomy for large and advanced thymic epithelial tumors remains controversial. In this study, the perioperative outcomes of VATS and RATS thymectomy were compared in patients with large thymic epithelial tumors (size ≥5.0 cm). METHODS: A total of 113 patients with large thymic epithelial tumors who underwent minimally invasive surgery were included. Sixty-three patients underwent RATS, and 50 patients underwent VATS. Patient characteristics and perioperative variables were compared. RESULTS: Compared with the VATS group, the RATS group experienced a shorter operation time (median: 110 min vs.130 min; P < 0.001) and less blood loss (30.00 ml vs. 100.00 ml, P < 0.001). No patients in the RATS group needed conversion to open surgery, but in the VATS series, five patients required conversion to open procedures (0% vs. 14.29%, P = 0.054). The rate of concomitant resection in the RATS group was similar to that in the VATS group (11.43% vs. 5.71%; P = 0.673). There was no significant difference between the two groups in the duration of chest tube (P = 0.587), postoperative complications (P = 1.000), and the duration of postoperative hospital stay (P = 0.141). CONCLUSION: For large thymic epithelial tumors, RATS thymectomy can be performed safely and effectively in a radical fashion. Due to the advanced optics and precise instrument control, concomitant resections can be easily achieved in larger thymic epithelial tumors using the robotic approach.

BACKGROUND: Gastric cancer is a major public health problem around the globe. With the standardization of tumor treatment, surgery continues to be the most important treatment method for gastric cancer. However, changes in body composition and nutrition index parameters in patients with Billroth II and Roux-en-Y anastomosis following totally laparoscopic distal gastrectomy (TLDG) remain unclear. METHODS: This was a single-center retrospective study. A total of 369 patients who underwent TLDG at the First Affiliated Hospital of Soochow University (Suzhou, China) between January 2016 and February 2019 were included and assigned to the Billroth II group or Roux-en-Y group according to the anastomosis method. After propensity score matching, body composition and relevant clinical data were compared between the two groups. RESULTS: The operation time for the Billroth II group was significantly shorter than for the Roux-en-Y group (174.12 ± 39.33 min vs. 229.19 ± 28.12 min, P < 0.001). In addition, the Billroth II group showed lower skeletal muscle loss. Specifically, the Billroth II group showed a - 4.77 ± 4.88% change in the skeletal muscle index (SMI), whereas the Roux-en-Y group showed a - 11.89 ± 8.68% change (P = 0.001). The Billroth II group also showed a smaller decrease in BMI than the Roux-en-Y group (- 6.67 ± 7.76% vs. - 13.12 ± 10.79%, P = 0.018). CONCLUSIONS: These results suggest that Billroth II anastomosis after TLDG has advantages over Roux-en-Y for maintaining patient body composition, especially in terms of SMI, and may serve as a useful reference when choosing an anastomosis method.

BACKGROUND AND OBJECTIVES: The treatment paradigm for advanced hypopharyngeal cancer has shifted from surgical approaches to organ preservation. However, recent studies indicated that surgical approaches may be associated with better survival rates. This study aimed to conduct a head-to-head comparison of survival outcomes and complications with surgical versus nonsurgical approaches using a nationwide database. METHODS: Using a nationwide data set, we gathered 2196 propensity score-matched patients with stage III/IVa hypopharyngeal cancer. We compared survival rates and complications among patients with surgical and nonsurgical cancer treatment. RESULTS: Patients with stage III and IVa hypopharyngeal cancer who underwent initial surgery had significantly better 5-year overall survival and disease-free survival rates compared to their nonsurgical counterparts. There were no significant differences in long-term complications with regard to swallowing. CONCLUSIONS: These results suggest that patients who underwent initial surgery for advanced hypopharyngeal cancers had better survival rates and equivalent long-term function.

BACKGROUND: Major depressive disorder (MDD) with comorbid borderline personality disorder (BPD) makes the clinical symptoms of patients more complex and more difficult to treat, so more attention should be paid to the recognition of their clinical features. This study investigated the differences between patients with MDD with and without BPD in clinical traits. METHODS: Propensity score matching was used to analyze the retrospective patients' data from August 2012 to September 2019. Altogether, 1381 patients with MDD were enrolled; 38 patients with MDD were matched to compare demographic data, and scores on the Hamilton Depression Scale, Hamilton Anxiety Scale (HAMA), Self-Rating Depression Scale (SDS), Modified Overt Aggression Scale (MOAS), and the frequency of nonsuicidal self-harm (NSSH). RESULTS: Compared to patients with MDD without BPD, the age of onset of patients with MDD with comorbid BPD was significantly earlier (t = 3.25, p = .00). The scores of HAMA (t = -2.28, p = .03), SDS (t = 9.31, p = .00), MOAS (t = -13.67, p = .00), verbal aggression (t = -3.79, p = .00), aggression against objects (t = -2.84, p = .00), aggression against others (t = -6.70, p = .00), and aggression against self (t = -9.22, p = .00) were significantly higher in patients with MDD with comorbid BPD. Moreover, the frequency of NHSS in these patients was significantly higher (χ2 = 20.13, p = .00). MOAS was an independent influencing factor in these (odds ratio = 7.38, p = .00). CONCLUSIONS: Patients with BPD showed early onset and increased complaints relative to symptoms, accompanied by obvious anxiety symptoms, impulsive behavior, and NSSH. Therefore, patients with MDD with impulsive behavior have comorbid BPD.

BACKGROUND: To assess the prevalence, risk factors, clinical characteristics, and outcomes of acute pancreatitis (AP) in patients with hemorrhagic fever with renal syndrome (HFRS). METHODS: All patients diagnosed with HFRS admitted to the First Affiliated Hospital of Xi'an Jiaotong University from January 2013 to July 2020 were enrolled. Patients with and without AP were compared by two risk stratification models: (1) a multivariate regression analysis using propensity score to adjust for confounding and (2) a propensity-matched nested case-control study. RESULTS: A total of 346 patients were enrolled in the cohort study, 29 of whom (8.4%) were diagnosed as AP. There was no significant difference between patients with and without AP with regards to common risk factors and presenting signs/symptoms other than gastrointestinal symptoms (p < 0.01). The patients with AP had a significantly higher 90-day mortality rate (24.1% vs. 3.5%, OR 8.9, 95% CI 1.3 to 103.4, p = 0.045), and significantly shorter duration of therapy free-days to 28 day such as RRT and mechanical ventilation free days (p < 0.05, respectively). CONCLUSIONS: Our study indicated that AP was independently associated with higher mortality in HFRS patients. While considering the difficulty of early recognition of AP among HFRS patients with similar signs and/or symptoms, further laboratory and imaging studies might help identify these patients at risk of poor clinical prognosis.

BACKGROUND: Chylothorax remains a challenging and potentially life-threatening postoperative complication after minimally invasive esophagectomy (MIE). The effect of intraoperative prophylactic thoracic duct ligation on preventing postoperative chylothorax still remains controversial. Moreover, the potential impact of thoracic duct ligation on long-term outcome after MIE has not been well established. METHODS: From September 2009 to July 2018, a total of 600 consecutive patients suffering from thoracic esophageal cancer who underwent thoracoscopic-laparoscopic McKeown esophagectomy in the Department of Thoracic surgery at Daping hospital were eligible. Among them, 559 patients received esophagectomy with preventive thoracic duct ligation and 41 patients did not. Propensity score matching (PSM) was performed to improve comparability between the two groups. Log-rank test was used to assess the survival differences between groups. RESULTS: Postoperative chylothorax occurred in five patients in the preservation group (PG) and in seven patients in the ligation group (LG) (12.2% vs. 1.3%, P = 0.001). The median age of the patients in the preservation group (PG) was 57.78 (range, 37-76) years, while the median age in the ligation group (LG) was 62.75 (range, 39-87) years. The PG had more patients with tumor located in middle thoracic esophagus and stage T3 than LG, 82.9% vs. 55.6%, 70.7% vs. 45.6%, respectively. After PSM (40 matched patients in PG and 134 in LG), there was no significant between-group difference with respect to age, tumor location, and T stage. The median survival times for patients in the PG and LG were 69.5 months (95% interval confidence, CI 54.6-84.3) and 65.2 months (95% CI 56.3-74.1), respectively (P = 0.977). The 5-year survival rates were comparable between PG and LG (54.9% vs. 54.4%, P = 0.977). CONCLUSION: On the basis of the present results, routine thoracic duct ligation during minimally invasive McKeown esophagectomy for cancer is an effective and safe method for prevention of postoperative chylothorax, and does not exert unfavourable effect on long-term survival.

BACKGROUND: Component Separation (CST) typically involves incision of one or more fascial planes to generate myofascial advancement flaps to assist with fascial closure in ventral hernia repair (VHR). The aim of this study was to compare peri-operative outcomes and quality of life (QOL) after CST versus patients without CST (No-CST) in large, preperitoneal VHR (PPVHR). METHODS: A prospective, single institution hernia study examined all patients undergoing PPVHR with synthetic mesh. Emergency and contaminated operations were excluded. A case-control cohort was identified using propensity score matching for CST and No-CST. QOL was assessed using the Carolinas Comfort Scale. RESULTS: The algorithm matched 113 CST cases to 113 No-CST cases. The groups (CST vs No-CST) were similar regarding age, BMI, diabetes, smoking, defect size, mesh size, and follow-up. In univariate analysis, there was no difference in recurrence between the CST and no-CST groups (0.9% vs 0.9%, p = 1.0) or mesh infection (0.9% vs 0.0%, p = 1.0). CST did have more wound complications (29.2% vs 16.1%, p = 0.019). When controlling for panniculectomy and diabetes with multivariate logistic regression, CST continued to have had an increased risk for wound complications (OR 2.27, CI 1.16-4.47). QOL was routinely assessed. The groups were similar pre-operatively with 76.3% of CST patients and 77.8% of No-CST patients having pain (p = 1.0). At 1, 6, 12, 24, and 36 months post-operatively, the groups had equal QOL. CONCLUSION: The use of CST versus No-CST in the repair of large VHs results in an increased risk of wound complications but does not increase the hernia recurrence rate. In the largest QOL comparative study to date, CST's generation of myofascial advancement flaps does not negatively impact patient QOL in the repair of large ventral hernias in the short or long term.

AIMS: To investigate workplace violence and nurse outcomes by comparing gender differences. DESIGN: A secondary analysis of cross-sectional survey data. METHODS: Workplace violence was measured by four items from the International Hospital Outcome Study. Nurse outcomes were measured by tools including burnout, job satisfaction and intention to stay. We used propensity score matching to generate a sociodemographic balanced dataset of 108 male and 288 female nurses. A hypothetical relationship model was derived from the affective events theory. Comparative statistics and multi-group structural equation modelling were conducted to analyze gender differences. Data were collected in China from December 2013 - August 2014. RESULTS: Male nurses reported more workplace violence from staff and less intention to stay than females. Besides finding the mediation of burnout sharing with female nurses consistent with the affective events theory, workplace violence was directly linked to less intention to stay in male nurses. CONCLUSION: Male nurses experience more workplace violence by staff than female nurses. Besides responding emotionally to workplace violence like female nurses, male nurses also respond behaviourally. IMPACT: What problem did the study address? Gender differences in workplace violence and its relationship to nurse outcomes. What were the main findings? Male nurses experienced more workplace violence than female nurses, linked directly to less intention to stay. Workplace violence linked to less job satisfaction and intention to stay in nurses was mediated by burnout. Where and on whom will the research have impact? Gender-based prevention of and coping with workplace violence should be included in nursing training.

BACKGROUND: The well-documented benefits of physical activity (PA) are still poorly characterized in long-term kidney transplant outcome. This study analyzed the impact over a 10-year follow-up of PA on graft function in Italian kidney transplant recipients (KTRs). METHODS: Since 2002, the Italian Transplant-Information-System collected donor and recipient baseline and transplant-related parameters in KTRs. In 2015, 'penchant for PA' (PA ≥ 30-min, 5 times/week) was added. Stable patients aged ≥18 years at the time of first-transplantation were eligible. KTRs with at least 10-year follow-up were also analyzed. Mixed-effect regression models were used to compare eGFR changes over time in active versus non-active patients. RESULTS: PA information was available for 6,055 KTRs (active 51.6%, non-active 48.4%). Lower penchant for PA was found in overweight and obese patients (OR = 0.84; OR = 0.48, respectively), in those with longer dialysis vintage (OR = 0.98 every year of dialysis), and older age at transplant. Male subjects showed greater penchant for PA (OR = 1.25). A slower decline of eGFR over time was observed in active KTRs compared to non-active, and this finding was confirmed in the subgroup with at least 10-year follow-up (n = 2,060). After applying the propensity score matching to reduce confounding factors, mixed-effect regression models corroborated such better long-term trend of graft function preservation in active KTRs. CONCLUSIONS: Penchant for PA is more frequent among male and younger KTRs. Moreover, in our group of Italian KTRs, active patients revealed higher eGFR values and preserved kidney function over time, up to 10-years of follow-up.

BACKGROUND: Lobectomy is the standard treatment for patients with stage I non-small cell lung cancer (NSCLC). Recent studies have shown promising results of stereotactic body radiation therapy (SBRT) in these patients. We retrospectively compared the outcomes of lobectomy and SBRT in these patients from our therapeutic center. METHODS: Patients who underwent lobectomy or SBRT for clinical T1-2a (T size≤5 cm), N0 M0, NSCLC between December 2011 and August 2016 were reviewed. Patient characteristics, treatment-related outcomes and toxicities were analyzed. Propensity score matching (PSM) was performed to improve comparability between the two groups. RESULTS: Median follow-up period in the lobectomy (n = 246) and SBRT (n = 70) group was 31.4 months and 24.9 months, respectively. Three-year local recurrence-free survival (LRFS) was comparable in the two groups (97% vs. 91.7%, respectively; P = 0.768). Recurrence-free survival (RFS) at 3-year in the lobectomy and SBRT groups was 85.4 and 69.5%, respectively (P = 0.014). Three-year overall survival (OS) after lobectomy and SBRT was 88.2 and 79.7%, respectively (P = 0.027), while 3-year cancer-specific survival (CSS) was 91.3 and 82.5% (P = 0.022). After PSM (45 matched patients in each group), there was no significant between-group difference with respect to 3-year LRFS (89.6% vs. 87.5%, P = 0.635), RFS (77.6% vs. 67.3%, P = 0.446), OS (78.5% vs. 79.5%, P = 0.915) or CSS (86.4 and 79.5%, P = 0.551). In matched subgroup, 30-day mortality after lobectomy was 2.2%, and no treatment-related death occurred after SBRT. CONCLUSIONS: Treatment-related outcomes of SBRT and lobectomy were comparable. SBRT was well tolerated and had a very low toxicity profile in our study. SBRT is a promising alternative treatment option for stage I NSCLC patients. This study indicates that matching these disparate cohorts of patients is challenging. Clinical trials are essential to define the indications and relative efficacy of lobectomy and SBRT in a selected population.

BACKGROUND: The aims of this study were to (1) describe a novel technique for appropriate treatment of bone defects in medial tibial plateau grafted with autologous resected bone and (2) compare clinical outcomes, radiographic results, and survivorship of these knees with those of standard total knee arthroplasty (TKA) without bone defect. METHODS: We retrospectively reviewed 50 cases of primary TKA involving bone defects of medial tibial plateau managed with bone grafting for a minimum follow-up of 7 years. Autologous resected bones were used for bone graft after removing solid cortical bones at the defect site. After bone graft group was completed, one-to-one patient-matched control was accomplished based on propensity score matching of 50 knees. Survivorship was analyzed using the Kaplan-Meier method. The endpoint of survival was revision of implant. Clinical outcomes were also assessed including Knee Society Score and Western Ontario and McMaster Universities Osteoarthritis Index score. RESULTS: The mean follow-up was 117 months in the group with bone graft and 108 months in the group without bone graft. There were no significant differences in postoperative clinical scores and knee alignment. Nonprogressive radiolucent lines measuring <2 mm were observed in 8 knees in the group with bone graft and 9 knees in the group without bone graft. During the follow-up period, 1 patient with late infection underwent 2-stage revision and another revision for tibial loosening occurred in both groups. The 10-year cumulative survival rate for revision was 96.0% in both groups. CONCLUSION: Our technique of management of medial tibial bone defect using autologous bone graft yielded desirable results based on survival rate and clinical outcome.
