Project description:Background SARS-CoV-2 pandemic impact on management of liver malignancies worldwide is unknown. This study aimed to determine the impact of lockdown on patient clinical pathways and postoperative morbi-mortality. Methods This study evaluated all adults’ hospital stays for liver tumour between 2019 and 2021 from national French discharge database. Primary outcome was clinical pathway, especially surgical care and postoperative outcomes, between patients admitted during COVID-19 lockdown periods (Lockdown group) and during the same periods of 2019 and 2021 (Control groups). Results Overall population included 58508 patients: 18907 patients in the Lockdown group, 20045 in the 2019 Control group and 19556 in the 2021 Control group. Surgical activity decreased by 11.6% during Lockdowns, with 1514 (8.0%) of patients in Lockdown group treated by surgery, 1514 (8.6%) in 2019 Control group (p<0.001) and 1466 (7.4%) in 2021 Control group. Chemotherapy was more considered during the lockdown (p<0.001). More patients were operated in small-volume centers during the lockdown (34%vs.32%vs.32%, p=0.034) and less were hospitalized in highly populated regions (p<0.001). Postoperative morbidity (47%vs.47%vs.47%, p=0.90) and mortality (3.3% vs. 3.6% vs. 3.1%, p=0.80) were comparable in the three periods, with no influence of lockdowns on morbidity (RR=0.94, CI95%=0.81-1.09, p=0.40) or mortality (OR=1.12, CI95%=0.72-1.74, p=0.6). Postoperative pulmonary (17%vs.13%, p=0.024) and septic complications (20%vs.15%, p=0.022) were significantly higher during the first lockdown compared to the second. Conclusion This study provides a French overview of liver malignancies management during the COVID-19 pandemic. Surgical activity has decrease by 11.6%, moreover in the high-volume centers, with no impact on postoperative morbidity and mortality.

Project description:ObjectivesThis study aimed to explore the effects of short birth spacing (SBS), which is defined as a period of less than 33 months between two successive births, on multiple concurrent forms of child malnutrition (MCFCM) and at least one form of child malnutrition (ALOFCM) using propensity score matching (PSM).MethodsThis study used data extracted from the 2017-18 Bangladesh Demographic and Health Survey. PSM with four different distance functions, including logistic regression, classification and regression tree, single hidden layer neural network and random forest, were performed to evaluate the effects of SBS on MCFCM and ALOFCM. We also explored how the effects were modified in different subsamples, including women's empowerment, education and economic status (women's 3E index)-constructed based on women's decision-making autonomy, education level, and wealth index, and age at marriage, and place of residence.ResultsThe prevalence of SBS was 22.16% among the 4652 complete cases. The matched samples of size 2062 generated by PSM showed higher odds of MCFCM (adjusted OR (AOR)=1.25, 95% CI=1.02 to 1.56, p=0.038) and ALOFCM (AOR=1.20, 95% CI=1.01 to 1.42, p=0.045) for the SBS children compared with their counterparts. In the subsample of women with 3E index≥50% coverage, the SBS children showed higher odds of MCFCM (AOR: 1.43, 95% CI=1.03 to 2.00, p=0.041] and ALOFCM (AOR: 1.33, 95% CI=1.02 to 1.74, p=0.036). Higher odds of MCFCM (AOR=1.27, 95% CI=1.02 to 1.58, p=0.036) and ALOFCM (AOR=1.23, 95% CI=1.02 to 1.51, p=0.032) for SBS children than normal children were also evident for the subsample of mothers married at age≤18 years.ConclusionSBS was significantly associated with child malnutrition, and the effect was modified by factors such as women's autonomy and age at marriage.

Project description:BACKGROUND:The purpose of this study was to compare the efficacy and safety of two preoperative pulmonary nodule localization techniques using microcoil and hookwire. METHODS:A total of 307 patients with 324 pulmonary nodules were included in the study from March 2012 to October 2016 in two medical centers. Baseline data, positioning operation data, success rate, complications, surgery and pathological results were statistically analyzed. Complications were used as the dependent variables, whereas others were used as covariates for the propensity score matching of the two groups. Statistical analyses were performed to compare the success rate and complication rate of the matched groups. RESULTS:There were 218 lesions in the microcoil group and 106 nodules in the hookwire group. There were no significant differences in gender, age and the location of nodules between the two groups. The diameters of the nodules were smaller (8.2?±?3.5?mm vs. 10.7?±?4.3?mm) and solid nodules were fewer (11.5% vs. 26.4%) in the microcoil group. The complication rate of the two groups was not statistically significant. After propensity score matching, 71 patients in each group were successfully matched. We found that the success rate was higher (97.2% vs. 94.4%) and the incidence of complications was lower (31% vs. 15.5%) in the microcoil group. CONCLUSIONS:Both techniques have been shown to be effective in preoperative localization of tiny pulmonary nodules. The method of microcoil localization has more advantages in clinical application. KEY POINTS:Comparison of the efficacy and safety of two methods in preoperative pulmonary nodule localization in order to determine the optimal method.

Project description:The purpose of this study was to investigate the effects of preoperative oral management (POM) by dentists on the incidence of postoperative pulmonary complications (PPCs), length of hospital stay, medical costs, and days of antibiotics administration following both open and thoracoscopic esophagectomy.Dental plaque is an established risk factor for postoperative pneumonia, which could be reduced by POM. However, few clinical guidelines for cancer treatment, including those for esophageal cancer, recommend POM as routine perioperative care.We extracted data of esophagectomy cases from the Japanese Diagnosis Procedure Combination database. We subsequently conducted propensity score (PS) analyses for multilevel data, including matching, inverse probability of treatment weighting (IPTW), and standardized mortality ratio weighting (SMRW), to estimate the effect of POM by dentists on the outcomes of esophagectomy.We analyzed 3412 esophagectomy cases of which 812 were open, and 2600 were thoracoscopic surgery. In IPTW analysis to estimate the average treatment effect, the risk difference of postoperative aspiration pneumonia ranged from -2.49% to -2.02% between the POM and control groups of both open and thoracoscopic esophagectomy cases. IPTW analyses indicated that the total medical costs of thoracoscopic esophagectomy were reduced by 221,200 to 253,100 Japanese Yen (equivalent to about $2000-$2200). In PS matching and SMRW analyses to estimate average treatment effect on treated, there was no difference in outcomes between the POM and control groups.Our results suggested that in patients undergoing open or thoracoscopic esophagectomy, POM by dentists prevented the occurrence of postoperative aspiration pneumonia. It could also reduce the total medical costs of thoracoscopic esophagectomy. Thus, POM by dentists can be considered as a routine perioperative care for all patients undergoing esophagectomy, regardless of the expected risk for PPC.

Project description:Keeping in view the cascade of disturbances caused by the co-existence of multi-morbidity and depression among aged population, this study aims to ascertain the independent impact of multi-morbidity as a risk factor for the development of depressive symptoms among adults living in India. The present study utilizes data from the nationally representative survey "Longitudinal Ageing Study in India" (LASI, Wave-1, 2017-2018). The eligible sample size was 62,244 adults aged 45 years and above. Descriptive statistics along with bivariate analysis was used to understand the prevalence of depressive symptoms. Further, binary logistic regression and Propensity Score Matching (PSM) methods were applied to examine the independent effect of multi-morbidity on depressive symptoms while controlling the selected background characteristics. Overall, around one-third respondents had at least one chronic disease and one-fifth had multi-morbidity. The most prevalent chronic disease reported in the sampled population was hypertension followed by diabetes and joint disease. It is observed that older adults with multiple chronic diseases had 77% higher odds of having depressive symptoms as compared to those without a history of chronic disease in the multivariable logistic regression model. Results obtained from PSM indicate that the risk of having depressive symptoms was 3.7% higher for adults with multi- morbidity. Depressive symptom was identified to be associated with a wider range of multiple physical health problems and people with multi-morbidity are at a higher risk of having depressive symptoms. It is imperative that multi-morbidity can be used as a screener for identifying people with depressive symptoms.

Project description:BackgroundThe severity and prognosis of an array of inflammatory diseases have been predicted using systemic inflammatory indices, such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio (LMR), derived neutrophil-to-lymphocyte ratio (dNLR), and systemic immune inflammation index (SII). The purpose of this study was to examine the association between systemic inflammatory markers and postoperative arrhythmias (PA) in esophageal cancer patients.MethodsIn the study, laboratory-related parameters were gathered and examined in 278 patients (non-PA = 221, PA = 57). Fit separate propensity score matching (PSM) within subgroup strata (surgery approaches); match within strata, and aggregate for main analysis. Finally, we established a 1:1(57:57) model. The ability of inflammatory makers on the first post-esophagectomy day to distinguish PA from postoperative non-arrhythmia (non-PA) by receiver operating characteristic (ROC) analysis.ResultsOn the first post-esophagectomy day, there was a greater difference between PA and non-PA in terms of white blood cell (WBC) and neutrophil (NE), Neutrophil percentage (NE%), NLR, dNLR, LMR, and SII. After PSM, the following variables were substantially different between non-PA and PA: NE%, NLR, dNLR, and SII. It was found that WBC, NE, NE%, NLR, dNLR, LMR, and SII had the area under the curve (AUC) that was higher than 0.500 in ROC analysis, with NLR and SII having the highest AUC (AUC = 0.661). The indicators were subjected to binary logistic regression analysis, which increased the indicators' predictive ability (AUC = 0.707, sensitivity = 0.877).ConclusionOn the first post-esophagectomy day, systemic inflammatory indicators were significantly correlated with both PA and non-PA, and high SII and NLR are reliable markers of PA.

Project description:ObjectivesRecent findings suggest that the combination of mechanical bowel preparation (MBP) and preoperative oral antibiotics (OA) decreases the risk of surgical site infection (SSI) in colorectal surgery; however, this remains controversial. The present study examined the efficacy of OA plus MBP in laparoscopic colorectal cancer (CRC) surgery using propensity score matching (PSM).MethodsA total of 1080 patients with CRC underwent MBP followed by laparoscopic surgery between 2007 and 2019. OA was administered to all patients with CRC who underwent colectomy from 2018. PSM was performed to compare the effects of OA plus MBP (OA) versus MBP only (non-OA) on the rate of superficial SSI.ResultsOverall, 128 patients received OA. Significant differences were observed in age, the American Society of Anesthesiologists performance status (ASA-PS), liver disease, and preoperative serum albumin (Alb) between the OA and non-OA groups. The enrolled patients were matched using PSM into two groups based on the following factors: sex, age, body mass index, ASA-PS, diabetes mellitus, liver disease, Alb, and tumor location, which resulted in the disappearance of significant differences. A univariate analysis showed that blood loss of 100 g or more, non-OA, and preoperative chemotherapy or radiation correlated with SSI (p = 0.021, 0.010, 0.038). A multivariate analysis of these three variables identified blood loss of 100 g or more and non-OA as independent risk factors for SSI (hazard ratio (HR): 3.238, p = 0.031; HR: 2.547, p = 0.033).ConclusionsThe present study revealed that OA plus MBP markedly reduced SSI rate. OA with MBP needs to be adopted in laparoscopic CRC surgery.

Project description:Purpose: It was reported that the novel preoperative systemic immune-inflammation index (SII) can predict survival in cases of many malignant tumors. However, the prognostic significance of preoperative SII in breast cancer remains unclear. The purpose of this study was to investigate the relationship between SII and survival in breast cancer patients. Methods: Breast cancer patients (1,026) who underwent a mastectomy at Sun Yat-sen University Cancer Center were retrospectively studied. The SII was determined using the following formula: neutrophil count × platelet count/lymphocyte count. The receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value for SII. Propensity score matching (PSM) was applied to develop comparable cohorts of high SII group and low SII group. Results: A total of 1,026 patients were included as the primary cohort, and 894 patients were matched and regarded as the matched cohort. Patients were divided into two groups based on SII value: SII <601.7 and high SII >601.7. In the primary cohort, the 5-years overall survival (OS), recurrence-free survival (RFS), and distant metastasis-free survival (DMFS) rates for high SII group and low SII group were (85.6% vs. 91.3%, P = 0.016), (95.8% vs. 96.4%, P = 0.684), and (83.5% vs. 90.6%, P = 0.007), respectively. Univariate analysis showed that histological type, T stage, N stage, PR, HER2, Ki67, and SII all showed significant associations with OS; and histological type, T stage, N stage, and SII all showed significant associations with DMFS. Multivariate survival analysis revealed that SII can independently predict OS (P = 0.017) and DMFS (P = 0.007). Similar results were found in PSM cohort. Conclusions: Preoperative SII may be a reliable predictor of OS and DMFS in patients with operable breast cancer to provide personalized prognostication and assist in formulation of the clinical treatment strategy.

Project description:BackgroundBased on previous studies which failed to analyze important confounding variables, the association between preoperative anemia and outcomes of patients who underwent colorectal cancer (CRC) surgery has not been clearly demonstrated. This study aimed to investigate the relationship between preoperative anemia and short-term outcomes in patients with CRC.MethodsData from a retrospective collective database of patients who underwent CRC surgery at our hospital between September 1, 2019 and September 30, 2021 were retrieved and analyzed, and the short-term postoperative outcomes of anemic (hemoglobin < 120 g dL- 1 for female, hemoglobin < 130 g dL- 1 for male) and non-anemic patients were analyzed, using a 1:1 propensity score matching (PSM) analysis.ResultsAfter excluding some cases, the remaining 1894 patients had complete data available for analysis. The incidence of preoperative anemia was 39.8% (754/1894). Before PSM, preoperative anemia patients had a higher risk of major morbidity than non-anemia patients (27.2% vs. 23.1%, odds ratio [OR] 1.245, 95% confidence interval [CI] 1.008-1.538, P = 0.042). After PSM was performed in the cohort, 609 patients remained in the anemic and non-anemic groups. The incidence of major morbidity (25.8% vs. 24.0%, OR 1.102, 95% CI 0.849-1.429, P = 0.446) between anemic and non-anemic patients was comparable. No significant difference was found between the anemic and non-anemic groups in postoperative length of stay (8.0 [6.0-12.0] vs. 8.0 [7.0-11.0], P = 0.311). The sensitivity analysis results were in accordance with the primary outcome. Furthermore, we did not ascertain any discernible correlation between the extent of anemia and significant major morbidity.ConclusionsCompared with preoperative non-anemia, anemia status does not seem to be associated with major morbidity in patients with CRC surgery. It is noteworthy that, anemia is insufficient as a solitary risk factor and may be a better marker of poor health resulting from multiple factors.Trial registrationRegistration Authority: Chinese Clinical Trial Registry; Registration number and date: ChiCTR2100049696, 08/08/2021; Principal investigator: Ting Yan; Link to trial registry: http://www.chictr.org.cn/showproj.aspx?proj=131698 ; .

Project description:ImportanceAlthough recent guidelines recommend against performance of preoperative urine culture before nongenitourinary surgery, many clinicians still order preoperative urine cultures and prescribe antibiotics for treatment of asymptomatic bacteriuria in an effort to reduce infection risk.ObjectiveTo assess the association between preoperative urine culture testing and postoperative urinary tract infection (UTI) or surgical site infection (SSI), independent of baseline patient characteristics or type of surgery.Design, setting, and participantsThis cohort study analyzed surgical procedures performed from January 1, 2017, to December 31, 2019, at any of 112 US Department of Veterans Affairs (VA) medical centers. The cohort comprised VA enrollees who underwent major elective noncardiac, nonurological operations. Machine learning and inverse probability of treatment weighting (IPTW) were used to balance the characteristics between those who did and did not undergo a urine culture. Data analyses were performed between January 2023 and January 2024.ExposuresPerformance of urine culture within 30 days prior to surgery.Main outcomes and measuresThe 2 main outcomes were UTI and SSI occurring within 30 days after surgery. Weighted logistic regression was used to estimate odds ratios (ORs) for postoperative infection based on treatment status.ResultsA total of 250 389 VA enrollees who underwent 288 858 surgical procedures were included, with 88.9% (256 753) of surgical procedures received by males and 48.9% (141 340) received by patients 65 years or older. Baseline characteristics were well balanced among treatment groups after applying IPTW weights. Preoperative urine culture was performed for 10.5% of surgical procedures (30 384 of 288 858). The IPTW analysis found that preoperative urine culture was not associated with SSI (adjusted OR [AOR], 0.99; 95% CI, 0.90-1.10) or postoperative UTI (AOR, 1.18; 95% CI, 0.98-1.40). In analyses limited to orthopedic surgery and neurosurgery as a proxy for prosthetic implants, the adjusted risks for UTI and SSI were also not associated with preoperative urine culture performance.Conclusions and relevanceThis cohort study found no association between performance of a preoperative urine culture and lower risk of postoperative UTI or SSI. The results support the deimplementation of urine cultures and associated antibiotic treatment prior to surgery, even when using prosthetic implants.
