Background. Based on a pilot study with 34 patients, applying the modified sequential organ failure assessment (SOFA) score intraoperatively could predict a prolonged ICU stay, albeit with only 4 risk factors. Our objective was to develop a practicable intraoperative model for predicting prolonged ICU stay which included more relevant risk factors.Methods. An extensive literature review identified 6 other intraoperative risk factors affecting prolonged ICU stay. Another 168 patients were then recruited for whom all 10 risk factors were extracted and analyzed by logistic regression to form the new prognostic model.Results. The multivariate logistic regression analysis retained only 6 significant risk factors in the model: age ≥ 60 years, PaO2/FiO2ratio ≤ 200 mmHg, platelet count ≤ 120,000/mm3, requirement for inotrope/vasopressor ≥ 2 drugs, serum potassium ≤ 3.2 mEq/L, and atrial fibrillation grading ≥2. This model was then simplified into the Open-Heart Intraoperative Risk (OHIR) score, comprising the same 6 risk factors for a total score of 7—a score of ≥3 indicating a likely prolonged ICU stay (AUC for ROC of 0.746).Conclusions. We developed a new, easy to calculate OHIR scoring system for predicting prolonged ICU stay as early as 3 hours after CPB. It comprises 6 risk factors, 5 of which can be manipulated intraoperatively.

Pneumonia is one of the leading causes of morbidity and mortality in under fives throughout the world, particularly in developing countries. A case control study was carried out in Bangabandhu Memorial Hospital, University of Science and Technology during the period of January to July 2006. 192 hospitalized infants of 2–12 months age group with World Health Organization(WHO) defined severe pneumonia with radiological confirmation were enrolled in the study, while controls were normal infant of same age group attending EPI center for vaccination. The children were managed using a standard protocol, factors were examined by univariate logistic regression analyasis. The factors whose odds ratio were significantly below 25% and considered as medically important were included in multivariate logistic regression analysis. Out of 192 children, 136(70.8%) were male, 56(29.2%) were female, 2-6 months old infants were 120(62.5%), >6 -12 months infants were 72(37.5%), malnutrition were present in 155( 80.72%), 145(75.5%) lived in slum area, 66(33.7%) were treated by quack, 63% were completely immunized and 3(10.5%) died. On multivariate analysis the following risk factors were found significant i.e. malnutrition, indoor smoke resulting from burning wood and manure used as fuel, non immunization, poor economy , poor housing. Significant risk factors for mortality in severe pneumonia are associated with 3rd degree malnutrition and congenital abnormality of heart with Downs syndrome. Malnutrition, indoor smoke, non-immunization, poor economy, poor housing, and smoking in bed room are important risk factors associated significantly with severe pneumonia and fatal outcome was associated with 3rd degree malnutrition.

BackgroundLugol chromoendoscopy (LCE) is a technique that is inexpensive and convenient for screening esophageal neoplastic lesions. However, the specificity of LCE is limited. The purpose of this study was to determine the risk characteristics of lesions related to false-positive results for LCE.MethodsIn this retrospective study, 871 lesions in 773 patients scheduled for LCE in Wuhan Union Hospital and First Affiliated Hospital of Shihezi University between April 2013 and October 2018 were enrolled. The 871 lesions were used to determine the diagnostic performance of LCE for detecting esophageal neoplastic lesions and were divided into an LCE-positive group (627 lesions) and an LCE-negative group (244 lesions). Six hundred and twenty-seven unstained/understained lesions from 563 patients were used to determine the significant risk factors for misdiagnosis of neoplasms by LCE. Among them, 358 lesions and 269 lesions were classified into the misdiagnosed group and correctly diagnosed group, respectively. A multivariate logistic regression analysis was conducted for suspected esophageal neoplastic lesions during the LCE examination.ResultsThe sensitivity, specificity, and overall accuracy for LCE were 100%, 40.5%, and 58.9%, respectively. Among 13 characteristics of lesions, lesions with branching vascular network (OR 4.53, 95% CI 2.23–9.21, p < 0.001), smooth lesions (OR 2.40, 95% CI 1.38–4.18, p = 0.002) under white light endoscopy (WLE), lesions with a size < 5 mm (OR 3.06, 95% CI 1.38–6.78, p = 0.006), ill-demarcated lesions (OR 7.83, 95% CI 4.59–13.37, p < 0.001), and pink color sign (PCS)-negative (OR 4.04, 95% CI 2.38–6.84, p < 0.001) lesions after reaction with iodine solution were independent risk factors for misdiagnosis as neoplastic lesions by LCE.ConclusionLCE has a high sensitivity but limited specificity for screening esophageal neoplastic lesions. For unstained or understained lesions, branching vascular network or smooth appearance under WLE, a size < 5 mm in diameter, ill-demarcated, or PCS-negative lesions after staining are related to the misdiagnosis of esophageal neoplastic lesions by LCE based on logistic regression. The multivariate logistic model may be used to predict the possibility of misdiagnosis and help improve the specificity of LCE in diagnosing esophageal neoplastic lesions.

Abstract Background: Progressive spinal deformity has become a well-recognized complication of intracanal tumors resection. However, the factors affecting post-operative spinal stability remain to be further research. Here, we described the current largest series of risk factors analysis for progressive spinal deformity following resection of intracanal tumors. Methods: We retrospectively analyzed the medical records of the patients with resection of intracanal tumors between January 2009 and December 2018. All patients who underwent resection of intracanal tumors performed regular postoperative follow-up were identified and included in the study. Clinical, radiological, surgical, histopathological, and follow-up data were collected. The incidence of postoperative progressive kyphosis or scoliosis was calculated. The statistical relationship between postoperative progressive spinal deformity and radiographic, clinical, and surgical variables was assessed by using univariate tests and multivariate logistic regression analysis. Results: Two hundred seventy-two patients (mean age 42.56 ± 16.18 years) with median preoperative modified McCormick score of 3 met the inclusion criteria. Among them, 7（2.6%）patients were found to have spinal deformity preoperatively, and the extent of spinal deformity in these 7 patients deteriorated after surgery. 36 (13.2%) were new cases of postoperative progressive deformity. The mean duration of follow-up was 21.8 months (median 14 months, range 6–114 months). In subsequent multivariate logistic regression analysis, age≤18 years (p=0.027), vertebral levels of tumor involvement (p = 0.019) and preoperative spinal deformity(p=0.008) was the independent risk factors (p < 0.05), increasing the odds of postoperative progressive spinal deformity by 3.94- , 0.69- and 27.11-fold, respectively. Conclusions: The incidence of postoperative progressive spinal deformity was 15.8%, mostly in these patients who had younger age (≤18 years), tumors involved in multiple segments and preoperative spinal deformity. The risk factors of postoperative progressive spinal deformity warrants serious reconsideration that when performing resection of spinal cord tumors in these patients with such risk factors, the surgeons should consider conducting follow-ups more closely, and when patients suffering from severe symptoms or gradually increased spinal deformity, surgical spinal fusion may be a more suitable choice to reduce the risk of reoperation and improve the prognosis of patients.

Background Children in household contact of adults with smear-positive tuberculosis (TB) are at higher risk of TB infection. Screening of these children is a main strategy for eliminating childhood TB.Objective To determine risk factors of TB among children in household contact with smear-positive adult TB patients.Methods This case-control study was conducted in 5 public health centers at Batu Bara District, North Sumatera. We studied children from birth to 18 year-old living in the same house as adults with smear-positive TB. A tuberculosis scoring system was used to diagnosis TB in the children. Associations between risk factors and the incidence of TB were analyzed using Chi-square, Mann-Whitney U, and logistic regression tests.Results We enrolled 145 children who had household contact with smear-positive adult TB patients. Subjects were allocated to either the case group [TB score >6; 61 subjects (42.0%)] or the control group [TB score <6; 84 subjects (58.0%)]. Bivariate analysis revealed that nutritional status, immunization status, number of people in the house, sleeping in the same bed, and duration of household contact had significant associations with the incidence of TB. By multivariate logistic regression analysis, nutritional status and duration of household contact were significant risk factors for TB, with OR 5.89 and 8.91, respectively.Conclusion Malnutrition and duration of household contact with smear-positive adult TB patients of more than 6 hours per day were risk factors for TB among children.

Abstract OBJECTIVES The goal of this study was to identify the risk factors for prolonged length of stay (LOS) in the intensive care unit (ICU) after a bidirectional cavopulmonary shunt (BCPS) procedure and its impact on the number of deaths. METHODS In total, 556 patients who underwent BCPS between January 1998 and December 2019 were included in the study. RESULTS Eighteen patients died while in the ICU, and 35 died after discharge from the ICU. Reduced ventricular function was significantly associated with death during the ICU stay (P = 0.002). In patients who were discharged alive from the ICU, LOS in the ICU [hazard ratio (HR) 1.04, 95% confidence interval (CI) 1.02–1.06; P &lt; 0.001] and a dominant right ventricle (HR 2.41, 95% CI 1.03–6.63; P = 0.04) were independent risk factors for death. Receiver operating characteristic analysis identified a cut-off value for length of ICU stay of 19 days. Mean pulmonary artery pressure (HR 1.03, 95% CI 1.01–1.05; P = 0.04) was a significant risk factor for a prolonged ICU stay. CONCLUSIONS Prolonged LOS in the ICU with a cut-off value of 19 days after BCPS was a significant risk factor for mortality. High pulmonary artery pressure at BCPS was a significant risk factor for a prolonged ICU stay.

Abstract Background Tissue expansion is used for scar reconstruction owing to its excellent clinical outcomes; however, the complications that emerge from tissue expansion hinder repair. Infection is considered a major complication of tissue expansion. This study aimed to analyze the perioperative risk factors for expander infection. Methods A large, retrospective, single-institution observational study was carried out over a 10-year period. The study enrolled consecutive patients who had undergone tissue expansion for scar reconstruction. Demographics, etiological data, expander-related characteristics and postoperative infection were assessed. Univariate and multivariate logistic regression analysis were performed to identify risk factors for expander infection. In addition, we conducted a sensitivity analysis for treatment failure caused by infection as an outcome. Results A total of 2374 expanders and 148 cases of expander infection were assessed. Treatment failure caused by infection occurred in 14 expanders. Multivariate logistic regression analysis identified that disease duration of ≤1 year (odds ratio (OR), 2.07; p &lt; 0.001), larger volume of expander (200–400 ml vs &lt;200 ml; OR, 1.74; p = 0.032; &gt;400 ml vs &lt;200 ml; OR, 1.76; p = 0.049), limb location (OR, 2.22; p = 0.023) and hematoma evacuation (OR, 2.17; p = 0.049) were associated with a high likelihood of expander infection. Disease duration of ≤1 year (OR, 3.88; p = 0.015) and hematoma evacuation (OR, 10.35; p = 0.001) were so related to high risk of treatment failure. Conclusions The rate of expander infection in patients undergoing scar reconstruction was 6.2%. Disease duration of &lt;1 year, expander volume of &gt;200 ml, limb location and postoperative hematoma evacuation were independent risk factors for expander infection.

OBJECTIVE The aim of this study was to investigate the clinical and radiological factors associated with the rupture of a vertebral artery dissecting aneurysm (VADA) and to evaluate whether the stagnation sign is a significant risk factor for rupture of VADA. METHODS Clinical and radiological variables of 117 VADAs treated in a tertiary hospital from September 2008 to December 2020 were retrospectively reviewed. The stagnation sign is defined as the finding of contrast agent remaining in the lesion until the venous phase of angiography. Univariate and multivariate analyses were executed to reveal the associations between rupture status and VADA characteristics. RESULTS The rate of ruptured VADAs was 29.1% (34 of 117) and the stagnation sign was observed in 39.3% (46 of 117). Fusiform shape (OR 5.105, 95% CI 1.591–16.383, p = 0.006), irregular surface (OR 4.200, 95% CI 1.412–12.495, p = 0.010), posterior inferior cerebellar artery (PICA) involvement (OR 3.788, 95% CI 1.288–11.136, p = 0.016), and the stagnation sign (OR = 3.317, 95% CI 1.131–9.732, p = 0.029) were significantly related to rupture of VADA in multivariate logistic regression analysis. CONCLUSIONS This study showed that fusiform shape, irregular surface, PICA involvement, and the stagnation sign may be independent risk factors for the rupture of VADA. Therefore, when the potential risk factors are observed in unruptured VADA, more aggressive treatment rather than follow-up or medical therapy may be considered.
