Objectives: Methadone can be fatal due to respiratory failure even in little doses. This study aimed to evaluate the possible risk factors of death and/or intubation in methadone-poisoned children of 12 years or younger. Design: Retrospective routine database study.Setting: The only tertiary hospital for children poisoning in Tehran.Patients: Four hundred fifty-three methadone-poisoned patients aged 12 or younger were studied between 2001 and 2012.Main Outcome Measures: In-hospital mortality and intubation/mechanical ventilation.Results: Of a total of 475 children included, 22 were excluded due to coingestion of other drugs. Three (0.66 percent) expired and 12 (2.65 percent) were intubated during the course of hospital stay. Intubation (p < 0.001), fever (T axillary ≥ 37.5 °C, p = 0.01), being unresponsive at presentation (p = 0.02), tachycardia (p = 0.01), acidosis (p = 0.03), leukocytosis (p = 0.02), and longer hospital stay (p = 0.01) associated with death. Mortality (p < 0.001), fever (p = 0.004), aspartate aminotransferase (AST; p = 0.006), alanine transaminase (p = 0.04), creatinine (p = 0.005), corrected QT (QTc) interval in triage electrocardiogram (p = 0.02), and longer hospital stay (p = 0.005) associated with intubation in univariate analysis. However, after running regression analysis, only fever, QTc ≥ 480 ms, tachycardia, and AST independently associated with intubation and death. Axillary T ≥ 37.45 °C with an accuracy of 91.9 (95% confidence interval [CI] 88.8-94.2) and odds ratio of 9.3 (95% CI 2.5-34.9) predicted intubation, and T ≥ 37.75 with an accuracy of 96.0 (95% CI 93.5-97.5) and odds ratio of 47.4 (95% CI 4.1-550.1) predicted death. Conclusion: A methadone-poisoned child presenting with tachycardia, fever, abnormal AST, or an initial prolonged QTc interval should be managed with great caution.

Abstract Introduction Prolonged QT interval is associated with cardiac arrhythmias and sudden death. This study determined the prevalence of QT intervals corrected for heart rate (QTc) among adults admitted for executive check up in a tertiary hospital with Type 2 diabetes and its associations with metabolic control. Methods This cross-sectional study included 111 adult patients with Type 2 diabetes and 152 control patients admitted for executive check up in a tertiary hospital. A standard 12-lead electrocardiogram was recorded. Corrected QT interval (QTc) of &gt;440 ms was considered abnormally prolonged and QTc &gt;500 ms was considered a high-risk QTc. Demographic, clinical and laboratory data were collected. Independent risk factors for prolonged QTc were assessed using logistic regression analysis. Results QTc duration was statistically significant between subjects with Type 2 diabetes and control subjects (mean duration 434 vs 419 ms; P=0.003). Prevalence of prolonged QTc among type 2 diabetics is 41.4% and 28% in the control group. In the diabetic group 2.7% has a QTc of &gt;500. Independent risk factors for prolonged QTc using univariate logistic regression analysis is presence of diabetes type 2 (OR = 2.00, p=0.008), HBA1c (OR = 1.23, p=0.050) and intake of DPP4 (OR=6.46, (p≤0.001). Independent risk factors for prolonged QTc using multivariate logistic regression analysis is intake of DPP4 inhibitors (OR=6.26, p=0.023). Conclusion There is no significant correlation between HBA1C and QTc interval. The prevalence of prolonged QTc is relatively high among diabetics but the prevalence of high risk QTc interval is relatively low. Intake of DPP4 inhibitors is an independent risk factor in QT prolongation. FUNDunding Acknowledgement Type of funding sources: None.

Purpose: Reintubation following unplanned extubation (UE) is often required and associated with increased morbidity; however, knowledge of risk factors leading to reintubation and subsequent outcomes in children is still lacking. We sought to determine the incidence, risk factors, and outcomes related to reintubation after UEs. Methods: All mechanically ventilated children were prospectively tracked for UEs over a 7-year period in a pediatric intensive care unit. For each UE event, data associated with reintubation within 24 hours and outcomes were collected. Results: Of 757 intubated patients, 87 UE occurred out of 11 335 intubation days (0.76 UE/100 intubation days), with 57 (65%) requiring reintubation. Most of the UEs that did not require reintubation were already weaning ventilator settings prior to UE (73%). Univariate analysis showed that younger children (<1 year) required reintubation more frequently after an UE. Patients experiencing UE during weaning experienced significantly fewer reintubations, whereas 90% of patients with full mechanical ventilation support required reintubation. Logistic regression revealed that requirement of full ventilator support (odds ratio: 37.5) and a COMFORT score <26 (odds ratio: 5.5) were associated with UE failure. There were no differences between reintubated and nonreintubated patients regarding the length of hospital stay, ventilator-associated pneumonia rate, need for tracheostomy, and mortality. Cardiovascular and respiratory complications were seen in 33% of the reintubations. Conclusion: The rate of reintubation is high in children experiencing UE. Requirement of full ventilator support and a COMFORT score <26 are associated with reintubation. Prospective research is required to better understand the reintubation decisions and needs.

Abstract Background and Aims Association between nephrotic syndrome (NS) and cancer is well known. However, it has been barely studied and scarcely sustained. Membranous nephropathy (MN) has been identified often as a glomerular paraneoplastic disease. Reported incidence of cancer at the time of biopsy or one year follow-up of MN is 10-20%. Incidence rates in other glomerulopathies are limited. Concomitant malignancy is associated with poor renal outcome in NS. Therapy for cancer is priority and immunosuppressives therapies should be restricted. Furthermore, there is no consensus for cancer screening in patients with NS with or without known risk factors for cancer, as smoking or alcohol consumption. The aim of our study is to stablish the incidence of neoplasia in a cohort of patients of a tertiary hospital of Spain who develop NS. We analyze clinical characteristics, glomerular disease, type of malignancies, screening procedures and risk factors for cancer in this population. Method All patients with NS at our center between January 2013 and December 2019 were included. Demographical and clinical data, and laboratory results were collected, as well as all tests performed for cancer screening. Patients who presented cancer the year before or 24 months after the diagnosis of NS were identified. We performed a logistic regression model to identify independent risk factors for cancer in this population. Results During the study period, 47 patients presented with NS at our center. 38.3% were women and mean age was 57.28±17.3 years. 46.8% patients presented high blood pressure and 23.4% type 2 DM. 5 patients presented HIV infection, and 4 hepatitis C. 51% reported smoking, and 19% of alcohol consumption. Mean creatinine at NS diagnosis was 2.48±2.30 mg/dL, and proteinuria 10.9±6.7 g per day. Histologic diagnosis were: MN (n=7), membranoproliferative glomerulonephritis (n=5), diabetic nephropathy (n=5), and focal and segmental glomerulosclerosis (n=4). 9 out 47 patients presented cancer: 6 patients had a malignancy diagnosed the year before the NS onset (prostate carcinoma n=2, gastrointestinal carcinoma n=2, lung carcinoma n=1, and Hodgkin lymphoma n=1), and 3 patients one the year after the NS onset (thyroid carcinoma n=1, melanoma n=1, and multiple myeloma n=1). In the univariate analysis, patients with cancer were older (69.3±12.1 vs 54.4±17.2 years old, p=0.018) and had more frequently alcohol consumption (33.3% vs 15.8%, p=0.0187). There were no differences in terms of smoking, viral infections, renal function, proteinuria or type of glomerulopathy. In multivariate analysis including these two variables and gender, neither age nor alcohol intake were a risk factors for the presence of cancer in patients with NS. Conclusion: 19.1% patients with NS presented also concomitant cancer in our cohort, without association to the type of glomerulopathy, age or known risk factors for neoplasia such as alcohol, tobacco or viral infection. As our data showed, the presence of cancer in patients with NS is considerable, so the development of screening strategies to find occult malignancies in this group of patients is necessary since this condition compromises renal outcome and life expectancy

Introduction & Hypothesis: Data on long-term outcomes after tissue-plasminogen activator (tPA) therapy are limited. We evaluated the rate of favorable outcomes and mortality at 5 years after tPA therapy and investigated factors related to long-term clinical outcomes. Methods: Telephone interviews were used to assess the to the the modified Rankin Scale (mRS) scores at 3 months, 6 months, 1 year, 2 years, 3 years, 4 years, and 5 years after tPA therapy after written informed consent was obtained. When a telephone interview was not successfully accomplished, an interview letter was sent as an alternative method. Favorable outcome was defined as mRS 0-2, and unfavorable outcome was as mRS 3-6. Multivariate logistic regression analysis was conducted to investigate factors associated with favorable outcomes and mortality at 5 years after tPA therapy. Results: From 2005 to 2013, 256 (median age, 77 [interquartile range, 68-84] years; 157 [61%] males) patients were enrolled. The onset-to-treatment time (OTT) was 153 (120-176) minutes. At 3 months after tPA therapy, the median mRS score was assessed as 3 (1-5). Kaplan-Meier curve showed that favorable outcomes after 5 years after tPA therapy occurred in 45% patients and that the mortality rate was 40%. Univariate analysis showed that OTT was 123 (107-172) minutes in patients with favorable outcomes and 155 (124-172) minutes in patients with non-favorable outcomes (p=0.046). In addition, OTT was 157 (133-172) minutes in the death group and 123 (106-169) minutes in the survival group (p=0.001). Multivariate regression analysis indicated that OTT was an independent factor related to favorable outcomes (odds ratio 0.97, 95% confidence interval 0.95-0.99, p=0.008) and mortality (odds ratio 1.04, 95% confidence interval 1.02-1.06, p=0.001). Receiver operating characteristic curve analysis showed that OTT ≥ 136 minutes was the optimal cut-off value to predict favorable outcome at 5 years after tPA therapy, with a sensitivity of 0.67, a specificity of 0.70, and an area under curve (AUC) of 0.662 (p=0.016), and that to predict death within 5 years after tPA therapy, with a sensitivity of 0.70, a specificity of 0.66, and an AUC of 0.679 (p=0.001). Conclusion: Early tPA administration can improves long-term clinical outcomes.

Abstract Background: In contrast to open-surgery abdominoperineal excision (APE) for rectal cancer, postoperative perineal hernia (PPH) is reported to increase after extralevator APE and endoscopic surgery. In this study, therefore, we aimed to determine the risk factors for PPH after endoscopic APE.Methods: A total 73 patients who underwent endoscopic APE for lower rectal cancer were collected from January 2009 to March 2020, and the risk factors for PPH were analyzed retrospectively.Results: Nineteen patients (26%) developed PPH after endoscopic APE, and the diagnosis of PPH was made at 9–393 days (median: 183 days) after initial surgery. Logistic regression analysis showed that absence of pelvic peritoneal closure alone increased the incidence of PPH significantly (odds ratio; 13.76, 95% confidence interval; 1.48–1884.84, p = 0.004).Conclusions: Pelvic peritoneal closure should be performed when possible after endoscopic APE to prevent PPH.

Abstract Background: Chronic kidney disease (CKD) increases the susceptibility to the infection of herpes zoster (HZ). Less is known about the risk factors of HZ in CKD patients.Methods and Participants: This is a case-control study. CKD patients diagnosed with HZ infection between January 2015 and October 2020 in a tertiary hospital were identified. One age- and gender- matched control was paired for each case, matched to the date of initial HZ diagnose. The uni- and multivariate analysis were used to evaluate the risk factors for development of HZ in CKD patients.Results: Forty-six HZ patients and controls were identified. In general, about 80% (72 out of 92) patients were classified at end-stage renal disease (ESRD, CKD Ⅳ to Ⅴ). Multivariate analyses revealed that immunosuppressive agents (odds ratio: 12.50, 95% CI: 1.53-102.26, P=0.021) and dialysis (odds ratio: 3.33, 95% CI: 1.13-9.78, P=0.029) were independent risk factors of HZ in patient with CKD. Conclusion: Immunosuppressive medication and dialysis were associated with HZ infection in CKD. Further guideline may highlight the necessity of zoster vaccine for patients with CKD, who undertake immunosuppressive or dialysis treatment.

Objective. To determine the novel proposed nomogram model accuracy in the prediction of the lower-extremity amputations (LEA) risk in diabetic foot ulcer (DFU). Methods and Materials. In this retrospective study, data of 125 patients with diabetic foot ulcer who met the research criteria in Zhongnan Hospital of Wuhan University from January 2015 to December 2019 were collected by filling in the clinical investigation case report form. Firstly, univariate analysis was used to find the primary predictive factors of amputation in patients with diabetic foot ulcer. Secondly, single factor and multiple factor logistic regression analysis were employed to screen the independent influencing factors of amputation introducing the primary predictive factors selected from the univariate analysis. Thirdly, the independent influencing factors were applied to build a prediction model of amputation risk in patients with diabetic foot ulcer by using R4.3; then, the nomogram was established according to the selected variables visually. Finally, the performance of the prediction model was evaluated and verified by receiver working characteristic (ROC) curve, corrected calibration curve, and clinical decision curve. Results. 7 primary predictive factors were selected by univariate analysis from 21 variables, including the course of diabetes, peripheral angiopathy of diabetic (PAD), glycosylated hemoglobin A1c (HbA1c), white blood cells (WBC), albumin (ALB), blood uric acid (BUA), and fibrinogen (FIB); single factor logistic regression analysis showed that albumin was a protective factor for amputation in patients with diabetic foot ulcer, and the other six factors were risk factors. Multivariate logical regression analysis illustrated that only five factors (the course of diabetes, PAD, HbA1c, WBC, and FIB) were independent risk factors for amputation in patients with diabetic foot ulcer. According to the area under curve (AUC) of ROC was 0.876 and corrected calibration curve of the nomogram displayed good fitting ability, the model established by these 5 independent risk factors exhibited good ability to predict the risk of amputation. The decision analysis curve (DCA) indicated that the nomogram model was more practical and accurate when the risk threshold was between 6% and 91%. Conclusion. Our novel proposed nomogram showed that the course of diabetes, PAD, HbA1c, WBC, and FIB are the independent risk factors of amputation in patients with DFU. This prediction model was well developed and behaved a great accurate value for LEA so as to provide a useful tool for screening LEA risk and preventing DFU from developing into amputation.

Abstract Background: The aims of this study were to describe the epidemiology and demographic characteristics of critically ill children requiring continuous renal replacement therapy (CRRT) at our pediatric intensive care unit (PICU) and to explore risk factors associated with mortality. Methods: A retrospective cohort of 121 critically ill children who received CRRT from May 2015 to May 2020 in the PICU of a tertiary healthcare institution was evalauted. The demographic information, admission diagnosis, indication for CRRT, clinical variables at the initiation of CRRT, time related variables and the laboratory results at initiation of CRRT were compared between survivors and non-survivors.Results: The most common diagnoses were renal disease (30.6%), hemato-oncological disease (12.4%), and sepsis (11.6%). The overall mortality was 29.8%. When compared according to diagnosis at admission, we found that patients with hemato-oncologic disease (73.3%) and those with pneumonia/respiratory failure (72.7%) had the highest mortality, while patients with renal disease had the lowest mortality (5.4%). The most common CRRT indications were: electrolyte or acid base imbalance (38.8%), acute kidney injury (29.8%) and fluid overload (14.9%). There was no relationship between mortality and indication for CRRT. The time interval between PICU admission and CRRT initiation was also unassociated with mortality (p=0.146). In patients diagnosed with sepsis, time until the initiation of CRRT was significantly shorter in survivors compared to non-survivors (p=0.004). Based on multivariate logistic regression, presence of comorbidity (odds ratio: 5.71; %95 CI: 1.16-27.97), being diagnosed with pneumonia/respiratory failure at admission (odds ratio: 16.16; %95 CI: 1.56-167.01), and high lactate level at the initiation of CRRT (odds ratio: 1.43; %95 CI: 1.17-1.79) were independently associated with mortality.Conclusions: In the context of the population studied mortality rate was lower than previously reported. In critically ill children requiring CRRT, mortality seems to be related to underlying disease, presence of comorbidity, and high lactate levels at CRRT initiation. We also found that early initiation of CRRT in sepsis can reduce mortality.

Background: The purpose of this study was to identify independent risk factors associated with an increased rate of surgical site complications after elective hand surgery. Methods: This study is a retrospective review of all patients who underwent elective hand, wrist, forearm, and elbow surgery over a 10-year period at a single institution. Electronic medical records were reviewed, and information regarding patient demographics, past medical and social history, perioperative laboratory values, procedures performed, and surgical complications was collected. Surgical site complications included surgical site infections, seromas or hematomas, and delayed wound healing or wound dehiscence. A univariate analysis was then performed to identify potential risk factors, which were then included in a multivariate regression analysis. Results: A total of 3261 patients who underwent elective hand surgery and met the above inclusion and exclusion criteria were included in this study. The mean age was 57 years, with 65% female and 35% male patients. The overall surgical complication rate was 2.2%. Univariate analysis of patient factors identified male sex; number of procedures >1; history of drug, alcohol, or smoking use; American Society of Anesthesiologists (ASA) class III and IV; and serum albumin <3.5 mg/dL to be significantly associated with complications. However, multivariate regression analysis identified that only ASA class III and IV (odds ratio = 3.27) was significantly associated with surgical complications. Conclusions: Patients classified as ASA class III or IV were identified to be at a significantly increased risk of complications following elective hand surgery. Health factors which triage patients into these 2 groups may represent potentially modifiable factors to mitigate perioperative risk in the elective hand surgery population.

Objective To determine the predictive value of nasal endoscopic findings and symptoms in the diagnosis of granulomatosis with polyangiitis (GPA). Study Design A cross-sectional study. Setting A tertiary university hospital. Subjects and Methods A total of 116 adults were enrolled in the study: 19 patients with GPA, 29 patients with other rheumatic diseases, and 68 healthy volunteers. All patients were examined with a flexible endoscope, and nasal endoscopic images were recorded and evaluated blindly. The medical history of each patient was taken by a physician blinded to the patient’s diagnosis. Results Univariate analysis indicated a statistically significant difference in rhinorrhea ( P = .002), postnasal drip ( P = .015), epistaxis ( P < .001), and saddle nose ( P = .017). However, binary logistic regression analysis demonstrated that only history of epistaxis ( P = .012; odds ratio, 5.6) was statistically significant in predicting GPA. Univariate analysis showed a statistically significant difference in nasal secretion ( P = .028), nasal septal perforation ( P < .017), nasal crusting ( P < .001), nasal adhesion ( P < .001), nasal granuloma ( P = .017), and hemorrhagic fragile nasal mucosa ( P < .001). A binary logistic regression analysis demonstrated that only hemorrhagic fragile nasal mucosa ( P < .001; odds ratio, 52.9) was a statistically significant predictor of GPA. Conclusions Given the results of this study, we believe that hemorrhagic fragile nasal mucosa and history of recurrent epistaxis may put patients at risk for GPA and should be investigated accordingly.
