Incidence and Risk Factors for L5-S1 Complications After Long-level Floating Fusion in Adult Degenerative Scoliosis

Abstract Background Whether to preserve L5-S1 with no pre-existing pathology in the fusion for patients with adult degenerative scoliosis (ADS) remains controversial. This study is to determine the predictors of L5-S1 diseases for the distal fusion to L5 in the long instrumented fusion for ADS. Methods A total of 159 patients with ADS who had undergone long floating fusion were evaluated with a minimum 2 year follow-up between 2014 to 2018. The patient- and surgical-related risk factors for each individual were identified by using univariate testing. All patients were divided into groups with and without L5-S1 diseases. Univariate testing was used to identify the potential risk factors. Independent risk factors of L5-S1 diseases were identified using multivariate logistic regression. Results BMD of the patients with L5-S1 diseases were much higher than that without L5-S1 diseases (P = 0.003). Postoperative sacral slope in L5-S1 diseases group was much higher than that without L5-S1 diseases group (P = 0.000). Patient-related independent risk factors for the development of L5-S1 diseases included gender (OR = 0.41, P = 0.016) and BMD (OR = 0.42, P = 0.000). Surgical-related independent risk factors for the development of L5-S1 diseases included fusion level (OR = 2.64, P = 0.033) and postoperative sacral slope (OR = 1.43, P = 0.000).ConclusionsGender and BMD were the most common patient-related independent risk factors, Fusion levels and postoperative sacral slope were the most common surgical-related independent risk factors. Prevention of these risk factors can reduce the incidence of L5-S1 diseases in patients with long floating fusion.

ObjectiveTo investigate the incidence of gastrointestinal bleeding (GIB) in patients with acute myocardial infarction (AMI), clarify the association between adverse clinical outcomes and GIB and identify risk factors for in-hospital GIB after AMI.DesignRetrospective cohort study.Setting108 hospitals across three levels in China.ParticipantsFrom 1 January 2013 to 31 August 2014, after excluding 2659 patients because of incorrect age and missing GIB data, 23 794 patients with AMI from 108 hospitals enrolled in the China Acute Myocardial Infarction Registry were divided into GIB-positive (n=282) and GIB-negative (n=23 512) groups and were compared.Primary and secondary outcome measuresMajor adverse cardiovascular and cerebrovascular events (MACCEs) are a composite of all-cause death, reinfarction and stroke. The association between GIB and endpoints was examined using multivariate logistic regression and Cox proportional hazards models. Independent risk factors associated with GIB were identified using multivariate logistic regression analysis.ResultsThe incidence of in-hospital GIB in patients with AMI was 1.19%. GIB was significantly associated with an increased risk of MACCEs both in-hospital (OR 2.314; p<0.001) and at 2-year follow-up (HR 1.407; p=0.0008). Glycoprotein IIb/IIIa (GPIIb/IIIa) receptor inhibitor, percutaneous coronary intervention (PCI) and thrombolysis were novel independent risk factors for GIB identified in the Chinese AMI population (p<0.05).ConclusionsGIB is associated with both in-hospital and follow-up MACCEs. Gastrointestinal prophylactic treatment should be administered to patients with AMI who receive primary PCI, thrombolytic therapy or GPIIb/IIIa receptor inhibitor.Trial registration numberNCT01874691.

Background: Osteoporosis (OP) patients are usually asymptomatic until osteoporotic fractures occur, which makes early diagnosis and prevention difficult, and the associated fractures secondary to OP could be preventable with appropriate management. Therefore, early identification and relevant evidence-based management of OP could guide the prevention of subsequent fractures. This study will investigate the prevalence of OP and the incidence of osteoporotic fractures in Beijing community residents to further explore the related risk factors and put forward suggestions for people aged 45–80 years old.Methods: Over 2 years, this study will conduct an OP screening and a prospective follow-up in the Beijing community to investigate the incidence of osteoporotic fractures. The study will undertake bone mineral density detection, collect biological samples, and record information via questionnaires.Discussion: The study aims to investigate the potential risk factors for osteoporosis and explore syndromes from traditional Chinese medicine that are associated with this condition based on large samples from the Beijing community. Data on the incidence of osteoporotic fractures among community dwellers in Beijing over the two-years will be available on the Chinese clinical trial registry: ChiCTR-SOC-17013090.

Abstract Introduction: Increasing evidence indicate that coronavirus disease 2019 (COVID-19) is companied by renal dysfunction. However, the association of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2)-induced renal dysfunction with prognosis remains unclear.Materials and methods: This prospective case-cohort study analyzed 154 COVID-19 patients from the Second People’s Hospital of Fuyang City in Anhui Province. Clinical and demographic information were collected. Renal function was evaluated and its prognosis was followed up. Results: Of 154 hospitalized patients with COVID-19, 125 were common and 29 were severe patients. On admission, 16 (10.4%) patients were with renal dysfunction. Serum creatinine and cystatin C were increased, eGFR was decreased in severe patients compared with those in common patients. Renal dysfunction was more common in severe patients. By multivariate logistic regression, male, higher age and hypertension were three importantly independent risk factors of renal dysfunction in COVID-19 patients. Follow-up study found that at least one renal function marker of 3.33% patients remained abnormal in two weeks after discharge. Conclusion: Male elderly COVID-19 patients with hypertension elevates the risk of renal dysfunction. SARS-CoV-2-induced renal dysfunction are not fully recovered in two weeks after discharge.

Abstract Study design: A retrospective single center study.Objective：To identify risk factors for multiple implant-related complications with growing-rod for early-onset scoliosis.Background: High incidence of implant-related complications in the treatment of early-onset scoliosis with traditional growing rod. The risk factors for multiple implant-related complications (MIRC) have not been adequately studied.Methods: Data of 59 early-onset scoliosis patients who had been underwent growing rod surgery at Beijing Chao-yang Hospital from September 2007 to December 2017 were reviewed. All patients had complete clinical and radiographic data. Patients were divided into groups with or without MIRC. The univariate and multivariate logistic regression analysis were performed to identify the risk factors associated MIRC.Results: The average age of insertion was 8.9 years and mean follow-up was 51.91 months. 234 implantation or expansion surgeries were performed and the average operation interval was 11.4 months. A total of 60 implant-related complications occurred. Ultimately, MIRC developed in 20 (33.9%) of 59 patients. Number of surgery procedure > 3 times , follow-up time ³50 months , preoperative thoracic kyphosis > 50°, postoperative thoracic kyphosis >50°, postoperative lumbar lordosis >50°, postoperative sagittal vertical axial >40mm are potential risk factors for MIRC (P<0.1). Multivariate logistic regression analysis showed that Number of surgery procedure > 3 times, postoperative thoracic kyphosis >50°, postoperative lumbar lordosis >50°are independent risk factors for MIFRC (P<0.05), Among them, patients with postoperative thoracic kyphosis >50°had an 18.647 times higher risk of MIFRC than postoperative thoracic kyphosis angle <50°.Conclusions: Traditional growing rod in the setting of EOS has excellent clinical and radiographic outcomes but a high multiple implant-related complications. Number of surgery procedure > 3 times, postoperative thoracic kyphosis >50°, postoperative lumbar lordosis >50° are independent risk factors for MIRC.

Abstract BackgroundInflammation plays an important role in progression of the various viral pneumonia containing COVID-19, severe inflammatory responses could lead to an imbalance of immune response. The purpose of this study was to explore the possibility of the white blood count, neutrophil percentage, neutrophil-to-monocyte ratio (NMR) and neutrophil-to-lymphocyte ratio (NLR) at admission to reflect the clinical severity in patients with COVID‐19.MethodsClinical and laboratory data of adult COVID-19 patients in Changsha, China, were collected and analyzed on admission. A logistic regression model was adopted to analyze the association between the disease severity and related risk factors. The receiver operating characteristic (ROC) curve was utilized to analyze the abilities of potential risk factors in the prediction of COVID-19 severity.ResultsCompared with non-severe patients, the severe ones had significantly higher levels of neutrophil percentage (74.9% vs. 62.1%; P < 0.001), NLR (4.1 vs. 2.1; P < 0.001) and NMR (12.4 vs. 8.0; P < 0.001). A regression analysis showed that neutrophil percentage (OR,1.113; 95% CI, 1.020-1.213; P=0.016) and NMR (OR, 1.110; 95% CI, 1.002-1.230; P = 0.046) were significantly associated with severity of COVID-19 patients. ROC curve showed that the area under the curves of neutrophil percentage, NMR and the combination of them were 0.842 (95% confidence interval (CI), 0.782-0.902), 0.790 (95% CI, 0.710-0.871) and 0.851 (95% CI, 0.790-0.911), respectively.ConclusionsNeutrophil percentage and NMR may act as independent risk factors in the severity of COVID-19.

AbstractThe natural history of antiphospholipid antibodies (aPL) carriers is not well-established. The objectives of the present study were (a) to study the probability of developing clinical criteria of antiphospholipid syndrome (APS), (b) to identify potential risk factors for developing thrombosis and/or obstetric complications, (c) to study the association between the antibody profile and development of APS, and (d) to determine the efficacy of primary prophylaxis. We retrospectively analyzed 138 subjects with positive aPL who did not fulfill clinical criteria for APS. The mean follow-up time was 138 ± 63.0 months. Thirteen patients (9.4%) developed thrombosis after an average period of 73.0 ± 48.0 months. Independent risk factors for thrombosis were smoking, hypertension, thrombocytopenia, and triple aPL positivity. Low-dose acetyl salicylic acid did not prevent thrombotic events. A total of 28 obstetric complications were detected in 92 pregnancies. During the follow-up, only two women developed obstetric APS. Prophylactic treatment in pregnant women was associated with a better outcome in the prevention of early abortions. The thrombosis rate in patients with positive aPL who do not meet diagnostic criteria for APS is 0.82/100 patients-year. Smoking, hypertension, thrombocytopenia, and the aPL profile are independent risk factors for the development of thrombosis in aPL carriers. Although the incidence of obstetric complications in this population is high (31.6%), only a few of them meet APS criteria. In these women, prophylactic treatment might be effective in preventing early abortions.

Abstract IntroductionAdult non-degenerative scoliosis accounts for 90% of spinal deformities in young adults. However, perioperative complications and related risk factors of long posterior instrumentation and fusion for the treatment of adult non-degenerative scoliosis have not been adequately studied.MethodsWe evaluated clinical and radiographical results from 180 patients with adult non-degenerative scoliosis who underwent long posterior instrumentation and fusion. Preoperative clinical data, intraoperative variables, and perioperative radiographic parameters were collected to analyze the risk factors for perioperative complications. Potential and independent risk factors for perioperative complications were evaluated by univariate analysis and logistic regression analysis.Results180 adult non-degenerative scoliosis patients were included in our study. There were 31 perioperative complications for 25 (13.9%) patients, 11 of which were cardiopulmonary-related complications, five of which were infection, six of which were neurological-related complications, three of which were gastrointestinal-related complications, and six of which were incision-related problems. The independent risk factors for development of perioperative complications included change in Cobb angle (odds ratio [OR]=1.058, 95% CI=1.011~1.108, P=0.015), change in central vertical axis (CVA) (OR=1.066, 95% CI=1.019-1.116, P=0.006) and red blood cell (RBC) transfusion (OR=5.631, 95% CI=1.676~18.924, P=0.005). The area under the receiver operating characteristic (ROC) curve based on predicted probability of the logistic regression was 0.746.ConclusionsBlood transfusion, Cobb change, and CVA change were independent risk factors for perioperative complications after long-segment posterior instrumentation and fusion in adult non-degenerative scoliosis patients.

Abstract BackgroundThis study aimed to observe the mortality of patients with fragile hip fractures and assess the death-associated risk factors.MethodsSix hundred and ninety patients with osteoporotic hip fractures(aged 50-103-years-old) that were treated from January 2010 to December 2015 were enrolled in this study and followed-up and the clinical data were retrospectively examined. Three months, one year, and the total mortality during the follow-up time were measured. Mortality-related risk factors were assessed including age, gender, surgery, the duration from injury to operation, pulmonary infection, and the number and type of complications.ResultsThe 286 patients were followed up between 6 months and 42 months, with an average of 21.42±9.88 months. The three-month mortality was 7.69%, the number of patients who were followed up over one year was 231, the one-year mortality was 16.02%, and the total mortality of the follow-up time was 17.48%. The higher mortality was related to age over 75 years, associated cardio-respiratory diseases, male gender, non-operative treatment, surgery delayed over 5 days. Binary Logistic regression analysis showed that the independent risk factors affecting mortality included age (OR=5.385, P=0.003), surgery (OR=21.217, P=0.000), the number of complications (OR=9.038, P=0.000), and pre-injury cardiovascular disease (OR=3.201, P=0.041).ConclusionThe early mortality of fragile hip fractures was high and was also related to many risk factors. Age, surgery, the number of complications, and pre-injury cardiovascular disease were the independent risk factors affecting the mortality of patients with fragile hip fractures. Effective treatment without complications and early surgery can lower early mortality in patients with fragile hip fractures.

Abstract Purpose Humans have a preference for nasal breathing during sleep. This 10-year prospective study aimed to determine if nasal symptoms can predict snoring and also if snoring can predict development of nasal symptoms. The hypothesis proposed is that nasal symptoms affect the risk of snoring 10 years later, whereas snoring does not increase the risk of developing nasal symptoms. Methods In the cohort study, Respiratory Health in Northern Europe (RHINE), a random population from Denmark, Estonia, Iceland, Norway, and Sweden, born between 1945 and 1973, was investigated by postal questionnaires in 1999–2001 (RHINE II, baseline) and in 2010–2012 (RHINE III, follow-up). The study population consisted of the participants who had answered questions on nasal symptoms such as nasal obstruction, discharge, and sneezing, and also snoring both at baseline and at follow-up (n = 10,112). Results Nasal symptoms were frequent, reported by 48% of the entire population at baseline, with snoring reported by 24%. Nasal symptoms at baseline increased the risk of snoring at follow-up (adj. OR 1.38; 95% CI 1.22–1.58) after adjusting for age, sex, BMI change between baseline and follow-up, and smoking status. Snoring at baseline was associated with an increased risk of developing nasal symptoms at follow-up (adj. OR 1.22; 95% CI 1.02–1.47). Conclusion Nasal symptoms are independent risk factors for development of snoring 10 years later, and surprisingly, snoring is a risk factor for the development of nasal symptoms.
