Risk factors for progression of solitary plasmacytoma of bone to multiple myeloma in the spine: A population-based study

Abstract Background: Spine SBP is a primary spinal malignant tumor. Risk factors associated with progression of solitary plasmacytoma of bone (SBP) to multiple myeloma in spine remains unknown. This study therefore aimed to identify the risk factors associated with progression of solitary plasmacytoma of bone (SBP) to multiple myeloma in the spine.Methods: Data of 1543 patients diagnosed with spine SBP between 1992 and 2013 was obtained from the Surveillance, Epidemiology, and End Results (SEER) database for analysis. Risk factors associated with progression of SBP to multiple myeloma (MM) were then identified using univariate and multivariate regression analysis methods.Results: Out of the 1543 patients diagnosed with spine SBP, 659 of them progressed to MM. The overall rate of progression to MM was 42.51%. Univariate and multivariate regression analysis revealed that age, race, gender and chemotherapy were independent risk factors associated with SBP progression to MM.Conclusion: Old aged patients, patients belonging to the white race, female patients and those undergoing chemotherapy were identified to be at a high risk of progression to MM. This information will assist clinicians in evaluating patients’ risk of SBP progression to MM at the point of diagnosis and advise them accordingly.

Surgical Site Complications

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.

Abstract Background: SBP of spine is a primary spinal malignant tumor. Risk factors for progression of solitary plasmacytoma of bone (SBP) to multiple myeloma in spine remains controversial. We aimed to analysis the risk factors for progression of solitary plasmacytoma of bone (SBP) to multiple myeloma in spine. Methods: A total of 1543 patients diagnosed with SBP of spine in the Surveillance, Epidemiology, and End Results (SEER) database from 1992 to 2013 were included in the study. Factors associated of progression to multiple myeloma (MM) were assessed with univariate and multivariate methods. Results: 1543 patients with SBP of spine were collected and 659 patients progressed to MM. The overall rate of progression to MM was 42.51%, Age, race, gender, and chemotherapy were found to be associated with disease progression to MM in the univariate analysis, greater age (45-59: OR=2.017, 95%CI, 1.287 to 3.159; 60-74: OR=2.940, 95%CI, 1.891 to 4.570; 75-89: OR=3.180, 95%CI, 1.976 to 5.118; >89: OR=5.524, 95%CI, 1.965 to 15.526), patients of white race (OR = 2.032, 95% CI, 1.079 to 3.826), female patients (OR = 1.272, 95% CI, 1.027 to 1.576), and patients received chemotherapy (OR = 1.593, 95%CI, 1.243 to 2.042) was identified as independent risk factors for SBP of spine progression to MM in the multivariate analysis. Conclusions: Greater age, white race, female and chemotherapy was identified as independent risk factors for SBP of spine progression to MM.

Background Arterial stiffness assessed by carotid-femoral pulse wave velocity (PWV) is an independent predictor of cardiovascular morbidity and mortality. We aimed to investigate how various measures of obesity affect arterial stiffness. Methods We conducted a population-based cross-sectional survey in 8,042 South Indians above the age of 20 years. Following completion of a detailed medical history questionnaire, all participants underwent haemodynamic screening including brachial and central blood pressure, and PWV measurements using a high-fidelity applanation tonometry. The study included anthropometric measurements and fasting blood for total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL) and blood glucose (BG) levels. After the exclusion of people with previous history of diabetes, hypertension and dyslipidemia on drug therapy, 5,841 subjects (mean age 41.6 years; 58% women) constituted the study sample Results In an univariate analysis, PWV correlated positively with age, mean blood pressure (MAP), heart rate (HR), body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), body fat percent (BF%), TC, TG, LDL and BG levels (P <0.001) and negatively with HDL levels (P=0.005). In a multivariate regression analysis, majority of the PWV variability in the model was accounted for by MAP and age, (cumulative adjusted R2 change of 32.79% as compared to the total adjusted R2 change of 35.25%). However, BMI (β= 0.042; adjusted R2 change=2.83%; p<0.001) independently correlated with PWV and its contribution to the PWV variability was far more significant compared to LDL, BG and TG (cumulative adjusted R2 change=1.08%). Multivariate regression analysis using the WC, WHR, or BF% instead of the BMI continued to demonstrate a significant independent effect of obesity parameters on PWV. Conclusion: In a large a population-based cross-sectional survey the study demonstrates a positive, independent association between obesity parameters and increased arterial stiffness.

6569 Background: CRC is a common, potentially lethal, yet preventable disease. Screening tests for CRC are known to reduce the rate of death by detecting early cancer. To evaluate factors associated with the practice and impact of CRC screening, we reviewed a decade of CRC patients treated at an inner-city hospital. Methods: Under an IRB-approved protocol, data, including demographics, stage at diagnosis, utilization of screening tests, and insurance status, were obtained from CRC patients, at age 50 or above at diagnosis, treated between 1994 and 2004 at Santa Clara Valley Medical Center, a public hospital in the Silicon Valley. Chi-square test and multivariate regression analysis were used to evaluate factors associated with screening and its outcome. Results: We identified 331 cases of CRC patients who met the study criteria, with 50.5% (167) male and 49.5% (164) female patients. By ethnicity 36.6% (121) of the patients were Asian, 3.6% (12) Black, 22.8% (72) Hispanic, 37.8% (125) white, and 0.3% (1) other ethnicity. Only 5.7% (19) of the patients had been diagnosed by a screening colonoscopy, and 5.4% (18) of the patients had screening fecal occult blood test (FOBT). As a result, 9.4% (31) patients were diagnosed after either a positive colonoscopy or FOBT. Their stage distribution is presented in the table below. There was no association between the screening practice and gender, age, race or insurance status in this cohort. CRC diagnosed by screening test was significantly associated with survival benefit (p<0.01). Multivariate regression analysis revealed that survival was significantly associated with stage (p<0.05) and Hispanic race (p<0.01); but not screening test or insurance status. Conclusions: In this underserved population, even with a low rate of screening tests, screening for CRC is associated with earlier stage of CRC presentation which has been linked with survival benefit. Further studies are needed to identify barriers to CRC screening in this inner-city population. [Table: see text] No significant financial relationships to disclose.

AbstractObjectivesEvaluate the risk factors of prolonged SARS-CoV-2 virus shedding and the impact of arbidol treatment on SARS-CoV-2 virus shedding.MethodsData were retrospective collected from adults hospitalized with COVID-19 in Wuhan Union Hospital. We described the clinical features and SARS-CoV-2 RNA shedding of patients with COVID-19 and evaluated factors associated with prolonged virus shedding by multivariate regression analysis.ResultsAmong 238 patients, the median age was 55.5 years, 57.1% were female, 92.9% (221/238) used arbidol, 58.4% (139/238) used arbidol combination with interferon. The median time from illness onset to start arbidol was 8 days (IQR, 5-14 days) and the median duration of SARS-CoV-2 virus shedding was 23 days (IQR, 17.8–30 days). SARS-CoV-2 RNA clearance was significantly delayed in patients who received arbidol >7 days after illness onset, compared with those in whom arbidol treatment was started≤7 days after illness onset (HR, 1.738 [95% CI, 1.339–2.257], P < .001). Multivariate regression analysis revealed that prolonged viral shedding was significantly associated with initiation arbidol more than seven days after symptom onset (OR 2.078, 95% CI [1.114-3.876], P .004), more than 7 days from onset of symptoms to first medical visitation (OR 3.321, 95% CI[1.559-7.073], P .002), illness onset before Jan.31, 2020 (OR 3.223, 95% CI[1.450-7.163], P .021). Arbidol combination with interferon was also significantly associated with shorter virus shedding (OR .402, 95% CI[.206-.787], P .008).ConclusionsEarly initiation of arbidol and arbidol combination with interferon as well as consulting doctor timely after illness onset were helpful for SARS-CoV-2 clearance.

Abstract Background Weaning failure from cardiopulmonary bypass, postoperative low cardiac output (LCO), and cardiopulmonary resuscitation (CPR) are common scenarios preceding extracorporeal life support (ECLS) implantation after cardiac surgery. The impact of these scenarios on short- and long-term outcome are not well described. Methods Between March 2006 and December 2018, 261 patients received ECLS support after cardiac surgery. Data of patients with weaning failure (NW), postoperative LCO, and CPR leading to ECLS implantation were retrospectively analyzed regarding outcome. Risk factors for outcome after postcardiotomy ECLS were assessed by uni- or multivariate regression analysis. Results Median duration of extracorporeal support was 5.5 ± 8.5 days. Overall mortality on ECLS was 39.1%. Scenario analysis revealed weaning failure from cardiopulmonary bypass in 40.6%, postoperative LCO in 24.5%, and postoperative CPR in 34.9% leading to initiation of ECLS. Most common cause of death was refractory LCO (25.3%). Overall follow-up survival was 23.7%. Survival after weaning and during follow-up in all subgroups was 9.2% (CPR), 5.0% (LCO), and 9.6% (NW), respectively. Uni- or multivariate regression analysis revealed age, aortic surgery, and vasopressor medication level on day 1 as risk for death on support, as well as postoperative renal failure, and body mass index (BMI) as risk factors for death during follow-up. Conclusion Mortality after postcardiotomy ECLS is high. Overall, outcome after CPR, NW, weaning failure and LCO is comparable. Postoperative resuscitation does not negatively affect outcome after postcardiotomy ECLS. Neurological status of ECLS survivors is good.

Disordered Breathing

Background and Purpose Sleep disordered breathing (SBD) was reported to be a risk factor for cerebrovascular disease. We investigated the frequency of SDB in Japanese patients with acute transient ischemic attack (TIA) and stroke and the factors associated with severe SDB in Japan. Methods Between May 2010 and April 2011, we prospectively enrolled TIA and stroke patients within 24 hours of onset and performed sleep study up to 7 days after admission. SBD was defined as respiratory disturbance index (RDI: apnea or hypopnea event per hour) ≥5. Patients were divided into 2 groups according to the RDI value as follows: ≥30(severe) and <30(none or non-severe). We demonstrated the frequency of SDB and the factors associated with severe SDB were investigated by multivariate regression analysis. Results A total of 150 patients (92 males; mean age, 72.8 years) were enrolled in this study; 28 had TIA and 122 had stroke. The mean time from admission to sleep study was 4 days. Mean RDI was 22.2±17.6. SDB was observed in 126(84%) patients. Frequencies of SDB were as follows: 21(75%) patients in TIA, 105(86%) in stroke [8/10(80%) in large artery atherosclerosis, 14/14(100%) in small vessel occlusion, 37/41(90%) in cardioembolism, 46/57(81%) in other cause of stroke/undetermined]. Severe SDB was observed in 44 (29%) patients; 21% in TIA and 31% in stroke. Frequencies of male (75% for the severe SDB group vs. 56% for the non-severe SDB group, p=0.027), atrial fibrillation (39% vs. 23%, p=0.045), body mass index (23.8±3.8 vs. 22.3±3.8, p=0.043), and neck circumference (37.8±4.3 vs. 35.8±4.2, p=0.012) were significantly higher in the severe SDB than in the non-severe SDB. Metabolic syndrome (36% vs. 21%, p=0.057) and waist circumference (88.9±9.8 vs. 85.5±9.3, p=0.080) showed a tendency toward higher in the severe SDB group than in the non-severe SDB group. There were no significant differences in age, prior stroke, vascular risk factors, Glasgow Coma Scale, and NIHSS score on admission. On multivariate regression analysis, atrial fibrillation (odds ratio, 2.5; 95% confidence interval, 1.079-5.836, p=0.0326) was found to be independently associated with severe SDB. Conclusions Most Japanese patients with acute TIA and stroke had SDB, and the presence of atrial fibrillation was associated with severe SDB.
