Risk Factors Associated With New-Onset Diabetes After Liver Transplant: A Case Control Study

BackgroundNew-onset diabetes after transplant is a severe complication that can present in liver transplant recipients, negatively impacting quality of life and graft survival. It also contributes to increased risk of infection, cardiovascular disease, and rejection, which are the main causes of death among liver transplant recipients. The aim of the present study was to assess the risk factors associated with new-onset diabetes after transplant.MethodThis was a case control study based on the data from 146 liver transplant patients at a reference hospital. The data from the charts were collected using a 2-part form: Part I (sociodemographic variables) and Part II (clinical variables).ResultsMultiple analysis showed that pre-existing systemic arterial hypertension (odds ratio [OR], 2.65; 95% CI, 1.12–6.28) and the use of sodium mycophenolate associated with tacrolimus (OR, 2.68; 95% CI, 1.02–7.06) increased the risk of new-onset diabetes after transplant. On comparing the anthropometric variables, lipid panel, and blood glucose levels of liver transplant patients with and without diabetes, higher glycemic levels were found in the group with diabetes (P < .001).ConclusionPre-existing systemic arterial hypertension and the associated use of sodium mycophenolate and tacrolimus increased the risk of new-onset diabetes after transplant.     

Development of a postoperative delirium risk scoring tool using data from the Australian and New Zealand Hip Fracture Registry: an analysis of 6672 patients 2017-2018

Background and purposeThis study aimed to determine the incidence, predictors of postoperative delirium and develop a post-surgery delirium risk scoring tool.Patients and MethodsA total of 6672 hip fracture patients with documented assessment for delirium were analyzed from the Australia and New Zealand Hip Fracture Registry between June 2017 and December 2018.Thirty-six variables for the prediction of delirium using univariate and multivariate logistic regression were assessed. The models were assessed for diagnostic accuracy using C-statistic and calibration using Hosmer-Lemeshow goodness-of-fit test. A Delirium Risk Score was developed based on the regression coefficients.ResultsDelirium developed in 2599/6672 (39.0%) hip fracture patients. Seven independent predictors of delirium were identified; age above 80 years (OR=1.6 CI 1.4-1.9; p=0.001), male (OR=1.3 CI 1.1-1.5; p=0.007), absent pre-operative cognitive assessment (OR=1.5 CI 1.3-1.9; p=0.001), impaired pre-operative cognitive state (OR=1.7 CI 1.3 -2.1; p=0.001), surgery delay (OR=1.7 CI 1.2-2.5; p=0.002) and mobilisation day 1 post-surgery (OR=1.9 CI 1.4-2.6; p=0.001). The C-statistics for the training and validation datasets were 0.74 and 0.75, respectively. Calibration was good (χ2=35.72 (9); p<0.001). The Delirium Risk Score for patients ranged from 0 to 42 in the validation data and when used alone as a risk predictor, had similar levels of diagnostic accuracy (C-statistic=0.742) indicating its potential for use as a stand-alone risk scoring tool.ConclusionWe have designed and validated a delirium risk score for predicting delirium following surgery for a hip fracture using seven predicting factors. This could assist clinicians in identifying high risk patients requiring higher levels of observation and post-surgical care.     

Enhanced surveillance of tetanus toxoid,reduced diphtheria toxoid,and acellular pertussis (Tdap) vaccines in pregnancy in the Vaccine Adverse Event Reporting System (VAERS), 2011–2015

BackgroundIn October 2011, the Advisory Committee on Immunization Practices (ACIP) issued updated recommendations that all pregnant women routinely receive a dose of tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine.ObjectivesWe characterized reports to the Vaccine Adverse Event Reporting System (VAERS) in pregnant women who received Tdap after this updated recommendation (2011–2015) and compared the pattern of adverse events (AEs) with the period before the updated recommendation (2005–2010).MethodsWe searched the VAERS database for reports of AEs in pregnant women who received Tdap vaccine after the routine recommendation (11/01/2011–6/30/2015) and compared it to published data before the routine Tdap recommendation (01/01/2005–06/30/2010). We conducted clinical review of reports and available medical records. The clinical pattern of reports in the post-recommendation period was compared with the pattern before the routine Tdap recommendation.ResultsWe found 392 reports of Tdap vaccination after the routine recommendation. One neonatal death but no maternal deaths were reported. No maternal or neonatal deaths were reported before the recommendation. We observed an increase in proportion of reports for stillbirths (1.5–2.8%) and injection site reactions/arm pain (4.5–11.9%) after the recommendation compared to the period before the routine recommendation for Tdap during pregnancy. We noted a decrease in reports of spontaneous abortion (16.7–1%). After the 2011 Tdap recommendation, in most reports, vaccination (79%) occurred during the third trimester compared to 4% before the 2011 Tdap recommendation. Twenty-six reports of repeat Tdap were received in VAERS; 13 did not report an AE. One medical facility accounted for 27% of all submitted reports.ConclusionsNo new or unexpected vaccine AEs were noted among pregnant women who received Tdap after routine recommendations for maternal Tdap vaccination. Changes in reporting patterns would be expected, given the broader use of Tdap in pregnant women in the third trimester.     

The Impact of Job Conditions on Health-Related Quality of Life among Working Japanese Older Adults: A Five-Year Longitudinal Study Using J-MICC Okazaki Study Data

ObjectivesThe number of older adults who continue working after retirement is increasing in Japan. Little is known about how job conditions affect older adults’ health. We examined the association between job conditions and health-related quality of life (HRQOL) during a five-year follow-up study.MethodsThis study included participants aged 65 years or older from the Japan Multi-Institutional Collaborative Cohort Study in the Okazaki area recruited at baseline between 2007 and 2011 and followed up five years later. Participants completed a self-reported questionnaire on the physical and mental health aspects of HRQOL (SF-8™), employment status, and job conditions (job satisfaction, skill use, and job suitability).ResultsData of 1,146 men and 522 women were analyzed (mean age: 69.1 and 68.6 years, respectively). Generalized mixed linear regression analysis revealed that, compared to the not-working group, skill use was positively associated with mental health aspects among men (skill use × time: β = 0.16, SE = 0.08, p < 0.05), while poor job satisfaction and job suitability were negatively associated with mental health aspects among women (job satisfaction, not satisfied × time: β = -0.93, SE = 0.47, p < 0.05; job suitability, not suitable × time: β = -1.06, SE = 0.50, p < 0.05).ConclusionsRegarding job conditions among older adults, skill use in men was marginally associated with mental health, and poor job satisfaction and suitability in women were negatively associated with mental health. Considering the job conditions of older workers is necessary to protect their mental health.     

Impact of using concomitant conventional DMARDs on adherence to biologic DMARD treatment in rheumatoid arthritis: Multi-centre,population-based cohort study

PurposeTo evaluate the impact of concomitant use of conventional synthetic DMARDs (csCMARD) on adherence, switching and dose of biologic disease modifying antirheumatic drugs (bDMARD) in rheumatoid arthritis (RA) patients treated with bDMARDs.Patients and methodsThis was a population-based cohort study conducted in five provinces of Canada (Alberta, Manitoba, Ontario, Quebec, and Saskatchewan), and one American database (IBM® MarketScan® Databases). Adult RA patients entered the study after a 3-month initiation period of bDMARDs between 1 January 2007, and 30 March 2014. Concomitant csDMARD exposure was compared to non-csDMARD exposure on the following outcomes: discontinuation of bDMARD therapy, switching of bDMARDs, and percent change in dose of bDMARD compared to initial dose. The effect of the time-varying changes in csDMARD exposure was analyzed using marginal structural models. Dose change was analyzed using linear regression. Results from each participating site were combined using likelihood ratio meta-analysis.ResultsThe study population comprised 20,221 new users of bDMARDs: adalimumab (7609), etanercept (9809), abatacept (1024), infliximab (1779). Concomitant use of csDMARD therapy was not significantly associated with reduced discontinuation of bDMARD treatment (hazard ratio 0.90, 95% intrinsic confidence interval 0.79 to 1.02) or reduced switching of bDMARDs (hazard ratio 0.95, 95% intrinsic confidence interval 0.80 to 1.11), but was associated with a small increase in bDMARD dose compared to the mean dose over the first three months of treatment (mean percentage change in dose +0.56% mg/day, 95% intrinsic confidence interval +0.14% to +0.97%).ConclusionIn this large study of RA patients using bDMARDs in Canada and the United States, we found no clear evidence that patients who received concomitant csDMARD therapy were less likely to discontinue, switch or increase their dose of bDMARD.     

Molecular detection of Orientia tsutsugamushi strains circulating in Nagaland

The antigenic heterogeneity of Orientia in India is still unknown in many disease endemic areas. The present study aims to characterize the strains of O. tsutsugamushi circulating in Nagaland, Northeast India. Two patients clinically diagnosed with ST and hospitalized in Mon district hospital, Nagaland were identified from whom eschar tissues were collected. Both patients demonstrated antibodies against O. tsutsugamushi along with positive PCR amplification for 56 ?kDa gene. The prototype strain TA763 shared 90.4% homology with the sequences. Both the sequences formed a distinctive cluster demonstrating 100% similarity with strains identified from Thailand, Vietnam, China and southern parts of India.
