Impact of Diabetes Mellitus Following Tonsillectomy in Adults: A National Surgical Quality Improvement Program Analysis.

To identify 30-day complication rates specific to patients with diabetes mellitus following tonsillectomy. The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients undergoing tonsillectomy between 2005 and 2018. Patients were stratified into 3 cohorts: insulin-dependent diabetes mellitus (IDDM), non-insulin-dependent diabetes mellitus (NIDDM), and non-diabetes mellitus (NODM). Coarsened-exact-matching was utilized to account for baseline differences between cohorts. Outcomes studied included post-operate complications, prolonged hospitalization, and unplanned readmissions. A total of 986 DM and 26 774 NODM patients were included, and the mean age of patients undergoing tonsillectomy was 29.5 ± 11.6 and 28.7 ± 11.0 years, respectively. The majority of patients were female (70.5% for both DM and NODM cohorts) and White/Caucasian (89.2% vs 89.3%). Among patients undergoing tonsillectomy, a greater proportion of DM patients experienced an operative time greater than or equal to the 75th percentile (35 minutes; 25.9% vs 22.8%, P = .024), overall morbidity (12.6% vs 5.4%, P < .001), pneumonia (0.6% vs 0.2%, P = .036), and reoperation (10.2% vs 3.5% P < .001) in comparison to NODM patients. In an analysis between IDDM (n = 379) and NIDDM (n = 211) patients, IDDM patients were at an increased risk for prolonged hospitalization (1.4% vs 0.0%, P = .045), pneumonia (5.2% vs 0.5%, P < .001), urinary tract infections (3.3% vs 0.3% P = .004), major complications (15.6% vs 7.7%, P = .002), minor complications (19.9% vs 8.2%, P < .001), and overall complications (10.0% vs 1.3%, P < .001). DM patients are at a heightened risk for complications following tonsillectomy. Standardized protocols, careful pre-operative planning, and stringent glycemic management may help optimize patient outcomes.

Association of HLA-DRB1 and -DQ Alleles and Haplotypes with Type 1 Diabetes in Jordanians.

The Human Leukocyte Antigen (HLA) class II genes, particularly the HLADR and -DQ loci, have been shown to play a crucial role in Type 1 Diabetes (T1D) development. This study is the first to examine the contribution of the HLA-DR/DQ alleles and haplotypes to T1D susceptibility in Jordanians. Polymerase chain reaction sequence-specific primers (PCR-SSP) were used to genotype 41 Jordanian healthy controls and 50 insulin-dependent diabetes mellitus (IDDM) patients. The following alleles were found to be significant high risk alleles in T1D Jordanian patients: DRB1*04 (OR=3.95, p<0.001), DRB1*0301(OR=5.27, p<0.001), DQA1*0301 (OR=5.67, p<0.001), DQA1*0501(OR=3.18, p=0.002), DQB1*0201(OR=2.18, p=0.03), DQB1*0302 (OR=5.67, p<0.001). However, Jordanians harboring the DRB1*0701 (OR=0.37, p=0.01), DRB1*1101 (OR=0.2, p=0.01), DQA1*0505 (OR=0.31, p=0.02), DQA1*0103 (OR=0.33, p=0.04), DQA1*0201 (OR=0.45, p=0.04), DQB1*0301 (OR=0.23, p=0.001), DQB1*0501 (OR=0.18, p=0.009) alleles had a significantly lower risk of developing T1D. A strong positive association of DRB1*04-DQA1*0301-DQBl*0302 (OR=5.67, p<0.001) and DRB1*0301-DQA1*0501-DQB1*0201 (OR=6.24, p<0.001) putative haplotypes with IDDM was evident in Jordanian IDDM patients whereas DRB1*1101-DQA1*0505- DQB1*0301 (OR=0.23, p=0.03) was shown to have a protective role against T1D in Jordanians. Our findings show that specific HLA class II alleles and haplotypes are significantly associated with susceptibility to T1D in Jordanians.

A study of association of proteinuria with hba1c in diabetes mellitus

Diabetic nephropathy occurs in as many as 30% of insulin dependent diabetes mellitus patients and 25% of noninsulin-dependent diabetes mellitus patients. Diabetic nephropathy is a dreaded disease with progressive and continuous. Deterioration in glomerular function resulting in irreversible renal failure. Diabetic nephropathy is an important cause of morbidity and mortality and is now among the most common cause of end-stage renal disease. However, there is an early phase of diabetic renal disease called incipient diabetic nephropathy. This study is intended to study the association of Proteinuria with HbA1C in Diabetes Mellitus.

Insulin-Dependent Diabetic Patients are at Increased Risk of Postoperative Hyperglycemia When Undergoing Total Joint Arthroplasty

BackgroundDiabetic patients are at an increased risk of prosthetic joint infection (PJI) after total joint arthroplasty (TJA). The relationship between insulin-dependence and PJI has not been investigated. We aimed at evaluating whether insulin-dependent diabetes mellitus (IDDM) patients were more susceptible to postoperative hyperglycemia and PJI than their non–insulin-dependent diabetes mellitus (NIDDM) counterparts. MethodsA retrospective review was conducted of diabetic patients undergoing TJA (hip or knee) from January 2011 to December 2016. Preoperative hemoglobin A1c (A1c) and postoperative glucose measurements were observed. Patients were stratified as IDDM or NIDDM. The A1c values that predicted hyperglycemia >200 mg/dL for each group were calculated. Primary end point was postoperative hyperglycemia >200 mg/dL and secondary end point was PJI. ResultsThere were 773 patients meeting inclusion criteria. The IDDM cohort had a higher preoperative A1c (6.97% vs 6.28%, P < .0001) and postoperative glucose (235.2 vs 163.5, P < .0001). IDDM patients were more likely to have postoperative hyperglycemia (63.84% vs 20.83%, P < .0001; odds ratio, 5.2; 95% confidence interval, 3.66-7.4). Overall, an A1c of >7.45% predicted postoperative hyperglycemia >200 mg/mL (odds ratio, 6.94; 95% confidence interval, 4.32-11.45). When separating our 2 cohorts, an A1c of >6.59% in IDDM, and >6.60% in NIDDM, was associated with an increased risk of postoperative hyperglycemia (P < .0001). PJI was similar between the 2 cohorts (2.52% vs 2.38%, P = .9034). ConclusionIDDM patients undergoing TJA are 5.2 times more likely to have postoperative hyperglycemia >200 mg/dL than their NIDDM counterparts, although increased risk of PJI was not found in this study. Despite the higher A1c and postoperative hyperglycemia in IDDM patients, there was found to be no clinical difference between A1c cutoff values for postoperative hyperglycemia between IDDM and NIDDM patients.

Delayed gastric emptying in diabetic patients undergoing pancreaticoduodenectomy: A procedure-targeted nsqip analysis

Presenter: Alissa Greenbaum MD | Rutgers University Background: Delayed gastric emptying (DGE) is a major source of morbidity after pancreaticoduodenctomy (PD), occurring in up to 20% of patients. Patients with type I or II diabetes mellitus (DM) have a propensity for gastric dysmotility, however the exact relationship between DGE and DM is not clearly established. The aim of this study was to determine the incidence of DGE in patients with and without DM after PD. Methods: The American College of Surgeons National Quality Improvement Project (ACS-NSQIP) procedure-targeted pancreatectomy database was queried from 2014 to 2017 for patients undergoing PD and combined with the main ACS-NSQIP database. Patient demographic, clinical and perioperative variables were compared by DM status. The primary outcome was rate of DGE. A subset analysis of insulin-dependent DM (IDDM) and non-insulin-dependent DM (non-IDDM) patients was also performed. Statistical analyses were performed using chi-square, Mann Whitney-U tests, and logistic regression. Results: A total of 14,735 patients met inclusion criteria, including 10,930 non-DM patients (74.2%) and 3805 DM patients (25.8%). Median cohort age was 66 years and 53.7% were male (n=7918). DGE occurred in 17.1% of patients overall (n=2519); 17.2% in non-DM and 16.8% in DM patients (p=0.60). DM patients had a higher ASA class, increased rates of hypertension, increased proportion of pancreatic adenocarcinoma, larger duct size, harder gland texture, and required more frequent vascular resection (p<0.001). DM patients had equivalent rates compared to non-DM patients of post-operative superficial surgical site infection (7.8% in both; p=0.89), deep surgical site infection (1.4 vs 1.5%; p=0.56), urinary tract infection (3.2 vs 2.8%; p=0.23) and pneumonia (4.3 vs 3.6%; p=0.19), and lower rates of organ space infection (11.5 vs 14.0%; p<0.001) and pancreatic fistula (14.9 vs 19.0%; p<0.001). On subset analysis, IDDM had better outcomes compared to non-IDDM patients in organ space infections (8.8 vs 14.2%; p<0.001) and pancreatic fistula (11.7 vs 18.3%; p<0.001). Rates of DGE were 18.0% (n=337) in non-IDDM and 15.7% in IDDM patients (p=0.162). There were no significant differences in rates of reoperation, hospital length of stay, readmission rates or 30-day mortality. On multivariable logistic regression, male sex, advanced age, history of smoking, pancreatic fistula, and organ space infection were associated with DGE. DM status was not predictive of DGE. Conclusion: No differences in rates of DGE between DM and non-DM patients after PD were found, strengthening the hypothesis that DGE is a separate physiologic entity from diabetic gastroparesis. IDDM patients demonstrated better postsurgical outcomes compared to non-IDDM patients in terms of intra-abdominal infection and pancreatic fistula, suggesting a potential role of monitored insulin or hyperglycemia regulation in the development of these complications.

Chronic Illness and Self-Care Management. A Perspective of Diabetic Patients

Increasing the quality of life and life expectancy of patients at acceptable levels requires the study of the ethical dimension of medical care. The research aims at understanding the social construction of chronic illness from the patient's perspective, taking into account the perspective of patients - chronic diabetic - on the significance of the chronic illness they suffer from, and the dimensions of self-care management. The research is based on a secondary analysis of data, focus groups and interviews with insulin-dependent diabetes mellitus patients. The condition of chronic illness requires the patient to have a certain awareness - the disease as a life situation, the limitations that arise due to the chronic disease status, the lifestyle and the quality of the illness that arise from the disease. The chronic patient experiences the chronic condition, as the normality of his life, as what defines him or will define him his whole life.

Impact of diabetes mellitus on surgical complications in patients undergoing revision total knee arthroplasty: Insulin dependence makes a difference

ObjectivesAssessing the effects of diabetes mellitus (DM), non-insulin-dependent diabetes mellitus (NIDDM), and insulin-dependent diabetes mellitus (IDDM) on revision TKA (rTKA) has become increasingly imperative due to the increased rates of revisions associated with DM. This study sought to identify complications in rTKA that were independently associated with NIDDM/IDDM compared to non-diabetic (Non-DM) patients and whether IDDM was associated with specific postoperative complications compared to NIDDM. Methods and materials16,428 rTKA patients were identified from the ACS-NSQIP database from 2005 to 2016 and stratified into three separate cohorts. 12,922 (78.66%) were Non-DM, 2335 (14.21%) had NIDDM, and 1171 (7.13%) had IDDM. Univariate analyses were utilized to assess for differences in demographics, preoperative comorbidities, and postoperative complication rates. Multivariate logistic regression analyses were then employed to control for significant differences in patients characteristics to assess NIDDM and IDDM as independent risk factors for complications in comparison to Non-DM. IDDM was further analyzed as a risk factor in comparison to NIDDM for the purpose of elucidating the impact of insulin dependence on risk for postoperative complications. ResultsNIDDM was an independent risk factor for deep incisional surgical site infections (Odds Ratio (OR): 2.477) and urinary tract infections (UTI) (OR 1.862) (p < 0.05). Compared to NIDDM, IDDM was independently associated with greater risk for pneumonia (OR 2.603), septic shock (OR 6.597), blood transfusions (OR 1.326), and an extended length of stay (OR: 1.331) (p < 0.05). IDDM additionally increased the risk for acute renal failure (OR 3.269) and cardiac arrest (OR 3.268) (p < 0.05) when compared to Non-DM. DM patients overall had increased rates of worse outcomes and infectious complications. ConclusionAlthough differences between diabetes and non-diabetes rTKA patients were seen, differences in complication rates between diabetes patients further divided based on insulin dependence status were also noted. Future work examining whether targeting perioperative glucose levels <200 mg/dL in DM rTKA patients decreases infectious complications is warranted. Future work analyzing the role of tranexamic acid administration and 24-h postoperative antibiotics in rTKA IDDM patients may be warranted given the elevated risk of pneumonia, septic shock, and blood transfusions.

Insulin Dependence Is Associated With Increased Medical Complications and Mortality After Shoulder Arthroscopy

To compare complications after shoulder arthroscopy in patients with insulin-dependent diabetes mellitus (IDDM), patients with non-insulin-dependent diabetes mellitus (NIDDM), and nondiabetic patients. A retrospective analysis of the American College of Surgeons National Surgical Quality Improvement Program database for the years 2005 to 2016 was conducted. Logistic regression analyses were used to assess the relation between diabetic status (nondiabetic patients, n= 50,626; NIDDM patients, n= 5,332; and IDDM patients, n= 2,484) and outcomes. Multivariate models were established to adjust for age, sex, body mass index, hypertension, congestive heart failure, chronic obstructive pulmonary disease, smoking status, American Society of Anesthesiologists classification, and functional status. Patients with IDDM were at a higher risk of medical complications, with an adjusted odds ratio (AOR) of 1.524 (95% confidence interval [CI], 1.082-2.147), including pulmonary complications (AOR, 2.078; 95% CI, 1.089-3.964) and urinary tract infections (AOR, 2.129; 95% CI, 1.027-4.415). Patients with IDDM also had a higher risk of 30-day hospital admission (AOR, 1.581; 95% CI, 1.153-2.169) and 30-day mortality (AOR, 3.821; 95% CI, 1.243-11.750). Conversely, patients with NIDDM had comparable risks of medical and surgical complications, unplanned hospital admission, and death to nondiabetic patients. Medical complications, 30-day hospital admission, and death after shoulder arthroscopy were more likely in patients with IDDM. These risks diminished among patients with NIDDM, with their risks being comparable with those of nondiabetic patients. Level III, retrospective comparison study.

Preparation of Immunotolerant Space Under the Skin and Transplantation of Islets in the Space.

Although transplantation of islets of Langerhans has been accepted as a fundamental treatment for insulin-dependent diabetes mellitus (IDDM), several problems are still remaining in order that it becomes the standard medical treatment of IDDM patients. In this study, using diabetic rat models, a subcutaneous space surrounded with highly vascularized granulomatous tissue was formed by agarose-bFGF rod implantation. Allogeneic islets transplanted into the space could survive and release insulin for a long period under no immunosuppressive medication. In conjunction with sufficient supply of islets from iPS/ES cells, our method can make islet transplantation the standard medical treatment of IDDM patients.

Diabetes Mellitus as a Risk Factor for Acute Postoperative Complications Following Elective Adult Spinal Deformity Surgery.

Study Design:Retrospective cohort study.Objectives:Diabetes mellitus is a highly prevalent disease in the United States. Adult spinal deformity (ASD) surgery encompasses a wide variety of spinal disorders and is associated with a morbidity rate between 20% and 80%. Considering utilization of spinal surgery will continue to increase, this study investigates the influence of diabetes mellitus on acute postoperative outcomes following elective ASD surgery.Methods:The 2010-2014 American College of Surgeon’s National Surgical Quality Improvement Program database was queried using Current Procedural Terminology and International Classification of Diseases (9th Revision) diagnosis codes relevant to ASD surgery. Patients were divided into cohorts based on their diabetic status. Bivariate and multivariate logistic regression analyses were employed to identify which 30-day postoperative outcomes patients are at risk for.Results:A total of 5809 patients met the inclusion criteria for the study of which 4553 (84.2%) patients were nondiabetic, 578 (10.7%) patients had non–insulin-dependent diabetes mellitus (NIDDM), and 275 (5.1%) patients had insulin-dependent diabetes mellitus (IDDM). Diabetes status was significantly associated with length of stay ≥5 days (NIDDM: odds ratio [OR] = 1.27, 95% confidence interval [CI] = 1.02-1.58, P = .034; IDDM: OR = 1.55, 95% CI = 1.15-2.09, P = .004), any complication (NIDDM: OR = 1.26, 95% CI = 1.01-1.58, P = .037), urinary tract infection (NIDDM: OR = 1.87, 95% CI = 1.14-3.05, P = .012), and cardiac complications (IDDM: OR = 4.05, 95% CI = 1.72-9.51, P = .001).Conclusions:Given the prevalence of diabetes, surgeons will invariably encounter these patients for ASD surgery. The present study identifies the increased risk NIDDM and IDDM patients experience following ASD surgery. Quantification of this increased risk may improve the selection of appropriate surgical candidates, patient risk stratification, and patient postoperative safety.

Women with Type 1 Diabetes Mellitus: Effect of Disease and Psychosocial-Related Correlates on Health-Related Quality of Life.

Background This study is aimed at investigating the various disease-specific and health-related psychosocial concepts of HRQOL among insulin-dependent diabetes mellitus (IDDM) and understanding the gender differences in HRQOL among IDDM patients. Methods A cross-sectional observational study was conducted to assess the effect of health-related and psychosocial correlates on HRQOL of IDDM patients in Penang, Malaysia. The participants were recruited from five governmental diabetic clinics. Patients with insulin use only, IDDM diagnosed at least 1 year earlier, were identified from clinical registers. The sample was then age stratified for 20–64 years, and severe complications (e.g., end-stage renal failure, hemodialysis, and liver cirrhosis) were excluded; a total of 1003 participants were enrolled in the study. Multivariate regression analysis was used to predict the response. Results A total of 853 (100%) participants were enrolled and completed the study. Women exhibited significantly higher/better mental health (p < 0.013) and health perception scores (p < 0.001) despite high prevalence of impaired role (49.2%), social (24.2%), and physical (40.5%) functionings as compared to men. Women with longer diabetes exposure and uncontrolled glycemic levels (HbA1c) have poorer HRQOL. Availability of social support showed no significant association with either HRQOL or diabetes distress levels. Diabetes distress levels remained not associated with social support. Women also showed significantly higher association with health perception (15% versus 13% men, p < 0.001) and mental health (13% versus 11% men, p < 0.001) in diabetes-specific psychosocial factors. Thus, among women alone, diabetes-related specific and psychosocial factors explained 15% and 13% of variations in HRQOL extents, respectively. Conclusion Women exhibit extensive and significant patterns with health-related factors and diabetes-specific psychosocial factors (self-efficacy, social support, and DLC) to improve HRQOL. Also, women have significantly high reported distress levels and low social functioning compared to men.

Salivary and Serum Aspartate Aminotransferases and Alanine Aminotransferases in Insulin-Dependent Diabetes Mellitus and Normal Children: A Comparative Study.

Aims and Objectives:The aim of the study was to estimate and compare aspartate aminotransferases (AST) and alanine aminotransferases (ALT) levels in saliva and serum of insulin-dependent diabetes mellitus (IDDM) and normal children, and the objective was to evaluate the significance of these enzymes in assessing the salivary gland injury in IDDM children.Materials and Methods:The study group comprised of thirty children clinically and biochemically diagnosed for IDDM and thirty healthy children of similar age in the control group. Saliva and serum samples were collected and enzyme assay was performed by optimized ultraviolet test method (according to International Federation of Clinical Chemistry). The values obtained were subjected to statistical analysis using Mann–Whitney U-test for comparison of the variables and Karl–Pearson's coefficient test for correlation. The SPSS 16.0, (SPSS Inc., Chicago, USA) was used for statistical analysis.Results:Higher values of AST (mean = saliva 91.60 IU/L) and ALT (mean = saliva 94.93 IU/L) were found in the saliva than in serum (AST serum = 15.83 IU/L) (ALT serum = 20.80 IU/L) among the patients and the differences were statistically highly significant (P = 0.001). A similar comparison in the control group did not show statistical significant difference (saliva – AST mean = 23.50 IU/L, ALT mean = 21.95 IU/L and serum – AST mean = 12.60 IU/L, ALT mean = 13.25 IU/L). On correlation between patient and normal group, greater values of AST and ALT were observed in saliva of patients and the difference was statistically highly significant ([AST-mean = patients 91.166 IU/L and controls = 23.500 IU/L] [ALT-mean = patients 94.933 IU/L and controls 21.950 IU/L]). The serum values of patients and controls did not show statistical difference. Although higher values of salivary ALT and AST were observed in patients with the disease for 0–5-year clinical duration (ALT mean = 100.21 IU/L and AST mean = 95.39 IU/L) than those with the disease for 6–10-year duration (ALT mean = 77.57 IU/L and AST mean = 77.28 IU/L), values were statistically nonsignificant.Conclusion:Elevated salivary AST and ALT levels in IDDM patients suggest the injury to salivary glands and could aid as a salivary marker for the involvement of salivary glands in IDDM.

The impact of insulin dependence on short-term postoperative complications in diabetic patients undergoing total shoulder arthroplasty

The number of total shoulder arthroplasty (TSA) procedures performed is steadily increasing, and it is important to characterize predictors of postoperative complications for risk assessment models. Whereas diabetes has been associated with increased morbidity after TSA, the impact of insulin dependence on the risk profile of diabetic patients has not been described. The National Surgical Quality Improvement Program database from 2011-2014 was used to identify 5918 TSA cases. Patients were categorized as non-diabetes mellitus (non-DM), non-insulin-dependent diabetes mellitus (NIDDM), or insulin-dependent diabetes mellitus (IDDM). Thirty-day postoperative complication rates, length of stay (LOS), and readmission rates were compared across the diabetes groups. Multivariable logistic regression adjusting for demographics and comorbidity burden was performed to determine the independent association between insulin dependence and postoperative outcomes. In bivariate analysis, NIDDM and IDDM were associated with multiple postoperative complications, including stroke, sepsis, wound complications, blood transfusion, and extended LOS. With multivariable logistic regression, however, NIDDM patients did not have significantly greater odds of any study end point relative to non-DM patients. IDDM patients had significantly greater odds for having any postoperative complication (odds ratio [OR], 1.53), stroke (OR, 13.63), blood transfusion (OR, 1.67), and extended LOS (OR, 1.38). After adjustment for demographics and comorbidity burden, NIDDM patients had risk profiles similar to those of non-DM patients. IDDM was an independent predictor of multiple postoperative complications. Insulin dependence should be considered in the preoperative risk assessment of diabetic patients undergoing TSA.

Supporting decisions in diabetic patients management through case-based retrieval.

In this paper we present a tool for the intelligent retrieval of past cases to support Insulin Dependent Diabetes Mellitus patients therapy revision. This tool was designed for assisting physicians during periodical monitoring visits. Each case is represented through i) a collection of features that describe the patient's clinical state at the decision time, i.e. the control visit, ii) the decision taken in terms of therapy revision and iii) the outcome obtained on the metabolic control during the following monitoring period. A new case is first classified into a protypical monitoring situation, and then similar cases are retrieved and shown to the user. This tool is fully integrated in a Web-based distributed system for Diabetes Management, developed within in the EU project T-IDDM.

Behaviour of Fetal Haemoglobin and Its Correlation to Haemoglobin A1c Levels in Sudanese Adult Insulin-Dependent Diabetes Mellitus Patients

Abstract 10390: Impact of Diabetes Mellitus on the Prognosis of Patients With Heart Failure and Preserved Left Ventricle Ejection Fraction: Insights From the TOPCAT Study

Background: The impact of diabetes mellitus (DM) for patients with heart failure and preserved left ventricle ejection fraction (HFpEF) remains unclear. We aimed to determine the impact of DM on the prognosis of patients with DM and HFpEF enrolled in the TOPCAT trial. Methods: We classified TOPCAT patients into three groups: insulin-dependent DM (IDDM), non-insulin dependent DM (NIDDM) and non-DM. We investigated the occurrence of a major adverse cardiovascular event (MACE), defined as CV mortality, hospitalization for HF, non-fatal myocardial infarction (MI), non-fatal non-hemorrhagic stroke, or aborted cardiac arrest. Secondary outcomes included the individual components of MACE and all-cause mortality. We used multivariate Cox proportional hazards regression models to evaluate the independent associations of DM on time to MACE. Results: There were 1,134 DM patients (439 IDDM and 695 NIDDM) and 2,307 non-DM patients. The IDDM patients were younger and more likely to be male, non-white, and from the Americas. Despite having the highest median left ventricle’s ejection fraction (LVEF) (58%) compared to NIDDM and non-DM patients (57% and 56%, respectively, p=0.007), they were more symptomatic. Forty-eight percent of IDDM patients were of New York Heart Association (NYHA) III/IV functional classes compared to 36% of NIDDM and 29% of non-DM patients (p&lt;0.001). IDDM patients had significantly increased risks for MACE, CV mortality, MI, HF hospitalization, and all-cause mortality when compared to non-DM patients (p-values&lt;0.01). NIDDM patients had similar risks for MACE and the secondary outcomes as the non-DM patients. The effect of diabetes on outcomes was similar between regions. Conclusion: Among HFpEF patients, IDDM but not NIDDM was independently associated with increased risks of MACEs. Future research is needed to evaluate whether optimal medications and lifestyle interventions may reduce MACE in these high-risk patients.

Insulin dependence as an independent predictor of perioperative morbidity after ventral hernia repair: a National Surgical Quality Improvement Program analysis of 45,759 patients

BackgroundAlthough diabetes mellitus has been identified as a predictor of perioperative morbidity after ventral hernia repair (VHR), it is unclear whether insulin-dependent diabetes mellitus (IDDM) and non–insulin-dependent diabetes mellitus (NIDDM) confer the same degree of risk. We examined the variable effect of IDDM and NIDDM on 30-day medical and surgical complications after VHR. MethodsWe performed a retrospective analysis of patients in the National Surgical Quality Improvement Program database from 2005 to 2012 undergoing VHR. After perioperative variable comparison, regression analysis was performed to determine whether IDDM and/or NIDDM independently predicted increased complications after proper risk adjustment. ResultsA total of 45,759 patients were identified to have undergone VHR. Of these, 38,026 patients (83.1%) were not diabetic, 5,252 (11.5%) were NIDDM patients, and 2,481 (5.4%) were IDDM patients. After controlling for other risk factors, we found that IDDM independently predicted increased rates of overall, surgical, and medical complications (odds ratio, 1.284, 1.251, 1.263, respectively) in open repair. IDDM independently predicted increased overall and medical complications (odds ratio, 1.997, 1.889, respectively) but not surgical complications in laparoscopic repair. NIDDM was not significantly associated with any complication type in either procedure type. ConclusionsOur present study suggests that much of the perioperative risk associated with diabetes is attributable to IDDM. The effect of IDDM on laparoscopic and open repair is subtly different. IDDM demonstrates increased overall and medical complications in laparoscopic repair and increased overall, medical, and surgical complications in open repair. Of note, IDDM does not independently predict increased risk for surgical complications in laparoscopic repair.

The impact of diabetes mellitus on outcomes of endoscopic sinus surgery: a nested case‐control study

Given the immune impairment associated with diabetes mellitus (DM), its impact on chronic rhinosinusitis (CRS) is a potentially relevant concern; however, it has not been well-studied. A single retrospective study reported worse postoperative quality of life outcomes in DM patients with CRS. Our study evaluated the effect of comorbid DM on outcomes of endoscopic sinus surgery (ESS) using a prospective study design. Using a multicentered, prospective cohort of patients (n = 437) undergoing ESS for recalcitrant CRS, a nested case-control comparison was performed between 20 adult DM patients (cases) and 20 non-DM patients (controls), matched 1:1 for age and Lund-Mackay computed tomography (CT) scores. Outcome measures included 22-item Sinonasal Outcome Test (SNOT-22), Rhinosinusitis Disability Index (RSDI), Patient Health Questionnaire (PHQ-2), and Brief Smell Identification Test (BSIT). Mean follow-up was similar between cases (mean ± standard deviation: 12.6 ± 6.0 months) and controls (12.9 ± 5.9 months; p = 0.862). All preoperative scores were statistically equivalent between DM and non-DM cohorts. Both cohorts showed significant post-ESS improvement in SNOT-22 (p = 0.001) and RSDI scores (p < 0.001), and no significant change in PHQ-2 or BSIT scores. The magnitude of score changes was statistically equivalent between the 2 cohorts for all outcome measures with no differences in postoperative score changes between insulin-dependent DM patients and those managed by oral hypoglycemics or dietary restriction (p ≥ 0.444). DM patients with CRS experience similar degrees of symptomatic benefit from ESS compared to controls. Insulin dependence does not appear to adversely affect surgical outcome but a larger cohort would better assess the effect of DM type and control on surgical outcomes in CRS.

Similar Outcome in Insulin-Dependent and Noninsulin-Dependent Diabetic Patients After Off-Pump Coronary Artery Bypass Grafting With Multiple Skeletonized Arterial Conduits

We were interested in whether current multiarterial off-pump coronary artery bypass graft surgery can improve the clinical outcome for insulin-dependent diabetes mellitus patients. Between January 2002 and December 2013, 1,064 consecutive patients underwent isolated off-pump coronary artery bypass surgery at our hospital; 551 of these patients had diabetes. Of these 551 patients, 166 had insulin-dependent diabetes (IDM) and the remaining 385 had noninsulin-dependent diabetes (NIDM). The propensity score was calculated to achieve one-to-two matching sets (IDM 143 versus NIDM 286). Ten patients (3.5%) in the NIDM group and 2 patients (1.4%) in the IDM group died in hospital (p = 0.18). Insulin dependency was not an independent risk factor for any early death or major complications. Follow-up was complete for 96.5% of the patients, with a mean follow-up of 4.6 ± 3.8 years. Overall survival rate at 10 years was 76.3% for the NIDM group and 73.1% for the IDM group (p = 0.79). The rate of 10-year actuarial freedom from major adverse cardiac events was 89.6% in the NIDM group and 86.3% in the IDM group (p = 0.72). Multivariate Cox proportional hazard regression analysis revealed that female sex, congestive heart failure, previous myocardial infarction, lower ejection fraction, and at least one major complication were independent risk factors for combined cardiac events. Insulin dependency did not affect any outcome in the long term. Early and long-term outcomes after off-pump skeletonized multiarterial coronary artery bypass graft surgery were similar among the IDM and NIDM patients.

Drug-eluting stents with biodegradable polymer for the treatment of patients with diabetes mellitus: clinical outcome at 2 years in a large population of patients.

ObjectiveThis study investigates the safety and efficacy of a third-generation drug-eluting stent (DES) with biodegradable polymer in the complex patient population of diabetes mellitus (DM).Clinical trial registrationISRCTN81649913.BackgroundPercutaneous coronary interventions in patients with DM are associated with a higher incidence of death, restenosis, and stent thrombosis as compared to non-diabetic patients. The use of a DES has been shown to improve outcomes in diabetic patients.MethodsOut of 3,067 patients, enrolled in 126 centers worldwide in the NOBORI 2 registry, 888 patients suffered from DM, 213 of them (14%) being insulin-dependent DM (IDDM). Two years’ follow-up has been completed in this study.ResultsAt 1- and 2-year follow-up, 97% and 95% of the patients, respectively, were available. The reported target lesion failure (TLF) rates at 1- and 2-year follow-up were 6.0% and 7.2% in the DM group, respectively, and 3.0% and 4.2% in the non-DM group, respectively (P<0.001 for both years). Inside the DM group, the TLF rates of 9.9% and 11.7% at the 1- and 2-year follow-ups, respectively, in patients with IDDM were significantly higher than the TLF rates of 4.7% and 5.8%, respectively, in the non-IDDM subgroup (P<0.01 for both years). The rate of stent thrombosis at the 2-year follow-up was 1.0% in the DM group and 0.7% in non-DM patients. There were no cases of late, or very late stent thrombosis in IDDM patients.ConclusionThe Nobori DES performed well in patients with DM. As expected, patients with DM, particularly those with IDDM, had worse outcomes. However, the absence of late, and very late stent thrombosis in IDDM patients merits further investigation, as this finding might have significant clinical value.
