The relative associations of β-cell function and insulin sensitivity with glycemic status and incident glycemic progression in migrant Asian Indians in the United States: The MASALA study

AimsWe assessed the relative associations of β-cell dysfunction and insulin sensitivity with baseline glycemic status and incident glycemic progression among Asian Indians in the United States.MethodsA 5-sample oral glucose tolerance test was obtained at baseline. Normoglycemia, impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and type 2 diabetes (T2DM) were defined by ADA criteria. The Matsuda Index (ISI_M) estimated insulin sensitivity, and the Disposition Index (DI_o) estimated β-cell function. Visceral fat was measured by abdominal CT. After 2.5 years, participants underwent a 2-sample oral glucose tolerance test. Standardized polytomous logistic regression was used to examine associations with prevalent and incident glycemia.ResultsMean age was 57 ± 8 years and BMI 26.1 ± 4.6 kg/m². Log ISI_M and log DI_o were associated with prediabetes and T2DM after adjusting for age, sex, BMI, family history of diabetes, hypertension, and smoking. After adjusting for visceral fat, only DI_o remained associated with prediabetes (OR per SD 0.17, 95% CI: 0.70, 0.41) and T2DM (OR 0.003, 95% CI: 0.0001, 0.03). Incidence rates (per 1,000 person-years) were: normoglycemia to IGT: 82.0, 95% CI (40, 150); to IFG: 8.4, 95% CI (0, 41); to T2DM: 8.6, 95% CI (0, 42); IGT to T2DM: 55.0, 95% CI (17, 132); IFG to T2DM: 64.0, 95% CI (3, 316). The interaction between sex and the change in waist circumference (OR 1.8, per SD 95% CI: 1.22, 2.70) and the change in log HOMA-β (OR 0.37, per SD 95% CI: 0.17, 0.81) were associated with glycemic progression.ConclusionsThe association of DI_o with baseline glycemia after accounting for visceral fat as well as the association of the change in log HOMA-β with incident glycemic progression implies innate β-cell susceptibility in Asian Indians for glucose intolerance or dysglycemia.     

Synergistic increase risk of death and myocardial infarction at one year in patients with concomitant diabetes mellitus and renal failure

AimsWe tested the hypothesis that in patients with acute myocardial infarction (AMI), concomitant diabetes mellitus (DM) and renal failure (RF) increases the short- and long-term risk compared to DM or RF alone.Materials and methodsThis registry included consecutive patients with AMI treated with percutaneous coronary intervention (PCI) who completed 1-year follow-up. The primary outcome included the rate of all causes of death, AMI, and target vessel revascularization (TVR).ResultsA total of 858 patients were studied in 4 groups: DM and RF, 112 (13.1%); DM alone, 145 (16.9%); RF alone, 134 (15.6%); and no DM or RF, 467 (54.4%). The DM and RF group had more cardiogenic shock, lower ejection fraction, longer hospital stay, and higher peak troponin (all p < 0.01). After multivariable adjusted analysis, the DM and RF group had higher risk of death (HR 3.35, CI 1.69–6.67; p < 0.01), AMI (HR 2.8; CI 1.15–6.83; p = 0.02), and major adverse cardiac events (HR 1.97, CI 1.23–3.13; p < 0.01) at 1-year follow-up compared to patients with no DM or RF.ConclusionThe combination of DM and RF is the strongest independent predictor of death and AMI, but not a predictor of TVR. These findings should be evaluated in large prospective studies.     

Risk factors for foot ulcers—A cross sectional survey from a primary care setting in Brazil

AimsTo identify the prevalence of higher risk of foot ulceration and associated factors among patients with diabetes mellitus (DM) at primary health care services.MethodsIndividuals with DM, registered at primary health care services in a municipality in southern Brazil, were interviewed and underwent foot examinations. Their risk of ulceration was classified in accordance with the recommendations of the International Working Group on the Diabetic Foot. Poisson bivariate and multivariate analyses were performed and adjusted prevalence ratios (PR) and 95% confidence intervals (CI) were calculated.ResultsThe prevalence of higher risk of foot ulceration among the 337 interviewees was 27.9% (95% CI 23.1–32.9). The following factors were associated with this risk: having been diagnosed with DM for more than 10 years (Adjusted-PR 1.669; 95% CI 1.175–2.373; p = 0.004); having had previous diagnoses of acute myocardial infarction (Adjusted-PR 1.873; 95% CI 1.330–2.638; p < 0.001) and stroke (Adjusted-PR 1.684; 95% CI 1.089–2.604; p = 0.019); presenting interdigital mycosis (Adjusted-PR 1.539; 95% CI 1.030–2.300; p = 0.035) and calluses (Adjusted-PR 1.654; 95% CI 1.117–2.451; p = 0.012).ConclusionsThe prevalence of higher risk of ulceration was high, which reinforces the importance of continued education for health care professionals in order to prevent complications in the feet of these patients.     

Body mass index and all-cause mortality among type 2 diabetes mellitus patients: Findings from the 5-year follow-up of the MADIABETES cohort

PurposeTo analyse the association between body mass index (BMI) and all-cause mortality in a 5-year follow-up study with Spanish type 2 diabetes mellitus (T2DM) patients, seeking gender differences.Methods3443 T2DM outpatients were studied. At baseline and annually, patients were subjected to anamnesis, a physical examination, and biochemical tests. Data about demographic and clinical characteristics was also recorded, as was the treatment each patient had been prescribed. Mortality records were obtained from the Spanish National Institute of Statistics. Survival curves for BMI categories (Gehan-Wilcoxon test) and a multivariate Cox proportional hazard analysis were performed to identify adjusted Hazard Ratios (HRs) of mortality.ResultsMortality rate was 26.38 cases per 1000 patient-years (95% CI, 23.92–29.01), with higher rates in men (28.43 per 1000 patient-years; 95% CI, 24.87–32.36) than in women (24.31 per 1000 patient-years; 95% CI, 21.02–27.98) (p = 0.079). Mortality rates according to BMI categories were: 56.7 (95% CI, 40.8–76.6), 28.4 (95% CI, 22.9–34.9), 24.8 (95% CI, 21.5–28.5), 21 (95% CI, 16.3–26.6) and 23.7 (95% CI, 14.3–37) per 1000 person-years for participants with a BMI of < 23, 23–26.8, 26.9–33.1, 33.2–39.4, and > 39.4 kg/m², respectively. The BMI values associated with the highest all-cause mortality were < 23 kg/m², but only in males [HR: 2.78 (95% CI, 1.72–4.49; p < 0.001)], since in females this association was not significant [HR: 1.14 (95% CI, 0.64–2.04; p = 0.666)] (reference category for BMI: 23.0–26.8 kg/m²). Higher BMIs were not associated with higher mortality rates.ConclusionsIn an outpatient T2DM Mediterranean population sample, low BMI predicted all-cause mortality only in males.     

Contribution of common variants of ENPP1, IGF2BP2, KCNJ11, MLXIPL,PPARγ, SLC30A8 and TCF7L2 to the risk of type 2 diabetes in Lebanese and Tunisian Arabs

BackgroundWhile several type 2 diabetes mellitus (T2DM) susceptibility loci identified through genome-wide association studies (GWAS) have been replicated in many populations, their association in Arabs has not been reported. For this reason, the present study looked at the contribution of ENNP1 (rs1044498), IGF2BP2 (rs1470579), KCNJ11 (rs5219), MLXIPL (rs7800944), PPARγ (rs1801282), SLC30A8 (rs13266634) and TCF7L2 (rs7903146) SNPs to the risk of T2DM in Lebanese and Tunisian Arabs.MethodsStudy subjects (case/controls) were Lebanese (751/918) and Tunisians (1470/838). Genotyping was carried out by the allelic discrimination method.ResultsIn Lebanese and Tunisians, neither ENNP1 nor MLXIPL was associated with T2DM, whereas TCF7L2 was significantly associated with an increased risk of T2DM in both the Lebanese [P < 0.001; OR (95% CI): 1.38 (1.20–1.59)] and Tunisians [P < 0.001; OR (95% CI): 1.36 (1.18–1.56)]. Differential associations of IGF2BP2, KCNJ11, PPARγ and SLC30A8 with T2DM were noted in the two populations. IGF2BP2 [P = 1.3 × 10^?5; OR (95% CI): 1.66 (1.42–1.94)] and PPARγ [P = 0.005; OR (95% CI): 1.41 (1.10–1.80)] were associated with T2DM in the Lebanese, but not Tunisians, while KCNJ11 [P = 8.0 × 10^?4; OR (95% CI): 1.27 (1.09–1.47)] and SLC30A8 [P = 1.6 × 10^?5; OR (95% CI): 1.37 (1.15–1.62)] were associated with T2DM in the Tunisians, but not Lebanese, after adjusting for gender and body mass index.ConclusionT2DM susceptibility loci SNPs identified through GWAS showed differential associations with T2DM in two Arab populations, thus further confirming the ethnic contributions of these variants to T2DM susceptibility.     

Pregnancy complications,mental health-related problems and type 2 diabetes mellitus in Malaysian women

AimsThe aim of this study was to investigate the association between pregnancy complications, mental health-related problems, and type 2 diabetes mellitus (T2DM) in Malaysian women.Materials and methodsA case–control study of women with T2DM (n = 160) matched by age range to controls without T2DM (n = 160). Data were collected in the Negeri Sembilan and PutraJaya regions in Malaysia, from two hospital outpatient clinics, PutraJaya Hospital and Tuanku Jaa’far Hospital Seremban, and one health clinic at Seremban. Validated, interviewer-administered questionnaires were used to obtain the data. The unadjusted and adjusted estimates were calculated using the Mantel–Haenszel method.ResultsNeither depression (RR 0.74, 95% CI: 0.39–1.41) nor anxiety (RR 1.00, 95% CI: 0.53–1.88) symptoms increased the risk of T2DM significantly. However, gestational diabetes (RR 1.35, 95% CI: 1.02–1.79), and ≥3 pregnancies (RR 1.39, 95% CI: 1.08–1.79) were significant risk factors for the development of T2DM. T2DM was not a significant risk factor for either depression (RR 1.26, 95% CI: 0.91–1.74) or anxiety symptoms (RR 1.13, 95% CI: 0.59–2.19).ConclusionIn this study, T2DM is not a significant risk factor for depression and anxiety; similarly, neither are depression and anxiety significant risk factors for T2DM. Although prevalence of depression and anxiety is not alarming, the findings reported here should alert clinicians to screen and treat anxiety and depression in people with diabetes and also note the importance of monitoring women with complications in pregnancy for risk of later T2DM.     

Characteristics of co-infections by HCV and HBV among Brazilian patients infected by HIV-1 and/or HTLV-1

BackgroundThe human retroviruses HIV-1 and HTLV-1 share the routes of infection with hepatitis viruses B and C. Co-infection by these agents are a common event, but we have scarce knowledge on co-infection by two or more of these agents.ObjectiveTo evaluate the characteristics and risk factors for co-infections by HBV and HCV in patients infected by HIV-1 or/and HTLV-1, in Salvador, Brazil.MethodsIn a case–control study we evaluated patients followed in the AIDS and HTLV clinics of Federal University of Bahia Hospital. Clinical and epidemiological characteristics were reviewed, and patients were tested for the presence of serological markers of HBV and HCV infections. HCV-infected patients were tested by PCR to evaluate the presence of viremia.ResultsA total of 200 HIV-1, 213 HTLV-1-infected, and 38 HIV-HTLV-co-infected individuals were included. HIV-infected patients were more likely to have had more sexual partners in the lifetime than other patients’ groups. HIV-HTLV-co-infected subjects were predominantly male. Patients infected by HTLV or co-infected had a significantly higher frequency of previous syphilis or gonorrhea, while HIV infection was mainly associated with HPV infection. Co-infection was significantly associated to intravenous drug use (IVDU). HBV and/or HCV markers were more frequently found among co-infected patients. HBV markers were more frequently detected among HIV-infected patients, while HCV was clearly associated with IVDU across all groups. AgHBs was strongly associated with co-infection by HIV-HTLV (OR = 22.03, 95% CI: 2.69–469.7), as well as confirmed HCV infection (p = 0.001). Concomitant HCV and HBV infection was also associated with retroviral co-infection. Patients infected by HTLV-1 had a lower chance of detectable HCV viremia (OR = 0.04, 95% CI: 0.002–0.85).ConclusionsInfection by HCV and/or HBV is frequent among patients presenting retroviral infection, but risk factors and prevalence for each infection are distinct for each agent. Retroviral co-infection increases the risk of a positive AgHBs, but HTLV-1 infection seems to increase the likelihood of HCV spontaneous clearance.     

Prolongation of the heart rate-corrected QT interval is associated with cardiovascular diseases: Systematic review and meta-analysis

BackgroundConflicting findings have described the association between prolonged heart rate-corrected QT interval (QTc) and cardiovascular disease.AimsTo identify articles investigating the association between QTc and cardiovascular disease morbidity and mortality, and to summarize the available evidence for the general and type 2 diabetes populations.MethodsA systematic search was performed in PubMed and Embase in May 2022 to identify studies that investigated the association between QTc prolongation and cardiovascular disease in both the general and type 2 diabetes populations. Screening, full-text assessment, data extraction and risk of bias assessment were performed independently by two reviewers. Effect estimates were pooled across studies using random-effect models.ResultsOf the 59 studies included, 36 qualified for meta-analysis. Meta-analysis of the general population studies showed a significant association for: overall cardiovascular disease (fatal and non-fatal) (hazard ratio [HR] 1.68, 95% confidence interval [CI] 1.33–2.12; I² = 69%); coronary heart disease (fatal and non-fatal) in women (HR 1.27, 95% CI 1.08–1.50; I² = 38%; coronary heart disease (fatal and non-fatal) in men (HR 2.07, 95% CI 1.26–3.39; I² = 78%); stroke (HR 1.59, 95% CI 1.29–1.96; I² = 45%); sudden cardiac death (HR 1.60, 95% CI 1.14–2.25; I² = 68%); and atrial fibrillation (HR 1.55, 95% CI 1.31–1.83; I² = 0.0%). No significant association was found for cardiovascular disease in the type 2 diabetes population.ConclusionQTc prolongation was associated with risk of cardiovascular disease in the general population, but not in the type 2 diabetes population.     

Tenofovir,entecavir, and lamivudine in patients with severe acute exacerbation and hepatic decompensation of chronic hepatitis B

ObjectiveTo compare the efficacy of and mortality after lamivudine (LAM), tenofovir (TDF), and entecavir (ETV) treatment in patients with severe acute chronic hepatitis B (CHB) exacerbation.MethodsWe analyzed 91 patients with severe acute CHB exacerbation treated with LAM (n = 28), TDF (n = 26), or ETV (n = 37) for 10 years. The primary endpoint was overall mortality or liver transplantation (LT) by 48 weeks. The determined predictors of mortality, virologic and biochemical responses, and drug resistance were also evaluated.ResultsThe overall mortality or LT rate was not significantly different among the LAM (14.3%), ETV (10.8%), and TDF (3.8%) groups (P = 0.435). In the multivariate analysis, the occurrence of ascites (hazard ratio [HR] 10.467, 95% confidence interval [CI] 1.596–68.645, P = 0.014) and model for end-stage liver disease (MELD) scores above 25 (HR 28.920, CI 4.719-177.251, P = 0.000) increased the risk of mortality or LT. All groups showed similar biochemical responses (P = 0.134), virologic responses (HBV DNA <116 copies/mL, P = 0.151), and HBeAg seroconversion (P = 0.560). Antiviral resistance emerged in five patients treated with LAM by 48 weeks (17.9%, P = 0.003).ConclusionLAM, ETV, and TDF selection is not related with mortality and LT in patients with severe acute CHB exacerbation and hepatic decompensation. To reduce mortality, patients with ascites and MELD scores above 25 should be considered for LT.     

Metformin and risk of cancer among patients with type 2 diabetes mellitus: A systematic review and meta-analysis

AimWe carried out this meta-analysis on all published studies to estimate the overall cancer risk of the use of metformin in T2DM patients.MethodsWe searched the PubMed, Embase and CNKI databases for all articles within a range of published years from 2007 to 2019 on the association between the use of metformin and cancer risk in T2DM patients. The odds ratio (OR) corresponding to the 95% confidence interval (95% CI) was used to assess the association using a random-effect meta-analysis.ResultsFinally, 67 studies met the inclusion criteria for this study, with 10,695,875 T2DM patients and 145,108 cancer cases. Overall, For T2DM patients of ever vs. never metformin users, there was statistical evidence of significantly decreased cancer risk was found to be associated with ever metformin users (OR = 0.70, 95% CI = 0.65–0.76). Considering T2DM may be a specific and independent risk factor for various forms of cancer, due to its particular metabolic characteristics of glucose intolerance and hyperinsulinemia, we performed a comparison to estimate the effects of metformin on cancer risk with other anti-diabetes medications (ADMs), our results found significantly decreased cancer risk to be associated with the use of metformin (OR = 0.80, 95% CI = 0.73–0.87).ConclusionOur meta-analysis indicated that metformin may be a independent protective factor for cancer risk in T2DM patients.     

Derivation and validation of the prediabetes self-assessment screening score after acute pancreatitis (PERSEUS)

Background and aimApproximately 40% of patients develop abnormal glucose metabolism after a single episode of acute pancreatitis. This study aimed to develop and validate a prediabetes self-assessment screening score for patients after acute pancreatitis.MethodsData from non-overlapping training (n = 82) and validation (n = 80) cohorts were analysed. Univariate logistic and linear regression identified variables associated with prediabetes after acute pancreatitis. Multivariate logistic regression developed the score, ranging from 0 to 215. The area under the receiver-operating characteristic curve (AUROC), Hosmer–Lemeshow χ² statistic, and calibration plots were used to assess model discrimination and calibration. The developed score was validated using data from the validation cohort.ResultsThe score had an AUROC of 0.88 (95% CI, 0.80–0.97) and Hosmer–Lemeshow χ² statistic of 5.75 (p = 0.676). Patients with a score of ≥75 had a 94.1% probability of having prediabetes, and were 29 times more likely to have prediabetes than those with a score of <75. The AUROC in the validation cohort was 0.81 (95% CI, 0.70–0.92) and the Hosmer–Lemeshow χ² statistic was 5.50 (p = 0.599). Model calibration of the score showed good calibration in both cohorts.ConclusionThe developed and validated score, called PERSEUS, is the first instrument to identify individuals who are at high risk of developing abnormal glucose metabolism following an episode of acute pancreatitis.     

Acute kidney injury after allogeneic hematopoietic stem cell transplantation – Predictors and survival impact: A single center retrospective study

Introduction and objectivesAcute kidney injury (AKI) is a frequent complication of hematopoietic stem cell transplantation (HSCT) and appears to be linked to increased morbidity and mortality. The aim of this study was to evaluate the incidence, etiology, predictors and survival impact of early AKI in the post-allogeneic HSCT setting.Patients and methodsWe performed a retrospective single center study that included 155 allogeneic transplant procedures from June 2017 through September 2019.ResultsAKI was observed in 50 patients (32%). In multivariate analysis, age (OR 31.55, 95% CI [3.42; 290.80], p = 0.002), evidence of disease at the time of transplant (OR 2.54, 95% CI [1.12; 5.75], p = 0.025), cytomegalovirus reactivation (OR 5.77, 95% CI [2.43; 13.72], p < 0.001) and hospital stay >35 days (OR 2.66, 95% CI [1.08; 6.52], p = 0.033) were independent predictors for AKI. Increasing age (HR 1.02, 95% CI [1.00; 1.04], p = 0.029), increasing length of hospital stay (HR 1.02, 95% CI [1.01; 1.03], p = 0.002), matched unrelated reduced intensity conditioning HSCT (HR 1.91, 95% CI [1.10; 3.33], p = 0.022), occurrence of grade III/IV acute graft-versus-host disease (HR 2.41, 95% CI [1.15; 5.03], p = 0.019) and need for mechanical ventilation (HR 3.49, 95% CI [1.54; 7.92], p = 0.003) predicted an inferior survival in multivariate analysis. Early AKI from any etiology was not related to worse survival.ConclusionPatients submitted to HSCT are at an increased risk for AKI, which etiology is often multifactorial. Due to AKI incidence, specialized nephrologist consultation as part of the multidisciplinary team might be of benefit.     

All-cause mortality in patients with diabetes under glucagon-like peptide-1 agonists: A population-based,open cohort study

AimThe glucagon-like peptide-1 receptor agonist (GLP1a) liraglutide has been described to benefit patients with type 2 diabetes mellitus (T2DM) at high cardiovascular risk. However, there are still uncertainties relating to these cardiovascular benefits: whether they also apply to an unselected diabetic population that includes low-risk patients, represent a class-effect, and could be observed in a real-world setting.MethodsWe conducted a population-based, retrospective open cohort study using data derived from The Health Improvement Network database between Jan 2008 to Sept 2015. Patients with T2DM exposed to GLP1a (n = 8345) were compared to age, gender, body mass index, duration of T2DM and smoking status-matched patients with T2DM unexposed to GLP1a (n = 16,541).ResultsPatients with diabetes receiving GLP1a were significantly less likely to die from any cause compared to matched control patients with diabetes (adjusted incidence rate ratio [aIRR]: 0.64, 95% CI: 0.56–0.74, P-value < 0.0001). Similar findings were observed in low-risk patients (aIRR: 0.64, 95% CI: 0.53–0.76, P -value = 0.0001). No significant difference in the risk of incident CVD was detected in the low-risk patients (aIRR: 0.93, 95% CI: 0.83–1.12). Subgroup analyses suggested that effect is persistent in the elderly or across glycated haemoglobin categories.ConclusionsGLP1a treatment in a real-world setting may confer additional mortality benefit in patients with T2DM irrespective of their baseline CVD risk, age or baseline glycated haemoglobin and was sustained over the observation period.     

Time to antibiotics administration and outcome in community-acquired pneumonia: Secondary analysis of a randomized controlled trial

BackgroundThe association between early antibiotic administration and outcomes remains controversial in patients hospitalized for community-acquired pneumonia.MethodsWe performed a secondary analysis of a randomized controlled trial comparing two antibiotic treatment strategies for patients hospitalized for moderately severe CAP. The univariate and multivariate associations between time to antibiotic administration (TTA) and time to clinical stability were assessed using a Cox proportional hazard model. Secondary outcomes were death, intensive care unit admission and hospital readmission up to 90 days.Results371 patients (mean age 76 years, CURB-65 score ≥ 2 in 52%) were included. Mean TTA was 4.35 h (SD 3.48), with 58.5% of patients receiving the first antibiotic dose within 4 h.In multivariate analysis, number of symptoms and signs (HR 0.876, 95% CI 0.784–0.979, p = 0.020), age (HR 0.986, 95% CI 0.975–0.996, p = 0.007), initial heart rate (HR 0.992, 95% CI 0.986–0.999, p = 0.023), and platelets count (HR 0.998, 95% CI 0.996–0.999, p = 0.004) were associated with a reduced probability of reaching clinical stability. The association between TTA and time to clinical stability was not significant (HR 1.009, 95% CI 0.977–1.042, p = 0.574). We found no association between TTA and the risk of intensive care unit admission, death or readmission up to 90 days after the initial admission.ConclusionIn patients hospitalized for moderately severe CAP, a shorter time to antibiotic administration was not associated with a favorable outcome. These findings support the current recommendations that do not assign a specific time frame for antibiotics administration.     

Variants within the calpain-10 gene and relationships with type 2 diabetes (T2DM) and T2DM-related traits among Tunisian Arabs

BackgroundCommon variations in the calpain 10 (CAPN10) gene variants UCSNP-43, UCSNP-19 and UCSNP-63, and the 112/121 diplotype, are associated with an increased risk of type 2 diabetes (T2DM) and T2DM-related traits.MethodsThe association of UCSNP-43, -19 and -63 CAPN10 SNPs with T2DM was assessed in 917 Tunisian T2DM patients and 748 ethnically matched non-diabetic controls. CAPN10 genotyping was done by PCR-RFLP.ResultsSignificant differences in UCSNP-19 MAF, but not UCSNP-43 or -63, and genotype distribution were seen between patients and controls. Heterogeneity in UCSNP-19, but not UCSNP-43 and -63, genotype distribution was noted according to geographical origin. Obesity was associated with UCSNP-19, while raised fasting glucose was associated with UCSNP-63, and increased HDL was associated with UCSNP-43. Enrichment of homozygous UCSNP-19 2/2 was seen in overweight and obese compared with lean patients; logistic-regression analyses demonstrated a positive association of the 2/2 genotype with overweight [P = 0.003; OR (95% CI) = 2.07 (1.28–3.33)] and obese [P = 0.021; OR (95% CI) = 1.83 (1.10–3.07)] patients. Of the six CAPN10 haplotypes identified, significant enrichment of only haplotype 111 was seen in T2DM patients [Pc = 0.034; OR (95% CI) = 1.22 (1.06–1.41)], while the frequency of all identified CAPN10 diplotypes, including the high-risk 112/121, was comparable between patients and controls.ConclusionWhile CAPN10 UCSNP-19 SNP and haplotype 111 contribute to the risk of T2DM in Tunisian subjects, no significant association between CAPN10 diplotypes and T2DM was demonstrated.     

Complicaciones asociadas a la hiperglucemia en pacientes trasplantados de hígado

BackgroundHyperglycemia is a frequent phenomenon in hospitalized patients that is associated with negative outcomes. It is common in liver transplant patients as a result of stress and is related to immunosuppressant drugs. Although studies are few, a history of diabetes and the presentation of hyperglycemia during liver transplantation have been associated with a higher risk for rejection.AimsTo analyze whether hyperglycemia during the first 48 hours after liver transplantation was associated with a higher risk for infection, rejection, or longer hospital stay.MethodsA retrospective cohort study was conducted on patients above the age of 15 years that received a liver transplant. Hyperglycemia was defined as a value above 140 mg/dl and it was measured in three different manners (as an isolated value, as a mean value, and as a weighted value over time). The relation of hyperglycemia to a risk for acute rejection, infection, or longer hospital stay was evaluated.ResultsSome form of hyperglycemia was present in 94% of the patients during the first 48 post-transplantation hours, regardless of its definition. There was no increased risk for rejection (OR: 1.49; 95% CI: 0.55-4.05), infection (OR: 0.62; 95% CI: 0.16-2.25), or longer hospital stay between the patients that presented with hyperglycemia and those that did not.ConclusionsHyperglycemia during the first 48 hours after transplantation appeared to be an expected phenomenon in the majority of patients and was not associated with a greater risk for rejection or infection and it had no impact on the duration of hospital stay.     

Efecto pronóstico diferencial de la diabetes mellitus tipo 2 en mujeres y varones con insuficiencia cardiaca y fracción de eyección conservada

Introduction and objectivesType 2 diabetes mellitus (DM2) is a common comorbidity in patients with heart failure (HF) with preserved ejection fraction (HFpEF). Previous studies have shown that diabetic women are at higher risk of developing HF than men. However, the long-term prognosis of diabetic HFpEF patients by sex has not been extensively explored. In this study, we aimed to evaluate the differential impact of DM2 on all-cause mortality in men vs women with HFpEF after admission for acute HF.MethodsWe prospectively included 1019 consecutive HFpEF patients discharged after admission for acute HF in a single tertiary referral hospital. Multivariate Cox regression analysis was used to evaluate the interaction between sex and DM2 regarding the risk of long-term all-cause mortality. Risk estimates were calculated as hazard ratios (HR).ResultsThe mean age of the cohort was 75.6 ± 9.5 years and 609 (59.8%) were women. The proportion of DM2 was similar between sexes (45.1% vs 49.1%, P = .211). At a median (interquartile range) follow-up of 3.6 (1-4-6.8) years, 646 (63.4%) patients died. After adjustment for risk factors, comorbidities, biomarkers, echo parameters and treatment at discharge, multivariate analysis showed a differential prognostic effect of DM2 (P value for interaction = .007). DM2 was associated with a higher risk of all-cause mortality in women (HR, 1.77; 95%CI, 1.41-2.21; P < .001) but not in men (HR, 1.23; 95%CI, 0.94-1.61; P = .127).ConclusionsAfter an episode of acute HF in HFpEF patients, DM2 confers a higher risk of mortality in women. Further studies evaluating the impact of DM2 in women with HFpEF are warranted.Full English text available from:www.revespcardiol.org/en     

Efficacy of tumour necrosis factor antagonists in stricturing Crohn’s disease: A tertiary center real-life experience

BackgroundStenosis is the most common complication of Crohn’s disease (CD). Long-term outcome of patients receiving tumour necrosis factor (TNF) antagonists for such disease complication is poorly understood.Methods51 CD patients (from July 2006 to November 2015) who had a diagnosis of small bowel or colonic stenosis, diagnosed by colonoscopy and/or MRI enterography, and were treated with TNF antagonists (adalimumab or infliximab) were enrolled.The primary outcome was to assess the rate of success of TNF antagonists on avoiding abdominal surgery for stricturing CD patients.Results20 patients (39.2%) underwent surgery during the follow-up period. The overall incidence of abdominal surgery was 1.8 per 100 person-months at risk, while the median time to surgery was 37.9 months. The univariable and multivariable Cox’s proportional hazards analysis of baseline parameters indicated that disease location (colonic vs ileal, HR: 28.2, 95% CI: 2.45–324, p = 0.007; ileocolonic vs ileal, HR: 3.38, 95% CI: 1.09–10.5, p = 0.035), prestenotic dilatation (per 1-mm increase, HR: 1.08, 95% CI: 1.01–1.15, p = 0.022) and the existence of non-perianal fistula (HR: 9.77, 95% CI: 2.99–31.9, p < 0.001) are independent risk factors for abdominal surgery.ConclusionsIn stricturing CD, anti-TNFs are effective in up to about two-thirds of the patients.     

Risk factors for development and progression of nonproliferative retinopathy in normoalbuminuric patients with type 1 diabetes

BackgroundThe aim of this study was to evaluate risk factors for development and progression of nonproliferative retinopathy (NPR) in normoalbuminuric patients with type 1 diabetes mellitus (T1DM).MethodsA total of 223 T1DM with normal renal function and normoalbuminuria were included in this study and followed for 48 months. Photodocumented retinopathy status was made according to the EURODIAB protocol. Urinary albumin excretion rate (UAE) was measured from at least two 24-h urine samples. Possible risk factors for development or progression of NPR were examined in backward stepwise Cox's multiple regression analysis.ResultsThe majority of patients (70%) had no retinopathy while 67 (30%) had NPR at baseline. Patients with NPR were older, had longer duration of diabetes, higher systolic blood pressure, BMI, resting heart rate, UAE and lower estimated glomerular filtration rate (p ≤ 0.04 for all). After 48 months 24 patients (10.7%) developed NPR or progressed to proliferative retinopathy. Systolic blood pressure (HR 1.03, CI 1.01–1.05, p = 0.02), UAE (HR 1.14, CI 1.07–1.21, p < 0.001), and resting heart rate (HR 1.05, CI 1.01–1.09, p = 0.006) were significantly associated with development or progression of NPR.ConclusionsOur results suggest that retinopathy is present and may progress in T1DM even when coexisting renal disease is excluded. Normoalbuminuric T1DM requires close monitoring for the early detection of retinopathy, especially if they have a higher UAE, systolic blood pressure and resting heart rate.
