Anemia in Patients With Diabetes and Prediabetes With Normal Kidney Function: Prevalence and Clinical Outcomes

ObjectiveAnemia is a known complication of diabetes mellitus (DM); however, its prevalence and prognostic relevance in patients with DM and pre-DM with normal kidney function have not been well defined. This study assessed the prevalence of anemia in patients with DM and pre-DM and evaluated its association with clinical outcomes during a 4-year follow-up period.MethodsThis retrospective analysis included patients with DM and pre-DM referred to the Meir Medical Center Endocrine Institute in 2015. Patients with an estimated glomerular filtration rate (eGFR) of <60 mL/min or any other recognized cause of anemia were excluded. The risk of developing microvascular or macrovascular complications or of death during the 4-year follow-up period was determined.ResultsA total of 622 patients (408 with DM and 214 with pre-DM) were included. The mean age of the patients was 64 ± 10.6 years, and 70% were women. The baseline hemoglobin A1C level was 7.1% ± 1.7% (54 mmol/mol), and the eGFR was 86.1 ± 15.3 mL/min. At the time of inclusion, 77 patients (19%) with DM and 23 (11%) with pre-DM had anemia (hemoglobin level 11.9 ± 0.8 and 11.8 ± 0.8 g/dL, respectively), compared with normal hemoglobin levels of 13.8 ± 0.9 and 13.7± 0.9 g/dL, respectively, in the others. A multivariable analysis demonstrated an inverse correlation between baseline hemoglobin (as a continuous variable) and mortality (P = .035), microvascular complications (P = .003), and eGFR decline (P < .001) but not between baseline hemoglobin and macrovascular complications (P = .567).ConclusionThis study found a significant prevalence of anemia unrelated to renal failure, both in patients with DM and pre-DM. Anemia in these patients is associated with the development of microvascular complications, eGFR decline, and mortality. These results underscore the need for intensive lifestyle and pharmacologic interventions in these patients.     

Comparison of Profile of Primary Hyperparathyroidism With and Without Type 2 Diabetes Mellitus: Retrospective Analysis From the Indian Primary Hyperparathyroidism Registry

ObjectiveTo describe the prevalence and compare the clinicobiochemical profile of patients with primary hyperparathyroidism (PHPT) with and without type 2 diabetes mellitus (T2DM).MethodsWe conducted a retrospective observational study wherein the details of patients with PHPT with T2DM (PHPT-T2DM) and without T2DM were retrieved from the Indian PHPT Registry (www.indianphptregistry.com) between 2005 and 2019. We compared the clinical, biochemical, and postoperative findings of patients with PHPT-T2DM with age-, sex-, and body mass index–matched patients with PHPT without T2DM (in 1:2 ratio).ResultsOf the 464 patients with PHPT, 54 (11.6%) had T2DM. We observed an increase in the prevalence of PHPT-T2DM cases over time; only 7 (7.1%) of the total patients with PHPT had T2DM between 2005 and 2009 that increased to 31 (12.8%) in the last half decade (2015-2019). Patients with PHPT-T2DM had a significantly lower prevalence of nephrolithiasis (18.5% vs 36.1%, respectively; P = .03) and a higher prevalence of pancreatitis (22.2% vs 5.6%, respectively; P = .007) than those without T2DM. Furthermore, intact parathyroid hormone (203 pg/mL [139.8-437.3 pg/mL] vs 285 pg/mL [166-692 pg/mL], respectively; P = .04) and serum creatinine (0.90 mg/dL [0.67-1.25 mg/dL] vs 1.10 mg/dL [0.73-1.68 mg/dL], respectively; P = .03) levels were significantly lower in patients with PHPT-T2DM than those without T2DM. Also, tumor weight tended to be lower in patients with PHPT-T2DM than in the non-T2DM counterparts (1.05 g [0.5-2.93 g] vs 2.16 g [0.81-7.0 g], respectively; P = .06).ConclusionThe prevalence of T2DM in Asian Indians with PHPT is 11.6%. Patients with PHPT-T2DM are characterized by a higher prevalence of pancreatitis, a lower prevalence of nephrolithiasis, and lower levels of intact parathyroid hormone/creatinine. Part of the clinical picture can possibly be explained by early detection of PHPT in patients with T2DM consequent to more frequent screening.     

SARS-CoV-2 Seroprevalence in Individuals With Type 1 and Type 2 Diabetes Compared With Controls

ObjectiveData for the association between diabetes and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) susceptibility are conflicting. We aimed to evaluate this association using an analytical cross-sectional study design.MethodsStudy participants were recruited from endocrine clinics of our hospital and belonged to 3 groups: group 1 (type 1 diabetes mellitus [T1DM]), group 2 (type 2 diabetes mellitus [T2DM]), and group 3 (controls). All participants submitted blood samples for SARS-CoV-2 S1/S2 immunoglobulin G antibody test (LIAISON; DiaSorin) and were interviewed for a history of documented infection.ResultsWe evaluated a total of 643 participants (T1DM, 149; T2DM, 160; control, 334; mean age, 37.9 ± 11.5 years). A total of 324 (50.4%) participants were seropositive for SARS-CoV-2. The seropositivity rate was significantly higher in the T1DM (55.7% vs 44.9%, P = .028) and T2DM (56.9% vs 44.9%, P = .013) groups than in the control group. The antibody levels in seropositive participants with T1DM and T2DM were not significantly different from those in seropositive controls. On multivariable analysis, low education status (odds ratio [OR], 1.41 [95% CI, 1.03-1.94]; P = .035), diabetes (OR, 1.68 [95% CI, 1.20-2.34]; P = .002), and overweight/obesity (OR, 1.52 [95% CI, 1.10-2.10]; P = .012) showed a significant association with SARS-CoV-2 seropositivity. The association between diabetes and SARS-CoV-2 seropositivity was found to further increase in participants with coexisting overweight/obesity (adjusted OR, 2.63 [95% CI, 1.54-4.47]; P < .001).ConclusionSARS-CoV-2 seropositivity, assessed before the onset of the national vaccination program, was significantly higher in participants with T1DM and T2DM than in controls. The antibody response did not differ between seropositive participants with and without diabetes. These findings point toward an increased SARS-CoV-2 susceptibility for patients with diabetes, in general, without any differential effect of the diabetes type.     

Decreased Mortality After Long-Term Treatment With Dipeptidyl Peptidase-4 Inhibitors: A Retrospective Study of U.S. Veterans With Type 2 Diabetes

ObjectiveThe prevalence of chronic kidney disease (CKD) in the United States is 13% of the general population. Among those with CKD, diabetic nephropathy is the leading cause of end-stage renal disease. This is a retrospective study examining the effect of long-term use of dipeptidyl peptidase-4 (DPP-4) inhibitors on all-cause mortality and progression of renal disease in the veteran population.MethodsData was extracted using the Veterans Administration Informatics and Computing Infrastructure. A large cohort of veterans diagnosed with type 2 diabetes mellitus were used to identify patients on DPP-4 inhibitors and without DPP-4 inhibitors. Groups were compared to determine the effect of DPP-4 inhibitors on the progression of CKD and all-cause mortality. Data were analyzed using SAS.ResultsSubjects in the treatment group (n = 40 558) had baseline variables (age, body mass index, race) similar to the control group (n = 40 558). Diabetes control improved in the treatment group (HgbA1c, 8.3% [67 mmol/mol] to 7.8% [62 mmol/mol]; P < .001) but not in the control group (HgbA1c, 7.4% [57 mmol/mol] to 7.3% [56 mmol/mol]). New diagnoses of heart failure and coronary artery bypass grafts were clinically significant (odds ratios = 0.66 and 0.52). No change in progression of CKD was seen in either group. All-cause mortality was reduced by 59%.ConclusionWe conclude that DPP-4 inhibitors are associated with a significant reduction in all-cause mortality independent of glucose control, albeit with no clear cause, including obtainable cardiovascular outcomes. Our data is consistent with prior trials in that DPP-4 inhibitors did not show a significant change in serum creatinine or microalbuminuria.     

Pragmatic Clinic-Based Investigation of Glycemic Variability in Patients With Type 1 Diabetes in Routine Clinical Practice and Its Association With Cardiovascular Autonomic Neuropathy: A Pilot Study

ObjectiveTo evaluate the relationship between markers of glycemic variability (GV), assessed by blinded continuous glucose monitoring (CGM), and cardiovascular autonomic neuropathy (CAN) in patients with type 1 diabetes (T1D).MethodsGV indices, such as SD and coefficient of variation were obtained by blinded CGM through an electrode inserted into the subcutaneous tissue for at least 3 consecutive days. CAN was assessed by cardiovascular reflex tests and HRV.ResultsFifteen T1D patients were included: 7 (46.7%) women, aged 47.1 ± 11.6 years, with a diabetes duration of 26 years (20 to 29.5 years). Five patients (25%) were excluded from our study. The majority of our patients presented glycated hemoglobin (60%), SD (86.3%), and coefficient of variation (60%) above the established goals. Patients with defined CAN had a longer diabetes duration, higher glycated hemoglobin levels, lower glomerular filtration rate, lower prevalence of indices related to hypoglycemic stress, and short-term GV indices compared with patients without CAN.ConclusionOur study showed an inverse association between GV and CAN. The most important risk factors associated with CAN were age, diabetes duration, and markers of chronic hyperglycemia. Furthermore, the difficulty in the interpretation of data extracted from the blinded CGM system, which also requires a minimum of 3 capillary blood glucose measurements for calibration, should be carefully analyzed to ensure the accuracy and usefulness of the blinded CGM system as a tool for diabetes management in developing countries. Further studies are necessary to establish the role of GV in the development of CAN in patients with T1D.     

Factors Associated With Insulin Pump Discontinuation in Adults With Diabetes: A Time-to-Invent Analysis and Prediction Model

ObjectiveInsulin pump discontinuation has mostly been studied in children and adolescents living with diabetes. We aimed to assess the rate of insulin pump continuation in a population of adult patients with diabetes, at 18 months after initiation; determine the factors associated with pump discontinuation; and develop a simple prediction model.MethodsThis single-center, retrospective study included all adult patients with type 1 diabetes or type 2 diabetes who started insulin pump treatment between January 2015 and June 2018. The exclusion criteria were pregnancy, short-term pregnancy plans, and insulin pump discontinuation within the previous 6 months. The probability of insulin pump continuation after 18 months was estimated using the Kaplan-Meier method. Factors associated with insulin pump discontinuation were studied using a Cox regression model, and an exponential model was built for prediction purposes.ResultsThe study included 315 patients. The mean age was 41 years, the mean duration of diabetes was 16 years, 50% were men, 74% had type 1 diabetes, and the mean hemoglobin A1c level was 9.1% (76 mmol/mol). After 18 months, the rate of insulin pump continuation was 0.80 (95% Confidence Interval (CI), 0.76-0.85). By multivariate analysis, the occurrence of severe hypoglycemia in the previous year was associated with insulin pump discontinuation (hazard ratio, 2.42; 95% CI, 1.30-4.51), while other factors did not reach statistical significance.ConclusionInsulin pump discontinuation occurred in 20% of patients at 18 months after initiation and was mainly associated with a recent history of severe hypoglycemia. The type of diabetes and glycemic control at baseline were not associated with treatment discontinuation.     

Effect of Treatment of OSA With CPAP on Glycemic Control in Adults With Type 2 Diabetes: The Diabetes Sleep Treatment Trial (DSTT)

ObjectiveThe effect of obstructive sleep apnea (OSA) treatment with continuous positive airway pressure (CPAP) on glycemic measures in patients with type 2 diabetes (T2D) remains unclear. We aimed to determine whether CPAP treatment of OSA improves glycemic measures in patients with T2D.MethodsThis randomized controlled trial (N = 98) examined changes in glycemic measures following 12 weeks of active (n = 49) or sham (n = 49) CPAP and consideried participants’ adherence to CPAP therapy (percentage of days with ≥4 hours use and average hours/day of use).ResultsBaseline treatment groups were similar. Regarding the efficacy of active vs sham-CPAP over time, at 6 weeks, both groups had similar reductions in fructosamine (mean difference [MD], 95% confidence interval [CI]: CPAP ?13.10 [?25.49 to ?0.7] vs. sham ?7.26 [?20.2 to 5.69]; P = .519) but different in HbA1c (CPAP ?0.24 [?0.48 to ?0.003] vs sham 0.15 [?0.10 to 0.4]; P = .027). At 12 weeks, reductions in HbA1c values were similar by group (CPAP ?0.26 [?0.53 to 0.002] vs sham ?0.24 [?0.53 to 0.04]; P = .924). HbA1c reductions were associated with a greater percentage of cumulative days of CPAP usage ≥4 hours per day (b [SE] = 0.006 [0.002]; P = .013) and cumulative hours of CPAP use (b [SE] = 0.08 [0.08]; P = .012). CPAP use of ≥7 hours was associated with a significant reduction in HbA1c (b [SE] 0.54 [0.16]; P = .0012).ConclusionCPAP treatment of OSA did not result in sustained improved glycemic control compared to sham in the intent-to-treat analysis. CPAP adherence was associated with greater improvements in glycemic control.     

Sex-Specific Associations Between Diabetes Mellitus and Hearing Loss in the Middle-Aged and Elderly Individuals: A National Cohort Study of Chinese Adults

ObjectiveTo examine the association between diabetes and hearing loss and whether the association varied by sex.MethodsThis cohort study based on nationally representative data from the China Health and Retirement Longitudinal Study included 16 140 Chinese adults aged >45 years between 2011 and 2018. Diabetes was identified by blood glucose levels, HbA1c levels, and a self-reported diagnosis at baseline. The main outcome was self-reported incident hearing loss. Cox proportional hazards regression models were performed to estimate the risk of hearing loss.ResultsWe documented 2388 cases of hearing loss during a median 6.9 years of follow-up. The incidence rates were 29.64 (95% CI, 28.07-31.29) per 1000 person-years in women and 25.23 (95% CI, 23.77-26.78) per 1000 person-years in men. After adjustment, the hazard ratios of hearing loss associated with diabetes were 1.20 (95% CI, 1.01-1.42) for women and 0.97 (95% CI, 0.78-1.19) for men. Compared with poor control of the blood sugar levels, the odds ratio for hearing loss for women with good glycemic control was reduced from 5.08 (95% CI, 1.31-19.66) to 1.26 (95% CI, 0.69-2.28), and the corresponding odds ratio for men was 1.65 (95% CI, 0.61-4.44) to 0.50 (95% CI, 0.18-1.38).ConclusionIn conclusion, we identified a differential effect of sex on hearing loss risk with more pronounced effects for women. Our data suggest that good blood glucose level control is helpful to prevent hearing loss.     

Comparison of Carotid Intima-Media Thickness in Children and Adults With and Without Obesity: A Hysteresis Model

ObjectiveTo describe a third-degree polynomial function (hysteresis) of the effect size of age, obesity, and insulin sensitivity over the carotid intima-media thickness (c-IMT), in the pediatric and adult groups.MethodsA quasi-experimental study with fixed factor analysis of age (children aged 8-12 years, n = 73; adults aged 21-45 years, n = 82) and obesity (yes, n = 76; no, n = 79) was conducted to analyze the effect on the c-IMT and Matsuda insulin sensitivity index values. This quasi-experimental design was analyzed with robust regression modeling.ResultsThe additive effect of obesity, independent of age, was evident in the case of the c-IMT values. There was no interaction effect, but a significant difference between participants with normal weight and those with obesity was found (P < .0001). The difference between adults and children was also significant, but the effect size was smaller. A model was created based on age, Tanner stage, and obesity using the c-IMT and Matsuda insulin sensitivity index values. A linear function fit as R², and the cubic function estimated parameters like a polynomial model.ConclusionThis practical study design showed that children with obesity displayed the same levels of carotid intima-media abnormalities as adults with obesity. The polynomial shape of the model suggests potentially poor outcomes that resemble the hysteresis process and may predict chronic cardiometabolic events during early adulthood.     

Basal Insulin Degludec and Glycemic Control Compared to Aspart Via Insulin Pump in Type 1 Diabetes (BIGLEAP): A Single-Center,Open-Label,Randomized, Crossover Trial

ObjectiveWe compared the efficacy of the second-generation basal insulin degludec (IDeg) to that of insulin aspart via pump using continuous glucose monitoring in patients with well-controlled type 1 diabetes.MethodsIn this 40-week, single-center, randomized, crossover-controlled trial, adults with well-controlled type 1 diabetes (hemoglobin A1C of <7.5% [<58 mmol/mol]) (N = 52) who were using an insulin pump and continuous glucose monitoring were randomized to 1 of 2 treatments for a 20-week period: a single daily injection of IDeg with bolus aspart via pump or a continuous subcutaneous insulin infusion (CSII) with aspart, followed by crossover to the other treatment. The primary endpoint was time in range (70-180 mg/dL) during the final 2 weeks of each treatment period.ResultsFifty-two patients were randomized and completed both treatment periods. The time in range for IDeg and CSII was 71.5% and 70.9%, respectively (P = .553). The time in level 1 hypoglycemia for the 24-hour period with IDeg and CSII was 2.19% and 1.75%, respectively (P = .065). The time in level 2 hypoglycemia for the 24-hour period with IDeg and CSII was 0.355% and 0.271%, respectively (P = .212), and the nocturnal period was 0.330% and 0.381%, respectively (P = .639). The mean standard deviation of blood glucose levels for the 24-hour period for IDeg and CSII was 52.4 mg/dL and 51.0 mg/dL, respectively (P = .294). The final hemoglobin A1C level for each treatment was 7.04% (53 mmol/mol) with IDeg, and 6.95% (52 mmol/mol) with CSII (P = .288). Adverse events were similar between treatments.ConclusionWe observed similar glycemic control between IDeg and insulin aspart via CSII for basal insulin coverage in patients with well-controlled type 1 diabetes.     

Sex-Specific Associations of Iron-Anemia Status With Hemoglobin A1C Levels Among Hispanics/Latinos Without Self-Reported Diabetes Mellitus: The Hispanic Community Health Study/Study of Latinos

ObjectiveThe objective of this study was to examine the sex-specific associations of mutually exclusive iron-anemia status categories with hemoglobin A1C (HbA1C) levels among U.S. Hispanics/Latinos without self-reported diabetes mellitus.MethodsBaseline cross-sectional data (7247 women and 4904 men without self-reported diabetes mellitus) from the Hispanic Community Health Study/Study of Latinos were analyzed. Per the American Diabetes Association’s defined criteria, based on HbA1C levels, the participants were categorized as having normoglycemia, prediabetes, or probable diabetes mellitus. The iron-anemia status categories were as follows: no anemia and no iron deficiency (reference), iron deficiency, iron deficiency anemia (IDA), and non-iron deficiency anemia (non-IDA). Survey multinomial logistic regression models were used to examine the sex-specific associations of iron-anemia status with HbA1C levels after adjusting for sociodemographic, lifestyle, and clinical factors.ResultsThe age-standardized prevalence of iron-anemia status categories differed by sex. Compared with those with no anemia and no iron deficiency and normoglycemia, women with IDA had higher odds of having prediabetes (odds ratio [OR], 2.18; 95% CI, 1.64-2.89) and probable diabetes mellitus (OR, 3.59; 95% CI, 1.62-7.99) based on HbA1C levels; men with non-IDA had higher odds of having probable diabetes mellitus (OR, 2.97; 95% CI, 1.13-7.78) based on HbA1C levels. All other associations did not reach statistical significance.ConclusionAmong U.S. Hispanics/Latinos without self-reported diabetes mellitus, the age-standardized prevalence of iron deficiency, IDA, and non-IDA is high and varies by sex. Women with IDA had higher odds of having prediabetes and probable diabetes mellitus, defined based on HbA1C levels. Men with non-IDA had higher odds of having probable diabetes mellitus, defined based on HbA1C levels. Iron-anemia status should be considered while interpreting elevated HbA1C levels among U.S. Hispanics/Latinos without self-reported diabetes mellitus.     

The Risk Factors for Developing Clustered Vertebral Compression Fractures: A Single-Center Study

ObjectiveVertebral compression fractures (VCFs) are common among elderly individuals, but clustered VCFs (C-VCFs) are rare and more severe. The risk factors for C-VCFs remain unclear. Thus, we investigated the clinical characteristics of C-VCFs to identify the imminent fracture risk and improve the treatment for such patients.MethodsWe reviewed the records of patients with VCF at a single medical center between January 2011 and September 2020. Patients who had 4 or more VCFs within 1 year were categorized into the C-VCF group, and the remaining patients were paired into the control group at a ratio of 2:1. We collected demographic, clinical, laboratory, and radiologic information regarding these patients. Univariate analyses, stratified analyses, and multivariate logistic regression were performed to identify the risk factors for C-VCFs.ResultsA total of 156 patients were enrolled, of whom 52 were patients with C-VCF. Patients with C-VCF had more severe fractures and pain, with fractures occurring at uncommon sites of the spine. The independent risk factors for C-VCFs included glucocorticoid (GC) treatment (P < .001; hazard ratio [HR], 12.7), recent fracture history (P = .021; HR, 5.5), and lower trabecular bone score (TBS) (P = .044; HR, 1.6). TBS and bone mineral density had greater predictive values in patients without GC treatment (P < .001). Sex, age, and bone turnover biomarkers were not independent risk factors for C-VCFs.ConclusionC-VCFs are rare adverse consequences of severe osteoporosis, for which GC treatment, recent fracture history, and lower TBS are unique risk factors that are valuable for the early identification and prevention of C-VCFs.     

Validation of Diagnostic Coding for Diabetes Mellitus in Hospitalized Patients

ObjectiveSome studies have shown that there is an undercoding of diabetes mellitus among hospitalized patients, which can have adverse clinical and financial implications for health systems. We aimed to validate the discharge diagnostic coding of diabetes mellitus in hospitalized patients using clinical and laboratory-based diagnostic indicators as the reference.MethodsThis was a retrospective cohort study of 83 690 discharges of 48 615 unique adult patients who were hospitalized in an academic medical center over 4.5 years and had at least 4 blood glucose measurements during admission. A missing diabetes code (MDC) was defined using 2 criteria. MDC₁ was defined as the presence of any of the following: blood glucose ≥200 (x2), A1C ≥6.5%, home antihyperglycemic medication, or preadmission code for diabetes, whereas MDC₂ was defined as preadmission diabetes or at least 2 other criteria in MDC₁. Multivariable logistic regression was used to identify factors associated with MDC compared to the present diabetes code.ResultsMDC₁ and MDC₂ were present in 12 186 (14.6%) and 3542 (4.7%) discharges, respectively. Factors associated with both MDC₁ and MDC₂ were medium-dose steroid use [adjusted odds ratio (aOR) 2.11, 2.01], high-dose steroid use (aOR 4.70, 2.50), intermediate medical care service (aOR 1.65, 1.55), infection (aOR 1.21, 1.34), and hepatic disease (aOR 1.93, 1.92).ConclusionIn this retrospective study, MDC ranged from 5% to 15% and was associated with various clinical factors. Further prospective studies are needed to validate these findings, explore the mechanisms behind these associations, and understand the clinical and financial implications.     

Long-Term Prognosis of Acute Myocardial Infarction Associated With Metabolic Health and Obesity Status

ObjectiveEmerging evidence supports the favorable cardiovascular health in nonobese subjects with healthy metabolism. However, little is known regarding the prognosis across the range of metabolic phenotypes once cardiovascular disease is established. We examined the prognosis of patients with acute myocardial infarction (AMI) stratified according to metabolic health and obesity status.MethodsThis is a retrospective study on consecutive patients with AMI admitted to a tertiary hospital between 2014 and 2021. Patients were allocated into the following 4 groups based on metabolic and obesity profile: (1) metabolically healthy obese (MHO), (2) metabolically healthy nonobese (MHNO), (3) metabolically unhealthy obese (MUO), and (4) metabolically unhealthy nonobese (MUNO). Metabolic health was defined in accordance to the Biobank Standardisation and Harmonisation for Research Excellence in the European Union Healthy Obese Project. The primary outcome was all-cause mortality. The Cox regression analysis examined the independent association between mortality and metabolic phenotypes, adjusting for age, sex, AMI type, chronic kidney disease, smoking status, and left ventricular ejection fraction.ResultsOf 9958 patients, the majority (68.5%) were MUNO, followed by MUO (25.1%), MHNO (5.6%), and MHO (0.8%). MHO had the lowest mortality (7.4%), followed by MHNO (9.7%), MUO (19.2%), and MUNO (22.6%) (P < .001). Compared with MHNO, MUO (hazard ratio [HR], 1.737; 95% confidence interval [CI], 1.282-2.355; P < .001) and MUNO (HR, 1.482; 95% CI, 1.108-1.981; P = .008) had a significantly higher mortality risk but not MHO (HR, 1.390; 95% CI, 0.594-3.251; P = .447), after adjusting for confounders. The Kaplan-Meier curves showed favorable survival in the metabolically healthy and obesity groups, with the highest overall survival in the MHO, followed by MHNO, MUO, and MUNO (P < .001).ConclusionMetabolically healthy and obese patients with AMI have favorable prognosis compared with metabolically unhealthy and nonobese patients. It is equally important to prioritize intensive metabolic risk factor management to weight reduction in the early phase after AMI.     

Arterial Stiffness,Carotid Intima-Media Thickness,Endocan, and A Disintegrin and Metalloproteinase With Thrombospondin Type I Motif 9 Levels and Their Relationship With Disease Activity in Patients With Acromegaly With and Without Cardiovascular Risk Factors

ObjectiveCardiovascular complications such as cardiomyopathy and endothelial dysfunction, which are frequently seen in patients with acromegaly, are among the most important causes of morbidity and mortality. In this study, we aimed to investigate arterial stiffness, carotid intima-media thickness, endocan level, and A disintegrin and metalloproteinase with thrombospondin type I motif 9 level and their relationship with disease activity in patients with acromegaly with and without cardiovascular risk factors.MethodsA total of 60 patients with acromegaly—25 with active disease, 26 with well-controlled disease, and 9 with newly diagnosed disease—and 60 age-, sex-, and body mass index (BMI)-matched healthy control subjects were enrolled in this study. All the subjects’ height, weight, BMI, systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting plasma glucose (FPG) level, insulin, hemoglobin A1C (HbA1C), C-reactive protein , lipid, endocan, A disintegrin and metalloproteinase with thrombospondin type I motif 9 levels, pulse wave velocity (PWV), and carotid intima-media thickness were measured.ResultsThe SBP, DBP, FPG level, HbA1C level, and PWV of the acromegaly group were higher than those of the control group. In patients with acromegaly with cardiovascular disease (CVD) risk factors, the PWV was higher than that in the control group, and in patients with acromegaly without CVD risk factors, the PWV was similar to that in the control group. In a correlation analysis, a positive correlation was found between PWV and age, BMI, SBP, DBP, FPG level, and HbA1C level in the acromegaly group.ConclusionIn our study, we found that arterial stiffness increased in patients with acromegaly with CVD risk factors and that increased arterial stiffness was associated with hemodynamic (SBP and DBP) and metabolic (BMI, FPG level, and HbA1C level) parameters.     

Comparison of New Glucose-Lowering Drugs on the Risk of Pancreatitis in Type 2 Diabetes: A Network Meta-Analysis

ObjectiveTo explore whether new glucose-lowering drugs increase the risk of pancreatitis in individuals with type 2 diabetes. This present network meta-analysis aimed to investigate the risk of pancreatitis associated with the use of glucagon-like peptide-1 (GLP-1) agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors in the treatment of type 2 diabetes mellitus.MethodsPubMed, Web of Science, Embase, and the Cochrane Library were searched. The literature was published from the date of their inception to July 21, 2021, including placebo-controlled or head-to-head trials of 2 new glucose-lowering drugs. The relative ratio (RR) and 95% confidence interval (CI) were used to assess the risk of GLP-1 agonists and DPP-4 inhibitors for pancreatitis or pancreatic cancer among patients with type 2 diabetes.ResultsSeventeen studies were identified, covered 102 257 participants. The pooled results showed a neutral relationship between GLP-1 agonists and pancreatitis (overall RR, 0.96; 95% CI, 0.31-3.00) or pancreatic cancer (overall RR, 1.10; 95% CI, 0.31-4.10) compared with placebo. Meanwhile, DPP-4 inhibitors were not associated with the increased risk of pancreatitis (overall RR, 1.60; 95% CI, 0.25-11.00) or pancreatic cancer (overall RR, 0.79; 95% CI, 0.26-2.40). Among them, lixisenatide and saxagliptin may be the safest drugs compared with other drugs according to the ranking of probability. Sensitivity and subgroup analysis confirmed the stability of the core results.ConclusionThe most obvious finding of this study is that GLP-1 agonists and DPP-4 inhibitors are safe with respect to the risk of pancreatitis and pancreatic cancer compared with placebo. This conclusion may provide useful evidence for correlated clinical researches.     

Personalized Medical Treatment of Patients With Acromegaly: A Review

Acromegaly is associated with significant morbidity and mortality if it is not appropriately treated. In addition to insulin-like growth factor 1 and growth hormone normalization as well as tumor shrinkage, the treatment goals include relieving symptoms, managing complications, and improving patients’ quality of life. Surgical resection is a first-line treatment option for most patients, with few being pretreated preoperatively with medications. Somatostatin receptor ligands (SRLs), injectable and, more recently, oral capsules, have been the cornerstone of first-line medical therapy for persistent disease. However, several factors, including sparsely granulated adenomas, absent or low somatostatin receptor status, T2-hyperintensity imaging, young age, and aryl hydrocarbon receptor-interacting protein mutations, can predict first-generation SRL resistance. Patients with these characteristics may be better candidates for the growth hormone receptor antagonist pegvisomant, or in cases of large tumors, the second-generation SRL pasireotide. Combination therapy should be further pursued in patients who remain biochemically uncontrolled or have a high remnant tumor after monotherapy. An efficacious and cost-effective pegvisomant dose-sparing effect of SRLs when used in combination has been demonstrated. With such a wide array of medical treatment options, it is becoming increasingly important to tailor treatment to patients’ unique characteristics and preferences, with a goal of personalizing management to achieve high-quality outcomes.     

Does a MediDiet With Additional Extra Virgin Olive Oil and Pistachios Reduce the Incidence of Gestational Diabetes?

ObjectiveThe present study aimed to evaluate gestational diabetes mellitus (GDM) incidence in pregnant women following the Mediterranean diet (MedDiet) with the addition of extra virgin olive oil (EVOO) and pistachios.MethodsA total of 560 pregnant patients were enrolled in the present study. The MedDiet was introduced in both the interventional group (IG) and the control group. The women in the IG received 40 mL of EVOO every day along with 25 to 30 g of roasted pistachios. The incidence of GDM was recorded along with specific maternal and neonatal outcomes.ResultsThe nutritional scores and MedDiet adherence screener scores were not statistically different between the groups at baseline, but the difference was statistically significant and higher in the IG at 24 to 28 weeks (P = .001) and at 36 to 38 weeks (P = .001). GDM was diagnosed in 51 (20.4%) women in the control group and 34 (13.6%) women in the IG. The MedDiet significantly reduced GDM incidence (P = .02) after adjusting for confounding factors.ConclusionThe present study shows that dietary intervention in pregnant women, including a MedDiet and increased consumption of EVOO and pistachios, decreases the incidence of GDM.
