Article Synopsis
  • Widespread insect losses pose a significant global concern, necessitating an understanding of the drivers behind these declines and the coverage of insects within protected areas.
  • The study utilized extensive insect DNA metabarcoding data from 31,846 flying insect species across Germany to analyze the effects of differing land cover, weather, and protection status on insect biodiversity.
  • Findings revealed that increased land cover heterogeneity leads to higher insect biomass and species richness, particularly in low-vegetation habitats, which, despite their biodiversity, are often under-protected in conservation efforts.

Objective: To evaluate whether continuous glucose monitoring (CGM) could assist providers in intensifying glycemic management in hospitalized patients with type 2 diabetes.

Research Design And Methods: At six academic hospitals, adults with type 2 diabetes hospitalized in a non-intensive care setting were randomly assigned to either standard therapy with glucose target 140-180 mg/dL (standard group) or intensive therapy with glucose target 90-130 mg/dL guided by CGM (intensive group). The primary outcome was mean glucose measured with CGM (blinded in standard group), and the key secondary outcome was CGM glucose <54 mg/dL.

Introduction: We investigated the genetic determinants of variation in the hemoglobin glycation index (HGI), an emerging biomarker for the risk of diabetes complications.

Methods: We conducted a genome-wide association study (GWAS) for HGI in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial ( = 7,913) using linear regression and additive genotype encoding on variants with minor allele frequency greater than 3%. We conducted replication analyses of top findings in the Atherosclerosis Risk in Communities (ARIC) study with inverse variance-weighted meta-analysis.

Article Synopsis
  • The study investigates how metformin use in adults with type 2 diabetes may impact the incidence of postacute sequelae of SARS-CoV-2 (PASC) and death after COVID-19 infection.
  • Findings indicate that metformin users had a lower risk of death and PASC compared to those on other diabetes medications, with hazard ratios suggesting reduced incidence in the National COVID Cohort Collaborative (N3C).
  • The results support previous observations that metformin may lead to better outcomes post-COVID-19, although the incidence of PASC was notably higher when assessed with computable phenotypes compared to EHR codes.

We recently developed a machine-learning subgrouping algorithm, iterative causal forest (iCF), to identify subgroups with heterogeneous treatment effects (HTEs) using predefined covariates. However, such predefined covariates may miss or poorly define important features leading to inaccurate subgrouping. To address such limitations, we developed a new semi-automatic subgrouping algorithm, hdiCF, which adapts methodology from high-dimensional propensity score for feature recognition in claims data.

One obstacle to adopting instrumental variable (IV) methods in pharmacoepidemiology is their reliance on strong, unverifiable assumptions. We can falsify IV assumptions by leveraging the causal structure, which can strengthen or refute their plausibility and increase the validity of effect estimates. We illustrate a systematic approach to evaluate calendar time IV assumptions in estimating the known effect of thiazolidinediones on hospitalized heart failure.

Contrary to current insulin formulations, endogenous insulin has direct access to the portal vein, regulating glucose metabolism in the liver with minimal hypoglycaemia. Here we report the synthesis of an amphiphilic diblock copolymer comprising a glucose-responsive positively charged segment and polycarboxybetaine. The mixing of this polymer with insulin facilitates the formation of worm-like micelles, achieving highly efficient absorption by the gastrointestinal tract and the creation of a glucose-responsive reservoir in the liver.

Objective: The coronavirus 2019 (COVID-19) pandemic has evolved over time by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant, disease severity, treatment, and prevention. There is evidence of an elevated risk of incident diabetes after COVID-19; our objective was to evaluate whether this association is consistent across time and with contemporary viral variants.

Research Design And Methods: We conducted a retrospective cohort study using National COVID Cohort Collaborative (N3C) data to evaluate incident diabetes risk among COVID-positive adults compared with COVID-negative patients or control patients with acute respiratory illness (ARI).

Aim: The decline in estimated glomerular filtration rate (eGFR), a significant predictor of cardiovascular disease (CVD), occurs heterogeneously in people with diabetes because of various risk factors. We investigated the role of eGFR decline in predicting CVD events in people with type 2 diabetes in both primary and secondary CVD prevention settings.

Materials And Methods: Bayesian joint modelling of repeated measures of eGFR and time to CVD event was applied to the Exenatide Study of Cardiovascular Event Lowering (EXSCEL) trial to examine the association between the eGFR slope and the incidence of major adverse CV event/hospitalization for heart failure (MACE/hHF) (non-fatal myocardial infarction, non-fatal stroke, CV death, or hospitalization for heart failure).

Objective: To compare postprandial glucose excursions following a bolus with inhaled technosphere insulin (TI) or subcutaneous rapid-acting analog (RAA) insulin.

Research Design And Methods: A meal challenge was completed by 122 adults with type 1 diabetes who were using multiple daily injections (MDI), a nonautomated pump, or automated insulin delivery (AID) and who were randomized to bolus with their usual RAA insulin (n = 61) or TI (n = 61).

Results: The primary outcome, the treatment group difference in area under the curve for glucose >180 mg/dL over 2 h, was less with TI versus RAA (adjusted difference -12 mg/dL, 95% CI -22 to -2, P = 0.

Introduction: Even with recent treatment advances, type 2 diabetes (T2D) remains poorly controlled for many patients, despite the best efforts to adhere to therapies and lifestyle modifications. Although estimates vary, studies indicate that in >10% of individuals with difficult-to-control T2D, hypercortisolism may be an underlying contributing cause. To better understand the prevalence of hypercortisolism and the impact of its treatment on T2D and associated comorbidities, we describe the two-part Hyper ortisolism in P ients with Difficult to Control Type 2 Di betes Despite Receiving Standard-of-Care Therapies: Preva ence and Treatment with Korl m (Mifepri one) (CATALYST) trial.

Although recent evidence suggested that glucagon-like peptide 1 receptor agonists (GLP1RAs) might reduce the risk of asthma exacerbations, it remains unclear which subpopulations might derive the most benefit from GLP1RA treatment. To identify characteristics of patients with asthma that predict who might benefit the most from GLP1RA treatment using real-world data. We implemented an active-comparator, new-user design analysis using commercially ensured patients 18-65 years of age from MarketScan data for 2007-2019 and identified two cohorts: GLP1RAs versus thiazolidinediones and GLP1RAs versus sulfonylureas.

  • Diabetes complications, like retinopathy and neuropathy, occur more frequently in individuals of African ancestry, partly due to G6PD deficiency which is associated with malaria resistance and lowers HbA1c levels by affecting red blood cell lifespan.
  • A study discovered a specific variant (rs1050828-T) linked to G6PD deficiency that increases the risk of diabetes complications, showing that glucose levels influence retinopathy risk significantly.
  • The findings suggest that adjusting diabetes management based on glucose levels or genetic factors could improve diagnosis and treatment, potentially reducing complications for those with G6PD deficiency.

Objective: A new generation of basal insulin analogs enabling once-weekly administration is currently under development. Weekly basal insulins have the potential to overcome limitations exhibited by current daily basal insulins. The pharmacokinetic and glucodynamic characteristics differ significantly between weekly and daily basal insulins and will require paradigm shifts in how basal insulins are dosed.
