Article Synopsis
  • Eosinophilic gastrointestinal disorders (EGIDs) are rising significantly in incidence and prevalence, with a major focus on eosinophilic esophagitis (EoE), particularly in Israel from 2014 to 2021.
  • The study, based on electronic medical records of a population of 2.4 million, shows that the incidence rate of EGIDs tripled during the study period, while prevalence soared from 14.53 to 51.43 per 100,000 persons.
  • The trends for increased cases are consistent across different age groups and sexes, indicating that the rise in EGIDs, especially EoE, shows no signs of plateauing by the end of 2021.

Background: The incidence of early-onset colorectal cancer (EOCRC) rose abruptly in the mid 1990s, is continuing to increase, and has now been noted in many countries. By 2030, 25% of American patients diagnosed with rectal cancer will be 49 years or younger. The large majority of EOCRC cases are not found in patients with germline cancer susceptibility mutations (eg, Lynch syndrome) or inflammatory bowel disease.

Background: Contemporary guidelines recommend the use of sodium-glucose cotransporter 2 inhibitors (SGLT2is) independently of glycemic control in patients with type 2 diabetes and those with kidney disease, with heart failure, or at high risk of cardiovascular disease. Using a large Israeli database, we assessed whether long-term use of SGLT2is versus dipeptidyl peptidase 4 inhibitors (DPP4is) is associated with kidney benefits in patients with type 2 diabetes overall and in those without evidence of cardiovascular or kidney disease.

Methods: Patients with type 2 diabetes who initiated SGLT2is or DPP4is between 2015 and 2021 were propensity score-matched (1:1) according to 90 parameters.

Background: In clinical trials enrolling patients with type 2 diabetes (T2D) at high cardiovascular risk, many glucagon-like peptide-1 receptor agonists (GLP-1 RAs) improved albuminuria status and possibly mitigated kidney function loss. However, limited data are available regarding the effects of GLP-1 RAs on albuminuria status and kidney function in real-world settings, including populations with a lower baseline cardiovascular and kidney risk. We assessed the association of GLP-1 RAs initiation with long-term kidney outcomes in the Maccabi Healthcare Services database, Israel.

Mortality prevention in T2D elderly population having Chronic Kidney Disease (CKD) may be possible thorough risk assessment and predictive modeling. In this study we investigate the ability to predict mortality using heterogeneous Electronic Health Records data. Temporal abstraction is employed to transform the heterogeneous multivariate temporal data into a uniform representation of symbolic time intervals, from which then frequent Time Intervals Related Patterns (TIRPs) are discovered.

Mortality in the type II diabetic elderly population can sometimes be prevented through intervention, for which risk assessment through predictive modeling is required. Since Electronic Health Records data are typically heterogeneous and sparse, the use of Temporal Abstraction and time intervals mining to discover frequent Time Intervals Related Patterns (TIRPs) is employed. While TIRPs are used as features for a predictive model, the temporal relations between them in general, and among each TIRP's instances are not represented.

Background: Randomized controlled trials showed that sodium/glucose cotransporter-2 inhibitors (SGLT2i) protect the heart and kidney in an array of populations with type 2 diabetes (T2D) and increased cardiorenal risk. However, the extent of these benefits also in lower kidney-risk T2D populations needs further investigation.

Methods: Members of Maccabi Healthcare Systems listed in their T2D registry who initiated new glucose lowering agents (GLA), were divided into SGLT2i initiators and other GLAs (oGLAs).

Aims: Randomized controlled trials have shown that insulin glargine 300 U/mL (Gla-300) has a more stable and prolonged glucose lowering effect among patients with type 2 diabetes (T2DM) compared to insulin glargine 100 U/mL (Gla-100), resulting in a reduced risk of hypoglycaemia while maintaining a similar efficacy of lowering HbA. We aimed to investigate if the effectiveness of Gla-300 is reproducible in real-world settings.

Material And Methods: In this retrospective cohort study, data from a large state-mandated health organization were used to identify adult T2DM patients who were previously on insulin and initiated Gla-300 therapy between 6/ 2016 and 12/2017.

Introduction: Insulin degludec/liraglutide (IDegLira) is a fixed-ratio combination (FRC) of basal insulin and glucagon-like protein-1 receptor agonist (GLP-1 RA) that has demonstrated glycemic and metabolic benefits in patients with type 2 diabetes mellitus (T2DM) in both randomized controlled trials and real-world studies. The impact of adherence to this medication and its effect on patients with T2DM who switch from loose-dose combination therapy to a FRC of insulin and GLP-1RA have not yet been reported. We have examined the metabolic effects and adherence to this medication in a real-life setting, in T2DM patients who initiated IDegLira therapy after being treated with other glucose-lowering drugs.
