Summary: This study analyzed the whole-pancreas gene expression of recently diagnosed type 1 diabetes (T1D) patients and found that the expression of core acinar cell genes was higher in the patients compared to non-diabetic controls. Upregulation of immune and inflammation related genes was observed in the pancreatic islets of T1D patients, while downregulation of regenerating gene family (REG) genes was observed in the exocrine acinar cell dominated whole-pancreas samples. The study highlights the importance of studying both exocrine and endocrine compartments of the pancreas to better understand the molecular mechanisms of T1D.

Summary: In the past few decades, various approaches have been explored to restore sufficient β-cell mass in diabetic patients. Stem cells are an attractive source of new β-cells, while inducing endogenous regeneration is also an alternative option. This review summarizes the latest evidence on physiological and pathological conditions associated with pancreatic regeneration and proliferation, as well as the signaling cascade mediating cell growth.

Summary: The study aimed to assess the differences in subjective cognitive dysfunction between major depressive disorder (MDD) and recently diagnosed Bipolar Disorder (BD) across euthymia and mood episodes. Results showed higher subjective cognitive dysfunction in individuals recently diagnosed with BD compared to those with MDD during euthymia.

Summary: The study revealed differences in sleep efficiency and disturbances between euthymic BD and MDD, highlighting the importance of regular sleep assessments for individuals recently diagnosed with BD. These differences can provide valuable insights for prognosis, treatment, and the presence of subsyndromal symptoms in the absence of a mood episode.

Summary: The study aimed to investigate pancreatic exocrine function in patients with type 1 diabetes (T1D) using non-invasive tests. Results showed that impaired exocrine pancreatic function, marked by low fecal elastase-1, serum pancreatic amylase, and lipase levels, is associated with reduced nutritional indexes in T1D patients.

Summary: This study assessed racial/ethnic differences in the receipt of guideline-directed diabetes care for complication prevention by individuals recently diagnosed with diabetes. Hispanics recently diagnosed with diabetes were found to be less likely to receive some indicators of guideline-directed care for the prevention of complications, with lack of insurance and SES potentially explaining these differences. Future work should consider policy change and providers' behaviors linked to racial/ethnic disparities in diabetes care.

Summary: A study evaluated the diabetes-specific functioning among parents of young children newly diagnosed with Type 1 diabetes. The findings suggest that parents' emotional functioning and family protective factors are associated with their diabetes-specific functioning, and child-illness factors are related to both parents' diabetes-specific and emotional functioning.

Summary: Pancreatitis and diabetes are prevalent among Aboriginal and non-Aboriginal people in Central Australia. Alcohol is the most common cause of pancreatitis among Aboriginal people, while biliary causes are more common among non-Aboriginal people. Post-pancreatitis diabetes mellitus (PPDM) diagnosis testing is insufficient.

Summary: Exocrine pancreas dysfunction precedes the onset of type 1 diabetes in adult at-risk individuals and may be unrelated to fasting C-peptide levels. High-risk HLA genotypes negatively affected P-amylase levels in autoantibody negative adult individuals.

Summary: The aim of this study was to investigate whether an increased bolus: basal insulin ratio with liver-targeted bolus insulin would increase bolus insulin usage and decrease hypoglycaemic events. The results showed that liver-targeted bolus insulin safely decreased hypoglycaemic events and symptoms without compromising glucose control.

Summary: The aim of this study was to analyze the initial and subsequent treatments prescribed to newly diagnosed type 2 diabetes mellitus patients. The majority of patients started treatment with a single metformin medication, while a smaller percentage began with combination therapy. Metformin was the most commonly used first and third-line therapy, while metformin with DPP4i or sulfonylurea combination therapy was more prevalent as second-line therapy.

Summary: In type 1 diabetes patients, CD8(+) T cells infiltrate the pancreas with high frequency, reactive against specific epitope derived from preproinsulin signal peptide. The study also showed the heterogeneity of islet distribution and CD8(+) T-cell infiltration, contributing to limited existing knowledge of T-cell reactivity in the pancreas of donors with recent-onset T1D. Antigen-specific therapies directed toward preproinsulin could have high clinical impact.

Summary: Autoimmune thyroid disorders such as Hashimoto's thyroiditis and Graves' disease are thought to potentially have origins in enterovirus infections of thyroid cells. Research has shown that persistent enterovirus infection in thyroid tissue from AITD patients can suppress interferon and cytokine pathways while upregulating genes associated with immune responses. These findings suggest a potential benefit in targeting viral infections and inflammation in the early stages of AITD.

Summary: The interaction between genetic and environmental factors determines the development of type 1 diabetes. Some viruses can infect and damage pancreatic beta cells, and MDA5 may play a role in the response of pancreatic islets to viral infections. In T1D donors, MDA5 expression is increased and may characterize dedifferentiated or newly forming islet cells.

Summary: The study reveals that newly diagnosed type 1 diabetes patients have enhanced gene expressions related to cellular stress and increased immunological activity in their islet cells compared to controls. Additionally, increased viral response proteins were observed in beta-cells of newly diagnosed type 1 diabetes patients, providing evidence for the hypothesis that enteroviral infection of islet beta-cells contributes to the pathogenesis of type 1 diabetes.

Summary: This study suggests that dormant beta cells in type 1 diabetes (T1D) exhibit secretion defects, fetal dedifferentiation, and desynchronization. Combining with previous evidence, it is proposed to treat individuals with ongoing T1D development prophylactically with type 2 diabetes (T2D) medicine and anti-inflammatory compounds to reactivate dormant beta cells and prevent autoimmune destruction. Further investigation into T2D mechanisms during T1D development is needed.

Summary: This study aimed to identify transcriptional changes associated with disease progression in patients with recent-onset type 1 diabetes. They found that genes and pathways related to innate immunity were downregulated during the first year after diagnosis. Associations between gene expression changes and ZnT8A autoantibody positivity were also observed. Additionally, changes in the expression of 16 genes were found to predict the decline in C-peptide at 24 months, and increased B cell levels and decreased neutrophil levels were associated with rapid progression, consistent with previous reports.

Summary: This study showed that acinar nuclei density is preserved and no acinar atrophy is found in type 1 diabetes. The expression of digestive enzymes is evenly distributed, with occasional amylase-negative regions in formalin-fixed tissues. Transcriptional alterations in type 1 diabetes in the acinar tissue, independent of the distance from islets, were also identified. The enrichment of gene sets Myc Targets V2 and Estrogen Response Early may be linked to the increased incidence of pancreatic cancer in type 1 diabetes.

Summary: This study found that among females with type 1 diabetes, illness perception personal control and coping strategy seeking emotional social support explained 23.2% of the variance in hemoglobin A1c, while among males, personal control remained significant and explained 13.9% of the variance. The associations between psychological aspects and hemoglobin A1c suggest that addressing these aspects clinically may help improve metabolic control and reduce the risk of complications.
