4. Comprehensive Medical Evaluation and Assessment of Comorbidities: Standards of Care in Diabetes-2024

Respiratory syncytial virus vaccination in older adults and patients with chronic disorders: A position paper from the Portuguese Society of Pulmonology, the Portuguese Association of General and Family Medicine, the Portuguese Society of Cardiology, the Portuguese Society of Infectious Diseases and Clinical Microbiology, the Portuguese Society of Endocrinology, Diabetes and Metabolism, and the Portuguese Society of Internal Medicine

BACKGROUND

Respiratory syncytial virus (RSV) is an important cause of lower respiratory tract infection, hospitalisation and death in adults.

METHODS

Based on evidence regarding the impact of RSV on adult populations at risk for severe infection and the efficacy and safety of RSV vaccines, the Portuguese Society of Pulmonology, the Portuguese Association of General and Family Medicine, the Portuguese Society of Cardiology, the Portuguese Society of Infectious Diseases and Clinical Microbiology, the Portuguese Society of Endocrinology, Diabetes and Metabolism, and the Portuguese Society of Internal Medicine endorses this position paper with recommendations to prevent RSV-associated disease and its complications in adults through vaccination.

CONCLUSION

The RSV vaccine is recommended for people aged ≥50 years with risk factors (chronic obstructive pulmonary disease, asthma, heart failure, coronary artery disease, diabetes, chronic kidney disease, chronic liver disease, immunocompromise, frailty, dementia, and residence in a nursing home) and all persons aged ≥60 years. If it cannot be made available to this population, then the vaccine should be prioritised for individuals aged ≥75 years and those aged ≥50 years with risk factors. The vaccine should preferably be given between September and November and can be co-administered with the influenza vaccine. Ongoing studies on RSV vaccines may justify extending these recommendations in the future.

Development and Validation of the Scale of Hypoglycemia Self-Care Behavior in Type 2 Diabetes

BACKGROUND

Inappropriate dietary, exercise, and medication self-care behaviors among persons with diabetes can easily trigger hypoglycemia. Clinically, it is necessary to quickly identify high-risk groups for hypoglycemic events to provide targeted hypoglycemia education. However, there is currently a lack of precise tools to assess self-care behaviors related to hypoglycemia.

OBJECTIVES

The aim of the study was to develop and validate a hypoglycemia self-care behavior scale for evaluating the behaviors of persons with diabetes in handling and preventing hypoglycemic events.

METHODS

A cross-sectional study with purposive sampling was conducted to recruit 300 persons with Type 2 diabetes who had experienced hypoglycemic events from a medical center and a primary care clinic in southern Taiwan. Data were collected using a structured questionnaire from December 2021 to September 2023.

RESULTS

The original Hypoglycemia Self-Care Behavior Scale, comprising 26 items, was reduced to 17 items, measuring six factors after exploratory factor analysis. Subsequently, the scale was further refined to 10 items covering four factors through structural equation modeling. Validity and reliability were assessed during this process, and the developed scale was subsequently verified for both. Factor loadings ranged from .50-.97, explaining 76% of the total variance. The four factors included "hypoglycemia recognition and carbohydrate supplementation," "prevention of hypoglycemia during exercise," "carbohydrate assessment," and "seeking medical assistance." The Hypoglycemia Self-Care Behavior Scale-developed and validated through structural equation modeling-demonstrates satisfactory model fit, convergent validity, and discriminant validity. Internal consistency was within the range of .73-.94, indicating strong reliability.

DISCUSSION

The Hypoglycemia Self-Care Behavior Scale not only functions as a tool for the rapid assessment of self-care behaviors during hypoglycemic events by clinical healthcare professionals but can also serve as reference for hypoglycemia-related health education.

Vaccination of people with solid tumors and diabetes: existing evidence and recommendations. A position statement from a multidisciplinary panel of scientific societies

Diabetes and cancer are two of the most common public health concerns worldwide. The complex interplay of these two conditions is a growing area of research, as patients with diabetes are at increased risk for developing cancer, and vice versa. Furthermore, both patient populations show increased risk of many communicable infectious diseases and their adverse consequences, while vaccination can play a crucial role in their prevention, improving patient outcomes. Vaccination should represent a standard part of care for patients with cancer, diabetes, and both the diseases simultaneously, including people undergoing cancer treatment or in remission. Several international guidelines provide recommendations for vaccinating people with cancer or diabetes, but the two conditions have not been specifically evaluated together. Here we present a multidisciplinary consensus position paper on vaccination in patients with cancer and diabetes. The position paper is the result of a collaborative effort between experts from the Italian Association of Medical Oncology (AIOM), Italian Association of Medical Diabetologists (AMD), Italian Society of Diabetology (SID), Italian Society of Endocrinology (SIE), and Italian Society of Pharmacology (SIF). The paper provides a comprehensive overview of the current state-of-the-art knowledge on vaccination in patients with cancer and diabetes. It discusses the importance of vaccination in preventing infections, focuses attention on the need to consider the unique challenges faced by patients with cancer and diabetes when it comes to vaccine administration, and highlights the need for coordinated care to optimize treatment outcomes. Overall, the consensus position paper provides healthcare professionals caring for patients with cancer and diabetes recommendations on the use of various vaccines, including influenza, COVID-19, HZV, and HPV vaccines, as well as guidance on how to address common concerns and challenges related to vaccine administration.

Adolescent Girls With Type 1 Diabetes Develop Changes in Bone Prior to Evidence of Clinical Neuropathy

CONTEXT

Neuropathy and fracture are prevalent complications of type 1 diabetes (T1D). Although correlated in the clinical literature, it remains unknown whether neuropathy contributes to the initiation of bone loss at the earliest stages of disease.

METHODS

We performed a single-center, cross-sectional study to quantify parameters of nerve and bone health in adolescent girls with T1D (n = 21) and associated controls (n = 12). Groups were well matched for age, height, strength, and physical activity.

RESULTS

By high-resolution peripheral quantitative computed tomograpy, participants with T1D had lower trabecular bone volume fraction at the distal radius (-14.6%, P-adj = .095) and the tibia (-12.8%, P-adj = .017) and decreased trabecular thickness (-8.3% radius, P-adj = .007; -7.5% tibia, P-adj = .034) after adjustment for body size. In the tibia only, cortical bone mineral density was increased by 8.6% (P-adj = .024) and porosity was decreased by 52.9% with T1D (P-adj = .012). There were no significant differences in bone density by dual-energy x-ray absorptiometry. Participants with T1D also had lower circulating levels of osteocalcin (-30%, P = .057), and type I collagen cross-linked C-telopeptide (-36%, P = .035), suggesting low bone formation and turnover in T1D. Based on the Michigan Neuropathy Screening Instrument, 9.5% of those with T1D had clinical evidence of diabetic peripheral neuropathy. However, consideration of neuropathy status failed to explain the widespread T1D-associated changes in bone.

CONCLUSION

Our study defines early deficits in trabecular bone microarchitecture, decreased cortical porosity in the tibia, and suppression of biomarkers of bone turnover in adolescent girls with T1D, prior to the onset of symptomatic peripheral neuropathy. These findings inform our understanding of the rapid progression of skeletal disease in young girls with T1D and suggests that early detection and management strategies may help to prevent fracture and related comorbidities later in life.

Biases in the performance of FRAX without BMD in predicting fracture risk in a multiethnic population with diabetes: the Diabetes and Aging Study

Fracture risk calculators, such as the Fracture Risk Assessment Tool (FRAX), calculate the risk of major osteoporotic fracture (MOF) and hip fracture but do not account for the excess risk of fracture in people with diabetes. We examined the predictive performance of FRAX without BMD in ethnically diverse, older patients with diabetes. Patients included were between ages 65 and 89 from the Kaiser Permanente Northern California Diabetes Registry and not already taking osteoporosis medications. Race and ethnicity were self-identified. We calculated FRAX without BMD based on baseline characteristics and assessed how well FRAX predicted MOF and hip fracture over follow-up. Predictive performance was based on measures of discrimination (area under the receiver operator curve, AUC) and calibration (observed-to-predicted ratio, O/P). We identified 96 914 patients (47.0% female), of whom 5383 (5.6%) and 1767 (1.8%) had MOF and hip fracture, respectively, over a mean follow-up of 4.3 yr. The AUC for MOF and hip fracture were 0.72 and 0.77, respectively. FRAX mildly underestimated MOF and hip fracture rates (O/P 1.2 for both) overall. Discrimination was similar by race and ethnicity and diabetes duration but was worse in those over age 75 (AUC < 0.7). In some groups, there were substantial calibration errors, such as Hispanic women (O/P: 1.8 and 1.5), Black men (O/P: 1.5 and 1.8), those with duration of diabetes ≥20 yr (O/P: 1.6 and 1.5), and those over the age of 80 (O/P: 1.4 and 1.2) for MOF and hip fracture, respectively. While the discriminatory performance of FRAX without BMD was good overall in patients with diabetes, it underestimated risk in Hispanic women, Black men, those with long duration of diabetes, and in the oldest patients with diabetes. These algorithmic biases suggest that diabetes-specific tools may be needed to stratify fracture risk in patients with diabetes.

Risk of Serious Bacterial and Non-Bacterial Infections in People With MASLD

Metabolic dysfunction-associated steatotic liver disease (MASLD) has become the most common chronic liver disease globally. MASLD is a multisystem disease where metabolic dysfunction plays a key role in the development of MASLD and its most relevant liver-related morbidities and extrahepatic complications, such as cardiovascular disease, chronic kidney disease and certain types of extrahepatic cancers. Among the least examined MASLD-related extrahepatic complications, an ever-increasing number of observational studies have reported a positive association between MASLD and the risk of serious bacterial infections (SBI) requiring hospital admission. This risk remained significant in those studies where statistical analysis was adjusted for age, sex, ethnicity, obesity, type 2 diabetes and other common comorbidities. Notably, the incidence rates of SBI were further increased with more advanced MASLD, especially in patients with MASLD-related cirrhosis, and were also observed for some acute viral infections, including SARS-CoV-2 infection, leading to severe COVID-19. In this narrative review article, we provide an overview of the literature on (a) the recent epidemiological data linking MASLD to the risk of serious bacterial and non-bacterial infections requiring hospital admission, (b) the putative underlying mechanisms through which MASLD may increase the susceptibility to serious infections, both directly and through the immune dysfunction associated with cirrhosis and portal hypertension, and (c) the practical and clinical implications of the increased risk of serious bacterial and non-bacterial infections in the growing global population with MASLD.

Benefits and disadvantages of combination therapy with imeglimin and metformin in patients with type 2 diabetes

BACKGROUND

We retrospectively examined the benefits and disadvantages of adding imeglimin to metformin therapy in patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS

Ninety-four patients with type 2 diabetes who had been administered imeglimin were included in the safety analysis set (SAS). Sixty-four patients who had been treated with imeglimin for over 6 months were included in the full analysis set (FAS). The primary outcome was the change in HbA1c levels in the FAS. The secondary outcomes were gastrointestinal adverse events (AEs) in the SAS and changes in body weight and FIB-4 in theFAS.

RESULTS

In the SAS, gastrointestinal AEs occurred in 15 of 40 (38%) metformin users and 6 of 54 (11%) non-users. In the FAS, HbA1c levels were significantly reduced in both metformin users (n = 27, baseline, 8.5 ± 1.1%;6 months, 7.7 ± 1.2%) and non-users (n = 37, baseline, 8.0 ± 0.9%; 6 months,7.4 ± 0.9%). While body weight (from 72.0 ± 20.5 kg to 70.9 ± 20.8 kg) and FIB-4 (from 1.27 ± 0.57 to 1.17 ± 0.49) significantly decreased in metformin users, they did not significantly differ in non-users.

CONCLUSIONS

Adding imeglimin to metformin therapy demonstrated favorable reductions in HbA1c, body weight, and FIB-4 in patients with type 2 diabetes, although it was associated with the incidence of gastrointestinal AEs.

Hypoglycemia knowledge assessment tool - Development and validation of the Hypoglycemia Management Knowledge Scale in Taiwan

BACKGROUND

Knowledge can guide and support behaviors. With accurate knowledge, patients are better equipped to engage in appropriate self-care behaviors and effectively manage hypoglycemia. However, there is currently a lack of reliable and valid assessment scales specifically designed to measure hypoglycemia knowledge, which could serve as valuable clinical evaluation tools for healthcare professionals.

AIM

To develop and validate a reliable and valid hypoglycemia management knowledge scale to assess the knowledge of hypoglycemia management in patients with diabetes.

METHODS

A cross-sectional study was conducted, recruiting 300 patients with type 2 diabetes who had experienced hypoglycemic events from a medical center and a primary care clinic in southern Taiwan between December 2021 and September 2023.

RESULTS

Initially, 25 questions were selected, achieving a content validity index of 0.92. Through exploratory factor analysis and confirmatory factor analysis, the scale was refined into an 8-factor and 3-factor model, with factor loadings ranging from 0.5 to 0.9. The questions were categorized into three factors: blood glucose determination, carbohydrate supplementation, and blood glucose testing. The internal consistency, measured using the Kuder-Richardson 20 (KR-20), was 0.758.

CONCLUSIONS

The hypoglycemia management knowledge scale developed in this study demonstrated sufficient validity and reliability, making it a useful tool for quickly assessing patients' knowledge of hypoglycemia management and serving as a reference for hypoglycemia education.

Modifiable risk factors and plasma proteomics in relation to complications of type 2 diabetes

A comprehensive assessment of combined modifiable risk factors with common complications of type 2 diabetes (T2D) is lacking, and the potential role of proteomics remains unclear. Here, we examine the associations of cardiovascular health (CVH) score and degree of risk factor control with common diabetic complications using data from the UK Biobank (n = 14,102). Furthermore, we explore the mediation effects of plasma proteomics in a subset with proteomic data (n = 1287). Over median follow-ups of 12.4-13.4 years, higher CVH score and higher degree of risk factor control are associated with lower risks of 30 and 22 of 45 adverse outcomes among individuals with T2D, respectively. Mediation analyses reveal that mortality and multiple vascular diseases share common mediators, such as uromodulin and pro-adrenomedullin. These findings highlight the importance of risk factors modification in reducing disease burden among people with T2D and facilitate the understanding of mediation effects of plasma proteins underlying these associations.

Effect of luseogliflozin on liver fibrosis differs depending on alcohol consumption in patients with type 2 diabetes

AIM

Changes in FIB-4 levels after the initiation of luseogliflozin therapy were compared between patients with type 2 diabetes according to the presence or absence of alcohol consumption.

METHODS

A total of 192 patients with type 2 diabetes who continued luseogliflozin therapy for over 12 months were retrospectively investigated. The primary outcome was the change in FIB-4. The secondary outcomes were changes in HbA1c, body weight, and serum albumin concentration. A current drinker was defined as an individual consuming >20 g ethanol equivalent/day. Patients were classified according to their risk of developing liver fibrosis into the low-risk (FIB-4 < 1.3) and intermediate/high-risk (FIB-4 ≥ 1.3) groups.

RESULTS

In the low-risk group, while FIB-4 increased dramatically from 0.91 ± 0.30 at the baseline to 1.14 ± 0.34 at 12 months in drinkers (n = 27), non-drinkers (n = 79) showed no significant change (0.87 ± 0.22-0.91 ± 0.26). In the intermediate/high-risk group (n = 63), although the FIB-4 in drinkers (n = 23) showed no significant change (2.18 ± 1.00-2.16 ± 0.93), it significantly decreased from 2.10 ± 0.87 to 1.80 ± 0.68 in non-drinkers (n = 63). In both the low- and intermediate/high-risk groups, HbA1c and body weight significantly decreased in both drinkers and non-drinkers. Serum albumin concentrations significantly increased in both drinkers and non-drinkers in the low-risk group. Although serum albumin concentration did not significantly change in drinkers, it dramatically increased in non-drinkers in the intermediate/high-risk group.

CONCLUSIONS

HbA1c levels and body weight decreased in patients with type 2 diabetes after initiating luseogliflozin therapy, regardless of drinking habits. However, it is desirable to limit alcohol consumption when considering its effects on liver fibrosis.

Spatial histomorphometry reveals that local peripheral nerves modulate but are not required for skeletal adaptation to applied load in mice

Mechanical loading is required for bone health and results in skeletal adaptation to optimize strength. Local nerve axons, particularly within the periosteum, may respond to load-induced biomechanical and biochemical cues. However, their role in the bone anabolic response remains controversial. We hypothesized that spatial alignment of periosteal nerves with sites of load-induced bone formation would clarify this relationship. To achieve this, we developed RadialQuant, a custom tool for spatial histomorphometry. Tibiae of control and neurectomized (sciatic/femoral nerve cut) pan-neuronal Baf53b-tdTomato reporter mice were loaded for 5 days. Bone formation and periosteal nerve axon density were then quantified simultaneously in non-decalcified sections of the mid-diaphysis using RadialQuant. In control animals, anabolic loading induced maximal periosteal bone formation at the site of peak compression, as has been reported previously. By contrast, loading did not significantly change overall periosteal nerve density. Neurectomy depleted ~90% of all periosteal axons, with near-total depletion on load-responsive surfaces. Neurectomy alone also caused de novo bone formation on the lateral aspect of the mid-diaphysis. However, neurectomy did not inhibit load-induced increases in periosteal bone area, mineralizing surface, or bone formation rate. Rather, neurectomy spatially redistributed load-induced bone formation toward the lateral tibial surface with a reduction in periosteal bone formation at the posterolateral apex (-63%) and enhancement at the lateral surface (+1360%). Altogether, this contributed to comparable load-induced changes in cortical bone area fraction. Our results show that local skeletal innervation modulates but is not required for skeletal adaptation to applied load in our model. This supports the continued use of loading and weight-bearing exercise as an effective strategy to increase bone mass, even in settings of peripheral nerve damage or dysfunction.

Anemia in diabetes mellitus: Pathogenetic aspects and the value of early erythropoietin therapy

Anemia is a frequent, yet increasingly recognized, comorbidity in diabetes mellitus (DM), with prevalence often driven by multifactorial mechanisms. Hematinic deficiencies, common in this population, may arise from associated comorbidities or medications, such as metformin, as well as other drugs commonly employed for DM-related conditions. Among contributing factors, diabetic kidney disease (DKD) plays a pivotal role, with anemia developing more frequently and being more pronounced in earlier stages, than in CKD of other causes. This enhanced susceptibility stems primarily from the combined impact of impaired renal oxygen sensing and deficient erythropoietin (EPO) production linked to tubulointerstitial fibrosis. Additional mechanisms comprise glomerular dysfunction, shortened erythrocyte lifespan, uremia-induced bone marrow suppression, and increased bleeding risk. DM is also recognized as a chronic low-grade inflammatory condition, with its inflammatory burden driving iron maldistribution, suppression of erythropoiesis, and resistance to EPO. The diagnostic approach of anemia in DM mirrors that in the general population. Addressing modifiable causes such as hematinic deficiencies, and other chronic conditions, such as DKD and bone marrow disorders, is paramount. In total, the underlying pathophysiology of anemia in DM primarily reflects a state of absolute or relative EPO deficiency and/or diminished bone marrow responsiveness, effectively corresponding to 'anemia of chronic disease. Early initiation of EPO therapy, even in DM patients without overt DKD, may mitigate disease progression and improve outcomes. Future research should focus on diabetes-specific strategies integrating optimal EPO use, potentially implementing targeted management of renal and inflammatory contributors to anemia.

Barriers and new opportunities in developing effective therapies for diabetic neuropathy: International expert consensus recommendations

BACKGROUND

Diabetic neuropathy (DN) affects up to half of individuals with type 1 and type 2 diabetes. Despite evidence that improving metabolic and cardiovascular health can slow its progression, DN remains a significant clinical challenge due to the lack of disease-modifying therapies and effective pain management strategies. This consensus aimed to identify gaps and recommend strategies to address these challenges.

METHOD

A workshop, initiated by Steno Diabetes Centre Copenhagen and the Danish Diabetes and Endocrinology Academy, conducted a gap analysis based on insights from clinical studies, observational cohorts, and clinical practice. Online invitations targeted experienced clinicians, researchers, and drug developers committed to improving DN treatment through innovative clinical trials. Thirty-five participants from six countries reached consensus via a Delphi process on key steps to advance DN therapy.

RESULT

Four critical barriers and needs were addressed: (1) Translating bench research to clinical practice, (2) Enhancing clinical trial design, (3) Improving outcome measures, and (4) Identifying effective treatments for painful DN.

CONCLUSION

Successful interventional trials require robust outcome measures to capture clinically meaningful changes in DN phenotypes, providing the basis for developing effective, disease-modifying treatments.

Challenges, current innovations, and opportunities for managing type 2 diabetes in frail older adults: a position paper of the European Geriatric Medicine Society (EuGMS)-Special Interest Group in Diabetes

PURPOSE

This position paper aims to address the challenges of managing type 2 diabetes mellitus (T2DM) in frail older adults, a diverse and growing demographic with significant variability in health status. The primary research questions are: How can frailty assessment be effectively integrated into diabetes care? What strategies can optimize glycaemic control and outcomes for frail older adults? How can innovative tools and technologies, including artificial intelligence (AI), improve the management of this population?

METHODS

The paper uses the 5 I's framework (Identification, Innovation, Individualization, Integration, Intelligence) to integrate frailty into diabetes care, proposing strategies such as frailty tools, novel therapies, digital technologies, and AI systems. It also examines metabolic heterogeneity, highlighting anorexic-malnourished and sarcopenic-obese phenotypes.

RESULTS

The proposed framework highlights the importance of tailoring glycaemic targets to frailty levels, prioritizing quality of life, and minimizing treatment burden. Strategies such as leveraging AI tools are emphasized for their potential to enhance personalized care. The distinct management needs of the two metabolic phenotypes are outlined, with specific recommendations for each group.

CONCLUSION

This paper calls for a holistic, patient-centered approach to diabetes care for frail older adults, ensuring equity in access to innovations and prioritizing quality of life. It highlights the need for research to fill evidence gaps, refine therapies, and improve healthcare integration for better outcomes in this vulnerable group.

Glycemic, Cardiorenal, and Weight Implications on Noninsulin Pharmacotherapy for the Management of Type 2 Diabetes

CONTEXT

The incidence of diabetes is growing at an alarming rate globally. Most of these projected individuals will develop type 2 diabetes (T2DM), raising their risk of cardiovascular disease and chronic kidney disease. This mini-review examines current noninsulin and noninjectable pharmacotherapy focused in T2DM, highlighting the effect on glycemic control and importance of cardiovascular and renal outcomes.

EVIDENCE ACQUISITION

We included population level data and searched the PubMed database for recent systematic reviews, meta-analyses, and original research articles.

EVIDENCE SYNTHESIS

There is a pharmacologic menu of noninsulin-based medications for the treatment of diabetes. Through varying mechanisms, all agents ultimately lead to glycemic improvement to varying degrees. Only a select number of agents are shown to improve important clinical cardiovascular and renal outcomes. Of note, sodium-glucose cotransporter-2 inhibitors have improved cardiovascular mortality and time to dialysis in people with diabetes. Likewise, incretin-based therapies have improved important cardiovascular and renal composite outcomes in those with diabetes and cardiovascular disease. As a result, agents with proven cardiovascular and renal benefits should be prioritized based on patient risk.

CONCLUSION

Despite the availability of new medications and technology, published clinical guidelines, and treatment algorithms, most people with diabetes remain above glycemic targets. We encourage clinicians to follow the guidelines and use appropriate medications to lower cardiovascular risk, delay progression of chronic kidney disease, reach glycemic targets, and manage weight.

Assessing Current Knowledge of Hearing Impairment With Diabetes by Surveying Providers With CBDCE Certification

PURPOSE

The purpose of this study was to assess current knowledge, attitudes, and practices regarding hearing impairment and screening referrals in patients with diabetes among providers who have a Certified Diabetes Care and Education Specialist (CBDCE) Certification.

METHODS

A cross-sectional survey created through Qualtrics was emailed to health care providers in the United States with CDCES certification. Providers responded regarding knowledge and importance of hearing impairment compared to other diabetes complications, when they would refer a patient to an audiologist, the percentage of patients referred, and awareness of over-the-counter hearing aids. Descriptive statistics were calculated for all questionnaire items.

RESULTS

One thousand four hundred and ninety-five CDCES providers completed the survey. Participants selected the most common conditions associated with diabetes as kidney dysfunction (96.7%), retinopathy (96.5%), obesity (95.6%), and foot infection (94.5%); 44.5% chose hearing impairment. Over 60% of providers were not familiar with how to refer patients to an audiologist and acknowledged being unfamiliar with recommended screening frequency as the most common barrier. Most providers had referred fewer than 20% of patients to an audiologist. Over half of providers were not aware of over-the-counter hearing aids.

CONCLUSION

Among a national sample of health care providers with comprehensive knowledge in diabetes care, many providers do not associate hearing impairment with diabetes and rate other microvascular complications of higher importance.

Cognitive dysfunction in diabetes - the 'forgotten' diabetes complication: a narrative review

BACKGROUND

In addition to peripheral neuropathy of various kinds, diabetes can also cause central neuropathy, which among other things can manifest itself as premature cognitive dysfunction, often linked to vascular dysfunction. Although the link between diabetes and cognitive dysfunction was discovered more than 100 years ago and has important clinical implications, this diabetes complication remains relatively unknown. Recent years have seen research that has clarified cerebral insulin resistance and defective insulin signaling as examples of pathogenic factors behind this cognitive impairment in diabetes.

METHOD

We provide a narrative review of select and contemporary publications with relevance for the interface between diabetes/prediabetes and cognitive function.

RESULTS

Recently published studies show that physical activity can reverse insulin resistance in the brain as well as cognitive impairment and pathological appetite regulation. Pharmacological interventions with, for example, nasal insulin, GLP-1 receptor agonists, SGLT-2 inhibitors, or PPAR-γ agonists have also shown promising results.

CONCLUSION

Optimization of lifestyle factors (e.g. physical activity), as well as several pharmaceutical agents already in clinical use against diabetes, have shown promising results in improving cognitive function in diabetic patients. An important task for primary health care, where most patients with type 2 diabetes are diagnosed, treated, and followed, is to increase awareness and early detection of cognitive dysfunction in these patients for optimizing risk factor control.

Addressing Diabetes Distress in Primary Care: Where Are We Now, and Where Do We Need to Go?

PURPOSE OF REVIEW

Addressing diabetes distress (DD), the emotional demands of living with diabetes, is a crucial component of diabetes care. Most individuals with type 2 diabetes and approximately half of adults with type 1 diabetes receive their care in the primary care setting. This review will provide guidance on addressing DD and implementing targeted techniques that can be tailored to primary care patients.

RECENT FINDINGS

Structured educational, behavioral, and emotion-focused techniques have promise for treating DD. These interventions are unlikely to require advanced training and can be feasibly integrated into primary care settings without creating additional burdens on time or resources. Interventional studies examining treatment for DD are limited, leaving a gap for clear direction and consensus on how to target and treat DD in primary care patients. This review consolidates recommendations and approaches from recent findings on how to treat DD within the context of primary care.

Unveiling Silent Atherosclerosis in Type 1 Diabetes: The Role of Glycoprotein and Lipoprotein Lipidomics, and Cardiac Autonomic Neuropathy

Introduction: This study aimed to evaluate whether glycoprotein and lipoprotein lipidomics profiles could enhance a clinical predictive model for carotid subclinical atherosclerosis in patients with type 1 diabetes (T1D). Additionally, we assessed the influence of cardiac autonomic neuropathy (CAN) on these predictive models. Methods: We conducted a cross-sectional study including 256 patients with T1D. Serum glycoprotein and lipoprotein lipidomics profiles were determined using 1H-NMR spectroscopy. Subclinical atherosclerosis was defined as carotid intima-media thickness (cIMT) ≥ 1.5 mm. CAN was identified using the Clarke score. Predictive models were built and their performance evaluated using receiver operating characteristic curves and cross-validation. Results: Subclinical atherosclerosis was detected in 32% of participants. Patients with both CAN and atherosclerosis were older, had a longer duration of diabetes, and were more likely to present with bilateral carotid disease. Clinical predictors such as age, duration of diabetes, and smoking status remained the strongest determinants of subclinical atherosclerosis [AUC = 0.88 (95%CI: 0.84-0.93)]. While glycoprotein and lipoprotein lipidomics profiles were associated with atherosclerosis, their inclusion in the clinical model did not significantly improve its diagnostic performance. Stratification by the presence of CAN revealed no impact on the model's ability to predict subclinical atherosclerosis, underscoring its robustness across different risk subgroups. Conclusions: In a cohort of patients with T1D, subclinical atherosclerosis was strongly associated with traditional clinical risk factors. Advanced glycoprotein and lipoprotein lipidomics profiling, although associated with atherosclerosis, did not enhance the diagnostic accuracy of predictive models beyond clinical variables. The predictive model remained effective even in the presence of CAN, highlighting its reliability as a screening tool for identifying patients at risk of subclinical atherosclerosis.

Pan-PPAR agonist lanifibranor improves insulin resistance and hepatic steatosis in patients with T2D and MASLD

BACKGROUND & AIMS

Lanifibranor is a pan-PPAR agonist that improves glucose/lipid metabolism and reverses steatohepatitis and fibrosis in adults with metabolic dysfunction-associated steatohepatitis (MASH). We tested its effect on insulin resistance (IR) at the level of different target tissues in relation to changes in intrahepatic triglyceride (IHTG) content.

METHODS

In this single-center phase II study, 38 patients with type 2 diabetes and MASLD were randomized 1:1 to receive lanifibranor 800 mg or placebo for 24 weeks. The primary endpoint was the change in IHTG (1H-MRS). The main prespecified secondary endpoint was the change in hepatic, muscle and adipose tissue insulin sensitivity using the gold-standard euglycemic hyperinsulinemic clamp technique to measure glucose turnover. Other secondary endpoints included changes in cardiometabolic parameters (i.e., HbA1c, lipid profile, adiponectin).

RESULTS

Lanifibranor significantly lowered IHTG compared to placebo (full analysis set [FAS] -44% vs. -12%, respectively; least squares mean difference -31%, 95% CI -51 to -12%; in completers -50% vs. -16%; both p <0.01). More patients in the lanifibranor group (vs. the placebo group) achieved a ≥30% IHTG reduction (FAS 65% vs. 22%; completers 79% vs. 29%; both p <0.01) and steatosis resolution (FAS 25% vs. 0%; p <0.05). Lanifibranor significantly improved hepatic and peripheral IR (i.e. fasting endogenous [primarily hepatic] glucose production, hepatic IR, and insulin-stimulated muscle glucose disposal or Rd). Secondary metabolic endpoints also improved (fasting glucose, insulin, HOMA-IR, HbA1c, HDL-C), and adiponectin increased 2.4-fold (all p <0.001). Lanifibranor caused modest weight gain (+2.7%). Adverse events were mild (gastrointestinal side effects, hemoglobin decrease) and drug-related treatment-emergent adverse events leading to study discontinuation were balanced between groups.

CONCLUSIONS

Lanifibranor significantly improves hepatic, muscle and adipose tissue IR. Lanifibranor treatment was safe and effective in reducing hepatic steatosis and cardiometabolic risk factors associated with metabolic dysfunction.

IMPACT AND IMPLICATIONS

No prior studies have evaluated the effect of lanifibranor on insulin sensitivity at the level of muscle, liver and adipose tissue and its relationship to changes in intrahepatic triglyceride (IHTG) content in insulin-resistant individuals with metabolic dysfunction-associated steatotic liver disease (MASLD) and type 2 diabetes. We observed a significant decrease in IHTG after 24 weeks of treatment (by ∼50%, p <0.001 vs. placebo) that was associated with a major improvement in hepatic and peripheral (Rd) insulin sensitivity, restoration of adipose tissue function and improvement in cardiometabolic risk factors. This study has important clinical implications because it offers proof-of-concept that targeting the key underlying metabolic defects in MASLD (i.e. insulin resistance, lipotoxicity and hyperglycemia) can restore cardiometabolic health. It offers a compelling rationale for lanifibranor treatment in individuals with MASLD, either alone or in combination with weight loss and other treatment strategies.

Diabetes and cardiovascular disease in older adults

An aging population combined with a rapidly increasing prevalence of diabetes foreshadows a global epidemic of cardiovascular and kidney disease that threatens to halt improvements in life and health-span and will have particularly severe consequences in older adults. The management of diabetes has been transformed with the recent development of newer anti-hyperglycemic agents that have demonstrated superior efficacy. However, the utility of these drugs extends beyond glycemic control to benefits for managing obesity, cardiovascular disease (CVD), chronic kidney disease, and heart failure. Numerous cardiovascular and kidney outcomes trials of these drugs have played an instrumental role in shaping current guidelines for the management of diabetes and CVD. Older adults with diabetes are diverse in terms of their comorbidities, diabetic complications, and cognitive and functional status. Therefore, there is an unmet need for personalized management of diabetes and CVD in this population. In this review, we provide an overview of the epidemiological burden and management of diabetes and CVD in older adults. We then focus on randomized cardiovascular and kidney outcome trials with anti-hyperglycemic agents to propose an evidence-based approach to the management of diabetes in older adults with high risk of cardiovascular and kidney disease.

Prevalence of Osteoporosis in Postmenopausal Type 2 Diabetic Women with Diabetic Peripheral Neuropathy

Introduction

There is evidence that diabetic peripheral neuropathy (DPN) is associated with increased risk for fractures in type 2 diabetes mellitus (T2DM). We planned a study to assess the prevalence of osteoporosis and vertebral fractures (VFs) in postmenopausal type 2 diabetic women aged 40-60 years with DPN and to find out their relationship with severity of DPN.

Methods

This cross-sectional observational study included sixty-two postmenopausal type 2 diabetic women of age 40-60 years, out of them thirty-two were with DPN and thirty were without DPN. The presence of DPN was established based on history and clinical examination. Plain X-ray spine and bone mineral density (BMD) measured by dual-energy X-ray absorptiometry were used to assess vertebral fracture and osteoporosis, respectively.

Results

The prevalence of osteoporosis in women with DPN was 68.75% at lumbar spine (LS) and 18.75% at femoral neck (FN), and osteoporosis at LS was statistically significant compared to those without DPN (P = 0.002). On subgroup analysis in women with DPN, the osteoporosis at LS showed significant association with lower body mass index (BMI) (P = 0.015), but not with severity of DPN. The prevalence of VFs in women with DPN was 6.25% with no statistical significance in comparison with other group.

Conclusion

Our study revealed high prevalence of osteoporosis at LS in postmenopausal type 2 diabetics with DPN. VFs are most common consequence of osteoporosis, although we could not find significant prevalence of VFs in women with DPN that may be due to small sample size and cross-sectional study design.

Metabolic Dysfunction-Associated Steatotic Liver Disease

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease in the United States. It is characterized by steatosis in the liver and is potentially reversible. Risk factors include obesity, type 2 mellitus, and other metabolic disorders. Metabolic dysfunction-associated steatohepatitis (MASH), a more severe form of MASLD, puts patients at risk for cirrhosis, liver decompensation, and liver cancer. Diet, exercise, and weight loss are the cornerstones of management. Although only 1 medication has been approved for treatment of MASH, other pharmacotherapies and surgeries that aid weight loss and optimize metabolic risk factors can be used. Early diagnosis and intervention are important to prevent progression to cirrhosis and its complications, including cancer.

Multimorbidity in elderly patients with or without T2DM: A real-world cross-sectional analysis based on primary care and hospitalisation data

Background

Shanghai's high level of ageing has given rise to a considerable number of elderly patients with type 2 diabetes mellitus (T2DM) who are confronted with the challenge of managing multimorbidity. We aimed to determine the prevalence of multimorbidity in elderly T2DM patients in a representative Pudong New Area community and critically evaluate current guidelines' inclusiveness in addressing major comorbidities.

Methods

Through the Shanghai Health Cloud platform, we extracted medical records of residents in the Huamu community (Pudong New Area, Shanghai) to screen elderly patients with at least three outpatient visits or one hospitalisation per year between 2019 and 2022. According to International Classification of Disease, 10th edition codes and personal identification number, we identified the status of T2DM and 12 other common chronic diseases, matched T2DM patients and non-T2DM patients 1:1 by age and gender, and then calculated the prevalence of multimorbidity status and annual prevalence of each comorbidity. We analysed associations between T2DM and specific chronic diseases using logistic regression models.

Results

More than 90% of elderly T2DM patients had at least one additional chronic disease. Multimorbidity was more frequent in women and older patients. Hyperlipidemia, hypertension, and ischaemic heart disease were the most prevalent comorbidities. The diagnosis of T2DM was significantly associated with both cardiovascular-kidney-metabolic and neuropsychiatric diseases. In addition, a higher prevalence and risk of chronic obstructive pulmonary disease (COPD) were consistently detected in elderly patients with T2DM, regardless of age and gender.

Conclusions

Multimorbidity in elderly patients with T2DM needs broader acknowledgement. Current guidelines focus more on cardiovascular-kidney-metabolic and neuropsychiatric diseases with inadequate guidance on COPD management. Hence, the pleiotropic effects of glucose-lowering drugs on COPD should be further investigated to optimise the comprehensive management strategy for this population.

Using Panel Management to Identify Adult Patients With High-Risk Metabolic Dysfunction-Associated Steatotic Liver Disease/Metabolic Dysfunction-Associated Steatohepatitis Fibrosis in a Primary Care Clinic: A Pilot Study

BACKGROUND

As rates of metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH) rise, national organizations have released new guidance for primary care-driven detection of patients with advanced fibrosis who are most likely to have clinically relevant morbidity. Yet time constraints, workflow, and practitioner awareness limit integration of risk identification into clinical care.

MATERIALS AND METHODS

At the authors' primary care clinic, they implemented a panel management strategy that utilized the electronic health record to identify patients older than 35 years of age at risk for MASLD fibrosis with abnormal Fibrosis-4 (Fib-4) scores. Using a proactive model, these patients were offered elastography-based screening and follow-up appointments focused on metabolic health, with referrals to subspecialty care when indicated.

RESULTS

Of 855 patients older than 35 years of age, 384 were identified as having risk factors for MASLD/MASH. Of these, 53 had abnormal Fib-4 scores with no prior work-up; 29 patients consented to a shear wave elastography; 16 underwent shear wave elastography; and 6 had moderate or high results concerning for at-risk fibrosis. Twenty patients attended MASLD-focused appointments. Reluctance to pursue testing was driven by skepticism surrounding preventative medicine, perceived cost, and desire to focus on other medical problems, some of which were life-limiting.

CONCLUSION

Panel management represents a scalable strategy to quickly identify patients in primary care most likely to experience complications from MASLD/MASH and provides a targeted intervention to direct further management. Limitations include access to care, medical complexity, and patient acceptance.

Impact of GLP-1 Receptor Agonist Use in Patients With Steatotic Liver Disease and Type 2 Diabetes: A Retrospective Cohort Study

Background: Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) help manage type 2 diabetes (T2DM) and may have efficacy in steatotic liver disease. Objective: To determine the prevalence and clinical impact of GLP-1 RA use in patients with T2DM and liver disease. Methods: This was a retrospective study of adult patients with T2DM and nonalcoholic fatty liver disease (NAFLD), nonalcoholic fatty liver (NAFL), or nonalcoholic steatohepatitis (NASH) between 1/1/21-12/31/21. Patients with hepatitis B or C, or on pioglitazone were excluded. Eligible patients treated with a GLP-1 RA were compared to controls. The primary outcome was change in Fibrosis-4 (FIB-4) score, with NAFLD Fibrosis Score (NFS) as a secondary outcome. Follow-up scores were calculated from labs within 3 to 15 months after baseline. Results: Of 242 eligible patients, 79 patients (32.6%) were treated with a GLP-1 RA. At baseline, FIB-4 score was lower and NFS was higher in the GLP-1 RA group vs controls (1.80 vs 2.33; P = .101, .36 vs -.47, P < .001; respectively). At follow up, FIB-4 score decreased to 1.77 in the GLP-1 RA group and increased to 2.71 in controls (P = .045). Follow up NFS was stable in the GLP-1 RA group and increased in the control group (.36 vs -.43; P = .308). Conclusion: Patients treated with GLP-1 RAs had less evidence of liver fibrosis progression compared to no treatment, although the differences were small. These results suggest that treatment with GLP-1 RAs may have clinical impact on slowing liver fibrosis, however results should be confirmed in a larger, more diverse sample.

Multidisciplinary stakeholder engagement in a type 2 diabetes comparative effectiveness study utilizing real-world data

Introduction

Patient and stakeholder involvement enhances the conduct and applicability of comparative effectiveness research (CER). However, examples of engagement practices for CER leveraging real-world data (i.e., data from routine clinical practice) are scarce. Notably, these studies differ from traditional clinical trials in their technical complexity and minimal prospective data collection, posing unique challenges for stakeholder involvement. This paper describes patient and stakeholder engagement in a CER study of type 2 diabetes (T2D) medications using real-world data from a large administrative claims database.

Methods

A Patient and Stakeholder Advisory Group (PSAG) was formed to guide study design, conduct, and dissemination. The PSAG (n = 12) included individuals with T2D, clinicians, health systems leaders, professional society representatives, and a payer representative. Members were surveyed post-study initiation to assess their participation goals and experiences to date.

Results

PSAG members influenced key design and methodological decisions, including cohort selection and adding an aim focused on patient preference elicitation. Survey results indicated high satisfaction with engagement processes and a desire for ongoing involvement. Most PSAG members cited their main goals as impacting the lives of people with T2D and ensuring the research's relevance to clinicians.

Conclusions

Best practices for engaging stakeholders in CER using real-world data are underdeveloped. Our experience suggests that an inclusive, stakeholder-engaged approach enriches the research process and ensures diverse perspectives are integrated into study design and conduct. Ongoing efforts will focus on assessing long-term engagement outcomes and PSAG member satisfaction.

Is physical fitness associated with leucocyte telomere length in youth with type 1 diabetes?

BACKGROUND

In type 1 diabetes, telomere length (TL) may predict complications and could be influenced by glycaemic control and physical activity, but its relationship with physical fitness in youths remains unexplored. The aim of the study was to assess the association between physical fitness and TL in youth with type 1 diabetes, both at baseline and one year later.

METHODS

Eighty-three children and adolescents (aged 6-18 years; 44.6% girls) with type 1 diabetes from the Diactive-1 Cohort Study were involved in this study. Physical fitness was assessed using spirometry on a cycloergometer (i.e., peak oxygen consumption), dynamometry, and maximal isometric strength (one-repetition maximum [1RM]), and muscle power. Leucocyte TL was assessed using multiplex monochrome real-time quantitative polymerase chain reaction.

RESULTS

Positive cross-sectional associations were identified between 1RM (unstandardized beta coefficient [B] = 0.042, 95% bias corrected and accelerated [BCa] confidence interval [CI] 0.012-0.069), muscle power (B = 0.056, 95% BCa CI 0.02-0.250), and overall physical fitness (B = 0.043, 95% BCa CI 0.015-0.071) with TL independent of maturation, glycated haemoglobin, and diabetes duration. However, no associations were observed one year later.

CONCLUSION

Higher levels of fitness, particularly muscle strength, may play a role in telomere dynamics in youth with type 1 diabetes, suggesting that strength training exercise could be beneficial.

IMPACT

This is the first study to examine cross-sectional and longitudinal perspectives on the correlation among muscle strength, peak oxygen consumption [VO2peak] and telomere length in youths with type 1 diabetes. Higher physical fitness levels, as assessed by measures such as one-repetition maximum, muscle power, and overall physical fitness, are positively associated with telomere length in youths with type 1 diabetes. Understanding this link could improve management strategies, prioritizing muscle strength training for better long-term health in type 1 diabetes.

Real-World HbA1c Changes Among Type 2 Diabetes Mellitus Patients Initiating Treatment With a 1.0 Mg Weekly Dose of Semaglutide for Diabetes

Background: Medical management of patients with type 2 diabetes mellitus (T2DM) is complex because of the chronic nature of the disease and its associated comorbidities. Injectable once-weekly semaglutide for diabetes (OW sema T2D) is a type of glucagon-like peptide-1 receptor agonist approved for the treatment of patients with T2DM. Objectives: To describe patient characteristics and HbA1c changes for patients prescribed 1.0 mg maintenance dose OW sema T2D. Methods: This retrospective study included adult patients with T2DM with a pre-index glycated hemoglobin (HbA1c) of at least 7%, initiating treatment with OW sema T2D between January 1, 2018, and December 31, 2019, and prescribed a 1.0 mg maintenance dose. Patients were identified in the Optum Research Database and were included if they had continuous health plan enrollment for at least 12 months prior to (pre-index) and at least 12 months following (post-index) the date of the first OW sema T2D claim (index). Dose at initiation and prescriber specialty were captured. Change in HbA1c between the latest post-index and pre-index HbA1c measurement was calculated among all patients and among those with at least 90 days of continuous treatment (persistent patients). Results: A total of 2168 patients were included in this study. On average, patients were taking 13.5 different classes of medications. The majority of patients had lipid metabolism disorder (90.8%), hypertension (86.6%), diabetes with complications (86.8%), or other nutritional/endocrine/metabolic disorders (72.5%). The mean HbA1c reduction was 1.2% (P < .001). Patients persistent with OW sema T2D (n =1280) had a mean HbA1c reduction of 1.4% (P < .001). The mean (SD) days covered with a 1.0 mg maintenance dose was 236.1 (94.1) days. Discussion: Despite being medically complex, the patients in this real-world study experienced significant reductions in HbA1c following initiation of OW sema T2D. Conclusions: A 1.0 mg maintenance dose of OW sema T2D is an effective treatment for T2DM in the real world.

Bidirectional association between inflammatory bowel disease and type 1 diabetes: a nationwide matched cohort and case-control study

Background

Co-occurrence of inflammatory bowel disease (IBD) and type 1 diabetes (T1D) has been linked to poor clinical outcomes, but evidence on their bidirectional associations remain scarce. This study aims to investigate their bidirectional associations.

Methods

A nationwide matched cohort and case-control study with IBD patients identified between 1987 and 2017. The cohort study included 20,314 IBD patients (≤28 years; Crohn's disease [CD, n = 7277], ulcerative colitis [UC, n = 10,112], and IBD-unclassified [IBD-U, n = 2925]) and 99,200 individually matched reference individuals, with a follow-up until December 2021. The case-control study enrolled 87,001 IBD patients (no age restriction) and 431,054 matched controls. We estimated adjusted hazard ratio (aHR) of incident T1D in the cohort study with flexible parametric survival model and adjusted odds ratio (aOR) of having a prior T1D in the case-control study with conditional logistic regression model, with 95% confidence intervals (CI).

Findings

During a median follow-up of 14 years, 116 IBD patients and 353 reference individuals developed T1D. Patients with IBD had a higher hazard of developing T1D (aHR = 1.58 [95% CI = 1.27-1.95]). The hazard was increased in UC (aHR = 2.02 [1.51-2.70]) but not in CD or IBD-U. In the case-control study, a total of 1018 (1.2%) IBD patients and 3496 (0.8%) controls had been previously diagnosed with T1D. IBD patients had higher odds of having prior T1D (aOR = 1.36 [1.26-1.46]). Such positive association was observed in all IBD subtypes. The sibling comparison analyses showed similar associations between IBD and T1D (aHR = 1.44 [0.97-2.15] and aOR = 1.32 [1.18-1.49]).

Interpretation

Patients with IBD had a moderately increased hazard of developing T1D and higher odds of having prior T1D. Their bidirectional associations may be partially independent of shared familial factors.

Key Challenges to Understanding the Burden of Respiratory Syncytial Virus in Older Adults in Southeast Asia, the Middle East, and North Africa: An Expert Perspective

INTRODUCTION

Respiratory syncytial virus (RSV) is a common, highly contagious pathogen and a leading cause of serious illness among infants and older adults. While existing scientific evidence has predominantly focused on the epidemiology and disease burden of RSV in infants, data in older adults remain limited in some countries, including those in Southeast Asia (SEA) and the Middle East and North Africa (MENA) region. Here, we outline the key challenges for understanding the burden of RSV in older adults in SEA and the MENA region and we propose opportunities for improving understanding and eventually reducing the impact of RSV.

MAIN FINDINGS AND CONCLUSIONS

A key challenge identified by the expert group, particularly in older adults, is a lack of awareness (among healthcare professionals, policy makers, and the public) of RSV burden and the associated risks for severe outcomes. This is often confounded by the complexities of underdiagnosis, surveillance limitations, and comorbidities. To address these issues, we suggest medical education initiatives for physicians in SEA and the MENA region to better understand the need to protect older adults from RSV, and encourage more widespread routine testing to better understand the burden of RSV. We also recommend surveillance studies in these regions to provide comprehensive and accurate epidemiological data on RSV in older adults. Finally, in the absence of current surveillance data in these regions, we propose extrapolating existing global data and local pediatric data to inform the likely burden of RSV in older adults.

Efficacy, tolerability and pharmacokinetics of survodutide, a glucagon/glucagon-like peptide-1 receptor dual agonist, in cirrhosis

BACKGROUND & AIMS

Survodutide is a glucagon/glucagon-like peptide-1 receptor dual agonist in development for the treatment of metabolic dysfunction-associated steatohepatitis (MASH). We investigated the pharmacokinetic and safety profile of survodutide in people with cirrhosis.

METHODS

This multinational, non-randomized, open-label, phase I clinical trial initially evaluated a single subcutaneous dose of survodutide 0.3 mg in people with Child-Pugh class A, B or C cirrhosis and healthy individuals with or without overweight/obesity matched for age, sex, and weight; the primary endpoints were the area under the plasma concentration-time curve from 0 to infinity (AUC0-∞) and maximal plasma concentration (Cmax). Subsequently, people with overweight/obesity with or without cirrhosis (Child-Pugh class A or B) received once-weekly subcutaneous doses escalated from 0.3 mg to 6.0 mg over 24 weeks then maintained for 4 weeks; the primary endpoint was drug-related treatment-emergent adverse events, with MASH/cirrhosis-related endpoints explored.

RESULTS

In the single-dose cohorts (n = 41), mean AUC0-∞ and Cmax were similar in those with cirrhosis compared with healthy individuals (90% CIs for adjusted geometric mean ratios spanned 1). Drug-related adverse events occurred in 25.0% of healthy individuals and ≤25.0% of those with cirrhosis after single doses, and 82.4% and 87.5%, respectively, of the multiple-dose cohorts (n = 41) over 28 weeks. Liver fat content, liver stiffness, liver volume, body weight, and other hepatic and metabolic disease markers were generally reduced after 28 weeks of survodutide treatment.

CONCLUSIONS

Survodutide is generally tolerable in people with compensated or decompensated cirrhosis, does not require pharmacokinetic-related dose adjustment, and may improve liver-related non-invasive tests, supporting its investigation for MASH-related cirrhosis.

IMPACT AND IMPLICATIONS

Survodutide is a glucagon receptor/glucagon-like peptide-1 receptor dual agonist in development for treatment of metabolic dysfunction-associated steatohepatitis (MASH), which causes cirrhosis in ∼20% of cases. This trial delineates the pharmacokinetic and safety profile of survodutide in people with compensated or decompensated cirrhosis, and revealed associated reductions in liver fat content, markers of liver fibrosis and body weight. These findings have potential relevance for people with MASH-including those with decompensated cirrhosis, who are usually excluded from clinical trials of investigational drugs. Based on this study, further investigation of survodutide for MASH-related cirrhosis is warranted.

Intervening on Metabolic Dysfunction-Associated Steatotic Liver Disease in Latino/a and Black Patients with Diabetes: A Feasibility Pilot

INTRODUCTION

Patients with type 2 diabetes (T2D), particularly those from historically marginalized racial and ethnic groups, are at high risk of poor outcomes from metabolic dysfunction-associated steatotic liver disease (MASLD). Evidence-based management (EBM) of MASLD can prevent its progression to cirrhosis and poor outcomes, yet rates of EBM of MASLD are low in T2D.

METHODS

In this pilot study of ten participants, we examined the feasibility and acceptability of a telehealth intervention that delivered EBM of MASLD in Latino/a and Black patients with T2D in the Duke Healthcare System. The intervention included: (a) MASLD education; (b) diet/lifestyle counseling; (c) T2D medication adjustment (i.e., to promote liver health) and (d) ordering of clinically indicated tests and referrals. This 3-month intervention was delivered by an endocrinologist over three virtual study visits. Phone interviews were conducted at study conclusion. We examined rates of recruitment, retention, T2D medication adjustment, and ordering of clinically indicated tests/referrals.

RESULTS

The median age of our cohort was 54.0 (44.0, 59.0); six and four participants self-identified as Latino/a ethnicity and Black race, respectively. Retention rate in this study was 100% (n = 10/10), and all scheduled visits were completed (n = 30/30). Recruitment occurred over one month, and the rate was 25.8% (n = 8/31) by telephone call and 10% (n = 2/20) by electronic health record message. The intervention was highly acceptable based on a median Treatment Acceptability and Preferences score of 4.0 (4.0, 4.0). In exit interviews, all participants reported improved understanding of MASLD and its link to diabetes. All participants received T2D medication adjustment (n = 5/10) and/or clinically indicated testing/referral (n = 10/10) for the purpose of improving MASLD.

CONCLUSIONS

We demonstrated that a telehealth intervention designed to proactively deliver EBM of MASLD was feasible and acceptable in a cohort of Latino/a and Black patients with T2D. Opportunities existed to better align each participants' care with guideline-based care of MASLD.

UCF101 Rescues against Diabetes-Evoked Cardiac Remodeling and Contractile Anomalies through AMP-Activated Protein Kinase-Mediated Induction of Mitophagy

INTRODUCTION

Diabetes mellitus is known to provoke devastating anomalies in myocardial structure and function, while effective therapeutic regimen is still lacking. The selective protease inhibitor UCF101 (5-[5-(2-nitrophenyl) furfuryl iodine]-1,3-diphenyl-2-thiobarbituric acid) has been shown to fend off ischemic heart injury, although its impact on diabetic cardiomyopathy remains elusive.

METHODS

Our present work was conducted to examine the effect of UCF101 on experimental diabetes-evoked cardiac geometric and functional abnormalities as well as mechanisms involved. Adult mice were made diabetic using streptozotocin (STZ, 50 mg/kg, i.p., for 5 days) while receiving UCF101 (7.15 mg/kg, i.p.).

RESULTS

STZ evoked cardiac hypertrophy, interstitial fibrosis, mitochondrial ultrastructural damage, oxidative stress, dampened autophagy (LC3B, Beclin 1, elevated p62), mitophagy (FUNDC1 and Parkin with upregulated TOM20), increased left ventricular end systolic diameter, reduced fractional shortening, ejection fraction, cardiomyocyte shortening capacity, velocities of shortening/re-lengthening, and rise in intracellular Ca2+ in conjunction with elongated diastole and intracellular Ca2+ removal, the responses were overtly reconciled by UCF101 with little effects from UCF101 itself. Levels of cell injury markers Omi/HtrA2, TNFα, and stress signaling (JNK, ERK, p38) were overtly enhanced along with compromised phosphorylation of cellular fuel AMP-activated protein kinase (AMPK) (Thr172) and cell survival molecule GSK3β, as well as downregulated SERCA2a and elevated phospholamban, the effect was reversed by UCF101 (except for SERCA2a). AMPK knockout, pharmacological inhibition, the mitophagy inhibitor liensinine, and parkin knockout nullified UCF101-offered cardioprotection in diabetes. UCF101 reversed STZ-induced upregulation in the AMPK degrading enzymes PP2A and PP2C.

CONCLUSION

These findings suggest that UCF101 rescues diabetes-mediated alterations in cardiac structure and function, likely through AMPK-mediated regulation of mitophagy.

Obesity increases the risk of hepatic fibrosis in young adults with type 2 diabetes mellitus: the need to screen

OBJECTIVE

The objective of this study was to determine the prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) in young compared with older adults.

METHODS

Individuals (n = 1420) with (63%) and without type 2 diabetes mellitus (T2D; 37%) who attended internal medicine clinics and did not have a known history of MASLD underwent laboratory evaluation and transient elastography to assess for hepatic steatosis and fibrosis. Magnetic resonance elastography and liver biopsy were recommended when indicated.

RESULTS

A total of 243 participants were ages <45 years, and 1177 were ages ≥45 years. Obesity, T2D, and metabolic syndrome were highly prevalent in young adults. Frequencies of steatosis and fibrosis were high in young adults (50.2% and 7.5% vs. older adults 52.7% and 9.9%, respectively) and were significantly higher in those with both obesity and T2D (71.1% and 15.7%, respectively; p < 0.01). In young adults, T2D and obesity were the strongest risk factors for hepatic fibrosis (odds ratios 4.33 [95% CI: 1.37-13.68] and 1.16 [95% CI: 1.07-1.25], respectively; p < 0.05).

CONCLUSIONS

There is a high prevalence of clinically significant hepatic fibrosis in young adults with cardiometabolic risk factors. Up to one in seven young adults with obesity and T2D had clinically significant hepatic fibrosis on elastography. This highlights the need to screen young adults with cardiometabolic risk factors for MASLD for early detection and intervention.

Detecting altered hepatic lipid oxidation by MRI in an animal model of MASLD

Metabolic dysfunction-associated steatotic liver disease (MASLD) prevalence is increasing annually and affects over a third of US adults. MASLD can progress to metabolic dysfunction-associated steatohepatitis (MASH), characterized by severe hepatocyte injury, inflammation, and eventual advanced fibrosis or cirrhosis. MASH is predicted to become the primary cause of liver transplant by 2030. Although the etiology of MASLD/MASH is incompletely understood, dysregulated fatty acid oxidation is implicated in disease pathogenesis. Here, we develop a method for estimating hepatic β-oxidation from the metabolism of [D15]octanoate to deuterated water and detection with deuterium magnetic resonance methods. Perfused livers from a mouse model of MASLD reveal dysregulated hepatic β-oxidation, findings that corroborate in vivo imaging. The high-fat-diet-induced MASLD mouse studies indicate that decreased β-oxidative efficiency in the fatty liver could serve as an indicator of MASLD progression. Furthermore, our method provides a clinically translatable imaging approach for determining hepatic β-oxidation efficiency.

Advances and counterpoints in type 2 diabetes. What is ready for translation into real-world practice, ahead of the guidelines

This review seeks to address major gaps and delays between our rapidly evolving body of knowledge on type 2 diabetes and its translation into real-world practice. Through updated and improved best practices informed by recent evidence and described herein, we stand to better attain A1c targets, help preserve beta cell integrity and moderate glycemic variability, minimize treatment-emergent hypoglycemia, circumvent prescribing to "treatment failure," and prevent long-term complications. The first topic addressed in this review concerns updates in the 2023 and 2024 diabetes treatment guidelines for which further elaboration can help facilitate integration into routine care. The second concerns advances in diabetes research that have not yet found their way into guidelines, though they are endorsed by strong evidence and are ready for real-world use in appropriate patients. The final theme addresses lingering misconceptions about the underpinnings of type 2 diabetes-fundamental fallacies that continue to be asserted in the textbooks and continuing medical education upon which physicians build their approaches. A corrected and up-to-date understanding of the disease state is essential for practitioners to both conceptually and translationally manage initial onset through late-stage type 2 diabetes.

Bone Fragility in Diabetes and its Management: A Narrative Review

Bone fragility is a serious yet under-recognised complication of diabetes mellitus (DM) that is associated with significant morbidity and mortality. Multiple complex pathophysiological mechanisms mediating bone fragility amongst DM patients have been proposed and identified. Fracture risk in both type 1 diabetes (T1D) and type 2 diabetes (T2D) continues to be understated and underestimated by conventional risk assessment tools, posing an additional challenge to the identification of at-risk patients who may benefit from earlier intervention or preventive strategies. Over the years, an increasing body of evidence has demonstrated the efficacy of osteo-pharmacological agents in managing skeletal fragility in DM. This review seeks to elaborate on the risk of bone fragility in DM, the underlying pathogenesis and skeletal alterations, the approach to fracture risk assessment in DM, management strategies and therapeutic options.

Quantitative Imaging Reveals Steatosis and Fibroinflammation in Multiple Organs in People With Type 2 Diabetes: A Real-World Study

We aimed to determine the extent of multiorgan fat accumulation and fibroinflammation in individuals living with type 2 diabetes. We deeply phenotyped individuals with type 2 diabetes (134 from secondary care, 69 from primary care) with multiorgan, quantitative, multiparametric MRI and compared with 134 matched control individuals without diabetes and 92 control individuals with normal weight. We examined the impact of diabetes duration, obesity status, and glycemic control. Ninety-three of the individuals with type 2 diabetes were reevaluated at 7 months (median). Multiorgan abnormalities were more common in individuals with type 2 diabetes (94%) than in age- and BMI-matched healthy individuals or healthy individuals with normal weight. We demonstrated a high burden of combined steatosis and fibroinflammation within the liver, pancreas, and kidneys (41%, 17%, and 10%) associated with visceral adiposity (73%) and poor vascular health (82%). Obesity was most closely associated with advanced liver disease, renal and visceral steatosis, and multiorgan abnormalities, while poor glycemic control was associated with pancreatic fibroinflammation. Pharmacological therapies with proven cardiorenal protection improved liver and vascular health unlike conventional glucose-lowering treatments, while weight loss or improved glycemic control reduced multiorgan adiposity (P ≤ 0.01). Quantitative imaging in people with type 2 diabetes highlights widespread organ abnormalities and may provide useful risk and treatment stratification.

ARTICLE HIGHLIGHTS

Social Risk and Clinical Outcomes Among Adults With Type 2 Diabetes

Importance

No clear process exists for categorizing social risks in a way that informs effective social risk screening and intervention development.

Objective

To investigate social risk profiles and associations of those profiles with clinical outcomes in adults with diabetes using latent profile analysis.

Design, Setting, and Participants

For this cross-sectional study, a latent profile analysis was conducted using data for adults with type 2 diabetes collected at 2 primary care clinics in the Southeastern US from 2013 to 2014. Data were analyzed from November to December 2023.

Main Outcomes and Measures

Participants completed validated questionnaires for 26 social risk factors within 5 domains of social determinants of health: socioeconomic, neighborhood, education, food, and social and community context. In addition, participants completed questions that assessed psychological risk and behavioral risk. A 3-step latent profile analysis was used to identify different subgroups within the sample. Profiles were then regressed on outcomes of hemoglobin A1c (HbA1c), blood pressure, and quality of life.

Results

A total of 615 participants (mean [SD] age, 61.3 [10.9] years; 379 men [61.6%]) were included. Five latent class profiles were identified. The lowest risk group had significantly higher mental health-related quality of life compared with a group with higher neighborhood risk (β, 1.11; 95% CI, 0.67 to 1.55). The second group had low economic risk but high neighborhood risk and served as the reference group. The third group had high economic and neighborhood risk and had significantly higher blood pressure (β, 8.08; 95% CI, 2.16 to 14.01) compared with the reference. The fourth group had high psychological and behavioral risks but low socioeconomic and neighborhood risks. This group had significantly higher HbA1c (β, 0.47; 95% CI, 0.01 to 0.92) and lower mental health-related quality of life (β, -1.83; 95% CI, -2.41 to -1.24) compared with the reference. The highest risk group indicated high risk in all domains, had significantly higher HbA1c (β, 1.07; 95% CI, 0.50 to 1.63), and had lower mental health-related quality of life (β, -2.15; 95% CI, -2.87 to -1.42) compared with the reference.

Conclusions and Relevance

These findings suggest that social risk profiles can be identified according to social, psychological, and behavioral risk domains and the health outcome of concern among adults with diabetes. Future work should consider the use of social risk profiles in intervention development and testing.

Knowledge and prescribing behaviour of Flemish general practitioners regarding novel glucose-lowering medications: Online cross-sectional survey

AIMS

To determine the knowledge and prescribing behaviour regarding new type 2 diabetes medication in general practice. Physicians in Belgium are bound by the prescription criteria which do not always correspond to the international guidelines.

DESIGN & METHOD

A mixed methods study with an online questionnaire was conducted in Flanders to collect data on demographic characteristics, theoretical knowledge, and prescribing behaviour, using ten theoretical questions and six clinical cases, based on the American Diabetes Association/European Association for the Study of Diabetes (ADA/EASD) guidelines and the Belgian reimbursement criteria.

RESULTS

201 GPs and GPs in training were included in this study with a median age of 30 years and 68 % female participants. On the knowledge questionnaire, the mean test result was 7.15/15 (= 48 %) with a median of 8. Further analysis showed that 90 % of the respondents correctly recommended a sodium-glucose cotransporter 2 (sglt2) inhibitor when the clinical case showed a comorbidity of heart failure, whereas only 42 % suggested correctly a glucagon-like peptide 1 (GLP-1) agonist if presence of cardiovascular disease. Subgroup analysis showed no statistically significant demographic differences in obtained test results. Regarding prescription behaviour, 23 % of the respondents would prescribe medication that did not match the reimbursement criteria in at least one of the 6 proposed clinical cases.

CONCLUSION

This study highlights the need for enhanced knowledge and updated prescribing practices among Flemish GPs and Trainee GPs to effectively manage patients with T2DM.

A rapid action plan to improve diagnosis and management of lipodystrophy syndromes

Introduction

Lipodystrophy syndromes are rare diseases that can present with a broad range of symptoms. Delays in diagnosis are common, which in turn, may predispose to the development of severe metabolic complications and end-organ damage. Many patients with lipodystrophy syndromes are only diagnosed after significant metabolic abnormalities arise. Prompt action by clinical teams may improve disease outcomes in lipodystrophy syndromes. The aim of the Rapid Action Plan is to serve as a set of recommendations from experts that can support clinicians with limited experience in lipodystrophy syndromes.

Methods

The Rapid Action Plan was developed using insights gathered through a series of advisory meetings with clinical experts in lipodystrophy syndromes. A skeleton template was used to facilitate interviews. A consensus document was developed, reviewed, and approved by all experts.

Results

Lipodystrophy is a clinical diagnosis. The Rapid Action Plan discusses tools that can help diagnose lipodystrophy syndromes. The roles of clinical and family history, physical exam, patient and family member photos, routine blood tests, leptin levels, skinfold measurements, imaging studies, and genetic testing are explored. Additional topics such as communicating the diagnosis to the patients/families and patient referrals are covered. A set of recommendations regarding screening and monitoring for metabolic diseases and end-organ abnormalities is presented. Finally, the treatment of lipodystrophy syndromes is reviewed.

Discussion

The Rapid Action Plan may assist clinical teams with the prompt diagnosis and holistic work-up and management of patients with lipodystrophy syndromes, which may improve outcomes for patients with this rare disease.

Diabetes and Hearing Impairment: Knowledge, Attitudes, and Practices Among Providers and Patients

PURPOSE

The purpose of this study was to assess the knowledge, attitudes, and practices among providers and patients regarding hearing impairment and screening referrals in people with diabetes.

METHODS

A cross-sectional survey design among health care providers and patients at an academic medical center in Oklahoma was used to gather knowledge, attitudes, and practices data.

RESULTS

Only 25.6% of providers selected hearing impairment as a complication of diabetes, whereas 96.7% selected retinopathy, kidney dysfunction, and foot infection. Reported barriers to referring patients for hearing impairment screenings were being unfamiliar with recommended screening frequency (57.3%) and existence of higher priorities (35.4%). When asked to select parts of the body affected by diabetes, 21.0% of patients surveyed selected ears, 88.0% selected feet, and 85.0% selected eyes and kidneys. Fewer patients reported being told hearing impairment is a complication of diabetes compared to retinopathy (8.1% vs 85.9%). Additionally, 24.2% of patients reported having a hearing impairment screening, and 96.0% reported having a dilated eye exam.

CONCLUSIONS

Most providers and patients at an academic medical center are unaware of the relationship between diabetes and hearing impairment. Providers reported there are several barriers that need to be overcome to refer patients to audiologists.

Type 2 Diabetes

Type 2 diabetes (T2D) is a prevalent disease that increases risk for vascular, renal, and neurologic complications. Prevention and treatment of T2D and its complications are paramount. Many advancements in T2D care have emerged over the past 5 years, including increased understanding of the importance of early intensive glycemic control, mental health, social determinants of health, healthy eating patterns, continuous glucose monitoring, and the benefits of some drugs for preventing cardiorenal disease. This review summarizes the evidence supporting T2D prevention and treatment, focusing on aspects that are commonly in the purview of primary care physicians.

Patients with autoimmune liver disease have glucose disturbances that mechanistically differ from steatotic liver disease

Autoimmune liver diseases are associated with an increased risk of diabetes, yet the underlying mechanisms remain unknown. In this cross-sectional study, we investigated the glucose-regulatory disturbances in patients with autoimmune hepatitis (AIH, n = 19), primary biliary cholangitis (PBC, n = 15), and primary sclerosing cholangitis (PSC, n = 6). Healthy individuals (n = 24) and patients with metabolic dysfunction-associated steatotic liver disease (MASLD, n = 18) were included as controls. Blood samples were collected during a 120-min oral glucose tolerance test. We measured the concentrations of glucose, C-peptide, insulin, glucagon, and the two incretin hormones, glucose insulinotropic peptide (GIP) and glucagon-like peptide-1 (GLP-1). We calculated the homeostasis model assessment of insulin resistance (HOMA-IR), whole body insulin resistance (Matsuda index), insulin clearance, and insulinogenic index. All patient groups had increased fasting plasma glucose and impaired glucose responses compared with healthy controls. Beta-cell secretion was increased in AIH, PBC, and MASLD but not in PSC. Patients with AIH and MASLD had hyperglucagonemia and hepatic, as well as peripheral, insulin resistance and decreased insulin clearance, resulting in hyperinsulinemia. Patients with autoimmune liver disease had an increased GIP response, and those with AIH or PBC had an increased GLP-1 response. Our data demonstrate that the mechanism underlying glucose disturbances in patients with autoimmune liver disease differs from that underlying MASLD, including compensatory incretin responses in patients with autoimmune liver disease. Our results suggest that glucose disturbances are present at an early stage of the disease.NEW & NOTEWORTHY Patients with autoimmune liver disease but without overt diabetes display glucose disturbances early on in their disease course. We identified pathophysiological traits specific to these patients including altered incretin responses.
