Evolving Global Etiology of Hepatocellular Carcinoma (HCC): Insights and Trends for 2024.

The epidemiology of HCC is changing all over the world and the incidence of HCC is expected to continue increasing over the next 30 years. The changes are in the predisposing factors. Hepatitis B and hepatitis C as predisposing etiologies are decreasing while NAFLD/MAFLD is increasing. The increase in MAFLD is so great that despite the decrease in hepatitis B and C, the overall incidence of HCC is increasing. HCC in persons below the age of 20 years has distinct characteristics different from that of HCC in adults. The changing etiology of hepatocellular carcinoma has implications for the early detection, prevention, the stage of HCC at time of detection and in the treatment of HCC. The extent of these changes and their significance are discussed.

MMP-9 responsive hydrogel promotes diabetic wound healing by suppressing ferroptosis of endothelial cells.

Ferroptosis plays a crucial role in the progression of diabetic wounds, suggesting potential therapeutic strategies to target ferroptosis. Transient receptor potential ankyrin 1 (TRPA1) is a non-selective calcium channel that acts as a receptor for a variety of physical or chemical stimuli. Cinnamaldehyde (CA) is a specific TRPA1 agonist. In in vitro experiments, we observed that high glucose (HG) treatment induced endothelial cell ferroptosis, impairing cell function. CA successfully inhibited endothelial cell ferroptosis, improving migration, proliferation, and tube formation. Further mechanistic studies showed that CA-activated TRPA1-induced Ca2+ influx promoted the phosphorylation of calmodulin-dependent protein kinase II (CaMKII) and nuclear factor-E 2-related factor 2 (Nrf2) translocation, which contributed to the elevation of glutathione peroxidase 4 (GPX4), leading to the inhibition of endothelial cell ferroptosis. In addition, CA was incorporated into an MMP-9-responsive injectable duplex hybrid hydrogel (CA@HA-Gel), allowing its efficient sustained release into diabetic wounds in an inflammation-responsive manner. The results showed that CA@HA-Gel inhibited wound endothelial cell ferroptosis and significantly promoted diabetic wound healing. In summary, the results presented in this study emphasize the potential therapeutic application of CA@HA-Gel in the treatment of diseases associated with ferroptosis.

The association of isocarbophos and isofenphos with different types of glucose metabolism: The role of inflammatory cells.

To investigate the associations between isocarbophos and isofenphos with impaired fasting glucose (IFG) and type 2 diabetes mellitus (T2DM), and to assess the mediation roles of inflammation cells. There were 2701 participants in the case-control study, including 896 patients with T2DM, 900 patients with IFG, 905 subjects with NGT. Plasma isocarbophos and isofenphos concentrations were measured using gas chromatography and triple quadrupole tandem mass spectrometry. Generalized linear models were used to calculate the relationships between plasma isofenphos and isocarbophos levels with inflammatory factor levels and T2DM. Inflammatory cell was used as mediators to estimate the mediating effects on the above associations. Isocarbophos and isofenphos were positively related with T2DM after adjusting for other factors. The odds ratio (95% confidence interval) (OR (95%CI)) for T2DM was 1.041 (1.015, 1.068) and for IFG was 1.066 (1.009, 1.127) per unit rise in ln-isocarbophos. The prevalence of T2DM increased by 6.4% for every 1 unit more of ln-isofenphos (OR (95% CI): 1.064 (1.041, 1.087)). Additionally, a 100% rise in ln-isocarbophos was linked to 3.3% higher ln-HOMA2IR and a 0.029 mmol/L higher glycosylated hemoglobin (HbA1c) (95% CI: 0.007, 0.051). While a 100% rise in ln-isofenphos was linked to increase in ln-HOMA2 and ln-HOMA2IR of 5.8% and 3.4%, respectively. Furthermore, white blood cell (WBC) and neutrophilic (NE) were found to be mediators in the relationship between isocarbophos and T2DM, and the corresponding proportions were 17.12% and 17.67%, respectively. Isofenphos and isocarbophos are associated with IFG and T2DM in the rural Chinese population, WBC and NE have a significant role in this relationship.

Trends in endogenous insulin secretion capacity and anti-islet autoantibody titers in two childhood-onset slowly progressive insulin-dependent diabetes mellitus cases.

Slowly progressive insulin-dependent (type 1) diabetes mellitus (SPIDDM) is a subtype of type 1 diabetes. Although SPIDDM is not rare among Japanese children, there are few reports on endogenous insulin secretory capacity and anti-pancreatic islet autoantibodies in pediatric SPIDDM. We followed the trends in endogenous insulin secretory capacity and anti-pancreatic islet autoantibody titers in two pediatric SPIDDM cases over several years. Case 1 developed insulin deficiency eight months after diabetes diagnosis; as her insulinoma-associated antibody test result was positive, insulin therapy was initiated. Fourteen months after the diagnosis, she tested positive for glutamic acid decarboxylase autoantibodies (GADA) and was diagnosed with SPIDDM. Case 2 was mildly positive for GADA at the onset of diabetes, but became a high titer during the course of the disease. Fourteen months after the diagnosis of diabetes, he became mildly insulin deficient, and insulin therapy was initiated. However, his insulin secretory capacity was preserved for 60 mo after the onset. SPIDDM is generally indistinguishable from type 2 diabetes at diagnosis; therefore, repeated evaluation of the insulin secretory capacity and anti-islet autoantibodies facilitates early diagnosis and appropriate treatment, especially in nonobese children with type 2 diabetes.

Chinese expert consensus on blood lipid management in patients with diabetes (2024 edition).

Diabetes is a significant independent risk factor for atherosclerotic cardiovascular disease (ASCVD), with dyslipidemia playing a critical role in the initiation and progression of ASCVD in diabetic patients. In China, the current prevalence of dyslipidemia in diabetes is high, but the control rate remains low. Therefore, to enhance lipid management in patients with diabetes, the Endocrinology and Metabolism Physician Branch of the Chinese Medical Doctor Association, in collaboration with the Experts' Committee of the National Society of Cardiometabolic Medicine, has convened experts to develop a consensus on the management of dyslipidemia in patients with type 1 or type 2 diabetes. The development of this consensus is informed by existing practices in lipid management among Chinese diabetic patients, incorporating contemporary evidence-based findings and guidelines from national and international sources. The consensus encompasses lipid profile characteristics, the current epidemiological status of dyslipidemia, ASCVD risk stratification, and lipid management procedures in diabetic patients. For the first time, both low-density lipoprotein cholesterol and non-high-density lipoprotein cholesterol have been recommended as primary targets for lipid intervention in diabetic patients. The consensus also includes a summary and recommendations for lipid management strategies in special diabetic populations, including children and adolescents, individuals aged 75 years and older, patients with chronic kidney disease, metabolic-associated fatty liver disease, and those who are pregnant. This comprehensive consensus aims to improve cardiovascular outcomes in diabetic patients by contributing to the dissemination of key clinical advancements and guiding clinical practice.

Effects of Comorbid Depressive Symptoms and Diabetes Mellitus on Functional Dyspepsia in Older Patients.

Objective: Diabetes mellitus (DM) is a global epidemic; comorbid depressive symptoms are highly prevalent worldwide and commonly manifests as physical symptoms, including functional dyspepsia (FD), a gastrointestinal psychosomatic disorder. This study aimed to explore the effects of comorbid depressive symptoms and DM on FD in older patients. Methods: In total, 420 older patients with DM completed measures of depression, anxiety, and FD. Relevant demographic characteristics and medical information were self-reported and obtained from the hospital information system. Results: Among older patients with DM, 30.48% had depressive symptoms. Patients with depressive symptoms were more likely to have FD than those without (42.19% vs. 20.21%, P = .000). Dyspepsia symptoms were more frequent in patients with depression (P = .022). The greater the amount of dyspepsia symptoms, the higher the depression symptoms score (P = .000). Furthermore, dyspepsia symptoms were positively correlated with depressive symptoms (r values were 0.292, 0.311, 0.297, 0.369; all had P < .05). Both FD subtypes, postprandial distress, and epigastric pain syndromes affected depressive symptoms (P < .05). Smoking was significantly associated with FD (P < .05). Diabetes mellitus complications, such as diabetic neuropathy, different therapeutic methods, and anxiety symptoms, influenced FD overlap (x 2 values were 6.298, 16.314, and 30.744; P < .05). Anxiety (odds ratio = 1.832, 95% Confidence Intervals (CI) 1.185-2.834) was a risk factor for FD in comorbid depressive symptoms and diabetes (P < .05). Conclusion: Comorbid depressive symptoms and DM overlapped with physical symptoms, such as FD, in older patients with DM. Lifestyle, diabetic factors, and anxiety were the associated risk factors.

Linking the reversal of gestational insulin resistance to postpartum depression.

BACKGROUND: Postpartum depression (PPD) constitutes a significant mental health disorder affecting almost one fifth of pregnancies globally. Despite extensive research, the precise etiological mechanisms underlying PPD remain elusive. However, several risk factors like genetic predisposition, hormonal fluctuations, and stress-related environmental and psychosocial triggers have been found to be implicated in its development. MAIN: Recently, an increased risk of PPD has been reported to be associated with gestational diabetes mellitus (GDM), which is characterized by the disruption of glucose metabolism, primarily attributed to the emergence of insulin resistance (IR). While IR during pregnancy seems to be an evolutionary adaptative mechanism to handle the profound metabolic alterations during pregnancy, its subsequent resolution following delivery necessitates a reconfiguration of the metabolic landscape in both peripheral tissues and the central nervous system (CNS). Considering the pivotal roles of energy metabolism, particularly glucose metabolism, in CNS functions, we propose a novel model that such pronounced changes in IR and the associated glucose metabolism seen postpartum might account for PPD development. This concept is based on the profound influences from insulin and glucose metabolism on brain functions, potentially via modulating neurotransmitter actions of dopamine and serotonin. Their sudden postpartum disruption is likely to be linked to mood changes, as observed in PPD. CONCLUSIONS: The detailed pathogenesis of PPD might be multifactorial and still remains to be fully elucidated. Nevertheless, our hypothesis might account in part for an additional etiological factor to PPD development. If our concept is validated, it can provide guidance for future PPD prevention, diagnosis, and intervention.

The effect of hydrophilic statins on adiponectin, leptin, visfatin, and vaspin levels in streptozocin-induced diabetic rats.

Statins may affect glucose metabolism through adipokines. The aim of this study was to measure the effects of hydrophilic statins on the levels of several adipokines in diabetic rats. Wistar albino rats were divided into four groups: healthy control, untreated diabetic, diabetic treated with pravastatin, and diabetic treated with rosuvastatin. Diabetes was induced by intraperitoneal injection of STZ. Thereafter, 20 mg/kg/day doses of either pravastatin or rosuvastatin were administered to the treated diabetic rats for 8 weeks. At the end of the experiment, the body weights, fasting blood glucose levels, serum insulin levels, and insulin resistance, as well as the serum adiponectin, leptin, visfatin, and vaspin levels, were measured. Fasting blood glucose and insulin resistance levels were significantly higher, whereas insulin levels and body weight were significantly lower in the untreated diabetic group than in the control group. Diabetes caused significant decreases in adiponectin, leptin, and vaspin levels but a significant increase in visfatin levels. Pravastatin treatment significantly increased body weight and decreased fasting blood glucose levels, whereas rosuvastatin decreased body weight but did not affect fasting blood glucose levels. Pravastatin caused significant increases in both adiponectin and vaspin levels. However, rosuvastatin did not affect the adiponectin level but caused a significant decrease in the vaspin levels. Both pravastatin and rosuvastatin treatments decreased the leptin and visfatin levels. In conclusion, pravastatin is more effective at improving fasting blood glucose levels and body weight in diabetic rats, probably by increasing adiponectin and vaspin levels.

Serum biochemical evaluation following administration of imidazolyl thiazolidinedione in streptozotocin-induced diabetic rats.

BACKGROUND: Diabetes mellitus represents a prominent global health concern, characterized by a rising prevalence rate. Type 2 Diabetes Mellitus (T2DM) is purported to be associated with an intricate interplay of genetic, environmental, and lifestyle factors. While some progress have been made in T2DM management, controlling associated complications remains a great challenge in medicine. OBJECTIVES: This study investigated a synthesized Imidazolyl Thiazolidinedione antidiabetic agent (PA9), focusing on serum parameters. METHODS: Streptozotocin-induced diabetic rats (n = 6) were subjected to orally treatment with PA9 (synthesized by Shakour et al. in an equal dose of a standard drug, 0.011 mmol/kg). The study conducted to measure some specific serum factors, including lipid profiles, liver and kidney enzymes, cardiac enzymes, and oxidative stress markers, both before and after treatment. RESULTS: The study findings indicated that PA9 effectively ameliorates hyperlipidemia by significantly reducing total cholesterol and triglyceride levels in serum. Additionally, PA9 demonstrated hepatoprotective effects against TZD-induced injuries, as evidenced by decreased levels of alanine transaminase and, alkaline phosphatase. In addition, PA9 also exhibited a modulatory effect on a cardiac injury marker, creatine kinase MB. Moreover, PA9 demonstrated antioxidant properties by reducing oxidative stress markers and enhancing the activities of catalase, thiol, and superoxide dismutase. CONCLUSIONS: The synthesized TZD compound (PA9) stands out as a highly promising agent for the management of diabetes. Its significant antihyperlipidemic effects, preventive influences on organ injuries, and demonstrated efficacy in reducing oxidative stress marker (SOD) make it therapeutic agent in diabetes management. This study lays the groundwork for innovative strategies in diabetes management.

Modified streptozotocin-induced diabetic model in rodents.

Streptozotocin (STZ)-induced type I diabetes mellitus (DM) models have been pivotal in diabetes research due to their ability to mimic the insulin-dependent hyperglycemia akin to human type I diabetes. However, these models often suffer from poor induction rates and low survival post-STZ induction, especially in long-term experiments, necessitating insulin supplementation, which introduces additional variables to experiments. To address this, we present a novel modification to the STZ-induced DM model in C57BL/6J mice to improve survival rates without insulin supplementation. Our method involves non-fasting, low-dose STZ injections dissolved in pH-neutral phosphate buffer saline instead of acidic sodium citrate buffer, administered over 5 days. We observed hyperglycemia induction in 94.28% of mice within a week post-injection, with stable high blood glucose levels, stable body weight, and minimal mortality up to 21 weeks. Notably, omitting 10% sucrose in water and fasting did not affect hyperglycemia induction. Our findings suggest that the modified protocol not only decreases the experimental effort of the researchers, but reduces animal stress and mortality, thus enhancing experimental outcomes and animal welfare. By optimizing the STZ-induced DM model in C57BL/6J mice, our study provides a valuable resource for researchers aiming to study diabetes and its complications while minimizing experimental variability and animal usage.

Microcirculatory Dysfunction in Patients With Diabetes Mellitus Detected by a Distributed System of Wearable Laser Doppler Flowmetry Analysers.

The paper is devoted to the study of perfusion and amplitude-frequency spectra of laser Doppler flowmetry (LDF) signals in patients with diabetes mellitus (DM) in different skin areas of the upper and lower extremities using a distributed system of wearable LDF analysers. LDF measurements were performed in the areas of the fingers, toes, wrists and shins. The mean perfusion values, the amplitudes of blood flow oscillations in endothelial, neurogenic, myogenic, respiratory and cardiac frequency ranges, and the values of nutritive blood flow were analysed. The results revealed a decrease in tissue perfusion and nutritive blood flow in the lower extremities and an increase in these parameters in the upper extremities in patients with DM. A decrease in the amplitudes of endothelial and neurogenic oscillations was observed. The obtained results confirm the possibility of using wearable LDF analysers to detect differences in the blood flow regulation in normal and pathological conditions.

Patients with diabetes struggling to afford food and control their HbA1c in food-insecure areas in Bronx, NY.

OBJECTIVE: To characterise the association between risk of poor glycaemic control and self-reported and area-level food insecurity among adult patients with type 2 diabetes. DESIGN: We performed a retrospective, observational analysis of cross-sectional data routinely collected within a health system. Logistic regressions estimated the association between glycaemic control and the dual effect of self-reported and area-level measures of food insecurity. SETTING: The health system included a network of ambulatory primary and speciality care sites and hospitals in Bronx County, NY. PARTICIPANTS: Patients diagnosed with type 2 diabetes who completed a health-related social need (HRSN) assessment between April 2018 and December 2019. RESULTS: 5500 patients with type 2 diabetes were assessed for HRSN with 7·1 % reporting an unmet food need. Patients with self-reported food needs demonstrated higher odds of having poor glycaemic control compared with those without food needs (adjusted OR (aOR): 1·59, 95 % CI: 1·26, 2·00). However, there was no conclusive evidence that area-level food insecurity alone was a significant predictor of glycaemic control (aOR: 1·15, 95 % CI: 0·96, 1·39). Patients with self-reported food needs residing in food-secure (aOR: 1·83, 95 % CI: 1·22, 2·74) and food-insecure (aOR: 1·72, 95 % CI: 1·25, 2·37) areas showed higher odds of poor glycaemic control than those without self-reported food needs residing in food-secure areas. CONCLUSIONS: These findings highlight the importance of utilising patient- and area-level social needs data to identify individuals for targeted interventions with increased risk of adverse health outcomes.

Changes in the incidence of type 2 diabetes in Australia, 2005-2019, overall and by socio-demographic characteristics: a population-based study.

OBJECTIVES: To estimate changes in the incidence of clinically diagnosed type 2 diabetes in Australia, overall and by age, sex, socio-economic disadvantage, geographic remoteness, and country of birth. STUDY DESIGN: Population-based study; analysis of National Diabetes Services Scheme (NDSS) data (age-period-cohort models). SETTING, PARTICIPANTS: Data were extracted for incident cases of type 2 diabetes, 1 January 2005 to 31 December 2019, in residents of the Australian Capital Territory, New South Wales, Queensland, and Victoria aged 20 years or older registered with the NDSS. The numbers of people at risk were obtained from the Australian Bureau of Statistics. MAIN OUTCOME MEASURES: Changes in the incidence of type 2 diabetes, 2005-2019, by age, postcode-level socio-economic disadvantage (Index of Relative Socioeconomic Disadvantage) and remoteness (major city, inner regional, outer regional/remote/very remote), and country of birth, stratified by sex. RESULTS: During 2005-2019, 741 535 people aged 20 years or older with incident type 2 diabetes were registered with the NDSS; 421 190 were men (56.8%). Overall, the incidence of type 2 diabetes increased with age (until about age 70 years) and socio-economic disadvantage for both sexes; it was higher in inner regional areas than in major cities or outer regional/remote/very remote areas during 2005-2015, but highest among people in major cities after 2015. The age-standardised incidence of type 2 diabetes increased during 2005-2010, both among men (annual percentage change [APC], 4.4%; 95% confidence interval [CI], 3.6-5.2%) and women (APC, 2.9%; 95% CI, 2.2-3.7%); it declined during 2010-2019 among both men (APC, -5.2%; 95% CI, -5.4% to -4.9%) and women (APC, -6.5%; 95% CI, -6.8% to -6.2%). In general, similar patterns (but of differing magnitude) applied to all age, sex, socio-economic disadvantage, and remoteness groups. However, the incidence of type 2 diabetes increased during 2011-2019 among people born in Asia, North Africa and the Middle East, and the Pacific Islands. CONCLUSIONS: The incidence of type 2 diabetes in Australian adults declined during 2010-2019 across all age, sex, socio-economic disadvantage, and remoteness groups, but increased among people from Asia, North Africa and the Middle East, and the Pacific Islands.

Optimal tacrolimus levels for reducing CKD risk and the impact of intrapatient variability on CKD and ESRD development following liver transplantation.

Background/Aims: This study aimed to identify the risk factors for chronic kidney disease (CKD) and end-stage renal disease (ESRD) following liver transplantation (LT), with a specific focus on tacrolimus levels and intrapatient variability (IPV). Methods: Among the 1,076 patients who underwent LT between 2000 and 2018, 952 were included in the analysis. The tacrolimus doses and levels were recorded every 3 months, and the IPV was calculated using the coefficient of variability. The cumulative incidence rates of CKD and ESRD were calculated based on baseline kidney function at the time of LT. The impact of tacrolimus levels and their IPV on the development of CKD and ESRD was evaluated, and the significant risk factors were identified. Results: Within a median follow-up of 97.3 months, the 5-year cumulative incidence rates of CKD (0.58 vs. 0.24) and ESRD (0.07 vs. 0.01) were significantly higher in the acute kidney injury (AKI) group than in the normal glomerular filtration rate (GFR) group. In the normal GFR group, the tacrolimus levels were identified as a risk factor for CKD, with a level of ≤4.5 ng/mL suggested as optimal for minimizing the risk of CKD. Furthermore, the IPV of tacrolimus levels and doses emerged as a significant risk factor for CKD development in both groups (P<0.05), with tenofovir disoproxil fumarate also being a risk factor in HBV-infected patients. The IPV of tacrolimus levels was also a significant factor in ESRD development (P<0.05). Conclusions: This study elucidated the optimal tacrolimus through level and highlighted the impact of IPV on the CKD and ESRD development post-LT.

[The Expression of TP53TG1, LINC00342, MALAT1, H19, and MEG3 Long Noncoding RNAs in Type 2 diabetes mellitus].

Type 2 diabetes is a complex and multifactorial metabolic disorder. The frequency of type 2 diabetes has dramatically increased worldwide. Long noncoding RNAs play a regulatory role in pathological processes of type 2 diabetes. The aim of the study was to analyze TP53TG1, LINC00342, MALAT1, H19, and MEG3 lncRNAs in patients with type 2 diabetes and metabolic parameters, as well as the risk of diabetic retinopathy. Participants included 51 patients with diabetes and 70 healthy individuals. The expression of the TP53TG1 and LINC00342 genes was significantly decreased in the patients with diabetes compared to healthy individuals. MALAT1 gene expression was higher in diabetes patients. H19 gene expression was increased in the patients with diabetic retinopathy compared patients without retinopathy. TP53TG1, LINC00342, and MEG3 expression was decreased in patients with diabetic retinopathy and MALAT1 expression was increased. H19 is positively correlated with triglyceride levels; TP53TG1 and LINC00342 are positively correlated with HbA1c levels and fasting glucose levels. MALAT1 is negatively correlated with HDL levels and positively correlated with LDL levels. A decrease in the expression level of TP53TG1 and LINC00342 and an increase in the level of MALAT1 in diabetes, as well as an association with glycemic control, indicate the role of the studied noncoding RNAs in the development of type 2 diabetes mellitus and retinopathy and can be considered as candidates for early diagnosis of type 2 diabetes.

Management of acute kidney disease in type 2 diabetes: the potential role of GLP-1 RAs and SGLT2-Is.

Acute kidney disease (AKD) is defined as subacute damage and/or loss of kidney function occurring 7 to 90 days after acute kidney injury (AKI), and bearing a high risk of progression to chronic kidney disease. Current management of AKD is non-specific and includes prevention of repeated AKI, early and regular follow-up by a nephrologist, resumption and dose adjustment of statins and renin-angiotensin system inhibitors, optimization of blood pressure control, nutrition management, and nephrotoxin avoidance. Recently, SGLT2i and GLP1- RAs have emerged as potential therapeutic tools preventing the transition from acute to chronic kidney disease due to their efficacy in preserving renal function.

Bioengineered Nanomedicines Targeting the Intestinal Fc Receptor Achieve the Improved Glucoregulatory Effect of Semaglutide in a Type 2 Diabetic Mice Model.

The oral administration of the glucagon-like peptide-1 analogue, semaglutide, remains a hurdle due to its limited bioavailability. Herein, neonatal Fc receptor (FcRn)-targeted nanoparticles (NPs) were designed to enhance the oral delivery of semaglutide. The nanocarriers were covalently linked to the FcRn-binding peptide FcBP or the affibody molecule ZFcRn that specifically binds to the human FcRn (hFcRn) in a pH-dependent manner. These FcRn-targeted ligands were selected over the endogenous ligands of the receptor (albumin and IgG) due to their smaller size and simpler structure, which could facilitate the transport of functionalized NPs through the tissues. The capacity of FcRn-targeted semaglutide-NPs in controlling the blood glucose levels was evaluated in an hFcRn transgenic mice model, where type 2 diabetes mellitus (T2DM) was induced via intraperitoneal injection of nicotinamide followed by streptozotocin. The encapsulation of semaglutide into FcRn-targeted NPs was translated in an improved glucoregulatory effect in T2DM-induced mice when compared to the oral free semaglutide or nontargeted NP groups, after daily oral administrations for 7 days. Notably, a similar glucose-lowering response was observed between both FcRn-targeted NPs and the subcutaneous semaglutide groups. An increase in insulin pancreatic content and a recovery in ß cell mass were visualized in the mice treated with FcRn-targeted semaglutide-NPs. The biodistribution of fluorescently labeled NPs through the gastrointestinal tract demonstrated that the nanosystems targeting the hFcRn are retained longer in the ileum and colorectum, where the expression of FcRn is more prevalent, than nontargeted NPs. Therefore, FcRn-targeted nanocarriers proved to be an effective platform for improving the pharmacological effect of semaglutide in a T2DM-induced mice model.

Effect of Gestational Diabetes Mellitus on Newborn Hearing: A Systematic Review.

OBJECTIVE: Gestational diabetes mellitus (GDM) is associated with several adverse health conditions in newborns such as preterm birth, hyperbilirubinemia, macrosomia, respiratory distress. However, the effect of GDM on the hearing sensitivity of newborns is still unclear. The study aimed to explore the effect of GDM on newborn hearing. The study aimed to explore the effect of GDM on newborn hearing. METHOD: A systematic search was conducted using PubMed, Scopus, and CHINAL databases. Keywords like "gestational diabetes," "diabetic pregnancies," "hearing loss," "hearing impairment," and "hearing disorder" were used to form a search string. The Rayyan software was used for screening procedure. The full-length articles were shortlisted, extracted, and appraised. RESULTS: The 7 articles were included in the review. Findings suggest that hearing loss is more prevalent in newborns with GDM pregnancies than in non-GDM pregnancies. In addition, OAE findings were "referred during the first hearing screening of newborns with GDM pregnancies." The refer rate of the first bilateral hearing screening was higher for newborns with GDM pregnancies. Furthermore, children of diabetic pregnancies were found to be at risk of bilateral hearing loss, particularly sensorineural in nature. CONCLUSION: The present systematic review suggests an association between GDM and a higher refer rate in hearing screening. A multidisciplinary collaboration between gynecologists, pediatricians, and audiologists can smoothen the early detection of hearing loss in newborns with GDM pregnancies, leading to early intervention and better clinical outcomes to improve the quality of life of affected newborns.

Development and Validation of a Nocturnal Hypoglycaemia Risk Model for Patients With Type 2 Diabetes Mellitus.

AIM: To develop and test different machine learning algorithms for predicting nocturnal hypoglycaemia in patients with type 2 diabetes mellitus. DESIGN: A retrospective study. METHODS: We collected data from dynamic blood glucose monitoring of patients with T2DM admitted to the Department of Endocrinology and Metabolism at a hospital in Shanghai, China, from November 2020 to January 2022. Patients undergone the continuous glucose monitoring (CGM) for ≥ 24 h were included in this study. Logistic regression, random forest and light gradient boosting machine algorithms were employed, and the models were validated and compared using AUC, accuracy, specificity, recall rate, precision, F1 score and the Kolmogorov-Smirnov test. RESULTS: A total of 4015 continuous glucose-monitoring data points from 440 patients were included, and 28 variables were selected to build the risk prediction model. The 440 patients had an average age of 62.7 years. Approximately 48.2% of the patients were female and 51.8% were male. Nocturnal hypoglycaemia appeared in 573 (14.30%) of 4015 continuous glucose monitoring data. The light gradient boosting machine model demonstrated the highest predictive performances: AUC (0.869), specificity (0.802), accuracy (0.801), precision (0.409), recall rate (0.797), F1 score (0.255) and Kolmogorov (0.603). The selected predictive factors included time below the target glucose range, duration of diabetes, insulin use before bed and dynamic blood glucose monitoring parameters from the previous day. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

Altered Subcortical Brain Volume and Cortical Thickness Related to Insulin Resistance in Type 2 Diabetes Mellitus.

PURPOSE: The objective of this study is to examine the alterations in subcortical brain volume and cortical thickness among individuals diagnosed with Type 2 diabetes mellitus (T2DM) through the application of morphometry techniques and, additionally, to investigate the potential association between these modifications and insulin resistance (IR). MATERIALS AND METHODS: The present cross-sectional study comprised a total of 121 participants (n = 48 with healthy controls [HCs] and n = 73 with T2DM) who were recruited and underwent a battery of cognitive testing and structural magnetic resonance imaging (MRI). FreeSurfer was used to process the MRI data. Analysis of covariance compared discrepancies in cortical thickness and subcortical brain volume between T2DM and HCs, adjusting for the potential confounding effects of gender, age, education, and body mass index (BMI). Exploratory partial correlations investigated links between IR and brain structure in T2DM participants. RESULTS: Compared with HCs, individuals with T2DM demonstrated a cortical thickness decrease in the right caudal middle frontal gyrus, right pars opercularis, left precentral gyrus, and bilateral superior frontal gyrus. Furthermore, this study for T2DM found that the severity of IR was inversely related to the volume of the left putamen and left hippocampus, as well as the thickness of the left pars orbitalis, left pericalcarine, right entorhinal area, and right rostral anterior cingulate gyrus. CONCLUSION: The evidence for structural brain changes in T2DM was observed, and alterations in cortical thickness were concentrated in the frontal lobes. Correlations between IR and frontal cortical thinning may serve as a potential neuroimaging marker of T2DM and lead to various diabetes-related brain complications.
