Background: Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients. Methods: Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines. Results: Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher. Conclusion MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.

Objective To construct a predictive model for cerebral small vessel disease (CSVD) MRI burden based on β2-microglobulin (β2-MG) and lipoprotein(a) [Lp(a)], analyze its predictive value, and validate the model. Methods A total of 138 CSVD patients admitted to Anhui No.2 Provincial People’s Hospital from February 2023 to August 2024 were enrolled. Patients were divided into a low-burden group (n=63) and a moderate/severe burden group (n=75) according to the CSVD MRI burden scoring criteria. The related clinical data were compared between the two groups. Binary logistic regression analysis was used to identify independent factors for CSVD moderate/severe MRI burden. A nomogram predictive model was constructed based on these factors and its performance was evaluated. Results The proportions of male patients, as well as those with a history of diabetes or hypertension, were significantly higher in the moderate/severe burden group than those in the low burden group. Additionally, the age of patients in the moderate/severe burden group was significantly older, and the levels of β2-MG, Lp(a), and homocysteine (Hcy) were higher than those in the low burden group (P＜0.01). Binary logistic regression analysis revealed that hypertension, diabetes, β2-MG, and Lp(a) were independent factors for CSVD moderate/severe MRI burden (P＜0.05). The nomogram predictive model based on these four factors had a cut-off value of 0.467 0, with an area under curve (AUC) of 0.838 7 (95%CI 0.760 8-0.916 6) in the training set (n＝97) and 0.854 1 (95%CI 0.742 1-0.966 1) in the internal validation set (n＝41) . The calibration curve demonstrated good agreement between predicted and observed values. Decision curve analysis (DCA) indicated that the nomogram model had good clinical utility. Conclusions The nomogram model based on β2-MG and Lp(a) has high predictive performance in assessing the risk of CSVD moderate/severe MRI burden, with good discrimination and calibration.

Objective:To determine the incidence of adrenal incidentalomas(AIs) in patients with diabetes mellitus and the metabolism profiles.Methods:A total of 615 hospitalized patients with diabetes mellitus in the Department of Endocrinology and Metabolism of Peking University People′s Hospital from March 2020 to May 2021 were retrospectively included in this study. AIs were screened by unenhanced chest computed tomography(CT) retrospectively and subsequently confirmed by multiplanar reconstruction. Participants′ physical indicators, metabolic profiles, and adrenal function parameters were collected. Unpaired t test, Mann-Whitney U test, and Chi-Square test were adopted to compare the metabolism profiles between diabetes mellitus patients with or without AIs. Regression models were used to estimate the correlations between AIs and the metabolism profiles such as blood glucose, blood lipids, blood pressure, and the adrenal function parameters.Results:Twenty-seven out of 615 participants were detected with AIs(4.4%). Patients with AIs had higher body mass index, waist circumference, and hip circumference than patients without AIs [(29.4±5.1)kg/m 2vs(26.8±3.8)kg/m 2,P=0.018; (102.3±11.7)cm vs(95.8±10.3)cm, P=0.002; (107.3±10.1)cm vs(101.4±7.6)cm, P=0.008]. The levels of serum uric acid and urinary albumin/creatinine ratio were also significantly increased in patients with AIs [(409.6±118.1)μmol/L vs(357.4±100.6)μmol/L, P=0.009; 21.25(7.49, 180.24)mg/g vs 8.60(4.71, 34.56)mg/g, P=0.010]. Besides, individuals with AIs were also associated with a higher risk of co-existing hypertension( P=0.045). Conclusion:The incidence of AIs in patients with diabetes is 4.4%. The presence of AIs in patients with diabetes may associated with increased risk of obesity and hypertension.

Objective:To explore the effect of comfort nursing intervention in hospice care for advanced cancer patients at home, and to provide reference for hospice care for advanced cancer patients at home.Methods:A randomized controlled trial was conducted. A total of 105 patients with advanced cancer who were treated in the Cancer Hospital Affiliated to Harbin Medical University from January to February 2023 were selected as the research objects. According to the random number table, they were divided into control group of 53 cases and intervention group of 52 cases. The control group received routine nursing methods, while the intervention group received comfort nursing interventions on this basis. The intervention lasted for 4 weeks. The changes in palliative care outcomes, quality of life and death anxiety were compared between the two groups before and after intervention.Results:Totally 105 cases were included, 53 cases in the control group and 52 cases in the intervention group. In the control group, there were 25 males, 28 females, aged (58.96 ± 10.71) years old; in the intervention group, there were 22 males, 30 females, aged (59.82 ± 10.53) years old. Before intervention, there was no statistically significant difference in palliative care outcomes, quality of life and cancer death anxiety scores between the two groups of patients (all P>0.05). After intervention, the total score of palliative care outcomes in the intervention group was (13.34 ± 5.88) points, significantly lower than (16.15 ± 5.72) points in the control group, with a statistically significant difference ( t = 2.48, P<0.05). The overall health status score of quality of life was (68.55 ± 9.34) points in the intervention group, higher than (63.01 ± 9.28) points in the control group ( t = 3.05, P<0.05). The total score of cancer death anxiety was (8.85 ± 2.72) points, significantly lower than (10.59 ± 3.14) points of the control group, with a statistically significant difference ( t = 3.04, P<0.05). Conclusions:The application of comfort nursing mode in home based hospice care can improve the quality of hospice care for advanced cancer patients, reduce their level of death anxiety, and is of great significance for improving the quality of life of advanced cancer patients.
