The impact of age and number of mutations on the size of clonal hematopoiesis.

Clonal hematopoiesis (CH) represents the clonal expansion of hematopoietic stem cells and their progeny driven by somatic mutations. Accurate risk assessment of CH is critical for disease prevention and clinical decision-making. The size of CH has been showed to associate with higher disease risk, yet, factors influencing the size of CH are unknown. In addition, the characteristics of CH in long-lived individuals are not well documented. Here, we report an in-depth analysis of CH in longevous (≥90 y old) and common (60~89 y old) elderly groups. Utilizing targeted deep sequencing, we found that the development of CH is closely related to age and the expression of aging biomarkers. The longevous elderly group exhibited a significantly higher incidence of CH and significantly higher frequency of TET2 and ASXL1 mutations, suggesting that certain CH could be beneficial to prolong life. Intriguingly, the size of CH neither correlates significantly to age, in the range of 60 to 110 y old, nor to the expression of aging biomarkers. Instead, we identified a strong correlation between large CH size and the number of mutations per individual. These findings provide a risk assessment biomarker for CH and also suggest that the evolution of the CH is influenced by factor(s) in addition to age.

Integrated metabolome and transcriptome analyses reveal the role of BoGSTF12 in anthocyanin accumulation in Chinese kale (Brassica oleracea var. alboglabra).

BACKGROUND: The vivid red, purple, and blue hues that are observed in a variety of plant fruits, flowers, and leaves are produced by anthocyanins, which are naturally occurring pigments produced by a series of biochemical processes occurring inside the plant cells. The purple-stalked Chinese kale, a popular vegetable that contains anthocyanins, has many health benefits but needs to be investigated further to identify the genes involved in the anthocyanin biosynthesis and translocation in this vegetable. RESULTS: In this study, the purple- and green-stalked Chinese kale were examined using integrative transcriptome and metabolome analyses. The content of anthocyanins such as cyanidin-3-O-(6″-O-feruloyl) sophoroside-5-O-glucoside, cyanidin-3,5-O-diglucoside (cyanin), and cyanidin-3-O-(6″-O-p-hydroxybenzoyl) sophoroside-5-O-glucoside were considerably higher in purple-stalked Chinese kale than in its green-stalked relative. RNA-seq analysis indicated that 23 important anthocyanin biosynthesis genes, including 3 PAL, 2 C4H, 3 4CL, 3 CHS, 1 CHI, 1 F3H, 2 FLS, 2 F3'H, 1 DFR, 3 ANS, and 2 UFGT, along with the transcription factor BoMYB114, were significantly differentially expressed between the purple- and green-stalked varieties. Results of analyzing the expression levels of 11 genes involved in anthocyanin production using qRT-PCR further supported our findings. Association analysis between genes and metabolites revealed a strong correlation between BoGSTF12 and anthocyanin. We overexpressed BoGSTF12 in Arabidopsis thaliana tt19, an anthocyanin transport mutant, and this rescued the anthocyanin-loss phenotype in the stem and rosette leaves, indicating BoGSTF12 encodes an anthocyanin transporter that affects the accumulation of anthocyanins. CONCLUSION: This work represents a key step forward in our understanding of the molecular processes underlying anthocyanin production in Chinese kale. Our comprehensive metabolomic and transcriptome analyses provide important insights into the regulatory system that controls anthocyanin production and transport, while providing a foundation for further research to elucidate the physiological importance of the metabolites found in this nutritionally significant vegetable.

Transcription factor 21 rs12190287 polymorphism is related to stable angina and ST elevation myocardial infarction in a Chinese Population.

Background: Transcription factor 21 (TCF21, epicardin, capsuling, pod-1) is expressed in the epicardium and is involved in the regulation of cell fate and differentiation via epithelial-mesenchymal transformation during development of the heart. In addition, TCF21 can suppress the differentiation of epicardial cells into vascular smooth muscle cells and promote cardiac fibroblast development. This study aimed to explore whether TCF21 gene (12190287G/C) variants affect coronary artery disease risk. Methods: We enrolled 381 patients who had stable angina, 138 with ST elevation myocardial infarction (STEMI), and 276 healthy subjects. Genotyping of rs12190287 of the TCF21 gene was performed. Results: Higher frequencies of the CC genotype were found in the patients with stable angina/STEMI than in the healthy controls. After adjusting for diabetes mellitus, hypertension, age, sex, smoking, body mass index and hyperlipidemia, the patients with the CC genotype of the TCF21 gene were associated with 2.49- and 9.19-fold increased risks of stable angina and STEMI, respectively, compared to the patients with the GG genotype. Furthermore, TCF21 CC genotypes showed positive correlations with both stable angina and STEMI, whereas TCF21 GG genotypes exhibited a negative correlation with STEMI. Moreover, the stable angina and STEMI patients with the CC genotype had significantly elevated high-sensitivity C-reactive protein levels than those with the GG genotype. In addition, significant associations were found between type 2 diabetes mellitus, hypertension, and hyperlipidemia with TCF21 gene polymorphisms (p for trend < 0.05). Conclusion: TCF21 gene polymorphisms may increase susceptibility to stable angina and STEMI.

Loss of ficolin-3 expression is associated with poor prognosis in patients with hepatocellular carcinoma.

Background: Ficolin-3 (FCN3) is a well-known circulating pattern recognition molecule which plays a role in host immune responses to cancer via activation of the lectin complement pathway. Nevertheless, the clinical significance of FCN3 in patients with hepatocellular carcinoma (HCC) is unclear. Methods: Eighty-seven HCC patients who received hepatectomy at our hospital were included. Immunohistochemical staining was used to assess the FCN3 expression in both tumorous and non-tumorous tissues from the patients, who were classified into high and low expression groups. Differences in clinicopathological characteristics between the two groups were then analyzed. Results: Survival was significantly associated with FCN3 immunohistochemical score (p for trend = 0.048). Kaplan-Meier analysis revealed a higher overall survival rate in the patients with a high FCN3 expression than in those with a low FCN3 expression (p=0.031). A high FCN3 expression in tumor tissue was independently associated with better overall survival (p=0.042). However, multivariate analysis showed that FCN3 expression was not an independent risk factor for overall survival. Conclusion: Our findings suggest that FCN3 is significantly related to the prognosis of HCC. FCN3 may be a prognostic marker in patients with HCC.

Global, regional, and national burden of kidney dysfunction from 1990 to 2019: a systematic analysis from the global burden of disease study 2019.

OBJECTIVE: We aim to explore the prevalence and temporal trends of the burden of kidney dysfunction (KD) in global, regional and national level, since a lack of related studies. DESIGN: Cross-sectional study. MATERIALS: The data of this research was obtained from Global Burden of Diseases Study 2019. The estimation of the prevalence, which was measured by the summary exposure value (SEV), and attributable burden of KD was performed by DisMod-MR 2.1, a Bayesian meta-regression tool. The Spearman rank order correlation method was adopted to perform correlation analysis. The temporal trends were represented by the estimated annual percentage change (EAPC). RESULTS: In 2019, there were total 3.16 million deaths and 76.5 million disability-adjusted life years (DALYs) attributable to KD, increased by 101.1% and 81.7% compared with that in 1990, respectively. From 1990 to 2019, the prevalence of KD has increased in worldwide, but decreased in High-income Asia Pacific. Nearly 48.5% of countries globally, such as South Africa, Egypt and Mexico had increased mortality rates of KD from 1990 to 2019 while 44.6% for disability rate. Countries with lower socio-demographic index (SDI) are facing a higher prevalence as well as mortality and disability rate compared with those with higher SDI. Compared with females, the prevalence of KD was lower in males, however the attributable mortality and disability rate were higher in all years from 1990 to 2019. CONCLUSION: With the progress of senescent, we will face more severe challenges of reducing the prevalence and attributable burden of KD, especially in regions with lower SDI. Effective measures are urgently required to alleviate the prevalence and burden of KD.

Elevated plasma leptin levels are associated with vascular access dysfunction in patients on maintenance hemodialysis.

BACKGROUND: Inflammation has been associated with vascular access (VA) dysfunction. The adipocytokine leptin can directly induce pro-inflammatory T helper 1 immune responses and the pathogenesis of chronic inflammation. We explored the association between plasma leptin and VA dysfunction in patients on maintenance hemodialysis (HEMO). METHODS: A total of 344 consecutive patients who received anastomosis for VA at a single HEMO center between June 1, 2010 and December 31, 2021 were screened. Of these patients, 267 met the inclusion criteria and were included. ELISA was used to measure circulating levels of leptin. RESULTS: The VA dysfunction group had a higher leptin level than the patent VA group. A higher concentration of leptin was independently and significantly associated with an elevated risk of VA dysfunction. Multiple logistic regression analysis showed that leptin, female sex, and hypertension were independently associated with VA dysfunction, even after adjusting for known biomarkers. We then evaluated the ability of leptin, female sex, and hypertension to predict the risk of VA dysfunction, and the area under the curve (AUC) for leptin was 0.626 (p = 0.0001). When leptin, female sex, and hypertension were added to this multivariate model, the AUC increased to 0.679 (p = 0.001) for leptin and hypertension, and 0.690 for leptin, hypertension, and female sex (p = 0.004). In addition, plasma leptin levels were associated with sex, body mass index, and hemoglobin. CONCLUSIONS: In addition to the association between leptin and VA dysfunction, hypertension and female sex independently predicted VA dysfunction in patients with HEMO.

Understanding Breast Cancer Disparities Affecting Black Women: Obtaining Diverse Perspectives Through Focus Groups Comprised of Patients, Providers, and Others.

Black women have the highest death rate from breast cancer and a higher chance of developing breast cancer before the age of 40 than White women. Mammography screening is recommended for early detection which has led to decreased mortality and improved survival. Unfortunately, Black women are less likely to have breast cancer screenings. Environmental justice communities represent place-based structural disparity/racism leading to health inequality. Environmental justice specifically addresses situations where minority or low-income communities bear disproportionately poor human health outcomes and environmental risks. The purpose of this qualitative study was to gain a deep understanding of breast cancer screening disparity from multiple perspectives to enable collective solutions to barriers faced by Black women in an environmental justice community. Data were collected from 22 participants using a focus group approach from Black women with breast cancer (n = 5) and without it (n = 5), healthcare providers (n = 6), and community leaders (n = 6). An iterative and inductive thematic data analysis method was used to analyze data. The themes that emerged from the data included: (1) misconceptions and fear of mammograms; (2) breast cancer screening beyond mammograms; and (3) barriers beyond mammograms. These themes reflected personal, community, and policy barriers leading to breast cancer screening disparity. This study was an initial step to develop multi-level interventions targeting the personal, community, and policy barriers that are needed to advance breast cancer screening equity for Black women living in environmental justice communities.

Plasma levels and tissue expression of liver-type fatty acid-binding protein in patients with breast cancer.

BACKGROUND: Liver-type fatty acid-binding protein (L-FABP) is widely expressed in hepatocytes and plays a role in lipid metabolism. It has been demonstrated to be overexpressed in different types of cancer; however, few studies have investigated the association between L-FABP and breast cancer. The aim of this study was to assess the association between plasma concentrations of L-FABP in breast cancer patients and the expression of L-FABP in breast cancer tissue. METHOD: A total of 196 patients with breast cancer and 57 age-matched control subjects were studied. Plasma L-FABP concentrations were measured using ELISA in both groups. The expression of L-FABP in breast cancer tissue was examined using immunohistochemistry. RESULT: The patients had higher plasma L-FABP levels than the controls (7.6 ng/mL (interquartile range 5.2-12.1) vs. 6.3 ng/mL (interquartile range 5.3-8.5), p = 0.008). Multiple logistic regression analysis showed an independent association between L-FABP and breast cancer, even after adjusting for known biomarkers. Moreover, the rates of pathologic stage T2+T3+T4, clinical stage III, positive HER-2 receptor status, and negative estrogen receptor status were significantly higher in the patients with an L-FABP level greater than the median. Furthermore, the L-FABP level gradually increased with the increasing stage. In addition, L-FABP was detected in the cytoplasm, nuclear, or both cytoplasm and nuclear of all breast cancer tissue examined, not in the normal tissue. CONCLUSIONS: Plasma L-FABP levels were significantly higher in the patients with breast cancer than in the controls. In addition, L-FABP was expressed in breast cancer tissue, which suggests that L-FABP may be involved in the pathogenesis of breast cancer.

Tracking Symptoms of Patients With Lymphedema Before and After Power-Assisted Liposuction Surgery.

PURPOSE: Lymphedema negatively impacts patients from a psychosocial standpoint and consequently affects patient's quality of life. Debulking procedures using power-assisted liposuction (PAL) are currently deemed an effective treatment for fat-dominant lymphedema and improves anthropometric measurements as well as quality of life. However, there have been no studies specifically evaluating changes in symptoms related to lymphedema after PAL. An understanding of how symptoms change after this procedure would be valuable for preoperative counseling and to guide patient expectations. METHODS: A cross-sectional study was performed in patients with extremity lymphedema who underwent PAL from January 2018 to December 2020 at a tertiary care facility. A retrospective chart review and follow-up phone survey were conducted to compare signs and symptoms related to lymphedema before and after PAL. RESULTS: Forty-five patients were included in this study. Of these, 27 patients (60%) underwent upper extremity PAL and 18 patients (40%) underwent lower extremity PAL. The mean follow-up time was 15.5±7.9 months. After PAL, patients with upper extremity lymphedema reported having resolved heaviness (44%), as well as improved achiness (79%) and swelling (78%). In patients with lower extremity lymphedema, they reported having improved all signs and symptoms, particularly swelling (78%), tightness (72%), and achiness (71%). CONCLUSIONS: In patients with fat-dominant lymphedema, PAL positively impacts patient-reported outcomes in a sustained fashion over time. Continuous surveillance of postoperative studies is required to elucidate factors independently associated with the outcomes found in our study. Moreover, further studies using a mixed method approach will help us better understand patient's expectations to achieve informed decision and adequate treatment goals.

Rutin alleviates bisphenol A-glycidyl methacrylate-induced generation of proinflammatory mediators through the MAPK and NF-κB pathways in macrophages.

Bisphenol A-glycidyl methacrylate (BisGMA) is a methacrylate monomer that is mainly used in three-dimensional structures to reconstruct dental and bony defects. BisGMA has toxic and proinflammatory effects on macrophages. Rutin is a natural flavonol glycoside that is present in various plants and has useful biological effects, such as anti-inflammatory, anticancer, and antioxidative effects. The aim of this study was to investigate the anti-inflammation of rutin in macrophages after exposure to BisGMA. Pretreatment of the RAW264.7 macrophage with rutin at 0, 10, 30, and 100 µM for 30 min before being incubated with BisGMA at 0 or 3 µM. Proinflammatory cytokines and prostaglandin (PG) E2 were detected by enzyme-linked immunosorbent assay (ELISA). Nitric oxide (NO) was detected by the Griess assay. Expression and phosphorylation of proteins were measured by Western blot assay. Pretreatment with rutin inhibited the BisGMA-induced generation of proinflammatory cytokines, including tumor necrosis factor (TNF)-α, interleukin (IL)-1ß, IL-6, and PGE2, in macrophages. Rutin also suppressed the BisGMA-induced secretion of NO and expression of inducible nitric oxide synthase (iNOS) in a concentration-dependent manner. Furthermore, rutin suppressed the mitogen-activated protein kinase (MAPK) phosphorylation in a concentration-dependent manner. Finally, rutin suppressed the BisGMA-induced phosphorylation of nuclear factor (NF)-κB p65 and degradation of inhibitor of κB (IκB). These results indicate that the concentration of rutin has an inhibitory effect on proinflammatory mediator generation, MAPK phosphorylation, NF-κB p65 phosphorylation, and IκB degradation. In conclusion, rutin is a potential anti-inflammatory agent for BisGMA-stimulated macrophages through NF-κB p65 phosphorylation and IκB degradation resulting from MAPK phosphorylation.

Comparative Transcriptome Analysis of Purple and Green Flowering Chinese Cabbage and Functional Analyses of BrMYB114 Gene.

Flowering Chinese cabbage (Brassica rapa var. parachinensis) is one of the most popular vegetables in the south of China. As an antioxidant, anthocyanin is an important quality trait in vegetables, and the gene related to anthocyanin biosynthesis in purple flowering Chinese cabbage is also important. In this study, two flowering Chinese cabbage with extreme colors in the stem were used as materials for transcriptome analysis. RNA-seq analysis showed that 6811 differentially expressed genes (DEGs) were identified, including 295 transcription factors. Phenylpropanoid biosynthesis, flavone and flavanol biosynthesis, and flavonoid biosynthesis pathways were found to be significantly enriched in the purple flowering Chinese cabbage. A total of 25 DEGs associated with anthocyanin biosynthesis were found at a higher expression in purple flowering Chinese cabbage than in green flowering Chinese cabbage. Bioinformatics analysis shows that BrMYB114 is a candidate gene for the regulation of anthocyanin biosynthesis, and heterologous expression analysis of BrMYB114 in Nicotiana benthamiana indicates that BrMYB114 functions in anthocyanin biosynthesis. Therefore, our findings provide vital evidence for elucidating the molecular mechanism in the purple stem in flowering Chinese cabbage.

A Novel Zwitterionic Hydrogel Incorporated with Graphene Oxide for Bone Tissue Engineering: Synthesis, Characterization, and Promotion of Osteogenic Differentiation of Bone Mesenchymal Stem Cells.

Zwitterionic materials are widely applied in the biomedical field due to their excellent antimicrobial, non-cytotoxicity, and antifouling properties but have never been applied in bone tissue engineering. In this study, we synthesized a novel zwitterionic hydrogel incorporated with graphene oxide (GO) using maleic anhydride (MA) as a cross-linking agent by grafted L-cysteine (L-Cys) as the zwitterionic material on maleilated chitosan via click chemistry. The composition and each reaction procedure of the novel zwitterionic hydrogel were characterized via X-ray diffraction (XRD) and Fourier transformed infrared spectroscopy (FT-IR), while the morphology was imaged by scanning electron microscope (SEM). In vitro cell studies, CCK-8 and live/dead assay, alkaline phosphatase activity, W-B, and qRT-CR tests showed zwitterionic hydrogel incorporated with GO remarkably enhanced the osteogenic differentiation of bone mesenchymal stem cells (BMSCs); it is dose-dependent, and 2 mg/mL GO is the optimum concentration. In vivo tests also indicated the same results. Hence, these results suggested the novel zwitterionic hydrogel exhibited porous characteristics similar to natural bone tissue. In conclusion, the zwitterionic scaffold has highly biocompatible and mechanical properties. When GO was incorporated in this zwitterionic scaffold, the zwitterionic scaffold slows down the release rate and reduces the cytotoxicity of GO. Zwitterions and GO synergistically promote the proliferation and osteogenic differentiation of rBMSCs in vivo and in vitro. The optimal concentration is 2 mg/mL GO.

Sociodemographic characteristics, lifestyle behaviors, and symptoms associated with fluid overload among non-hospitalized and community-dwelling older adults with heart failure: A population-based approach.

BACKGROUND: Fluid overload is a major complication in patients with heart failure (HF) and the main reason for hospitalization. The purpose of the study was to explore the associations of fluid overload with sociodemographic characteristics, lifestyle behaviors, and symptoms among non-hospitalized and community-dwelling older adults with HF using large population data. METHODS: Descriptive and multivariate analyses were conducted on the Health and Retirement Study 2016. RESULTS: Fluid overload was prevalent in almost half of the sample. Female older adults with HF were more likely to have fluid overload (OR:1.43, p = 0.037) as well as being Black (OR:1.40, p = 0.041). Higher physical activity scores were associated with less likelihood of having fluid overload (OR:0.99, p = 0.025). Symptoms of shortness of breath (OR=2.18, p = 0.001), pain (OR=1.82, p < 0.001), and fatigue (OR=1.45, p = 0.025) were significantly associated with fluid overload. CONCLUSION: Female and Black community-dwelling older adults with HF are at higher risk of fluid overload. Symptoms of shortness of breath, pain, and fatigue are significant manifestations of fluid overload. Effective patient-centered interventions to promote fluid flow via physical activity may help older adults with HF manage fluid overload and alleviate associated symptoms.

Impact of Co-occurring Cancer-Related and Wound-Specific Symptoms on Functional Performance Among Patients With Advanced Cancer and Malignant Fungating Wounds: An Exploratory, Observational Study.

PURPOSE: The purpose of this study was to examine the impact of co-occurring symptoms in patients with advanced cancer and malignant fungating wounds (MFWs) on palliative and functional performance, and the feasibility of collecting self-reported data in this population. DESIGN: This was an exploratory, observational study. Quantitative surveys and qualitative semistructured interviews using a phenomenological approach were employed. SUBJECTS AND SETTING: The sample comprised 5 adults with advanced breast, oral, and ovarian cancer and MFWs. Participants were recruited from an urban outpatient cancer center, hospice, and wound center located in the Northeastern United States. METHODS: Demographic and clinical characteristics were collected, and self-reported symptom and functional performance data measured. Descriptive statistics, T scores, confidence intervals, and standard deviation were calculated for quantitative data. One-to-one semistructured interviews were conducted by the first author to gain deeper understanding of participants' symptom experience. Qualitative data were analyzed using an iterative and inductive thematic data analysis method to identify major themes. RESULTS: The mean cancer-related and wound-specific symptom occurrence was 17 (SD = 5.56) and 4 (SD = 1.26), respectively. Distressing, extensive co-occurring symptom burdens were experienced by all participants; they also reported poor functional performance and diminished palliative performance. Qualitative findings supported quantitative results. CONCLUSIONS: Findings suggest that co-occurring cancer-related and wound-specific symptoms have incremental and negative impact on functional performance. The use of multiple data collection methods was feasible, including self-reported data in this advanced cancer population.

A Pilot Qualitative Case Study of Women's Experiences with Fertility Awareness-Based Methods.

This pilot qualitative case study was able to elicit rich data enabling a description of how women went through the journey of achieving pregnancy using fertility awareness-based methods. Findings underscore that women preferred using natural ways to detect ovulation and would recommend other women to do so, but with healthcare providers' guidance. The findings of this case study can serve as a starting point to provide a framework to understand women's experiences of enduring trial and error with multiple fertility awareness-based methods before discovering their effective method. Findings emphasize the importance for healthcare providers to guide women in using fertility awareness-based methods.

Oral mycobiota and pancreatic ductal adenocarcinoma.

Early detection of pancreatic ductal adenocarcinoma (PDAC) is essential for survival. Preliminary research demonstrated significant associations between structural alternation of mycobiota and PDAC. In this study, we investigated the associations between oral mycobiota and PDAC. We further explored mycobiota biomarkers for PDAC detection. We enrolled 34 PDAC patients and 35 matched healthy controls from West China hospital in Southwest China. Demographic data, clinical information, and salivary samples were collected. Mycobiota characteristics were defined using Internal Transcribed Spacer (ITS) ribosomal RNA sequencing. We found that the PDAC patients had significant increase in fungal abundance (P < 0.001) and significant decrease in fungal diversity (P < 0.001) in comparison to the healthy controls. A higher abundance of Basidiomycota and Unclassifed_p_Ascomycota was associated with an increased risk of PDAC. With each increase of abundance of g__unclassified_k__Fungi and g__unclassified_p__Ascomycota in PDAC patients, the risk of pancreatic cancer increased by 1.359 odds and 1.260 odds, respectively. Aspergillus (AUC = 0.983, 95% CI 0.951-1.000) and Cladosporium (AUC = 0.969, 95% CI 0.921-1.000) achieved high classification powers to distinguish PDAC patients from the healthy controls. The rapid, inexpensive tests of ITS1 sequencing of mycobiota and PCR detection of potential fungal biomarkers make it promising for the clinical practice to use oral microbes for PDAC early detection and prevention. Results of our study provide evidence that salivary mycobiota may provide insights into cancer risk, prevention, and detection.

Fibroblast growth factor 21 is associated with widening QRS complex and prolonged corrected QT interval in patients with stable angina.

BACKGROUND: Fibroblast growth factor 21 (FGF21) is produced by cardiac cells, may acts in an autocrine manner, and was suggested to has a cardioprotective role in atherosclerosis. Wide QRS complex and heart rate-corrected QT interval (QTc interval) prolongation are associated to dangerous ventricular arrhythmias and cardiovascular disease mortality. Yet, the role of FGF21 in cardiac arrhythmia has never been studied. The aim of the study was to investigate the relationship between plasma FGF21 and the QRS duration and QTc interval in patients with stable angina. METHODS: Three hundred twenty-one consecutive stable angina patients were investigated. Plasma FGF21 was measured through ELISA, and each subject underwent 12-lead electrocardiography. RESULTS: FGF21 plasma levels were positively associated with the QRS duration (ß = 0.190, P = 0.001) and QTc interval (ß = 0.277, P < 0.0001). With increasing FGF21 tertiles, the patients had higher frequencies of wide QRS complex and prolonged QTc interval. After adjusting for patients' anthropometric parameters, the corresponding odd ratios (ORs) for wide QRS complex of the medium and high of FGF21 versus the low of FGF21 were 1.39 (95% CI 0.51-3.90) and 4.41 (95% CI 1.84-11.59), respectively, and p for trend was 0.001. Furthermore, multiple logistic regression analysis also showed the corresponding odd ratios (ORs) for prolonged QTc interval of the medium and high of FGF21 versus the low of FGF21 were 1.02 (95% CI 0.53-1.78) and 1.93 (95% CI 1.04-3.60) respectively with the p for trend of 0.037. In addition, age- and sex-adjusted FGF21 levels were positively associated with fasting glucose, HbA1c, creatinine, and adiponectin, but negatively associated with albumin, and the estimated glomerular filtration rate. CONCLUSIONS: This study indicates that plasma FGF21 is associated with wide QRS complex and prolonged corrected QT interval in stable angina patients, further study is required to investigate the role of plasma FGF21 for the underlying pathogenesis.

Association of plasma fatty acid-binding protein 3 with estimated glomerular filtration rate in patients with type 2 diabetes mellitus.

Background: Fatty acid-binding protein 3 (FABP3) located in renal mesangial and distal tubular cells, and had been shown to be a sensitive marker of renal injury, potentially be a mediator in pathogenesis of chronic kidney disease (CKD). Our previous study revealed that plasma FABP1 and FABP2 were independently associated with CKD, however, little is known about the relationship between plasma FABP3 level and CKD. The aim of this study was therefore to evaluate the plasma levels of FABP3 at different stages of estimated glomerular filtration rate (eGFR) in patients with type 2 diabetes mellitus (T2DM). Methods: A total of 334 subjects with T2DM who enrolled in a disease management program were included in this study and stratified according to eGFR. Plasma FABP3 concentrations were measured by an enzyme-linked immunosorbent assay. Results: FABP3 levels increased in parallel with the eGFR level. Increasing concentrations of FABP3 were independently and significantly associated with eGFR stage G2-G4. Age- and sex-adjusted FABP3 levels were positively associated with uric acid, urinary albumin-to-creatinine ratio, FABP1, FABP2, and fatty liver index, but negatively associated with eGFR and hemoglobin. Conclusion: Our results indicate that circulating FABP3 in patients with T2DM is associated with eGFR, which suggests that increased plasma FABP3 may be involved in the pathogenesis of CKD.

Interactive effect of obesity and cognitive function decline on the risk of chronic kidney disease progression in patients with type 2 diabetes mellitus: a 9.1-year cohort study.

Background: Obesity and cognitive function decline are independent risk factors for chronic kidney disease (CKD). However, few studies have examined the combined effects of obesity status and cognitive function on change in CKD risk. We aimed to evaluate the association between obesity status, cognitive function and CKD risk change in patients with type 2 diabetes mellitus (T2DM). Methods: Data on 3399 T2DM patients were extracted from a diabetes disease management program between 2006 and 2018. Univariate and multivariate analyses were used to assess the association between obesity, cognitive decline, and CKD risk change. Three indexes, including the relative excess risk of interaction (RERI), attributable proportion of interaction (API), and synergy index (SI), were used to analyze interactions. CKD risk was classified according to the KDIGO 2012 CKD definition. Results: In multivariate analysis, the hazard ratio (HR, 95%Cis) for CKD risk progression was 1.34 (1.12-1.61) times higher in the moderate and severely obese patients compared with the normal weight patients, and 1.34 (1.06-1.67) times higher in the patients with a Mini-Mental State Examination (MMSE) score ≤18 compared to those with an MMSE score ≥24. There was a synergistic interaction between moderate and severe obesity and MMSE score ≤18 on CKD risk progression (SI=4.461; 95% CI: 1.998-9.962), and the proportion of CKD risk progression caused by this interaction was 52.7% (API=0.527; 95% CI: 0.295-0.759). However, normal weight and MMSE score ≥24 were not beneficial on CKD risk improvement in the patients with a moderate risk and very high-risk stage of CKD. Conclusion: There may be a synergistic interaction between obesity and cognitive function decline, and the synergistic interaction may increase the risk of CKD progression.

Anophthalmia Caused by Familial Homozygous Mutation of VSX2: a Case Report.

BACKGROUND: Although rare, several mutations in the gene VSX2 (visual system homeobox 2, formerly CHX10) have been associated with congenital autosomal recessive anophthalmia (absence of one or both eyes). This report describes a proband, who at presentation was gravida 2, para 0, and 30 weeks pregnant. METHODS: A 30-year-old woman with congenital bilateral anophthalmia was 30 weeks pregnant at the time of presentation. Her parents were fourth-generation collateral blood relatives, and the familial congenital disease history suggested a possible genetic cause for her anophthalmia. Next generation sequencing and Sanger sequencing of blood samples of the patient, her parents, and her husband were conducted. The fetus was examined via ultrasound. RESULTS: The woman patient had a homozygous variation of the VSX2 gene (NM_182894.2) c.634delC (p.R211 Gfs*90). Both of her parents carried a heterozygous variation of this locus. The husband showed no pathogenic variation in VSX2. The fetal ultrasound revealed bilateral eyeball lenses. A healthy girl was delivered at 41 weeks gestation, with bilateral eyeballs visible. CONCLUSIONS: Homogenous mutation of VSX2 c.634delC (p.R211Gfs*90) has not been reported previously. The patient's congenital bilateral anophthalmia was due to this homogenous mutation, the result of familial inbreeding. Avoiding near-relative marriage is an important means of preventing such diseases.
