Background: Elevated fibroblast growth factor 21 (FGF21) levels have been suggested, from cross-sectional studies, as an indicator of subclinical diabetic nephropathy. We investigated whether serum FGF21 was predictive of the development of diabetic nephropathy. Method: Baseline serum FGF21 levels were measured in 1136 Chinese type 2 diabetic subjects recruited from the Hong Kong West Diabetes Registry. The role of serum FGF21 in predicting decline in estimated glomerular filtration rate (eGFR) over a median follow-up of 4 years was analyzed using Cox regression analysis. Results: At baseline, serum FGF21 levels increased progressively with eGFR category (P for trend <.001). Among 1071 subjects with baseline eGFR ≥ 30 mL/min/1.73 m2, serum FGF21 levels were significantly higher in those with eGFR decline during follow-up (n = 171) than those without decline (n = 900) (P < .001). In multivariable Cox regression analysis, baseline serum FGF21 was independently associated with eGFR decline (hazard ratio, 1.21; 95% confidence interval [CI], 1.01–1.43; P = .036), even after adjustment for baseline eGFR. In a subgroup of 559 subjects with baseline eGFR ≥60 mL/min/1.73 m2 and normoalbuminuria, serum FGF21 level remained an independent predictor of eGFR decline (hazard ratio, 1.36; 95% CI, 1.06–1.76; P = .016). Integrated discrimination improvement (IDI) suggested that the inclusion of baseline serum FGF21 significantly improved the prediction of eGFR decline (IDI, 1%; 95% CI, 0.1–3.0; P = .013) in this subgroup, but not in the initial cohort involving all subjects. Conclusions: Elevated serum FGF21 levels may be a useful biomarker for predicting kidney disease progression, especially in the early stages of diabetic nephropathy.

Background: The survival rate of elderly hemodialyzed (HD) patients is commonly thought to be poor. In a prospective, single center, non-interventional, observational study, the cause of all-cause and cardiovascular (CV) and heart failure (HF) mortality in this patient group were examined and compared with a younger cohort (below 60 years). Material/Methods: The study included 223 patients (90 women and 133 men) with age ranging from 34.5 to 75.0 years treated with HD. Median duration of HD was 70.0 months (24.0-120.0). Mortality data was collected over a period of six years. We divided patients into groups: <60 (n=123), ≥60 years (n=100), and with (n=33) and without DM type 2 (n=190). Results: During a six-year follow-up, 100 patients (44.8%) died, including 83 (37.2%) patients who died due to CV reasons. Median follow-up was 2015.0 days (946.0-2463.0) with the median time to death of 1166.0 days (654.5-1631.0). The factors negatively affecting patients’ survival in univariate Cox regression analysis included for all-cause mortality were: inter-dialytic weight gain (IDWG) (hazard ratio [HR]=1.60; p=0.01), ultrafiltration (UF) rate (HR=3.63; p=0.012) for group <60 years; for CV death: UF rate (HR=4.20; p=0.03), DM (HR=5.11; p=0.002) for group <60 years; for HF death: mellitus type 2 (DM) (HR=2.93; p=0.027) for group ≥60 years). In a multivariate Cox regression analysis for patients <60 years, the UF rate was the only independent predictor of all-cause mortality (HR 3.63 (1.34-9.67); p=0.011). Both DM (HR 4.91 (1.71-14.10); p=0.003) and UF rate (HR 3.62 (1.04-12.61); p=0.044) were independent predictors of CV-related mortality in patients <60 years. Conclusions: The UF rate can be a simple, useful indicator of higher long-term all-cause and CV mortality in HD patients <60 years of age. Also, DM may be a predictor of CV–related mortality in younger HD patients.

IntroductionTrigger finger is one of the complications affecting the upper extremity in patients with diabetes. Diabetes is also a well-known risk factor that predisposes individuals to cardiovascular diseases (CVDs). This retrospective cohort study aimed to establish the association between trigger finger and the patients with incident CVD with type 2 diabetes.Materials and methodsTrigger finger was diagnosed by palpating a thickened tendon during flexion or on the manifestation of a locking phenomenon during extension or flexion of either finger. The relationship between trigger finger and other clinical parameters or complications of diabetes was examined by a comparative analysis. Cox regression analysis was used to evaluate the association between trigger finger and incidence of CVD. We calculated the propensity scores using sex, body mass index, age, smoking status, duration of diabetes, estimated glomerular filtration rate, hypertension, dyslipidemia, and hemoglobin A1c as the number of patients with incident CVD during the follow-up period was low.ResultsAmong the 399 patients with type 2 diabetes, 54 patients had trigger finger. Patients with trigger finger were significantly older in age and had been suffering from diabetes for a longer duration. They also displayed worse renal function and glycemic control, along with a higher incidence of hypertension, neuropathy and nephropathy. During the average 5.66±1.12 years of follow-up, a total of 18 incidents occurred. According to the Cox regression analysis, trigger finger was shown to be associated with enhanced risk of the incidence of CVD after adjustment for the covariates (adjusted HR=3.33 (95% CI 1.25 to 8.66), p=0.017).ConclusionsTrigger finger is associated with the risk of incident CVD in patients with type 2 diabetes. Thus, clinicians must consider these factors at the time of diagnosis of such patients.

Background: Depression and anxiety after stroke are common conditions that are likely to be neglected. Abnormal red blood cell (RBC) indices may be associated with neuropsychiatric disorders. However, the association of RBC indices with post-stroke depression (PSD) and poststroke anxiety (PSA) has not been sufficiently investigated. Methods: We aimed to investigate the trajectory of post-stroke depression and anxiety in our follow- up stroke clinic at 1, 3, and 6 months, and the association of RBC indices with these. One hundred and sixty-two patients with a new diagnosis of ischemic stroke were followed up at 1, 3, and 6 months, and underwent Patient Health Questionnaire-9 (PHQ-9) and the general anxiety disorder 7-item (GAD-7) questionnaire for evaluation of depression and anxiety, respectively. First, we used Kaplan-Meier analysis to investigate the accumulated incidences of post-stroke depression and post-stroke anxiety. Next, to explore the association of RBC indices with psychiatric disorders after an ischemic stroke attack, we adjusted for demographic and vascular risk factors using multivariate Cox regression analysis. Results: Of the 162 patients with new-onset of ischemic stroke, we found the accumulated incidence rates of PSD (1.2%, 17.9%, and 35.8%) and PSA (1.2%, 13.6%, and 15.4%) at 1, 3, and 6 months, respectively. The incident PSD and PSA increased 3 months after a stroke attack. Multivariate Cox regression analysis indicated independent positive associations between PSD risk and higher mean corpuscular volume (MCV) (OR=1.42, 95% CI=1.16-1.76), older age (OR=2.63, 95% CI=1.16-5.93), and a negative relationship between male sex (OR=0.95, 95% CI=0.91-0.99) and PSA. Conclusion: The risks of PSD and PSA increased substantially 3 months beyond stroke onset. Of the RBC indices, higher MCV, showed an independent positive association with PSD.

The use of hydraulic silicate cements (HSCs) for vital pulp therapy has been found to release calcium and hydroxyl ions promoting pulp tissue healing and mineralized tissue formation. The present study investigated whether HSCs such as mineral trioxide aggregate (MTA) affect their biological and antimicrobial properties when used as long-term pulp protection materials. The effect of variables on treatment outcomes of three HSCs (ProRoot MTA, OrthoMTA, and RetroMTA) was evaluated clinically and radiographically over a 48–78 month follow-up period. Survival analysis was performed using Kaplan–Meier survival curves. Fisher’s exact test and Cox regression analysis were used to determine hazard ratios of clinical variables. The overall success rate of MTA partial pulpotomy was 89.3%; Cumulative success rates of the three HSCs were not statistically different when analyzed by Cox proportional hazard regression analysis. None of the investigated clinical variables affected success rates significantly. These HSCs showed favorable biocompatibility and antimicrobial properties in partial pulpotomy of permanent teeth in long-term follow-up, with no statistical differences between clinical factors.

Abstract Background: Cytokine storm triggered by Severe Corona Virus Disease 2019 (COVID-19) is associated with high mortality. With high ‘Interlukin -6’ (IL-6) levels reported in COVID-19 deaths in China1, IL-6 is considered to be the key player in COVID-19 cytokine storm. Tocilizumab, a monoclonal antibody against IL-6 receptor, is used on compassionate grounds for treatment of COVID-19 cytokine storm. Aim of this study was to assess effect of tocilizumab on mortality due to COVID-19 cytokine storm.Method: This retrospective, observational study included patients of severe COVID-19 pneumonia with persistent hypoxia (defined as saturation 94% or less on supplemental Oxygen of 15 L per minute through non-rebreathing mask or PaO2/FiO2 ratio of less than 200) who were admitted to tertiary care center in Mumbai, India, between 31st March to 5th July 2020. In addition to standard care, single Inj. Tocilizumab 400mg was given intravenously to 151 consecutive COVID-19 patients with persistent hypoxia from 13th May to 5th July 2020. These 151 patients were retrospectively analysed and compared with historic controls i.e consecutive COVID-19 patients with persistent hypoxia, defined as above (N=118, from our first COVID-19 admission on 31st March to 12th May 2020 ie till tocilizumab was available in hospital). Univariate and multivariate Cox regression analysis was performed for identifying predictors of survival. Statistical analysis was performed using IBM SPSS version 26.Results: On multivariate Cox regression analysis, independent predictors of survival were use of tocilizumab (HR 0.621, 95% CI 0.427-0.903, P 0.013) and higher oxygen saturation.Conclusion: Tocilizumab improved survival in severe COVID-19 pneumonia with persistent hypoxia

The majority of patients with myelodysplastic syndromes (MDS) require regular red blood cell (RBC) transfusions. Alloimmunization (AI) against blood products is an adverse event, causing time-consuming RBC compatibility testing. The reported incidence of AI in MDS patients varies greatly. Even though different studies on AI in MDS patients have been performed, there are still knowledge gaps. Current literature has not yet fully identified the risk factors and dynamics of AI in individual patients, nor has the influence of disease modifying treatment (DMT) been explored. Therefore, we performed this study to evaluate the effect of DMT on AI. An observational, population-based study, using the HemoBase registry, was performed including all newly diagnosed MDS patients between 2005 and 2017 in Friesland, a province of the Netherlands. All available information about treatment and transfusions, including transfusion dates, types, and treatment regimens, was collected from the electronic health records and laboratory systems. Follow-up occurred through March 2019. For our patient cohort, blood products were matched for AB0 and RhD, and transfused per the 'type and screen' policy (i.e. electronic matching of blood group phenotype between patient and donor). After a positive antibody screening, antibody identification and Rh/K phenotyping was performed and subsequent blood products were (cross)matched accordingly. The observation period was counted from first transfusion until last transfusion or first AI event. Univariate analyses and cumulative frequency distributions were performed to study possible risk factors and dynamics of AI. DMT was defined as hypomethylating agents, lenalidomide, chemotherapy and monoclonal antibodies. The effect of DMT as a temporary risk period on the risk of AI was estimated with incidence rates, relative risks (RR) and hazard ratios (HR) using a cox regression analysis. Follow-up was limited to 24 months for the cox regression analysis to avoid possible bias by survival differences. Statistical analyses were performed using IBM SPSS 24 and SAS 9.4. Out of 292 MDS patients, 236 patients received transfusions and were included in this study, covering 463 years of follow-up. AI occurred in 24 patients (10%). AI occurred mostly in the beginning of the observation period: Eighteen patients (75%) were alloimmunized after receiving 20 units of RBCs, whereas 22 patients (92%) showed AI after 45 units of RBCs (Figure 1). We found no significant risk factors for AI in MDS patients at baseline. DMT was given to 67 patients (28%) during the observation period. Patients on DMT received more RBC transfusions than patients that did not receive DMT (median of 33 (range: 3-154) and 11 (range: 0-322) RBC units respectively, p<0,001). Four AI events (6%) occurred in patients on DMT and 20 AI events (12%) occurred in patients not on DMT. Cox regression analysis of the first 24 months of follow-up showed an HR of 0.30 (95% CI: 0.07-1.31; p=0.11). The incidence rates per 100 person-years were 3.19 and 5.92 respectively. The corresponding RR was 0.54 (95% CI: 0.16-1.48; p=0.26). Based on our results, we conclude that the incidence of AI in an unselected, real world MDS population receiving RBC transfusions is 10% and predominantly occurred in the beginning of follow-up. Risk factors for AI at baseline could not be identified. Our data showed that patients on DMT received significantly more RBC transfusions but were less susceptible to AI. Therefore, extensive matching of blood products may not be necessary for patients on DMT. Larger studies are needed to confirm the protective effect of DMT on AI.

Background: GDF15 belongs to the transforming growth factor superfamily and has a significant role in regulating inflammatory and apoptotic pathways. GDF15 is an emerging biomarker for risk stratification in cardiovascular disease. Here we analyze its prognostic value in patients with severe symptomatic aortic valve stenosis undergoing transcatheter aortic valve implantation (TAVI). Methods and Results: We prospectively enrolled 217 patients undergoing TAVI (using Edwards Sapien XT prostheses) at our institution over a continuous period of 35 month (2/2011-12/2013). All patients were available for complete follow up. Clinical parameters were determined before the procedure, biomarkers (GDF15 & NTproBNP) were measured before, 3 and 7 days after TAVI. The primary endpoint was survival time, all available prognostic factors were studied by Cox regression analysis with backward selection based on the likelihood ratio criteria. At median follow-up of 349 d (Q1-Q3 106-660d), a total of n=66 deaths occurred. 30d mortality was 6.9%. Mean age was 81.8 years (± 6.0 y) and 55.8% were females. Mean log. Euroscore (ES) was 25.4% (± 17.2%). Median preprocedural GDF15 values were 2256 pg/ml (Q1-Q3 1585.5-3082.0). In univariate analyses, increased GDF15 levels (upper quartile compared to lower three quartiles) revealed a HR of 2.4 (CI 1.5-3.9, p<0.001) for adverse outcome. In addition, also log. ES (p= 0.001), log. ES II (p=0.018), STS-Score (p=0.019), NTproBNP (p=0.037) and atrial fibrillation (p=0.02) demonstrated statistical significance for negative outcome. A multivariate Cox regression analysis including these factors and postprocedural aortic regurgitation, demonstrated that elevated GDF15 had a HR of 2.104 (CI 1.3-3.5; p=0.003) for negative outcome in patients undergoing TAVI, while elevated NTproBNP had HR of 1.412 (CI 0.8-2.4; p=0.212). Moreover, this analysis also revealed the log. ES as an independent risk factor (HR of 2.211, CI 1.3-3.7; p= 0.002). Conclusion: Increased GDF15 levels are associated with a poor prognosis in patients undergoing TAVI. Furthermore, GDF15 showed to be superior to the established biomarker NTproBNP in risk stratification of patients undergoing TAVI providing additional prognostic information.

Abstract Background Aneurysmal subarachnoid hemorrhage (SAH) is a kind of destructive cerebrovascular disease which could affect people's cognition, even the life expectancy. People with SAH are considered in a fatal situation, especially in the young population. This study aimed to investigate cognitive impairment and related factors in young patients with ruptured anterior communicating artery (ACoA) aneurysms.Methods We conducted a multicentre retrospective follow-up study at three hospitals in China. The young patients (18-50 years) who underwent ruptured ACoA aneurysm treatment by microsurgical clipping or endovascular coiling at three academic institutions in China from January 2015 to November 2017 were recruited. Patient cognition and life quality were assessed by using modified Telephone Interview for Cognitive Status (TICS-m), the modified Rankin Scale (mRS), and the instrumental activities of daily living (IADL) scale 2. Multiple cox-regression analysis was used to identify variables independently associated with cognitive impairment.Results Of the total of 59 patients, 54 (91.5%) achieved good clinical outcomes (mRS score 0-2) and 51 (86.4%) had excellent quality of life (IADL score 8). Ten (16.9%) patients showed cognitive impairments (TICS-m<27). The multivariate COX regression analysis showed that mRS scores of 3-5 at discharge, female sex, and aneurysm size <5 mm was independently associated with cognitive impairment. TICS-m scores at the latest follow-up were similar after open surgery and coiling. Conclusion In this relatively young sample that excluded patients with very poor-grade SAH or serious complications, microsurgical clipping led to better clinical outcomes than endovascular coiling, while cognitive outcomes were similar across treatment modalities. These results are not completely consistent with previous studies, and should therefore be considered in the clinical practice as well as further investigated in larger patient samples.

IntroductionPrevious epidemiological studies have reported on the prevalence of diabetic kidney disease (DKD) and diabetic retinopathy (DR) from India. The aim of this study is to evaluate the effect of DKD on the development of new-onset DR and sight-threatening diabetic retinopathy (STDR) in Asian Indians with type 2 diabetes (T2D).Research design and methodsThe study was done on anonymized electronic medical record data of people with T2D who had undergone screening for DR and renal work-up as part of routine follow-up at a tertiary care diabetes center in Chennai, South India. The baseline data retrieved included clinical and biochemical parameters including renal profiles (serum creatinine, estimated glomerular filtration rate (eGFR) and albuminuria). Grading of DR was performed using the modified Early Treatment Diabetic Retinopathy Study grading system. STDR was defined as the presence of proliferative diabetic retinopathy (PDR) and/or diabetic macular edema. DKD was defined by the presence of albuminuria (≥30 µg/mg) and/or reduction in eGFR (<60 mL/min/1.73 m2). Cox regression analysis was used to evaluate the hazard ratio (HR) for DR and STDR.ResultsData of 19 909 individuals with T2D (mean age 59.6±10.2 years, mean duration of diabetes 11.1±12.1 years, 66.1% male) were analyzed. At baseline, DR was present in 7818 individuals (39.3%), of whom 2249 (11.3%) had STDR. During the mean follow-up period of 3.9±1.9 years, 2140 (17.7%) developed new-onset DR and 980 individuals with non-proliferative DR (NPDR) at baseline progressed to STDR. Higher serum creatinine (HR 1.5, 95% CI 1.3 to 1.7; p<0.0001), eGFR <30 mL/min/1.73 m2 (HR 4.9, 95% CI 2.9 to 8.2; p<0.0001) and presence of macroalbuminuria >300 µg/mg (HR 3.0, 95% CI 2.4 to 3.8; p<0.0001) at baseline were associated with increased risk of progression to STDR.ConclusionsDKD at baseline is a risk factor for progression to STDR. Physicians should promptly refer their patients with DKD to ophthalmologists for timely detection and management of STDR.

Abstract Background CHA2DS2-VASc score has been used as a surrogate marker for predicting outcomes beyond thromboembolic risk in patients with atrial fibrillation (AF). Likewise, cardiac troponin I (cTnI) is a predictor of mortality in AF. Purpose This study aimed to investigate the association of cTnI and CHA2DS2-VASc score with long-term prognosis in patients admitted to the emergency department with AF. Methods A retrospective cohort study conducted between January 2012 and December 2013, enrolling patients admitted to the emergency department with AF and having documented cTnI measurements. CHA2DS2-VASc score was estimated. Primary endpoint was 5-year all-cause mortality, readmission for heart failure (HF), readmission for myocardial infarction (MI) and the composite end point of major adverse cardiac events defined as death, readmission for HF or readmission for MI (MACE). Results A total of 578 patients with AF were studied, of whom 252 patients had elevated levels of cTnI (43.6%) and 334 patients had CHA2DS2-VASc score >3 (57.8%). Patients with elevated cTnI tended to be oldercompared with those who did not have cTnI elevation and were more frequently comorbid and of higher ischemic risk, including hypertension, prior MI, prior HF, chronic renal failure and peripheral artery disease. The overall median CHA2DS2-VASc score was higher in those with cTnI elevation compared to those patients elevated cTnI levels (4.2 vs 3.3 points, p<0.001). Main diagnoses at hospital discharge were tachyarrhythmia 30.3%, followed by heart failure 17.7%, respiratory infections 9.5% and acute coronary syndrome 7.3%. At 5-year follow-up, all-cause death was significantly higher for patients with cTnI elevation compared with those who did not have cTnI elevation (56.4% vs. 27%; logrank test p<0.001). Specifically, for readmissions for HF and readmissions for MI there were no differences in between patients with or without cTnI elevation. In addition, MACE was reached in 165 patients (65.5%) with cTnI elevation, compare to 126 patients (38.7%) without cTnI elevation (p<0.001). On multivariable Cox regression analysis, cTnI elevation was an independent predictor of all-cause death (hazard ratio, 1.67, 95% confidence interval [CI]: 1.24–2.26, p=0.001) and of MACE (hazard ratio 1.47, 95% confidence interval 1.15–1.88; P=0.002), but it did not reach statistical significance for readmissions for MI and readmissions for HF. CHA2DS2-VASc score was a predictor on univariate Cox regression analysis for each endpoint, but it did not reach significance on multivariable Cox regression analysis for any endpoint. Conclusions cTnI is independently associated with long-term all-cause mortality in patients attending the emergency department with AF. cTnI compared to CHA2DS2-VASc score is thus a biomarker with predictive capacity for mortality in late follow-up, conferring utility in the risk stratification of patients with atrial fibrillation.
