Three undescribed monoterpenoid indole alkaloid dimers (kopoffines A-C, which are connected via a methylene unit) and with nine known alkaloids were isolated and identified from the fruits of Kopsia arborea Blume. Their structures, including their absolute configurations, were established by HRESIMS, NMR, single-crystal X-ray diffraction, and ECD analyses. Kopoffines A-C showed significant inhibition against cyclin-dependent kinase 5 (IC50 0.34-2.18 μM). Western blotting analyses showed that kopoffines A-C significantly decreased the protein levels of CDK5 and phospho-CDK5 (Tyr15) (pCDK5) at concentrations of 2.5 and 10 μM. The levels of phospho-Tau (Thr217) (pTau217, a new biomarker of AD), and phospho-Tau (Ser396) (pTau396), which play major roles in the formation of neurofibrillary tangles , were decreased by the kopoffines A-C treatment. Molecular docking studies indicated that kopoffines A-C could form stable interactions with CDK5.<br /><br /> The long-term benefit provided by advanced hybrid closed-loop (AHCL) systems needs to be assessed in general populations and specific subpopulations.<br /><br /> A prospective evaluation of subjects initiating the AHCL system 780G was performed. Time in range (70-180mg/dl) (TIR), &lt;70mg/dl, &lt;54mg/dl, &gt;180mg/dl and &gt;250mg/dl were compared, at baseline and after one year, in different subpopulations, according to previous treatment (pump vs MDI), age (&gt; or ≤25years old) and hypoglycaemia risk at baseline.<br /><br /> 135 subjects were included (age 35±15years, 64% females, diabetes duration 21±12years). An increase in TIR was found, from 67.26±11.80% at baseline to 77.41±8.85% after one year (p&lt;0.001). All the subgroups showed a significant improvement in TIR, time&gt;180mg/dl and &gt;250mg/dl. At the 1-year evaluation, no significant differences were found, between previous pump users and MDI subjects. Children and young adults had a lower time&lt;70mg/dl than adults. Subjects with a high risk of hypoglycaemia at baseline had a higher time spent at &lt;70mg/dl and &lt;54mg/dl than low-risk individuals.<br /><br /> The initial benefit provided by the AHCL system is sustained in the long term.

MDI subjects obtain the same outcomes as subjects with pump experience.<br /><br /> To find the incidence, risk factors and predictors of cardiovascular (CV) mortality for aortic stenosis (AS) in patients with type 2 diabetes mellitus (T2DM).<br /><br /> Between 2014 and 2019, 20,979 patients with T2DM who underwent echocardiography were enrolled for analysis. The mean follow-up period was 34months. Multiple risk factors and outcomes for patients with and without AS were presented.<br /><br /> AS was present in 776 (3.70%) patients. Age, female, chronic kidney disease, hyperlipidemia, and peripheral arterial disease statistically increased risk of AS. The CV mortality (adjusted hazard ratio [aHR]=1.97; 95% confidence interval [CI] 1.336 - 2.906, p&lt;0.001) and risk of hospitalization for heart failure (HHF) (aHR=1.73, 95% CI 1.442-2.082, p&lt;0.001) were significantly increased in patients with AS, without significant differences in acute myocardial infarction and stroke. Severity of AS, body mass index (&lt;27kg/m<br /><br /> ), hypertension, hyperuricemia, left ventricular dysfunction (ejection fraction&lt;50%), and hematocrit (&lt;38%) were significantly associated with increased CV mortality and HHF.<br /><br /> AS was associated with an increased risk of CV mortality and HHF in patients with T2DM.<br /><br />AS was associated with an increased risk of CV mortality and HHF in patients with T2DM.<br /><br /> To assess if patients with type 2 diabetes mellitus (DM2) are a) at excess risk of undergoing testing, contracting, and dying from SARS-CoV-2 infection compared to the general population; b) whether cardiovascular diseases (CAVDs) contribute to COVID-19-related death; and c) what is the effect of DM2 duration and control on COVID-19-related death.<br /><br /> This population-based study involved all 449,440 adult residents of the Reggio Emilia province, Italy. DM2 patients were divided in groups by COVID testing, presence of CAVDs and COVID death. Several mediation analyses were performed.<br /><br /> Patients with DM2 had an increased likelihood of being tested (Odds ratio, OR 1.27 95%CI 1.23-1.30), testing positive (OR 1.21 95%CI 1.16-1.26) and dying from COVID-19 (OR 1.75 95%CI 1.54-2.00). COVID-19-related death was almost three times higher among obese vs non-obese patients with DM2 (OR 4.3 vs 1.6, respectively). For COVID-19 death, CAVDs mediated a) just 5.1% of the total effect of DM2, b) 40% of the effect of DM2 duration, and c) did not mediate the effect of glycemic control.<br /><br /> For COVID-19-related deaths in DM2 patients, the effect is mostly direct, obesity amplifies it, DM2 control and duration are important predictors, while CAVDs only slightly mediates it.<br /><br />For COVID-19-related deaths in DM2 patients, the effect is mostly direct, obesity amplifies it, DM2 control and duration are important predictors, while CAVDs only slightly mediates it.<br /><br /> Previous research in non-dialysis patients suggests that the inflammatory skin disease psoriasis is associated with an increased risk of severe vascular events like myocardial infarction (MI). Thus, we determined whether psoriasis represents a significant risk factor for MI in end-stage renal disease (ESRD) patients.<br /><br /> We queried the United States Renal Data System for ESRD patients starting dialysis between 2004 and 2015. ICD-9 and ICD-10 codes were used to identify those with at least two diagnoses of psoriasis, a diagnosis of MI, and other clinical risk factors. Logistic regression was used to examine the association of psoriasis and various risk factors with MI.<br /><br /> Of a cohort of 1,062,693, we identified 6823 (0.6%) subjects with psoriasis and 181,960 (17.1%) with MI. Of the 6823 patients with psoriasis, 1671 (24%) developed an MI. Psoriasis was associated with an increased risk of MI in an unadjusted model [odds ratio (OR) = 1.34; confidence interval (CI) = 1.26-1.42]. However, after controlling for demidities may influence the choice of therapy for psoriasis and outcomes.<br /><br /> Diffuse large B-cell lymphoma (DLBCL) patients have been reported to have cardiac manifestations, however, arrhythmias have not been characterized in this population. We examined the predictors of arrhythmias and assessed the impact of arrhythmias on inpatient outcomes among DLBCL patients.<br /><br /> Retrospective cohort analysis was performed using the National Inpatient Sample data collected between 2016 and 2018. Multivariable logistic and linear regression models were used to examine the predictors of arrhythmias and inpatient outcomes among DLBCL patients.<br /><br /> 11% of DLBCL patients had a diagnosis of arrhythmias. Patients aged 70 years or older had 2.6 times higher odds (95% CI 2.37-2.78) of having arrhythmias compared to patients younger than 70 years. Females were 23% (AOR 0.77; 95% CI 0.71-0.83) less likely to have a diagnosis of arrhythmias relative to their male counterparts. Compared to non-Hispanic whites, patients who were non-Hispanic blacks (AOR 0.69; 95% CI 0.60-0.81), Hispanics (AOR 0.60; 95% CI 0.52-0.69) or in the non-Hispanic other category (AOR 0.80; 95% CI 0.70-0.91) were significantly less likely to be diagnosed with arrhythmias. Other factors that predicted arrhythmias were patient disposition and comorbidity index. Additionally, arrhythmias were associated with higher inpatient mortality, length of stay and hospital costs.<br /><br /> Older male patients were more likely to be diagnosed with arrhythmias while non-Hispanic blacks and Hispanics were less likely to have arrhythmias. These findings highlight the need for surveillance to enable early detection of arrhythmias in this population.<br /><br />Older male patients were more likely to be diagnosed with arrhythmias while non-Hispanic blacks and Hispanics were less likely to have arrhythmias.

It is a rare and fatal complication of antiphospholipid syndrome (APS). We present a rare case of CAPS that presented with bilateral (b/l) adrenal hemorrhage making the diagnosis challenging in this otherwise rare disease. A 51-year-old female was initially admitted with abdominal pain and found to have bilateral adrenal hemorrhage. Patient had a fulminant disease course in which she had thrombotic manifestations involving multiple organ systems. This case was especially challenging as the patient's bilateral adrenal hemorrhage was the first manifestation of CAPS; the diagnosis of APS had to be made while treatment for presumed CAPS was emergently commenced for this life-threatening disease. Key to managing this condition is having a high index of suspicion for the diagnosis in patients presenting with multi-organ failure and multiple thromboses and hemorrhage.l-Rhamnose isomerase (l-RhI) catalyzes rare sugar isomerization between aldoses and ketoses. In an attempt to alter the substrate specificity of Thermoanaerobacterium saccharolyticus NTOU1 l-RhI (TsRhI), residue Ile102 was changed to other polar or charged amino acid residues by site-directed mutagenesis. The results of activity-screening using different substrates indicate that I102N, I102Q, and I102R TsRhIs can increase the preference against d-allose in comparison with the wild-type enzyme. The catalytic efficiencies of the purified I102N, I102Q, and I102R TsRhIs against d-allose are 148 %, 277 %, and 191 %, respectively, of that of wild-type enzyme, while those against l-rhamnose are 100 %, 167 % and 87 %, respectively. Mutant I102N, I102Q, and I102R TsRhIs were noted to have the altered substrate specificity, and I102Q TsRhI has the highest catalytic efficiency against d-allose presumably through the formation of an additional hydrogen bond with d-allose. The purified wild-type and mutant TsRhIs were further used to produce d-allose from 100 g/L d-fructose in the presence of d-allulose 3-epimerase, and the yields can reach as high as 22 % d-allulose and 12 % d-allose upon equilibrium. I102Q TsRhI takes only around half of the time to reach the same 12 % d-allose yield, suggesting that this mutant enzyme has a potential to be applied in d-allose production.<br /><br /> To evaluate the efficacy of physical exercise in improving depressive symptoms in Parkinson disease (PD).<br /><br /> We conducted a systematic review of randomized controlled trials (RCTs) following a prespecified protocol guidance (PROSPERO CRD42021243142). Two independent authors searched for studies in MEDLINE, Cochrane Register of Controlled Trials, Physiotherapy Evidence Database, Embase, PsycINFO, and Sports Discus from database inception to June 2022.<br /><br /> Two independent authors extracted the data and evaluated the risk of bias using the revised Cochrane risk of bias tool. We performed random-effects meta-analyses and rated the certainty of evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach.<br /><br /> A total of 36 RCTs met the inclusion criteria, 14 of which were pooled in the quantitative synthesis. Depression symptomatology significantly decreased in the exercise group compared with usual care (standardized mean difference [SMD], -0.49; 95% confidence interval [CI], -0.
