Obesity increases with age, is disproportionately prevalent in black populations, and is associated with heart failure with preserved ejection fraction (HFpEF). An "obesity paradox," or improved survival with obesity, has been reported in patients with HFpEF. The aim of this study was to examine whether racial differences exist in the temporal trends and outcomes associated with obesity among older patients with HFpEF.

Community surveillance of acute decompensated heart failure (ADHF) hospitalizations, sampled by stratified design from 2005 to 2014.

Atherosclerosis Risk in Communities Study (NC, MS, MD, MN).

A total of 10,147 weighted hospitalizations for ADHF (64% female, 74% white, mean age 77 years), with ejection fraction ≥50%.

ADHF classified by physician review, HFpEF defined by ejection fraction ≥50%. Apatinib solubility dmso Body mass index (BMI) calculated from weight at hospital discharge. Obesity defined by BMI ≥30 kg/m

When aggregated across 2005-2014, the mean BMI wasnts were disproportionately burdened by obesity in this decade-long community surveillance of older hospitalized patients with HFpEF. However, temporal increases in mean BMI and class III obesity prevalence among white patients narrowed the racial difference in recent years. link2 For both races, the worst survival was observed with class III obesity. Effective strategies are needed to manage obesity in patients with HFpEF.Persimmon leaf extracts (PLE) have been widely used as a traditional medicine in East Asian countries. The effects of persimmon leaves, including antioxidant, antiinflammatory, hypotensive, and anti-allergy effects, have been investigated; however, there is little evidence on the inhibition of T cell activation in vitro and effects on T cell-related diseases, such as atopic dermatitis (AD), in vivo by persimmon leaves. PLE (50 μg/mL) effectively attenuated the mRNA levels of IL-2 in Jurkat T cells stimulated with PMA/A23187 and Staphylococcus enterotoxin E-loaded Raji B cells without causing cytotoxicity. In Jurkat T cells stimulated with PMA/A23187, treatment with 50 μg/mL PLE blocked the translocation of p65 and IκBα degradation. Moreover, the JNK signaling pathway in Jurkat T cells stimulated with PMA/A23187 was affected by treatment with PLE. The oral administration of PLE markedly attenuated AD manifestations in mice, including ear thickness, IgE levels, and lymph node sizes. These results indicate PLE significantly blocked T cell activation via NF-κB signaling and the JNK pathway. This suggests underlying mechanisms of PLE involving the control of effector cytokines produced by activated T cells in ear tissue and lymph nodes, as well as the infiltration of mast cells and the therapeutic potential of AD.More recently, there has been a paradigm shift toward selective drug targeting in the treatment of neurological disorders, including drug addiction, schizophrenia, and Parkinson's disease mediated by the different dopamine receptor subtypes. Antagonists with higher selectivity for D3 dopamine receptor (D3DR) over D2 dopamine receptor (D2DR) have been shown to attenuate drug-seeking behavior and associated side effects compared to non-subtype selective antagonists. However, high conservations among constituent residues of both proteins, particularly at the ligand-binding pockets, remain a challenge to therapeutic drug design. Recent studies have reported the discovery of two small-molecules R-VK4-40 and Y-QA31 which substantially inhibited D3DR with >180-fold selectivity over D2DR. Therefore, in this study, we seek to provide molecular and structural insights into these differential binding mechanistic using meta-analytic computational simulation methods. Findings revealed that R-VK4-40 and Y-QA31 adopted shallow binding modes and were more surface-exposed at D3DR while on the contrary, they exhibited deep hydrophobic pocket binding at D2DR. Also, two non-conserved residues; Tyr361.39 and Ser18245.51 were identified in D3DR, based on their crucial roles and contributions to the selective binding of R-VK4-40 and Y-QA31. Importantly, both antagonists exhibited high affinities in complex with D3DR compared to D2DR, while van der Waals energies contributed majorly to their binding and stability. Structural analyses also revealed the distinct stabilizing effects of both compounds on D3DR secondary architecture relative to D2DR. Therefore, findings herein pinpointed the origin and mechanistic of selectivity of the compounds, which may assist in the rational design of potential small molecules of the D2 -like dopamine family receptor subtype with improved potency and selectivity.
During the coronavirus disease 2019 (COVID-19) pandemic, digestive surgery potentially exposes both health-care professionals and vulnerable patients to COVID-19. A survey was conducted with aim to determine the digestive surgery services provided during the COVID-19 pandemic, optimize safety for patients and clinicians, and safeguard health-care services.

An online survey was conceived and circulated to members of the Indonesian Society of Digestive Surgeons. The survey was conducted in two phases, in April 2020 and July 2020, to evaluate changes in response to the COVID-19 pandemic.

Early in the pandemic (April 2020), the median number of major digestive surgeries performed monthly declined from 20 cases (range. 3-100 cases) to 1 case (range. 0-10 cases) (P < .001; Wilcoxon signed-rank test). Most of the cases in April 2020 addressed emergency problems, but more definitive surgeries were performed during the later period of the survey. The importance of screening for COVID-19 with polymerase chain reaction has increased over time, and a more comprehensive screening methodology incorporating real-time polymerase chain reaction, chest CT, and rapid antibody test were evident in 31.37% of July 2020 responses.

Our survey has shown that surgeons adapted to the evolving pandemic and continue to do so only with appropriate safety assurances.

The peculiar immune response triggered by this virus, which seems to last only few months, led to a search for alternatives such as passive immunization in addition to conventional vaccinations. Convalescent sera, monoclonal antibodies selected from the most potent neutralizing binders induced by the virus infection, recombinant human single-domain antibodies, and binders of variable scaffold and different origin have been tested alone or in combination exploiting monovalent, multivalent and multispecific formats. In this review, we analyse the state of the research in this field and present a summary of the ongoing projects finalized to identify suitable molecules for therapies based on passive immunization.Hemostatic unbalance is often observed in patients with coronavirus disease 2019 (COVID-19), and patients with severe disease are at high risk of developing thromboembolic complications. Viscoelastic methods (VEMs), including thrombelastography (TEG) and thromboelastometry (TEM), provide data on the nature of hemostatic disturbance. In this systematic review, we assessed the performance of TEG and TEM in the assessment of blood coagulation and fibrinolysis in patients with COVID-19. PubMed, Scopus, Web of Science Core Collection, medRxiv, and bioRxiv were systematically searched for clinical studies evaluating TEG and/or TEM variables in COVID-19 individuals. Ten studies, with a total of 389 COVID-19 patients, were included, and VEMs were performed in 292 of these patients. Most patients (90%) presented severe COVID-19 and required mechanical ventilation. TEG and TEM variables showed that these patients displayed hypercoagulability and fibrinolysis shutdown, despite the use of appropriate thromboprophylaxis. However, the mechanism underlying these phenomena and their clinical significance in COVID-19 patients who developed thrombosis are still not clear. Further studies are warranted if VEMs might help to identify those at highest risk of thrombotic events and who therefore may derive the greatest benefit from antithrombotic therapy.The effect of anabolic-androgenic steroid (AAS) abuse on the contact activation system (CAS) is not known in detail. We hypothesized that current AAS abuse reduces the kallikrein-generating capacity of CAS significantly and investigated the impact of AAS on the proteins and capacity of CAS in current and former AAS abusers and healthy age-matched controls. Men 18 to 50 years of age were included as current AAS abusers, former AAS abusers, or controls. Blood samples were collected after overnight fasting. Kallikrein generation (lag time, peak height, and endogenous kallikrein potential [EKP]), coagulation factor XII (FXII), prekallikrein, high-molecular-weight kininogen (HK), and Complement C1 esterase inhibitor (C1inh) were assessed. Groups were compared by analysis of variance or Kruskal-Wallis test and probabilities were corrected for multiple comparisons. Associations were evaluated by linear regression models. The EKP was significantly reduced in current (n = 37) AAS abusers (984 ± 328 nmol/L × min) compared with former (n = 33) abusers (1,543 ± 481 nmol/L × min) and controls (n = 30) (1,521 ± 339 nmol/L × min), p  less then  0.001. Current abusers had higher levels of FXII and C1inh and lower levels of prekallikrein and HK than controls, p ≤ 0.025. Stepwise regression analysis showed that EKP was associated with C1inh and prekallikrein in current AAS abusers, R2 = 0.70, p  less then  0.001. We conclude that current AAS abuse reduces the kallikrein-generating capacity of CAS by increasing the concentration of C1inh and reducing the concentration of prekallikrein. These changes may contribute to the anti-inflammatory effect of testosterone.Compared with Caucasian patients, East Asian patients have the unique risk-benefit trade-off and different responsiveness to antithrombotic regimens. The aim of this study was to compare pharmacodynamic profile in East Asian patients with acute coronary syndromes (ACSs) treated with prasugrel standard-dose versus a de-escalation strategy. Before discharge, ACS patients with age less then 75 years or weight ≥60 kg (n = 255) were randomly assigned to the standard-dose (10-mg group) or de-escalation strategy (5-mg group or platelet function test [PFT]-guided group). After 1 month, VerifyNow P2Y12 assay-based platelet reactivity (P2Y12 reaction unit [PRU]) and bleeding episodes were evaluated. Primary endpoint was the percentage of patients with the therapeutic window (85 ≤ PRU ≤ 208). The 250 patients completed 1-month treatment. link3 The percentage of patients within the therapeutic window was significantly lower in the 10-mg group (n = 85) compared with the 5-mg (n = 83) and PFT-guided groups (n = 82) (35.3 vs. 67.
