Inflammation is a key determinant of cardiovascular outcomes, but its role in heart failure is uncertain. In patients with cardiometabolic disease enrolled in the prospective, multicenter ancillary study of CIRT (Cardiovascular Inflammation Reduction Trial), CIRT-CFR (Coronary Flow Reserve to Assess Cardiovascular Inflammation), impaired coronary flow reserve was independently associated with increased inflammation and myocardial strain despite well-controlled lipid, glycemic, and hemodynamic profiles. Inflammation modified the relationship between CFR and myocardial strain, disrupting the association between cardiac blood flow and function. Future studies are needed to investigate whether an early inflammation-mediated reduction in CFR capturing microvascular ischemia may lead to heart failure in patients with cardiometabolic disease.

UNASSIGNED: Radical prostatectomy, a standard management approach for localized Prostate Cancer (PC), may cause a stress response associated with immune modulating effects. Regional anesthesia was hypothesized to reduce the immune effects of surgery by minimizing the neuroendocrine surgical stress response, thus mitigating tumor cells dissemination. Our primary objective was to investigate whether the use of spinal blocks attenuates PC tumor cells dissemination on an animal model. We also assessed the number of circulating NK cells and the amount of inflammatory and anti-inflammatory cytokines.
UNASSIGNED: A subcutaneous tumor model, with PC-3M cell line transfected with a luciferase-producing gene (PC-3M-luc-C6) was used. After proper tumor establishment and before tumors became metastatic, animals were submitted to tumor excision surgeries under general or combined (general and spinal) anesthesia. A control group was only anesthetized with general anesthesia.
UNASSIGNED: The subcutaneous tumor model with PC-3M-luc-C6 cells was effective in causing distant metastasis after 35 days. The number of circulating tumor cells increased in animals that underwent surgery under general anesthesia alone compared to the group submitted to combined anesthesia. Interleukin 6 levels were different in all groups, with increase in the general anesthesia group.
UNASSIGNED: Our results suggest that combination of spinal and general anesthesia may attenuate the suppression of innate tumor immunity and it might be related to a reduction in the neuroendocrine response to surgery.

BACKGROUND: Haematopoietic stem cell (HSC) infusion has demonstrated short-term improvement in liver functions in patients with chronic liver disease. The combination of HSC with mesenchymal stem cells (MSCs), which has an immunomodulatory effect, may augment the effects and enhance the duration of improvements on liver functions. The aim of the present study was to assess the safety of infusing the combination of autologous HSCs and MSCs in decompensated liver cirrhosis.
METHODS: In phase I of the study, in vitro assessment was performed to observe the effect of coculturing MSCs with HSCs on their viability and cytokine profiles. Phase II of the study was to assess the safety of combination of stem cell infusions. Bone marrow (50 ml) was aspirated for MSC isolation and expansion using standard protocol. Patients received subcutaneous doses (n = 5) of granulocyte colony-stimulating factor (G-CSF) for stem cell mobilization followed by leukapheresis for harvesting HSCs using CliniMacs. HSCs and MSCs were infused through the hepatic artery under fluoroscopic guidance and were monitored for any adverse effects.
RESULTS: In vitro studies revealed 94% viable HSCs in coculture similar to monoculture. HSCs released only interleukin (IL)-8, whereas MSCs secreted IL-8 and IL-6 in monocultures, and both IL-8 and IL-6 were secreted in coculture. G-CSF administration- and bone marrow aspiration-related complications were not observed. Infusion of the cells through the hepatic artery was safe, and no postprocedural complications were noted.
CONCLUSIONS: The combination of autologous HSC and MSC infusion is a safe procedure in patients with decompensated liver cirrhosis, and the outcomes needed to be assessed in larger studies.
BACKGROUND: NCT04243681.

BACKGROUND: The latest novel corona virus disease (COVID-19) pandemic shows a significant health concern. We aimed to study the prevalence of gastrointestinal symptoms among COVID-19 Egyptian patients.
METHODS: A cross-sectional study was carried out on 860 patients with COVID-19 infection classified according to Ministry of Health Program (MOHP) into three groups (280 patients with mild infection, 258 patients with moderate disease and 322 patients with severe disease). All patients were subjected to medical history, clinical examination, laboratory investigations, high-resolution computed tomography chest (HRCT chest) and other investigations when needed in some patients e.g., upper gastro-intestinal (GI) endoscopy, abdomino-pelvic ultrasound and ECHO.
RESULTS: Gastro-intestinal symptoms were present in 27.2% of the studied patients. The most common reported GIT symptoms were vomiting, diarrhea, abdominal/gastric pain, followed by nausea. GIT symptoms presence was significantly higher in severe cases in comparison to mild or moderate cases. C-reactive protein (CRP), serum ferritin, Aspartate aminotransferase (AST), bilirubin, and creatinine were significantly associated with the presence of GI symptoms.
CONCLUSIONS: GI symptoms are prevalent among COVID-19 patients, the most common were vomiting and diarrhea and were associated with COVID-19 severity.

BACKGROUND: There is an incomplete understanding of the risk of COVID-19 infection in atopic dermatitis (AD) patients.
OBJECTIVE: To evaluate the risk of COVID-19 infection in AD patients in a large, diverse cohort.
METHODS: A case-control study of the All of Us cohort to analyze the association between AD and COVID-19. Comorbidities and risk factors were compared between cases and controls using multivariable analyses.
RESULTS: In a cohort of 11,752 AD cases with 47,008 matched controls, AD patients were more likely to have a COVID-19 diagnosis (4.2% vs 2.8%, P < .001). AD remained significantly associated with COVID-19 in multivariable analysis (odds ratio, 1.29; P < .001) after adjusting for demographic factors and comorbidities.
CONCLUSIONS: Ascertainment of AD and COVID-19 cases using electronic health records and lack of clinical data on AD severity or therapy and COVID-19 outcomes.
CONCLUSIONS: AD is associated with increased odds of COVID-19 infection even after controlling for common comorbidities.

COVID-19 is characterized by vascular inflammation and thrombosis, including elevations in P-selectin, a mediator of inflammation released by endothelial cells. We tested the effect of P-selectin inhibition on biomarkers of thrombosis and inflammation in patients with COVID-19. Hospitalized patients with moderate COVID-19 were randomly assigned to receive either placebo or crizanlizumab, a P-selectin inhibitor, in a double-blind fashion. Crizanlizumab reduced P-selectin levels by 89%. Crizanlizumab increased D-dimer levels by 77% and decreased prothrombin fragment. There were no significant differences between crizanlizumab and placebo for clinical endpoints. Crizanlizumab was well tolerated. Crizanlizumab may induce thrombolysis in the setting of COVID-19.

UNASSIGNED: In schizophrenia, impaired psychomotor speed is a common symptom predicting worse functional outcome. Inflammation causes changes in white matter integrity, which may lead to reduced psychomotor speed. Therefore, we wanted to investigate if peripheral inflammation assessed with cytokines affected performance on psychomotor speed in patients with a spectrum of psychotic disorders.
UNASSIGNED: The current study is a prospective cohort study, including participants from a pragmatic, randomised controlled trial comparing three atypical antipsychotics in patients with a spectrum of psychotic disorders. For the purposes of this sub-study, we analysed drug treatment groups collectively. Psychomotor speed was assessed at baseline, and at weeks 6, 12, 26 and 52 of follow-up, using the neuropsychological tests trail making test (TMT) A and B, and symbol coding. Serum concentration of the following cytokines were measured: interleukin (IL)-β, IL-2, IL-4, IL-6, IL-10, IL12 p70, IL-17a, interferon (IFN)-γ and tumor necrosis factor (TNF)-α. Blood samples were collected at baseline and after 1, 3, 6, 12, 26, 39 and 52 weeks. We analysed the effect of cytokines levels on psychomotor speed over time in linear mixed effects models.
UNASSIGNED: In our linear mixed effects models controlling for possible confounders, IFN-γ had a significant negative effect on TMT-A and symbol coding performance. None of the other tests for psychomotor speed were significantly associated with cytokines. Overall psychomotor speed performance increased significantly across the study period while cytokine levels remained stable.
UNASSIGNED: Our study indicates a negative association between IFN-γ and psychomotor speed, which might be of importance when understanding the mechanisms behind psychomotor deviations in psychotic disorders.

Asthma as chronic airway disease has high prevalence in children and imbalance of Th1/Th2 is a critical mechanism in pathogenesis of the asthma. Baicalein as a cell protective and anti-inflammatory flavonoid may have anti-asthma effect. Therefore, for better using lung, baicalein was used in chitosan-nanoparticle as anti-asthma treatment. Baicalein was loaded and encapsulated in chitosan nanoparticle. The morphology, physical characters (particle size, zeta potential and FT-IR) were analyzed. Drug encapsulation and loading capacity, accumulative release-time were studied. After asthma model producing, the mice were treated with L-B-NP and E-B-NP. At least, MCh challenge test, Cytokines measurement and Lung Histopathology were done. Nanoparticles had average size 285 ± 25 nm with negative charge -2.5 mV. The L-B-NP decreased penh value and E-B-NP decreased inflammation. Both nanoparticles increased IL-12 and decreased IL-5. Also, L-B-NP decreased mucus secretion in bronchi. L-B-NP and E-B-NP control immune-allergo-inflammatory response of asthma. L-B-NP controlled AHR and E-B-NP controlled inflammation that can be used as controlling anti-asthma drug.

Severe respiratory syncytial virus (RSV) bronchiolitis in early life is a significant risk factor for future recurrent wheeze (RW) and asthma. The goal of the Azithromycin to Prevent Wheezing following severe RSV bronchiolitis II (APW-RSV II) clinical trial is to evaluate if azithromycin treatment in infants hospitalized with RSV bronchiolitis reduces the occurrence of RW during the preschool years. The APW-RSV II clinical trial is a double-blind, placebo-controlled, parallel-group, randomized trial, including otherwise healthy participants, ages 30 days-18 months, who are hospitalized due to RSV bronchiolitis. The study includes an active randomized treatment phase with azithromycin or placebo for 2 weeks, and an observational phase of 18-48 months. Two hundred participants were enrolled during three consecutive RSV seasons beginning in the fall of 2016 and were randomized to receive oral azithromycin 10 mg/kg/day for 7 days followed by 5 mg/kg/day for an additional 7 days, or matched placebo. The study hypothesis is that in infants hospitalized with RSV bronchiolitis, the addition of azithromycin therapy to routine bronchiolitis care would reduce the likelihood of developing post-RSV recurrent wheeze (≥3 episodes). The primary clinical outcome is the occurrence of a third episode of wheezing, which is evaluated every other month by phone questionnaires and during yearly in-person visits. A secondary objective of the APW-RSV II clinical trial is to examine how azithromycin therapy changes the upper airway microbiome composition, and to determine if these changes are related to the occurrence of post-RSV RW. Microbiome composition is characterized in nasal wash samples obtained before and after the study treatments. This clinical trial may identify the first effective intervention applied during severe RSV bronchiolitis to reduce the risk of post-RSV RW and ultimately asthma.

UNASSIGNED: Galectin-1 is a recently discovered adipokine that increases with obesity and increased energy intake in adipose tissue. Our aim was to assess whether serum galectin-1 is associated with type 2 diabetes (T2D) and other parameters of the metabolic syndrome independently of body mass index (BMI) in a cohort from the general population.
UNASSIGNED: In this cross-sectional population-based cohort study from the western part of Sweden, we investigated associations between serum galectin-1, clinical characteristics and inflammatory markers in 989 women and men aged 50-65 years [part of the Swedish CArdioPulmonary bioImage Study (SCAPIS) pilot cohort].
UNASSIGNED: We showed in linear models that serum galectin-1 was independently and: (1) inversely associated with T2D (p < 0.05) and glucose (p < 0.05); and (2) positively associated with age (p < 0.01), sex (p < 0.01), BMI (p < 0.01), insulin (p < 0.01) and C-reactive protein (p < 0.01). Furthermore, galectin-1 demonstrated univariate correlations with triglycerides (r = 0.20, p < 0.01), homeostasis model assessment for insulin resistance (r = 0.24, p < 0.01), tumor necrosis factor-α (r = 0.24, p < 0.01), interleukin-6 (IL-6; r = 0.20, p < 0.01) and HbA1c (r = 0.14, p < 0.01).
UNASSIGNED: In a cross-sectional study of a middle-aged population, we showed that serum galectin-1 is: (1) inversely associated with T2D independently of BMI; and (2) independently associated with other markers of the metabolic syndrome These results warrant prospective and functional studies on the role of galectin-1 in T2D.
