Heart failure can be caused by various disorders, such as myocardial infarction, hypertension, viral infection, exposure to toxins, chemotherapy, or genetically transmitted muscular diseases. Regardless of the etiology, these disorders initiate ventricular remodeling, an adaptive, compensatory process which becomes progressively maladaptive and the cause of functional and clinical deterioration, eventually leading to heart failure. Local and systemic compensatory responses that initially allow surviving muscle to maintain hemodynamic function continue over time and due to this persistent compensatory over-activity the initially unaffected myocardium becomes dysfunctional. These compensatory responses to an abnormal cardiac load or myocardial injury involve several pathophysiological adaptations in the cardiac structure at the genetic, molecular, cellular, and tissue levels. Furthermore, left ventricular pressure and volume overload has shown to alter metabolic substrate utilization, decrease mitochondrial function and reduce energy production in the failing heart.

Mechanical circulatory support with LVAD has become a standard bridge to cardiac transplantation, and has also been approved in the United States as permanent (destination) therapy for selected patients presenting with end-stage heart failure. Clinical experience with LVAD support has shown that it can reverse the complex process of chronic left ventricular remodeling to a point where a subset of patients could be weaned from the device after restoration of basic cardiac function. LVAD-induced mechanical unloading of the failing heart leads to reduced mitochondrial density, structure and function, and interventions that enhance mitochondrial biogenesis, function and structure, such as controlled cardiac reloading may enhance LVAD-induced myocardial reverse remodeling and cardiac recovery. This study is designed to investigate gradual reduction in LVAD speed within the range defined by the assist device manufacturer's manual as appropriate for regular clinic use, to determine the effect on reverse remodeling and myocardial recovery in end-stage heart failure patients.
PURPOSE:Modified urokinase obtained by bonding chemically a fraction having affinity for fibrin prepared by hydrolyzing human plasminogen to urokinase. CONSTITUTION:Human plasminogen [prepared by linkage product of (H chain peptide)-(L chain peptide) from the side of N end] is hydrolyzed with a proteolytic enzyme (e.g., elastase of swine pancreas), and a fraction having affinity for fibrin(linkage product of K1-K2-K3 having 27,000-39,000mol.wt.) is obtained from the hydrolyzed mixture by fractionation and collection through affinity chromatography using an adsorbent obtained by bonding ligand to lysine and gel filtration. This fraction is chemically bonded to urokinase, to give modified urokinase having high adsorption porperty of fibrin. In the chemical bonding, a crosslinking agent by ionic mechanism such as condensation reaction, addition reaction, etc. is used. It is suitable as a thrombolytic drug.
Varicella zoster virus (VZV) is so well known as the cause of cutaneous varicella (chickenpox) and zoster (shingles) that it can be hard to imagine it as an enteric pathogen. VZV establishes latency during varicella and returns to the skin in zoster when the neurons in which VZV reactivates have cutaneous projections. Because a viremia occurs during varicella, VZV also infects and establishes latency in enteric neurons that do not innervate the skin. VZV can reactivate in enteric neurons to give rise to "enteric zoster", which can occur without an associated rash. Because a rash may thus be absent, pain due to enteric zoster can be occult. The Investigators have found, however, that VZV DNA, which is absent from normal saliva, is detectable in saliva whenever an active (lytic) VZV infection is present in the body; thus, detection of salivary VZV is a non- invasive diagnostic tool that, in combination with enteric signs and symptoms, helps to identify GI disorders that involve VZV. The Investigators have found VZV transcripts and protein in endoscopic biopsies from patients with occult abdominal pain and salivary VZV DNA, which verifies that these patients have enteric zoster. These observations led the Investigators to investigate the potential association between VZV and achalasia in 15 patients.

The Investigators found salivary VZV DNA in 12/15 subjects examined prior to myotomy and, subsequently, VZV transcripts in 13/15 of the resected myotomy specimens. The tissue also contained VZV immunoreactive (gE, gH, ORF40p) neurons, nerve fibers, and multinucleated giant cells. To help determine whether this persistent VZV infection of esophageal neurons is causally related to achalasia, the Investigators now propose to conduct a clinical trial of valacyclovir to determine whether eradication of VZV alleviates achalasia symptoms and improves esophageal function. The Investigators also plan to quantify viral load in relation to achalasia phenotypes and employ next generation sequencing to look for a genetic basis of esophageal VZV reactivation. Finally, because mast cell accumulation and degranulation have been reported in the achalasia esophagus and verified in our preliminary data, the Investigators will test the hypothesis that mast cell activation contributes to manifestations and/or painful symptoms of VZV- associated achalasia. To gain insight into mechanisms of achalasia pathogenesis, the Investigators will also determine whether VZV reactivates specifically in neurons thought to control relaxation of the lower esophageal sphincter (nitric oxide synthase) and/or the excitatory phase of esophageal peristalsis (choline acetyltransferase). Viral destruction of nitrergic inhibitory neurons could be a cause of failure of LES smooth muscle to relax and either or both of these neurons could contribute to the loss of peristalsis that accompanies achalasia.
OBJECTIVES: Pregnancy-related physiological adaptations result in increased heart rate as well as electrocardiographic changes such as a mean QTc prolongation of 27 ms. Pregnant women with CHD are at increased risk for cardiovascular complications. The aim of this study was to identify risk factors for abnormally prolonged QTc interval-a risk factor for ventricular arrhythmias-in pregnant women with CHD.
MATERIAL AND METHOD: Retrospective longitudinal single-centre study. Pre-pregnancy demographic and electrocardiographic risk factors for abnormal QTc duration during pregnancy of (a) > 460 ms and (b) >27 ms increase were analyzed.
RESULTS: Eighty-three pregnancies in 63 women were included, of which three had documented arrhythmias. All five Modified World Health Organization Classification of Maternal Cardiovascular Risk (mWHO) classes were represented, with 15 pregnancies (18.1%) in mWHO class I, 26 (31.3%) in mWHO II, 28 (33.7%) in mWHO II-III, 11 (13.3%) in mWHO III, and three pregnancies (3.6%) in mWHO class IV. Heart rate and QTc interval increased, while QRS duration and PR interval shortened during pregnancy. QTc duration of > 460 ms was associated with increased pre-pregnancy QTc interval, QRS duration, and weight, as well as body mass index. QTc increase of > 27 ms was associated with increased heart rate prior to pregnancy. No significant associations of electrocardiographic changes with mWHO class or CHD type were identified.
CONCLUSION: Increased QTc in pregnant women with CHD was associated with being overweight or having higher heart rate, QRS, or QTc duration prior to pregnancy. These patients should be monitored closely for arrhythmias during pregnancy.

The use of cryotherapy delivered with the trūFreeze® System via noncontact spray ablates the cancer cells while allowing adjacent normal tissue to regenerate. When the liquid nitrogen is delivered to the malignant lesion the cancer cells undergo ablation induced by intracellular water being frozen in place such that ice crystals are formed. These ice crystals aggregate quickly causing immediate intracellular energy producing organelles to be destroyed leading to a non-viable cell. Subsequent tumor sloughing and absorption of apoptotic cells occurs with a subsequent debulking of the tumor mass. Normal tissue will regenerate as re-epithelialization occurs. The extreme cold of -196 degrees Celsius or a "hard freeze" leads to more extensive primary cell death over a shorter freeze time as compared to cryoprobes. A reduction of overall tumor obstruction in the esophageal lumen can reduce symptoms of dysphagia, delay the time until stent is needed, provide palliative care for patients for whom additional tri-modal therapies are not an option, and may increase quality of life in esophageal cancer patients. The studies conducted to date have provided documentation of the safety and effectiveness of spray cryotherapy (SCT) when used for malignancies in the esophagus. Measures of dysphagia relief have been described in peer reviewed literature. This study aims to provide much needed HRQOL information as well as additional tumor characteristics before and after SCT. A cohort of patients with locally persistent esophageal cancer will be studied in up to twelve (12) centers in the United States to provide important HRQOL data and more a comprehensive understanding of clinical tumor response post SCT. In the proposed study, the trūFreeze® System spray cryotherapy procedure will be performed during endoscopy. Each SCT procedure will be performed endoscopically at clinically indicated intervals of 6 weeks +/- 3 weeks. Total procedure dosimetry will be delivered at the discretion of the Investigator based on tumor location and patient tolerability. After each procedure at defined intervals, patients will be contacted and QOL symptom related information will be collected. If at any point an Investigator determines that a subject is not a candidate for further spray cryotherapy or is unable to tolerate additional procedures, they will be contacted via telephone to ascertain HRQOL information. Subject participation will last up to two years or until death

INTRODUCTION: The concurrent occurrence of infectious diseases (IDs) and non-communicable diseases (NCDs) presents complex healthcare challenges in sub-Saharan Africa (SSA), where healthcare systems often grapple with limited resources. While an integrated care approach has been advocated to address these complex challenges, there is a recognised gap in comprehensive evidence regarding the various models of integrated care, their components and the feasibility of their implementation. This scoping review aims to bridge this gap by examining the breadth and nature of evidence on integrated care models for NCDs and IDs within SSA, thereby updating the current evidence base in the domain.
METHODS AND ANALYSIS: Based on the Joanna Briggs Institute (JBI) framework for scoping reviews, this study will include peer-reviewed and grey literature reporting on integrated care models for NCD-ID comorbidities in SSA. A comprehensive search of published sources in electronic databases (PubMed, Scopus, Embase, the Cochrane Library, Health System Evidence and Research4Life) and grey literature (Google Scholar, EBSCO Open Dissertations and relevant organisational websites) will be conducted to identify sources of information reported in English from 2018 onwards. The review will consider sources of evidence reporting on integrated care model for NCDs such as diabetes; chronic cardiovascular, respiratory and kidney diseases; cancers; epilepsy; and mental illness, and comorbid IDs such as HIV, tuberculosis and malaria. All sources of evidence will be considered irrespective of the study designs or methods used. The review will exclude sources that solely focus on the differentiated or patient-centred care delivery approach, and that focus on other conditions, populations or settings. The reviewers will independently screen the sources for eligibility and extract data using a JBI-adapted data tool on the Parsifal review platform. Data will be analysed using descriptive and thematic analyses and results will be presented in tables, figures, diagrams and a narrative summary.
ETHICS AND DISSEMINATION: Ethical approval is not required for this review as it will synthesise published data and does not involve human participants. The final report will be submitted for publication in a peer-reviewed journal. The findings will be used to inform future research.

AIM: Our study aimed to investigate whether BMSCs-derived exosomal miR-381 promotes Treg cell differentiation in lung ischemia-reperfusion injury (LIRI), and the underlying mechanism.
METHODS: The in vitro and in vivo models of LIRI were established by hypoxia/reoxygenation (H/R) treatment and lung ischemia/reperfusion (I/R) surgery, respectively. BMSCs-derived exosomes were isolated and identified by western blot, nanoparticle tracking analysis, and transmission electron microscopy. Cell viability, proliferation, and apoptosis were assessed by CCK-8, EdU, and flow cytometry assay, respectively. IL-18 secretion level in lung microvascular endothelial cells (LMECs) and lung tissue homogenate was examined by ELISA. Treg cell differentiation was determined using flow cytometry. The relationships between miR-381, YTHDF1, and IL-18 were investigated using dual-luciferase reporter gene, RIP, and/or RNA pull-down assays. MeRIP assay was employed to determine m6A modification of IL-18 mRNA in LMECs. The ubiquitination level of Foxp3 protein in CD4+ T cells was analyzed by Co-IP assay.
RESULTS: BMSCs-derived exosomes reduced LMECs injury and increased Treg cell differentiation in LIRI, whereas miR-381 inhibition in BMSCs weakened these impacts. Mechanistically, miR-381 inhibited IL-18 translation in LMECs by inhibiting YTHDF1 expression via binding to its 3'-UTR. As expected, YTHDF1 overexpression in LMECs abolished the effects of miR-381-overexpressed exosomes on LMECs injury and Treg cell differentiation. Moreover, LMECs-secreted IL-18 inhibited Treg cell differentiation by promoting the ubiquitination degradation of Foxp3 protein.
CONCLUSION: BMSCs-derived exosomal miR-381 suppressed IL-18 translation in LMECs through binding to YTHDF1 3'-UTR, thus suppressing the ubiquitination degradation of Foxp3 in CD4+ T cells, which promoted Treg cell differentiation and mitigated LIRI development.

They can be labelled with a dye or fluorescent cpd. incorporated by polymerisation. (A) are useful as carriers for biologically or immunologically active substances (B) to form diagnostic reagents. Suitable (B) are peptides, proteins, enzymes, hormones, vitamins, antigens, antibodies or microorganisms, specifically thyroxin or human-thyreotropin antibodies. (A) bind (B) covalently (not just by adsorption) without affecting their biological activity, and do not bond nonspecifically to other serum proteins. No surfactants, which can alter protein structures, are used in the prodn., suspensions of (A) are not broken during centrifuging and the particles are easily redispersed.
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have been used to reduce glucose levels in patients with type 2 diabetes mellitus since 2005. This meta-analysis discusses the mechanisms and potential benefits of several GLP-1 RAs. In particular, this meta-analysis focuses on the safety and associations with weight loss, glucose reduction, cardiovascular outcomes, heart failure, and renal outcomes of GLP-1 RAs to determine their benefits for patients with different conditions. In terms of glycemic control and weight loss, semaglutide was statistically superior to other GLP-1 RAs. In terms of cardiovascular outcomes, 14 mg of semaglutide taken orally once daily and 1.8 mg of liraglutide injected once daily reduced the incidence of cardiovascular death, whereas other GLP-1 RAs did not provide similar benefits. Moreover, semaglutide was associated with superior outcomes for heart failure and cardiovascular death in non-diabetic obesity patients, whereas liraglutide worsened heart failure outcomes in diabetic patients with a reduced ejection fraction. Additionally, semaglutide, dulaglutide, and liraglutide were beneficial in terms of composite renal outcomes: These GLP-1 RAs were significantly associated with less new or persistent macroalbuminuria, but not with improved eGFR deterioration or reduced requirement for renal replacement therapy. However, GLP-1 RAs may benefit patients with type 2 diabetes mellitus or obesity.
An active substance which retards the development of sex is extracted from animal or human fluids, such as blood, lymph, serum, urine, by processes of concentration and purification controlled by tests on experimental animals.  The substance differs from known hormones such as that obtained from the anterior tube of the hypophysis which have an indirect retarding action on parts of the sex functions due to the formation of lipoid substances in the ovary.  Accordingly, the hypophysis and the corpus luteum, in which their specific hormones predominate, are not suitable sources of the new hormone, and the tests used in controlling the extraction, such as the effect on the rut of female rodents, or on the development of puberty in both sexes must show a real direct retardation of the sexual functions not accompanied by phenomena such as the formation of the corpora lutea in the ovary or hypertrophy of the mucous membrane of the uterus.  In making the extract, concentration of the active substance may be effected by removal of protein, by ultra-filtration or dialysis, by extraction with organic solvents, and by precipitation.  In one example, calves' blood was centrifuged and a mouse test showed greater concentration of the hormone in the liquid portion; this portion was passed through an ultra-filter and tests showed greater concentration in the filtrate, which was worked up by concentration and filtration.  In a second example, young pigs' serum was evaporated to dryness, powdered, extracted with alcohol, and the residue worked up by dialysis of an aqueous extract.  The active substance is present in the dialysate, and was precipitated with methyl alcohol, and the filter residue extracted with water.  In a third example, urine of healthy children was concentrated and filtered and the active substance obtained from the filtrate by precipitating with ethyl alcohol, and submitting an aqueous extract of the filter residue to dialysis.
This is a randomized, multi-center, single dose, double-blind, placebo controlled phase III study of the efficacy and safety of once-per-cycle of F-627 in women with stage II-IV breast cancer who are receiving myelotoxic TA chemotherapy treatment (Taxotere (docetaxel) + Adriamycin(doxorubicin)). F-627 is designed to treat neutropenia, an abnormally low number of neutrophils (a type of white blood cell) in the blood. Neutropenia is often seen in cancer patients receiving myelotoxic chemotherapy.

The primary objective of this study is to evaluate the efficacy and safety of single fixed dose of F-627 in breast cancer patients experiencing myelotoxic chemotherapy in comparison to placebo. F-627 or placebo is to be administered subcutaneously 24 hours after chemotherapy in each 21-day cycle of chemotherapy treatment (up to 4 cycles). Patients randomized to placebo arm will receive F-627 except in cycle 1. The primary endpoint will be the duration of grade 4 (severe) neutropenia - the number of days in which the patient has had an absolute neutrophil count (ANC \< 0.5 x 10\^9/L) observed in chemotherapy cycle 1.
The assistant surgeon or nurse places heel of the hand or fist over the abdominal aorta immediately after the baby is born while the surgeon helps the baby out, the placenta is expulsed or fetched, and the surgeon gains control over bleeding. The compression should be held until controlled bleedning, for example until the first layer of the uterine incision is sutured. Maximum time of aortic compression is 20 minutes, then a 5 minute break is required, after which compression may be reapplied.
