BACKGROUND: Pressure offloading is a critical component of plantar foot ulcer management, including diabetes-related foot ulcers (DFU). Conventional offloading options such as total contact casting and removable knee-high walkers may be unsuitable or unsuccessful in patients with morbid obesity, intermittent lower limb oedema, high exudative wounds or poor mobility. A mouldable fibreglass backslab device (BSD) may be a practical alternative to be considered in these situations.
METHODS: Data were retrospectively collected on 28 patients (29 foot ulcers) with non-healing ulcers who received a BSD to offload their foot ulcer as an extension to standard offloading care. Baseline data included: patient demographics, type of offloading prior to BSD application, date of ulcer onset, days ulcer present prior to BSD application and ulcer size at BSD initiation. Measures of success included ulcer size reduction 12 weeks post-BSD application, time to complete ulcer healing in BSD, time to 50% reduction in ulcer size post-BSD application and total number of days ulcer present.
RESULTS: The median (IQR) ulcer area and ulcer duration at baseline for 19 patients (20 ulcers) who used the BSD was 1.65 (0.4-3.8) cm2 and 531 (101-635) days. At 12 weeks, the median (IQR) ulcer area was 0.3 (0-0.55) cm2 with a median (IQR) reduction of 97 (80-100) %. Nine (45%) ulcers achieved complete wound healing (100% reduction in wound size) at 12 weeks post-BSD application, and the remaining 11 (55%) ulcers achieved at least 50% reduction in wound size. The median (IQR) time to complete wound healing and 50% reduction in wound size was 71 (35-134) days and 24 (15-44) days, respectively. Nine patients ceased use of the BSD and reverted to conventional offloading before their wounds had healed. Of these, four patients achieved a 50% reduction in wound size at the 12-week mark with conventional offloading.
CONCLUSION: Our preliminary data suggests that a mouldable fibreglass BSD may be a practical offloading option in the management of DFUs, especially when conventional offloading methods are unsuccessful, unsuitable or unacceptable to patients. Higher level evidence is required to demonstrate suitability or efficacy of the BSD compared to current evidence-based recommended offloading methods.
There are two main types of stomach cancer based on the appearance under the microscope: intestinal-type and diffuse-type. Some stomach cancers also have a mix of intestinal-type and diffuse-type (mixed type). The participants are being invited to take part in this research study due to having been diagnosed with stomach cancer that has spread to other parts of the body and/or cannot be surgically removed, has diffuse-type or mixed type cells or has gene changes that are associated with diffuse-type stomach cancers (such as mutations in the genes called CDH1 or RHOA), and have already been treated with chemotherapy and the disease is now growing. Defactinib is an oral drug that inhibits the protein focal adhesion kinase (FAK), which has been shown to promote growth of gastric cancer. Avutometinib (also known as VS-6766) is an oral drug that blocks an important signaling pathway in cancer cells known as the MAP kinase pathway. Avutometinib inhibits two proteins in the MAPK kinase pathway, RAF and MEK. The purpose of this study is to determine if the combination study treatment with defactinib and avutometinib is effective in improving the length of time after the start of treatment in which a participant is alive and their cancer does not grow or spread.
Thiazide diuretics when used in the treatment of hypertension are associated with many metabolic side effects, including hyperuricemia, gout, insulin resistance, and hyperlipidemia. Each of these conditions is already highly prevalent in African Americans. Our hypothesis is that thiazide-induced hyperuricemia decreases the efficacy of thiazides in controlling BP, leads to endothelial dysfunction, and increases the incidence of insulin resistance and impaired glucose tolerance. This hypothesis will be tested in a randomized, double-blind, placebo-controlled clinical trial of 8-10 weeks duration in which a total of 100 African American patients with hypertension will be enrolled, randomized, and treated as follows:

1. Subjects with untreated stage I hypertension will receive chlorthalidone (25 mg/day) and potassium chloride (40 mEq/day) for 4 weeks. Serum potassium levels will be obtained after four weeks on chlorthalidone. If the level is below 3.5 mEg/L, a bolus of 40 mEq potassium 2 to 3 times daily will be given for 2 to 3 days, or as clinically indicated. A maintenance dose of 50 mEq will be initiated. After at least 7 days, they will then be randomized to add-on allopurinol (300 mg/day) or placebo. Treatment will continue for 8-10 weeks with the chlorthalidone, potassium chloride, and allopurinol/placebo regimen.
2. Subjects with hypertension controlled (i.e. BP \<140/90) or no higher than stage 1 hypertension (i.e., \<160/100) on a single antihypertensive agent or two antihypertensive agents will be switched from their prior antihypertensive agent to chlorthalidone 25 mg/day, and potassium chloride (40mEq/day) for 4 weeks. Serum potassium levels will be obtained after four weeks on chlorthalidone. If the level is below 3.5 mEg/L, a bolus of 40 mEq potassium 2 to 3 times daily will be given for 2 to 3 days, or as clinically indicated. A maintenance dose of 50 mEq will be initiated. After at least 7 days, they will then be randomized to add-on allopurinol (300 mg/day) or placebo. Treatment will continue for 8-10 weeks with the chlorthalidone, potassium chloride, and allopurinol/placebo regimen.

The allopurinol (or placebo) dose will be adjusted to achieve serum uric acid levels between 4 and 5.5 mg/dL after 2 weeks on drug. All subjects will receive a low-sodium diet. The primary endpoint is reduction in systolic BP. Secondary endpoints measure endothelial function, ambulatory blood pressure, body composition, systemic inflammation, metabolic parameters, oxidant stress, and renal hemodynamics.

In SSc, RP is present in 95% of the patients. Despite cold avoidance, RP attacks are severe, painful, affecting the quality of life, with frequent severe ischemic symptoms such as digital ulcers. Treating patients with RP secondary to SSc is extremely challenging. Oral calcium channel blockers, the most commonly prescribed drugs, were shown to be minimally effective in reducing frequency and severity of RP attacks. There is limited evidence for the efficacy of alpha-1-adrenergic receptor antagonists, angiotensin receptor blockers, phosphodiesterase inhibitors and endothelin-1 receptor antagonists to treat RP. The intravenously administered prostacyclin analogue iloprost is considered a second-line therapy, after oral calcium channel blockers, but its administration requires a 5-days hospitalisation for progressive increase in dosage and close blood pressure monitoring. Side effects are almost constant: headache, flushing, malaise and hypotension. Between 2004 and 2015, a total of 145 patients underwent botulinum toxin-A (BTX-A) injections to treat RP in case reports, retrospective or open studies. Since 2016, only 1 randomized, controlled study was performed, including 40 patients but was underpowered, not designed for clinical outcomes, and treated the patient only in one hand. Symptomatic patients treated by BTX-A experienced, in the 3 to 6 following months, pain relief in 75-100% of the cases, as well as reduction in severity and frequency of attacks and increased ulcer healing rate, with minimal adverse effects. The most common complication was temporary hand weakness, related to the injected dose. When the total dose/hand was 50 UI or lower, the rate of hand weakness was 0 to 9%. The proposed study is the first randomized double blinded multicenter clinical trial designed to assess whether or not a single injection schedule of BTX-A in both hands improves RP secondary to SSc better than a placebo at 4, 12 and 24 weeks after the treatment.
BACKGROUND: Pulmonary hypertension (PH) is a common complication of systemic sclerosis (SSc) and a leading cause of mortality among patients with this disease. PH can also occur as an idiopathic condition (idiopathic pulmonary arterial hypertension). Investigation of transcriptomic alterations in vascular populations is critical to elucidating cellular mechanisms underlying pathobiology of SSc-associated and idiopathic PH.
METHODS: We analyzed single-cell RNA sequencing profiles of endothelial and perivascular mesenchymal populations from explanted lung tissue of patients with SSc-associated PH (n=16), idiopathic pulmonary arterial hypertension (n=3), and healthy controls (n=15). Findings were validated by immunofluorescence staining of explanted human lung tissue.
RESULTS: Three disease-associated endothelial populations emerged. Two angiogenic endothelial cell (EC) subtypes markedly expanded in SSc-associated PH lungs: tip ECs expressing canonical tip markers PGF and APLN and phalanx ECs expressing genes associated with vascular development, endothelial barrier integrity, and Notch signaling. Gene regulatory network analysis suggested enrichment of Smad1 (SMAD family member 1) and PPAR-γ (peroxisome proliferator-activated receptor-γ) regulon activities in these 2 populations, respectively. Mapping of potential ligand-receptor interactions highlighted Notch, apelin-APJ (apelin receptor), and angiopoietin-Tie (tyrosine kinase with immunoglobulin-like and EGF-like domains 1) signaling pathways between angiogenic ECs and perivascular cells. Transitional cells, expressing both endothelial and pericyte/smooth muscle cell markers, provided evidence for the presence of endothelial-to-mesenchymal transition. Transcriptional programs associated with arterial endothelial dysfunction implicated VEGF-A (vascular endothelial growth factor-A), TGF-β1 (transforming growth factor beta-1), angiotensin, and TNFSF12 (tumor necrosis factor ligand superfamily member 12)/TWEAK (TNF-related weak inducer of apoptosis) in the injury/remodeling phenotype of PH arterial ECs.
CONCLUSIONS: These data provide high-resolution insights into the complexity and plasticity of the pulmonary endothelium in SSc-associated PH and idiopathic pulmonary arterial hypertension and provide direct molecular insights into soluble mediators and transcription factors driving PH vasculopathy.
Enroll subjects with a normal ejection fraction referred to the catheterization laboratory for evaluation of breathlessness or shortness of breath. Perform safety lab sampling, echocardiography, arterial tonometry for pulse wave analysis, and assessment of endothelial function prior to administration of study drug. During the catheterization researchers will perform blood draws, assess baseline exercise capacity at rest and during exercise. Researchers will also do an echocardiogram to take measurements of the heart. Subjects will be randomized to one of two groups, Oral Myeloperoxidase Inhibitor or placebo group. Study drug or placebo will be administered followed by a repeat of the baseline catheterization assessments. At the conclusion of the second exercise test the subject will be moved to a room and monitored overnight for safety. Repeat blood draws, echocardiogram, endothelial function test, and heart monitoring will be completed. The subject will be asked to follow up with the researchers between 9-14 days after the study drug dosage. The subjects history and blood work will be completed at that visit.

BACKGROUND: Sarcopenia represents a constant threat to the health of older adults, and accurate risk perception is essential for disease prevention and control. However, current methodologies lack rigorously validated instruments to assess the perceived risk of sarcopenia among this group. Thus, this study aimed to develop and validate a sarcopenia disease risk perception scale for older adults.
DESIGN: The study was conducted in two phases: development of the initial scale and its psychometric evaluation. A STROBE checklist was employed.
METHODS: Based on the two-factor model of risk perception theory and the health belief model, the initial draft of the scale was created through literature review, expert consultations, and a preliminary survey with a small sample. Then, we used a cross-sectional study methodology to conveniently select 438 Chinese older adults. Item analysis, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) were used to refine and validate the scale items. Internal consistency and external consistency were assessed to confirm the scale's reliability.
RESULTS: These evaluations established the scale's framework: content validity, item analysis, and EFA. The two factors extracted from the initial analysis explained 62.250% of the observation variance. The CFA confirmed a good fit for the model, demonstrating the scale's robust reliability and validity. The finalized scale includes 15 items and two dimensions: perceived susceptibility (eight items) and perceived severity (seven items).
CONCLUSION: The Sarcopenia Disease Risk Perception Scale for Older Adults is reliable and valid, making it appropriate for assessing the risk perception level in the target population.
Patients will receive Pegasys ® (peginterferon alfa-2a 40kDa) at a dose of 180 micrograms, subcutaneously, once a week, associated with ribavirin at a dose 1000-1250 mg,daily. For genotype 1 treatment time is 48 to 72 weeks and for genotypes 2 and 3, 24 weeks.
BACKGROUND: Tocilizumab improves myocardial salvage in ST-elevation myocardial infarction (STEMI) patients when administered before percutaneous coronary intervention (PCI). The mechanisms underlying ischemia-reperfusion injury remain unclear. In this sub-study, we investigated whether endothelial and platelet-derived CXC chemokines are involved, as they represent inflammatory mediators from two cell types relevant to myocardial infarction. Associations between these chemokines and neutrophils, C-reactive protein (CRP), troponin T (TnT), myocardial salvage index (MSI), microvascular obstruction (MVO), and infarct size.
METHODS: This is a sub-study of the ASSAIL-MI trial, a double-blind clinical trial that randomized 199 STEMI patients to receive either 280 mg tocilizumab (n = 101) or placebo (n = 98) intravenously before PCI. Blood samples were collected prior to infusion, at day 1-2, 3-7, and at 3 and 6 months. Heparin was administered before baseline in 150 patients, while 49 received it after. We measured CXC-chemokines CXCL4, CXCL5, CXCL6, CXCL7, and CXCL12 using immunoassays. Cardiac MRI was performed in the first week and at 6 months.
RESULTS: Tocilizumab did not significantly affect CXC-chemokines levels. Although some correlations were observed between chemokine levels and neutrophil counts and CRP, none of the CXC chemokines were associated with infarct size, MSI, MVO, or TnT levels. Notably, CXCL 12 levels increased in patients who received heparin before baseline, while other CXC-chemokines decreased significantly.
CONCLUSION: This study suggests that the beneficial effects of tocilizumab in STEMI patients are not due to changes in circulating endothelial or platelet-derived CXC-chemokines, compared to placebo. However, heparin significantly influences the levels of these chemokines.

The ALECSAT CBMP will be administered as single dose at week 4, 7 and week 10 which is considered an appropriate time for ALECSAT CBMP to strengthen the immune system and thus have the ability to kill tumour cells. It is the aim that the patients will receive three doses during the study period however, if the patient wish and it is recommended by the investigator, patients may receive more than three doses, continuing until progression or as judged by the Investigator. Continued treatment after the 24 week study period is only possible under the condition that no safety issues have been discovered. The interval between injections for continued treatment will be decided based on e.g. tumour response and clinical examinations.

PURPOSE:To solidify an oily substance to facilitate the administration, without making the volume larger and utilizing injurious org. solvents, by mixing an adsorbent with an emulsion of an oily substance emulsified by the use of surfactants and water. CONSTITUTION:An oily substance (e.g., vitamin A, vitamin E, castor oil) is emulsified by the use of surfactants (e.g., polysorbate, polyoxyl stearate) and water. The resulting oily substance emulsion and an adsorbent (e.g., silica, synthetic aluminum silicate) are mixed and then dried. It is possible to facilitate the administration of an oily substance, and to solidify it without making the volume larger and utilizing injurious org. solvents.
Human erythroid p55, an abundantly palmitoylated erythrocyte membrane protein, has been identified, cloned and sequenced. p55 appears to be ubiquitously expressed in human tissues and contains both an SH3 motif and an enzymatically active guanylate kinase domain. The presence of the SH3 motif indicates a possible role in the suppression of tyrosine kinase activity and the guanylate kinase domain may play a role in signal transduction and tissue proliferation by modulating guanine nucleotide levels. Localized to the Xq24-qter region of the X chromosome, abnormalities in p55 appear in patients suffering from hemolytic anemia and Dyskeratosis congenita. With the identification and sequencing of p55, nucleic acid probes and anti-p55 antibodies can be used in a variety of hybridization and immunological assays to screen for and detect p55 defects. Conventional and gene techniques can also be developed to treat p55 deficiencies and abnormalities.
