The purpose of this feasibility study is to inform the design of a future large-scale, randomized trial that will test if there is added benefit to addressing both social and economic needs and diabetes self-management to improve diabetes management long-term among vulnerable populations. In this pilot, the investigator will randomize 100 African-American, Hispanic, and/or Medicaid (all race/ethnicities) patients from Kaiser Permanente Northwest (KPNW) with A1C ≥ 8 and poor follow-up in primary care to one of two 6-month interventions: 1) patient navigation only; or 2) patient navigation + diabetes self-management training. In both study arms, KPNW practice-embedded patient navigators will screen for medical, social and economic needs and connect participants to internal and external resources. In the second study arm, navigators will also refer participants to community health workers (CHWs) embedded in local community-based organizations, who will deliver diabetes self-management training. Feasibility of the full-scale trial will be based on several measures including recruitment, retention, success rate of referrals to navigators and CHWs, and whether medical, social, and/or economic needs are met. Qualitative interviews will be conducted with various stakeholders to assess intervention acceptability and determinants of implementation. Preliminary effects of A1C, diabetes-related care gaps, health care utilization, and medication adherence will also be examined. This pragmatic study design involves a collaborative effort among researchers, health system staff, health system senior leadership, and local community-based organizations. Findings from the full-scale trial will contribute critical knowledge on the most effective, sustainable model of care for integrating lay health workers in the efforts to improve diabetes management among high risk patient populations.
The present invention relates to a novel mammalian anti-opioid receptor protein (OFQR), peptide ligands (such as OFQ) that bind to OFQR, and methods of using the OFQ peptide and analogues to reverse the physiologic effects of opiates such as morphine. The isolation, characterization and pharmacological use of the endogenous peptide ligand is described. A particular embodiment of the OFQ peptide is a heptadecapeptide having an FGGF aminoterminal motif. The peptide specifically binds to an OFQ receptor protein heterologously expressed in mammalian cells. The peptide does not bind with high affinity to µ, .delta. or  receptors, but it antagonizes opioid mediated effects (such as analgesia and hypothermia) without increasing nociceptive sensitivity.  Tyrosine substitution variants of the peptide ligand specifically bind to the opioid receptor and can be radioiodinated. Also provided are methods of making such peptide ligands and OFQR antagonists, and methods of using the ligands for diagnostic and therapeutic uses and for the identification of other naturally-occurring or synthetic opioid receptor ligands.
This is a double-blind, placebo-controlled trial of the effects of memantine in adult epilepsy patients. Patients will be assessed for neurocognitive outcomes, seizure frequency and side effects. After a two-month prospective baseline during which seizure frequency and neurocognitive parameters are documented, patients will be randomized to either memantine or placebo and evaluated after twelve months on study drug. The treatment period will consist of a one month dose escalation phase, followed by an eleven month maintenance phase. The dose escalation is 5 mg in PM for days 1-7, 5 mg twice daily for days 8-14, 5 mg in AM and 10 mg in PM for days 15-21 and 10 mg twice daily from day 22 and continue. The neuropsychological battery performed during baseline will be repeated at the end of the twelve month treatment period. No special procedures are required for this study, except the neuropsychological testing, which is not a routinely performed evaluation for adult epilepsy outpatients.
The patient will be placed in the prone position and undergo a standard Gd contrast-enhanced bilateral breast MRI. Immediately after the prone MRI is completed, the patient will be repositioned for the supine MRI. Prior to starting the prone MRI, the study MRI technician/investigator will explain to the patient and practice with the patient the steps needed to transition from the prone to the supine MRI, so as to facilitate a timely transition. Additional MRI images will only take about 10-15 minutes to obtain and will not require a second injection of contrast material.
The invasion and metastasis of tumors pose significant challenges in the treatment of ovarian cancer (OC), making it difficult to cure. One potential treatment approach that has gained attention is the use of matrix metalloproteinase reactive controlled release micelle preparations. In this study, we developed a novel PEG5000-PVGLIG-hyaluronic acid docetaxel/bakuchiol (PP-HA-DTX/BAK) micelles formulation with desirable characteristics such as particle size, narrow polydispersity index, and a ZETA potential of approximately -5 mV. The surface modification with HA facilitates tumor penetration into the tumor interior, while the incorporation of DSPE-PEG2000-PVGLIG-PEG5000helps conceal DSPE-PEG2000-HA, reducing off-target effects and prolonging drug circulation timein vivo. Bothin vitroandin vivoexperiments demonstrated that these micelles effectively inhibit proliferation, invasion, and metastasis of OC cells while promoting apoptosis. Therefore, our findings suggest that PP-HA-DTX/BAK micelles represent a safe and effective therapeutic strategy for treating OC.
The invention provides therapeutic particulates including a macrolide, such as rapamycin, in solid state crystalline form, having a size of 20 μm or less, or 10 μm or less. The particulates are formed in one method by preparing a composition with a macrolide and first (e.g., xylene) and second (e.g., an alcohol, acetone, or acetonitrile) solvents. In the composition a maximum solubility for the macrolide that is greater than a maximum solubility of the macrolide dissolved in either the first or second solvent individually. The first and second solvents are then evaporated from the composition to provide the macrolide particulates. In another method, the particulates can be formed by a method including sonication and stirring/evaporation steps, and the particulates can be obtained from a supersaturated solution, formed during the process. Particulates display desirable low polydispersity, and can be used in therapeutic compositions, or can be associated with an implantable or insertable medical device for the treatment of a subject.

Portal hypertension is responsible for the development of portosystemic collaterals. The hemodynamic alternations may result in mucosal and vascular changes along gastrointestinal (GI) tract as well. According to several epidemiological studies, cirrhotic patients are at a higher risk of developing peptic ulcers, delayed healing, and a higher frequency of ulcer recurrence. The death rate from peptic ulcer disease in cirrhotic patients has been reported to be five times higher than that of the general population. The exact mechanism remains incompletely understood, but may be related to impaired mucosal defense mechanisms. Aggressive factors such as Helicobacter pylori and gastric acid may not be the predominant etiology in such circumstances. Sarfeh et al. found gastric mucosa of portal hypertensive rats, compared with that of controls, has distinctive functional and histologic abnormalities that can explain its increased susceptibility to erosive injury. Auroux et al. found gastroduodenal ulcer was independently associated only with the severity of the hypertensive gastropathy in cirrhotics. Chen et al. found portal hypertension with a hepatic venous pressure gradient \> 12 mmHg may be an important factor contributing to the increased prevalence of gastric ulcer observed in patients with liver cirrhosis. Thereby, we presumed that clinically significant portal hypertension may play a role in development of peptic ulcer in cirrhotic patients. Lebrec et al. elucidated non-selective beta-blocker (NSBB) could significantly decrease portal pressure and lower the risk of GI bleeding in patients with cirrhosis. Kitano et al. found portal hypotensive treatment with NSBB, reduces ethanol-induced gastric mucosal damage in portal hypertensive rats and improves endoscopic signs of portal hypertensive gastropathy in cirrhosis patients. We designed a 2-year randomized trial to evaluate the effectiveness of proton pump inhibitor with or without propranolol on ulcer healing and the incidence of ulcer bleeding in patients with cirrhosis and peptic ulcers.
Benign prostatic hyperplasia (BPH) is one of the most common diseases in elderly men worldwide that may result in lower urinary tract symptoms (LUTS). At present, the specific pathophysiological mechanism for BPH/LUTS LUTS remains unclear. S100 calcium binding protein A4 (S100A4), a member of the calcium binding protein family, regulates a variety of biological processes including cell proliferation, apoptosis and fibrosis. The aim of the current study was to explore and clarify the possible role of S100A4 in BPH/LUTS. The human prostate stromal cell line (WPMY-1), rat prostate epithelial cells, human prostate tissues and two BPH rat models were employed in this study. The expression and localization of S100A4 were detected by quantitative real time PCR (qRT-PCR), immunofluorescence microscopy, Western blotting and immunohistochemistry analysis. Also, S100A4 knockdown or overexpression cell models were constructed and a BPH rat model was induced with testosterone propionate (T) or phenylephrine (PE). The BPH animals were treated with Niclosamide, a S100A4 transcription inhibitor. Results demonstrated that S100A4 was mainly localized in human prostatic stroma and rat prostatic epithelium, and showed a higher expression in BPH. Knockdown of S100A4 induced cell apoptosis, cell proliferation arrest and a reduction of tissue fibrosis markers. Overexpression of S100A4 reversed the aforementioned changes. We also demonstrated that S100A4 regulated proliferation and apoptosis mainly through the ERK pathway and modulated fibrosis via Wnt/β-catenin signaling. In conclusion, our novel data demonstrate that S100A4 could play a crucial role in BPH development and may be explored as a new therapeutic target of BPH.
Hemoglobin H (HbH) disease, a form of alpha-thalassemia, poses significant clinical challenges due to its complex molecular underpinnings. It is characterized by reduced synthesis of the alpha-globin chain. The integration of multi-omics and precision medicine holds immense potential to comprehensively understand and capture interactions at the molecular and genetic levels. This review integrates current multi-omics approaches and advanced technologies in HbH research. Furthermore, it delves into detailed pathophysiology and possible therapeutics in the upcoming future. We explore the role of genomics, transcriptomics, proteomics, and metabolomics studies, alongside bioinformatics tools and gene-editing technologies like CRISPR/Cas9, to identify genetic modifiers, decipher molecular pathways, and discover therapeutic targets. Recent advancements are unveiling novel genetic and epigenetic modifiers impacting HbH disease severity, paving the way for personalized precision medicine interventions. The significance of multi-omics research in unraveling the complexities of rare diseases like HbH is underscored, highlighting its potential to revolutionize clinical practice through precision medicine approaches. This paradigm shift can pave the way for a deeper understanding of HbH complexities and improved disease management.
Chronic Lymphocytic Leukemia (CLL) is the most common form of adult leukemia in the U.S. Recent experience with Nipent in conjunction with Rituxan has shown that this combination is well tolerated and is clinically promising. It is expected that the addition of Cytoxan in patients with previously untreated CLL and patients who have relapsed or failed prior therapy may benefit from combined therapy using Nipent, Cytoxan and Rituxan. It is unknown how the addition of Cytoxan will affect the toxicity profile of the Rituxan and Nipent regimen, however, patients will be monitored for toxicities. It is expected that bone marrow toxicities will not increase to unreasonable levels.

The primary objective of the study is to determine the overall efficacy response rate following treatment with Nipent, Cytoxan and Rituxan of patients with previously untreated or treated CLL. The secondary objectives of the study are to determine the duration of response, time to progression, time to treatment failure and to evaluate the toxicity of this combination of drugs and the incidence and severity of adverse events.

All participants will be administered Pembrolizumab 200mg IV on day 1 and Lenvatinib 20mg PO daily days 1-21 of each cycle (21 days).
BACKGROUND: Research on the imbalance of proopiomelanocortin (POMC)/agouti-related protein (AgRP) neurons in the hypothalamus holds potential insights into the pathophysiology of diabetes. Jinkui Shenqi pills (JSP), a prevalent traditional Chinese medicine, regulate hypothalamic function and treat diabetes.
PURPOSE: To investigate the hypoglycemic effect of JSP and explore the probable mechanism in treating diabetes.
METHODS: A type 2 diabetes mouse model was used to investigate the pharmacodynamics of JSP. The glucose-lowering efficacy of JSP was assessed through various metrics including body weight, food consumption, fasting blood glucose (FBG), serum insulin levels, and an oral glucose tolerance test (OGTT). To elucidate the modulatory effects of JSP on hypothalamic mechanisms, we quantified the expression and activity of POMC and AgRP and assessed the insulin-mediated phosphoinositide 3-kinase (PI3K)/protein kinase A (AKT)/forkhead box O1 (FOXO1) pathway in diabetic mice via western blotting and immunohistochemistry. Additionally, primary hypothalamic neurons were exposed to high glucose and palmitic acid levels to induce insulin resistance, and the influence of JSP on POMC/AgRP protein expression and activation was evaluated by PI3K protein inhibition using western blotting and immunofluorescence.
RESULTS: Medium- and high-dose JSP treatment effectively inhibited appetite, resulting in a steady declining trend in body weight, FBG, and OGTT results in diabetic mice (p < 0.05). These JSP groups also had significantly increased insulin levels (p < 0.05). Importantly, the medium-dose group exhibited notable protection of hypothalamic neuronal and synaptic structures, leading to augmentation of dendritic length and branching (p < 0.05). Furthermore, low-, medium-, and high-dose JSP groups exhibited increased phosphorylated (p) INSR, PI3K, pPI3K, AKT, and pAKT expression, as well as decreased FOXO1 and increased pFOXO1 expression, indicating improved hypothalamic insulin resistance in diabetic mice (p < 0.05). Treatment with 10% JSP-enriched serum produced a marked elevation of both expression and activation of POMC (p < 0.05), with a concurrent reduction in AgRP expression and activation within primary hypothalamic neurons (p < 0.05). Intriguingly, these effects could be attributed to the regulatory dynamics of PI3K activity.
CONCLUSION: Our findings suggest that JSP can ameliorate diabetes by regulating POMC/AgRP expression and activity. The insulin-mediated PI3K/AKT/FOXO1 pathway plays an important regulatory role in this intricate process.

The airway epithelium is located at the interactional boundary between the external and internal environments of the organism and is often exposed to harmful environmental stimuli. Inflammatory response that occurs after airway epithelial stress is the basis of many lung and systemic diseases. Chloride intracellular channel 4 (CLIC4) is abundantly expressed in epithelial cells. The purpose of this study was to investigate whether CLIC4 is involved in the regulation of lipopolysaccharide (LPS)-induced inflammatory response in airway epithelial cells and to clarify its potential mechanism. Our results showed that LPS induced inflammatory response and decreased CLIC4 levels in vivo and in vitro. CLIC4 silencing aggravated the inflammatory response in epithelial cells, while overexpression of CLIC4 combined with LPS exposure significantly decreased the inflammatory response compared with cells exposed to LPS without CLIC4 overexpression. By labeling intracellular chloride ions with chloride fluorescent probe MQAE, we showed that CLIC4 mediated intracellular chloride ion-regulated LPS-induced cellular inflammatory response.
PURPOSE: Middle segment-preserving pancreatectomy (MSPP) is a relatively new parenchymal-sparing surgery that has been introduced as an alternative to total pancreatectomy (TP) for multicentric benign and borderline pancreatic diseases. To date, only 36 cases have been reported in English.
METHODS: We reviewed 22 published articles on MSPP and reported an additional case.
RESULTS: Our patient was a 49-year-old Japanese man diagnosed with Zollinger-Elison syndrome (ZES) caused by duodenal and pancreatic gastrinoma associated with multiple endocrine neoplasia syndrome type 1. We avoided TP and chose MSPP as the operative technique due to his relatively young age. The patient developed a grade B postoperative pancreatic fistula (POPF), which improved with conservative treatment. He was discharged without further treatment. To date, no tumor has recurred, and pancreatic function seems to be maintained. According to a literature review, the morbidity rate of MSPP is as high as 54%, mainly due to the high incidence of POPF (32%). In contrast, there was no perioperative mortality, and postoperative pancreatic function was comparable to that after conventional pancreatectomy.
CONCLUSIONS: Despite the high incidence of POPF, MSPP appears to be safe, with low perioperative mortality and good postoperative pancreatic sufficiency.
