Background: Fluid treatment in sepsis is a challenge and clinical equipoise exists regarding intravenous (IV) volumes. We aimed to determine whether a 24‐h protocol restricting IV fluid was feasible in adult patients with sepsis without shock presenting to the emergency department (ED). Methods: The REFACED Sepsis trial is an investigator‐initiated, multicenter, randomized, open‐label, feasibility trial, assigning sepsis patients without shock to 24 h of restrictive, crystal IV fluid administration or standard care. In the IV fluid restriction group fluid boluses were only permitted if predefined criteria for hypoperfusion occurred. Standard care was at the discretion of the treating team. The primary outcome was total IV crystalloid fluid volumes at 24 h after randomization. Secondary outcomes included total fluid volumes, feasibility measures, and patient‐centered outcomes. Results: We included 123 patients (restrictive 61 patients and standard care 62 patients) in the primary analysis. A total of 32% (95% confidence interval [CI] 28%–37%) of eligible patients meeting all inclusion criteria and no exclusion criteria were included. At 24 h, the mean (±SD) IV crystalloid fluid volumes were 562 (±1076) ml versus 1370 (±1438) ml in the restrictive versus standard care group (mean difference –801 ml, 95% CI −1257 to −345 ml, p = 0.001). Protocol violations occurred in 21 (34%) patients in the fluid‐restrictive group. There were no differences between groups in adverse events, use of mechanical ventilation or vasopressors, acute kidney failure, length of stay, or mortality. Conclusions: A protocol restricting IV crystalloid fluids in ED patients with sepsis reduced 24‐h fluid volumes compared to standard care. A future trial powered toward patient‐centered outcomes appears feasible. [ABSTRACT FROM AUTHOR]

Background: Stem cell therapy is a novel treatment option for people living with osteoarthritis. Research investigating stem cell therapy for this debilitating condition has predominantly involved the pathogenesis of the cells and efficacy of the treatment. There is little understanding of patients' expectations and experiences of stem cell therapy treatment. Objective: To explore the expectations and experiences of people undergoing stem cell therapy for the treatment of knee osteoarthritis. Design: An exploratory, descriptive, qualitative study using semi‐structured interviews was conducted. Setting and participants: Participants were recruited into two groups: (a) Expectations Group (n = 15); the expectations of stem cell treatment were explored with participants that were yet to commence stem cell therapy. (b) Experiences Group (n = 15); the experiences of stem cell therapy were explored with participants 12 months after their initial stem cell treatment. Transcripts were analysed using thematic analysis to identify themes in both groups. Results: Themes for the Expectations Group were active involvement in the treatment; treatment will improve symptoms; and benefits of treatment outweigh the risks. Themes for the Experiences Group were symptoms of treatment; satisfaction with treatment; and anticipation of further improvement. Discussion and conclusions: The findings are the first qualitative study to represent patients' perspective on expectations and experiences of stem cell therapy for knee osteoarthritis. They provide insight into the potential areas for improvement within this field to aid patients' preparation and approach to the treatment, promoting patient‐centred care. [ABSTRACT FROM AUTHOR]

We report the rationale and design of a community PHARMacy-based prospective randomized controlled interdisciplinary study for ambulatory patients with Chronic Heart Failure (PHARM-CHF) and results of its pilot study. The pilot study randomized 50 patients to a pharmacy-based intervention or usual care for 12 months. It demonstrated the feasibility of the design and showed reduced systolic blood pressure in the intervention group as indicator for improved medication adherence. The main study will randomize patients ≥60 years on stable pharmacotherapy including at least one diuretic and a history of heart failure hospitalization within 12 months. The intervention group will receive a medication review at baseline followed by regular dose dispensing of the medication, counselling regarding medication use and symptoms of heart failure. The control patients are unknown to the pharmacy and receive usual care. The primary efficacy endpoint is medication adherence, pre-specified as a significant difference of the proportion of days covered between the intervention and control group within 365 days following randomization using pharmacy claims data for three CHF medications (angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, beta-blockers, and mineralocorticoid receptor antagonists). The primary composite safety endpoint is days lost due to blindly adjudicated unplanned cardiovascular hospitalizations or death. Overall, 248 patients shall be randomized. The minimum follow-up is 12 months with an expected mean of 24 months. Based on the feasibility demonstrated in the pilot study, the randomized PHARM-CHF trial will test whether an interdisciplinary pharmacy-based intervention can safely improve medication adherence and will estimate the potential impact on clinical endpoints.

Background and Purpose: Parkinson's disease (PD) is a neurodegenerative disorder closely associated with dopaminergic neuron loss. It is well documented that Achyranthes bidentata polypeptides (ABPP) are potent neuroprotective agents in several kinds of neurons. Therefore, we proposed that ABPP might play a beneficial role against PD by protecting dopaminergic neurons from apoptosis.Experimental Approach: SH-SY5Y cells and primary rat dopaminergic neurons were pretreated with ABPP fraction k (ABPPk), a purified fraction of ABPP, and then the cells were exposed to 1-methyl-4-phenylpyridinium iodide (MPP+ ) to induce apoptosis. Cell viability, LDH activity, a Tunel assay and protein levels of Bcl-2 and Bax were analysed. In an in vivo PD model induced by MPTP, ABPPk was intranasally delivered to mice. Behavioural tests, immunohistochemistry, immunostaining, Nissl staining, qRT-PCR and Western blot were employed to evaluate the potential effects of ABPPk on PD in mice.Key Results: The application of ABPPk markedly enhanced the viability of SH-SY5Y cells and primary dopaminergic neurons treated with neurotoxic agent MPP+ . In an in vivo MPTP-induced PD model, ABPPk significantly improved behavioural performances and prevented tyrosine hydroxylase loss in the substantia nigra pars compacta and striatum. Furthermore, we showed that MPTP-induced astrocyte and microglia activation were largely attenuated by ABPPk, leading to low levels of neuroinflammation and a downregulation of the apoptotic signalling pathway.Conclusion and Implications: Taken together, our data show that ABPPk protects dopaminergic neurons from apoptosis, suggesting that ABPPk might be an effective intervention for treating the neuron loss associated with disorders such as PD.

Objective: The ketones d-β-hydroxybutyrate (BHB) and acetoacetate are elevated during prolonged fasting or during a "ketogenic" diet. Although weight loss on a ketogenic diet may be associated with decreased appetite and altered gut hormone levels, it is unknown whether such changes are caused by elevated blood ketones. This study investigated the effects of an exogenous ketone ester (KE) on appetite.Methods: Following an overnight fast, subjects with normal weight (n = 15) consumed 1.9 kcal/kg of KE, or isocaloric dextrose (DEXT), in drinks matched for volume, taste, tonicity, and color. Blood samples were analyzed for BHB, glucose, insulin, ghrelin, glucagon-like peptide 1 (GLP-1), and peptide tyrosine tyrosine (PYY), and a three-measure visual analogue scale was used to measure hunger, fullness, and desire to eat.Results: KE consumption increased blood BHB levels from 0.2 to 3.3 mM after 60 minutes. DEXT consumption increased plasma glucose levels between 30 and 60 minutes. Postprandial plasma insulin, ghrelin, GLP-1, and PYY levels were significantly lower 2 to 4 hours after KE consumption, compared with DEXT consumption. Temporally related to the observed suppression of ghrelin, reported hunger and desire to eat were also significantly suppressed 1.5 hours after consumption of KE, compared with consumption of DEXT.Conclusions: Increased blood ketone levels may directly suppress appetite, as KE drinks lowered plasma ghrelin levels, perceived hunger, and desire to eat.

Aims: In the ENGAGE AF-TIMI 48 trial, edoxaban, a factor Xa inhibitor, was not found to be inferior to warfarin for the prevention of stroke or systemic embolic events (SEE) in patients with atrial fibrillation (AF) and was associated with significantly less bleeding. The higher-dose edoxaban regimen (HDER; 60 mg dose-reduced to 30 mg once daily) has been approved in various countries in Europe, the USA, and Japan. Among patients treated with vitamin K antagonists (VKAs), symptomatic heart failure (HF) is an independent risk factor for lower time-in-therapeutic range, which reduces the efficacy and safety of VKA therapy. We evaluated the efficacy and safety of edoxaban compared with warfarin across the spectrum of HF severity in the ENGAGE AF-TIMI 48 trial.Methods and Results: Of 14 071 patients randomized to well-controlled warfarin or the HDER, 5926 (42%) had no history of HF, 6344 (45%) were in New York Heart Association (NYHA) class I-II, and 1801 (13%) were in NYHA class III-IV. The efficacy of edoxaban compared with warfarin in preventing stroke/SEE was similar in patients without and with HF regardless of the severity of HF; [HDER vs. warfarin: No-HF: hazard ratio (HR) 0.87, 95% confidence interval (CI) 0.69-1.11; NYHA class I-II: HR 0.88, 95% CI 0.69-1.12; NYHA class III-IV: HR 0.83, 95% CI 0.55-1.25; Pinteraction = 0.97]. Compared with warfarin, HDER was consistently associated with lower risk of major bleeding (No-HF: HR 0.82, 95% CI 0.68-0.99; NYHA class I-II: HR 0.79, 95% CI 0.65-0.96; NYHA class III-IV: HR 0.79, 95% CI 0.54-1.17; Pinteraction = 0.96).Conclusion: The relative efficacy and safety of HDER compared with well-managed warfarin in AF patients with HF were similar to those without HF.

Aims: Hyperkalaemia in heart failure patients limits use of cardioprotective renin-angiotensin-aldosterone system inhibitors (RAASi). Sodium zirconium cyclosilicate (ZS-9) is a selective potassium ion trap, whose mechanism of action may allow for potassium binding in the upper gastrointestinal tract as early as the duodenum following oral administration. ZS-9 previously demonstrated the ability to reduce elevated potassium levels into the normal range, with a median time of normalization of 2.2 h and sustain normal potassium levels for 28 days in HARMONIZE--a Phase 3, double-blind, randomized, placebo-controlled trial. In the present study we evaluated management of serum potassium with daily ZS-9 over 28 days in heart failure patients from HARMONIZE, including those receiving RAASi therapies.Methods and Results: Heart failure patients with evidence of hyperkalaemia (serum potassium ≥5.1 mmol/L, n = 94) were treated with open-label ZS-9 for 48 h. Patients (n = 87; 60 receiving RAASi) who achieved normokalaemia (potassium 3.5-5.0 mmol/L) were randomized to daily ZS-9 (5, 10, or 15 g) or placebo for 28 days. Mean potassium and proportion of patients maintaining normokalaemia during days 8-29 post-randomization were evaluated. Despite RAASi doses being kept constant, patients on 5 g, 10 g, and 15 g ZS-9 maintained a lower potassium level (4.7 mmol/L, 4.5 mmol/L, and 4.4 mmol/L, respectively) than the placebo group (5.2 mmol/L; P<0.01 vs. each ZS-9 group); greater proportions of ZS-9 patients (83%, 89%, and 92%, respectively) maintained normokalaemia than placebo (40%; P < 0.01 vs. each ZS-9 group). The safety profile was consistent with previously reported overall study population.Conclusion: Compared with placebo, all three ZS-9 doses lowered potassium and effectively maintained normokalaemia for 28 days in heart failure patients without adjusting concomitant RAASi, while maintaining a safety profile consistent with the overall study population.
