Feasibility and Efficacy of a Novel Mindfulness App Used With Matcha Green Tea in Generally Healthy Adults: Randomized Controlled Trial.

Background: Mindfulness practices, such as breathing meditation (BM), reduce stress and enhance mood. One such practice is mindful eating, where a practitioner focuses on the five senses while eating or drinking. A novel set of prototypes has been developed, incorporating principles of mindful eating.

Change in liking following reduction in sweetness level of carbonated beverages: a randomized controlled parallel trial.

Despite recommendations to reduce sweet-tasting foods and beverage consumption, there is limited understanding of our ability to adapt to a less sweet diet and the optimal method for doing so. Thus, we conducted two parallel, double-blind, randomized controlled trials in the USA and Mexico to investigate whether different methods of reducing sweetness could change sweetness preferences. Over 6 months, habitual consumers of full-sugar sweetened (FSS-CSD) or low-calorie sweetened carbonated soft drinks (LCS-CSD) consumed a full sweetness CSD (Control), CSD with gradually decreasing sweetness levels (StepR), and a reduced sweetness test CSD (DirR).

Supplementation of spermidine at 40 mg/day has minimal effects on circulating polyamines: An exploratory double-blind randomized controlled trial in older men.

This study represents the first investigation into the safety of a novel, high-purity spermidine trihydrochloride supplement (hpSPD) in humans. Spermidine, a natural compound found in various foods, has demonstrated potential health benefits in animal and epidemiological studies. However, evidence from clinical trials and safety evaluations of spermidine supplements is limited because pure spermidine for human administration has not been available.

Rationale and protocol for a safety, tolerability and feasibility randomized, parallel arm, double-blind, placebo-controlled, pilot study of a novel ketone ester targeting frailty via immunometabolic geroscience mechanisms.

Background: Frailty is a geriatric syndrome characterized by chronic inflammation and metabolic insufficiency that creates vulnerability to poor outcomes with aging. We hypothesize that interventions which target common underlying mechanism of aging could ameliorate frailty. Ketone bodies are metabolites produced during fasting or on a ketogenic diet that have pleiotropic effects on inflammatory and metabolic aging pathways in laboratory animal models.

Daily consumption of ketone ester, bis-octanoyl (R)-1,3-butanediol, is safe and tolerable in healthy older adults in a randomized, parallel arm, double-blind, placebo-controlled, pilot study.

Objectives: Ketone bodies are endogenous metabolites produced during fasting or a ketogenic diet that have pleiotropic effects on aging pathways. Ketone esters (KEs) are compounds that induce ketosis without dietary changes, but KEs have not been studied in an older adult population. The primary objective of this trial was to assess the tolerability and safety of KE ingestion in a cohort of older adults.

The effect of vitamin E and docosahexaenoic acid ethyl ester on Metabolic Dysfunction-Associated steatotic Liver Disease (MASLD)-A randomised, double-blind, placebo-controlled, parallel-group clinical trial (PUVENAFLD).

Aims: We conducted a clinical trial to determine the efficacy of the combination of vitamin E and/or docosahexaenoic acid (DHA) versus placebo in reducing liver fat content after 6 months of intervention in adults with MASLD.

Methods: Adults with MASLD were randomised to one of four treatment arms (vitamin E 1000 mg/daily + DHA 1.89 g/daily or combination arm, vitamin E 1000 mg alone, DHA 1.

Rationale and protocol for a safety, tolerability and feasibility randomized, parallel group, double-blind, placebo-controlled, pilot study of a novel ketone ester targeting frailty via immunometabolic geroscience mechanisms.

Background: Frailty is a geriatric syndrome characterized by chronic inflammation and metabolic insufficiency that creates vulnerability to poor outcomes with aging. We hypothesize that geroscience interventions, which target mechanisms of aging, could ameliorate frailty. Metabolites such as ketone bodies are candidate geroscience interventions, having pleiotropic effects on inflammo-metabolic aging mechanisms.

A randomized, open-label, parallel pilot study investigating metabolic product kinetics of the novel ketone ester, bis-hexanoyl (R)-1,3-butanediol, over one week of ingestion in healthy adults.

Bis-hexanoyl (R)-1,3-butanediol (BH-BD) is a novel ketone ester that, when consumed, is hydrolyzed into hexanoic acid (HEX) and (R)-1,3-butanediol (BDO) which are subsequently metabolized into beta-hydroxybutyrate (BHB). We undertook a randomized, parallel, open-label study in healthy adults ( = 33) to elucidate blood BHB, HEX and BDO concentrations for 8 h following consumption of three different serving sizes (SS) of BH-BD (12.5, 25 and 50 g/day) before (Day 0) and after 7 days of daily BH-BD consumption (Day 7).

The probiotic BS50 decreases gastrointestinal symptoms in healthy adults: a randomized, double-blind, placebo-controlled trial.

Abstract: Durable spore-forming probiotics are increasingly formulated into foods, beverages, and dietary supplements. To help meet this demand, the safety and efficacy of daily supplementation of Bacillus subtilis BS50 for 6 weeks was investigated in a randomized, double-blind, placebo-controlled, parallel clinical trial of 76 healthy adults. Before and during supplementation, gastrointestinal symptoms were recorded daily using a multi-symptom questionnaire.

Moderate intakes of soluble corn fibre or inulin do not cause gastrointestinal discomfort and are well tolerated in healthy children.

We investigated the gastrointestinal (GI) tolerance of soluble corn fibre (SCF) compared with inulin in children 3-9 years old. SCF (3-8 g/d for 10d) was tolerated as well as inulin: no differences were identified in stool frequency and consistency, proportion of subjects with at least one loose stool or reporting symptoms during bowel movement. Compared to inulin, 6 g/d of SCF lowered gas severity in children aged 3-5 years old.

Bowel habits, faecal microbiota and faecal bile acid composition of healthy adults consuming fruit pomace fibres: two-arm, randomised, double-blinded, placebo-controlled trials.

Dietary fibre modulates gastrointestinal (GI) health and function, providing laxation, shifting microbiota, and altering bile acid (BA) metabolism. Fruit juice production removes the polyphenol- and fibre-rich pomace fraction. The effects of orange and apple pomaces on GI outcomes were investigated in healthy, free-living adults.

Predictors of thrombosis in children receiving therapy for acute lymphoblastic leukemia: Results from Dana-Farber Cancer Institute ALL Consortium trial 05-001.

Background/objectives: Although thromboembolism (TE) is a serious complication in patients with acute lymphoblastic leukemia (ALL), thromboprophylaxis is not commonly used due to the inherent bleeding risk in this population. Identifying prothrombotic risk factors will help target thromboprophylaxis to those at highest thrombotic risk. We aimed to define predictors and the impact of TE on ALL outcome in children (1-18 years) treated on the Dana-Farber Cancer Institute ALL 05-001 trial.

Ocular abnormalities at diagnosis and after the completion of treatment in children and adolescents with newly diagnosed acute lymphoblastic leukemia.

Background: Ocular abnormalities (OA) in pediatric patients with acute lymphoblastic leukemia (ALL) are common findings both at diagnosis and later in follow-up. The frequency, predictors, and prognostic impact of OA in the context of recent ALL protocols are not well characterized.

Procedure: Single-center retrospective analysis of the medical records of 224 patients with ALL enrolled on Dana-Farber Cancer Institute (DFCI) ALL Consortium Protocol 05-001.

Ixazomib in addition to chemotherapy for the treatment of acute lymphoblastic leukemia in older adults.

We sought to assess the safety of adding ixazomib, an oral proteasome inhibitor, to a multi-agent treatment regimen for older adults with acute lymphoblastic leukemia (ALL). Patients 51 to 75 years of age with newly diagnosed ALL were screened. Induction consisted of prednisone (P), vincristine (V), and doxorubicin (D).

Effect of arabinogalactan on the gut microbiome: A randomized, double-blind, placebo-controlled, crossover trial in healthy adults.

Objective: Promising evidence suggests beneficial health effects of arabinogalactan, but little is known about the effect of this non-digestible carbohydrate on the gut microbiota, a crucial mediator of human health. The objective of this study was to investigate the effect of an arabinogalactan product (ResistAid) on the fecal microbiome and short-chain fatty acids and gastrointestinal tolerance in healthy adults in a randomized, double-blind, crossover trial.

Methods: Thirty adults were randomly assigned to consume 15 g/d maltodextrin (control) or ResistAid for 6 wk.

Matched Targeted Therapy for Pediatric Patients with Relapsed, Refractory, or High-Risk Leukemias: A Report from the LEAP Consortium.

Despite a remarkable increase in the genomic profiling of cancer, integration of genomic discoveries into clinical care has lagged behind. We report the feasibility of rapid identification of targetable mutations in 153 pediatric patients with relapsed/refractory or high-risk leukemias enrolled on a prospective clinical trial conducted by the LEAP Consortium. Eighteen percent of patients had a high confidence Tier 1 or 2 recommendation.

Decision regret, adverse outcomes, and treatment choice in men with localized prostate cancer: Results from a multi-site randomized trial.

Introduction: Men diagnosed with localized prostate cancer must navigate a highly preference-sensitive decision between treatment options with varying adverse outcome profiles. We evaluated whether use of a decision support tool previously shown to decrease decisional conflict also impacted the secondary outcome of post-treatment decision regret.

Methods: Participants were randomized to receive personalized decision support via the Personal Patient Profile-Prostate or usual care prior to a final treatment decision.

Informing models of cancer genetics care in the era of multigene panel testing with patient-led recommendations.

The study describes patient-reported experiences and recommendations to improve the genetic counseling and multigene panel testing (MGPT) process. A descriptive mixed-method study with concurrently collected and integrated qualitative and quantitative data was conducted. Eligible participants were English-speaking adults with a breast or gynecologic cancer diagnosis who had received genetic counseling and testing with a MGPT from one Comprehensive Cancer Center.

Protective Effects of Dietary Intake of Antioxidants and Treatment-Related Toxicity in Childhood Leukemia: A Report From the DALLT Cohort.

Purpose: The benefits and risks of supplementation with antioxidants during cancer therapy have been a controversial area. Few studies have systematically evaluated dietary intake of antioxidants with toxicity and survival in childhood cancer. We sought to determine the role of dietary intake of antioxidants on rates of infections, mucositis, relapse, and disease-free survival during induction and postinduction phases of therapy among children and adolescents with acute lymphoblastic leukemia (ALL).
