The JuLi Registry seeks to fill some of the gaps associated with the clinical use of CBD (cannabidiol) and other cannabinoid formulations including THC and others. The overarching goal of this Registry is to rapidly advance research and understanding of the use of cannabis and hemp-based formulations, in the clinical community setting, when it is utilized to manage the symptoms of cancer treatment and other underlying health issues. These symptoms include nausea, neuropathy, and sleeplessness and chronic pain.
This study looks at how hypertensive patients, with high levels of aldosterone (hyperaldosteronism) differ from hypertensive patients without hyperaldosteronism with regards to markers of salt appetite. It also looks at how salt appetite changes after treatment of hyperaldosteronism. Salt makes food taste good and when our bodies need salt our brains make us like salty food even more. A high salt diet contributes to hypertension and a low salt diet is an important aspect of the treatment of hypertension. Unfortunately patients find it difficult to adhere to a low salt diet. Aldosterone is produced by the adrenal glands, its release is stimulated by a salt need and it has been shown, in rodent models, to activate pathways in the brain which drive a salt appetite. Mice with enhanced activity of the aldosterone pathway in the brain become hypertensive due to increased salt intake. Hyperaldosteronism, in humans, results in hypertension. The contribution of salt appetite, as opposed to the effect of aldosterone on the kidney's retention of salt and other systems, is unknown. Human studies have shown that when a human has a salt appetite, the concentration at which they can detect the taste of salt reduces, they increase their preference for salty food, and they consume more salt. When hyperaldosteronism is suspected in a hypertensive patient, they attend hospital for a day of investigations. Patient who are shown to have hyperaldosteronism have subsequent visits for imaging of their adrenals and sampling of blood from the adrenal vein to diagnose aldosterone producing adenomas (small tumours) which may be removed surgically, if not suitable for surgery, the hyperaldosteronism is treated with medication. This study will recruit hyperaldosteronism patients to investigate the effect of aldosterone on salt appetite by testing salt taste threshold, salt taste preference and intake before and after treatment.
The incidence of oesophagogastric cancer has increased by 400% since the 1970s in Ireland and the United Kingdom. In addition, refinement of perioperative management and the now widespread use of multimodal protocols for patients with locally advanced disease have significantly improved outcomes for patients with oesophagogastric cancer treatable with curative intent. Despite significant advances in chemoradiotherapy, surgical resection remains the primary curative option. Unintentional weight loss and nutritional complications represent serious concerns for patients after radical resection, even among those who remain free from recurrent disease in the long-term. A study from the Swedish Esophageal and Cardia Cancer Registry reported a mean three year weight loss of 10.8% among disease-free patients, with 33.8% of this cohort demonstrating malnutrition at three years post-oesophagectomy. Mechanisms contributing to weight loss for disease-free patients after upper gastrointestinal surgery are poorly understood, however an association between increasing magnitude of weight loss and the presence of increased satiety is described. Our recent studies at SJH have demonstrated four fold elevated postprandial satiety gut hormone concentrations after oesophagectomy, compared with baseline preoperative values. Postprandial gut hormone levels correlate significantly with postprandial symptoms and altered appetite at 3 months postoperatively, and with body weight loss at 2 years postoperatively. However, the mechanism leading to exaggerated postprandial gut hormone production after upper gastrointestinal surgery is poorly understood, limiting targeted therapeutic options. In this study, we aim to characterise the role of altered nutrient transit and enteroendocrine cell function in the pathophysiology of excessive post-prandial gut hormone responses after upper gastrointestinal surgery. To do this, we will measure the gut hormone response to a standardised 400 kcal meal, as per previous studies, while concurrently assessing gastrointestinal transit time, and enteroendocrine cell morphology and function. In this way, we will determine whether the magnitude of the postprandial gut hormone response correlates with the rate of nutrient transit into the enteroendocrine L-cell rich small intestine, and whether enteroendocrine cell adaptation occurs after oesophagectomy. Furthermore, we have previously observed that gut hormone suppression using octreotide is associated with increased ad libitum among subjects after upper gastrointestinal cancer surgery (Elliott JA et al, Annals of Surgery, 2015). The mechanism of action of octreotide may relate to SSTR-5-mediated negative feedback to the enteroendocrine L-cell, but this medication may additionally reduce enteroendocrine L-cell responses through its inhibitory effect on gastrointestinal motility - reducing the rapidity with which nutrients are delivered to the small intestine - and small intestinal nutrient sensing via inhibition of the Na+-dependent glucose transporter SGLT-18-10. Through conduction of this double-blind, randomised, placebo-controlled crossover study, we aim to establish the mechanism of action of octreotide-mediated increased food intake in patients after gastrointestinal surgery. This may inform the design of future targeted interventions for this patient group.
The study will be performed in two parts: 1) The pharmacokinetic (PK) part and 2) The appetite and nutritional evaluation part. The PK part of study will be conducted in open label manner on 10 end stage kidney disease (ESKD) patients receiving maintenance hemodialysis (MHD) treatment. For the PK part, a starting dose of cannabis oil -1 drop of 3% cannabis oil once a day [each drop contain 1.2 mg CBD (cannabidiol) and 1.2 mg of ∆9-THC (∆9-tetrahydrocannabinol)], was judged to be safe for a first-in-MHD patient's administration. Escalation to the next higher dose and any dose adjustments of the next dose levels will be based on safety and tolerability results of the previously administered dose and available PK data of previous dose groups. Once the first dosage proved to be safe, there will be a 2 fold increase from the first dose level (2 drops once a day) to the second dose level. The dose levels will be increased by 2-fold from the previous dose level, until basal hunger and prospective consumption ratings assessed by the visual analogue scale (VAS) will increase at least by 10 mm between screening and the study visits (change-from-baseline) . PK parameters will be evaluated after first dosage administration and after dosage increased. The appetite and nutritional evaluation part of study will be conducted as a 3-month, double-blind, parallel-group, placebo-controlled, single center study. The study population will include 30 ESKD patients receiving MHD treatment with different degrees of protein-energy wasting (PEW) defined as malnutrition-inflammation score (MIS) above 6. A total of 30 subjects will be randomized to treatment with either cannabis oil or matching placebo.
This study will examine the effects of almonds consumed by adults with different body fat distributions on indices of carbohydrate and lipid metabolism.
The global research project was organized as a clinical process starting with an evaluation aiming at the determination of a diagnosis pertaining to the degree of satiety signal capacity. It was extended by a phase of metabolic and behavioural characterization to better understand the clinical condition of the patients. The main part of the program was a weight loss intervention that was focused on high satiating foods. Finally, the process was completed by an evaluation allowing to determine the impact of the intervention on the metabolic and behavioural conditions of the patients.
Zinc supplementation effect on appetite and growth of malnourished children
Anorexia means loss of appetite. But there is disagreement about whether the appetite is changed by the disease anorexia nervosa (AN). Appetite is a subjective essential sense, which is regulated in a complex ensemble between brain, stomach - intestinal system and hormones. As a direct result of malnutrition, there are many somatic complications caused by the disease AN. Several of these complications may in itself affect hunger- and satiety perception. An example of this is delayed gastric emptying. Furthermore, changes in the hormone systems affects the biological "reward system" in the brain, which plays an important role in appetite regulation. There is clearly need for research that could lead to better treatments for AN. Hunger- and satiety perception has only been studied in a few small cross-sectional studies with no clear conclusion. The purpose of the study is to determine whether a visual analog scale measurement can detect changes in hunger- and satiety perception in a least 30 patients admitted to nutrition for life-threatening severe anorexia nervosa. It may lead to the first step in the development of a simple and inexpensive instrument which may prove to be useful in measuring the impact of new and ongoing treatments of the disease.
