Ketonemia Through Menstrual Cycle

EpilepsyDrug Resistant Epilepsy3 more

Ketogenic dietary therapies (KDTs) are well-established, safe, non-pharmacologic treatments used for children and adults with drug-resistant epilepsy and other neurological disorders. Ketone bodies levels undergo a significant inter-individual and intra-individual variability and can be affected by several factors. This evidence suggests the need for personalized monitoring for diet optimization, especially at the beginning of the treatment but during whole follow-up. Possible variations in glycemia and ketone bodies' blood level according to different phases of menstrual cycle have not been systematically assessed yet, but this time window deserves special attention because of hormonal and metabolic related changes. We present the methodological protocol for a longitudinal, multicentric study aimed at searching for subtle changes in ketone bodies blood level during menstrual cycle in epileptic female patients undergoing a stable ketogenic diet. The study will be divided into two phases. The first one will be purely observational, aiming at the assessment of ketonemia during menstrual cycle. Whether this finding will be confirmed, a second phase of ketogenic diet therapy adjustment will be scheduled.

Diabetic Ketoacidosis From New SGLT2i: Can Genomics Estimate Risk

Diabetes Type 2DKA1 more

Sodium glucose co-transporter 2 (SGLT2) inhibitors have revolutionized care for people living with type 2 diabetes mellitus (T2DM). They reduce a person's risk of heart failure, renal failure, myocardial infarction, stroke, cardiovascular mortality, and potentially all-cause mortality. Remarkably, some of these benefits also extend to people who do not have T2DM. While the benefits of SGLT2 inhibitors are impressive, there is one life-threatening side effect associated with their use: diabetic ketoacidosis (DKA). The ability to predict which patients are at highest risk of DKA is needed to sufficiently mitigate this risk. Moreover, considering the impressive benefits of SGLT2 inhibitors, identifying patients at the lowest risk of SGLT2 inhibitor-associated DKA is also important so that providers do not overestimate risk in those who stand to benefit most. Advances in genomic technologies and related analyses have provided unprecedented opportunities to bring genomics-driven precision medicine initiatives to the forefront of clinical research. Leading these developments has been the progress made by genome-wide association studies (GWAS) due to decreasing genotyping costs, and consequently, the ability to routinely study large numbers of patients. These approaches allow for systematic screening of the genome in an unbiased manner and have accelerated the discovery of genetic variants and novel biological processes that contribute to the development of adverse treatment outcomes. By using innovative approaches, which harness large cohorts of population controls, sample size limitations that are associated with rare adverse drug reactions such as SGLT2 inhibitor-associated DKA can be overcome. The DANGER study represents a highly innovative new direction wherein partnership among basic science researchers and computational biologists will lead to the application of genomic techniques to identify genetic variants that may be associated with SGLT2 inhibitor-associated DKA.

Intermittent Exogenous Ketosis (IEK) at High Altitude

KetosisHypoxia

Altitude-related hypoxia decreases human functional capacity, especially during exercise. Even with prolonged acclimatization, the physiological adaptations are insufficient to preserve exercise capacity, especially at higher altitudes completely. Consequently, there has been an ongoing search for various interventions to mitigate the negative effects of hypoxia on human performance and functional capacity. Interestingly, early data in rodents and humans indicate that intermittent exogenous ketosis (IEK) by ketone ester intake improves hypoxic tolerance, i.e.by facilitating muscular and neuronal energy homeostasis and reducing oxidative stress. Furthermore, there is evidence to indicate that hypoxia elevates the contribution of ketone bodies to adenosine-triphosphate (ATP) generation, substituting glucose and becoming a priority fuel for the brain. Nevertheless, it is reasonable to postulate that ketone bodies might also facilitate long-term acclimation to hypoxia by upregulation of both hypoxia-inducible factor-1α and stimulation of erythropoietin production. The present project aims to comprehensively investigate the effects of intermittent exogenous ketosis on physiological, cognitive, and functional responses to acute and sub-acute exposure to altitude/hypoxia during rest, exercise, and sleep in healthy adults. Specifically, we aim to elucidate 1) the effects of acute exogenous ketosis during submaximal and maximal intensity exercise in hypoxia, 2) the effects of exogenous ketosis on sleep architecture and quality in hypoxia, and 3) the effects of exogenous ketosis on hypoxic tolerance and sub-acute high-altitude adaptation. For this purpose, a placebo-controlled clinical trial (CT) in hypobaric hypoxia (real high altitude) corresponding to 3375 m a.s.l. (Rifugio Torino, Courmayeur, Italy) will be performed with healthy individuals to investigate both the functional effects of the tested interventions and elucidate the exact physiological, cellular, and molecular mechanisms involved in acute and chronic adaptation to hypoxia. The generated output will not only provide novel insight into the role of ketone bodies under hypoxic conditions but will also be of applied value for mountaineers and athletes competing at altitude as well as for multiple clinical diseases associated with hypoxia.

Effect of Exogenous Ketosis During Ultra-endurance Exercise

ExerciseUltra-endurance Running3 more

The aim of this study is to investigate the effect of oral ketone administration during and immediately after an ultramarathon. Potential changes in cognitive function (reaction time, number of errors), running performance, jump height, skeletal muscle inflammatory infiltration and hormonal alterations will be the main focus. In this context, subjects (n=24) will perform a 100km ultrarunning trail, while receiving either ketone ester (KE, n =12) or placebo (CON, n=12). Experimental measurements will be performed immediately before and after the ultramarathon as well as 24h after the ultramarathon.

Acute Effect of Exogenous Ketosis on Sleep Architecture Following Strenuous Exercise

Sleep

The aim of this study is to investigate the effect of oral ketone ester administration on sleep architecture. To investigate this, the investigators use a randomised, placebo-controlled, cross-over research design. The study comprises three experimental sessions, each separated by a one-week washout period. Two of the three experimental sessions consist of a 120 minutes cycling endurance training session (ET) two hours after breakfast and an evening high-intensity-interval training (HIIT) ending one hour before bedtime. After each training session, and 30 minutes before sleeptime, subjects receive a ketone ester or a control drink . To investigate the effects of strenuous exercise on sleep alone, an additional experimental session without exercise is added. Before bedtime, a venous blood sample is taken to evaluate hormones playing an important role in sleep regulation. During the experimental sessions, the subjects sleep in a sleep facility to evaluate quality of sleep. Time spent in different sleep phases is measured via polysomnography (PSG). Urine output throughout the day and night will be collected for measurement of urinary excretion of adrenaline and noradrenaline as an index of intrinsic sympathetic activity.

Role of Intermittent Exogenous Ketosis in the Physiological and Muscular Adaptive Response to Endurance...

Exercise Adaptations

In a recent study (Poffé et al., 2019), we demonstrated that increasing the concentration of ketone bodies in the blood through the ingestion of a ketone ester (KE) post-exercise and just before sleeping time during a 3-week overtraining period resulted in suppression of the physiological symptoms of overtraining. Consistent KE intake improved endurance performance, positively affected the autonomic regulation of the heart, suppressed the increase of nocturnal sympathetic activity, and increased spontaneous energy intake. In addition, KE intake had a positive effect on muscular adaptive response, as evidenced by the significantly increased muscular angiogenesis. Therefore, in this study, we aim to investigate whether the oral administration of ketones after exercise and just before bedtime also has a positive effect on the adaptive response during a well-dosed endurance training program. Since suppression of nocturnal sympathetic activity can positively influence sleep quality, we will also study the effect of KE and the training period on sleep quality. To investigate this, we will use a randomized, placebo-controlled parallel research design. Well-trained male cyclists will participate in a fully controlled intervention period of 8 weeks. During the intervention period, participants will follow a supervised cycling training program (5-7 training sessions per week) with a gradual buildup aimed at improving endurance capacity. Throughout the intervention period, participants will ingest 25g ketone ester or a corresponding placebo after each training session and 30 minutes before bedtime. Endurance performance will be evaluated before the start of the training period (pretest), after week 3 (midtest), after week 7 (posttest) of the training period, and at the end of the training intervention (posttest+taper). Additionally, blood samples will be taken at the pre-test and post-test to analyze markers of hormonal status and inflammation. Muscle biopsies will be taken from the vastus lateralis muscle of the right leg at pretest and posttest to analyze cross-sectional area, muscle fiber typing, angiogenesis, protein synthesis and degradation, mitochondrial function, and energy substrate concentrations. One month after the intervention period, an additional biopsy will be taken to study changes in gene expression (epigenetic modifications). Sleep will be evaluated via polysomnography (PSG) at the pretest, midtest and posttest. Finally, before and after the training period, resting and exercise echocardiography will be taken to investigate investigate structural and morphological changes of the heart.

Double Blinded Randomized Control Trial of Types of IVF in Children With DKA

Diabetic Ketoacidosis

Objectives: Intravenous (IV) fluid administration is a fundamental component of diabetic ketoacidosis (DKA) treatment. Normal saline (NS), the most common IV fluid used in DKA management, contains more chloride than human blood. Excessive amounts of chloride have been shown to cause a detrimental metabolic acidosis. Other IV fluids have more physiologic chloride levels, such as lactated ringers (LR). This study will compare the rates of hyperchloremic metabolic acidosis in children treated with NS to those treated with LR to determine the effect on overall length of acidosis and length of stay in the hospital or intensive care unit. Design: Single-center, double blinded, randomized controlled trial. Subjects: Children aged 0 to 18 years who present with diabetic ketoacidosis and require pediatric intensive care unit admission. Patients with evidence of shock, multi-organ failure or clinically significant cerebral edema will be excluded. The projected study population will be 104 patients, 52 in each arm. Interventions: Patients will be enrolled within 1 hour of presentation to the emergency room or pediatric intensive care unit if transferred directly from another facility. They will be randomized to receive intravenous fluids containing 0.9% saline or lactated ringers. All patients will be treated using the institutional DKA protocol with the content of the intravenous fluids being the only difference in treatment between arms. Study intervention lasts until the end of the acute management of DKA. Planned measurements and study outcomes: The primary study outcome will be duration of metabolic acidosis. Resolution of metabolic acidosis will be defined in three ways: 1. Normalization of the ketosis; 2. Normalization of the serum pH; 3. Normalization of the serum bicarbonate level. Secondary outcomes will include length of stay in the pediatric intensive care unit and length of stay in the hospital. All outcomes will be correlated with the overall chloride load given via intravenous fluids during DKA management. Regression modelling will control for any baseline differences between the groups in regards to severity of DKA, and if newly diagnosed or poorly controlled diabetes mellitus.
