Clinical trials

The GINGER-BLEED study is a randomized, double-blind, placebo-controlled clinical trial evaluating the effect of ginger powder on heavy menstrual bleeding in women with coagulopathies. This type of bleeding, defined as a loss of more than 80 ml per cycle, significantly affects women's quality of life, causing anemia, pain, and social limitations. Although conventional treatments exist, they can cause adverse effects, especially in women with coagulation disorders. The hypothesis is that administering 750 mg of ginger daily for six months can reduce menstrual bleeding. The main objective is to analyze this effect, while specific objectives include evaluating changes in coagulation parameters and prostaglandin levels. The study will be conducted between March 2028 and January 2029 at the University of Valladolid. Seventy-four women with coagulopathies, selected after a gynecological evaluation, ultrasound, and blood tests, will participate. They will be divided into two groups: one will receive ginger capsules and the other a placebo (Stevia) during the first three days of each menstrual cycle for six consecutive cycles. The PBAT tool will be used to estimate bleeding, and statistical analyses will be performed using SPSS v29. Variables such as adverse effects, treatment adherence, and clinical parameters will be considered. The study complies with current ethical standards, including the Declaration of Helsinki and Spanish data protection legislation. The results will be disseminated in scientific journals and patient associations, proposing improvements in public health policies.

The trial is designed to determine the added effect of active transcranial direct current stimulation (tDCS) when combined with a multimodal Active Pain Coping Program in individuals with fibromyalgia. The primary objective is to compare the effectiveness of active versus sham tDCS when both are delivered to the same standardized multimodal intervention. All participants will undergo an identical treatment sequence consisting of 8 sessions of Pain Neuroscience Education (PNE), followed by 5 consecutive daily sessions of either active or sham tDCS, and 18 sessions of therapeutic exercise (TE). Active tDCS will be administered over the primary motor cortex (M1) and orbitofrontal region for 20 minutes at 2 mA. The sham procedure will replicate the electrode placement and brief initial stimulation to ensure blinding, with no active current thereafter. Secondary outcomes will examine changes in pain intensity, central pain processing, psychological variables, and physical function.

Introduction: Breast cancer (BC) remains the leading cause of cancer in women with nearly 1.4 million new cases worldwide annually and 27.000 in Spain. Increasingly effective oncology therapies, however, have numerous adverse effects such as muscle degeneration, fatigue, decreased physical function and aerobic capacity, and deteriorating quality of life. In this sense, physical activity (PA) seems to be an interesting non-pharmacological strategy to alleviate these serious complications and with potential benefits for women with BC. Melatonin (N-acetyl-5 methoxytryptamine) is an indolic compound present with pleiotropic bioactions that regulates the circadian rhythm, antioxidant, anti-inflammatory, immunostimulant, cardioprotective, antidiabetic, antiobesity, neuroprotective, and antiaging actions. Furthermore, in recent years, many studies have described the key role of melatonin in preventing and developing cancer. The general anticarcinogenic mechanisms include epigenetic control, cell proliferation modulation, cell cycle regulation, apoptosis induction, and telomerase inhibition. Melatonin also exerts antiestrogenic activity, which is particularly significant in hormone-dependent tumors, regulating the expression and transactivation of the estrogen receptor, and modulating the enzymes involved in the local synthesis of estrogens. Despite all the mentioned properties, the use of melatonin in daily clinical practice is very limited, and additional studies are needed to better establish the role of this hormone in oncological clinical applications against different types of cancer. Objective: To analyze the effect of supplementation with 4 g/day of melatonin for 10 weeks on muscle damage (CK and LDH), hormonal responses (estradiol, testosterone, cortisol and testosterone/cortisol ratio), antioxidant capacity (BAP and d-ROMs), Exerkins (Irisin and Sestrin 2), physical performance (handgrip strength, RPE and SPPB), anthropometry (body mass, BMI and fat mass) and WHOQOL-BREF (physical and psychological health, social relationships and environment) in women over 60 years of age who have suffered breast cancer and who follow a physical training program. Methods: A total of 20 female volunteers between 60 and 73 years old (age: 65.5±4.52 years, BMI: 25.83±2.67 and body fat percentage: 33.73±5.54) who followed a physical activity adapted to their age and abilities are the members. of this study. The volunteers were divided into two groups: placebo (CG; n = 10) and supplemented with 5 g/day of melatonin (GI; n = 10). Differtent test were performed muscle damage (CK, and LDH), hormonal responses (estradiol, testosterone, cortisol, and testosterone/cortisol ratio), antioxidant capacity (BAP and d-ROMs), Exerkins (Irisin and Sestrin 2), physical performance (Hand-grip strength, RPE and SPPB), anthropometrics (Body mass, BMI and fat mass), and WHOQOL-BREF (physical and psychological health, social relationships and environment) were analyzed at the beginning (T1) and at the end of the 10 weeks of intervention (T2).

This randomized controlled trial aims to analyze the effects of anodal tDCS applied over the primary motor cortex and dorsolateral prefrontal cortex combined with a tele-rehabilitation exercise program in patients with fibromyalgia. The study will compare these effects with each other and with placebo tDCS on the following variables: pain intensity, pain mechanosensitivity, quality of life, fatigue, anxiety, depression, sleep quality, pain catastrophizing, functional capacity, isometric strength, and exercise adherence. Secondary objectives include: * Describing the sociodemographic, clinical, and functional characteristics of fibromyalgia patients. * Comparing exercise intensity levels between patients receiving tDCS on M1, DLPFC, and placebo stimulation. * Reporting any adverse effects of the intervention. Adult participants with fibromyalgia will be randomized into three groups: a) anodal tDCS over M1 + telerehabilitation, b) anodal tDCS over DLPFC + telerehabilitation, and c) sham-tDCS + telerehabilitation. The intervention will last for 12 weeks. The telerehabilitation exercise program will include an aerobic phase and a resistance phase, with four intensity levels regulated based on the Borg Rating of Perceived Exertion (0-10). The program will be conducted remotely through phone contact, with materials and videos provided to guide exercise execution. tDCS will be applied once per week for 20 minutes at 2 mA, either over M1 or DLPFC. The dependent variables-pain intensity, fibromyalgia impact, fatigue, anxiety and depression levels, pain catastrophizing, sleep quality, functional capacity, and isometric muscle strength-will be collected in the week prior to the intervention, the week following the intervention, and 12 weeks after its completion. Additionally, pain intensity, fibromyalgia impact, fatigue severity, anxiety and depression levels, pain catastrophizing, and sleep quality will be evaluated during the 6th week of the intervention. Exercise intensity, exercise adherence, and any adverse effects related to the intervention will be recorded weekly.

The aim of this observational study is to validate the content of a tailored ICF core set for the management of musculoskeletal conditions in primary care physiotherapy services. The main question it aims to answer is: \- Are the ICF entities included in the ICF Core Set under evaluation useful from a clinical point of view? Participants will evaluate the relevance of each ICF entity included in the ICF core set according to their musculoskeletal condition.
