This study aims to examine the acute effects of a low-volume bilateral pogo jump protocol on CMJ and DJ performance, as well as its feasibility and immediate tolerance in adolescent male basketball players.

The main objective of this research will be to investigate whether the control of care provided by the family/caregiver can prevent the incidence of delirium in individuals undergoing surgical intervention for hip fracture. The research will be a randomized, single-blind, parallel, two-arm clinical trial that compares two conditions: intervention group, hereafter IG (Delirium Zero protocol based on a space-temporal orientation poster for the patient, a clock hung on the wall next to the orientation poster, and a checklist for the preventive measures taken by the caregiver/family), and control group, hereafter CG (standard of care). The participants will be patients over 65 years old, admitted to the trauma hospitalization units at the La Fe University and Polytechnic Hospital (La Fe Health Department, Valencia, Spain) and at the Manises Hospital (Manises Health Department, Spain), who have had hip fracture surgery and are accompanied by a family member/caregiver. The research will take place in these centers because the rooms are private, which allows there to be no interference between the intervention under study (in the IG) or the standard care (CG).

Anterior cruciate ligament (ACL) injuries represent a highly relevant issue in both grassroots and professional sports, with a particularly high incidence in young and female populations. The objective of this project is to develop and validate a multiscale predictive algorithm for ACL injury risk in athletes from Villarreal CF (aged 10-45), integrating biomechanical, physiological, genetic, and gut microbiome biomarkers. The study, with a prospective and longitudinal design (4 years), will include a cohort of 200-250 players from the academy and first team. The following assessments will be conducted: biomechanical analysis of jumps using force platforms (instrumented LESS), physiological monitoring through resting heart rate and nocturnal heart rate variability (HRV), genotyping from saliva samples, and characterization of the gut microbiome 16 rRNA sequencing. The systematic recording of training, exposures, and injuries will follow OSTRC criteria and will be supervised by the club's medical team. The expected outcome is a multivariate predictive model, validated in a professional sports setting, capable of identifying individual risk profiles and generating a personalized score to guide preventive interventions (exercise, strength training, nutritional or probiotic strategies). This approach aims to reduce the incidence of ACL injuries, optimize performance, and translate biomedical knowledge into clinical and sports practice.

Patients with chronic kidney disease (CKD) undergoing hemodialysis present musculoskeletal complications, such as sarcopenia, which impair their functionality and are associated with an increased risk of mortality. Functional assessment in this population is complex due to the organization of hemodialysis schedules and patients' dependence on medical transportation, which hinders evaluation outside the dialysis setting. The assessment of lower limb strength is of great relevance, as an adequate level of muscle strength in this region is essential for performing many activities of daily living, including walking, sit-to-stand and stand-to-sit movements, as well as ascending and descending stairs. Our research group has published a study demonstrating the safety and reliability of intradialytic measurement of hip flexion and abduction strength; however, reference values for the dialysis population and for individuals with CKD in general are currently unknown. The primary aim of this study is to propose reference values for hip flexor and abductor muscle strength measured using a hand-held dynamometer in individuals with chronic kidney disease (CKD). Secondary objectives include assessing the association between lower limb muscle strength measured with a hand-held dynamometer and handgrip strength, physical activity level, frailty, gait speed, performance in the 10-repetition sit-to-stand-to-sit test, ultrasound assessment of the rectus femoris muscle, and health-related quality of life.

This study evaluates the effectiveness of a 3-month video-based lifestyle intervention, focused on promoting healthy lifestyle habits (healthy eating and increased physical activity), on adults with type 2 diabetes mellitus (DM2). Participants will be randomly allocated to receive the intervention either delivered by their own physician (experimental group) or by a physician unknown to them (control group). Assessment will include sociodemographic variables, glycated hemoglobin / HbA1c (primary outcome), body mass index, blood pressure, glycemic and lipid metabolism variables, physical activity level, adherence to the Mediterranean diet, therapeutic alliance, and health-related quality of life. The randomization process will be stratified according to HbA1c, therapeutic alliance, age, and sex.

Fear of childbirth ranges from mild worry to severe anxiety and affects women of all ages. It is often linked to perceiving childbirth as unpredictable and painful. Women cope by seeking support, practicing relaxation, or attending prenatal education, with information playing a key role in reducing anxiety and increasing confidence. Pain neuroscience education has shown benefits in reducing pain, anxiety, and related fears by teaching the neurobiological mechanisms underlying pain.

Background This study is part of a doctoral research project at Universidad Cardenal Herrera CEU (Spain), directed by Prof. Santiago Arias de Luxán and conducted by doctoral candidate Shirli Kelmendi within the PhD program in Translational Medicine. Fixed orthodontic appliances complicate oral hygiene by creating retention areas that favor bacterial colonization and alter microbial balance. These conditions increase plaque accumulation and Streptococcus mutans (S. mutans) proliferation in saliva and plaque. The frequent low-pH environment favors aciduric bacteria such as S. mutans and lactobacilli, promoting enamel demineralization and formation of white spot lesions (WSLs) or cavitations. WSLs appear as opaque white areas due to subsurface mineral loss, mainly in the gingival third of the crown. They may develop as early as one month after bracket placement, while in patients without appliances, progression occurs after at least six months. Increased S. mutans levels have been reported as early as six weeks after treatment start. Risk factors include poor brushing, lack of floss or rinse use, time since last cleaning, and presence of caries or lesions. Intervention MI Paste Plus (GC, Japan) is a remineralizing cream with 0.20% sodium fluoride (900 ppm) and 10% CPP-ACP (RECALDENT™), providing calcium and phosphate stabilized by casein phosphopeptides. It has antibacterial and remineralizing effects, suitable during or after orthodontic treatment to prevent or reduce WSLs. Objective To evaluate whether MI Paste Plus during fixed orthodontic treatment reduces S. mutans counts in saliva and/or WSL incidence. Study Design A prospective, triple-blind, randomized clinical trial, approved by the Ethics Committee of the Ministry of Health of Albania and the Ethics Committee for Human Research of Universidad Cardenal Herrera CEU, Spain. The study will include 200 patients (100 per group) from two orthodontic clinics in Tirana, Albania. Participants will be stratified by age, risk level, and appliance type, then randomized by third parties. Outcome Measures Primary variables: S. mutans counts in saliva and number of WSLs after 3 months. Standardized saliva collection, culturing, and bacterial quantification ensure consistency. Clinical assessments will be performed at 1 and 3 months using QRay Cam Pro (Inspektor Systems, Netherlands) for quantitative fluorescence and ICDAS for visual inspection. Data will be analyzed using SPSS/R Commander software.

This study aims to compare carotid intima-media thickness (CIMT) and layer-specific texture characteristics of the carotid wall between individuals with Type 2 diabetes mellitus (T2DM) and normoglycemic controls, to assess the impact of T2DM on these ultrasound variables and evaluate their ability to discriminate between low and high cardiovascular risk at 10 years.

Echointensity and echotexture have been used as a physiological marker for changes in skeletal muscle quality and structure caused by physical training, low activity, ageing and some neuromuscular disorders. However, there are some influencing factors on muscle echo-intensity and echotexture, such as temperature, which may not be taken into account when performing an ultrasound assessment and may alter the results. This study aims to investigate the effects of muscle temperature on echointensity and other 2nd order echotextures variables such as homogeneity, contrast, correlation and entropy of muscle tissue, in order to gain a better understanding of this correlation and minimise its influence, which would allow greater precision in the use of muscle ultrasound as a diagnostic tool. The methodology of this study includes firstly the acquisition of ultrasound images of the vastus lateralis muscle. This acquisition will be performed during the continuous recording of muscle temperature, carried out during a passive cooling process after 20 min of heating using microwave equipment. In addition, to standardise the results, a correction factor will be calculated to compensate for the influence of subcutaneous adipose tissue thickness on echogenicity and echotexture.

Chronic kidney disease (CKD) is the progressive damage to kidney function, associated with an increased risk of cardiovascular diseases, such as stroke or myocardial infarct, particularly in the most severe stages of CKD, in which the patient requires dialysis. Several risk factors are reported for CKD, such as diabetes mellitus, obesity and hypertension. One of the most increasingly recognized risk factors is the fat tissue malfunction, known as adiposopathy. The accumulation of fat tissue around the organs in conditions of obesity or diabetes accelerates the production of pro-inflammatory factors that may worsen the kidney and heart damage. New antidiabetic medications, such as glucagon-like peptide-1 receptor agonists (GLP-1RA), have proven beneficial effects on the kidney and heart due to several mechanisms, including anti-inflammatory actions and a potential action on the fat tissue. The aim of this study is to assess the link between adiposopathy and CKD, by investigating the changes in adiposopathy measures throughout treatment with GLP-1RA to a sample of patients with CKD.

The primary aim of this randomized controlled trial is to determine the efficacy of a 6-week immersive virtual reality (IVR)-based therapeutic exercise intervention, which manipulates visual proprioceptive input during exercise, for patients diagnosed with fibromyalgia (FM). Participants will be randomly allocated into two groups: an experimental group performing therapeutic exercises integrated with IVR featuring modified visual feedback, and a control group executing identical exercises without IVR integration. The primary outcome will assess the impact of fibromyalgia on daily activities, while secondary outcomes will comprehensively evaluate fatigue, sleep quality, severity of fibromyalgia symptoms, health-related quality of life, anxiety and depressive symptoms, fear-avoidance beliefs, pain catastrophizing, kinesiophobia, indicators of central sensitization, lumbar spine flexion and extension range of motion, somatosensory function, body perception distortion, muscle strength of the handgrip and quadriceps, functional mobility, lower limb strength, behavioral regulation concerning exercise adherence, and patient-reported experiences regarding IVR use. This trial seeks to elucidate whether incorporating IVR into therapeutic exercise protocols reduces the impact of fibromyalgia on patients' daily lives and improves physiological, psychological, and physical outcomes compared to traditional exercise approaches without IVR.

Black stains on the teeth, caused by the accumulation of chromogenic microorganisms that produce iron compounds, are more common in the pediatric population and have a negative impact on dental aesthetics and patients' self-esteem. The etiology of these stains remains unclear and is not related to oral hygiene. Currently, there is no definitive treatment that prevents the reappearance of these stains, and they can only be removed by mechanical removal, which can cause injuries to the tooth structure. This study aims to evaluate the effectiveness of erythritol powder air polishers, which have antimicrobial properties, compared to conventional prophylaxis in preventing the recurrence of stains. A randomized clinical trial will be carried out with a follow-up of 12 months, during which patient satisfaction and duration of treatment will be assessed. The results of this study could provide valuable information to improve treatment and management strategies for dental stains in the affected population, thus contributing to the emotional well-being of patients and reducing damage to their tooth enamel.

The purpose of the following study is to analyze the effects of a prehabilitation program based on therapeutic exercise, back care education and pain neuroscience education through the visualization of videos, compared to standardized written therapeutic exercise in patients undergoing lumbar radiculopathy surgery.

The main objective of this study is to assess the effects of a myofascial release protocol in patients with chronic obstructive pulmonary disease (COPD).

Introduction: Advances in neonatology mean a significant reduction in mortality in premature infants as well as an increase in the risk of morbidity in the medium, short and long term. Furthermore, previous studies have linked prematurity, as an associated risk factor, with possible alterations in the bonding between the child and his or her mother in the first years of life. The possible impact that the stay in the neonatal unit may have on the mental health of the parents is noted. In fact, several studies have shown that the hospital environment of neonatal units may contribute to increased stress and anxiety in mothers. On the other hand, prematurity is one of the causes of referral to Child Development and Early Care Centres, to address their development in the first years of life, as well as for family support. One of the functions of early childhood professionals is to guarantee the development of a secure attachment between the child and his or her caregivers. Little is known about whether maternal stress levels can influence mother-child interactions and thus influence the attachment relationship in the early years of life. Objective: to analyse the association between mothers' stress level due to preterm birth and attendance at a Child Development and Early Care Centre and child development and patterns of mother-child interactions.

According to the WHO, 280 million people are diagnosed with depression, the prevalence of which is almost twice as high in women as in men, with the incidence among young people increasing in recent years. Another public health problem in Spain is tobacco consumption, with one in four adults being tobacco users. The presence of an addiction and another mental illness in the same patient is called dual disorder, and it is very common for depression to be associated with smoking. This is due to a shared biopsychosocial vulnerability between the two disorders. Although there are currently pharmacological treatments that address both disorders, their efficacy is limited; in this sense, transcranial magnetic stimulation (TMS) offers a way to treat these dual disorders. TMS is a technique in which a magnetic field is applied to the cortex through a coil, generating an electric current that can induce changes in the different neurotransmitter systems, stimulating or inhibiting them. A randomised, double-blind, placebo-controlled clinical trial is proposed to evaluate the efficacy of TMS in the treatment of a sample of 36 patients with resistant major depression and nicotine dependence. Both depression and smoking will be assessed at baseline, at various times during treatment and at the end of the study using psychometric tests, neurophysiological and biochemical assessments. It is expected that the experimental group will show improvements in depression, nicotine dependence and certain cognitive functions. TMS treatment of dual disorders (resistant depression + smoking) could represent a health and social advance, especially for women.

The main objective of this investigation is to assess if an intradialysis virtual reality exercise program during the last two hours of the hemodialysis session results in greater hemodynamic stability than exercise performed during the first two hours of the hemodialysis session. The secondary aims are to assess the impact of intradialysis virtual reality exercise during the last two hours of the hemodialysis session on dialysis efficacy, postdialysis molecules rebound, adherence to exercise, functional capacity, physical activity level, health-related quality of life, cognitive function, morbidity, frailty and dependency. We will also analyze the reliability of muscle strength assessment of lower limb muscles with a handheld dynamometer during hemodialysis.

Pain is one of the most common symptoms among patients with End Stage Renal Disease (ESRD), and often goes unrecognized or inadequately managed in hemodialysis patients. More than 50% of patients undergoing hemodialysis suffer from pain, with 75% of them being treated ineffectively due to healthcare professionals\' lack of awareness of this symptom. Therefore, pain management in this population is a complex and challenging task for healthcare providers. The most prevalent pain syndromes in hemodialysis patients include musculoskeletal disorders, metabolic neuropathies, in addition to typical intradialytic pain. The aim of this study is to assess the presence and characteristics of chronic pain in patients with ESRD undergoing hemodialysis to determine whether it is relevant to include the management of chronic pain in the holistic treatment (physical activity, nutrition, and psychological support) already being implemented in various studies for these patients.
