NCT06721897
We live in an increasingly aging society in which the incidence of osteoarticular diseases increases, among which osteoarthritis (OA) stands out. OA is a degenerative disorder of the different components of the joint leading to a progressive destruction of the same. The hip and knee being the most affected joints, OA presents multiple symptoms such as pain, stiffness and functional limitation, also causing psychological disorders such as anxiety, depression, quality of sleep and poor perception of quality of life. Conventional treatment is aimed at alleviating symptoms, but when conservative therapies fail in the more advanced stages of the disease, total joint replacement surgery or arthroplasty is the therapeutic option of choice. Strength physical exercise (PE) and aerobic training have been shown to be effective in OA, obtaining positive effects on the symptoms and on variables that deteriorate this disease. The concept of pre-habilitation or preoperative rehabilitation has been shown through other studies in different pathologies (cardiopulmonary and musculoskeletal) to have positive effects at a clinical and functional level, however, the planning of a pre-habilitation protocol in hip or knee arthroplasty is still controversial. The purpose of this study is to determine the effect that a prehabilitation program will produce and its possible usefulness in those subjects who are waiting for a hip or knee arthroplasty. It is expected to find favorable results that support this therapy when it comes to reducing postoperative recovery times, functional capacity and other psychological variables of interest. This powerful tool could represent a non-pharmacological and non-invasive therapy, as well as being useful and economical in the management of patients with OA in advanced stages.
NCT05412381
The purpose of our study is to examine the effect of platelet-rich-plasma (PRP) injection on the short-term resolution of post-injury inflammation (biomarkers) and improvement in joint function in patients with acute ACL injury. This RCT has been powered based on the questionnaire KOOS Jr. but it is considered a 'pilot study' in terms of the lab analysis proposed.
NCT07408895
This study evaluated the effect of injectable platelet-rich derivatives on the rate of orthodontic canine retraction. Patients requiring orthodontic canine retraction following premolar extraction were enrolled and divided into three groups using a split-mouth design. Injectable platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) were applied to compare their effects on the rate of tooth movement. The outcomes were assessed by measuring the amount of canine retraction over time.
NCT07409467
This prospective observational study aims to develop and evaluate predictive models for postoperative complications in patients aged 65 years or older scheduled for elective major surgery. The investigators will recruit 520 eligible patients visiting the preoperative assessment clinic. The study involves the prospective collection of comprehensive preoperative data using specific validated tools: * Physical Activity: Assessed using the Saltin-Grimby Physical Activity Scale (SGPAS) to categorize physical activity intensity. * Nutritional Risk: Screened using the Nutritional Risk Screening 2002 (NRS-2002) tool. * Psychological Status: Evaluated for anxiety and depression using the Hospital Anxiety and Depression Scale (HADS). * Body Composition: Measured using a portable bioelectrical impedance analysis (BIA) device (BWA2.0S, InBody) to assess muscle mass, body fat/water, and phase angle. * Physical Function: Assessed via the short physical performance battery (SPPB) using electronic measurement devices (AndanteFit, DYPHI) to calculate frailty index and physical age. The primary endpoint is the occurrence and severity of postoperative complications within 30 days, evaluated using both the Clavien-Dindo Classification and the Comprehensive Complication Index (CCI). Using the collected dataset, the investigators will develop prediction models using both classical regression analysis and machine learning algorithms to compare their predictive performance.
NCT07410663
This retrospective, controlled clinical study aims to evaluate the effectiveness of a targeted biological support injection containing a hyaluronic acid and amino acid combination in patients with chronic lateral epicondylitis (tennis elbow). Medical records will be reviewed to compare outcomes between patients treated in routine clinical practice with a 3-dose injection regimen (weeks 0, 2, and 4) plus a home exercise program and those treated with a home exercise program alone. Key outcome measures include pain intensity (VAS), functional status (PRTEE), grip strength, and pressure pain threshold.
NCT07411079
Intracerebral hemorrhage (ICH) is associated with high mortality and long-term disability, and effective treatment options remain limited. Minimally invasive surgical approaches combined with local administration of thrombolytic agents have been investigated to facilitate hematoma evacuation; however, incomplete clot removal remains frequent, particularly in patients with conditions associated with increased hemorrhagic risk. This observational, cross-sectional study uses an ex vivo model of clinically sized intracerebral hematomas generated from whole blood samples collected from control subjects without hemorrhagic risk and from individuals with predefined hemorrhagic risk profiles, including conditions associated with antithrombotic treatment, inherited bleeding disorders, thrombocytopenia and situations involving reversal or correction of coagulation abnormalities. Using standardized ex vivo hematoma formation and catheter-based administration of modified Tissue Plasminogen Activator (rtPA), the study will characterize clot structure, composition, and permeability across hemorrhagic risk conditions. The study will then determine personalized dosing regimens of modified rtPA in conditions where thrombolytic activity differs from reference values observed in healthy control samples treated with a standard dose. Finally, the thrombolytic activity of personalized dosing regimens will be evaluated by measuring hematoma weight reduction 9 hours after treatment and compared with predefined efficacy and safety reference boundaries. The results of this study are intended to improve understanding of the ex vivo thrombolytic performance of modified rtPA across different hemorrhagic risk contexts and to support future translational and clinical research in intracerebral hemorrhage.

The goal of Part 1 of this clinical research study is to find the highest tolerable dose of ASTX029 that can be given in combination with ASTX727 to participants who have RAS-mutant MDS or MDS/MPN. The goal of Part 2 of this clinical research study is to learn if the dose of ASTX029 found in Part 1 can help to control the disease when used in combination with ASTX727.
NCT07408570
Exposure to microgravity leads to pronounced impairments in neuromuscular control, postural stability, and spinal reflex regulation that cannot be attributed to muscle atrophy alone. Rather, these deficits point to a disruption of load-dependent sensorimotor mechanisms and highlight the essential role of gravitational loading of the skeleton as a critical source of sensory input for spinal motor control. Spinal reflex behavior during upright stance has traditionally been explained primarily by muscle spindle-mediated pathways. However, this framework does not fully account for the reflex alterations observed under conditions of altered mechanical loading, including microgravity, prolonged unloading, or exposure to vibration. In parallel, advances in bone biology have identified osteocytes within the lacuno-canalicular system as highly sensitive mechanosensors that preferentially respond to dynamic loading and changes in strain rate. This insight has given rise to the concept of bone myoregulation, in which bone-derived mechanosensory signals contribute to the modulation of spinal excitability. A defining characteristic of this process is the poroelastic nature of bone tissue. As a fluid-saturated porous medium, bone exhibits frequency-dependent mechanical behavior, such that oscillatory loading modifies both the temporal profile and magnitude of interstitial fluid flow within the lacuno-canalicular network. As a result, loading frequency is expected to influence not only the timing of reflex responses but also their amplitude. Whole-body vibration offers a controlled experimental paradigm to probe these frequency-dependent, load-sensitive mechanisms in humans. Accordingly, the aim of the present study was to identify the whole-body vibration frequency band that most effectively induces soleus reflex responses during quiet standing, considering both reflex latency and response amplitude. Investigators hypothesized that these responses would display frequency-dependent behavior consistent with poroelastic bone-mediated myoregulation and would be modulated by individual anthropometric characteristics, with potential implications for vibration-based countermeasures under altered gravitational loading.
NCT07408271
This clinical controlled study enrolled 73 H. pylori(Helicobacter Pylori )-infected female participants, stratified into reproductive-age and menopausal cohorts, alongside 10 non-infected controls. Through integrated analysis of routine vaginal discharge parameters and longitudinal amplicon sequencing data of vaginal discharge, investigators analyzed the impact of H. pylori eradication therapy on vaginal microecology.
NCT04567680
Veterans with PTSD often have impaired social relationships and poor social support. The negative outcomes associated with poor social support are of particular concern for Veterans with PTSD, who often perceive the world to be dangerous, view their social support network as a threat to their safety, and avoid members of their support network in order to increase their perceived safety. The goal of this project is to evaluate the efficacy of Acceptance and Commitment Therapy to Improve Social Support for Veterans with PTSD (ACT-SS), a treatment focused on helping Veterans with PTSD to increase social support with family relationships, partners, and peers by targeting maladaptive patterns of interpersonal difficulties, feelings of detachment from others, irritability, and avoidance of social situations. The primary aim of this study is to conduct a two-site randomized controlled trial of ACT-SS (n=75) vs. PCT (n=75), a common treatment for social support difficulties. If positive, this study will provide a critically-needed treatment for Veterans with PTSD to improve their social functioning and social reintegration in the community.

NCT06354361
Goal Management Training (GMT) is a program designed to help improve cognitive functioning. For this study, researchers have worked closely with the developers of this program to create a modified version called Trauma-Informed Goal Management Training (TI-GMT), that is more sensitive to the needs of individuals experiencing symptoms of posttraumatic stress and posttraumatic stress disorder (PTSD). The goal of this clinical trial is to find out whether this modified, Trauma-Informed Goal Management Training program is effective for individuals experiencing symptoms associated with Post-Traumatic Stress Disorder. The main questions it aims to answer are: 1. Does Trauma-Informed Goal Management Training result in improved neuropsychological functioning and reductions in the severity of PTSD symptoms from baseline to post? 2. Does Trauma-Informed Goal Management Training result in self-reported improvements in cognitive functioning and the overall ability to function (including intent to return to work, and/or intent to stay at work, reductions in disability status, etc.) from baseline to post? 3. Does Trauma-Informed Goal Management Training continue to benefit individuals three months after treatment? Participants will: * complete three separate assessments before starting the treatment - a clinical interview to evaluate symptoms, a cognitive assessment, and completing a set of questionnaires * participate in a nine-week group treatment program (one day a week for two hours) * complete four separate assessments after completing the treatment - a clinical interview to evaluate symptoms, a cognitive assessment, a feedback interview, and completing a set of questionnaires * complete three separate assessments three months after completing the treatment - a clinical interview to evaluate symptoms, a cognitive assessment, and completing a set of questionnaires
NCT04316650
This research concerns the evaluation of the maintenance of the efficiency and incidence of adverse effects of pharmacological treatments in sex offenders with paraphilia. Despite the increasing use of pharmacological treatments in these indications, there are few data to indicate which sex offender populations benefit from which pharmacological treatments and which adverse events are observed, particularly with anti-androgens or antidepressant treatments that are widely used in these subjects. A recent Cochrane study showed that psychodynamic treatment is less effective in terms of sexual delinquency compared to probation alone and has not shown significant efficacy of cognitive behavioral therapy (CBT) compared to the lack of treatment, except for a study in which anti-androgen therapy was associated with CBT. Another recent study concluded that the tolerance, even of anti-androgenic drugs, was uncertain, as all studies were small and of limited duration, and new research is needed in the future. Further research demonstrating the efficacy of SSRIs in the treatment of paraphilic disorders is still needed and long-term studies are lacking. Their use for this indication is still off label. As far as we know, this cohort should be the largest population of paraphilic sex offenders studied for the longest time to date in a field where research is insufficient. This large sample receiving routine care and followed for 3 years should allow to analyse the maintenance of the effectiveness of the pharmacological treatments received (SSRIs or anti-androgens), and their tolerance. In addition, this analysis of clinical practices should be crucial to improve the knowledge of the indications for these treatments, which could possibly be reviewed with respect to their effectiveness and tolerance, especially in the most serious cases of paraphilic sex offenders.
NCT05383755
Pregnant adolescents living with HIV (ALHIV) in Kenya frequently experience stigma and difficulty telling a family member about their HIV and pregnancy status. This study will develop and evaluate a digital intervention for pregnant unmarried ALHIV to address the effects of stigma and strengthen communication skills. Family caregivers are an important yet underappreciated and understudied source of social support for pregnant unmarried ALHIV. The study will also identify acceptable approaches to involve family caregivers in addressing the detrimental effects of the intersecting stigmas faced by pregnant ALHIV. Together, these approaches are expected to improve engagement in PMTCT services among pregnant ALHIV. The study specific aims are to: (1) Develop and evaluate a digital intervention for pregnant unmarried ALHIV aged 15-19 to increase awareness of stigma and its consequences; improve disclosure self-efficacy and skills; and facilitate enlistment of family caregivers as social support allies to enhance uptake of PMTCT services; and (2) Identify acceptable approaches to increase awareness about stigma and enhance skills in communication and provision of social support among family caregivers. We will use data from individual interviews with pregnant ALHIV and joint interviews with pregnant ALHIV/caregiver dyads to develop initial intervention specifications and mock-ups. We will then conduct focus groups to obtain feedback on sample materials in order to refine the materials and develop an intervention prototype. We will then conduct a pilot to evaluate acceptability, usability, and preliminary efficacy of the prototype. All participating adolescents will receive a session in using the digital intervention with a mobile phone or tablet. The research team will ask questions both before the session and two weeks after the session in order to assess the intervention's usability and acceptability and preliminary improvements in the adolescents regarding stigma, disclosure, and social support. We will conduct focus groups with caregivers to identify acceptable approaches to involve them. Data will be used to finalize content and specifications of the digital intervention for pregnant ALHIV and will provide the framework for a future complementary intervention for caregivers, which will both be tested in a larger R34 or R01 trial.
NCT07405567
Patients with pneumonia who require invasive mechanical ventilation in the intensive care unit (ICU) often experience difficulties during the process of being separated from the breathing machine (weaning). Failure of weaning is associated with longer ventilation duration, prolonged ICU stay, and increased risk of complications and death. Therefore, simple and reliable bedside tools are needed to better understand respiratory muscle function and to help predict weaning outcomes. This prospective, observational, single-center study aims to evaluate respiratory muscle function using bedside ultrasound in adult ICU patients with pneumonia receiving invasive mechanical ventilation. The diaphragm, parasternal intercostal muscles, and anterior scalene muscles will be assessed using ultrasound during the weaning process. Measurements will be performed serially, starting from the first day when patients demonstrate meaningful spontaneous breathing effort and continuing until successful extubation, tracheostomy, or ICU mortality. Ultrasound measurements of muscle thickness and thickening fraction will be analyzed in relation to weaning outcomes. In addition, ventilator parameters and commonly used weaning indices will be recorded at the time of each ultrasound assessment. The findings of this study are expected to improve understanding of respiratory muscle involvement during weaning and may contribute to earlier identification of patients at risk of weaning failure.
