Low back pain (LBP) is the second cause of medical visits in France. Indeed, its incidence can vary between 60 and 90%. LBP is also the leading cause of disability in the adult population in France and in the rest of the world. Its evolution towards chronicity is observed in less than 8% of cases, but it is responsible for 85% of the medical costs. Degenerative disk disease (DDD) is a major cause of chronic LBP (\> 40%). DDD can be characterized by peculiar Magnetic Resonance Imaging (MRI) features with a strong correlation between pain and inflammatory aspect of the disk, which result in the so-called active discopathy (AD) (Brinjikji et al. 2015). Modic classification based on MRI of the lumbar spine is considered as a reference. Type 1 Modic signal changes are characterised by a low-intensity signal on T1-weighted sequences and hyperintense signal on T2-weighted sequences, with gadolinium injection enhancement, corresponding to bone marrow oedema. Type 1 Modic is very rare in an asymptomatic population but may be found in 5% to 40% of chronic LBP patients underscoring its symptomatic involvement. No currently reference treatment is available for AD. PRP technology has recently been widely developed in osteoarthritis and tendon injuries. Therapeutic benefit of PRP has being evaluated. For instance, no randomized controlled trials (RCTs) have specifically evaluated the effect of PRP in AD (Modic 1 signal). The availability of PRP for intra- discal injection could become an innovative therapeutic option in humans, especially for AD forms where inflammatory process is clearly predominant. The objective of the study is to evaluate the 3-month efficacy on pain and function (by achieving 30% improvement in Oswestry Disability Index) of one intra-discal PRP injection versus placebo (saline solution) in subjects with LBP associated with AD lasting more than 3 months.
NCT02944682
This study is a randomized controlled trial of liquefied petroleum gas (LPG) stove and fuel distribution in 3,200 households in four countries (India, Guatemala, Peru, and Rwanda). Following a common protocol, each intervention site will recruit 800 pregnant women (aged 18-34 years, 9 - \<20 weeks gestation) and will randomly assign half their households to receive LPG stoves and an 18-month supply of LPG. Control households are anticipated to continue to cook primarily with solid biomass fuels and will receive compensation based on a uniform set of trial-wide principles, customized to each site based on formative research. The mother will be followed along with her child until the child is 1 year old. The researchers estimate that 15% of households will have a second, non-pregnant older adult woman (aged 40 to \<80 years) who will also be enrolled at baseline and followed during the 18-month follow-up period. To optimize intervention use, the researchers will implement behavior change strategies informed by previous experiences and formative research in Year 1. This study will assess cookstove use, conduct repeated personal exposure assessments of household air pollution, and collect dried blood spots and urinary samples for biomarker analysis and biospecimen storage. The primary outcomes are low birth weight, severe pneumonia incidence, and stunting of the child, and systolic blood pressure in the older adult woman. Participants in India, Guatemala and Rwanda will be followed until the child is 5 years old to assess the longer-term effects of the intervention.

Blood cancers occur when the molecules that control normal cell growth are damaged. Many of these changes can be detected by directly examining parts of the cancer or cells in blood. Several alterations that occur repeatedly in certain types of blood cancers have already been identified, and these discoveries have led to the development of new drugs that target those alterations. More remain to be discovered. Some of these abnormalities include alterations in genes. Genes are the part of cells that contain the instructions which tell the investigators bodies how to grow and work, and determine physical characteristics such as hair and eye color. Genes are composed of DNA letters that spell out these instructions. Studies of the DNA molecules that make up the genes are called "molecular" analyses. Molecular analyses are ways of reading the DNA letters to identify errors in genes that may contribute to an increased risk of cancer or to the behavior of the cancer cells. Some changes in genes occur only in cancer cells. Others occur in the genes that are passed from parent to child. This research study will examine both kinds of genes. The best way to find these genes is to study large numbers of people. The investigators expect that as many 1000 individuals will enroll in this study. This research study is trying to help doctors and scientists understand why cancer occurs and to develop ways to better treat and prevent it. To participate in this study the participant must have cancer now, had it in the past, or are at risk of developing cancer. The participant will not undergo tests or procedures that are not required as part of their routine clinical care. The investigators will ask the participant to provide an additional sample from tissue that is obtained for their clinical care including blood, bone marrow, or tissue sample. The investigators will also ask for a gentle scrape of the inside of their cheek, mouthwash or a skin sample to obtain their germline DNA

Although breast cancer remains one of the most common and fatal cancer types among women worldwide, earlier diagnosis and improved therapeutic approaches have led to decreased mortality over last years. Indeed, the use of HER2-targeted drugs has improved clinical outcomes for patients with HER2 positive breast cancer, while, on the other hand, until recently, little progress has been made for HER2-negative (IHC score 0 and 1+) patients. However, it seems that among these HER2-negative breast cancers, substantial heterogeneity exists regarding the expression of hormone receptors (HR) and HER2. Biomarkers are critical for translating the biological heterogeneity of breast cancer into prognostically and therapeutically useful information. In recent years gene expression profiling and genomic analysis have shown utility in specific clinical scenarios, but immunohistochemistry (IHC) remains the cornerstone of biomarker testing in both early and advanced/metastatic disease. In breast cancer, achieving efficacy with endocrine therapy or with HER2-blockade requires identifying patients whose tumors show significant survival dependency on the therapeutic target. This is achieved by using appropriate biomarkers cut-offs ensuring a favorable benefit-to-toxicity ratio for specific patients. This paradigm has recently been challenged by a new class of HER2 drugs that use target expression not as a direct molecular lever but as a vehicle to deliver potent agents to cancer cells, breaking the straightforward link between the molecular target and the corresponding therapy. These drugs exhibit impressive activity at marker expression levels much lower than those required to effectively block HER2 signaling, shifting the diagnostic focus to the lower end of the staining spectrum, specifically distinguishing between HER2-zero and HER2-low expression. Given the lack of a definitive molecular hallmark for cancers characterized by low HER2 expression, ongoing efforts aim to understand the biology of this heterogeneous group of tumors. This understanding is crucial to triage treatment, investigate resistance mechanisms, and inform potential combination strategies. To enrich the available data, we perform a retrospective analysis of HER2-low patients in a large prospective cohort of early breast cancer patients from Greece enrolled in 7 randomized and observational clinical studies. The study is structured as follows: From each patient with early breast cancer, at least two 2.5mm wide cores are punched from donated FFPE blocks and transferred onto low-throughput TMAs. The cores are selected to enrich for regions with higher tumor nucleated cellularity to facilitate NGS analyses. Each core is assessed for biomarker expression with biomarker cutoffs applied at the core level. A case is considered positive for a biomarker if any of its cores tested positive at the predefined cut-off value. Cases showing any core with HER2 IHC 3+ and/or FISH amplification are excluded from this analysis. The remaining cases (n= 2751) are categorized into HER2-low and HER2-zero. The study aims to investigate whether HER2-low and HER2-zero cases exhibit distinct characteristics, suggesting HER2-low may represent a unique biological subtype. Given the importance of the hormone receptors and the known differential distribution of ER/PgR status between these two HER2 categories, after analyzing the entire population cohort, ER/PgR status will be treated as a confounding variable in the analysis (Luminal vs. TNBC) and the HER2 categories will be compared separately within ER/PR-pos (Luminal) and ER/PR-neg (TNBC) disease. To find out whether intra-tumor discordance of HER-2 is suggestive of true biological heterogeneity we will also consider for the analysis the different HER2 IHC scores between the available cores for each case as well as the distribution of ERBB2 CN data (median of ERBB2 avg copies).
NCT06821607
The investigators will conduct a prospective, randomized, clinical trial addressing key questions to understanding the effectiveness of telerehabilitation (physical therapy delivered via video-visits) and in-clinic physical therapy for patients with chronic low back pain (LBP). The investigators also seek to understand how patients engage with both care options and how these treatment options influence other LBP-related healthcare utilization. The investigators will explore implementation outcomes using a mixed methods approach consisting of electronic surveys and semi-structured interviews with patients, physical therapists, practice managers, and outpatient services administration focusing on perceived quality and impact on barriers to care. The investigators will enroll 1000 patients with chronic LBP seeking outpatient care at the healthcare systems in Maryland (Johns Hopkins Medicine (JHM)) and Utah (University of Utah (UU) and Intermountain Healthcare (IHC)). Eligible patients will provide informed consent and be randomized to receive telerehabilitation or in-clinic physical therapy delivered by a trained physical therapist. Primary effectiveness outcome is the difference in change in LBP-related disability (Oswestry Disability Index) after 8 weeks of treatment.
NCT07552766
This study is a prospective, randomized, double-blind clinical trial evaluating whether intraoperative intravenous lidocaine infusion (IVLI) reduces opioid requirements and improves postoperative pain control in children undergoing surgical fixation of upper extremity long bone fractures under general anesthesia. Ninety pediatric patients, ages 3-18 will be enrolled and randomized 1:1 to receive either IV lidocaine or placebo (normal saline) during surgery. All participants will receive standardized anesthesia care and postoperative pain management. Opioid consumption and pain scores will be measured intraoperatively and throughout the postoperative recovery, with the primary outcome focused on total opioid use 60 minutes after arrival to the post-anesthesia care unit (PACU). Secondary outcomes include opioid use at additional time points, postoperative pain scores, PACU length of stay, rescue antiemetic use and the relationship between infusion duration and outcomes. Patients will be closely monitored for signs of local anesthetic systemic toxicity and other adverse events. The goal of this study is to determine whether IV lidocaine is an effective opioid-sparing adjunct in pediatric orthopedic surgery and to support safer, multimodal analgesia strategies.
NCT03992404
The purpose of this study is to determine whether a single treatment with administration of 400 Units NT 201 (botulinum toxin) is superior to placebo (no medicine) for the treatment of lower limb spasticity caused by stroke or traumatic brain injury (Main Period). Participants will be assigned to the treatment groups by chance and neither the participants nor the research staff who interact with them will know the allocation. The following 4 to 5 treatment cycles will investigate the safety and tolerability of treatment with NT 201 (botulinum toxin) when administered in doses between 400 and 800 Units (Open Label Extension Period). All participants will receive the treatment and the dose will depend on whether only lower limb spasticity or combined upper and lower limb spasticity are treated.
NCT07543536
This study aims to evaluate whether the combination of Megestrol Acetate at the initiation of Trastuzumab Deruxtecan (T-DXd) treatment can effectively prevent and alleviate T-DXd-related fatigue, thereby improving the quality of life for advanced breast cancer patients.
NCT05345015
The purpose of this study is to examine the acute and chronic effects of high frequency electrical current transfer (frequently called "TECAR") on pain and functional movement in individuals with a musculoskeletal injury or pain. The participants will be assigned into an experimental or a control group and outcome measures will be measured prior to, after, 24 and 48 hours following a single intervention session (Acute effects) as well as 3 and 6 months after the intervention (chronic effects).
NCT05966636
Veterans who use prosthetic limbs commonly suffer from skin problems such as scars that create discomfort and pain to the point that wearing the prosthesis is no longer tolerable. The Veteran must then discontinue prosthetic use to allow healing prior to wearing the limb again. Current treatments for skin problems include manual scar mobilization and massage, stretching, desensitization techniques, pain medication, prosthetic adjustment, steroid injection, scar excision and others. Most of these have not proven to be a long-term solution. A dermatologic procedure common in non-amputees for scar and skin lesion management, fractionated laser therapy, may be a long-term solution minimizing discomfort, pain and time out of the prosthesis. This preliminary study seeks to determine if fractional laser therapy can improve prosthetic use, and quality of life of Veterans with amputation who use lower limb prostheses.
NCT05935761
Chronic pain symptoms are very common among U.S. Military Veterans and have a profound negative impact on mental health symptoms and quality of life, in addition to increasing risk for suicidal ideation and suicidal behaviors. There are currently extremely few safe and effective pharmacological treatments for chronic pain disorders, and the clinical need to develop new therapeutics for pain has never been more urgent. Fueled by the worsening opioid crisis and further exacerbated by the COVID-19 pandemic, opioid and other drug overdose deaths have climbed to staggeringly high levels. The rapid development of medications for the management of chronic pain conditions that are safe, well-tolerated, efficacious and non-addicting is thus of paramount importance. The two neurosteroid candidates to be investigated in this trial are naturally occurring molecules enriched in human brain and potentially ideal candidates for safe and effective chronic pain treatment.
NCT05986292
The purpose of the chronic pain master protocol is to compare independent pain interventions and establish an overarching structure for the disease-state addenda (DSA) and intervention-specific appendices (ISAs). The ISAs may start independently of other ISAs as interventions become available for clinical testing.
NCT06966700
Researchers are looking for new ways to treat types of breast cancer that are both: * High-risk, which means the cancer may have a higher chance of getting worse or coming back after treatment * Early-stage, which means the cancer is in the breast or the lymph nodes around the breast The 2 types of breast cancer in this study are triple-negative breast cancer (TNBC) and hormone receptor (HR)-low positive/human epidermal growth factor receptor-2 (HER2) negative breast cancer. These cancers have zero or a low amount of a protein called HER2 and other proteins that attach to the hormones estrogen or progesterone. Sacituzumab tirumotecan (also known as sac-TMT or MK-2870), the study medicine, is a type of targeted therapy. A targeted therapy is a treatment that works to control how specific types of cancer cells grow and spread. The main goals of this study are to learn if people who receive sac-TMT, pembrolizumab, and chemotherapy: * Have fewer cancer cells found in the tumors and lymph nodes removed during surgery compared to those who receive only pembrolizumab and chemotherapy * Live longer without the cancer growing, spreading, or coming back compared to people who receive only pembrolizumab with chemotherapy
NCT06661850
This study is looking into how safe and useful NOCISCAN is. NOCISCAN is a software as a Service (SaaS) tool that uses Magnetic Resonance (MR) spectroscopy. Nociscan (instead of 'It') leverages MRS to noninvasively help physicians distinguish between painful and nonpainful discs in the lumbar spine. The randomized controlled trial will compare the blinded and unblinded cohorts and their corresponding surgical outcomes with the Nocigram reports, generated prior to treatment, for each patient."
NCT07084740
The aim of reconstructive surgery is to restore physical integrity altered by trauma, congenital malformations or cancerous pathologies. Several techniques are available, including flap surgery, which enables tissue to be moved from one anatomical location to another. Perforating skin/subcutaneous flaps are segments of skin and subcutaneous cellular tissue vascularized by a feeder vascular pedicle. This surgical technique has virtually zero donor-site morbidity, as it is no longer necessary to harvest muscle to ensure reliable vascularization of the flap. Flap vascularization is a variable mechanism, complex to describe and understand. For cutaneous and subcutaneous (fatty) flaps, which account for the majority of flaps used, perforator flaps (vascularized by a subcutaneous perforator artery) have become the benchmark. Unfortunately, their vascularization is currently poorly understood, and depends on experimental work carried out on fresh cadaveric anatomical specimens. These cadaveric studies fail to take into account several key factors influencing perforasomes (perforasome: skin territory vascularized by a pedicle), namely body temperature, blood pressure, heart rate, intraoperative patient position and biological parameters.
NCT04576117
This phase III trial investigates the best dose of vinblastine in combination with selumetinib and the benefit of adding vinblastine to selumetinib compared to selumetinib alone in treating children and young adults with low-grade glioma (a common type of brain cancer) that has come back after prior treatment (recurrent) or does not respond to therapy (progressive). Selumetinib is a drug that works by blocking a protein that lets tumor cells grow without stopping. Vinblastine blocks cell growth by stopping cell division and may kill cancer cells. Giving selumetinib in combination with vinblastine may work better than selumetinib alone in treating recurrent or progressive low-grade glioma.
NCT07484997
The goal of this clinical trial is to learn if Concentrated Growth Factor (CGF) plugs help improve bone healing and reduce pain after the surgical removal of impacted lower third molars. The study aims to answer the following: Does packing CGF plugs into the extraction site improve bone density? Does the use of CGF plugs reduce postoperative pain for the patient? Researchers will evaluate the healing outcomes of patients receiving this treatment in a prospective case series study. Because this is a case series, all participants will receive the CGF plug intervention rather than being compared to a placebo group. Participants in this study will: Undergo a blood draw to create the autologous CGF plug from their own growth factors. Undergo the surgical extraction of an impacted lower third molar under local anesthesia. Have a CGF plug placed in the extraction socket immediately following the tooth removal. Report their pain levels using a numeric scale on Day 1, Day 3, and Day 7 after surgery. Return for a follow-up CBCT scan three months after the procedure to evaluate bone density changes.
NCT06518278
BACKGROUND: Chronic pain continues for more than 12 weeks despite medication or treatment. Chronic pain is the main symptom of muscle and joint problems, rarely explained by damage to the muscle and joints alone. Activity in the central nervous system (CNS; nerves, spinal cord, and brain) pathways governs our ability to describe pain intensity and our emotional response to pain. Musculoskeletal conditions (e.g., inflammatory arthritis, osteoarthritis, low back pain, fibromyalgia) share altered CNS pathways, acknowledged by recent classifications of 'primary' and 'nociplastic' pain. Clinically useful tools to diagnose and measure activity and reveal abnormalities in these CNS pathways are needed to improve clinical decisions and accelerate new treatment development. Laboratory pain sensitivity testing and brain imaging confirm the CNS as a primary contributor to pain. These assessments are less acceptable or unfeasible for clinical practice. Simpler clinical pain sensitivity assessments are being developed. The investigators simple Central Aspects of Pain (CAP) questionnaire detects some people with pain sensitivity and knee, rheumatoid arthritis or low back pain. Combining the CAP questionnaire reflecting emotional processing and simpler pain sensitivity assessment, combining two different dimensions should be better than either approach alone. PURPOSE: To optimise diagnosis and measurement of CNS as the primary contribution to chronic musculoskeletal pain by using the CAP questionnaire and simpler pain sensitivity assessments to ensure timely, effective diagnosis and treatment. OBJECTIVES: 1. Assess the ease, ability and performance of the combined CAP questionnaire and simpler pain sensitivity assessments to identify CNS as the primary contributor to chronic pain across musculoskeletal conditions. 2\. Use the CAP questionnaire alone or with substitute measures of activity in CNS pathways, demographic, and clinical variables to indicate pain levels at six and twelve weeks. 3\. Understand the relationship between CAP and simpler pain sensitivity assessment with laboratory pain sensitivity assessments as a tool to inform the current CNS activity contributing to pain. 4\. Evaluate associations between the CAP questionnaire and simpler pain sensitivity assessments with patient outcomes.
NCT06071715
When a limb is severed, pain perceived in the part of the body that no longer exists often develops and is called "phantom limb" pain. Unfortunately, phantom pain goes away in only 16% of afflicted individuals, and there is currently no reliable definitive treatment. The exact reason that phantom limb pain occurs is unclear, but when a nerve is cut-as happens with an amputation-changes occur in the brain and spinal cord that actually increase with worsening phantom pain. These abnormal changes may often be corrected by putting local anesthetic-called a "nerve block"-on the injured nerve, effectively keeping any "bad signals" from reaching the brain with a simultaneous resolution of the phantom limb pain. However, when the nerve block resolves after a few hours, the phantom pain returns. But, this demonstrates that the brain abnormalities-and phantom pain-that occur with an amputation are not necessarily fixed, and may be dependent upon the "bad" signals being sent from the injured nerve(s), suggesting that a very long peripheral nerve block-lasting many months rather than hours-may permanently reverse the abnormal changes in the brain, and provide definitive relief from phantom pain. A prolonged nerve block lasting a few months may be provided by freezing the nerve using a process called "cryoneurolysis". The ultimate objective of the proposed research study is to determine if cryoanalgesia is an effective treatment for intractable post-amputation phantom limb pain. The proposed pilot study will include subjects with an existing above-knee amputation who experience intractable daily phantom limb pain. A single ultrasound-guided treatment of cryoneurolysis (or sham block-determined randomly like a flip of a coin) will be applied to the major nerves of the thigh. Although not required, each subject may return 4-6 months later for the alternative treatment (if the first treatment is sham, then the second treatment would be cryoneurolysis) so that all participants have the option of receiving the active treatment. Subjects will be followed for a total of 12 months with data collected by telephone.

The TMW intervention aims to foster parental behaviors that facilitate children's language emergence at a critical developmental stage, and thus will be implemented at 13-16 months of age. The investigators hypothesize that the primary effects of the TMW Intervention will significantly 1) improve low-SES parents' understanding of the importance of parent language in a child's development, 2) increase parents' linguistic interaction, responsiveness, and overall engagement with their children, and 3) increase children's language output, as measured through LENA (child vocalization count, conversational turn count), coded video interaction (number of types, tokens and utterances for both children and adults), audio recordings from The Three T's application during the video sessions, and a battery of assessments targeting linguistic and cognitive development. Furthermore, the investigators hypothesize that increased parental interaction will result in 4) an improvement in children's socioemotional development as assessed by the Social Emotional Ages and Stages Questionnaire (ASQ-SE). Finally, the investigators hypothesize that these socioemotional and linguistic gains through early development, along with sustained increased parental engagement, will be expressed in 5) increased child school readiness upon kindergarten entry as assessed by Woodcock-Johnson Psycho-Educational Battery (WJ). Added 2023: an 8th child-assessment, parent/child interaction video session, and parent surveys have been added with the original sample to measure long-term outcomes of children whose parents participated in the home visiting intervention.
