84 Clinical Trials for Various Conditions
The purpose of this study is to examine the inter/intra rater reliability as well as the validity of the Swing Test in asymptomatic adults . In addition, this study will examine if there are musculoskeletal predictors to the movement quality of the swing test. The Swing Test is a movement test used by physical therapists to identify movement problems during a simulated running stride
Managing complicated urinary tract infections (cUTIs) poses significant challenges, often resulting in the over-prescription of empiric antibiotics. This approach exposes patients to multiple antimicrobials and raises the risk of inadequate treatment efficacy. The purpose of this study is to assess and compare the clinical utility of molecular testing (PCR) versus conventional culture and sensitivity (C\&S) in managing cUTI, to identify optimal management strategies for cUTI patients. This was a multi-center (6 sites in the united states), randomized, parallel, investigator-blinded, clinical trial to assess the clinical utility of PCR by comparing the diagnostic and therapeutic outcomes of PCR diagnostic methods to those of conventional C\&S in managing cUTIs in adults. All patients who met all the inclusion criteria and non of the exclusion criteria and signed an informed consent form were enrolled and randomized to one of two testing protocols used to guide treatment (PCR guided Arm, and C\&S guided Arm). Patients were randomized in a 1:1 ratio based on their unique sequential randomization numbers assigned at enrollment. Urine samples were collected from all patients and tested using both PCR and C\&S methods before randomization; however, investigators remained blinded to the comparator test results throughout the trial. To ensure unbiased treatment decisions, clinicians were blinded to the comparator test results. Treatment was prescribed solely based on the assigned test-PCR results for the PCR arm and C\&S results for the C\&S arm. The comparator test results remained blinded until the end of the study (EOS) Urine specimens were collected using a clean-catch midstream technique at two distinct time points-at baseline visit/before randomization (Day1) and at EOS visit (Day 28)-following targeted therapy based on the assigned diagnostic arm. Collected samples were immediately stored at 2-8 ◦C until analysis to preserve sample integrity. Upon receipt, urine samples were aliquoted for parallel testing, with one portion analyzed using PCR (QuantStudio 7 or 12 and KingFisher) and the other processed using C\&S methodologies. Molecular testing (Doc Lab UTM 2.0) involved qualitative PCR amplification targeting 28 uropathogen species and 16 classes of antibiotic resistance genes, covering both bacterial and fungal pathogens. All urine samples for urine C\&S were shipped to the central laboratory. The urine culture, isolation of uropathogen(s), initial identification of pathogen(s), and bacterial counts in urine were conducted in the central laboratory. The urine samples were cultured and quantified using a calibrated loop to identify a quantitative count of bacteria at a lower limit of 10\^5 CFU/mL. All purified pathogen(s) were further analyzed for species identification and antimicrobial sensitivity The primary endpoint was the number (and percentage) of subjects in each study arm with favorable clinical outcomes (FCl) at the EOS visit. The FCl was defined as a patient's clinical response, assessed by the treating investigator, indicating either clinical improvement or cure. Clinical improvement was defined as the resolution of at least one symptom of cUTI present at baseline, absence of new cUTI symptoms, and/or avoidance of parenteral antibiotic therapy following randomization. Clinical cure was defined as the complete resolution of all acute signs and symptoms of cUTI present at baseline, to the extent that no further antimicrobial therapy (either IV or oral) was required for the treatment of the cUTI. The secondary endpoint included several assessments: * Number (and percentage) of subjects with microbiological eradication at the EOS, defined as achieving a quantitative urine culture at the EOS indicating a reduction of all uro-pathogens present at baseline to \<10\^5 colony forming unit per milliliter (CFU/mL) and the absence of baseline pathogens detected by EOS urine PCR (Cq \> 33); * Subjective measurement of treating investigator satisfaction score through a questionnaire at EOS, evaluated factors such as the ease of interpreting the test result, its availability, and its usefulness in clinical decision-making and patient management compared to the comparator; * Comparison of turnaround time between molecular diagnostic procedures and conventional diagnostic * Overall agreeability between the diagnostic results generated by PCR versus C\&S as assessed by discordant analysis * Assessment of the favorable clinical outcome of patients with discordant results \[PCR(+), CS(-) and PCR(-), CS(+)\]
To date, there is no valid and reliable measure of continuous inter-limb stability available to healthcare teams treating people with lower limb loss. Determining these characteristics of this parameter for this population is important because superior stability has been linked to increased physical activity and strength in similar populations, making it a potential vital contributor to mobility improvement of Veterans with limb loss. It is also crucial that healthcare providers can easily measure continuous stability in the clinic instead of relying on expensive laboratory equipment. The overall goals of this study are to determine the reliability and validity of continuous inter-limb stability of Veterans with lower limb loss and determine if this parameter can be captured using accessible wearable technology. Consequently, clinicians can improve continuous stability through proper rehabilitation to positively impact the functional mobility and overall quality of life of Veterans with lower limb loss.
The goal of this observational study is to assess the reliability and validity of the 9-object MLSDT for evaluation of participants with moderate to severe vision impairment when tested without a wearable low-vision magnifying aid (eGlasses) and then with eGlasses. These results will be compared to ETDRS testing results for the same participants without eGlasses and then with eGlasses. Two cohorts will consist of participants who have vision loss due to STGD or geographic atrophy (GA) due to age-related macular degenerations (AMD). Normally sighted participants will provide a control group.
The purpose of this study is to confirm the safety and efficacy of the ThinkSono Guidance System, a software data collection and communication tool designed to collect ultrasound data to help detect blood clots in veins. The ThinkSono system is CE Mark approved in the European Union and in clinical use in Europe. Usually, when an ultrasound is conducted to diagnose blood clots in veins, a sonographer (trained technologist who conducts ultrasounds) and/or radiologist will conduct the procedure, including a compression ultrasound exam, and the scan may require a bulky cart and ultrasound equipment. The ThinkSono Guidance System is a mobile software application that enables other healthcare professionals such as nurses, non-radiologist physicians including general practitioners, and other allied healthcare professionals to perform the ultrasound at the point of care using guidance from the software app. This is a multi-site non-randomized, double-blinded, prospective cohort pivotal study.
The purpose of this research study is to enhance inclusion and diversity in clinical trial enrollment by training participants to perform and provide feedback through a community-based protocol review process, called DIVERSE.

COVID-19 is an acute respiratory disease caused by Severe Acute Respiratory Syndrome coronavirus (SARS-CoV). Synairgen is currently conducting a global Phase III clinical trial of SNG001 to determine efficacy and safety in patients hospitalised due to COVID-19 that receive oxygen therapy. The primary endpoint in the Phase III trial (SG018) is to evaluate recovery in patients hospitalised due to COVID-19 that require oxygen therapy after administration of SNG001 compared to placebo. The primary endpoint will be determined using the World Health Organization Ordinal Scale of Clinical Improvement (OSCI) score, which will be assessed daily. The OSCI will be used in two different ways during SG018. When the patients are in hospital, the clinical study staff will assess the patient via observation using the OSCI. However, when patients have been discharged from hospital, the clinical study staff will assess the OSCI by asking two questions, one regarding the presence of COVID-19 symptoms and the other regarding usual activities returning to baseline levels. The patient will be required to answer both questions with either a 'yes' or 'no' answer. Daily assessments of the OSCI will be conducted via video call or telephone call after discharge from hospital. The two questions asked of patients when OSCI is assessed after discharge from hospital have been added to trial SG018 to allow assessment of OSCI to continue throughout the trial. As these are new questions and the data from these is being used to assess the primary endpoint in trial SG018, their relevance, ease of understanding and clarity needs to be shown, which is why this interview study is being conducted. Having patients comment on these questions will ensure that the way the benefit of treatment is being measured in SG018 is done in a robust and patient-centred way. The main aims of this qualitative pilot study are to: 1. To confirm how relevant, clear and easy to understand the two additional OSCI questions asked about COVID-19 symptoms and levels of usual activity are when patients have been discharged from hospital. 2. To find out what other symptoms and experiences patients hospitalised for COVID-19 might have had to see if these are reflected in the questionnaires used in SG018.
This study has 3 objectives: (1) demonstrate the effectiveness of balance training for people with COPD, (2) determine which patients with COPD respond best to balance training, and (3) calculate clinically meaningful changes in balance for patients with COPD.
This study will evaluate the validity of using a survey to quantify patient preferences at the point-of-care and the potential effectiveness of the survey to improve goal-concordant care. The primary hypothesis is that by identifying the strength of patient preferences for outcomes with this survey clinicians will be able to improve goal-concordant care by aligning clinical recommendations with patients' preferences. This study will have 50 patients with newly diagnosed hematologic malignancy complete the survey throughout their disease course (up to 2 years) and conduct qualitative interviews with a subset (n = 20) of participants. The information obtained from these participants will be used to refine the survey. Interviews with oncologists and palliative care specialists (up to 10) will inform implementation.

Prompted by the current COVID-19 pandemic, the American Academy of Ophthalmology has recommended the use of telemedicine to continue ophthalmic care while maintaining patient and provider social distancing. As part of remote examinations, patients may be expected to perform home eye testing for visual acuity and the use of various home visual acuity charts have been proposed to provide clinicians with this vital data. However, the use of home visual acuity exams has not been validated in our patient population. This project aims to determine the efficacy and validity of measuring visual acuity at home with a printed-out ETDRS chart.
The purpose of this study is to test two differently worded versions of the Shared Decision Making Process scale in a sample of adults who have recently made a decision about treatment of depression. The main goals are to gather evidence of reliability, to test whether the generic version has similar psychometric performance to the original, and to extend generalizability of the findings to younger adults.
The purpose of this study is to survey a sample of adults who have recently made a decision about treatment of high cholesterol or high blood pressure or a decision about screening for colorectal cancer, breast cancer, or prostate cancer. The main goal is to gather evidence of the validity and reliability of the Shared Decision Making Process scale. Secondary goal is to gather evidence on the quality of decisions for these common medical situations.
This study will recruit subjects online and randomly assigned them to one of four arms. The arms vary by clinical decision (colorectal cancer screening or treatment of high cholesterol) by video order (poor shared decision making followed by good or good shared decision making followed by poor). Participants will view two videos and complete the Shared Decision Making process survey along with a few other measures after each video. Our main hypothesis is that respondents watching the good shared decision making videos will score higher on the Shared Decision Making Process survey compared to those watching the poor videos.
The central goal of this proposal is to examine validity and sensitivity of RS-assessed skin carotenoid status as a marker of F\&V intake in a racially and ethnically diverse sample of individuals. First, investigators will examine the association (RS Device Validity) between RS-assessed skin carotenoids and the primary outcomes of objectively-measured plasma carotenoids and self-reported F\&V consumption across four diverse groups: African-American/Black, Asian, White, and Hispanic/Latino (n=213). Then the investigators will conduct a randomized controlled trial to define the relative skin carotenoid responses (RS Device Sensitivity) across racial-ethnic groups, in comparison with plasma carotenoid responses. The investigators will conduct a 6-week randomized controlled trial of a carotenoid-containing juice intervention \[placebo control, low and high dose juice (N=156). Finally, the genetic basis for racial/ethnic group differences in skin carotenoid responses to diet will be investigated through hypothesis-driven genomic analysis of participants from Aims 1 and 2.
The purpose of this study is to determine the validity of the Human Activity Profile and Godin self-report questionnaires of physical activity in persons seeking metabolic surgery.
The investigators propose a new imaging method for children born with congenital anomalies of the urinary tract that is a rapid, injection-, sedation-, and radiation-free alternative: the quick renal MRI. This proposal hypothesizes that the quick renal MRI has high validity compared to current radiologic standard for renal infection and scarring, the 99mTechnetium-dimercaptosuccinic acid (99mTc- DMSA) renal scan in the detection of acute renal infections and scars. If the quick renal MRI is accurate, it could potentially replace the DMSA scan for those specific questions and ease the burden of testing for children with chronic renal disease. Findings from these studies will provide preliminary data and rationale for a multi-centered study to further test this new technology. Participants will be 0-21 years of age and can expect to be on study for from 1 week (if enrolled in Aim 1) to 6 months (if enrolled in Aim 2).
