The purpose of this study is to assess the impact of a personal care product on vaginal health in individuals with a self-reported history of vaginal discomforts such as malodor, bothersome discharge, itching, irritation, and dryness. The personal care product, VH-01 contains a prebiotic and three distinct strains of Lactobacillus crispatus, a microbe commonly found in healthy vaginal microbiomes. The study will be a randomized, placebo-controlled trial where the test product will be compared to a placebo in a 2:1 manner. Participants will be asked to complete online questionnaires and provide vaginal samples to assess microbial communities. The aims of this study are to assess: 1. The user experience and acceptability of VH-01 vaginal suppository vs. placebo. 2. Attitudes and perceptions of VH-01 vaginal suppository usage vs. placebo. 3. Health-related quality of life during the use of VH-01 vaginal suppository vs. placebo. 4. Changes in self-perceived vaginal discomforts during the use of VH-01 vaginal suppository vs. placebo.
The purpose of this observational study is to verify the user acceptance of the Open Standard Respirator-Model 1 (OSR-M1) by clinicians through pre-trial survey and quantitative fit-testing and post-trial feedback surveys. This study will help to guide further design modifications and clarify quantities of employee populations that may benefit from elastomeric respirator use for the deployment of OSR M1 Air Purifying Respirators (APRs) in the Wake Health network.
The primary aims of the study are to assess the user experience and initial efficacy of a mobile application designed to reduce problematic alcohol use. The application utilizes drinking limits, defined by the user, to pace alcohol consumption during drinking occasions. The mobile application will be compared to strategies for tracking drinking detailed within the National Institute on Alcohol Abuse and Alcoholism Alcohol Moderation Strategies (https://www.rethinkingdrinking.niaaa.nih.gov/thinking-about-a-change/strategies-for-cutting-down/tips-to-try.aspx). Primary outcome variables, in addition to variables assessing user design experience of the application and use of moderation strategies, include (1) negative consequences of alcohol use during a 14 day observation period, and (2) number of drinks consumed per drinking day during a 14 day observation period.
The objective of this study is to confirm procedural performance of the Exalt Model D Single-Use Duodenoscope in Endoscopic Retrograde Cholangio-Pancreatography (ERCP) and other duodenoscope-based procedures.
Recently, Maziak established a clinical lab at FIU to test the potential of waterpipe tobacco flavor regulation by the FDA. Given the importance of flavors on adolescent ENDS uptake and use, this lab is equipped to study the impact of flavor manipulations among adolescent ENDS users. In this study will recruit 80 young (18-24) JUUL users, in a 2x2 cross over lab study where in one condition they will use their JUUL preferred flavor and the other JUUL standard tobacco flavor. Our aims are to; Aim 1: Compare satisfaction, withdrawal suppression, and harm perception between tobacco-flavored and preferred flavor JUUL. This analysis will reveal the extent to which preferred flavor contributes to smoking satisfaction, withdrawal and craving suppression, and harm perception, compared to the standard tobacco flavor. Aim 2: Compare puff topography and plasma nicotine levels between tobacco-flavored and preferred flavor JUUL. This analysis will examine the extent to which preferred flavor contributes to puffing behavior and toxicant exposure compared to the standard tobacco flavor. Aim 3: Compare exhaled breath condensate (EBC) between tobacco-flavored and preferred flavor JUUL. This analysis will be the first to examine exposure to toxic aldehydes (formaldehyde, acetaldehyde, acrolein, benzaldehyde, and propionaldehyde) produced when using preferred flavor compared to the standard tobacco flavor. Utilizing powerful clinical lab methods, this study will provide a broad testing of the effect of flavor manipulation on college-aged JUUL users, and provide experimental evidence about the potential of flavor-limitation policies on young ENDS users in the US.
Presented as an online survey, this study seeks to better understand how Thorne customers are using and experiencing the new Hemp Oil + product and how they feel it compares in the marketplace. Hemp Oil + is a combination product with a proprietary blend of hemp, clove, black pepper, hops, and rosemary extracts. People who have independently elected to purchase and use Hemp Oil + before the study starts will be invited to voluntarily participate. If they meet study requirements and give consent they will answer questions online about their experience with Hemp Oil +. Questions address general demographics and wellness, general impressions of the product, how it compares to other products, and any effect it has had on their gastrointestinal health, physical discomfort, sleep, and mood. The survey is expected to take 15-30 min of participant time. Data will be analyzed to determine whether the customer experience with Hemp Oil + is as favorable as it seems from anecdotal reports. Analysis will also be conducted to find patterns that can inform future studies, marketing, and customer education efforts.

The goal of this prospective, international multi-centre pilot study is to assess the functionality and user experience of a new vital sign monitoring system in 20 patients and 20 nurses in the general ward at each centre. The patients will be monitored with a wireless, continuous vital sign monitoring systems and answer a questionnaire afterwards. They will in addition have vital signs monitored as per standard practice. The nurses will answer a questionnaire after having had the responsibility for a monitored patient for a full shift. The main aims are: To determine the frequency of alerts activated in the app in relation to the alerts that should be activated based on measured data, to explore current practices of in-hospital monitoring by semi-structured interviews to map differences across systems and to test nurse and patient satisfaction.
The goal is to understand the critical factors associated with outcome acceptance following upper limb loss. The investigators aim to develop a unified theoretical model that describes the psychosocial experience of upper limb prosthesis use and predicts outcome acceptance following upper limb loss. The investigators will also examine experiences with prosthesis education, selection, and training as well as how psychological and social issues impact prosthesis use. In addition, the investigators will use the findings to develop a prototype decision tool to assist with matching persons to prostheses. Study findings will help providers, technology developers, and researchers better understand the complex experience of upper limb prosthesis use. This conceptual framework will enable clinicians and researchers to evaluate and predict patient outcomes following limb loss, and to design interventions that improve outcomes. The proposed study is a mixed methods (qualitative and quantitative) study using an observational design. The qualitative component of the study will involve data collection through telephone interviews with 42 participants and analyses using a grounded theory approach with constant comparison methods. The quantitative component involves administration of standardized measures quantifying constructs of the theoretical model in 120 participants and analyses to produce a structural equation model of outcome acceptance. Participants will include persons with unilateral acquired upper limb loss at the trans radial or trans humeral level who use currently available prosthetic devices. Up to 16 individuals will participate in a series of focus groups that will be conducted to provide feedback on the model generated from previous data.
The purpose of this study is to (a) adapt existing user sensory perception and experience (USPE) items/instruments generated for rectal gel/cream formulations to include USPEs specific to suppository forms for rectal and vaginal use; (b) for both male and female cohorts: to capture the experience of suppository use in the context of receptive anal intercourse (RAI); and (c) for female cohort only: to capture the experience of suppository use in the context of vaginal-penile intercourse (VI), and to compare USPEs of suppository use in the context of RAI to USPEs of suppository use in the context of vaginal-penile intercourse.
The purpose of this study is to: (a) adapt existing vaginal USPE items/instruments for evaluation of similar elements of rectal compartment use; (b) develop these scales using 3 distinct semi-solid formulations that represent a range of physicochemical and rheological properties of microbicides that are currently being designed for dual compartment use; and (c) develop novel USPE instruments to capture the experience of product use in the context of receptive anal intercourse (RAI) in both male and female cohorts.
The purpose of this study is to answer the following questions: (a) how do sexual and reproductive health (SRH) delivery method characteristics play a role in user preference for specific SRH methods; (b) can we understand the interplay between salient SRH product characteristics and effective use; (c) does effective use differ by indication (e.g., whether the product is for contraception or lubrication); and (d) can this knowledge help product developers better understand how to design new SRH products and develop behavioral (or point-of-care) interventions to optimize use?
Hearing loss is among the top service-connected disabilities in Veterans. Hearing aids are the primary intervention for hearing loss. Half of the hearing aids dispensed in the VA are to Veterans who are receiving replacement amplification. Many Veterans would like their replacement hearing aids mailed to them, but they are required to travel to the clinic so that the fit of the hearing aid can be verified. There are standard fitting procedures, such as those used in infants and children, that use a coupler to simulate the patient's real ear to verify the hearing aid fitting. The results of this study should determine the efficacy of a coupler-based hearing-aid fitting protocol that would not require the Veteran to attend the fitting appointment, thereby contributing to improved Veteran-Centric care.
The overall aim of the study is to compare the verification accuracy and hearing-aid outcomes between the traditional, fitting approach where the patient is present during the visit and a coupler-based fitting approach where the patient is not present and mailed their hearing aids. If the coupler-based fitting protocol tested in this study as effective as the traditional fitting protocol, then patients receiving replacement hearing aids may circumvent a face-to-face visit.
This is a multi-site, prospective, open-label, randomized, 2 period cross over study comparing the subjects' current 32G pen needle (four groups of pen needles) to the BD Nucleus pen needle. The study will consist of two 15 day periods ( in which the subject will use each pen needle \[BD Nucleus pen needle or subject's current pen needle, order randomized\] for injection. At the end of the last study period, each subject will be asked to evaluate his or her perceptions using a 150mm relative VAS scale.
To pilot test the appeal of non-tobacco oral nicotine products in cigarette smokers, smokeless tobacco users, and oral nicotine users.
This Basic Experimental Studies Involving Humans (BESH) study investigates phosphene perception and performance factors in blind participants implanted with the Argus II retinal prosthesis system. Using paired-electrode stimulation, we analyze how phosphene shape and number are influenced by neuroanatomical factors, stimulus parameters, and spatial offsets. Additionally, we examine the causes of high current thresholds and limited spatial resolution, which impede pattern vision in Argus II devices. This research aims to provide insights for optimizing stimulation strategies and improving retinal prosthesis design.
The main aim is to evaluate the relative abuse potential of soticlestat in healthy adults who has used central nervous system (CNS) depressants for recreational nontherapeutic reasons.
This is a prospective cohort study of older patients receiving implantable cardioverter-defibrillators. The purpose of the TRACER-ICD study is to conduct a prospective cohort investigation with the goal of 500 patients age \>65 receiving new primary prevention implantable cardioverter-defibrillators (ICDs). Patients will be followed quarterly for 18 months with interviews, electronic record review, and remote monitoring to characterize clinical and functional trajectories following device implantation, with permission for extended electronic follow-up for up to 10 years (Aim 1). This cohort will support validation and refinement of an established model for predicting personalized outcome profiles for ICD therapies and death (Aim 2). Lastly, we will combine electronic record review with semi-structured interviews with patients and physicians to evaluate physician and patient experiences with a prototype individualized shared decision-making (SDM) tool (Aim 3).
This study aims to use validated tools as well as new technology to examine changes in bleeding patterns among women who are initiating the copper T380A IUD.
Injection drug users (IDUs) constitute 60% of the approximately 5 million people in the U.S. infected with hepatitis C virus (HCV). HCV treatment leading to sustained viral response (SVR) is associated with increased survival. However, IDUs have had poor access to HCV care and their success in HCV treatment has been limited. With direct-acting antiviral agents, HCV treatment delivered within large clinical trials leads to SVR or cure in over 70% of genotype-1 infected patients, compared to 45% with previous therapies. However, SVR rates are as low as 14% in real-world settings. The majority of patients who fail to achieve SVR will develop drug resistance, but the optimal adherence level to minimize resistance is unknown. If HCV treatment continues to be delivered within current models of care, most IDUs will not only fail treatment and develop resistance, but may transmit resistant viruses to others. We have previously developed a multidisciplinary model of HCV care which integrates on-site primary care, substance abuse treatment, psychiatric care, and HCV-related care within opiate agonist treatment clinics. To maximize treatment outcomes, we piloted two models of intensive HCV-related care: directly observed therapy (DOT), and concurrent group therapy (CGT). In our DOT model, pegylated interferon is administered once weekly, if applicable, and one daily dose of oral medication is administered at the methadone window. In our CGT model, patients initiate HCV treatment within a once weekly treatment group which provides powerful social support to mitigate fears of side effects, promote efficient education, and deliver weekly injections, if applicable. It is unknown whether either model is better or more cost-effective than standard on-site care. PREVAIL 1: In the proposed study, 150 IDUs with chronic HCV (genotype 1) will be recruited from methadone clinics and randomized to one of three models of care: DOT; concurrent group treatment; or standard on-site care. Our specific aims are: 1) To determine whether either of two intensive on-site HCV treatment models (DOT or concurrent group treatment) is more efficacious than standard on-site treatment for enhancing adherence and SVR, and decreasing drug resistance; (2) To determine the incidence and factors associated with the development of drug resistance in IDUs; (3) To perform cost and cost-effectiveness analyses of each model; (4) To examine the impact of HIV coinfection on adherence and virologic outcomes among HCV-infected IDUs. PREVAIL 2: In the proposed study, 60 IDUs with chronic HCV (genotypes 1 2, 3 and 4) will be recruited from opiate agonist treatment programs and started on HCV treatment. Subjects will be offered the choice of model of care (either standard on-site, DOT, or concurrent group treatment). Our specific aims are: (1) to determine rates of adherence and SVR in a cohort of opiate agonist treatment patients initiating treatment with sofosbuvir-based regimens and (2) to determine adherence rates over time in drug users (genotype 3 and genotype 1 / IFN-ineligible) initiating a 24 week IFN-free regimen. PREVAIL 3: In the proposed study, 60 IDUs with chronic HCV (genotype 1 and 4) will be recruited from opiate agonist treatment programs and started on HCV treatment. Subjects will be offered the choice of model of care (either standard on-site, DOT, or concurrent group treatment). Our specific aims are: (1) to determine rates of adherence and SVR in a cohort of opiate agonist treatment patients initiating treatment with oral DAA combination of sofosbuvir and simeprevir or fixed dose of sofosbuvir and ledipasvir and (2) to determine adherence rates over time in drug users.
Deployment of Secure Messaging (SM) in primary care and women's clinics throughout the Veteran Health System by 2011 was an implementation priority for the Secretary and Under Secretary for Health for FY11 under the VHA T21 initiative. Secure Messaging is in early phases of implementation, this eHealth tool requires thoughtful evaluation to promote the successful implementation and dissemination of this tool. The primary aim of this project is to describe Veterans' experiences when using the SM feature on MyHealtheVet (MHV). This project has local, VISN, and national impact on the implementation and sustainability of the SM feature on MHV through its qualitative and quantitative examination of users' experiences. Findings from this research explores why Veterans choose to, or not to, use the SM feature on MHV, identify facilitators and barriers, and examine if experiences differ by health literacy or computer literacy. In addition to the interview data, findings from the usability testing and the quantitative survey findings build knowledge about Veterans' experiences using the SM feature on MyHealtheVet. These data will inform systems improvements, educational approaches, and marketing strategies to increase adoption and long-term utilization among Veterans.
Cannabis is the most used illicit substance in the United States. Previous studies suggest that atypical antipsychotics decrease the frequency and the amount of substance use in subjects with and without psychotic illness. So far, there are no controlled studies assessing the effectiveness of atypical antipsychotics for decreasing cannabis and other substance use in individuals with cannabis use disorders. The investigators postulate that the atypical antipsychotic quetiapine ER is an effective agent for improving substance use outcomes in subjects with cannabis use disorders. In this pilot study, the investigators will test this hypothesis in heavy cannabis users (i.e., individuals who are cannabis dependent and smoke three times or more per week). Because 50% of these heavy cannabis users report histories of psychotic experiences (i.e., attenuated positive symptoms) while smoking and are at risk for recurring psychotic symptoms, the investigators will focus this pilot clinical trial on this subgroup of cannabis users in order to increase the risk/benefit ratio of this study and target a population that may also benefit from the antipsychotic effect of quetiapine ER. Considering the lack of controlled studies assessing the efficacy of atypical antipsychotics in heavy cannabis users, assessing the effectiveness of an atypical antipsychotic medication on substance use and clinical outcomes in this population is critical for improving the prognosis of these individuals. Thus, the aims of this randomized, double-blind, placebo-controlled study are to assess the efficacy of an atypical antipsychotic (quetiapine ER) in 120 subjects with cannabis dependence, a recent history (within a year) of attenuated psychotic symptoms, and using cannabis 3 times or more per week for: (1) decreasing the use of cannabis and other substances; and (2) preventing the recurrence of psychotic experiences. The investigators will also assess the effects of quetiapine ER on craving and mood, and its tolerability. This project will be a 12-week, randomized, double-blind, placebo-controlled study with quetiapine ER and it will include a comprehensive assessment of symptoms, substance use, and side effects. This study will benefit the field by providing unique data on the relative efficacy and tolerability of treatment with atypical antipsychotics in heavy cannabis users with a vulnerability to psychosis. This study will be the basis for future studies assessing the long-term efficacy and tolerability of atypical antipsychotics in individuals with cannabis use disorders.
