There are about 3543 clinical studies being (or have been) conducted in South Africa. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The goal of this observational study is to investigate how adverse experiences during childhood are linked to people experiencing persistent pain and fatigue in adulthood. The questions the investigators aim to answer are: 1. Does participant-reported childhood adversity predict levels of IL-6 and TNF-α after in vitro provocation of whole blood using endotoxin? 2. Do levels of IL-6 and TNF-α after in vitro immune provocation using endotoxin predict vulnerability to persistent pain and fatigue after in vivo immune provocation (tetravalent influenza vaccine)? 3. Do levels of IL-6 and TNF-α after in vitro immune provocation using endotoxin predict vulnerability to persistent pain and fatigue after in vivo neural provocation? For this study, the investigators will recruit and enrol 96 healthy human adults (18 - 65 years old) with a range of adverse experiences during childhood. Participants will attend 2 study sessions during which the investigators will take a sample of blood, assess pressure pain threshold before and after cold water immersion, assess heart rate variability, and assess the surface area of secondary skin hypersensitivity after electrical stimulation. At the end of the first session, participants will receive the influenza vaccination.
The goal of this single-center, open-labelled, clinical trial in two groups aims to proof that a specific group of antibiotics (carbapenems) can be used to treat pulmonary tuberculosis if it is combined with another antibiotic (amoxicillin/clavulanate). A total of 113 male or female participants (8 groups and 9 treatment regimens as group 8 was split into 2 groups of 4 participants receiving Rifafour e-275), aged between 18 and 65 years (inclusive), with newly diagnosed, smear-positive, pulmonary TB.
This study will assess the pharmacokinetics, safety, tolerability, maintenance of virological suppression and patient reported outcomes for participants receiving CAB and RPV LA injections following SC administration in the anterior abdominal wall SC tissue compared with IM administration in the gluteus medius muscle in adult participants living with HIV-1 infection in the FLAIR study (NCT02938520).
The investigated product is a Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Booster Vaccine candidate optimized for the Omicron/BA.2 variant. There are currently no licensed, variant-optimized vaccines to prevent infection with SARS-CoV-2 Omicron/BA.2. Approved or authorized SARS-CoV-2 vaccines are expensive, require a stringent cold chain, and have large-scale manufacturing issues, resulting in very limited availability in low- and middle-income countries (LMICs). Given the rapid global spread of the Omicron/BA.2 variant and potential for future novel SARS-CoV-2 variants, the rapid development of an easy-to-manufacture and easy-to-distribute vaccine is of great importance. The objective of the study is to assess the tolerability, safety, and immunogenicity of different doses and routes of administration of the Alveavax-v1.2 vaccine in healthy individuals. The study aims to evaluate: - the safety and tolerability of Alveavax-v1.2 in healthy participants compared to a control booster vaccine in a dose-finding design; - the immunogenicity against SARS-CoV-2 BA.2/Omicron after a booster dose of Alveavax-v1.2; - the clinical efficacy against SARS-CoV-2 after a booster dose of Alveavax-v1.2; - and the success rate of intradermal (ID) injections.
More than 1.5 billion people around the world experience hearing loss, of whom at least 430 million experience disabling hearing loss that will require rehabilitation. The majority of people have mild to moderate hearing loss and can benefit from hearing aids. However, hearing aid adoption around the world has been low, with global hearing aid coverage being less than 11%. This is partly due to limited access to hearing healthcare services and the high cost of hearing devices. However, there have been significant efforts to improve access to hearing healthcare services. This includes rapid advances in hearing aids and new service-delivery models leading to more affordable and accessible options such as Over-the-Counter (OTC) hearing aids. On the 17th of October 2022, the Food and Drug Administration (FDA) established a regulatory category for OTC hearing aids. The final rule allows consumers with perceived mild to moderate hearing impairment to purchase hearing aids directly from stores or online retailers without the need for a medical exam, prescription or a fitting by an audiologist. The FDA defined two sub-categories for OTC hearing aids, namely 1) OTC hearing aids with standardized output profiles (i.e., pre-set programs) and 2) self-fitting OTC hearing aids which allow users to program their hearing aids with a self-fitting strategy and also customize their hearing aid settings according to their needs and preferences. Sabin et al. (2020) was the first study to validate a self-fitting method using the Bose prototype hearing aid. This self-fitting method allowed users to select their own signal processing parameters using a mobile application consisting of two wheels that simultaneously control the gain and compression of all frequency bands. Sabin et al. (2020) evaluated the real-world performance of this approach by comparing gain, sound quality and clinical measures of hearing aid benefit and satisfaction between a group using the self-fitting method and a group that was professionally fitted with the same hearing aid. The gain selected by the self-fit group was within 1.8 dB overall and 5.6 dB per band compared to the gain selected by the audiologist. Participants in the self-fit group reported better sound quality, and there were no differences in clinical measures of hearing aid benefit or satisfaction. Although a number of studies have compared self-fitting OTC devices to conventional hearing aids fitted by hearing healthcare professionals, no study has compared different self-fitting strategies in the same OTC device. Therefore, this study aims to compare the existing self-fitting strategy of the Lexie Powered by Bose hearing aids (i.e., direct adjustment) to a recently validated in-situ audiometry fitting strategy. The in-situ audiometry fitting strategy consists of in-situ thresholds measurements conducted at 500, 1000, 2000 and 4000 Hz through the hearing aids, which will be used with a proprietary fitting algorithm that is based on National Acoustics Laboratories' Non-Linear Version 2 (NAL-NL2) to self-program the hearing aids.
This study has two main objectives. First, the clinical characteristics and outcomes of hospitalized patients with symptomatic Covid-19 disease will be compared between persons with a history of past or current TB infection or disease and those, who have had no TB history. The possible impact of an HIV-coinfection will be also addressed in the planned investigations and analysis. Second, the long-term consequences and clinical outcomes of Covid-19 up to 12 months post-infection will be analysed in both groups (with and without TB history) with the main focus on cardio-pulmonary outcomes.

Randomised trial comparing the efficacy and feasibility of using a sterile closing pack to reduce postpartum sepsis
CS5_3 aims to evaluate the tolerance and to adjust the mode of administration of 4 different conditions of cryotherapy treatments applied on the brown spots of the face and hands with 3 prototypes. A brown spot is defined as solar or senile lentigo and post-inflammatory hyperpigmentation (PIH). Each treatment corresponds to a combination of a specific sequence of a cryogenic spray and of a frequency of application. The study will evaluate 3 prototypes : - Prototype 1 : SN from (816-v1 001) to (816-v1 100) - Prototype 2 : SN from (816-v1 101) to (816-v1 150) - Prototype 3 : SN from (816-v1 151) to (816-v1 200) Prototypes will be applied on the face and hands according to specific frequencies of application.
The aim of this study is to independently evaluate the usability and performance of rapid assays detecting SARS-CoV-2 antigen(s) and intended for self-testing. For this, the results of the test performed and interpreted by an untrained lay user will be compared to the results obtained by a trained healthcare professional using the same test kit, and, separately, to the current gold standard for testing, RT-PCR detecting SARS-CoV-2 RNA
