NCT ID: NCT05055440 Recruiting - Clinical trials for COVID-19 Respiratory Infection

Evaluation of Peripheral Muscle With Ultrassonografic of Critical Patients With Covid-19

Start date: August 10, 2020
Study type: Observational

Currently, the tools available for assessing peripheral muscle dysfunction in the intensive care setting require patient collaboration. Several studies have shown that peripheral muscle ultrasound is capable of reliably detecting morphological changes in critically ill patients, in addition to contributing to the identification of patients at higher risk of prolonged complications, especially when performed daily. In this sense, a valid, non-volitional alternative capable of determining muscle mass is through ultrasound assessment. However, current studies are characterized by a lack of standardization in their protocols, which include proper positioning of limbs, transducer, clear reference points and techniques for better visualization of the assessed muscle, in addition to significant methodological defects and inadequate sample sizes. We believe that, together with a tool capable of determining muscle mass and being a safe and non-invasive method, we can contribute to a more complete assessment of these patients, exploring outcomes such as survival, length of stay in the ICU, extubation success and functional capacity. In addition to having the potential to serve as a biomarker of muscle strength during rehabilitation, given little knowledge about the long-term physical consequences of COVID-19, thus promoting a more complete assessment, exploring morphological characteristics of the peripheral muscles resulting from the hospitalization process. and assisting the physiotherapist in clinical decision making in rehabilitation.

NCT ID: NCT05052398 Recruiting - Clinical trials for Chemotherapy-induced Peripheral Neuropathy

Proof of Principle Study Evaluating Gonyautoxins NEURO SERUM, on Chemotherapy-induced Peripheral Neuropathy

Start date: January 14, 2021
Phase: Phase 1/Phase 2
Study type: Interventional

Proof-of-concept study to assess the effects of gonyautoxins (PSP NEURO SERUM) on safety and tactile sensitivity on patients with chemotherapy-induced peripheral neuropathy (CIPN). This is a multicenter, prospective proof-of-concept study in patients with solid tumors affected by CIPN. The study will be divided into two parts: Part 1 will assess the activity and tolerability of PSP NEURO SERUM and part 2 consists of a randomized cohort that will compare the activity of PSP NEURO SERUM vs placebo. Part 2 will depend on the results of part 1. If there are less than 8 responses in part 1, the study will be interrupted, and it will not be recommended to proceed with part 2. The detailed description of the study will be given only for part 1.

NCT ID: NCT05047562 Recruiting - Low Back Pain Clinical Trials

Effect of Pilates and Segmental Stabilization in Elderly People With Low Back Pain

Start date: June 13, 2019
Phase: N/A
Study type: Interventional

INTRODUCTION: Low back pain is an important health condition with great consequences from the socioeconomic point of view and is associated with high costs for the health system, absenteeism at work and reduced functional performance. It is considered one of the most relevant health problems in the elderly, with point prevalence estimates higher than for other musculoskeletal conditions. It can be defined as any pain between the last ribs and the lower gluteal folds, with or without pain in the lower limbs, manifesting itself acutely, subacutely or chronically. OBJECTIVE: To compare the effect of the Pilates method versus segmental stabilization in elderly people with chronic low back pain. METHOD: 60 elderly people with chronic low back pain will participate in the study and will be randomized into two groups: Pilates Group (GP) and Segmental Stabilization Group (SG). The two treatments will have 16 individual sessions, twice a week. Pain will be assessed using the visual analogue pain scale; functional disability, using the Oswestry disability index; excessive fear of movement and physical activity, by the Tampa scale of kinesiophobia; level of confidence in the balance for specific activities, by the ABC scale and; activation of the transversus abdominis muscle by pressure biofeedback. Individuals will be evaluated in four moments: before the first session, after the last session, three and six months after the end of the treatment to verify the effects in the medium term. Patient allocation and assessments will be performed by a blind examiner. Data will be analyzed using the ANOVA procedure and Tukey's Multiple Comparison test. The significance level will be 5%. A hipótese deste estudo é que o grupo que realiza exercícios de Pilates obtém ganhos mais obtem que o grupo que realiza exercícios de estabilização segmentar em todas as variáveis ao final do tratamento.

NCT ID: NCT05046145 Recruiting - Inflammation Clinical Trials

Effects of Non-invasive Neuromodulation on Food Desire, Chewing Pattern, Executive Functions and Oxidative Stress.

Start date: July 13, 2021
Phase: N/A
Study type: Interventional

From the change in self-regulation, memory is inhibited, allowing individuals to suppress or ignore unwanted or outdated associations and thus help to filter information relevant to dietary goals from irrelevant information. Provoking changes in neuroplasticity and cortical excitability contribute to the regulation of neural activity. Both could be modified by applying direct electrical current to the sensorimotor cortex, with polarity/current-dependent results, and their effect would last for hours after the end of stimulation. Transcranial Direct Current Stimulation (tDCS), translated into Portuguese as Estimulação Transcraniana por Corrente Contínua (ETCC) is a neuromodulating tool in which a low-intensity electrical current is applied to the scalp to modulate neuronal activity.

NCT ID: NCT05044637 Recruiting - Malaria, Vivax Clinical Trials

Study to Evaluate Primaquine for Radical Cure of Uncomplicated Plasmodium Vivax Malaria in Children

Start date: August 26, 2021
Phase: Phase 2
Study type: Interventional

The main determinant of primaquine efficacy is the total dose of primaquine administered, rather than the dosing schedule. Infants and children younger than 4 years of age are at a higher risk of frequent relapses than older age groups, which may lead to severe anaemia. In view of this issue, after Glucose-6-phosphate dehydrogenase (G6PD) testing, WHO recommends the use of a low dose (0·25 mg/kg of bodyweight) of primaquine for 14 days in infants aged 6 months and older, as a follow-up treatment for malaria caused by P. vivax and P. ovale. Nevertheless, previous trials have demonstrated that the standard low dose regimen of primaquine (3.5 mg/kg total) fails to prevent relapses in many different endemic locations. For this reason, the 2010 WHO antimalarial guidelines now recommend a high dose regimen of 7 mg/kg (equivalent to an adult dose of 30mg per day), although many countries still recommend lower doses for fear of causing more serious harm to unscreened G6PD deficiency patients. The pharmacokinetics of several antimalarial drugs are different in children younger than 10 years of age or who are underweight for their age compared with children of 10 years and older and adults.The doses of several antimalarials in children are suboptimal. This oversight is a consequence of designing dosing regimens in a different population (i.e., adults) for the one most affected by the disease and this has led to revisions of some dosing recommendations. The different pharmacokinetic performance of drugs in children might also relate to maturation (e.g., of metabolic processes, particularly in the first 2 years of life). Pharmacogenomic factors affecting drug metabolism are increasingly being studied. Polymorphisms in cytochrome P4502D6 are associated with different primaquine metabolizer phenotypes with resulting differing efficacies for radical cure. Shorter courses of higher daily doses of primaquine have the potential to improve adherence and, thus, effectiveness without compromising efficacy. If the efficacy, tolerability and safety of short-course, high-dose primaquine regimens can be assured across the range of endemic settings, along with reliable point-of-care G6PD deficiency diagnostics, then this would be a major advance in malaria treatment by improving adherence and thus the effectiveness of anti-relapse therapy.
