NCT ID: NCT05532748 Not yet recruiting - Clinical trials for Pulmonary Ventilation

Distribution of Pulmonary Ventilation With the Modified Pachon Incentive vs. Branded Respiratory Incentive

Start date: September 2022
Phase: N/A
Study type: Interventional

Incentive spirometry is a method to stimulate deep breathing and maximum sustained inflations, which provides participants with visual feedback on the inspiratory volume achieved, favoring lung inflation. Its multiple benefits and ease of use favor adherence, making it a common device used in the clinical environment. This device is used in pathologies or procedures that can cause decreased function and respiratory mechanics, such as thoracoabdominal surgeries, and is indicated to reduce the incidence of postoperative pulmonary complications. It is also indicated in the presence of pulmonary atelectasis or conditions that predispose to the development of pulmonary atelectasis, in patients with prolonged bed rest, patients with neuromuscular disease, patients with spinal cord injury, and patients undergoing coronary bypass, among others. In 2004, students from the Universidad del Valle carried out an investigation whose result was the creation of the Incentivo Modificado de Pachon, a handcrafted design device that allows mobilizing flows ranging from 600 CC/sec to more than 1400 CC/sec, which characterizes it as a flow respiratory incentive. In 2020, the device obtained the endorsement of the Superintendence of Industry and Commerce, however, to date no studies have been carried out that objectively verify the effect that the modified Pachon's incentive (Incentivo Modificado de Pachon by the name in Spanish) has on the distribution of ventilation in comparison with another Branded respiratory incentive. Electrical Impedance Tomography is a diagnostic tool that, employing a belt of electrodes connected around the user's chest, uses the electrical characteristics of the tissue, to provide information in a non-invasive, continuous way, on foot. bedside and radiation-free on pulmonary ventilation and perfusion, as it allows repeated imaging of tidal volume distribution, as well as distinguishing the characteristic regional filling and emptying of each lung, all in real-time and safely. In this study, the distribution of pulmonary ventilation between the modified Pachon's incentive vs. another Branded respiratory incentive will be compared, through electrical impedance tomography, in a healthy population of the city of Cali. The hypothesis to be tested is that the distribution of Pulmonary ventilation measured by Electrical Impedance Tomography is similar between the modified Pachon's incentive and another Branded flow respiratory incentive.

EEMAOHOP
Start date: October 12, 2022
Phase: N/A
Study type: Interventional

The aim of this article was to compare the efficacy of a messaging application compared to verbal instructions for improving oral hygiene in patients undergoing fixed orthodontic treatment with conventional ligature brackets (MBT technique) over a 3-month period. Randomized clinical trial of two parallel groups with 1:1 allocation ratio. Conducted in the orthodontic postgraduate clinic of the conventional ligation technique (MBT) at the Fundación Universitaria CIEO- UniCIEO, Bogotá, Colombia. Sixty patients aged 18 to 30 years with periodontal health and active WhatsApp application on smartphone, who started fixed orthodontic treatment with conventional ligation brackets (MBT technique) were included. Randomization Intervention: all participants received verbal oral hygiene instructions, were randomly assigned by software to the mobile app group (GAM) (n=30) (mean-----DE---- years) that used WhatsApp to reinforce oral hygiene, or to the control group (CG) (n=30) (mean-----DE---- years). The primary outcome was bacterial plaque level determined with the orthodontic plaque index (OPI) and bleeding on probing (BOP) index measured at three points, after appliance cementation (T0), 1 month later (T1), 2 months later (T2) and 3 months later (T3). Blinding: By two trained operators and blinded to the assignment. The secondary outcome was the identification of microorganisms in the bacterial plaque of the bracket ligation. The data were analyzed by

NCT ID: NCT05450588 Not yet recruiting - Obesity Clinical Trials

Development and Validation of Equations to Evaluate Body Composition in Colombian Population - F20 Project

Start date: March 2024
Phase:
Study type: Observational

The assessment of body composition is one of the main components within the evaluation of nutritional status under the ABCDE model. Generally, the use of equations to estimate components is a frequent strategy since it represents a doubly indirect method that has good correlation with methods of higher sensitivity (i.e., NMR, DXA, etc.). In this sense, the waist girth or circumference (WC) represents a quick, simple and inexpensive tool to evaluate the excess of fat mass in the human being; however, this measurement does not provide information on body composition in isolation and has been used as an important independent variable in some recent equations (e.g., relative fat mass [RFM]). Considering the lack of formulas or external validation of RFM in the Colombian population, the aim of this STROBE-Nut-based cross-sectional study is to develop and validate simple equations that use WC as an independent variable to estimate fat mass and fat-free mass in a population with different physical activity levels.

NCT ID: NCT05315388 Not yet recruiting - Anxiety Clinical Trials

Effects of "Vitamin N" Nature Immersion Therapy on Stress Levels in Health Care Workers in the City of Bogotá

Start date: October 15, 2022
Phase: N/A
Study type: Interventional

Recent studies on health personnel in Colombia have evidenced the considerable increase in the levels of stress and anxiety, among other psychological disorders, as a product of the COVID-19 pandemic that is being experienced since 2019 and that implies a greater demand for attention from the affected citizens, with the consequent work overload and tension due to the risk of contagion. Thus, the present work will allow the generation of new knowledge in relation to the benefits of Vitamin N therapy in Colombia; which can contribute quickly and effectively to the reduction of stress levels, anxiety, insomnia, and depression in individuals, when compared with conventional interventions and result in possible benefits such as the reduction of health problems such as obesity, diabetes, high blood pressure, and diseases associated with the immune system.

NCT ID: NCT04944823 Not yet recruiting - Covid19 Clinical Trials

Characterization Immunology, Biochemical and Lung Microbiome, Correlated With the Ventilation Associated Pneumonia (VAP)

MicroNAV-II
Start date: July 1, 2021
Phase:
Study type: Observational [Patient Registry]

SARS-CoV-2, the virus that causes COVID-19, is currently a global public health problem, declared a pandemic by the World Health Organization, which today has more than one million deaths in the world, of which , 30,000 approximately belong to Colombia, being the country number 11 with the highest number of deaths. The most common symptoms related to this disease are fever, cough, dyspnea, myalgia, headache, diarrhea and rhinorrhea. COVID-19 is characterized by immune system dysfunction and hyperinflammation causing acute respiratory distress syndrome, macrophage activation, and coagulopathy. The clinical course for SARS-CoV-2 in most cases is mild, but approximately 14% of cases can be severe. In pneumonia caused by SARS-CoV-2, the lung lining is known to alter the composition of the lung microbiome, in addition to lymphocyte damage that can promote the growth of bacteria to initiate bacterial pneumonia, and it is estimated that the prevalence of coinfection / superinfection reaches 50% among deaths from COVID-19. Coinfection between different microorganisms and SARS-CoV-2 is a serious problem in the COVID-19 pandemic, and there is still little information on this. It is for this reason that the researchs propose to develop this research project that will allow to understand the possible mechanisms associated with the development of bacterial coinfection / superinfection in patients diagnosed with COVID-19, which will allow expanding the panorama of knowledge towards a better and adequate treatment in these patients, as well as detection of biomarkers or clinical phenotypics that may be useful in the diagnosis, based on evidence. It is important to note that these results are of clinical importance since we will try to identify biomarkers or changes in the lung microbiome that allow doctors to early identify patients at risk of developing coinfection and thus initiate early treatments or preventive measures, which allow the improvement of clinical outcomes in patients. Results will be presented in a timely manner at national and international conferences and in peer-reviewed, indexed, high-impact journals.
