Prospective, non-equality, cohort study, where investigators propose to analyze humoral and cellular immunity after two doses of SARS-CoV-2 RNA vaccines in HIV-infected participants severely immunosuppressed. A total of 92 HIV-infected subjects over 18 years old with ≤200 CD4/μl (experimental group; n=46) and ≥ 350 CD4/μl (as control group; n=46) who have completed two doses vaccination against SARS-CoV-2 will be included in the study. Primary Objectives: - To analyze the percentage of participants with SARS-CoV-2-specific IgG after 1, 6, and 12 months after vaccination in subjects with ≤200 vs ≥350 CD4/μL by electrochemiluminescence immunoassay (Elecsys® Anti-SARS-CoV-2. Roche Diagnostics). - To analyze the percentage of subjects with specific T and memory B lymphocyte response against SARS-CoV-2 after 1, 6, and 12 months after vaccination with <200 vs ≥350 CD4/μL. Multiparametric flow cytometry in peripheral blood mononuclear cells (PBMCs) will be performed to detect the production of cytokines (IL-2, TNF-α and IFN-γ), cytolytic (perforin and granzyme B) and degranulation (CD107a) molecules from T cells, as well as to identify memory B cells specific to SARS-CoV-2 IgG+. Secondary Objectives: To analyze in participants with <200 vs ≥350 CD4/μl after 1, 6, and 12 months after vaccination: - Quantification of specific IgG titers against SARS-CoV-2 - The association of the T response to SARS-CoV-2 with humoral response parameters. - The association of the T response against SARS-CoV-2 with other parameters of immune activation, inflammation and immunosenescence. The phenotypes of maturation (CD45RA and CD27), activation (HLA-DR and CD38), senescence (CD57+CD28-) and markers of immune exhaustion (TIGIT, LAG-3, TIM-3 and PD-1) in CD4 and CD8 lymphocytes T will be determined by multiparametric flow cytometry.
The overall objective of STOP-FALLS is to test whether a patient-centered deprescribing intervention that focuses on CNS-active medications reduces medically treated falls among older adults. Our aims are: AIM 1: Adapt and pilot-test an evidence-based medication reduction intervention for use in an integrated health care system. AIM 2: Implement and evaluate the adapted intervention using a cluster-randomized controlled trial design. Aim 3: Assess barriers and facilitators to intervention implementation.
To investigate the effect of Low Level Laser therapy on orthodontic tooth movement of periodontally compromised patients by evaluating the rate of orthodontic tooth movement and the level of Osteocalcin in the gingival crevicular fluid.
To develop this objective and easily implementable assessment method of coughing based on acoustic features of voluntary and reflex coughs, there is a primary need in identifying and comparing acoustic cough features in healthy subjects and different disease-related coughs features. Cough is a common reason for seeking medical care. Chronic cough, defined as a cough that has lasted for longer that eight weeks, represents 10-38% of all referrals made to respiratory physicians [1-2]. Furthermore, between 60 and 80% of patients with chronic obstructivepulmonary disease (COPD) report cough. Following this pilot study comparing different populations, the applicability of the selected acoustic cough features should be examined in HNC patients with radiotherapy-induced dysphagia, Another frequent aspect of the clinical diagnostic examination of swallowing is perceptual analysis of voice quality immediately following deglutition. Changes in voice quality are assumed to provide information on the possible accumulation of saliva or food at the vocal folds level. It is reported that a change of voice may indicate laryngeal dysfunction or the presence of a foreign body at the laryngeal level [3] confirm that a normophonic voice after swallowing reflects a lack of aspiration-penetration. However, research shows that there is no strong correlation between aspiration and changes in perceptual voice quality (e.g. wet voice). A more reliable and easily implementable method could be detection of specific acoustic features of changes in voice quality.
By the comparison of the preoperative and postoperative data of approximately 160 patients undergoing gastric sleeve surgery, we try to draw conclusions about the effectiveness of gastric sleeve surgery, expected complication rate.
This research concerns children with complex neuro-disability. Damage to the developing brain leads to lifelong disturbances in motor control, seizures, cognition, communication, eating and drinking, and behaviour. Children with complex neuro-disability are dependent upon others to move and position them. Children commonly experience chronic lung disease, leading to frequent hospitalisation, medical interventions and premature death. Respiratory illness may be triggered by "aspiration", i.e. when saliva, food, liquid or stomach contents enter the lungs. Aspiration risks increase at night-time when supervision is limited and children are positioned on their backs. Some children experience repeated breathing complications requiring prolonged hospital stays including respiratory support in intensive care. Consultant Respiratory Paediatrician Akshat Kapur and Physiotherapist Hilda Perry developed a new night-time intervention to improve respiratory health of children with complex neuro-disability. Dr Kapur and his team have found that this intervention can help reduce respiratory illness and time spent in hospital for some children. This is an acceptability and feasibility study which means the investigators want to find out if this new intervention is something that children with complex neuro-disability and their families are happy (i.e. it is acceptable) and able (i.e. it is feasible) to do. If so, a larger future research study can be designed to find out if the intervention works to improve the respiratory health of children with complex neuro-disability.
This study is a randomized controlled trial which compares the effect of vitamin D3 therapy 5,000 IU daily and 50,000 IU on 25(OH)D and 1,25(OH)2D, VDBP, and 24,25(OH)2D maternal serum levels in pregnant women with vitamin D deficient and insufficient.
The SMK project's primary goal is to improve the status of SRH of women and adolescents within those targeted areas which feature inadequate progress on existing SRH indicators. The focus remains on empowering increasingly marginalized and vulnerable populations to exercise their reproductive rights, free of coercion, discrimination and violence. This will be achieved through the implementation of evidence-based and socio-culturally sensitive FP/ SRH interventions within ten districts of Pakistan. The aim of this project is therefore to evaluate the impact of a package of community and facility-based interventions on improving the SRH/ FP of the targeted population. In order to achieves this, a quasi-experimental pre & post evaluation intervention study with a formative phase, baseline assessment, intervention phase and finally an end-line assessment, consisting of both qualitative & quantitative monitoring & evaluation tools will be applied at the household, community, healthcare facility and district levels in all project areas. Furthermore, descriptive statistics will be tabulated on key indicators and stratified on selected variables. Means for continuous variables and proportion for categorical variables will be calculated at a 95% confidence interval within this study
This study targets individuals in Chicago who have received naloxone administered by first responders within the past week to reverse an overdose, but who have not entered into MAT. Study participants will be recruited through partnerships with the Chicago Fire Department (CFD) and/or Police Department (CPD); first responders will be trained to seek consent from individuals who are alert and oriented after receiving naloxone for future contacts by research staff as part of the naloxone standard protocol. Those who consent will be contacted and screened for study eligibility ideally within one week of naloxone administration; eligible participants will be randomly assigned either to the control group, i.e., referral to MAT as usual, or to Recovery Initiation and Management after Overdose (RIMO), an assertive linkage and recovery support intervention. This intervention builds on an evidence-based intervention for treatment linkage, monitoring, and recovery support evaluated in 3 prior clinical trials by the study team.
