Filter by:This study is to build a microbiome cohort by collecting sputum and fecal samples every few months for three years from healthy smokers and chronic obstructive pulmonary disease (COPD) patients. The aim of this study is to analyze the composition of microbiome of various samples (e.g. sputum, feces) and describe the difference between healthy smokers and COPD patients.
Aim of the study 1. Estimate the prevalence of intraoral injection fear and its relationship to dental fear among 8-10 years children. 2. Explore the possible consequences of such problems in terms of avoidance of dental and medical care.
Weight loss and lifestyle modifications are much required in women with Polycystic ovarian syndrome (PCOS). Yoga has gained great importance as an alternate medicine in recent years which is helpful in lifestyle modifications. Weight loss can be achieved by regular aerobic activity. In recent years, excessive production of anti-mullerian hormone (AMH) has been considered as the etiology of PCOS. AMH is also emerging as a diagnostic and screening tool for PCOS. Effect of yoga therapy on adolescent girls have proved to be effective. But, researches on young women undergoing yoga therapy and combined effect of aerobic exercise and yoga therapy are still lacking. Hence, the investigators aimed t o establish the benefits of yoga therapy and aerobic exercise on Anti-Mullerian Hormone and other biochemical markers in young women with polycystic ovary syndrome.
The aim of this study is to compare the effectiveness of Clear aligners and Conventional braces for upper canine retraction (space closure) regarding canine tipping , anchorage loss and treatment time.
To study the effects of probiotic supplement in children with Attention-deficit hyperactivity disorder (ADHD),40 patients will be randomly allocated to two groups of intervention and placebo. The intervention and the placebo group will be prescribed with 1 capsule of probiotics and placebo for 8 weeks, respectively. Treatment efficacy will be assessed via administrating the Conners's rating
Background: A novel Coronavirus (SARS-CoV-2) described in late 2019 in Wuhan, China, has led to a pandemic and to a specific coronavirus-related disease (COVID-19), which is mainly characterized by a respiratory involvement. While researching for a vaccine has been started, effective therapeutic solutions are urgently needed to face this threaten. The renin-angiotensin system (RAS) has a relevant role in COVID-19, as the virus will enter host 's cells via the angiotensin-converting enzyme 2 (ACE2); RAS disequilibrium might also play a key role in the modulation of the inflammatory response that characterizes the lung involvement. Angiotensin-(1-7) is a peptide that is downregulated in COVID-19 patient and it may potentially improve respiratory function in this setting. Methods/Design: The Investigators describe herein the methodology of a randomized, controlled, adaptive Phase II/Phase III trial to test the safety, efficacy and clinical impact of the infusion of angiotensin-(1-7) in COVID-19 patients with respiratory failure requiring mechanical ventilation. A first phase of the study, including a limited number of patients (n=20), will serve to confirm the safety of the study drug, by observing the number of the severe adverse events. In a second phase, the enrollment will continue to investigate the primary endpoint of the study (i.e. number of days where the patient is alive and not on mechanical ventilation up to day 28) to evaluate the efficacy and the clinical impact of this drug. Secondary outcomes will include the hospital length of stay, ICU length of stay, ICU and hospital mortality, time to weaning from mechanical ventilation, reintubation rate, secondary infections, needs for vasopressors, PaO2/FiO2 changes, incidence of deep vein thrombosis, changes in inflammatory markers, angiotensins plasmatic levels and changes in radiological findings. The estimated sample size to demonstrate a reduction in the primary outcome from a median of 14 to 11 days is 56 patients, 60 including a dropout rate of 3% (i.e. 30 per group), but a preplanned recalculation of the study sample size is previewed after the enrollment of 30 patients. Expected outcomes/Discussion: This controlled trial will assess the efficacy, safety and clinical impact of the Angiotensin-(1-7) infusion in a cohort of COVID-19 patients requiring mechanical ventilation. The results of this trial may provide useful information for the management of this disease.
Diet is known to play role in the complex etiology of UC.Patient with UC tend to adapt unguided dietary habits without the guidance of a dietician or physician (Dejong,M.J 2019).so identification of nutritional gaps is needed to facilitate the development of evidence-based dietary guideline and subsequently give correct dietary advice to UC patients(Haskkey,N et al 2017).
Immune-mediated lung injury plays a pivotal role in severe interstitial pnemumonia related to SARS-CoV2 infection. Tofacitinib, a JAK1/3-Inhibitor, could mitigate alveolar inflammation by blocking IL-6 signal. The aim of this prospective single cohort open study is to test the hypotesis that early administration of tofacitinib in patients with symptomatic pneumonia could reduce pulmonary flogosis, preventing function deterioration and the need of mechanical ventilation and/or admission in intensive care units.
This is a dose escalation study based on 3+3 design with the aim to establish MTD and provide RP2D. PLM60 is to administered by multi-cycle intravenous infusion.
In recent years, immunotherapy research has made great progress, especially the immunocheckpoint inhibitors represented by anti-pd-1 antibody have shown good efficacy in the treatment of malignant tumors, and some patients can achieve long-term survival. However, despite the encouraging clinical data, only a small number of people have benefited. Therefore, how to further improve the efficacy of immunotherapy and expand the benefit population has become the focus of this field. The applicant was previously published in Oncoimmunology (2017; E1331807) pointed out in the above article: MDSC is a group of immunosuppressive cells, the number of this group of cells in the body of cancer patients is more than normal, its presence affects the proliferation, activation and function of T cells, is one of the important factors affecting the efficacy of immunocheckpoint inhibitors. Therefore, ideal drugs used in combination with immunocheckpoint inhibitors should meet the following conditions: first, they can kill or inactivate tumor cells to release tumor-specific or associated antigens; Second, MDSC and other immunosuppressive cells can be eliminated. Third, the number and function of T cells were not affected. Gemcitabine is a synthetic antimetabolic tumor drug widely used in the treatment of locally advanced or metastatic non-small cell lung cancer. Myelosuppression is the dose - limiting toxicity of gemcitabine, which includes lymphocytopenia. Therefore, if the commonly used clinical dose gemcitabine is used in combination with pd-1 antibody, the effect of pd-1 antibody will be affected due to the reduction of lymphocytes caused by gemcitabine. Therefore, we speculated that the reduced-dose treatment of gemcitabine combined with pd-1 antibody might have synergistic anti-tumor effect on the second-line and above second-line treatment of non-small cell lung cancer with negative driver gene, and the adverse reactions were relatively mild. This study is a phase IV, open, non-randomized, single-arm, single-center study to investigate the safety and efficacy of half-dose gemcitabine combined with pd-1 antibody in second-line and above treatment of non-small cell lung cancer patients with negative driver genes. Fifty subjects will be enrolled in this study. The primary endpoint of the study was ORR, while secondary endpoints included DCR, PFS, and OS.
