Wound Healing in Healthy Volunteers

Wound Healing

The skin plays a critical role in protection where it acts as a barrier from damage and pathogens between the external and internal environments. Wounds compromise its protective role by disrupting the function and the normal structure of the skin and the underlying soft tissue. As a response to injury wound healing occurs in order to rapidly restore the defect. This process involves activation of keratinocytes, fibroblasts, endothelial cells, macrophages, and platelets and consists of multiple phases including hemostasis, inflammation, migration and cellular proliferation, and maturation and remodeling. A simplified schematic of the course of wound healing is depicted in Figure 2. Hemostasis occurs immediately after dermal injury. The inflammation phase is characterized by cellular recruitment and increased vascular permeability. The epithelization phase is achieved by proliferation of basal cells and migration of epithelial cells. The last phase is known as the maturation and remodeling phase where collagen cross-linking and remodeling, wound contraction, and repigmentation takes place. Due to the broad involvement of various cell types, extracellular matrix and many reactive molecules each phase in wound healing produces characteristic changes within the tissue. A deficiency in any part of the process can lead to delayed wound healing, abnormal scar formation or chronic wounds. To study wound healing in healthy volunteers a challenge model with skin punch biopsies has been described in literature previously. However, the characterization of this model was not performed comprehensively since advanced analysis of biopsies were omitted. Furthermore, analyses performed in previous studies only partially described wound healing processes either by insufficient time points for characterization or scarce simultaneous evaluations of multiple wound healing modalities. The overall aim of this study is to develop a standardized model to temporarily and locally induce a skin trauma to investigate wound healing and monitor wound closure. This clinical model will enable future application as proof-of-pharmacology and proof-of concept studies as well as drug profiling in early drug development programs. More specifically, the objective of the trial is to explore and characterize the induction of well-defined skin trauma and natural wound healing process over the course of the different phases using a battery of dermatological assessments after skin punch biopsies in healthy volunteers. Furthermore, safety and tolerability will be assessed. Characterization and monitoring of wound healing effects following skin punch biopsies will be performed by means of biophysical, biochemical, imaging, clinical parameters and subject reported outcomes.

The Effectiveness of a Running-related Injury Prevention Program in Runners

Running-related Injuries

Running is effective in increasing levels of physical activity and promotes a number of beneficial health effects. However, running can lead to running- related injuries (RRI). In theory, such injuries can be avoided with the implementation of prevention programs. But in practice, there is a paucity of prevention programs that are effective in reducing the risk of RRIs. In a previous study, the investigators developed an RRI prevention program using the Intervention Mapping framework. The RRI prevention program was named RunIn3. The present study will evaluate the effectiveness of the RunIn3 RRI prevention program. Objective: To investigate the effectiveness of an RRI prevention program (i.e., RunIn3). There will be recruited 530 runners of the state of São Paulo aged 18 years or older. After inclusion, participants will be randomly assigned and allocated in two groups: (1) intervention group, which will be the target of the implementation of the RunIn3 prevention program; and (2) control group, which will receive a minimal intervention (i.e., feedback based on surveillance).

Return to Baseball After BFR Therapy for Shoulder Injury

Musculoskeletal Injury

The literature is limited on whether BFR therapy provides improved return to function after acute rotator cuff or biceps rehabilitation in non-operative cases, and whether there is a clear mechanism of action in musculotendinous repair after BFR therapy. The purpose of the study is to 1) evaluate patient reported outcomes and return to play in baseball athletes undergoing rehabilitation with blood flow restriction (BFR) therapy for shoulder injury and 2) evaluate changes in blood biomarkers to assess the mechanism of action of BFR therapy in injured athletes. Investigators will perform a randomized blinded placebo-controlled trial of 2 separate study populations: 1) baseball players with biceps or rotator cuff tendinopathy undergoing non-operative treatment with BFR therapy incorporated into routine physical rehabilitation and 2) baseball players with biceps or rotator cuff tendinopathy undergoing non-operative treatment with routine physical rehabilitation alone. Primary outcomes will be functional outcomes and evaluation of return to sport. Functional outcomes will be evaluated using validated patient reported outcome surveys that are upper extremity-specific. Return to sport will be assessed by evaluating time to receiving clearance for returning to routine practices and reported level of physical performance and re-injury. Secondary outcomes will be measurement in muscle strength and blood biomarkers, as well as evaluation of 3D throwing motion. Strength will be measured using a biodex system at baseline prior to beginning physical rehabilitation, half-way through the rehabilitation protocol +/- BFR phase, and once cleared for return to play. Blood biomarkers GH, IGF-I, and IL-6 will be quantified at the same time points in order to investigate the mechanism of action of BFR on tissue repair. Patients will be followed longitudinally during this time for rates of reinjury.

Effects of Intraoperative Fluid Therapy on Acute Kidney Injury After Thoracoscopic Lobectomy

Acute Kidney Injury

Background: Acute kidney injury (AKI) often occurs after thoracoscopic lobectomy in high risk patients. Insufficient intraoperative infusion is risk factor of AKI. Goal-directed fluid therapy (GDFT) is individualized fluid infusion strategy, the infusion rate and type is adjusted according to the individual's fluid response. GDFT during operation can reduce the incidence of AKI after major surgery. Enhanced recovery after surgery (ERAS) integrates a range of perioperative interventions to decrease postoperative complications after surgery. In ERAS protocol of lobectomy, restrictive fluid therapy during operation is recommended. In this study, the investigators will compare the effects of GDFT and restrictive fluid therapy during operation combined with ERAS protocol on the incidence of AKI after thoracoscopic lobectomy in high risk patients. Methods/design: This is prospective single-center single-blind randomized controlled trial. 276 patients scheduled to undergo thoracoscopic lobectomy under general anesthesia combined with paravertebral block are randomly divided into GDFT group and restrictive fluid therapy group at a 1:1 ratio. The primary outcome is the incidence of AKI after operation. The secondary outcomes are (1) the incidence of renal replacement therapy, (2) length of intensive care unit (ICU) stay after operation, (3) length of hospital stay after operation , (4) incidence of other complications including: infection, acute lung injury (ALI), pneumonia, arrhythmia, heart failure, myocardial injury after noncardiac surgery (MINS), cardiac infarction. Discussion: This is the first study to compare GDFT and restrictive fluid therapy during operation combined with ERAS protocol on the incidence of AKI after thoracoscopic lobectomy in high risk patients. The investigators expected that the two methods have the same effect on the incidence of AKI, but restrictive fluid therapy is simpler to applied than GDFT.

Spectral Correlates of Impulsivity in Patients With Traumatic Brain Injury

Traumatic Brain Injury

Transcranial electrical stimulation (tES) is a non-invasive form of brain stimulation that has previously been to shown to have therapeutic potential in traumatic brain injury (TBI) patients. In this study, the study team will use a brain activity monitor (electroencephalogram, EEG) and a computer-based task to observe the effects of different forms of tES, like transcranial direct current stimulation (tDCS) and transcranial pulsed current stimulation (tPCS), on impulse control and sustained attention in people with TBI. Additionally, the study team will measure how much tDCS and tPCS affect the brain activity of a specific area of the brain associated with impulse control and attention. Problems with response inhibition have been shown to make rehabilitation more difficult for people with TBI. It also reduces social functioning and can also negatively affect job performance, which ultimately lead to a decreased quality of life. A better understanding of the effects of tES in TBI patients could be informative in finding out what its therapeutic potential is for this population.

Thromboembolic Risk Stratification by TRiP(Cast) Score to Guide Physicians in Preventive Treatment...

Lower Limb TraumaVenous Thromboembolism1 more

Non-surgical traumas to the lower limbs that require orthopedic immobilisation (plaster or splint) are a frequent reason for going to accident and emergency. Due to venous stasis caused by immobilisation, hypercoagulable states and vascular injuries brought on by the trauma, these patients are at risk of developing VTE. For this reason, it is current practice in France and Belgium for the majority of patients to receive a preventative anticoagulant treatment. However, the benefit of this treatment, which has a considerable cost, is controversial. Contrary to French recommendations, American recommendations from 2012 actually advise against systematic preventative medicine, with prevention appearing to be effective primarily in studies with restrictive inclusion criteria. The most significant randomised controlled study on the subject did not show the benefit of low-molecular-weight heparin (LMWH) on the rate of symptomatic VTE among 1,435 non-selected patients. Therefore, in 2017, the Cochrane meta-analysis concluded that stratification of the risk of thromboembolism is required. For this purpose, in collaboration with the Dutch team of Nemeth et al. we have recently developed a risk stratification model that takes into consideration the patient's characteristics, the type of immobilisation and the severity of the trauma: the TRiP(cast) score. This score is applied retrospectively to a large cohort and demonstrates excellent prognostic performances (AUC (area under the curve) of 0.74). In addition, when using a <7 limits, it makes it possible to identify a large group of patients at very low risk of developing VTE (negative predictive value: 99.2%). The aim of the CASTING study is to prospectively demonstrate the reliability and utility of the TRiP(cast) score by showing that patients with orthopaedic immobilisation of a lower limb who are not receiving preventative treatment on the basis of a TRiP(cast) score of <7 have a very low rate of symptomatic VTE, which allows for a significant reduction in prescriptions of anticoagulants in comparison with prior practices.
