CONCLUSIONS Our current analysis suggested that MTHFR rs1801131 A/C is associated with urinary cancers, especially bladder cancer.BACKGROUND Hydrops fetalis as well as abdominal compartment syndrome (ACS) are conditions that are associated with high mortality rates. A rare case of immature gastric teratoma causing fetal hydrops and subsequent ACS is presented. The related pathophysiologic mechanisms are discussed, and the importance of timely recognition and appropriate interventions are highlighted. CASE PRESENTATION The male patient was born preterm, weighing 3.9 kg., by Cesarean section. Prior prenatal ultrasounds were normal, but a scan done just before delivery had findings indicating polyhydramnios, fetal ascites, and meconium peritonitis. Upon delivery, the patient had respiratory distress, anasarca and a massively distended abdomen. Resuscitation measures, including ventilatory support, were instituted. Imaging studies showed ascites as well as a large, complex intra-abdominal lesion with calcifications. In the succeeding hours, anuria persisted, anasarca worsened, the abdomen became more distended, and inotrope requirements increased. The occurrence of ACS, from what was presumed to be a retroperitoneal teratoma, was therefore considered. Laparotomy was done on the 28th hour of life, with en bloc excision of a massive tumor and attached section of the greater curvature of the stomach. Passage of urine occurred intra-operatively, and the patient was soon after weaned off inotropes and ventilator support. The histopathologic result was immature gastric teratoma. No chemotherapy was given, and the patient's serum AFP is at normal levels 15 months following surgery. CONCLUSION The presence of a massive intra-abdominal lesion can result in the pathophysiologic continuum of hydrops fetalis and neonatal ACS. The early recognition of such an association can enable appropriate expectant management of similarly affected neonates, including emergent decompression laparotomy.BACKGROUND In children and adolescents, anxiety disorders (ADs) are among the most prevalent mental disorders. While there is a solid empirical foundation to support CBT as an evidence-based treatment for childhood ADs, the mechanisms underlying the efficacy of CBT are not well explored. Exposure is assumed to be vital to the efficacy of CBT in ADs, but empirical evidence (e.g., dismantling studies) showing that exposure is indeed a vital element of effective treatments is relatively scarce. The proposed meta-analysis aims to investigate the role of exposure in reducing symptoms of anxiety among children and adolescents. METHODS A systematic search of several electronic databases including PubMed/MEDLINE, PsycINFO, Psyndex plus, Web of Science, Scopus, and EMBASE will be conducted (from inception onwards). We will include randomized and non-randomized clinical trials examining exposure and anxiety among children and adolescents. If feasible, we will also include experimental, quasi-experimental, and observatiCRD42019128667).INTRODUCTION The performance of tracheotomy is a common procedural request by critical care departments to the surgical services of general surgery, thoracic surgery and otolaryngology - head & neck surgery. A Canadian Society of Otolaryngology - Head & Neck Surgery (CSO-HNS) task force was convened with multi-specialty involvement from otolaryngology-head & neck surgery, general surgery, critical care and anesthesiology to develop a set of recommendations for the performance of tracheotomies during the COVID-19 pandemic. MAIN BODY The tracheotomy procedure is highly aerosol generating and directly exposes the entire surgical team to the viral aerosol plume and secretions, thereby increasing the risk of transmission to healthcare providers. As such, we believe extended endotracheal intubation should be the standard of care for the entire duration of ventilation in the vast majority of patients. Pre-operative COVID-19 testing is highly recommended for any non-emergent procedure. CONCLUSION The set of recommendations in this document highlight the importance of avoiding tracheotomy procedures in patients who are COVID-19 positive if at all possible. Recommendations for appropriate PPE and environment are made for COVID-19 positive, negative and unknown patients requiring consideration of tracheotomy. The safety of healthcare professionals who care for ill patients and who keep critical infrastructure operating is paramount.BACKGROUND Traumatic brain injury (TBI) is among the most prevalent causes of cerebrovascular and neurological damage worldwide. To this end, tobacco smoke (TS) has been shown to promote vascular inflammation, neurovascular impairments, and risk of cerebrovascular and neurological disorders through oxidative stress (OS) stimuli targeting the blood-brain barrier (BBB) endothelium among others. It has been recently suggested that premorbid conditions such as TS may exacerbate post-TBI brain damage and impact recovery. METHODS Our study investigated the mechanisms underlying the exacerbation of TBI injury by TS using a weight drop model. For this purpose, male C57BL/6J mice, age range 6-8 weeks, were chronically exposed to premorbid TS for 3 weeks. Test animals were then subjected to TBI by guided vertical head weight drop using a 30 g metal weight free felling from an 80 cm distance before reaching the target. We analyzed the physical activity and body weight of the mice before TBI and 1 h, 24 h, and 72 h post--inflammatory response to TBI leading to worsening impairments of the BBB, OS damage, and inflammation. These factors are also likely responsible for the retardation of post-traumatic recovery observed in these animals.BACKGROUND Pulmonary hypertension leads to right ventricular heart failure and ultimately to cardiac cachexia. Androgen Receptor Antagonist Cardiac cachexia induces skeletal muscles atrophy and contractile dysfunction. MAFbx and MuRF1 are two key proteins that have been implicated in chronic muscle atrophy of several wasting states. METHODS Monocrotaline (MCT) was injected over eight weeks into mice to establish pulmonary hypertension as a murine model for cardiac cachexia. The effects on skeletal muscle atrophy, myofiber force, and selected muscle proteins were evaluated in wild-type (WT), MuRF1, and MuRF2-KO mice by determining muscle weights, in vitro muscle force and enzyme activities in soleus and tibialis anterior (TA) muscle. RESULTS In WT, MCT treatment induced wasting of soleus and TA mass, loss of myofiber force, and depletion of citrate synthase (CS), creatine kinase (CK), and malate dehydrogenase (MDH) (all key metabolic enzymes). This suggests that the murine MCT model is useful to mimic peripheral myopathies as found in human cardiac cachexia.
