The lower MAP was associated with a dramatic fall in systemic vascular resistance and improved oxygen delivery. ALM drip significantly increased cardiac output and stroke volume with lower dP/dtMin, indicating a less stiff heart. ALM drip also significantly decreased cerebral perfusion pressure, reduced cerebral oxygen consumption (28%), and reduced brain glycerol (60%), lactate (47%), and relative expression of hypoxia-inducible factor (38%) compared with saline controls. CONCLUSIONS ALM therapy improved cardiac function and oxygen delivery by lowering systemic vascular resistance after noncompressible hemorrhage. ALM also appeared to protect the brain at hypotensive MAPs with significantly lower cerebral perfusion pressure, lower O2 consumption, and significantly lower cortical lactate and glycerol levels compared to saline controls. BACKGROUND With the widespread use of advanced imaging there is a need to quantify the prevalence and impact of hernias. We aimed to determine the prevalence of abdominal wall hernias among patients undergoing computed tomography (CT) scans and their impact on abdominal wall quality of life (AW-QOL). METHODS Patients undergoing elective CT abdomen/pelvis scans were enrolled. Standardized physical examinations were performed by surgeons blinded to the CT scan results. AW-QOL was measured through the modified Activities Assessment Scale. On this scale, 1 is poor AW-QOL, 100 is perfect, and a change of 7 is the minimum clinically important difference. Three surgeons reviewed the CT scans for the presence of ventral or groin hernias. The number of patients and the median AW-QOL scores were determined for three groups no hernia, hernias only seen on imaging (occult hernias), and clinically apparent hernias.

Physical examination detected 62 (25.2%) patients with a hernia while CT scan revealed 107 (43.5%) with occult hernias. The median (interquartile range) AW-QOL of patients per group was no hernia&nbsp;=&nbsp;84 (46), occult hernia&nbsp;=&nbsp;77 (57), and clinically apparent hernia&nbsp;=&nbsp;62 (55). CONCLUSIONS One-fourth of individuals undergoing CT abdomen/pelvis scans have a clinical hernia, whereas nearly half have an occult hernia. Compared with individuals with no hernias, patients with clinically apparent or occult hernias have a lower AW-QOL (by 22 and seven points, respectively). Further studies are needed to determine natural history of AW-QOL and best treatment strategies for patients with occult hernias. BACKGROUND Pleuropulmonary blastoma (PPB) is the most common primary lung cancer in children. While rare, these tumors are highly aggressive. Tumor recurrence and overall survival are dependent on histologic grade and extent of surgical resection. We sought to examine our institutional experience with PPB to determine the effect of gross total resection (GTR) on recurrence and patient outcomes. MATERIALS AND METHODS After IRB approval, a retrospective chart review from 1998 to 2018 was performed. Cases were confirmed by histology and Dehner Grade (I to III). Data collection included demographics, treatment, extent of surgical resection, and patient outcomes. RESULTS Eight patients with nine procedures were identified. Histologically, three cases were type 1, 2 type 2, and four poor prognosis type 3. Three patients received neoadjuvant chemotherapy to facilitate surgical resection. The operative goal was to achieve GTR (&gt;95%), and to this end, three partial lobectomies, five lobectomies, and one pneumonectomy were performed. All nine cases achieved GTR, of which eight had negative microscopic margins. Two patients with type III disease recurred (one locally, one distant) and died. One type 3 patient had a positive microscopic hilar margin not amenable to further resection. The patient recurred (distant) but is in remission. With respect to patient outcomes, the event-free survival was 2.3&nbsp;y with an overall survival of 3.3&nbsp;y. CONCLUSIONS From our experience, GTR of PPB is associated with minimal surgical morbidity and good overall survival. Multi-institutional studies are needed to determine if positive surgical margins affect outcomes given the morbidity of mediastinal dissection. This study examined the feasibility, acceptability, and preliminary efficacy of a decision rule driven treatment for youth with comorbid conduct problems and depression. A randomized, controlled, repeated measures design was used to compare two treatment approaches Decision-Rule Based Treatment (DR) and Sequential Treatment (SEQ). Participants included 30 children (ages 8-14; 66% female; 80% Caucasian) who met criteria for a depressive disorder (major depressive disorder and/or dysthymia) and a conduct problem disorder (oppositional defiant disorder and/or conduct disorder). Assessments were conducted at baseline, post-treatment, and six-month follow-up. Treatment adherence, attendance, and session evaluations ratings indicate that the treatments were feasible to implement and acceptable to parents and youth in both conditions. Both treatments showed similar remission of internalizing and externalizing diagnoses. Participants in DR showed significantly greater improvements at six-month follow-up in child-reported depressive symptom severity compared to SEQ. Both DR and SEQ conditions showed significantly lower behavior problems at end of treatment and six-month follow-up. DR showed significant reductions in emotion dysregulation at 6-month follow-up, while SEQ did not. Findings suggest that a decision rule based intervention holds promise as a feasible and acceptable treatment with high rates of remittance. The novel coronavirus SARS-CoV2 causes COVID-19, a pandemic threatening millions. As protective immunity does not exist in humans and the virus is capable of escaping innate immune responses, it can proliferate, unhindered, in primarily infected tissues. Subsequent cell death results in the release of virus particles and intracellular components to the extracellular space, which result in immune cell recruitment, the generation of immune complexes and associated damage. Infection of monocytes/macrophages and/or recruitment of uninfected immune cells can result in massive inflammatory responses later in the disease. Uncontrolled production of pro-inflammatory mediators contributes to ARDS and cytokine storm syndrome. Antiviral agents and immune modulating treatments are currently being trialled. Understanding immune evasion strategies of SARS-CoV2 and the resulting delayed massive immune response will result in the identification of biomarkers that predict outcomes as well as phenotype and disease stage specific treatments that will likely include both antiviral and immune modulating agents.
