The brain mechanisms by which we transition from sleep to a conscious state remain largely unknown in humans, partly because of methodological challenges. Here we study a pre-existing dataset of waking up participants originally designed for a study of dreaming (Horikawa, Tamaki, Miyawaki, & Kamitani, 2013) and suggest that suddenly awakening from early sleep stages results from a two-stage process that involves a sequence of cortical and subcortical brain activity. First, subcortical and sensorimotor structures seem to be recruited before most cortical regions, followed by fast, ignition-like whole-brain activation-with frontal regions engaging a little after the rest of the brain. Second, a comparably slower and possibly mirror-reversed stage might take place, with cortical regions activating before subcortical structures and the cerebellum. This pattern of activation points to a key role of subcortical structures for the initiation and maintenance of conscious states.
Thoracic injury secondary to rib fractures following motor vehicle collisions (MVCs) significantly contribute to morbidity and mortality. While obesity has reached epidemic proportions, little is known regarding how BMI impacts outcomes in MVCs. The aim of this study was to examine how BMI impacts outcomes in MVC patients with rib fractures.
The ACS-TQIP Database was utilized to evaluate adult MVC patients with ≥3 rib fractures. Patients with a non-thoracic AIS ≥3 were excluded, to focus on chest injuries. Patients were sorted according to the presence or absence of flail chest injuries and BMI into groups with a low (<15), intermediate (15-24), or severe (≥25) ISS.
Overweight and obese patients in the non-flail cohort had decreased odds of pneumothorax in all ISS groups (P < 0.05). Overweight (P=0.049) and obese (P=0.011) patients in the low ISS non-flail cohort had decreased odds of splenic laceration. In the non-flail cohort, obese patients with a low and intermediate ISS had decreased odds of pulmonary contusion (P < 0.01). Eganelisib Obese patients in the low and intermediate ISS non-flail cohorts had increased odds of PE (P < 0.05). In both the flail and non-flail cohorts, obese patients with an intermediate ISS had decreased odds of liver laceration (P < 0.05), as well as a longer HLOS, ICU-LOS, and mechanical ventilation time (P < 0.01).
Obesity affects associated injuries, complications, and hospital outcomes in a complex way after MVC related chest wall trauma. Thus, the effect of BMI should be taken into consideration when assessing and treating obese MVC trauma patients.

Pediatric surgeons are often asked to treat clinical problems for which little high-quality data exist. For adults with adhesive small bowel obstruction (ASBO), water soluble contrast-based protocols are used to guide management. Little is known about their utility in children. We aimed to better understand key factors in clinical decision-making processes and integration of adult based data in pediatric surgeon's approach to ASBO.
We administered a web-based survey to practicing pediatric surgeons at institutions comprising the Western Pediatric Surgery Research Consortium.
The response rate was 69% (78/113). Over half of respondents reported using contrast protocols to guide ASBO management either routinely or occasionally (n=47, 60%). Common themes regarding the incorporation of adult-based data into clinical practice included the need to adapt protocols for pediatric patients, the dearth of pediatric specific data, and the quality of the published adult evidence.
Our findings demonstrate that pediatric surgeons use contrast-based protocols for the management of ASBO despite the paucity of pediatric specific data. Furthermore, our survey data help us understand how pediatric surgeons incorporate adult based evidence into their practice.

Inflammation of diverticula, which are outpouchings of the colonic bowl wall, causes diverticulitis. Severe cases of diverticulitis require surgical intervention. Through RNA-seq analysis of intestinal tissues, we previously found that the innate immune response was deregulated in surgical diverticulitis patients. In that study, pro-inflammatory and macrophage markers were differentially expressed in the colons of diverticulitis versus control patients. Here we investigate CD163L1
macrophages and the pro-inflammatory chemokine, CXCL10, in diverticulitis.
We assessed tissue from an uninvolved area adjacent to a region of the sigmoid colon chronically affected by diverticulitis and performed Spearman's correlation on transcripts associated with macrophage signaling. We identified altered CD163L1 and CXCL10 gene expression levels that we confirmed by RT-qPCR analysis on an independent cohort of diverticulitis patients and controls. We used immunofluorescence microscopy to localize CD163L1
macrophages and aid in clinical decision making for diverticulitis patients.
Anastomotic leakage (AL) is a common and severe complication after upper gastrointestinal (UGI) surgery. Although evidence is scarce, endoscopic deployed self-expanding metal stents (SEMS) are well-established for the management of AL in UGI surgery. The present study aimed to evaluate the feasibility, effectiveness, and safety of SEMS in terms of success, mortality, and morbidity in patients with AL after UGI cancer surgery.
Patients with AL after primary UGI cancer surgery were retrospectively analyzed with regard to demographics, disease, surgical and endoscopic procedures, and complications. Stent treatment success was divided into technical, primary (within 72 hours of stent deployment), sustained (after 72 hours of stent deployment), and sealing success.
In a total of 63 patients, 74 stents were used and 11 were deployed in endoscopic reinterventions. Stent deployment was successful in all patients. Primary and sustained success rates were 68.3% (n = 43) and 65.1% (n = 41), respectively. Of the primarily successfully treated patients, 87.
