42 × 10-2 S m-1 when TCNQ is incorporated for 10 days. The conductivity of solution-sheared TCNQ@HKUST-1 is higher compared to films formed by high-pressure pelletization of TCNQ@HKUST-1. We show that solution shearing can produce large-area thin films rapidly and reduce the formation of grain boundaries better than pelletization, allowing for large-area electronics with both charge transport and porosity for applications as sensors and electronics.
The purpose of this study was to describe and analyze methods of bowel emptying among Germans living with spina bifida. We also analyzed relationships between age, sex, level of spinal bifida anomaly, and methods of bowel elimination.
A quantitative, descriptive study.
The sample comprised 88 persons (56 women and 32 men) residing anywhere in the Federal Republic of Germany. Their mean age was 17.5 years (SD 13.64 years), range 0 to 55 years.
Data were collected through an online survey questionnaire developed for the urological follow-up protocol for patients with spina bifida. Parents completed the questionnaire for participants younger than 18 years.
Twenty participants (22.7%) reported normal defecation and 68 (77.3%) reported neurogenic bowel dysfunction requiring regular bowel management. Participants requiring bowel management predominately used rectal irrigation (40.9%) and digital rectal stimulation (27.3%) to enhance bowel evacuation. Age emerged as the only factor related to the bowel manctal irrigation was the most common method for bowel evacuation. Participants were less likely to employ potentially effective and more conservative measures for intestinal emptying, such as toilet training/timed evacuation associated with Valsalva maneuvers, abdominal press, abdominal massage, and digital rectal stimulation. Additional comparative studies with more participants and other countries with intestinal emptying methods are needed to better understand the needs of individuals with spina bifida and their families and to improve the health-related quality of life of these people.
Despite strong recommendations, there is no direct evidence supporting routine intubation of trauma patients with Glasgow Coma Scale (GCS) score of 7 or 8. We hypothesized that routine intubation may not be beneficial in isolated blunt head injury.
A retrospective Trauma Quality Improvement Program study, including adult blunt trauma patients with GCS score of 7 or 8 and isolated head injury, was performed. Epidemiological and clinical characteristics, neurosurgical procedures, timing of intubation, and outcome variables were collected. The study population was stratified by the intubation procedure immediate intubation (≤1 hour of admission), delayed intubation (>1 hour of admission), and no intubation. Multivariable regression analysis was used to determine risk factors for mortality and complications, as well as factors predictive of the decision to intubate.
Of 2,727 patients with GCS score of 7 or 8 and isolated blunt head trauma, 1,866 patients (68.4%) were intubated within 1 hour of admission injury, immediate intubation was associated with higher mortality and more overall complications. Intubation management could have been improved by intubating all patients younger than 45 years with head AIS score of 5 and a GCS score of 7 on admission.

Despite major improvements in the United States trauma system over the past two decades, prehospital trauma triage is a significant challenge. Undertriage is associated with increased mortality, and overtriage results in significant resource overuse. The American College of Surgeons Committee on Trauma benchmarks for undertriage and overtriage are not being met. Many barriers to appropriate field triage exist, including lack of a formal definition for major trauma, absence of a simple and widely applicable triage mode, and emergency medical service adherence to triage protocols. Modern trauma triage systems should ideally be based on the need for intervention rather than injury severity. Future studies should focus on identifying the ideal definition for major trauma and creating triage models that can be easily deployed. This narrative review article presents challenges and potential solutions for prehospital trauma triage.

The aim of this systematic review was to assess the necessity of routine chest radiographs after chest tube removal in ventilated and nonventilated trauma patients.
A systematic literature search was conducted in MEDLINE, Embase, CENTRAL, and CINAHL on May 15, 2020. Quality assessment was performed using the Methodological Index for Nonrandomized Studies criteria. Primary outcome measures were abnormalities on postremoval chest radiograph (e.g., recurrence of a pneumothorax, hemothorax, pleural effusion) and reintervention after chest tube removal. Secondary outcome measures were emergence of new clinical symptoms or vital signs after chest tube removal.
Fourteen studies were included, consisting of seven studies on nonventilated patients and seven studies on combined cohorts of ventilated and nonventilated patients, all together containing 1,855 patients. Nonventilated patients had abnormalities on postremoval chest radiograph in 10% (range across studies, 0-38%) of all chest tubes and 24% (range, 0-78%) of those underwent reintervention. In the studies that reported on clinical symptoms after chest tube removal, all patients who underwent reintervention also had symptoms of recurrent pathology. Combined cohorts of ventilated and nonventilated patients had abnormalities on postremoval chest radiograph in 20% (range, 6-49%) of all chest tubes and 45% (range, 8-63%) of those underwent reintervention.
In nonventilated patients, one in ten developed recurrent pathology after chest tube removal and almost a quarter of them underwent reintervention. In two studies that reported on clinical symptoms, all reinterventions were performed in patients with symptoms of recurrent pathology. In these two studies, omission of routine postremoval chest radiograph seemed safe. However, current literature remains insufficient to draw definitive conclusions on this matter, and future studies are needed.

Surgical site infections (SSIs) are well-recognized complications after exploratory laparotomy for abdominal trauma; however, little is known about SSI development after exploration for battlefield abdominal trauma. We examined SSI risk factors after exploratory laparotomy among combat casualties.
Military personnel with combat injuries sustained in Iraq and Afghanistan (June 2009 to May 2014) who underwent laparotomy and were evacuated to participating US military hospitals were included. Log-binominal regression was used to identify SSI risk factors.
Of 4,304 combat casualties, 341 patients underwent a total of 1,053 laparotomies. Abdominal SSIs were diagnosed in 49 patients (14.4%) 8% with organ space SSI, 4% with deep incisional SSI, and 4% with superficial SSIs (4 patients had multiple SSIs). Patients with SSIs had more colorectal (p < 0.001), small bowel (p = 0.010), duodenum (p = 0.006), pancreas (p = 0.032), and abdominal vascular injuries (p = 0.040), as well as prolonged open abdomen (p = 0ow at 14%, with similar risk factors and rates reported following severe civilian trauma.

Access to pediatric trauma care is highly variable across the United States. The purpose of this study was to measure the association between pediatric trauma center care and motor vehicle crash (MVC) mortality in children (<15 years) at the US county level for 5 years (2014-2018).
The exposure was defined as the highest level of pediatric trauma care present within each county (1) pediatric trauma center, (2) adult level 1/2, (3) adult level 3, or (4) no trauma center. Pediatric deaths due to passenger vehicle crashes on public roads were identified from the NHTSA Fatality Analysis Reporting System. Hierarchical negative binomial modeling measured the relationship between highest level of pediatric trauma care and pediatric MVC mortality within counties. Adjusted analyses accounted for population age and sex, emergency medical service response times, helicopter ambulance availability, state traffic safety laws, and measures of rurality.
During the study period 3,067 children died in fatal crashes. W target for system-level improvement.

Intracranial pressure monitor (ICPm) procedure rates are a quality metric for American College of Surgeons trauma center verification. However, ICPm procedure rates may not accurately reflect the quality of care in TBI. We hypothesized that ICPm and craniotomy/craniectomy procedure rates for severe TBI vary across the United States by geography and institution.
We identified all patients with a severe traumatic brain injury (head Abbreviated Injury Scale, ≥3) from the 2016 Trauma Quality Improvement Program data set. Patients who received surgical decompression or ICPm were identified via International Classification of Diseases codes. Hospital factors included neurosurgeon group size, geographic region, teaching status, and trauma center level. Two multiple logistic regression models were performed identifying factors associated with (1) craniotomy with or without ICPm or (2) ICPm alone. Data are presented as medians (interquartile range) and odds ratios (ORs) (95% confidence interval).

Nonoperative management of acute calculous cholecystitis (ACC) in the frail geriatric population is underexplored. The aim of our study was to examine long-term outcomes of frail geriatric patients with ACC treated with cholecystectomy compared with initial nonoperative management.
We conducted a 2017 analysis of the Nationwide Readmissions Database and included frail geriatric (≥65 years) patients with ACC. Frailty was assessed using the five-factor modified frailty index. Patients were stratified into those undergoing cholecystectomy at index admission (operative management [OP]) versus those managed with nonoperative intervention (nonoperative management [NOP]). The NOP group was further subdivided into those who received antibiotics only and those who received percutaneous drainage. Primary outcomes were procedure-related complications in the OP group and 6-month failure of NOP (readmission with cholecystitis). Secondary outcomes were mortality and overall hospital length of stay.
A total of 53,412 geriatric patients with ACC were identified, 51.
