OBJECTIVE: To determine if a self-report measure of S4-5 motor and sensory function in patients with chronic SCI accurately predicts sacral examination results. DESIGN: Prospective, single-blinded self-report survey compared with sacral exam. SETTING: Outpatient SCI clinic. PARTICIPANTS: 116 patients aged 18+ with chronic SCI > 6 months who have undergone sacral exam. INTERVENTIONS: The survey included demographic/clinical and sacral function information such as light tough (LT), pinprick sensation (PP), deep anal pressure (DAP) and voluntary anal contraction (VAC). Survey results and sacral exam were compared and stratified by the patient’s American Spinal Cord Injury Association Impairment Scale (AIS) category. OUTCOME MEASURES: Sacral self-report survey, AIS examination. RESULTS: Mean age was 41.3 +/- 14.4 years with majority male (69%) and Caucasian (71.6%). Overall, Positive Predictive Value (PPV) ranged between 48% (VAC) to 73% (DAP) and Negative Predictive Value (NPV) between 92% (VAC) to 100% (LT). AIS-A had NPV of 100% across all categories, and AIS-D had PPV of 100% across all categories. CONCLUSION: Patient report of sacral sparing can predict negative sensation in patients with AIS-A and predict positive sensation in persons with AIS-D. Overall, the self-report of sacral sparing of motor and sensory function is not predictive enough to rely on for accurate classification.

OBJECTIVES: To examine adherence with and effect of an evidence-based healthy lifestyle intervention modified for individuals with traumatic brain injury (TBI). DESIGN: Pre-/postintervention without control. SETTING: Community. PARTICIPANTS: Eighteen individuals with TBI: primarily male (61%), white (67%), with private insurance (50%). Mean age was 45.6 +/- 12.3 years, weight 210 +/- 42.6 lb, and body mass index 31.8 +/- 4.6 (obese category) at baseline. INTERVENTIONS: The primary goal of the Diabetes Prevention Program Group Lifestyle Balance program is 5% to 7% weight loss through increased physical activity and improved dietary behaviors. MAIN OUTCOME MEASURE(S): Adherence (ie, session attendance and self-monitoring of dietary behaviors), physiologic changes (ie, weight loss, blood pressure; waist and arm circumference; and lipid profile), and quality of life (ie, self-reported health, quality of life, and step count). RESULTS: Average participant attendance (85% over 12 months) and self-monitoring (90% over 6 months) were high. Significant decreases were observed in diastolic blood pressure and waist and arm circumference from baseline through 12 months and from baseline to 3 months only for weight and total cholesterol. No significant changes were observed in self-reported health, quality of life, or step count. CONCLUSIONS: Participants demonstrated high adherence with the program, suggesting that individuals with TBI are able to successfully engage in the program and achieve significant weight loss and changes in key physiologic outcomes.

OBJECTIVE: There are no large studies evaluating pulmonary haemorrhage (PH) in premature infants. We sought to quantify the clinical characteristics, morbidities and mortality associated with early PH. DESIGN: Data were abstracted from the Pediatrix Clinical Data Warehouse, a large de-identified data set. For incidence calculations, we included infants from 340 Pediatrix United States Neonatal Intensive Care Units from 2005 to 2014 without congenital anomalies. Infants <28 weeks' gestation with PH within 7 days of birth were then matched with two controls for birth weight, gestational age, gender, antenatal steroid exposure, day of life 0 or 1 intubation and multiple gestation. RESULTS: From 596 411 total infants, we identified 2799 with a diagnosis of PH. Peak incidence was 86.9 cases per 1000 admissions for neonates born at 24 weeks' gestation. We then identified 1476 infants <28 weeks' gestation with an early PH diagnosis at

OBJECTIVE: Describe (1) weight loss history, (2) perceptions about lifestyle changes, and (3) physical activity among a sample of individuals with traumatic brain injury prior to a 12-month lifestyle change program. SETTING: Community-based. PARTICIPANTS: Individuals enrolled in a lifestyle change program, 6 months or more post-traumatic brain injury, body mass index of 25 or greater, 18 to 64 years of age, with physician’s clearance to participate. DESIGN: Convenience sample. MAIN MEASURES: Self-report data were collected before beginning the lifestyle change program including descriptive, weight loss history and physical activity behavior using the Modifiable Activity Questionnaire. RESULTS: The final sample included 22 participants (M age = 46 years) injured a median of 8 years ago. Mean weight was 208.5 lb (SD = 40.2), with average body mass index of 31.84 (SD = 4.4). Since injury, 72.7% reported prior weight loss attempts, with 50% gaining 10 lb or more. All participants indicated high motivation for lifestyle changes. Perceived benefits included feeling better, improving overall health, and increased energy. Barriers included physical health complications. Types of physical activity completed included walking (68%, 180 min/mo) and swimming (32%, 79 min/mo). CONCLUSION: Results indicate that many individuals gained weight since injury and attempted weight loss, demonstrating a need for evidence-based lifestyle interventions. Future research is needed to determine whether individuals with traumatic brain injury are able to achieve and maintain weigh loss through intervention.

OBJECTIVE: Posttraumatic growth (PTG) describes positive change resulting from challenging life events. The current study examined factors associated with PTG in traumatically injured patients 1 year postinjury. METHOD: Participants (N = 221) in this prospective cohort study included adults admitted to a Level I trauma center. Over half the participants (60%) were male, with a mean age of 47. Participants completed baseline measures during hospitalization. PTG was assessed at 12-month follow-up. RESULTS: Greater PTG was associated with minority race/ethnicity, lower income, automotive collision, and premorbid psychological disorder other than depression or posttraumatic stress (PTS). These variables are also known to predict PTS in trauma patients. Analysis confirmed that greater PTS at follow-up was associated with more growth. CONCLUSION: Participants with the most growth also experienced the most distress. This finding demonstrates the importance of implementing psychological screening and intervention for trauma patients in the acute care setting to reduce PTS and facilitate growth.
