Project description:PTSD - Posttraumatic stress disorder. 33 samples taken from PMBCs of survivors of psychological trauma, in two time points: in ER, few hours after the truma, and four months later. Some of the patients devepled chronic PTSD (17 samples) and others recovered and set to be the Control group (16 samples). This is the raw data consists of 12,600 probes from U95A chip. Samples are labeled with 3 tags: P/C for PTSD or Control, ER/M4 - for time point of sample, D/ND for Decrement or Non-decrement symptoms over time. (e.g. sample 23C-M4-D was taken 4 months after trauma from patient 23 which belongs to the control group and showed decrease in symptoms) . Samples include the expression value, the GeneBank accession number and Affymetrix indication of valid calls. Keywords: other

Project description:In this article we report data collected to evaluate the pathomechanistic effect of acute anaerobic metabolism in the polytraumatized patient and its subsequent effect on fracture nonunion; see "Base Deficit ≥6 within 24 Hours of Injury is a Risk Factor for Fracture Nonunion in the Polytraumatized Patient" (Sardesai et al., 2021) [1]. Data was collected on patients age ≥16 with an Injury Severity Score (ISS) >16 that presented between 2013-2018 who sustained a fracture of the tibia or femur distal to the femoral neck. Patients presenting to our institution greater than 24 hours post-injury and those with less than three months follow-up were excluded. Medical charts were reviewed to collect patient demographic information and known nonunion risk-factors, including smoking, alcohol use, and diabetes. In addition, detailed injury characteristics to quantify injury magnitude including ISS, Glasgow Coma Scale (GCS) at admission, and ICU length of stay were recorded. ISS values were obtained from our institutional trauma database where they are entered by individuals trained in ISS calculations. Associated fracture-related features including fracture location, soft-tissue injury (open vs. closed fracture), vascular injury, and compartment syndrome were recorded. Finally, vital signs, base deficit (BD), and blood transfusions over 24 hours from admission were recorded. We routinely measure BD and less consistently measure serum lactate in trauma patients at the time of presentation or during resuscitation. BD values are automatically produced by our laboratory with any arterial blood gas order, and we recorded BD values from the medical record. Clinical notes and radiographs were reviewed to confirm fracture union versus nonunion and assess for deep infection at the fracture site. Patients were categorized as having a deep infection if they were treated operatively for the infection prior to fracture healing or classification as a nonunion. Nonunion was defined by failure of progressive healing on sequential radiographs and/or surgical treatment for nonunion repair at least six months post-injury.
Project description:Neutron spin-echo spectrometers with a position-sensitive detector and operating with extended time-of-flight-tagged wavelength frames are able to collect a comprehensive set of data covering a large range of wavevector and Fourier time space with only a few instrumental settings in a quasi-continuous way. Extracting all the information contained in the raw data and mapping them to a suitable physical space in the most efficient way is a challenge. This article reports algorithms employed in dedicated software, DrSpine (data reduction for spin echo), that achieves this goal and yields reliable representations of the intermediate scattering function S(Q,?t) independent of the selected 'binning'.
