The PTSD Checklist for DSM-5 (PCL-5) is a valid, efficient measure of symptom severity, but its completion is time consuming. Subsequently, abbreviated four- and eight-item versions were developed using the Mini-International Neuropsychiatric Interview-7 PTSD module and validated in Veteran samples. This study aimed to validate these abbreviated versions using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), the gold standard for PTSD diagnosis, in a traumatically injured civilian population. Participants were 251 traumatically injured adults (Mage = 42.52 years; 69.3% male; 50.2% Caucasian) recruited from a Level 1 trauma center inpatient unit; 32.3% and 17.9% of participants experienced a motor vehicle crash or gunshot wound, respectively. The CAPS-5 and PCL-5 were administered approximately 6.5 months postinjury. We examined whether compared to the full PCL-5, the abbreviated versions would adequately differentiate between participants with and without a CAPS-5 PTSD diagnosis. The abbreviated versions were highly correlated with the total scale and showed good-to-excellent internal consistency. The diagnostic utility of the abbreviated measures was comparable to that of the total scale regarding sensitivity, suggesting they may be useful as abbreviated screening tools; however, the total scale functioned better regarding specificity. The abbreviated versions of the PCL-5 may be useful screening instruments in the long-term care of traumatic injury survivors and may be more likely to be implemented across routine clinical and research contexts. © 2020 International Society for Traumatic Stress Studies.OBJECTIVE To report recovery of ambulation of dogs treated with extended thoracolumbar durotomy for severe spinal cord injury caused by intervertebral disc herniation. STUDY DESIGN Descriptive cohort. ANIMALS Twenty-six consecutive paraplegic dogs presented with loss of deep pain sensation after acute thoracolumbar intervertebral disc herniation. METHODS Each dog underwent routine diagnostic assessment and surgery for removal of extradural herniated intervertebral disc, followed by a four-vertebral body length durotomy centered on the herniated disc. Each dog was followed up until it was able to walk 10 steps without assistance or until 6 months after surgery. RESULTS Sixteen of 26 dogs recovered to walk unaided (all but one also recovered fecal and urinary continence), and six dogs did not; four dogs were lost to follow-up. One dog was euthanized because of signs consistent with progressive myelomalacia. There was no evidence of detrimental effects of durotomy within the period of study. Using Bayesian analysis, we found a point estimate of successful outcome of 71% with 95% credible interval from 52% to 87%. CONCLUSION Extended durotomy seemed to improve the outcome of dogs in our case series without increase in morbidity. CLINICAL SIGNIFICANCE Extended durotomy appears safe and may improve the outcome of dogs with severe thoracolumbar mixed contusion and compressive injuries associated with acute intervertebral disc extrusion. © 2020 The American College of Veterinary Surgeons.in English, Spanish ANTECEDENTES El objetivo de este estudio fue comparar los resultados perioperatorios entre la colectomía urgente y la colocación de una endoprótesis (stent) metálica autoexpandible seguida de colectomía en pacientes con obstrucción maligna del colon derecho. La obstrucción maligna del colon derecho es menos frecuente que la del colon izquierdo. Se ha demostrado que la colocación de una endoprótesis en la obstrucción maligna del colon izquierdo reduce las complicaciones postoperatorias. Sin embargo, el impacto de la colocación de una endoprótesis en la obstrucción maligna del colon derecho no está definido. MÉTODOS Los pacientes con obstrucción o estenosis maligna del colon derecho sometidos a colectomía desde abril de 2012 hasta marzo de 2017 se analizaron a partir de una base de datos nacional. Se realizó un análisis mediante emparejamiento por puntaje de propensión para comparar la mortalidad, la morbilidad, el porcentaje de pacientes en los que se realizó un estoma y la estancia postopede una endoprótesis (15 días versus 13 días, P less then  0,001) CONCLUSIÓN En pacientes con obstrucción maligna del colon derecho, la colocación de una endoprótesis seguida de colectomía puede proporcionar resultados perioperatorios más favorables en comparación con la colectomía urgente.We report the case of a patient in whom we used deep cerebral venous blood flow monitoring by transcranial Doppler ultrasonography to monitor the effect of anticoagulation therapy on cerebral venous sinus thrombosis. The blood flow velocity of deep cerebral veins increased in the early stage of cerebral venous sinus thrombosis, then gradually decreased to the normal level as the disease improved. Moreover, the recovery of the blood flow velocity of deep cerebral veins occurred earlier than the morphological recovery demonstrated by magnetic resonance venography. © 2020 Wiley Periodicals, Inc.Mitochondrial shape and function are known to be linked; therefore, there is a need to combine three-dimensional EM structural analysis with functional analysis. Cytochrome c oxidase labelling is one approach to examine mitochondrial function at the EM level. However, previous efforts to apply this method have had several issues including inconsistent results, disruption to mitochondrial ultrastructure, and a lack of optimisation for volume EM methods. We have used short fixation and microwave processing to address these issues. We show that our method gives consistent cytochrome c oxidase labelling and improves labelling penetration across tissue volume. We also quantify mitochondrial morphology metrics, including in volume EM, to show that ultrastructure is unaltered by the processing. This work represents a technical advance that allows the correlation of mitochondrial function and morphology with greater resolution and volume than has previously been feasible. LAY SUMMARY Transmission electron microscopy (TEM) is a high-resolution technique used for the study of cells and their components, such as mitochondria.
