Comprehensive mitogenome associated with Phthorimaea operculella (Lepidoptera: Gelechioidea: Gelechiidae).
ients appear to be at highest risk after severe blunt TBI, with significantly increased risks of morbidity and mortality.Objective Patients' expectations for pain relief are associated with patient-reported outcomes after treatment, although this has not been examined in patients with adult spinal deformity (ASD). The aim of this study was to identify associations between patients' preoperative expectations for pain relief after ASD surgery and patient-reported pain at the 2-year follow-up. Methods The authors analyzed surgically treated ASD patients at a single institution who completed a survey question about expectations for back pain relief. Five ordinal answer choices to "I expect my back pain to improve" were used to categorize patients as having low or high expectations. Back pain was measured using the 10-point numeric rating scale (NRS) and Scoliosis Research Society-22r (SRS-22r) patient survey. Preoperative and postoperative pain were compared using analysis of covariance. Results Of 140 ASD patients eligible for 2-year follow-up, 105 patients (77 women) had pre- and postoperative data on patient expectations, 85 of whom had high expectations. The mean patient age was 59 ± 12 years, and 46 patients (44%) had undergone previous spine surgery. The high-expectations and low-expectations groups had similar baseline demographic and clinical characteristics (p > 0.05), except for lower SRS-22r mental health scores in those with low expectations. After controlling for baseline characteristics and mental health, the mean postoperative NRS score was significantly better (lower) in the high-expectations group (3.5 ± 3.5) than in the low-expectations group (5.4 ± 3.7) (p = 0.049). The mean postoperative SRS-22r pain score was significantly better (higher) in the high-expectations group (3.3 ± 1.1) than in the low-expectations group (2.6 ± 0.94) (p = 0.019). Conclusions Despite similar baseline characteristics, patients with high preoperative expectations for back pain relief reported less pain 2 years after ASD surgery than patients with low preoperative expectations.Objective Degenerative cervical myelopathy (DCM) is the most common cause of spinal cord dysfunction in adults. Multilevel ventral compressive pathology is routinely managed through anterior decompression and reconstruction, but there remains uncertainty regarding the relative safety and efficacy of multiple discectomies, multiple corpectomies, or hybrid corpectomy-discectomy. To that end, using a large national administrative healthcare data set, the authors sought to compare the perioperative outcomes of anterior cervical discectomy and fusion (ACDF), anterior cervical corpectomy and fusion (ACCF), and hybrid corpectomy-discectomy for multilevel DCM. Methods Patients with a primary diagnosis of DCM who underwent an elective anterior cervical decompression and reconstruction operation over 3 cervical spinal segments were identified from the 2012-2017 National Surgical Quality Improvement Program database. Patients were separated into those undergoing 3-level discectomy, 2-level corpectomy, or a hybrid proced). In contrast, hybrid corpectomy-discectomy had comparable outcomes to 3-level ACDF but was associated with significantly shorter operative duration (aMD -16.9 minutes, p = 0.002). Conclusions The authors found multiple discectomies and hybrid corpectomy-discectomy to have a comparable safety profile in treating multilevel DCM. In contrast, multiple corpectomies were associated with a higher complication rate, longer hospital LOS, and lower likelihood of being discharged directly home from the hospital, and may therefore be a higher-risk operation.Objective Patients undergoing open cranial vault remodeling for craniosynostosis frequently experience substantial blood loss requiring blood transfusion. Multiple reports in the literature have evaluated the impact of individual blood conservation techniques on blood transfusion rates during craniosynostosis surgery. see more The authors engaged a multidisciplinary team and assessed the impact of input from multiple stakeholders on the evolution of a comprehensive quality improvement protocol aimed at reducing or eliminating blood transfusion in patients undergoing open surgery for craniosynostosis. Methods Over a 4-year period from 2012 to 2016, 39 nonsyndromic patients were operated on by a single craniofacial plastic surgeon. Initially, no clear blood conservation protocol existed, and specific interventions were individually driven. In 2014, a new pediatric neurosurgeon joined the craniofacial team, and additional stakeholders in anesthesiology, transfusion medicine, critical care, and hematology were brought togobin/hematocrit (11.1 g/dl/31.8% to 14.7 g/dl/45.6%, p less then 0.05). The group of patients receiving ACA had lower intraoperative EBL than those not receiving ACA, and trends in the final-protocol cohort, which had received both preoperative EPO and intraoperative ACA, demonstrated decreasing transfusion volumes, though the decrease did not reach statistical significance. Conclusions Patients undergoing open calvarial vault remodeling procedures benefit from the input of a multidisciplinary stakeholder group in blood conservation protocols. Further research into comprehensive protocols for blood conservation may benefit from input from the full surgical team (plastic surgery, neurosurgery, anesthesiology) as well as additional pediatric subspecialty stakeholders including transfusion medicine, critical care, and hematology.Objective The goal of this study was to determine the functional efficacy of acellular processed nerve allograft (ALG) as compared to sural nerve autograft (AUG) harvested at time of surgery for children with obstetrical brachial plexus injury (OBPI). Methods A retrospective review of records was performed in patients who underwent surgical repair of OBPI between 2009 and 2015 at Phoenix Children's Hospital. Patients were grouped based on the type of nerve graft used (AUG using the patient's own sural nerve or decellularized processed cadaveric nerve ALG) and compared in terms of motor strength, British Medical Research Council score, functionality (Mallet scale score), surgical time, rate of complications, and need for further intervention. Results A total of 52 records were identified meeting study criteria. Sural nerve AUG was used in 22 cases and ALG in 30 cases. Changes from pre- to postsurgical assessment of motor strength were significant for all muscle groups measured except for elbow extension for both groups.
