However, during the post-typhoon, the stratification of nutrients is less significant and their distribution more homogenous in the whole water column of the nearshore area. In the upper water, the nutrient concentration increased and the temperature decreased significantly. These results suggest that the enhanced vertical mixing induced by the typhoon was the dominant process in changing the nutrient distribution pattern in the coastal NSCS.Unusually large outbreaks of mumps across the United States in 2016 and 2017 raised questions about the extent of mumps circulation and the relationship between these and prior outbreaks. We paired epidemiological data from public health investigations with analysis of mumps virus whole genome sequences from 201 infected individuals, focusing on Massachusetts university communities. Our analysis suggests continuous, undetected circulation of mumps locally and nationally, including multiple independent introductions into Massachusetts and into individual communities. Despite the presence of these multiple mumps virus lineages, the genomic data show that one lineage has dominated in the US since at least 2006. Widespread transmission was surprising given high vaccination rates, but we found no genetic evidence that variants arising during this outbreak contributed to vaccine escape. Viral genomic data allowed us to reconstruct mumps transmission links not evident from epidemiological data or standard single-gene surveillance efforts and also revealed connections between apparently unrelated mumps outbreaks.BACKGROUND Osteoarthritis secondary to developmental dysplasia of the hip (DDH) is one of the major causes of hip pain and disability. The aim of the study was to compare the effectiveness of prolotherapy (PrT) injections versus exercise protocol for the treatment of DDH. MATERIAL AND METHODS There were 46 hips of 41 patients who had osteoarthritis secondary to DDH included in this study. Patients were divided into 2 groups treated with PrT (PrT group; n=20) and exercise (control group; n=21). Clinical outcomes were evaluated with visual analog scale for pain (VAS) and Harris hip score (HHS) at baseline, 3 weeks, 3 months, 6 months, and a minimum of 1-year follow-up. In PrT group clinical results were also compared in Crowe type I-IV hips. RESULTS Between group analysis revealed no significant between group differences at baseline. Dextrose injection recipients out performed exercise controls for VAS pain change score at 6 months (-4.6±2.6 versus -2.8±2.5; P=0.016), and 12 months (-4.5±2.4 versus -2.9±2.5; P=0.017) and for HHS at 6 months (24.2±14.0 versus 14.8±12.4; P=0.007) and 12 months (24.3±13.4 versus 16.5±11.3; P=0.018). CONCLUSIONS To our best knowledge, this study is the first regarding the effects of an injection method in the treatment of osteoarthritis secondary to DDH. According to our study, PrT is superior to exercises. PrT could provide significant improvement for clinical outcomes in DDH and might delay surgery.STUDY DESIGN Retrospective cohort study of prospectively collected data. OBJECTIVE Assess correlation between preoperative platelet counts and postoperative adverse events after elective posterior lumbar surgery procedures. SUMMARY OF BACKGROUND DATA Preoperative low platelet counts have been correlated with adverse outcomes after posterior lumbar surgery. Nonetheless, the effect of varying platelet counts has not been studied in detail for a large patient population, especially on the high end of the platelet spectrum. METHODS Patients who underwent elective posterior lumbar surgery were identified in the 2011 to 2016 National Surgical Quality Improvement Program database. Preoperative platelet counts were considered relative to 30-day perioperative adverse outcomes. Patients were classified into platelet categories based on determining upper and lower bounds on when the adverse outcomes crossed a relative risk of 1.5. Univariate and multivariate analyses compared 30-day postoperative complications, readmissh, as well as low, preoperative platelet counts. LEVEL OF EVIDENCE 3.STUDY DESIGN A cross-sectional study. OBJECTIVE The aim of this study is to describe the profile of patients with acute low back pain (LBP) who sought emergency departments (EDs) in Brazilian public hospitals. We also described the profile of these patients according to the STarT Back Screening Tool (SBST). SUMMARY OF BACKGROUND DATA LBP is the most common musculoskeletal condition worldwide and is one of the main complaints in EDs. There is a lack of evidence describing the profile of these patients from low- to middle-income countries. METHODS This is a cross-sectional study involving patients with a new episode of nonspecific acute LBP that was conducted between August 2014 and August 2016. Variables related to clinical, psychological, sociodemographic and work status characteristics were investigated through structured, in-person oral questionnaire. RESULTS A total of 600 patients were included in the study. The majority of the patients were women (58%), with a median of eight points on pain intensity (measured on an 11-point scale) and 17 points on disability (measured on a 24-item questionnaire). With regards to the SBST evaluation, 295 (49.2%) patients were classified as being at high risk of developing an unfavorable prognosis with a median pain intensity of nine points on pain intensity, 20 points on disability, and seven points on depression (measured on an 11-point scale). Despite this, the majority of the patients (74%) continued working normally without interference from LBP. CONCLUSION Identifying the profile of patients seeking care in EDs can help to define effective management for LBP in low- and middle-income countries. Patients with nonspecific acute LBP who seek EDs in Brazil present high levels of pain intensity and disability. Most patients were classified as having a high risk of developing an unfavorable prognosis. LEVEL OF EVIDENCE 2.STUDY DESIGN This was a retrospective study using national administrative data from the MarketScan database. OBJECTIVE To investigate the complication rates, quality outcomes, and costs in a nationwide cohort of patients with movement disorders (MD) who undergo spinal deformity surgery. SUMMARY OF BACKGROUND DATA Patients with MD often present with spinal deformities, but their tolerance for surgical intervention is unknown. METHODS The MarketScan administrative claims database was queried to identify adult patients with MD who underwent spinal deformity surgery. A propensity-score match was conducted to create two uniform cohorts and mitigate interpopulation confounders. Perioperative complication rates, 90-day postoperative outcomes, and total costs were compared between patients with MD and controls. RESULTS A total of 316 patients with MD (1.7%) were identified from the 18,970 undergoing spinal deformity surgery. The complication rate for MD patients was 44.6% and for the controls 35.6% (P = 0.009). The th patients without these disorders. LEVEL OF EVIDENCE 3.STUDY DESIGN Retrospective database review. OBJECTIVE Compare 1-year episode of care costs between single-level decompression and decompression plus fusion for lumbar stenosis. SUMMARY OF BACKGROUND DATA Lumbar stenosis is the most common indication for surgery in patients over 65. Medicare direct hospital costs for lumbar surgery reached $1.65 billion in 2007. Despite stenosis being a common indication for surgery, there is debate as to the preferred surgical treatment. Cost-minimization analysis is a framework that identifies potential cost savings between treatment options that have similar outcomes. A922500 We performed a cost-minimization analysis of decompression versus decompression with fusion for lumbar stenosis from the payer perspective. METHODS An administrative claims database of privately insured patients (Humana) identified patients who underwent decompression (n = 5349) or decompression with fusion (n = 8540) for lumbar stenosis with and without spondylolisthesis and compared overall costs. All patienrted outcomes, and preferences should also be recognized as drivers of healthcare decisions. LEVEL OF EVIDENCE 3.STUDY DESIGN A retrospective study. OBJECTIVE The aim of this study was to determine whether the last substantially touching vertebra (LSTV) can be selected as the optimal lowest instrumented vertebra (LIV) for Lenke 2A adolescent idiopathic scoliosis (AIS) with different lumbar modifiers (2A-R and 2A-L) and to investigate its relationship with the distal adding-on. SUMMARY OF BACKGROUND DATA Previous studies have documented good outcomes in Lenke 1A curve when LSTV was selected as LIV. METHODS A total of 101 female patients were included with a minimum of 2-year follow-up after selective posterior surgery. Patients were classified on the basis of the direction of L4 tilt 2A-L and 2A-R. Patients with LSTV-1, LSTV, or LSTV+1 selected as LIV were assigned to three groups. Factors associated with adding-on were analyzed through comparison among the three groups. RESULTS The level of LSTV was more distal in the 2A-R group than that in the 2A-L group (P = 0.011). Distal adding-on was observed in 24 patients (23.8%on.

Postoperative venous thromboembolism has been studied previously, but no large study has compared the risks during different stages of treatment. OBJECTIVE This study aimed to quantify and compare the risks of venous thromboembolism before surgery, after surgery, during adjuvant chemotherapy, and up to 365 days after surgery among patients with resected colon cancer. DESIGN This is a population-based retrospective cohort study. SETTING This study was conducted in a single-payer, universal health care setting (Ontario) between 2002 and 2008. PATIENTS A total of 6806 patients with stage I to III colon cancer treated with surgical resection were included. INTERVENTIONS Phases of treatment were evaluated, including preoperative, in-hospital, postoperative, during adjuvant chemotherapy, and 365 days postoperatively. MAIN OUTCOME MEASURES Venous thromboembolism, as defined using diagnostic codes from administrative data sources, was the primary outcome measured.
