Lumbar interbody fusions are being performed with increased frequency in the last decade. Anterior and posterior interbody techniques have demonstrated relatively similar success rates. Nonetheless, despite increased attention to cost-effective care delivery, approach-related differences in procedural cost and predictors for these differences remain poorly defined. The purpose of this investigation was to characterize the variability in cost for anterior versus posterior-based lumbar interbody fusions and to identify key predictors of procedural cost.
We evaluated the records of all patients who underwent a primary anterior (ALIF) or posterior/transforaminal (PLIF/TLIF) lumbar interbody fusion with concomitant posterior fusion from 2016 to 2020 at four hospitals in a major metropolitan area. We reviewed the records of all included patients and abstracted demographics, insurance status, approach, operative time, diagnosis, surgeon, institution, open versus minimally invasive technique, and components of pr findings should be considered in an ecosystem increasingly attentive to cost effective care delivery. This work has also provided specific procedural variables for surgeons and systems to target when optimizing procedural costs.
Our findings demonstrate that anterior interbody techniques are, on average, 173% (anterior, $16316 [SE 556] vs. posterior, $9415 [SE 345]; p less then 0.001) more expensive than posterior-based procedures. Given the relative equipoise of these different approaches for many clinical applications, these findings should be considered in an ecosystem increasingly attentive to cost effective care delivery.

Deep brain stimulation (DBS) is indisputable in improving motor symptoms of Parkinson's Disease (PD) and X-Linked Dystonia Parkinsonism (XDP)(4,9,22,23,26). However, a discrepancy between this improvement and the perceived quality of life (QoL) has been observed. This study aims to investigate changes and correlation between quality of life, motor symptoms and medication dosing.
This prospective observational study enrolled 13 patients (6 PD, 7 XDP) who underwent DBS from 2017 to 2018. Quality of life changes were determined by Parkinson's Disease - 39 (PDQ-39 English and Filipino versions) at baseline, 6 months and 12 month after DBS. Motor symptoms and medication dosing were also evaluated within the same period and correlated with QoL changes.
There is a significant reduction of PDQ-39 mean scores[F(1.06,11.64)=18.235; p=0.001; ηp2=0.624] between baseline and 6 months among XDP patients (p=0.018) and baseline and 12 months among PD patients (p=0.027) and XDP patients (p<0.001). Specific domains with significant improvement were stigma, cognition, mobility, ADLs, communication and bodily discomfort. Correlating these with changes in motor symptoms, only mobility for PD and ADLs for XDP were positively related.
This study has shown the positive impact of DBS in improving QoL among PD and XDP patients over a 12-month period.

To investigate the clinical and genetic features of hereditary spastic paraplegia (HSP) type 3A (SPG3A) in Taiwan.
Mutational analysis of the ATL1 gene was performed for 274 unrelated Taiwanese HSP patients. Rolipram in vivo The diagnosis of SPG3A was ascertained by the presence of a heterozygous pathogenic mutation in ATL1. The SPG3A patients received clinical, electrophysiological, and neuroimaging evaluations. Disease severity was assessed by using Spastic Paraplegia Rating Scale (SPRS) and disability score. Nineteen single nucleotide polymorphism (SNP) markers flanking ATL1 were genotyped for haplotype analysis of ATL1 p.R416C mutation.
Eighteen SPG3A patients from 11 families were identified. They typically presented a pure form HSP phenotype with disease onset ranging from age 1-68 years. Five heterozygous ATL1 mutations were identified, including p.R239C, p.V253I, p.Y336H, p.P342R and p.R416C. ATL1 p.R416C was the most common mutation and presented in five SPG3A pedigrees. Haplotype analyses demonstrated a shared haplotype in the 12 individuals carrying a p.R416C allele.
SPG3A accounts for 4% (11 out of 274) of HSP in the Taiwanese cohort. Patents with the ATL1 p.R416C mutation in Taiwan may descend from a common ancestor. This study defines the clinical and genetic features of SPG3A in Taiwan and provides useful information for the diagnosis and management, especially in patients of Han Chinese descent.

The response of freezing of gait (FOG) to deep brain stimulation of the subthalamic nucleus (STN-DBS) is controversial and depends on many poorly controlled factors. On the other hand, a clinical predictor for the individual patient is needed to counsel the patient regarding this symptom.
A cohort of 124 patients undergoing STN-DBS was evaluated based on the video-documented Levodopa test at baseline in the OFF- and ON-drug condition and postoperatively in the best condition (ON-drug/ON-stim) and the worst condition (OFF-drug/ON-stim). We compared the freezing item of the Unified Parkinson's disease rating scale (#14), the UPDRS III total score, and FOG severity rated during four provoking situations with regard to its predictive value.
We found 'FOG during the turning task' to be the best predictor with an ROC-value of 0.857 compared to 0.603 for the UPDRS Item 14 and 0.583 for the total UPDRS III. An improvement of 1 or 2 grades of the turning item during the preoperative levodopa test predicts an improvement during the worst condition postoperatively of 1 grade or more with an 80% probability.
This FOG prediction test is simple and clinically useful. The test needs to be studied in a prospective study.
