“…Boni and Denaro [7] discussed this issue in 1982 but considered degeneration adjacent to a fusion at the cervical spine as clinically irrelevant. This was later confirmed by Hilibrand et al [40], who highlighted the role of natural history of the degenerated disc adjacent to the fused vertebrae, and by other authors [27], who outlined the role of postoperative cervical sagittal alignment in determining the accelerated degeneration of the disc adjacent to a fusion.…”

“…5,9 However, ACDF inherently decreases motion between the 2 fused vertebral segments, which has led to the advent of nonfusion techniques such as cervical disc replacement (CDR). 7,15 In the past decade, multiple studies have examined long-term outcomes 2, 5, and 7 years after ACDF and after CDR.…”

OBJECTIVE The goal of this study was to compare 30-day readmission and reoperation rates after single-level anterior cervical discectomy and fusion (ACDF) versus those after cervical disc replacement (CDR). METHODS The authors used the 2013–2014 American College of Surgeons National Surgical Quality Improvement Program database. Included were adult patients who underwent first-time single-level ACDF or CDR for cervical spondylosis or disc herniation. Primary outcome measures were readmission and/or reoperation within 30 days of the original surgery. Logistic regression analysis was used to assess the independent effect of the procedure (ACDF or CDR) on outcome, and results are presented as odds ratios with 95% confidence intervals. RESULTS A total of 6077 patients met the inclusion criteria; 5590 (92.0%) patients underwent single-level ACDF, and 487 (8.0%) patients underwent CDR. The readmission rates were 2.6% for ACDF and 0.4% for CDR (p = 0.003). When stratified according to age groups, only patients between the ages of 41 and 60 years who underwent ACDF had a significantly higher readmission rate than those who underwent CDR (2.5% vs 0.7%, respectively; p = 0.028). After controlling for patient age, sex, body mass index, smoking status, history of chronic obstructive pulmonary disease (COPD), diabetes, hypertension, steroid use, and American Society of Anesthesiologists (ASA) class, patients who underwent CDR were significantly less likely to undergo readmission within 30 days than patients who underwent ACDF (OR 0.23 [95% CI 0.06–0.95]; p = 0.041). Patients with a history of COPD (OR 1.97 [95% CI 1.08–3.57]; p = 0.026) or hypertension (OR 1.62 [95% CI 1.10–2.38]; p = 0.013) and those at ASA Class IV (OR 14.6 [95% CI 1.69–125.75]; p = 0.015) were significantly more likely to require readmission within 30 days. The reoperation rates were 1.2% for ACDF and 0.4% for CDR (p = 0.086), and multivariate analysis revealed that CDR was not associated with lower odds of reoperation (OR 0.60 [95% CI 0.14–2.55]; p = 0.492). However, increasing age was associated with a higher risk (OR 1.02 [95% CI 1.00–1.05]; p = 0.031) of reoperation; a 2% increase in risk per year of age was found. CONCLUSIONS Patients who underwent single-level ACDF had a higher readmission rate than those who underwent single-level CDR in this study. When stratified according to age, this effect was seen only in the 41- to 60-year age group. No significant difference in the 30-day single-level ACDF and single-level CDR reoperation rates was found. Although patients in the ACDF group were older and sicker, other unmeasured covariates might have accounted for the increased rate of readmission in this group, and further investigation is encouraged.

Background: To study overall and province-specific trends of bladder cancer incidence in Iran during [2004][2005][2006][2007][2008] and to evaluate the association between bladder cancer incidence and some factors.Methods: Data on 17792 bladder cancer patients and risk factors available at province level were used in Bayesian ecological setting. First, the overall and province-specific trends of risk were estimated. Then the effects of cigarette smoking, being overweight, fruits and vegetables consumption, and low levels of physical activity on trend were examined. The province-specific effects of significant factors were also assessed. The data were analyzed using R-INLA package. Results:The risk of developing bladder cancer was decreasing in Iran, 2004 -2008 (RR = 0.95). Guilan and Semnan had the highest 5-year incidence (RR > 1.5). However, the risk increase compared to country Risk was the highest in East Azerbaijan and Tehran (DT > 0.1). Also direct and reverse association between smoking and fruit consumption and bladder cancer risk were established. Guilan, Semnan, Sistan and Baluchestan, and Ilam were the provinces affected the most by these factors. Conclusions:This study confirms previous findings and provides further evidence on protective effects of fruit consumption in bladder cancer. The results would be of value for governors to prioritize the province-specific demands on research, education, and improvements with respect to the identified risk factors.
