Introduction
We previously found racial differences in biochemical recurrence (BCR) after radical prostatectomy (RP) persisted after adjusting for socioeconomic status (SES) while SES did not predict BCR. The impact on long-term prostate cancer (PC) outcomes is unclear. We hypothesized higher SES would associate with better long-term outcomes regardless of race.Methods
Among 4,787 black and white men undergoing RP from 1988 to 2015 in the SEARCH Database, poverty (primary SES measure) was estimated by linking home ZIP-code to census data. Cox models were used to test the association between SES adjusting for demographic, clinicopathological features, and race with BCR, castration-resistant PC (CRPC), metastases, PC-specific mortality (PCSM), and all-cause mortality. Interactions between race and SES were tested.Results
Median follow-up was 98 months (Interquartile range: 54–150 months). There were no interactions between race and SES for BCR. Black men had 10%- to 11% increased BCR risk (P < 0.06) while SES was unrelated to BCR. There were interactions between SES and race for CRPC (P?=?0.002), metastasis (P?=?0.014), and PCSM (P = 0.004). Lower SES was associated with decreased CRPC (P?=?0.012), metastases (P?=?0.004), and PCSM (P?=?0.049) in black, but not white men (all P ≥ 0.22). Higher SES was associated with decreased all-cause mortality in both races.Conclusions
In an equal-access setting, lower SES associated with decreased CRPC, metastases, and PCSM in black but not white men. If confirmed, these findings suggest a complex relationship between race, SES, and PC with further research needed to understand why low SES in black men decreased the risk for poor PC outcomes after RP. 相似文献2.

BACKGROUND CONTEXT
Spinal epidural lipomatosis (SEL) is a condition in which excess lumbar epidural fat (EF) deposition often leads to compression of the cauda equina or nerve root. Although SEL is often observed in obese adults, no systematic research investigating the potential association between SEL and metabolic syndrome has been conducted.PURPOSE
To elucidate potential association between SEL and metabolic syndrome.STUDY DESIGN
An observational study used data of a medical checkup.PATIENT SAMPLE
We retrospectively reviewed data from consecutive subjects undergoing medical checkups. A total of 324 subjects (174 men and 150 women) were enrolled in this study.OUTCOME MEASURES
The correlation of EF accumulation with demographic data and metabolic-related factors was evaluated.METHODS
The degree of EF accumulation was evaluated based on the axial views of lumbar magnetic resonance imaging. Visceral and subcutaneous fat areas were measured at the navel level using abdominal computed tomography. Metabolic syndrome was diagnosed according to the criteria of the Japanese Society of Internal Medicine. The correlation of SEL with metabolic syndrome and metabolic-related conditions was statistically evaluated.RESULTS
The degree of EF accumulation demonstrated a significant correlation to body mass index, abdominal circumference, and visceral fat area. However, age, body fat percentage, and subcutaneous fat area showed no correlation with the degree of EF accumulation. Logistic regression analysis revealed that metabolic syndrome (odds ratio [OR]=3.8, 95% confidence interval [CI]=1.5–9.6) was significantly associated with SEL. Among the diagnostic criteria for metabolic syndrome, visceral fat area ≥100 cm2 (OR=4.8, 95% CI=1.5–15.3) and hypertension (OR=3.5, 95% CI=1.1–11.8) were observed to be independently associated with SEL.CONCLUSION
This is the first study to demonstrate that metabolic syndrome is associated with SEL in a relatively large, unbiased population. Our data suggest that metabolic-related conditions are potentially related to EF deposition and that SEL could be a previously unrecognized manifestation of metabolic syndrome. 相似文献3.

Background
The treatment approach to node-positive gallbladder cancer has unresolved issues with regard to the management of patients with a positive superior retro-pancreatic (level 13a) node, which is the highest level of spread. The American Joint Committee on Cancer remains unclear on the status of the 13a node.Methods
This retrospective study consisted of 165 patients with node-positive gallbladder cancer without distant metastasis. Patients were reclassified according to the American Joint Committee on Cancer eighth edition classification. The survival of patients with positive level 13a node was compared with that of patients with N1 disease (T stage-wise) and those with para-aortic nodal disease. A multivariate analysis was performed for factors affecting survival.Results
The 5-year survival of patients with positive level 13a with 1–3 nodes was similar to those with N1 disease (40.2% and 32.9%, respectively) and was better than those with more distant nodal spread (P < .05). In univariate and multivariate analyses, intraoperative blood loss (hazard ratio [HR] 1.58), R1 resection (HR 1.87), and T4 disease (versus T2, HR 3.44) were poor prognosticators. Pancreaticoduodenectomy may be beneficial in T2 patients.Conclusion
A positive superior retro-pancreatic node does not worsen the prognosis in an otherwise N1 disease in T1/T2 gallbladder cancer. It behaves like a regional lymph node and should be treated as such. 相似文献4.

BACKGROUND CONTEXT
Pedicle screw loosening is common after spinal fusion and can be associated with pseudoarthrosis and pain. With suspicion of screw loosening on standard radiographs, CT is currently considered the advanced imaging modality of choice. MRI with new metal artifact reduction techniques holds potential to be sensitive in detection of screw loosening. The sensitivity and specificity of either of the imaging modalities are yet clear.PURPOSE
To evaluate the sensitivity and specificity of three different image modalities (standard radiographs, CT, and MRI) for detection of pedicle screw loosening.STUDY DESIGN/SETTING
Cross-sectional diagnostic study.PATIENT SAMPLE
Forty-one patients (159 pedicle screws) undergoing revision surgeries after lumbar spinal fusion between August 2014 and April 2017 with preoperative radiographs, CT, and MRI with spinal metal artifact reduction (STIR WARP and TSE high bandwidth sequences).OUTCOME MEASURES
Sensitivity and specificity in detection of screw loosening for each imaging modality.METHODS
Screw torque force was measured intraoperatively and compared with preoperative screw loosening signs such as peri-screw edema in MRI and peri-screw osteolysis in CT and radiographs. A torque force of less than 60 Ncm was used to define a screw as loosened.RESULTS
Sensitivity and specificity in detection of screw loosening was 43.9% and 92.1% for MRI, 64.8% and 96.7% for CT, and 54.2% and 83.5% for standard radiographs, respectively.CONCLUSIONS
Despite improvement of MRI with metal artifact reduction MRI technique, CT remains the modality of choice. Even so, CT fails to detect all loosened pedicle screws. 相似文献5.
BACKGROUND
The pattern of linear graph schematized by visual analogue scale (VAS) score displaying pain worsening between 2 days and 2 weeks after selective nerve root block (SNRB) is called rebound pain.PURPOSE
The purpose of this study was to determine if sodium hyaluronate and carboxymethyl cellulose solution (HA-CMC sol) injection could reduce the occurrence of rebound pain at 3 days to 2 weeks after SNRB in patients with radiculopathy compared with injection with corticosteroids and local anesthetics alone.STUDY DESIGN/SETTING
Double blinded randomized controlled clinical trial.PATIENT SAMPLE
A total of 44 patients (23 of 24 patients in the Guardix group and 21 of 24 patients in the control group) who finished the follow-up session were subjects of this study.OUTCOME MEASUREMENT
Patients were asked to write down their average VAS pain scores daily for 12 weeks. Functional outcomes were assessed by Oswestry Disability Index, Roland Morris Disability Questionnaire , and Short Form-36.METHOD
A cocktail of corticosteroids, 1% lidocaine, 0.5% Bupivacaine, and 1 mL of normal saline was used for the control group whereas a cocktail of corticosteroids, 1% lidocaine, 0.5% Bupivacaine, and 1 mL of HA-CMC solution was used for the G group. Study participants were randomized into one of two treatment regimens. They were followed up for 3 months.RESULTS
VAS score at 2 weeks after the procedure was 4.19±1.32 in the control group, which was significantly (p<.05) higher than that (2.43±1.24) in the G group. VAS score at 6 weeks after the procedure was 4.00±1.23 in the control group and 3.22±1.45 in the G group, showing no significant (p=.077) difference between the two groups. There were no significant differences in functional outcomes at 6 or 12 weeks after the procedure.CONCLUSIONS
Compared with conventional cocktail used for SNRB, addition of HA-CMC sol showed effective control of rebound pain at 3 days to 2 weeks after the procedure. 相似文献6.

BACKGROUND CONTEXT
Surgical treatment of cervical ossification of the posterior longitudinal ligament (OPLL) has a high risk of various complications. Anterior decompression with fusion (ADF) and laminoplasty (LAMP) are the most representative surgical procedures. However, few studies have compared the two procedures in terms of perioperative surgical complications.PURPOSE
To compare the perioperative complications post-ADF and LAMP for cervical OPLL using a large national inpatient database.STUDY DESIGN
A retrospective cohort study with propensity score matching analysis.PATIENT SAMPLE
Overall, 8,718 (ADF/LAMP:1,333/7,485) patients who underwent surgery for cervical OPLL from April 1, 2010 to March 31, 2016 in hospitals using the diagnosis procedure combination were analyzed.OUTCOME MEASURES
The occurrence of postoperative complications during hospitalization.METHODS
We compared the perioperative systemic and local complications, reoperation rates, and costs between ADF and LAMP using propensity score matching analysis.RESULTS
One-to-one matching resulted in 1,192 pairs of patients who underwent ADF and LAMP. The postoperative cardiovascular event rate was significantly higher (ADF/LAMP=1.9/0.8%, p=.013) in the ADF group. The incidence rates of dysphagia (similarly, 2.4/0.2%, p<.001), pneumonia (1.0/0.3%, p=.045), and spinal fluid leakage (2.4/0.4%, p<.001) were also higher in the ADF group, even after matching. The costs were also higher in the ADF group. However, surgical site infection (2.0/3.4%, p=.033) was significantly lower in the ADF group. No significant difference in the reoperation rates was found between the groups.CONCLUSION
The present study, using a large nationwide database, demonstrated that perioperative complications were more common in the ADF group, but that surgical site infection (SSI) was more frequently observed in the LAMP group. 相似文献7.

Introduction
Renal cell carcinoma (RCC) brain metastasis is generally viewed as poor prognostic features and often excludes patients from cytoreductive nephrectomy or participation in clinical trials. We aim to evaluate patients presenting with brain metastasis and their outcomes.Methods
Surveillance Epidemiology and End Results-18 registries database was queried for all patients with metastatic RCC from 2010 to 2014. Patients with renal cancer as their only malignancy were included. Information was available for metastatic disease to bone, liver, lung, and brain. Patients were then further stratified into those with isolated brain metastases and those with additional metastasis to other sites as well. Overall survival was compared between groups using logrank analysis.Results
A total of 6,667 patients were identified with metastatic RCC. Among them, 775 (12.1%) had brain metastasis at time of diagnosis. Of these patients with brain metastasis, 152 (20.4%) had isolated brain metastasis. Only 23.8% of all patients with brain metastasis underwent cytoreductive nephrectomy, compared to 40.8% of patients with isolated brain metastasis. Patients with brain and other metastasis and brain metastasis only treated by cytoreductive nephrectomy exhibited a median survival of 11 and 33 months, respectively. Those patients who did not undergo cytoreductive nephrectomy experienced a median survival of 4 and 5 months, respectively.Conclusion
It appears that selected patients with brain metastasis may experience durable long-term survival. This information may be beneficial for patient counseling, surgical planning, and consideration for inclusion in clinical trials. 相似文献8.

Background
The essence of enhanced recovery after surgery (ERAS) program is the multimodal approach, and many authors have demonstrated safety and feasibility in fast-track bariatric surgery.Objectives
The aim of this study was to evaluate the postoperative pain after the implementation of an ERAS protocol in Roux-en-Y gastric bypass and to compare it with the application of a standard care protocol.Setting
University Hospital Rey Juan Carlos, Madrid, Spain.Methods
A prospective randomized clinical trial of all the patients undergoing Roux-en-Y gastric bypass was performed. Patients were randomized into the following 2 groups: those patients after an ERAS program and those patients after a standard care protocol. Postoperative pain, nausea or vomiting, morbidity, mortality, hospital stay, and analytic acute phase reactants 24 hours after surgery were evaluated.Results
One hundred eighty patients were included in the study, 90 in each group. Postoperative pain (16 versus 37 mm; P < .001), nausea or vomiting (8.9% versus 2.2%; P?=?.0498), and hospital stay (1.7 versus 2.8 d; P < .001) were significantly lower in the ERAS group. There were no significant differences in complications, mortality, and readmission rates. White blood cell count, serum fibrinogen, and C reactive protein levels were significantly lower in the ERAS group 24 hours after surgery.Conclusion
The implementation of an ERAS protocol was associated with lower postoperative pain, reduced incidence of postoperative nausea or vomiting, lower levels of acute phase reactants, and earlier hospital discharge. Complications, reinterventions, mortality, and readmission rates were similar to that obtained after a standard care protocol. 相似文献10.

Objectives
Urothelial cell carcinoma (UCC), a major malignancy of the genitourinary tract, is induced through carcinogenic etiological factors. Endothelial nitric oxide synthase (eNOS) is one of the major isoforms of nitric oxide synthase and is involved in various pathophysiologic and physiologic processes. In this study, eNOS single-nucleotide polymorphisms were investigated to evaluate UCC susceptibility and clinicopathological characteristics.Materials and methods
Two single-nucleotide polymorphisms of eNOS in 431 patients with UCC and 862 controls without cancer were analyzed using real-time polymerase chain reaction.Results
The results showed that 272 men with UCC having eNOS 894 G > T rs1799983 “GT?+?TT” variants had a high risk of developing a large tumor (T1–T4, P?=?0.038). Furthermore, a correlation was observed between the expressions of eNOS and invasive tumor, metastasis and poor survival in urothelial carcinoma in The Cancer Genome Atlas data set.Conclusion
Our results indicated that male patients with UCC carrying eNOS 894 G > T rs1799983 “GT?+?TT” genetic variants have a high risk of developing a large tumor, and eNOS polymorphisms may serve as a marker or therapeutic target in UCC treatment. 相似文献11.

Background
Though intestinal failure (IF) after bariatric surgery (BS) is uncommon, its prevalence is increasing. However, data on the outcomes for these patients are limited.Objectives
To analyze the outcomes of treatment for patients with IF after BS.Setting
University hospital.Methods
A single-center analysis (1991–2016) of outcomes according to treatment arms established by a multidisciplinary team.Results
Twenty-five IF patients were identified (median age 45 yr). BS was 92% Roux-en-Y gastric bypass. The major cause of IF was volvulus/internal hernia (72%). Median time from BS to IF was 48 months. Treatment arms were intestinal rehabilitation (IR, n?=?15), transplantation (TXP, n?=?5), and parenteral nutrition (PN, n?=?5). For IR, median bowel length was 60 cm. Forty-six percent ultimately discontinued PN. Twenty-seven percent were partially weaned PN and 27% failed IR. Common surgical rehabilitation was Roux-en-Y gastric bypass reversal and restoration of gastrointestinal continuity. The 5-year overall survival was 74%. For TXP, 7 patients were listed for TXP (5 initially and 2 after failed IR). Three underwent TXP, 2 isolated intestine and 1 isolated liver. Three were delisted (1 improvement and 2 death). For PN, 6 patients required long-term PN (5 initially and 1 after failed IR). Four patients are alive currently.Conclusions
IF after BS is an increasing problem facing IR centers. Internal hernia is the major cause. Surgical IR is the first-line therapy and affords the best outcome. TXP is reserved for rescuing patients who failed IR or develop PN complications. Long-term PN is suitable for patients in whom IR or TXP is impractical. 相似文献12.

PURPOSE
To characterize the gross, histologic, and systemic changes caused by implantation of metal fragments commonly used in commercial bullets into the intervertebral disc.BACKGROUND CONTEXT
Long-term complications of retained bullet fragments in the spine have been documented in the literature; however, the impact of different metal projectiles on the intervertebral disc has not been described. This study was performed to assess the local effects of the metallic bullet fragments on the intervertebral disc and their systemic effects regarding metal ion concentrations in serum and solid organs.STUDY DESIGN
Animal Model Study.METHODS
Funding for this project was provided by the Cervical Spine Research Society in the amount of $10,000. Copper, lead, and aluminum alloys from commercially available bullets were surgically implanted into sequential intervertebral discs in the lumbar spine of six canines. Kirschner wire implantation and a sham operation were performed as controls. Radiographs were performed to confirm the location of the bullets. Animals were sacrificed at 4, 6, and 9 months postimplantation. Whole blood, plasma, cerebrospinal fluid, kidney tissue, and liver tissue samples were analyzed for copper and lead concentrations. Histologic and gross samples were examined at the time of sacrifice.RESULTS
Significant tissue reactions were noted in the discs exposed to copper and lead. Copper resulted in significantly more severe disc degeneration than either the lead or aluminum alloy. In the short interval follow-up of this study, no statistically significant trend was observed in whole blood, plasma, cerebrospinal fluid, and tissue levels.CONCLUSION
This study demonstrates that the canine intervertebral disc is differentially susceptible to metallic fragments depending on the composition. Trends were noted for increasing levels of lead and copper in liver tissue samples although statistical significance could not be reached due to short time interval and small sample size. The metallic composition of retained fragments can be a determining factor in deciding on surgical intervention. 相似文献13.

Background
Sleeve gastrectomy (SG) is currently the most commonly performed bariatric procedure in the United States; however, it can be associated with development of de novo gastroesophageal reflux (GERD) or worsening of existing GERD. Preoperative esophagogastroduodenoscopy (EGD) and findings of esophagitis are commonly used as screening tool, but the alternative use of preoperative objective measurement of acid reflux has not been studied.Objective
The aim of this study was to evaluate if preoperative objective measurement of acid reflux by using wireless pH monitoring (WPHM) could have an impact on surgical planning and outcomes.Setting
Academic Center of Excellence.Methods
Retrospective review of a prospectively collected database of 43 adult obese patients with reflux symptoms who underwent outpatient EGD and WPHM between September 2011 and September 2017.Results
Change in planned surgical management from SG to Roux-en-Y-gastric bypass with the use of WPHM occurred in 21.0% (n?=?9) of patients. Only 2.3% (n?=?1) developed de novo GERD after SG. Nonerosive reflux disease was the most common esophageal condition on preoperative EGD. EGD, as a single diagnostic tool, appeared insufficient to diagnose acid reflux and help with the decision planning in this patient population.Conclusions
Based on objective data obtained by measurement of GERD, using preoperative WPHM compared with preoperative EGD alone aids in a better patient selection for either SG or Roux-en-Y-gastric bypass. Our cohort with preoperative WPHM required no surgical conversions or revisions. 相似文献14.

BACKGROUND CONTEXT
Transforaminal lumbar interbody fusion (TLIF) is a widely accepted surgical procedure, but cage migration (CM) and cage retropulsion (CR) are associated with poor outcomes.PURPOSE
This study seeks to identify risk factors associated with these serious events.STUDY DESIGN
A prospective observational longitudinal study.PATIENT SAMPLE
Over a 5-year period, 881 lumbar levels in 784 patients were treated using TLIF at three spinal surgery centers.OUTCOME MEASURES
We evaluated the odds ratio of the risk factors for CM with and without subsidence and CR in multivariate analysis.METHODS
Our study classified CM into two subgroups: CM without subsidence and CM with subsidence. Cases of spinal canal and/or foramen intrusion of the cage was defined separately as CR. Patient records, operative notes, and radiographs were analyzed for factors potentially related to CM with subsidence, CM without subsidence, and CR.RESULTS
Of 881 lumbar levels treated with TLIFs, CM without subsidence was observed in 20 (2.3%) and CM with subsidence was observed in 36 (4.1%) patients. Among the CM cases, CR was observed in 17 (17/56, 30.4%). The risk factors of CM without subsidence were osteoporosis (OR 8.73, p < .001) and use of a unilateral single cage (OR 3.57, p < .001). Osteoporosis (OR 5.77, p < .001) and endplate injury (OR 26.87, p < .001) were found to be significant risk factors for CM with subsidence. Risk factors of CR were osteoporosis (OR 7.86, p < .001), pear-shaped disc (OR 8.28, p = .001), endplate injury (OR 18.70, p < .001), unilateral single cage use (OR 4.40, p = .03), and posterior cage position (OR 6.45, p = .04). A difference in overall fusion rates was identified, with a rate of 97.1% (801 of 825) for no CM, 55.0% (11 of 20) for CM without subsidence, 41.7% (15 of 36) for CM with subsidence, and 17.6% (3 of 17) for CR at 1.5 years postoperatively.CONCLUSIONS
Our results suggest that osteoporosis is a significant risk factor for both CM and CR. In addition, a pear-shaped disc, posterior positioning of the cage, the presence of endplate injury and the use of a single cage were correlated with the CM with and without subsidence and CR. 相似文献15.
The clinical implication of gamma globulin levels in patients with nonmuscle-invasive bladder cancer
Objective
The production of antibody, also referred immunoglobulin, is the principal functions of B cells. Gamma globulin fraction determined by serum protein electrophoresis is composed almost entirely of immunoglobulin. This study aimed to investigate the association between gamma globulin level and oncological outcomes in patients with nonmuscle-invasive bladder cancer (NMIBC).Patients and methods
A total of 274 patients with NMIBC who underwent transurethral surgery between 2000 and 2015 were identified. One hundred forty-four patients (52.6%) had received adjuvant intravesical bacillus Calmette-Guérin. Gamma globulin fraction (%) was determined by serum protein electrophoresis, and gamma globulin level (mg/dl) was calculated by multiplying the total protein level (mg/dl) by the gamma globulin fraction (%). The association between gamma globulin levels and oncological outcomes was statistically evaluated.Results
During a median follow-up period of 39 months, 99 (36.1%) patients experienced at least 1 tumor recurrence and 16 (5.8%) patients had disease progression. The median (interquartile range) gamma globulin level was 1.2 (1.0–1.3) mg/dl. Recurrence-free survival rate of patients with gamma globulin levels of ≥1.4 mg/dl was significant lower than that of patients with gamma globulin levels of <1.4 mg/dl (P < 0.01). There was no significant difference in progression-free survival between the 2 groups (P = 0.17). Multivariate analysis revealed that gamma globulin level of ≥1.4 mg/dl is significantly associated with higher recurrence rate (hazard ratio?=?1.83, P < 0.01).Conclusion
Gamma globulin level is significantly associated with tumor recurrence. Our results suggest that B cell immunity may be involved in tumor recurrence in patients with NMIBC. 相似文献16.

Background Context
Underlying cognitive factors have been found to influence patients’ symptom experience. Current evidence suggests that concomitant changes in appraisal must be taken into account to accurately interpret change as measured by standard spine patient-reported outcomes (PROs).Purpose
To investigate changes in patients’ minimally important differences (MID) over recovery from spinal surgery; whether and how cognitive appraisal processes are implicated in the change trajectories.Study Design/Setting
Longitudinal cohort study with up to 12 months follow-up.Patient Sample
Surgical patients (n?=?167) with a diagnosis of disc herniation or spinal stenosis.Outcome Measures
Standard spine patient-reported PROs were used (Rand-36, Oswestry Disability Index, Numerical Rating Scale for pain, PROMIS Pain Impact).Methods
This study was funded by the Feldberg Chair in Spinal Research, Sunnybrook Health Sciences Centre and the authors have no conflicts of interest. MID used an anchor technique and was computed by global assessment of change (GAC) grouping. Participants were binned into groups based on their GAC response patterns at all time points: Consistently better post-surgery, consistently worse post-surgery, and bouncers, whose GAC ratings fluctuate (ie, better-then-worse-then-better; or vice versa). Individuals’ longitudinal quality of life (QOL) and appraisal slope scores were computed. QOL-appraisal slopes’ correlations were computed by GAC group. Fisher's Z transformation tested the hypothesis that GAC groups differed in the QOL-appraisal relationship over time.Results
Moderate to large changes are recognized as clinically important in the early stages of recovery (ie, 6 weeks post-surgery), and over time smaller and smaller changes become important. The three pattern groups emphasized and deemphasized different standards of comparison over time, with the Better group emphasizing personal goals and the Worse and Bouncers deemphasizing doctors’ input. These group differences translated to differential relationships between PRO change and appraisal changes over time.Conclusions
The MID reflects increasingly subtle change over time in PROs. Appraisal may influence how patients experience the same (MID) change over time, with better outcomes associated with emphasizing long-term goals. PRO change seems to be driven by different standards of comparison. Potential avenues for clinical intervention are discussed. 相似文献17.

BACKGROUND CONTEXT
Health literacy, defined as “the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions,” has been demonstrated to affect access to care and appropriate healthcare utilization.PURPOSE
To determine the impact of health literacy in the evaluation and management of patients with chronic low back pain.STUDY DESIGN
Cross sectional.PATIENT SAMPLE
Patients seen at a multisurgeon spine specialty clinic.OUTCOME MEASURES
Oswestry Disability Index, EQ-5D, and Numeric Rating Scales (0–10) for back and leg pain.METHODS
The Newest Vital Sign (NVS) and Health Literacy Survey, Oswestry Disability Index, EQ-5D and pain scales were administered to patients undergoing evaluation and treatment for lumbar degenerative disease in the outpatient setting. Patients were surveyed regarding their use of medication, therapy, and pain management modalities.RESULTS
Of 201 patients approached for participation, 186 completed the health literacy surveys. Thirty (17%) were assessed as having limited literacy, 52 (28%) as possibly having limited literacy and 104 (56%) having adequate literacy based on their NVS scores. The cohort with low NVS scores also had low Health Literacy Survey Scores. Patients with limited literacy had worse back and leg pain scores compared with patients with possibly limited literacy and adequate literacy. Patients with adequate health literacy were more likely to use medications (80% vs. 53%, p?=?.017) and were more likely to see a specialist (34% vs. 17%) compared with those with limited literacy. Patients with limited health literacy were not more likely to see a chiropractor (7% vs. 7%), but reported more visits (19 vs. 8).CONCLUSIONS
Patients with lower health literacy reported worse back and leg pain scores, indicating either more severe disease or a fundamental difference in their responses to standard health-related quality of life measures. This study also suggests that patients with limited health literacy may underutilize some resources and overutilize other resources. Further study is needed to clarify these patterns, and to examine their impact on health status and clinical outcomes. 相似文献18.

Background
Metabolic syndrome (MetS) has been reported to be associated with adverse outcomes in cancer patients. However, the relationship between MetS and upper tract urothelial carcinoma (UTUC) has yet to be explored.Objectives
To investigate the prognostic value of MetS in UTUC after radical nephroureterectomy.Patients and methods
A total of 644 patients with UTUC after radical nephroureterectomy were identified at West China Hospital from May 2003 to December 2016. MetS was defined as the co-existence of 3 or more of 5 components (obesity, hypertension, elevated fasting glucose, decreased high-density lipoprotein-cholesterol, and hypertriglyceridemia). Logistic and Cox regression analyses were performed to evaluate the associations of MetS with pathological features and survival outcomes. Decision curve analysis and Harrell concordance index were used to determine the clinical utility of the prediction models.Results
Of 644 patients, 157 (24.4%) had MetS. Over a median follow-up of 39 months, 269 (41.8%) experienced disease recurrence, 233 (36.2%) died, and 185 (28.7%) died of UTUC. MetS was independently associated with high-grade disease, advanced pT stage (≥pT3), and lymphovascular invasion (each P < 0.05). Multivariate Cox regression analysis showed that MetS was an independent factor for decreased cancer-specific survival (hazard ratio [HR]: 1.38, 95% confidence intervals [CI]: 1.01–1.89, P?=?0.042) but not for recurrence-free survival (HR: 1.27, 95% CI: 0.97–1.67, P?=?0.078), and overall survival (HR: 1.24, 95% CI: 0.95–1.62, P?=?0.121). The estimated c-index of the multivariate models for cancer-specific survival was 0.763 compared with 0.769 when MetS added.Conclusions
MetS is a negative prognostic factor in UTUC. Further studies of MetS in UTUC are demanded. 相似文献19.
