Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

Thyroid function and prevalence of anti-thyroperoxidase antibodies in a population with borderline sufficient iodine intake: influences of age and sex.

Contains fulltext : 50214.pdf (publisher's version ) (Open Access)BACKGROUND: We present a large European population-based study of thyroid function, performed in a population with longstanding borderline sufficient iodine intake. METHODS: The Nijmegen Biomedical Study is a population-based survey conducted in the eastern part of The Netherlands. Randomly selected inhabitants received a postal questionnaire on lifestyle and medical history, which was filled out by 9371 individuals (41.7%). We measured serum thyroid-stimulating hormone (TSH), free thyroxine (FT4), and anti-thyroperoxidase antibodies (TPOAbs) in 6434 responders. A reference population of 5167 individuals was selected by excluding those at risk for thyroid disease. RESULTS: Overt thyrotoxicosis was found in 0.4% of the total population and subclinical thyrotoxicosis in 0.8%. Overt hypothyroidism was found in 0.4% and subclinical hypothyroidism in 4.0%. In individuals older than 60 years, mean FT4 concentrations increased with age. Mean TSH decreased with age, from 1.46 mIU/L at 18-24 years to 1.07 mIU/L after 85 years. The mean TSH in the total population did not differ from the mean TSH in the reference population; the exclusion of those at risk for thyroid disease, however, lowered the upper limit of the TSH reference interval considerably. In the total population, 8.6% of males and 18.5% of females had positive TPOAbs. The presence of TPOAbs was associated with abnormally high and low TSH concentrations. CONCLUSION: In inhabitants of the eastern part of The Netherlands, serum TSH gradually decreases with age, whereas after age 60, serum FT4 increases, possibly because of the development of thyroid autonomy after longstanding borderline sufficient iodine intake

Clinical assessment of emotions in patients with cancer: Diagnostic accuracy compared with two reference standards

Contains fulltext : 220750.pdf (Publisher’s version ) (Open Access)BACKGROUND: Previous research has suggested that clinical assessment of emotions in patients with cancer is suboptimal. However, it is a possibility that well-trained and experienced doctors and nurses do recognize emotions but that they do not evaluate all emotions as necessitating professional mental health care. This implies that the sensitivity of clinical assessment should be tested against the need for professional mental health care as reference standard, instead of emotional distress. We hypothesized that the observed sensitivity of clinical assessment of emotions would be higher when tested against need for professional mental health care as reference standard, compared with emotional distress as reference standard. PATIENTS AND METHODS: A consecutive series of patients starting with chemotherapy were recruited during their routine clinical care, at a department of medical oncology. Clinical assessment of emotions by medical oncologists and nurses was derived from the patient file. Emotional distress and need for professional mental health care were assessed using the Distress Thermometer and Problem List. RESULTS: Clinical assessment resulted in notes on emotions in 42.2% of the patient files with 36.2% of patients experiencing emotional distress and 10.8% expressing a need for professional mental health care (N = 185). As expected, the sensitivity of clinical assessment of emotions was higher with the reference standard "need for professional mental health care" compared with "emotional distress" (P < .001). For specificity, equivalent results were obtained with the two reference standards (P = .63). CONCLUSIONS: Clinical assessment of emotions in patients with cancer may be more accurate than previously concluded

Internet-based treatment for depression in multiple sclerosis: a randomized controlled trial.

Background: Depression in multiple sclerosis (MS) patients is common but may stay untreated. Physical limitations impede face-to-face treatment. Internet-based treatment is therefore a promising tool for treating depression in MS. Objectives: To investigate effectiveness of a guided Internet-based problem-solving treatment (IPST) for depressed MS patients. Methods: MS patients with moderate or severe depressive symptoms were randomly assigned to IPST or a wait list control. Primary outcome was the change in depressive symptoms defined by a change in sum score on the Beck Depression Inventory Second Edition (BDI-II). Assessments took place at baseline (T0), within a week after the intervention (T1), and at 4 months follow-up (T2). Analyses were based on the intention-to-treat principle. Results: A total of 171 patients were randomized to IPST (n = 85) or a wait list control (n = 86). T1 was completed by 152 (89%) and T2 by 131 patients (77%). The IPST group and wait list control showed large significant improvements in depressive symptoms, but no differences were found between groups at T1 (d = 0.23; 95% confidence interval (CI) = (-4.03, 1.08); p = 0.259) and T2 (d = 0.01; 95% CI = (-2.80, 2.98); p = 0.953). Conclusion: We found no indication that IPST for MS patients with moderate or severe depression is effective in reducing depressive symptoms compared to a waiting list. Large improvements in the wait list control were unexpected and are discussed

Sensitivity of fibroblast growth factor 23 measurements in tumor-induced osteomalacia.

CONTEXT: Tumor-induced osteomalacia (TIO) is a paraneoplastic syndrome of hypophosphatemia, decreased renal phosphate reabsorption, normal or low serum 1,25-dihydryxyvitamin-D concentration, myopathy, and osteomalacia. Fibroblast growth factor 23 (FGF23) is a phosphaturic protein overexpressed in tumors that cause TIO and is, at least partly, responsible for the manifestations of TIO. OBJECTIVE: The objective of this study was to determine the sensitivity of FGF23 measurements in TIO. DESIGN: FGF23 concentrations were measured on stored samples with three ELISAs. SETTING: This study was conducted at subspecialty referral centers. PATIENTS: Twenty-two patients with suspected TIO, 13 with confirmed tumors, were studied. INTERVENTIONS: There were no interventions in this study. MAIN OUTCOME MEASURE: FGF23 concentration was the main outcome measure of this study. RESULTS: Elevated FGF23 concentrations were detected using the Immunotopics C-terminal assay in 16 of 22 TIO patients (for a sensitivity of 73%), the Immunotopics Intact assay in five of 22 patients (sensitivity, 23%), and the Kainos Intact assay in 19 of 22 patients (sensitivity, 86%). In the 13 patients with confirmed tumors, the sensitivity was higher with all assays: 92% for the Immunotopics C-terminal assay, 38% for the Immunotopics Intact assay, and 100% for the Kainos assay. CONCLUSION: The Kainos Intact assay was the most sensitive, followed by the Immunotopics C-terminal assay. The findings of normal FGF23 concentrations in some patients with TIO may indicate that FGF 23 is not responsible for the hypophosphatemia in these patients or that FGF23 secretion by some tumors is partially responsive to serum phosphate. Normal FGF23 concentrations should be interpreted in relation to the serum phosphate and 1,25-dihydryxyvitamin-D concentrations
