Lymphocyte to High-density Lipoprotein Cholesterol Ratio is Positively Associated with Pre-diabetes, Metabolic Syndrome, and Non-traditional Cardiometabolic Risk Markers: A Cross-sectional Study at Secondary Health Care.

High scores of lymphocyte-to-high-density lipoprotein cholesterol ratio (lymphocyte-to-HDL-c) may be a new indicator of inflammation and metabolic syndrome. Here, we investigated the associations of the lymphocyte-to-HDL-c with traditional and non-traditional cardiometabolic risk markers in subjects at high cardiovascular risk. This study is a cross-sectional analysis with subjects assisted in a Secondary Health Care (n = 581, age = 63.06 ± 13.86 years; 52.3% women). Lymphocyte-to-HDL-c ratio were assessed by routine laboratory tests. Anthropometric and/or biochemical variables were used to calculate traditional (body mass index - BMI, and waist-to-height ratio - WHtR) and non-traditional (lipid accumulation product index-LAP, visceral adiposity index-VAI, deep-abdominal-adipose-tissue index-DAAT, atherogenic index of plasma-AIP, and waist-hypertriglyceridemic phenotype-HTGW) cardiometabolic risk markers. Furthermore, anthropometric measurement waist circumference (WC), blood pressure, metabolic syndrome (MS), and biochemical markers (lipid and glycemic profile) were considered traditional markers of cardiometabolic risk. Pearson's chi-square test, Poisson regression with robust variance, or multinomial logistic regression were performed (α = 0.05). Individuals with a high lymphocyte-HDL-c ratio (> 0.84, 3rd tertile) were associated with the HTGW phenotype, high VAI, high LAP, hypertriglyceridemia, high AIP, high very low-density lipoprotein-cholesterol (VLDL-c), pre-diabetes, and 3 and 4 MS components compared with individuals in the first tertile, independent of confounders. Our findings supported the lymphocyte-to-HDL-c ratio as a potential biomarker during the screening of subjects at high cardiovascular risk.

Effect of laying on of hands as a complementary therapy for pain and functioning in older women with knee osteoarthritis: A randomized controlled clinical trial.

AIM: To assess the effects of laying on of hands (LooH) as a complementary therapy to kinesiotherapy, on pain, joint stiffness, and functional capacity of older women with knee osteoarthritis (KOA) compared to a control group. METHODS: In this randomized controlled clinical trial, participants were assigned into 3 groups: LooH with a spiritual component ("Spiritist passe" Group - SPG), LooH without a spiritual component (LooH Group - LHG), and a control group receiving no complementary intervention (Control Group - CG). Patients were assessed at baseline, 8 weeks, and 16 weeks. Primary outcomes were joint stiffness and functional capacity (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]), and pain (WOMAC and visual analog scale). Secondary outcomes were anxiety, depression, mobility, and quality of life. Differences between groups were evaluated using an intention-to-treat approach. RESULTS: A total of 120 women (mean age = 69.2 ± 5.2 years) with KOA were randomized (40 participants per group). At 8 weeks, SPG differed significantly from the LHG for WOMAC Functional Status (between-group difference in the change = 0.97; 95% CI: 0.35 to 1.59, P = .001); Anxiety levels (between-group difference in the change = 1.38; 95% CI: 0.11 to 2.65, P = .027); and also from the CG for all outcomes with exception of WOMAC Stiffness. After 16 weeks, SPG differed significantly from the LHG only for WOMAC Functional Status (between-group difference in the change = 0.92; 95% CI: 0.32 to 1.52, P = .001]) and also from the CG for all outcomes with exception of WOMAC Stiffness and timed up-and-go. CONCLUSION: Our results suggest that LooH with a "spiritual component" may promote better long-term functional outcomes than both LooH without a "spiritual component" and a control group without LooH.

Effects of laying on of hands with and without a spiritual context on pain and functionality of older women with knee osteoarthritis: study protocol for a randomized controlled trial / 中西医结合学报

<p><b>BACKGROUND</b>Laying on of hands (LooH) is a culturally-accepted therapy in several traditions. In Brazil, "Spiritism" (third-largest religious tradition in number of followers) uses LooH with the name of "Spiritist Passe" (SP). However, there are few studies assessing SP's role in medical outcomes. The present study aims to investigate the effects of LooH, with and without a spiritual context, on pain, joint stiffness, and functional capacity of older women (≥60 years old) with knee osteoarthritis (KOA).</p><p><b>METHODS/DESIGN</b>In this triple-blind, prospective randomized controlled trial, older women with KOA are assigned to three groups: LooH with a spiritual context group, LooH group without a spiritual context, and a control group receiving no intervention. Patients are assessed by a blinded researcher at baseline, 8 weeks, and 16 weeks. Pain, joint stiffness, and functional capacity are assessed using Western Ontario and McMaster Universities Osteoarthritis Index. Other measures such as anxiety, depression, gait speed, and quality of life will also be assessed. To detect differences between groups, a post-intervention comparison between the three groups and a mean change (post-pre) comparison among the three groups will be done using analysis of variance. All statistical analyses will be performed using an intention-to-treat approach and a per-protocol analysis.</p><p><b>DISCUSSION</b>A pragmatic design using SP, LooH without spiritual context, and no LooH may provide further scientific evidence on SP's feasibility and efficacy for KOA patients.</p><p><b>TRIAL REGISTRATION</b>ClinicalTrials.gov Identifier NCT02917356.</p>

Radiofrequency ablation for single lung tumours not suitable for surgery: seven years' experience.

PURPOSE: This study was done to review recurrence patterns in patients with lung cancer (primary or secondary) treated with percutaneous image-guided radiofrequency (RF) ablation. MATERIALS AND METHODS: From January 2003 to August 2010, 32 patients (24 with primary non-small-cell lung cancer and eight with metastases) with single lung cancer were treated with RF ablation. Post-treatment imaging results were available for each patient. Follow-up was performed using computed tomography (CT) scans at 1, 3, 6, 12, 18 and 24 months after the procedure and annually thereafter. Patterns of recurrence were classified as local, intrapulmonary, nodal, mixed and distant. We evaluated overall survival after RF ablation and the factors associated with recurrence. RESULTS: Seventeen (53.1%) patients showed no evidence of recurrence at follow-up imaging (range 12-72 months; mean, 32.5 months). Recurrence was seen in 15 (46.9 %) patients (range 6-36 months; mean 14.8 months). Local recurrence (40%) after RF ablation was the most frequent. Median disease-free survival was 20 months. Sex, tumour location, tumour size and tumour stage were not associated with a risk of recurrence. Patient age was related to the risk of recurrence (p<0.05). CONCLUSIONS: Local recurrence is the most common pattern in our series. A more aggressive initial RF ablation might offer improvement in outcomes, but this hypothesis needs to be confirmed by larger studies involving a larger number of patients.

Initial experience with percutaneous biopsies of bone lesions using XperGuide cone-beam CT (CBCT): technical note.

PURPOSE: This paper describes our preliminary experience with percutaneous bone biopsy under XperGuide conebeam computed tomography (CBCT) guidance. MATERIALS AND METHODS: Seventeen patients (11 men and 6 women; mean age 57.8; range 17-81) with 17 bone lesions underwent biopsy with XperGuide CBCT (Philips Medical System, Best, The Netherlands). The mean diameter of the lesions was 2.32 cm (range 1-8 cm). Technical success (defined as the correct positioning of the needle within the lesion), diagnostic accuracy, sensitivity and specificity were evaluated. Complication rate was also recorded. RESULTS: The technical success rate was 100%. In 15 patients, a sample of adequate material for histopathological analysis to yield a definitive diagnosis was obtained; in two patients, the sample was inadequate for a definitive diagnosis. In one of these two cases, the lesion was closely followed up for 1 year, during which it remained stable in size, and as a result, it was considered a false positive; the other was considered a false negative. Diagnostic accuracy, sensitivity and specificity were 94.12%, 90.91% and 100%, respectively. No major complications were recorded; only one patient had slight bleeding, with a consequent small haematoma, which reabsorbed in about 15 days. CONCLUSIONS: Bone biopsy under XperGuide CBCT guidance can be considered accurate as a result of the combination of real-time needle orientation and spatial resolution of CT fluoroscopy. Moreover, our results are encouraging in terms of complication rate, diagnostic accuracy, sensitivity, specificity and reduction of CT workload.

Upper urinary tract biopsy: an old device for a new approach.

PURPOSE: The authors sought to evaluate the feasibility, diagnostic accuracy and safety of urological biopsy performed using a flexible alligator forceps. MATERIALS AND METHODS: Twenty-seven patients with suspected urothelial malignancy underwent retrograde biopsy using a 7-F biopsy forceps (Cordis, Miami, FL, USA). Mild sedation was guaranteed by an anaesthesiologist. The final diagnosis was confirmed by cytohistological data and subsequently by pathology findings at surgery. Lesions with benign histopathology were closely monitored for at least 12 months. RESULTS: The technical success rate was 92.6%. The high diagnostic accuracy was related to the positive correspondence between histological outcomes and surgical results or follow-up observations. As regards sample site, the procedure was less successful in calyceal lesions than in lesions located in the upper urinary tract, with a technical success of 71.43%. Twenty patients had asymptomatic haematuria in the early hours after the procedure; ten of them had mild dysuria. No one require medication, and no major complications occurred. CONCLUSIONS: Urological forceps biopsy is a safe and easy procedure. It provides a relatively high level of accuracy in the diagnosis of lesions of the upper urinary tract.

Volumetric analysis of the aneurysmal sac with computed tomography in the follow-up of abdominal aortic aneurysms after endovascular treatment.

PURPOSE: Our aim was to assess the usefulness of volumetric analysis for the follow-up of abdominal aortic aneurysms after endovascular repair (EVAR) and operator independence of the method. MATERIALS AND METHODS: We retrospectively evaluated 99 computed tomography (CT) exams of 33 patients. Two blinded operators assessed the volume before treatment and after EVAR at 1-3 and 12-24 months. Friedman's statistical test was used to assess the reproducibility of the method. The time required for postprocessing by the two operators was compared. RESULTS: One patient was excluded. Twenty-one patients showed no endoleak: 12/21 showed a volume reduction at both follow-up scans (9.7% and 19.5%, respectively); 8/21 showed an early volume increase (9.8%) with a late reduction (10.5%); 1/21 patient showed a volume increase at both follow-up scans (endotension). Eleven patients had an endoleak (one type I, nine type II and one type III); 4/9 type II endoleaks showed a volume reduction at both post-EVAR scans (8.5% and 19.5%). All other cases showed a volume increase after EVAR (type II 15.4%/16.8%, type I 24.1%/9.1%, type III 8%/10.7%). The Friedman statistical test assessed operator independence with p < 0.001. Mean difference between the two operators was 0.9% (0-4.3%). CONCLUSIONS: CT volume analysis is an accurate and reproducible modality for the follow-up of abdominal aortic aneurysms after EVAR. At early follow-up, contrast-enhanced CT remains mandatory to identify small endoleaks. For later follow-up, volumetric analysis would eliminate the need for contrast material in asymptomatic patients with stable or decreasing aneurysm volume.

Complications of microwave and radiofrequency lung ablation: personal experience and review of the literature.

PURPOSE: Complications correlated with percutaneous radiofrequency ablation (RFA) and microwave ablation (MWA) of lung tumours were retrospectively reviewed to compare them with data from the literature and to assess risk factors related with the procedures. MATERIALS AND METHODS: From January 2003 to January 2009, 29 patients (36 lung lesions) were treated with RFA; from January 2007 to January 2009, 16 patients (17 lung lesions) were treated with MWA. Complications recorded at our institution are reported following the Society of Interventional Radiology guidelines. A systematic review of the literature was performed. RESULTS: Any major complication of RFA or MWA was recorded. In agreement with the literature, pneumothorax was the most frequent complication, even though the incidence in our series was lower than reported in the literature (3.5% vs. 4.3-18%). Other complications of RFA were pleural effusion and subcutaneous emphysema. No massive haemorrhages, haemoptysis, abscesses, pneumonia, infections or tumour seeding were recorded in our series. The most common complication of MWA was pneumothorax (25% vs. 39% reported in the literature). Pleural effusion was a common reaction, but therapeutic drainage was never required. CONCLUSIONS: Pneumothorax is the most common complication of both techniques. RFA and MWA are both excellent choices in terms of safety and tolerance.

Ultrasound-guided thermal radiofrequency ablation (RFA) as an adjunct to systemic chemotherapy for breast cancer liver metastases.

PURPOSE: The aim of this study was to evaluate the effectiveness of radiofrequency thermal ablation (RFA) of liver metastases from breast cancer and its impact on survival. MATERIALS AND METHODS: Thirteen female patients (age range 36-82 years; median 54.5 years) underwent RFA for the treatment of 21 liver metastases from breast cancer. The procedures were performed under ultrasound (US) guidance using an RF 2000 or RF 3000 generator system and Le Veen monopolar needle electrodes. Follow-up was carried out by computed tomography (CT) after 1, 3, 6 and 12 months. RESULTS: Technical success was 100%. No major or minor complications occurred at the end of the procedure. In our series, 7/21 lesions in 7/13 patients increased in size at 7, 18, 19 and 38 months. This resulted in a mean disease-free interval of 16.6 months. Mean overall survival after RFA was 10.9 months. CONCLUSIONS: RFA appears to be a useful adjunct to systemic chemotherapy and/or hormone therapy in the locoregional treatment of hepatic metastases from breast cancer. RFA may also be a less invasive alternative to surgery in the locoregional treatment of liver metastases from breast cancer.

MDCT evaluation of the cardiac venous system.

PURPOSE: This study was undertaken to evaluate the usefulness of electrocardiographically (ECG)-gated multidetector-row computed tomography (MDCT) for the assessment of the coronary venous system and detection of its anatomical variants, in order to identify those suitable for lead placement in cardiac resynchronisation therapy (CRT). MATERIALS AND METHODS: We retrospectively examined the coronary MDCT studies of 89 patients (73 males, 16 females, average age 62.5 years, range 31-79) referred for suspected coronary artery disease. The cardiac venous system was assessed in all patients using three-dimensional (3D) postprocessing on a dedicated Vitrea workstation (five patients were excluded from the analysis). RESULTS: The coronary sinus, the great cardiac vein, the anterior interventricular vein and the middle cardiac vein were visualised in all cases. The lateral cardiac vein was visualised in 56/84 patients (67%) and the posterior cardiac vein in 63/84 patients (75%), never both missing. Along the postero-lateral wall of the left ventricle, only one branch was present in 44 cases, two branches in 21 cases and three or more branches in 19/84 cases (22%). Evaluation of the maximum diameter revealed that the lateral vein was dominant over the posterior vein in 20/40 cases. The small cardiac vein was visualised in 11/84 cases. CONCLUSIONS: MDCT provides good depiction of the cardiac venous system, enabling the study of the vessel course and the identification of anatomical variants. Hence, this imaging technique could be proposed for the preoperative planning of CRT in selected patients.
