Abstract Objectives: Hepatoblastoma (HB) is the most common pediatric liver malignancy, typically affecting children within the first 4 years of life. However, only a few validated blood biomarkers are used in clinical evaluation. The current study explored the clinical application and significance of D-dimer levels in patients with HB. Method: Forty-four patients with HB were included in this retrospective study. D-dimer and plasma fibrinogen levels were examined, and their correlation with other clinical features was analyzed. D-dimer and plasma fibrinogen levels were examined between HB and other benign hepatic tumors. Results: D-dimer levels were significantly associated with high-risk HB features, such as advanced stage and high α-fetoprotein (AFP) levels. Higher D-dimer levels were observed in stage 4 patients compared with stage 1/2/3 patients (P = .028). Higher D-dimer levels were also observed in patients with higher AFP levels before chemotherapy compared with patients with lower AFP levels after chemotherapy (P< 0.001). In addition, higher D-dimer levels were observed in HB compared with other benign hepatic tumors such as hepatic hemangioma and hepatocellular adenoma (P = .012). No significant difference in D-dimer levels was found between sex (P = .503) and age (≥12 vs <12 months, P = .424). There was no significant difference in plasma fibrinogen levels between sex or age and high-risk HB features, such as advanced stage and high AFP levels. Conclusions: Elevated D-dimer levels could be a useful determinant biomarker for high-risk features in patients with HB. This finding also supports the clinical application of D-dimer in HB.

Previous studies have predominantly evaluated the effectiveness of inpatient treatment for anorexia nervosa at the group level. The aim of this study was to evaluate treatment outcomes at an individual level based on the clinical significance of improvement. Patients' treatment outcomes were classified into four groups: deteriorated, unchanged, reliably improved and clinically significantly improved. Furthermore, the study set out to explore predictors of clinically significant changes in eating disorder psychopathology. A total of 435 inpatients were assessed at admission and at discharge on the following measures: body-mass-index, eating disorder symptoms, general psychopathology, depression and motivation for change. 20.0-32.0% of patients showed reliable changes and 34.1-55.3% showed clinically significant changes in the various outcome measures. Between 23.0% and 34.5% remained unchanged and between 1.7% and 3.0% deteriorated. Motivation for change and depressive symptoms were identified as positive predictors of clinically significant changes in eating disorder psychopathology, whereas body dissatisfaction, impulse regulation, social insecurity and education were negative predictors. Despite high rates of reliable and clinically significant changes following intensive inpatient treatment, about one third of anorexia nervosa patients showed no significant response to treatment. Future studies should focus on the identification of non-responders as well as on the development of treatment strategies for these patients.

Tumor necrosis factor alpha (TNF-α) is an inflammatory mediator whose levels are increased in the gingival crevicular fluid and blood serum in the case of chronic periodontitis. The aim of this study was to determine the effect of vector ultrasonic system (VUS) on the levels of TNF-α in gingival crevicular fluid (GCF) and the clinical parameters in patients with chronic periodontitis. The study protocol was conducted using split-mouth design in 30 patients with chronic periodontitis. VUS and scaling and root planing (S/RP) were applied separately to 2 quadrants, including the upper and the lower jaws. At baseline and after 6 months, clinical parameters including plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL) were recorded, and concentrations of TNF-α in GCF were determined by enzyme-linked immunosorbent assay (ELISA). Intergroup comparisons were evaluated by the independent Students' t-test, and the Pearson correlation was used to determine the relationship between parameters. The level of significance was set at 5%. Both treatment modalities provided statistically significant improvements in clinical periodontal parameters and TNF-α levels after 6 months (p < 0.05). Also, there were no significant correlations between the TNF-α levels in GCF and the clinical parameters in both treatment group at baseline and at the end of 6 months period (p > 0.05). The use of the vector ultrasonic system in the non-surgical treatment of chronic periodontitis presents beneficial improvements for the clinical attachment level and the probing pocket depth as well as TNF-α levels in GCF.

The aim of this clinical study were to compare the clinical efficacy of ankaferd blood stopper (ABS) when used in combination with autogenous cortical bone graft (ACB) in the treatment of intrabony periodontal defects. The study was planned as a split-mouth design. Fifteen patients with chronic periodontitis at 30 sites (six men, nine women; 42 ± 7 years) were included. Treatment sites had probing pocket depths (PPD) of ≥ 6 mm and osseous defect depths of ≥ 4 mm as radiographically assessed. Following the initial periodontal therapy, patients were randomly assigned to two treatments in contralateral areas of the dentition: ACB + ABS or ACB alone. At baseline and 6 mo after surgery, clinical parameters of plaque index, gingival index, PPD, clinical attachment level and gingival recession (GR) were recorded. The primary outcome variable was the change in clinical attachment level between baseline and 24 wk after surgery. Gingival crevicular fluid samples were collected immediately before surgery and at 2, 4, 6, 12 and 24 wk after the surgery. Gingival crevicular fluid volume was calculated and vascular endothelial growth factor levels in gingival crevicular fluid were measured. PPD decreased, clinical attachment level improved and gingival index decreased significantly in response to both modes of treatment (p < 0.05). Both treatment modalities resulted in a significant gain in radiographic bone levels compared to baseline (p < 0.05). Intergroup comparisons showed that there was a significantly higher gain in clinical attachment level in the ABS/ACB group compared to ACB group (p < 0.05) with significantly less GR (p < 0.05). Similarly, vascular endothelial growth factor concentration in gingival crevicular fluid was significantly higher in the ABS/ACB group at postoperative weeks 2 and 4 compared to the ACB group (p < 0.01). The findings suggest that ABS enhances the soft tissue healing during the periodontal defect fill by the ACB by stimulating angiogenesis and vascular endothelial cell function, prevents GR and thereby increases the clinical attachment gain. © 2015 John Wiley & Sons A/S.

Procalcitonin has been found to be a good marker for the diagnosis of sepsis. However, data on procalcitonin levels to predict the clinical outcome in patients with sepsis are limited. The aim of our study was to estimate serum procalcitonin levels in patients with sepsis and to identify its relationship with the clinical outcome. This was a prospective observational study conducted on 112 patients with sepsis admitted to the medical wards and medical intensive care unit of a tertiary care teaching hospital. Serum procalcitonin was measured at baseline before antibiotic administration and on day 5. The clinical outcome studied was death or survival on day 28. Baseline mean serum procalcitonin was highest in patients with septic shock and lowest in patients having sepsis without organ dysfunction. Mean values of procalcitonin at baseline and on day 5 were significantly higher in non-survivors when compared with survivors. There was a significant difference in the change in procalcitonin levels from baseline to day 5 between survivors and non-survivors, with survivors having declining values on day 5 while non-survivors had increasing values from baseline. The baseline APACHE II and SOFA scores also showed a significant correlation with the baseline procalcitonin level. Declining values of procalcitonin therefore indicate a favourable clinical outcome in patients with sepsis.

Sub-clinical hypothyroidism is a common disease and whether L-thyroxine replacement treatment improves serum lipid levels in affected patients remains controversial. Thus, the aim of the present meta-analysis was to assess the effect of L-thyroxine therapy on serum lipid levels in sub-clinical hyperthyroidism. Relevant randomized controlled trials (RCTs) containing continuous data, published until July 2015 were retrieved from the Cochrane Library, PubMed, Medline, Google Scholar and Embase databases and subjected to meta-analysis using Review Manager software version 5.2 (The Nordic Cochrane Centre, Copenhagen, Denmark). Seven RCTs comprising 319 patients were included. The overall methodological quality of the RCTs was good. Statistical analysis revealed that serum low-density lipoprotein-cholesterol (LDL-C) levels were significantly decreased after L-thyroxine treatment [mean difference (MD): −0.23; 95% confidence interval: −0.44, −0.03; P=0.02], while changes of total cholesterol (TC), triglyceride (TG) and high-density lipoprotein-cholesterol (HDL-C) were not significant (MD: −0.18, P=0.09; MD: −0.02, P=0.78; and MD: −0.06, P=0.14, respectively). In conclusion, the meta-analysis performed in the present study revealed that compared with placebo treatment, L-thyroxine significantly improved serum LDL-C levels in patients with sub-clinical hypothyroidism, while not significantly affecting TC, TG and HDL-C levels.

To investigate detailed patient experiences specific to receiving vascular endothelial growth factor inhibitors (anti-VEGF) for wet age-related macular degeneration (wAMD), and to acquire a snapshot of the frequency of clinically significant levels of depression, anxiety, and posttraumatic stress among patients and levels of burden in patients' carers. Observational cross-sectional mixed-methods study. Three hundred patients with wAMD receiving anti-VEGF treatment and 100 patient carers were recruited. Qualitative data on patients' experience of treatment were collected using a structured survey. Standardized validated questionnaires were used to quantify clinically significant levels of anxiety, depression, and posttraumatic stress, as well as cognitive function and carers' burden. Qualitative data showed that 56% of patients (n = 132) reported anxiety related to anti-VEGF treatment. The main sources of anxiety were fear of going blind owing to intravitreal injections and concerns about treatment effectiveness, rather than around pain. From validated questionnaires, 17% of patients (n = 52) showed clinical levels of anxiety and 12% (n = 36) showed clinical levels of depression. Depression levels, but not anxiety, were significantly higher in patients who received up to 3 injections compared with patients who received from 4 to 12 injections (analysis of variance [ANOVA] P = .027) and compared with patients who received more than 12 injections (ANOVA P = .001). Anti-VEGF treatment is often experienced with some anxiety related to treatment, regardless of the number of injections received. Clinical levels of depression seem to be more frequent in patients at early stages of anti-VEGF treatment. Strategies to improve patient experience of treatment and minimize morbidity are suggested.

The aim of this study was to evaluate the effect of nonsurgical periodontal therapy on clinical parameters and gingival crevicular fluid levels of tissue/blood vessel-type plasminogen activator (t-PA) and plasminogen activator inhibitor-2 (PAI-2) in patients with periodontitis, with or without rheumatoid arthritis (RA). Fifteen patients with RA and chronic periodontitis (RA-P), 15 systemically healthy patients with chronic periodontitis (H-P) and 15 periodontally and systemically healthy volunteers (C) were included in the study. Plaque index, gingival index, probing pocket depth, clinical attachment level, bleeding on probing, gingival crevicular fluid t-PA and PAI-2 levels, erythrocyte sedimentation rate, serum C-reactive protein and disease activity score were evaluated at baseline and 3 mo after mechanical nonsurgical periodontal therapy. All periodontal clinical parameters were significantly higher in the RA-P and H-P groups compared with the C group (p < 0.001) and decreased significantly after treatment (p < 0.001). Pretreatment t-PA levels were highest in the RA-P group and significantly decreased post-treatment (p = 0.047). Pre- and post-treatment PAI-2 levels were significantly lower in controls compared with both periodontitis groups (p < 0.05). Gingival crevicular fluid volume and the levels of t-PA and PAI-2 were significantly correlated. In patients with periodontitis and RA, nonsurgical periodontal therapy reduced the pretreatment gingival crevicular fluid t-PA levels, which were significantly correlated with gingival crevicular fluid PAI-2 levels. The significantly higher t-PA and PAI-2 gingival crevicular fluid levels in periodontal patients, regardless of systemic status, suggest that the plasminogen activating system plays a role in the disease process of periodontitis. © 2016 John Wiley & Sons A/S.

Rheumatoid arthritis (RA) and chronic periodontitis are the most common chronic inflammatory diseases with significant pathological and clinical similarities. Numerous studies have indicated a relationship between rheumatoid arthritis and periodontal disease. The aim of this study was to compare the TNF-α levels in saliva among patients with Rheumatoid arthritis (RA) and chronic periodontitis as well as healthy subjects. One hundred and seventy-one patients were enrolled in this cross-sectional study. Fifty-seven patients diagnosed of RA, 57 patients with chronic periodontitis and 57 healthy subjects. These patients have been examined with regard to TNF-α level from salivary samples. Their teeth were examined with regard to Plaque Index , Gingival Index, probing depth and clinical attachment level.All patients were non-smokers. The results revealed a significant difference in all periodontal parameters among the three groups. The chronic periodontitis group showed a significantly higher value in all clinical periodontal parameters in comparison to both the RA and healthy groups. No significant difference was found between salivary TNF-α level among the three study groups. Patients with chronic periodontitis had the highest periodontal indices. However there was no significant difference regarding the level of salivary TNF-α. Hence, suppression of proinflammatory cytokines might prove beneficial in suppressing periodontal diseases among RA patients.

This study assessed the effects of race and place of residence on clinical trial participation by patients seen at a designated NCI comprehensive cancer center. Clinical trial accrual to cancer case ratios were evaluated using a database of residents at the continental United States seen at The Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins from 2005 to 2007. Place of residence was categorized into 3 nonoverlapping geographic areas: Baltimore City, non–Baltimore City catchment area, and non–catchment area. Controlling for age, sex, county poverty level, and cancer site, significant race and place of residence differences were seen in therapeutic or nontherapeutic clinical trials participation. White non–Baltimore City catchment area residents, the designated reference group, achieved the highest participation rate. Although the test of interaction (control group compared with all others) was not significant, some race–geographic area group differences were detected. In therapeutic trials, most race–place of residence group levels were statistically lower and different from reference; in nontherapeutic trials, race-specific Baltimore City groups participated at levels similar to reference. Baltimore City residents had lower participation rates only in therapeutic trials, irrespective of race. County poverty level was not significant but was retained as a confounder. Place of residence and race were found to be significant predictors of participation in therapeutic and nontherapeutic clinical trials, although patterns differed somewhat between therapeutic and nontherapeutic trials. Clinical trial accruals are not uniform across age, sex, race, place of residence, cancer site, or trial type, underscoring that cancer centers must better understand their source patients to enhance clinical trial participation.

This is a retrospective analysis of data that was collected prospectively from 2 concurrent FDA IDE lumbar arthroplasty clinical trials performed at a single center. To determine if there is a clinical difference between the 1-level ProDisc patients versus the 2-level ProDisc patients at a minimum of 2 years of follow-up. Marnay's work with ProDisc I prompted the U.S. Clinical Trials of the ProDisc II under the direction of the FDA. Disc replacement surgery in the United States has shown promising results for all types of prostheses up to 6 months. Marnay and colleagues showed that their results at 10 years were still promising, and they saw no significant difference between 1-level and multilevel disc replacements. The findings of Ipsen and colleagues suggest that multilevel arthroplasty cases may be less successful than disc replacement at a single level. Patients were part of the FDA clinical trial for the Prodisc II versus circumferential fusion study at a single institution. We identified 27 patients who received ProDisc at 1 level and 32 who received it at 2 levels with at least a 2-year follow-up, for a total of 59 patients. Unpaired t tests were performed on the mean results of Visual Analog Scale, Oswestry Disability Index, SF-36 Healthy Survey Physical Component Summary, and satisfaction using 10-cm line visual scale scores to determine a clinical difference if any between the 2 populations. While patients receiving ProDisc at 2 levels scored marginally lower in all evaluation indexes, score differences in each category were also found to hold no statistical significance. This study was unable to identify a statistically significant difference in outcome between 1- and 2-level ProDisc arthroplasty patients in a cohort from a single center. The equality of clinical effectiveness between 1- and 2-level ProDisc has yet to be determined.

To evaluate the serum levels of leptin and adiponectin in patients with systemic lupus erythematosus (SLE) and correlate their levels with disease activity, presence of autoantibodies and clinical manifestations. 52 women with SLE and 33 healthy women were evaluated. The patients were divided into two groups, the first with active SLE and the second with inactive SLE. Patients with SLEDAI ≥3 were considered active. Serum levels of leptin (ng/ml) and adiponectin (μg/ml) were measured by enzyme immunoassay. There was a significant difference in leptin levels between SLE and controls (20.7 ± 17.1 vs. 8.0 ± 5.0 ng/mL, P <0.001), but no significant difference in adiponectin levels (87.5 ± 69.7 vs. 118.1 ± 70.6 pg/ml, P = 0.053). No significant difference in levels of leptin and adiponectin was noted between inactive and active SLE groups. There was a significant association between low levels of leptin and positivity for anticardiolipin (aCL) (P = 0.025) and lupus anticoagulant (LA) (p = 0.003) and a significant association between high levels of leptin and the presence of renal disease (p <0.001). However, there was no association between adiponectin levels with autoantibodies and clinical features in SLE patients. Patients with SLE had elevated leptin levels, with association with renal involvement. Leptin and adiponectin were not correlated with disease activity. Low levels of leptin have been associated with the presence of LA and aCL. Copyright © 2014 Elsevier Editora Ltda. All rights reserved.

The relationship between apathy and endocrine dysfunction, both frequent outcomes of neurological insult, has not yet been investigated in brain tumor survivors. The present study aimed to assess the relationship between pituitary disorders and apathy and other facets of executive function in long-term adult survivors of childhood brain tumors and to differentiate between apathy and depression in this population. Seventy-six adult survivors of childhood brain tumors at least 5 years past diagnosis participated. An informant completed the Frontal Systems Behavior Scale (FrSBe), and 75 of the 76 participants completed a Structured Clinical Interview for the DSM-IV-TR (SCID). Information on neuroendocrine dysfunction was obtained through medical chart review. Clinically significant levels of apathy on the FrSBe were identified in 41% of survivors. Pituitary dysfunction significantly explained 9% of the variance in apathy scores and affected whether an individual presented with clinical levels of apathy. Pituitary dysfunction predicted higher levels of executive dysfunction but did not impact whether a participant reached clinical levels of executive dysfunction. A past major depressive episode (MDE) significantly predicted current apathy but showed no relationship with pituitary disorders. Radiation treatment predicted pituitary dysfunction but not the differences in apathy or executive functions. Apathy and executive dysfunction in survivors of childhood brain tumors are strongly predicted by pituitary dysfunction, and individuals with pituitary dysfunction are more likely to present with clinical levels of apathy as adults. Clinical levels of apathy may present absent of current depression, and pituitary dysfunction impacts apathy uniquely. © 2016 Wiley Periodicals, Inc.

In 30 patients with periodontitis, a total of 278 teeth exhibiting bleeding on probing, subgingival calculus, and a probing depth between 3-6 mm were examined. For each participant, two treatment types were alternatively applied on the contralateral quadrants: scaling and root planing (SRP) as control, and SRP followed by Er,Cr:YSGG laser application (SRP+laser), as a test method. Five clinical parameters: plaque level, bleeding on probing, probing depth, gingival recession and clinical attachment level were examined at baseline and at 2, 3, 6, 12 months after treatment. Of the total of 1,668 sites examined in all patients, 1,088 sites were found with a probing depth of 3-6 mm. In these sites, differences in clinical parameters between SRP and SRP+laser-treated quadrants were analyzed, assuming the level of p < 0.05 as significant. After 2 months from baseline, the mean probing depth reduction and the clinical attachment level gain were significantly greater in SRP+laser than in SRP quadrants, and remained so throughout the study (p < 0.001). A marked reduction of the bleeding scores occurred in all examined sites, irrespective of the treatment method. However, after 12 months, significantly less teeth exhibited bleeding on probing in SRP+laser quadrants than in SRP quadrants (p < 0.001). The mean plaque and gingival recession levels did not differ between the SRP and SRP+laser quadrants neither before nor after the treatment. The periodontal procedures either using Er,Cr:YSGG laser after SRP or SRP alone, lead to significant improvements in all clinical parameters investigated. However, laser application, as an adjunct to SRP, appeared to be more advantageous.

MicroRNAs (miRNA, miR) have been implicated as promising blood-based biomarkers for schizophrenia patients. This study aimed to clinically validate miRNA as potential schizophrenia biomarkers. Plasma levels of 10 miRNAs were analyzed using qPCR in a cohort of 61 schizophrenia patients and 62 normal controls, as well as 25 patients particularly selected for a six-week antipsychotic treatment course. Positive And Negative Syndrome Scale (PANSS), Global Assessment Scale (GAS) and Clinical Global Impression (CGI) were administered to assess the clinical symptoms. The results demonstrated that a panel of miRNAs consisting of miR-30e, miR-181b, miR-34a, miR-346 and miR-7 had significantly increased expression levels with significant combined diagnostic value (AUC:0.713; sensitivity:35.5%; specificity:90.2%). In response to pharmacological treatment, expression levels of miR-132, miR-181b, miR-432 and miR-30e were significantly decreased. In addition, the improvement of clinical symptomatology was significantly correlated with the changes of miR-132, miR-181b, miR-212 and miR-30e expression levels. Furthermore, the decreases of plasma levels of miR-132 and miR-432 were significantly greater in high-effect subgroup than those in low-effect subgroup after six-week treatment course. We conclude that miR-30e, miR-181b, miR-34a, miR-346 and miR-7 combined as a panel are potentially useful non-invasive biomarkers for schizophrenia diagnosis. Markers miR-132, miR-181b, miR-30e and miR-432 are potential indicators for symptomatology improvements, treatment responses and prognosis for schizophrenia patients. © 2015 Wiley Periodicals, Inc.

The clinical significance of the measurement of plasma transferrin (Tf) in patients with hypophysial disorders was reported in our previous papers. In the present study, we determined plasma Tf levels in 55 patients with various endocrine states and considered their clinical significance compared with plasma somatomedin-C (SM-C) levels. Plasma Tf levels decreased significantly in patients with anorexia nervosa (p less than 0.02), hyperthyroidism (p less than 0.05), primary hypothyroidism (p less than 0.05) and Cushing's syndrome (p less than 0.05), while they were elevated significantly in pregnancy (p less than 0.01) or females using estrogens (p less than 0.05). The former two declines were considered a reflection of the malnutritional state of the patients since a significant negative correlation was observed between plasma Tf levels and the percentile deficit from the ideal body weight in patients with anorexia nervosa (p less than 0.01), or between plasma Tf levels and elevated T3 levels which induce hypermetabolism in patients with hyperthyroidism (p less than 0.01). A significant correlation was observed between the SM-C and Tf levels in these subjects (including normal controls and patients with hypophysial disorders) as a whole (r = 0.79, p less than 0.001). These data indicate that plasma Tf is changeable according to the endocrinological and nutritional conditions with good correlation to the SM-C, and it is suggested that Tf also operates as a growth factor in vivo.

The role of oxidative stress in the initiation and progression of myelodysplastic syndromes (MDS) as a consequence of iron overload remains unclear. In this study we have simultaneously quantified plasma low-molecular-weight aminothiols, malondialdehyde, nitrite, and nitrate and have studied their correlation with serum iron/ferritin levels, patient treatment (chelation therapy), and clinical outcomes. We found significantly elevated plasma levels of total, oxidized, and reduced forms of cysteine (P < 0.001) , homocysteine (P < 0.001), and cysteinylglycine (P < 0.006) and significantly depressed levels of total and oxidized forms of glutathione (P < 0.03) and nitrite (P < 0.001) in MDS patients compared to healthy donors. Moreover, total (P < 0.032) and oxidized cysteinylglycine (P = 0.029) and nitrite (P = 0.021) differed significantly between the analyzed MDS subgroups with different clinical classifications. Malondialdehyde levels in plasma correlated moderately with both serum ferritin levels (r = 0.78, P = 0.001) and serum free iron levels (r = 0.60, P = 0.001) and were significantly higher in patients with iron overload. The other analyzed compounds lacked correlation with iron overload (represented by serum iron/ferritin levels). For the first time our results have revealed significant differences in the concentrations of plasma aminothiols in MDS patients, when compared to healthy donors. We found no correlation of these parameters with iron overload and suggest the role of oxidative stress in the development of MDS disease. PMID:24669287

We found significantly elevated plasma levels of total, oxidized, and reduced forms of cysteine (P < 0.001), homocysteine (P < 0.001), and cysteinylglycine (P < 0.006) and significantly depressed levels of total and oxidized forms of glutathione (P < 0.03) and nitrite (P < 0.001) in MDS patients compared to healthy donors. Moreover, total (P < 0.032) and oxidized cysteinylglycine (P = 0.029) and nitrite (P = 0.021) differed significantly between the analyzed MDS subgroups with different clinical classifications. Malondialdehyde levels in plasma correlated moderately with both serum ferritin levels (r = 0.78, P = 0.001) and serum free iron levels (r = 0.60, P = 0.001) and were significantly higher in patients with iron overload. The other analyzed compounds lacked correlation with iron overload (represented by serum iron/ferritin levels). For the first time our results have revealed significant differences in the concentrations of plasma aminothiols in MDS patients, when compared to healthy donors. We found no correlation of these parameters with iron overload and suggest the role of oxidative stress in the development of MDS disease.

Inflammation may be involved in the pathophysiology of schizophrenia. However, few cross-sectional or longitudinal studies have examined changes in biomarker expression to evaluate diagnostic and prognostic efficacy in acute-stage schizophrenia. We compared serum inflammatory biomarker concentrations in 87 patients with acute-stage schizophrenia on admission to 105 age-, sex-, and body mass index (BMI)-matched healthy controls. The measured biomarkers were soluble tumor necrosis factor receptor 1 (sTNFR1) and adiponectin, which are associated with inflammatory responses, and pigment epithelium-derived factor (PEDF), which has anti-inflammatory properties. We then investigated biomarker concentrations and associations with clinical factors in 213 patients (including 42 medication-free patients) and 110 unmatched healthy controls to model conditions typical of clinical practice. Clinical symptoms were assessed using the Brief Psychiatric Rating Scale and Global Assessment of Function. In 121 patients, biomarker levels and clinical status were evaluated at both admission and discharge. Serum sTNFR1 was significantly higher in patients with acute-stage schizophrenia compared to matched controls while no significant group differences were observed for the other markers. Serum sTNFR1 was also significantly higher in the 213 patients compared to unmatched controls. The 42 unmedicated patients had significantly lower PEDF levels compared to controls. Between admission and discharge, sTNFR1 levels decreased significantly; however, biomarker changes did not correlate with clinical symptoms. The discriminant accuracy of sTNFR1 was 93.2% between controls and patients, showing no symptom improvement during care. Inflammation and a low-level anti-inflammatory state may be involved in both schizophrenia pathogenesis and acute-stage onset. High serum sTNFR1 in the acute stage could be a useful prognostic biomarker for treatment response in clinical practice. Copyright © 2017 Elsevier Inc. All rights reserved.

The presentation of sarcoidosis can involve symptoms from all organs and the diagnosis is therefore often difficult. A raised serum level of serum angiotensin-converting enzyme (sACE) can be detected in 41-58% of patients. However, whether the sACE level per se reflects the severity of the sarcoid inflammation at the onset of the disease is not well described. The purpose of this study was to investigate the clinical and laboratory significance of high versus normal sACE levels in sarcoidosis. Journal data were retrospectively extracted from 101 patients from our clinic. Clinical and biochemical data were compared between patients with high sACE levels (> 115 U/L) on at least one occasion and normal sACE levels (< 115 U/L). In total, 48% (n = 48) of the patients had high ACE and 52% (n = 53) had normal ACE. The most common extrapulmonary manifestation for both groups was arthritis, followed by skin and eye involvement, but none of these differed between the two groups. Serum ionized calcium was significantly higher in the high sACE group, with a correlation coefficient of 0.112 (p = 0.460). Our study demonstrates that serum ionized calcium is significantly higher in the high sACE group but there was no statistical correlation to sACE. No other clinical or biochemical differences were observed.

The purpose of this study was to evaluate predictors of reduction in ammonia levels by occlusion of portosystemic shunts (PSS) in patients with cirrhosis. Forty-eight patients with cirrhosis (21 women, 27 men; mean age, 67.8 years) with PSS underwent balloon-occluded retrograde transvenous obliteration (BRTO) at one institution between February 2008 and June 2014. The causes of cirrhosis were hepatitis B in one case, hepatitis C in 20 cases, alcohol in 15 cases, nonalcoholic steatohepatitis in eight cases, and other conditions in four cases. The Child-Pugh classes were A in 24 cases, B in 23 cases, and C in one case. The indication for BRTO was gastric varices in 40 cases and hepatic encephalopathy in eight cases. Testing was conducted before and 1 month after the procedure. Statistical analyses were performed to identify predictors of a clinically significant decline in ammonia levels after BRTO. Occlusion of PSS resulted in a clinically significant decrease in ammonia levels accompanied by increased portal venous flow and improved Child-Pugh score. Univariate analyses showed that a reduction in ammonia levels due to BRTO was significantly related to lower plasma glucose levels, higher RBC counts, and higher hemoglobin concentration before the treatment. Furthermore, multivariate logistic regression identified preoperative plasma glucose level as the strongest independent predictor of a significant ammonia reduction in response to BRTO. In addition, although BRTO resulted in significantly declined ammonia levels in patients with normal glucose tolerance before the procedure, ammonia levels were not significantly decreased after shunt occlusion in patients with diabetes mellitus or impaired glucose tolerance before BRTO, according to 75-g oral glucose tolerance test results. Preoperative plasma glucose level is a useful predictor of clinically significant ammonia reduction resulting from occlusion of PSS in patients with cirrhosis. Even if PSS are present, control of blood ammonia levels by BRTO alone may be difficult in patients with glucose intolerance.

The relationships of students' preadmission academic variables, sex, undergraduate major, and undergraduate institution to academic performance in medical school have not been thoroughly examined. To determine the ability of students' preadmission academic variables to predict osteopathic medical school performance and whether students' sex, undergraduate major, or undergraduate institution influence osteopathic medical school performance. The study followed students who graduated from New York College of Osteopathic Medicine of New York Institute of Technology in Old Westbury between 2003 and 2006. Student preadmission data were Medical College Admission Test (MCAT) scores, undergraduate grade point averages (GPAs), sex, undergraduate major, and undergraduate institutional selectivity. Medical school performance variables were GPAs, clinical performance (ie, clinical subject examinations and clerkship evaluations), and scores on the Comprehensive Osteopathic Medical Licensing Examination-USA (COMLEX-USA) Level 1 and Level 2-Clinical Evaluation (CE). Data were analyzed with Pearson product moment correlation coefficients and multivariate linear regression analyses. Differences between student groups were compared with the independent-samples, 2-tailed t test. A total of 737 students were included. All preadmission academic variables, except nonscience undergraduate GPA, were statistically significant predictors of performance on COMLEX-USA Level 1, and all preadmission academic variables were statistically significant predictors of performance on COMLEX-USA Level 2-CE. The MCAT score for biological sciences had the highest correlation among all variables with COMLEX-USA Level 1 performance (Pearson r=0.304; P<.001) and Level 2-CE performance (Pearson r=0.272; P<.001). All preadmission variables were moderately correlated with the mean clinical subject examination scores. The mean clerkship evaluation score was moderately correlated with mean clinical examination results (Pearson r=0.267; P<.001) and COMLEX-USA Level 2-CE performance (Pearson r=0.301; P<.001). Clinical subject examination scores were highly correlated with COMLEX-USA Level 2-CE scores (Pearson r=0.817; P<.001). No statistically significant difference in medical school performance was found between students with science and nonscience undergraduate majors, nor was undergraduate institutional selectivity a factor influencing performance. Students' preadmission academic variables were predictive of osteopathic medical school performance, including GPAs, clinical performance, and COMLEX-USA Level 1 and Level 2-CE results. Clinical performance was predictive of COMLEX-USA Level 2-CE performance.

Non-infectious uveitis can cause chronic relapsing and remitting ocular inflammation, which may require high dose systemic immunosuppression to prevent severe sight loss. It has been classically described as an autoimmune disease, mediated by pro-inflammatory Th1 and Th17 T-cell subsets. Studies suggest that natural immunosuppressive CD4 + CD25 + FoxP3 + T-regulatory cells (Tregs) are involved in resolution of inflammation and may be involved in the maintenance of clinical remission. To investigate whether there is a peripheral blood immunoregulatory phenotype associated with clinical remission of sight-threatening non-infectious uveitis by comparing peripheral blood levels of Treg, Th1, and Th17, and associated DNA methylation and cytokine levels in patients with active uveitic disease, control subjects and patients (with previously active disease) in clinical remission induced by immunosuppressive drugs. Isolated peripheral blood mononuclear cells (PBMC) from peripheral blood samples from prospectively recruited subjects were analyzed by flow cytometry for CD3, CD4, FoxP3, TIGIT, T-bet, and related orphan receptor γt. Epigenetic DNA methylation levels of FOXP3 Treg-specific demethylated region (TSDR), FOXP3 promoter, TBX21, RORC2, and TIGIT loci were determined in cryopreserved PBMC using a next-generation sequencing approach. Related cytokines were measured in blood sera. Functional suppressive capacity of Treg was assessed using T-cell proliferation assays. Fifty patients with uveitis (intermediate, posterior, and panuveitis) and 10 control subjects were recruited. The frequency of CD4 + CD25 + FoxP3 + Treg, TIGIT + Treg, and T-bet + Treg and the ratio of Treg to Th1 were significantly higher in remission patients compared with patients with active uveitic disease; and TIGIT + Tregs were a significant predictor of clinical remission. Treg from patients in clinical remission demonstrated a high level of in vitro suppressive function compared with Treg from control subjects and from patients with untreated active disease. PBMC from patients in clinical remission had significantly lower methylation levels at the FOXP3 TSDR, FOXP3 promoter, and TIGIT loci and higher levels at RORC loci than those with active disease. Clinical remission was also associated with significantly higher serum levels of transforming growth factor β and IL-10, which positively correlated with Treg levels, and lower serum levels of IFNγ, IL-17A, and IL-22 compared with patients with active disease. Clinical remission of sight-threatening non-infectious uveitis has an immunoregulatory phenotype characterized by upregulation of peripheral Treg, polarized toward T-bet and TIGIT. These findings may assist with individualized therapy of uveitis, by informing whether drug therapy has induced phenotypically stable Treg associated with long-term clinical remission.

Background: Clinical competency is one of the most important requirements in nursing profession, based on which nurses are assessed. To obtain an effective and improved form of clinical competency, several factors are observed and monitored by the health educational systems. Among these observed factors, spiritual intelligence is considered as one of the most significant factors in nurses’ success and efficacy. In this study, it is aimed to determine the spiritual intelligence status and its relationship with clinical competency. Materials and Methods: The descriptive–correlational research was carried out on 250 nurses in Mashhad educational hospitals, selected by multi-stage sampling. Demographic, clinical competency, and spiritual intelligence questionnaires were used for data collection and 212 questionnaires were analyzed. Results: About 53.3% of nurses obtained above average scores in spiritual intelligence. Clinical competency was evaluated by both self-evaluation and head nurse evaluation methods. Most nurses (53.8%) were having good level of clinical competency based on self-evaluation, 48.2% were at average level based on head nurse evaluation, and 53.3% were at average level based on overall score. A significant correlation was found between spiritual intelligence and clinical competency. Conclusions: In this study, the positive significant correlation between nurses’ spiritual intelligence and their clinical competency is investigated. Because of the positive effects of spiritual intelligence on nurses’ clinical competency and quality of care, it is recommended to develop nurses’ spiritual intelligence during their education and by way of continuous medical education.

Oxidative stress has been associated in several inflammatory conditions and incriminated in the pathogenesis of many diseases. However, little information is available on the status of plasma antioxidant levels, essential components of important antioxidant enzymes such as copper, zinc and selenium in blood, and the end product of oxidative damage to the erythrocytic polyunsaturated fatty acids in inflammatory udder conditions. Blood samples were collected from three groups of dairy cows, with 21 in each group: animals with healthy udder, clinical mastitis, and subclinical mastitis. These animals were randomly selected from a herd on the basis of the California mastitis test, somatic cell count and total bacterial count. The mean plasma ascorbic acid concentration was significantly lower in cows with subclinical (p = 0.004) and clinical mastitis (p = 0.000) and the erythrocytic lipid peroxide levels were significantly (p = 0.000) higher in clinical mastitis as compared to controls. There was a significant decrease in mean blood zinc concentration in subclinical (p = 0.005) and clinical mastitis (p = 0.000), but an increase in mean blood copper level in the clinical mastitis group. It was concluded that the blood antioxidant status declines in inflammatory udder conditions, suggesting that incorporation of antioxidants may help in better management of mastitis in dairy cows.

This study examined the DSM-5 severity criterion for bulimia nervosa (BN) based on the frequency of inappropriate weight compensatory behaviors. 199 community volunteers classified with BN were categorized using DSM-5 severity levels and compared on demographic and clinical variables. 77 (39%) participants were categorized as mild, 68 (34%) as moderate, 32 (16%) as severe, and 22 (11%) as extreme. The severity groups did not differ significantly in demographic variables or body mass index. Shape and Weight concerns did not differ significantly across severity groups. Binge eating differed with the extreme group having significantly higher frequency than the severe, moderate, and mild groups, which did not differ from each other. Restraint differed with the extreme group having significantly higher levels than the mild group. Eating concerns differed with the extreme group having significantly higher levels than moderate and mild groups. Depression differed with the extreme group having significantly higher levels than severe, moderate, and mild groups, which did not differ from each other. Findings from this non-clinical group provide new, albeit modest, support for DSM-5 severity rating for BN based on frequency of inappropriate weight compensatory behaviors. Statistical findings indicate that differences in collateral clinical variables associated with the DSM-5 severity ratings reflect small effect sizes. Further research is needed with treatment-seeking patient groups with BN to establish the validity of the DSM-5 severity specifier and should include broader clinical and functional validators.

Cervical disc arthroplasty (CDA) with Discover prosthesis or anterior cervical discectomy and fusion (ACDF) with Zero-P cage has been widely used in the treatment of cervical spondylotic myelopathy (CSM). However, little is known about the comparison of the 2 zero-profile implants in the treatment of single-level CSM. The aim was to compare the clinical outcomes and radiographic parameters of CDA with Discover prosthesis and ACDF with Zero-P cage for the treatment of single-level CSM. A total of 128 consecutive patients who underwent 1-level CDA with Discover prosthesis or ACDF with Zero-P cage for single-level CSM between September 2009 and December 2012 were included in this study. Clinical outcomes were evaluated using the Japanese Orthopaedic Association (JOA) score and Neck Disability Index (NDI). For radiographic assessment, the overall sagittal alignment (OSA), functional spinal unit (FSU) angle, and range of motion (ROM) at the index and adjacent levels were measured before and after surgery. Additionally, the complications were also recorded. Both treatments significantly improved all clinical parameters (P < 0.05), without statistically relevant differences between the 2 groups. The OSA and FSU angle increased significantly in both groups (P <0.05). Compared with Zero-P group, ROMs at the index levels were well maintained in the Discover group (P < 0.05). However, there were no statistical differences in the ROMs of adjacent levels between the 2 groups (P > 0.05). Besides, no significant differences existed in dysphagia, subsidence, or adjacent disc degeneration between the 2 groups (P > 0.05). However, significant differences occurred in prosthesis migration in CDA group. The results of this study showed that clinical outcomes and radiographic parameters were satisfactory and comparable with the 2 techniques. However, more attention to prosthesis migration of artificial cervical disc should be paid in the postoperative early-term follow-up.

Mild hypercholesterolemia, normal plasma triglycerides, and normal glucose levels across dementia staging in Alzheimer's disease: a clinical setting-based retrospective study.

We examined retrospectively the concurrent relationships between fasting plasma total cholesterol, triglycerides, and glucose levels, and Alzheimer's disease (AD), in a clinical setting-based study. Total cholesterol level was higher in patients with AD compared to elderly controls; triglycerides or glucose levels did not significantly differ between the 2 groups. Respective plotted trajectories of change in cholesterol level across age were fairly parallel. No significant difference in total cholesterol levels was recorded between patients with AD classified by the Clinical Dementia Rating (CDR) score subgroups. These results suggest that patients with AD have relative mild total hypercholesterolemia, normal triglyceridemia, and normal fasting plasma glucose level. Mild total hypercholesterolemia seems to be permanent across age, and across dementia severity staging, and fairly parallels the trajectory of age-related change in total cholesterolemia of healthy controls. We speculate that these biochemical parameters pattern may be present long before-a decade at least-the symptomatic onset of the disease.

To explore the clinical significance of calcitonin gene-related peptide (CGRP) levels in patients with chronic periodontitis before and after treatment, and to detect the calcitonin gene-related peptide content in human venous blood. Thirty healthy controls and thirty patients with mild, moderate, severe periodontitis were enrolled from August 2014 to June 2015.CGRP level in the patients' peripheral blood was detected by ELISA. Three months after periodontal treatment, CGRP level in mild, moderate, severe periodontitis patients' peripheral blood was re-examined by ELISA. Then the correlation between calcitonin gene-related peptide and inflammation of chronic periodontitis was analyzed with SPSS 22.0 software package. The content of CGRP in healthy controls was significantly higher than that in patients with periodontitis. With the aggravation of periodontal inflammation, blood level of CGRP decreased gradually, and the lowest was in patients with severe periodontitis (P<0.01). Three months after periodontal treatment, CGRP content was significantly higher compared with that before treatment (P<0.05), but no significant difference was found in patients with different degree of periodontitis (P>0.05). The level of CGRP in venous blood decreased with the increasing severity of chronic periodontitis, and CGRP was negatively correlated with the degree of inflammation of chronic periodontitis. CGRP may be involved in the occurrence and development of chronic periodontitis. CGRP content in serum of patients with chronic periodontitis after treatment was significantly increased, CGRP may be used as the basis for clinical detection of chronic periodontitis.

Objective: In traditional surface rendering (SR) computed tomographic endoscopy, only the shape of endoluminal lesion is depicted without gray-level information unless the volume rendering technique is used. However, volume rendering technique is relatively slow and complex in terms of computation time and parameter setting. We use computed tomographic colonography (CTC) images as examples and report a new visualization technique by three-dimensional gray level mapping (GM) to better identify and differentiate endoluminal lesions. Methods: There are 33 various endoluminal cases from 30 patients evaluated in this clinical study. These cases were segmented using gray-level threshold. The marching cube algorithm was used to detect isosurfaces in volumetric data sets. GM is applied using the surface gray level of CTC. Radiologists conducted the clinical evaluation of the SR and GM images. The Wilcoxon signed-rank test was used for data analysis. Results: Clinical evaluation confirms GM is significantly superior to SR in terms of gray-level pattern and spatial shape presentation of endoluminal cases (p < 0.01) and improves the confidence of identification and clinical classification of endoluminal lesions significantly (p < 0.01). The specificity and diagnostic accuracy of GM is significantly better than those of SR in diagnostic performance evaluation (p < 0.01). Conclusion: GM can reduce confusion in three-dimensional CTC and well correlate CTC with sectional images by the location as well as gray-level value. Hence, GM increases identification and differentiation of endoluminal lesions, and facilitates diagnostic process. Advances in knowledge: GM significantly improves the traditional SR method by providing reliable gray-level information for the surface points and is helpful in identification and differentiation of endoluminal lesions according to their shape and density.

Hyperprolactinemia can be induced by dopamine D2 receptor-binding drugs such as antipsychotic drugs. The author investigated the relationship between changes in prolactin (PRL) and clinical efficacy of risperidone. In this study, 27 acute psychotic inpatients completed a 12-week trial of risperidone. At baseline and at 2, 4, 8, and 12 weeks after beginning medication, the author measured PRL, assessed hyperprolactinemia-related symptoms, and administered the Brief Psychotic Rating Scale (BPRS). Risperidone treatment significantly elevated serum PRL level (range: 26.9 ng/ml-320.0 ng/ml). The increases of PRL in females were higher than males. The changes in serum PRL levels were not significantly correlated with the improvements in total BPRS scores. PRL-related symptoms such as irregular menstruation, galactorrhea, or erectile dysfunction occurred in nine subjects (7 females and 2 males) whose serum PRL levels increase very highly after 2 weeks of risperidone. In conclusion, our study suggests that the changes in serum PRL levels were not significantly correlated with clinical efficacy of risperidone.

To investigate the level of expression and the clinical significance of IL-2 (interleukin-2), IL-6 (interleukin-6) and TGF-β (transforming growth factor-β) in elderly patients with goiter and hyperthyroidism. Gender, age, course of disease, BMI (Body Mass Index), serum FT3 (Free triiodothyronine-3), FT4 (Free triiodothyronine-4), TT3 (Total triiodothyronine-3), TT4 (Total triiodothyronine-4), TSH (Thyroid Stimulating Hormone) and clinical manifestations on admission and other general clinical data and laboratory examination results were collected and statistically analyzed as case group in 128 elderly patients with goiter and hyperthyroidism. Additional 128 over 60-year-old patients with hyperthyroidism were selected as control group. The thyroid tissue of these patients and the control group were examined by fine needle aspiration biopsy. The expressions of IL-2, IL-6, TGF-β of the thyroid tissue in all patients were detected by immunohistochemistry, qRT-PCR (Real-time Quantitative Polymerase Chain Reaction) and Western blot method respectively, and the statistical analysis was carried out. p < 0.05 indicated that the difference had statistical significance. Compared with the control group, the expressions of IL-2, IL-6 and TGF-β in the group of patients were significantly higher (p < 0.05). The significantly higher expression of IL-2, IL-6, and TGF-β was mainly concentrated in the thyroid follicular cells of patients with hyperthyroidism and thyroid enlargement (p < 0.05). In the patients with goiter, hyperthyroidism, and symptoms of exophthalmos, the level of expression of IL-6 was significantly higher than that of patients without exophthalmos (p < 0.05). In the patients with goiter, hyperthyroidism and symptoms of exophthalmos, and the patients with goiter, hyperthyroidism without symptoms of exophthalmos, IL-2 and TGF-β expression level were not different (p > 0.05). The expression levels of IL-2, IL-6, and TGF-β were significantly increased in the patients with senile goiter and hyperthyroidism, but in the senile patients with goiter, hyperthyroidism and exophthalmos symptoms, IL-6 levels were significantly higher than those without exophthalmos. The use of IL-2, IL-6, and TGF-β is of great significance in the diagnosis of goiter with hyperthyroidism, especially for elderly patients with atypical clinical symptoms of hyperthyroidism.

Objective To evaluate the accuracy of detecting clinically significant retinopathy of prematurity (ROP) using wide-angle digital retinal photography. Methods Literature searches of PubMed and the Cochrane Library databases were conducted last on December 7, 2010, and yielded 414 unique citations. The authors assessed these 414 citations and marked 82 that potentially met the inclusion criteria. These 82 studies were reviewed in full text; 28 studies met inclusion criteria. The authors extracted from these studies information about study design, interventions, outcomes, and study quality. After data abstraction, 18 were excluded for study deficiencies or because they were superseded by a more recent publication. The methodologist reviewed the remaining 10 studies and assigned ratings of evidence quality; 7 studies were rated level I evidence and 3 studies were rated level III evidence. Results There is level I evidence from ≥5 studies demonstrating that digital retinal photography has high accuracy for detection of clinically significant ROP. Level III studies have reported high accuracy, without any detectable complications, from real-world operational programs intended to detect clinically significant ROP through remote site interpretation of wide-angle retinal photographs. Conclusions Wide-angle digital retinal photography has the potential to complement standard ROP care. It may provide advantages through objective documentation of clinical examination findings, improved recognition of disease progression by comparing previous photographs, and the creation of image libraries for education and research.

Metabolic Syndrome (MS) and chronic oral condition (periodontitis [PD]) are state of inflammation. The study was conducted to determine alterations in serum and salivary cytokines level in MS and/or chronic PD in the North Indian population. This cross-sectional study carried out in northern part of India. The study subjects of similar ethnicity were recruited according to International Diabetes Federation (IDF) criteria for MS, while chronic PD was diagnosed on the basis of packet depth and clinical attachment level. ELISA method was employed to assess cytokine level. All subjects were divided in four groups Gr A (MS + PD), B (MS), C (PD), and a control Gr D. The serum and salivary tumor necrosis factor alpha (TNF-α) level in Gr A, B, and C was significantly higher than Gr D (P < 0.05). Serum interleukin-10 (IL-10) level in Gr A, B, and C was lower than Gr D (P < 0.05), but this difference was not significant between Gr C and Gr D. Serum IL-10 level in Gr A was significantly lower than Gr C (P < 0.05). Salivary IL-10 level was not significantly altered in any group. Proinflammatory marker TNF-α has correlation with clinical parameters in patients of MS having PD. The study suggests level of salivary TNF-α may be utilized as a surrogate marker of MS and PD. © 2016 Wiley Periodicals, Inc.

Serum alpha-fetoprotein (AFP) level is normal in 30-40% of hepatocellular carcinoma (HCC) patients, and knowledge on its characteristics and clinical outcome is limited. The purpose of this observational study was to determine the clinical presentation, biological behavior and outcome of HCC patients with normal AFP level. Data of 112 consecutive HCC patients with normal AFP level were analyzed retrospectively. Statistical analysis including survival and factors associated with serum AFP level were performed by Kaplan-Meier method and t-test, respectively. Hepatitis B virus infection exited in 83.0% of all 112 HCC patients with normal AFP level. During a mean 52 ± 20 months (range 5-85 months) follow-up, the 1-, 2-, 3-year overall survival (OS) rate was 97.2%, 85.3% and 81.7%, respectively. The OS rates at 3 years stratified by stages at diagnosis were 100%, 96.2%, 85.7%, 11.1% and 0%, respectively for Barcelona Clinic Liver Cancer (BCLC) stage 0-D diseases. Significant difference in OS was observed among patients with BCLC stage 0-D diseases, P < 0.05. Using 8.78 ng/mL as the cut off value, serum AFP level elevated beyond normal figure during follow-up (AFP conversion) in 16 patients, which related with deterioration of liver function, quantitative changes of T helper cell subsets, rapid tumor progression and shorter survival. Patients with sustained normal AFP level had better survival than patients with AFP conversion, P < 0.05. There was significant difference between the time of diagnosis with HCC to serum AFP level elevation and the time of AFP elevation to death, P < 0.05. Prognosis of HCC patients with normal AFP level was relatively optimal. Serum AFP level elevation during follow-up was significantly associated with clinical outcome in terms of OS. © 2017 John Wiley & Sons Australia, Ltd.

We evaluated serum level of S100B in 11 patients with subcortical vascular dementia (SVD) and 19 patients with subcortical vascular mild cognitive impairment (SVMCI). Comparable groups were age-matched (79.18 +/- 7.76 in SVD group, 77.84 +/- 3.83 in SVMCI; P = 0.53). 22 patients were assessed after 1 month therapy. It was shown that the serum S100B level significantly increased--(0.065 +/- 0.020) micro/l (P = 0.0005) in SVD patients comparing to SVMCI ones - (0.043 +/- 0.010) microg/l. S100B level was significantly correlated with the clinical parameters: MMSE performance (r(s) = -0.61), CDR (r(s) = 0.58), attention task (r(s) = -0.46), pseudobulbar syndrome severity (r(s) = 0.37) and walking alteration (r(s)= 0.37). In patients with reduction of S100B level due to therapy (positive dynamics, n = 12) we registered significant improvement of some clinical parameters: MMSE, attention level, walking. In patients with increasing of S100B level (negative dynamics, n = 10) we didn't registered improvement of any clinical parameters. We made the conclusion that the serum level of S100B could be used as marker of progression SVMCI into SVD and therapy effectiveness.

This study determined the correlations of CXC ligand 16 (CXCL16) and tumor necrosis factor-α (TNF-α) levels with coronary atherosclerotic heart disease (CAHD) and screened for new clinical markers for the prognosis and treatment of the disease. Eighty patients with coronary heart disease and 50 healthy subjects were enrolled into a CAHD or healthy control group, respectively. Computed tomography (CT) coronary angiography and Gensini integral were used to classify plaques and evaluate patients with coronary heart disease. The serum levels of CXCL16 and TNF-α of subjects in each group were detected by enzyme-linked immunosorbent assays (ELISA), and the correlation between levels and clinical markers (such as blood pressure, glucose, lipid and heart rate) and the severity of disease were analyzed. Our results showed the serum levels of CXCL16 and TNF-α were significantly higher in the CAHD group than those in the CK group. The serum CXCL16 levels of the CAHD group patients with plaques were distinctly higher than those of the CADH group patients without plaques, but there were no significant difference in serum TNF-α levels between these two groups of patients. The level of CXCL16 had a significantly positive correlation with the severity of disease, but there was no significant correlation between TNF-α level and the severity of disease. Also, there was no significant correlation between the CXCL16 levels and blood pressure, blood glucose, heart rate, total cholesterol, triglyceride or high-density lipoprotein cholesterol, but there was a clear correlation with the low-density lipoprotein cholesterol. Finally no significant correlations were found between TNF-α levels and each of the clinical markers studied. Based on our findings, the levels of CXCL16 and TNF-α in the patients with coronary heart disease were abnormally increased and the level of CXCL16 correlated closely with the severity of disease. These markers seem to be reliable biological markers for prognosis and disease evaluation in coronary heart disease patients.

In 2010, Veterans Health Administration (VHA) primary care clinics adopted a patient-centered medical home (PCMH) model. This study sought to examine the association between the organizational features related to adoption of PCMH and the level of adherence to oral hypoglycemic agents (OHAs) among patients with diabetes. This retrospective cohort study involved 757 VA clinics that provide primary care to 440,971 patients with diabetes who were taking OHAs in fiscal year 2012. One-year refill-based medication possession ratios (MPRs) were calculated at the patient level. Clinic-level adherence was defined as the proportion of clinics with MPR ≥80%. Risk adjustment of adherence was performed using logistic regression to account for differences in patient populations at clinics. Eight domains of the PCMH model (ie, access, continuity, coordination, teamwork, comprehensive care, self-management, communication, shared decision making) were assessed using items from a previously validated index. Multivariate linear regression was applied to identify PCMH components associated with clinic-level adherence. Patients with diabetes per clinic ranged from 100 to 5011. The average level of adherence to OHAs among clinics ranged from 52.8% to 61.9% (interquartile range = 57.9% to 59.4%). In multivariate analysis, organizational features associated with higher clinic-level adherence included access to routine care (standardized beta [Sβ] = .21, P = .004), having a respectful office staff (Sβ = 0.21, P = .002), and utilization of telephone encounters (Sβ = 0.23, P < .001). Among a national cohort of veterans with diabetes, overall PCMH implementation did not significantly increase adherence to oral hypoglycemic agents, although aspects of implementation were associated with increased adherence. Measures of access to care appear the most significant.

Introduction Endothelin-1 (ET-1) is a potent vasoconstrictive peptide with multi functional activity in various systemic diseases. Previous studies indicate the detection of ET-1 in gingival tissues and gingival crevicular fluid. Aim The aim of this study was to estimate the serum ET-1 levels in clinically healthy subjects and subjects with chronic periodontitis, before and after treatment, and correlate it with the clinical parameters. Materials and Methods A total of 44 patients were included in the study. Group I comprised of 20 subjects with clinically healthy periodontium. Group II comprised of 24 subjects with chronic periodontitis. Group III comprised of same Group II subjects following periodontal management. Serum samples were collected from the subjects and an Enzyme Linked Immunosorbent Assay (ELISA) was done to estimate the ET-1 levels. The ET-1 levels were then correlated among the three groups with the clinical parameters namely, Plaque Index (PI), Sulcus Bleeding Index (SBI), probing pocket depth, clinical attachment loss and Periodontally Inflamed Surface Area (PISA). The independent t-test and paired t-test were used for comparison of clinical parameters and Pearson’s correlation coefficient test was used for correlating the ET-1 levels. Results ET-1 levels in chronic periodontitis subjects were significantly higher compared to healthy subjects (p<0.001). However, the clinical parameters did not statistically correlate with the ET-1 levels. There was a significant decrease in ET-1 levels following treatment (p<0.001). Conclusion Serum ET-1 is increased in chronic periodontitis and reduces after periodontal therapy. Further studies are required to establish ET-1 as a biomarker for periodontal disease.

The relations of fear to anxiety sensitivity, control beliefs, and maternal overprotection were examined in 126 7- to 13-year-old clinically referred children with specific phobias. Results indicated that anxiety sensitivity and control beliefs were significant predictors of children’s fear levels, accounting for approximately 48% of the total variance. Unexpectedly, age, gender, and maternal overprotection did not emerge as significant predictors of fear in the overall sample. In subsequent analyses, anxiety sensitivity was found to be a consistent, significant predictor for both girls and boys, for both younger and older children, and for children with and without an additional anxiety disorder diagnosis. Control beliefs were only a significant predictor for girls, younger children, and children with an additional anxiety diagnosis. Maternal overprotection was not a significant predictor for any group. Children with an additional anxiety disorder diagnosis had higher levels of fear, anxiety sensitivity, and maternal overprotection, as well as lower levels of control beliefs than the non-additional anxiety disorder subgroup. Future directions and clinical implications are explored. PMID:26273182

Orthopaedic sports medicine practices utilize a variety of healthcare professionals to assist physicians in the clinic. The purpose of this study was to investigate patients' perception of orthopaedic knowledge and clinical care provided by orthopaedic medical residents and athletic trainers (ATs). ATs will be perceived similarly to orthopaedic medical residents in overall patient care and perceived education level. Randomized, double-blind survey. 2. New patients were randomly selected to receive the survey to complete during an office visit. The survey included 8 questions which rated the patient's perceived level of orthopaedic knowledge and level of patient care provided by the AT and orthopaedic medical residents. A total of 110 surveys were collected during the 2-year study period. The data were analyzed using a multivariate analysis of variance (MANOVA). The multivariate effect (Pillai's trace) was not significant between clinicians, F(8,111)=0.122, p=0.695, partial η2=0.106. Univariate tests showed a significance between patient perceived level of clinician education, F(1,118)=5.361, p=0.632, partial η2=0.043. Univariate test showed no significant differences on any other dependent variables. There is no evidence that patients' perception is different when comparing ATs and orthopaedic medical residents in orthopaedic knowledge and clinical care. Although a statistically significant difference was found in the perceived highest level of education attained, orthopaedic medical residents and ATs were each perceived to have a master's degree level of education. Physicians should continue to use ATs in their practices.

To examine the relationships between critical thinking ability and nursing competence in clinical nurses. There are few evidance-based data related to the relationship between critical thinking ability and nursing competence of clinical nurses. A cross-sectional and correlation research design was used. A total of 570 clinical nurses at a medical centre in southern Taiwan were recruited into this study. Two self-report questionnaires, the Watson-Glaser Critical Thinking Appraisal (WGCTA) and the Nursing Competence Scale (NCS), were used to collect data. The critical thinking ability of clinical nurses was at the middle level. The highest score for the subscales of the WGCTA was 'interpretation ability' and the lowest was 'inference ability'. The nursing competence of clinical nurses was at the middle level and above. The highest score for the subscales was 'caring ability' and the lowest was 'research ability'. Critical thinking ability had a significantly positive correlation with nursing competence. Critical thinking, working years, educational levels and position/title were the significant predictors of nursing competence, accounting for 32·9% of the variance. Critical thinking ability had a significantly positive correlation with nursing competence. The critical thinking ability of clinical nurses with a master's degree was significantly better than those with a bachelor's degree or a diploma and nurses with over five working years was significantly better than those with under five years. The findings of this study can further serve as a reference for nursing education to improve nursing curricula and teaching strategies for nurse preparation. It could also be a guideline for nursing administration personnel in on-the-job training and orientation programs for nursing staff. © 2011 Blackwell Publishing Ltd.

Endometritis significantly impacts fertility and milk yield, thus reducing profitability of the dairy production. In cows that develop endometritis, normal postpartum endometrial inflammation is dysregulated. Here, we propose that endometrial inflammation is reflected in cervico-vaginal mucus (CVM) which could therefore be used as a prognostic tool. CVM was collected from 20 dairy cows (10 with clinical endometritis and 10 healthy) 7 and 21 days postpartum (DPP). Polymorphonuclear (PMN), mononuclear leukocyte and epithelial cells were counted, total protein levels were estimated and levels of IL-1β, IL-6, IL-8, serum amyloid A (SAA), haptoglobin (Hp) and C5b were analyzed by ELISA in CVM. PMN were consistently high in CVM from 7 to 21 DPP, but were higher in CVM from cows with clinical endometritis 21 DPP compared with healthy cows. In contrast, there were more epithelial cells in healthy cows 21 DPP than in clinical endometritis animals. Total protein levels decreased significantly in CVM from healthy cows between days 7 and 21 postpartum. All inflammatory biomarkers except C5b, remained high in cows with clinical endometritis from 7 to 21 DPP, indicating sustained and chronic endometrial inflammation. IL1, IL-6, IL-8 and Hp levels were higher in CVM from cows with clinical endometritis compared to healthy cows 21 DPP. Interestingly IL-1β levels were raised in CVM from clinical endometritis but not in healthy cows 7 DPP suggesting that early measurement of IL-1β levels might provide a useful predictive marker of clinical endometritis. In contrast, SAA and C5b levels were increased in healthy cows 21 DPP, compared to cows with clinical endometritis suggesting that these acute phase proteins might have an anti-inflammatory role. Our results show that CVM is convenient for profiling disease-associated changes in key inflammatory molecules postpartum and reaffirms that sustained inflammation is a key feature of clinical endometritis in the dairy cow.

To study the clinical significance of determination of serum B7-H4 in patients with malignant hematologic diseases. Serum B7-H4 levels were determined in 65 patients with leucemia, 34 patients with lymphoma, 12 patients with multiple myeloma as well as in 50 healthy controls. The serum B7-H4 levels in patients with lymphoma [(38.81+/-10.34) kappag/L] were significantly higher than healthy controls [(31.62+/-9.850) kappag/L] (P<0.01). But there are no significant difference of B7-H4 levels in serum among patients with leucemia, patients with multiple myeloma and healthy controls. These results suggest that the B7-H4 may correlated with lymphoma, but uncorrelated with leucemia and multiple myeloma. Measurement of serum B7-H4 level provide useful information for distinctive diagnosis of different kinds of malignant hematologic diseases.

To describe clinical characteristics of fibromyalgia in an Australian population. Data was collected from 150 consecutive patients with clinical features of fibromyalgia seen in an Australian public hospital clinic. Demographic information and clinical characteristics were recorded. Significant correlations between clinical characteristics were identified, then used in multiple regression analyses to identify factors influencing outcome in physical function, pain, fatigue and sleep disturbance. Clinical features in groups who were or were not using different treatment strategies were compared. Most patients were female and Caucasian. The majority reported a recognizable trigger factor and many had associated conditions, most commonly headache and irritable bowel syndrome. Physical function was significantly accounted for by pain levels (P = 0.001); pain score was significantly predicted by tenderness (P = 0.002) and physical function level (P = 0.001); fatigue levels were significantly influenced by age (P = 0.007) and sleep disturbance (P < 0.001), and sleep disturbance was significantly predicted by fatigue (P < 0.001). Just over one-third (34%) of patients were using fibromyalgia medications (low-dose tricyclic antidepressant, pregabalin or duloxetine); however, they had less anxiety (P = 0.006) and better reported physical function (P = 0.04) than those who were not. Less than half (43.6%) of the patients were regularly exercising; however, they had reduced overall illness impact scores (P = 0.004), better physical function (P = 0.01) and less fatigue (P = 0.03), anxiety (P = 0.02) and depressive features (P = 0.008) than non-exercisers. Baseline clinical characteristics in this group were comparable to other study populations. The use of management modalities with proven benefit in fibromyalgia was limited; however, those patients who were engaged in regular exercise or using medication had better self-reported outcome measures than those who were not. © 2012 The Authors International Journal of Rheumatic Diseases © 2012 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

Decoy receptor 3 (DcR3) is associated with autoimmunity and altered angiogenesis in certain pathological conditions. We herein measured serum DcR3 levels in 51 patients with systemic sclerosis (SSc) and 19 healthy controls and evaluated their clinical significance in this disorder. Serum DcR3 levels were significantly higher in diffuse cutaneous SSc (dcSSc) patients than in limited cutaneous SSc patients and in healthy controls. In dcSSc, serum DcR3 levels were significantly elevated in patients with disease duration of ≤6 years compared with healthy controls, but not in those with disease duration of >6 years. Serum DcR3 levels correlated negatively with the percentage of predicted diffusion lung capacity for carbon monoxide and positively with right ventricular systolic pressure. Furthermore, serum DcR3 levels positively correlated with C-reactive protein, erythrocyte sedimentation rate and immunoglobulin G. Collectively, the elevation of serum DcR3 levels is associated with the development of pulmonary arterial hypertension and systemic inflammation in SSc.

Three exposure categories (''exposed'', ''nominally exposed'', ''nonexposed'') were defined. Complete work histories, clinical histories, physical examinations and laboratory tests, including plasma PCB determinations were obtained. In addition, fat PCB levels were determined in randomly selected subjects in each exposed group. Evidence of dermatotoxicity was observed and elevated PCB levels were noted more frequently in the exposed group (p < .00001), correlating well with age and duration of employment. Thesemore » correlations were stronger for fat (p < .001) than for plasma (p < .01) PCB levels.

These correlations remained significant after controlling for either age or length of employment. No significant correlations were found between PCB levels and levels of cholesterol, high-density lipoprotein cholesterol or levels studied on liver function tests other than SGOT. Further analyses relating frequency of reported direct contact with PCB levels suggested a dermal route of exposure.

Inconsistent findings concerning brain-derived neurotrophic factor (BDNF) levels across different episodes in bipolar disorder have been reported, which is also in line with the treatment effects on BDNF levels in acute mania. We aimed to compare plasma BDNF level alterations after pure antipsychotic drug or ECT plus antipsychotic drug treatment in acute mania. Sixty-eight patients with mania were divided into two treatment arms: the antipsychotic treatment arm (AP) and electroconvulsive therapy (ECT)+AP arm. In addition, 30 healthy controls were included in the study. There was no significant statistical difference according to mean age, education level, marital and working status between patients and healthy controls. The initial serum BDNF level in patients with acute mania was significantly lower than healthy controls. The initial BDNF level between the ECT arm and AP arm was not significant. The BDNF level decreased significantly after reaching remission in patients with acute mania. The change in BDNF level in the AP arm was not significant while in the ECT arm it was significant after treatment. In this study, for the first time we revealed a significant decrease in BDNF levels after ECT sessions in acute manic patients. Besides clinical remission after treatment in acute mania, the decrement in BDNF levels does not seem to be related to clinical response. Thus cumulative effects of mood episodes for the ongoing decrease in BDNF levels might be borne in mind despite the achievement of remission and/or more time being required for an increase in BDNF levels after treatment. © The Author(s) 2015.

This study investigated the impact of early enteral nutrition (EEN) on the clinical outcomes of gastric cancer patients after radical gastrectomy. Four hundred gastric cancer patients undergoing radical gastrectomy of any extend with D2 nodal dissection were randomly divided into an experimental and a control group with 200 cases in each group. Patients in the control group received postoperative parenteral nutrition (PN), while patients in the experimental group received postoperative EEN. After treatment, the clinical outcomes, postoperative immune function, and nutritional status of the two groups were evaluated. The postoperative fever time, intestinal function recovery time, anal exhaust time, and the length of hospital stay for patients in the experimental group were significantly shorter than those of the control group. We did not find significant differences in anastomotic leak, postoperative ileus and regurgitation between the two groups. The activities of multiple immune cell types, including CD3⁺, CD4⁺, CD4⁺/CD8⁺, and natural killer (NK) cells, were significantly lower in both groups on postoperative day 1 when compared with the preoperative levels (p<0.05). The level of CD8⁺ was not significantly different between the two groups (p>0.05). After treatment, levels of CD3⁺, CD4⁺, CD4⁺/CD8⁺, and NK cells in the experimental group patients were 35.6 ± 4.2, 42.2 ± 3.0, 1.7 ± 0.3, and 27.3 ± 5.3%, respectively, on postoperative day 7, which were similar to the preoperative levels. The immune cell levels from the control group patients remained significantly lower when compared with preoperative values; in addition, these values were also significantly lower when compared with the EEN patients (p<0.05) CONCLUSION: For gastric cancer patients undergoing radical gastrectomy, the clinical outcome, immune function and nutritional status after EEN were significantly improved. These data suggest the widespread use of EEN in clinical practice.

To evaluate the correlation between clinical and salivary microbial parameters during treatment with removable orthodontic appliances with or without use of fluoride mouth rinse. A group of 48 patients completed this randomized, controlled, parallel-group, clinical pilot study. 24 patients of the test group (TG) rinsed after tooth brushing with a fluoride mouth rinse (100 ppm AmF/150 ppm NaF) while 21 patients of the control group (CG) did not. Clinical parameters [Approximal Plaque Index (API), Papillary Bleeding Index (PBI)] as well as levels of salivary mutans streptococci (MS) and lactobacilli (LB) were assessed at baseline and after 3, 6, 9 and 12 months. Compliance was documented by participants. Appliance wear-times were estimated retrospectively by the patients. All participants received the same brushing instructions and were supplied with the same toothbrush/toothpaste. A significant correlation of API values with MS levels (p=0.0003) or with LB levels (p=0.001) was observed. Furthermore, appliance wear-times were significantly associated with API values (p=0.02). The changes of MS or LB levels between beginning and end of the study did not differ significantly between study groups. The changes of the API scores showed slightly different median values (-3.5 in the TG vs. 0 in the CG), the difference, however, was not significant. The results emphasise the need for a careful monitoring of the oral hygiene status in patients with removable orthodontic appliances. Larger controlled clinical trials are necessary to investigate treatment options such as use of supplementary fluoride mouth rinse.

To conduct a preliminary study comparing different trauma and clinical populations on types of shame coping style and levels of state shame and guilt. A mixed independent groups/correlational design was employed. Participants were recruited by convenience sampling of 3 clinical populations-complex trauma (n = 65), dissociative identity disorder (DID; n = 20), and general mental health (n = 41)-and a control group of healthy volunteers (n = 125). All participants were given (a) the Compass of Shame Scale, which measures the four common shame coping behaviors/styles of "withdrawal," "attack self," "attack other," and "avoidance," and (b) the State Shame and Guilt Scale, which assesses state shame, guilt, and pride. The DID group exhibited significantly higher levels of "attack self," "withdrawal," and "avoidance" relative to the other groups. The complex trauma and general mental health groups did not differ on any shame variable. All three clinical groups had significantly greater levels of the "withdrawal" coping style and significantly impaired shame/guilt/pride relative to the healthy volunteers. "Attack self" emerged as a significant predictor of increased state shame in the complex trauma, general mental health, and healthy volunteer groups, whereas "withdrawal" was the sole predictor of state shame in the DID group. DID emerged as having a different profile of shame processes compared to the other clinical groups, whereas the complex trauma and general mental health groups had comparable shame levels and variable relationships. These differential profiles of shame coping and state shame are discussed with reference to assessment and treatment. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Serum transthyretin (TTR) levels are reduced in familial amyloidotic polyneuropathy (FAP). A single study of patients with senile systemic amyloidosis (SSA) in Sweden found that those individuals also had a significantly lower mean serum TTR concentration than age- and gender-matched controls. To determine if the same phenomenon prevailed in an ethnically more heterogeneous population, we compared the serum TTR levels, as determined by ELISA, in 45 documented SSA patients with congestive heart failure, 20 AL patients with congestive heart failure and population controls. Serum TTR concentrations in the controls were influenced in a statistically significant manner by age, gender and ethnicity. Although it is unlikely that such differences are clinically relevant, they must be considered when assessing the meaning of serum TTR concentrations in any clinically defined population. The serum concentrations in patients with SSA did not differ from age, gender and ethnically matched controls or from a group of AL patients with significant clinical cardiac involvement. We also compared TTR concentrations in 12 African-Americans carrying the TTR V122I allele with those in 826 African-Americans who were homozygous wild type at the TTR locus. The TTR V122I carriers had significantly lower serum TTR concentrations than appropriate controls even though the majority of such individuals had not reached the age of clinical or anatomic risk, i.e. over 60. Thus, as in carriers of other TTR mutations the serum TTR level is lower than normal, despite having a much later appearance of clinical disease. PMID:19065297

Gallium 67 citrate scans and serum angiotension converting enzyme (ACE) levels were obtained in 54 patients with sarcoidosis and analyzed in relation to clinical manifestation. /sup 67/Ga scans were abnormal in 97% of patients with clinically active disease (n = 30) and in 71% of patients with inactive disease (n = 24). Serum ACE levels were abnormally high (2 standard deviations above the control mean) in 73% of patients with clinically active disease and in 54% of patients with inactive disease. Serum ACE levels correlated significantly with /sup 67/Ga uptake score (r = .436; p < .005). The frequency ofmore » abnormal /sup 67/Ga scans and elevated serum ACE levels suggests that inflammatory activity with little or no clinical expression is common in sarcoidosis. Abnormal /sup 67/Ga scans were highly sensitive (97%) but had poor specificity (29%) to clinical disease activity. The accuracy of negative prediction of clinical activity by normal scans (87%) was better than the accuracy of positive prediction of clinical activity by abnormal scans (63%). /sup 67/Ga scans can be used to support the clinical identification of inactive sarcoidosis.« less

Introduction: HJURP (Holliday Junction Recognition Protein) is a newly discovered gene reported to function at centromeres and to interact with CENPA. However its role in tumor development remains largely unknown. The goal of this study was to investigate the clinical significance of HJURP in breast cancer and its correlation with radiotherapeutic outcome. Methods: We measured HJURP expression level in human breast cancer cell lines and primary breast cancers by Western blot and/or by Affymetrix Microarray; and determined its associations with clinical variables using standard statistical methods. Validation was performed with the use of published microarray data. We assessed cell growthmore » and apoptosis of breast cancer cells after radiation using high-content image analysis. Results: HJURP was expressed at higher level in breast cancer than in normal breast tissue. HJURP mRNA levels were significantly associated with estrogen receptor (ER), progesterone receptor (PR), Scarff-Bloom-Richardson (SBR) grade, age and Ki67 proliferation indices, but not with pathologic stage, ERBB2, tumor size, or lymph node status. Higher HJURP mRNA levels significantly decreased disease-free and overall survival. HJURP mRNA levels predicted the prognosis better than Ki67 proliferation indices. In a multivariate Cox proportional-hazard regression, including clinical variables as covariates, HJURP mRNA levels remained an independent prognostic factor for disease-free and overall survival. In addition HJURP mRNA levels were an independent prognostic factor over molecular subtypes (normal like, luminal, Erbb2 and basal). Poor clinical outcomes among patients with high HJURP expression werevalidated in five additional breast cancer cohorts. Furthermore, the patients with high HJURP levels were much more sensitive to radiotherapy. In vitro studies in breast cancer cell lines showed that cells with high HJURP levels were more sensitive to radiation treatment and had a higher rate of apoptosis than those with low levels. Knock down of HJURP in human breast cancer cells using shRNA reduced the sensitivity to radiation treatment. HJURP mRNA levels were significantly correlated with CENPA mRNA levels. Conclusions: HJURP mRNA level is a prognostic factor for disease-free and overall survival in patients with breast cancer and is a predictive biomarker for sensitivity to radiotherapy.« less

OBJECTIVE Cervical total disc replacement (TDR) has been shown in a number of prospective clinical studies to be a viable treatment alternative to anterior cervical discectomy and fusion (ACDF) for the treatment of symptomatic degenerative disc disease. In addition to preserving motion, evidence suggests that cervical TDR may result in a lower incidence of subsequent surgical intervention than treatment with fusion. The goal of this study was to evaluate subsequent surgery rates up to 5 years in patients treated with TDR or ACDF at 1 or 2 contiguous levels between C-3 and C-7. METHODS This was a prospective, multicenter, randomized, unblinded clinical trial. Patients with symptomatic degenerative disc disease were enrolled to receive 1- or 2-level treatment with either TDR as the investigational device or ACDF as the control treatment. There were 260 patients in the 1-level study (179 TDR and 81 ACDF patients) and 339 patients in the 2-level study (234 TDR and 105 ACDF patients). RESULTS At 5 years, the occurrence of subsequent surgical intervention was significantly higher among ACDF patients for 1-level (TDR, 4.5% [8/179]; ACDF, 17.3% [14/81]; p = 0.0012) and 2-level (TDR, 7.3% [17/234]; ACDF, 21.0% [22/105], p = 0.0007) treatment. The TDR group demonstrated significantly fewer index- and adjacent-level subsequent surgeries in both the 1- and 2-level cohorts. CONCLUSIONS Five-year results showed treatment with cervical TDR to result in a significantly lower rate of subsequent surgical intervention than treatment with ACDF for both 1 and 2 levels of treatment.

Clinical training has been recognized as a stressful experience for nursing students. The aims of this study were to identify levels and types of stressors among nursing students during their clinical training and their coping behaviors. Data were collected using a purposive sampling method from 100 nursing students using a self-reported questionnaire composed of Perceived Stress Scale and Coping Behavior Inventory. Results showed that "assignments and workload" as well as "teachers and nursing staff" were the highest sources of stress in clinical training. The most common coping behaviors used were "problem-solving" and "staying optimistic". There was a significant difference in perceived stress among students in regard to the way of choosing nursing. There were significant differences in coping behaviors in regard to the presence of relatives in nursing, living status and mothers' educational level. The predictors of perceived stress were self-choosing for nursing and the presence of relatives in nursing, while the predictors for coping behaviors were stress from peers and daily life as well as mothers' educational level. Nursing teachers and staff are encouraged to develop strategies that decrease level of stress and promote adaptive coping behaviors among nursing students during their clinical training.

Food formulation with bioactive ingredients is a potential strategy to promote satiety and weight management. Whey proteins are high in leucine and are shown to decrease hunger ratings and increase satiety hormone levels; cocoa polyphenolics moderate glucose levels and slow digestion. This study examined the effects of cocoa and whey proteins on lipid and glucose metabolism and satiety in vitro and in a clinical trial. In vitro, 3T3-L1 preadipocytes were treated with 0.5-100 μg/mL cocoa polyphenolic extract (CPE) and/or 1-15 mM leucine (Leu) and assayed for lipid accumulation and leptin production. In vivo, a 6-week clinical trial consisted of nine panelists (age: 22.6 ± 1.7; BMI: 22.3 ± 2.1) consuming chocolate-protein beverages once per week, including placebo, whey protein isolate (WPI), low polyphenolic cocoa (LP), high polyphenolic cocoa (HP), LP-WPI, and HP-WPI. Measurements included blood glucose and adiponectin levels, and hunger ratings at baseline and 0.5-4.0 h following beverage consumption. At levels of 50 and 100 μg/mL, CPE significantly inhibited preadipocyte lipid accumulation by 35% and 50%, respectively, and by 22% and 36% when combined with 15 mM Leu. Leu treatment increased adipocyte leptin production by 26-37%. In the clinical trial, all beverages significantly moderated blood glucose levels 30 min postconsumption. WPI beverages elicited lowest peak glucose levels and HP levels were significantly lower than LP. The WPI and HP beverage treatments significantly increased adiponectin levels, but elicited no significant changes in hunger ratings. These trends suggest that combinations of WPI and cocoa polyphenols may improve markers of metabolic syndrome and satiety.

In patients who have had type 1 diabetes for 5 years, current recommendations regarding screening for diabetic retinopathy include annual dilated retinal examinations to detect proliferative retinopathy or clinically significant macular edema, both of which require timely intervention to preserve vision. During 30 years of the Diabetes Control and Complications Trial (DCCT) and its longitudinal follow-up Epidemiology of Diabetes Interventions and Complications (EDIC) study, retinal photography was performed at intervals of 6 months to 4 years. We used retinal photographs from the DCCT/EDIC study to develop a rational screening frequency for retinopathy. Markov modeling was used to determine the likelihood of progression to proliferative diabetic retinopathy or clinically significant macular edema in patients with various initial retinopathy levels (no retinopathy or mild, moderate, or severe nonproliferative diabetic retinopathy). The models included recognized risk factors for progression of retinopathy. Overall, the probability of progression to proliferative diabetic retinopathy or clinically significant macular edema was limited to approximately 5% between retinal screening examinations at 4 years among patients who had no retinopathy, 3 years among those with mild retinopathy, 6 months among those with moderate retinopathy, and 3 months among those with severe nonproliferative diabetic retinopathy. The risk of progression was also closely related to mean glycated hemoglobin levels. The risk of progression from no retinopathy to proliferative diabetic retinopathy or clinically significant macular edema was 1.0% over 5 years among patients with a glycated hemoglobin level of 6%, as compared with 4.3% over 3 years among patients with a glycated hemoglobin level of 10%. Over a 20-year period, the frequency of eye examinations was 58% lower with our practical, evidence-based schedule than with routine annual examinations, which resulted in substantial cost savings. Our model for establishing an individualized schedule for retinopathy screening on the basis of the patient's current state of retinopathy and glycated hemoglobin level reduced the frequency of eye examinations without delaying the diagnosis of clinically significant disease.

To assess the utility of measuring lung surfactant protein A (SP-A) in serum, a newly developed SP-A kit (Teijin TDR-30) was used at four facilities to measure serum SP-A levels in patients with various lung diseases. Serum SP-A levels in healthy volunteers were 24.6 +/- 9.6 ng/ml (mean +/- SD). serum SP-A levels did not differ significantly between different age groups (thirties through seventies). A cut-off level of 43.8 ng/ml was calculated, based on the values of the healthy volunteers. The serum SP-A levels in patients with idiopathic interstitial pneumonia (IIP: 67.9 +/- 42.5 ng/ml), pulmonary alveolar proteinosis (PAP: 7.0 +/- 45.7 ng/ml), and collagen disease with interstitial pneumonia (CDIP: 55.3 +/- 37.9 ng/ml) were significantly higher than those in healthy volunteers. When calculated with the cut-off value stated above, the positive rate of diagnosis for IIP was 71.4%. SP-A levels correlated closely with the clinical course; SP-A levels rose significantly during exacerbations of IIP. Measurement of SP-A in serum is useful for the diagnosis of IIP, PAP, and CDIP, and for monitoring exacerbations of IIP.

In the context of an educational program on schizophrenia for psychiatry trainees, this survey study analyzed associations between self-reported training adequacy, experience in providing patient care, and comfort level in performing schizophrenia-related clinical skills. The influence of the education on comfort level was also assessed for each skill. Survey respondents were psychiatry residents and fellows who participated in a schizophrenia education program at an in-person workshop or through online videos recorded at the workshop. In a pre-program survey, participants reported their experience in providing schizophrenia patient care and rated their training adequacy and comfort level for performing seven clinical skills involved in diagnosing and treating schizophrenia. The post-program survey included items for reassessing comfort level in performing the skills. Across the seven clinical skills, the proportion of respondents (n = 79) who agreed or strongly agreed that their training was adequate ranged from 29 to 88 %. The proportion of high ratings for comfort level in skill performance ranged from 45 to 83 %. Comfort level was significantly associated with training adequacy for all seven clinical skills and with experience in providing patient care for four skills. For all skills, comfort level ratings were significantly higher after versus before the educational workshop. Commonly indicated needs for further training included education on new therapies, exposure to a broader range of patients, and opportunities for longitudinal patient management. Psychiatry trainees' self-reported, disease-specific training adequacy, experiences, and comfort level have unique applications for developing and evaluating graduate medical curriculum.

To review and critically assess trends observed regarding the levels of evidence in published articles in orthopaedic traumatology literature. The Journal of Orthopaedic Trauma, Journal of Bone and Joint Surgery-American, and Clinical Orthopaedics and Related Research. All articles from the years 1998, 2003, 2008, and 2013 in The Journal of Orthopaedic Trauma (JOT) and orthopaedic trauma-related articles from The Journal of Bone and Joint Surgery-American (JBJS-A) and Clinical Orthopaedics and Related Research (CORR) were analyzed. Articles were categorized by type and ranked for level of evidence according to guidelines from the Centre for Evidence-Based Medicine. Study type and standardized level of evidence were determined for each article. Articles were subcategorized as high-level evidence (I, II), moderate-level evidence (III), and low-level evidence (IV, V). During the study period, Journal of Bone and Joint Surgery-American reduced its low-level studies from 80% to 40% (P = 0.00015), Clinical Orthopaedics and Related Research decreased its low-level studies from 70% to 27%, and Journal of Orthopaedic Trauma decreased its low-level studies from 78% to 45%. Level IV and V therapeutic, prognostic, and diagnostic studies demonstrated significant decreases during the study period (P = 0.0046, P < 0.0001, P = 0.026). The percentage of high-level studies increased from 13% to 19%; however, this was not significant (P = 0.42). There was a trend showing an increase in level I and II studies for therapeutic, prognostic, and diagnostic studies (P = 0.06). There has been a statistically significant decrease in lower level of evidence studies published in the orthopaedic traumatology literature over the past 15 years.

Objectives To identify clinical, functional and health-related quality of life (HRQoL) correlates of clinically significant symptoms of anxiety and depression in patients with systemic sclerosis (SSc). Methods Three-hundred-and-eighty-one patients fulfilling the American College of Rheumatology and/or the Leroy and Medsger criteria for SSc were assessed for visceral involvement, disability and HRQoL (assessed by SF-36). Clinically significant symptoms of anxiety and depression were evaluated with the Hospital Anxiety Depression Scale (HAD) (defined cut-off≥8). Results 9.2% the patients had limited SSc, 50.5% limited cutaneous SSc (lcSSc), and 40.3% diffuse cutaneous SSc (dcSSc). Overall, 40.4% and 58.8% of the patients had clinically significant symptoms of depression and anxiety, respectively. Compared to patients without clinically significant symptoms of depression, patients with clinically significant symptoms of depression had poorer health status, HRQoL mental and physical component, and greater global disability, hand disability and aesthetic impairment. Compared to patients without clinically significant symptoms of anxiety, patients with clinically significant symptoms of anxiety had poorer SF-36 mental and physical component scores. On multivariable analysis, excluding mental component score of SF-36, variables independently associated with clinically significant symptoms of depression and anxiety were global disability and physical component of SF-36, plus female gender for clinically significant symptoms of anxiety only. Remarkably, patients with and without clinically significant psychiatric symptoms were comparable for all disease-related clinical features assessed. Conclusion High levels of clinically significant symptoms of anxiety and depression are observed among SSc patients. Clinically significant psychiatric symptoms are rather associated with increased disability and altered HRQoL, than with disease-specific organ manifestations. PMID:24587375

The aim of our study was to investigate the effects of a combined treatment with alpha-lipoic acid (ALA) and myoinositol (MYO) on clinical, endocrine and metabolic features of women affected by polycystic ovary syndrome (PCOS). In this pilot cohort study, forty women with PCOS were enrolled and clinical, hormonal and metabolic parameters were evaluated before and after a six-months combined treatment with ALA and MYO daily. Studied patients experienced a significant increase in the number of cycles in six months (p < 0.01). The free androgen index (FAI), the mean androstenedione and DHEAS levels significantly decreased after treatment (p < 0.05). Mean SHBG levels significantly raised (p < 0.01). A significant improvement in mean Ferriman-Gallwey (F-G) score (p < 0.01) and a significant reduction of BMI (p < 0.01) were also observed. A significant reduction of AMH levels, ovarian volume and total antral follicular count were observed in our studied women (p< 0.05). No significant changes occurred in gluco-insulinaemic and lipid parameters after treatment. The combined treatment of ALA and MYO is able to restore the menstrual pattern and to improve the hormonal milieu of PCOS women, even in the absence of apparent changes in insulin metabolism.

Cervical total disc replacement (TDR) is an increasingly accepted procedure for the treatment of symptomatic cervical degenerative disc disease. Multiple Level I evidence clinical trials have established cervical TDR to be a safe and effective procedure in the short-term. The objective of this study is to provide a long-term assessment of TDR versus anterior discectomy and fusion for the treatment of one- and two-level disc disease. This study was a continuation of a prospective, multicenter, randomized, US FDA IDE clinical trial comparing cervical TDR with the Mobi-C © Cervical Disc versus ACDF through 7 years follow-up. Inclusion criteria included a diagnosis of symptomatic cervical degenerative disc disease at one or two cervical levels. TDR patients were treated using a Mobi-C © artificial disc (Zimmer Biomet, Austin TX, USA). ACDF with allograft and anterior plate was used as a control treatment. Outcome measures were collected preoperatively and postoperatively at 6 weeks, at 3, 6, 12, 18 months, annually through 60 months, and at 84 months. Measured outcomes included Overall success, Neck Disability Index (NDI), VAS neck and arm pain, segmental range of motion (ROM), patient satisfaction, SF-12 MCS/PCS, major complications, and subsequent surgery rate. The primary endpoint was an FDA composite definition of success comprising clinical improvement and an absence of major complications and secondary surgery events. A total of 599 patients were enrolled and treated, with 164 treated with one-level TDR, 225 treated with two-level TDR, 81 treated with one-level ACDF, and 105 treated with two-level ACDF. At seven years, follow-up rates ranged from 73.5% to 84.4% (overall 80.2%).The overall success rates of two level TDR and ACDF patients were 60.8% and 34.2%, respectively (p<0.0001). The overall success rates of one level TDR and ACDF patients were 55.2% and 50%, respectively (p>0.05). Both the single and two level TDR and ACDF groups showed significant improvement from baseline NDI scores, VAS neck and arm pain scores, and SF-12 MCS/PCS scores (p<0.0001). In the single level cohort, there was an increased percentage of TDR patients who reported themselves as "very satisfied" (TDR 90.9% vs ACDF 77.8%; p= 0.028). There was a lower rate of adjacent level secondary surgery in the single level TDR patients (3.7%) versus the ACDF patients (13.6%; p = 0.007).In the two level TDR group, the NDI success rate was significantly greater in the TDR group (TDR: 79.0% vs. ACDF: 58.0%; p=0.001). There was significantly more improvement in NDI change score at 7 years in the TDR patients versus ACDF. The TDR group had a significantly higher rate of patients who were "very satisfied" with their treatment compared to the ACDF group (TDR: 85.9% vs. ACDF: 73.9%). The rate of subsequent surgery at the index level was significantly lower in the TDR group compared to the ACDF group (TDR: 4.4% vs. ACDF: 16.2%; p=0.001). The rate of adjacent level secondary surgery was significantly lower in the two level TDR (4.4%) patients compared to the ACDF (11.3%; p=0.03) patients. In both single and two level cohorts, the percentage of patients with worse NDI (2.5%-3.8% of two level surgeries and 1.2%-2.5% of single level surgeries) or worse neck pain (5%-6.8% of the two level surgeries and 1.3% - 3.8% of the single level surgeries) was strikingly low in both groups but trended lower in the TDR patients. At seven years, the composite success analysis demonstrated clinical superiority of two level TDR over ACDF and non-inferiority of single level TDR versus ACDF. There were lower rates of secondary surgery and higher adjacent level disc survivorship in both groups. Both surgeries were remarkably effective in alleviating pain relative to baseline and the rate of patients with worse disability or neck pain was surprisingly low. Overall, greater than 95% of patients (from both groups) who underwent TDR and 88% of patients who underwent ACDF were "very satisfied" at seven years. The differences in clinical effectiveness of TDR versus ACDF becomes more apparent as treatment increases from one to two levels, indicating a significant benefit for TDR over ACDF for two-level procedures. The Mobi-C Clinical Trial (ClinicalTrials.gov registration number: NCT00389597) was conducted at 24 sites in the US and was approved by the Institutional Review Board, Research Ethics Committee, or local equivalent of each participating site. 1.

This study evaluated the effect of physiological, TSH-guided, L-thyroxine treatment on serum lipids and clinical symptoms in patients with subclinical hypothyroidism. Sixty-six women with proven subclinical hypothyroidism (TSH, 11.7 +/- 0.8 mIU/liter) were randomly assigned to receive L-thyroxine or placebo for 48 wk. Individual L-thyroxine replacement (mean dose, 85.5 +/- 4.3 microg/d) was performed based on blinded TSH monitoring, resulting in euthyroid TSH levels (3.1 +/- 0.3 mIU/liter). Lipid concentrations and clinical scores were measured before and after treatment. Sixty-three of 66 patients completed the study. In the L-thyroxine group (n = 31) total cholesterol and low density lipoprotein cholesterol were significantly reduced [-0.24 mmol/liter, 3.8% (P = 0.015) and -0.33 mmol/liter, 8.2% (P = 0.004), respectively]. Low density lipoprotein cholesterol decrease was more pronounced in patients with TSH levels greater than 12 mIU/liter or elevated low density lipoprotein cholesterol levels at baseline. A significant decrease in apolipoprotein B-100 concentrations was observed (P = 0.037), whereas high density lipoprotein cholesterol, triglycerides, apolipoprotein AI, and lipoprotein(a) levels remained unchanged. Two clinical scores assessing symptoms and signs of hypothyroidism (Billewicz and Zulewski scores) improved significantly (P = 0.02). This is the first double blind study to show that physiological L-thyroxine replacement in patients with subclinical hypothyroidism has a beneficial effect on low density lipoprotein cholesterol levels and clinical symptoms of hypothyroidism. An important risk reduction of cardiovascular mortality of 9-31% can be estimated from the observed improvement in low density lipoprotein cholesterol.

The educative models and strategies to achieve a significant learning have a wide variety. The development of clinical aptitude for clinical research papers lecture has an important place to maintain the physician actualized and for resident formation. To evaluate the degree of development of the aptitude for the reading of clinical research articles in 2nd grade residents of the gynecology and obstetrics speciality alter an educative strategy. In 16 2nd year gynecology and obstetrics residents, a previously validated instrument was applied for the evaluation of critical lecture of clinical research articles in general medicine previous and after and educative strategy. Statistical analysis was with Kruskal-Wallis analysis of variance. Also Wilcoxon test was used to assess the differences between baseline and final results. The median of age was 27 (24-31) years, gender 56.3% women and 43.8% men. A statistically significant increase in global score was observed after the educative strategy. After it only there was a significant increase in the indicator to interpret. After evaluating the domain degrees according to the indicator to interpret, in baseline evaluation it predominated the very low level and at the final evaluation the very low and low levels. In the indicator to judge at baseline the majority were in the very low level, and at the end in very low and low levels. According to the indicator to propose at baseline all were in the level expected by hazard, and at the end a minimal proportion was at very low level. These results traduce a discrete improvement in critical lecture process, which makes to consider the educative strategy that was used, since the objective to improve critical lecture capacity was not achieved.

Background. Transferrin is a negative acute phase protein, which decreases during inflammation and infection. The aim of the present investigation was to evaluate changes in the transferrin serum levels subsequent to non-surgical treatment of chronic periodontal disease. Methods. Twenty patients with chronic periodontitis and 20 systemically healthy subjects without periodontal disease, who had referred to Tabriz Faculty of Dentistry, were selected. Transferrin serum levels and clinical periodontal parameters (pocket depth, clinical attachment level, gingival index, bleeding index and plaque index) were measured at baseline and 3 months after non-surgical periodontal treatment. Data were analyzed with descriptive statistical methods (means ± standard deviations). Independent samples t-test was used to compare transferrin serum levels and clinical variables between the test and control groups. Paired samples t-test was used in the test group for comparisons before and after treatment. Statistical significance was set at P < 0.05. Results. The mean transferrin serum level in patients with chronic periodontitis (213.1 ± 9.2 mg/dL) was significantly less than that in periodontally healthy subjects (307.8 ± 11.7 mg/dL). Three months after periodontal treatment, the transferrin serum level increased significantly (298.3 ± 7.6 mg/dL) and approached the levels in periodontally healthy subjects (P < 0.05). Conclusion. The decrease and increase in transferrin serum levels with periodontal disease and periodontal treatment, respectively, indicated an inverse relationship between transferrin serum levels and chronic periodontitis.

We investigated the treatment effects of a home-based rehabilitation program compared with clinic-based rehabilitation in patients with stroke. A single-blinded, 2-sequence, 2-period, crossover-designed study. Rehabilitation clinics and participant's home environment. Individuals with disabilities poststroke. During each intervention period, each participant received 12 training sessions, with a 4-week washout phase between the 2 periods. Participants were randomly allocated to home-based rehabilitation first or clinic-based rehabilitation first. Intervention protocols included mirror therapy and task-specific training. Outcome measures were selected based on the International Classification of Functioning, Disability and Health. Outcomes of impairment level were the Fugl-Meyer Assessment, Box and Block Test, and Revised Nottingham Sensory Assessment. Outcomes of activity and participation levels included the Motor Activity Log, 10-meter walk test, sit-to-stand test, Canadian Occupational Performance Measure, and EuroQoL-5D Questionnaire. Pretest analyses showed no significant evidence of carryover effect. Home-based rehabilitation resulted in significantly greater improvements on the Motor Activity Log amount of use subscale (P=.01) and the sit-to-stand test (P=.03) than clinic-based rehabilitation. The clinic-based rehabilitation group had better benefits on the health index measured by the EuroQoL-5D Questionnaire (P=.02) than the home-based rehabilitation group. Differences between the 2 groups on the other outcomes were not statistically significant. The home-based and clinic-based rehabilitation groups had comparable benefits in the outcomes of impairment level but showed differential effects in the outcomes of activity and participation levels.

Anti-inflammatory cytokines play a crucial role in periodontitis by inhibiting synthesis of pro-inflammatory cytokines. The purpose of this study was to evaluate the effect of interleukin-10 (-597) gene polymorphism and genotype distributions on chronic periodontitis (CP) development and IL-6 and IL-10 levels in gingival crevicular fluid (GCF) and serum before and after non-surgical periodontal treatment. The study population consisted of 55 severe generalized CP patients as CP group and 50 healthy individuals as control group. Plaque index, gingival index, probing depth and clinical attachment level were recorded and GCF and blood samples were taken at both the baseline and the sixth week after non-surgical periodontal treatment. PCR-RFLP procedure was used for gene analyses and cytokine levels were measured via ELISA. IL-10 genotype distribution was significantly different between CP and control groups (p=0.000, OR:7, 95%CI, 2.83-60.25). Clinical measurements significantly improved in the CP group after periodontal treatment (p<0.05). Periodontal treatment significantly decreased GCF IL-6 and IL-10 levels. No significant difference was found in clinical parameters between IL-10 AA and AC+CC genotypes at both the baseline and the sixth week (p>0.05). Sixth week GCF IL-10 levels were significantly lower in patients carrying IL-10 AC+CC genotype compared to the patients carrying IL-10 AA genotype (p<0.05). Serum IL-6 and IL-10 levels were lower in patients carrying the IL-10 AA genotype compared to patients with IL-10 AC+CC genotype, but the difference was not significant (p>0.05). IL-10 AA genotype carriers had lower IL-6 and IL-6/10 levels in serum; however, GCF IL-6/10 levels were similar in both genotypes. Within the limitations of our study, a possible association between IL-10(-597) gene polymorphism and CP might be considered.

The purpose of this study was to determine if there is an association between admission interview score and subsequent academic and clinical performance, in a four-year undergraduate physiotherapy course. Retrospective observational study. 141 physiotherapy students enrolled in two entry year groups. Individual student performance in all course units, practical examinations, clinical placements as well as year level and overall Grade Point Average. Predictor variables included admission interview scores, admission academic scores and demographic data (gender, age and entry level). Interview score demonstrated a significant association with performance in three of six clinical placements through the course. This association was stronger than for any other admission criterion although effect sizes were small to moderate. Further, it was the only admission score to have a significant association with overall Clinical Grade Point Average for the two year groups analysed (r=0.322). By contrast, academic scores on entry showed significant associations with all year level Grade Point Averages except Year 4, the clinical year. This is the first study to review the predictive validity of an admission interview for entry into a physiotherapy course in Australia. The results show that performance in this admission interview is associated with overall performance in clinical placements through the course, while academic admission scoring is not. These findings suggest that there is a role for both academic and non-academic selection processes for entry into physiotherapy. Copyright © 2014 Chartered Society of Physiotherapy.

This study aimed at determining the level of decisional conflict in asthmatic individuals facing recommendation-based decisions provided to improve asthma control. This was a cross-sectional study performed on a convenience sample of 50 adults aged between 18 and 65 years with a diagnosis of asthma. They completed a decisional conflict scale (possible range of 0-100%), asthma knowledge and control questionnaires (both 0% and 100%), and a general questionnaire on socio-demographic characteristics. A decisional conflict was considered clinically significant with a score greater than 37.5%. Simple descriptive statistics were used to investigate associations with decisional conflict. Participants were mainly women (76%) and diagnosed with mild asthma (72%). The median age (1st and 3rd quartile) was 25 years (22 and 42). The median score (1st and 3rd quartile) of decisional conflict was 33% (24 and 44). A clinically significant score (>37.5%) was obtained in 36% of subjects. A statistically significant negative correlation between the knowledge score and the decisional conflict score (r(p) = -0.38; p = 0.006) was observed. The level of knowledge was the only statistically independent variable associated with the decisional conflict score (p = 0.0043). A considerable proportion of patients with asthma have a clinically significant level of decisional conflict when facing decisions aimed at improving asthma control. Patients with poor knowledge of asthma are more at risk of clinically significant level of decisional conflict. These findings support the relevance of providing asthmatic patients with relevant information in decision aids.

This study which involved 140 Holstein and Montbeliard was carried out in the periurban area of Dakar with the aim to establish the relationship between ketosis, milk production and biochemical blood metabolites. The results showed that ketosis is a real problem in periurban farms around the city of Dakar with high proportions of 33.57% for subclinical ketosis and 6.43% for clinical ketosis. In their second month of milking, cows with subclinical ketosis had a decrease of 12.4 and 15.,6% in milk yield respectively for Montbeliard and Holstein, whereas cows with clinical ketosis had a decrease of 18.6 and 26%. Ketogenic cows (subclinical and clinical) have significantly lower average levels of blood glucose (p<0.05) and significantly higher average levels of blood urea (p<0.05) than cows with normal blood beta-Hydroxy Butyrate (BbHB) levels. Also, from one farm to another, significant difference was recorded with concentration of total proteins and globulin, calcium and magnesium.

Characterization of Change and Significance for Clinical Findings in Radiology Reports Through Natural Language Processing.

Hassanpour, Saeed; Bay, Graham; Langlotz, Curtis P

2017-06-01

We built a natural language processing (NLP) method to automatically extract clinical findings in radiology reports and characterize their level of change and significance according to a radiology-specific information model. We utilized a combination of machine learning and rule-based approaches for this purpose. Our method is unique in capturing different features and levels of abstractions at surface, entity, and discourse levels in text analysis. This combination has enabled us to recognize the underlying semantics of radiology report narratives for this task. We evaluated our method on radiology reports from four major healthcare organizations. Our evaluation showed the efficacy of our method in highlighting important changes (accuracy 99.2%, precision 96.3%, recall 93.5%, and F1 score 94.7%) and identifying significant observations (accuracy 75.8%, precision 75.2%, recall 75.7%, and F1 score 75.3%) to characterize radiology reports. This method can help clinicians quickly understand the key observations in radiology reports and facilitate clinical decision support, review prioritization, and disease surveillance.

To report the presentation, clinical course and prognosis of myasthenia gravis (MG) with thyroid disease. Retrospective data analysis was conducted.Between 2004 and 2013, we reviewed a total of 106 patients with MG. We analyzed the clinical features, the relationship between the thyroid function, antibodies and the clinical course, prognosis. (1) In our study, 20/106 (18.87%) patients were thyroid function-abnormal, 37/106 (34.91) were thyroglobulin antibodies (TGAb) and/or thyroid microsomal antibody (TMAb)-positive, and abnormality was observed in 46 (43.40%) of the thyroid gland. Thyroid antibody positive rate was higher than abnormal thyroid function rate, and the difference was significant (P=0.036). (2) The thyroid stimulating hormone (TSH) level ((2.9±4.0) mIU/L) of ocular MG was higher than the level ((1.5±1.1) mIU/L) of generalized MG (P=0.01). (3) The transformation time of 52 ocular type to generalized type was longer in higher antibody group than in normal group (P=0.04). And there were no significant differences between the elevated TSH type and the normal TSH type, the abnormal thyroid function type and normal thyroid function type, the abnormal thyroid type and the normal thyroid type. (4) Comparing the TSH level, total antibody level, TGAb, and TMAb level between the ease group and the unease group in the course of 1 year, 2 years, 5 years, there were no significant differences (all P>0.05). MG is often companied with thyroid abnormalities. MG patients are more susceptible to hashimoto thyroiditis and other autoimmune thyroid diseases. Ocular type patients are more likely to suffer from thyroid function decrease than the generalized type. MG patients with hashimoto thyroiditis and other autoimmune thyroid diseases are more sensitive to respond to therapy means like glucocorticoid therapy, and the short-term prognosis is relatively good. There are no significant correlations between the MG remission rate and TSH level, total antibody level, TGAb and TMAb level.

The aim of this meta-analysis was to assess effects of alpha-lipoic acid supplementation on C-reactive protein (CRP) levels in clinical trial studies. A systematic search was carried out on clinical trial studies published in PubMed, ISI Web of Science, Cochrane Library and Scopus databases completed by manual search on reference list of eligible studies accomplished by November 4, 2017. Of a total number of 508 studies found in the first step of literature search, only 11 were included with 264 participants in supplementation groups and 287 in control groups. Estimated pooled random effects size analysis showed a significant reducing effect of alpha-lipoic acid supplementation on CRP level (-0.72 mg/l, 95% CI; -1.4, -0.04; P = 0.03) with a significant heterogeneity between the selected studies. Sub-group analysis showed that alpha-lipoic acid supplementation could significantly reduce serum CRP level when the baseline CRP level was greater than 3 mg/l (-1.02 mg/l, 95% CI: -1.3, -0.73) and when trial duration was >8 weeks (-0.99 mg/l, 95% CI: -1.29, -0.70). Results of subgroup analysis also showed that alpha lipoic acid supplementation could decrease CRP level only in non-diabetic patients (-1.02 mg/l, 95% CI: -1.31, -0.74). Results of the current meta-analysis study showed that alpha-lipoic acid supplementation could significantly decrease CRP level in patients with elevated levels of this inflammatory marker.

Clinical success of oral implants is related to primary stability and osseointegration. These parameters are associated with delicate surgical techniques. We herein studied whether template-guided drilling has a significant influence on drillholes diameter and accuracy in an in vitro model. Fresh cadaveric porcine mandibles were used for drilling experiments of four experimental groups. Each group consisted of three operators, comparing guide templates for drilling with free-handed procedure. Operators without surgical knowledge were grouped together, contrasting highly experienced oral surgeons in other groups. A total of 180 drilling actions were performed, and diameters were recorded at multiple depth levels, with a precision measuring instrument. Template-guided drilling procedure improved accuracy on a very significant level in comparison with free-handed drilling operation (p ≤ 0.001). Inaccuracy of free-handed drilling became more significant in relation to measurement depth. High homogenic uniformity of template-guided drillholes was significantly stronger than unguided drilling operations by highly experienced oral surgeons (p ≤ 0.001). Template-guided drilling procedure leads to significantly enhanced accuracy. Significant results compared to free-handed drilling actions were achieved, irrespective of the clinical experience level of the operator. Template-guided drilling procedures lead to a more predictable clinical diameter. It shows that any set of instruments has to be carefully chosen to match the specific implant system. The current in vitro study is implicating an improvement of implant bed preparation but needs to be confirmed in clinical studies.

Although well established in chronic schizophrenia, the key determinants of functioning remain unknown during the early phase of a psychotic disorder. The aim of this study was to comprehensively examine the social cognitive, basic neurocognitive and clinical predictors of concurrent social functioning and global functioning in an early psychosis sample. This study examined the relationship between social cognition, basic neurocognition and clinical symptoms with concurrent functioning in 51 early psychosis individuals. Assessments included a range of self-report, observational and clinician-rated measures of cognitive, symptom severity and functioning domains. Results revealed a significant association between self-reported social function and lower levels of both social interaction anxiety and negative psychotic symptoms. A significant association was also observed between lower levels of negative psychotic symptoms and observed social functioning. Lastly, results demonstrated a significant association between reduced negative psychotic symptoms and clinician-rated global functioning. Clinical domains such as negative symptoms and social interaction anxiety significantly contribute to an optimal model predicting outcome during the early phase of a psychotic disorder. These clinical features may also provide useful markers of an individual's capacity for social participation. Clinical implications include the need for early targeted intervention to address social anxiety and negative psychotic symptoms to facilitate optimum patient outcome. © 2015 Wiley Publishing Asia Pty Ltd.

2017-12-01

The expression of ataxia-telangiectasia mutated (ATM) and p53 upregulated modulator of apoptosis (PUMA) genes in patients with colorectal cancer were investigated, to explore the correlation between the expression of ATM and PUMA and tumor development, to evaluate the clinical significance of ATM and PUMA in the treatment of colorectal cancer. Quantitative real-time PCR was used to detect the expression of ATM and PUMA in tumor tissue and adjacent healthy tissue of 67 patients with colorectal cancer and in normal colorectal tissue of 33 patients with colorectal polyps at mRNA level. The expression level of ATM mRNA in colorectal cancer tissues was significantly higher than that in normal mucosa tissues and adjacent non-cancerous tissue (P≤0.05), while no significant differences in expression level of ATM mRNA were found between normal mucosa tissues and adjacent noncancerous tissue (P=0.07). There was a negative correlation between the expression of ATM mRNA and the degree of differentiation of colorectal cancer (r= -0.312, P=0.013), while expression level of ATM mRNA was not significantly correlated with the age, sex, tumor invasion, lymph node metastasis or clinical stage (P>0.05). Expression levels of PUMA mRNA in colorectal cancer tissues, adjacent noncancerous tissue and normal tissues were 0.68±0.07, 0.88±0.04 and 1.76±0.06, respectively. Expression level of PUMA mRNA in colorectal cancer tissues and adjacent noncancerous tissue was significantly lower than that in normal colorectal tissues (P<0.05). The results showed that ATM mRNA is expressed abnormally in colorectal cancer tissues. Expression of PUMA gene in colorectal carcinoma is downregulated, and is negatively correlated with the occurrence of cancer.

Endotoxemia: methods of detection and clinical correlates.

PubMed Central

Hurley, J C

1995-01-01

As an assay for endotoxin, the Limulus amebocyte lysate assay has several desirable properties: sensitivity, specificity, and potential for adaptation to a quantitative format. Several modifications have been developed to enhance its potential for clinical application. The modifications that allow quantitative measurement of endotoxin and also improve its application to blood samples are described in this review. In fluids other than blood, the detection of endotoxin with the Limulus amebocyte lysate assay can be used as an aid to identify the presence of gram-negative bacteria, and the assay has established utility. With blood, however, there are a range of factors that interfere with the detection of endotoxemia and there are disparate views with respect to the diagnostic and prognostic significance of the test results. In general, the clinical significance of the finding of endotoxemia broadly parallels the frequency and importance of gram-negative sepsis in the patient groups studied and a decline in endotoxin levels accompanies clinical improvement. However, with therapies designed to reduce levels of endotoxin, or to antagonize its effects, it is unclear whether clinical improvement occurs as a consequence of changes in the levels of endotoxemia.

To assess the predictive ability of various aspects of the work environment for organizational commitment. A questionnaire measuring three dimensions of organizational commitment along with five aspects of work environment and 10 demographic and work setting characteristics was sent to a national, convenience sample of clinical laboratory professionals. All persons obtaining the CLS certification by NCA from January 1, 1997 to December 31, 2006. Only respondents who worked full-time in a clinical laboratory setting were included in the database. Levels of affective, normative, and continuance organizational commitment, organizational support, role clarity, role conflict, transformational leadership behavior of supervisor, and organizational type, total years work experience in clinical laboratories, and educational level of respondents. Questionnaire items used either a 7-point or 5-point Likert response scale. Based on multiple regression analysis for the 427 respondents, organizational support and transformational leadership behavior were found to be significant positive predictors of affective and normative organizational commitment. Work setting (non-hospital laboratory) and total years of work experience in clinical laboratories were found to be significant positive predictors of continuance organizational commitment. Overall the organizational commitment levels for all three dimensions were at the neutral rating or below in the slightly disagree range. The results indicate a less than optimal level of organizational commitment to employers, which were predominantly hospitals, by CLS practitioners. This may result in continuing retention problems for hospital laboratories. The results offer strategies for improving organizational commitment via the significant predictors.

Recent studies have demonstrated the beneficial effects of omega-3 polyunsaturated fatty acids (PUFAs) on physiological processes and on a variety of chronic inflammatory diseases, including periodontal diseases. In this study, we evaluated the impact of omega-3 PUFAs in conjunction with scaling and root planing (SRP) on salivary markers in patients with chronic periodontitis. Thirty systemically healthy subjects with chronic periodontitis were enrolled and randomly allocated into two groups. The control group (n = 15) was treated with SRP + placebo whereas the test group was treated with SRP and dietary supplementation of low-dose omega-3 PUFAs (6.25 mg eicosapentaenoic acid and 19.19 mg docosahexaenoic acid). Clinical parameters were taken at baseline, 1, 3 and 6 mo following therapy. Saliva samples were obtained at the same time intervals and analyzed for tumor necrosis factor-α (TNF-α) and superoxide dismutase (SOD). Both groups showed significant changes in clinical parameters in response to treatment compared to baseline with no significant difference between groups. Salivary TNF-α levels showed a statistically significant decrease in the test group at 6 mo compared to the control group. Salivary SOD levels increased significantly at 3 and 6 mo in the test group and at 6 mo in placebo groups compared to baseline with no statistically significant differences between the groups. The results demonstrated that dietary supplementation with low-dose omega-3 PUFAs improves salivary TNF-α without any significant impact on clinical parameters in patients with chronic periodontitis, suggesting that the systemic benefits of dietary omega-3 PUFAs may not be translated to periodontal health.

Emergency nurses play an important role in the care of critically ill and injured patients, and their competency to perform clinical skills is vital to safe and effective patient care. The aim of this study was to evaluate the frequency of clinical skills performed and perceived competency levels among Iranian emergency nurses. In addition, attitudes toward expanding the professional roles of Iranian emergency nurses were also assessed. In this descriptive correlational study, 319 emergency nurses from 30 hospitals in northwest Iran participated. Data were collected using a self-report questionnaire. Descriptive statistics and Pearson's correlation coefficient were used to present the findings. Overall competency of the emergency nurses was 73.31 ± 14.2, indicating a good level of perceived competence. The clinical skills most frequently performed were in the domains of organizational and workload competencies (3.43 ± 0.76), diagnostic function (3.25 ± 0.82), and the helping role (3.17 ± 0.83). A higher level of perceived competence was found for skills within these domains. Less frequently, participants performed skills within the domains of effective management of rapidly changing situations (2.70 ± 0.94) and administering and monitoring therapeutic interventions (2.60 ± 0.97); a lower perceived level of competence was noted for these clinical skills. There was a significant correlation between frequency of performing clinical skills and perceived competency level (r = 0.651, P < .001). Participants had positive attitudes toward expanding their professional roles (2.13 ± 0.92), with 81.5% agreeing it would improve their job satisfaction. Higher perceived competency levels were significantly associated with more frequent performance of clinical skills. This has implications for nurse managers and educators who may consider offering more frequent experiential and educational opportunities to emergency nurses. Expansion of nurses' roles could also result in increased experience in clinical skills and higher levels of competency. Research is needed to investigate nurses' clinical competence using direct and observed measures. Copyright © 2017 Emergency Nurses Association. Published by Elsevier Inc. All rights reserved.

Background: Nurses’ clinical competency plays an important role in the care of preterm infants. On the other hand, burnout is one of the most important factors in reducing the nurses’ efficiency. With regard to the importance of the role of nurses, and the vulnerability of the infants, the purpose of this study was to investigate the relationship between nurses’ burnout and clinical competency in NICUs. Materials and Methods: The descriptive cross-sectional study was conducted with the participation of 86 nurses working in the NICUs of hospitals in Isfahan, Iran. Census sampling method was used in the NICUs of educational hospitals in 2014. Data were collected by a questionnaire including demographic characteristics, Patricia clinical competency, and Maslach burnout scales. Data were analyzed by the statistical tests of independent t-test and Pearson correlations test with the significance level of α < 0.05. Results: Six dimensions of clinical competency and three dimensions of nurses’ burnout were assessed at three levels (weak, moderate, and strong levels). Statistical tests showed that clinical competency was at a moderate level in all fields. Of the dimensions of nurses’ burnout, emotional exhaustion was moderate, depersonalization was weak, and personal performance was strong. The results showed that nurses’ burnout and clinical competency in the NICUs were at a moderate level and had a significant negative relationship (r = −0.322, P = 0.003). Conclusions: Results showed that burnout had a negative relationship with competency. Therefore, managers are suggested to improve nurses’ competency and diminish their job burnout through better and more applicable planning. PMID:27563328

Insulin like growth factor 1 (IGF-1) is recognized as a potent mitogen for many cancer cell lines and there is good evidence that lung cancer cells produce both IGF-1 and insulin like growth factor binding protein 3 (IGFBP-3). The aim of this study was to investigate the clinical significance of IGF-1 and IGFBP-3 levels in serum and in bronchoalveolar lavage (BAL) fluid by comparing lung cancer patients with healthy controls. BAL fluid and serum samples were obtained from 24 lung cancer patients and 12 healthy controls, and were analyzed for IGF-1 and IGFBP-3 levels by a two site immunoradiometric assay. The recovered BAL fluid was standardized by albumin to remove the variable of dilution and the data was expressed in epithelial lining fluid (ELF). Serum IGF-1 and IGFBP-3 levels were lower in lung cancer patients, but the difference between the groups did not reach a statistical significance. IGF-1/IGFBP-3 ratio in ELF was significantly lower in lung cancer patients (P=0.035). Mean IGF-1 level in ELF was determined to be significantly lower in patients with distant metastasis (P=0.04). Serum IGF-1/IGFBP-3 ratio was found to be significantly lower in patients with distant (P=0.04) and nodal metastasis (P=0.03). Tumor stage was negatively correlated with IGF-1 level in ELF (P=0.05, r=-0.4) and serum IGF-1/IGFBP-3 ratio (P=0.04, r=-0.4). IGF-1 and IGFBP-3 levels both in serum and ELF might serve a clinical significance in patients with lung cancer. However, further studies comprising more cases are needed to investigate the clinical significance of IGF-1 and IGFBP-3 in lung cancer.

A pilot study of high dose coenzyme Q(10) (CoQ(10))/vitamin E therapy in Friedreich's ataxia (FRDA) patients resulted in significant clinical improvements in most patients. This study investigated the potential for this treatment to modify clinical progression in FRDA in a randomized double blind trial. Fifty FRDA patients were randomly divided into high or low dose CoQ(10)/ vitamin E groups. The change in International Co-operative Ataxia Ratings Scale (ICARS) was assessed over 2 years as the primary end-point. A post hoc analysis was made using cross-sectional data. At baseline serum CoQ(10) and vitamin E levels were significantly decreased in the FRDA patients (P < 0.001). During the trial CoQ(10) and vitamin E levels significantly increased in both groups (P < 0.01). The primary and secondary end-points were not significantly different between the therapy groups. When compared to cross-sectional data 49% of all patients demonstrated improved ICARS scores. This responder group had significantly lower baseline serum CoQ(10) levels. A high proportion of FRDA patients have a decreased serum CoQ(10) level which was the best predictor of a positive clinical response to CoQ(10)/vitamin E therapy. Low and high dose CoQ(10)/vitamin E therapies were equally effective in improving ICARS scores.

Endothelial dysfunction leads to worse cognitive performance in Alzheimer's dementia (AD). While both cerebrovascular risk factors and endothelial dysfunction lead to activation of vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1) and E-selectin, it is not known whether these biomarkers extend the diagnostic repertoire in reflecting intracerebral structural damage or cognitive performance. A total of 110 AD patients and 50 age-matched controls were enrolled. Plasma levels of VCAM-1, ICAM-1 and E-selectin were measured and correlated with the cognitive performance, white matter macro-structural changes, and major tract-specific fractional anisotropy quantification. The AD patients were further stratified by clinical dementia rating score (mild dementia, n=60; moderate-to-severe dementia, n=50). Compared with the controls, plasma levels of VCAM-1 (p< 0.001), ICAM-1 (p=0.028) and E-selectin (p=0.016) were significantly higher in the patients, but only VCAM-1 levels significantly reflected the severity of dementia (p< 0.001). In addition, only VCAM-1 levels showed an association with macro- and micro- white matter changes especially in the superior longitudinal fasciculus (p< 0.001), posterior thalamic radiation (p=0.002), stria terminalis (p=0.002) and corpus callosum (p=0.009), and were independent of, age and cortical volume. These tracts show significant association with MMSE, short term memory and visuospatial function. Meanwhile, while VCAM-1 level correlated significantly with short-term memory (p=0.026) and drawing (p=0.025) scores in the AD patients after adjusting for age and education, the significance disappeared after adjusting for global FA. Endothelial activation, especially VCAM-1, was of clinical significance in AD that reflects macro- and micro-structural changes and poor short term memory and visuospatial function.

Venous congestion has become increasingly recognized as a potential contributor to end-organ dysfunction in heart failure. Elevated I-FABP, which is excreted specifically from damaged intestinal epithelial cells, has been found in patients with abdominal hypertension and intestinal ischemia. We hypothesize that elevated intestinal fatty acid-binding protein (I-FABP) levels would identify patients with more advanced heart failure who have venous and intestinal congestion. Baseline serum I-FABP levels were measured in 69 acute decompensated heart failure (ADHF) patients admitted to the intensive care unit for invasive hemodynamic monitoring and tailored medical therapy. Comprehensive echocardiography examinations were performed in all study patients, and clinical outcomes (death, cardiac transplant or left ventricular assist device placement) were assessed. The median circulating I-FABP level was 853pg/ml (interquartile range: 533 to 1448pg/ml). Age, gender, race, and baseline comorbidities were comparable between patients with low and high I-FABP levels. Although there were no significant correlations between I-FABP levels and invasively-measured hemodynamic parameters nor echocardiographic parameters, patients with higher I-FABP levels (≥853g/ml) had significantly worse clinical outcomes compared to those with lower I-FABP levels (<853pg/ml, P=0.025). Circulating I-FABP levels had no association with invasively-measured hemodynamic parameters, but were associated with adverse clinical outcomes in patients with ADHF with systolic dysfunction.

Introduction Human toxocariasis is caused by several species of the nematode Toxocara. Two common clinical syndromes are ocular and visceral larva migrans. Objectives To determine the Toxocara antibody positivity in clinically suspected VLM patients and to describe demographic factors and clinical manifestations of seropositive patients. Methods 522 clinically suspected patients were studied between 1993 and 2014. Relevant data was gathered from referral letters. Serum samples were subjected to Toxocara antigen ELISA. Results Overall, seropositivity was 50.2% (262), of which 109 (40.8%) were positive at high level of Toxocara antibody carriage and 153 (58.4%) were positive at low levels. The seropositives ranged from 3 months to 70 years (mean = 7.8). Younger age group had higher levels of seropositivity and it was statistically significant. Majority of children under 5 years were seropositive (47.7%, n = 125). Seropositivity was common in males (55.3%, n = 145). Clinical manifestations of seropositives include lymphadenopathy (24.1%) skin rash (22.5%), dyspnoea (21.7%), fever (21%), hepatosplenomegaly (9.2%), and abdominal pain (3.8%). 197 (75.2%) seropositive cases had eosinophilia. These symptoms were not statistically significant. Conclusions This study confirms toxocariasis as an important cause of childhood ill health identifying common clinical symptoms recommending preventive measures to limit transmission. PMID:29362672

The need to increase the predictability of periodontal regeneration has encouraged clinicians and researchers to employ cell-stimulating proteins in combination with osteoconductive scaffolds, based on the principles of tissue engineering. The purpose of this clinical and radiographic study was to compare the regenerative potential of the combination of β-tricalcium phosphate (β-TCP) and recombinant human platelet-derived growth factor BB (rhPDGF-BB) in the grafting of intraosseous defects with the established technique of bone grafting with (β-TCP alone. A total of 30 sites from 15 patients with infrabony defects in two different quadrants were selected, and the sites were randomly divided into test sites (rhPDGF + β-TCP) and control sites (β-TCP alone) using a split-mouth design. Clinical parameters, including probing pocket depth, clinical attachment level, and gingival recession, were recorded at baseline, 6 months, and 9 months. Radiographic evaluation was carried out to evaluate defect fill, change in alveolar crest height, and percentage of defect fill at baseline, 6 months, and 9 months. Both the experimental groups showed statistically significant reduction in probing pocket depth and gain in clinical attachment level. On intergroup comparison, sites treated with rhPDGF + β-TCP demonstrated a significantly greater pocket depth reduction (P < .05) and greater gain in clinical attachment level (P < .01). Mean percentage defect fill was significantly greater in test sites as compared with control sites at 6 and 9 months (P < .01). rhPDGF + β-TCP-treated sites demonstrated a significant gain in mean alveolar crest height at 6 and 9 months (P < .05), while β-TCP-treated sites demonstrated crestal resorption. Both groups demonstrated potential in enhancing periodontal regeneration; however, on comparison between the two groups, the results obtained by rhPDGF + β-TCP were significantly better with respect to both clinical and radiographic parameters.

Bipolar disorder (BD), especially BD-II, is frequently comorbid with alcohol dependence. Because BD-II and alcohol dependence are neurodegenerative disorders, agents with anti-inflammatory and neurotrophic effects might provide effective therapy. We investigated whether add-on memantine to regular valproic acid treatment ameliorated clinical symptoms, reduced alcohol use, and cytokine levels, and increased plasma brain-derived neurotrophic factor (BDNF) in BD-II patients with comorbid alcohol dependence. In a single-arm 12-week clinical trial, BD-II patients with comorbid alcohol dependence (n = 45) undergoing regular valproic acid treatments were given add-on memantine (5 mg/d). Symptom severity, alcohol use, cytokine (plasma tumor necrosis factor-α and C-reactive protein [CRP], transforming growth factor-β1 [TGF-β1], interleukin-8 [IL-8], IL-10), and plasma BDNF levels were regularly assessed. Mean within-group decreases in Hamilton Depression Rating Scale (HDRS) and Young Mania Rating Scale (YMRS) scores, alcohol use, CRP, BDNF, and IL-8 levels were significantly different from baseline after 12 weeks of treatment. We found no significant correlation between alcohol use levels and changes in HDRS or YMRS scores. The correlation between reduced alcohol use and reduced TGF-β1 level was significant (B = 0.003, p = 0.019). BD-II comorbid with alcohol dependence might benefit from add-on memantine treatment, which significantly reduced clinical severity, alcohol use, and plasma cytokine levels, and increased BDNF levels.

Compare the effects of a combined contraceptive pill (OCP) in combination with myo-inositol (MI) on endocrine, metabolic, and clinical parameters in patients with polycystic ovary syndrome (PCOS). One hundred fifty-five patients with PCOS were enrolled in this prospective, open-label clinical study. Patients were assigned to receive oral treatment with OCP alone (estradiol (EE) 30 μg/gestodene 75 μg) or in combination with myo-inositol 4 g/die, for 12 months. OCP plus MI therapy resulted in a higher reduction of FG score compared with OCP alone therapy. The combined therapy (OCP plus MI) significantly decreased hyperinsulinaemia, by positively affecting the fasting insulin and glucose levels and homeostasis model assessment-insulin resistance parameters, while no significant changes were observed in the OCP group. Androgens serum levels decreased in both groups, but significantly more in the combined therapy group. The lipid profile was improved in the combined therapy group, by reducing low-density lipoprotein cholesterol levels and enhancing high-density lipoprotein cholesterol levels. Our data show that a combination of combined contraceptive pill and MI may be more effective in controlling endocrine, metabolic, and clinical profile in patients with PCOS than OCP alone, and may reduce insulin levels and insulin resistance. Hence, combined treatment may become a more effective long-term therapeutic choice for controlling PCOS symptoms.

It has been documented previously that defects in the generation of C18-ceramide, a product of ceramide synthase 1 (CerS1), also known as longevity assurance gene 1 (hLASS1), play important roles in the pathogenesis and/or progression of HNSCC. However, whether altered levels of ceramide generation in HNSCC tumors have any clinical relevance remains unknown. In this study, the levels of endogenous ceramides were measured in tumor tissues of 45 HNSCC patients as compared to their normal tissues using high-pressure liquid chromatography/mass spectrometry (LC/MS), and then possible link between ceramide levels and the clinical parameters of HNSCC were examined. The data showed that the levels of C16-, C24-, C24:1-ceramide were significantly elevated in the majority of tumor tissues compared to their normal tissues, while the levels of only C18-ceramide were significantly decreased in HNSCC tumors, especially in tumor tissues of male patients. Importantly, it was also shown here that decreased C18-ceramide levels in HNSCC tumor tissues were significantly associated with the higher incidences of lymphovascular invasion, and pathologic nodal metastasis. Importantly, attenuation of C18-ceramide was also positively linked to the higher overall stages of the primary HNSCC tumors. Therefore, these data suggest, for the first time, that the defects in the generation/accumulation of C18-ceramide might have important clinical roles in HNSCC, especially in lymphovascular invasion and nodal disease.

Although soluble forms of the receptor for advanced glycation end products (RAGE) have been recently proposed as biomarkers in multiple acute or chronic diseases, few studies evaluated the influence of usual clinical and biological parameters, or of patient characteristics and comorbidities, on circulating levels of soluble RAGE in the intensive care unit (ICU) setting. To determine, among clinical and biological parameters that are usually recorded upon ICU admission, which variables, if any, could be associated with plasma levels of soluble RAGE. Data for this ancillary study were prospectively obtained from adult patients with at least one ARDS risk factor upon ICU admission enrolled in a large multicenter observational study. At ICU admission, plasma levels of total soluble RAGE (sRAGE) and endogenous secretory (es)RAGE were measured by duplicate ELISA and baseline patient characteristics, comorbidities, and usual clinical and biological indices were recorded. After univariate analyses, significant variables were used in multivariate, multidimensional analyses. 294 patients were included in this ancillary study, among whom 62% were admitted for medical reasons, including septic shock (11%), coma (11%), and pneumonia (6%). Although some variables were associated with plasma levels of RAGE soluble forms in univariate analysis, multidimensional analyses showed no significant association between admission parameters and baseline plasma sRAGE or esRAGE. We found no obvious association between circulating levels of soluble RAGE and clinical and biological indices that are usually recorded upon ICU admission. This trial is registered with NCT02070536.

To assess the correlation between the levels of vitamin D in follicular fluid and serum, and to determine whether the level of 25-hydroxyvitamin D (25OH-D) in follicular fluid of infertile women undergoing assisted reproductive technology (ART) is associated with the outcome. Eighty-two infertile women undergoing ART at an academic tertiary care centre were recruited for a prospective cohort study. Levels of 25OH-D in follicular fluid and serum were measured. Standardized regimens for pituitary downregulation and controlled ovarian hyperstimulation were employed. Patient and cycle parameters, and clinical pregnancy (defined as evidence of intra-uterine gestation sac plus heart rate on ultrasound) were determined. A significant correlation was found between the levels of vitamin D in follicular fluid and serum (r=0.767, p=0.001). The overall rates of chemical, clinical and ongoing pregnancy were 35.5% (n=29), 29.3% (n=24) and 23.2% (n=19), respectively. No significant difference was found in these pregnancy rates between the tertiles of 25OH-D level in follicular fluid (p=0.959, 0.995 and 0.604, respectively). The median serum level of vitamin D was 8.13 (range 5.37-13.62)ng/ml in the clinically pregnant group and 8.29 (range 5.93-21.23)ng/ml in the non-pregnant group (p=0.235). Interestingly, the median level of vitamin D in follicular fluid was 9.19 (range 5.25-19.51)ng/ml in the clinically pregnant group and 10.34 (range 5.89-29.69)ng/ml in the non-pregnant group (p=0.433). The fertilization rate decreased significantly and the implantation rate increased (not significantly) with increasing tertiles of 25OH-D level in follicular fluid. The level of 25OH-D in follicular fluid is reflective of body stores of vitamin D. Most subjects in this study were deficient in vitamin D, but this study found that vitamin D deficiency does not play a pivotal role in the outcome of ART. Copyright © 2011 Elsevier Ireland Ltd.

Serum ACE levels correlated significantly with /sup 67/Ga uptake score (r..436; p less than .005). The frequency of abnormalmore » /sup 67/Ga scans and elevated serum ACE levels suggests that inflammatory activity with little or no clinical expression is common in sarcoidosis. Abnormal /sup 67/Ga scans were highly sensitive (97%) but had poor specificity (29%) to clinical disease activity.

The current study investigated the efficacy of two brief intervention programs-biofeedback and mindfulness meditation-on levels of state anxiety and perceived stress in second-year Thai nursing students as they began clinical training. Eighty-nine participants from a public nursing college in Thailand were randomly assigned to one of three groups: biofeedback group, mindfulness meditation group, or a control group. All participants were given pre- and postintervention surveys, which included demographic information; the State-Trait Anxiety Inventory (State Anxiety Scale); and the Perceived Stress Scale. Findings indicated that biofeedback significantly reduced anxiety and maintained stress levels in nursing students. Mindfulness meditation similarly decreased anxiety levels, while also significantly lowering stress levels. The biofeedback group exhibited significant reduction in anxiety levels among the three groups at postintervention. Despite stressors and demands nursing students experience as they begin clinical practice, study findings support the use of biofeedback and mindfulness meditation interventions to assist nursing students in managing stress and anxiety.

A recent animal study showed that parathyroid hormone-related peptide (PTHrP) is associated with cancer cachexia by promoting adipose tissue browning, and we previously demonstrated that PTHrP predicts weight loss (WL) in patients with cancer. In this study, we investigated whether prediction of WL by PTHrP is influenced by clinical factors such as serum albumin, corrected calcium levels, cancer stage, and performance status (PS). A cohort of 219 patients with cancer whose PTHrP level was measured was enrolled and followed for body weight (BW) changes. Subjects were divided into two groups by serum albumin (cutoff value, 3.7 g/dL), corrected calcium (cutoff value, 10.5 mg/dL), cancer stage (stage 1 to 3 or 4), or PS (Eastern Cooperative Oncology Group 0 to 1 or 2 to 4), respectively. Clinically significant WL was defined as either percent of BW change (% BW) <-5% or % BW <-2% plus body mass index (BMI) <20 kg/m². After a median follow-up of 327 days, 74 patients (33.8%) experienced clinically significant WL. A positive PTHrP level was associated with a 2-fold increased risk of WL after adjusting for age, baseline BMI, serum albumin, corrected calcium level, cancer stage, and PS. The effect of PTHrP on WL remained significant in patients with low serum albumin, stage 4 cancer, and good PS. Regardless of calcium level, the effect of PTHrP on WL was maintained, although there was an additive effect of higher calcium and PTHrP levels. Early recognition of patients with advanced cancer who are PTHrP positive with hypercalcemia or hypoalbuminemia is needed for their clinical management. Copyright © 2018 Korean Endocrine Society.

The purpose of this study is to analyze the correlation between preoperative/postoperative Cytokeratin 19 (CK19) messenger RNA (mRNA) level in peripheral blood (PB) and the clinical significance in esophageal cancer patients with different clinicopathological factors. We detected the preoperative and postoperative CK19 mRNA level in the PB of 139 esophageal cancer patients who underwent complete resection and evaluated its clinical significance. We found that both the preoperative and postoperative CK19 mRNA level increased in the esophageal cancer patients with lymph node metastasis, relapse or distant metastasis compared with that in cancers without lymph node metastasis, relapse or distant metastasis. High postoperative CK19 mRNA levels indicate a short disease-free survival (DFS) for the whole cohort esophageal cancer patients, whereas the high preoperative CK19 mRNA levels only indicate a short DFS for the esophageal cancer patients with squamous cell carcinoma, TNM III stage, and lymph node metastasis. The dynamic change of CK19 mRNA levels could indicate the prognosis of esophageal cancer patients. The patients with decreasing CK19 mRNA level after surgery had good prognosis, and the patients with changeless CK19 mRNA level had poor prognosis. Taken together, CK19 mRNA levels could be a promising marker in assessing prognosis or assigning treatment for the esophageal cancer patients according to different clinicopathological factors. © 2015 International Society for Diseases of the Esophagus.

Background Acute coronary syndrome (ACS) can complicate acute ischemic stroke, causing significant morbidity and mortality. To date, literatures that describe poststroke acute coronary syndrome and its morbidity and mortality burden are lacking. Methods This is a single center, retrospective study where clinical characteristics, cardiac evaluation, and management of patients with suspected poststroke ACS were compared and analyzed for their association with inpatient mortality and 1-year all-cause mortality. Results Of the 82 patients, 32% had chest pain and 88% had ischemic ECG changes; mean peak troponin level was 18, and mean ejection fraction was 40%. The medical management group had older individuals (73 versus 67 years, p < 0.05), lower mean peak troponin levels (12 versus 49, p < 0.05), and lower mean length of stay (12 versus 25 days, p < 0.05) compared to those who underwent stent or CABG. Troponin levels were significantly associated with 1-year all-cause mortality. Conclusion Age and troponin level appear to play a role in the current clinical decision making for patient with suspected poststroke ACS. Troponin level appears to significantly correlate with 1-year all-cause mortality. In the management of poststroke acute coronary syndrome, optimal medical therapy had similar inpatient and all-cause mortality compared to PCI and/or CABG. PMID:29130017

Ubiquitin-like, containing PHD and RING finger domains 1 (UHRF1) has been reported to play an important role in breast carcinogenesis. This work investigated the correlation of UHRF1 DNA level in plasma with clinical characteristics of breast cancer and its clinical significance in breast cancer diagnosis. The expression of UHRF1 in primary breast cancer tissue was examined by Western blot. The UHRF1 DNA levels in plasma and UHRF1 mRNA expression in tissues were determined by accurate real-time quantitative PCR. The associations of UHRF1 levels with clinical variables were evaluated using standard statistical methods. The UHRF1 DNA in plasma of 229 breast cancer patients showed higher expression than healthy controls, which showed high specificity up to 76.2% at a sensitivity of 79.2%, and was significantly associated with c-erbB2 positive status, cancer stage and lymph node metastasis. High UHRF1 DNA level in plasma was significantly associated with short progression-free survival. The UHRF1 DNA level in plasma is highly correlative with breast cancer and its status and stage, and may be a potential independent diagnostic and prognostic factor for both breast cancer and the survival of breast cancer patients. © 2012 Japanese Cancer Association.

The current study examined the extent to which symptom improvement and full return to work occurs among clinically burnt-out employees and what the influence of concurring sleep problems is with respect to health recovery. Fifty-nine burnt-out employees on extended sick leave assessed their symptoms for 2 weeks using an electronic diary. After 6 months, the measurements were repeated. Symptom levels were compared with those of a healthy reference group that was assessed only once. After 6 months, all burnout symptoms had decreased significantly, and full return to work was achieved by 37% of the burnt-out individuals. The symptom levels at 6 months of follow-up among those who had fully returned to work were similar to healthy levels and significantly lower than the levels of those still on sick leave. The persons who benefited poorly from sleep at baseline had higher exhaustion levels at follow-up than those who benefited from sleep. Trouble falling asleep and less refreshing sleep at baseline hampered eventual full work resumption. The results show that a significant number of clinically burnt-out employees is able to recover in a 6-month period and that sleep plays an important role both in symptom improvement and in return to work.

Depression and anxiety are prevailing mental problem in patients on chronic hemodialysis and they have great influence on outcome of illness. Additionally, these disorders are rarely identified in that population of patients and they are insufficiently treated. The aim of this study was to assess the prevalence of depression and anxiety in patients on chronic hemodialysis in University Clinical Hospital Mostar and to examine the correlation between the demographic variables and the time spent on dialysis with depression and anxiety levels. The experimental group consisted of 56 patients on chronic hemodialysis in Mostar Clinical Hospital. The control group 1 consisted of 53 patients diagnosed with a chronic illness and treated for at least a year, while the control group 2 consisted of 51 persons who were not diagnosed with any chronic somatic or mental illness. Demographic data were collected using the constructed questionnaire. The Beck Depression Inventory-BDI was used to determine depression, while the Spielberger State-Trait Anxiety Inventory-STAI was used to determine anxiety. We recorded significantly higher prevalence of depression in patients on chronic dialysis (51.8%) than in patients with a chronic illness (41.5%) and persons without chronic illnesses (9.8%; p < 0.001). Trait anxiety level was significantly higher in hemodialysed patients compared to the other two groups (p = 0.006) but there were no significant differences in state anxiety level. The study has not shown any significant difference in the prevalence of depression and anxiety level regarding the differences in sex, gender and education level, apart from a higher level of state anxiety in patients with a lower education level (p = 0.032). These results indicate that patients on hemodialysis have a significantly higher level of depression and a higher level of trait anxiety compared to patients with chronic illnesses and especially compared to general population.

To investigate the relationship of coronary heart disease (CHD)-associated factors-C-reactive protein (CRP) and lipid profiles-with periodontitis in an ethnic Han population. Forty healthy individuals as control, 40 patients with chronic periodontitis (CP), 28 patients with CHD, and 47 patients with both CP and CHD were included in the study. Serum CRP levels, lipid profile concentrations, and three periodontal clinical parameters (probing depth, clinical attachment level, and bleeding on probing) were measured and analyzed. The chi-square test, Student-Newman-Keuls test, analysis of covariance, and a logistic regression analysis were used in this study. The mean CRP level of patients with CP alone was 2.4 +/- 1.5 mg/L. There were significant differences in mean serum CRP levels among groups after confounders were adjusted, with CP+CHD patients having the highest level (7.3 +/- 5.7 mg/L) and the controls the lowest (1.0 +/- 0.6 mg/L) (P < .001). Mean HDL cholesterol level of CP patients (1.1 +/- 0.7 mmol/L) was significantly lower than that of controls (1.4 +/- 0.6 mmol/L) (P < .05), although it was significantly higher than that of the other two groups with CHD (0.8 +/- 0.5 mmol/L and 0.7 +/- 0.4 mmol/L) (P < .001). Significant correlations of CRP and HDL cholesterol with the three clinical periodontal parameters were apparent (P < .05). CRP and HDL cholesterol were found to be significantly associated with an increased frequency of CHD in this regression model (OR = 3.7 and OR = 1.9, respectively, P < .05). In an ethnic Han population with a low normal range of serum CRP levels, chronic periodontitis is associated with increased CRP levels and decreased HDL cholesterol concentrations, which suggests that there may be some relationship between periodontal inflammation and CHD.

Implementation of Departmental Quality Strategies Is Positively Associated with Clinical Practice: Results of a Multicenter Study in 73 Hospitals in 7 European Countries

2015-01-01

Background Given the amount of time and resources invested in implementing quality programs in hospitals, few studies have investigated their clinical impact and what strategies could be recommended to enhance its effectiveness. Objective To assess variations in clinical practice and explore associations with hospital- and department-level quality management systems. Design Multicenter, multilevel cross-sectional study. Setting and Participants Seventy-three acute care hospitals with 276 departments managing acute myocardial infarction, deliveries, hip fracture, and stroke in seven countries. Intervention None. Measures Predictor variables included 3 hospital- and 4 department-level quality measures. Six measures were collected through direct observation by an external surveyor and one was assessed through a questionnaire completed by hospital quality managers. Dependent variables included 24 clinical practice indicators based on case note reviews covering the 4 conditions (acute myocardial infarction, deliveries, hip fracture and stroke). A directed acyclic graph was used to encode relationships between predictors, outcomes, and covariates and to guide the choice of covariates to control for confounding. Results and Limitations Data were provided on 9021 clinical records by 276 departments in 73 hospitals. There were substantial variations in compliance with the 24 clinical practice indicators. Weak associations were observed between hospital quality systems and 4 of the 24 indicators, but on analyzing department-level quality systems, strong associations were observed for 8 of the 11 indicators for acute myocardial infarction and stroke. Clinical indicators supported by higher levels of evidence were more frequently associated with quality systems and activities. Conclusions There are significant gaps between recommended standards of care and clinical practice in a large sample of hospitals. Implementation of department-level quality strategies was significantly associated with good clinical practice. Further research should aim to develop clinically relevant quality standards for hospital departments, which appear to be more effective than generic hospital-wide quality systems. PMID:26588842

A directed acyclic graph was used to encode relationships between predictors, outcomes, and covariates and to guide the choice of covariates to control for confounding. Data were provided on 9021 clinical records by 276 departments in 73 hospitals. There were substantial variations in compliance with the 24 clinical practice indicators. Weak associations were observed between hospital quality systems and 4 of the 24 indicators, but on analyzing department-level quality systems, strong associations were observed for 8 of the 11 indicators for acute myocardial infarction and stroke. Clinical indicators supported by higher levels of evidence were more frequently associated with quality systems and activities. There are significant gaps between recommended standards of care and clinical practice in a large sample of hospitals. Implementation of department-level quality strategies was significantly associated with good clinical practice. Further research should aim to develop clinically relevant quality standards for hospital departments, which appear to be more effective than generic hospital-wide quality systems.

Patients with juvenile idiopathic arthritis often develop chronic anterior uveitis (JIAU). JIAU patients possess a particularly high risk for developing secondary glaucoma when inflammatory inactivity has been achieved. By using multiplex bead assay analysis, we assessed levels of pro- and anti-inflammatory cytokines, chemokines, or metalloproteinases in the aqueous humor (AH) of patients with clinically inactive JIAU with (JIAUwG) or without secondary glaucoma (JIAUwoG), or from patients with senile cataract as controls. Laser-flare photometry analysis prior to surgery showed no significant differences between JIAUwG or JIAUwoG. Compared with the control group, levels of interleukin-8, matrix metalloproteinase-2, -3, -9, serum amyloid A (SAA), transforming growth factor beta-1, -2, -3 (TGFβ-1, -2, -3), and tumor necrosis factor-alpha in the AH were significantly higher in patients with clinically inactive JIAUwG or JIAUwoG. Samples from JIAwoG patients displayed significantly higher levels of SAA ( P  < 0.0116) than JIAUwG patients. JIAUwG patients showed an increased level of TGFβ-2 in AH samples compared with JIAUwoG ( P  < 0.0009). These molecules may contribute to the clinical development of glaucoma in patients with JIAU.

Stem cell therapy has been applied in the treatment of acute-on-chronic liver failure (ACLF). However, its clinical efficiency is still debatable. The aim of this systematic review and meta-analysis is to evaluate the clinical efficiency of stem cell therapy in the treatment of ACLF. The Cochrane Library, OVID, EMBASE, and PUBMED were searched to December 2017. Both randomized and non-randomized studies, assessing stem cell therapy in patients with ACLF, were included. The outcome measures were total bilirubin (TBIL), alanine transaminase (ALT), international normalized ratio (INR), albumin (ALB), and the model for end-stage liver disease (MELD) score. The quality of evidence was assessed by GRADEpro. Four randomized controlled trials and six non-randomized controlled trials were included. The TBIL levels significantly decreased at 1-, 3-, 12-month after the stem cell therapy (p = 0.0008; p = 0.04; p = 0.007). The ALT levels decreased significantly compared with the control group in the short-term (p < 0.00001). There was no obvious change in the INR level compared with the control groups (p = 0.64). The ALB levels increased markedly as compared with the control groups (p < 0.0001). The significant difference can be found in MELD score between stem cell therapy and control groups (p = 0.008). Further subgroup analysis for 3-month clinical performance according to the stem cell types have also been performed. This study suggests that the clinical outcomes of stem cell therapy were satisfied in patients with ACLF in the short-term. MSCs may be better than BM-MNCs in the stem cells transplantation of ACLF. However, more attention should focus on clinical trials in large-volume centers.

To study the clinical value of combined detection of 4 tumor markers, namely lactic dehydrogenate (LDH), tissue polypeptide specific antigen (TPS), carcinoembryonic antigen (CEA) and beta2-microglobulin (beta2-MG) in patients with non-Hodgkin's lymphoma (NHL). The serum level of LDH was determined with automatic biochemical analyzer and TPS, CEA and beta2-MG levels were determined by enzyme-linked immumosorbent assay (ELISA) in 59 patients with NHL and 40 healthy adults. The levels of the 4 tumor markers were significantly higher in NHL patients than in the healthy control subjects (P<0.05). After chemotherapy, the serum levels of TPS and beta2-MG were significantly lowered in the patients who showed favorable response to the treatment (P<0.05), but the levels of LDH and CEA showed no significant change (P>0.05). The serum levels of LDH, TPS, CEA and beta2-MG in the patients in a stable or progressive phase did had no significant changes after chemotherapy (P>0.05). Combined detection of LDH, TPS, CEA and beta2-MG can be helpful to assist diagnosis of NHL and treatment evaluation.

Numerous studies have documented the clinical outcomes of laser therapy for untreated periodontitis, but very few have reported on lasers treating inflamed pockets during maintenance therapy. The aim of this study is to compare the effectiveness of scaling and root planing (SRP) plus the adjunctive use of diode laser therapy to SRP alone on changes in the clinical parameters of disease and on the gingival crevicular fluid (GCF) inflammatory mediator interleukin-1β (IL-1β) in patients receiving regular periodontal maintenance therapy. This single-masked and randomized, controlled, prospective study includes 22 patients receiving regular periodontal maintenance therapy who had one or more periodontal sites with a probing depth (PD) ≥ 5 mm with bleeding on probing (BOP). Fifty-six sites were treated with SRP and adjunctive laser therapy (SRP + L). Fifty-eight sites were treated with SRP alone. Clinical parameters, including PD, clinical attachment level (CAL), and BOP, and GCF IL-1β levels were measured immediately before treatment (baseline) and 3 months after treatment. Sites treated with SRP + L and SRP alone resulted in statistically significant reductions in PD and BOP and gains in CAL. These changes were not significantly different between the two therapies. Similarly, differences in GCF IL-1β levels between SRP + L and SRP alone were not statistically significant. In periodontal maintenance patients, SRP + L did not enhance clinical outcomes compared to SRP alone in the treatment of inflamed sites with ≥ 5 mm PD.

This study aimed to examine the IL-1β, IL-1ra, and IL-10 cytokine levels in gingival crevicular fluid (GCF) and serum of familial Mediterranean fever (FMF) and chronic periodontitis (CP) patients, and their response to nonsurgical periodontal therapy. A total of 50 patients, 15 FMF patients with generalized chronic periodontitis (FMF-CP), 15 systemically healthy patients with generalized chronic periodontitis (CP), ten systemically and periodontal healthy controls (HC), and ten periodontally healthy FMF patients (FMF-HC) were enrolled in the study. The cytokine levels in GCF and serum were determined by ELISA. Probing depth, clinical attachment level, and gingival and plaque indices in each participant were also measured. The GCF and clinical parameters at baseline and 6 weeks were recorded. The study indicated statistically significant healing of the clinical parameters in both FMF-CP and CP groups after periodontal treatment. GCF IL-1β levels at 6 weeks in FMF-CP group were significantly lower than the CP group (p < 0.05), and GCF IL-1ra levels were significantly decreased at 6 week in the FMF-CP group (p < 0.05). GCF IL-10 levels were significantly higher in the FMF-CP group than in the other groups at baseline and 6 weeks (p < 0.05). There were no significant differences in serum-IL-1β, IL-1ra, and IL-10 levels either FMF-CP or CP groups at baseline or 6 weeks (p > 0.05). The results of our study suggested that there was a positive correlation between gingival inflammation and serum cytokine levels in FMF patients and also colchicine treatment showed protective effects on GCF cytokine levels in FMF-CP group. Following treatment, GCF IL-1β and GCF IL-1ra levels were decreased in FMF-CP group. GCF IL-10 levels were increased in FMF-CP group compared to other groups. Also, the serum cytokine levels associated with periodontal inflammation in FMF patients.

The α hemoglobin stabilizing protein (AHSP) binds α-Hb and prevents its precipitation limiting free α-Hb toxicities. Our aim was to study AHSP expression in β thalassemia syndromes in relation to their clinical severity and to compare it with its level in sickle cell anemia. We compared patients with β-thalassemia (n=37) (β-thalassemia major (BTM) (n=19) and β-thalassemia intermedia (BTI) (n=18)) with 12 patients with sickle cell anemia as regards clinical severity, age at presentation, transfusion dependency, mean pre-transfusion hemoglobin level, use of hydroxyurea and AHSP expression by real time quantitative PCR. Median (and IQR) AHSP expression was significantly higher in patients with sickle cell anemia 2275 (3898) compared to thalassemia 283 (718), P=0.001, with no significant difference between BTM and BTI (P=0.346). It was also significantly higher in non-transfusion dependent patients with β thalassemia (NTDT) compared to transfusion dependent ones (P=0.019), and in patients on hydroxyurea therapy (P<0.001). However, there was no significant difference in its level according to clinical severity score (P=0.946) or splenectomy status (P=0.145). AHSP expression was higher in patients with sickle cell anemia versus thalassemia, with no significant difference between BTM and BTI. Expression was higher in patients with NTDT and on hydroxyurea therapy. Copyright © 2015 Elsevier Inc. All rights reserved.

To investigate the clinical outcomes of metastatic prostate cancer patients and the relationship between nadir prostate-specific antigen (PSA) levels and different types of primary androgen deprivation therapy (PADT). This study utilized data from the Japan Study Group of Prostate Cancer registry, which is a large, multicenter, population-based database. A total of 2982 patients treated with PADT were enrolled. Kaplan-Meier analysis was used to compare progression-free survival (PFS) and overall survival (OS) in patients treated using combined androgen blockade (CAB) and non-CAB therapies. The relationships between nadir PSA levels and PADT type according to initial serum PSA levels were also investigated. Among the 2982 enrolled patients, 2101 (70.5 %) were treated with CAB. Although CAB-treated patients had worse clinical characteristics, their probability of PFS and OS was higher compared with those treated with a non-CAB therapy. These results were due to a survival benefit with CAB in patients with an initial PSA level of 500-1000 ng/mL. Nadir PSA levels were significantly lower in CAB patients than in non-CAB patients with comparable initial serum PSA levels. A small survival benefit for CAB in metastatic prostate cancer was demonstrated in a Japanese large-scale prospective cohort study. The clinical significance of nadir PSA levels following PADT was evident, but the predictive impact of PSA nadir on OS was different between CAB and non-CAB therapy.

The aim of this study was to examine lumbar CSF-VEGF levels from elderly patients with ventriculomegaly to evaluate the possible circadian or periodic concentration profile and relevance to the prediction of drainage response. Lumbar CSF samples were collected in 1-h interval over 35 h from 22 patients with ventriculomegaly. CSF-VEGF levels were measured to elucidate the possible circadian or periodic concentration profiles. These VEGF levels were evaluated for correlations with clinical response to CSF drainage, ventricle size and other clinical information. The 35-h CSF-VEGF levels demonstrated a periodic concentration pattern with significant episodic fluctuation with 3-5h intervals. CSF-VEGF levels in non-responder group in which patients did not show clinical improvement with CSF drainage were significantly higher than these in responder group. VEGF variation in hydrocephalus patients suggests its possible pathophysiological role in hydrocephalus. The periodic concentration pattern of CSF-VEGF must be considered when choosing the most appropriate time for sample collection or clinical manipulation. Increased VEGF level in patients who showed no improvement with CSF drainage suggests that a possible greater ischemic or vascular injury may play a role in these patients. Pending further studies, these results suggest that high VEGF levels have a potential application in predicting non-responder patients with CSF drainage and so reducing the morbidity and cost of drainage and shunting in these patients.

This study evaluated the effect of cinnamon on disease activity, serum levels of some inflammatory markers, and cardiovascular risk factors in women with rheumatoid arthritis (RA). In this randomized double-blind clinical trial, 36 women with RA were randomly divided to 2 groups, receiving 4 capsules of either 500 mg cinnamon powder or placebo daily for 8 weeks. Fasting blood sugar (FBS), lipid profile, liver enzymes, serum levels of C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), erythrocyte sedimentation rate (ESR), blood pressure, and clinical symptoms were determined at baseline and end of the week 8. At the end of the study, there was a significant decrease of serum levels of CRP (p < 0.001) and TNF-α (p < 0.001) in the cinnamon group as compared to the placebo group. Diastolic blood pressure was also significantly lower in the intervention group compared with the control group (p = 0.017). Compared with placebo, cinnamon intake significantly reduced the Disease Activity Score (DAS-28) (p < 0.001), Visual Analogue Scale (VAS) (p < 0.001), and tender (TJC) (p < 0.001) and swollen joints (SJC) (p < 0.001) counts. No significant changes were observed for FBS, lipid profile, liver enzymes, or ESR. Cinnamon supplementation can be a safe and potential adjunct treatment to improve inflammation and clinical symptoms in patients with RA.

To the author's knowledge, there has been no study that has assessed clinical, radiographic, and immunological peri-implant parameters among individuals vaping e-cigarette (e-cig). This pilot study aimed to compare clinical and radiographic peri-implant parameters and levels of tumor necrosis factor alpha (TNF-α) and interleukin (IL)-1β levels among individuals vaping e-cigs and never smoker (NS). Forty-seven individuals vaping e-cigs (group-1) and 45 NS (group-2) were included. Demographic and implant-related data were collected using a structured baseline questionnaire. Peri-implant plaque index (PI), bleeding on probing (BOP), and probing depth (PD) were recorded and peri-implant bone loss (PIBL) were assessed using standardized digital radiographs. Enzyme-linked immunosorbent assay was used to assess the levels of TNF-α and IL-1β in peri-implant sulcular fluid. Bleeding on probing showed statistically significantly higher values in group-2 patients as compared to group-1 patients (P < .01). Probing depth ≥ 4 mm and PIBL was statistically significantly higher in group-1 patients as compared to group-2 patients (P < .05). Mean concentrations of TNF-α (P < .001) and IL-1β (P < .01) were statistically significantly increased in individuals in group 1 as compared with group 2. A significant positive correlations were found between TNF-α levels and BOP (P = .024) and PIBL (P = .016); and significant positive correlation was found between IL-1β and PIBL (P = .018) in group 1, respectively. Clinical and radiographic peri-implant parameters are compromised among vaping individuals. Increased levels of proinflammatory cytokines in peri-implant sulcular fluid may suggest greater local inflammatory response in vaping individuals for peri-implant inflammation. © 2018 Wiley Periodicals, Inc.

To investigate the clinical effect of Gushen Antai pills and progesterone in the treatment of threatened abortion, in order to provide references for early clinical intervention with threatened abortion. The 112 cases of patients with threatened abortion were randomly divided into the control group and the observation group. 56 cases in each group. Patients in the control group was injected with progesterone, the observation group was treated with Gushen Antai pills in addition to the therapy of the control group. Both groups were treated by drugs for two weeks. Their venous bloods (5 mL) were collected before treatment and in 1, 2 weeks after treatment to determine serum levels of β-HCG, P, E2 and CA125. The differences between the two groups after treatment were compared. The total effective rate of the control group and the observation group were 79% and 91.9% respectively, with a statistically significant difference between the two groups (P＜0.05). Two weeks after the treatment, the serum levels of P and E2 in the observation group were significantly higher than before treatment, but the serum CA125 levels decreased significantly after treatment (P<0.05). These indicators showed statistically significant difference compared with that of the control group (P<0.05). After treatment, the serum β-HCG levels of the two groups were significantly higher than before treatment (P<0.05), but there was no statistically significant difference between the two groups. Gushen Antai pills and progesterone had a better clinical curative effect in treatment threatened abortion, which could significantly raise serum β-HCG, P and E2, reduce serum CA125 and increase the tocolysis efficiency, and so it was worth promoted in clinic.

Obesity is a common comorbidity in schizophrenia. Few studies have addressed obesity in Chinese schizophrenia patients. The aims of this current study were to evaluate the prevalence, risk factors and clinical correlates of obesity in Chinese patients with schizophrenia. A total of 206 patients were recruited from a hospital in Beijing. Their clinical and anthropometric data together with plasma glucose and lipid parameters were collected. Positive and Negative Syndrome Scale (PANSS) was rated for all patients. Overall, 43 (20.9%) patients were obese and 67 (32.5%) were overweight. The obese patients had significantly higher glucose levels, triglyceride levels than non-obese patients. Females and patients with type 2 diabetes mellitus had increased risk for obesity. Correlation analysis showed that BMI was associated with sex, education levels, negative symptoms, total PANSS score, triglyceride levels and type 2 diabetes mellitus. Further stepwise regression analysis showed that sex, type 2 diabetes, education level, triglyceride and amount of smoking/day were significant predictors for obesity. Our study showed that the prevalence of obesity in Chinese patients with schizophrenia is higher than that in the general population. Some demographic and clinical variables are risk factors for obesity in schizophrenia. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

Background Cervical total disc replacement (TDR) is an increasingly accepted procedure for the treatment of symptomatic cervical degenerative disc disease. Multiple Level I evidence clinical trials have established cervical TDR to be a safe and effective procedure in the short-term. The objective of this study is to provide a long-term assessment of TDR versus anterior discectomy and fusion for the treatment of one- and two-level disc disease. Methods This study was a continuation of a prospective, multicenter, randomized, US FDA IDE clinical trial comparing cervical TDR with the Mobi-C© Cervical Disc versus ACDF through 7 years follow-up. Inclusion criteria included a diagnosis of symptomatic cervical degenerative disc disease at one or two cervical levels. TDR patients were treated using a Mobi-C© artificial disc (Zimmer Biomet, Austin TX, USA). ACDF with allograft and anterior plate was used as a control treatment. Outcome measures were collected preoperatively and postoperatively at 6 weeks, at 3, 6, 12, 18 months, annually through 60 months, and at 84 months. Measured outcomes included Overall success, Neck Disability Index (NDI), VAS neck and arm pain, segmental range of motion (ROM), patient satisfaction, SF-12 MCS/PCS, major complications, and subsequent surgery rate. The primary endpoint was an FDA composite definition of success comprising clinical improvement and an absence of major complications and secondary surgery events. Results A total of 599 patients were enrolled and treated, with 164 treated with one-level TDR, 225 treated with two-level TDR, 81 treated with one-level ACDF, and 105 treated with two-level ACDF. At seven years, follow-up rates ranged from 73.5% to 84.4% (overall 80.2%). The overall success rates of two level TDR and ACDF patients were 60.8% and 34.2%, respectively (p<0.0001). The overall success rates of one level TDR and ACDF patients were 55.2% and 50%, respectively (p>0.05). Both the single and two level TDR and ACDF groups showed significant improvement from baseline NDI scores, VAS neck and arm pain scores, and SF-12 MCS/PCS scores (p<0.0001). In the single level cohort, there was an increased percentage of TDR patients who reported themselves as “very satisfied” (TDR 90.9% vs ACDF 77.8%; p= 0.028). There was a lower rate of adjacent level secondary surgery in the single level TDR patients (3.7%) versus the ACDF patients (13.6%; p = 0.007). In the two level TDR group, the NDI success rate was significantly greater in the TDR group (TDR: 79.0% vs. ACDF: 58.0%; p=0.001). There was significantly more improvement in NDI change score at 7 years in the TDR patients versus ACDF. The TDR group had a significantly higher rate of patients who were “very satisfied” with their treatment compared to the ACDF group (TDR: 85.9% vs. ACDF: 73.9%). The rate of subsequent surgery at the index level was significantly lower in the TDR group compared to the ACDF group (TDR: 4.4% vs. ACDF: 16.2%; p=0.001). The rate of adjacent level secondary surgery was significantly lower in the two level TDR (4.4%) patients compared to the ACDF (11.3%; p=0.03) patients. In both single and two level cohorts, the percentage of patients with worse NDI (2.5%-3.8% of two level surgeries and 1.2%-2.5% of single level surgeries) or worse neck pain (5%-6.8% of the two level surgeries and 1.3% - 3.8% of the single level surgeries) was strikingly low in both groups but trended lower in the TDR patients. Conclusions At seven years, the composite success analysis demonstrated clinical superiority of two level TDR over ACDF and non-inferiority of single level TDR versus ACDF. There were lower rates of secondary surgery and higher adjacent level disc survivorship in both groups. Both surgeries were remarkably effective in alleviating pain relative to baseline and the rate of patients with worse disability or neck pain was surprisingly low. Overall, greater than 95% of patients (from both groups) who underwent TDR and 88% of patients who underwent ACDF were “very satisfied” at seven years. The differences in clinical effectiveness of TDR versus ACDF becomes more apparent as treatment increases from one to two levels, indicating a significant benefit for TDR over ACDF for two-level procedures. Ethical Standards The Mobi-C Clinical Trial (ClinicalTrials.gov registration number: NCT00389597) was conducted at 24 sites in the US and was approved by the Institutional Review Board, Research Ethics Committee, or local equivalent of each participating site.

Thirty-seven people of different dietary habits—vegans, ovolactovegetarians, whole-food omnivores and average omnivores—were studied using nine-day weighed food intakes, clinical and laboratory assessments, standard psychology questionnaires, measurements of urinary cortisol and catecholamine levels and questionnaires on life-style and health factors. The vegan diet most clearly approximated current thinking on diet, as expressed in the NACNE Report, but was deficient in vitamin D, riboflavin, and vitamin B12. Cholesterol levels were significantly higher in both diet and serum in all groups compared with the vegans. There was no significant difference in social background, money spent on food, exercise, smoking, stress levels or psychological parameters between groups. PMID:2993600

Human Genome discovery research has set the pace for Post-Genomic Discovery Research. While post-genomic fields focused at the molecular level are intensively pursued, little effort is being deployed in the later stages of molecular medicine discovery research, such as clinical-genomics. The objective of this study is to demonstrate the relevance and significance of integrating mainstream clinical informatics decision support systems to current bioinformatics genomic discovery science. This paper is a feasibility study of an original model enabling novel "in-silico" clinical-genomic discovery science and that demonstrates its feasibility. This model is designed to mediate queries among clinical and genomic knowledge bases with relevant bioinformatic analytic tools (e.g. gene clustering). Briefly, trait-disease-gene relationships were successfully illustrated using QMR, OMIM, SNOMED-RT, GeneCluster and TreeView. The analyses were visualized as two-dimensional dendrograms of clinical observations clustered around genes. To our knowledge, this is the first study using knowledge bases of clinical decision support systems for genomic discovery. Although this study is a proof of principle, it provides a framework for the development of clinical decision-support-system driven, high-throughput clinical-genomic technologies which could potentially unveil significant high-level functions of genes.

The relationship between hyperuricemia and hypertensive disorders is well established; however, until today, the role of uric acid in the clinical course of severe preeclampsia has not been elucidated. Some recent studies suggest that at the time of presentation, subjects with severe preeclampsia frequently have significantly elevated serum uric acid levels, and that the degree of elevation correlates with the severity of the maternal syndrome and fetal morbimortality. In this chapter, we present our workgroup experience. In 2016, we designed a prospective, cross-sectional comparative study. A sample of 200 patients - 100 with severe preeclampsia and 100 with normotensive pregnancy - was obtained. Plasmatic uric acid levels were recorded in units of mg/dL as clinical variables and as laboratory and fetal growth data. We considered uric acid equal to or more than 6.0 mg/dL as the elevated level. To relate the significance of elevated uric acid levels with variables, chi-square tests and Mann-Whitney U test were applied. Any p value equal or <0.05 was accepted as significant. We found significant difference (p = 0.05) between serum uric acid levels among both groups. In comparison with the healthy patients, patients with severe preeclampsia and uric acid greater than 6 mg/dl presented significant differences in relation to fetal complications and maternal laboratory and clinical variables. Our conclusion is that values equal to or greater than 6 mg/dL of serum uric acid in patients with severe preeclampsia may be a valuable biomarker for preeclampsia and an association with the presence of adverse fetal and maternal effects. © 2018 S.

To investigate the clinical implication of peak body temperature, peripheral blood white blood cell (WBC) count, and serum C-reactive protein (CRP) level in febrile symptoms among geriatric hospitalized patients, they were analyzed in 968 febrile episodes obtained from 433 hospitalized patients in the referred hospital. Episodes of one day duration were most frequent (41.6%). WBC count was elevated over 8000/microliters in 475 episodes (49.1%) and CRP exceeded 1.0 mg/dl in 770 episodes (79.5%). Frequency of WBC elevation decreased and frequency of CRP elevation increased according to the time course. The mean value of CRP increased significantly according to the time course. The frequency of WBC count increase and CRP elevation and their averages correlated to the peak body temperature. The peak body temperature displayed the most striking correlation to the length of febrile episodes among three clinical indicators, peak body temperature, WBC count, and CRP level. These results indicate that the elevation of WBC count and/or CRP level is frequent in geriatric patients with febrile symptoms. Peak body temperature may serve as a clinical indicator of the severy of the febrile disease occurring in geriatric patients.

This study aimed to develop a suitable instrument for a comprehensive quantitative and qualitative assessment of perceived psychosocial impact, levels of stress and learning effect in undergraduate dental students during the transition from pre-clinical to clinical education. These findings might improve curricular structures and didactic organisation during this period. At the beginning of their first clinical year, undergraduate dental students were asked to complete an anonymous forty-item questionnaire. Two hundred and seventy-six undergraduate dental students were willing to participate and completed the questionnaire and participated during the years 2011-2016. The response rate was between 45% and 96%. Correlational analysis (Spearman-Rho) in the field of psychosocial impact showed the dental teacher to be the most important multiplier of students' feelings. If the students feel that their teacher acts cooperatively, positive items increase and negative items decrease significantly (P < .0001). Also, students who report high levels of stress are affected significantly in their psychosocial interaction (P < .0001). Wilcoxon test yielded highest levels of stress in endodontology during the first weeks (P < .0001). During the same period, the greatest learning increment was seen for diagnostics and caries excavation. In conclusion, teaching of undergraduate dental students during the transition period from pre-clinical to clinical education can be positively influenced by a supportive learning environment and by specific chronological modifications in the curriculum. Students should start their clinical training with diagnostics, preventive dentistry and initial periodontal treatment. Due to high levels of perceived stress, endodontology should be introduced later in the clinical curriculum. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Background: Percutaneous biliary drainage is an accepted palliative treatment for malignant biliary obstruction. Purpose: To assess the effect on quality of life (QOL) and bilirubin level reduction in patients with inoperable malignant biliary obstruction treated by unilobar or bilobar percutaneous transhepatic biliary drainage (PTBD). Materials and Methods: Over a period of 2 years, 49 patients (age range, 22–75 years) of inoperable malignant biliary obstruction were treated by PTBD. Technical and clinical success rates, QOL, patency rates, survival rates, and complications were recorded. Clinical success rates, QOL, and bilirubin reduction were compared in patients treated with complete (n = 21) versus partial (n = 28) liver parenchyma drainage. QOL before and 1 month after biliary drainage were analyzed retrospectively between these two groups. Results: Biliary drainage was successful in all 49 patients, with an overall significant reduction of the postintervention bilirubin levels (P < 0.001) resulting in overall clinical success rate of 89.97%. Clinical success rates were similar in patients treated with whole-liver drainage versus partial-liver drainage. Mean serum bilirubin level before PTBD was 19.85 mg/dl and after the procedure at 1 month was 6.02 mg/dl. The mean baseline functional score was 39.35, symptom scale score was 59.55, and global health score was 27.45. At 1 month, mean functional score was 61.25, symptom scale score was 36.0 4, and global health score was 56.33, with overall significant improvement in QOL (<0.001). There was a statistically significant difference in the improvement of the QOL scores (P = 0.002), among patients who achieved clinical success, compared with those patients who did not achieve clinical success at 1 month. We did not find any significant difference in the QOL scores in patients according to the amount of liver drained (unilateral or bilateral drainage), the type of internalization used (ring biliary or stent). Overall, minor and major complications rates were 14.3% and 8.1%, respectively. Conclusion: Percutaneous biliary drainage provides good palliation of malignant obstructive jaundice. Partial-liver drainage achieved results as good as those after complete liver drainage with significant improvements in QOL and reduction of the bilirubin level. PMID:26962281

Multiple myeloma (MM) is characterized by the enhanced production of the same monoclonal immunoglobulin (M-Ig or M protein). Techniques such as serum protein electrophoresis and nephelometry are routinely used to quantify levels of this protein in the serum of MM patients. However, these methods are not without their shortcomings and problems accurately quantifying M proteins remain. Precise quantification of the types and levels of M-Ig present is critical to monitoring patient response to therapy. In this study, we investigated the ability of the HevyLite (HLC) immunoassay to correlate with clinical status based on levels of involved and uninvolved antibodies. In our cohort of MM patients, we observed that significantly higher ratios and greater differences of involved HLC levels compared to uninvolved HLC levels correlated with a worse clinical status. Similarly, higher absolute levels of involved HLC antibodies and lower levels of uninvolved HLC antibodies also correlated with a worse clinical status and a shorter progression-free survival. These findings suggest that the HLC assay is a useful and a promising tool for determining the clinical status and survival time for patients with multiple myeloma. © 2016 John Wiley & Sons Ltd.

Objective Salivary mucin and amylase levels are increased in patients with chronic periodontitis (CP). Due to the fact that aggressive periodontitis (AgP) not only differs from chronic periodontitis in terms of its clinical manifestation, the aim of this study was to compare salivary mucin and amylase levels and their relation to the clinical parameters of patients with aggressive periodontitis with that of patients with chronic periodontitis. Material and Methods Eighty subjects were divided into two groups: 20 patients with AgP and their 20 matched controls and 20 patients with CP and their 20 matched controls, based on clinical attachment loss (CAL), probing pocket depth (PPD) and bleeding on probing (BOP). Whole unstimulated saliva was obtained and mucin, amylase and protein were determined by colorimetric methods. Pearson’s correlation analysis was used to determine the relationship between salivary mucin, amylase and protein levels and the clinical parameters. Results Salivary mucin, amylase and protein levels were increased in patients with AgP and CP but there were no differences between them or between control groups. Pearson’s correlation analysis, determined in the entire subjects studied, showed a positive and significant correlation of mucin, amylase and proteins with CAL and PPD and a negative correlation with the flow rate. When Pearson’s correlation analysis was carried out in each group separately, Fisher’s z transformation showed no significant difference between both groups. Conclusion Comparison of the salivary levels of mucin, amylase and protein and their relationship with clinical parameters of AgP patients with that of CP patients revealed no differences between both groups.

In the United States, breast cancer is the second leading cause of cancer death in women. Over the past 20 years, breast cancer incidence and mortality rates increased rapidly in developing regions. We aimed to identify the gene mutation patterns that associated with the clinical patterns, including survival status, histo-pathological classes and so forth, of breast cancer. We retrieved 1098 cases of the clinical information, and level-3 legacy data of mRNA expression level, protein expression data and mutation files from GDC data portal. The genes with mutation significance were obtained. We studied the impacts of mutation types on the expression levels of mRNA and protein. Different statistics methods were used to calculate the correlation between the mutation types and the expression data or histo-clinical measures. There were 24 genes with mutation significance identified. The most mutated genes were selected to study the role of specific mutations played on the patients with breast cancer. One interesting finding was the missense mutations on TP53 were related with high expression levels of mRNA and protein. The missense mutations on TP53 were highly related with the morphology, race, ER status, PR status and HER2 Status, while the truncated mutations were only related with the morphology, ER status and PR status. The missense mutation on PIK3CA was highly associated with the morphology, race, ER status and PR status. The mutants with different mutants and the wild type of the most mutated genes had different impacts on the histo-clinical measures that might help personalized therapy.

Although stand-alone cages were advocated to be superior to plate-cage construct (PCC) because of comparable clinical outcomes and fewer plate-related complications, cage dislocation and subsidence were frequently mentioned in multilevel fusion. There are some concerns about whether these issues can be effectively prevented in multilevel anterior cervical discectomy and fusion (ACDF) by stand-alone anchored spacer (SAAS). The aim was to compare clinical outcomes, radiologic parameters, and complications of PCC and SAAS in the treatment of three-level cervical spondylotic myelopathy (CSM). This was a retrospective comparative study. A total of 38 consecutive patients with three-level CSM (ACDF with PCC, 20 patients; ACDF with SAAS, 18 patients) were reviewed. Clinical outcomes were assessed using Japanese Orthopaedic Association and Neck Disability Index. The radiologic evaluations included cervical alignment (CA), segmental angle (SA), postoperative curvature loss (PCL), and incidence of subsidence. All the aforementioned parameters were compared before and after surgery between two groups. Besides, the aforementioned results were also compared between the two groups. The complications were also recorded. The mean follow-up period was 30.3 months. No significant differences were observed in clinical outcomes between the two groups (p>.05). Additionally, no significant differences existed in fusion rate between the two groups. There were significant differences in PCL of SA and CA and correction of SA between the two groups (p<.05). Besides, the incidence of subsidence (9 of 54 levels, 16.7%) was recorded in the SAAS group, and the potential of SAAS to reduce the incidence of postoperative dysphagia was not proven. No other complications were observed in this study. In the surgical treatment of three-level CSM, PCC is superior to SAAS in correction and maintenance of SA and avoiding cage subsidence, although the technique of ACDF with SAAS yielded encouraging clinical outcomes and high fusion rate.

Clinical and biochemical markers of periodontal disease have been used for precise objective diagnosis of periodontal inflammation. Interleukin 1beta (IL-1beta) and prostaglandin E2 (PGE2), inflammatory factors, levels in gingival crevicular fluid (GCF) of patients with periodontal disease are elevated and have been studied as biochemical markers. The levels of calprotectin, a leukocyte protein, in body fluids of patients with some inflammatory diseases are raised. Recently, we detected calprotectin in GCF and its concentrations in periodontal pockets were higher than those in healthy gingival crevices. In this study, we investigated the correlations between GCF calprotectin levels and clinical indicators (probing depth and bleeding on probing, BOP), and the IL-1beta or PGE2 levels in GCE Probing depth and BOP at 130 sites of 110 subjects with periodontal or other oral diseases were examined, then GCF samples were collected and their calprotectin, IL-1beta and PGE2 were determined by ELISA. The calprotectin level correlated positively with the probing depth and was significantly higher at BOP-positive than BOP-negative sites. There were significant, positive correlations between the calprotectin and IL-1beta or PGE2 concentrations. These results indicate that the calprotectin level in GCF correlates well with clinical and biochemical markers of periodontal disease and suggest that calprotectin may be useful for evaluating the extent of periodontal inflammation.

Cancer patients often present altered serum lipid profile including changes of HDL cholesterol level. The aim of our work was to evaluate serum level of HDL cholesterol in patients with squamous cell and small cell lung cancer and its dependence on histological type and clinical stage of lung cancer. Fasting serum level of HDL cholesterol was analysed in 135 patients with newly diagnosed lung cancer and compared to a control group of healthy men. All lung cancer patients, as well as subgroups of squamous cell and small cell lung cancer had statistically significantly lower HDL cholesterol concentration than controls. There were no statistically significant differences of HDL cholesterol level between the histological types or between clinical stages of each histological type of lung cancer.

Inflammation may play a role in the accelerated physical aging reported in schizophrenia, though biomarker findings and associations with demographic and clinical factors are inconsistent. In a cross-sectional, case-control design, 95 outpatients with schizophrenia (mean age ± SD: 48.1 ± 10.2 years) and 95 demographically comparable healthy comparison subjects (HCs) (mean age ± SD: 48.1 ± 12.1 years) were studied. Sociodemographic and clinical data were collected, and plasma levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interferon-γ (IFN-γ) were assayed. The authors compared cytokine levels, examined demographic and clinical associations, and adjusted for relevant variables with linear models. Individuals with schizophrenia had higher levels of TNF-α and IL-6 but not IFN-γ than HCs. Age was not related to cytokine levels, and age relationships did not differ between diagnostic groups. Women had higher levels of IL-6. TNF-α and IL-6 levels were significantly correlated with depressive symptoms, and adjustment for depression reduced the group effect for both. Within the HCs, TNF-α levels were associated with physical comorbidity and body mass index. IL-6 levels were significantly correlated with body mass index and within schizophrenia patients, with worse mental and physical well-being. Accounting for physical morbidity and mental well-being reduced group differences in TNF-α and IL-6 levels, respectively. Worse positive symptoms were associated with higher IL-6 levels. Higher TNF-α and IL-6 levels in schizophrenia patients were associated with depression, physical comorbidity, and mental well-being. Further longitudinal studies are warranted to assess inflammation as a potential treatment target for a subgroup of schizophrenia. Copyright © 2017 American Association for Geriatric Psychiatry.

This study evaluated whether harp therapy reduces levels of stress and improves clinical outcomes in patients undergoing embryo transfer. This prospective randomized trial enrolled 181 women undergoing embryo transfer, who were randomized to harp therapy during embryo transfer or standard treatment. Patients underwent standardized psychological testing and physiologic assessment of stress. The study was conducted in a reproductive medicine practice. No statistically significant differences were found in the heart and respiratory rates, nor was there a significant difference in event-based anxiety at baseline. Harp therapy had a significantly larger decrease in state anxiety from pre- to post-embryo transfer. Clinical pregnancy was 53% versus 48% for the harp therapy and standard treatment groups, respectively. Harp therapy decreases state, or event-based, anxiety, significantly lowering state scores posttransfer and having a positive effect on acute levels of stress. There was an increased pregnancy rate, but larger sample sizes are needed to evaluate whether harp therapy has an effect on clinical outcomes.

Background: Comparative efficacy of different pharmacist based interventions on glycemic control of type 2 diabetes patients is unclear. This review aimed to evaluate and compare the efficacy of different pharmacist based interventions on clinical outcomes of type 2 diabetes patients. Methods: A systematic search was conducted across five databases from date of database inception to September 2017. All randomized clinical trials evaluating the efficacy of pharmacist based interventions on type 2 diabetes patients were included for network meta-analysis (NMA). The protocol is available with PROSPERO (CRD42017078854). Results: A total of 43 studies, involving 6259 type 2 diabetes patients, were included. NMA demonstrated that all interventions significantly lowered glycosylated hemoglobin (HbA1c) levels compared to usual care, but there was no statistical evidence from this study that one intervention was significantly better than the other for reducing HbA1c levels. Pharmacist based diabetes education plus pharmaceutical care showed maximum efficacy for reducing HbA1c levels [-0.86, 95% CI -0.983, -0.727; p < 0.001]. Pharmacist based diabetes education plus pharmaceutical care was observed to be statistically significant in lowering levels of systolic blood pressure [-4.94; 95%CI -8.65, -1.23] and triglycerides levels [-0.26, 95%CI -0.51, -0.01], as compared to the interventions which involved diabetes education by pharmacist, and for body mass index (BMI) [-0.57; 95%CI -1.25, -0.12] in comparison to diabetes education by health care team involving pharmacist as member. Conclusion: The findings of this review demonstrate that all interventions had a significantly positive effect on HbA1c, but there was no statistical evidence from this study that one intervention was significantly better than the other for achieving glycemic control.Pharmacist based diabetes education plus pharmaceutical care showed maximum efficacy on HbA1c and rest of the clinical outcomes.

To investigate possible relationships among oral mucosal epithelial MUC1 expression, salivary female gonadal hormones and stress markers, and clinical characteristics in patients with burning mouth syndrome (BMS). Thirty post-menopausal female patients with BMS (60.0±5.0 years) were included. Clinical and psychological evaluations were performed and the expression level of oral mucosal epithelial MUC1 was analyzed. The levels of cortisol, dehydroepiandrosterone (DHEA), 17β-estradiol, progesterone, chromogranin A, and blood contamination were determined from unstimulated whole saliva (UWS) and stimulated whole saliva (SWS) samples. Salivary progesterone level had significant positive correlations with oral mucosal epithelial MUC1 expression level and with salivary cortisol and DHEA levels. The salivary level of 17β-estradiol showed significant positive correlations with period of symptom duration, severity of effects of oral complaints on daily life, and results from psychological evaluations. Cortisol level in UWS and cortisol/DHEA ratio in UWS and SWS had negative correlations with severity of oral burning sensation significantly. The severity of taste disturbance had positive correlations with results from psychometry significantly. Dysregulated psychoendocrinological interactions might affect oral mucosal MUC1 expression and severity of oral burning sensation in post-menopausal BMS patients. Copyright © 2017 Elsevier Ltd.

During investigations of the phenotypic diversity of hemoglobin (Hb) E β thalassemia, a patient was encountered with persistently high levels of methemoglobin associated with a left-shift in the oxygen dissociation curve, profound ascorbate deficiency, and clinical features of scurvy; these abnormalities were corrected by treatment with vitamin C. Studies of erythropoietin production before and after treatment suggested that, as in an ascorbate-deficient murine model, the human hypoxia induction factor pathway is not totally dependent on ascorbate levels. A follow-up study of 45 patients with HbE β thalassemia showed that methemoglobin levels were significantly increased and that there was also a significant reduction in plasma ascorbate levels. Haptoglobin levels were significantly reduced, and the high frequency of the 2.2 haptoglobin genotype may place an additional pressure on ascorbate as a free-radical scavenger in this population. There was, in addition, a highly significant correlation between methemoglobin levels, splenectomy, and factors that modify the degree of globin-chain imbalance. Because methemoglobin levels are modified by several mechanisms and may play a role in both adaptation to anemia and vascular damage, there is a strong case for its further study in other forms of thalassemia and sickle-cell anemia, particularly when splenic function is defective.

Background For blunt trauma patients who have failed the NEXUS low-risk criteria, the adequacy of CT as the definitive imaging modality for clearance remains controversial. The purpose of this study was to prospectively evaluate the accuracy of CT for the detection of clinically significant C-spine injury. Methods Prospective multicenter observational study (09/2013-03/2015), at 18 North American Trauma Centers. All adult (≥18yo) blunt trauma patients underwent a structured clinical examination. NEXUS failures underwent a CT of the C-spine with clinical follow up to discharge. The primary outcome measure was sensitivity and specificity of CT for clinically significant injuries requiring surgical stabilization, halo or cervical-thoracic orthotic (CTO) placement using the gold standard of final diagnosis at the time of discharge, incorporating all imaging and operative findings. Results 10,765 patients met inclusion criteria, 489 (4.5%) were excluded (previous spinal instrumentation or outside hospital transfer). 10,276 patients [4,660 (45.3%) unevaluable/distracting injuries, 5,040 (49.0%) midline C-spine tenderness, 576 (5.6%) neurologic symptoms] were prospectively enrolled: mean age 48.1yo (range 18-110), SBP 138 (SD 26), median GCS 15 (IQR 14,15), ISS 9 (IQR 4,16). Overall, 198 (1.9%) had a clinically significant C-spine injury requiring surgery [153 (1.5%)] or halo [25 (0.2%)] or CTO [20 (0.2%)]. The sensitivity and specificity for clinically significant injury was 98.5% and 91.0% with a NPV of 99.97%. There were 3 (0.03%) false negative CT scans that missed a clinically significant injury, all had a focal neurologic abnormality on their index clinical examination consistent with central cord syndrome and 2 of 3 had severe degenerative disease. Conclusions For patients requiring acute imaging for their C-spine after blunt trauma, CT was effective for ruling out clinically significant injury with a sensitivity of 98.5%. For patients with an abnormal neurologic exam as the trigger for imaging, there is a small but clinically significant incidence of a missed injury and further imaging with MRI is warranted.

This study aimed to evaluate postural awareness and changes in posture and flexibility of students who took Clinical Pilates class as an elective course at the undergraduate level. The study conducted from 2013-2016 included 98 students who took Clinical Pilates class at the Department of Physical Therapy and Rehabilitation, School of Health Sciences, Istanbul Medipol University, Turkey. The flexibility levels of the study participants were measured before and after the Clinical Pilates education using finger-to-floor test and modified Schober's test. Observational posture analysis and postural awareness were recorded using the scale prepared by the researchers. The post-education evaluations showed that postural distortions were fixed, and a significant increase in the postural awareness of the students was observed compared with the pre-education period. The results of both modified Schober's test and finger-to-floor test, which were used to measure the flexibility levels, showed a statistically significant increase in post-education scores compared with those of the pre-education period. This study showed that the Clinical Pilates course increased postural awareness and flexibility of physical therapy students and fixed postural distortions. Thus, the inclusion of Clinical Pilates class in the undergraduate education is considered to be important.

Complications following intestinal and urinary diversion (OSTOMY) surgery are a significant problem for many individuals. Patient characteristics or risk factors have been associated with the development of ostomy complications, but research in this area is limited. To examine the demographic and clinical characteristics of new ostomy patients. Descriptive, cross-sectional study. A convenience sample of 144 new ostomy patients was recruited from a large midwest urban level i trauma teaching hospital system. A descriptive, cross-sectional design was used to examine the demographic and clinical characteristics in persons with a new ostomy. demographic and clinical characteristics included were age, gender, disposition, diagnosis, ostomy type, type of procedure (emergent or elective), stoma type (temporary or permanent), technique of stoma creation (loop or end), stoma site marked preoperatively, body type, stoma height, and complicating factors. Data were collected through a medical record review and direct observation by the WOC nurse. Significant differences were found among demographic and clinical characteristics and ostomy type and disposition. Age, type of procedure, reason for surgery, stoma type, stoma site marking, and complicating factors were significantly different by ostomy type. The majority of stomas were not marked preoperatively (67%). Sixty-eight percent of persons with a stoma above skin level versus 38% with a stoma below skin level were discharged to their home. Statistically significant relationships were found among disposition and type of procedure (P = .036), stoma height (P = .003), reason for surgery (P = .000), and age (P = .005). This study provides additional information regarding specific patient characteristics (demographic and clinical) and their relationship to ostomy type and disposition.

Oxidative stress is involved in a variety of diseases. Prospective studies investigating the relationship between oxidative stress biomarkers and the status and development of colorectal cancer (CRC) are scarce; previous studies have failed to establish a relationship between the serum total oxidant/antioxidant status and CRC. Therefore, we compared the total serum oxidant/antioxidant levels of CRC patients and healthy subjects, and analyzed their clinical significance in the CRC. Fasting blood samples from 132 CRC patients and 64 healthy subjects were collected. Oxidative stress parameters, including total oxidant status (TOS) and total antioxidant status (TAS), were measured, and the oxidative stress index (OSI) was calculated. The TOS and OSI levels increased significantly (P<0.001) and the TAS level significantly decreased (P<0.001) in the CRC group compared to those in the healthy control group. Oxidative stress parameters differed significantly depending on the patient’s smoking and drinking status (P<0.05). The preoperative and postoperative levels of TOS, TAS, and OSI did not differ significantly between primary sites (colon/rectum) and clinical stages (P>0.05).However, the levels of TOS, TAS, and OSI were significantly different between patients with no metastasis and those with metastases to two organs (P<0.05) Finally, the parameters are affected by smoking and drinking, and subsequent research should be conducted excluding the relevant influencing factors.

To evaluate levels of spirituality and hope in patients with diabetic foot ulcers (DFUs) according to sociodemographic factors. This was a primary, prospective, descriptive, analytical, and clinical study. Questionnaires assessing sociodemographic and clinical characteristics of the patients, the Spirituality Self-rating Scale (SSRS), and the Herth Hope Index (HHI) were administered to all participants. University-affiliated skilled nursing center and outpatient wound care clinic in Pouso Alegre, Brazil. Fifty adult patients with DFUs participated in the study. Patients with ischemic diabetic foot and mixed ulcers were excluded from the study. On average, patients with DFUs had low levels of spirituality (mean SSRS score, 12.6) and low hope for cure (mean HHI, 16.5). Patients younger than 60 years reported significantly lower levels of spirituality (mean SSRS scores, 11.0), and those older than 70 years had significantly lower hope for cure (mean HHI, 12.5) than other age groups (P = .040). Level of spirituality was significantly lower among women (P = .015) and those living with an ulcer for more than 2 years, who also reported significantly lower hope for cure (P = .029) compared with patients having an ulcer for less than 2 years. On average, patients with DFUs, especially women and older adults, had a low sense of hope and spirituality. Except for gender, age, and ulcer duration, other sociodemographic and ulcer characteristics had no significant effect on the study population's spirituality and hope.

Background Fibromyalgia (FM) is a chronic pain syndrome with unknown etiology and a wide spectrum of symptoms such as allodynia, debilitating fatigue, joint stiffness and migraine. Recent studies have shown some evidences demonstrating that oxidative stress is associated to clinical symptoms in FM of fibromyalgia. We examined oxidative stress and bioenergetic status in blood mononuclear cells (BMCs) and its association to headache symptoms in FM patients. The effects of oral coenzyme Q10 (CoQ10) supplementation on biochemical markers and clinical improvement were also evaluated. Methods We studied 20 FM patients and 15 healthy controls. Clinical parameters were evaluated using the Fibromyalgia Impact Questionnaire (FIQ), visual analogues scales (VAS), and the Headache Impact Test (HIT-6). Oxidative stress was determined by measuring CoQ10, catalase and lipid peroxidation (LPO) levels in BMCs. Bioenergetic status was assessed by measuring ATP levels in BMCs. Results We found decreased CoQ10, catalase and ATP levels in BMCs from FM patients as compared to normal control (P<0.05 and P<0.001, respectively) We also found increased level of LPO in BMCs from FM patients as compared to normal control (P<0.001). Significant negative correlations between CoQ10 or catalase levels in BMCs and headache parameters were observed (r = −0.59, P<0.05; r = −0.68, P<0.05, respectively). Furthermore, LPO levels showed a significant positive correlation with HIT-6 (r = 0.33, P<0.05). Oral CoQ10 supplementation restored biochemical parameters and induced a significant improvement in clinical and headache symptoms (P<0.001). Discussion The results of this study suggest a role for mitochondrial dysfunction and oxidative stress in the headache symptoms associated with FM. CoQ10 supplementation should be examined in a larger placebo controlled trial as a possible treatment in FM. PMID:22532869

Major depressive disorder (MDD) significantly impacts performance of both work- and nonwork-related routine daily activities. We have shown that work productivity is significantly impaired in employed MDD patients, but the extent of impairments in nonwork-related routine activities and its association with antidepressant treatment outcomes has not been established. Activity impairment was measured using the sixth item of Work Productivity and Activity Impairment Scale in the Combining Medications to Enhance Depression Outcomes (CO-MED) trial (n=665). Published norms were used to define activity impairment levels. The relationship between activity impairment and baseline sociodemographic and clinical characteristics was evaluated along with changes in activity impairment and its relationship with other clinical outcomes such as symptom severity, function, and side effect burden. Remission status at 3 and 7 months was predicted based on week 6 activity impairment level. Higher psychosocial and cognitive impairments and greater number of comorbid medical conditions were associated with greater activity impairment at baseline. Proportion of participants with severe activity impairment declined from 47.6% at baseline to 18.7% at 3 months, while mean activity impairment decreased from 57.1 at baseline to 32.8 at 3 months. During course of treatment, levels of activity impairment correlated most strongly with psychosocial function among measures of symptom severity, function, quality of life, and side effect burden. No or minimal activity impairment at week 6 was associated with two to three times higher rates of remission at 3 and 7 months as compared to moderate or severe activity impairment levels even after controlling for remission status at week 6 and select baseline variables. Depressed patients have high levels of nonwork-related activity impairment at baseline that improves significantly with treatment and independently predicts long-term clinical outcomes. Brief systematic assessment of activity impairment during the course of antidepressant treatment can help inform clinical decision-making.

No studies have monitored the levels of faecal calprotectin (FC) during mesalazine suppository therapy for proctitis in ulcerative colitis (UC). To evaluate the value of consecutive monitoring of FC in patients with UC during mesalazine suppository therapy. One hundred and sixty patients with active inflammation limited to the rectum were treated with mesalazine 1 g suppository once daily for 8 weeks. Patients who achieved clinical remission were advised to maintain the treatment, and were followed up for further 40 weeks. FC levels were measured every 8 weeks during the study. At week 8, 118 patients (74%) went into clinical remission, of whom 88 achieved endoscopic healing. The median FC level significantly decreased in patients with clinical and endoscopic remission (both P < 0.0001), while it did not change significantly in those without remission. Eighty (68%) of the 118 patients with remission continued the treatment. Twenty-four patients (30%) relapsed during the 40-week follow-up. In patients with clinical relapse, the median FC level elevated already 8 weeks before the diagnosis of relapse. In contrast, in patients who maintained remission it remained at a low level and did not significantly change during the follow-up. Elevated FC level (≥55 μg/g) was useful for the early diagnosis of relapse (88% sensitivity and 80% specificity). Faecal calprotectin may represent a useful biomarker for the assessment of disease activity in UC patients treated with mesalazine suppositories. Serial monitoring of faecal calprotectin appears to be valuable for the prediction and early diagnosis of relapse during maintenance therapy. © 2015 John Wiley & Sons Ltd.

The value of routine blood tests in malignant soft tissue tumors remains uncertain. To determine if these tests can be used for screening, the routine pretreatment blood test findings were retrospectively investigated in 359 patients with benign and malignant soft tissue tumors. Additionally, the prognostic potential of pretreatment blood abnormalities was evaluated in patients with soft tissue sarcomas. We compared clinical factors and blood tests findings between patients with benign and malignant soft tissue tumors using univariate and multivariate analysis. Subsequently, patients with malignant tumors were divided into two groups based on blood test reference values, and the prognostic significance of each parameter was evaluated. In the univariate analysis, age, tumor size, and tumor depth were significant clinical diagnostic factors. Significant increases in the granulocyte count, C-reactive protein (CRP) level, erythrocyte sedimentation rate (ESR), and γ-glutamyl transpeptidase (γ-GTP) levels were found in patients with malignant soft tissue tumors. Multiple logistic regression showed that tumor size and ESR were independent factors that predicted malignant soft tissue tumors. The Kaplan-Meier survival analysis revealed that granulocyte counts, γ-GTP levels, and CRP levels correlated significantly with overall survival. Thus, pretreatment routine blood tests are useful diagnostic and prognostic markers for diagnosing soft tissue sarcoma. © 2018 by the Association of Clinical Scientists, Inc.

Rationale Although soluble forms of the receptor for advanced glycation end products (RAGE) have been recently proposed as biomarkers in multiple acute or chronic diseases, few studies evaluated the influence of usual clinical and biological parameters, or of patient characteristics and comorbidities, on circulating levels of soluble RAGE in the intensive care unit (ICU) setting. Objectives To determine, among clinical and biological parameters that are usually recorded upon ICU admission, which variables, if any, could be associated with plasma levels of soluble RAGE. Methods Data for this ancillary study were prospectively obtained from adult patients with at least one ARDS risk factor upon ICU admission enrolled in a large multicenter observational study. At ICU admission, plasma levels of total soluble RAGE (sRAGE) and endogenous secretory (es)RAGE were measured by duplicate ELISA and baseline patient characteristics, comorbidities, and usual clinical and biological indices were recorded. After univariate analyses, significant variables were used in multivariate, multidimensional analyses. Measurements and Main Results 294 patients were included in this ancillary study, among whom 62% were admitted for medical reasons, including septic shock (11%), coma (11%), and pneumonia (6%). Although some variables were associated with plasma levels of RAGE soluble forms in univariate analysis, multidimensional analyses showed no significant association between admission parameters and baseline plasma sRAGE or esRAGE. Conclusions We found no obvious association between circulating levels of soluble RAGE and clinical and biological indices that are usually recorded upon ICU admission. This trial is registered with NCT02070536. PMID:29861796

Recent epidemiologic studies suggest that inflammation is the link between periodontal diseases and cardiovascular complications. This study aimed to evaluate the effects of non-surgical periodontal treatment on plasma levels of inflammatory markers (interleukin [IL]-6, C-reactive protein [CRP], and fibrinogen) in patients with severe periodontitis and refractory arterial hypertension. Twenty-two patients were examined and randomly divided into two groups. The test group was composed of 11 patients (mean age, 48.9 +/- 3.9 years) who received periodontal treatment, whereas the control group had 11 patients (mean age, 49.7 +/- 6.0 years) whose treatment was delayed for 3 months. Demographic and clinical periodontal data were collected, and blood tests were performed to measure the levels of IL-6, CRP, and fibrinogen at baseline and 3 months later. The clinical results showed that the mean percentages of sites with bleeding on probing, probing depth (PD) 4 to 5 mm, PD > or =6 mm, clinical attachment loss (CAL) 4 to 5 mm, and CAL > or =6 mm were significantly reduced in the test group 3 months after periodontal treatment. There were no significant differences between the data at baseline and 3 months in the control group. Periodontal treatment significantly reduced the blood levels of fibrinogen, CRP, and IL-6 in the test group. Non-surgical periodontal therapy was effective in improving periodontal clinical data and in reducing the plasma levels of IL-6, CRP, and fibrinogen in hypertensive patients with severe periodontitis.

The aim of the present study was to examine the clinical merits of joint application of β-sodium aescinate and mannitol for the treatment of early swelling of upper limb trauma after surgery. We verified whether the expression of serum aquaporin 1 (AQP-1) was involved in swelling mechanism. A total of 102 patients with swelling after upper limb trauma surgery were enrolled into the study and divided randomly into 3 groups (n=34 cases per group). Group A was treated with β-sodium aescinate; group B was treated with with mannitol and group C was treated with both β-sodium aescinate and mannitol. The expression level of AQP-1, and clinical effects and complications before and after treatment were compared§. The time of swelling subsidence in group C was significantly shorter than that of the other two groups and differences were statistically significant (P<0.05). The recovery ratio and total efficiency in group C were significantly higher than those in other two groups and differences were statistically significant (P<0.05). Three and seven days after treatment, the AQP-1 levels in group A and group C were decreased and AQP-1 level decreased further with time. Differences of comparison within groups were statistically significant (P<0.05), although the differences of comparison between the groups showed no statistical significance (P>0.05). We also compared the AQP-1 level in group B before and after treatment, and the differences were not statistically significant (P>0.05). When the complication incidence in the 3 groups was compared, no statistical significance was detected (P>0.05). We concluded that the joint use of β-sodium aescinate and mannitol in treating early swelling after upper limb trauma surgery produced satisfactory outcomes. This might be related to reduction of the AQP-1 level.

In recent years, treatment of substance use disorder has rekindled emphasis on recovery which, being a gradual process, starts with remoralization. In this study, we examine the level of demoralization throughout the treatment process for patients with comorbid substance dependence and psychiatric disorders. 217 patients with co-occurring disorders and 179 community-based individuals participated in this study. Demoralization was measured twice over one month as inpatient treatment happened. In contrast with the community sample, we found high levels of demoralization in the clinical cohort, with 86% of patients having demoralization scores above threshold. During the first month there was a statistically significant reduction in demoralization scores. However, clinically relevant change appeared limited, with only 3% of patients moving from dysfunctional to functional status in this naturalistic setting without targeted intervention aimed at remoralization. Although the level of demoralization is significantly improved during the first month of treatment, patients still remain strongly demoralized. Clinically relevant improvement is limited. It could be worthwhile to set up targeted interventions aimed at remoralization. Furthermore, we advocate for the assessment of demoralization in the clinical setting to monitor patients' treatment outcomes.

Bianchi, Andrea E; Bassetti, Achille

2009-04-01

The aim of this paper was to describe a new surgical technique designed to preserve interdental tissue in guided tissue regeneration. This procedure was created to specifically regenerate wide intrabony defects in the esthetic zone. Fourteen subjects with an intraosseous defect in the maxillary incisor region took part in this clinical study. The defects were treated with bioresorbable membranes in combination with a bovine bone mineral graft. At baseline and at 12 months after surgery, the following clinical parameters were measured: full-mouth plaque scores, full-mouth bleeding scores, probing pocket depths, clinical attachment levels, and gingival recession. A significant gain in clinical attachment level (4.57 +/- 0.65 mm) and a reduction in probing depths (5.14 +/- 0.95 mm) were reported 12 months after surgery. The surgical technique allowed complete flap closure in every treated site, resulting in significant improvement of the clinical parameters; thus, it appeared especially appropriate for the treatment of wide defects in the esthetic zone.

Insight has emerged as a significant treatment outcome predictor in adult obsessive-compulsive disorder (OCD), with some suggesting that OCD with poor insight represents a distinct clinical subtype. Despite its clinical relevance, limited data exist on insight in pediatric OCD patients. The present study investigated the relation between poor insight and clinical characteristics among children and adolescents with OCD (N=78, ages 6-20 years). Forty-five percent of the sample (n=35) was considered to have low levels of insight into their symptoms, as determined by clinician rating on item 11 of the Children's Yale-Brown Obsessive-Compulsive Scale. Pearson product-moment correlations showed a significant, inverse relation between insight and OCD severity. Relative to the high insight group, parents of patients with low insight reported higher levels of OCD-related impairment and family accommodation. These findings suggest that OCD with poor insight may represent a distinct clinical feature that may require more intensive and multimodal treatment approaches.

As little is known about the oxidant/antioxidant status in buffalo with ketosis, the present study was delineated to assess the oxidative stress level associated with clinical ketosis in water buffalo. A total of 91 parturient buffalo at smallholder farms were studied (61 suspected to be ketotic and 30 healthy). Clinical and biochemical investigations were carried out for each buffalo. Based on clinical findings and the level of beta-hydroxybutyrate (BHB), buffalo were allocated into ketotic (42), subclinical cases (19). Clinically, there was an association between clinical ketosis and anorexia (p<0.001), constipation (p<0.001), decreased milk yield (p<0.001), ruminal stasis (p<0.001), and loss of body condition (p<0.01). Biochemically, in clinical ketosis compared with subclinical and control cases, there was a significant increase (p<0.05) of BHB, malondialdehyde (MDA), nitric oxide (NO), aspartate aminotransferase (AST), L-alanine aminotransferase (ALT). However, there was a significant decrease of glucose, phosphorus, magnesium,total cholesterol and HDL-cholesterol. There was a positive correlation between BHB and MDA (r=0.433), BHB and NO (r=0.37), MDA and NO (r=0.515), and Glucose and phosphorus(r=0.521). However, there was a negative correlation between BHB and glucose (r= -0.341) and HDL and NO (r= -0.379). The result of the present study indicates that hyperketonemia in buffalo is associated with an increase of oxidative stress levels. Further studies need to be done on the efficacy of antioxidants as an ancillary treatment to relief the oxidative stress caused by ketosis.

Sufficient clinical data are not available on the effect of hypothyroidism on olfactory function in adults. In this study, we aimed to evaluate the olfactory function of adult patients diagnosed with primary hypothyroidism. Forty-five patients aged between 18 and 60 years who were diagnosed with clinical primary hypothyroidism and 45 healthy controls who had normal thyroid function tests were included in the study. Sniffin' Sticks olfactory test results of the 2 groups were compared. The relationships between thyroid function tests and olfactory parameters were evaluated. Odor threshold, identification, and discrimination scores of the hypothyroid group were significantly lower than those of the control group (p < 0.001). A significant positive correlation was detected between free triiodothyronine (FT3) levels and odor threshold, identification, and discrimination scores (p < 0.001). There was no significant relationship between thyroid-stimulating hormone (TSH) or free thyroxine (FT4) levels and olfactory parameters. Our study revealed diminished olfactory function in adults with hypothyroidism. FT3 levels were found to have a more significant relationship with olfactory parameters than TSH or FT4 levels. © 2015 ARS-AAOA, LLC.

To investigate the relationship between zonulin levels and clinical and laboratory parameters of childhood obesity. The study included obese children with a body mass index (BMI) >95 th percentile and healthy children who were of similar age and gender distribution. Clinical (BMI, waist circumferences, mid-arm circumference, triceps skinfold, percentage of body fat, systolic blood pressure, diastolic blood pressure) and biochemical (glucose, insulin, lipid levels, thyroid function tests, cortisol, zonulin and leptin levels) parameters were measured. A total of 43 obese subjects (23 males, mean age: 11.1±3.1 years) and 37 healthy subjects (18 males, mean age: 11.5±3.5 years) were included in this study. Obese children had significantly higher insulin, homeostasis model assessment of insulin resistance, triglyceride, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), zonulin and leptin levels than healthy children (p<0.05), while glucose levels were not different (p>0.05). Comparison of the obese children with and without insulin resistance showed no statistically significant differences for zonulin levels (p>0.05). Zonulin levels were found to negatively correlate with HDL-C and positively correlate with leptin levels, after adjusting for age and BMI. To the best of our knowledge, this is the first study investigating the relationship between circulating zonulin level (as a marker of intestinal permeability) and insulin resistance and leptin (as markers of metabolic disturbances associated with obesity) in childhood obesity. The results showed that zonulin was significantly higher in obese children when compared to healthy children, a finding indicating a potential role of zonulin in the etiopathogenesis of obesity and related disturbances.

It was aimed to evaluate KL-6 glycoprotein levels to determine if it may be a diagnostic marker for the connective tissue diseases (CTDs) predicting CTD-related interstitial lung diseases (ILDs) (CTD-ILD) development and to examine if there was a difference between patients and healthy controls. The study included 113 patients with CTD (45 CTD without lung involvement, 68 CTD-ILD) and 45 healthy control subjects. KL-6 glycoprotein levels were analyzed with ELISA in patients and the control group. The relationship between KL-6 glycoprotein levels and CTD-ILD was assessed. In the comparison of all the groups in the study, significantly higher levels of KL-6 were determined in the CTD-ILD group than in either the CTD without pulmonary involvement group or the healthy control group (p < 0.008 and p < 0.001, respectively). There was no statistically significant difference between the KL-6 levels in the healthy control group and the CTD without pulmonary involvement group (p = 0.289). The KL-6 levels did not differ significantly according to the connective tissue diseases in the diagnostic groups (systemic lupus erythematosus, Sjögren's syndrome, rheumatoid arthritis, mixed connective tissue disease, scleroderma, polymyositis/ dermatomyositis). In the healthy control group, there was a statistically significant difference between KL-6 levels in smokers and non-smokers. Smokers had significantly higher serum KL-6 levels compared with non-smokers (p < 0.05). There was no statistically significant difference between smoking status (pack-year) and serum KL-6 levels. There was no statistically significant correlation between serum KL-6 levels and time since diagnosis of CTD and CTD-ILD. The level of KL-6 as a predictive factor could be used to identify the clinical development of ILD before it is detected on imaging modality. Further prospective clinical studies are needed to define whether levels of KL-6 might have prognostic value or might predict progressive ILD.

Reducing the number of homeless, nonhuman animals entering and being euthanatized in community shelters is the principal motivation for most spay/neuter (S/N) programs in the United States. This study evaluated the impact of a subsidized S/N clinic opened in 2005 in Transylvania County, North Carolina, on the numbers of impoundments (and euthanasia) of dogs and cats and on the number of animal-related service and complaint calls at the community's only animal shelter. Before opening the local S/N clinic, a significant linear decline in the shelter's dog-intake rate per 1,000 human population was evident. This decline did not accelerate after the S/N clinic opened in 2005. The rate of decline in euthanasia did level off after the clinic opened, but the proportion of impounded dogs euthanatized did not change significantly. The median number of cats impounded and euthanatized yearly in the Transylvania County Animal Services shelter decreased significantly after the S/N clinic opened; the proportion of cats euthanatized did not change. The median annual number of service calls and complaints decreased or leveled off. Unfortunately, data regarding many factors essential for conclusively interpreting these results were not available.

The obesity-hypertension pathogenesis is complex. From the phenotype to molecular mechanism, there is a long way to clarify the mechanism. To explore the association between obesity and hypertension, we correlate the phenotypes such as the waist circumference (WC), body mass index (BMI), systolic blood pressure (SB), and diastolic blood pressure (DB) with the clinical laboratory data between four specific Chinese adult physical examination groups (newly diagnosed untreated just-obesity group, newly diagnosed untreated obesity-hypertension group, newly diagnosed untreated just-hypertension group, and normal healthy group), and the results may show something. To explore the mechanisms from obesity to hypertension by analyzing the correlations and differences between WC, BMI, SB, DB, and other clinical laboratory data indices in four specific Chinese adult physical examination groups. This cross-sectional study was conducted from September 2012 to July 2014, and 153 adult subjects, 34 women and 119 men, from 21 to 69 years, were taken from four characteristic Chinese adult physical examination groups (newly diagnosed untreated just-obesity group, newly diagnosed untreated obesity-hypertension group, newly diagnosed untreated just-hypertension group, and normal healthy group). The study was approved by the ethics committee of Hangzhou Center for Disease Control and Prevention. WC, BMI, SB, DB, and other clinical laboratory data were collected and analyzed by SPSS. Serum levels of albumin (ALB)，alanine aminotransferase (ALT), low density lipoprotein cholesterol (LDLC), triglyceride (TG), high density lipoprotein cholesterol (HDLC), alkaline phosphatase (ALP), uric acid (Ua), and TC/HDLC (odds ratio) were statistically significantly different between the four groups. WC statistically significantly positively correlated with BMI, ALT, Ua, and serum levels of glucose (GLU), and TC/HDLC, and negatively with ALB, HDLC, and serum levels of conjugated bilirubin (CB). BMI was statistically significantly positively related to ALT, Ua, LDLC, WC, and TC/HDLC, and negatively to ALB, HDLC, and CB. DB statistically significantly positively correlated with ALP, BMI, and WC. SB was statistically significantly positively related to LDLC, GLU, serum levels of fructosamine (FA), serum levels of the total protein (TC), BMI, and WC. The negative body effects of obesity are comprehensive. Obesity may lead to hypertension through multiple ways by different percents.

The consequences of stopping an assigned treatment in a withdrawn subject are unknown. It is difficult to make a single assumption about missing mechanisms for all clinical trials because there are complicated reactions in the human body to drugs due to the presence of complex biological networks, leading to data missing randomly or non-randomly. Currently there is no statistical method that can tell whether a difference between two treatments in the ITT population of a randomized clinical trial with missing data is significant at a pre-specified level. Making no assumptions about the missing mechanisms, we propose a generalized complete-case (GCC) analysis based on the data of completers. An evaluation of the impact of missing data on the ITT analysis reveals that a statistically significant GCC result implies a significant treatment effect in the ITT population at a pre-specified significance level unless, relative to the comparator, the test drug is poisonous to the non-completers as documented in their medical records. Applications of the GCC analysis are illustrated using literature data, and its properties and limits are discussed.

To evaluate the relationship between competition among fertility clinics and assisted reproductive technology (ART) treatment outcomes, particularly multiple births. Using clinic-level data from 1995 to 2001, we examined the relationship between competition and clinic-level ART outcomes and practice patterns. National database registry. Clinics performing ART. The number of clinics within a 20-mile (32.19-km) radius of a given clinic. Clinic-level births, singleton births, and multiple births per ART cycle; multiple births per ART birth; average number of embryos transferred per cycle; and the proportion of cycles for women under age 35 years. The number of competing clinics is not strongly associated with ART birth and multiple birth rates. Relative to clinics with no competitors, the rate of multiple births per cycle is lower (-0.03 percentage points) only for clinics with more than 15 competitors. Embryo transfer practices are not statistically significantly associated with the number of competitors. Clinic-level competition is strongly associated with patient mix. The proportion of cycles for patients under 35 years old is 6.4 percentage points lower for clinics with more than 15 competitors than for those with no competitors. Competition among fertility clinics does not appear to increase rates of multiple births from ART by promoting more aggressive embryo transfer decisions.

Plasma homovanillic acid (pHVA) levels were measured and the Brief Psychiatric Rating Scale (BPRS) scores were evaluated in 26 schizophrenic patients who had either never been medicated (neuroleptic-naive, first-episode subjects) or whose condition had become exacerbated following neuroleptic discontinuance (exacerbated subjects). All the subjects received medication with a fixed dose of a neuroleptic (haloperidol or fluphenazine, both 9 mg/day) for the first week and variable doses for the subsequent 4 weeks. In the neuroleptic-naive subjects, pHVA levels increased significantly 1 week after starting the protocol; this increase correlated significantly with clinical improvement of the BPRS positive symptom scores at week 5. In the neuroleptic-naive subjects, pHVA levels had declined to the baseline level by week 5. In the exacerbated subjects, there were no significant correlations between pHVA level changes at week 1 and later improvements of the BPRS positive symptom scores. These results suggest that the rise in pHVA levels occurring within 1 week after starting a fixed neuroleptic dose may predict a favorable clinical response in neuroleptic-naive schizophrenic patients.

Oral cavity carcinoma is the most common cancer in Indian population. Metastatic nodal disease is the most important prognostic factor for oral cancers. In head and neck cancers with clinically N0 neck, standard selective neck dissection is performed by protecting the spinal accessory nerve to remove level IIA & IIB lymph nodes. The purpose of this study was to analyze the significance of level IIB dissection in patients of oral cavity cancer who underwent primary surgery with functional neck dissection. Two hundred ten patients with clinically N0 neck underwent neck dissection, where level IIB lymph nodes were dissected, labelled and processed separately. Among 210 patients of clinically N0 neck, 168 patients were pathologically N0 (80 %). Out of remaining 42 (20 %), 36 (17.14 %) were pN1 and 6 (2.86 %) were pN2. Among those with pN1 (36), level IB was involved in 24 patients (66.67 %) and level IIA was involved in 12 patients (33.33 %). Only 2 patients had involvement of level IIB lymph nodes. Among 6 patients of pN2 disease, 4 patients had simultaneous involvement of level IB and level IIA lymph nodes. Remaining 2 patients had isolated involvement of level III lymph nodes. Thus only 2 patients (< 1 %) out of 210 clinically N0 oral squamous cell carcinoma showed level IIB lymph node involvement. Thus we conclude that a frozen section of level 2a is advisable to decide the need for level 2b node dissection in clinically N0 neck as the sensitivity of clinical evaluation is extremely low.

Fear of cancer recurrence (FCR) is a common concern among cancer survivors. Identifying survivors with clinically significant FCR requires validated screening measures and clinical cut-offs. We evaluated the Fear of Cancer Recurrence Inventory-Short Form (FCRI-SF) clinical cut-off in 2 samples. Level of FCR in study 1 participants (from an Australian randomized controlled trial: ConquerFear) was compared with FCRI-SF scores. Based on a biopsychosocial interview, clinicians rated participants as having nonclinical, subclinical, or clinical FCR. Study 2 participants (from a Canadian FCRI-English validation study) were classified as having clinical or nonclinical FCR by using the semistructured clinical interview for FCR (SIFCR). Receiver operating characteristic analyses evaluated the screening ability of the FCRI-SF against clinician ratings (study 1) and the SIFCR (study 2). In study 1, 167 cancer survivors (mean age: 53 years, SD = 10.1) participated. Clinicians rated 43% as having clinical FCR. In study 2, 40 cancer survivors (mean age: 68 years, SD = 7.0) participated; 25% met criteria for clinical FCR according to the SIFCR. For both studies 1 and 2, receiver operating characteristic analyses suggested a cut-off ≥22 on the FCRI-SF identified cancer survivors with clinical levels of FCR with adequate sensitivity and specificity. Establishing clinical cut-offs on FCR screening measures is crucial to tailoring individual care and conducting rigorous research. Our results suggest using a higher cut-off on the FCRI-SF than previously reported to identify clinically significant FCR. Continued evaluation and validation of the FCRI-SF cut-off is required across diverse cancer populations. Copyright © 2017 John Wiley & Sons, Ltd.

To compare sociodemographic and clinical characteristics in patients with burning mouth syndrome (BMS) and their relationship with pain. Cross-sectional clinical study. University-Hospital. 75 BMS patients were enrolled. The study was conducted between September 2011 and March 2012 at the "Federico II" University of Naples. Demographic characteristics and clinical information including age, sex, educational level, marital status, job status, age at disease onset, oral symptoms, and triggers were collected via questionnaire interviews. To assess pain intensity the visual analogue scale (VAS) was administered. Descriptive statistics were collected, and Pearson Chi-square tests, Kruskal-Wallis nonparametric tests and the Spearman bivariate correlation were performed. The mean age was 61.17 (±11.75, female/male ratio = 3:1). The mean age at disease onset was 56.75 (±12.01). A low educational level (8.57 ± 4.95) and 80% of unemployment were found. Job status and age at disease onset correlated with the VAS scale (P = 0.019 and P = 0.015, respectively). Tongue morphology changes, taste disturbances, and intraoral foreign body sensation have a significant dependence on gender (P = 0.049, 0.001, and 0.045, respectively); intraoral foreign body sensation has a significant dependence on marital status (P = 0.033); taste disturbances have a significant dependence on job status. (P = 0.049); xerostomia has a significant dependence on age (P = 0.039); and tongue color changes and a bitter taste have a significant dependence on educational level (P = 0.040 and 0.022, respectively). Marital status and educational level have a significant dependence on the triggers (P = 0.036 and 0.049, respectively). The prevalence of BMS is higher in women, and in married, unemployed, and less highly educated patients. Burning is the most frequent symptom while stressful life events are the most frequent trigger reported. Wiley Periodicals, Inc.

Familial dysautonomia (FD) is an autosomal recessive congenital neuropathy, primarily presented in Ashkenazi Jews. The most common mutation in FD patients results from a single base pair substitution of an intronic splice site in the IKBKAP gene which disrupts normal mRNA splicing and leads to tissue-specific reduction of IKBKAP protein (IKAP). To date, treatment of FD patients remains preventative, symptomatic and supportive. Based on previous in vitro evidence that tocotrienols, members of the vitamin E family, upregulate transcription of the IKBKAP gene, we aimed to investigate whether a similar effects was observed in vivo. In the current study, we assessed the effects of tocotrienol treatment on FD patients' symptoms and IKBKAP expression in white blood cells. The initial daily doses of 50 or 100 mg tocotrienol, doubled after 3 months, was administered to 32 FD patients. Twenty-eight FD patients completed the 6-month study. The first 3 months of tocotrienol treatment was associated with a significant increase in IKBKAP expression level in FD patients' blood. Despite doubling the dose after the initial 3 months of treatment, IKBKAP expression level returned to baseline by the end of the 6-month treatment. Clinical improvement was noted in the reported clinical questionnaire (with regard to dizziness, bloching, sweating, number of pneumonia, cough episodes, and walking stability), however, no significant effect was observed in any clinical measurements (weight, height, oxygen saturation, blood pressure, tear production, histamine test, vibration threshold test, nerve conduction, and heart rate variability) following Tocotrienol treatment. In conclusion, tocotrienol treatment appears significantly beneficial by clinical evaluation for some FD patients in a few clinical parameters; however it was not significant by clinical measurements. This open-label study shows the complexity of effect of tocotrienol treatment on FD patients' clinical outcomes and on IKBKAP expression level compared to in vitro results. A longitudinal study with an increased sample size is required in the future to better understand tocotrienol affect on FD patients.

To text the feasibility of a psychological intervention package administered to 49 pelvic exenteration candidates, aimed at evaluating the preoperative prevalence of psychological distress and assessing the presence of any correlation between preoperative psychological distress and clinical variables such as pain and hospitalization length. Patients were referred to the psychology unit from the very beginning of their clinical pathway and were administered the Psychological Distress Inventory (PDI) and the Mini-Mental Adjustment to Cancer (Mini-MAC) questionnaire at prehospital admission. Patients presenting with a significant level of distress received nonstandardized psychological support. Statistical analyses were performed to detect the presence of any correlation between psychological variables at prehospital admission and clinical outcomes. The 40% of patients had significant levels of distress at prehospital admission (PDI ≥ 30). As regards Mini-MAC, the mean value of fighting spirit attitude and fatalism was higher in our sample than in the normative sample of the Mini-MAC validation study in the Italian cancer population. Their anxious preoccupation attitude was lower. There were no correlations between clinical and psychological variables: level of postsurgery pain was higher (3.7) in the subgroup of patients with presurgery PDI < 30 compared with those with PDI ≥ 30 (3.5). However, this difference was not statistically significant (P = 1.00). Considering hospitalization length, the above described trend was similar. Although highly distressed, pelvic exenteration candidates show an adaptive range of coping mechanisms. This calls for a greater effort in studying the complexity of their psychoemotional status to provide them with the best multidisciplinary care. Extensive study of the real effectiveness of psychological intervention is warranted: randomized clinical trials could help in detecting the presence of any correlation between clinical and psychological variables in a multidisciplinary approach.

Natriuretic peptide type B (BNP) is a marker of myocardium injury. This peptide has been associated with metabolic risk markers, although controversy exists in this regard. The aim of the present study was to determine the correlation of plasma BNP levels with metabolic risk parameters. A retrospective, observational study that included 152 patients, who were classified according to their clinical diagnosis as patients with metabolic syndrome. Plasma BNP levels and clinical metabolic parameters were assessed by using Spearmańs rank correlation coefficient. A significant inverse association with weight (r=-.408; p<.0001) and BMI (r=-.443; p<.001) was obtained. While a positive significant association with systolic pressure (r=.324; p<.001) was observed. A significant decrease was found in BNP levels and components of metabolic syndrome. (p<.05). Based on the results from this study, we can conclude that BNP determination could be an adequate metabolic marker. Copyright © 2018 Elsevier España, S.L.U. All rights reserved.

Recently, there has been interest in non-mammalian collagen sources such as fish collagen in periodontal regeneration. In the present study, collagen barrier membrane of fish origin was assessed in the treatment of periodontal intrabony defects. Ten systemically healthy chronic periodontitis patients having a paired osseous defect in the mandibular posterior teeth were selected and randomly assigned to receive a collagen membrane (test) or open flap debridement (control) in a split mouth design. Clinical parameters such as Plaque index, Gingival bleeding index, Probing pocket depth, Relative attachment level, and Recession were recorded at baseline, 3, 6, and at 9 months, while radiographic evaluation was done to assess alveolar crestal bone level and percentage of defect fill at 6 and 9 months using autoCAD 2007 software. Student's t test (two-tailed, dependent) was used to find the significance of study parameters on continuous scale. Significance was set at 5% level of significance. Wilcoxon signed rank test was used to find the significance of percentage change of defect fill. The comparison between the two groups did not show any statistically significant differences in the parameters assessed (P > 0.05) but, within each group, clinical parameters showed statistically significant differences from baseline to 9 months (P < 0.05). Within the limits of the study, it can be inferred that no significant differences were found either by using collagen membrane of fish origin or open flap debridement in the treatment of periodontal intrabony defects.

Plasma cytokine profiling in sibling pairs discordant for autism spectrum disorder

PubMed Central

2013-01-01

Objective Converging lines of evidence point to the existence of immune dysfunction in autism spectrum disorder (ASD), which could directly affect several key neurodevelopmental processes. Previous studies have shown higher cytokine levels in patients with autism compared with matched controls or subjects with other developmental disorders. In the current study, we used plasma-cytokine profiling for 25 discordant sibling pairs to evaluate whether these alterations occur within families with ASD. Methods Plasma-cytokine profiling was conducted using an array-based multiplex sandwich ELISA for simultaneous quantitative measurement of 40 unique targets. We also analyzed the correlations between cytokine levels and clinically relevant quantitative traits (Vineland Adaptive Behavior Scale in Autism (VABS) composite score, Social Responsiveness Scale (SRS) total T score, head circumference, and full intelligence quotient (IQ)). In addition, because of the high phenotypic heterogeneity of ASD, we defined four subgroups of subjects (those who were non-verbal, those with gastrointestinal issues, those with regressive autism, and those with a history of allergies), which encompass common and/or recurrent endophenotypes in ASD, and tested the cytokine levels in each group. Results None of the measured parameters showed significant differences between children with ASD and their related typically developing siblings. However, specific target levels did correlate with quantitative clinical traits, and these were significantly different when the ASD subgroups were analyzed. It is notable that these differences seem to be attributable to a predisposing immunogenetic background, as no other significant differences were noticed between discordant sibling pairs. Interleukin-1β appears to be the cytokine most involved in quantitative traits and clinical subgroups of ASD. Conclusions In the present study, we found a lack of significant differences in plasma-cytokine levels between children with ASD and in their related non-autistic siblings. Thus, our results support the evidence that the immune profiles of children with autism do not differ from their typically developing siblings. However, the significant association of cytokine levels with the quantitative traits and the clinical subgroups analyzed suggests that altered immune responses may affect core feature of ASD.

This study examined the DSM-5 severity criterion for bulimia nervosa (BN) based on the frequency of inappropriate weight compensatory behaviors. 199 community volunteers classified with BN were categorized using DSM-5 severity levels and compared on demographic and clinical variables. 77 (39%) participants were categorized as mild, 68 (34%) as moderate, 32 (16%) as severe, and 22 (11%) as extreme. The severity groups did not differ significantly in demographic variables or body mass index. Shape and Weight concerns did not differ significantly across severity groups. Binge eating differed with the extreme group having higher frequency than the severe, moderate, and mild groups, which did not differ from each other. Restraint differed with the extreme group having significantly higher levels than the mild group. Eating concerns differed with the extreme group having higher levels than moderate and mild groups. Depression differed with the extreme group having higher levels than severe, moderate, and mild groups, which did not differ from each other. Findings from this non-clinical group provide new, albeit modest, support for DSM-5 severity rating for BN based on frequency of inappropriate weight compensatory behaviors. Statistical findings indicate that differences in collateral clinical variables associated with the DSM-5 severity ratings reflect small effect sizes. Further research is needed with treatment-seeking patient groups with BN to establish the validity of the DSM-5 severity specifier and should include broader clinical and functional validators.

Although multidisciplinary heart failure (HF) clinics are efficacious, it is not known how patient factors or HF clinic structural indicators and process measures have an impact on the cumulative health care costs. In this retrospective cohort study using administrative databases in Ontario, Canada, we identified 1216 HF patients discharged alive after an acute care hospitalization in 2006 and treated at a HF clinic. The primary outcome was the cumulative 1-year health care costs. A hierarchical generalized linear model with a logarithmic link and gamma distribution was developed to determine patient-level and clinic-level predictors of cost. The mean 1-year cost was $27,809 (range, $69 to $343,743). There was a 7-fold variation in the mean costs by clinic, from $14,670 to $96,524. Delays in being seen at a HF clinic were a significant patient-level predictor of costs (rate ratio 1.0015 per day; P<0.001). Being treated at a clinic with >3 physicians was associated with lower costs (rate ratio 0.78; P=0.035). Unmeasured patient-level differences accounted for 97.4% of the between-patient variations in cost. The between-clinic variation in costs decreased by 16.3% when patient-level factors were accounted for; it decreased by a further 49.8% when clinic-level factors were added. From a policy perspective, the wide spectrum of HF clinic structure translates to inefficient care. Greater guidance as to the type of patient seen at a HF clinic, the timeliness of the initial visit, and the most appropriate structure of the HF clinics may potentially result in more cost-effective care.

Canine leishmaniosis has a wide range of disease severity from mild (stage I), to severe (stages II–III), or very severe disease (stage IV). The objective of the study was to evaluate and compare serum antibody levels, Leishmania infantum specific IFN-γ production and TLR2 and TLR4 transcripts in non-stimulated blood from dogs with different clinical stages at the time of diagnosis as well as blood parasitemia. Enzyme-Linked ImmunoSorbent Assay (ELISAs) were performed to determine serum antibody levels and IFN-γ production and quantitative polymerase chain reaction (qPCRs) in order to determine blood parasite load and TLR2 and TLR4 transcripts. Older dogs were significantly affected by more severe disease with higher antibody levels and blood parasitemia than dogs with mild disease. IFN-γ production was significantly higher in dogs with stage I disease when compared to dogs with more severe disease. Relative quantification of TLR2 in dogs with mild disease was similar to that of control dogs. On the other hand, TLR2 transcripts were significantly higher in dogs with severe disease as compared with that from control healthy dogs. No differences were found in TLR4 relative quantification between groups. This study demonstrates that dogs with different clinical stages of leishmaniosis present different levels of biological markers indicative of different immune responses. PMID:29547503

Few studies have examined the relationship of individual periodontal parameters with individual systemic biomarkers. This study assessed the possible association between specific clinical parameters of periodontitis and systemic biomarkers of coronary heart disease risk in coronary heart disease patients with periodontitis. Angiographically proven coronary heart disease patients with periodontitis (n = 317), aged >30 years and without other systemic illness were examined. Periodontal clinical parameters of bleeding on probing (BOP), probing depth (PD), and clinical attachment level (CAL) and systemic levels of high-sensitivity C-reactive protein (CRP), fibrinogen (FIB) and white blood cells (WBC) were noted and analyzed to identify associations through linear and stepwise multiple regression analyses. Unadjusted linear regression showed significant associations between periodontal and systemic parameters; the strongest association (r = 0.629; p < 0.001) was found between BOP and CRP levels, the periodontal and systemic inflammation marker, respectively. Stepwise regression analysis models revealed that BOP was a predictor of systemic CRP levels (p < 0.0001). BOP was the only periodontal parameter significantly associated with each systemic parameter (CRP, FIB, and WBC). In coronary heart disease patients with periodontitis, BOP is strongly associated with systemic CRP levels; this association possibly reflects the potential significance of the local periodontal inflammatory burden for systemic inflammation. © 2014 John Wiley & Sons A/S.

This paper explored the present status of self-efficacy and job involvement of clinical nursing teachers and investigated the predictive power of teachers' personal background variables on such, as well as the relationship between self-efficacy and job involvement. A total of 419 participants in the survey sample were chosen among clinical nursing teachers at 19 public and private institutes of technology and junior colleges in Taiwan in 2004. The self-developed structural questionnaire was categorized into three sections, including personal background data, job self-efficacy related to the clinical teaching inventory and job involvement related to clinical teaching inventory. Of the total 419 questionnaires distributed for this cross-sectional survey, 266 valid copies were registered, at a recovery rate of 63%. Findings indicated that both the job self-efficacy and job involvement of clinical nursing teachers are at a medium to high level and that significant differences exist in job self-efficacy and job involvement based on differences in age, marital status, teaching seniority, teacher qualifications, and job satisfaction. Second, samples have significantly different performance in self-efficacy due to differences in education level attained and the medical institution to which nursing teachers had been assigned. Self-efficacy and job involvement are significantly positively correlated. These results can serve as a reference for the cultivation of nursing teachers and reform of clinical nursing education in the future.

Sepsis is associated with systemic inflammatory responses and induction of intravascular fibrin formation. Our aim is to investigate whether three fibrin-related markers (FRM) reflect the extent of coagulation activation in vivo and evaluate their clinical usefulness in identifying as well as monitoring patients with sepsis. Fibrin-degradation products (FDP), D-dimer and soluble fibrin monomer assays were measured on plasma samples from patients in the ICU with sepsis (n = 37), systemic inflammatory response syndrome (SIRS) (n = 35) and healthy individuals (n = 15). The levels were correlated with each other and also with fibrinogen, prothrombin time, platelets and antithrombin III. Clinical correlation was also performed for the diagnosis of sepsis and longitudinal monitoring for survival or death.There was strong correlation between the three FRM (r = 0.38-0.93, P < 0.0001) with only fibrin monomer correlating significantly with prothrombin time, fibrinogen and platelet levels. Clinically, all three FRM could discriminate between patients with sepsis, SIRS and healthy individuals with FDP, and D-dimer showing statistical significance (P < 0.05). No FRM predicted outcome from a single measurement but FDP was significantly able to predict patient survival from serial samples [mean FDP (μg/ml) from 35.36 to 21.37 (first to third ICU-day), P < 0.05]. Fibrin monomer appears the most sensitive indicator of coagulation activation, whereas D-dimer and FDP levels can significantly differentiate ICU patients with sepsis from those without. In addition, FDP would be preferable for monitoring with its statistically significant time-dependent prediction of survival or death from sepsis.

Nepal has a distinct topography that makes reproductive health and family planning services difficult to access, particularly in remote mountain and hill regions where over a quarter of modern contraceptive users rely exclusively on vasectomy. A three-level random intercept logistic regression analysis was applied on data from the 2011 Nepal Demographic and Health Survey to investigate the extent of influence of mobile family planning clinics on the odds of a male or a female sterilization, adjusting for relevant characteristics including ecological differences and random effects. The analyses included a sample of 2014 sterilization users, considering responses from currently married women of reproductive ages. The odds of a male sterilization were significantly higher in a mobile clinic than those in a government hospital (odds ratio, 1.65; 95% confidence interval, 1.21-2.25). The effects remained unaltered and statistically significant after adjusting for sociodemographic and clustering effects. Random effects were highly significant, which suggest the extent of heterogeneity in vasectomy use at the community and district levels. The odds of vasectomy use in mobile clinics were significantly higher among couples residing in hill and mountain regions and among those with three or more sons or those with only daughters. Mobile clinics significantly increase the uptake of vasectomy in hard-to-reach areas of Nepal. Reproductive health interventions should consider mobile clinics as an effective strategy to improve access to male-based modern methods and enhance gender equity in family planning. Family planning interventions in hard-to-reach communities could consider mobile clinic as an effective strategy to promote male-based modern methods. Improving access to vasectomy could substantially reduce unmet need for family planning in countries experiencing rapid fertility transition. Copyright © 2014 Elsevier Inc. All rights reserved.

The purpose of this study was to determine if a computer-aided instruction learning module improves students' knowledge of the neuroanatomy/physiology and clinical examination of the dorsal column-medial lemniscal (DCML) system. Sixty-one physical therapy students enrolled in a clinical neurology course in entry-level PT educational programs at two universities participated in the study. Students from University-1 (U1;) had not had a previous neuroanatomy course, while students from University-2 (U2;) had taken a neuroanatomy course in the previous semester. Before and after working with the learning module, students took a paper-and-pencil test on the neuroanatomy/physiology and clinical examination of the DCML system. Kruskal-Wallis one-way ANOVA and Mann-Whitney tests were used to determine if differences existed between neuroanatomy/physiology examination scores and clinical examination scores before and after taking the learning module, and between student groups based on university attended. For students from U1, neuroanatomy/physiology post-test scores improved significantly over pre-test scores (p < 0.001), while post-test scores of students from U2 did not (p = 0.60). Neuroanatomy/physiology pre-test scores from U2 were significantly better than those from U1 (p < 0.001); there was no significant difference in post-test scores (p = 0.062). Clinical examination pre-test and post-test scores from U2 were significantly better than those from U1 (p < 0.001). Clinical examination post-test scores improved significantly from the pre-test scores for both U1 (p < 0.001) and U2 (p < 0.001).

Increased pro-brain natriuretic peptide (pro-BNP) or troponin T-hypersensitivity (TnT-HSST) levels are common in liver cirrhosis. We conducted a retrospective observational study aimed to evaluate the correlation of pro-BNP and TnT-HSST levels with the clinical characteristics, laboratory data and in-hospital outcomes of patients with liver cirrhosis. We selected cirrhotic patients admitted to our hospital between January 2011 and June 2014. All eligible patients had pro-BNP or TnT-HSST data, or both. The pro-BNP and TnT-HSST data were further divided according to the presence of cardiac diseases. The prevalence of pro-BNP level >900pg/mL was 41.72% (63 of 151 patients). The prevalence of TnT-HSST level >0.05ng/mL was 11.22% (45 of 401 patients). In the overall analysis, pro-BNP level significantly correlated with red blood cell (RBC), platelet, ascites, blood urea nitrogen (BUN), creatinine (Cr), Child-Pugh score, model for end-stage liver disease (MELD) score and in-hospital death; TnT-HSST level significantly correlated with white blood cell, ascites, albumin (ALB), BUN, Cr, Child-Pugh score, MELD score and in-hospital death. In patients with cardiac diseases, pro-BNP level significantly correlated with RBC, ascites, BUN, Cr, Child-Pugh score and MELD score; TnT-HSST level significantly correlated with sex, ascites, white blood cell, ALB, BUN, Cr, Child-Pugh score, MELD score and in-hospital death. In patients without cardiac diseases, pro-BNP level significantly correlated with ascites, RBC, platelet, BUN, Cr, MELD score and in-hospital death; TnT-HSST level significantly correlated with age, ascites, RBC, ALB, BUN, Cr, Child-Pugh score, MELD score and in-hospital death. Pro-BNP and TnT-HSST levels significantly correlated with the severity of liver dysfunction and in-hospital mortality in cirrhosis. Copyright © 2017 Southern Society for Clinical Investigation.

The profiles of microRNAs change significantly in gastric cancer. MiR-146a is reported to be a tumor suppressor in pancreatic cancer, breast cancer, and prostate cancer. We investigated the clinical significance of miR-146a in gastric cancer, in particular focusing on hypothetical miR-146a target genes, such as epidermal growth factor receptor (EGFR) and interleukin-1 receptor-associated kinase (IRAK1). We examined miR-146a levels in 90 gastric cancer samples by q-real-time (qRT)-PCR and analyzed the association between miR-146a levels and clinicopathologic factors and prognosis. The regulation of EGFR and IRAK1 by miR-146a was examined with miR-146a-transfected gastric cancer cells. Moreover, we analyzed the association between miR-146a levels and the G/C single nucleotide polymorphism (SNP) within pre-miR-146a seed sequences in 76 gastric cancer samples, using direct sequencing of genomic DNA. In 90 clinical samples of gastric cancer, miR-146a levels in cancer tissues were significantly lower than those in the corresponding noncancerous tissue (P < 0.001). Lower levels of miR-146a were associated with lymph node metastasis and venous invasion (P < 0.05). Moreover, a lower level of miR-146a was an independent prognostic factor for overall survival (P = 0.003). Ectopic expression of miR-146a inhibited migration and invasion and downregulated EGFR and IRAK1 expression in gastric cancer cells. In addition, G/C SNP within the pre-miR-146a seed sequence significantly reduced miR-146a levels in the GG genotype compared with the CC genotype. MiR-146a contains an SNP, which is associated with mature miR-146a expression. MiR-146a targeting of EGFR and IRAK1 is an independent prognostic factor in gastric cancer cases.

Tissue injury causing immune response is an integral part of surgical procedure. Evaluation of the degree of surgical trauma could help to improve postoperative management and determine the clinical outcomes. We analyzed serum levels of alarmins, including S100A5, S100A6, S100A8, S100A9, S100A11, and S100A12; high-mobility group box 1; and heat-shock protein 70, after elective major abdominal surgery (n = 82). Blood samples were collected for three consecutive days after surgery. The goals were to evaluate the relationships among the serum levels of alarmins and selected surgical characteristics and to test potential of alarmins to predict the clinical outcomes. Significant, positive correlations were found for high-mobility group box 1 with the length of surgery, blood loss, and intraoperative fluid intake for all three days of blood sampling. The protein S100A8 serum levels showed positive correlations with intensive care unit length of stay, 28-day and in-hospital mortality. The protein S100A12 serum levels had significant, positive correlations with intensive care unit length of stay, 28-day mortality, and in-hospital mortality. We did not find significant differences in alarmin levels between cancer and noncancer subjects. The high-mobility group box 1 serum levels reflect the degree of surgical injury, whereas proteins S100A8 and S100A12 might be considered good predictors of major abdominal surgery morbidity and mortality.

Carboxyhemoglobin levels in blood reflect endogenous carbon monoxide production and are often measured during routine blood gas analysis. Endogenous carbon monoxide production has been reported to be increased during sepsis, but carboxyhemoglobin levels have not been thoroughly evaluated as a biomarker of sepsis. We sought to determine whether carboxyhemoglobin levels were elevated during sepsis in a high risk population of premature neonates. We conducted a retrospective cohort study of 30 infants in two neonatal intensive care units using electronic medical and laboratory records. The majority of infants were extremely premature and extremely low birth weight, and 25 had at least one episode of sepsis. We collected all carboxyhemoglobin measurements during their in-patient stay and examined the relationship between carboxyhemoglobin and a variety of clinical and laboratory parameters, in addition to the presence or absence of sepsis, using linear mixed-effect models. We found that postnatal age had the most significant effect on carboxyhemoglobin levels, and other significant associations were identified with gestational age, hemoglobin concentration, oxyhemoglobin saturation, and blood pH. Accounting for these covariates, there was no significant relationship between the onset of sepsis and carboxyhemoglobin levels. Our results show that carboxyhemoglobin is unlikely to be a clinically useful biomarker of sepsis in premature infants, and raise a note of caution about factors which may confound the use of carbon monoxide as a clinical biomarker for other disease processes such as hemolysis.

We have previously examined the clinical manifestations, treatments and prognosis of 177 patients with urea cycle disorders (UCDs) from January 1999 to March 2009 in Japan. In this study, we investigated the incidence of clinical manifestations in different peak blood ammonia level at onset in UCD patients, and examined the growth of OTCD (ornithine transcarbamylase deficiency) patients. The UCD patients who had a high peak blood ammonia level at onset showed significantly high incidence of convulsion and abnormal head computed tomography or magnetic resonance imaging. The patients also showed significantly high incidence of hemodialysis and liver transplantation. Choice of therapeutic agents for long-term treatment is not different between peak blood ammonia levels at the onset, except for the use of special amino-acid formulas. Growth retardation is not affected by high peak blood ammonia level at onset; however, 32% of male and 52% of female OTCD patients over 1 year old were plotted under the 10th percentile, and showed growth failure. The final height of the male and female OTCD patients were 166.2±5.5 and 150.3±7.2 cm, respectively. Although the prognosis of UCDs was improved significantly, it is considered that there are still many difficulties in the UCD patient's life.

The purpose of this study was to investigate the change of the plasma oxidative stress level in children with IgA nephropathy (IgAN) and analyze its relativity to the clinical and pathological classification. To discuss the early effects of angiotensin-converting enzyme inhibitors (ACEIs) on the plasma oxidative stress level in children with IgA nephropathy. Thirty-eight children with IgAN were divided into groups according to their clinical features, pathologic grades, and treatments. Twenty healthy children were included in the control group. The plasma level of advanced oxidation protein products (AOPPs), malonaldehyde (MDA), and superoxide dismutase (SOD) were detected. The plasma level of oxidative stress was significantly increased in the IgAN group, including a higher plasma level of AOPP and MDA and a lower plasma level of SOD. After treatment, the plasma level of oxidative stress was significantly decreased in the ACEI group. The children with IgAN had an increase in the plasma level of oxidative stress, expressed as an increased plasma level of AOPP and MDA and a decreased plasma level of SOD. Oxidative stress was associated with the progression of IgAN in children. Early treatment with ACEI therapy can significantly reduce the plasma level of oxidative stress in children with IgAN. © The Author(s) 2016.

Because of its neutrophil-activating properties, interleukin-8 (IL-8) may play an important role in the pathophysiology of sepsis. We measured circulating IL-8 levels in 47 patients with clinical sepsis. Levels on admission were elevated in 42 of the 47 patients (89%) and were comparable in patients with gram-positive or gram-negative infections. Patients with shock had significantly higher IL-8 levels than normotensive patients (P = 0.0014, Wilcoxon-Mann-Whitney test), whereas no differences in IL-8 levels were found between patients with or without adult respiratory distress syndrome. Patients who died had higher IL-8 levels on admission than the patients who survived. The largest differences in IL-8 levels between survivors and nonsurvivors was found when only patients with positive cultures were considered (P = 0.0342). IL-8 levels appeared to correlate significantly with lactate levels and inversely with leukocyte and platelet numbers and mean arterial pressure. In addition, the IL-8 level in the sepsis patients was found to correlate significantly with levels of IL-6, elastase-alpha 1-antitrypsin, and C3a. Serial observations revealed that in most patients IL-8 levels decreased, irrespective of the outcome. Thus, our results demonstrate that IL-8 levels are increased in most patients with sepsis and correlate with some important clinical, biochemical, and inflammatory parameters. These findings suggest a role for IL-8 in the pathophysiology of sepsis. PMID:1612748

Vitamin D deficiency and insufficiency and the metabolic syndrome are two common health issues worldwide. The association between these two health problems is subject to debate. This study aims to investigate the association between vitamin D deficiency or insufficiency and the metabolic syndrome in a sample of osteoporotic postmenopausal women attending a family practice clinic in Amman-Jordan. This was an observational cross sectional study. It was carried out in the family practice clinic in Jordan University Hospital. The study included all postmenopausal osteoporotic women attending the clinic between June 2011 and May 2012, yielding a total of 326 subjects. The association between metabolic syndrome and serum vitamin D levels was investigated. Waist circumference, body mass index, triglycerides and fasting blood sugar were significantly higher among postmenopausal women with metabolic syndrome, but HDL cholesterol was significantly lower (p<0.05). The prevalence of metabolic syndrome among all study participants was 42.9%. Triglycerides and LDL cholesterol were significantly higher among women deficiency or insufficiency (p<0.05). The prevalence of vitamin D deficiency or insufficiency was 45.7%. Among patients with metabolic syndrome, the prevalence of vitamin D deficiency or insufficiency was 50.7%. Findings of the current study suggest a lack of relationship between serum vitamin D and metabolic syndrome. However, a significant inverse relationship was found between serum vitamin D levels and both serum triglycerides and LDL levels.

To evaluate the level of participation of clinical nurses from Castellón where Universitat JaumeI nursing students do their clinical clerkship. To identify the variables that may influence clinical nurses' participation in students' clinical mentorship. This observational, cross-sectional and descriptive study was conducted by applying the validated Involvement, Motivation, Satisfaction, Obstacles and Commitment (IMSOC) questionnaire. The variables collected were: age, work environment and previous training. The study was conducted between January and December 2014. The sample included 117 nurses. The overall mean questionnaire score was 122.838 (standard deviation: ±18.692; interquartile range 95%: 119.415-126.26). The variable "previous training for mentorship students" was statistically significant in the overall score and for all dimensions (P<.05). Primary care nurses obtained better scores in the dimension Implication than professionals working at other care levels. The level of participation of the clinical nurses from Castellón is adequate. The previous training that professionals receive for mentoring students improves both their level of participation and primary care level. Extending this research to other national and international environments is recommended. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

Summary Aims The aim of this clinical trial was to compare clinical and biochemical healing outcomes following ultrasonic mechanical instrumentation versus ultrasonic mechanical instrumentation associated with topical subgingival application of amino acids and sodium hyaluronate gel. Methods Eleven systemically healthy subjects with moderate-severe chronic periodontitis, who had four sites with pocket probing depth and clinical attachment level greater than or equal to 5 mm were randomly assigned to two different types of treatment: two pockets were treated with ultrasonic debridement (Control Group) and two pockets with ultrasonic mechanical instrumentation associated with 0,5 ml of amino acids and sodium hyaluronate gel (Test Group). Probing depth, clinical attachment level, plaque index and bleeding on probing were recorded at baseline, 45 and 90 days. Levels of calprotectin and myeloperoxidase activity in gingival crevicular fluid were assessed at baseline and on day 7 and 45. Results Statistical significance was found between baseline and day 45 in relation to probing depth reduction and bleeding on probing between groups for both of the tested treatments. Significant reductions in μg/sample of calprotectin and myeloperoxidase were found after 1-week and an increase at 45 days in both groups. There were no statistically significant differences between other variables evaluated in this study. Conclusions These data suggest that subgingival application of hyaluronic acid following ultrasonic mechanical instrumentation is beneficial for improving periodontal parameters. PMID:23087790

This study aimed to compare the levels of tumour necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β) and interleukin-6 (IL-6) between apical periodontitis lesions with different clinical and histological features. Based on clinical data and history of disease, 100 human apical periodontitis lesions were categorised as either asymptomatic or symptomatic lesions. According to histological examination, lesions were divided into periapical granulomas and radicular cysts. Pulp tissues of 25 impacted wisdom teeth were used as controls. Homogenised tissue samples were centrifuged and supernatants were used for the determination of cytokine levels by enzyme-linked immunosorbent assay. Significantly higher levels of IL-1β and IL-6 were found in symptomatic lesions compared with asymptomatic lesions and control tissues (P < 0.001, P < 0.001, respectively). The concentration of IL-1β was significantly higher in radicular cysts compared with periapical granulomas (P = 0.003). Symptomatic lesions, as judged by high local production of IL-1β and IL-6, represent an immunologically active stage of the disease. © 2014 Australian Society of Endodontology.

Psychiatrists in clinical practice face a number of stressors related to patient care, such as overwork. On the other hand, they gain satisfaction from their work. We quantified and assessed the potential relationship between levels of occupational stress, satisfaction, and depressive symptoms among Japanese clinical psychiatrists. We surveyed 206 psychiatrists with up to 15 years of clinical experience who primarily worked in patient care. Levels of occupational stress and occupational satisfaction were measured using the Visual Analogue Scale and the level of depressive symptoms was measured by the Center for Epidemiologic Studies Depression Scale. Workplace stressors and satisfiers were also evaluated. Out of 206 psychiatrists, 154 (74.8%) responded to the survey. The respondents' mean (SD) age was 34.3 (5.2) years. The estimated prevalence of significant depressive symptoms was 34.4% (n = 53), and the experienced frequent violence was 14.9% (n = 23). The level of depressive symptoms was inversely correlated with the level of occupational satisfaction. In respondents who reported a moderate level of occupational stress, having fewer depressive symptoms was associated with higher occupational satisfaction, but this association was not significant in those who reported a high level of stress. In addition, high occupational satisfaction was associated with interest towards work content, ability to work at one's discretion, opportunities for growth and career development, and ease of communication with supervisors and colleagues. Nearly one-third of the psychiatrists screened positive for significant depressive symptoms. Having fewer depressive symptoms was associated with higher occupational satisfaction in those who reported a moderate level of stress. Implications from the present findings may be to enhance occupational satisfaction by discussing work interests with a supervisor, as well as increased opportunities for career development, which may prevent depression among psychiatrists.

Soluble immune receptors (SIRs) have been proposed as biomarkers in patients with atopic dermatitis (AD). However, their clinical applicability in affected children has rarely been studied. To assess the diagnostic usefulness of serum SIRs in childhood AD by correlating the obtained receptor profiles with serological parameters and clinical features such as age, AD phenotype and disease severity. We investigated 100 children with AD. The sCD14, sCD23, sCD25, sCD30, total IgE (tIgE) and eosinophilic cationic protein (ECP) were determined using sera of all children. The clinical phenotype was classified as extrinsic AD (ADe) or intrinsic AD (ADi) by the presence of allergen-specific IgE antibodies. A total of 55 male and 45 female children were recruited. The sCD23, sCD25 and sCD30 serum levels revealed significant age-dependency. At a mean SCORAD of 40 (range 8-98), none of the evaluated SIRs was correlated to disease severity. In all, 73% of patients suffered from ADe while 27% showed the ADi phenotype. None of the analysed SIRs differed significantly between ADe and ADi patients, while tIgE and ECP levels were elevated in the ADe subgroup. The current study provides evidence that sCD23, sCD25 and sCD30 serum levels are highly age-dependent. Serum concentrations of all investigated SIRs did not significantly correlate with disease severity in children with AD and were not differentially expressed in patients of different AD phenotypes. Therefore, we believe that the studied SIRs cannot be regarded as clinically useful biomarkers for the assessment of childhood AD.

The aim of this study is to report on the treatment of mandibular Class II furcation defects with enamel matrix protein derivative (EMD) combined with a βTCP/HA (β-tricalcium phosphate/hydroxyapatite) alloplastic material. Thirteen patients were selected. All patients were nonsmokers, systemically healthy, and diagnosed with chronic periodontitis; had not taken medications known to interfere with periodontal tissue health and healing; presented one Class II mandibular furcation defect with horizontal probing equal to or greater than 4 mm at buccal site. The clinical parameters evaluated were probing depth (PD), relative gingival margin position (RGMP), relative vertical clinical attachment level (RVCAL), and relative horizontal clinical attachment level (RHCAL). A paired Student t test was used to detect differences between the baseline and 6-month measurements, with the level of significance of .05. After 6 months, the treatment produced a statistically significant reduction in PD and a significant gain in RVCAL and RHCAL, but no observable change in RGMP. RVCAL ranged from 13.77 (± 1.31) at baseline to 12.15 (± 1.29) after 6 months, with a mean change of -1.62 ± 1.00 mm (P < .05). RHCAL ranged from 5.54 (± 0.75) to 2.92 (± 0.92), with a mean change of -2.62 ± 0.63 mm (P < .05). After 6 months, 76.92% of the patients improved their diagnosis to Class I furcation defects while 23.08% remained as Class II. The present study has shown that positive clinical results may be expected from the combined treatment of Class II furcation defects with EMD and βTCP/HA, especially considering the gain of horizontal attachment level. Despite this result, controlled clinical studies are needed to confirm our outcomes.

Early and sensitive detection of islet graft damage is essential for improving posttransplant outcomes. MicroRNA 375 (miR375) has been reported as a biomarker of pancreatic β-cell death in small animal models. The miR375 levels were measured in purified human islets, sera from patients with autologous and allogeneic islet transplantation as well as total pancreatectomy alone (nontransplanted group). The miR375 levels were also determined in a miniaturized in vitro tube model comprising human islets and autologous blood. The miR375 expression level in islets was dose-dependent (P < 0.001) and significantly elevated after islet damage in plasma in the in vitro model (P = 0.003). Clinical analysis revealed that circulating miR375 levels in both autologous and allogeneic islet recipients were significantly elevated for 7 days after islet infusion, compared with the nontransplanted group (P = 0.005 and <0.001, respectively). Furthermore, miR375 detected the difference in islet graft damage among 3 different anti-inflammatory protocols for clinical autologous transplantation (P < 0.01). Circulating miR375 can be a reliable biomarker to detect graft damage in clinical islet transplantation because serum C-peptide and proinsulin levels are difficult to interpret due to the influence of multiple factors, such as β-cell stress and physiological response.

We retrospectively evaluated the prognostic impact of the level of nodal involvement in patients with advanced oral squamous cell carcinoma (SCC). Between 2005 and 2010, 105 patients with clinical stage III or IV oral SCC had chemoradiotherapy preoperatively. Clinical (cN) and pathological nodal (pN) involvement was primarily at levels Ib and II. We defined nodal involvement at levels Ia and III-V as anterior and inferior extensions, respectively, and recorded such findings as extensive. With respect to pretreatment variables (age, clinical stage, clinical findings of the primary tumour, and nodal findings), univariate analysis showed that extensive cN was the only significant factor for overall survival (hazard ratio [HR], 3.27; 95% CI 1.50 to 7.13; p=0.001). Univariate analysis showed that all pN findings, including the nodal classification (invaded nodes, multiple, and contralateral) and extensive involvement were significant, and multivariate analysis confirmed that extensive pN (HR 4.71; 95% CI 1.85 to 11.97; p=0.001) and multiple pN (HR 2.59; 95% CI 1.10 to 6.09; p=0.029) were independent predictors of overall survival. Assessment based on the level of invaded neck nodes may be a better predictor of survival than the current nodal classification.

Methemoglobinemia is a relatively rare, but potentially life-threating medical condition, which may be induced by application of topical anaesthetic agents commonly used during endoscopic procedure. The aim of our study was to assess the influence of lidocaine used prior to transesophageal echocardiography (TEE) on the blood level of methemoglobin in vivo. Additionally we attempted to establish the occurrence rate of clinically evident lidocaine-induced methemoglobinemia on the basis of data collected in our institution. We retrospectively analyzed patient records from 3,354 TEEs performed in our echocardiographic laboratory over the course of 13 years in search for clinically evident methemoglobinemia cases. Additionally, 18 consecutive patients referred for TEE were included in the prospective part of our analysis. Blood samples were tested before and 60 min after pre-TEE lidocaine anesthesia application. Information concerning concomitant conditions and pharmacotherapy were also obtained. In 3,354 patients who underwent TEE in our institution no cases of clinically evident methemoglobinemia occurred. In the prospective part of the study, none of 18 patients [16 (89 %) men, mean age 63 ± 13] was diagnosed with either clinical symptoms of methemoglobinemia or exceeded normal blood concentration of methemoglobin. Initial mean methemoglobin level was 0.5 ± 0.1 % with mild, statistically (but not clinically) significant rise to 0.6 ± 0.1 % after 60 min (p = 0.02). Among the analyzed factors only the relation between the proton pump inhibitors intake and methemoglobin blood level rise was identified as statistically relevant (p = 0.03). In adults, pre-TEE lidocaine anesthesia with recommended dosage results in significant increase in methemoglobin blood level, which however does not exceed normal values and does not result in clinically evident methemoglobinemia.

Objectives We retrospectively investigated the clinical and endocrinological characteristics of adrenal incidentalomas. Methods We studied 61 patients who had been diagnosed with adrenal incidentalomas and had undergone detailed clinical and endocrinological evaluations while hospitalized. We used common criteria to diagnose the functional tumors, but for sub-clinical Cushing's syndrome, we used an updated set of diagnosis criteria: serum cortisol ≥1.8 μg/dL after a positive response to a 1-mg dexamethasone suppression test if the patient has a low morning ACTH level (<10 pg/mL) and a loss of the diurnal serum cortisol rhythm. Results Of the 61 patients, none (0%) had malignant tumors, 8 (13.1%) had pheochromocytoma, and 15 (24.6%) had primary aldosteronism; when diagnosed by our revised criteria, 13 (21.3%) had cortisol-secreting adenomas (Cushing's syndrome and sub-clinical Cushing's syndrome), and 25 (41.0%) had non-functional tumors. Compared with the non-functional tumor group, the primary aldosteronism group and the cortisol-secreting adenoma group were significantly younger and had significantly lower rates of hypokalemia, whereas the pheochromocytoma group had significantly larger tumors and a significantly lower body mass index. Conclusion Our study found a larger percentage of functional tumors among adrenal incidentalomas than past reports, partly because we used a lower serum cortisol level after a dexamethasone suppression test to diagnose sub-clinical Cushing's syndrome and because all of the patients were hospitalized and could therefore receive more detailed examinations. Young patients with hypokalemia or lean patients with large adrenal tumors warrant particularly careful investigation.

Introduction A “virtual patient” is defined as a computer program which simulates real patients' cases. The aim of this study was to determine whether the inclusion of virtual patients affects the level of factual knowledge of family medicine students at the undergraduate level. Methods This was a case-controlled prospective study. The students were randomly divided into experimental (EG: N = 51) and control (CG: N = 48) groups. The students in the EG were asked to practice diagnosis using virtual patients instead of the paper-based clinical cases which were solved by the students in the CG. The main observed variable in the study was knowledge of family medicine, determined by 50 multiple choice questions (MCQs) about knowledge of family medicine. Results There were no statistically significant differences in the groups' initial knowledge. At the final assessment of knowledge, there were no statistically significant differences between the groups, but there was a statistically significant difference between their initial and final knowledge. Conclusions The study showed that adding virtual patient cases to the curriculum, instead of paper clinical cases, did not affect the level of factual knowledge about family medicine. Virtual patients can be used, but a significant educational outcome is not expected. PMID:29568779

To measure the activity of matrix metalloproteinases (MMP)-2 and -9 in synovial fluid from the stifle joints of dogs with cranial cruciate ligament (CrCL) rupture and to compare that to values from contralateral stifle joints and dogs with clinically normal stifle joints. Additionally, the C-reactive protein (CRP) levels were also measured. Fourteen large breed dogs with unilateral CrCL rupture and 11 large breed normal dogs were included in this prospective clinical study. Synovial fluid was collected from CrCL-ruptured stifle joints, contralateral clinically normal stifle joints of the same dogs, and stifle joints of normal dogs. Serum was also collected. Synovial fluid activities of MMP-2 and MMP-9 and serum CRP level were measured. The MMP-2 activity in synovial fluid was significantly higher in CrCL-ruptured joints compared to contralateral joints and to stifles from normal dogs. There was no significant difference in activity of MMP-2 in contralateral joints of CrCL-ruptured dogs compared to normal dogs. Both serum CRP level and MMP-9 activity did not differ significantly between the studied conditions. It was confirmed that MMP-2 activity is significantly related to CrCL rupture, but there was a failure to demonstrate any significant increase in the contralateral joints compared to the stifle joints of normal dogs. The MMP-2 involvement in progressing CrCL disease still has to be defined.

The tryptophan metabolic pathway mediated by indolamine 2,3-dioxygenase (IDO), a tryptophan-degrading enzyme, plays an important role in controlling the development of allergic inflammation. The fractional concentration of exhaled nitric oxide (FeNO) is closely associated with the allergic state and is extensively used for the clinical evaluation of airway allergic inflammation. Clinical trials have rarely assessed the expression of IDO in childhood allergic asthma and its correlation with FeNO. To evaluate the IDO level in children with childhood allergic asthma and the relation between IDO levels and FeNO. Thirty children older than 5 years who were diagnosed the first time with allergic asthma were selected from the pediatric outpatient department. Another 30 healthy children were selected as controls. The subjects were evaluated by complete medical history, pulmonary function test results, skin prick test reaction, FeNO concentration test result, eosinophil count, and a disease severity score. Peripheral venous blood and induced sputum were obtained to measure the concentrations of IDO metabolites (ie, tryptophan and kynurenine). The IDO levels in the peripheral blood and induced sputum were significantly lower in patients with childhood allergic asthma than in children in the control group. The IDO level was negatively correlated with FeNO but was not significantly correlated with age, sex, blood eosinophil count, or disease severity scale. The expression of IDO was significantly lower in childhood allergic asthma, particularly in children with high FeNO levels. There was no significant relation between IDO levels and asthma severity.

2015-05-01

The aim of the study is to assess the administered activity levels versus visual-based image quality using visual grading regression (VGR) including an assessment of the newly stated image criteria for whole-body bone scintigraphy. A total of 90 patients was included and grouped in three levels of administered activity: 400, 500 and 600 MBq. Six clinical image criteria regarding image quality was formulated by experienced nuclear medicine physicians. Visual grading was performed in all images, where three physicians rated the fulfilment of the image criteria on a four-step ordinal scale. The results were analysed using VGR. A count analysis was also made where the total number of counts in both views was registered. The administered activity of 600 MBq gives significantly better image quality than 400 MBq in five of six criteria (P<0·05). Comparing the administered activity of 600 MBq to 500 MBq, four criteria of six show significantly better image quality (P<0·05). The administered activity of 500 MBq gives no significantly better image quality than 400 Mbq (P<0·05). The count analysis shows that none of the three levels of administrated activity fulfil the recommendations by the EANM. There was a significant improvement in perceived image quality using an activity level of 600 MBq compared to lower activity levels in whole-body bone scintigraphy for the gamma camera equipment end set-up used in this study. This type of visual-based grading study seems to be a valuable tool and easy to implement in the clinical environment. © 2014 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

Abstract This study was performed to investigate the relationship between the abundance of pathogenic gut microbes in Chinese patients with inflammatory bowel disease (IBD) and disease severity. We collected clinical data and fecal samples from 47 therapy-naive Chinese patients with ulcerative colitis (UC), 67 patients with Crohn disease (CD), and 48 healthy volunteers. Bacteria levels of Fusobacterium species (spp), enterotoxigenic Bacteroides fragilis (B fragilis), enteropathogenic Escherichia coli (E coli), and Enterococcus faecalis (E faecalis) were assessed by quantitative real-time PCR (qRT-PCR). Spearman correlation coefficients were calculated to test associations between bacterial content and clinical parameters. Compared to healthy controls, the levels of both Fusobacterium spp and E faecalis were significantly increased in the feces of patients with IBD (P < 0.01). B fragilis levels were higher (P < 0.05) and E faecalis levels lower (P < 0.05) in patients with CD compared to those with UC. Increased E faecalis colonization in CD associated positively with disease activity (P = 0.015), Crohn disease activity index (CDAI; R = 0.3118, P = 0.0108), and fecal calprotectin (P = 0.016). E faecalis and Fusobacterium spp are significantly enriched in patients with IBD, and increased E faecalis infection is associated with clinically active CD. PMID:27684872

To determine the D-dimer levels in pregnant women at term and the differences between pregnant women with different D-dimer levels. The plasma D-dimer concentrations in pregnant women at term were identified in a cross-sectional study. The clinical indicators that are potentially relevant to D-dimer levels were compared between the pregnant women with different D-dimer levels (i.e., normal, mildly increased, and severely increased). There were always some D-dimer concentration outliers in the pregnant women at term regardless of the presence or absence of complications, and there were no significant differences in maternal age, gestational age, gravidity, parity, blood count, blood coagulation, or liver function between the pregnant women with different D-dimer levels. D-dimer levels may vary significantly during pregnancy for unknown reasons. This variation, particularly in pregnant women at term, might lead to questionable diagnostic information regarding coagulation. Copyright © 2016 The Canadian Society of Clinical Chemists.

Objectives: To determine the associations between serum cancer antigen 15-3 levels and prognostic factors in patients with endometrial carcinomas. Additionally, we investigated the clinical utility of serum cancer antigen 15-3 levels in the selection of low-risk patients with endometrioid type, tumor size <2 cm, myometrial invasion ≤50%, and histological grade 1-2. Methods: Ninety-six patients, who were surgically staged at Ankara Yildirim Beyazit University, Ankara, Turkey, between 2007 and 2016, were retrospectively analyzed. Demographic, clinical, and surgical characteristics were retrieved from the patients’ hospital records. A p<0.05 was considered significant. Results: Fifteen patients had advanced (≥Stage II) disease, 14 patients had Type 2 histology, 20 patients had Grade 3 tumors, 23 patients had lymphovascular space invasion, and 10 patients had positive lymph node involvement. Serum cancer antigen 15-3 levels were significantly higher in patients with advanced (≥Stage II) disease, Type 2 histology, Grade 3 tumors, lymp°hovascular space invasion, and positive lymph node involvement (p<0.05). Serum cancer antigen 15-3 levels were also significantly correlated with tumor size (p=0.006). Serum cancer antigen 15-3 levels were significantly lower (95% confidence interval: 0.57−0.79; p=0.03) in low-risk patients compared to other endometrial carcinoma patients. A cutoff of 25.0 IU/mL was used to identify high-risk patients with a specificity of 100%. Conclusion: Serum cancer antigen 15-3 levels significantly correlated with prognostic factors and were a useful diagnostic tool for endometrial carcinomas. PMID:29114696

A randomized, controlled, clinical trial was conducted to examine the impact of a semistructured, 10-week, once weekly, 90-min/session bereavement support group intervention on immunological, neuroendocrine, and clinical health status in human immunodeficiency virus type 1-seropositive (HIV-1+) and HIV-1-seronegative (HIV-1−) homosexual men, compared to a standard of care control condition. A total of 119 homosexual men (74 HIV-1+ and 45 HIV-1−) were assessed at baseline, 10 weeks, and 6 months follow-up. At the 6-month follow-up assessment, the intervention groups exhibited significant beneficial effects compared to controls on changes in CD4 cell, total T-lymphocyte, and total lymphocyte counts, when baseline levels, antiretroviral medication use, CDC stage of disease, and other potentially confounding factors were accounted for. There was no statistically significant effect on the CD4/CD8 ratio or on the CD8 cell count. The effect on CD4 cell count was associated with group attendance and with changes in plasma cortisol level. Plasma cortisol levels decreased significantly among intervention subjects, compared to controls. A significantly reduced number of health care visits over the 6-month follow-up period among the intervention subjects supported the clinical relevance of the immunological changes observed for both HIV-1+ and HIV-1− individuals. These results indicate that behavioral interventions may have salutary immunological and clinical health effects following bereavement among HIV-1-infected individuals. The effect in HIV-1− individuals suggests that this bereavement support group intervention might have similar salutary effects in the general population. Potential effects of such interventions on clinical HIV disease progression are of interest and should be studied. PMID:9605995

Molecular basis of the potential of vitamin D to prevent cancer.

PubMed

Ingraham, Betty A; Bragdon, Beth; Nohe, Anja

2008-01-01

To review current research findings in cell biology, epidemiology, preclinical, and clinical trials on the protective effects of vitamin D against the development of cancers of the breast, colon, prostate, lung, and ovary. Current recommendations for optimal vitamin D status, the movement towards revision of standards, and reflections on healthy exposure to sunlight are also reviewed. Search methodology: A literature search was conducted in April and updated in September 2007. The Medline and Web of Knowledge databases were searched for primary and review articles published between 1970 and 2007, using the search terms 'vitamin D', 'calcitriol', 'cancer', 'chemoprevention', 'nuclear receptor', 'vitamin D receptor', 'apoptosis', 'cell cycle', 'epidemiology', and 'cell adhesion molecule'. Articles that focused on epidemiological, preclinical, and clinical evidence for vitamin D's effects were selected and additional articles were obtained from reference lists of the retrieved articles. An increasing body of research supports the hypothesis that the active form of vitamin D has significant, protective effects against the development of cancer. Epidemiological studies show an inverse association between sun exposure, serum levels of 25(OH)D, and intakes of vitamin D and risk of developing and/or surviving cancer. The protective effects of vitamin D result from its role as a nuclear transcription factor that regulates cell growth, differentiation, apoptosis and a wide range of cellular mechanisms central to the development of cancer. A significant number of individuals have serum vitamin D levels lower than what appears to protect against cancer, and the research community is currently revising the guidelines for optimal health. This will lead to improved public health policies and to reduced risk of cancer. Research strongly supports the view that efforts to improve vitamin D status would have significant protective effects against the development of cancer. The clinical research community is currently revising recommendations for optimal serum levels and for sensible levels of sun exposure, to levels greater than previously thought. Currently, most experts in the field believe that intakes of between 1000 and 4000 IU will lead to a more healthy level of serum 25(OH)D, at approximately 75 nmol/L that will offer significant protection effects against cancers of the breast, colon, prostate, ovary, lungs, and pancreas. The first randomized trial has shown significant protection against breast cancer, and other clinical trials will follow and ultimately lead to improved public health policies and significantly fewer cancers.

Many studies have investigated cerebrospinal fluid (CSF) monoamine metabolite levels in depressive disorders. However, their clinical significance is still unclear. We tried to determine whether CSF monoamine metabolite levels could be a state-dependent marker for major depressive disorder (MDD) based on analyses stratified by clinical variables in a relatively large sample. Subjects were 75 patients with MDD according to DSM-IV criteria and 87 healthy controls, matched for age, sex, and ethnicity (Japanese). They were recruited between May 2010 and November 2013. We measured homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA), and 3-methoxy-4-hydroxyphenylethyleneglycol (MHPG) in CSF samples by high-performance liquid chromatography. We analyzed the relationships of the metabolite levels with age, sex, diagnosis, psychotropic medication use, and depression severity. There was a weak positive correlation between age and 5-HIAA levels in controls (ρ = 0.26, P < .016) and a similar trend in patients, while sex was unrelated to any metabolite. All monoamine metabolites in moderately to severely depressed patients (17-item Hamilton Depression Rating Scale score > 12) were significantly lower than those in controls (P < .0005 for all 3 metabolites). We found that antidepressants decreased the levels of 5-HIAA (ρ = -0.39, P < .001) and MHPG (ρ = -0.49, P < .0001) and that antipsychotics increased levels of HVA (ρ = 0.24, P < .05). There was a strong correlation between HVA and 5-HIAA levels (controls: ρ = 0.79, P = .000001; MDD: ρ = 0.66, P = .000001). HVA levels (ρ = -0.43, P < .001) and 5-HIAA levels (ρ = -0.23, P < .05), but not MHPG levels (ρ = -0.18, P > .1), were related to depression severity. CSF 5-HIAA and HVA levels could be state-dependent markers in MDD patients. Since 5-HIAA levels greatly decrease with the use of antidepressants, HVA levels might be more useful in the clinical setting. © Copyright 2017 Physicians Postgraduate Press, Inc.

We aimed to detect the role of obesity on the healing response to periodontal therapy in terms of serum lipids, C-reactive protein (CRP) and both serum and gingival crevicular fluid adipocytokines. Thirty patients with periodontitis with (CPO) (n = 15) and without (n = 15) obesity and 15 healthy controls were included. Serum high-density lipoprotein, low-density lipoprotein, triglyceride, CRP levels and levels of adiponectin, interleukin (IL)-6, tumor necrosis factor (TNF)-α and IL-10 were evaluated before and 3 mo after initial periodontal therapy. Clinical periodontal measurements were also recorded at baseline and 3 mo. Periodontal parameters improved significantly in both periodontitis groups with or without obesity (p < 0.05) with no significant difference in terms of gain clinical attachment level (p > 0.05) and change in numbers of sites with probing depth ≥ 4 mm. High-density lipoprotein significantly increased in both groups (p > 0.05). CRP decreased significantly solely in the normal weight group. IL-6, IL-10 and TNF-α levels in gingival crevicular fluid improved significantly based on therapy in both groups (p < 0.05). Only TNF-α decreased significantly in the CPO, while adiponectin and IL-10 in addition to TNF-α improved significantly in the group of patients with periodontitis without obesity. Patients with CPO respond to periodontal therapy as well as the non-obese controls. This similar response is accompanied with consistent adipokine levels in gingival crevicular fluid. However, obesity affects the CRP and serum adipocytokine levels in response to therapy. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Simulation and guided reflective journaling have been identified as effective teaching and learning methods to develop critical thinking (CT) and clinical reasoning skills in nursing students. A descriptive correlational design was used to determine the relationship between CT and level of reflection using the Holistic Critical Thinking Skills Rubric (HCTSR) and the level of reflection on action assessment (LORAA), respectively, to evaluate 23 baccalaureate student-guided reflective journal entries after a simulation exercise with guided debriefing and after two subsequent clinical experiences. A statistically significant positive relationship (p < .01) was found between mean HCTSR and LORAA scores on all three journal entries, but no relationship to CT during simulation or on standardized test scores. The results also indicated support for use of the guided reflection after significant learning experiences. The LORAA and the HCTSR are effective measures of level of reflection and CT to evaluate learning from simulation and clinical experiences. [J Nurs Educ. 2016;55(11):645-650.].

Biomarkers for Alzheimer’s disease (AD) are vital for disease detection in the clinical setting. Discovered in our laboratory, activity-dependent neuroprotective protein (ADNP) is essential for brain formation and linked to cognitive functions. Here, we revealed that blood borne expression of ADNP and its paralog ADNP2 is correlated with premorbid intelligence, AD pathology, and clinical stage. Age adjustment showed significant associations between: 1] higher premorbid intelligence and greater serum ADNP, and 2] greater cortical amyloid and lower ADNP and ADNP2 mRNAs. Significant increases in ADNP mRNA levels were observed in patients ranging from mild cognitive impairment (MCI) to AD dementia. ADNP2 transcripts showed high correlation with ADNP transcripts, especially in AD dementia lymphocytes. ADNP plasma/serum and lymphocyte mRNA levels discriminated well between cognitively normal elderly, MCI, and AD dementia participants. Measuring ADNP blood-borne levels could bring us a step closer to effectively screening and tracking AD. PMID:26639975

Early clinical presentation of ST-segment-elevation myocardial infarction (STEMI) and non-ST-segment-elevation myocardial infarction affects patient management. Although local inflammatory activities are involved in the onset of MI, little is known about their impact on early clinical presentation. This study aimed to investigate whether local inflammatory activities affect early clinical presentation. This study comprised 94 and 17 patients with MI (STEMI, 69; non-STEMI, 25) and stable angina pectoris, respectively. We simultaneously investigated the culprit lesion morphologies using optical coherence tomography and inflammatory activities assessed by shedding matrix metalloproteinase 9 (MMP-9) and myeloperoxidase into the coronary circulation before and after stenting. Prevalence of plaque rupture, thin-cap fibroatheroma, and lipid arc or macrophage count was higher in patients with STEMI and non-STEMI than in those with stable angina pectoris. Red thrombus was frequently observed in STEMI compared with others. Local MMP-9 levels were significantly higher than systemic levels (systemic, 42.0 [27.9-73.2] ng/mL versus prestent local, 69.1 [32.2-152.3] ng/mL versus poststent local, 68.0 [35.6-133.3] ng/mL; P<0.01). Poststent local MMP-9 level was significantly elevated in patients with STEMI (STEMI, 109.9 [54.5-197.8] ng/mL versus non-STEMI: 52.9 [33.0-79.5] ng/mL; stable angina pectoris, 28.3 [14.2-40.0] ng/mL; P<0.01), whereas no difference was observed in the myeloperoxidase level. Poststent local MMP-9 and the presence of red thrombus are the independent determinants for STEMI in multivariate analysis. Local MMP-9 level could determine the early clinical presentation in patients with MI. Local inflammatory activity for atherosclerosis needs increased attention. © 2016 American Heart Association, Inc.

The aim of this cross-sectional study was to assess the correlation between dental plaque scores determined by the measurement of red autofluorescence or by visualization with a two-tone solution. Clinical photographs were used for this study. Overnight plaque from the anterior teeth of 48 participants was assessed for red fluorescence on photographs (taken with a QLF-camera) using a modified Quigley & Hein (mQH) index. A two-tone disclosing solution was applied. Total disclosed plaque was clinically assessed using the mQH index. In addition, total and blue disclosed plaque was scored on clinical photographs using the mQH index. A strong correlation was observed between the total disclosed plaque scored on photographs and the clinical scores (r = 0.70 at site level; r = 0.88 at subject level). The correlation between red fluorescent plaque and total plaque, as assessed on the photographs, was moderate to strong and significant (r = 0.50 at the site level; r = 0.70 at the subject level), with the total plaque scores consistently higher than the red fluorescent plaque scores. The correlation between red fluorescent plaque and blue disclosed plaque was weak to moderate and significant (r = 0.30 at the site level; r = 0.50 at the subject level). Plaque, as scored on white-light photographs, corresponds well with clinically assessed plaque. A weak to moderate correlation between red fluorescing plaque and total disclosed plaque or blue disclosed plaque was found. What at present is considered to be matured dental plaque, which appears blue following the application of a two-tone disclosing solution, is not in agreement with red fluorescent dental plaque assessment.

It is controversial whether the surgical restoration of sagittal balance and spinopelvic angulation in a single level lumbar degenerative spondylolisthesis results in clinical improvements. The purpose of this study to systematically review the available literature to determine whether the surgical correction of malalignment in lumbar degenerative spondylolisthesis correlates with improvements in patient-reported clinical outcomes. Literature searches were performed via Ovid Medline, Embase, CENTRAL and Web of Science using search terms "lumbar," "degenerative/spondylolisthesis" and "surgery/surgical/surgeries/fusion". This resulted in 844 articles and after reviewing the abstracts and full-texts, 13 articles were included for summary and final analysis. There were two Level II articles, four Level III articles and five Level IV articles. Most commonly used patient-reported outcome measures (PROMs) were Oswestery disability index (ODI) and visual analogue scale (VAS). Four articles were included for the final statistical analysis. There was no statistically significant difference between the patient groups who achieved successful surgical correction of malalignment and those who did not for either ODI (mean difference -0.94, CI -8.89-7.00) or VAS (mean difference 1.57, CI -3.16-6.30). Two studies assessed the efficacy of manual reduction of lumbar degenerative spondylolisthesis and their clinical outcomes after the operation, and there was no statistically significant improvement. Overall, the restoration of focal lumbar lordosis and restoration of sagittal balance for single-level lumbar degenerative spondylolisthesis does not seem to yield clinical improvements but well-powered studies on this specific topic is lacking in the current literature. Future well-powered studies are needed for a more definitive conclusion. Copyright © 2017 Elsevier Ltd. All rights reserved.

This study aims to define functioning levels of patients with schizophrenia by using a method of interpretable clustering based on a specific functioning scale, the Functional Remission Of General Schizophrenia (FROGS) scale, and to test their validity regarding clinical and neuroimaging characterization. In this observational study, patients with schizophrenia have been classified using a hierarchical top-down method called clustering using unsupervised binary trees (CUBT). Socio-demographic, clinical, and neuroimaging SPECT perfusion data were compared between the different clusters to ensure their clinical relevance. A total of 242 patients were analyzed. A four-group functioning level structure has been identified: 54 are classified as "minimal", 81 as "low", 64 as "moderate", and 43 as "high". The clustering shows satisfactory statistical properties, including reproducibility and discriminancy. The 4 clusters consistently differentiate patients. "High" functioning level patients reported significantly the lowest scores on the PANSS and the CDSS, and the highest scores on the GAF, the MARS and S-QoL 18. Functioning levels were significantly associated with cerebral perfusion of two relevant areas: the left inferior parietal cortex and the anterior cingulate. Our study provides relevant functioning levels in schizophrenia, and may enhance the use of functioning scale. Copyright © 2017 Elsevier B.V. All rights reserved.

Periodontitis is a risk factor for coronary heart disease (CHD). Both diseases are an inflammatory diseases and have the same potential pathogenic mechanisms. Interleukin-1β as a pro-inflammatory main cytokine, can be found in this both diseases. Gingival crevicular fluid (GCF) derived from the serum of gingival sulcus, affected by inflammatory mechanism and the amount of this fluid will increase in that situation. Objective: To analyze the relationship of interleukin-1β levels in gingival crevicular fluid (GCF) of CHD and non-CHD patients with periodontal status. Methods: Oral clinical examination (plaque index, bleeding on probing, pocket depth and clinical attachment loss) for 35 subjects with CHD and 35 non CHD were checked, laboratory test to measure the levels of Interleukin-1β was checked with enzyme-linked immunosorbent assay (ELISA). Results: There was no significant differences between interleukin-1β levels in CHD and non-CHD patients (p>0.05); there was no significant difference between the level of Interleukin-1β with periodontal status in CHD and control (non CHD) patients (p>0.05). Conclusions: levels of Interleukin-1β in CHD patients do not have a relationships with plaque index, pocket depth and clinical attachment loss, but has a relationships with bleeding on probing.

Objective To describe factors associated with pressure ulcers in individuals with spina bifida (SB) enrolled in the National Spina Bifida Patient Registry (NSBPR). Design Unbalanced longitudinal multicenter cohort study. Setting Nineteen SB clinics. Participants Individuals with SB (N=3153) enrolled in 19 clinic sites that participate in the NSBPR. Interventions Not applicable. Main Outcome Measures Pressure ulcer status (yes/no) at the annual visit between 2009 and 2012. Results Of 3153 total participants, 19% (n=603) reported ulcers at their most recent annual clinic visit. Seven factors–level of lesion, wheelchair use, urinary incontinence, shunt presence, above the knee orthopedic surgery, recent surgery, and male sex–were significantly associated with the presence of pressure ulcers. Of these factors, level of lesion, urinary incontinence, recent surgery, and male sex were included in the final logistic regression model. The 3 adjusting variables–SB type, SB clinic, and age group–were significant in all analyses (all P<.001). Conclusions By adjusting for SB type, SB clinic, and age group, we found that 7 factors–level of lesion, wheelchair use, urinary incontinence, shunt presence, above the knee orthopedic surgery, recent surgery, and male sex–were associated with pressure ulcers. Identifying key factors associated with the onset of pressure ulcers can be incorporated into clinical practice in ways that prevent and enhance treatment of pressure ulcers in the population with SB.

Systemic lupus erythematosus (SLE) disease manifestations are highly variable among patients, and the prevalence of individual clinical features differs significantly by ancestry. Serum tumor necrosis factor α (TNFα) levels are elevated in some SLE patients and may play a role in disease pathogenesis. The aim of this study was to look for associations between serum TNFα levels, clinical manifestations of SLE, autoantibodies, and serum interferon-α (IFNα) levels in a large multiancestral SLE cohort. We studied serum TNFα levels in 653 SLE patients (214 African Americans, 298 European Americans, and 141 Hispanic Americans). TNFα was measured using an enzyme-linked immunosorbent assay, and IFNα was measured with a functional reporter cell assay. Stratified and multivariate analyses were used to detect associations in each ancestral background separately, with meta-analysis when appropriate. Serum TNFα levels were significantly higher in SLE patients than in non-autoimmune disease controls (P < 5.0 × 10(-3) for each ancestral background). High serum TNFα levels were positively correlated with high serum IFNα levels when tested in the same sample across all ancestral backgrounds (odds ratio range 1.76-1.86, P = 4.8 × 10(-3) by Fisher's combined probability test). While serum TNFα levels alone did not differ significantly among SLE patients of different ancestral backgrounds, the proportion of patients with concurrently high levels of TNFα and IFNα was highest in African Americans and lowest in European Americans (P = 5.0 × 10(-3) ). Serum TNFα levels were not associated with autoantibodies, clinical criteria for the diagnosis of SLE, or age at the time of sampling. Serum TNFα levels are high in many SLE patients, and we observed a positive correlation between serum TNFα and IFNα levels. These data support a role for TNFα in the pathogenesis of SLE across all ancestral backgrounds and suggest important cytokine subgroups within the disease.

Objective Low levels of serum circulating 25-hydroxyvitamin D have been correlated with many health conditions, including chronic pain. Recent clinical practice guidelines define vitamin D levels < 20 ng/mL as deficient and values of 21–29 ng/mL as insufficient. Vitamin D insufficiency, including the most severe levels of deficiency, is more prevalent in black Americans. Ethnic and race group differences have been reported in both clinical and experimental pain, with black Americans reporting increased pain. The purpose of this study was to examine whether variation in vitamin D levels contribute to race differences in knee osteoarthritic pain. Methods The sample consisted of 94 participants (75% female), including 45 blacks and 49 whites with symptomatic knee osteoarthritis. Average age was 55.8 years (range 45–71 years). Participants completed a questionnaire on knee osteoarthritic symptoms and underwent quantitative sensory testing, including measures of heat and mechanical pain sensitivity. Results Blacks had significantly lower levels of vitamin D compared to whites, demonstrated greater clinical pain, and showed greater sensitivity to mechanical and heat pain. Low levels of vitamin D predicted increased experimental pain sensitivity, but did not predict self-reported clinical pain. Group differences in vitamin D significantly predicted group differences in heat pain and pressure pain thresholds on the index knee and ipsilateral forearm. Conclusion These data demonstrate race differences in experimental pain are mediated by differences in vitamin D level. Vitamin D deficiency may be a risk factor for increased knee osteoarthritic pain in black Americans. PMID:23135697

To compare the role of topically applied serum therapy with preservative-free artificial tear (AT) drops in patients with moderate to severe dry eye in Hansen's disease along with change in tear protein profile. 144 consecutive patients were randomly divided into three groups. After a baseline examination of clinical parameters, each of the patients received designated modality of topical therapy six times a day for 6 weeks. Post-treatment documentation of clinical parameters was done at 6 weeks, and then at 12 weeks after discontinuation of topical therapy. Analysis of three tear proteins using gel electrophoresis (sodium dodecyl sulfate polyacrylamide gel electrophoresis) was done at baseline, at the first and second post-treatment visits. In the cord blood serum (CBS) group, except for McMonnies score and staining score, all other clinical parameters showed continued improvement in the first and second post-treatment analyses. In the autologous serum (ALS) group, all the clinical parameters except Schirmer's I showed significant improvement in the first post-treatment analysis .This was sustained at a significant level in the second analysis except for tear film break-up time (TBUT) and conjunctival impression cytology grading. In the AT group, all the parameters improved at a non-significant level except for TBUT in the first analysis. In the next analysis, apart from McMonnies score and TBUT, other clinical parameters did not improve. In the ALS and CBS groups, tear lysozyme, lactoferrin levels improved in both post-treatment measurements (statistically insignificant).Total tear protein continued to increase at statistically significant levels in the first and second post-treatment analyses in the CBS group and at a statistically insignificant level in the ALS group. In the AT group, the three tear proteins continued to decrease in both the analyses. In moderate to severe dry eye in Hansen's disease, serum therapy in comparison with AT drops, improves clinical parameters and causes betterment in tear protein profile. CTRI/2013/07/003802.

There has been an increased emphasis on improving the level of evidence used as the basis for clinical treatment decisions. Several journals now require a statement of the level of evidence as a basic gauge of the study's strength. To review the levels of evidence in published articles in the clinical sports medicine literature and to determine if there has been an improvement in the levels of evidence published over the past 15 years. Systematic review. All articles from the years 1995, 2000, 2005, and 2010 in The American Journal of Sports Medicine (AJSM), Arthroscopy, and sports medicine-related articles from The Journal of Bone and Joint Surgery-American (JBJS-A) were analyzed. Articles were categorized by type and ranked for level of evidence according to guidelines from the Centre for Evidence-Based Medicine. Excluded were animal, cadaveric, and basic science articles; editorials; surveys; special topics; letters to the editor; and correspondence. Statistical analysis was performed with chi-square. A total of 1580 articles over the 4 periods met the inclusion criteria. The percentage of level 1 and 2 studies increased from 6.8% to 12.6%, 22.9%, and 23.5%, respectively (P < .0001), while level 4 and 5 studies decreased from 78.9% to 72.4%, 63.9%, and 53.0% (P < .0001). JBJS-A had a significant increase in level 1 and 2 studies (4.1%, 5.1%, 28.2%, 27.8%; P < .0001), as did AJSM (9.4%, 17.1%, 36.1%, 30.1%; P < .0001). Arthroscopy showed no significant change over time. Diagnostic, therapeutic, and prognostic studies all showed significant increases in level 1 and 2 studies over time (P < .05). There has been a statistically significant increase in the percentage of level 1 and 2 studies published in the sports medicine literature over the past 15 years, particularly in JBJS-A and AJSM. The largest increase was seen in diagnostic studies, while therapeutic and prognostic studies demonstrated modest improvement. The emphasis on increasing levels of evidence to guide treatment decisions for sports medicine patients may be taking effect. © 2014 The Author(s).

To explore the clinical characteristics and the diagnostic method of maple syrup urine disease (MSUD). From January 2003 to December 2011, a total of 14 000 patients with suspected inherited metabolism diseases were tested. The blood levels of leucine and valine of these patients were detected by tandem mass spectrometry. The urinary level of branched-chain α-ketoacids was tested by gas chromatography-mass spectrometry. And the diagnosis was based on the elevated levels of leucine and valine in blood and branched-chain α-ketoacids in urine. Thirty-three MSUD patients were confirmed. Their median age of initial visit was 0.17 years old (range: 7 days to 30 years old). The peak onset age of them was 2-30 days old, including 28 cases of neonatal onset (84.8%). The presenting symptoms of 28 cases were feeding difficulties (n=14), poor response, lethargy and seizures. Their median blood levels of leucine and valine (1901 (458-5804) and 600 (315-1617) µmol/L) were significantly higher than their normal levels ((50-300) and (60-250) µmol/L, both P<0.01). Their urinary levels of 2-OH-isovaleric acid, 2-keto-isovaleric acid, 2-keto-3-methylvaleric acid, 2-keto-isocaproic and acetylglycine (262.5 (5.4-624.3), 35.8 (1.9-156.0), 133.8 (7.4-611.5), 518.7 (17.2-2121.2) and 280.5 (11.0-1087.9) respectively) significantly higher than their normal levels (0, <0.1, 0, 0, <0.1 respectively, all P<0.01). In 5 intermittent MSUD patients, their blood levels of leucine and valine (402 (348-958) and 556 (322-808) µmol/L) were significantly higher than their normal levels (both P<0.01). The urinary level of 2-OH-isovaleric acid was significantly higher than its normal levels (P<0.01) while the urinary levels of other α-ketoacids were normal. The confirmation of MSUD remains difficult because of a lack of specific clinical features. The detections of tandem mass spectrometry and gas chromatography-mass spectrometry may aid its early diagnosis.

Weight loss is an effective treatment for children with non-alcoholic fatty liver disease (NAFLD) but it is very difficult to achieve outside of an intensive weight management program. We hypothesized that one can achieve success in improving NAFLD and weight-related outcomes in a structured and focused multidisciplinary clinical program feasible to implement in a gastroenterology clinic. Methods We prospectively tracked the clinical status of our patients enrolled in a multidisciplinary program of dietary and exercise advice through an Institutional Review Board-approved NAFLD registry. Each patient met with a gastroenterologist and dietician every 3 months for 30 minutes to set individualized goals and monitor progress. Results 108 children have been enrolled in the registry and of the 83 that were eligible for 1 year follow-up and included in the analysis, 39 patients returned, resulting in a 47% follow-up rate. These 39 patients showed statistically significant improvements in mean BMI z-score (−0.1 units, p<0.05), total (−11 mg/dL, p<0.05) and low density lipoprotein cholesterol (−9 mg/dL, p<0.05), and serum alanine aminotransferase (ALT) levels (−36 U/L) and aspartate amino transferase (AST) levels (−22 U/L) levels. Conclusion A clinically feasible multidisciplinary program of every 3 month 30 minute visits to set and monitor nutrition and exercise goals, stabilized mean BMI z-score and significantly improved aminotransferase levels at 1 year follow-up in obese pediatric patients with NAFLD.

Propolis is a natural resin made by bees from various plant sources and exerts antimicrobial, anti-inflammatory, immunomodulatory, antioxidant, and antidiabetic properties. The purpose of this study is to assess adjunctive benefit of propolis supplementation in individuals with chronic periodontitis (CP) and type 2 diabetes mellitus (DMt2) receiving scaling and root planing (SRP). A 6-month masked, randomized clinical trial comparing SRP with placebo (placebo + SRP group, n = 26) or SRP combined with a 6-month regimen of 400 mg oral propolis once daily (propolis + SRP group, n = 24) was performed in patients with long-standing DMt2 and CP. Treatment outcomes included changes in hemoglobin (Hb) A1c (primary outcome), fasting plasma glucose (FPG), serum N € -(carboxymethyl) lysine (CML), and periodontal parameters (secondary outcomes). After 3 and 6 months, average HbA1c levels in the propolis group decreased significantly by 0.82% and 0.96% units, respectively (P <0.01); however, there were no significant differences in the placebo group. Likewise, FPG and CML levels were significantly reduced in the propolis group, but not in the placebo group. After therapy, periodontal parameters of CP were significantly improved in both groups. The propolis group showed significantly greater probing depth reduction and clinical attachment level gain than the control group after 3 and 6 months. A 6-month regimen of 400 mg propolis once daily is a potentially viable adjunct to SRP that significantly reduces levels of HbA1c, FPG, and CML, and improves periodontal therapy outcome in people with DMt2 and CP.

Objective: We evaluated the short-term effect of a worksite-based walking incentive program to promote physical activity and well-being in employees of a private healthcare clinic. Design: A prospective, observational follow-up study. Setting: The study was conducted at Marshfield Clinic, a large private multispecialty group practice healthcare institution in Marshfield,Wisconsin, USA. Patients: Subjects for this study were Marshfield Clinic physicians and staff. Methods: From March 31, 2005 to August 20, 2005, physical activity level, body mass index (BMI) and other well-being characteristics were observed pre- and post-program among 191 female participants from the Marshfield Clinic. A brief Web site-accessible, self-reported survey assessed the effectiveness of the exercise program. Results: Our data show a statistically significant (p <0.0001) increase in participants’ physical activity level, while a significant (p = 0.021) decrease in mean BMI was observed. However, there was no evidence of our incentive program reducing participants’ blood pressure. Conclusion: Preliminary findings of our study suggest that the goal of worksite programs designed to support employees in their efforts to improve or maintain their level of wellness is potentially achievable. Continuing research is needed to further assess whether persistent health benefits can be induced by worksite wellness programs. PMID:17210975

The presence of neopterin in gingival crevicular fluid (GCF) is a marker for local and acute immune activation, and the presence of vascular cell adhesion molecule (VCAM-1) in GCF is accepted as a marker for chronic vascular inflammation. This study aimed to evaluate effects of periodontal treatment on GCF levels of neopterin and VCAM-1 in patients with chronic periodontitis (CP) with acute myocardial infarction (AMI) compared with systemically healthy CP patients. Sixty subjects (20 CP patients with AMI, 20 healthy CP patients, and 20 healthy controls) were included. GCF samples were analyzed at baseline and after 3 and 6 months, and the probing pocket depth (PD), clinical attachment level (CAL), bleeding on probing, gingival (GI) and plaque (PI) indices were recorded. We determined neopterin and VCAM-1 levels (concentration and total amount) using enzyme-linked immunosorbent assay (ELISA). No significant differences were seen between the AMI+CP and CP groups for PI, GI, GCF levels of neopterin and VCAM-1 at baseline. The number of teeth with 5 mm≤CAL<7 mm and CAL≥7 mm were significantly increased in the AMI+CP group at baseline. There were no significant differences between the AMI+CP and CP for PI, CAL, GCF volumes, and the AMI+CP group had the highest clinical improvement in the number of teeth with 5 mm≤CAL<7 mm at the sixth month. There were significant positive correlations between clinical periodontal inflammation and the presence of neopterin and VCAM-1 in GCF prior to and following periodontal treatment, and between the GCF volume and clinical parameters. Data suggest that the total amount and concentration of neopterin and VCAM-1 in GCF seemed to be closely associated with periodontal disease severity in CP patients with AMI. Moreover, the results of our study demonstrate that the past periodontal status is potentially correlated between groups, with similar periodontal disease severity.

To compare radiologic and clinical outcomes, including rates of dysphagia and dysphonia, using a no-profile stand-alone intervertebral spacer with integrated screw fixation versus an anterior cervical plate and spacer construct for single-level anterior cervical discectomy and fusion (ACDF) procedures. This multicenter, randomized, prospective study included 54 patients with degenerative disc disease requiring ACDF at a single level at C3-C7. Twenty-six patients underwent single-level ACDF with stand-alone spacers, and 28 with plate fixation and spacers. Analyses were based on comparison of perioperative outcomes, radiologic and clinical metrics, and incidence of dysphagia and/or dysphonia. Mean patient age was 48.8 ± 10.1years (53.7% female). No significant differences were observed between groups in operative time (101.8 ± 34.4 minutes, 114.4 ± 31.5 minutes), estimated blood loss (44.8 ± 76.5 mL, 82.5 ± 195.1 mL), or length of hospital stay (1.2 ± 0.6 days, 1.3 ± 0.6 days). Mean visual analog scale pain scores and Neck Disability Index scores improved significantly from preoperative to last follow-up (10.8 ± 2.6 months) in both groups (P < 0.05). Mean Voice Handicap Index and Eating Assessment Tool scores improved significantly from discharge to last follow-up in both groups (P < 0.05). From discharge to 6 months, the stand-alone spacers group consistently demonstrated greater improvement in Voice Handicap Index. Preoperative intervertebral disc and neuroforaminal heights increased significantly across treatment groups (P < 0.01), and no cases required surgical revision at index or adjacent levels. Anterior cervical discectomy and fusion with stand-alone spacers resulted in similar clinical and radiologic outcomes as compared with plate and spacers and may help minimize postoperative dysphonia.

A comparison of different treatment modalities of peri-implantitis can lead to the development and application of more effective and efficient methods of therapy in clinical practice. This study compares the effectiveness of open flap debridement used alone, with an approach employing the additional use of a diode laser for the treatment of peri-implantitis. Nineteen patients were divided into two groups and treated for peri-implantitis. In the control group (C group), the therapy utilized access flaps, plastic curettes, and sterilized gauzes soaked in saline. The test group (L group) was treated similarly but with additional irradiation using a diode laser. The parameters studied were pocket depth (PD) as the primary outcome variable, clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PI) as secondary variables. Measurements were performed at three different time points, baseline (BSL), 3 months, and 6 months after treatment. Three months after treatment, a mean PD reduction of 1.19 mm for the control group and 1.38 mm for the laser group was recorded. The corresponding BOP changes were 72.9 and 66.7%, respectively. These changes were significant and remained at the same levels at the 6-month examination (p < 0.05). CAL was reduced significantly only in group L from 5.25 mm at baseline to 4.54 mm at 3 months, remaining at this level at 6 months (p < 0.05). PI was reduced significantly in group C at 3 months from 37.5 to 6.3%. The 6-month data showed no statistically significant difference (p < 0.05) from the 3-month measurements. The two methods of therapy for peri-implantitis examined seemed to be equally efficient in the reduction of the PD and BOP 3 months after surgery, with the results sustained at the same levels after 6 months. CAL significantly improved only in the test group after 3 months. PI was reduced and maintained at low levels in both groups. Surgical treatment of peri-implantitis by access flaps leads to improvement of all clinical parameters studied while the additional use of diode laser does not seem to have an extra beneficiary effect. The additional use of a diode laser in the surgical treatment of peri-implantitis offers a limited clinical benefit.

Introduction Mozambique suffers from a critical shortage of healthcare workers. Mid-level healthcare workers, (Tecnicos de Medicina Geral (TMG)), in Mozambique require less money and time to train than physicians. From 2009–2010, the Mozambique Ministry of Health (MoH) and the International Training and Education Center for Health (I-TECH), University of Washington, Seattle, revised the TMG curriculum. To evaluate the effect of the curriculum revision, we used mixed methods to determine: 1) if TMGs meet the MoH's basic standards of clinical competency; and 2) do scores on measurements of clinical knowledge, physical exam, and clinical case scenarios differ by curriculum? Methods T-tests of differences in means examined differences in continuous score variables between curriculum groups. Univariate and multivariate linear regression models assess curriculum-related and demographic factors associated with assessment scores on each of the three evaluation methods at the p<0.05 level. Qualitative interviews and focus groups inform interpretation. Results We found no significant differences in sex, marital status and age between the 112 and 189 TMGs in initial and revised curriculum, respectively. Mean scores at graduation of initial curriculum TMGs were 56.7%, 63.5%, and 49.1% on the clinical cases, knowledge test, and physical exam, respectively. Scores did not differ significantly from TMGs in the revised curriculum. Results from linear regression models find that training institute was the most significant predictor of TMG scores on both the clinical cases and physical exam. Conclusion TMGs trained in either curriculum may be inadequately prepared to provide quality care. Curriculum changes are a necessary, but insufficient, part of improving TMG knowledge and skills overall. A more comprehensive, multi-level approach to improving TMG training that includes post-graduation mentoring, strengthening the pre-service internship training, and greater resources for training institute faculty may result in improvements in TMG capacity and patient care over time.

This study evaluated preclinical and clinical safety of marshmallow (Althaea officinalis L.) extract as a naturopathic medicine in common carp deliberately infected with Aeromonas hydrophila. The fish were fed 0 (control), 2.50, 5.00 and 10.00 g of marshmallow extract for 60 days in a preclinical experiment and then, challenged with A. hydrophila for a 10-day experiment. Significant increases were observed in aspartate aminotransferase (AST), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), creatine phosphokinase (CPK) activities and plasma creatinine levels in fish fed 10 g marshmallow extract per kg feed. However, alanine aminotransferase (ALT) significantly decreased on day 60. The fish fed 2.50 g marshmallow extract per kg feed indicated increased levels of total protein and globulin. There were no significant changes in albumin levels (p > 0.05). 2.50 and 5.00 g marshmallow significantly decreased triglyceride and cholesterol levels and increased glucose levels (p < 0.05). A. hydrophila significantly increased AST, ALT, LDH, ALP and CPK activities and plasma glucose, cholesterol, triglycerides and creatinine levels after 10 days (p < 0.05). Total plasma protein, albumin and globulin levels in fish challenged with A. hydrophila were significantly lower than the control group (p < 0.05). Marshmallow extract at 5.00 and 10.00 g can adjust plasma biochemical parameters in fish challenged with A. hydrophila. The results of preclinical studies and pharmaceutical toxicity of marshmallow extract revealed that dietary levels lower than 5.00 g were safe and effective. The results of this clinical study demonstrated that marshmallow extract (5.00 g kg-1 feed) can protect fish against A. hydrophila. PMID:28785391

The significance of mannose-binding lectin (MBL) and H-ficolin deficiency in febrile neutropenic (FN) patients and the correlation of these markers along with consecutive C-reactive protein (CRP) and procalcitonin (PCT) levels during the infectious process are investigated. Patients with any hematological malignancies who were defined to have "microbiologically confirmed infection", "clinically documented infection", or "fever of unknown origin" were included in this single-center prospective observational study. Serum levels of CRP, PCT, MBL, and H-ficolin were determined on 3 separate occasions: at baseline (between hospital admission and chemotherapy), at the onset of fever, and at the 72nd hour of fever. Forty-six patients (54% male, mean age 41.7 years) with 61 separate episodes of FN were evaluated. Eleven patients (23.9%) had "microbiologically confirmed infection", 17 (37%) had "clinically documented infection", and 18 (39.1%) had "fever of unknown origin". Fourteen (30.4%) patients had low (<500 ng/mL) initial MBL levels and 7 (15.21%) had low (<12,000 ng/mL) H-ficolin levels. Baseline MBL and H-ficolin levels did not significantly change on the first and third days of fever (p=0.076). Gram-negative bacteremia more frequently occurred in those with low initial MBL levels (p=0.006). PCT levels were significantly higher in those with microbiologically documented infections. Mean and median PCT levels were significantly higher in cases with bacteremia. There was no significant difference between hemoculture-positive and-negative patients in terms of CRP levels. Monitoring serum H-ficolin levels was shown to be of no benefit in terms of predicting severe infection. Low baseline MBL levels were correlated with high risk of gram-negative bacteremia; however, no significant correlation was shown in the follow-up. Close monitoring of PCT levels is warranted to provide more accurate and specific data while monitoring cases of bacteremia.

Multiple myeloma (MM) is a hematological cancer associated with increased clonal malignant plasma cells. Growth differentiation factor 15 (GDF 15) is a protein that is highly expressed in the bone marrow mesenchymal stem cells of patients with MM. This study investigated whether the clinical stage of the disease, treatment response and survival are affected by pretreatment serum GDF 15 levels. Serum GDF 15 levels were measured in 35 newly diagnosed MM patients and 27 healthy controls. The correlation between serum GDF 15 levels and various clinical and laboratory parameters was analyzed. The study demonstrated significantly higher levels of GDF 15 in MM patients. There was a negative correlation between GDF 15 levels, hemoglobin and albumin levels, and a positive correlation between GDF 15 levels, CRP, creatinine, β-2-microglobulin and stage. GDF 15 levels were lower in patients who could receive autologous stem cell transplantation compared to other groups, representing a statistically significant difference. However, in the survival analyses, GDF 15 level did not have an impact on survival. High serum levels of GDF 15 may indicate a poor treatment response. Our study supports the prognostic value of GDF 15 in MM. © 2013 S. Karger AG, Basel.

Given that tobacco smoking habit is a risk factor for periodontal diseases, the aim of this study was to compare clinical periodontal aspects between smokers and non-smokers. The clinical status were assessed in 55 patients, 29 smokers and 26 non-smokers, aged 30 to 50 years, with mean age of 40. The clinical parameters used were: probing depth (PD), plaque index (PI), gingival index (GI), clinical attachment level (CAL), gingival recession (GR) and gingival bleeding index (GBI) for arches (upper and lower) and teeth (anterior and posterior). Tooth loss was also evaluated in both groups. Multiple regression analysis showed: tendency of greater probing depth and clinical attachment level means for smokers; greater amount of plaque in smokers in all regions; greater gingival index means for non-smokers with clinical significance (p<0.05) in all regions. Although, without statistical significance, the analysis showed greater gingival bleeding index means almost always for non-smokers; similar gingival recession means in both groups and tendency of upper tooth loss in smokers and lower tooth loss in non-smokers. The findings of this study showed that clinical periodontal parameters may be different in smokers when compared to non-smokers and that masking of some periodontal signs can be a result of nicotine's vasoconstrictor effect.

The main purpose of this study was to investigate how receiving personal counseling at a university counseling center helps students deal with their personal problems and facilitates academic functioning. To that end, this study used both clinical and academic outcome measures that are relevant to the practice of counseling provided at a counseling center and its unique function in an institution of higher education. In addition, this study used the clinical significance methodology (N. S. Jacobson & P. Truax, 1991) that takes into account clients' differences in making clinically reliable and significant change. Pre-intake and post-termination surveys, including the Outcome Questionnaire (M. J. Lambert, K. Lunnen, V. Umphress, N. Hansen, & G. Burlingame, 1994), were completed by 78 clients, and the responses were analyzed using clinical significance methodology. The results revealed that those who made clinically reliable and significant change (i.e., the recovered group) reported the highest level of improvement in academic commitment to their educational goals and problem resolution, compared with those who did not make clinically significant change. The implications of the findings on practice for counseling at university counseling centers and for administrators in higher education institutions are discussed. (c) 2010 APA, all rights reserved.

Free clinics provide free primary care to the under or uninsured and have been playing an important role in serving the socio-economically disadvantaged. Free clinic patients represent a group of people who experience significant barriers to receiving diabetes prevention and intervention. This study examined diabetes attitudes among free clinic patients and volunteers. English or Spanish speaking patients and volunteers (N = 384), aged 18 years or older completed a self-administered survey. Diabetic patients and volunteers shared similar levels of diabetes attitudes compared to non-diabetic patients. Among patients, ethnicity, education level, diabetes education, and family history affected diabetes attitudes. Among volunteers, diabetes education was an important factor associated with positive diabetes attitudes. Whether the volunteer is a healthcare professional or student was related only to one aspect of diabetes attitudes, seriousness of type 2 diabetes. The results, indicating free clinic diabetic patients and volunteers shared similar levels of diabetes attitudes, were positive for maintaining and developing diabetes education programs at a free clinic. Unfortunately, the average length of volunteering at this free clinic was short and student volunteers likely leave the clinic upon graduation. Future research should examine issues of volunteer retention in free clinics. Diabetes education for patients may need to be diversified according to ethnicity, family history of diabetes, and educational level. Finally, non-healthcare professional volunteers could potentially be involved in diabetes education at a free clinic.

The present study examined the prevalence and correlates of clinical syndromes in a large group (N = 438) of incarcerated violent offenders, looking at differences between inmates with one and those with more than one clinical syndromes. More than a half of the sample (57%) reported clinically relevant symptoms for at least one clinical syndrome (n = 252), and the majority of them (38%) reported more syndromes in comorbidity (n = 169). Increased severity of clinical conditions (none, one, more than one syndrome) corresponded with significantly greater levels of personality disorder traits, psychological symptoms, dissociation, and negative emotionality, with large effect sizes. After controlling for co-occurrence of personality disorder traits and other symptoms, the presence of more than one comorbid syndrome significantly predicted unique variance in dissociation (positively) and positive emotionality (negatively). The presence of one clinical syndrome significantly and positively predicted negative emotionality. Findings support the possibility that the complexity, and not just the presence, of psychopathology could identify different groups of inmates. PMID:27913716

Few studies have determined the benefits of pharmacist-run clinics within a tertiary institution, and specifically on their capability to improve clinical outcomes as well as reduce the cost of illness. This study was designed to investigate the effectiveness of a pharmacist-managed risk factor management clinic (RFMP) in an acute care setting through the comparison of clinical (improvement in glycosylated hemoglobin level) and cost outcomes with patients receiving usual care. This single-center, observational study included patients aged ≥21 years old and diagnosed with type 2 diabetes mellitus (DM) who received care within the cardiology department of a tertiary institution between January 1, 2014, and December 31, 2015. The intervention group comprised patients who attended the RFMP for 3 to 6 months, and the usual-care group comprised patients who received standard cardiologist care. Univariate analysis and multiple linear regression were conducted to analyze the clinical and cost outcomes. A total of 142 patients with DM (71 patients in the intervention group and 71 patients in the usual-care group) with similar baseline characteristics were included. After adjusting for differences in baseline systolic blood pressure and triglyceride levels, the mean reduction in glycosylated hemoglobin level at 6 months from baseline in the intervention group was significantly lower by 0.78% compared with the usual-care group. Patients in the usual-care group had a significantly higher risk of hospital admissions within the 12 months from baseline compared with the intervention group (odds ratio, 3.84 [95% CI, 1.17-12.57]; P = 0.026). Significantly lower mean annual direct medical costs were also observed in the intervention group (US $8667.03 [$17,416.20] vs US $56,665.02 [$127,250.10]; P = 0.001). The pharmacist-managed RFMP exhibited improved clinical outcomes and reduced health care costs compared with usual care within a tertiary institute. Copyright © 2017 The Authors.

Context: Double-row rotator cuff repair methods have improved biomechanical performance when compared with single-row repairs. Objective: To review clinical outcomes of single-row versus double-row rotator cuff repair with the hypothesis that double-row rotator cuff repair will result in better clinical and radiographic outcomes. Data Sources: Published literature from January 1980 to April 2010. Key terms included rotator cuff, prospective studies, outcomes, and suture techniques. Study Selection: The literature was systematically searched, and 5 level I and II studies were found comparing clinical outcomes of single-row and double-row rotator cuff repair. Coleman methodology scores were calculated for each article. Data Extraction: Meta-analysis was performed, with treatment effect between single row and double row for clinical outcomes and with odds ratios for radiographic results. The sample size necessary to detect a given difference in clinical outcome between the 2 methods was calculated. Results: Three level I studies had Coleman scores of 80, 74, and 81, and two level II studies had scores of 78 and 73. There were 156 patients with single-row repairs and 147 patients with double-row repairs, both with an average follow-up of 23 months (range, 12-40 months). Double-row repairs resulted in a greater treatment effect for each validated outcome measure in 4 studies, but the differences were not clinically or statistically significant (range, 0.4-2.2 points; 95% confidence interval, –0.19, 4.68 points). Double-row repairs had better radiographic results, but the differences were also not statistically significant (P = 0.13). Two studies had adequate power to detect a 10-point difference between repair methods using the Constant score, and 1 study had power to detect a 5-point difference using the UCLA (University of California, Los Angeles) score. Conclusions: Double-row rotator cuff repair does not show a statistically significant improvement in clinical outcome or radiographic healing with short-term follow-up. PMID:23016017

Long-term clinical training based on a model core curriculum was conducted to nurture highly competent pharmacists in the clinical field. Pharmacists' responsibilities are expanding, and a system has been developed to help pharmacists gain accreditation, identify specialties, and improve their training. However, this system requires research competency. Therefore clinical research should be considered a part of clinical training to encourage high competency among pharmacists. Because the model core curriculum does not include a section on clinical research. Osaka City University Hospital introduced a hands-on clinical research experience program and evaluated its usefulness. A significant improvement in the level of knowledge and awareness of clinical research was seen among students who underwent the clinical research experience program. In addition, the level of student satisfaction was higher. These findings suggest that a clinical research experience program may be useful to nurture a greater awareness of clinical research and knowledge acquisition among pharmacists.

For patients with AIDS receiving antiretroviral treatment (ART) in South Africa via public clinics, improvements in nutritional status and economic productivity are likely to depend on adherence to drug regimen and quality of diet reflected in protein and micronutrient intakes. This study randomized 643 patients receiving ART from public clinics in the Free State Province into a Control group, a treatment group receiving adherence support, and a treatment group receiving adherence support and a nutritious food supplement. The data on food insecurity levels and time spent on various activities were analyzed for assessing the impact of the intervention programs. The main results were, first, changes between survey rounds 1 and 3 were significant at the 5% level for outcomes such as food insecurity levels and CD4 cell counts. Moreover, there was a significant reduction in food insecurity levels of patients with BMI less than 25 who received the nutritious food supplement. Second, the estimated parameters from models for patients' food insecurity levels showed that household incomes were significantly associated with lower food insecurity levels. Third, patients' BMI was a significant predictor of time spent on sedentary, moderate and overall activity levels, and it was important to separately evaluate the effects of BMI for under-weight and over-weight patients. Overall, the results indicated the need for reducing food insecurity levels, and for designing different interventions for under-weight and over-weight patients with AIDS for enhancing their labor productivity.

Paranoia is common and distressing in the general population and can impact on health, emotional well-being and social functioning, such that effective interventions are needed. Brief online mindfulness-based interventions (MBIs) have been shown to reduce symptoms of anxiety and depression in non-clinical samples; however, at present, there is no research investigating whether they can reduce paranoia. The current study explored whether a brief online MBI increased levels of mindfulness and reduced levels of paranoia in a non-clinical population. The mediating effect of mindfulness on any changes in paranoia was also investigated. One hundred and ten participants were randomly allocated to either a 2-week online MBI including 10 min of daily guided mindfulness practice or to a waitlist control condition. Measures of mindfulness and paranoia were administered at baseline, post-intervention and 1-week follow-up. Participants in the MBI group displayed significantly greater reductions in paranoia compared to the waitlist control group. Mediation analysis demonstrated that change in mindfulness skills (specifically the observe, describe and non-react facets of the FFMQ) mediated the relationship between intervention type and change in levels of paranoia. This study provides evidence that a brief online MBI can significantly reduce levels of paranoia in a non-clinical population. Furthermore, increases in mindfulness skills from this brief online MBI can mediate reductions in non-clinical paranoia. The limitations of the study are discussed.

The purpose of this study was to evaluate the association of pharmacogenomic factors and clinical outcome in autistic children and adolescents who were treated with risperidone for long periods. Eighty-two autistic subjects diagnosed with DSM-IV and who were treated with risperidone for more than 1 year were recruited. Pharmacogenomics and clinical outcome (CGI-I, aggressive, overactivity and repetitive score) were evaluated. Almost all patients showed stable symptoms on aggressive behaviour (89.02%), overactivity (71.95%), repetitive (70.89%) behaviour and all clinical symptoms (81.71%). Only 4.48% of patients showed minimally worse CGI-I score. Patients in the non-stable symptom group had DRD2 Taq1A non-wild-type (TT and CT) frequencies higher than the clinically stable group (p = 0.04), whereas other gene polymorphisms showed no significant association. Haplotype ACCTCAT (rs6311, rs1045642, rs1128503, rs1800497, rs4436578, rs1799978, rs6280) showed a significant association with non-stable clinical outcome (χ 2  = 6.642, p = 0.010). Risperidone levels showed no association with any clinical outcome. On the other hand, risperidone dose, 9-OH risperidone levels and prolactin levels were significantly higher in the non-stable compared to the stable symptom group (p = 0.013, p = 0.044, p = 0.030). Increased appetite was the most common adverse drug reaction and associated with higher body-weight, whereas it was not significantly associated with genetic variations and non-genetic information. In conclusion, risperidone showed efficacy to control autism, especially aggressive symptoms in long-term treatment. However, Taq1A T - carrier of dopamine 2 receptor gene - is associated with non-stable response in risperidone-treated patients. This study supports pharmacogenomics testing for personalized therapy with risperidone in autistic children and adolescents. © 2017 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

OBJECTIVES This study investigates the effects of high glucose content on patients undergoing cold crystalloid versus cold blood cardioplegia in terms of early clinical results, functional myocardial recovery and ischaemia–reperfusion injury in patients undergoing repair of acyanotic cardiac lesions. METHODS Patients were randomly assigned to receive either crystalloid (n = 31) or blood cardioplegia (n = 31). Early clinical results were assessed. Changes in left ventricular fractional shortening, arterial blood lactate levels, central venous saturation, cardiac Troponin I release and blood glucose concentration were measured during the first 24 h after ischaemia. RESULTS There was no significant difference in clinical outcomes and postoperative complication rates between groups. The postoperative changes in left ventricular function, lactate levels, central venous saturation and Troponin I were not significantly different between groups. The use of crystalloid cardioplegia was associated with significant increases in serum glucose compared with blood cardioplegia. CONCLUSIONS A high glucose content blood cardioplegia does not show any advantage compared with crystalloid cardioplegia in terms of clinical outcomes, functional recovery and the degree of ischaemic injury in infants and children undergoing repair of acyanotic heart lesions. High glucose concentration of the cardioplegic solution might potentiate ischaemia–reperfusion injury and diminish the beneficial effects of blood cardioplegia. PMID:26831677

 This study was planned to investigate whether smoker chronic periodontitis patients exhibit different salivary concentrations of C-telopeptide pyridinoline cross-links of type I collagen (ICTP) and osteocalcin (OC) compared to the non-smoker counterparts. Whole saliva samples, full-mouth clinical periodontal recordings were obtained from 33 otherwise healthy chronic periodontitis patients and 36 systemically, periodontally healthy control subjects. Chronic periodontitis patients and healthy control subjects were divided into smoker and non-smoker groups according to their self reports. Salivary ICTP, OC levels were determined by Enzyme-linked Immunoassays. Healthy control groups exhibited significantly lower values in all clinical periodontal measurements (P < 0.001). Smoker periodontitis patients revealed similar clinical periodontal index values with non-smoker counterparts (P > 0.05). Chronic periodontitis patients exhibited significantly higher salivary OC levels than healthy controls (P < 0.05). Smoker periodontitis patients revealed lower salivary OC levels than non-smoker counterparts (P < 0.001). Log ICTP levels in non-smoker chronic periodontitis patients were higher than non-smoker controls (P < 0.05). Smoker healthy control group revealed higher log ICTP levels than non-smoker counterparts (P < 0.001). Within the limits of this study, it may be suggested that suppression of salivary osteocalcin level by smoking may at least partly explain the deleterious effects of smoking on periodontal status. © 2010 John Wiley & Sons A/S.

The purpose of this investigation was to examine the clinical and microbiologic effects of apically repositioned flap surgery. Eighteen patients with chronic periodontitis received initial preparation (IP) including scaling and root planing, followed at 3 months by apically repositioned flap surgery at sites with pocket depth > 4 mm. Subjects were monitored clinically and microbiologically at baseline, 3 months after IP, and at 3, 6, 9, and 12 months postsurgery. Clinical assessments of plaque accumulation, gingival redness, suppuration, bleeding on probing, pocket depth, and attachment level were made at six sites per tooth. Subgingival plaque samples were taken from the mesial aspect of each tooth, and the presence and levels of 40 subgingival taxa were determined using checkerboard DNA-DNA hybridization. Significant reductions were seen in mean pocket depth and percentage of sites exhibiting gingival redness and bleeding on probing in both sites that received IP only and in sites receiving IP followed by surgery. Mean attachment level increased significantly for both sets of sites, but the increase was greater at the surgically treated sites. The total DNA probe counts were significantly reduced at sites in both treatment groups. At surgically treated sites, 19 of 40 taxa were significantly reduced posttherapy. At sites receiving IP only, 16 species were significantly reduced over time. While there were some reductions in mean counts after IP in this site group, the major reductions occurred after the surgical phase in these patients, even though these particular sites did not receive surgical therapy. The reduction in pocket depth by surgical means and the associated decrease in reservoirs of periodontal pathogens may be important in achieving sustained periodontal stability. PMID:12186343

To assess the role of preoperative serum 25 hydroxyvitamin D as predictor of hypocalcemia after total thyroidectomy. Retrospective cohort study. University teaching hospital. All consecutively performed total and completion thyroidectomies from February 2007 to December 2013 were reviewed through a hospital database and patient charts. The relationship between postthyroidectomy laboratory hypocalcemia (serum calcium≤2 mmol/L), clinical hypocalcemia, and preoperative serum 25 hydroxyvitamin D level was evaluated. Two hundred thirteen patients were analyzed. The incidence of postoperative laboratory and clinical hypocalcemia was 19.7% and 17.8%, respectively. The incidence of laboratory and clinical hypocalcemia among severely deficient (<25 nmol/L), deficient (<50 nmol/L), insufficient (<75 nmol/L), and sufficient (≥75 nmol/L) serum 25 hydroxyvitamin D levels was 54% versus 33.9%, 10% versus 18%, 2.9% versus 11.6%, and 3.1% versus 0%, respectively. Multiple logistic regression analysis revealed preoperative severe vitamin D deficiency as a significant independent predictor of postoperative hypocalcemia (odds ratio [OR], 7.3; 95% confidence interval [CI], 2.3-22.9; P=.001). Parathyroid hormone level was also found to be an independent predictor of postoperative hypocalcemia (OR, 0.6; 95% CI, 0.5-0.8; P=.002). Postoperative clinical and laboratory hypocalcemia is significantly associated with low levels of serum 25 hydroxyvitamin D. Our findings identify severe vitamin D deficiency (<25 nmol/L) as an independent predictor of postoperative laboratory hypocalcemia. Early identification and management of patients at risk may reduce morbidity and costs. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

Possible association between Helicobacter pylori infection (HPI) and nonalcoholic fatty liver disease (NAFLD) has been proposed by several studies with inconsistent conclusions. Here, we studied the association between HPI and NAFLD at 3 levels: (i) genetic level; (ii) small molecular level; and (iii) clinical level. Relation data between diseases, genes, and small molecules were acquired from Pathway Studio ResNet Mammalian database. Clinical data were acquired from 2263 elderly South Chinese subjects, including 603 NAFLD patients and 1660 subjects without NAFLD. Results showed that HPI and NAFLD present significantly shared genetic bases (95 genes, p value = 2.5E-72), demonstrating multiple common genetic pathways (enrichment p value ≤ 4.38E-20 for the top 10 pathways). Genetic network analysis suggested that mutual regulation may exist between HPI and NAFLD through 21 out of 95 genes. Furthermore, 85 out of the 95 genes manifested strong interaction with 12 small molecules/drugs that demonstrate effectiveness in treating both diseases. Clinical results showed that HPI rate in the NAFLD group was significantly higher than that in the group without NAFLD (51.9% vs. 43.6%; p value = 4.9E-4). Multivariate logistic regression results supported the observations and suggested that HPI served as a risk factor for NAFLD in the experiment data studied (odds ratio: 1.387, p value = 0.018). Results from this study support the hypothesis that complex biological association may exist between HPI and NAFLD, which partially explains the significant clinical co-incidence in the elderly population of south China.

One challenge facing dental hygiene, as well as dental, education is to identify clinical teaching strategies promoting critical thinking and clinical reasoning. These skills are crucial elements in the practice of dental hygiene. A two-group design (intervention, n=28, and control, n=30) assessed first-year dental hygiene students using pre-and post-Health Science Reasoning Test (HSRT) scores to evaluate the effect of reflective blogging on critical thinking skills. A reflective blog rubric, based on Mezirow's levels of reflection, determined if reflective blogging increased the level of reflection for dental hygiene students. The results suggest within this nonprobability sample that reflective blogging did not produce a significant change in students' HSRT scores (p>0.05). However, analyses of reflective blog rubric scores demonstrated statistically significant improvements (p<0.05) in students' levels of reflection. Furthermore, data analysis revealed a correlation (p<0.05) between HSRT subscale scores and the element of reflection scores for the intervention group. This study addressed needs of the dental and dental hygiene education community by examining the use of blogs, an emerging technology, as a tool for reflecting on clinical experiences and, in turn, for promoting critical thinking.

Survivin and monoamine oxidase A (MAOA) levels are elevated in prostate cancer (PCa) compared to normal prostate glands. However, the relationship between survivin and MAOA in PCa is unclear. We examined MAOA expression in the prostate lobes of a conditional PTEN-deficient mouse model mirroring human PCa, with or without survivin knockout. We also silenced one gene at a time and examined the expression of the other. We further evaluated the combination of MAOA inhibitors and survivin suppressants on the growth, viability, migration and invasion of PCa cells. Survivin and MAOA levels are both increased in clinical PCa tissues and significantly associated with patients' survival. Survivin depletion delayed MAOA increase during PCa progression, and silencing MAOA decreased survivin expression. The combination of MAOA inhibitors and the survivin suppressants (YM155 and SC144) showed significant synergy on the inhibition of PCa cell growth, migration and invasion with concomitant decrease in survivin and MMP-9 levels. There is a positive feedback loop between survivin and MAOA expression in PCa. Considering that survivin suppressants and MAOA inhibitors are currently available in clinical trials and clinical use, their synergistic effects in PCa support a rapid translation of this combination to clinical practice.

In a previous paper we reported that serum, urine and fecal zinc levels fell markedly in women taking a combination oral contraceptive agent (+OCA) and in women with normal menstrual cycles (-OCA) when they consumed a low-zinc diet (less than 0.2 mg/day) for 35 days. We evaluated other biochemical and clinical data in order to determine if depletion of accessible body zinc and/or physiologic adjustment to conserve body zinc stores had occurred. Neither low zinc intake nor oral contraceptive use appeared to influence nitrogen balance or body weight. Use of contraceptive drugs appeared to influence the response of blood parameters to zinc depletion. Serum transferrin and cholesterol declined significantly in the -OCA group, whereas alkaline phosphatase and gamma-globulin changed significantly in both groups. Clinical problems developed in all the subjects with serum zinc levels below 50 microgram/dl during the study; three of the six with serum zinc levels above 50 microgram/dl also complained of clinical symptoms. The results suggest that zinc deficiency through depletion of accessible body zinc stores developed during the 35-day study.

This study assessed the level of malarial infection in relation to some epidemiological factors, gravidity and pregnancy period of antenatal clinic attendees of the Federal Medical Centre, Makurdi, Benue State, Nigeria. We also assessed malarial infection in placental blood in relation to gravidity of pregnant women at delivery in the maternity clinic of the same hospital. Thin and thick blood films were prepared for microscopic examination. A questionnaire was administered to each pregnant woman at the antenatal clinic to collect data on educational level, occupation, gravidity, pregnancy period, malaria preventive measures and malaria symptoms. Of the 163 pregnant women examined at the antenatal clinic, 68.3% (111/163) were infected with malaria. Pregnant women that are illiterates (χ2=15.44, P=0.100) and those that are farmers (χ2=9.20, P=0.270) had the highest infection rate with no significant difference respectively. Malarial infection was significantly higher in the multigravidae, 57.6% (34/59) (χ2=5.16, P=0.007) and non-significant in the pregnant women at their third trimester of pregnancy, 60.9% (53/89) (χ2=4.45, P=0.108). Placental malaria was significantly higher in the primigravidae among pregnant women at delivery (χ2=9.33, P=0.000). A significant difference (χ2=33.52, P=0.000) was observed between pregnant women that did not use any malaria preventive methods, 91.2% (31/34) and those that used single, 64.3% (65/101) and combined, 46.4% (13/28) methods of prevention. Malaria remains highly prevalent among antenatal clinics attendees in Makurdi, Nigeria. Combined method of prevention (insecticides treated nets and insecticide spray) yielded good results and its use is advocated in preventing malaria among the pregnant women. PMID:24757507

The dynamic cervical implant (DCI) is a novel motion-preserving concept for the treatment of degenerative cervical disorders. The aim of this prospective clinical study was to validate the concept and analyse clinical and radiological performance of the implant. One hundred seventy-five consecutive patients with degenerative cervical disorders, median age, 47 years, were treated with discectomy and DCI, and followed for 2 years. Clinical outcome was evaluated with the Neck Disability Index (NDI), the SF-12, and visual analogue scale (VAS) assessment of arm and neck pain. Range of motion (ROM) and cervical alignment were analysed using radiographic imaging. All clinical outcome measures--VAS neck and arm pain, NDI, and SF-12 mental and physical component summaries--improved significantly after surgery (each p < 0.001) and remained stable over the whole observation period. The ROM (flexion/extension) at the level treated with DCI was slightly reduced, but no significant changes could be verified at the adjacent levels. Six surgery or device-related adverse events were documented during the study. Good clinical and excellent radiological outcomes demonstrate that DCI is a safe and efficient treatment option in patients with degenerative cervical disorders.

Background: Comparative efficacy of different pharmacist based interventions on glycemic control of type 2 diabetes patients is unclear. This review aimed to evaluate and compare the efficacy of different pharmacist based interventions on clinical outcomes of type 2 diabetes patients. Methods: A systematic search was conducted across five databases from date of database inception to September 2017. All randomized clinical trials evaluating the efficacy of pharmacist based interventions on type 2 diabetes patients were included for network meta-analysis (NMA). The protocol is available with PROSPERO (CRD42017078854). Results: A total of 43 studies, involving 6259 type 2 diabetes patients, were included. NMA demonstrated that all interventions significantly lowered glycosylated hemoglobin (HbA1c) levels compared to usual care, but there was no statistical evidence from this study that one intervention was significantly better than the other for reducing HbA1c levels. Pharmacist based diabetes education plus pharmaceutical care showed maximum efficacy for reducing HbA1c levels [−0.86, 95% CI −0.983, −0.727; p < 0.001]. Pharmacist based diabetes education plus pharmaceutical care was observed to be statistically significant in lowering levels of systolic blood pressure [−4.94; 95%CI −8.65, −1.23] and triglycerides levels [−0.26, 95%CI −0.51, −0.01], as compared to the interventions which involved diabetes education by pharmacist, and for body mass index (BMI) [−0.57; 95%CI −1.25, −0.12] in comparison to diabetes education by health care team involving pharmacist as member. Conclusion: The findings of this review demonstrate that all interventions had a significantly positive effect on HbA1c, but there was no statistical evidence from this study that one intervention was significantly better than the other for achieving glycemic control.Pharmacist based diabetes education plus pharmaceutical care showed maximum efficacy on HbA1c and rest of the clinical outcomes.

Low-level donor-specific HLA-antibodies (HLA-DSA) (i.e. detectable by single-antigen flow beads, but negative by complement-dependent cytotoxicity crossmatch) represent a risk factor for early allograft rejection. The short-term efficacy of an induction regimen consisting of polyclonal anti-T-lymphocyte globulin (ATG) and intravenous immunoglobulins (IvIg) in patients with low-level HLA-DSA is unknown. In this study, we compared 67 patients with low-level HLA-DSA not having received ATG/IvIg induction (historic control) with 37 patients, who received ATG/IvIg induction. The two groups were equal regarding retransplants, HLA-matches, number and class of HLA-DSA. The overall incidence of clinical/subclinical antibody-mediated rejection (AMR) was lower in the ATG/IvIg than in the historic control group (38% vs. 55%; p = 0.03). This was driven by a significantly lower rate of clinical AMR (11% vs. 46%; p = 0.0002). Clinical T-cell-mediated rejection (TCR) was significantly lower in the ATG/IvIg than in the historic control group (0% vs. 50%; p < 0.0001). Within the first year, allograft loss due to AMR occurred in 7.5% in the historic control and in 0% in the ATG/IvIg group. We conclude that in patients with low-level HLA-DSA, ATG/IvIg induction significantly reduces TCR and the severity of AMR, but the high rate of subclinical AMR suggests an insufficient control of the humoral immune response.

Objective To find the best lead exposure assessment marker for children. Methods We recruited 11 children, calculated a cumulative blood lead index (CBLI) for the children, measured their concurrent BLL, assessed their development, and measured their bone lead level. Results Nine of 11 children had clinically significant neurodevelopment problems. CBLI and current blood lead level, but not the peak lead level, were significantly or marginally negatively associated with the full-scale IQ score. Conclusion Lead exposure at younger age significantly impacts a child’s later neurodevelopment. CBLI may be a better predictor of neurodevelopment than are current or peak blood lead levels.

Objective This study aims to evaluate the correlation of changes in serum insulin-like growth factor-1 (IGF-1) levels with the clinical staging of hypoxic-ischemic encephalopathy (HIE) in term newborns. Study Design A prospective study of 29 newborns with HIE (stage I = 15, stage II + III = 14) and 28 healthy term newborns as the control group was performed in the neonatal intensive care unit. IGF-1 levels were obtained within 6 hours after birth from HIE and control groups and again on day 3 from HIE group. HIE was classified using the Sarnat staging I to III. Results IGF-1 levels were significantly lower in the HIE group than in the control group (p = 0.024). It was lower in the HIE stage II to III group compared with HIE stage I group at birth (p < 0.0001) and on day 3 (p = 0.009). The mean IGF-1 levels were significantly higher on day 3 than on day 1 among stage II to III HIE (p = 0.006) and it was inversely correlated with staging (R =  - 0.475, p = 0.009). There was a significant correlation between IGF-1 levels and Apgar score at 5 (R = 0.39, p = 0.042) and 10 minutes (R = 0.38, p = 0.035). Conclusions IGF-1 was lower in HIE and inversely correlated with clinical staging. It was increased with clinical improvement in the subsequent days.

Periodontal disease is the most common multifactorial disease, afflicting a very large proportion of the adult population. Periodontal disease secondarily causes increases in the serum levels of C-reactive protein (CRP) and other markers of inflammation. An increased level of CRP reflects an increased risk for cardiovascular disease. The aim of the current randomized clinical trial was to evaluate the short-term effect of a combination of dipyridamole and prednisolone (CRx-102) on the levels of high-sensitivity (hs)-CRP, proinflammatory markers in blood, and clinical signs of periodontal disease. Fifty-seven patients with >/=10 pockets with probing depths >/=5 mm were randomized into two groups in this masked single-center placebo-controlled study: CRx-102 (n = 28) and placebo (n = 29). hs-CRP levels, inflammatory markers (interleukin [IL]-6, -1beta, -8, and -12, tumor necrosis factor-alpha, and interferon-gamma [IFN-gamma]), bleeding on probing (BOP), and changes in probing depths were evaluated. The subjects received mechanical non-surgical therapy after 42 days, and the study was completed after 49 days. At day 42, the differences in the hs-CRP, IFN-gamma, and IL-6 levels between the two groups were statistically significant (P <0.05), whereas no difference was found for the other inflammatory markers. There was no change in probing depth or BOP between the two groups. The administration of CRx-102 resulted in significant decreases in hs-CRP, IFN-gamma, and IL-6, but it did not significantly change BOP or probing depths.

Objectives Despite increasing interest in individual instrument storage, risk of bacterial cross-contamination of otorhinolaryngology clinic instruments has not been assessed. This study is the first to determine the clinical efficacy and cost-effectiveness of standard high-level disinfection and clinic instrument storage. Methods To assess for cross-contamination, surveillance cultures of otorhinolaryngology clinic instruments subject to standard high-level disinfection and storage were obtained at the start and end of the outpatient clinical workday. Rate of microorganism recovery was compared with cultures of instruments stored in individual peel packs and control cultures of contaminated instruments. Based on historical clinic data, the direct allocation method of cost accounting was used to determine aggregate raw material cost and additional labor hours required to process and restock peel-packed instruments. Results Among 150 cultures of standard high-level disinfected and co-located clinic instruments, 3 positive bacterial cultures occurred; 100% of control cultures were positive for bacterial species ( P < .001). There was no statistical difference between surveillance cultures obtained before and after the clinic day. While there was also no significant difference in rate of contamination between peel-packed and co-located instruments, peel packing all instruments requires 6250 additional labor hours, and conservative analyses place the cost of individual semicritical instrument storage at $97,852.50 per year. Discussion With in vitro inoculation of >200 otorhinolaryngology clinic instruments, this study demonstrates that standard high-level disinfection and storage are equally efficacious to more time-consuming and expensive individual instrument storage protocols, such as peel packing, with regard to bacterial contamination. Implications for Practice Standard high-level disinfection and storage are equally effective to labor-intensive and costly individual instrument storage protocols.

To observe the influence of these complexes on potassium levels in a clinical setting, we investigated the influence of herbal complexes containing licorice on potassium levels. We retrospectively examined the medical records of patients treated with herbal complexes containing licorice from January 1, 2010, to December 31, 2010. We recorded the changes in the levels of potassium, creatinine, and blood urea nitrogen and examined the differences between before and after herbal complexes intake using a paired t-test. In addition, we investigated the prevalence of hypokalemia among these patients and reviewed such patients. We identified 360 patients who did not show significant changes in the levels of potassium and creatinine (P = 0.815, 0.289). We observed hypokalemia in 6 patients. However, in 5 patients, the hypokalemia did not appear to be related to the licorice. Thus, we could suggest that herbal complexes containing licorice do not significantly influence the potassium levels in routine clinical herbal therapies. However, we propose that follow-up examination for potassium levels is required to prevent any unpredictable side effects of administration of licorice in routine herbal medicine care. PMID:25045393

To examine the changes in 25-hydroxyvitamin D 3 [25-(OH)D 3 ] level in children with Henoch-Schönlein purpura (HSP) and its clinical significance. A total of 92 HSP children were included in this study, and were divided into HSP nephritis (HSPN) group (31 cases) and HSP group (61 cases) based on the presence or absence of HSPN. Alternatively, the patients were divided into purpura alone group (22 cases), purpura with joint symptoms group (joint symptom group, 24 cases), purpura with gastrointestinal symptoms group (gastrointestinal symptom group, 20 cases), and purpura with joint and gastrointestinal symptoms (mixed group, 26 cases) based on their clinical symptoms. In addition, 42 healthy children were selected as healthy control group. The level of 25-(OH)D 3 in each group was measured using enzyme-linked immunoassay. The 25-(OH)D 3 level in the HSP and HSPN groups was significantly lower than that in the healthy control group (P<0.05), and the 25-(OH)D 3 level in the HSPN group was significantly lower than that in the HSP group (P<0.05). Although there was no significant difference in the 25-(OH)D 3 level between the joint symptom, gastrointestinal symptom, and mixed groups (P=0.22), the 25-(OH)D 3 level in the three groups was all significantly lower than that in the purpura alone group (P<0.05). The level of 25-(OH)D 3 is reduced in children with HSP, particularly those with HSPN or with joint and gastrointestinal symptoms. Therefore, the reduction in 25-(OH)D 3 level may serve as a predictor of whether HSP is associated with other impairments.

Because of the highly stigmatized nature of abortion care delivery and the restriction of abortion provision in most states, little is known about abortion care quality beyond procedural safety. This study examined which aspects of abortion care contributed to patient experiences. Data from a prospective, observational study of 9087 women aged 16 to 44 years, from 22 clinics across California, who responded to a postprocedure survey, were analyzed using mixed-effects logistic regression. Patient experience scores were very high (mean overall satisfaction = 9.4 [0-10 scale]) for all clinicians trained in abortion provision (physicians, nurse practitioners, nurse-midwives, and physician assistants). Multiple patient factors (pain rating, expectations of care, sociodemographics) and clinic-level factors (timely care, treatment by clinicians and staff) were significantly associated with patient experience. Study findings demonstrated that clinic environment, treatment by clinical staff, and managed pain levels contributed to a patient's experience of abortion care, whereas clinician type was not significantly associated.

Normal Morning Melanin-Concentrating Hormone Levels and No Association with Rapid Eye Movement or Non-Rapid Eye Movement Sleep Parameters in Narcolepsy Type 1 and Type 2.

Other than hypocretin-1 (HCRT-1) deficiency in narcolepsy type 1 (NT1), the neurochemical imbalance of NT1 and narcolepsy type 2 (NT2) with normal HCRT-1 levels is largely unknown. The neuropeptide melanin-concentrating hormone (MCH) is mainly secreted during sleep and is involved in rapid eye movement (REM) and non-rapid eye movement (NREM) sleep regulation. Hypocretin neurons reciprocally interact with MCH neurons. We hypothesized that altered MCH secretion contributes to the symptoms and sleep abnormalities of narcolepsy and that this is reflected in morning cerebrospinal fluid (CSF) MCH levels, in contrast to previously reported normal evening/afternoon levels. Lumbar CSF and plasma were collected from 07:00 to 10:00 from 57 patients with narcolepsy (subtypes: 47 NT1; 10 NT2) diagnosed according to International Classification of Sleep Disorders, Third Edition (ICSD-3) and 20 healthy controls. HCRT-1 and MCH levels were quantified by radioimmunoassay and correlated with clinical symptoms, polysomnography (PSG), and Multiple Sleep Latency Test (MSLT) parameters. CSF and plasma MCH levels were not significantly different between narcolepsy patients regardless of ICSD-3 subtype, HCRT-1 levels, or compared to controls. CSF MCH and HCRT-1 levels were not significantly correlated. Multivariate regression models of CSF MCH levels, age, sex, and body mass index predicting clinical, PSG, and MSLT parameters did not reveal any significant associations to CSF MCH levels. Our study shows that MCH levels in CSF collected in the morning are normal in narcolepsy and not associated with the clinical symptoms, REM sleep abnormalities, nor number of muscle movements during REM or NREM sleep of the patients. We conclude that morning lumbar CSF MCH measurement is not an informative diagnostic marker for narcolepsy. © 2017 American Academy of Sleep Medicine

Determining inflammatory activity is crucial for assessing disease activity and for tailoring therapy in patients with Crohn׳s disease (CD). This study aimed to evaluate adipocytokine levels in patients with CD and to determine whether they can serve as surrogate markers for disease activity. Serum samples and information regarding the clinical features of patients in the CD Network Project registry were collected from March 2009 to February 2012. Patients with CD and disease duration of at least 2 years were enrolled in this study. Fasting serum leptin, adiponectin, obestatin and ghrelin levels were measured, and their correlation with clinical features of the patients was analyzed. Serum adipocytokine levels were evaluated according to disease activity as determined by CD activity index score. A total of 153 patients with CD were included. Serum ghrelin levels negatively correlated with patient age (P = 0.041) and age at diagnosis (P = 0.017), and positively correlated with C-reactive protein (CRP) levels (P = 0.017). Multiple regression analysis showed that serum ghrelin levels were related only to CRP levels (P = 0.032). Like ghrelin, serum leptin levels were also related to CRP levels (P < 0.001). Obestatin and adiponectin levels were not related to CRP levels. Serum adipocytokine levels did not significantly differ across different disease locations or behaviors. Serum ghrelin levels were significantly lower in patients with CD with a history of surgery than in those without (P = 0.007). Serum ghrelin and leptin levels may be useful as surrogate markers for disease activity in patients with CD. Copyright © 2017 Southern Society for Clinical Investigation. Published by Elsevier Inc.

The focused assessment with sonography for trauma (FAST) examination has become the standard of care for rapid evaluation of trauma patients. Extended FAST (eFAST) is the use of ultrasonography for the detection of pneumothorax (PTX). The exact sensitivity and specificity of eFAST detecting traumatic PTX during practical "real-life" application is yet to be investigated. This is a retrospective review of all trauma patients with a diagnosis of PTX, who were treated at a large level 1 urban trauma center from March 2013 through July 2014. Charts were reviewed for results of imaging, which included eFAST, chest X-ray, and CT scan. The requirement of tube thoracostomy and mechanism of injury were also analyzed. A total of 369 patients with a diagnosis of PTX were identified. A total of 69 patients were excluded, as eFAST was either not performed or not documented, leaving 300 patients identified with PTX. A total of 113 patients had clinically significant PTX (37.6%), requiring immediate tube thoracostomy placement. eFAST yielded a positive diagnosis of PTX in 19 patients (16.8%), and all were clinically significant, requiring tube thoracostomy. Chest X-ray detected clinically significant PTX in 105 patients (92.9%). The literature on the utility of eFAST for PTX in trauma is variable. Our data show that although specific for clinically significant traumatic PTX, it has poor sensitivity when performed by clinicians with variable levels of ultrasound training. We conclude that CT is still the gold standard in detecting PTX, and clinicians performing eFAST should have adequate training.

The study aimed to explore measurable compassion competence among nurses and to examine the relationships between nurses' compassion competence and levels of compassion satisfaction, compassion fatigue and secondary traumatic stress. Compassion is a vital asset in the nursing profession. It is necessary to explore whether compassion competence is a factor influencing professional quality of life. This study utilized a multicenter descriptive cross-sectional survey. Data were collected from 680 nurses. Professional quality of life based on nurses' general characteristics showed a significant difference in the subjects' age, marital status, education, and total clinical experience. In addition, compassion competence had a significant positive correlation with compassion satisfaction and STS, whereas it had a significant negative correlation with burnout. Compassion competence was a factor influencing compassion satisfaction and burnout in professional quality of life. Our study included nurses with at least 1 year of clinical experience in a single cultural area, which limits its widespread applicability. To improve generalizability, future studies should include clinical nurses of various races, working in diverse cultural areas and with various levels of experience (including entry-level nurses and nursing students). Compassion competence of clinical nurses was a predictive factor for professional quality of life. Hospital administrators, nurse leaders and policy makers should develop and adopt nurse-retaining strategies that focus on improving nurses' compassion competence in order to reduce their burnout. We recommend the development of educational programmes to improve nurses' compassion competence and thereby enhance their professional quality of life. © 2016 International Council of Nurses.

INTRODUCTION Ezetimibe (EZ) is a selective cholesterol absorption inhibitor approved for use in Canada. The effect and tolerability of EZ among patients was evaluated in the clinical setting of a specialty cardiovascular risk reduction clinic at the University of Alberta Hospital, Edmonton, Alberta. PATIENTS AND METHODS All patients 18 years of age or older who were prescribed EZ were included, unless they failed to take EZ for a minimum of two weeks, did not have baseline and on-EZ low-density lipoprotein cholesterol (LDL-C) levels, or had concomitant lipid-lowering drugs or dosages changed within one month of starting EZ. RESULTS Eighty-four patients (mean age 57.9 years) were included. By Framingham risk calculation, 71.4% were found to be high-risk patients, 13.1% moderate-risk patients and 15.5% low-risk patients; 66.7% of patients had prior cardiovascular events. On EZ, the mean reductions were: total cholesterol level 1.11 mmol/L (16.5%); LDL-C level 1.01 mmol/L (22.3%); high-density lipoprotein cholesterol level 0.06 mmol/L (4.6%); and ratio of total cholesterol level to high-density lipoprotein cholesterol level 0.68 mmol/L (12.8%); all were statistically significant (P<0.001). Results were similar when stratified by primary (n=28) versus secondary (n=56) prevention. Patients on EZ monotherapy (n=34) had mean LDL-C reductions of 1.03 mmol/L (20.5%) compared with 1.19 mmol/L (30.1%) or 0.95 mmol/L (22.5%), where EZ was added to low-dose or high-dose statins (P<0.01 for all). On EZ, 30 patients (35.7%) achieved previously unattainable target LDL-C levels. Four patients discontinued the drug due to side effects. CONCLUSIONS EZ is safe and effective in high-risk patients treated in the clinical setting of a cardiovascular risk reduction clinic. A mean LDL-C reduction of 1 mmol/L (20% to 30%) in all patient subgroups is consistent with previous clinical trial results. The significant reduction in LDL-C (mean 22.5%) observed in the EZ plus high-dose statin subgroup provides clinical evidence for use of this medication beyond published studies. PMID:16971979

Nurses are one of the most influential factors in overcoming the main challenges faced by health systems throughout the world. Every health system should, hence, empower nurses in clinical judgment and decision-making skills. This study evaluated the effects of implementing Tanner's reflection method on clinical decision-making of nurses working in an intensive care unit (ICU). This study used an experimental, pretest, posttest design. The setting was the intensive care unit of Amin Hospital Isfahan, Iran. The convenience sample included 60 nurses working in the ICU of Amin Hospital (Isfahan, Iran). This clinical trial was performed on 60 nurses working in the ICU of Amin Hospital (Isfahan, Iran). The nurses were selected by census sampling and randomly allocated to either the case or the control group. Data were collected using a questionnaire containing demographic characteristics and the clinical decision-making scale developed by Laurie and Salantera (NDMI-14). The questionnaire was completed before and one week after the intervention. The data were analyzed using SPSS 21.0. The two groups were not significantly different in terms of the level and mean scores of clinical decision-making before the intervention (P = 0.786). Based on the results of independent t-test, the mean score of clinical decision-making one week after the intervention was significantly higher in the case group than in the control group (P = 0.009; t = -2.69). The results of Mann Whitney test showed that one week after the intervention, the nurses' level of clinical decision-making in the case group rose to the next level (P = 0.001). Reflection could improve the clinical decision-making of ICU nurses. It is, thus, recommended to incorporate this method into the nursing curriculum and care practices. Copyright © 2018.

O’Connor, Michael Glenn; Thomsen, Kelly; Brown, Rebekah F.; Laposata, Michael; Seegmiller, Adam

2016-01-01

Background Airway inflammation is a significant contributor to the morbidity of cystic fibrosis (CF) disease. One feature of this inflammation is the production of oxygenated metabolites, such as prostaglandins. Individuals with CF are known to have abnormal metabolism of fatty acids, typically resulting in reduced levels of linoleic acid (LA) and docosahexaenoic acid (DHA). Methods This is a randomized, double-blind, cross-over clinical trial of DHA supplementation with endpoints of plasma fatty acid levels and prostaglandin E metabolite (PGE-M) levels. Patients with CF age 6 to 18 years with pancreatic insufficiency were recruited. Each participant completed 3 four-week study periods: DHA at two different doses (high dose and low dose) and placebo with a minimum 4 week wash-out between each period. Blood, urine, and exhaled breath condensate (EBC) were collected at baseline and after each study period for measurement of plasma fatty acids as well as prostaglandin E metabolites. Results Seventeen participants were enrolled, and 12 participants completed all 3 study periods. Overall, DHA supplementation was well tolerated without significant adverse events. There was a significant increase in plasma DHA levels with supplementation, but no significant change in arachidonic acid (AA) or LA levels. However, at baseline, AA levels were lower and LA levels were higher than previously reported for individuals with CF. Urine PGE-M levels were elevated in the majority of participants at baseline, and while levels decreased with DHA supplementation, they also decreased with placebo. Conclusions Urine PGE-M levels are elevated at baseline in this cohort of pediatric CF patients, but there was no significant change in these levels with DHA supplementation compared to placebo. In addition, baseline plasma fatty acid levels for this cohort showed some difference to prior reports, including higher levels of LA and lower levels of AA, which may reflect changes in clinical care, and consequently warrants further investigation.

AIM To evaluate the effect of silymarin on the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma glutamyl transpeptidase (γGT) in patients with liver diseases. METHODS A systematic review with meta-analysis of ramdomized and controlled clinical trials was performed, evaluating the effects of sylimarin in patients with hepatic diseases, published by January 31, 2016. Clinical trials were sought on the basis of The Cochrane Central Register of Controlled Trials in the Cochrane Library, PubMed/Medline, Scopus, Web of Science, Lilacs and Clinical Trials. The trials with adult and elderly patients of both sexes, with Liver Diseases who took oral silymarin supplementation, as extract or isolated, as well as Silymarin combined with other nutrients, were included. The trials should provide information about the intervention, such as dosages and detailing of the product used, besides the mean and standard deviation of serum levels of ALT, AST and γGT of the baseline and at the end of the intervention. RESULTS An amount of 10904 publications were identified. From those, only 17 were included in the systematic review and 6 in the meta-analysis, according to the used selection criteria. In this meta-analysis, the results indicated a reduction of 0.26 IU/mL (95%CI: -0.46-0.07, P = 0.007) at the level of ALT and 0.53 IU/mL (95%CI: -0.74-0.32, P = 0.000) at the serum levels of AST after using the silymarin, both, statistically significant, but with no clinical relevance. There was no significant change in the γGT levels. Subgroup analyzes were also performed for the biochemical markers in relation to the type of intervention, whether silymarin isolated or associated with other nutrients and the time of intervention (whether ≥ 6 mo or < 6 mo). Significant differences were not found. The evaluated studies presented a high degree of heterogeneity and low methodological quality in the carried out analysis. CONCLUSION Silymarin minimally reduced, but without clinical relevance, the serum levels of ALT and AST. It is necessary to carry out studies with more appropriate methodological designs.

The aims of this study are (1) to describe issues related to recruitment of mothers participating in a clinical trial of transmission of mutans streptococci (MS) from mother to child in Bauru, Brazil and (2) to perform cross-cultural and temporal comparisons of levels of infection of the MS in mothers of Bauru. A total of 1422 mothers were visited at their domiciles. Cutoff levels for the MS were established at ≥105 CFU/mL saliva. The main reason for a mother not enrolling was not being highly infected by the MS, yet 76% of mothers presented with levels ≥105 CFU/mL saliva. Recent studies in industrialized countries showed a negative coefficient for linear tests indicating significant decline overtime in the levels of MS in mothers. Intercountry comparisons for mothers' salivary levels of the MS with the Bauru study as the reference revealed significant differences with studies conducted in the last two decades. PMID:20827385

The accuracy of analogue and especially digital intra-oral radiography in assessing interdental bone level needs further documentation. The aim of this study was to compare clinical and radiographic bone level assessment to intra-surgical bone level registration (1) and to identify the clinical variables rendering interdental bone level assessment inaccurate (2). The study sample included 49 interdental sites in 17 periodontitis patients. Evaluation methods included vertical relative probing attachment level (RAL-V), analogue and digital intra-oral radiography and bone sounding without and with flap elevation. The latter was considered the true bone level. Five examiners evaluated all radiographs. Significant underestimation of the true bone level was observed for all evaluation methods pointing to 2.7 mm on average for analogue radiography, 2.5 mm for digital radiography, 1.8 mm for RAL-V and 0.6 mm for bone sounding without flap elevation (p < 0.001). Radiographic underestimation of the true bone level was higher in the (pre)molar region (p ≤ 0.047) and increased with defect depth (p < 0.001). Variation between clinicians was huge (range analogue radiography 2.2-3.2 mm; range digital radiography 2.1-3.0 mm). All evaluation methods significantly underestimated the true bone level. Bone sounding was most accurate, whereas intra-oral radiographs were least accurate. Deep periodontal defects in the (pre)molar region were most underrated by intra-oral radiography. Bone sounding had the highest accuracy in assessing interdental bone level.

Home-based sampling is a strategy to enhance uptake of sexually transmissible infection (STI) screening. This review aimed to compare the screening uptake levels of home-based self-sampling and clinic-based specimen collection for STIs (chlamydia (Chlamydia trachomatis), gonorrhoea (Neisseria gonorrhoeae) and trichomoniasis) in females aged 14-50 years. Acceptability and effect on specimen quality were determined. Sixteen electronic databases were searched from inception to September 2012. Randomised controlled trials (RCTs) comparing the uptake levels of home-based self-sampling and clinic-based sampling for chlamydia, gonorrhoea and trichomoniasis in females aged 14-50 years were eligible for inclusion. The risk of bias in the trials was assessed. Risk ratios (RRs) for dichotomous outcomes were meta-analysed. Of 3065 papers, six studies with seven RCTs contributed to the final review. Compared with clinic-based methods, home-based screening increased uptake significantly (P=0.001-0.05) in five trials and was substantiated in a meta-analysis (RR: 1.55; 95% confidence interval: 1.30-1.85; P=0.00001) of two trials. In three trials, a significant preference for home-based testing (P=0.001-0.05) was expressed. No significant difference was observed in specimen quality. Sampling was rated as easy by a significantly higher number of women (P=0.01) in the clinic group in one trial. The review provides evidence that home-based testing results in greater uptake of STI screening in females (14-50 years) than clinic-based testing without compromising quality in the developed world. Home collection strategies should be added to clinic-based screening programs to enhance uptake.

Background and aims Plasma rich in growth factors (PRGF) is a concentrated suspension of growth factors, which is used to promote periodontal tissue regeneration. The aim of this randomized, controlled, clinical trial was to evaluate of the treatment of grade II mandibular molar furcation involvement using autogenous bone graft with and without PRGF. Materials and methods In this double-blind clinical trial, thirty mandibular molars with grade II furcation involvement in 30 patients were selected. The test group received bone graft combined with PRGF, while the control group was treated with bone graft only. Clinical parameters included clinical probing depth (CPD), vertical clinical attachment level (V-CAL), horizontal clinical attachment level (H-CAL), location of gingival margin (LGM), surgically exposed horizontal probing depth of bony defect (E-HPD), vertical depth of bone crest (V-DBC), vertical depth of the base of bony defect (V-DBD), and length of the intrabony defect (LID). After six months, a re-entry surgery was performed. Data were analyzed by SPSS 14, using Kolmogorov, Mann-Whitney U, and paired t-test. Results After 6 months, both treatment methods led to significant improvement in V-CAL and H-CAL and significant decreases in CPD, E-HPD, V-DBD and LID; there was no significant difference in LGM and V-DBC in any of the treated groups compared to the baseline values. Also, none of the parameters showed significant differences between the study groups. Conclusion Although autogenous bone grafts, with or without PRGF, were successful in treating grade II furcation involvement, no differences between the study groups were observed. PMID:23486928

To evaluate the effectiveness of a multibenefit mouthrinse containing 0.05% cetylpyridinium chloride (CPC) and 0.025% sodium fluoride in reducing volatile sulfur compound (VSC) levels and total cultivable salivary bacteria, at both 4 h and overnight. In vitro analysis of efficacy was performed using saliva-coated hydroxyapatite disc substrates first treated with the mouthrinse, then exposed to whole human saliva, followed by overnight incubation in air-tight vials. Headspace VSC was quantified by gas chromatography (GC). A clinical evaluation was conducted with 14 subjects using a crossover design. After a seven-day washout period, baseline clinical measurement of VSC was performed by GC analysis of mouth air sampled in the morning prior to eating, drinking or performing any oral hygiene. A 10 mL saline rinse was used to sample and enumerate cultivable salivary bacterial levels via serial dilution and plating. Subjects were instructed to use the treatment rinse twice daily in combination with a controlled brushing regimen. After one week the subjects returned in the morning prior to eating, drinking or performing oral hygiene to provide samples of overnight mouth air and salivary bacteria. The subjects were then immediately rinsed with the test product, and provided additional mouth air and saliva rinse samples 4 h later. A multibenefit rinse containing 0.05% CPC and 0.025% sodium fluoride was found to reduce VSC in vitro by 52%. The rinse also demonstrated a significant clinical reduction in breath VSC (p < 0.05) of 55.8% at 4 h and 23.4% overnight relative to baseline VSC levels. At both time points, the multibenefit rinse was more effective than the control; this difference was statistically significant at the overnight time point (p < 0.05). Total cultivable salivary bacteria levels were also reduced significantly (p < 0.05) at 4 h and overnight by this mouthrinse compared to baseline levels and the control. A multibenefit mouthrinse was shown to reduce in vitro VSC levels via headspace analysis and clinically at the 4 h and overnight time points. A significant reduction in total cultivable salivary bacteria was also observed at all time points, supporting the VSC data.

Background Medical science is perceived as a stressful educational career, and medical students experience monstrous stress during their undergraduate studies, internship, and residency training, which affects their cognitive function, practical life, and patient care. In the present study, an assessment of the prevalence of self-perceived stress among new medical graduates during their internship training has been performed, and correlations of self-perceived stress with sex, marital status, and clinical rotations have been evaluated. Patients and methods Interns of the King Khalid, King Abdulaziz, and King Fahd University hospitals in Saudi Arabia were invited to complete a stress inventory known as the Kessler 10, which is used for stress measurement. Apart from stress evaluation, the questionnaire collected personal data, such as age, sex, and marital status, in addition to information relevant to hospital training, assigned duties, and clinical training rotations. Results Our results showed that nearly 73.0% of interns were under stressed conditions. Most of the interns were affected by a severe level of stress (34.9%), followed by mild (19.3%) and moderate (18.8%) levels of stress. The stress level was significantly higher (84.0%) among female interns in comparison with male interns (66.5%) (odds ratio =2.64; confidence interval =1.59–4.39; P<0.0002). There were statistically significant differences between the percentages of male and female interns (P≤0.047) at mild, moderate, and severe stress levels. Marital status had no role in causing stress. The highest stress level was reported by interns during the clinical rotations of medicine (78.8%), followed by surgery (74.7%), pediatrics (72.4%), obstetrics and gynecology (70.1%), and emergency (58.3%). The prevalence of stress among the interns and their corresponding clinical rotations in all three hospitals had significant linear correlations (r≥0.829, P≤0.041). Conclusion We found a significantly high level of stress among the medical interns. High stress may have negative effects on cognitive functioning, learning, and patient care. Hence, medical interns need support and subsequent interventions to cope with stress. PMID:25328389

Aims. Previous evidence has proved that interleukin-31 (IL-31) and interleukin-33 (IL-33) can be potential markers in some cancers' formulation. We aimed to determine the potential role of IL-31 and IL-33 in prognosis of endometrial cancer patients. Methods. Serum samples were collected from 160 patients with endometrial cancer and 160 healthy controls. The ELISA kits (Raybio® Systems) specific for human IL-31 and human IL-33 were used. Serum levels of tumor markers (CEA, CA-125, and CA19-9) were measured by chemiluminescence immunoassay. A two-side P value < 0.05 was indicated to be significant. Results. Serum levels of IL-31 and IL-33 in patients were significantly elevated compared to those of healthy controls. The interleukin levels were also related to clinical characteristics, including tumor stages, depth of invasion, and existence of node metastases and distant metastases. The sensitivity and specificity of IL-31 and IL-33 were higher than the counterparts of tumor markers, both separately and in combination of IL-31, IL-33, and the clinical markers. Conclusions. This report is the first one mentioning the possible association between serum IL-31 and IL-33 and endometrial cancer. With their sensitivity and specificity, the interleukins may be useful biomarkers for endometrial cancer's prognosis. PMID:27340318

This study aimed to investigate the expression levels of L-DOPA decarboxylase (DDC) mRNA and protein in laryngeal cancer, and to determine the clinical significance of DDC in diagnosis and prognosis of laryngeal cancer. Total RNA was isolated from 106 tissue samples surgically removed from 53 laryngeal cancer patients. A quantitative real-time polymerase chain reaction (RT-PCR) methodology based on SYBR Green I fluorescent dye was developed for the quantification of mRNA levels. In addition, Western Blot analysis was performed to detect the expression level of DDC protein. DDC mRNA expression in both primary (P= 0. 000) and recurrent (P=0. 033) laryngeal cancer samples downregulated significantly compared with their nonmalignant counterparts. Moreover, expression of DDC mRNA was not associated with age and histologic grade, but the significantly decreased mRNA were correlated with early TMN stage (P=0. 021). Additionally, DDC protein was detected in both cancerous and noncancerous tissues. Expression levels of DDC may play a vital role in the progression of laryngeal cancer, which can be served as a promising biomarker for the future clinical management of laryngeal cancer patients.

Levels of serum immunoglobulin E (IgE) specific for the house dust mites (HDMs) Dermatophagoides farinae (DF) and Dermatophagoides pteronyssinus (DP) in 58 cats with clinical signs suggestive of atopic dermatitis (allergic dermatitis cats), 52 cats with no history of allergic or immunological disease (nonallergic cats) and 26 specific pathogen-free (SPF) cats were measured using a monoclonal anti-IgE enzyme-linked immunosorbent assay. Reactivity to both native and reduced HDM allergens was compared. SPF cats had significantly lower levels of HDM-specific serum IgE than cats with allergic dermatitis and nonallergic cats. The difference in levels of HDM-specific IgE in the serum of cats with allergic dermatitis and nonallergic cats was significant for native DF allergen, but not for native DP allergen or reduced HDM allergens. The results suggest that DF in its native form may be a significant allergen in cats with allergic dermatitis. The clinical relevance of these reactions, however, remains to be proven.

Recent research has highlighted the role of implicative dilemmas in a variety of clinical conditions. These dilemmas are a type of cognitive conflict, in which different aspects of the self are countered in such a way that a desired change in a personal dimension (eg, symptom improvement) may be hindered by the need of personal coherence in another dimension. The aim of this study was to summarize, using a meta-analytical approach, the evidence relating to the presence and the level of this conflict, as well as its relationship with well-being, in various clinical samples. A systematic review using multiple electronic databases found that out of 37 articles assessed for eligibility, nine fulfilled the inclusion criteria for meta-analysis. Random effects model was applied when computing mean effect sizes and testing for heterogeneity level. Statistically significant associations were observed between the clinical status and the presence of dilemmas, as well as level of conflict across several clinical conditions. Likewise, the level of conflict was associated with symptom severity. Results highlighted the clinical relevance and the transdiagnostic nature of implicative dilemmas. PMID:26675503

The present study was carried out to evaluate the effect of 1.2% simvastatin gel as local drug delivery (LDD) system on Gingival Crevicular Fluid (GCF) Interleukin -6 (IL-6) and Interleukin-8 (IL-8) levels in chronic periodontitis patients, in addition to scaling and root planing (SRP). A total of 46 chronic periodontitis patients were equally divided into two groups. Group I patients were treated by SRP; Group II patients were treated by SRP followed by LDD of 1.2% simvastatin (SMV) gel. Plaque index (PI), Gingival index(GI), Sulcus Bleeding Index (SBI), Probing pocket depth (PPD) and Relative clinical attachment level (CAL) were recorded & GCF samples were collected at baseline (0day) and at 45th day from both the groups. The collected GCF samples were analysed for IL-6 and IL-8 levels with enzyme-linked immunosorbent assay (ELISA). Both the groups showed significant reduction in all the clinical parameters scores and IL-6 and IL-8 levels after non-surgical periodontal therapy (SRP for group I/SRP+1.2% SMV gel for group II) in contrast to baseline values. However, a greater reduction was observed in group II. A non-significant positive correlation was observed between clinical parameters and IL-6 and IL-8 levels except at baseline, a significant correlation was observed between PPD &IL 6 levels in group II. In adjunct to SRP, 1.2% Simvastatin gel acts as an effective local drug delivery agent for the management of chronic periodontitis. Copyright © 2017 Elsevier Ltd. All rights reserved.

Many studies of human subjects have demonstrated the utility of assessing serum levels of endothelin-1 (ET-1) and big ET-1 as clinical biomarkers in cardiopulmonary and neoplastic diseases. In this study we explored the feasibility of using serum big ET-1 as a reliable veterinary marker in dogs with various cardiopulmonary and neoplastic diseases. Serum big ET-1 levels were measured by ELISA in dogs with cardiopulmonary (n=21) and neoplastic diseases (n=57). Dogs exhibiting cardiopulmonary disease were divided into two groups based on the velocity of tricuspid valve regurgitation (3.0>m/s) measured by ultrasound: without and with pulmonary hypertension. Big ET-1 levels for the dogs with the diseases were compared with levels in normal healthy dogs (n=17). Dogs with cardiopulmonary disease (4.6±4.6 pmol/l) showed a significantly (P<0.01) higher level of big ET-1 than healthy control dogs (1.1±0.53 pmol/l). Serum levels in the dogs with pulmonary hypertension (6.2±5.3 pmol/l) were significantly (P<0.01) higher than those without pulmonary hypertension (2.0±0.6 pmol/l). Dogs with hemangiosarcoma (5.6±2.2 pmol/l), adenocarcinoma (2.0±1.8 pmol/l), histiocytic sarcoma (3.3±1.9 pmol/l), chondrosarcoma or osteosarcoma (3.0±1.6 pmol/l) and hepatocellular carcinoma (2.7±1.8 pmol/l) showed significantly (P<0.05) higher levels than healthy control dogs. These findings point to the potential of serum big ET-1 as a clinical marker for cardiopulmonary and neoplastic diseases in dogs. Copyright © 2014 The Authors. Published by Elsevier Inc.

To develop and test a novel extracapsular technique, TightRope CCL technique (TR), and compare its 6-month clinical outcomes to tibial plateau leveling osteotomy (TPLO) in dogs with cranial cruciate ligament (CCL) deficiency. Prospective clinical cohort study. Medium, large, and giant breed dogs (n=47) with CCL deficiency. Before clinical use, TR was evaluated by mechanical testing and the surgical technique was developed and evaluated in canine cadavers. For the clinical study, dogs were assigned to either TR (n=24) or TPLO (n=23) groups and the assigned technique performed after arthroscopic assessment and treatment of joint pathology. Postoperative management was standardized for both groups. Outcome measures were performed immediately postoperatively and up to 6 months after surgery and included complication types and rate, subjective measurement of cranial drawer and tibial thrust, subjective assessment of radiographic progression of osteoarthritis (OA), and function using a validated client questionnaire (6 months only). TR with a fiber tape suture had superior mechanical properties for creep, stiffness, yield load, and load at failure. Duration of anesthesia, total surgical time, and stabilization procedure (TR versus TPLO) were all significantly (P<.001) shorter for TR compared with TPLO. Complications requiring further treatment occurred in 12.5% of TR cases and 17.4% of TPLO cases. No significant differences were noted between groups for cranial tibial thrust, but cranial drawer was significantly (P<.05) lower in TR stifles at all postoperative time points. No significant differences were noted between groups for radiographic OA scores. No statistically or clinically significant differences were noted between TR and TPLO for scores for each of the client questionnaire categories. TR resulted in 6-month outcomes that were not different than TPLO in terms of radiographic progression of OA and client-evaluated level of function. TR was associated with shorter anesthesia and surgery times as well as a lower complication rate. The TR technique is safe and effective and can be considered an appropriate surgical option as part of the overall treatment plan for CCL deficiency in dogs.

Retroillumination photography analysis (RPA) provides an objective assessment of the number and distribution of guttae in Fuchs corneal dystrophy. Here, we assess its correlation with clinical grading using slit-lamp biomicroscopy across varying levels of severity. Retroillumination photographs were conducted for 95 affected corneas with slit-lamp flash photography after pupillary dilation. Individual guttae were counted manually and the position of individual points recorded. Clinical grading using the Krachmer scale was documented for each eye during examination, and regression analyses were performed to identify the strength of association with number of guttae. We assessed range at each stage of clinical grading and used the Mann-Whitney U test to assess whether clinical grading levels demonstrated successively higher numbers of guttae. Krachmer score ranged from 1 to 5, with mean of 2.6. Mean numbers of guttae at each level of severity were 289 (1+), 999 (2+), 2669 (3+), 5474 (4+), and 7133 (5+). Each stage demonstrated significantly higher numbers of guttae than its preceding level except from 4+ to 5+ (P = 0.30), consistent with the definition of 4+ as the highest level defined by the presence of guttae. Higher levels of clinical grading were associated with larger ranges of guttae (P < 0.01). A linear regression model resulted in a strong fit between RPA and Krachmer score (r = 0.81). In this largest study of RPA data and comparison with subjective clinical grading of Fuchs dystrophy severity, RPA correlates strongly and demonstrates enhanced definition of severity at advanced stages of disease.

The serum Krebs von der Lungen-6 (KL-6) level is a useful marker correlated with the severity of various interstitial lung diseases. There have been few reports about the clinical characteristics of organizing pneumonia (OP) associated with the serum KL-6 levels. This study was performed to determine whether the serum KL-6 levels can help determine the optimal treatment for OP. Patients diagnosed with OP by clinical, radiological and histopathological findings were retrospectively reviewed. The OP patients were classified into two groups based on their serum KL-6 levels: normal KL-6 and high KL-6 groups. The two groups were compared with regard to their clinical and radiological data and therapeutic response one month after the start of treatment. The clinical records of twenty-two patients diagnosed with OP were reviewed. The serum KL-6 level was elevated in 11 of the 22 patients. There were no obvious differences in the clinical data between the two groups, although patients in the normal KL-6 group tended to have a fever. There were no significant differences in the chest X-ray (CXR) score or computed tomography (CT) score between the two groups. The CXR scores were correlated with the serum KL-6 levels. At 1 month after the diagnosis, 11 patients who needed treatment with prednisolone were included in the high KL-6 group. Patients with normal KL-6 levels showed lower CXR and CT scores. The serum KL-6 level on admission is a useful marker to judge the need for corticosteroid treatment in OP patients.

To investigate the expression of 5-hydroxymethylcytosine (5hmC) in bladder urothelial carcinoma (UC) and its clinical significance. The expression of 5hmC in 21 cases of UC tissues and pericarcinous urinary tract epithelium was detected by immunohistochemical staining. Then the expression of 5hmC in the surgical resection of UC tissues in 92 cases was also surveyed. Non parametric U Mann-Whitney test was used to analyze the correlation between 5hmC expression and clinical data. Single factor survival analysis was performed by Kaplan-Meier test. The expression of 5hmC in normal urinary tract epithelium and UC tissues was significantly different, but there was no significant difference in the expression of 5hmC between low and high grades of UC tissues as well as between different TNM grades. Kaplan-Meier single factor survival analysis showed that there was no significant correlation between the 5hmC expression level and the survival rate or the recurrence-free survival of UC patients. The expression level of 5hmC in UC tissues is significantly lower than that in pericarcinous urinary tract epithelium. There is no correlation between the 5hmC expression and the progression, prognosis and recurrence of UC.

To investigate the clinical significance of interleukin-17 (IL-17) level in patients with extranodal NK/T-cell lymphoma(ENKTL). Eighty patients with nasal ENKTL who received radiotherapy, chemotherapy or radiotherapy combined with chemotherapy from January 2011 to January 2012 were enrolled in the study. Eighty healthy volunteers were selected as the controls (control group). About 5 ml of peripheral blood was collected from all patients and controls. IL-17 level was determined by ELISA. The age, sex, ECOG score, B symptoms, LDH level, lymph node involvment, Ann Arbor stage, IPI, KPI, peripheral blood lymphocyte and lymph node metastasis, number of lymphocytes and monocytes in peripheral blood were recorded. All patients were followed up for 3 year progression-free survival (PFS) and overall survival (OS). The average IL-17 level in patients with ENKTL was 6.48 pg/ml and the average concentration of IL-17 in control group was 0.56 pg/ml (P<0.01). The level of IL-17 in patients with B-symptoms and lymph node involvement was significantly higher than that in the control group. The differences in IL-17 level were not statistically significant among patients with different age, sex, ECOG, LDH, Ann Arbor stage, IPI, KPI, lymphocyte count and monocyte cell count. The sensitivity and specificity of IL-17 were 74.5% and 73.7% respectively, and the optimal threshold was 3.49 pg/ml and AUC was 0.799 (95% CI: 0.688-0.909) (P<0.01). The PFS and OS were longer in the patients with IL-17≤3.49 pg/ml and longer in the patients without lymph node involvement and Ann Arbor I. Multivariate analysis showed that independent predictors of PFS and OS in patients with ENKTL were plasma IL-17 levels and age (P<0.05). ENKTL patients with different clinical characteristics have different levels of IL-17, the different level of IL-17 has different effects on prognosis of patients with ENKTL.

Outcomes in a RCTs of 12 weeks of theclinical efficacy of N-acetylcysteine (NAC) as an adjunctive treatment on depression and anxiety symptoms and its effects on high-sensitivity C-reactive protein (hs-CRP) levels. A wide array of measures were made. The 17-item version of the Hamilton Depression Rating Scale (HDRS17); the Hamilton Anxiety Rating Scale (HAM-A); Sheehan Disability Scale; Quality of Life; Clinical Global Impression (CGI); anthropometrics measures; and vital signs and biochemical laboratory. There were no significant differences among the groups regarding demographic, clinical features, use of medication, metabolic syndrome and comorbidities. From baseline to week 12, individuals receiving NAC, versus placebo, had a statistically significant reduction in depressive symptoms on HDRS 17 (p < 0.01) and anxiety symptoms on HAM-A (p = 0.04), but only for individuals with levels of hs-CRP > 3 mg/L at baseline. Individuals receiving NAC with baseline levels of hs-CRP > 3 mg/L, had more significant reduction in uric acid levels compared to individuals with baseline levels of hs-CRP ≤ 3 mg/L on week 12. Participants receiving placebogained significantly more weight during the 12 weeks for baseline levels of hs-CRP ≤ 3 mg/L and hs-CRP > 3 mg/L, and individuals receiving NAC in both groups did not have significant weight change during the 12 weeks. No individuals were withdrawn from the study because of adverse event. NAC group exhibited significantly greater reduction on hs-CRP levels than placebo group from baseline to week 12. clinicaltrials.gov Identifier; NCT02252341. Copyright © 2018 Elsevier B.V.

Cryptococcal meningitis (CM) is a leading cause of HIV-associated mortality. In clinical trials evaluating treatments for CM, biomarkers of early fungicidal activity (EFA) in cerebrospinal fluid (CSF) have been proposed as candidate surrogate endpoints for all- cause mortality (ACM). However, there has been no systematic evaluation of the group-level or trial-level evidence for EFA as a candidate surrogate endpoint for ACM. We conducted a systematic review of randomized trials in treatment of CM to evaluate available evidence for EFA measured as culture negativity at 2 weeks/10 weeks and slope of EFA as candidate surrogate endpoints for ACM. We performed sensitivity analysis on superiority trials and high quality trials as determined by Cochrane measures of trial bias. Twenty-seven trials including 2854 patients met inclusion criteria. Mean ACM was 15.8% at 2 weeks and 27.0% at 10 weeks with no overall significant difference between test and control groups. There was a statistically significant group-level correlation between average EFA and ACM at 10 weeks but not at 2 weeks. There was also no statistically significant group-level correlation between CFU culture negativity at 2weeks/10weeks or average EFA slope at 10 weeks. A statistically significant trial-level correlation was identified between EFA slope and ACM at 2 weeks, but is likely misleading, as there was no treatment effect on ACM. Mortality remains high in short time periods in CM clinical trials. Using published data and Institute of Medicine criteria, evidence for use of EFA as a surrogate endpoint for ACM is insufficient and could provide misleading results from clinical trials. ACM should be used as a primary endpoint evaluating treatments for cryptococcal meningitis.

Gitelman syndrome (GS), an inherited autosomal recessive salt-losing renal tubulopathy caused by mutations in SLC12A3 gene, has been associated with normal prostaglandin E2 (PGE2) levels since 1995 by a study involving 11 clinically diagnosed patients. However, it is difficult to explain why cyclooxygenase-2 (COX2) inhibitors, which pharmacologically reduce PGE2 synthesis, are helpful to patients with GS, and few studies performed in the last 20 years have measured PGE2 levels. The relationships between the clinical manifestations and PGE2 levels were never thoroughly analyzed. This study involved 39 GS patients diagnosed by SLC12A3 gene sequencing. Plasma and 24-h urine samples as well as the clinical data were collected at admission. PGE2 and PGEM levels were detected in plasma and urine samples by enzyme immunoassays. The in vivo function of the sodium-chloride co-transporter (NCC) in GS patients was evaluated using a modified thiazide test. The association among PGE2 levels, clinical manifestations and the function of NCC in GS patients were analyzed. Significantly higher levels of urinary and plasma PGEM were observed in GS patients than in the healthy volunteers. Higher urinary PGEM levels indicated more severe clinical manifestations and NCC dysfunction estimated by the increase of Cl- clearance. A higher PGEM level was found in male GS patients, who showed earlier onset age and more severe hypokalemia, hypochloremia and metabolic alkalosis than female GS patients. No relationship between renin angiotensin aldosterone system activation and PGEM level was observed. Higher urinary PGEM levels indicated more severe clinical manifestations and NCC dysfunction in GS patients. COX2 inhibition might be a potential therapeutic target in GS patients with elevated PGEM levels.

Previous studies have revealed the interactive effects of airborne pollen and particulate matter on the daily consultations for pollinosis, but it is uncertain which compositions are responsible. This study aimed to investigate the interactive effects of specific PM 2.5 compositions and airborne pollen on the daily number of clinic visits for pollinosis in Fukuoka. We obtained daily data on pollen concentrations, PM 2.5 compositions, PM 2.5 mass, gaseous pollutants (SO 2 , NO 2 , CO, and O 3 ), and weather variables monitored in Fukuoka between February and April, 2002-2012. In total, 73,995 clinic visits for pollinosis were made at 10 clinics in Fukuoka Prefecture during the study period. A time-stratified case-crossover design was applied to examine the interactive effects. The concentrations of PM 2.5 and its compositions were stratified into low (<15th percentile), moderate (15th-85th percentile), and high (>85th percentile) levels, and the association between airborne pollen and daily clinic visits for pollinosis was analyzed within each level. We found a significant interaction between specific PM 2.5 compositions and airborne pollen. Specifically, the odds ratio of daily clinic visits for pollinosis per interquartile increase in pollen concentration (39.8 grains/cm 2 ) at the average cumulative lag of 0 and 2 days during high levels of non-sea-salt Ca 2+ was 1.446 (95% CI: 1.323-1.581), compared to 1.075 (95% CI: 1.067-1.083) when only moderate levels were observed. This result remained significant when other air pollutants were incorporated into the model and was fairly persistent even when different percentile cut-off points were used. A similar interaction was found when we stratified the data according to non-sea-salt SO 4 2- levels. This finding differed from estimates made according to PM 2.5 and NO 3 - levels, which predicted that the effects of pollen were strongest in the lower levels. Associations between airborne pollen and daily clinic visits for pollinosis could be enhanced by high levels of specific PM 2.5 compositions, especially non-sea-salt Ca 2+ .

An external cavity laser (ECL)-based off-axis cavity-enhanced absorption spectroscopy was applied to noninvasive clinical diagnosis using expired breath ammonia analysis: (1) the correlation between breath ammonia levels and blood parameters related to chronic kidney disease (CKD) was investigated and (2) the relationship between breath ammonia levels and blood concentrations of valproic acid (VAP) was studied. The concentrations of breath ammonia in 15 healthy volunteers, 10 epilepsy patients (before and after taking VAP), and 27 patients with different stages of CKD were examined. The range of breath ammonia levels was 120 to 530 ppb for healthy subjects and 710 to 10,400 ppb for patients with CKD. There was a statistically significant positive correlation between breath ammonia concentrations and urea, blood urea nitrogen, creatinine, or estimated glomerular filtration rate in 27 patients. It was demonstrated that taking VAP gave rise to increasing breath ammonia levels. A statistically significant difference was found between the levels of exhaled ammonia (NH3) in healthy subjects and in patients with epilepsy before and after taking VAP. The results suggest that our breath ammonia measurement system has great potential as an easy, noninvasive, real-time, and continuous monitor of the clinical parameters related to epilepsy and CKD.

The purpose of this study was to characterize the effects of clinical and genetic variables on the pharmacokinetics and complications of tacrolimus during the first year after kidney transplantation. One hundred and thirty-two Korean kidney recipients who received tacrolimus were genotyped for ABCB1 (exons 12, 21, and 26) and CYP3A5 (intron 3). Tacrolimus trough levels, dose, or dose-adjusted trough levels and complications were compared among patients during the early stage (3, 7, 14, 30, and 90 days) and up to 1 year according to the genotypes. A donor source-adjusted linear mixed model with multilevel analysis adjusting for age, body weight, hematocrit, and serum creatinine showed that CYP3A5 genotype is associated with dose-adjusted level of tacrolimus (p < 0.001). The influence of ABCB1 polymorphisms on the pharmacokinetics or complications of tacrolimus was less certain in our study. The incidence of acute rejections was significantly higher in recipients of cadaveric donor kidney (p < 0.05). A generalized estimating equation model analysis showed that alopecia and hyperlipidemia were associated with dose-adjusted level of tacrolimus (p < 0.001). Genotype of CYP3A5 variants along with significant clinical covariates may be useful in individualizing tacrolimus therapy in kidney transplantation patients.

With aging, women's bodies undergo changes that can affect body image perception, yet little is known about body image in midlife. The purpose of this study was to examine associations between body image and depressive symptoms in Caucasian and African-American midlife women from the Study of Women's Health Across the Nation (SWAN) Chicago site. Body image was measured using the Stunkard Adult Female Figure Rating Scale, and a clinically significant level of depressive symptoms was defined as Center for Epidemiologic Studies Depression Scale (CES-D) score of ≥16 (N=405; N=63 (15.6%) with clinically significant levels of depressive symptoms). Differences between perceived actual, perceived ideal, and actual body size and responses to questions concerning weight satisfaction and attractiveness were examined using logistic regression for associations with a CES-D score of ≥16. Women with body image dissatisfaction (odds ratio (OR)=1.91; p=0.04) or who perceived themselves as "unattractive" (OR=7.74; p<0.01) had higher odds of CES-D of ≥16. We found no significant difference by race. Our results were not confounded by BMI. These results suggest that midlife women with poor body image may be more likely to have clinically significant levels of depressive symptoms. Larger prospective studies are needed to better understand this association.

The effect of a variety of preadmission variables, including the number of elective preadmission upper-level science courses, on academic achievement is not well established. To investigate the relationship between number of preadmission variables and overall student academic achievement in osteopathic medical school. Academic records of osteopathic medical students in the 2008 and 2009 graduating classes of Western University of Health Sciences College of Osteopathic Medicine of the Pacific in Pomona, California, were analyzed. Multivariate linear regression analyses were performed to identify predictors of academic achievement based on Medical College Admission Test (MCAT) subscores, undergraduate grade point average (GPA), GPA in medical school basic science (preclinical GPA) and clinical clerkship (clinical GPA), and scores on the Comprehensive Osteopathic Medical Licensing Examination-USA (COMLEX-USA) Level 1 and Level 2-Cognitive Evaluation (CE). Records of 358 osteopathic medical students were evaluated. Analysis of beta coefficients suggested that undergraduate science GPA was the most important predictor of overall student academic achievement (P<.01). Biological sciences MCAT subscore was a more modest but still statistically significant predictor of preclinical GPA and COMLEX-USA Level 1 score (P<.01). Physical sciences MCAT subscore was also a statistically significant predictor of preclinical GPA, and verbal reasoning MCAT subscore was a statistically significant predictor of COMLEX-USA Level 2-CE score (both P<.01). Women had statistically significantly higher preclinical GPA and COMLEX-USA Level 2-CE scores than men (P<.05). Differences in some outcome variables were also associated with racial-ethnic background and age. Number of preadmission elective upper-level science courses taken by students before matriculation was not significantly correlated with any academic achievement variable. Although undergraduate science GPA and MCAT biological sciences subscore were significant predictors of overall academic achievement for osteopathic medical students, the number of elective upper-level science courses taken preadmission had no predictive value.

It is suggested that CD30 and CD26 are surface molecules expressed on activated Th2 and Th1 cells, respectively. We examined plasma levels of soluble CD26 (sCD26) and sCD30 in patients with atopic dermatitis (AD) when their eruptions were aggravated and in non-atopic healthy controls, and then analysed the possible correlation between these values and the levels of several clinical markers. The plasma levels of both sCD30 and sCD26 were significantly higher in AD patients than in controls, both in exacerbation status and after conventional treatment. Multiple regression analyses showed that plasma sCD30 was a much better predictor of the levels of serum IgE, serum LDH and plasma sCD25, and the area and the score of AD eruption than sCD26, although elevated levels of both sCD30 and sCD26 are associated with these clinical predictors of AD. Importantly, sCD30 plasma levels decreased significantly in AD patients after conventional treatment, while no significant transition was noted in the concentration of sCD26. Moreover, a significant reduction of sCD30 levels was observed in the group of patients whose eruption score was reduced > 50%, whereas it was not in those < 50%. These findings provide evidence that the successful treatment of AD is associated with down-activation of Th2. PMID:10931130

The role of cytokines in relation to clinical manifestations, disease severity, and outcome of children with H1N1 virus infection remains thus far unclear. The aim of this study was to evaluate interleukin IL-1β and IL-6 plasma expressions and their association with clinical findings, disease severity, and outcome of children with H1N1 infection. We prospectively evaluated 15 children with H1N1 virus infection and 15 controls with lower respiratory tract infections (LRTI). Interleukin plasma levels were measured using immunoenzymatic assays. Significantly higher levels of IL-1β and IL-6 were detected in all patients with H1N1 virus infection compared to controls. It is noteworthy to mention that in H1N1 patients with more severe clinical manifestations of disease IL-1β and IL-6 expressions were significantly upregulated compared to H1N1 patients with mild clinical manifestations. In particular, IL-6 was significantly correlated with specific clinical findings, such as severity of respiratory compromise and fever. No correlation was found between interleukin expression and final outcome. In conclusion, H1N1 virus infection induces an early and significant upregulation of both interleukins IL1β and IL-6 plasma expressions. The upregulation of these cytokines is likely to play a proinflammatory role in H1N1 virus infection and may contribute to airway inflammation and bronchial hyperreactivity in these patients.

To investigate communication abilities and other influential factors on nursing students at the beginning of clinical practical session. A cluster sample of 312 nursing students from 22 nursing colleges or universities was recruited. Communication ability of these participants was evaluated by 4 questionnaires for demographic data, clinical communication behavior, treatment communication skills and interpersonal communication skills at the beginning of clinical practical session. The stability and accuracy of the questionnaires were established with an overall content validity index of 0.78, the Cronbach's Alpha index ranged from 0.872 to 0.951, and the letter index fluctuates from 0.85 to 0.89. Results demonstrated that 88.1% of the nursing students require extra training in clinical communication behavior, treatment communication skills, and interpersonal communication skills. The Pearson analysis revealed significantly positive correlations between communication abilities and the students' educational level, clinical training experience, living circumstances and number of siblings. Most nursing students need communication skill training. Multiple factors, including educational level, living circumstances, number of siblings, and training experience significantly affect nursing students' communication abilities. Our study suggested a need to widely establish a communication course or clinical communication training program to improve nursing students' communication skills. Copyright © 2012 Elsevier Ltd.

Background Sushi repeat-containing protein X-linked 2 (SRPX2) is overexpressed in a variety of different tumor tissues and correlated with poor prognosis in patients. Little research focuses on the role of SRPX2 expression in prostate cancer (PCa), and the clinicopathological significance of the protein expression in this tumor is relatively unknown. However, our previous transcriptome data from those cancer stem-like cells indicated the role of SRPX2 in PCa. Materials and methods In this study, RT-PCR and Western blotting were firstly used to examine the SRPX2 expression in three PCa cell lines including LNCaP, DU145, and PC3, and then SRPX2 protein expression was immunohistochemically investigated and statistically analyzed in a series of 106 paraffin-embedded PCa tissue specimens. Results Significantly lower levels of SRPX2 expression were verified in the LNCaP cells, compared with the expression in the aggressive DU145 and PC3 cells, in both mRNA and protein levels. Immunohistochemically, there were variable SRPX2 protein expressions in the clinical samples. Moreover, high levels of SRPX2 expression in the PCa tissues were significantly associated with Gleason score (P=0.008), lymph node metastasis (P=0.009), and distant metastasis (P=0.021). Furthermore, higher levels of SRPX2 expression in the PCa tissues were significantly associated with shorter overall survival (OS) (P<0.001). Conclusion Our results demonstrate that SRPX2 is highly expressed in aggressive PCa cells in vitro, and its protein expression in PCa is significantly associated with malignant clinical features and shorter OS, strongly indicating its prognostic value in prostate cancers.

Many studies report associations between human genetic factors and immunity to malaria but few have been reliably replicated. These studies are usually country-specific, use small sample sizes and are not directly comparable due to differences in methodologies. This study brings together samples and data collected from multiple sites across Africa and Asia to use standardized methods to look for consistent genetic effects on anti-malarial antibody levels. Sera, DNA samples and clinical data were collected from 13,299 individuals from ten sites in Senegal, Mali, Burkina Faso, Sudan, Kenya, Tanzania, and Sri Lanka using standardized methods. DNA was extracted and typed for 202 Single Nucleotide Polymorphisms with known associations to malaria or antibody production, and antibody levels to four clinical grade malarial antigens [AMA1, MSP1, MSP2, and (NANP)4] plus total IgE were measured by ELISA techniques. Regression models were used to investigate the associations of clinical and genetic factors with antibody levels. Malaria infection increased levels of antibodies to malaria antigens and, as expected, stable predictors of anti-malarial antibody levels included age, seasonality, location, and ethnicity. Correlations between antibodies to blood-stage antigens AMA1, MSP1 and MSP2 were higher between themselves than with antibodies to the (NANP)4 epitope of the pre-erythrocytic circumsporozoite protein, while there was little or no correlation with total IgE levels. Individuals with sickle cell trait had significantly lower antibody levels to all blood-stage antigens, and recessive homozygotes for CD36 (rs321198) had significantly lower anti-malarial antibody levels to MSP2. Although the most significant finding with a consistent effect across sites was for sickle cell trait, its effect is likely to be via reducing a microscopically positive parasitaemia rather than directly on antibody levels. However, this study does demonstrate a framework for the feasibility of combining data from sites with heterogeneous malaria transmission levels across Africa and Asia with which to explore genetic effects on anti-malarial immunity.

Objectives Childhood-onset systemic lupus erythematosus (cSLE) is a multisystemic autoimmune disease characterized by inflammatory organ damage by means of vasculitis. Pentraxin-3 (PTX3) is expressed locally at the sites of inflammatory processes, predominantly from endothelial cells. In adult studies, PTX3 has shown to be an indicator of active vasculitis both in large-vessel and small-vessel vasculitides, as well as in SLE. Moreover, in SLE it has found to be correlated with disease activity, and with some of the clinical manifestations and laboratory parameters. We aimed to ascertain if PTX3 might be a significant mediator in cSLE and if it might indicate active vasculitis during the course of the disease. Methods Serum PTX3 levels were measured in 76 patients with cSLE and 41 healthy subjects. We have investigated its relation with disease activity, damage, clinical features, laboratory parameters and medications. Results Serum levels of PTX3 were found to be increased in cSLE compared to healthy controls (mean ± SD; 10.6 ± 8.2 ng/mL vs 2.7 ± 1.3 ng/mL, p < 0.001). PTX3 concentrations were also in correlation with SLEDAI-2K ( r = 0.57, p < 0.001). When viewed from the clinical perspective, serum PTX3 levels were significantly higher only in patients with active vasculitis ( p < 0.001), Raynaud phenomenon ( p = 0.006) and mucocutaneous manifestations ( p < 0.001). However, an association between PTX3 and age, age at disease onset, disease duration, complement levels, PedSDI score (pediatric version of the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index), ESR, CRP, procalcitonin levels, anti-ds DNA antibody, anticardiolipin antibodies was not detected. Conclusions Patients with cSLE have increased levels of serum PTX3 compared to healthy controls. Thus, serum PTX-3 level might be a significant mediator in cSLE. Apart from these, the results support that PTX3 reflects active cutaneous vasculitis in cSLE and correlates with disease activity.

Despite high mortality rates, elder self-neglect is characterized by refusal of medical and social interventions. To date there have been no tested clinical interventions in elders who self-neglect. Previous research from the TEAM Institute has shown significantly low vitamin D levels in this population. This study aimed to determine the feasibility of a clinical intervention. Replacement of vitamin D was chosen because of its ease of administration and favorable safety profile. Methods: A randomized clinical trial using directly observed therapy of vitamin D was conducted using 50 elders, >65 years of age, with Adult Protective Services (APS) validated self-neglect. A staggered intervention with waiting controls was used to maximize statistical power. One-third (n=17) of the group was administered 50,000 IU vitamin D2 (ergocalciferol) monthly and the remainder (n=33) were administered 400 IU monthly. Serum 25-OH vitamin D was assessed at baseline and 5-months. Results: 69% agreed to participate in the study and of those n=40 (80%) remained at 5-months. At baseline, 12% (n=7) were deficient in vitamin D (<30nmol/L) and approximately 38% (n=22) had inadequate vitamin D levels (<50nmol/L). The baseline 25-OH vitamin D level was 59 nmol/L +25 (mean SD), and increased significantly to 72nmol/L +21 nmol/L at 5-months. Conclusion: These data are the first to provide evidence that clinical interventions are feasible in elders who self-neglect. The increase in vitamin D levels confirmed that the study personnel were able to successfully intervene community-dwelling elders with self-neglect. This study sets the precedent for future intervention and prevention studies

Because of the clinical significance of carotid atherosclerosis, the search for novel biomarkers has become a priority. The aim of the present study was to compare the protein secretion profile of the carotid atherosclerotic plaque (CAP, n = 12) and nonatherosclerotic mammary artery (MA, n = 10) secretomes. We used a nontargeted proteomic approach that incorporated tandem immunoaffinity depletion, iTRAQ labeling, and nanoflow liquid chromatography coupled to high-resolution mass spectrometry. In total, 162 proteins were quantified, of which 25 showed statistically significant differences in secretome levels between carotid atherosclerotic plaque and nondiseased mammary artery. We found increased levels of neutrophil defensin 1, apolipoprotein E, clusterin, and zinc-alpha-2-glycoprotein in CAP secretomes. Results were validated by ELISA assays. Also, differentially secreted proteins are involved in pathways such as focal adhesion and leukocyte transendothelial migration. In conclusion, this study provides a subset of identified proteins that are differently expressed in secretomes of clinical significance.

Diminished levels of mindfulness (awareness and acceptance/nonjudgment) and difficulties in emotion regulation have both been proposed to play a role in symptoms of generalized anxiety disorder (GAD); the current studies investigated these relationships in a nonclinical and a clinical sample. In the first study, among a sample of 395 individuals at an urban commuter campus, we found that self reports of both emotion regulation difficulties and aspects of mindfulness accounted for unique variance in GAD symptom severity, above and beyond shared variance with depressive and anxious symptoms, as well as shared variance with one another. In the second study, we found that individuals diagnosed with clinically significant GAD (n = 16) reported significantly lower levels of mindfulness and significantly higher levels of difficulties in emotion regulation than individuals in a non-anxious control group (n = 16). Results are discussed in terms of directions for future research and potential implications for treatment development. PMID:19433145

Myalgic Encephalopathy/Chronic Fatigue Syndrome (ME/CFS) is a disease of unknown etiology. We have previously suggested clinical benefit from B-cell depletion using the monoclonal anti-CD20 antibody rituximab in a randomized and placebo-controlled study. Prolonged responses were then demonstrated in an open-label phase-II study with maintenance rituximab treatment. Using blood samples from patients in the previous two clinical trials, we investigated quantitative changes in T-lymphocyte subsets, in immunoglobulins, and in serum levels of two B-cell regulating cytokines during follow-up. B-lymphocyte activating factor of the tumor necrosis family (BAFF) in baseline serum samples was elevated in 70 ME/CFS patients as compared to 56 healthy controls (p = 0.011). There were no significant differences in baseline serum BAFF levels between patients with mild, moderate, or severe ME/CFS, or between responders and non-responders to rituximab. A proliferation-inducing ligand (APRIL) serum levels were not significantly different in ME/CFS patients compared to healthy controls at baseline, and no changes in serum levels were seen during follow-up. Immunophenotyping of peripheral blood T-lymphocyte subsets and T-cell activation markers at multiple time points during follow-up showed no significant differences over time, between rituximab and placebo groups, or between responders and non-responders to rituximab. Baseline serum IgG levels were significantly lower in patients with subsequent response after rituximab therapy compared to non-responders (p = 0.03). In the maintenance study, slight but significant reductions in mean serum immunoglobulin levels were observed at 24 months compared to baseline; IgG 10.6-9.5 g/L, IgA 1.8-1.5 g/L, and IgM 0.97-0.70 g/L. Although no functional assays were performed, the lack of significant associations of T- and NK-cell subset numbers with B-cell depletion, as well as the lack of associations to clinical responses, suggest that B-cell regulatory effects on T-cell or NK-cell subsets are not the main mechanisms for the observed improvements in ME/CFS symptoms observed in the two previous trials. The modest increase in serum BAFF levels at baseline may indicate an activated B-lymphocyte system in a subgroup of ME/CFS patients.

The purpose of this study was to evaluate the outcome of DM2 patients with nephropathy when they are under surveillance of a joined clinic run by endocrinologists & nephrologists. A cohort of 106 patients with DM2, 42-83 years of age, and eGFR < 60 ml/min/m 2 were included. Age, sex, duration of diabetes, duration of attending our clinic, smoking habits, BMI, data regarding ischemic heart disease and induction of hemodialysis, urine albumin excretion (UAE) levels, eGFR (MDRD equation) and values of various biochemical parameters were recorded too. Follow-up period ranged from one to 25 years. Paired samples t-test and non-parametrical Kruskal-Wallis test were used for the analyses of the data. Fifty percent of patients had no further progression, 25.9% improvement, while 24.1% had worsening of the UAE levels. During the follow-up in the joined clinic, there was a smaller than the expected from the medical literature decrease in median eGFR, i.e. 2,3 ml/min/m 2 and a statistically significant improvement in glycosylated hemoglobin levels from 8.0% to 7.4% (p = 0.016). Time in years of follow-up in the joined clinic of our hospital appeared to be the most significant factor in the improvement or stabilization against deterioration of the UAE levels (p = 0.018). Close follow-up of DM2 patients with eGFR < 60 ml/min/m 2 has resulted in a minor annual eGFR decrease. Monitoring of these patients in a specialized diabetic nephropathy clinic is beneficial for this group of patients for delaying the occurrence of end-stage renal disease.

Glioblastoma multiforme is the most common primary brain tumor and is highly lethal. This study aims to figure out signatures for predicting the survival time of patients with glioblastoma multiforme. Clinical information, messenger RNA expression, microRNA expression, and single-nucleotide polymorphism array data of patients with glioblastoma multiforme were retrieved from The Cancer Genome Atlas. Patients were separated into two groups by using 1 year as a cutoff, and a logistic regression model was used to figure out any variables that can predict whether the patient was able to live longer than 1 year. Furthermore, Cox's model was used to find out features that were correlated with the survival time. Finally, a Cox model integrated the significant clinical variables, messenger RNA expression, microRNA expression, and single-nucleotide polymorphism was built. Although the classification method failed, signatures of clinical features, messenger RNA expression levels, and microRNA expression levels were figured out by using Cox's model. However, no single-nucleotide polymorphisms related to prognosis were found. The selected clinical features were age at initial diagnosis, Karnofsky score, and race, all of which had been suggested to correlate with survival time. Both of the two significant microRNAs, microRNA-221 and microRNA-222, were targeted to p27 Kip1 protein, which implied the important role of p27 Kip1 on the prognosis of glioblastoma multiforme patients. Our results suggested that survival modeling was more suitable than classification to figure out prognostic biomarkers for patients with glioblastoma multiforme. An integrated model containing clinical features, messenger RNA levels, and microRNA expression levels was built, which has the potential to be used in clinics and thus to improve the survival status of glioblastoma multiforme patients.

As the older population increases so does the number of older psychiatric patients. Elderly psychiatric patients manifest certain specific and unique characteristics. Different subtypes of depressive syndromes exist in late-life depression, and many of these are associated with cognitive impairment. A total of 109 depressive patients and 30 normal subjects matched by age and educational level were evaluated using a neuropsychiatric interview and an extensive neuropsychological battery. Depressive patients were classified into four different groups by SCAN 2.1 (schedules for clinical assessment in Neuropsychiatry): major depression disorder (n: 34), dysthymia disorder (n: 29), subsyndromal depression (n: 28), and depression due to mild dementia of Alzheimer's type (n: 18). We found significant associations (p<.05) between depressive status and demographic or clinical factors that include marital status (OR: 3.4, CI: 1.2-9.6), level of daily activity (OR: 5.3, CI: 2-14), heart disease (OR: 12.5, CI: 1.6-96.3), and high blood cholesterol levels (p:.032). Neuropsychological differences were observed among the four depressive groups and also between depressive patients and controls. Significant differences were observed in daily life activities and caregivers' burden between depressive patients and normal subjects. Geriatric depression is associated with heart disease, high cholesterol blood levels, marital status, and daily inactivity. Different subtypes of geriatric depression have particular clinical features, such as cognitive profiles, daily life activities, and caregivers' burden, that can help to differentiate among them. The cohort referred to a memory clinic with memory complaints is a biased sample, and the results cannot be generalized to other non-memory symptomatic cohorts. Copyright © 2011 Elsevier B.V.

In sixteen autistic children high values of IgG and a high level of lymphocyte stimulation with PHA were observed. Principal component analysis showed: 1) a significant correlation between basic lymphocyte mitogenic activity and the clinical symptoms opposition and hyperactivity, 2) a significant correlation between high Ig levels, high PHA stimulation responses and the main autistic symptoms (withdrawal, inaffectivity, hypoactivity, mannerism, stereotypy and negatively echolalia), 3) a significant correlation with serotonin uptake by platelets and high immunological responses. Such correlations are strongly in favor of an immunologic component in autistic disease.

To provide a population-based clinical audit of children and young people with diabetes, reporting outcomes, including glycaemic control, for named individual units. Clinical audit data on care processes and glycated haemoglobin (HbA(1c)) were collected for 1742 children and young people treated in 16 paediatric units in Yorkshire, from January 2005 to March 2006. The Yorkshire Register of Diabetes in Children and Young People provided information technology support and validation that enhanced data quality. Multi-level linear regression modelling investigated factors affecting glycaemic control. An HbA(1c) measure was recorded for 91.6% of patients. The National Institute for Clinical Excellence-recommended target level for HbA(1c) of < 7.5% was achieved for 14.7% of patients. HbA(1c) was positively associated with duration of diabetes and later age at diagnosis. Patients living in deprived areas had significantly poorer control compared with those from affluent areas. Significant between-unit variation in HbA(1c) was not reflected by any association with unit size. Our population-based clinical audit of children with diabetes is the product of an effective collaboration between those who deliver care and health services researchers. High levels of recording the key care process measuring diabetes control, compared with national figures, suggests collaboration has translated into improved services. The interesting association between poor diabetes control and higher deprivation is noteworthy and requires further investigation. Future audits require recording of clinical management and clinic structures, in addition to resources to record, assemble and analyse data.

To identify (1) the predominant level of evidence of the clinical studies regarding the hip pathology, risk factors, treatment, and clinical outcomes in artistic athletes (dancers, figure skaters, and gymnasts) (2) the most commonly reported hip pathology, risk factors, treatments, and clinical outcomes in dancers, figure skaters, and gymnasts. To conduct this systematic review PubMed, EMBASE, and Scopus databases were searched for relevant studies and pertinent data were collected from the eligible articles. Included were studies which reported hip injuries in artistic athletes, the risk factors, treatment, and/or the clinical outcomes. We excluded case reports or irrelevant studies. No meta-analysis was performed because of study heterogeneity. The methodical index for nonrandomized studies (MINORS) criteria were used for quality control. Thirty-eight studies were included in the analysis. The mean MINORS score was 13.6 ± 4.6 points indicating fair quality of evidence of the included articles. The predominant level of evidence was level IV. Chondrolabral pathology and muscle injuries were the most commonly reported pathologies. We found only 2 risk factor analysis studies; however, many studies reported risk correlation between artistic sports or imaging findings and hip pathology. Treatment strategies were reported in only 7 studies, clinical outcomes are significantly underreported. Chondrolabral pathology was the most commonly reported hip pathology in artistic athletes, however, prospective cohort studies are necessary to really understand these injuries and their associated risk factors. The lack of clinical outcomes is significant and future data collection is required to assess the effectiveness of the various treatments.

We chose to examine the impact of socioeconomic factors on accrual to National Cancer Institute (NCI)-sponsored cancer treatment trials. We estimated the geographic and demographic cancer burden in the United States and then identified 24,332 patients accrued to NCI-sponsored cancer treatment trials during a 12-month period. Next, we examined accrual by age, sex, geographic residence, health insurance status, health maintenance organization market penetration, several proxy measures of socioeconomic status, the availability of an oncologist, and the presence of a hospital with an approved multidisciplinary cancer program. Pediatric patients were accrued to clinical trials at high levels, whereas after adolescence, only a small percentage of cancer patients were enrolled onto clinical trials. There were few differences by sex. Black males as well as Asian-American and Hispanic adults were accrued to clinical trials at lower rates than white cancer patients of the same age. Overall, the highest observed accrual was in suburban counties. Compared with the United States population, patients enrolled onto clinical trials were significantly less likely to be uninsured and more like to have Medicare health insurance. Geographic areas with higher socioeconomic levels had higher levels of clinical trial accruals. The number of oncologists and the presence of approved cancer programs both were significantly associated with increased accrual to clinical trials. We must work to increase the number of adults who enroll onto trials, especially among the elderly. Ongoing partnership with professional societies may be an effective approach to strengthen accrual to clinical trials.

The study was designed to investigate the antimanic profile of carbamazepine as a first-line drug in affective or schizoaffective disorders, to correlate the clinical efficacy with the plasma level of carbamazepine and its 10,11-epoxide metabolite, and to test the potential value of monitoring the salivary level. It was administered alone for 3 weeks to 21 acute manic inpatients. During the first week, the dosage was rapidly increased to 800 mg/day in order to produce steady-state plasma levels of carbamazepine on Day 7. The individual dose was then adjusted to maintain the therapeutic range of 8-12 mg/l. Plasma and saliva levels of the drug and its metabolite, as well as clinical status were assessed weekly. Overall, there was 62% globally improved patients and 77% in affective disorders. The improvement of manic symptoms was significantly lower in schizoaffective than in affective disorders, whereas the dropout rate and the need for antipsychotic medication was higher in the former group. The antimanic response was significantly correlated with the plasma levels both of carbamazepine and its epoxide metabolite, with a time-lag consistent with a delayed drug effect. Drug and metabolite concentrations in saliva were close to their plasma free fraction and were strongly correlated with their plasma levels, suggesting the potential value of salivary drug monitoring.

Female undergraduates (n = 185) living in the Pacific Northwest during fall, winter, and spring academic terms completed the Center for Epidemiologic Studies Depression (CES-D) scale weekly for four weeks (W1–W5). We measured serum levels of vitamin D3 and C (ascorbate; as a control variable) in blood samples collected at W1 and W5. Vitamin D insufficiency (<30ng/mL) was common at W1 (42%) and W5 (46%), and rates of clinically significant depressive symptoms (CES-D ≥ 16) were 35–42% at W1–W5. Lower W1 vitamin D3 predicted clinically significant depressive symptoms across W1–W5 (β = −.20, p < .05), controlling for season, BMI, race/ethnicity, diet, exercise, and time outside. There was some evidence that lower levels of depressive symptoms in Fall participants (vs. Winter and Spring) were explained by their higher levels of vitamin D3. W1 depressive symptoms did not predict change in vitamin D3 levels from W1 to W5. Findings are consistent with a temporal association between low levels of vitamin D and clinically meaningful depressive symptoms. The preventive value of supplementation should be tested further.

Introduction  Allergic rhinitis (AR) affects up to 40% of the population and results in nasal itching, congestion, sneezing, and clear rhinorrhea. Objectives  This study aimed to evaluate the changes in the clinical symptoms and in the level of serum interleukin (IL)-33 before and after pollen immunotherapy (IT) in patients with AR. Methods  The total symptom score and the levels of total immunoglobulin E (IgE) and IL-33 were determined in the serum of 10 non-allergic healthy controls and 45 patients with AR who were equally divided into 3 groups: GI (patients did not receive IT), GII (patients had received IT for 6 months) and GIII (patients had received IT for 2 years). Results  There was a significantly higher concentration of IgE and IL-33 in the serum of patients with AR than in that of non-allergic patients. Furthermore, serum level of IL-33 decreased significantly after pollen IT. But, there was no significant reduction in the serum level of IL-33 between GII and GIII patients. Conclusion  Our results show a clinical improvement associated with a decrease in serum level of IL-33 after pollen IT. PMID:29619104

The purpose of this investigation was to analyze by cross-sectional design the association between GCF IL-6 level, serum E2 level and common clinical measurements of periodontitis in Uyghur postmenopausal women. 79 subjects within 5 years after menopause were enrolled in the study. 30 GCF samples were harvested from healthy sites, 49 GCF samples from chronic periodontitis sites. Clinical measurements of each tooth were recorded after obtaining GCF samples. GCF IL-6 and serum E2 levels were measured by radioimmunoassay (RIA). The mean concentration of GCF IL-6 from healthy sites was (1088.10+/-102.33)pg/ml.The mean concentration of IL-6 from chronic periodontitis sites was significantly higher than that of healthy sites (P<0.005). Positive correlation was found between GCF IL-6 level and clinical measurements (GI, PPD and CAL) (r=0.564, P<0.005; r=0.335, P<0.05; r=0.324, P<0.05). Clinical measurements and GCF IL-6 levels of chronic periodontitis subjects were not different between E2-deficient and E2-sufficient subjects. These findings suggest that there is lower IL-6 level in GCF from healthy sites; the increasing production of IL-6 may be associated with the initiation and progress of periodontitis. IL-6 may be a valuable indicator of the severity of periodontitis; E2 level is not associated with clinical measurements and GCF IL-6 level of chronic periodontitis of Uyghuy woman in early menopause.

Aims. To evaluate the efficacy and safety of mulberry twig alkaloid (SZ-A) tablet compared with acarbose in patients with type 2 diabetes. Methods. This clinical trial enrolled 38 patients who were randomized into two groups (SZ-A: 23; acarbose: 15) and were treated for 24 weeks. Patients and clinical trial staffs were masked to treatment assignment throughout the study. The primary outcome measures were glycated hemoglobin (HbA1c) and 1-hour and 2-hour postprandial and fasting plasma glucose levels from baseline to the end of treatment. Analysis included all patients who completed this study. Results. By the end of this study, HbA1c level in SZ-A group was decreased from baseline significantly (P < 0.001). No significant difference was found when compared with acarbose group (P = 0.652). Similarly, 1-hour and 2-hour postprandial plasma glucose levels in SZ-A group were decreased from baseline statistically (P < 0.05), without any significant differences compared with acarbose group (P = 0.748 and 0.558, resp.). The fasting plasma glucose levels were not significantly changed in both groups. One of 23 patients in SZ-A group (4.76%) and 5 of 15 patients in acarbose group (33.33%) suffered from gastrointestinal adverse events. Conclusions. Compared with acarbose, SZ-A tablet was effective and safe in glycemic control in patients with type 2 diabetes. PMID:27547230

Preeclampsia (PE) complicates 3–8% of all pregnancies and manifests clinically as hypertension and proteinuria in the second half of gestation. The pathogenesis of PE is not fully understood but recent studies have described the involvement of cell-free fetal hemoglobin (HbF). Hypothesizing that PE is associated with prolonged hemolysis we have studied the response of the cell-free Hb- and heme defense network. Thus, we have investigated the levels of cell-free HbF (both free, denoted HbF, and in complex with Hp, denoted Hp-HbF) as well as the major human endogenous Hb- and heme-scavenging systems: haptoglobin (Hp), hemopexin (Hpx), α1-microglobulin (A1M) and CD163 in plasma of PE women (n = 98) and women with normal pregnancies (n = 47) at term. A significant increase of the mean plasma HbF concentration was observed in women with PE. Plasma levels of Hp and Hpx were statistically significantly reduced, whereas the level of the extravascular heme- and radical scavenger A1M was significantly increased in plasma of women with PE. The Hpx levels significantly correlated with maternal blood pressure. Furthermore, HbF and the related scavenger proteins displayed a potential to be used as clinical biomarkers for more precise diagnosis of PE and are candidates as predictors of identifying pregnancies with increased risk of obstetrical complications. The results support that PE pathophysiology is associated with increased HbF-concentrations and an activation of the physiological Hb-heme defense systems. PMID:26368565

To summarize the association of vitamins (B6, B12, C, D, and E) and abdominal aortic aneurysm (AAA), we reviewed clinical studies with a comprehensive literature research and meta-analytic estimates. To identify all clinical studies evaluating the association of vitamins B6/B12/C/D/E and AAA, databases including MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched through April 2015, using Web-based search engines (PubMed and OVID). For each case-control study, data regarding vitamin levels in both the AAA and control groups were used to generate standardized mean differences (SMDs) and 95% confidence intervals (CIs). Pooled analyses of the 4 case-control studies demonstrated significantly lower circulating vitamin B6 levels (SMD, -0.33; 95% CI, -0.55 to -0.11; P=0.003) but non-significantly lower vitamin B12 levels (SMD, -0.42; 95% CI, -1.09 to 0.25; P=0.22) in patients with AAA than subjects without AAA. Pooled analyses of the 2 case-control studies demonstrated significantly lower levels of circulating vitamins C (SMD, -0.71; 95% CI, -1.23 to -0.19; P=0.007) and E (SMD, -1.76; 95% CI, -2.93 to 0.60; P=0.003) in patients with AAA than subjects without AAA. Another pooled analysis of the 3 case-control studies demonstrated significantly lower circulating vitamin D (25-hydroxyvitamin D) levels (SMD, -0.25; 95% CI, -0.50 to -0.01; P=0.04) in patients with AAA than subjects without AAA. In a double-blind controlled trial, 4.0-year treatment with a high-dose folic acid and vitamin B6/B12 multivitamin in kidney transplant recipients did not reduce a rate of AAA repair despite significant reduction in homocysteine level. In another randomized, double-blind, placebo-controlled trial, 5.8-year supplementation with α-tocopherol (vitamin E) had no preventive effect on large AAA among male smokers. In clinical setting, although low circulating vitamins B6/C/D/E (not B12) levels are associated with AAA presence, vitamins B6/B12/E supplementation may not reduce AAA incidence.

Background The aim of the present study was to evaluate the effects of glucosamine-chondroitin sulphate combination on internal derangements of temporomandibular joint in clinical and biochemical manners. Material and Methods This randomized clinical study included 31 cases reporting joint tenderness, in which disc displacement was detected on MR imaging. In all patients, synovial fluid sampling was performed under local anesthesia. In the study group, the patients were prescribed a combination of 1500 mg glucosamine and 1200 mg chondroitin sulphate, while patients in the control group were only prescribed 50 mg tramadol HCl (twice daily) for pain control. After 8 weeks, synovial fluid sampling was repeated in the same manner. The levels of pain, maximum mouth opening (MMO), synovial fluid IL-1ß, IL-6, TNF-α and PGE2 measured before and after pharmacological intervention were compared. Results The reduction in pain levels was significant in both groups. There was no significant difference between two groups in terms of pain reduction. The improvement in MMO was significant in the study group but it was not in the control group. The MMO improvement was significantly higher in the study group compared to the control group. In the study group, significant decrease was observed in PGE2 level, while the decreases in IL-1β, IL-6 and TNF-α levels were not significant. In the control group, no significant decrease was observed in any of the inflammatory cytokines after 8 weeks, moreover IL-1ß and IL-6 levels were increased. Alterations of IL-1ß and IL-6 levels were significant in study group while TNF-α and PGE2 levels were not, compared to control group. Conclusions In conclusion, these results might suggest that glucosamine-chondroitin combination significantly increases the MMO and decreases the synovial fluid IL1β and IL6 levels in internal derangements of TMJ compared to tramadol. The modifications of synovial fluid TNF-α and PGE2 levels do not reach statistical significance. This combination also provides efficient pain relief in similar level with tramadol, a narcotic analgesic. Key words: Chondroitin sulphate, glucosamine, internal derangement, TMJ, tramadol.

To investigate the relationship between serum procalcitonin (PCT) levels and prognosis in children with bacterial meningitis. Eighty-two child patients were included in this prospective study. The diagnosis of meningitis was based on clinical features and cerebrospinal fluid findings. PCT levels were measured with a specific immunoluminometric assay. (a) Patients with bacterial meningitis had significantly higher serum PCT than those with viral meningitis. (b) The PCT levels of patients with severe sepsis or septic shock were significantly higher than those who had no or mild sepsis. (c) PCT levels decreased significantly in patients who had good curative effect, whereas PCT levels did not changed in patients who had no curative effect. (d) The PCT levels were significantly higher in those who died than those who survived. Serum PCT is related to the severity of disease in children with bacterial meningitis. A fall in PCT after treatment may have favorable prognostic significance. © The Author(s) 2015.

Dentistry is a profession demanding physical and mental efforts as well as people contact, which can result in burnout. The level of burnout among 307 clinical dental students in 2 Jordanian universities was evaluated using the Maslach Burnout Inventory survey. Scores for the inventory's 3 subscales were calculated and the mean values for the students' groups were computed separately. Dental students in both universities suffered high levels of emotional exhaustion and depersonalization. The dental students at the University of Jordan demonstrated a significantly higher level of emotional exhaustion than their counterparts at the Jordan University of Science and Technology.

Purpose Retinopathy of prematurity (ROP) is a vision-threatening disease associated with abnormal retinal vascular development. Proteins from the insulin-like growth factor pathway are related to ROP. However, there is a paucity of research on the role of other proteins in ROP. The aim of this study was to identify plasma proteins related to clinically significant ROP. Methods We measured 1121 plasma proteins in the early neonatal period in infants at risk for ROP using an aptamer-based proteomic technology. The primary aim of the study was to compare plasma protein concentrations in infants who did (n = 12) and did not (n = 23) subsequently develop clinically significant ROP using logistic regression. As a secondary aim, we examined patterns in the proteins across categories of clinically significant, low-grade, and no ROP groups. Results Lower levels of 16 proteins were associated with an increased risk of clinically significant ROP. In this group, superoxide dismutase (Mn), mitochondrial (MnSOD), and chordin-like protein 1 (CRDL1) were highly ranked. Other proteins in this group included: C-C motif chemokine 14 (HCC-1), prolactin, insulin-like growth factor-binding protein 7 (IGFBP-7), and eotaxin. Higher levels of 12 proteins were associated with a higher risk for ROP. Fibroblast growth factor 19 (FGF-19) was the top-ranked protein target followed by hepatocyte growth factor-like protein (MSP), luteinizing hormone (LH), cystatin M, plasminogen, and proprotein convertase subtilisin/kexin type 9 (PCSK9). We also noted different patterns in the trend of concentrations of proteins across the clinically significant, low-grade, and no ROP groups. Conclusions We discovered plasma proteins with novel associations with clinically significant ROP (MnSOD, CRDL1, PCSK9), proteins with links to established ROP signaling pathways (IGFBP-7), and proteins such as MnSOD that may be a target for future therapeutic interventions.

The clinical significance of corrosion of cemented femoral stems is unclear. The purpose of this retrieval study was to: (1) report on corrosion at the stem-cement interface and (2) correlate these findings with clinical data. We analysed cemented stems (n = 36) composed of cobalt-chromium (CoCr) and stainless steel (SS) in a series of revised metal-on-metal hips. We performed detailed inspection of each stem to assess the severity of corrosion at the stem-cement interface using a scale of 1 (low) to 5 (severe). We assessed the severity of corrosion at each stem trunnion and measured wear rates at the head taper and bearing surfaces. We used non-parametric tests to determine the significance of differences between the CoCr and SS stems in relation to: (1) pre-revision whole blood Co and Cr metal ion levels, (2) trunnion corrosion, (3) bearing surface wear and (4) taper material loss. The corrosion scores of CoCr stems were significantly greater than SS stems (p < 0.01). Virtually all stem trunnions in both alloy groups had minimal evidence of corrosion. The median pre-revision Co levels of implants with CoCr stems were significantly greater than the SS stems (p < 0.01). There was no significant difference in relation to pre-revision Cr levels (p = 0.521). There was no significant difference between the two stem types in relation to bearing wear (p = 0.926) or taper wear (p = 0.148). Severe corrosion of cemented femoral stems is a common finding at our retrieval centre; surgeons should consider corrosion of CoCr stems as a potential source of metal ions when revising a hip.

Objective The purpose of this study was to examine the relationships among depressive symptoms, stress and severity of binge eating symptoms in a community sample of African American and Hispanic or Latina women. Method Women (African American n=127, Hispanic or Latina n=44) completed measures of body composition, stress, depression, and binge eating. Results Scores on a depressive symptom scale indicated that 24.0% of participants exhibited clinically significant levels of depressive symptoms. Mean binge eating scores were below the threshold for clinically diagnosed binge eating (12.99±7.90). Mean stressful event scores were 25.86±14.26 and the average stress impact score was 78.36±55.43. Linear regression models found that body composition, stress impact score, and being classified as having clinically significant levels of depression, were associated with severity of binge eating symptoms. Conclusion Higher levels of percent body fat, a CES-D score ≥16 and higher WSI-Impact scores were associated with greater severity of binge eating symptoms. PMID:23760851

Serum, cerebrospinal fluid (CSF), and cryopreserved lymphocytes from subjects in the Rush Alzheimer's Disease Center Religious Orders Study were analyzed for associations between cytomegalovirus (CMV) infection and clinical and pathological markers of Alzheimer disease. CMV antibody levels were associated with neurofibrillary tangles (NFTs). CSF interferon γ was only detected in seropositive subjects and was significantly associated with NFTs. The percentage of senescent T cells (CD4+ or CD8+CD28-CD57+) was significantly higher for CMV-seropositive as compared to CMV-seronegative subjects and was marginally associated with the pathologic diagnosis of Alzheimer disease (CD4+) or amyloid-β (CD8+). Immunocytochemical analysis showed induction of amyloid-β in human foreskin fibroblasts (HFFs) infected with each of 3 clinical CMV strains. In the same subjects, there was no association of herpes simplex virus type 1 (HSV-1) antibody levels with CMV antibody levels or clinical or pathological markers of Alzheimer disease. HSV-1 infection of HFFs did not induce amyloid-β. These data support an association between CMV and the development of Alzheimer disease.

Cognitive impairment was frequently reported in uremic patients with dialysis, but improvements of cognition after parathyroidectomy for symptomatic secondary hyperparathyroidism have never been reported before. Thirty-nine patients, who were successfully operated on with total parathyroidectomy plus autotransplantation were enrolled. Twenty-three dialysis patients, age >50 years, who had a serum level of intact parathyroid hormone (iPTH) greater than 650 pg/ml, and who did not undergo parathyroidectomy were selected as the control group. The mini-mental state examination (MMSE) and the clinical dementia rating (CDR) test were administered to all patients. Before the operation, educational level, symptoms of bone pain, skin itching, general weakness and insomnia were recorded and serum levels of calcium, phosphorus, alkaline phosphatase (Alk-ptase), iPTH, aluminum, and hemoglobin were measured in the study and control groups. At 12-week postoperatively, serum levels of calcium, phosphorus, Alk-ptase, iPTH, and aluminum were measured again and at 16-week postoperatively, the MMSE and the CDR test were administered again. In the control group, both MMSE and CDR test were administered again after the period or 16-week. Serum calcium level was only significant difference (p = 0.002), whereas clinical symptoms, gender, etiologies of secondary hyperparathyroidism, duration of dialysis, educational level, age, and serum levels of phosphorus, Alk-ptase, iPTH, aluminum, and hemoglobin were not significantly different between the two groups. The educational level was the only factor affecting MMSE scores (p = 0.003). In the study group, at 12-week postoperatively, symptoms improved significantly, serum levels of calcium, phosphorus, Alk-ptase, iPTH, and aluminum decreased significantly, and at 16-week postoperatively, MMSE scores increased from 25 +/- 5 (mean +/- SD) to 26 +/- 5 (p < 0.001) and CDR scales decreased significantly (p < 0.001). Neither MMSE scores nor CDR scales of the control group changed significantly after the 16-week period. Parathyroidectomy for symptomatic secondary hyperparathyroidism can improve cognition.

Transient hypocalcaemia is a frequent complication after total knee arthroplasty (TKA). In this study, we investigated the factors associated with the development of hypocalcaemia after TKA in order to explore its clinical significance and treatment. A retrospective analysis of the change of serum calcium levels for 40 patients after TKA was performed. We investigated the patients prospectively for age, gender, and amount of bleeding at operation. At 24 hours following the operation, serum calcium of the patients was evaluated and a t-test was performed to analyze the categorical variables. Pearson's correlation analysis was used to determine the risk of hypocalcaemia in univariate analysis. After TKA, the serum calcium level was significantly lower than that before the operation (p<0.01); the incidence of postoperative hypocalcaemia was 77.5%, the decline was positively correlated with intraoperative blood loss (Pearson's r=0.405, p=0.01). Hypocalcaemia occurs frequently after TKA, however, clinical symptoms associated with hypocalcaemia are rare. The calcium ion is an important electrolyte, neurotransmitter and blood coagulation factor. It is suggested that we should routinely monitor calcium ion levels during the perioperative period and deal with hypocalcaemia in a timely fashion.

The aim of this study was to investigate effects of Clinical Pilates Exercises on bone mineral density (BMD), physical performance and quality of life (QOL) in postmenopausal osteoporosis. Forty-one women were recruited to the study. The subjects were divided into two groups, as the Pilates group and the control group. Subjects were evaluated for BMD at the lumbar region. Physical performance level was measured. Pain intensity level was scored with Visual Analogue Scale. QUALEFFO-41 was used for assessing QOL. BMD values increased in the Pilates group (p < 0.05), while BMD decreased in the control group (p< 0.05). Physical performance test results showed significant increases in the Pilates group (p< 0.05) whereas there was no changes in the control group (p> 0.05). Pain intensity level in the Pilates group was significantly decreased after the exercise (p< 0.05), while it was unchanged in the control group. There were significant increases in all parameters of QOL in the Pilates group. Conversely, some parameters of QOL showed decreases in the control group (p< 0.05). Pilates Exercises is effective to increase BMD; QOL and walking distance and also beneficial to relieve pain. Physiotherapist can use Pilates Exercises for the subjects with osteoporosis in the clinics.

Serum sialic acid levels were measured in 16 patients with sympathetic ophthalmitis, 36 with neglected traumatic uveitis following penetrating injury and 40 healthy subjects. There was no significant alteration of its level in patients with traumatic uveitis. However, its level was significantly elevated in patients with sympathetic ophthalmitis. It was high even in the early stage of the disease. It decreased significantly at the remission stage. It is proposed that measurement of sialic acid level in serum can be used as a diagnostic aid when the diagnosis of sympathetic ophthalmitis remains doubtful on clinical grounds. The extent of rise in its level may be considered a good parameter of the degree of severity of sympathetic ophthalmitis. It may also act as a useful tool to evaluate the drug efficacy in this disease.

Objectives: Unhelpful beliefs about sleep have been linked to insomnia, and increasing one's cognitive flexibility about sleep has been linked to post-treatment sleep improvement. This study evaluated if levels of such beliefs differ across insomnia groups, and whether there are particular beliefs that differ for specific insomnia subtypes. Methods: Participants (N = 1384) were people with insomnia and good sleepers ranging from 18 to 89 years old (M = 42.6, SD = 19.4). Data from previous studies at five insomnia clinical sites were pooled to examine responses on the Dysfunctional Beliefs and Attitudes about Sleep Scale (DBAS-16) across differing insomnia groups. Results: Group analyses revealed that those from community-based insomnia clinics and those who are hypnotic-dependent generally had the highest levels of unhelpful sleep-related beliefs. With the exception of beliefs about sleep needs (wherein only community sleep clinic patients had high scores relative to good sleepers), all insomnia groups had higher scores on the DBAS-16 than good sleepers. A validity analysis suggested that a DBAS-16 index score > 3.8 was the level of unhelpful beliefs associated with clinically significant insomnia, although a slightly lower cutoff may be useful to identify an unhelpful degree of sleep-related beliefs in highly screened PI and medical patient groups. Conclusions: This study offers descriptive data for the use of the DBAS-16 across insomnia subgroups, which will help the user understand what degree of maladaptive sleep beliefs are most strongly associated with clinically significant levels of insomnia. Results also may have implications for cognitive targeting during treatment for particular insomnia groups. PMID:20004301

The increase in circulating levels of progesterone during pregnancy stimulates production of prostaglandins, especially prostaglandin E2, possibly resulting in pregnancy gingivitis. The purpose of this study is to evaluate the influence of prostaglandin E2 concentrations on gingival tissues in pregnancy and to assess its relationship to clinical parameters. This study evaluates the effects of periodontal treatment on clinical indices including plaque index, gingival index, probing depth, and gingival crevicular fluid prostaglandin E2 levels of 22 pregnant women in their first, second, and third trimesters. Initial periodontal therapy consisting of scaling, root planing, and oral hygiene instruction was performed at the beginning of the first trimester and repeated each trimester. Prostaglandin E2 concentrations in gingival crevicular fluid were determined using a commercially available enzyme immunoassay kit. The statistical tests used were paired sample test and correlation analysis. The results of the study show that periodontal therapy has resulted in an improvement in clinical parameters (P<0.05). There is also a statistically significant decrease in levels of prostaglandin E2 at the second and third trimesters following periodontal therapy (P <0.001). The correlation between prostaglandin E2 concentrations and clinical parameters is found to be non-significant (P >0.05). Our data indicate that levels of prostaglandin E2 in gingival crevicular fluid may be used as a marker of gingival inflammation in order to determine the effects of periodontal therapy in pregnancy. Periodontal therapy that is performed throughout the entire pregnancy period may help prevent the threat of pregnancy gingivitis.

This would enable us to predict the clinical significance of the number of depressive symptoms in MDD patients. Using data from the Clinical Research Center for Depression (CRESCEND) study in Korea, 853 patients with DSM-IV MDD were recruited. The baseline and clinical characteristics of groups with different numbers of depressive symptoms were compared using the χ(2) test for discrete variables and covariance (ANCOVA) for continuous variables. In addition, the scores of these groups on the measurement tools were compared by ANCOVA after adjusting the potential effects of confounding variables. After adjusting the effects of monthly income and history of depression, a larger number of depressive symptoms indicated higher overall severity of depression (F [4, 756] = 21.458, P < 0.001) and higher levels of depressive symptoms (F [4, 767] = 19.145, P < 0.001), anxiety symptoms (F [4, 765] = 12.890, P < 0.001) and suicidal ideation (F [4, 653] = 6.970, P < 0.001). It also indicated lower levels of social function (F [4, 760] = 13.343, P < 0.001), and quality of life (F [4, 656] = 11.975, P < 0.001). However, there were no significant differences in alcohol consumption (F [4, 656] = 11.975, P < 0.001). The number of depressive symptoms can be used as an index of greater illness burden in clinical psychiatry.

Esophageal cancer was a vital cause of cancer-related mortality worldwide, and the insulin-like growth factor-binding proteins (IGFBPs) has been proved to be an important factor of multiple types of tumors. There is a controversy that whether the IGFBP-3 level is associated with the clinical pathological characteristics and overall survival of esophageal cancer patients. Herein, we aimed to comprehensively assess the association between the low IGFBP-3 level and the risk, overall survival and clinical pathological characteristics of esophageal cancer. We conducted a meta-analysis using seven eligible studies. The overall odds ratios (OR)/relative risk (RR) and their corresponding 95% confidence interval (CI) were calculated for each parameter. For the risk of esophageal cancer, the OR was 2.342 (p = 0.000), indicating that individuals with lower IGFBP-3 level were more likely to suffer from esophageal cancer, compared to those with relatively high IGFBP-3 level. With respect to the 3-year survival rate, the RR was 2.163 (p = 0.027), which demonstrated that esophageal cancer patients with low IGFBP-3 level had significantly lower 3-year survival rate; in terms of clinical pathological characteristics, significantly lower IGFBP-3 level was found for patients in all categories; for survival status, patients in low IGFBP-3 level are more likely to be in the dead survival status (OR = 4.480, p = 0.000). Our meta-analysis suggests that for esophageal cancer, the low IGFBP-3 level is associated with high cancer risk, poor prognosis, and unfavorable tumor stage and metastasis.

Standard surgical treatment for symptomatic cervical disc disease has been discectomy and fusion, but the use of arthroplasty, designed to preserve motion, has increased, and most studies report clinical outcome in its favor. Few of these trials, however, blinded the patients. We, therefore, conducted the Norwegian Cervical Arthroplasty Trial, and present 2-year clinical outcome after arthroplasty or fusion. This multicenter trial included 136 patients with single-level cervical disc disease. The patients were randomized to arthroplasty or fusion, and blinded to the treatment modality. The surgical team was blinded to randomization until nerve root decompression was completed. Primary outcome was the self-rated Neck Disability Index. Secondary outcomes were the numeric rating scale for pain and quality of life questionnaires Short Form-36 and EuroQol-5Dimension-3 Level. There was a significant improvement in the primary and all secondary outcomes from baseline to 2-year follow-up for both arthroplasty and fusion (P < 0.001), and no observed significant between-group differences at any follow-up times. However, linear mixed model analyses, correcting for baseline values, dropouts and missing data, revealed a difference in Neck Disability Index (P = 0.049), and arm pain (P = 0.027) in favor of fusion at 2 years. The duration of surgery was longer (P < 0.001), and the frequency of reoperations higher (P = 0.029) with arthroplasty. The present study showed excellent clinical results and no significant difference between treatments at any scheduled follow-up. However, the rate of index level reoperations was higher and the duration of surgery longer with arthroplasty. http://www.clinicaltrials.gov NCT 00735176.19.

Clinical diagnosis and severity of autism spectrum disorders (ASD) are determined by trained clinicians based on clinical evaluations of observed behaviors. As such, this approach is inevitably dependent on the expertise and subjective assessment of those administering the clinical evaluations. There is a need to identify objective biological markers associated with diagnosis or clinical severity of the disorder. To identify novel candidate metabolites as potential biomarkers for ASD, the current study applied capillary electrophoresis time-of-flight mass spectroscopy (CE-TOFMS) for high-throughput profiling of metabolite levels in the plasma of 25 psychotropic-naïve adult males with high-functioning ASD and 28 age-matched typically-developed control subjects. Ten ASD participants and ten age-matched controls were assigned in the first exploration set, while 15 ASD participants and 18 controls were included in the second replication set. By CE-TOFMS analysis, a total of 143 metabolites were detected in the plasma of the first set. Of these, 17 metabolites showed significantly different relative areas between the ASD participants and the controls (p<0.05). Of the 17 metabolites, we consistently found that the ASD participants had significantly high plasma levels of arginine (p = 0.024) and taurine (p = 0.018), and significantly low levels of 5-oxoproline (p<0.001) and lactic acid (p = 0.031) compared with the controls in the second sample set. Further confirmatory analysis using quantification of absolute metabolite concentrations supported the robustness of high arginine (p = 0.001) and low lactic acid (p = 0.003) in the combined sample (n = 53). The present study identified deviated plasma metabolite levels associated with oxidative stress and mitochondrial dysfunction in individuals with ASD.

The aims of the current study were to investigate the betatrophin levels in lean glucose-tolerant women with polycystic ovary syndrome (PCOS), and to explore the relationships between these levels and antropometric, hormonal and metabolic parameters. The study population consisted of 50 lean (body mass index [BMI] < 25 kg/m 2 ) women diagnosed with PCOS using the Rotterdam criteria, and 60 age- and BMI-matched healthy controls without any features of clinical or biochemical hyperandrogenism. Before recruitment, glucose tolerance was evaluated in all of the subjects using the 2-h 75 g oral glucose-tolerance test, and only those exhibiting normal glucose tolerance were enrolled. Serum betatrophin levels were significantly higher in women with PCOS (median 322.3; range 44.7-1989.3 ng/L) compared to the controls (median 199.9; range 6.2-1912.9 ng/L; p = .005). In the control group, no significant correlation was evident between betatrophin levels and clinical or biochemical parameters. In the PCOS group, betatrophin levels were positively correlated with prolactin levels (r = .286, p = .046) and negatively correlated with BMI (r = -.283, p = .049), waist/hip ratio (r = -.324, p = .023), and low-density lipoprotein cholesterol levels (r = -.385, p = .006). Impact statement What is already known on this subject: Several studies have suggested that primary alteration in beta-cell function is a pathophysiological feature of PCOS, and insulin resistance is the most significant predictor of beta-cell dysfunction independent of obesity. Betatrophin is a circulating protein that is primarily expressed in the liver in humans. Early experimental investigations demonstrated that overexpression of betatrophin significantly promoted pancreatic beta-cell proliferation, insulin production and improved glucose tolerance. Few studies have investigated the association between PCOS and betatrophin. However, in contrast to our study, the authors included overweight/obese patients and glucose tolerance was not evaluated before recruitment. What the results of this study add: Our results showed that serum betatrophin levels were significantly higher in lean glucose-tolerant PCOS women than in age- and BMI-matched healthy controls. What are the implications of these findings for clinical practice and/or further research: Elevated betatrophin levels in PCOS women, in the absence of obesity and glucose intolerance, may reflect a compensatory mechanism in order to counteract metabolic syndrome-related risk factors.

Study Design Survey. Objective Sports-related spinal cord injury (SCI) represents a growing proportion of total SCIs but lacks evidence or guidelines to guide clinical decision-making on return to play (RTP). Our objective is to offer the treating physician a consensus analysis of expert opinion regarding RTP that can be incorporated with the unique factors of a case for clinical decision-making. Methods Ten common clinical scenarios involving neurapraxia and stenosis, atlantoaxial injury, subaxial injury, and general cervical spine injury were presented to 25 spine surgeons from level 1 trauma centers for whom spine trauma is a significant component of their practice. We evaluated responses to questions about patient RTP, level of contact, imaging required for a clinical decision, and time to return for each scenario. The chi-square test was used for statistical analysis, with p < 0.05 considered significant. Results Evaluation of the surgeons' responses to these cases showed significant consensus regarding return to high-contact sports in cases of cervical cord neurapraxia without symptoms or stenosis, surgically repaired herniated disks, and nonoperatively healed C1 ring or C2 hangman's fractures. Greater variability was found in recommendations for patients showing persistent clinical symptomatology. Conclusion This survey suggests a consensus among surgeons for allowing patients with relatively normal imaging and resolution of symptoms to return to high-contact activities; however, patients with cervical stenosis or clinical symptoms continue to be a challenge for management. This survey may serve as a basis for future clinical trials and consensus guidelines. PMID:27853664

Since its first occurrence in August 2011 in Germany and the Netherlands, the Schmallenberg virus (SBV) spread rapidly across Europe, where it caused production losses and abortions in ruminants as well as congenital malformations in the offspring of affected animals. Several studies have investigated the impact of SBV on fertility and production parameters in dairy cows at herd level. However, the impact of clinical disease at the animal level remained undetermined. This study aimed at estimating the impact of clinical disease during and after an infection with SBV on production and fertility parameters in individual Swiss dairy cows. Sixty-seven case and twenty-four control herds were selected according to whether cows had been showing clinical signs indicative of SBV during the epidemic from July to December 2012 in Switzerland. Of these 91 farms, production and fertility data from 388 cows with clinical signs from case herds were collected over a time period of four years, and compared to data from 932 cows without clinical signs originating from case or control herds. Milk yield, somatic cell count, number of inseminations and non-return at day 56 were analysed by means of hierarchical multivariable regression analysis. A significant drop in milk yield was observed in all groups during the SBV epidemic compared to the time before the infection, which amounted to 1.9kg per test day for clinical animals, 1.1kg for non-clinical animals from case herds and 0.6kg for non-clinical animals from control herds. A prolonged effect on milk yield was observed in clinical cows for about one year, suggesting that animals with clinical disease might not return to their previous milk production level in the current lactation after an acute infection with SBV. Clinical animals showed a significantly higher somatic cell count during the epidemic compared to the time before the infection. The number of inseminations per cow and production cycle was higher for clinical animals during the epidemic compared to the time periods before and after, but not significantly higher than for non-clinical animals from case and control herds. No difference regarding non-return at day 56 was found. Although the overall impact of the SBV epidemic in Switzerland was limited, the consequences could be substantial in farms with a high prevalence of clinical disease. Copyright © 2017 Elsevier B.V.

Constitutive activation of extracellular signal-regulated kinase (ERK)1/2 pathway, that is activated by various stimuli including growth factors and oncogenic driver mutations, is observed in various cancers. However, the difference of the activated levels of the pathway is still unclear in clinical significances. The aim of this study was to investigate the effect of different ERK1/2 pathway activation, assessed by the expression levels of phosphorylated (p) ERK1/2, on the prognosis of advanced lung adenocarcinoma patients. Paraffin-embedded lung biopsy samples were obtained from 85 lung adenocarcinoma patients. Correlation between pERK1/2 expression levels that were assessed by immunohistochemistry (IHC) analysis and oncogenic driver mutation status, clinicopathological factors, outcome from standard anticancer therapies, and prognosis was investigated. Varying levels of pERK1/2 expression were observed in 68 (80.0 %) patients. The overall survival was significantly reduced in patients with higher pERK1/2 expression in comparison to those with lower expression levels (P = 0.03). In particular, higher pERK1/2 expression levels correlated with worse performance status and worse clinical outcome. Thus, the IHC analysis of pERK1/2 expression levels may predict patient prognosis in advanced lung adenocarcinoma. Inhibition of ERK1/2 pathway activated by various signals may improve the effects of standard chemotherapies and the clinical condition of patients with advanced cancer.

Serologically active clinically quiescent (SACQ) patients with systemic lupus erythematosus (SLE) remain clinically quiescent for prolonged periods despite anti-dsDNA antibodies and/or low complements, indicating the presence of immune complexes. The immune mechanisms leading to this quiescence are unknown. However, in addition to activating complement, immune complex uptake by various cells leads to the production of interferon (IFN)-α and other proinflammatory factors that are also involved in tissue damage. Here we investigate whether production of these factors is reduced in SACQ patients. The levels of 5 IFN-induced genes and 19 cyto/chemokines were measured in SACQ patients and were compared with those in serologically and clinically active (SACA) and serologically and clinically quiescent (SQCQ) patients. SACQ and SQCQ were defined as ≥ 2 years without clinical activity, with/without persistent serologic activity, respectively, and off corticosteroids/immunosuppressives. SACA was defined as disease activity compelling immunosuppression. Levels of OAS1, IFIT1, MX1, LY6E, and ISG15 were measured by quantitative real-time polymerase chain reaction (PCR) and a composite score (IFN-5) derived from this. Plasma cyto/chemokines were measured by Luminex assay. Nonparametric univariate and logistic regression analyses were conducted. There were no differences in gene expression or cyto/chemokine levels between SACQ and SQCQ patients. The SACQ IFN-5 score was significantly lower than that of SACA (p = 0.003) and was driven by SACQ status, not by autoantibody profile or disease duration. Levels of granulocyte-macrophage colony-stimulating factor, interleukin (IL) 6, IL-10, IFN-γ-inducible protein 10, monocyte chemoattractant protein 1, and tumor necrosis factor-α were significantly lower in SACQ than SACA. The levels of proinflammatory factors in SACQ mirror those of SQCQ patients, indicating reduced production of these factors despite the presence of immune complexes.

Mastitis is a disease of major economic importance in dairy industry worldwide. It is of particular concern in developing countries like Ethiopia, where milk and milk products are scarce. The objectives of the study were to estimate the prevalence of mastitis, identify the cow-and herd-level potential risk factors and isolate Staphylococcus aureus, one of etiological agents for contagious mastitis, from cows positive for mastitis. A total of 529 lactating cows selected randomly from 95 herds were screened by California mastitis test (CMT) for sub-clinical mastitis. Also 172 milk samples collected from CMT positive cows were cultured for isolation of S. aureus. Based on CMT result and clinical examination, the prevalence of mastitis at herd-level was 74.7% (95% CI: 64.5, 82.8). The corresponding cow-level prevalence was 62.6% (95% CI: 58.3, 66.7), of which 59.2 and 3.4% were sub-clinical and clinical mastitis cases, respectively. S. aureus was isolated from 51.2% of the milk samples cultured and 73.2% of the herds affected with mastitis. In the multivariable logistic regression model, the herd-level factors significantly associated (p < 0.05) with the presence of mastitis were herd size, bedding material, and milking mastitic cows last, while at cow-level, breed, parity, stage of lactation, udder and leg hygiene, and teat end shape were noted to have a significant effect on mastitis occurrence. The very high prevalence of mastitis, more importantly the sub-clinical one, in the herds examined revealed the huge potential economic loss the sector suffers. Perhaps this was attributed to lack of implementation of the routine mastitis prevention and control practices by all of the herd owners. The findings of this study warrants the need for strategic approach including dairy extension that focus on enhancing dairy farmers' awareness and practice of hygienic milking, regular screening for sub-clinical mastitis, dry cow therapy and culling of chronically infected cows.

To investigate the roles of B-cell lymphoma-2 associated athanogene 3 (BAG3) in human chondrosarcoma and the potential mechanisms, the expression levels of BAG3 were detected in the present study, and the associations between BAG3 and clinical pathological parameters, clinical stage as well as the survival of patients were analyzed. The present study detected BAG3 mRNA and protein expression in the normal cartilage cell line HC-a and in SW1353 chondrosarcoma cells by reverse transcription-quantitative polymerase chain reaction and western blot analysis. The BAG3 protein expression in 59 cases of chondrosarcoma, 30 patients with endogenous chondroma and 8 cases of normal cartilage was semi-quantitatively analyzed using the immunohistochemical method. In addition, the BAG3 protein expression level, the clinical pathological parameters, clinical stage and the survival time of patients with chondrosarcoma were analyzed. The plasmid transfection method was employed to upregulate the expression BAG3 and small RNA interference to downregulate the expression of BAG3 in SW1353 cells. The expression levels of BAG3 protein and mRNA were significantly increased in the chondrosarcoma cell line when compared with the normal cartilage cell line. The immunohistochemistry results indicated that BAG3 protein was overexpressed in the tissue of human chondrosarcoma. Statistical analysis showed that the expression level of BAG3 was significantly increased in the different Enneking staging of patients with chondrosarcoma and Tumor staging, and there were no statistical differences in age, gender, histological classification and tumor size. In the in vitro experiments, the data revealed that BAG3 significantly promoted chondrosarcoma cell proliferation, colony-formation, migration and invasion; however, it inhibited chondrosarcoma cell apoptosis. It was observed that BAG3 upregulated β-catenin expression at the mRNA and protein levels. In addition, BAG3 induced the expression of runt-related transcription factor 2 (RUNX2) in chondrosarcoma cells by upregulating β-catenin. These clinical analyses revealed a positive association between β-catenin and BAG3 in chondrosarcoma tumors. BAG3 was significantly increased in chondrosarcoma cells and tissues compared with the normal cartilage cells, tissue and cartilage benign tumors. Thus, BAG3 may serve as an oncogene in the development of chondrosarcoma via the induction of RUNX2 expression. The results of the present study contribute to further research on the biological development of chondrosarcoma. PMID:29484408

It has been reported that serum levels of KL-6 and surfactant protein D(SP-D) can be useful indicators for interstitial pneumonia(IP). In the present study, we evaluated the clinical significance of KL-6 and SP-D by measuring the serum levels of patients with various pulmonary diseases by enzyme-linked immunosorbent assay. Serum levels of KL-6 in patients with idiopathic interstitial pneumonia(IIP), collagen disease with interstitial pneumonia(CDIP), lung cancer(LC) and LC with idiopathic interstitial pneumonia were significantly higher than of those in healthy controls. Moreover, serum levels of KL-6 were significantly higher in patients with active IP than in those with inactive IP. Serum levels of SP-D in patients with IIP and CDIP were significantly higher than of those in healthy controls. When a cut-off level of KL-6 or SP-D in sera was defined as a value of healthy controls representing the means + 2SD, the serum KL-6 positive diagnostic rate for IP(79.2%) was higher than that of SP-D(66.7%). The SP-D positive diagnostic rate for lung diseases other than IP(11.6%) was lower than that of KL-6(34.9%). The serum concentration of KL-6 in patients with the pulmonary diseases significantly correlated with that of SP-D. These findings suggest that KL-6 may be superior in the sensitivity of IP and can be used to evaluate the disease activity of IP. In addition, SP-D may be more specific for IP than KL-6.

Bryan cervical disc arthroplasty has been reported with satisfactory short- and medium-term clinical results. However, the long-term clinical and radiographic outcomes are seldom reported. The purpose of this study was to compare the eight-year follow-up results in patients who underwent Bryan disc arthroplasty with patients received ACDF, and assess the incidence of heterotopic ossification (HO) and its effect on clinical outcome and mobility of the device. Thirty-one patients underwent Bryan disc arthroplasty, and 35 patients underwent ACDF were included in the study. The Japanese Orthopedic Association (JOA) scores, neck disability index (NDI), visual analogue scale (VAS) of neck and arm pain, and the radiographs were used to evaluate the outcomes. The heterotopic ossification (HO) was determined by CT scan and was classified into three subgroups to compare the related effect. Adjacent segment degeneration (ASD) was also observed. At final follow-up, there were no significant differences in JOA scores between two groups, but the improvement in NDI and neck or arm VAS were significantly greater in the Bryan disc cohort. The range of motion at the index level was 7.0° in Bryan group, while 100 % bone fusion were achieved in ACDF group. HO was observed in 18 (51.4 %) levels. There were more restricted movement of the prosthesis and slight higher rate of axial pain in patients with severe-HO (grade III and IV). Fourteen (28.6 %) levels developed ASD in Bryan group, which was significantly lower than that (58.6 %) in ACDF group. At eight year follow-up, the clinical and radiographic outcomes of Bryan cervical disc arthroplasty compared favorably to those of ACDF. It avoided accelerated adjacent segment degeneration by preserving motion. However, severe HO restricted the ROM of the index levels and maybe associated with post-operative axial pain.

We studied the effect of early antihypertensive treatment on death, major disability, and vascular events among patients with acute ischemic stroke according to their baseline SBP. We randomly assigned 4071 acute ischemic stroke patients with SBP between 140 and less than 220 mmHg to receive antihypertensive treatment or to discontinue all antihypertensive medications during hospitalization. A composite primary outcome of death and major disability and secondary outcomes were compared between treatment and control stratified by baseline SBP levels of less than 160, 160-179, and at least 180 mmHg. At 24 h after randomization, differences in SBP reductions were 8.8, 8.6 and 7.8 mmHg between the antihypertensive treatment and control groups among patients with baseline SBP less than 160, 160-179, and at least 180 mmHg, respectively (P < 0.001 among subgroups). At day 14 or hospital discharge, the primary and secondary outcomes were not significantly different between the treatment and control groups among subgroups. However, there was a significant interaction between antihypertensive treatment and baseline SBP subgroups on death (P = 0.02): odds ratio (95% CI) of 2.42 (0.74-7.89) in patients with baseline SBP less than 60 mmHg and 0.34 (0.11-1.09) in those with baseline SBP at least 180 mmHg. At the 3-month follow-up, the primary and secondary clinical outcomes were not significantly different between the treatment and control groups by baseline SBP levels. Early antihypertensive treatment had a neutral effect on clinical outcomes among acute ischemic stroke patients with various baseline SBP levels. Future clinical trials are warranted to test BP-lowering effects in acute ischemic stroke patients by baseline SBP levels. ClinicalTrials.gov Identifier: NCT01840072.

Despite extensive progress in treatment for cancer in recent decades, the early diagnosis for gastric cancer (GC) and colorectal cancer (CRC) remains poor. In this study, we explore the diagnostic value of joint detection of thymidine kinase 1 (TK1), carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA 19-9) and carbohydrate antigen 72-4 (CA 72-4) in the diagnosis of GC and CRC, and to evaluated the relationship between TK1 expression and clinical pathological characteristics in the patients. Serum TK1, CA 19-9, CA 72-4 and CEA levels were measured in 169 patients with GC, 344 patients with CRC and 75 healthy controls using electro-chemiluminescence. The TK1 concentration was significantly higher in patients with cancer than in healthy controls and patients with clinical stage Ⅲ+Ⅳ had higher TK1 levels than clinical stage Ⅰ+Ⅱ ( P <0.05). The levels of TK1 is significantly associated with tumor stage, lymph node metastasis, distant metastasis, tumor differentiation and age ( P <0.05). When the tumor markers (TK1, CA 19-9 and CA 72-4) were detected respectively, the area under receiver operating characteristics curve (AUC) of TK1 for three cancers was the highest (0.823-0.895). However, the combination of AUC was higher than that for each tumor marker detected respectively (0.934-0.953), and the Hosmer-Lemeshow test showed an adequate model of calibration (P>0.05). Moreover, the AUCs varied significantly between the combination tests and single biomarker tests (Z test, P <0.01). In conclusion, serum TK1 may be an independent tumor marker for GC and CRC patients, and the combination of TK1, CA 19-9 and CA 72-4 and CEA performed even better. This study suggests that combination detection of four tumor markers may prove to be useful for the diagnosis of GC and CRC.

This study aims to assess the differences in the radiological and clinical results depending on the lordotic angles of the cage in posterior lumbar interbody fusion (PLIF). We reviewed 185 segments which underwent PLIF using two different lordotic angles of 4° and 8° of a polyetheretherketone (PEEK) cage. The segmental lordosis and total lumbar lordosis of the 4° and 8° cage groups were compared preoperatively, as well as on the first postoperative day, 6th and 12th months postoperatively. Clinical assessment was performed using the ODI and the VAS of low back pain. The pre- and immediate postoperative segmental lordosis angles were 12.9° and 12.6° in the 4° group and 12° and 12.0° in the 8° group. Both groups exhibited no significant different segmental lordosis angle and total lumbar lordosis over period and time. However, the total lumbar lordosis significantly increased from six months postoperatively compared with the immediate postoperative day in the 8° group. The ODI and the VAS in both groups had no differences. Cages with different lordotic angles of 4° and 8° showed insignificant results clinically and radiologically in short-level PLIF surgery. Clinical improvements and sagittal alignment recovery were significantly observed in both groups. PMID:25685795

Mobile phone technology is being used worldwide to improve follow-ups in health care. Aim of the study is to evaluate whether the use of mobile technology will improve or not the follow-up of Indian patients from a community mental health center. Patients or caregivers having mobile phones and consenting for study were enrolled, and sociodemographic and clinical details of patients were taken. Participants were randomized into two groups (short message service [SMS] vs. non-SMS group). At first intervention level, a SMS was sent to SMS group (not in non-SMS group) 1 day before their appointment. At second-level intervention (voice call level), patients from both groups who missed their first appointment were given a voice call requesting them to come for follow-up, and the reasons for first missed appointments (MA) were also elicited. The effect of these two intervention levels (first SMS for SMS group and next voice calls for both groups) on follow-up was evaluated. A total of 214 patients were enrolled in the study. At first SMS intervention level of SMS group ( n = 106), 62.26% of participants reached appointment-on-time (RA), while in the non-SMS/as usual group ( n = 108), 45.37% of patients RA. The difference of these groups is statistically significant. At second-level intervention (voice call), 66 of 88 (another 15 were unable to contact) were came for follow-up consultation within 2 days of MA. Distance and diagnosis of alcohol dependence were significantly associated with MA. Social reasons were most common reasons for first MA. The use of mobile phone technology in an outpatient community psychiatric clinic improved follow-up significantly.

Investigating the clinical potential for 14-3-3 zeta protein to serve as a biomarker for epithelial ovarian cancer

PubMed Central

2013-01-01

Objective Recently, 14-3-3 zeta protein was identified as a potential serum biomarker of epithelial ovarian cancer (EOC). The goal of this study was to investigate the clinical potential of 14-3-3 zeta protein for monitoring EOC progression compared with CA-125 and HE4. Design Prospective follow-up study. Setting University of Pecs Medical Center Department of Obstetrics and Gynecology/Oncology (Pecs, Hungary). Population Thirteen EOC patients with advanced stage (FIGO IIb-IIIc) epithelial ovarian cancer that underwent radical surgery and received six consecutive cycles of first line chemotherapy (paclitaxel, carboplatin) in 21-day intervals. Methods Pre- and post-chemotherapy computed tomography (CT) scans were performed. Serum levels of CA-125, HE4, and 14-3-3 zeta protein were detected by enzyme-linked immunosorbent assay (ELISA) and quantitative electrochemiluminescence assay (ECLIA). Main outcome measures Serum levels of CA-125, HE4, and 14-3-3 zeta protein, as well as lesion size according to pre- and post-chemotherapy CT scans. Results Serum levels of CA-125 and HE4 were found to significantly decrease following chemotherapy, and this was consistent with the decrease in lesion size detected post-chemotherapy. In contrast, 14-3-3 zeta protein levels did not significantly differ in healthy postmenopausal patients versus EOC patients. Conclusions Determination of CA-125 and HE4 serum levels for the determination of the risk of ovarian malignancy algorithm (ROMA) represents a useful tool for the prediction of chemotherapy efficacy for EOC patients. However, levels of 14-3-3 zeta protein were not found to vary significantly as a consequence of treatment. Therefore we question if 14-3-3 zeta protein is a reliable biomarker, which correlates with the clinical behavior of EOC. PMID:24238270

To assess a novel method for assessing risk and providing advice about activity to children and young people with congenital cardiac disease and their parents. Questionnaire survey in outpatient clinics at a tertiary centre dealing with congenital cardiac disease, and 6 peripheral clinics. Children or their parents completed a brief questionnaire. If this indicated a desire for help, or a serious mismatch between advised and real level of activity, they were telephoned by a physiotherapist. MAIN MEASURES OF OUTCOME: Knowledge about appropriate levels of activity, and identification of the number exercising at an unsafe level, the number seeking help, and the type of help required. 253/258 (98.0%) questionnaires were returned, with 119/253 (47.0%) showing incorrect responses in their belief about their advised level of exercise; 17/253 (6.7%) had potentially dangerous overestimation of exercise. Asked if they wanted advice 93/253 (36.8%) said "yes", 43/253 (17.0%) "maybe", and 117/253 (46.2%) "no". Of those contacted by phone to give advice, 72.7% (56/77) required a single contact and 14.3% (11/77) required an intervention that required more intensive contact lasting from 2 up to 12 weeks. Of the cohort, 3.9% (3/77) were taking part in activities that put them at significant risk. There is a significant lack of knowledge about appropriate levels of activity, and a desire for further advice, in children and young people with congenital cardiac disease. A few children may be at very significant risk. These needs can be identified, and clinical risk reduced, using a brief self-completed questionnaire combined with telephone follow-up from a suitably knowledgeable physiotherapist.

Cerebrospinal fluid markers of neuronal and glial cell damage to monitor disease activity and predict long-term outcome in patients with autoimmune encephalitis.

Clinical symptoms and long-term outcome of autoimmune encephalitis are variable. Diagnosis requires multiple investigations, and treatment strategies must be individually tailored. Better biomarkers are needed for diagnosis, to monitor disease activity and to predict long-term outcome. The value of cerebrospinal fluid (CSF) markers of neuronal [neurofilament light chain protein (NFL), and total tau protein (T-tau)] and glial cell [glial fibrillary acidic protein (GFAP)] damage in patients with autoimmune encephalitis was investigated. Demographic, clinical, magnetic resonance imaging, CSF and antibody-related data of 25 patients hospitalized for autoimmune encephalitis and followed for 1 year were retrospectively collected. Correlations between these data and consecutive CSF levels of NFL, T-tau and GFAP were investigated. Disability, assessed by the modified Rankin scale, was used for evaluation of disease activity and long-term outcome. The acute stage of autoimmune encephalitis was accompanied by high CSF levels of NFL and T-tau, whereas normal or significantly lower levels were observed after clinical improvement 1 year later. NFL and T-tau reacted in a similar way but at different speeds, with T-tau reacting faster. CSF levels of GFAP were initially moderately increased but did not change significantly later on. Final outcome (disability at 1 year) directly correlated with CSF-NFL and CSF-GFAP levels at all time-points and with CSF-T-tau at 3 ± 1 months. This correlation remained significant after age adjustment for CSF-NFL and T-tau but not for GFAP. In autoimmune encephalitis, CSF levels of neuronal and glial cell damage markers appear to reflect disease activity and long-term disability. © 2016 EAN.

Alveolar bone level changes in maxillary expansion treatments assessed through CBCT.

PubMed

Pham, Vi; Lagravère, Manuel O

2017-03-01

Determine changes in alveolar bone levels during expansion treatments as assessed through cone-beam computer tomography (CBCT). Sixty-one patients from Edmonton, Canada, with maxillary transverse deficiencies were split into three groups. One group was treated with a bone-anchored expander, another group was treated with a tooth-borne maxillary expander (Hyrax) and one group was untreated. CBCTs were obtained from each patient at two time points (initialT 1 and at removal of appliance after 6 months T 2 ). CBCTs were analyzed using AVIZO software and landmarks were placed on different dental and skeletal structures. Intra-examiner reliability for landmarks was done by randomly selecting 10 images and measuring each landmark 3 times, 1 week apart. Descriptive statistics, intraclass correlation coefficients (ICC) and ANOVA analysis were used to determine if there were changes to the alveolar bone levels and if these changes were statistically significant within each group. Landmarks reliability showed an ICC of at least 0.99 with a 95% confidence interval and a mean measurement error of at least 0.2067mm. Descriptive statistics show that changes in alveolar bone levels were less than 1mm for all three groups and therefore clinically insignificant. Changes between groups were not statistically different (P<0.05) from one another with the exception of 8 distances. However, since the distances were small, they were not considered clinically significant. Alveolar bone level changes were similar in maxillary expansion treatments and in the control group. The effects of maxillary expansion treatments on alveolar bone levels are not clinically significant. Copyright © 2016 CEO. Published by Elsevier Masson SAS. All rights reserved.

To measure fatigue and physical functioning in patients with end stage renal disease (ESRD) receiving haemodialysis and to investigate the relationships between fatigue and physical functioning. Fatigue and reduced physical functioning are among the most bothersome symptoms experienced by individuals receiving haemodialysis for ESRD. Research has shown that increasing activity levels has resulted in decreased fatigue levels and improved physical functioning in individuals with cancer. Establishing whether or not a relationship exists between both concepts in haemodialysis patients is a preliminary step in identifying potential fatigue reducing strategies necessary for improved wellbeing. A quantitative exploratory correlational design was used with 46 individuals completing the Multi-dimensional Fatigue Inventory, the Medical Outcomes Study Short-Form 36-item questionnaire and a Demographic Questionnaire. Results indicated fatigue was prevalent with highest scores achieved for physical fatigue; reduced activity and general fatigue. Substantial limitations in physical functioning were found. A significant moderate negative relationship between general fatigue and physical functioning indicated that, as physical functioning levels increased, fatigue levels decreased. A significant difference was also found between general fatigue scores for males and females. Significant relationships were found between overall physical functioning, older age and employment status. The research indicates the prevalence of fatigue and limitations in physical functioning in individuals with ESRD. However, as physical functioning increased fatigue decreased; a finding relevant to clinical nursing. Understanding the levels of fatigue and the value of exercise is of relevance to clinical practice thus assessment of fatigue and physical functioning ability in the clinical setting is necessary.

The primary objective of the present study was to further elucidate the effects of oxcarbazepine (OXC) and levetiracetam (LEV) monotherapies on the bone health status of patients with epilepsy. This study included 48 patients who attended our epilepsy outpatient clinic, had a diagnosis of epilepsy, and were undergoing either OXC or LEV monotherapy and 42 healthy control subjects. The demographic and clinical features of the patients, including gender, age, onset of disease, daily drug dosage, and duration of disease, were noted. Additionally, the calcium, ionized calcium, and 25-OH vitamin-D3 levels of the participants were prospectively evaluated. The 25-OH vitamin-D3, calcium, and ionized calcium levels of the patients taking OXC were significantly lower than those of the control group. These levels did not significantly differ between the patients taking LEV and the control group, but there was a significant negative relationship between daily drug dose and ionized calcium levels in the LEV patients. In the present study, anti-epileptic drugs altered the calcium, ionized calcium, and 25-OH vitamin-D3 levels of epilepsy patients and resulted in bone loss, abnormal mineralization, and fractures. These findings suggest that the calcium, ionized calcium, and 25-OH vitamin-D3 levels of patients with epilepsy should be regularly assessed.

Muscle toxicity is the most significant adverse effect related to statins. The aim of the study was to analyse the clinical course and achievement of LDL-C target levels in patients with statin-induced muscle toxicity. All patients who were referred to the lipid clinic because of statin-induced muscle toxicity, or developed it during follow-up, or did not reach LDL-C target levels because of its previous occurrence, and attended the clinic for at least three follow-up visits, were eligible. Files were reviewed for demographic and clinical parameters, coronary heart disease risk level, the severity of muscle injury, the type of statin and dose that caused the adverse effects, the clinical approach and outcome, and whether the LDL-C target level was achieved. The study group consisted of 54 patients. Twenty-three (43%) patients complained of myalgia, 23 (43%) had asymptomatic serum creatine kinase (CK) level elevation, five (9%) had myopathy and three (5%) had rhabdomyolysis. Fifty of the patients (93%) continued statin therapy and 43 (80%) achieved the LDL-C target level. We show that for the majority of patients with statin-induced muscle toxicity, statin therapy can be safely and effectively continued. In cases of asymptomatic CK levels <3-5 upper limit of normal (ULN), statin treatment should not be interrupted. When CK levels >3-5 ULN or when various symptomatic muscle adverse reactions are present, statins rechallenge, after a recovery period, should be individualized either by a low dose of a potent statin or by a less potent statin. An additional lipid medication is advised if the target levels are not achieved. © 2011 Blackwell Publishing Ltd.

Benign Paroxysmal Positional Vertigo (BPPV) is the most common cause of dizziness in the general population. It is a condition with potential impact of reduced levels of vitamin D on its recurrent attacks. The aim of this study was to measure the serum levels of 25-hydroxyvitamin D3 (25-OH D3) in patients with BPPV and determine whether there is a difference in the serum levels of vitamin D3 between patients with and without recurrence, as well as between the different clinical forms of BPPV. The study included 40 patients who came to the regular medical examination, diagnosed with PC-BPPV based on the positive Dix-Hallpike's test. All patients underwent Epley manoeuvre after the diagnosis. Patients were classified according to current guidelines for levels of vitamin D3 in the serum in three groups: the deficiency, insufficiency and adequate level. The average serum level of 25-OH D3 among respondents was 20.78ng/mL, indicating a lack or insufficiency of the aforementioned 25-OH D3. According to the levels of 25-OH D3, most patients suffer from deficiency (47.5%). 7 (17.5%) respondents had adequate blood level of 25-OH D3, and 14 (35%) respondents suffer from insufficiency. A significant difference was not found in the serum level of 25-OH D3 between patients with and without BPPV recurrence. There was a significant difference in the serum levels of 25-OH D3 in comparison to the clinical form of the disease. Lower 25-OH D3 values were found in patients with canalithiasis compared to those with cupulolithiasis. There were no significant differences in the vitamin D3 serum level in patients with and without recurrence. The study showed a low level of serum vitamin D3 in most patients, indicating the need for supplemental therapy.

This study evaluated the effect of a simplified informed consent form for clinical trials on the understanding and efficacy of informed consent information across health literacy levels. A total of 150 participants were randomly assigned to one of two groups and provided with either standard or simplified consent forms for a cancer clinical trial. The features of the simplified informed consent form included plain language, short sentences, diagrams, pictures, and bullet points. Levels of objective and subjective understanding were significantly higher in participants provided with simplified informed consent forms relative to those provided with standard informed consent forms. The interaction effects between type of consent form and health literacy level on objective and subjective understanding were nonsignificant. Simplified informed consent was effective in enhancing participant's subjective and objective understanding regardless of health literacy. © The Author(s) 2015.

Programmed cell death-ligand 1 (PD-L1) expressed in tumor tissues is a key molecule for immune suppression, given its role in immune checkpoints. The significance and implication of soluble PD-L1 (sPD-L1) in the blood of lung cancer patients remain unknown. Blood samples were prospectively collected from patients with advanced lung cancer, and the plasma sPD-L1 concentrations were measured by enzyme-linked immunosorbent assay. The correlations of the plasma sPD-L1 levels with clinico-pathological status, laboratory data, and survival of the patients were analyzed. Ninety-six patients with advanced lung cancer were analyzed, including 73 with adenocarcinoma, 12 with squamous cell carcinoma, and seven with small-cell lung cancer. Sixty-five were naïve to chemotherapy, and 20 had received two or more lines of chemotherapy. The mean plasma sPD-L1 concentration of all the patients was 6.95±2.90ng/ml (range 2.30-20.0ng/ml), and this value is significantly increased compared with that previously reported for normal subjects. No correlation of the plasma sPD-L1 level with histological subtypes, adenocarcinoma genetic status, smoking history, clinical stage or laboratory data was found. However, overall survival was significantly reduced in patients with high (≥7.32ng/ml) compared with low (<7.32ng/ml) plasma sPD-L1 levels (13.0 vs. 20.4 months, p=0.037). Multivariate analysis revealed that high sPD-L1 levels were significantly related to poor prognosis (hazard ratio 1.99, p=0.041). High plasma sPD-L1 levels were associated with poor prognosis in patients with advanced lung cancer, possibly associated with suppression of anti-tumor immunity.

Objective To investigate the clinical and antenatal sonographic characteristics of placenta previa accreta after cesarean section. Methods The data of 21 inpatients diagnosed as placenta previa accreta after cesarean section in PUMC Hospital from 2006 to 2016 were retrospectively reviewed. The clinical and ultrasound features were recorded and compared among three placental accreta groups,including placenta accrete group(n=5),increta group(n=12),and percreta group(n=4). The relationship between the placental thickness at the uterine anterior lower segment level and the blood loss of the following cesarean section was tested. Results Of 21 patients,placenta previa was diagnosed by ultrasound in 20 cases(95.2%) and placenta previa accreta was diagnosed in 9 cases(42.9%). Antenatal ultrasound findings included following signs:loss of "clear zone"(15/18,83.3%),myometrial thinning(12/18,66.7%),abnormal placental lacunae(12/19,63.2%),bladder wall interruption(2/18,11.1%),and uterovesical hypervascularity(4/9,44.4%). Myometrial thinning(J-T=64.000,P=0.036),abnormal placental lacunae(J-T=74.500,P=0.032) and the placental thickness at the uterine anterior lower segment level(U=83.000,P=0.010) showed significant difference among different placenta accreta groups. Placental thickness at the uterine anterior lower segment level showed linear correlation with the blood loss of the following cesarean section(r=0.669,P=0.002). The blood loss of the following cesarean section showed significant difference among different placenta accreta groups(U=118.500,P=0.000). Conclusions The clinical and sonographic manifestations of placenta previa accreta after cesarean section show a spectrum of demographic characteristics. The measurement of thickness of placenta at the anterior lower segment may help the evaluation of the clinical prognosis of this special pathology.

The aim of this study was to survey the exact benefit of this herb in the management of clinical and laboratory signs and symptoms of allergic rhinitis. In a randomized double blind clinical trial, 74 patients with the signs and symptoms of allergic rhinitis and a positive skin prick test were selected and randomly divided into 2 groups who were taken Urtica dioica 150-mg, Urtidin® F.C Tablet) or placebo for one month. Their signs and symptoms, eosinophil percentage on nasal smear, serum IgE, and interleukin IL-4, IL-5, interferon- γ) levels were recorded. Forty patients completed the trial. Based on the Sino- Nasal Outcome Test 22 SNOT-22), a significant improvement in clinical symptom severity was observed in both groups P < .001). Furthermore, a statistically significant reduction in mean nasal smear eosinophil count was observed after treatment with Nettle P < .01). However, the mean IgE and IL4 and IL5 levels in the study group before and after treatment with Nettle saw no significant changes P > .1). Intergroup pre- and post-treatment laboratory findings suggested that there was a significant difference in post-treatment changes of mean IFN γ levels between the study and placebo group P = 0.017). Although the current study showed certain positive effects of Nettle in the management of allergic rhinitis on controlling the symptoms based on the SNOT-22, similar effects were demonstrated by placebo as well. We believe that our limitations underscore the need for larger, longer term studies of Nettle for the treatment of allergic rhinitis. PMID:29844782

There are many new low-level laser technologies that have been released commercially that claim to support hair regrowth. In this paper, we will examine the clinical trials to determine whether the body of evidence supports the use of low-level laser therapy (LLLT) to treat androgenic alopecia (AGA). A literature search was conducted through Pubmed, Embase, and Clinicaltrials.gov for clinical trials using LLLT to treat AGA. Thirteen clinical trials were assessed. Review articles were not included. Ten of 11 trials demonstrated significant improvement of androgenic alopecia in comparison to baseline or controls when treated with LLLT. In the remaining study, improvement in hair counts and hair diameter was recorded, but did not reach statistical significance. Two trials did not include statistical analysis, but showed marked improvement by hair count or by photographic evidence. Two trials showed efficacy for LLLT in combination with topical minoxidil. One trial showed efficacy when accompanying finasteride treatment. LLLT appears to be a safe, alternative treatment for patients with androgenic alopecia. Clinical trials have indicated efficacy for androgenic alopecia in both men and women. It may be used independently or as an adjuvant of minoxidil or finasteride. More research needs to be undertaken to determine the optimal power and wavelength to use in LLLT as well as LLLT's mechanism of action.

Citrullus colocynthis (L.) Schrad fruit is an herbal medicine used by traditional herbalists for the treatment of diabetes in Iran. To determine its efficacy and toxicity, a 2 month clinical trial was conducted in 50 type II diabetic patients. Two groups of 25 each under standard antidiabetic therapy, received 100 mg C. colocynthis fruit capsules or placebos three times a day, respectively. The patients were visited monthly and glycosylated hemoglobin (HbA1c), fasting blood glucose, total cholesterol, LDL, HDL, triglyceride, aspartate transaminase, alanine transaminase, alkaline phosphatase, urea and creatinine levels were determined at the beginning and after 2 months. The results showed a significant decrease in HbA1c and fasting blood glucose levels in C. colocynthis treated patients. Other serological parameters levels in both the groups did not change significantly. No notable gastrointestinal side effect was observed in either group. In conclusion, C. colocynthis fruit treatment had a beneficial effect on improving the glycemic profile without severe adverse effects in type II diabetic patients. Further clinical studies are recommended to evaluate the long-term efficacy and toxicity of C. colocynthis in diabetic patients. Copyright 2009 John Wiley & Sons, Ltd.

Acute normovolemic hemodilution is safe in neurosurgery.

To determine the safety of acute normovolemic hemodilution (ANH) for patients undergoing neurosurgical procedures. A group of 100 patients undergoing neurosurgical procedures was assigned prospectively to receive ANH. A group of 47 patients who underwent craniotomy for aneurysm clipping and standard anesthetic management was used as a control. Procedures conducted under ANH were performed without significant variations in physiologic parameters. Compared with controls, intraoperative blood loss, operative time, incidence and grade of complications, and length of hospital stay were similar between the two groups. Although the ANH group showed a difference in prothrombin levels before and after hemodilution procedures, the levels were still considered within physiologic parameters. Platelet counts and partial thromboplastin time (PTT) levels indicated no significant variations in either group. During the ANH procedure, a considerable reduction of brain oxygen extraction was observed in individuals with worse preoperative neurologic status (P < 0.05), indicating potential benefit. Among patients with cerebral aneurysm, patients with good initial clinical grades had better clinical results as indicated by Glasgow Outcome Scale scores (P < 0.02). ANH is a safe procedure for patients undergoing neurosurgical procedures. Further studies are necessary to confirm the improvement in brain oxygen extraction and the clinical impact. Nonetheless, patients undergoing aneurysm clipping with good clinical grades seem to profit from ANH. Copyright © 2013 Elsevier Inc. All rights reserved.

Background: Survivin and monoamine oxidase A (MAOA) levels are elevated in prostate cancer (PCa) compared to normal prostate glands. However, the relationship between survivin and MAOA in PCa is unclear. Methods: We examined MAOA expression in the prostate lobes of a conditional PTEN-deficient mouse model mirroring human PCa, with or without survivin knockout. We also silenced one gene at a time and examined the expression of the other. We further evaluated the combination of MAOA inhibitors and survivin suppressants on the growth, viability, migration and invasion of PCa cells. Results: Survivin and MAOA levels are both increased in clinical PCa tissues and significantly associated with patients' survival. Survivin depletion delayed MAOA increase during PCa progression, and silencing MAOA decreased survivin expression. The combination of MAOA inhibitors and the survivin suppressants (YM155 and SC144) showed significant synergy on the inhibition of PCa cell growth, migration and invasion with concomitant decrease in survivin and MMP-9 levels. Conclusions: There is a positive feedback loop between survivin and MAOA expression in PCa. Considering that survivin suppressants and MAOA inhibitors are currently available in clinical trials and clinical use, their synergistic effects in PCa support a rapid translation of this combination to clinical practice.

Retail clinics are largely staffed by nurse practitioners (NPs) and are a popular destination for nonemergent care. We examined if there was a relationship between NP practice regulations and retail clinic growth after the passage of a scope of practice (SOP) reform bill in Pennsylvania. General linear regression models were used to compare retail clinic openings in Pennsylvania, New Jersey, and Maryland between 2006 and 2013. From 2006 to 2008, Pennsylvania experienced a significant growth rate in net retail clinic openings per capita (p = .046), whereas New Jersey and Maryland experienced no significant increase (p = .109 and .053, respectively). From 2009 to 2013, Pennsylvania opened 0.20 clinics (p = .129), New Jersey opened 0.23 clinics (p = .086), and Maryland opened 0.34 clinics per capita per year (p = .017). Our study of three states with varying levels of SOP restraint reveals an association between relaxation of practice regulations and retail clinic growth. Copyright © 2016 Elsevier Inc.

Purpose Retroillumination photography analysis (RPA) provides objective assessment of the number and distribution of guttae in Fuchs Corneal Dystrophy. Here, we assess its correlation with clinical grading using slit-lamp biomicroscopy across varying levels of severity. Methods Retroillumination photographs were conducted of 95 affected corneas with slit-lamp flash photography after pupillary dilation. Individual guttae were counted manually and the position of individual points recorded. Clinical grading using the Krachmer scale was documented for each eye during examination, and regression analyses were performed to identify the strength of association with number of guttae. We assessed range at each stage of clinical grading, and utilized the Mann-Whitney U test to assess whether clinical grading levels demonstrated successively higher numbers of guttae. Results Krachmer score ranged from 1 to 5, with mean of 2.6. Mean numbers of guttae at each level of severity were 289 (1+), 999 (2+), 2669 (3+), 5474 (4+), and 7133 (5+). Each stage demonstrated significantly higher numbers of guttae than its preceding level except from 4+ to 5+ (p=0.30), consistent with the definition of 4+ as the highest level defined by presence of guttae. Higher levels of clinical grading were associated with larger ranges of guttae (p<0.01). A linear regression model resulted in a strong fit between RPA and Krachmer score (r=0.81). Conclusion In this largest study of RPA data and comparison with subjective clinical grading of FCD severity, RPA correlates strongly and demonstrates enhanced definition of severity at advanced stages of disease.

Twelve patients (age 43.4 +/- 6.3 years) with episodic cluster headache (CH) were examined during the cluster period. Plasma norepinephrine levels in patients suffering from CH were significantly decreased compared with the control group (p < 0.01). There were also statistically significant correlations between norepinephrine levels and clinical features of the pain attacks including duration (r = 0.75, p < 0.05), intensity (r = 0.64, p < 0.05) and frequency (r = 0.68, p < 0.06), thereby suggesting a pathophysiological involvement of the sympathetic nervous system in CH. Increased plasma levels of plasmacortisol and ACTH in patients with CH, especially in the morning and in the evening, suggest an alteration of the feedback circuit involving the hypothalamus, the pituitary and the adrenal gland, an imbalance in the hormones related to these structures, as well as an alteration of the circadian rhythm. In addition, CH patients demonstrated significantly decreased levels of norepinephrine (p < 0.05), HVA (p < 0.01) and 5-HIAA (p < 0.01) in the cerebrospinal fluid (CSF) consistent with a central genesis of CH. These significant relationships between neurochemical parameters and the clinical patterns suggest a complex interplay between the hypothalamus, neuroendocrinological parameters, activity of the autonomic nervous system and the pain of CH.

The goal of this work was to determine whether there are clinically significant fluctuations in the level of serum creatinine on serial determinations, especially in the borderline range (1.1-1.3 mg/dl), after specimen storage. Sixty-one serum samples were analyzed. They were divided into three categories based on the initial serum creatinine measurement: low (≤1.0 mg/dl), borderline (1.1-1.3 mg/dl), and high (≥1.4 mg/dl). The specimens were stored at 4°C and run on the Siemens Advia 1800 chemistry analyzer on days 1, 3, and 11. Statistical comparisons of the three groups were made using the unpaired t-test, yielding a two-tailed P-value for each group comparison. The P-values ranged from 0.0829 to 0.3892, indicating no statistically significant difference between the standard deviations of each group. Mild-to-moderate fluctuations in precision occur in successive serum creatinine determinations. The overwhelming majority of these fluctuations should not affect clinical decision making. © 2016 Wiley Periodicals, Inc.

1. Plasma Homovanillic Acid (p HVA) levels were measured by HPLC (high performance liquid chromatography) in 5 schizo-affective depressed patients receiving a standardized treatment. (lithium, chlorpromazine and clomipramine) during 4 weeks. 2. Four patients were pretreated, without a washout period. 3. No significant difference was observed between patients and normal controls at baseline. Under treatment, pHVA levels increased (p<0.02) with clinical improvement (MADRS and PANSS scores). 4. Although effects of medications prior to the study period were not controlled, these findings suggest that depressed schizo-affective patients may have normal pHVA levels that increase with clinical improvement, unlike schizophrenic patients whose increased pHVA concentrations decline with neuroleptic treatment.

There is evidence that some ovarian tumours evoke an immune response, which can be assessed by tumour infiltrating lymphocytes (TILs). To facilitate adoption of TILs as a clinical biomarker, a standardised method for their H&E visual evaluation has been validated in breast cancer. We sought to investigate the prognostic significance of TILs in a study of 953 invasive epithelial ovarian cancer tumour samples, both primary and metastatic, from 707 patients from the prospective population-based SEARCH study. TILs were analysed using a standardised method based on H&E staining producing a percentage score for stromal and intratumoral compartments. We used Cox regression to estimate hazard ratios of the association between TILs and survival. The extent of stromal and intra-tumoral TILs were correlated in the primary tumours (n = 679, Spearman's rank correlation = 0.60, P < 0.001) with a similar correlation in secondary tumours (n = 224, Spearman's rank correlation = 0.62, P < 0.001). There was a weak correlation between stromal TIL levels in primary and secondary tumour samples (Spearman's rank correlation = 0.29, P < 0.001) and intra-tumoral TIL levels in primary and secondary tumour samples (Spearman's rank correlation = 0.19, P = 0.0094). The extent of stromal TILs differed between histotypes (Pearson chi2 (12d.f.) 54.1, P < 0.0001) with higher levels of stromal infiltration in the high-grade serous and endometriod cases. A significant association was observed for higher intratumoral TIL levels and a favourable prognosis (HR 0.74 95% CI 0.55-1.00 p = 0.047). This study is the largest collection of epithelial ovarian tumour samples evaluated for TILs. We have shown that stromal and intratumoral TIL levels are correlated and that their levels correlate with clinical variables such as tumour histological subtype. We have also shown that increased levels of both intratumoral and stromal TILs are associated with a better prognosis; however, this is only statistically significant for intratumoral TILs. This study suggests that a clinically useful immune prognostic indicator in epithelial ovarian cancer could be developed using this technique.

How patient-centered are two included specialized endometriosis clinics relative to each other and how can they improve the patient-centeredness of their care? The validated ENDOCARE questionnaire (ECQ) reliably concluded that the adjusted overall patient-centeredness did not differ between the clinics, that each clinic was significantly more patient-centered for 2 out of 10 dimensions of patient-centered endometriosis care and that clinics 1 and 2 had to improve 8 and 13 specific care aspects, respectively. Patient-centered endometriosis care is essential to high-quality care and is defined by 10 dimensions. The ECQ was developed, validated and proved to be reliable in a European setting of self-reported endometriosis patients but had not yet been used at a clinic level for quality management. A cross-sectional survey was disseminated in 2011 to all 514 women diagnosed with endometriosis during a laparoscopy indicated for pain and/or infertility during a retrospective 2-year period (2009-2010) in two university clinics from two different European countries. In total 337 patients completed the ECQ (216 and 121 per clinic). Respondents had a mean age of 34.3 years. Three in four reported a surgical diagnosis of moderate or severe endometriosis and the majority reported surgical treatment by a multidisciplinary team. The ECQ assessed the 10 dimensions of patient-centeredness, more specifically whether the health-care performance, as perceived by patients, measured up to what is important to patients in general. The ECQ was completed by 337 respondents (response rate = 65.6%). Reliability and validity of the ECQ for use on clinic level were confirmed. Clinics did not differ in overall mean importance scores; importance rankings of the ECQ dimensions were almost identical. The overall patient-centeredness scores (PCS), adjusted for education level, did not discriminate between the clinics. However, the adjusted PCS for the dimensions 'clinic staff' and 'technical skills' were significantly better in clinic 1, whereas the dimensions 'physical comfort' and 'access to care' were significantly better in clinic 2. There were 8 (clinic 1) and 13 (clinic 2) targets identified for joint and cross-clinic improvement. Response rates were relatively high. Recall bias was the most important limitation and research in more clinics is needed to define the statistical discriminative value of the ECQ. European endometriosis clinics can use the validated ECQ for reliable assessment of their 'patient-centeredness', for comparison with others and for setting specific targets to improve the patient-centeredness of their endometriosis care, to plan interventions, and to evaluate their effectiveness.

Physiological changes and immunological modifications occur during pregnancy. The clinical and biological features of periodontal infections are affected by pregnancy. The aim of the present study was to evaluate saliva levels of 25-hydroxy-vitamin D3 (25(OH)D3), prostaglandin E2 (PGE2) and TNF-alpha (TNF-α) in pregnancy, postpartum and non-pregnant controls. Whole saliva samples together with full-mouth clinical periodontal recordings were obtained from 59 pregnant, 47 post partum and 70 systemically healthy non-pregnant women. Groups were also evaluated according to the periodontal health status. 25(OH)D3, PGE2 and TNF-α levels in the saliva samples were determined by enzyme-linked immunoassays. Data were statistically tested by nonparametrical tests. Saliva TNF-α and PGE2 levels were significantly lower and 25(OH)D3 levels were significantly higher in the pregnant group than postpartum group (p<0.0001). Saliva TNF-α and 25(OH)D3 levels were significantly higher and PGE2 levels were significantly lower in the control group than postpartum group (p<0.0001). In the pregnant healthy, gingivitis and periodontitis groups saliva TNF-α levels were significantly lower than postpartum and control counterparts (p<0.0001, p=0.032, p=0.003 and p=0.013; p=0.027; p=0.007, respectively). In control healthy, gingivitis and periodontitis groups saliva 25(OH)D3 levels were significantly higher than the postpartum counterparts (p<0.0001, p<0.0001, p=0.002, respectively). In the control healthy and gingivitis groups saliva 25(OH)D3 levels were significantly higher than pregnant healthy and gingivitis (p<0.0001). In conclusion, within the limits of the present study it seems that pregnancy have an effect on parameters in saliva in relation to the periodontal status of the women. Further studies are required for better understanding of the impact of periodontal diseases on pregnancy or otherwise. Copyright © 2015 Elsevier Ltd. All rights reserved.

To compare retrospectively the clinical and radiographic outcomes between cervical reconstruction with expandable cylindrical cage (ECC) and iliac crest autograft after one- or two-level anterior cervical corpectomy for spondylotic myelopathy. Forty-two patients underwent cervical reconstruction with either iliac crest autograft and plating (20 patients) or ECC and plating (22 patients). The average clinical and radiological follow-up period was 77.54 ± 44.28 months (range 14-155 months). The authors compared clinical parameters (Nurick Myelopathy Grade, modified Japanese Orthopedic Association (mJOA) scores), perioperative parameters (hospital stays, complications) and radiological parameters (Cobb's angles of the fused segments and C2-C7 segments, cervical subsidence, fusion rate). Fusion was assessed on flexion-extension X-ray films. No significant differences between the two groups were found in demographics, neurological presentation, preoperative sagittal alignment, clinical improvement and length of hospitalization. Patients of the autograft group experienced more postoperative complications, although the difference between the two treatment groups was not statistically significant (15 versus 4.5%, p=0.232). The fusion rate was 100% in both groups. The average lordotic increase of the segmental angle was significantly greater in the ECC group (p<0.05). Other radiological parameters were not significantly different in the two groups. Cervical reconstruction either with iliac crest autograft and plating or ECC and plating provides good clinical results and similar fusion rates after one- or two-level corpectomy for spondylotic myelopathy. However, the use of ECC obviates donor site complications and provides a more significant increase of lordosis in segmental angle. Copyright © 2015 Elsevier B.V. All rights reserved.

To investigate the combined use of intravoxel incoherent motion (IVIM) diffusion-weighted (DW) and blood oxygen level dependent (BOLD) magnetic resonance imaging (MRI) to assess rat renal function using a 1.5T clinical platform. Multiple b-value DW and BOLD MR images were acquired from adult rats using a parallel clinical coil arrangement, enabling quantitation of the apparent diffusion coefficient (ADC), IVIM-derived diffusion coefficient (D), pseudodiffusion coefficient (D*) and perfusion fraction (f), and the transverse relaxation time T 2 *, for whole kidney, renal cortex, and medulla. Following the acquisition of two baseline datasets to assess measurement repeatability, images were acquired following i.v. administration of hydralazine, furosemide, or angiotensin II for up to 40 min. Excellent repeatability (CoV <10 %) was observed for ADC, D, f and T 2 * measured over the whole kidney. Hydralazine induced a marked and significant (p < 0.05) reduction in whole kidney ADC, D, and T 2 *, and a significant (p < 0.05) increase in D* and f. Furosemide significantly (p < 0.05) increased whole kidney ADC, D, and T 2 *. A more variable response to angiotensin II was determined, with a significant (p < 0.05) increase in medulla D* and significant (p < 0.05) reduction in whole kidney T 2 * established. Multiparametric MRI, incorporating quantitation of IVIM DWI and BOLD biomarkers and performed on a clinical platform, can be used to monitor the acute effects of vascular and tubular modulating drugs on rat kidney function in vivo. Clinical adoption of such functional imaging biomarkers can potentially inform on treatment effects in patients with renal dysfunction.

To compare the methodologic quality and study/report characteristics between quantitative clinical nursing and nursing education research articles. The methodologic quality of quantitative nursing education research needs to advance to a higher level. Clinical research can provide guidance for nursing education to reach this level. One hundred quantitative clinical research articles from-high impact journals published in 2007 and 37 education research articles from high impact journals published in 2006 to 2007 were chosen for analysis. Clinical articles had significantly higher quality scores than education articles in three domains: number of institutions studied, type of data, and outcomes. The findings indicate three ways in which nursing education researchers can strengthen the methodologic quality of their quantitative research. With this approach, greater funding may be secured for advancing the science of nursing education.

Proximal femoral deformity related to physis has not been studied in patients with cerebral palsy (CP). This study was performed to investigate the clinical relevance of neck shaft angle (NSA), head shaft angle (HSA), and proximal femoral epiphyseal shape in patients with CP, which represent the deformities of metaphysis, physis, and epiphysis, respectively. Three hundred eighty-four patients with CP (mean age 9.1 y, 249 males and 135 females) were included. Extent of involvement and functional states [Gross Motor Function Classification System (GMFCS) level] were obtained. Radiographic measurements including NSA, HSA, and qualitative shape of the proximal femoral epiphysis were evaluated and analyzed according to extent of involvement and GMFCS level. Reliability and correlation with each measurement were assessed. Multiple regression test was performed to examine the significant contributing factors to migration percentage (MP) that represents hip instability. NSA showed excellent interobserver reliability with intraclass correlation coefficients of 0.976. Correlation with the MP was higher in the NSA (r=0.419, P<0.001) than in the HSA (r=0.256, P<0.001). NSA, HSA, and MP tended to increase with increasing GMFCS level, and proportion of valgus deformed proximal femoral epiphysis also increased with increasing GMFCS level, which means valgus deformity and unstable hips in the less favorable functional states. Multiple regression analysis revealed NSA, GMFCS level, and shape of the proximal femoral epiphysis to be significant factors affecting MP. NSA appeared to be more clinically relevant than HSA in evaluating proximal femoral deformity in patients with CP. Shape of proximal femoral epiphysis is believed to have clinical implications in terms of hip instability. Diagnostic level II.

The pathogenesis of seborrheic dermatitis has not been fully elucidated. A number of anascogenic yeasts of Malassezia spp. appear to be involved in the intensity of the symptoms. The purpose of the study is to evaluate the levels of selected inflammatory cytokines, IL-2, IL-4, IFN-γ and TNF-α, in the serum after treatment with itraconazole. Sixty-six subjects were enrolled in the study. The control group consisted of 30 participants (23 females and 7 males) without any clinical disorders, aged 24-65 (37.41±6.08 years). Thirty-six patients with seborrheic dermatitis (16 females and 20 males), aged 19-76 (38.61±13.77), constituted the study group. The measurement of IL-2, IL-4, IFN-γ and TNF-α levels was performed by ELISA using a Human High Sensitivity kit (Diaclone, France). After six-week treatment with itraconazole administered daily at a dose of 200 mg using pulse therapy, there was remission of the disease or at least substantial clinical improvement in the patients with seborrheic dermatitis. The levels of IL-2 and IFN-γ cytokines in the study group were higher than in the control group. After the treatment the level of IFN-γ secretion in the male patients with seborrheic dermatitis significantly increased. The levels of the other studied cytokines did not significantly differ. The treatment with itraconazole had a beneficial effect on the clinical condition of the skin of the patients. IFN-γ is a cytokine whose secretion might affect the condition of the skin in seborrheic dermatitis.

After pilot and preliminary studies aimed at identifying pertinent biochemical parameters, a multicenter clinical study was performed to evaluate the effect of pollution on human skin. The clinical study was performed in collaboration with the 'Centre Régional de lutte contre le cancer de Montpellier' and the 'National Institute of Public Health of Mexico' on 96 subjects in Mexico City (exposed to pollution) and 93 subjects in Cuernavaca (less exposed to pollution). Both biochemical and clinical skin parameters were studied. The study demonstrated significant quantitative and qualitative modifications of parameters related to sebum excretion in Mexico City compared to Cuernavaca one: An increased level of sebum excretion rate, a lower level of vitamin E and squalene in sebum, an increase of lactic acid and a higher erythematous index on the face of the subjects. In the stratum corneum, a significant higher level of carbonylated proteins and a lower level of IL 1α were noticed, as well as a decrease of ATP concentration with a decrease of chymotrysin like activity, without modifications of corneodesmosin content and trypsin like activity. From a clinical point of view, a higher frequency of atopic and urticarial skins, a higher frequency of red dermographism, an important seborrheic status at the forehead level and a lower level of dandruffs were noted in Mexico City population. The analysis taking into account the sex does not modify the observed results. The study demonstrated an important impact of polluted environmental conditions on skin quality, evidencing important modifications of superficial biochemical parameters. The cause/effects relationships of these modifications remain, however, to be further assessed by a complementary in vitro/in vivo approaches. © 2015 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

Cystic Fibrosis (CF) is an autosomal recessive disorder and the incidence of this disease is undermined in Northern India. The distinguishable salty character of the sweat belonging to individuals suffering from CF makes sweat chloride estimation essential for diagnosis of CF disease. The aim of this prospective study was to elucidate the relationship of sweat chloride levels with clinical features and pattern of CF. A total of 182 patients, with clinical features of CF were included in this study for quantitative measurement of sweat chloride. Sweat stimulation and collection involved pilocarpine iontophoresis based on the Gibson and Cooks methodology. The quantitative estimation of chloride was done by Schales and Schales method with some modifications. Cystic Fibrosis Trans Membrane Conductance Regulator (CFTR) mutation status was recorded in case of patients with borderline sweat chloride levels to correlate the results and for follow-up. Out of 182 patients having clinical features consistent with CF, borderline and elevated sweat chloride levels were present in 9 (5%) and 41 (22.5%) subjects respectively. Elevated sweat chloride levels were significantly associated with wheeze, Failure To Thrive (FTT), history of CF in Siblings, product of Consanguineous Marriage (CM), digital clubbing and steatorrhoea on univariate analysis. On multivariate analysis only wheeze, FTT and steatorrhoea were found to be significantly associated with elevated sweat chloride levels (p<0.05). Among the nine borderline cases six cases were positive for at least two CFTR mutations and rest of the three cases were not having any mutation in CFTR gene. The diagnosis is often delayed and the disease is advanced in most patients at the time of diagnosis. Sweat testing is a gold standard for diagnosis of CF patients as genetic mutation profile being heterozygous and unlikely to become diagnostic test.

Background Responding to mandates from the Accreditation Council for Graduate Medical Education (ACGME) and American Osteopathic Association (AOA), residency programs have developed competency-based assessment tools. One such tool is the American College of Osteopathic Pediatricians (ACOP) program directors’ annual report. High-stakes clinical skills licensing examinations, such as the Comprehensive Osteopathic Medical Licensing Examination Level 2-Performance Evaluation (COMLEX-USA Level 2-PE), also assess competency in several clinical domains. Objective The purpose of this study is to investigate the relationships between program director competency ratings of first-year osteopathic residents in pediatrics and COMLEX-USA Level 2-PE scores from 2005 to 2009. Methods The sample included all 94 pediatric first-year residents who took COMLEX-USA Level 2-PE and whose training was reviewed by the ACOP for approval of training between 2005 and 2009. Program director competency ratings and COMLEX-USA Level 2-PE scores (domain and component) were merged and analyzed for relationships. Results Biomedical/biomechanical domain scores were positively correlated with overall program director competency ratings. Humanistic domain scores were not significantly correlated with overall program director competency ratings, but did show moderate correlation with ratings for interpersonal and communication skills. The six ACGME or seven AOA competencies assessed empirically by the ACOP program directors’ annual report could not be recovered by principal component analysis; instead, three factors were identified, accounting for 86% of the variance between competency ratings. Discussion A few significant correlations were noted between COMLEX-USA Level 2-PE scores and program director competency ratings. Exploring relationships between different clinical skills assessments is inherently difficult because of the heterogeneity of tools used and overlap of constructs within the AOA and ACGME core competencies.

Chronic periodontitis is an inflammatory disease of the supporting tissues of the teeth associated with bacteria. Diagnosis is achieved retrospectively by clinical observation of attachment loss. Predicting disease progression would allow for targeted preventive therapy. The aim of this study was to monitor disease progression in patients on a maintenance program and determine the levels of specific bacteria in subgingival plaque samples and then examine the ability of the clinical parameters of disease and levels of specific bacteria in the plaque samples to predict disease progression. During a 12-month longitudinal study of 41 subjects, 25 sites in 21 subjects experienced disease progression indicated by at least 2 mm of clinical attachment loss. Real-time polymerase chain reaction was used to determine the levels of Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, Fusobacterium nucleatum, and Prevotella intermedia in subgingival plaque samples. No clinical parameters were able to predict periodontal disease progression. In sites undergoing imminent periodontal disease progression within the next 3 months, significant partial correlations were found between P. gingivalis and T. forsythia (r = 0.55, P < 0.001) and T. denticola and T. forsythia (r = 0.43, P = 0.04). The odds of a site undergoing imminent periodontal disease progression increased with increasing levels of P. gingivalis and T. denticola. Monitoring the proportions of P. gingivalis and T. denticola in subgingival plaque has the potential to help identify sites at significant risk for progression of periodontitis, which would assist in the targeted treatment of disease.

Anterior cervical decompression and fusion is indicated for patients with anterior compression or stenosis of the spinal cord. The Zero-P spacers have been used for anterior cervical interbody fusion of 1 or 2 segments. However, there is a paucity of published clinical data regarding the exact impact of the device on cervical curvature of 3-level fixation. Clinical and radiologic data of 71 patients undergoing 3-level anterior cervical discectomy and fusion from January 2010 to January 2012 were collected. Zero-P spacer was implanted in 33 patients, and in 38 cases stabilization was accomplished using an anterior cervical plate and intervertebral cage. Patients were followed for a mean of 30.8 months (range, 24-36 mo) after surgery. Fusion rates, changes in cervical lordosis, and degeneration of adjacent segments were analyzed. Dysphagia was assessed using the Bazaz score, and clinical outcomes were analyzed using the Neck Disability Index and Japanese Orthopedic Association scoring system. Neurological outcomes did not differ significantly between groups. Significantly less dysphagia was seen at 2- and 6-month follow-up in patients with the Zero-P implant (P<0.05); however, there was significant less cervical lordosis and the lordosis across the fusion in patients with the Zero-P implant (both P<0.05). Degenerative changes in the adjacent segments occurred in 4 patients in the Zero-P group and 6 patients in the standard-plate group (P=0.742); however, no revision surgery was done. Clinical results for the Zero-P spacer were satisfactory. The device is superior to the traditional plate in preventing postoperative dysphagia; however, it is inferior at restoring cervical lordosis. It may not provide better sagittal cervical alignment reconstruction in 3-level fixation. Prospective randomized trials with more patients and longer follow-up periods are required to confirm these observations.

A prospective cross-sectional study was conducted at 3 government hospitals over 6 months to evaluate the confidence level of medical officers (MOs) to perform clinical procedure in nonspecialist government hospitals in Penang. An anonymous self-administered questionnaire in English was designed based on the elective and emergency procedures stated in the houseman training logbook. The questionnaire was distributed to the MOs from Penang State Health Department through the respective hospital directors and returned to Penang State Health Department on completion. The results showed that there was statistically significant difference between those who had undergone 12 months and 24 months as houseman in performing both elective and emergency procedures. MOs who had spent 24 months as housemen expressed higher confidence level than those who had only 12 months of experience. We also found that the confidence level was statistically and significantly influenced by visiting specialist and working together with cooperative experienced paramedics. © 2013 APJPH.

Adipokines actuate chronic, low-grade inflammation through a complex network of immune markers, but the current understanding of these networks is incomplete. The soluble isoform of the IL-1 receptor accessory protein (sIL1RAP) occupies an important position in the inflammatory pathways involved in obesity. The pathogenetic and clinical influences of sIL1RAP are unknown. The objective of the study was to elucidate whether plasma levels of sIL1RAP are reduced in obesity, using affluent clinical, biochemical, and genetic data from two diverse cohorts. The study was conducted in two cohorts: the San Antonio Family Heart Study (n = 1397 individuals from 42 families) and South Asians living in Mauritius, n = 230). Plasma sIL1RAP levels were measured using an ELISA. The genetic basis of sIL1RAP levels were investigated using both a large-scale gene expression profiling study and a genome-wide association study. A significant decrease in plasma sIL1RAP levels were observed in obese subjects, even after adjustment for age and sex. The sIL1RAP levels demonstrated a strong inverse association with obesity measures in both populations. All associations were more significant in females. Plasma sIL1RAP levels were significantly heritable, correlated with IL1RAP transcript levels (NM_134470), showed evidence for shared genetic influences with obesity measures and were significantly associated with the rs2885373 single-nucleotide polymorphism (P = 6.7 × 10(-23)) within the IL1RAP gene. Plasma sIL1RAP levels are reduced in obesity and can potentially act as biomarkers of obesity. Mechanistic studies are required to understand the exact contribution of sIL1RAP to the pathogenesis of obesity.

The present study aimed to compare the serum level of uric acid in patients with and without heart failure and also to determine the association between uric acid level and clinical status by Killip class in patients with STEMI. This case-control study was conducted on 50 consecutives as control group and 50 patients with acute heart failure, (20 patients had acute STEMI), who documented by both clinical conditions and echocardiography assessment. The mean plasma level of uric acid in the case group was 7.6±1.6 milligrams/deciliter (mg/dL) and in the control group was 4.5±1.5 respectively (P<0.001). These values in patients with STEMI was about 9.2±0.86, but in patients with acute heart failure in absence of STEMI was 6.5±1.04 (P<0.001). Moreover, there was significant difference among the level of uric acid and Killip classes (P<0.001). Also there was significant difference for uric acid level between HFrEF (HF with reduced EF) and severe LV systolic dysfunction (0.049). In STEMI patients with culprit LAD, mean uric acid was significantly higher than cases with culprit LCX [(9.7±0.98 versus 8.6±0.52 respectively) P=0.012]. Regarding  treatment plan in patients with STEMI, mean level of uric acid in those considered for CABG was significantly higher than who were considered for PCI, 9.9±0.82 versus 8.9±0.76 respectively, P=0.029. In STEMI patients with higher killip class, higher level of uric acid was seen. Also, the severity of LV systolic dysfunction was associated with higher level of uric acid.

We previously reported a >50% increase in mean plasma eicosapentaenoic acid levels in a general medicine clinic population after supplementation with alpha-linolenic acid. In the current analysis, we evaluate the variability of changes in eicosapentaenoic acid levels among individuals supplemented with alpha-linolenic acid and evaluated the impact of baseline plasma fatty acids levels on changes in eicosapentaenoic acid levels in these individuals. Changes in eicosapentaenoic acid levels among individuals supplemented with alpha-linolenic acid ranged from a 55% decrease to a 967% increase. Baseline plasma fatty acids had no statistically significant effect on changes in eicosapentaenoic levels acid after alpha-linolenic acid supplementation. Changes in eicosapentaenoic acid levels varied considerably in a general internal medicine clinic population supplemented with alpha-linolenic acid. Factors that may impact changes in plasma eicosapentaenoic acid levels after alpha-linolenic acid supplementation warrant further study.

40 subjects with type 2 diabetes and moderate to severe CP were randomly distributed to groups receiving either NSPT or OHI. Periodontal parameters, glycosylated haemoglobin (HbA1c) and high-sensitivity C-reactive protein (hs-CRP) were evaluated at baseline, 2- and 3-months intervals. 40 subjects with type 2 diabetes and moderate to severe CP were randomly distributed to groups receiving either NSPT or OHI. Periodontal parameters, glycosylated haemoglobin (HbA1c) and high-sensitivity C-reactive protein (hs-CRP) were evaluated at baseline, 2- and 3-months intervals. 15 subjects from NSPT group and 17 from OHI group completed the study. The difference in plaque index (PI) between NSPT and OHI groups were significant at 2 months recall (p = 0.013). There was no significant difference between NSPT and OHI group for all other clinical periodontal parameters, HbA1c and CRP levels. At 3 months post-therapy, periodontal parameters improved significantly in both groups with sites with probing pocket depth (PPD) < 4 mm reported as 98 ± 1.8% in NSPT group and 92 ± 14.9% in OHI group. Mean PPD and mean probing attachment loss (PAL) within the NSPT group reduced significantly from baseline (2.56 ± 0.57 mm, 3.35 ± 0.83 mm) to final visit (1.94 ± 0.26 mm, 2.92 ± 0.72 mm) (p = 0.003, p < 0.001). For OHI group, improvements in mean PPD and mean PAL were also seen from baseline (2.29 ± 0.69 mm, 2.79 ± 0.96 mm) to final visit (2.09 ± 0.72 mm, 2.62 ± 0.97 mm) (p < 0.001 for both). Similarly, HbA1c levels decreased in both groups with NSPT group recording statistically significant reduction (p = 0.038). Participants who demonstrated ≥ 50% reduction in PPD showed significant reductions of HbA1c and hs-CRP levels (p = 0.004 and p = 0.012). NSPT significantly reduced PI at 2 months post-therapy as compared to OHI. Both NSPT and OHI demonstrated improvements in other clinical parameters as well as HbA1c and CRP levels.

To observe the change of the salivary occult blood after periodontal mechanical therapy, and to assess the correlations between salivary occult blood and the level of volatile sulphur compounds (VSC) in oral cavity, periodontal clinical parameters, respectively. Fifty patients with gingivititis, mild or moderate periodontitis were included. The level of VSC were measured by Halimeter(®) and salivary occult blood was tested by Perioscreen(®) before periodontal examination. Then full mouth plaque index (PLI), probing depth (PD), bleeding index (BI) were charted. Attachment loss (AL) of the Ramfjörd teeth were recorded lastly. Intensive periodontal mechanical therapy was conducted including oral hygiene instruction, scaling and root planing (SRP). Four weeks after SRP, the same examinations were repeated. Salivary occult blood was significantly correlated with BI (r = 0.294) and PLI (r = 0.308) before periodontal therapy (P < 0.01), and also significantly correlated with VSC level (r = 0.386), PLI (r = 0.456), BI (r = 0.352), AL (r = 0.325) after therapy (P < 0.05). The improvement of VSC level [211.0 (111.0 - 389.5) × 10⁻⁹ vs 100.0 (46.3 - 165.3) × 10⁻⁹], the clinical periodontal parameters including PLI [(1.3 ± 1.0) vs (0.4 ± 0.6)], PD [(3.7 ± 1.5) mm vs (2.7 ± 0.9) mm], BI [(1.8 ± 1.2) vs (0.4 ± 0.7)] and AL [(1.0 ± 1.1) mm vs (0.1 ± 0.5) mm after the treatment was statistically significant (P < 0.001). However, standing on the viewpoint of salivary occult blood changes from positive before therapy to negative after therapy, only 80% (40/50) individuals were totally cured. VSC level in oral cavity and periodontal clinical parameters significantly decreased (P < 0.001) following the trends from strong positive, weak positive, to negative results of salivary occult blood test. Salivary occult blood was correlated with VSC level in oral cavity of periodontal treated patients. It may be an objective parameter to evaluate the gingival inflammation and the efficacy of the periodontal therapy at individual level.

The aim of the present study was to confirm the effects of a commercially available mung bean protein isolate (GLUCODIA™) on glucose and lipid metabolism. The main component of GLUCODIA™ is 8S globulin, which constitutes 80 % of the total protein. The overall structure of this protein closely resembles soyabean β-conglycinin, which accounts for 20 % of total soya protein (soya protein isolate; SPI). Many physiological beneficial effects of β-conglycinin have been reported. GLUCODIA™ is expected to produce beneficial effects with fewer intakes than SPI. We conducted two independent double-blind, placebo-controlled clinical studies. In the first (preliminary dose decision trial) study, mung bean protein was shown to exert physiological beneficial effects when 3·0 g were ingested per d. In the second (main clinical trial) study, mung bean protein isolate did not lower plasma glucose levels, although the mean insulin level decreased with consumption of mung bean protein. The homeostatic model assessment of insulin resistance (HOMA-IR) values significantly decreased with mung bean protein. The mean TAG level significantly decreased with consumption of mung bean protein isolate. A significant increase in serum adiponectin levels and improvement in liver function enzymes were observed. These findings suggest that GLUCODIA™ could be useful in the prevention of insulin resistance and visceral fat accumulation, which are known to trigger the metabolic syndrome, and in the prevention of liver function decline.

We studied 13 U.S. male military veterans and their female partners who consented to participate in an uncontrolled trial of couple treatment for alcohol use disorder and posttraumatic stress disorder (CTAP). CTAP is a 15-session, manualized therapy, integrating behavioral couples therapy for alcohol use disorder (AUD) with cognitive-behavioral conjoint therapy for posttraumatic stress disorder (PTSD). Due to ineligibility (n = 1) and attrition (n = 3), 9 couples completed the study, and 7 completed 12 or more sessions. There were 8 veterans who showed clinically reliable pre- to posttreatment reduction of PTSD outcomes. There were also significant group-level reductions in clinician-, veteran-, and partner-rated PTSD symptoms (d = 0.94 to 1.71). Most veterans showed clinically reliable reductions in percentage days of heavy drinking. Group-level reduction in veterans' percentage days of heavy drinking was significant (d = 1.01). There were 4 veterans and 3 partners with clinically reliable reductions in depression, and group-level change was significant for veterans (d = 0.93) and partners (d = 1.06). On relationship satisfaction, 3 veterans and 4 partners had reliable improvements, and 2 veterans and 1 partner had reliable deterioration. Group-level findings were nonsignificant for veteran relationship satisfaction (d = 0.26) and for partners (d = 0.52). These findings indicate that CTAP may be a promising intervention for individuals with comorbid PTSD and AUD who have relationship partners.

An atypical subgroup of Social Anxiety Disorder (SAD) with impulsive rather than inhibited traits has recently been reported. The current study examined whether such an atypical subgroup could be identified in a clinical population of 84 adults with SAD. The temperament dimensions harm avoidance and novelty seeking of the Temperament and Character Inventory, and the Liebowitz Social Anxiety Scale were used in cluster analyses. The identified clusters were compared on depressive symptoms, the character dimension self-directedness, and treatment outcome. Among the six identified clusters, 24% of the sample had atypical characteristics, demonstrating mainly generalized SAD in combination with coexisting traits of inhibition and impulsivity. As additional signs of severity, this group showed low self-directedness and high levels of depressive symptoms. We also identified a typically inhibited subgroup comprising generalized SAD with high levels of harm avoidance and low levels of novelty seeking, with a similar clinical severity as the atypical subgroup. Thus, higher levels of harm avoidance and social anxiety in combination with higher or lower levels of novelty seeking and low self-directedness seem to contribute to a more severe clinical picture. Post hoc examination of the treatment outcome in these subgroups showed that only 20 to 30% achieved clinically significant change. © 2014 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

Utilizing serial intravascular ultrasonography (IVUS), we aimed to exam the association of intra-individual lipid variability, coronary atheroma progression, and clinical outcomes. We performed a post hoc patient-level analysis of nine clinical trials involving 4976 patients with coronary artery disease who underwent serial coronary IVUS in the setting of a range of medical therapies. We assessed the associations between progression in percent atheroma volume (ΔPAV), clinical outcomes, and visit-to-visit lipid variability including low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-HDL-C, total cholesterol (TC)/HDL-C, and apolipoprotein B (ApoB). Variability of lipid parameters was measured using intra-individual standard deviation over 3, 6, 12, 18, and 24 months. Atherogenic lipoprotein variability significantly associated with ΔPAV [odds ratio (95% confidence interval; P-value), LDL-C: 1.09 (1.02, 1.17, P = 0.01); non-HDL-C: 1.10 (1.02, 1.18, P = 0.01); TC/HDL-C: 1.14 (1.06, 1.24, P = 0.001); ApoB: 1.13 (1.03, 1.24, P = 0.01)]. Survival curves revealed significant stepwise relationships between cumulative major adverse cardiovascular events and increasing quartiles of atherogenic lipoprotein variability at 24-months follow-up (log-rank P < 0.01 for all lipoproteins except HDL-C). Stronger associations were noted between achieved lipoprotein levels and ΔPAV [LDL-C: 1.27 (1.17, 1.39; P < 0.001); non-HDL-C: 1.32 (1.21, 1.45; P < 0.001); TC/HDL-C: 1.31 (1.19, 1.45; P < 0.001); ApoB: 1.20 (1.07, 1.35; P = 0.003)]. Greater visit-to-visit variability in atherogenic lipoprotein levels significantly associates with coronary atheroma progression and clinical outcomes, although the association between achieved atherogenic lipoproteins and atheroma progression appears stronger. These data highlight the importance of achieving low and consistent atherogenic lipoprotein levels to promote plaque regression and improve clinical outcomes.

Organisational quality, nurse staffing and the quality of chronic disease management in primary care: observational study using routinely collected data.

An association between quality of care and staffing levels, particularly registered nurses, has been established in acute hospitals. Recently an association between nurse staffing and quality of care for several chronic conditions has also been demonstrated for primary care in English general practice. A smaller body of literature identifies organisational factors, in particular issues of human resource management, as being a dominant factor. However the literature has tended to consider staffing and organisational factors separately. We aim to determine whether relationships between the quality of clinical care and nurse staffing in general practice are attenuated or enhanced when organisational factors associated with quality of care are considered. We further aim to determine the relative contribution and interaction between these factors. We used routinely collected data from 8409 English general practices. The data, on organisational factors and the quality of clinical care for a range of long term conditions, is gathered as part of "Quality and Outcomes Framework" pay for performance system. Regression models exploring the relationship of staffing and organisational factors with care quality were fitted using MPLUS statistical modelling software. Higher levels of nurse staffing, clinical recording, education and reflection on the results of patient surveys were significantly associated with improved clinical care for COPD, CHD, Diabetes and Hypothyroidism after controlling for organisational factors. There was some evidence of attenuation of the estimated nurse staffing effect when organisational factors were considered, but this was small. The effect of staffing interacted significantly with the effect of organisational factors. Overall however, the characteristics that emerged as the strongest predictors of quality of clinical care were not staffing levels but the organisational factors of clinical recording, education and training and use of patient experience surveys. Organisational factors contribute significantly to observed variation in the quality of care in English general practices. Levels of nurse staffing have an independent association with quality but also interact with organisational factors. The observed relationships are not necessarily causal but a causal relationship is plausible. The benefits and importance of education, training and personal development of nursing and other practice staff was clearly indicated. Copyright © 2011. Published by Elsevier Ltd.

HsCRP (Highly sensitive C reactive protein) is a global indicator for future vascular events in adults detected in blood stream 48 hours before the cardiovascular event. Periodontal disease may increase blood levels of inflammatory markers like IL-6, CRP and HsCRP. Hence the aim of the present study is to evaluate the presence of elevated HsCRP levels in chronic periodontitis patients. 100 patients who reported for cardiac master health check up were enrolled in the study. The periodontal status was assessed using periodontal probing pocket depth and clinical attachment level. The decayed, missing and filled tooth was recorded using DMFT index. The venous samples of these patients were obtained for recording HsCRP levels. Pearson correlation was used to analyze the relationship between HsCRP level and probing pocket depth, clinical attachment loss and DMFT. The correlation value was 0.051, 0.025 and 0.101 respectively, the correlation is statistically significant for probing pocket depth and clinical attachment level (P>0.05). Chi-square test was performed to study the association between gender and HsCRP, Diabetes Mellitus and HsCRP and Hypertension and HsCRP; the results showed that there is no significant association between any of the above mentioned factors and HsCRP level in blood. We found an increased level of HsCRP in patients with chronic periodontitis which revealed the susceptibility of these patients to cardiac diseases like myocardial infarction and stroke. Hence present day focus in the line of management of cardiac patient has changed from the periodontal perspective.

Objective: To investigate the expression and clinical significance of nuclear factor (erythroid-derived 2)-like 2 (Nrf2) and Kelch-like ECH-associated protein 1 (Keap1) in osteosarcoma tissue. Methods: The data of 102 osteosarcoma patients who underwent surgical treatment at our hospital from June 2000 to March 2009 were collected. The expression levels of the Nrf2 and Keap1 proteins in osteosarcoma tissue and normal peritumour tissues were detected by immunohistochemistry, and the relationship between the expression level and the clinical and pathological features as well as the prognosis was explored. Results: The nuclear expression rate of Nrf2 was 77.5% in osteosarcoma tissue, which wasmore » significantly higher than the rate in normal peritumour bone tissue (9.8%) (P < 0.05). The expression rate of the Keap1 protein in osteosarcoma tissue was 13.7%, which was significantly lower than the rate in normal peritumour tissue (80.4%). In addition, Nrf2/Keap1 expression was unrelated to patient gender and age, tumour site, and histological type and was related to metastasis and patient response to chemotherapy (P < 0.05). The five-year survival rate was significantly lower in patients with positive Nrf2 expression than in those with negative Nrf2 expression (p = 0.023), and it was significantly higher in patients with positive Keap1 expression than in those with negative Keap1 expression (P = 0.018). Conclusion: The expression of Nrf2-Keap1 is abnormal in osteosarcoma tissue and shows significant clinical relevance for determining the prognosis of osteosarcoma.« less

Threshold level or not for low-density lipoprotein cholesterol.

PubMed

Barter, P J; Sacks, F M

2001-05-01

As drugs, such as the statins, and other therapies demonstrate the ability to significantly lower levels of low-density lipoprotein cholesterol (LDL-C), one issue is whether there is a lower threshold below which no further decline in coronary heart disease occurs. Those who evaluate the data from multiple trials and conclude that no significant decrease in coronary event rates occurs at or below 125 mg/dL suggest using this level as a guideline for clinical application of cholesterol-lowering therapy. On the other hand, analysis of the results of the same population and primary prevention studies concludes that no such threshold exists. The issues affected by the decision of whether to use a threshold include costs to the healthcare system for additional physician time, tests, and medication; unknown clinical events and safety related to very low LDL-C; and resource prioritization to an unestablished therapeutic approach.

Our aim is to evaluate the validity of exhaled carbon monoxide (CO) and of a newly-created score as markers of Chronic Obstructive Pulmonary Disease (COPD). The CO level was measured in a derivation subsample of a cross-sectional study and linked to COPD diagnosis; its predictors were evaluated, and a scale was constructed. It was evaluated in a validation subsample and in a clinical setting. Individuals with COPD had higher CO levels than healthy individuals. CO level significant predictors were cigarettes per day, waterpipes per week, lower age, male gender, living close to diesel exhaust, heating home with the use of diesel, and having indoor family smokers. A score composed of CO predictors was able to significantly predict COPD (Ora = 4-7.5). Coupled with the clinical judgment of physicians, this scale would be an excellent low-cost tool for screening COPD, in absence of spirometry.

This study explores the relationship between clinical cardiovascular risk factors and clinical androgen excess, with direct comparison to radial artery intima media thickness (rIMT). rIMT of 91 patients with polycystic ovary syndrome (PCOS) were compared with 72 healthy women. Patients were divided into three groups with regard to body mass index (BMI). Group1 = 56 women (31 controls and 25 PCOS) with low BMI(18-22.49 kg/m(2)), Group2 = 36 women (15 controls and 21 PCOS) with normal BMI (22.5-24.99 kg/m(2)) and Group3 = 71 women (26 controls and 45 PCOS) with high BMI (25-30 kg/m(2)). rIMT was significantly higher in patients with PCOS (p = 0.007). rIMT was significantly higher group1 and group3 in patients with PCOS compared to controls (p = 0.007 and p = 0.042, respectively). There was a significant positive association between rIMT levels and fT in women with PCOS in group1 (r = 0.24, p = 0.04). rIMT levels correlated to fT levels in women with PCOS in group3 (r = 0.32, p = 0.03). Modified Ferriman-Gallwey (mFG) scores demonstrated a positive association with free testosterone, total testosterone, free androgen index, waist circumference (WC), LH levels, insulin levels, Homeostasis Model Assessment index(HOMA-IR), rIMT and a negative correlation with sex hormone binding globulin in group1 and group2. mFG scores demonstrated a positive association with free testosterone (r = 0.33, p = 0.029) in group3, but no association was found between mFG and WC, HOMA-IR in group3. Our findings indicate that clinical androgen excess may be associated with cardiovascular disease in patients with PCOS.

Study Objectives: Other than hypocretin-1 (HCRT-1) deficiency in narcolepsy type 1 (NT1), the neurochemical imbalance of NT1 and narcolepsy type 2 (NT2) with normal HCRT-1 levels is largely unknown. The neuropeptide melanin-concentrating hormone (MCH) is mainly secreted during sleep and is involved in rapid eye movement (REM) and non-rapid eye movement (NREM) sleep regulation. Hypocretin neurons reciprocally interact with MCH neurons. We hypothesized that altered MCH secretion contributes to the symptoms and sleep abnormalities of narcolepsy and that this is reflected in morning cerebrospinal fluid (CSF) MCH levels, in contrast to previously reported normal evening/afternoon levels. Methods: Lumbar CSF and plasma were collected from 07:00 to 10:00 from 57 patients with narcolepsy (subtypes: 47 NT1; 10 NT2) diagnosed according to International Classification of Sleep Disorders, Third Edition (ICSD-3) and 20 healthy controls. HCRT-1 and MCH levels were quantified by radioimmunoassay and correlated with clinical symptoms, polysomnography (PSG), and Multiple Sleep Latency Test (MSLT) parameters. Results: CSF and plasma MCH levels were not significantly different between narcolepsy patients regardless of ICSD-3 subtype, HCRT-1 levels, or compared to controls. CSF MCH and HCRT-1 levels were not significantly correlated. Multivariate regression models of CSF MCH levels, age, sex, and body mass index predicting clinical, PSG, and MSLT parameters did not reveal any significant associations to CSF MCH levels. Conclusions: Our study shows that MCH levels in CSF collected in the morning are normal in narcolepsy and not associated with the clinical symptoms, REM sleep abnormalities, nor number of muscle movements during REM or NREM sleep of the patients. We conclude that morning lumbar CSF MCH measurement is not an informative diagnostic marker for narcolepsy. Citation: Schrölkamp M, Jennum PJ, Gammeltoft S, Holm A, Kornum BR, Knudsen S.

This study aims to evaluate the effect of one-stage full-mouth ultrasonic debridement (OSFMUD) on clinical and immunoinflammatory parameters in smokers with generalized aggressive periodontitis (GAgP). Fourteen smoking and 14 non-smoking patients with GAgP were selected. After initial supragingival therapy, patients were treated by OSFMUD. Full-mouth parameters evaluated were: 1) plaque index (PI); 2) bleeding scores (BS); 3) probing depth (PD); and 4) clinical attachment level (CAL). Clinical evaluation was performed, and gingival crevicular fluid (GCF) was collected for selected sites (ss) at baseline and 1, 3, and 6 months. GCF was analyzed via enzyme-linked immunosorbent assay for: 1) receptor activator of nuclear factor-κ B ligand (RANKL); 2) osteoprotegerin (OPG); 3) interleukin (IL)-6; and 4) tumor necrosis factor (TNF)-α, whereas secreted osteoclastogenic factor of activated T-cells (SOFAT) was evaluated by Western blotting. Significant reduction (P <0.05) was observed between baseline and 6 months for: 1) PI; 2) BS; and 3) PD, with no difference between smoking and non-smoking patients (P >0.05). Regarding CAL, only non-smoking patients showed a significant decrease (P <0.05). Significant reduction (P <0.05) was observed in both groups for: 1) PIss; 2) PDss; 3) bleeding on probing; and 4) relative CAL. Smoking and non-smoking patients presented significantly decreased levels of IL-6 and TNF-α over time (P <0.05); however, no difference was observed between groups (P >0.05). RANKL was significantly different (P <0.05) only for non-smokers at 6 months, whereas OPG was not significant (P >0.05). SOFAT expression was significantly lower (P <0.05) after OSFMUD for non-smokers only. Considering the clinical and immunoinflammatory parameters evaluated in this short-term follow-up study, it can be concluded that OSFMUD can be used as an alternative treatment for smokers with GAgP.

Vitamin D3 might benefit prostate cancer (PCa) patients because prostate cells can locally synthesize the active hormone calcitriol. Our objective was to determine the effects of oral vitamin D3 on vitamin D metabolites and PCa proliferative activity in prostate tissue. We conducted a double-blind randomized clinical trial at surgical oncology clinics in Toronto, Canada. PCa patients (Gleason 6 or 7) participated in the study. Of 66 subjects who were enrolled, 63 completed the dosing protocol. Vitamin D3 (400, 10000, or 40000 IU/d) was orally administered before radical prostatectomy. We evaluated vitamin D metabolite levels and Ki67 labeling in surgical prostate tissue. Safety measures, PTH, and prostate-specific antigen (PSA) were also assessed. Prostate tissue and serum levels of vitamin D metabolites, including calcitriol, increased dose dependently (P<.03) and were significantly higher in the 40000-IU/d group than in every other dose group (P<.03). Prostate vitamin D metabolites correlated positively with serum levels (P<.0001). Ki67 measures did not differ significantly among vitamin D dose groups. However, cross-sectional analysis indicated that the calcitriol level attained in prostate was inversely associated with Ki67 intensity and Ki67 (3+) percent positive nuclei in PCa and benign tissue (P<.05). Safety measures did not change adversely with dosing. Compared with the 400-IU/d group, serum PTH and PSA were lower in the combined higher-dose groups at the end of the study (P< .02). Oral vitamin D3 raised prostate calcitriol levels (level 1 evidence) and modestly lowered both PSA and PTH. Although Ki67 expression did not differ among dose groups, its levels correlated inversely with prostate calcitriol. These suggestions of clinical benefit justify continued clinical research.

Clinical growth is an essential component of nursing education, although challenging to evaluate. Considering the paradigm shift toward constructivism and student-centered learning, clinical growth requires an examination within contemporary practices. A concept analysis of clinical growth in nursing education produced defining attributes, antecedents, and consequences. Attributes included higher-level thinking, socialization, skill development, self-reflection, self-investment, interpersonal communication, and linking theory to practice. Identification of critical attributes allows educators to adapt to student-centered learning in the clinical environment. These findings allow educators to determine significant research questions, develop situation-specific theories, and identify strategies to enhance student learning in the clinical environment.

To investigate the relationship between fasting insulin levels and metabolic risk factors (MRFs) in type 2 diabetic patients at the first clinic/hospital visit in Japan over the years 2000 to 2009. In total, 4,798 drug-naive Japanese patients with type 2 diabetes were registered on their first clinic/hospital visits. Conventional clinical factors and fasting insulin levels were observed at baseline within the Japan Diabetes Clinical Data Management (JDDM) study between consecutive 2-year groups. Multiple linear regression analysis was performed using a model in which the dependent variable was fasting insulin values using various clinical explanatory variables. Fasting insulin levels were found to be decreasing from 2000 to 2009. Multiple linear regression analysis with the fasting insulin levels as the dependent variable showed that waist circumference (WC), BMI, mean blood pressure, triglycerides, and HDL cholesterol were significant, with WC and BMI as the main factors. ANCOVA after adjustment for age and fasting plasma glucose clearly shows the decreasing trend in fasting insulin levels and the increasing trend in BMI. During the 10-year observation period, the decreasing trend in fasting insulin was related to the slight increase in WC/BMI in type 2 diabetes. Low pancreatic β-cell reserve on top of a lifestyle background might be dependent on an increase in MRFs.

Patients with liver cirrhosis often exhibit zinc deficiency. Although zinc is involved in many bioactivities, many aspects of clinical implications of zinc deficiency in liver cirrhosis remain unclear. We aimed to reveal the prevalence and implications of zinc deficiency in liver cirrhosis by assessing associations with parameters such as clinical symptoms and laboratory data. In 235 cirrhosis patients enrolled at multiple medical institutions in 2009, we assessed how blood zinc levels were associated with their clinical symptoms, patients characteristics, and liver function test results. Blood zinc levels were most strongly correlated with blood albumin levels among the study parameters (r = 0.587, P < 0.0001). When blood albumin levels were ≤ 3.5 g/dL, blood zinc levels were < 70 μg/dL in 88% of patients. Additionally, significant correlations were observed with age (r = -0.253, P = 0.0014), aspartate aminotransferase levels (r = -0.254, P = 0.0020), total bilirubin levels (r = -0.222, P = 0.0053), prothrombin time (r = -0.255, P = 0.0029), branched-chain amino acid to tyrosine ratio (r = 0.357, P < 0.0001), Child-Pugh score (r = 0.469, P < 0.0001), ammonia levels (r = -0.246, P = 0.0028), and total cholesterol levels (r = 0.314, P < 0.0001). Blood zinc levels were significantly lower in patients with edema/ascites (P < 0.0001), those with hepatic encephalopathy (P = 0.0215), those receiving oral diuretics (P = 0.0045), and those receiving oral branched-chain amino acids (P < 0.0001) than in those without these conditions. Zinc deficiency is prevalent in cirrhosis patients, whereas nitrogen metabolic disorders, particularly hypoalbuminemia, can be an indicator of zinc deficiency. Thus, cirrhosis patients exhibiting a nitrogen metabolic disorder should be examined for the presence of zinc deficiency.

To assess the efficacy of a pharmacist-led, primary care-based, disease management program to improve cardiovascular risk factors and glycated hemoglobin (A(1C)) levels in vulnerable patients with poorly controlled diabetes. A randomized controlled trial of 217 patients with type 2 diabetes and poor glycemic control (A(1C) level >or=8.0%) was conducted at an academic general medicine practice from February 2001 to April 2003. Intervention patients received intensive management from clinical pharmacists, as well as from a diabetes care coordinator who provided diabetes education, applied algorithms for managing glucose control and decreasing cardiovascular risk factors, and addressed barriers to care. Control patients received a one-time management session from a pharmacist followed by usual care from their primary care provider. Outcomes were recorded at baseline and at 6 and 12 months. Primary outcomes included blood pressure, A(1C) level, cholesterol level, and aspirin use. Secondary outcomes included diabetes knowledge, satisfaction, use of clinical services, and adverse events. For the 194 patients (89%) with 12-month data, the intervention group had significantly greater improvement than did the control group for systolic blood pressure (-9 mm Hg; 95% confidence interval [CI]: -16 to -3 mm Hg) and A(1C) level (-0.8%; 95% CI: -1.7% to 0%). Change in total cholesterol level was not significant. At 12 months, aspirin use was 91% in the intervention group versus 58% among controls (P <0.0001). Intervention patients had greater improvements in diabetes knowledge and satisfaction than did control patients. There were no significant differences in use of clinical services or adverse events. Our comprehensive disease management program reduced cardiovascular risk factors and A(1C) levels among vulnerable patients with type 2 diabetes and poor glycemic control.

Dynamics of Heat Shock Protein 70 Serum Levels As a Predictor of Clinical Response in Non-Small-Cell Lung Cancer and Correlation with the Hypoxia-Related Marker Osteopontin

Hypoxia mediates resistance to radio(chemo)therapy (RT) by stimulating the synthesis of hypoxia-related genes, such as osteopontin (OPN) and stress proteins, including the major stress-inducible heat shock protein 70 (Hsp70). Apart from its intracellular localization, Hsp70 is also present on the plasma membrane of viable tumor cells that actively release it in lipid vesicles with biophysical characteristics of exosomes. Exosomal Hsp70 contributes to radioresistance while Hsp70 derived from dying tumor cells can serve as a stimulator of immune cells. Given these opposing traits of extracellular Hsp70 and the unsatisfactory outcome of locally advanced lung tumors, we investigated the role of Hsp70 in the plasma of patients with advanced, non-metastasized non-small-cell lung cancer (NSCLC) before (T1) and 4–6 weeks after RT (T2) in relation to OPN as potential biomarkers for clinical response. Plasma levels of Hsp70 correlate with those of OPN at T1, and high OPN levels are significantly associated with a decreased overall survival (OS). Due to a therapy-induced reduction in viable tumor mass after RT Hsp70 plasma levels dropped significantly at T2 (p = 0.016). However, with respect to the immunostimulatory capacity of Hsp70 derived from dying tumor cells, patients with higher post-therapeutic Hsp70 levels showed a significantly better response to RT (p = 0.034) than those with lower levels at T2. In summary, high OPN plasma levels at T1 are indicative for poor OS, whereas elevated post-therapeutic Hsp70 plasma levels together with a drop of Hsp70 between T1 and T2, successfully predict favorable responses to RT. Monitoring the dynamics of Hsp70 in NSCLC patients before and after RT can provide additional predictive information for clinical outcome and therefore might allow a more rapid therapy adaptation.

Colorectal anastomotic leakage is a serious complication leading to major postoperative morbidity and mortality. In the present study, we investigated the early detection of anastomotic leakage before its clinical presentation. Fifty-six patients with rectal cancer were included prospectively in this study. All patients underwent elective low anterior resection. Peritoneal samples were collected from the abdominal drains at the first, third, and fifth days postoperatively for bacteriological study (quantitative cultures for both aerobes and anaerobes) and cytokines (IL-6, IL-10, TNF) measurement. Patients were divided into two groups: those without symptomatic or clinical evidence of anastomotic leakage (AL; group 1) and those with clinical evidence of AL (group 2). Study variables included hospital stay, wound infection, operative time, blood loss, height of anastomosis, intraperitoneal cytokines, and microbiological study of peritoneal fluid. Clinically evident AL occurred in eight patients (14.3%) and diagnosed postoperatively on median day 6. Intraperitoneal bacterial colonization and cytokine levels were significantly higher in patients with clinical evidence of AL. Wound infection was significantly higher in anastomotic leakage group. The hospital stay for the patients with anastomotic leakage was significantly longer than those without AL (14 ± 1.41 vs. 5.43 ± 0.89 days). A significant difference among two groups was observed regarding operative time, blood loss, blood transfusion, and height of the anastomosis. The peritoneal cytokines levels and intraperitoneal bacterial colonization might be an additional diagnostic tool that can support the decision making of surgeons for early detection of anastomotic leak in colorectal surgery.

This study employed a commercially available, non-invasive, fluorescence imaging system (Dyaderm, Biocam, Germany), to measure protoporphyrin IX (PpIX) concentration at several different stages during clinical dermatological methyl aminolevulinate photodynamic therapy (MAL-PDT). We validated the system prior to use to ensure that the PpIX changes witnessed were accurate and not due to environmental or user induced artifacts. The system was then employed to acquire color (morphological) and fluorescent (physiological) images simultaneously during dermatological PDT. Clinical data was collected from a range of licensed dermatological conditions (actinic keratosis, Bowen's disease and superficial basal cell carcinoma) during initial and subsequent PDT treatment cycles. The initial clinical data indicated that each type of licensed lesion considered responded in a similar manner following the application of Metvix (Galderma, U.K.) and the subsequent light irradiation (Aktilite, Galderma, U.K.). Images acquired three hours after Metvix application showed a significant increase in PpIX concentration within the lesion (P < 0.05), whilst PpIX levels in the surrounding normal tissue remained unaltered. After irradiation, the PpIX concentration was significantly decreased and returned to a level similar to the initial concentration originally observed. Lesions that received subsequent treatment cycles accumulated significantly less PpIX (P < 0.05) prior to irradiation.

To evaluate the impact of two baccalaureate public health nursing (PHN) clinical education models, that vary on level of engagement with community agencies, on student perceptions of PHN. Two group, pretest/posttest design. Two cohorts of baccalaureate nursing students (traditional n = 62, accelerated n = 64) were included. The traditional students worked with one agency over an 8-week period. The accelerated students worked with several agencies over the same period. Eighty-seven students provided complete data at both time points, and were included in analyses. Students answered questions at the beginning and end of the Spring 2014 semester to assess knowledge, confidence, satisfaction, and career intention related to PHN. At baseline, traditional students reported significantly higher confidence working independently and less intention to choose PHN as a career. Both cohorts reported a significant increase in knowledge and independence from pretest to posttest. At posttest, the accelerated group showed a significant decline in likelihood of choosing a PHN career. In developing PHN clinical curriculum, careful consideration should be given to the level of engagement with the community and faculty. Future work should continue exploring different PHN clinical education models to ensure students are effectively prepared in this area of nursing. © 2016 Wiley Periodicals, Inc.

Omega-3 polyunsaturated fatty acids (PUFAs) have been proven critical in the development and management of major depressive disorder (MDD) by a number of epidemiological, clinical and preclinical studies, but the molecular mechanisms underlying this therapeutic action are yet to be understood. Although eicosapentaenoic acid (EPA) seems to be the active component of omega-3 PUFAs' antidepressant effects, the biological research about the difference of specific genetic regulations between EPA and docosahexaenoic acid (DHA), the two main components of omega-3 PUFAs, is still lacking in human subjects. We conducted a 12-week randomized-controlled trial comparing the effects of EPA and DHA on gene expressions of phospholipase A2 (cPLA2) and cyclooxygenase-2 (COX2), serotonin transporter (5HTT), and Tryptophan hydroxylase 2 (TPH-2) in 27 MDD patients. In addition, the erythrocyte PUFA compositions and the candidate gene expressions were also compared between these 27 MDD patients and 22 healthy controls. EPA was associated with a significant decrease in HAM-D scores (CI: -13 to -21, p<0.001) and significant increases in erythrocyte levels of EPA (CI: +1.0% to +2.9%, p=0.001) and DHA (CI: +2.9% to +5.6%, p=0.007). DHA treatment was associated with a significant decrease in HAM-D scores (CI: -6 to -14, p<0.001) and a significant increase in DHA levels (CI: +0.2% to +2.3%, p=0.047), but not of EPA levels. The cPLA2 gene expression levels were significantly increased in patients received EPA (1.9 folds, p=0.038), but not DHA (1.08 folds, p=0.92). There was a tendency for both EPA and DHA groups to decrease COX-2 gene expressions. The gene expressions of COX-2, cPLA2, TPH-2 and 5-HTT did not differ between MDD cases and healthy controls. EPA differentiates from DHA in clinical antidepressant efficacy and in upregulating cPLA2 gene regulations, which supports the clinical observation showing the superiority of EPA's antidepressant effects.

To explore the expression of Rictor and mTOR in the colorectal cancer and their clinical significance. The expression levels of Rictor and mTOR in HCT116, SW480, LoVo and HCoEpiC cells were detected by indirect immunofluorescence and Western blotting. Sixty-two paraffin-embedded surgical specimens of colorectal cancer tissue and adjacent tissues were examined for Rictor expression using immunohistochemistry. The association of the expression levels of Rictor protein with the clinicopathologic features and the overall survival of the patients was analyzed. The expression level of Rictor was significantly higher in colorectal cancer tissues than in the adjacent tissues (P<0.05). The expression levels of Rictor and mTOR in the colon cancer cell lines were higher than those in human normal colon epithelial cell line HCoEpiC. The expression of Rictor was correlated with Dukes stage and lymphatic metastasis of the tumors but not with other clinicopathological parameter (P>0.05). Patients with Rictor expression had a lower overall survival rate than those without Rictor expression. Rictor overexpression is associated with the carcinogenesis and progression of colorectal cancer and can be an independent indicator for evaluating the prognosis of colorectal cancer patients.

Objective. The current study attempted to identify and characterize distinct CP subgroups based on their level of dispositional personality traits. The secondary objective was to compare the difference among the subgroups in mood, coping, and disability. Methods. Individuals with chronic pain were assessed for demographic, psychosocial, and personality measures. A two-step cluster analysis was conducted in order to identify distinct subgroups of patients based on their level of personality traits. Differences in clinical outcomes were compared using the multivariate analysis of variance based on cluster membership. Results. In 229 participants, three clusters were formed. No significant difference was seen among the clusters on patient demographic factors including age, sex, relationship status, duration of pain, and pain intensity. Those with high levels of dispositional personality traits had greater levels of mood impairment compared to the other two groups (p < 0.05). Significant difference in disability was seen between the subgroups. Conclusions. The study identified a high risk group of CP individuals whose level of personality traits significantly correlated with impaired mood and coping. Use of pharmacological treatment alone may not be successful in improving clinical outcomes among these individuals. Instead, a more comprehensive treatment involving psychological treatments may be important in managing the personality traits that interfere with recovery.

Abstract Objective: This study evaluated the expression of pro-inflammatory (IL-1β, IL-6, IFN-γ and TNF-α) and anti-inflammatory (IL-4 and TGF-β) cytokines in apical periodontitis lesions. Correlations between these cytokines and clinical and cone-beam computed tomographic (CBCT) data were also assessed. Material and Methods: Apical periodontitis lesions’ data were obtained from 27 patients subjected to periradicular surgery. Specimens were processed for histopathologic and immunohistochemical analysis. Sections were evaluated according to the amount of positive staining for each antibody. Expression levels of the target mediators were compared with clinical and CBCT data. Results: Twenty lesions were diagnosed as granuloma and 7 as cyst. In granulomas, IL-4 expression was significantly higher than IL-6 (p=0.001) and TNF-α (p=0.001). There was a significant relationship between high levels of TNF-α and lesions <5 mm (p=0.017). In cysts, IL-6 expression was significant lower than IL-4 (p=0.001) and IFN-γ (p=0.004). There was a significant relationship between high levels of TGF-β and endodontic treatment performed ≤4 years before (p=0.045). In general, IL-4 was the most expressed mediator in both cysts and granulomas. Conclusions: There was a balance between the expression of pro-inflammatory and anti-inflammatory cytokines associated with the chronic periradicular inflammatory process. TNF-α and TGF-β were related to some clinical and CBCT data. PMID:29898177

Periodontitis is a chronic bacterial infection characterized by persistent inflammation, connective tissue breakdown and alveolar bone destruction mediated by pro-inflammatory mediators. Tumor necrosis factor-alpha (TNF-α) is an important pro-inflammatory mediator that produced causes destruction of periodontal tissues. The aim of the study is to estimate the salivary TNF-α in chronic and aggressive periodontitis and control participants and further correlate the levels with clinical parameter such as gingival index (GI), plaque index (PI), probing pocket depth (PPD) and clinical attachment loss. The study population consisted of 75 subjects age ranging from 25 to 55 years attending the outpatient section of Department of Periodontics, Saveetha Dental College and Hospital. The study groups included Groups 1, 2, and 3 with participants with healthy periodontium (n = 25), generalized chronic periodontitis (n = 25) and generalized aggressive periodontitis (n = 25), respectively. Salivary samples from the participants were used to assess the TNF-α levels using enzyme-linked immunosorbent assay. GI and PI were found to be significantly higher in chronic and aggressive periodontitis compared to the controls. The mean TNF-α value in chronic periodontitis patients (12.92 ± 17.21 pg/ml) was significantly higher than in control subjects (2.15 ± 3.60 pg/ml). Whereas, in aggressive periodontitis patients the mean TNF-α (7.23 ± 7.67) were not significantly different from chronic periodontitis or healthy subjects. Among periodontitis participants, aggressive periodontitis subjects exhibited a significant positive correlation between the salivary TNF-α and PPD. Salivary TNF-α levels are significantly higher in chronic periodontitis than in healthy subjects, but there was no significant correlation with the clinical parameters.

To determine clinical/neurophysiological characteristics of different forms of attention deficit hyperactivity disorder (ADHD) and the efficacy of treatment with cerebrolysin. Sixty children, aged 9 to 12 years, with ADHD were examined using clinical and electroencephalographic methods. Idiopathic and residual-organic forms were compared. The study shows significantly higher levels of impulsivity and hyperactivity in children with residual-organic form of the disease. There were significant differences in the amplitude component of engaging in action (P3 Go) and the amplitude of the action suppression component (P3 NOGO) in patients with different forms of ADHD. The high clinical efficacy (improvement in 70.0% of patients with idiopathic form of ADHD and 86.7% of patients with residual-organic form of the disease) was found.

Clinical nursing expertise is central to quality patient care. Research on factors that contribute to expertise has focused largely on individual nurse characteristics to the exclusion of contextual factors. To address this, we examined effects of hospital contextual factors and individual nurse education and experience on clinical nursing expertise in a cross-sectional analysis of data from 8,611 registered nurses. In a generalized ordered logistic regression analysis, the composition of the hospital staff, particularly the proportion of nurses with at least a bachelor of science in nursing degree, was associated with significantly greater odds of a nurse reporting a more advanced expertise level. Our findings suggest that, controlling for individual characteristics, the hospital context significantly influences clinical nursing expertise. PMID:20645420

Catecholamines, brain-derived neurotrophic factor (BDNF) and cytokines may be involved in the pathophysiology of schizophrenia. The aim of this study was to examine the associations between serum BDNF levels, plasma catecholamine metablolites, cytokines and the cognitive functions of patients with schizophrenia treated with atypical antipsychotic monotherapy. One hundred and forty-six patients with schizophrenia and 51 age- and sex-matched healthy controls were examined for peripheral biological markers and neurocognitive test. There were positive correlations between serum BDNF levels and scores for verbal memory and attention and processing speed as well as between serum BDNF levels and negative symptoms. Furthermore, there was a negative correlation between the plasma homovanillic acid (HVA) level and motor function and a positive correlation between the plasma 3-methoxy-4-hydroxyphenylglycol (MHPG) level and attention and processing speed. There were no significant correlations between interleukin-6 or tumour necrosis factor alpha and cognitive function. Moreover, there were no significant correlations between the plasma levels of HVA, MHPG, cytokines and clinical symptoms. Serum BDNF levels are positively related to the impairment of verbal memory and attention, plasma HVA levels are positively related to motor function, and plasma MHPG levels are positively related to attention in patients with schizophrenia.

BACKGROUND Levels of pro-inflammatory cytokine (IL-1β) released by peripheral blood leukocyte medium (PBLM), isolated from chronic periodontitis patients (P) before therapy and matched to controls, were determined in the presence or absence of non-opsonized Escherichia coli and Staphylococcus aureus. MATERIAL AND METHODS In this investigation, 26 patients with untreated, severe, generalized, chronic periodontitis and 26 healthy subjects (H) were enrolled. Periodontal status was assessed by measuring bleeding on probing (BOP), clinical attachment loss (CAL), probing pocket depth (PPD), and Ramfjord index (PDI). The levels of IL-1β (µg/ml) were assayed by a standard Immunoenzymetric Assay Diasource IL-1β ELISA kit in PBLM. RESULTS Our study showed that the values of IL-1β levels in PBLM of the P group (stimulated with non-opsonized E. coli and S. aureus) were significantly higher than in the analogous medium of H group subjects (P<0.001). All correlations between the cytokine levels of IL-1β in the samples of PBLM (stimulated with non-opsonized E. coli and S. aureus) and clinical parameters such as BOP, PPD, CAL, and PDI were significantly higher in the group of patients with periodontitis. CONCLUSIONS Levels of IL-1β secreted by leukocytes may help measure severe, generalized, chronic periodontitis, and can be predictive of future detrimental clinical sequelae associated with chronic periodontitis.

Effects of cholinesterase inhibitors on the activities and protein levels of cholinesterases in the cerebrospinal fluid of patients with Alzheimer's disease: a review of recent clinical studies.

Alzheimer's disease (AD) is a progressive neurodegenerative disease characterized by cognitive decline associated with a deficit in cholinergic function. Inhibitors of acetylcholinesterase (AChE) and/or butyrylcholinesterase (BuChE), such as donepezil, galantamine or rivastigmine, are widely prescribed as symptomatic treatments for AD. These agents exhibit a wide variation in their pharmacological properties. Here we review clinical data from 1998 to 2009 investigating the effect of different cholinesterase inhibitor treatments on the levels and activities of cholinesterases in the cerebrospinal fluid (CSF) of AD patients. These studies suggest that treatment with rapidly-reversible cholinesterase inhibitors (e.g. donepezil, galantamine, tacrine) are associated with marked and significant upregulation of AChE activities and protein levels in the CSF of AD patients. In contrast, pseudo-irreversible cholinesterase inhibition (e.g. rivastigmine) is associated with a significant decrease in both CSF AChE and BuChE activities, with no upregulation of CSF protein levels. Additionally, donepezil is associated with a decrease in the level of the AChE-R isoform relative to the synaptic AChE-S isoform, whereas rivastigmine seems to increase this ratio. These findings suggest that these agents exert different effects on CSF cholinesterases. The clinical effects of these pharmacological differences are yet to be fully established.

To investigate whether serum levels of estradiol affect reproductive outcomes of normoresponder women undergoing fresh embryo transfer (ET) versus frozen-thawed ET (FET). Two hundred fifty-five normoresponder women underwent fresh ET in their first or second in vitro fertilization cycle. Ninety-two women with negative pregnacy test results underwent FET. Clinical and ongoing pregnancy rates, implantation, and live birth rates of women undergoing fresh ET versus FET were compared. One hundred forty-seven (57.65%) out of the 255 normoresponder women receiving FET had positive beta-human chorionic gonadotrophin (hCG) results. The remaining 108 women had negative beta-hCG results. The clinical pregnancy rates of the fresh ET group were found as 55.69% (n=142). Ninety-two of the 108 women with failed pregnancies underwent FET; 72.83% had positive beta-hCG results (n=67), and 70.65% had clinical pregnancy (n=65). Both biochemical and clinical pregnancy rates of women undergoing FET increased significantly (p<0.012 and p<0.013, respectively). Ongoing pregnancy (60.87% vs. 52.94%) and live birth rates (59.87% vs. 48.63%) were similar in both fresh and FET groups. Serum E2 levels of women who failed to conceive were significantly higher than those women did conceive. Serum progesterone levels of women who conceived versus those that did not were similar. The detrimental effect of high serum estradiol levels on endometrial receptivity could be prevented by FET.

Sensitive skin is a relatively common dermatologic condition and no optimal treatments have been established so far. Low-level laser/light therapy (LLLT) has been used for its biostimulative effect in various clinical settings. The purpose of this study was to investigate whether low-level laser/light therapy can improve sensitive skin clinically and to evaluate the effects of LLLT on skin in vitro. Twenty-eight patients complaining of sensitive skin were treated with low-level polarized light, and clinical results were evaluated using subjective and objective method. To investigate possible working mechanism of LLLT on skin, cultured human keratinocytes pretreated with nontoxic concentration of sodium lauryl sulfate (SLS) were used. Cytokines released from irritated keratinocytes after LLLT were analyzed. All patients showed subjective and objective improvement after treatment. No adverse effects were reported. The average number of LLLT sessions required to achieve clinical improvement was 9.9, and cumulative dose of LLLT was 71.3 J/cm(2) on the average. Erythema index decreased significantly after LLLT treatment (p = 0.017). In vitro assay showed that LLLT significantly reduced the release of VEGF from SLS-pretreated keratinocytes (p = 0.021). Our results suggest that LLLT could be a useful and safe treatment modality for sensitive skin, and modification of inflammatory cytokines released from irritated keratinocytes may be considered as one of plausible mechanisms in sensitive skin treated with LLLT.

The variability of demographic, social, genetic, and clinical factors might influence the time between the onset of symptoms and the diagnosis [diagnostic delay (DD)] of ankylosing spondylitis (AS) in different geographic areas. Different clinical manifestations in men and women affected by AS might indicate a possible role of gender in DD. The aim of the present study was to investigate the influence of demographic, social, genetic, and clinical factors on DD and the differences of DD between men and women related to the presence of different demographic, social, clinical, and genetic parameters in an Italian cohort of primary AS patients. A total of 135 Italian primary AS patients (45 female and 90 male, 27.9 ± 0.89 years old at onset) were studied. The DD, gender, education and work (manual or non-manual) levels, and type of first clinical presentation (inflammatory back pain, arthritis, enthesitis) at onset, family history of AS, and HLA B27 presence were analyzed. The DD (8.744 mean ±0.6869) was significantly higher in men (p = 0.0023), in axial presentation (p = 0.0021), and in manual work (even if with low significance, p = 0.047). The lower DD in women in comparison to that in men was likely related to higher education (p = 0.0045) and work (p = 0.0186) levels, peripheral involvement (p = 0.0009), and HLA B27 positivity (p = 0.0231). DD was higher in AS patients: male, employed in manual jobs, and with axial symptoms at onset. In men, DD seemed to be negatively influenced by lower level of education and work, axial clinical presentation, and HLA B27.

Years of experience and level of education are two important determinants of a clinician's expertise. While entry-to-practice criteria for admission to perfusion training in Canada changed from clinical experience-based criteria to education-based criteria in 2006, the effects of these changes have not been studied. To determine the academic and clinical backgrounds of perfusionists in Canada, ascertain perceptions about the adequacy of training and evaluate the effects of the changes on the composition of the perfusion community of Canada. An electronic questionnaire was distributed to all practicing perfusionists in Canada, addressing details regarding clinical experience, academic education and perceptions about the adequacy of training. Two hundred and twenty-eight questionnaires were completed, representing a 72% response rate. Perfusionists admitted under academic-based criteria have significantly higher levels of education (100% degree holders vs 69.1%, p<0.001), but less antecedent clinical training and experience (median, IQR: 0, 0 - 4.5 years vs 2, 2 - 8 years, p<0.0001), are younger (median age range 31-35 years vs 51-55 years, p<0.0001), more likely to be female (58.7% vs 41.3%, p=0.006) and are significantly more likely to enter perfusion because of attraction to the type of work (p=0.045). Many perfusionists (70, 32%) in Canada believe themselves inadequately trained for their clinical assignments outside the OR. In addition, 19% of perfusionists plan to retire over the next 10 years. The introduction of education-based entry criteria has changed the academic and clinical experience levels of perfusionists in Canada. Strategies designed to better prepare perfusionists for their clinical assignments outside the OR are merited.

Physiotherapy Students' Attitudes toward Psychiatry and Mental Health: A Cross-Sectional Study.

Connaughton, Joanne; Gibson, William

Purpose: A cross-sectional exploration of Notre Dame Australia physiotherapy students' attitudes toward psychiatry and mental illness, students' perceptions regarding preparation in this area for general clinical practice, and a cross-sectional investigation of current mental health-and psychiatry-related content in physiotherapy curricula across Australia and New Zealand. Methods: A questionnaire including demographic details, level of exposure to mental illness, and the Attitudes Toward Psychiatry-30 items (ATP-30) was completed by pre-clinical and clinically experienced physiotherapy students from the University of Notre Dame Australia. Students with clinical experience were asked additional questions about preparedness for practice. Staff of 10 of 17 physiotherapy programmes across Australia and New Zealand responded to an online questionnaire investigating relevant content and quantity of learning experiences in mental health. Results: Student response rate was 89%. Students generally had a positive attitude about psychiatry and mental health. Women were significantly more positive than men, and students who had completed clinical experience had a significantly more positive attitude. Physiotherapy program responses (response rate=59%) highlighted disparate approaches to psychiatry and mental health learning opportunities in terms of quantity and content. Conclusion: Entry-level physiotherapy students who have clinical experience generally have a more positive attitude toward psychiatry and people with mental illness. Given the prevalence of mental health problems and the increase in physical and mental health comorbidities, it is imperative that future clinicians have positive educational experiences in psychiatry. A coherent, integrated approach to mental illness and psychiatry is suggested for entry-level physiotherapy programmes in Australia and New Zealand.

Equipment management risk rating system based on engineering endpoints.

PubMed

James, P J

1999-01-01

The equipment management risk ratings system outlined here offers two significant departures from current practice: risk classifications are based on intrinsic device risks, and the risk rating system is based on engineering endpoints. Intrinsic device risks are categorized as physical, clinical and technical, and these flow from the incoming equipment assessment process. Engineering risk management is based on verification of engineering endpoints such as clinical measurements or energy delivery. This practice eliminates the ambiguity associated with ranking risk in terms of physiologic and higher-level outcome endpoints such as no significant hazards, low significance, injury, or mortality.

This study was to investigate the clinical efficacy of a gonadotrophin-releasing hormone agonist (GnRH-a) combined with high-intensity focused ultrasound (HIFU) ablation treatment for adenomyosis. A non-randomized prospective study. Gynaecological Minimally Invasive Centre in a single hospital. Patients with adenomyosis. Seventy-nine patients with adenomyosis were enrolled, including 55 patients in the control group treated with only HIFU and 24 patients in the study group treated with GnRH-a combined with HIFU. All the patients follow up 6 months after the HIFU procedure. The related parameters in the two groups were assessed before and 3 months as well as 6 months after treatment including serum levels of tumor marker and cytokine, volumes of uterine, adenomyotic lesion, and menstrual blood, as well as dysmenorrheal scores. Differences between the group treated with HIFU alone and the group treated with GnRH-a combined with HIFU. Before HIFU treatment, no significant difference was observed in serum levels of CA125, CA19-9, and interleukin-6 (IL-6), the volumes of uterine, adenomyotic lesion, and menstrual blood, as well as dysmenorrhea scores between the two groups. (P > 0.05). The serum CA125 levels significantly decreased in both groups after HIFU, but the serum CA125 levels in the study group were still significantly lower than those in the control group (P < 0.05). The volume of uterine and adenomyotic lesion significantly decreased in both groups after HIFU procedure, and decreased even more in the study group 3 and 6 months after treatment (P < 0.05). Dysmenorrhea scores and menstruation volumes significantly decreased in both groups after HIFU treatment. Moreover in the study group were significantly lower than those in the control group after 3 and 6 months (P < 0.05). No significant difference was observed in the rate of adverse effects between the two groups. The short-term follow-up results indicate that the combination of GnRH-a and HIFU treatment significantly decreased serum CA125 levels, volumes of uterine, adenomyotic lesion and menstrual blood, as well as dysmenorrhea scores, and improved the clinical outcomes compared with the HIFU ablation alone in patients with adenomyosis. However, the further follow-up is needed to explore the long-term effects. A combination of GnRH-a with HIFU in the treatment of adenomyosis significantly decreased serum CA125 levels, uterine and adenomyotic lesion volumes, dysmenorrhea scores, and menstrual blood volumes. © 2017 Royal College of Obstetricians and Gynaecologists.

Measurement feedback systems (MFSs) have been proposed as a means of improving practice. The present study examined the implementation of a MFS, the Contextualized Feedback System (CFS), in two community-based clinic sites. Significant implementation differences across sites provided a basis for examining factors that influenced clinician uptake of CFS. Following the theoretical implementation framework of Aarons, Hurlburt & Horwitz (2011), we coded qualitative data collected from eighteen clinicians (13 from Clinic U and 5 from Clinic R) who participated in semi-structured interviews about their experience with CFS implementation. Results suggest that clinicians at both clinics perceived more barriers than facilitators to CFS implementation. Interestingly, clinicians at the higher implementing clinic reported a higher proportion of barriers to facilitators (3:1 vs. 2:1); however, these clinicians also reported a significantly higher level of organizational and leadership supports for CFS implementation. Implications of these findings are discussed. PMID:25735619

This study was conducted to determine how closely nurses' perceptions of their clinical judgment abilities matched their demonstrated clinical judgment skills during a simulation. Seventy-four registered nurses participated in a simulation using a video format. After the simulation, the nurses self-assessed their performance using the Lasater Clinical Judgment Rubric. This rubric was then used to rate the nurses' actual performance in the simulation activity. The study results showed a significant discrepancy between nurses' perceptions of their own clinical judgment abilities and their demonstrated clinical judgment skills. Age and length of nursing experience enhanced the difference between the findings of self-assessment and actual performance. Younger nurses and those with 1 year or less of nursing experience were significantly more likely to have self-assessed their abilities at a much higher level compared with their actual skills.

In silico approaches have been proposed as a novel strategy to increase the repertoire of clinical trial designs. Realistic simulations of clinical trials can provide valuable information regarding safety and limitations of treatment protocols and have been shown to assist in the cost‐effective planning of clinical studies. In this report, we present a blueprint for the stepwise integration of internal, external, and ecological validity considerations in virtual clinical trials (VCTs). We exemplify this approach in the context of a model‐based in silico clinical trial aimed at anemia treatment in patients undergoing hemodialysis (HD). Hemoglobin levels and subsequent anemia treatment were simulated on a per patient level over the course of a year and compared to real‐life clinical data of 79,426 patients undergoing HD. The novel strategies presented here, aimed to improve external and ecological validity of a VCT, significantly increased the predictive power of the discussed in silico trial. PMID:29368434

Vascular calcifications are highly prevalent in hemodialysis patients. Dephosphorylated-uncarboxylated MGP (dp-ucMGP) was found to increase in vitamin K-deficient patients and may be associated with vascular calcifications. Supplementation of hemodialysis patients with vitamin K 2 (menaquinone-7) has been studied in Europe with a maximum 61% drop of dp-ucMGP levels. The aim of this study is to assess first the drop of dp-ucMGP in an Eastern Mediterranean cohort after vitamin K 2 treatment and second the correlation between baseline dp-ucMGP and vascular calcification score. This is a prospective, pre-post intervention clinical trial involving 50 hemodialysis patients who received daily 360 μg of menaquinone-7 for 4 weeks. At baseline they were assessed for plasma dp-ucMGP levels and vascular calcification scores (AC-24) as well as for other demographic, clinical and biological variables. Dp-ucMGP levels were measured a second time at 4 weeks. At baseline, dp-ucMGP levels were extremely elevated with a median of 3179.15 (1825.25; 4339.50) pM and correlated significantly with AC-24 (Spearman's rho = 0.43, P = 0.002). Using a bivariate regression analysis, the association between dp-ucMGP levels and AC-24 was most significant when comparing dp-ucMGP levels less than 1000 to those more than 1000 pM (P = 0.02). Dp-ucMGP levels higher than 5000 pM were significantly associated with females, patients with recent fracture and patients with lower serum albumin (respectively P = 0.02, 0.004 and 0.046). The average drop of dp-ucMGP at 4 weeks of treatment was found to be 86% with diabetics having the lowest drop rate (P = 0.01). Vitamin K deficiency, as assessed by high dp-ucMGP levels, is profound in hemodialysis patients from the Eastern Mediterranean region and it is significantly correlated with vascular calcifications. Daily 360 μg of menaquinone-7, given for 4 weeks, effectively reduces dp-ucMGP in this population. Future studies are needed to assess the changes in vascular calcifications in hemodialysis patients treated with vitamin K 2 over a longer follow-up period. The clinical trial was registered on clinicaltrials.gov (Identification number NCT02876354 , on August 11, 2016).

Probabilistic topic models provide an unsupervised method for analyzing unstructured text, which have the potential to be integrated into clinical automatic summarization systems. Clinical documents are accompanied by metadata in a patient's medical history and frequently contains multiword concepts that can be valuable for accurately interpreting the included text. While existing methods have attempted to address these problems individually, we present a unified model for free-text clinical documents that integrates contextual patient- and document-level data, and discovers multi-word concepts. In the proposed model, phrases are represented by chained n-grams and a Dirichlet hyper-parameter is weighted by both document-level and patient-level context. This method and three other Latent Dirichlet allocation models were fit to a large collection of clinical reports. Examples of resulting topics demonstrate the results of the new model and the quality of the representations are evaluated using empirical log likelihood. The proposed model was able to create informative prior probabilities based on patient and document information, and captured phrases that represented various clinical concepts. The representation using the proposed model had a significantly higher empirical log likelihood than the compared methods. Integrating document metadata and capturing phrases in clinical text greatly improves the topic representation of clinical documents. The resulting clinically informative topics may effectively serve as the basis for an automatic summarization system for clinical reports. Copyright © 2016 Elsevier Inc. All rights reserved.

To explore the expression and clinical significance of P-glycoprotein (P-gp)/mdr1mRNA, multidrug resistance-associated protein (MRP) and lung resistance protein (LRP) in newly diagnosed non-Hodgkin's lymphoma. mdr1 mRNA of in 41 patients with non-Hodgkin's lymphoma was assayed by semi-quantitative RT-PCR. The expressions of P-gp, MRP and LRP proteins in lymph node viable blasts were identified by flow cytometry. The results were compared with those obtained from control cases, and the correlation of the changes with clinical outcomes was analyzed. (1) Among the 41 cases, the positive expression of P-gp protein was detected in 8 cases, MRP in 7 cases, LRP in 15 cases, and mdr 1 mRNA in 11 cases. (2) The P-gp and LRP levels in NHL were significantly higher than those in control group, but MRP wasn't. The P-gp over-expression was significantly associated with mdr1mRNA (r = 0.396, P = 0.01). No correlation was showed among the expressions of P-gp, MRP and LRP. (3) Patients with P-gp expression had a poorer outcome of chemotherapy than those with P-gp-negative (P = 0.005). P-gp expression was significantly associated with higher clinical stage (P = 0.046) and elevated serum lactate dehydrogenase level (P = 0.032), but not associated with malignant degree (P = 0.298). MRP had no impact on the outcome of chemotherapy (P = 0.212), and wasn't significantly associated with higher clinical stage (P = 0.369), elevated LDH (P = 0.762) and higher malignant degree (P = 0.451). Patients with LRP expression had a poorer outcome of chemotherapy than those LRP-negative (P = 0.012). LRP expression was significantly associated with higher clinical stage (P = 0.0019), elevated LDH (P = 0.02) and higher malignant degree (P = 0.01). The data of this study indicate that P-gp and LRP expressions but not MRP expression are important in the mechanism of drug resistance associated with a poor clinical outcome in previously untreated NHL.

Some clinical studies have reported reduced peripheral glial cell line-derived neurotrophic factor (GDNF) level in elderly patients with major depressive disorder (MDD). We verified whether a reduction in plasma GDNF level was associated with MDD. Plasma GDNF level was measured in 23 healthy control subjects and 23 MDD patients before and after 6 weeks of treatment. Plasma GDNF level in MDD patients at baseline did not differ from that in healthy controls. Plasma GDNF in MDD patients did not differ significantly from baseline to the end of treatment. GDNF level was significantly lower in recurrent-episode MDD patients than in first-episode patients before and after treatment. Our findings revealed significantly lower plasma GDNF level in recurrent-episode MDD patients, although plasma GDNF levels in MDD patients and healthy controls did not differ significantly. The discrepancy between our study and previous studies might arise from differences in the recurrence of depression or the ages of the MDD patients.

The goal of this study was to evaluate a health literacy instrument based on the Rapid Estimate of Adult Literacy in Medicine (REALM) that incorporates dental and medical terms into one 84-item Rapid Estimate of Adult Literacy in Medicine and Dentistry (REALM-D) measure and determine its association with patient characteristics of a culturally diverse dental clinic population. Methods An 84-item dental/medical health literacy word list and a 48-item health beliefs and attitudes survey was provided to a sample of 200 adult patients seeking treatment for the first time at an oral diagnosis clinic located in a large urban medical center in Los Angeles, California. Results Of the total sample, 154 participants read all of list 1 correctly, 141 read list 2 correctly, and only 38 read list 3 correctly. Nonwhite participants had significantly lower REALM-D scores at each level of difficulty as well as the total scale score compared to white participants. Participants who reported English as not their main language had significantly lower REALM-D scores. REALM-D scores also varied significantly by level of education among participants where as level of education increased, oral health literacy increased. At a bivariate level, race, education, and English as a main language remain predictive of health literacy in a regression model. An interaction between education and English as a main language was significant. Conclusions The REALM-D is an effective instrument for use by medical and dental clinicians in detecting differences among people of different backgrounds and for whom English was not their primary language.

Background Schizophrenia is a chronic illness which brings detrimental effects in the caregivers' health. This study was aimed at highlighting the socio-demographic, clinical and psychosocial factors associated with the subjective Quality of Life (QOL) of Malaysian of primary family caregivers of subjects with schizophrenia attending an urban tertiary care outpatient clinic in Malaysia. Methods A cross-sectional study was performed to study patient, caregiver and illness factors associated with the QOL among 117 individuals involved with caregiving for schizophrenia patients. The study used WHOQOL-BREF to assess caregivers' QOL and Brief Psychiatric Rating Scale (BPRS) to assess the severity of patients' symptoms. Social Readjustment Rating Scale (SRRS) assessed the stress level due to life events. Results The mean scores of WHOQOL-BREF in physical, psychological, social and environmental domains were 66.62 (14.36), 61.32 (15.52), 62.77 (17.33), 64.02 (14.86) consecutively. From multiple regression analysis, factors found to be significantly associated with higher QOL were higher educational level among caregivers in social and environmental domains; caregivers not having medical problem/s in physical and psychological domains; later onset and longer illness duration of illness in social domains; patients not attending day care program in environmental domain; lower BPRS score in physical and environmental domains. SRRS score of caregivers was also found to have a significant negative correlation with QOL in environmental and psychological domains. Other factors were not significantly associated with QOL. Conclusion Caregivers with more social advantages such as higher educational level and physically healthier and dealing with less severe illness had significantly higher QOL in various aspects. Supporting the caregivers in some of these modifiable factors in clinical practice is important to achieve their higher level QOL. PMID:21651770

An open-label study with one treatment arm was conducted to investigate changes in health-related biomarkers (blood pressure and liver enzyme activity) and the safety of 4 weeks of consuming a purple-fleshed sweet potato beverage in Caucasian subjects. Twenty healthy adults, 18–70 years of age, with a body mass index >25 kg/m2, elevated blood pressure and elevated levels of liver function biomarkers consumed two cartons of purple-fleshed sweet potato beverage (125 ml, including 117 mg anthocyanin per carton) daily for 4 weeks. Hematology, serum clinical profile, dipstick urinalysis and blood pressure were determined before consumption, at 2 and 4 weeks of consumption and after a 2-week washout period. A trend was found toward lowering systolic blood pressure during the treatment period (p=0.0590). No significant changes were found in diastolic blood pressure throughout the study period. Systolic blood pressure was significantly lower after 4 weeks of consumption compared with before consumption (p=0.0125) and was significantly higher after the 2-week washout period compared with after consumption (p=0.0496). The serum alanine aminotransferase level significantly increased over time, but aspartate aminotransferase and γ-glutamyltransferase levels stayed within the normal range of reference values. Safety parameters of the blood and urine showed no clinically relevant changes. The consumption of a purple-fleshed sweet potato beverage for 4 weeks resulted in no clinically relevant changes in safety parameters of the blood and urine and showed a trend toward lowering systolic blood pressure.

To determine the content of integrated curricula, clinical concepts and the underlying basic science concepts need to be made explicit. Preconstructed concept maps are recommended for this purpose. They are mainly constructed by experts. However, concept maps constructed by residents are hypothesized to be less complex, to reveal more tacit basic science concepts and these basic science concepts are expected to be used for the organization of the maps. These hypotheses are derived from studies about knowledge development of individuals. However, integrated curricula require a high degree of cooperation between clinicians and basic scientists. This study examined whether there are consistent variations regarding the articulation of integration when groups of experienced clinicians and basic scientists and groups of residents and basic scientists-in-training construct concept maps. Seven groups of three clinicians and basic scientists on experienced level and seven such groups on resident level constructed concept maps illuminating clinical problems. They were guided by instructions that focused them on articulation of integration. The concept maps were analysed by features that described integration. Descriptive statistics showed consistent variations between the two expertise levels. The concept maps of the resident groups exceeded those of the experienced groups in articulated integration. First, they used significantly more links between clinical and basic science concepts. Second, these links connected basic science concepts with a greater variety of clinical concepts than the experienced groups. Third, although residents did not use significantly more basic science concepts, they used them significantly more frequent to organize the clinical concepts. The conclusion was drawn that not all hypotheses could be confirmed and that the resident concept maps were more elaborate than expected. This article discusses the implications for the role that residents and basic scientists-in-training might play in the construction of preconstructed concept maps and the development of integrated curricula.

To analyse the prevalence of hypothyroidism in rheumatoid arthritis (RA) patients and to elucidate its correlation with disease activity. A total of 52 RA patients were enrolled in this study. All patients were assessed fully clinically and underwent routine laboratory investigation including thyroid function testing. Hypothyroidism (defined as having a TSH level >4.20 μIU/mL) was observed in 20/52 (38.4%). Erythrocyte sedimentation rates (ESR) were found significantly elevated in patients with hypothyroidism compared to those without (36.3 ± 24.2 vs. 24.6 ± 9.0 mm/h). Disease activity parameters such as DAS-28-ESR, tender joint count; VAS scores were also significantly higher in the former. A significant correlation with serum TSH levels was observed with ESR and DAS-28-ESR. Thyroid function test should be included in clinical evaluation of RA patients. © The Author(s) 2016.

Serum tumor markers play important roles in diagnosis, response and prognosis monitoring for lung cancer. The clinical significance of serum level of tissue polypeptide specific antigen (TPS) was investigated in diagnosis, response monitoring and prognosis in patients with lung cancer, compared with carcinoembryonic antigen (CEA), precursor of gastrin-releasing peptide (Pro-GRP) and cytokeratin-19-fragments (CYFRA21-1). Blood samples of eighty-two patients with lung cancer before treatment and some after chemotherapy were measured by ELISA for four tumor markers. Compared with lung benign diseases group and health control group, the positive rates and levels of TPS, CEA and Pro-GRP in patients with lung cancer were higher, with statistically significant difference. TPS in extensive-small cell lung cancer was significant higher than that in limited-small cell lung cancer. The positive rates and levels of TPS, CEA and Pro-GRP in patients after treatment had significant decreases compared with before treatment. TPS was an independent prognostic factor of non-small cell lung cancer. TPS is valuable to diagnosis, response monitoring for patients with lung cancer, moreover, it maybe a useful factor of prognosis of non-small cell lung cancer.

In order to analyze the association between body mass index (BMI), lipid profile and clinical symptoms in patients with fibromyalgia, we assessed BMI levels, lipid profile and its association with clinical symptoms in 183 patients with fibromyalgia. The patients were evaluated using tender points, FIQ and Visual Analogue Scales of pain (VAS). Serum lipid profile analysis (total cholesterol, triglyceride, HDL, LDL and VLDL), and biochemical parameters were measured in the biochemistry laboratory. The BMI distribution of the nonobese, overweight and obese patients' groups were relatively even with 37.7, 35.5 and 26.8%, respectively, with a mean BMI of 27.3 ± 4.9. The number of tender points showed significantly positive correlation with higher BMI (P < 0.05). A total of 57.9% of patients showed increased levels of total cholesterol, 63.4 % increased levels of LDL cholesterol and 19.9% high levels of triglycerides. BMI, total cholesterol and triglycerides showed high association with some clinical parameters. Overweight and lipid profile could be associated with fibromyalgia symptoms. A treatment program with weight loss strategies, and control in diet and increased physical activity is advised to patients.

Hormones (progesterone and estradiol) change greatly during pregnancy; however, the mechanism of hormonal changes on gingival inflammation is still unclear. This study is to evaluate the effects of hormonal changes during pregnancy on gingival inflammation and interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in gingival crevicular fluid (GCF). 30 periodontally healthy pregnant women were evaluated in the first, second, and third trimesters. 20 periodontally healthy nonpregnant women were evaluated twice (once per subsequent month). Clinical parameters including probing pocket depth (PPD), bleeding index (BI), gingival index (GI), clinical attachment level (CAL), and plaque index (PLI) were recorded. GCF levels of IL-1β and TNF-α and serum levels of progesterone and estradiol were measured. From the data, despite low PLI, BI and GI increased significantly during pregnancy; however, no significant changes in PLI, CAL, IL-1β, or TNF-α GCF levels were observed. Although IL-1β, not TNF-α, was higher in pregnant group than in nonpregnant group, they showed no correlation with serum hormone levels during pregnancy. GI and BI showed significant positive correlation with serum hormone levels during pregnancy. This study suggests that sex hormone increase during pregnancy might have an effect on inflammatory status of gingiva, independent of IL-1β and TNF-α in GCF. PMID:27034591

Clinical education is one of the most important components of the resource generation function of health systems, and it has a very important role in graduates' competency with respect to effective, practical education. This study aimed to assess the quality of clinical services in Kerman's teaching hospitals located in southeastern Iran. This cross-sectional study was conducted in 2011 on 303 medical students at different levels of medical education at Kerman's teaching hospitals. A modified SERVQUAL instrument was used to collect the data after its validity and reliability were checked. The data were analyzed by SPSS 18.0 using the paired t-test, Kruskal-Wallis, and post hoc tests, when appropriate. In all five dimensions of quality, gaps were observed between students' perceptions and expectations as follows: Assurance (mean = -1.18), Responsiveness (-1.56), Empathy (-1.4), Reliability (-1.27), and Tangibles (-1.21). There was a significant difference between the quality perceptions and expectations of the medical students (p < 0.001). A significant difference was observed between three educational levels, including externships, internships, and assistantships regarding the dimensions of the quality gaps (p < 0.001). The clinical services provided by teaching hospitals in the study did not meet the students' expectations at any of the three educational levels. As we precisely assessed the dimensions and items that had the higher quality gaps, it was apparent that, for most part, clinical education officials could improve the quality by designing interventions, which would not be very difficult to do.

Sweating can worsen atopic dermatitis (AD). The purpose of this work was to study the associations between reactivity to autologous sweat and the clinical severity of AD as well as investigate the possible wheal-inducing factors of sweat. Intracutaneous skin tests with autologous sweat were performed on 50 AD patients and 24 control subjects. In skin biopsies, tryptase and PAR-2 were enzyme and immunohistochemically stained. The associations between skin test reactivity and sweat histamine concentration, tryptase or chymase activity levels, tryptase or PAR-2 expression and AD clinical severity or IgE levels were investigated. The wheal reactions in the intracutaneous tests with autologous sweat were positive, weakly positive and negative in 38, 34 and 28% of the AD patients, respectively, and in 4, 46 and 50% of the healthy controls, respectively (p = 0.008). In AD, the wheal reaction was associated significantly with clinical severity, serum total and specific IgE levels and sweat tryptase activity, but not with sweat histamine and chymase. In nonlesional AD skin, the percentage of PAR-2+ mast cells (MCs) or the number of tryptase+ MCs did not differ significantly between the intracutaneous test reactivity groups. Reactivity to autologous sweat correlates with the clinical severity of AD, and tryptase may be one of the factors involved in the sweat-induced wheal. © 2016 S. Karger AG, Basel.

Considering the pathologic importance of oxidative stress and altered lipid metabolism in osteoarthritis (OA), this study aimed to investigate the effect of l-carnitine supplementation on oxidative stress, lipid profile, and clinical status in women with knee OA. We hypothesized that l-carnitine would improve clinical status by modulating serum oxidative stress and lipid profile. In this randomized double-blind, placebo-controlled trial, 72 overweight or obese women with mild to moderate knee OA were randomly allocated into 2 groups to receive 750 mg/d l-carnitine or placebo for 8 weeks. Dietary intake was evaluated using 24-hour recall for 3 days. Serum malondialdehyde (MDA), total antioxidant capacity (TAC) and lipid profile, visual analog scale for pain intensity, and patient global assessment of severity of disease were assessed before and after supplementation. Only 69 patients (33 in the l-carnitine group and 36 in the placebo group) completed the study. l-Carnitine supplementation resulted in significant reductions in serum MDA (2.46 ± 1.13 vs 2.16 ± 0.94 nmol/mL), total cholesterol (216.09 ± 34.54 vs 206.12 ± 39.74 mg/dL), and low-density lipoprotein cholesterol (129.45 ± 28.69 vs 122.05 ± 32.76 mg/dL) levels compared with baseline (P < .05), whereas these parameters increased in the placebo group. Serum triglyceride, high-density lipoprotein cholesterol, and TAC levels did not change significantly in both groups (P > .05). No significant differences were observed in dietary intake, serum lipid profile, MDA, and TAC levels between groups after adjusting for baseline values and covariates (P > .05). There were significant intragroup and intergroup differences in pain intensity and patient global assessment of disease status after supplementation (P < .05). Collectively, l-carnitine improved clinical status without changing oxidative stress and lipid profile significantly in women with knee OA. Copyright © 2015 Elsevier Inc. All rights reserved.

Background ST2 is a member of the interleukin-1 receptor family with a soluble form that is markedly upregulated on application of biomechanical strain to cardiac myocytes. Circulating ST2 levels are elevated in the setting of acute myocardial infarction, but the predictive value of ST2 independent of traditional clinical factors and of an established biomarker of biomechanical strain, N-terminal prohormone B-type natriuretic peptide (NT-proBNP), has not been established. Methods and Results We measured ST2 at baseline in 1239 patients with ST-elevation myocardial infarction from the CLopidogrel as Adjunctive ReperfusIon TherapY–Thrombolysis in Myocardial Infarction 28 (CLARITY-TIMI 28) trial. Per trial protocol, patients were to undergo coronary angiography after 2 to 8 days and were followed up for 30 days for clinical events. In contrast to NT-proBNP, ST2 levels were independent of clinical factors potentially related to chronic increased left ventricular wall stress, including age, hypertension, prior myocardial infarction, and prior heart failure; levels also were only modestly correlated with NT-proBNP (r=0.14). After adjustment for baseline characteristics and NT-proBNP levels, an ST2 level above the median was associated with a significantly greater risk of cardiovascular death or heart failure (third quartile: adjusted odds ratio, 1.42; 95% confidence interval, 0.68 to 3.57; fourth quartile: adjusted odds ratio, 3.57; 95% confidence interval, 1.87 to 6.81; P<0.0001 for trend). When both ST2 and NT-proBNP were added to a model containing traditional clinical predictors, the c statistic significantly improved from 0.82 (95% confidence interval, 0.77 to 0.87) to 0.86 (95% confidence interval, 0.81 to 0.90) (P=0.017). Conclusions In ST-elevation myocardial infarction, high baseline ST2 levels are a significant predictor of cardiovascular death and heart failure independently of baseline characteristics and NT-proBNP, and the combination of ST2 and NT-proBNP significantly improves risk stratification. These data highlight the prognostic value of multiple, complementary biomarkers of biomechanical strain in ST-elevation myocardial infarction. PMID:18378613

To explore the associations between the polymorphisms and protein levels of interleukin-6 (IL-6) gene and gout disease. A total of 120 male gout patients and 184 healthy controls were enrolled. Each patient was matched with 1-2 gout-free controls by age within three years. Four polymorphisms in the promoter of IL-6 gene, including -597G/A, -572C/G, -373A(m)T(n), and -174G/C, and the IL-6 levels were analyzed. The clinical characteristics and biochemical markers in plasma were measured, including age of gout onset, duration of gout history, tophus number, gout attack frequency, uric acid, total cholesterol, triglycerides and creatinine. The mean IL-6 level for gout patients was 9.80 (+/-11.76 pg/ml) which showed no significant difference from the controls (7.06+/-7.58 pg/ml, p=0.230). When the IL-6 levels were dichotomized according to the median value (5 pg/ml), there were significantly higher proportions of the gout patients (59.66%) than controls (44%) with high IL-6 levels (OR=1.88, 95% CI=1.17-3.02, p=0.008). Unique genotype was found at polymorphisms -174G/C and -597G/A. Neither the polymorphisms -572C/G nor -373A(m)T(n) in the genotype or allele distributions showed a significant association related to clinical characteristics, biochemical markers, IL-6 levels or gout disease (all p>0.05). Those with gout disease have greater proportions of high IL-6 levels in plasma than controls, and there is no significant association between the four polymorphisms in the promoter region of IL-6 gene and gout disease.

Idiopathic inflammatory myopathies are a group of clinically heterogeneous diseases, which have been classified by myositis specific antibodies recently. The anti-SRP positive subset of this group is characterized by more severe clinical prognosis than other myositis specific antibody positive types. Our goal was to compare 16 anti-SRP positive patients in the Division of Clinical Immunology, Department of Internal Medicine, University of Debrecen with 16 antibody negative ones. Muscle strength validated in both groups by the manual muscle test proved to be significantly decreased both before and after therapy (χ 2 = 0.006 and 0.019) in the anti-SRP positive group. Muscle-specific inflammatory laboratory parameters showed significant difference only in case of LDH-levels after therapy. Both groups showed good clinical response to first line steroid treatment, yet the significantly higher rate of second line administration suggests worse therapeutic response of the antibody positive group. Based on these facts we determined poor clinical prognosis and therapeutic response of the anti-SRP positive group. Orv Hetil. 2017; 158(35): 1382-1389.

Context: Severe acute respiratory syndrome (SARS) is a newly emerging infectious disease and how the frontline community doctors respond to it is not known. Objectives: To explore the impact of SARS on general practitioners (GPs) in Hong Kong. Design: A cross sectional survey. Setting: Community based primary care clinics. Participants: 183 family medicine tutors affiliated with a local university. Postal survey sent to all tutors with a 74.8% response rate. Main outcome measures: Change of clinical behaviour and practices during the epidemic; anxiety level of primary care doctors. Results: All agreed SARS had changed their clinical practices. Significant anxiety was found in family doctors. Three quarters of respondents recalled requesting more investigations while a quarter believed they had over-prescribed antibiotics. GPs who were exposed to SARS or who had worked in high infection districts were less likely to quarantine themselves (10.8% versus 33.3%; p<0.01; 6.5% versus 27.5%; p<0.01 respectively). Exposure to SARS, the infection rates in their working district, and anxiety levels had significant impact on the level of protection or prescribing behaviour. Conclusion: The clinical practice of GPs changed significantly as a result of SARS. Yet, those did not quarantine themselves suggesting other factors may have some part to play. As failure to apply isolation precautions to suspected cases of SARS was one major reason for its spread, a contingency plan from the government to support family doctors is of utmost importance. Interface between private and public sectors are needed in Hong Kong to prepare for any future epidemics. PMID:14966227

It is now well documented that certain anesthetic techniques may influence long term outcome in cancer patients undergoing surgery. More recently, local anesthetics proved certain antiproliferative effects in cancer cells. In our study, we aimed to investigate if lidocaine has antiproliferative effects in human hepatocarcinoma cells and to identify possible mechanisms of these effects. We investigated the inhibitory effect of different concentrations of lidocaine on the proliferation of cultured HepG2 human hepatocarcinoma cells and LX2 normal liver fibroblasts. Cells were exposed to nine different concentrations of lidocaine for 72h. MTT assay was used to investigate HepG2 and LX2 proliferation while Western blotting was used for detection of p53 expression level. Our data showed that lidocaine inhibited cell proliferation in a concentration-dependent manner in both HepG2 and LX2. The antiproliferative effects of lidocaine in LX2 were significantly diminished as compared with those in HepG2 (p< 0.001). Similarly, the expression level of p53 was significant decreased in HepG2 lines treated with lidocaine as compared with control and LX2 (p = 0.0241). In clinically relevant concentrations, lidocaine had significant antiproliferative effects on human hepatocarcinoma cells. These effects were time and dose-dependent. One of the possible mechanisms of these effects is by modifying the P53 expression level. The relevance of these findings in clinical practice is limited; clinical impact of these effects on the outcome of patients with hepatocarcinoma undergoing surgery or minimal invasive procedures needs to be demonstrated in future animal models and clinical studies.

Liu, Chenchen; Yue, Ben; Yuan, Chenwei

The THO complex 1 (Thoc1) is a nuclear matrix protein playing vital roles in transcription elongation and mRNA export. Recently, aberrant expression of Thoc1 has been reported in an increasing array of tumor types. However, the clinical significance of Thoc1 expression in colorectal cancer (CRC) is still unknown. The present study aimed to characterize the expression of Thoc1 in human CRC and evaluate its clinical significance. Quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting analyses showed that the mRNA and protein expression of Thoc1 in CRC specimens was significantly higher than that in adjacent normal colon mucosae. Immunohistochemistry (IHC)more » was conducted to characterize the expression pattern of Thoc1 in 185 archived paraffin-embedded CRC specimens. Statistical analyses revealed that high levels of Thoc1 expression were associated with the clinical stages and tumor differentiation. CRC patients with high levels of Thoc1 expression had poorer overall-survival and disease-free survival, whereas those with lower levels of Thoc1 expression survived longer. Furthermore, multivariate Cox regression analyses demonstrated that Thoc1 expression remained an independent prognostic factor for increased disease recurrence and decreased survival. Our results suggest for the first time that Thoc1 is involved in the development and progression of CRC, and elevated expression of Thoc1 is associated with aggressive phenotype and poor prognosis in CRC. These findings may prove to be clinically useful for developing a new therapeutic target of CRC treatment.« less

In patients with vitiligo, the clinical and laboratory features of the disease may vary according to time of onset. This is addressed in the literature by only a few studies with conflicting results. The aim of this study was to determine the demographic and clinical features of patients with non-segmental vitiligo and to establish the association between vitiligo and autoimmune diseases with a focus on time of disease onset. A total of 224 vitiligo patients for whom complete medical records were available were evaluated retrospectively. Demographic data, scores on the Vitiligo Area Score Index (VASI), clinical features, vitiligo disease activity, repigmentation status, presence of any accompanying autoimmune disease, antinuclear antibody (ANA) titers, serum levels of glucose, thyroid-stimulating hormone (TSH), thyroxine (T4) hormone, anti-thyroid peroxidase (anti-TPO), and anti-thyroglobulin (anti-TG) were recorded. The prevalence of halo nevi was significantly higher (P < 0.001) among children than in other patient groups. The prevalence of leukotrichia was higher in adults with adult-onset disease than in either pediatric patients or adults with childhood-onset disease (P = 0.002). Both anti-TG and anti-TPO levels were significantly higher in adults with adult-onset disease than in pediatric patients and adult patients with childhood-onset disease. The prevalence of autoimmune disease was 22.2%. Anti-TG levels were significantly higher in patients with treatment-related repigmentation than in those without repigmentation. This study shows that clinical features and associations with autoimmune disease may vary according to the age of onset of vitiligo. © 2017 The International Society of Dermatology.

Background Most studies on risk factors for development of coronary heart disease (CHD) have been based on the clinical outcome of CHD. Our aim was to identify factors that could predict the development of ECG markers of CHD, such as abnormal Q/QS patterns, ST segment depression and T wave abnormalities, in 70-year-old men, irrespective of clinical outcome. Methods Predictors for development of different ECG abnormalities were identified in a population-based study using stepwise logistic regression. Anthropometrical and metabolic factors, ECG abnormalities and vital signs from a health survey of men at age 50 were related to ECG abnormalities identified in the same cohort 20 years later. Results At the age of 70, 9% had developed a major abnormal Q/QS pattern, but 63% of these subjects had not been previously hospitalized due to MI, while 57% with symptomatic MI between age 50 and 70 had no major Q/QS pattern at age 70. T wave abnormalities (Odds ratio 3.11, 95% CI 1.18–8.17), high lipoprotein (a) levels, high body mass index (BMI) and smoking were identified as significant independent predictors for the development of abnormal major Q/QS patterns. T wave abnormalities and high fasting glucose levels were significant independent predictors for the development of ST segment depression without abnormal Q/QS pattern. Conclusion T wave abnormalities on resting ECG should be given special attention and correlated with clinical information. Risk factors for major Q/QS patterns need not be the same as traditional risk factors for clinically recognized CHD. High lipoprotein (a) levels may be a stronger risk factor for silent myocardial infarction (MI) compared to clinically recognized MI. PMID:16519804

Health-related quality of life (HR-QOL) in patients with celiac disease is reduced compared to the general population. We investigated the association between HR-QOL and clinical, laboratory findings using the previously validated CD-QOL (celiac disease-specific quality of life) instrument in patients with celiac disease. To our knowledge, no study has previously explored the relationship between HR-QOL and clinical, laboratory parameters in celiac patients. Patients who received care at the Allegheny Health Network Celiac Center, Pittsburgh, PA were asked to complete the CD-QOL questionnaire. A cross sectional study with predetermined clinical and laboratory parameters was performed. Data collected included IgA anti-tissue transglutaminase (tTG) antibody titers, iron studies, calcium, vitamin A, B12, 25 OH vitamin D, and E levels. Correlation between clinical findings and CD-QOL was also assessed. Seventy-eight out of 124 patients who completed the questionnaire was included in the analysis. Patients with concomitant irritable bowel syndrome (IBS) had significantly reduced HR-QOL with CD-QOL score of 52.4 ± 11.3 vs. 44.6 ± 12.9 in those without IBS (p = .009). There was no difference in HR-QOL in relation to IgA tTG titers or vitamin D levels. Of note, there was a trend towards correlation between higher level of vitamin E and better QOL (r = -0.236, p = .074). Celiac patients with concomitant IBS have reduced HR-QOL. There was no statistically significant association between HR-QOL and laboratory parameters or levels of micronutrients.

The objective was to follow-up the study 'High incidence of defective ultrasound transducers in use in routine clinical practice' and evaluate if annual testing is good enough to reduce the incidence of defective ultrasound transducers in routine clinical practice to an acceptable level. A total of 299 transducers were tested in 13 clinics at five hospitals in the Stockholm area. Approximately 7000-15,000 ultrasound examinations are carried out at these clinics every year. The transducers tested in the study had been tested and classified as fully operational 1 year before and since then been in normal use in the routine clinical practice. The transducers were tested with the Sonora FirstCall Test System. There were 81 (27.1%) defective transducers found; giving a 95% confidence interval ranging from 22.1 to 32.1%. The most common transducer errors were 'delamination' of the ultrasound lens and 'break in the cable' which together constituted 82.7% of all transducer errors found. The highest error rate was found at the radiological clinics with a mean error rate of 36.0%. There was a significant difference in error rate between two observed ways the clinics handled the transducers. There was no significant difference in the error rates of the transducer brands or the transducers models. Annual testing is not sufficient to reduce the incidence of defective ultrasound transducers in routine clinical practice to an acceptable level and it is strongly advisable to create a user routine that minimizes the handling of the transducers.
