The utility of measuring carcinoembryonic antigen(CEA) and cancer antigen 15-3 (CA15-3) levels in patients with breast cancer remains controversial. The present study aims to investigate the prognostic value of preoperative serum CEA and CA15-3 levels in breast cancer patients. Serum preoperative CEA and CA 15-3 concentration levels were measured in a total of 432 breast cancer patients. The association of tumor markers levels with clinicopathological parameters and outcomes were analyzed. Elevated serum levels of CEA and CA15-3 were identified in 47 (10.9%) and 60(13.9%) patients, respectively. Larger tumor size, advanced axillary lymph nodal and TNM stage exhibited higher proportion of elevated CEA and CA15-3 levels. The elevation of CEA levels was significantly greater in patients with HER2 positive tumors, and the elevation of CA15-3 levels was significantly greater in ER negative breast patients. Univariate and multivariate Cox's regression analysis revealed that elevated preoperative CEA and CA 15-3 levels were independent prognostic factors for DFS and OS. When considering the combination of both markers levels, patients with both elevated markers presented the worst survival. Independent prognostic significance of elevated preoperative serum CEA and CA15-3 levels were reconfirmed in Luminal B breast cancer. Preoperative serum levels of CEA and CA15-3 are independent prognostic parameters for breast cancer.

Pancreatic cancer presents the worst survival rates of all neoplasms. Surgical resection is the only potentially curative treatment, but is associated with high complication rates and outcome is bad even in those resected cases. Therefore, candidates amenable for resection must be carefully selected. Identification of prognostic factors preoperatively may help to improve the treatment of these patients, focusing on individually management based on the expected response. We perform a retrospective study of 59 patients with histological diagnosis of pancreatic carcinoma between 1999 and 2003, looking for possible prognostic factors. We analyze 59 patients, 32 males and 27 females with a mean age of 63.8 years. All the patients were operated, performing palliative surgery in 32% and tumoral resection in 68%, including pancreaticoduodenectomies in 51% and distal pancreatectomy in 17%. Median global survival was 14 months (Range 1-110).We observed that preoperative levels of hemoglobin under 12 g/dl (p = 0.0006) and serum albumina under 2.8 g/dl (p = 0.021) are associated with worse survival. Preoperative levels of hemoglobin and serum albumina may be prognostic indicators in pancreatic cancer.

Angiogenesis is a multistep process in which many growth factors and cytokines have an essential role. Vascular endothelial growth factor (VEGF) is a potent angiogenic agent that acts as a specific mitogen for vascular endothelial cells through specific cell surface receptors. The interleukin-6 (IL-6) pathway is another mechanism linking angiogenesis to malignancy. C-reactive protein (CRP), a representative marker for inflammation, is known for its association with disease progression in many cancer types. The aim of this study was to determine preoperative serum levels of VEGF, IL-6, and CRP in colorectal carcinoma, and to correlate them with disease status and prognosis. A 132 of 143 patients who underwent curative resection for colorectal cancer were enrolled in this study. 11 patients with resection margin positive were excluded. Factors considered in analysis of the relationship between VEGF, IL-6, and CRP and histological findings. Patient prognosis was investigated. Serum levels of VEGF and IL-6 were assessed using Enzyme-Linked Immuno-Sorbent Assay (ELISA), and CRP was measured using immunoturbidimetry. Median follow-up duration was 18.53 months (range 0.73-43.17 months) and median age of the patients was 62 years (range, 26-83 years). Mean and median levels of VEGF and CRP in colorectal cancer were significantly higher than in the normal control group; 608 vs. 334 pg/mL and 528 (range 122-3242) vs. 312 (range 16-1121) (p < 0.001); 1.05 mg/dL vs. 0.43 mg/dL and 0.22 (range 0.00-18.40) vs. 0.07 (range 0.02-6.94) (p = 0.002), respectively. However mean and median level of IL-6 in patients were not significantly higher than in control; 14.33 pg/mL vs. 5.65 pg/mL and 6.00 (range 1.02-139.17) vs. 5.30 (4.50-13.78) (p = 0.327). Although IL-6 and CRP levels were not correlated with other pathological findings, VEGF level was significantly correlated with tumor size (p = 0.012) and CEA (p = 0.038). When we established the cutoff value for VEGF (825 pg/mL), IL-6 (8

Objective: To study the clinical significance of perioperative changes of serum IL-10 level in patients with benign and malignant pulmonary diseases. Methods: Serum IL-10 levels in patients with benign (n=17) and malignant (n=25) pulmonary diseases were measured before and 1, 3, 7, 14 days after operation with RIA. Values in 82 controls were also taken. Results: The preoperative levels of serum IL-10 in patients with lung cancer were significantly higher than those in other groups (p 0.05); The levels of serum IL-10 in 36.4% of all the patients with lung cancer on day 14 were higher than the upper limit of the normal value. In patients with benign lung diseases, perioperative changes were slight and non-significant. Conclusion: Serum IL-10 level is a reliable parameter for distinguishing benign lung disease from malignant ones. Defining preoperative and postoperative changes of serum IL-10 levels might be of prognostic value in patients with lung cancer

To investigate the predictive values of preoperative and postoperative serum CA19-9 levels on survival and other prognostic factors including early recurrence in patients with resectable hilar cholangiocarcinoma. In univariate analysis, increased preoperative and postoperative CA19-9 levels in the light of different cut-off points (37, 100, 150, 200, 400, 1000 U/ml) were significantly associated with poor survival outcomes, of which the cut-off point of 150 U/ml showed the strongest predictive value (both P 150 U/ml was significantly associated with lymph node metastasis (OR = 3.471, 95% CI 1.216-9.905; P = 0.020) and early recurrence (OR = 8.280, 95% CI 2.391-28.674; P = 0.001). Meanwhile, postoperative CA19-9 level > 150 U/ml was also correlated with early recurrence (OR = 4.006, 95% CI 1.107-14.459; P = 0.034). Ninety-eight patients who had undergone curative surgery for hilar cholangiocarcinoma between 1995 and 2014 in our institution were selected for the study. The correlations of preoperative and postoperative serum CA19-9 levels on the basis of different cut-off points with survival and various tumor factors were retrospectively analyzed with univariate and multivariate methods. In patients with resectable hilar cholangiocarcinoma, serum CA19-9 predict survival and early recurrence. Patients with increased preoperative and postoperative CA19-9 levels have poor survival outcomes and higher tendency of early recurrence.

Few diagnostic biomarkers for sepsis after emergency peritonitis surgery are available to clinicians, and, thus, it is important to develop new biomarkers for patients undergoing this procedure. We investigated whether serum glutamine and selenium levels could be diagnostic biomarkers of sepsis in individuals recovering from emergency peritonitis surgery. From February 2012 to March 2013, patients who had peritonitis diagnosed at the emergency department and underwent emergency surgery were screened for eligibility. Serum glutamine and selenium levels were obtained at pre-operative, post-operative and recovery time points. The average level of pre-operation serum glutamine was significantly different from that on the recovery day (0.317 ± 0.168 vs. 0.532 ± 0.155 mM, P peritonitis. We recommend including glutamine as a biomarker for sepsis severity assessment in addition to the commonly used clinical indicators.

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

Full Text Available Carcinoembryonic antigen (CEA–targeted imaging and therapeutic agents are being tested in clinical trials. If CEA overexpression in malignant tissue corresponds with elevated serum CEA, serum CEA could assist in selecting patients who may benefit from CEA-targeted agents. This study aims to assess the relationship between serum CEA and CEA expression in pancreatic (n = 20 and rectal cancer tissues (n = 35 using histopathology. According to local laboratory standards, a serum CEA >3 ng/mL was considered elevated. In pancreatic cancer patients a significant correlation between serum CEA and percentage of CEA-expressing tumor cells was observed ( P  = .04, ρ = .47. All 6 patients with homogeneous CEA expression in the tumor had a serum CEA >3 ng/mL. Most rectal cancer tissues (32/35 showed homogeneous CEA expression, independent of serum CEA levels. This study suggests that selection of pancreatic cancer patients for CEA-targeted agents via serum CEA appears adequate. For selection of rectal cancer patients, serum CEA levels are not informative.

Steroid administration during cardiopulmonary bypass is considered to improve cardiopulmonary function by modulating inflammations caused by bypass. This study was performed to compare effectiveness of preoperative and intraoperative methylprednisolone (MP) to preoperative methylprednisolone alone in post bypass inflammatory (IL-6) and anti-inflammatory (IL-10) factors. Fifty pediatric patients undergoing cardiopulmonary bypass surgery from August 2011 to 2012 in the cardiac surgery department of Imam Reza Hospital, the major center for CPB, in Mashhad, Iran were randomly assigned to receive preoperative and intraoperative MP (30 mg/kg, 4 hours before bypass and in bypass prime, number 25) or preoperative MP only (30 mg/kg, number 25). Before and after bypass, four and 24 hours after bypass, serum IL-6 and IL-10 were measured by ELISA. In both groups, no significant difference with variation of expression for IL-6 (inflammatory factor) and IL-10 (anti-inflammatory factor) in different times after bypass was observed. No significant difference in reducing post bypass inflammation between preoperative steroid treatment and combined preoperative and intraoperative steroid administration reported and they had the same effects.

The prognostic significance of preoperative serum CA125, CA19-9 and CEA in gastric carcinoma (GC) has been widely reported and is still under debate. Here, we evaluated the prognostic significance of preoperative serum CA125, CA19-9 and CEA in patients with GC. 1692 patients with GC who underwent gastrectomy were divided into the training (from January 2005 to December 2011, n = 1024) and the validation (from January 2012 to December 2013, n = 668) cohorts. Positive groups of CA125 (> 13.72 U/ml), CA19-9 (> 23.36 U/ml) and CEA (> 4.28 ng/ml) were significantly associated with more advanced clinicopathological traits and worse outcomes than that of negative groups (all P tumor size (P tumor markers (NPTM) were more accurate in prognostic prediction than TNM stage alone. Our findings suggested that elevated preoperative serum CA125, CA19-9 and CEA were associated with more advanced clinicopathological traits and less favorable outcomes. In addition, CA125 as an independent prognostic factor should be further investigated. Nomogram based on NPTM could accurately predict the prognosis of GC patients. PMID:27097114

Full Text Available Objectives: Adipose tissue, besides its main function as an energy storage depot, is currently considered an endocrine organ that secretes several self-produced cytokines. Leptin and resistin play an important role in energy homeostasis, glucose, lipid metabolism and regulation of body weight. The aim of the current study was to determine the concentration of leptin and resistin in pre-operational and post-operational periods of patients diagnosed as colorectal cancer.Materials and methods: The body mass index (BMI and values of leptin and resistin in blood at diagnosis were measured in 12 colorectal cancer patients in pre- and post-operational periods and in 12 age- and sex-matched controls. Serum leptin and resistin concentrations were measured by ELISA method.Results: Decreased leptin (1.95±0.62 ng/ml and resistin (4.32±1.83 ng/ml levels were found in pre-operational group compared with the control group (leptin: 6.12±0.82 ng/ml; resistin: 10.75±1.46 ng/ml (p0.05.Conclusion: We conclude that serum concentration of leptin and resistin may have a role in patients with colorectal cancers. Further studies are needed to investigate the possible prognostic value of leptin and resistin in clinical practice of patients with colorectal cancers.

The aim of the study was to investigate serum thymidine kinase 1 (S-TK) activity as a diagnostic and prognostic marker for patients with pancreatic ductal adenocarcinoma (PDAC). Using the sensitive TK activity assay DiviTum, preoperative serum samples from 404 PDAC, 28 chronic pancreatitis, and 25 autoimmune pancreatitis patients and 83 healthy volunteers were analyzed. The preoperative S-TK activities of 54 PDAC patients who received neoadjuvant therapy (nTx) were also compared with those of 258 PDAC patients who did not receive nTx. The preoperative S-TK activities of PDAC patients were significantly higher and discriminatory from autoimmune and chronic pancreatitis patients and control groups. The S-TK activity in PDAC patients was associated with overall survival. Patients with S-TK activity of less than 80 Du (DiviTum units)/L demonstrated median survival of 20.3 months with an estimated 18.0% 5-year survival rate; for S-TK activity of 80 Du/L or greater, median survival was 15.1 months with a 6.8% 5-year survival rate. For early-stage PDAC, these differences were even more pronounced. The S-TK activity in the nTx group was significantly higher than that in the group not receiving nTx. Pancreatic ductal adenocarcinomas reveal a significant increase in S-TK activity, which is associated with overall survival, especially in early tumor stages. Serum thymidine kinase 1 activity may be a useful parameter for monitoring nTx efficacy.

Sestamibi imaging is the most widely used preoperative localization study for patients with hyperparathyroidism. Previous reports examine the relationship between the weight and volume of excised parathyroid glands and preoperative serum calcium and parathyroid hormone (PTH) levels.The aim of this study was to examine whether these variables correlate with the results of preoperative Sestamibi scans. A retrospective review of 150 consecutive patients who underwent preoperative sestamibi imaging for primary hyperparathyroidism between 1998 and 2007 was performed. Variables studied included patient demographics, diagnostic test (sestamibi) results, operative/pathology findings and surgical outcome (normocalcaemia vs. persistent hypercalcaemia). Sestamibi scans were designated as either 'negative' (NSS) or 'positive' (PSS), where PSS correctly localized abnormal gland(s) enabling a focused neck exploration. The results of sestamibi imaging were correlated with calcium/PTH levels, weight/volume of excised glands and patient outcomes and demographics. Total excised gland weight/volume and preoperative serum calcium levels were significantly higher with PSS (all, p ≤ 0.04). Higher preoperative serum calcium levels and greater total gland weight/volume were significantly associated with successful operative outcome (presence of postoperative normocalcaemia; all, p ≤ 0.01). Factors associated with operative failure included multi-gland disease (p <≤ 0.01) and NSS (p ≤0.01). Higher diagnostic PTH levels (≥ 150 pg/mL) were associated with greater excised gland mass (p ≤ 0.05) and volume (p ≤ 0.05). Male gender was associated with higher preoperative serum calcium levels (p < 0.02). Of interest, patients with single-gland disease had significantly higher preoperative PTH levels than patients with multi-gland disease (155 vs. 109 pg/mL, p ≤ 0.05). Positive sestamibi scans are associated with heavier/larger parathyroid glands and higher preoperative serum

Nutritional status is an important factor in graft healing. Prealbumin (transthyretin) is a better nutritional marker than the widely used albumin serum level. Prealbumin serum levels were estimated in an endeavour to correlate them to graft healing and to serve as a predictor of graft healing in burn wounds. Fifty burned patients undergoing graft in the Suez Canal University Hospital Burn Unit were subjected to this cross-sectional study. Prealbumin levels were assessed on preoperative day and on the fourth postoperative day. Graft healing was considered complete when the take was 90% or more of the grafted area. The most significantly correlated factor to graft healing was serum prealbumin. Serum albumin levels were not in significant correlation with graft healing or prealbumin levels. In addition, serum prealbumin levels were significantly higher in the younger age group and significantly lower in patients with chronic diseases. Serum prealbumin level is a sensitive tool in predicting graft take in burned patients when all local conditions are favourable and optimised. Nevertheless, it seems less sensitive in the prediction of graft healing in small raw areas less than 5% of total body surface area (TBSA). (c) 2009 Elsevier Ltd and ISBI. All rights reserved.

Objectives: To assess the prognostic value of combined evaluation of preoperative CT findings and pre/postoperative serum carcinoembryonic antigen (CEA) levels for pathological stage I lung adenocarcinoma. Methods: This retrospective study included 250 consecutive patients who underwent complete resection for ≤3-cm pathological stage I (T1–2aN0M0) adenocarcinomas (132 men, 118 women; mean age, 67.8 years). Radiologists evaluated following CT findings: maximum tumor diameter, percentage of solid component (%solid), air bronchogram, spiculation, adjacency of bullae or interstitial pneumonia (IP) around the tumor, notch, and pleural indent. These CT findings, pre/postoperative CEA levels, age, gender, and Brinkman index were assessed by Cox proportional hazards model to determine the best prognostic model. Prognostic accuracy was examined using the area under the receiver operating characteristic curve (AUC). Results: Median follow-up period was 73.2 months. In multivariate analysis, high %solid, adjacency of bullae or IP around the tumor, and high postoperative CEA levels comprised the best combination for predicting recurrence (P < 0.05). A combination of these three findings had a greater accuracy in predicting 5-year disease-free survival than did %solid alone (AUC = 0.853 versus 0.792; P = 0.023), with a sensitivity of 85.7% and a specificity of 74.3% at the optimal threshold. The best cut-off values of %solid and postoperative CEA levels for predicting high-risk patients were ≥48% and ≥3.7 ng/mL, respectively. Conclusion: Compared to %solid alone, combined evaluation of %solid, adjacency of bullae or IP change around the tumor, and postoperative CEA levels improves recurrence prediction for stage I lung adenocarcinoma.

Full Text Available Background. The reduction mammaplasty has been a well-executed and known procedure in which considerable amount of fatty tissue is removed from the body. The authors aimed to show the effects of the reduction mammaplasty on serum leptin levels and insulin resistance. Methods. 42 obese female patients who had gigantomastia were operated on. We recorded patients’ demographic and preoperative data, including age, weight, height, and body mass index. Fasting serum leptin, glucose, and insulin levels were noted. Homeostasis model assessment scores were calculated. At the postoperative 8th week, patients were reevaluated in terms of above parameters assessing the presence of any difference. Results. Serum leptin levels were decreased postoperatively and the decrease was statistically significant. We were able to show a decrease in homeostasis model assessment score, which indicated an increase in insulin sensitivity, and this change was statistically significant. A significant correlation between body mass index and leptin change was found postoperatively. Conclusion. Reduction mammaplasty is not solely an aesthetic procedure but it decreases serum leptin levels and increases insulin sensitivity, which may help obese women to reduce their cardiovascular risk.

Objective: To study the changes of serum contents of cortisol and ACTH after operation. Methods: Serum cortisol and ACTH levels were measured with RIA both before and ld, 3d post-operatively in 30 patients after Grade III operation and 15 patients after Grade IV operation. Results: On the first post-operative day, the serum cortisol and ACTH levels in both groups of patients were significantly higher than their respective pre-operative levels. Levels in Grade IV group were significantly higher than those in Grade III group. On the third post-operative day, the serum cortisol levels dropped markedly and were lower than their respective pre-operative levels. However, the serum ACTH levels continued to rise in both groups and were significantly higher than the respective levels pre-operatively as well as those on dl. The ACTH levels in the two groups were not significantly different on d3. Conclusion: Serum cortisol and ACTH levels increased in the early post-operative phase and the degree of increase of cortisol was correlated with the magnitude of the operation. (authors)

Patients with endometriosis rarely have a serum CA 125 concentration >100 IU/mL. A raised plasma level of D-dimer indicates active fibrinolysis, either secondary to clot formation or primarily activated. This condition is seldom diagnosed in patients with endometriosis. A 53-year-old woman was referred to our institution for acute abdominal pain. Laparoscopic surgery revealed a large ovarian cyst with rupture on the left side. Preoperative laboratory tests detected high serum CA 125 and D-dimer levels. Adnexectomy was performed, resulting in a sharp decrease in serum CA 125 and D-dimer concentration. We describe the clinical course of the patient. Rupture of a large ovarian endometrioma can lead to a high serum concentration of CA 125, a condition which, in addition to the detected pelvic mass, may mimic a malignant process. The increased D-dimer plasma level indicated that a ruptured endometriotic cyst can induce coagulation reactions.

Serum testosterone deficiency increases with aging. Age is also a major risk factor for prostate cancer (PrCa) and PCa tumors are more frequently diagnosed among men >65 years old. We evaluated the relationship between preoperative serum testosterone and clinical/ pathological features of PrCa in middle-aged and elderly patients. A total of 605 PrCa patients who underwent robotic-assisted radical prostatectomy between September 2010 and January 2013 at the University of Pennsylvania, and who had serum testosterone levels measured using Elecsys Testosterone II Immunoassay were included in this IRB-approved protocol. Androgen deficiency was determined as serum free testosterone (FT) men with low vs. normal TT or FT were compared using t-test or chi-square tests. Logistic regression was used to determine associations of clinical and pathological variables with FT or TT levels. Among middle-aged men (45-64 years; n = 367), those with low FT and low TT had, on average, a higher BMI (29.7 vs. 27.4, P men with normal FT and normal TT values. Patients with low FT had also higher number of positive cores on biopsy (3.9 vs. 3.1 P = 0.019) and greater tumor volume (7.9 ml vs. 6.1 ml, P = 0.045) compared to those with normal FT. Among men ≥65 years ( n = 135) there was no difference in prostatectomy specimens of PrCa between patients with low or normal FT or TT. Among men aged 45-64 years low serum pretreatment FT and TT predicted more aggressive features of PrCa in prostatectomy specimens. In middle-aged patients low testosterone levels measured pre-operatively may indicate more aggressive disease parameters.

Full Text Available Objective: Preoperative anxiety is a prevalent concern with negative effects on perioperative period but is usually ignored. The objectives of this study are to identify the preoperative anxiety levels of surgical patients and to evaluate the associated factors affecting this level. Methods: One hundred volunteer patients scheduled for elective surgery were included the study. Data were collected by using “Personal Information Form “and “State-Trait Anxiety Inventory-I”. Evaluations were based on a significance level of p<0.05. Results: The percentage of female to male patients was 48% and 52%. The mean anxiety levels of both gender were 42.46 ± 8.95 and 42.10 ± 9.49 respectively (p=0.85. There was no difference between females and males in terms of anxiety. Age, occupational condition, marital status, and education level was not found as determinant factors on preoperative anxiety levels. Male individuals of large families were more anxious than the others, but this difference was not significant (p=0.11. Previous surgical experience was not a predictive factor for preoperative anxiety. The anxiety level was significantly high in men using cigarette and alcohol (p<0.01. Fear, apprehension, and stress was highly related with high level of anxiety, but insecurity and inexperience were not a predicting factor. The anxiety levels of cool patients were significantly lower than the others (p<0.01. Conclusions: Preoperative anxiety is a multifactorial issue and must be good handled. The aim must be based on reduction strategies. It must be considered that preoperative information is the best way to decrease preoperative anxiety.

This study was to evaluate the prognostic significance of serum lipids in esophageal squamous cell carcinoma patients who underwent esophagectomy. Preoperative serum lipids were collected from 214 patients who were diagnosed with esophageal squamous cell carcinoma. All of the patients received esophagectomy in Qilu Hospital of Shandong University from January 2007 to December 2008. The records and data were analyzed retrospectively. We found that low total cholesterol (for T stage, p = 0.006; for TNM stage, p = 0.039) and low-density lipoprotein cholesterol (for T stage, p = 0.031; for TNM stage, p = 0.035) were associated with advanced T stage and TNM stage. Kaplan-Meier survival analysis indicated that low total cholesterol and low-density lipoprotein cholesterol were associated with shorter disease-free survival(for total cholesterol, p = 0.045; for low-density lipoprotein cholesterol, p squamous cell carcinoma patients who underwent esophagectomy. LHR can serve as a promising serum lipids-based prognostic indicator.

Despite limited indications, preoperative stress testing is often used prior to non-cardiac surgery. Patient-level analyses of stress testing and outcomes are limited by case mix and selection bias. Therefore, we sought to describe facility-level rates of preoperative stress testing for non-cardiac surgery, and to determine the association between facility-level preoperative stress testing and postoperative major adverse cardiac events (MACE). We identified patients undergoing non-cardiac surgery within 2 years of percutaneous coronary intervention in the Veterans Affairs (VA) Health Care System, from 2004 to 2011, facility-level rates of preoperative stress testing and postoperative MACE (death, myocardial infarction (MI) or revascularisation within 30 days). We determined risk-standardised facility-level rates of stress testing and postoperative MACE, and the relationship between facility-level preoperative stress testing and postoperative MACE. Among 29 937 patients undergoing non-cardiac surgery at 131 VA facilities, the median facility rate of preoperative stress testing was 13.2% (IQR 9.7%-15.9%; range 6.0%-21.5%), and 30-day postoperative MACE was 4.0% (IQR 2.4%-5.4%). After risk standardisation, the median facility-level rate of stress testing was 12.7% (IQR 8.4%-17.4%) and postoperative MACE was 3.8% (IQR 2.3%-5.6%). There was no correlation between risk-standardised stress testing and composite MACE at the facility level (r=0.022, p=0.81), or with individual outcomes of death, MI or revascularisation. In a national cohort of veterans undergoing non-cardiac surgery, we observed substantial variation in facility-level rates of preoperative stress testing. Facilities with higher rates of preoperative stress testing were not associated with better postoperative outcomes. These findings suggest an opportunity to reduce variation in preoperative stress testing without sacrificing patient outcomes. © Article author(s) (or their employer(s) unless otherwise

Allograft rejection is an important cause of early and long-term graft loss in kidney transplant recipients. Tumor necrosis factor-alpha promotes T-cell activation, the key reaction leading to allograft rejection. Here, we investigated whether serum and urinary tumor necrosis factor-alpha levels can predict allograft rejection. This study included 65 living related-donor renal transplant recipients with mean follow-up of 26 ± 9 months. Serum and urinary tumor necrosis factor-alpha levels were measured at pretransplant and at posttransplant time points (days 1 and 7 and months 3 and 6); serum creatinine levels were also monitored during posttransplant follow-up. Standard enzyme-linked immunoabsorbent assay was used to detect tumor necrosis factor-alpha levels. Clinical variables were monitored. Nine of 65 patients (13.8%) had biopsy-proven rejection during follow-up. Preoperative serum and urinary tumor necrosis factor-alpha levels were not significantly different when we compared patients with and without rejection. Serum tumor necrosis factor-alpha levels (in pg/mL) were significantly higher in the allograft rejection versus nonrejection group at day 7 (11.5 ± 4.7 vs 15.4 ± 5.8; P = .029) and month 1 (11.1 ± 4.8 vs 17.8 ± 10.9; P =.003). Urinary tumor necrosis factor-alpha levels (in pg/mL) were also elevated in the allograft rejection versus the nonrejection group at days 1 (10.2 ± 2.5 vs 14.1 ± 6.8; P = .002) and 7 (9.8 ± 2.2 vs 14.5 ± 2.7; P tumor necrosis factor-alpha has a role in diagnosing renal transplant rejection. Serum and urinary tumor necrosis factor-alpha levels may be a possible predictor for allograft rejection.

The aim of this study was to analyse whether the level of tissue inhibitor of metalloproteinases (TIMP) 1 is associated with the tumour response and survival to preoperative radiochemotherapy in rectal cancer patients. Ninety-two patients with histologically confirmed non-metastatic rectal cancer of clinical stage I– III were treated with preoperative radiochemotherapy, surgery and postoperative chemotherapy. Plasma TIMP-1 concentrations were measured prior to the start of the treatment with an enzyme-linked immunosorbent assay (ELISA). Median follow-up time was 68 months (range: 3–93 months) while in survivors it was 80 months (range: 68–93 months). The 5-year locoregional control (LRC), disease-free survival (DFS), disease-specific survival (DSS) and overall survival (OS) rates for all patients were 80.2%, 56.4%, 63.7% and 52.2%, respectively. The median TIMP-1 level was 185 ng/mL (range: 22–523 ng/mL) and the mean level (±standard deviation) was 192 (±87) ng/mL. Serum TIMP-1 levels were found to be significantly increased in patients with preoperative CRP>12 mg/L and in those who died from rectal cancer or had cT4 tumours. No correlation was established for age, gender, carcinoembriogenic antigene (CEA) level, platelets count, histopathological grade, response to preoperative therapy, resectability and disease reappearance. On univariate analysis, various parameters favourably influenced one or more survival endpoints: TIMP-1 <170 ng/mL, CRP <12 mg/L, platelets count <290 10E9/L, CEA <3.4mg/L, age <69 years, male gender, early stage disease (cN0 and/or cT2–3), radical surgery (R0) and response to preoperative radiochemotherapy. In multivariate model, LRC was favourably influenced by N-downstage, DFS by lower CRP and N-downstage, DSS by lower CRP and N-downstage and OS by lower TIMP-1 level, lower CRP and N-downstage. Although we did not find any association between pretreatment serum TIMP-1 levels and primary tumour response to preoperative

Background The predictive and prognostic value of carcinoembryonic antigen (CEA), cytokeratin-19 fragments (Cyfra21-1), squamous cell carcinoma antigen (SCCA) and neuron-specific enolase (NSE) has been investigated in non-small-cell lung cancer (NSCLC) patients. However, few studies have directly focused on the association between these markers and epidermal growth factor receptor (EGFR) mutation status or mutation subtypes. Patients and methods We retrospectively analyzed 1016 patients with stage I-IIIA NSCLC who underwent complete resection between 2008 and 2012. Correlations between serum tumor marker levels and EGFR mutations and survival parameters were analyzed and prognostic factors were identified. Results Cyfra21-1 levels (P = 0.032 for disease-free survival [DFS]; P CEA levels (P CEA (P = 0.005) and clinical stage were predictive factors of DFS, while elevated CEA (P = 0.005) and Cyfra21-1 (P = 0.027) were independent prognostic factors. Conclusion Cyfra21-1 and CEA exhibit different predictive and prognostic values between EGFR-mutated and wild-type adenocarcinomas, as well as between EGFR mutation subtypes. The prognostic impact of preoperative serum tumor markers should be evaluated together with EGFR mutation status. PMID:27072585

Elevated preoperative levels of alkaline phosphatase (ALP) in patients with refractory secondary hyperparathyroidism are correlated with postoperative hypocalcemia and mortality. The aim of this study was to identify the predictors of preoperative ALP in patients with secondary hyperparathyroidism. From April 2012 to December 2015, 220 patients with refractory secondary hyperparathyroidism undergoing total parathyroidectomy without autotransplantation were reviewed. A total of 164 patients presented with elevated preoperative ALP. Univariate analysis showed that patients with elevated ALP were significantly younger. The elevated ALP group had significantly higher levels of preoperative parathyroid hormone (PTH), lower preoperative serum calcium, higher preoperative phosphorus, lower postoperative hypocalcemia, and a longer hospital stay. Logistic regression analysis showed that elevated preoperative PTH was a significant independent risk factor for elevated preoperative ALP (P = 0.000), and its value of 1624 pg/mL was the optimal cutoff point. Factors predictive of elevated preoperative ALP in patients with secondary hyperparathyroidism include preoperative PTH. Earlier surgery, aggressive calcium supplementation, and more careful or aggressive postoperative care for high-risk patients are needed.

To determine the impact of preoperative serum creatinine level in non-dialyzable patients on postoperative morbidity and mortality. This is a prospective study, where serum creatinine was used to give primary assessment on renal function status preoperatively. This study includes 1,033 patients, who underwent coronary artery bypass grafting, or valve(s) operations. The study took place at Al-Hada Military Hospital, Taif, Kingdom of Saudi between May 2008 and January 2012. Data were statistically analyzed using Chi square (x2) test and multivariable logistic regression, to evaluate the postoperative morbidity and mortality risks associated with low serum creatinine levels. Postoperative mortality increased with high serum creatinine level >1.8 mg/dL (pcreatinine level of more than 1.8 mg/dL was associated with increased risk of re-operation for bleeding, postoperative renal failure, prolonged ventilatory support, ICU stay, and total hospital stay. Perioperative serum creatinine is strongly related to post operative morbidity and mortality in open heart surgery. High serum creatinine in non-dialyzable patients can predict the increased morbidity and mortality after cardiac operations.

This study was designed to investigate the efficiency of preoperative serum carcinoembryonic antigen (CEA) and carbohydrate cancer antigen (CA19-9) levels for diagnosing synchronous liver metastases and lymph node in colorectal carcinoma (CRC) patients. A total of 300 patients with histologically diagnosed CRC were included in this study between May 2014 and March 2015. The data were obtained prospectively from patient's medical records: medical history, demographics, tumor location, differentiation (grade), depth of the tumor (T), lymph node metastases (N), distant metastases (M), lymphatics, venous and perineural invasion, and disease stage. Tumor markers were measured with an electrochemiluminescent assay and the reference value was 5ng/ml for CEA and for Ca19-9, 37u/ml. There was A high statistically significant difference in the levels of serum CEA and CA19-9 between different disease stages of CRC (PCEA (stage I 3.76±8.73; II 5.68±17.27, III 7.56±14.81, and IV 70.90±253.23) and CA 19-9 levels (stage I 9.65±11.03, II 9.83±11.09; III 19.58±36.91, and IV 228.9±985.38, respectively). The mean CEA and CA19-9 serum levels were significantly higher in patients with regional lymph nodes involvement (CEA 37.21±177.85 vs 4.79±9.90, CA19-9 119.51±687.71 VS 12.24±17.69, respectively, PCEA 86.56±277.65 vs. 5.98±12.98, and CA19-9 273.27±1073.46 vs. 4.98±3142, respectively, with PCEA and CA 19-9, 3.5 ng/mL and 7.5 U/mL, respectively. While, a cut-off value for the presence of synchronous liver metastases of these two markers was 3.5ng/mL AND 5.5 U/mL. Our study showed that tumor makers, CEA and CA19-9, can be used as diagnostic factors regarding the severity of CRC specifically to suggest metastatic disease in CRC.

The transmembrane glycoprotein CA 15-3 is the most widely used serum tumor marker in breast cancer. At present the main uses of CA 15-3 are in pre-clinically detecting recurrent breast cancer and monitoring the treatment of patients with advanced breast cancer. The aim of this study was to define the role of preoperative concentrations of serum CA 15-3a sp rognostic factor and to determine its sensitivity. Serum and plasma samples from breast cancer patients and normal individuals under fasting condition were used to estimate CAlS-3 and lipid profile. The lipid profile was done in order to assess the impact of plasma lipid on the progression of breast cancer. The serum concentration of the tumor marker CAlS-3 in preoperative breast cancer patients was found to be significantly higher (p<0.001) as compared to the normal individuals. The plasma cholesterol (TC), triglyceride (TRG) and total lipid (TL) levels in breast cancer patients were found to be significantly higher (p< O.OI) for TC, TRG and TL as compared to the normal individuals. Moreover, plasma LDL-C levels in breast cancer patients were found to be significantly higher (p< O.OI) compared to the normal individuals. (author)

2015-01-01

Full Text Available Cervical and intracranial angioplasty and stenting is an effective and safe method of reducing the risk of ischemic stroke, but it may be affected by in-stent restenosis. The present study investigated serum level of matrix metalloproteinase 9 as a predictor of restenosis after 40 patients underwent cervical and/or intracranial angioplasty and stenting. Results showed that restenosis occurred in 30% (3/10 of patients when the serum level of matrix metalloproteinase 9 at 3 days after surgery was 2.5 times higher than preoperative level. No restenosis occurred when the serum level of matrix metalloproteinase 9 at 3 days after surgery was not 2.5 times higher than preoperative level. Restenosis occurred in 12% (2/17 of patients when the serum level of matrix metalloproteinase 9 was higher than preoperative level for more than 30 days after surgery, but only occurred in 4% (1/23 of patients when the serum level of matrix metalloproteinase 9 was higher than preoperative level for less than 30 days after surgery. However, the differences observed were not statistically significant (P > 0.05. Experimental findings indicate that when the serum level of matrix metalloproteinase 9 is 2.5 times higher than preoperative level at 3 days after cervical and intracranial angioplasty and stenting, it may serve as a predictor of in-stent restenosis.

Hypoalbuminemia may increase the risk of acute kidney injury (AKI). The authors investigated whether the immediate preoperative administration of 20% albumin solution affects the incidence of AKI after off-pump coronary artery bypass surgery. In this prospective, single-center, randomized, parallel-arm double-blind trial, 220 patients with preoperative serum albumin levels less than 4.0 g/dl were administered 100, 200, or 300 ml of 20% human albumin according to the preoperative serum albumin level (3.5 to 3.9, 3.0 to 3.4, or less than 3.0 g/dl, respectively) or with an equal volume of saline before surgery. The primary outcome measure was AKI incidence after surgery. Postoperative AKI was defined by maximal AKI Network criteria based on creatinine changes. Patient characteristics and perioperative data except urine output during surgery were similar between the two groups studied, the albumin group and the control group. Urine output (median [interquartile range]) during surgery was higher in the albumin group (550 ml [315 to 980]) than in the control group (370 ml [230 to 670]; P = 0.006). The incidence of postoperative AKI in the albumin group was lower than that in the control group (14 [13.7%] vs. 26 [25.7%]; P = 0.048). There were no significant between-group differences in severe AKI, including renal replacement therapy, 30-day mortality, and other clinical outcomes. There were no significant adverse events. Administration of 20% exogenous albumin immediately before surgery increases urine output during surgery and reduces the risk of AKI after off-pump coronary artery bypass surgery in patients with a preoperative serum albumin level of less than 4.0 g/dl.

Full Text Available Background: A deficiency of magnesium is of clinical importance in hospitalized patients. The prevalence of hypomagnesaemia is high in critically ill patients. Knowing the important role of magnesium in surgical cases, it is necessary to anticipate and diagnose magnesium deficiency prior to surgery and in the immediate postoperative period to correct it. Aims and Objectives: The aim of this study was to analyse serum magnesium levels in patients undergoing emergency surgical procedures, planned surgical procedures and normal healthy matched controls and to compare the serum magnesium levels in all the three groups. Materials and Methods: The study participants were divided into three groups: i Group I: patients undergoing emergency major surgery ii Group II: patients undergoing planned major surgery iii Group III: normal healthy controls. Serum Magnesium investigation was done by Xylidyl Blue Method using UV-1800/Shimadzu UV-Spectrophotometer. Results: The mean serum Magnesium in control group was found to be 2.16 ± 0.30 mg/dl. In patients undergoing planned surgery, pre-operative serum magnesium was normal (2.16 ± 0.22 mg/dl but decreased significantly on postoperative day 3 (1.63 ± 0.27 mg/dl and day 6 (1.97 ± 0.12 mg/dl and returned to normal level by post-operative day 9 (2.14 ± 0.14 mg/dl compared to controls. In patients undergoing emergency surgery, serum magnesium was decreased pre-operatively (1.90 ± 0.48 mg/dl.Further significant reduction was found at post-operative day 3 (1.38 ± 0.28 mg/dl, day 6 (1.59 ± 0.30 mg/dl and day 9 (1.88 ± 0.46 mg/dl compared to controls. Mean serum Magnesium overall in emergency surgery patients was reduced significantly compared to planned surgery patients. Conclusion: A transient fall in the serum Magnesium as compared to its pre-operative level was seen in every patient undergoing surgical procedure due to surgical stress. In patients undergoing emergency surgical procedure, the decrease was

Serum albumin has traditionally been used as a quantitative measure of a patient’s nutritional status because of its availability and low cost. While malnutrition has a clear definition within both the American and European Societies for Parenteral and Enteral Nutrition clinical guidelines, individual surgeons often determine nutritional status anecdotally. Preoperative albumin level has been shown to be the best predictor of mortality after colorectal cancer surgery. Specifically in colorect...

It is known that bone mineral density and serum magnesium levels are low in malnourished children. However, the roles of serum magnesium and endothelin-1 (ET-1) levels in the pathophysiology of bone mineralization are obscure. Thus, the relationships between serum magnesium and ET-1 levels and the changes in bone mineral density were investigated in this study. There was a total of 32 subjects, 25 of them had PEM and seven were controls. While mean serum ET-1 levels of the children with kwashiorkor and marasmus showed no statistically significant difference, mean serum ET-1 levels of both groups were significantly higher than that of the control group. Serum magnesium levels were lower than normal value in 9 (36%) of 25 malnourished children. Malnourished children included in this study were divided into two subgroups according to their serum magnesium levels. While mean serum ET-1 levels in the group with low magnesium levels were significantly higher than that of the group with normal magnesium levels (p malnutrition. Our study suggested that lower magnesium levels and higher ET-1 levels might be important factors in changes of bone mineral density in malnutrition. We recommend that the malnourished patients, especially with hypomagnesaemia, should be treated with magnesium early.

The effect of the histamine-2 receptor antagonist ranitidine (100 mg intravenously every 12 hours for 72 hours) on postoperative serum antibody responses to preoperative immunization with six limit of flocculation tetanus toxoid and six limit of flocculation diphtheria toxoid was assessed...... in a double-blind, placebo-controlled randomized study in 26 patients undergoing major abdominal surgery. The preoperative antitetanus antibody level was less than 0.1 IU/ml in all patients, and they were inoculated with both antigens 48 hours before surgery. Serum samples for analysis of antitetanus toxoid...... and antidiphtheria toxoid were drawn before skin incision and on postoperative days 1, 3, 5, 7, 10, 14, 21, and 28. Ranitidine significantly increased the postoperative antibody response to tetanus toxoid, (p less than 0.01) and insignificantly increased that to diphtheria toxoid vaccination (p less than 0...

Systemic Sclerosis (SSc) is a systemic connective tissue disease. In this study, we compared the serum Homocystein (Hcy) level between patients with SSc and normal control group. The current study was conducted to determine whether serum Hcy levels are elevated in SSc patients and whether there is any correlation between Hcy levels and RP, Gastro intestinal and lung involvement. Forty one patients who fulfilled the diagnostic criteria for SSc (39 females and 5 males) and Forty four community-based healthy individuals (sex and age matched) were enrolled in to the study. Serum Hcy, vitamin B12, and folate levels were determined. Thirty three patients (70.45%) had GI involvement, twenty two patients (50%) had lung involvement and twenty seven patients (61.36%) had Raynaud's phenomena. Mean serum Hcy level in control group was 22.78 ± 6.018 μmol/L and in case group was 19.43 ± 7.205 μmol/L, shows that the serum Hcy level in control group was significantly higher than patients (P = 0.020). Serum Hcy level is significantly lower in SSc patients than in control group. There is no statistically significant correlation between serum Hcy level and organ involvements.

Open surgical repair (OSR) is a conventional surgical method used in the repair a ruptured abdominal aortic aneurysm (AAA); however, OSR results in high perioperative mortality rates. The level of serum angiotensin-converting enzyme 2 (ACE2) has been reported to be an independent risk factor for postoperative in-hospital mortality following major cardiopulmonary surgery. In the present study, the association of serum ACE2 levels with postoperative in-hospital mortality was investigated in patients undergoing OSR for ruptured AAA. The study enrolled 84 consecutive patients underwent OSR for ruptured AAA and were subsequently treated in the intensive care unit. Patients who succumbed postoperatively during hospitalization were defined as non-survivors. Serum ACE2 levels were measured in all patients prior to and following the surgery using ELISA kits. The results indicated that non-survivors showed significantly lower mean preoperative and postoperative serum ACE2 levels when compared with those in survivors. Multivariate logistic regression analysis also showed that, subsequent to adjusting for potential confounders, the serum ACE2 level on preoperative day 1 showed a significant negative association with the postoperative in-hospital mortality. This was confirmed by multivariate hazard ratio analysis, which showed that, subsequent to adjusting for the various potential confounders, the risk of postoperative in-hospital mortality remained significantly higher in the two lowest serum ACE2 level quartiles compared with that in the highest quartile on preoperative day 1. In conclusion, the present study provided the first evidence supporting that the serum ACE2 level is an independent risk factor for the in-hospital mortality following OSR for ruptured AAA. Furthermore, low serum ACE2 levels on preoperative day 1 were found to be associated with increased postoperative in-hospital mortality. Therefore, the serum ACE2 level on preoperative day 1 may be a potential

Full Text Available Secondary hyperparathyroidism (SHPT is a common, important, and treatable complication of end-stage renal disease. This study was conducted to investigate the role of serum magnesium (Mg in regulating the secretion of parathyroid hormone (PTH by the parathyroid gland in patients on maintenance hemodialysis (HD. Pre-dialysis serum levels of calcium (Ca, phosphorus (P, Mg, alkaline phosphatase (ALP, intact serum PTH (iPTH, serum 25-hydroxy Vitamin D (25-OH Vit D and plasma bicarbonate (HCO3 were measured. The Urea Reduction Rate as well as duration and dosage of HD treatment were noted. Our study did not show any significant correlation between serum Mg levels and duration of HD treatment, levels of serum ALP, and plasma HCO3, Ca and P. An inverse correlation, albeit insignificant, was found between the serum Mg levels and iPTH (r=-0.30 p=0.079; also, a significant positive correlation was found between serum Mg levels and serum 25-OH Vit D levels (r= 0.40 p= 0.009. Our findings are in agreement with previous data, which suggest that factors other than serum Mg are more important in the regulation of PTH secretion in HD patients. A positive and strong association between serum Mg with 25-OH Vit D needs to be studied in greater detail.

Full Text Available Abstract Background There is an insufficient number of reliable prognostic and response predictive biomarkers in colorectal cancer (CRC management. In a previous study, we found that high tumour tissue expression of tumour-associated trypsin inhibitor (TATI correlated with liver metastasis and an impaired prognosis in CRC. The aim of this study was to investigate the prognostic validity of serum TATI (s-TATI in CRC. We further assessed the prognostic value of carcino-embryonic antigen in serum (s-CEA and the interrelationship between s-TATI and TATI in tissue (t-TATI. Methods Using an immunofluorometric assay, s-TATI levels were analysed in 334 preoperatively collected serum samples from patients with CRC. Spearman's Rho and Chi-square test were used for analysis of correlations between s-TATI and clinicopathological parameters, s-CEA and t-TATI. Kaplan-Meier analysis and Cox uni- and multivariate regression analysis were used to estimate disease free survival (DFS and overall survival (OS according to quartiles of s-TATI and cut-offs derived from ROC-analysis of s-TATI and s-CEA. Results Increased levels of s-TATI were associated with a reduced DFS (HR = 2.00; 95% CI 1.40-2.84, P P P = 0.034 for DFS and HR = 1.78; 95% CI 1.25-2.53, P = 0.001 for OS. There was no significant association between s-TATI and t-TATI. The prognostic value of s-CEA was also evident, but somewhat weaker than for s-TATI. Conclusions High preoperative s-TATI levels predict a poor prognosis in patients with CRC, and the prognostic value is independent of established prognostic parameters and t-TATI expression. These data suggest that s-TATI might be a useful marker for prognostic stratification in CRC.

Abstract Follistatin is a glycoprotein with various biologic functions that plays a role in adipocyte differentiation, muscle stimulation, anti-inflammation, and energy homeostasis. Thyroid hormones influence energy expenditure, glucose, and lipid metabolism. The association between serum follistatin level and thyroid function statuses has seldom been evaluated. The objectives of this study were to compare serum follistatin concentrations in different thyroid function statuses and to evaluate the associations between serum follistatin and free thyroxine (fT4) levels. In this study, 30 patients with hyperthyroidism (HY group) and 30 euthyroid individuals (EU group) were recruited. The patients of HY group were treated with antithyroid regimens as clinically indicated, whereas no medication was given to EU group. The demographic and anthropometric characteristics, biochemical data, serum levels of follistatin, and thyroid function of both groups at baseline and at the 6th month were compared. Data of all patients were pooled for the analysis of the associations between the levels of follistatin and fT4. At baseline, the HY group had significantly higher serum follistatin levels than the EU group (median [Q1, Q3]: 1.81 [1.33, 2.78] vs 1.13 [0.39, 1.45] ng/mL, P hyperthyroidism had higher serum follistatin levels, which decreased after receiving antithyroid treatment. In addition, the serum follistatin concentrations were positively associated with serum fT4 levels in patients with hyperthyroidism or euthyroidism. PMID:26844494

The immunologic status of kidney allograft recipients affects transplant outcome. High levels of pretransplant serum soluble CD30 correlate with an increased risk of acute rejection. Studies show conflicting results. We evaluated the relation between pretransplant serum sCD30 levels with the risk of posttransplant acute kidney rejection in renal transplant recipients. This prospective cohort study was performed between March 2010 and March 2011 on 77 kidney transplant recipients (53 men [68.8%], 24 women [31.2%]; mean age, 41 ± 14 y). Serum samples were collected 24 hours before transplant and analyzed for soluble CD30 levels by enzyme-linked immunosorbent assay. Patients were followed for 6 months after transplant. Acute biopsy-proven rejection episodes were recorded, serum creatinine levels were measured, and glomerular filtration rates were calculated at the first and sixth months after transplant. Preoperative serum soluble CD30 levels were compared in patients with and without rejection. The mean pretransplant serum soluble CD30 level was 92.1 ± 47.3 ng/mL. At 6 months' follow-up, 10 patients experienced acute rejection. Mean pretransplant soluble CD30 levels were 128.5 ± 84 ng/mL versus 86.7 ± 37 ng/mL in patients with and without acute rejection episodes (P = .008). At 100 ng/mL, the sensitivity, specificity, and positive and negative predictive values of pretransplant serum soluble CD30 level to predict acute rejection were 70%, 73.6%, 29.1%, and 94.3%. We showed a significant relation between pretransplant serum soluble CD30 levels and acute allograft rejection. High pretransplant levels of serum soluble CD30 can be a risk factor for kidney transplant rejection, and its high negative predictive value at various cutoffs make it useful to find candidates with a low risk of acute rejection after transplant.

Full Text Available Often, pathological Gleason Score (GS and stage of prostate cancer (PCa were inconsistent with biopsy GS and clinical stage. However, there were no widely accepted methods predicting upgrading and upstaging PCa. In our study, we investigated the association between serum testosterone and upgrading or upstaging of PCa after radical prostatectomy (RP. We enrolled 167 patients with PCa with biopsy GS ≤6, clinical stage ≤T2c, and prostate-specific antigen (PSA <10 ng ml−1 from April 2009 to April 2015. Data including age, body mass index, preoperative PSA level, comorbidity, clinical presentation, and preoperative serum total testosterone level were collected. Upgrading occurred in 62 (37.1% patients, and upstaging occurred in 73 (43.7% patients. Preoperative testosterone was lower in the upgrading than nonupgrading group (3.72 vs 4.56, P< 0.01. Patients in the upstaging group had lower preoperative testosterone than those in the nonupstaging group (3.84 vs 4.57, P= 0.01. In multivariate logistic regression analysis, as both continuous and categorical variables, low serum testosterone was confirmed to be an independent predictor of pathological upgrading (P = 0.01 and P= 0.01 and upstaging (P = 0.01 and P = 0.02 after RP. We suggest that low serum testosterone (<3 ng ml−1 is associated with a high rate of upgrading and upstaging after RP. It is better for surgeons to ensure close monitoring of PSA levels and imaging examination when selecting non-RP treatment, to be cautious in proceeding with nerve-sparing surgery, and to be enthusiastic in performing extended lymph node dissection when selecting RP treatment for patients with low serum testosterone.

Full Text Available Endocan is an endotelial cell specific molecule; previous studies have shown that serum endocan levels increased in cancer and sepsis and are also related to the severity of sepsis. There are no clinical study about serum endocan levels in children with febrile neutropenia. The aim of this study was to evaluate serum endocan levels in pediatric leukemia patients with febrile neutropenia (n=33 and compare them with children with leukemia without fever (n=33 and also with healthy children (n=24. The median serum endocan level in the first group (children with febrile neutropenia was statistically significantly higher compared to the leukemic children without febrile neutropenia and also control group (P<0.01 for both. No difference was determined between the serum endocan levels of the leukaemia patients without febrile neutropenia and the healthy control group (P>0.05. Serum endocan levels were also similar with febrile neutropenia due to bacterial causes comparing with the idiopathic febril neutropenia. The results of this study showed increased serum endocan in children with leukemia during the febrile neutropenia episode, and no changes of serum endocan levels in children without leukemia without infection/fever. The monitoring of a series of serum endocan levels would be helpful for the course of febrile neutropenia.

The results of the serum levels of adiponectin in pre eclamptic patients are conflicting. Objective: The aim of the present study was to assess serum levels of adiponectin in women with pre eclampsia compared with healthy pregnant women. Methods: A cross-sectional study was designed. The case group consisted of women with pre eclampsia (n=30). The control group consisted of 30 matched normal pregnant women. Serum levels of adiponectin were assessed using enzyme-linked immunosorbent assay method. Results: Serum levels of adiponectin were significantly higher in the pre eclamptic group than those in the normal control group. In the pre eclamptic patients serum levels of adiponectin showed a significant negative correlation with body mass index while no correlation was found in the normal pregnant women. In women with pre eclampsia, levels of adiponectin were decreased significantly in the overweight women compared with normal weight women, while in the control group no significant difference was observed. Conclusion: In conclusion, elevation of adiponectin levels might be a physiological feedback response to minimize endothelial dysfunction in pre eclamptic patients. (author)

Surgical staging in early-stage uterine cancer is controversial. Preoperative serum CA-125 may be of clinical value in predicting the presence of extra-uterine disease in patients with apparent early-stage endometrial cancer. Between October 6, 2005, and June 17, 2010, 760 patients were enrolled in an international, multicentre, prospective randomized trial (LACE) comparing laparotomy with laparoscopy in the management of endometrial cancer apparently confined to the uterus. Of these, 657 patients with endometrial adenocarcinoma had a preoperative serum CA-125 value recorded. Multiple cross-validation analysis was undertaken to correlate preoperative serum CA-125 with stage of disease (Stage I vs. Stage II+) after surgery. Patients' median preoperative serum CA-125 was 14 U/ml. A cutoff point of 30 U/ml was associated with the smallest misclassification error, and using this cutoff, 98 patients (14.9%) had elevated CA-125 levels. Of those, 36 (36.7%) had evidence of extra-uterine disease. Of the 116 patients (17.7%) with evidence of extra-uterine disease, 31.0% had an elevated CA-125 level. On univariate and multivariable logistic regression analysis, only preoperative CA-125 level, but no other preoperative clinical characteristics were found to be associated with extra-uterine spread of disease. Utilizing a cutoff point of 30 U/ml achieved a sensitivity, specificity, positive predictive value and negative predictive value of 31.0, 88.5, 36.7 and 85.7%, respectively. Elevated CA-125 above 30 U/ml in patients with apparent early-stage disease is a risk factor for the presence of extra-uterine disease and may assist clinicians in the management of patients with clinical Stage I endometrial cancer.

Interleukin-10 (IL-10), interleukin-17A (IL-17A) and transforming growth factor α (TGF-α) have been implicated in the progression of breast cancer. However, the diagnostic and prognostic roles of these cytokines in ductal carcinoma remain unclear. The present study therefore aimed to determine the serum levels of IL-10, IL-17 and TGF-α in subjects with benign and malignant breast diseases and to evaluate the clinical significance of these cytokines in ductal carcinoma. Pre-operative serum samples were collected from 378 patients with breast disease and 70 healthy subjects. IL-10, IL-17A and TGF-α levels were measured using ELISA. Serum levels of these cytokine in patients with different breast diseases were evaluated. Furthermore, correlations between levels of these cytokines and the expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) in ductal carcinoma were determined. The results demonstrated that serum levels of IL-10 and IL-17A were significantly increased in subjects with atypical hyperplasia and ductal carcinoma. Furthermore, IL-10 and IL-17A levels were increased in patients with a more serious clinical tumor stage and tumors that were ER - and PR - . Furthermore, high serum levels of TGF-α were associated with HER2 + tumors. A strong positive correlation was identified between TGF-α and IL-17A levels. Therefore, the results of the current study revealed that elevated serum IL-10, IL-17A and TGF-α levels are strongly associated with ductal carcinoma, specifically with tumor stage. High serum levels of IL-10 and IL-17A were also associated with the negative expression of ER and PR in ductal carcinoma, and high serum levels of TGF-α were associated with the positive expression of HER2 in ductal carcinoma. Thus, serum cytokine levels may be measured to identify patients with a poor prognosis who may benefit from more aggressive management and treatment.

Full Text Available Objective. This study assesses the role of preoperative serum CA125 levels in the planning treatment options for women diagnosed with uterine cancer. Material and Method. Ninety five consecutive patients diagnosed with uterine cancer during a four-year period were identified. Age ranged from 35 to 89 years with a mean age of 69 years. The preoperative CA125 levels were dichotomised at 28 U/mL (using ROC analysis to identify the best discriminating threshold for 5-year survival. This level was then correlated with preoperative prognostic indicators: patient age, tumour grade, and histopathological tumour cell type. Survival data was plotted using Kaplan-Meier curves and analysed using the log-rank test. Univariate and multivariate analysis were performed to identify the predictors of overall survival. Results. The mean age of patients was 69 years (range: 35–89. On univariate analysis, the use of preoperative CA125 levels of greater or less than 28 U/mL correlated significantly with age (P=0.01, the grade of disease (P=0.02 and unfavourable tissue type (P=0.03. This threshold CA125 level had a sensitivity of 75%, specificity of 76%, positive predictive value of 35% and negative predicative value of 96.25%, and a likelihood ratio of 3.12 for predicting nodal disease. Using a threshold of preoperative CA125 level of 28 U/mL (area under curve: 0.60 was also a significant predictor of 5-year survival (log-rank test, P=0.01. Using Cox multivariate survival analysis to identify predictive preoperative factors overall, unfavourable cell type was the strongest predictor of survival (Chi square = 36.5, df = 4, and P=0.001, followed by preoperative CA125 level (CA125 > 28 U/mL, P=0.011 and unfavourable preoperative grade (P=0.017. Amongst patients with a favourable histological tissue type (endometrioid, preoperative CA125 levels predicted overall survival (Chi square = 6.039, df = 2, P=0.02; however unfavourable preoperative

To clarify the alterations in serum adropin and preptin concentrations in preeclampsia, we determined serum adropin and preptin levels in 29 women with normal pregnancy and 32 women with preeclampsia. We found that maternal age, body mass index and fetal gender were not significantly different between two groups; however, blood pressure, gestational age and neonatal birth weight were significantly different. Serum adropin levels were significantly increased in women with preeclampsia compared with those with normal pregnancy but there were no significant differences in preptin levels. An increase in maternal serum adropin level was found in preeclampsia, and this may be a compensation for pregnancy complicated with preeclampsia.

A nested, matched case-control study was conducted to assess the relationship between serum levels of copper and the subsequent risk of cancer. One hundred thirty-three cases of cancer were identified during 1974-1984 among 5000 members of a northwest Washington State employee cohort from whom serum specimens had been previously obtained and stored. Two hundred forty-one controls were selected at random from the cohort and were matched to the cases on the basis of age, sex, race, and date of blood draw. Serum copper levels were measured by atomic absorption spectrometry. Risk of a subsequent diagnosis of cancer was positively associated with serum copper levels, but only among those cases diagnosed within 4 years of the time the serum specimens were collected. Among cases diagnosed more than 4 years after specimen collection, there was no consistent association between serum copper levels and risk. Adjustment for age, sex, race, occupational status, cigarette smoking, family history of cancer, alcohol consumption, and, among females, use of exogenous hormones had no appreciable effect on these relationships. The findings suggest that the presence of cancer may increase serum copper levels several years prior to its diagnosis. They are less supportive of the hypothesis that serum copper levels affect cancer risk.

Serum zinc level amongst children with protein energy malnutrition (PEM) was evaluated in a control study conducted in the Department of Paediatrics, Allama Iqbal Medical College and Jinnah Hospital, Lahore. Twenty-five children with PEM and 25 healthy children as control from the community were screened. Mean serum zinc level was found to be 54.48 -+ 18.91 mg/dl in children with PEM while it was 72.72 -+ 8.21 mg/dl in control group (P < 0.001). No significant difference in zinc level was noted between both sexes in each group. Marasmic 16 children revealed mean serum zinc level of 57.55 -+ 18.16 mg/dl while in Kwashiorkor it was 44.57 -+ 13.66 mg/dl. Serum zinc was significantly low in Kwashiorkor than in marasmus (P < 0.001). It was also significantly low in children with acute or chronic diarrhea associated with malnutrition (44.66 -+ 16.0 mg/dl). Acute respiratory infections in these children were not associated with low serum zinc level (71.66 -+ 16.51 mg/dl). (author)

This study aimed to identify the effect of preoperative serum total cholesterol on postoperative pain outcome in patients who had undergone laparoscopic colorectal cancer surgery. We retrospectively reviewed the medical records of patients diagnosed with colorectal cancer who had undergone laparoscopic colorectal surgery from January 1, 2011, to June 30, 2017, to identify the relationship of total cholesterol levels within a month prior to surgery with the numeric rating scale (NRS) scores and total opioid consumption on postoperative days (PODs) 0-2. We included 1,944 patients. No significant correlations were observed between total cholesterol and the NRS (POD 0), NRS (POD 1), and oral morphine equivalents (PODs 0-2) ( P >0.05). There was no significant difference between the low (0.05). Furthermore, there was no significant association in multivariate linear regression analysis for postoperative opioid consumption according to preoperative serum total cholesterol level (coefficient 0.08, 95% CI -0.01 to 0.18, P =0.81). This study showed that there was no meaningful association between preoperative total cholesterol level and postoperative pain outcome after laparoscopic colorectal cancer surgery.

Full Text Available Introduction: Matrix metalloproteinases are produced by tumour cells, hence, they may be associated with tumour progression including invasion, migration, angiogenesis and metastasis. Finding prognostic markers to better identify patients with higher risk for poor survival would be valuable in order to customize pre- and postoperative treatment as well as to enable closer follow-up of these patients. Aim of our study was to examineMMP-2, MMP-7 and MMP-9 serum levels and correlated them with pathological data such as stage of the colorectal cancer (CRC and outcome.Methods: The investigation included 82 patients with operable CRC without distant metastases, who had underwent blood tests in order to determine the MMP-2, MMP-7 and MMP-9 serum levels in the following time periods: preoperatively, 3, 6, 9 and 12 months postoperatively.Results: The values of the investigated MMPs decrease postoperatively and start to increase 6 month later in patients of all stages of the disease, reaching the highest value 12 month postoperatively with statistically important differences of MMP-2, MMP-7 and MMP-7 serum levels in terms of disease staging and defined points of time. Analysis of the results showed that the MMP-2 serum levels obtained 3 and 12 months postoperatively,than MMP-7 serum levels 12 months postoperatively and the MMP-9 serum levels in all analyzed points in time were in significant association with the CRC patients’outcome.Conclusion: The MMP-2, MMP-7 and especially MMP-9 serum values could be important indicators for diagnosis of the patients with CRC and for monitoring of disease progression.

C-Reactive protein (CRP) has been associated with the macro- and microvascular effects of hypertension and diabetes mellitus. Referring to serum cortisol, it has been proposed to contribute to the pathogenesis of metabolic syndrome, and it has been demonstrated that weight loss normalizes cortisol levels and improves insulin resistance. The aims of this study were to analyze CRP and cortisol levels pre- and postoperatively in morbidly obese patients undergoing a laparoscopic sleeve gastrectomy and to correlate them with weight loss and parameters associated with cardiovascular risk. A prospective study of all the morbidly obese patients undergoing laparoscopic sleeve gastrectomy as bariatric procedure between October 2007 and May 2011 was performed. A total of 40 patients were included in the study. CRP levels decreased significantly 12 months after surgery (median reduction of 8.9 mg/l; p = 0.001). Serum cortisol levels decreased significantly 6 months after surgery (median reduction of 34.9 μg/dl; p = 0.001). CRP values reached the normal range (cortisol, a significant association was observed with the cardiovascular risk predictor (triglyceride/high-density lipoprotein cholesterol ratio) from the 6th month after surgery onward (Pearson correlation coefficient, 0.559; p = 0.008). CRP levels are increased preoperatively and in the postoperative course up to 1 year after surgery. Serum cortisol levels remain elevated until the 6th month after surgery. From this moment onward, serum cortisol is associated with the cardiovascular risk predictor reflecting the cardiovascular risk decreasement during the weight loss.

Erythropoietin (Epo) is the first well studied hemopoietic growth factor. The pathological levels of its serum concentration show deviations in the specific mechanisms for some diseases such as polycythemia. Objective of this work is the assessment of the diagnostic value of the Epo in the serum for the differentiation of the main form of polycythemia - true and symptomatic. Material and methods: 47 patients are studied (21 women and 26 men), 23 of them are with polycythemia vera and 24 with polycythemia symptomatica. The following has been determined: the serum level of Erythropoietin, hemoglobin, the number of erythrocytes, leukocytes, thrombocytes, myelogram. The serum level of Epo is quantitatively determined b using of radioimmunological method, through Epo-Trac kit. Results: The diagnosis is also confirmed in all patients by other laboratory tests. The normal values of Epo in healthy persons are 17.0±7.0 mU/ml. The average Epo level in patients with polycythemia vera is 20.4±3.0 mU/ml. In one patient the Epo level is supposedly connected with an accompanying kidney disease. Conclusions: The obtained data show that the Epo serum level is an accurate criterion in the diagnosing of true and symptomatic polycythemia. The true polycythemia is connected with an independent erythrocyte production. In the symptomatic polycythemia the tissue hypoxia stimulated the Epo production

The inflammatory reactions are stronger after surgery of malnourished preoperative patients. Many studies have shown vitamin and trace element deficiencies appear to affect the functioning of immune cells. Enteral nutrition is often inadequate for malnourished patients. Therefore, total parenteral nutrition (TPN) is considered an effective method for providing preoperative nutritional support. TPN needs a central vein catheter, and there are more risks associated with TPN. However, peripheral parenteral nutrition (PPN) often does not provide enough energy or nutrients. This study investigated the inflammatory response and prognosis for patients receiving a modified form of PPN with added fat emulsion infusion, multiple vitamins (MTV), and trace elements (TE) to assess the feasibility of preoperative nutritional support. Methods. A cross-sectional design was used to compare the influence of PPN with or without adding MTV and TE on malnourished abdominal surgery patients. Both preoperative groups received equal calories and protein, but due to the lack of micronutrients, patients in preoperative Group B exhibited higher inflammation, lower serum albumin levels, and higher anastomotic leak rates and also required prolonged hospital stays. Malnourished patients who receive micronutrient supplementation preoperatively have lower postoperative inflammatory responses and better prognoses. PPN with added fat emulsion, MTV, and TE provides valid and effective preoperative nutritional support.

The purpose of this study was to investigate the effects of distraction on the preoperative anxiety levels of pediatric patients. A prospective, two-group experimental design was used. This study was conducted in the clinic of pediatric surgery of a university hospital in Turkey between November 20, 2013 and January 25, 2014. The population of the study was composed of a total of 83 children (40 in the study group and 43 in the control group) who met the inclusion. The data were collected using the "Personal Information Form," "Separation Scoring," and "State-Trait Anxiety Inventory for Children-State Form." Distraction was performed on the children in the study group during the preoperative period. No intervention was applied to the children in the control group. The results of this study demonstrated that the separation scores and State-Trait Anxiety Inventory for Children-State scores of the children in the study group, on whom distraction was applied, were lower than those of the control group. Distraction applied to children in the preoperative period significantly reduced anxiety and separation anxiety. Copyright © 2016 American Society of PeriAnesthesia Nurses. Published by Elsevier Inc.

To compare serum zinc level between Thalassemia Major (TM) patients and normal population at Shafa Hospital in South West of Iran. A total of 25 male and 36 female of TM patients were enrolled in this study. Out of 61 patients thirty were treated by deferroxamine (DFO) and 31 were on the combination of DFO and deferiprone (DEF) protocol therapy. Sixty normal subjects of the matching age and gender were recruited as controls. From each patient and control group 2 ml of blood was taken in fasting condition. Cell blood count and serum zinc were carried out for both thalassemia patients and normal subjects. The mean age of patients and control group was 15+- 5 years. Mean serum zinc level was 68.97+- 21.12 mu g/dl, 78.10-28.50 mu g/dl, and 80.16+- 26.54 mu g/dl in the TM with DFO, TM with DFO + DEF combination protocol and control group respectively. There was no significant correlation between patients and control group. However 50 percent of TM with DFO, 38.7 percent of TM with DFO + DEF and 32.8 percent of control group had hypozincemia. Nearly 40 to 50 percent of TM patients and one third of normal subjects are suffering from hypozincemia. This study shows that low level of serum zinc is a health problem in both thalassemia patients and normal population in South West of Iran. (author)

Osteopontin a matricellular protein has pro-fibrotic effects and binds integrin such as αvβ1 and αvβ3. Vitronectin is one of the integrin αvβ3 ligands and is a multifunctional glycoprotein. The aim of the present study was to evaluate serum osteopontin and vitronectin levels in a cohort of patients with systemic sclerosis (SSc). Eighty-six patients with SSc, 46 patients with systemic lupus erythematosus (SLE), and 38 healthy controls (HC) were enrolled in the study. Serum osteopontin, vitronectin, IL-6, and TGF-β levels were analyzed. Serum osteopontin levels were higher in the SSc and SLE groups compared to the HC group (p < 0.01 and p < 0.001, respectively). However, it was not correlated with disease activity and severity scores in the SSc group. On the other hand, serum vitronectin levels were lower in the SSc group than in the SLE and HC groups (p < 0.001 for both). These results may suggest that osteopontin levels may be increased due to the inflammatory process and osteopontin has not a specific role on fibrosis in SSc. On the other hand, serum vitronectin levels decrease in SSc in contrast to SLE. It may be concluded that the one cause of decreased serum vitronectin levels in SSc may be its accumulation in fibrotic area.

A best evidence topic was written according to a structured protocol. The clinical question investigated was: is low serum albumin associated with postoperative complications in patients undergoing cardiac surgery? There were 62 papers retrieved using the reported search strategy. Of these, 12 publications embodied the best evidence to answer this clinical question. The authors, journal, date and country of the publication, patient group investigated, study design, relevant outcomes and results of these papers were tabulated. This paper includes a total of 12 589 patients, and of the papers reviewed, 4 were level 3 and 8 level 4. Each of the publications reviewed and compared either all or some of the following postoperative complications: mortality, postoperative bleeding requiring reoperation, prolonged hospital stay and ventilatory support, infection, liver dysfunction, delirium and acute kidney injury (AKI). Of the studies that examined postoperative mortality, all except for three established a significant multivariate association with low preoperative albumin level. Some scepticism is required in accepting other results that were only present in univariate analysis. While three studies examined multiple levels of serum albumin, most dichotomized the serum albumin levels into normal and abnormal groups. This led to differing classifications of hypoalbuminaemia, ranging from less than 2.5 to 4.0 g/dl. The available evidence, however, suggests that low preoperative serum albumin level in patients undergoing cardiac surgery is associated with the following: (i) increased risk of mortality after surgery and (ii) greater incidence of postoperative morbidity. While the evidence supports the use of preoperative albumin in assessing post-cardiac surgery complications, a specific level of albumin considered to be abnormal cannot be concluded from this review. © The Author 2015.

The aim of this study was to determine the impact of hypovitaminosis D on Gastric Bypass outcomes. We retrospectively reviewed all patients who underwent primary intention Gastric Bypass in our center between January 2012 and December 2013. Postoperative complications, 1 and 2-year excess weight loss were compared between patients with and without hypovitaminosis D. Among 258 patients who met inclusion criteria, 56 (21.7%) presented with vitamin D deficiency. Mean age was 41.73 ± 12.95 years. Mean BMI was 40.90 kg/m 2 (34-58 kg/m 2 ). No statistically significant difference in postoperative complication rate was found between patients with and without hypovitaminosis D. Mean 1-year excess weight loss was 75.24%. In patients with vitamin D deficiency mean 1-year excess weight loss was 71.90 versus 76.15% in patients with optimal serum vitamin D level (p = 0.17). No significant difference was found after a 2-year follow-up. In patients presenting with vitamin D insufficiency, 1-year excess weight loss was 75.64 versus 79.34% in patients with optimal serum vitamin D level (p = 0.53). After a 2-year follow-up, there was a significant difference between patients presenting with and without vitamin D insufficiency (79.45 versus 91.71%; p = 0.01) and between patients presenting with and without hypovitaminosis D (80.50 versus 91.71%; p = 0.01). In our study, hypovitaminosis D seemed to have a negative impact on long term excess weight loss, but not on short-term outcome or postoperative complications. The role of systematic supplementation before bariatric surgery has to be explored in prospective studies.

Objective: To determine the sequential changes of blood levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in diabetics with extracapsular extraction and posterior chamber intraocular lens implantation and to study their correlation with curative effects and pos-operative complications. Methods: The serum concentrations of IL-6 and TNF-α in 39 diabetics and non-diabetics were measured by radioimmunoassay at preoperative, post-operative and on days 7, 14 and 90 postoperatively. Results: There was significant difference in the levels of the two factors between the diabetic group and non-diabetic group preoperatively (P<0.05). The serum levels of the two factors in patients with proliferative diabetic retinopathy were higher than those in non-diabetic retinopathy, and simple diabetic retinopathy post-operative (P<0.01). Post-operative complication rate was higher in patients with proliferative diabetic retinopathy than those without retinopathy and those having simple diabetic retinopathy. Conclusion: The levels of the two factors correlate with complications and curative effect of patients with proliferative diabetic retinopathy undergoing intraocular lens implantation

Weight loss improves the cardiovascular and metabolic risk associated with obesity. However, insufficient data are available about the health effects of weight gain, separate from the obesity itself. We sought to determine whether the changes in body weight before open gastric bypass surgery (OGB) would have a significant effect on the immediate perioperative hospital course. A retrospective chart review of 100 consecutive patients was performed to examine the effects of co-morbidities and body weight changes in the immediate preoperative period on the hospital length of stay and the rate of admission to the surgical intensive care unit (SICU). Of our class III obese patients undergoing OGB, 95% had ≥1 co-morbid condition and an overall SICU admission rate of 18%. Compared with the patients with no perioperative SICU admission, the patients admitted to the SICU had a greater degree of insulin resistance (homeostatic model analysis-insulin resistance 10.8 ± 1.3 versus 5.9 ± 0.5, P = .001), greater serum triglyceride levels (225 ± 47 versus 143 ± 8 mg/dL, P = .003), and had gained more weight preoperatively (.52 ± .13 versus .06 ± .06 lb/wk, P = .003). The multivariate analyses showed that preoperative weight gain was a risk factor for a longer length of stay and more SICU admissions lasting ≥3 days, as were a diagnosis of sleep apnea and an elevated serum triglyceride concentration. The results of the present retrospective study suggest that weight gain increases the risk of perioperative SICU admission associated with OGB, independent of the body mass index. Sleep apnea and elevated serum triglyceride levels were also important determinants of perioperative morbidity. In view of the increasing epidemic of obesity and the popularity of bariatric surgical procedures, we propose that additional clinical and metabolic research focusing on the understanding of the complex relationship among obesity, positive energy balance, weight gain, and perioperative

Apolipoprotein E (ApoE), which has been shown to influence serum lipid parameters, can bind to multiple types of lipids and plays an important role in the metabolism and homeostasis of lipids and lipoproteins. A previous study showed that ApoE concentration significantly affects serum lipid levels independently of ApoE polymorphism. The serum lipid levels were also closely correlated with dietary habits, and Shandong cuisine is famous for its high salt and oil contents, which widely differ among the different areas in China. Therefore, studying the effect of ApoE polymorphism on ApoE concentration and serum lipid levels in Shandong province is very important.A total of 815 subjects including 285 men and 530 women were randomly selected and studied from Jinan, Shandong province. In order to evaluate the association of ApoE polymorphism and serum level on lipid profiles, the ApoE genotypes, as well as levels of fasting serum ApoE and other lipid parameters, were detected in all subjects.The frequency of the ApoE E3 allele was highest (83.1%), while those of E2 and E4 were 9.4% and 7.5%, respectively, which are similar to those in other Asian populations. ApoE2 allele carriers showed significantly increased ApoE levels but lower levels of serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and Apolipoprotein B (ApoB).We found that ApoE level is influenced by ApoE polymorphism in a gene-dependent manner. The ApoE polymorphism showed different influences on serum lipid parameters with increasing age and body mass index (BMI) in our Shandong Han population.

Full Text Available Introduction To analyze the association between serum levels of folate and risk of biochemical recurrence after radical prostatectomy among men from the Shared Equal Access Regional Cancer Hospital (SEARCH database. Materials and Methods Retrospective analysis of 135 subjects from the SEARCH database treated between 1991-2009 with available preoperative serum folate levels. Patients' characteristics at the time of the surgery were analyzed with ranksum and linear regression. Uni- and multivariable analyses of folate levels (log-transformed and time to biochemical recurrence were performed with Cox proportional hazards. Results The median preoperative folate level was 11.6ng/mL (reference = 1.5-20.0ng/mL. Folate levels were significantly lower among African-American men than Caucasians (P = 0.003. In univariable analysis, higher folate levels were associated with more recent year of surgery (P < 0.001 and lower preoperative PSA (P = 0.003. In univariable analysis, there was a trend towards lower risk of biochemical recurrence among men with high folate levels (HR = 0.61, 95%CI = 0.37-1.03, P = 0.064. After adjustments for patients characteristics' and pre- and post-operative clinical and pathological findings, higher serum levels of folate were independently associated with lower risk for biochemical recurrence (HR = 0.42, 95%CI = 0.20-0.89, P = 0.023. Conclusion In a cohort of men undergoing radical prostatectomy at several VAs across the country, higher serum folate levels were associated with lower PSA and lower risk for biochemical failure. While the source of the folate in the serum in this study is unknown (i.e. diet vs. supplement, these findings, if confirmed, suggest a potential role of folic acid supplementation or increased consumption of folate rich foods to reduce the risk of recurrence.

Several serum tumour markers have been described for gastric cancer. Preoperative level of tumor marker helps to predict the diagnosis of gastric carcinoma. CA72-4 as a serum tumour marker for gastric cancer is evaluated, and compared its utility in this regard with that of carcinoembryonic antigen (CEA). Analysis of gastric carcinoma by serum levels of CEA and CA72-4 and their correlation with histopathology help the clinician to develop his management strategies for gastric carcinoma. A prospective observational study was carried out in the Department of Clinical Pathology, Bangabandhu Sheikh Mujib Medical University (BSMMU) in collaboration with Department of Surgery BSMMU, DMCH, Delta Hospital Limited, Dhaka, during the period of October 2010 to September 2011. Serum CA72-4 and CEA were analyzed in 71 endoscopically suspected patients for gastric carcinoma. Among them 58 cases were diagnosed as malignant gastric disease and 13 cases were nonmalignant gastric disease. Sensitivity of CA 72-4 and CEA were 48.3% and 31% respectively and specificity were 92.3% and 76.9% respectively. In poorly differentiated carcinoma, positivity for CA72-4 and CEA were 55.6% and 36.1% respectively. Because of the high positivity of CA72-4 in poorly differentiated carcinoma, CA72-4 is reliable tumour marker in advanced cases. As the sensitivity of CA72-4 was more than that of CEA in diagnosis of gastric cancer, CA72-4 can be used in conjunction with other diagnostic tests like endoscopy that would be more helpful for the patients.

Carcinoembryonic Antigen is one of most frequently checked tumor markers in cancer management. We performed statistical analysis with serum CEA data of 2626 persons who received regular health examination and were thought to be free of active disease to determine the cutoff values of serum CEA level in normal Korean adults and to study the factors influencing serum CEA levels in normal subjects. 1) The cutoff values of serum CEA in normal Korean adults in general were 9.28 ng/ml for men, 5.90 ng/ml for women. 2) Serum CEA level was influenced by age, present smoking history, sex, and abnormal findings in chest X ray. 3) Serum CEA level had no correlation with the history of amount of alcohol consumption or obesity. 4) Cutoff values of serum CEA in normal Korean adults were tabulated according to age, sex, and smoking history. Serum CEA level was influenced by age, sex, present smoking history and abnormal findings in chest X ray and cutoff values of serum CEA were tabulated according to age, sex, and smoking history.

Full Text Available Objective: To measure serum chromium level in women with gestational diabetes mellitus (GDM from Chennai, South India. Materials and Methods: Thirty women with gestational diabetes, 60 age matched controls. Inclusion criteria: Gestational age 22-28 weeks, age group 20-35 years. Exclusion Criteria: Gestational age beyond 28 weeks, malnutrition or presence of infection. Serum chromium was measured using inductive couple plasma emission spectrometer. Results: Serum chromium levels of women with GDM, 1.59+/-0.02 ng/ml (range: 0.16-4.0 ng/ml were lower than in controls (4.58+/-0.62 ng/ml; range 0.82-5.33 ng/ml (P < 0.001. However, there were no significant differences among cases and controls when subdivided by parity. Conclusions: Women with GDM from a South Indian city had lower levels of serum chromium compared to pregnant women without GDM. Studies may be done whether chromium supplementation is useful in this group of women.

A radioimmunoassay (RIA) method for erythropoietin (Epo) was developed and validated against the polycythaemic mouse assay. The correlation was good, with a r=0.94. Several other criteria of specificity were also filled by the RIA, which had a lower detection limit of 5 mU/ml. The mean serum-Epo level in 6 patients with secondary polycythaemia, 50.2 +- 26.2 mU/ml, was significantly higher than in a group of 11 normal subjects, 28.7 +- 7.2 mU/ml (P<0.0002). However, the Epo level in 31 polycythaemia vera (PV) patients, M = 21.9 +- 6.6 mU/ml, was not significantly different from normal (P = 0.006). Since previous studies with bioassay of heat-treated and concentrated plasma samples have shown a decreased serum-Epo level in PV, Epo levels were measured before and after heat treatment and concentration of samples from normals and polycythaemics. It was found that the levels of immunoreactive material increased after heat treatment and 40 times concentration in samples from normals and patients with secondary polycythaemias, but decreased in PV. We conclude that the Epo levels in serum in the low range measured by our and previous RIA:s probably are not true Epo levels but are partly due to an unspecific serum effect, that was removed by heat treatment.

Thioredoxin (Trx) is one of significant antioxidative molecules to diminish oxidative stress. Current evidence suggests that Trx is a potent antioxidant with cytoprotective functions. The aim of our study was to investigate specifically the association between serum Trx levels and acute ischemic stroke (AIS) patients. 198 AIS patients and 75 controls were enrolled to the study. Serum Trx levels were measured using an enzyme-linked immunosorbent assay (ELISA). Stroke severity was assessed with the National Institutes of Health Stroke Scale (NIHSS) score on admission. Clinical endpoint was functional outcome measured by Barthel Index (BI) 3 months after admission. Multivariate binary logistic regression analyses were performed to identify predictors. We found that serum Trx levels were significantly increased in patients as compared to controls. Serum Trx was an independent biomarker to predict ischemic stroke (OR, 1.264; 95% CI, 1.04-1.537; P = 0.019). In addition, there was a negative correlation between NIHSS score at admission and serum Trx levels in cardioembolic stroke patients (r = -0.422; P = 0.013). Furthermore, higher serum Trx levels in AIS patients were associated with favorable functional outcome. Serum Trx was an independent predictor for the functional outcome (OR, 0.862; 95% CI, 0.75-0.991; P = 0.037). Serum Trx might be as a biomarker of cardioembolic stroke severity. Increased serum Trx levels could be a useful tool to predict good prognosis in patients with AIS.

Poor nutrition status is considered a risk factor for postoperative complications in the adult population. In elderly patients, who often have a poor nutrition status, this relationship has not been substantiated. Thus, the aim of this systematic review was to assess the merit of preoperative nutrition parameters used to predict postoperative outcome in elderly patients undergoing general surgery. A systematic literature search of 10 consecutive years, 1998-2008, in PubMed, EMBASE, and Cochrane databases was performed. Search terms used were nutrition status, preoperative assessment, postoperative outcome, and surgery (hip or general), including their synonyms and MeSH terms. Limits used in the search were human studies, published in English, and age (65 years or older). Articles were screened using inclusion and exclusion criteria. All selected articles were checked on methodology and graded. Of 463 articles found, 15 were included. They showed profound heterogeneity in the parameters used for preoperative nutrition status and postoperative outcome. The only significant preoperative predictors of postoperative outcome in elderly general surgery patients were serum albumin and ≥ 10% weight loss in the previous 6 months. This systematic review revealed only 2 preoperative parameters to predict postoperative outcome in elderly general surgery patients: weight loss and serum albumin. Both are open to discussion in their use as a preoperative nutrition parameter. Nonetheless, serum albumin seems a reliable preoperative parameter to identify a patient at risk for nutrition deterioration and related complicated postoperative course.

Full Text Available Background: The etiology of multiple sclerosis (MS, a chronic demyelinative disease-is unknown. The damage of blood–brain barrier (BBB vasculature is a characteristic of MS and Homocystein (Hcy can damage BBB, then increase in total Hcy may be important in MS pathogenesis. The aim of this study was to compare the serum level of total Hcy in MS patients with control group. Methods: In a case control study, serum level of total Hcy measured in 35 MS patient and compared with 30 healthy matched controls. All patients had definitive MS according to Poser criteria, without history of myocardial infarction, stroke, neuropathy, transient ischemic attack, homocystinuria or renal failure. Results: The serum concentration of total homocystein was significantly higher in multiple sclerosis patients than healthy controls. The mean total Hcy level was 17.92± 6.9 mmol/lit in cases and 14.6±2.92 mmol/lit in controls (P=0.013. Conclusion: Serum total Homocystein may have a role in MS pathogenesis and reduction of it should be studied moreover. Key words: Multiple Sclerosis, Homocystein, Serum level

Serum hyaluronan levels are increased in dialysis patients. We evaluated several factors that influence serum hyaluronan levels in 184 patients on chronic hemodialysis (duration 2.3 +/- 2.3 [SD] years). The levels were higher than normal in the whole group and in a subgroup of 133 patients without chronic infection, liver disease, or rheumatoid arthritis (215 +/- 19 and 205 +/- 22 microg/L, respectively). There was a tendency for the levels to be higher in a subgroup of patients with hepatitis c virus (HCV) infection. There was no correlation between hyaluronan levels, alanine aminotransferase (ALT), and duration or dose of dialysis. A weak but highly significant negative correlation between serum albumin levels and serum hyaluronan and ferritin levels was seen. The data suggest that chronic inflammation may explain, at least in part, the increased hyaluronan levels found in chronic dialysis patients.

To evaluate the influence of preoperative low-level laser therapy (LLLT) on therapeutic outcomes of dogs undergoing tibial plateau levelling osteotomy (TPLO). Healthy dogs undergoing TPLO were randomly assigned to receive either a single preoperative LLLT treatment (800-900 nm dual wavelength, 6 W, 3.5 J/cm 2 , 100 cm 2 area) or a sham treatment. Lameness assessment and response to manipulation, as well as force plate analysis, were performed preoperatively, then again at 24 hours, two weeks, and eight weeks postoperatively. Radiographic signs of healing of the osteo-tomy were assessed at eight weeks postoperatively. Twenty-seven dogs (27 stifles) were included and no major complications occurred. At eight weeks postoperatively, a significant difference in peak vertical force analysis was noted between the LLLT (39.6% ± 4.7%) and sham groups (28.9% ± 2.6%), (p dogs in the LLLT group (6.6 ± 1.6 years) was greater than that for the sham group (4.5 ± 2.0, p dogs (5/8) had healed at the eight-week time point than in the sham group (3/12) despite the age difference (p = 0.11) Clinical significance: The results of this study demonstrate that improved peak vertical force could be related to the preoperative use of LLLT for dogs undergoing TPLO at eight weeks postoperatively. The use of LLLT may improve postoperative return to function following canine osteotomies and its use is recommended.

Objective: To evaluate the clinical factors associated with pathological complete response (pCR) after preoperative neoadjuvant chemoradiotherapy for rectal cancer. Methods: A retrospective analysis was performed on the clinical data of 116 patients with rectal cancer, who underwent neoadjuvant chemoradiotherapy followed by radical surgery from January 2009 to December 2012. All patients received pelvic intensity-modulated radiotherapy (50 Gy/25 fractions) with concurrent fluorouracil based chemotherapy and then underwent radical surgery 4-8 weeks later. The clinical factors associated with pCR or non-pCR were analyzed by Logistic regression. Results: Of the 116 patients, 20 (17.2%) achieved a pCR after neoadjuvant chemoradiotherapy. The univariate analysis showed that percentage of circumference of the rectal tube invaded by the tumor, preoperative serum carcinoembryonic antigen (CEA) level, T stage, N stage, distance from the anal verge, degree of tumor differentiation, and maximum tumor diameter were associated with pCR or non-pCR after neoadjuvant chemoradiotherapy for rectal cancer. The multivariate analysis revealed that percentage of circumference of the rectal tube invaded by the tumor, preoperative serum CEA level,and T stage were predictive factors for pCR or non-pCR after neoadjuvant chemoradiotherapy for rectal cancer. Conclusions: Non-circumferential tumor (percentage of circumference of the rectal tube invaded by the tumor <75 %), low CEA level, and early T stage before treatment may be associated with pCR after neoadjuvant chemoradiotherapy for rectal cancer.

We aim to assess serum sodium and potassium levels in patients with different types of cerebro-vascular accidents (CVA) in comparison to control group. A comparative cross-sectional study conducted on patients admitted to the emergency department from January to August 2012. Control group consisted of patients admitted to emergency department due to common cold, urinary tract infection, low back pain, cluster, and tension headache or migraine. Serum sodium and potassium levels were measured via standard laboratory methods. There were 77 patients in control group and 78 in CVA group. Forty nine patients from the CVA group had ischemic CVA, 11 had hemorrhagic CVA and 18 suffered a transient ischemic attack (TIA). Serum sodium level in control group was significantly lower than in patients with TIA, ischemic CVA, and hemorrhagic CVA (P < 0.001). Serum potassium level in control group was higher than patients with TIA, ischemic CVA, and hemorrhagic CVA (P < 0.001). Patients with hemorrhagic CVA showed significantly lower serum potassium level than patients with TIA and ischemic CVA (P < 0.001). Correspondingly, it was observed that serum sodium to potassium ratio was higher in patients with TIA, ischemic CVA, and hemorrhagic CVA (P < 0.001). In patients with hemorrhagic CVA serum sodium to potassium ratio was higher when compared to patients with TIA and ischemic CVA (P < 0.001). This study shows that higher serum sodium and lower serum potassium level may be associated with higher incidence of CVA. Further studies are paramount to elucidate the role of serum electrolyte levels in vascular events.

Serum cholesterol levels and dietary habits were surveyed in 27 male and 34 female Seventh-day Adventist. All subjects studied were lacto-ovo-vegetarians and a few consumed some meat products. Their serum cholesterol levels, significantly lower than those of the United States general population, showed no sex difference but increased with age and were higher in overweight males. Their levels, however, were much higher than those of true vegetarians which was most likely attributable to their consumption, even though to a limited acount, of dairy foods.

High blood pressure is very prevalent worldwide, as well as vitamin D deficiency. There are several observation data that support the concept that vitamin D is involved in the pathogenesis of hypertension. Also some clinical data demonstrate positive effect of vitamin D therapy on hypertension. We studied serum levels of vitamin D and its association with blood pressure in 30 hypertensive patients and 20 age and socioeconomic status matched healthy controls. There was no statistically significant difference in serum vitamin D levels in the group of patients compared with controls. In patients group, patients with body mass index (BMI) > 30 kg/m 2 showed statistically significant decrease in serum vitamin D levels as compared to those with BMI ≤ 30 kg/m 2 (P = 0.021). There was no significant association between serum vitamin D levels and age, systolic and diastolic blood pressure in the group of patients. A negative correlation between serum vitamin D levels and BMI was found in patients group (P = 0.045). In conclusion, no association between serum levels of vitamin D and blood pressure in hypertensive patients, but it is statistically associated with BMI. Further large scale studies are needed putting in consideration the effect of genetic factor

Adiponectin is an adipocytokine secreted from white adipose tissue. Serum level of adiponectin has been shown to be reduced in several disease states like obesity and diabetes. Hypoadiponectinemia has also been included in the list of newer risk factors for Coronary Artery Disease (CAD). In this analytical cross-sectional study serum adiponectin level was measured by Enzyme Linked Immunosorbant Assay (ELISA) in 60 cases of coronary artery disease (CAD) (both sexes, aged 40-60 yrs) and 60 healthy controls. Low levels of adiponectin were seen in CAD patients as well as controls. These levels were lower as compared to western standards. Our study conforms to the previous observation of lower serum adiponectin levels in South Asians compared to the western standards. Serum adiponectin level should be considered in the laboratory work-up of CAD patients. (author)

Objective: To explore the regulation of changes in serum leptin level in patients with diabetic retinopathy. Methods: The 120 participating subjects were of four groups: healthy controls, diabetic patients without retinopathy, patients with NPDR and patients with PDR, each group consisted of 18 males and 12 females with comparable BMI. The levels of serum leptin, IVC, insulin and blood glucose of these patients were measured and the correlation between serum leptin level and other parameters was analysed. Results: The level of serum leptin in controls, diabetic patients without retinopathy, patients with NPDR and patients with PDR were 6.91 ± 1.87 μg/L, 7,83 ±2.11 μg/L, 9.56 ± 2.43 μg/L and 11.69 ± 2.57 μg/L respectively. The patients with PDR had higher serum leptin levels than patients with NPDR (t=2.15, p < 0.05), diabetic patients without retinopathy (t = 2.71, p < 0.01), and controls (t = 3.50, p < 0.001), the patients with NPDR had higher serum leptin levels than diabetic patients without retinopathy (t = 2.23, p < 0.05) and controls (t = 2.75, p < 0.01), while the difference in serum leptin was not significant between diabetic patients without retinopathy and controls. The serum level was positively correlated to BMI (r = 0.22, p < 0.05) and FINS (r = 0.28, p < 0.01). Conclusion: Serum leptin level is elevated in patients with diabetic retinopathy and is positively correlated to the severity of the disease

Full Text Available Aim: Several epidemiological studies have shown an inverse correlation between allergy and brain cancer. The purpose of this study was to compare the serum IgE levels between patients with gliomas and nonglial tumors and their possible prognostic role. Methods: A total of 84 patients with intracranial tumors were included in this study. At clinical presentation, estimation of serum IgE levels was assessed by nephelometry. Detailed information regarding the history of allergies was collected by interview. Results: Of the 84 cases, 42 were gliomas, 23 were meningiomas, 16 were metastases and 3 were primary central nervous system lymphomas. Patients with high-grade glioma had lower IgE levels than patients with low-grade glioma. Patients with glioma and meningioma had statistical significant lower serum IgE levels than patients with metastases. Patients with glioblastoma with serum IgE levels greater than 24 U/mL had a better survival. Conclusion: Patients with glioma and meningioma had lower IgE levels than patients with metastatic lesions. A prognostic role of serum IgE levels was found in glioblastoma. Further studies in larger patient series are required in order to verify our preliminary observations.

Full Text Available Objective: To study the effect of preoperative oral S-1 combined with regional intra-arterial chemotherapy on malignant molecule expression in locally advanced unresectable gastric cancer tissue. Methods: A total of 144 patients with locally advanced gastric cancer receiving surgical resection after neoadjuvant chemotherapy in our hospital between May 2012 and August 2015 were selected and randomly divided into experimental group who received preoperative oral S-1 combined with regional intra-arterial chemotherapy and control group who received preoperative intravenous systemic chemotherapy. The levels of serum tumor markers were determined after chemotherapy, and the expression levels of tumor suppressor genes and cell cycle-related molecules in tumor tissue were determined after surgical resection. Results: After neoadjuvant chemotherapy, the serum G-17, TK-1, CEA, CA19-9, CA12-5, CA72-4 and CK, CK-MB, ALT, AST levels of experimental group were significantly lower than those of control group; after surgical resection, the p16, p27, PTEN and TXNIP mRNA levels in tumor tissue of experimental group were significantly higher than those of control group while CyclinB2, CyclinD1, CyclinE, CDK1 and CDK2 mRNA levels were significantly lower than those of control group. Conclusions: Preoperative oral S-1 combined with regional intra-arterial chemotherapy can more effectively kill gastric cancer cells, reduce tumor load, inhibit cell cycle and promote cell apoptosis.

This study was designed to assess the efficiency of the serum thyrotropin to thyroglobulin ratio for thyroid nodule evaluation in euthyroid patients. Cross-sectional study. Sun Yat-sen University Cancer Center, State Key Laboratory of Oncology in South China. Retrospective analysis was performed for 400 previously untreated cases presenting with thyroid nodules. Thyroid function was tested with commercially available radioimmunoassays. The receiver operating characteristic curves were constructed to determine cutoff values. The efficacy of the thyrotropin:thyroglobulin ratio and thyroid-stimulating hormone for thyroid nodule evaluation was evaluated in terms of sensitivity, specificity, positive predictive value, positive likelihood ratio, negative likelihood ratio, and odds ratio. In receiver operating characteristic curve analysis, the area under the curve was 0.746 for the thyrotropin:thyroglobulin ratio and 0.659 for thyroid-stimulating hormone. With a cutoff point value of 24.97 IU/g for the thyrotropin:thyroglobulin ratio, the sensitivity, specificity, positive predictive value, positive likelihood ratio, and negative likelihood ratio were 78.9%, 60.8%, 75.5%, 2.01, and 0.35, respectively. The odds ratio for the thyrotropin:thyroglobulin ratio indicating malignancy was 5.80. With a cutoff point value of 1.525 µIU/mL for thyroid-stimulating hormone, the sensitivity, specificity, positive predictive value, positive likelihood ratio, and negative likelihood ratio were 74.0%, 53.2%, 70.8%, 1.58, and 0.49, respectively. The odds ratio indicating malignancy for thyroid-stimulating hormone was 3.23. Increasing preoperative serum thyrotropin:thyroglobulin ratio is a risk factor for thyroid carcinoma, and the correlation of the thyrotropin:thyroglobulin ratio to malignancy is higher than that for serum thyroid-stimulating hormone. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

To evaluate the impact of preoperative biliary drainage on surgical morbidity in hilar cholangiocarcinoma patients underwent surgery. One hundred and eleven consecutive patients with hilar cholangiocarcinoma whose serum total bilirubin (TBIL) level > 85 micromol/L and underwent surgery in the period from June 1998 to August 2007 were enrolled. There were 67 male and 44 female patients, aged from 26 to 82 years old with a mean of 56 years old. Fifty-five patients underwent preoperative biliary drainage with a mean of 11.4 d of drainage period (drainage group), the other (n = 56) were the non-drainage group. The preoperative TBIL level of drainage group was (154 +/- 69) micromol/L, which was significantly lower than the value of pre-drainage (256 +/- 136) micromol/L (P = 0.000) and the value of non-drainage group (268 +/- 174) micromol/L (P = 0.005). ALT and GGT levels could be lowered by preoperative biliary drainage. The postoperative complications of these two groups were comparable (36.3% vs. 28.6%, P = 0.381). Four patients in drainage group and 5 patients in non-drainage group died of liver failure. Multivariate logistic regression indicated that hepatectomy (OR = 0.284, P = 0.003) was the independent risk factor associated with postoperative morbidity. Bismuth-Corlette classification (OR = 0.211, P = 0.028) was the independent risk factor linked to postoperative mortality. Preoperative biliary drainage could alleviate liver injury due to hyperbilirubin, but it could not decrease the surgical morbidity and postoperative mortality. Concomitant hepatectomy and Bismuth-Corlette classification were independent risk factors linked to surgical risks.

Full Text Available Introduction : Vitiligo is an acquired, idiopathic disorder characterized by circumscribed depigmented macules and patches, which affects approximately 0.1–2% of the general population worldwide. Zinc is an essential trace element that is necessary for growth and development at all stages of life. Some studies have reported an association between serum zinc levels and vitiligo. Aim : To measure the serum zinc level in patients with vitiligo compared to healthy subjects. Material and methods : One hundred patients with vitiligo and 100 healthy controls were referred to our clinic. The two groups were matched for age and sex. Atomic absorption spectrophotometry was used to measure serum zinc levels. The statistical analysis was performed using SPSS software. Results : The mean serum level of zinc in vitiligo patients and controls was 80.11 ±17.10 µg/dl and 96.10 ±16.16 µg/dl, respectively. The serum zinc level in patients with vitiligo was significantly lower than in healthy controls (p = 0.0001. Conclusions : The results of our study revealed a significant association between vitiligo and serum zinc levels. A relative decrease in the serum zinc level in vitiligo patients can highlight the role of zinc in the pathogenesis of vitiligo, and large-scale studies need to be conducted to confirm these findings and assess the effect of oral zinc supplements in patients with low zinc levels.

Full Text Available Context: Extensive bleeding associated with liver transplantation is a major challenge faced by transplant surgeons, worldwide. Aims: To evaluate the blood component consumption and determine preoperative factors that predict the same in living donor liver transplantation (LDLT. Settings and Design: This prospective study was performed for a 1 year period, from March 2010 to February 2011. Materials and Methods: Intra- and postoperative utilization of blood components in 152 patients undergoing LDLT was evaluated and preoperative patient parameters like age, gender, height, weight, disease etiology, hemoglobin (Hb, hematocrit (Hct, platelet count (Plt, total leukocyte count (TLC, activated partial thromboplastin time (aPTT, international normalized ratio (INR, serum bilirubin (T. bilirubin, total proteins (T. proteins, albumin to globulin ratio (A/G ratio, serum creatinine (S. creatinine, blood urea (B. urea, and serum electrolytes were assessed to determine their predictive values. Univariate and stepwise discriminant analysis identified those factors, which could predict the consumption of each blood component. Results: The average utilization of packed red cells (PRCs, cryoprecipitates (cryo, apheresis platelets, and fresh frozen plasma was 8.48 units, 2.19 units, 0.93 units, and 2,025 ml, respectively. Disease etiology and blood component consumption were significantly correlated. Separate prediction models which could predict consumption of each blood component in intra and postoperative phase of LDLT were derived from among the preoperative Hb, Hct, model for end-stage liver disease (MELD score, body surface area (BSA, Plt, T. proteins, S. creatinine, B. urea, INR, and serum sodium and chloride. Conclusions: Preoperative variables can effectively predict the blood component requirements during liver transplantation, thereby allowing blood transfusion services in being better prepared for surgical procedure.

Full Text Available Hypoalbuminemia may cause interstitial edema and hemodilution, which we hypothesized may influence serum sodium levels. Our purpose was to compare serum sodium levels of hospitalized adults with or without hypoalbuminemia. All sodium and albumin serum levels of 142 adults hospitalized at general medical wards over a six-month period were searched at a University Hospital mainframe computer. Relevant laboratory data and clinical details were also registered. Hypoalbuminemia was defined by serum albumin concentration < 3.3 g/dl Fisher, Mann-Whitney, and Student's t tests were applied to compare groups with or without hypoalbuminemia. Ninety-nine patients, classified as hypoalbuminemic, had lower blood hemoglobin (10.68 ± 2.62 vs. 13.54 ± 2.41, and sodium (135.1 ± 6.44 vs. 139.9 ± 4.76mEq/l and albumin (2.74 ± 0.35 vs. 3.58 ± 0.28g/dl serum levels than non-hypoalbuminemic (n=43. Pearson's coefficient showed a significant direct correlation between albumin and sodium serum levels (r=0.40 and between serum albumin and blood hemoglobin concentration (r=0.46. Our results suggest that hypoalbuminemic adults have lower serum sodium levels than those without hypoalbuminemia, a phenomenon that may be at least partially attributed to body water retention associated with acute phase response syndrome.

Full Text Available Introduction : Systemic sclerosis (SSc is achronic connective tissue disease characterized by microangiopathy with inadequate angiogenesis. Angiostatin (AS is a potent antiangiogenic factor specifically inhibiting proliferation and inducing apoptosis of vascular endothelial cells. Aim : To evaluate the level of angiostatin in the serum of patients with SSc. Material and methods : Serum levels of AS were measured in 20 SSc patients and 12 healthy controls. Results : A statistically significant difference in the serum levels of AS in SSc patients was observed compared to the control group (636.51 vs. 869.20 ng/ml; p = 0.012. Significant correlations between limited and disseminated SSc (lSSc/dSSc were not found, however, a difference between lSSc and the control group was demonstrated (620.00 vs. 869.20 ng/ml; p = 0.011. The serum level of AS was not associated positively with organ changes caused by SSc. However, a statistically significant lower serum level of AS was observed in patients with SSc and no esophageal (p = 0.008 or pulmonary changes (p = 0.007 compared to the control group. Conclusions : Our results reveal significant differences in AS level in SSc patients compared to the healthy controls, and suggest that a low level of AS may occur as a result of impaired angiogenesis.

Objective: To investigate the effect of different status of thyroid function (hypothyroidism and hyperthyroidism as well as euthyroid status) on serum ghrelin and leptin levels. Methods: The levels of serum ghrelin and leptin were determined by radio immunoassay in 46 untreated subjects with hyperthyroidism, 15 hyperthyroid patients achieved a euthyroid status after radioiodine 131 I therapy, 21 cases of hypothyroidism and 18 cases of normal controls, respectively. Meanwhile, the serum levels of free triiodothyronine (FT 3 ), free thyroxine (FT 4 ) and thyroid-stimulating hormone (TSH) were measured by chemiluminescence immune assay. Results: (1) The levels of serum ghrelin in untreated hyperthyroidism were significantly lower than those in hyperthyroid patients achieved a euthyroid status (t=3.21, P 3 (r=-0.29, P 4 (r=-0.26, P< 0.05), positively correlated with serum TSH (r=0.36, P<0.05); serum leptin levels did not correlate with thyroid hormone. Conclusion: The levels of serum ghrelin were differently under different thyroid functional status and correlated with thyroid hormone, while serum leptin were not. (authors)

Objective: To investigate the levels of serum leptin in patients with graves' disease. Methods: Serum leptin levels were measured with IRMA in 51 patients with hyperthyroidism as well as 46 hypothyroid and 50 euthyroid subjects as controls. Serum TSH, free T 3 and free T 4 (FT 3 and FT 4 ) were also measured. Body fat percentage (% Fat) and body mass index (BMI) were calculated. Results: Serum leptin levels were significantly lower in patients with graves' disease (male 2.05 ± 1.54μg/L, female 7.47±5. 08 μg/L), than those in hypothyroid and euthyroid subjects. Levels in hypothyroid patients were significantly higher than those in controls, however, excluding the body fat factor, there were no obvious difference. Serum leptin levels in all the 3 groups were significantly positively correlated with BMI. The levels were negatively correlated with FT 3 , FT 4 levels and positively correlated with TSH levels but both were not significant. Serum leptin levels were 2-3 times higher in women than in men among all 3 groups. Conclusion: Thyroid functional status affected serum leptin levels indirectly through the amount of body fat.

Objective: To study the clinical meanings of changes of serum C-peptide levels and insulin/C-peptide ratio. Methods: Serum insulin and C-peptide levels were determined with RIA in 171 patients with DM-2 of all ages (31-50, n= 50, 51-60, n=60, over 60, n=61) and 50 patients with renal insufficiency. The insulin/C-peptide ratio were calculated. Results: The serum C-peptide and insulin levels in patients with renal insufficiency were significantly higher than those in diabetics of all age groups and the insulin/C-peptide ratio were significantly lower than those in diabetics (P 0.05), but the serum C-peptide levels increased as the age of patients increased with decrease of insulin/C-peptide ratio (P<0.01). Conclusion: Abnormal changes of C-peptide levels and insulin/C-peptide ratio in diabetics (the age-factor corrected) might reflect renal dysfunction. (authors)

Full Text Available Abstract Background Synuclein gamma (SNCG, initially identified as a breast cancer specific gene, is aberrantly expressed in many different malignant tumors but rarely expressed in matched nonneoplastic adjacent tissues. In this study, we investigated the prognostic potential of SNCG in colon cancer particularly in the patients with normal carcinoembryonic antigen (CEA levels. Methods SNCG levels were assessed immunohistochemically in cancer tissues from 229 colon adenocarcinoma patients with a mean follow-up of 44 months. Correlations between SNCG levels and clinicopathologic features, preoperative serum CEA level, and clinical outcome were analyzed statistically using SPSS. Results SNCG levels in colon adenocarcinoma were closely associated with intravascular embolus and tumor recurrence but independent of preoperative serum CEA levels. SNCG expression was an independent prognostic factor of a shorter disease-free survival (DFS and overall survival (OS (P P = 0.001, P = 0.001, 0.002 for 97 patients with normal preoperative serum CEA level. Conclusions Our results suggest for the first time that SNCG is a new independent predicator for poor prognosis in patients with colon adenocarcinoma, including those with normal CEA levels. Combination of CEA with SNCG improves prognostic evaluation for patients with colon adenocarcinoma.

To study the changes in concentrations of serum hyaluronic acid in uncomplicated human pregnancies. We determined the concentrations of serum hyaluronic acid, using a specific enzyme-linked immunosorbent assay, in 70 nonpregnant women, 250 women during their pregnancies, and 68 women at the time of parturition. Results were analyzed for statistical significance with Scheffé test for multiple comparisons. During pregnancy, mean (+/- standard deviation) serum hyaluronic acid levels were 11.4 +/- 4.5, 13.6 +/- 2.8, 20.6 +/- 1.5, and 46.9 +/- 7.9 ng/mL at 5-14 (n = 47), 15-26 (n = 46), 27-37 (n = 58), and 38-40 (n = 99) weeks' gestation, respectively. Pregnant women in labor (n = 68) had significantly higher levels (100.4 +/- 11.3 ng/mL) than did women at term but not in labor (P hyaluronic acid concentrations increase as pregnancy progresses and serum levels increase significantly at term. Hyaluronic acid may be associated with cervical ripening during parturition.

This work undertakes, in a second part, the clinical exploration of 947 serum digoxin levels of 281 hospitalized patients on a cardiology ward. Our results, which coincide with those of other researchers, have led us to draw certain practical conclusions: the posology is determined first of all according to kidney function, weight and age of the patient. When the treatment is insufficient or, on the other hand, poorly tolerated, a serum digoxin level is performed permitting thus: in the case of ineffective treatment: to be sure of the patient's cooperation, to increase the posology if the serum digoxin level is not in the toxic zone, to discover an eventual pharmacokinetic problem; to establish the responsability of digitalis (when there are signs of intolerance or of intoxication), in case of arrhythmia, in patients with pacemakers, when associated drugs are capable of causing similar adverse effects; to better manage a digitalis treatment in a high risk patient (unstable renal function, advanced myocardial disease, chronic obstructive disease) [fr

Interleukin 33 (IL-33) is a cytokine involved in fibrotic disorders. We have analyzed IL-33 levels in the sera and peritoneal fluids of women with various forms of endometriosis and investigated the correlation with disease activity. We conducted a prospective laboratory study in a tertiary-care university hospital between January 2005 and December 2010. Five hundred and ten women with histologically proven endometriosis and 132 endometriosis-free controls were enrolled in this study. Complete surgical exploration of the abdominopelvic cavity was performed in each patient. Blood samples and peritoneal fluids were obtained before and during surgical procedures, respectively. IL-33 was measured by an enzyme-linked immunosorbent assay in sera and peritoneal fluids, and the concentrations correlated with the extent and the severity of endometriotic lesions. IL-33 was detectable in 23.1% of serum samples from all 642 women studied and 75.0% of peritoneal fluid samples studied (44 women with endometriosis and 36 controls). Serum IL-33 was higher in deeply infiltrating endometriosis (DIE) (median, 104.9 pg/ml; range, 8.0-104.9) than in endometriosis-free women (median, 61.3 pg/ml; range, 7.5-526.0; P = 0.022) or in women affected by superficial endometriosis (median, 36.8 pg/ml; range, 7.5-179.0; P Peritoneal IL-33 was higher in DIE than in endometriosis-free women (median, 642.0 pg/ml; range, 25.9-3350.6 versus median, 194.2 pg/ml; range, 12.7-1818.2, respectively; P = 0.003). We found positive correlations between serum IL-33 concentration and intensity of dysmenorrhea (r = 0.174; P = 0.028) and gastrointestinal symptoms (r = 0.199; P = 0.027), total number of DIE lesions (r = 0.224; P = 0.016) and the worst DIE lesion (r = 0.299; P endometriosis and principally in DIE. Elevated serum IL-33 is correlated with the intensity of preoperative painful symptoms, and with the extent and severity of the DIE. IL-33 may be considered as a novel cytokine involved in the

The elucidation of the changes of fetuin-A in the context of bariatric surgery. Twenty obese patients (8 males, 12 females; body mass index = 42.5±3.4 kg/m2) were studied at baseline and 6 months after bariatric surgery. Serum fetuin-A levels did not differ with regard to the presence of each individual component of the Metabolic Syndrome (MetS) at baseline, except for hypertriglyceridaemia [increased serum fetuin-A levels (p=0.011)]. Circulating fetuin-A was positively correlated with serum triglycerides (TG) (r=0.461, p=0.047) and negatively correlated with serum globulins (r=-0.477, p=0.033) and C-reactive protein (CRP) (r=-0.604, p=0.010), while it independently predicted TG at baseline. Circulating fetuin-A did not change during the 6 months either in the whole population or in the subgroups of patients who were positive for each individual component of MetS at baseline and negative for this component at 6 months of follow-up, except for hypertriglyceridaemia [reduction of serum fetuin-A levels (p=0.046)]. The subgroup of patients with a decrease in circulating fetuin-A during the 6 months was characterized by a smaller reduction of serum globulins (p=0.003) and CRP (p=0.049). The change in serum fetuin-A levels over the 6 months was positively correlated with the change in TG (r=0.592, p=0.006) and negatively correlated with the change in serum globulins (r=-0.523, p=0.018) and CRP (r=-.494, p=0.037). Circulating fetuin-A predicted serum triglycerides before as well as 6 months after bariatric surgery.

Full Text Available Background. Few studies have shown that self-reported secondhand smoke exposure in never smokers is associated with high blood pressure. However, there are no studies investigating the relationship between secondhand smoke exposure, measured objectively by serum cotinine levels, and high blood pressure in never smokers. Methods. We examined never smokers (n=2027 from the National Health and Nutrition Examination Survey 2005–2008. Our exposure of interest was the secondhand smoke exposure estimated by serum cotinine level and our outcome was prehypertension (n=734, defined as a systolic blood pressure of 120–139 mmHg or diastolic blood pressure of 80–89 mmHg. Results. We found that, in never smokers, serum cotinine levels were positively associated with prehypertension. Compared to those with cotinine levels in the lowest quartile (≤0.024 ng/mL, the multivariable odds ratio (95% confidence interval of prehypertension among those with cotinine levels in the highest quartile (≥0.224 ng/mL was 1.45(1.00, 2.11; P trend =0.0451. In subsequent subgroup analyses, the positive association was found to be stronger among men, non-Whites, and non-obese subjects. Conclusion. Higher secondhand smoke exposure measured objectively by serum cotinine levels was found to be associated with prehypertension in certain subgroups of a representative sample of the US population.

Endothelial dysfunction has been described as the final common pathophysiological pathway in the development of preeclampsia. Since it has been suggested that homocyst(e)ine damages endothelial cells, we measured serum homocyst(e)ine levels in women with preeclampsia and in healthy pregnant women in order to find a new prognostic parameter for women with preeclampsia. Forty-five women with preeclampsia and 45 healthy women with uncomplicated pregnancies, matched for age and parity, were entered into the study. Serum homocyst(e)ine levels were measured by gas chromatography-mass spectrometry analysis and correlated to clinical data. Logistic regression models were used to analyse the influence of serum homocyst(e)ine levels on the presence of preeclampsia versus healthy pregnant women and on the risk of premature termination of pregnancy due to preeclampsia. Median serum homocyst(e)ine levels in women with preeclampsia and healthy pregnant women were 14.2 (range 5.7-38.1) mumol/L and 15.1 (range 5.2-23.1) mumol/L, respectively (Mann-Whitney U-test, p = 0.8). In univariate logistic regression models, serum homocyst(e)ine levels had no significant influence on the odds of presenting with preeclampsia versus healthy pregnant women (univariate logistic regression model, p = 0.8) and on the odds of premature termination of pregnancy due to preeclampsia (univariate logistic regression model, p = 0.3). Serum homocyst(e)ine levels are not elevated in women with preeclampsia and are not associated with clinical outcome in women with preeclampsia.

Objective: To investigate the relationship between the serum level of endostatin and the clinical pathophysiological characteristics in patients with primary lung cancer. Methods: The serum levels of endostatin were detected in 48 patients with primary lung cancer and 50 patients with benign pulmonary diseases by enzyme-linked immunosorbent assay (ELISA) method. Results: Serum endostatin level in patients with primary lung cancer was significantly higher than it in patients with benign pulmonary diseases (P<0.01). It was higher in adenocarcinoma group than that in squamous cell carcinoma and small cell carcinoma group (P<0.05). The level of serum endostatin in lung cancer with TNM stage III + IV was higher than that in patients in stage I + II (P<0.01). And it was also higher in patients suffering from lung cancer with metastasis than that in patients with no metastasis (P<0.05). However, there was not a significant relation between serum endostatin level the location of the tumor and lymph node metastasis. Conclusion: Serum endostatin level in expressed higher in patients with primary lung cancer. There is significant relationship between serum endostatin level, histological classification, TNM stage and metastasis of lung cancer. (authors)

Diganta Das

2015-01-01

Full Text Available Introduction: Olanzapine is a commonly used antipsychotic. Prolactin elevation is a common adverse effect of anstipsychotics, and serum prolactin elevation is seen in about 30% patients treated with olanzapine. There are confounding results about dose dependency of olanzapine and prolactin elevation, and also the duration of treatment. Method: Fifty six patients, 36 male and 20 female, who were taking olanzapine for any condition for more than a month at a constant dose were enrolled in the study. Patients’ age, weight, body mass index (BMI, serum prolactin levels, and some biochemical values were recorded. Patients were taken from the review outpatient department (OPD after due consent. Results: Five each in male and female groups showed elevation of serum prolactin (estimated to be high if >20 ng/dl for males, and >25 ng/dl for females. In females, the elevation was found at lesser dose of olanzapine (13 mg/day, in males 18 mg/day and early in the treatment (2.4 months vs. 9.7 months in males. Males tended to show raised prolactin with higher doses of olanzapine (mean 18 mg/day. Females (26.31% also showed higher prevalence of prolactin elevation compared to males (13.51%. No other parameter was found to modify the prolactin levels. Conclusion: Olanzapine causes elevation of serum prolactin, though lesser degree than some other antipsychotics. Females are more prone to have raised serum prolactin with olanzapine compared to males. However, the elevation seems to be transient. Higher doses of olanzapine tend to cause elevation of serum prolactin. Serum prolactin estimation in patients taking olanzapine may be undertaken to maintain quality life, particularly in females.

Recent evidence from animal studies indicates that fibroblast growth factor 21 (FGF21), an endocrine hormone that regulates glucose, lipid metabolism, and energy homeostasis, is regulated by T3. However, the role of FGF21 in hyperthyroid patients is unknown. The objective was to study serum FGF21 levels in hyperthyroid patients and the association of serum FGF21 levels with hyperthyroidism. This was a case-control study. A total of 119 hyperthyroid patients and 108 healthy subjects were recruited. Of them, 41 hyperthyroid patients received thionamide treatment for 3 months until euthyroidism was obtained. Serum FGF21 levels were determined using the ELISA method. Serum FGF21 levels were significantly elevated in hyperthyroid patients as compared with normal subjects [median 290.67 (interquartile range, 156.60-502.33) vs 228.10 (169.85.25-320.10) pg/mL; P treatment, serum FGF21 levels in hyperthyroid patients declined markedly from 249.10 (139.10-444.00) to 106.90 (38.70-196.15) pg/mL (P hyperthyroidism. With adjustment for potential confounders, serum FGF21 remained independently associated with hyperthyroidism, with an adjusted odds ratio of 3.123 (95% confidence interval, 1.306-7.468) (P = .010). Serum FGF21 levels were elevated in patients with hyperthyroidism and declined after thionamide treatment. And serum FGF21 level was independently associated with hyperthyroidism.

Hyperhomocysteinemia has been considered an independent risk factor in the development of stroke. The present study was undertaken to evaluate serum homocysteine levels in patients with cerebrovascular accidents among the Manipuri population and to compare with the normal cases. Ninety-three cerebrovascular accident cases admitted in the hospital were enrolled for the study and twenty-seven age and sex matched individuals free from cerebrovascular diseases were taken as control group. Serum homocysteine levels were estimated by ELISA method using Axis homocysteine EIA kit manufactured by Ranbaxy Diagnostic Ltd. India. The finding suggests that hyperhomocysteinemia is associated with cerebrovascular accident with male preponderance, which increases with advancing age. However, whether hyperhomocysteinemia is the cause or the result of cerebrovascular accidents needs further investigations.

This study was to investigate the correlation between ovarian chocolate cysts and serum carbohydrate antigen (CA)-125 levels and to demonstrate the effect of ultrasound-guided interventional sclerotherapy (UGIS) on serum CA-125 levels. Based on the serum CA-125 level, as determined by chemiluminescence detection prior to UGIS, 105 patients with ovarian chocolate cysts were divided into the normal group (CA-125 ≤ 35 U/mL, 45 patients) and the abnormal group (35 U/mL history, child-bearing history, abortion history and surgical history. The ultrasonography characteristics were cyst diameter, cyst wall thickness and the side on which the cyst occurred. The correlations between serum CA-125 levels pretreatment and the clinical indicators and ultrasonography characteristics was analyzed. The serum CA-125 levels pretreatment, 3 months post-treatment and 6 months post-treatment were compared. The pretreatment serum CA-125 levels of the 105 patients positively correlated with disease duration (r = 0.3932, P = 0.0040), dysmenorrhea history (r = 0.2351, P = 0.0111), cyst diameter (r = 0.3415, P chocolate cysts. © 2014 The Authors.

Irisin has been proposed to regulate metabolic diseases such as obesity, diabetes or metabolic syndrome which are common comorbidities in psoriasis. The aim of this study was to evaluate the serum irisin level in psoriasis and elucidate possible associations with disease activity, inflammatory or metabolic parameters and topical treatment. Thirty-seven individuals with active plaque-type psoriasis and 15 healthy controls were enrolled. Blood samples were collected before and after two weeks of therapy. Serum irisin concentrations were examined by enzyme-linked immunosorbent assay (ELISA). The results were correlated with psoriasis area and severity index (PASI), body mass index (BMI), inflammatory and biochemical markers, lipid profile and effectiveness of topical treatment. Irisin serum levels were insignificantly increased in psoriatic patients in comparison to the controls (p = 0.38). No significant correlations between investigated adipokine and several indicators of metabolic disorders, nor BMI (p = 0.37) or PASI (p = 0.5) were found. Significant positive correlations with C-reactive protein (CRP) (0.009), lipocalin-2 (p = 0.02), age (p = 0.02) and disease duration (p = 0.008) were noted. After topical treatment, serum irisin level did not significantly change (p = 0.31), despite clinical improvement. Irisin might be a marker of inflammation in psoriatic patients, but may not be a reliable indicator of metabolic conditions, severity of psoriasis nor efficacy of antipsoriatic treatment.

Full Text Available Objective: To study the effect of preoperative S-1 combined with regional transcatheter arterial chemoembolization on malignant degree of locally advanced gastric cancer. Methods: A total of 134 patients who were diagnosed with advanced gastric cancer in our hospital from May 2012 to December 2014 were selected for study, received surgical resection after chemotherapy, and were divided into intravenous chemotherapy group and combined treatment group according to different chemotherapy regimens. After chemotherapy and before operation, serum tumor marker levels were detected; after operation, recurrence and metastasis-related molecule levels in tumor tissue were detected. Results: After chemotherapy and before operation, serum CEA, CA199, CA72-4, TSGF, ESM-1 and DKK-1 levels of combined treatment group were significantly lower than those of intravenous chemotherapy group; TET1, TET2, LATS1 and RUNX3 levels in tumor tissue of combined treatment group were higher than those of intravenous chemotherapy group while Sipa1, GOLPH3, AEP, MT2- MMP, OPN, Galectin-1, Galectin-3 and Galectin-9 levels were lower than those of intravenous chemotherapy group. Conclusions: Compared with systemic intravenous chemotherapy, preoperative S-1 combined with regional transcatheter arterial chemoembolization can more effectively kill gastric cancer cells and prevent tumor recurrence and metastasis at molecular level.

Patient with arterial hypertension and no definable cause are said to have essential, primary or idiopathic hypertension. A total of 100 patients suffering from essential hypertension and 100 control subjects with almost same mean age and sex distribution were enrolled in this study. Levels of serum uric acid, total cholesterol, TG, and HDL-c were determined by enzymatic colorimetric method. Serum LDL-c and VLDL-c was calculated by using Friedewald and Wilson's formulae. The study was aimed to find out the levels of serum uric acid and lipid profile in patients with essential hypertension and to compare them with levels of normal healthy individuals. Results show increased level of serum uric acid and lipid parameters except for HDL-c, which was significantly, decreased in patients with essential hypertension as compared to the control subjects. Variations in aforementioned parameters were also observed on comparing the obese and the non-obese patients. It can be concluded from the present study that the essential hypertension is associated with abnormalities in the levels of serum uric acid and lipid profile. (author)

The aim of this clinical study was to determine whether there is a relationship between total serum testosterone, free testosterone, FSH (Follicle-Stimulating Hormone), LH (Luteinizing Hormone) and serum prostate specific antigen (PSA) levels. We postulated that such a correlation existed then the use of hormone specific reference ranges might enhance the usefullness of PSA concentrations 40 years of age visiting our urology outpatient clinics. PSA was correlated to age (r = 0.23, p = 0.019), but there none between serum testosterone and age. No significant correlation was noted between testosterone or free testosterone and serum PSA levels, and none between serum FSH or LH and PSA. In age specific reference groups (41-49; 50-59; 60-69 years), we found no significant correlation between PSA and hormone concentrations. In this population of eugonadal men with serum PSA values less than 2.5 ng/ml, serum androgens and pituitary hormones do not appear to correlate with serum PSA.

Because there is no absolute indicator of the nutritional status and prognosis in patients with severe aspiration problems, it is quite difficult to arrive at a true long-time prognosis. By performing surgery for intractable aspiration on such patients, both the prognosis and QOL of the patients could be expected to improve. In our department, we have experienced patients dying within 6 months after surgery. In these cases, the patient's preoperative nutritional status was not good. Therefore, we consider that, when we adopt this procedure, there should be some indicators we should use which could have an effect on the prognosis of such nutritionally-challenged patients. In patients who underwent surgery for intractable aspiration; we examined the relationship between their survival and the prognostic nutritional index (PNI) which is an indicator of the risk of complications such as post-operative events in the surgical field. We investigated the relationship between the prognosis and the postoperative indicators of each of the following: WBC, CRP, serum albumin level, and PNI. Out of a total of 31 cases, the average O-PNI of eight cases in which death occurred was 29.45, and the average of six cases in which death occurred within 6 months after surgery was 28.26. The average O-PNI of the survivors was 36.01. A significant association was noted between the early postoperative deaths and some of the four indicators namely that serum albumin level and O-PNI. Based on the ROC curve, the O-PNI offered higher precision than the albumin level. The cut-off value of the O-PNI value for early postoperative mortality rate was 32. The early postoperative mortality rate was 44.4% in patients with less than 32 O-PNI in the preoperative examination, but if it were O-PNI 32 or more, the early postoperative mortality rate was 9.1%, significantly lower. Therefore, O-PNI could be useful as one of the prognostic evaluation factors in the case of preoperative surgery for intractable

Full Text Available Background Occupational exposure to excessive noise is one of the biggest work-related challenges in the world. This phenomenon causes the release of stress-related hormones, which in turn, negatively affects cardiovascular risk factors. Objectives The current study study aimed to determine the level of workers’ serum aldosterone in light of the combined effect of sound pressure level, exposure time and serum potassium level. Methods This cross-sectional, descriptive, analytical study was conducted on 45 workers of Gol-Gohar Mining and Industrial Company in the fall of 2014. The subjects were divided into three groups (one control and two case groups, each including 15 workers. Participants in the control group were selected from workers with administrative jobs (exposure to the background noise. On the other hand, participants in the case groups were selected from the concentrator and pelletizing factories exposed to excessive noise. Serum aldosterone and potassium levels of participants were assessed at three different time intervals: at the beginning of the shift and before exposure to noise (7:30 - 8:00 AM, during exposure to noise (10:00 - 10:30 AM, and during continuous exposure (1:30 - 2:00 PM. The obtained data were transferred into SPSS ver. 18. Repeated measures analysis of variance (ANOVA was used to develop the statistical model of workers’ aldosterone level in light of the combined effect of sound pressure level, exposure time, and serum potassium level. Results The results of the final statistical model to determine the level of serum aldosterone based on the combined effect of sound pressure level, exposure time and serum potassium level indicated that the sound pressure level had a significant influence on the human’s serum aldosterone level (P = 0.04. In addition, the effects of exposure time and serum potassium on aldosterone level were statistically significant with P-values of 0.008 and 0.001, respectively. Conclusions

To measure serum leptin levels and compare them in lean and obese subjects and to identify correlation between serum leptin levels, heart rate and hypertension in lean and obese subjects among adult females. Seventy female subjects with different body mass indices were selected from OPD of Jinnah Medical and Dental College Hospital (OPD), Karachi. Heart rate was counted manually; blood pressure was measured by mercury sphygmomanometer while serum leptin was measured using enzyme-linked immunoassay. The outcomes hypertension and heart rate were correlated to risk factor leptin. Mean heart rate, systolic and diastolic blood pressure and serum leptin levels of obese people were 90+-1, 142+-2, 89+-1 and 24.13+-1.7 respectively, which were significantly higher as compared to lean subjects (p<0.05). All the parameters correlated positively and significantly with increasing BMI. There was a relationship of tachycardia and hypertension with high serum leptin levels in obesity. Serum leptin levels increase with the level of obesity. Hyper-leptinemia is associated with tachycardia and increases in both systolic and diastolic blood pressure in obesity via complex mechanisms.

To evaluate the significance of assay of serum thyroglobulin(Tg) in monitoring the course of the thyroid cancer or its response to treatment, serum thyroglobulin levels were measured in 41 patients with thyroid cancer who visited Seoul National University Hospital from August, 1981 to August, 1982. The results were as follows: 1) Serum Tg levels 1-3 months after thyroidectomy was 31±23 ng/ml(mean±S.D.) in 14 patients without metastasis, 66±41 ng/ml in 21 patients with regional metastasis and 176±59 ng/ml in 6 patients with distant metastasis and there were significant differences among three groups(p 131 I treatment were 134±62 ng/ml and 67±52 ng/ml respectively. 3) In the follow-up measurement of serum Tg levels every 3 months for about 1 year, almost all serum Tg levels were below 60 ng/ml in 12 patients without distant metastasis and serum Tg levels were elevated above 60 ng/ml in 5 of 6 patients with distant metastasis. 4) In 6 patients with distant metastasis, serum Tg levels were elevated in 5 patients and 131 I Whole body scan showed definite metastatic evidence in 3 patients and suspicious evidence in 1 patient. From above results, we concluded that serum Tg level is very useful as an indicator of recurrence or metastasis in patients with thyroid cancer after operation.

Full Text Available Chronic inflammation associated with inflammatory bowel disease (IBD results in increased oxidative stress that damages the colonic microenvironment. Low levels of serum bilirubin, an endogenous antioxidant, have been associated with increased risk for Crohn's disease (CD. Therefore, the aim of this study was to examine whether total serum bilirubin levels are associated with ulcerative colitis (UC. We identified a retrospective case-control population (n = 6,649 from a single tertiary care center, Penn State Hershey Medical Center (PSU and a validation cohort (n = 1,996 from Virginia Commonwealth University Medical Center (VCU. Cases were age- and sex-matched to controls (PSU: CD n = 254, UC n = 187; VCU: CD n = 233, UC n = 124. Total serum bilirubin levels were obtained from de-identified medical records and segregated into quartiles. Logistic regression analysis was performed on each quartile of total serum bilirubin compared to the last quartile (highest bilirubin levels to determine the association of total serum bilirubin with UC. Similar to CD patients, UC patients demonstrated reduced levels of total serum bilirubin compared to controls at PSU and VCU. The lowest quartile of total serum bilirubin was independently associated with UC for the PSU (OR: 1.98 [95% CI: 1.09-3.63] and VCU cohorts (OR: 6.07 [95% CI: 3.01-12.75]. Lower levels of the antioxidant bilirubin may reduce the capability of UC patients to remove reactive oxygen species leading to an increase in intestinal injury. Therapeutics that reduce oxidative stress may be beneficial for these patients.

Fetuin-A is a glycoprotein secreted by liver and has been shown to inhibit extraosseous mineralization. Urolithiasis may be a manifestation in the urinary tract due to fetuin deficiency in urine. The objective of this study was to compare the 24-h urine and serum fetuin-A levels of patients with and without urolithiasis. Serum and 24-h urine fetuin-A levels were measured in 41 patients with bilateral, multiple, or recurrent urinary tract calculi (Group A) and 41 matched controls with no calculi (Group B). Fetuin levels were measured by enzyme linked immunosorbent assay. Serum and urine fetuin-A levels in the two groups were compared. The median (range) 24-h urine fetuin-A value in Group A was 11.9 (1.12-221) mg/day and in Group B was 37.7 (1.28-125) mg/day. This difference was statistically significant (Mann-Whitney test, P = 0.0169). The median (range) serum fetuin-A in Group A was 0.67 (0.05-2.68) g/L and in Group B was 0.99 (0.01-5.5) g/L. The difference between serum values in the two arms was not statistically significant (Mann-Whitney test, P = 0.1817). However, the serum creatinine-adjusted mean log serum fetuin and urine fetuin were significantly different in the two arms ( P = 0.003). The mean ± standard deviation (range) serum creatinine in Group A was 0.98 ± 0.25 (0.56-1.58) mg% and in Group B was 0.83 ± 0.16 (0.58-1.18) mg% (two sample t -test, P = 0.0031). Patients with urolithiasis have lower urine fetuin-A and creatinine-adjusted serum fetuin-A levels.

Radioimmunoassay of serum digoxin levels in digitalis intoxication

International Nuclear Information System (INIS)

Arendt, G.

1981-01-01

For 101 hospitalized patients where clinical symptoms of a glucosidine intoxication as a consequence of oral digoxin treatment were noted, serum digoxin levels were determined using a RIA kit of the Boehringer company (I-125 tracer, solid phase tube separation technique) on a fasted stomach prior to oral drug administration. An ECG was performed simultaneously and in addition kidney function parameters and electrolyte levels were determined. An anamnesis and clinical examination of the patients were also conducted. Interferences in the RIA method and gastro-intestinal illness resulting in changes in resorption behaviour were excluded. The group of patients showed collectively an average serum digoxin level of 2.9 +- 0.9 ng/ml with a range from 1.8 to 6.8 ng/ml, which was statistically significantly higher than the average value for 101 patients receiving long-term oral medication but without symptoms of glycosidine intoxication. According to the manufacture's specifications for the RIA kit, values > 2.0 ng/ml are considered as toxic, with values between 1.6 and 2.0 ng/mg falling into a ''grey zone''. A correlation was found between toxic serum values with changes in ECG pattern and subjective clinical symptoms of intoxication. A limitation of kidney function was responsible for the high serum glycoside levels in 62% of the patients. It was shown that the differing response of patients towards digitalis medication, above all in the case of long-term therapy, warrants an RIA determination of serum glycoside values in order to adjust the digoxin dose to individual requirements.

To investigate serum carcinoembryonic antigen (CEA) as a prognostic factor for rectal cancer patients receiving pre-operative chemoradiotherapy (CRT). Between 2000 and 2009, 138 patients with advanced rectal cancer receiving CRT before surgery at our hospital were retrospectively classified into 3 groups: pre-CRT CEA <6 ng/ml (group L; n = 87); pre-CRT CEA ≥ 6 ng/ml and post-CRT CEA <6 ng/ml (group H-L; n = 32); and both pre- and post-CRT CEA ≥ 6 ng/ml (group H-H; n = 19). CEA ratio (defined as post-CRT CEA divided by pre-CRT CEA), post-CRT CEA level and other factors were reviewed for prediction of pathologic complete response (pCR). Five-year disease-free survival (DFS) was better in groups L (69.0%) and H-L (74.5%) than in group H-H (44.9%) (p = 0.024). Pathologic complete response was observed in 19.5%, 21.9% and 5.3% of groups L, H-L and H-H respectively (p = 0.281). Multivariate analysis showed that ypN stage and pCR were independent prognostic factors for DFS and that post-CRT CEA level was independently predictive of pCR. As a whole, post-CRT CEA <2.61 ng/ml predicted pCR (sensitivity 76.0%; specificity 58.4%). For those with pre-CRT CEA ≥6 ng/ml, post-CRT CEA and CEA ratio both predicted pCR (sensitivity 87.5%, specificity 76.7%). In patients with pre-CRT serum CEA ≥6 ng/ml, those with “normalized” CEA levels after CRT may have similar DFS to those with “normal” (<6 ng/ml) pre-CRT values. Post-CRT CEA level is a predictor for pCR, especially in those with pre-CRT CEA ≥6 ng/ml

Full Text Available "nBackground: The annual amount of mortality in ESRD exceeds the expectation and represents the recent evidences of the inflammation as its etiology. The etiology of inflammation is not clearly known. Chronic inflammation is a dominant occurrence of ESRD which increases the risk of atherosclerosis, malnutrition and peripheral vascular disease. Inflammatory responses are orchestrated by cytokines. Some of the proinflammatory cytokines like IL-6 have a crucial role in this phenomenon. The IL-6 and its receptor activity is up regulated in ESRD patients and the increased level of IL-6 predicts cardiovascular mortality and morbidity in normal and CRF patients. This study devotes itself to determining the serum level of IL-6 and factors affecting it in patients undergoing chronic hemodialysis in Imam Khomeini Hospital which can represent the Iranian Society. By identifying factors affecting the serum level of IL-6 and high-risk patients we can provide treatment possibilities, a decrease in mortality and an improvement in its prognosis. "n"nMethods: In this study 42 patients in Imam Dialysis Center were chosen and their serum IL-6 levels were measured at 2 times at three month interval and at the same time blood sample analysis were done for the following: Alb CPR, Ca, P, PTH, TIBC, Ferritin, TG, Chol, LDL, HDL, Uric Acid, Hb, WBC and urea."n"nResults: The mean serum level of IL-6 in hemodialysis patients was 6.35±4.47pg/ml (minimum: 0.55, maximum: 18.25 with the normal range of 1.3±3.2pg/ml."n"nConclusions: The IL-6 level was higher than normal range in the 52% of the patients.

Measurements of the serum Vitamin B 12 concentrations of 49 black and 49 white healthy adults demonstrate a significantly higher mean serum Vitamin B 12 level in blacks when compared to whites. The reason for this difference appears to be genetic, although environmental factors may also be involved. It is suggested that clinical laboratories should establish their own separate reference values of serum Vitamin B 12 for blacks and whites in order to prevent misinterpretation of test results

Objective: To investigate a correlation between serum alkaline phosphatase level and body mass index in human subjects. Methods: The comparative cross-sectional study was carried out at the National Institute for Biotechnology and Genetic Engineering, Faisalabad, Pakistan, from April 2012 to June 2013. Blood serum alkaline phosphatase levels were estimated and the subjects were divided into three sub-groups on the basis of their body mass index: normal weight (<25kg/m2), overweight (25-27kg/m2) and obese (>27kg/m2) subjects. The serum samples were used for the estimation of clinically important biochemical parameters, using commercial kits on clinical chemistry analyser. Results: Of the 197 subjects, 97(49 percent) were obese and 100(51 percent) were non-obese. The serum alkaline phosphatase level increased in obese (214±6.4 IU/L) compared to the non-obese subjects (184.5±5 IU/L). Furthermore, a significant linear relationship (r=0.3;p-0.0001) was found between serum alkaline phosphatase and body mass index. Other biochemical variables were not correlated to the body mass index. Conclusion: Over activity and higher amounts of alkaline phosphatase were linked to the development of obesity. (author)

Mammographic density is a risk factor for breast cancer but the mechanism behind this association is unclear. The receptor activator of nuclear factor κB (RANK)/RANK ligand (RANKL) pathway has been implicated in the development of breast cancer. Given the role of RANK signaling in mammary epithelial cell proliferation, we hypothesized this pathway may also be associated with mammographic density. Osteoprotegerin (OPG), a decoy receptor for RANKL, is known to inhibit RANK signaling. Thus, it is of interest to evaluate whether OPG levels modify breast cancer risk through mammographic density. We quantified serum OPG levels in 57 premenopausal and 43 postmenopausal women using an enzyme-linked immunosorbent assay (ELISA). Cumulus was used to measure percent density, dense area, and non-dense area for each mammographic image. Subjects were classified into high versus low OPG levels based on the median serum OPG level in the entire cohort (115.1 pg/mL). Multivariate models were used to assess the relationship between serum OPG levels and the measures of mammographic density. Serum OPG levels were not associated with mammographic density among premenopausal women (P ≥ 0.42). Among postmenopausal women, those with low serum OPG levels had higher mean percent mammographic density (20.9% vs. 13.7%; P = 0.04) and mean dense area (23.4 cm 2 vs. 15.2 cm 2 ; P = 0.02) compared to those with high serum OPG levels after covariate adjustment. These findings suggest that low OPG levels may be associated with high mammographic density, particularly in postmenopausal women. Targeting RANK signaling may represent a plausible, non-surgical prevention option for high-risk women with high mammographic density, especially those with low circulating OPG levels.

The prognosis for patients with ductal adenocarcinoma of the pancreas (PDAC) remains poor even after curative resection. Carbohydrate antigen 19-9 (CA 19-9) and the carcinoembryonic antigen (CEA) are the most widely used serum-based tumor markers for the diagnosis and follow up of pancreatic cancer. In our analysis we aim to assess the prognostic value of a combination of both tumor markers in patients with pancreatic ductal adenocarcinoma (PDAC). Between 01/1995 and 08/2012 we performed a total of 264 pancreatic resections due to PDAC. Patients were stratified into 3 groups in regard to their preoperative tumor marker levels. Survival was compared between the groups using Kaplan Meier analysis and log rank test. Univariate subgroup analysis and multivariate analysis were performed. For 259 cases complete follow up could be obtained. In patients with low preoperative CEA and CA 19-9 levels (group 1 n = 91) the mean survival was 33.3 month (CI 95% 25.1-41.5). If one of the analyzed tumor markers (CEA/CA19-9) was preoperatively elevated above the cut-off level (group 2 n = 106) mean survival was 28.5 month (CI 95% 22.1-35.1). 62 patients showed preoperative elevation of both, CEA and CA 19-9 (group 3); mean survival in this group was 23.9 month (CI 95% 13.9-33.9), p > 0.01. Multivariate analysis confirmed preoperative CEA/CA 19-9 level as independent prognostic factor (HR 1.299). Preoperative CEA and CA 19-9 levels correlate with patient prognosis after curative pancreatic resection due to PDAC. This is especially true for the most frequently pT 3/4 stages of PDAC. Even if CEA and CA 19-9 might not be appropriate for screening, its serum levels should therefore be determined prior to operation and taken into account when resectability or operability is doubtful.

The causes of late-onset Alzheimer disease (AD) are not yet understood but likely include a combination of genetic, environmental, and lifestyle factors. Limited epidemiological studies suggest that occupational pesticide exposures are associated with AD. Previously, we reported that serum levels of dichlorodiphenyldichloroethylene (DDE), the metabolite of the pesticide dichlorodiphenyltrichloroethane (DDT), were elevated in a small number of patients with AD (n=20). To evaluate the association between serum levels of DDE and AD and whether the apolipoprotein E (APOE) genotype modifies the association. A case-control study consisting of existing samples from patients with AD and control participants from the Emory University Alzheimer's Disease Research Center and the University of Texas Southwestern Medical School's Alzheimer's Disease Center. Serum levels of DDE were measured in 79 control and 86 AD cases. Serum DDE levels, AD diagnosis, severity of AD measured by the Mini-Mental State Examination score, and interaction with APOE4 status. Levels of DDE were 3.8-fold higher in the serum of those with AD (mean [SEM], 2.64 [0.35] ng/mg cholesterol) when compared with control participants (mean [SEM], 0.69 [0.1] ng/mg cholesterol; P risk for AD (95% CI, 2.54-5.82; P risk for AD and carriers of an APOE4 ε4 allele may be more susceptible to the effects of DDE. Both DDT and DDE increase amyloid precursor protein levels, providing mechanistic plausibility for the association of DDE exposure with AD. Identifying people who have elevated levels of DDE and carry an APOE ε4 allele may lead to early identification of some cases of AD.

To investigate the relationship between serum total testosterone (TT) and free testosterone (FT) levels in men with anemia. We reviewed the records of 1221 subjects between March 2009 and December 2014. All the subjects' blood samples were drawn for TT and FT assays. Their serum hemoglobin (Hb) and serum hematocrit (Hct) levels were measured. The primary objective of our study was to investigate the association between TT and FT levels with Hb and Hct levels. The mean age was 59.82 ± 12.71 years. The mean TT and FT levels were 4.54 ± 2.02 ng/mL and 10.63 ± 3.69 pg/mL, respectively. The mean Hb and Hct levels were 14.72 ± 1.34 g/dL and 43.11 ± 3.75%, respectively. Subjects with low TT (<2.35 ng/mL) had low Hb and Hct levels (p < 0.001, p < 0.001, respectively). TT was positively associated with FT, Hb, and Hct. TT and FT levels were significantly lower in older men. Subjects with low TT and FT levels had low Hb and Hct levels. This suggests that TT and FT play a significant role in erythropoiesis. Testosterone replacement therapy may be effective in men with hypogonadism to reduce the incidence of anemia.

The systemic absorption of copper incorporated into multiload intra-uterine contraceptive devices (IUDs), as indicated by serum copper levels in users of such devices, was assessed in a prospective longitudinal study. One hundred and ten healthy Nigerian women using either multiload copper 250 (MLCU 250) or multiload copper 375 (MLCU 375) IUDs participated in the study. Their serum copper levels were estimated serially during 12 months of continuous use of the devices. The mean (+/- s.e.m.) pre-insertion serum copper levels of our subjects using MLCU 250 (17.0 +/- 3 mumol/l) and MLCU 375 (16.7 +/- 0.5 mumol/l) were found to be lower than those reported in Americans (22.2 mumol/l) and in Germans (20.2 mumol/l), although similar to levels in Indians (17.0 mumol/l). There was no significant difference in the mean serum copper levels estimated before and after 1 month of continuous use of the device. Serial estimations of the serum copper levels in users showed that there was no alteration in these levels after a period of 12 months of continuous IUD use. We therefore conclude that the copper incorporated into multiload IUDs appears not to influence the concentration of serum copper of users.

Full Text Available INTRODUCTION Gallstones are one of the most common problem associated with the gallbladder, affecting millions of people throughout the world. Bile is excreted from liver and gallbladder into Duodenum for digestion. After digestion, if the gallbladder is not emptied out completely, the Bile Juice that remains in the gallbladder can become too concentrated with cholesterol leading to gallstone formation. Cholesterol and calcium bilirubinate are the two main substances involved in gallstone formation. Gallstones derived from bile consists of mixture of cholesterol, bilirubin with or without calcium. Based on their chemical composition, gallstones found in the gallbladder are classified as cholesterol, pigmented or mixed stones. Iron deficiency has been shown to alter the activity of several hepatic enzymes, leading to increased gallbladder bile cholesterol saturation and promotion of cholesterol crystal formation. AIMS & OBJECTIVE Attempt to establish a correlation with gallstones and decreased serum iron levels. MATERIAL & METHODS This study was a prospective cohort study which included 100 consecutive patients with imaging studies suggestive of Cholelithiasis. The Gallstone surgically removed was crushed with mortar and pestle and then analysed for cholesterol, calcium, phosphate and bilirubin (pigment. Serum samples were analysed for Cholesterol, iron and iron binding capacity. RESULTS 86% patients had increased cholesterol levels (p=0.04 and 93% had decreased serum Iron levels (p=0.96. The most common type of gallstone was found to be Cholesterol type of gallstone followed by Mixed and Pigment gallstones. CONCLUSION Serum cholesterol levels were found to be raised in majority of the patients and serum iron was found to be low in these majority of the patients indicating iron deficiency may play a role in gallstone formation.

Preclinical and clinical studies show associations between testosterone and brain-derived neurotrophic growth factor (BDNF) serum levels. BDNF and testosterone have been independently reported to influence alcohol consumption. Therefore, we aimed to investigate a possible interplay of testosterone and BDNF contributing to alcohol dependence. Regarding possible interplay of testosterone and BDNF and the activity of the hypothalamic pituitary axis (HPA), we included cortisol serum levels in our research. We investigated testosterone and BDNF serum levels in a sample of 99 male alcohol-dependent patients during alcohol withdrawal (day 1, 7, and 14) and compared them to a healthy male control group (n = 17). The testosterone serum levels were significantly (p BDNF serum levels (day 1: p = 0.008). In a subgroup of patients showing high cortisol serum levels (putatively mirroring high HPA activity), we found a significant association of BDNF and testosterone as well as with alcohol craving measured by the Obsessive and Compulsive Drinking Scale (OCDS). Our data suggest a possible association of BDNF and testosterone serum levels, which may be relevant for the symptomatology of alcohol dependence. Further studies are needed to clarify our results.

To determine the influence of exercise on serum levels of myoglobin, serum levels of this protein were determined by RIA in 90 healthy men, divided as follows: (1) Basal control (no exercise) 25 cases; (2) Moderate exercise (after subject had been working for 12 h in Medicine Emergency Service) 19 cases, and (3) Intensive exercise: (a) football professional (45-min match) 10 cases; (b) football amateur (45-min match) 10 cases; (c) basketball professional (45-min match) 10 cases, and (d) basketball professional (90-min training) 16 cases. Our results led us to the following conclusions. (1) Moderate exercise, such as the usual daily work, does not modify myoglobin levels; (2) Myoglobin serum levels after exercise increase in nearly all individuals. They are higher in untrained people; (3) There seems to be a correlation between exercise intensity and increase of myoglobin serum levels, and (4) The detection of serum myoglobin by RIA may have a wide field of application for sport medicine.

In order to study the serum osteocalcin (OC) level in hyperthyroidism, serum osteocalcin, FT 3 , FT 4 and TSH were measured by radioimmunoassay in 87 patients with hyperthyroidism and 52 healthy volunteers. The results indicated that the serum osteocalcin level was decreased with age increasing in healthy volunteers and there was no significant difference in sex (P > 0.05). Serum concentration of OC was significantly higher in untreated hyperthyroid patients than that in healthy volunteers (P 3 , FT 4 (FT 3 :r 0.84 - 0.27, P 4 :r = 0.58 - 0.29, P < 0.01), but not with TSH. Conclusion: Thyroid hormones might speed up bone turnover directly with increased bone resorption to induce bone mass loss. These results indicate that OC is a highly sensitive marker for altered bone metabolism in hyperthyroidism

This article describes the factors that motivated the nursing staff of the cardiac surgery unit at the Royal Victoria Hospital in Montreal, to revise their preoperative teaching program. The motivating factors described are the length of the preoperative waiting period; the level of preoperative anxiety; the decreased length of hospital stay; the dissatisfaction of the nursing staff with current patient teaching practices; and the lack of available resources. The reorganization of the teaching program was based upon the previously described factors combined with a review of the literature that demonstrated the impact of preoperative anxiety, emotional support and psycho-educational interventions upon the client's recovery. The goals of the new teaching program are to provide the client and the family with cognitive and sensory information about the client's impending hospitalization, chronic illness and necessary lifestyle modifications. The program consists of a system of telephone calls during the preoperative waiting period; a videotape viewing; a tour of the cardiac surgery unit; informal discussion groups; and the availability of nursing consultation to decrease preoperative anxiety. The end result of these interventions is more time for client support and integration of necessary information by the client and family. This kind of program has the potential to provide satisfaction at many levels by identifying client's at risk; increasing client knowledge; increasing support; decreasing anxiety during the preoperative waiting period; and decreasing the length of hospital stay. The nursing staff gained a heightened sense of accomplishment because the program was developed according to the nursing department's philosophy, which includes primary nursing.(ABSTRACT TRUNCATED AT 250 WORDS)

Serum Renalase Levels Correlate with Disease Activity in Lupus Nephritis.

Full Text Available Lupus nephritis (LN is among the most serious complications of systemic lupus erythematosus (SLE, which causes significant morbidity and mortality. Renalase is a novel, kidney-secreted cytokine-like protein that promotes cell survival. Here, we aimed to investigate the relationship of serum renalase levels with LN and its role in the disease progression of LN.For this cross-sectional study, 67 LN patients and 35 healthy controls were enrolled. Seventeen active LN patients who received standard therapies were followed up for six months. Disease activity was determined by the SLE Disease Activity-2000 (SLEDAI-2K scoring system and serum renalase amounts were determined by ELISA. Predictive value of renalase for disease activity was assessed. Furthermore, the expression of renalase in the kidneys of patients and macrophage infiltration was assessed by immunohistochemistry.Serum renalase amounts were significantly higher in LN patients than in healthy controls. Moreover, patients with proliferative LN had more elevated serum renalase levels than Class V LN patients. In proliferative LN patients, serum renalase levels were significantly higher in patients with active LN than those with inactive LN. Serum renalase levels were positively correlated with SLEDAI-2K, 24-h urine protein excretion, ds-DNA and ESR but inversely correlated with serum albumin and C3. Renalase amounts decreased significantly after six-months of standard therapy. The performance of renalase as a marker for diagnosis of active LN was 0.906 with a cutoff value of 66.67 μg/ml. We also observed that the amount of renalase was significantly higher in glomerular of proliferative LN along with the co-expression of macrophages.Serum renalase levels were correlated with disease activity in LN. Serum renalase might serve as a potential indicator for disease activity in LN. The marked increase of glomerular renalase and its association with macrophages suggest that it might play an

Summary Background: We aimed to compare ghrelin, obestatin, homocysteine (Hcy), vitamin B12 and folate levels in the serum and saliva of ischaemic heart disease patients. Methods: Serum and saliva were collected from 33 ischaemic heart disease (IHD) patients and 28 age- and body mass index-matched healthy individuals. Levels of acylated and desacylated ghrelin, obestatin and Hcy were determined using the ELISA method. Results: Acylated ghrelin, desacylated ghrelin and obestatin levels in the saliva were found to be higher than those in the serum of the control group, while acylated and desacylated ghrelin levels in the saliva were significantly lower than those in the serum. Obestatin levels were higher in IHD patients (p = 0.001). Saliva and serum vitamin B12 and folate levels in IHD patients were significantly lower than in the control group (p = 0.001). Conclusions: It was determined that serum ghrelin levels increased in ischaemic heart disease patients, while serum levels of obestatin decreased. PMID:28759087

Objective: To investigate the possible relationship existing between serum sex hormones levels and development of essential hypertension. Methods: Serum sex hormones (LH, FSH, E 2 , P, T) levels were determined with RIA in 87 males and 81 post-menopausal women with essential hypertension as well as in 44 normotensive males and 40 normotensive post-menopausal women serving as controls. Results: The serum E 2 , progesterone and testosterone levels in the hypertensives were significantly higher than those in the respective controls (P 0.05). Sex hormones levels were not much different among hypertensives of various stages (I , II, III). The serum E 2 levels in male hypertensives and progesterone levels in female hypertensives were not correlated with the respective FSH and LH levels. Conclusion: The authors suggested that the changes of serum sex hormones levels might be a risk factor rather than a consequence of the development of essential hypertension. (authors)

Full Text Available Introduction : Vitiligo is a common acquired pigmentary skin disorder. Vitamin D is responsible for skin pigmentation, increases tyrosinase activity and melanogenesis, and exhibits immunoregulatory functions. Low levels of vitamin D are associated with many autoimmune diseases, including systemic lupus, diabetes mellitus, rheumatoid arthritis, multiple sclerosis and alopecia areata. Few reports have evaluated serum vitamin D levels in vitiligo patients, and their results are conflicting. Aim : To evaluate serum vitamin D levels of vitiligo patients and compare the results with controls. Material and methods : In total, 50 vitiligo patients and 47 controls were enrolled in the study. Vitamin D levels were measured from blood samples. Group comparisons were performed using appropriate statistical methods. Results : The patients had lower serum vitamin D levels than the controls, but this difference was not significant (p = 0.570. Conclusions : It remains unknown whether vitamin D deficiency causes vitiligo. Larger controlled studies are required to prove whether low circulating vitamin D is a causative factor in vitiligo.

Serum Albumin Levels and Economic Status in Japanese Older Adults.

Directory of Open Access Journals (Sweden)

Asami Ota

Full Text Available Low serum albumin levels are associated with aging and medical conditions such as cancer, liver dysfunction, inflammation, and malnutrition and might be an independent predictor of long-term mortality in healthy older populations. We tested the hypothesis that economic status is associated with serum albumin levels and explained by nutritional and health status in Japanese older adults.We performed a cross-sectional analysis using data from the Japan Gerontological Evaluation study (JAGES. The study participants were 6528 functionally independent residents (3189 men and 3339 women aged ≥65 years living in four municipalities in Aichi prefecture. We used household income as an indicator of economic status. Multiple linear regression was used to compare serum albumin levels in relation to household income, which was classified as low, middle, and high. Additionally, mediation by nutritional and health-related factors was analyzed in multivariable models.With the middle-income group as reference, participants with low incomes had a significantly lower serum albumin level, even after adjustment for sex, age, residential area, education, marital status, and household structure. The estimated mean difference was -0.17 g/L (95% confidence interval, -0.33 to -0.01 g/L. The relation between serum albumin level and low income became statistically insignificant when "body mass index", "consumption of meat or fish", "self-rated health", "presence of medical conditions", "hyperlipidemia", or "respiratory disease "was included in the model.Serum albumin levels were lower in Japanese older adults with low economic status. The decrease in albumin levels appears to be mediated by nutrition and health-related factors with low household incomes. Future studies are needed to reveal the existence of other pathways.

Serum thymus and activation-regulated chemokine (TARC) levels are associated with the disease activity of patients with atopic dermatitis (AD) and sensitively reflect short-term changes in skin conditions. The main treatment for AD is topical agent application. This study investigated the relationship between serum TARC levels and the dosage of topical agents, including corticosteroids and/or tacrolimus, in patients with AD. The serum TARC levels of 56 AD patients and the amounts of topical agents prescribed to them were investigated retrospectively. The weekly reduction in serum TARC levels and weekly dosage of topical agents among AD patients were compared and their associations were evaluated. The dosage of topical agents was closely related to serum TARC levels. One gram of strong rank steroid or the equivalent amount of steroid/tacrolimus is required to reduce serum TARC levels by 9.94 pg/mL weekly in moderate to severe AD patients. Higher initial TARC levels require more topical agent, which results in a more rapid decrease in TARC levels. The serum TARC levels and eosinophil numbers in peripheral blood are significantly correlated. Serum TARC level improvement and topical agent dosage are strongly correlated. TARC and eosinophil numbers are significantly correlated, but the wider range of TARC levels seems to be clinically more useful for monitoring AD severity. The serum TARC level is a very sensitive biomarker for monitoring the severity and treatment response in AD.

Background and Purpose Bronchial asthma (BA) is a chronic airway disease characterized by airway hyperresponsiveness and remodeling, which are intimately linked to chronic airway inflammation. Reactive oxygen species (ROS) such as hydrogen peroxide are generated by inflammatory cells that are involved in the pathogenesis of BA. However, the role of ROS in the management of BA patients is not yet clear. We attempted to determine the role of ROS as a biomarker in the clinical setting of BA. Subjects and Methods We enrolled patients with BA from 2013 through 2015 and studied the degrees of asthma control, anti-asthma treatment, pulmonary function test results, fractional exhaled nitric oxide (FeNO), serum reactive oxygen metabolite (ROM) levels, and serum levels of interleukin (IL)-6 and IL-8. Results We recruited 110 patients with BA. Serum ROM levels correlated with white blood cell (WBC) count (rs = 0.273, p = 0.004), neutrophil count (rs = 0.235, p = 0.014), CRP (rs = 0.403, p < 0.001), and IL-6 (rs = 0.339, p < 0.001). Serum ROM levels and IL-8 and CRP levels negatively correlated with %FEV1 (rs = -0.240, p = 0.012, rs = -0.362, p < 0.001, rs = -0.197, p = 0.039, respectively). Serum ROM levels were significantly higher in patients who experienced severe exacerbation within 3 months than in patients who did not (339 [302–381] vs. 376 [352–414] CARR U, p < 0.025). Receiver-operating characteristics analysis showed that ROM levels correlated significantly with the occurrence of severe exacerbation (area under the curve: 0.699, 95% CI: 0.597–0.801, p = 0.025). Conclusions Serum levels of ROM were significantly associated with the degrees of airway obstruction, WBC counts, neutrophil counts, IL-6, and severe exacerbations. This biomarker may be useful in predicting severe exacerbations of BA. PMID:27776186

IMPORTANCE The causes of late-onset Alzheimer disease (AD) are not yet understood but likely include a combination of genetic, environmental, and lifestyle factors. Limited epidemiological studies suggest that occupational pesticide exposures are associated with AD. Previously, we reported that serum levels of dichlorodiphenyldichloroethylene (DDE), the metabolite of the pesticide dichlorodiphenyltrichloroethane (DDT), were elevated in a small number of patients with AD (n=20). OBJECTIVE To evaluate the association between serum levels of DDE and AD and whether the apolipoprotein E (APOE) genotype modifies the association. DESIGN, SETTING, AND PARTICIPANTS A case-control study consisting of existing samples from patients with AD and control participants from the Emory University Alzheimer’s Disease Research Center and the University of Texas Southwestern Medical School’s Alzheimer’s Disease Center. Serum levels of DDE were measured in 79 control and 86 AD cases. MAIN OUTCOMES AND MEASURES Serum DDE levels, AD diagnosis, severity of AD measured by the Mini-Mental State Examination score, and interaction with APOE4 status. RESULTS Levels of DDE were 3.8-fold higher in the serum of those with AD (mean [SEM], 2.64 [0.35] ng/mg cholesterol) when compared with control participants (mean [SEM], 0.69 [0.1] ng/mg cholesterol; P risk for AD (95% CI, 2.54–5.82; P risk for AD and carriers of an APOE4 ε4 allele may be more susceptible to the effects of DDE. Both DDT and DDE increase amyloid precursor protein levels, providing mechanistic plausibility for the association of DDE exposure with AD. Identifying people who have elevated levels of DDE and carry an APOE ε4 allele may lead to early identification of some cases of AD. PMID:24473795

Full Text Available "nBackground: Maternal zinc deficiency during pregnancy has been related to adverse pregnancy outcomes. Most studies in which pregnant women have been supplemented with zinc to examine its effects on the outcome of the pregnancy have been carried out in industrialized countries and the results have been inconclusive. It has been shown that women with gestational diabetes (GDM have lower serum zinc levels than healthy pregnant women, and higher rates of macrosomia. Zinc is required for normal glucose metabolism, and strengthens the insulin-induced transportation of glucose into cells by its effect on the insulin signaling pathway. The purpose of this study was to assess the serum zinc levels of GDM patients and evaluate the effect of zinc supplementation. "nMethods: In the first stage of this prospective controlled study, we enrolled 70 women who were 24-28 weeks pregnant at the Prenatal Care Center of Mirza Kochak Khan Hospital, Tehran, Iran. The serum zinc level of each subject was determined. In the second stage, among these 70 subjects, the diabetics receiving insulin were divided into two groups, only one of which received a zinc supplement and the other group was the control group. Birth weight of neonates and insulin dosages were recorded. "nResults: The mean serum zinc level in the GDM group was lower than that of the control group (94.83 vs. 103.49mg/dl, respectively and the mean birth weight of neonates from the GDM women who received the zinc supplement was lower than that of the control group (3849g vs. 4136g. The rate of macrosomia was lower in the zinc supplemented group (20% vs. 53%. The mean of increase of insulin after receiving the zinc supplement was lower (8.4u vs. 13.53. "nConclusion: Maternal insulin resistance is associated with the accumulation of maternal fat tissue during early stages of pregnancy and greater fetoplacental nutrient availability in later stages, when 70% of fetal growth occurs, resulting in macrosomia.

Chalazion is a chronic, localized lipogranulomatous inflammation of the sebaceous glands of the lids. Chalazion occurs often secondary to blockage of the sebaceous gland ducts. Some studies have reported vitamin A deficiency as a risk factor for chalazion. In this study, we determined the serum levels of vitamin A in patients with chalazion. The study involved a total of 107 subjects (52 patients with chalazion and 55 control healthy subjects). The study was conducted at the Ophthalmology Clinics of Imam Khomeini Hospital, Ahwaz Jundishapur University of Medical Sciences, Ahwaz, Iran between September 2014 and February 2015. The subjects were divided into three groups according to age: 7-12 years old, 13-19 years old, and more than 19 years old. Patients were further divided into four subgroups based on the type of chalazion: single, multiple, primary, and recurrent. Blood samples were collected and the serum was tested for levels of vitamin A using high-performance liquid chromatography (HPLC). The average serum vitamin A levels in patients with chalazion in the age groups of 7-12 and 13-19 years were significantly lower than in their control counterparts. Serum vitamin A levels in patients with recurrent, multiple chalazia were significantly lower than in patients with primary, multiple chalazia (P = 0.026) and patients with a recurrent, single chalazion (P = 0.029). In conclusion, chalazion could be one of the ocular presentations of vitamin A deficiency.

Serum immunoglobulins (SI) were determined in 803 survivors and matched controls. Each subject's age, sex, health, exposure, and medical record were evaluated with respect to serum IgG, IgA, IgM levels. The IgG and IgA levels tended to be higher for this Hiroshima population than for Americans. Past exposure to ionizing radiation showed no significant correlation to SI levels. However, age and sex did influence the SI. IgM was significantly higher in females. With advancing age IgG and IgA increased in males, and IgM decreased in females. Elevated sedimentation rate and increased lymphocytes were accompanied by increased SI levels. Radiographic TB was detected in 45% of the population; IgG and IgA levels were somewhat elevated in these individuals. (DLC)

Full Text Available Background. Serum ghrelin levels may be related to metabolic and clinical changes in patients with psoriasis. Objective. This study was performed to determine the possible effects of serum ghrelin in patients with psoriasis. Methods. The study population consisted of 25 patients with plaque psoriasis. The patients were questioned with regard to age, gender, age of onset, duration of disease, height, weight, and body mass index (BMI. In addition, fasting blood sugar, triglyceride, cholesterol levels, insulin, and ghrelin levels were measured. Results. The mean serum ghrelin level was 45.41 ± 22.41 in the psoriasis group and 29.92 ± 14.65 in the healthy control group. Serum ghrelin level was significantly higher in the psoriasis group compared with the controls (P=0.01. The mean ghrelin level in patients with a lower PASI score was significantly higher than in those with a higher PASI score (P=0.02. Conclusion. The present study was performed to determine the effects of ghrelin in psoriasis patients. We found a negative correlation between severity of psoriasis and ghrelin level. Larger and especially experimental studies focusing on correlation of immune system-ghrelin levels and severity of psoriasis may be valuable to clarify the etiopathogenesis of the disease.

Full Text Available Fetuin-A is a calcification inhibitor, negative acute phase response marker and cardiovascular mortality predictor in hemodialysis patients. Low levels of fetuin-A are associated with malnutrition, inflammation, decreased bone mass density, low-turnover bone and use of high calcium concentration dialysate. Hemodialysis procedure (HD has been shown to decrease fetuin-A levels by 20%, probably due to HD-induced inflammation or acute changes in calcium metabolism. The aim of our study was to investigate effects of HD on serum fetuin-A levels. Forty clinically and hemodynamically stable hemodialysis patients (21 females, 68 (38-85 years underwent routine bicarbonate hemodialysis or hemodiafiltration with polysulfone dialyzer. On consecutive HD dialysis solution with different calcium concentration with/without citric acid was used to assess influence of calcium shifts and parathyroid activity on fetuin-A changes during HD. All other parameters of HD were kept constant. Serum fetuin-A, calcium, phosphorus, iPTH, CRP and other biochemical parameters were measured before and after each HD. Our data show that predialysis serum fetuin-A levels have positive correlation with iPTH levels (p<0.05 and tendency to decrease with higher CRP levels. There was no change in fetuin-A levels during HD: 206 (167.1; 231.9 ug/ml before and 208.9 (170.3; 246.3 ug/ml after HD; respectively. When corrected for haemoconcentration, decrease in fetuin-A was only 2.8% (p<0.05. There was also no difference between effect of hemodialysis and hemodia-filtration procedure. The use of different calcium dialysate concentrations had distinct effect on iPTH levels during and after HD, however, we observed no associated changes in fetuin-A levels. The use of dialysate solution with citric acid had no effect on fetuin-A levels. In conclusion, standard bicarbonate HD with polysulfone dialyser and ultrapure dialysate induces only minor changes in fetuin-A and no changes in hsCRP levels

Serum carnitine is decreased in recurrent pulmonary infections. We aimed to evaluate serum carnitine levels in asthmatic children. Study group consisted of children with stable asthma and those with acute asthma attacks, while control group included healthy children. Attack severity was determined by the pulmonary score system. Total and free carnitine levels were studied in one blood sample from the control group and stable asthmatics and in two samples from children with acute asthma exacerbation during and after the attack. All the 40 patients in the study group had moderate asthma including 30 with acute attack (13 mild and 17 moderate) and 10 with stable asthma. Carnitine levels were significantly lower in acute attack asthmatics than in the stable asthmatics and controls, while there was no significant difference between the latter two groups. Carnitine levels were not different between asthmatics with mild and moderate attack, and were similar during and after an acute attack. Serum carnitine levels decrease in children with moderate asthma during exacerbation of asthma and shortly thereafter. Further studies are needed to evaluate the effect of carnitine treatment on serum carnitine level.

We studies a relationship between the serum levels of thrombomodulin(TM) and the thyroid functions. Serum TM levels were measured in 48 patients with Graves' disease, 17 patients with primary hypothyroidism, 7 patients with subacute thyroiditis, 5 patients with painless thyroiditis and 2 patients with systematic Refetoff syndrome. These patients did not have malignant tumor, kidney failure, or blood vessel injury. Control sera were obtained from 42 healthy subjects. Serum levels of TM in patients with untreated Graves' disease were significantly higher(p thyroid function(FT3, FT4 and TH) in patients with Graves' disease during treatment showed that both the serum levels of TM and thyroid hormones (FT3 and FT4) lowered progressively during treatment. After normalization of serum FT3 and FT4, the serum TM levels returned to normal. However, the serum levels of TM in patients with destructive thyroiditis and Refetoff syndrome were normal in spite of high serum levels of thyroid hormones. These data suggest that an increase in serum levels of TM is not the direct result of thyroid hormones themselves but is the result of the prolonged hypermetabolic state induced by their peripheral activities. Thyroid hormones may stimulate the synthesis or metabolism of TM on the surface of vascular endothelial cells in the patients with Graves' disease.

Introduction: Polychlorobiphenyls (PCBs) are persistent pollutants that are widespread in the environment and in foodstuffs, particularly in freshwater fish, which frequently exceed the maximum levels set by European regulations. Objectives: First, we describe the consumption of freshwater fish and serum PCB levels in French anglers, a population expected to have the highest level of dietary PCB exposure. Second, we investigated whether there is a statistical relationship between serum PCB levels and the angler consumption of freshwater fish with high PCB bioaccumulation potential (PCB-BP + freshwater fish) in order to make recommendations with regard to safe consumption of freshwater fish. Methods: We conducted a survey of anglers from six sites with contrasting PCB contamination levels. The survey included a food consumption frequency questionnaire and blood samples were taken to assess serum PCB levels. We used a regression model to determine the main factors contributing to serum PCB levels. Results: Consumption of PCB-BP + freshwater fish was relatively infrequent. Serum PCB levels of the study population and of women of childbearing age were in the same range as those observed in the French population and in neighbouring European countries, but higher than in the North American population. The two factors with the highest positive association with serum PCB levels were age (R 2 = 61%) and the consumption of PCB-BP + freshwater fish (R 2 = 2%). Using the regression model, we calculated, for several scenarios depending on the age and gender of the population, the maximum annual frequencies for PCB-BP + freshwater fish consumption that do not exceed the critical body burden threshold. Conclusion: Following the results of this study, the French agency for food, environmental and occupational health and safety (ANSES) issued an opinion and recommended some specific maximum freshwater fish consumption frequencies to protect the French general population

Objective: To study the effect of splenectomy on serum β-amyloid (Aβ) levels in rabbit. Methods: Thirty 3yr-old rabbits underwent splenectomy and fifteen others underwent a sham-operation of laparectomy only. Serum Aβ levels were determined with RIA before and at regular intervals after operation. Results: In the splenectomy group, the Aβ levels were increased greatly after the operation and reached the peak at 5 th week. The levels then gradually declined but remained significantly higher than the pre-operative value at 6 th month. In the sham operation group, the value was no drastically changed but increased slowly (as an aging process). Conclusion: Splenectomy in rabbit would markedly increase the serum Aβ level, possibly due to a hypoimmune state impairing clearance of the substance

Full Text Available Aim To compare plasma IL-10 concentrations in patients with Acute Coronary Syndrome (ACS with those in Coronary Artery Disease (CAD.Methods ACS patients hospitalized in intensive coronary care unit (ICCU of Cipto Mangunkusumo Hospital/Faculty of Medicine University of Indonesia (CMH/FMUI, Persahabatan Hospital, MMC Hospital, and Medistra Hospital, Jakarta, between May 2005 and May 2006, were included in this study. The ambulatory CAD patients were taken as comparator. The serum IL-10 level was measured by immunoassay method, and compared by using Independent Student’s t-test. To investigate whether IL-10 serum level could predict ACS, the sensitivity and specificity of this parameter towards ACS in various IL-10 serum levels were calculated as well.Results In this observational study, as many as 146 subjects were analyzed, consisting of 84 ACS patients, and 62 coronary artery disease (CAD. The IL-10 level was higher in the group of ACS patients (7.37 pg/mL + 7.81, CI 95% 5.68-9.07 than that in CAD patients (1.59 pg/mL + 1.55, CI 95% 1.2-1.98. The optimal cut-off point for serum IL-10level is >1.95 pg/mL, with 79.76 % sensitivity and 77.42 % specificity.Conclusion The IL-10 level was higher in the ACS patients compared to that in CAD patients. Serum IL-10 measurement is a quite superior method to distinguish acute and stable condition, eventhough it is not as good as hsCRP for the same purpose.

To investigate the effect of preoperative Lugol's iodine on intraoperative bleeding in patients with hyperthyroidism. This controlled, randomized, prospective cohort was carried out on 40 patients who admitted for surgery due to hyperthyroidism. Cases were randomly assigned to receive either preoperative treatment with Lugol solution (Group 1) or no preoperative treatment with Lugol solution (Group 2). Group 3 (n = 10) consisted of healthy adults with no known history and signs of hyperthyroidism. Blood flow through the thyroid arteries of patients was measured by color flow Doppler ultrasonography. Free T3, free T4, TSH, thyroid volume and the resistance index of the four main thyroid arteries were measured in all patients. There was not a significant difference between gender, preoperative serum thyroid hormone levels, or thyroid gland volumes between groups 1 and 2. The mean blood flow of the patients in Group 1 was significantly lower than values in Group 2. When age, gender, thyroid hormone, TSH, thyroid volume, blood flow, and Lugol solution treatment were included as independent variables, Lugol solution treatment (OR, 7.40; 95% CI, 1.02-58.46; p = 0.001) was found to be the only significant independent determinant of intraoperative blood loss. Lugol solution treatment resulted in a 7.40-fold decrease in the rate of intraoperative blood loss. Preoperative Lugol solution treatment was found to be a significant independent determinant of intraoperative blood loss. Moreover, preoperative Lugol solution treatment decreased the rate of blood flow, and intraoperative blood loss during thyroidectomy.

To examines the potential causes of increased levels of calcium in serum with increasing dose of atomic bomb radiation, which was obtained from the previous preliminary analysis, levels of parathyroid hormone (PTH) and calcitonin in serum were examined among 1459 subjects in Hiroshima and Nagasaki. A significant effect of radiation on levels of calcium, PTH and calcitonin in serum was found, even after patients with hyperparathyroidism were excluded. The level of calcium in serum increased with radiation dose; this can be explained partly by the increase in the level of PTH with radiation dose. However, the dose effect on calcium remained even after adjustment for PTH, calcitonin and confounding factors such as renal function, serum albumin level and medication. Parathyroid hormone increased initially by 6.8% per gray, but the dose response leveled off after about 1 Gy. The level of calcitonin increased with radiation dose, probably in part due to feedback mechanisms stimulated by the increase in calcium. However, after adjustment for the level of calcium, the increase in the level of calcitonin with dose was still found. Although the etiological mechanisms of the effect of radiation on serum levels of calcium, PTH and calcitonin are unclear, radiation exposure may affect secretion of PTH and calcitonin and regulation of calcium a long time after atomic bomb exposure. 21 refs., 3 figs., 6 tabs

Objective. Recent data suggest that fetal antigen (FA1) is linked to disorders of body weight. Thus, we measured FA1 serum levels in two extreme nutritional states of morbid obesity (MO) and anorexia nervosa (AN) and monitored its response to weight changes. Design. FA1 and insulin serum concentrations were assessed in a cross-sectional study design at defined time points after gastric restrictive surgery for 25 MO patients and 15 women with AN. Results. Absolute FA1 serum levels were within the assay normal range and were not different between the groups at baseline. However, the ratio of FA1/BMI was significantly higher in AN. FA1 was inversely correlated with BMI before and after weight change in AN, but not in MO patients. In addition, MO patients displayed a significant concomitant decrease of FA1 and insulin with the first 25% of EWL, while in AN patients a significant increase of FA1 was observed in association with weight gain. Conclusion. FA1 is a sensitive indicator of metabolic adaptation during weight change. While FA1 serum levels in humans generally do not correlate with BMI, our results suggest that changes in FA1 serum levels reflect changes in adipose tissue turnover. PMID:22844611

Full Text Available Abstract Background There is mounting evidence that estimates of intakes of a range of dietary nutrients are related to both lung function level and rate of decline, but far less evidence on the relation between lung function and objective measures of serum levels of individual nutrients. The aim of this study was to conduct a comprehensive examination of the independent associations of a wide range of serum markers of nutritional status with lung function, measured as the one-second forced expiratory volume (FEV1. Methods Using data from the Third National Health and Nutrition Examination Survey, a US population-based cross-sectional study, we investigated the relation between 21 serum markers of potentially relevant nutrients and FEV1, with adjustment for potential confounding factors. Systematic approaches were used to guide the analysis. Results In a mutually adjusted model, higher serum levels of antioxidant vitamins (vitamin A, beta-cryptoxanthin, vitamin C, vitamin E, selenium, normalized calcium, chloride, and iron were independently associated with higher levels of FEV1. Higher concentrations of potassium and sodium were associated with lower FEV1. Conclusion Maintaining higher serum concentrations of dietary antioxidant vitamins and selenium is potentially beneficial to lung health. In addition other novel associations found in this study merit further investigation.

To investigate the prognostic value of tumor markers, cancer antigen 15-3 (CA 15-3) and carcinoembryonic antigen (CEA) levels at diagnosis of systemic recurrence. After primary treatments of locoregional breast cancers, serum CA 15-3 and/or CEA concentrations were regularly measured, and systemic recurrences were identified in 351 patients between January 1999 and December 2009. The association between tumor marker levels at systemic recurrence and survival were investigated by univariate and multivariate analyses. Elevated CA 15-3 and CEA levels were identified in 194 of 349 (55.6 %) and 111 of 308 (36.0 %) patients, respectively, at diagnosis of systemic recurrence. Elevated levels of CA 15-3 and CEA were correlated with visceral or multiple recurrences and elevated preoperative levels. Elevation of CA 15-3 was more prominent in younger patients and in primary node-positive tumors, while CEA was elevated in older patients at diagnosis and in estrogen receptor (ER)-positive tumors. Elevated tumor markers as well as ER negativity, short disease-free interval, and advanced stage at initial diagnosis showed independent prognostic significance on multivariate analysis. Among 306 patients for whom levels of both tumor markers at recurrence were available, 106 patients without elevation of either marker showed significantly better overall survival than those with elevated levels of either one or both markers, and the significance persisted in multivariate analysis. Elevated serum CA 15-3 and CEA levels at recurrence suggest increased tumor burden and may be prognostic for survival for metastatic breast cancer patients.

Primary hyperparathyroidism has been associated with increased incidence of morbidity and mortality of the cardiovascular system. The etiopathogenetic mechanisms underlying this association are still not completely clear. Accumulating evidence suggested that a disintegrin and metalloproteinase with thrombospondin-like motifs (ADAMTS) has a role in the development of inflammation and atherosclerosis. In this study, we aimed to determine whether there is a change in serum levels of ADAMTS1, ADAMTS4, carotid intima-media thickness, and cardiovascular risk score after the surgery and also whether there is a relationship between ADAMTS levels and cardiovascular risk score in hypercalcemic primary hyperparathyroidism patients. The study included the 48 consecutive newly diagnosed patients with primary hyperparathyroidism. The patients were evaluated before and six months after parathyroidectomy. The Framingham score is used to calculate cardiovascular risk. Serum ADAMTS levels were determined by a human enzyme-linked immunoassay in all subjects. The fasting glucose, fasting insulin levels and HOMA values were decreased significantly in all patients after surgery compared to the pretreatment values (p hyperparathyroidism compared to the preoperative values (p  0.05). There were statistically significant relationship between cardiovascular risk score and waist/hip ratio, calcium, LDL-cholesterol, carotid intima-media thickness, ADAMTS4 values. Based on the results of the present study, fasting glucose, fasting insulin levels, ADAMTS1, ADAMTS4, and carotid intima-media thickness might be an additional parameters during the management of patients with primary hyperparathyroidism, since these factors might improve after surgery.

Objective: To explore the clinical value of determination of serum PRL levels inpost-menopausal women. Methods: Serum PRL levels were determined with RIA in 596 post-menopausal women (age 45-59, mean 55). Results: The normal range of serum PRL level in this laboratory was 0-30 ng/ml. Among the 596 women tested, 77(13%) had their PRL levels above 30 ng/ml. Further investigation with CT and/or MRI revealed presence of micro-pituitary-adenoma in 31 of the Symptoms of menopausal syndrome and osteoporosis were much more severe in women with hyperprolactinemia then in those without. Conclusion: As hyperprolactinemia might be a high risk factor for development of breast cancer, hormone replacement therapy (HRT) in menopausal women with hyperprolactinemia should be applied very cautiously, even withheld at all. Determination of serum prolactin levels in post-menopausal women is of practical clinical value. (authors)

2004-01-01

Objective: To study the changes of serum leptin, insulin and adiponectin levels and their relationship with BMI in females with simple obesity. Methods: Serum leptin, adiponectin and insulin levels were measured with RIA in 48 pre-obese females (BMI=23-24.9 kg/m 2 ), 40 females with simple obesity, (BMI≥25 kg/m 2 ) and 42 female controls (BMI 18-22.9 kg/m 2 ). Correlations among these variables were studied. Results: Serum leptin, insulin levels were significantly higher and serum adiponectin levels were significantly lower in both the pre-obese and obese females than those in controls. Serum leptin, insulin levels were positively correlated to BMI; Serum adiponectin levels were negatively correlated to BMI. Conclusion: Within normal range of BMI, the leptin-insulin feedback mechanism provided satisfactory self-regulation. However, with excessive BMI, this dynamic equilibrium would be disrupted. The defective equilibrium, together with the abnormal low adiponectin level, would predispose to the development of diabetes mellitus. (authors)

Objective: To measure the serum leptin concentration in simple obese children together with other four kinds of related hormones. Methods: Serum Leptin, Ins, T 3 , T 4 and GH levels were measured by radioimmunoassay in thirty-eight obese children and thirty healthy controls. Results: The levels of serum leptin, Ins and T 3 in obese group were dramatically higher than those in control group (all P 4 concentration between simple obese children and control group (P > 0.05), Serum GH levels was significantly decreased in simple obese children (P < 0.01). There was a positive correlation between serum leptin levels and lns levels (r = 0.46, P < 0.01). Conclusion: In simple obese children there were leptin resistance and endocrine metabolic disturbances, the later might be correlated with the increasing of serum leptin levels; It is suggested that Leptin resistance might play a key role in the development of obesity

To the best of our knowledge, no previous study regarding the serum telomerase levels in Maras powder users (MPUs) has been founded. The aim of the current study was to investigate serum telomerase levels in smokers and MPUs. The study was carried out with 98 patients (36 MPUs, 32 smokers and 30 non-smokers). Blood samples were collected, and after having measured the serum telomerase and malondialdehyde (MDA) levels of the patients, comparison were made between the groups. It has been observed that the serum telomerase and MDA levels of smokers (pnon-smoker control subjects. In addition, the levels of serum telomerase and MDA were observed to be higher in the MPU group compared to those of the smoker group (psmokers. In this context, it may be useful to further measure and assess telomerase activity in such patients in order to better determine the harmful effects associated with these habits.

To study serum leptin level in chronic renal failure (CRF) hemodialysis patients and the relationship between serum leptin level and residue renal function, body composition, and indices of malnutrition, 31 end-stage CRF hemodialysis patients and 38 healthy people were enrolled. Serum leptin levels were detected by radioimmunoassay. BMI, %Fat and LBM were measured by bioelectrical impedance analysis device. Alb, Chol, Hgb, BUN, SCr and Ccr of the patients were also examined. Results showed that Serum leptin level in end-stage CRF hemodialysis patients was markedly higher than that in healthy controls (P 0.05). Conclusion: Hyperleptinemia existed in end-stage CRF hemodialysis patients and might cause the loss of LBM. The leptin level was not correlated with residue renal function, but it could reflect the fat content. However, serum leptin did not play a significant role in protein malnutrition in end-stage CRF hemodialysis patients

Euthyreoid and hyperthyreoid women were subjected to examinations investigating the effect of a dopamine-antagonist (Sulpirid) on serum TSH and prolactin (LTH)-levels. For measurements of serum concentrations the following kits were used: prolactine: CIS; TSH: Ria-mat-TSH (Byk-Mallinkrodt); thyroxine: Tiopac T 4 (Amersham); triiodothyronine: Ria-mat-T 3 (Byk-Mallinkrodt). Sulpirid increased both the LTH and the TSH-levels. In case of hyperthyreosis the effect of Sulpirid on LTH-levels was less pronounced and it had no effect on serum-TSH at all. Pre-treatment with a dopamine-agonist (Bromocryptin) impeded the effect of Sulpirid. It is concluded that dopamine-receptors do have a role in the regulation of TSH-secretion in the hypophysis.

PLAC1 as a serum biomarker for breast cancer.

Directory of Open Access Journals (Sweden)

Hongyan Yuan

Full Text Available Placental-specific protein 1 (PLAC1 is an X-linked trophoblast gene that is re-expressed in several malignancies, including breast cancer, and is therefore a potential biomarker to follow disease onset and progression. Sera from 117 preoperative/pretreatment breast cancer patients and 51 control subjects, including those with fibrocystic disease, were analyzed for the presence of PLAC1 protein as well as its expression by IHC in tumor biopsies in a subset of subjects. Serum PLAC1 levels exceeded the mean plus one standard deviation (mean+SD of the level in control subjects in 67% of subjects with ductal carcinoma in situ (DCIS, 67% with HER2+ tumors, 73% with triple-negative cancer and 73% with ER+/PR+ tumors. Greater sensitivity was achieved using the mean+2 SD of control PLAC1 serum values, where the false positive rate was 3% and was exceeded by 38%, 40%, 60% and 43% of subjects with DCIS, HER2+, TNBC and ER+/PR+/HER2- tumors. PLAC1 was detected in 97% of tumor biopsies, but did not correlate quantitatively with serum levels. There was no significant correlation of serum PLAC1 levels with race, age at diagnosis, body mass index (BMI or the presence of metastatic disease. It remains to be determined whether PLAC1 serum levels can serve as a diagnostic biomarker for the presence or recurrence of disease post-surgery and/or therapy.

We wanted to evaluate the diagnostic value of serum CA-125 concentration, when used in combination with the preoperative contrast-enhanced CT results, to differentiate borderline ovarian tumors (BOTs) from stage I malignant epithelial ovarian tumors (MEOTs). Ninety-eight masses (46 BOTs and 52 stage I MEOTs) from 87 consecutive patients (49 with BOTs and 38 with stage I MEOTs) who had undergone preoperative contrast-enhanced computed tomography (CT) and surgical staging were evaluated retrospectively and independently by two radiologists. The preoperative serum CA-125 concentration was measured in all patients. The utility of analyzing serum CA-125 concentration in combination with the CT results was evaluated by receiver operating characteristic (ROC) curve analysis. An irregular tumor surface and lymphadenopathy were predictive of a MEOT. ROC analysis showed that the combination of CT data and the serum CA-125 level resulted in a higher diagnostic performance than did using the CT alone for differentiating BOTs from MEOTs. The areas under the curves (AUCs) without and with the use of the serum CA-125 level data were 0.67 (95% confidence interval [CI]: 0.57-0.77) and 0.78 (95% CI: 0.68-0.85), respectively, for reader 1 (p = 0.029) and 0.71 (95% CI: 0.61-0.80) and 0.81 (95% CI: 0.72-0.89), respectively, for reader 2 (p = 0.009). The serum CA-125 concentration is of additional diagnostic value when used in conjunction with the CT imaging results for differentiating BOTs from MEOTs.

Full Text Available Background. Alzheimer's disease (AD is the most common cause of dementia in the elderly. AD is characterized by the accumulation of amyloid plaques and neurofibrillary tangles and by massive neuronal loss in the brain. There is epidemiologic and pathologic evidence that AD is associated with vascular risk factors and vascular diseases, contributing to cerebral hypoperfusion with consecutive stimulation of angiogenesis and upregulation of proangiogenic factors such as Angiopoietin-1 (Ang-1. Methods. In the present study, we measured Ang-1 serum levels in 42 patients with AD, 20 patients with mild cognitive impairment (MCI, and in 40 healthy elderly controls by ELISA. Results. We found significantly increased Ang-1 serum levels in patients with AD compared to control subjects (P=0.003. There was no significant difference between MCI patients and healthy controls (P=0.553 or between AD and MCI patients (P=0.054. The degree of cognitive impairment as measured by the mini-mental status examination (MMSE score was significantly correlated with the Ang-1 serum levels in all patients and healthy controls. Conclusions. We found significantly increased Ang-1 serum levels in AD patients. We could also show an association between Ang-1 serum levels and the cognitive status in all patients and healthy controls. Thus, serum Ang-1 could be a potential candidate for a biomarker panel for AD diagnosis.

Nidogen-2 (NID2), a secretory basement membrane protein, has been implicated as a potential biomarker in ovarian cancer and hepatocellular carcinoma. In this study, we aimed to investigate the utility of detecting serum NID2 levels for identification of esophageal squamous cell carcinoma (ESCC) patients and prediction of poor survival outcome. Using an in-house NID2 enzyme-linked immunosorbent assay (ELISA), serum samples from 101 ESCC patients and 50 healthy controls were screened for their NID2 levels. The serum NID2 levels in ESCC patients (median 24.4 μg/L) are significantly higher (p= 4.3e-09) than that of the healthy controls (median 15.85 μg/L). The receiver operating characteristic (ROC) curve demonstrated an area under the curve of 0.756. At the threshold of 17.95 μg/L, the sensitivity and specificity achieved are 0.76 and 0.63, respectively. Kaplan-Meier survival analysis revealed that patients with high serum NID2 levels (⩾ 32.6 μg/L) have significantly higher risk of death (HR = 1.984, 95% CI: 1.175-3.349; log-rank p-value = 0.012) compared to those with low serum NID2 levels (levels has potential diagnostic and prognostic value for ESCC patients.

Full Text Available Abstract Background S100B protein is a potential biomarker of central nervous system insult. This study quantitatively compared two methods for assessing serum concentration of S100B. Methods A prospective, observational study performed in a single tertiary medical center. Included were fifty two consecutive adult patients undergoing surgery for meningioma that provided blood samples for determination of S100B concentrations. Eighty samples (40 pre-operative and 40 postoperative were randomly selected for batch testing. Each sample was divided into two aliquots. These were analyzed by ELISA (Sangtec and a commercial kit (Roche Elecsys® for S100B concentrations. Statistical analysis included regression modelling and Bland-Altman analysis. Results A parsimonious linear model best described the prediction of commercial kit values by those determined by ELISA (y = 0.045 + 0.277*x, x = ELISA value, R2 = 0.732. ELISA measurements tended to be higher than commercial kit measurements. This discrepancy increased linearly with increasing S100B concentrations. At concentrations above 0.7 μg/L the paired measurements were consistently outside the limits of agreement in the Bland-Altman display. Similar to other studies that used alternative measurement methods, sex and age related differences in serum S100B levels were not detected using the Elecsys® (p = 0.643 and 0.728 respectively. Conclusion Although a generally linear relationship exists between serum S100B concentrations measured by ELISA and a commercially available kit, ELISA values tended to be higher than commercial kit measurements particularly at concentrations over 0.7 μg/L, which are suggestive of brain injury. International standardization of commercial kits is required before the predictive validity of S100B for brain damage can be effectively assessed in clinical practice.

Full Text Available The high recurrence rate remains a major problem that strongly influenced the prognosis of hepatocellular carcinoma (HCC patients who received hepatectomy. The presence of microvascular invasion (MVI is regarded as the most important risk factor that contributes to the postoperative recurrence. Our previous study has hinted that serum microRNA-125b (miR-125b was associated with MVI. The aim of the present study was to identify whether serum miR-125b can serve as a biomarker to reliably predict microvascular invasion (MVI preoperatively. MiR-125b was quantified in 108 HCC patients’ serum before they received surgery by quantitative real-time PCR (qRT-PCR. Our results revealed that MVI was associated with relapse free survival (RFS of postoperative HCC patients; surgical margin width was associated with postoperative RFS in MVI present patients, but not in the patients without MVI. Multivariate analysis revealed that miR-125b, tumor size and AFP were the independent predictive factors associated with MVI in this cohort (P = .001, .001, .003, respectively. The probability of the predictive accuracy of miR-125b was 76.95% (51.32% specificity and 87.50% sensitivity, which was almost equal to the classifier established by combination of AFP and tumor size (78.82% probability, 65.63% specificity and 84.21% sensitivity. Furthermore, the combination of tumor size, AFP and miR-125b yielded a ROC curve area of 86.68% (72.37% specificity and 84.38% sensitivity. Our study indicated that serum miR-125b can be used to predict MVI of HCC patients before they received hepatic resection. Therefore, miR-125b can potentially guide individualized treatment, which helps HCC patients, with or without MVI, to benefit from different surgical approach.

Full Text Available Adipose tissue produces a wide range of proteins that may influence the immune system. In this study, we assessed the serum levels of leptin, adiponectin, and ghrelin, in association with the measurements of body composition, in 15 female patients with various autoimmune diseases (systemic lupus erythematosus, primary Sjögren's syndrome, sarcoidosis, mixed connective tissue disease, vasculitis, CREST syndrome, and polymyositis and in 15 healthy female controls. There were no statistically significant differences between the patients and controls with regard to serum leptin, serum ghrelin, global fat mass, adiposity, and fat mass in the android or gynoid regions, whereas serum adiponectin levels were higher in patients than controls (16.3±1.6 μg/mL versus 9.7±0.6 μg/mL; =.01. As adiponectin is known to exhibit potent anti-inflammatory properties, a high adiponectinemia in patients with systemic autoimmune disease may mitigate the inflammatory response. However, the precise consequences of these elevated serum adiponectin levels on the metabolic syndrome development and atherosclerotic cardiovascular risk in this patient population still needs to be determined.

The diagnosis of borderline hyperthyroidism is difficult. A sensitive radioimmunoassay capable of detecting subnormal levels of serum TSH may be of value in confirming this diagnosis because of the suppressed pituitary function in this disease state. This sensitive assay may also be useful in monitoring the suppression of pituitary function in thyroid cancer patients receiving thyroid hormone therapy. A sensitive radioimmunoassay capable of detecting serum TSH levels as low as 0.25 μU/m1 with coefficients of variation less than 17.2% was used to measure serum TSH levels in 80 healthy subjects, 44 hyperthyroid patients, and 25 athyrotic thyroid cancer patients on daily suppressive doses of thyroxine. All healthy subjects had detectable TSH levels with a mean value of 1.17 and two standard deviation ranges of 0.41 - 2.70 μU/m1 (lognormal distribution). Although the mean +-1 SEM value of 0.63 +- 0.003 μUm1 for hyperthyroid patients and 0.76 +- 0.08 μU/ml for thyroid cancer patients were significantly lower than that of healthy subjects (t-test, p<0.05), subnormal levels of serum TSH were found in only 28.6% (12/42) and 24% (6/25) of hyperthyroid and thyroid cancer patients, respectively. TSH stimulation tests performed in 6 of the cancer patients all gave suppressed responses. Because of considerable overlap, serum TSH levels alone cannot distinguish hyperthyroidsm from euthyroidism. However, a sensitive TSH radioimmunoassay such as the one described here may be of value in evaluating the extent of pituitary suppression in thyroid cancer therapy

Aim of the study was to asses and compare serum anti-Mullerian harmone (AMH) levels after laparoscopic ovarian drilling (LOD) and transvaginal hydrolaparoscopy (THL) ovarian drilling in clomifene citrate (CC)-resistant polycystic ovary syndrome (PCOS) patients; secondary outcome was to evaluate postoperative pain to estimate the acceptability of procedures. A total of 246 patients with CC-resistant PCOS were randomized into two groups: 123 underwent LOD and 123 underwent THL ovarian drilling. AMH serum levels were evaluated before and after the procedure; moreover, women were asked to rate pain on a visual analog scale (VAS) from 0 (no pain, perfectly acceptable) to 10 (unbearable pain, completely unacceptable). In both groups, postoperative serum AMH levels were significantly reduced compared to preoperative levels (6.06 ± 1.18 and 5.84 ± 1.16 versus 5.00 ± 1.29 and 4.83 ± 1.10; p ovarian drilling in comparison to THL (3.26 ± 1.1 versus 1.11 ± 0.5; p ovarian drilling is comparable to the LOD in terms of reduction in AMH, but it is preferred by patients in terms of acceptability. These results could support to use of THL ovarian drilling in the treatment of patients with CC- resistant PCOS.

Full Text Available Purpose: We investigated the correlations of serum total testosterone (TT levels with body composition and physical fitness parameters in patients with erectile dysfunction (ED to know the best exercise for testosterone deficiency. Materials and Methods: Eighty-seven ED patients underwent serum TT assessment as well as body composition and basic exercise testing. The bioelectrical impedance analysis was used to assess body composition. Seven types of basic exercise tests were used to determine physical fitness. Correlations between serum TT levels and body composition/physical function parameters were evaluated using partial correlation analyses. A serum TT cut-off value was obtained for the parameters significantly correlated with serum TT levels. Results: The subjects had a mean serum TT level of 342.1 ng/dL. Among the body composition parameters, body and abdominal fat percentages showed statistically significant negative correlations with serum TT levels. Among the basic exercise test parameters, only the cycle ergometer test for cardiorespiratory fitness showed a statistically significant positive correlation with serum TT levels. Conclusions: Serum TT levels in patients with ED, may be increased by reducing fat percentage and improving cardiorespiratory fitness via aerobic exercise.

The present study was conducted to evaluate the serum triglycerides, serum cholesterol, total protein, and IgG levels in elderly patients who were affected by periodontal disease. This study was conducted at the Rajah Muthiah Dental College and Hospital in the periodontics division. The study was conducted for a period of 3 months. This study is a prospective analytical study. Sixty individuals who were systemically healthy in the age group of 50 and above were included in this study. Control and experimental groups of 30 participants each were included. Plaque index, gingival index, probing pocket depth, and clinical attachment loss were recorded. Biochemical parameters such as serum cholesterol, serum triglycerides, total protein, and IgG levels were also evaluated and correlated with the periodontal parameters. Data was analyzed using SPSS version 16.0 (IBM Corp., Armonk, NY). The relationship between periodontal status and the biochemical parameters such as serum cholesterol, serum triglycerides, total protein, and IgG levels were evaluated by Student's t-test. There was no significant difference in the plaque and gingival scores between the experimental and control group. It was observed that serum cholesterol level and total protein level was lower in participants suffering from chronic periodontitis. Triglycerides level was significantly elevated in the experimental group. IgG, a level which is not significant, concluded that there is no difference in control and experimental group. It was concluded from the results obtained from the study that there is an association between serum triglycerides, serum cholesterol, total protein, and periodontal disease. However, further longitudinal and well-controlled studies are required to evaluate the relationship between these biochemical parameters and periodontal disease.

The aim of this study was to assess zinc levels in tinnitus patients, and to evaluate the effects of zinc deficiency on tinnitus and hearing loss. One-hundred patients, who presented to an outpatient clinic with tinnitus between June 2009 and 2014, were included in the study. Patients were divided into three groups according to age: Group I (patients between 18 and 30years of age); Group II (patients between 31 and 60years of age); and Group III (patients between 61 and 78years of age). Following a complete ear, nose and throat examination, serum zinc levels were measured and the severity of tinnitus was quantified using the Tinnitus Severity Index Questionnaire (TSIQ). Patients were subsequently asked to provide a subjective judgment regarding the loudness of their tinnitus. The hearing status of patients was evaluated by audiometry and high-frequency audiometry. An average hearing sensitivity was calculated as the mean value of hearing thresholds between 250 and 20,000Hz. Serum zinc levels between 70 and 120μg/dl were considered normal. The severity and loudness of tinnitus, and the hearing thresholds of the normal zinc level and zinc-deficient groups, were compared. Twelve of 100 (12%) patients exhibited low zinc levels. The mean age of the zinc-deficient group was 65.41±12.77years. Serum zinc levels were significantly lower in group III (p<0.01). The severity and loudness of tinnitus were greater in zinc-deficient patients (p=0.011 and p=0.015, respectively). Moreover, the mean thresholds of air conduction were significantly higher in zinc-deficient patients (p=0.000). We observed that zinc levels decrease as age increases. In addition, there was a significant correlation between zinc level and the severity and loudness of tinnitus. Zinc deficiency was also associated with impairments in hearing thresholds.

Recent studies suggest that high levels of serum uric acid of very early life are a result of the in-utero environment and may lead to elevated blood pressure (BP) in adulthood. However, serum uric acid levels can change throughout life. We investigated the effect of serum uric acid levels in childhood on the BP tracking and analysed BP according to changes in serum uric acid levels in early life. A total of 449 children from the Ewha Birth and Growth Cohort study underwent at least 2 follow-up examinations. Data were collected across 3 check-up cycles. Serum uric acid levels, BP, and anthropometric characteristics were assessed at 3, 5, and 7 years of age. Children with a serum uric acid level higher than the median values had significantly increased systolic BP (SBP) and diastolic BP at 3 years of age. Baseline serum uric acid levels measured at 3 years of age, significantly affected subsequent BP in the sex and body mass index adjusted longitudinal data analysis (P uric acid over time, subjects with high uric acid levels at both 3 and 5 years of age had the highest SBP at 7 years of age. These findings suggest the importance of maintaining an adequate level of serum uric acids from the early life. Appropriate monitoring and intervention of uric acid levels in a high-risk group can reduce the risk of a future increased BP. © American Journal of Hypertension, Ltd 2017. All rights reserved.

The aim of this study was to assess the preoperative nutritional status of patients undergoing thoracic surgery using different nutritional tools. . We conducted a prospective study on a sample of 43 thoracic patients, including 23 with neoplasms and 20 with non-neoplastic pathology who underwent thoracic surgery procedures between July-September 2011, in the Thoracic Surgery Clinic in Iaşi. Weight and height were measured and body mass index (BMI) was calculated. WHO classification for BMI categories was used. Preoperative serum level of transthyretin (TTR) and demographic data (gender, age) were also assessed. All patients were examined by the Subjective Global Assessment (SGA) and the Nutritional Risk Screening 2002 (NRS 2002). After performing SGA, 67.9% of the patients were well-nourished, 21.4% were moderately or suspected of being malnourished and 10.7% were severely malnourished. The level of TTR was significantly lower in the moderately or severely malnourished group, compared to those considered well-nourished. According to NRS-2002, 42.9% of the patients were considered at nutritional risk. The level of TTR of these patients was lower than the level of TTR of the patients without nutritional risk, but without statistical significance. Subjective Global Assessment (SGA) and the Nutritional Risk Screening 2002 (NRS 2002) are useful in identifying patients with nutritional risk, so that appropriate nutritional management could be initialised even before surgery.

Objective: To determine the serum 25-hydroxycalciferol levels [25(OH)D] in adults with pre-diabetes and normoglycaemia to examine a possible association of vitamin D deficiency with pre-diabetes. Study Design: Case control study. Place and Duration of Study: Armed Forces Institute of Pathology, Rawalpindi, from November 2012 to July 2013. Methodology: A total of 272 adults including 136 pre-diabetics and 136 normoglycaemics of either gender aged 20 years and above were consecutively inducted. Patients with diabetes mellitus, pregnancy, rickets and osteomalacia, ischemic heart disease, chronic kidney disease and chronic liver disease were excluded. Fasting Plasma Glucose (FPG) was estimated with hexokinase method on Modular p800 Roche chemistry analyzer while serum 25(OH)D was measured on Diasorin Liaison immunoassay analyzer using the chemiluminescent technique. Mean 25(OH)D levels in pre-diabetic and normoglycaemic groups were compared using Mann-Whitney U test. Spearman's correlation coefficient 'rs' was determined between serum 25(OH)D and FPG. Odds ratio for vitamin D deficiency was also calculated. Results: Mean serum 25(OH)D level was low in pre-diabetics (23.2 nmol/L) as compared to normoglycaemics (29 nmol/L; p=0.001). Serum 25(OH)D level had inverse correlation with FPG (rs = -0.448, p=0.000). There was also significant association of vitamin D deficiency with pre-diabetes compared with normoglycaemia (OR: 2.21, p= 0.016; 95 percentage CI: 1.15-4.27). Conclusion: Vitamin D deficiency with pre-diabetes suggested that vitamin D may have an important role in pathogenesis of pre-diabetes. (author)

Full Text Available Objectives: Intracerebral hemorrhage (ICH is one of the most mortal subtypes of stroke. Due to the angiogenic, neurotropic, and vessel-dilating properties of basic fibroblast growth factor (bFGF in the brain, role of bFGF has been investigated in a number of neurological disorders. So far, there is only study about serum bFGF levels in patients with ICH. The first aim of the present research is to investigate whether increased serum bFGF in patients with ICH. Also, second aim was to study the association between serum levels of bFGF and clinical status in patients with ICH.Materials and methods: We measured the serum levels of bFGF in 30 patients with ICH during acute period. Age and sex matched healthy subjects (n=30 were included in controls. Serum bFGF levels were measured using an enzyme-linked immunosorbent assay method.Results: The patients with intracerebral hemorrhage had higher serum levels of bFGF when compared with the healthy controls (12.89±3.23 ng/ml, 5.28±1.75 ng/ml; p=0.001. No statistically significant difference was determined between bFGF levels of the patients who died as compared to the patients who lived (13.49±4.13 ng/ml; 12.43±3.43 ng/ml, p>0.05. No statistically significant difference was found between bFGF levels of the patients with intraventricular hemorrhage as compared to the patients without intraventricular hemorrhage (13.54±3.92 ng/ml; 12.24±2.29 ng/ml, p>0.05. There was no correlation between serum bFGF, hematoma volume, Gloskow coma scale, and National Institutes of Health stroke scale (p>0.05.Conclusion: The increased bFGF level may be one of the mechanisms that lead to angiogenesis and neuroprotection after ICH in human. .

measured by immunoassay, and potential determinants of the serum sortilin level were assessed by generalized linear models. Serum levels of brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor (VEGF) were measured in previous studies. We identified a significant increase of serum...... sortilin levels in depressed individuals compared with controls (P = 0.0002) and significant positive correlation between serum sortilin levels and the corresponding levels of BDNF and VEGF. None of the genotyped SNPs were associated with depression. Additional analyses showed that the serum sortilin level...... was influenced by several other factors. Alcohol intake and body mass index, as well as depression, serum BDNF and serum VEGF were identified as predictors of serum sortilin levels in our final multivariate model. In conclusion, the results suggest a role of circulating sortilin in depression which may relate...

Full Text Available The role of inflammation being minimal in the pathogenesis of type 2 diabetes mellitus (T2DM in nonobese patients; the aim of the study was to investigate the role of adenosine deaminase (ADA and see its association with diabetes mellitus. The preliminary case control study comprised of 56 cases and 45 healthy controls which were age and sex matched. 3 mL venous blood samples were obtained from the patients as well as controls after 8–10 hours of fasting. Serum ADA and routine biochemical parameters were analyzed. Serum ADA level was found significantly higher among nonobese T2DM subjects with respect to controls (38.77±14.29 versus 17.02±5.74 U/L; P<0.0001. Serum ADA level showed a significant positive correlation with fasting plasma glucose (r=0.657; P<0.0001 level among nonobese T2DM subjects, but no significant correlation was observed in controls (r=-0.203; P=0.180. However, no correlation was observed between serum ADA level compared to BMI and HbA1c levels. Our study shows higher serum ADA, triglycerides (TG and fasting plasma glucose (FPG levels in nonobese T2DM patients, and a strong correlation between ADA and FPG which suggests an association between ADA and nonobese T2DM subjects.

Full Text Available The preoperative management of hilar cholangiocarcinoma (HC with jaundice focuses on decreasing the total serum bilirubin level (SBL by performing preoperative biliary drainage (PBD. However, it takes about 6-8 weeks for the SBL to fall at a sufficient extent. The objective of this preliminary study was to evaluate the impact of Molecular Adsorbent Recirculating System (MARS® dialysis (in association with PBD on SBL decrease. From January 2010 to January 2011, we prospectively selected all jaundiced patients admitted to our university hospital for resectable HC and requiring PBD prior to major hepatectomy. The PBD was followed by 3 sessions of MARS dialysis over a period of 72 h. A total of 10 patients with HC were screened and two of them were included (Bismuth-Corlette stage IIIa, gender ratio 1, median age 68 years. The initial SBL in the two patients was 328 and 242 μmol/l, respectively. After three MARS dialysis sessions, the SBL had fallen by 30 and 52%, respectively. After the end of each session, there was a SBL rebound of about 10 μmol/l. The MARS decreased the serum creatinine level, the platelet count and the prothrombin index, but did not modify the serum albumin level. Pruritus disappeared after one and two sessions, respectively. MARS-related morbidity included hypotension (n = 1, tachycardia (n = 1, thrombocytopenia (n = 2 and anaemia (n = 1. When combined with PBD, MARS dialysis appears to accelerate the decrease in SBL and thus may enable earlier surgery. This hypothesis must be validated in a larger study.

Androgens and insulin may contribute to increased sebum production in the pathogenesis of acne vulgaris. We investigated the association between serum desnutrin levels and acne vulgaris in the pathogenesis of insulin resistance. 25 patients presenting with acne vulgaris and 25 control subjects participated in this study. Fasting blood glucose, triglycerides, LDL, VLDL, HDL, total cholesterol, insulin, C-peptide and thyroid function tests were measured. The homeostasis model assessment of insulin resistance (HOMA-IR) was used to calculate insulin resistance. Desnutrin levels were determined by enzyme-linked immunosorbent assay (ELISA) according to the manufacturer's protocol. Patients with acne vulgaris had a mean serum desnutrin level of (8.83 ± 1.13 μIU/mL), which was statistically significantly lower in the control group (10:58 ± 3.43 μIU/mL). In patients with acne vulgaris the serum glucose levels, insulin levels and HOMA-IR values (87.92 ± 7:46 mg/dL, 11.33 ± 5.93 μIU/mL, 2.49 ± 1.40, respectively) were significantly higher than the control group (77.36 ± 9.83 mg/dL, 5.82 ± 2.68 μIU/mL, 1.11 ± 0.51, respectively) (p = 0.01, pacne vulgaris, as a result of increased levels of serum glucose and insulin, the function of desnutrin was suppressed, perhaps contributing to insulin resistance.

Serum amylase and lipase activities and creatinine concentration were determined before surgery, and at 1 and 2 days after exploratory laparotomy in 24 dogs. Examination of all viscera was done during each laparotomy, but a surgical procedure was not performed. The mean serum activities for lipase were: before surgery, 0.71 (0.0 to 2.0) Cherry Crandall units (CCU)/L; 1 day after surgery, 2.1 (0.0 to 4.5) CCU/L; and 2 days after surgery, 1.19 (0.0 to 3.9) CCU/L. The mean serum activities for amylase were: before surgery, 1,958 (1,027 to 3,426) IU/L; 1 day after surgery, 1,538 (937 to 2,659) IU/L; and 2 days after surgery, 1,663 (1,066 to 2,274) IU/L. Serum creatinine concentrations before surgery, 1 day after surgery, and 2 days after surgery were 0.88 (0.2 to 1.7) mg/dl, 0.78 (0.4 to 1.3) mg/dl, and 0.78 (0.3 to 1.3) mg/dl, respectively. Mean preoperative, day-1, and day-2 serum amylase activities and serum creatinine concentrations did not differ significantly from each other. Mean preoperative and day-2 serum lipase activities did not differ significantly; however, mean serum lipase activity was significantly greater when day 1 activities were compared with preoperative activities (P = 0.0002). Post-mortem examinations revealed no gross or histologic evidence of pancreatitis in any dog. The results of this study show that a 3 or more fold increase in serum lipase activity may occur after routine exploratory laparotomy in dogs without clinical signs or gross evidence of pancreatitis. Histologic evidence of pancreatitis was not found in the right pancreatic lobes in any dog.

Serum selenium has been implicated as a risk factor for lung cancer, but the issue remains unsettled. We tested in a cohort of 3,333 males aged 53 to 74 years the hypothesis that a low serum selenium would be associated with an increased risk of lung cancer mortality.During 16 years, 167 subjects(5.......1%) died from lung cancer; 48 males (5.0%) among males with low serum selenium, 0.4-1.0 μmol·l(-1), n=965, 57 males (5.1%) among males with medium serum selenium, 1.1-1.2 μmol·l(-1), n=1,141, and 62 males (5.1%) among males with high serum selenium, 1.3-3.0 μmol·l(-1), n=1,227. After adjustment for age...... (chronic bronchitis and peak flow), referencing the lowest level of serum selenium HRs were 1.17(0.79-1.75), and 1.43(0.96-2.14), respectively. Among heavy smokers a high serum selenium was associated with a significantly increased risk of lung cancer mortality after taking into account all potential...

Aim: The present study was conducted to evaluate the serum triglycerides, serum cholesterol, total protein, and IgG levels in elderly patients who were affected by periodontal disease. Materials and Methods: This study was conducted at the Rajah Muthiah Dental College and Hospital in the periodontics division. The study was conducted for a period of 3 months. This study is a prospective analytical study. Sixty individuals who were systemically healthy in the age group of 50 and above were included in this study. Control and experimental groups of 30 participants each were included. Plaque index, gingival index, probing pocket depth, and clinical attachment loss were recorded. Biochemical parameters such as serum cholesterol, serum triglycerides, total protein, and IgG levels were also evaluated and correlated with the periodontal parameters. Data was analyzed using SPSS version 16.0 (IBM Corp., Armonk, NY). The relationship between periodontal status and the biochemical parameters such as serum cholesterol, serum triglycerides, total protein, and IgG levels were evaluated by Student's t-test. Results: There was no significant difference in the plaque and gingival scores between the experimental and control group. It was observed that serum cholesterol level and total protein level was lower in participants suffering from chronic periodontitis. Triglycerides level was significantly elevated in the experimental group. IgG, a level which is not significant, concluded that there is no difference in control and experimental group. Conclusion: It was concluded from the results obtained from the study that there is an association between serum triglycerides, serum cholesterol, total protein, and periodontal disease. However, further longitudinal and well-controlled studies are required to evaluate the relationship between these biochemical parameters and periodontal disease. PMID:28462181

Endocan has been shown to be a marker for several cancers and may show degree of malignancy. The aim of this study is to assess serum levels of endocan before and after surgery on low-grade gliomas (LGGs). Endocan was assayed by commercially available enzyme-linked immunosorbent assay (ELISA) kits in a total of 19 patients and 12 controls. Serial serum samples were obtained before and after surgery (1 st day, 1 st week, and 1 st month of surgery). Control samples were collected from cord blood during cesarean section. The results were compared with control brain tissues. Controls showed significantly lower serum endocan levels compared to before and after surgery ( P < 0.05). There is a trend of increase in mean serum levels from before surgery and during the very early period after surgery (during first week); however, in the first month, mean serum levels became lower. Endocan, a vital molecule for angiogenesis, is highly expressed before and after surgery in LGGs, but long-term data is needed. Furthermore, future studies should include high-grade gliomas to discuss whether endocan is associated with recurrence and response to treatment.

This study investigated plasma carnitine levels in patients undergoing allogenic bone marrow transplantation. The patients received fat-based TPN (50% fat, 50% CHO; calorie: nitrogen ratio 125:1) for an average of 33 +/- 7.5 days. TPN was started before transplantation and stopped when patients were able to eat. Caloric needs were estimated using the Harris-Benedict equation; 150% of the estimated BEE was given for the first two weeks after transplantation. The amount of TPN was gradually decreased as patients resumed their oral intake. All patients had low-normal serum carnitine levels before transplantation. There was no significant change in total or free serum carnitine levels during the course of TPN. However, in patients who had symptoms of graft vs. host reaction (GVH), the highest carnitine values during GVH (total 72.3 +/- 6.5 and free 61.2 +/- 12.4 mumol/l) were significantly higher (p < 0.001) than the baseline values (total 27.1 +/- 9.3 and free 24.9 +/- 9.6 mumol/l) or the highest non GVH values after transplantation (total 32.0 +/- 10.7 and free 29.0 +/- 10.7 mumol/l, respectively). The serum triglyceride, total cholesterol, and HDL cholesterol remained within normal range. In conclusion, bone marrow transplant patients receiving fat-based TPN have normal circulating levels of carnitine. GVH reaction caused an increase in the carnitine levels, which was probably due to increased tissue catabolism.

The serum levels of ferritin in 394 patients, including 339 patients with various malignant tumors and 23 with various non-malignant diseases, and 32 healthy subjects were determined. The normal levels of ferritin were 82.7 +- 42.3 ng/ml for males and 42.0 +- 36.9 ng/ml for females. The positive ratio of serum ferritin level was 28% in patients with malignant tumors and 22% in patients with non-malignant diseases. The usefulness of serum ferritin assay in screening for malignant tumors appeared to be limited. High serum levels of ferritin were found in patients with malignant lymphoma (positive ratio: 42%), pulmonary cancer (38%) and esophageal cancer (37%). According to the histological types, epidermoid cancer appeared to produce a higher serum level of ferritin than adenocarcinoma in patients with pulmonary cancer. It was interesting that malignant lymphoma had a high serum level of ferritin in spite of its low serum level of CEA. Carcinoma of the digestive tracts except for esophagus was considered to have a normal serum ferritin level in spite of the advanced stage. There was no close relationship between serum ferritin levels and CEA levels in patients with pulmonary cancer and breast cancer. Serum CEA assay was more useful for detection of tumors than serum ferritin assay in patients with breast cancer. Serum ferritin levels in patients with good prognosis decreased following radiation therapy, but those in patients with poor prognosis elevated or unchanged in spite of therapy. Therefore, serial ferritin determinations may be useful for evaluation of radiotherapy and assessment of prognosis. (J.P.N.)

The poor correlation between serum and urine glucose measurements has led to the development of new techniques for monitoring the blood glucose level in diabetic patients. Either a nurse or the patient can perform these tests, which involve spreading a single drop of blood onto a reagent strip. A colour change that is proportional to the serum glucose level can be read visually or with a reflectance meter. Evaluated against simultaneous serum glucose levels determined by the hospital biochemi...

Digoxin serum levels were examined in 40 patients using enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay (RIA) and correlated with levels of potassium, magnesium, creatinine, urea, glomerular filtration (GF) and with clinical signs of different degrees of digitalis serum concentration. The digoxin level assessed by ELISA and RIA methods correlated fairly closely. An average dependence was found between digoxin levels and levels of creatinine, urea and GF. A correlation was observed between a high level of digoxin and clinical signs of digitalis intoxication.

Objective: To investigate the changes of maternal serum GH levels during late gestation and soon (24 hours) after delivery. Methods: Serum GH levels were measured with RIA in 6 women during late pregnancy, 32 pre-delivery women, 20 women soon after delivery and 76 controls (normal non-pregnant women). Results: Serum GH levels in the late pregnant (20.1±1.87 μg/L) and pre-delivery (21.07±7.77 μg/L) women were significantly higher those in women soon after delivery (2.76±0.88 μg/L) and controls (2.73±2.15 μg/L) (p<0.01). There was no significant difference between the levels in late pregnant and pre-delivery women, nor between those in the controls and women soon after delivery. Conclusion: Elevation of maternal serum GH levels during pregnancy reflects the normal maternal adaptation to meet the demand for fetal growth. However, the origin of increase is mainly from the placenta (placental GH or HGH-V) rather than from the pituitary (HGH-N); hence the rapid decline soon after delivery

A third of the population are estimated to have NAFLD of varying severity. Serum immunoglobulins are frequently elevated in patients with chronic liver disease, but little is known about serum immunoglobulin levels in patients with NAFLD. Aim of this study was to evaluate serum immunoglobulin levels (IgA, IgG, and IgM) in a large cohort of patients with biopsy-proven NAFLD and determine if immunoglobulin levels are associated with clinical or histological features. Patients seen in a tertiary fatty liver clinic between 1999 and 2009 were included. Liver biopsies were assessed using the Kleiner score. Immunoglobulin levels and other blood tests were taken at time of biopsy. 285 patients (110 simple steatosis and 175 NASH) had serum immunoglobulins measured within 6months of liver biopsy. 130 (46%) patients had elevated (>1× upper limit of normal) serum IgA levels, 28 (10%) patients had elevated IgG and 22 (8%) raised IgM. Serum IgA levels were elevated more frequently in patients with NASH compared with subjects with simple steatosis (55% vs. 31%, pliver fibrosis (Kleiner stage 3-4). There was a significant positive association between serum IgA levels and the stage of fibrosis (pfibrosis following multivariate analysis. A model constructed from these independent predictors accurately predicted advanced fibrosis (AUROC 0.87). The serum IgA level was frequently elevated in patients with NAFLD and was an independent predictor of advanced fibrosis. Copyright © 2014 European Association for the Study of the Liver.

The tumor marker CA-125 is an embrional glycoprotein detectable in tissues derived from celomatic epitelium. Serum Ca-125 was determined by RIA in 66 patients with various ovarian pathologies (16 malignant at stage III-IV and 50 benign). Six patients with ovarian carcinoma were monitored during the first week after surgery and chemiotherapy for a total of 150 days of treatment. It has been observed that CA-125 serum level is consistently above the normal range (>35 U/ml) in all malignant diseases. In benign pathology, levels above the normal were found to be represented almost exclusively by ovarian endometriosis. Furthermore, the results demonstrate that chemiotherapy alone is capable of lowering CA-125 serum levels. This tumor marker may be of great advantage in diagnosis and follow-up of ovarian malignancy

Background Exposure to pesticides has been reported to increase the risk of Parkinson disease (PD), but identification of the specific pesticides is lacking. Three studies have found elevated levels of organochlorine pesticides in postmortem PD brains. Objective To determine whether elevated levels of organochlorine pesticides are present in the serum of patients with PD. Design Case-control study. Setting An academic medical center. Participants Fifty patients with PD, 43 controls, and 20 patients with Alzheimer disease. Main Outcome Measures Levels of 16 organochlorine pesticides in serum samples. Results β-Hexachlorocyclohexane (β-HCH) was more often detectable in patients with PD (76%) compared with controls (40%) and patients with Alzheimer disease (30%). The median level of β-HCH was higher in patients with PD compared with controls and patients with Alzheimer disease. There were no marked differences in detection between controls and patients with PD concerning any of the other 15 organochlorine pesticides. Finally, we observed a significant odds ratio for the presence of β-HCH in serum to predict a diagnosis of PD vs control (odds ratio, 4.39; 95% confidence interval, 1.67–11.6) and PD vs Alzheimer disease (odds ratio, 5.20), which provides further evidence for the apparent association between serum β-HCH and PD. Conclusions These data suggest that β-HCH is associated with a diagnosis of PD. Further research is warranted regarding the potential role of β-HCH as a etiologic agent for some cases of PD.

Matrix metalloproteinase 11 (MMP11) has been shown to play a key role in human tumor progression and indicates poor clinical outcome in cancer patients. The current study aimed to evaluate the relationship between serum levels of MMP-11 and prognosis in colon cancer patients. Serum levels of MMP-11 were determined in 92 colon cancer patients and 92 healthy individuals using an enzyme-linked immunosorbent assay (ELISA). Associations between serum MMP-11 levels and clinicopathological characteristics of the patients and their outcomes were investigated. Survival analyses were performed to measure the 5-year overall survival (OS) and disease-free survival (DFS). Serum MMP-11 levels were substantially higher in colon cancer patients than in healthy controls. Moreover, serum MMP-11 levels were significantly higher in patients with advanced T status, lymph node metastasis, distant metastasis, and a higher TNM stage. Elevated serum levels of MMP-11 were identified as an independent prognostic factor for 5-year mortality and adverse events associated with colon cancer. Multivariate Cox regression analysis identified the serum MMP-11 level as an independent predictor of OS and DFS. Our study established that high serum levels of MMP-11 are associated with poor clinical outcome and may serve as a prognostic biomarker in colon cancer patients.

Paul, R.F.; Hassan, M.; Nazar, H.S.

2012-01-01

Background: Leptin is product of ob gene, an adipose tissue derived hormone that plays a key role in the regulation of body fat mass by regulating appetite and metabolism while balancing energy intake and energy expenditure. The objective of the study was to evaluate possible association between serum leptin levels and Body Mass Index (BMI) of gender in adult age group. Methods: Two-hundred-seventy subjects aged 20-50 years were randomly selected from general population of Abbottabad. The subjects were grouped on the basis on BMI (89 normal, 92 overweight, and 89 obese). After complete evaluation, demographic data was recorded and BMI. Non-fasting venous blood samples were drawn to measure serum leptin and serum glucose levels. The data were analysed using SPSS-15 calculating mean, percentage, independent t-test and chi-square test. Correlation and regression curve analysis were obtained, and p and r values were calculated. Results: Serum leptin levels and differences between genders were significant in all body mass indices. For normal BMI group the mean values for leptin were 2.6+-1.5 gamma g/ml in men, and 17.3+9-10.2 gamma g/ml for women. For Group-2 mean leptin levels in men were 9.9+-6.8 gamma g/ml and in women were 34.8+-13.6 gamma g/ml. For Group-3 BMI comprising obese subjects mean values for men were 21.3+-14.2 gamma g/ml and for women were 48.21+-21.2 gamma g/ml (p<0.001). Conclusion: A progressive increase in serum leptin concentration was observed with an increase in BMI. Significant difference between leptin concentrations in either gender was found in normal, overweight and obese subjects. (author)

Objective: To measure the zinc level in fertile and infertile population and to find out relationship of serum and seminal plasma zinc levels and serum testosterone in oligospermic and azoospermic infertile men. Design: Comparative study. Place and Duration of Study: The Infertility Clinic, Jinnah Postgraduate Medical Center (JPMC), Karachi, from January 2002-July 2003. Patients and Methods: Fifty-eight primary infertile male subjects, without any treatment, who had regular unprotected intercourse for at least 12 months without conception with their partners, aged 20-40 years, having normal and regular menstrual cycles without any uterine pathology or hormonal disturbance were selected from Infertile Clinic, Jinnah Postgraduate Medical Center, Karachi. After semen analyses, they were grouped as, oligospermic (30), and azoospermic (28). Twenty-five known fertile male selected from general population (their spouse had given birth to a child within one year) and after semen analysis were taken as normospermic control group. Semen analyzed according to WHO criteria and serum and seminal plasma zinc was estimated by 5Br. PAPS colorimetric method. Serum testosterone, LH, and FSH were measured by ELISA, using kits supplied by Diagnostic System Laboratories (DSL), U.S.A. Results: The mean value for testosterone was significantly low in oligospermic, (8.04+0.76) and azoospermic subjects (7.14+0.27) as compared to normospermic (9.90+0.14) control groups (p<0.05, p<0.001 respectively), serum LH (p<0.05, p<0.001) respectively) and FSH (p<0.05) were significantly higher than normospermic control group. Serum and seminal plasma zinc levels was low in oligospermic, and azoospermic subjects when compared with normospermic control groups (p<0.05, p<0.001 respectively). This suggests its involvement in spermatogenesis and infertility in such patients. Seminal zinc level has weak correlation with testosterone in oligospermic (r=0.44, p<0.05) and with serum zinc in azoospermic

Full Text Available Introduction: Gestational diabetes mellitus (GDM is defined as any degree of glucose intolerance with onset or first recognition during pregnancy.[1] Pregnancy is a unique situation in which there is a physiological temporary increase in insulin resistance (IR. The mechanisms responsible for the gestational-induced IR are not completely understood. The current study was undertaken to compare adiponectin levels during 24–28 weeks period of gestation in drug-naive newly diagnosed GDM women with a cohort of normoglycemic pregnant women. Subjects and Methods: A total of 47 pregnant women in the age group of 18–40 years were included in this cross-sectional study, of which 13 were GDM cases and 34 were normoglycemic controls.

Resistin is a novel adipocyte-secreted hormone that has been proposed to be the link between obesity and diabetes, although little appears to be known regarding the physiological role of resistin in human beings. We aimed to explore the relationship between serum resistin level and certain anthropometric and metabolic parameters. Seventy-one healthy subjects with a mean body mass index of 23 kg/m 2 or greater were recruited in this study. Anthropometric measurements including height, weight, body mass index, waist and hip circumferences, waist-to-hip ratio, and blood pressure were recorded. Insulin resistance was measured by homeostasis model assessment (HOMA). Fasting serum resistin, insulin and plasma glucose, lipid profiles, and uric acid levels were measured. The results revealed that serum resistin level did not correlate with any markers for adiposity, blood pressure, fasting plasma glucose, or uric acid level for either sex. Serum resistin level correlated negatively with fasting insulin level (gamma=-0.455, P=.006) and HOMA (gamma=-0.455, P=.006) in women but not in men. Serum resistin level only correlated negatively with high-density lipoprotein cholesterol (HDL-C) level in men (gamma=-0.347, P=.038); there was no correlation between serum resistin level and lipid profiles in women. Multiple linear regression analysis using the logarithm of resistin as a dependent variable revealed that only HDL-C level (beta=-.058, P=.019) was an independent significant predictor for resistin in men; however, the analysis revealed that HDL-C level (beta=-.044, P=.029) and HOMA (beta=-.719, P=.004) were independent significant predictors for resistin in women. In conclusion, resistin is not related to adiposity, blood pressure, insulin resistance, fasting plasma glucose level, and most lipid profiles. Resistin correlates negatively with HDL-C level for both sexes. The role of resistin in metabolic syndrome warrants further investigation.

The role of progranulin in individuals with metabolic syndrome is not exactly clear.We aimed to assess the serum level of progranulin in type 2 diabetic patients with and without metabolic syndrome and compare them with healthy controls. The study included 60 patients with type 2 diabetes and 30 healthy individuals as control groups. Biochemical parameters and progranulin levels were determined. Subjects with metabolic syndrome showed significantly higher levels of triglyceride, waist circumference, BMI, systolic and diastolic blood pressure than subjects without metabolic syndrome and the control groups, while HDL-cholesterol level was significantly lower in subjects with metabolic syndrome. Fasting blood sugar was significantly higher in type 2 diabetic patients than in the control groups. Serum level of progranulin was slightly increased in subjects with metabolic syndrome. Serum progranulin level had no significant relationship with metabolic syndrome components. Serum progranulin was also not dependent on cardiometabolic risk factors for subjects with metabolic syndrome, but it could be considered for the management of type 2 diabetes mellitus. Further studies are recommended to explain the effect of progranulin on the pathogenesis of metabolic risk factors.

Several treatment modalities exist for the treatment of perioperative anemia. We determined the effect of oral iron supplementation on preoperative anemia, and the use of blood-conserving interventions before total hip arthroplasty (THA) and total knee arthroplasty (TKA). A total of 3435 total joint arthroplasties (1461 THAs and 1974 TKAs) were analyzed during 2 phases of a blood conservation program. The first phase used erythropoietin alfa (EPO) or intravenous (IV) iron for patients at risk for perioperative anemia. The second phase included these interventions, as well as preoperative iron supplementation. The effect on preoperative hemoglobin (Hb) and serum ferritin, as well as EPO and IV iron utilization, was determined. Oral iron therapy increased preoperative Hb level by 6 g/L (P iron reduced from 4% to 2% (P = .05) and 5% to 2% (P iron therapy reduced the burden of perioperative anemia and reduced utilization of other blood-conserving therapies before THA and TKA. Future research should delineate the cost-effectiveness of oral iron therapy. Copyright © 2017 Elsevier Inc. All rights reserved.

Objective: To investigate the clinical significance of the changes of serum cortisol and insulin levels in neonates with asphyxia. Methods: Serum cortisol levels were determined with CLIA and serum insulin levels with RIA in 38 neonates with asphyxia (mild degree 20, advanced 18) and 30 controls. Results: 1) In mild cases, serum insulin levels were significantly higher than those in controls (p<0.01) and serum cortisol levels were very significantly higher (p<0.001). 2) In advanced cases, both serum insulin and cortisol levels were very significantly higher than those in the controls (p<0.001). Conclusion: Hypoxia in the neonates with asphyxia is a very severe stress and will induce hypersecretion of cortisol and hyperglycemia which is detrimental to the patients. However hypersecretion of insulin will result in hypoglycemia, which is also very damaging. Physicians in charge should be aware of these possibilities and deal with them appropriately

Alterations of serum levels of BDNF-related miRNAs in patients with depression.

You-Jie Li

Full Text Available Depression is a serious and potentially life-threatening mental disorder with unknown etiology. Emerging evidence shows that brain-derived neurotrophic factor (BDNF and microRNAs (miRNAs play critical roles in the etiology of depression. Here this study was aimed to identify and characterize the roles of BDNF and its putative regulatory miRNAs in depression. First, we identified that miR-182 may be a putative miRNA that regulates BDNF levels by bioinformatic studies, and characterized the effects of miR-182 on the BDNF levels using cell-based studies, side by side with miR-132 (a known miRNA that regulates BDNF expression. We showed that treatment of miR-132 and miR-182 respectively decreased the BDNF protein levels in a human neuronal cell model, supporting the regulatory roles of miR-132 and miR-182 on the BDNF expression. Furthermore, we explored the roles of miR-132 and miR-182 on the BDNF levels in depression using human subjects by assessing their serum levels. Compared with the healthy controls, patients with depression showed lower serum BDNF levels (via the enzyme-linked immunosorbent assays and higher serum miR-132 and miR-182 levels (via the real-time PCR. Finally, the Pearson's (or Spearman's correlation coefficient was calculated to study whether there was a relationship among the Self-Rating Depression Scale score, the serum BDNF levels, and serum BDNF-related miRNA levels. Our results revealed that there was a significant negative correlation between the SDS scores and the serum BDNF levels, and a positive correlation between the SDS scores and miR-132 levels. In addition, we found a reverse relationship between the serum BDNF levels and the miR-132/miR-182 levels in depression. Collectively, we provided evidence supporting that miR-182 is a putative BDNF-regulatory miRNA, and suggested that the serum BDNF and its related miRNAs may be utilized as important biomarkers in the diagnosis or as therapeutic targets of depression.

Full Text Available Background/Aims: Hyperuricemia has been reported to affect renal hemodynamics in rat models. We evaluate the relationship between serum uric acid and intrarenal hemodynamic parameters in humans, utilizing the plasma clearance of para-aminohippurate (CPAH and inulin (Cin. Methods: Renal and glomerular hemodynamics were assessed by simultaneous measurement of CPAH and Cin in 58 subjects. Of these, 19 subjects were planned to provide a kidney for transplantation; 26 had diabetes without proteinuria; and 13 had mild proteinuria. Renal and glomerular hemodynamics were calculated using Gomez`s formulae. Results: Cin was more than 60 ml/min/1.73m2 in all subjects. Serum uric acid levels correlated significantly with vascular resistance at the afferent arteriole (Ra (r = 0.354, p = 0.006 but not with that of the efferent arteriole (Re. Serum uric acid levels (β = 0.581, p = a after adjustment for several confounders (R2 = 0.518, p = Conclusions: These findings suggest, for the first time in humans, that higher serum uric acid levels are associated significantly with Ra in subjects with Cin > 60 ml/min/1.73m2. The increase in Ra in subjects with higher uric acid levels may be related to dysfunction of glomerular perfusion.

Full Text Available The Ki-67 labelling index is significant for the management of breast cancer. However, the concordance of Ki-67 expression between preoperative biopsy and postoperative surgical specimens has not been well evaluated. This study aimed to find the correlation in Ki-67 expression between biopsy and surgical specimens and to determine the clinicopathological risk factors associated with discordant values.Ki-67 levels were immunohistochemically measured using paired biopsy and surgical specimens in 310 breast cancer patients between 2008 and 2013. ΔKi-67 was calculated by postoperative Ki-67 minus preoperative levels. The outliers of ΔKi-67 were defined as [lower quartile of ΔKi-67-1.5 × interquartile range (IQR] or (upper quartile + 1.5 × IQR and were evaluated according to clinicopathological parameters by logistic regression analysis.The median preoperative and postoperative Ki-67 levels were 10 (IQR, 15 and 10 (IQR, 25, respectively. Correlation of Ki-67 levels between the two specimens indicated a moderately positive relationship (coefficient = 0.676. Of 310 patients, 44 (14.2% showed outliers of ΔKi-67 (range, ≤-20 or ≥28. A significant association with poor prognostic factors was found among these patients. Multivariate analysis determined that significant risk factors for outliers of ΔKi-67 were tumor size >1 cm, negative progesterone receptor (PR expression, grade III cancer, and age ≤35 years. Among 171 patients with luminal human epidermal growth factor receptor 2-negative tumors, breast cancer subtype according to preoperative or postoperative Ki-67 levels discordantly changed in 46 (26.9% patients and a significant proportion of patients with discordant cases had ≥1 risk factor.Ki-67 expression showed a substantial concordance between biopsy and surgical specimens. Extremely discordant Ki-67 levels may be associated with aggressive tumor biology. In patients with luminal subtype disease, clinical application of Ki-67

Full Text Available Background. Survivin is an inhibitor of apoptosis protein involved in the regulation of cell proliferation that could be used as a marker for cancer diagnosis or prognosis. Our aim was to evaluate whether serum survivin levels influence the outcome of cisplatin-based chemotherapy in patients with malignant mesothelioma (MM. Methods. Serum survivin levels were determined using human survivin enzyme-linked immunosorbent assay in 78 MM patients before chemotherapy, after chemotherapy, and at disease progression. The influence on tumor response and survival was evaluated using nonparametric tests and Cox regression. Results. A median serum survivin level at diagnosis was 4.1 (0–217.5 pg/mL. Patients with a progressive disease had significantly higher survivin levels before chemotherapy (p = 0.041. A median serum survivin level after chemotherapy was 73.1 (0–346.2 pg/mL. If survivin levels increased after chemotherapy, patients had, conversely, better response (p = 0.001, OR = 5.40, 95% CI = 1.98–14.72. Unexpectedly, patients with increased survivin levels after chemotherapy also had longer progression-free (p < 0.001, HR = 0.33, 95% CI = 0.20–0.57 and overall survival (p = 0.001, HR = 0.29, 95% CI = 0.14–0.58. Conclusions. These results suggest that serum survivin levels before and during chemotherapy could serve as a biomarker predicting MM treatment response.

Full Text Available Cryptorchidism is the most common congenital birth defect in boys and affects about 2–4% full-term male neonates. Its etiology is multifactorial. Purpose. To evaluate the serum bisphenol A (BPA levels in boys with cryptorchidism and healthy boys and to assess the risk of environmental exposure to BPA using the authors’ questionnaire. The data were acquired from a study on boys with cryptorchidism (n=98 and a control group (n=57. Prior to surgery, all patients had BPA serum levels evaluated. The size, position, rigidity of the testis, and abnormality of the epididymis of the undescended testis were assessed. Parents also completed a questionnaire on the risks of exposure to BPA in everyday life. Results. The testes in both groups were similar in size. The turgor of the undescended testis in the group of boys with cryptorchidism was decreased. Free serum BPA level in cryptorchid boys and in the control group was not statistically significant (p>0.05. The conjugated serum BPA level in cryptorchid boys and in the control group was statistically significant (p≤0.05. Total serum BPA level in cryptorchid boys and in the control group was statistically significant (p<0.05. Serum total BPA level was related with a positive answer about problems with conception (p<0.02. Conclusion. Our study indicated that high serum BPA was associated with cryptorchidism.

Serum total bilirubin levels and coronary heart disease--Causal association or epiphenomenon?

Kunutsor, Setor K

2015-12-01

Observational epidemiological evidence supports a linear inverse and independent association between serum total bilirubin levels and coronary heart disease (CHD) risk, but whether this association is causal remains to be ascertained. A Mendelian randomization approach was employed to test whether serum total bilirubin is causally linked to CHD. The genetic variant rs6742078--well known to specifically modify levels of serum total bilirubin and accounting for up to 20% of the variance in circulating serum total bilirubin levels--was used as an instrumental variable. In pooled analysis of estimates reported from published genome-wide association studies, every copy of the T allele of rs6742078 was associated with 0.42 standard deviation (SD) higher levels of serum total bilirubin (95% confidence interval, 0.40 to 0.43). Based on combined data from the Coronary Artery Disease Genome wide Replication and Meta-analyses and the Coronary Artery Disease (C4D) Genetics Consortium involving a total of 36,763 CHD cases and 76,997 controls, the odds ratio for CHD per copy of the T allele was 1.01 (95% confidence interval, 0.99 to 1.04). The odds ratio of CHD for a 1 SD genetically elevated serum total bilirubin level was 1.03 (95% confidence interval, 0.98 to 1.09). The current findings casts doubt on a strong causal association of serum total bilirubin levels with CHD. The inverse associations demonstrated in observational studies may be driven by biases such as unmeasured confounding and/or reverse causation. However, further research in large-scale consortia is needed. Copyright © 2015 Elsevier Inc. All rights reserved.

Chemerin is a recently identified adipokine suggested to play a role in obesity and its metabolic complications. The relationship between visceral obesity and serum chemerin levels in type 2 diabetes (T2DM) is unknown and may differ from that of subjects without diabetes. Therefore, we evaluated whether serum chemerin was associated with visceral abdominal obesity in patients with T2DM. A total of 218 Korean patients with T2DM were enrolled and metabolic parameters, abdominal visceral and subcutaneous fat areas, and serum chemerin levels were measured. Serum chemerin level showed positive correlation with fasting insulin, HOMA-IR, serum triglyceride, serum creatinine, urine albumin/creatinine ratio, high-sensitivity C-reactive protein (hsCRP), fibrinogen, abdominal visceral fat area, visceral to subcutaneous fat area ratio, and negatively correlation with high density lipoprotein cholesterol and creatinine clearance (CCr) after adjusting for age, gender and body mass index. Multiple linear stepwise regression analysis showed that abdominal visceral fat area (β = 0.001, P abdominal visceral fat area, serum triglyceride, hsCRP and fibrinogen and lower level of CCr in patients with T2DM. Serum chemerin may be used as a biomarker of visceral adiposity and chemerin may play a role in inflammation, decreased renal function, and increased cardiovascular risk in T2DM.

In this article, postplenectomy changes of serum tufstin level were studied on both human subjects and rabbits by using a self-established radioimmunoassay protocol. Anituftsin antibodies were raised in rabbits and roosters. 125 I-tufstin was prepared through an Iodogen method. The characterristics of the RIA were satisfactory with a detecting range of 0.5-100 ug/ml and the lowest detection limit of 400ng/ml. Serum tufstin levels of splenectomized subjects were measured and compared with control groups. The serum tufstin level from 30 postsplenectomy human beings was 406 ± 179 ng/ml (x ± s) while that from a control group of 40 healtly blood donors was 557 ± 256 ng/ml; the serum tufstin level of 10 postsplenectomy rabbits was found to be 206 ± 75 ng/ml while that of a control group of 10 normal rabbits was 318 ± 96 ng/ml. The results showed that serum tufstin level decreased markedly after splenectomy. (author). 5 refs., 1 fig., 2 tabs

In order to find out the correlations between serum leptin levels and viral hepatitis, the serum leptin levels in 167 patients with viral chronic hepatitis, 87 patients with fatty liver, and 80 control subjects were determined by radioimmunoassay. The liver function (ALT, AST), glucose(Glu) and total cholesterol(TC) in these patients were also measured. Compared with controls and patients with fatty liver, the levels of serum leptin in patients with viral hepatitis were significantly increased (P 0.05). The increase of serum leptin levels in the patients with viral hepatitis was correlated positively with the severity of liver inflammation. Therefore, the leptin can be regarded as an indicator to reflect the severity of liver inflammation. (authors)

Full Text Available Background: Obesity is a well-known principal risk factor for metabolic disorders and cardiovascular diseases. Resistin is one of adipocyte-derived molecules, which plays important roles in inflammation as well as in endocrine and cardiovascular systems. Objectives: The present study aimed to determine the association between serum resistin level and presence/severity of Coronary Heart Disease (CHD. Patients and Methods: This cross-sectional study was conducted on 155 individuals referred for coronary angiography. Information about the patients’ age, gender, and cardiovascular risk factors was recorded. Their weight, height, and waist and hip circumferences were measured, as well. Each coronary angiogram was reported for two scoring methods (number of vessel diseases (usual method and Gensini scoring system by one cardiologist who was not aware of the participants’ serum resistin levels. Then, the relationship between serum resistin level and presence/severity of CHD was evaluated. Results: The results revealed no significant associations between the mean serum resistin level and the presence of CHD by both methods of evaluation of the coronary angiograms after adjustment for all conventional risk factors for CHD. In addition, no significant association was detected between serum resistin level and the severity of CHD based on the usual method of reporting the coronary angiograms (number of vessel diseases (P = 0.332. Yet, serum resistin level was positively correlated to body mass index and waist and hip circumferences and negatively related to height and fasting blood sugar level. Moreover, no linear correlation was found between serum resistin level and Gensini score (P = 0.35. Finally, hip circumference (P = 0.002 and height (P = 0.018 were determined as the predictors of serum resistin level. Conclusions: This cross-sectional study showed no significant associations between serum resistin level and presence/severity of CHD.

Obesity is a condition in which the body fat stores are increased to an extent which impairs health and leads to serious health consequences. The amount of body fat is difficult to measure directly, and is usually determined from an indirect measure - the body mass index (BMI). Increased BMI in obese persons is directly associated with an increase in metabolic disease, such as type 2 diabetes mellitus. This Analytical cross sectional study was undertaken to assess the relation between obesity and glycemic control of body by measuring fasting serum glucose and glycosylated hemoglobin. This study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh from 1st July 2011 to 30th June 2012 on 120 equally divided male and female persons within the age range of 25 to 55 years. Age more than 55 years and less than 25 years and diagnosed case of Hypothyroidism, Cushing's syndrome, polycystic ovary, Antipsychotic drug user and regular steroid users were excluded. Non probability purposive type of sampling technique was used for selecting the study subjects. Measurement of body mass index was done as per procedure. Fasting serum glucose was estimated by glucose oxidase method and Glycosylated hemoglobin by Boronate Affinity method. Statistical analysis was done by SPSS (version 17.0). Data were expressed as Mean±SE and statistical significance of difference among the groups were calculated by unpaired student's 't' test and Pearson's correlation coefficient tests were done as applicable. The Mean±SE of fasting serum glucose was significant at 1% level (P value obese group of BMI. There was no significant difference of glycosylated hemoglobin level between control and study groups.

Objective: To explore the role of the cytokines interleukin-2 (IL-2), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in the neuroimmune modulation of epilepsy through measurement of the changes of the serum levels of the these cytokines after drug therapy in epileptic patients. Methods: Serum IL-2, IL-6, TNF-α levels were measured with RIA in 43 patients with epilepsy both before and after drug therapy for 3-6 months as well as 32 controls. Results: Before treatment, serum levels of these cytokines in the patients were significantly higher than those in the controls (p<0.001). After treatment, 18 of the 43 patients were regarded as treatment very successful, with attack numbers decreased more than 75%. Some of this group of patient had their serum cytokines levels significantly dropped down, but the mean level for the group as a whole did not change much. In the rest 25 patients with less successful result, changes were not significant with the levels increased in a few cases. Among the cytokines, levels of IL-2 were significantly positively correlated to those of IL-6 and TNF-α (r=0.47, p<0.01, r=0.55, p<0.01). Conclusion: Increased levels of the cytokines in the epileptic patients suggest an activated immune state. However, the changes of levels after therapy are not predictable and do not necessarily drop down significantly even with very successful treatment

Full Text Available Asthma is one of the most common chronic disorders among children. Zinc (Zn is an essential dietary antioxidant and may have a special role in assisting the airways of asthmatic subjects. The primary objective of this study was to measure serum Zn levels among asthmatic school children and to compare this to the serum Zn level in non-asthmatic children. The secondary objective was to investigate the relationship between Zn levels and the degree of asthma control. A cross-sectional study following forty asthmatic children and forty matched non-asthmatic children of both genders was conducted. Weight, height, body mass index (BMI, BMI Z-scores, serum Zn, hemoglobin, total protein, and albumin concentrations were measured in both groups. Serum immunoglobulin E (IgE levels, the forced expiratory volume in 1 second (FEV1, and dosage of inhaled steroids were measured in asthmatic school children. The results show the mean Zn level among asthmatic children was 12.78 ± 1.8 μmol/L. Hypozincemia was detected in four asthmatic children. Asthma and control groups were matched in age, gender, and BMI Z score (p > 0.05. No significant difference was observed in Zn levels, hemoglobin, albumin, and total protein between both groups (p > 0.05. Among asthmatics, Zn levels were not significantly associated with the degree of asthma control (well controlled, mean Zn = 12.9 ± 1.5, partially controlled, mean Zn = 11.9 ± 1.6, and uncontrolled, mean Zn = 3.62 ± 2.2 (p = 0.053. The Zn level was not correlated with the FEV1 Z score. There was no significant association between Zn level and the dosage of inhaled steroids or IgE concentrations (p > 0.05. The findings show that Zn may not play a major role in the degree of asthma control. Larger studies are needed to confirm these results.

This research sought to summarize the evidence regarding the relationship between serum zinc level and metabolic syndrome (MetS). The electronic databases of PubMed, Web of Science, and Embase were searched up to October 2017 for observational studies on the association between serum zinc level and MetS. The standard mean difference (SMD) and its corresponding 95% confidence interval (CI) of the serum zinc level for MetS versus control participants were calculated. In addition, the pooled odds ratio (OR) and relative risk (RR) of MetS for the highest versus lowest category of serum zinc level, as well as their corresponding 95% CI, were also calculated. A total of 11 observational studies (8 cross-sectional, 1 case-control, and 2 cohort studies) were included in this meta-analysis. The combined SMD demonstrated that the serum zinc level in MetS was higher than that in control participants (SMD = 0.11; 95% CI, 0.03-0.19; p = 0.009). Moreover, the overall multivariable-adjusted RR showed that the increased serum zinc level was associated with a higher risk of MetS (RR = 1.82; 95% CI, 1.33-2.50; p level and MetS (OR = 1.00; 95% CI, 0.99-1.01; p = 0.841). Although the serum zinc level in participants with MetS was significantly higher than that in control ones, the existing evidence was still insufficient to conclude a definite relationship between serum zinc level and MetS. More well-designed prospective cohort studies are needed to elaborate the concerned issues further.

Coronary heart disease is a major public health problem. Elevated triglyceride levels are a risk factor for atherosclerosis and coronary heart disease. Food intake interferes with the measurement of serum triglyceride levels, and in previous studies, fasting for 12 hours was recommended before blood sampling. In real-world practice, long fasting times cause patient discomfort and poor compliance, and the present study was, therefore, designed to determine the appropriate fasting time prior to measuring serum triglyceride levels. To determine the appropriate fasting time before measuring serum triglyceride levels. This was a pilot study performed using healthy volunteers aged between 20 and 30 years old from November 2013 to December 2013 at Rajavithi Hospital. The first blood sample was measured in the morning after fasting over 12 hours. The subjects then took their regular breakfast, after which they fasted for 8 hours. Blood samples were taken 6 and 8 hours later and sent to the laboratory for measurement of serum triglyceride levels. 40 volunteers, of whom 25 were female, were enrolled. Their mean age was 25.9 ± 2.81 years old, and their mean weight, height, and body mass index were 61.5 ± 12.5 kg, 167.2 ± 8.3 cm and 21.84 ± 3.1 kg/m2, respectively. Mean fasting serum triglyceride level at 12 hours was 80.23 ± 36.33 mg/dl, at 6 hours it was 110.65 ± 73.45 mg/dl, and at 8 hours it was 75.62 ± 46.81 mg/dl. The group fasting for 12 hours had significantly lower serum triglyceride levels than the group fasting for 6 hours (p-value = 0.003), but no significant difference was found between the group fasting for 12 hours and the one fasting for 8 hours (p-value = 0.493). The present study showed no significant difference in triglyceride levels in patients who had fasted or 8 hours and those who had done so for 12 hours. Fasting for only 8 hours before measurement of serum triglyceride may be sufficient.

Objective: To investigate the serum leptin concentration in polycystic ovary syndrome (PCOS) with hyperandrogenemia (HA) and its relationship with testosterone (T) level and body mass index (BMI). Methods: Serum leptin levels were measured by radioimmunoassay in 53 patients with PCOS, in which 36 cases were of the in non-obesity group and 17 cases in obese group. 30 non-obese cases and 20 obese cases without PCOS served as controls. Results: The levels of leptin in PCOS with HA in obese and non-obese group were significantly higher than those in control group (all p < 0.01). There was a positive correlation between serum leptin levels and testosterone levels in both groups (r = 0.51, p < 0.01 and r = 0.58, p < 0.01). No correlation existed between serum leptin levels and body mass index (BMI) in PCOS patients of non-obese group but there was positive correlation in obesity group (r = 0.56, p < 0.01). Conclusion: High serum leptin levels is one of the characteristic in PCOS patients. The HA in PCOS patients is related to serum leptin levels and heavyweight or obese patients have the phenomenon of leptin resistance

The main objective of the study was to evaluate the endocrinological picture of anorexia. Serum leptin levels are low in untreated anorexia nervosa (AN), but studies of the exact relationship between leptin, body weight and hormones of hypothalamo-hypophyseal-thyroid axis and the impact of refeeding in anorectics are limited. The sample consistent of 15 patients with anorexia nervosa before and 1 month after partial weight recovery, and 15 age-matched control subjects. The body mass index (BMI), leptin, plasma neuropeptide Y (NPY), serotonin, thyroxine (T4), triiodothyronine (T3) and reverse triiodothyronine (rT3) in serum were evaluated for each subject. The mean serum levels of leptin, T4, and T3 were significantly lower before weight recovery in 15 patients with AN than they were in control subjects. After partial weight recovery, basal T3 levels were unchanged and significantly lower than in controls. Basal T4 was even still more reduced, but we observed significantly elevated ratio of T3/T4 and reduced ratio rT3/T4 of in AN patients after gain recovery, indicating increased conversion of T4 to T3 than to rT3. The levels of serum leptin were low in AN, but after partial weight recovery slightly increased, and correlated with BMI. No differences were observed in serum NPY. Serum levels of IGF-1 and serotonin were lower in AN than in controls before and after partial weight gain. IGF-1 was slightly increased after partial weight gain. We did not find correlation between serum levels of leptin and serum T4. The low serum levels of T3 associated with chronic starvation were thought to be the result of impaired peripheral conversion of T4 to T3. However, decreased levels of T3 were still apparent even after a partial weight gain, and the concentration of T4 was even lower. The diminished serum level of TSH in AN, however, appeared to return to the level of controls. On the basis of these results, we assume that low serum levels of thyroid hormones in AN reflect a

In the present study, we investigated the relationship between depressive symptoms and serum zinc and magnesium level in antepartum and postpartum women. All women received standard vitamin, zinc and magnesium supplementation. Sixty-six pregnant women in the Czerwiakowski Hospital in Kraków were assessed for prepartum depressive symptoms using the Beck Depression Inventory (BDI). Sixty-two and fifty-eight women were also assessed for postpartum depressive symptoms (using Edinburgh Postnatal Depression Rating Scale, EPDRS) at 3 and 30 days after delivery, respectively. Serum zinc and magnesium levels were also determined at these time points, however, the number of examined subjects were diminished. A significantly higher EPDRS score (by 45%), indicating severity of depressive symptoms, was found on the 3rd day after childbirth compared with the 30th postpartum day. Moreover, the early post-delivery period (3rd day) was characterized by a 24% lower serum zinc concentration than that found on the 30th day after childbirth. BDI scores assessed a month before childbirth revealed mild depressive symptoms, which was accompanied by a serum zinc concentration similar to that found on the 3rd day after delivery. No significant alterations were found in the magnesium levels between these time points. The present results demonstrated a relationship between severity of depressive symptoms and decreased serum zinc (but not magnesium) concentration in a very specific type of affective disorder, the postpartum depression.

AIM: To investigate the association between serum alpha-fetoprotein (AFP) levels and fatty liver disease (FLD) in a Chinese population. METHODS: A cross-sectional study was performed among subjects who presented for a health examination at the First Affiliated Hospital, College of Medicine, Zhejiang University in 2013. FLD was diagnosed based on an ultrasonography examination. Serum AFP levels were measured with a chemiluminescence immunoassay. RESULTS: Of the 9800 subjects enrolled, 2601 were diagnosed with FLD. Subjects with FLD had higher serum AFP levels than those without the disease. Subjects with high serum AFP levels had a higher prevalence of FLD, metabolic syndrome, and its components. Univariate logistic analysis showed that elevated serum AFP levels were associated with an increased risk of FLD (OR = 1.057, 95%CI: 1.031-1.084). However, after adjusting for covariates, AFP no longer remained significantly associated with the risk factors for FLD. CONCLUSION: Our results suggest that serum AFP levels are significantly associated with FLD and that AFP acts as a cofactor, but not as an independent factor, for FLD. PMID:25206293

During the past three decades, the incidence of hepatocellular carcinoma in the United States has tripled. The neuroendocrine character has been observed in some tumor cells within some hepatocellular carcinoma nodules and elevated serum chromogranin A also been reported in patients with hepatocellular carcinoma. The aim of this work was to investigate the role of serum concentration of chromogranin A in patients with hepatocellular carcinoma at different stages. The study population consisted of 96 patients (63 males and 33 females age range 52-84) at their first hospital admission for hepatocellular carcinoma. The control group consisted of 35 volunteers (20 males and 15 females age range 50-80). The hepatocellular carcinoma patients were stratified according the Barcelona-Clinic Liver Cancer classification. Venous blood samples were collected before treatment from each patients before surgery, centrifuged to obtain serum samples and stored at -80° C until assayed. The chromogranin A serum levels were elevated (> 100 ng/ml) in 72/96 patients with hepatocellular carcinoma. The serum levels of chromogranin A were significantly correlated (p<0.05) with alpha-fetoprotein. In comparison with controls, the hepatocellular carcinoma patients showed a significant increase (p<0.001) vs controls. The chromogranin A levels in the Barcelona staging of hepatocellular carcinoma was higher in stage D compared to stage C (p<0.01), to stage B (p<0.001), and to stage A (p<0.001). Molecular markers, such as chromogranin A, could be very useful tools for hepatocellular carcinoma diagnosis. However the molecular classification should be incorporated into a staging scheme, which effectively separated patients into groups with homogeneous prognosis and response to treatment, and thus serves to aid in the selection of appropriate therapy.

Postoperative myocardial infarction (PMI) is one of the most serious complications of cardiac surgeries. No preoperative biomarker is currently available for predicting PMI after cardiac surgeries. In the present study, we used a phage display peptide library to screen potential preoperative peptide biomarkers for predicting PMI after coronary artery bypass grafting (CABG) surgery. Twenty patients who developed PMI after CABG and 20 age-, sex-, and body mass index-matched patients without PMI after CABG were enrolled as a discovery cohort. Another 50 patients who developed PMI after CABG and 50 randomly selected patients without PMI after CABG were enrolled as a validation cohort to validate the potential peptide biomarkers identified in the discovery cohort. Fifty randomly selected healthy volunteers were also enrolled in the validation phase as a healthy control group. In the discovery/screening phase, 17 out of 20 randomly selected phage clones exhibited specific reaction with purified sera IgG from the PMI group, among which 11 came from the same phage clone with inserted peptide sequence GVIMVIAVSCVF (named PMI-1). In the validation phase, phage ELISA showed that serum IgG from 90% of patients in the PMI group had a positive reaction with PMI-1; in contrast, only 14% and 6% of patients in the non-PMI group and the healthy control group had a positive reaction with PMI-1, respectively. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of the PMI-1 phage clone to preoperatively identify patients who would develop PMI after CABG were 90.0%, 86.0%, 86.5, 89.5% and 88.0%, respectively. The absorbance value of the PMI-1 phage clone showed statistically significant correlation with the peak postoperative serum cardiac troponin I level (r = 0.349, p = 0.012) in the PMI group. In conclusion, we for the first time identified a mimic peptide (PMI-1) with high validity in preoperative prediction of PMI after CABG. PMID

Serum prohepcidin levels were measured using a commercial enzyme-linked immunosorbent assay kit (DRG International, Inc. Marburg, Germany; ferritin was studied with chemiluminescence method (Immulite 2000 DPC. Results: Mean serum ferritin levels in TM, TI and control groups were 2347.97±1724.81 ng/mL (range: 144-8015 ng/mL, 1352.40±918.94 ng/mL (range: 311-3109 ng/mL, and 33.35±12.03 ng/mL (range: 20-69.1 ng/mL, respectively. Serum prohepcidin levels in the same groups were 221.78±74.38 ng/mL (range: 7l.14-446.57 ng/mL, 173.31±52.14 ng/mL (range: 100.83-267.69 ng/mL, and 218.20±50.37 ng/mL (range: 116.18-330.43 ng/mL, respectively. There was a statistically significant difference in prohepcidin levels between patients with TI and control group only (p=0.016. No correlation was found between prohepcidin and ferritin levels in all groups (r=-0.023, p=0.839. Conclusion: Low levels of prohepcidin in patients with TI may be related to increased erythropoietic activity. Prohepcidin can be an indicator of active erythropoiesis.

Objective: To study the changes of levels of serum cortisol and gastrin in dogs with vibration-induced injury for providing better treatment regimen. Methods: In this experiment, 8 or 10 domestic dogs were placed on each of four sites away from explosion center about 0, 100, 200, 300 meters respectively. The dogs were standing uncontrolled or lying right side down under anesthesia. Serum cortisol and gastrin levels were detected with RIA both before and after explosion. Results: The levels of serum cortisol and gastrin began to fall about 24 hours after explosion. The serum levels of cortisol were still decreased significantly after 9 days and 17 days. Conclusion: The levels of the serum cortisol declined when the animals were injured by vibration. Detection of serum cortisol levels might lead to definitive diagnosis and supplemental treatment with cortical hormones for vibration-induced injury. (authors)

The thyroid hormones possibly exert a reciprocal action between testicular steroids and Sertoli's cells during the premature period. This work aims to evaluate thyroxine effect on testosterone serum levels and in the testicular interstitial fluid (TIF) in rats. Wistar males rats, 22 days old, 80g of body weight, were induced to hyperthyroidism with thyroxine (20μg/kg) in periods of 5, 10, 15 and 20 consecutive days. After the treatment the animals were weighed and sacrificed for blood and testis collection. From the blood serum and from the TIF drained from the testis were performed testes in order to obtain testosterone attached to 125 I with a specific activity of 36,86 MBq/ig. The results have shown a testosterone significant lineal increase in both - serum and TIF - in the group treated with thyroxine as a time function. In the control group, testosterone levels remained low in both serum and TIF dosages. As a result, we were able to verify that the testosterone levels could be modified by thyroxine in serum and TIF. And so, it could affect luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels in hypophysis. (author)

smoking is an important risk factor for placental abruption with strong dose-dependency. Pregnant smokers often underreport tobacco use which can be objectively assessed by measuring serum cotinine levels. We examined the accuracy between self-reported smoking habits and early pregnancy serum cotinine levels in women with or without placental abruption. retrospective case-control study. university Hospital. a total of 175 women with placental abruption and 370 control women. serum samples collected during the first trimester were analyzed for serum cotinine levels. Cotinine concentration over 15 ng/ml was considered as the cutoff indicating active smoking. Smoking habits of the women and their partners were recorded at the same visit. placental abruption. of the cases of women with placental abruption, 27.4% reported smoking compared with 14.3% of the controls (p smoked daily correlated well with the cotinine levels (r = 0.68, p smoking habits correlate well with serum cotinine levels in Finland. Therefore, self-reported smoking can be considered as a risk marker for placental abruption.

In order to clarify the mechanism of osteogenesis and osteopenia of the menopausal women, serum [Ca 2+ ], [P 3+ ], AKP, sexual hormones and BGP level were investigated. The blood samples were taken from 177 female individuals who were divided into 5 groups based on different ages of menopause. Serum estradiol, testosterone and BGP were measured by RIA. Serum LH, FSH and PRL were determined by IRMA. Serum [Ca 2+ ], [P 3+ ], AKP were determined by biochemistry analytical methods. Results showed that serum E 2 and T levels in the menopausal women were lower than those in the normal, E 2 decreased significantly. Meanwhile, serum PRL level was only a little lower, but the menopausal female had the higher levels of LH and FSH. Conclusion: the most important cause of osteopenia for the menopausal women is the deficiency of estrogen and degeneration of ovarian function

Full Text Available Serum cholinesterase levels are closely correlated with the severity of liver disease. The aim of the paper was to assess the value of serum cholinesterase in evaluating liver reserve function in cirrhotic patients. 90 patients with liver cirrhosis and thirty healthy control group were included. Liver cirrhosis patients were classified according to child score into three equal groups: Child A liver cirrhosis, Child B liver cirrhosis and Child C liver cirrhosis. Patients were subjected to clinical evaluation, laboratory analysis, abdominal U/S. Measuring serum cholinesterase, and Calculation of both Child and model of end stage liver disease (MELD scores. The level of serum cholinesterase was higher in control group than the three groups of liver cirrhosis with median (IQR 17,410 (12,111-21,774, 7528 (5200-9856, 6021 (4500-7542, 3828.5 (1541-6060, respectively P<0.001. And the level of serum cholinesterase was higher in Child A more than Child B and Child C and the level of serum cholinesterase was higher in Child B more than Child C with very strong negative correlation between serum Cholinesterase level and Child score (r=-0.9, P<0.001. Also strong negative correlation between serum Cholinesterase level and MELD score (r=- 0.85, P=0.001, and positive correlation with prothrombin concentration (r=0.554, P=0.009, and serum albumin levels (r=0.582, P=0.0002. Serum cholinesterase is a good biomarker of cirrhosis. Since it distinguishes decompensated from compensated cirrhosis well, low levels in cirrhosis may serve as a useful prognostic marker of advanced liver disease.

Full Text Available Dry eye syndrome (DES is a common tear film and ocular surface disease that results in discomfort, visual disturbance, and tear film instability with potential damage to the ocular surface. Systemic diseases associated with DES include diabetes mellitus, rheumatoid arthritis, depression, anxiety, thyroid disease, allergic diseases, irritable bowel syndrome, chronic pain syndrome, and hyperlipidemia. Interestingly, it has been found that most of these are associated with low levels of serum 25-hydroxyvitamin D (25(OHD or inadequate sunlight exposure.In this cross-sectional data analysis, noninstitutionalized adults aged ≥19 years (N = 17,542 who participated in Korean National Health and Nutrition Examination Survey 2010-2012 were included. Information regarding duration of sunlight exposure was collected from the survey participants. Serum 25(OHD and zinc levels were measured. The confounding variables were age, gender, sunlight exposure time, region of residence, obesity, serum 25(OHD level, diabetes mellitus, rheumatoid arthritis, depression, thyroid disorder, atopic dermatitis, history of ocular surgery, regular exercise, and walking exercise.Mean serum 25(OHD levels of subjects with and without DES were 16.90 ± 6.0 and 17.52 ± 6.07 (p<0.001. Inadequate sunlight exposure time (odds ratio [OR], 1.554; 95% confidence interval [CI], 1.307-1.848, urban residence (OR, 1.669; 95% CI, 1.456-1.913, indoor occupation (OR, 1.578; 95% CI, 1.389-1.814, and low serum 25(OHD level (OR, 1.158; 95% CI, 1.026-1.308 were the risk factors for DES.

Circulating levels of melatonin in patients with traumatic brain injury (TBI) have been determined in a little number of studies with small sample size (highest sample size of 37 patients) and only were reported the comparison of serum melatonin levels between TBI patients and healthy controls. As to we know, the possible association between circulating levels of melatonin levels and mortality of patients with TBI have not been explored; thus, the objective of our current study was to determine whether this association actually exists. This multicenter study included 118 severe TBI (Glasgow Coma Scale melatonin, malondialdehyde (to assess lipid peroxidation) and total antioxidant capacity (TAC) at day 1 of severe TBI. We used mortality at 30 days as endpoint. We found that non-survivor (n = 33) compared to survivor (n = 85) TBI patients showed higher circulating levels of melatonin (p melatonin levels predicted 30-day mortality (Odds ratio = 1.334; 95% confidence interval = 1.094-1.627; p = 0.004), after to control for GCS, CT findings and age. We found a correlation between serum levels of melatonin levels and serum levels of TAC (rho = 0.37; p melatonin levels in patients with severe TBI. The main findings were that non-survivors had higher serum melatonin levels than survivors, and the association between serum levels of melatonin levels and mortality, peroxidation state and antioxidant state.

A radioimmunoassay specific for human aldolase A was used to measure human aldolase A levels in human tissue and serum of patients with various liver diseases. The method was a double-antibody technique using radio-iodinated purified aldolase A, chicken antibody to aldolase A, and rabbit antibody to chicken immunoglobulin G. Normal liver tissue contains only a small amount of aldolase A. In contrast, aldolase A predominates in liver cell carcinoma tissue. Aldolase A levels in the sera of normal subjects were 171 +/- 39 ng/ml (mean +/- 2 SD). In almost all of the nonmalignant liver diseases, the aldolase A levels remained less than 210 ng/ml. The serum aldolase A levels increased remarkable only in fulminant hepatitis. in contrast, 32 of 34 patients with liver cell carcinoma and all of 29 patients with metastatic liver carcinoma showed clearly increased serum aldolase A levels. More patients with primary liver cell carcinoma had increased serum aldolase A levels than elevations of serum alpha-fetoprotein. These results suggest that the determination of aldolase A by radioimmunoassay may be useful to differentiate malignant form nonmalignant liver diseases

Chromogranin A is an important tool in the diagnosis of neuroendocrine tumors. Autoimmune gastritis is an autoimmune disorder marked by hypergastrinemia, which stimulates enterochromaffin-like cell proliferation. Chromogranin A is also elevated in autoimmune gastritis patients with a different level of increase in each patient. The goal of this study is to explore constituents that influence serum chromogranin A levels in autoimmune gastritis patients. One hundred and eighty-eight autoimmune gastritis patients and 20 patients with type I gastric carcinoid tumors were analyzed retrospectively and compared to 110 functional dyspepsia patients in terms of factors that might affect serum chromogranin A levels. The mean serum chromogranin A level was 171.17±67.3 ng/mL in autoimmune gastritis patients (n=62) without enterochromaffin-like cell hyperplasia, and 303.3±102.82 ng/mL in patients (n=126) with enterochromaffin-like cell hyperplasia (pgastritis were the presence of ECL cell hyperplasia and serum gastrin levels. Serum chromogranin A levels maybe helpful in distinguishing autoimmune gastritis patients and gastric carcinoid type I from the control group, but not useful in the differentiation of individuals with autoimmune gastritis from patients with gastric carcinoids.

Introduction Chemokine (C-C motif) ligand 18 (CCL-18) has been shown to be elevated in chronic obstructive pulmonary disease (COPD) patients. This study primarily aimed to evaluate whether the serum CCL-18 level differentiates the frequent exacerbator COPD phenotype from infrequent exacerbators. The secondary aim was to investigate whether serum CCL-18 level is a risk factor for exacerbations requiring hospitalization. Materials and methods Clinically stable COPD patients and participants with smoking history but normal spirometry (NSp) were recruited for the study. Modified Medical Research Council Dyspnea Scale, COPD Assessment Test, spirometry, and 6-min walking test were performed. Serum CCL-18 levels were measured with a commercial ELISA Kit. Results Sixty COPD patients and 20 NSp patients were recruited. Serum CCL-18 levels were higher in COPD patients than those in NSp patients (169 vs 94 ng/mL, PCOPD (168 vs 196 ng/mL) subgroups did not achieve statistical significance (P=0.09). Serum CCL-18 levels were significantly higher in COPD patients who had experienced at least one exacerbation during the previous 12 months. Overall, ROC analysis revealed that a serum CCL-18 level of 181.71 ng/mL could differentiate COPD patients with hospitalized exacerbations from those who were not hospitalized with a 88% sensitivity and 88.2% specificity (area under curve: 0.92). Serum CCL-18 level had a strong correlation with the frequency of exacerbations requiring hospitalization (r=0.68, PCOPD, as it is associated with frequency of exacerbations, particularly with severe COPD exacerbations requiring hospitalization, as well as with functional parameters and symptom scores.

The aim of this study was to investigate a possible role for interleukin-6 (IL-6) and tumour necrosis factor (TNF-alpha) as pre-operative markers for the diagnosis of ovarian torsion. Twenty consecutive patients admitted to the gynaecological emergency room with suspected clinical diagnosis of ovarian torsion were prospectively assigned to the study. Blood samples were drawn pre-operatively and examined for serum concentrations of IL-6 and TNF-alpha. Surgeons were blinded to laboratory results prior to laparoscopy. The pre-operative diagnosis of ovarian torsion was confirmed during an urgent diagnostic laparoscopy in 8 (40%) patients. The surgical diagnosis among the remaining 12 patients was a large ovarian cyst not in torsion. In six out of eight (75.0%) patients with ovarian torsion serum IL-6 concentrations were elevated. None of the 12 patients without torsion had elevated serum IL-6 concentrations. This difference was statistically significant (P < 0.001). There was no significant difference in the proportion of women with elevated serum TNF-alpha concentrations, two of eight (25.0%) patients with torsion and four of 12 (33.3%) control cases. Elevated serum IL-6 concentrations, but not serum TNF-alpha concentrations, were significantly associated with the occurrence of ovarian torsion. In patients with vague clinical signs of ovarian torsion, serum IL-6 might help to distinguish which patients should undergo diagnostic laparoscopy.

Full Text Available Introduction: Noise exposure may have anatomical, nonauditory, and auditory influences. Considering nonauditory impacts, noise exposure can cause alterations in the automatic nervous system, including increased pulse rates, heightened blood pressure, and abnormal secretion of hormones. The present study aimed at examining the effect of various sound pressure levels (SPLs on the serum aldosterone level among rats. Materials and Methods: A total of 45 adult male rats with an age range of 3 to 4 months and a weight of 200 ± 50 g were randomly divided into 15 groups of three. Three groups were considered as the control groups and the rest (i.e., 12 groups as the case groups. Rats of the case groups were exposed to SPLs of 85, 95, and 105 dBA. White noise was used as the noise to which the rats were exposed. To measure the level of rats’ serum aldosterone, 3 mL of each rat’s sample blood was directly taken from the heart of anesthetized animals by using syringes. The taken blood samples were put in labeled test tubes that contained anticoagulant Ethylenediaminetetraacetic acid. In the laboratory, the level of aldosterone was assessed through Enzyme-linked immunosorbent assay protocol. The collected data were analyzed by the use of Statistical Package for Social Sciences (SPSS version 18. Results: The results revealed that there was no significant change in the level of rats’ serum aldosterone as a result of exposure to SPLs of 65, 85, and 95 dBA. However, the level of serum aldosterone experienced a remarkable increase after exposure to the SPL of 105 dBA (P < 0.001. Thus, the SPL had a significant impact on the serum aldosterone level (P < 0.001. In contrast, the exposure time and the level of potassium in the used water did not have any measurable influence on the level of serum aldosterone (P = 0.25 and 0.39. Conclusion: The findings of this study demonstrated that serum aldosterone can be used as a biomarker in the face of sound

Serum heat-stable alkaline phosphatase (HSAP) level in 649 cases of normal pregnancy and 164 cases of high-risk pregnancy is measured by radioimmunoassay (RIA). The results indicate that the HSAP level in normal pregnancy increased proportionally with gestation weeks (r = 0.9843). In 33 cases of pregnancy induced hypertension and 21 cases of intrauterine fetal growth retardation, the HSAP level is significantly low. In 7 cases of neonatal asphyxia and 26 cases of fetal distress, the HSAP level in the mother's serum is also low. In 53 cases of intrahepatic cholestasis of pregnancy, the HSAP level is similar to those of normal pregnancy. This study illustrates that HSAP RIA can play an important role in the evaluation of placental function and fetal prognosis for cases of high-risk pregnancy

The idiopathic basal ganglia calcification (Fahr syndrome) may occur due to senility. Fetuin-A is a negative acute phase reactant which inhibits calcium-phosphorus precipitation and vascular calcification. In this study, we aimed to evaluate whether serum fetuin-A levels correlate with bilateral basal ganglia calcification. Forty-five patients who had bilateral basal ganglia calcification on brain CT were selected according to the inclusion and exclusion criteria, and 45 age and gender-matched subjects without basal ganglia calcification were included for the control group. Serum fetuin-A levels were measured from venous blood samples. All participants were divided into two groups; with and without basal ganglia calcification. These groups were divided into subgroups regarding age (18-32 and 33-45 years of age) and gender (male, female). We detected lower levels of serum fetuin-A in patients with basal ganglia calcification compared with the subjects without basal ganglia calcification. In all subgroups (female, male, 18-32 years and 33-45 years), mean fetuin-A levels were significantly lower in patients with basal ganglia calcification (p = 0.017, p = 0.014, p = 0.024, p = 0.026, p = 0.01 respectively). And statistically significantly lower levels of fetuin-A was found to be correlated with the increasing densities of calcification in the calcified basal ganglia group (p-value: <0.001). Considering the role of fetuin-A in tissue calcification and inflammation, higher serum fetuin-A levels should be measured in patients with basal ganglia calcification. We believe that the measurement of serum fetuin-A may play a role in the prediction of basal ganglia calcification as a biomarker. Copyright © 2017 Elsevier B.V. All rights reserved.

Full Text Available Objective: To investigate the impact of serum 25-hydroxyvitamin D levels on migraine headache in migraineurs Patients and Methods: A total of 72 patients were included in the study. Serum vitamin D concentration and its impact on the migraine headache were assessed in migraineurs and migraine subgroups. To assess serum levels of vitamin D, 25(OH D3 was measured by enzymelinked immunosorbent assay (ELISA. Patients were categorized as follows based on the results of serum vitamin D measurements. Severity of migraine, average duration and frequency of attacks per month were recorded. The headache diary result (HDR was determined as: Duration of headache × frequency of headache. Results: Average vitamin D level was 7.4 ng/ml among patients with migraine with aura group and 8.5 ng/ml in patients with migraine without aura. Severe vitamin D deficiency was detected in 14 (66.7% patients with migraine with aura and 9 (64.3% patients with migraine without aura, with no statistically significant difference between the two groups. No significant correlation was found between vitamin D levels and HDR among migraineurs (r=-0.042, p=0.812 as well as in patients with migraine with aura (r=0.044, p=0.842 and in patients with migraine without aura (r=0.059, p=0.842 versus control group with respect to HDR and vitamin D levels. The severity of migraine pain was not associated with vitamin D levels. Serum vitamin D concentration was lower in male patients versus control group. Conclusion: The impact of vitamin D on the severity and number of migraine attacks is not clear. Further studies are needed to demonstrate the association between vitamin D status and neurological diseases.

To compare the serum AMH levels between women with and without insulin resistance (IR) in polycystic ovary syndrome (PCOS). 293 women with PCOS according to the Rotterdam criteria were enrolled into our study. Insulin resistance was diagnosed according to the Homeostatic model assessment insulin resistant (HOMA-IR) formula and the cut-off point was set to more than 2.5. Women were grouped according to the presence of insulin resistance (IR) (HOMA-IR ≥ 2.5). Serum AMH and other hormones were compared between the IR (+) and IR (-) groups. Additionally, AMH percentiles were (75) constructed; HOMA-IR and BMI values in women with/without IR were compared in different percentiles. Further, HOMA-IR, BMI and AMH values were measured across different PCOS phenotypes. The prevalence of IR was 45%. The prevalence of IR was 57% in women with BMI ≥ 25. Serum AMH levels were not significantly different among women with and without IR. Also, HOMA-IR values were not significant among different AMH percentiles. However, in each AMH percentile BMI were found to be higher in women with IR than in women without IR. The median HOMA-IR values were the highest in women with BMI ≥ 25 in both IR (+) and IR (-) groups. No significant difference was found among PCOS phenotypes in terms of HOMA-IR and BMI. Positive correlations were found between BMI, free testosterone and HOMA-IR. However, no correlation was found between AMH and HOMA-IR. The serum AMH levels between women with IR and without IR in PCOS were not significantly different. Also, we did not reveal a correlation between serum AMH levels and IR in women with PCOS. IR was not correlated with different PCOS phenotypes either. We found a positive correlation between BMI and IR. IR should be investigated in women with PCOS having a BMI ≥ 25, independent of their phenotype or AMH levels. Copyright © 2018 Elsevier B.V. All rights reserved.

The aim of our study was to measure and compare serum insulin-like growth factor-1 (IGF-1) levels at postmenstrual age of 33 weeks between preterm infants with and without retinopathy of prematurity (ROP). ROP occurs in two phases. Low serum levels of IGF-1 during ROP phase 1 have been found to correlate with the severity of ROP. ROP phase 2 begins around postmenstrual week 33. We conducted a prospective cohort study to measure serum IGF-1 levels in premature infants at postmenstrual age of 33 weeks. The study included all premature infants (N = 74), gestational age large controlled study with repeated measurement of IGF-1 level in the neonatal period is needed to confirm that restoration of IGF-I level occurs in ROP phase 2, i.e. that the low level of IGF-1 is only a feature of ROP phase 1.

To evaluate serum and aqueous humor levels of fetuin-A in patients with pseudoexfoliation syndrome (PEXS) in comparison with those of age- and sex-matched healthy subjects. This prospective study included 25 patients with PEXS and 25 control subjects who were undergoing cataract surgery without any systemic or ocular disease. Aqueous humor and serum fetuin-A levels were measured with enzyme-linked immunosorbent assay method. The mean age of the PEXS group (14 males, 11 females, n = 25) was 57.7 ± 6.9 years, and the control group (13 males, 12 females, n = 25) was 58.1 ± 5.7 years. There was no difference between the groups in terms of age (p = 0.77) and sex (p = 0.83). The mean serum fetuin-A level of the PEXS group did not differ from that of the control group (p = 0.53). The mean aqueous humor level of the PEXS group was significantly higher than that of the control group (p = 0.032). There were no significant correlations between aqueous humor and serum fetuin-A levels among patients with PEXS and control group (p > 0.05). Increased levels of fetuin-A in aqueous humor of patients with PEXS may show the local effect of fetuin-A on the anterior segment. With considering the wide range of possible biological functions of fetuin-A in the pathogenesis of PEXS, further studies are needed to clarify the clinical relevance of these findings.

Helicobacter pylori is associated with higher virulence. TNF-α has an important role in host defense against H. pylori infection. The aim of this study was to investigate the relationship between TNF-α serum levels with cagA and vacA genes in H. pylori infection. This was a cross-sectional study involving 80 patients that consecutively admitted to endoscopy unit. Diagnosis of H. pylori infection was based on rapid urease test. Serum samples werecollected to determine circulating TNF-α level. Polymerase chain reaction was done to examine H. pylori vacA and cagA genes. Data analysis was carriedout using SPSS version 22 with 95%CI and p<0.05 was considered statistically significant. About 45 (56.3%) patients infected with Helicobacter pylori. There were 33 (73.3%) patients with H. pylori cagA positive. Serum TNF-α levels in patients with the H. pylori positive were significantly higher compared to H. pylori negative. Serum level of TNF-α was significantly higher in cagA positive than negative. Subjects with H. pylori cagA gene positive were more likely to have ahigher level of serum TNF-α than H. pylori cagA gene negative.

Full Text Available Objective: To analyze the relationship of serum adipocytokine levels with glucolipid metabolism and micro-inflammatory state in obese children. Methods: A total of 299 obese children and 264 normal children were included in the study, fasting peripheral venous blood was extracted to determine serum levels of adipocytokines, glucolipid metabolism and microinflammation-related indexes, and the correlation between the levels of adipocytokines and the levels of glucolipid metabolism and micro-inflammation-related indexes was further analyzed. Results: Serum leptin and Vaspin levels of observation group were higher than those of control group, and APN level was lower than that of control group (P<0.05; serum FINS, C-P, Cor, TG and LDL-C levels were higher than those of control group, and HDL-C level was lower than that of control group (P<0.05; serum hs-CRP, IL-8, IL-6 and TNF-α levels were higher than those of control group (P<0.05; serum Leptin, APN and Vaspin levels were directly correlated with the levels of above glucolipid metabolism and micro-micro-inflammatory state indexes. Conclusions: There are high expression levels of inflammatory factors and glucolipid metabolism disorder in obese children, and excessively expressed adipocytokines may be the important factors of persist and worsened obesity.

Brominated flame retardants (BFRs) is a group of environmental chemicals for which lately both interest and knowledge have increased considerably. Among the BFRs, the polybrominated diphenyl ethers (PBDEs) have attained special interest. Much data on environmental and human levels have been presented and several toxicological reviews are now published. Among interesting results is the difference in human PBDE levels that seem to exist between U.S.A. and Europe, results that suggest differences in exposure but without being able to pin-point the exact sources. In experimental studies PBDEs alter serum thyroxin levels, an effect seen both in rats and in mice. The mechanism(s) are still not completely clarified, but are thought to include alterations in serum transport, induced enzymatic degradation and possibly also direct effects on the thyroid gland. As perinatal alterations in thyroid homeostasis could affect brain development, early effects on thyroid hormones may be of special concern. Indeed, PBDEs have been shown to affect behaviour and learning in mice, when given neonatally. The aim of the present study was to relate the serum levels of PBDEs in rats to effects of these compounds on thyroxine homeostasis in these animals. Specifically, the relation between serum PBDE levels and effects on serum thyroxine levels was investigated, after two weeks of daily oral exposure. The result may have consequences for the future risk assessment activities on PBDE and specifically in finding the critical serum PBDE concentration at which the effect on thyroid hormone levels begin to occur.

Increase of Serum amyloid A (SAA) level has been observed in patients with a variety of cancers. The objective of this study was to determined whether SAA level could be used as a prognostic parameter in patients with esophageal squamous cell carcinoma (ESCC). SAA levels were measured by rate nephelometry immunoassay in 167 healthy controls and 167 ESCC patients prior to surgical resection. Statistical associations between clinicopathological observations and SAA levels were determined using the Mann–Whitney U test. The clinical value of SAA level as a prognostic parameter was evaluated using the Cox’s proportional hazards model. SAA levels were significantly higher in patients with ESCC compared to levels in healthy controls (13.88 ± 15.19 mg/L vs. 2.26 ± 1.66 mg/L, P < 0.001). Elevation of SAA levels (≥ 8.0 mg/L) was observed in 54.5% (91/167) of patients with ESCC but not in healthy controls. SAA levels were associated with tumor size (P < 0.001), histological differentiation (P = 0.015), T classification (P < 0.001), clinical stage (P < 0.001), lymph node metastasis (P < 0.001) and distant metastasis (P < 0.001), but not with the age and gender of the patients or tumor location. Multivariate analysis revealed that patients with an elevated level of SAA (≥ 8.0 mg/L) had significantly lower 5-year survival rate than those with non-elevated SAA (< 8.0 mg/L, log-rank P < 0.0001). An elevated level of preoperative SAA was found to associate with tumor progression and poor survival in patients with ESCC
