RESUMEN
While investigating psychosocial factors on resilience and post-traumatic growth draws attention, research on biological correlates is limited. We investigated the relationship between post-traumatic growth, resilience, post-traumatic stress, and potential biomarkers in female patients with breast cancer (n = 71) from the general surgery or oncology clinics. They completed the Post-Traumatic Growth Inventory (PTGI), Connor Davidson Psychological Resilience Scale (CD-RISC), Brief Resilience Scale (BRS), PTSD Checklist for DSM-V, and Hospital Anxiety and Depression Scale. Blood samples were collected for NPY, ALLO, DHEA-S, testosterone, cortisol, and hsCRP levels. The relationship between biochemical parameters and the scales was investigated in the whole patient group and in the subgroup of patients who perceived breast cancer as traumatic. When all the patients were evaluated, hsCRP and depression scores were significantly and positively correlated; and hsCRP, BRS score, and PTGI change in self-perception subscale score were significantly and negatively correlated. There was a significant positive correlation between the ALLO level and the psychological resilience (CD-RISC) score in the patient group who perceived breast cancer as traumatic. It was observed that psychological resilience and PTG were positively correlated, and that multiple biomarkers were associated with psychological resilience in female breast cancer patients. Especially findings regarding ALLO levels and psychological resilience could be a new target for future research.

INTRODUCTION: The present study aimed to investigate the role of plasma presepsin in the early detection of septic shock and in determining the prognosis and mortality of patients with sepsis. METHODOLOGY: The study was conducted in the emergency department between 1 January 2017 and 1 July 2017. A total of 106 patients 18 years of age or older who were diagnosed with sepsis according to the quick sequential organ failure assessment (qSOFA) criteria were included in this prospective study. The patients' symptoms, vital signs, additional diseases, demographic attributes, laboratory results, Mortality in Emergency Department Sepsis (MEDS) scores, imaging findings and treatments were recorded. Moreover, the patients' blood samples were collected to measure plasma presepsin, procalcitonin and CRP levels. RESULTS: In total, 55.7% of the patients were female. The median age of the patients was 78 (24-103) years, and their 30-day mortality rate was 67%. The presepsin level was significantly higher in the sepsis group than in the healthy control group (p < 0.001). The presepsin levels did not differ significantly between the sepsis and septic shock groups (p = 0.12). Similarly, the procalcitonin levels did not differ significantly between the sepsis and septic shock groups (p > 0.05). There was no significant difference in the presepsin, procalcitonin and CRP levels between survivor and non-survivor patients (p = 0.74). CONCLUSIONS: The plasma presepsin level was found to be ineffective in determining the incidence of septic shock and mortality in patients with sepsis in the emergency department.

Osteoprotegerin has been shown to be increased in cardiovascular disorders and type 2 diabetes mellitus. Prediabetes represents a high risk condition for diabetes and diabetic complications. Therefore, we aimed to find the relationship between prediabetes and osteoprotegerin with nuclear factor-B ligand, carotid intima media thickness, and metabolic markers. A total of 54 participants with prediabetes including impaired fasting glucose (n = 21), impaired glucose tolerance (n = 8), impaired fasting glucose and impaired glucose tolerance (n = 25), and 60 healthy individuals as a control were admitted to the study. Metabolic and anthropometric parameters, insulin resistance variables, osteoprotegerin, and nuclear factor-B ligand markers, carotid intima media thickness were examined at baseline for all participants. To evaluate the effect of therapy we determined the same parameters after the end of the study. Measurements of waist circumference, body mass index, body fat percentage and levels of fasting blood glucose, fasting insulin, homeostatic model assessment of insulin resistance, triglyceride levels and hsCRP and carotid intima media thickness were significantly higher in patients with prediabetes (p < 0.05). We also found higher osteoprotegerin and lower nuclear factor-B ligand levels in patients than in controls however, the value was non-significant (p > 0.05). Patients with prediabetes were under lifestyle interventions with (group 1, n = 33) or without metformin (group 2, n = 21) therapy. Baseline anthropometric and metabolic characteristics were not found statistically different in group 1 and group 2. Mean follow up period of the patients were 7.9 ± 2.2 month (min-max: 6-12 months). After the follow up period we evaluated the same parameters and found significant differences between waist circumference, body mass index, body fat percentage, fasting insulin, homeostatic model assessment of insulin resistance, and osteoprotegerin levels (p < 0.05). However, carotid intima media thickness, and nuclear factor-B ligand levels significantly different only in the group treated with metformin (p < 0.05). We also compared the variables after the treatment period with the control group and found significantly lower levels in terms of fasting insulin, homeostatic model assessment of insulin resistance, waist circumference, body mass index, body fat percentage, carotid intima media thickness, osteoprotegerin, and nuclear factor-B ligand values (p < 0.05). Correlation analysis revealed a negative relationship between nuclear factor-B ligand and body mass index, and body fat percentage in group 1 (p = 0.05, r = -0.646, p = 0.01, r = -0.585). Therapy of prediabetes was associated with a significant decrease in osteoprotegerin and certain metabolic variables together with an increase in nuclear factor-B ligand levels particularly in patients with under metformin therapy.

Background Hyperemesis gravidarum, which affects 0.3-2.3% of pregnancies, is defined as excessive vomiting during pregnancy and usually starts in week 4 or 5 of gestation. Symptoms include weight loss, dehydration, ketonaemia, ketonuria, fasting acidosis, alkalosis due to hydrochloric acid loss and hypokalaemia and its exact cause is unknown. The present study was undertaken to investigate the relationship between prealbumin, ghrelin, nesfatin-1 and obestatin concentrations in pregnancies associated with hyperemesis gravidarum. Methods A total of 40 pregnant females with hyperemesis gravidarum and 38 pregnant females without hyperemesis gravidarum as controls were included in this study. Serum concentrations of prealbumin, ghrelin, obestatin and nesfatin-1 were measured. Results There were no significant differences in age, gestational week, gravidity and parity between the two groups. Body mass index was significantly lower in cases than in controls. Serum ghrelin and prealbumin concentrations were significantly lower in cases than in controls ( P <0.05 and P < 0.001, respectively). There was no significant difference in serum concentrations of obestatin and nesfatin-1 between the two groups. There was no significant association between body mass index and serum ghrelin, nesfatin-1, obestatin or prealbumin concentrations in patients with hyperemesis gravidarum. Conclusions Decreased serum concentrations of ghrelin and prealbumin in patients with hyperemesis gravidarum are independent of body mass index. Based on our results, we believe that ghrelin may be considered to play a role in the aetiopathogenesis of hyperemesis gravidarum and that hyperemesis gravidarum may result in disruption of the relationship between nesfatin-1 and ghrelin. In addition, we believe that the measurement of serum prealbumin may be used for assessing nutritional status in pregnancy.

BACKGROUND: Liver biopsy is an invasive procedure that is currently still necessary for predicting underlying hepatic injury related to chronic viral hepatitis B (CVHB). To date, none of the studied non-invasive methods have been able to replace liver biopsy. An apoptotic serum marker, M30, which has been reported to indicate ongoing liver fibrosis, has been popular in recent years. OBJECTIVES: We aimed to investigate the possible role of M30 in predicting CVHB-associated hepatic injury and its severity. METHODS: Forty-eight patients undergoing liver biopsy for evaluation of the severity of CVHB-related liver injury and 40 healthy controls were included in this cross-sectional study. M30 levels were determined for all CVHB patients and controls, and other laboratory parameters and demographic features were obtained from our hospital's database. RESULTS: The mean ages of patients and controls were 39.7 and 45.7 years, respectively, and 35% of the controls and 52% of the patients were male. In contrast to lower platelet counts, transaminase and M30 levels were both higher in the patient group than in the controls. Among the investigated parameters, only transaminase increased as the fibrosis stage changed from mild to moderate; however, none of the laboratory parameters, including M30, differed as the histological activity index (HAI) score increased. CONCLUSIONS: M30 levels were higher in CVHB patients compared to healthy controls. However, M30 levels were similar in the mild and moderate stages of fibrosis, so they did not indicate the severity of underlying fibrotic or inflammatory processes in CVHB patients.
RESUMEN
INTRODUCTION: Isotretinoin has been successfully used for the treatment of acne vulgaris. AIM: To investigate the effects of isotretinoin on body mass index (BMI), to determine whether isotretinoin causes any changes in serum adiponectin, leptin, and ghrelin levels in acne vulgaris patients, and to correlate variables. MATERIAL AND METHODS: Thirty-two patients were included in this study. Oral isotretinoin was begun at a dose of 0.5-0.6 mg/kg and raised to 0.6-0.75 mg/kg. Pretreatment and posttreatment third-month BMI and adiponectin, leptin, and ghrelin serum levels were measured. RESULTS: The pre- and posttreatment BMI values were not significantly different. In addition, serum adiponectin and leptin levels were significantly increased following isotretinoin therapy while serum ghrelin levels were not different. CONCLUSIONS: Isotretinoin may exert its anti-inflammatory activity by increasing leptin and adiponectin levels.
RESUMEN
BACKGROUND: Vitamin D deficiency or insufficiency is a highly prevalent condition worldwide. Anesthesia providers or support personnel working in operating rooms might be considered at increased risk of vitamin D deficiency. There is a small amount of information about 25(OH)D levels in people who work mainly indoors as an operating room. This study aimed to investigate whether there was a higher vitamin D insufficiency or deficiency rate among anesthesia personnel working indoors when compared with personnel working in an office or outdoors in Ankara, Turkey (39 degrees North, 32 degrees East). METHODS: This study consisted of 125 volunteer anesthesia personnel and 60 subjects as control groups (30 outdoor workers and 30 office workers). All of the individuals completed a questionnaire. Serum levels of total 25(OH)D were measured by a chemiluminescent immunoassay method. RESULTS: 74.4% of anesthesia personnel and 76.6% of control group 1 (outdoor workers) and 76.6% of control group 2 (office workers) had serum 25(OH)D concentrations < 10 ng/mL. 20.8% of anesthesia personnel and 23.4% of control group 1 and 23.4% of control group 2 had serum 25(OH)D concentrations levels 10 - 20 ng/mL. 4.8% of anesthesia personnel had serum 25(OH)D concentration levels 21 - 30 ng/mL. There was no significant difference in the mean serum 25(OH)D level between the groups (Anesthesia group: 8.98 ± 4.89 ng/mL, Control group 1: 8.18 ± 2.39 ng/mL, Control group 2: 8.37 ± 3.01 ng/mL) (p > 0.05). CONCLUSIONS: To our knowledge the present study is the first study to investigate the comparison of vitamin D levels of anesthesia personnel with outdoor and office workers. Our findings alarmingly emphasize that vitamin D deficiency is very common at the end of winter in Ankara, regardless of being anesthesia personnel in operating room or a worker in office or an outdoor worker. Vitamin D supplementation may be suggested in all groups in Ankara.

BACKGROUND: Sample classification and registration have been recognized as important and time-consuming processes in laboratories. There is increasing pressure on laboratories to automate processes due to intense workload and reduce manual procedures and errors. The aim of the present study was to evaluate the positive effects of an automatic tube registration and sorting system on specimen processing. METHODS: An automatic tube registration and sorting system (HCTS2000 MK2, m-u-t AG, Wedel, Germany) was evaluated. Turnaround time (TAT), rate of sample rejection and unrealized tests were examined 12 months pre- and post-implementation of the automatic tube sorting and registration system. RESULTS: The mean TAT of routine chemistry immunoassay, complete blood cell count (CBC) and coagulation samples were significantly improved (P<0.001). The number of rejected samples and unrealized tests was insignificantly decreased post-implementation of the system (0.4% to 0.2% and 4.5% to 1.4%, respectively) (P>0.05). CONCLUSIONS: By reducing delays and errors in the preanalytical processing and sorting of samples, significant improvements in specimen processing were observed after implementation of the system. These results suggest that an automatic tube registration and sorting system may also be used to improve specimen processing in a higher-volume core laboratory.
RESUMEN
BACKGROUND: The aim of this study was to establish the protective effect of caffeic acid phenethyl ester (CAPE) against the ifosfamide (IFOS)-induced central neurotoxicity in rats and to determine the changes in oxidant-antioxidant status of brain tissue. METHOD: A total of 35 Wistar rats (aged 7-12 days) were used in the experiments. The study comprised of five groups. Control untreated rats (n = 7) belonged to group 1; group 2 was given intraperitoneal (IP) injection of CAPE alone (10 µmol/kg; n = 7); group 3 was treated with single IP injection of IFOS (500 mg/kg; n = 7); group 4 was treated for 2 days with IP administration of CAPE (10 µmol/kg) beginning from one day before single IP injection of IFOS (n = 7); and group 5 was treated with saline and 10% ethanol. At the 24th hour of IFOS treatment, brain tissues were removed for analysis. RESULTS: The brain catalase activity was lower in IFOS group than the other groups (p < 0.05). The levels of malondialdehyde (MDA) and protein carbonyl content in brain tissue were higher in IFOS group than the control, CAPE, ethanol, and IFOS + CAPE groups (p < 0.05). There was no significant difference between MDA and protein carbonyl content of control, CAPE, ethanol, and IFOS + CAPE groups. Immunohistochemistry showed marked activation of caspase 3 in the IFOS group at 24 h after treatment. CONCLUSION: This study revealed that pretreatment with CAPE might protect brain tissue against IFOS-induced central neurotoxicity. CAPE could be an effective course of therapy to enhance therapeutic efficacy and to lessen IFOS toxicity in clinical chemotherapy.

BACKGROUND: Studies investigating serum vaspin and adiponectin levels in patients with prolactinoma are inconclusive. The aim of this study was to evaluate serum vaspin and adiponectin levels in patients with prolactinoma and healthy controls. METHODS: A total of 42 prolactinoma patients (Group 1, 21 patients; Group 2, 21 patients) and 30 healthy controls were enrolled in the study. Group 1 consisted of newly diagnosed patients who were never treated or had not received a dopamine agonist (DA) within 6 months prior to screening. Group 2 consisted of prolactinoma patients who were on DA treatment for at least 6 months at the time of screening. The control group (group 3) consisted of healthy controls. RESULTS: Patients with prolactinoma had higher homeostasis model assessment of insulin resistance and lower quantitative insulin sensitivity check index values in comparison to healthy controls (p < 0.001 for both). Serum levels of adiponectin and vaspin were also significantly lower in prolactinoma patients when compared to the control group (p < 0.01 and p < 0.001, respectively). Following adjustment for confounding factors, the respective odds ratios for prolactinoma in patients in the lower subgroup compared with those in the higher subgroup for adiponectin and vaspin were 2.733 (0.621-12.035; p > 0.05) and 5.041 (1.191-21.339; p < 0.05). CONCLUSION: This is the first study to demonstrate the presence of low vaspin levels in patients with prolactinomas. Further studies are needed to help establish the roles of vaspin and adiponectin in prolactinoma patients.

Modulation of psoriasis severity by estradiol during pregnancy, menstruation and menopause has been investigated previously. The correlation between sex hormones and Psoriasis Area Severity Index (PASI) has not been studied in male psoriasis patients. We investigated serum sex hormones in male psoriasis patients compared with healthy controls and correlated these findings with PASI. Estradiol, testosterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels were measured in 47 male patients with psoriasis and 20 healthy controls. Patients with psoriasis showed higher body mass index and higher serum levels of FSH and LH relative to healthy controls, although this difference was not statistically significant. However, serum levels of testosterone and estradiol were significantly different between patients with psoriasis and healthy controls. Testosterone was significantly increased in control patients and estradiol was significantly increased among psoriatic patients. A significant inverse correlation was found between estradiol and PASI. Although the role of sex hormones in the pathogenesis of psoriasis has not been demonstrated, this is the first report of an inverse correlation between estradiol and PASI in male patients.

BACKGROUND: Early life-threatening cardiotoxicity and cardiac death have been reported after hematopoietic stem cell transplantation (HSCT). The purpose of the current study was to evaluate cardiac toxicity of conventional chemotherapy followed by HSCT with cardiac markers: heart-type fatty acid binding protein (H-FABP), glycogen phosphorylase BB (GPBB), high sensitive C reactive protein (hsCRP) cardiac troponin I, (cTnI), creatine kinase MB (CK-MB mass) and myoglobin. METHODS: A total of 20 children who underwent HSCT for malignant and non-malignant diseases were included in this study. Blood samples were collected from all patients in 0th, 7th and 21st day for evaluating these cardiac biomarkers. The patients' echocardiography was assessment before and after one-month of HSCT. RESULTS: Serum 21st H-FABP level was significantly higher when compared with the 0th day H-FABP level (P < 0.05) . 7th day hsCRP level was significantly higher than 0th and 21st day levels (P < 0.05). Interestingly, 7th day GPBB level was significantly lower than 0th and 21st day levels (P < 0.05). Myoglobin, CK-MB mass and cTnI biomarkers remained within the reference range in all patients. CONCLUSIONS: This study showed that H-FABP and hsCRP both seem to be promising markers for evaluation of cardiotoxicity in HSCT process and probably superior to GPBB, cTnI, CK-MB mass and myoglobin.

OBJECTIVE: The etiology and pathogenesis of hyperemesis gravidarum (HG) is still undetermined and has been suggested to involve oxidative stress. We aimed to evaluate the status of oxidative stress in HG by measuring the levels of total oxidant status (TOS), total antioxidant status (TAS), and by calculating the oxidative stress index (OSI). METHODS: In a case-control trial, fasting morning blood samples of patients with HG (n = 41) and healthy pregnant women (n = 39) were collected for analysis of serum TOS and TAS values as well as for calculation of OSI according to the formula: OSI = TOS / TAS × 100. RESULTS: Serum TOS and TAS levels were similar in both groups. However, serum TAS levels were lower among HG patients compared to controls, which resulted in an increase in OSI (P = 0.025). DISCUSSION: The present study supports the role of systemic oxidative stress, reflected by an imbalance between the TOS and TAS, in patients with HG. Our findings distinguish the mechanism underlying oxidative stress to result from reduction of antioxidants rather than an increase in oxidants.

The chondroitin sulfate proteoglycans (CSPGs) aggrecan, versican, and brevican are large aggregating extracellular matrix molecules that inhibit axonal growth of the mature central nervous system (CNS). ADAMTS proteoglycanases, including ADAMTS4 and ADAMTS5, degrade CSPGs, representing potential targets for ameliorating axonal growth-inhibition by CSPG accumulation after CNS injury. We investigated the proteolysis of CSPGs in mice homozygous for Adamts4 or Adamts5 null alleles after spinal cord injury (SCI). ADAMTS-derived 50-60 kDa aggrecan and 50 kDa brevican fragments were observed in Adamts4-/-, Adamts5-/-, and wt mice but not in the sham-operated group. By contrast Adamts4-/- and Adamts5-/- mice were both protected from versican proteolysis with an ADAMTS-generated 70 kDa versican fragment predominately observed in WT mice. ADAMTS1, ADAMTS9, and ADAMTS15 were detected by Western blot in Adamts4-/- mice' spinal cords after SCI. Immunohistochemistry showed astrocyte accumulation at the injury site. These data indicate that aggrecan and brevican proteolysis is compensated in Adamts4-/- or Adamts5-/- mice by ADAMTS proteoglycanase family members but a threshold of versican proteolysis is sensitive to the loss of a single ADAMTS proteoglycanase during SCI. We show robust ADAMTS activity after SCI and exemplify the requirement for collective proteolysis for effective CSPG clearance during SCI.

BACKGROUND AND AIM: Early detection of fibrosis should be the main goal of treatment in liver cirrhosis. Endocan, previously called endothelial cell specific molecule-1, is expressed by endothelial cells, primarily in the lung, liver and kidney. In this study, we aimed to examine the correlation of liver fibrosis stage, histological activity and grade of steatosis between serum levels of endocan in patients with chronic hepatitis B (CHB), chronic hepatitis C (CHC) and non-alcoholic fatty liver disease (NAFLD). PATIENTS AND METHODS: This cross-sectional study includes a total of 146 subjects. 55 CHB patients, 19 CHC patients, 38 NAFLD patients and 34 healthy controls were enrolled consecutively. Liver biopsies were performed in all patients with chronic viral hepatitis. NAFLD patients had either grade 2 or grade 3 steatosis on ultrasonography and elevated liver enzymes above the upper normal limits. Serum endocan levels were assessed from blood samples obtained at admission. RESULTS: Gender distribution was similar among the groups (p=0.056). The mean age of the CHB patients was 45.8±12.1, CHC patients was 55.0±12.8 years, NAFLD patients was 42.8±10.8, while control group was 39.4±13.6 years old. Patients with CHC were older than all the others (p=0.001). Serum endocan levels were statistically significantly lower in CHB, CHC and NAFLD groups when compared with controls. Although levels of endocan were lower in CHB and CHC groups when compared with NAFLD group, the difference was not statistically significant. CONCLUSION: Serum endocan concentrations decrease in patients with liver disease. Unlike previous studies, we showed a negative correlation between endocan levels and inflammation stage of chronic hepatitis. However, further studies are needed to establish the association between endocan levels, liver fibrosis and hepatic inflammation.
RESUMEN
Acute pancreatitis is the acute inflammation of pancreas and peripancreatic tissues, and distant organs are also affected. The aim of this study was to investigate the effect of Urtica dioica extract (UDE) treatment on cerulein induced acute pancreatitis in rats. Twenty-one Wistar Albino rats were divided into three groups: Control, Pancreatitis, and UDE treatment group. In the control group no procedures were performed. In the pancreatitis and treatment groups, pancreatitis was induced with intraperitoneal injection of cerulein, followed by intraperitoneal injection of 1 ml saline (pancreatitis group) and 1 ml 5.2% UDE (treatment group). Pancreatic tissues were examined histopathologically. Pro-inflammatory cytokines (tumor necrosis factor-α), amylase and markers of apoptosis (M30, M65) were also measured in blood samples. Immunohistochemical staining was performed with Caspase-3 antibody. Histopathological findings in the UDE treatment group were less severe than in the pancreatitis group (5.7 vs 11.7, p = 0.010). TNF-α levels were not statistically different between treated and control groups (63.3 vs. 57.2, p = 0.141). UDE treatment was associated with less apoptosis [determined by M30, caspase-3 index (%)], (1.769 vs. 0.288, p = 0.056; 3% vs. 2.2%, p = 0.224; respectively). UDE treatment of pancreatitis merits further study.
RESUMEN
Many noninvasive serum markers have been studied to determine the liver fibrosis score (LFS). In this study, we aimed to investigate the association between thrombopoietin (TPO) levels and the stage of liver fibrosis in patients with chronic hepatitis B (CHB). Seventy-seven patients (64 active and 13 inactive) with CHB were included in this cross-sectional study. Patients were divided into three groups: In group 1, patients with mild or no fibrosis (F0, F1); in group 2, patients with significant fibrosis (F2-F4); and in group 3, inactive CHB carriers. Digital patient records were used to access pre-treatment laboratory findings including HBV DNA, HBeAg, ALT, AST, total bilirubin, PLT, albumin, INR. Liver biopsies were examined by experienced pathologists in our hospital who were blinded to the data of the patients. Serum TPO levels were measured using commercial ELISA kit. Serum TPO levels were significantly lower in patients with active CHB compared with the inactive carriers (528 vs 687.1 p=0.003). There was no statistically significant difference in TPO levels between the patients with and patients without significant fibrosis (568.9 vs 459.8 p=0.367). Correlation analysis with respect to ALT, AST, TPO, HBV-DNA level, platelet count, histological activity index (HAI) and liver fibrosis score was performed. TPO was only weakly positively correlated with AST, ALT and HBV-DNA levels (r=0.269 p=0.018; r=0.341 p=0.002; r=0.308 p=0.006; respectively) and no correlation in TPO with LFS and HAI was found (r=0.140 p=0.270, r=0.162 p=0.201; respectively). TPO was not associated with significant fibrosis (p=0.270). In conclusion, TPO levels were decreased in active CHB patients compared with inactive carriers but there was no correlation between TPO levels and the stage of fibrosis in active CHB.
RESUMEN
AIM: The purpose of this study was to search for the effects of adenotonsillectomy (A&T) on height, weight, and body mass index (BMI), as well as changes in ghrelin, leptin, and insulin-like growth factor 1 (IGF-1) levels in children with adenotonsillar hypertrophy (ATH)-related sleep-disordered breathing (SDB). METHODS: A study cohort of 39 children clinically diagnosed with ATH-related SDB was included in this study. Twenty-three healthy children were included as controls. Height and weight standard deviation scores (SDS) and ghrelin, leptin, and IGF-1 levels of the controls were determined once; in the study group, they were determined preoperatively and in the third month postoperatively. RESULTS: Preoperative IGF-1 (ng/mL) and ghrelin (pg/mL) levels were significantly higher in the patients than in the controls (322.51±113.10 vs. 256.96±176.73, p<0.05 and 106.08±9.75 vs. 80.11±28.50, p<0.001, respectively). The preoperative height and weight SDS values of the patients were lower than those of the controls (-0.67±1.36 vs. 0.13±1.13, p<0.05 and -0.38±1.35 vs. -0.20±1.29, respectively). The patients' postoperative height and weight SDS values were significantly higher than their preoperative values (-0.05±1.08 vs. -0.67±1.36, p<0.0001 and 0.00±1.28 vs. -0.38±1.35, p<0.0001, respectively). The mean postoperative IGF-1 levels also were significantly higher than preoperative levels (386.05±130.06 vs. 322.51±113.10, p<0.05, respectively). CONCLUSION: Plasma IGF-1 levels are lower in malnourished children, and plasma ghrelin levels are decreased after acute oral food intake and are increased in cachexia and fasting. Therefore, increased serum IGF-1 levels, height and weight SDS values, and decreased ghrelin levels detected postoperatively are useful parameters that help to monitor the development of children with adequate oral intakes.

Ifosfamide (IFOS) which is a cytotoxic alkylating agent may cause central nervous system toxicity. Alpha-lipoic acid (ALA) has a strong antioxidant effects. We hypothesized that ALA could attenuate on ifosfamide-induced central neurotoxicity in rats. Rats were divided into Control, IFOS, ALA and IFOS+ALA groups. The toxic effects of IFOS were analyzed by oxidative parameters and caspase 3 immunohistochemical examinations of brain tissue. The catalase activity of IFOS group significantly reduced in comparison with control groups (p < 0.05). The malondialdehyde (MDA) level and protein carbonyl (PC) content in brain tissue were significantly higher in IFOS group than in the other groups (p < 0.05). ALA treatments significantly prevented the increase in MDA level (p < 0.001) and PC content (p < 0.05) in brain tissue. IFOS group showed profound activation of caspase 3. The control, ALA and IFOS+ALA groups did not show caspase 3 activation. It was concluded that ALA treatments may have beneficial effects protecting neurons from central neurotoxicity caused by IFOS.

Neuroinflammatory events mediated by the pro-inflammatory cytokine tumor necrosis factor-alpha (TNF-α) cause progressive neurodegeneration in dopaminergic neurons, and play an important role in the pathogenesis of Parkinson's disease (PD). The purpose of this study was to determine TNF-α levels in tear samples obtained from patients with PD and to analyze the relationship between TNF-α values and PD characteristics. Eighteen patients with PD and 17 healthy control subjects were included in the study. We examined the patient demographics, modified Hoehn and Yahr Staging Scale (mHY) stages, Unified Parkinson's disease rating scale (UPDRS) II and III scores, Mini Mental State Examination (MMSE) scores, and the predominant symptoms. We measured TNF-α using the multiplex immunobead assay in unstimulated tear samples, and determined the Schirmer's test and blink rate for each subject. Tear TNF-α values were significantly higher in patients with PD (196.9 ± 121.2 pg/ml) than in control subjects (110.7 ± 87.2 pg/ml; p=0.02). We identified no relationship between tear TNF-α levels and age, sex, age at onset, PD duration, mHY stages, UPDRS II, UPDRS III, or MMSE scores. The higher TNF-α levels observed in the tears of patients with PD suggests neuroinflammation and TNF-α plays a role in the pathogenesis of PD. Tear TNF-α levels, however, were not related to the duration or severity of PD. Tears are a suitable method for measuring TNF-α levels, and can be used as a diagnostic measure to evaluate biomarkers in PD.
