The role of S100B protein, neuron-specific enolase, and glial fibrillary acidic protein in the evaluation of hypoxic brain injury in acute carbon monoxide poisoning

The main purpose of this study was to assess the role of S100B protein, neuron-specific enolase (NSE), and glial fibrillary acidic protein (GFAP) in the evaluation of hypoxic brain injury in acute carbon monoxide (CO)-poisoned patients. This cross-sectional study was conducted among the patients with acute CO poisoning who referred to the emergency department in a 1-year period. Serum levels of S100B protein, NSE, and GFAP were determined on admission. A total of 55 CO-poisoned patients (mean age ± standard deviation, 45 ± 20.3 years; 60% women) were included in the study. The control group consisted of 25 healthy adults. The patients were divided into two groups according to whether they were conscious or unconscious. The serum levels of S100B, NSE, and GFAP were higher in patients than that in the control group. There was no significant difference between unconscious and conscious patients with respect to these markers. There was a statistically significant difference between the conscious and unconscious patients and the control group in terms of S100B and NSE levels. There was also a statistically significant difference between the unconscious patients and the control group in terms of GFAP levels. Increased serum S100B, NSE, and GFAP levels are associated with acute CO poisoning. These biomarkers can be useful in assessing the clinical status of patients with CO poisoning.

AbstractPatients afflicted with melanoma show lower vitamin D serum levels (VDSL) than the healthy population. This hypothesis agrees with its well-known antiproliferative features. An observational study was carried out to collect VDSL in patients suffering from melanoma. Our aim was to identify a potential connection between low VDSL and the risk to incur melanoma. Furthermore, we studied the association between VDSL at the diagnosis of melanoma and other germane prognostic factors. The population held in regard was composed of 154 patients with a diagnosis of melanoma between 2016 and 2019. These patients were retrospectively collected from our follow-up storage. We compared VDSL to clinical and pathological parameters (age, sex, tumour location, Breslow’s depth, Clark’s level, histological subtype, ulceration, et aliqua). Moreover, we recruited a control group with negative melanoma history. Mean and median of VDSL were significantly lower in the melanoma group. Instead, we found a negative association between melanoma and VDSL > 30 ng/L (OR 0.11; p < 0.0001). No correlation between VDSL and both Breslow’s depth and Clark’s level was discovered, but the VDSL comparison between thin (depth ≤ 1 mm) and thick tumours (depth > 1 mm) revealed a statistically significant difference (21.1 ± 8.2 ng/L vs 17.8 ± 8.1; p = 0.01). Moreover, VDSL were significantly lower in melanomas with mitotic rate ≥ 1/mm2 (22.1 ± 8.3 ng/L; p < 0007). Nevertheless, no connection was found between VDSL and both ulceration and positive sentinel nodes (p = 0.76; p = 0.74). Besides, our study revealed no association between VDSL and histological subtype (p = 0.161). Lower VDSL correlate with thick and high mitotic rate tumours. Future prospective studies would investigate if appropriate upkeep of suitable VDSL can decrease the risk of primary and recurrent melanoma diagnosis.

Background Traumatic brain injury (TBI) seriously affects the quality of life of patients. The present study evaluated the role of diffusion tensor imaging (DTI) combined with Neuron-Specific Enolase (NSE) and S100 calcium-binding protein B (S100B) protein in predicting the prognosis of moderate and severe TBI. Methods The TBI patients were divided into moderate TBI (TBIm) and severe TBI (TBIs) groups according to the Glasgow Coma Scale (GCS) after admission. The patients were then divided into good and poor prognosis groups according to the Glasgow Outcome Scale (GOS); moreover, their follow-ups were recorded at 3 and 6 months after injury. This study also included 65 healthy individuals with matched age and gender as the control group. The fractional anisotropy (FA) values of DTI, serum neuron-specific enolase (NSE), and S100B protein levels were detected in this study. The data were analyzed in SPSS software (version 22.0) to evaluate the role of DTI combined with NSE and S100B protein in predicting the prognosis in TBIm and TBIs. Results: After TBI, the FA values of DTI in the TBI group were lower than those in the control group (P<0.05); moreover, the serum NSE and S100B values in the TBI group were higher than those in the control group (P<0.05). In the TBIm patients, the FA values of the corpus callosum in the good prognosis group were higher than that in the poor prognosis group (P<0.05); however, there was no significant difference between the two groups regarding the FA values of the internal capsule and the cerebral peduncle (P>0.05). The serum levels of NSE and S100B in the good prognosis group were significantly lower than those in the poor prognosis group (P<0.05). In the TBIs patients, the FA value of all areas in the good prognosis group was significantly higher than that in the poor prognosis group (P<0.05). However, there was no significant difference between the two prognosis groups regarding the serum levels of NSE and S100B (P>0.05). Conclusion Although DTI combined with NSE and S100B protein can effectively predict the prognosis of patients with moderate and severe TBI in the early stages, various other measures have been used in the studies to predict the prognosis of TBI patients. Accordingly, comparison with other measures is essential in further studies.

We investigated serum levels of alpha-2-macroglobulin (α2—MG) and some of its complexes, namely α2-MG-plasmin (α2-MG— Pl) and α2-MG—IgG at a rheumatoid arthritis (RA) 2—3 degrees of activity (65 patients), a system lupus erythematosus (SLE) of 2-3 degrees of activity (30 patients) and 55 healthy donors as a control group. It is shown, that at SLE the total level of α2-MG is invariable, and at RA — decreases significantly in comparison with the healthy. The concentration of complexes was raised at pathology, but at RA this rising was expressed much more strongly, than at SLE. At studying of correlations of levels of α2-MG, α2-MG—Pl and α2-MG— IgG among themselves and with some several cytokines and acute phase proteins, it is shown, that there is some significant difference between normal and pathological correlative relations and allows us to suspect that at SLE, the α2-MG and its complexes participate in a pathogenesis, and at RA α2-MG becomes the major immunogenesis factor and the significant reason of disease progression.

Objective: The objective of this research was to study the possible role of renalase in the controlling blood pressure (BP) in patients with different stages of chronic kidney diseases (CKD) to decrease the incidents of cardiovascular disease in these patients.Methods: The serum levels of renalase were determined by enzyme-linked immune sorbent assay (ELISA) methods in 68 non-diabetic CKD patients in different stages (2–5). Fifty healthy control subjects were included in this study. Renalase high-sensitive C-reactive protein and Cystatin-C were measured by ELISA which is included first incubating the test serum in an antigen-coated polystyrene plate, then enzyme-labeled anti-immunoglobulin is added and the enzyme then remaining in plate after washing provides a measure of the amount of specific antibody in the serum, and in the final step, a substance is added that the enzyme can convert to some detectable signal, most commonly a color change in a chemical substrate.Results: There were a significant difference between serum levels of renalase, in CKD patients stage 5, and CKD patients 2–3 stage than in their healthy control group (p<0.05), in addition to a significant difference in renalase level between CKD stage, 2–3 and stage 5 (p<0.05). There was a significant positive correlation between serum renalase with systolic BP (p<0.05) in CKD patients stage 5. In addition, there was a significant negative correlation between the serum renalase and estimated glomerular filtration rate (p<0.05) in both groups.Conclusions: The main conclusion of the study was the positive significant correlation with systolic BP in CKD patients (stage 5). In addition, the serum renalase levels were elevated according the CKD stage in patients with CKD in different stages (2–5) and it increased with the deterioration of renal function.

Abstract Background Meningiomas are one of the most common tumors of the brain and central nervous system. The key role of endocan in predicting tumor growth and prognosis has been shown for several types of cancers; however, this role in meningiomas has not been evaluated. In the current study, we investigated the relationship between endocan serum levels with low- and high-grade meningiomas. Results The serum level of endocan in the group with meningiomas was 283.34 (242.09-358.70) pg/ml and in the control group was 250.29 (207.56-329.71) pg/ml respectively (P = 0.172). Afterwards, patients were divided into three different groups (grades I, II, and III) and compared to the control. The level of endocan in the group with grade I of meningioma showed no significant difference compared to control individuals (P = 0.86). When patients with grade II and grade III compared with the control group, endocan serum levels were statistically significant (P = 0.002, P < 0.001 respectively). Moreover, our findings showed that the different grades of meningiomas were statistically significant compared to each other (P < 0.001) regarding endocan serum levels, meaning that the higher the grade, the higher the endocan serum levels. Conclusion Our findings revealed that higher grades of meningioma had higher endocan serum levels, however, the role of endocan in pathogenesis or progression of this type of tumor requiring further exclusively assessment.

Background. The role of gender for nephroprotectant agent such as vitamin E in cisplatin- (CP-) induced nephrotoxicity has not been documented yet. Methods. One group from each gender of Wistar rats received a single dose of CP (7 mg/kg; i.p) and was treated with vitamin E (1 g/kg/day) for 7 days, and they were compared with similar gender in the control group. Results. The serum levels of blood urea nitrogen (BUN) and creatinine (Cr) in male animals treated with CP was not different from the control group, but it was significantly different in the female rats (P<0.05). The CP-induced damage intensity in male kidney tissue was not significantly different between the CP-treated and control groups, but this was not the case in female, indicating that the tissue damage in female is significantly different from the control group (P<0.05). No significant difference in serum levels of magnesium (Mg), nitrite, malondialdehyde (MDA), and lactate dehydrogenase (LDH) was seen between the genders. Kidney weight and body weight changes were statistically significant in both genders (P<0.05). Significant difference was observed in uterus weight between the two groups of female (P<0.05). Conclusion. Vitamin E may prevent CP-induced nephrotoxicity in male, but possibly it has not such nephroprotectant effect in female.

This study aimed to explore the clinical value of electroencephalogram (EEG) monitoring and the use of silver nanoparticles to detect serum levels of Nesfatin-1, S100β and Neuron-specific enolase (NSE) in assessing the severity and prognosis of epilepsy. A total of 54 epilepsy patients treated at our hospital from June 2017 to June 2019 were selected as the epilepsy group, and 54 healthy subjects were selected as the control group. EEG and serum levels of Nesfatin-1, S100β, and NSE in epilepsy patients without seizure and within 1 hour of seizure were ascertained and compared. The Liverpool Seizure Severity Scale (LSSS) score was used to evaluate the severity of epilepsy in patients, and the correlation between EEG findings and serum Nesfatin-1, S100β , and NSE levels was analyzed. ROC analysis was also conducted on the levels of the three factors. The patients were followed up for 1 year, the mortality rate was calculated, and the levels of Nesfatin-1, S100β, and NSE in deceased and non-deceased patients were compared. There were 50 cases (92.6%) with EEG abnormalities in the epilepsy group and 31 cases (57.4%) with epileptic EEGs in the epileptic non-seizure group. There was a significant difference in the proportion of abnormal EEGs between the two groups of epilepsy patients (P <0.05); the biomarker (Nesfatin-1, S100β, and NSE) serum levels were higher in both the non-seizure group and epileptic group than the control group, and the levels in the seizure group were higher than those in the non-seizure group (P < 0.05); seizures in patients with epilepsy were positively correlated with EEG abnormalities and biomarker serum levels. There was, however, no significant correlation between EEG abnormalities and biomarker serum levels. ROC analysis of epilepsy patients and their serum levels of Nesfatin-1, S100β and NSE showed that the area under the curve corresponding to each index was 0.850, 0.881, and 0.868, respectively (P < 0.05). With regards to deceased patients, the proportion with an abnormal EEG was 100% (15/15), which was higher than 41.0% (16/39) of non-deceased patients. Serum levels of biomarkers were also significantly higher than those in non-deceased patients (P < 0.05). Changes in EEG and biomarker serum levels were closely related to the severity of epilepsy. The proportion of patients with abnormal EEGs during seizure periods was higher, and the expression of serum Nesfatin-1, S100β and NSE was also increased, which means they can be used as markers of epilepsy and have an impact on its prognosis

ABSTRACT Toilet training is an effort to train children to be able to control and urinate (BAK) and defecate (BAB). Toilet training is one of the main tasks of children at toddler age. Toilet training is one of the main tasks of children in toddler age which is very important to be done to create independence in children in controlling BAK and BAB and children know the parts of the body and their functions. Data in 2012 shows that ± 60% of parents do not teach toilet training to children from an early age. The aim of the study was to find out the effectiveness of toilet training education on maternal behavior and toilet skills in toddler age training (18-36 months). The study was conducted in July-August 2018. This type of quantitative research used the design of the Quasy pretest and posttest experiment with non-equivalent control group design. Samples were 36 mothers and 36 children with purposive sampling technique. Data analysis used Paired t test, Wilcoxon test, Man-Whitney test an Independent t test. The results showed that toilet training education through lecture methods, modules and maze games was more effective than toilet training education through lecture and leaflet methods on children's knowledge and abilities. Conversely, for the role of mothers in supervision there is no significant difference in effectiveness. Health education is recommended in health promotion programs to increase maternal knowledge, the role of mothers and the ability of toilet training children independently.

Objective: India is the second country after China having the highest population prevalence of diabetes. Several research studies investigating diabetes have been done, but not much work has been done on prediabetes. The purpose of this study was to investigate the effect of nutrition and lifestyle modification on prediabetic females. Methods: A total of 120 prediabetic females from Ludhiana city were divided into 2 matched groups: control group (n = 60) and experimental group (n = 60). Impact of nutrition intervention for dietary and lifestyle modification (for 3 months) was assessed on the anthropometric, dietary, biochemical parameters, and diabetes risk score of the experimental group and control group (no intervention). Results: All the selected 120 subjects completed the study (experimental group = 60; control group = 60). There was significant difference in the changes between the 2 groups throughout the study. The fasting blood glucose and glycated hemoglobin A1c levels of the experimental group subjects reduced significantly ( P ≤ .01). However, no change was observed among the control group subjects. The lipid profile of the experimental group showed a significant improvement ( P ≤ .01). Conclusion: Nutrition counselling of the prediabetics regarding dietary and lifestyle modification is recommended so as to improve their metabolic control, thus preventing them from being diabetics.

Abstract Background Neuromyelitis optica spectrum disorder (NMOSD) is associated with inflammatory mediators that may also trigger downstream signaling pathways leading to reduce insulin sensitivity. Methods We aimed to determine the risk association of hyperinsulinemia in NMOSD patients with seropositive AQP4-IgG and the serum levels of interleukin (IL)-6 and IL-17A compared with the control group. Serum levels of metabolic (Insulin, Fasting Blood Sugar (FBS), lipid profile) and inflammatory (IL-6 and IL-17) markers were assessed in 56 NMOSD patients and 100 controls. Results Hyperinsulinemia was more prevalent in NMOSD patients independent of age, sex and body mass index (BMI) (48.2% vs. 26%, p = 0.005) compared to control group. After adjusting age, sex and BMI, there was significant association between lower insulin sensitivity (IS) and NMOSD risk (95% CI: Beta = 0.73, 0.62 to 0.86, p = 0.0001). Circulating levels of IL-6 and IL-17 were higher in NMOSD patients, and only IL-6 had an effect modifier for the association between lower insulin sensitivity and NMOSD risk. Conclusions Our data suggests that inflammatory pathogenesis of NMOSD leads to hyperinsulinemia and increases the risk of insulin resistance.
