Relationship between BODE index, quality of life and inflammatory cytokines in COPD patients

BACKGROUND AND AIMS: Recently a multidimensional grading system based on the body mass index (B), degree of airflow obstruction (O), dyspnea (D) and exercise capacity (E) - the BODE index - has begun to be used increasingly for the evaluation of chronic obstructive pulmonary disease (COPD) patients. The aim of our study was to investigate the relationship between the BODE index and disease duration, annual exacerbation and hospitalization rates, health related quality of life and systemic inflammatory markers like C-reactive protein (CRP), tumor necrosis factor (TNF)-α and interleukin (IL)-8. MATERIALS AND METHODS: In 88 stable COPD patients we evaluated the body-mass index, pulmonary function tests, Modified Medical Research Council dyspnea scale and six-minute walk test (6 MWT). BODE scores were determined. Disease duration, number of exacerbations and hospitalization in the previous year were recorded. We also performed arterial blood gases analysis, administered the St. George's Respiratory Questionnaire (SGRQ) and measured serum levels of CRP, TNF-α, IL-8. RESULTS: According to BODE score 52% of patients were BODE 1, 21% BODE 2, 15% BODE 3 and 12% were BODE 4. There was a significant relationship between BODE index and COPD stage as classified according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) (p < 0.001). Correlations between BODE score and disease duration (p = 0.011), number of exacerbations (p < 0.001) and hospitalizations (p < 0.001) in the last year were also observed. SGRQ symptom, activity, emotion scores and total scores were found to be significantly correlated to BODE (p < 0.001). Serum CRP levels and BODE were also correlated (p = 0.014); however, no correlation was found between serum levels of TNF-α and IL-8 and BODE. CONCLUSIONS: As the BODE index shows a strong correlation with various prognostic and follow up parameters of COPD and systemic inflammation, its use should be considered for the evaluation of COPD patients

Iroquois Complex Genes Induce Co-Expression of rhodopsins in Drosophila

The Drosophila eye is a mosaic that results from the stochastic distribution of two ommatidial subtypes. Pale and yellow ommatidia can be distinguished by the expression of distinct rhodopsins and other pigments in their inner photoreceptors (R7 and R8), which are implicated in color vision. The pale subtype contains ultraviolet (UV)-absorbing Rh3 in R7 and blue-absorbing Rh5 in R8. The yellow subtype contains UV-absorbing Rh4 in R7 and green-absorbing Rh6 in R8. The exclusive expression of one rhodopsin per photoreceptor is a widespread phenomenon, although exceptions exist. The mechanisms leading to the exclusive expression or to co-expression of sensory receptors are currently not known. We describe a new class of ommatidia that co-express rh3 and rh4 in R7, but maintain normal exclusion between rh5 and rh6 in R8. These ommatidia, which are localized in the dorsal eye, result from the expansion of rh3 into the yellow-R7 subtype. Genes from the Iroquois Complex (Iro-C) are necessary and sufficient to induce co-expression in yR7. Iro-C genes allow photoreceptors to break the “one receptor–one neuron” rule, leading to a novel subtype of broad-spectrum UV- and green-sensitive ommatidia

Information Needs of Patients with Meningiomas

WOS: 000293172800019PubMed ID: 21545209The aim of this descriptive, cross-sectional study was to determine information requirements of patients with typical meningiomas after surgery. The study sample consisted of 20 patients who underwent surgery for brain tumours in neurosurgery clinics of a university hospital. Permission to conduct research was obtained from all patients and from the hospital. Before the surgery, a booklet was given to patients for training. Patients were followed up one, three, six and 12 months later by the phone after the surgery and asked to report their problems. All questions were recorded and answered. Data were collected by the socio-demographic, patient symptom and health status questionnaire. Descriptive data were analyzed using percentage and arithmetic averages. Comparative statistics were evaluated using chi-square. Patients wanted information about diet, physical therapy and rehabilitation, quick thinking difficulties, fasting, headache, irritability, personality change, fatigue, driving, deep vein thrombosis during the follow up. There was a significant difference between their health status and fear of seizures and recurrent tumor, forgetfulness, lack of concentration (p<0.05). Although they received health education and booklet, patients needed more information during the 12 months after surgery. Therefore it suggested that monitoring the patient's needs is necessary

Approach to the mechanism of action of hydroxychloroquine on SARS-CoV-2: a molecular docking study

We aimed to analyze the interactions of both hydroxychloroquine and chloroquine with SARS-CoV-2 and identify their possible role for the prevention/treatment of COVID-19 by molecular docking studies. Protein crystal structures of SARS-CoV-2 and ACE2, the compounds hydroxychloroquine and chloroquine, and other ligand structures were minimized by OPLS3 force field. Glide Standard Precision and Extra Precision docking are performed and MM-GBSA values are calculated. Molecular docking studies showed that hydroxychloroquine and chloroquine do not interact with SARS-CoV-2 proteins, but bind to the amino acids ASP350, ASP382, ALA348, PHE40 and PHE390 on the ACE2 allosteric site rather than the ACE2 active site. Our results showed that neither hydroxychloroquine and chloroquine bind to the active site of ACE2. However, both molecules prevent the binding of SARS-CoV-2 spike protein to ACE2 by interacting with the allosteric site. This result can help ACE2 inhibitor drug development studies to prevent viruses entering the cell by attaching spike protein to ACE2. Communicated by Ramaswamy H. Sarm

Physical fitness, physical activity, psychosocial status and quality of life of adolescent siblings of neurologically disabled children

WOS: 000454454100003Background: This study aims to compare physical fitness, physical activity, the psychosocial state and the quality of life of adolescents who have disabled siblings with the adolescents who have healthy siblings. Material and methods: 100 adolescents were involved. The Body Mass Index, flexibility, muscular strength and endurance were measured to determine physical fitness. The FELS Physical Activity Questionnaire, the Depression Scale(CES-DC) and the 87-item Child Health Questionnaire(CHQ) were used to determine the level of their physical activity, depression status and the level of quality of life. Results: Only Vertical Jumping level among physical fitness parameters was found to be different between the groups (p 0.05). Conclusions: A physically disabled child negatively affects the physical activity level and psychology of healthy siblings rather than their physical fitness

FlyOde - a platform for community curation and interactive visualization of dynamic gene regulatory networks in Drosophila eye development [version 1; referees: 2 approved]

Motivation: Understanding the regulatory mechanisms governing eye development of the model organism Drosophila melanogaster (D. m.) requires structured knowledge of the involved genes and proteins, their interactions, and dynamic expression patterns. Especially the latter information is however to a large extent scattered throughout the literature. Results: FlyOde is an online platform for the systematic assembly of data on D. m. eye development. It consists of data on eye development obtained from the literature, and a web interface for users to interactively display these data as a gene regulatory network. Our manual curation process provides high standard structured data, following a specifically designed ontology. Visualization of gene interactions provides an overview of network topology, and filtering according to user-defined expression patterns makes it a versatile tool for daily tasks, as demonstrated by usage examples. Users are encouraged to submit additional data via a simple online form

Investigation of insulin-like growth factor-1 (IGF-1), p53, and wilms’ tumor 1 (WT1) expression levels in the colon polyp subtypes in colon cancer

PubMed ID: 31341157Background: There is no study in the literature investigating the expression levels of WT1, p53, and IGF-1 in colon polyp subtypes. In this study, we aimed to investigate the expression levels of IGF-1, p53, and WT1 in colon polyp subtypes and to determine whether expression levels are correlated with each other. Material/Methods: Tissue specimens were obtained from 105 patients (80 men, 25 women; age range, 30–91 years) who underwent surgical resection for colorectal cancer (CRC) at Ordu University School of Medicine, Department of Pathology between January 2015 and 2017. Parameters such as age, sex, region of origin, and pathological diagnosis type were determined. The preparations were immunohistochemically stained with corresponding markers. Results: The results of the study showed that there was a statistically significant relationship between WT1 expression (negative–positive) in polyps and the place where the sample was taken (P=0.011). There is a positive relationship between P53 staining score (0–3) and positive frequency of IGF-1 (60.9–85.7%). There was a statistically significant change in P53 scores and location (P=0.006, p=0.015, respectively). As the P53 score of the polyps increased (0 to 3), the rate of adenomatous (34.8–78.4%) increased, so a positive relationship was found. WT1 and IGF-1 gene expression was associated with tumor location, p53 staining score, and sex. Conclusions: WT1 and IGF-1 are appropriate markers for CRC, and WT1 expression in CRC primary tumors especially could be a novel independent marker for prognosis and tumor progression. © Med Sci Monit.Firat University Scientific Research Projects Management Unit, FÃœBAP: AP-1727Ali Aslan, e-mail: [email protected] This study was supported by Ordu University Scientific Research Project Unit (Project No: AP-1727
