Despair Beyond Repair? Severity of Hopelessness in Depressed Psychiatric Inpatients
Abstract:
Depression is related to suicidal ideation, attempts, and completion. However, depression fails to provide any specific identification for suicide risk. Hopelessness has been found to provide a more accurate estimate of suicide risk than seen in depression severity, and hopelessness can serve as a useful predictor of eventual death by suicide. The present study was designed to examine various levels of hopelessness and their association with other symptoms experienced by depressed psychiatric inpatients. 150 adult psychiatric inpatients were evaluated using a structured diagnostic interview and several standardized self-report questionnaires. All patients met criteria for a depressive diagnosis at ...
Knowledge, Perception And Practice Of Preventive Lifestyle Against HIV/AIDS Among Students Of A Tertiary Educational Institution In South Eastern Nigeria.
Abstract:
HIV/AIDS has become a global scourge affecting mainly young people. Sexual behavior change remains the most effective way of preventing further spread. The aim of this study is to assess the knowledge, perception and practice of safe lifestyles towards prevention of HIV infection among students of a tertiary educational institution in Abakaliki, south eastern, Nigeria. A cross sectional descriptive study was carried out, and participants were selected using multistage sampling technique. Data was collected using a pretested, self administered questionnaire and analyzed using SPSS software, version 20. Three hundred and eighty seven participants were recruited for the study, including 199 (51.4%) males and 188 (48.6%) females. Mean age of participants was 23.6 ±2years. All (100%) of the participants were aware of the existence of HIV/AIDS, with the commonest source of information being electronic media (81.1%). Their knowledge of the routes of transmission and m...
Comparison of Two Analytical Methods used for the Measurement of Total Antioxidant Status
Abstract:
Antioxidants play an important role in maintenance of human health and prevention of disease. Effective supplementation of antioxidants requires laboratory monitoring of antioxidant status. An understanding of the methods used to determine the TAS helps in better interpretation of values obtained using a particular method and also to select a suitable method. Forty subjects including 25 healthy volunteers and 15 patients diagnosed with rheumatoid arthritis were studied. All samples were analysed for TAS using Ferric reducing ability of plasma (FRAP) method and Trolox equivalent antioxidant capacity (TEAC) assay. Mean TAS values obtained by TEAC method were higher than those obtained by ...
Age Variation in Bitter Taste Perception in Relation to the Tas2r38 Taste Receptor Phenotype
Abstract:
Taste sensitivity is an important determinant of food choice and differs between children and adults. This difference is probably due to several factors that constitute an individual’s phenotype. The aim of this study was to explore taste perception in relation to the TAS2R38 and CAVI (gustin) genotypes in age classes from infancy to adulthood in a Mediterranean population. In this cross-sectional study we evaluated the TAS2R38 and gustin genotypes and administered a standardized PROP taste test in 705 individuals (435 adults, 270 children); the sample included 224 mother-child dyads. We also explored the acceptance and consumption of bitter and non-bitter vegetables. Sensitivity to bitterness was s...
Evaluating Circadian Oscillators in Cancer Stem Cells
Abstract:
Cancer is influenced by the ability of cells to maintain circadian rhythms in molecular and metabolic processes. Disturbance of the underlying circadian timing mechanism in circadian clock cells leads to a higher frequency and more rapid progression of cancer. Cancer stem cells with properties of embryonic and somatic stem cells have been implicated as tumor initiators in several types of cancers. Although tumors are reported to have disorganized circadian rhythms, evidence of in vitro circadian rhythms in cancer stem cells of gliomas was recently presented. The possibility and consequences of circadian clocks functioning in cancer stem cells within tumors is examined, and the possible benefits to these cells from circadian timing is discussed in relation to cancer treatments.
One-Third of Patients With Type 2 Diabetes Mellitus Do Not Have Coronary Artery Calcification
Abstract:
Measuring coronary artery calcification (CAC) enables to optimize cardiovascular risk-stratification also in patients with type 2 diabetes mellitus (T2D), however the prevalence of CAC in randomly selected patients with T2D is uncertain. For this purpose we set out to examine and compare the occurrence of CAC in unselected T2D patients. A randomly selected cohort of 1825 individuals, men and women, either 50 or 60 years old, were invited to the screening study. Traditional risk factors were obtained and a non-contrast CT-scan was performed to assess the CAC score. A total of 1211 individuals participated, of whom 54 (4%) had T2D while 1157 (96%) were without diabetes. CAC was present in 62% of the patien...
Barriers to Physical Activity and Healthy Eating in Children as Perceived by Low-Income Parents: A Case Study
Abstract:
During the past three decades the prevalence of childhood obesity has steadily increased in the United States. Causes of childhood obesity are complex and include numerous individual and environmental factors. The purpose of this study was to determine parent perceptions on the social-ecological barriers (community, school, and family) to physical activity and healthy eating, perceived specific to their children. Self-reported data gathered from a 50-item questionnaire and six focus groups were conducted with parents (
Overexpression of Prostate Apoptosis Response Protein-4 In Colon Cancer Cells Can Inhibit Metastasis by Upregulating E-cadherin Expression
Abstract:
Colon cancer has a five-year survival of 64.7%, and about 50,000 people are expected to die from colon cancer this year. Patients with metastatic colorectal cancer have a significantly worse prognosis, a 12.9% five-year survival. This emphasizes the need for strategies to inhibit the growth and metastases of colorectal cancer. Prostate apoptosis response protein 4 (Par-4) is a pro-apoptotic protein that has been shown to mediate apoptosis in response to stimuli, such as chemotherapeutics and radiation. Recombinant Par-4 protein has been shown to reduce the occurrence of Lewis lung carcinoma metastases in-vivo; however, the mechanism by which Par-4 can inhibit metastasis has not been elucidated. In this study, human colon cancer cell lines - SW480 and SW620 - were transfected with Par-4 plasmid or anti-Par-4 shRNA, and the effect on metastasis was examined. Par-4 overexpression inhibited cell migration and invasion, while Par-4 knockdown promoted it. Moreover, the...
Why Music in Neurology?
Abstract:
In the last years we could find many uses of music in different clinical settings, also in the field of neurology. In this field empirical results, but also scientific studies, showed the efficacy of music interventions on psychological, cognitive and motor aspects. This is consistent with strong effects of music on brain areas. Music can stimulate and modulate/regulate cognitive functions, behaviors, movements and emotions. Music plays an important role also from a psychological point of view, increasing motivation and promoting relationships and communication. Literature has showed how music interventions can improve behavioral, cognitive, motor, psychological, relational and emotional outcomes in different neurological pathologies. Significant results are present in particular in dementia, stroke and Parkinson's disease. We can find also minor results and qualitative research approaches in multiple sclerosis and in other brain injury such as vegetative and mini...
Subjective and Objective Actigraphic Sleep Monitoring and Psychopathology in a Clinical Sample of Patients with Night Eating Syndrome, with and Without Binge Eating Behaviors
Abstract:
Night Eating Syndrome (NES) is a phenomenon combining aspects of both sleeping disorders and Eating Disorders (EDs). To the best of our knowledge, few studies to date have examined NES among patients with EDs. None examined ED patients with and without NES in clinical settings by comparing their sleep disturbances using the new NES diagnostic criteria The sample included 71 women, ages 19-62, referred for assessment to a hospital Eating Disorders Clinic. Measures included self-report questionnaires, psychiatric evaluation and actigraph recording for one week. Participants were divi...
