Mechanistic insights into the pathogenesis of neurodegenerative diseases: towards the development of effective therapy.

Neurodegeneration is a prevalent and one of the emerging reasons for morbidity, mortality, and cognitive impairment in aging. Dementia is one of such conditions of neurodegeneration, partially manageable, irreversible, and worsens over time. This review is focused on biological and psychosocial risk factors associated with Alzheimer's and Parkinson's diseases, highlighting the value of cognitive decline. We further emphasized on current therapeutic strategies from pharmacological and non-pharmacological perspectives focusing on their effects on cognitive impairment, protein aggregation, tau pathology, and improving the quality of life. Deeper mechanistic insights into the multifactorial neurodegeneration could offer the design and development of promising diagnostic and therapeutic strategies.

Hope, meaning in life and religious/spiritual struggle predicts the quality of life in cancer patients with early and advanced malignancy: a structural equation modeling approach.

Purpose: This study examined hope, meaning in life (MIL), and religious/spiritual struggle (RSS) as predictors of the quality of life (QOL) in cancer patients. We hypothesized a positive association of QOL with hope and MIL, whereas a negative association with RSS. The stage of cancer was hypothesized as a moderator variable between QOL and hope. Hope and MIL were assumed as positive predictors and RSS as negative predictor of QOL. Methods: Data stem from the cross-sectional survey study of 300 cancer patients (Mean age = 50.97 ± 13.50 SD). Herth Hope Index, Meaning in Life Scale, Religious Spiritual Struggle Scale and WHO-QOL-BRIEF were used. The correlation coefficient and partial least square structural equation modeling approach (PLS-SEM) were used for assessing the measurement model and the structural model. Results: As hypothesized, QOL was found positively associated with Hope and MIL, but negatively associated with RSS. The stage of cancer was hypothesized as a negative moderator. The three predictors significantly predicted QOL in cancer patients and explained 75.3% of the variance in QOL, and the overall model fit was adequate (SRMR = 0.075). Hope and MIL had a positive impact on QOL (ß = .356, p < 0.01; ß = .355 p < 0.01, respectively), whereas RSS had a negative impact (ß = -.102, p < .05). The Stage of cancer did not moderate the path coefficient between the hope and QOL to a significant degree (ß = .097, p > 0.01). Conclusion: In cancer patients, hope and MIL are facilitators of QOL. Addressing religious and spiritual concerns and struggles is critical to overall QOL improvement.

Brain-Derived Neurotrophic Factor: A Connecting Link Between Nutrition, Lifestyle, and Alzheimer's Disease.

Brain-derived neurotrophic factor (BDNF) involving tropomyosin kinase B and low affinity p75 neurotropin receptors is the most abundant and researched neurotropins in mammal's brain. It is one of the potential targets for therapeutics in Alzheimer's disease (AD) owing to its key role in synaptic plasticity. Low levels of BDNF are implicated in the pathophysiology of neurological diseases including AD. However, a healthy lifestyle, exercise, and dietary modifications are shown to positively influence insulin regulation in the brain, reduce inflammation, and up-regulate the levels of BDNF, and are thus expected to have roles in AD. In this review, the relationship between BDNF, mental health, and AD is discussed. Insights into the interrelationships between nutrition, lifestyle, and environment with BDNF and possible roles in AD are also provided in the review. The review sheds light on the possible new therapeutic targets in neurodegenerative diseases.

An interpretive phenomenological analysis of hope in cancer patients: A qualitative study.

BACKGROUND: In positive psychology, increased recognition of the phenomenon of hope among people suffering from cancer, along with alleviating their negative mental states like anxiety, depression, and fear of death is evident and promising. The aim of the study was to explore the lived experience of hope in cancer patients. MATERIALS: Qualitative phenomenological research approach was used. A semi-structured in-depth interview with open-ended questions was administered to explore the patient's hope related experiences during the journey of cancer. A purposive sampling technique was used to select a total of 10 participants for the study. The size of the sample was decided on the basis of literature for the interpretive phenomenological study. RESULTS: Results revealed five major common themes related to hope during illness: (1) survival expectation; (2) will to live; (3) prognostic clarification; (4) positivity of health providers; and (5) recovery of other patients: A source of hopefulness. CONCLUSION: The lived experiences of cancer patients shows that hope is the positive expectation of survival, which is a source of motivation during their journey of illness. It also denotes goal setting behaviour. Thus, hope is the "will to live" which is related to social support, positive communication with healthcare providers, and recovery of fellow patients.
