PURPOSE: Cancer-related fatigue (CRF) and chemotherapy-related cognitive impairment (CRCI) are reported to be associated with mitochondrial dysfunction. Hence, mitochondrial DNA (mtDNA) content, a biomarker of mitochondrial dysfunction, is hypothesized to correlate with the onset of CRF and CRCI. This study aims to evaluate the association between peripheral blood mtDNA content reduction and severity of CRF and CRCI in patients receiving chemotherapy. METHODS: This was a prospective cohort study...

Sleep, a mysterious behavior, has recently been recognized as a crucial factor for health and longevity. The daily sleep/wake cycle provides the basis of biorhythms controlling whole-body homeostasis and homeodynamics; therefore, disruption of sleep causes several physical and psychological disorders, including cardiovascular disease, obesity, diabetes, cancer, anxiety, depression, and cognitive dysfunction. However, the mechanism linking sleep disturbances and sleep-related disorders remains unknown. Orexin (also known as hypocretin) is a neuropeptide produced in the hypothalamus...

BACKGROUND: Increasing numbers of elderly patients are undergoing long-term dialysis. However, the role of dialysis in survival and quality of life is unclear, and poor outcomes may be associated with comorbidities rather than with age only. The initiation of unplanned dialysis in elderly patients with chronic kidney disease (CKD) has been reported to be associated with poor survival. We evaluated patient and practice factors associated with poor survival. METHODS: We performed a retrospective analysis of 90 consecutive elderly patients (≥75 years) with CKD initiated on long-term dialysis at our renal unit between October 2010 and February 2014...

Androgen deprivation therapy (ADT) is the mainstay of treatment of patients with relapsed or metastatic hormone-sensitive prostatic carcinoma. The dramatic reduction of serum testosterone levels induced by ADT produces multiple side effects as vasomotor flushing, sexual dysfunction, fatigue, impairment of cognitive function, reduced quality of sleep, gynecomastia and anemia, that are able to decrease health-related quality of life (QoL). In addition, hormonal therapy can interfere with bone metabolism and induce metabolic and cardiovascular complications...

A literature review was done using the Cognitive-Social Health Information Processing (C-SHIP) framework to identify how and why men diagnosed with prostate cancer choose active surveillance over other treatment options. Findings indicated men who choose active surveillance have a stronger preference for active or collaborative decision-making than those who choose other treatments. Men primarily choose active surveillance to avoid the side effects of incontinence and erectile dysfunction. This literature review informed the study by Bayliss, Duff, Strieker, and Walker (2016) and found physician recommendation to be the most influential factor when patients make a treatment decision...

An increasing number of patients are living with or surviving cancer due to improvements in detection and treatment. However, patients who survive cancer may experience functional disabilities that impact on health, quality of life and ability to work. For example, physical disorders may include fatigue, reduced muscle strength, cognitive dysfunction, paresthesia or nutrition problems, while mental symptoms may include anxiety, depression, fear of relapse or insomnia. Multidimensional oncological rehabilitation programs have been developed to address these disabilities and to help cancer patients and long-term survivors to reduce morbidity and to improve quality of life...

Doxorubicin, a commonly used anti-neoplastic agent, causes severe neurotoxicity. Doxorubicin promotes thinning of the brain cortex and accelerates brain aging, leading to cognitive impairment. Oxidative stress induced by doxorubicin contributes to cellular damage. In addition to mitochondria, peroxisomes also generate reactive oxygen species (ROS) and promote cell senescence. Here, we investigated if doxorubicin affects peroxisomal homeostasis in neurons. We demonstrate that the number of peroxisomes is increased in doxorubicin-treated neurons and in the brains of mice which underwent doxorubicin-based chemotherapy...

Development targets in anaesthetic pharmacology have evolved from minimizing harm caused by unwanted effects through an era in which rapid onset and offset of drug effect were prioritised. Today's anaesthetists have access to a library of effective drugs whose characteristics offer controllable hypnosis, analgesia and paralysis with manageable off-target effects. The availability of these agents at generic prices inhibits commercial interest and this is reflected in the limited number of current anaesthetic drug development projects...

Ursolic acid is a pentacyclic triterpenoid found in several plants. Despite its initial use as a pharmacologically inactive emulsifier in pharmaceutical, cosmetic and food industries, several biological activities have been reported for this compound so far, including anti-tumoural, anti-diabetic, cardioprotective and hepatoprotective properties. The biological effects of ursolic acid have been evaluated in vitro, in different cell types and against several toxic insults (i.e. 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine, amyloid-β peptides, kainic acid and others); in animal models of brain-related disorders (Alzheimer disease, Parkinson disease, depression, traumatic brain injury) and ageing; and in clinical studies with cancer patients and for muscle atrophy...

In cancer, epilepsy can be the manifestation of a primary brain tumour, metastatic disease, vascular or surgical complications, opportunistic infection or secondary to anti-tumour therapy. Seizures are frequently the first symptom of a brain tumour. The epilepsy is related to elevated extracellular glutamate stimulating NMDA- and AMPA-receptors and to the formation of D-2HG which resembles glutamate in IDH1 mutated gliomas. Epilepsy as presenting sign is associated with a longer survival in low- and high- grade gliomas, particularly with the IDH1 mutation...

OBJECTIVE: Breast cancer patients frequently complain of cognitive dysfunction during chemotherapy. Patients also report experiencing a cluster of sleep problems, fatigue and depressive symptoms during chemotherapy. We aimed to understand the complex dynamic interrelationships of depression, fatigue, and sleep to ultimately elucidate their role in cognitive performance and quality of life among breast cancer survivors undergoing chemotherapy treatment. METHODS: Our study sample comprised 74 newly diagnosed stage I-III breast cancer patients scheduled to receive chemotherapy, and followed them for one year...

Whole brain irradiation (WBI) has become an indispensible tool in the treatment of head and neck cancer, and it has greatly improved patient survival rate and total survival time. In addition, prophylactic cranial irradiation (PCI) has dramatically decreased the incidence of brain metastatic carcinoma. However, WBI may induce temporary functional deficits or even progressive, irreversible cognitive dysfunction that compromises the quality of life for survivors. Unfortunately, the exact molecular mechanisms for cognitive damage remain elusive, and no treatment or preventative measures are available for use in the clinic...

Patients with cancer are experiencing long-term survival following chemotherapy, but the treatment may also be associated with short and long-term toxicity, including the possibility of cognitive dysfunction. A literature overview indicated a significant association between chemotherapy and cognitive impairment but prospective longitudinal research is warranted to examine the degree and persisting nature of this decline. Although chemotherapeutic agents are unlikely to cross the blood-brain barrier, it has been alleged that the occurrence of neurotoxicity is linked to the pro-inflammatory cytokine pathways...
