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...

Background: Medical staff often overlook or underestimate the presence or severity of cognitive dysfunction. The purpose of this study was to clarify the frequency, clinical indicators and predictors of cognitive dysfunction among newly diagnosed older patients with hematologic malignancy receiving first-line chemotherapy. Methods: Patients aged 65 years or over with a primary diagnosis of malignant lymphoma or multiple myeloma were consecutively recruited. Cognitive dysfunction was evaluated using the Mini-Mental State Examination (MMSE) twice: before starting chemotherapy (T1) and 1 month later (T2)...

BACKGROUND: Biomarkers can be used as prognostic, predictive, or monitoring indicators of an associated outcome. The purpose of this review was to provide a comprehensive summary of the research examining the use of biomarkers as surrogate end points for clinical outcomes in family caregivers for cancer patients, identify gaps, and make recommendations for future research. METHODS: A scoping review, a process of mapping the existing literature, was conducted. Studies comparing biomarkers across caregivers and controls and/or examining relationships between biomarkers and psychological health were reviewed...

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...

BACKGROUND: High levels of fatigue have been documented in ovarian cancer patients. However, increased levels of fatigue are positively associated with a high risk of sleep disturbance and depression. OBJECTIVE: To investigate the feasibility of a nurse-led home-based exercise and cognitive behavioral therapy (E&CBT) for ovarian cancer adults with cancer-related fatigue on outcomes of fatigue, plus other secondary outcomes (sleep disturbance and depression), either during or after completion of primary cancer treatment...

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...

Cognitive dysfunction by chemotherapy compromises the quality of life in cancer patients. Tea polyphenols are known chemopreventive agents. The present study was designed to evaluate the neuroprotective potential of (+) catechin hydrate (catechin), a tea polyphenol, in IMR-32 neuroblastoma cells in vitro and alleviation of episodic memory deficit in Wistar rats in vivo against a widely used chemotherapeutic agent, Doxorubicin (DOX). In vitro, neuroprotective studies were assessed in undifferentiated IMR-32 cells using percentage viability and in differentiated cells by neurite length...

BACKGROUND: Fifteen to twenty percent of patients with locally advanced rectal cancer have a clinical complete response after chemoradiation therapy. These patients can be offered nonoperative organ-preserving treatment, the so-called watch-and-wait policy. The main goal of this watch-and-wait policy is an anticipated improved quality of life and functional outcome in comparison with a total mesorectal excision, while maintaining a good oncological outcome. OBJECTIVE: The aim of this study was to compare the quality of life of watch-and-wait patients with a matched-controlled group of patients who underwent chemoradiation and surgery (total mesorectal excision group)...

AIM: To translate the Xerostomia Quality-of-Life Scale (XeQoLS) into Italian language (XeQoLS-IT). Xerostomia is the most relevant acute and late toxicity in patients with head and neck cancer treated with radiotherapy (RT). Patient-reported outcome (PRO) instruments are subjective report on patient perception of health status. The XeQoLS consists of 15 items and measures the impact of salivary gland dysfunction and xerostomia on the four major domains of oral health-related QoL. METHODS: The XeQoLS-IT was created through a linguistic validation multi-step process: forward translation (TF), backward translation (TB) and administration of the questionnaire to 35 Italian patients with head and neck cancer...

Usually limbic encephalitis (LE) is a paraneoplastic neurologic syndrome. LE symptoms can precede cancer even by a few years. Almost 50% of LE cases are connected with small cell lung carcinoma. Testis and breast cancers, granulomatous disease, thymoma, and teratomas are also often connected with LE. Other cases have infectious and autoimmunological aetiology. In LE limbic system dysfunction is observed, and it is accompanied by cerebellum and brain stem abnormalities as well as polyneuropathy. Paraneoplastic limbic encephalitis is sometimes a part of larger syndrome in which brain stem and spinal cord are involved in an inflammatory process called paraneoplastic encephalomyelitis...

Małgorzata Gietka-Czernel
The incidence of most thyroid diseases: hypothyroidism, nodular goitre, and cancer is highest among postmenopausal and elderly women. The diagnosis of thyroid dysfunction in this group of patients is difficult because the symptoms can be nonspecific or common with menopausal and ageing complaints. In the interpretation of thyroid function tests the physiological changes in secretion and metabolism of thyrotropin (TSH) and thyroid hormones must be considered, as well as the influence of comorbidities. Unrecognised thyroid dysfunction leads to increased: cardiovascular risk, bone fractures, cognitive impairment, depression, and mortality...

Fear of progression (FoP) is an appropriate, rational response to the real threat of cancer and its treatments. However, patients experiencing elevated, dysfunctional levels of FoP often feel severely distressed and are in need of treatment. We previously conducted a (partly-)randomized controlled study with cancer patients undergoing in-patient rehabilitation and showed that a brief, four-session cognitive-behavioral group therapy significantly reduced dysfunctional FoP. In this report, we describe the adaption of the cognitive-behavioral group therapy program for use with cancer out-patients...

Although development of cognitive decline in cancer patients who receive chemotherapy is common, the underlying mechanism(s) remains to be identified. As abnormalities in adult hippocampal neurogenesis may serve as substrate for cognitive dysfunction, the present study examines the effect of cyclophosphamide (CPP), a widely prescribed chemotherapeutic agent, on dendritic development of adult-born hippocampal granule cells in the rat. CPP was intraperitoneally injected into male Sprague-Dawley rats once a week for four consecutive weeks...

BACKGROUND: The survivorship needs of patients living with chronic cancer (CC) and their use of survivorship care plans (SCPs) have been overlooked and underappreciated. METHODS: A convenience sample of 39,088 SCPs completed for cancer survivors with an Internet-based SCP tool was examined; it included 5847 CC survivors (15%; CC was defined as chronic leukemia and/or recurrent/metastatic cancer of another nature). Patient-reported treatment effects and follow-up care patterns were compared between CC survivors and survivors treated with curative intent (CI)...

Improvements in diagnosis and treatments explain the notable increase in patients chronically affected or recovering from cancer. This is a fragile population, who is physically, psychologically and socially affected by the consequences of the disease and the associated treatments. In addition to detecting a possible relapse, oncologists and primary care physicians have to deal with a variety of issues like psychological distress, sexual dysfunction, cardiotoxicity, cognitive impairment, fatigue and, in some cases, a second primary cancer...
