Diagnosis and Treatment of Paraneoplastic Neurologic Syndromes.

Paraneoplastic antibody syndromes result from the anti-tumor antibody response against normal antigens ectopically expressed by tumor cells. Although this antibody response plays an important role in helping clear a nascent or established tumor, the engagement of antigens expressed in healthy tissues can lead to complex clinical syndromes with challenging diagnosis and management. The majority of known paraneoplastic antibody syndromes have been found to affect the central and peripheral nervous system. The present review provides an update on the pathophysiology of paraneoplastic neurologic s

Effects of Physical Exercise Intervention on Psychological and Physical Fitness in Lymphoma Patients.

Background and objectives: Lymphoma patients experience a psychological and physiological decline that could be reversed by exercise. However, little is known about the effects of the exercise on psychological and physical fitness variables. Therefore, the purpose of this longitudinal study was to assess self-efficacy, fatigue and physical fitness before and after an eight-week exercise intervention. Materials and Methods: Thirty-six participants (54.4 ± 19.1 years) performed a supervised exercise program (~60 min, 2d·wk-1). Each session included a combined progressive training of cardiorespir

The Role of Intravesicular Proteins and the Protein Corona of Extracellular Vesicles in the Development of Drug-Induced Polyneuropathy.

Extracellular vesicles (EVs) as membrane structures of cellular origin participating in intercellular communication are involved in the molecular mechanisms of the development of various variants of polyneuropathy. Taking into account the increasing role of the protein corona of EVs and protein-protein interactions on the surface of EVs in the pathogenesis of various diseases, we focused our attention in this review on the role of intravesicular proteins and the protein corona of EVs in the development of chemotherapy-induced polyneuropathy (CIPN). It has been shown that EVs are effectively in

Characteristics associated with decrements in objective measures of physical function in older patients with cancer during chemotherapy.

PurposeStudy purposes were to evaluate for inter-individual variability in the trajectories of three objective measures of physical function (PF) in older patients receiving chemotherapy (n = 112) and determine which characteristics were associated with worse PF.MethodsBalance, gait speed, and chair-stand test were evaluated at initiation and 1, 3, 6, 9, and 12 months following chemotherapy. Hierarchical linear modeling was used to assess inter-individual variability in the trajectories of the three tests. Demographic, clinical, and symptom characteristics, and levels of cognitive function ass

Chronic dysimmune neuropathies: Beyond chronic demyelinating polyradiculoneuropathy.

The spectrum of chronic dysimmune neuropathies has widened well beyond chronic demyelinating polyradiculoneuropathy (CIDP). Pure motor (multifocal motor neuropathy), sensorimotor with asymmetrical involvement (multifocal acquired demylinating sensory and motor neuropathy), exclusively distal sensory (distal acquired demyelinating sensory neuropathy) and very proximal sensory (chronic immune sensory polyradiculopathy) constitute the variants of CIDP. Correct diagnosis of these entities is of importance in terms of initiation of appropriate therapy as well as prognostication of these patients. T

Neuromuscular electrical stimulation for physical function maintenance during hematopoietic stem cell transplantation: Study protocol.

Hematopoietic stem cell transplantation is a common life-saving treatment for hematologic malignancies, though can lead to long-term functional impairment, fatigue, muscle atrophy, with decreased quality of life. Although traditional exercise has helped reduce these effects, it is inconsistently recommended and infrequently maintained, and most patients remain sedentary during and after treatment. There is need for alternative rehabilitation strategies, like neuromuscular electrical stimulation, that may be more amenable to the capabilities of hematopoietic stem cell transplant recipients. Pat

Bortezomib in the management of multiple myeloma.

Multiple myeloma (MM) is a B-cell malignancy characterized by clonal expansion of plasma cells within the bone marrow, the presence of a serum and/or urine monoclonal protein, lytic bone lesions, and anemia. On a cellular level, the disease is characterized by complex interactions between tumor cells and the surrounding bone marrow microenvironment. Understanding of the relationship between malignant plasma cells and the microenvironment has sparked ongoing efforts to develop targeted therapeutic agents for treatment of this disease. The successful development of the first-in-class small-molec

The Role of Nucleotide Excision Repair in Cisplatin-Induced Peripheral Neuropathy: Mechanism, Prevention, and Treatment.

Platinum-based chemotherapy-induced peripheral neuropathy (CIPN) is one of the most common dose-limiting effects of cancer treatment and results in dose reduction and discontinuation of life-saving chemotherapy. Its debilitating effects are often permanent and lead to lifelong impairment of quality of life in cancer patients. While the mechanisms underlying the toxicity are not yet fully defined, dorsal root ganglia sensory neurons play an integral role in symptom development. DNA-platinum adducts accumulate in these cells and inhibit normal cellular function. Nucleotide excision repair (NER)

Bortezomib-induced gastrointestinal dysfunction, peripheral neuropathy and neuroimmune signalling are influenced by the gut microbiota in mice.

BACKGROUND: Peripheral neuropathy and gastrointestinal dysfunction are frequent, debilitating side effects of the neurotoxic myeloma drug bortezomib that reduce quality of life and adherence to optimal therapy. Therapeutic strategies to manage these complications are limited. Here, we have developed a mouse model of bortezomib side effects to investigate the role of the gut microbiota in their development. METHODS: C57BL/6 specific pathogen-free (SPF), germ-free (GF) and ex-GF mice (colonised with healthy gut microbiota via faecal microbiota transplantation [FMT]) were treated with bortezomib
