Beyond brain deficits caused by strokes, the effectiveness of neurorehabilitation is strongly influenced by the baseline clinical features of stroke patients, including a patient’s current nutritional status. Malnutrition, either as a pre-stroke existing condition or occurring because of ischemic injury, predisposes patients to poor rehabilitation outcomes. On the other hand, a proper nutritional status compliant with the specific needs required by the process of brain recovery plays a key role in post-stroke rehabilitative outcome favoring neuroplasticity mechanisms. Oxidative stress and inflammation play a role in stroke-associated malnutrition, as well as in the cascade of ischemic events in the brain area, where ischemic damage leads to neuronal death and brain infarction, and, via cell-to-cell signaling, the alteration of neuroplasticity processes underlying functional recovery induced by multidisciplinary rehabilitative treatment. Nutrition strategies based on food components with oxidative and anti-inflammatory properties may help to reverse or stop malnutrition and may be a prerequisite for supporting the ability of neuronal plasticity to result in satisfactory rehabilitative outcome in stroke patients. To expand nutritional recommendations for functional rehabilitation recovery, studies considering the evolution of nutritional status changes in post-stroke patients over time are required. The assessment of nutritional status must be included as a routine tool in rehabilitation settings for the integrated care of stroke-patients.
Objective: The aim was to verify whether oxidative stress could represent a common key factor of benign prostatic hyperplasia (BPH) and prostate cancer (PCa). Subjects and Methods: 15 patients affected by BPH, 15 with PCa and 15 controls were enrolled. Blood samples were withdrawn systemically and locally during radical retropubic prostatectomy in patients with PCa and during transvesical retropubic adenomectomy in patients diagnosed with BPH. Plasma oxidized low-density lipoprotein, peroxides, and total equivalent antioxidant capacity (TEAC) including plasma superoxide dismutase (SOD) determination were analyzed as oxidative markers. Results: With respect to the control group, high plasma peroxides and decreased TEAC levels were measured in patients affected by both PCa and BPH. Plasma peroxides were significantly higher in patients with PCa with respect to BPH. A positive correlation was found between peroxides and TEAC values in samples withdrawn locally in patients affected by PCa. An inverse correlation between peroxides and TEAC was observed in patients with BPH. No statistically significant modifications were observed as concerns SOD activity and LDL oxidability. Conclusions: Our findings confirm a significant unbalance of redox status in patients affected by BPH and PCa, and suggest a potential involvement of oxidative stress as a determinant in the pathogenesis of these diseases.
