Preoperative prognostic nutritional index (PNI) has been widely demonstrated to predict survival of patients with malignant tumors. Its utility in predicting outcomes in patients with high-grade gliomas (HGG) remains undefined. A retrospective study of 188 HGG patients was conducted. An optimal PNI cut-off value was applied to stratify patients into high PNI (≥52.55, n = 78) and low PNI (<52.55, n = 110) groups. Univariate and multivariate analysis was performed to identify prognostic factors associated with overall survival (OS) and progression free survival (PFS)...

BACKGROUND: Prostate cancer has a propensity to invade and grow along nerves, a phenomenon called perineural invasion (PNI). Recent studies suggest that presence of PNI in prostate cancer has been associated with cancer aggressiveness. METHODS: We investigated the association between PNI and lethal prostate cancer in untreated and treated prostate cancer cohorts: the Swedish Watchful Waiting Cohort of 615 men who underwent watchful waiting, and the U.S. Health Professionals Follow-Up Study of 849 men treated with radical prostatectomy...

Despite the spontaneous regenerative capacity of the peripheral nervous system, large gap peripheral nerve injuries (PNIs) require bridging strategies. The limitations and suboptimal results obtained with autografts or hollow nerve conduits in the clinic urge the need for alternative treatments. Recently, we have described promising neuroregenerative capacities of Schwann cells derived from differentiated human dental pulp stem cells (d-hDPSCs) in vitro. Here, we extended the in vitro assays to show the pro-angiogenic effects of d-hDPSCs, such as enhanced endothelial cell proliferation, migration and differentiation...

BACKGROUND: Despite antiretroviral therapy, it is generally believed that the risk for pneumococcal infections (PnIs) is high among patients infected with human immunodeficiency virus (HIV). However, most studies in this field have been conducted before 2010, and the proportion of virologically suppressed patients has drastically increased in these latter years thanks to larger indications and more effective antiretroviral regimens. This study aimed to re-evaluate the current risk of PnI among adult patients infected with HIV...

BACKGROUND: Muscle preservation or decrease in muscle degeneration and progressive atrophy are major challenges in patients with severe peripheral nerve injury (PNI). Considerable interest exists in the potential therapeutic value of laser phototherapy (photobiomodulation) for restoring denervated muscle atrophy and for enhancing regeneration of severely injured peripheral nerves. As previously published, the laser phototherapy has a protective and immediate effect in PNI. Laser phototherapy in the early stages of muscle atrophy may preserve the denervated muscle by maintaining creatinine kinase (CK) activity and the amount of acetylcholine receptor (AChR)...

Weijia Chen, Zhijun Lu
Microglia, rapidly activated following peripheral nerve injury (PNI), accumulate within the spinal cord and adopt inflammation that contributes to development and maintenance of neuropathic pain. Microglia express functional Toll-like receptors (TLRs), which play pivotal roles in regulating inflammatory processes. However, little is known about the role of TLR3 in regulating neuropathic pain after PNI. Here TLR3 expression and autophagy activation was assayed in dorsal root ganglions and in microglia following PNI by using realtime PCR, western blot and immunohistochemistry...

BACKGROUND: Peripheral nerve injury (PNI) can result in neurodegenerative changes leading to motor, sensory and autonomic dysfunction. Injury to the rat sciatic nerve is used to model pathophysiologic processes following PNI and assess the efficacy of therapeutic interventions. Frequently, temporal changes in the sciatic functional index (SFI), a measure of sensorimotor integration are measured in rats to assess functional recovery following sciatic nerve injury. However, multiple rat strains and behavioral endpoints have been employed to investigate pathophysiology of PNI and impact of therapeutic intervention on recovery, raising the possibility that rat strain may influence the outcome of such studies...

Peripheral nerve injury (PNI) usually results in poor functional recovery. Nerve repair is the common clinical treatment for PNI but is always obstructed by the chronic degeneration of the distal stump and muscle. Cell transplantation can alleviate the muscle atrophy after PNI, but the subsequent recovery of the locomotive function is seldom described. In this study, we combined cell transplantation and nerve repair to investigate whether the transplantation of embryonic spinal cord cells could benefit the delayed nerve repair...

Nutritional status affects the prognosis of various tumors. The prognostic nutritional index (PNI) is the known predictor of postoperative outcome in resectable pancreatic cancer patients. This study aimed to validate the prognostic value of PNI in all stages of pancreatic cancer. We retrospectively reviewed 499 patients with pancreatic cancer who were diagnosed at Severance Hospital between January 2006 and December 2011. The PNI value was calculated as 10 × serum albumin (g/dL) + 0.005 × total lymphocyte count (/mm(3)) at initial diagnosis...

Despite a substantially increased understanding of neuropathophysiology, insufficient functional recovery after peripheral nerve injury (PNI) remains a significant clinical challenge. Nerve regeneration following injury is dependent on Schwann cells, the supporting cells in the peripheral nervous system. Following nerve injury, Schwann cells adopt a pro-regenerative phenotype which supports and guides regenerating nerves. However, this phenotype may not persist long enough to ensure functional recovery. Tissue engineered nerve repair devices containing therapeutic cells that maintain the appropriate phenotype may help enhance nerve regeneration...

The prognostic nutritional index (PNI) has been reported to correlate with the prognosis in patients with various malignancies. We performed a meta-analysis to determine the predictive potential of PNI in digestive system cancers. Twenty-three studies with a total of 7,384 patients suffering from digestive system carcinomas were involved in this meta-analysis. A lower PNI was significantly associated with the shorter overall survival (OS) [Hazard Ratio (HR) 1.83, 95% Confidence Interval (CI) 1.62-2.07], the poorer disease-free survival (DFS) (HR 1...
