Vascular Endothelial Growth Factor A Signaling Promotes Spinal Central Sensitization and Pain-related Behaviors in Female Rats with Bone Cancer

This study tested the hypothesis that vascular endothelial growth factor A and vascular endothelial growth factor receptor 2 contribute to bone cancer pain regulation associated with spinal central sensitization.Methods This study was performed on female rats using a metastatic breast cancer bone pain model. Nociceptive behaviors were evaluated by mechanical allodynia, thermal hyperalgesia, spontaneous pain, and CatWalk gait analysis. Expression levels were measured by real-time quantitative polymerase chain reaction, western blot, and immunofluorescence analysis. Excitatory synaptic transmission was detected by whole-cell patch-clamp recordings. The primary outcome was the effect of pharmacologic intervention of spinal vascular endothelial growth factor A/vascular endothelial growth factor receptor 2 –signaling on bone cancer pain behaviors.Results The mRNA and protein expression of vascular endothelial growth factor A and vascular endothelial growth factor receptor 2 were upregulated in tumor-bearing rats. Spinal blocking vascular endothelial growth factor A or vascular endothelial growth factor receptor 2 significantly attenuated tumor-induced mechanical allodynia (mean ± SD: vascular endothelial growth factor A, 7.6 ± 2.6 gvs. 5.3 ± 3.3 g; vascular endothelial growth factor receptor 2, 7.8 ± 3.0 gvs. 5.2 ± 3.4 g; n = 6;P

CONCLUSIONS: Awareness of possible repercussions of the celiac trunk stenosis to peripancreatic arteries should be elevated. Restoration of physiological blood flow by removing pathologic anatomy should be performed. Since there is no correlation between the size of a visceral aneurysm and the risk of rupture, having a high postrupture mortality, pancreaticoduodenal artery aneurysms should be treated even if asymptomatic. Surgical treatment remains the mainstay treatment of the Dunbar syndrome complicated by visceral aneurysms. PMID: 31961777 [PubMed - as supplied by publisher]

ConclusionHigh levels of lifestyle-related cancer-risk behaviors were found in most of the Hong Kong construction workers studied. The present study contributes to understanding how cancer-related lifestyle risk behaviors cluster among construction workers and relative impact factors of risk behaviors. It is essential to tailor health behavior interventions focused on multiple risk behaviors among different groups for further enlarging the effects on cancer prevention.

We report one case, in which the patient presented to the emergency department with lower urinary tract symptoms, fever and consumptive syndrome. Acute prostatitis was initially suspected, but subsequently prostate adenocarcinoma was diagnosed.This case enables us to consider the possibility of prostate adenocarcinoma as the diagnose in patients with fever of unknown origin, and the role of procalcitonin to rule out the presence of infection.

CooperbergAbstractBackgroundActive surveillance (AS)/watchful waiting (WW) strategy for localized prostate cancer (PCa) is increasingly and broadly endorsed as a preferred option for initial treatment of men with very low- and low-risk PCa, but outcomes can be difficult to analyze in traditional, population-based registries. The recently released Surveillance, Epidemiology, and End Results (SEER) Prostate with WW dataset provides an op...

Written By Myra ChristopherMy mom was a steel magnolia (i.e., southern and perfectly charming), but she had a steel rod up her back. After her first surgery for stomach cancer at age 53, she refused pain medication because she said that she “could take it.” She was young and strong and committed to “beating cancer.” After nearly two years of chemotherapy, radiation and two more surgeries, the cancer won. Eventually, I watched her beg nurses to give her “a shot” minutes before another was scheduled and be told they were sorry but she would have to wait. I could tell by the expressions on ...

This study builds on preliminary findings from the first phase of the INTERSTROKE study, which identified ten modifiable risk factors for stroke in 6,000 participants from 22 countries. The full-scale INTERSTROKE study included an additional 20,000 individuals from 32 countries in Europe, Asia, America, Africa and Australia, and sought to identify the main causes of stroke in diverse populations, young and old, men and women, and within subtypes of stroke. To estimate the proportion of strokes caused by specific risk factors, the investigators calculated the population attributable risk for each factor (PAR; an esti...

The objective of this study was to investigate the measures of pain at distant non-tumor-bearing sites in animals with localized bone metastasis. Immunocompetent BALB/c mice are injected intra-tibially with murine mammary carcinoma cells (4T1) or saline, and the sensitivity to mechanical and thermal stimuli in the contralateral paw was examined. In addition to previously demonstrated development of osteolysis and hypersensitivity to mechanical and thermal stimuli in the cancer-injected tibia, these animals exhibited an increase in sensory hypersensitivity in the contralateral limb. No bone lesions were evident on radiograp...
