RESUMEN
Pressure Ulcers (PUs) remain among the most common complications after traumatic spinal cord Injuries (SCIs). The main goal of risk factor assessment with different tools has been to provisionally estimate the chance of developing pressure ulcers in patients with Spinal Cord Injury (SCI). Braden tool has been of good predictive value and most commonly employed in hospital communities for risk assessment of pressure sore development. The objective of this study was to determine the Braden risk factors as well as the prevalence of pressure injuries in SCI patients. This cross-sectional study was performed from June 2013 to December 2015 on 163 consecutive referred outpatients with chronic traumatic SCI in our tertiary SCI rehabilitation clinic. We assessed pressure induced skin injuries as well as their Braden risk factors and analyzed their association with stage and location of Pressure Ulcer (PU) and calculated prevalence of PU. One hundred and sixty-three patients out of 580 were found to have active pressure sores, with a prevalence of 28.1%. In the multiple models, only the Braden scale had significant association with the presence of active pressure sore. Patients with severe and moderate Braden scores were 2.36 and 1.82 times, more at risk of pressure sore development, as compared with those having mild scores (P≤0.01). It may be deduced that in various stages of SCI rehabilitation, the Braden scale may be calculated, and patients with moderate and severe risks (according to Braden sale) may need more attention and/or inpatient care for PU prevention.

BACKGROUND: Since the survival rate of breast cancer patients has improved, harmful effects of new treatment modalities on fertility of the young breast cancer patients has become a focus of attention. This study aimed to systematically review and critically appraise all available guidelines for fertility preservation in young breast cancer patients. MATERIALS AND METHODS: Major citation databases were searched for treatment guidelines. Experts from relevant disciplines appraised the available guidelines. The AGREE II Instrument that includes 23 criteria in seven domains (scope and purpose of the guidelines, stakeholder involvement, rigor of development, clarity, applicability, editorial independence, and overall quality) was used to apprise and score the guidelines. RESULTS: The search strategy retrieved 2,606 citations; 72 were considered for full-text screening and seven guidelines were included in the study. There was variability in the scores assigned to different domains among the guidelines. ASCO (2013), with an overall score of 68.0%, had the highest score, and St Gallen, with an overall score of 24.7%, had the lowest scores among the guidelines. CONCLUSIONS: With the promising survival rate among breast cancer patients, more attention should be given to include specific fertility preservation recommendations for young breast cancer patients.

OBJECTIVES: P In vitro chemosensitivity and resistance assays (CSRAs) are a promising tool for personalized treatment of glioblastoma multiform (GBM). These assays require a minimum of 1 to 2 g of tumor specimen for testing, but this amount is not always accessible. We aimed to assess the feasibility and validity of utilizing stereotactic biopsies of GBM in CSRAs. MATERIALS AND METHODS: Single cell suspension was prepared from 1 g weight explants of the established xenograft tumor of GBM. Also, primary culture was carried out on 35 mg weight specimens, as a surrogate for stereotactic biopsies. Then, chemoresponse profile of cells obtained by direct cell disaggregation and primary culture was determined using temozolomide and carmustine by clonogenic assay. RESULTS: There was no statistically significant difference in the cytotoxicity of temozolomide and carmustine between cells obtained from both methods. CONCLUSION: This work supports the feasibility of using stereotactic biopsies of GBM in CSRAs.
RESUMEN
BACKGROUND: Tumor angiogenesis correlates with recurrence and appears to be a prognostic factor for both breast and prostate cancers. In the present study, we aimed to investigate the correlation of microvessel density (MVD), a measure of angiogenesis, with nuclear pleomorphism, mitotic count, and vascular invasion in breast and prostate cancers at preclinical and clinical levels. METHODS: Samples from xenograft tumors of luminal B breast cancer and prostate adenocarcinoma, established by BT-474 and PC-3 cell lines, respectively, and commensurate human paraffin-embedded blocks were obtained. To determine MVD, specimens were immunostained for CD-34. Nuclear pleomorphism, mitotic count, and vascular invasion were determined using hematoxylin and eosin (HandE)-stained slides. RESULTS: MVD showed significant correlations with nuclear pleomorphism (r=0.68, P=0.03) and vascular invasion (r=0.77, P=0.009) in breast cancer. In prostate cancer, MVD was significantly correlated with nuclear pleomorphism (r=0.75, P=0.013) and mitotic count (r=0.75, P=0.012). In the breast cancer xenograft model, a significant correlation was observed between MVD and vascular invasion (r=0.87, P=0.011). In the prostate cancer xenograft model, MVD was significantly correlated with all three parameters (nuclear pleomorphism, r=0.95, P=0.001; mitotic count, r=0.91, P=0.001; and vascular invasion, r=0.79, P=0.017; respectively). CONCLUSIONS: Our results demonstrate that MVD is correlated with nuclear pleomorphism, mitotic count, and vascular invasion at both preclinical and clinical levels. This study therefore supports the predictive value of MVD in breast and prostate cancers.
