Abstract
Cancer is understood as a multifactorial disease that involve multiple cell types and phenotypes in the tumor microenvironment (TME). The components of the TME can interact directly or via soluble factors (cytokines, chemokines, growth factors, extracellular vesicles, etc.). Among the cells composing the TME, mesenchymal stem cells (MSCs) appear as a population with debated properties since it has been seen that they can both promote or attenuate tumor progression. For various authors, the main mechanism of interaction of MSCs is through their secretome, the set of molecules secreted into the extracellular milieu, recruiting, and influencing the behavior of other cells in inflammatory environments where they normally reside, such as wounds and tumors. Natural products have been studied as possible cancer treatments, appealing to synergisms between the molecules in their composition; thus, extracts obtained from Petiveria alliacea (Anamu-SC) and Caesalpinia spinosa (P2Et) have been produced and studied previously on different models, showing promising results. The effect of plant extracts on the MSC secretome has been poorly studied, especially in the context of the TME. Here, we studied the effect of Anamu-SC and P2Et extracts in the human adipose-derived MSC (hAMSC)-tumor cell interaction as a TME model. We also investigated the influence of the hAMSC secretome, in combination with these natural products, on tumor cell hallmarks such as viability, clonogenicity, and migration. In addition, hAMSC gene expression and protein synthesis were evaluated for some key factors in tumor progression in the presence of the extracts by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and Multiplex, respectively. It was found that the presence of the hAMSC secretome did not affect the cytotoxic or clonogenicity-reducing activities of the natural extracts on cancer cells, and even this secretome can inhibit the migration of these tumor cells, in addition to the fact that the profile of molecules can be modified by natural products. Overall, our findings demonstrate that hAMSC secretome participation in TME interactions can favor the antitumor activities of natural products.

Abstract
BACKGROUND AND PURPOSE Elevated plasma uric acid has been inconsistently associated with an increased risk of total stroke; however, data are sparse amongst women. The association between plasma uric acid concentrations and ischaemic stroke amongst women was examined and the effect modification by key cardiovascular risk factors was evaluated. METHODS A nested case-control design with matching by age, race/ethnicity, smoking status, menopausal status, postmenopausal hormone therapy use, date of blood draw and fasting status was utilized amongst female participants of the Nurses' Health Study who provided blood samples between 1989 and 1990. Plasma uric acid was measured on stored blood samples. The National Survey of Stroke criteria were utilized to confirm 460 incident cases of ischaemic stroke by medical records from 1990 to 2006. Multivariable conditional logistic regression models were estimated. RESULTS In matched analysis, risk of ischaemic stroke increased by 15% for each 1 mg/dl increase in plasma uric acid [95% confidence interval (CI) 3%-28%], but was no longer significant after adjustment for cardiovascular risk factors, particularly history of hypertension. The highest quartile of uric acid was significantly associated with greater risk of ischaemic stroke (relative risk 1.56; 95% CI 1.06-2.29, extreme quartiles) in matched analysis, but estimates were no longer significant after adjustment for cardiovascular risk factors (relative risk 1.43; 95% CI 0.93-2.18). Significant effect modification by key cardiovascular risk factors was not observed. CONCLUSIONS Plasma uric acid levels were not independently associated with increased risk of ischaemic stroke in this cohort of women. Whilst plasma uric acid was associated with stroke risk factors, it was not independently associated with stroke risk.

Abstract
INTRODUCTION Currently, clinical benefits of stroke units and thrombolysis in ischaemic stroke are evidence-based. However, inequities in coverage and in treatment provided to these patients still persist due to geographical differences in residence, technological capacity and organization among health care systems. Telestroke is considered to be an effective tool for reducing inequities in coverage and health outcomes of stroke patients. DEVELOPMENT This paper reviews the requirements of implementation of telestroke units, their deployment in the Health Service of the Balearic Islands, and the main experiences reported so far. Further, preliminary results of an ongoing formal assessment of effectiveness and safety of telestroke relative to conventional stroke treatment are advanced. CONCLUSIONS Implementation of a telestroke system is feasible and allows increasing specialized treatment coverage. The Health Service of the Balearic Islands is fulfilling its goal of improving thrombolysis coverage by means of telestroke. Its effectiveness and safety appear to be similar to those of conventional treatment.

Abstract
The aim of the present study was to assess the impact of nasal continuous positive airway pressure (nCPAP) in ischaemic stroke patients followed for 2 yrs. Stroke patients with an apnoea-hypopnoea index ≥ 20 events·h⁻¹ were randomised to early nCPAP (n = 71; 3-6 days after stroke onset) or conventional treatment (n = 69). The Barthel Index, Canadian Scale, Rankin Scale and Short Form-36 were measured at baseline, and at 1, 3, 12 and 24 months. The percentage of patients with neurological improvement 1 month after stroke was significantly higher in the nCPAP group (Rankin scale 90.9 versus 56.3% (p < 0.01); Canadian scale 88.2 versus 72.7% (p < 0.05)). The mean time until the appearance of cardiovascular events was longer in the nCPAP group (14.9 versus 7.9 months; p = 0.044), although cardiovascular event-free survival after 24 months was similar in both groups. The cardiovascular mortality rate was 0% in the nCPAP group and 4.3% in the control group (p = 0.161). Early use of nCPAP seems to accelerate neurological recovery and to delay the appearance of cardiovascular events, although an improvement in patients' survival or quality of life was not shown.

Abstract
p53 mutation are currently recognized as the commonest genetic event in human tumors. In this paper are studied, through immunochemistry, the p53 protein expression of 25 carriers from squamous cell carcinoma of the larynx and hypopharynx as well in the non tumoral mucosa of the larynx removed and corresponding metastases. Because of the great overexpression of this protein among tumors and its metastases, aside with the low expression in normal far-off mucous membranes of the studied growths, the AA. draw out the conclusion that p53 mutation is a late event by neck and head oncogenesis.

Abstract
The Ves-MaticR system (VS) for evaluating erythrocyte sedimentation rate (ESR) is compared to Westergren method. A good correlation between both methods is obtained in spite of small differences observed; the accuracy of the VS is also studied. Concerning the time variation, a small reduction of the ESR in the first seven hours is observed, being significant at 24 hours. The most important advantages of the VS are the near complete disappearance of the contamination risk, the reduction of the time employed in setting up, sedimentation and reading, and the reliability.
