Altered calcium signaling in platelets from nitric oxide-deficient hypertensive rats
BACKGROUND: In the present study we have analyzed the mechanisms of calcium entry and mobilization in platelets obtained from rats chronically treated with the nitric oxide synthesis inhibitor, N-nitro L-arginine methyl ester [L-NAME, 40 mg/kg/day, 5 days). The platelets were obtained the day of the experiment, washed and loaded with fura-2. The intracellular calcium levels were determined in suspension of cells by means of fluorescence spectroscopy. RESULTS: Basal calcium levels were always elevated in the platelets of the L-NAME-treated rats, both in the presence and in the absence of extracellular calcium. The administration of thrombin in the absence and in the presence of extracellular calcium induced important elevations in calcium levels that were always of greater magnitude in the platelets of the L-NAME-treated rats than in those of the controls. The addition of calcium to thapsigargin-treated platelets produced a massive elevation in calcium levels in both groups that was significantly greater in the platelets obtained from the hypertensive rats than in those of the controls. CONCLUSIONS: It is concluded that the arterial hypertension induced by the reduction of nitric oxide alters the regulation of platelet calcium levels so that elevated baseline levels and calcium entry and mobilization are enhanced. This could be the result of direct or indirect effects of the lack of nitric oxide synthesis in platelets or in other tissues
Beneficial Effects of Different Flavonoids on Vascular and Renal Function in L-NAME Hypertensive Rats
Background: we have evaluated the antihypertensive effect of several flavonoid extracts
in a rat model of arterial hypertension caused by chronic administration (6 weeks) of the nitric
oxide synthesis inhibitor, L-NAME. Methods: Sprague Dawley rats received L-NAME alone or
L-NAME plus flavonoid-rich vegetal extracts (Lemon, Grapefruit + Bitter Orange, and Cocoa) or
purified flavonoids (Apigenin and Diosmin) for 6 weeks. Results: L-NAME treatment resulted in a
marked elevation of blood pressure, and treatment with Apigenin, Lemon Extract, and Grapefruit +
Bitter Orange extracts significantly reduced the elevated blood pressure of these animals. Apigenin
and some of these flavonoids also ameliorated nitric oxide-dependent and -independent aortic
vasodilation and elevated nitrite urinary excretion. End-organ abnormalities such as cardiac infarcts,
hyaline arteriopathy and fibrinoid necrosis in coronary arteries and aorta were improved by these
treatments, reducing the end-organ vascular damage. Conclusions: the flavonoids included in this
study, specially apigenin, may be used as functional food ingredients with potential therapeutic
benefit in arterial hypertension.This report was supported by a grant from the National Spanish R&D Program CENIT of

Moderate Effect of Flavonoids on Vascular and Renal Function in Spontaneously Hypertensive Rats
Many studies have shown that flavonoids are effective as antihypertensive drugs in arterial
hypertension. In the present work, we have analyzed the effects of some flavonoid extracts in the
spontaneous hypertensive rat model (SHR). An important feature of this study is that we have used a
low dose, far from those that are usually applied in human therapy or experimental animals, a dose
that responded to the criterion of a potential future commercial use in human subjects. Treatments
were carried out for 6 and 12 weeks in two groups of SHR rats, which received apigenin, lemon
extract, grapefruit + bitter orange (GBO) extracts, and cocoa extract. Captopril was used as a positive
control in the SHR group treated for 6 weeks (SHR6) and Diosmin was used as the industry reference
in the SHR group treated for 12 weeks (SHR12). Captopril and GBO extracts lowered the high arterial
pressure of the SHR6 animals, but none of the extracts were effective in the SHR12 group. Apigenin,
lemon extract (LE), GBO, and captopril also improved aortic vascular relaxation and increased plasma
and urinary excretion of nitrites, but only in the SHR6 group. Kidney and urinary thiobarbituric acid
reactive substances (TBARS) were also significantly reduced by GBO in the SHR6 rats. Apigenin also
improved vascular relaxation in the SHR12 group and all the flavonoids studied reduced urinary
thiobarbituric acid reactive substances (TBARS) excretion and proteinuria. Vascular abnormalities,
such as lumen/wall ratio in heart arteries and thoracic aorta, were moderately improved by these
treatments in the SHR6 group. In conclusion, the flavonoid-rich extracts included in this study,
especially apigenin, LE and GBO improved vascular vasodilatory function of young adult SHRs but
only the GBO-treated rats benefited from a reduction in blood pressure. These extracts may be used
as functional food ingredients with a moderate therapeutic benefit, especially in the early phases of
arterial hypertension.This report was supported by a grant from the National Spanish R & D Program CENIT of the Spanish

Incidence and clinical manifestations of giant cell arteritis in Spain: results of the ARTESER register
Objective This study aimed to estimate the incidence of giant cell arteritis (GCA) in Spain and to analyse its clinical manifestations, and distribution by age group, sex, geographical area and season.Methods We included all patients diagnosed with GCA between 1 June 2013 and 29 March 2019 at 26 hospitals of the National Health System. They had to be aged >= 50 years and have at least one positive results in an objective diagnostic test (biopsy or imaging techniques), meet 3/5 of the 1990 American College of Rheumatology classification criteria or have a clinical diagnosis based on the expert opinion of the physician in charge. We calculated incidence rate using Poisson regression and assessed the influence of age, sex, geographical area and season.Results We identified 1675 cases of GCA with a mean age at diagnosis of 76.9 +/- 8.3 years. The annual incidence was estimated at 7.42 (95% CI 6.57 to 8.27) cases of GCA per 100 000 people >= 50 years with a peak for patients aged 80-84 years (23.06 (95% CI 20.89 to 25.4)). The incidence was greater in women (10.06 (95% CI 8.7 to 11.5)) than in men (4.83 (95% CI 3.8 to 5.9)). No significant differences were found between geographical distribution and incidence throughout the year (p=0.125). The phenotypes at diagnosis were cranial in 1091 patients, extracranial in 337 patients and mixed in 170 patients.Conclusions This is the first study to estimate the incidence of GCA in Spain at a national level. We found a predominance among women and during the ninth decade of life with no clear variability according to geographical area or seasons of the year
Inter-Rater Variability in the Evaluation of Lung Ultrasound in Videos Acquired from COVID-19 Patients
12 páginas, 7 figuras, 1 tablaLung ultrasound (LUS) allows for the detection of a series of manifestations of COVID-19,
such as B-lines and consolidations. The objective of this work was to study the inter-rater reliability
(IRR) when detecting signs associated with COVID-19 in the LUS, as well as the performance of the
test in a longitudinal or transverse orientation. Thirty-three physicians with advanced experience in
LUS independently evaluated ultrasound videos previously acquired using the ULTRACOV system
on 20 patients with confirmed COVID-19. For each patient, 24 videos of 3 s were acquired (using
12 positions with the probe in longitudinal and transverse orientations). The physicians had no
information about the patients or other previous evaluations. The score assigned to each acquisition
followed the convention applied in previous studies. A substantial IRR was found in the cases of
normal LUS (κ = 0.74), with only a fair IRR for the presence of individual B-lines (κ = 0.36) and for
confluent B-lines occupying 50%
(κ = 0.50). No statistically significant differences between the longitudinal and transverse scans were
found. The IRR for LUS of COVID-19 patients may benefit from more standardized clinical protocols.This research was partially funded by CDTI (Spanish acronym: Centre for Industrial Tech-

COVID-19 Severity and Survival over Time in Patients with Hematologic Malignancies: A Population-Based Registry Study
Mortality rates for COVID-19 have declined over time in the general population, but data in patients with hematologic malignancies are contradictory. We identified independent prognostic factors for COVID-19 severity and survival in unvaccinated patients with hematologic malignancies, compared mortality rates over time and versus non-cancer inpatients, and investigated post COVID-19 condition. Data were analyzed from 1166 consecutive, eligible patients with hematologic malignancies from the population-based HEMATO-MADRID registry, Spain, with COVID-19 prior to vaccination roll-out, stratified into early (February–June 2020; n = 769 (66%)) and later (July 2020–February 2021; n = 397 (34%)) cohorts. Propensity-score matched non-cancer patients were identified from the SEMI-COVID registry. A lower proportion of patients were hospitalized in the later waves (54.2%) compared to the earlier (88.6%), OR 0.15, 95%CI 0.11–0.20. The proportion of hospitalized patients admitted to the ICU was higher in the later cohort (103/215, 47.9%) compared with the early cohort (170/681, 25.0%, 2.77; 2.01–3.82). The reduced 30-day mortality between early and later cohorts of non-cancer inpatients (29.6% vs. 12.6%, OR 0.34; 0.22–0.53) was not paralleled in inpatients with hematologic malignancies (32.3% vs. 34.8%, OR 1.12; 0.81–1.5). Among evaluable patients, 27.3% had post COVID-19 condition. These findings will help inform evidence-based preventive and therapeutic strategies for patients with hematologic malignancies and COVID-19 diagnosis.Depto. de MedicinaFac. de MedicinaTRUEFundación Madrileña de Hematología y HemoterapiaFundación Leucemia y LinfomaAsociación Madrileña de Hematología y Hemoterapiapu
