Introduction and objectives Cardiovascular disease continues to be the main cause of mortality, but few data are available in the young population. The aim of our study was to know the incidence and clinical characteristics of premature cardiovascular disease in our health area. Methods Cross-sectional study of patients admitted for acute episode of premature cardiovascular disease in a referral hospital during 2018. Results We detected 367 subjects: 306 (83.4%) with atherosclerotic cardiovascular disease. Almost half (164, 44.7%) were diabetic, with primary hypercholesterolaemia or high cardiovascular risk, and 84 (22.9%) had a personal history of cardiovascular disease. Among those with elevated risk or history (n=207) only 47 subjects had LDL cholesterol at therapeutic target. Conclusions Most of the subjects with premature cardiovascular disease in our study had higher cardiovascular risk than attributable to their age. Intensive diagnosis and treatment of cardiovascular risk factors may prevent cardiovascular disease in young adults (AU)

Predictive factors of six-week mortality in critically ill patients with SARS-CoV-2: A multicenter prospective study.

OBJECTIVE: The objective of the study is to identify the risk factors associated with mortality at six weeks, especially by analyzing the role of antivirals and munomodulators. DESIGN: Prospective descriptive multicenter cohort study. SETTING: 26 Intensive care units (ICU) from Andalusian region in Spain. PATIENTS OR PARTICIPANTS: Consecutive critically ill patients with confirmed SARS-CoV-2 infection were included from March 8 to May 30. INTERVENTIONS: None. VARIABLES: Variables analyzed were demographic, severity scores and clinical condition. Support therapy, drug and mortality were analyzed. An univariate followed by multivariate Cox regression with propensity score analysis was applied. RESULTS: 495 patients were enrolled, but 73 of them were excluded for incomplete data. Thus, 422 patients were included in the final analysis. Median age was 63 years and 305 (72.3%) were men. ICU mortality: 144/422 34%; 14 days mortality: 81/422 (19.2%); 28 days mortality: 121/422 (28.7%); 6-week mortality 152/422 36.5%. By multivariable Cox proportional analysis, factors independently associated with 42-day mortality were age, APACHE II score, SOFA score at ICU admission >6, Lactate dehydrogenase at ICU admission >470U/L, Use of vasopressors, extrarenal depuration, %lymphocytes 72h post-ICU admission <6.5%, and thrombocytopenia whereas the use of lopinavir/ritonavir was a protective factor. CONCLUSION: Age, APACHE II, SOFA>value of 6 points, along with vasopressor requirements or renal replacement therapy have been identified as predictor factors of mortality at six weeks. Administration of corticosteroids showed no benefits in mortality, as did treatment with tocilizumab. Lopinavir/ritonavir administration is identified as a protective factor.

Effect of homeostatic T-cell proliferation in the vaccine responsiveness against influenza in elderly people.

BACKGROUND: Seasonal influenza virus infection is a significant cause of morbimortality in the elderly. However, there is poor vaccine efficacy in this population due to immunosenescence. We aimed to explore several homeostatic parameters in the elderly that could impact influenza vaccine responsiveness. METHODS: Subjects (> 60 years old) who were vaccinated against influenza virus were included, and the vaccine response was measured by a haemagglutination inhibition (HAI) test. At baseline, peripheral CD4 and CD8 T-cells were phenotypically characterized. Thymic function and the levels of different inflammation-related biomarkers, including Lipopolysaccharide Binding Protein (LBP) and anti-cytomegalovirus (CMV) IgG antibodies, were also measured. RESULTS: Influenza vaccine non-responders showed a tendency of higher frequency of regulatory T-cells (Tregs) before vaccination than responders (1.49 [1.08-1.85] vs. 1.12 [0.94-1.63], respectively, p = 0.061), as well as higher expression of the proliferation marker Ki67 in Tregs and different CD4 and CD8 T-cell maturational subsets. The levels of inflammation-related biomarkers correlated with the frequencies of different proliferating T-cell subsets and with thymic function (e.g., thymic function with D-dimers, r = - 0.442, p = 0.001). CONCLUSIONS: Age-related homeostatic dysregulation involving the proliferation of CD4 and CD8 T-cell subsets, including Tregs, was related to a limited responsiveness to influenza vaccination and a higher inflammatory status in a cohort of elderly people.

Geographic and Temporal Variation of Distinct Intracellular Endosymbiont Strains of Wolbachia sp. in the Grasshopper Chorthippus parallelus: a Frequency-Dependent Mechanism?

Wolbachia is an intracellular endosymbiont that can produce a range of effects on host fitness, but the temporal dynamics of Wolbachia strains have rarely been experimentally evaluated. We compare interannual strain frequencies along a geographical region for understanding the forces that shape Wolbachia strain frequency in natural populations of its host, Chorthippus parallelus (Orthoptera, Acrididae). General linear models show that strain frequency changes significantly across geographical and temporal scales. Computer simulation allows to reject the compatibility of the observed patterns with either genetic drift or sampling errors. We use consecutive years to estimate total Wolbachia strain fitness. Our estimation of Wolbachia fitness is significant in most cases, within locality and between consecutive years, following a negatively frequency-dependent trend. Wolbachia spp. B and F strains show a temporal pattern of variation that is compatible with a negative frequency-dependent natural selection mechanism. Our results suggest that such a mechanism should be at least considered in future experimental and theoretical research strategies that attempt to understand Wolbachia biodiversity.

Respuestas cardiorrespiratorias a intensidad umbral. Estudio comparativo entre media sentadilla y cicloergómetro / Cardiorrespiratory responses at threshold intensity. Comparative between half squat vs cycle ergometer

Objetivo: Comparar las respuestas respiratorias, de frecuencia cardíaca (FC) y lactato a intensidad de umbral láctico (UL) en media sentadilla (MS) vs cicloergómetro. Métodos: 24 hombres (21,5±1,8 años, 180,1±5,2 cm, 81,9±8,7 kg) con experiencia en el entrenamiento de fuerza realizaron un test incremental progresivo en MS y cicloergómetro para determinar el UL. Durante los test se midieron las concentraciones de lactato, FC, consumo de oxígeno (VO2), producción de dióxido de carbono (VCO2), ventilación pulmonar (VE), equivalente ventilatorio del oxígeno (VE·VO2-1) y del dióxido de carbono (VE·VCO2-1). Una t student valoró las diferencias entre las dos modalidades de ejercicio. Resultados: las concentraciones de lactato, FC, VE, VE·VCO2-1 y VE·VO2-1 fueron superiores en MS vs cicloergómetro (p<0,05). Conclusiones: el UL puede ser detectado en el ejercicio de MS. Además, la realización de sesiones de entrenamiento contrarresistencias, a intensidad de UL, podrían ser utilizadas para mejorar la resistencia cardiovascular y la fuerza muscular

Objective: To compare respiratory responses, heart rate (HR) and lactate at the intensity of the lactate threshold (LT) between half squat (HS) and cycloergometer. Methods: 24 men (21.5±1.8 years, 180.1 ± 5.2 cm, 81.9±8.7 kg) with experience in resitance performed a progressive incremental test in HS and cycloergometer to determine LT. During such test, the following parameters were measured: blood lactate concentrations, HR, oxygen consumption (VO2), carbon dioxide production (VCO2), pulmonary ventilation (PV), ventilatory equivalent of oxygen (PV·VO2-1) and ventilatory equivalent of carbon dioxide (PV·VCO2-1). A t student evaluated the variables analysed among the two exercise modalities. Results: blood lactate concentrations, HR, PV, and PV·VO2-1 and PV·VCO2-1 were higher in HS than in cycloergometer (p <0.05). Conclusions: LT can be detected in HS exercise. Furthermore, the resistance training sessions to the intensity of LT might be used in training sessions which seek to improve cardiovascular endurance and muscle strength

[Multilocus Sequence Typing analysis of human Campylobacter coli in Granada (Spain)].

OBJECTIVE: Different subtypes of Campylobacter spp. have been associated with diarrhoea and a Multilocus Sequence Typing (MLST) method has been performed for subtyping. In the present work, MLST was used to analyse the genetic diversity of eight strains of Campylobacter coli. METHODS: Nineteen genetic markers were amplified for MLST analysis: AnsB, DmsA, ggt, Cj1585c, CJJ81176-1367/1371, Tlp7, cj1321-cj1326, fucP, cj0178, cj0755/cfrA, ceuE, pldA, cstII, cstIII. After comparing the obtained sequences with the Campylobacter MLST database, the allele numbers, sequence types (STs) and clonal complexes (CCs) were assigned. RESULTS: The 8 C. coli isolates yielded 4 different STs belonging to 2 CCs. Seven isolates belong to ST-828 clonal complex and only one isolate belong to ST-21. Two samples came from the same patient, but were isolated in two different periods of time. CONCLUSIONS: MLST can be useful for taxonomic characterization of C. coli isolates.

Non-pharmacological treatment for neuropathic pain in children with cancer.

Neuropathic pain (NP) associated with childhood cancer is currently a difficult problem to control. It is treated with drugs that not only fail to provide the expected improvements, but which also have side effects. Therefore, the main aim of this pilot study is to assess whether non-pharmacological treatments, Graded Motor Imagery (GMI) and Neural Mobilization (NM), have a positive effect on this pain, thus improving the associated comorbid factors and, consequently, the quality of life of the children. In an n = 6, the results after 4 weeks of treatment show a 10-point improvement in the pain threshold and a 3.1-point improvement in the perception of pain.

Molecular characterization of enteroviruses associated with neurological infections in Spain, 2008.

In order to investigate the etiology of viral neurological infections in Spain, a national study was performed in 2008. The results obtained have been published. Enteroviruses were the most frequent cause of the aseptic meningitis and infant febrile syndromes. The present report supplements the previous study with the genotyping of the detected enteroviruses. Typing was by amplification of partial VP1 region and sequencing in 70 (53%) of the 132 available cerebrospinal fluid samples positive for enteroviruses. Twelve different genotypes within the B species were identified. Echovirus 4 was predominant (24%), followed by echovirus 30 (19%), echovirus 9 (17%), and echovirus 6 (14%). In summary, a co-circulation of several enterovirus types associated with meningitis in children under 15 years old was observed. Although infrequently detected, echovirus 4 was the predominant genotype identified due to an aseptic meningitis outbreak which occurred in the Canary Islands in 2008.

Viral infections of the central nervous system in Spain: a prospective study.

The aim of the study was to determine the incidence of viruses causing aseptic meningitis, meningoencephalitis, and encephalitis in Spain. This was a prospective study, in collaboration with 17 Spanish hospitals, including 581 cases (CSF from all and sera from 280): meningitis (340), meningoencephalitis (91), encephalitis (76), febrile syndrome (7), other neurological disorders (32), and 35 cases without clinical information. CSF were assayed by PCR for enterovirus (EV), herpesvirus (herpes simplex [HSV], varicella-zoster [VZV], cytomegalovirus [CMV], Epstein-Barr [EBV], and human herpes virus-6 [HHV-6]), mumps (MV), Toscana virus (TOSV), adenovirus (HAdV), lymphocytic choriomeningitis virus (LCMV), West Nile virus (WNV), and rabies. Serology was undertaken when methodology was available. Amongst meningitis cases, 57.1% were characterized; EV was the most frequent (76.8%), followed by VZV (10.3%) and HSV (3.1%; HSV-1: 1.6%; HSV-2: 1.0%, HSV non-typed: 0.5%). Cases due to CMV, EBV, HHV-6, MV, TOSV, HAdV, and LCMV were also detected. For meningoencephalitis, 40.7% of cases were diagnosed, HSV-1 (43.2%) and VZV (27.0%) being the most frequent agents, while cases associated with HSV-2, EV, CMV, MV, and LCMV were also detected. For encephalitis, 27.6% of cases were caused by HSV-1 (71.4%), VZV (19.1%), or EV (9.5%). Other positive neurological syndromes included cerebellitis (EV and HAdV), seizures (HSV), demyelinating disease (HSV-1 and HHV-6), myelopathy (VZV), and polyradiculoneuritis (HSV). No rabies or WNV cases were identified. EVs are the most frequent cause of meningitis, as is HSV for meningoencephalitis and encephalitis. A significant number of cases (42.9% meningitis, 59.3% meningoencephalitis, 72.4% encephalitis) still have no etiological diagnosis.

Measles outbreak in Andalusia, Spain, January to August 2011.

On 7 January 2011, a six year-old child living in a Roma community near Seville, southern Spain, was hospitalised with measles. Contact tracing identified a probable index case with onset of symptoms on 20 December 2011 and several unreported cases among children under the age of 15 years in the same town. The outbreak initially spread in districts in the city of Seville with a high proportion of Roma residents, and later to other cities and towns in Andalusia. While some towns experienced wide spread of the disease with significant clusters of cases, most of the affected locations saw non-clustered cases or very few secondary cases. The outbreak resulted in 1,759 confirmed or probable cases of which 393 (19%) required hospitalisation. Measles virus of genotype D4 was diagnosed in more than half of the cases. Significant differences (p<0.0001) by age group were found between clustered and non-clustered cases. The highest proportion of clustered cases occurred in the age group of 5-14 yearolds, while the highest proportion of non-clustered cases was seen in those older than 29 years. The last confirmed case related to this outbreak was reported on 20 August 2011.

[Infection by the pandemic virus (H1N1) 2009 in Andalusia]. / Infección por virus pandémico (H1N1) 2009 en Andalucía.

In April 2009, in response to the WHO's alert due to the existence of human infection cases with a new AH1N1 influenza virus, known as swine flu, Andalusian Health Authorities trigger an specific action plan. The surveillance actions developped provided us with appropriate clinical, epidemiological and virological characteristics of the disease. During the first few days, contingency plans were set up based on epidemiological surveillance and outbreak control measures were adopted through early alert and rapid response systems. After phase 6 was declared, influenza sentinel and severe cases surveillance were used in order to plan healthcare services, to reduce transmission and to identify and protect the most vulnerable population groups. Behaviour of pandemic influenza in Andalusia was similar to that observed in the rest of the world. Atack rate was similar to a seasonal flu and the peak was reached at the 46th/2009 week. Most of them were mild cases and affected particularly to young people. The average age of hospitalised patients was 32. Prior pulmonary disease, smoking and morbid obesity (BMI > 40) were the most common pathologies and risk factors in severe cases. An impact scenario of pandemic wave in Andalusia, with an expected attack rate from 2 to 5%, was prepared considering watt observed in the southern hemisphere. Characteristics of the epidemic concerning its extent, severity and mortality rate were adjusted to this scenario.

Behaviour of the pandemic H1N1 influenza virus in Andalusia, Spain, at the onset of the 2009-10 season.

In Andalusia, Spain, the pandemic influenza A(H1N1)v virus has spread throughout the community, being the dominant influenza strain in the season so far. The current objective of the Andalusia Health Service is focussed on the mitigation of the health and social impact by appropriate care of the patients at home or in health centres. The 2009-10 seasonal influenza epidemic started early compared with to previous seasons. This article analyses the influenza A(H1N1)v situation in Andalusia until the week 39/2009.
