Resumen Este modesto, deslabazado e insignificante trabajo de Algas de agua dulce, se lo dedico con mucho cariñ, veneració y respeto, al gran maestro de la Ficologia Prof. De Toni (q. e. p.d.). Las tres especies nuevas y la variedad, se las dedico a él. Oedogonium De-Tonii, Phythelios De-Tonii y Rivularia beccariana var. De toniana, han sido cogidas en las aguas dulces de España, de las regiones hidrograficas de los rios Guadiana y Tajo, mientras que Catena De-toniana la cogi, en la margen izquierda del rio Valtournance, próximo al Matterhorn. Las diagnosis se dan en latin. En cada especie se hacen observaciones referentes a la ontogenia, ecologia, etc., de tales especies criptogamicas nuevas, al final, se dibujan tales novedades cientificas, y se acompañan de fotografias, que indican el habitat en el cual fueron halladas las especies. En Rivularia he preferido la fotografia macro-scopica de los talos a la que indicase, el lugar de su captura, como se hace en las otras especies. La critica botanica tiene la palabra. 相似文献

ObjectivesTo estimate the prevalence of obesity and overweight in children and adolescents in our city and to investigate the associated factors.Subjects and methodsA cross-sectional study of 1317 children and adolescents aged 2-16 years. Multistage probability sampling was used to select three groups of subjects: 411 aged 12 to 16 years, 504 aged 6 to 12 years, and 402 aged 2 to 6 years. Body mass index was calculated, and obesity and overweight were diagnosed using the threshold levels of the International Obesity Task Force for children and adolescents. Parents were asked about eating habits, health, social, and demographic aspects. Results are given as percentages (95% confidence interval). The relationship between obesity and overweight and the different variables was studied using multiple logistic regression. The adjusted odds ratio (OR) was calculated.ResultsAmong children and adolescentes aged 2-16 years, 9.5% (8.0%-11.0%) were obese and 22.4% (23.3%-24.6%) were overweight. Of subjects aged 12-16 years, 8.5% (5.9%-11.2%) were obese and 20.5% (16.7%-24.3%) were overweight. In the groups aged 6-12 years and 2-6 years, rates of obesity and overweight were 11.6% (8.9% -14.3%) and 31.0% (27.0-35.0) and 8.0% (5.4%-10.6%) and 13.6% (10.3%-16.9%) respectively. Obesity or overweight was associated to age (OR 1.21; P< 0.001), maternal obesity (OR 10.99; P= 0.008), a birthweight higher than 4 kg (OR 2.91; p 0.002), and formula feeding (OR 1.82; P= 0.005).ConclusionObesity and overweight in children and adolescents are highly prevalent problems in our city. 相似文献

Background and objectiveCOVID-19 is a disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and has caused a global pandemic that we are currently suffering from.Objectiveto identify factors associated with the death of patients aged 65 years or older hospitalized for COVID-19.Materials and methodsRetrospective cohort study. We included patients aged 65 years or older who were hospitalized for COVID-19 and dead o discharged between March 5 and 25, 2020. We used univariable and multivariable logistic regression methods to explore the risk factors associated with in-hospital death.Results277 patients were included in this study. The bivariate analysis showed significant differences (p < 0.05) between survivors and non survivors: age, increased dependence and comorbidity, history of ischemic heart disease, renal failure and non-hematological neoplasms, heart failure during admission, leukocytosis, elevated creatinine, PCR, GOT and troponin Ic values, lymphopenia, and decreased blood pH and SatO2. Multivariate logistic regression revealed that age ≥ 65 years (OR: 4.23 (95% CI: 1.43-12.52; p = 0.009), lymphopenia < 1000/μL (OR: 2.36 (95% CI: 1.07-5.20; p = 0.033), creatinine > 1.2 mg/dL (OR: 3.08 (95% CI: 1.37-6.92; p = 0.006), SatO2 < 90% (OR: 2.29 (95% CI: 1.01-5.21; p = 0.049) and troponin Ic > 11 ng/mL (OR: 2.32 (95% CI: 1.04-5.16; p = 0.040) were independently associated with higher hospital mortality.ConclusionsOlder age, lymphopenia, SatO2 < 90%, elevated creatinine and troponin Ic values were independently associated with higher mortality in hospitalized patients with COVID-19, these factors could help clinicians to identify patients with poor prognosis. 相似文献

BackgroundThe aim of this study was to analyse the trend in the percentages of elderly patients admitted to hospital for psychiatric reasons. An additional aim was to analyse the characteristics of the elderly population admitted to a psychiatric hospitalisation unit.Material an MethodsAn analysis was made of the trends in the percentages of discharges in elderly population at the national level and in the Mental Health Hospitalisation Unit (MHHU) of the Regional University Hospital of Malaga for a period of at least 18 years using segmented regression. For the study of the characteristics of the elderly population, all patients (N = 5,925) and consecutive episodes of admission (N = 15,418) were compared between 1999 and 2017 in the MHHU.ResultsAt the national level, there was an increase in hospital discharges in elderly patients with a significant mean annual percent change of 2.0%. In the study unit, the elderly population were more frequently female, involuntarily admitted, and had a longer hospital stay. They had been diagnosed more frequently with organic and depressive mental disorders, and less frequently with schizophrenia, substance use, and personality disorders.ConclusionsThere was a growing trend in the percentage of elderly psychiatric patients admitted to hospitals during the study period. These results point to the increase in elderly psychiatric admissions and thus the need to adapt psychiatric units to the characteristics of this population. 相似文献

Introduction
The prevalence of cognitive impairment with no dementia (CIND) varies between 5.1% and 35.9%, increasing between 65 and 85 years. The CIND increases the risk of dementia. Factors such as education, occupation, and social activities are associated with the risk of cognitive impairment. The main objective of this study was to analyse the association between the main occupation developed throughout life and CIND in a general population sample of over 55 years.Methods
In wave I of the ZARADEMP Project, a sample (n = 4803) of people over 55 years was interviewed. CIND measurement was obtained through the Mini Mental State Examination. Occupational activity data were recoded into white collar, blue collar, homemakers, and farmers. The association between the occupation variables and CIND was estimated using the odds ratio, and 95% confidence intervals using logistic regression equations.Results
The prevalence of CIND in the sample was 28.2%. As regards white collar workers, the CIND diagnosis odds was 53% higher for blue collar workers, 77% higher for women who were homemakers and almost twice for farmers, after controlling for socio-demographic, behavioural and clinical variables. All results were statistically significant.Conclusions
CIND frequency is influenced by the previous occupation of the subjects. An occupation with higher intellectual requirements can help keep cognitive functions intact for longer. 相似文献17.

Introduction
In the current context of increased life expectancy and progressive aging of the population a very significant increase in the number of people with cognitive impairment and dementia is expected.Consequently, Spain will face an enormous social and health problem in the next decades. The Mapa de la enfermedad de Alzheimer y otras demencias en España project aims to analyse plans, prevention and early diagnosis activities, process of care and resources available across the 17 Spanish regions for the management of cognitive impairment and dementia in order to identify improvement areas, as well as to provide a list of recommendations.Methods
The working group consisted of an Advisory Committee of 5 national experts and a Committee of Experts from each region made up of professionals in the field of Neurology, Geriatrics, Psychiatry, and Primary Care, as well as representatives of Family Associations of People with Alzheimer's and other dementias. The Expert Committee of each region held meetings in which the current situation of care was reviewed.Results
Plans available in Spain for dementia management are mostly obsolete or have not been implemented. Prevention and early detection activities are generally not carried out. There is great variability of care process that patients must follow for the diagnosis, treatment, and follow-up of the disease, and not all diagnostic test are available in different regions. In general, resources are considered scarce and unknown.Conclusions
The Mapa de la enfermedad de Alzheimer y otras demencias en España study has been able to detect the main points that require changing n the management, organisation, and coordination of resources, such as information and training of the personnel involved. Furthermore, the study has revealed that, in Spain, the necessary conditions are in place in Spain, such as the availability and capacity of professionals involved, as well as there being the potential diagnostic and health care resources to address this room for improvement through the approval and development of a National Alzheimer's Plan, supported by a deep and truthful political commitment, which will be the ideal framework for the development of these possibilities. 相似文献18.

Tinea capitis is an infection caused by dermatophytes of the genera Microsporum and Trichophyton, and constitutes a major health problem in Argentina. The aim of the present study was to find out the incidence of those etiological agents and the therapeutic response in patients attending a High-Complexity Paediatric Hospital within a two-year period. A total of 98 tinea capitis were diagnosed, 13 of which were Celsus kerion. Microsporum canis was isolated in 61.28%. The range of values for minimum inhibitory concentrations were >32, 0,06–4; <0,015–2; <0,015–0.25; 0.13–8; 0.06–128 μg/mL for fluconazole itraconazole, voriconazole, terbinafine, ketoconazole and griseofulvin, respectively. 相似文献

IntroductionSpanish National Health Surveys do not establish synergistic relations between variables. The purpose of this study was to perform a deeper historical analysis of body mass index (BMI) and its relation to other parameters included in the questionnaire for children.Material and methodsData from interviews conducted (between 1987 and 2006) to parents and guardians of schoolchildren aged 9-15 years were analyzed. Height and weight reported by parents were selected and used to calculate BMI. Subjects were stratified by age, gender, time spent sleeping and watching television and, finally, frequency of physical activity. The historical trend of BMI and its dependence on the above factors were analyzed using ANOVA tests.Results and conclusionsSignificant weight and height increases were seen, which were more marked in boys aged 12 to 15 years. Influence of physical activity on BMI was shown, but decreased (P < .001) as exercise time increased. By contrast, BMI increased (P < .001) as time spent watching television increased. On the other hand, the role of sleep as modulator of body size was confirmed, since schoolchildren aged 9-11 years who slept over 9 h had lower BMIs (P < .001). In subjects aged 12 to 15, BMI decreased (P < .001) from 6 h of sleep. 相似文献
