La biblioteca en el espacio ciudadano. Reflexiones a partir de la investigación española sobre el usuario de la información, 2005-2019
2021
Los últimos datos sobre el escaso uso de las bibliotecas españolas cuestionan la utilidad de este servicio en la cotidianidad ciudadana. Paralelamente, un movimiento dentro de la Biblioteconomía y Documentación que habla de la biblioteca social, participativa o del bien común, busca ampliar el espacio ciudadano que ésta ocupa. Este trabajo se centra en las implicaciones que para este propósito tienen las últimas investigaciones españolas sobre usuarios de la información. Primero, los datos revelan la escasa participación de los profesionales en estas investigaciones. Segundo, abundan aquellas que se centran en la evaluación de unidades de información, pero escasean las dirigidas a obtener d…
Ortodontiskās ārstēšanas nepieciešamības indeksa (IONT) izmantošana minētajiem Latvijas iedzīvotājiem
2020
Priekšvēsture: Ortodontiskos indeksus visā pasaulē izmanto, lai noteiktu pacientu ortodontisko stāvokli. Visā pasaulē netiek izmantots vienots standarts. Viens no populārākajiem ortodontiskajiem indeksiem ir ortodontiskās ārstēšanas nepieciešamības indekss (IOTN) un Engla klasifikācija (Han & Davidson, 2001).Ortodontiskie indeksi palīdz noteikt nepareizu sakodienu un nosaka pacienta ortodontisko stāvokli. Tas nozīmē, ka ārstēšanā prioritāte tiek piešķirta tiem, kam tā vispirms nepieciešama, un tas palīdz pamatoti un taisnīgi sadalīt resursus (Tang, 1993).Papildus šiem aspektiem, kas saistīti ar cilvēku nepareiza sakodiena izvērtējumu, tie palīdz arī iz…
Pulmonary actinomycosis. Fine needle aspiration diagnostic.
2011
Atículo publicado en: Invest Clin 52(4): 356 - 360, 2011 Se presentan 4 casos de actinomicosis pulmonar en pacientes mayores de 55 años, 2 de ellos con enfermedad pulmonar obstructiva crónica (EPOC), que mostraron un aumento de la tos productiva, episodios de disnea, hemoptisis y fiebre de larga evolución. En las radiografías de tórax de rutina se observaban imágenes segmentarias de consolidación aérea, sugestivas de cuadros neumónicos no resueltos o neoplasia. La tomografía axial computarizada (TAC) mostró hallazgos similares a los anteriores. Los cultivos de esputo y las pruebas de Mantoux fueron repetidamente negativos. Debido a la mala evolución de los pacientes y a los hallazgos radiol…
Las dificultades para la educación integradora desde la perspectiva de futuros maestros de inglés
2009
This article presents and analyses the findings of a qualitative study about the perceptions expressed by prospective primary teachers of English about integration and response to special educational needs in the mainstream. The analysis of the data, obtained in the course of the practice teaching period of their course, evidences their ideas on integrative education; besides, a frequent lack of experiences of genuine integrative practices in such a critical period of professional preparation is identified. El presente artículo presenta y analiza los hallazgos de un estudio de naturaleza cualitativa sobre las percepciones que expresan futuros maestros especialistas de inglés en el transcurs…
Low-dose rivaroxaban plus aspirin in older patients with peripheral artery disease undergoing acute limb revascularization: insights from the VOYAGER…
2021
Abstract Aims In this secondary analysis of the VOYAGER trial, rivaroxaban 2.5 mg twice/day plus aspirin 100 mg/day was assessed in older adults. Advanced age is associated with elevated bleeding risk and unfavourable net benefit for dual antiplatelet therapy in chronic coronary artery disease. The risk–benefit of low-dose rivaroxaban in patients ≥75 years with peripheral artery disease (PAD) after lower extremity revascularization (LER) has not been described. Methods and results The primary endpoint was a composite of acute limb ischaemia, major amputation, myocardial infarction, ischaemic stroke, or cardiovascular death. The principal safety outcome was thrombolysis in myocardial infarct…
Thyroid neoplasms: surgical and cyto-histopathological connections on a six year cases study
2018
This study aims to evaluate the percentage of cyto-histologic correlation in patients with a thyroid disease documented through clinical-instrumental, cytological (FNAB), histological and surgical examinations. The purpose of this study is also to determine the percentage of disease incidence and evaluating any surgical indication in relation to biological behavior (benign, malignant or indeterminate lesions, occult carcinomas), sex, and age.Almost all of thyroid neoplasms is manifested through thyroid nodule. Therefore, clinical evidence of the thyroid nodule analysis is primarily related to the need to exclude malignant pathology or carcinoma of the thyroid, present in 4-6.5% of cases.The…
Fine-needle biopsy of parathyroid adenomas
1986
High-resolution real-time sonography was performed in 15 cases of clinically and chemically suspected primary hyperparathyroidism and in 20 patients with different thyroid nodules. The suspected enlarged parathyroid glands and the thyroid nodules were percutaneously punctured under sonographic control. Concentrations of parathyroid hormone, human thyroglobulin, and human calcitonin were measured in the aspirate, and immunocytology was performed. The mean concentration of the aspirated parathyroid hormone in the parathyroid glands was 4,013.6 pmol/l +/- 4,519 (SD) as compared with 14.9 pmol/l +/- 8.7 in the thyroid nodules. Thyroglobulin was present in the aspirated fluid of parathyroid aden…
Comparison of the yield from two faecal immunochemical tests at identical cutoff concentrations – a randomized trial in Latvia
2016
OBJECTIVE We have compared the performance of two faecal immunochemical tests (FIT) in an average-risk population. MATERIALS AND METHODS Altogether, 10 000 individuals aged 50-74 were selected randomly from the population of Latvia in 2011 and assigned randomly either to OC-Sensor or to FOB Gold single-time testing. Positivity of the test, frequency of colonic lesions, number needed to screen (NNscreen) and scope for the detection of an advanced neoplasm (cancer and advanced adenoma) were compared between the tests using the same cutoff concentrations in µg/g faeces. Confidence intervals (CIs) at 95% were calculated. RESULTS Positivity with the cutoff set at 10 µg/g faeces was 12.8% (95% CI…
Standardized long-term follow-up after endoscopic resection of large, nonpedunculated colorectal lesions: a prospective two-center study.
2014
Endoscopic removal of large, nonpedunculated colorectal lesions is challenging. Long-term outcome data based on standardized protocols, including detailed inspection of the resection site, are scarce. The aims of the present study were to evaluate the safety and efficacy of endoscopic resection (ER) of large, nonpedunculated lesions (LNLs;20 mm) and to assess the long-term recurrence rate afterward.A total of 243 consecutive patients (141 men, 102 women) with 252 adenomas (20 mm) was followed up using a standardized protocol after complete ER. After endoscopic treatment, the patients received standardized follow-up examinations after 3-6 months and 12 months. The postpolypectomy scar was re…
Immunoperoxidase Staining of Fine-Needle Aspiration Biopsies of Renal Cell Carcinoma Using Tumor-Specific Monoclonal Antibody
1987
In 30 nephrectomy specimens, fine needle aspiration biopsies (FNAB) were performed both in the tumor and in the macroscopically normal part of the kidney: 18 were well differentiated renal cell carcinoma (RCC), 6 were moderately differentiated RCC, 4 were poorly differentiated RCC, and 2 were oncocytomas. FNAB was also performed in a bone metastasis of RCC. FNAB materials were stained using the immunoperoxidase method with RCC-specific monoclonal antibody and were compared with the staining of frozen sections. In all cases where tumor-antigen expression could be demonstrated in the frozen sections, a FNAB had already proven positive. There were only 2 false-negative cases where sufficient c…
