Urban green spaces and childhood leukemia incidence: A population-based case-control study in Madrid.
2021
Abstract Background Childhood leukemia is the most common childhood cancer. To date, few risk factors related to predisposition have been identified; therefore, new hypotheses should be considered. Objective To explore the possible relationship of residential proximity to urban green spaces on childhood leukemia. Methods We conducted a population-based case control study in the metropolitan area of Madrid from 2000 to 2015. It included 383 incident cases and 1935 controls, individually matched by birth year, sex and area of residence. Using the geographical coordinates of the participants’ home residences, we built a proxy for exposure with four distances (250 m, 500 m, 750 m and 1 km) to u…
Accessory submaxillary gland : two new case reports and a literature review
2020
Background The accessory submaxillary gland is a very uncommon anatomical variant, and incidence in the general population has not yet been quantified. The presence of pathology in these glands is rarer still, thus often going unnoticed. Material and methods We describe two accessory submaxillary gland cases, one asymptomatic and the other with chronic sialadenitis in the main and accessory gland caused by sialolithiasis. Although our diagnosis was by computerized tomography, magnetic resonance sialography is helpful to understand and describe this entity with greater precision. Results The first case report is an incidental finding and no intervention was required. However, case report num…
P046 Occupational exposures and gastric cancer risk in the MCC-spain case-control study
2016
Objective To explore the relationship between gastric cancer (GC) and occupational exposures. Methods A total of 382 incident GC cases and 2,846 randomly selected population controls with occupational information were included from the MCC-Spain study, a population-based multicase-control study. Occupation was coded according to the Spanish National Classification of Occupations 1994. Occupational exposures were assessed by the MatEmEsp Job Exposure Matrix. ORs and their 95% confidence intervals (CI) were estimated by unconditional logistic regression adjusting for matching variables and education. Results In men, a statistically significant increased risk of GC, was found for ‘Employed ski…
Case Control Study on Childhood Leukemia in Lower Saxony, Germany
1996
In two municipalities in Lower Saxony statistically valid clusters were observed, which attracted great public interest. Committees were set up to initiate a large variety of on-the-spot-investigations. Finally, it was decided to conduct a case control study throughout Lower Saxony to explore potential risk factors which might explain the observed clusters. A limited number of already established and currently discussed hypotheses was chosen for investigation. The study was based on patients registrated at the German Children's Cancer Registry (GCCR). For each child with leukemia diseased between 1988 and 1993 two population-based controls (local and state controls) and one tumour control w…
Prevalence of lumbosacral radiculopathy in two Sicilian municipalities
2009
Objectives - As part of a door-to-door survey of neurologic diseases, we investigated the prevalence of lumbosacral radiculopathy (LR) in two Sicilian municipalities (N = 14,540, as of November 1, 1987). Material & methods - During phase 1, we administered a brief screening instrument to subjects in the study population. In phase 2, study neurologists using specified diagnostic criteria investigated those subjects who screened positive. Our case finding was restricted to subjects who manifested symptoms of LR in the six months preceding the prevalence day. Results - We found 143 subjects affected by LR (112 definite, 31 possible) yielding a crude prevalence of 9.8 cases per 1,000 population…
Technology-Supported Educational Innovations in Finland and Hong Kong: A Tale of Two Systems
2005
The paper presents a comparison of case studies about innovative ICT-supported pedagogical practices in two educational systems, namely Finland and Hong Kong. The two systems were selected for this in-depth comparison for three main reasons. First, Finland and Hong Kong performed well in several international comparative studies of educational achievement. Second, the case studies collected via the SITES Module 2 indicated rather different profiles between Finnish and Hong Kong schools in terms of ICT infrastructure and pedagogical practices. Third, further analysis of the case studies data indicated differences in emergent pedagogical characteristics between the cases collected in Asia and…
Geneza Case Method i jej wpływ na kształt amerykańskiej filozofii prawa
2018
Artykuł omawia Case Method – dominującą metodę edukacyjną stosowaną w amerykańskich szkołach prawa, która polega na nauczaniu prawa poprzez analizę orzeczeń sądowych, stworzoną w latach 70. XIX w. przez Christophusa Collumbusa Langdella. Langdell postrzegał prawo jako naukę, podobną do fizyki czy chemii, a więc jako uporządkowany system obiektywnej wiedzy. Stworzona przez niego metoda nauczania służyć miała przygotowaniu osób zajmujących się prawem w sposób naukowy. W artykule przedstawiona została koncepcja prawa Langdella, oraz wpływ, jaki jego metoda nauczania wywarła na nurty amerykańskiej filozofii prawa – klasyczną jurysprudencję oraz realizm prawniczy.
Developing Peer Corrective Skills in Business Letter Writing in English as a Foreign Language
2019
Peer corrective feedback (PCF) implementation is a topical issue in writing skills development at tertiary level. Those researchers who explore the application of PCF in higher education (e.g. Liu and Sadler, 2003; Hyland, K. and Hyland, F., 2006) admit that students face difficulties in providing qualitative feedback that determines the effectiveness of this teaching tool. Therefore, the goal of this paper was to investigate what actions could be taken in order to develop students’ PCF skills and, consequently, foster the quality of PCF. The primary research method was a case study in which the participants were 24 second-year undergraduates majoring in English as a Foreign Language (EFL…
Gestion de casos en pacientes con cronicidad compleja y con necesidades al final de la vida. Análisis de los resultados
2019
Introduction: Los programas de gestion de casos (GC) surgieron como un nuevo enfoque en la atencion de personas con problemas de salud complejos con el objetivo de mejorar la calidad de vida y de procurar por la eficiencia en el uso de recursos. Theory/methods: Desde 2010, en el Departament de Salud Valencia-LaFe se desarrolla la GC sobre dos grupos de poblacion: pacientes con cronicidad compleja y con necesidades paliativas (oncologicos y no oncologicos). En ambos casos, la atencion se caracteriza por desarrollar intervenciones de seguimiento programado y continuo, y por la posibilidad de proporcionar atencion avanzada en domicilio ante la identificacion temprana de necesidades y exacerb…
Unique clockwork in photoreceptor of rat
2010
In mammals, the retina contains a clock system that oscillates independently of the master clock in the suprachiasmatic nucleus and allows the retina to anticipate and to adapt to the sustained daily changes in ambient illumination. Using a combination of laser capture micro-dissection and quantitative PCR in the present study, the clockwork of mammalian photoreceptors has been recorded. The transcript amounts of the core clock genes Clock, Bmal1, Period1 (Per1), Per3, Cryptochrome2, and Casein kinase Ie in photoreceptors of rat retina have been found to undergo daily changes. Clock and Bmal1 peak with Per1 and Per3 around dark onset, whereas Casein kinase Ie and Cryptochrome2 peak at night…
