Video-assisted thoracoscopic resection of a small pulmonary nodule after computed tomography-guided localization with a hook-wire system. Experience in 45 consecutive patients.

BACKGROUND: This study is a single-institution validation of video-assisted thoracoscopic (VATS) resection of a small solitary pulmonary nodule (SPN) previously localized by a CT-guided hook-wire system in a consecutive series of 45 patients. METHODS: The records of all patients undergoing VATS resection for SPN preoperatively localized by CT-guided a hook-wire system from January 2002 to December 2004 were assessed with respect to failure to localize the lesion by the hook-wire system, conversion thoracotomy rate, duration of operation, postoperative complications, and histology of SPN. RESULTS: Forty-five patients underwent 49 VATS resections, with simultaneous bilateral SPN resection performed in 4. Preoperative CT-guided hook-wire localization failed in two patients (4%). Conversion thoracotomy was necessary in two patients (4%) because it was not possible to resect the lesion by a VATS approach. The average operative time was 50 min. Postoperative complications occurred in 3 patients (6%), one hemothorax and two pneumonia. The mean hospital stay was 5 days (range: 2-18 days). Histological assessment revealed inflammatory disease in 17 patients (38%), metastasis in 17 (38%), non-small-cell lung cancer (NSCLC) in 4 (9%), lymphoma in 3 (6%), interstitial fibrosis in 2 (4%), histiocytoma in one (2%), and hamartoma in one (2%). CONCLUSIONS: Histological analysis of resected SPN revealed unexpected malignant disease in more than 50% of the patients indicating that histological clarification of SPN seems warranted. Video-assisted thoracoscopic resection of SPN previously localized by a CT-guided hook-wire system is related to a low conversion thoracotomy rate, a short operation time, and few postoperative complications, and it is well suited for the clarification of SPN.

Graphoepitaxy of CeO2 on MgO and its application to the fabrication of 45° grain boundary Josephson junctions of YBa2Cu3O7-x

We communicate a detailed study of the epitaxial growth of CeO2 on MgO. The key feature of the growth is the dependence of the in¿plane orientation of the CeO2 epitaxial layer on the MgO surface morphology. Atomic force microscopic (AFM) measurements, x¿ray analyses, as well as high¿resolution transmission electron microscopy (HRTEM) investigations reveal that on rough substrates a cube¿on¿cube growth of CeO2 on MgO occurs while on smooth substrates the CeO2 unit cell is rotated around the surface normal by 45° with respect to the MgO unit cell when the deposition rate is low (~0.3 Å/s) during the first stages of growth. This growth mechanism can be used for a defined fabrication of 45° grain boundaries in the CeO2 layer by controlling the surface roughness of the MgO substrate. This report demonstrates that these 45° grain boundaries may be used to fabricate YBa2Cu3O7¿x Josephson junctions.

Risk of a Down syndrome live birth in women 45 years of age and older.

OBJECTIVES: To determine the risk of a Down syndrome (DS) live birth for women 45 years of age and over. METHODS: A meta-analysis of data from five published articles, 13 EUROCAT congenital anomaly population registers and two unpublished sources. RESULTS: Information was available on the number of DS live births occurring amongst 13,745 live births to women 45 years of age and over. Information was also available on DS pregnancies diagnosed prenatally that were subsequently terminated. These pregnancies were adjusted for expected fetal loss to estimate the number of live births that would have occurred in the absence of prenatal diagnoses, when a total of 471 DS live births were estimated to have occurred. The risk of a DS birth did not increase for women 45 years of age and over. The average risk was 34 per 1000 births (95% CI: 31-37). CONCLUSION: The risk of a DS live birth for women 45 years of age and over is considerably lower than has often been previously assumed. The most likely explanation is that women of this age are more likely to miscarry DS pregnancies than younger mothers.

Reseña de la tesis doctoral: Educación no formal y adoctrinamiento infantil en la "España azul". Flechas y pelayos (1939-45)

Constituye hoy una preocupación social e intelectual que atañe particularmente al profesorado, la identificación de los mecanismos a través de los cuales se transmiten y se afianzan los sistemas de valores en la infancia y en la juventud. También interesa de manera especial, a tenor de la frecuencia de su uso político y público, la definición y construcción de las identidades y, muy en concreto, de las nacionales. En este sentido, buena parte de las investigaciones actuales indica que, a partir de los últimos decenios del siglo XX, la transmisión y construcción de valores e identidades se comunican y se construyen prioritariamente a través de las redes mediática

Decreased pyramidal neuron size in Brodmann areas 44 and 45 in patients with autism.

Autism is a neurodevelopmental disorder characterized by deficits in social interaction and social communication, as well as by the presence of repetitive and stereotyped behaviors and interests. Brodmann areas 44 and 45 in the inferior frontal cortex, which are involved in language processing, imitation function, and sociality processing networks, have been implicated in this complex disorder. Using a stereologic approach, this study aims to explore the presence of neuropathological differences in areas 44 and 45 in patients with autism compared to age- and hemisphere-matched controls. Based on previous evidence in the fusiform gyrus, we expected to find a decrease in the number and size of pyramidal neurons as well as an increase in volume of layers III, V, and VI in patients with autism. We observed significantly smaller pyramidal neurons in patients with autism compared to controls, although there was no difference in pyramidal neuron numbers or layer volumes. The reduced pyramidal neuron size suggests that a certain degree of dysfunction of areas 44 and 45 plays a role in the pathology of autism. Our results also support previous studies that have shown specific cellular neuropathology in autism with regionally specific reduction in neuron size, and provide further evidence for the possible involvement of the mirror neuron system, as well as impairment of neuronal networks relevant to communication and social behaviors, in this disorder.

Iowa Influenza Surveillance Network: Weekly Activity Report Week 45, November 14, 2015

The Iowa Influenza Surveillance Network (IISN) was established in 2004, though surveillance has been conducted at the Iowa Department of Public Health. Schools and long-term care facilities report data weekly into a Web-based reporting system. Schools report the number of students absent due to illness and the total enrolled. Long-term care facilities report cases of influenza and vaccination status of each case. Both passively report outbreaks of illness, including influenza, to IDPH.

L'atur de llarga durada de les dones majors de 45 anys a Catalunya: una anàlisi exploratòria tenint en compte la classe social i la divisió sexual del treball

This article provides an in-depth study of long-term female unemployment in Catalonia.Long-term unemployment statistics reveal which social groups are most likely to experience difficulty re-entering the labour market. In this case, we found that women are mainly affected by this type of labour exclusion, in particular poorly qualified, working-class women who are aged over 45 and with family responsibilities.The article aims to explore how the overlapping of factors such as gender, age, social class, origin and the division of work based on gender are related to long-term female unemployment. Moreover, we were able to detect which conceptual tools provide us with the production/reproduction paradigm so as to be able to analyse the future of female unemployment. The methodology we used combines quantitative and qualitative approaches. On the one hand, the analysis of secondary statistical data focusing on Catalonia is useful in understanding the situation from a macro-social perspective. On the other hand, an exploratory discussion group enables us to investigate social imaginary practises among unemployed working class women aged over 45. This discussion group was held in Igualada -capital of the Anoia region - an area of Catalonia deeply affected by unemployment in the current economic crisis.

Característiques epidemiològiques i topogràfiques de les lesions patides per un col•lectiu d’esportistes d’alt rendiment durant un període de 45 mesos

En els darrers anys s’han publicat diversos articles que descriuen l’epidemiologia de les malalties i lesions patides per persones que practiquen diferents esports. Aquestes investigacions s’han fet a partir de les dades reco· llides durant períodes d’entrenament de diversa durada o bé durant unes competicions concretes, com poden ser uns Jocs Olímpics. L’objectiu del present estudi va ser el de recollir i analitzar les dades epidemiològiques de les lesions patides per una població d’esportistes del nostre país, durant un període de temps determinat que inclou tant el temps d’entrenament com el de competició. La informació va ser recollida en el servei mèdic d’un centre d’entrenament esportiu, a partir de les dades de les visites mèdiques recollides en l’historial clínic de cada espor· tista. Es van revisar 16.925 visites mèdiques, realitzades en 45 mesos, d’esportistes d’ambdós gèneres i de 29 esports diferents. Les variables que es van analitzar van ser el tipus de lesió, les circumstàncies de producció de la lesió i la topografia de la lesió.Es va veure que el 90 % de totes les lesions es van produir durant l’entrenament. Les més freqüents van ser les agudes (75 %). Les parts del cos més afectades van ser el genoll (17 %), el turmell (12 %), el peu (11%), la cintura escapular (10 %) i la regió lumbar (10 %).
