Free-living energy expenditure (EE) was assessed in 37 young pregnant Gambian women at the 12th (n = 11, 53.5 +/- 1.7 kg), 24th (n = 14, 54.7 +/- 2.1 kg), and 36th (n = 12, 65.0 +/- 2.6 kg) wk of pregnancy and was compared with nonpregnant nonlactating (NPNL) control women (n = 12, 50.3 +/- 1.6 kg). The following two methods were used to assess EE: 1) the heart rate (HR) method using individual regression lines (HR vs EE) established at different activity levels in a respiration chamber and 2) the doubly labeled water (2H2(18)O) method in a subgroup of 25 pregnant and 7 control women. With the HR method the EE during the agricultural rainy season was found to be 2,408 +/- 87, 2,293 +/- 122, and 2,782 +/- 130 kcal/day at 12, 24, and 36 wk of gestation and were not significantly different from the control group (2,502 +/- 133 kcal/day). These findings were confirmed by the 2H2(18)O measurements, which failed to show any effect of pregnancy on EE. Expressed per unit body weight, the free-living EE was found to be lower (P less than 0.01 with 2H2(18)O method) at 36 wk of gestation than in the NPNL group. It is concluded that, in these Gambian women, energy-sparing mechanisms that contribute to meet the additional energy stress of gestation are operating during pregnancy (e.g., diminished spontaneous physical activity).

El progressiu increment del flux migratori en els darrers anys a Catalunya genera un major percentatge de dones en estat fèrtil que requereixen d’una atenció vinculada a la seva salut reproductiva. D’aquesta manera, els professionals sanitaris es veuen sotmesos a treballar sota una diversitat cultural que moltes vegades genera un “xoc intercultural” dificultant la relació assistencial entre professional i usuari. Per aquest motiu, el següent estudi pretén donar una aproximació de la influència cultural de la dona immigrant (marroquina i subsahariana) en quatre àmbits: embaràs, part, post-part i maternitat.Hipòtesis: S’identifiquen necessitats bàsiques assistencials no resoltes satisfactòriament en el grup de dones immigrants (marroquines i subsaharianes) en el període del part, puerperi immediat i intermedi, a més d’un impacte intercultural associat.Objectiu principal: Conèixer les vivències, percepcions i conductes de les dones marroquines i subsaharianes en l’embaràs, el part, el post-part, la maternitat dins el seu marc cultural i com influeixen en l’atenció sanitària del nostre país.Material i mètodes: S’ha realitzat un estudi de disseny mixt. Per una banda s’ha disposat d’una metodologia qualitativa descriptiva que utilitza la teoria fonamentada “Grounded Theory” com a instrument metodològic, i per l’altra, s’ha optat per una metodologia quantitativa per analitzar les dades clíniques i epidemiològiques de gestants immigrants que havien donat a llum al Servei d’Obstetrícia-Sala de Parts de l’Hospital Sta. Caterina (Girona), durant el període comprès entre el mes de novembre de 2012 i gener de 2013.La recollida de dades s’ha realitzat sota una entrevista semiestructurada i una observació participant com a instruments qualitatius, i el suport del “carnet de l’embaràs” i la “història obstètrica” de cada dona per elaborar l’estudi quantitatiu. Pel que fa a l’anàlisi de les dades en l’estudi qualitatiu s’ha seguit el procés analític plantejat per la Teoria fonamentada i en el cas de l’estudi quantitatiu, s’ha comptatamb el suport d’una tesi doctoral per comparar els resultats amb els de les dones autòctones, dels quals fa referència la tesi.Resultats: En l’estudi qualitatiu, s’han trobat especificitats culturals en relació a la percepció del part, desenvolupament del part ( a nivell conductual), implicació en el post-part, valoració de l’atenció sanitària rebuda i el concepte de maternitat. Pel que fa a l’estudi quantitatiu comparatiu, s’han indentificat diferències entre el col·lectiu de la mostra estudiada i les dones autòctones referent als antecedents obstètrics i paritat, al control gestacional i al desenvolupament del part ( a nivell fisiològic)

Tradicionalment hem pensat que la fe és fruit d"una elecció personal. Tanmateix, si el fet religiós és universal, no podria ser que la nostra biologia l"estigués també propiciant?

OBJECTIVE: To describe prevalence, prenatal diagnosis and epidemiology of congenital hydronephrosis (CH) in Europe. MATERIAL AND METHOD: Data from a large European database for surveillance of congenital malformations (EUROCAT). The 20 participating registries are all based on multiple sources of information and include information about livebirths, fetal deaths with gestational age >or=20 weeks and terminations of pregnancy after prenatal diagnosis of malformations. Included were all cases with CH and born 1995-2004. RESULTS: There were 3648 cases with CH giving an overall prevalence of 11.5 cases per 10,000 births. The large majority of cases were livebirths (3506, 96% of total) and only 17 cases were fetal deaths and 120 were terminations of pregnancy. Almost all livebirths were alive 1 week after birth. Boys accounted for 72% of all cases. A high proportion of the cases (86%) had an isolated renal malformation. There were large regional differences in prevalence of CH ranging from 2 to 29 per 10,000 births. There was little regional variation in the prevalence of postnatally diagnosed cases while there were large regional differences in prevalence of prenatally diagnosed cases. CONCLUSION: Cases with CH are mainly livebirths, boys and survive the first week after birth. The large difference in prevalence seems to be related to the availability of prenatal screening in the region. The impact of over-diagnosis and potential over-treatment in regions with high prevalence or under-diagnosis with implications for renal function later in life in regions with low prevalence needs further investigation.

Digital art interfaces presents cognitiveparadigms that deals with the recognition of the symbols and representations through interaction.What is presented in this paper is anapproximation of the bodily experience in that particular scenario and a new proposal which has the aim to contribute more ideas and criteria in the analysis of the learning process of aparticipant discovering an interactive space or interface. For that I propose a first new approach where metaphorically I tried to extrapolate the stages of the psychology of development stated byJean Piaget in the interface design domain.

We report an experiment where participants observed an attack on their virtual body as experienced in an immersive virtual reality (IVR) system. Participants sat by a table with their right hand resting upon it. In IVR, they saw a virtual table that was registered with the real one, and they had a virtual body that substituted their real body seen from a first person perspective. The virtual right hand was collocated with their real right hand. Event-related brain potentials were recorded in two conditions, one where the participant"s virtual hand was attacked with a knife and a control condition where the knife only struck the virtual table. Significantly greater P450 potentials were obtained in the attack condition confirming our expectations that participants had a strong illusion of the virtual hand being their own, which was also strongly supported by questionnaire responses. Higher levels of subjective virtual hand ownership correlated with larger P450 amplitudes. Mu-rhythm event-related desynchronization in the motor cortex and readiness potential (C3C4) negativity were clearly observed when the virtual hand was threatened as would be expected, if the real hand was threatened and the participant tried to avoid harm. Our results support the idea that event-related potentials may provide a promising non-subjective measure of virtual embodiment. They also support previous experiments on pain observation and are placed into context of similar experiments and studies of body perception and body ownership within cognitive neuroscience.

Meckel-Gruber Syndrome is a rare autosomal recessive lethal ciliopathy characterized by the triad of cystic renal dysplasia, occipital encephalocele and postaxial polydactyly. We present the largest population-based epidemiological study to date using data provided by the European Surveillance of Congenital Anomalies (EUROCAT) network. The study population consisted of 191 cases of MKS identified between January 1990 and December 2011 in 34 European registries. The mean prevalence was 2.6 per 100 000 births in a subset of registries with good ascertainment. The prevalence was stable over time, but regional differences were observed. There were 145 (75.9%) terminations of pregnancy after prenatal diagnosis, 13 (6.8%) fetal deaths, 33 (17.3%) live births. In addition to cystic kidneys (97.7%), encephalocele (83.8%) and polydactyly (87.3%), frequent features include other central nervous system anomalies (51.4%), fibrotic/cystic changes of the liver (65.5% of cases with post mortem examination) and orofacial clefts (31.8%). Various other anomalies were present in 64 (37%) patients. As nowadays most patients are detected very early in pregnancy when liver or kidney changes may not yet be developed or may be difficult to assess, none of the anomalies should be considered obligatory for the diagnosis. Most cases (90.2%) are diagnosed prenatally at 14.3±2.6 (range 11-36) gestational weeks and pregnancies are mainly terminated, reducing the number of LB to one-fifth of the total prevalence rate. Early diagnosis is important for timely counseling of affected couples regarding the option of pregnancy termination and prenatal genetic testing in future pregnancies.

Introducción: La incidencia de la presentación fetal podálica en España es del 3,8%. La moxibustión es parte integral de la milenaria medicina tradicional china. La técnica consiste en la colocación de un palillo incandescente de Artemisia vulgaris a unos pocos centímetros del punto de acupuntura Zhiyin (punto 67 del meridiano de vejiga, ubicado en la base externa de la uña del quinto dedo del pie). Los objetivos son: 1. Conocer el porcentaje de fetos que han rotado a cefálica mediante la moxibustión en gestantes que presenten una malposición fetal a partir de las 32 semanas de embarazo; 2. Identificar las complicaciones materno-fetales en la aplicación de la técnica. Sujetos: Se estudiaron 18 gestantes de más de 32 semanas de embarazo. Material y métodos: Mediante un estudio descriptivo de intervención, analizamos el porcentaje de fetos que rotaron a presentación cefálica. Resultados: Quince gestantes (83,9%) realizaron el tratamiento adecuadamente y las 3 restantes (16,7%) lo realizaron de manera ocasional y terminaron con una cesárea electiva por nalgas. Conclusiones: Parece razonable concluir que el cumplimiento del tratamiento influye en el tipo de parto (χ2= 12,600; gl= 1; p= 0,000), aunque no modifica el Apgar del recién nacido. Esta técnica se presenta como una alternativa económica, segura, sencilla y práctica para la versión fetal de la presentación podálica.

Tutkimus on perheyrittäjyystutkimusta, se käsittelee perheyrityksessä tapahtunutta sukupolvenvaihdosta sekä siihen liittyvää luopumisen prosessia. Poikkitieteellisenä lähestymistapana käytetään sosiologisia ja psykologisia katsantokantoja identiteetin rakentumisesta ja sen muuttumisesta. Luopumiskäsitettä lähestytään perheyrittäjän identiteetin rakentumisen ja muuttumisen kautta. Tutkimus etsii vastausta neljään kysymykseen: 1. Millainen on perheyrittäjän identiteetti? 2. Miten perheyrityksen sukupolvenvaihdos vaikuttaa identiteettiin? 3. Mitä luopuminen tarkoittaa sukupolvenvaihdoksessa? 4. Mitä sukupolvenvaihdoksessa todellisuudessa tapahtuu? Tutkimuksessa paneudutaan luopujan ja jatkajan näkökulmiin, joita tarkastellaan elämänkertatarinoiden avulla. Tutkimuksen aineisto koostuu viidestä yrityksestä, joissa jollakin tasolla on sukupolvenvaihdos toteutettu. Tutkimuksessa on haastateltu kolmeatoista henkilöä. Tutkimuksen perusteella voidaan todeta, että perheyrittäjän identiteetti on hyvin kompleksinen ja vaikeasti lähestyttävä asia. Perheyrittäjän persoona on vahva ja perhe sekä yritys vaikuttavat oleellisesti sen muotoutumiseen. Individuaalisuus jää usein familistisen näkemyksen jalkoihin. Sukupolvenvaihdos vaikutti sekä luopujan että jatkajan identiteettiin ratkaisevasti. Luopujat kohtasivat kriisin miettiessään yrityksensä tulevaisuutta ja moni jatkaja puolestaan muutti elämäänsä radikaalisti siirtyessään perheyrityksen jatkajaksi. Työstä luopuminen osoittautui tutkimuksessa kriittisimmäksi tekijäksi, etenkin luopujien näkökulmasta katsottuna. Jatkajille se merkitsi oman jo mahdollisen muun uran ja työpaikan vaihtumista perheyritykseen. Luopujille se teoriassa tarkoitti eläkkeelle siirtymistä. Tutkituissa yrityksissä kukaan luopujista ei kuitenkaan ole lopettanut työn tekoa. He ovat jokapäiväinen näky yrityksessä ja enemmän tai vähemmän aktiivisesti mukana yrityksen toiminnoissa. Tämä aiheuttaa sukupolvien yhteentörmäystä ja konflikteja, tämä seikka vie paljon energiaa yrityksessä tehtävältä työltä. Työ on yrittäjälle erittäin vahva ja merkitsevä identiteetin perusta, jonka muuttaminen tai siitä luopuminen on vaikeaa.
