It is known that breast-fed babies have better sleep patterns and a better entrained sleep/wake cycle than bottle-fed babies (adapted formula). To compare the circadian rhythm of 6-sulfatoxymelatonin (aMT6s)--the metabolite of melatonin excreted in the urine--in urine of bottle-fed and breast-fed children, and relate it to the circadian rhythm of tryptophan in breast milk, also evaluating the possible effects on the baby's night-time rest. 16 infants of 12 weeks of age were studied, divided into two groups depending on their exclusively natural or artificial feeding. The circadian rhythm of 6-sulfatoxymelatonin in urine was measured for the two groups of infants and for the breast-feeding mothers. In the breast milk, the circadian rhythm of the amino acid tryptophan was measured. The rest of the infants was tested by wrist actimeters for a week and the...

Using an automated reticulocyte counter, we analyzed immature reticulocyte fraction (IRF), mean reticulocyte volume (MRV) and mean fluorescence index (MFI) in peripheral blood samples from healthy donors (n ¼ 30), patients diagnosed with myelodysplastic syndromes (MDS, n ¼ 35), with megaloblastic anemia (MA, n ¼ 10) and with non-megaloblastic macrocytic anemias (NMMA, n ¼ 30). Macrocytic anemias due to ineffective erythropoiesis (MA and MDS) showed reticulocytes skewed to a more immature fraction. Therefore, they have a larger volume and a greater RNA content than healthy controls. Interestingly, reticulocytes in both low and high risk MDS are significantly larger (127.3 vs. 118.3 fl, P < 0.01) and have a greater RNA content (MFI 20.5 vs. 12.9, P < 0.01 and IRF 22.5 vs. 9.1%, P < 0.01) than NMMA patients. We conclude that measurement of reticulocyte maturation parameters may be a very useful tool in the differential diagnosis of macrocytic anemia. The presence of extremely high values of IRF (>16%), MFI (>18) and MRV (>129 fl), makes the diagnosis of NMMA very unlikely. An underlying MDS should, therefore, be sought.

During a period of 2 years, from January 1996 to December 1997, 144 patients operated on for ruptured AAA in 10 hospitals were included in a multicenter retrospective study. Among the collected variables concerning each patient, those with potential relation to surgical mortality were studied: gender, age, diabetes, hypertension, cardiopathy, pulmonary obstructive disease, preoperative renal dysfunction, symptomatic cerebrovascular disease, peripheral vascular disease, hematocrit on admission, preoperative hypotension &amp;amp;amp;amp;amp;amp;amp;amp;lt; 80 mmHg, loss of consciousness, cardiac arrest, aortic aneurysm location (infrarenal versus non-infrarenal), iliac involvement, aneurysm size, type of rupture, left renal vein ligature, ligature of a patent inferior mesenteric artery, place of aortic cross-clamping, type of grafting, exclusion of both hypogastric arteries, venous technical complications, associated surgery, use of cell saver, intraoperative blood loss, and postoperative complications (renal failure, sepsis, coagulopathy, cardiac complications, pulmonary complications, colon ischemia, prosthetic graft complications, and need for reoperation). Those variables with statistical significance in the univariate analysis were introduced into a multivariate logistic regression model to determine the independent predictors of death. From our results we concluded that surgery for ruptured abdominal aortic aneurysms continues to have an excessively high mortality rate. Even though some preoperative variables could be identified as predictors of mortality, an absolute mortality risk has not yet been determined and the decision to negate surgery should be individualized rather than taken on that basis only. Early diagnosis and treatment of symptomatic aneurysms would improve mortality figures and selective screening should be contemplated.

The system is a component of the ICARUS project (http://www.fp7-icarus.eu) which has a goal to develop sensor, robotic and communication technologies for Human Search And Rescue teams. The support system for planning and managing complex SAR operations is implemented as a command and control component that integrates different sources of spatial information, such as maps of the affected area, satellite images and sensor data coming from the unmanned robots, in order to provide a situation snapshot to the rescue team who will make the necessary decisions. Support issues will include planning of frequency resources needed for given areas, prediction of coverage conditions, location of fixed communication relays, etc. The training system is developed for the ICARUS operators controlling UGVs (Unmanned Ground Vehicles), UAVs (Unmanned Aerial Vehicles) and USVs (Unmanned Surface Vehicles) from a unified Remote Control Station (RC2). The Training and Support system is implemented in SaaS model (Software as a Service). Therefore, its functionality is available over the Ethernet. SAR ICARUS teams from different countries can be trained simultaneously on a shared virtual stage. In this paper we will show the multi-robot 3D mapping component (aerial vehicle and ground vehicles). We will demonstrate that these 3D maps can be used for Training purpose. Finally we demonstrate current approach for ICARUS Urban SAR (USAR) and Marine SAR (MSAR) operation training.

The objective of this study was to determine the means by which each source of information about ODT influenced attitudes of children. Ten secondary schools from the south-east of Spain were stratified geographically. We performed a random selection of pupils from the first 4 years of compulsory secondary range, education (age 11-15 years). A validated self-administered questionnaire about attitudes toward ODT was completed anonymously. The adolescents had received information about ODT through several sources. The most frequent sources were television (86%), films (59%), and magazines (56%). Positive information from information sources was associated with more favorable attitudes toward ODT (P&amp;amp;lt;.05); those who received negative information had more unfavorable attitudes (P&amp;amp;lt;.05). Most information about ODT that reaches our children is through audiovisual means. Attitudes were more favorable among adolescents who have received positive information through the mass media, with more negative attitudes among those who received negative information.

To offset the organ shortage, living donation is being encouraged. Young persons form a sector of the population in whom early awareness is important to encourage favorable attitudes toward donation. Teachers play important roles in education and in generating attitudes. We analyzed the attitudes of secondary school teachers toward living organ donation and sought to determine the psychosocial variables that affect these attitudes. We randomly selected Teachers from 10 secondary schools in southeastern Spain. Their attitudes toward living donation were evaluated using a validated questionnaire, which was self-administered anonymously. The statistical tests were Student t test and the χ2 test. Regarding living kidney donation, 92% of teachers were in favor of related donation, decreasing to 16% when it was not from a related individual. In contrast, regarding related donations, 7% were not in favor, and 1% undecided. Teachers who had discussed the matter with their family and friends had more favorable attitudes (P&amp;amp;lt;.05). In the case of living liver donations, 91% were in favor of related donation (falling to 20% if not related), 7% were not in favor, and 2% had doubts. Attitudes were more favorable among women, teachers with children, and those who had discussed the matter with their family and friends (P&amp;amp;lt;.05). Teachers had favorable attitudes toward living related kidney or liver donation. Their students would receive positive information when they request relevant information.

The transplantation of pancreatic islets from animals as a treatment for diabetes mellitus could help with the current diabetes problem. Considerable advances have been made in recent years, with recent publications reporting improved conditions for carrying out clinical trials using porcine islets in humans with type 1 diabetes. Our objectives were (1) to analyze the acceptance of cell xenotransplantation for diabetes among Spanish adolescents and (2) to determine the psychosocial variables that might affect their attitudes and its relationship with other types of donation. Materials and methods. Random sampling was carried out among secondary school students in Spanish Schools. All subjects completed a validated questionnaire evaluating the acceptance of pancreatic islet xenotransplantation together with psychosocial aspects. Questionnaire completion was anonymous and self-administered. Student t test and the chi-square test were used for statistics. Results. The total number of respondents surveyed was 3633, and the mean age of the respondents was 11 Ϯ 18 years. Most of the respondents (62%; n ϭ 2195) would accept cells of animal origin if they suffered diabetes, 28% (n ϭ 1005) were unsure, and 10% (n ϭ 340) were against xenotransplantation. There is no connection with sex, age/year of study, or country. A high level of acceptance of animal cells was found among those who had a favorable attitude toward deceased organ donation and the xenotransplantation of solid organs and animal tissues (P Ͻ .001).

The role of the teacher is crucial in this respect. The objective of this study was to determine acceptance by secondary school teachers of an educational program about ODT. A random sample of secondary school teachers was taken from 10 secondary schools in the southeast of Spain. A total of 288 teachers were surveyed using a questionnaire that assessed the following; (1) acceptance of the educational program; (2) who should carry it out; and (3) some psychosocial variables related to ODT. Of the 288 secondary teachers surveyed, 283 of them responded to the acceptance of an educational program on ODT. Approximately half (54%) of the respondents believed that it would be appropriate to introduce an educational program about ODT in secondary schools, 22% believed that there were currently other more important educational considerations, 20% had doubts, and 4% believed that it would not be useful. The vast majority (71%) believed that a collaborator from the Regional Transplant Team would be the best person to carry out the program followed by any teacher (11%) or a teacher of ethics (9%). The remaining 9% were not sure. There was greater acceptance of an educational program about ODT among teachers who had a favorable attitude toward the matter (P = .003). An educational program about ODT in secondary education was not equally accepted by all teachers. Most teachers believed that the program should be delivered by the Transplant Coordination Center rather than teachers themselves.

A beneficial C2I system should assist the search and rescue process by enhancing first responder situational awareness, decision making and crisis handling by designing intuitive user interfaces that convey detailed and extensive information about the crisis and its evolution. The different components of C2I, their architectural and functional aspects are described along with the robot platform used for development and field testing.

We report such a case in a 32-week fetus presenting with polyhydramnios, growth restriction and multiple structural defects including alobar holoprosencephaly, facial abnormalities, clubfoot, clinodactyly and thumb agenesis. Fetal blood sampling revealed a 46,XY, del(13)(q22 → qter) abnormal male karyotype. Postmortem examination confirmed the prenatal findings and showed other manifestations of the syndrome. To our knowledge, this case represents the first in which the prenatal ultrasound detection of holoprosencephaly in association with distal limb abnormalities led to the prenatal diagnosis of the 13q-syndrome.
