Deep sea tests of a prototype of the KM3NeT digital optical module

The first prototype of a photo-detection unit of the future KM3NeT neutrino telescope has been deployed in the deepwaters of the Mediterranean Sea. This digital optical module has a novel design with a very large photocathode area segmented by the use of 31 three inch photomultiplier tubes. It has been integrated in the ANTARES detector for in-situ testing and validation. This paper reports on the first months of data taking and rate measurements. The analysis results highlight the capabilities of the new module design in terms of background suppression and signal recognition. The directionality of the optical module enables the recognition of multiple Cherenkov photons from the same (40)Kdecay and the localisation of bioluminescent activity in the neighbourhood. The single unit can cleanly identify atmospheric muons and provide sensitivity to the muon arrival directions

Alumni’s perceptions about commitment towards their university: drivers and consequences

This paper intends to capture alumni's assessments and perceptions about decisive dimensions of their commitment towards their alma mater. Their academic experience and current situation are highlighted. Moreover, their perception about the role of Higher Education Institution (HEI) in this commitment-relationship is likewise valuable to get their involvement. The study took place at a Portuguese university. Three focus groups, with 21 participants, were conducted to get consistent information permitting further developments. Data were analysed through NVivo software.The study gives insights revealing dimensions such as the relationships with teachers, extracurricular activities and initiation as decisive in their academic experience. Recommending and sharing their experience, underline evidence of what they are willing to give back. Moreover, their consciousness of bearing a mission to contribute to HEI's development was expressed through strong positive feelings, such as the sense of belonging, and pride at being part of the university, defined in their statements. But they all demand an effective ability of the university to communicate with them. Overall conclusions offer a scenario of alumni's commitment, giving HEI's management valuable clues to improvement, but its responsibility in this commitment-relationship was also stressed. Moreover, results also provide contributions to literature enabling other HEIs to replicate the study or simply use the results for their own development. Since the study occurred in a relatively weak alumni culture context, revealing the importance in promoting debate as a means to engage alumni in HEI's efforts for success, it presents insights for further developments in similar higher education environments.info:eu-repo/semantics/publishedVersio

Surgical site infection after gastrointestinal surgery in children : an international, multicentre, prospective cohort study

Introduction Surgical site infection (SSI) is one of the most common healthcare-associated infections (HAIs). However, there is a lack of data available about SSI in children worldwide, especially from low-income and middle-income countries. This study aimed to estimate the incidence of SSI in children and associations between SSI and morbidity across human development settings. Methods A multicentre, international, prospective, validated cohort study of children aged under 16 years undergoing clean-contaminated, contaminated or dirty gastrointestinal surgery. Any hospital in the world providing paediatric surgery was eligible to contribute data between January and July 2016. The primary outcome was the incidence of SSI by 30 days. Relationships between explanatory variables and SSI were examined using multilevel logistic regression. Countries were stratified into high development, middle development and low development groups using the United Nations Human Development Index (HDI). Results Of 1159 children across 181 hospitals in 51 countries, 523 (45 center dot 1%) children were from high HDI, 397 (34 center dot 2%) from middle HDI and 239 (20 center dot 6%) from low HDI countries. The 30-day SSI rate was 6.3% (33/523) in high HDI, 12 center dot 8% (51/397) in middle HDI and 24 center dot 7% (59/239) in low HDI countries. SSI was associated with higher incidence of 30-day mortality, intervention, organ-space infection and other HAIs, with the highest rates seen in low HDI countries. Median length of stay in patients who had an SSI was longer (7.0 days), compared with 3.0 days in patients who did not have an SSI. Use of laparoscopy was associated with significantly lower SSI rates, even after accounting for HDI. Conclusion The odds of SSI in children is nearly four times greater in low HDI compared with high HDI countries. Policies to reduce SSI should be prioritised as part of the wider global agenda.Peer reviewe

Global initiative for children’s surgery: a model of global collaboration to advance the surgical care of children

Background: Recommendations by the Lancet Commission on Global Surgery regarding surgical care in low- and middle-income countries (LMICs) require development to address the needs of children. The Global Initiative for Children’s Surgery (GICS) was founded in 2016 to identify solutions to problems in children’s surgery by utilizing the expertise of practitioners from around the world. This report details this unique process and underlying principles. Methods: Three global meetings convened providers of surgical services for children. Through working group meetings, participants reviewed the status of global children’s surgery to develop priorities and identify necessary resources for implementation. Working groups were formed under LMIC leadership to address specific priorities. By creating networking opportunities, GICS has promoted the development of LMIC-LMIC and HIC-LMIC partnerships. Results: GICS members identified priorities for children’s surgical care within four pillars: infrastructure, service delivery, training and research. Guidelines for provision of care at every healthcare level based on these pillars were created. Seventeen subspecialty, LMIC chaired working groups developed the Optimal Resources for Children’s Surgery (OReCS) document. The guidelines are stratified by subspecialty and level of health care: primary health center, first-, second- and third-level hospitals, and the national children’s hospital. The OReCS document delineates the personnel, equipment, facilities, procedures, training, research and quality improvement components at all levels of care. Conclusion: Worldwide collaboration with leadership by providers from LMICs holds the promise of improving children’s surgical care. GICS will continue to evolve in order to achieve the vision of safe, affordable, timely surgical care for all children.</p
