Mobile videoconferencing for enhanced emergency medical communication - a shot in the dark or a walk in the park? ‐‐ A simulation study
Background: Videoconferencing on mobile phones may enhance communication, but knowledge on its quality in
various situations is needed before it can be used in medical emergencies. Mobile phones automatically activate
loudspeaker functionality during videoconferencing, making calls particularly vulnerable to background noise. The
aim of this study was to investigate if videoconferencing can be used between lay bystanders and Emergency
Medical Dispatch (EMD) operators for initial emergency calls during medical emergencies, under suboptimal sound
and light conditions.
Methods: Videoconferencing was tested between 90 volunteers and an emergency medical dispatcher in a
standardized scenario of a medical emergency. Three different environments were used for the trials: indoors with
moderate background noise, outdoors with daylight and much background noise, and outdoors during nighttime
with little background noise. Thirty participants were recruited for each of the three locations. After informed
consent, each participant was asked to use a video mobile phone to communicate with an EMD operator. During
the video call the EMD operator gave instructions for tasks to be performed by the participant. The video quality
from the caller to the EMD was evaluated by the EMD operator and rated on a five step scale ranging from “not
able to see” to “good video quality”. Sound quality between participants and EMD operators was assessed by a
method developed for this trial. Kruskal – Wallis and Chi-square tests were used for statistical analysis.
Results: Video quality was significantly different between the groups (p <0.001), and the nighttime group had
lower video quality. For most sessions in the nighttime group it was still possible to see actions done at the
simulated emergency site. All participants were able to perform their tasks according to the instructions given by
dispatchers, although with a need for more repetitions during sessions with much background noise. No calls were
rated by dispatchers as incomprehensible due to low sound quality and only 3% of the calls were considered
somewhat difficult or very difficult to understand.
Conclusions: Videoconferencing on mobile phones can be used for the initial emergency call during medical
emergencies also in suboptimal conditions
Videokonferanse og mobiltelefoner: Nye muligheter for 113
Denne oppgaven handler om kombinasjonen av telemedisin og akuttmedisin. Vi ønsket å undersøke om de siste års utvikling innen mobiltelefonteknologi har gitt muligheter som kan utnyttes av AMK.
Vi har gjennomført en eksperimentell studie, hvor vi gjennom 90 kasus har testet kvaliteten på videokonferanse mellom lekfolk og AMK-sentral. De 90 kasusene var fordelt på tre forskjellige lokalisasjoner som skulle representere ulike utfordringer med tanke på lysforhold og bakgrunnsstøy: Inne på et kjøpesenter med gode lysforhold og moderat bakgrunnsstøy, ute i dagslys ved en trafikkert gate med mye bakgrunnsstøy og ute om kvelden, i en mørk gate uten bakgrunnsstøy og med svært dårlige lysforhold.
Hovedfunnet i vår studie er at bildekvaliteten i den mørke gaten var dårligere enn på de to andre lokalisasjonene. Vi fant også en forskjell i forsøkdeltakernes oppfattelse av instruksjoner som ble gitt av AMK-operatøren, der gruppen med lite bakgrunnsstøy kom bedre ut enn de to andre gruppene.
Vi har ikke sammenlignet videokonferanse med tradisjonell telefoni, og kan derfor ikke dra noen konklusjoner for hvordan kommunikasjonen er med video i forhold til uten. Vi kan likevel konkludere med at videokonferanse kan gi god lydkvalitet både til og fra skadested, men at bildekvaliteten avhenger av lysforholdene

Challenges and opportunities for general practice specific CME in Europe - a narrative review of seven countries
Background: Several changes have led to general practitioners (GPs) working in a more differentiated setting today and being supported by other health professions. As practice changes, primary care specific continuing medical education (CME) may also need to adapt. By comparing different primary care specific CME approaches for GPs across Europe, we aim at identifying challenges and opportunities for future development.
Methods: Narrative review assessing, analysing and comparing CME programs for general practitioners across different north-western European countries (UK, Norway, the Netherlands, Belgium (Flanders), Germany, Switzerland, and France). Templates containing detailed items across seven dimensions of country-specific CME were developed and used. These dimensions are role of primary care within the health system, legal regulations regarding CME, published aims of CME, actual content of CME, operationalisation, funding and sponsorship, and evaluation.
Results: General practice specific CME in the countries under consideration are presented and comparatively analysed based on the dimensions defined in advance. This shows that each of the countries examined has different strengths and weaknesses. A clear pioneer cannot be identified. Nevertheless, numerous impulses for optimising future GP training systems can be derived from the examples presented.
Conclusions: Independent of country specific CME programs several fields of potential action were identified: the development of curriculum objectives for GPs, the promotion of innovative teaching and learning formats, the use of synergies in specialist GP training and CME, the creation of accessible yet comprehensive learning platforms, the establishment of clear rules for sponsorship, the development of new financing models, the promotion of fair competition between CME providers, and scientifically based evaluation.

Parent-of-origin-specific allelic associations among 106 genomic loci for age at menarche.
Age at menarche is a marker of timing of puberty in females. It varies widely between individuals, is a heritable trait and is associated with risks for obesity, type 2 diabetes, cardiovascular disease, breast cancer and all-cause mortality. Studies of rare human disorders of puberty and animal models point to a complex hypothalamic-pituitary-hormonal regulation, but the mechanisms that determine pubertal timing and underlie its links to disease risk remain unclear. Here, using genome-wide and custom-genotyping arrays in up to 182,416 women of European descent from 57 studies, we found robust evidence (P < 5 × 10(-8)) for 123 signals at 106 genomic loci associated with age at menarche. Many loci were associated with other pubertal traits in both sexes, and there was substantial overlap with genes implicated in body mass index and various diseases, including rare disorders of puberty. Menarche signals were enriched in imprinted regions, with three loci (DLK1-WDR25, MKRN3-MAGEL2 and KCNK9) demonstrating parent-of-origin-specific associations concordant with known parental expression patterns. Pathway analyses implicated nuclear hormone receptors, particularly retinoic acid and γ-aminobutyric acid-B2 receptor signalling, among novel mechanisms that regulate pubertal timing in humans. Our findings suggest a genetic architecture involving at least hundreds of common variants in the coordinated timing of the pubertal transition

Timing of singleton births by onset of labour and mode of birth in NHS maternity units in England, 2005-2014: A study of linked birth registration, birth notification, and hospital episode data
BACKGROUND: Maternity care has to be available 24 hours a day, seven days a week. It is known that obstetric intervention can influence the time of birth, but no previous analysis at a national level in England has yet investigated in detail the ways in which the day and time of birth varies by onset of labour and mode of giving birth.
METHOD: We linked data from birth registration, birth notification, and Maternity Hospital Episode Statistics and analysed 5,093,615 singleton births in NHS maternity units in England from 2005 to 2014. We used descriptive statistics and negative binomial regression models with harmonic terms to establish how patterns of timing of birth vary by onset of labour, mode of giving birth and gestational age.
RESULTS: The timing of birth by time of day and day of the week varies considerably by onset of labour and mode of birth. Spontaneous births after spontaneous onset are more likely to occur between midnight and 6am than at other times of day, and are also slightly more likely on weekdays than at weekends and on public holidays. Elective caesarean births are concentrated onto weekday mornings. Births after induced labours are more likely to occur at hours around midnight on Tuesdays to Saturdays and on days before a public holiday period, than on Sundays, Mondays and during or just after a public holiday.
CONCLUSION: The timing of births varies by onset of labour and mode of birth and these patterns have implications for midwifery and medical staffing. Further research is needed to understand the processes behind these findings

Cancers associated with Kaposi's sarcoma (KS) in AIDS: a link between KS herpesvirus and immunoblastic lymphoma
Kaposi's sarcoma (KS), common among persons with acquired immunodeficiency syndrome (AIDS), is caused by KS herpesvirus (KSHV) but whether KSHV causes other malignancies is uncertain. Using linked United States AIDS and cancer registries, we measured the incidence of specific malignancies in persons with AIDS (4–27 months after AIDS onset). We identified associations with KSHV by calculating a relative risk: cancer incidence in persons with KS (all were KSHV-infected) divided by incidence in persons without KS. Using Poisson regression, relative risks were adjusted for human immunodeficiency virus risk group, gender, age, race, and calendar year. We included 189 159 subjects (26 972 with KS). Immunoblastic lymphoma was significantly associated with KS (506 cases; relative risks: unadjusted 2.44, 95%CI 2.00–2.96, adjusted 1.58, 95%CI 1.29–1.93). Only one immunoblastic lymphoma had pleura as primary site. None of 37 other specified malignancies (other non-Hodgkin lymphomas, haematological malignancies, solid tumours) was significantly associated with KS. In summary, the association of immunoblastic lymphoma with KS was specific among examined malignancies and remained significant after statistical adjustment. Our findings, and the previously demonstrated presence of KSHV in the histologically related primary effusion lymphoma, suggest that KSHV is involved in the pathogenesis of some immunoblastic lymphomas. © 2001 Cancer Research Campaig
