The Recoil Proton Polarization: a new discriminative DVCS observable
Generalized parton distributions describe the correlations between the
longitudinal momentum and the transverse position of quarks and gluons in a
nucleon. They can be constrained by measuring photon leptoproduction
observables, arising from the interference between Bethe-Heitler and Deeply
virtual Compton scattering processes. At leading-twist/leading-order, the
amplitude of the latter is parameterized by complex integrals of the GPDs {H,
E, \~H, \~E} . As data collected on an unpolarized or longitudinally polarized
target constrains H and \~H, E is poorly known as it requires data collected
with a transversely polarized target, which is very challenging to implement in
fixed target experiments. The only alternative considered so far has been DVCS
on a neutron with a deuterium target, while assuming isospin symmetry and
absence of final-state interactions. Today, we introduce the polarization of
the recoil proton as a new DVCS observable, highly sensitive to E, which
appears feasible for an experimental study at a high-luminosity facility such
as Jefferson Lab

Two languages, two minds: flexible cognitive processing driven by language of operation.
People make sense of objects and events around them by classifying them into identifiable categories. The extent to which language affects this process has been the focus of a long-standing debate: Do different languages cause their speakers to behave differently? Here, we show that fluent German-English bilinguals categorize motion events according to the grammatical constraints of the language in which they operate. First, as predicted from cross-linguistic differences in motion encoding, bilingual participants functioning in a German testing context prefer to match events on the basis of motion completion to a greater extent than do bilingual participants in an English context. Second, when bilingual participants experience verbal interference in English, their categorization behavior is congruent with that predicted for German; when bilingual participants experience verbal interference in German, their categorization becomes congruent with that predicted for English. These findings show that language effects on cognition are context-bound and transient, revealing unprecedented levels of malleability in human cognition
Self-injury in youths who lost a parent to cancer: nationwide study of the impact of family-related and health-care-related factors.
BACKGROUND: Self-injury, a manifestation of severe psychological distress, is increased in cancer-bereaved youths. Little is known about the potential influence on the risk for self-injury of factors that could be clinically relevant to and modifiable by the health-care professionals involved in the care of the dying parent. METHODS: In a nationwide population-based anonymous study, 622 (73.1%) youths (aged 18-26) who, 6 to 9 years earlier at ages 13 to 16, had lost a parent to cancer answered study-specific questions about self-injury and factors related to the family and parental health care. RESULTS: Univariable analyses showed that the risk for self-injury was increased among cancer-bereaved youths who reported poor family cohesion the years before (relative risk [RR], 3.4, 95% confidence interval [CI], 2.5-4.6) and after the loss (RR, 3.3, 95% CI, 2.4-4.4), distrust in the health care provided to the dying parent (RR, 1.7, 95% CI, 1.2-2.4), perceiving poor health-care efforts to cure the parent (RR 1.5, 95% CI, 1.1-2.1) and poor efforts to prevent suffering (RR, 1.6, 95% CI, 1.1-2.4), that at least one of their parents had been depressed or had troubles in life (RR, 1.5, CI, 1.1-2.1) and believing 3 days before the loss that the treatment would probably cure the parent (RR, 1.6, CI, 1.1-2.3). In the total multivariable models, only poor family cohesion before and after the loss remained statistically significantly associated with self-injury. CONCLUSION: Poor family cohesion before and after the loss of a parent to cancer is associated with an increased risk of self-injury in teenage children

Teenagers want to be told when a parent's death is near: A nationwide study of cancer-bereaved youths' opinions and experiences.
BACKGROUND: We aimed to investigate cancer-bereaved youths' opinions and experiences of being told about a parent's imminent death from cancer and of barriers to this communication. MATERIAL AND METHODS: This nationwide population-based survey included 622/851 (73%) youths (aged 18-26) who at age 13-16, 6-9 years earlier had lost a parent to cancer. RESULTS: In total 595 of 610 (98%) of the participants stated that teenage children should be informed when the parent's death was imminent (i.e. a matter of hours or days, not weeks). 59% stated that they themselves had been told this, 37% by the parents, 7% by parents and healthcare professionals together and 8% by professionals only. Frequent reasons for why the teenager and parents did not talk about imminent death before loss were that one (n=106) or both (n=25) of the parents together with the teenage child had pretended that the illness was not that serious, or that none of the parents had been aware that death was imminent (n=80). Up to a couple of hours before the loss, 43% of participants had not realized that death was imminent. CONCLUSION: In this population-based study virtually all youth who at ages 13-16 had lost a parent to cancer afterwards stated that teenagers should be told when loss is near, i.e. a matter of hours or days, not weeks. Many stated that they had not been given this information and few were informed by professionals, with implications for future improvements in end-of-life care of patients with teenage children

Formation of the Scandinavian Obesity Surgery Registry, SOReg.
Obesity surgery is expanding, the quality of care is ever more important, and learning curve assessment should be established. A large registry cohort can show long-term effects on obesity and its comorbidities, complications, and long-term side effects of surgery, as well as changes in health-related quality of life (QoL). Sweden is ideally suited to the task of data collection and audit, with universal use of personal identification numbers, nation-wide registries permitting cross-matching to analyze causes of death, in-hospital care, and health-related absenteeism
