Study of the lineshape of the chi(c1) (3872) state

A study of the lineshape of the chi(c1) (3872) state is made using a data sample corresponding to an integrated luminosity of 3 fb(-1) collected in pp collisions at center-of-mass energies of 7 and 8 TeV with the LHCb detector. Candidate chi(c1)(3872) and psi(2S) mesons from b-hadron decays are selected in the J/psi pi(+)pi(-) decay mode. Describing the lineshape with a Breit-Wigner function, the mass splitting between the chi(c1 )(3872) and psi(2S) states, Delta m, and the width of the chi(c1 )(3872) state, Gamma(Bw), are determined to be (Delta m=185.598 +/- 0.067 +/- 0.068 Mev,)(Gamma BW=1.39 +/- 0.24 +/- 0.10 Mev,) where the first uncertainty is statistical and the second systematic. Using a Flatte-inspired model, the mode and full width at half maximum of the lineshape are determined to be (mode=3871.69+0.00+0.05 MeV.)(FWHM=0.22-0.04+0.13+0.07+0.11-0.06-0.13 MeV, ) An investigation of the analytic structure of the Flatte amplitude reveals a pole structure, which is compatible with a quasibound D-0(D) over bar*(0) state but a quasivirtual state is still allowed at the level of 2 standard deviations

Measurement of the CKM angle γγ in B±→DK±B^\pm\to D K^\pm and B±→Dπ±B^\pm \to D π^\pm decays with D→KS0h+h−D \to K_\mathrm S^0 h^+ h^-

A measurement of $CP$-violating observables is performed using the decays $B^\pm\to D K^\pm$ and $B^\pm\to D \pi^\pm$, where the $D$ meson is reconstructed in one of the self-conjugate three-body final states $K_{\mathrm S}\pi^+\pi^-$ and $K_{\mathrm S}K^+K^-$ (commonly denoted $K_{\mathrm S} h^+h^-$). The decays are analysed in bins of the $D$-decay phase space, leading to a measurement that is independent of the modelling of the $D$-decay amplitude. The observables are interpreted in terms of the CKM angle $\gamma$. Using a data sample corresponding to an integrated luminosity of $9\,\text{fb}^{-1}$ collected in proton-proton collisions at centre-of-mass energies of $7$, $8$, and $13\,\text{TeV}$ with the LHCb experiment, $\gamma$ is measured to be $\left(68.7^{+5.2}_{-5.1}\right)^\circ$. The hadronic parameters $r_B^{DK}$, $r_B^{D\pi}$, $\delta_B^{DK}$, and $\delta_B^{D\pi}$, which are the ratios and strong-phase differences of the suppressed and favoured $B^\pm$ decays, are also reported

Hoe ziekenhuizen patiënten en/of naasten betrekken na een calamiteit.

In dit onderzoek zijn we op zoek gegaan naar het antwoord op de vraag wat men in de ziekenhuissector ziet als de gewenste manier van omgaan met patiënten en/of naasten na een calamiteit. Om dit antwoord te vinden hebben we gebruik gemaakt van verschillende deelonderzoeken: – interviews met patiënten en/of naasten die betrokken waren bij een calamiteit – focusgroepen met vertegenwoordigers van ziekenhuizen – focusgroepen met vertegenwoordigers van cliëntenraden en – interviews met de Patiëntenfederatie en de Nederlandse Vereniging van Ziekenhuizen (NVZ) De belangrijkste bevinding van dit onderzoek is dat vrijwel iedereen het belangrijk vindt om patiënten en/of naasten actief bij het calamiteitenonderzoek te betrekken. Dat begint al bij de vraag of en hoe patiënten en/of naasten bij het calamiteitenonderzoek betrokken willen worden

Medical Dispute Committees in the Netherlands: a qualitative study of patient expectations and experiences.

Background Health care incidents, such as medical errors, cause tragedies all over the world. Recent legislation in the Netherlands has established medical dispute committees to provide for an appeals procedure offering an alternative to civil litigation and to meet the needs of clients. Dispute committees incorporate a hybrid procedure where one can file a complaint and a claim for damages resulting in a verdict without going to court. The procedure is at the crossroads of complaints law and civil litigation. This study seeks to analyze to what extent patients and family members' expectations and experiences with dispute committees match the goals of the new legislation. Methods This qualitative, retrospective research includes in-depth, semi-structured, face-to-face interviews with patients or family members who filed a complaint with a dispute committee in the Netherlands. The researchers conducted an inductive, thematic analysis of the qualitative data. Results A total of 26 interviews were held with 30 patients and family members. The results showed that participants particularly felt the need to be heard and to make a positive impact on health care. Some wished to be financially compensated, for others money was the last thing on their mind. The results demonstrated the existence of unequal power relationships between participants and both the defendant and dispute committee members. Participants reported the added value of (legal) support and expressed the need for dialogue at the hearing. Participants sometimes experienced closure after the proceedings, but often did not feel heard or felt a lack of a practical outcome and a tangible improvement. Conclusions This study shows that participants' expectations and experiences were not always met by the current set up of the dispute committee proceedings. Participants did not feel heard, while they did value the potential for monetary compensation. In addition, some participants did not experience an empowered position but rather a feeling of a power misbalance. The feeling of a power misbalance and not being heard might be explained by existing epistemic injustice, which is a concept that should be carefully considered in processes after health care incidents

Patients at the centre after a health care incident: a scoping review of hospital strategies targeting communication and nonmaterial restoration.

Objective This study aimed to provide an overview of the strategies adopted by hospitals that target effective communication and nonmaterial restoration (i.e., without a financial or material focus) after health care incidents, and to formulate elements in hospital strategies that patients consider essential by analysing how patients have evaluated these strategies. Background In the aftermath of a health care incident, hospitals are tasked with responding to the patients' material and nonmaterial needs, mainly restoration and communication. Currently, an overview of these strategies is lacking. In particular, a gap exists concerning how patients evaluate these strategies. Search Strategy and Inclusion Criteria To identify studies in this scoping review, and following the methodological framework set out by Arksey and O'Malley, seven subject‐relevant electronic databases were used (PubMed, Medline, Embase, CINAHL, PsycARTICLES, PsycINFO and Psychology & Behavioral Sciences Collection). Reference lists of included studies were also checked for relevant studies. Studies were included if published in English, after 2000 and as peer‐reviewed articles. Main Results and Synthesis The search yielded 13,989 hits. The review has a final inclusion of 16 studies. The inclusion led to an analysis of five different hospital strategies: open disclosure processes, communication‐and‐resolution programmes, complaints procedures, patients‐as‐partners in learning from health care incidents and subsequent disclosure, and mediation. The analysis showed three main domains that patients considered essential: interpersonal communication, organization around disclosure and support and desired outcomes
