The soft X-ray monochromator at the SASE3 beamline of the European XFEL: from design to operation.

The SASE3 soft X-ray beamline at the European XFEL has been designed and built to provide experiments with a pink or monochromatic beam in the photon energy range 250-3000 eV. Here, the focus is monochromatic operation of the SASE3 beamline, and the design and performance of the SASE3 grating monochromator are reported. The unique capability of a free-electron laser source to produce short femtosecond pulses of a high degree of coherence challenges the monochromator design by demanding control of both photon energy and temporal resolution.

Parental Occupational Exposure is Associated With Their Children's Psychopathology: A Study of Families of Israeli First Responders.

Objective: To examine the association between parental occupational exposure to traumatic events and their children's mental health in families of First Responders (FRs), a neglected area of research.

Methods: In 208 families of Israeli FRs, children's symptoms and comorbidity patterns of seven psychiatric disorders were regressed on parental work-related variables, controlling for relevant covariates.

Results: Having a father working as a FR and higher paternal exposure were associated with a greater number of separation anxiety and posttraumatic stress symptoms, respectively.

Evidence-based medicine for all: what we can learn from a programme providing free access to an online clinical resource to health workers in resource-limited settings.

The rapidly changing landscape of medical knowledge and guidelines requires health professionals to have immediate access to current, reliable clinical resources. Access to evidence is instrumental in reducing diagnostic errors and generating better health outcomes. UpToDate, a leading evidence-based clinical resource is used extensively in the USA and other regions of the world and has been linked to lower mortality and length of stay in US hospitals.

Patient Retention in Therapeutic Communities for Substance Abuse Treatment: An Organizational-Environmental-Professional Perspective.

This study examined various organizational, environmental, and professional components of therapeutic communities in Israel and their relationship with patient retention rates. Key elements included the juxtaposition between objective and subjective components of social environments, as reflected in the perceptions of staff (mostly social workers) and patients. The current study's findings suggest that retention rates are predicted to be higher when staff receive more hours of supervision and identify less with their peers, and when their assessments of the organizational climate within facilities is closer to their patients' assessments of this aspect of organizational milieu.

Predictive factors of response and survival among chronic myelomonocytic leukemia patients treated with azacitidine.

Treatment of CMML remains a clinical challenge, with no drug demonstrating clear clinical benefit. Even if azacitidine is approved in the treatment of CMML, its role remains disputed. We report a cohort of 76 CMML patients (according to WHO classification) treated with azacitidine in 3 programs (French AZA compassionate program, Cleveland Clinic Foundation and H.
