Public health emergency and psychological distress among healthcare workers: a scoping review.

BACKGROUND: Pandemics and natural disasters are immensely stressful events for frontline healthcare workers, as they provide patient care to a population undergoing the impacts of the disaster while experiencing such impacts to their personal lives themselves. With increased stressors to an already demanding job, frontline healthcare workers are at a higher risk of adverse effects to their mental health. The current COVID-19 pandemic has already shown to have had significant impact on the mental health of healthcare workers with increased rates of burnout, anxiety and depression. There is already literature showing the utility of individual programs at improving mental health, however, interventions at the organizational level are not well explored. This scoping review aims to provide an overview and determine the utility of a systematic review of the current body of literature assessing the effectiveness of mental health interventions at the organizational level for healthcare workers during or after a public health emergency. METHODS: Electronic databases such as Medline on OVID, CENTRAL, PsycINFO on OVID and Embase on OVID were searched. A targeted search of the grey literature was conducted to identify any non-indexed studies. The population, concept and context approach was used to develop the eligibility criteria. Articles were included if (1) they assessed the impact of interventions to improve wellbeing or reduce the distress on healthcare personnel, first responders or military actively providing medical care; (2) provided quantitative or qualitative data with clearly defined outcomes that focused on established mental health indicators or qualitative descriptions on distress and wellbeing, validated scales and workplace indicators; (3) focused on organizational level interventions that occurred in a public health crisis. RESULTS: The literature search resulted in 4007 citations and 115 potentially relevant full-text papers. All except 5 were excluded. There were four review articles and one experimental study. There were no other unpublished reports that warranted inclusion. CONCLUSIONS: There is a distinct lack of research examining organizational interventions addressing mental resilience and well-being in healthcare workers in disaster settings. A systematic review in this area would be low yield. There is a clear need for further research in this area.

Interventions to treat post-traumatic stress disorder (PTSD) in vulnerably housed populations and trauma-informed care: a scoping review.

OBJECTIVES: The goals of this study are to identify and analyse interventions that aim to treat post-traumatic stress disorder (PTSD) and complex PTSD in people who are vulnerably housed and to describe how these treatments have been delivered using trauma-informed care. DESIGN: Scoping review. SEARCH STRATEGY: We searched electronic databases including MEDLINE, Embase, PsycINFO, CINAHL, the Cochrane Library, Web of Science and PTSDpubs for published literature up to November 2021 for any studies that examined the treatment of PTSD in adults who were vulnerably housed. Websites of relevant organisations and other grey literature sources were searched to supplement the electronic database search. The characteristics and effect of the interventions were analysed. We also explored how the interventions were delivered and the elements of trauma-informed care that were described. RESULTS: 28 studies were included. We identified four types of interventions: (1) trauma focused psychotherapies; (2) non-trauma psychotherapies; (3) housing interventions and (4) pharmacotherapies. The trauma-informed interventions were small case series and the non-trauma focused therapies included four randomised controlled trials, were generally ineffective. Of the 10 studies which described trauma-informed care the most commonly named elements were physical and emotional safety, the experience of feeling heard and understood, and flexibility of choice. The literature also commented on the difficulty of providing care to this population including lack of private space to deliver therapy; the co-occurrence of substance use; and barriers to follow-up including limited length of stay in different shelters and high staff turnover. CONCLUSIONS: This scoping review identified a lack of high-quality trials to address PTSD in people who are vulnerably housed. There is a need to conduct well designed trials that take into account the unique setting of this population and which describe those elements of trauma-informed care that are most important and necessary.

Highly precise and developmentally programmed genome assembly in Paramecium requires ligase IV-dependent end joining.

During the sexual cycle of the ciliate Paramecium, assembly of the somatic genome includes the precise excision of tens of thousands of short, non-coding germline sequences (Internal Eliminated Sequences or IESs), each one flanked by two TA dinucleotides. It has been reported previously that these genome rearrangements are initiated by the introduction of developmentally programmed DNA double-strand breaks (DSBs), which depend on the domesticated transposase PiggyMac. These DSBs all exhibit a characteristic geometry, with 4-base 5' overhangs centered on the conserved TA, and may readily align and undergo ligation with minimal processing. However, the molecular steps and actors involved in the final and precise assembly of somatic genes have remained unknown. We demonstrate here that Ligase IV and Xrcc4p, core components of the non-homologous end-joining pathway (NHEJ), are required both for the repair of IES excision sites and for the circularization of excised IESs. The transcription of LIG4 and XRCC4 is induced early during the sexual cycle and a Lig4p-GFP fusion protein accumulates in the developing somatic nucleus by the time IES excision takes place. RNAi-mediated silencing of either gene results in the persistence of free broken DNA ends, apparently protected against extensive resection. At the nucleotide level, controlled removal of the 5'-terminal nucleotide occurs normally in LIG4-silenced cells, while nucleotide addition to the 3' ends of the breaks is blocked, together with the final joining step, indicative of a coupling between NHEJ polymerase and ligase activities. Taken together, our data indicate that IES excision is a "cut-and-close" mechanism, which involves the introduction of initiating double-strand cleavages at both ends of each IES, followed by DSB repair via highly precise end joining. This work broadens our current view on how the cellular NHEJ pathway has cooperated with domesticated transposases for the emergence of new mechanisms involved in genome dynamics.

Post-PharmD industry fellowship opportunities and proposed guidelines for uniformity.

The focus of this paper is to examine the surge in the development of post-PharmD industry fellowships (ie, pharmacy fellowship programs sponsored by the biopharmaceutical or pharmaceutical industry). These post-PharmD training programs do not fit the currently accepted definition of a pharmacy fellowship; therefore, the authors propose a new and distinct definition to encompass these fellowships. The authors provide program examples to showcase the establishment of the post-PharmD industry fellowship institutional centers. Finally, the authors provide recommendations to create uniformity in the programs of this relatively new category of post-PharmD training.
