\u27A LABOUR OF LOVE\u27: A KING\u27S COLLEGE LONDON PSYCHIATRY SOCIETY EVENT TO CHALLENGE THE STIGMA ATTACHED TO MENTAL HEALTH PROBLEMS IN POST-NATAL WOMEN

Background: On the 9th October 2000, Dr Daksha Emson, a London based psychiatrist with bipolar affective disorder, tragically killed herself and her three-month-old baby daughter during a psychotic episode. An independent inquiry into Dr Emson’s death concluded that mental health stigma in the National Health Service was a factor that contributed to her death. Despite the morbidity and mortality attributed to the stigma attached to post-natal mental health problems there are very few programmes that have been developed to challenge it. King’s College London Undergraduate Psychiatry Society organized an event entitled, ‘A Labour of Love’: Perinatal Mental Health to address this issue. The event included a talk from an expert by experience, a mother who developed post-partum mental health problems. Design: We conducted a single-arm, pre-post comparison study on participants who attended the KCL Psych Soc event. Validated stigma scales on knowledge (Mental Health Knowledge Schedule (MAKS)), attitudes (Community Attitudes towards the Mentally Ill (CAMI)) and behaviour (Reported and Intended Behaviour Scale (RIBS)) were administered before and immediately after exposure to the event. Results: 27/27 (100%) of participants recruited responded. There was a statistically significant difference in the pre-MAKS score compared to the post-MAKS score (p=0.0003), the pre-RIBS score compared to the post-RIBS score (p=0.0068) and in the pre- CAMI score compared to the post-CAMI score (p=0.0042). Discussion: There were statistically significant reductions in stigma in the domains of knowledge, attitude and behavior following exposure to the KCL Psych Soc event and no adverse effects were reported. Our study revealed that a brief intervention made a highly significant impact and maybe useful in challenging the stigma around post-natal mental illness. However, more research in this area is required to determine if the changes are sustained before we can consider rolling out and scaling up such an initiative nationally and internationally

A KING’S COLLEGE LONDON UNDERGRADUATE PSYCHIATRY SOCIETY EVENT TO CHALLENGE THE STIGMA ATTACHED TO PSYCHOLOGICAL PROBLEMS IN HEALTHCARE PROFESSIONALS AND STUDENTS

Background: There are higher levels of psychological distress in healthcare professionals and students compared to the general population. Yet, despite the availability of effective treatment, many in this group continue to suffer in silence. Fear of exposure to stigmatization has been identified to be a major barrier to accessing and using mental health services. King’s College London Undergraduate Psychiatry Society (KCL PsychSoc) organized an event entitled, \u27What does bipolar disorder even mean? Psychological distress: How can we challenge the stigma?\u27. Healthcare professionals who themselves recovered from psychological problems and a mental health advocate with first-hand experience of psychological distress were invited to deliver talks followed by an interactive question and answer session. Design: We conducted a single-arm pre-post comparison study. People who attended the KCL Psych Soc event were recruited to participate. Validated stigma scales on knowledge (Mental Health Knowledge Schedule (MAKS), attitudes (Community Attitudes towards the Mentally Ill) and behavior (Reported and Intended Behavior Scale (RIBS)) were administered on participants before and immediately after exposure to the event. Results: 44/44 of the participants recruited completed the study (100% response rate). There were statistically significant changes in the respondents’ scores for all 3 stigma scales (p value MAKS <0.0001, p value CAMI<0.0001, p value RIBS=0.0011). Discussion: As far as the authors are aware, this is the first study to date of an anti-stigma intervention comprised of healthcare professionals with first-hand experience of psychological distress. The KCL PsychSoc event was associated with statistically significant changes in the respondents\u27 scores in all three of the stigma scales. More robust research in this area is needed before scaling up similar anti-stigma initiatives

Gray zones around diffuse large B cell lymphoma. Conclusions based on the workshop of the XIV meeting of the European Association for Hematopathology and the Society of Hematopathology in Bordeaux, France

The term “gray-zone” lymphoma has been used to denote a group of lymphomas with overlapping histological, biological, and clinical features between various types of lymphomas. It has been used in the context of Hodgkin lymphomas (HL) and non-Hodgkin lymphomas (NHL), including classical HL (CHL), and primary mediastinal large B cell lymphoma, cases with overlapping features between nodular lymphocyte predominant Hodgkin lymphoma and T-cell/histiocyte-rich large B cell lymphoma, CHL, and Epstein–Barr-virus-positive lymphoproliferative disorders, and peripheral T cell lymphomas simulating CHL. A second group of gray-zone lymphomas includes B cell NHL with intermediate features between diffuse large B cell lymphoma and classical Burkitt lymphoma. In order to review controversial issues in gray-zone lymphomas, a joint Workshop of the European Association for Hematopathology and the Society for Hematopathology was held in Bordeaux, France, in September 2008. The panel members reviewed and discussed 145 submitted cases and reached consensus diagnoses. This Workshop summary is focused on the most controversial aspects of gray-zone lymphomas and describes the panel’s proposals regarding diagnostic criteria, terminology, and new prognostic and diagnostic parameters

Multi-messenger observations of a binary neutron star merger

On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors. The Fermi Gamma-ray Burst Monitor independently detected a gamma-ray burst (GRB 170817A) with a time delay of ~1.7 s with respect to the merger time. From the gravitational-wave signal, the source was initially localized to a sky region of 31 deg2 at a luminosity distance of 40+8-8 Mpc and with component masses consistent with neutron stars. The component masses were later measured to be in the range 0.86 to 2.26 Mo. An extensive observing campaign was launched across the electromagnetic spectrum leading to the discovery of a bright optical transient (SSS17a, now with the IAU identification of AT 2017gfo) in NGC 4993 (at ~40 Mpc) less than 11 hours after the merger by the One- Meter, Two Hemisphere (1M2H) team using the 1 m Swope Telescope. The optical transient was independently detected by multiple teams within an hour. Subsequent observations targeted the object and its environment. Early ultraviolet observations revealed a blue transient that faded within 48 hours. Optical and infrared observations showed a redward evolution over ~10 days. Following early non-detections, X-ray and radio emission were discovered at the transient’s position ~9 and ~16 days, respectively, after the merger. Both the X-ray and radio emission likely arise from a physical process that is distinct from the one that generates the UV/optical/near-infrared emission. No ultra-high-energy gamma-rays and no neutrino candidates consistent with the source were found in follow-up searches. These observations support the hypothesis that GW170817 was produced by the merger of two neutron stars in NGC4993 followed by a short gamma-ray burst (GRB 170817A) and a kilonova/macronova powered by the radioactive decay of r-process nuclei synthesized in the ejecta

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals &lt;1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

Transient Musical Hallucinations in a Young Adult Male Associated with Alcohol Withdrawal

We present the case of a 25-year-old male who presented to A&E with isolated musical hallucinations, in the absence of audiological or neurological disease. The patient had a history of recreational drug use and a family history of psychosis. Hallucinations, which were preceded by discontinuation of alcohol and reinitiation of citalopram for depression, resolved spontaneously after three days. Aetiological factors are discussed alongside the existing literature. Whilst the underlying mechanisms underpinning musical hallucinations remain elusive, the case illustrates the potential role of alcohol withdrawal, serotonin toxicity, recreational drug use, and genetic vulnerability
