Prediction of non-recovery from ventilator-demanding acute respiratory failure, ARDS and death using lung damage biomarkers: data from a 1200-patient critical care randomized trial

Abstract Background It is unclear whether biomarkers of alveolar damage (surfactant protein D, SPD) or conductive airway damage (club cell secretory protein 16, CC16) measured early after intensive care admittance are associated with one-month clinical respiratory prognosis. If patients who do not recover respiratory function within one month can be identified early, future experimental lung interventions can be aimed toward this high-risk group. We aimed to determine, in a heterogenous critically ill population, whether baseline profound alveolar damage or conductive airway damage has clinical respiratory impact one month after intensive care admittance. Methods Biobank study of biomarkers of alveolar and conductive airway damage in intensive care patients was conducted. This was a sub-study of 758 intubated patients from a 1200-patient randomized trial. We split the cohort into a “learning cohort” and “validating cohort” based on geographical criteria: northern sites (learning) and southern sites (validating). Results Baseline SPD above the 85th percentile in the “learning cohort” predicted low chance of successful weaning from ventilator within 28 days (adjusted hazard ratio 0.6 [95% CI 0.4–0.9], p = 0.005); this was confirmed in the validating cohort. CC16 did not predict the endpoint. The absolute risk of not being successfully weaned within the first month was 48/106 (45.3%) vs. 175/652 (26.8%), p < 0.0001 (high SPD vs. low SPD). The chance of being “alive and without ventilator ≥20 days within the first month” was lower among patients with high SPD (adjusted OR 0.2 [95% CI 0.2–0.4], p < 0.0001), confirmed in the validating cohort, and the risk of ARDS was higher among patients with high SPD (adjusted OR 3.4 [95% CI 1.0–11.4], p = 0.04)—also confirmed in the validating cohort. Conclusion Early profound alveolar damage in intubated patients can be identified by SPD blood measurement at intensive care admission, and high SPD level is a strong independent predictor that the patient suffers from ARDS and will not recover independent respiratory function within one month. This knowledge can be used to improve diagnostic and prognostic models and to identify the patients who most likely will benefit from experimental interventions aiming to preserve alveolar tissue and therefore respiratory function. Trial registration This is a sub-study to the Procalcitonin And Survival Study (PASS), Clinicaltrials.gov ID: NCT00271752, first registered January 1, 200

Statement on virginity testing

Virginity testing (virginity examination) is a gynecological examination that is intended to correlate the status and appearance of the hymen with previous sexual contact to determine whether a female has had or is habituated to sexual intercourse. Virginity examinations are practiced in many countries, often forcibly, including in detention places; on women who allege rape or are accused of prostitution; and as part of public or social policies to control sexuality. The Independent Forensic Expert Group (IFEG) - thirty-five preeminent independent forensic experts from eighteen countries specialized in evaluating and documenting the physical and psychological effects of torture and ill-treatment - released a statement on the practice in December 2014

Statement of the Independent Forensic Expert Group on Conversion Therapy

Conversion therapy is a set of practices that aim to change or alter an individual’s sexual orientation or gender identity. It is premised on a belief that an individual’s sexual orientation or gender identity can be changed and that doing so is a desirable outcome for the individual, family, or community. Other terms used to describe this practice include sexual orientation change effort (SOCE), reparative therapy, reintegrative therapy, reorientation therapy, ex-gay therapy, and gay cure. Conversion therapy is practiced in every region of the world. We have identified sources confirming or indicating that conversion therapy is performed in over 60 countries.1 In those countries where it is performed, a wide and variable range of practices are believed to create change in an individual’s sexual orientation or gender identity. Some examples of these include: talk therapy or psychotherapy (e.g., exploring life events to identify the cause); group therapy; medication (including anti-psychotics, anti- depressants, anti-anxiety, and psychoactive drugs, and hormone injections); Eye Movement Desensitization and Reprocessing (where an individual focuses on a traumatic memory while simultaneously experiencing bilateral stimulation); electroshock or electroconvulsive therapy (ECT) (where electrodes are attached to the head and electric current is passed between them to induce seizure); aversive treatments (including electric shock to the hands and/or genitals or nausea-inducing medication administered with presentation of homoerotic stimuli); exorcism or ritual cleansing (e.g., beating the individual with a broomstick while reading holy verses or burning the individual’s head, back, and palms); force-feeding or food deprivation; forced nudity; behavioural conditioning (e.g., being forced to dress or walk in a particular way); isolation (sometimes for long periods of time, which may include solitary confinement or being kept from interacting with the outside world); verbal abuse; humiliation; hypnosis; hospital confinement; beatings; and “corrective” rape. Conversion therapy appears to be performed widely by health professionals, including medical doctors, psychiatrists, psychologists, sexologists, and therapists. It is also conducted by spiritual leaders, religious practitioners, traditional healers, and community or family members. Conversion therapy is undertaken both in contexts under state control, e.g., hospitals, schools, and juvenile detention facilities, as well as in private settings like homes, religious institutions, or youth camps and retreats. In some countries, conversion therapy is imposed by the order or instructions of public officials, judges, or the police. The practice is undertaken with both adults and minors who may be lesbian, gay, bisexual, trans, or gender diverse. Parents are also known to send their children back to their country of origin to receive it. The practice supports the belief that non-heterosexual orientations are deviations from the norm, reflecting a disease, disorder, or sin. The practitioner conveys the message that heterosexuality is the normal and healthy sexual orientation and gender identity. The purpose of this medico-legal statement is to provide legal experts, adjudicators, health care professionals, and policy makers, among others, with an understanding of: 1) the lack of medical and scientific validity of conversion therapy; 2) the likely physical and psychological consequences of undergoing conversion therapy; and 3) whether, based on these effects, conversion therapy constitutes cruel, inhuman, or degrading treatment or torture when individuals are subjected to it forcibly2 or without their consent. This medico-legal statement also addresses the responsibility of states in regulating this practice, the ethical implications of offering or performing it, and the role that health professionals and medical and mental health organisations should play with regards to this practice. Definitions of conversion therapy vary. Some include any attempt to change, suppress, or divert an individual’s sexual orientation, gender identity, or gender expression. This medico-legal statement only addresses those practices that practitioners believe can effect a genuine change in an individual’s sexual orientation or gender identity. Acts of physical and psychological violence or discrimination that aim solely to inflict pain and suffering or punish individuals due to their sexual orientation or gender identity, are not addressed, but are wholly condemned. This medico-legal statement follows along the lines of our previous publications on Anal Examinations in Cases of Alleged Homosexuality1 and on Forced Virginity Testing.2 In those statements, we opposed attempts to minimise the severity of physical and psychological pain and suffering caused by these examinations by qualifying them as medical in nature. There is no medical justification for inflicting on individuals torture or other cruel, inhuman, or degrading treatment or punishment. In addition, these statements reaffirmed that health professionals should take no role in attempting to control sexuality and knowingly or unknowingly supporting state-sponsored policing and punishing of individuals based on their sexual orientation or gender identity

Picking Up the PiecesHarmonising and Collating Seabed Substrate Data for European Maritime Areas

The poor access to data on the marine environment is a handicap to government decision-making, a barrier to scientific understanding and an obstacle to economic growth. In this light, the European Commission initiated the European Marine Observation and Data Network (EMODnet) in 2009 to assemble and disseminate hitherto dispersed marine data. In the ten years since then, EMODnet has become a key producer of publicly available, harmonised datasets covering broad areas. This paper describes the methodologies applied in EMODnet Geology project to produce fully populated GIS layers of seabed substrate distribution for the European marine areas. We describe steps involved in translating national seabed substrate data, conforming to various standards, into a uniform EMODnet substrate classification scheme (i.e., the Folk sediment classification). Rock and boulders form an additional substrate class. Seabed substrate data products at scales of 1:250,000 and 1:1 million, compiled using descriptions and analyses of seabed samples as well as interpreted acoustic images, cover about 20% and 65% of the European maritime areas, respectively. A simple confidence assessment, based on sample and acoustic coverage, is helpful in identifying data gaps. The harmonised seabed substrate maps are particularly useful in supraregional, transnational and pan-European marine spatial planning
