Abstract
Exposure to childhood trauma has been associated with psychotic symptoms, being at ultra-high risk for psychosis (UHR), and psychotic disorders such as schizophrenia. Negative self-beliefs have been shown to partially mediate the relationship between childhood trauma and paranoia and have been shown to be characteristic of patients with psychosis. However, whether the association between childhood trauma and being at high risk of developing psychosis (e.g., UHR) and paranoia symptoms is mediated by altered cognitive schema is unknown and warrants investigation to inform preventive interventions. Data was collected on 30 UHR patients from Outreach and Support in South London about exposure to childhood trauma, cognitive schema, paranoia and cannabis use. Relative to healthy controls (n = 38), UHR patients were significantly more likely to report exposure to various types of childhood trauma (emotional and sexual abuse, and emotional and physical neglect), had more negative schema and less positive schema about themselves and others, and were more likely to use cannabis more than once a month. Emotional neglect was found to be significantly associated with UHR status even after controlling for the effects of previous exposure to cannabis use (b = 0.262, 95% CI: 0.115-0.408), and this association was partially mediated by negative self-schema (b = 0.045, 95% CI: 0.004-0.159). Similarly, emotional neglect was significantly associated with paranoia (b = 1.354, 95% CI: 0.246-2.462), and this association was partially mediated by negative self-schema (b = 0.988, 95% CI: 0.323-1.895). These findings provide preliminary evidence about the cognitive mechanisms that may underlie the association between childhood trauma and later risk for psychosis.

Abstract
Space radiation is a great danger to electronics and astronauts onboard space vessels. The spectral flux of space electrons, protons and ions for example in the radiation belts is inherently broadband, but this is a feature hard to mimic with conventional radiation sources. Using laser-plasma-accelerators, we reproduced relativistic, broadband radiation belt flux in the laboratory, and used this man-made space radiation to test the radiation hardness of space electronics. Such close mimicking of space radiation in the lab builds on the inherent ability of laser-plasma-accelerators to directly produce broadband Maxwellian-type particle flux, akin to conditions in space. In combination with the established sources, utilisation of the growing number of ever more potent laser-plasma-accelerator facilities worldwide as complementary space radiation sources can help alleviate the shortage of available beamtime and may allow for development of advanced test procedures, paving the way towards higher reliability of space missions.

Abstract
OBJECTIVES To investigate the efficacy and safety of CS1002, an over-the-counter cough treatment containing diphenhydramine, ammonium chloride and levomenthol in a cocoa-based demulcent. DESIGN A multicentre, randomised, parallel group, controlled, single-blinded study in participants with acute upper respiratory tract infection-associated cough. SETTING 4 general practitioner (GP) surgeries and 14 pharmacies in the UK. PARTICIPANTS Participants aged ≥18 years who self-referred to a GP or pharmacist with acute cough of <7 days' duration. Participant inclusion criterion was cough severity ≥60 mm on a 0-100 mm visual analogue scale (VAS). Exclusion criteria included current smokers or history of smoking within the past 12 months (including e-cigarettes). 163 participants were randomised to the study (mean participant age 38 years, 57% females). INTERVENTIONS Participants were randomised to CS1002 (Unicough) or simple linctus (SL), a widely used cough treatment, and treatment duration was 7 days or until resolution of cough. MAIN OUTCOME MEASURES The primary analysis was intention-to-treat (157 participants) and comprised cough severity assessed using a VAS after 3 days' treatment (prespecified primary end point at day 4). Cough frequency, sleep disruption, health status (Leicester Cough Questionnaire (LCQ-acute)) and cough resolution were also assessed. RESULTS At day 4 (primary end point), the adjusted mean difference (95% CI) in cough severity VAS between CS1002 and SL was -5.9 mm (-14.4 to 2.7), p=0.18. At the end of the study (day 7) the mean difference in cough severity VAS was -4.2 mm (-12.2 to 3.9), p=0.31. CS1002 was associated with a greater reduction in cough sleep disruption (mean difference -11.6 mm (-20.6 to 2.7), p=0.01) and cough frequency (mean difference -8.1 mm (-16.2 to 0.1), p=0.05) compared with SL. There was greater improvement in LCQ-acute quality of life scores with CS1002 compared with SL: mean difference (95% CI) 1.2 (0.05 to 2.36), p=0.04 after 5 days' treatment. More participants prematurely stopped treatment due to cough improvement in the CS1002 group (24.4%) compared with SL (10.7%; p=0.02). Adverse events (AEs) were comparable between CS1002 (20.5%) and SL (27.6%) and largely related to the study indication. 6 participants (7%) in the CS1002 group reduced the dose of medication due to drowsiness/tiredness, which subsequently resolved. These events were not reported by participants as AEs. CONCLUSIONS Although the primary end point was not achieved, CS1002 was associated with greater reductions in cough frequency, sleep disruption and improved health status compared with SL. TRIAL REGISTRATION NUMBER EudraCT number 2014-004255-31.

Abstract
BACKGROUND Avoralstat is a potent small-molecule oral plasma kallikrein inhibitor under development for treatment of hereditary angioedema (HAE). This first-in-human study evaluated the safety, tolerability, pharmacokinetics, and pharmacodynamics of avoralstat. METHODS This double-blind, placebo-controlled, ascending-dose cohort trial evaluated avoralstat single doses of 50, 125, 250, 500, and 1000 mg and multiple doses up to 2400 mg daily (100, 200, 400, and 800 mg every 8 h [q8 h] up to 7 days). RESULTS Avoralstat (n = 71) was generally well tolerated with no signals for a safety concern; there were no serious adverse events (AEs) or discontinuations due to AEs, and compared to placebo (n = 18), no notable difference in AEs. Four moderate severity AEs were reported in two subjects; syncope after a single 250 mg dose (one subject) and abdominal pain, back pain, and eczema after multiple doses of 800 mg avoralstat (one subject). For multiple-dose cohorts, the incidence of gastrointestinal AEs was highest at the 2400 mg/day dose. Elimination of avoralstat was bi-exponential with a terminal half-life of 12-31 h. Inhibition of plasma kallikrein was observed at all doses, and the degree of inhibition was highly correlated with avoralstat concentrations (R = 0.93). Mean avoralstat concentrations at doses ≥400 mg q8 h met or exceeded plasma kallikrein EC50 values throughout the dosing interval. CONCLUSION Avoralstat was well tolerated, and drug exposure was sufficient to meet target levels for inhibition of plasma kallikrein. Based on these results, the 400 mg q8 h dose was selected for further evaluation in patients with HAE.

Abstract
Pseudohyperkalaemia is an uncommon and frequently unrecognised biochemical abnormality. It occurs as a consequence of aggregation and lysis of platelets in vitro. As a result, potassium is released, which causes an elevated serum concentration. We present the case of a 21-year-old man with a traumatic splenic injury necessitating laparotomy and splenectomy. Following surgery he developed hyperkalaemia. Further investigations diagnosed pseudohyperkalaemia, one of the causes of which is thrombocytosis secondary to splenectomy.

Abstract
Carcinogenic response is compared to noncarcinogenic toxicity in that group of chemicals tested by the National Cancer Institute (NCI) and National Toxicology Program (NTP) between 1976 and 1982 and reported in the Carcinogenesis Technical Report Series. A positive finding of carcinogenicity in the bioassay is correlated with the degree of noncarcinogenic chronic toxicity of the dose applied. Comparisons of acute toxicity (LD50) with carcinogenic potency show that they are correlated, but the correlation may in part be an artifact, since doses used in the NCI/NTP carcinogenesis bioassays are toxic and because reliable measures of potency can only be derived for positive carcinogenic responses. The high correlations for certain classes of chemicals and the relationship of chronic toxicity to positive carcinogenic finding suggest that these relationships are more than spurious. Since toxicities in different species are highly correlated, these findings imply that carcinogenicities in different species are also correlated.

Abstract
The NHS Care Records Service will connect more than 30,000 GPs and 270 acute, community and mental health NHS trusts in a single, secure national system. This will support electronic transmission of prescriptions (ETP) to pharmacies linked to the NHS Care Records Service spine and also to the national Prescription Pricing Authority (PPA). This article reflects on the experience of evaluating three pilot implementations of ETP in England in 2002, and concludes that some evaluation findings may be relevant not only to ETP messaging but also to electronic health record (EHR) systems and hence to the broader implications of implementing the NHS Care Records Service.

Abstract
The concept of the informed health-care ‘consumer’ rests on the availability of comprehensible information. While various bodies have made information available, its quality is mixed. Information is sometimes untrustworthy, incomprehensible, or simply forgotten by patients. An understandable record of advice is more likely to bring about compliance with treatment and lessen the need to revisit the surgery. This is a report of the revision of health-care information leaflets and their testing on 59 volunteers (61-81 years old). Presentation, reading ease and understanding were considered. The goal of making health-care information comprehensible was achieved. Guidelines for revising such material are described and illustrated. The informed consumer goal may be achievable if writers of health-care information attend to communication as much as to the adequacy of their medical advice.

Abstract
We used telemedicine to improve genetics services to patients in the rural northwestern region of Florida. Patients were first seen via videoconference by a genetic counsellor, who obtained family and medical history. A local paediatrician then performed the physical examination, and a plan for evaluation was established. The videoconferencing equipment was connected at a bandwidth of 384 kbit/s, using three ISDN lines. During the first three telemedicine clinics, seven patients were evaluated and then returned to the centre for a face-to-face consultation with the clinical geneticist. No new diagnoses were made face-to-face that had not been identified by telemedicine. No diagnoses made by telemedicine were judged to be wrong when the child was evaluated face-to-face. During a two-year study of patient satisfaction with 12 telegenetics clinics, the 50 families evaluated via videoconferencing were asked to complete surveys; 40 surveys were returned (a response rate of 80%). All individuals either strongly agreed or agreed that the evaluation of their child was appropriate, sufficient and sufficiently protective of their child's privacy. The waiting time for a new patient consultation with the clinical genetics team was 16.9 months (SD 1.9) at the start and 3.0 months (SD 1.0) at the end of the trial period. The difference was significant ( t-test, P<0.0001). Telegenetics allows more rapid assurance that a genetic syndrome has not been identified, or a quicker initial evaluation and diagnosis for children who do have an identifiable genetic syndrome.
