Abstract
INTRODUCTION The multiorgan impact of moderate to severe coronavirus infections in the post-acute phase is still poorly understood. We aimed to evaluate the excess burden of multiorgan abnormalities after hospitalisation with COVID-19, evaluate their determinants, and explore associations with patient-related outcome measures. METHODS In a prospective, UK-wide, multicentre MRI follow-up study (C-MORE), adults (aged ≥18 years) discharged from hospital following COVID-19 who were included in Tier 2 of the Post-hospitalisation COVID-19 study (PHOSP-COVID) and contemporary controls with no evidence of previous COVID-19 (SARS-CoV-2 nucleocapsid antibody negative) underwent multiorgan MRI (lungs, heart, brain, liver, and kidneys) with quantitative and qualitative assessment of images and clinical adjudication when relevant. Individuals with end-stage renal failure or contraindications to MRI were excluded. Participants also underwent detailed recording of symptoms, and physiological and biochemical tests. The primary outcome was the excess burden of multiorgan abnormalities (two or more organs) relative to controls, with further adjustments for potential confounders. The C-MORE study is ongoing and is registered with ClinicalTrials.gov, NCT04510025. FINDINGS Of 2710 participants in Tier 2 of PHOSP-COVID, 531 were recruited across 13 UK-wide C-MORE sites. After exclusions, 259 C-MORE patients (mean age 57 years [SD 12]; 158 [61%] male and 101 [39%] female) who were discharged from hospital with PCR-confirmed or clinically diagnosed COVID-19 between March 1, 2020, and Nov 1, 2021, and 52 non-COVID-19 controls from the community (mean age 49 years [SD 14]; 30 [58%] male and 22 [42%] female) were included in the analysis. Patients were assessed at a median of 5·0 months (IQR 4·2-6·3) after hospital discharge. Compared with non-COVID-19 controls, patients were older, living with more obesity, and had more comorbidities. Multiorgan abnormalities on MRI were more frequent in patients than in controls (157 [61%] of 259 vs 14 [27%] of 52; p<0·0001) and independently associated with COVID-19 status (odds ratio [OR] 2·9 [95% CI 1·5-5·8]; padjusted=0·0023) after adjusting for relevant confounders. Compared with controls, patients were more likely to have MRI evidence of lung abnormalities (p=0·0001; parenchymal abnormalities), brain abnormalities (p<0·0001; more white matter hyperintensities and regional brain volume reduction), and kidney abnormalities (p=0·014; lower medullary T1 and loss of corticomedullary differentiation), whereas cardiac and liver MRI abnormalities were similar between patients and controls. Patients with multiorgan abnormalities were older (difference in mean age 7 years [95% CI 4-10]; mean age of 59·8 years [SD 11·7] with multiorgan abnormalities vs mean age of 52·8 years [11·9] without multiorgan abnormalities; p<0·0001), more likely to have three or more comorbidities (OR 2·47 [1·32-4·82]; padjusted=0·0059), and more likely to have a more severe acute infection (acute CRP >5mg/L, OR 3·55 [1·23-11·88]; padjusted=0·025) than those without multiorgan abnormalities. Presence of lung MRI abnormalities was associated with a two-fold higher risk of chest tightness, and multiorgan MRI abnormalities were associated with severe and very severe persistent physical and mental health impairment (PHOSP-COVID symptom clusters) after hospitalisation. INTERPRETATION After hospitalisation for COVID-19, people are at risk of multiorgan abnormalities in the medium term. Our findings emphasise the need for proactive multidisciplinary care pathways, with the potential for imaging to guide surveillance frequency and therapeutic stratification.

Abstract
The purpose of this study was to determine the influence of sedentary behavior (SB) on the frequency of health complaints (fHC) as well as on self-rated health (SRH) and body mass index (BMI), and to determine whether physical activity (PA) moderated this influence. Data were obtained from the Youth Survey Luxembourg 2019 (N = 2,802), a nationally representative stratified random sample of all youths aged 16 to 29 years who were living in Luxembourg. fHC is a composite measure of eight common psychosomatic health complaints, SRH was measured on a five-point scale, and BMI was calculated by dividing participants' body weight by the square of their body height (kg/m2). PA and SB values were obtained from factor analyses of the relevant questionnaire items. SB was evaluated as both leisure-time SB and gaming-associated SB. Multiple regression analyses adjusted for age, sex, socioeconomic status, and migration status were used to determine the association between SB, fHC, BMI, and SRH. We found that leisure-time SB was positively associated with fHC, but not with SRH or BMI. Gaming-associated SB was positively associated with fHC and BMI but was negatively associated with SRH. PA was negatively associated with fHC, BMI and SRH. No statistically significant moderating effects were observed. We found that both leisure-time and gaming-associated SB showed statistically significant impacts on health. Although PA is known to be beneficial to health, we conclude that its potential to mitigate the negative effects of SB is limited in young people.

Abstract
BACKGROUND High emotional instability, i.e. neuroticism, is associated with poor mental health. Conversely, traumatic experiences may increase neuroticism. Stressful experiences such as complications are common in the surgical profession, with neurosurgeons being particularly affected. We compared the personality trait neuroticism between physicians in a prospective cross-sectional study. METHODS We used an online survey using the Ten-Item Personality Inventory, an internationally validated measure of the five-factor model of personality dimensions. It was distributed to board-certified physicians, residents, and medical students in several European countries and Canada (n = 5,148). Multivariate linear regression was used to model differences between surgeons, non-surgeons and specialties with occasional surgical interventions with respect to neuroticism, adjusting for gender, age, age squared and their interactions, then testing equality of parameters of adjusted predictions separately and jointly using Wald tests. RESULTS With an expected variability within disciplines, average levels of neuroticism are lower in surgeons than non-surgeons, especially in the first part of their career. However, the course of neuroticism across age follows a quadratic pattern, i.e., an increase after the initial decrease. The acceleration of neuroticism with age is specifically significant in surgeons. Levels of neuroticism are lowest towards mid-career, but exhibit a strong secondary increase towards the end of the surgeons' career. This pattern seems driven by neurosurgeons. CONCLUSION Despite initially lower levels of neuroticism, surgeons suffer a stronger increase of neuroticism together with age. Since, beyond well-being, neuroticism influences professional performance and healthcare systems costs, explanatory studies are mandatory to enlighten causes of this burden.

Abstract
BACKGROUND Lung cancer is the leading cause of cancer death with the majority of cases being non-small cell lung cancer (NSCLC) [1]. A common complication of NSCLC is brain metastasis (BM) [2, 3], where the prognosis remains poor despite new treatments. Real world data complements data gained from clinical trials, providing information on patients excluded from prospective research [4]. However, information from patient notes may prove incomplete and difficult to extract. We developed an algorithm to identify patients in our clinical database with brain metastasis from the electronic health record (EHR). METHODS We retrospectively extracted data from the EHR of patients managed at a large teaching hospital between 2007 and 2018. Using the ICD-10 code C34, for lung cancer, our algorithm used phrases associated with BMs to search the unstructured text of radiology reports. Summary statistics and univariant analysis was performed for overall survival. RESULTS 818 patients were identified as potentially having BM and 453 patients were confirmed on clinical review of their records. The median age of patients was 69 years, 50% were female and 66% had a performance status of >2. 12.2% had an identifiable mutation and 11.5% were identified as PD-L1 positive. In the first line setting, 65% of patients received symptomatic treatment, 23% received systemic anticancer therapy (SACT), 6.1% surgery and 10% radiotherapy, of which 6.5% had external beam and 3.5% stereotactic radiosurgery. Regarding those treated with SACT, 35% had an intracranial response to treatment (3% had complete response, 32% had a partial response). Median survival was 2 months (1.9 - 2.4 months 95% CI). CONCLUSION The real-world prognosis for NSCLC patients with BMs is poor. By using an algorithm, we have reported outcomes on a comprehensive cohort of patients which helps identify those for whom an active treatment approach is appropriate.

Abstract
This study explores how researchers' analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make during data analysis. We coordinated 161 researchers in 73 research teams and observed their research decisions as they used the same data to independently test the same prominent social science hypothesis: that greater immigration reduces support for social policies among the public. In this typical case of social science research, research teams reported both widely diverging numerical findings and substantive conclusions despite identical start conditions. Researchers' expertise, prior beliefs, and expectations barely predict the wide variation in research outcomes. More than 95% of the total variance in numerical results remains unexplained even after qualitative coding of all identifiable decisions in each team's workflow. This reveals a universe of uncertainty that remains hidden when considering a single study in isolation. The idiosyncratic nature of how researchers' results and conclusions varied is a previously underappreciated explanation for why many scientific hypotheses remain contested. These results call for greater epistemic humility and clarity in reporting scientific findings.

Abstract
Application of biocontrol products containing atoxigenic isolates of Aspergillus flavus to reduce aflatoxin content in crops is an effective strategy for managing aflatoxin in several regions throughout the world. We report the development and validation of two aflatoxin biocontrol products, Aflasafe TZ01 and Aflasafe TZ02, for use in maize and groundnut in Tanzania, a country frequently affected by aflatoxin contamination. Each product contains four atoxigenic A. flavus genotypes native and widely distributed in Tanzania. Efficacy tests on maize and groundnut were conducted over two years and in four regions of Tanzania where aflatoxin contamination is prevalent. Application of both products significantly (P<0.05) reduced aflatoxin levels in maize and groundnut in both years and in all districts. No differences were observed in total Aspergillus section Flavi population in treated and untreated fields, revealing that application of the biocontrol products do not alter overall Aspergillus populations in the environment. The results indicate that both products are effective tools for aflatoxin mitigation in groundnut and maize. The products were officially registered in 2018. Currently, there are scale-out and-up efforts of aflatoxin biocontrol products in Tanzania through a private sector company that is making the products available to farmers. Protecting maize and groundnut from aflatoxin contamination in Tanzania can result in health, income, and trade benefits.

Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Abstract
To address the challenges related to the interconnectivity between vial container closure systems and vial transfer devices, pharmaceutical, elastomer, and transfer device manufacturers have formed a working group under the Product Quality Research Institute (PQRI) to establish best practices for the evaluation of the assembly of vial transfer devices and vial systems. As part of the project, the first activity was to quantify the nature and frequency of issues (complaints). To this end, the working group conducted a survey with questionnaires related to categories and numbers of complaints, regions/countries where complaints were received, and the nature of the manufacturers who received the complaints. The survey was distributed to the 16 companies participating in the working group, and 11 companies submitted a response. Besides quantifying and ranking the frequency of issues, the survey determined what issues are common across all companies and what issues may be product-specific or specific by manufacturer. In this article, the analysis and outcomes of the survey will be presented, and the next steps will be discussed.

Abstract
Acute disseminated encephalomyelitis (ADEM) is an autoimmune, central nervous system demyelinating disorder that follows antecedent immunologic challenges, such as infection or vaccination. This study aimed to investigate the potential association between routine childhood vaccinations and ADEM. Children under 7 years of age admitted to the two tertiary level pediatric hospitals in Victoria, Australia with ADEM from 2000-2015 had their clinical information linked to vaccination records from the Australian Childhood Immunization Register. Chart review was undertaken utilizing the Brighton Collaboration ADEM criteria. The self-controlled case-series (SCCS) methodology was employed to determine the relative incidences of ADEM post-vaccination in two risk intervals: 5-28 days and 2-42 days. Forty-six cases were eligible for SCCS analysis with a median age of 3.2 years. Of the forty-six cases, three were vaccine proximate cases and received vaccinations 23, 25 and 28 days before ADEM onset. Two vaccine proximate cases received their 4-year-old scheduled vaccinations (MMR and DTPa-IPV) and one vaccine proximate case the 1-year old scheduled vaccinations (MMR and Hib-MenC). The relative incidence of ADEM during the narrow and broad risk intervals were 1.041 (95% CI 0.323-3.356, p = 0.946) and 0.585 (95% CI 0.182-1.886, p = 0.370) respectively. Sensitivity analyses did not yield any substantial deviations. These results do not provide evidence of an association between vaccinations routinely provided to children aged under 7 years in Australia and the incidence of ADEM. However, these results should be interpreted with caution as the number of ADEM cases identified was limited and further research is warranted.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
BACKGROUND Clinicians in neuroscientific disciplines may present distinct personality profiles. Despite of potential relevance to clinical practice, this has not yet been studied. We therefore aimed to compare personality profiles of physicians working in the three main disciplines of clinical neuroscience, i.e., neurologists, neurosurgeons, and psychiatrists, between each other, across levels of training and to other specialties. METHODS An online survey using the Ten-Item Personality Inventory (TIPI), an internationally validated measure of the five-factor model of personality dimensions, was distributed to board-certified physicians, residents, and medical students in several European countries and Canada. Differences in personality profiles were analyzed using multivariate analysis of variance and canonical linear discriminant analysis on age- and sex-standardized z-scores of personality traits. Single personality traits were analyzed using robust t tests. RESULTS Of the 5148 respondents who completed the survey, 723 indicated the specialties neurology, neurosurgery, or psychiatry. Compared to all other specialties, personality profiles of training and trained physicians in these three main clinical neuroscience disciplines ("NN&P") significantly differed, with significantly higher scores in openness to experience. Within NN&P, there were significant differences in personality profiles, driven by lower neuroticism in neurosurgeons, higher conscientiousness in neurosurgeons and neurologists, and higher agreeableness in psychiatrists. Across levels of training, NN&P personality profiles did not differ significantly. CONCLUSION The distinct clinical neuroscience personality profile is characterized by higher levels of openness to experience compared to non-neuroscience specialties. Despite high variability within each discipline, moderate, but solid differences in the personality profiles of neurologists, neurosurgeons and psychiatrists exist.

Abstract
BACKGROUND Primary biliary cholangitis (PBC) is an autoimmune hepatobiliary disorder characterized by destruction of liver bile ducts leading to intrahepatic cholestasis. It causes intractable pruritus for which ultraviolet (UV)B phototherapy is an experimental treatment when alternative therapies fail. The pathophysiology of cholestatic itch and the mechanism of action of narrowband UVB in this condition remains poorly understood. OBJECTIVES To summarize the current literature and propose testable hypotheses for the mechanism of action of phototherapy in attenuating itch. METHODS A focused PubMed search for articles relating to the pathogenesis of itch in cholestatic disease was performed. A total of 3855 articles were screened and 50 were found suitable for literature review. Evidence from this literature review was combined with author expertise in the area. RESULTS Formulated hypotheses focus on the role of bile salts, autotaxin and specific receptors including G-protein-coupled bile acid receptor, Gpbar1 (also known as TGR5) and the nuclear transcription factor farnesoid X receptor. CONCLUSIONS Several testable mechanisms through which phototherapy may exert its effects are discussed in this review. The next steps are to carry out an objective assessment of the efficacy of phototherapy in cholestatic pruritus, gain further knowledge on the underlying pathways, and subsequently trial its use against current licensed therapies. Such studies could lead to increased mechanistic understanding, identification of novel therapeutic targets and the potential to refine phototherapy protocols, leading to improved control of itch and quality of life in patients with PBC. What's already known about this topic? Primary biliary cholangitis (PBC) is frequently associated with intractable pruritus for which current treatment options are often unsuccessful. Phototherapy is used as an experimental treatment for PBC-associated pruritus when alternative better-studied treatments fail. What does this study add? This study reviews the current literature on the pathophysiology and management of cholestatic pruritus, an area which remains poorly understood. We propose testable hypotheses of the mechanisms behind the attenuation of cholestatic pruritus with phototherapy.

Abstract
BACKGROUND Experiencing cranial surgery under awake conditions may expose patients to considerable psychological strain. METHODS This study aimed to investigate the occurrence and course of psychological sequelae following awake craniotomy (AC) for brain tumors in a series of 20 patients using a broad, validated psychological assessment preoperatively, intraoperatively, postoperatively and a standardized follow-up of 3 months. In addition, the association of the preoperative psychological condition (including, but not limited to, anxiety and fear) with perioperative pain perception and interference was assessed. RESULTS AC did not induce any shift in the median levels of anxiety, depression, and stress symptoms already present prior to the procedure. Furthermore, anxiety and depression were all moderately to strongly associated over time (all P < 0.05). Stress symptoms also correlated positively over all times of measurement. Stress 3 days after surgery was strongly associated with stress 3 months after surgery (P < 0.001), whereas the correlation between preoperative and immediate postoperative stress showed a statistical trend (P = 0.07). Preoperative fear was not related to intraoperative pain, but to pain and its interference with daily activity on the third postoperative day (P < 0.001 and P < 0.01, respectively). CONCLUSIONS Postoperative psychological symptoms clearly correlated with their corresponding preoperative symptoms. Thus, mental health was not negatively affected by the AC experience in our series. Intraoperative fear and pain were not related to the preoperative psychological condition. However, preoperative fear and anxiety were positively related with pain and its interference with daily activity in the immediate postoperative period.

Abstract
AIM To evaluate the safety of the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor alirocumab according to diabetes mellitus status. METHODS Safety data from 14 trials (8-104-week durations) were analysed by treatment (alirocumab or placebo/ezetimibe control) and diabetes status (yes/no, defined by medical history). Adverse event data were assessed using descriptive statistics and Cox models. RESULTS Of the 5234 trial participants, 1554 (29.7%) had diabetes. Overall, treatment-emergent adverse events were similar in the alirocumab and control groups, except for more frequent local injection site reactions with alirocumab. Fewer people with diabetes experienced local injection site reactions [alirocumab, 3.5%, control, 2.9%; hazard ratio 1.24 (95% CI 0.68-2.25)] than those without diabetes [alirocumab, 7.5%; control, 4.9%; hazard ratio 1.51 (95% CI 1.13-2.01)]. Those with diabetes reported a greater number of serious adverse events (alirocumab, 19.4%; control, 19.7%) than those without diabetes (alirocumab, 14.5%; control, 13.5%). In people with diabetes, major adverse cardiac events occurred in 2.7% of alirocumab-treated people [control, 3.3%; hazard ratio 0.74 (95% CI 0.41-1.35)]; in those without diabetes, 1.8% of alirocumab-treated people had major adverse cardiac events [control, 1.7%; hazard ratio 0.95 (95% CI 0.56-1.62)]. Overall, no increase in HbA1c or fasting plasma glucose vs control treatment groups was observed, regardless of diabetes status. CONCLUSION This pooled analysis across 14 trials demonstrated similar safety for alirocumab vs control treatment, irrespective of diabetes status, except for more frequent local injection site reactions with alirocumab. People with diabetes reported fewer local injection site reactions than those without diabetes.

Abstract
Background: Rwanda is a high cervical cancer-burden country, with an age standardized rate (ASR) of cervical cancer incidence of 41.8 cases per 100,000 people in 2012. In the same year, cervical cancer mortality lay at 26.2 deaths per 100,000 people. Aim: To address this burden, Rwanda initiated the vision inspection with acetic acid (VIA) screening-based strategy in 2013 in line with WHO recommendations for low- and middle-income countries. The target audience of the program was set for women between the ages of 30 and 49 and remains today. Here, we describe the implementation status of the program at the primary health care level; health centers and district hospitals in Rwanda. Methods: Integrating into Rwanda's existing health system, the program was purposefully rooted in health centers, with a pathway designed for women who screen positive to be referred to the district hospital for cryotherapy or LEEP, according to the lesions' size. Nurses, midwives and medical officers from health centers and district hospitals are trained through a 10-day curriculum (5 days for theory and 5 days for practice) before initiating the provision of services to clients in routine care. Monitoring of the program is conducted through both quarterly, on-site mentorship and screening indicators that are integrated into Rwanda's Health Management Information System (HMIS), through which facilities report on monthly basis. Results: Since its initiation in August 2013, Rwanda's cervical cancer screening program has been established in 21 of 38 (55%) district hospitals and 256 health centers in their catchment area. Training has been an integral component as well, with at least two nurses/midwives trained at implementing health centers and a medical officer with two nurses/midwives trained on cervical cancer screening and the treatment of precancerous lesions at district hospital. In addition, district hospitals have been equipped with cryotherapy, LEEP, and colposcopy machines. Over this program's implementation three-and-a-half-year course, 38,000 women have been screened for cervical cancer. Conclusion: Using a simple VIA-based strategy, Rwanda has been able to swiftly and effectively increase the number of health facilities implementing cervical cancer screening program. Though additional innovative implementation strategies are still needed to proportionally increase women's screening coverage, these initial steps hold great promise in Rwanda's ability to effectively implement a sustainable cervical cancer screening program.

Abstract
OBJECTIVES Medical practice may attract and possibly enhance distinct personality profiles. We set out to describe the personality profiles of surgical and medical specialties focusing on board-certified physicians. DESIGN Prospective, observational. SETTING Online survey containing the Ten-Item Personality Inventory (TIPI), an internationally validated measure of the Five Factor Model of personality dimensions, distributed to board-certified physicians, residents and medical students in several European countries and Canada. Differences in personality profiles were analysed using multivariate analysis of variance and Canonical Linear Discriminant Analysis on age-standardised and sex-standardised z-scores of the personality traits. Single personality traits were analysed using robust t-tests. PARTICIPANTS The TIPI was completed by 2345 board-certified physicians, 1453 residents and 1350 medical students, who also provided demographic information. RESULTS Normal population and board-certified physicians' personality profiles differed (p<0.001). The latter scored higher on conscientiousness, extraversion and agreeableness, but lower on neuroticism (all p<0.001). There was no difference in openness to experience. Board-certified surgical and medical doctors' personality profiles were also different (p<0.001). Surgeons scored higher on extraversion (p=0.003) and openness to experience (p=0.002), but lower on neuroticism (p<0.001). There was no difference in agreeableness and conscientiousness. These differences in personality profiles were reproduced at other levels of training, that is, in students and training physicians engaging in surgical versus medical practice. CONCLUSION These results indicate the existence of a distinct and consistent average 'physician personality'. Despite high variability within disciplines, there are moderate but solid and reproducible differences between surgical and medical specialties.

Abstract
We ask how employers contribute to unemployment scarring in the recruitment process in the German-speaking part of Switzerland. By drawing on recruitment theories, we aim to better understand how recruiters assess different patterns of unemployment in a job candidate's CV and how this affects the chances of young applicants being considered for a vacancy. We argue that in contexts with tight school-work linkage and highly standardised Vocational Education and Training systems, the detrimental effect of early unemployment depends on how well the applicant's profile matches the requirements of the advertised position. To test this assumption, we surveyed Swiss recruiters who were seeking to fill positions during the time of data collection. We employed a factorial survey experiment that tested how the (un)employment trajectories in hypothetical young job applicants' CV affected their chances of being considered for a real vacancy. Our results show that unemployment decreases the perceived suitability of an applicant for a specific job, which implies there is a scarring effect of unemployment that increases with the duration of being unemployed. But we also found that these effects are moderated by how well the applicant's profile matches the job's requirements. Overall, the worse the match between applicant's profile and the job profile, the smaller are the scarring effects of unemployment. In sum, our findings contribute to the literature by revealing considerable heterogeneity in the scarring effects of unemployment. Our findings further suggest that the scarring effects of unemployment need to be studied with regard to country-specific institutional settings, the applicants' previous education and employment experiences, and the job characteristics.

Abstract
AIM To assess the lipid-lowering efficacy and safety of alirocumab, a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, in people with hypercholesterolaemia and prediabetes at baseline vs people with normoglycaemia at baseline in a pooled analysis of 10 ODYSSEY phase III trials. METHODS People classified as having prediabetes had baseline HbA1c ≥39 mmol/mol (5.7%) and <48 mmol/mol (6.5%), or two baseline fasting plasma glucose values ≥5.6 mmol/l (100 mg/dl) but no more than one fasting plasma glucose value ≥7.0 mmol/l (126 mg/dl), or had specific terms reported in their medical history; people diagnosed with diabetes at baseline were excluded, and the remainder were classified as having normoglycaemia. Participants received alirocumab or control (placebo/ezetimibe) for 24-104 weeks, with maximally tolerated statin in most cases. The primary efficacy endpoint was LDL cholesterol reductions from baseline to week 24 in the intention-to-treat population using the mixed-effect model with a repeated measures approach. RESULTS Reductions in LDL cholesterol from baseline to week 24 with alirocumab were 44.0-61.8% (prediabetes group) and 45.8-59.5% (normoglycaemia group). In both subgroups, LDL cholesterol reductions were generally similar in those with and without baseline triglycerides ≥1.7 mmol/l (150 mg/dl). Alirocumab was not associated with changes in HbA1c or fasting plasma glucose over time in either subgroup (up to 24 months' follow-up). Adverse event rates were generally similar in those with and without prediabetes. CONCLUSIONS Over a mean follow-up of 24-104 weeks, alirocumab treatment resulted in significant LDL cholesterol reductions from baseline that were similar in participants with prediabetes and those with normoglycaemia at baseline, with no effect on glycaemia and a safety profile similar to that of the control.

Abstract
OBJECTIVE To assess the consequences of aneurysmal subarachnoid hemorrhage (aSAH) on sexual pleasure in patients with an otherwise favorable neurologic outcome. METHODS Anonymous, standardized questionnaires concerning sexual function, including the International Index of Erectile Function (IIEF), Female Sexual Function Index (FSFI), and a statement on subjective change in sexual pleasure after aSAH, were completed by 33 patients treated at the Cantonal Hospital St Gallen between 2005 and 2013. All had favorable neurologic outcomes (Glasgow Outcome Scale score 4 or 5). RESULTS Ten patients (31.3%) reported a subjective worsening of sexual pleasure after aSAH. Sexual dysfunction according to FSFI criteria affected 9 of the 19 female patients (47.4%). All 19 women had a hypoactive sexual desire disorder. Erectile dysfunction was present in 7 of the 14 male patients (50%). Patients with World Federation of Neurosurgical Societies (WFNS) grade 2 aSAH were significantly more likely to report a subjective worsening of sexual experience after hemorrhage than those with WFNS grade 1. CONCLUSIONS This is the first known evaluation of sexual health following aSAH with otherwise favorable neurologic outcomes, and confirms that sexual dysfunction is common in this population. Sexual health should be explored during follow-up with these patients.

Abstract
Life satisfaction is an important indicator of successful development. However, adolescents' life satisfaction tends to be relatively unsteady, and environmental influences play a critical role in shaping life satisfaction among adolescents in the transition to young adulthood. Given the paramount importance that education plays in adolescents' lives, adolescents' life satisfaction may vary as a function of school-related stress experience. At the same time, coping resources may help reduce adverse effects of stress on life satisfaction. With this in mind, we examined whether, and to what extent, perceived stress in education and general self-efficacy (a resource that facilitates coping) affect the life satisfaction of adolescents in transition to young adulthood. We distinguished between baseline levels of stress and self-efficacy and within-person change in stress and self-efficacy to determine whether life satisfaction is sensitive to fluctuations in stress and self-efficacy when person-specific levels of stress and self-efficacy are taken into account. Estimating growth curve models on data from a panel study on the life trajectories of compulsory-school leavers (n = 5126, 55.3 % female), we found that baseline levels of stress and self-efficacy, as well as within-person change in stress and self-efficacy, affected adolescents' life satisfaction. Moreover, our results showed that baseline self-efficacy mitigated the negative effect of baseline stress on life satisfaction. These findings improve our understanding of two major psychological determinants of adolescents' life satisfaction and extend our knowledge of life satisfaction trajectories during the transition to young adulthood.

Abstract
AIM The purpose of the study were (i) to screen for cognitive impairment using Mini-Mental Status Examination among three old-age groups based on dwelling types in Chennai, India i.e. residential paid old-age homes, residential free (charitable) homes and home-based community-dwelling residents; (ii) secondly to investigate factors (demographic, psychological, medical and disability) associated with cognitive impairment in the these old-age; (iii) third, to investigate the independent association between cognitive impairment and health-related quality of life (QOL) among elderly across aged care dwelling types. METHODS A total of 499 elderly from three old-age groups were interviewed in this cross-sectional study (173 elderly home-based community-dwellers, 176 paid-home and 150 free-home residents). All the participants were interviewed for their socio-economic condition, medical morbidity, self-reported worry and anxiety, disability and QOL. RESULTS 42.7% free-home elderly residents were found to have cognitive impairment, whereas 32.4% of paid-home and 21.9% of community-dwelling elderly had cognitive impairment. The residents of free-home were less educated, had lower income and reported higher incidence of worry, anxiety, disability and poor QOL than community-dwelling or paid-home residents. Increasing age, low education, female gender, high blood pressure and disability were associated with cognitive impairment. Cognitive impairment had significant negative effect on their health-related QOL (b = -0.10, P = 0.01), independent of age, gender, education, chronic illness and dwelling type. CONCLUSION The burden of cognitive impairment was high in all aged-care dwelling types in urban India; with free charitable home residents being worse affected. Cognitive impairment was associated with disability and poor health-related QOL in these age-care settings.

Abstract
Our studies presented in this report focus on the behavior of NA-CATH, an α-helical cathelicidin antimicrobial peptide, originally discovered in the Naja atra snake. It has demonstrated high potency against gram-positive and gram-negative bacteria with minimal hemolysis. Here we examine the kinetics, behaviors and potential mechanisms of the peptide in the presence of membrane liposome, modeling Escherichia coli, whose membrane exhibits distinct lipid phases. To understand NA-CATH interactions, the role of lipid phases is critical. We test three different lipid compositions to detangle the effect of phase on NA-CATH's activity using a series of leakage experiments. From these studies, we observe that NA-CATH changes from membrane disruption to pore-based lysing, depending on phases and lipid composition. This behavior also plays a major role in its kinetics.

Abstract
Hybridization is a fundamental process in biology and can lead to new evolutionary lineages. However, if the parental taxa involved are rare, difficult decisi- ons may have to be made regarding the conservation of the biological process versus the conservation of the parental taxa. The genus Orchis in Europe is a good example of a group of species in which these types of questions arise as several of the species hybridize where they co-occur. The example used here relates to O. militaris, O. purpurea and O. simia in the anthropomorphic group (so called because the labellum has lobes thought to resemble arms and legs). All three species are widespread in Europe, al- though they are rare in large parts of their ranges, and they have substantial areas of overlap in distribution. All three are rare in Britain, occurring predominantly in south east England. Orchis militaris and O. simia and are only known from two and three natural sites in England, respectively. Orchis purpurea is less rare, but is still geographically localized.
