Impact of vocational interests, previous academic experience, gender and age on Situational Judgement Test performance
Situational Judgement Tests (SJTs) are increasingly implemented in medical school admissions. In this paper, we investigate the effects of vocational interests, previous academic experience, gender and age on SJT performance. The SJT was part of the selection process for the Bachelor's degree programme in Medicine at University of Groningen, the Netherlands. All applicants for the academic year 2015-2016 were included and had to choose between learning communities Global Health (n = 126), Sustainable Care (n = 149), Intramural Care (n = 225), or Molecular Medicine (n = 116). This choice was used as a proxy for vocational interest. In addition, all graduate-entry applicants for academic year 2015-2016 (n = 213) were included to examine the effect of previous academic experience on performance. We used MANCOVA analyses with Bonferroni post hoc multiple comparisons tests for applicant performance on a six-scenario SJT. The MANCOVA analyses showed that for all scenarios, the independent variables were significantly related to performance (Pillai's Trace: 0.02-0.47, p <.01). Vocational interest was related to performance on three scenarios (p <.01). Graduate-entry applicants outperformed all other groups on three scenarios (p <.01) and at least one other group on the other three scenarios (p <.01). Female applicants outperformed male applicants on three scenarios (p <.01) and age was positively related to performance on two scenarios (p <.05). A good fit between applicants' vocational interests and SJT scenario was related to better performance, as was previous academic experience. Gender and age were related to performance on SJT scenarios in different settings. Especially the first effect might be helpful in selecting appropriate candidates for areas of health care in which more professionals are needed
Low prevalence of neuropathic-like pain symptoms in long-term controlled acromegaly
Purpose Pain is a common symptom of acromegaly, impairing health-related quality of life (HR-QoL) significantly despite long-term disease remission. Neuropathic-like pain (NP-like) symptoms are invalidating, with great impact on HR-QoL. Studies characterizing or investigating the etiology of pain in acromegaly are scarce. Therefore, we aimed to assess NP-like symptoms in a cohort of controlled acromegaly patients. Methods Forty-four long-term controlled acromegaly patients (aged 62.6 +/- 12.6 years; 56.8% female) were included in this cross-sectional study. NP-like symptoms were assessed using the validated painDETECT questionnaire. Patients were divided in three probability-based NP-like symptoms categories based on the total score (range 0-35): unlikely (= 19). HR-QoL (physical component score (PCS), and mental component score (MCS)), and self-reported pain were assessed using Short Form-36 (SF-36). Potential risk factors were determined using linear regression analyses. Results Self-reported pain was reported by 35 patients (79.5%). Likely NP-like symptoms were present in 4/44 patients (9.1%), and indeterminate NP-like symptoms in 6/44 patients (13.6%). All patients with likely NP-like symptoms were female. Higher painDETECT scores were negatively associated with HR-QoL (PCS: r = - 0.46, P = 0.003; MCS: r = - 0.37, P = 0.018), and SF-36 pain scores (r = - 0.63, P < 0.0001). Female sex was a risk factor for NP-like symptoms. Conclusions Pain was prevalent in controlled acromegaly patients, whereas NP-like symptoms were relatively infrequent, and only observed in females. NP-like symptoms were associated with lower HR-QoL in acromegaly. Since specific analgesic therapy is available, awareness for characterization, increased understanding, and clinical trials regarding neuropathic pain identification and treatment in acromegaly patients are warranted.Clinical epidemiolog
Quality of Pharmaceutical Industry Press Releases Based on Original Research
Background: Press releases are a popular vehicle to disseminate health information to the lay media. While the quality of press releases issued by scientific conferences and medical journals has been questioned, no efforts to assess pharmaceutical industry press releases have been made. Therefore, we sought to systematically examine pharmaceutical company press releases about original research for measures of quality. Methodolgy/Principal Findings: Press releases issued by the ten top selling, international pharmaceutical companies in the year 2005 were selected for evaluation. A total of 1028 electronic press releases were issued and 235 were based on original research. More than half (59%) reported results presented at a scientific meeting. Twenty-one percent of releases were not explicit about the source of original data. While harms or adverse events were commonly cited (76%), study limitations were rarely noted (6%). Almost one-third (29%) of releases did not quantify study results. Studies presented in abstract form were subsequently published within at least 20 months in 53 % of cases. Conclusions: Pharmaceutical company press releases frequently report basic study details. However, readers should be cautioned by the preliminary nature of the data and lack of identified limitations. Methods to improve the reporting and interpretation of drug company press releases are desirable to prevent misleading media coverage
Therapeutic intervention with anti-complement component 5 antibody does not reduce nash but does attenuate atherosclerosis and mif concentrations in ldlr-/-.Leiden mice
Background: Chronic inflammation is an important driver in the progression of nonalcoholic steatohepatitis (NASH) and atherosclerosis. The complement system, one of the first lines of
defense in innate immunity, has been implicated in both diseases. However, the potential therapeutic
value of complement inhibition in the ongoing disease remains unclear. Methods: After 20 weeks of
high-fat diet (HFD) feeding, obese Ldlr-/-.Leiden mice were treated twice a week with an established
anti-C5 antibody (BB5.1) or vehicle control. A separate group of mice was kept on a chow diet
as a healthy reference. After 12 weeks of treatment, NASH was analyzed histopathologically, and
genome-wide hepatic gene expression was analyzed by next-generation sequencing and pathway
analysis. Atherosclerotic lesion area and severity were quantified histopathologically in the aortic
roots. Results: Anti-C5 treatment considerably reduced complement system activity in plasma and
MAC deposition in the liver but did not affect NASH. Anti-C5 did, however, reduce the development
of atherosclerosis, limiting the total lesion size and severity independently of an effect on plasma
cholesterol but with reductions in oxidized LDL (oxLDL) and macrophage migration inhibitory
factor (MIF). Conclusion: We show, for the first time, that treatment with an anti-C5 antibody in
advanced stages of NASH is not sufficient to reduce the disease, while therapeutic intervention
against established atherosclerosis is beneficial to limit further progression
Energy expenditure during egg laying is equal for early and late breeding free-living female great tits
In many bird populations, variation in the timing of reproduction exists but it is not obvious how this variation is maintained as timing has substantial fitness consequences. Daily energy expenditure (DEE) during the egg laying period increases with decreasing temperatures and thus perhaps only females that can produce eggs at low energetic cost will lay early in the season, at low temperatures. We tested whether late laying females have a higher daily energy expenditure during egg laying than early laying females in 43 great tits (Parus major), by comparing on the same day the DEE of early females late in their laying sequence with DEE of late females early in their egg laying sequence. We also validated the assumption that there are no within female differences in DEE within the egg laying sequence. We found a negative effect of temperature and a positive effect of female body mass on DEE but no evidence for differences in DEE between early and late laying females. However, costs incurred during egg laying may have carry-over effects later in the breeding cycle and if such carry-over effects differ for early and late laying females this could contribute to the maintenance of phenotypic variation in laying dates
On the theory of pressure broadening
A rederivation of a formula due to Lenz is given, assuming the perturbing potential to be a stationary stochastic process. The derivation of this formula from quantum-mechanics by Bloom and Margenau has been improved in the same way. The calculations result in approximately the same formulas as those already known
