Background: Depression and anxiety are the most prevalent mental health difficulties in the workplace, costing the global economy $1 trillion each year. Evidence indicates that symptoms may be reduced by interventions in the workplace. This paper is the first to systematically review psychosocial interventions for depression, anxiety, and suicidal ideation and behaviours in small-to medium-size enterprises (SMEs).
Methods: A systematic search following PRISMA guidelines, registered in PROSPERO (CRD42020156275), was conducted for psychosocial interventions targeting depression, anxiety, and suicidal ideation/behaviour in SMEs. The PubMed, PsycINFO, Scopus, and two specific occupational health databases were searched, as well as four databases for grey literature, without time limit until 2nd December 2019.
Results: In total, 1283 records were identified, 70 were retained for full-text screening, and seven met the inclusion criteria: three randomised controlled trials (RCTs), three before and after designs and one non-randomised trial, comprising 5111 participants. Study quality was low to moderate according to the Quality Assessment Tool for Quantitative Studies. Five studies showed a reduction in depression and anxiety symptoms using techniques based on cognitive behavioural therapy (CBT), two reported no significant change.
Limitations: Low number and high heterogeneity of interventions and outcomes, high attrition and lack of rigorous RCTs.
Conclusions: Preliminary evidence indicates CBT-based interventions can be effective in targeting symptoms of depression and anxiety in SME employees. There may be unique challenges to implementing programmes in SMEs. Further research is needed in this important area.

Background: Using data from the COHERE collaboration, we investigated whether primary prophylaxis for pneumocystis pneumonia (PcP) might be withheld in all patients on antiretroviral therapy (ART) with suppressed plasma human immunodeficiency virus (HIV) RNA (≤400 copies/mL), irrespective of CD4 count.
Methods: We implemented an established causal inference approach whereby observational data are used to emulate a randomized trial. Patients taking PcP prophylaxis were eligible for the emulated trial if their CD4 count was ≤200 cells/µL in line with existing recommendations. We compared the following 2 strategies for stopping prophylaxis: (1) when CD4 count was >200 cells/µL for >3 months or (2) when the patient was virologically suppressed (2 consecutive HIV RNA ≤400 copies/mL). Patients were artificially censored if they did not comply with these stopping rules. We estimated the risk of primary PcP in patients on ART, using the hazard ratio (HR) to compare the stopping strategies by fitting a pooled logistic model, including inverse probability weights to adjust for the selection bias introduced by the artificial censoring.
Results: A total of 4813 patients (10 324 person-years) complied with eligibility conditions for the emulated trial. With primary PcP diagnosis as an endpoint, the adjusted HR (aHR) indicated a slightly lower, but not statistically significant, different risk for the strategy based on viral suppression alone compared with the existing guidelines (aHR, .8; 95% confidence interval, .6–1.1; P = .2).
Conclusions: This study suggests that primary PcP prophylaxis might be safely withheld in confirmed virologically suppressed patients on ART, regardless of their CD4 count.
In Kindertageseinrichtungen und Schulen wird dem pädagogischen Personal in Bezug auf Sprachförderung ein hoher Qualifizierungsbedarf attestiert; zugleich gibt es wenig gesichertes empirisches Wissen über die Wirkungen entsprechender Fortbildungen. Das Fortbildungsangebot und die Teilnehmenden sind heterogen. Um die Heterogenität der Teilnehmenden zu entschlüsseln, wurden im BiSS-Evaluationsprojekt „SPRÜNGE“ (Sprachförderung im Übergang Kindergarten – Grundschule evaluieren) auf Grundlage einer Typenbildung von N = 27 Fach- und Lehrkräften Unterschiede in ihren Sprachförderkompetenzen und im Fortbildungsbesuch empirisch-quantitativ mittels des Online-Tests SprachKoPF überprüft und für zwei Sprachfördertypen ihre handlungsleitenden Orientierungen in Bezug auf die Wirkungen von Fortbildungen rekonstruiert. Bei diesen beiden, stark fortgebildeten Sprachfördertypen konnten differenzierbare Deutungen zu den Wirkungen von Fortbildungen herausgearbeitet werden, wobei einerseits eine stärkere Kita-Orientierung und andererseits eine stärkere Schulorientierung als (implizite) Referenz deutlich wird. Zudem ließen sich Gelingensbedingungen von Fortbildungen wie „Praxisrelevanz“, die als allgemeingültig angenommen werden, typenspezifisch ausdifferenzieren. Mit der multiperspektivischen Untersuchung der differentiellen Wirkungen von Fortbildungen leistet das Projekt einen explorativen Beitrag zu einer quantitativ und qualitativ ausgerichteten Wirkungsforschung am Übergang Kita-Grundschule.
The formation of amyloid-β oligomers plays a key role in the onset of Alzheimer’s disease. We investigated the aggregation of amyloid-β oligomers by mass spectrometry and ion mobility spectrometry, revealing those structural properties, which lead to the formation of mature fibrils. We can show that the arrangement of the first oligomers is crucial for the topology of the resulting species, leading to the formation of non-toxic aggregates or fibrils.
