Objective This study aims to discuss a statistically reasonable inclusion of additional questions in the Menopause Rating Scale II (MRS II) for daily use in clinical practice.Methods Retrospective data analysis was performed (cantonal ethics committee No. 2016-01179). The MRS II was extended with the parameters 'changes in weight', 'headaches', 'skin changes', 'changes in hair growth', 'hair loss', and whether therapy was desired. Data from 419 women seeking medical advice in our menopause center were collected between April 2009 and April 2017. Cronbach's alpha was used to measure internal consistency of the extended questionnaire.Results For the conventional MRS II (N = 340 of 419, 81.1%), the internal consistency measured with Cronbach's alpha increased from 0.805 to 0.820 considering 'changes in weight' (N = 237, 56.6%), to 0.815 considering 'headaches' (N = 247, 58.9%), and to 0.815 considering 'skin changes' (N = 236, 56.3%) if these additional parameters were added separately. Cronbach's alpha increased from 0.805 to 0.835 (N = 224, 53.5%) if these parameters were added at once. Desire for therapy varied between 42.1% for 'changes in hair growth' (N = 38, 9.1%) and 60.6% for 'hair loss' (N = 33, 7.9%).Conclusion We suggest including the items 'changes in weight', 'headaches', and 'skin changes' in the MRS II as our results show even higher internal consistency with these symptoms and as the wish for therapy was high.A large number of methods of factor rotation are available in the literature, but the development of formal criteria by which to compare them is an understudied field of research. One possible criterion is the Thurstonian concept of "factorial invariance", which was applied by Kaiser to the varimax rotation method in 1958 and has been subsequently neglected. In the present study, we propose two conditions for establishing whether a method satisfies factorial invariance, and we apply them to 11 orthogonal rotation methods. The results show that 3 methods do not exhibit factorial invariance under either condition, 3 are invariant under one but not the other, and 5 are invariant under both. Varimax rotation is one of the 5 methods that satisfy factorial invariance under both conditions and is the only method that satisfies the invariance condition originally advocated by Kaiser in 1958. From this perspective, it appears that varimax rotation is the method that best ensures factorial invariance.The COVID-19 pandemic has accelerated the pace of research from its routine marathon to a sprint, and this can increase the risk of both human error (mistakes) as well as research misconduct. In an effort to save time, researchers can be tempted to 'cut corners', discount ethical complexity, or use methods and approaches that fall outside of good research practice. Ethically, it is vital that research outputs during a pandemic be robust because clinical decision-making may reflect on these research results. Luxembourg, while a small European nation, is known for its well-ranked global research and innovation. Accordingly, Luxembourg's national organization for research integrity has taken several proactive measures to help researchers nationally and globally, foster robust research. This paper reports on these measures and encourages other nations to similarly assist the research community.Pneumocephalus is usually induced by trauma, infections, tumors of the skull base, and surgical interventions. Spontaneous pneumocephalus occurs due to a defect in the temporal bone with no obvious cause. Few cases have been reported with spontaneous otogenic pneumocephalus. However, delayed postoperative pneumocephalus is rarely reported in the literature. Here, we present a case of otogenic pneumocephalus through Eustachian tube (ET) preceded by nose blowing 10 days after surgical treatment of meningoencephalocele of the right middle ear (ME) cleft and reconstruction of tegmen and dural defects. Pneumocephalus was provoked by decreased intracranial pressure (ICP) secondary to placement of lumbar drain, which caused direct communication between unsutured dural defect and the defective posterior wall of external auditory canal skin. A revision surgery of combined transmastoid/middle cranial fossa approach was performed for intracranial decompression followed by appropriate closure by suturing the dura, obliterating the ET and ME.Increasing evidence have demonstrated that dysregulated alternative splicing (AS) events promoted tumor development and was correlated with worse prognosis in the context of certain malignancies. Nevertheless, a comprehensive examination of the prognosis role of AS events in acute myeloid leukemia (AML) has not yet been illuminated. In this study, univariate and multivariate Cox regression analysis were used to identify survival-related AS events and independent prognostic predictors. The interaction between splicing factors (SFs) and AS events was visualized by Cytoscape. A total of 3013 survival-associated AS events in 1977 genes were screened in 151 AML patients. Interestingly, the majority (2031 events) were revealed to be protective factors. Furthermore, the prediction models were constructed for each type of AS and all of them displayed good performance in predicting prognosis, considering their area under curve values of the receiver operating characteristic were all above 0.7. Notably, the splicing regulatory network displayed the underlying interaction networks between SFs and AS events. Taken together, our study demonstrated the survival-related AS events in AML and uncovered the possible association between SFs and prognostic AS events, which provide new prognostic biomarkers and aid to develop novel targets for AML therapy.Finite element (FE) models can unravel the link between intervertebral disc (IVD) degeneration and its mechanical behaviour. Nucleotomy may provide the data required for model verification. Three human IVDs were scanned with MRI and tested in multiple loading scenarios, prior and post nucleotomy. The resulting data was used to generate, calibrate, and verify the FE models. selleck inhibitor Nucleotomy increased the experimental range of motion by 26%, a result reproduced by the FE simulation within a 5% error. This work demonstrates the ability of FE models to reproduce the mechanical compliance of human IVDs prior and post nucleotomy.
