Polypharmacy in people with dementia: Associations with adverse health outcomes
2018
Polypharmacy has been linked to higher risks of hospitalisation and death in community samples. It is commonly present in people with dementia but these risks have rarely been studied in this population. We aimed to investigate associations between polypharmacy and emergency department attendance, any and unplanned hospitalisation, and mortality in patients with dementia. Using a large mental health care database in South London, linked to hospitalisation and mortality data, we assembled a retrospective cohort of patients diagnosed with dementia. We ascertained number of medications prescribed at the time of dementia diagnosis and conducted multivariate Cox regression analyses. Of 4668 pati…
The contribution of cannabis use to variation in the incidence of psychotic disorder across Europe (EU-GEI): a multicentre case-control study.
2019
Background: Cannabis use is associated with increased risk of later psychotic disorder but whether it affects incidence of the disorder remains unclear. We aimed to identify patterns of cannabis use with the strongest effect on odds of psychotic disorder across Europe and explore whether differences in such patterns contribute to variations in the incidence rates of psychotic disorder. Methods: We included patients aged 18–64 years who presented to psychiatric services in 11 sites across Europe and Brazil with first-episode psychosis and recruited controls representative of the local populations. We applied adjusted logistic regression models to the data to estimate which patterns of canna…
Tower of London test: a comparison between conventional statistic approach and modelling based on artificial neural network in differentiating fronto…
2011
The early differentiation of Alzheimer’s disease (AD) from frontotemporal dementia (FTD) may be difficult. The Tower of London (ToL), thought to assess executive functions such as planning and visuo-spatial working memory, could help in this purpose. Twentytwo Dementia Centers consecutively recruited patients with early FTD or AD. ToL performances of these groups were analyzed using both the conventional statistical approaches and the Artificial Neural Networks (ANNs) modelling. Ninety-four non aphasic FTD and 160 AD patients were recruited. ToL Accuracy Score (AS) significantly (p < 0.05) The use of hidden information contained in the different items of ToL and the non linear processing of…
Państwo Islamskie w perspektywie czasopisma "London Review of Books" (wybrane zagadnienia)
2016
Celem artykułu jest analiza funkcjonowania Państwa Islamskiego w ujęciu prestiżowego angielskiego dwutygodnika „London Review of Books”. Tekst składa się z czterech części. Najpierw omawia się okoliczności narastania zjawiska sunnickiego dżihadyzmu w Iraku po kierowanej przez Stany Zjednoczone inwazji w 2003 r. Następnie zwraca się uwagę na relacje reżimu partii Baas w Syrii z sunnickimi ekstremistami. W kolejnej części zaś na kwestię użycia broni chemicznej w Syrii w 2013 r. W ostatnim rozdziale opisano dwuznaczną rolę Turcji w konfliktach w Iraku i Syrii. W podsumowaniu zawarto wnioski z rozważań.
Carbon nanorings: A challenge to theoretical chemistry
2006
High-level quantum-chemical methods show that the binding in the inclusion complex of hexamethylbenzene (HMB) in 6-cycloparaphenilacetylene (6-CPPA) cannot be explained only in terms of electrostatic interactions - caused by the polarization associated to curved Ï-conjugated systems - and the inclusion of dispersion forces is definitely needed. The theoretical description of van der Waals interactions is notoriously complicated and in fact some DFT methods cannot even predict the existence of the relatively small supramolecular nanoring studied here. However, ab initio MP2 calculations agree with experimental data and show that, in the considered complex, the HMB fragment is placed at the …

Risk of Hospitalized Falls and Hip Fractures in 22,103 Older Adults Receiving Mental Health Care vs 161,603 Controls: A Large Cohort Study.
2020
Abstract: Objectives: To investigate the risk of hospitalized fall or hip fracture among older adults using mental health services. Design: Retrospective cohort study. Setting and Participants: Residents of a South London catchment aged >60 years receiving specialist mental health care between 2008 and 2016. Measures: Falls and/or a hip fracture leading to hospitalization were ascertained from linked national records. Incidence rates and incidence rate ratios (IRRs) were age- and gender-standardized to the catchment population. Multivariable survival analyses were applied investigating falls and/or hip fractures as outcomes. Results: In 22,103 older adults, incidence rates were 60.1 per 100…
London equation of state for a quantum-hard-sphere system
1994
The London analytical interpolation equation between zero and packing densities for the ground-state energy of a many-boson hard-sphere system is corrected for the reduced mass of a pair of particles in a ``sphere-of-influence'' picture. It is thus brought into good agreement with computer simulations and with experimental results extrapolated out to close packing.
Discriminating short-range from van der Waals forces using total force data in noncontact atomic force microscopy
2014
Noncontact atomic force microscopy (NC-AFM) features the measurement of forces with highest spatial resolution and sensitivity, resolving forces of the order of pico-Newtons with submolecular resolution. However, the measured total force is a mixture composed of various interactions. While some interactions such as electrostatic or magnetic forces can be excluded by a careful design of the experiment, the subtraction of van der Waals forces, which mainly originate from London dispersion interactions between the macroscopic tip shank and the bulk sample, remains a challenge. We present the determination of the inherently present van der Waals forces in total interaction force data from fitti…
Kulisy niedoszłego procesu sądowego Stowarzyszenia Polskich Kombatantów w Wielkiej Brytanii z "Tygodnikiem Polskim" w latach 1948-1949
2013
In 1948 members of the Polish Ex-Combatants Association charged the editor of Tygodnik Polski published by the Polish People’s Republic Embassy in London with slander. Eventually, there was no trial, and the dispute ended in 1949 with an settlement. Instead the embassy in London had to pay a large sum as compensation.
