The use of Lay Mental Health Workers (LMHWs) to tackle the treatment gap in low-resource settings is well established, and although they often receive training, the potential of proper supervision to improve outcomes remains untapped. Indeed, given the strain on expert resources, peer-supervision models based on supervisors' seniority of work experience have significant potential especially in relation to community knowledge and embedding of LMHWs. This study summarizes the evaluation of a pilot program for peer supervision on the basis of Social Cognitive Theories of Self-Efficacy for LMHWs in Kerala, India.

Background & Purpose: Pre-stroke impairment of activities of daily living (ADL) is considered a major determinant for functional outcome after stroke. However, findings are based on studies in stroke patients in which pre-stroke information is gathered retrospectively, with inherent risks of selection and recall bias. The objective of this study was to verify the predictive value of pre-stroke ADL with respect to ADL decline in a large prospective cohort of community dwelling older subjects with known vascular risk factors or vascular disease, thereby minimizing selection and recall bias.

Applying federated learning to combat food fraud in food supply chains.

NPJ Sci Food

September 2023

Wageningen Food Safety Research, Akkermaalsbos 2, 6708 WB, Wageningen, The Netherlands.

Ensuring safe and healthy food is a big challenge due to the complexity of food supply chains and their vulnerability to many internal and external factors, including food fraud. Recent research has shown that Artificial Intelligence (AI) based algorithms, in particularly data driven Bayesian Network (BN) models, are very suitable as a tool to predict future food fraud and hence allowing food producers to take proper actions to avoid that such problems occur. Such models become even more powerful when data can be used from all actors in the supply chain, but data sharing is hampered by different interests, data security and data privacy.

An amplitude analysis of the B^{+}→D_{s}^{+}D_{s}^{-}K^{+} decay is carried out to study for the first time its intermediate resonant contributions, using proton-proton collision data collected with the LHCb detector at center-of-mass energies of 7, 8, and 13 TeV. A near-threshold peaking structure, referred to as X(3960), is observed in the D_{s}^{+}D_{s}^{-} invariant-mass spectrum with significance greater than 12 standard deviations. The mass, width, and the quantum numbers of the structure are measured to be 3956±5±10  MeV, 43±13±8  MeV, and J^{PC}=0^{++}, respectively, where the first uncertainties are statistical and the second systematic.

Establishing causal relationships in observational studies is an important step in research and policy decision making. The association between an exposure and an outcome can be confounded by multiple factors, often making it hard to draw causal conclusions. The co-twin control design (CTCD) is a powerful approach that allows for the investigation of causal effects while controlling for genetic and shared environmental confounding factors.

Background: Smoking-associated DNA methylation levels identified through epigenome-wide association studies (EWASs) are generally ascribed to smoking-reactive mechanisms, but the contribution of a shared genetic predisposition to smoking and DNA methylation levels is typically not accounted for.

Methods: We exploited a strong within-family design, that is, the discordant monozygotic twin design, to study reactiveness of DNA methylation in blood cells to smoking and reversibility of methylation patterns upon quitting smoking. Illumina HumanMethylation450 BeadChip data were available for 769 monozygotic twin pairs (mean age = 36 years, range = 18-78, 70% female), including pairs discordant or concordant for current or former smoking.

The risk of criminal behavior in the elderly and patients with neurodegenerative disease.

Handb Clin Neurol

August 2023

Department Epidemiology and Biostatistics, Amsterdam UMC, Amsterdam, The Netherlands.

Behavioral changes are commonly observed in patients with dementia and can lead to criminal offenses, even without a history of criminal or antisocial behavior. Due to the growth of the aging population, this poses a rising problem to deal with for the criminal justice system and in general for society. Criminal behavior may include minor crimes such as theft or traffic violations, but also serious crimes such as physical abuse, sexual offense, or murder.

Article Synopsis
  • The LHCb experiment measured the production rates of B_{s}^{0} and B^{0} mesons in proton-proton collisions at a high energy of 13 TeV, focusing on events with different levels of particle density.
  • They observed a significant 3.4σ increase in the ratio of B_{s}^{0} to B^{0} mesons at low transverse momenta (below 6 GeV/c) as the number of charged particles in the event increased, but no significant change at higher momenta.
  • The findings suggest that the hadronic medium's density influences B meson production, which aligns with the idea that quark coalescence might be a key process in creating particles during

Phys Rev Lett

August 2023

Department of Physics and Astronomy, University of Manchester, Manchester, United Kingdom.

The first simultaneous test of muon-electron universality using B^{+}→K^{+}ℓ^{+}ℓ^{-} and B^{0}→K^{*0}ℓ^{+}ℓ^{-} decays is performed, in two ranges of the dilepton invariant-mass squared, q^{2}. The analysis uses beauty mesons produced in proton-proton collisions collected with the LHCb detector between 2011 and 2018, corresponding to an integrated luminosity of 9  fb^{-1}. Each of the four lepton universality measurements reported is either the first in the given q^{2} interval or supersedes previous LHCb measurements.

Length of hospital stays and financial incentives: evidence from Dutch rehabilitation centers.

Eur J Health Econ

July 2024

School of Business and Economics, Talma Institute / VU University Amsterdam, Section Health Economics, De Boelelaan 1085, 1081 HV, Amsterdam, The Netherlands.

Non-linear reimbursement contracts in healthcare have been increasingly used to quantify providers' responses to financial incentives. In the present research, we utilize a large one-off increase in the reimbursement of rehabilitation care to assess to what extent providers are willing to modify their treating behavior to maximize profits. In order to disincentivize the use of short inpatient stays for rehabilitation care, Dutch policy-makers have instated a two-part stepwise tariff-schedule.

Impaired Direction Selectivity in the Nucleus of the Optic Tract of Albino Mice.

Invest Ophthalmol Vis Sci

August 2023

Department of Circuits, Structure & Function, Netherlands Institute for Neuroscience, Royal Netherlands Academy of Arts and Sciences, Amsterdam, the Netherlands.

Purpose: Human albinos have a low visual acuity. This is partially due to the presence of spontaneous erroneous eye movements called pendular nystagmus. This nystagmus is present in other albino vertebrates and has been hypothesized to be caused by aberrant wiring of retinal ganglion axons to the nucleus of the optic tract (NOT), a part of the accessory optic system involved in the optokinetic response to visual motion.
