Aims: To document and share experiences, challenges and lessons learned from the use of digital health interventions (DHIs) for noncommunicable disease (NCD) service delivery during the COVID-19 pandemic in the Eastern Mediterranean Region (EMR).

Methods: We conducted a documentary research on the use of DHIs for continuity of NCD services during the COVID-19 pandemic in EMR.

Cognitive maps and schizophrenia.

Structured internal representations ('cognitive maps') shape cognition, from imagining the future and counterfactual past, to transferring knowledge to new settings. Our understanding of how such representations are formed and maintained in biological and artificial neural networks has grown enormously. The cognitive mapping hypothesis of schizophrenia extends this enquiry to psychiatry, proposing that diverse symptoms - from delusions to conceptual disorganization - stem from abnormalities in how the brain forms structured representations.

Does Social Media Enhance Rhinoplasty Desire and its Recovery Period: A Saudi Retrospective Study.

Rhinoplasty, which reconstructs the shape and size of the nose, is the most frequently performed cosmetic surgery procedure. Research indicates that social media is the leading influence motivating individuals to undergo rhinoplasty. Thus, we aimed to evaluate the effect of social media on the desire for rhinoplasty and to establish whether (and if so, how) social media enhances the recovery period after rhinoplasty.

A supervised machine learning model to select a cost-effective directional drilling tool.

With the increased directional drilling activities in the oil and gas industry, combined with the digital revolution amongst all industry aspects, the need became high to optimize all planning and operational drilling activities. One important step in planning a directional well is to select a directional tool that can deliver the well in a cost-effective manner. Rotary steerable systems (RSS) and positive displacement mud motors (PDM) are the two widely used tools, each with distinct advantages: RSS excels in hole cleaning, sticking avoidance and hole quality in general, while PDM offers versatility and lower operating costs.

A Common Longitudinal Intensive Care Unit data Format (CLIF) to enable multi-institutional federated critical illness research.

Background: Critical illness, or acute organ failure requiring life support, threatens over five million American lives annually. Electronic health record (EHR) data are a source of granular information that could generate crucial insights into the nature and optimal treatment of critical illness. However, data management, security, and standardization are barriers to large-scale critical illness EHR studies.

Enhancing Sensitivity in Nucleic Acid Detection via Collaborative Multiple Catalytic Cores in DNAzyme Nanomachines.

We introduce a multicore DNA nanomachine (MDNM), utilizing four binary DNAzymes for nucleic acid detection without the need for a preamplification step. This innovation remarkably yields a reduction in limit of detection (LOD), over 5-fold, as compared to single-core systems. This reduces the required test time thus highlighting the potential of MDNM in advancing nucleic acid detection.

Psychosis as a disorder of muscarinic signalling: psychopathology and pharmacology.

Dopaminergic receptor antagonism is a crucial component of all licensed treatments for psychosis, and dopamine dysfunction has been central to pathophysiological models of psychotic symptoms. Some clinical trials, however, indicate that drugs that act through muscarinic receptor agonism can also be effective in treating psychosis, potentially implicating muscarinic abnormalities in the pathophysiology of psychosis. Here, we discuss understanding of the central muscarinic system, and we examine preclinical, behavioural, post-mortem, and neuroimaging evidence for its involvement in psychosis.
