Data-Driven Cutoff Selection for the Patient Health Questionnaire-9 Depression Screening Tool.

JAMA Netw Open

November 2024

Department of Epidemiology, Biostatistics and Occupational Health, McGill University, Montréal, Québec, Canada.

Article Synopsis
  • The study investigates how using small datasets to select an optimal cutoff score for the Patient Health Questionnaire-9 (PHQ-9) can lead to inaccurate results.
  • Researchers evaluated whether data-driven methods for cutoff selection resulted in scores that were significantly different from the true population optimal score and if these methods produced biased accuracy estimates.
  • Findings showed that many small studies frequently failed to identify the correct optimal cutoff score, particularly in smaller samples, leading to an overestimation of test sensitivity.

Advances in flexible ionic thermal sensors: present and perspectives.

Nanoscale

December 2024

Department of Mechanical and Automation Engineering, The Chinese University of Hong Kong, Shatin, New Territories, Hong Kong Special Administrative Region, China.

Ionic thermal sensors (ITSs) represent a promising frontier in sensing technology, offering unique advantages over conventional electronic sensors. Comprising a polymer matrix and electrolyte, these sensors possess inherent flexibility, stretchability, and biocompatibility, allowing them to establish stable and intimate contact with soft surfaces without inducing mechanical or thermal stress. Through an ion migration/dissociation mechanism similar to biosensing, ITSs ensure low impedance contact and high sensitivity, especially in physiological monitoring applications.

This study examined how Eucommia ulmoides flavonoids (EUF) protect against intestinal oxidative stress induced by deoxynivalenol (DON) in weaned piglets. Forty weaned piglets were randomly assigned to four dietary groups for a period of 14 days. The piglets were fed a control diet (Control) or the Control diet supplemented with 100 mg EUF/kg (EUF group), 4 mg DON/kg diet (DON group) or both (EUF+DON group) in a 2×2 factorial design.

Article Synopsis
  • - The study analyzed 3847 patients who suffered from a transient ischemic attack or minor ischemic stroke, focusing on those without traditional risk factors (like hypertension and diabetes) to compare their outcomes with those who did have risk factors.
  • - After one year, the risk of major cardiovascular events (MACE) was similar between the two groups, but after five years, those without traditional risk factors had a significantly lower risk of MACE (7.9% vs 13.9%).
  • - In patients without traditional risk factors, arterial stenosis was identified as a critical predictor for MACE, indicating that while their long-term risk was lower, they were not entirely without risk.

Ion implantation is widely utilised for the modification of inorganic semiconductors; however, the technique has not been extensively applied to lead halide perovskites. In this report, we demonstrate the modification of the optical properties of caesium lead bromide (CsPbBr) thin films via noble gas ion implantation. We observed that the photoluminescence (PL) lifetimes of CsPbBrthin films can be doubled by low fluences (<1 × 10at·cm) of ion implantation with an acceleration voltage of 20 keV.

Electronic address:

Objectives: Cognitive frailty is characterized by concurrent physical frailty and mild cognitive impairment and is associated with increased risk of falls. Exercise is an evidence-based strategy to prevent falls, but whether exercise reduces falls in people with cognitive frailty is unknown. We examined the effects of home-based exercise on subsequent falls among community-dwelling older adults with cognitive frailty who have previously fallen.

Mental stress issues are emerging among residents of modern cities. Among environmental factors associated with stress mitigation, greenspace has consistently been shown to have significant stress-reducing properties. However, the temporality of greenspace exposure, particularly the cumulative threshold effect in urban environments, has been largely neglected in past studies.

January 2025

CAS Key Laboratory of Mechanical Behavior and Design of Materials, Department of Precision Machinery and Instrumentation, University of Science and Technology of China, Hefei, 230026, China.

Infrared (IR) radiation thermography is extensively utilized in diverse fields due to its non-contact capability. Nevertheless, its effectiveness is often compromised by the significant emissivity variations among different objects, limiting its application to specific setups or focused object types. Colorimetric thermography is introduced as an alternative emissivity-independent method of radiation thermometry.

Earlier research suggested that psychotic experiences (PEs), the extended-psychosis phenotype, are associated with cognitive impairment. Recent studies, however, revealed more mixed findings, and patterns and magnitude of cognitive deficits in PEs remain uncertain. We aimed to systematically review and quantitatively synthesize estimates of cognitive functioning covering a wide array of domains in individuals with versus without PEs.

Glioblastoma (GBM) immunotherapy is particularly challenging due to the pro-tumorigenic microenvironment, marked by low levels and inactive immune cells. Toll-like receptor (TLR) agonists have emerged as potent immune adjuvants but failed to show improved outcomes in clinical trials when administered as a monotherapy. We hypothesize that a combined nanoparticulate formulation of TLR agonist and immunogenic cell death-inducing drug (doxorubicin) will synergize to induce improved GBM immunotherapy.

Chemotherapy-induced peripheral neuropathy (CIPN) and its related pain are common challenges for patients receiving oxaliplatin chemotherapy. Oxaliplatin accumulation in dorsal root ganglion (DRGs) is known to impair gene transcription by epigenetic dysregulation. We hypothesized that sodium butyrate, a pro-resolution short-chain fatty acid, inhibited histone acetylation in DRGs and abolished K channel dysregulation-induced neuronal hyperexcitability after oxaliplatin treatment.
