The first synthesis of well-defined poly(methylene-co-1,1-diphenylpropenenylene) (C1-co-C1'), equivalent to poly(ethylene-co-diphenylbutadiene) copolymer was accomplished by C1 copolymerization of novel diphenylpropenyl triphenyl arsonium ylides (Ph2AY) and dimethylsulfoxonium methylide (Me2SY) using B-thexylborepane as an initiator. All polymerization conditions, including feed ratio, temperature, and reaction time, were optimized. A series of photoluminescent poly(ethylene-co-diphenylbutadiene) were synthesized at different feed ratios, opening a new synthetic horizon for poly(ethylene-co-disubstitutedbutadiene)...

Artificial intelligence (AI) algorithms are prone to bias at multiple stages of model development, with potential for exacerbating health disparities. However, bias in imaging AI is a complex topic that encompasses multiple coexisting definitions. Bias may refer to unequal preference to a person or group owing to preexisting attitudes or beliefs, either intentional or unintentional. However, cognitive bias refers to systematic deviation from objective judgment due to reliance on heuristics, and statistical bias refers to differences between true and expected values, commonly manifesting as systematic error in model prediction (ie, a model with output unrepresentative of real-world conditions)...

Artificial intelligence (AI) has seen significant progress in medical diagnostics, particularly in image and video analysis. This review focuses on the application of AI in analyzing in vivo confocal microscopy (IVCM) images for corneal diseases. The cornea, as an exposed and delicate part of the body, necessitates the precise diagnoses of various conditions. Convolutional neural networks (CNNs), a key component of deep learning, are a powerful tool for image data analysis. This review highlights AI applications in diagnosing keratitis, dry eye disease, and diabetic corneal neuropathy...

OBJECTIVES: We reviewed literature examining substance use among sexual and gender minorities (SGM) living in the former Soviet Union (USSR) nations. METHODS: Searches were conducted across five databases (PubMed, SocINDEX, CINAHL, PscyInfo, LGBTQ + Source) to identify peer-reviewed literature. RESULTS: Across 19 studies, high hazardous substance use prevalence was documented. Substance use was correlated with (a) sexual health and behaviors and (b) mental wellbeing and the use of other substances...

Background: Incisor retraction is often a crucial phase in ongoing orthodontic treatment, with significant implications for alveolar remodeling mechanisms. There are two prevailing theories which seek to explain this. According to the first, teeth move with the bone, while according to the second, teeth move within the bone. This systematic review seeks to assess morphometric changes in the maxillary alveolar process resulting from incisor retraction following premolar extraction and to evaluate the potential for bone remodeling associated with orthodontic movement...

BACKGROUND: Lymphadenopathy is a common finding in clinical practice. The cause of enlarged nodes on clinical examination alone is challenging and there may be multiple reasons for this enlargement. It may become enlarged due to stimulation by infectious agents or the involvement of metastasis or malignant diseases, such as lymphoma. OBJECTIVE: The aim of the study was to investigate the diagnostic role of fine needle aspiration cytology of lymph nodes in metastatic cancer and lymphoma...

Fungi are often considered a delicacy and are primarily cultivated and harvested, although numerous species are responsible for intoxication due to toxin content. Foodborne diseases are a significant public health concern, causing approximately 420,000 deaths and 600 million morbidities yearly, of which mushroom poisoning is one of the leading causes. Epidemiological data on non-cultivated mushroom poisoning in individual countries are often unrepresentative, as intoxication rarely requires emergency intervention...

BACKGROUND: Most COVID-19-related mental health research focused on average levels of mental health parameters in the general population. However, considering heterogenous groups and their long-term responses could deepen our understanding of mental health during community crises. This four-wave study aimed to (1) identify subgroups with different trajectories of depressive and anxiety symptoms in the German general population, and (2) investigate associated risk factors. METHODS: We analyzed self-report data from N = 1257 German adults participating in a European cohort study, assessed in summer 2020 (T1), and at 6 (T2), 12 (T3), and 30 months (T4)...

The evaporative emissions of anthropogenic volatile organic compounds (AVOCs) are sensitive to ambient temperature. This sensitivity forms an air pollution-meteorology connection that has not been assessed on a regional scale. We parametrized the temperature dependence of evaporative AVOC fluxes in a regional air quality model and evaluated the impacts on surface ozone in the Beijing-Tianjin-Hebei (BTH) area of China during the summer of 2017. The temperature dependency of AVOC emissions drove an enhanced simulated ozone-temperature sensitivity of 1...

SUMMARYThe World Health Organisation's 2022 AWaRe Book provides guidance for the use of 39 antibiotics to treat 35 infections in primary healthcare and hospital facilities. We review the evidence underpinning suggested dosing regimens. Few ( n = 18) population pharmacokinetic studies exist for key oral AWaRe antibiotics, largely conducted in homogenous and unrepresentative populations hindering robust estimates of drug exposures. Databases of minimum inhibitory concentration distributions are limited, especially for community pathogen-antibiotic combinations...

The Bronze Age zooarchaeological research for the interior and other regions of the Iberian Peninsula is currently limited. Despite several sites with known zooarchaeological profiles from the period, the main issue is that most of these derive from fragmentary and unrepresentative faunal records or are biased profiles from old excavations. New work has yielded novel zooarchaeological results in recent years that could help fill the existing zooarchaeological information gap in the Iberian inland, particularly in the Middle Tagus Valley...

IMPORTANCE: Occupational therapists often address financial occupations of clients with acquired functional impairments who experience challenges with financial capability (FC). OBJECTIVE: To explore the intervention literature aimed at improving FC in five diagnostic adult populations. DATA SOURCES: MEDLINE, CINAHL, PsycInfo, EconLit, and EMBASE; researchers also completed backward and forward citation searching and contacted expert authors...

PURPOSE: Understanding an artificial intelligence (AI) model's ability to generalize to its target population is critical to ensuring the safe and effective usage of AI in medical devices. A traditional generalizability assessment relies on the availability of large, diverse datasets, which are difficult to obtain in many medical imaging applications. We present an approach for enhanced generalizability assessment by examining the decision space beyond the available testing data distribution...

The usage and disposal of highly abundant single-use and multilayered plastics contribute to significant ecological problems. The thermochemical recovery of these plastics to useful products and chemicals provides opportunity for positive economic and environmental impacts. Most previous research use idealised and unrepresentative feedstocks. To address this, various mixed waste plastics collected from the rejected fraction of a municipal waste recovery facility in Ghana were pyrolyzed at varying temperatures of 450, 500 and 550 °C and their yields compared...

Low back pain (LBP) significantly affects global health, with associated detrimental outcomes such as physical impairment, emotional distress, and exacerbated mental health symptoms. This study evaluated the representation of marginalized groups, including racialized, gender minority, pregnant/lactating, and elderly individuals in randomized controlled trials (RCTs) for pharmacological interventions treating LBP from 2011 to 2020. We searched Embase, MEDLINE, and CINAHL in December 2021, and 139 studies were eligible...

Bulk RNA-seq experiments, commonly used to discern gene expression changes across conditions, often neglect critical cell type-specific information due to their focus on average transcript abundance. Recognizing cell type contribution is crucial to understanding phenotype and disease variations. The advent of single-cell RNA sequencing has allowed detailed examination of cellular heterogeneity; however, the cost and analytic caveat prohibits such sequencing for a large number of samples. We introduce a novel deconvolution approach, SECRET, that employs cell type-specific gene expression profiles from single-cell RNA-seq to accurately estimate cell type proportions from bulk RNA-seq data...

Caring for unrepresented patients encompasses legal, ethical, and moral challenges regarding decision-making, consent, the patient's values, wishes, best interest, and the healthcare team's professional integrity and autonomy. In this article, I consider the impact of the aging population and the effects of the social determinants of health and suggest that without preventive intervention, the number of unrepresented patients will continue to increase. The health, social, and legal risk factors for becoming unrepresented require a multidisciplinary response...

IMPORTANCE: Representativeness of populations within neonatal clinical trials is crucial to moving the field forward. Although racial and ethnic disparities in research inclusion are well documented in other fields, they are poorly described within neonatology. OBJECTIVE: To describe the race and ethnicity of infants included in a sample of recent US neonatal clinical trials and the variability in this reporting. EVIDENCE REVIEW: A systematic search of US neonatal clinical trials entered into Cochrane CENTRAL 2017 to 2021 was conducted...
