Biomedical contraceptives and their association with condom use consistency among female sex workers in China: results from a national cross-sectional study.

Ann Epidemiol 2022 Aug 7. Epub 2022 Aug 7.

Division of Epidemiology and Community Health, University of Minnesota Twin Cities, 1300 S 2nd St # 300, Minneapolis, MN 55454. Electronic address:

Globally, the primary focus of public health attention on female sex workers (FSW) has centered around condom use promotion for HIV/STI control. Although this population also faces higher risk of unintended pregnancy, less attention is paid to their reproductive health needs. In this study we characterize contraceptive needs and patterns of use among Chinese FSW and investigate the effect of contraceptive choice on condom use practices with clients. Read More

NLRP3-mediated Inflammation in CardioOncology: Sterile yet Harmful.

Transl Res 2022 Aug 7. Epub 2022 Aug 7.

Pauley Heart Center, Department of Internal Medicine, Cardiology, Virginia Commonwealth University, Richmond, VA; Pauley Heart Center, Division of Cardiology, Department of Internal Medicine, Virginia Commonwealth University, Richmond, VA 23298-0204, USA. Electronic address:

Despite significant advances and the continuous development of novel, effective therapies to treat a variety of malignancies, cancer therapy-induced cardiotoxicity has been identified as a prominent cause of morbidity and mortality, closely competing with secondary malignancies. This unfortunate limitation has prompted the inception of the field of cardio-oncology with its purpose to provide the necessary knowledge and key information on mechanisms that support the use of the most efficacious cancer therapy with minimal or no interruption while paying close attention to preventing cardiovascular related morbidity and mortality. Several mechanisms that contribute to cancer therapy-induced cardiotoxicity have been proposed and studied. Read More

Versatilely Manipulating the Mechanical Properties of Polymer Nanocomposites by Incorporating Porous Fillers: A Molecular Dynamics Simulation Study.

Langmuir 2022 Aug 10. Epub 2022 Aug 10.

State Key Laboratory of Organic-Inorganic Composites, Beijing University of Chemical Technology, Beijing 100029, People's Republic of China.

Polymer nanocomposites (PNCs) have been attracting myriad scientific and technological attention due to their promising mechanical and functional properties. However, there remains a need for an efficient method that can further strengthen the mechanical performance of PNCs. Here, we propose a strategy to design and fabricate novel PNCs by incorporating porous fillers (PFs) such as metal-organic frameworks with ultrahigh specific surface areas and tunable nanospaces to polymer matrices via coarse-grained molecular dynamics simulations.

Learn-Explain-Reinforce: Counterfactual Reasoning and Its Guidance to Reinforce an Alzheimer's Disease Diagnosis Model.

IEEE Trans Pattern Anal Mach Intell 2022 Aug 10;PP. Epub 2022 Aug 10.

Existing studies on disease diagnostic models focus either on diagnostic model learning for performance improvement or on the visual explanation of a trained diagnostic model. We propose a novel learn-explain-reinforce (LEAR) framework that unifies diagnostic model learning, visual explanation generation (explanation unit), and trained diagnostic model reinforcement (reinforcement unit) guided by the visual explanation. For the visual explanation, we generate a counterfactual map that transforms an input sample to be identified as an intended target label. Read More

A novel attention-getting vocalization in zoo-housed western gorillas.

PLoS One 2022 10;17(8):e0271871. Epub 2022 Aug 10.

Zoo Atlanta, Atlanta, Georgia, United States of America.

As a critical aspect of language, vocal learning is extremely rare in animals, having only been described in a few distantly related species. New evidence, however, extends vocal learning/innovation to the primate order, with zoo-housed chimpanzees and orangutans producing novel vocal signals to attract the attention of familiar human caregivers. If the ability to produce novel vocalizations as a means of navigating evolutionarily novel circumstances spans the Hominidae family, then we can expect to find evidence for it in the family's third genus, Gorilla.

A recent update on new synthetic chiral compounds with antileishmanial activity.

Chirality 2022 Aug 10. Epub 2022 Aug 10.

Department of Biomolecular Science, University of Urbino Carlo Bo, Urbino, Italy.

Parasitic diseases, including malaria, leishmaniasis, and trypanosomiasis, affect billions of people and are responsible for almost 500,000 deaths/year. In particular, leishmaniasis, a neglected tropical disease, is considered a global public health problem because current drugs have several drawbacks including to toxicity, high cost, and drug resistance, which result in a lack of effective and readily available therapies. Therefore, the synthesis of new, safe, and effective molecules still requires the attention of the scientific community. Read More

Childhood Physical Health and Attention Deficit/Hyperactivity Disorder: A Systematic Review and Meta-Analysis of Modifiable Factors.

Prev Sci 2022 Aug 10. Epub 2022 Aug 10.

Gryphon Scientific, Takoma Park, MD, USA.

Although neurobiologic and genetic factors figure prominently in the development of attention deficit/hyperactivity disorder (ADHD), adverse physical health experiences and conditions encountered during childhood may also play a role. Poor health is known to impact the developing brain with potential lifelong implications for behavioral issues. In attempt to better understand the relationship between childhood physical health and the onset and presence of ADHD symptoms, we summarized international peer-reviewed articles documenting relationships between a select group of childhood diseases or health events (e.

SGLT2 Inhibitors: New Hope for the Treatment of Acute Myocardial Infarction?

Am J Cardiovasc Drugs 2022 Aug 10. Epub 2022 Aug 10.

Department of Cardiology, The First Affiliated Hospital of Nanjing Medical University, 300 Guangzhou Road, Nanjing, 210029, Jiangsu, China.

Among all of the new antidiabetic drugs, an increasing number of studies have evaluated the relationship between the sodium-glucose cotransporter 2 inhibitors (SGLT2i) and acute myocardial infarction (AMI). Since SGLT2i like empagliflozin, canagliflozin, and recently, dapagliflozin have shown impressive positive effects in patients with chronic heart failure with reduced ejection fraction (HFrEF), it has increased research interest to explore the cardiac molecular mechanisms underlying the clinical benefits and attracted more attention to the effects of SGLT2i on a series of cardiovascular events. Experimental and clinical data on SGLT2i treatment after AMI is limited. Read More

Ending the Energy-Poverty Nexus: An Ethical Imperative for Just Transitions.

Sci Eng Ethics 2022 Aug 10;28(4):36. Epub 2022 Aug 10.

School for the Future of Innovation in Society, Arizona State University, PO Box 875603, Tempe, AZ, 85287-5603, USA.

Arguments for a just transition are integral to debates about climate change and the drive to create a carbon-neutral economy. There are currently two broad approaches rooted in ethics and justice for framing just energy transitions. The first can be described as internal to the transition and emphasizes the anticipation, assessment, and redressing of harms created by the transition itself and the inclusion in transition governance of groups or communities potentially harmed by its disruptions.

Longitudinal expression profiling identifies a poor risk subset of patients with ABC-type Diffuse Large B Cell Lymphoma.

Blood Adv 2022 Aug 10. Epub 2022 Aug 10.

Barts Cancer Institute, Queen Mary University of London, London, United Kingdom.

Despite the effectiveness of immuno-chemotherapy, 40% of patients with diffuse large B-cell lymphoma (DLBCL) experience relapse or refractory disease. Longitudinal studies have previously focused on the mutational landscape of relapse but falling short of providing a consistent relapse-specific genetic signature. In our study, we have focussed attention on the changes in gene expression profile accompanying DLBCL relapse using archival paired diagnostic/relapse specimens from 38 de novo DLBCL patients.
