Design of biodegradable cellulose filtration material with high efficiency and breathability.

Using respiratory protective equipment is one of the relevant preventive measures for infectious diseases, including COVID-19, and for various occupational respiratory hazards. Because experienced discomfort may result in a decrease in the utilization of respirators, it is important to enhance the material properties to resolve suboptimal usage. We combined several technologies to produce a filtration material that met requirements set by a cross-disciplinary interview study on the usability of protective equipment.

Cumulative risk factors for injuries and poisoning requiring hospital care in youth with prenatal substance exposure: A longitudinal controlled cohort study.

To investigate whether the youth with prenatal substance exposure (PSE) (aged 15-24 years,  = 615) had been in hospital care more often due to injuries and poisoning in comparison with unexposed matched controls ( = 1787). Data from medical records (exposure) and national health and social welfare registers (outcome and confounders) were combined and youths were monitored from birth until either outpatient or inpatient hospital care for injury or poisoning, death or the end of the study period (December 2016). Cox regression models were used in the analyses accounting for associated child and maternal risk factors.

Image-based and machine learning-guided multiplexed serology test for SARS-CoV-2.

We present a miniaturized immunofluorescence assay (mini-IFA) for measuring antibody response in patient blood samples. The method utilizes machine learning-guided image analysis and enables simultaneous measurement of immunoglobulin M (IgM), IgA, and IgG responses against different viral antigens in an automated and high-throughput manner. The assay relies on antigens expressed through transfection, enabling use at a low biosafety level and fast adaptation to emerging pathogens.

Adverse childhood experiences and neurodevelopmental disorders among youth with and without prenatal substance exposure: A longitudinal matched register-based cohort study.

Previous research has shown an association between adverse childhood experiences (ACEs) and secondary mental health problems in youth with prenatal substance exposure (PSE), but the association between ACEs and neurodevelopmental disorders is less clear. This longitudinal register-based cohort study investigated relationships between health at birth, ACEs (out-of-home care (OHC) and maternal adversities), and neurodevelopmental disorders among youth with PSE (alcohol/drugs,  = 615) and matched unexposed controls ( = 1787). Hospital medical records and register data were merged and analysed using Cox regression models.

Mood and neurotic disorders among youth with prenatal substance exposure: A longitudinal register-based cohort study.

Background: Prenatal substance exposure is associated with mood and neurotic disorders but this association is complex and understudied. This study investigated the recorded use of specialised healthcare services for mood and neurotic disorders among youth with prenatal substance exposure in comparison with an unexposed matched cohort. Furthermore, the influence of adverse maternal characteristics and out-of-home care (OHC) is investigated.
