OBJECTIVES

To examine how timing of the first outpatient mental health (MH) visit after a pediatric firearm injury varies by sociodemographic and clinical characteristics.

METHODS

We retrospectively studied children aged 5 to 17 years with a nonfatal firearm injury from 2010 to 2018 using the IBM Watson MarketScan Medicaid database. Logistic regression estimated the odds of MH service use in the 6 months after injury, adjusted for sociodemographic and clinical characteristics. Cox proportional hazard models, stratified by previous MH service use, evaluated variation in timing of the first outpatient MH visit by sociodemographic and clinical characteristics.

RESULTS

After a firearm injury, 958 of 2613 (36.7%) children used MH services within 6 months; of these, 378 of 958 (39.5%) had no previous MH service use. The adjusted odds of MH service use after injury were higher among children with previous MH service use (adjusted odds ratio, 10.41; 95% confidence interval [CI], 8.45–12.82) and among non-Hispanic white compared with non-Hispanic Black children (adjusted odds ratio, 1.29; 95% CI, 1.02–1.63). The first outpatient MH visit after injury occurred sooner among children with previous MH service use (adjusted hazard ratio, 6.32; 95% CI, 5.45–7.32). For children without previous MH service use, the first MH outpatient visit occurred sooner among children with an MH diagnosis made during the injury encounter (adjusted hazard ratio, 2.72; 95% CI, 2.04–3.65).

CONCLUSIONS

More than 3 in 5 children do not receive MH services after firearm injury. Previous engagement with MH services and new detection of MH diagnoses during firearm injury encounters may facilitate timelier connection to MH services after injury.

Biological differences associated with sexual dimorphism have an impact on many aspects of health, including disease susceptibility, course and prognosis. Significant differences in the incidence and severity of neurological diseases, especially those of autoimmune origin, were found between women and men. Although the reasons for the observed discrepancies are complex, research indicates the key role of sex hormones, which are known to be responsible for the differences in body structure, genitals and sexual behaviour in women and men. Recent data have drawn attention to their impact on the function of the immune and nervous systems, the brain and the spinal cord in particular. Multiple sclerosis is a chronic disease of the central nervous system that affects more than twice as many women as men. The etiopathogenesis of the disease is complex, with genetic and environmental factors playing an important role. There are three main components in the pathology of multiple sclerosis: inflammation, demyelination and neurodegeneration. Studies conducted so far have shown a significant influence of sex hormones, both male and female, on each of these elements. It has been shown in both clinical and experimental studies that sex hormones have not only a strong immunomodulatory, but also neuroprotective and neuroregenerative effect. Recent research on the role of sex hormones in multiple sclerosis has led to a better understanding of the mechanisms underlying the development of this disorder. They also gave hope for the introduction of sex hormones as diagnostic tools, i.e. biomarkers of progression and response to treatment, but above all, as breakthrough therapies.

Stroke is the leading cause of acquired disability in adults. Although all age groups may be affected, the risk of fatal outcome increases with age. Diagnostic imaging, including computed tomography and magnetic resonance imaging, is used in order to promptly initiate effective treatment. Imaging modalities make it possible to determine the type of stroke as well as the location and extent of damage. They are also used for treatment monitoring. It is essential to make an early diagnosis, identify the type of stroke and implement appropriate management. After the introduction of modern treatment modalities, such as thrombolytic therapy, time windows, i.e. periods of time during which a given intervention may bring benefits to the patient, were established for ischaemic stroke. The performance and life quality in a person after a stroke depends on the duration of neural ischaemia. The consequences of stroke also depend on the baseline condition of the patient. The incidence of stroke in the general population is shaped by risk factors that are often cumulative in nature. Scientific reports most often point to age, race, sex, blood glucose and diabetes, obesity, smoking and atherosclerosis. Ischaemic stroke is frequently caused by arterial stenosis or obstruction. According to one hypothesis, the activity of immune cells, including monocytes and basophils, in atherosclerosis leads to inflammation and formation of atherosclerotic plaques. As a result, wall thickening, atherosclerotic plaque rupture, regenerative responses and stenosis occur. The aim of the paper is to summarise the relationships between vasculitis, bacterial and viral infections or autoimmune disorders and stroke, in the etiopathogenesis of which, according to current research, they are involved. The paper also shows the importance of diagnostic imaging and attempts to explain the relationship between changes in computed tomography and magnetic resonance imaging and risk factors for stroke.

Natalizumab is a recombinant humanized monoclonal antibody, that binds to the integrin α4-subunit, inhibits the adhesion of lymphocytes to vascular endothelial cells and their infiltration into the central nervous system. In April 2021, a subcutaneous form of natalizumab, which until recently could only be administered intravenously, was registered in the European Union. Due to a shorter and simpler administration regimen, greater patient comfort and reduced healthcare costs, subcutaneous natalizumab is a highly convenient form of therapy, both for patients and healthcare professionals. The subcutaneous form is also an alternative for patients with difficult venous access. In this paper, we present four patients with relapsing-remitting multiple sclerosis of different duration, treated with natalizumab. The presented clinical cases are a summary of the first Polish experiences with subcutaneous natalizumab.

Published: June 2023

Multiple sclerosis is a common autoimmune and neurodegenerative disease of the central nervous system in women of reproductive age. The average age of onset is around 30 years. A few decades ago, women with multiple sclerosis were often advised to avoid pregnancy, but this has changed. Discontinuation of treatment due to pregnancy is often associated with clinical and radiological progression of multiple sclerosis. According to current expert recommendations, if a patient presents with highly active multiple sclerosis, continuation of treatment with natalizumab may be considered even during pregnancy. Treatment can be continued until 30–34 weeks of gestation and resumed as soon as possible after delivery, 2–3 weeks after childbirth or 8–12 weeks after the last infusion, to reduce the risk of disease reactivation. The dosing interval should be extended to 6 weeks. Cases of mild to moderate transient thrombocytopenia and anaemia have been reported in infants born to mothers exposed to natalizumab in the third trimester of pregnancy. Haematological abnormalities have been shown to normalise within 4 months after birth in most infants. This article presents the case of a patient with multiple sclerosis who has been successfully treated with natalizumab for several years and decided to continue her treatment during pregnancy, with an emphasis on the impact of the drug on the newborn’s laboratory parameters.
Life under Roman rule – In parts of present-day Hungary
Authors: Erdmann Elisabeth
Published: June 2023

The Roman Empire covered a large area, including parts of present-day Hungary. There are many still visible remains in the landscape or in museums. In addition to written sources, there are monuments ranging from objects to architecture, pictures and sculptures. This makes it possible to question and compare the significance of the individual sources. In addition, there is the interdisciplinarity, for many insights are only gained by applying scientific but also linguistic and other reference disciplines. Many things from Roman antiquity seem familiar to us at first glance, especially when it comes to concepts such as the state and the republic, but also to things of everyday life. But on closer inspection, the familiarity disappears when it comes to social rules, behaviour and norms. Therefore, there are lots of opportunities to interest and motivate pupils of different ages to learn about history. Selected examples will show how attractive the Roman period in Hungary can be for pupils.

Published: June 2023

Hyphessobrycon langeanii was originally described as endemic to the upper Araguaia river basin, Brazil. However, our analysis of several Hyphessobrycon specimens collected in the Correntes river basin and another tributary of the Itiquira River in Mato Grosso state (both belonging to the Paraguay river basin) reveals the first verified record of H. langeanii from this basin and from the states of Mato Grosso do Sul and Mato Grosso. The objective of this study is to provide a novel record of H. langeanii from the basin of the Paraguay River and from the state of Mato Grosso do Sul. We compare the newly discovered populations with the populations in the Araguaia river basin, and we also provide a brief discussion on the biogeography of this species.
Progression of the dealloying front in bilayer Cu–Al and Cu–Zn nanoporous foams
Authors: Hemmendinger Karina D. , Hodge Andrea M.
Published: June 2023

The role of interfaces and the controlling synthesis parameters of graded dealloyed nanoporous metallic materials are investigated, focusing on the dealloying front progression in complex precursor materials with multiple alloy compositions. Specifically, the effects of relative density and chemical potential on the dealloying front in sputtered bilayer copper alloy films are explored with two case studies: Cu–Al/Cu–Al and Cu–Al/Cu–Zn. Cross-sectional scanning electron (SEM) micrographs and energy-dispersive X-ray spectroscopy mapping trace the dealloying front across three time intervals, while top-surface and cross-sectional SEM probes the final dealloyed foam morphology. Final ligament sizes were found to be independent of the synthesis parameters (21–28 nm), due to a combination of fast reaction times and phosphate-inhibited surface diffusion of Cu atoms. The chemical potential gradient yielded faster reaction times, whereas slower reaction times and a higher at.% of Cu in the top layer of precursor material produced a more uniform morphology.

Published: June 2023

Phytoestrogens, structurally and functionally of mammalian estrogens, are phenolic soybean-derived compounds. The aglycone phytoestrogens in soy germ including daidzein, genistein, and glycitein have been known for higher biological activity than the other derivative forms. The objective of this study was to assess the potential for pure β-glucosidase to hydrolyze the glucoside isoflavones in phytoestrogens extract from the soy germ to enrich the aglycones content of the extract. The optimum condition for the enrichment of aglycones from soy germ evaporated extract is β-glucosidase at 4 units/g of defatted soy germ flour, and an incubation time of 5.5 hours. Under this condition, the hydrolysis of β-glycosides, malonyl glycosides, and acetyl glycosides, were more than 90%, 60%, and 60%, respectively. The isoflavone aglycones content was 31.36 ± 0.06 µmol/g (14.97 ± 0.03 µmol/g daidzein, 7.58 ± 0.05 µmol glycitein, 8.81 ± 0.02 µmol/g genistein) was 5 fold more than that of defatted soy germ flour.

Authors: Rybkin V. V. , Arbuzov M. A.
Published: June 2023

Nowadays the maintenance of long welded rails track is an urgent problem of railway industry. The inexact diagnostic method of the stressed state of long welded rails is used now on railways of Ukraine. This method does not give a direct and true picture of distribution and mode of the stress. Therefore there is a necessity of application of a new diagnostic method, which determines not only temperature stress and stress from longitudinal moving, but also initial and residual, i.e. total longitudinal stress. Taking into account that the rail is made of ferromagnetic material, the phenomenon of magnetic elasticity is used in measurement of mechanical stress. The device for the diagnostic of total mechanical longitudinal stress of static character in a rail is constructed, based on this phenomenon. The technical result of using the new method is an increase in accuracy, speed, convenience and reliability of mechanical stress measurements.
