OBJECTIVE
Children’s hospitals are implementing interventions to connect families to community-based resources. This study describes food insecurity (FI) and food resource knowledge, need, and use among families with a hospitalized child.

METHODS
Between November 2020 and June 2022, 637 caregivers of hospitalized children in an urban 42-ZIP-code area were surveyed as part of a randomized controlled trial. The United States Department of Agriculture 18-item Household Food Security Survey was used to evaluate 12-month food security (food secure [score of 0=FS]; marginally secure [1–2=MFS]; insecure [3–18=FI]). Food resource knowledge, need, and use were described by food security status and examined using Cochran-Armitage tests. The distribution of local resources was obtained from a database and mapped by ZIP code.

RESULTS
Comparing FI (35.0%) with MFS (17.6%) and FS (47.4%) groups, the rates of resource knowledge were lower (70.2% vs 78.5%, 80.5%), and the rates of need (55.1% vs 30.6%, 14.2%) and use (55.3% vs 51.4%, 40.8%) were higher. Rates of food resource knowledge increased linearly with increasing food security (FI to MFS to FS; P = .008), whereas the rates of resource need (P &lt; .001) and use (P = .001) decreased with increasing food security. There were 311 community-based organizations across 36 ZIP codes with participants (range/ZIP code = 0–20, median = 8).

CONCLUSIONS
Half of families with a hospitalized child experienced FI or MFS. Although families exhibited high food resource knowledge, nearly half of families with FI had unmet food needs or had never used resources.
Definite, indefinite, and kind interpretations from a cross-linguistic perspective
Authors: Maleczki Márta 
Published: June 2024

AbstractThis paper argues that the indefinite, definite, and kind interpretations belonging to nouns and noun phrases are independent universal semantic features realized by different linguistic means across and within languages. The investigations presented here take the viewpoint of the speaker: first the semantic content of the three features is characterized, then the linguistic expressions these interpretations belong to and arise from are examined. Cross-linguistic data support the conclusions that none of these features is derived from the other(s), their primary source is the intrasentential context, and they express “instructions” to the hearer to find more or less identifiable or more or less representative referents that pertain to the denotation of the noun (phrase).
АВТОРСКИЕ ПРАВА И ИНДЕКСЫ ЦИТИРОВАНИЯ НА НАУЧНЫЕ ПУБЛИКАЦИИ УЧЕНЫХ И СПЕЦИАЛИСТОВ
Authors: ОМОРОВ Роман Оморович 
Published: June 2024

Научные публикации как произведения науки являются одними из значимых объектов авторского права. Как известно, для оценки научной продуктивности ученых и специалистов в наукометрии применяют различные показатели, наиболее распространенным из которых является индекс Хирша, или h-индекс. Индекс Хирша вычисляется по количеству цитирований трудов исследователя, включенных в определенную базу данных. Для стран СНГ важной базой научных и учебных публикаций является база данных Российского индекса научного цитирования (РИНЦ). В Международном плане широкое распространение получили базы данных Scopus, Web of Sciences. Одна из проблем использования индекса Хирша это соответствие оценок нормам авторского права. Индекс Хирша показывает сравнительную эффективность труда ученого или коллектива ученых. Но, как нетрудно видеть, по показателям подсчета индекса Хирша по базам данных РИНЦ для отдельных ученых не учитываются их вклад и участие в коллективных публикациях и их цитированиях. В случае когда публикации осуществляют группы, коллективы ученых, все участвующие в издании совместного научного труда ученые и исследователи обладают статусами соавторов этой публикации. Отношения между соавторами определяются на основе соглашения, при отсутствии которого авторское право на публикацию осуществляется всеми соавторами совместно, а вознаграждение распределяется между ними поровну. Предложено для оценки индивидуального показателя цитирования публикаций ученых ввести модифицированный индекс Хирша, называемый индекс Хирша «плюс», или h+, который вычисляется на основе деления обычного числа цитирований конкретной публикации на число соавторов цитируемой публикации, что не вызовет трудностей при вычислениях индексов h+ с использованием алгоритма определения собственно индекса Хирша. Такой показатель учитывает интересы соавторов с точки зрения авторских прав и более точно оценивает эффективность труда конкретного ученого при сравнительных оценках их труда. Также для сравнительной оценки индивидуальных индексов цитирования ученых и специалистов предлагается ввести авторский коэффициент усреднения индексов kc, равный кубическому корню от общего количества соавторов, на который делится соответствующий индекс Хирша или иной индекс цитирования конкретного автора.

Background. One of the most common malignant tumors is colorectal cancer. Colorectal cancer is characterized by frequent metastasis to the liver, lungs, peritoneum and distant lymph nodes, and therefore its treatment is complicated. Therefore, it is urgent to search for new drugs and treatment methods based on the molecular mechanisms underlying metastatic colorectal cancer.Aim. To study the mechanism of action of cytostatic drug regimens with the addition of lysine acridone acetate to increase the effectiveness of anti-oncogenic chemotherapy in metastatic colorectal cancer.Materials and methods. We used mice of Nude line at the age of 4 weeks with inoculated tumor cells of SW837 line, which were administered chemotherapy drugs (FOLFOXIRI и FOLFOX6). On biopsy samples of liver metastases, the apoptosis level (TUNEL) and the expression of proteins CD95, p53, BCL2, histone H3, Ki-67 (immunohistochemistry) were assessed.Results. An activating effect of the studied therapeutic regimens was revealed, which was more active with the addition of lysine acridone acetate, on the development of p53-dependent apoptosis and the expression of H3K27me3 (a marker of treatment effectiveness and tumor progression) in colorectal cancer metastases in the liver of experimental mice. At the same time, the level of cancer cell proliferation (Ki-67 expression) decreased.Conclusion. Increased apoptosis in mouse liver metastases, as well as a decrease in cancer cell proliferation when using these drug regimens should be regarded as a positive therapeutic effect. A p53-dependent mechanism of apoptosis activation under the influence of appropriate treatment regimens has been revealed. Lysine acridone acetate may be preferable for clinical study.

Relevance. To date, all pathognomonic clinical and radiological signs have not been identified for any disease manifested in the form of cavities in the lung, which leads to diagnostic errors, the frequency of which varies from 19 to 93.7% in various pathological processes in the lungs. The clinical course of most forms of cavities can often be complicated by the development of respiratory failure and/or pulmonary hemoptysis/bleeding.Aim: to demonstrate the result of surgical treatment of a patient with a cavity formation of an operated lung complicated by recurrent pulmonary hemoptysis. Object and methods. A clinical case of successful application of extrapleural pneumolysis with the installation of a silicone implant from the operated lung as a method of eliminating sanitized cavities is described.Clinical case description. Patient M., 54 years old, long-term follow-up for rheumatoid arthritis, receiving courses of immunosuppressive therapy, noted the appearance of cough, a single episode of hemoptysis. Pulmonary tuberculosis was excluded based on the clinical and radiological picture. Due to the recurrence of hemoptysis, an upper lobectomy was performed on the left. In the histological examination of the surgical material: the morphological picture is characteristic of bronchiectasis of the lung with the development of nonspecific purulent granulomatous inflammation. Due to repeated episodes of hemoptysis, extrapleural pneumolysis was performed with the installation of a silicone implant, after which the episodes were not repeated.Conclusion. The EPSI collapsosurgical method made it possible to preserve the patient's functional reserves as much as possible and compress the lung cavity formation, which confirms its high effectiveness.

Relevance. The study of pigmented melanoma of the skin is an urgent problem today, because this pathology has an aggressive course, frequent localization on the skin, rare occurrence – no more than 2-8% among other malignant neoplasms of the skin, while it is difficult to diagnose clinically, pathohistologically.The purpose of the study: to study the clinical, dermatoscopic and pathomorphological diagnosis of pigmented and pigmented melanoma of the skin. As tasks, the possibilities of diagnosing pigmented and pigmentless melanoma of the skin at the stage of consultation, as well as the features of the use of light microscopy and immunohistochemical examination by pathologists were studied.Material and technical base: Delta Heine 20 dermatoscope, Carl Zeiss Axio Scope A2 light microscope, evaluation of results according to clinical recommendations. As a result of the study, it was revealed that the diagnosis of pigmented, unlike pigmented, melanoma of the skin is difficult due to the lack of characteristic signs. It was concluded that it is advisable to use digital dermatoscopy at the clinical stage; an immunohistochemical examination should be used by a pathologist; if there is doubt about the goodness of the process, an incisional biopsy of the neoplasm with a pathohistological examination is required.
Antegrade choledochoscopy in laparoscopic cholecystectomy is a method of diagnosis and treatment of papillostenosis

Published: June 2024

In the last 30-40 years, there has been a trend in the incidence of cholelithiasis, which, in turn, is often complicated by the development of papillostenosis of various degrees requiring surgical correction. Currently, it is widely used in the diagnosis and treatment of papillostenosis: retrograde choledochopancreatography and endoscopic papillosphincterotomy, but these types of surgical correction of the pathology of large duodenal papilla have a number of disadvantages. In this connection, antegrade choledochoscopy with subsequent augmentation is an option for the diagnosis and correction of papillostenosis narrowing.Aim: of the study is to study domestic and foreign literature on methods of diagnosis and treatment of papillostenosis. To conduct a comparative analysis of the instrumental methods presented in practice, to evaluate the effectiveness of endoscopic antegrade choledochoscopy in papillostenosis.Materials and methods. 31 case histories of a patient who was hospitalized in the Department of Surgery of the Hospital No. 18 from 2013 to 2022 with papilla stenosis complicated by mechanical jaundice, who underwent followed by papillaa ugmentation, were analyzed. A narrowing of the lumen of the papilla of less than 2 mm was considered an indication for antegrade choledochoscopy with buging. The postoperative period in 100 % of patients proceeded without peculiarities. The number of bed-days of hospital stay is 4-6 days, discharged with improvement.Of 100 % of patients - 3.2 % (1 patient) – had a history of papilla restenosis after undergoing laparoscopic cholecystectomy, antegrade choledoscopy and augmentation (4.5 years after the first intervention), he underwent retrograde choledochopancreatography and endoscopic papillosphincterotomy.Conclusion. As presented for 10 years of experience in the use of antegrade choledochoscopy with the bougie of papilla in laparoscopic cholecystectomy, this technique for the diagnosis and treatment of papillostenosis has a large 5-year effectiveness (96.8 %), sensitivity, both due to the optical component of diagnosis and due to the objective component – bougie. In this connection, this method can be used in the practice of a surgeon.

Relevance. Modern surgery is characterized by the use of various technical means to perform classical surgical techniques - separation and connection of tissues, hemostasis. The study of the applicability of new surgical devices and the search for technological techniques are an important task.The aim of the study: to evaluate the capabilities of the developed device based on microwave energy for hemostatic coagula­tion of resection surfaces of parenchymal organs.Materials and methods. The method is based on the principle of converting microwave energy into heat when it is absorbed in biological tissue. The choice of the microwave range is due to the higher efficiency of power supply to the heat­ing area. Based on the prototype of a medical microwave complex developed in 2011 for thermal effects on biological tissues (RF Patent 2481080. 2011), a prototype of a microwave coagulator for working with parenchymal organs was created. The device was tested on the paren­chymal organs of large laboratory animals under conditions of preserved and switched off blood flow in various energy supply modes. Tissue samples from coagulated lesions were studied histologically.Results. At the site of exposure of the applicator-coagulator to the parenchymal organ, a zone of coagulation changes appears. A clear dependence of the size of coagulation necrosis on the time and power of exposure was noted. When the blood flow is turned off, the necessary stable hemostasis is achieved by shorter exposure time of the coagulator antenna on the surface of the organ.Conclusions. The most effective and reliable hemostasis is achieved on the liver parenchyma. The use of temporary vascular isolation, especially on the kidneys and spleen, involves a single use of microwave energy to stop bleeding. By changing the power and duration of exposure, it is possible to dose the thermal load on biological tissue with great precision. This adjustment allows you to select the operating mode for each specific case. The obtained results of the experiment of the described system during surgery for the purpose of hemostasis in parenchymal bleeding.

Background. Chronic liver disease is one of the most common diseases. In many countries, liver disease is among the top five causes of death. The liver is one of the main organs responsible for basic metabolic functions, protein and hormone synthesis, detoxification and waste elimination. In chronic liver disease, there is a continuous process of inflammation, destruction and regeneration, ultimately leading to severe dysfunction, causing the development of fibrosis and cirrhosis. The main task of the radiation diagnosis of chronic liver disease is the development and introduction into clinical practice of new noninvasive biomarkers for a comprehensive assessment of the structure of the liver parenchyma in order to choose further treatment tactics.Aim a comprehensive analysis of the modern possibilities of radiation imaging methods in the diagnosis of chronic liver disease.Materials and methods. The analysis of 107 modern publications of domestic and foreign literature devoted to the diagnosis of chronic liver disease of various etiologies was carried out.Conclusion. the review reflects the most common modern and promising methods of radiodiagnosis for chronic liver disease, which in most cases make it possible to avoid invasive interventions in the process of establishing a diagnosis and monitoring the response to treatment

Background. Multiple sclerosis (MS) is a chronic autoimmune demyelinating disease, which is characterized by the inevitable disability of patients in the long term, which determines the relevance of this problem. Currently, active improvements are being made in the methods of diagnosing multiple sclerosis, which include the use of the central vein sign in magnetic resonance imaging (MRI) as a neuroimaging biomarker of MS with high sensitivity and specificity.Aim of study. Determination of the possibility of assessing the central vein sign (CVS) according to MRI data as a potential diagnostic biomarker of MS.Object and methods. An open single-center prospective study of brain MR data was conducted in 55 patients with a verified diagnosis of MS (EDSS 1.0-6.5) aged 19 to 72 years. MR-images were obtained on a tomograph with a magnetic field induction force of 3.0 T. Patients underwent MRI of the brain according to the standard protocol: T2-VI, FLAIR, T1-VI (before and after administration of contrast agent), SWI. A comprehensive statistical analysis and evaluation of the obtained MRI data was performed using the Statistica 12 program.Result. During the evaluation of MR-tomograms, all patients with a verified diagnosis in the foci of MS were found to have CVS. In 14.5 % of patients, CVS was detected in 10-30 % of foci, in 61.8 % of patients in 30-60 %, in 23.6 % of patients, from 60 to 95 % was detected. Accordingly, 52.7 % of patients overcame the threshold value of 45 % required for the differential diagnosis of MS from other conditions.Conclusion. The use of CVS in MRI helps to solve the problem of differential diagnosis of MS from other demyelinating diseases when using its threshold criterion – the percentage of foci containing central veins.

Published: June 2024

» Pediatric thoracolumbar trauma, though rare, is an important cause of morbidity and mortality and necessitates early, accurate diagnosis and management.» Obtaining a detailed history and physical examination in the pediatric population can be difficult. Therefore, the threshold for advanced imaging, such as magnetic resonance imaging, is low and should be performed in patients with head injuries, altered mental status, inability to cooperate with examination, and fractures involving more than 1 column of the spine.» The classification of pediatric thoracolumbar trauma is based primarily on adult studies and there is little high-level evidence examining validity and accuracy in pediatric populations.» Injury pattern and neurologic status of the patient are the most important factors when determining whether to proceed with operative management.
Modest geoengineering side effects predicted by an emulator

Abstract

It is common to speak about side effects of solar radiation management geoengineering considering that the forcing involved is different in nature from the anthropogenic greenhouse forcing. However, we argue that even if side effects are identified in terms of uncontrolled changes of climatic variables, they should scale with the geoengineering forcing magnitude. This would dictate a definition of side effects that takes a reference scenario where the same target is achieved, e.g. limiting the global mean surface temperature to an agreed maximum, without deploying geoengineering, but, say, by CO2 abatement only. We use a response theory based emulator, derived from new simulation output for the Max Planck Institute’s Earth system model, MPI-ESM, as well as the cGENIE carbon cycle model, in order to evaluate regional side effects regarding annual mean surface temperature and total precipitation in this sense. We find that the respective spatial patterns of the side effects bear the features as those known from the G2-type “cancellation” experiments of the Geo-MIP protocol – more so for temperature than precipitation. The former is governed by the effect of polar amplification, for which we provide now a succinct mathematical model, both for the greenhouse and geoengineering forcing, and explain the G2-type temperature pattern.
