Introduction. Pension systems are a key element of social protection for the elderly. They are designed to provide senior citizens with stable income not from work. However, pension systems currently being developed in Europe are increasingly exposing the working-age population to the risk of poverty in old age. The European pension paradigm strives for an adequate level of pension payments and builds financial protection against poverty, while the future evolution of wages and prices remains unknown for Europe as a whole. Methods. Scientific research is based on general and special methods of scientific cognition. In the process of forming the concept of the scientific article, modern scientific methods of studying economic and social phenomena were used, including methods of system-structural, functional, factorial and comparative analysis, as well as categorical, logical and structural analysis and synthesis, detailing and generalization, grouping and comparison, identification of cause-and-effect relationships. The authors proceed from an understanding of the scientific hypothesis of reforming the pension system, which ensures long-term investment by the working-age population with income in the future. The empirical base of the study was made up of current data from cross-country comparative studies of Europe in terms of typology of state pension systems. Results. Based on the functional method of cognition, the authors of the scientific article systematize the main types of state pension systems of the European Union, representing the complex content of the indicator value of pension payments. It is noted that in the context of reforming the pension systems of the European Union countries, the reorganization of the functional and ideological components of pension provision, aimed at protecting consumers of pension savings, makes it possible to increase the socio-economic standard of living. Although EU pension systems differ in many respects, they all have one common problem - finding ways to maintain the financial sustainability of the budgetary system while paying pensions in the long term against the backdrop of an aging population and the problem of increasing the ratio of pensioners to the working-age population.

Abstract Premise Poikilohydric plants respond to hydration by undergoing dry–wet–dry cycles. Carbon balance represents the net gain or loss of carbon from each cycle. Here we present the first standard protocol for measuring carbon balance, including a custom‐modified chamber system for infrared gas analysis, 12‐h continuous monitoring, resolution of plant–substrate relationships, and in‐chamber specimen hydration. Methods and Results We applied the carbon balance technique to capture responses to water stress in populations of the moss Syntrichia caninervis, comparing 19 associated physiological variables. Carbon balance was negative in desiccation‐acclimated (field‐collected) mosses, which exhibited large respiratory losses. Contrastingly, carbon balance was positive in hydration‐acclimated (lab‐cultivated) mosses, which began exhibiting net carbon uptake

Quantum processors based on linear arrays of trapped ions have achieved exceptional performance, but scaling to large qubit numbers requires realizing two-dimensional ion arrays as envisioned in the quantum charge-coupled device (QCCD) architecture. Here, we present a scalable method for the control of ion crystals in a grid-based surface-electrode Paul trap and characterize it in the context of transport operations that sort and reorder multispecies crystals. By combining cowiring of control electrodes at translationally symmetric locations in each grid site with the sitewise ability to exchange the voltages applied to two special electrodes gated by a binary input, site-dependent operations can be achieved using only a fixed number of analog voltage signals and a single digital input per site. In two separate experimental systems containing nominally identical grid traps, one using ^{171}Yb^{+}-^{138}Ba^{+} crystals and the other ^{137}Ba^{+}-^{88}Sr^{+}, we demonstrate this method by characterizing the conditional intrasite crystal reorder and the conditional exchange of ions between adjacent sites on the grid. Averaged across a multisite region of interest, we measure subquanta motional excitation in the axial in-phase and out-of-phase modes of the crystals following these operations at exchange rates of 2.5 kHz. In this initial demonstration, the logic controlling the voltage exchange occurs in software, but the applied signals mimic a proposed hardware implementation using crossover switches. These techniques can be further extended to implement other conditional operations in the QCCD architecture such as gates, initialization, and measurement.

Introduction. Secreted metabolites with enzymatic or toxic properties are important for effecting of Candida spp pathogenicity. The most clinically significant species is C. albicans. However, invasive infections associated with C. auris have a great significance. The aim of the investigation is comparison the some of enzymatic properties and biocidal activity of C. auris with those of C. albicans. Materials and methods. C. albicans and C. auris strains were used in the study. Growth of micromycetes was detected on nutrient agar, Sabouraud agar or blood agar (with hemolysis presence). The Candida spp. proteinase activity was determined on Difco agar with 2% casein and by cleavage of IgG molecules. Candida lipase activity was assessed on the agar with Tween-20. The viability of buccal epithelial cells after exposure (1 4 h) with candida metabolites was estimated by trypan blue assay. Statistical analysis was performed using RStudio software. Results. The best growth of C. albicans was observed on Sabouraud agar, and C. auris on blood agar. Only C. auris had hemolytic and lipase activity. Protease activity of some C. auris strains was noted. They were able to cleave casein and damage IgG molecules. The metabolites of some Candida strains decreased the viability of epithelial cells while the reduction was more pronounced in the experiments with C. auris (р 0.05). Conclusion. The most suitable medium for C. auris culturing was blood agar. Proteolytic, antiglobulin, hemolytic and lipase activities were observed only for C. auris. C. auris demonstrated more invasive capacity compared to C. albicans. The observed micromycete biocidal activity against buccal epithelial cells was strain-dependent.

Abstract Background Langerhans cell histiocytosis (LCH) is a rare disorder in which Langerhans cells (LC) accumulate in the skin or other organs and cause tumor formation or organ damage. Cutaneous lesions can vary widely and do not predict extent of systemic disease or prognosis. Case We present a premature infant with skin findings, multisystem involvement, and immunohistochemical markers consistent with multisystem LCH. Conclusion Limited data from preterm neonates with LCH suggest that prognosis is particularly poor, with even limited cutaneous disease often rapidly progressing to become fatal, although diagnosis is not always prompt. Early diagnosis and treatment may affect prognosis.

Objectives: The American Academy of Pediatrics recommends discussing climate change with parents, particularly at well-child visits; however, parental opinions about receiving climate change information at their child's checkup are largely unknown. This exploratory study examines: (1) parents’ perspectives on frequency of climate change discussions during well-child visits and if climate change should be incorporated into well-child visits; and (2) associations between parents’ perspectives about climate change and if climate change should be incorporated into well-child visits. Methods: We conducted cross-sectional surveys with parents of children 0–17; parents were recruited from the waiting rooms of two clinics and an online recruitment repository. The survey included investigator-developed questions about guidance around climate change during well-child visits and questions from the Climate Change in the American Mind survey. Descriptive statistics were used to examine frequencies, means, and standard deviations. Logistic regression was used to examine associations between perspectives about climate change and how climate change should be incorporated into well-child visits. Results: A total of 371 parents (71% of those approached) completed the survey. Four percent of parents reported that global warming was discussed during their child's well visits over the past year. Eighty percent strongly agreed or agreed that the impact of global warming on their child's health should be discussed during their well visits. Fewer thought preparing for global warming (57%), reducing global warming (55%), or talking to decision makers about global warming (38%) should be covered. There were significant positive associations between parents’ perceptions about global warming and their agreement that global warming should be incorporated into well-child visits. Conclusion: Results of this exploratory study suggest parental interest in incorporating climate change into well-child visits. Further research should be conducted with a larger, more diverse population, consider perspectives of providers and children, and develop best practices for inclusion of climate change into the pediatric medical home.

Because herbivory is a critical component of resilient reefs, there is a need to investigate the dynamics of herbivorous fish assemblages over various spatiotemporal scales. During the period of 2011–2019, 483 belt transect surveys were conducted across 26 sites around New Providence to assess the status of parrotfish populations across different reefs. Non-metric multidimensional scaling revealed two distinct parrotfish assemblages around New Providence temporally, differing between 2019 and earlier surveys, and spatially between fore and patch reef zones. Temporal analysis showed a significant decrease (59%) in parrotfish densities across reef sites and significant changes in mean density over time for three species Scarus iseri, Sparisoma aurofrenatum and Sp. atomarium. Changes in the size frequency distribution of parrotfish—particularly reductions in individuals ≥31 cm in size and the complete loss of fish >40 cm across all sites were found. Interactions between reef zone and size class were significant with the greater frequencies of larger individuals (≥21 cm) driving patterns (positive associations) on forereefs. These patterns also appear to be partly driven by variability in the abundance and size composition of Sparisoma viride, which is one of the species primarily targeted by Bahamian fishers, as well as one of the most common parrotfish across reef zones.

Providing patients, parents, and families high-quality healthcare in the language of their choice is a fundamental component of patient-centered care in pediatric settings. However, language needs may be complex and dynamic, creating clinical and ethical challenges in cases of provider?parent discordance regarding the need for an interpreter. In this perspectives article, we use a clinical encounter as a foundation to discuss the intricacies of addressing language needs in pediatrics. We also describe the urgent need for further innovation and improvement in linguistic supports available to diverse patients and families.

Despite the growing popularity of heated tobacco products, there are few comprehensive studies on their environmental aerosols. Therefore, the impact of the Tobacco Heating System 2.2 (THS 2.2) on indoor air quality was evaluated on the basis of a comprehensive list of 31 airborne constituents along with targeted screening of the gas–vapor and particulate phases of the environmental aerosol. The assessments were conducted at three ventilation rates. Indoor use of THS 2.2 increased the levels of nicotine, acetaldehyde, glycerin, and (if mentholated products were used) menthol relative to background levels, with a corresponding increase in total volatile organic compounds (TVOC) values. Moreover, a temporary increase in ultrafine particles was observed when two or more tobacco sticks were used simultaneously or with a short time lapse between usages, but the concentrations returned to close to background levels almost immediately. This is because THS 2.2 generates an aerosol of liquid droplets, which evaporate quickly. Nicotine, acetaldehyde, glycerin, and TVOC levels were measured in the low μg/m3 range and were below the existing guideline limits. A comparison of airborne constituent levels during indoor THS 2.2 use with emissions from combustion products and common everyday activities revealed a substantially lower impact of THS 2.2 on the indoor environment.

Chromosome segregation—the partitioning of genetic material into two daughter cells—is one of the most crucial processes in cell division. In all Eukaryotes, chromosome segregation is driven by the spindle, a microtubule-based, self-organizing subcellular structure. Extensive research performed over the past 150 years has identified numerous commonalities and contrasts between spindles in different systems. In this review, we use simple coarse-grained models to organize and integrate previous studies of chromosome segregation. We discuss sites of force generation in spindles and fundamental mechanical principles that any understanding of chromosome segregation must be based upon. We argue that conserved sites of force generation may interact differently in different spindles, leading to distinct mechanical mechanisms of chromosome segregation. We suggest experiments to determine which mechanical mechanism is operative in a particular spindle under study. Finally, we propose that combining biophysical experiments, coarse-grained theories, and evolutionary genetics will be a productive approach to enhance our understanding of chromosome segregation in the future.

The “chlorination/fluorination” technique for aliphatic trifluoromethyl ether synthesis was investigated and a range of products with various functional groups was prepared. The results were compared with oxidative desulfurization-fluorination of xanthates with the same structure.

Introduction: Economic abuse is one form of intimate partner violence (IPV) intended to control a survivor's ability to make, save, or spend money to gain power over them. Perinatal people may be more vulnerable to economic abuse due to changes in employment and finances. This study's aims were to explore how economic abuse manifests among pregnant and parenting survivors and how best to support pregnant and parenting survivors of economic abuse. Methods: We conducted virtual semistructured interviews with IPV survivors and IPV advocates. Participants were recruited through an online recruitment registry, national IPV organizations, and local domestic violence agencies. Interview audiorecordings were transcribed. We used a deductive–inductive thematic analysis approach. Two research team members individually coded each transcript and met to resolve discrepancies in coding. Results: We completed interviews with 18 advocates and 20 survivors. Participants described experiences of financial control, exploitation, and employment sabotage. Partners leveraged the criminal–legal, child welfare, and health care systems and cultural norms about pregnancy, including those related to gender and religion to financially harm survivors. Advocates described how economic abuse impacts marginalized survivors. Dream resources described include cash assistance, healthy relationship and financial education, and employer policies. Discussion: Survivors and advocates reported a variety of experiences with economic abuse during the perinatal period. Future interventions should focus on providing unrestricted cash transfers to survivors, developing education on economic abuse, and creating supportive policies in health care and employment settings. This study highlights the ways that economic abuse specifically impacts perinatal survivors and their children. [ABSTRACT FROM AUTHOR]

To explore pediatricians' perspectives on supporting intimate partner violence (IPV) survivors, including (a) clinical practices and resource use, (b) ideal resources, and (c) barriers to the use of existing resources, we conducted dyadic and individual virtual interviews with pediatricians recruited through Twitter and the American Academy of Pediatrics Council, section, and chapter listservs. The interviews were approximately 60 minutes in length, audio recorded, and transcribed verbatim. We used a thematic analysis approach and hybrid deductive–inductive coding. Twenty-three pediatricians participated in 14 interviews. We identified four themes. Participants' current practices primarily focused on IPV screening and response to disclosure. They described strategies for IPV resource provision and decision-making involving child protective services. They identified multilevel barriers to addressing IPV, including barriers, such as time, identified in previous studies as well as barriers related to the COVID-19 pandemic, telehealth, the electronic health record, and disclosure-focused approaches. The participants desired provider-facing and caregiver-facing resources to strengthen the capacity to address IPV; some were unaware of currently available resources. They noted the need for continued attention to optimizing systems to enhance their capacity to support IPV survivors. Pediatricians report varying practices to address IPV and identify several surmountable barriers to supporting IPV survivors. Our study suggests that disclosure-driven clinical practices, confidentiality concerns, and lack of resources limit pediatricians' capacity to address IPV. Additional resource development and dissemination efforts are needed to improve the awareness of IPV resources currently available to pediatricians and families. [ABSTRACT FROM AUTHOR]

Premise: Poikilohydric plants respond to hydration by undergoing dry–wet–dry cycles. Carbon balance represents the net gain or loss of carbon from each cycle. Here we present the first standard protocol for measuring carbon balance, including a custom‐modified chamber system for infrared gas analysis, 12‐h continuous monitoring, resolution of plant–substrate relationships, and in‐chamber specimen hydration. Methods and Results: We applied the carbon balance technique to capture responses to water stress in populations of the moss Syntrichia caninervis, comparing 19 associated physiological variables. Carbon balance was negative in desiccation‐acclimated (field‐collected) mosses, which exhibited large respiratory losses. Contrastingly, carbon balance was positive in hydration‐acclimated (lab‐cultivated) mosses, which began exhibiting net carbon uptake <15 min following hydration. Conclusions: Carbon balance is a functional trait indicative of physiological performance, hydration stress, and survival in poikilohydric plants, and the carbon balance method can be applied broadly across taxa to test hypotheses related to environmental stress and global change.

Objective: The goal of this study was to partner with community organizations to understand the research experiences of communities who speak languages other than English (LOE). Methods: We conducted semi-structured qualitative interviews in Spanish, Nepali, Mandarin, French, or Kizigua with LOE community members and community leaders who completed recruitment and data collection. Audio-recordings of the interviews were transcribed and translated. We conducted qualitative coding using a mixed deductive-inductive analysis approach and thematic analyses using three rounds of affinity clustering. This study occurred in partnership with an established community-academic collaboration. Results: Thirty community members and six community leaders were interviewed. 83% of LOE participants were born outside of the US and most participants (63%) had never participated in a prior research study. Six themes emerged from this work. Many participants did not understand the concept of research, but those that did thought that inclusion of LOE communities is critical for equity. Even when research was understood as a concept, it was often inaccessible to LOE individuals, particularly because of the lack of language services. When LOE participants engaged in research, they did not always understand their participation. Participants thought that improving research trust was essential and recommended partnering with community organizations and disseminating research results to the community. Conclusion: This study's results can serve as an important foundation for researchers seeking to include LOE communities in future research to be more inclusive and scientifically rigorous.

Summary: Background: Recent pediatric guidelines recommend clinicians offer anti‐obesity medication (AOM) as an adjunct to intensive lifestyle intervention. Objective: To investigate pediatricians' perspectives about prescribing AOM, including barriers and facilitators. Methods: An investigator‐developed survey was emailed to primary care pediatric physicians (n = 187) and advanced practice providers (n = 190) within an academic‐affiliated network. The survey evaluated how willing clinicians were to prescribe AOM and their agreement with 25 statements about barriers and facilitators. Three vignettes explored AOM decision‐making. Multinomial logistic regression was used to determine relative risk ratios for willingness to prescribe by agreement with each statement. Results: Among 74 respondents (20% response rate), 24% were willing, 42% uncertain and 34% unwilling to prescribe. Most (64%) agreed that AOM should be managed only by specialists. Willingness to prescribe was associated with clinician motivation and belief in guideline practicality and applicability. Unwillingness was associated with beliefs that patients would not continue AOM long enough for benefit and that there was insufficient time or resources to implement. In vignettes, 52% were willing to prescribe AOM for a patient with severe obesity and metabolic complications, versus 11% for a patient with obesity and possible disordered eating. Conclusions: Willingness to prescribe AOM was low and was associated with perceived practicality and appropriateness for patients. [ABSTRACT FROM AUTHOR]
