Pioneer psammophytic vegetation is usually developed on wind-drift sandy substrates such as arenas, spits, beaches, river terraces, and this vegetation occupies significant areas in all three natural zones of Ukraine. The Koelerio-Corynephoretea canescentis class was represented by 13 associations, 3 alliances and 1 order; Festucetea vaginatae class by 22 associations, 2 alliances and 1 order; Helichryso-Crucianelletea maritimae by 10 associations, 4 alliances and 1 order. The results of cluster analysis and synoptic tables of the classes are presented. 9 alliances are briefly described. Leading factors of territorial and ecological differentiation are identified. It was found that the territorial distribution of plant communities is influenced by the character of ecotope mesorelief, soil composition and humus horizon thickness, as well as the degree of eolian processes development. The main factors of their ecological differentiation are soil acidity, salt regime and ombroregime. Based on the results of DCA-ordination of syntaxa within certain vegetation classes, it was found that their distribution is influenced by factors that correlate with the environment-specific conditions. It has emerged that an ecological differentiation of syntaxa within Festucetea vaginatae is determined by the integrated effect of gradients, and soil salinity is leading among them. Temperature regime and climate continentality are leading factors in the distribution of syntaxa within the Koelerio-Corynephoretea canescentis class. The gradients of ombroregime and soil humidity have a significant impact. The distribution of communities of the Helichryso-Crucianelletea maritimae class in the ecological space is determined mainly by factors of variability of damping, ombroregime and climate continentality. The author’s syntaxonomic concept assumes the independence of the studied classes: Koelerio-Corynephoretea canescentis, Helichryso-Crucianelletea maritimae and Festucetea vaginatae, conside­ring that the leading factors of community differentiation of the Festucetea vaginatae and Koelerio-Corynephoretea canescentis classes are the origin (genesis) of sandy substrates, as well as soil acidity. Phytosociological analysis of a large number of relevés of coastal littoral vegetation also provides support for independence of the Helichryso-Crucianelletea maritimae and Ammophiletea classes diffe­rent floristically and ecologically. A review of the psammophytic vegetation of Ukraine will determine the place of the selected syntaxonomic units in the pan-European system.

Published: October 2020

Human activity has disturbed the functioning of river ecosystems all around the globe. The current global climatic fluctuations and local anthropogenic impact lead to rearrangement in the structure and functioning of aquatic communities. One of the most important components of aquatic ecosystems is phytoplankton as the main primary producer of the organic matter, the basis for trophic relations and indicator of changes in the environment. This article presents the first results of a study concerning the peculiarities of quantitative distribution of biomass and species composition of phytoplankton in the delta of the Mekong River at the beginning of the dry season (December of 2018). Diatoms dominated according to biomass practically in all the stations of selection of samples. The total biomass of phytoplankton on average accounted for 0.049 ± 0.007 mg/L at the abundance of 40 ± 7 103 ind./L. In practically all the studied plots, according to biomass, the dominating diatoms were first of all Aulacoseira granulata, A. islandica, Cyclotella meneghiniana, Cyclotella spp., and Oxyneis binalis. Among Chlorophyta, most often we found Chlorella sp. and Scenedesmus quadricauda, but their biomass was insignificant. We determined statistically significant correlation relationships between biomass of phytoplankton and hydrological parameters. Based on the Spearman’s rank correlation coefficient, we determined negative relations between the total biomass of phytoplankton with salinity and pH. Positive correlation was seen between the biomass of diatoms and turbidity, and also between the temperature and the biomass of chlorophytes and Dinophyta. The biomass of golden algae (Chrysophyceae) and Dinophyta positively correlated with the mineralization. Quantitative regression analysis confirmed the close relationship between the total biomass of phytoplankton, hydrophysical and hydrochemical parameters. Besides the importance of scientific data on biological diversity and ecology of plankton algae, the results we obtained are necessary for organizing biological monitoring in the delta of the Mekong River in the future.
Influence of nanosized particles of zirconium and aluminum oxides on the properties of materials based on the Si-B<sub>4</sub>C-ZrB<sub>2</sub> composition
Authors: Nikolaev A. N. , Ban'kovskaya I. B. , Perevislov S. N. 
Published: October 2020

The effect of nanosized particles of ZrO2 and Al2O3 on physicomechanical properties (elastic modulus, flexural strength, microhardness), phase composition, and also the microstructure of materials based on Si-B4C-ZrB2 is studied. After heat treatment in air in an electric furnace, a borosilicate glass-forming melt was obtained by a reaction method, which had an encapsulating effect on the starting components. As a result, gradient glassceramic materials were obtained in which the surface glass-ceramic layer protects the underlying layers from oxidation. This approach can be used to obtain protective coatings for carbon materials. It is shown that the introduced additives improve the mechanical properties of the composites.

Authors: Nepochatov Yu. K. , Pletnev P. M. , Denisova A. A. 
Published: October 2020

The features of firing aluminitride substrates, characterized by a high temperature of more than 1800 0С and the presence of a reducing environment, are described. It is shown that the high quality of substrates in parallelism, thermal conductivity, and other properties can be achieved, along with the establishment of optimal firing modes, using a special design of a capsule based on boron nitride, which is a container that consists of a body - a box of rectangular cross section, bottom and plane-parallel dividing plates with supports. To create a local (inside the capsule) clean recovery medium, thorn-groove interlocks between the body and the bottom are provided, filled with a heat-resistant inert powder.

Published: October 2020

Background or Objectives: Women living with HIV (WLHIV) are at increased risk of depression. In pregnancy, depression could affect health and pregnancy outcomes, as well as child rearing. We assessed depressive symptoms and quality of life of WLHIV during the perinatal period.
Methods: This cross-sectional study was conducted at 15 hospitals in Chiang Mai, Thailand. The Patient Health Questionnaire-9 and the World Health Organization quality of life questionnaire (WHOQOL-BREF_THAI) were used to screen for depressive symptoms and to assess quality of life (QOL), respectively. Statistical analysis was performed by the SPSS. Descriptive statistics were reported. Factors associated with depressive symptoms were assessed by univariate and multivariate analyses. Linear regression analysis was performed to determine association between depressive symptom scores and QOL. Regression coefficient (?) and 95% confidence intervals (CI) were reported. P-values < 0.05 were considered statistically significant.
Results: One hundred WLHIV were enrolled and the mean age was 29.2 ±7.5 years. The overall prevalence of depressive symptoms was 30 (30%), 95% CI 21-39; specifically, 34 (34%) in pregnant and 27 (27%) in postpartum women. Overall, depressive symptoms were mild in 22 (22%), moderate in 7 (7%), and moderately severe in one (1%). Multivariate logistic regression analysis revealed that verbal abuse by partner (?=4.751 (95% CI=2.306-9.790), p< 0.001) and lifetime alcohol use (?=3.403 (95% CI=1.427-8.115), p=0.006) were associated with depressive symptoms. The overall perception of own health and quality of life of WLHIV in all domains were lower than that of HIV-negative women. WLHIV with depressive symptoms had a significantly lower QOL than those without.
Conclusion and Global Health Implications: In this study, the prevalence of depressive symptoms in women living with HIV was similar to that in HIV-negative women. WLHIV with depressive symptoms had a significantly lower QOL than those without. Mental health screening in antenatal and postpartum clinic is warranted.

Half graben inversion tectonics revealed by gravity modeling in the Mikawa Bay Region, Central Japan
Authors: Miyakawa Ayumu , Abe Tomoya , Sumita Tatsuya , Otsubo Makoto 
Published: October 2020

Abstract
The Mikawa Bay Region, central Japan, is characterized by many active faults recording Quaternary activities. It is, however, difficult to understand the overall tectonic character of the region due to a thick sedimentary cover. We report the first finding of Neogene basin inversion in southwest Japan by estimating the depth and structure of the basement surface in the Mikawa Bay Region by analyzing gravity data. Our gravity basement map and two-dimensional density-structure modeling revealed a half graben bounded on the south by the north-dipping Utsumi Fault. The motion of the Utsumi Fault, which inverted from normal faulting during the Miocene to recent reverse faulting, indicated the inversion of the half graben. The timing of the inversion of the fault motion, i.e. the reverse faulting of the Miocene normal fault, can be compared with an episode of basin inversion observed at the eastern margin of the Japan Sea, northeastern Japan. The Takahama Fault in the southwestern part of the Nishi–Mikawa Plain is considered to have formed as a result of the backthrust of the Utsumi Fault under inversion tectonics. If the Takahama Fault is indeed the backthrust fault of the Utsumi Fault, the root of the Takahama Fault may be deep such that the Takahama Fault is seismogenic and linked to the 1945 Mikawa earthquake.

Abstract
Background Obesity is overrepresented in patients with psoriatic arthritis (PsA) and associated with increased disease activity. We have previously shown in 41 patients with PsA (Caspar criteria) and obesity (body mass index; BMI ≥33 kg/m2) that weight loss treatment with Very Low Energy Liquid Diet (VLED), 640 kcal/day during 12-16 weeks, followed by a structured reintroduction of an energy restricted diet resulted in a median weight loss of 18.6% and concomitantly a significant improvement of the disease activity in joints, entheses and skin. The objectives of this follow-up were to study the effects of the weight loss treatment on disease activity in longer term (12 and 24 months) and to study the effects on cardiovascular risk factors. Methods The patients were assessed with 66/68 joints count, Leeds enthesitis index (LEI), body surface area, blood pressure, BMI, questionnaires and fasting blood samples at the 12- and 24-month visits.Results In total, 39 and 35 PsA patients attended the 12- and the 24-month visits, respectively. Median weight loss since baseline was 16.0 % (IQR 10.5–22.4) and 7.4% (IQR 5.1–14.0) at the 12- and 24-months follow-up. The 66/68 swollen/tender joints score, LEI, CRP and HAQ score were still significantly reduced at the 12- and 24-month visits compared to baseline. The number of patients with Minimal Disease Activity increased from 28.2% (11/39) at baseline, to 38.5% (15/39; p=0.008) and 45.7 % (16/35; p=0.016) at the 12- and 24-month visits.The weight loss was also associated with improved levels of serum lipids, glucose and urate and the antihypertensive treatment was reduced or stopped in five patients during the follow-up.Conclusions Weight loss treatment, with VLED included in the program, was associated with long-term improvement of measures of disease activity, self-reported function and markers of the metabolic syndrome after 24-months follow-up.Trial registration ClinicalTrials.gov identifier: NCT02917434, Registered September 28, 2016- Retrospectively registered. https://clinicaltrials.gov/ct2/show/NCT02917434

Published: October 2020

Abstract
Background: Bronchopulmonary dysplasia (BPD) is a severe condition in premature infants that compromises lung function and necessitates oxygen support. Despite major improvements in perinatal care minimizing the devastating effects, BPD remains the most frequent complication of extreme preterm birth. Our study reports the safety of the allogeneic administration of umbilical cord-derived mesenchymal stem/stromal cells (allo-UC-MSCs) and the progression of lung development in four infants with established BPD.
Methods : UC tissue was collected from a healthy donor, followed by propagation at the Stem Cell Core Facility at Vinmec Research Institute of Stem Cell and Gene Technology. UC-MSC culture was conducted under xeno- and serum-free conditions. Four patients with established BPD were enrolled in this study between May 25, 2018, and December 31, 2018. All four patients received two intravenous doses of allo-UC-MSCs (1 million cells/kg patient body weight (PBW) per dose) with an intervening interval of 7 days. Safety and patient conditions were evaluated during hospitalization and at 7 days and 1, 6 and 12 months postdischarge.
Results: No intervention-associated severe adverse events or prespecified adverse events were observed in the four patients throughout the study period. At the time of this report, all patients had recovered from BPD and were weaned off of oxygen support. Chest X-rays and CT scans confirmed the progressive reductions in fibrosis.
Conclusions: Allo-UC-MSC administration is safe in preterm infants with established BPD.
Trial registration : This preliminary study was approved by the Vinmec International Hospital Ethics Board (approval number: 88/2019/QĐ-VMEC; retrospectively registered March 12, 2019).

Abstract
Background: People with criminal justice involvement contribute remarkably to the rising hepatitis C virus (HCV) burden; however, the continuum of care is a major barrier to prison-based programs. We aimed to evaluate a comprehensive HCV care model in an Iranian provincial prison.Methods: Between 2017-2018, in the Karaj Central Prison, newly admitted male inmates received HCV antibody testing and venipuncture for RNA testing (antibody-positive only). Participants with positive RNA underwent direct-acting antiviral (DAA) therapy (Sofosbuvir/Daclatasvir). Sustained virological response was evaluated at 12 weeks post-treatment (SVR12).Results: Overall, from 3,485 participants, 182 (5.2%) and 117 (3.4%) tested positive for HCV antibody and RNA, respectively. Among 116 patients who were eligible for treatment, 24% (n=28) were released before treatment and 72% (n=83) initiated DAA therapy, of whom 81% (n=67/83) completed treatment in prison, and the rest were released. Of total released patients, 68% (n=30/44) were linked to care in community, and 70% (n=21/30) completed treatment, including 60% (n=12/20) and 90% (n=9/10) among those who were released before and during treatment, respectively. The overall HCV treatment uptake and completion were 89% (n=103/116) and 85% (n=88/103), respectively. From people who completed treatment, 43% (n=38/88) attended for response assessment and all were cured (SVR=100%).Conclusions: Integrated HCV care models are highly effective and can be significantly strengthened by post-release interventions. The close collaboration of community and prison healthcare systems is crucial to promote high levels of treatment adherence. Future studies should investigate the predictors of engagement with HCV care following release.
“Can Virtue Be Taught?”: A Content Analysis of Medical Students’ Opinions of the Professional and Ethical Challenges to their Professional Identity Formation
Authors: Hawking Michael , Kim Jenny , Jih Melody , Hu Chelsea , Yoon John D. 
Published: October 2020

Abstract
Background
Efforts have begun to characterize the ethical and professional issues encountered by medical students in their clinical years. By applying previously identified taxonomies to a national sample of medical students, this study seeks to develop generalizable insights that can inform professional identity formation across various clerkships and medical institutions.
Methods
In a national survey of medical students, participants answered an open-ended survey item that asked them to describe a clinical experience involving an ethical or professional issue. We coded these responses using the Kaldjian taxonomy of ethical and professionalism themes in medical education through an iterative, consensus-building process. Noting the emerging virtues-based approach to ethics and professionalism, we also reexamined the data using a taxonomy of virtues.
Results
The response rate to this survey item was 144 out of 499 eligible respondents (28.9%). All 144 responses were successfully coded under one or more themes in the original taxonomy of ethical and professional issues, resulting in a total of 173 coded responses. Professional Duties was the most frequently coded theme (29.2%), followed by Communication (26.4%), Quality of Care (18.8%), Student-specific Issues of Moral Distress (16.7%), Decisions Regarding Treatment (16.0%), and Justice (13.2%). In the virtues taxonomy, 180 total responses were coded from the 144 original responses, and the most frequent virtue coded was Wisdom (23.6%), followed by Respectfulness (20.1%) and Compassion or Empathy (13.9%).
Conclusions
Originally developed from students’ clinical experiences in one institution, the Kaldjian taxonomy appears to serve as a useful analytical framework for categorizing a variety of clinical experiences faced by a national sample of medical students. This study also supports the development of virtue-based programs that focus on cultivating the virtue of wisdom in the practice of medicine.
Ride-Hailing Services and Alcohol Consumption: Longitudinal Analysis
Authors: Burtch Gordon , Greenwood Brad N , McCullough Jeffrey S 
Published: October 2020

Background
Alcohol consumption is associated with a wide range of adverse health consequences and a leading cause of preventable deaths. Ride-hailing services such as Uber have been found to prevent alcohol-related motor vehicle fatalities. These services may, however, facilitate alcohol consumption generally and binge drinking in particular.

Objective
The goal of the research is to measure the impact of ride-hailing services on the extent and intensity of alcohol consumption. We allow these associations to depend on population density as the use of ride-hailing services varies across markets.

Methods
We exploit the phased rollout of the ride-hailing platform Uber using a difference-in-differences approach. We use this variation to measure changes in alcohol consumption among a local population following Uber’s entry. Data are drawn from Uber press releases to capture platform entry and the Behavioral Risk Factor Surveillance Systems (BRFSS) Annual Survey to measure alcohol consumption in 113 metropolitan areas. Models are estimated using fixed-effects Poisson regression. Pre- and postentry trends are used to validate this approach.

Results
Ride-hailing has no association with the extent of alcohol consumption in high (0.61 [95% CI –0.05% to 1.28%]) or low (0.61 [95% CI –0.05% to 1.28%]) density markets, but is associated with increases in the binge drinking rate in high-density markets (0.71 [95% CI 0.13% to 1.29%]). This corresponds to a 4% increase in binge drinking within a Metropolitan Statistical Area.

Conclusions
Ride-hailing services are associated with an increase in binge drinking, which has been associated with a wide array of adverse health outcomes. Drunk driving rates have fallen for more than a decade, while binge drinking continues to climb. Both trends may be accelerated by ride-hailing services. This suggests that health information messaging should increase emphasis on the direct dangers of alcohol consumption and binge drinking.
