Алиментарный фактор по-прежнему остается одним из основных в развитии железодефицитных состояний. Обогащение пищевых продуктов железом считается наиболее экономически эффективным подходом к снижению распространенности дефицита железа. Соединения железа, используемые для обогащения пищевых продуктов, должны быть отобраны с учетом их высокой биодоступности и минимальной способности вызывать неприемлемые изменения потребительских качеств пищевого продукта. Поиск соединений железа, одновременно эффективных для коррекции недостаточности железа и обладающих приемлемыми технологическими свойствами, остается актуальной проблемой. Цель исследования – на основании сравнения свойств различных соединений железа выбрать соединение, оказывающее максимальный клинический эффект по улучшению статуса железа и минимальное влияние на свойства обогащаемого пищевого продукта. Различные соединения железа характеризуются разной растворимостью в воде и желудочном соке, обладают разной биолоступностью для организма, способностью вызывать перекисное окисление в продукте. Бисглицинат железа хорошо растворим в воде, биодоступность железа из него (включение в эритроциты) в 3-4 раза превышает таковую для использующегося в качестве эталона сравнения сульфата железа. Улучшение гематологических показателей при приеме бисглицината железа достигается при более низких дозах, чем при использовании сульфата железа. Сравнение свойств и эффективности ряда соединений железа позволяет сделать вывод о несомненных преимуществах применения для обогащения пищевых продуктов хелата бисглицината железа по сравнению с другими формами железа.

Les bénéfices de la biodiversité fonctionnelle, notamment en terme de lutte contre les ravageurs, font l'objet de débats entre les praticiens et on sait peu de choses sur les pratiques et les motivations des agriculteurs pour favoriser cette biodiversité. Nous avons supposé que l'utilisation de méthodes de suivi aiderait les agriculteurs à mieux apprécier les bénéfices de la biodiversité fonctionnelle et les inciterait à mettre en œuvre des pratiques qui lui sont favorables. Nous avons mis en œuvre une approche globale combinant des entretiens semi-directifs et des ateliers participatifs pour décrire les pratiques et la perception des agriculteurs vis-à-vis de la biodiversité fonctionnelle et concevoir des méthodes de suivi adaptées à leurs besoins. Nos résultats fournissent des preuves empiriques que la biodiversité fonctionnelle est associée à de multiples services et dis-services. En outre, ils montrent que l'expérience et le temps disponible des agriculteurs sont deux conditions importantes à la mise en œuvre de pratiques favorables à la biodiversité fonctionnelle. Quatre attitudes principales envers la gestion de la biodiversité fonctionnelle ont été caractérisées : attentisme, naturalisme, régulation et multifonctionnalité. La connaissance de ces attitudes fournit un cadre utile pour concevoir des outils de soutien et des programmes de recherche en adéquation avec les besoins des agriculteurs.

On images on plane and colorings of k-planar graphs
Authors: Karpov Dmitry Valerievich
Published: April 2023

A graph is called k-planar if it can be drawn on the plane in such a way that each edge intersects at most k others. Probably, for the first time such a generalization appeared in the work of Ringel in 1965 - 1-planar graphs were considered there and it was proved that any such graph has a regular coloring of vertices in 7 colors. Later, k-planar graphs were defined for all natural k, questions about the estimate for the number of edges in such graphs, the estimate for the chromatic number, and various questions about their images on the plane were studied. The report will talk about classical and modern results from this area.

Kaolinite Effects on Injectivity Impairment: Field Evidence and Laboratory Results
Authors: Renna S. , Sabatino L. M. F. , Viareggio A. , Rossi L. , Colombo M. , Parisi S.
Published: April 2023

Clay interaction with fluids is a well-known phenomenon that depends on formation mineralogy. This paper focuses on the impact of kaolinite clay dispersion on well injectivity impairment. It is based on field evidence from more than 50 injectors, and it is supported by a huge set of laboratory tests.

All analyzed wells showed an initial injectivity lower than the theoretical potential, estimated on the basis of reservoir quality and drawdown mobilities (DDMs). This impairment occurs before connecting wells to the injection network; therefore, injected water quality and network conditions do not take part in the damage. Consequently, the impairment mechanism seems to be correlated to the interaction between the formation and drilling fluids.

A set of laboratory experiments was planned on cuttings collected in two recently drilled wells. Different intervals were selected in the reservoir sandstones, representative of the facies where injected water is most likely to flow. Samples were first mineralogically characterized by different laboratory techniques: Fourier-transform infrared (FT-IR) spectroscopy, X-ray diffraction, and cation exchange capacity. Then, swelling and recovery tests were performed using different fluids: mud (field formulation), mud filtrate, and water (varying pH and salinity). Results were correlated with petrophysical analysis, mercury injection tests on cores, and major injectivity impairments observed on the analyzed wells.

Analyzed samples showed the presence of kaolinite that may affect the formation permeability by filling porosity and pore throats (diagenetic effect). Moreover, in case of interaction with fluids, kaolinite can lead to an additional permeability reduction by disaggregation and dispersion phenomena.

Laboratory tests showed a clear trend: The higher the kaolinite content is in the selected intervals, the higher the observed disaggregation will be, especially when the samples interact with mud filtrate and water. It was observed that mud formulation is effective, allowing to preserve disaggregation, but only below a threshold of kaolinite content.

Field experience proved that the only effective remedial actions to restore the well injectivity potential are fracturing jobs, allowing bypass of the near-wellbore damaged zone.

Published: April 2023

Background
Up to 70% pregnant women in Africa have an intestinal parasitic infection (IPI), but their adverse birth outcomes (ABOs) remain unclear. Sao Tome & Principe (STP) is an IPI high-endemic country but there is a paucity of data. This study aimed to identify an association between ABOs -maternal anaemia, prematurity (PTB), low-birth-weight (LBW) and stillbirths- and IPI in pregnant women.
Methods
A hospital-based cross-sectional study was conducted among pregnant women admitted for delivery. ANC pregnancy cards were checked for coproparasitological results, treatments, and haemoglobin levels. A structured questionnaire was administered to assess sociodemographic factors. Newborn records were used for ABOs. Pregnant with a monoparasitic-IPI (n=145) and polyparastic-IPI (n=25) were compared to noninfected-group (n=151) for ABOs. IPI-subgroups: helminthiasis (n=162), schistosomiasis (n=11) and amebiasis (n=7), were each compared to the noninfected-group. Chi-square and Fisher´s exact tests were used to identify associations between ABOs and IPI in pregnant women at p-value<0.05.
Results
A total of 361 pregnant women with a mean age of 26.96 (SD: 7.00) were included. From the 210 positive coproparasitological exams, 90.9% had Ascaris lumbricoides, followed by 13.8% Trichuris trichiura, 5.2% Schistosoma intercalatum and 3.3.% Entamoeba histolytica. Anaemia in monoparasitic-IPIs (145) was 46.7% compared to 38.7% in noninfected-group. ABOs in monoparasitic-IPI-women were 6.2% PTB, 11% LBW and 3.4% stillbirths, without any statistically significant difference (p=0.175, p=0.07, p=0.275), respectively, when compared with noninfected-women. ABOs for polyparasitic-IPI compared with noninfected-group also showed no statistically significant difference. A statistically significant difference was also not found for the subgroup’s helminthiasis, schistosomiasis and amebiasis when compared with noninfected pregnant women.
Conclusion
The lack of ABOs in our study can be related to the predominant type –Ascaris lumbricoides– a low pathogenicity parasite. This study is a useful starting point for health policy development for pregnant women in a high-IPI endemic country.

Published: April 2023

Background:Major depressive disorder (MDD) in adolescence seriously endangers their mental and physical health and is associated with poor social and scholastic function. However, the diagnosis biomarkers for adolescent with MDD remain unclear.Methods：A total of 114 adolescent subjects were enrolled in this study, the comprehensive clinical and cognitive assessments were performed. Differential expressions of lncRNAs and mRNAs of plasma exosomes were screened by microarray assay. Two sets of ceRNA (lncRNAs-miRNAs-mRNAs) networks had been generated and candidate genes had been screened by bioinformatic analysis, and candidate genes were validated in cohort using qRT-PCR.Results：A total of 3752 differentially expressed lncRNAs and 1789 differentially expressed mRNAs were identified. AC156455.1, miR-126-5p, AAK1 and CCDC18AS1, miR-6835-5p, CCND2 were picked from each network as candidate genes. We found that the six candidate genes were differential expression between MDD patients and healthy controls, or before and after antidepressant treatment of MDD group. The expression levels of AAK1, CCDC18AS1 and miR6835 varied in efficacy after 8-week sertraline treatment. We also found that the expression of CCDC18AS1, miR-6835-5p, CCND2 (in the same network) at baseline could predicted antidepressant efficacy, which may be mediated through reducing suicidal ideation and improving cognitive function.Conclusion:Our study identified and validated the plasma exosome-derived ceRNA networks altered in adolescent with MDD, our findings provided potential diagnosis and therapeutic biomarkers for adolescent with MDD.

Aged gametes and age-related metabolic diseases are common causes of reduced fertility, a pattern intimately linked with lower quality of the DNA content. D-galactose administration in rodents has been used in research related to aging. Nutraceuticals containing anthocyanins, such as açai berry (Euterpe oleracea Martius), are adjuvants in controlling or preventing diseases related to metabolic syndrome. Seventy days old male Wistar rats were induced to senescence using daily doses of 200 mg/kg b.w. of D-galactose for 8 weeks by gavage and supplemented (DGA group) or not (DG group) with 200 mg/kg of lyophilized açai berry. The sham control (C group) group received distilled water. The animals were tested for blood glucose level and regularly weighed. Reproductive organs were collected, weighed, and sperm was collected from the epididymis cauda for DNA fragmentation test (SCSA), protamination (CMA3), lipid peroxidation (BODIPY C11), acrosome integrity (PNA) and mitochondrial mass (MitoTracker Green), all performed under flow cytometry. Rats from DG group showed opaque, dry and thin fur, characteristics not seen in the DGA and C groups. In the DG group there was a statistically significant increase in the epididymis weight, and increased numbers of spermatozoa with DNA fragmentation and altered acrosome, accompanied by higher levels of lipid peroxidation, and reduced mitochondrial mass. The results presented here suggest that the rats supplemented with lyophilized açai had improved integrity of the chromatin, acrosome, and mitochondrial function when compared to the aged group, which could improve the chances of success of conception.
The impact of green financial development on stock price crash risk from the perspective of information asymmetry in Chinese listed companies
Authors: Zhang Zhibin , Ding Youqiang
Published: April 2023

Solving the crash risk problem of corporate stock price caused by information asymmetry can mitigate the negative externality of its carbon emission to become green, low-carbon, and high-quality development. Green finance generally profoundly impacts micro-corporate economics and macro-financial systems but remains a giant puzzle of whether they can effectively resolve the crash risk. This paper examined the impact of green financial development on the stock price crash risk using the sample data of non-financial listed companies in Shanghai and Shenzhen A stock market in China from 2009 to 2020. We found that green financial development significantly inhibits the stock price crash risk; this is more obvious in listed companies with a high level of asymmetric information. And companies in high-level regions of green financial development attracted more attention from institutional investors and analysts. As a result, they disclosed more information about their operational status, thus reducing the crash risk of corporate stock price from the torrential public pressure of lousy environmental details. Therefore, this study will help continuously discuss the costs, benefits, and value promotion of green finance for synergy between corporate performance and environmental performance to improve ESG capabilities.

Hexagonal boron nitride (hBN) has been a centre of interest due to its ability to host several bright quantum emitters at room temperature. However, the identification of the observed emitters remains challenging due to spectral variability as well as the lack of atomic defect structure information. In this work, we report two new blue quantum emitters with zero phonon line (ZPL) centred around 460 nm and 490 nm in hBN powders. We further demonstrate that the blue emissions can be created by high temperature annealing or high energy ion irradiation in exfoliated hBN flakes. Scanning transmission electron microscopy (STEM) reveals that the dominant defect structures present in ion irradiated sample are vacancy-type (V­x­) and adatom(intercalant)-type (A­x­). Together with first principle GW-BSE (Bethe-Salpeter equation) calculation, the observed blue emissions at 490 nm may be due to boron intercalants (Bint). Our results not only discover a new group of blue quantum emissions in hBN, but also provide an insight on the physical origin of the emissions by correlating the emission wavelength with local atomic structures in hBN.

Objectives: To assess the value of National Metabolic Management Centers (MMC) specialized online equipment for the maintenance of metabolic control among patients with type 2 diabetes (T2DM).
Patients: Between June 2017 and April 2021, patients with T2DM with at least one follow-up visit with HbA1c detected from 10 MMCs were enrolled and divided into non and application of online equipment (non-AOE and AOE) groups.
Measurements: Propensity score matching (PSM) was used to balance the characteristics of patients between groups. The change in glycated haemoglobin (HbA1c) was used to evaluate the effect of online equipment on diabetic management. Further stratified analyses were performed to assess the metabolic outcomes in subgroups.
Results: After PSM, 12528 patients with T2DM were finally enrolled. After a median (IQR) follow-up of 15.88 (7.10, 24.27) months, the AOE group showed better control of HbA1c than non-AOE group (-0.90 [-2.60, 0.00] % vs. -0.70 [-2.20, 0.10] %, P < 0.0001) and high frequency AOE group showed better control of HbA1c than low frequency AOE group (-1.50 [-3.60, -0.30] % vs. -0.80 [-2.38, 0.10] %, P < 0.0001) after adjustment. More decrease in body mass index (BMI) was observed in AOE group. Stratification analyses showed that significant between-group change in HbA1c was observed in those with lower education level or poor control of HbA1c at baseline.
Conclusions: Applying online equipment promotes better metabolic improvement and offers an alternative to out-of-hospital patient care in patients with T2DM, especially with lower education level or poorer control of HbA1c at baseline.

Published: April 2023

Objective: Type 2 diabetes is the most common type of diabetes, accounting for the majority of cases. Self-care practices among type II diabetics improve the quality of life and reduce treatment costs. Dietary adherence is one of the self-care practices. This research was conducted with the aim of using the HAPA model to improve dietary adherence among type 2 diabetics in Zahedan.
Methods: In this cross-sectional study, 210 type-2 diabetic patients admitted to hospital clinics in Zahedan during the summer of 2022 were selected (code: IR.ZAUMS.SPH.REC.1400.392). The clinics were selected by coin flipping. The intervention group (105 people) was from the diabetes clinic at Bu Ali Hospital, and the control group (105 people) was from the diabetes clinic at Khatam Al-Anbia Hospital in Zahedan. Sampling was done by simple random sampling among the diabetic patients. After collecting the data using the demographic characteristics questionnaire and the standard questionnaires, i.e., the Dietary Adherence Questionnaire and HAPA model constructs questionnaire, the pre-test analysis was done. Then the four-session educational intervention was conducted in the form of lectures, educational booklets, and behavior self-report booklets. One and three months after the educational intervention, the questionnaires on HAPA model constructs and self-care behavior were filled out by the patients and collected for analysis. Data were analyzed using independent t, chi-square, and Shapiro-Wilk tests in SPSS version 23 software.
Findings: The results showed that all the HAPA model constructs, including risk perception, outcome expectancies, behavioral intention, action self-efficacy, coping self-efficacy, recovery self-efficacy, action planning and coping planning, perceived barriers, perceived benefits, and self-care behavior had significant differences in one month and three months after the educational intervention (P = 0.001), which indicated the effectiveness of education in the intervention group. However, there was no significant difference in the control group (P = 0.009).
Discussion and conclusion:The intervention using the HAPA model showed that after the training, the model constructs had a significant impact on the patients' self-care regarding dietary adherence. Appropriate programs with details on action planning and coping planning should be developed to promote dietary adherence among patients with type 2 diabetes.
Private Benefits, Public Harms, and Citizen Participation in Corruption: a Field Experiment in Nairobi, Kenya
Authors: Yenkey Christopher , Simpson Brent , Bliese Paul
Published: April 2023

In a two-stage field experiment (N = 1,403) in Nairobi, Kenya, we demonstrate that citizens’ own self-interest legitimates common instances of corruption but concerns for harming others subsequently attenuates real willingness to participate in it. An in-person vignette experiment that manipulates the reason bribes are commonly paid demonstrates that public support for bribery is highest when bribes function as a cooperative arrangement with officials that helps citizens avoid consequences of their own mistakes and misdeeds, even though participants also recognize that these self-interested bribes cause significant harm to other citizens and institutions. In a follow-up behavioral experiment, the same respondents were offered an opportunity to cooperate with a corrupt official to receive a disproportionate cash payment following their participation in the study. Willingness to engage in the corrupt transaction was significantly reduced by a subtle reminder that accepting the additional funds could result in monetary loss to other citizens. We compare our results to earlier work using laboratory-based bribery games and discuss the potential for anti-corruption strategies based on the same types of social group preferences normally regarded as detrimental to macro-level collective action.

Background:
Favipiravir, an anti-influenza drug, has in vitro antiviral activity against SARS-CoV-2. Clinical trial evidence to date is inconclusive. Favipiravir has been recommended for the treatment of COVID-19 in some countries.
Methods:
In a multicentre open-label, randomised, controlled, adaptive platform trial, low-risk adult patients with early symptomatic COVID-19 were randomised to one of ten treatment arms including high dose oral favipiravir (3.6g on day 0 followed by 1.6g daily to complete 7 days treatment) or no study drug. The primary outcome assessed in a modified intention-to-treat population (mITT) was the rate of viral clearance (derived under a linear mixed-effects model from the daily log10 viral densities in standardised duplicate oropharyngeal swab eluates taken daily over 8 days [18 swabs per patient]). The safety population included all patients who received at least one dose of the allocated intervention. This ongoing adaptive platform trial is registered at ClinicalTrials.gov (NCT05041907).
Results:
In the final analysis, the mITT population contained data from 114 patients randomised to favipiravir and 126 patients randomised concurrently to no study drug. Under the linear mixed-effects model fitted to all oropharyngeal viral density estimates in the first 8 days from randomisation (4,318 swabs), there was no difference in the rate of viral clearance between patients administered favipiravir and patients receiving no study drug -1% (95% CI: -14 to 14% change). High dose favipiravir was well tolerated.
Interpretation:
Favipiravir does not accelerate viral clearance in early symptomatic COVID-19.

Published: April 2023

Background Neck injury is a common and often debilitating injury among athletes participating in American football. Limited data exists regarding neck injuries among elite athletes in the National Football League (NFL). To characterize the epidemiology of non-season ending, season-ending, and career-ending neck injuries in the NFL from 2016 through 2021. Methods Athletes who sustained neck injuries were identified using the NFL’s injured reserve (IR) list between the 2016 and 2021 seasons. Demographics and return to sport (RTS) data were collected. Available game footages were reviewed to identify the mechanism of injury (MOI). Injury incidence rates were calculated based on per team play basis. Results During the 6-year study period, 464 players (mean age 26.8 ± 3.2 years) were placed on the injury reserve list due to neck injuries. There were 285 defensive players and 179 offensive players injured (61.4 vs 38.6%, respectively, p < 0.001). Defensive back was the most common position to sustain a neck injury (111 players, 23.9%). 407 players (87.7%) sustained non-season-ending injuries with a mean RTS at 9.2 ± 11.3 days. 36 players (7.8%) sustained season-ending injuries with a mean RTS at 378.6 ± 162.0 days. 21 players (4.5%) sustained career-ending injuries. The overall incidence of neck injuries was 23.5 per 10,000 team plays. The incidence of season-ending injuries and career-ending injuries were 1.82 and 1.06 per 10,000 team plays, respectively. There were 38 injuries with available footages for MOI assessment (23 non-season-ending, 9 season-ending, 6 career-ending). Head-to-head contact was seen in 15 injuries (39.5%), head-down tackling in 11 injuries (28.9%), direct extremity-to-head contact in 7 injuries (18.4%), and head-to-ground contact in 5 injuries (13.2%). There was no significant difference in age, position, or MOI among players sustaining non-season-ending, season-ending, and career-ending injuries. Conclusion There is a high incidence of neck injuries among NFL athletes with predictable MOIs including head-to-head contact, head-down tackling, direct extremity-to-head contact, and head-to-ground contact. Defensive players were more likely to sustain neck injuries compared to offensive players. Defensive back was the most common position to sustain a neck injury.Level of Evidence:III

Published: April 2023

AIM OF THE STUDY: To explore the reasons why Palestinian mothers stop breastfeeding(BF) before six months of baby age.
METHODS: A cross-sectional study was conducted in Hebron/ Palestine that included mothers of all 420 live singleton newborns in the period between ( January 1, 2022, and July 31, 2022 ). Mothers who did not initiate breastfeeding or continued to breastfeed, either exclusively or with supplementation, were excluded beyond the first six months of life.
The information about BF status at 6 months of baby age and reasons for stopping BF was collected by Public health doctors and midwives through face-to-face interviews when women visit the clinic for 6-month baby vaccination and family planning consult.
RESULTS: Of all the 420 participant mothers,300 stopped breastfeeding completely before six months of baby age, among them, only 281 gave an obvious reason for stopping breastfeeding,(30%) stopped breastfeeding because of scanty milk production, (28.8%) child weaning him/herself, (24.8%) show that returning to work is the main cause, fatigue, and painful nipples were (8.4%) and mother preference was (4%).
CONCLUSION: This study highlights the reasons why women stop breastfeeding completely before six months. The results may help in identifying interventions for prolonged breastfeeding periods.

Precise detection of recurrence in patients with treated nasopharyngeal carcinoma (NPC) facilitates timely intervention and prolongs survival. However, there is no compelling tool realizing real-time precise recurrence detection as scale hitherto. Here we present a deep learning-based sequential scan model called RAIN, harnessing 10,212 time-series follow-up head and neck magnetic resonance (MR) scans of 1,808 patients with treated NPC in a multicenter observational study (Blinded ID). The RAIN yields larger area under the receiver operating curve (AUC) values than single scan model (internal: 0.916 vs 0.855, p = 0.004; external: 0.900 vs 0.709, p < 0.001). The reader study showed RAIN has superiority in timely detection of recurrence than readers. These findings suggested that RAIN could detect recurrence on MR scans with high precision and therefore be implemented in clinical practice to optimize recurrence surveillance in treated NPC.
