ABSTRACT

Introduction
Although vitamin D is intimately involved in bone metabolism, the relationship between vitamin D status, as measured by serum total 25-hydroxyvitamin D [25(OH)D] concentration, and bone mineral density (BMD) is weak, particularly in non-White populations. Measurement of bioavailable 25(OH)D has been suggested as a better indicator of vitamin D status than total 25(OH)D concentration. To date, the bioavailable 25(OH)D biomarker has been explored minimally in athletic populations. The purpose of this study was to investigate the relationship between total and bioavailable 25(OH)D concentrations and BMD in collegiate athletes.

Methods
NCAA Division I basketball and swimming athletes served as study participants (n = 53; 28 females, 25 males; 28 basketball players, 25 swimmers). All participants completed dual-energy x-ray absorptiometry scans for analysis of BMD, blood draws for vitamin D measures, and diet/lifestyle questionnaires.

Results
Overall, total 25(OH)D was 80.0 + 13.9 nmol·L−1 and bioavailable 25(OH)D was 6.0 ± 1.9 nmol·L−1. There was strong disagreement between total 25(OH)D and bioavailable 25(OH)D concentrations (κ = −0.299, r = −0.129) (P = 0.100); 53% of total participants and 77% of Black participants were classified differently (low vs normal vitamin D status) based on total and bioavailable 25(OH)D criteria. Black participants had significantly lower total 25(OH)D and higher bioavailable 25(OH)D concentrations than White participants (59.5 vs 102.5 nmol·L−1 and 7.9 vs 5.4 nmol·L−1, respectively) (P < 0.001). Total 25(OH)D and total BMD were not correlated, but bioavailable 25(OH)D and total BMD demonstrated a positive correlation (r = 0.618, P < 0.01).

Conclusions
These results suggest that bioavailable 25(OH)D concentration may be a better clinical measure of vitamin D status than total 25(OH)D as related to BMD in collegiate athletes, particularly in Black athletes. Further research on the utility of the bioavailable 25(OH)D biomarker in athletes is needed.

Dentro do universo da engenharia de produção, o processo de usinagem de materiais metálicos e tratamento térmico causa tensões residuais que podem alcançar valores significativos e influenciar a durabilidade dos diversos componentes mecânicos. Definir o processo adequado para cada aplicação requer a previsão de quão elevada será a tensão gerada em função das variáveis do processo utilizado. A fim de conhecer os valores das tensões resultantes, é necessário medi-las, por exemplo, usando análise experimental de tensão, que consiste no uso de strain gauges para medir deformações em uma superfície. Logo, o objetivo deste artigo é apresentar o processo de desenvolvimento e aplicação de um kit didático educacional (KiDiTen®), versão II, automatizado, em conformidade com a formação por competência na pesquisa do ensino de Engenharia, utilizando conceitos de Física, Matemática e Teoria da Elasticidade, com o objetivo de levar o aluno ao conceito elementar da tensão mecânica, tensão elétrica e tensor de ordem 2. Utilizaram-se metodologias como Educação Baseada em Projetos, Aprendizado Baseado em Problemas e abordagem STEM (Science, Technology, Engineering and Mathematics). Comprovou-se que a metodologia adotada foi adequada, empregando diversas metodologias de ensaios.

Published: October 2021

ABSTRACT
Law enforcement officers must perform physically demanding tasks as part of their job duties. Consequently, law enforcement officers must possess an adequate level of physical fitness to perform these activities safely and effectively. Ironically, most of an officer's shift time is sedentary. This, in addition to other occupational challenges, may make it difficult for officers to develop and maintain fitness across the occupational life span. This is concerning when considering that physical fitness is associated with their occupational task performance. In this column, the unique challenges law enforcement officers experience when trying to maintain health and occupational fitness are discussed.

ABSTRACT
The Seismic Experiment for Interior Structure (SEIS) of the InSight mission to Mars has been providing direct information on Martian interior structure and dynamics of that planet since it landed. Compared with seismic recordings on the Earth, ground-motion measurements acquired by SEIS on Mars are not only made under dramatically different ambient noise conditions, but also include idiosyncratic signals that arise from coupling between different InSight sensors and spacecraft components. This work is to synthesize what is known about these signal types, illustrate how they can manifest in waveforms and noise correlations, and present pitfalls in structural interpretations based on standard seismic analysis methods. We show that glitches (a type of prominent transient signal) can produce artifacts in ambient noise correlations. Sustained signals that vary in frequency, such as lander modes that are affected by variations in temperature and wind conditions over the course of the Martian sol, can also contaminate ambient noise results. Therefore, both types of signals have the potential to bias interpretation in terms of subsurface layering. We illustrate that signal processing in the presence of identified nonseismic signals must be informed by an understanding of the underlying physical processes in order for high-fidelity waveforms of ground motion to be extracted. Whereas the origins of the most idiosyncratic signals are well understood, the 2.4 Hz resonance remains debated, and the literature does not contain an explanation of its fine spectral structure. Even though the selection of idiosyncratic signal types discussed in this article may not be exhaustive, we provide guidance on the best practices for enhancing the robustness of structural interpretations.

In Indonesian society, there are still many marriages that are not registered officially or commonly called with Siri marriage. Siri marriage is a legitimate marriage according to religion but illegitimate according to the state's rule, which in turn affects the child whose born of Siri marriage. Children born out of Siri marriage cannot get their rights especially in terms of inheritance rights. The purpose of this study is to determine whether or not there is legal protection for children born of Siri marriage in terms of inheritance rights in view of the positive laws prevailing in Indonesia. The research method used is Normative research method using statutory approach (statute approach). In Indonesia related to the protection of inheritance rights for children born of siri marriage there are some differences. The benefit of this research is to increase the knowledge of whether or not there is legal protection in terms of inheritance rights for children born from siri marriage in review of the positive law in Indonesia.

Abstract
The conventional advection-dispersion equation (ADE) has been widely used to describe the solute transport in porous media. However, it cannot interpret the phenomena of the early arrival and long tailing in breakthrough curves (BTCs). In this study, we aim to experimentally investigate the behaviors of the solute transport in both homogeneous and heterogeneous porous media. The linear-asymptotic model (LAF solution) with scale-dependent dispersivity was used to fit the BTCs, which was compared with the results of the ADE model and the conventional truncated power-law (TPL) model. Results indicate that (1) the LAF model with linear scale-dependent dispersivity could better capture the evolution of BTCs than the ADE model; (2) dispersivity initially increases linearly with the travel distance and is stable at some limited value over a large distance, and a threshold value of the travel distance is provided to reflect the constant dispersivity; and (3) compared with the TPL model, both the LAF and ADE models can capture the behavior of solute transport as a whole. For fitting the early arrival, the LAF model is less than the TPL; however, the LAF model is more concise in mathematics and its application will be studied in the future.

Abstract
Natural Gas production and transportation are at risk of Gas hydrate plugging especially when in offshore environments where temperature is low and pressure is high. These plugs can eventually block the pipeline, increase back pressure, stop production and ultimately rupture gas pipelines. This study seeks to develops machine learning models after a kinetic inhibitor to predict the gas hydrate formation and pressure changes within the natural gas flow line. Green hydrate inhibitor A, B and C were obtained as plant extracts and applied in low dosages (0.01 wt.% to 0.1 wt.%) on a 12meter skid-mounted hydrate closed flow loop. From the data generated, the optimal dosages of inhibitor A, B and C were observed to be 0.02 wt.%, 0.06 wt.% and 0.1 wt.% respectively. The data associated with these optimal dosages were fed to a set of supervised machine learning algorithms (Extreme gradient boost, Gradient boost regressor and Linear regressor) and a deep learning algorithm (Artificial Neural Network). The output results from the set of supervised learning algorithms and Deep Learning algorithms were compared in terms of their accuracies in predicting the hydrate formation and the pressure within the natural gas flow line. All models had accuracies greater than 90%. This result show that the application Machine learning to solving flow assurance problems is viable. The results show that it is viable to apply machine learning algorithms to solve flow assurance problems, analyzing data and getting reports which can improve accuracy and speed of on-site decision making process.

Published: October 2021

Introduction.Ectropion of the cervix (EC) is a condition when there is a cicatricial deformity of the uterine cervix (as a result of traumatic injuries) with visualization of the ectopic columnar epithelium on the vaginal part of it. The ectopia is currently classified as a variant of the normal histophysiological state of the cervix. This article discusses the features of the course and methods of treatment of complicated EC.Objective of the study is:to develop and evaluate the effectiveness of a new method of complex treatment of CE.Material and methods.In an open prospective study, 133 patients with CE (groups 1 and 2) and 56 healthy women (group 3) has taken part. In group 1 (n = 83), we have used a method for treating CE developed by us, which included two stages: stage I – elimination of microbial and viral pathogen in combination with immunomodulatory therapy, II – electrosurgical treatment (Leep biopsy) and treatment of the cervix with Galavit (100 mg of dry matter) dissolved in 5 ml of Miramistin (Patent for invention RU 2568768 C1). In group 2 (n = 50), surgical treatment of CE has been preceded by vaginal sanitation, empirical antibacterial and antiviral therapy. Diagnostic measures, in addition to standards, have included: determination of interleukins IL-1β, IL-6, IL-8, IL-10 in the discharge of the cervical canal, ultrasound diagnostics with Doppler measurements in the vessels of the central zone of the cervix. Statistica 7.0, SPSS 17 packages have been used for statistical processing.Results and discussion.Before the start of treatment, patients in groups 1 and 2 have been found to have a combination of CE with cervicitis (100%), ASCUS cytological picture (more than 60%), abnormal colposcopic signs (100%), imbalance of the local immune system with a predominance of Th1 cytokines (the content of IL-8 increased 2.6 times; IL-1b – 13 times; IL-6 – 20 times, and IL-10 – in 1.7 times) against the background of increased vascularization and cervical perfusion. The reparative process after Leep biopsy in group 1 has ended by the end of 3 weeks in 65.6% of patients, in group 2 – in 25.5%, after 5 weeks – in 100% and 57.4%, respectively, after 8 – in group 2, 91.5%. The average period of epithelialization of a wound on the cervix in group 1 was 27.4 ± 4.3 days, in group 2 – 39.5 ± 5.6 days (p = 0.01). After 2 years, the recurrence of cervical pathology has been recorded only in group 2 (34.0%).Conclusion.The use of the developed method of two-stage complex therapy for CE increases the effectiveness of treatment, prevents complications after Leep biopsy, accelerates epithelialization by 30.6% and avoids recurrence of the disease.

Introduction. We assessed the features of kidney injury in patients with different types of TMA during pregnancy, taking into consideration the fact that the acute kidney injury (AKI) that occurs during pregnancy or in the early postpartum period is main- ly caused by various types of thrombotic microangiopathies (TMA), and AKI itself is a serious obstetric complication with the risk of serious complications and mortality for both mother and fetus.Objective of the study. To study the features of nephropathy in different types of pregnancy-associated TMA.Materials and methods. The study included 313 pregnant women, women in childbirth and puerperas, of which 71 women had atypical hemolytic uremic syndrome (aHUS), 124 – HELLP syndrome, 70 – varying degrees of severity of PE, a group of patients with more rare causes of TMA was also identified: TTP, CAPS and sepsis (13 patients) and 45 patients for the control group. We assessed and compared the main clinical, laboratory and instrumental data, and assessed the outcome of labour. Also, histological examination of the kidneys was performed in five patients with aHUS.Results and discussion. The results of the study have shown that the most severe manifestations of TMA in the form of target organ injury and nephropathy are usually occur in patients with aHUS, where all women developed AKI, in some cases with the formation of chronic kidney disease. In the HELLP syndrome group, AKI was recorded in 39%, but renal function quickly restored. It was found that the very fact of the presence of AKI points to a more unfavourable prognosis not only for the patients themselves, but also for the child, being the main risk factor for perinatal death. The findings of urinary sediment tests and morphological evaluation indicate that the resulting ischemia of the renal tissue in cases of aHUS, HELLP syndrome and other types of TMA can lead to tubular necrosis as compared with PE. Our results suggest that it is AKI in HELLP syndrome that is the main risk factor for perinatal death. Alas, this relationship is difficult to trace in patients with aHUS, as all of them had AKI.Conclusions. Timely recognition of the AKI phenomenon in all cases of obstetric TMA can reduce the risks for both mother and fetus. Both the prognosis for mother and the prognosis for child depend on AKI, and timely therapy can lead to a regression of AKI phenomena and the complete restoration of renal function.

Introduction. The novel coronavirus pandemic makes the issue of iron deficiency in pregnancy even more urgent and forces multidisciplinary clinicians to search for modern ways to correct disorders caused by this infection.Objective. To assess the features of the course of post-covid anemia associated with combination therapy, as well as the effect of therapy on the dental health status in pregnant women.Materials and methods. 30 pregnant women (treatment group 1) in the third trimester who had coronavirus infection with mild IDA during gestation were enrolled in the prospective study. Comparison group 2: included 15 patients with mild IDA who did not have coronavirus infection during gestation. Control group 3: included 15 conditionally healthy pregnant women without IDA who did not have a novel coronavirus infection during gestation.Results. Pregnant women who had COVID-19 during gestation were significantly more likely to suffer from gum bleeding, angular cheilitis, oral erosive and ulcerative lesions. Gum bleeding was significantly more common in pregnant women with IDA against the background of coronavirus infection, than in the women in the comparison and control groups (SBI index, p < 0.05). The decrease in the normal microflora suggests the presence of dysbiotic changes in all pregnant women against the background of IDA, however, the patients after the COVID-19 infection had the most significant changes in it.Conclusions. The novel coronavirus infection, which the women had during gestation, aggravates the course of IDA, reduces the quality of life of patients with characteristic complaints (gum bleeding, angular cheilitis, oral erosive and ulcerative lesions), leads to dysbiotic oral microbiome changes. The management of this group of patients requires a systemic correction of the microflora balance, the introduction of individual oral hygiene regimens and adequate treatment of IDA using high-technology medicinal products
