Published: February 2022

Duodenal ulcer disease is uncommon in paediatric age group. Its perforation is even rarer. However, it should be kept in mind when examining children with acute abdomen especially if there are signs of shock or possibility of upper gastrointestinal bleed. We report a case of a 6 years old female child, a known case of thalassemia major and taking oral Deferasirox since two years of age. She had atypical presentation as there was no previous history of peptic ulcer disease and she only suffered epigastric pain and vomiting for a week but due to lack of proper diagnosis at a local clinic developed duodenal ulcer perforation, which was ultimately diagnosed at a tertiary care hospital and managed with Graham Patch Closure.
Keywords: Paediatric age group, duodenal ulcer, duodenal perforation, epigastric pain, Desferasirox.

Published: February 2022

O presente trabalho buscou analisar a distribuição espacial do desenvolvimento econômico em termos de Índice de Desenvolvimento Humano Municipal (IDHM) nos municípios do estado do Maranhão no ano de 2010 e algumas variáveis que podem afetá-lo. Foi calculada a estatística I de Moran para verificar a existência de autocorrelação espacial, sendo que essa indicou a formação de clusters significativos em todas as regiões do estado. O Modelo de Erro Espacial (SEM) foi utilizado para regredir a proporção de domicílios com banheiro e idade do município, que mostraram relação positiva; o percentual de população até 10 anos de idade e PEA da agropecuária, com relação negativa; e o IDHM dos municípios com o número de médicos para cada mil habitantes e fertilidade das mulheres até 17 anos de idade, que não foram estatisticamente significativos. A taxa de atividade de crianças entre 10 e 14 anos, ao contrário do esperado, afetou positivamente o IDHM dos municípios maranhenses, indicando que a contribuição dessa força de trabalho para a geração de renda pode ser maior que seu impacto negativo na educação. Além disso, verificou-se dependência espacial dessas variáveis, indicando que elas afetam também os municípios vizinhos.

Role of Mathematics in Sustainable Management Practice
Authors: Dr. Dhananjaya Reddy  , Dr. S. K. Rushma
Published: February 2022

Many people think that Sustainable Development and Mathematics are completely unrelated. The mathematical models, methods and challenges are enormous in the sustainable management practices or issues which are hugely complex, requiring more subtle scientific and mathematical and statistical tools. The mathematical and numerical models and soft system methodology rely on dynamical systems in control theory as well as practice at reconciling economic and ecological dimensions through a common modelling framework to cope with environmental management problems from a perspective of sustainability. To combine both public and social choice traditions with multi-criteria decision analysis in order to deal with sustainability paradoxes in a complex world with multiple dimensions, values and scales can be through mathematical methods .The applications of mathematical models are necessary to evaluate sustainability in quantitative terms, a large number of indicators, processes, and their interrelations must be taken into account and both present and future values of various indicators must be generated. Traditionally, sustainability is assessed based on a single aspect and using isolated indicators through the applications of mathematical philosophy.
In Situ Characterization of Corrosion Processes of As-Extruded Pure Magnesium Using X-Ray Computed Microtomography
Authors: Zhang Chi , Li Xin , Liu Keli , Tian Guangyuan , Wang Shuo , Wang Junsheng
Published: February 2022

X-ray computed microtomography was used to investigate the corrosion process of the extruded pure magnesium (Mg). The microscopic corrosion morphologies on the extruded pure Mg surface with corrosion time were observed by three-dimensional reconstruction technology. The effects of grain size and grain orientation of the extruded pure Mg on the corrosion rate were studied by the electron backscattered diffraction and first-principles calculations. It is found that the corrosion on the extruded pure Mg surface prefers to form on the grain boundary and the corrosion morphology is mainly the corrosion cracks distributed in a dendritic bifurcation state along the extrusion direction. Interestingly, these dendritic corrosion cracks are connected with the corrosion pits within the surface. The corrosion resistance of extruded pure Mg is improved slightly due to the presence of many high-energy sites at the grain boundaries that promote corrosion.
The Corrosion Behavior of Manganese Ions on the Vanadium-Containing Biotite Surface and Its Effect on Leaching Rate
Authors: Zhang Hao , Ye Guohua , Chen Ziyang , Tao Yuanyuan , Tang Yue , Hu Yujie
Published: February 2022

Leaching is the continuous separation of elements from the mineral surface which is composed of coordination polyhedrons of atoms. The interaction between surface elements and the leaching agent is the prerequisite for separation. Density functional theory calculations are used to reveal the interaction between leaching agent ions (H+), activator agent ions (Mn4+), and the vanadium-containing biotite surface. According to the calculation results, the oxidative activation acid-leaching process is simulated. In the oxidative activation acid-leaching process, the surface oxygen atoms first absorb hydrogen ions to complete the hydroxylation process and then combines hydrogen ions again to form water molecules. And when the surface tetrahedron has oxygen defects, the oxidant ions can further corrode the tetrahedral structure with oxygen defects. This corrosion can destroy tetrahedral structures. When the tetrahedral structure is destroyed, cations are released from the mineral surface into the solution. In this study, the corrosion behavior of the oxidant ion and its effect on the leaching rate is found. The separation of atoms from the surface under oxidative activation leaching environments is simulated at the atomic level, and the mechanism of the activated leaching process is revealed by electron probe, scanning electron microscopy, infrared, and other methods.

Purpose

In daily living, hands are the basic organs for manipulative tasks of the human body, and they are specialized for various motor tasks with different physical object contact situations. Insufficient strength during aging constitutes a key component of sarcopenia and is associated with subsequent disability and mortality. The simplest and very valid test for assessing general strength is the handgrip test, and the need for international standards for grip strength seems very essential. The study aimed to set normative data for different handgrip strength dimensions in an international healthy adult community.

Methods

The maximal muscle force and maximal explosive muscle force for dominant and non-dominant hand were examined across 838 subjects from 11 countries. The result values were compared with the internationally published findings for external validation.

Results

The mean value for both hands maximal strength in an adult male was 997 ± 176 N for the absolute and 11.78 ± 1.95 N/kg for the relative measure; in females, the respective values equalled 550 ± 110 N and 8.49 ± 1.79 N/kg. The mean value for maximal explosive strength in an adult male was 6473 ± 1420 N/s for the absolute and 76.47 ± 16.22 N/s/kg for the relative measure; in adult females, the respective values equalled 3506 ± 915 N/s and 54.13 ± 14.38 N/s/kg.

Conclusions

The normative reference values provided in this study may serve as an international guide for interpreting maximal and explosive handgrip strength measurements obtained from healthy adult individuals of both genders.
Physiological and physical effects associated with task constraints, pitch size, and floater player participation in U-12 1 × 1 soccer small-sided games
Authors: Jorge Santos Fernando , Figueiredo Teresa , Ferreira Cátia , Espada Mário
Published: February 2022

Purpose

The study aim was to analyse 1 × 1 small-sided games (SSGs) with and without floating players, in different pitch sizes.

Methods

Ten U-12 soccer players were divided into 2 groups. Group 1 (n = 4) performed 1 × 1 SSG and group 2 (n = 6) performed 1 × 1 + 1 SSG. Field sizes of 5 × 10 m (SSG1), 10 × 15 m (SSG2), and 15 × 20 m (SSG3) were used, all with small goals. The studied variables were heart rate (HR), total distance, explosive distance (> 12 km/h), accelerations, decelerations, maximum sprint, player load (PL) intensity and volume. The data were collected through WIMU PROTM and analysed with IBM SPSS Statistics. Descriptive analyses and comparisons between the effects of internal and external PL and SSG were performed with the Mann-Whitney U test.

Results

Increasing the pitch size in 1 × 1 and 1 × 1 + 1 SSGs led to raised total distance, maximum sprint, and PL. In 1 × 1 and 1 × 1 + 1 SSGs, the time practice was predominantly associated with HRmax intervals above 90%. Statistically significant differences were observed between 1 × 1 and 1 × 1 + 1 SSGs in explosive distance (SSG2: 46.40 ± 5.07 / 28.99 ± 4.93, p = 0.02, ES(r) = 0.82), PL intensity (SSG2: 2.03 ± 0.11 / 1.78 ± 0.12, p = 0.02, ES(r) = 0.82), HRmax (SSG1: 189.50 ± 1.91 / 199.50 ± 2.38, p = 0.01, ES(r) = 0.82), and HRmean (SSG1: 174.50 ± 3.31 / 181.75 ± 2.21, p = 0.01, ES(r) = 0.82). Floating players’ physical and physiological demands were lower compared with the other athletes.

Conclusions

The pitch size influences the physiological and physical response of young soccer players in SSGs. The demand of 1 × 1 SSG is higher compared with 1 × 1 + 1. Floating player participation could result in a fruitful strategy to adjust the training intensity of specific soccer players.
Temporal analysis of goals scored in futsal: a comparison of two models
Authors: Moraes Guilherme Armando De , Soares Vinicius Nagy , Chiminazzo João Guilherme Cren
Published: February 2022

Purpose

In futsal, the goal is the most important situation that can lead the teams to victory. The understanding of when they are scored can help adopting effective strategies, increasing the chances of victory. This study aimed to compare 2 models for analysing goals scored in futsal as a function of time.

Methods

Overall, 1122 goals were analysed in 194 matches of the 2018 Brazilian Futsal League, male adult category. The playing time was divided into four 10-minute periods (conventional model) and eight 5-minute periods (alternative model). The goal occurrence was compared with mixed models of repeated measures, and the fit of models by Akaike information criterion (AIC) and Bayesian information criterion (BIC).

Results

Both models were statistically significant (p < 0.001), indicating that the means of goals were different depending on the periods. The conventional model showed that the mean of goals was higher in the final 10 minutes (p < 0.001); the alternative model implied that from the seventh to the eighth period the mean of goals increased by 39.1% (95% CI: 0.27–0.64, p < 0.001). In addition, the 5-minute model revealed a better fit than the 10-minute model in accordance with AIC and BIC.

Conclusions

This finding suggests that more reliable models are useful for better understanding of how the frequency of crucial events, such as goals, changes in the course of a match. We provide information for the coaching staff to strategically think about the best situations for their teams to succeed in competitive matches.

Published: February 2022

Purpose

The present study assesses the extent to which delayed mechanical feedback affects technical and numerical long jump performance.

Methods

The participants were 45 first-grade students from the Department of Physical Education of Umm Al-Qura University. They were randomly divided into 3 equal groups. The first experimental group used delayed mechanical feedback, the second experimental group applied fast visual feedback, and the control group received oral explanation and guidance of a teacher. The delayed mechanical feedback condition lasted for 6 weeks. Each week included 2 units, each lasting for 90 minutes.

Results

The educational programs had a significant main effect on technical and numerical long jump performance (p < 0.05), with a large effect size, as the percentage of improvement ranged 9.95–42.32%. Also, the differences across the 3 groups were statistically significant in terms of their technical and numerical performance (p < 0.05), favouring the mechanical feedback group, except for the difference between the fast visual feedback and the teacher guidance groups.

Conclusions

The delayed mechanical feedback program had a more significant positive effect on technical and numerical long jump performance than the other 2 programs.
Infertility-related stress, social support, and coping of women experiencing infertility in Vietnam
Authors: Truong Lam Q. , Luong Thuy B. , Tran Thu , Dang Ngan H. , Nguyen Lien H. , Nguyen Trang T. , Nguyen Phuong T. H.
Published: February 2022

Background

Women with an infertility problem living in traditional and developing countries face extensive social pressure, infer-tility-related stress, and distress, which possibly affect their choices of coping strategies. The present study aims to investigate the impact of infertility-related stress and social support on coping of Vietnamese women who live with an infertility diagnosis.

Participants and procedure

A cross-sectional study was conducted with 192 women diagnosed with infertility at two hospitals in the north and central regions of Vietnam. Participants completed a questionnaire consisting of the Multidimensional Scale of Per-ceived Social Support, the Copenhagen Multi-centre Psychosocial Infertility coping scales and the Fertility Problem Inventory, and questions about their sociodemographic characteristics, infertility-related history, and key social rela-tionships. Four linear regression analyses were performed on four coping strategies: active-avoidance coping (AAC), active-confronting coping (ACC), passive-avoidance coping (PAC), and meaning-based coping (MBC).

Results

The findings show that high infertility-related stress significantly predicted the use of avoidance coping strategies (AAC and PAC) among these women, while those with a high level of perceived social support tended to use ACC and MBC. None of the four linear regression models support the moderating role of social support in the relationship between infertility-related stress and coping styles.

Conclusions

The study findings show that levels of infertility-related stress and perceived social support have a direct effect on the choice of coping strategies among Vietnamese women diagnosed with infertility. The study results have practical implications in the Vietnamese context, including: (i) the development and adaptation of evidence-based and cultur-ally appropriate interventions and counselling strategies; and (ii) social policy advocacy to better support women diagnosed with infertility, their husbands, and both as couples.

A series Schiff base macrocyclic complexes of the type [HLMX2] where M = Cu(II), Ni(II), Co(II) and X = Cl, OAc have been synthesized by condensation of 5-methylindoline- 2,3-dione and 2,2-dimethylpropane-1,3-diamine in the presence of divalent metal salt in methanolic medium. The complexes have been characterized with the help of elemental analysis, conductance measurements, magnetic measurements and their structural configuration have been determined by various spectroscopic (electronic, IR, 1H NMR, 13C NMR, GCMS) techniques. Electronic and magnetic moments of the complexes indicate that the geometries of the metal centers are octahedral. These metal complexes were also tested for their antimicrobial activities to assess their inhibiting potential.
Antiparasitic activity of Artemether and combination Artemether with Artemisinin against Leishmaniasis, in vitro.
Authors:   Department of Biology, College of Science, University of Baghdad, Al-Jaderyia Campus, Baghdad, Iraq., Hassan Ghuffran Muhammed
Published: February 2022

The Leishmania donovani parasite causes visceral leishmaniasis (VL), an acute and fatal form of leishmaniasis. Because traditional therapy alternatives, such as glucantime and other pentavalent medicines, are toxic and have side effects, new treatments with fewer negative effects are needed. Only a handful of drugs are clinically beneficial to treatments of the disease, but considerable limitations threaten their very usage. Novel, safe, and efficient drugs, including those against antimalaria and leishmaniasis co-infections, are so essential. Artemether (ATM) is an Artemisinin derivative that has been demonstrated to be useful in the treatment of malaria and, more recently, leishmaniasis. The current research was carried out to evaluate the anti-leishmanial effects of Artemether (ART) and combination of Artemether- Artemisinin (ART- ATM) against procyclic promastigotes of Leishmania donovani. In this fundamental-applied research, we compared the effect of (ATM) and combination of (ART- ATM) on Leishmania donovani procyclic promastigotes, at different concentrations by using the MTT assay method after 24 ,48 and 72 h of treatment. The results prove ATM and combination (ART- ATM) efficiency against the procyclic promastigotes viability with IC50 measured after 24, 48- and 72hours treatment. The combination of (ART- ATM) could be used in the treatment of leishmaniasis to improve the therapeutic outcome for Leishmania species.

Postural orthostatic tachycardia syndrome in children and adolescents
Authors: Lee Jeongho
Published: February 2022

Background: Postural orthostatic tachycardia syndrome (POTS) is a heterogeneous disorder in children and adolescents. Recently, there have been some data concerning the prevalence of POTS in adults. However, current studies on POTS in children and adolescents are rare. Thus, many young patients with POTS are misdiagnosed with migraine or other diseases.Current Concepts: The diagnosis and treatment of POTS differ between pediatric and adult patients. POTS in children and adolescents is diagnosed with chronic symptoms of orthostatic intolerance, such as a heart rate rise of 40 beat per minute (bpm) or a heart rate exceeding 130 bpm without orthostatic hypotension. There are three major POTS categories: hypovolemic POTS, neuropathic POTS, and hyperadrenergic POTS. These categories are distinguished by their major mechanisms. The different subtypes of POTS in children and adolescents have their own clinical characteristics and laboratory findings.Discussion and Conclusion: Treatment of POTS in children and adolescents should always include lifestyle changes, nutritional adjustments, exercise, and drugs depending on the different subtypes of POTS.

Effectiveness of health and safety training in reducing occupational injuries among harvesting forestry contractors in KZN
Authors:   , Nkomo Gladys Hloniphile
Published: February 2022

Work related injuries are of major public importance and have adverse economic and social impacts. Forestry work is one of the most hazardous occupations worldwide and accounts for a large proportion of occupational injuries. Employers frequently train workers in the proper and safe use of equipment, however the efficacy of these programmes are seldom rigorously evaluated. The aim of this study was to assess the effectiveness of health and safety training in reducing injuries among forestry workers in Kwa-Zulu Natal. A descriptive study was conducted among 300 Kwa-Zulu Natal harvesting contract workers. A questionnaire to assess the efficiency of health and safety training was administered. A retrospective review of the injury register and medical records of employees who sustained work related injuries, fatalities during 2009–2013 was done. The company injury data for harvesting contractors from 2009- 2013 reported 3 fatalities and 68 lost time injuries during post commencement of training. About 23.3% workers reported injuries during the study period. Slip, trip and fall injuries were the most reported cause of injuries. Almost 95% of respondents reported that they had received health and safety training at work, with 84% reporting satisfaction with the quality of training received. A decreased prevalence of work related injuries was reported post training. The health and safety program was successful in increasing workers awareness and responsibility of health and safety issues. On- going specific job training, sustained work place inspections and adult learning for supervisors will improve health and safety of workers and reduce injuries in the forestry industry.
Concurrent validity of the Afrikaans versions of the Neck Disability Index Questionnaire and the Quadruple Visual Analogue Scale
Authors:   , Le Roux Stephanus Christoffel Jacobs
Published: February 2022

Background: Neck pain is a condition that is becoming more common throughout the world and most people can expect to experience some degree of neck pain sometime during their life. There is a need for early diagnosis and follow-up of neck pain to assess a patient’s level of self-rated disability due to the escalating disability burden and compensation costs associated with neck pain. For this reason, disability questionnaires are increasingly used for clinical assessment and as an outcome measurement for the treatment of neck pain. Translation and cross-cultural adaptation of disability questionnaires have thus become increasingly necessary when dealing with different cultural groups. Methods: This is a quantitative validity and reliability assessment study comparing the English versions of the Neck Disability Index (NDI) and the Quadruple Visual Analogue Scale (QVAS) to their translated Afrikaans counterparts. The first step was to translate the questionnaires into Afrikaans. The translated questionnaires were then scrutinised and critiqued by an Expert group, who are fluent in both the Afrikaans and English languages, and back translated to English in order or establish their face validity. A small pilot study was conducted with the original and translated versions of the questionnaires to establish their content validity. The translated and original versions of the NDI and QVAS were given to a study group to complete with a suitable time delay between the completions of the questionnaires. The results from the study group were statistically analysed to establish concurrent validity and reliability. Results: There were 50 participants each completing one English NDI and QVAS and one Afrikaans NDI and QVAS. The results indicate high reliability for both the Afrikaans NDI (α = 0.900) and QVAS (α = 0.883). The Afrikaans NDI and QVAS are deemed reliable compared to their English counterparts. The results indicated a significant level of concurrent validity for both the NDI and the QVAS. Both the Afrikaans versions of the NDI and QVAS were deemed reliable and concurrent validity was established. The NDI and QVAS were successfully translated and the Afrikaans versions can now be used in the Afrikaans population as viable alternatives to the English NDI and QVAS.

Published: February 2022

This study aimed at determining and evaluating the prevalence of gallstones in the Black population of District 28 (D28) in relation to age, gender, diet and body mass index (BMI) in order to identify people at high risk and advise them so that they can avoid the complications and decrease the morbidity rate. Blacks are thought to have increased prevalence of gallstones but there has been no systematic evaluation of its prevalence in D28. METHODS AND MATERIALS 389 Black people from D28 were selected from referrals (for many different radiological examinations) coming to the X-ray and ultrasound departments. Some of the respondents were staff members who also met the selection criteria for the study. An interview was conducted at Ngwelezane hospital using a structured questionnaire on health, social and diet history of the respondents. All information was entered into the data sheet. All respondents were then scanned using Mid-range ultrasound machines to establish the presence of gallstones and this information was thereafter documented on the data sheet. SPSS version 11.5 (SPSS Inc, Chicago, III) was used for data analysis. Prevalence and 95% confidence intervals were calculated using the Epitable module of Epi Info version 6.04 (CDC, 2001). Pearson's Chi square tests were used to assess associations between categorical variables and gall stones. Logistic regression analysis was applied to assess the independent effects of multiple risk factors on the development of gallstones. Backwards elimination method based on likelihood ratios was used with entry and exit probabilities set at 0.05 and 0.1 respectively

The purpose of this investigation was to evaluate the efficacy of homoeopathic simillimum treatment in menorrhagia, with reference to the patient's perception to the treatment as well as the amount and duration of uterine bleeding in order to determine the role of homoeopathic simillimum treatment in menorrhagia. Thirty patients were selected by convenience sampling from the greater Durban area in response to various advertisements. The patients were selected according to certain criteria including the confirmation of the diagnosis and exclusion of organic pelvic disease, infections and any complications of pregnancy as the cause of the heavy uterine bleeding by a registered gynaecologist. Once the patient was accepted as part of the study and a consent form signed, a complete homoeopathic case history and physical examination was done by the researcher. The patient then completed the first questionnaire with the researcher during the initial consultation so as to establish a baseline before treatment commenced. A menstrual chart/calender was given to the patient to record the duration and pattern of the menstrual cycle. The patient completed a new questionnaire at each follow-up for a period of three months. The study followed a double-blind protocol with a neutral member randomly dividing the sample into a control and treatment group by using a table of random numbers. The control group received placebo treatment. The patient was reassessed monthly and the questionnaire was collected by the researcher.

What Circulates on Partisan WhatsApp in India? Insights from an Unusual Dataset
Authors: Chauchard Simon , Garimella Kiran
Published: February 2022

In countries ranging from the Philippines to Brazil, political actors have embraced WhatsApp. In India, WhatsApp groups backed by political parties are suspected of conveying misinformation and/or of circulating hateful content pointed towards minority groups, potentially leading to offline violence. They are also seen as one of the reasons for the dominance of the ruling party (the BJP). Yet, despite this narrative, we so far know littleabout the content shared on these partisan groups nor about the way in which (mis-)informationcirculates on them. In this manuscript, we describe the visual content of 533 closed threads maintained by party workers across the state of Uttar Pradesh, collected over aperiod of 9 months. Manual coding of around 36,000 images allows us to estimate the amount of misinformation/hateful content on one hand, and partisan content on the other. Additional matching of this data with other sources and analyses based on computer vision techniques inturn allows us to evaluate the extent to which the content posted on WhatsApp threads may serve the interests of the ruling party. Analyses suggest that partisan threads contain relatively few hateful or misinformed posts; more surprisingly maybe, most content cannot easily be classified as “partisan”. While much content appears to be religion-related, which may serve an indirect partisan role, the largest share of the content is more easily classifiable as phatic or entertainment related.
Googling for Abortion: Search Engine Mediation of Abortion Accessibility in the United States
Authors: Mejova Yelena , Gracyk Tatiana , Robertson Ronald
Published: February 2022

Among the myriad barriers to abortion access, crisis pregnancy centers (CPCs) pose an additional difficulty by targeting women with unexpected or “crisis” pregnancies in order to dissuade them from the procedure. Web search engines may prove to be another barrier, being in a powerful position to direct their users to health information, and above all, health services. In this study we ask, to what degree does Google Search provide quality responses to users searching for an abortion provider, specifically in terms of directing them to abortion clinics (ACs) or CPCs. To answer this question, we considered the scenario of a woman searching for abortion services online, and conducted 10 abortion-related queries from 467 locations across the United States once a week for 14 weeks. Overall, among Google’s location results that feature businesses alongside a map, 79.4% were ACs, and 6.9% were CPCs. When an AC was returned, it was the closest known AC location 86.9% of the time. However, when a CPC appeared in a result set, it was the closest one to the search location 75.9% of the time. Examining correlates of AC results, we found that fewer AC results were returned for searches from poorer and rural areas, and those with TRAP laws governing AC facility and clinician requirements. We also observed that Google’s performance on our queries significantly improved following a major algorithm update. These results have important implications concerning health access quality and equity, both for individual users and public health policy.
