Published: February 2021

AbstractThe present research is aimed to evaluate the diverse husbandry practices, ethno-veterinary practices, socio-economic status and distressing constraints of camel pastoralists inhabiting desert (Thal) areas of Pakistan, where they maintain herds of Marecha and Barela dromedaries in extensive production regimes. For this purpose, 200 pastoralists were selected at random to fill out an on-site questionnaire. According to the farmers’ responses, it was perceived that their living status had improved in the last decades due to the progressive optimization of camel productivity and herdsmen responsiveness. In contrast, calf mortality rates, some traditional husbandry practices and the lack of market investments continued to be the major constraints affecting camel overall production. Ethno-veterinary medicines are widely applied as primary health care, thus influencing the general health, production potentials and relief of camels in the study region. With this scenario, concerned stakeholders and authorized institutions must re-evaluate the urgent needs of indigenous communities; their education and husbandry skills to promote economic/ financial support in low-income remote areas. In turn, traditional communities will be adapted to the changing socio-economic and cultural values with regard to camel husbandry and welfare. Current societal perceptions and demands within this livestock production industry, where camels are conceived as a sustainable food security animal, if accomplished to the highest possible extent, will increase effectiveness of the camel value chain and breeders’ quality of life will be noticeably enhanced. However, this success could be multiplied if government may devise community education, veterinary cover, marketing facilitates and interest-free small loans for pastoralists.
Understanding ‘culture’ of pastoralism and ‘modern development’ in Thar: Muslim pastoralists of north-west Rajasthan, India
Authors: Ghai Rahul 
Published: February 2021

AbstractThe paper attempts to understand the relation between pastoral cultures and irrigation-based intensive farming regimes promoted by modern development represented by the Indira Gandhi Canal (IGNP) in western Rajasthan. Participant observation and development practice engagement with pastoral communities over the past three decades give an opportunity to reflect on epistemic rationality that constitutes the discourse of modern development, formal statecraft of technocracy, and rule by experts. Historical markers of pastoralism in the interconnected regions of north-west Rajasthan and bordering regions of Multan and Bahawalpur in Pakistan are situated to trace thelonguee dureeof pastoral life systems in the Thar desert region. This oscillation between enhanced moisture regimes following inundation and increased desiccation of a moisture-deficient arid region has been at the core of sustaining the culture of pastoralism among semi-nomadic pastoralists of Muslim communities in north-west Rajasthan. The IGNP canal produces a space for modern development that opens up irrigated farming and an intensive natural resource use regime. This political economy of the IGNP canal systematically marginalizes pastoral natural resource use that was ecologically embedded. The varied experiences of adaptation responses by pastoral communities to this state-led marginalization points to the tenacious ability of pastoralism to continually adapt to the radically changing ecology. The paper argues for a complementarity of pastoral and farming use as an inclusive development vision. Beginnings can be made by a compassionate engagement with cultures of pastoralism that are endowed with resilience rooted in a historically constituted rationality to adapt and innovate with changing times. This may hold cues for a sustainable future of Thar.

Abstract
Background
The efficacy of high flow nasal canula oxygen therapy (HFNO) to prevent invasive mechanical ventilation (IMV) is not well established in severe coronavirus disease 2019 (COVID-19). The aim of this study was to compare the risk of IMV between two strategies of oxygenation (conventional oxygenation and HFNO) in critically ill COVID 19 patients.

Methods
This was a bicenter retrospective study which took place in two intensive care units (ICU) of tertiary hospitals in the Paris region from March 11, to May 3, 2020. We enrolled consecutive patients hospitalized for COVID-19 and acute respiratory failure (ARF) who did not receive IMV at ICU admission. The primary outcome was the rate of IMV after ICU admission. Secondary outcomes were death at day 28 and day 60, length of ICU stay and ventilator-free days at day 28. Data from the HFNO group were compared with those from the standard oxygen therapy (SOT) group using weighted propensity score.

Results
Among 138 patients who met the inclusion criteria, 62 (45%) were treated with SOT alone, and 76 (55%) with HFNO. In HFNO group, 39/76 (51%) patients received IMV and 46/62 (74%) in SOT group (OR 0.37 [95% CI, 0.18–0.76] p = 0.007). After weighted propensity score, HFNO was still associated with a lower rate of IMV (OR 0.31 [95% CI, 0.14–0.66] p = 0.002). Length of ICU stay and mortality at day 28 and day 60 did not significantly differ between HFNO and SOT groups after weighted propensity score. Ventilator-free days at days 28 was higher in HNFO group (21 days vs 10 days, p = 0.005). In the HFNO group, predictive factors associated with IMV were SAPS2 score (OR 1.13 [95%CI, 1.06–1.20] p = 0.0002) and ROX index > 4.88 (OR 0.23 [95%CI, 0.008–0.64] p = 0.006).

Conclusions
High flow nasal canula oxygen for ARF due to COVID-19 is associated with a lower rate of invasive mechanical ventilation.

AbstractIn this paper, we introduce the functional equations$$\begin{aligned} f(2x-y)+f(x+2y)&=5\bigl[f(x)+f(y)\bigr], \\ f(2x-y)+f(x+2y)&=5f(x)+4f(y)+f(-y), \\ f(2x-y)+f(x+2y)&=5f(x)+f(2y)+f(-y), \\ f(2x-y)+f(x+2y)&=4\bigl[f(x)+f(y)\bigr]+\bigl[f(-x)+f(-y)\bigr]. \end{aligned}$$f(2x−y)+f(x+2y)=5[f(x)+f(y)],f(2x−y)+f(x+2y)=5f(x)+4f(y)+f(−y),f(2x−y)+f(x+2y)=5f(x)+f(2y)+f(−y),f(2x−y)+f(x+2y)=4[f(x)+f(y)]+[f(−x)+f(−y)].We show that these functional equations are quadratic and apply them to characterization of inner product spaces. We also investigate the stability problem on restricted domains. These results are applied to study the asymptotic behaviors of these quadratic functions in completeβ-normed spaces.
On the effect of postponing pregnancy in a Zika transmission model
Authors: Soewono Edy , Lahodny Glenn 
Published: February 2021

AbstractWe construct a Zika transmission model to investigate the effect of postponing pregnancy on the infection intensity. We perform analytical and numerical investigations for deterministic and stochastic analysis to obtain the basic reproductive ratio, endemic state, probability of disease extinction, and the probability of outbreak. The results indicate that by reducing the pregnancy rate the mosquito-to-human ratio increases, and, consequently, the basic reproductive ratio increases. Simultaneously, the probability of disease extinction decreases, and the probability of disease outbreak increases. On the other hand, the endemic state of infected infants initially increases with the decrease of the pregnancy recruitment rate, up to a certain level, and decreases as the recruitment rate of pregnancy tends to zero. This work highlights that postponing pregnancy that gives the individual temporary protection for unexpected infected newborns may increase the population infectivity.

Published: February 2021

AbstractThe Hirota bilinear method is employed for searching the localized waves, lump–solitons, and solutions between lumps and rogue waves for the fractional generalized Calogero–Bogoyavlensky–Schiff–Bogoyavlensky–Konopelchenko (CBS-BK) equation. We probe three cases including lump (combination of two positive functions as polynomial), lump–kink (combination of two positive functions as polynomial and exponential function) called the interaction between a lump and one line soliton, and lump–soliton (combination of two positive functions as polynomial and hyperbolic cos function) called the interaction between a lump and two-line solitons. At the critical point, the second-order derivative and the Hessian matrix for only one point will be investigated and the lump solution has one maximum value. The moving path of the lump solution and also the moving velocity and the maximum amplitude will be obtained. The graphs for various fractional ordersαare plotted to obtain 3D plot, contour plot, density plot, and 2D plot. The physical phenomena of this obtained lump and its interaction soliton solutions are analyzed and presented in figures by selecting the suitable values. That will be extensively used to report many attractive physical phenomena in the fields of fluid dynamics, classical mechanics, physics, and so on.

An adequate definition of α-mild solutions is obtained and the existence, uniqueness and continuous dependence of α-mild solutions for the presented control system are also established. The existence of optimal pairs of nonlocal fractional evolution systems is also demonstrated with a view on the construction of the Lagrange problem. Finally, an example is propounded for the presentation of optimal control.
Variability in daily or weekly working hours and self-reported mental health problems in Korea, Korean working condition survey, 2017
Authors: Lee Hye-Eun , Kim Myoung-Hee , Choi Min , Kim Hyoung-Ryoul , Kawachi Ichiro 
Published: February 2021

Abstract
Background
Working hour regulation in Korea is being revised to allow increasing variability in number of working hours. We sought to investigate the association between variability in the number of daily or weekly working hours with or without long working hours (> 52 h/w) and mental health among South Korean workers.

Methods
We used data from 28,345 full-time, non-shift employed workers working more than 30 h per week participating in the Korean Working Condition Survey in 2017. We defined six groups according to variability in daily or weekly working hours (same number vs different number) and weekly working hours (31–40, 41–52, > 52 h per week). Odds ratios (ORs) and confidence intervals (CIs) for self-reported depressive symptoms and anxiety were calculated using workers with same number of working hours/31–40 h per week as the reference.

Results
Variability in number of work hours every day or week combined with > 52 working hours per week showed the highest risk of depressive symptoms (OR = 5.13, 95% CI 3.25–8.11) and anxiety (OR = 3.75, 95% CI 2.39–5.88) compared to the reference group, controlling for age, sex, education, occupation, industry, salary, workers’ choice of working hours and overtime payment. Workers working ≤52 h/w were adversely impacted by variable working hours as well.

Conclusions
Variable daily or weekly working hours were associated with poorer self-reported depressive and anxiety symptoms in Korea, among full-time and non-shift workers. Reform of the Korean Labor Standards Act warrants consideration.
Facilitators and barriers in anorexia nervosa treatment initiation: a qualitative study on the perspectives of patients, carers and professionals

Published: February 2021

Abstract
Background
An early psychotherapeutic treatment of anorexia nervosa (AN) is crucial for a good prognosis. In order to improve treatment initiation, knowledge about facilitators and barriers to treatment is needed.

Objective
Against this background, we aimed to identify facilitators and barriers from the perspectives of patients, carers and professionals using a qualitative approach.

Method
To this end, semi-structured interviews were conducted in triads of female patients with AN aged 14 years and older at the beginning of their first psychotherapeutic treatment, their carers, and referring health care professionals. A modified Grounded Theory approach was used for analysis.

Results
In total, 22 interviews were conducted (n = 6 adults, n = 4 adolescents, 4 full triads). The duration of untreated AN ranged between 30 days and 25.85 years (M = 3.06 ± 8.01 years). A wide spectrum of facilitators and barriers within the patient, the social environment, the health care system and the society were identified. Most prominent factors were ‘recognizing and addressing’ by close others, ‘waiting times and availability’ and ‘recommendations and referrals’ by health care professionals. ‘Positive role models for treatment’ were perceived as a specific facilitative social influence. Facilitators were more frequently mentioned than barriers and most of the factors seem to hold potential for modifiability.

Conclusion
Overall, the findings suggest that early intervention approaches for AN should not only address patients and the health care system, but may also involve carers and successfully treated former patients.

Persistence and course of mental health problems from childhood into adolescence: results of a 10-year longitudinal study
Authors: Supke Max , Ferling Caterina , Hahlweg Kurt , Schulz Wolfgang 
Published: February 2021

Abstract
Background
Mental health problems (MHP) in children and adolescents (CA) are common. This longitudinal study analyzed the prevalence, course, and persistence of MHP over 10 years from childhood into adolescence based on a sample from the Future Family project (N = 230).

Methods
At the pre-assessment point the children were on average 5 (SE = 1) and the mothers 35 (SE = 5) years old. Descriptive methods, Chi2-tests, binary logistic regression, and different analytical approaches (number chains, transition probability) were used.

Results
Approximately 24% of the CA suffered from borderline clinical or clinically relevant MHP. The largest proportion of the sample was stable healthy (70%), whereas 15% of the CA showed chronic mentally ill, 8% transient, 4% negative and 4% positive courses. The mental health of the mother proved to be a decisive predictor for chronic mentally ill courses. Short-term persistence rates ranged between 60 and 70% from one assessment point to the next one. On the other hand, long-term persistence rates (from childhood into adolescence) were lower (51–59%).

Conclusion
One in seven children in this sample suffered from chronic MHP, while only one third of the CA in Germany with clinically relevant MHP take advantage of psychological or psychiatric care. Prevention programs should be considered as an effective and economic approach to reduce childhood suffering in Germany.
Classroom, media and church: explaining the achievement differences in civic knowledge in the bilingual school system of Estonia
Authors: Põder Kaire , Lauri Triin 
Published: February 2021

AbstractThis study investigates civic and citizenship education in a unique post-Communist context–in the bilingual education system of Estonia. Estonia continues to have a bilingual school system where there are Estonian and Russian language schools in parallel. While Estonian language school students are ranked very high in international comparisons, there is a significant difference between the achievement of Estonian and Russian language school students. We claim that this minority achievement gap in the performance of civic and citizenship knowledge is in addition to family background characteristics explained by behavioral and attitudinal factors that are moderated by the school language. Behavioral and attitudinal independent variables that we consider relevant in our analysis are classroom climate, trust in various media channels, and students’ beliefs in the influence of religion. We rely on hierarchical modeling to capture the embedded data and aim to explain how the different layers (school- and student level) interact and impact civic knowledge. We show that an open classroom is beneficial to students and part of the gap can be explained by Russian school students’ lower involvement in such practices. The strength of the belief in the influence of religion, on the contrary, is hurting students, despite that the negative effect is smaller for minority students there is a higher aggregate negative effect of it and therefore it also contributes to the minority achievement gap. Media trust indicators explain the gap marginally while the high trust of social media hurts students’ civic knowledge scores–still more Russian school students trust social media more than Estonian school students.

Published: February 2021

AbstractThe widespread influence of social media impacts every aspect of life, including the healthcare sector. Although medics and health professionals are the final decision makers, the advice and recommendations obtained from fellow patients are significant. In this context, the present paper explores the topics of discussion posted by breast cancer patients and survivors on online forums. The study examines an online forum, Breastcancer.org, maps the discussion entries to several topics, and proposes a machine learning model based on a classification algorithm to characterize the topics. To explore the topics of breast cancer patients and survivors, approximately 1000 posts are selected and manually labeled with annotations. In contrast, millions of posts are available to build the labels. A semi-supervised learning technique is used to build the labels for the unlabeled data; hence, the large data are classified using a deep learning algorithm. The deep learning algorithm BiLSTM with BERT word embedding technique provided a better f1-score of 79.5%. This method is able to classify the following topics: medication reviews, clinician knowledge, various treatment options, seeking and providing support, diagnostic procedures, financial issues and implications for everyday life. What matters the most for the patients is coping with everyday living as well as seeking and providing emotional and informational support. The approach and findings show the potential of studying social media to provide insight into patients' experiences with cancer like critical health problems.
CircCTNNA1 acts as a ceRNA for miR-363-3p to facilitate the progression of colorectal cancer by promoting CXCL5 expression
Authors: Zhang Yan , Zheng Sheng , Liao Nansheng , Huang Huifeng , Chen Wenxiao , Wu Zhenxing , Wu Deqing 
Published: February 2021

Abstract
Background
Circular RNAs (circRNA) have been shown to be involved in the pathogenesis of colorectal cancer (CRC). CircCTNNA1 was found to be one of the upregulated circRNAs in CRC. However, there are few studies on circCTNNA1, so it is necessary to carry out further studies.

Methods
The expression of circCTNNA1, microRNA (miR)-363-3p, and chemokine C-X-C motif ligand 5 (CXCL5) was detected by quantitative real-time PCR (qRT-PCR). The protein levels of CXCL5 and metastasis markers were measured using western blot (WB) analysis. Cell proliferation, apoptosis, cell cycle, migration, and invasion were determined by cell counting kit 8 (CCK8) assay, colony formation assay, flow cytometry, and transwell assay. The relationship between miR-363-3p and circCTNNA1 or CXCL5 was evaluated via dual-luciferase reporter assay and RNA immunoprecipitation assay. Animal study was performed to explore the function of circCTNNA1 on CRC tumorigenesis.

Results
CircCTNNA1 and CXCL5 were highly expressed in CRC. Knockdown of circCTNNA1 could inhibit the proliferation, cell cycle, metastasis, and promote the apoptosis of CRC cells. MiR-363-3p could be sponged by circCTNNA1, and the inhibition effect of circCTNNA1 silencing on CRC progression could be reversed by miR-363-3p inhibitor. Moreover, miR-363-3p could interact with CXCL5, and CXCL5 overexpression also could reverse the suppressive effect of miR-363-3p on CRC progression. Downregulation of circCTNNA1 also could hinder the tumor growth of CRC in vivo.

Conclusion
CircCTNNA1 enhanced CRC progression via regulating the miR-363-3p/CXCL5 axis.
Adaptation of the barriers to help-seeking for trauma (BHS-TR) scale: a cross-cultural cognitive interview study with female intimate partner violence survivors in Iceland

Published: February 2021

Abstract
Background
Even though traumatization is linked to substantially reduced health-related quality of life, help-seeking and service utilization among trauma survivors are very low. To date, there has not been available in Iceland a culturally attuned, self-reported measure on help-seeking barriers after trauma. This study aimed to translate and cross-culturally adapt the English version of Barriers to Help-Seeking for Trauma (BHS-TR) scale into the Icelandic language and context.

Methods
The BHS-TR was culturally adapted following well-established and rigorous guidelines, including forward-backward translation, expert committee review, and pretesting through cognitive interviews. Two rounds of interviews with 17 female survivors of intimate partner violence were conducted using a think-aloud technique and verbal probing. Data were analyzed using qualitative content analysis, a combination of deductive and inductive approaches.

Results
Issues with the BHS-TR that were uncovered in the study were classified into four categories related to general design, translation, cultural aspects, and post-trauma context. The trauma-specific issues emerged as a new category identified in this study and included concepts specific to trauma experiences. Therefore, modifications were of great importance—resulting in the scale becoming more trauma-informed. Revisions made to address identified issues improved the scale, and the process led to an Icelandic version, which appears to be semantically and conceptually equivalent to the original version; additionally, the results provided evidence of content validity.

Conclusions
As a cognitive interview study, it adds to the growing cognitive interviewing methodology literature. Furthermore, the results provide essential insights into the self-report response process of trauma survivors, highlighting the significance of making health-related research instruments trauma-informed.
