Abstract
Background
Anaplasma, Babesia and Theileria are tick-borne pathogens (TBPs) that affect livestock worldwide. However, information on these pathogens in yaks (Bos grunniens) and Tibetan sheep (Ovis aries) on the Qinghai-Tibet Plateau (QTP), China, is limited. In this study, Anaplasma spp., Babesia spp. and Theileria spp. infections were assessed in yaks and Tibetan sheep from Qinghai Province.

Methods
A total of 734 blood samples were collected from 425 yaks and 309 Tibetan sheep at nine sampling sites. Standard or nested polymerase chain reaction was employed to screen all the blood samples using species- or genus-specific primers.

Results
The results showed that 14.1% (60/425) of yaks and 79.9% (247/309) of Tibetan sheep were infected with at least one pathogen. Anaplasma ovis, Anaplasma bovis, Anaplasma capra, Anaplasma phagocytophilum, Babesia bovis and Theileria spp. were detected in this study, with total infection rates for all the assessed animals of 22.1% (162/734), 16.3% (120/734), 23.6% (173/734), 8.2% (60/734), 2.7% (20/734) and 19.3% (142/734), respectively. For yaks, the infection rate of A. bovis was 6.4% (27/425), that of B. bovis was 4.7% (20/425) and that of Theileria spp. was 3.3% (14/425). Moreover, 52.4% (162/309) of the Tibetan sheep samples were infected with A. ovis, 30.1% (93/309) with A. bovis, 56.0% (173/309) with A. capra, 19.4% (60/309) with A. phagocytophilum and 41.4% (128/309) with Theileria spp.

Conclusions
This study revealed the prevalence of Anaplasma spp., Babesia spp. and Theileria spp. in yaks and Tibetan sheep in Qinghai Province, China, and provides new data for a better understanding of the epidemiology of TBPs in these animals in this area of the QTP, China.

AbstractBackgroundSpatial and temporal changes in the dengue incidence are associated with multiple factors, such as climate, immunity among a population against dengue viruses (DENV), circulating DENV serotypes and vertical transmission (VT) of DENV in an area at a given time. The level of VT in a specific location has epidemiological implications in terms of viral maintenance in vectors. Identification of the circulating DENV serotypes in both patients andAedesmosquito larvae in an area may be useful for the early detection of outbreaks. We report here the results of a prospective descriptive study that was conducted to detect the levels of VT inAedesmosquito larvae and circulating DENV serotypes in patients andAedesmosquito larvae from December 2015 to March 2017 in an area of Sri Lanka at high risk for dengue.MethodsA total of 200 patients with clinically suspected dengue who had been admitted to a tertiary care hospital during a dengue outbreak (3 study periods: December 2015–January 2016, June–August 2016, December 2016–January 2017) and in the inter-outbreak periods (February–May 2016 and September–November 2016) were investigated. Blood samples were drawn from the study participants to test for DENV. The houses of the study participants were visited within 7 days of admission to the hospital, andAedeslarvae were also collected within a radius of 400 m from the houses. The larvae were separately identified to species and then pooled according to each patient’s identification number. Patients’ sera and theAedeslarvae were tested to identify the infecting DENV serotypes using a reverse transcription PCR (RT-PCR) method. Levels of VT inAedesmosquito larvae were also identified.ResultsAll four DENV serotypes (DENV-1 to -4) were identified in the study area. In the early part of the study (December 2015–February 2016), DENV-3 was predominant and from April 2016 to March 2017, DENV-2 became the most predominant type. Four cases of DENV co-infections were noted during the study period in patients. Interestingly, all four DENV serotypes were detected inAedes albopictuslarvae, which was the prominent immature vectorial form identified throughout the study period in the area, showing 9.8% VT of DENV. With the exception of DENV-4, the other three DENV serotypes were identified inAedes aegyptilarvae with a VT of 8.1%.ConclusionComparatively high rates of VT of DENV was detected inAe. albopictusandAe. aegyptilarvae. A shift in the predominant DENV serotype with simultaneous circulation of all four DENV serotypes was identified in the study area from December 2015 to March 2017.Graphical Abstract

Published: December 2021

Abstract
Purpose
To study the effectiveness of diabetic yoga protocol (DYP) against management of cardiovascular risk profile in a high-risk community for diabetes, from Chandigarh, India.

Methods
The study was a randomized controlled trial, conducted as a sub study of the Pan India trial Niyantrita Madhumeha Bharath (NMB). The cohort was identified through the Indian Diabetes Risk Scoring (IDRS) (≥ 60) and a total of 184 individuals were randomized into intervention (n = 91) and control groups (n = 93). The DYP group underwent the specific DYP training whereas the control group followed their daily regimen. The study outcomes included changes in glycemic and lipid profile. Analysis was done under intent-to-treat principle.

Results
The 3 months DYP practice showed diverse results showing glycemic and lipid profile of the high risk individuals. Three months of DYP intervention was found to significantly reduce the levels of post-prandial glucose levels (p = 0.035) and LDL-c levels (p = 0.014) and waist circumference (P = 0.001).

Conclusion
The findings indicate that the DYP intervention could improve the metabolic status of the high-diabetes-risk individuals with respect to their glucose tolerance and lipid levels, partially explained by the reduction in abdominal obesity. The study highlights the potential role of yoga intervention in real time improvement of cardiovascular profile in a high diabetes risk cohort.

Published: December 2021

Abstract
Objective
Most epidemiological studies on suicidal behavior have been focused on high-income country settings. This study examine factors associated with suicidal behaviors among school-attending adolescents in three island nations. In this secondary analysis of the publicly available 2015 nationally representative GSHS data, we tested demographic, social, and behavioral attributes using multivariable logistic regression to association with suicide attempts.

Results
Within the recall period, 13.6% of participants reported having attempted suicide one or more times in the Cook Islands, 10.8% in Curaçao, and 9.8% in East Timor. In the Cook Islands, suicide ideation (AOR = 19.42, 95% CI = 9.11–41.41), anxiety (AOR = 2.51, 95% CI = 1.08–5.82), physical bullying (AOR = 3.3, 95% CI = 1.10–9.91), and cigarette smoking (AOR = 3.82, 95% CI = 1.38–10.54) were associated with suicide attempts. For Curaçaoo, suicide ideation (AOR = 7.88, 95% CI = 5.20–11.95) and suicide planning (AOR = 7.01, 95% CI = 4.24–11.60) were statistically significant. While for East Timor, suicide ideation (AOR = 4.59, 95% CI = 2.14–9.88), suicide planning (AOR = 3.36, 95% CI = 1.76–6.29), bullying victimization (AOR = 2.69, 95% CI = 1.02–7.12), and serious injuries (AOR = 2.22, 95% CI = 1.31–3.74) were statistically significant. Suicide attempt is relatively common in each of the three island nations. The socioeconomic context of adolescents might play a significant role in moderating suicidal behavior. Therefore, prevention efforts should be grounded in view of geographic, demographic, and socioeconomic contexts of the populations at risk.

AbstractThis study introduces extended Branciari quasi-b-distance spaces, a novel implicit contractive condition in the underlying space, and basic fixed-point results, a weak well-posed property, a weak limit shadowing property and generalized Ulam–Hyers stability. The given notions and results are exemplified by suitable models. We apply these results to obtain a sufficient condition ensuring the existence of a unique positive-definite solution of a nonlinear matrix equation (NME) $\mathcal{X}=\mathcal{Q} + \sum_{i=1}^{k}\mathcal{A}_{i}^{*} \mathcal{G(X)}\mathcal{A}_{i}$

Authors: Mekonnen Wubegzier , Feleke Yeweyenhareg , Asnake Wubetsh , Desalegn Yakob , Haidar Jemal , Lambisso Biruk , Zewdie Tewabech 
Published: December 2021

Abstract
Background
Adult vitamin D deficiency, which is a public health problem in low-income countries, is correlated with increased mortality. Although health care workers (HCWs) in Ethiopia are educated on important minerals their counseling on the uses of vitamin D and its possible sources was not witnessed since their knowledge and practice is low. The main aim of this study is to explore barriers to good knowledge, positive attitude, and practice of health care providers on adult vitamin D.

Methods
An exploratory qualitative study is done in three ecologies covering highland, midland, and lowland. The size of 27 participants was fixed by saturation of ideas. In-depth interviews were conducted among leaders and HCWs of different professional groups in health centers and hospitals. Moderators were Ph.D. holders. An interview guide was developed after reviewing research that was translated into the local language. Interviews were audio-taped, transcribed and, translated. Open Code software was used to code and categorize the data. Themes were developed using thematic analysis which is presented using themes and sub-themes.

Result
The main barriers are related to health systems, HCWs’ understandings, and the educational system. Lack of attention by the health systems’ leadership, missing adult vitamin D as a priority in health programs, lack of capacity building scheme and the absence of adult vitamin D management and treatment guidelines are barriers related to the health system. On the other hand, health care professionals believed that the prevalence of adult vitamin D deficiency is insignificant and vitamin D deficiency is only an issue related to children. Besides, the absence of studies,the focus of the medical curriculum on child vitamin D and the inadequacy of laboratory investigation are barriers related to the education system and research.

Conclusion
Adult vitamin D deficiency is a neglected public health problem with many barriers related to diagnosis and treatment. Barriers are related to the professionals themselves, their leadership, health facilities, and the education system. The government should give attention to adult vitamin D management and treatment, continuous on the job training, development of guidelines, purchase of laboratory equipment, the inclusion of adult vitamin D in pre-service and, in-service training curriculums.
Effects of Japanese-style online hemodiafiltration on survival and cardiovascular events
Authors: Okada Kazuyoshi , Michiwaki Hiroyuki , Tashiro Manabu , Inoue Tomoko , Shima Hisato , Minakuchi Jun , Kawashima Shu 
Published: December 2021

Abstract
Background
All-cause mortality can be reduced in patients receiving European-style high-volume post-dilution online hemodiafiltration (post-OHDF) compared with hemodialysis (HD). Japanese-style high-volume pre-dilution online hemodiafiltration (pre-OHDF) can also decrease all-cause mortality. No studies have investigated survival in patients receiving Japanese-style post-OHDF, and directly compared survival between pre-OHDF and post-OHDF. This study sought to clarify these issues.

Methods
We conducted this retrospective observational study at multiple facilities of our medical corporation, which have similar quality of healthcare management, from July 1, 2017 to July 1, 2020. Japanese-style OHDF included pre-OHDF and post-OHDF. Pre-OHDF and post-OHDF were each divided into high-volume and low-volume subgroups. We compared 3-year all-cause mortality and cardiovascular events between OHDF and high-flux HD using propensity score matching. In addition, we examined the effects of different modalities through comparisons between high-volume and low-volume pre-OHDF and between pre-OHDF and post-OHDF.

Results
Post-OHDF was associated with significantly lower all-cause mortality (P = 0.004, log-rank test; hazard ratio [HR] 0.257, 95% confidence interval [CI] 0.094–0.701) and cardiovascular events during all 3 years (P < 0.05) compared with HD. High-volume post-OHDF was associated with lower all-cause mortality compared with hemodialysis (log-rank test P = 0.022) but low-volume post-OHDF was not. Pre-OHDF was also associated with lower all-cause mortality (P < 0.001, log-rank test; HR 0.316; 95% CI 0.212–0.472) compared with HD but was not associated with cardiovascular events. All-cause mortality did not significantly differ between post-OHDF and pre-OHDF.

Conclusions
These findings suggest that Japanese-style post-OHDF may improve all-cause mortality to a level similar to that of pre-OHDF and that post-OHDF, particularly high-volume post-OHDF may reduce cardiovascular events.
Unification of massless field equations solutions for any spin
Authors: Hojman Sergio A. , Asenjo Felipe A. 
Published: December 2021

Abstract
A unification in terms of exact solutions for massless Klein-Gordon, Dirac, Maxwell, Rarita-Schwinger, Einstein, and bosonic and fermionic fields of any spin is presented. The method is based on writing all of the relevant dynamical fields in terms of products and derivatives of pre-potential functions, which satisfy the d'Alembert equation. The coupled equations satisfied by the pre-potentials are non-linear. Remarkably, there are particular solutions of (gradient) orthogonal pre-potentials that satisfy the usual wave equation which may be used to construct exact non-trivial solutions to Klein-Gordon, Dirac, Maxwell, Rarita-Schwinger, (linearized and full) Einstein and any spin bosonic and fermionic field equations, thus giving rise to a unification of the solutions of all massless field equations for any spin. Some solutions written in terms of orthogonal pre-potentials are presented. Relations of this method to previously developed ones, as well as to other subjects in physics are pointed out.
Bigdata-based investigation of heterogeneous migration and population distribution
Authors: Fan Z. W. , Xiong L. , Zheng B. 
Published: December 2021

Abstract
Human mobility is very important in understanding complex social and economic systems. With massive empirical datasets from the China Household Finance Survey and the National Statistics in the UK, we construct a migration probability matrix, and analyze the heterogeneous migration patterns. We then develop a random walk model to dynamically simulate the population distribution. In the stationary state, the resulting population distribution is in good agreement with the real statistical data. For comparison, simulations with an optimized gravity model and other datasets such as the census data in China are also performed. Further, the model simulation is applied to predict the demographic trend with different education levels. Our method could be generally extended to other real communities and internet worlds.
Treatment Adherence in Patients with Mental Illnesses: The Effect of Stigma and Spirituality
Authors: Taheri Leila , Shamsaei Farshid , Sadeghian Efat , Tapak Leili 
Published: December 2021

Aim of the studyTreatment nonadherence in patients with mental illnesses recurs and exacerbates the complications of the disease and disrupts the treatment process. Experienced stigma may aggravate treatment nonadherence while spiritual well-being may improve stigma and treatment adherence. This study aimed to determine the relationship of stigma with treatment adherence and spiritual well-being in patients with mental illnesses in Iran in 2019.Subject or material and methodsThis cross-sectional correlational study was performed on patients with mental illnesses who referred to Farshchian Psychiatry Hospital of Hamadan, from December 2018 to March 2019. A total of 250 available patients were selected and asked to complete demographic, stigma, treatment adherence, and spiritual well-being questionnaires under the supervision of a researcher. Data were analyzed using descriptive statistics and path analysis in SPSS22 and AMOS23.ResultsMean stigma, treatment adherence, and spiritual well-being scores were calculated as 2.2±0.5, 139.89±27.52, and 83.12±19.5, respectively. The results showed a significant negative correlation between stigma and treatment adherence (r=-0.54, P<0.001). In addition, there was a significant direct relationship between treatment adherence and spiritual well-being (r=0.44, P<0.001) and a significant negative relationship between stigma and spiritual well-being (r=-0.48, P<0.001)DiscussionThe results showed a relationship between stigma and treatment adherence, stigma and spiritual well-being, and spiritual well-being and treatment adherence.ConclusionsThen can be suggested that treatment teams can improve treatment adherence by undertaking several interventions to reduce stigma and promote spiritual well-being to prevent the adverse individual and social effects of treatment nonadherence
Distributionally Robust Optimization Under a Decision-Dependent Ambiguity Set with Applications to Machine Scheduling and Humanitarian Logistics
Authors: Noyan Nilay , Rudolf Gábor , Lejeune Miguel 
Published: December 2021

We introduce a new class of distributionally robust optimization problems under decision-dependent ambiguity sets. In particular, as our ambiguity sets, we consider balls centered on a decision-dependent probability distribution. The balls are based on a class of earth mover’s distances that includes both the total variation distance and the Wasserstein metrics. We discuss the main computational challenges in solving the problems of interest and provide an overview of various settings leading to tractable formulations. Some of the arising side results, such as the mathematical programming expressions for robustified risk measures in a discrete space, are also of independent interest. Finally, we rely on state-of-the-art modeling techniques from machine scheduling and humanitarian logistics to arrive at potentially practical applications, and present a numerical study for a novel risk-averse scheduling problem with controllable processing times. Summary of Contribution: In this study, we introduce a new class of optimization problems that simultaneously address distributional and decision-dependent uncertainty. We present a unified modeling framework along with a discussion on possible ways to specify the key model components, and discuss the main computational challenges in solving the complex problems of interest. Special care has been devoted to identifying the settings and problem classes where these challenges can be mitigated. In particular, we provide model reformulation results, including mathematical programming expressions for robustified risk measures, and describe how these results can be utilized to obtain tractable formulations for specific applied problems from the fields of humanitarian logistics and machine scheduling. Toward demonstrating the value of the modeling approach and investigating the performance of the proposed mixed-integer linear programming formulations, we conduct a computational study on a novel risk-averse machine scheduling problem with controllable processing times. We derive insights regarding the decision-making impact of our modeling approach and key parameter choices.
Durable Goods Adoption and the Consumer Discount Factor: A Case Study of the Norwegian Book Market
Authors: Daljord Øystein 
Published: December 2021

We exploit a change in Norway’s fixed book pricing policies to construct exclusion restrictions with which to identify consumers’ discount factor. We assume that the policy change generated an unanticipated, exogenous shock to consumers’ expectations about future price cuts. Our findings suggest that consumers are much more impatient than would be implied by the real rate of interest, challenging the standard assumed rate of discounting in the extant literature on dynamic demand estimation. The high rate of consumer impatience is consistent with laboratory studies in the behavioral economics and decision-making literatures. This paper was accepted by Matthew Shum, marketing.
