Abstract
PurposeMyocardial flow reserve (MFR) derived from 13N-ammonia positron emission tomography (NH3-PET) can predict the prognosis of patients with various heart diseases. Coronary computed tomography angiography (CCTA) is a non-invasive investigation for ischemic heart disease. The coronary artery disease reporting and data system (CAD-RADS) was established to standardize and facilitate the reporting of CCTA data regarding CAD. This study aimed to investigate the prognostic value of CAD-RADS and MFR.MethodsA total of 133 patients who underwent NH3-PET and CCTA within 3 months were enrolled. Patients were divided into groups with CAD-RADS 0-2 and ≥3 and into groups with MFR ≥2.0 and <2.0. The endpoint was major adverse cardiac events (MACE) comprising all-cause death, acute coronary syndrome, hospitalization due to heart failure, and cerebrovascular disease. The ability of CAD-RADS and MFR to predict MACE was analyzed using Kaplan-Meier analysis.ResultsThere was no significant difference in MFR between patients with CAD-RADS 0-2 and ≥3 (2.3±0.9 vs. 2.2±0.7, p=0.50). The MACE rate for patients with CAD-RADS 0-2 and ≥3 was equivalent (log-rank test, p=0.64). Patients with MFR <2.0 had a significantly higher MACE rate than those with MFR ≥2.0 (p=0.017). In patients with CAD-RADS ≥3, patients with MFR <2.0 had a significantly higher MACE rate than those with MFR ≥2.0 (p=0.034).ConclusionCAD-RADS did not contribute to MACE prediction. Conversely, MFR was useful in predicting MACE, allowing for further risk stratification in addition to CAD-RADS.

Abstract
Purpose: The role of soil biotic and abiotic factors in crucial ecosystem services such as primary production, organic matter dynamics, nutrient cycling, and soil biota community structure in the Araucaria ecosystem remains poorly quantified. We aimed to understand how the site quality affects the development of organic horizons, root growth, soil chemical properties, and the entire soil biota community in even aged and monospecific Araucaria angustifolia plantations. Methods: We collected soil monoliths to describe layers of organic matter and the complex soil food web into these layers. We determined soil pH, soil moisture, total nitrogen, available P, and total organic carbon into each layer (litter, F-layer, H-layer, and A horizon), the biomass of fine roots, the community structure of soil biota, arbuscular mycorrhizal fungi, and nematodes, as well as the microbial biomass carbon. Results: In the high-quality site, there was significantly higher organic matter formation, nutrient cycling (N and P), root growth, soil moisture, soil biota diversity, arbuscular mycorrhizal fungi, nematodes, and microbial activity evaluated by the microbial biomass carbon compared to the low-quality site. Conclusions: High-quality sites promote the development of organic horizons, root growth on superficial layers that provide plant nutrient release, the A horizon nutrient contents, and the entire soil biota community in monospecific Araucaria angustifolia plantations located on humid subtropical Cambisols. This creates a positive plant-soil feedback that maintains soil quality and increases primary production, nutrient cycling, and habitat and food for the soil food web.

Published: May 2021

Abstract
In this work, interlayers with different thickness were used to weld A6061 aluminum alloy and SUS 821L1 duplex stainless steel. The results indicated that the interlayer thickness had a significant effect on the welding. The influence of the air shock wave between the plates on the welding results was examined. The fluid-Solid coupling finite element method was used to simulate the movement of the interlayer under the action of the air shock wave. The smoothed particle hydrodynamics method was used to simulate the oblique impact process of the plates, and the unwelded samples were analyzed using the simulation results. In the analysis of weldability window, the influence of the interlayer on the upper and lower limits was examined.

Abstract
Background: To retrospectively investigate the grey-scale, Doppler, contrast-enhanced and microvascular ultrasound of five patients with primary testicular lymphoma of our institute through review literature analysis.Methods: From January to November 2020, five patients with primary testicular lymphoma confirmed by histology were preoperatively investigated with a standardized sonographic protocol including contrast-enhanced and microvascular ultrasound.Results: Conventional ultrasound showed localized hypoechogenicity represented with solitary lesions(2 of 5), multiple lesions (2 of 5), or entire testicular involvement (1 of 5). And increased blood flow appeared by color Doppler ultrasound with straight vascular sign(4 of 5). In contrast-enhanced ultrasound images confirmed this pattern(4 of 5) and presented incresaed enhancement with enlarged range. On microvascular ultrasound imagings, all lesions were presented with straight and parallel course of intralesional vessels(5 of 5).Conclusions: Here, we identified the increased vascularity with enlarged range on contrast-enhanced ultrasound along with a linear nonbranching pattern by vascular sign on microvascular ultrasonographic of testicular lymphoma.

Published: May 2021

Abstract
Background: Teen pregnancy prevention in the United States has traditionally focused on the development, testing, and subsequent implementation of a set of evidence-based programs (EBPs), recommended nationally. However, these existing EBPs often do not prioritize the most at-risk or vulnerable populations. Methods: The Innovative Teen Pregnancy Prevention Programs (iTP3) project was funded to facilitate the development of new, innovative programs to reach disparate populations. Through a mixed methods design, iTP3 evaluated the process and resulting innovative programs from five iterative cohorts of funded organizations, referred to as Innovators. iTP3 utilized both a traditional funding model with more traditional methods of capacity building assistance, but transitioned over time to a design-focused funding model in which organizations and individuals developed innovative programs through an intensive human centered design process. Results: Evaluation results showed that the resulting portfolio of programs had differences in the types of programs resulting from the differing funding models. Notable differences among programs from the two funding models include program length, along with personnel, time, and resources needed to develop and manage. Conclusion: Both traditional and design funding models led to innovative programs, with notable differences in the development process and resulting programs.
Industrial lignins: the potential for efficient removal of Cr(VI) from wastewater
Authors: Zhang Hao , Zhou Haifeng 
Published: May 2021

Abstract
Cr(VI), a serious threat to human health, widely exists in the effluents of various industrial processes.. In this paper, the potential of industrial lignin for efficient removal of Cr(VI) from wastewater were systematacially investigated, including pulping black liquor lignin (BLN), enzymolysis lignin (ELN), and SPORL pretreatment spent liquor (FS). The structure characterizations of three lignins were investigated by TG, FTIR, BET, SEM, and XPS. Among these three lignins, BLN showed the highest adsorption amount of Cr(VI) and best selectivity in wastewater simulation. According to the Langmuir model, the calculated maximum adsorption amount of Cr(VI) on ELN, BLN, and FS was 765.60, 880.57, and 721.58 mg g− 1, respectively. The adsorption of Cr(VI) by industrial lignins was a chemisorption process, during which Cr(VI) was reduced to low toxic Cr(III). This paper provided a promising application for the effective utilization of industrial lignins.

Abstract
Purpose: Preterm birth represents one of the main causes of neonatal morbimortality and a risk factor for neurodevelopmental disorders. Appropriate predictive methods for preterm birth outcome, which consequently would facilitate preventing programs, are needed. We aim to predict delivery date in women with a threatened preterm labor (TPL) based on stress response to TPL diagnosis, cumulative life stressors, and relevant obstetric variables. Methods: A prospective cohort of 157 pregnant women with TPL diagnosis between 24 and 31weeks gestation formed the study sample. To estimate the stress response to TPL, maternal salivary cortisol, α-amylase levels, along with anxiety and depression symptoms were measured. To determine cumulative life stressors, previous traumas, social support, and family functioning were registered. Then, linear regression models were used to examine the effect of potential predictors of birth date. Results: The main predictors were lower family adaptation, higher Body Mass Index (BMI), higher cortisol levels and TPL diagnosis week, which showed a non-linear interaction with cortisol levels: TPL women with middle- and high-cortisol levels before 29 weeks of gestation presented an imminent labor.Conclusion: A combination of stress response to TPL diagnosis (salivary cortisol) and cumulative stressors (family adaptation) together with obstetric factors (TPL week and BMI) was the best birth date predictor. Therefore, a psychosocial therapeutic intervention program aimed to increase family adaptation and decrease cortisol levels at TPL diagnosis as well as losing weight, may prevent preterm birth in symptomatic women.

Abstract
The main purpose of this research is to study the analysis of the screw thread machining process for micro-type circular rods. During the analysis, the SUS304 stainless steel micro-type circular rod is used to analyze the micro thread machining process for the circular rod that will be fabricated according to varied outer diameters (Ø1.9mm, Ø1.94mm and Ø2mm), varied pitches (0.25mm and 0.4mm), and specific friction factors (0.1, 0.2, 0.3, 0.5 and 0.7). Through the micro material parameters with scale factors being corrected, the finite element analysis is conducted in order to learn about the effect of pitches and friction factors on the screw threads of the micro-type circular rod during the machining process. During the research, the finite element analysis was also conducted through the use of full integration rule and by coupling the shape function, as being inferred from the 3D tetrahedral element with 4 corner nodes, in the stiffness matrix. This research focuses on the simulation of comprehensive forming resume data, stress/strain distribution and thread shape distribution relating to the thread machining process for the micro-type circular rod. In the meantime, the micro-type circular rod screw thread machining die is also designed for carrying out the micro-type thread machining experiment for the SUS304 micro-type circular rod. The outcome is also compared with the simulation result to verify the reliability of the aforesaid analysis method. During the research, the difference between traditional material parameters and that of the corrected micro dimensions is also analyzed with the result provided below: The simulation result of the corrected material parameters indicated that the maximum principal stress tends to grow along with the enlarging of the pitch, but there isn’t a visible difference between the maximum principal strain and the material parameters being used before and after the modification. When the friction factors are changing during the micro-type circular rod screw thread machining process, its torsional, stress, and strain force tends to grow along with the increase of friction factors.

Published: May 2021

Abstract
This paper examines the determinants of happiness index ratings in European countries over 8 time points using unique data from the Eurostat, World Bank and World Happiness Reports. To examine the determinants of happiness index ratings for EU-27 countries over the 2012-2019 period, panel ordinary least square (OLS) and quantile regression model are used to data obtained from all sample. Evidence from European data on happiness index generate some important key outcomes; economic outcomes levels with both current taxes and inflation rate have a positively relationship on happiness index ratings (HIR), while total employment rate has a significant negatively on HIR. Additionally, in a quantile panel regression of 27 countries, the impact of financial inclusion on happiness index looks to change with a country’s level of income. On the macroeconomic level, gross domestic product (GDP) improves the happiness index for the individual under certain conditions. Thus, GDP on 0.25th quantile levels positively significant impacts the HIR for leader countries. Overall, empirical evidence suggests that macro-economic variables and the labor market proxies of the countries play a key role in determining happiness index ratings as well.

Abstract
Purpose To report dislocation of the lens or intraocular lens (IOL) caused by family violence, a social problem that is increasing worldwide. Methods Retrospective case series. We investigated the medical records of 43 consecutive eyes of 41 cases with lens or IOL dislocation that underwent surgery at our hospital. Of all eyes, 4 eyes of 3 cases were caused by family violence.Results Case 1. A 70-year-old female with narrow anterior chamber and high intraocular pressure in her left eye due to lens dislocation was referred to our hospital after her husband had beaten her with a fist. She explained to the previous doctor that she had hit her eye by herself.Case 2. A 99-year-old female with in-the-bag IOL dislocation in her left eye 10 years after receiving cataract surgery was referred to our hospital. The following year, she was referred to our hospital because the same incident occurred in her right eye. She explained to the previous doctor that she had fallen, but was found to be due to family violence.Case 3. A 62-year-old female suffered dislocation of an IOL inserted in her left eye 10 years previously. She also presented with a mature cataract in the right eye. While her explanation to the referring doctor was that she tumbled and fell, further inquiry revealed family violence to be the cause.Conclusion Lens dislocation may be caused by family violence despite a conflicting initial clinical history.

Abstract
Background Evidence is growing for the efficacy of platelet-rich plasma (PRP) in knee osteoarthritis (OA). Here, we investigated the effects of PRP and placebo by performing a randomized, double-blind, within-person between knees comparison of measurements.Methods Thirty patients with equal radiographic grades of OA in both knees received a single injection of PRP in one knee and normal saline as a placebo in the contralateral knee. Knee symptoms were assessed at baseline and at 6-week follow-up using the WOMAC (Western Ontario and McMaster Universities) Osteoarthritis Indices for pain, stiffness, and physical function and the pain visual analog scale (VAS) assessments.Results The VAS-pain and the mean WOMAC subscales- pain, stiffness, and function- decreased significantly (P = 0.001, 0.005, 0.024, and 0.005, respectively) from baseline to week 6 in the PRP-injected knees, while in the placebo-injected knees there were only a significant reduction of VAS and no difference in WOMAC outcomes. Intergroup comparison of pain-VAS and WOMAC sub-scales revealed no statistically significant differences between PRP- and placebo-treated knees of patients post-injection.Conclusion This study found little difference between the effects of intra-articular PRP injection and placebo when applied to the same patient. Non-significant improvement in osteoarthritis indices between the treatment and placebo-received knees indicate the need for additional clinical trials of crossover design.Trial registration: IRCT2016030626922N1

Abstract
Purpose: To determine the prevalence of keratoconus (KC) in relation to ethnicity in N. Macedonia. Methods: This was a cross-sectional, interventional retrospective study. Chart reviews were performed for all new patients attending between January 2016 and January 2020 at the Sistina Ophthalmology Hospital in Skopje. All patients were screened, KC diagnosis and classification was based on the corneal topography. Ethnicity and gender classifications were according to patients’ self-opinions. Results: A total of 2812 patients charts reviewed. The mean age was 31.71 years (SD, ±9.73), 1209 (43%) were male. 2050 (72.9%) declared themselves as Macedonians, 649 (23.1%) Albanians, 76 (2.7%) Turks and 37 (1.3%) in other ethnicities. Differences in age between the ethnic groups was statistically significant (𝑥2=90.225, p<0.001). KC was diagnosed in 343 patients (12.2%), 9 were KC suspects and 6 were pellucid marginal degeneration. KC was more frequent in males (n=246, 71.7% of total) and skewed towards younger patients. Increasing patients’ age decreased the odds of KC diagnosis by 3.7%(95% CI:1.8%-4.4%) per annum. Males were 4 times more likely to be diagnosed with KC (AOR=4.01;95% CI:3.12–5.16). In comparison with Macedonian patients, Turks were more likely to be diagnosed with KC (AOR=4.09;95%CI:2.47–6.78). There was no difference between Macedonians and Albanians (p=0.08). Conclusion: The prevalence of KC at a refractive surgery practice in N.Macedonia is much higher compared with general population and similar to the prevalence in Middle East Asia. Nationwide screening programs are needed to diagnose the disease earlier.

Abstract
Egg consumption is very high throughout the world and with it comes enormous amount of waste eggshells. To reduce and utilize these wastes, eggshell wastes were simply transformed to low- or high-purity calcium carbonate grades by washing, crushing, and drying to use as raw materials for producing highly valuable calcium phosphate products. Low-purity calcium carbonate grade was used to prepare triple superphosphate for using in fertilizer industry, whereas high-purity calcium carbonate grade was used to produce dicalcium phosphate dihydrate, monocalcium phosphate monohydrate, and tricalcium phosphate for using in mineral feed and food additive industries. All calcium phosphate samples obtained by simple, rapid, cheap, and environmentally safe method using eggshells and phosphoric acid were identified and their structural phases and impurities were determined by XRF, XRD and FTIR techniques. The methodologies described here will be useful to manage eggshells by converting them to highly valuable products, which can solve eggshell wastes problem from industries and communities. This finding supports the viewpoint of zero waste operation to produce value-added products for obtaining sustainable development, which may be selected as an alternative way for material recycling and waste management in the future.

Abstract
Energy system modelling can be used to assess the implications of different scenarios and support improved policymaking. However, access to data is often a barrier to starting energy system modelling in developing countries, thereby causing delays. Therefore, this article provides data that can be used to create a simple zero order energy system model for Algeria, which can act as a starting point for further model development and scenario analysis. The data are collected entirely from publicly available and accessible sources, including the websites and databases of international organizations, journal articles, and existing modelling studies. This means that the dataset can be easily updated based on the latest available information or more detailed and accurate local data. These data were also used to calibrate a simple energy system model using the Open Source Energy Modelling System (OSeMOSYS) and two stylized scenarios (Fossil Future and Least Cost) for 2020–2050. The assumptions used and results of these scenarios are presented in the appendix as an illustrative example of what can be done with these data. This simple model can be adapted and further developed by in-country analysts and academics, providing a platform for future work.
