Authors: Sade Shoval , Pickholtz Hodaya , Melzer Itshak , Shapiro Amir 
Published: May 2023

Abstract
Background: ‘Perturbation-based balance training’ (PBBT) is a training method that was developed to improve balance reactive responses to unexpected balance loss. This training method is more effective in reducing fall rates than traditional balance training methods. Many PBBTs are performed during standing or treadmill walking which targeted specifically step reactive responses, we however, aimed to develop and build a mechatronic system that can provide unexpected perturbation during in-place walking the Elliptical Perturbation System (the EPES system), with the aim of improving specifically the trunk and upper limbs balance reactive control.
Methods: This paper describes the development, and building of the EPES system, using a stationary Elliptical Exercise device, which allows training of trunk and upper limbs balance reactive responses in older adults.
Results: The EPES system provides 3-dimensional small, controlled, and unpredictable sudden perturbations during stationary in-place walking. We developed software that is able to identify a trainee's trunk and arms reactive balance responses using a stereo camera. After identifying an effective trunk and arms reactive balance response, the software controls the EPES system motors to return the system to its horizontal baseline position after the perturbation. The system thus provides closed-loop feedback for a person's counterbalancing trunk and arm responses, helping to implement implicit motor learning for the trainee. The pilot results show that the EPES software is able to successfully identify balance reactive responses among participants who are exposed to a sudden unexpected perturbation during in-place walking on the EPES system.
Conclusions: EPES trigger reactive balance responses involving counter-rotation action of body segments and simultaneously evoke arms, and trunk reactive response, thus reactive training effects should be expected.
Risk of Falls and Strategies to Reduce Fall Rates in Nursing Homes
Authors: Brahmbhatt Viraj 
Published: May 2023

Abstract
Falls are a serious concern among the elderly community and contribute danger through immediate harm as well as persistent risk that carries on after the fall. One in four elderly adults fall every year resulting in 32,000 annual deaths due to falls. After a fall, there may be weakness, ongoing pain, concussive symptoms, and loss of confidence. Falls are most likely to occur while attempting to stand up or sit down. Currently, there are many interventions in use to prevent falls such as alarms, restraints, hip protectors, and lowering bed height. Studies have found these interventions to be ineffective at reducing fall rates and fall injury. These measures are applicable for falls that occur while sitting or lying down and as such do not account for falls that occur while standing or while attempting to stand. International efforts using staff have shown promising results in reducing falls. This model may be applicable to the American nursing home. In this model, staff assist residents in everyday tasks and are available to help when residents need help standing up or sitting down. Currently, nursing homes are short staffed. Factors such as low wages, poor working conditions, and too many tasks per worker have been cited as contributing to low employment. Additionally, loose governmental regulations on the number of residents per nurse allow for nursing homes to be operational despite being understaffed. Prevention of falls may be best addressed through an active staff that routinely visits resident rooms and assists in walking, getting up, and sitting down. Staff should be responsible for eliminating trip hazards in patient rooms. The Biden administration announced efforts to improve nursing home conditions in early 2022. Governmental interventions in the form of mandating increased staffing and wages for nursing home staff may be effective at reducing fall rates within nursing homes.

Abstract
Background Bacterial virulence is a key factor determining the outcome of each bacterial infection and virulent bacteria are often associated to high-risk infections. Extraintestinal pathogenic Escherichia coli (ExPEC) is the most implicated bacterium in human bacterial infections and its virulence factors are classified into five categories: adhesins, toxins, iron capture systems, protectins and invasins. Furthermore, bacterial biofilms are the main cause of hospital-acquired infections like urinary catheter-associated infections, valve endocarditis, Otitis and cystic fibrosis.Results For the sixteen virulence genes sought by standard polymerase chain reaction (PCR), all the 78 ExPECs isolates carried at least four virulence genes. Following prevalences of virulence genes were reported: adhesins genes fimH (98.7%), mrkD (98.7%), papC (46.2%), afaC (9%), sfa / focDE (1.3%); iron acquisition systems genes entB (98.7%), fepA (98.7%), ybtS (93.6%), fyuA (91%), iucA (91%), iucB (91%), iutA (34.6), iroB (6.4%), iroN (6.4%) and toxins genes hlyA (10.3%), cnf (1 & 2) (10.3%). Seventy-five out of 78 isolates (96.2%) carried at least the combination of two adhesins genes and two iron capture systems genes whereas 8 out of 78 (10.3%) harbored the combination of (adhesins genes + iron acquisition systems genes + toxins genes). Among the 78 strains studied, one hospital-acquired strain isolated from urine harbored 15 virulence genes out of 16 sought. The evaluation of biofilm-formation capacity revealed that all (29/29) hospital-acquired isolates were biofilm producers with (6/29; 20.7%) strong biofilm producers, (15/29; 51.7%) moderate biofilm producers and (8/29; 27.6%) weak biofilm producers. Isolates carrying papC had greater biofilm formation capacity than those not carrying papC (p < 0.001).Conclusions Most of our strains had moderate biofilm-formation capacity and carried an average of 9 virulence genes out of 16 sought. These eight strains carrying a combination of genes (adhesins + iron acquisition systems genes + toxins genes) may be hypervirulent isolates. Additional studies may confirm this. The deepening of this kind of study on bacterial virulence and hospital bacterial biofilms could lead to the improvement of infections investigation, prevention and therapeutic protocols.

Abstract
Introduction
Excessive dietary sodium (Na) consumption is a major health care issue in the developed world and linked to many poor health outcomes. Elevated urinary Na may lead to hypercalciuria and an increase in urinary stone risk. Our study aimed to assess the impact of targeted dietary counseling, and its effect on normalizing urinary Na levels in hypercalciuric stone patients.
Methods
A retrospective analysis of a prospectively collected metabolic stone clinic database was performed. Patients with hypercalciuria and elevated urine Na on 24-hour urine collection (24-HUC) were counselled by the attending nephrologist, urologist or a registered dietician to limit their intake of dietary Na to < 2g/day in addition to receiving general dietary advice. Repeat metabolic testing was performed at least 6 months later. Logistic regression was used to determine correlations between elevated urinary Ca and Na to other urinary abnormalities and to evaluate the effect of normalizing urinary Na on other urinary parameters.
Results
Metabolic evaluations from 1184 patients were analyzed. The ninety-eight patients with concomitant hypercalciuria and hypernatriuria were predominantly male (67.3%) and had a higher median BMI than the entire cohort. The presence of elevated urinary Na was also associated with hyperuricosuria (p < 0.001) and hyperphosphaturia (p < 0.001). In follow-up, 59.4% corrected their urinary Na, and 43.8% also had their urinary Ca corrected. Patients who corrected their urinary Na were also more likely to have normal urinary values for volume (p = 0.045), oxalate (p = 0.004), and urate (p = 0.008).
Conclusions
Targeted dietary counseling can be effective in normalizing both elevated urinary Na and Ca levels in stone patients and may obviate the need for pharmacotherapy for the treatment of hypercalciuria in some patients.

Abstract
Background
Nurses' secondary traumatic stress, compassion satisfaction and posttraumatic growth are closely related, but for newly graduated nurses, there are few reports to evaluate the specific path between these three. The aim of this study was to investigate examine the mediating role of compassion satisfaction in secondary traumatic stress and posttraumatic growth among newly graduated nurses.
Methods
From March 2021 to May 2021, a total of 330 newly graduated nurses from five tertiary hospitals in China were enrolled, and asked to complete questionnaires regarding secondary traumatic stress, compassion satisfaction and posttraumatic growth. Descriptive statistics, independent-samples T-test, one-way analysis of variance (ANOVA), Pearson correlation analysis and structural equation model were used in this study. A STROBE checklist was used to report findings.
Results
The scores of secondary traumatic stress, compassion satisfaction and posttraumatic growth of newly graduated nurses were 27.11 ± 4.94, 31.89 ± 6.22 and 56.47 ± 20.41, respectively. Additionally, structural equation modeling showed that compassion satisfaction mediated the relationship between secondary traumatic stress and posttraumatic growth with the partial mediating effect of 0.089.
Conclusions
Newly graduated nurses may experience moderate secondary traumatic stress, but their posttraumatic growth is at a low level, and compassion satisfaction significantly affects the relationship between the two. Nursing managers should strengthen psychological evaluation, and promote their posttraumatic growth by improving their level of compassion satisfaction.
The urinary metabolites of volatile organic compounds and asthma in young children: NHANES 2011-2018
Authors: Xiong Yixiao , Li Tao 
Published: May 2023

Abstract
Background: Volatile organic compounds (VOCs) are synthetic chemicals that are broadly used in the production of numerous day-to-day products for residential and commercial-based applications. Evidence evaluating the prospective association between volatile organic compounds (VOCs) exposure and asthma in the U.S. children is limited. This study aimed to explore the associations between metabolites of VOCs (mVOCs) in urine, a representative of the internal exposure level of VOCs, and childhood asthma.
Methods:We conducted the cross-sectional analysis in 1559 children aged 3-12 years who participated in the National Health and Nutrition Examination Survey (NHANES) 2011-2018. In this study, we investigated the relationship between childhood asthma and urinary concentrations of five volatile organic compound metabolites, including N-Acetyl-S-(2-carboxyethyl)-L-cysteine (CEMA), N-Acetyl-S-(3-hydroxypropyl)-L-cysteine (3HPMA), N-Acetyl-S-(3-hydroxypropyl-1-methyl)-L-cysteine (HPMMA), N-Acetyl-S-(benzyl)-L-cysteine (SBMA) and 2-Methylhippuric acid (2MHA). These metabolites correspond to the parent compounds acrolein, crotonaldehyde, toluene and xylene, respectively. Adjusted logistic regression models were used to assess the relationship between mVOCs and childhood asthma, followed by a stratified analysis.
Results: Urine measurements of mVOCs were weakly associated with an increased odds of childhood asthma, including 2MHA (OR:1.1; 95% CI:0.8, 1.6), SBMA (OR:1.2; 95% CI:0.8, 1.7), CEMA (OR:1.1; 95% CI:0.6, 1.7), 3HPMA (OR:1.1; 95% CI:0.7, 1.8), and HPMMA (OR:1.2; 95% CI:0.7, 2.0). Among female children, 2MHA in urine was significantly associated with the prevalence of asthma (OR: 1.8 95% CI: 1.1, 3.1)). Gender modified associations between urinary 2MHA, but not other urinary mVOCs concentrations, and odds of childhood asthma (gender x 2MHA interaction term p-value = 0.02). Age and race/ethnicity did not modify these associations.
Conclusion: We observed some evidence that urinary mVOCs concentrations are associated with increased asthma prevalence in US children, especially urinary 2MHA is significantly associated with the prevalence of asthma in female children. Further studies are needed to fully understand the potential role of VOCs in childhood asthma

Abstract
For a wide range of people, including malnourished adults with non-communicable diseases (NCDs), micronutrient deficiency, underweight and overweight people, pregnant and lactating women, and adolescents, the current research aimed to present innovative nutraceutical formulations devoted to improving the quality of life (QoL) while promoting health. The novel nutraceutical formulations were structured on a scientific basis with evidence-based health benefits, with daily values (DVs) according to the Food and Drug Administration (FDA), containing a high-quality whey protein concentrate (WPC 70%), skim milk powder (SMP 34%), vitamins (folic acid, B12, C), minerals (iron, zinc), natural flavors (vanilla, cinnamon, coffee, chocolate), and stevia leaf extract sweetener. The novel formulations were subjected to the physicochemical, microbiological, and sensory evaluation. The results showed significant differences (P < 0.05) among formulations with natural flavors added in different amounts to provide 10 g of protein (20% DV), elemental iron and zinc, vitamin C, folic acid, and vitamin B12 (25% DV), with elemental calcium (20% DV) emerged from milk derivatives. The serving sizes of the four formulas were different according to the difference in the amount of natural flavor while keeping the same amounts of the other ingredients. Following the chocolate-flavored formulation as the first in order of overall acceptability, were coffee, cinnamon, and vanilla-flavored formulation, according to the sensory evaluation.

Published: May 2023

Abstract
Rock types are the reservoir's most essential properties and show special facies with a defined range of porosity and permeability. This study used the fuzzy c-means clustering technique to identify rock types in 280 core samples obtained from one of the wells drilled in the Asmari reservoir located in the Mansouri field. Four hydraulic flow units were determined for studied data after classifying the flow zone index with histogram analysis, normal probability analysis, and the sum of square error methods. Then the two methods of flow zone index and fuzzy c-means clustering were used to determine the rock types in given wells according to the results obtained from the implementation of these two methods in-depth, and continuity index acts, the fuzzy c-means methods with continuity number 3.12 compared to flow zone index with continuity number 2.77 shows more continuity in depth. Amounts of porosity and permeability of the different reservoir rock samples have high dispersion; the relationship between these two parameters improves by using hydraulic flow unit techniques significantly. In this study, the relationship between porosity and permeability of correlation coefficient improves and increases in each hydraulic flow unit by using the flow zone index method so that in the general case for all samples increased from 0.55 to 0.81 in the first hydraulic flow unit, 0.94 in the second hydraulic flow unit, 0.85 in the third hydraulic flow unit and 0.94 in the fourth hydraulic flow unit that this is because the samples were characterized by similar flow properties in a hydraulic flow unit. In comparison, the correlation coefficient is obtained less than the general case in the fuzzy c-means method in all hydraulic flow units.
Effect of stacking position on drying rate during radio-frequency vacuum combined with mechanical press drying of Douglas-fir and Radiata pine
Authors: Lee Changjin 
Published: May 2023

Abstract
In this study, the effect of stacking position in the chamber on the drying rate during radio-frequency vacuum combined with mechanical press (RF/VP) drying was investigated for Douglas-fir and Radiata pine. Drying test was performed at a temperature of 40°C using RF/VP dryer with approximately 3m³. The results showed that the stacking position has a significant effect on the drying rate, with a more pronounced decrease in drying rate as the number of layers increases. Moisture content (MC) on day n-1 was important factor in determining the drying rate in both species. The MC distribution of specimens in the chamber before drying was very irregular, but over time, specimens stacked on the RF charge plate side in the chamber tended to have lower MC distributions than those stacked on the ground plate side, which was serious at the layer-10. In addition, as the MC decreases below the fiber saturation point during RF/VP drying, the difference in MC according to the stacking position became more prominent. These findings provide new insights into the effect of wood dielectric properties on drying rate and are expected to improve RF/VP drying technology.

Published: May 2023

Abstract
Fuzzy dynamical modeling plays a major role in various fields, especially in biology. In our paper, we can formulate two species models with Holling type III functional response and harvesting as trapezoidal fuzzy numbers. Boundedness and positivity are found using a dynamic system. The existence of equilibrium points is existing in both crisp and fuzzy forms. Additionally, the parameters were defuzzed using a Graded Mean Value approach, and the dynamical system was reduced at various pessimistic levels. Equilibrium points and stability analysis are determined using a variational matrix in both crisp and fuzzy environments. Numerical simulations are carried out using MATLAB software.

Published: May 2023

La desvinculación entre los niveles educativos de secundaria y superior universitaria genera dificultades en el estudiantado provocando deserción estudiantil. Las asignaturas nivelatorias tienen la finalidad de reforzar las bases de conocimiento previas de las personas estudiantes, lo cual genera menor deserción y mejora el éxito académico universitario. En este trabajo, se describe la Estrategia de Nivelación en Física, Química, y Matemática (Enfiquima), con el objetivo de evaluarla desde la perspectiva estudiantil, de rendimiento académico y, mediante un análisis FODA, para la búsqueda de acciones de mejora. En esta investigación, se obtuvieron datos cuantitativos y cualitativos, por ende, es de tipo mixta, de enfoque concurrente y de diseño de triangulación concurrente. Para evaluar la Enfiquima, se trabajó con estudiantes de los tres cuatrimestres del 2021 y del primer cuatrimestre del 2022, y se realizó: a) un diagnóstico a una muestra de 286 personas estudiantes sobre su percepción con respecto a la Enfiquima y las asignaturas universitarias, b) la evaluación de la efectividad de la Enfiquima según el rendimiento académico en las asignaturas, para una población de 119 personas que cursaron, de forma previa, las asignaturas nivelatorias y c) un análisis FODA de la Enfiquima. Se determinó que el 89% (255) de las personas estudiantes encuestadas desconocían la existencia de las asignaturas niveladoras. Además, se comprobó, con datos cuantitativos, la efectividad de la Enfiquima en la asignatura de Química I; no así, en Matemáticas (por la diversidad de asignaturas según carrera cursada) y en Física I (poca población para análisis debido a requisitos solicitados en la asignatura). La mayoría del estudiantado, en Física I, Química I y Matemática, desconoce la existencia de la Enfiquima, y la mayoría de quienes cursaron nivelatoria y aprobaron la asignatura siguiente afirman que les benefició. En Química, el porcentaje de aprobación de las personas estudiantes que cursaron la nivelatoria se duplicó. Se identificaron acciones de mejora para la Enfiquima en la UNED.

El análisis de las redes académicas internacionales permite reflexionar sobre el funcionamiento de las sociedades cooperativas de profesionales de la investigación y universitarios. De ello se encarga la teoría de la diplomacia académica y la intersección entre relaciones internacionales y educación.

Mediante este enfoque teórico, y bajo la lógica de un estudio de caso que emplea un biograma, se analiza la Red de Investigación y Práctica en Liderazgo Educativo, lo cual revela los hitos más representativos de su conformación en el ámbito académico. De esta forma se encontraron no solo sus aportes, sino también sus limitaciones actuales y nuevos desafíos. Entre los resultados se puede considerar que redes académicas de investigación, educación superior, internacionalización, diplomacia son factores propios de una globalización del conocimiento que caminan hacía sinergias y conocimientos compartidos.
