Microbiota Structure

Background: Although functional bacteria are widely used in aquaculture water treatment, whether they affect the indigenous microbiota and whether the impact is persistent remain unclear. Therefore, we aimed to explore the denitrification effect of Pseudomonas furukawaii ZS1 isolated from a grass carp culture pond in nitrogen-rich aquaculture water, and determine whether its effect on the microbiota structure of the aquaculture water was persistent. Methods: Three each of treatment and control groups were set up, and P. furukawaii ZS1 was added to the treatment group. The concentrations of ammonia nitrogen, nitrite, and nitrate, and the pH of each sample were measured for eight consecutive days. Changes of microbiota composition in the water were analysed via high-throughput sequencing. Results: Ammonia, nitrite, and nitrate concentrations were substantially lower in the treatment group than in the control group. There were significant differences in the microbiota structure between treatment and control groups, especially on days 2–7 after adding P. furukawaii ZS1. Furthermore, significantly enriched bacterial genera in the treatment group were initially higher in number than inhibited genera, but subsequently reverted to being lower in number. Conclusions: These results provide theoretical guidance for the effective use of P. furukawaii ZS1 to control aquaculture water.

This paper investigates the efficiency of text messaging as an English as a Foreign Language (EFL) instructional tool to enhance learner autonomy and perception at the Islamic Azad University-South Tehran Branch, Iran. The study considers seventy-four learners to participate in the study after the administration of an Oxford Placement Test to measure their proficiency level. Participants are randomly assigned in experimental and control groups, including 37 participants each. A questionnaire is used as a pretest and posttest to measure learners` autonomy. Participants from the experimental group use text messaging (the treatment) to receive instructions, whereas those from the control group receive traditional classroom instructions in a face-to-face channel. A semi-structured interview is also used to collect date on experimental group participants` perception in using MALL in classrooms. The results reveal remarkable differences between the experimental and control groups’ means on their learner autonomy scores. However, the impact of the independent samples t-test has shown that there is no statistically meaningful gender difference among the learners regarding their autonomy scores. The findings based on the semi-structured interview showed complimentary views on MALL. The current study is beneficial since its outcomes could be relevant for EFL curriculum developers and English language teachers in the use of mobile learning and text messaging in the English classroom.

Perineal Care

Background: Educating mothers during their postpartum period could potentially help them to overcome some important phases after giving birth. The process of education is evaluated based on the mothers’ knowledge about their independent self-care. Independency is an activity that is started individually and is done based on self-capability. The independency in the postpartum care is not only important to decrease the mother’s mortality and morbidity rate, but it is also crucial to strengthen and improve the post-partum mother’s healthy behavior during the perineal care. Providing education using Android-based application called BUBI Care could be potential to facilitate a more dynamic transfer of knowledge to the postpartum mothers.Aims: To analyze the knowledge, skills, and independence of primipara postpartum mothers in independent perineal care before and after accessing BUBI Care app. Research Method: employing quasi experimental research with pre-test and post-test design with control group design. The sample for this research were 19 pregnant mothers TM III (pregnancy age of ? 38 weeks) on each group. The treatment group was educated using BUBI Care Android app that was conducted at one of Public Health Center. The control group was educated without BUBI Care that was conducted at a Midwife Practice Clinic. The research was conducted on September to October 2020. Study Result: According to the Wilcoxon test, there was a difference in the pre-test knowledge of the treatment and control groups with the similar median of 53 and p-value of 0.666, the treatment group showed their scores improved to 80 on the post-test while the control group stayed at 53 with the p-value of 0.000. It means that BUBI Care app education influences the post-test. On the other hand, the perineal care skill saw a difference between the intervention and control groups. The intervention group had a mean of 70.05 and 56.68 for the control group with the p-value of 0.002 which means that there was an influence from the BUBI Care app education. Additionally, Mann Whitney test showed that the intervention group had a mean score of 78.95, but the control group only had 49.26, the total difference between the two are 29.69 with the p-value of 0.000. It can be concluded that there is a significance in difference in the independency rate from the provision of BUBI Care Android app education.Conclusion:  there is a significance effect on the intervention group in terms of Android based usage.

We conducted 215 evaluations for plaque, stain, and calculus in 120 dogs at two research sites. Dogs were balanced in groups of five according to baseline plaque index scores; groups were randomly assigned to treatment or control dietary regimens. Dental cleanings were done on Day 0. Dogs in the treatment group were fed a food formulated to reduce accumulation of plaque, stain, and calculus. Control group dogs were fed a commercially available dry dog food. No other foods, treats, or snacks were given to either group. We graded 22 teeth for plaque accumulation on Day 7 and for stain and calculus accumulation on Day 21. Six trials were conducted and the results reported as a combined mean for all treatment and control groups. Dogs fed the treatment food had significantly less plaque, stain, and calculus accumulation (p=0.001) than dogs fed the control food. Plaque, stain, and calculus accumulation can be reduced by dietary means.

Objectives: Clinical trials have reported decreased blood loss with the use of tranexamic acid during joint reconstruction. The purpose of this study was to assess the individual practice implications of tranexamic acid use in joint replacement surgery. Methods: Health records of adults undergoing total knee arthroplasty and total hip arthroplasty over a 12-month period were retrospectively reviewed. The treatment group comprised patients who received intravenous tranexamic acid perioperatively. The control group comprised patients who did not receive tranexamic acid. Results: Patients in the treatment group (n = 64) and the control group (n = 99) were well matched for demographics, orthopedic diagnosis, and comorbidities. In-hospital postsurgical mean decreases in hemoglobin concentrations were −4.05 g/dL and −4.94 g/dL in the treatment and control groups, respectively (p < 0.001). Postsurgical mean decreases in hematocrit levels were −11.2% and −14.2% in the treatment and control groups, respectively (p < 0.001). Three patients in the treatment group (5%) and 21 patients in the control group (21%) received red blood cell transfusions (p = 0.006). As compared to control, the relative risk of transfusion in the treatment group was 0.23 (95% confidence interval = 0.07–0.76) and the number needed to treat to avoid one transfusion was 7.0 (95% confidence interval = 3.8–14.4). No evidence of thromboembolism or other serious complications were observed in either group. Conclusions: In patients undergoing joint replacement surgery, perioperative administration of tranexamic acid was associated with diminished blood loss and lesser resource utilization.

Children’S Physical Activity

Background: Curriculum-integrated dance programs are a promising but relatively under-researched strategy for increasing children’s physical activity (PA). The aim of this study was to determine the impact of a curriculum-integrated dance program on children’s PA. Methods: A total of 134 primary children aged 7–9 years from 4 New Zealand schools were assigned to either a dance group (n = 78) or a control group (n = 56). The dance group participated in a 6-week curriculum-integrated dance program during school time. Although the dance program focused on curricular learning, fitness and coordination were embedded in the dance sessions. Intensity of PA varied according to the focus of each dance session. PA was measured at baseline and postintervention using a waist-mounted ActiGraph GT3X+ accelerometer for 8 consecutive days. Results: There were no significant intervention effects on PA levels between the dance and control groups postintervention. Conclusion: Dance-embedded learning did not increase overall levels of PA in this study. Future studies may consider assessing longer term effects of a dance-based intervention, or programs that place more focus on PA promotion.

PurposeEmployee engagement has been directly linked to organizational outcomes, and at present, improving employee engagement has increasingly been a main focus for organizations. However, studies evaluating the impact of storytelling interventions on increasing the level of employee engagement are limited. Storytelling is one of the intervention methods that can provide cognitive stimulus to employees, which in turn could change their attitudes toward work including employee engagement. The purpose of this study is to determine the effectiveness of storytelling as an intervention tool for increasing employee engagement in one of the state-owned enterprises (SOEs) in West Java, Indonesia.Design/methodology/approachThis study uses a quantitative method. Employees from a West Java branch of large SOEs were randomly assigned into experimental and control groups. The research design used a pretest and a post-test with an expressive writing method to identify the extent of employee engagement by comparing participant groups and measuring the increase of employee engagement as a result of the storytelling intervention. The experimental group participated in three storytelling sessions that had been set up by panels of experts, while the control group was not given any treatment. The expressive writing analysis was conducted using software that has been developed and tested for validity and reliability. Furthermore, statistical analysis was used to test the results of expressive writing scoring to determine the impact of storytelling interventions.FindingsDirect storytelling is proven to be one of the most effective methods of increasing employee engagement in one of the SOEs in the West Java region. The results of this study showed that there were differences between the experiment and control groups after experiencing a direct storytelling intervention where there was a significant increase in the dimensions of employee engagement. Participants in experimental group had higher scores than participants in control group in most of the employee engagement dimensions. Additionally, expressive writing methods are also proven to be able to provide a stimulus for employees in expressing thoughts, perceptions and motivations for employee engagement in the company.Research limitations/implicationsAs direct storytelling has not been frequently used, especially to improve employee engagement, more studies should be conducted in various settings, with different measurement tools, and in a more controlled environment to confirm the effects of the intervention.Practical implicationsThis paper provides insight into how companies can use direct storytelling to improve the dimensions of employee engagement. Additionally, this research can also be used as a reference by companies in Indonesia, especially SOEs, for applying the same method in an effort to improve work-related attitudes, such as employee satisfaction and organizational commitment.Social implicationsThis study raises social implications in which employees enthusiasm increases in improving personal relationships between employees and storytellers, who are middle or upper management employees. In addition, employees also more appreciate their struggles when starting their careers, so they care more about increasing their role and involvement in the company.Originality/valueThis paper provides resources and information for companies and organizations to improve employee engagement through the implementation of direct storytelling. The focus of this paper is to gain information on the role of direct storytelling in improving employee engagement within a company or organization.

CONTEXT: Fibromyalgia is a syndrome characterized by chronic, diffuse musculoskeletal pain, and by a low pain threshold at specific anatomical points. The syndrome is associated with other symptoms such as fatigue, sleep disturbance, morning stiffness and anxiety. Because of its chronic nature, it often has a negative impact on patients' quality of life. OBJECTIVE: To assess the quality of life and anxiety level of patients with fibromyalgia. TYPE Of STUDY: Cross-sectional. SETTING: Rheumatology outpatient service of Hospital das Clínicas (Medical School, Universidade de São Paulo). METHODS: This study evaluated 80 individuals, divided between test and control groups. The test group included 40 women with a confirmed diagnosis of fibromyalgia. The control group was composed of 40 healthy women. Three questionnaires were used: two to assess quality of life (FIQ and SF-36) and one to assess anxiety (STAI). They were applied to the individuals in both groups in a single face-to-face interview. The statistical analysis used Student's t test and Pearson's correlation test (r), with a significance level of 95%. Also, the Pearson chi-squared statistics test for homogeneity, with Yates correction, was used for comparing schooling between test and control groups. RESULTS: There was a statistically significant difference between the groups (p = 0.000), thus indicating that fibromyalgia patients have a worse quality of life and higher levels of anxiety. The correlations between the three questionnaires were high (r = 0.9). DISCUSSION: This study has confirmed the efficacy of FIQ for evaluating the impact of fibromyalgia on the quality of life. SF-36 is less specific than FIQ, although statistically significant values were obtained when analyzed separately, STAI showed lower efficacy for discriminating the test group from the control group. The test group showed worse quality of life than did the control group, which was demonstrated by both FIQ and SF-36. Even though STAI was a less efficient instrument, it presented significant results, showing that fibromyalgia patients presented higher levels of anxiety, both on the state and trait scales. Thus, patients with fibromyalgia had higher levels of tension, nervousness, preoccupation and apprehension, and higher propensity towards anxiety. CONCLUSION: The three instruments utilized showed efficiency in evaluating fibromyalgia patients. FIQ was found to be the most efficient instrument for discriminating and assessing the impact of fibromyalgia on their quality of life. It can be concluded that such patients have a worse quality of life and higher levels of anxiety.

Over Time

The impact of a six-week indoor wall climbing on the perceptions of self for children with special needs aged 6–12 years was explored. Participants (n = 46) were randomly assigned to the intervention (girls, n = 4; boys, n = 19) and control groups (girls, n = 5; boys, n = 18). Belayers’ and children’s perceptions of efficacy were measured using specifically designed questionnaires and perceptions of competence and global self-worth were measured using Harter’s (1985) Self-Perception Profile for Children for participants with an adaptive age of 8 years or higher. Children’s self-efficacy and belayers’ ratings of children’s efficacy improved significantly, t(21) = 3.9, p = .001, d = .84 and F(2, 44) = 30.03, p < .001, respectively. The children’s judgments of their athletic and social competence and global self-worth, however, did not change over time or differ from the wait-listed control group (p > .05). These results suggest that it is likely that many experiences that enhance self-efficacy may be needed to improve self-perceptions.

Abstract Introduction This study was to establish a method for wound repair in patients with extensive deep burns using fresh allogeneic scalp combined with autologous micrograft. Methods Two patients with burn injuries involving 90% (3rd degree, 70%) and 97% (3rd degree, 85%) total body surface area (TBSA) respectively were treated with fresh scalp allografts donated by 32 males aged (31.5 ± 8.2) years or autologous micrografting. The bilateral limbs with third-degree burns were selected as treatment and control groups. Wounds in the treatment group were treated with fresh allogeneic scalp and autologous micrograft, while wound in the control group received MEEK grafting. Preoperatively, the surgical area on the extremities was calculated to estimate the necessary amount of allogeneic scalp and MEEK grafts. Fresh scalps (0.30 - 0.35 mm) were harvested from each donor to prepare a larger piece of skin allograft. Autologous micrografts were transported onto the epidermis of the skin allograft. The treatment and control group received grafting according to our protocol. The donors received follow-up visits after 3 months to see if there is alopecia and scar hypertrophy. The wound coverage rate was observed in both treatment and control groups on postoperative weeks 2, 3, 4 and 5. Results The donor sites in all allogeneic skin donors healed within 10 days postoperatively. The scalp recovered well without any alopecia or scar hypertrophy during the follow-up visits. The wound coverage rate of the treatment group was approximate to or higher than that of the control group. Conclusions Considering that allogeneic skin is scarce and expensive and the patient’s relatives are willing to help save the patient’s life by donating the scalp, this method may be a feasible clinical treatment option. Applicability of Research to Practice This study is a clinical study which is highly applicable in practice.

Smog warning systems are components of adaptation strategies that are adopted by governments around the world to protect their citizens from extreme episodes of air pollution. As part of a growing research stream on the effectiveness of these systems, this article presents the results of a study on the impacts of an automated phone warning and advising system for individuals vulnerable to air pollution. A sample of 1328 individuals were recruited and randomly assigned to treatment and control groups. The treatment group received smog warning while the control group did not. Data were collected via three phone surveys, two before and one after issuing the smog warning. The comparison between treatment and control groups indicates that exposure to a smog warning improved information on the occurrence of smog episodes (n = 484, OR = 5.58, p = 0.00), and knowledge on protective behaviors. Furthermore, members of treatment group were more likely to avoid exposure to smog episodes by spending more time inside with the windows closed than usual (n = 474, OR = 2.03, p = 0.00). Members of treatment group who take medication in the form of aerosol pumps also kept these devices on themselves more frequently than those of control group (n= 109, OR = 2.15, p = 0.03). The system however had no discernible effects on the awareness of air pollution risks, reduction of health symptoms related to smog and the use of health system services. The absence of health benefits could be related to the lower actual exposure to air pollution of such vulnerable groups during winter.
