The Synergistic Effects of Combined Use of Mentha longifolia, Thymus carmanicus, and Trachyspermum copticum on Growth Performance, Feed Utilization, and Expression of Key Immune Genes in Rainbow Trout (Oncorhynchus mykiss)

Medicinal plants exhibit remarkable positive effects on different aspects of fish physiology. This study aimed to evaluate the possible impact of a combination of plants (Mentha longifolia, Thymus carmanicus, and Trachyspermum copticum) on growth performance, immune responses and key immune gene expression of rainbow trout. For this purpose, four diets were designed, including zero, 0.25, 0.5, and 1% of a mixture of plants per kg of diet, representing dietary treatments of control, T1, T2, and T3, respectively. Two hundred forty fish (weighing 23.11 ± 0.57 g) were fed 3% of body weight twice a day for 45 days. The results showed that growth parameters of weight gain (except for T1) and FCR were significantly improved in fish receiving all levels of plants, with T3 showing the best growth results. Digestive enzymes activities were notably increased in T1 and T2 compared to the control. Stress biomarkers (glucose and cortisol) were significantly decreased in T1 and T2, while T3 was not significantly different from the control. Immunological responses were significantly improved in T2, while T1 andT3 did not show a statistical difference in terms of lysozyme activity. Catalase activity was noticeably decreased in T1, although superoxide dismutase and malondialdehyde were highest in T2. Immune-related genes were significantly up-regulated in T3 compared to other treatments. Also, antioxidant enzyme coding genes were strongly up-regulated in T2 and T3. Overall, the present results suggest that 1% inclusion of the mixture of M. longifolia, T. carmanicus, and T. copticum (T2) can be used to improve the growth and immunity of rainbow trout.

Prediction and Visualization of Non-Enhancing Tumor in Glioblastoma via T1w/T2w-Ratio Map

One of the challenges in glioblastoma (GBM) imaging is to visualize non-enhancing tumor (NET) lesions. The ratio of T1- and T2-weighted images (rT1/T2) is reported as a helpful imaging surrogate of microstructures of the brain. This research study investigated the possibility of using rT1/T2 as a surrogate for the T1- and T2-relaxation time of GBM to visualize NET effectively. The data of thirty-four histologically confirmed GBM patients whose T1-, T2- and contrast-enhanced T1-weighted MRI and 11C-methionine positron emission tomography (Met-PET) were available were collected for analysis. Two of them also underwent MR relaxometry with rT1/T2 reconstructed for all cases. Met-PET was used as ground truth with T2-FLAIR hyperintense lesion, with >1.5 in tumor-to-normal tissue ratio being NET. rT1/T2 values were compared with MR relaxometry and Met-PET. rT1/T2 values significantly correlated with both T1- and T2-relaxation times in a logarithmic manner (p < 0.05 for both cases). The distributions of rT1/T2 from Met-PET high and low T2-FLAIR hyperintense lesions were different and a novel metric named Likeliness of Methionine PET high (LMPH) deriving from rT1/T2 was statistically significant for detecting Met-PET high T2-FLAIR hyperintense lesions (mean AUC = 0.556 ± 0.117; p = 0.01). In conclusion, this research study supported the hypothesis that rT1/T2 could be a promising imaging marker for NET identification.

A process evaluation of patient care needs using the Post- Stroke Checklist: a prospective study

Objective: To assess the utility of the modified Post-Stroke Checklist (mPSC) to identify impairments and care needs of patients with stroke (PwS) in an inpatient rehabilitation setting. Methods: Prospective observational design with consecutive admission of PwS (n = 44) at a tertiary rehabilitation facility. The post-stroke checklist was administered at hospital discharge (T1) and 3 months post-discharge (T2). Furthermore, validated questionnaires assessed function and participation, including the Clinical Functioning Information Tool (ClinFIT) on admission (T0), T1 and T2. Results: Participants’ mean age was 67.7 years (standard deviation; SD) 14.6), 58% of participants were female, and the mean length of inpatient stay was 32.7 days (SD 22.4). At T1, 80% and at T2 only 60% of participants reported ≥1 stroke-related problem (mean 5.3 (SD 3.3) and 3.6 (SD 2.8), respectively). Half of participants were referred to physiotherapy/occupational therapy, and 36% to specialist clinics following discharge. The most prevalent problems included: life after stroke (62.2%), fatigue (55.6%), activities of daily living, and mobility (51.1% each). Compared with T1, at T2 there was an observed reduction in all mPSC items, except pain and incontinence. Participants showed improved function at T1 and T2 (Extension Index, ClinFIT set), from T0 to T1 and T0 to T2 (p<0.001, with large effect sizes). Conclusion: The mPSC is feasible to implement in an inpatient rehabilitation setting and community. It can identify relevant stroke-related problems, and hence facilitate targeted intervention.

Night-eating, Overweight/obesity and Sleep Quality

PurposeImpaired sleep has been reported to be a consequence of overweight/obesity. However, sleep-disrupting behaviour that tend to coexist with overweight/obesity are also independent risk factors for impaired sleep such as night-eating, alcohol use, insufficient physical activity (PA), electronic device use and stress/affective distress. Thus, it is unclear whether night-eating and measures of body fatness will still predict sleep quality once concurrent behaviour and affective state are taken into account. MethodsOnline questionnaires asked participants about sleep quality, night-eating, alcohol use, electronic device use and stress/affective distress at T1 (baseline) and T2 (3-months later). Height, weight and waist and hip circumference was measured at T1 and objective physical activity (PA) was assessed over 24-hours (using actigraphy) in 161 participants at T1 and T2. ResultsAt T1, night-eating was related to poorer subjective sleep quality, longer sleep onset latency, lower sleep efficacy, more sleep disturbances and daytime dysfunction and obesity category was related to daytime dysfunction after controlling demographics and covariates. At T2, high BMI predicted lower sleep efficacy after controlling T1 sleep components, demographics and covariates. ConclusionNight-eating and obesity category were associated with multiple impairments in sleep quality, but only high BMI predicted sleep quality at T2. Thus, night-eating and measures of body fatness predicted sleep quality components at T1 and T2 even after co-existing behaviour and emotional states were taken into account.Level of EvidenceLevel III, evidence obtained from well-designed cohort.

Enhancing teachers’ classroom communication skills – Measuring the effect of a continued professional development programme for mainstream school teachers

Continued professional development (CPD), tailored to teachers’ needs and expectations, is required for updated skills and knowledge. In this study, twenty-five teachers working with first and second grade students participated in an 11-week programme focusing on enhancing classroom communication. The participating teachers were randomly assigned to either a direct intervention track (intervention) or a delayed intervention track (waiting control). Teachers’ perceptions of activities and interactions in the classroom and self-efficacy were assessed on three occasions: T1, T2, and T3. The direct intervention track received intervention between T1 and T2, while the delayed intervention track received intervention between T2 and T3. A percentage change score for changes between T1 and T2 was calculated, to compare the direct and delayed intervention tracks and assess any intervention effect. Results revealed no significant difference between the groups, i.e., the intervention had no effect on teacher self-reports. The teachers gave an overall positive evaluation of the CPD. Thematic analyses revealed continued need for professional development and insights into the reciprocal influence of student and teacher behaviour. The quantitative and qualitative results paint somewhat different pictures showing the need of mixed methods when analysing these kinds of data.

Association between Frequency of Toothbrushing and Metabolic Syndrome among Adolescents: A 5-Year Follow-Up Study

This study longitudinally examines the relationship between the frequency of toothbrushing and the development of selected components of metabolic syndrome (MetS), along with the potential role of salivary biomarkers in this relationship. In 2014, 6317 12-year-old children underwent health examinations (T1), of which, 348 children participated in the second stage of data collection in 2019 (T2). The association between the change in the metabolic status during the 5-year follow-up examination (between T1 and T2) and frequency of toothbrushing was assessed using multinomial logistic regression analyses. At T2, healthy adolescents had significantly higher odds of toothbrushing twice or more daily compared with adolescents with components of MetS (OR = 1.99, 95% CI 1.15–3.45). Adolescents who were healthy at T1 but developed components of MetS at T2, had significantly higher frequencies of dining-out compared with adolescents with components of MetS at both T1 and T2 (OR = 0.09, 95% CI 0.02 to 0.49). Adolescents who were ‘healthy’ at both T1 and T2 had significantly (p < 0.05) lower levels of C-reactive protein (T2), insulin (T1 and T2), interleukin-6 (T1) and adiponectin (T1) compared with adolescents who had components of MetS. Toothbrushing and frequency of dining-out were associated with the presence of MetS components.

Comparison of two doses of eCG for obtaining embryos in llama

The study was developed at the Pampa del Arco Experimental Center of the National University of San Cristóbal de Huamanga, the objective was to evaluate doses of 800 IU (T1) and doses of 1000 IU (T2) of eCG to obtain embryos. Eight adult female llamas were used, distributed four in each treatment (T1 and T2), with a body condition of 2.5, these were evaluated by ultrasound with a 7.5 MHz rectal linear transducer. Hormonal treatments began when the animals had a follicle> 7 mm. The application of eCG was 72 hours after the induction of ovulation of the dominant follicle with GnRH, on day 7 PGF2α was applied, natural mounting was performed plus GnRH (1ml), on day 15 the collection and evaluation of embryos was performed. The results obtained were the pre-ovarian stimulation follicular diameter of 8.3 mm and 9.1 mm for T1 and T2 respectively, the number of pre-ovulatory follicles was 6.33 and 5.50 for T1 and T2 respectively, the diameter of follicles pre-ovulatory was 11.2mm and 10.6 mm for T1 and T2 respectively, average of embryos recovered per donor was 4.66 ± 0.81 and 3.50 ± 0.54 embryos for T1 and T2 respectively, with a significant difference (p <0.05) and the quality of embryos had 35.7% and 38.1% of embryos of excellent quality, 28.6% and 33.3% of good quality, 10.7% and 9 , 5% of regular quality, 10.7% and 0% of poor quality, for T1 and T2 respectively and 14.3% and 19.0% of non-transferable embryos for T1 and T2 respectively, with no statistical difference (p≥0, 05). It is concluded that the number of embryos recovered with a dose of 800 IU of eCG is higher compared to the dose of 1000 IU of eCG (p <0.05) and that there is no association between the applied dose of eCG and the quality of the llama embryos (p≥0.05)

Feasibility and Acceptability of ‘VitaVillage’: A Serious Game for Nutrition Education

Computer games have previously been used to improve nutrition knowledge in children. This paper describes the acceptability and feasibility of a serious game, “VitaVillage”, for improving child nutrition knowledge. VitaVillage is a farming-style game in which the player undertakes quests and completes questions aimed at increasing several aspects of nutrition and healthy eating knowledge. Children aged 9–12 years in two primary schools (control vs. intervention) completed a nutrition knowledge questionnaire at baseline (T1) and after 1 week (T2). Participants at the intervention school (n = 75) played VitaVillage for 20 minutes on two occasions. Control participants (n = 94) received no nutrition education. Likeability question scores and written feedback from intervention participants was reported qualitatively. Paired sample t-tests were used to compare T1 and T2 nutrition knowledge changes between control and intervention participants. Engagement with VitaVillage improved children’s overall nutrition knowledge (Mean increase of 2.25 points between T1 and T2, Standard Deviation (SD) 6.31, p = 0.035) compared to controls. The game was liked overall (mean score 77 (SD 24.6) on scale of 0–100) and positive feedback was given. Results indicate that VitaVillage has the potential to be successful as a nutrition education tool. In the future, VitaVillage’s content and gameplay will be revised, extended and evaluated for its long-term impact on eating behaviour and knowledge changes.

Assessment of Safety of Remdesivir in Covid −19 Patients with Estimated Glomerular Filtration Rate (eGFR) < 30 ml/min per 1.73 m^2

Purpose Safety of remdesivir in patients with renal impairment is unknown. Incidence of liver injury secondary to remdesivir is also unknown. The objective of this study is to assess the incidence of acute kidney injury (AKI) and to trend the liver enzymes during remdesivir treatment and change in eGFR from baseline to end of treatment as well as 48 h post completion of remdesivir therapy. Methods This is a retrospective chart review study including adult patients admitted with COVID-19 receiving remdesivir with a baseline eGFR < 30 ml/min per 1.73 m^2 from December 2020 to May 2021. The primary outcome was to assess the incidence of AKI and hepatic injury. The secondary outcome was to assess the efficacy of remdesivir defined by change in oxygen requirement. Results Seventy-one patients were included in the study. Patients experienced an improvement in eGFR from baseline (T0) to end of remdesivir treatment (T1), as well as 48 h after the end of the treatment (T2) ( + 30.3% and + 30.6% respectively, P < .0001). Creatinine reduced from baseline (T0) to T1 and T2 (-20.9% and −20.5% respectively, P < .0001). Creatinine clearance improved from baseline to T1 and T2 ( + 26.6% and + 26.2% respectively, p < .0001). Elevation of aminotransferase (AST) was observed at T1 ( + 2.5%, P = .727), however, AST reduction was seen at T2 (-15.8%, P = .021). Elevation in alanine transaminase (ALT) was observed at T1 and T2 ( + 25% and + 12%, P = .004 and P = .137 respectively). Both direct and total bilirubin remained stable and were not significantly changed from baseline. Conclusion Our study showed that remdesivir use in renally-impaired patients with eGFR < 30 ml/min is safe. Remdesivir may be considered as a therapeutic option in this population with COVID-19 infection.
