Parents and caregivers knowledge of school readiness for children admitted to Grade R and Grade 1
Authors: De Witt Patricia Ann , Du Toit Kirsten , Franzsen Denise 
Published: May 2020

Introduction: Children with scholastic difficulties, including failure to adapt to or thrive in formal schooling, are frequently referred to occupational therapists. Assessment of these children indicates that many of them have not attained the essential school-readiness skills. Concerns have been raised that parents/caregivers often only consider school-readiness with respect toage rather that other developmental milestones. Research has found that the parents' or caregivers' understanding and abilityto determine their children's development in relation to school-readiness is important if the child is to succeed academically. The purpose of this study was to explore parents' or caregivers' knowledge of school-readiness as per the expectations for formal schooling as defined by the current National Curriculum and Assessment Policy Statement (CAPS) and the Independent Schools Association of Southern Africa, (ISASA).Method: This study used a quantitative, descriptive, cross sectional survey research design. Stratified sampling was used to select a sample of parents or caregivers of children admitted to Grade R and Grade 1 level at schools in the Gauteng Province. A self-report questionnaire, specifically designed from the literature was circulated to parents/caregivers by participating schools.Results: There was a 41.2% return rate, but only 180 returned questionnaires could be analysed. The results found that that57.9% of the participants had the correct expectation of school-readiness in ten learning areas within the questionnaire. Participants viewed school-readiness most correctly in the learning areas of Thinking and reasoning (78.9%) and Motor ability (76.8%) while the learning areas of Activities of daily living (ADL) (48.9%), Reading and viewing (48.2%) and Language structure and use (33.7%) were rated with less accuracy, with both under-estimations and over-estimations reported. The mother's level of education was the single demographic factor found to have significance with respect to knowledge of variables related to school-readiness.Conclusion: The parents/caregivers in this study had a fair understanding of some of the variables included in school-readiness, but their ability to determine others, including ADL, was limited. Occupational therapists should be cognisant of the curriculum criteria for school-readiness and should play a role in raising awareness of school-readiness criteria among parents and caregivers wherever possible, to prevent scholastic under-achievement due to lack of school-readiness.
Key words: Awareness of school-readiness, activities of daily living, reading and viewing skills, language structure and use, mother's levelof education

Lingual cyst with respiratory epithelium (LCRE) is a very rare congenital cyst of the tongue, floor of the mouth, pharynx or hypopharynx with 21 cases reported in the literature (1, 2). Differential diagnosis is very important for patients presenting with lingual cysts, as this may impact treatment and follow-up. LCRE should be included in the different diagnosis of dermoid cyst (3), teratoid cyst (4), epidermoid cyst (5), thyroglossal duct cyst (6), lymphoepithelial cyst (7), mucocele or ranula (8). Each entity has a peculiar histologic presentation, although the clinical aspect may be very similar (1). The dermoid cyst is lined by a keratinized squamous epithelium and contains skin appendages in the cyst. Epidermoid cyst is similar to the dermoid cyst but is characterized by non-keratinized squamous epithelium and has a lumen filled of keratin. Teratoid cyst contains derivatives of the endoderm, ectoderm and/or mesoderm. The thyroglossal duct cyst is usually lined by columnar, stratified squamous epithelium, or an intermediate transition type of epithelium, with the mandatory presence of thyroid tissue in the cyst wall. Lymphoepithelial cyst is identified by the presence of the lymphoid aggregates in the cyst wall. A mucous retention cyst, so called mucocele or ranula, contains mucin and granulation tissue (1).

Authors: Daniels Nicola , Gillen Patricia , Casson Karen 
Published: May 2020

BackgroundEngagement of frontline practitioners by academic researchers in the research process is believed to afford benefits toward closing the research practice gap. However, little is known about if and how academic researchers engage nurses, midwives, or therapists in research activities or if evidence supports these claims of positive impact.MethodA scoping review was undertaken using the Arksey and O'Malley (2005) framework to identify the extent to which this phenomenon has been considered in the literature.ResultsAn iterative search carried out in CINAHL, Pubmed, Medline, and Embase retrieved 32 relevant papers published 2000 to 2017, with the majority from the last 2-years. Retained papers described or evaluated active engagement of a practitioner from nursing, midwifery, and therapy disciplines in at least one stage of a research project other than as a study participant. Engagement most often took place in one research activity with few examples of engagement throughout the research process. Limited use of theory and variations in terms used to describe practitioner engagement by researchers was observed. Subjective perspectives of practitioners' experiences and a focus on challenges and benefits were the most prominently reported outcomes. Few attempts were found to establish effects which could support claims that practitioner engagement can enhance the use of findings or impact health outcomes.ConclusionIt is recommended that a culture of practitioner engagement is cultivated by developing guiding theory, establishing consistent terminology, and building an evidence base through empirical evaluations which provide objective data to support claims that this activity can positively influence the research practice gap.

Published: May 2020

Case:
We encountered a case of locking of the distal radioulnar joint after a traumatic injury that restricted the supination and pronation of the wrist. The locking was released surgically with a good 2-year outcome. We found a tear between the dorsal aspect of the joint capsule and the triangular fibrocartilage complex (TFCC). The tear allowed the TFCC to displace volarly and become entrapped against the volar aspect of the ulnar head.

Conclusion:
The open approach facilitated visualization and understanding of this unusual injury pattern and allowed direct repair. Joint incongruity may not occur despite a locked joint.
PMCMC for Term Structure of Interest Rates under Markov Regime Switching and Jumps

Published: May 2020

AbstractA parameter estimation method, called PMCMC in this paper, is proposed to estimate a continuous-time model of the term structure of interests under Markov regime switching and jumps. There is a closed form solution to term structure of interest rates under Markov regime. However, the model is extended to be a CKLS model with non-closed form solutions which is a typical nonlinear and non-Gaussian state-space model(SSM) in the case of adding jumps. Although the difficulty of parameter estimation greatly prevents from researching models, we prove that the nonlinear and non-Gaussian state-space model has better performances in studying volatility. The method proposed in this paper will be implemented in simulation and empirical study for SHIBOR. Empirical results illustrate that the PMCMC algorithm has powerful advantages in tackling the models.
Single Image Dehazing with V-transform and Dark Channel Prior
Authors: Wang Xiaochun , Sun Xiangdong , Song Ruixia 
Published: May 2020

AbstractSingle image dehazing algorithm based on the dark channel prior may cause block effect and color distortion. To improve these limitations, this paper proposes a single image dehazing algorithm based on the V-transform and the dark channel prior, in which a hazy RGB image is converted into the HSI color space, and each component H, I and S is processed separately. The hue component H remains unchanged, the saturation component S is stretched after being denoised by a median filter. In the procession of intensity component, a quad-tree algorithm is presented to estimate the atmospheric light, the dark channel prior and the V-transform are used to estimate the transmission map. To reduce the computational complexity, the intensity component I is decomposed by the V-transform first, coarse transmission map is then estimated by applying the dark channel prior on the low frequency reconstruction image, and the guided filter is finally employed to refine the coarse transmission map. For images with sky regions, the haze removal effectiveness can be greatly improved by just increasing the minimum value of the transmission map. The proposed algorithm has low time complexity and performs well on a wide variety of images. The recovered images have more nature color and less color distortion compared with some state-of-the-art methods.

Abstract

Introduction: Social competences are indispensable in occupations reliant on interpersonal interactions, such as in medical professions, e.g. nursing, conditioning not only the effective construction of interpersonal relationships, but ever more often emphasizing a positive impact on strengthening coping skills in stressful situations. The object of our study was to assess the connection of social competences with the sense of general mental health and intensity of stress in the group of nurses.

Materials and methods: In the study took part 291 nurses (ages 23–63, mean job seniority 11 years, SD = 10.22). We used the Social Competence Questionnaire (KKS) according to Anna Matczak, the Perceived Stress Scale (PSS-10), as adapted by Zygfryd Juczyński and Nina Ogińska-Bulik, and the General Health Questionnaire (GHQ-28) in the adaptation of Zofia Makowska and Dorota Merecz to collect information for the study.

Results: Stress intensity among respondents averaged 16.83 points (SD = 4.47). In the 4 analyzed indicators of the GHQ-28, the mean point score was: somatic symptoms M = 8.45, anxiety and insomnia M = 8.75, functional disorders M = 8.07, depression symptoms M = 2.46. 38.1% of the results of the level of general mental health were in the range 5–6, which is the average level of mental health perceived in the group of nurses.

Conclusions: The level of perceived stress among more than half of the surveyed group of nurses was average (52.6%). The level of social competences is not significantly correlated with the intensity of stress experienced. The level of general mental health of 38.1% of the nurses fell in the range of average. The level of social competences significantly correlates with the general mental health status of the nurse respondents (R = -0.254, p < 0.001).

Abstract
Objectives: To observe the effect of an "Internet plus medical"-based health management service model in patients with nonalcoholic fatty liver disease (NAFLD) and to explore an effective model for NAFLD health management to provide a reference for NAFLD treatment and nursing.Methods: The present study was a randomized, controlled, parallel-group comparison trial. A total of 519 patients with NAFLD were randomly assigned to a routine health education group (N=258) or a health management platform group (N=261). The routine health education group received routine health education, and the health management platform group was treated with the "Internet plus medical"-based health management service model to manage NAFLD. The new model provides closed-loop services for the prevention and rehabilitation of NAFLD through the process of grouping, filing, evaluating, planning, intervening, assessing stage and following up. The two groups were observed for 24 weeks. The results of basic indicators, laboratory indicators, body composition analyses, controlled attenuation parameters (CAP) and quality of life assessment questionnaires were used as evaluation indices. All data of the participants were collected and analyzed prior to and following the intervention, and the differences between the two groups were compared.Results: Compared with the routine health education group, the NAFLD health management service model based on “Internet plus medical” treatment effectively reduced the weight (-3.80±3.11vs -0.12±3.42, P =0.047), body mass index (BMI) (-1.73±1.20 vs -0.14±1.68, P =0.031), CAP (-48.42±10.13 vs 4.13±7.45, P =0.044), aspartate transaminase (AST)/alanine aminotransferase (ALT) value (0.18±0.37 vs 0.04±0.11, P = 0.037), body fat content (-2.24±2.58 vs -0.86±2.78, P =0.194) and visceral fat area (-10.87±15.34 vs -0.55±19.13, P =0.047) of NAFLD patients and improved the quality of life of NAFLD patients in terms of physiological role (96.59 ±11.31 vs 90.69 ± 13.49, P=0.027), vitality (86.57±6.07 vs 81.94±5.78, P=0.001) and general health (78.05±6.35vs 73.61±10.12, P=0.044).Conclusions: The results of the present study preliminarily confirm the validity and development prospects of the "Internet plus medical"-based health management service model in NAFLD. This finding suggests that the model is an evidence-based model of health education and management for NAFLD prevention in China.

Abstract
BackgroundYellow seed breeding is an effective method to improve the oil content in rapeseed. Yellow seed coat color formation is influenced by various factors, and no clear mechanisms are known. In this study, Bulked segregant RNA-Seq (BSR-Seq) of BC9 population of Wuqi mustard (yellow seed) and Wugong mustard (brown seed) was used to identity the candidate genes controlling the yellow seed color in Brassica juncea L.ResultsYellow seed coat color gene was mapped to chromosome A09, and differentially expressed genes (DEGs) between brown and yellow bulks enriched in the flavonoid pathway. A significant correlation between the expression of BjF3H and BjTT5 and the content of the seed coat color related indexes was identified. Two intron polymorphism (IP) markers linked to the target gene were developed around BjF3H. Therefore, BjF3H was considered as the candidate gene. The BjF3H coding sequences (CDS) of Wuqi mustard and Wugong mustard are 1071-1077bp, encoding protein of 356-358 amino acids. One amino acid change (254, F/V) was identified in the conserved domain. This mutation site was detected in four Brassica rapa (B. rapa) and six Brassica juncea (B. juncea) lines, but not in Brassica napus (B. napus).ConclusionsThe results indicated BjF3H is a candidate gene that related to yellow seed coat color formation in Brassica juncea and provided a comprehensive understanding of the yellow seed coat color mechanism.

Abstract
Background: Male sterility contributes strongly to hybrid seed purity and production in Brassica crops. To detect plant phenotypes and the gene expression patterns involved in bioprocess of an Ogura cytoplasmic male sterility line (Ogura-CMS), a dominant genic male sterility line (DGMS) and their maintainer line, we analyzed the transcriptomes of broccoli florets among the isogenic Ogura-CMS (T54C), DGMS (T54M) and inbred lines (T54S).Results: There were respectively 505, 585 and 469 upregulated genes, and 1109, 1073 and 543 downregulated genes in the comparison groups of T54C and T54M, T54C and T54S, and T54M and T54S. The head weight and head width showed stronger performance in the Ogura-CMS than the DGMS line or maintainer line. The Ogura-CMS line showed poorer performance in seed yield and seed germination than the DGMS line or maintainer line. The DGMS line had longer maturation and flowering periods than the Ogura-CMS and maintainer lines. The plant hormone genes, auxin (TIR1, GH3 and SAUR) and salicylic acid (SA) (NPR1), and adenosine triphosphate-binding cassette (ABC) transporters-related genes (ABCB1 and ATM) were highly up-regulated in T54C compared with T54M or T54S. The brassinosteroid upregulated gene CYCD3 related to the function of late-flowering and delaying senescence in plants, was detected in T54M over two seasons.Conclusions: Among the isogenic Ogura-CMS, DGMS and inbred lines of broccoli, the Ogura-CMS line showed strong performance in head yield than the DGMS line or the inbred line. The DGMS line had longer days to flowering than the Ogura-CMS and inbred lines. However, the inbred line presented a higher seed yield and seed germination rate than the DGMS or Ogura-CMS line. This study found that some potential plant hormone genes, auxin (TIR1, GH3 and SAUR) and SA (NPR1), and ABC transporters related genes (ABCB1 and ATM) might play a key role in regulation of the developmental trait in the Ogura-CMS line. The BR- upregulated gene CYCD3 may function in late-flowering and delaying senescence of broccoli consistent with the investigations conducted over two seasons. Our findings provided a possible explanation for physiological and developmental differences of broccoli among the Ogura-CMS, the DGMS and the inbred lines.

Abstract
Background: CD44 is an important surface marker of breast cancer stem cells (BCSCs), but it is unclear whether it is involved in the stemness of BCSCs. This has limited the development of new therapeutic strategies for breast cancer. Previous studies have shown that many CD44 variants generated through alternative splicing are involved in the development of breast cancer, but their exact role in BCSCs remains unclear. Therefore, we analyzed the CD44 transcript variants in BCSCs derived from the MDA-MB-435 cell line, and aimed to investigate whether CD44s knockdown could affect the biological characteristics of BCSCs.Methods: CD44+/CD24- cells were isolated among the MDA-MB-435 cells by flow cytometry, and the CD44 transcript variants were detected by RT-PCR in CD44+/CD24- cells. Due to the high expression of CD44 standard splice isoform (CD44s) in CD44+/CD24- cells, CD44s knockdown was generated using small hairpin RNA (shRNA). The effects of CD44s knockdown on the biological characteristics of BCSCs was detected using cell proliferation assay, colony formation assay, cell cycle and apoptosis assay, tumor sphere formation assay, would-healing assay, and Matrigel invasion assay. Tumorigenesis of the CD44+/CD24- cells with CD44s knockdown was investigated in vivo with NOD/SCID mice. The expression of cancer stem cell stemness-related genes, such as Bcl-2, CCNE2, EGFR, MMP7, Muc1, and Myc was also detected by qPCR.Results: Our results revealed that the mRNA expression of CD44 transcript variants was heterogeneous, and CD44s is highly expressed in BCSCs. CD44s depletion inhibited the proliferation, made cell cycle stay in G0/G1 phase, promoted the apoptosis and necrosis of BCSCs, inhibited the ability of self-renewal and invasion along with the expression of cancer stem cell-related genes in BCSCs. Moreover, CD44s knockdown inhibited the tumorigenesis ability in vivo.Conclusion: Our findings revealed that CD44s is the predominant isoform expressed in BCSCs, and is an important molecule for maintaining the properties of BCSCs. Targeting CD44s in BCSCs may be a potential new direction for breast cancer treatment.

Abstract
BackgroundTermites account for natural biomass utilization systems (NBUS) that evolved the ability to overcome the overall recalcitrance of lignins towards lignocellulose transformation processes. With the objective of applying this capacity to the conversion of technical lignins produced by biorefineries, a higher wood-feeding termite species, Nasutitermes ephratae was fed with a commercial grass soda lignin (Protobind 1000, PB1000). The survival rates of Protobind 1000-fed termites were determined as well as changes in the structure of gut bacterial community and in the chemical composition of this technical lignin. ResultsThe ingestion of PB1000 by worker castes of N. ephratae was revealed by Pyrolysis-Gas Chromatography Mass Spectrometry (Py-GC/MS) analyses directly performed on termites. Survival rates were reduced by two –fold in the termites fed with PB1000 compared to controls. The relative abundance of Firmicutes and Bacteroidetes increased in the gut bacterial community of termites fed with PB1000. The digestion of PB1000 by termites triggered an increase in the syringyl-to-guaiacyl (S/G) ratios. These changes in the chemical composition of PB1000 in the gut of termites was marked by a decrease in relative content of free phenolic monomers.ConclusionThis work showed the abilities of digestive tract of a wood-feeding higher termite species, N. ephratae to metabolize the fraction of the volatile phenolic monomers of PB1000. Overall, our results provide insights into the bacterial lineage candidates for development of bacterial inoculum for pretreatment processes in valorization of technical lignin in biorefinery.
