Objective

Parent-mediated programmes have been found to be cost effective for addressing the needs of the children and adolescents with Neurodevelopmental Disorders (NDD) in high-income countries. We explored the impact of parent-mediated intervention programmes in South Asia, where the burden of NDD is high.

Methods

A systematic review was conducted using the following databases; PUBMED, MEDLINE, PsycINFO, Google Scholar and Web of Science. Predefined MeSH terms were used, and articles were included if published prior to January 2020. Two independent researchers screened the articles and reviewed data.

Outcomes measures

The review included studies that targeted children and adolescents between 1 and 18 years of age diagnosed with any of four specific NDDs that are commonly reported in South Asia; Autism Spectrum Disorder (ASD), Intellectual Disability (ID), Attention Deficit Hyperactivity Disorder (ADHD) and Cerebral Palsy (CP). Studies that reported on parent or ch ild outcomes, parent-child interaction, parent knowledge of NDDs, or child activities of daily living were included for full text review.

Results

A total of 1585 research articles were retrieved and 23 studies met inclusion criteria, including 9 Randomized Controlled Trials and 14 pre-post intervention studies. Of these, seventeen studies reported effectiveness, and six studies reported feasibility and acceptability of the parent-mediated interventions. Three studies demonstrated improved parent-child interaction, three studies demonstrated improved child communication initiations, five studies reported improved social and communication skills in children, four studies demonstrated improved parental knowledge about how to teach their children, and four studies reported improved motor and cognitive skills, social skills, language development, learning ability, or academic performance in children.

Conclusion

This systematic review of 23 studies demonstrated improvements in parent and child skills following parent-mediated intervention in South Asia. Additional evaluations of locally customized parent-mediated programmes are needed to support development of feasible interventions for South Asian countries.

ABSTRACT

BACKGROUND: Patients who undergo surgery and adjuvant radiation treatment for head and neck cancer often develop dysphagia as a result of this treatment. Improvements in swallow function may be achieved with exercise. The goal of this pilot study was to compare the effectiveness and perceived difficulty of using the head lift exercise and the recline exercise to activate the suprahyoi d musculature in 8 individuals with a history of head and neck cancer.

METHOD: Muscle activation using surface electromyography was examined to determine if the recline exercise activates the suprahyoid muscle groups to the same degree as the head lift exercise. Participants also rated the exertion they experienced to assess how easily patients are able to complete the exercises.

RESULTS: The majority of participants completed both exercises in their entirety on their first attempt. However, ratings of perceived exertion were significantly lower for the recline exercise than the head lift exercise. The head lift exercise activated the suprahyoid musculature to a significantly greater degree than the recline exercise.

CONCLUSION: The recline exercise, in comparison with the head lift exercise, is easier for participants to complete and results in significantly reduced perceptions of fatigue. Results of this study indicate that the recline exercise may be a good pote ntial substitute for the head lift exercise in patient populations that are incapable of performing the head lift exercise, but that the head lift exercise should be prescribed whenever it is viable as it activates target musculature more effectively than the recline exercise.

Abstract

Endoscopic sinus surgery (ESS) is one of the common ENT surgeries performed. Various techniques are available for reducing the blood loss during ESS. The efficacy of cauterization of the SPA in reducing the per-operative blood loss has not been explored in the literature. This study evaluates the efficacy of SPA cauterization prior to sinus surgery and its per-operative and post-operative outcomes. To study the outcomes of endonasal SPA cauterization in patients undergoing ESS. This is a prospective observational study conducted in a tertiary care centre from October 2018 to October 2020. 30 patients underwent ESS where SPA was cauterized by bipolar diathermy in one side of the nasal cavity and in the contralateral side, SPA was not cauterized. The results were tabulated and compared between the cauterized and non cauterized side. p value < 0.05 was considered as statistically significant. Mean blood loss (p value = 0.20), operating t ime (p value = 0.19), surgical field grade, post operative Lund Kennedy Score at 1st, 4th and 12th week were compared and the difference between cauterized and non cauterized was found to be statistically insignificant. In this study, endonasal SPA cauterization did not significantly reduce the intra operative bleeding and surgical field grade in patients undergoing ESS. SPA cauterization did not adversely affect the per operative and post operative outcome and hence authors highlight the fact that it can be safely performed in cases where severe intra operative bleeding is expected and its effectiveness can be studied better in such cases.

Abstract

As there are changing trends in the microbiology of chronic otitis media, this study was carried out to look for the current aerobic microbes and their antimicrobial susceptibilities in patients of chronic otitis media from north Indian region. A total of 322 patients who met the inclusion criteria were studied and aerobic ear swab culture was done under aseptic conditions. Gram staining was performed and antibiotic susceptibility testing was done using Kirby–Bauer disc diffusion method on Mueller–Hinton Agar. A total of 341 culture positive results were obtained from 322 patients. The culture results revealed 10 different aerobic microbes. Gram-positive floras were seen in 152 (44.57%), and Gram-negative in 189(55.43%) isolates. Staphylococcus aureus was the most common isolate present in 131 samples (38.41%), followed by pseudomonas aeruginosa in 101 (29.62%) and proteus in 36 (10.56%). In overall susceptibility of antibiotics aga inst Gram-positive culture isolates, Vancomycin was most effective (97.37%). For Gram-negative microbes, Piperacillin–Tazobactum combination was most effective with overall susceptibility of 79.37% susceptibility. Microbiological assessment of Chronic Otitis Media should be carried out in an area on regular intervals because of the changing patterns of bacteriology and their antimicrobial susceptibilities.

Epigenetic regulation of cellular functions in wound healing

xlomafota13 shared this article with you from Inoreader

Abstract

Stringent spatiotemporal regulation of the wound healing process involving multiple cell types is associated with epigenetic mechanisms of gene regulation, such as DNA methylation, histone modification and chromatin remodeling, as well as non‐coding RNAs. Here we discuss the epigenetic changes that occur during wound healing and the rapidly expanding understanding of how these mechanisms affect healing resolution in both acute and chronic wound milieu. We provide a focused overview of current research into epigenetic regulators that contribute to wound healing by specific cell type. We highlight the role of epigenetic regulators in the molecular pathophysiology of chronic wound conditions. The understanding of how epigenetic regulators can affect cellular functions during normal and impaired wound healing could lead to novel therapeutic approaches, and we outline questions that can provide guidance for future research on epigenetic‐based interventions to promote healing. Disse cting the dynamic interplay between cellular subtypes involved in wound healing and epigenetic parameters during barrier repair will deepen our understanding of how to improve healing outcomes in patients affected by chronic non‐healing wounds.

Vitamin C prevents epidermal damage induced by PM‐associated pollutants and UVA1 combined exposure

xlomafota13 shared this article with you from Inoreader

Abstract

Particulate matter is suspected to be substantially involved in pollution‐induced health concerns. In fact, ultrafine particles (UFPs) contain polycyclic aromatic hydrocarbons (PAHs) known as mutagenic, cytotoxic and sometimes phototoxic. Since UFPs reach blood circulation from lung alveoli, deep skin is very likely contaminated by PAHs coming from either skin surface or blood. As photoreactive, benzo(a)pyrene (BaP) or indenopyrene (IcdP) is involved in the interplay between pollution and sunlight. In order to better characterize this process, experiments were carried out on reconstructed human epidermis (RHE) in a protocol mimicking realistic exposure. Concentrations of PAHs comparable to those generally reported in blood were used together with chronic irradiation to low dose UVA1. On a histological level, damaged cells mainly accumulated in a suprabasal situation, thus reducing living epidermis thickness. Stress markers such as IL1‐α or MMP3 secretion increased, and surpri singly, the histological position of Transglutaminase‐1 within epidermis was disturbed, whereas position of other differentiation markers (keratin‐10, filaggrin, loricrin) remained unchanged. When vitamin C was added in culture medium, a very significant protection involving all markers was noticed. In conclusion, we provide here a model of interest to understand the epidermal deleterious consequences of pollution and to select efficient protective compounds.

xlomafota13 shared this article with you from Inoreader

Exp Ther Med. 2021 Apr;21(4):411. doi: 10.3892/etm.2021.9842. Epub 2021 Feb 25.

ABSTRACT

Gastric cancer is a disease that occurs in the digestive system of humans and remains a problem in the medical field. Wogonoside, a natural flavonoid, has been reported to exert antitumor effects on various types of tumors. However, the effects of wogonoside on gastric cancer remain elusive. The aim of the present study was to detect whether wogonoside treatment could induce apoptosis and ER stress in gastric cancer cells. In the present study, CCK-8 assay was used to detect the cell viability, Annexin V/PI staining was used to detect the cells apoptosis, western blot analysis and real-time PCR analysis was used to detect the endoplasmic reticulum (ER) stress in the AGS and MKN-45 gastric cancer cell lines. Wogonoside treatment reduced the viability of AGS and MKN-45 cells and induced apoptosis. Furthermore, the expression level of caspase-3 and -9 significantly increased following wogonoside treatment compared with that in non-treated cells, and the protein expression levels of proapoptotic Bax and antiapoptotic Bcl-2 increased and decreased, respectively compared with that in the control group. In addition, the phosphorylated protein expression levels of mitogen-activated protein kinase kinase 5 (ASK1) and JNK increased following wogonoside treatment, and the protein expression levels of tumor necrosis factor receptor-associated factor 2 (TRAF2) and serine/threonine-protein kinase/endoribonuclease IRE1 (IRE1α) were also increased following treatment with 50 µM wogonoside for 48 h. Furthermore, the interactions between IRE1α, TRAF2 and ASK1 significantly increased following wogonoside treatment, suggesting that wogonoside induced endoplasmic reticulum (ER) stress in the AGS and MKN-45 cell lines. In addition, small interfering RNA-mediated silencing of IRE1α suppressed the activity of the IRE1α-TRAF2-ASK1 complex and pr evented wogonoside-induced cell apoptosis. In conclusion, the results of the present study suggested that wogonoside exhibited antitumor activity by inducing ER stress-associated cell death through the IRE1α-TRAF2-ASK1 pathway.

xlomafota13 shared this article with you from Inoreader

Exp Ther Med. 2021 Apr;21(4):403. doi: 10.3892/etm.2021.9834. Epub 2021 Feb 25.

ABSTRACT

The present study aimed to analyze gene mutations in patients with β-ureidopropinoase deficiency and establish a rapid detection method for β-ureidopropinoase (UPB1) pathogenic variations by high resolution melting (HRM) analysis. DNA samples with known UPB1 mutations in three patients with β-ureidopropinoase deficiency were utilized to establish a rapid detection method for UPB1 pathogenic variations by HRM analysis. Further rapid screening was performed on two patients diagnosed with β-ureidopropinoase deficiency and 50 healthy control individuals. The results showed that all known UPB1 gene mutations can be analyzed by a specially designed HRM assay. Each mutation has specific HRM profiles which could be used in rapid screening. The HRM method could correctly identify all genetic mutations in two children with β- ureidopropinoase deficiency. In addition, the HRM assay also recognized four unknown mutations. To conclude, the results support future studies of applying HRM analysis as a diagnostic approach for β-ureidopropinoase deficiency and a rapid screening method for UPB1 mutation carriers.

Calcium-binding and coiled-coil domain 2 promotes the proliferation and suppresses apoptosis of prostate cancer cells

xlomafota13 shared this article with you from Inoreader

Exp Ther Med. 2021 Apr;21(4):405. doi: 10.3892/etm.2021.9836. Epub 2021 Feb 25.

ABSTRACT

Prostate cancer (PCa) is considered to be one of the most common tumors in men. Calcium-binding and coiled-coil domain 2 (CALCOCO2) is a known important xenophagy receptor, which mediates intracellular bacterial degradation. To the best of the authors' knowledge, the present study is the first to demonstrate that CALCOCO2 functions as an oncogene in PCa. The results of the current study indicated that CALCOCO2 knockdown suppressed cell proliferation and colony formation, whereas it promoted apoptosis of PCa cells. In addition, knockdown of CALCOCO2 in PCa cells reduced cyclin-E1 and increased p53 protein expression. Bioinformatics analysis revealed that CALCOCO2 was associated with 'autophagosome assembly', 'nucleophagy' and 'nucleic acid metabolic process' biological processes and interacted with sequestosome-1, microtubule-associated proteins 1A/ 1B light chain 3 (MAP1LC3)B, γ-aminobutyric acid receptor-associated protein, IκB kinase subunit γ and MAP1LC3C. Moreover, CALCOCO2 protein levels were indicated to be significantly increased in PCa samples compared with normal prostate tissues. These results suggested that CALCOCO2 may be of value as a diagnostic and therapeutic target in PCa.

Long non-coding RNA OIP5-AS1 contributes to cisplatin resistance of oral squamous cell carcinoma through the miR-27b-3p/TRIM14 axis

xlomafota13 shared this article with you from Inoreader

Exp Ther Med. 2021 Apr;21(4):408. doi: 10.3892/etm.2021.9839. Epub 2021 Feb 25.

ABSTRACT

Oral squamous cell carcinoma (OSCC) accounts for 90% of oral cavity cancer types, but the overall prognosis for patients with OSCC remains unfavorable. Cisplatin (DDP) is an effective drug in OSCC treatment, but DDP resistance weakens its therapeutic effect. Opa-interacting protein 5 antisense RNA 1 (OIP5-AS1) can trigger DDP resistance. The purpose of the current study was to explore the role and mechanism ofOIP5-AS1 in OSCC DDP resistance. In the present study, the expression levels of OIP5-AS1, microRNA (miR)-27b-3p and tripartite motif-containing 14 (TRIM14) were detected by reverse transcription-quantitative PCR. DDP resistance was measured using an MTT assay. Moreover, cell proliferation, migration and invasion were assessed by MTT, Transwell, and Matrigel assays. Protein expression levels of TRIM14, E-cadherin, N-cadherin and Vimentin were d etected by western blot analysis. Putative binding sites between miR-27b-3p andOIP5-AS1 or TRIM14werepredicted with starBase and verified using a dual-luciferase reporter assay. The role of OIP5-AS1 in DDP resistance of OSCC in vivo was measured using a xenograft tumor model. It was observed that OIP5-AS1 was upregulated in DDP-resistant OSCC cells, and the knockdown of OIP5-AS1 improved DDP sensitivity in DDP-resistant OSCC cells. The present study identified that miR-27b-3p was a target of OIP5-AS1. Furthermore, miR-27b-3p silencing reversed the effect of OIP5-AS1 knockdown on DDP sensitivity in DDP-resistant OSCC cells. TRIM14was shown to be a direct target of miR-27b-3p, and TRIM14 overexpression abolished the effect of miR-27b-3p on DDP sensitivity in DDP-resistant OSCC cells. The results suggested that OIP5-AS1 increased TRIM14 expression by sponging miR-27b-3p. In addition, OIP5-AS1 knockdown enhanced DDP sensitivity of OSCC in vivo. Data from the present study indicated that OIP5-AS1 may improve DDP resistance through theupregulationTRIM14 mediated bymiR-27b-3p, providing a possible therapeutic strategy for OSCC treatment.

MicroRNA-200b relieves LPS-induced inflammatory injury by targeting FUT4 in knee articular chondrocytes in vitro

xlomafota13 shared this article with you from Inoreader

Exp Ther Med. 2021 Apr;21(4):407. doi: 10.3892/etm.2021.9838. Epub 2021 Feb 25.

ABSTRACT

Osteoarthritis (OA), characterized by the degeneration of articular cartilage, is a major problem in aging populations, and cartilage chondrocytes have been indicated to serve a curial role in the progression of OA. MicroRNA-200b-3p (miR-200b) was preliminarily identified to participate in OA. However, its role and mechanism of action in injured chondrocytes in OA remain unclear to date. In the present study, lipopolysaccharide (LPS)-treated cells isolated from normal knee articular cartilage were used to mimic inflammatory injury of OA chondrocytes. Cell viability, apoptosis and inflammatory responses were detected using Cell Counting Kit-8, flow cytometry and enzyme-linked immunosorbent assay, respectively. The expression levels of miR-200b and fucosyltransferase-4 (FUT4) were measured by reverse transcription-quantitative PCR and western blottin g. The association between miR-200b and FUT4 was verified using TargetScan software, dual-luciferase reporter assay and RNA immunoprecipitation. The results indicated that LPS treatment decreased cell viability of primary chondrocytes, and increased apoptosis rate and production of IL-1β, IL-6 and TNF-α. The expression level of miR-200b was downregulated, and that of FUT4 was upregulated in OA cartilage tissues and LPS-treated normal chondrocytes compared with normal cartilage tissues and chondrocytes. Overexpression of miR-200b via transfection with miR-200b mimic inhibited the apoptosis rate and reduced the levels of IL-1β, IL-6 and TNF-α in LPS-stimulated chondrocytes. However, the suppressive effect of miR-200b overexpression on the LPS-induced inflammatory injury in chondrocytes was reversed by the restoration of FUT4 levels. Notably, FUT4 was indicated to be a downstream target of miR-200b and was negatively regulated by miR-200b. Taken together, the results of the current study indicated that miR-200b protected chondrocytes from LPS-induced inflammatory injury in vitro by targeting FUT4. These findings revealed the miR-200b/FUT4 axis as a potential candidate to target the degeneration of cartilages, thereby inhibiting the progression of OA.
