Corrosive burns lead to progressive esophageal stricture and dysphagia. There are many trials to prevent Esophageal stricture formation after corrosive burn. This study aimed to access the effects of EW-7197 on prevention for esophageal stricture formation after corrosive esophageal burn. animal study were classified divided into three groups: a healthy group, a control group (corrosive burn without EW-7197), and a treatment group (corrosive burn with EW-7197). Corrosive esophageal burns were produced using 30% NaOH on the lower esophagus. For 3 weeks, the control group received vehicle and the treatment group received 20 mg/kg/day EW-7197. Treatment efficacy was assessed by measuring the stenosis ratio by esophagogram with contrast media on day 21. histologic staining was performed to evaluate the fibrosis area ratio, and western blotting was performed to evaluate fibrotic markers. Among 20 rats that underwent surgery, 14 survived. Three in the treatment group died because of esophageal perforation, and three in the control group died due to their debilitating status. The esophageal stenosis ratio was significantly lower in the treatment group than in the control group (12.1 ± 9.5% and 42.2 ± 8.3%, respectively; p = 0.001). The histologic fibrosis area ratio was also significantly lower in the treatment group (12.5 ± 3.0% and 21.6 ± 2.1%, respectively; p = 0.001). The treatment group showed lower expressions of profibrogenic proteins such as TGF-β1, pSmad3, and α-SMA. EW-7197 may be a good alternative for the prevention esophageal stricture formation after corrosive burn.

Corrosive burns lead to progressive esophageal stricture and dysphagia. There are many trials to prevent esophageal stricture formation after corrosive burn. EW-7197 has been proven in several animal models of fibrosis to have antifibrotic and antiproliferative effect. This study aimed to assess the effects of EW-7197 on prevention for esophageal stricture formation after corrosive esophageal burn. An animal study was carried out, where the animals were divided into three groups: a healthy group, a control group (corrosive burn without EW-7197), and a treatment group (corrosive burn with EW-7197). Corrosive esophageal burns were induced using 30% NaOH on the lower esophagus. For 3 weeks, the control group received vehicle and the treatment group received 20 mg/kg/day EW-7197. Treatment efficacy was assessed by measuring the stenosis ratio by esophagogram with contrast media on day 21.

BACKGROUND: The growing number of COVID-19 patients with long-lasting olfactory disorders makes it necessary to identify effective treatments that enhance the spontaneous recovery of olfactory function. METHODS: Multicentre randomised case-control study that involved 18 patients with COVID-19 related anosmia or severe hyposmia for more than 30 days. Nine patients were prescribed systemic prednisone and nasal irrigation with betamethasone, ambroxol and rinazine for 15 days. The other 9, untreated, patients were used as controls. The olfactory function was evaluated with CCCRC test at 20 and 40 days from the first evaluation. RESULTS: In the control group, a median olfactory score of 20 (IQR 30) was detected at baseline. At the 20-day control there was no significant improvement in olfactory function. The improvement in olfactory performance became significant at the 40-day follow-up compared to baseline scores [60 (IQR 60) versus 20 (IQR 30)]. In the treatment group, patients had a mean olfactory score of 10 (IQR 15) at initial control. At the 20-day control, a significant im-provement in the olfactory scores, compared to the baseline, was detected [70 (IQR 40) versus 10 (IQR 15)]. Olfactory function further improved at 40 days [median score 90 (IQR 50)]. Patients in the treatment group reported significantly higher improvements of the olfactory scores than the controls at both the 20-day [40 (IQR 45) versus 10 (IQR 15)] and 40-day [60 (IQR 40) versus 30 (IQR 25)] evaluations. CONCLUSIONS: Based on the results of this study, the mix of drugs including steroids could represent a useful specific therapy to reduce the prevalence of this long-term morbidity.

Abstract Both silicone gel and quercetin are effective in scar treatment but have different action mechanisms. Quercetin is mainly applied in the gel form and can lead to poor adhesion of silicone gel sheet; therefore, they cannot be combined in clinical use. In this study, a silicone gel sheet that releases quercetin in a sustained manner for 48 hours was successfully developed. Four round scars (Ø: 1 cm) were made in the ears of New-Zealand albino rabbits (n=10). After scar healing, the rabbits were divided into four groups: blank control group with no treatment, silicone gel sheet group with dressing change every 2 days, quercetin group with dressing change 3 times daily, and combination treatment group with dressing change every 2 days. Scar assessment was performed 3 months later. Transepidermal water loss showed no difference between the combination treatment group and the silicone gel sheet group, but was lower than that in the quercetin group and the blank control group. Immunohistochemistry of CD 31 and proliferating cell nuclear antigen showed the following results: combination treatment group < silicone gel sheet group = quercetin group < blank control group. Polymerase chain reaction results showed that the expression of type-I and type-III collagen in the combination treatment group and the quercetin group was significantly lower than that in the other two groups. Thus, quercetin-modified silicone gel sheet combines the advantages of the two treatments and is more effective at inhibiting cell proliferation in scar tissue than either of the two treatments alone.

This pilot study aimed at assessing the feasibility of capturing physiological evidence of reduced stress for hospitalized children following expressive arts therapy. Twenty-five patients were offered a novel form of expressive arts therapy, termed Healing Sock Creatures, during their stay in the hospital. Saliva samples were collected at two times in the afternoon for the purpose of measuring salivary cortisol levels. The patients were randomly assigned to two groups, a treatment group or a wait-list control group. A trend of decreased cortisol levels was apparent following therapy in the treatment group and concurrent steroid treatment, which is common in intensive care units, does not appear to interfere with the ability to measure decreased cortisol levels following therapy. Our results support the design of a formal study to assess physiological biomarkers of stress in hospital settings. To our knowledge, this is the first in-patient study assessing a biomarker of stress following expressive arts therapy for children

AbstractThe present study explores the effects of recast plus form-focused instruction and form-focused instruction on vocabulary development and the mediating effect of working memory. Sixty-six university students were assigned to a recast plus form-focused instruction (FFI) group, a FFI group, and a control group. The instructor provided recasts on non-target vocabulary items in the recast plus FFI group, whereas the FFI group completed two form-focused vocabulary tasks only. Pretests, posttests, and delayed posttests were administered to examine learners’ development of target vocabulary items. A reading span test was employed to examine learners’ complex working memory capacities. Results show that the recast plus FFI group exhibited superior performance over the control group on both posttests and delayed posttests with large effect sizes. Working memory did not significantly correlate with vocabulary development in either treatment group.

Objective. Evaluate the effects of carboxy-methyl-beta-glucan on cervical epithelialization and on the vaginal microbiota in patients with HPV infection or low-grade cervical preneoplastic lesion (CIN 1). Materials and Methods. Seven-hundred eighty-four women with positive HPV tests or diagnosed with CIN 1 were enrolled in a retrospective case-control study. All the recruited women performed, at baseline and after 6 months, Pap test, HPV test, evaluation of vaginal health according to the Amsel criteria, colposcopy, and punch biopsy. The study population was then divided into 2 groups in relation to the therapy performed during the follow-up period. Group A performed treatment with vaginal gel based on carboxy-methyl-beta-glucan (1 application/day for 20 days per month for 3 months). Group B was the control group. Results. The patients of group A had a significant improvement in the ectopia pattern and a greater number of cases with metaplasia in the maturation phase with a significant increase in Lugol uptake. In the experimental group, a significant improvement in the pH indices, a negative Swift test and a resolution of the leucorrhoea were observed. A negative result of the 37.1% Pap test and the 39.9% HPV test (vs. 15.2% and 16.5%, respectively) were demonstrated in the treatment group with respect to the control group. A negativization of the colposcopic pictures was observed with a reduction in the amount of CIN 1 found higher in the treatment group. Conclusions. Vaginal therapy based on carboxy-methyl-beta-glucan has been able to improve overall vaginal health; this effect seemed to positively impact the risk of persistence and progression of CIN.

This experiment was conducted to determine the effect of papaya leaf (Carica papaya) and kalo jeera (Nigella sativa) seeds powdered supplementation in drinking water as a growth promoter in broiler chickens. A total of 20 Cobb-500 broiler chicks (day-old) were purchased from local hatchery (Nourish Poultry and Hatchery Ltd.) and after seven days of acclimatization chicks were randomly divided into two groups, A (n=10) and B (n=10). The group A was kept as a control and not treated. The group B was supplemented with papaya leaf and kalo jeera powder with feed and water. Weekly observations were recorded for live body weight gain up to 5th weeks and hematological tests were performed at 35th day’s age of broiler to search for hematological changes between control (A) and treatment (B) groups. The initial body weight of groups A and B on 1st were 41.00±0.56 gm and 41.50±0.35 gm, respectively and after 35th day of experiment final body weight were 1470±57.35 gm and 1720±58.56 gm, respectively and economics of production were analyzed and found that net profit per broiler was Tk. 8.91 and Tk. 20.69, respectively. The treatment group B was recorded statistically significant (at 1% level) increased (17.00%) for live body weight than that of control group A. The hematological parameters total erythrocyte count (TEC), erythrocyte sedimentation rate (ESR) and hemoglobin (Hb) estimation value of treatment group shows significant difference, while hemoglobin estimation does not show significant difference from control group. The results suggest that better growth performance could be achieved in broilers supplemented with papaya leaf and kalo jeera seeds.

<p>The current study focuses on the importance of integrating peer- and self-assessment in<br />teaching English as a second/foreign language in Saudi Arabia. It pays special attention to the<br />mechanisms by which Saudi EFL learners can improve their English writing skills if they<br />engage in peer- and self-assessment regularly. To this end, the researcher administered a<br />writing composition task to measure the participants’ ability to express themselves in good<br />English, focusing on the coherence, cohesion, word choice, spelling, punctuation, and layout<br />of their essays. The researcher utilised the experimental two-groups design of a pre-test and a<br />post-test, in order to evaluate the participants’ performance prior to the application of the<br />treatment (i.e. peer- and self-assessment) and after it. For the purpose of the study, the<br />participants were divided into two groups: students in group A (i.e. the treatment group)<br />engaged in peer- and self-assessment regularly throughout the term, whilst students in group<br />B (i.e. the control group) did not. The results of group A on the pre-test and post-test were<br />compared to those of group B to determine whether the treatment had any impact on their<br />performance. The results reveal that group A outperformed their group B counterparts on the<br />post-test. The statistical analysis demonstrates that the difference between the results of the<br />two groups was statistically significant, suggesting that the treatment contributed positively to<br />the performance of the treatment group. Finally, the study concludes with recommendations<br />for further research.</p>

Nursing staffs from two long-term care facilities attended a multisession educational program about the care of residents with diabetes (treatment group). A control group consisted of the nursing staffs from two other similar facilities who did not participate in the educational program. Both groups were given a knowledge pretest and posttest. A chart review also was conducted following the educational intervention to determine any changes in the diabetes care provided by the treatment group. Following the educational program, the treatment group had a significant increase in their mean score on the knowledge test compared with the control group. However, a. review of the residents' charts revealed no significant increases in specific behaviors related to diabetes care. The findings suggest that, in addition to educational programs, more focused training concerning diabetes care is needed to improve the care of residents with diabetes in long-term care facilities. Implications for diabetes educators are discussed.
