AIM: To study the effects of blunt trauma of eye on visual acuity and retinal nerve fiber layer (RNFL). METHODS: A prospective observational study was done on the patients of a road traffic accident (RTA) having blunt trauma injury of the eye from august 2018 to July 2019 at the Department of Ophthalmology, Hind Institute of Medical Sciences, Barabanki. Patients between the age group of 20 to 65 years undergoing RTA with ocular complaints were included in this study. Colour vision, contrast sensitivity, and best-corrected visual acuity (BCVA) were recorded, RNFL analysis was done through OCT. RESULTS: A total of 108 patients were enrolled in this study and were grouped as 54 cases and 54 controls. The mean age was 43±2.3 years with 11 (20.37%) females and 43 (79.6%) males in the case group. At initial visit after RTA, the difference between color vision, contrast sensitivity and BCVA between right and left eyes of cases and controls were significant. After a follow up of 3mo only significant difference was noted in contrast sensitivity between cases and control groups. Change in color vision and BCVA after 3mo was insignificant. Similarly, an initial significant difference was noted in mean RNFL thickness between cases and control groups, but after follow up of 3mo mean RNFL thickness difference was significant only in superior and temporal quadrants. CONCLUSION: RTA or blunt trauma of eye can lead to persistent RNFL thinning and decreased visual function.

Purpose: To examine the static and dynamic pupillary functions with automated pupillography in multiple sclerosis (MS) patients with preserved visual acuity. Methods: Forty-seven MS patients with preserved visual acuity were included in the study group and 43 healthy volunteers in the control group. The visual evoked potential of the patients was obtained. After routine ophthalmologic examination contrast sensitivity and the retinal nerve fiber layer (RNFL) thickness were measured. Finally scotopic, mesopic, and photopic pupillographies followed by dynamic pupillography were undertaken, and the pupillary dilatation speed was calculated. Results: The contrast sensitivity and RNFL thickness of the MS group were significantly lower than those of the control group ( p < 0.05; for both). In the MS and control groups, the scotopic pupil diameters were 5.48 ± 1.03 and 5.28 ± 0.78 mm, mesopic pupil diameters were 4.82 ± 0.83 and 4.48 ± 0.70 mm, and photopic pupil diameters were 3.84 ± 0.79 and 3.42 ± 0.49 mm, respectively ( p = 0.315, p = 0.044, and p = 0.004, respectively). In dynamic pupillography, the pupil in the MS group was more dilated than control group at all time sections examined except the sixth second ( p < 0.05; for all). Although the mean pupillary dilation speed in the first second was higher in the MS group ( p = 0.044), there was no significant difference between the groups for the other time intervals examined ( p > 0.05; for all). There was no correlation between pupillary parameters and P100-wave latency, RNFL thickness, or contrast sensitivity ( p > 0.05; for all). Conclusions: Static and dynamic pupillary functions may be affected in MS patients with preserved visual acuity. Although scotopic pupillary functions are preserved, mesopic, and photopic pupil functions are weakened.

We conducted a long-term follow-up (median, 10.5 years) of patients included in a randomized trial of levamisole versus placebo as surgical adjuvant therapy in 203 patients with malignant melanoma. Of the patients randomized, 104 received levamisole, and 99 received placebo. The results show that there is no difference between the treatment and control groups with regard to any of the three end points analyzed. These included disease-free interval, time to appearance of visceral metastasis, and survival. Moreover, there was no significant difference between the treatment and control groups after adjusting for age, sex, or stage of disease.

This study examines how piano-accompanied solfège reading practices of preservice music teachers ( N = 28) affect their performance on their musical hearing, reading, and writing (MHRW) classes. A pretest–posttest design with control groups was employed. The data were analyzed by 2 × 2 split-plot analysis of variance (ANOVA) and one-way ANOVA. Consequently, a significant difference was not found between the MHRW performance scores of the experimental and control groups. An analysis of mean performance scores revealed that the scores received by the control group were higher than those of the experimental group after the practice. Follow-up interviews that were held with 14 students after the experimental implementation revealed that students believed piano-accompanied courses were more useful, and they felt more comfortable with piano accompaniment. Although MHRW performance scores indicated that piano-accompanied solfège reading practices did not have a significant effect on preservice music teachers’ MHRW performances, it helped them participate in courses more enthusiastically.

Abstract Purpose Peripheral neuropathy is a complication of taxane that in severe cases can limit the optimal treatment. The aim of this study was to evaluate the efficacy of memantine in prevention of docetaxel induced peripheral neuropathy in patients with breast cancer. Methods In this randomized clinical trial, 40 women between the ages of 18 and 64 years with non-metastatic breast cancer (stages I to III) were included (registry number: IRCT20160310026998N9 and registry date: 26 March 2019). All patients were treated with the AC-T regimen (with docetaxel). Patients in intervention group received memantine at a dose of 20 mg for 8 weeks at the beginning of the first cycle of docetaxel. Patients in control group did not take any medication for neuropathy prevention. To assess the neuropathy, DN4 and CTCAE questionnaires were used at baseline, one months, three months and six months after the intervention. Results The DN4 questionnaire score was remarkably less in memantine group in follow up one (p-value: 0.033) and three (p < 00.1). The CTCAE follow up score did not change during study. The Neuropathy duration and Neuropathy onset, were shown significant difference between the intervention and control groups, p = 0.050 and p = 0.001, respectively. From 40 patients, 8 (40%) in memantine group and 2 (10%) in control group, did not experience any kind of neuropathy. Conclusion Data showed that prophylactic administration of memantine 20 mg/day has been effective in prevention of severity and incidence of docetaxel induced neuropathy in patients with breast cancer.

Introduction. Deprivation of parents might decrease self-esteem (SE) and result in affective and social incompatibility. In this randomized control trial, we examined the effect of aerobics exercise on SE among female adolescents living with no natural family.Materials and Methods. The sample consisted of all female adolescents aged 13 to 19 years (n: 72) who were covered by Isfahan Welfare organization. Participants were assigned into intervention and control groups by matched random sampling. Intervention included 8 weeks of aerobics exercise. Coppersmith SE inventory was administered before and after intervention as well as after one month follow-up.Results. No significant difference was seen between pre-SE scores of intervention(32.7±8.4)and control(33.0±6.7)groups (t=.16,P=.87). A significant difference was obtained in post-SE scores (40.2±5.7versus34.7±6.8,t=3.58,P=.001) and in one month follow-up scores (36.4±5.2versus33.0±5.2,t=2.25,P=.03).Discussion. The results demonstrated a low level of pre-SE in both groups. However, a significant improvement was seen in posttest of intervention group which persisted even one month after intervention. It supports the use of aerobics for female adolescents deprived from family life.

Background: We evaluated clinical outcome in relation to the degree of reperfusion in ESCAPE-NA1 trial. Methods: ESCAPE-NA1 was a multicenter, international randomized trial assessing the efficacy of nerinetide in ischemic stroke patients who underwent EVT within 12h from onset. Independent clinical outcome [90-days modified Rankin Scale (mRS) 0-2], excellent clinical outcome (90-days mRS 0-1), isolated subarachnoid hemorrhage with no parenchymal hemorrhage (iSAH) or symptomatic hemorrhage (sICH) on follow-up imaging, and death were compared between a treatment group and control group with respect to the level of reperfusion defined as mTICI. Univariable and multivariable logistic regression analyses were performed. Results: Data from 1090 patients were assessed. The occlusion locations were terminal ICA (18.3%), M1 MCA (61.8%,) M2 MCA (15.1%), other - e.g. M3 (3.7%). Final mTICI 0-1 was achieved in 5.5% of patients, mTICI 2a in 7.5%, mTICI 2b in 40.8%, mTICI 2c in 26.6% and mTICI 3 in 19.5%. Isolated SAH was present in 1.7% and sICH in 3%. There was no significant difference between the nerinetide and control groups in the reperfusion grade, presence of iSAH or sICH, or in clinical outcome. Odds of independent outcomes (mRS 0-2) and odds of excellent outcome (mRS 0-1) were significantly increasing with each improved reperfusion grade, Table 1. Sixty percent of patients with final mTICI 2b, 70% with mTICI 2c and 69% with mTICI 3 achieved good clinical outcome in comparison to 30% of patients with mTICI 0-2a. The incidence of iSAH was significantly lower in the NA1 arm (OR 0.28, 95%CI: 0.09-0.86, p=.027) adjusting for reperfusion status. Conclusion: Degrees of better reperfusion are strongly associated with better outcomes and reduced mortality. mTICI 2c-3 reperfusion should be a standard goal of EVT.

BACKGROUND Despite the availability and accessibility of free Pap smear test as a screening tool for cervical cancer, the rate of Pap smear test uptake remains unchanged over the last 15 years in Malaysia. High coverage of Pap smear uptake is shown to improve mortality rate. Furthermore, factors that contributed to low Pap smear uptake in Malaysia were beyond individual factors and the use of mobile technology could help to improve Pap smear uptake. However, there is lack of intervention studies that go beyond the individual factors and evaluate the use of mobile technology particularly WhatsApp application. OBJECTIVE The study aims to determine the effect of theory-based educational intervention and WhatsApp follow up to improve Pap smear uptake among post-natal women in a district in Malaysia. METHODS This is a two-armed, parallel single-blind cluster randomized controlled study among post-natal women in Seremban District. Twelve health clinics were randomly allocated to be in the intervention and control groups with a ratio of 1:1. This two phase intervention module was developed using Social Cognitive Theory and was delivered via face-to-face in the first phase and WhatsApp follow up in the second phase. Participants were follow-up at immediate, 4 weeks-, 8 weeks- and 12 weeks post-intervention. Primary outcome was Pap smear uptake and secondary outcomes include scores of knowledge, attitude and self-efficacy for Pap smear screening and intention to adhere to Pap smear practice. The data was analysed using IBM Statistical Package for Social Science (SPSS) version 25 and generalized mixed model was used to determine the effectiveness the intervention. α value will be set at below 0.05. RESULTS A total of 401 post-natal women were recruited with total response rate of 82.5%. There was a significant difference between the intervention and control groups in the Pap smear uptake (F(4,1178) = 3.222, p = <0.001), knowledge scores (F(4, 1172) = 14.946, p = <0.001), attitude scores (F(4, 1172) = 24.417, p = <0.001) and self-efficacy scores (F(1, 1172) = 10.432, p = <0.001). However, no significant difference in the intention to adhere to Pap smear practice between the intervention and the control groups (F(4, 1180) = 0.878, p = 0.476). CONCLUSIONS This study shows that Social Cognitive Theory-based intervention and WhatsApp follow up is an effective intervention for improving the Pap smear uptake among post-natal women in Seremban District in Malaysia. This intervention module can be tested in other women’s population to evaluate the effect of this theory and WhatsApp follow up on the Pap smear uptake.

scholarly journals Decision-making is the process of analyzing information about a problem situation and comparing it to a specific conclusion in order to solve a specific problematic (Yıkılmaz, 2001; Miller and Byrnes, 2001). Decision-making styles are a mechanism that is influenced by the internal and external conditions that determine the direction of the decisions of the individual, the content of the decision-making process, and the outcome of the decision-making process (Payne, Bettman and Johson, 1993; Bavol’ár and Orosová, 2015). ACT is a contemporary member of the Cognitive Behavioral Therapy family. ACT (Acceptance and commitment therapy) has both similar and different directions with Behavioral Therapies and Cognitive Therapies (Herbet and Forman, 2011; Hayes, 2004). KKT responds to classical behavioral treatments using both existential and cognitive approaches in the analysis of behavior. KKT is a science wing that tries to solve human problems with a wider perspective aimed at solving problematic human behaviors (Plumb, Stewart, Dahl and Lundgren, 2009). It is seen that there is very little research about the new approach of ACT approach when the aiming country of our country is screened and it is thought that our country will contribute to the field of psychological counseling with the work done. In the scope of the research, experimental and control groups and preliminary test, post-test and follow-up measurements of 2x3 experimental design were used. The study's study group consists of a total of 24 (12 experimental and 12 control groups) university students studying in different departments and levels, continuing their education in the academic year of 2015-2016 in Ağrı province and İbrahim Chechen University in 2015-2016 academic year. The average age of participants in the experiment and control group is 20. There were 12 participants in the experimental group, 7 female and 5 male, and 12 participants, 7 female and 5 male in the control group. Personal Information Form and Decision Making Style Scale prepared by the researcher were used in the research. In order to decide on the tests to be used in the course of analyzing the data, the scores of the participant's Decision Styles Scale pre-test, which are placed primarily in the experimental and control groups, it was analyzed whether the basic expectations of parametric tests were answered. As a result of the analysis made, the scores, skewness and kurtosis coefficients obtained from the Decision Making Styles Scale were given to the experimental and control groups. It was determined that the distribution was normal in the result of Shapiro-Wilk test, in which the skewness and kurtosis coefficients of each sub-scale were ranked between -1 and +1. Participants in the experimental and control groups; homogeneity test results for decision-style pre-test measurements indicate that the data are homogeneous. According to the results of the Mauchly Globalness Test, it has been determined that working supports the hypothesis. It was determined that there was no significant difference between the pre-test scores obtained from dependent decision-making style of experiment and control groups, but the test group showed lower mean scores at the significant level within the scores of post-test and follow-up tests. Therefore, it can be said that the ACT-oriented psychoeducation program applied to the experimental group reduces the dependent decision-making style scores from the decision style sub-dimensions and the psychoeducation program has a lasting effect. It was determined that there was no significant difference between pre-test, post-test and follow-up scores obtained from the Spontaneous-Instant Decision Style of experiment and control groups. Thus, it can be said that this situation does not cause a significant difference in the Spontaneous-Decision-Making Style scores from the decision style sub-dimensions of the ACT-oriented psychoeducation program applied to the experimental group. The ACT -oriented psychoeducation program had a decline in the intuitive decision-making styles of the individuals, but this decrease did not create significant differences. Thus, it can be said that this situation does not make a meaningful difference in the intuitive decision style scores from the decision style sub-dimensions of the KKT oriented psychoeducation program applied to the experimental group. The pre-test scores obtained from the rational decision-making style of the experimental and control groups showed that there was a difference between the post-test and the follow-up scores, but this difference was not significant. As a result of the analysis, it was determined that the test group had higher levels of rational decision style than the pre - test scores in the post test and follow - up scores, whereas the post test and follow - up test scores in the control group rational decision style showed a decrease compared to the pre - test scores. the pre - test scores. Decision-making Styles Scale Avoidant Decision Making As a result of the analysis of the mean scores of the subscale scores of pre-test, post-test and follow-up measures, the group effect was found to be insignificant. It was determined that the experimental and control groups differed significantly from the pre-test scores obtained from the avoidant decision-making style but did not show any significant change within the scores of the post-test and follow-up tests.

Background. To evaluate the efficacy and acceptability of orthokeratology for slowing myopic progression in children with a well conducted evidence-based analysis.Design. Meta-analysis.Participants. Children from previously reported comparative studies were treated by orthokeratology versus control.Methods. A systematic literature retrieval was conducted in MEDLINE, EMBASE, Cochrane Library, World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. The included studies were subjected to meta-analysis using Stata version 10.1.Main Outcome Measures. Axial length change (efficacy) and dropout rates (acceptability) during 2-year follow-up.Results. Eight studies involving 769 subjects were included. At 2-year follow-up, a statistically significant difference was observed in axial length change between the orthokeratology and control groups, with a weighted mean difference (WMD) of −0.25 mm (95% CI, −0.30 to −0.21). The pooled myopic control rate declined with time, with 55, 51, 51, and 41% obtained after 6, 12, 18, and 24 months of treatment, respectively. No statistically significant difference was obtained for dropout rates between the orthokeratology and control groups at 2-year follow-up (OR, 0.79; 95% CI, 0.52 to 1.22).Conclusions. Orthokeratology is effective and acceptable for slowing myopic progression in children with careful education and monitoring.

Abstract Background Evaluation of the three currently most common techniques for intraocular lens (IOL) sclera fixation: (1) Prolene suture with Hoffman sclera pocket (2) four-point GoreTex suture technique (3) sutureless flanged intrascleral IOL fixation with double-needle (“Yamane”) technique. Material and Methods Retrospective, clinical case series (chart review) at the Department of Ophthalmology, Ludwig-Maximilians-University (LMU), Munich, Germany. Enrolled in the study were 51 patients with 55 eyes. Best-corrected visual acuity (BCVA); manifest refraction (OR); corneal tomography (central corneal thickness, CCT); biometry; central macular thickness (CMT) by optical coherence tomography (OCT); intraocular pressure (IOP); and IOL type and IOL power were recorded and compared prior to and 3 – 12 months post IOL sclera fixation surgery. Pre- and postsurgery difference analysis was performed by Wilcoxon rank sum testing (z). Results Intrascleral fixation by GoreTex suture was performed in 14 (25.5%) eyes, by Prolene suture in 19 (34.5%,) and by Yamane technique in 22 (40.0%) eyes. Within the 3 – 12 months follow-up post scleral fixation, a total of 2 (14.3%) eyes from the GoreTex, 3 (15.8%) from the Prolene and 1 (4.5%) eye from the Yamane group required refixation. Pre- and post-surgery analysis revealed a statistically significant difference in the total patient population BCVA (exact Wilcoxon test: z = − 3.202; p = 0.001; n = 55) and the Yamane subgroup (exact Wilcoxon test: z = − 2.068; p = 0.001; n = 22). The GoreTex (n = 14) and Prolene (n = 19) subgroups revealed no statistically significant differences versus preoperative baseline. Across groups, there was no statistically significant difference in IOP, CMT, and CCT. No retinal complications were observed, neither intraoperatively nor during follow-up. Conclusion The volume of IOL revision surgery is increasing. Often, the only option left for visual rehabilitation is scleral IOL fixation. All three scleral fixation techniques studied demonstrated a good safety profile with no statistically significant impact on IOP, CMT, CCT, but with a notable revision rate. Visual rehabilitation to preoperative baseline levels (GoreTex [n = 14] and Prolene [n = 19]) and a statistically significant increase in visual acuity (total cohort [n = 55] and Yamane [n = 22]) seems possible. Unlike iris fixation, scleral fixation is surgically more complex and the surgeon must master a steeper learning curve.
