Instructors and students identify communication skills as being essential to successful classroom teaching and student learning. This study investigates the stability of student evaluations with respect to items related to instructor’s clarity. The majority of student evaluations completed at the end of a semester at the college level contain a question directly related to clarity. A pilot study was conducted which utilized four finite mathematics courses being taught by the same instructor. After assessing reliability and validity, a follow-up study was conducted utilizing four sections of introductory statistics employing the same design as the pilot. Ninety-four students completed some component of the researcher-constructed evaluation resulting in an overall 96% response rate. Seventy-one students completed the entire evaluation, allowing for a comparison between the high inference and the low-to-moderate inference items used to measure instructor’s clarity, resulting in a useable response rate of 72%. After a statistical transformation of the high inference item, descriptive statistics were produced for each type of item. Through a t-test, a statistically significant difference was found between the high and low-to-moderate clarity items. The difference between the types of clarity ratings was then analyzed via ANOVA techniques to explore differences by gender and expected course grade. Males tended to rate the instructor inconsistently, assigning lower ratings for the low-to-moderate inference items, while other ratings appear to demonstrate consistency.

The purpose of this study is to explore the stability and interaction between parental pressure and social research report, as well as the role of employment status and family income levels in this process. This study used a special study on Korean children (PSKC) 2–4 waves. Use t-test, correlation and autoregressive cross-delay modeling to analyze the data. The main findings of this study are: First, over time, parental pressure and mother’s social research report are consistent. Secondly, the pressure of motherhood and childcare has an obvious lagging effect on upbringing, and vice versa. Third, there is no significant difference between working mothers and non-working mothers in terms of the stability of working parents' pressure, social research report and social research report for children's pressure channels. However, parental pressure can only predict the social research report of working mothers. Fourth, there is no significant difference between the stability and interaction of these two structures in household income levels. In short, the results show that, over time, parental pressure is consistent with mother’s social research report. The results also show that there is a significant cross-lag effect between the mothers’ perceptions of mutual pressure analysis. In the process from parental pressure to social research report, I found the difference between working and non-working mothers. The advantage of this study is that the expected longitudinal design was adopted during infancy and the priority between the two structures can be considered. The results of this study can be used as a source of intervention plans to help parents withstand severe parenting pressure and lack of social research report.

Background:Gender differences in prevalence and disease course are known in various rheumatic diseases; however, investigations of gender difference concerning therapeutical response have yielded variable results.Objectives:The aim of this retrospective study was to investigate, whether a gender difference in response rate to biological disease-modifying antirheumatic drugs (bDMARDs) and apremilast in bDMARD-naïve patients could be observed across the three most prevalent inflammatory arthritis diseases: rheumatoid arthritis (RA), spondylarthritis (SpA) and psoriatic arthritis (PsA). Additionally, a response to individual TNF blockers was investigated in this respect.Methods:Data from bDMARD-naïve RA-, SpA- and PsA-patients from Bioreg, the Austrian registry for biological DMARDs in rheumatic diseases, were used. Patients with a baseline (Visit 1=V1) and follow-up visits at 6 months (Visit 2=V2) and 12 months (Visit 3=V3) were included and response to therapy with TNF-inhibitors (TNFi), furthermore to therapy with rituximab, tocilizumab and apremilast was analyzed according to gender. The remaining bDMARDs were not analyzed due to small numbers. Key response-parameter for RA was disease activity score (DAS28), whereas for PsoA the Stockerau Activity Score for Psoriatic Arthritis (SASPA) and for SpA the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were employed; in addition, the Health assessment Questionnaire (HAQ) was used. Data were analyzed in R Statistic stratified by gender using Kruskal-Wallis and Wilcoxon tests.Results:354 women and 123 men with RA (n=477), 81 women and 69 men with PsA (n=150), 121 women and 191 men with SpA (n=312) were included. No significant differences in biometrics was seen between female and male patients at baseline in all diseases.In RA patients overall DAS28 decreased from baseline (V1) to V2 and V3 (DAS28: V1: male: 4.38 [3.66, 5.11], female: 4.30 [3.68, 5.03], p(m/f) = 0.905; V2: male: 2.66 [1.73, 3.63], female: 3.10 [2.17, 3.98], p(m/f) = 0.015; V3: male: 2.25 [1.39, 3.36], female: 3.01 [1.87, 3.87], p(m/f) = 0.002). For TNF inhibitors (n=311), there was a significant difference between genders at V2 (Fig.1a). Patients receiving Rituximab (n=41) displayed a significantly higher DAS28 at baseline in females, which diminished in the follow up: V1: (p(m/f) p=0.002; V2: p=0.019; V3: p=0.13); response to tocilizumab (n=63) did not show any gender differences.In PsA patients overall SASPA decreased from baseline (V1) to V2 and V3 (SASPA: V1: male: 4.00 [2.80, 5.20], female: 4.40 [2.80, 5.80], p(m/f) = 0.399; V2: male: 2.20 [1.20, 3.50], female: 3.40 [2.00, 5.00], p(m/f) = 0.071; V3: male: 1.80 [0.80, 2.70], female: 3.01 [2.35, 4.80], p(m/f) = 0.001). For TNF inhibitors (n=79), there was a significant difference between genders at V3 (Fig 1a). For Apremilast (n=39), there was a significant difference between genders at V2 (Fig.1c).In SpA patients overall BASDAI decreased from baseline (V1) to V2 and V3 (BASDAI: V1: male: 4.70 [2.88, 6.18], female: 4.80 [3.30, 6.20], p(m/f) = 0.463; V2: male: 3.05 [2.00, 4.60], female: 3.64 [2.62, 5.41], p(m/f) = 0.039; V3: male: 3.02 [1.67, 4.20], female: 3.65 [2.18, 5.47], p(m/f) = 0.016). In V3 a differential BASDAI in response to TNFi (n=299) was observed (Fig.1a).Possible differences of response to individual TNFi (etanercept, infliximab, other TNFi) measured by HAQ were investigated in all diseases together. The difference between male and females was significant at baseline for all 3 TNFi; whereas with the use of ETA the significant difference was carried through to V2 and V3, it was lost with the use of IFX and was variable with the other TNFi (Fig.1b)Figure 1.Conclusion:Female patients showed a statistically lower response to TNFi in all three disease entities (RA, SpA and PsoA) to a variable degree in our homogenous central european population. Interestingly, the difference was not uniform across individual TNFi when measured by HAQ. Gender differences were also seen in response to Apremilast.Disclosure of Interests:Elisabeth Loibner: None declared, Valentin Ritschl: None declared, Burkhard Leeb Speakers bureau: AbbVie, Roche, MSD, Pfizer, Actiopharm, Boehringer-Ingelheim, Kwizda, Celgene, Sandoz, Grünenthal, Eli-Lilly, Grant/research support from: TRB, Roche, Consultancies: AbbVie, Amgen, Roche, MSD, Pfizer, Celgene, Grünenthal, Kwizda, Eli-Lilly, Novartis, Sandoz;, Peter Spellitz: None declared, Gabriela Eichbauer-Sturm: None declared, Jochen Zwerina: None declared, Manfred Herold: None declared, Miriam Stetter: None declared, Rudolf Puchner Speakers bureau: AbbVie, BMS, Janssen, Kwizda, MSD, Pfizer, Celgene, Grünenthal, Eli-Lilly, Consultant of: AbbVie, Amgen, Pfizer, Celgene, Grünenthal, Eli-Lilly, Franz Singer: None declared, Ruth Fritsch-Stork: None declared

Background: blockade of the RAAS lowered the incidence of Diabetes Mellitus in randomized clinical trials, but whether the de-activation of the RAAS can elicit the same beneficial effect in patients with renovascular hypertension (RVH) is unknown. Aim: to verify if endovascular treatment (EVT) could improve glycemic control in patients with atherosclerotic RVH. Methods: in the METRAS study (http://clinicaltrials.gov/show/NCT01208714, a randomized clinical trial comparing the effect of EVT on top of optimal medical therapy versus medical therapy alone (OMT) on GFR of the ischemic and contralateral kidney in patients with atherosclerotic RVH), glycemic control, as assessed by HbA1c at baseline and repeatedly during follow-up, was a pre-specified secondary endpoint of the study. Results: between June 2010 and March 2014, 16 patients were randomly assigned to EVT plus optimal medical therapy (n = 9) or OMT alone (n = 7). At baseline the 2 groups showed no significant difference of age, clinical and demographical features. All the patients, except two in the EVT group, were on a RAAS blocker. At 2 years follow-up HbA1c increased in patients on OMT (59±12 mmol/mol) from baseline values (45±16 mmol/mol, p<0.001). By contrast, in the patients assigned to EVT HbA1c remained stable (42±7 mmol/mol at baseline vs 41±5 mmol/mol at follow-up; p = NS; p<0.001 vs OMT at follow-up). When analyzed after multivariate adjustment for age, HbA1c at enrollment, and presence/absence of DM, the difference between the arms remained highly significant (p<0.001). Conclusions: in patients with atherosclerotic RVH and chronic activation of the RAAS, deactivation of the RAAS by means of EVT was associated with no increase in plasma levels of HbA1c over long term follow-up. At variance, similar patients assigned to optimized medical therapy alone showed worsened glycemic control over time. These findings support the contention of a causative role of RAAS activation in the incidence/progression of DM.

OBJECTIVE: Perform radiographic analysis of the use of Transverse Traction Device (DTT) with respect to fusion rate in patients submitted to vertebral arthrodesis for degenerative lumbar diseases. METHODS: We selected x-ray images on anteroposterior, lateral and oblique views and with maximum flexion and extension dynamics of 23 patients submitted to posterolateral arthrodesis of the lumbar spine with a minimum follow-up period of six months. The images were evaluated and classified by the Linovitz's system by two spine surgeons. RESULTS: We evaluated the radiographs of 23 patients after the minimum postoperative period of 6 months and of these, 11 have used DTT. With regard to the consolidation rate, seven patients (63.6%) in the group of DTT were classified as fusion as well as six patients (50%) who were not submitted to the treatment. There was no statistical difference between the groups regarding the consolidation rate. CONCLUSION: The use of transverse traction device in this study showed no significant difference in the rate of consolidation in radiographic evaluation. Studies on the effective participation of this device in the stability of pedicle fixation systems are still lacking in the literature.

In this paper, a mathematical model with time-delay-related parameters and media coverage to describe the diffusion process of new products is proposed, in which the time-delay-related parameters denote the stage in which potential customers decide whether to adopt a new product. Then, the stability and the Hopf bifurcation of the proposed model are analyzed in detail. The center manifold theorem and the normal form theory are used to investigate the stability of the bifurcating periodic solution. Moreover, a numerical simulation is conducted to investigate the difference between the model with delay-dependent parameters and that with delay-independent parameters. The results show that there is significant difference between the two models.

<p class="abstract"><strong>Background:</strong> Plantar fasciitis (PF) is considered as degenerative tendinopathies. Repeated micro trauma is the major etiology of these diseases. Autologous platelet rich plasma (PRP) injections are becoming more popular in the treatment of enthesopathies like PF. The growth factors in PRP cause tissue healing. We compared the result of injecting intra-lesional autologous PRP injections versus steroid infiltration in chronic PF.</p><p class="abstract"><strong>Methods:</strong> A prospective, interventional and analytic comparative study was done and 81 patients (120 heels) were included in this study and were followed up for 6 months. We assessed the outcome of each patient using visual analog score (VAS) and foot and ankle disability index (FADI) on follow-up at 1, 3, and 6 months. <strong></strong></p><p class="abstract"><strong>Results:</strong> In our study, female preponderance was seen. Left side was more common as compared to right side. Unilateral PF is more common than bilateral. The difference with in the individual group at baseline and at 1,3 and 6 months was statistically highly significant in terms of VAS and FADI (p=0.0001) But the difference in the between the two groups was insignificant for VAS and FADI at 1, 3 and 6 months.</p><p class="abstract"><strong>Conclusions:</strong> In our study, as there is no significant difference in VAS and FADI score between corticosteroid injection group and PRP injection group at 1, 3 and 6 months follow up. So, it’s reasonable to conclude that both are equally effective in PF. But as PRP injection comes out to be more time consuming and more costly, corticosteroid seems to be more efficient, cost and time wise. Hence, the latter should be a better choice.      </p>

BACKGROUND: Axi-cel is an autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy that is approved for treatment of relapsed/refractory (R/R) large B-cell lymphoma and is associated with high response rates and durable remissions. Recent data show that axi-cel is effective across various adverse prognostic features, namely cell of origin, disease bulkiness, and extranodal disease, among others. Hypoalbuminemia is a known adverse prognostic factor in lymphomas. It is unknown if axi-cel overcomes the adverse prognostic feature of hypoalbuminemia in R/R large B-cell or transformed follicular lymphoma. METHODS: We conducted a retrospective analysis of patients treated with axi-cel across three Mayo Clinic campuses (Rochester, Jacksonville, and Phoenix) from 06/01/2018 until 04/01/2019. The primary objective of this analysis was to assess the impact of hypoalbuminemia (defined at day 0, prior to infusion) on outcome after axi-cel therapy. RESULTS: A total of 50 (male=37, 74%) patients (pts), median age of 53 (26-67) years received axi-cel. The median number of prior lines of therapy was 3 (2-8) (Table 1). Two pts had no available serum albumin levels at time of axi-cel infusion. Seven (15%) of 48 pts had serum albumin levels lower than 3.5 g/dL (median= 3.3 g/dL (range 2.6-3.4)) and the median follow up of survivors was 7.6 (1.9-14.3) months. The best overall response rate (ORR) and complete remission (CR) rates in these pts were 57% and 57%, respectively. One (14%) patient had stable disease and 2 (29%) had disease progression. The median overall survival (OS) for pts with hypoalbuminemia was not reached. On the other hand, 41 (85%) pts had a normal serum albumin level (median=4.0 (range 3.5-5.1) g/dL) and the median follow up for survivors was 6.3 months. The best objective response rate (ORR) and complete remission (CR) rates in these pts were 82% and 44%, respectively. The median OS for pts with normal serum albumin was 14 (95%CI=6.3-29.6) months. There was no significant difference at 6-months and 1-year OS between pts with hypoalbuminemia vs. those with normal baseline serum albumin levels [6-month=100% vs. 79%(95%CI=64-93%); 1-year (100% vs. 54% (95%CI=26-82%), p=0.17] (Figure 1). All grades cytokine release syndrome (CRS) was diagnosed in all 7 pts with hypoalbuminemia (100%) and in 38 of 41 (92%) pts without hypoalbuminemia. There was no difference in the median duration of CRS between pts with or without hypoalbuminemia [6 (range 1-11) days vs 5 (range 1-19) days, p=0.89]. Neurotoxicity (all grades) was observed in 5 (71%) pts with hypoalbuminemia compared 26 (63%) with normal albumin levels. There was no statistically significant difference in median duration of neurotoxicity between pts with hypoalbuminemia and those with normal baseline albumin levels [9 (range 1-10) days vs. 3 (range 0-25) days, p= 0.72]. CONCLUSIONS: Hypoalbuminemia does not have a significant impact on the outcomes of axi-cel therapy, including the incidence of CRS or neurotoxicity. These results need to be validated in a large collaborative multicenter study. Further investigation is needed to assess the prognostic impact of severe hypoalbuminemia (<3g/dL) on axi-cel therapy.

Abstract AimTo investigate the effect of orthokeratology (OK) lens on axial length (AL) elongation in myopia with anisometropia children.MethodsThirty-seven unilateral myopia (group 1) and fifty-nine bilateral myopia with anisometropia children were involved in this 1-year retrospective study. And bilateral myopia with anisometropia children were divided into group 2A (diopter of the lower SER eye under − 2.00D) and group 2B(diopter of the lower SER eye is equal or greater than − 2.00D). The change in AL were observed.The datas were analysed using SPSS 21.0.Results(1) In group 1, the mean baseline AL of the H eyes and L eye were 24.70 ± 0.89 mm and 23.55 ± 0.69 mm, respectively. In group 2A, the mean baseline AL of the H eyes and L eyes were 24.61 ± 0.84 mm and 24.00 ± 0.70 mm respectively. In group 2B, the mean baseline AL of the H eyes and L eyes were 25.28 ± 0.72 mm and 24.70 ± 0.74 mm. After 1 year, the change in AL of the L eyes was faster than the H eyes in group 1 and group 2A (all P<0.001).While the AL of the H eyes and L eyes had the same increased rate in group 2B. (2) The effect of controlling AL elongation of H eyes is consistent in three groups (P = 0.559).The effect of controlling AL elongation of L eyes in group 2B was better than that in group 1 and group 2A (P < 0.001). And the difference between group 1 and group 2A has no statistical significance. (3) The AL difference in H eyes and L eyes decreased from baseline 1.16 ± 0.55mm to 0.88 ± 0.68mm after 1 year in group 1.And in group 2A, the AL difference in H eyes and L eyes decreased from baseline 0.61 ± 0.34mm to 0.48 ± 0.28mm. There was statistically significant difference (all P<0.001). In group 2B, the baseline AL difference in H eyes and L eyes has no significant difference from that after 1 year (P = 0.069).ConclusionsMonocular OK lens is effective on suppression AL growth of the myopic eyes and reduce anisometropia value in unilateral myopic children. Binocular OK lenses only reduce anisometropia with the diopter of the low eye under − 2.00D. Binocular OK lenses cannot reduce anisometropia with the diopter of the low eye equal or greater than − 2.00D. Whether OK lens can reduce refractive anisometropia value is related to the spherical equivalent refractive of low refractive eye in bilateral myopia with anisometropia children after 1-year follow-up.

Abstract Background and Aims Different rituximab dosing schedules have been used to manage primary membranous nephropathy (PMN). Better response rate and toxicity needs to be balanced to arrive at correct dose. The dosing schedules in PMN as of now are an on the lines of the management of lymphoma or rheumatoid arthritis. In the current study, we report the 1-year outcome of patients treated with three dosing schedules of rituximab in PMN. Method The current report is a study of patient of PMN treated with three different dosing schedules of rituximab treatment. The study included PMN patients with nephrotic syndrome (proteinuria&gt;3.5 g/day and serum albumin of &lt; 3.5 g/dL). Patients with secondary membranous nephropathy and a history of prior exposure of immunosuppressive therapy in the last three months were excluded from the study. The three dosing schedules of rituximab were 1 g (on day 0,15) (regimen 1), 375 mg/m2 (weekly for four weeks) (regimen 2) or CD19 targeted rituximab therapy (375 mg/m2 as the initial dose and additional dose 100 mg, when the CD19 cell count was&gt; 5/ul or &gt;1%, done every month for 12 months) (regimen 3). Serum PLA2R autoantibodies were done before rituximab therapy and at six months of therapy initiation. Primary outcomes: Remission at the end of 12 months of therapy initiation. Secondary outcome: Complete remission (CR) and partial remission (PR), remission with different treatment schedules and adverse events. Definition: CR: reduction of proteinuria to &lt;0.5 g/d and with creatinine clearance of &gt;60 ml/min/1.73m2 and serum albumin &gt; 3.5 g/dl. PR: reduction of proteinuria to 0.5–3.5 g/day and stable serum creatinine. A p-value of &lt;0.05 was considered significant. Results The study included 87 patients of PMN. The mean age of the patients was 33.36±15.38 (range 15-61) years. Thirty-two (36.4%) and 56 (63.6%) patients received rituximab as the first-line therapy and for relapsing/resistant disease, respectively. Forty, 15 and 33 patients received regimen 1, 2 and 3, respectively. The median proteinuria, serum albumin and creatinine at the baseline before rituximab therapy was 5.90 (IQR 4.20,9.75) gm, 2.50 (IQR 2.15,3.25) g/dl and 0.88 (IQR 0.77,1.09) mg/dl, respectively. At the end of 12 months of follow-up, 55 (56.8%) patients received remission. Nineteen (21.6%) and 32 (36.3%) patients achieved CR and PR, respectively. In regimen 1, 12 (30%) and 13 (32.5%) patients achieved CR and PR, respectively. In regimen 2, 2 (13.3%) and 5 (33.3%) patients achieved CR and PR, respectively. In regimen 3, 5 (15.6%) and 14 (43.7%) patients achieved CR and PR, respectively. One patient in the CD19 targeted therapy (regimen 3) was lost to follow-up after the 1st dose; all but one patient in the received regimen three as a second-line treatment. There was a significant association of anti-PLA2R to clinical response (p&lt;0.05). There was no difference in the response rate among the three groups (p&gt;0.05). A total of 7 (7.9%) patients had severe adverse events, there was no difference in the 3 regimens. (p&gt;0.05) The cumulative dose in regimen 3 was significantly less as compared to regimen 1 & 2 (p&lt;0.01) Conclusion Rituximab induces remission in two-thirds of the patients with PMN. There is no significant difference in the remission rates between different rituximab regimens. CD19 targeted therapy is equally effective with lower cumulative dose.

The aim of this study is to evaluate the color changes and the stability at a 1-year follow-up of white spot lesions (WSLs) treated with an infiltrating technique by using etching and TEGDMA resin. The color of 22 white spot lesions and the sound adjacent enamel (SAE) were assessed with a spectrophotometer at T0 (baseline), T1 (after treatment), and T2 (1 year after). The color change ΔE (WSLs-SAE) at T0 vs. T1 were compared to evaluate the camouflage effect efficiency, and at T1 vs. T2 to assess the stability of outcomes. To evaluate the effect on the treatment outcome of gender, the presence or not of previous orthodontic treatment, WSLs onset more/less than 10 years, the age of the patient, and the ΔE WSL (T0 vs. T1) was analyzed. The difference between ΔE (WSLs-SAE) at T0 and T1 resulted in statistical significance (p < 0.01). No statistical difference was found between ΔE (WSLs-SAE) at T1 vs. T2. The variables considered showed no statistical differences in treatment outcomes. The results of our investigation show that the technique used is immediately effective and the camouflage effect keeps up and steady one year after treatment. Such results do not appear to be influenced by analyzed clinical variables.
