Exploratory analysis of the relationships among different methods of assessing adherence and glycemic control in youth with type 1 diabetes mellitus

Objectives: The present study examined four methods of assessing diabetes adherence (self-report, diary measure, electronic monitoring, and provider rating) within a population of youth with Type I Diabetes Mellitus (T1DM). Methods: Comparisons were conducted among the four methods of assessing diabetes adherence. Associations among the seven different measures of blood glucose monitoring (BGM) and HbA1c were examined. An exploratory stepwise regression analysis was conducted to determine the best predictors of glycemic control (i.e., Hemoglobin A1c; HbA1c) while controlling for relevant demographic variables. Results: The adherence measures appeared to be interrelated. The relationships between many of the BGM measures and HbA1c demonstrated a medium effect size. The Self Care Inventory (SCI) adjusted global score was the strongest predictor of HbA1c, even after taking the demographic variables into account. Conclusions: The SCI is a robust, easy-to-use, and cost-efficient measure of adherence that has a strong relationship to HbA1c. Demographic variables are important to examine within the context of different methods of assessing adherence. The research methodology utilized to assess both general diabetes adherence and more specific behavioral measurements of BGM should be clearly documented in future studies to ensure accurate interpretation of results.

Effectiveness of Groups for Adolescents With Type 1 Diabetes Mellitus and Their Parents

Peer- and family-based group therapies have been used as separate interventions to improve adjustment and self-management among youth with Type 1 diabetes mellitus. This study replicates a treatment protocol that combined these two types of diabetes management groups, while also using a wait-list control design methodology within an outpatient mental health clinic setting. General psychosocial and diabetes-related variables were assessed at baseline, immediately posttreatment, and 4 months posttreatment. Youths’ medical information, including metabolic control values, was extracted from medical charts for the 6 months prior to baseline and 6 months after treatment ended. At 4 months posttreatment, parents and youth reported increased parent responsibility, and parents reported improved youth diabetes-specific quality of life. Although there were no statistically significant changes in hemoglobin A1c values and health care utilization frequency from 6 months prior to and 6 months posttreatment, other psychosocial changes (i.e., increases in parent responsibility and diabetes-specific quality of life) were documented. Therefore, this treatment was found to be a promising intervention for use in an outpatient clinical setting to aid in improving the psychosocial functioning of youth with Type 1 diabetes mellitus

Use of an Observational Coding System with Families of Adolescents: Psychometric Properties among Pediatric and Healthy Populations

Objective: To examine reliability and validity data for the Family Interaction Macro-coding System (FIMS) with adolescents with spina bifida (SB), adolescents with type 1 diabetes mellitus (T1DM), and healthy adolescents and their families.Methods: Sixty-eight families of children with SB, 58 families of adolescents with T1DM, and 68 families in a healthy comparison group completed family interaction tasks and self-report questionnaires. Trained coders rated family interactions using the FIMS.Results: Acceptable interrater and scale reliabilities were obtained for FIMS items and subscales. Observed FIMS parental acceptance, parental behavioral control, parental psychological control, family cohesion, and family conflict scores demonstrated convergent validity with conceptually similar self-report measures.Conclusions: Preliminary evidence supports the use of the FIMS with families of youths with SB and T1DM and healthy youths. Future research on overall family functioning may be enhanced by use of the FIMS

Removal of Phenols from Wastewater with Encapsulated Horseradish Peroxidase in Calcium Alginate

Abstract -Horseradish peroxidase was encapsulated in calcium alginate for the purpose of phenol removal. Upon immobilization, pH profile of enzyme activity changes as it shows higher value at basic and acidic solution. Investigation into time course of phenol removal for both encapsulated and free enzyme showed that encapsulated enzyme had nearly similar efficiency in comparison with the same concentration of free enzyme; however the capsules were reusable up to four cycles without any changes in their retention activity

Half-dose photodynamic therapy for chronic central serous chorioretinopathy

Purpose: To report the outcomes of half-dose photodynamic therapy (PDT) in patients with chronic central serous chorioretinopathy (CSC). Methods: A chart review of patients with chronic CSC who had received half-dose verteporfin PDT (3 mg/m2) was performed. The main outcome measures were resolution of subretinal fluid and best corrected visual acuity (BCVA). Results: Fifty-three eyes of 51 patients with mean age of 45.01 ± 8.9 years were studied. Three, 6 and 12 months after half-dose PDT, subretinal fluid was completely resolved in 51 eyes (96.2). In 2 eyes (one patient), subretinal fluid decreased at 3 months but one year later, an increase in subretinal fluid was detected on optical coherence tomography (OCT) which completely resolved following additional PDT. Another patient with recurrence of subretinal fluid rejected further treatment. Mean baseline central subfield thickness was 385 ± 113.0 μm which was decreased to 235 ± 39.7, 247 ± 49.7, and 244 ± 49.52 μm after 3, 6 and 12 months, respectively (all P-values < 0.001). Mean BCVA was 0.33 ± 0.27 LogMAR before PDT and 0.11 ± 0.18, 0.11 ± 0.17, 0.17 ± 0.26 and 0.10 ± 0.23 LogMAR, 3, 6 and 12 months and at final visit (up to 60 months) after PDT, respectively (all P-values < 0.001). Improvement �2 lines in BCVA occurred in 20 eyes (37.7). Statistically significant correlations were found between improvement in BCVA and baseline BCVA, baseline central subfield thickness and central subfield thickness after resorption of subretinal fluid (P < 0.001, P= 0.04 and P= 0.01, respectively). No complications attributed to PDT were observed. Conclusion: Half-dose PDT is effective for treatment of patients with chronic CSC. © 2016 Journal of Ophthalmic and Vision Research

Scleral buckling surgery for rhegmatogenous retinal detachment with subretinal proliferation

PurposeTo evaluate the outcome of scleral buckling surgery in patients with rhegmatogenous retinal detachment (RRD) with subretinal proliferation.MethodsIn this retrospective study, a chart review of all patients with RRD associated with subretinal proliferation who were primarily treated with scleral buckling procedure, from April 2007 to April 2014, was undertaken. Main outcome measures were anatomical retinal reattachment and visual acuity.ResultsForty-four eyes of 43 patients including 24 males and 19 females with a mean age of 26.5±13.1 years were evaluated. Immediately after the surgery, retina was reattached in all eyes. However, five eyes (11.3) needed additional surgery for retinal redetachment. Single surgery anatomical success rate was 88.7. Four eyes (9.1), needed pars plana vitrectomy for the treatment of redetachment associated with proliferative vitreoretinopathy and scleral buckle revision surgery was successfully performed in the other eye. Best corrected visual acuity improved from 1.5±0.9 logMAR before surgery to 1.1±0.7 logMAR after surgery (P2 lines was found in 23 eyes (52.2) and worsening of best corrected visual acuity of >2 lines was observed in 2 eyes (4.5).ConclusionsScleral buckling surgery is highly successful in eyes with RRD associated with subretinal proliferation. © 2015 Macmillan Publishers Limited All rights reserved

Transcatheter closure of coronary artery fistulae: A literature review

Coronary artery fistulae (CAFs) are anomalous connections that bypass the myocardial capillary bed between 1 or more coronary arteries and other cardiac chambers or other vessels. These fistulae are usually asymptomatic and are, thus, diagnosed incidentally. However, larger CAFs can cause various symptoms such as angina, exertional dyspnea, syncope, palpitation, and even sudden cardiac death. Treatment options include surgical closure and percutaneous transcatheter closure (TCC) with comparable safety and efficacy. The choice of device in TCC depends on the anatomic characteristics of the CAF, the age and size of the patient, the size of the occluded vessel, the appropriate size of the catheter to be used, and the tortuosity of the catheter course to reach the intended point. Herein, we present 4 cases treated via TCC and then offer an in-depth discussion regarding this coronary artery anomaly. © 2020, Tech Science Press. All rights reserved

Temporal Artery Biopsy for Diagnosing Giant Cell Arteritis: A Ten-year Review

Purpose: To assess the use of temporal artery biopsy (TAB) in diagnosing giant cell arteritis (GCA) and to evaluate patients� clinical and laboratory characteristics. Methods: We conducted a retrospective chart review of patients with suspected GCA who underwent TAB and had complete workup in a tertiary center in Iran between 2008 and 2017. The 2016 American College of Rheumatology (ACR) revised criteria for early diagnosis of GCA were used for each patient for inclusion in this study. Results: The mean age of the 114 patients in this study was 65.54 ± 10.17 years. The mean overall score according to the 2016 ACR revised criteria was 4.17 ± 1.39, with 5.82 ± 1.28 for positive biopsies and 3.88 ± 1.19 for negative biopsies (p <0.001). Seventeen patients (14.9) had a positive biopsy. Although the mean post-fixation specimen length in the biopsy-positive group (18.35 ± 6.9 mm) was longer than that in the biopsy-negative group (15.62 ± 8.4 mm), the difference was not statistically significant (P = 0.21). There was no statistically significant difference between the groups in terms of sex, serum hemoglobin, platelet count, and erythrocyte sedimentation rate. There were statistically significant differences between the biopsy-negative and biopsy-positive groups with respect to patients� age and C-reactive protein level (P < 001 and P = 0.012, respectively). Conclusion: The majority of TABs were negative. Reducing the number of redundant biopsies is necessary to decrease workload and use of medical services. We suggest that the diagnosis of GCA should be dependent on clinical suspicion. © 2020 JOURNAL OF OPHTHALMIC AND VISION RESEARC

How reliable is the lacrimal scintigraphy report? An inter-observer agreement and reliability study

AIM: To assess the inter-observer agreement and reliability as well as intra-observer repeatability for lacrimal scintigraphy (LS) reports with and without considering the irrigation test results. � METHODS: A prospective, observational, cross sectional study. Two masked clinicians (lacrimal surgeon and nuclear medicine specialist) independently reported 100 LS images (50 patients of >6 years of age with unilateral anophthalmic socket) in a university hospital. The lacrimal surgeon performed a diagnostic irrigation test and repeated the report of the same LS images 2y after the first report (intra-observer agreement). A weighted Kappa analysis was performed to determine inter-observer agreement and reliability as well as intra-observer repeatability for the type (normal, partial and complete obstruction) and location (presac, preduct, and intraduct) of the obstruction. Subgroup analysis was also performed with consideration of irrigation test results. � RESULTS: A significantly moderate agreement was found between lacrimal surgeon and nuclear medicine specialist for both the type (Kappa=0.55) and location (Kappa=0.48) of obstruction. Agreement values were higher for the type (Kappa=0.61 vs 0.41) and location (Kappa=0.56 vs 0.31) of obstruction in cases with normal than abnormal irrigation test. Strong and significant intra-observer (lacrimal surgeon) repeatability was found for both the type (Kappa=0.66) and location (Kappa=0.69) of obstruction. LS showed no to slight reliability based on irrigation test. � CONCLUSION: A moderate agreement is found between lacrimal surgeon and nuclear medicine specialist regarding the interpretation of LS suggesting the importance of consensus groups among nuclear medicine specialists and lacrimal surgeons to create a common language for interpretation of LS. Intra-observer repeatability is strong for the lacrimal surgeon. © 2019, International Journal of Ophthalmology (c/o Editorial Office). All rights reserved
