Structures of multivariables affecting literacy: Cluster analysis.

Early literacy skills, the foundational abilities necessary for the development of literacy, must be examined holistically in preschool children. This study aimed to investigate early literacy skills in preschool children and determine how variables related to literacy development can be clustered by using a dendrogram. The study was conducted on 166 preschool children (75 female, 91 male; mean age: 65.9±4.4 months). Hierarchical cluster analysis (CA) was used to find the variable clustering trends. The 44 variables related to literacy (sociodemographic factors related to the child and family, child-parent relationship, child's behavior, and social, sensory integration, motor, and auditory linguistic skills) that were closest to each other in the dendrogram were clustered, and the situation was summarized by reducing them to two main clusters and six sub-clusters. This study elaborates on the implications of reducing multivariate complexity using CA. It is recommended that the relationships among the variables in this dendrogram structure are considered when new hypotheses and studies related to early literacy are designed.

Assessment of swallowing performance in patients with neurodegenerative disease: A hierarchical cluster analysis.

BACKGROUND: Swallowing is a complex process that alters with age and neurological diseases; swallowing disorders can be a consequence of both of them. As an advanced multivariate statistical method, hierarchical cluster analysis (HCA) was utilized to make the dendrograms, which was used to find the relationship between the variables. The purpose of this study is to ascertain the type of clustering exhibited by the variables using HCA and to evaluate the approach to major neurodegenerative diseases (MND) with swallowing disorders based on the results obtained. METHODS: Data were collected from a total of 173 patients from various neurological diagnoses, such as dementia, Parkinson's disease, stroke and polyneuropathy, aging between 42 and 104 (mean of age 72.85) by using the Montreal Cognitive Assessment, the Edinburgh Feeding Evaluation Scale (EdFED), the Eating Assessment Tool (EAT-10), and the Modified Mann Swallowing Ability test. From the collected data, dendrograms were formed by using HCA with Ward linkage method. RESULTS: Based on cluster analysis results, clusters demonstrate statistical significance. They center around EdFED, EAT-10, and age in each MND. In healthy individuals, variables are not clustered as in the patient group. This study holds importance as it can give clinicians a different perspective on determining and managing the elderly population's swallowing problems. CONCLUSIONS: The HCA method explicitly proposes which variables should be examined concurrently in the clinic for MND. This research is one of the pioneering studies conducted by using the HCA method.

The effect of virtual reality-based interventions on pain in burn wound care in burn patients: A systematic review and meta-analysis.

OBJECTIVE: The aim of this systematic review and meta-analysis was to evaluate the effect of virtual reality on pain in adult burn patients. METHOD: A comprehensive systematic search was conducted on international electronic databases such as PUBMED, Web of Science, Science Direct, CINAHL, Scopus, TÜBITAK-ULAKBIM, Dergipark and TR Dizin with keywords. This systematic review and meta-anaysis was developed using the PRISMA checklist. The risk of bias was assessed independently for each included study by using the Cochrane risk of bias tools. RESULTS: Based on the results of systematic review it was decided to include 15 studies in meta analyses. Based on fifteen pooled studies, the estimated SMD was minus 0.62 with a 95 % CI of minus1.15 and minus 0.09 according to the results of the random effects model as recommended by heterogeneity tests. Of pooled 15 studies, 11 studies found less pain score among VR patients, while the remaining four reported higher pain score among VR patients. CONCLUSIONS: The results show that virtual reality can be used effectively in pain management during burn care in adult patients. Since the number of studies in adult burn patients is very limited, it is recommended to conduct large-sample studies with high level of evidence including nursing interventions on this issue.

Using Cluster Analysis to Identify Metabolic Syndrome Components and Physical Fitness in Patients with Metabolic Syndrome.

Background: Metabolic syndrome (MetS) comprises a cluster of cardiovascular risk factors. Physical inactivity and reduced physical fitness are associated with one or more components of MetS. However, MetS has many components, and the unclear relationship between the components and physical fitness parameters can provide a plain and straightforward understanding of the clustering method. Aim: To identify the relationship between physical fitness parameters, physical activity levels, and components of MetS using hierarchical cluster analysis. Methods: One hundred twenty-one patients (mean age = 51.4 ± 7.1/years, F:90, M:31) who were diagnosed as having MetS according to the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III) criteria were included in the study. Fasting plasma glucose (FPG), high-density lipoprotein cholesterol (HDL-C), and triglyceride (TG) were analyzed. Systolic and diastolic blood pressures, (SBP and DBP), were evaluated. Body composition (waist and hip circumference, (WC and HC), waist-to-hip ratio (WHR), body mass index (BMI), percent body fat, and visceral fat), upper and lower extremity muscle strength (dynamometer), and functional exercise capacity [6-minute walk test (6MWT)] were assessed as physical fitness parameters. Physical activity levels were assessed using a pedometer and number of steps (NS) was determined. Results: Of the patients, 45.5% were diagnosed as having MetS based on four components. The dendrogram consisted of two main clusters and four subclusters. The main cluster I composed of BMI, HC, WC, visceral fat, HDL-C, percent fat, SBP, DBP, and percent quadriceps. The main cluster II comprised FPG, TG, WHR, handgrip strength, 6MWT, and NS. Conclusion: MetS components clustered with different physical fitness parameters. The clusters in the dendrogram can provide substantial implications for heterogeneous MetS components and physical fitness parameters. Future studies are needed to elucidate the effectiveness of dendrogram-derived exercise programs in MetS.

Evaluation of cycloplegic and noncycloplegic performance of spot vision screener in detection of amblyopia risk factors using 2021 AAPOS guidelines.

PURPOSE: This research evaluates the effectiveness of the Spot Vision Screener (SVS) before and after cycloplegia to detect amblyogenic refractive errors in children. METHODS: Children ages 3 to 10 years old were screened by the SVS before and after cycloplegia. Sensitivity, specificity, positive and negative predictive value, paired t-test, Bland-Altman plot and receiver operating characteristic area under the curve were evaluated by comparing the results of the SVS (v3.0.05) measurements with the results of the cycloplegic Topcon autorefractometer according to the 2021 guidelines of the American Association for Pediatric Ophthalmology and Strabismus. RESULTS: Both eyes of 211 patients aged 3 to 10 years old were included. Regarding the amblyopia risk factors, the noncycloplegic SVS had 65.7 % sensitivity, 94.9 % specificity, 81.2 % positive predictive value and 89.3 % negative predictive value. The SVS's sensitivity increased from 65.7 % to 81.9 % with cycloplegia compared to noncycloplegic SVS results. The sensitivity detection of hyperopia was improved from 4.2 % to 100 % after cycloplegia. Areas under the receiver operator characteristic curve for noncycloplegic SVS and cycloplegic SVS were 0.506 (95 % CI, 0.395 to 0.646, p = 0737) and 0.905 (95 % CI, 0.915 to 0.971, p < 0.001) for hyperopia, respectively. Using the +1.64 D revised cutoff criteria for hyperopia increased sensitivity from 4.2 % to 78 %. CONCLUSION: Noncycloplegic SVS measurements showed relatively high specificity in detecting amblyopia risk factors. The fact that noncycloplegic measurements have a very low sensitivity for hyperopia is an important weakness of the SVS, especially because hyperopia is the most frequently encountered refractive error in very young children. It should be noted that amblyogenic hyperopia may be overlooked by an SVS without cycloplegia.

Structural and psychological empowerment and burnout among nurses: A systematic review and meta-analysis.

AIM: This study aims to review available evidence about the relationship between structural and psychological empowerment and burnout among nurses. BACKGROUND: Nurses are key healthcare providers, who experience higher levels of burnout due to uncertainty and role conflicts about nursing roles and responsibilities and poor management. Nurse empowerment is an effective approach to reduce nurse burnout and enhance patient care quality. INTRODUCTION: Positive working conditions along with positive attitudes and perceptions for nurses are crucial in the workplace. Nurse empowerment in the workplace results in quality improvements in work life and the provision of healthcare. METHOD: We conducted a systematic review in accordance with the recommendations of the Joanna Briggs Institute and the PRISMA guideline. Relevant studies published between 2007 and 2022 were identified via PubMed, CINAHL, Web of Science, Scopus, Cochrane Library, Ovid MEDLINE (R), Science Direct and Turkish scientific literature databases. Studies that reported correlation coefficients were pooled to conduct a meta-analysis. RESULTS: Random-effects meta-analyses showed a negative association between structural and psychological empowerment and emotional exhaustion. The overall findings showed a moderate and negative association between the six dimensions of structural empowerment and depersonalization. There was a positive association between structural empowerment and personal accomplishment. DISCUSSION: There is a relationship between decreased burnout levels and nurse empowerment. The causal relationship between empowerment and burnout levels needs to be investigated in various healthcare settings in several countries. CONCLUSION: The relationship between structural and psychological empowerment and burnout levels emphasizes that empowerment can reduce nurse burnout. Nurse empowerment is a critical management strategy for improving the quality of life for nurses, increasing the quality and effectiveness of patient care and achieving positive outcomes. IMPLICATIONS FOR NURSING AND HEALTH POLICY: The encouragement and empowerment of nurses for prompt decision-making and effective resource utilization, reduces nurse burnout, enhancing nurses' job commitment, productivity, satisfaction and competence along with increased quality of care. The encouragement of nurses as empowered managers at the macro, meso and institutional levels not only improves the overall quality of health services but also helps to find solutions for the issues concerning healthcare service users and the health system environment.

Adaptation and psychometric testing of the Turkish evaluation of daily activity questionnaire in people with rheumatoid arthritis.

PURPOSE: The aims were to translate the Evaluation of Daily Activity Questionnaire (EDAQ) into Turkish, then test validity and reliability in people with rheumatoid arthritis (RA) in Turkey. MATERIAL AND METHODS: Phase 1: The EDAQ was forward and backward translated, culturally adapted following cognitive debriefing interviews with participants with RA (n = 10) and finalized by an expert committee. Phase 2: Participants (n = 215) completed a questionnaire including the EDAQ, Health Assessment Questionnaire (HAQ), and Short-Form 36 v1 (SF-36v1). Two weeks later, the EDAQ was again completed for test-retest reliability (n = 82:38%). Internal construct validity was assessed using Rasch analysis. Internal consistency, concurrent validity, and test-retest reliability were assessed. RESULTS: Following cultural adaptation, one item was removed, and examples increased or changed. Cronbach's α values were 0.71 - 0.93 for all EDAQ domains, that is, acceptable to good. The EDAQ met Rasch model requirements for fit (excellent construct validity: p > 0.05). Concurrent validity was moderate to strong for most EDAQ domains with HAQ (rs 0.49-0.81) and SF-36-v1 Physical Function (rs 0.42-0.70). There was excellent test-retest reliability for all domains (ICC (2,1): 0.95-1.00). CONCLUSION: The Turkish EDAQ is a valid, reliable measure of daily activity ability for use in practice and research with Turkish speakers with RA.

The Evaluation of Daily Activity Questionnaire provides a comprehensive evaluation of daily activity ability for people with rheumatic and musculoskeletal diseases.The Turkish Evaluation of Daily Activity Questionnaire is a valid, reliable patient-reported outcome measure in patients with rheumatoid arthritis, who considered it easy to complete.The Turkish Evaluation of Daily Activity Questionnaire is suitable for use in clinical practice and research to evaluate daily activity ability in people with rheumatoid arthritis.

Investigation of adolescents and their mothers in terms of nomophobia.

BACKGROUND: Nomophobia (NoMP) is the fear of being unable to interact with others via mobile phones and is a current topic in adolescents` mental health. The purpose of this study was to investigate the association between NoMP in adolescents and their mothers` level of NoMP. METHODS: The levels of depression, anxiety, attention deficit/hyperactivity-impulsivity symptoms, NoMP, and perceived parental emotional availability were examined. RESULTS: One hundred fifty-five adolescents (60% girls) were included in the study with their mothers. Ninetythree (60%) adolescents (67.7% girls) and 64 (41.3%) mothers were classified as nomophobic. There was a positive correlation between the NoMP levels of adolescents and their mothers. Nomophobic girls perceived less paternal support. All psychopathologic symptoms were higher in the nomophobic mothers. There was no difference between nomophobic and non-nomophobic adolescents in terms of maternal psychopathologies. CONCLUSIONS: We suggest that parental effects should be investigated during the assessment of NoMP, especially in adolescent girls. The phone usage habits of mothers and their relationship with their adolescent children were closely associated with adolescent NoMP.

Is Dry Needling Treatment an Extra Contribution to Conventional Treatment for Hemiplegic Shoulder Pain? A Prospective, Randomized Controlled Study.

Objective: This research was conducted to evaluate the effect of adding dry needling (DN) treatment to conventional rehabilitation for pain, range of motion (ROM), and functionality in patients with hemiplegic shoulder pain (HSP). Materials and Methods: Patients with HSP (n = 38) were divided into 2 groups. A multimodal rehabilitation protocol, including physical therapy and exercise treatments, was given to both groups (5 sessions per week for 15 sessions). In addition to this rehabilitation, 3 sessions of DN therapy were given to one of the 2 groups. Measurements were a visual analogue scale; ROM; and 2 other scales (Quick Disability of the Arm, Shoulder, Hand; and the Fugl-Meyer Assessment Upper Extremity). Evaluations were made before, after, and at the third month after treatment. Results: While a statistically significant improvement was seen in both groups in all parameters after their treatments, a statistical superiority was found in the conventional treatment+DN group (P < 0.05). However, the differences were not greater than the minimal clinically important difference values (MCID). At the 3rd month follow-up, there was no difference in pain and functionality parameters between the groups, while flexion and abduction measurements were higher in the conventional treatment+DN group (P < 0.05). Conclusions: Adding DN treatment to conventional rehabilitation did not show any difference except in some joint ROM measurements in the subacute time. Although the changes found were statistically significant, they were not clinically significant as they did not reach MCID values.This study was registered prospectively at ClinicalTrials.gov (ref. no: NCT04790071).

[Evaluation of pre- and post-transplant electroencephalographic examination in hematopoietic stem cell transplant patients]. / A transzplantáció elotti és utáni elektroencefalográfiás vizsgálatok értékelése haematopoeticus ossejttranszplantált betegeknél.

Background and purpose:

Haemato­poietic stem cell transplantation (HSCT) is one of the most effective treatment methods for many malignant and non-malignant diseases. In this study, we aimed to detect electroencephalographic (EEG) anomalies at an early stage in patients who underwent allogeneic and autologous HSCT and required the management of potentially life-threatening non-convulsive seizures.

The study was conducted with 53 patients. The age, gender, HSCT type (allogeneic or autologous), and treatment regimens applied before and after HSCT were recorded. All patients underwent EEG monitoring twice, once on the first day of hospitalization and again one week after conditioning regimens began and HSCT was performed.

When the pre-transplant EEG findings were examined, 34 (64.2%) patients had normal EEGs and 19 (35.8%) had abnormal EEGs. After transplantation, 27 (50.9%) had normal EEG findings, 16 (30.2%) had a basic activity disorder, 6 (11.3%) had a focal anomaly, and 4 (7.5%) had a ge­ne­ra­lised anomaly. In the allogeneic group, the anomaly rate in post-transplant EEGs was significantly higher than that in the auto­lo­gous group (p<0.05).

It is important to consider the likelihood of epileptic seizures in the clinical follow-up of HSCT patients. EEG monitoring is crucial for the early diagnosis and treat­ment of such non-convulsive clinical ma­ni­festations. 

New parameters on prediction of severity of transient tachypnea of the newborn.

BACKGROUND: Transient tachypnea of the newborn (TTN) is a common clinical problem that often occurs in the first hours of life. Although it is considered to be a benign clinical course, some cases may have severe symptoms and require ventilation support. In this study, we aimed to determine the association between the mean platelet volume (MPV), nucleated red blood cells (NRBCs), right ventricular systolic pressure (RVSP), and the severity of TTN. METHODS: Patients with TTN were divided into two groups according to Silverman score (<7: group 1 [n: 34] and ≥7: Group 2 [n: 30]). The groups were compared in terms of demographic characteristics, hematologic parameters, and RVSP within the first 24 hours after admission. RESULTS: Mean birth weight of the patients was 3033.4 ± 364.1 g and median gestational age was 38 weeks (min-max: 34-42). Patients in Group 2 were found to require higher nasal continuous positive airway pressure (nCPAP) support and longer duration of oxygen treatment (p: 0.001). Patients in Group 2 had significantly higher thrombocyte, absolute NRBCs count, NRBCs/100 WBCs, and RVSP levels (p < 0.05). Hemoglobin and hematocrit levels were found significantly higher in group 1(p < 0.05). In logistic regression analysis, NRBCs/100 WBCs was found to be the most important independent parameter that affects Silverman score at admission (OR: 7.065, CI: 1.258-39.670, p: 0.026). DISCUSSION: This is the first study that investigates the association between NRBCs, RVSP, and severity of TTN. We think that elevated NRBCs and RVSP values are helpful for clinicians in decision making for referral of the patients to a secondary or a tertiary level of NICU and also inform the families about prognosis.

A Single-Center Experience: What is the Effect of Sleeve Gastrectomy in Patients With a BMI ≥ 50 kg/m²?

BACKGROUND: Our research aimed to see how sleeve gastrectomy (SG) affects weight loss and comorbidities in patients with a body mass index (BMI) ≥ 50 kg/m². MATERIALS AND METHODS: Prospectively kept data of patients with a BMI ≥50 kg/m² who underwent SG between February 2016 and February 2020 were evaluated. RESULTS: A total of 138 patients with a BMI ≥ 50 kg/m² were operated on. The average BMI was 56.36±7.661, the average age was 37.41±12.33. Forty-eight patients underwent concomitant cholecystectomy and/or hiatal hernia repair (HHR). The percentage of excess weight loss (EWL%) of patients at the 3rd, 6th, 12th, 18th, and 24th months were 36%, 54%, 67%, 72%, and 74%, respectively. Mean BMI values of the 0th, 3rd, 6th, 12th, 18th, and 24th months were 56, 45, 39, 35, 33, and 33, respectively. 0th, 3rd, 6th, 12th, 18th, and 24th months were significantly different for EWL%, total weight loss (TWL%), and BMI variables (p<0.001), but EWL% (p=0.527), TWL% (p=0.396) and BMI (p=0,657) were not found significantly different between the 18th and 24th months. When EWL% ≥ 50 was accepted, the success rate was 93% (n=93) and 92% (n=50) at the 18th and 24th months, respectively. While there was 82% remission in type 2 diabetes mellitus (DM) and 90% in hypertension (HT), the remission rate in patients with obstructive sleep apnea syndrome (OSAS) and gastroesophageal reflux disease (GERD) undergoing HHR was 100%. CONCLUSIONS: In patients with a BMI ≥ 50 kg/m², SG seems to be an effective and safe therapy option as the first line for weight loss and treatment of comorbid diseases. Further long-term studies are needed to confirm these results.

Comparison of Local and Systemic Ibuprofen for Relief of Postoperative Pain in Symptomatic Teeth with Apical Periodontitis.

BACKGROUND One of the aims of endodontic treatment is to control preoperative and postoperative pain. The present study evaluated the effects of local and systemic ibuprofen on postoperative pain. It aimed to determine the most effective method for relieving postoperative pain due to chemomechanical preparation. MATERIAL AND METHODS Ninety patients with symptomatic apical periodontitis were randomly assigned to local ibuprofen, systemic ibuprofen, and control groups (n=30 each). Chemomechanical preparations were performed using a ProTaper Universal Ni-Ti rotary file under 2.5% sodium hypochlorite and 17% ethylenediaminetetraacetic acid irrigation. After the root canals were dried with sterile paper points, while Odontocide paste was applied into the root canals of the patients in the local ibuprofen group, calcium hydroxide paste was applied into the root canals of the patients in the systemic ibuprofen and control groups. Following completion of the endodontic treatment procedure, 200 mg ibuprofen was prescribed to patients in the systemic ibuprofen group. Friedman and Wilcoxon tests were used for statistical analysis. RESULTS Posttreatment pain scores were recorded at 6, 12, 24, and 48 h using a visual analogue scale. Although there were no significant differences between the local ibuprofen group (Odontocide) and the control group (Ultracal) (P>0.05), pain scores in the systemic group (Ultracal+200 mg ibuprofen) were significantly lower than those in the other 2 groups (P<0.05). CONCLUSIONS These results indicate that systemic administration of ibuprofen is effective for postoperative pain relief.

Dendrogram for Anthropometric and Biomechanical Variables Causing Foot Deformities by Using Hierarchical Cluster Analysis: A Cross-Sectional Study.

Objective: The purpose of this study was to determine the factors associated with pathomechanical conditions and to determine the clustering tendency of the variables by dendrogram. Methods: The cross-sectional study was carried out with 108 physiotherapy students aged 21.36 ± 1.35 years. The variables included in the study were quadriceps (Q), subtalar, and valgus angles and medial longitudinal arch (MLA) and hallux valgus angles. The MLA and metatarsal width were measured and navicular drop tests performed under weighted and nonweighted conditions. Hierarchical cluster analysis was used to determine the clustering tendency of the variables and see how these clusters might converge. Results: Two main clusters of variables were obtained using hierarchical cluster analysis. In the first main cluster, the weighted and nonweighted metatarsal widths of the left and right sides, age, hallux valgus angle, and subtalar pronation angles of the left and right sides were found to be significantly related to each other. In the second main cluster, the weighted and nonweighted MLA, knee valgus and Q angles, weight, body mass index, weighted and nonweighted navicular drop values, gender, and height were found to be significantly related to each other. Conclusion: The relationships between variables such as MLA, hallux valgus angles, knee valgus and Q angles, weight, body mass index, weighted and nonweighted navicular drop values, gender, and height seem to be associated with pathomechanical conditions.

Experience and views of nurses on nursing services and personal protective equipment in Covid-19 pandemic the case of Turkey: A cross-sectional study.

BACKGROUND: During the COVID-19 pandemic, there were difficulties in planning the nursing workforce and personal protective equipment. AIM: The purpose of this study was to identify the experiences and views of nurses on personal protective equipment use and nursing workforce planning in Turkey. METHODS: This descriptive and cross-sectional study was conducted between 23 December 2020 and 3 May 2021, among 362 nurses who agreed to participate in this study voluntarily. RESULTS: The findings showed that the satisfaction scores were significantly higher for those nurses who worked in 8-h shifts, were not assigned to different clinics, were notified by an official letter and 1 week or month in advance before assignment compared with nurses in other categories. CONCLUSIONS: The problems that have arisen in the COVID-19 pandemic process have made it clear that there is a need for a nursing services management model in the event of an epidemic. IMPLICATIONS FOR NURSING MANAGEMENT: This study reveals the need for the 'Nursing Services Management Model in the Event of an Epidemic' by discussing the problems of nurse workforce planning and protective personal equipment management from the perspective of nurses who experienced these problems at first hand.

New Distinct Component Patterns for Plantar Pressure Variables by Using Principal Component Analysis.

BACKGROUND: It is important to determine the plantar pressure distribution of schoolchildren by applying static and dynamic foot analyses using a pedobarography device. However, it is difficult to obtain clear interpretations from results that can be explained by a large number of plantar pressure variables. The aim of this study was to use principal component analysis (PCA) to predict the main components for reducing the size of big data sets, provide a practical overview, and minimize information loss on the subject of plantar pressure assessment in youths. METHODS: In total, 112 schoolchildren were included in the study (mean ± SD: age, 10.58 ± 1.27 years; body mass index, 18.86 ± 4.33). During the research, a pedobarography device was used to obtain plantar pressure data. Each foot was divided into six anatomical regions and evaluated. Global and regional plantar pressure distributions, load and surface areas, pressure-time integrals, weight ratios, and geometric foot properties were calculated. RESULTS: The PCA yielded ten principal components that together account for 81.88% of the variation in the data set and represent new and distinct patterns. Thus, 137 variables affecting the subject were reduced to ten components. CONCLUSIONS: The numerous variables that affect static and dynamic plantar pressure distributions can be reduced to ten components by PCA, making the research results more concise and understandable.

Comparison of the Effect of Spreader and T-Splay Graft in Internal Nasal Valve Management.

BACKGROUND: The midvalve area is one of the most important anatomical points in rhinoplasty procedures. An additional intervention may be required to ensure there is no narrowing in this region. For this reason, several different techniques are used. Spreader graft technique is the most common of all these methods. T-splay graft technique is an alternative method that can effectively widen the angle of the midvalve. The present study compares the anatomical and functional outcomes of these two methods. METHODS: The study included 60 cases who presented to our clinic for rhinoplasty. The cases were evaluated demographically, anatomically, and functionally, and the acquired data were recorded. All cases were preoperatively administered the Visual Analogue Scale, the Nasal Obstruction Symptom Evaluation scale, and the modified Glatzel mirror test. By randomly selecting the cases, midvalve restoration was performed with a spreader graft in 30 cases and a T-splay graft in 30 cases. RESULTS: A comparison of the Visual Analogue Scale, the Nasal Obstruction Symptom Evaluation scale, and the modified Glatzel mirror test scores revealed that the scores of both groups at postoperative months 3 and 6 were significantly different from the preoperative measurement values. CONCLUSIONS: Although spreader graft technique is a very effective method in midvalve management, we believe that T-splay graft technique may also produce effective outcomes. In addition, the midvalve functions could be better simulated anatomically and functionally with T-splay graft technique. Therefore, we believe that T-splay graft technique is an alternative method that can be safely used in selected cases.

Investigating the correlation between pulmonary function tests and ultrasonographic diaphragm measurements and the effects of respiratory exercises on these parameters in hemiplegic patients.

OBJECTIVE: To investigate the correlation of DUS and pulmonary function tests (PFTs), and investigate the effects of respiratory exercises on the above parameters. METHODS: For the treatment group (n=20), neurological rehabilitation and respiratory exercise program, and for the control group (n=21), only a neurological rehabilitation program was implemented for 30 sessions. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), end-inspiration diaphragm thickness (IDT), end-expiratory diaphragm thickness (EDT), and diaphragm thickening ratio (DTR) were measured pre- and post-treatment. RESULTS: IDTs and EDTs as well as DTRs of affected side (p < .001, .001, and .03, respectively) and intact side (p < .001, .001, and .02, respectively) were found to improve post-treatment than before treatment in the treatment group. Similarly, FVC, FEV1, and FEV1/FVC, were better post-treatment than before treatment in the treatment group. Moreover, the affected side IDT was positively correlated with FVC and FEV1 before treatment (r = .38, p = .03 and r = .35, p = .02) and post-treatment (r = .46, p = .02 and r = .39, p = .03). The affected side DTR was positively correlated with FVC and FEV1 before treatment (r = .44, p = .01 and r = .40, p = .02) and post-treatment (r = .32, p = .03 and r = .40, p = .04). CONCLUSION: DUS can be used for the evaluation of respiratory problems in stroke patients. Moreover, breathing exercises improve these parameters in stroke patients, and they can be followed up by DUS.

Investigation of the factors affecting the e-learning process in occupational therapy education during the pandemic with principal component analysis.

Introduction: The aim of this study is to examine the factors affecting the e-learning process in occupational therapy education in the COVID-19 period. Method: In the study, a form containing personal information and questions about the e-learning process, the International Physical Activity Questionnaire, the Academic Self-Efficacy Scale, the Perceived Stress Scale, and the Rosenberg Self-Esteem Scale were applied to 253 occupational therapy students via the Google form. Principal component analysis was used to evaluate the data. Results: A large number of questionnaires were applied in the study, and principal component analysis, an advanced statistical method that enables the interpretation of this type of big data more effectively, was used. 13 components were determined, and a variance of 88% was explained. The main components were listed as students' self-perception about the education system, learning methods, home and university environment, information technologies, physical activity level, and academic performance/participation. Conclusion: We hope that the results of our study will provide a perspective on what innovations can be made for quality improvement in occupational therapy education. It would be beneficial to increase student feedback by applying similar studies in other education programs.

New approach to the risk variables for administration of fibrinogen in patients with postpartum hemorrhage by using cluster analysis.

OBJECTIVE: To analyze all the variables in women who received fibrinogen for postpartum hemorrhage (PPH) using hierarchical cluster analysis, to provide greater insight into the risk variables involved in these women. METHODS: This retrospective study of women with at least 500 mL of bleeding at birth or during the postpartum period and treated with fibrinogen was conducted at the Department of Obstetrics and Gynecology, Atatürk University School of Medicine from January 2013 to January 2018. Data on the women were obtained from medical records and various risk variables were recorded and analyzed using hierarchical cluster analysis. RESULTS: A total of 114 women with PPH were included in the study. Based on a dendrogram, three main clusters of similar quality variables were created: 1) gravida, parity, age, cervical/vaginal hematoma, laparotomy, hypogastric artery ligation, uterine artery embolization, uterine artery ligation, uterine atony, distance from outer center, lowest hemoglobin, preoperative platelets, endometritis, preoperative white blood cells; 2) lowest fibrinogen, highest fibrinogen, type of birth, placenta invasion anomaly, Bakri balloon tamponade, postpartum hysterectomy, preoperative activated partial thromboplastin time (APTT), preoperative international normalized ratio (INR), placental abruption, in-utero ex fetus; 3) postoperative APTT, postoperative INR, maternal mortality, erythrocyte transfusion, plasma transfusion, hospital stay time, disseminated intravascular coagulation/HELLP syndrome, highest hemoglobin, blood group, postoperative platelets, platelet transfusion, pre-eclampsia/eclampsia, fibrinogen extract. CONCLUSION: According to the cluster analysis, we should keep fibrinogen extract in the foreground especially in the treatment of hemorrhage in patients with variable conditions. As a result, we can determine whether fibrinogen extract, which has a high economic cost, should be kept at each center. We can also direct which patient will be referred in accordance with the referral steps.
