RESUMEN

Background: Recent changes in nutrition trends may lead to health issues. In particular, the unhealthy eating habits of young adults suggest that future generations may be at risk. Therefore, the importance and necessity of nutrition literacy is becoming increasingly apparent. Purpose: The purpose of this study was to create a Turkish version of a short nutrition literacy (S-NutLit-Tr) scale for young adults developed by Vrinten et al (2023). Methods: This research involved 115 young adults from Istanbul Gelisim University, who were selected through convenience sampling, a non-probability sampling method. After the original S-NutLit scale was translated into Turkish, the validity and reliability of the determined factor structure were tested on 115 young adults. Internal consistency was examined with the Cronbach Alpha coefficient. Confirmatory factor analysis was employed to validate the two sub-scale structures. Finally, measurement invariance was tested concerning participants' gender, aiming to ascertain whether the scale captured equivalent characteristics across different groups. Results: As a result of the reliability analysis conducted with the scale of S-NutLit-Tr, the Cronbach Alpha coefficient was obtained as 0.86 for the scale of S-NutLit-Tr. Additionally, it was found to be 0.84 and 0.77 for the "information skills" and "expert skills" sub-scales, respectively. Accordingly, the scale of S-NutLit-Tr was found to be reliable. To examine the two sub-scale factor structures of the S-NutLit-Tr scale, fit indices were examined: χ2/df (1.246), GFI (0.923), IFI (0.975), TLI (0.967), CFI (0.974), RMSEA (0.046), and SRMR (0.055) and it was observed that the indices were within acceptable limits. In the analysis results obtained through the multi-group confirmatory factor analysis for measurement invariance, it was observed that the ∆CFI and ∆TLI values across all indices were less than or equal to 0.01. Consequently, it was observed that the item-factor structure, factor loadings, variances, covariances, and error variances of the scale were equivalent for both male and female young adults. Conclusion: The study found that the scale of S-NutLit-Tr for young adults was a valid and reliable measurement tool in Turkish culture.

RESUMEN

OBJECTIVE: To evaluate the clinical characteristics and treatment outcomes of patients with chronic pulmonary aspergillosis (CPA) and to determine risk factors for disease recurrence. METHODS: A total of 43 patients with CPA (mean ± SD age: 61.4 ± 10.5 years, 83.7% were males) were included in this retrospective study. Data on demographic, clinical and disease-related characteristics, galactomannan (GM) test positivity in bronchoalveolar lavage (BAL) samples, histopathological diagnosis, imaging (CT) findings and CPA forms, antifungal therapy, recurrence rate and time to recurrence were recorded. RESULTS: Chronic obstructive pulmonary disease (COPD;76.7%) was the leading predisposing factor, and the aspergillus nodule (37.2%) was the most prevalent CPA form.GM test positivity was noted in 89.7% (35/39) of BAL samples. Median duration of voriconazole treatment was 180 days. CPA recurrence was noted in 14.0% of patients, while the comorbid tuberculosis sequela (66.7% vs. 16.2%, p = 0.02) and mild immunosuppressive disorder (100.0% vs. 51.4%, p = 0.032) were significantly more common in patients with recurrence vs. those without recurrence. Recurrence rate was 50.0% (3 of 6 patients) in patients with simple aspergilloma, and ranged from 0.0% to 25.0% in those with other CPA forms. Treatment duration and time to recurrence ranged 70-270 days and 1.1-37 months, respectively in simple aspergilloma, while they were ranged 150-180 days and 30-43.3 months, respectively in other CPA forms. CONCLUSIONS: Our findings indicate the importance of considering CPA in differential diagnosis in patients with predisposing conditions, and emphasize the tuberculosis sequela, immunosuppressive disorder and the certain CPA forms managed with shorter duration of antifungal therapy (i.e., simple aspergilloma) as the potential risk factors of CPA recurrence.

RESUMEN

Purpose: The purpose of this study is to carry out the Turkish adaptation study of the personal responsibility scale developed by Ren et al for Chinese university students and to examine the validity and reliability of the adapted scale. The original scale was developed to determine the personal responsibility levels of Chinese university students. This research is very important in terms of determining the personal responsibility levels of Turkish university students. Methods: This research involved university students, who were selected through purposeful sampling, a non-probability sampling method. After the original scale was translated into Turkish, a pilot study was conducted on 165 students and exploratory factor analysis was conducted to reveal the scale structure. The validity and reliability of the determined factor structure was tested on 259 students. Internal consistency was obtained with the Cronbach Alpha coefficient. Confirmatory factor analysis was used to check the validity of the two subscale structure. Results: To examine the two-dimensional factor structure of the scale, fit indices were examined: X2/df (1.591), GFI (0.949), IFI (0.937), TLI (0.920), CFI (0.936), RMSEA (0.048) and SRMR (0.050) and It was observed that the indices were within acceptable limits. In the analysis results conducted with the multi-group confirmatory factor analysis method for measurement invariance, it was observed that ∆CFI and ∆TLI values among all metrics were less than or equal to 0.010. Conclusion: The Turkish version of the personal responsibility scale for Chinese college students, consisting of 12 items and two subscales, was proven to be a confirmatory and reliable tool to measure university students' awareness of personal responsibility.

RESUMEN

OBJECTIVE: To compare the results of different nutritional screening tools, including NRS-2002, PG-SGA, and NUTRISCORE for the detection of malnutrition in oncology outpatients. STUDY DESIGN: A descriptive study. Place and Duration of the Study: Daily Chemotherapy Unit, Umraniye Training and Research Hospital, Istanbul, Turkiye, between June and July 2021. METHODOLOGY: A total of 69 patients were included in the study, receiving cancer therapy in an outpatient setting. The NRS-2002, PG-SGA, and NUTRISCORE scores were calculated to determine the nutritional status. RESULTS: The mean age of the patients was 56.74 ± 13.48 years, and 59.4% were females. The mean BMI was 27.29 ± 5.27 kg/m2. Among the patients, 55.1% had insufficient nutritional intake or were at risk of malnutrition according to the NRS-2002, 40.6% according to NUTRISCORE, and 59.4% according to the PG-SGA. There was a significant agreement between the results of the NRS-2002 and PG-SGA in a McNemar test (Kappa: 0.320, p = 0.008). CONCLUSION: NRS-2002 and PG-SGA tools offered greater sensitivity in terms of capturing more patients in the precachectic state than NUTRISCORE. Among these, the NRS-2002 is a shorter test, and thus, would seem to be more practical than the PG-SGA. KEY WORDS: Oncology, Malnutrition, Screening tools, NRS-2002, PG-SGA, NUTRISCORE.

RESUMEN

BACKGROUND: Young adulthood is a critical developmental period in which individuals establish life-long health behaviors and take responsibility for their own health care. Health promotion strategies tailored to young adults, leveraging digital tools, and addressing challenges exacerbated by events like the COVID-19 pandemic are needed. The aim of this study was to adapt the post-pandemic health promotion behavior of young adults in the digital age (PS-SGD) scale to the Turkish population in order to assess and compare the health behavior of young adults after the pandemic. METHODS: A total of 312 participants, aged between 19 and 29 years, were included in the study via non-probabilistic criterion sampling, while the Turkish adaptation process started with translation and back translation methods performed with three language and two health science experts. For statistical analysis, EFA and CFA were conducted to evaluate internal consistency and structural validity. Confirmatory factor analysis was utilized to confirm the structure of the six sub-dimensions. Additionally, measurement invariance was examined regarding participants' gender to determine if the scale accurately captured similar traits across diverse groups. The relationship between the test-retest data was tested by Pearson correlation to measure consistency and its invariance over time. RESULTS: The gender distribution of the sample was found to be 61.3% female and 38.7% male. According to the results of EFA, items 8 and 18 were removed from the Turkish-adapted version. As a result of the reliability analysis conducted with the Turkish version of the scale, the Cronbach alpha coefficient was obtained as 0.851 for the post-pandemic health promotion behavior. Additionally, the scale was rated as reliable with the following Cronbach alpha values: 0.79 for the "personal hygiene", 0.78 for "dietary habits", 0.72 for "using mobile devices", 0.70 for "emotional health", 0.68 for "health care and physical activity", and 0.51 for "social health" sub-dimensions. To examine the six sub-dimension factor structures of the scale, fit indices were calculated as χ2/df (1.722), GFI (0.894), IFI (0.908), TLI (0.892), CFI (0.907), RMSEA (0.048), and SRMR (0.057) and were within acceptable limits. Findings of the multi-group confirmatory factor analysis for measurement invariance were less than or equal to 0.01 for the ∆CFI and ∆RMSEA values across all indices. Consequently, it was observed that the item-factor structure, factor loadings, variances, covariances, and error variances of the scale were equivalent for both male and female young adults, while test-retest results showed a high positive correlation. CONCLUSIONS: The Turkish version of the post-pandemic health promotion behavior scale of young adults in the digital age scale, consisting of 25 items and six subscales, was proven to be a valid and reliable tool to measure health promotion behavior in young adults aged 19-29 years.

RESUMEN

Introduction: Teleneuropsychology, which includes the remote application of neuropsychological tests to patients via telephone or videoconferencing, can expand access to health services for patients who reside in distant areas or have mobility restrictions. With the emergence of the COVID-19 pandemic, there has been a significant increase in the use of teleneuropsychology in cognitive assessment. In this review, the aim was to critically review the results of studies conducted in the field of teleneuropsychology and the fundamental principles related to tele-neuropsychological assessment. Additionally, the "guideline for home-based teleneuropsychology" developed for Türkiye's practices is outlined in this review. Method: A literature search was conducted using the Web of Science and PubMed databases to include all types of articles related to the subject. Results: The results of studies on in-clinic and home-based teleneuropsychological assessment indicate that tests that assess cognitive functions such as attention, memory, executive functions, and language, particularly those based on verbal administration, can be reliably applied through teleneuropsychological assessment. However, there are factors to consider when referring patients for teleneuropsychological assessment, selecting tests for assessment, and making ethical considerations. Additionally, it is important to follow recommended steps for both the clinician and the patient and/or their caregiver before and during the interview in order for the assessment to be carried out effectively. Conclusion: Although direct contact with the patient is an essential element in clinical neuropsychology practice, when necessary, teleneuropsychological assessment performed by trained experts following appropriate application procedures can be a good alternative to face-to-face evaluations.

RESUMEN

To accelerate medical breakthroughs, the All of Us Research Program aims to collect data from over one million participants. This report outlines processes used to construct the All of Us Social Determinants of Health (SDOH) survey and presents the psychometric characteristics of SDOH survey measures in All of Us. A consensus process was used to select SDOH measures, prioritizing concepts validated in diverse populations and other national cohort surveys. Survey item non-response was calculated, and Cronbach's alpha was used to analyze psychometric properties of scales. Multivariable logistic regression models were used to examine associations between demographic categories and item non-response. Twenty-nine percent (N = 117,783) of eligible All of Us participants submitted SDOH survey data for these analyses. Most scales had less than 5% incalculable scores due to item non-response. Patterns of item non-response were seen by racial identity, educational attainment, income level, survey language, and age. Internal consistency reliability was greater than 0.80 for almost all scales and most demographic groups. The SDOH survey demonstrated good to excellent reliability across several measures and within multiple populations underrepresented in biomedical research. Bias due to survey non-response and item non-response will be monitored and addressed as the survey is fielded more completely.

RESUMEN

Preschool teachers' perceptions about relationships with students (teacher-child relationships [TCRs]) predict children's subsequent social competence (SC) and academic progress. Why this is so remains unclear. Do TCRs shape children's development, or do child attributes influence both TCRs and subsequent development? Relations between TCRs and other measures were examined for 185 preschoolers (107 girls, 89 longitudinal, and ~75% European American). Teachers rated TCRs and child social/affective behaviors. Teacher-child interactions (TCIs) and children's affect expressiveness were observed. Child SC and receptive vocabulary were assessed. TCRs were significantly correlated with each type of outcome. TCIs, SC, expressed affect, and teacher-rated behaviors also predicted TCRs longitudinally. Results suggest that TCR ratings predict subsequent adaptation because they summarize children's behavioral profiles rather than on TCR quality per se.

RESUMEN

The Covid-19 pandemic, which has been affecting the world since December 2019, has become one of the biggest problems of the 21st century. There are studies stating that the contagiousness of the Covid-19 pandemic, which is transmitted from person to person, increases more with environmental factors such as air pollution, and accordingly, there is an increase in the number of cases. In this study, a panel regression model to investigate the effect of air pollution concentrations such as PM10 and SO2 as environmental factors and population density on the monthly mean number of Covid-19 cases for 12 regions at the nomenclature of territorial units for statistics (NUTS) level 1 in Turkey between June 2020 and November 2020, and a linear regression model to investigate the effect at the regional level. we used. Based on the model results, we concluded that a small increase in air pollution indicators led to an increase in the number of Covid-19 cases in Turkey and its regions. It is very important to identify preventable environmental factors in order to prevent and minimize the effects of respiratory tract diseases and rapidly spreading pandemic diseases such as Covid-19. Accordingly, we can conclude that countries should take some measures, especially on air pollution, in order to develop public health and pandemic/disease management strategies and to reduce the risk of respiratory diseases.

RESUMEN

Since pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis, epidemiological and clinical data on the disease are scarce. In this single-center retrospective study, we aim to evaluate the clinical characteristics, underlying systemic associations and treatment modalities in patients with PG in a university hospital between 2014 and 2022. It is known that PG most commonly affects the lower extremities, but extracutaneous involvement should also be kept in mind. PG is usually associated with various comorbidities that share a similar inflammatory pathogenesis with the disease. The prevalence of PG-related comorbidities varies in different studies, arthritis and solid organ malignancies were observed most frequently in the current study. Non-PG-related comorbidities including diabetes mellitus, hypertension and peripheral vascular disease can adversely affect wound healing and limit treatment options; therefore, a holistic approach to patients with PG is crucial. Consistent with literature, the mainstay of treatment for PG is systemic corticosteroids and cyclosporine. However, the implementation of biologic agents in treatment-resistant patients is an increasingly important issue in the literature. Antitumor necrosis factors (anti-TNFs) are the most commonly preferred biological therapies, and these agents seem to have paved the way for a paradigm shift in the treatment of PG. In the present study, a relatively high per cent of (23.3%) patients treated with anti-TNFs, most commonly infliximab (87.5%). Recurrence was observed in 46.7% of our patients in the follow-up period and the relapse rate was found to be higher in patients using multiple systemic agents compared to those using single agents (64.7% vs 23.1%, P < .05). In conclusion, we emphasize that early diagnosis and treatment by considering the patient's comorbidities are important in preventing complications, and biologic treatments seem particularly promising in treatment-resistant patients.

RESUMEN

OBJECTIVE: The aim of the current study was to investigate affective personality traits in Alzheimer's disease, a neurodegenerative condition mainly characterized by episodic memory impairment. METHOD: The sample included 69 participants from 3 diagnostic categories. Twenty-five participants were diagnosed with subjective cognitive impairment (SCI), 26 participants were diagnosed with mild cognitive impairment of the amnestic type (aMCI), and the remaining 18 participants were diagnosed with early-stage Alzheimer's dementia (ADD). Diagnostic labels were given as a result of detailed neurological, neuropsychological, and neuroradiological assessment. Affective personality traits were assessed via Affective Neuroscience Personality Scales (ANPS). RESULTS: The only significant intergroup difference was obtained for the SEEKING subscale of ANPS. Here, ADD group scored significantly lower compared to the SCI group. The results of logistic regression analysis also indicated that SEEKING score successfully predicted early-stage ADD diagnosis. CONCLUSION: The results suggest that a specific personality constellation characterized by reduced investment in the outside world might be associated with Alzheimer's disease, either as a risk factor or a byproduct of the neurodegenerative process initiated by AD pathology.

RESUMEN

Eating is experienced as an emotional social activity in any culture. There are factors that influence the emotions felt during food consumption. The emotion felt while eating has a significant impact on our lives and affects different health conditions such as obesity. In addition, investigating the emotion during food consumption is considered a multidisciplinary problem ranging from neuroscience to anatomy. In this study, we focus on evaluating the emotional experience of different participants during eating activities and aim to analyze them automatically using deep learning models. We propose a facial expression-based prediction model to eliminate user bias in questionnaire-based assessment systems and to minimize false entries to the system. We measured the neural, behavioral, and physical manifestations of emotions with a mobile app and recognize emotional experiences from facial expressions. In this research, we used three different situations to test whether there could be any factor other than the food that could affect a person's mood. We asked users to watch videos, listen to music or do nothing while eating. This way we found out that not only food but also external factors play a role in emotional change. We employed three Convolutional Neural Network (CNN) architectures, fine-tuned VGG16, and Deepface to recognize emotional responses during eating. The experimental results demonstrated that the fine-tuned VGG16 provides remarkable results with an overall accuracy of 77.68% for recognizing the four emotions. This system is an alternative to today's survey-based restaurant and food evaluation systems.

RESUMEN

BACKGROUND/AIM: Recent studies imply the significance of promoter CpG methylation as a biomarker for various cancer types in different genes. ALX3 is one of the candidate genes with prominent promoter methylation status change. In this study, the methylation status of ALX3 gene promoter and its expression was analyzed in lung cancer cell lines and clinical samples from The Cancer Genome Atlas Program (TCGA) program. MATERIALS AND METHODS: Methylation status was screened using the COBRA Assay, and gene expression in two cancer (A549 & H1299) and one normal (Beas 2B) lung cell lines was determined using RT-PCR. RESULTS: ALX3 gene promoter was found to be hypermethylated in both lung cancer cell lines compared to normal cells. However, no difference in the expression of this gene was observed. In addition to our in vitro findings, DNA Methylation and RNA-seq data of 413 adenocarcinoma samples from TCGA-LUAD dataset were analyzed. ALX3 gene was found to be hypermethylated in tumor compared to normal samples. Interestingly, the expression level of ALX3 gene in tumors was found to be higher than that in normal samples. CONCLUSION: ALX3 gene promoter hypermethylation could serve as a biomarker in lung cancer.

RESUMEN

INTRODUCTION: Various psychotherapies have been applied to individuals who have been subjected to torture and severe human rights violations. However, studies assessing the ef-fectiveness of such therapies are limited. Psy-choanalytic psychotherapy is said to be used frequently in practice for these patient groups. Yet, there are scarcely any studies assessing its efficacy. In this study, we aim to assess the effectiveness of psychoanalytic psychotherapy in patients with PTSD associated with torture and severe human rights violations. METHODS: 70 patients who were diagnosed with PTSD due to being tortured and severe human rights violations in accordance with DSM-IV-TR and who applied to the Human Rights Foundation of Turkey were given psy-choanalytic psychotherapy. CGI-S and CGI-I scales were applied to the patients (in Months 1, 3, 6, 9, and 12); and the patients' continu-ity of therapy and the changes in their recov-ery during the one-year psychotherapy period were assessed. RESULTS: 38 (54.3%) of the patients were female. Their mean age was 37.7 years (SD= 12.25), while their mean baseline CGI-S score was 4.67. The drop-out rate was 34%. The mean length of treatment was 21.9 ses-sions (SD = 20.30). Mean scores for CGI-I scale were 3.46, 2.95, 2.23, 2.00, and 1.54 for months 1, 3, 6, 9 and 12 respectively. As the number of sessions increased, the final CGI-I scores of the patients improved significantly towards recovery.75.4% of the pa-tients benefited from the treatment in general according to their final CGI-I score. CONCLUSIONS: Considering the limited liter-ature in the field, this study has provided sig-nificant data on the effectiveness of the use of psychoanalytic psychotherapy in individuals diagnosed with PTSD related to torture and severe human rights violations, despite its lim-itations such as not involving a control group, not having been conducted blindly and ran-domized and being based on a single scale.

RESUMEN

The Covid-19 pandemic caused uncertainties in many different organizations, institutions gained experience in remote working and showed that high-quality distance education is a crucial component in higher education. The main concern in higher education is the impact of distance education on the quality of learning during such a pandemic. Although this type of education may be considered effective and beneficial at first glance, its effectiveness highly depends on a variety of factors such as the availability of online resources and individuals' financial situations. In this study, the effectiveness of e-learning during the Covid-19 pandemic is evaluated using posted tweets, sentiment analysis, and topic modeling techniques. More than 160,000 tweets, addressing conditions related to the major change in the education system, were gathered from Twitter social network and deep learning-based sentiment analysis models and topic models based on latent dirichlet allocation (LDA) algorithm were developed and analyzed. Long short term memory-based sentiment analysis model using word2vec embedding was used to evaluate the opinions of Twitter users during distance education and also, a topic model using the LDA algorithm was built to identify the discussed topics in Twitter. The conducted experiments demonstrate the proposed model achieved an overall accuracy of 76%. Our findings also reveal that the Covid-19 pandemic has negative effects on individuals 54.5% of tweets were associated with negative emotions whereas this was relatively low on emotion reports in the YouGov survey and gender-rescaled emotion scores on Twitter. In parallel, we discuss the impact of the pandemic on education and how users' emotions altered due to the catastrophic changes allied to the education system based on the proposed machine learning-based models.

RESUMEN

A description of the skeletal development of ranids is scarce despite being well known in the family Ranidae. Herein, the description of several species of two genera representing the family Ranidae from Turkey is studied wherein the larval and adult cranial skeletons of Pelophylax caralitanus are described and compared with that of the water frog (Pelophylax bedriagae) and mountain frog (Rana macrocnemis). The data are based on cleared and double-stained specimens of 20 Gosner developmental Stages (26-46). The first element to ossify in P. caralitanus is the parasphenoid (Stage 30), followed by the exoccipitals (Stage 34) and prootics (Stage 35). The metamorphic climax commences at Stage 42 during which several modifications to the chondrocranium will unfold. In addition, ranids demonstrate remarkable differences between the water (Pelophylax sp.) and mountain (Rana sp.) frog species: (a) the ventromedial bridge between the corpora of the suprarostral cartilage in the larval upper jaw, (b) the number of processes of the central corpus in the hyobranchial skeleton, and (c) the differences in the ossification time and sequence between Pelophylax sp. and Rana sp. A detailed description of the larval osteological features of P. caralitanus conforms to the current phylogenetic position and provides a model for comparison with other ranids.
