An analysis of age-standardized suicide rates in Muslim-majority countries in 2000-2019
(BMC Public Health, 2022) Zeyrek-Rios, Emek Yüce; Bob Lew; Lester, David; Kõlves, Kairi; Yip, Paul S. F.; Ibrahim, Norhayati
Background: This study examines the 20-year trend of suicide in 46 Muslim-majority countries throughout the world and compares their suicide rates and trends with the global average. Ecological-level associations between the proportion of the Muslim population, the age-standardized suicide rates, male-to-female suicide rate ratio, and the Human Development Index (HDI) in 2019 were examined. Methods: Age-standardized suicide rates were extracted from the WHO Global Health Estimates database for the period between 2000 and 2019. The rates in each country were compared with the age-standardized global average during the past 20 years. The countries were further grouped according to their regions/sub-regions to calculate the regional and sub-regional weighted age-standardized suicide rates involving Muslim-majority countries. Correlation analyses were conducted between the proportion of Muslims, age-standardized suicide rate, male: female suicide rate ratio, and the HDI in all countries. Joinpoint regression was used to analyze the age-standardized suicide rates in 2000-2019. Results: The 46 countries retained for analysis included an estimated 1.39 billion Muslims from a total worldwide Muslim population of 1.57 billion. Of these countries, eleven (23.9%) had an age-standardized suicide rate above the global average in 2019. In terms of regional/sub-regional suicide rates, Muslim-majority countries in the Sub-Saharan region recorded the highest weighted average age-standardized suicide rate of 10.02/100,000 population, and Southeastern Asia recorded the lowest rate (2.58/100,000 population). There were significant correlations between the Muslim population proportion and male-to-female rate ratios (r=-0.324, p=0.028), HDI index and age-standardized suicide rates (r=-0.506, p<0.001), and HDI index and male-to-female rate ratios (r=0.503, p<0.001) in 2019. Joinpoint analysis revealed that seven Muslim-majority countries (15.2%) recorded an increase in the average annual percentage change regarding age-standardized suicide rates during 2000-2019. Conclusions: Most Muslim-majority countries had lower age-standardized suicide rates than the global average, which might reflect religious belief and practice or due to Muslim laws in their judicial and social structure which may lead to underreporting. This finding needs further in-depth country and region-specific study with regard to its implication for public policy.

Ancient DNA from Mesopotamia suggests distinct Pre-Pottery and Pottery Neolithic migrations into Anatolia
(Science, 2022) Acar, Ayşe; Lazaridis, Iosif; Alpaslan-Roodenberg, Songül; Açıkkol, Ayşen; Agelarakis, Anagnostis; Davtyan, Ruben
We present the first ancient DNA data from the Pre-Pottery Neolithic of Mesopotamia (Southeastern Turkey and Northern Iraq), Cyprus, and the Northwestern Zagros, along with the first data from Neolithic Armenia. We show that these and neighboring populations were formed through admixture of pre-Neolithic sources related to Anatolian, Caucasus, and Levantine hunter-gatherers, forming a Neolithic continuum of ancestry mirroring the geography of West Asia. By analyzing Pre-Pottery and Pottery Neolithic populations of Anatolia, we show that the former were derived from admixture between Mesopotamian-related and local Epipaleolithic-related sources, but the latter experienced additional Levantine-related gene flow, thus documenting at least two pulses of migration from the Fertile Crescent heartland to the early farmers of Anatolia.

Animals and pastoral groups in the mountainous Ömerli district of Southeast Anatolia
(Taylor and Francis Ltd., 2020) Sıddıq, Abu Bakar; Şanlı, Süleyman
Southeast Anatolia has been an ideal place for pastoralism since the Neolithic period. However, there is a lack of information on human–animal relationships from both archaeological settlements and contemporary societies in the region. Through ethnographic fieldwork and exploratory case studies in the mountainous Ömerli district, we explored the dependency and complex relationships between pastoral groups and various animal species in Southeast Anatolia. The case studies revealed affectionate and emotional bonds between shepherds and some individuals of domestic herds, similar to pet–human relationships in urban societies. Shepherds gave human names to certain animals; sometimes these were the names of their close friends or the names of their own children. Grief and prolonged grief was also common among Ömerli shepherds following the loss, death, or sale of these emotionally bonded animals. It was further observed that a single species (domestic or wild) often had complex and multi-purpose relationships with shepherd groups. While tortoises and hares, for instance, were used as sources of meat, the bone, blood, intestine, skin, and shell of these species were often used in traditional medicine. Although pastoral groups are completely dependent on domestic herds for their basic subsistence, Ömerli shepherds were observed to be regular hunters. It appears that the economic benefits were not the only promoters for pastoral subsistence in the study area; compassion and emotional affection for particular animals also reinforced enthusiasm for the practice. Therefore, it can be argued that the data obtained from pastoral villages in the mountainous Ömerli district help us understand interactions and relationships between humans and nonhuman animals in pastoral societies of Southeast Anatolia.

Bodily Boundaries Transgressed: Corporal Alteration Through Ornamentation in the Pre-Pottery Neolithic at Boncuklu Tarla, Turkiye
(Cambridge Univ Press, 2024) Kodas, Ergul; Baysal, Emma L.; Ozkan, Kazim
Lack of contextual evidence for the use of small personal ornaments means that much of our understanding of ornamentation traditions within archaeological cultures is reconstructed from ethnographic comparisons. New in situ finds from the areas around the ears and mouth in burials at Boncuklu Tarla, a Neolithic settlement in Turkiye, add a novel dimension to the interpretation of stone 'tokens' or 'plugs'. This article presents a new typology for these artefacts and argues for their use as ear ornaments or labrets in a practice involving significant and lasting corporal alteration.

Bronchiectasis in Türkiye: Data From a Multicenter Registry (Turkish Adult Bronchiectasis Database)
(Galenos Publ House, 2024) Edis, Ebru Cakir; Cilli, Aykut; Kizilirmak, Deniz; Coskun, Ayson Sakar; Guler, Nurcan; Cicek, Sedat; Sayiner, Abdullah; Gülmez, İnci; Çağlayan, Benan; Niksarlioglu, Elif Yelda Ozgun; Researchers, Tebveb
Background: Bronchiectasis is a chronic lung disease characterized by permanent bronchial wall dilatation. Although it has been known as an orphan disease, it has recently gained attention because of registry -based studies and drug research. Aims: We aimed to use a multicenter database to analyze and compare data regarding the etiology, associated comorbidities, microbiological characteristics, and preventive strategies of bronchiectasis in T & uuml;rkiye to those of other countries. Study Design: A multicenter prospective cohort study. Methods: The multicenter, prospective cohort study was conducted between March 2019 and January 2022 using the Turkish Adult Bronchiectasis Database, in which 25 centers in T & uuml;rkiye participated. Patients aged > 18 years who presented with respiratory symptoms such as cough, sputum, and dyspnea and were diagnosed with non -cystic fibrosis bronchiectasis using computed tomography were included in the study. Demographic information, etiologies, comorbidities, pulmonary functions, and microbiological, radiological, and clinical data were collected from the patients. Results: Of the 1,035 study participants, 518 (50%) were females. The mean age of the patients was 56.1 +/- 16.1 years. The underlying etiology was detected in 565 (54.6%) patients. While postinfectious origin was the most common cause of bronchiectasis (39.5%), tuberculosis was identified in 11.3% of the patients. An additional comorbidity was detected in 688 (66.5%) patients. The most common comorbidity was cardiovascular disease, and chronic obstructive pulmonary disease (COPD) and bronchiectasis was identified in 19.5% of the patients. The most commonly detected microbiological agent was Pseudomonas aeruginosa (29.4%). Inhaled corticosteroids (ICS) were used in 70.1% of the patients, and the frequency of exacerbations in the last year was significantly higher in patients using ICS than in nonusers (p < 0.0001). Age [odds ratio (OR): 1.028; 95% confidence interval (CI): 1.005-1.051], cachexia (OR: 4.774; 95% CI: 2,054-11,097), high modified medical research council dyspnea scale score (OR: 1,952; 95% CI: 1,459-2,611), presence of chronic renal failure (OR: 4,172; 95% CI: 1,249-13,938) and use of inhaled steroids (OR: 2,587; 95% CI: 1,098-6,098) were significant risk factors for mortality. Mortality rates were higher in patients with COPD than in those with no COPD (21.7-9.1%, p = 0.016). Patients with bronchiectasis and COPD exhibited more frequent exacerbations, exacerbation -related hospitalizations, and hospitalization in the intensive care unit in the previous year than patients without COPD. Conclusion: This is the first multicenter study of bronchiectasis in T & uuml;rkiye. The study results will provide important data that can guide the development of health policies in T & uuml;rkiye on issues such as infection control, vaccination, and the unnecessary use of antibiotics and steroids.
Byzantium in the Iconoclast Era, c.680-850: A History
(OXFORD UNIV PRESS, 2012) Krausmüller, Dirk
Although the title refers to the period between 680 and 850 as the ‘Iconoclast era’, the main aim of this book is to demonstrate that previous scholarship has exaggerated the importance of the controversy about religious images. The authors argue, firstly, that Iconoclasm was only one aspect in a much broader process of transformation, and secondly, that Iconoclasm itself was less significant than Iconophile sources would have us believe. The book is clearly intended to be a comprehensive treatment of the period. Owing to the specialisations of the two authors, the focus is on art history and on social, economic and administrative history, whereas literature is barely mentioned.

Can deep learning replace histopathological examinations in the differential diagnosis of cervical lymphadenopathy?
(Springer, 2024) Can, Sermin; Türk, Ömer; Ayral, Muhammed; Kozan, Günay; Arı, Hamza; Akdağ, Mehmet; Yıldırım Baylan, Müzeyyen; Baylan, Muezeyyen Yildirim
Introduction: We aimed to develop a diagnostic deep learning model using contrast-enhanced CT images and to investigate whether cervical lymphadenopathies can be diagnosed with these deep learning methods without radiologist interpretations and histopathological examinations. Material method: A total of 400 patients who underwent surgery for lymphadenopathy in the neck between 2010 and 2022 were retrospectively analyzed. They were examined in four groups of 100 patients: the granulomatous diseases group, the lymphoma group, the squamous cell tumor group, and the reactive hyperplasia group. The diagnoses of the patients were confirmed histopathologically. Two CT images from all the patients in each group were used in the study. The CT images were classified using ResNet50, NASNetMobile, and DenseNet121 architecture input. Results: The classification accuracies obtained with ResNet50, DenseNet121, and NASNetMobile were 92.5%, 90.62, and 87.5, respectively. Conclusion: Deep learning is a useful diagnostic tool in diagnosing cervical lymphadenopathy. In the near future, many diseases could be diagnosed with deep learning models without radiologist interpretations and invasive examinations such as histopathological examinations. However, further studies with much larger case series are needed to develop accurate deep-learning models.

A cat skeleton from the balatlar church excavation, sinop, Turkey
(MDPI AG, 2021) Sıddıq, Abu Bakar; Onar, Vedat; Köroğlu, Gülgün; Armutak, Altan; Öncü, Öğül Emre; Chrószcz, Aleksander
In the 2015 excavation season, an east–west oriented burial (2015-Grave-14) built with large dimension stone blocks was unearthed on the south edge of “Area IVi” at the Balatlar Church in Sinop, on the northeastern Black Sea coast of Turkey. In this grave, which is dated between the end of the 6th century AD and the first half of the 7th century AD, a human skeleton was found with the head to the west and a cat skeleton was carefully placed next to the right femur. This study on the burial and the cat skeleton within it shows that, compared to the Roman period, the status of cats reached a higher level during the Byzantine period. It was found that alongside of being a pet, the Balatlar cat was a young healthy female individual that instinctively hunted rodents and birds, given that the remains of a rat and a sparrow were found in the region of the abdominal cavity, corresponding with the stomach location in the living animal. The grave presents the most significant direct archaeological evidence of a pet–human bond recorded at any Byzantine site so far.

Changes in volatile compounds, sugars and organic acids of different spices of peppers (Capsicum annuum L.) during storage
(FOOD CHEMISTRY, 2020) Korkmaz, Aziz; Atasoy, Ahmet Ferit; Hayaloglu, Ali Adnan
Changes in sugars, organic acids and volatile compounds (VC) of red pepper flakes (RPF), traditional (TRI), and industrial (INI) isot peppers were evaluated during one year storage at the room condition. The changes in the flavor components were significantly affected by the production methods and storage time. Glucose content decreased gradually along storage and reduced by about 21.23, 47.22 and 56.65% for TRI, INI and RPF, respectively. However, fructose decreased significantly only in RPF (11.29%). Citric and succinic acids exhibited slight changes, but malic acid showed an increasing trend, especially in RPF (4-fold). Most of the VC in all samples decreased or disappeared after storage. The major quantitative losses in these compounds were found in TRI during the first 3 months as 81.76%. The storage was found to be caused deterioration flavor properties in red pepper spices and revealed the importance of appropriate storage conditions.

Chronic Maternal Tobacco Smoke Exposure and/or Alpha-Lipoic Acid Treatment Causes Long-Term Deterioration of Testis and Sexual Behavior in Adult Male Rats
(Elsevier, 2020) Yardimc, Ahmet; Ramazan Fazil Akkoc, Ahmet Tektemur, Nazife Ulker, Nalan Kaya Tektemur, Elif Erdem Güzel, Sinan Canpolat, Ibrahim Enver Ozan
Background: Tobacco use during pregnancy is known to have several negative effects on the offspring's reproductive health in the long term. The use of alpha-lipoic acid (ALA) as a dietary supplement during pregnancy has increased greatly in recent years and has been known to have positive effects on various pregnancy outcomes including miscarriage, diabetic embryopathy, preterm delivery, and congenital malformations. Aim: To evaluate the effects of tobacco smoke exposure (TSE) on sexual behavior, reproductive parameters, and testicles in adult male rats and to reveal the possible role of ALA administration on these parameters. Methods: Pregnant rats (n = 7 per group) were treated with tobacco smoke (TS), ALA (20 mg/kg), and TS + ALA for a total of 11 weeks. The following parameters were compared with 8 control rats: puberty parameters, sexual behavior; levels of serum gonadotropins and testosterone, total antioxidant status, and total oxidant status; the expression of the apoptotic protease-activating factor-1 and caspase 9 mRNA levels in the testis; and assessment of immunohistochemistry and terminal deoxynucleotidyl transferase dUTP nick end labeling assay of testis. Main Outcome Measure: Sexual behavior, changes in puberty parameters, and hormonal and genetic alterations were the outcomes analyzed in this study. Results: Maternal TSE caused a significant decrease in the number of intromissions compared to the control group. Similarly, ALA decreased erectile function in sexual behavior by decreasing the number of intromissions and intromission ratio in the ALA group compared to the control group. In addition, TSE and ALA treatment caused an impairment of some consummatory sexual behaviors. Also, in parallel with this inhibitory effect, the age of pubertal onset was significantly delayed in the TS + ALA group compared to other groups. Also, histopathological changes in testicular tissue, oxidative stress markers, apoptotic index, and mRNA levels of apoptosis-related genes increased in all treatment groups. Clinical Implications: The use of ALA and/or tobacco products during pregnancy may adversely affect the reproductive health of male newborns in the long term. Strengths & Limitations: To the best of our knowledge, this study is the first to show the effects of maternal ALA treatment and/or TSE on the sexual behavior and reproductive parameters in male rats; however, the study is based on an animal model, and the present findings partially reflect the characteristics of human sexual behavior. Conclusion: Maternal TSE and/or ALA treatment may impair sexual behavior in adulthood in male rats because of testicular damage caused by oxidative stress during gonadal development.

The Cittaslow Philosophy in the Context of Sustainable Tourism Development; The Case of Turkey
(Tourism Management, 2014) Ekinci, Mehmet Behzat
This paper studies the Cittaslow (slow city) philosophy in terms of sustainable tourism development (STD); and in this context research was undertaken for the case of Turkey. Cittaslow, a movement rooted in STD philosophy, aims to encourage the development of tranquil cities already known for their historical, natural, socio-cultural, and touristic features and the intention is to offer a significant contribution to systematic and rapid implementation of STD on a global scale. This paper, which makes a particular study of the practice of STD in Turkey, offers new candidate cities (Uzungöl, Hasankeyf, Safranbolu, Ürgüp, and İznik) and, thus, endeavours to contribute to the spread of STD throughout the whole country. In this study, above-named cities were found to be particularly good candidates for Cittaslow membership. In addition to these: Tatvan, Midyat, Alanya, and Fethiye were also found to be potential Cittaslows even though they fail to meet the population criterion.

Clinical features of generalized lipodystrophy in Turkey: a cohort analysis
(Wiley Online Library, 2023) Özbek, Mehmet Nuri; Yildirim Simsir, Ilgin; Tuysuz, Beyhan; Tanrikulu, Seher; Celik Guler, Merve; Akinci, Baris; Karhan, Asuman Nur
Aim: To describe the Turkish generalized lipodystrophy (GL) cohort with the frequency of each complication and the death rate during the period of the follow-up. Methods: This study reports on 72 patients with GL (47 families) registered at different centres in Turkey that cover all regions of the country. The mean ± SD follow-up was 86 ± 78 months. Results: The Kaplan-Meier estimate of the median time to diagnosis of diabetes and/or prediabetes was 16 years. Hyperglycaemia was not controlled in 37 of 45 patients (82.2%) with diabetes. Hypertriglyceridaemia developed in 65 patients (90.3%). The Kaplan-Meier estimate of the median time to diagnosis of hypertriglyceridaemia was 14 years. Hypertriglyceridaemia was severe (≥ 500 mg/dl) in 38 patients (52.8%). Seven (9.7%) patients suffered from pancreatitis. The Kaplan-Meier estimate of the median time to diagnosis of hepatic steatosis was 15 years. Liver disease progressed to cirrhosis in nine patients (12.5%). Liver disease was more severe in congenital lipodystrophy type 2 (CGL2). Proteinuric chronic kidney disease (CKD) developed in 32 patients (44.4%) and cardiac disease in 23 patients (31.9%). Kaplan-Meier estimates of the median time to diagnosis of CKD and cardiac disease were 25 and 45 years, respectively. Females appeared to have a more severe metabolic disease, with an earlier onset of metabolic abnormalities. Ten patients died during the follow-up period. Causes of death were end-stage renal disease, sepsis (because of recurrent intestinal perforations, coronavirus disease, diabetic foot infection and following coronary artery bypass graft surgery), myocardial infarction, heart failure because of dilated cardiomyopathy, stroke, liver complications and angiosarcoma. Conclusions: Standard treatment approaches have only a limited impact and do not prevent the development of severe metabolic abnormalities and early onset of organ complications in GL.
A comparative approach to using photogrammetry in the structural analysis of historical buildings
(2024) Kutlu, İzzettin; Soyluk, Asena
Finite element method (FEM) provides the numerically solving differential equations arising in engineering and mathematical modeling of physical systems. This process begins by determining the assignment of a theoretical node. A node is a single point on a frame, shell, or solid element and each element can be programmed with its location's material and structural data. Programming with the FEM is quite time-consuming for complex geometry such as historical buildings. This study aims to examine a low-cost and time-saving technology to build a FEM model using photogrammetry. In accordance with this aim, classical modeling techniques and photogrammetric modeling techniques were discussed. The results demonstrated that similar values were revealed in stress and deformation values. Consequently, the study emphasizes the potential of photogrammetry technology as an integrated approach for bringing together the disciplines of architecture and engineering that usually require two distinct expertise in analysing the structural behavior of historical buildings.

Comparison of Growth Factor Levels in Injectable Platelet-Rich Fibrin Obtained From Healthy Individuals and Patients With Chronic Periodontitis: a Pilot Study
(BMC, 2024) Savas, Hasan Basri; Karci, Bilge
Background This study aimed to assess and compare the concentrations of growth factors, white blood cells (WBCs), and platelets in injectable platelet-rich fibrin (i-PRF) derived from people with healthy periodontal conditions and those with chronic periodontitis.Methods Venous blood samples were obtained from 30 patients diagnosed with chronic periodontitis (test group) and 30 participants with healthy periodontal conditions (control group). The i-PRF was then acquired from centrifuged blood. The growth factors (VEGF, IGF-1, TGF-beta 1, PDGF-BB and EGF) released from the i-PRF samples were compared between groups with ELISA testing. The amounts of WBCs and platelets were also compared.Results No significant differences in the concentrations of growth factors were found between the groups (the mean values for the control and test groups were, respectively: IGF: 38.82, 42.46; PDGF: 414.25, 466.28; VEGF: 375.69, 412.18; TGF-beta 1: 21.50, 26.21; EGF: 138.62, 154.82). The test group exhibited a significantly higher WBC count than the control group (8.80 vs. 6.60, respectively). However, the platelet count did not show a statistically significant difference between the groups (control group 242.0 vs. test group 262.50). No significant correlation was observed between WBC count and growth factor level in either group.Conclusions The growth factor levels in i-PRFs did not exhibit significant difference between the two groups. This suggests that the levels of these growth factors may be unaffected by the periodontal disease.

Comparison of healthcare workers and non-healthcare workers in terms of obsessive-compulsive and depressive symptoms during COVID-19 pandemic: a longitudinal case-controlled study
(Frontiers, 2023) Uyar, Betül; Dönmezdil, Süleyman
Objective: The aim of this study was to investigate the obsessive-compulsive and depressive symptoms of healthcare workers in a case-control setting as longitudinal. Method: In this study included 49 healthcare workers and 47 non-health workers. A sociodemographic data form, the Maudsley Obsessive-Compulsive Inventory (MOCI), the Symptom Checklist-90 (SCL-90), and the Hamilton Depression Rating Scale (HAM-D) were used to assess individuals between June 1, 2020 and June 30, 2021. We assessed the same healthcare workers after 12 months on June 30, 2021 using MOCI, HAM-D, and SCL-90. Results: MOCI and SCL-90 obsessive-compulsive subscale scores were significantly higher in the healthcare workers than in the non-health workers. When we assessed MOCI, HAM-D, and SCL-90 obsessive-compulsive subscale scores after 12 months, there was a statistically significant decrease in the scores of all three scales among the healthcare workers. Conclusion: The results of the study showed that healthcare workers were more likely to have obsessive-compulsive symptoms than non-health workers in the early part of the pandemic on June 1, 2020, as shown by their scores on MOCI and the obsessive-compulsive subscale of SCL-90. When we assessed the same participants after 12 months (June 30, 2021), both MOCI and SCL-90 obsessive-compulsive subscale scores had decreased significantly. In contrast to these results, HAM-D scores significantly increased.

A conceptual framework of the service delivery system design for hospitality firms in the (post-)viral world: The role of service robots
(International Journal of Hospitality Management, 2020) Seyitoğlu, Faruk; Ivanov, Stanislav
This study aims to develop a conceptual framework of the service delivery system design for hospitality firms in the (post-)viral world. Several theoretical approaches such as resource-based view, value chain analysis, stakeholder theory, PESTEL analysis, positioning strategy, and service delivery system design were adopted. The paper identified three service delivery system designs (robotic, human-based, and mixed) and analyses their requirements, advantages, disadvantages, and potential target markets. According to the suggested model, hospitality firms need first to explore the expectations of tourists. Then comes the analysis phase (based on a holistic perspective, and consisting of RBV, Value chain, Stakeholder, and PESTEL analyses), which helps hospitality firms to identify how they should differentiate and position themselves in the market. Following, companies decide on what kind of service delivery system they should offer to their target customers, and position themselves in the market according to the chosen system.

Correlation between vitamin D status and Wechsler Adult Intelligence Scale's comprehension subtest in patient with end-stage renal diseases
(WILEY-BLACKWELL, 2016) Karaoğlan, Mehmet; Emre, Memet Hanifi; Demirtaş, Yasemin; Şahin, İdris; Taşkapan, Hülya
Aim: Cognitive decline is an important problem for individuals, as well as for the community. Increasing evidence suggests that vitamin D may play a role in maintaining cognitive function and vitamin D deficiency may accelerate cognitive decline. The aim of this study was to evaluate the status of vitamin D in chronic renal failure (CRF) patients on peritoneal dialysis (PD) and to correlate the findings with cognitive functions. Materials and methods: The study was performed in Inonu University Turgut Ozal Medical Center. Serum 25hydroxyvitamin D (25(OH)D) was measured and cognitive functions (Wechsler Adult Intelligence Scale’s (WAIS) Comprehension Subtest) tested with 51 peritoneal dialysis patients and a control group consisting of 51 healthy individuals have similar conditions with patients. Individuals with other chronic diseases and smoking and alcohol habits which may impair cognitive functions were excluded from the study. Results: Compared to each groups we found negative correlation between 25(OH)D3 levels and WAIS’s Comprehension Subtest in patient and control group. The correlation between data was evaluated with the Spearman’s test (P = 0.597, r = 0.76 and P = 0.010 r = 0.356 respectively). Conclusions: In the literature, there is no consensus on the presence of an association between vitamin D levels and cognition. In this study vitamin D levels were measured as deficiency in both groups. Further studies are needed to investigate for increasing actual knowledge about this association.
