Algae biomass could be one of the most important economic values in near future. For this reason, we determined the biochemical compositions and molecular weight profiles (MWPs) of eight macroalgae; Green Algae (Codium fragile, Ulva intestinalis, Chaetomorpha linum, and Codium bursa), Red Algae ( Ellisolandia elongata, Jania rubens, and Amphiroa rigida), Brown Algae (Padina pavonica) collected from different regions in Turkey. The differences measured between biochemical compositions such as ash, lipid, and protein of macroalgae species were statistically significant (P. The lowest levels of MWP belonging to the macroalgae was observed in 2532-13000 Da except for Ulva intestinalis and Padina pavonica belonging to 67000 Da were similar to each other except for Ulva intestinalis. The 13700 - 67000 Da and 2532-13000 Da levels belonging to Ulva intestinalis were higher than those of other tested macroalgae. However, level of Ulva intestinalis (67000 Da

- Abstract
Objectives: to investigate the effect of the novel coronavirus disease 2019 (COVID-19) pandemic on the clinical practice of ophthalmologists in our country. Materials and methods: a questionnaire consisting of 22 questions was delivered to 250 ophthalmologists via e-mail and a smartphone messaging application. A total of 113 ophthalmologists completed the survey. The questions included the participants’ demographic data (age, years in practice, institution, and city), changes in their working conditions and institutional preventive measures implemented during the pandemic, their personal COVID-19 experiences, the prevalence of telemedicine applications, and their attitudes toward these practices. Results: nearly half (47.8%) of the 113 ophthalmologists were 36 to 45 years old. In terms of years in practice, the largest proportion of respondents (28.3%) had 6-10 years of experience. Most of the participants worked in private/foundation universities (37.2%), while 22.1% worked in education and research clinics. Participants working at public universities most often reported that they or a close contact had to work in COVID wards (89.5%). Triage was performed in 51.5% of ophthalmology outpatient clinics, with 88.0% of these participants reporting that patients with fever, cough, or dyspnea were directed to the pandemic clinic without ophthalmological examination. All participants working in public hospitals, education and research clinics, and public university hospitals had postponed elective surgeries, whereas 12.5% of those working in private practice and 20.5% of those working in private/foundation universities reported that they continued elective surgeries. While 80.8% of the participants did not conduct online interviews or examinations, 40.4% stated that they considered telemedicine applications beneficial. Seventy-seven percent of participants expressed concern about a decrease in their income during the pandemic, with this being especially common among partic, NA

Background: The aim of our study is to investigate the relationship between chronotypes and impulsivity, attention-deficit disorder and smartphone, social media, and internet addiction in a sample of university students. Method: The study was conducted at our university from May to July 2021. A total of 255 subjects were recruited in the study among the students from the medical faculty and the faculty of health sciences (departments of nutrition and dietetics, nursing, and physiotherapy and rehabilitation) of our university who received face-to-face education in 2020-2021. Sociodemographic data form, the Adult Attention-Deficit/Hyperactivity Disorder Self-Report Scale, Morningness-Eveningness Questionnaire, Barratt Impulsiveness Scale-11 Short Form, Young's Internet Addiction Scale, Social Media Addiction Scale-Adult Form, and Smartphone Addiction Scale-Short Version were administered by the study investigators through face-to-face interviews. Results: Among the students, the intermediate type was most common (n = 157) and the evening type was least common (n = 44). The chronotypes differed in terms of the time spent daily on smartphone and internet (P = .001 and P < .001). The evening types showed significantly higher mean scores on the Adult Attention-Deficit/Hyperactivity Disorder Self-Report Scale, Morningness-Eveningness Questionnaire, Barratt Impulsiveness Scale-11 Short Form, Young's Internet Addiction Scale, Social Media Addiction Scale-Adult Form, and Smartphone Addiction Scale-Short Version when compared with other chronotypes. Female and male students showed comparable scores on all scales. Chronotypes were not different between genders. Conclusions: The results of our study showed a greater frequency of smartphone, internet, and social media addiction among the evening types than in the other chronotypes. Greater impulsivity and attention problems as observed in the evening types may be predisposing these individuals to develop addiction to smartphone, internet, and social media.

Objective: The purpose of this study was to establish the reliability of the Turkish translation of the Hammersmith Infant Neurological Examination in infants at 8-12 months corrected age and compare Hammersmith Infant Neurological Examination scores to other predictive assessments. Materials and Methods: Perinatal risk factors, term-age magnetic resonance imaging, general movements at 3-month corrected age, and 12-month corrected age The Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III) scores were obtained in 35 high-risk infants. The Hammersmith Infant Neurological Examination was evaluated using intra-rater and interrater reliability. Hammersmith Infant Neurological Examination scores were compared to the findings from the three other assessments. Results: Intra-rater and inter-rater reliability was high (intraclass correlation coefficient = 1.00; intraclass correlation coefficient = 0.969, P < .001, 95% CI = 0.939-0.984, respectively). Global Hammersmith Infant Neurological Examination scores were significantly lower in infants with magnetic resonance imaging evidence of brain injury than without (P < .05) and in infants without general movements Fidgety movements (P < .05), than with. There was a significant positive correlation between global Hammersmith Infant Neurological Examination scores and Bayley Scales-III cognitive (P < .001), language (P < .001), and motor composite scores (P < .001). Conclusion: This study strongly supports the use of the Turkish translation of the Hammersmith Infant Neurological Examination. Users found it readily understandable and easy to use, and the scores were consistent with 3 different methods of predicting neurodevelopmental outcomes. These findings will aid the early diagnosis, management, and support for children with neurodevelopmental problems. [ABSTRACT FROM AUTHOR]

Bu çalışmada fibromiyalji hastalarının D vitamini seviyeleri ile hastalık şiddeti ve enflamasyonla ilişkisini nötrofil lenfosit oranı (N/L), platelet lenfosit oranı (P/L), ortalama trombosit hacmi (OTH), eritrosit sedimentasyon hızı (ESH) ve C-reaktif protein (CRP) parametrelerini kullanarak değerlendirme ve klinik önemini araştırma amaçlanmıştır. Çalışmaya SANKO Üniversitesi Uygulama ve Araştırma Hastanesi Fizik Tedavi ve Rehabilitasyon Polikliniğine başvurmuş fibromiyaljili hastalar ve sağlıklı kontroller dahil edildi. Fibromiyalji hastalarının fonksiyonel durumunu değerlendirmek için Fibromiyalji Etki Anketi kullanıldı. Hastalara ait demografik ve laboratuvar bilgileri retrospektif olarak dosya taraması ile elde edildi. Fibromiyalji (n=51) ve kontrol (n=46) grubu arasında cinsiyet ve yaş bakımından istatistiksel olarak anlamlı b ir f ark y oktu ( sırasıyla; p=1.000, p=0.074). Hasta ve kontrol gruplarının trombosit, OTH, nötrofil, lenfosit, N/L, P/L değerleri arasında istatistiksel olarak anlamlı bir fark bulunamadı (p>0.05). Fibromiyalji hastalarında D vitamini eksikliği, CRP ve ESH düzeylerindeki yükseklik istatistiksel olarak anlamlı bulunurken (sırasıyla p0.05). Çalışmamız her iki grupta D vitamini eksikliğinin hastalık şiddeti ve trombosit, OTH, N/L, P/L, ESH, CRP değerleri arasında anlamlı bir ilişki olmadığını ortaya koydu. Fibromiyalji sendromunda D vitamini ile enflamasyon belirteçlerinin ve hastalık şiddetinin arasındaki ilişkiyi değerlendirmek için daha geniş çaplı çalışmalara ihtiyaç vardır. In this study, it is aimed to evaluate the relationship between vitamin D levels and disease severity and inflammation parameters using neutrophil lymphocyte ratio (N/L), platelet lymphocyte ratio (P/L), mean platelet volume (MPV), erythrocyte sedimentation rate (ESR) and Creactive protein (CRP) in fibromyalgia patients and to examine the clinical significance of it. Patients with fibromyalgia and healthy controls who applied to SANKO University Research and Application Hospital Physical Therapy and Rehabilitation Outpatient Clinic were included. The Fibromyalgia Impact Questionnaire was used to evaluate the functional status of patients with fibromyalgia. The demographic and laboratory data of the patients were retrospectively obtained. There was no statistically significant difference in age (p=1.000, p = 0.074) and in gender fibromyalgia (n=51) and controls (n=46). There was no statistically significant difference between patients with fibromyalgia and healthy controls in platelet, MPV, neutrophil, lymphocyte, N/L, P/L values (p>0.05). Vitamin D deficiency and high CRP and ESR levels was statistically significant in fibromyalgia patients (p0.05). There was no significant relationship between vitamin D deficiency and disease severity and platelet, MPV, N/L, P/L, ESR, CRP values of in both groups. Larger studies are needed to evaluate the relationship between vitamin D and inflammation markers and disease severity in fibromyalgia syndrome.

Background: The aim of this study was to examine the clinical characteristics and quality of life (QOL) of patients with BCRL (breast cancer-related lymphedema). Methods: In this cross-sectional descriptive study, patients' characteristics such as age, body mass index (BMI: kg/m²), history of chemotherapy (CT), radiotherapy (RT), hormone replacement therapy (HRT), neoadjuvant therapy (NT), cancer stages, and types of surgery were recorded. Patients were evaluated using the 'Disabilities of the Arm, Shoulder and Hand questionnaire' (DASH), the 'Lymphedema Quality of Life Questionnaire' (LYMQOL-ARM), and a visual analogue scale (VAS). Results: A total of 68 women with the mean age of 52.50±9.33 and BMI 29.240 ± 5.05 kg/m² were recruited after breast cancer surgery in this study: thirty-three patients (48.5%) in Stage 0; 24 (35.3%) in Stage 1; 10 (14.7%) in Stage 2; and 1 (1.5%) in Stage 3. No statistically significant difference was found in the QOL according to treatments received after the diagnosis of breast cancer surgery, RT (except the appearance domain of QOL), CT, HRT, or NT. In patients who had received axillary dissection in combination with RT, a statistically significant association was observed between QOL related to body image and symptoms (p=0.009 and p=0.017, respectively). A statistically significant difference was found only in body image and clinical symptom domains according to the lymphedema stage (p=0.027 and p=0.002, respectively). It was observed that as shoulder pain (VAS) and disability (DASH) scores increased, scores of all domains of QOL increased except the overall domain in QOL (p<0.05). Conclusion: It was observed that clinical symptoms and body image parameters in QOL were associated with the lymphedema stage and the number of lymph nodes dissected. It was concluded that axillary dissection with axillary RT and RT alone after breast cancer surgery is associated with body image. Our study revealed that body image perception is related to the quality of life in patients with BCRL. Optimal management of the negative effects of self-reported lymphedema evaluated in the latency phase on quality of life requires coordination between Physical Medicine and Rehabilitation and General Surgery Clinics.

Sağkalım Analizi'nde araştırmacılar bir taraftan bir topluluğun sağkalım olasılığını kestirmeyi amaçlarken diğer bir taraftan da farklı grupların sağkalım olasılıklarını karşılaştırmak isteyebilirler. Bu durumda, sağkalım bakımından gruplar arasındaki fark iki gruba ait sağkalım eğrileri çizilerek görsel olarak değerlendirilebilir ancak bu değerlendirme yalnızca kabaca bir fikir verir. Sağkalım araştırmalarında elde edilen veriler çoğunlukla sansürlü gözlemler içerdiğinden gruplar arasında sağkalım bakımından istatistiksel olarak karşılaştırma yapmak için özel olarak tasarlanmış testlere ihtiyaç duyulmaktadır. Bu tez çalışmasında Logrank, Gehan-Wilcoxon, Tarone-Ware, Peto-Peto, Modifiye Peto-Peto testleri ile Fleming-Harrington test grubunda (p, q) değerleri; (1, 0), (0.5, 0.5), (1, 1), (0, 1) ve (0.5, 2) olan testler, ilgilenilen olayın izlem süresi boyunca eşit olasılıkla ve izlem süresinin başlarında, ortasında ya da sonlarında yoğun olarak yer aldığı durumlarda, sağkalım süresi verilerinin ise farklı dağılımlardan türetildiği durumlarda yürütülen simülasyon çalışması sonunda elde edilen Tip I hata oranı bakımından incelenmiştir. Simülasyon çalışmamızın sonuçları incelendiğinde, ilgilenilen olayın izlem süresi boyunca eşit olasılıkla yer aldığı durumda Logrank testi için Tip I hata oranının belirlenen nominal değere eşit ya da çok yakın olduğu görülmektedir. İlgilenilen olay izlem süresi başlangıcında yoğun olarak görüldüğünde Tip I hata oranları nominal değerden düşük olma eğilimi; ilgilenilen olay izlem süresi sonunda yoğun olarak bulunduğunda nominal değerden yüksek olma eğilimi göstermektedir. İlgilenilen olay izlem süresinin ortasında yoğun olarak bulunduğunda ise literatürde başlangıçtaki olaylara ağırlık verdiği belirtilen Gehan-Wilcoxon, Tarone-Ware, Peto-Peto, Modifiye Peto-Peto ve F-H(1,0) testlerinde Tip I hata oranı nominal değerden genellikle yüksek iken; diğer testlerde düşük elde edilmiştir. In Survival Analysis, on one hand investigators intend to estimate the survival probability of a population on the other hand they may want to compare the survival experiences of different groups. In such cases, the differences can be illustrated by drawing survival curves but this will only give a rough idea. Since the data obtained from survival studies contains frequently censored observations some specially designed tests are required in order to compare groups statistically in terms of survival. In this dissertation, Logrank, Gehan-Wilcoxon, Tarone-Ware, Peto-Peto, Modified Peto-Peto tests and tests belonging to Fleming-Harrington test family with (p, q) values; (1, 0), (0.5, 0.5), (1, 1), (0, 1) ve (0.5, 2) are examined by means of Type I error rate that obtained from simulation study which is conducted in the cases where the event takes place with equal probability along the follow-up time or takes place mostly at the beginning, in the middle or at the end of the follow-up time and where the survival time is generated from different distributions. As a result of simulation study, in the case of the event takes place with equal probability along follow-up time, Type I error rate of Logrank test is equal or too close to nominal value. When the event is seen frequently at the beginning of the follow-up time Type I error rate tends to be less than nominal value; when the event takes place mostly at the end of the follow-up time Type I error rate tends to be greater than nominal value. When the event appears mostly in the middle of the follow-up time, Type I error rate is greater than nominal value for the tests Gehan-Wilcoxon, Tarone-Ware, Peto-Peto, Modifiye Peto-Peto ve F-H(1,0), which are stated as giving more weight the events at the beginning; and is less than nominal value for the other tests.

Purpose: We aimed to evaluate articles in radiology journals indexed in the Science Citation Index or Science Citation Index Expanded in terms of statistical errors. By this means, we aim to contribute to the production of high quality scientific publications.Methods: In this study, a total of 157 articles published in 2016-2017 in 20 radiology journals were reviewed randomly. Selected articles were evaluated for statistical errors regarding P values and statistical tests, and for errors in terminology and other errors related to interpretation. In addition, in order to examine whether the error rates of the articles published in the radiology journals differed according to the impact factor, the statistical errors were compared according to the impact factors of the journals.Results: Of the 157 articles published in radiology journals, 10 had no statistical errors, while 147 had at least one statistical error. The most frequently encountered error was "errors in summarizing data" with a rate of 66%. This was followed by "incorrect representation of P values" with a rate of 42%. The least frequently encountered error was "statistical symbol errors" with a rate of 3%. There was no statistically significant difference according to impact factors.Conclusion: In conclusion, radiology journals, as do journals in different fields, include articles containing statistical errors. Even when the quality of the journal increases, there is no difference in these statistical error rates. In order to prevent statistical errors in manuscripts, there are responsibilities for both the researchers who conduct scientific studies and the editors who publish these studies in their journals. Researchers should have a basic statistical knowledge, and the editor must submit all manuscripts for a statistical review. [ABSTRACT FROM AUTHOR]- Published

Introduction: Ischemia-modified albumin (IMA) level increases in inflammatory conditions. We aimed to investigate the association between IMA levels and the severity of coronavirus disease 2019 (COVID-19) infection in adult patients. Methodology: We grouped adult patients with COVID-19 infection: Group A - mild symptoms, but normal computed tomography (CT), Group B - mild/moderate illness, and Group C - severe or critical illness. We measured IMA levels at the time of diagnosis of COVID-19 infection. Results: Mean age of the total number of patients (n = 90) was 54.43 (± 8.11) year, and 46.7% (n = 42) were female. IMA levels were highest in Group C and lowest in A (p < 0.001). The most important factor predicting COVID-19 disease severity was IMA. Type 2 diabetes was more frequent in Group C (n = 31) than in Group B (n = 30) (p = 0.042). Asthma was less frequent, and coronary artery disease was more frequent in Group C than in Group A (n = 29) and B (p = 0.009). Duration of hospitalization was highest in Group C (p < 0.001). Conclusions: We analyzed a sample of patients with COVID-19 infection and found that IMA predicted severe COVID-19 disease. Disease severity grouping was based on patients' clinical and radiological features. IMA level measured when SARS-CoV-2 infection is diagnosed may be a useful marker in predicting likely disease severity or intensive care need. [ABSTRACT FROM AUTHOR]

Background & Objective: The late-term neurological effects of COVID-19 are not fully understood yet. Herein, we aimed to determine if COVID-19-related acute and late-term neurological symptoms exist in the patient group that differs from the general population during the pandemic period. Methods: Two hundred fifty patients with a history of COVID-19, whose treatments were completed at least one month before enrollment, were examined together with a control group consisting of 150 individuals that lived in the same socio-cultural environment during the same period. A survey that included questions about possible neurological symptoms that might be related to the COVID-19 infection was completed in both groups. Results: The patient and control groups were mostly similar regarding the neurological symptoms in the pre-pandemic period. The control group did not report any new symptoms except ageusia during the pandemic period. Whereas a number of neurological symptoms such as headache, ageusia and anosmia, difficulty in thinking and planning, forgetfulness, clumsiness of one or both hands, dizziness, unsteadiness, numbness in both hands and feet, and neuropathic pain occurred during the infection. Neurological symptoms, except headache and unsteadiness, prolonged to the late-term with a decreased prevalence. Conclusion: The emergence of new neurological symptoms during the pandemic in those with COVID-19 disease, unlike the control group, suggested that these symptoms are related to the infection itself.

Objectives: to investigate the effect of the novel coronavirus disease 2019 (COVID-19) pandemic on the clinical practice of ophthalmologists in our country. Materials and methods: a questionnaire consisting of 22 questions was delivered to 250 ophthalmologists via e-mail and a smartphone messaging application. A total of 113 ophthalmologists completed the survey. The questions included the participants’ demographic data (age, years in practice, institution, and city), changes in their working conditions and institutional preventive measures implemented during the pandemic, their personal COVID-19 experiences, the prevalence of telemedicine applications, and their attitudes toward these practices. Results: nearly half (47.8%) of the 113 ophthalmologists were 36 to 45 years old. In terms of years in practice, the largest proportion of respondents (28.3%) had 6-10 years of experience. Most of the participants worked in private/foundation universities (37.2%), while 22.1% worked in education and research clinics. Participants working at public universities most often reported that they or a close contact had to work in COVID wards (89.5%). Triage was performed in 51.5% of ophthalmology outpatient clinics, with 88.0% of these participants reporting that patients with fever, cough, or dyspnea were directed to the pandemic clinic without ophthalmological examination. All participants working in public hospitals, education and research clinics, and public university hospitals had postponed elective surgeries, whereas 12.5% of those working in private practice and 20.5% of those working in private/foundation universities reported that they continued elective surgeries. While 80.8% of the participants did not conduct online interviews or examinations, 40.4% stated that they considered telemedicine applications beneficial. Seventy-seven percent of participants expressed concern about a decrease in their income during the pandemic, with this being especially common among participants working in private practice (87.5%) and private/foundation university hospitals (85.7%). Conclusion: ophthalmologists across our country have been affected by this pandemic at a level that will change their clinical approach. We think that ophthalmologists impacted by the difficulty of providing personal protective equipment and economic concerns should be supported more during the pandemic., NA
