Publication Metadata only İstanbul’da Satılan Dondurmaların Mikrobiyolojik Kalite ve Antibiyotik Dirençlerinin Belirlenmesi ve Halk Sağlığı Açısından Değerlendirilmesi(2023-03-15) Güneş Bayır A.; Erdoğan Ö.; Güçlü D.; Özkan B.; GÜNEŞ BAYIR, AYŞE; ERDOĞAN, ÖZCAN; GÜÇLÜ, DUYGUIce cream is a kind of dessert consumed with various flavors. However, considering the nutrients of ice creams, it seems to be a good environment for the propagation of microorganisms. Therefore, it was aimed to determinate the microbiological quality of ice creams sold in the open according to Turkish Food Codex on Microbiological Criteria Regulation in this study. Microbiological quality of ice cream samples was evaluated in terms of public health risks and food unsafety which may occur during the production, storage and sales of ice creams. Seventy-five ice cream samples flavored with plain, fruit, and nuts were collected aseptically from 25 enterprises in Istanbul, Türkiye. The presence or absence and enumeration of Total Mesophilic Aerobic (TMA) bacteria, Enterobacteriaceae, Staphylococcus aureus and Salmonella spp. were investigated using related media. The results were evaluated according to the Turkish Food Codex on Microbiological Criteria Regulation. S. aureus found in some ice cream samples was examined for antibiotic resistance against 7 different antibiotics. About a third of all ice cream samples (32%; n=8) from 25 enterprises were found as ‘safe’ in accordance with the Turkish Food Codex on Microbiological Criteria Regulation in terms of public health. The TMA bacteria was determined %88 (n=22) in plain ice creams, %64 (n=16) in fruit ice creams and %92 (n=23) in nuts ice creams. Enterobacteriaceae were found 40% (n=10) of plain ice creams, 12% (n=3) of fruits and 40% (n=10) of nuts. Multiple antibiotic resistance was determined for S. aureus in only one enterprises\"s nuts flavored ice cream. Salmonella spp. was not found in any of collected ice cream samples. Ice creams sold in the open was seen that the microbiological quality of less than half of the enterprises was not at the desired level. Possibly, the unhygienic conditions of production, transportation and sale are eroding the food safety of this delicious dessert. According to the findings of our study, the high prevalence of microbial contamination in ice cream sold in the open may poses a risk to public health.

Recent studies have revealed that videos on YouTube (TM) are misleading or that medical videos may not contain appropriate information. This study aimed to assess the quality and reliability of videos on nutrition after bariatric surgery. Materials and Methods The keywords -after bariatric surgery diet- and -weight loss surgery postop diet- were used, and the first 100 videos for each keyword on YouTube (TM) were analyzed by considering the source, duration, content, and the number of likes of the video. The popularity of the video was calculated using the video power index (VPI) and view rate. The educational quality of the videos was evaluated using the DISCERN score, the Journal of the American Medical Association (JAMA) score, the Global Quality Score (GQS), the usefulness score, and a novel postoperation nutrition score (PONS). Results One hundred fourteen patients were included in the study. The mean duration and number of views were 12.51 min and 87,558.46, respectively. The DISCERN score, JAMA score, GQS, and usefulness score of the physicians or dietician-based videos were significantly higher than those of the patient-based videos (p < 0.001). Positive correlations were found between the VPI and view ratio, as well as between the duration and number of likes. Additionally, the DISCERN score was significant correlated with the duration and number of likes. Significantly positive correlations were found between the usefulness score and duration, usefulness score and number of likes, and PONS and duration (p < 0.01). Conclusions Informational videos on nutrition after bariatric surgery on YouTube (TM) are of low quality. Although the videos uploaded by physicians and dieticians have higher quality, only a few are available. Additionally, patients prefer to watch low-quality videos.Publication Metadata only Determination of Microbiological Quality of Ice Cream Sold in Istanbul and Their Evaluation in Terms of Public Health(2022-12-01) Güçlü D.; Güneş Bayır A.; Erdoğan Ö.; Özkan B.; GÜÇLÜ, DUYGU; GÜNEŞ BAYIR, AYŞE; ERDOĞAN, ÖZCANPublication Metadata only Tarçının (Cinnamomum sp.) probiyotik yoğurdun mikrobiyolojik, kimyasal ve duyusal özellikleri üzerine etkisinin araştırılması(2019-06-30T00:00:00Z) Bilgin, Mehmet Gültekin; Güçlü, Duygu; Poğda, Sultan; GÜNEŞ BAYIR, AYŞE; BİLGİN, MEHMET GÜLTEKİN; GÜÇLÜ, DUYGUPublication Metadata only Üniversitesi öğrencilerinin kafein tüketiminin değerlendirilmesi(2019-10-12T00:00:00Z) Cin, Pelin; Batar, Nazlı; Güçlü, Duygu; GÜÇLÜ, DUYGUPublication Metadata only Nutritional Assessment of the Departments for Nutrition& Dietetics and Nursing Students at a Private University(2017-10-01T00:00:00Z) Güneş Bayır, Ayşe; Güçlü, Duygu; GÜNEŞ BAYIR, AYŞE; GÜÇLÜ, DUYGUPublication Metadata only Bariatric surgery and vegan: A first case report(2021-08-01T00:00:00Z) Batar, Nazlı; Yıldız, Nida; Kermen, Seda; Güçlü, Duygu; Özçalkap, Rümeysa; GÜÇLÜ, DUYGUPublication Metadata only Nutritional Assessment of Students in Different Grades from the Department of Nutrition& Dietetics(2017-09-30T00:00:00Z) Güneş Bayır, Ayşe; Güçlü, Duygu; GÜÇLÜ, DUYGUPublication Metadata only Effects of Brown Adipose Tissue on Human Metabolism and Weight Loss(2022-05-01T00:00:00Z) Güçlü, Duygu; Demirkıran, Tuğba; GÜÇLÜ, DUYGU
