Publication Childhood leukemia and electromagnetic fields(Galenos Yayıncılık, 2009-12-01) Türkkan, Alpaslan; TÜRKKAN, ALPASLAN; Tıp Fakültesi; Halk Sağlığı Ana Bilim Dalı; AAH-2931-2021In this review, the relationship between very low frequency electromagnetic fields, originating from high voltage powerlines, and childhood leukemia was evaluated. Electromagnetic fields have biological effects. Whole populations are effected by different levels of electromagnetic fields but children are more sensible. In urban areas high voltage powerlines are the main sources of electromagnetic fields. The relation of electromagnetic fields due to high voltage powerlines and leukemia with consideration of dose-response and distance is investigated in several studies. There are different opinions on the effects of electromagnetic fields on general health. The relation between electromagnetic fields and childhood leukemia must be considered separately. Although there is no limit value, it is generally accepted that exposure to 0.4 mu T and over doubles the risk of leukemia in children 15 years and younger.Publication Nine-month course of SARS-CoV-2 antibodies in individuals with COVID-19 infection(Springer London Ltd, 2022-01-20) Türkkan, Alpaslan; Sağlık, İmran; Turan, Cansu; Şahin, Ahmet; Akalın, Halis; Ener, Beyza; Kara, Ateş; Çelebi, Solmaz; Şahin, Emre; Hacımustafaoğlu, Mustafa; TÜRKKAN, ALPASLAN; SAĞLIK, İMRAN; TURAN, CANSU; AKALIN, EMİN HALİS; ENER, BEYZA; ÇELEBİ, SOLMAZ; ŞAHİN, EMRE; HACIMUSTAFAOĞLU, MUSTAFA KEMAL; Tıp Fakültesi; Halk Sağlığı Ana Bilim Dalı; 0000-0003-0864-4989; 0000-0003-3146-6391; 0000-0002-4415-076X; 0000-0001-7530-1279; 0000-0002-1654-3232; 0000-0003-4646-660X; GFL-2282-2022; GCM-3391-2022; IVB-4013-2023; AAU-8952-2020; CNK-0895-2022; ENK-4130-2022; JFP-8395-2023; CTG-5805-2022Background The continual course of the pandemic points to the importance of studies on the rate and durability of protective immunity after infection or vaccination. Aims In this study, we aimed to monitor anti-nucleocapsid (N) and anti-spike (S) antibodies against SARS-CoV-2 nearly 9 months duration after infection. Methods Anti-nucleocapsid (N) (at 11-15-20-29-38 weeks) and anti-spike antibodies (at 11 and 38 weeks) against SARS-CoV-2 were monitored during 38 weeks after the initial symptoms of COVID-19. Results Of 37 cases between 18 and 57 years old, 54% were women. The findings showed that anti-N antibodies decreased significantly after the 15th week (between 15 and 20 weeks, p = 0.016; 20-29 weeks, p = 0.0009; and 29-38 weeks, p = 0.049). At the 38th week, mean antibody levels decreased 35% compared to the 11th week, and 8% of the cases turned negative results. Anti-N antibody average level was 56.48 on the 11th week (the cut-off index threshold >= 1). It was estimated statistically that it would decrease to an average of 20.48 in weeks 53-62. In females, average antibody levels of all measurements were lower than males (p > 0.05). Anti-S antibody levels 14% increased at 38th week compared to 11th week (quantitative positivity threshold >= 0.8 U/ml), and no cases were negative at 38th week. Conclusions Patients had >= 90% positivity after at least 9 months of symptoms, both anti-N and anti-S antibodies. In all samples, both anti-N and anti-S antibody levels were lower in females. The findings suggest that the quantitative values of anti-S antibodies remained high for at least 9 months and could provide protection.Publication All-cause excess mortality in 2020: The example of Bursa city in Turkey(Tasarım Bilişim, 2021-12-01) Pala, KayIhan; Yürekli, Neşe; Çağaç, Nil Kader; Türkkan, Alpaslan; PALA, KAYIHAN; YÜREKLİ, NEŞE; ÇAĞAÇ, NİL KADER; TÜRKKAN, ALPASLAN; Tıp Fakültesi; Halk Sağlığı Ana Bilim Dalı; 0000-0002-0983-4904; 0000-0002-9707-0675; 0000-0001-5267-5008; 0000-0002-6723-1829; GEW-1272-2022; JNJ-8483-2023; JNF-1087-2023; JNM-0660-2023Background: This study aimed to estimate excess all-cause mortality rates in Bursa Province in 2020. Methods: In this study, a retrospective descriptive analysis of the mortality rates in Bursa, Turkey's fourth biggest city, between 2015-2020 was conducted. The data were taken from Bursa Metropolitan Municipality death records. Daily mortality data were classified as age, gender, the date and cause of death (communicable or non-communicable disease). An Excel mortality calculator was used to analyze the data and calculate the excess mortality. Excess mortality was calculated with a 5-year death average. The excess mortality-expected death ratio (P-score) was calculated as a percentage difference between the average number of deaths in 2015-2019 and the number of deaths in the same period (week or month) of 2020. The Chi-square test was used for statistical analysis. Results: In 2020 in Bursa, crude excess mortality was calculated as 5390 (95% CI: 4525-6256) compared to the previous five years' average, and the P-score was 35%. Excess mortality decreased in the 0-14 age group in both genders and increased mainly in the 65+ age group. In 2020, 85.3% of the excess mortality was due to communicable diseases, and 4596 (95% CI: 4562-4631) people reported to die due to communicable diseases. Thus, deaths because of communicable diseases increased approximately 76 times in 2020 compared to the previous five years' average. Conclusion: Compared to the previous five years' average, the annual number of deaths in Bursa increased by approximately one-third in 2020, and most of the excess deaths were due to communicable diseases. For the use of revealing the actual burden of the COVID-19 pandemic on all-cause mortality, it is crucial to assess the extreme all-cause mortality.Publication The effect of house visits on hypertension control in the elderly: A study from Bursa, Turkey(Güneş Kitabevi, 2015-01-13) Pala, Kayıhan; Gerçek, Harika; Türkkan, Alpaslan; PALA, KAYIHAN; Gerçek, Harika; TÜRKKAN, ALPASLAN; Tıp Fakültesi; Halk Sağlığı Ana Bilim Dalı; 0000-0002-6723-1829; 0000-0002-0983-4904; AAH-2931-2021; F-7816-2013; EXQ-7817-2022Introduction: The aim of this study was to evaluate the effect of house visits on hypertension control in the elderly.Materials and Method: In Bursa, the Nilufer Public Health Training and Research Area conducts a follow-up program for the elderly. Nurses and midwives visit people over 65 years of age every six months, which is a new practice in Turkey. During these visits, they measure blood pressure and ask questions about their patients' health conditions. If the patients' blood pressure is high then they are referred to a physician. In that case, the patients are also re-visited by the nurse or midwife the following month to check whether they consulted a physician and to observe the current condition of the patients' health. Follow-up cards of elderly patients were analysed. People who were visited regularly every six months and who had four blood pressure measurements (1063 women and 713 men) were included.Results: The prevalence of women with normal blood pressure (normal, prehypertension or controlled) was 34.5% at the first visit and it increased to 46.4% at the fourth visit (p < 0.05). For men, the corresponding percentages were 41.4% and 54.4%, respectively (p < 0.05).Conclusion: In this study, there was a positive effect of house visits by public health nurses and midwives on hypertension management in the elderly.
