Development of public stigma scales on alcohol use disorder and substance use disorder.

Different attitudes toward alcohol use disorder (AUD) and substance use disorders (SUD) require different evaluation. We aimed to develop and validate two measurement tools that evaluate the public stigma in terms of the stigma model: Public Stigma toward Alcohol Use Disorder Scale (PS-AUDS) and Public Stigma toward Substance Use Disorder Scale (PS-SUDS). The study was conducted with 503 individuals from Turkey. The 20 item- PS-AUDS explained 67.6% of the total variance. The 23 item -PS-SUDS explained 68.7% of the total variance. Cronbach alpha values of the scales were between .93 and .96. Results showed that the scales are valid and reliable.

Outcomes of COVID-19 contact tracing in hospital healthcare workers: A retrospective cohort study.

OBJECTIVE: To determine risk-group-specific rate of becoming COVID-19-positive among healthcare workers having had contact with COVID-19 cases. METHODS: The retrospective cohort study was conducted at the Ege University Hospital, Bornova, Turkey, and comprised all healthcare workers who had come into contact with COVID-19 cases between March 11 and May 31, 2020. The contacts were classified as low-risk, medium-risk and high-risk using the guidelines of the Turkish Ministry of Health. The outcome measures were the incidence of infection among contacts and the incubation period and serial interval among the new cases. Data was analysed using SPSS 23. RESULTS: Of the 845 cases, 312(37%) had high risk, 263(31%) medium and 270(32%) low. Overall, there were 490(58%) females, 355(41%) males, 565(67%) aged <40 years, and 277(33%) aged >40 years. Of the total, 27(3.20%) healthcare workers tested COVID-19-positive and distribution among the risk-based groups was significant (p=0.037). There was a significantly increased risk of incidence among repeated contacts, no mask use, and the source being a colleague (p<0.05). CONCLUSIONS: The detection of high-risk contacts was found to be important for controlling COVID-19 infection in a hospital setting.

Efficacy and safety of ruxolitinib in patients with myelofibrosis: a retrospective and multicenter experience in Turkey

Background/aim: The aim of this study is to assess the efficacy and safety of ruxolitinib in patients with myelofibrosis. Materials and methods: From 15 centers, 176 patients (53.4% male, 46.6% female) were retrospectively evaluated. Results: The median age at ruxolitinib initiation was 62 (28­87) and 100 (56.8%) of all were diagnosed as PMF. Constitutional symptoms were observed in 84.7%. The median initiation dose of ruxolitinib was 30 mg (10­40). Dose change was made in 69 (39.2%) patients. Forty seven (35.6%) and 20 (15.2%) of 132 patients had hematological and nonhematological adverse events, respectively. The mean spleen sizes before and after ruxolitinib treatment were 219.67 ± 46.79 mm versus 199.49 ± 40.95 mm, respectively (p < 0.001). There was no correlation between baseline features and subsequent spleen response. Overall survival at 1-year was 89.5% and the median follow up was 10 (1­55) months. We could not show any relationship between survival and reduction in spleen size (p = 0.73). Conclusion: We found ruxolitinib to be safe, well tolerated, and effective in real-life clinical practice in Turkey. Ruxolitinib dose titration can provide better responses in terms of not only clinical benefit but also for long term of ruxolitinib treatment.

WhatsApp embedded in routine service delivery for smoking cessation: effects on abstinence rates in a randomized controlled study.

BACKGROUND: The demand for smoking cessation services has risen in Turkey, as smokers planning to quit reached 35% in 2012. Communication technologies are used globally to support quitters, yet their integration to health services is rare. This study aims to evaluate the effect of support messages through WhatsApp application added to the usual care of a university hospital cessation unit, as compared to usual care alone, on abstinence rates at first month. METHODS: A randomized controlled intervention study was conducted with 132 patients applying to Ege University Hospital's Department of Public Health Smoking Cessation Clinic, between March and July 2017. Intervention content was prepared and 60 WhatsApp messages about having a plan of action and preventing relapse were developed through expert panels. These messages lasted for 3 months and follow-ups continued for 6 months. The primary outcome was abstinence rate at 1st month post target quit day. As secondary outcomes; the continuous abstinence rates at 3rd and 6th months, number of follow-ups, change in weight and continuity of medication were evaluated. Intention-to-treat analysis was used. RESULTS: Abstinence rate at 1st month was 65.9% in the intervention group and 40.9% in the control group (p = 0.007); 50.0 and 30.7% at 3rd month and 40.9 and 22.7% at 6th month, consecutively (both p < 0.05). Being in the intervention group increased abstinence rate by 3.50 (OR, 95% CI = 1.30-9.44) times in the 1st month. When controlled for all other factors in the multivariate logistic regression, the intervention was the only variable significantly associated with abstinence. For secondary outcomes, the intervention increased abstinence rate by 2.50 (OR, 95% CI = 1.08-6.40) times in the 3rd and 2.31 (OR, 95% CI = 1.03-5.16) times in the 6th month. In the intervention group, the number of follow-ups and face-to-face follow-ups were higher at 1st and 3rd months and continuity of medication was longer at 3rd month. CONCLUSIONS: WhatsApp support embedded in cessation service delivery increases the abstinence rate and has favorable effects on follow-up. TRIAL REGISTRATION: This trial is retrospectively registered online at ClinicalTrials.gov with the identifier NCT03714971 .

Efficacy and safety of lenalidomide and dexamethasone in patients with relapsed/ refractory multiple myeloma: a real-life experience

Background/aim: In Turkey, lenalidomide plus dexamethasone (RD) has been used to treat relapsed/refractory multiple myeloma (RRMM) since 2010. This retrospective, single-center study evaluated the efficacy and tolerability of RD in patients with RRMM between October 2010 and June 2016. Materials and methods: Patients' records were reviewed, and overall (OS) and progression-free survival (PFS) were assessed. Results: One hundred and twenty patients (71 males; 59.2%) were included in the study. The median number of prior lines of treatment was one (1­4); 72 patients (60.0%) received RD as second-line therapy and 51 patients (42.5%) had previously undergone autologous stem cell transplantation (ASCT). The overall response rate was 72.5%, with 19% of these patients achieving a complete response. The median length of follow-up and duration of response to RD was 14 months and 19 months, respectively. Median OS and PFS were 32 and 21 months, respectively. Prior ASCT, an overall response, and treatment with RD for >12 cycles were identified as independent prognostic factors for OS and PFS. Adverse events (AEs) occurred in 69 (57.5%) and 14 patients (11.7%) discontinued treatment due to AEs. Conclusion: We found RD to be safe, well tolerated, and effective in RRMM in everyday clinical practice in Turkey.

Mobile phone use, school electromagnetic field levels and related symptoms: a cross-sectional survey among 2150 high school students in Izmir.

BACKGROUND: Health outcomes of electromagnetic fields (EMF) from mobile phones and their base stations are of concern. Conducting multidisciplinary research, targeting children and exploring dose-response are recommended. Our objectives were to describe the mobile phone usage characteristics of high school students and to explore the association between mobile phone usage characteristics, high school EMF levels and self-reported symptoms. METHODS: This cross-sectional study's data were collected by a survey questionnaire and by measuring school EMF levels between November 2009 and April 2011. A sample size of 2530 was calculated from a total of 20,493 students in 26 high schools and 2150 (85.0%) were included in the analysis. The frequencies of 23 symptoms were questioned and analysed according to 16 different aspects of mobile phone use and school EMF levels, exploring also dose-response. School EMF levels were measured with Aaronia Spectran HF-4060 device. Chi square and trend tests were used for univariate and logistic regression was used for multivariate analyses. RESULTS: Among participants, 2021 (94.0%) were using mobile phones and 129 (6.0%) were not. Among users, 49.4% were speaking <10 min and 52.2% were sending/receiving 75 or more messages per day. Headache, fatigue and sleep disturbances were observed respectively 1.90 (95% CI 1.30-2.77), 1.78 (1.21-2.63) and 1.53 (1.05-2.21) times more among mobile phone users. Dose-response relationships were observed especially for the number of calls per day, total duration of calls per day, total number of text messages per day, position and status of mobile phone at night and making calls while charging as exposures and headache, concentration difficulties, fatigue and sleep disturbances as general symptoms and warming of the ear and flushing as local symptoms. CONCLUSIONS: We found an association between mobile phone use and especially headache, concentration difficulties, fatigue, sleep disturbances and warming of the ear showing also dose-response. We have found limited associations between vicinity to base stations and some general symptoms; however, we did not find any association with school EMF levels. Decreasing the numbers of calls and messages, decreasing the duration of calls, using earphones, keeping the phone away from the head and body and similar precautions might decrease the frequencies or prevalence of the symptoms.

[Evaluation of QuantiFERON®-TB Gold in Tube Test and Tuberculin Skin Test in the diagnosis of Mycobacterium tuberculosis infection]. / Mycobacterium tuberculosis enfeksiyonu tanisinda QuantiFERON®-TB Gold in Tube Testi ve Tüberkülin Deri Testinin degerlendirilmesi.

The aims of this study were to evaluate the sensitivity of QuantiFERON®-TB Gold in Tube (QFT) test and its agreement with the tuberculin skin test (TST), to investigate possible factors associated with indeterminate QFT test results and to explore the relationship between latent tuberculosis infection (LTBE) prevalence and the rate of tuberculosis (TB) cases in our region. 1455 cases with QFT test performed in Ege University Faculty of Medicine Hospital between 2013 and 2015 were included in the study and simultaneously TST results of 268 of 1455 cases were reached. TST results were evaluated according to both ≥ 10 mm and ≥ 15 mm cut-off values. The QFT results of the cases were compared according to their gender, age groups and clinical characteristics with chi-square test. Stratified analyses were also conducted according to age groups. Multivariate logistic regression was used to analyse factors associated with QFT positivity and indeterminate QFT results. Cohen's kappa was used to test the agreement between QFT and TDT, overall and stratified according to age groups. Among 1455 cases, 396 (27.2%) were QFT positive and 120 (8.2%) had an indeterminate QFT result. When the indeterminate results were excluded, QFT positivity was found as 29.7%. The highest indeterminate results were determined among 0-4 year-old and ≥ 65 year-old groups as 17.6% and 12.1%, respectively and lowest among the 55-64 age group as 4%. The comparison of the cases without any cellular immunity defect and the patients with hematologic malignancies or immune deficiency and patients under immunosuppressive treatment had two and 2.44 times more indeterminate QFT results, respectively. Among 268 cases with TST results reached, QFT positivity was 30.6%; 38.1% for TST ≥ 10 mm and 25.7% for TST ≥ 15. After the exclusion of indeterminate results, the agreement between QFT and TST ≥ 10 mm was 71.3% for positive cases and 75.5% for negative cases. The highest agreement between QFT and TST ≥ 10 mm was in the age group 35-64 and lowest in the age group ≥ 65. Among 43 culture-positive cases, 32 had QFT positive, six negative and five indeterminate results. When indeterminate results were excluded, the sensitivity of thetest was 84.2% (32/38) among culture-positive active TB cases. TST results were available for 17 of the culture-positive cases, among them QFT sensitivity was 76.5% (13/17), TST sensitivity 70.6% (12/17) and the sensitivity of both tests was 88.2% (15/17). The ratio of QFT positivity has increased as the age increased. Interestingly, QFT positivity was higher among females than males in the 15-34 age group and higher among males in the 35-64 age group. The rates of QFT positivity were lower among immunocompromised patients. When QFT and TST positivities were compared with the rate of TB cases among age groups, QFT positivity was observed as parallel to the rate of TB cases. In conclusion, although the sensitivity of QFT was higher than TST, it was found that it could not be considered as a gold standard in LTBE diagnosis. As active TB cases originate from the LTBE pool, QFT test results might be considered a better indicator of active TB development risk.

Adjuvant chemotherapy may contribute to an increased risk for metabolic syndrome in patients with breast cancer.

PURPOSE: Cytotoxic treatment may cause weight gain and important alterations in the metabolic status of breast cancer (BC) patients. The aim of this study was to investigate the changes in metabolic and anthropometric parameters of patients with BC who received adjuvant chemotherapy. METHODS: All consecutive women treated with adjuvant TAC (docetaxel 75 mg/m(2), doxorubicine 50 mg/m(2), cyclophosphamide 500 mg/m(2)) chemotherapy for node-positive breast carcinoma at our Institution between 2008 and 2010 were included. RESULTS: Among 104 patients, 84 of them were stage II and 20 of them were stage III. When we compared the measurements between 1(st) and 6(th) adjuvant chemotherapy, we observed statistically significant increases in weight and serum triglyceride levels, and decreases in high density lipoprotein, apolipoprotein A-1, transferrin, albumin and prealbumin levels. An elevation of follicle stimulating hormone, luteinizing hormone together with the decrease of estradiol was detected. Waist-to-hip ratio has also increased significantly. In subgroup analyses, we observed dramatic changes in body mass index in pre-menopausal women whereas no significant change was seen in the post-menopausal group. CONCLUSIONS: Adjuvant chemotherapy may contribute to an increased risk for metabolic syndrome in patients with BC and these changes are more profound in pre-menopausal patients.

Plasma thiopurine S-methyltransferase levels and azathioprine-related adverse events in patients with Behçet's disease.

OBJECTIVES: Thiopurine S-methyltransferase (TPMT) is the key enzyme inactivating azathioprine (AZA), an immunosuppressive agent commonly used for treating inflammatory diseases including Behçet's disease (BD), systemic lupus erythematosus (SLE) and systemic vasculitis. Low TPMT levels facilitate occurrence of AZA-related adverse effects. We investigated TPMT levels in patients with BD, compared to healthy controls and patients with SLE or systemic vasculitis. METHODS: This cross-sectional study included 101 BD (77 using AZA), 74 SLE (35 using AZA), and 44 vasculitis (18 using AZA) patients and 101 healthy controls. Plasma TPMT levels were measured using ELISA. Student's t- and Kruskal-Wallis tests were used to compare TPMT levels according to possible risk factors. Receiver operating characteristic (ROC) analysis was used to determine whether a cut-off TPMT level could be found to predict AZA-related adverse effects. RESULTS: Plasma TPMT levels (mean± SD ng/mL) in BD (22.80±13.81) were comparable with healthy controls (22.71±13.49), but significantly lower than in SLE group (29.37±11.39) (p<0.001). TPMT levels in 130 patients receiving AZA were similar to the rest of the group. AZA-related adverse effects were identified in only 8 patients (5 with BD and 3 with SLE). TPMT levels were significantly lower in those 8 patients (14.08±9.49 vs. 25.62±12.68) (p=0.013), besides a cut-off value for predicting adverse effects was determined for the BD group with ROC analysis (area under the curve: 0.813). CONCLUSIONS: This is the first study to evaluate TPMT activity in a Turkish adult population. Although low plasma TPMT level is not the only factor determining AZA toxicity, a TPMT cut-off value may help to predict AZA-related adverse effects in BD.

Comprehensive Immunohistochemical Analysis of Epithelial-Mesenchymal Transition Biomarkers in the Invasive Micropapillary Cancer of the Breast.

Background: Invasive micropapillary carcinoma (IMPC) of the breast is commonly associated with a poor prognosis due to its high incidence of lymphovascular invasion and lymph node metastasis (LNM). Our study is aimed at investigating the prognostic significance of the expressions of E-cadherin (E-cad), N-cadherin (N-cad), CD44s, and ß-catenin (ß-cat). In addition, it is aimed at deciphering the consistency of these markers between the IMPC, the invasive breast carcinoma, no-special type (IBC-NST), and LNM components in the same IMPC cases. Methods: Sixty-two IMPC cases with LNM from 1996 to 2018 were analyzed. Immunohistochemical staining was performed separately on the three regions for each patient. Statistical analyses included Kaplan-Meier, Cox regression, and McNemar's statistical tests. Results: Loss of CD44 expression in IMPC, IBC-NST, and LNM areas was associated with poor prognosis in overall survival (OS) (p = 0.010, p < 0.0005, p = 0.025). Loss of CD44 expression in the IBC-NST, gain of N-cad expression in the IMPC, and loss of ß-cat expression in the LNM areas were indicators of poor prognosis in disease-free survival (DFS) (p = 0.005, p = 0.041, p = 0.009). Conclusion: Our evaluation of this rare subtype, focusing on the expression of key epithelial-mesenchymal transition (EMT) molecules, revealed that it shares characteristics with the IBC-NST component within mixed tumors. Notably, contrary to expectations, a reduction in CD44 expression was found to adversely affect both OS and DFS. By conducting staining procedures simultaneously across three regions within the same patient, a novel approach has provided valuable insights into the mechanisms of EMT.

Hospital-acquired urinary tract infection point prevalence in Turkey: differences in risk factors among patient groups.

BACKGROUND: The aim of this study was to determine the point prevalence of nosocomial urinary tract infections (UTIs) and to investigate risk factors for pathogen type (E. coli vs. others) and extended-spectrum beta-lactamase (ESBL) positivity among nosocomial UTI patients. METHODS: A questionnaire consisting of 44 questions on demographic data and risk factors of UTI cases was sent to 51 tertiary care hospitals. Univariate and multivariate analyses were conducted. RESULTS: The overall prevalence of UTI was 1.82% (483/26534). The prevalence of UTI was higher in intensive care units (ICUs) with 6.77% versus 1.45% outside ICUs. Hospitals of the Ministry of Health (compared to university hospitals), hospitals in less developed provinces and hospitals with bed capacity < 500 had higher UTI prevalence. Patients without a urinary catheter were more likely to have received immunosuppressive therapy, current corticosteroid use, renal transplantation and uterine prolapsus and less likely to have another infection outside the urinary tract, as compared to catheterized patients. Among the 422 culture-positive patients, the most common pathogen was E. coli (45.5%). The risk factors increasing the likelihood of E. coli in urine culture were being female, history of urinary tract operation, no use of antibiotics in the preceding three months and infection outside the urinary tract. There were 247 patients with E. coli or Klebsiella spp. positive in culture. Among these, 61% (n=151) were ESBL- positive. Among patients having E. coli/Klebsiella positive in culture, antibiotic use in the preceding three months and history of urinary tract operation were the independent risk factors significantly increasing the risk of ESBL. CONCLUSIONS: The reasons underlying the high prevalence of nosocomial UTIs, and a better understanding of the risk factors might lead to improved control of these infections.

Adolescents' risk perceptions on mobile phones and their base stations, their trust to authorities and incivility in using mobile phones: a cross-sectional survey on 2240 high school students in Izmir, Turkey.

BACKGROUND: Use of mobile phones has rapidly risen among adolescents despite a lack of scientific certainty on their health risks. Risk perception is an important determinant of behavior, and studies on adolescents' risk perceptions of mobile phones or base stations are very scarce. This study aims to evaluate high school students' risk perceptions on mobile phones and base stations, their trust to authorities, their opinions regarding incivility while using mobile phones and to assess associated factors. METHODS: For this cross-sectional study, 2530 students were chosen with stratified cluster sampling among 20,493 high school students studying in Bornova district of Izmir, Turkey, among whom 2240 (88.5%) participated. Risk perceptions and opinions were questioned with a 5-point Likert scale for 24 statements grouped under four dimensions. The mean responses to the four dimensions were categorized as <3.5 (low) and ≥3.5 (high) and the determinants were analyzed with logistic regression. RESULTS: Mean risk perception scores for the mobile phone, base station, trust to authority and incivility dimensions were 3.69 ± 0.89, 4.34 ± 0.78, 3.77 ± 0.93, 3.16 ± 0.93 and the prevalence of high risk perception was 65.1%, 86.7%, 66.2%, 39.7%, respectively. In the mobile phone dimension; students attending industrial technical high school had lower risk perceptions while female students, lower mothers' education groups and students not using mobile phones (OR = 2.82, 95% CI = 1.80-4.40) had higher risk perceptions. In the base station dimension girls had higher risk perceptions (OR = 1.68, 95% CI = 1.20-2.37). Girls and students attending industrial technical high school had significantly lower risk perception however 11-12th grade group perceived the risk higher (OR = 1.45 95% CI = 1.15-1.84) in the trust to authority dimension. For the incivility dimension, female students (OR = 1.44, 95% CI = 1.14-1.82), illiterate/only literate mothers (OR = 1.79, 95% CI = 1.04-2.75) and students not using mobile phones (OR = 2.50, 95% CI = 1.62-3.87) perceived higher risk. CONCLUSIONS: Understanding the effects of these determinants might aid in developing more effective educational interventions to specific subgroups on this topic. As debates on the health consequences of electromagnetic fields continue, it would be cautious to approach this issue with a preventive perspective. Efforts should be made to equalize the varying level of knowledge and to ensure that students are informed accurately.

How do determinants of health relate to children's quality of life? A cross-sectional study in Izmir, Turkey.

AIM: This study aims to determine health-related quality of life (QoL) and the related factors from the perspective of social determinants of health among children. BACKGROUND: Childhood is the most intense period of life, and environmental factors surrounding children, as well as individual lifestyle factors, are related to the child's physical and mental well-being. To our knowledge, there is a lack of studies evaluating the relationship between determinants of health and the QoL of healthy children in general. METHODS: This cross-sectional study was executed in the Bayrakli district of Izmir city. Stratified clustered sampling was used including 24 schools and 3367 7th-grade children, and 1284 students were targeted (50% prevalence, 95% CI, %5 margins of error, 2.25 design effect, and 20% replacement). The response rate was 84.9% (n = 1090). The Turkish KID-KINDL Health-Related Quality of Life Questionnaire for Children was used to assess QoL. Independent variables were examined in four layers using Dahlgren's Determinants of Health Model: basic characteristics, lifestyle factors, family characteristics, and life conditions. RESULTS: The mean QoL score was 71.3 ± 12.6. Our study explained 31.7% of the variance in QoL. Higher QoL scores were associated with better health status, perceived academic achievement, normal/thin body perception, physical activity (PA), and adequate sleep duration. Living with both parents and having fewer siblings positively influenced QoL. Moreover, the presence of structural problems in the household and poorer health perceptions were associated with lower QoL scores (P < 0.05) This study highlighted the multifaceted nature of QoL in Turkish children, revealing the importance of various determinants of health. The results show that in order to improve the general well-being of this population, interventions and policies are required that concentrate on elements including health status, academic accomplishment, body perception, physical activity, family structure, and living situations.

Matrix Metalloproteinase-2 and -3 Levels in Patients with Behçet's Disease and Implication for the Presence of Vascular Aneurysm or Neurologic Involvement.

BACKGROUND: Behçet's disease is a systemic vasculitis affecting both arteries and veins, as well as caus- ing recurrent inflammatory multiorgan disease. Vascular involvement is associated with increased mortality and morbidity. Matrix metalloproteinases are released at sites of inflammation and degrade various components of the extracellular matrix. Increased levels of metalloproteinase-9 and metal- loproteinase-2 have been previously reported in Behçet's disease. METHODS: In this cross-sectional study, metalloproteinase-2 and metalloproteinase-3 serum levels were investigated in 103 patients with Behçet's disease and 69 healthy controls, using Invitrogen immunoassay human metalloproteinase-2 and metalloproteinase-3 ELISA kits. RESULTS: Serum metalloproteinase-2 and metalloproteinase-3 levels were significantly higher in the Behçet's disease group compared to healthy controls. Besides, serum metalloproteinase-3 levels were significantly higher in subgroups of Behçet's disease with aneurysmal vascular involvement and with neurological involvement. However, metalloproteinase-2 and metalloproteinase-3 serum levels did not show a positive correlation with disease activity. CONCLUSION: Metalloproteinase-2 and -3 may contribute to the complex pathogenesis of Behçet's dis- ease. More importantly, the detection of very high serum levels of metalloproteinase-3 may predict the formation of an aneurysm, or possibly the presence of neurological involvement in Behçet's dis- ease and may lead the clinician to make an earlier diagnosis of these complications in young male patients with high risk.

COVID-19 Infection, Vaccination, and Antibody Levels: Investigating Correlations through a Cohort Study.

AIM: The objective of this study was to explore the potential correlation between COVID-19 infection or vaccination and levels of anti-nucleocapsid (anti-N) and anti-spike (anti-S) antibodies. METHODS: Among 6050 healthcare workers at the Ege University Hospital, a cohort study with 162 participants divided into three arms with 54 participants each was conducted. The three groups were selected as follows: those diagnosed with COVID-19 and not vaccinated (group 1), those diagnosed with COVID-19 and subsequently vaccinated with CoronaVac (group 2), and those not diagnosed with COVID-19 but vaccinated with two doses of CoronaVac (group 3). Antibody levels measured at the sixth month of follow-up were defined as the primary outcome. RESULTS: At the sixth month, all serum samples tested positive for anti-S. Anti-S levels were found to be significantly higher in group 2 than in the other groups (p < 0.001). There were no differences in antibody levels between groups 1 and 3 (p = 0.080). Average antibody levels were found to be lower in office workers and males. Anti-N antibodies were found to be positive in 85.1% of subjects at the sixth month. In group 2, anti-N antibodies were detected in all samples at the sixth month. Anti-N antibody levels were not significantly different between groups 1 and 2 (p = 0.165). Groups 1 and 2 had significantly higher antibody levels than group 3 (p < 0.001). CONCLUSIONS: Vaccination or infection provide protection for at least 6 months. Those who have previously been diagnosed with COVID-19 do not need to be vaccinated in the early period before their antibody levels decrease.

Risk factors for occupational hand injuries: relationship between agency and finger.

BACKGROUND: The aim of this study was to define the risk factors for occupational hand injuries and explore the relationship between the machines and the fingers injured, based on the records of a hospital in Turkey specialized in hand and microsurgery. METHODS: Five thousand twenty seven occupational hand injuries treated at a hand and microsurgery hospital between 1992 and 2005 were included in the study. All the injuries were retrospectively recoded according to ICD-10, (ICECI) and ILO recommendations. Logistic regression and chi-square for trend analysis were used to evaluate the risk factors for occupational injuries. RESULTS: The most frequent injuries were traumatic amputation of wrist and hand (53.2%), open wound of wrist and hand (46.3%). Considering all injuries, 60.9% of agricultural machines, 52.7% of metal working machines, 54.7% of transmission machinery, and 42.8% of wood and assimilated machines affected the right hand. Powered wood cutters, presses, planning and milling machines, and machine belts were the most frequent five machines involved in injuries, each having a different finger pattern. The proportion of machinery among all hand injuries was significantly decreasing with time. CONCLUSION: A stricter and more frequent supervision of the use of protective equipment and prohibition of the purchase of machinery not complying with the regulations could contribute to the prevention of hand injuries.

Breastfeeding, nutrition and type 1 diabetes: a case-control study in Izmir, Turkey.

BACKGROUND: The relationship between infant breastfeeding and type 1 diabetes mellitus (DM) is unclear but it has been suggested that there may be a link between many environmental factors, including dietary antigens affecting diabetes epidemiology. The main objective of this study is to investigate nutritional risk factors, especially breastfeeding early in life that may be associated with the development of type 1 DM and to determine the relationship these factors have with the disease. METHODS: This research is a case-control study and was carried out in Ege University Children's Hospital in Izmir, Turkey between 13 January 2020 and 5 March 2020. A total of 246 children aged between 4 and 14 years were included in the study. The case group consisted of patients diagnosed with type 1 DM followed-up by Ege University Children's Hospital's Endocrinology Unit and the control group included non-diabetic children attending the same hospital's General Pediatric Outpatient Clinic. A structured questionnaire was created by the researchers after reviewing the literature related to nutritional and other risk factors for type 1 DM. The questionnaire was administered by interviewing the parents and it was related to the child, mother and family of the child. In this study, breastfeeding duration was defined as the total duration of breastfeeding and exclusive breastfeeding meant that the child received only breast milk from the mother. RESULTS: The mean age at diagnosis was 6.30 ± 4.03 years for cases and 7.48 ± 2.56 years for controls. We found that each monthly increase in exclusive breastfeeding duration provided a 0.83-fold (95% CI 0.72, 0.96) decrease in the risk of type 1 DM. Introduction of cereals in the diet at the sixth month or earlier was associated with a 2.58-fold (95% CI 1.29, 5.16) increased risk. CONCLUSIONS: Determining the contribution of exclusive breastfeeding to the disease is important in establishing preventive policies. A longer duration of exclusive breastfeeding may be an important role in preventing the disease. This free intervention that truly works will be cost-effective. Future studies are needed to clarify the role of both exclusive and non-exclusive breastfeeding on the development of type 1 DM.

Prognostic Value of Receptor Change After Neoadjuvant Chemotherapy in Breast Cancer Patients.

Objective: The aim of this study was to investigate the relationship between hormone receptors (HR) and human epidermal growth factor receptor 2 (HER-2) discordance with prognosis, before and after neoadjuvant chemotherapy (NAC) in breast cancer patients. Materials and Methods: Histopathological data of 142 breast cancer patients attending a single center between 2001 and 2018 and were operated after NAC were evaluated retrospectively. Results: The median (range) age of patients was 58 (32-69) years. In patients who underwent Tru-cut biopsy before NAC, 77 patients were ER+, 30 were ER (-), 73 were PR (+), 33 were PR-, 14 were HER-2 (+), and 94 patients were HER-2 (-). In terms of ER change, five patients were found to have changed status and 85 had no receptor change. The mean overall survival of patients with receptor changes was 31 months against 60 months in patients with no receptor changes, which was not significant (p = 0.351). In sub-group analysis of patients undergoing receptor change, the ER (+) → (-) group had significantly shorter survival (p = 0.003). For PR change, mean survival was 38 months in seven patients with a receptor change and 59 months in 87 patients without a receptor change, which was not significant (p = 0.603). Sub-group analysis of PR status change showed that survival was significantly shorter in the PR (+) → (-) group (p = 0.012). Conclusion: These results suggest there is a need for reassessment of HR and HER-2 status in surgical samples from patients following NAC, and that NAC-induced changes in the HR state may be used as a prognostic factor.

Did the pandemic have an impact on influenza vaccination attitude? A survey among health care workers.

BACKGROUND: Health care workers' (HCWs) influenza vaccination attitude is known to be negative. The H1N1 epidemic had started in mid 2009 and made a peak in October-November in Turkey. A national vaccination campaign began on November 2nd, 2009. Despite the diligent efforts of the Ministry of Health and NGOs, the attitudes of the media and politicians were mostly negative. The aim of this study was to evaluate whether HCWs' vaccination attitudes improved during the pandemic and to assess the related factors. METHODS: This cross-sectional survey was carried out at the largest university hospital of the Aegean Region-Turkey. A self-administered questionnaire with 12 structured questions was applied to 807 HCWs (sample coverage 91.3%) before the onset of the vaccination programme. Their final vaccination status was tracked one week afterwards, using immunization records. Factors influencing vaccination rates were analyzed using ANOVA, t-test, chi-square test and logistic regression. RESULTS: Among 807 participants, 363 (45.3%) were doctors and 293 (36.6%) nurses. A total of 153 (19.0%) had been vaccinated against seasonal influenza in the 2008-2009 season. Regarding H1N1 vaccination, 143 (17.7%) were willing to be vaccinated vs. 357 (44.2%) unwilling. The number of indecisive HCWs was 307 (38.0%) one week prior to vaccination. Only 53 (11.1%) stated that they would vaccinate their children. Possible side effects (78%, n = 519) and lack of comprehensive field evaluation before marketing (77%, n = 508) were the most common reasons underlying unwillingness or hesitation.Among the 749 staff whose vaccination status could be tracked, 228 (30.4%) actually received the H1N1 vaccine. Some of the 'decided' staff members had changed their mind one week later. Only 82 (60%) of those willing, 108 (37%) of those indecisive and 38 (12%) of those unwilling were vaccinated.Indecisive HCWs were significantly younger (p = 0.017). Females, nurses, and HCWs working in surgical departments were more likely to reject vaccination (p < 0.05). Doctors, HCWs working in medical departments, and HCWs previously vaccinated against seasonal influenza were more likely to accept vaccination (p < 0.05). Being younger than 50 and having been vaccinated in the previous season were important predictors of attitude towards pandemic influenza vaccination. CONCLUSIONS: Vaccination rates increased substantially in comparison to the previous influenza season. However, vaccination rates could have been even higher since hesitation to be vaccinated increased dramatically within one week (only 60% of those willing and the minority of those indecisive were finally vaccinated). We speculate that this may be connected with negative media at the time.

Clinicopathologic features of single bone metastasis in breast cancer.

ABSTRACT: The most common site for metastasis in patients with breast cancer is the bone. In this case series, we investigated patients whose surgical and medical treatment for primary breast cancer was conducted at our center and first disease recurrence was limited to only 1 bone.We analyzed 910 breast cancer patients, 863 had no metastasis and 47 cases had a single bone metastasis ≥ 6 months after their first diagnosis. Demographic, epidemiological, histopathological and intrinsic tumor subtype differences between the non-metastatic group and the group with solitary bone metastases and their statistical significance were examined. Among established breast cancer risk factors, we studied twenty-nine variables.Three variables (Type of tumor surgery, TNM Stage III tumors and mixed type (invasive ductalcarsinoma + invasive lobular carcinoma) histology) were significant in multivariate logistic regression analysis. Accordingly, the risk of developing single bone metastasis was approximately 15 times higher in patients who underwent mastectomy and 4.8 and 2.8 times higher in those with TNM Stage III tumors and with mixed type (invasive ductal carcinoma + invasive lobular carcinoma) histology, respectively.In conclusion, the risk of developing single bone metastasis is likely in non-metastatic patients with Stage III tumors and possibly in mixed type tumors. Knowing this risk, especially in patients with mixed type tumors, may be instrumental in taking measures with different adjuvant therapies in future studies. Among these, treatment modalities such as prolonged hormone therapy and addition of bisphosphonates to the adjuvant treatments of stage III and mixed breast cancer patients may be considered.
