Background/AimsBecause of the inflammatory nature of coronary artery disease (CAD), both platelets and white blood cells have been investigated for years. The aim of this study was to investigate the relationships between some prominently hematologic blood count parameters (mean platelet volume [MPV], neutrophil to lymphocyte ratio [NLR]) and the severity of CAD by using Gensini scores.MethodsA total of 194 patients, who had undergone coronary angiography, enrolled in this study. The control group consisted of 42 patients who had normal coronary arteries. Remaining CAD patients were divided into two groups according to their Gensini scores.ResultsNLR and MPV were higher in the severe atherosclerosis group compared with the mild atherosclerosis group (p = 0.007, p = 0.005, respectively). The Gensini score showed significant correlations with NLR (r = 0.20, p = 0.011), MPV (r = 0.23, p = 0.004) and high density lipoprotein cholesterol (r = –0.161, p = 0.047). Using a cut-off level of 2.54, NLR predicted severe atherosclerosis with a sensitivity of 74% and specificity of 53% (area under curve [AUC], 0.627; 95% confidence interval [CI], 0.545 to 0.704; p = 0.004). MPV values above 10.4 predicted severe atherosclerosis with a sensitivity of 39% and specificity of 90% (AUC, 0.631; 95% CI, 0.549 to 0.708; p = 0.003). In the multiple logistic regression analysis, high levels of NLR (odds ratio [OR], 1.450; 95% CI, 1.080 to 1.945; p = 0.013) and MPV (OR, 1.622; 95% CI, 1.147 to 2.295; p = 0.006) were found to be independent predictors of severe atherosclerosis.ConclusionsOur study suggests that both NLR and MPV are predictors of severe atherosclerosis and may be used for the prediction and identification of cardiac risks in CAD patients.

Hashimoto's thyroiditis (HT) is the most common endocrine disorder leading to hypothyroidism. HT is characterized by the presence of elevated circulating antibodies, especially anti-thyroid peroxidase (anti-TPO) and anti-thyroglobulin (anti-Tg). In our study, we aimed to reveal the effects of autoimmunity on health-related quality of life of euthyroid HT patients. Patients who were admitted to the Adnan Menderes University Outpatient Clinic were enrolled. The medical records of the patients were surveyed and their demographical data were collected. By using communication data, the patients were invited to our clinic, to inform them about our study and to fill out the health-related quality of life questionnaire. A total of 84 euthyroid HT patients older than 18 years who completed the short form-36 questionnaire, were enrolled. As all patients were euthyroid, there was a significant negative correlation between each domain score and the antibody levels, individually. Patients who had higher anti-TPO and anti-Tg levels had significantly lower quality of life domain scores (p < 0.001). There was statistically no significant correlation between the antibody levels and thyroid function tests (p > 0.05). Additionally, all dimension scores were significantly higher both in the anti-Tg and anti-TPO negative groups, indicating a better quality of life than that in the antibody positive groups. Our study revealed that higher thyroid antibody levels were negatively correlated with life quality scores. Thus, patients who had higher anti-TPO and anti-Tg levels had significantly lower quality of life domain scores. We believe that apart from hypothyroidism, a high antibody level was one of the contributing factors for the development of HT-associated symptoms, leading to a lower quality of life. Other probable contributing factors such as selenium deficiency, thyroid hormone fluctuation, and disease awareness should keep in mind.

Iron deficiency anemia (IDA) is a frequent health problem. Gut parasites such as N. americanus and A. duodenale are known to cause blood loss, but the role of Blastocystis hominis is uncertain. In this study, 212 patients (193 female, 19 male, mean age 41 SD 15 yrs) with IDA were enrolled and 90 persons without IDA (78 female, 12 male, mean age 45 SD 17 yrs). Microscopic examination of stools for B. hominis using the native lugol method was done three times on each subject. If any specimen contained five or more cysts per x400 field, the person was considered positive. B. hominis was found in 48 out of 212 subjects with IDA (22.6%) and in five of 90 (5.6%) subjects without IDA. This difference is highly statistically significant (P < 0.001). Few subjects had other gut parasites and there was no statistical difference in the ir frequencies between IDA and non-IDA subjects. Blastocystis hominis may play a role in the development of IDA either on its own or in conjunction with some other agent.

Objectives:To investigate whether electrolyte levels measured by using blood gas analyzers (ABG) and auto-analyzers (AA) are equivalent and can be used interchangeably.Methods:This observational prospective study was conducted in 100 patients admitted to the Intensive Care Unit, Adnan Menderes University School of Medicine, Aydin, Turkey, between March and August 2014. Samples for both AA and ABG analyzers were collected simultaneously from invasive arterial catheters of patients. The electrolyte levels were measured by using 2 methods.Results:The mean sodium level measured by ABG was 136.1±6.3 mmol/L and 137.8±5.4 mmol/L for AA (p=0.001). The Pearson’s correlation coefficient was 0.561 (p<0.001). The Bland-Altman 95% limits of agreement were -9.4 to 12.6 mmol/L. The mean potassium levels measured by ABG was 3.4±0.7 mmol/L and AA was 3.8±0.7 mmol/L (p=0.001). The Bland-Altman comparison limits were -0.58 to 1.24 and the associated Pearson’s correlation coefficient was 0.812 (p<0.001).Conclusion:The results of the 2 analyzing methods, in terms of sodium, were not equivalent and could not be used interchangeably. However, according to the statistical analyses results, by including, but not blindly trusting these findings, urgent and vital decisions could be made by the potassium levels obtained from the BGA, but a simultaneous follow-up sample had to be sent to the central laboratory for confirmation.

Background Calculating the disease burden due to injury is complex, as it requires many methodological choices. Until now, an overview of the methodological design choices that have been made in burden of disease (BoD) studies in injury populations is not available. The aim of this systematic literature review was to identify existing injury BoD studies undertaken across Europe and to comprehensively review the methodological design choices and assumption parameters that have been made to calculate years of life lost (YLL) and years lived with disability (YLD) in these studies. Methods We searched EMBASE, MEDLINE, Cochrane Central, Google Scholar, and Web of Science, and the grey literature supplemented by handsearching, for BoD studies. We included injury BoD studies that quantified the BoD expressed in YLL, YLD, and disability-adjusted life years (DALY) in countries within the European Region between early-1990 and mid-2021. Results We retrieved 2,914 results of which 48 performed an injury-specific BoD assessment. Single-country independent and Global Burden of Disease (GBD)-linked injury BoD studies were performed in 11 European countries. Approximately 79% of injury BoD studies reported the BoD by external cause-of-injury. Most independent studies used the incidence-based approach to calculate YLDs. About half of the injury disease burden studies applied disability weights (DWs) developed by the GBD study. Almost all independent injury studies have determined YLL using national life tables. Conclusions Considerable methodological variation across independent injury BoD assessments was observed; differences were mainly apparent in the design choices and assumption parameters towards injury YLD calculations, implementation of DWs, and the choice of life table for YLL calculations. Development and use of guidelines for performing and reporting of injury BoD studies is crucial to enhance transparency and comparability of injury BoD estimates across Europe and beyond.
