Discrepancy between German S3 Guideline Recommendations and Daily Urologic Practice in the Management of Nonmuscle Invasive Bladder Cancer: Results of a Binational Survey.

INTRODUCTION: Guideline recommendations are meant to help minimize morbidity and to improve the care of nonmuscle invasive bladder cancer (NMIBC) patients but studies have suggested an underuse of guideline-recommended care. The aim of this study was to evaluate the level of adherence of German and Austrian urologists to German guideline recommendations. METHODS: A survey of 27 items evaluating diagnostic and therapeutic recommendations (15 cases of strong consensus and 6 cases of consensus) for NMIBC was administered among 14 urologic training courses. Survey construction and realization followed the checklist for reporting results of internet e-surveys and was approved by an internal review board. RESULTS: Between January 2018 and June 2019, a total of 307 urologists responded to the questionnaire, with a mean response rate of 71%. The data showed a weak role of urine cytology (54%) for initial diagnostics although it is strongly recommended by the guideline. The most frequently used supporting diagnostic tool during transurethral resection of the bladder was hexaminolevulinate (95%). Contrary to the guideline recommendation, 38% of the participants performed a second resection in the case of pTa low-grade NMIBC. Correct monitoring of Bacille Calmette-Guérin (BCG) response with cystoscopy and cytology was performed by only 34% of the urologists. CONCLUSIONS: We found a discrepancy between certain guideline recommendations and daily routine practice concerning the use of urine cytology for initial diagnostics, instillation therapy with a low monitoring rate of BCG response, and follow-up care with unnecessary second resection after pTa low-grade NMIBC in particular. Our survey showed a moderate overall adherence rate of 73%. These results demonstrate the need for sharpening awareness of German guideline recommendations by promoting more intense education of urologists to optimize NMIBC care thus decreasing morbidity and mortality rates.

Effect of Chemokine Gene Variants on Covid-19 Disease Severity.

Patients immune phenotype/genotype data may be useful to understand the molecular mechanisms involved in SARS-CoV-2 infection and can contribute to the identify the different levels of disease severity. The roles of chemokines have been reported in the coronavirus-related diseases SARS and MERS and they may likewise play a critical role in the development of the symptoms of COVID-19 disease. We analyzed the association of the MCP-1-A2518 G, SDF-1-3'A, CCR5-delta32, CCR5-A55029 G, CXCR4-C138T and CCR2-V64I gene polymorphisms with COVID-19 severity to further unveil the immunological pathways leading to disease severity and death. Polymerase chain reaction(PCR)/Sanger sequencing analysis was performed for detection of the variations in 60 asymptomatic and 119 severe COVID-19 patients. In our study, we found that the frequencies of MCP-1 of GA genotype and G allele carriers were significantly higher in severe COVID-19 patients than the asymptomatic COVID-19 patients (p < .0001 and p: .005, respectively). However, no significant association was found for any of the other polymorphisms with the severity of COVID-19. Our findings suggest that there is a positive association between MCP-1-A2518 G gene variants with the severity of COVID-19. However, larger studies in different population which will focus on gene expression levels will help us to understand the capability of the mechanism role.

Correlation between Academic Citations in Emergency Medicine Journals and Twitter mentions.

INTRODUCTION: Twitter may be used in disseminating scientific information that can be measured via citations by traditional systems. We aimed to investigate the relationship between Twitter mentions, traditional citations including Google Scholar and Scopus, and the metric value of Altmetric for articles published in emergency medicine journals. METHODS: Articles published in emergency medicine journals between January 2018 and June 2018 were retrospectively analyzed in February 2021. Journals included with an impact factor of >1 and indexed in Q1. Metric data about citations in Google Scholar and Scopus, the metric value of the Altmetric system, and Twitter mentions were obtained. RESULTS: There were 502 articles published in different seven emergency medicine journals. Fifty-four articles (10.8%) were never cited in Google Scholar or Scopus. There were 79 articles (15.7%) without Twitter mention. Twitter mentions as a tweet or no tweet impacted the number of articles with citation (p > 0.05). The number of citations per article was significantly higher in articles with Twitter mentions (p = 0.002 for Google Scholar citations, p = 0.005 for Scopus citations). Altmetric cited articles were significantly higher for articles with Twitter mentions (p < 0.001). There were significant positive correlations between the number of Twitter mentions and citations in Scopus (r = 0.30, p < 0.001), in both Google Scholar and Scopus (r = 0.19, p < 0.001), and in Altmetrics (r = 0.852, p < 0.001). CONCLUSION: There were positive correlations between numbers of Twitter mentions, traditional citations, including Google Scholar and Scopus, and metric values of the Altmetric system. This finding supports that increased social media citations are associated with increased dissemination and disclosure of publications.

Utility of non-invasive synchronized intermittent mandatory ventilation in acute cardiogenic pulmonary edema.

BACKGROUNDS: Acute cardiogenic pulmonary edema (ACPE), one of the outcomes of acute heart failure (AHF), is a common reason in a critical condition with respiratory distress. Non-invasive synchronized intermittent mandatory ventilation(nSIMV) mode, which includes inspiratory pressure in addition to positive end expiratory pressure with/without pressure support provided in the non-invasive continuous positive airway pressure plus/pressure support(nCPAP/PS) mode can be effective in hypercarbia and the associated changes in consciousness. This study aimed to demonstrate the efficacy of nSIMV in ACPE. METHODS: Patients who presented with clinical acute respiratory failure and were admitted to the critical care unit of the emergency department with the diagnosis of ACPE were included. Patients were placed on non-invasive mechanical ventilators with an oronasal mask under the nCPAP/PS and nSIMV modes. Pulse and respiratory rate, systolic and diastolic blood pressure and Glasgow Coma Scores(GCS), HACOR(heart rate, acidosis, consciousness, oxygenation and respiratory rate) scores, pH, PaCO2, PaO2/FiO2 and lactate at the time of admission and at 30 and 60 min were evaluated. RESULTS: Twenty-two patients were recruited, nCPAP/PS mode was 10 and nSIMV mode was 12. Although there was no statistically significant difference between the two groups in terms of the change in the relevant parameters from admission to 60 min, the decreases in PaCO2 and lactate levels (31.4% vs. 21.2%, p = 0.383; 68.8% vs. 47.1%, p = 0.224; respectively) and the increase in PaO2 and PaO2/FiO2 values (34% vs. 14.2%, p = 0.710 and 132.1% vs. 52.7%, p = 0.073; respectively) were higher in the nSIMV group. CONCLUSION: The nSIMV mode is as effective as the nCPAP/PS mode in the treatment of patients with ACPE. We believe that the nSIMV mode can be preferable, particularly in patients with hypercarbia who have relatively lower GCS and oxygenation.

Prevalence of rare F5 variants in general population from Bosnia and Herzegovina.

Human gene F5, encoding coagulation factor V, was previously reported to be highly polymorphic. Apart from FV Leiden, several other rare variants have been detected in clinical practice and associated with thrombotic events, especially in cases when patient's phenotype and FV Leiden genotype were not in agreement. In this study, the prevalence of 17 rare F5 variants has been studied on a sample of 130 healthy adult individuals from the general Bosnian-Herzegovinian population. DNA was isolated from buccal swab samples, while genotyping was performed using MALDI-TOF MS method. The results have shown that Asp2194Gly and Met2120Thr are polymorphic in the study population with minor allele frequencies of 0.077 and 0.073, respectively. Additionally, these two variants were mutually exclusive with FV Leiden and none of them was positively associated with participants' family history of cardiovascular or cerebrovascular diseases. While the obtained results are in agreement with previously reported data for the general Caucasian populations, it is worth noting that only two rare F5 variants were detected in the study population, albeit at considerable frequencies. Still, scientific information on rare F5 variants is rather scarce and further studies aiming to assess functional importance of these variants, as well as their role as prothrombotic factors are necessary.

The effect of music on state anxiety in patients undergoing extracorporeal shockwave lithotripsy.

AIM: Extracorporeal shockwave lithotripsy is a commonly used method to break down kidney stones in urology clinics. This study aims to investigate whether or not listening to music is effective against state anxiety in patients undergoing kidney stone treatment with this method. METHODS: A total of 80 patients (50 males, 30 females) undergoing extracorporeal shockwave lithotripsy for the first time at our clinic were included in the study. The first group (24 patients) listened to instrumental classical music through headphones 20 minutes before the procedure, while the second group (28 patients) listened to instrumental classical music during the procedure. The third group (28 patients) was the control group and consisted of patients who did not listen to music before or during the procedure. Patients were administered a state-trait anxiety inventory test to measure state anxiety after the process, and their results were compared. RESULTS: While there was a significant difference in state-trait anxiety inventory scores between patients who listened to music before/during the procedure and the control group, there was no significant difference between patients who listened to music before and those who listened to music during the procedure. Assessment of randomisation showed groups achieved homogeneity. CONCLUSION: Among the groups homogeneously distributed according to age and gender, significantly lower anxiety scores of groups that listened to music compared with the control group have provided supporting data to be open-minded and exploratory about increasing patient tolerability and comfort during these potentially pain-inducing procedures.

Do Social and Environmental Factors Affect the Emergency Service Admission Characteristics of Preschool-Aged Pediatric Trauma Patients?: A Prospective Study.

OBJECTIVE: Studies related to the epidemiology of trauma play a major role in determining the health status of the communities living in the vicinity of the centers that they are conducted. We have found no epidemiological study related to emergency service admission conducted only on preschool-aged children in the literature. Our aim was to determine characteristics of trauma in this age group, to analyze encountered trauma types, and to investigate possible associations among epidemiological factors, characteristics of the trauma victims, and trauma itself in pediatric patients admitted to our emergency service. METHODS: We conducted a prospective study with patients aged 66 months and younger, admitted to Emergency Service of Istanbul Kanuni Sultan Suleyman Training and Research Hospital between July 1, 2015, and December 31, 2015. Data related to age, sex, occupational status of parents, number of siblings, Glasgow coma scale score, transport mode, admission time period of the day, general health status, type of trauma, the trauma site, involved body regions, radiologic imaging and laboratory results, consultations, clinical diagnosis and outcome, duration of emergency service stay, and treatment cost were collected and statistically analyzed. RESULTS: A total of 688 preschool-aged cases were admitted owing to trauma. The major mode of transport was a private vehicle (98.3%), and the major cause was falling (64.0%). The major traumatized body region was head and neck (51.0%), and the major diagnosis was soft tissue trauma (90.1%). The average duration of stay was 122.01 minutes and affected by sibling number, trauma type, and employment status. The total service fee was interrelated with the type of trauma and the site that trauma occurred; it also was strongly correlated with duration of emergency service stay. CONCLUSIONS: Our results suggest that both in-hospital and social/environmental aspects should be improved to reduce the clinical and social burden of trauma.

Population study of thrombophilic markers and pharmacogenetic markers of warfarin prevalence in Bosnia and Herzegovina.

AIM: To investigate the prevalence of common genetic variants that can serve as markers of thrombophilia and warfarin pharmacogenetics in Bosnia and Herzegovina. METHODS: The study was performed between August and October 2017 on 130 healthy unrelated adult volunteers from Bosnian-Herzegovinian population sample. The prevalence of the following genetic variants was determined: F5 c.1601G>A (factor V Leiden), F2 c.*97G>A (factor II or prothrombin mutation), F13A1 (factor XIII) c.103G>T, MTHFR (methylenetetrahydrofolate reductase) c.665C>T and c.1286A>C, as well as PAI-1 (plasminogen activator inhibitor 1) c.-816A>G and c.-844G>A as markers of thrombophilia risk, and *2 and *3 alleles of CYP2C9 (cytochrome P450 2C9) and five variants of VKORC1 (vitamin K epoxide reductase complex subunit 1) as markers of warfarin pharmacogenetics. DNA was isolated from buccal swabs using salting out method, while genotyping was performed using matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry. RESULTS: Minor allele frequencies for two main thrombophilia risk factors, F5 c.1601G>A and F2 c.*97G>A were 0.023 and 0.008, respectively. Combined data for the markers of warfarin pharmacogenetics imply that 57.4% study participants can be expected to metabolize warfarin at an extensive, 40.3% at intermediate, and 2.3% at a poor rate. CONCLUSION: This study reports the first extensive population genetic data for thrombophilia and warfarin pharmacogenetic markers in Bosnia and Herzegovina. Allele frequencies of genetic variants are within the general average for European populations, and their presence implies the necessity of introduction of personalized medicine in warfarin-mediated antithrombotic therapy.

Acceptance of Adjuvant and Neoadjuvant Chemotherapy in Muscle-Invasive Bladder Cancer in Germany: A Survey of Current Practice.

BACKGROUND: Guidelines support the use of neoadjuvant (NAC) and adjuvant (AC) chemotherapy in muscle-invasive bladder cancer. However, data from North America reported the underutilization of NAC in favor of AC despite the lower level of scientific evidence supporting AC. We aimed to assess current practice patterns of NAC and AC in -Germany. METHODS: A 15-question online survey was developed and sent via email newsletters to members of the -German Association of Urology and of the German Society of Residents in Urology in October 2016 to analyze current practice patterns. RESULTS: The survey yielded 141 individual responses from 61 different German urology departments. Eighty-nine (69.0%) and 119 (93.0%) participants were stated to regularly use NAC and AC respectively. The number of participants who were stated to use NAC and AC regularly was not associated with the type of institution (academic vs. nonacademic), number of hospital beds, and number of cystectomies performed annually. Gemcitabine/cisplatin combination chemotherapy was named as the primarily used NAC regimen by 80 (95%) respondents. The median number of administered cycles was 3 for NAC and 4 for AC. In the case of cisplatin ineligibility, combination chemotherapy with gemcitabine/carboplatin was the most common regimen. Respondents stated that chemotherapy was generally administered by urologists (81% for NAC and 85% for AC). CONCLUSIONS: Our survey of current practice shows a high acceptance rate of NAC in Germany, which was independent of the type of institution. Although the scientific level of evidence for AC is lower, it still seems to be more widely accepted than NAC. NAC and AC were generally administered by urologists.

Use of radiography and ultrasonography for nasal fracture identification in children under 18 years of age presenting to the ED.

PURPOSE: To compare the diagnostic value of ultrasonography (USG), which is rapid, inexpensive, simple, and does not involve radiation, with that of direct radiography for identifying fractures in the nasal bones of pediatric patients presenting in the emergency department with nasal trauma. EQUIPMENT AND METHODS: Patients under 18years old presenting with nasal trauma at the emergency department included prospectively. The patients' age and sex distribution, trauma type, GCS, physical examination findings, direct radiography, and USG results were recorded. The physical examination made by the emergency medicine specialist on arrival was accepted as the gold standard for diagnosis. FINDINGS: In total, 133 patients, 34.6% female and 65.4% male, were included in this study. The average patient age was 7.44±5.05years, with the greatest proportion (21.8%, n=29) of patients in the age ranges of 0-2 and 6-8years. The most frequently observed finding on physical examinations was swelling (51.1%, n=68). In total, 50 (37.6%) patients had nasal fractures according to their first physical examination, which was performed by emergency medicine specialists. That is, fractures were detected by direct radiography in only 11 of the 34 cases who were diagnosed with fractures by USG. CONCLUSIONS: We consider that USG should be preferred over direct radiography for use at the bedside of pediatric patients who present at emergency department with nasal trauma, because of its superior diagnostic ability and the lack of a requirement for radiation.

Molecular diversity of 23 Y-chromosome short tandem repeat loci in the population of Tuzla Canton, Bosnia and Herzegovina.

BACKGROUND: Tuzla Canton is the most populated region in the ethnically mixed territory of Bosnia and Herzegovina, whose genetic analysis could provide an insight into past demographic events. AIM: Analysis of 23 Y-chromosome STR markers in the population of Tuzla Canton and investigation of the genetic relationship of the male population of the Tuzla Canton and that of the larger Bosnian and Herzegovinian population as well as neighbouring and other European populations. SUBJECTS AND METHODS: The study was conducted among 100 unrelated healthy adult males from Tuzla Canton that have been genotyped using 23 Y-STR loci included in the PowerPlex Y23 kit. Statistical parameters such as haplotype diversity and allele frequencies were calculated, as well as the Rst-based genetic distances between the new dataset and those from Bosnia and Herzegovina and elsewhere, which were then visualised through multi-dimensional scaling plot and neighbour-joining phylogenetic tree analyses. RESULTS: The PowerPlex Y23 kit has shown high discrimination capacity, as all 100 individuals have unique haplotypes. The newly incorporated loci seem to be highly informative. Population comparison reveals no statistically significant differences between the study population and the general Bosnian-Herzegovinian population, and between the study population and neighbouring populations. CONCLUSION: These results could be used as an additional investigation of the genetic relationship between the regional populations in Bosnia and Herzegovina and neighbouring human populations, as well as for further human population and forensic genetics studies.

Y-Chromosome Haplogroups in the Bosnian-Herzegovinian Population Based on 23 Y-STR Loci.

In a study of the Bosnian-Herzegovinian (B&H) population, Y-chromosome marker frequencies for 100 individuals, generated using the PowerPlex Y23 kit, were used to perform Y-chromosome haplogroup assignment via Whit Athey's Haplogroup Predictor. This algorithm determines Y-chromosome haplogroups from Y-chromosome short tandem repeat (Y-STR) data using a Bayesian probability-based approach. The most frequent haplogroup appeared to be I2a, with a prevalence of 49%, followed by R1a and E1b1b, each accounting for 17% of all haplogroups within the population. Remaining haplogroups were J2a (5%), I1 (4%), R1b (4%), J2b (2%), G2a (1%), and N (1%). These results confirm previously published preliminary B&H population data published over 10 years ago, especially the prediction about the B&H population being a part of the Western Balkan area, which served as the Last Glacial Maximum refuge for the Paleolithic human European population. Furthermore, the results corroborate the hypothesis that this area was a significant stopping point on the "Middle East-Europe highway" during the Neolithic farmer migrations. Finally, since these results are almost completely in accordance with previously published data on B&H and neighboring populations generated by Y-chromosome single nucleotide polymorphism analysis, it can be concluded that in silico analysis of Y-STRs is a reliable method for approximation of the Y-chromosome haplogroup diversity of an examined population.

Serum Visfatin Levels in Ulcerative Colitis.

BACKGROUND: Previous studies have suggested that adipokines play a role in inflammatory bowel disease by inducing proinflammatory cytokines, but it is uncertain whether visfatin is causally involved in ulcerative colitis (UC). We evaluated visfatin levels in patients who presented with UC flares before and after treatment. METHODS: In this cohort study, we assessed 31 patients with UC in the activation period and remission in the same patients after treatment, and a healthy control group, consisting of 29 persons, at a single academic medical centre between 2010 and 2013. Disease severity was evaluated clinically using Trulove and Witt's criteria. RESULTS: Serum visfatin levels did not vary according to the extent of disease and were significantly higher in patients in the activation period (7.77 ± 2.41 ng/ml) than in remission (6.18 ± 2.04 ng/ml) and the healthy controls (6.54 ± 2.20 ng/ml; P < 0.01 and < 0.05, respectively). In a comparison of patients in the inactive period with the control group, there was no statistically significant difference (P > 0.05). To assess activation of the disease, a visfatin cut-off point for active UC was determined as 6.40, with sensitivity, specificity, positive predictive value (PPV) and negative predictive values (NPV) of 72%, 52%, 66.7% (43.0-85.4) and 50.0% (29.1-70.9), respectively. CONCLUSIONS: The visfatin level was higher in the active group than in post-treatment remission and the healthy control group. Sensitivity and specificity were similar to other inflammatory markers for assessing clinical activity, which did not improve clinical outcomes in patients with acute respiratory distress syndrome (ARDS). These findings did not provide a rationale for assessment of UC activation.

Prediction of the Y-Chromosome Haplogroups Within a Recently Settled Turkish Population in Sarajevo, Bosnia and Herzegovina.

Analysis of Y-chromosome haplogroup distribution is widely used when investigating geographical clustering of different populations, which is why it plays an important role in population genetics, human migration patterns and even in forensic investigations. Individual determination of these haplogroups is mostly based on the analysis of single nucleotide polymorphism (SNP) markers located in the non-recombining part of Y-chromosome (NRY). On the other hand, the number of forensic and anthropology studies investigating short tandem repeats on the Y-chromosome (Y-STRs) increases rapidly every year. During the last few years, these markers have been successfully used as haplogroup prediction methods, which is why they have been used in this study. Previously obtained Y-STR haplotypes (23 loci) from 100 unrelated Turkish males recently settled in Sarajevo were used for the determination of haplogroups via 'Whit Athey's Haplogroup Predictor' software. The Bayesian probability of 90 of the studied haplotypes is greater than 92.2% and ranges from 51.4% to 84.3% for the remaining 10 haplotypes. A distribution of 17 different haplogroups was found, with the Y- haplogroup J2a being most prevalent, having been found in 26% of all the samples, whereas R1b, G2a and R1a were less prevalent, covering a range of 10% to 15% of all the samples. Together, these four haplogroups account for 63% of all Y-chromosomes. Eleven haplogroups (E1b1b, G1, I1, I2a, I2b, J1, J2b, L, Q, R2, and T) range from 2% to 5%, while E1b1a and N are found in 1% of all samples. Obtained results indicate that a large majority of the Turkish paternal line belongs to West Asia, Europe Caucasus, Western Europe, Northeast Europe, Middle East, Russia, Anatolia, and Black Sea Y-chromosome lineages. As the distribution of Y-chromosome haplogroups is consistent with the previously published data for the Turkish population residing in Turkey, it was concluded that the analyzed population could also be recognized as a representative sample of the Turkish population residing in Turkey.

Neutrophil-lymphocyte ratio in patients with familial Mediterranean fever.

BACKGROUND: Blood neutrophil-to-lymphocyte (N/L) ratio is an indicator of the overall inflammatory status of the body, and an alteration in N/L ratio may be found in patients with familial Mediterranean fever (FMF). The aim of this study was to investigate the interrelationship between N/L ratio and FMF. METHODS: One hundred and fifteen patients and controls were enrolled in the study. The cases in the study were categorized as FMF with attack, FMF with attack-free period, and controls. The neutrophil and lymphocyte counts were recorded, and the N/L ratio was calculated from these parameters. All patients were diagnosed according to Tel Hashomer criteria. RESULTS: A total of 79 FMF patients were included in the study and all subjects were receiving colchicine treatment at the time. The serum N/L ratios of active patients were significantly higher than those of attack-free FMF patients and controls (P < 0.001). The optimum N/L ratio cut-off point for active FMF was 2.63 with sensitivity, specificity, positive predictive value, and negative predictive value of 0.62 (0.41-0.80), 0.85 (0.72-0.93), 0.67 (0.44-0.85), and 0.82 (0.69-0.91), respectively. The overall accuracy of the N/L ratio in determination of FMF patients during attack was 71%. CONCLUSION: Our results demonstrate that N/L ratio is higher in patients with active FMF compared with FMF patients in remission and controls, and a cut-off value of 2.63 can be used to identify patients with active FMF.

Red blood cell distribution width as a non-invasive marker for the assessment of inflammation in non-alcoholic steatohepatitis.

BACKGROUND/AIMS: The aim of this study was to assess the association between red cell distribution width and inflammation in biopsy proven non-alcoholic steatohepatitis. METHODOLOGY: Fifty four subjects with non-alcoholic steatohepatitis and thirty nine controls were enrolled for the study. Liver biopsy specimens were scored by using non-alcoholic fatty liver disease activity score by a single experienced liver pathologist. RESULTS: Red cell distribution width was higher in the severe inflammation group in non-alcoholic steatohepatitis (p < 0.05). The areas under the receiver operating characteristic curves for the predictive performance of aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transferase and red cell distribution width in identifying inflammation in non-alcoholic steatohepatitis were 0.55 (0.41-0.68), 0.51 (0.37-0.64), 0.53 (0.39-0.67) and 0.73 (0.59-0.84) respectively and the differences of these values between red cell distribution width and other parameters were found to be statistically significant (p < 0.05). To determine the grading of inflammation, the specificity for using the red cell distribution width as an indicator in non-alcoholic steatohepatitis patients was calculated to be 73.3%, with 79.5% sen- sitivity. CONCLUSION: Red cell distribution width was a sensitive and specific method for the assessment of the inflammation in patients with non-alcoholic steatohepatitis.

Identification of human remains from the Second World War mass graves uncovered in Bosnia and Herzegovina.

AIM: To present the results obtained in the identification of human remains from World War II found in two mass graves in Ljubuski, Bosnia and Herzegovina. METHODS: Samples from 10 skeletal remains were collected. Teeth and femoral fragments were collected from 9 skeletons and only a femoral fragment from 1 skeleton. DNA was isolated from bone and teeth samples using an optimized phenol/chloroform DNA extraction procedure. All samples required a pre-extraction decalcification with EDTA and additional post-extraction DNA purification using filter columns. Additionally, DNA from 12 reference samples (buccal swabs from potential living relatives) was extracted using the Qiagen DNA extraction method. QuantifilerTM Human DNA Quantification Kit was used for DNA quantification. PowerPlex ESI kit was used to simultaneously amplify 15 autosomal short tandem repeat (STR) loci, and PowerPlex Y23 was used to amplify 23 Y chromosomal STR loci. Matching probabilities were estimated using a standard statistical approach. RESULTS: A total of 10 samples were processed, 9 teeth and 1 femoral fragment. Nine of 10 samples were profiled using autosomal STR loci, which resulted in useful DNA profiles for 9 skeletal remains. A comparison of established victims' profiles against a reference sample database yielded 6 positive identifications. CONCLUSION: DNA analysis may efficiently contribute to the identification of remains even seven decades after the end of the World War II. The significant percentage of positively identified remains (60%), even when the number of the examined possible living relatives was relatively small (only 12), proved the importance of cooperation with the members of the local community, who helped to identify the closest missing persons' relatives and collect referent samples from them.

Non-alcoholic fatty liver disease in patients with migraine.

Evidence suggests that migraine is associated with metabolic syndrome, which is also implicated in non-alcoholic fatty liver disease (NAFLD). Reported for the first time, we aimed to investigate the relationship between migraine and NAFLD in patients with migraine. A total of 90 consecutive migraine patients were enrolled in this cross-sectional study. The diagnosis of migraine was determined according to the International Classification of Headache Disorders-II diagnostic criteria. The diagnosis of NAFLD was based on abdominal ultrasonography findings. Anthropometric indices and the homeostasis model assessment of insulin resistance (HOMA-IR) were calculated, and serum insulin level measurements and other biochemical analyses were performed for each subject. The measurements of body mass index and waist circumference were significantly higher in migraine patients with NAFLD than in those without NAFLD (p < 0.001). Regarding the laboratory results, insulin (p = 0.024), alanine aminotransferase (p = 0.027), and triglyceride levels (p = 0.001) and the HOMA-IR (p = 0.039) were higher in migraineurs with NAFLD than in those without NAFLD. Among the headache characteristics, the presence of aura was higher, and disease and attack durations were significantly longer in migraineurs with NAFLD than in those without NAFLD (p = 0.005, p = 0.024, and p = 0.023; respectively). However, the headache characteristics did not correlate with either the hepatosteatosis grade or HOMA-IR in migraine patients (p > 0.05). Our results show that NAFLD may present in migraine patients with higher frequency of auras and longer disease and attack durations.

Markers of endothelial damage and repair in Takayasu arteritis: are they associated with disease activity?

The current clinical and laboratory parameters of Takayasu arteritis (TA) are insufficient for proper assessment of disease activity. The aims of this study were to investigate the markers of endothelial injury and repair, including circulating endothelial cell (CEC), circulating endothelial progenitor cell (CEPC) and vascular endothelial growth factor (VEGF), and evaluate their associations with disease activity in patients with TA. Thirty-two patients with TA and 30 healthy age- and sex-matched controls were included in this study. Disease activity was assessed in TA patients using various tools, including Kerr's criteria, the Indian Takayasu's Arteritis Scoring (ITAS2010) and physician's global assessment (PGA). CECs and CEPCs were measured by flow cytometry, and VEGF was measured using an enzyme-linked immunosorbent assay. The CEC level was found to be higher in TA patients than in the healthy controls (HC) (p < 0.001). There was no significant difference in CEC level between the active and inactive patients, but its level was slightly correlated with C-reactive protein (CRP) level. CEPC and VEGF levels in TA patients with active disease were higher than those in the inactive patients and HC. CEPC and VEGF levels were positively correlated with ITAS-CRP and PGA scores. This study shows increased level of CEC in patients with TA. It also suggests that the CEPC and VEGF levels may be correlated with disease activity.

Genetic analysis of haplotype data for 23 Y-chromosome short tandem repeat loci in the Turkish population recently settled in Sarajevo, Bosnia and Herzegovina.

AIM: To explore the distribution and polymorphisms of 23 short tandem repeat (STR) loci on the Y chromosome in the Turkish population recently settled in Sarajevo, Bosnia and Herzegovina and to investigate its genetic relationships with the homeland Turkish population and neighboring populations. METHODS: This study included 100 healthy unrelated male individuals from the Turkish population living in Sarajevo. Buccal swab samples were collected as a DNA source. Genomic DNA was extracted using the salting out method and amplification was performed using PowerPlex Y 23 amplification kit. The studied population was compared to other populations using pairwise genetic distances, which were represented with a multi-dimensional scaling plot. RESULTS: Haplotype and allele frequencies of the sample population were calculated and the results showed that all 100 samples had unique haplotypes. The most polymorphic locus was DYS458, and the least polymorphic DYS391. The observed haplotype diversity was 1.0000 ± 0.0014, with a discrimination capacity of 1.00 and the match probability of 0.01. Rst values showed that our sample population was closely related in both dimensions to the Lebanese and Iraqi populations, while it was more distant from Bosnian, Croatian, and Macedonian populations. CONCLUSION: Turkish population residing in Sarajevo could be observed as a representative Turkish population, since our results were consistent with those previously published for the homeland Turkish population. Also, this study once again proved that geographically close populations were genetically more related to each other.
