    Objectives: The aim of our study is the comparison of the results of conventional smear (CC) technique and liquidbased cytology (LBC) technique used as cervical cancer screening methods. Material and methods: The results of 47954 patients submitted to smear screening in our gynecology clinic between January 2008 and December 2014 have been studied. The smear results have been divided into two groups CC and LBC according to the technique used. Results: When considering the distribution within CC group, the results were as follows: intraepithelial cell abnormalities 2,0% (n=619), insufficient sample for analysis 2,1% (n=660), Atypical squamous cells of undetermined significance (ASC-US) 1.8% (n=554), Low grade squamous intraepithelial lesion (LGSIL) 0.1% (n=35), High grade squamous intraepithelial lesion (HGSIL) 0.1% (n=16), Atypical squamous cells – cannot exclude HGSIL (ASC-H) 0.029% (n=9), Atypical glandular cells- not other wise specified (AGC-NOS) 0.012% (n=4), squamous carcinoma 0.003% (n=1). When considering the distribution in LBC group, the results were as follows: intraepithelial cell abnormalities2.1% (n=357), insufficient sample for analysis 0.9% (n=144), ASC-US 1.8% (n=296), LGSIL 0.2% (n=38), HGSIL 0.1% (n=8), ASC-H 0.1% (n=10), AGC-NOS 0.017% (n=3), squamous carcinoma 0.011% (n=2). Conclusions: Although the rates of epithelial cell abnormalities are similar for both tests, LSIL results are more frequently observed in LBC technique. In LBC technique, the number of insufficient sample for analysis is quite low compared to CC group and thus constitutes an advantage.  Cel pracy: Celem badania było porównanie wyników konwencjonalnej (CC) i płynnej cytologii (LBC) stosowanej w skriningu raka szyjki macicy. Materiał i metoda: Przeanalizowano wyniki od 47954 pacjentek objętych cytologicznym badaniem skriningowym w naszym oddziale ginekologicznym w okresie od stycznia 2008 do grudnia 2014. Wyniki cytologiczne podzielono na dwie grupy CC i LBC w zależności od techniki pobierania. Wyniki: W grupie CC wyniki przedstawiały się nastepująco: nieprawidłowości komórek śródnabłonkowych 2,0% (n=619), nieodpowiednia próbka do analizy 2,1% (n=660), ASC-US 1.8% (n=554), LGSIL 0.1% (n=35), HGSIL 0.1% (n=16), ASC-H 0.029% (n=9), AGC-NOS 0.012% (n=4), rak płaskonabłonkowy 0.003% (n=1). W grupie LBC wyniki przedstawiały się następująco: nieprawidłowości komórek śródnabłonkowych 2.1% (n=357), nieodpowiednia próbka do analizy 0.9% (n=144), ASC-US 1.8% (n=296), LGSIL 0.2% (n=38), HGSIL 0.1% (n=8), ASC-H 0.1% (n=10), AGC-NOS 0.017% (n=3), rak płaskonabłonkowy 0.011% (n=2). Wnioski: Chociaż odsetek nieprawidłowości komórek śródnabłonkowych jest podobny dla obu testów, wyniki LSIL są częściej obserwowane w technice LBC. W metodzie LBC liczba próbek nieodpowiednich do analizy jest dość niska w porównaniu do grupy CC, stąd jest to jej niewątpliwa zaleta.

    A New Energy-Aware Cluster Head Selection Algorithm for Wireless Sensor Networks

    Wireless Sensor Networks (WSN) always need energy due to the areas they are used. The use of sensors is quite wide, and in some of the places, it is very difficult or impossible to restore the energy of the sensors such as in war areas or in wildlife. Therefore, they need to use their existing energy most efficiently. For WSN, the role of clustering is crucial in terms of using less energy. Selecting the most appropriate sensor node as cluster head (CH) according to the criteria determined within the clustered sensors reduces the energy consumption. In this study, a new clustering algorithm is proposed for WSNs to reduce energy consumption and thus prolong the life of the WSNs. The Cluster Centered Cluster Head Selection Algorithm (C3HA), which is developed in line with this objective, gives a new perspective to the selection of CH while creating a more efficient WSN than the popular clustering algorithms LEACH, and PEGASIS. This developed algorithm is compared with popular algorithms and proved to be more efficient in terms of fast and accurate CH selection.WOS:0006907271000012-s2.0-8511375996

    Objective: The aim of this study was to examine sociodemografic variables, diagnosis of mental disorders, and factors associated with the mental disorders of sexually abused children and adolescents who referred to child psychiatry outpatient department with the request of criminal report. Methods: In our study, sexually abused 234 children and adolescents (181 girls and 53 boys) aged 3-18 years who referred for criminal reports were evaluated. Case files, social observation reports, and criminal reports were examined retrospectively by the researchers. Results: Touching to the body for the sexual arousal was the most reported type of the sexual abuse (31.2%). More than one sexual abuse was established in 44.9% of cases. 97.9% of the abusers were males, 73.6% were acquaintance, and 14.5% were a family member. 20.1% of cases were sexually abused by more than one abusers and 54.3% were accompanied by violence. It was determined that 67.1% of cases had at least one mental disorder diagnosis. Children and adolescents who have been sexually abused by more than one abusers, who have been abused by a family member, whose abuse involved, penetration and violence or who have been abused repetitively are at greater risk of developing mental problems. Discussion: Sexual abuse causes long-term emotional and behavioral problems in children. Some types of sexual abuse may lead to more serious results. Moreover, individual and family characteristics of the victim, and level of social support influence problems related to sexual abuse

    The aim of the present study was to investigate the factors associated with unintentional injury in children newly diagnosed with attention-deficit/hyperactivity disorder (ADHD). One thousand four hundred and thirty children between the ages of 6 and 18 who were diagnosed with ADHD for the first time in child psychiatry outpatient clinics were included in the present study. The socio-demographic information of the children, their developmental histories, chronic physical health conditions, comorbid psychiatric disorders, and information obtained via the Turgay DSM-IV-based Child and Adolescent Disorders Screening and Rating Scale were examined retrospectively. It was determined that 12.8% of the children (n = 183) experienced unintentional injury. It was established that age, male gender, disruptive behavioural problems, and low education levels among mothers were predictive of unintentional injuries. The results of the present study suggest that behavioural problems accompanying ADHD and comorbid psychiatric disorders are important in terms of unintentional injuries

    Fundamento: A hipertensão arterial é o fator de risco mais prevalente e modificável para a fibrilação atrial. A sobrecarga de pressão no átrio esquerdo induz alterações fisiopatológicas que ocasionam alterações na função contrátil e nas propriedades elétricas. Objetivo: Nesse estudo, o objetivo foi avaliar a função do átrio esquerdo em pacientes hipertensos para determinar a associação entre a função atrial esquerda e a fibrilação atrial paroxística (FAP). Método: Foram estudados 57 pacientes hipertensos (idade: 53 ± 4 anos, fração de ejeção do ventrículo esquerdo: 76 ± 6,7%), incluindo 30 pacientes consecutivos com FAP e 30 indivíduos de controle pareados por idade. Os volumes do átrio esquerdo (AE) foram medidos através do método biplano de Simpson modificado. Foram determinados três tipos de volume do AE: volume máximo do AE (AEVmax), contração atrial prematura do AE (AEVpreA) e volume mínimo do AE (AEVmin). Foram calculadas as funções de esvaziamento do AE. Volume total de esvaziamento do AE = AEVmax - AEVmin e a FEtotal do AE = (AEVmax - AEVmin)/AEVmax, volume de esvaziamento passivo do AE = AEVmax-AEVpreA, e a FE do AE = (AEVmax - AEVpreA)/AEVmax, o volume de esvaziamento ativo do AE = AEVpreA- AEVmin e a FE ativa do AE = (AEVpreA - AEVmin)/AEVpreA. Resultados: O período hipertenso é maior no grupo de hipertensos com FAP. O AEVmax aumentou significativamente no grupo de hipertensos com FAP quando comparado ao grupo de hipertensos sem FAP (p = 0,010). A FEAE diminuiu significativamente no grupo de hipertensos com FAP em comparação com o grupo de hipertensos sem FAP (p = 0,020). A' diminuiu no grupo de hipertensos com FAP quando comparado com hipertensos sem FAP (p = 0,044). Conclusão: O volume aumentado do AE e função de esvaziamento ativa do AE prejudicada foram associados com a FAP em pacientes hipertensos não tratados. Um período hipertenso mais longo está associado com a FAP

    OBJECTIVES: The red blood cell distribution width has been associated with an increased risk of cardiovascular events. In the present study, we assessed the relationship between red cell distribution width values and cardiac troponin I levels in patients admitted with non-ST-elevation acute coronary syndrome. METHODS: We analyzed blood parameters in 251 adult patients who were consecutively admitted to the intensive coronary care unit with non-ST-elevation acute coronary syndrome over a 1-year period. For all patients, a baseline blood sample was collected for routine hematological testing. Cardiac troponin I was measured at baseline and after 6 h. The patients were diagnosed with non-ST-elevation myocardial infarction or unstable angina based on the elevation of cardiac troponin I levels. RESULTS: The red cell distribution width was higher in the group with non-ST-elevation myocardial infarction compared with the patient group with unstable angina (14.6±1.0 vs 13.06±1.7, respectively; p = 0.006). Coronary thrombus was detected more frequently in the group of patients with non-ST-elevation myocardial infarction than in the patients with unstable angina (72% vs 51%, respectively; p = 0.007). Using receiver operating characteristic curve analysis for the prediction of non-ST-elevation myocardial infarction based on the red cell distribution width, the area under the curve was 0.649 (95% confidence interval: 0.546-0.753; p = 0.006), suggesting a modest model for the prediction of non-ST-elevation myocardial infarction using the red cell distribution width. At a cut-off value of 14%, the sensitivity and specificity of the red cell distribution width were 73% and 59%, respectively. Additionally, the red cell distribution width was positively correlated with cardiac troponin I (r = 0.19; p = 0.006). CONCLUSION: A greater baseline red cell distribution width value was associated with myocardial injury and elevated cardiac troponin I levels in non-ST-elevation acute coronary syndrome. Therefore, the red cell distribution width could be considered for risk stratification of acute coronary syndrome patients admitted to emergency departments
