RESUMEN

OBJECTIVES: The incidence of obesity and obesity-assosiated pathologies continues to increase with profound adverse effects on health status in the developed countries. BACKGROUND: We aimed to investigate the effect of high fat diet on the adrenal gland morphology. METHODS: We fed the mice with either high-fat diet (60 % kcal from fat) or low-fat diet (10 % kcal from fat) for nine weeks. Unbiased stereological methods were used to evaluate the adrenal gland morphology. The sections were evaluated using Cavalieri's method and volume fraction approach. We calculated mean volume of adrenal gland, mean volume of adrenal medulla, VVadrenal medulla/adrenal gland, mean diameter of cromaffin cells, number of chromaffin cells in per unit volume (NVcc mm‒3), total number of cromaffin cells, VVzona glomerulosa/adrenal cortex, VVzona fasciculata/adrenal cortex , VVzona reticulosa/adrenal cortex. RESULTS: The weight of adrenal gland, body weight intraperitoneal adipose tissue and adrenal gland weight in the obese mice significantly increased when compared with the control group. No changes were observed in the mean volume of adrenal gland, mean volume of adrenal medulla, VVzona glomerulosa/adrenal cortex, VVzona fasciculata/adrenal cortex, total number of cromaffin cells and diameter of cromaffin cells. However, NVcc mm-3 and VVzona reticulosa/adrenal cortex in the obese mice considerably increased compared with the control group. CONCLUSION: The present results suggest that high fat diet adversely affects the adrenal gland morphology (Tab. 2, Fig. 6, Ref. 28).

RESUMEN

AIMS: The purpose of this study is to compare distal oesophagus of persons with and without gastric reflux in terms of bacterial load and presence of certain bacterial species. METHODS AND RESULTS: Two biopsy specimens were obtained from the distal oesophagus at 5 cm above the gastroesophageal junction of each of the 50 patients (20 with normal oesophagus and 30 with reflux oesophagitis) under endoscopic examination and used for histological examination and DNA isolation. We used a real-time PCR-based assay to quantify the bacterial load and the presence of certain bacterial species from one of the biopsy samples. The biopsy specimens taken from the patients with reflux oesophagitis were consistent with gastroesophageal reflux disease (GERD). The bacterial load did not significantly differ between the groups (P < 0·005). CONCLUSION: While there was no difference between the bacterial load in the two groups, variation was observed in bacterial species. Most of the bacteria identified in distal oesophagus of the patients with gastroesophageal reflux were Gram negative. SIGNIFICANCE AND IMPACT OF THE STUDY: The human oesophagus was considered sterile until quite recently. Molecular techniques displayed the presence of a diverse bacterial species in the oesophagus. Although it is known that dysbiosis in the oesophagus causes GERD, and that Barrett's oesophagus can trigger the development of oesophageal adenocarcinoma, its etiopathogenesis is not clear. A limited number of published studies support the importance of the present study.

RESUMEN

PURPOSE: The aim of this study is to determine the ability of emergency physicians' (EP) interpreting contrast-enhanced computed tomographies (CECTs) performed in patients diagnosed or suspected acute pancreatitis (AP), using the modified computed tomography severity index (MCTSI) scoring system. METHODS: This study was conducted in Training and Research Hospital's Emergency Department. From January 1, 2013 to April 30, 2016, patients whom performed CECT within 24 h of admission with diagnosis or suspicion of AP were reviewed retrospectively. One hundred eighteen patients were included in the study. Three-third-year EPs received education about CECT interpretation and MCTSI criteria. Each EP interpreted CECTs in a blinded manner. The EPs' performance of determining the CECTs with or without AP and scoring the CECTs with CTSI scoring system was investigated. RESULTS: The agreement (weighted kappa) between the EPs and the radiologists for determining CECTs positive for AP was 0.932 (p < 0.001), 0.864 (p < 0.001) and 0.949 (p < 0.001) for EP1, EP2 and EP3, respectively. The agreement for MCTSI scores was 0.649 (p < 0.001), 0.588 (p < 0.001) and 0.734 (p < 0.001). These values showed a significant relationship between the EPs and radiologists. CONCLUSIONS: EPs can diagnose the AP on CECTs and score CECTs with MCTSI scoring system correctly.

RESUMEN

OBJECTIVES: To explore possible factors explaining a low participation rate to breast cancer screening for Turkish women living in Antwerp, Belgium, and to develop ways to increase participation rate. MATERIAL AND METHODS: The authors used focus group discussions with Turkish women to explore their reasons to participate or not to participate in breast cancer screening. Groups consisted of four to six women. Inclusion criteria were: being female, having a Turkish origin, and age between 50 and 69 years. For each focus group, one Turkish women was invited and asked to invite five other women meeting the inclusion criteria. RESULTS: Three focus group discussions with in total 17 women have taken place. Six women had participated to all consecutive invitations for breast cancer screening. One woman had participated once, but not the next time she was invited. Ten women had never participated to screening mammography, although some of them had undergone diagnostic mammography. In all three focus groups, insufficient knowledge of the Dutch language, the unavailability of a professional interpreter, being careless about healthcare, and a negative influence of the husband, were the main reasons not to participate in breast cancer screening. Invitation letters are not read because they are in a language the woman does not understand. Less frequently mentioned obstacles were being on a holiday or being sick on the day of the scheduled mammography, fear of pain, considering an examination useless when not having any symptoms, being anxious for a positive result, and the physical distance to the screening center. Receiving an invitation in Turkish and knowing that a person speaking Turkish will be available at the screening center were proposed as possible measures to improve participation. CONCLUSION: The single most important reason why Turkish women living in Antwerp, Belgium, do not participate in breast cancer screening was a language problem; other reasons were a lack of knowledge concerning breast cancer screening and not worrying about breast cancer. The language barrier in this population of older women can possible be overcome by Turkish speaking personnel at the screening centers.

RESUMEN

The protective effect of quercetin on cisplatin-induced renal and testicular tissue damage was investigated using biochemical, histopathological and histological approaches. A total of 40 male rats were divided into 5 groups as follows: control; cisplatin alone; quercetin alone; cisplatin + quercetin; and quercetin + cisplatin. Cisplatin was administered to rats at a single dose of 7 mg kg(-1) intraperitoneal. Quercetin was administered by gavage daily for 10 days at dosage 50 mg kg(-1) . At the end of the study serum, total antioxidant capacity (TAC) levels and total oxidant status (TOS) were determined. Malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT) and xanthine oxidase (XO) were studied separately in serum, renal tissue and testicular tissue. Renal and testicular morphological alterations were assessed, histopathologically. Epididymal sperm concentration, motility and morphology were investigated. Testicular and renal TAC and TOS values did not alter significantly. Renal CAT levels were increased by cisplatin and cisplatin plus quercetin groups that is reversed by administration of quercetin before cisplatin. MDA, CAT, SOD ve XO levels of testicular tissue did not differ significantly. Cisplatin and cisplatin plus quercetin groups had decreased sperm motility ratio and increased abnormal spermatozoa. Quercetin partially reverses some of the cisplatin-related pathological effects on kidney and testis.

RESUMEN

The Aptima HPV assay (Hologic Gen-Probe, San Diego, CA) is an FDA-approved assay for detecting human papillomavirus (HPV) E6/E7 mRNA from 14 high-risk HPV types. This study evaluated the clinical performance of the Aptima HPV assay for cervical intraepithelial neoplasia of grade 2 or worse (CIN2+), relative to the high-risk HPV GP5+/GP6+ PCR, in a cross-sectional clinical equivalence analysis using the noninferiority score test with cervical samples from population-based screening, i.e., 69 cervical scraping samples from women with CIN2+ and 843 from women without evidence of CIN2+. In addition, intralaboratory reproducibility over time and interlaboratory agreement of the Aptima HPV assay results were assessed with another set of 548 cervical samples. The Aptima HPV assay showed a clinical sensitivity for CIN2+ of 94.2% (95% confidence interval [CI], 85.5 to 97.8%) and a clinical specificity for CIN2+ of 94.5% (95% CI, 92.8 to 95.9%); by comparison, these figures were 97.1% (95% CI, 89.1 to 99.3%) (67/69 samples) and 93.6% (95% CI, 91.7 to 95.0%) (785/839 samples), respectively, for GP5+/GP6+ PCR. The clinical sensitivity and specificity of the Aptima HPV assay were noninferior to those of GP5+/GP6+ PCR (P = 0.039 and 0.00016, respectively). In addition, high reproducibility of the Aptima HPV assay, as reflected by the intralaboratory reproducibility over time of 96.0% (95% CI, 94.4 to 97.3%) (526/548 samples; kappa = 0.89) and interlaboratory agreement of 96.7% (95% CI, 95.4 to 98.1%) (531/548 samples; kappa = 0.91), was found. Altogether, these data show that the Aptima HPV assay meets the cross-sectional clinical and reproducibility criteria of the international guidelines for HPV test requirements for cervical screening. Longitudinal data are needed to ensure that the long-term negative predictive value of this mRNA assay is similar to those of validated HPV DNA tests.

RESUMEN

Familial Mediterranean fever (FMF) is an autoimmune disease inherited as an autosomal recessive trait and is characterized by recurrent attacks of fever and sterile polyserositis. This study examined electrocardiographic ventricular repolarization parameters (QT interval and QT dispersion) in 38 FMF patients and 35 healthy controls. The QT interval was measured manually from the onset of QRS to the end of the T wave (return to the TP baseline). QT dispersion was defined as the difference between the maximum and minimum QT values, and corrected QT was calculated according to the Bazett formula. There were no significant differences between FMF patients and healthy control subjects in any parameter of ventricular repolarization; hence QT dispersion was not affected by FMF. Electrocardiographic assessment of QT interval and QT dispersion are, therefore, of little value for the evaluation of cardiac impairment and risk of arrhythmia in FMF patients.

RESUMEN

We compared the clinical performance of the PapilloCheck human papillomavirus (HPV) assay with that of the GP5+/6+-PCR method with an enzyme immunoassay readout (GP5+/6+-PCR-EIA) for the detection of high-risk HPV (hrHPV) types by the use of cervical samples originating from women in a population-based by the use of cervical screening cohort tested by combined cytology and GP5+/6+-PCR-EIA (POBASCAM trial). Specimens from a random sample of 1,437 controls (women ages 40 to 60 years with normal cytological findings and without evidence of cervical intraepithelial neoplasia grade 2 or higher [> or = CIN2] within up to 8 years of follow-up) and 192 cases (women ages 30 to 60 years in whom > or = CIN3 was detected within up to 3 years of follow-up) were subjected to analysis by the PapilloCheck method. When all 17 (probably) hrHPV types were taken into account, the PapilloCheck assay had a clinical sensitivity for the detection of > or = CIN3 of 96.4% (185/192 samples; 95% confidence interval [CI], 93.7 to 99.7) and a clinical specificity for the detection of > or = CIN2 of 96.3% (95% CI, 95.3 to 97.3). After restriction of the analysis by the PapilloCheck assay to the 14 hr HPV types targeted by GP5+/6+-PCR-EIA, the clinical sensitivity and clinical specificity values were 95.8% (95% CI, 92.8 to 98.8) and 96.7% (95% CI, 95.7 to 97.7), respectively. By comparison, these values were 96.4% (95% CI, 93.9 to 98.9) and 97.7% (95% CI, 96.9 to 98.5), respectively, for the GP5+/6+-PCR-EIA. When all 17 (probably) hrHPV types were included in the analysis, noninferiority score testing revealed that the clinical sensitivity of the PapilloCheck assay for the detection of > or = CIN3 was noninferior to that of the GP5+/6+-PCR-EIA (P < 0.0001), but the clinical specificity of the PapilloCheck assay for the detection of > or = CIN2 was inferior to that of the GP5+/6+-PCR-EIA (P = 0.08) when lower bounds of 90% for sensitivity and 98% for specificity were used. When the analysis was restricted to the 14 hrHPV types targeted by the GP5+/6+-PCR-EIA, both the clinical sensitivity and the clinical specificity of the PapilloCheck assay were noninferior to those of the GP5+/6+-PCR-EIA (noninferiority score test; P < 0.0001 and P = 0.007, respectively). Thus, when the findings obtained for the 14 hrHPV types detectable by the GP5+/6+-PCR-EIA are considered, the PapilloCheck assay is clinically compatible with the GP5+/6+-PCR-EIA.
