Dataset related to article "EUS elastography (strain ratio) and fractal-based quantitative analysis for the diagnosis of solid pancreatic lesions"
<p>This record contains raw data related to article ""EUS elastography (strain ratio) and fractal-based quantitative analysis for the diagnosis of solid pancreatic lesions</p> <p>EUS elastography is useful in characterizing solid pancreatic lesions (SPLs), and fractal analysis-based technology has been used to evaluate geometric complexity in oncology. The aim of this study was to evaluate EUS elastography (strain ratio) and fractal analysis for the characterization of SPLs.</p> <p>METHODS:</p> <p>Consecutive patients with SPLs were prospectively enrolled between December 2015 and February 2017. Elastographic evaluation included parenchymal strain ratio (pSR) and wall strain ratio (wSR) and was performed with a new compact US processor. Elastographic images were analyzed using a computer program to determine the 3-dimensional histogram fractal dimension. A composite cytology/histology/clinical reference standard was used to assess sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiver operating curve.</p> <p>RESULTS:</p> <p>Overall, 102 SPLs from 100 patients were studied. At final diagnosis, 69 (68%) were malignant and 33 benign. At elastography, both pSR and wSR appeared to be significantly higher in malignant as compared with benign SPLs (pSR, 24.5 vs 6.4 [P < .001]; wSR, 56.6 vs 15.3 [P < .001]). When the best cut-off levels of pSR and wSR at 9.10 and 16.2, respectively, were used, sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiver operating curve were 88.4%, 78.8%, 89.7%, 76.9%, and 86.7% and 91.3%, 69.7%, 86.5%, 80%, and 85.7%, respectively. Fractal analysis showed a significant statistical difference (P = .0087) between the mean surface fractal dimension of malignant lesions (D = 2.66 ± .01) versus neuroendocrine tumor (D = 2.73 ± .03) and a statistical difference for all 3 channels red, green, and blue (P < .0001).</p> <p>CONCLUSIONS:</p> <p>EUS elastography with pSR and fractal-based analysis are useful in characterizing SPLs.</p>

Association between neutrophil to lymphocyte ratio and carotid artery wall thickness in healthy pregnant women
<p>Raw data related to the article.</p> <p>Abstract</p> <p><strong>Objective: </strong>Pregnancy may elicit a state of mild inflammation that might affect, either directly or indirectly, haematological parameters associated with systemic inflammation. In particular, both Neutrophil-to-lymphocyte ratio (NLR) and Red blood cells Distribution Width (RDW) have been found to be elevated in complicated pregnancy. However, data regarding the association of these haematological parameters with common carotid artery (CCA) intima-media thickness (IMT) in healthy pregnancy are scanty. Aim of this study was to evaluate possible changes in CCA-IMT during normal pregnancy and in the postpartum period, and to correlate these changes with NLR and RDW.</p> <p><strong>Study design: </strong>Between October 2019 and February 2020, a prospective study was carried out on 73 consecutive healthy pregnant women (32.8 ± 4.9 yrs/old). Women underwent obstetric assessment, complete blood cell counts with calculation of NLR and RDW, two-dimensional transthoracic echocardiography and carotid Doppler ultrasonography.</p> <p><strong>Results: </strong>During normal pregnancy, both NLR and RDW progressively increased (p < 0.0001); likewise, parameters of carotid dimensions also significantly increased (p < 0.0001). Hematological and morphological changes all decreased in postpartum period. By univariable logistic regression, the variables which showed the greatest independent association with CCA-IMT (defined as CCA-IMT ≥0.55 mm) were: age (HR 1.33, 95% CI 1.15-1.53, p < 0.0001), pre-pregnant BMI (HR 2.75, 95% CI 1.72-4.41, p < 0.0001), third trimester E/e' ratio (HR 1.64, 95% CI 1.34-2.02, p < 0.0001), and third trimester NLR (HR 3.00, 95% CI 1.64-5.50, p < 0.0001). Multivariable logistic regression analysis demonstrated that third trimester NLR was the only variable that retained statistical significance (HR 2.49, 95% CI 1.35-4.59, p = 0.003). An NLR ≥ 2 reached 83% of sensitivity and 99% of specificity in identifying a CCA-IMT ≥0.55 mm (AUC = 0.95). A strong linear correlation of both third trimester NLR and RDW with CCA-IMT was observed (r = 0.89 and 0.83, respectively).</p> <p><strong>Conclusions: </strong>Pregnancy is a state of chronic mild inflammation and the progressive increase in NLR and RDW during normal pregnancy is significantly associated with CCA intimal-medial thickening.</p> <p><strong>Keywords: </strong>common carotid artery intima-media thickness; healthy pregnancy; neutrophil to lymphocyte ratio.</p>

No association between developmental instability as a general measure of stress and 2D:4D digit ratios in a non-Western sample
<p>Objective: Random deviation from perfect symmetry of organisms is defined as fluctuating asymmetry. Fluctuating asymmetry is widely considered to be a marker of developmental instability, developmental noise and phenotypic quality at the population level. In this study, we investigated hypothesized relationship between 2D:4D digit ratios as a proxy measure of prenatal sex hormones and developmental instability levels in young adult humans Materials and Methods: In the study, seven bilateral traits were measured for fluctuating asymmetry, as well as second and fourth digit lengths on both hands of 185 individuals, 87 men (mean age: 22.42±3.37) and 97 women (mean age: 22.88±3.87). The second digit length was divided by the fourth digit length and the resulting value was used as the digit ratio (2D:4D). Composite fluctuating asymmetry was calculated using five bilateral traits displaying fluctuating asymmetry. Results: Only the right hand 2D:4D ratio is lower in men than in women. However, this difference disappears when the effect of digit lengths is controlled. Composite fluctuating asymmetry results reveal that men are more asymmetrical than women. There was no significant relationship between digit ratios and composite fluctuating asymmetry. Conclusion: In this study, the 2D:4D digit ratios appear to be influenced (at least in humans) by different digit lengths. This study also confirms previous studies that digit ratios as a proxy measure of exposure to either high testosterone or estrogen levels during early development does not appear to affect levels of developmental instability.</p>
