First molecular identification of the zoonotic parasite Anisakis pegreffii (Nematoda: Anisakidae) in a paraffin-embedded granuloma taken from a case of human intestinal anisakiasis in Italy

<p>Abstract</p> <p>Background</p> <p>Anisakiasis is an important fish-borne zoonosis provoked by larval stages of nematodes belonging to the genus <it>Anisakis</it>. The detection and identification of human infections is difficult. This is due to: a) the low specificity of the clinical features and symptomatology related to human infections; b) the paucity of diagnostic features of larvae found in granulomatous lesions characteristic of "invasive anisakiasis"; and c) the lack morphological characters diagnostic at the specific level when larvae of <it>Anisakis </it>are detected. Thus, molecular-based diagnostic approaches are warranted.</p> <p>Method</p> <p>We have developed a PCR method that amplifies the DNA of <it>Anisakis </it>spp. in fixed paraffin-embedded tissues. This method was applied to a granuloma removed from a human case of intestinal anisakiasis in Italy. Specific primers of the mtDNA <it>cox2 </it>gene were used and sequence analysis was performed according to the procedures already established for species of <it>Anisakis</it>.</p> <p>Results</p> <p>The sequence obtained (629 bp) was compared with those of the other species of <it>Anisakis </it>which have so far been genetically characterized and with sequences obtained from larval stages of <it>Anisakis </it>collected from the Mediterranean fish <it>Engraulis encrasicolus</it>. This enabled the genetic identification of the larva in the human tissue as <it>A. pegreffii</it>. This is the first instance of human intestinal anisakiasis diagnosed using PCR of DNA purified from a fixed eosinophilic granuloma embedded in paraffin.</p> <p>Conclusion</p> <p>The case of human anisakiasis presented reinforces the pathological significance of the species <it>A. pegreffii </it>to humans. The molecular/genetic methodological approach based on mtDNA <it>cox2 </it>sequence analysis, described here, can allow easy and rapid identification of <it>Anisakis </it>spp. in formalin-fixed and paraffin embedded tissues removed from cases of either gastric or intestinal human anisakiasis.</p

Emoporn

Porn is so safe; everything is inscribed in a master plan. Like a drug designed to consume entertainment and to be back to work in time, pornography allows you to be at ease in the corner of your world. Through masturbatory micro-rituals, it reaffirms all Western societies values. Back when Pluto was a planet, pushed by the advent of digital technology, a lightning ripped through the grey sky of this boredom valley. In the historical period between the nineties and the two-thousands, pushed by the possibilities of digital communication, a new body front emerged as theoretical and activist battleground, deconstructing the dogmatic anti-sexwork positions of historical feminism and LGBT-identities. “Porn Studies” came out as an open, multidisciplinary field, mixing Queer Theory, Gender Studies, Media Studies, Cinema History and Performance Art. One of the main goals stands in the use of pornography as text, in which to read and to deconstruct identity boundaries where either heteronormative or LGBT-gentrifying politics produce a flat market space. The application of D.I.Y.-ethics to “Porn Studies” moved the thought to a political and &nbsp; &nbsp; activist level through the practices of self- representation and cultural individualization

ERAS program adherence-institutionalization, major morbidity and anastomotic leakage after elective colorectal surgery: the iCral2 multicenter prospective study

Background Enhanced recovery after surgery (ERAS) programs influence morbidity rates and length of stay after colorectal surgery (CRS), and may also impact major complications and anastomotic leakage rates. A prospective multicenter observational study to investigate the interactions between ERAS program adherence and early outcomes after elective CRS was carried out. Methods Prospective enrolment of patients submitted to elective CRS with anastomosis in 18 months. Adherence to 21 items of ERAS program was measured upon explicit criteria in every case. After univariate analysis, independent predictors of primary endpoints [major morbidity (MM) and anastomotic leakage (AL) rates] were identified through logistic regression analyses including all significant variables, presenting odds ratios (OR). Results Institutional ERAS protocol was declared by 27 out of 38 (71.0%) participating centers. Median overall adherence to ERAS program items was 71.4%. Among 3830 patients included in the study, MM and AL rates were 4.7% and 4.2%, respectively. MM rates were independently influenced by intra- and/or postoperative blood transfusions (OR 7.79, 95% CI 5.46-11.10; p &lt; 0.0001) and standard anesthesia protocol (OR 0.68, 95% CI 0.48-0.96; p = 0.028). AL rates were independently influenced by male gender (OR 1.48, 95% CI 1.06-2.07; p = 0.021), intra- and/or postoperative blood transfusions (OR 4.29, 95% CI 2.93-6.50; p &lt; 0.0001) and non-standard resections (OR 1.49, 95% CI 1.01-2.22; p = 0.049). Conclusions This study disclosed wide room for improvement in compliance to several ERAS program items. It failed to detect any significant association between institutionalization and/or adherence rates to ERAS program with primary endpoints. These outcomes were independently influenced by gender, intra- and postoperative blood transfusions, non-standard resections, and standard anesthesia protocol
