Misdiagnosed sessile serrated lesions (SSLs) are important precursors for interval colorectal cancers.

We investigated the usage of acetic acid (AA) solution for improving the detection of SSLs in the right colon in a randomized controlled trial.

A tandem observation of the right colon was performed in 412 consecutive patients. A first inspection was performed under white light high-definition endoscopy. In the AA group, a low concentration vinegar solution (AA 0.005%) irrigated by a water pump in the right colon was compared with a plain solution of normal saline (NS) in the diagnostic yield of SSLs during the second inspection. Secondary outcomes in overall polyp detection were measured.

Qualitative comparisons showed significant differences in the detection rates of all polyps except adenomas, with remarkable improvement in the demonstration of advanced (> 20mm), SSLs, and hyperplastic polyps during the second inspection of the right colon using the AA solution. Significant improvement was also noted in the AA group, as far as the mean number of polyps/patient detected, not only in SSLs (AA group 0.14 vs. NS group 0.01, P < 0.001), but also in all histological types and all size-categories in the right colon. Small (≤ 9mm) polyps were detected at a higher rate in the sigmoid colon expanding the effect of the method in the rest of the colon.

AA-assisted colonoscopy led to a significant increase in SSLs detection rate in the right colon in a safe, quick, and effective manner.

These compounds, due to lipophilic properties, accumulate in tissues of organisms, are transmitted through the food chain and ultimately threaten human health. The long-term use of pesticides led to soil and water pollution. Microbial degradation of organochlorine compounds is the most eco-friendly method of polluted soil recultivation. Effective degradation of lindane and DDT soil pollution under the influence of introduced destructive bacteria was shown in the laboratory conditions. The concentration of lindane in the soil decreased by 75% and of DDT-by 56% in 30 days. The red clover seedlings increased pesticides degradation in the soil by 20%. The destruction of pesticides in soil was more intense than in the mineral medium. The DGGE analysis of microorganism associations introduced in contaminated soil was possible to follow the survival of the introduced associations. The use of microorganisms-destructors of organochlorine compounds, and plants as well as the biodegradation potential of the soil is a promising direction in the recultivation of polluted soils.Breakthrough cancer pain (BTcP) is a variegated phenomenon, that often presents in different ways in each individual, and may change its presentation in the same individual during the course of disease. An appropriate assessment is fundamental for depicting the pattern of BTcP in individuals. This information is determinant for a personalised management of BTcP. The use of opioids as needed, is recommended for the management of BTcP. There are several options which should be chosen according to the individual pattern of BTcP. In general, a drug with a short onset and offset should be preferred. Although oral opioids may still have specific indications, fentanyl products have been found to be more rapid and effective, providing analgesia in 5-15 min. The most controversial point regards the opioid dose to be used. The presence of tolerance suggests using a dose that is proportional to the dose used for background analgesia. In contrast, regulatory studies have suggested using the minimal available dose to be titrated until the effective dose. Further large studies should definitely settle this never-ending question.The risks associated with negative peer relationships and low socioeconomic status (SES), and how they impact diurnal cortisol and the cortisol response to negative experiences, have never been studied together in early adolescents; this study aims to fill this gap in the literature. Saliva was collected from 95 early adolescents (Mage = 10.80, SD = 0.72) and daily diaries were completed 30 min after awakening, beginning of school, 15 min after first recess, 15 min after lunch, and at the end of the school day across four consecutive days. Hierarchical Linear Modelling was used to estimate the within- and between-person variances of diurnal cortisol and the cortisol response to stress in the context of SES and peer experiences. Cortisol secretion differed by gender and was predicted by SES and social status within the peer group. ML265 Low-SES early adolescents had higher morning cortisol. Girls who were from higher SES families had the steepest diurnal cortisol slope. Non-accepted early adolescents had low cortisol in response to both positive and negative social experiences. The findings from this study clarify the impact of both SES and peer relations on early adolescent psychophysiological development.Exposure to alcohol content in the media, especially in movies, is a demonstrated risk factor for adolescent alcohol use. This paper examines processes underlying this association and whether parenting mitigates such harms. A mediational model of parental restriction of mature media (W1), alcohol content exposure (W2), alcohol expectancies, peer norms (W3), and alcohol outcomes (W4) was tested using annual assessments from a study of adolescent drinking (N = 879; 52% female; 21% Non-White; 12% Hispanic). When restrictions are not in place, adolescents report greater exposure to alcohol content, leading to higher perceived peer drinking. Parental monitoring did not buffer the link between exposure and peer norms. Parental media restriction and perceptions about peers comprise mechanisms by which alcohol-saturated media influences youth drinking.Perceived economic stress and lower subjective social status (SSS) have adverse effects on parents' and adolescents' emotional well-being, but less is known about associations with academic adjustment among preadolescent youth. This study examined associations between SSS, perceived economic stress about needs and wants, and academic adjustment among preadolescents and early adolescents (n = 136, ages 8 to 14 years, 44% girls, 61% White) and their parents (n = 164, majority middle- to higher SES). Overall, youth who worried more about their family's economic needs had lower academic achievement and youth who reported lower SSS had lower academic motivation. No significant differences were observed in the strength of associations between parent and youth perceptions and academic outcomes for early adolescents versus preadolescents.
