Organochlorine pesticides contamination in agricultural soils of southern Iran.

Organochlorine pesticides contamination in agricultural soils of southern Iran. Chemosphere. 2020 Feb;240:124983 Authors: Kafaei R, Arfaeinia H, Savari A, Mahmoodi M, Rezaei M, Rayani M, Sorial GA, Fattahi N, Ramavandi B Abstract There is limited information about pesticide contamination in Iran's agricultural land, particularly in plains producing exportable fruits. The aim of this investigation was to evaluate the concentration of organochlorine pesticides (OCPs) including hexachlorocyclohexane (HCH), heptachlor, dichloro-diphenyl-trichloroethane (DDT), chlordane (CHL), and their isomers compounds in agricultural soils of southern Iran. A total of 28 topsoil samples were collected from agricultural lands of Dalaki and Shabankare areas, Bushehr, Iran. In Dalaki area, the mean value of ΣHCH (α, β, γ, δ), ΣDDT (o,p-DDE, o,p-DDD, o,p-DDT, p,p-DDE, p,p-DDD, p,p-DDT, and DDT), and ΣCHL (Trans-chlordane, Cis-chlordane, Heptachlor-exo-epoxide, and Heptachlor) was found to be 0.411 ng/g (dry weight, dw), 4.37 ng/g dw, and 2.04 ng/g dw, respectively. In Shabankare area the mean value of ΣHCH, ΣDDT, and ΣCHL was measured to be 1.38 ng/g dw, 11.99 ng/g dw, and 1.62 ng/g dw, respectively. The concentration trend of pesticides in both areas was as follows: DDT > CHL > HCH. Source identification indicated recent usage of HCH and DDT in the studied areas. Obtaining a cis-chlordane/tra...

BACKGROUND: In 2016, the American Society of Colon and Rectal Surgeons published a rectal cancer surgery checklist composed of the essential elements of preoperative, intraoperative, and postoperative care for patients undergoing rectal cancer surgery. OBJECTIVE: The purpose of this study was to assess whether compliance with preoperative checklist elements was associated with improved pathologic and 30-day postoperative outcomes after rectal cancer surgery. DESIGN: This was a retrospective cohort study. SETTINGS: The study involved North American hospitals contributing to the American College of Surgeons Nation...

CONCLUSIONS: The residual disease rate in patients treated surgically was higher than previously reported (43.2%). Incidence of recurrence in patients treated conservatively was low (4.4%). Areas of improvements have been identified in adherence to endoscopic follow-up, histopathological reporting, and potential overuse of radiological surveillance.

CONCLUSIONS: Resections that were approached laparoscopically were more likely to achieve oncologic success. Minimally invasive approaches did not lengthen operative times and provided benefits of reduced surgical site complications and decreased postoperative length of stay. Further studies are needed to clarify clinical outcomes and factors that influence the choice of approach. See Video Abstract at http://links.lww.com/DCR/B70.

CONCLUSIONS: The rates of total mesorectal excision performance and grade assignment are widely variable throughout the state of Michigan. Overall, grade assignment remains very low. This suggests an opportunity for quality improvement projects to increase total mesorectal excision performance and grading, involving both the surgeons and pathologists for effective implementation.
