Developing-world shark fisheries are typically not assessed or actively managed for sustainability; one fundamental obstacle is the lack of species and size-composition catch data. We tested and implemented a new and potentially widely applicable approach for collecting these data: mandatory submission of low-value secondary fins (anal fins) from landed sharks by fishers and use of the fins to reconstruct catch species and size. Visual and low-cost genetic identification were used to determine species composition, and linear regression was applied to total length and anal fin base length for catch-size reconstruction.

Department of Surgery, Aarhus University Hospital, Aarhus, Denmark.

Background: Watchful waiting in patients with rectal cancer with complete clinical response after chemoradiation therapy has gained increased popularity to avoid morbidity and mortality associated with surgery. Irradiation of the pelvis causes bowel dysfunction, but the effect on anorectal sensory function remains obscure in this patient category.

Objective: The aim of this study was to characterize the sensory pathways of the gut-brain axis in patients with rectal cancer treated solely with chemoradiation therapy (nonconventional regime/dose) compared with healthy volunteers. Read More

Background: Sphincter-preserving operations have been increasingly used for treating anal fistula. However, their success rates remain modest in complex anal fistulas.

Objective: This study aimed to report outcomes of video-assisted ligation of intersphincteric fistula tract (a procedure combining video-assisted anal fistula treatment and ligation of intersphincteric fistula tract) for treating complex anal fistulas and to compare its results with conventional ligation of intersphincteric fistula tract.

Background: People living with HIV have high rates of anal human papillomavirus infection and anal precancer/cancer.

Objective: This study aims to: 1) determine human papillomavirus subtype distribution among people living with HIV with anal high-grade squamous intraepithelial lesions; 2) compare the clinicopathological characteristics of patients with anal high-grade squamous intraepithelial lesions by human papillomavirus 16 status; and 3) investigate high-risk human papillomavirus negative anal high-grade squamous intraepithelial lesion cases.

Design: In this retrospective study, 700 people living with HIV who have biopsy-proven anal high-grade squamous intraepithelial lesions were reviewed for demographics, cytological diagnoses, and human papillomavirus testing results for human papillomavirus 16, 18, and 12 other high-risk types.

Background: Ligation of the intersphincteric fistula tract is a sphincter-preserving technique for the treatment of anal fistulas. The BioLIFT modification involves the placement of a biologic mesh in the intersphincteric plane. Advocates of this modification state improved healing rates, however evidence for this is lacking, and this approach costs significantly more. Read More
