Using convolutional neural networks to count parrot nest-entrances on photographs from the largest known colony of Psittaciformes.

Counting animal populations is fundamental to understand ecological processes. Counts make it possible to estimate the size of an animal population at specific points in time, which is essential information for understanding demographic change. However, in the case of large populations, counts are time-consuming, particularly if carried out manually.

Translumenal endoscopic drainage of abdominal abscess due to early migration of adjustable gastric band.

We describe the case of early band migration that developed into intraabdominal infection treated by natural orifice translumenal endoscopic surgery. A 40-year-old man was seen 4 years after gastric band placement. He complained of epigastric pain and fever.

Wound infection rates in clean surgery: a potentially misleading risk classification.

Objectives: To evaluate the incidence of wound infection in inguinal hernioplasties, incisional hernioplasties, splenectomies, and splenectomies performed in patients with hepatosplenic schistosomiasis, and to examine the relationship of surgical wound infection to antibiotic use, patient age, length of stay in the hospital prior to surgery, and the duration of the operation.

Design: Retrospective surveillance study.

Results: One thousand five hundred forty-two clean operations were analyzed.
