Despite being considered a relatively simple surgery compared with other metabolic choices, it has no negligible risk of postoperative complications. Gastric fistulas are one of the most feared complications and the most consensual explanation is the increased intraluminal pressure because of any cause of gastric emptying impairme...

Laiginhas, Rita; Guimarães, Marta; Cardoso, Pedro; Santos-Sousa, Hugo; Preto, John; Nora, Mário; Chibante, João; Falcão-Reis, Fernando; Falcão, ManuelINTRODUÇÃO: Estudos de investigação não clínica suportam a evidência da associação direta entre a obesidade e o aumento de stress oxidativo, diminuição da disponibilidade de óxido nítrico e consequente disfunção endotelial. Contudo, o impacto destas alterações in vivo é difícil de avaliar devido à inacessibilidade destes microvasos. Com este estudo pretendeu-se avaliar o impacto da obesidade ...

We included 25 studies for qualitative synthesis and 21 studies for quantitative synthesis. Relevant data was extracted, including proport...

Vinagre, João; Pinheiro, Jorge; Martinho, Olga; Reis, Rui Manuel; Preto, John; Soares, Paula; Lopes, José ManuelNeuroendocrine neoplasms (NENs) are the most common tumor of the appendix and have an excellent prognosis. Appendiceal tumors diagnosed between 1989 and 2019 were reviewed, and clinical data were collected from patient files. Part of the series was immuno-profiled for markers related to cell cycle proliferation and/or senescence-type, apoptotic, and metastatic potential. Appendix NENs were detected in 74 patien...

Diniz-Sousa, Florêncio; Veras, Lucas; Boppre, Giorjines; Sá-Couto, Pedro; Devezas, Vítor; Santos-Sousa, Hugo; Preto, John; Vilas-Boas, João PauloExercise has been suggested as a therapeutic approach to attenuate bone loss induced by bariatric surgery (BS), but its effectiveness remains unclear. Our aim was to determine if an exercise-training program could induce benefits on bone mass after BS. Eighty-four patients, submitted to gastric bypass or sleeve gastrectomy, were randomized to either exercise (EG) or control group (CG). One month post-BS, EG und...
