The skip phenomenon (SP) is a pattern where blood cultures are intermittently positive before final clearance. We report that one-third of patients with infective endocarditis experienced the SP. Patients with the SP experienced both a longer duration of bacteremia and hospital stay, with a higher 1-year mortality rate.

Intermittent negative blood cultures, known as the skip phenomenon (SP), frequently occur in patients with bacteremia (SAB), yet the clinical implications of SP in persistent SAB are not well understood. In this retrospective cohort study conducted at four university hospitals, SP was observed in 25 (11.3%) of 221 patients with persistent SAB.

This study elaborates the essence of distant lymph node metastasis and skip metastasis of esophageal cancer according to the membrane anatomy theory. Lymph distant metastasis of esophageal cancer is essentially the phenomenon of cancer cells shedding from the primary focus of esophageal cancer and transferring along the direction of lymphatic drainage to the root of the esophageal mesentery. Because the metastasis is relatively distant, it is called distant metastasis.

It has long been known that the chiasmata are not independently distributed in most organisms, a phenomenon known as chiasma interference. In this paper, I suggest a model of chiasma interference that generalizes the Poisson model, the counting model, the Poisson-skip model, and the two-pathway counting model into a single framework, and use it to derive infinite series expressions for the sterility and recombination pattern probabilities in inversion homo- and heterokaryotypes, and a closed-form expression for the special case of the two-pathway counting model in homokaryotypes. I then use these expressions to perform maximum likelihood parameter estimations for recombination and tetrad data from various species.
