ABSTRACT

Organoids are tissue cultures formed by culturing cells in three-dimensional environments that simulate the physiological or pathological conditions of the human body. The cultivation of organoids is used to study the temporal and spatial transformation of cells during the development of tissues or organs, to investigate changes in cellular functions and inter-communications caused by various risk factors, and to discover potential therapeutic targets. This article provided an overview of the cultivation and identification methods of alveolar organoids, as well as the research progress in their application to common respiratory diseases such as pulmonary fibrosis, chronic obstructive pulmonary disease, viral pneumonia, and so on. The limitations and future applications of alveolar organoids are also analyzed and discussed.

ABSTRACT

STUDY DESIGN: Prospective. OBJECTIVES: To evaluate detrusor leak point pressure (DLPP) of the incontinent ileovesicostomy in the supine and upright position. SETTING: California, USA. METHODS: Urodynamic assessment of patients, 6-36 months after ileovesicostomy, was performed in the supine position and then immediately repeated in the upright position in the patient's wheelchair. RESULTS: Upright and supine urodynamic evaluation was performed following the Good Urodynamic Practice Guidelines. Ten patients (seven male and three female) were evaluated. Etiology of neurogenic bladder (NGB) included seven patients with spinal cord injury and one patient each with multiple sclerosis, myelomeningocele and cerebral palsy. Mean DLLP in the supine position was 8.6 cm H2O (range 2-20); mean DLLP in the sitting position was 11.6 cm H2O (range 5-25). Mean change in DLPP from supine to sitting was 3.1 cm H2O (range 1-12). The difference in DLPP between supine and sitting is statistically significant (P=0.0429); however, this does not appear to be a clinically significant difference. CONCLUSION: Ileovesicostomy is a safe option for management of the NGB in a selected patient population. A small and clinically insignificant or no change in DLPP was documented in all ten patients. We demonstrated that DLPP remains low within an ileovesicostomy while in the sitting position.
