The use of radio-opaque markers and abdominal X-ray is the standard method for determining colonic transit time(CTT). However, when there are deviations in the intake of these markers by participants in clinical trials it is desirable to improve observations by introducingcorrections, where possible. To date, there is no standard procedure to adjust for such deviations. This report proposes a series of alternatives based on possible scenarios for deviations from the intended intake of radio-opaque markers. The proposed method to correct for missed or delayed consumption of radioopaque markers can help to increase the accuracy of the CTT measurements in clinical trials.

Brugada syndrome is an inherited disease associated with an increased risk of lethal ventricular arrhythmias. Such arrhythmias stem from innate disruptions in cardiac electrophysiology. Typically, such arrhythmias occur in the third or fourth decade of life. However, Brugada syndrome may also affect geriatric patients. In this paper, we focus on the ageing patientwithBrugada syndrome, and specifically, on the interaction between Brugada syndrome and the more usually acquired clinical problems that may occur with increasing age, such as the use of cardiovascular and non-cardiovascular drugs, or the need for surgery. Such common conditionsmay also disrupt cardiac electrophysiology, thereby conferring added risk for Brugada syndrome patients. We present some considerations and recommendations that may serve as guidance to address these complexities.

Several stories of various pioneers establishing acupuncture and Chinese medicine （ACM） practices in the United States （U.S.） have been documented. However, the establishment of schools for ACM signaled the establishment of ACM as an established profession in the U.S. One of the first persons who wanted to set-up a school for Chinese medicine in the U.S. was Dr. Tom Foo Yuen （谭富园, August 7, 1858 - July 10, 1947） during the late 1800s in Los Angeles （LA）, California. However, it was not until 1969 or 1970 that the first informal ACM school was actually established in the U.S. This school was called the Institute for Taoist Study, and was located in LA. However, this school was not registered with the local government and Dr. Gim Shek Ju was the sole teacher at that time.

BACKGROUND： Chinese and contemporary Western medical practices evolved on different cultures and historical contexts and, therefore, their medical knowledge represents this cultural divergence. Computerization of traditional Chinese medicine （TCM） is being used to promote the integrative medicine to manage, process and integrate the knowledge related to TCM anatomy, physiology, semiology, pathophysiology, and therapy. METHODS： We proposed the development of the SuiteTCM software, a collection of integrated computational models mainly derived from epidemiology and statistical sciences for computerization of Chinese medicine scientific research and clinical practice in all levels of prevention. The software includes components for data management （DataTCM）, simulation of cases （SimTCM）, analyses and validation of datasets （SciTCM）, clinical examination and pattern differentiation （DiagTCM, TongueTCM, and PulseTCM）, intervention selection （AcuTCM, HerbsTCM, and DietTCM）, management of medical records （ProntTCM）, epidemiologic investigation of sampled data （ResearchTCM）, and medical education, training, and assessment （StudentTCM）. DISCUSSION： The SuiteTCM project is expected to contribute to the ongoing development of integrative medicine and the applicability of TCM in worldwide scientific research and health care. The SuiteTCM 1.0 runs on Windows XP or later and is freely available for download as an executable application.
