Objective
Helicobacter pyloriinfection is mostly a
family-based infectious disease. To facilitate its prevention and
management, a national consensus meeting was held to review current
evidence and propose strategies for population-wide and
family-basedH. pyloriinfection control
and management to reduce the related disease burden.
Methods
Fifty-seven experts from 41 major universities and institutions in
20 provinces/regions of mainland China were invited to review evidence
and modify statements using Delphi process and grading of
recommendations assessment, development and evaluation system. The
consensus level was defined as ≥80% for agreement on the proposed
statements.
Results
Experts discussed and modified the original 23 statements on
family-basedH. pyloriinfection
transmission, control and management, and reached consensus on 16
statements. The final report consists of three parts: (1)H.
pyloriinfection and transmission among family members,
(2) prevention and management ofH.
pyloriinfection in children and elderly people within
households, and (3) strategies for prevention and management
ofH. pyloriinfection for family members.
In addition to the ‘test-and-treat’ and ‘screen-and-treat’ strategies,
this consensus also introduced a novel third
‘family-basedH. pyloriinfection control
and management’ strategy to prevent its intrafamilial transmission and
development of related diseases.
Conclusion
H. pyloriis transmissible from person to
person, and among family members. A family-basedH.
pyloriprevention and eradication strategy would be a
suitable approach to prevent its intra-familial transmission and related
diseases. The notion and practice would be beneficial not only for
Chinese residents but also valuable as a reference for other highly
infected areas.
Renal colic is a common condition seen in the emergency department (ED). Our recent study showed that measures of electrical conductance may be used as supplementary diagnostic methods for patients with acute renal colic. Here, we describe the case of a 30-year-old male subject with a left ureteral calculus who presented with frequency and normal-looking urine. He had already visited the outpatient department, but in vain. Normal urinalysis and nonobstructive urogram were reported at that time. Two days later, he was admitted to the ED because of abdominal pain in the left lower quadrant. The urinalysis did not detect red blood cells. Ultrasonography did not indicate hydronephrosis. The meridian electrical conductance and index of sympathovagal balance were found to be abnormal. High level of electrical conductance on the left bladder meridian was found. An unenhanced helical computed tomography was scheduled to reveal a left ureterovesical stone. Ureteroscopic intervention was later uneventfully performed, and the patient's pain was relieved. The follow-up measurements showed that the meridian parameters had returned to normal one month after treatment. This case suggests that bladder meridian electrical conductance might be used as a supplemental method for ureteral calculus diagnosis.
The initial iterative control signal is often adopted a zero or a certain value in the conventional iterative learning control (ILC) system, and an ILC process needs to renew again as long as the desired trajectory is changed. In this paper, the NURBS (Non-Uniform Rational B-Splines) model is used for describing all trajectory primitives and the desired trajectory. It is studied that the problem of the initial iterative control signal is extracted in ILC, which presents a method of extracting the initial iterative control signal based on the trajectory primitive optimal matching and combining algorithm. Firstly, the definition of the similarity index between the two different spacial trajectories is introduced. Secondly, an optimal matching and combining algorithm is designed under a certain similarity index, which is used to find two or more combined primitive sequences with space patterns similar to the desired trajectory. Thirdly, the initial iterative control signals of the desired trajectory are extracted by using the control information of the combined primitive sequences. Finally, the simulation is carried out to demonstrate the effectiveness of the present method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
