The Practice Guidelines for Primary Care of Acute Abdomen 2015 have been prepared as the first evidence-based guidelines for the management of acute abdomen. We hope that these guidelines contribute to clinical practice and improve the primary care and prognosis of patients with acute abdomen.
Since acute abdomen requires accurate diagnosis and treatment within a particular time limit to prevent mortality, the Japanese Society for Abdominal Emergency Medicine, in collaboration with four other medical societies, launched the Practice Guidelines for Primary Care of Acute Abdomen that were the first English guidelines in the world for the management of acute abdomen. Here we provide the highlights of these guidelines (all clinical questions and recommendations were shown in supplementary information). A systematic and comprehensive evaluation of the evidence for epidemiology, diagnosis, differential diagnosis, and primary treatment for acute abdomen was performed to develop the Practice Guidelines for Primary Care of Acute Abdomen 2015. Because many types of pathophysiological events underlie acute abdomen, these guidelines cover the primary care of adult patients with nontraumatic acute abdomen. A total of 108 questions based on nine subject areas were used to compile 113 recommendations. The subject areas included definition, epidemiology, history taking, physical examination, laboratory test, imaging studies, differential diagnosis, initial treatment, and education. Japanese medical circumstances were considered for grading the recommendations to assure useful information. The two-step methods for the initial management of acute abdomen were proposed. Early use of transfusion and analgesia, particularly intravenous acetaminophen, were recommended. The Practice Guidelines for Primary Care of Acute Abdomen 2015 have been prepared as the first evidence-based guidelines for the management of acute abdomen. We hope that these guidelines contribute to clinical practice and improve the primary care and prognosis of patients with acute abdomen.
In connection with the chemical structure of coumarin 1 (a mixture of acetylangeloylkhellactone and acetyltigloylkhellactone), a compound isolated from Peucedanum japonicum THUNB., we synthesized eight coumarin compounds (3-10) and performed pharmacological studies on these nine compounds, as well as on another coumarin, praeruptorin A (= Pd-Ia) (2), a compound isolated from Peucedanum praeruptorum DUNN. We studied the effects of compounds 1-5 on isolated smooth muscle and of compounds 1-10 on the cardiovascular system. These compounds showed dose-related antagonistic effects on histamine- and Ca(2+)-induced contractions in smooth muscle and the potencies were in the order 2 greater than 1 greater than seselin (3) greater than xanthyletin (4) = 2.2.10-trimethyl-2H,8H-benzo[1,2-b: 3,4-b']dipyran-8-one (5). All the compounds except 7-geranyloxy-4-methylcoumarin (10) produced a dose-related increase in vertebral, carotid and femoral blood flow. Compounds 1, 5, and 4-methyl-7-(3-methyl-2-butenyloxy)coumarin (8) caused an increase in blood pressure, but 3 and 4 caused a slight decrease. Compounds 2, 3, 4, 5, and 8 increased heart rate. Jatamansinone (6) and jatamansinol (7) caused only slight changes in blood pressure. All the compounds except 10 increased heart rate. Compound 1 also increased blood flow in the cerebral cortex. Thus, compound 1 was confirmed to have an inhibitory effect on contraction in isolated smooth muscle and an action increasing arterial blood flow. Among the compounds tested in this study, 3, as well as 6 and 7 synthesized on the basis of 3, showed actions similar to those of Ca2+ blockers and some compounds had papaverine-like activities.(ABSTRACT TRUNCATED AT 250 WORDS)
Background We reported in a previous study that the initial effects of left ventricular (LV) repair (LVR) for LV aneurysm were not long lasting. Angiotensin-converting enzyme inhibitor (ACE-I) is known to attenuate remodeling after myocardial infarction, and could be effective after LVR. Methods and Results Left ventricular aneurysms were developed in rats after left anterior descending artery ligation. Rats were divided into 3 groups: sham operation with ACE-I (lisinopril 10 mg/kg/d) (n=10; group A), LVR (by plicating the LV aneurysm) with placebo (n=8; group R), and LVR with ACE-I (n=10; group RA). LV function was evaluated by echocardiography and catheterization. Oxidative stress in the myocardium was estimated by immunohistochemistry for 8-hydroxy-2′-deoxyguanosine. One week after LVR, LV end-diastolic area was smaller and fractional area change was better in the 2 LVR groups. Four weeks after LVR, LV end-diastolic area, and fractional area change deteriorated in group R but not so much in group RA; E-max was higher in group RA (0.79±0.20 mm Hg/mL) than in groups A (0.25±0.03 mm Hg/mL; P <0.01) and group R (0.27±0.03 mm Hg/mL; P <0.01). Oxidative stress was much lower in the 2 ACE-I groups. Conclusions LVR improved LV size and systolic function only in the early phase. Adjuvant use of ACE-I was useful for preventing redilation and maintaining LV systolic function, was associated with suppressed oxidative stress, and may make LVR a more effective surgical procedure for LV aneurysm.
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.
