Glucosamine and chondroitin for osteoarthritis? 总被引:1,自引:0,他引:1
McAlindon T 《Bulletin on the rheumatic diseases》2001,50(7):1-4
The current body of evidence currently supports modest efficacy for glucosamine and chondroitin in the treatment of OA symptoms. The products are safe and could play a valuable role in the management of this disorder. Nevertheless, further independent studies are needed to confirm these findings and to determine the clinical applicability of these compounds. Physicians need to become involved in these treatment decisions but are confused by wide variability in the formulation and purity of the numerous preparations available to consumers. The notion that glucosamine and chondroitin might have disease-modifying effects in OA is highly appealing and supported by preliminary data. Research is needed to confirm these findings and to evaluate the impact of glucosamine and chondroitin on all aspects of OA progression. 相似文献

Purpose of Review
Esophageal adenocarcinoma bears one of the fastest rising incidence of any cancers and generally arises in the setting of gastroesophageal reflux and Barrett’s esophagus. However, early detection of neoplasia can be challenging since most patients are asymptomatic until they progress to more advanced and less curable stages, and early dysplastic lesions can be small, multifocal, and difficult to detect. Clearly, new imaging tools are needed in light of sampling error associated with random biopsies, the current standard of practice.Recent Findings
Advances in endoscopic imaging including virtual chromoendoscopy, confocal laser endomicroscopy, and subsurface imaging with optical coherence tomography have ushered in a new era for detecting subtle neoplastic lesions. Moreover, in light of esophagus-sparing treatments for neoplastic lesions, such tools are likely to guide ablation and follow-up management.Summary
While there is no ideal single imaging modality to facilitate improved detection, staging, ablation, and follow-up of patients with dysplastic Barrett’s esophagus, new advances in available technology, the potential for multimodal imaging, and the use of computer-aided diagnosis and biomarkers all hold great promise for improving detection and treatment.6.

The authors identified individual randomized controlled trials from previous meta-analyses and additional searches, and then performed meta-analyses on cardiovascular disease outcomes and all-cause mortality. The authors assessed publications from 2012, both before and including the U.S. Preventive Service Task Force review. Their systematic reviews and meta-analyses showed generally moderate- or low-quality evidence for preventive benefits (folic acid for total cardiovascular disease, folic acid and B-vitamins for stroke), no effect (multivitamins, vitamins C, D, β-carotene, calcium, and selenium), or increased risk (antioxidant mixtures and niacin [with a statin] for all-cause mortality). Conclusive evidence for the benefit of any supplement across all dietary backgrounds (including deficiency and sufficiency) was not demonstrated; therefore, any benefits seen must be balanced against possible risks. 相似文献

This retrospective study was designed to evaluate the safety and efficacy of long-term lamivudine therapy in Korean patients with chronic hepatitis B virus (HBV) with or without cirrhosis. Study patients were men and women who had received lamivudine 100 mg/day p.o. for 52 wk for treatment of biopsy-proven chronic HBV; 11/29 patients had cirrhosis. Patient eligibility requirements included having a diagnosis of chronic HBV, being positive for HBV by polymerase chain reaction, at least 18 yr of age, and positive for HBsAg, and having abnormally elevated ALT levels. Patients were evaluated for changes in HBV DNA and ALT concentrations, rates at which HBeAg was converted to negative, development of lamivudine resistance, and differences in the drug's effectiveness between patients with and without cirrhosis. Responses of serum HBV DNA and ALT were categorized into three groups according to degree of response to lamivudine treatment: continuous, unstable, and no response.
Twenty-nine patients were evaluated in this retrospective analysis. Therapy with lamivudine suppressed serum HBV DNA to undetectable levels in 97% of patients within 12 wk and remained undetectable in 83% of patients after 52 wk. Differences in responses of HBV DNA and ALT to lamivudine therapy in HBeAg-positive and -negative patients and in the development of drug resistance between patients with and without cirrhosis were negligible. Pretreatment HBV DNA and ALT levels had no effect on the efficacy of lamivudine ( p = 0.9116 ).
No serious adverse events were reported. 相似文献

The rapid increase in the incidence of oesophageal adenocarcinoma, particularly among white males, seems to be a true increase occurring in many parts of the industrialised world during the last few decades. Some main risk factors have been established: i.e. Barrett's oesophagus, gastrooesophageal reflux, high body mass, male sex, tobacco smoking, and high dietary intake of fruit and vegetables. Several other potential risk factors have been studied for which the evidence is less clear, including medications that relax the lower oesophageal sphincter or diets high in fat or low in nutrients from plant foods. Other factors have been found to be possibly inversely linked with the risk of oesophageal adenocarcinoma, including infection with Helicobacter pylori and anti-inflammatory drugs (such as aspirin and other non-steroidal anti-inflammatory drugs, including cyclo-oxygenase inhibitors). The methodological problem of 'confounding by indication' makes it difficult to interpret the results of anti-inflammatory drugs, and currently such medication cannot be recommended for the prevention of oesophageal adenocarcinoma. Similarly, since there is no strong evidence of a preventive effect of medical or surgical antireflux therapy with regard to risk of oesophageal adenocarcinoma, such therapy cannot be recommended in the prevention of this cancer. Although some of the known risk factors might contribute to the increasing incidence of oesophageal adenocarcinoma, the explanation that can entirely explain this striking trend remains to be identified. Oesophageal adenocarcinoma is a highly deadly cancer, but the overall prognosis and the prognosis after oesophageal cancer surgery has improved during recent years. 相似文献

We reviewed interventions that affect maternal and child undernutrition and nutrition-related outcomes. These interventions included promotion of breastfeeding; strategies to promote complementary feeding, with or without provision of food supplements; micronutrient interventions; general supportive strategies to improve family and community nutrition; and reduction of disease burden (promotion of handwashing and strategies to reduce the burden of malaria in pregnancy). We showed that although strategies for breastfeeding promotion have a large effect on survival, their effect on stunting is small. In populations with sufficient food, education about complementary feeding increased height-for-age Z score by 0.25 (95% CI 0.01-0.49), whereas provision of food supplements (with or without education) in populations with insufficient food increased the height-for-age Z score by 0.41 (0.05-0.76). Management of severe acute malnutrition according to WHO guidelines reduced the case-fatality rate by 55% (risk ratio 0.45, 0.32-0.62), and recent studies suggest that newer commodities, such as ready-to-use therapeutic foods, can be used to manage severe acute malnutrition in community settings. Effective micronutrient interventions for pregnant women included supplementation with iron folate (which increased haemoglobin at term by 12 g/L, 2.93-21.07) and micronutrients (which reduced the risk of low birthweight at term by 16% (relative risk 0.84, 0.74-0.95). Recommended micronutrient interventions for children included strategies for supplementation of vitamin A (in the neonatal period and late infancy), preventive zinc supplements, iron supplements for children in areas where malaria is not endemic, and universal promotion of iodised salt. We used a cohort model to assess the potential effect of these interventions on mothers and children in the 36 countries that have 90% of children with stunted linear growth. The model showed that existing interventions that were designed to improve nutrition and prevent related disease could reduce stunting at 36 months by 36%; mortality between birth and 36 months by about 25%; and disability-adjusted life-years associated with stunting, severe wasting, intrauterine growth restriction, and micronutrient deficiencies by about 25%. To eliminate stunting in the longer term, these interventions should be supplemented by improvements in the underlying determinants of undernutrition, such as poverty, poor education, disease burden, and lack of women's empowerment. 相似文献

Cholangiocarcinomas are categorized as intrahepatic cholangio- carcinoma (iCCA), perihilar cholangiocarcinoma (pCCA), and dis- tal cholangiocarcinoma (dCCA) [1] . iCCA and pCCA are the second most common primary hepatobiliary malignant neoplasms [ 1 , 2 ]. Most patients with iCCA and pCCA have asymptomatic clinical course, highly aggressive nature and dismal prognosis [3] . Com- plete surgical resection offers the best possibility of long-term sur- vival but only a minority of patients are amenable to R0 resec- tion [4] . Tumor involvement of segmental bilateral intrahepatic bile duct, inadequate remnant liver volume or hepatic functional reserve due to underlying chronic liver disease, are key factors limiting the resectability of iCCA and pCCA. Liver transplantation (LT) provides an option for patients with unresectable iCCA and pCCA [4] . 相似文献

High blood pressure is among the most prevalent chronic disease in adults that impacts on the quality of life of patients, which are often subjected to physical rehabilitation. Chinese medicine intervention in patients with hypertension presents promising albeit inconclu-sive results, mostly due to methodological issues. This paper discusses asserted and neglected issues linking evidence-based and Chinese medicines as related to systemic arterial hypertension, as well as their impact on the physical rehabilitation of those patients. On the one hand, natural history of hypertension, pulse palpa-tion, and herbal therapy are among the asserted issues because of the scientific evidence collected about them, either in favor or against its integration to the current medical practice. On the other hand, anatomical varia-tions of vessels and comparative physiology are among the most commonly neglected issues because previous researches on integrative medicine ignored the pos-sible effects of these issues as related to the study's outcome. The asserted issues highlighted in this paperstimulate the increasing use of Chinese medicine for health care and the continuity of research on integra-tive medicine in the cardiovascular field for rehabilita-tion. The neglected issues poses additional challenges that must not be overlooked in future research on this topic so that the integration of both traditional and cur-rent knowledge may be of benefit to the population with cardiovascular disease. 相似文献

BACKGROUND: Hepatocellular carcinoma (HCC) is a common disease with high mortality and serious effect on the life quality of patients. Operation is still the most effective treatment. Currently, in China, patients with HCC are often complicated by hepatitis B related liver cirrhosis and secondary hypersplenism. This study was undertaken to evaluate the effect and indications of synchronous hepatectomy and splenectomy for HCC patients with hypersplenism. METHODS: The clinical records and treating processes of 24 patients with HCC and hypersplenism during the period of January 1991 to July 2004 were analyzed retrospectively. RESULTS: Sixteen patients underwent hepatectomy and splenectomy, including extensive devascularizasion around the cardia (9 patients). Seven patients were treated with microwave ablation and splenectomy plus extensive esophagogastric devascularization. One patient underwent hepatectomy combined with microwave ablation and splenectomy plus extensive esophagogastric devascularization. There were no deaths during the operation. During the first week after operation, the symptoms of hypersplenism disappeared and the platelet (Plt) and white blood cell (WBC) counts were significantly elevated (Plt: 247×109/L vs. 45.9×109/L, WBC: 13.0×109/L vs.3.3×109/L,P<0.01). CONCLUSIONS: Synchronous splenectomy can increase the safety of hepatectomy in selected patients with HCC and secondary hypersplenism by reducing bleeding complications. Splenectomy enhances patients' immunity against tumor in a long period as well. 相似文献
