We suggest that available medical information and digital/electronic methods could be used to manage this major healthcare problem for individual patients in real time. Methods: We searched the available digital applications and three literature databases using the medical subject heading terms, adverse drug reaction reporting systems or management, filtered by clinical trial or systemic reviews, to detect publications with data about ADR identification and management approaches. We reviewed the reports that had abstract or summary data or proposed or implemented methods or systems with potential to identify or manage ADRs in clinical settings. Results: The vast majority of the 481 reports used retrospectively collected data for groups of patients or were limited to surveying one population group or class of medication. The reports showed potential and definite associations of ADRs for specific drugs and problems, mostly, but not exclusively, for patients in hospitals and nursing homes. No reports described complete methods to collect comprehensive data on ADRs for individual patients in a healthcare system. The digital applications have ADR information, but all are too cumbersome or incomplete for use in active clinical settings. Several studies suggested that providing information about potential ADRs to clinicians can reduce these problems. Conclusion and Relevance: Although investigators and government agencies agree with the need, there is no comprehensive ADR management program in current use. Informing the patient’s healthcare practitioners of potential ADRs at the point of service has the potential for reduction of these complications, which should improve healthcare and reduce unneeded costs.展开更多

[ Method ] The mother liquid of alga, which was separated from the eutrophic water, were put into the solutions of Hg^2+ and Cr(Ⅵ) with different concentrations and their mixture solution, respectively. And the toxicity effect of Hg^2+ and Cr(Ⅵ) on the growth and propagation of alga in eutrophic water was observed. [ Result] The alga in eutrophic water performed rather sensitive to Cr(Ⅵ) and when its concentration was over 1 mg/L, threre was obvious effect on alga growth. The alga was not very sensitive to Hg^2+ when its concentration was lower, but its toxicity became stronger and stronger when its concentration increased to some extent and the toxicity effect of Cr(Ⅵ) on alga growth was just on the contrary. When the ion concentration was lower than 10 mg/L, the toxicity of Hg^2+ on alga was lower than that of Cr(Ⅵ). When the concentration was over 10 mg/L, the toxicity of Hg^2+ exceeded that of Cr(Ⅵ). The toxicity of ion mixture solution of Hg^2+ and Cr(Ⅵ) had synergism inhibition on alga, which could be performed only when the concentration was over 4 mg/L. [ Conclusion] The toxicity of heavy metal on alga not only related to the alga cell, but also related to the concentration of heavy metal ion.展开更多

However, this procedure sometimes induces excessive intraoperative blood loss and requires perioperative allogeneic blood transfusion. There are lasting discussions and controversies about whether intraoperative blood loss or perioperative blood transfusion has adverse effects on the prognosis in patients with gastric cancer. We reviewed laboratory and clinical evidence of these associations in patients with gastric cancer. A large amount of clinical evidence supports the correlation between excessive intraoperative blood loss and adverse effects on the prognosis. The laboratory evidence revealed three possible causes of such adverse effects: anti-tumor immunosuppression, unfavorable postoperative conditions, and peritoneal recurrence by spillage of cancer cells into the pelvis. Several systematic reviews and meta-analyses have suggested the adverse effects of perioperative blood transfusions on prognostic parameters such as all-cause mortality, recurrence, and postoperative complications. There are two possible causes of adverse effects of blood transfusions on the prognosis: Anti-tumor immunosuppression and patient-related confounding factors (e.g., preoperative anemia). These factors are associated with a worse prognosis and higher requirement for perioperative blood transfusions. Surgeons should make efforts to minimize intraoperative blood loss and transfusions during gastric cancer surgery to improve patients’ prognosis.展开更多

They are generally well-tolerated by patients and safe to use. To date, a significant number of patients have been treated with NAs. Safety data has accumulated over the years. The aim of this article is to review and update the adverse effects of oral NAs. NAs can cause class adverse effects(i.e., myopathy, neuropathy, lactic acidosis) and dissimilar adverse effects. All NAs carry a "Black Box" warning because of the potential risk for mitochondrial dysfunction. However, these adverse effects are rarely reported. The majority of cases are associated with lamivudine and telbivudine. Adefovir can lead to dose- and time-dependent nephrotoxicity, even at low doses. Tenofovir has significant renal and bone toxicity in patients with human immunodeficiency virus(HIV) infection. However, bone and renal toxicity in patients with CHB are not as prominent as in HIV infection. Entecavir and lamivudine are not generally associated with renal adverse events. Entecavir has been claimed to increase the risk of lactic acidosis in decompensated liver disease and high Model for End-Stage Liver Disease scores. However, current studies reported that entecavir could be safely used in decompensated cirrhosis. An increase in fetal adverse events has not been reported with lamivudine, telbivudine and tenofovir use in pregnant women, while there is no adequate data regarding entecavir and adefovir. Further long-term experience is required to highlight the adverse effects of NAs, especially in special patient populations, including pregnant women, elderly and patients with renal impairment.展开更多

The lyophilized cell extract injected intraperitoneally at 1 and 2 LD50 (15.8 and 31.6 mg/kg, respectively) produced significant increase in liver-specific enzymes viz. plasma alkaline phosphatase,γ-glutamyl transferase, lactate dehydrogenase with a concomitant decrease in hepatic glutamic pyruvic transaminase. A corresponding increase in liver body weight index and histopathological changes in liver (degeneration of hepatocytes, congestion and hemorrhage etc.) are indicative of a dose and time dependent hepatotoxic nature of the algal extract展开更多

After giving CdCl2 (0. 44mg Cd/kg,ip), CPZ (5mg/kg, ip) or NIMO (8mg/kg, po) were administered every day to Sprague-Dawley (S. D. ) rats for a week. Then, urinary N- acetyl-β-D- glucosaminidase (NAG ), uri -nary cadmium and bloocl cadmium were measured. The accumulation of cadmium in the kid-ney cortex, content of renal calmodulin, hemoglobin and the ultrastructural damage of proxi-mal convoluted tubules of rats were examined three weeks after the last administration. Re-sults indicated that the calcium antagonists partly protected against toxic effects induced bycadmium in different manners. These data provide further evidence for the new hypothesisthat the cross effect of cadmium and calcium in calmodulin regulated systems may be responsi-ble for the mechanism of cadmium intoxication. 'The results suggested that the calcium antag-onists could be a new and promising approach in the therapy of heavy metaLinduced diseases展开更多

We present 5 cases of hepatocellular carcinoma treated with liver resection plus sorafenib, trying to observing the adverse effects and seeking the nursing options to the adverse effects. The 5 patients were all males, and the mean age was (38.6-a:13.4) years. Tumor sizes were (6.7+2.2) cm, and liver function was Child-Pugh class A. Diagnosis of Hepatocellular carcinoma (HCC) was confwmed by postoperative pathology. During the follow-ups, all the 5 patients had different degrees of adverse effects, of which 5 patients had diarrhea, 3 had hand-foot skin reaction, 1 had hypertension and 1 had alopecie. Diarrhea seems common in these patients, and it appeared early after treatment. For those patients with adverse effects, management measures were given immediately, including nursing interventions and some medicines. Psychological and symptomatic nursing guidance can help patients overcome the adverse effects. No patients suffered dose reduction or treatment discontinuation.展开更多

The adverse effects of FMD vaccine to pigs, cattle and goats have been reported increasingly frequent during the spring and autumn seasons when large numbers of farm livestock are vaccinated. The financial losses caused by vaccine adverse effects have been a serious concern for both farmers and primary prevention personnel. There are various causative factors reported to involve into adverse effect of FMD vaccine, including the inappropriate vaccine production, transportation and storage, livestock poor tolerance, and unqualified vaccinating manipulations. Symptomatic treatment and early drug prevention have a certain effect on the adverse effects. To analyze causes and propose countermeasures, in the current study possible reasons during the production and processing procedures of inactivated FMD vaccine were reviewed and corresponding countermeasures were recommended. The review may provide references for better use of vaccine to prevent FMD.展开更多

The increasing output of OPFRs and the increasing detection of OPFRs in environmental media have attracted wide attention of scholars at home and abroad. OPFRs are generally semi-volatile, easy to enter the environment and accumulate in organisms,causing potential hazards to the environment and human health. In this paper, the pollution status and toxic effects of OPFRs in aquatic environment were introduced,and the research progress of human health risk caused by them was summarized.The existing problems were pointed out, and the future research was prospected. In the future, the analytical methods of various environmental and biological media should be improved, and comprehensive and in-depth environmental investigation and ecological and health risk assessment should be carried out. Attention should be paid to the effects of combined pollution on organisms and the study of biological acceptability.展开更多

The prevalence is between 5% - 30%. CVI is associated with older age, smoking, lower extremity trauma, presence of an arteriovenous shunt, and elevated estrogen levels. All patients should be initially treated with conservative management. Venoactive drugs like calcium dobesilate are useful. Objectives: The primary objective compared the clinical improvement in patients with CVI, grades 0 - 3 of the CEAP classification of chronic venous disease, produced by two formulations of calcium dobesilate: calcium dobesilate LP 1 g OD vs calcium dobesilate 500 mg BID, immediate release. The secondary objective assessed the side effects of both formulations. Method: All patients took one tablet and one capsule at 7 am, and one capsule at 7 pm, for 8 weeks. One group received dobesilate 1 g OD and the other group received dobesilate 500 md BID. They were evaluated after 15, 30 and 60 days of treatment, using the symptom evaluation scale. Results: In both groups, there was a significant decrease in the symptom score after 15 days. Four patients in the Dobesilate OD group: had adverse effects, which did not require suspension of treatment. In the BID dobesilate group, there was one therapeutic failure, and one case of gastric discomfort. Conclusions: Prolonged-release Calcium dobesilate 1 g OD is as effective as calcium dobesilate 500 mg BID for the treatment of patients with chronic venous insufficiency.展开更多

We believe that these new developments will improve hormonal therapy. On the other hand, there has been an increase in criticism of hormonal therapy, because hormonal therapy is supposed to induce adverse effects such as cardiovascular disease. In this review, we have introduced the Japanese experience of hormonal therapy, because we believe that there may be ethnic differences between Caucasians and Asian people in the efficacy and adverse effects of hormonal therapy. First, we showed that primary hormonal therapy can achieve long-term control of localized prostate cancer in some cases and that quality of life of patients receiving hormonal therapy is rather better than previously thought. Neoadjuvant and adjuvant hormonal therapy in cases undergoing radical prostatectomy or radiotherapy are very useful for high-risk or locally advanced prostate cancer. Further clinical trials are required to confirm the efficacy of neoadjuvant or adjuvant hormonal therapy. We showed that the death from cardiovascular dis- eases in Japanese patients receiving hormonal therapy was not higher than that in the general population. However; efforts should be made to decrease the adverse effects of hormonal therapy, because life-style change may increase the susceptibility to adverse effects by hormonal therapy even in Japan. Managements of endocrine and metabolic dysfunction, such as diabetes mellitus, are essential. New hormonal compounds such as selective androgen receptor modulators capable of specifically targeting prostate cancer are expected to be developed.展开更多

The study was based on the gavage administration of the ethylic extract of Tl with different doses (i.e. 200, 400, 500 and 5000 mg/kg), where the toxicity and the sedative activity of the plant were observed and the obtained results were analyzed using the ANOVA test followed by the Bonferroni test. The main results of this study showed that the lethal dose of the ethylic extract of Tl was higher than the 5000 mg/kg dose. Moreover, when compared to the control rats, the animals treated with 5000 mg/kg of the extract exhibited significant reduction in appetite for food and water in the first week. Furthermore, results of the psychotropic test conducted during this study showed visible effects on the exploratory activity of the rats. The dose of 5000 mg/kg was also found to have a significant central nervous system effect;the locomotor activities of the animals decreased in a manner similar to those administered with Zepam as control.展开更多

However, reports of serious adverse effects such as life-threatening cardiac arrhythmias and sudden death raise questions about its safety. Objective: To investigate the incidence of significant adverse effects associated with low-dose methylprednisolone pulse therapy (LDMPT) in pediatric patients. Methods: We retrospectively analyzed adverse effects during and after LDMPT in 68 patients (median age: 11.4 years;43% male) with various glomerular diseases who were admitted to Saitama Children’s Medical Center between April 2007 and December 2010. LDMPT consisted of pulse methylprednisolone (15-20 mg/kg;maximum 600 mg/d) for 3 consecutive days weekly for 2-3 weeks. Results: Although adverse effects occurred in 54 of 68 patients (79%), most were mild and transient. Transient glycosuria was noted in 46 patients (68%), hypertension in 6 (9%), elevated intraocular pressure in 6 (9%), hypokalemia in 5 (7%), and liver damage in 2 (3%). No late-onset adverse effects such as osteoporotic fractures, steroid diabetes mellitus, or short stature were observed. Conclusion: LDMPT appears to be relatively safe and well tolerated in children with various glomerular diseases.展开更多
文摘[Objectives]To investigate the acute toxicity and hepatoprotective effect of Jinchuan formula plum wine extract on mice,determine its safety range,and evaluate its hepatoprotective effect.[Methods]The median lethal dose(LD_(50))was determined by acute toxicity test with the toxic reaction and mortality of mice as indexes.Sixty Kunming mice were randomly divided into 6 groups:normal control group,model group(ConA-induced liver injury model),Jinchuan formula plum wine high,medium and low dose groups(1.0,0.5,0.25 g/kg)and silybin group(0.1 g/kg).The levels of ALT,AST,LDH in serum and TG,VLDL in liver were measured.After HE staining,the pathological changes of liver tissue in mice were observed,and the liver protective effect of Jinchuan formula plum wine extract was analyzed and evaluated.[Results]LD_(50)was 11.18 g/kg,and the 95%confidence limit of LD_(50)was 10.31-12.05 g/kg.The high-dose group of Jinchuan formula plum wine extract could significantly reduce the serum ALT and AST activities of ConA-induced liver injury mice(P<0.05).[Conclusions]Jinchuan formula plum wine extract is relatively safe,and also has a protective effect on liver injury.
文摘Importance/Objective: Adverse Drug Reactions (ADRs) are unavoidable, but recognizing and addressing ADRs early can improve wellness and prevent permanent injury. We suggest that available medical information and digital/electronic methods could be used to manage this major healthcare problem for individual patients in real time. Methods: We searched the available digital applications and three literature databases using the medical subject heading terms, adverse drug reaction reporting systems or management, filtered by clinical trial or systemic reviews, to detect publications with data about ADR identification and management approaches. We reviewed the reports that had abstract or summary data or proposed or implemented methods or systems with potential to identify or manage ADRs in clinical settings. Results: The vast majority of the 481 reports used retrospectively collected data for groups of patients or were limited to surveying one population group or class of medication. The reports showed potential and definite associations of ADRs for specific drugs and problems, mostly, but not exclusively, for patients in hospitals and nursing homes. No reports described complete methods to collect comprehensive data on ADRs for individual patients in a healthcare system. The digital applications have ADR information, but all are too cumbersome or incomplete for use in active clinical settings. Several studies suggested that providing information about potential ADRs to clinicians can reduce these problems. Conclusion and Relevance: Although investigators and government agencies agree with the need, there is no comprehensive ADR management program in current use. Informing the patient’s healthcare practitioners of potential ADRs at the point of service has the potential for reduction of these complications, which should improve healthcare and reduce unneeded costs.
文摘Purpose:To study the adverse effects of frailty on elderly cancer patients and explore effective interventions.Methods:The convenience sampling method was used to select 362 elderly cancer patients who were consecutively admitted to the Oncology Department of the Affiliated Hospital of Hebei University from April 2020 to March 2021.The patients had five physical dimensions of activity tested and were divided into a frail group(n=128)and a non-frail group(n=234)based on the test results.The Chinese version of the Vulnerable Elders Questionnaire was formed on the basis of the Vulnerable Elders Survey-13(VES-13).The two groups of patients were surveyed within three days of admission.The questionnaire includes general information(age,gender,education level,marital status,monthly income,living area,smoking,and alcohol history,hearing,vision,and sleep status),Geriatric Depression Scale(GDS),Mini Nutritional Assessment(MNA),Mini-Mental State Examination(MMSE),and Charlson Comorbidity Index(CCI).Results:(1)By comparing the general information of the two groups of patients,it was found that the gender,education level,marital status,living area,and history of tobacco and alcohol had no statistical significance(P>0.05).In contrast,the frail group’s age,hearing status,vision status,and sleep status are significantly worse than those of the non-frail group(P<0.05);(2)Analysis of Vulnerable Elderly Questionnaire results found that the GDS scores in the frail group were higher than those in the non-frail group,and the MNA and MMSE scores were lower than those in the non-frail group(P<0.05).This indicated that the patients in the frail group had more severe depression,poor nutritional status,and specific impairments in cognitive function.Conclusion:Frailty adversely affects elderly cancer patients,and effective measures should be taken to intervene.
文摘Immunotherapy is rapidly evolving secondary to the advent of newer immunotherapeutic agents and increasing approval of the current agents by the United States Food and Drug Administration to treat a wide spectrum of cancers.Immunotherapeutic agents have gained immense popularity due to their tumorspecific action.Immunotherapy is slowly transforming into a separate therapeutic entity,and the fifth pillar of management for cancers alongside surgery,radiotherapy,chemotherapy,and targeted therapy.However,like any therapeutic entity it has its own adverse effects.With the increasing use of immunotherapeutic agents,it is vital for physicians to acquaint themselves with these adverse effects.The aim of this review is to investigate the common systemic adverse effects and toxicities associated with the use of different classes of immunotherapeutic agents.We provide an overview of potential adverse effects and toxicities associated with different classes of immunotherapeutic agents organized by organ systems,as well as an extensive discussion of the current recommendations for treatment and clinical trial data.As we continue to see increasing usage of these agents in clinical practice,it is vital for physicians to familiarize themselves with these effects.
文摘[ Objective] The toxicity effect of Hg^2+ and Cr(Ⅵ) on alga growth in eutrophic water was studied to provide reference for biomonitoring and bioremediation of eutrophic water. [ Method ] The mother liquid of alga, which was separated from the eutrophic water, were put into the solutions of Hg^2+ and Cr(Ⅵ) with different concentrations and their mixture solution, respectively. And the toxicity effect of Hg^2+ and Cr(Ⅵ) on the growth and propagation of alga in eutrophic water was observed. [ Result] The alga in eutrophic water performed rather sensitive to Cr(Ⅵ) and when its concentration was over 1 mg/L, threre was obvious effect on alga growth. The alga was not very sensitive to Hg^2+ when its concentration was lower, but its toxicity became stronger and stronger when its concentration increased to some extent and the toxicity effect of Cr(Ⅵ) on alga growth was just on the contrary. When the ion concentration was lower than 10 mg/L, the toxicity of Hg^2+ on alga was lower than that of Cr(Ⅵ). When the concentration was over 10 mg/L, the toxicity of Hg^2+ exceeded that of Cr(Ⅵ). The toxicity of ion mixture solution of Hg^2+ and Cr(Ⅵ) had synergism inhibition on alga, which could be performed only when the concentration was over 4 mg/L. [ Conclusion] The toxicity of heavy metal on alga not only related to the alga cell, but also related to the concentration of heavy metal ion.
文摘Gastrectomy with radical lymph node dissection is the most promising treatment avenue for patients with gastric cancer. However, this procedure sometimes induces excessive intraoperative blood loss and requires perioperative allogeneic blood transfusion. There are lasting discussions and controversies about whether intraoperative blood loss or perioperative blood transfusion has adverse effects on the prognosis in patients with gastric cancer. We reviewed laboratory and clinical evidence of these associations in patients with gastric cancer. A large amount of clinical evidence supports the correlation between excessive intraoperative blood loss and adverse effects on the prognosis. The laboratory evidence revealed three possible causes of such adverse effects: anti-tumor immunosuppression, unfavorable postoperative conditions, and peritoneal recurrence by spillage of cancer cells into the pelvis. Several systematic reviews and meta-analyses have suggested the adverse effects of perioperative blood transfusions on prognostic parameters such as all-cause mortality, recurrence, and postoperative complications. There are two possible causes of adverse effects of blood transfusions on the prognosis: Anti-tumor immunosuppression and patient-related confounding factors (e.g., preoperative anemia). These factors are associated with a worse prognosis and higher requirement for perioperative blood transfusions. Surgeons should make efforts to minimize intraoperative blood loss and transfusions during gastric cancer surgery to improve patients’ prognosis.
文摘Oral nucleoside/nucleotide analogues(NAs) are currently the backbone of chronic hepatitis B(CHB) infection treatment. They are generally well-tolerated by patients and safe to use. To date, a significant number of patients have been treated with NAs. Safety data has accumulated over the years. The aim of this article is to review and update the adverse effects of oral NAs. NAs can cause class adverse effects(i.e., myopathy, neuropathy, lactic acidosis) and dissimilar adverse effects. All NAs carry a "Black Box" warning because of the potential risk for mitochondrial dysfunction. However, these adverse effects are rarely reported. The majority of cases are associated with lamivudine and telbivudine. Adefovir can lead to dose- and time-dependent nephrotoxicity, even at low doses. Tenofovir has significant renal and bone toxicity in patients with human immunodeficiency virus(HIV) infection. However, bone and renal toxicity in patients with CHB are not as prominent as in HIV infection. Entecavir and lamivudine are not generally associated with renal adverse events. Entecavir has been claimed to increase the risk of lactic acidosis in decompensated liver disease and high Model for End-Stage Liver Disease scores. However, current studies reported that entecavir could be safely used in decompensated cirrhosis. An increase in fetal adverse events has not been reported with lamivudine, telbivudine and tenofovir use in pregnant women, while there is no adequate data regarding entecavir and adefovir. Further long-term experience is required to highlight the adverse effects of NAs, especially in special patient populations, including pregnant women, elderly and patients with renal impairment.

文摘Perfluorooctanoic acid(PFOA)is a widespread synthetic persistent organic pollutant that may enrich along the food chain and affect the growth,development,reproduction,and lipid metabolism of aquatic organisms,particularly the benthic organisms.How-ever,the toxic effects of PFOA on the half-smooth tongue sole Cynoglossus semilaevis,a commercial benthic fish in China,have rarely been reported.Because juvenile fish are sensitive to environmental pollutants,in the present study,histological assessment and tran-scriptome sequencing were performed to determine the short-term impact of PFOA on juvenile half-smooth tongue soles.Histologi-cal analysis showed that PFOA exposure caused hepatocyte rupture,intestinal villi breakage,increased goblet cell count,and brain ab-normal.Transcriptome results showed that some interesting signaling pathways,such as glycolysis/gluconeogenesis,PPAR signaling pathway and GABAergic synapse signaling pathway,were enriched after PFOA exposure.In addition,some metabolic,immune and neural genes were differentially expressed,which including ependymin,hbb1-like and gad 1,and they were up-regulated after 14 days of exposure.Transcriptome results also indicated that half-smooth tongue sole might improve energy metabolism in response to PFOA toxicity after 7 days of exposure.These findings provide a basis for studying the ecological effects of PFOA on marine benthic fishes.
文摘Laboratory cultures of freshwater cyanobacterium (blue-green alga) Microcystis aeruginosa PCC 7806 was cvaluated for its hepatotoxic effects in rats. The lyophilized cell extract injected intraperitoneally at 1 and 2 LD50 (15.8 and 31.6 mg/kg, respectively) produced significant increase in liver-specific enzymes viz. plasma alkaline phosphatase,γ-glutamyl transferase, lactate dehydrogenase with a concomitant decrease in hepatic glutamic pyruvic transaminase. A corresponding increase in liver body weight index and histopathological changes in liver (degeneration of hepatocytes, congestion and hemorrhage etc.) are indicative of a dose and time dependent hepatotoxic nature of the algal extract

文摘Protective effects of calcium antagonists, chlorpromazine (CPZ) and nimodepine (NI-MO), on cadmium-induced toxicity were investigated. After giving CdCl2 (0. 44mg Cd/kg,ip), CPZ (5mg/kg, ip) or NIMO (8mg/kg, po) were administered every day to Sprague-Dawley (S. D. ) rats for a week. Then, urinary N- acetyl-β-D- glucosaminidase (NAG ), uri -nary cadmium and bloocl cadmium were measured. The accumulation of cadmium in the kid-ney cortex, content of renal calmodulin, hemoglobin and the ultrastructural damage of proxi-mal convoluted tubules of rats were examined three weeks after the last administration. Re-sults indicated that the calcium antagonists partly protected against toxic effects induced bycadmium in different manners. These data provide further evidence for the new hypothesisthat the cross effect of cadmium and calcium in calmodulin regulated systems may be responsi-ble for the mechanism of cadmium intoxication. 'The results suggested that the calcium antag-onists could be a new and promising approach in the therapy of heavy metaLinduced diseases

文摘There were very few reports of adverse effects in patients treated by liver resection in combination with sorafenib. We present 5 cases of hepatocellular carcinoma treated with liver resection plus sorafenib, trying to observing the adverse effects and seeking the nursing options to the adverse effects. The 5 patients were all males, and the mean age was (38.6-a:13.4) years. Tumor sizes were (6.7+2.2) cm, and liver function was Child-Pugh class A. Diagnosis of Hepatocellular carcinoma (HCC) was confwmed by postoperative pathology. During the follow-ups, all the 5 patients had different degrees of adverse effects, of which 5 patients had diarrhea, 3 had hand-foot skin reaction, 1 had hypertension and 1 had alopecie. Diarrhea seems common in these patients, and it appeared early after treatment. For those patients with adverse effects, management measures were given immediately, including nursing interventions and some medicines. Psychological and symptomatic nursing guidance can help patients overcome the adverse effects. No patients suffered dose reduction or treatment discontinuation.
文摘Foot-and-mouth disease (FMD) is an infectious and sometimes fatal viral disease that affects cloven-hoofed animals, and Chinese government adopts compulsory immunization measures for FMD. The adverse effects of FMD vaccine to pigs, cattle and goats have been reported increasingly frequent during the spring and autumn seasons when large numbers of farm livestock are vaccinated. The financial losses caused by vaccine adverse effects have been a serious concern for both farmers and primary prevention personnel. There are various causative factors reported to involve into adverse effect of FMD vaccine, including the inappropriate vaccine production, transportation and storage, livestock poor tolerance, and unqualified vaccinating manipulations. Symptomatic treatment and early drug prevention have a certain effect on the adverse effects. To analyze causes and propose countermeasures, in the current study possible reasons during the production and processing procedures of inactivated FMD vaccine were reviewed and corresponding countermeasures were recommended. The review may provide references for better use of vaccine to prevent FMD.

文摘Organophosphorus flame retardants(OPFRs) are gradually replacing brominated flame retardants(BFRs), which are widely used in the world. The increasing output of OPFRs and the increasing detection of OPFRs in environmental media have attracted wide attention of scholars at home and abroad. OPFRs are generally semi-volatile, easy to enter the environment and accumulate in organisms,causing potential hazards to the environment and human health. In this paper, the pollution status and toxic effects of OPFRs in aquatic environment were introduced,and the research progress of human health risk caused by them was summarized.The existing problems were pointed out, and the future research was prospected. In the future, the analytical methods of various environmental and biological media should be improved, and comprehensive and in-depth environmental investigation and ecological and health risk assessment should be carried out. Attention should be paid to the effects of combined pollution on organisms and the study of biological acceptability.
文摘BACKGROUND Metoclopramide may be used to treat people suffering from acute migraine.However,no comprehensive investigation on this issue has been recorded.This review will provide more solid evidence for the use of metoclopramide in treating acute migraine.AIM To compare the efficacy of intravenous metoclopramide with other therapies in migraine attack treatment in an emergency department(ED).METHODS We included randomized controlled trials of participants older than 18 years with acute migraine headaches,which included at least one arm that received intravenous(IV)metoclopramide at the ED.A literature search of PubMed,Web of Science,Cochrane Collaboration,and Reference Citation Analysis on December 31,2021 retrieved other drugs or placebo-controlled studies without language limitation.The risk of bias was assessed using the Cochrane risk of bias tool.The primary endpoint was pain reduction at 60 min or closest to 1 h after treatment,as measured by the pain scale.Secondary endpoints included adverse effects or reactions resulting from metoclopramide or comparisons.RESULTS Fourteen trials with a total of 1661 individuals were eligible for review.The risk of bias ranged from low to intermediate.IV metoclopramide administration was not associated with higher pain reduction at 1 h(Standard mean difference[SMD]=-0.03,95%confidence interval[CI]:-0.33-0.28,P=0.87).However,metoclopramide was associated with better pain reduction than placebo(SMD=1.04,95%CI:0.50-1.58,P=0.0002).In addition,side effects were not significantly different between IV metoclopramide and other drugs or placebo(odds ratio[OR]=0.76,95%CI:0.48-1.19,P=0.09 and OR=0.92,95%CI:0.31-2.74,P=0.54,respectively).CONCLUSION Metoclopramide is more effective than placebo in treating migraine in the ED.Despite the observed tendency of decreased side effects,its effectiveness compared to other regimens is poorly understood.More research on this area is needed to treat migraine in acute care settings effectively.
文摘Background: Chronic venous insufficiency (CVI) describes a condition that affects the venous system of the lower extremities due to venous hypertension (VH. The prevalence is between 5% - 30%. CVI is associated with older age, smoking, lower extremity trauma, presence of an arteriovenous shunt, and elevated estrogen levels. All patients should be initially treated with conservative management. Venoactive drugs like calcium dobesilate are useful. Objectives: The primary objective compared the clinical improvement in patients with CVI, grades 0 - 3 of the CEAP classification of chronic venous disease, produced by two formulations of calcium dobesilate: calcium dobesilate LP 1 g OD vs calcium dobesilate 500 mg BID, immediate release. The secondary objective assessed the side effects of both formulations. Method: All patients took one tablet and one capsule at 7 am, and one capsule at 7 pm, for 8 weeks. One group received dobesilate 1 g OD and the other group received dobesilate 500 md BID. They were evaluated after 15, 30 and 60 days of treatment, using the symptom evaluation scale. Results: In both groups, there was a significant decrease in the symptom score after 15 days. Four patients in the Dobesilate OD group: had adverse effects, which did not require suspension of treatment. In the BID dobesilate group, there was one therapeutic failure, and one case of gastric discomfort. Conclusions: Prolonged-release Calcium dobesilate 1 g OD is as effective as calcium dobesilate 500 mg BID for the treatment of patients with chronic venous insufficiency.
文摘Recently, novel anti-androgens and inhibitors of androgen biosynthesis have been developed through the elucidation of mechanisms of castration resistance of prostate cancer. We believe that these new developments will improve hormonal therapy. On the other hand, there has been an increase in criticism of hormonal therapy, because hormonal therapy is supposed to induce adverse effects such as cardiovascular disease. In this review, we have introduced the Japanese experience of hormonal therapy, because we believe that there may be ethnic differences between Caucasians and Asian people in the efficacy and adverse effects of hormonal therapy. First, we showed that primary hormonal therapy can achieve long-term control of localized prostate cancer in some cases and that quality of life of patients receiving hormonal therapy is rather better than previously thought. Neoadjuvant and adjuvant hormonal therapy in cases undergoing radical prostatectomy or radiotherapy are very useful for high-risk or locally advanced prostate cancer. Further clinical trials are required to confirm the efficacy of neoadjuvant or adjuvant hormonal therapy. We showed that the death from cardiovascular dis- eases in Japanese patients receiving hormonal therapy was not higher than that in the general population. However; efforts should be made to decrease the adverse effects of hormonal therapy, because life-style change may increase the susceptibility to adverse effects by hormonal therapy even in Japan. Managements of endocrine and metabolic dysfunction, such as diabetes mellitus, are essential. New hormonal compounds such as selective androgen receptor modulators capable of specifically targeting prostate cancer are expected to be developed.
文摘The purpose of this study was to evaluate the acute toxicity and sedative effect of the ethylic extract of Thymelaea lythroides (Tl) on Wistar rats. The study was based on the gavage administration of the ethylic extract of Tl with different doses (i.e. 200, 400, 500 and 5000 mg/kg), where the toxicity and the sedative activity of the plant were observed and the obtained results were analyzed using the ANOVA test followed by the Bonferroni test. The main results of this study showed that the lethal dose of the ethylic extract of Tl was higher than the 5000 mg/kg dose. Moreover, when compared to the control rats, the animals treated with 5000 mg/kg of the extract exhibited significant reduction in appetite for food and water in the first week. Furthermore, results of the psychotropic test conducted during this study showed visible effects on the exploratory activity of the rats. The dose of 5000 mg/kg was also found to have a significant central nervous system effect;the locomotor activities of the animals decreased in a manner similar to those administered with Zepam as control.
文摘Background: Intravenous methylprednisolone pulse therapy has been used since the late 1960s for acute transplant rejection or severe renal involvement in systemic lupus erythematosus and primary glomerulonephritis. However, reports of serious adverse effects such as life-threatening cardiac arrhythmias and sudden death raise questions about its safety. Objective: To investigate the incidence of significant adverse effects associated with low-dose methylprednisolone pulse therapy (LDMPT) in pediatric patients. Methods: We retrospectively analyzed adverse effects during and after LDMPT in 68 patients (median age: 11.4 years;43% male) with various glomerular diseases who were admitted to Saitama Children’s Medical Center between April 2007 and December 2010. LDMPT consisted of pulse methylprednisolone (15-20 mg/kg;maximum 600 mg/d) for 3 consecutive days weekly for 2-3 weeks. Results: Although adverse effects occurred in 54 of 68 patients (79%), most were mild and transient. Transient glycosuria was noted in 46 patients (68%), hypertension in 6 (9%), elevated intraocular pressure in 6 (9%), hypokalemia in 5 (7%), and liver damage in 2 (3%). No late-onset adverse effects such as osteoporotic fractures, steroid diabetes mellitus, or short stature were observed. Conclusion: LDMPT appears to be relatively safe and well tolerated in children with various glomerular diseases.
