In Côte d’Ivoire, the first vaccination campaign with the AstraZeneca vaccine began on March 1, 2021, as part of the Covax program. Despite the positive benefit/risk balance, the adverse effects of vaccination should not be minimized. Objective: To identify adverse events of AstraZeneca’s COVID-19 vaccination for better management. Materials and Methods: This is a case of a 57-year-old obese (BMI = 39 kg/m2) female health care worker who experienced adverse events in March 2021 after the second dose of AstraZeneca vaccine administered 4 weeks apart. These were subject to mandatory case reporting. Results: Major post-vaccination events occurred in a noisy systemic picture with parameters showing significant disturbances. Biological surveillance remains costly and makes the accountability of the vaccine complex. Conclusion: Vaccination remains the ultimate weapon in the fight against endemic diseases but should not overshadow the reporting of adverse events.展开更多

It was therefore important to revisit the causes but especially the adverse events associated with care (EIS) in maternity. Objective: Determine the incidence, adverse events associated with care and causes of intra hospital maternal mortality in cotonou. Methods: This was a cross-sectional maternal mortality review study with retrospective data collection. It covered all cases of maternal death recorded between 2017 and 2021 in two (2) reference university maternities in Cotonou. Adverse events associated with care and the patient were analyzed using the maternal death audit grid validated for Benin. SPSS.26 software was used for data analysis. Results: The in-hospital maternal mortality ratio in Cotonou was 2028 maternal deaths per 100,000 live births in 2021. Only 7.2% (n = 36) of deaths were audited. The deceased mothers were 29.8 ± 7.4 years old, with no fixed monthly income in 82.7% (n = 420). Serious adverse events associated with care were: delay in decision to refer in 37% (n = 188), non-medical referral in 85.8% (n = 436) of cases, inadequate pre-referral treatment in 25.7% of cases. In receiving maternities, delay in diagnosis and inappropriate treatment at the receiving maternity were noted respectively in 22.9% and 28.6% of cases of maternal death. The direct causes of maternal death were dominated by serious obstetric hemorrhage in 43.9% (n = 223). As for the indirect causes, they were dominated by anemia excluding obstetric hemorrhages in 21.5% (n = 109). Conclusion: The in-hospital maternal mortality ratio was very high in Cotonou. The main cause was severe obstetric hemorrhage. There were several serious healthcare-associated adverse events whose correct management would significantly reduce the incidence of maternal deaths.展开更多

The aims of this study were to evaluate the tolerance and survival of sorafenib-treated patients, and to identify potential prognostic factors of survival. Methods: A total of 88 HCC patients treated with sorafenib from June 2010 to January 2014 were retrospectively reviewed. Tumour stage, liver function and adverse events to sorafenib were analyzed. Univariate and multivariate analysis were carried out to identify predictors of survival in patients with advanced HCC treated with sorafenib. Results: There were 64 (73%) males included in this study, with a median age of 61.16 years. Eight (91%) patients had Child-Pugh class A cirrhosis. Most patients were classified as BCLC C (82%). Hepatitis C virus was the predominant cause of HCC (68%). Sorafenib was the initial treatment modality in 43%. Median time of sorafenib therapy was 8.23 months. Overall survival in 1 year was 57.3% and 36.7% in 2 years. The median survival was 16.3 months. In the univariate analysis of the OS based on Child-Pugh score did not demonstrate a significant difference in our study (p = 0.62). The presence of dermatologic adverse event predicted a better overall survival in the multivariate analysis. Better survival was also observed in patients with AFP level <100 ng/ml in the start of sorafenib therapy (p = 0.001). Patients that used Sorafenib for ≥6 months had shown better outcome. None of the patients discontinued sorafenib because of adverse effects. Conclusions: Advanced HCC patients treated with sorafenib who experienced dermatologic adverse event and low AFP level <100 ng/ml showed better overall survival. As expected, longer sorafenib therapy (≥6 months) was associated to better survival. Even in the presence of adverse events, the use of sorafenib should be continued because the longer usage time improves survival.展开更多

Adverse events were identified via chart review. IBD serologies were measured by ELISA. DNA samples were genotyped at Cedars-Sinai using Illumina Infinium Immunochipv1 array per manufacturer's protocol. SNPs underwent methodological review and were evaluated using several SNP statistic parameters to ensure optimal allele-calling. Standard and rigorous QC criteria were applied to the genetic data, which was generated using immunochip. Genetic association was assessed by logistic regression after correcting for population structure.RESULTS Altogether we identified 1258 IBD subjects exposed to anti-TNF agents in whom Immunochip data were available. 269/1258 patients(21%) were found to have adverse events to an anti-TNF-α agent that required the therapy to be discontinued. 25% of women compared to 17% of men experienced an adverse event. All adverse events resolved after discontinuing the antiTNF agent. In total: n = 66(5%) infusion reactions; n = 49(4%) allergic/serum sickness reactions; n = 19(1.5%) lupus-like reactions, n = 52(4%) rash, n = 18(1.4%) infections. In Crohn's disease, Ig A ASCA(P = 0.04) and Ig G-ASCA(P = 0.02) levels were also lower in patients with any adverse events, and anti-I2 level in ulcerative colitis was significantly associated with infusion reactions(P = 0.008). The logistic regression/human annotation and network analyses performed on the Immunochip data implicated the following five signaling pathways: JAK-STAT(Janus Kinase-signal transducer and activator of transcription), measles, IBD, cytokine-cytokine receptor interaction, and toxoplasmosis for any adverse event. CONCLUSION Our study shows 1 in 5 IBD patients experience an adverse event to anti-TNF therapy with novel serologic, genetic, and pathways associations.展开更多

METHODS Polypectomies of protruded gastric or duodenal polyps ≥ 5 mm using hot snare were prospectively included. Prophylactic measures of hemorrhage were allowed in predefined cases. AEs were defined and graded according to the lexicon recommended by the American Society for Gastrointestinal Endoscopy. Patients were followed for 48 h, one week and 1 mo after theprocedure. RESULTS308 patients were included and a single polypectomy was performed in 205. Only 36(11.7%) were on prior anticoagulant therapy. Mean polyp size was 15 ± 8.9 mm(5-60) and in 294 cases(95.4%) were located in the stomach. Hemorrhage prophylaxis was performed in 219(71.1%) patients. Nine patients presented AEs(2.9%), and 6 of them were bleeding(n = 6, 1.9%)(in 5 out of 6 AE, different types of endoscopic treatment were performed). Other 24 hemorrhagic episodes could be managed without any change in the outcome of the endoscopy and, consequently, were considered incidents. We did not find any independent risk factor of bleeding.CONCLUSION Gastroduodenal polypectomy using prophylactic measures has a rate of AEs small enough to consider this procedure a safe and effective method for polyp resection independently of the polyp size and location.展开更多

Endoscopic papillectomy is one of the main treatments for papillary adenoma, and bleeding, perforation, and pancreatitis are the most frequent and critical adverse events that restrict its wider use. There is no standard procedure for endoscopic papillectomy yet. The procedure is relevant to postoperative adverse events.AIM To reduce the postoperative adverse event rates and improve patients' postoperative condition, we developed a standard novel procedure for endoscopic papillectomy.METHODS The novel endoscopic papillectomy had two main modifications based on the conventional method: The isolation of bile from pancreatic juice with a bile duct stent and wound surface protection with metal clips and fibrin glue. We performed a single-center retrospective comparison study on the novel and conventional methods to examine the feasibility of the novel method for reducing postoperative adverse events.RESULTS A total of 76 patients, of whom 23 underwent the novel procedure and 53 underwent the conventional procedure, were retrospectively evaluated in this study. The postoperative bleeding and pancreatitis rates of the novel method were significantly lower than those of the conventional method(0 vs 20.75%, P = 0.028, and 17.4% vs 41.5%, P = 0.042, respectively). After applying the novel method, the most critical adverse event, perforation, was entirely prevented, compared to a prevalence of 5.66% with the conventional method. Several postoperative symptoms, including fever, rapid pulse, and decrease in hemoglobin level, were significantly less frequent in the novel group(P = 0.042, 0.049, and 0.014, respectively). Overall, the total adverse event rate of the novel method was lower(0 vs 24.5%, P = 0.007) than that of the conventional method.CONCLUSION Patients who underwent the novel procedure had lower postoperative adverse event rates. This study demonstrates the potential efficacy and safety of the novel endoscopic papillectomy in reducing postoperative adverse events.展开更多

Despite the excellent therapeutic effects of ICIs, medications, such as pembrolizumab, ipilimumab, nivolumab, atezolizumab, avelumab, and durvalumab, typically cause a broad spectrum of toxicity events termed as immune-related adverse events(ir AEs). Out of all ir AEs, ophthalmic adverse events occur infrequently and are not comprehensively recognized. The current understanding of ophthalmic ir AEs is mainly derived from case reports and case series. In this review, based on relevant articles in the literature and current evidence, we summarize the incidences, manifestations, diagnoses, underlying mechanisms, treatments, and outcomes of ophthalmic ir AEs and discuss possible management strategies. A better understanding of these features is critical for managing patients with ICI-associated ophthalmic adverse events.展开更多

METHODS: The relevant data of perioperative period were collected in our hospital during 2010-2012, and the medical quality of perioperative period was evaluated by using the traditional evaluation indexes and adverse events. Whereby, the traditional indicators include vision changes, improving of intraocular pressure, diagnostic accordance rate before and after operation, cure improvement rate, successful rescue rate, and incidence of surgical complications, etc Adverse events are associated with ophthalmologic perioperative events including pressure sores, postoperative wound infection, drug adverse events, and equipment related adverse events. RESULTS: There were 1483, 1662 and 1931 ophthalmic operations in our hospital in the year 2010, 2011 and 2012, respectively. From traditional index analysis, the proportions of vision improvement for each year were 96.43%, 96.76% and 97.32%, respectively; the rates of intraocular pressure improvement were 87.50%, 85.72% and 90.17%, respectively ( P <0.05); the diagnostic accordance rates before and after operation were 99.86%, 99.94% and 99.90%, respectively; cure improvement rates were 99.73%, 99.93% and 99.84%, respectively; the successful rescue rates were 82.98%, 81.46% and 76.66%, respectively; the complications incidence rates were 18.44%, 17.52% and 17.97%, respectively. The negative factor analysis results showed that: among all the patients of ophthalmic surgeries in our hospital during 2010 and 2012, only one case of postoperative wound infection was found in 2011, and also only one case of tumbling in 2010. The adverse drug events for each year were 1 case (0.07%), 2 cases (0.12%), and 4 cases (0.21%), respectively; the medical device adverse events for each year were 3 cases (0.20%), 5 cases (0.30%), and 6 cases (0.31%), respectively. Noticeably, only one case with postoperative infection of endophthalmitis was found in 2011. Moreover, no pulmonary infection or pulmonary embolism occurred during the three years. The perioperative adverse event rates for each year were 0.34% (5/1483), 0.48% (8/1662) and 0.52% (10/1931), respectively. Though incidence was rising during the three years, no statistical significance was observed (P>0.05). It is the same case with drugs and medical devices adverse events (P>0.05). CONCLUSION: Traditional indicators reflect an excellent operation of the perioperative ophthalmologic quality, whereas adverse events analysis indicates some underlying problems. Compared with the traditional indexes for medical quality evaluation, the index of adverse events is more reasonable and easier to make an objective evaluation for medical quality of ophthalmologic perioperation, facilitating further refine analysis. Reasonable application of the adverse events indicators helps hospital to make the detailed quality control measures.展开更多

文摘We conducted a comprehensive review of existing prediction models pertaining to the efficacy of immune-checkpoint inhibitor(ICI)and the occurrence of immune-related adverse events(irAEs).The predictive potential of neutrophil-to-lymphocyte ratio(NLR)and platelet-to-lymphocyte ratio(PLR)in determining ICI effectiveness has been extensively investigated,while limited research has been conducted on predicting irAEs.Furthermore,the combined model incor-porating NLR and PLR,either with each other or in conjunction with additional markers such as carcinoembryonic antigen,exhibits superior predictive capabilities compared to individual markers alone.NLR and PLR are promising markers for clinical applications.Forthcoming models ought to incorporate established efficacious models and newly identified ones,thereby constituting a multifactor composite model.Furthermore,efforts should be made to explore effective clinical application approaches that enhance the predictive accuracy and efficiency.
文摘BACKGROUND Intravenous infusion is a common method of drug administration in clinical practice.Errors in any aspect of the infusion process,from the verification of medical orders,preparation of the drug solution,to infusion by nursing staff,may cause adverse infusion events.AIM To analyzed the value of improving nursing measures and enhancing nursing management to reduce the occurrence of adverse events in pediatric infusion.METHODS The clinical data of 130 children who received an infusion in the pediatric department of our hospital from May 2020 to May 2021 were analyzed and divided into two groups according to the differences in nursing measures and nursing management:65 patients in the control group received conventional nursing and nursing management interventions,while 65 patients in the observation group received improved nursing measure interventions and enhanced nursing management.The occurrence of adverse events,compliance of children,satisfaction of children’s families,and complaints regarding the transfusion treatment were recorded in both groups.RESULTS The incidence of fluid extravasation and infusion set dislodgement in the observation group were 3.08%and 1.54%,respectively,which were significantly lower than 12.31%and 13.85%in the control group(P<0.05),while repeated punctures and medication addition errors in the observation group were 3.08%and 0.00%,respectively,which were lower than 9.23%and 3.08%in the control group,but there was no significant difference(P>0.05).The compliance rate of children in the observation group was 98.46%(64/65),which was significantly higher than 87.69%(57/65)in the control group,and the satisfaction rate of children’s families was 96.92%(63/65),which was significantly higher than 86.15%(56/65)in the control group(P<0.05).The observation group did not receive any complaints from the child’s family,whereas the control group received four complaints,two of which were due to the crying of the child caused by repeated punctures,one due to the poor attitude of the nurse,and one due to medication addition errors,with a cumulative complaint rate of 6.15%.The cumulative complaint rate of the observation group was significantly lower than that of the control group(P<0.05).CONCLUSION Improving nursing measures and enhancing nursing management can reduce the incidence of fluid extravasation and infusion set dislodgement in pediatric patients,improve children’s compliance and satisfaction of their families,and reduce family complaints.
文摘Introduction: Pharmaceutical companies have boosted vaccine production following the global COVID-19 pandemic. In Côte d’Ivoire, the first vaccination campaign with the AstraZeneca vaccine began on March 1, 2021, as part of the Covax program. Despite the positive benefit/risk balance, the adverse effects of vaccination should not be minimized. Objective: To identify adverse events of AstraZeneca’s COVID-19 vaccination for better management. Materials and Methods: This is a case of a 57-year-old obese (BMI = 39 kg/m2) female health care worker who experienced adverse events in March 2021 after the second dose of AstraZeneca vaccine administered 4 weeks apart. These were subject to mandatory case reporting. Results: Major post-vaccination events occurred in a noisy systemic picture with parameters showing significant disturbances. Biological surveillance remains costly and makes the accountability of the vaccine complex. Conclusion: Vaccination remains the ultimate weapon in the fight against endemic diseases but should not overshadow the reporting of adverse events.

文摘Lymphoma,which is highly malignant,stems from lymph nodes and lymphoid tissue.Lymphoma cells express programmed death-ligand 1/2(PD-L1/PD-L2),which binds with programmed cell death 1 protein(PD-1)to establish inhibitory signaling that impedes the normal function of T cells and allows tumor cells to escape immune system surveillance.Recently,immune checkpoint inhibitor immunotherapies such as PD-1 inhibitors(nivolumab and pembrolizumab)have been introduced into the lymphoma treatment algorithm and have shown remarkable clinical efficacy and greatly improve prognosis in lymphoma patients.Accordingly,the number of lymphoma patients who are seeking treatment with PD-1 inhibitors is growing annually,which results in an increasing number of patients developing immune-related adverse events(irAEs).The occurrence of irAEs inevitably affects the benefits provided by immunotherapy,particularly when PD-1 inhibitors are applied.However,the mechanisms and characteristics of irAEs induced by PD-1 inhibitors in lymphoma need further investigation.This review article summarizes the latest research advances in irAEs during treatment of lymphoma with PD-1 inhibitors.A comprehensive understanding of irAEs incurred in immunotherapy can help to achieve better efficacy with PD-1 inhibitors in lymphoma.
文摘Tumor necrosis factor inhibitors(anti-TNFs)are widely used therapies for the treatment of inflammatory bowel diseases(IBD);however,their administration is not risk-free.Heart failure(HF),although rare,is a potential adverse event related to administration of these medications.However,the exact mechanism of development of HF remains obscure.TNFαis found in both healthy and damaged hearts.Its effects are concentration-and receptor-dependent,promoting either cardio-protection or cardiomyocyte apoptosis.Experimental rat models with TNFαreceptor knockout showed increased survival rates,less reactive oxygen species formation,and improved diastolic left ventricle pressure.However,clinical trials employing anti-TNF therapy to treat HF had disappointing results,suggesting abolishment of the cardioprotective properties of TNFα,making cardiomyocytes susceptible to apoptosis and oxidation.Thus,patients with IBD who have risk factors should be screened for HF before initiating anti-TNF therapy.This review aims to discuss adverse events associated with the administration of anti-TNF therapy,with a focus on HF,and propose some approaches to avoid cardiac adverse events in patients with IBD.
文摘Objective:This systematized review aimed to synthesize the results of empirical studies focused on the types and factors of adverse events(AEs)that contribute to them in long-term care(LTC)settings.Methods:The search was conducted in Pro Quest,Scopus,and Pub Med in January 2021 and resulted in 1057 records.The content analysis method was used in the data analysis.Results:In all,35 studies were identified as relevant for the review.The analysis revealed 133 different types of AEs and 60 factors that contributed to them.Conclusions:In LTC,various AEs occur,most of which are preventable,while many factors that influence their occurrence could be significantly modifiable.Through an effective analysis of AEs in LTC,it is possible to minimize their occurrence and,at the same time,minimize their negative impact on all par ties concerned.
文摘Introduction: Despite the many efforts made to combat preventable maternal deaths, these still remain high in Benin. It was therefore important to revisit the causes but especially the adverse events associated with care (EIS) in maternity. Objective: Determine the incidence, adverse events associated with care and causes of intra hospital maternal mortality in cotonou. Methods: This was a cross-sectional maternal mortality review study with retrospective data collection. It covered all cases of maternal death recorded between 2017 and 2021 in two (2) reference university maternities in Cotonou. Adverse events associated with care and the patient were analyzed using the maternal death audit grid validated for Benin. SPSS.26 software was used for data analysis. Results: The in-hospital maternal mortality ratio in Cotonou was 2028 maternal deaths per 100,000 live births in 2021. Only 7.2% (n = 36) of deaths were audited. The deceased mothers were 29.8 ± 7.4 years old, with no fixed monthly income in 82.7% (n = 420). Serious adverse events associated with care were: delay in decision to refer in 37% (n = 188), non-medical referral in 85.8% (n = 436) of cases, inadequate pre-referral treatment in 25.7% of cases. In receiving maternities, delay in diagnosis and inappropriate treatment at the receiving maternity were noted respectively in 22.9% and 28.6% of cases of maternal death. The direct causes of maternal death were dominated by serious obstetric hemorrhage in 43.9% (n = 223). As for the indirect causes, they were dominated by anemia excluding obstetric hemorrhages in 21.5% (n = 109). Conclusion: The in-hospital maternal mortality ratio was very high in Cotonou. The main cause was severe obstetric hemorrhage. There were several serious healthcare-associated adverse events whose correct management would significantly reduce the incidence of maternal deaths.
文摘Objective:To develop nursing adverse events’reporting content of hospital.Methods:The study included two phases.The first phase was to develop the category and definition of nursing adverse events that need to be reported through an expert meeting.The second phase was to develop every nursing adverse event’s reporting content by using the Delphi method.In total,8 experts attended the meeting and 15 experts conducted two rounds of consultation letter.Results:Nursing adverse events that need to be reported of hospital include pressure sore,fall/falling from bed,unplanned extubation,medication error,and accident.Reporting content of these events in detail had also been obtained,which was helpful for cause analysis systematically.Conclusions:The reporting content of the nursing adverse event of hospital is established,and it is a basis for further study of the development of nursing adverse event reporting and feedback system.
文摘Introduction: Sorafenib is an orally active multikinase inhibitor approved for the treatment of advanced hepatocellular carcinoma (HCC) and is the only systemic treatment associated with a survival benefit in advanced stage. The aims of this study were to evaluate the tolerance and survival of sorafenib-treated patients, and to identify potential prognostic factors of survival. Methods: A total of 88 HCC patients treated with sorafenib from June 2010 to January 2014 were retrospectively reviewed. Tumour stage, liver function and adverse events to sorafenib were analyzed. Univariate and multivariate analysis were carried out to identify predictors of survival in patients with advanced HCC treated with sorafenib. Results: There were 64 (73%) males included in this study, with a median age of 61.16 years. Eight (91%) patients had Child-Pugh class A cirrhosis. Most patients were classified as BCLC C (82%). Hepatitis C virus was the predominant cause of HCC (68%). Sorafenib was the initial treatment modality in 43%. Median time of sorafenib therapy was 8.23 months. Overall survival in 1 year was 57.3% and 36.7% in 2 years. The median survival was 16.3 months. In the univariate analysis of the OS based on Child-Pugh score did not demonstrate a significant difference in our study (p = 0.62). The presence of dermatologic adverse event predicted a better overall survival in the multivariate analysis. Better survival was also observed in patients with AFP level <100 ng/ml in the start of sorafenib therapy (p = 0.001). Patients that used Sorafenib for ≥6 months had shown better outcome. None of the patients discontinued sorafenib because of adverse effects. Conclusions: Advanced HCC patients treated with sorafenib who experienced dermatologic adverse event and low AFP level <100 ng/ml showed better overall survival. As expected, longer sorafenib therapy (≥6 months) was associated to better survival. Even in the presence of adverse events, the use of sorafenib should be continued because the longer usage time improves survival.

文摘Objective:We aimed to retrospectively analyze the toxicity profiles and predictors of immune-related adverse events(irAEs)as well as the correlation between irAEs and the clinical efficacy of multi-type immune checkpoint inhibitors(ICIs)in patients with advanced pan-cancer in a real-world setting.Methods:We retrospectively analyzed data from 105 patients with advanced pan-cancer treated with multi-type ICIs at the First Hospital of Jilin University between January 1,2016 and August 1,2020.We used logistic regression analyses to investigate the associations of irAEs with clinical baseline characteristics,blood count parameters,and biochemical indicators during treatment.Receiver operating characteristic curves were used to determine cutoff values for parameters and area under the curve values.Kaplan–Meier and Cox multivariate regression analyses were performed to estimate the relationships of baseline characteristics and irAEs with progression-free survival(PFS)and overall survival(OS).Results:A lower relative lymphocyte count(cutoff=28.5%),higher albumin level(cutoff=39.05 g/L),and higher absolute eosinophil count(AEC)(cutoff=0.175×10^(9)/L)were significantly associated with the occurrence of irAEs,among which a higher AEC(cutoff=0.205×10^(9)/L)was strongly associated with skin-related irAEs[odds ratios(ORs)=0.163,P=0.004].Moreover,a higher lactate dehydrogenase level(cutoff=237.5 U/L)was an independent predictor of irAEs of grade≥3(OR=0.083,P=0.023).In immune cell subgroup analysis,a lower absolute count of CD8+CD28−suppressor T cells(OR=0.806;95%confidence interval:0.643–1.011;P=0.062),which are regulatory T lymphocytes,was associated with the occurrence of irAEs,although the difference was not statistically significant.Furthermore,a higher percentage of CD19+B cells was associated with the occurrence of irAEs of grade≥3(P=0.02)and grade≥2(P=0.051).In addition,patients with any grade of irAE had a significantly high PFS(8.37 vs.3.77 months,hazard ratios(HR)=2.02,P=0.0038)and OS(24.77 vs.13.83 months,HR=1.84;P=0.024).Conclusions:This retrospective study reports clinical profile data for irAEs in unselected patients in a real-world setting and explored some parameters that may be potential predictive markers of the occurrence,type,or grade of irAEs in clinical practice.Evidence of a correlation between safety and efficacy may facilitate a complete assessment of the risk-benefit ratio for patients treated with ICIs.
文摘AIM To study the type and frequency of adverse events associated with anti-tumor necrosis factor(TNF)therapy and evaluate for any serologic and genetic associations.METHODS This study was a retrospective review of patients attending the inflammatory bowel disease(IBD) centers at Cedars-Sinai IBD Center from 2005-2016. Adverse events were identified via chart review. IBD serologies were measured by ELISA. DNA samples were genotyped at Cedars-Sinai using Illumina Infinium Immunochipv1 array per manufacturer's protocol. SNPs underwent methodological review and were evaluated using several SNP statistic parameters to ensure optimal allele-calling. Standard and rigorous QC criteria were applied to the genetic data, which was generated using immunochip. Genetic association was assessed by logistic regression after correcting for population structure.RESULTS Altogether we identified 1258 IBD subjects exposed to anti-TNF agents in whom Immunochip data were available. 269/1258 patients(21%) were found to have adverse events to an anti-TNF-α agent that required the therapy to be discontinued. 25% of women compared to 17% of men experienced an adverse event. All adverse events resolved after discontinuing the antiTNF agent. In total: n = 66(5%) infusion reactions; n = 49(4%) allergic/serum sickness reactions; n = 19(1.5%) lupus-like reactions, n = 52(4%) rash, n = 18(1.4%) infections. In Crohn's disease, Ig A ASCA(P = 0.04) and Ig G-ASCA(P = 0.02) levels were also lower in patients with any adverse events, and anti-I2 level in ulcerative colitis was significantly associated with infusion reactions(P = 0.008). The logistic regression/human annotation and network analyses performed on the Immunochip data implicated the following five signaling pathways: JAK-STAT(Janus Kinase-signal transducer and activator of transcription), measles, IBD, cytokine-cytokine receptor interaction, and toxoplasmosis for any adverse event. CONCLUSION Our study shows 1 in 5 IBD patients experience an adverse event to anti-TNF therapy with novel serologic, genetic, and pathways associations.
文摘AIM To evaluate the rate of adverse events(AEs) during consecutive gastric and duodenal polypectomies in several Spanish centers. METHODS Polypectomies of protruded gastric or duodenal polyps ≥ 5 mm using hot snare were prospectively included. Prophylactic measures of hemorrhage were allowed in predefined cases. AEs were defined and graded according to the lexicon recommended by the American Society for Gastrointestinal Endoscopy. Patients were followed for 48 h, one week and 1 mo after theprocedure. RESULTS308 patients were included and a single polypectomy was performed in 205. Only 36(11.7%) were on prior anticoagulant therapy. Mean polyp size was 15 ± 8.9 mm(5-60) and in 294 cases(95.4%) were located in the stomach. Hemorrhage prophylaxis was performed in 219(71.1%) patients. Nine patients presented AEs(2.9%), and 6 of them were bleeding(n = 6, 1.9%)(in 5 out of 6 AE, different types of endoscopic treatment were performed). Other 24 hemorrhagic episodes could be managed without any change in the outcome of the endoscopy and, consequently, were considered incidents. We did not find any independent risk factor of bleeding.CONCLUSION Gastroduodenal polypectomy using prophylactic measures has a rate of AEs small enough to consider this procedure a safe and effective method for polyp resection independently of the polyp size and location.
文摘BACKGROUND Endoscopic retrograde cholangiopancreatography(ERCP)is a valuable therapeutic technique for pancreatobiliary diseases,and its application in the elderly is no longer limited.However,a higher incidence of procedure difficulty and periprocedural adverse events might be expected in elderly patients due to the presence of other medical disorders and the poor general condition of this population.AIM To evaluate the incidence,causes,and management of difficult biliary cannulation during ERCP in elderly patients and the role of difficult cannulation as a risk factor for adverse events.METHODS A total of 614 patients who underwent ERCP during the study period were prospectively studied and divided into two groups based on their age.One hundred and forty-six patients were aged 80 years or older and 468 patients were aged less than 80 years.The primary outcome measurements were cannulation difficulty,cannulation success rate,ERCP procedure time,and related adverse events.RESULTS There was no difference in the incidence of difficult cannulation among the two groups(32.9%vs 34.4%,P=0.765),as well as in the cannulation success rate(96.6%vs 96.8%,P=0.54).The cannulation techniques were shown to be safe and efficient in achieving successful cannulation.Logistic regression analysis showed that patients aged 80 years or older were not associated with increased adverse events;however,difficult cannulation cases[adjusted odds ratio(AOR)=3.478;95%confidence interval(CI):1.877-6.442;P<0.001]and patients with Charlson Comorbidity Index≥2(AOR=1.824;95%CI:0.993-3.349;P=0.045)were more likely to develop adverse events.In contrast,other factors including age≤65(AOR=3.460;95%CI:1.511-7.922;P=0.003),female gender(AOR=2.362;95%CI=1.089-5.124;P=0.030),difficult cannulation(AOR=4.527;95%CI:2.078-9.860;P<0.001),and patients with cholangitis(AOR=3.261;95%CI:1.204-8.832;P=0.020)were strongly associated with a higher rate of post-ERCP pancreatitis.CONCLUSION Advanced age has not been proved to be a risk factor for difficult cannulation,and secondary cannulation techniques can be safely and efficaciously utilized in this group.Patients with a Charlson Comorbidity Index≥2 and difficult cannulation are associated with an increased overall adverse events rate,while age≥80 years is not.

文摘BACKGROUND Pancreatic adenoma can potentially transform into adenocarcinoma, so it is recommended to be resected surgically or endoscopically. Endoscopic papillectomy is one of the main treatments for papillary adenoma, and bleeding, perforation, and pancreatitis are the most frequent and critical adverse events that restrict its wider use. There is no standard procedure for endoscopic papillectomy yet. The procedure is relevant to postoperative adverse events.AIM To reduce the postoperative adverse event rates and improve patients' postoperative condition, we developed a standard novel procedure for endoscopic papillectomy.METHODS The novel endoscopic papillectomy had two main modifications based on the conventional method: The isolation of bile from pancreatic juice with a bile duct stent and wound surface protection with metal clips and fibrin glue. We performed a single-center retrospective comparison study on the novel and conventional methods to examine the feasibility of the novel method for reducing postoperative adverse events.RESULTS A total of 76 patients, of whom 23 underwent the novel procedure and 53 underwent the conventional procedure, were retrospectively evaluated in this study. The postoperative bleeding and pancreatitis rates of the novel method were significantly lower than those of the conventional method(0 vs 20.75%, P = 0.028, and 17.4% vs 41.5%, P = 0.042, respectively). After applying the novel method, the most critical adverse event, perforation, was entirely prevented, compared to a prevalence of 5.66% with the conventional method. Several postoperative symptoms, including fever, rapid pulse, and decrease in hemoglobin level, were significantly less frequent in the novel group(P = 0.042, 0.049, and 0.014, respectively). Overall, the total adverse event rate of the novel method was lower(0 vs 24.5%, P = 0.007) than that of the conventional method.CONCLUSION Patients who underwent the novel procedure had lower postoperative adverse event rates. This study demonstrates the potential efficacy and safety of the novel endoscopic papillectomy in reducing postoperative adverse events.
文摘Immune checkpoint inhibitors(ICIs) targeting cytotoxic T-lymphocyte antigen 4 and programmed cell death protein 1 receptor/ligand have revolutionized cancer treatment, achieving unprecedented efficacy in numerous malignancies. Despite the excellent therapeutic effects of ICIs, medications, such as pembrolizumab, ipilimumab, nivolumab, atezolizumab, avelumab, and durvalumab, typically cause a broad spectrum of toxicity events termed as immune-related adverse events(ir AEs). Out of all ir AEs, ophthalmic adverse events occur infrequently and are not comprehensively recognized. The current understanding of ophthalmic ir AEs is mainly derived from case reports and case series. In this review, based on relevant articles in the literature and current evidence, we summarize the incidences, manifestations, diagnoses, underlying mechanisms, treatments, and outcomes of ophthalmic ir AEs and discuss possible management strategies. A better understanding of these features is critical for managing patients with ICI-associated ophthalmic adverse events.
文摘AIM: To evaluate the medical quality of ophthalmologic perioperative period during 2010-2012 in our hospital. METHODS: The relevant data of perioperative period were collected in our hospital during 2010-2012, and the medical quality of perioperative period was evaluated by using the traditional evaluation indexes and adverse events. Whereby, the traditional indicators include vision changes, improving of intraocular pressure, diagnostic accordance rate before and after operation, cure improvement rate, successful rescue rate, and incidence of surgical complications, etc Adverse events are associated with ophthalmologic perioperative events including pressure sores, postoperative wound infection, drug adverse events, and equipment related adverse events. RESULTS: There were 1483, 1662 and 1931 ophthalmic operations in our hospital in the year 2010, 2011 and 2012, respectively. From traditional index analysis, the proportions of vision improvement for each year were 96.43%, 96.76% and 97.32%, respectively; the rates of intraocular pressure improvement were 87.50%, 85.72% and 90.17%, respectively ( P <0.05); the diagnostic accordance rates before and after operation were 99.86%, 99.94% and 99.90%, respectively; cure improvement rates were 99.73%, 99.93% and 99.84%, respectively; the successful rescue rates were 82.98%, 81.46% and 76.66%, respectively; the complications incidence rates were 18.44%, 17.52% and 17.97%, respectively. The negative factor analysis results showed that: among all the patients of ophthalmic surgeries in our hospital during 2010 and 2012, only one case of postoperative wound infection was found in 2011, and also only one case of tumbling in 2010. The adverse drug events for each year were 1 case (0.07%), 2 cases (0.12%), and 4 cases (0.21%), respectively; the medical device adverse events for each year were 3 cases (0.20%), 5 cases (0.30%), and 6 cases (0.31%), respectively. Noticeably, only one case with postoperative infection of endophthalmitis was found in 2011. Moreover, no pulmonary infection or pulmonary embolism occurred during the three years. The perioperative adverse event rates for each year were 0.34% (5/1483), 0.48% (8/1662) and 0.52% (10/1931), respectively. Though incidence was rising during the three years, no statistical significance was observed (P>0.05). It is the same case with drugs and medical devices adverse events (P>0.05). CONCLUSION: Traditional indicators reflect an excellent operation of the perioperative ophthalmologic quality, whereas adverse events analysis indicates some underlying problems. Compared with the traditional indexes for medical quality evaluation, the index of adverse events is more reasonable and easier to make an objective evaluation for medical quality of ophthalmologic perioperation, facilitating further refine analysis. Reasonable application of the adverse events indicators helps hospital to make the detailed quality control measures.
文摘BACKGROUND Immune checkpoint inhibitors(ICPi)cause various immune-related adverse events(irAE)with thyroid dysfunction as a commonly reported abnormality.There is increasing evidence showing positive association with development of irAE and survival.However,prior trials with ICPi had underrepresentation of minorities with<5%African Americans.AIM To evaluate the association between development of irAE and survival outcomes among a racially diverse patient population.METHODS Data on patients with stage IV solid malignancies treated with programmed cell death-protein 1/programmed death ligand 1 blockers between January 2013 and December 2018 across MedStar Georgetown Cancer Institute facilities were retrospectively reviewed.Patients treated with cytotoxic T-lymphocyte-associated protein 4 inhibitors were excluded.Progression free survival(PFS)and overall survival(OS)were primary endpoints and were calculated using Kaplan-Meier methods and Wilcoxon rank sum test for comparison.RESULTS Out of 293 patients who met eligibility criteria,91 pts(31%)had any grade irAE;most common AE were endocrine(40.7%)specifically TSH elevation,dermatological(23.1%)and rheumatologic(18.7%).Proportion of irAE was significantly higher in Caucasians vs African Americans(60.4%vs 30.8%),in patients with low programmed death ligand 1,lower LDH,older age,and those who had more treatment cycles with ICPi.Rate of progression was lower in patients with irAE(30.8%vs 46.0%,P=0.0140).Median PFS(5.8 vs 3.0 mo,P=0.0204)and OS(17.1 vs 7.2 mo,P<0.0001)were higher with irAE.Statistically significant difference in OS(17.1 vs 8.6 mo,P=0.0002)but not in PFS(5.8 vs 3.3 mo,P=0.0545)was noted with endocrine irAE.No differences in survival were observed among other commonly reported irAE.Differences in survival among subgroups of patients with irAE are described.CONCLUSION Development of irAE positively correlated with improved PFS and OS as reported in previous studies.To our knowledge,this is the first study observing differences in OS favoring endocrine AE and Caucasian race.These factors may be potential surrogate markers of prognosis pending replication of these results in large-scale studies.
文摘AIM To evaluate the risk profile of sulfur hexafluoride in voiding urosonography(VUS) based on a large cohort of children.METHODS Since 2011 sulfur hexafluoride(SH,SonoV ue?,Bracco,Italy) is the only ultrasound contrast available in the European Union and its use in children has not been approved.Within a 4-year-period,531 children with suspected or proven vesicoureteral reflux(f/m = 478/53; mean age 4.9 years; 1 mo-25.2 years) following parental informed consent underwent VUS with administration of 2.6 ± 1.2 mL SH in a two-center study.A standardizedtelephone survey on adverse events was conducted three days later.RESULTS No acute adverse reactions were observed.The survey revealed subacute,mostly self-limited adverse events in 4.1%(22/531).The majority of observed adverse events(17/22) was not suspected to be caused by an allergic reaction: Five were related to catheter placement,three to reactivated urinary tract infections,five were associated with perineal disinfection before voiding urosonography or perineal dermatitis and four with a common cold.In five patients(0.9%) hints to a potential allergic cause were noted: Perineal urticaria was reported in three interviews and isolated,mild fever in two.These were minor self-limited adverse events with a subacute onset and no hospital admittance was necessary.Ninety-six point two percent of the parents would prefer future VUS examinations with use of SH.CONCLUSION No severe adverse events were observed and indications of self-limited minor allergic reactions related to intravesical administration of SH were reported in less than 1%.
