  • Efficacy and long-term retention rate comparision of ketogenic diet (KD) for children with intractable epilepsy in outpatient department and inpatient department

    ObjectiveTo compare the efficacy and compliance of children children with refractory epilepsy receiving ketogenic diet (KD) in outpatient department with children receiving KD treatment in inpatient department. MethodsA retrospective study of 44 children with intractable epilepsy receiving the modified classical ketogenic diets in outpatient department from June 2014 to December 2015, who were followed-up during the third, sixth and twelfth month. Records of epileptic seizures and adverse reactions were used to evaluate the efficacy and retention rate of inpatient department KD treatment in children with refractory epilepsy, and compared with 104 children receiving KD treatment in inpatient department at the same period. ResultsThirty-four of the forty-four children comleted observation after 12-month follow-up, 15 cases had been seizure freedom, 22 cases had more than 50% reduction in seizure frequency, 12 patients had less than 50% reduction in seizure frequency.The total effective rate of the KD therapy in outpatient department was 64.7%, and the retention rate was 71%. 18 of of the 104 children with KD treatment in inpatient department at the same period comleted observation after 12-month follow-up, 3 cases had been seizure freedom, 5 cases had more than 50% reduction in seizure frequency, 13 cases had less than 50% reduction in seizure frequency.The total effective rate of the KD therapy in inpatient department was 27.8%, and the retention rate was 17.3%. ConclusionThe KD therapy in outpatient department is effective to children with intractable epilepsy, and there is a highly efficacy and compliance of children receiving KD in outpatient department comparing with children receiving KD in inpatient department. Therefore, it's optional to children with refractory epilepsy who can't received KD by inpatient department because of insufficient number of beds.

  • Retention rate of Oxcabazepine in children under the age of four with symptomatic epilepsy

    ObjectiveTo investigate the long-term retention rate of Oxcabazepine (OXC) in Chinese young children with symptomatic epilepsy and to evaluate the withdrawal causes of OXC. MethodsClinical features of 89 cases (male/female:48/41) from January.2009 to June.2015 were collected. Patients with symptomatic epilepsy who received mono-or adjunctive therapy with OXC. The initial dose was 10mg/kg/d twice a daily, 3~4weeks to increased to the target dose. OXC doses ranged between 12~53 mg/(kg·d) (mean dose:34.0±8.59 mg/(kg·d). An investigator recorded the antiepileptic drugs, seizure frequency, electroencephalogram and side effects for 3, 6, 12, 24 and 36months during follow-up. ResultsA total of 89 patients were enrolled in this investigation. patients with 50% reduction in seizure frequency in 6, 12, 24 and 36 months were 56.5%, 55.3%, 44.7%, 24.7%, and with seizure-free were 36.5%, 34.1%, 29.4%, 16.5%. In this research, 16(18.0%) patients experienced at least one side effect. The most common side effects observed were drowsiness 8 (42.1%), rash 3 (15.8%), and most were mild in severity. The retention rate of OXC in 3, 6, 12, 24, and 36months were 95.5%, 87.6%, 75.3%, 56.2%, 25.8%, respectively. The predominant causes of withdrawal were lack of efficacy 36(54.5%), end point 10(15.2%), adverse effects 8(12.1%), seizure-free 5(7.6%), follow-up loss 3(4.5%). COX analysis reveals that the age of onset was associated with treatment failure. ConclusionOur study demonstrates that OXC is safe and well tolerated in infants and very young children with symptomatic epilepsy, but the long-term retention rate is low. Whereas, for the purpose of better retention rate and therapeutic benefits, we should treat discretely depending on the complicated etiology and clinical features.

  • Construction and verification of a long-term survival prediction model for rectal cancer-Nomogram

    ObjectiveBased on a large sample of data, study the factors affecting the survival and prognosis of patients with rectal cancer and construct a prediction model for the survival and prognosis.MethodsThe clinical data of 26 028 patients with rectal cancer were screened from the Surveillance, Epidemiology, and End Results (SEER) clinical database of the National Cancer Institute. Univariate and multivariate Cox proportional hazard regression analysis were used to screen related risk factors. Finally, the Nomogram prediction model was summarized and its accuracy was verified.ResultsResult of multivariate Cox proportional hazard regression analysis showed that the risk factors affecting the survival probability of rectal cancer included: age, gender, marital status, TMN staging, T staging, tumor size, degree of tissue differentiation, total number of lymph nodes removed, positive lymph node ratio, radiotherapy, and chemotherapy (P<0.05). Then we further built the Nomogram prediction model. The C index of the training cohort and the validation cohort were 0.764 and 0.770, respectively. The area under the ROC curve (0.777 and 0.762) for 3 years and 5 years, and the calibration curves of internal and external validation all indicated that the model could effectively predict the survival probability of rectal cancer.ConclusionThe constructed Nomogram model can predict the survival probability of rectal cancer, and has clinical guiding significance for the prognostic intervention of rectal cancer.

  • Purchase willingness rate of long-term care insurance in China: a meta-analysis

    ObjectiveTo systematically review the purchase willingness rate and influencing factors of long-term care insurance in Chinese population.MethodsCNKI, VIP, WanFang Data, EMbase and PubMed databases were electronically searched to collect cross-sectional studies on the purchase willingness rate of long-term care insurance in China from inception to March 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using Stata 16.0 software.ResultsA total of 66 cross-sectional studies involving 151 231 subjects were included. The results of the meta-analysis showed that the purchase willingness rate of long-term care insurance in China was 52.4% (95%CI 48.1% to 56.8%). Subgroup analysis showed that: among the sample characteristic factors, residents who were from the central region of China (56.4%), being studied after 2016 (53.3%), and residing in pilot regions (53.1%) had a higher willingness rate to purchase long-term care insurance. Among demographic factors, the research considered factors of residence and family size (56.2%) contributed to a higher willingness to purchase long-term care insurance, and residents with monthly income from 1 000 yuan to 5 000 yuan (55.4%) and who were unmarried (55.3%) had a higher willingness to purchase long-term care insurance. Among health and concept factors, the research considered factors of insurance and government trust (57.3%), factor of number of chronic diseases (55.0%), and factor of health risk cognition (52.4%) contributed to a higher willingness to purchase long-term care insurance. Among the factors of long-term care insurance system, factor of the government subsidy (60.6%), factor of long-term care insurance price (58.0%) and factor of payment methods (56.2%) contributed a higher willingness to purchase long-term care insurance.ConclusionsCurrent evidence shows that over half of residents are willing to purchase long-term care insurance. However, different factors still affect their purchase willingness. The influencing factors reflect numerous difficulties in the current long-term care insurance system, which requires attention and continuous improvement of policy formulators and related researchers.

  • Effect of Releasable Sutures on Trabeculectomy: A Meta-Analysis

    Objective To evaluate the effect of releasable sutures on shallow anterior chamber, filtering bleb and long-term intraocular pressure (IOP). Methods We searched MEDLINE (1971 to 2007), OVID (1971 to 2007) and National Science and Technology Library (1971 to 2007). Randomized controlled trials (RCTs) of the effect of releasable sutures on trabeculectomy were collected. Study selection and assessment, data collection and analyses were undertaken and cross-checked by two reviewers. Meta-analyses were performed with The Cochrane Collaboration’s RevMan 4.2.10 software. Results Six RCTs involving 341 eyes were included. Significant differences were observed in the reduction of postoperative shallow anterior chamber (RD –0.23, 95%CI –0.31 to –0.14, Plt;0.000 01) and functional filtering blebs (RD –0.15, 95%CI –0.27 to –0.02, P=0.02). But, no differences were observed for the control of long-term IOP (SMD –0.13, 95%CI –0.37 to 0.10, P=0.27). Conclusion The evidence currently available showed that releasable sutures could reduce the incidence of shallow anterior chamber and has no beneficial effect in controlling long-term IOP. The current evidence is insufficient to define the efficacy of maintaining functional filtering blebs. Further large-scale, high-quality randomized controlled trials are needed.

  • Ⅲ期临床试验非盲延期阶段联合使用吡仑帕奈的局灶性癫痫患者的四年药物安全性、耐受性及发作结局:307 号研究

    评估 307 号研究(临床试验验证码:NCT00735397)Ⅲ期非盲延期阶段(OLEx)联合使用吡仑帕奈的局灶性癫痫患者的药物安全性、耐受性及痫性发作结局。患者在完成任一 III 期双盲试验后均可进入非盲延期阶段(Open-labelextension,OLEx)。对所有 OLEx 队列中有同样最小吡伦帕奈暴露剂量的局灶性癫痫和继发全面性癫痫(Secondarily generalized seizures,SGS)的患者进行药物安全性及耐受性和痫性发作结局(每 28 d 中位痫性发作减少率、反应率和无发作率)的分析。另外,针对 OLEx 的早期失访进行了额外的敏感性分析。从 1 480 例双盲试验中随机分组的患者共纳入 1 218 例。大部分患者(65.4%~80.9%)仅用吡仑帕奈 12 mg,每日一次,进行治疗,并在相同剂量下完成长期的检测,或是相对基线联合使用少量抗癫痫药物(AEDs)。长期的药物安全性及耐受性结果与双盲研究一致。导致超过 1% 的患者研究中断治疗的紧急不良反应事件(Treatment-emergent adverse events,TEAEs)包括眩晕、易激、疲劳。有临床意义的 TEAEs 稳定期为 4 年。所有队列中患者的痫性发作结局随时间持续改善。对于接受 3 年(n = 436)、4 年(n = 78)药物治疗的患者 28 d 中位痫性发作减少率分别为 62%、70.6%,相应的 50% 反应率为 59.6%、67.9%。最大 28 d 中位痫性发作减少率发生于基线水平的 SGS 患者,接受 3 年(n = 190)、4 年(n = 28)药物治疗分别为 88.0% 和 100.0%。在这些队列中分别有 40.0% 和 53.6% 的患者达到了无 SGS。排除早期失访后的 28 d 中位痫性发作减少率结果类似。长期吡仑帕奈联合用药(≤4 年)不会导致新的药物安全性及耐受性问题,并且可以很大程度地减少痫性发作,特别是基线水平的 SGS 患者。

  • Prognostic Factors of Severe Chronic Obstructive Pulmonary Disease in Elderly Patients:A Long-term Follow-up Study

    Objective To investigate the prognostic factors of severe chronic obstructive pulmonary disease ( COPD) in elderly patients, and to guide the clinical assessment and appropriate interventions. Methods A prospective cohort study was carried out from May 1993 to December 2010. A total of 178 elderly patients with severe COPD were recruited for baseline survey, and followed up for the living conditions, whether used non-invasive ventilation, and causes of death. A survival analysis was performed on all patients stratified by lung function. The significant factors on survival rate were analyzed. Results In this cohort the survival rates were 49% and 12% in five and ten years, respectively. The important factors for prognosis were age [ relative risk( RR) = 1. 043, 95% confidence intervals( 95% CI = 1. 010-1. 050] , forced expired volume in one second ( FEV1 , RR = 0. 019, 95% CI = 0. 007-0. 052) , FEV1% pred ( RR = 1. 045, 95% CI = 1. 012-1. 079) , lung function grade ( RR = 2. 542, 95% CI = 1. 310-4. 931) , body mass index ( BMI, RR= 0. 945, 95% CI = 0. 895-0. 952) , and pulmonary heart disease ( RR = 1. 872, 95% CI = 1. 188- 2. 959) . In severe COPD, non-invasive ventilation ( NIV, RR = 1. 167, 95% CI = 0. 041-1. 674) , pulmonary heart disease ( RR = 3. 805, 95% CI = 1. 336-10. 836) , FEV1 ( RR = 0. 081, 95% CI = 1. 001-1. 168) , and arterial partial of oxygen ( PaO2 , RR=0. 956, 95% CI =0. 920-0. 993) were the independent predictors.The patients using NIV had longer survival than those without NIV. The 5 and 10 years survival rate in the patients with NIV were 78% and 50% , much higher than those without ventilation which were 30% and 25% , respectively. In extremely severe COPD, FEV1 ( RR=1. 059, 95% CI =1. 015-1. 105) , arterial partial of carbon dioxide ( PaCO2 , RR=1. 037, 95% CI = 1. 001-1. 074) , age ( RR= 1. 054, 95% CI = 1. 013-1. 096) and pulmonary heart disease ( RR = 1. 892, 95% CI = 1. 125-3. 181) were the independent predictors. Conclusions Age, BMI, FEV1 , PaO2 , PaCO2 , pulmonary heart disease, and NIV were prognostic factors in elderly patients with severe COPD. The prognostic factors between severe and extremely severe COPD were not identical. Patients with severe COPD should be given early intervention, including progressive nutritional support, and long-term home oxygen therapy combining with NIV.

  • Daytime Risk Factors of Nocturnal Hyoxemia in COPD Patients Unqualified for Long-term Oxygen Therapy

    Objective To explore the daytime variables which are predictive to nocturnal hyoxemia among COPD patients unqualified for long-term oxygen therapy ( LTOT) . Methods Forty-eight stable COPD patients with SaO2≥90% were enrolled in this study and regarded as patients unqualified for LTOT. All patients underwent lung function examination during daytime. Their nocturnal oxygen saturation was monitored with overnight pulse oximetry ( OPO) . ResultsDaytime oxygen saturation was positively correlated with nocturnal mean SaO2 ( r =0. 79, P lt;0. 0001) , and negatively correlated with time spend with saturation below 90% ( TB90) ( r = - 0. 75, P lt; 0. 0001) . No significant relationship was found between lung function parameters and nocturnal SaO2 . The patients with daytime oxygen saturation between 90% and 95% were more likely to have lower nocturnal oxygen saturation and longer TB90 ( P lt;0. 05) .Conclusions Daytime oxygen saturation may effectively predict the occurrence of nocturnal hyoxemia in stable COPD patients unqualified for LTOT. To reduce COPD complications and improve prognosis, we suggest a relative indication of LTOT for patients with daytime oxygen saturation between 90% and 95% and with nocturnal hyoxemia.
