Based on literatures on Meta-analysis and randomized controlled trial, drug use and some geriatrics syndromes such as cognitive impairment and depression, in elderly diabetic patients were reviewed. Insulin plus oral hypoglycemic drugs was more rational therapy for insulin resistance and islet dysfunction in type 2 diabetes mellitus. We should pay more attention to cognitive impairment and depression in elderly type 2 diabetic patients.
General practice is a new discipline, and it is in common with evidence-based medicine for the features of “patient-centered” and “evidence-based”. Evidence-based medicine has spread in all fields of clinical practice, and it has been applied to different extents in many medical health and medical education fields including general practice. This paper aims to discuss and analyze the significance, modes and attentions of evidence-based general practice, so as to provide further references for promoting the practice of evidence-based general practice in China.
Objective To formulate an evidence-based treatment for a patient with pulmonary tuberculosis combined with tuberculous meningitis and tuberculous pericarditis. Methods According to the principles of evidencebased clinical practice, we searched The Cochrane Library (Issue 2, 2008), Ovid-Reviews (1991 to 2008), MEDLINE (1950 to 2008), and http://www.guideline.org. to identify the best evidence for treating a patient with pulmonary tuberculosis combined with tuberculous meningitis and tuberculous pericarditis. Results Nine guidelines, 2 systematic reviews, and 11 randomized controlled trials were included. The evidence showed that corticosteroids could help reduce the risk of death and disabling residual neurological deficiencies in patients with tuberculous meningitis. After adjusting for age and gender, the overall death rate of patients with tuberculous pericarditis was significantly reduced by prednisolone (P=0.044), as well as the risk of death from pericarditis (P=0.004). But for patients with pulmonary tuberculosis, there was still a controversy about the use of corticosteroids. Given the evidence, the patient’s clinical conditions, and his preferences, dexamethasone was used for the boy in question. After 7 weeks of treatment, his cerebrospinal fluid returned to normal and pericardial effusion disappeared. Conclusion Corticosteroids should be recommended in HIV-negative people with tuberculous meningitis or/and tuberculous pericarditis. The difference in the effectiveness of various corticosteroids such as dexamethasone, prednisolone, or methylprednisolone and the optimal duration of corticosteroid therapy is still unknown.
Objective Through studying a diabetic patient accompanied with pancreatic cancer by means of evidence-based clinical practice, to find out the relationship between diabetes mellitus and cancer and whether the long-acting insulin glargine increases the risk of cancer or not, which is regarded as a disputable hot issue at present. Methods Such databases as The Cochrane Library (Issue 3, 2010), OVID-EBM Reviews (1991 to Sept. 2010), MEDLINE (1950 to Sept. 2010) and CNKI (2000 to Sept. 2010) were retrieved to collect high quality clinical evidence, and the best therapy was formulated in accordance with the willingness of patients themselves. Results Eight randomized controlled trials (RCTs), four meta-analyses and one RCT meta-analysis were included. The evidence indicated that: a) Diabetes mellitus was kind of related to the occurrence of malignancies; b) There was no evidence at present showing the relationship between long-acting insulin glargine and cancer; c) Strictly controlling of blood sugar did not increase the risk of tumorigenesis, but hyperglycemia causing cancer was proofless; and d) Whether the diabetic patient with cancer should stop taking long-acting insulin glargine or not should require suggestions from specialists rather than patients themselves. Conclusion No evidence at present shows that tumorigenesis is related to diabetes mellitus, long-acting insulin glargine and strict controlling of blood sugar. It is necessary to require more evidence to decide whether the therapy should be adjusted or not for the diabetic patient with cancer who is in the process of glargine therapy.
Objective Methods of evidence-based medicine were used to make an individulized treatment plan concerning newly diagnosed type 2 diabetes mellitus in elderly patients. Method After clinical problems were put forward, evidence was collected from third issue, 2003, Cochrane Library, Medline (PubMed 1990.1-2003.2) and http:// sumsearch.uthscsa.edu/ searchform4.htm according to the search strategy. Subject words were: diabetes mellitus non-insulin-dependent; self-monitor of blood glucose; micro-and macro-vascular complications; sulphonylureas; insulin ; aspirin; metformin; acarbose; self-monitor of blood glucose; older patient; hypertension management; Lipid management; RCT; human; meta-analysis；systmatic review. Results A total of 112 RCTs, and 24 systematic reviews were identified. A rational treatment plan was made upon a serious evaluation of the data. After one year follow-up, the plan was proved optimal. Conclusions The treatment efficacy in newly diagnosed type 2 diabetes mellitus in the elderly has been improved by determining an individulized treatment plan according to evidence-based methods.
Little has been reported about deep venous thrombosis (DVT) that occurs after the implantation of the cardiac pacemaker. DVT affects the prognosis and quality of life of patients severely, or even causes fatal pulmonary embolism. Research on its risk factors, therapeutic strategy and secondary prevention does not coincide with one another. We have searched the systematic reviews and randomized controlled trials of DVT through PubMed, Cochrane Library and Guideline. Evidence has showed that previous DVT, over 40 years of age, and surgical history are the major risk factors. Initial treatment of DVT with heparin and maintenance therapy with oral anticoagulant are indispensable and effective, and could improve the prognosis of patients. If patients with previous DVT are at increased risk in the future, heparin and / or oral anticoagulant application may be used for prophylaxis.
【摘要】 目的 老年综合评估法筛查75岁以上2型糖尿病（type 2 diabetes mellitus，T2DM）合并老年综合征的情况，并观察以甘精胰岛素为基础的治疗方法对老年综合征、血糖、低血糖事件、治疗满意度等的影响。 方法 应用老年综合评估中的日常生活能力、工具性日程生活能力、简易智能量表、老年抑郁量表、微型营养评定法，分别评估2005年12月—2009年12月老年门诊及病房住院的日常生活能力、认知功能状态、情绪障碍和营养状态，对其合并功能障碍、痴呆、抑郁、营养障碍、伤害性跌倒等老年综合征的患病情况进行横断面调查；筛选至少合并一种老年综合征和一个其他合并疾病，血糖控制差、预期寿命有限的患者进行以甘精胰岛素为基础的降糖治疗，采用自身前后对照的方法了解对糖化血红蛋白（hemoglobin A1c， HbA1c）、低血糖事件、治疗满意度的影响，并观察甘精胰岛素治疗方案对上述老年综合征的影响。 结果 132例老年门诊及病房住院的75岁以上T2DM患者功能障碍者高达50.0%（66例），罹患包括轻度认知功能障碍在内的痴呆比例为39.4%（52例）；合并抑郁症28.0%（37例）；营养失衡30.0%（39例）。33例患者符合甘精胰岛素治疗纳入标准，经过2年的随访发现，以甘精胰岛素为基础的治疗方案在适当降低HbA1c水平时，不增加老年综合征的患病率，但可以减少胰岛素多次皮下注射的次数，降低低血糖事件发生次数（由1.58次/例降为0.81次/例），提高患者治疗满意度。 结论 75岁以上T2DM患者合并老年综合征的比例高，老年综合评估能及时发现老年综合征；以甘精胰岛素为基础的治疗方案不增加老年综合征的发生，并能显著降低低血糖事件数、改善营养状态、提高患者对治疗的满意度。【Abstract】 Objective To screen geriatric syndrome in patients older than 75 years with type 2 diabetes mellitus (T2DM) by the method of comprehensive geriatric assessment, and observe the impact of glargin-based therapy on geriatric syndrome, blood glucose level, the event of hypoglycemia and treatment satisfaction degree in patients older than 75 years with T2DM who suffered at least one kind of Geriatric syndromes. Methods From December 2005 to December 2009, activity of daily living (ADL), instrument activity of daily living (IADL), mini-mental state examination, geriatric depression scale and mini-nutritional assessment in comprehensive geriatric assessment were used to assess daily living ability, cognitive function status, emotional disorder and nutritional status of out/in-patients older than 75 years with T2DM in the Department of Geriatrics. Cross-sectional study was carried out to investigate geriatric syndromes such as combined functional disorder, dementia, depression, nutritional disorder and impairment falls in those patients, and patients with T2DM combined with at least one kind of geriatric syndrome and another kind of combined disease were screened out. A glargin-based anti-hyperglycemic therapy was carried out for those patients with poor blood glucose control limited remaining life time. The effects of this therapy on hemoglobin A1c (HbA1c), the event of hypoglycemia and treatment satisfaction degree of the patients were studied through a self-comparison method. Then, its effect on the above-mentioned geriatric syndromes was observed. Results Among all the 132 out/in patients older than 75 years with T2DM, the prevalence rates of functional disorder (including ADL and IADL), dementia including mild cognitive disorder, depression, and malnutrition were respectively 50.0% (66), 39.4% (52), 28.0% (37), and 30.0% (39). Only 33 patients met the criteria of glargin-based treatment. After 2 years of follow-up, we found that the glargin-based treatment could properly decrease the level of HbA1c without increasing the prevalence rate of geriatric syndrome. Moreover, it could reduce the frequency of insulin injection and the events of hypoglycemia, and treatment satisfaction degree was also significantly improved. Conclusions Geriatric syndrome has a relatively high prevalence rate in patients older than 75 years with T2DM. Comprehensive geriatric assessment is beneficial in finding out the geriatric syndrome, and glargin-based hypoglycemic therapy can significantly reduce the events of hypoglycemia, improve nutritional status, and increase treatment satisfaction degree without increasing the rate of geriatric syndrome .
Frailty and cognitive impairment are two major risk factors for adverse outcomes in elderly patients with diabetes. In the elderly, physical frailty and cognitive impairment frequently coexist, and have similar pathophysiological pathways, so the new concept of " cognitive debilitation” has been proposed. Physical frailty and cognitive impairment could accelerate the decline of function among elderly diabetic patients, and seriously affect their quality of life. Early identification and appropriate intervention of cognitive frailty may improve the adverse outcomes of elderly patients with diabetes. This article reviews the research progress of cognitive frailty and senile diabetes.
Objective To apply the evidence-based treatment method to direct the clinical therapy of refractory chronic lymphocytic leukemia (CLL). Methods Such evidence-based medicine databases as The Cochrane Library (Issue 10, 2010), OVID database, PubMed (January 1992 to October 2010) and http://www.nccn.org/ were searched to find the clinical evidence with high quality and the optimum treatment was designed based on the patient’s preferences. Results Two RCTs and five CCTs were included. The available clinical evidence displayed that rituximab could improve the therapeutic effect of combined chemotherapy on the refractory CLL, the COP/CHOP regimens were effective for the fludarabine-resistant CLL, and hematopoietic stem cell transplantation could be an effective salvage therapy for the relapsed/refractory CLL, but not the first-line recommendation drug. This patient was treated by CHOP regimen combined with rituximab, the condition of disease was improved two months after stopping chemotherapy, and the follow-up was conducted. Conclusion Current evidence reveals that rituximab combined with CHOP regimen produces good tolerance with a better clinical outcome than that of CHOP regimen. Clinical practice results display that the combination of rituximab and CHOP regimen can bring good prognosis to the patient, but still needs high-quality evidence to prove．
ObjectiveTo investigate the clinical electrophysiological characteristics of Cyclin-dependent kinase-like 5 gene induced developmental epileptic encephalopathy (CDKL5-DEE). MethodsThe clinical data and series of video EEGs of children with CDKL5-associated developmental epileptic encephalopathy (CDKL5-DEE) who were admitted to the Children’s Medical Center of Peking University First Hospital from June 2016 to May 2024 were retrospectively analyzed. Results A total of 16 patients with CDKL5-DEE were enrolled, including 13 females and 3 males. All patients had de novo variants of CDKL5 gene, including 6 cases of missense variants, 5 cases of frameshift variants, 4 cases of nonsense variants, and 1 case of large fragment deletion. The age of onset was 8 days (d) after birth ~1 year (y) and 10 months (m), and the median age was (85.94±95.76) days. Types of seizures at onset: 4 cases of tonic seizures [age of onset 10~52 days, median age (25.5±15.84) days]; There were 5 cases of focal seizures [age of onset 8 d~8 m, median age (77.76±85.97) d]. There were 4 cases of epileptic spasmodic seizures [age of onset 3 m~1 y 10 m, median age (6.25±3.49) m]; There were 2 cases of bilateral tonic-clonic seizures [age of onset 30~40 days, median age (35.00±5.00) days]; focal concurrent epileptic spasm seizures 1 case (age of onset 2 m). A total of 59 VEEG sessions were performed in the pediatric EEG room of Peking University First Hospital for 4 hours. All the results were abnormal, including 26 normal background, 25 slow rhythm difference with background, and 8 no background. The interictal was 16 posterior or focal discharges, 19 multifocal discharges, 17 generalized or accompanied by focal/multifocal discharges, and 7 hypsarrhythmia; The ictal was 33 epileptic seizures, 6 myoclonic seizures, 5 focal seizures, 2 tonic-clonic seizures, 2 atypical absence seizures, 2 tonic seizures, 1 myoclonic sequential focal seizure, 1 focal sequential epileptic spasm, and 1 hypermotor-tonic-spasms. The background of patients within 6 months of age was normal, and the background abnormality increased significantly with age. generalized discharges are evident after 2 years of age between seizures. Conclusion CDKL5-DEE seizures have an early onset and are refractory to medications. Epileptic spasms are the most common type of seizure in every patient and long-lasting, with generalized seizures increasing markedly with age. EEG is characterized by a normal background within 6 months. With the increase of age, the background and interictal discharges have a tendency to deteriorate.
