Cardiac implantable electronic device (CIED) is commonly used to treat arrhythmias. The amount of CIED implantation has increased year by year since its first application in 1958. At the same time, the CIED infection rate also increases significantly. Although the infection rate is very low for the primary implantation, the consequences of CIED infection are serious, and it is often necessary to remove the equipment for treatment. The mortality rate in patients with CIED infections is high, and the economic burden is huge. In this paper, the epidemiology, pathogenesis and pathogen, manifestations and diagnosis, risk factors, treatment and preventive measures of CIED infection were systematically described based on the recently published guidelines and international consensus literature, so as to provide theoretical guidance for the prevention of CIED infections.
ObjectiveThe risk factors of relapse in 133 epileptic children after withdrawal were analyzed retrospectively and provide reference for clinical withdrawal.MethodsFrom January 2017 to March 2019, 133 children with withdrawal epilepsy were selected as the study object. According to whether there was recurrence during the follow-up period, the children with epilepsy were divided into recurrence group (42 cases) and non recurrence group (91 cases). The gender, age of onset, history of trauma, frequency of seizure before treatment, EEG before drug reduction, imaging, type of medication, family history, time of reaching control, course of disease before treatment, comorbidity, multiple attack types, withdrawal speed and EEG before treatment were observed and compared between the two groups. ResultsThere were significant differences in EEG (χ2 =7.621), medication type (χ2=8.760), time to control (χ2=6.618), course before treatment (χ2=6.435), multiple seizure types (χ2=5.443) and epilepsy comorbidity (χ2=42.795) between the two groups (P < 0.05). The results of Logistic multiple regression analysis showed that the recurrence of epileptic children after drug reduction / withdrawal was correlated with abnormal EEG before drug reduction [OR=9.268, 95%CI (2.255, 38.092)], combined drug treatment [OR=3.205, 95%CI (1.159, 8.866)] and course of disease > 1 year before treatment [OR=5.363, 95%CI (1.781, 16.150)] (P < 0.05).ConclusionsIn order to reduce the possibility of recurrence of epileptic children, the treatment time of epileptic children with abnormal EEG, combined medication and long course before treatment should be prolonged properly.
ObjectiveTo explore the risk factors for accompanying depression in patients with community type Ⅱ diabetes and to construct their risk prediction model. MethodsA total of 269 patients with type Ⅱ diabetes accompanied with depression and 217 patients with simple type Ⅱ diabetes from three community health service centers in two streets of Pingshan District, Shenzhen from October 2021 to April 2022 were included. The risk factors were analyzed and screened out, and a logistic regression risk prediction model was constructed. The goodness of fit and prediction ability of the model were tested by the Hosmer-Lemeshow test and the receiver operating characteristic (ROC) curve. Finally, the model was verified. ResultsLogistic regression analysis showed that smoking, diabetes complications, physical function, psychological dimension, medical coping for face, and medical coping for avoidance were independent risk factors for depressive disorder in patients with type Ⅱ diabetes. Modeling group Hosmer-Lemeshow test P=0.345, the area under the ROC curve was 0.987, sensitivity was 95.2% and specificity was 98.6%. The area under the ROC curve was 0.945, sensitivity was 89.8%, specificity was 84.8%, and accuracy was 86.8%, showing the model predictive value. ConclusionThe risk prediction model of type Ⅱ diabetes patients with depressive disorder constructed in this study has good predictive and discriminating ability.
ObjectiveTo evaluate the methodological quality of cross-sectional surveys about Chinese medicine syndrome in a population at potential risk of cerebrovascular diseases. Methods The CNKI, WanFang Data, CBM and PubMed databases were electronically searched to collect cross-sectional surveys about Chinese medicine syndromes in a population at potential risk of cerebrovascular diseases from inception to December, 2022. The methodological quality was assessed using the JBI scale. Results A total of 105 studies were included. The average reporting rate of JBI was 52.06%, and the items with the highest scores included "sufficient coverage of the identified sample in data analysis" (100%), "description of study subjects and setting" (92.38%), and "using valid methods for the identification of the condition" (86.67%). Items with the lowest scores included "adequate sample size" (13.33%), "adequate response rate or low response rate managed appropriately" (14.29%), and "study participants recruited in an appropriate way" (20.95%). Subgroup analysis suggested that type of publication and number of implementation centers were potential factors influencing methodology quality (P<0.05). Conclusion The methods essential to a cross-sectional survey such as sampling, sample size calculation and handling with the response rate, and the syndrome diagnosis scales specific to Chinese medicine require further improvement.
ObjectiveTo evaluate the prevalence of obstructive sleep apnea hypopnea syndrome (OSAHS) in patients with asthma, and explore the association of OSAHS with asthma. MethodsPatients who were diagnosed as asthma between March 2014 and February 2015 were recruited in the study. They were categorized into an OSAHS group and a non-OSAHS group according to the Berlin questionnaire. The data of clinical characteristics and pulmonary function test were collected. Logistic regression analysis was performed to evaluate the factors associated with the incidence of OSAHS in asthma. ResultsA total of 64 patients with asthma were enrolled and 36 patients were complicated with OSAHS. The body mass index (BMI), allergic rhinitis history, inspiratory capacity, maximal mid-expiratory flow and provoking dose which make FEV1 reduce 20% were significantly different between two groups (all P < 0.05). Multivariate logistic regression analysis revealed that the increased BMI was an independent risk factor of OSAHS in patients with asthma. ConclusionThe occurrence of OSAHS with asthma is very high, and BMI may be an important associated risk factor.
Embolus occlusion in the retinal artery is the most common cause of central retinal artery occlusion (CRAO), while hypertension is the most common risk factor of CRAO, and ipsilateral carotid artery stenosis is the most significant risk factor in CRAO. Current clinical treatments include conservative treatments such as dilation of blood vessels and lowering the intraocular pressure (IOP), as well as aggressive treatments like intravenous thrombolysis and Nd:YAG laser. Both thrombolysis and Nd:YAG laser treatment can improve the visual acuity of CRAO patients, but because of its lack of randomized controlled trials, further clinical studies are needed to determine their efficacy and safety. CRAO patients may have vascular embolism at other sites in the body, and may cause different degrees of cardiovascular and cerebrovascular events. The probability of secondary ocular neovascularization following the occurrence of these events is 2.5% to 31.6%. In addition to eye care, clinicians should also focus more on preventing cardiovascular and cerebrovascular events, and focus on the screening and active treatment of systemic risk factors to reduce the incidence and mortality of cardiovascular and cerebrovascular events.
Objective To systematically review the risk factors for death in children with tuberculous meningitis (TBM). Methods The CNKI, VIP, WanFang Data, CBM, Cochrane Library, Web of Science, PubMed, EMbase and CINAHL databases were electronically searched to collect studies on the risk factors for death in children with TBM from inception to October 2022. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.3 software. Results A total of 15 studies involving 2 597 patients were included. The results of meta-analysis showed that male (OR=2.41, 95%CI 1.61 to 3.61, P<0.01), no history of BCG vaccination (OR=3.74, 95%CI 1.96 to 7.12, P<0.01), TBM stage (stage Ⅲ) (OR=2.04, 95%CI 1.26 to 3.28, P<0.01), HIV infection (OR=3.28, 95%CI 1.20 to 8.93, P=0.02), convulsion (OR=3.61, 95%CI 3.31 to 3.94, P<0.01), disturbance of consciousness (OR=3.58, 95%CI 2.40 to 5.34, P<0.01), cerebrospinal fluid protein concentration increased (OR=1.87, 95%CI 1.39 to 2.51, P<0.01), hydrocephalus (OR=2.44, 95%CI 1.60 to 3.71, P<0.01) and short hospitalization (OR=2.89, 95%CI 2.05 to 4.06, P<0.01) were risk factors for death in children with TBM. Under 5 years old, negative PPD skin test, positive meningeal irritation sign, malnutrition and history of contact with TB may not be associated with the death of TBM in children. Conclusion Male, no history of BCG vaccination, TBM stage (stage Ⅲ), HIV infection, convulsions, disturbance of consciousness, cerebrospinal fluid protein concentration increased, hydrocephalus and short hospitalization are risk factors for death in children with TBM. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo observe the children with idiopathic epilepsy who received AED therapy and seizure-free, withdrawal at least 1 year, and analyze the risk factors of seizure recurrence. In order to give better instructions for AED withdrawal of children with idiopathic epilepsy in pediatric department. MethodsChildren with idiopathic epilepsy who were seizure-free and had stopped AED treatment at least 1 year before the deadline of observation were collected from pediatric outpatient and inpatient department of the First Affiliated Hospital of Guangxi Medical University from January 2011 to January 2014. The following variables, derived from the case records were analyzed: sex, age at seizure onset, type of seizure, time period between the onset of the first seizure and start of treatment, number of seizures in the time period between the start of AED therapy and the last seizure, number of AEDs before remission, time period between the start of AED therapy and the last seizure, time period between the last seizure and withdrawal of AED treatment (seizure-free period, timing of AED withdrawal), time period between the start of AED withdrawal and total discontinuation(speed of withdrawal), EEG registered at the time of diagnosis, before AED withdrawal, during and after AED withdrawal, and the condition of recurrence, data analysed by multi-variate step-wise Cox regression model analysis. ResultsA total of 16(12.8%) children relapsed in a total number of 125 children with idiopathic epilepsy we collected; date evaluated by multi-variable analysis showed that the children suffering from seizure type of focal seizure, starting withdrawal after a seizure-free period of less than 3 years and with abnormal post-withdrawal EEG recording was associated with a higher risk of seizure recurrence. ConclusionsChildren with idiopathic epilepsy have a low risk of recurrence after AED withdrawal. Those who suffer from seizure type of focal seizure, start withdrawal after a seizure-free period of less than 3 years and with abnormal post-withdrawal EEG recording are associated with a higher risk of seizure recurrence.
Objective To define risk factors of nosocomical pneumonia (NP) in elderly in-patients. Methods Two hundred elderly in-patients were selected in the Geriatric Department of West China Hospital from January 1999 to June 2002. Among them, 100 patients developed NP during their hospital days and the others didn’t have the episodes of NP at the same time. The following factors were analyzed: sex, age, multiple underline diseases and their severity, smoking, activity of daily life, conscious status, aspiration, nasogastrial intubations, antibiotics use and hospitalization. SPSS 10.0 was used for Logistic regression analysis to determine the factors significantly associated with the development of NP. Results The following factors were significantly associated with the development of NP in the logistic regression analysis: aspiration [OR 28.452, 95%CI (3.793 to 213.447)],multiple diseases [OR 17.157, 95%CI (2.734 to 107.651)], multiple antibiotics use [OR 6.396, 95%CI (1.861 to 21.980)], smoking [OR 1.774, 95%CI (1.211 to 2.600)] and prolonged hospitalization [OR 1.134, 95%CI (1.081 to 1.189)]. Conclusions Aspiration, multiple diseases, multiple antitiotics use, smoking and prolonged hospitalization are closely related to NP in elderly in-patients. Cautionary medical measures and shortening hospitalization were the key factors to decrease the incidence of NP for the patients in Geriatric Department.
Objective To investigate the values of cytokines in evaluating the severity and prognosis of patients with coronavirus disease 2019 (COVID-19). Methods A total of 205 COVID-19 patients in Wuhan Leishenshan Hospital were retrospectively analyzed. According to the severity of the disease, patients were divided into common group (n=117), severe group (n=69) and critical group (n=19). The patients’ basic condition and cytokine related parameters were collected, the differences between the three groups were compared and their values in assessing the severity and prognosis of COVID-19 patients were analyzed. Results There were statistically significant differences in the age, severe acute respiratory syndrome coronavirus 2 nucleic acid test results, interleukin (IL)-6, IL-10, IL-2 receptor, IL-8, and tumor necrosis factor-α among the three groups of patients (P<0.05). Correlation analysis showed that the age, severe acute respiratory syndrome coronavirus 2 nucleic acid test continued to be positive for 20 days, IL-6 level, IL-10 level, IL-2 receptors level, IL-8 level and tumor necrosis factor-α level were related to the classification of COVID-19. The correlation coefficient rs was 0.354, 0.187, 0.366, 0.327, 0.329, 0.273 and 0.157, respectively (P<0.05). The levels of IL-6, IL-10, IL-2 receptor, IL-8, and tumor necrosis factor-α in dead patients with COVID-19 were higher than those in surviving patients (P<0.05). Multivariate analysis showed that age [odds ratio (OR)=1.034, 95% confidence interval (CI) (1.006, 1.063), P=0.016], IL-6 level [OR=1.030, 95%CI (1.006, 1.055), P=0.015], IL-10 level [OR=1.088, 95%CI (1.003, 1.179), P=0.042] and IL-2 receptor level [OR=1.003, 95%CI (1.001, 1.005), P=0.001] were independent risk factors for common COVID-19 to become severe or critical. Conclusion The levels of cytokines in COVID-19 patients are closely related to the severity and prognosis of the disease.
