ABSTRACT
Objective:To explore the application value of next-generation sequencing (mNGS) technology in patients with Herpes simplex pneumonia mixed infection.Methods:The clinical data of pneumonia patients who underwent alveolar lavage fluid mNGS technology and traditional pathogen detection in the Affiliated Hospital of Yangzhou University from June 2018 to January 2021 were retrospectively collected.Results:A total of 41 patients with mNGS Herpes simplex type 1 (HSV-1) test (4 HSV-1 carriers, 37 HSV-1 infections) were enrolled in this study, including 22 males and 19 females. The age ranged from 46 to 83 years old, with a median age of 67 years. The higher proportion of pathogens in 25 cases of HSV-1 co-infection detected by mNGS were Pneumocystis jiroveci (6 cases, 24.0%), Acinetobacter baumannii (4 cases, 16.0%), and Klebsiella pneumoniae (4 cases, 16.0%), and Aspergillus fumigatus (3 cases, 12.0%). The difference in the Simpson's diversity index in the HSV-1carrier group, HSV-1 single infection group and HSV-1 mixed infection group was statistically significant ( P<0.05). Compared with 12 cases of HSV-1 single infection, the time for body temperature to return to normal for 25 cases of HSV-1 mixed infection was [(5.16±2.04)days vs (3.75±1.29)days], and course of antibiotic treatment was longer [(10.60±2.18)d vs (8.92±1.98)d]. Conclusions:The mNGS technology has obvious advantages in identifying HSV-1 mixed infections, which is beneficial to physicians to treat them accurately.
ABSTRACT
Antiepileptic drugs (AEDs) are the main treatments of epilepsy, but their use is usually limited by adverse reactions, among them psychiatric and behavioral ones including aggressive behavior. Levetiracetam , perampanel, and topiramate , which have diverse mechanisms of action, have been associated with aggressive behavior. 5-HT and γ-aminobutyric acid (GABA), especially glutamate [via α-amino-3-hydroxy-5-methyl-4-isoxazole-propionate receptor (AMPA) receptor] seem to play key roles. Other mechanisms involve hormones, epigenetics and alternative psychosis. Neurological and/or mental health disorders tend to increase aggressive behavior sensitivity. The adverse reactions caused by AEDs are getting more and more attention. Clinicians may identify and manage this side effect as early as possible, if the risk factors and underlying mechanisms of aggressive behavior induced by antiepileptic we find. This article will explain the possible mechanisms.
ABSTRACT
Objective:To evaluate the application value of metagenomic next-generation sequencing(mNGS) for patients with severe pneumonia of unknown pathogen.Methods:The clinical data of 8 patients with unknown pneumonia pathogens who were assisted by the alveolar lavage fluid mNGS technology treated in Affiliated Hospital of Yangzhou University from June 2019 to February 2020 were retrospectively analyzed, including alveolar lavage fluid smear, culture, and the sequencing result.The clinical characteristics and mNGS detection results were comprehensively analyzed.According to the results of mNGS and the judgment of the clinician, the patients were divided into confirmed pathogens group and undetermined pathogens group, and the Simpson's diversity index of two groups was compared.Results:Among 8 cases, there were 5 males and 3 females, and the median age was 62.5 years (ranged from 41 to 71 years). All of them had chronic diseases except 1 case, including diabetes, chronic obstructive pulmonary disease and kidney transplantation.mNGS was positive in 8 patients, and conventional test was positive in 3 patients.The comparison of the Simpson's diversity index between the identified pathogenic group and the undetermined pathogenic group showed statistically significant difference [(0.398 ± 0.222) vs.(0.763 ± 0.061), t=2.709, P=0.035]. The positive results of mNGS were different from that of conventional test in 2 patients.The nucleic acid number in 3 cases of Pneumocystis carinii with mNGS positive results ranged from 120 to 15 580, with genomic coverage rates from 24.6% to 99.8%. Conclusion:mNGS can help physicians acquire information of the pathogenic bacteria quickly and comprehensively, especially for patients with unknown pneumonia pathogenic bacteria.
ABSTRACT
Objective To analyze the risk factors of hemorrhage after thrombolysis for mild cerebral infarction and the curative effect of low-dose alteplase.Methods 375 patients with mild cerebral infarction whose onset time was less than 4.5 hours from January 2013 to May 2017 in our hospital were selected as the research objects.Those undergoing low-dose alteplase thrombolysis were included in the thrombolysis group (n =195) while those without thrombolysis were included in the non-thrombolysis group (n =180).The therapeutic effects were analyzed.Patients with intracerebral hemorrhage in the thrombolysis group at 14 days after thrombolysis were included in the observation group while those without hemorrhage were included in the control group.Related data were compared between the two groups.The single factors and independent risk factors of hemorrhage after thrombolysis in patients with mild cerebral infarction were analyzed.Results National Institute of Health Stroke Scale (NIHSS) scores of the thrombolysis group at 1 week,1 month and 3 months after treatment were significantly lower than those of the non-thrombolysis group (P ＜0.05).Serum neuron specific enolase (NSE) and C-reactive protein (CRP) levels in the thrombolysis group were lower than those in the non-thrombolysis group after treatment (P ＜ 0.05).The prognosis of the thrombolysis group was better than that of the non-thrombolysis group after treatment (P ＜ 0.05).In this study,30 patients undergoing thrombolysis had intracerebral hemorrhage within 14 days after thrombolysis,and the incidence of intracranial hemorrhage was 15.38％ (30/195).Univariate and multivariate logistic regression analysis showed that age,history of heart failure,door to needle time (DNT),systolic blood pressure (SBP) in 12 hours after thrombolysis and leukoaraiosis change were risk factors for hemorrhage in patients with mild cerebral infarction after thrombolysis (P ＜ 0.05).Conclusions Using low-dose alteplase for treating patients with mild cerebral infarction can achieve good thrombolytic effects.Age,history of heart failure,DNT,SBP in 12 hours after thrombolysis and leukoaraiosis change are influencing factors of intracranial hemorrhage,which should be paid attention to.
ABSTRACT
Objective To evaluate the cognitive level of proton pump inhibitors for the clinicians who prescribe these drugs often. Methods 10 cognitive latitudes for proton pump inhibitors were selected, which were receptor site, indication, indication of prophylaxis during perioperation, patients in contraindi-cated, high risk factors of stress ulcer, standard dose, daily dosing frequency, solvent selection for intrave-nous drip and main adverse reactions. Every cognitive latitude was assigned to points and one evaluation form was assigned 120 points. 175 clinicians participated the assessment voluntarily. Results Overall,the total average score is 58. 89. Each average score of 10 cognitive level is 10. 63, 1. 07, 6. 99, 5. 23, 3. 81, 11. 86, 11. 66, 3. 81, 7. 49 and 3. 81 respectively. The error rate is 10. 86％, 84. 57％, 45. 14％, 80. 00％, 59. 43％, 4. 00％, 2. 86％,80. 57％, 21. 71％ and 28. 00％ accordingly. Conclusions Over-all, the clinicians'cognitive level is low, while the senior doctors'are high in surgical prophylaxis;the physi-cians'are high in compatibility than surgeons ;the clinicians who used proton pump inhibitors ( PPI) more frequently are high in solvent selection for intravenous drip.
