Evaluation of the effectiveness of preventive nursing measures for pressure injuries in patients in the neurology intensive care unit

BACKGROUND Patients in neurology intensive care units(ICU)are prone to pressure injuries(PU)due to factors such as severe illness,long-term bed rest,and physiological dysfunction.PU not only causes pain and complications to patients,but also increases medical burden,prolongs hospitalization time,and affects the recovery process.AIM To evaluate and optimize the effectiveness of pressure injury prevention nursing measures in neurology ICU patients.METHODS A retrospective study was conducted,and 60 patients who were admitted to the ICU of the Department of Neurology were selected and divided into an observation group and a control group according to the order of admission,with 30 people in each group.The observation group implemented pressure injury prevention and nursing measures,while the control group adopted routine care.RESULTS Comparison between observation and control groups following pressure injury prevention nursing intervention revealed significantly lower incidence rates in the observation group compared to the control group at 48 h(8.3%vs 26.7%),7 d(16.7%vs 43.3%),and 14 d(20.0%vs 50.0%).This suggests a substantial reduction in pressure injury incidence in the observation group,with the gap widening over time.Additionally,patients in the observation group exhibited quicker recovery,with a shorter average time to get out of bed(48 h vs 72 h)and a shorter average length of stay(12 d vs 15 d)compared to the control group.Furthermore,post-intervention,patients in the observation group reported significantly improved quality of life scores,including higher scores in body satisfaction,feeling and function,and comfort(both psychological and physiological),indicating enhanced overall well-being and comfort following the implementation of pressure injury prevention nursing measures.CONCLUSION Implementing pressure injury preventive care measures for neurology ICU patients will have better results.

Obstructive shock secondary to fungal prosthetic aortic valve endocarditis

Dear editor,Fungal endocarditis is a rare disease with a poor prognosis,suboptimal diagnostic tools responsible for long diagnostic delays in most cases,and poorly defined activity of most antifungal agents in endocarditis.^([1])The burden of diagnosis still lies with clinicians:they need a

LncRNA NKILA suppresses airway hyper reactivity via interfering the facilitation of MUC5AC and MUC5B mediated by GALNT2

Glycosylation of mucins mediated by N-acetylgalactosaminyltransferases(GALNTs)is closely related to respiratory diseases such as asthma and chronic obstructive pulmonary disease(COPD).In addition,long non-coding RNAs(LncRNAs)participate in physiological and pathological processes through various epigenetic mechanisms.In this study,we found that a novel LncRNA named NKILA combined with multiple mucins and GALNTs potentially by several bioinformatics methods,and we used quantitative real-time PCR(RT-qPCR)to detect the expressions of NKILA,MUC5AC,MUC5B,and GALNT2 mRNA in 50 cases of asthma samples and 19 cases of normal samples,whose results showed that the expression of NKILA was significantly decreased in asthmatic samples,negatively correlated with the severity of asthma and the expressions of MUC5AC and MUC5B,while GALNT2 was significantly increased in asthmatic tissues,and positively correlated with the severity of asthma and the expressions of MUC5AC and MUC5B.In vitro,we used transient transfection technology to overexpress or interfere with NKILA and GALNT2 and then detected the expressions of MUC5AC and MUC5B via RT-qPCR and Western blot,which demonstrated GALNT2 can promote the expressions of MUC5AC and MUC5B protein,while NKILA could inhibit this effect.Furthermore,co-immunoprecipitation results showed that GALNT2 could bind to MUC5AC and MUC5B protein.RNA immunoprecipitation and RNA pull-down experiments showed that NKILA could bind to GALNT2.These evidences suggested that there are correlations among the expression of NKILA,GALNT2,MUC5AC,and MUC5B proteins in asthmatic patients.Mechanically,we concluded that NKILA can suppress the O-linked glycosylation of MUC5AC and MUC5B proteins by binding to GALNT2 and inhibit the expression of MUC5AC and MUC5B proteins.Our researches provided a potential therapeutic target for AHR.

Effect of ganglioside sodium on stress, neural injury degree, rebuilding related factors of neural function and coagulation index in patients with severe craniocerebral injury

Objective:To investigate the effect of ganglioside sodium on stress, neural injury degree, rebuilding related factors of neural function and coagulation index in patients with severe craniocerebral injury.Methods: From June 2016 to March 2018, 90 cases of severe craniocerebral injury in our hospital were randomly divided into 45 cases of ganglioside sodium group (group GM1) and 45 cases of control group. The levels of stress [including norepinephrine (NE) and cortisol (Cor)], nerve injury [including neuron-specific enolase (NSE), astrocyte-derived protein (S100beta), ubiquitin carboxyl terminal hydrolase L1 (UCH-L1), glial fibrillary acidic protein (GFAP)], nerve function reconstruction [including brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF)] and coagulation function [including prothrombin time (PT), thrombin time (TT), activated partial prothrombin time (APTT) and fibrinogen (FIB)] were observed and compared between the two groups. Results:Before treatment, there was no significant difference in stress hormone, nerve injury degree, nerve function reconstruction and coagulation function between the two groups.After treatment, the levels of cytokines and FIB in the two groups were significantly higher than those before treatment, and the levels of stress hormone, nerve injury molecule and TT were significantly lower than those before treatment.The levels of cytokines and FIB in GM1 group were significantly higher than those in the control group. The levels of stress hormone, nerve injury molecule and TT in GM1 group were significantly lower than those in the control group. There was no significant difference in the levels of PT and APTT between the two groups before and after treatment.Conclusions: The treatment of severe craniocerebral injury with ganglioside sodium on the basis of routine treatment can relieve body stress and nerve damage, also, facilitate nerve function reconstruction and improve coagulation function.

Anti-N-Methyl-D-Aspartate Receptor Encephalitis with Concomitant Detection of <i>Epstein-Barr</i>Virus

Introduction: Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an important cause of encephalitis worldwide. While some cases are associated with neoplasms, in the remaining cases the etiology is unclear. Recent literature suggests that viral brain infections, mainly of the herpesviridae family, may be associated and/or trigger NMDAR encephalitis. Case Report: A 34-year-old woman with a 1-month-long history of progressive behavioral and language deterioration came to emergency department after a first unprovoked seizure followed by a focal status epilepticus. Brain computerized tomography was normal, but electroencephalography showed epileptiform activity over the left fronto-temporal region. She was admitted to the intensive care unit. Brain magnetic resonance imaging showed subtle T2 hypersignal in the parietal, fronto-opercular and insular regions. Cerebrospinal fluid (CSF) was positive for Epstein Barr virus (EBV) DNA whilst anti-NMDA antibodies were identified both in the CSF and blood. No tumors were detected after thorough investigation. Following intravenous steroids, plasma exchange and rituximab treatment she slowly improved being discharged home and at a 3-month follow-up she was sequels free. Conclusion: Despite the clear association between herpes virus simplex and NMDAR encephalitis, no such unequivocal relation has been reported for other virus, namely EBV. We report a case of NMDAR encephalitis which might be associated and triggered by EBV infection, identified by polymerase chain reaction.
