Responsibilities and influencing factors of infection control liaison nurses in general hospitals / 中国感染控制杂志

Objective To clarify the responsibilities and influencing factors of infection control liaison nurses(ICLNs)in general hospitals.Methods Relevant databases were systematically retrieved with scoping review method from establishment to March 18,2023,and the included literatures were reported standardizedly.Results A total of 36 literatures were included in the analysis.Responsibilities of ICLNs included admittance criteria,selec-tion methods,and job responsibilities.Influencing factors of ICLNs included training,empowerment,performance evaluation,continuous improvement measures,and personnel allocation.After the establishment of ICLNs,inci-dence of healthcare-associated infection and detection rate of multidrug-resistant organisms were reduced,compli-ance rate of health care workers'hand hygiene and monitoring rate of hospital environment were improved,and the cleaning and disinfection of hospital environment was standardized.Conclusion ICLNs play a role in preventing and controlling the occurrence of healthcare-associated infection.The management and application should be further standardized and improved,the effectiveness of ICLNs needs to be thoroughly studied,so as to promote the deve-lopment of ICLNs,and improve the quality of healthcare-associated infection management.

Alteration of brain functional connectivity strength in patients with type 2 diabetes and its neuropathological mechanism / 解放军医学杂志

Objective To explore the change of brain functional connectivity strength in patients with type 2 diabetes mellitus(T2DM)and its neuropathological mechanism.Methods Fifty-six T2DM patients who visited Gansu Provincial Hospital from October 2017 to March 2021 were selected as T2DM group,and 48 healthy controls were selected as control group.A prospective study was conducted on the changes in brain function in T2DM patients by analysis of resting state functional connectivity strength(FCS)and functional connectivity(FC)based on seed points.Brain functional magnetic resonance imaging,clinical variable collection,and neuropsychological testing of patients in two groups were performed.We calculate the FCS value,evaluate the brain function changes of the two groups in the resting state,take the brain regions with significant differences between the groups as the seed points and perform functional connectivity analysis with the whole brain.Correlation analysis was conducted between the FCS,FC values of the different brain regions and clinical variables such as fasting blood glucose(FPG),glycosylated hemoglobin(HbA1c),thyroid hormone(TSH)levels,as well as the scores of mini mental state examination(MMSE),Montreal cognitive assessment(MoCA),clock drawing test(CDT),Hamilton Depression Rating Scale(HAMD-24)and Hamilton Anxiety Scale(HAMA).Results Compared with control group,the HAMD-24 and HAMA scores in T2DM group significantly increased(P<0.01),while the MoCA scores decreased(P<0.05);In T2DM group,the FCS value of the right middle temporal gyrus increased(GRF correction,voxel level P<0.001,clustering level P<0.05),and the FC value of the right middle temporal gyrus-left anterior cingulate cortex decreased(GRF correction,voxel level P<0.001,clustering level P<0.05).Correlation analysis showed that the FC value of right middle temporal gyrus-left anterior cingulate cortex in T2DM patients was negatively correlated with HAMD-24 score(r=-0.395,P=0.003),HbA1c level(r=-0.303,P=0.023),and positively correlated with TSH level(r=0.324,P=0.017).Conclusions The increase of FCS value in the right middle temporal gyrus and the decrease of FC value in the right middle temporal gyrus-left anterior cingulate cortex may be important neuroimaging features of brain function damage in T2DM patients.HbA1c may play an important role in the process of brain damage in T2DM patients.

Current status of exclusive breastfeeding for the second child and factors influencing exclusive breastfeeding in the context of the universal two-child policy / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To investigate the current status of exclusive breastfeeding for the second child in the context of the universal two-child policy and the factors influencing exclusive breastfeeding.</p><p><b>METHODS</b>A self-designed questionnaire for the current status of breastfeeding and related factors influencing breastfeeding for the second child were used to survey 836 mothers with a second child, who were selected by cluster sampling, in Quzhou, Zhejiang, China.</p><p><b>RESULTS</b>A total of 680 usable questionnaires were obtained. The rate of exclusive breastfeeding for the second child was significantly lower than for the first child (34.9% vs 42.2%; P<0.05). The univariate analysis revealed that there were significant differences between the exclusive and non-exclusive breastfeeding groups in the mother′s age, education background, occupation and time of maternity leave, mode of delivery of the first child, sex of the first child, feeding pattern of the first child, mode of delivery of the second child, whether the second child was admitted to the intensive care unit, whether the father supported breastfeeding, and whether the grandmother/maternal grandmother supported breastfeeding (P<0.05). The multivariate logistic regression analysis showed that artificial feeding+partial breastfeeding for the first child (OR=12.286, P<0.05), cesarean section for the second child (OR=1.724, P<0.05), and having no breastfeeding support from the maternal grandmother (OR=1.651, P<0.05) were main factors for influencing exclusive breastfeeding.</p><p><b>CONCLUSIONS</b>The current status of exclusive breastfeeding for the second child is not optimistic in the context of the universal two-child policy. Education about breastfeeding should be taken seriously at the birth of the first child, the rate of cesarean section should be reduced, and the family members should support exclusive breastfeeding, in order to improve the status of exclusive breastfeeding.</p>

The exploration of the academic thought of external treatment master-Wu ShiJi / 中国针灸

To explore Wu Shiji's academic thought, his external treatment method were arranged and summarized, such as treatment based on triple energizer differentiation, the theory of plaster heals various disease and the combination of the application of acupuncture, moxibustion and plaster etc. It has been proved that Wu's external treatment had compiled all the advantages of each school of Chinese medicine before his era, rich in content and convenient to use. So it values highly in clinical practice and has provided great convenience for the modern clinical research of external treatment.

Is it necessary to stent renal artery stenosis patients before cardiopulmonary bypass procedures? / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Acute kidney injury (AKI) is associated with poor prognosis after cardiopulmonary bypass. The aim of this retrospective study was to investigate whether stent implantation before cardiopulmonary bypass has beneficial effect on development of AKI in renal artery stenosis (RAS) patients.</p><p><b>METHODS</b>In this retrospective study, patients with abnormal baseline serum creatinine (SCr, > 106 µmol/L) were not included. Included patients (n = 69) were divided into two groups. Group 1 included 31 RAS patients receiving no stent implantation before cardiopulmonary bypass. Group 2 included 38 RAS patients having received stent implantation just before cardiopulmonary bypass. To assess AKI after cardiopulmonary bypass, serum urea nitrogen, SCr and creatinine clearance were recorded at baseline, at the end of operation, during the first and second postoperative 24 hours.</p><p><b>RESULTS</b>Baseline characteristics were similar between groups. Serum urea nitrogen, SCr, creatinine clearance before and after cardiopulmonary bypass were also similar class groups. Incidence of AKI in group 1 was not significantly different from group 2. In group 1, AKI defined by RIFLE between occurred in 7 (22.6%) patients: 5 (16.1%) with RIFLE-R, 2 (6.5%) with RIFLE-I, and no patients with RIFLE-F. In group 2, 10 patients (26.3%) had an episode of AKI during hospitalization: 6 (15.8%) had RIFLE-R, 4 (10.5%) had RIFLE-I, and no patients had RIFLE-F.</p><p><b>CONCLUSIONS</b>There are no data suggesting that it is necessary to stent RAS patients with normal SCr before cardio-pulmonary bypass. However, it cannot be concluded that RAS is not associated with AKI after cardiopulmonary bypass.</p>
