ABSTRACT
Objective To evaluate the effect of carbapenem exposure on isolation rate of multidrug resistant organisms(MDROs) and prognosis of elderly patients with severe pneumonia.Methods Elderly patients with severe pneumonia and admitted to the intensive care unit in a hospital between February 2014 and February 2016 were investigated retrospectively.According to whether there was carbapenem exposure,patients were divided into group A(carbapenem exposure group) and group B(carbapenem non exposure group).Patients in group A were subdivided into two subgroups according to exposure time of carbapenems,group A1 received carbapenems for＞7 days,group A2 received carbapenems for ≤7 days.The isolation rates of MDROs,mechanical ventilation days,length of stay in ICU,and 28 day mortality among groups were compared and analyzed.Results A total of 86 patients were enrolled in the investigation,57 were males and 29 were females;the average age was (80.12 + 10.45) years (range:65-92 years).There were 40 cases in group A,46 in group B;24 cases in group A1,and 16 in group A2.The isolation rates of MDROs in group A and group B were 65.00％ and 36.96％ respectively,difference was sta tistically significant(P＜0.05);Comparison between two groups of patients revealed that mechanical ventilation days,length of stay in ICU,and 28 day mortality in group A were all higher than group B,difference was statistically significant(all P＜0.05);the isolation rates of MDROs in group A1 was higher than group A2 (75.00％ vs 43.75％,P＜0.05)；mechanical ventilation days of group A1 was higher than group A2 ([7.69 ± 2.22]d vs [6.34±-1.56]d,P＜0.05);28-day mortality and length of stay in ICU between group A1 and A2 were not significantly different(both P＞0.05).Conclusion Carbapenem exposure can increase the occurrence of MDRO infection,especially the non-fermentative bacterial colonization or infection,and prolong the mechanical ventilation days and length of stay in ICU,thus affect the prognosis of patients.
ABSTRACT
<p><b>OBJECTIVE</b>To determine the impact of adjunctive Buchang Naoxintong Capsule (, NXT) on dual antiplatelet therapy in patients with cytochrome P450 2C19*2 (CYP2C19*2) polymorphism undergoing percutaneous coronary intervention (PCI).</p><p><b>METHODS</b>Ninety patients with CYP2C19*2 polymorphism were enrolled, and their genotypes were confirmed by polymerase chain reaction (PCR). The patients were randomly assigned to receive either adjunctive NXT (triple group, 45 cases) or dual antiplatelet therapy (dual group, 45 cases) using a computer-generated randomization sequence and sealed envelopes. Platelet function was assessed at baseline and 7 days after treatment with conventional aggregometry. Subsequent major adverse cardiovascular events (MACE, including sudden cardiac arrest and acute coronary syndrome) were recorded during a 12-month follow-up.</p><p><b>RESULTS</b>Baseline platelet function measurements were similar in both groups. After 7 days, percent inhibitions of maximum platelet aggregation and late platelet aggregation were significantly greater in the triple versus dual group (42.3%±16.0% vs. 20.8%±15.2%, P<0.01, and 54.7%±18.3% vs. 21.5%±29.2%, P<0.01, respectively). During the 12-month follow-up, the rate of subsequent MACE (6/45) was significantly lower in the triple group compared with the dual group (14/45; P<0.05).</p><p><b>CONCLUSION</b>Adjunctive NXT to maintenance dose clopidogrel (75 g) could enhance the antiplatelet effect and decrease subsequent MACE in patients with the CYP2C19*2 polymorphism undergoing PCI.</p>

Mitochondrial diabetes [mtDM] which is caused by genetic defect of islet B cells is a new subtype of diabetes. It has many clinical manifestations compared with ordinary diabetes. We reviewed our nursing experiences on four cases with mtDM and focused on the nursing characteristics and management in order to explore specific care knowledge for mtDM
