To investigate the genetic relatedness between carbapenem-resistant Klebsiella pneumoniae(CRKP) strains isolated from intestinal colonization and subsequent bloodstream infections.

(±)-Talapyrones A-F (1-6), six pairs of dimeric polyketide enantiomers featuring unusual 6/6/6 and 6/6/6/5 ring systems, were isolated from the fungus Talaromyces adpressus. Their structures were determined by spectroscopic analysis and HR-ESI-MS data, and their absolute configurations were elucidated using a modified Mosher's method and electronic circular dichroism (ECD) calculations. (±)-Talapyrones A-F (1-6) possess a 6/6/6 tricyclic skeleton, presumably formed through a Michael addition reaction between one molecule of α-pyrone derivative and one molecule of C₈ poly-β-keto chain. In addition, compounds 2/3 and 4/5 are two pairs of C-18 epimers, respectively. Putative biosynthetic pathways of 1-6 were discussed.

Objective:To analyze the influence of E-Coaching self-management model on health behavior change in perimenopausal women.Methods:In this randomized controlled trial, 230 perimenopausal women who participated in health management prograam in the Health Management Center of Hangzhou Wuyunshan Hospital from January 2020 to October 2021 were selected as study objects by convenience sampling method. The subjects were divided into the experimental group and the control group with random number table (115 cases in each group). The experimental group was managed by health coaches with E-Coaching self-management model, and the control group was routinely managed by health managers. The intervention lasted for 6 months. Finally, 29 cases were lost to follow-up due to the failure of the subjects to comply with protocol requirements or voluntary withdrawal. So, a total of 201 subjects were included in the analysis (107 cases in the experimental group and 94 cases in the control group). χ2 test and t test were used to analyze the differences in modified Kupperman symptom score, perimenopausal knowledge and belief, regular exercise and dietary healthy behavior stage between the two groups. And the influence of E-Coaching self-management model on health behavior change in perimenopausal women was analyzed too. Results:After the intervention, the total score of modified Kupperman scale and the scores of insomnia, anxiety and fatigue in the experimental group were all lower than those in the control group [(7.36±2.91) vs (10.01±2.78) points, (0.49±1.13) vs (1.27±1.20) points, (0.80±0.99) vs (1.68±1.39) points, (0.67±0.55) vs (0.93±0.64) points]( t=6.553, 4.785, 5.219, 3.013, all P<0.05); and the total score of knowledge and belief questionnaire and the score of knowledge or belief dimension in the experimental group were significantly higher than those in control group [(25.15±1.55) vs (21.05±1.64) points, (9.61±0.56) vs (9.03±0.68) points, (15.54±1.53) vs (12.02±1.28) points] ( t=-18.238, -6.570, -17.801, all P<0.05). After the intervention, the proportions of the experimental group in the precontemplation and contemplation stage of exercise and diet were both significantly lower than those before intervention ( χ2=116.616, 139.964, both P<0.001), and were lower than those in the control group (the proportion of precontemplation stage of exercise was 7.5% vs 38.3%, and the contemplation stage of exercise was 26.2% vs 34.0%, χ2=38.330; the proportion of precontemplation stage of diet was 3.7% vs 23.4%, and the contemplation stage of diet was 18.7% vs 29.8%, χ2=25.399; all P<0.001). After the intervention, the proportion of the subjects in the preparation stage and action stage the experimental group were significantly higher than those before intervention ( χ2=116.616, 139.964, both P<0.001), and were higher than those in the control group (the proportion in preparation stage of exercise 18.7% vs 8.5%, and the action stage of exercise 47.7% vs 19.1%, χ2=38.330; the proportion in preparation stage of diet 20.6% vs 14.9%, and the action stage of diet 57.0% vs 31.9%, χ2=25.399; all P<0.001). Conclusion:E-Coaching self-management model can improve women′s perimenopausal symptoms in certain degrees, it improves their understanding of perimenopausal knowledge, enhances self-management beliefs and promotes healthy behavior changes.

Spontaneous aortic thrombosis is exceedingly rare, and optimal treatment remains uncertain. We present an unusual case of a spontaneous aortic thrombus at the renal artery level in a patient undergoing active cisplatin treatment for urothelial carcinoma. Management included catheter-directed thrombolysis followed by thrombectomy. An open cutdown was performed on the left common femoral artery (CFA), with right groin access via a 6-Fr sheath. Clamping of the left superficial and deep femoral arteries, along with balloon occlusion of the right common iliac artery, prevented distal embolization. A Coda balloon introduced via direct left CFA puncture with a 20-Fr sheath was positioned above the aortic thrombus. After inflation, clots were trawled to the sheath, “sandwiching” the clots before removal of the balloon and sheath via the left groin. Post-operatively, the patient recovered well and received continued therapeutic anticoagulation.
