A questionnaire to assess the health information literacy of patients with intermediate-stage chronic kidney disease.

AIM: To investigate the status and influencing factors of health information literacy in patients with intermediate-stage chronic kidney disease (CKD). DESIGN: A prospective clinical study. METHODS: We used a CKD health information literacy questionnaire to survey 130 patients with intermediate-stage CKD and valuate their health needs and health knowledge. We performed the study in strict accordance with the Guidelines for Clinical Trial Protocols. We registered the study in the Chinese Clinical Trial Registration Center (registration No. ChiCTR2100053103; approval No. K56-1). RESULTS: The overall health information literacy of CKD was relatively low. Low education level, advanced age and unemployment were influencing factors. The scores of assessment ability, literacy awareness, application ability, integration ability and CKD health knowledge reserve were relatively low. The generalized linear model showed that the older the men, the lower their health information literacy.

Effects of continuous renal replacement therapy on renal inflammatory cytokines during extracorporeal membrane oxygenation in a porcine model.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) has been recommended for the treatment of patients with acute, potentially reversible, life-threatening respiratory failure which unresponsive to conventional therapy. But it is unclear about how ECMO affects renal tissue. METHODS: Twenty-four piglets weighing 25 to 32 kg were used in this experiment. The piglets were randomly allocated to 4 groups of 6 animals each: sham group (S group), control group (C group), VV-ECMO group (E group), VV-ECMO combined with CRRT group (EC group). The piglets were sacrificed and the kidney tissue were harvest to determine the levels of IL-1ß, IL-6, TNF-α and NF-КB by using the ELISA and RT-PCR method, respectively. RESULTS: Compared with C group and S group, E group renal tissue IL-1ß, IL-6, TNF-α and NF-КB expression increased significantly, respectively (p < 0.01). Compared with E group, EC group showed renal tissue IL-1ß, IL-6, TNF-α and NF-КB expression decreased significantly, respectively (p < 0.05). CONCLUSION: ECMO enables to inflammatory cytokines including IL-1ß, IL-6, TNFα, NF-КB released significantly, renal function impaired and immune homeostasis were to imbalance; ECMO combined with CRRT treatment can alleviate levels of inflammatory cytokines, maintain immune homeostasis balance and thus ameliorate the ECMO-related acute kidney injury(AKI).

The effect of vasopressin on the hemodynamics in CABG patients.

BACKGROUND: Vasopressin is widely used to treat various type of hypotension, but the effect of vasopressin on coronary artery bypass grafting surgery (CABG) patients is not clear. This study was to investigate the effect of vasopressin on the hemodynamics in CABG patients. METHODS: Twenty coronary artery disease (CAD) patients were randomly divided into two groups: norepinephrine group and vasopressin group. During the anesthesia and the operation, the central venous pressure (CVP) and pulmonary capillary wedge pressure (PCWP) were maintained to 8-10cmH2O, and the hemocrit was maintained above 30% through lactate ringer's mixture, artifact colloid and red blood cells. The invasive artery blood pressure (IBP) was maintained by appropriate anesthetic depth and norepinephrine or vasopressin respectively. The target IBP was 70 mmHg, and heart rate (HR) was 60 bpm. The MAP (mean artery pressure), HR, ST-T, CVP, PAP (pulmonary artery pressure), PCWP, SVR (systemic vascular resistance), PVR (pulmonary vascular resistance), CO (cardiac output), urine output, blood gas analysis, surgery duration and blood loss were monitored. RESULTS: The MAP, HR, and ST-T were stable in either group during the operation. CVP, PCWP and SVR increased but CI deceased during the posterior descending artery (PDA) was grafted in both groups and without any significant difference between them. PAP increased during PDA was grafted in either group and there was significant difference between the two groups. PVR increased during ADA and PDA being grafted in norepinephrine group but not in vasopressin group. Metoprolol usage was 11.2 mg and 5.9 mg in norepinephrine group and vasopressin group respectively. CONCLUSION: Vasopressin was better than norepinephrine.to keep the hemodynamics stability of patients undergoing CABG surgery.
