Self-care in individuals with chronic kidney disease on hemodialysis / Autocuidado em pessoas com doença renal crônica em hemodiálise / Autocuidado en personas con enfermedad renal crónica en hemodiálisis

ABSTRACT Objective: To understand how self-care is carried out by people with chronic kidney disease on hemodialysis. Method: A qualitative approach was used. Data was collected through semi-structured interviews in 12 individuals on hemodialysis in Chile between September and December 2018. Dorothea Orem's self-care theory was used for directed content analysis. Results: Three categories emerged: self-care requirements, self-care deficit, and education and information management for self-care. People were aware of the importance of carrying out their self-care. They also stated not to carry out the care actions rigorously enough showing some limitations. Finally, people's knowledge about their condition was usually acquired from the Internet and from their own experience rather than through consultations with a health team. Considerations: People are conscious about their role in their health in a flexible way. The health team should know how to recognize conditions interfering in people's self-care and help to overcome them.

RESUMO Objetivo: Compreender como o autocuidado é realizado por pessoas com doença renal crônica em hemodiálise. Método: Abordagem qualitativa com entrevistas semiestruturadas com 12 pessoas que realizavam hemodiálise no Chile entre os meses de setembro e dezembro de 2018. A análise de conteúdo foi conduzida pela teoria do autocuidado de Dorothea Orem. Resultados: Surgiram três categorias: requisitos de autocuidado, déficit de autocuidado e educação e manejo de informação para o autocuidado. As pessoas reconheceram a importância de realizar seu autocuidado. No entanto, referiram não realizar o cuidado com o rigor que deveriam. Os conhecimentos que possuíam foram adquiridos na internet ou de sua própria experiência, sem recorrer à equipe de saúde. Conclusões: As pessoas são conscientes de seu papel na manutenção de sua saúde, mas de maneira flexível. A equipe de saúde deve saber reconhecer os aspectos que interferem no autocuidado e ajudar as pessoas a superá-los.

Conclusiones: Las personas demostraron ser conscientes de su rol en preservar su salud, pero de forma flexible. El equipo de salud debe reconocer los aspectos que interfieren en el autocuidado y ayudar a las personas a superarlos.

Association between cumulative exposure to blood pressure and new-onset chronic kidney disease / 中华肾脏病杂志

Objective To investigate the association between cumulative exposure blood to pressure (cum BP) and new-onset chronic kidney disease (CKD).Methods In this prospective cohort study,101 510 employees of Kailuan Group receiving annual health examination during 2006 to 2007 were observed.The participants received the second,third,and fourth annual health examinations during 2008 to 2009,2010 to 2011,and 2012 to 2013 year respectively.Their urinary and serum creatinine were tested,and participants with incomplete SBP,DBP data and CKD were excluded.Further excluding those who somehow failed to take annual health examination,with incomplete data,or new-onset CKD 27 809 participants were selected in the analysis.According to cum BP exposure quintile grouping:Q1 ＜ 3.70 scores;Q2:3.70-6.16 scores;Q3:6.17-8.45 scores;Q4:8.46-10.95scores;Q5 ≥ 10.96 scores.Multivariate Logistic regression was used to analyze the association between cum BP level and new-onset CKD by cum BP exposure quintile grouping.Results The rise of cum BP exposure level caused the increased incidence of CKD.The incidences of CKD in the five quintile groups were 2.59％,3.11％,4.19％,5.81％,and 7.73％ respectively (P＜ 0.01).Compared with Q1 group,multivariate logistic regression analysis showed that after the adjustment of age,gender,education,income,smoking,drinking,BMI,FBG,TC,TG,LDL,HDL,UA and CRP,the incidences of CKD gradually increased in the Q2,Q3,Q4,and Q5 cum BP quintile groups,and OR(95％CI) values were 1.08(0.86-1.35),1.26(1.01-1.58),1.57(1.27-1.95),1.78(1.43-2.21) respectively (P for trend ＜0.01).Similar results were obtained in different genders.For each single point increase of cum BP exposure level,the incidence of CKD increased 6％ in the general population (P for trend ＜ 0.01),increased 8％ in male (P for trend ＜ 0.01),and 3％ in female (P for trend=0.12).Conclusion As the cumulative exposure to blood pressure increases,the risk of CKD incidence rises,especially in men.

Correlative analysis between contrast-enhanced ultrasonography and 99mTc-DTPA renography in evaluation of renal insufficiency / 中华肾脏病杂志

Objective To evaluate the contrast-enhanced ultrasonography (CEUS) in quantitative diagnosis of chronic renal insufficiency. Methods Correlation of CEUS indexes with glomerular filtration rate (GFR) detected by 99mTc-DTPA renography was examined. Thirty-three cases of clinical chronic renal insufficiency were enrolled in the study. They were 15 males and 18 females with average age of (43.33±6.78) years. After intravenous bolus injection of 1 ml SonoVue,CEUS of renal cortex blood perfusion was performed successfully, and a time-intensity curve (TIC)was created with PHILIPS iU22 system's QLAB software. A 148 to 222 MBq dose of 99mTc-DTPA was injected as a bolus from antecubital vein. Renal scintigraphic images were collected immediately and GFR was obtained. Results The significant correlation coefficients between GFR and CEUS quantitative indexes were as follows: rAUC (area under curve)=0.886 (P＜0.05), rA (slope rate of ascending curve, A) =0.804(P＜0.05). However, rDPI (derived peak intensity, DPI)=0.021 (P＞0.05), rTTP (time to peak, TTP) =0.043 (P＞0.05), rα (slope rate of descending curve,α)=0.039 (P＞0.05). Conclusion CEUS can precisely display the hemodynamic change of chronic renal insufficiency, which is well correlated with GFR by 99mTc-DTPA renography.

Arterial stiffness and associated factors in non-diabetic pre-dialysis patients with chronic kidney disease / 中华肾脏病杂志

Objective To study the arterial stiffness in non-diabetic pre-dialysis chronic kidney disease (CKD) patients and to explore the associated factors. Methods Automatic pulse wave velocity (PWV) measuring system was used to examine carotid-femoral pulse wave velocity (CFPWV) as the parameters reflecting central elastic large arterial elasticity. Vascular calcification was quantitatively evaluated by plain radiographic film of abdomen, pelvis and hands. Blood pressure, biochemical parameters and intact parathyroid hormone (iPTH) were routinely detected. Stepwise multiple linear regression analysis was used to assess the associated factors of arterial stiffness. Results Ninety-six non-diabetic pre-dialysis CKD patients and 30 healthy people were enrolled in this trial. CFPWV in stage 3, 4 and 5 CKD patients was significantly higher than that in healthy controls [(11.63±2.39) m/s, (11.70±2.80) m/s, (12.88±2.49) m/s vs (9.70±1.66)m/s , all P<0.05]. Stepwise multiple regression analysis demonstrated that age, mean arterial pressure, vascular calcification and iPTH were independent impact factors of CFPWV. Conclusions Arterial stiffness of large artery increases in non-diabetic pre-dialysis CKD patients. Age, mean arterial pressure, vascular calcification and iPTH are independent impact factors of CFPWV.

Stroke and its related factors in chronic kidney disease patients / 中华肾脏病杂志

Objective To investigate the stroke occurrence of chronic kidney disease (CKD) and its related factors, especially the carotid atherosclerosis. Methods The data of stroke occurrence in 700 CKD patients hospitalized in Renji Hospital during 2007 were analyzed retrospectively. The incidences of stroke were compared among CKD [Ⅰ-Ⅱ, CKD Ⅲ-Ⅴ non-dialysis patients and dialysis patients. Carotid atherosclerosis of 409 CKD patients was examined by color Doppler ultrasound. The related factors were selected by Spearmnan correlation analysis and Logistic regression analysis. Results Of 700 CKD patients, 67 cases (9.57%) experienced at least one episode of stroke, which was much higher than that of general population. The related factors of stroke in CKD included GFR, age, SBP, CRP, Lpa, serum glucose, pre-albumin, HDL and carotid atherosclerosis. Logistic regression revealed that SBP (β=1.021, P=0.042), CRP (β=1.008, P=0.024) and carotid atherosclerosis (β =3.456, P=0.025) were risk factors of stroke in CKD. Incidence of carotid atherosclerosis was high (50.37%) in CKD patients, besides it was significantly higher in CKD patients with stroke history as compared to those without stroke history (80.0% vs 47.4%, P<0.01). Conclusions The incidence of stroke is quite high in CKD patients, which is closely associated with hypertension, inflammation and glyeolipid metabolism disorder. Carotid atherosclerosis is common in CKD patients with stroke, which may be helpful in screening cerebrovascular diseases in CKD patients.
