Chronic kidney disease (CKD) is a serious public health problem and its prevalence is growing in many countries, often related to issues resulting from the lifestyle in growing economies and the ...population's life expectancy. Nutritional therapy is a beneficial but still neglected strategy for preventing CKD and delaying disease progression. The aim of this study was to assess the association of dietary patterns with CKD development and progression. Observational studies conducted in adult humans and the correlation between the adopted dietary pattern and prevalent and incident cases of CKD were assessed. A significant association was observed between unhealthy dietary patterns and an increased risk of developing or worsening CKD, as well as an adverse effect. Whereas healthy eating patterns characterized by the consumption of fruit, vegetables and dietary fibre showed nephroprotective outcomes.
SUMMARY AT A GLANCE
Chronic kidney disease (CKD) and dietary patterns have been investigated in different studies. There is evidence that healthy dietary patterns can prevent CKD or at least delay its onset and slow its progression. A diet with a lower intake of salt, sweets, fats and proteins is associated with a lower risk of kidney injury.
In several countries, patients with end-stage renal disease who are ineligible for dialysis are considered urgency priority (UP) for kidney transplantation (KT) through distinct allocation rules. ...There are scarce published data on clinical features and outcomes after KT of these patients.
We retrospectively reviewed and compared demographic and clinical pretransplant characteristics and outcomes after KT of all patients transplanted under UP allocation in a single Brazilian transplant center from January 10 to March 16 (n = 74) and 1: 1 patients transplanted under standard allocation in the same period (n = 74). A propensity score (PS) matching analysis was performed to evaluate risk factors for death-censored graft loss.
UP KT group presented higher percentage of women (58.1 vs. 33.8%, p = 0.005), higher class I (22.2 ± 32.9 vs. 13.1 ± 25.3%, p = 0.027) and class II panel reactive antibodies (11.5 ± 24 vs. 5.2 ± 19.1%, p = 0.002), higher HLA mismatches (4.9 ± 0.9 vs. 3.7 ± 1.2, p < 0.001), higher percentage of retransplants (27 vs. 4.1%, p < 0.001), and spent longer time on dialysis off the waiting list (WL; 54.5 ± 52.5 vs. 31.2 ± 29.0 months, p = 0.03). After transplantation, UP KT patients presented longer hospital stay (29.3 ± 35.7 vs. 18.5 ± 19.5 days, p = 0.003) and inferior death-censored graft survival at 3 years (82 vs. 95.8%, log rank = 0.016), with 33.3% of graft losses due to vascular thrombosis. In PS-matched multivariable analysis, UP status hazard ratios (HR 4.791, 95% CI 1.052-21.722, p = 0.042) and donor age (HR 1.071, 95% CI 1.003-1.145, p = 0.041) were independent risk factors for death-censored graft loss.
Patients transplanted under UP status remained a longer time on dialysis off the WL, suggesting that long-term dialysis led to exhaustion of accesses. After transplantation, outcomes are inferior and UP status was a risk factor for graft loss. These results point to the need for local policies to encourage and monitor the early referral to KT.
to evaluate the use of a renal health application by kidney transplant recipients.
a retrospective, observational study with a sample composed of individuals registered in the kidney transplant ...section of the application from July of 2018 to April of 2021. Demographic data, data entry, time of use, weight, blood pressure, blood glucose, creatinine, medication schedules, appointments, and tests were the variables collected. Descriptive analysis of the data was performed.
eight hundred and twenty-three downloads of the application were identified, and 12.3% of those were registered as kidney transplant recipients, the majority from southeastern Brazil (44.9%), 36±11 years old, and female (59.1%). Of the sample, 35.1% entered information such as creatinine (62%), weight (58.2%), and blood pressure (51.8%). Most used the application for one day (63.3%) and 13.9% for more than one hundred days. Those who used it for more than one day (36.7%) recorded weight (69%), medication intake (65.5%) and creatinine (62%), and scheduled appointments (69%).
the kidney transplant recipient section of the Renal Health application generated interest in the young population, but showed low adherence throughout the assessed months. These results offer a relevant perspective on the implementation of mHealth technologies in kidney transplantation.
ABSTRACT Introduction: Chronic kidney disease (CKD) has been increasing significantly. There is evidence that a large part of the population does not have enough knowledge on the subject. Objective: ...To investigate the level of knowledge about CKD in the general population, its risk factors and means of prevention. Methods: We ran a cross-sectional study in the population of Fortaleza, Ceará – Brazil, between 2017 and 2020, with the application of a questionnaire on CKD, risk factors and prevention. Results: we interviewed 735 volunteers, with a mean age of 38 years, of which 55% were female. Only 17.2% correctly responded to the concept of CKD, and 5.8% knew the concept of creatinine. Low water intake was the most cited risk factor by respondents (79.3%). The main risk factors and direct causes of CKD (diabetes and hypertension) were mentioned less frequently (13.2% and 15.1%, respectively). Men were more correct regarding risk factors and ways to prevent CKD. Older respondents answered more correctly the questions about the definition of CKD (n = 22; 28.6%) and creatinine (n = 7; 9.0%). With regards to education there was a statistically significant correlation in all the questions (p < 0.05). Conclusion: There is little knowledge about CKD in the general population. Higher level of education is associated with better knowledge. More health education actions are needed so that the population becomes better acquainted with CKD and, consequently, can adopt more adequate prevention and control measures.
Resumo Introdução: A doença renal crônica (DRC) vem aumentando de forma significativa. Há evidências de que grande parte da população não tem conhecimento suficiente sobre o assunto. Objetivo: Investigar na população geral o nível de conhecimento sobre a DRC, seus fatores de risco e meios de prevenção. Métodos: Foi realizado estudo transversal na população de Fortaleza, Ceará, Brasil, entre 2017 e 2020, com aplicação de um questionário sobre DRC, fatores de risco e prevenção. Resultados: Foram entrevistados 735 voluntários, com média de idade de 38 anos, dos quais 55% eram do sexo feminino. Apenas 17,2% responderam corretamente ao conceito de DRC, e 5,8% sabiam o conceito de creatinina. A baixa ingestão hídrica foi o fator de risco mais citado pelos entrevistados (79,3%). Os principais fatores de risco e as causas diretas de DRC (diabetes e hipertensão) foram mencionados com menor frequência (13,2% e 15,1%, respectivamente). Os homens tiveram maior acerto com relação aos fatores de risco e às formas de prevenção da DRC. Os entrevistados com idade mais avançada responderam mais corretamente às perguntas sobre a definição de DRC (n = 22; 28,6%) e creatinina (n = 7; 9,0%). No que diz respeito à escolaridade, em todas as perguntas houve correlação estatisticamente significativa (p < 0,05). Conclusão: Há um baixo nível de conhecimento sobre a DRC na população geral. Maior nível de escolaridade associa-se a um melhor conhecimento. São necessárias mais ações de educação em saúde para que a população conheça melhor a DRC e consequentemente possa adotar medidas de prevenção e controle mais adequadas.

Abstract
Background and Aims
A global increase in the prevalence of chronic kidney disease (CKD) and, consequently, in the number of individuals submitted to renal replacement therapy (RRT) has been ...observed. In Brazil, there was an increase from 46,557 to 144,779 (>310%) in the number of people on dialysis between the years 2001 and 2020, respectively. Although peritoneal dialysis (PD) is a safe, low-cost and less aggressive dialysis method when compared to hemodialysis (HD) and can be performed at the home, HD remains the most common RRT type in Brazil (92.2%). This study aimed to validate a PD section incorporated into an existing m-Health application (app) called 'Renal Health®'.
Method
This is a methodological study, with a quantitative and applied approach. For internal validation of the app usability, ten specialists/researchers in the study topic from the Nursing Nephrology participated in the study, hereafter referred to as ‘judges’, who carried out the validation process of the content to be inserted into the Renal Health® app. The validation instrument was sent to them electronically, organized according to a Likert scale following a four-degree gradation. Based on the specialists’ answers, the means of agreement were calculated, which ranged from –1 for a negative evaluation; 0 (zero) for a neither positive nor negative evaluation; and, +1 when the evaluation was positive. Data evaluation was done using descriptive statistics and the calculation of the content validity index (CVI). Each item of the validation instrument was analyzed in relation to these obtained averages, which, if they were less than 80%, would indicate the need for modifications. An evaluation instrument was created with 22 items arranged in three domains: objectives (4), structure and presentation (15), and relevance (3), aiming to reflect the app functionality, usability and appearance.
Results
Regarding the objectives related to the PD section, none of items received an “irrelevant” assessment and its CVI ranged from 0.90 to 1.0, with an overall CVI of 0.95. The sub-items with the highest scores were related to the text being compatible with the target audience and the PD section of the app having adequate information/content to guide the patients. Among the 15 sub-items related to the structure and presentation of the PD section, six showed 90% agreement among the judges and were distributed as follows: they indicated that the information directed to the object of interest was sufficient and adequate; stated that the colors applied to the text were relevant and facilitated its use; that the subtitles applied were adequate and helped the user to understand the image; confirmed that the amount of illustration was adequate for the content of the material; that the illustrations were clear and easy to understand and that they were relevant to the content of the material and elucidated the content. The other sub-items had a maximum CVI (1.0) and the overall CVI for this domain was 0.95. Finally, regarding the relevance of the PD section, all sub-items showed 100% agreement among the participants, so that the overall CVI was 1.0. Regarding the qualitative analysis of the instrument, there was no disagreement between the judges and/or suggestions for changes in the PD section.
Conclusion
The present study allowed the validation of the PD section in the Renal Health® app, which showed good reliability and could promote the use of m-Health technology to support users undergoing this type of dialysis.
To identify factors associated with maternal death in patients admitted to an intensive care unit.
A cross-sectional study was conducted in a maternal intensive care unit. All medical records of ...patients admitted from January 2012 to December 2014 were reviewed. Pregnant and puerperal women were included; those with diagnoses of hydatidiform mole, ectopic pregnancy, or anembryonic pregnancy were excluded, as were patients admitted for non-obstetrical reasons. Death and hospital discharge were the outcomes subjected to comparative analysis.
A total of 373 patients aged 13 to 45 years were included. The causes for admission to the intensive care unit were hypertensive disorders of pregnancy, followed by heart disease, respiratory failure, and sepsis; complications included acute kidney injury (24.1%), hypotension (15.5%), bleeding (10.2%), and sepsis (6.7%). A total of 28 patients died (7.5%). Causes of death were hemorrhagic shock, multiple organ failure, respiratory failure, and sepsis. The independent risk factors associated with death were acute kidney injury (odds ratio OR = 6.77), hypotension (OR = 15.08), and respiratory failure (OR = 3.65).
The frequency of deaths was low. Acute kidney injury, hypotension, and respiratory insufficiency were independent risk factors for maternal death.
