Association between Fiber Intake and Risk of Incident Chronic Kidney Disease: The UK Biobank Study.

OBJECTIVES: Dietary fiber intake is associated with a lower risk of diabetes, cardiovascular disease, and cancer. However, it is unknown whether dietary fiber has a beneficial effect on preventing the development of chronic kidney disease (CKD). DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS: Using the UK Biobank prospective cohort, 110,412 participants who completed at least one dietary questionnaire and had an estimated glomerular filtration rate ≥60 mL/min/1.73 m2, urinary albumin-to-creatinine ratio <30 mg/g, and no history of CKD were included. The primary exposure was total dietary fiber density, calculated by dividing the absolute amount of daily total fiber intake by total energy intake (g/1,000 kcal). We separately examined soluble and insoluble fiber densities as additional predictors. The primary outcome was incident CKD based on diagnosis codes. RESULTS: A total of 3,507 (3.2%) participants developed incident CKD during a median follow-up of 9.9 years. In a multivariable cause-specific model, the adjusted hazard ratios (aHRs; 95% confidence intervals [CIs]) for incident CKD were 0.85 (0.77-0.94), 0.78 (0.70-0.86), and 0.76 (0.68-0.86), respectively, for the second, third, and highest quartiles of dietary fiber density (reference: lowest quartile). In a continuous model, the aHR for each +∆1.0g/1,000 kcal increase in dietary fiber density was 0.97 (95% CI, 0.95-0.99). This pattern of associations was similar for both soluble and insoluble fiber densities and did not differ across subgroups of sex, age, body mass index, hypertension, diabetes, smoking, and inflammation. CONCLUSION: Increased fiber intake was associated with a lower risk of CKD in this large well-characterized cohort.

Kidney health for all: bridging the gap in kidney health education and literacy.

The high burden of kidney disease, global disparities in kidney care, and the poor outcomes of kidney failure place a growing burden on affected individuals and their families, caregivers, and the community at large. Health literacy is the degree to which individuals and organizations have, or equitably enable individuals to have, the ability to find, understand, and use information and services to make informed health-related decisions and actions for themselves and others. Rather than viewing health literacy as a patient deficit, improving health literacy lies primarily with health care providers communicating and educating effectively in codesigned partnership with those with kidney disease. For kidney policy makers, health literacy is a prerequisite for organizations to transition to a culture that places the person at the center of health care. The growing capability of and access to technology provides new opportunities to enhance education and awareness of kidney disease for all stakeholders. Advances in telecommunication, including social media platforms, can be leveraged to enhance persons' and providers' education. The World Kidney Day declares 2022 as the year of "Kidney Health for All" to promote global teamwork in advancing strategies in bridging the gap in kidney health education and literacy. Kidney organizations should work toward shifting the patient-deficit health literacy narrative to that of being the responsibility of health care providers and health policy makers. By engaging in and supporting kidney health-centered policy making, community health planning, and health literacy approaches for all, the kidney communities strive to prevent kidney diseases and enable living well with kidney disease.

[Kidney health for everyone everywhere - from prevention to detection and equitable access to care].

The global burden of chronic kidney disease (CKD) is rapidly increasing with a projection of becoming the 5th most common cause of years of life lost globally by 2040. Aggravatingly, CKD is a major cause of catastrophic health expenditure. The costs of dialysis and transplantation consume up to 3% of the annual healthcare budget in high-income countries. Crucially, however, the onset and progression of CKD is often preventable. In 2020, the World Kidney Day campaign highlights the importance of preventive interventions be it primary, secondary or tertiary. This complementing article focuses on outlining and analyzing measures that can beimplemented in every country to promote and advance CKD prevention. Primary prevention of kidney disease should focus on the modification of risk factors and addressing structural abnormalities of the kidney and urinary tracts, as well as exposure to environmental risk factors and nephrotoxins. In persons with pre-existing kidney disease, secondary prevention, including blood pressure optimization and glycemic control, should be the main goal of education and clinical interventions. In patients with advanced CKD, management of co-morbidities such as uremia and cardiovascular disease is a highly recommended preventative intervention to avoid or delay dialysis or kidney transplantation. Political efforts are needed to proliferate the preventive approach. While national policies and strategies for non-communicable diseases might be present in a country, specific policies directed toward education and awareness about CKD screening, management and treatment are often lacking. Hence, there is an urgent need to increase the awareness of the importance of preventive measures throughout populations, professionals and policy makers.

Chronic hyponatremia and association with osteoporosis among a large racially/ethnically diverse population.

Chronic hyponatremia may contribute to decreased bone density. We studied 341,003 men and women who underwent DXA testing and observed that individuals with chronic hyponatremia (sodium < 135 mEq/L) had an 11% greater likelihood of having osteoporosis. There was a dose-dependent effect with lower sodium and stronger association with osteoporosis. INTRODUCTION: Chronic hyponatremia has been associated with both neurologic deficits and increased risk of gait abnormalities leading to falls and resultant bone fractures. Whether chronic hyponatremia contributes to decreased bone density is uncertain. We evaluated whether chronic, mild hyponatremia based on serial sodium measurements was associated with increased risk of osteoporosis within a large, ethnically diverse population. METHODS: This is a retrospective cohort study between January 1, 1998 and December 31, 2014 within Kaiser Permanente Southern California, an integrated healthcare delivery system. Men and women were aged ≥ 55 years with ≥ 2 serum sodium measurements prior to dual-energy X-ray absorptiometry (DXA) testing. Time-weighted (TW) mean sodium values were calculated by using the proportion of time (weight) elapsed between sodium measurements and defined as < 135 mEq/L. Osteoporosis defined as any T-score value ≤ - 2.5 of lumbar spine, femoral neck, or hip. RESULTS: Among 341,003 individuals with 3,330,903 sodium measurements, 11,539 (3.4%) had chronic hyponatremia and 151,505 (44.4%) had osteoporosis. Chronic hyponatremic individuals had an osteoporosis RR (95% CI) of 1.11 (1.09, 1.13) compared to those with normonatremia. A TW mean sodium increase of 3 mEq/L was associated with a lower risk of osteoporosis [adjusted RR (95% CI) 0.95 (0.93, 0.96)]. A similar association was observed when the arithmetic mean sodium value was used for comparison. CONCLUSIONS: We observed a modest increase in risk for osteoporosis in people with chronic hyponatremia. There was also a graded association between higher TW mean sodium values and lower risk of osteoporosis. Our findings underscore the premise that chronic hyponatremia may lead to adverse physiological effects and responses which deserves better understanding.

Liquid metals: fundamentals and applications in chemistry.

Post-transition elements, together with zinc-group metals and their alloys belong to an emerging class of materials with fascinating characteristics originating from their simultaneous metallic and liquid natures. These metals and alloys are characterised by having low melting points (i.e. between room temperature and 300 °C), making their liquid state accessible to practical applications in various fields of physical chemistry and synthesis. These materials can offer extraordinary capabilities in the synthesis of new materials, catalysis and can also enable novel applications including microfluidics, flexible electronics and drug delivery. However, surprisingly liquid metals have been somewhat neglected by the wider research community. In this review, we provide a comprehensive overview of the fundamentals underlying liquid metal research, including liquid metal synthesis, surface functionalisation and liquid metal enabled chemistry. Furthermore, we discuss phenomena that warrant further investigations in relevant fields and outline how liquid metals can contribute to exciting future applications.

Evolution of 2D tin oxides on the surface of molten tin.

The exfoliation of two dimensional (2D) oxides, established on the surface of specific liquid metals, has recently been introduced. One such liquid metal is molten tin, which forms a variety of surface 2D oxides. However, the development behaviour of these surface tin oxides is still unknown. Here the evolution of stoichiometry and thickness from single-layer SnO to highly oxidised multi-layer SnO2 in ambient oxygen is explored.

Estimated glomerular filtration rate and the risk-benefit profile of intensive blood pressure control amongst nondiabetic patients: a post hoc analysis of a randomized clinical trial.

BACKGROUND: The Systolic Blood Pressure Intervention Trial (SPRINT; ClinicalTrials.gov, NCT01206062) reported reduced cardiovascular events by intensive blood pressure (BP) control amongst hypertensive patients without diabetes. However, the risk-benefit profile of intensive BP control may differ across estimated glomerular filtration rate (eGFR) levels. METHODS: This is a post hoc analysis of the SPRINT. Nondiabetic hypertensive adults (n = 9361) with eGFR >20 mL per min per 1.73 m2 were enrolled from 102 US facilities between November 2010 and March 2013 and were followed up until August 2015 (median follow-up, 3.26 years). Patients were randomly assigned to either a systolic BP target of <120 or <140 mmHg (for intensive or standard treatment, respectively). The outcomes of interests were the development of (i) fatal and nonfatal major cardiovascular events and (ii) acute kidney injury (AKI). RESULTS: The cardiovascular benefit from intensive treatment was attenuated with lower eGFR (Pinteraction  = 0.019), whereas eGFR did not modify the adverse effect on AKI (Pinteraction  = 0.179). Amongst 891 participants with eGFR <45 mL per min per 1.73 m2 , intensive treatment did not reduce the cardiovascular outcome (54/446 vs. 54/445 events in the standard group, respectively; hazard ratio [HR], 0.92; 95% CI, 0.62-1.38) with an absolute rate difference (ARD) of -0.02 (95% CI, -0.07 to +0.03) per 100 patient-years, whereas it increased AKI (62/446 vs. 38/445 events in the standard group; HR, 1.73; 95% CI, 1.12-2.66) with an ARD of +1.93 (95% CI, +1.88 to +1.97) per 100 patient-years. CONCLUSIONS: Intensive BP control may provide little or no benefit and even be harmful for patients with moderate-to-advanced chronic kidney disease.

Averting the legacy of kidney disease - focus on childhood.

World Kidney Day 2016 focuses on kidney disease in childhood and the antecedents of adult kidney disease that can begin in earliest childhood. Chronic kidney disease (CKD) in childhood differs from that in adults, in that the largest diagnostic group among children includes congenital anomalies and inherited disorders, with glomerulopathies and kidney disease as a consequence of diabetes being relatively uncommon. In addition, many children with acute kidney injury will ultimately develop sequelae that may lead to hypertension and CKD in later childhood or in adult life. Children born early or who are small-for-date newborns have relatively increased risk for the development of CKD later in life. Persons with a high-risk birth and early childhood history should be watched closely in order to help detect early signs of kidney disease in time to provide effective prevention or treatment. Successful therapy is feasible for advanced CKD in childhood; there is evidence that children fare better than adults, if they receive kidney replacement therapy including dialysis and transplantation, although only a minority of children may require this ultimate intervention. Because there are disparities in access to care, effort is needed so that children with kidney disease, wherever they live, may be treated effectively, irrespective of their geographic or economic circumstances. Our hope is that the World Kidney Day will inform the general public, policy makers and caregivers about the needs and possibilities surrounding kidney disease in childhood.

Evitar el legado de la enfermedad renal. Enfoque sobre la niñez / Averting the legacy of kidney disease. Focus on childhood

El Día Mundial del Riñón 2016 se centra en las enfermedades renales durante la infancia y la enfermedad renal del adulto que puede iniciarse en una edad temprana. La enfermedad renal crónica (ERC) en la infancia difiere de la de los adultos en que predominan las causas derivadas de anomalías congénitas y trastornos hereditarios; las glomerulopatías y la enfermedad renal asociada a diabetes mellitus son poco frecuentes. Además, muchos niños con una lesión renal aguda pueden desarrollar eventualmente secuelas que lleven a la hipertensión y la ERC durante la adolescencia o la vida adulta. Los niños nacidos prematuros o pequeños para su edad gestacional tienen un incremento del riesgo de desarrollar ERC durante su vida. Las personas con un alto riesgo al nacer o en la primera infancia deberán ser monitorizadas estrechamente para poder detectar a tiempo los signos tempranos de enfermedad renal, con el fin de proporcionar una prevención o un tratamiento efectivos. Es factible establecer una terapia eficaz en niños con ERC avanzada; existen evidencias que demuestran que los niños evolucionan mejor que los adultos cuando reciben terapia de reemplazo renal, incluyendo la diálisis y el trasplante, aunque sólo una minoría requiere este tratamiento. Debido a las inequidades en el acceso a la atención médica, es necesario hacer un esfuerzo para que los niños con una enfermedad renal, donde sea que vivan, puedan ser tratados de manera eficaz, independientemente de su ubicación geográfica y su situación económica. Nuestra esperanza es que el Día Mundial del Riñón pueda informar al público en general, a los gestores y a los profesionales de la salud sobre las necesidades y las posibilidades que existen en torno a la enfermedad renal en la infancia (AU)
