Smoking and Kidney Disease: Risk Factors, Challenges, and Preventive Strategies.

Contrib Nephrol 2021 Aug 3;199:1-9. Epub 2021 Aug 3.

Nephrology Department, University of São Paulo, São Paulo, Brazil.

Clinical Background: Although chronic kidney disease (CKD) and smoking are both associated with high rates of morbidity and mortality, the interplay between the two is not widely understood. Epidemiology: The incidence of CKD progression has been shown to be significantly higher among current and former smokers, and continued smoking thereafter has been associated with a nearly twofold higher risk of death. Challenges: Because it is a silent disease, CKD is often diagnosed in advanced stages, which underscores the importance of targeted, active screening for CKD. Read More

Stroke and Chronic Kidney Disease.

Contrib Nephrol 2021 Aug 3;199:1-11. Epub 2021 Aug 3.

Ottawa Hospital Research Institute, The Ottawa Hospital, Civic Campus, Ottawa, Ontario, Canada.

Chronic kidney disease (CKD) is strongly associated with the full spectrum of cerebrovascular disease including ischaemic and haemorrhagic stroke, small vessel disease, and vascular cognitive impairment. Shared conventional vascular risk factors such as age, hypertension, and diabetes mellitus may account for many of these associations, but novel renal-specific risk factors such as uraemia-related coagulopathy or endothelial dysfunction have also been proposed. In this chapter, we will explore the impact of CKD on stroke risk, mechanisms, and outcomes. Read More

Reasons for Disparities in Access to Kidney Transplantation.

Contrib Nephrol 2021 Aug 3;199:1-10. Epub 2021 Aug 3.

Santa Casa de Misericórdia de Porto Alegre, Porto Alegre, Brazil.

Clinical Background: Kidney transplantation (KT) is the best treatment for most patients with end-stage kidney disease (ESKD), providing better survival and quality of life and lower cost when compared to dialysis. Epidemiology: Despite robust evidence showing the superiority of KT over dialysis, a significant percentage of ESKD patients worldwide do not access this treatment. Challenges: Barriers resulting in inequalities and inequities in access to KT involves chronic kidney disease (CKD) diagnosis and management, including difficulties in accessing dialysis therapy before KT; suboptimal referral and enlistment to KT; and imbalance between supply and demand for organs.

Herbal Nephropathy.

Contrib Nephrol 2021 Aug 3;199:1-12. Epub 2021 Aug 3.

Departamento de Nefrología y Metabolismo Mineral, Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, Mexico City, Mexico.

An estimated one-third of adults in developed countries and more than 80% of the population in many low- and middle-income countries use herbal and traditional medicines to promote health or for the treatment of common diseases. Herbal medicines can cause kidney damage as a result of intrinsic toxicity, adulteration, contamination, replacement, misidentification, mistaken labeling, and unfavorable herb-drug interactions. The kidneys, due to their high blood flow rate, large endothelial surface area, high metabolic activity, active uptake by tubular cells, medullary interstitial concentration, and low urine pH are particularly vulnerable to development of toxic injury in the form of different syndromes like acute kidney injury, nephrolithiasis, chronic interstitial fibrosis, or uroepithelial cancer.

Religion, spirituality, and epilepsy.

Authors:
Ian Bone Simon Dein

Epilepsy Behav 2021 Jul 31;122:108219. Epub 2021 Jul 31.

Psychiatry and Anthropology, Queen Mary College, University of London, Consultant Psychiatrist Princess Alexandra Hospital, Harlow, Essex CM20 1QX UK.

This review provides responses to four questions on epilepsy, religion, and spirituality. Firstly, have early religious beliefs and writings stigmatized and discriminated against epilepsy and if so, what has been done to correct this? We provide textual evidence suggesting an affirmative response. Secondly, which religious luminaries, gods, saints, and religious symbols have connections with epilepsy? We argue that the evidence to suggest that St Paul, Joan of Arc, the Prophet Mohammed, and others had epilepsy is weak and emphasizes the limitations of imposing contemporary neurological frameworks upon them.

How strand exchange protein function benefits from ATP hydrolysis.

Curr Opin Genet Dev 2021 Jul 31;71:120-128. Epub 2021 Jul 31.

Department of Radiation and Cellular Oncology, University of Chicago, IL, USA; Department of Molecular Genetics and Cell Biology, University of Chicago, IL, USA. Electronic address:

Members of the RecA family of strand exchange proteins carry out the central reaction in homologous recombination. These proteins are DNA-dependent ATPases, although their ATPase activity is not required for the key functions of homology search and strand exchange. We review the literature on the role of the intrinsic ATPase activity of strand exchange proteins. Read More

Progress and prospects in mitigation of landfill leachate pollution: Risk, pollution potential, treatment and challenges.

J Hazard Mater 2021 Jul 12;421:126627. Epub 2021 Jul 12.

Ecosphere Resilience Research Center, Faculty of Applied Sciences, University of Sri Jayewardenepura, Nugegoda 10250, Sri Lanka. Electronic address:

The escalating loads of municipal solid waste (MSW) end up in open dumps and landfills, producing continuous flows of landfill leachate. The risk of incorporating highly toxic landfill leachate into environment is important to be evaluated and measured in order to facilitate decision making for landfill leachate management and treatment. Leachate pollution index (LPI) provides quantitative measures of the potential environmental pollution by landfill leachate and information about the environmental quality adjacent to a particular landfill.
