Abstract
Parasitic agents have been known to cause human disease since ancient times and are endemic in tropical and subtropical regions. Complications of parasitic diseases, including kidney involvement, are associated with worse outcomes. Chagas disease, filariasis, leishmaniasis, malaria and schistosomiasis are important parasitic diseases that can damage the kidney. These diseases affect millions of people worldwide, primarily in Africa, Asia and Latin America, and kidney involvement is associated with increased mortality. The most common kidney complications of parasitic diseases are acute kidney injury, glomerulonephritis and tubular dysfunction. The mechanisms that underlie parasitic disease-associated kidney injury include direct parasite damage; immunological phenomena, including immune complex deposition and inflammation; and systemic manifestations such as haemolysis, haemorrhage and rhabdomyolysis. In addition, use of nephrotoxic drugs to treat parasitic infections is associated with acute kidney injury. Early diagnosis of kidney involvement and adequate management is crucial to prevent progression of kidney disease and optimize patient recovery.

Abstract
BackgroundDasapatrachurnam (DPC), a multicurative powder prepared from the leaves of 10 green leafy vegetables, was developed recently with known ethnobotanical and ethnopharmacological significance. However, its functional role in curing a disease is not yet scientifically proven. The present study aims at performing the phytochemical screening of DPC and exploring its possible activity as bacteriostatic, antineoplastic and anti-inflammatory. MethodsWe performed qualitative and Fourier transform infrared spectroscopy (FTIR) to find out the presence of active compounds and tested the bacteriostatic activity in four bacterial strains namely Bacillus subtilis, Escherichia coli, Streptococcus pyogenes and Staphylococcus aureus by agar well diffusion method. We further explored the antineoplastic activity in vitro in C6 and HEK293 cell lines by cell viability assay and the anti-inflammatory activity in the ovalbumin-induced inflammation in male Wistar rats. ResultsDPC showed 60% solubility in PBS and showed the presence of flavonoids and glycosides. FTIR results indicated the presence of alkyl, ketone and aldehyde groups. The bacteriostatic activity of DPC was higher (60%) in E.coli and lower (8%) in S.aureus, when compared to streptomycin. The anti-cancerous activity of DPC in C6 and HEK293 cancer cells was similar to their respective positive controls, curcumin and camptothecin. The anti-inflammatory activity of DPC was more evident with local administration in all the parameters studied in brain hippocampus, kidney, liver and spleen in ovalbumin-induced rats. ConclusionOur results, for the first time, suggest the potentiality of the DPC in treating bacterial diseases, cancer and also inflammation. Our results also suggest the possible therapeutic role of DPC in treating chronic kidney disease.

Hydration in relation to water insecurity, heat index, and lactation status in two small-scale populations in hot-humid and hot-arid environments. Am J Hum Biol 2020; 33:e23447. [PMID: 32583580 DOI: 10.1002/ajhb.23447] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 05/06/2020] [Accepted: 05/11/2020] [Indexed: 12/21/2022] Open
Abstract
OBJECTIVES This study compared the prevalence of concentrated urine (urine specific gravity ≥1.021), an indicator of hypohydration, across Tsimane' hunter-forager-horticulturalists living in hot-humid lowland Bolivia and Daasanach agropastoralists living in hot-arid Northern Kenya. It tested the hypotheses that household water and food insecurity would be associated with higher odds of hypohydration. METHODS This study collected spot urine samples and corresponding weather data along with data on household water and food insecurity, demographics, and health characteristics among 266 Tsimane' households (N = 224 men, 235 women, 219 children) and 136 Daasanach households (N = 107 men, 120 women, 102 children). RESULTS The prevalence of hypohydration among Tsimane' men (50.0%) and women (54.0%) was substantially higher (P < .001) than for Daasanach men (15.9%) and women (17.5%); the prevalence of hypohydration among Tsimane' (37.0%) and Daasanach (31.4%) children was not significantly different (P = .33). Multiple logistic regression models suggested positive but not statistically significant trends between household water insecurity and odds of hypohydration within populations, yet some significant joint effects of water and food insecurity were observed. Heat index (2°C) was associated with a 23% (95% confidence interval [CI]: 1.09-1.40, P = .001), 34% (95% CI: 1.18-1.53, P < .0005), and 23% (95% CI: 1.04-1.44, P = .01) higher odds of hypohydration among Tsimane' men, women, and children, respectively, and a 48% (95% CI: 1.02-2.15, P = .04) increase in the odds among Daasanach women. Lactation status was also associated with hypohydration among Tsimane' women (odds ratio = 3.35, 95% CI: 1.62-6.95, P = .001). CONCLUSION These results suggest that heat stress and reproductive status may have a greater impact on hydration status than water insecurity across diverse ecological contexts.

Rosinger AY. Biobehavioral variation in human water needs: How adaptations, early life environments, and the life course affect body water homeostasis. Am J Hum Biol 2019; 32:e23338. [PMID: 31631450 DOI: 10.1002/ajhb.23338] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2019] [Revised: 08/15/2019] [Accepted: 09/17/2019] [Indexed: 01/22/2023] Open
Abstract
Body water homeostasis is critical for optimal physiological and cognitive function for humans. The majority of research has illustrated the negative biological consequences of failing to meet water needs. The human body has several mechanisms for detecting, regulating, and correcting body water deficits and excesses. However, variation exists in total water intake and how people meet those water needs as well as thirst thresholds and how well people tolerate water restriction. An evolutionary and developmental framework provides an underexplored perspective into human water needs by examining how adaptations, early life experiences and environments, as well as life course changes in health states and behaviors may shape these critical factors in body water homeostasis. This article first reviews biological and behavioral adaptations to water scarcity among animals and humans. It then examines human variation in water intake in a mostly water secure environment through the analysis of National Health and Nutrition Examination Survey dietary data and the link between water intake patterns and hydration biomarkers. Next, it reviews existing evidence of how maternal water restriction in utero and during lactation shape vasopressin release, thirst thresholds, drinking patterns, and body water homeostasis for the infant. Early life water restriction appears to have implications for hydration status, body size, and cardiovascular health. Finally, it examines how life course changes in health states and behaviors, including obesity, sleep, and parasitic infection, affect body water homeostasis. This article poses new questions about the plasticity and shaping of human water needs, thirst, and hydration behaviors.
