Propolis attenuates cobalt induced-nephrotoxicity in adult rats and their progeny

The aim of this study was to evaluate the biochemical changes in cobalt-exposed rats and to investigate the potential role of Tunisian propolis against the cobalt-induced renal damages. Twenty-four pregnant Wistar rats were divided into four groups and were treated as follows: group 1 (control) received distilled water; group 2 received 350 ppm of CoCl₂ in drinking water; group 3 received 350 ppm CoCl₂ in drinking water and a propolis-supplemented diet (1 g/100 g of diet); group 4 received a propolis-supplemented diet (1 g/100 g of diet) without cobalt. In the cobalt group, a significant decrease in body, absolute and relative weights was noted when compared to controls. The administration of cobalt to pregnant rats from the 14th day of pregnancy until day 14 after delivery resulted in an increased level of renal malondialdehyde, a decreased renal content of glutathione and antioxidant enzyme activities such as superoxide dismutase, catalase and glutathione peroxidase in lactating rats and their pups. A statistically significant increase in plasma urea and creatinine serum levels was seen in treated female rats and their pups. Histopathologically, the cobalt-administration induced degenerative changes in the kidney of lactating rats and their pups. When compared with cobalt-treated rats, those receiving the propolis supplementation (along with cobalt-treatment) had lower malondialdehyde levels, higher antioxidant activities and the cobalt-related histopathological changes in the kidneys were at lower severity.Our results suggested that the propolis might be a potential candidate agent against cobalt-induced nephrotoxicity in adult and juvenile rats when administered to female rats during the late pregnancy and the early postnatal period.     

Trace element status and fatty acids metabolism during healthy ageing: an example of a population from the Tunisian eastern coast

Micronutrients as well as essential fatty acids are indispensable for the correct functioning of the organism. The risk of disturbance in the associated nutrition and metabolism is expected to increase during ageing. In addition, it seems that trace elements are involved in the fatty acids metabolism. The aim of the present study was then to assess age-related changes in trace elements status and in plasma essential fatty acids composition with an emphasis on the desaturase activity estimation. Two hundred healthy Tunisian subjects (30-85 years old) were recruited and separated into two subgroups: elderly (65-85 years old) and middle-aged (30-60 years old). The findings revealed that plasma zinc and calcium concentrations significantly decreased according to age. The prevalence of zinc deficiency was therefore shown to increase in old age (over 60% of elderly subjects were deficient or at risk of deficiency). No age-related changes were obtained for copper or magnesium status. The Δ6 desaturase, involved in the EFAs conversion, was shown to decrease according to age and to be associated with the plasma zinc level. Since elderly subjects were at risk of nutritional imbalance, it would be interesting to set optimal dietary proportion. This will help to prevent age-associated alterations and diseases for a better and healthy ageing.     

TSP1 and MMP9 genetic variants in sporadic prostate cancer

Angiogenesis plays an important role in the initiation and progression of many malignancies including prostate cancer (PCa). Therefore, genes implicated in angiogenic pathways could be susceptibility candidate genes for this malignancy. In this respect, we investigated the impact of functional genetic variants of TSP1 (N700S) and MMP9 (-1562 C/T) genes on the development and progression of PCa. This case-control study included 101 PCa patients and 106 healthy controls analyzed by polymerase chain reaction -restriction fragment length polymorphism assay. No association was observed between any of the TSP1 genotypes and PCa risk or severity; however, subjects carrying one copy of the MMP9 T allele exhibited threefold higher risk of developing PCa (OR = 2.86; P = 0.004). Regarding prognostic value, a significant association was found between the occurrence of the MMP9 T allele and the high-grade tumor (OR = 3.21; P = 0.004) and the advanced disease (OR = 2.47; P = 0.026). We also analyzed the effect of the combined genotypes on PCa risk. The patients with two high-risk genotypes exhibited 2.8-fold higher risk of developing PCa than those with only low-risk genotypes, but the association was not statistically significant. These findings suggest that MMP9 polymorphism is an independent risk factor of PCa development and aggressiveness.     

Does hospital ownership influence hospital referral region health rankings in the United States

Extensive evidence demonstrates that a hospital's organizational ownership structure impacts its overall performance, but little is known concerning the influence of hospital structure on the health of its community. This paper explores the association between US hospital referral region (HRR) health rankings and hospital ownership and performance. Data from the 2016 Commonwealth Fund Scorecard on Local Health System Performance, the American Hospital Association dataset, and the Hospital Value‐Based Purchasing dataset are utilized to conduct a cross‐sectional analysis of 36 quality measures across 306 HRRs. Multivariate regression analysis was used to estimate the association among hospital ownership, system performance measures—access and affordability, prevention and treatment, avoidable hospital use and cost, and healthy lives—and performance as measured by value‐based purchasing total performance scores. We found that indicators of access and affordability, as well as prevention and treatment, were significantly associated across all 3 hospitals' organizational structures. Hospital referral regions with a greater number of not‐for‐profit hospitals demonstrated greater indications of access and affordability, as well as better prevention and treatment rankings than for‐profit and government hospitals. Hospital referral regions with a greater number of government, nonfederal hospitals had worse scores for healthy lives. Furthermore, the greater the total performance scores score, the better the HRR score on prevention and treatment rankings. The greater the per capita income, the better the score across all 4 dimensions. As such, this inquiry supports the assertion that performance of a local health system is dependent on its community's resources of health care delivery entities and their structure.     

Hydatid Cyst of Bone: Diagnosis and Treatment

Osseous hydatidosis is a rare occurrence of hydatid disease. Anatomoclinical changes are, however, peculiar to this localization. From the anatomopathologic standpoint, this localization marks the torpid, insidious progression of the parasite into bone tissue, leading to an immediate diffuse, extensive, invasion process, so complete surgical eradication is rarely possible. From the clinical standpoint, whatever the localization may be, we are surprised by the latency of this affection, the patient being treated at an advanced stage, when radiologic lesions are already extensive, and the complications, especially in the spinal area, are severe. Owing to the poor biologic findings, the diagnosis of osseous hydatidosis is still primarily based on roentgenographic findings. Sometimes, however, the diagnosis is established only after surgery. Treatment of osseous hydatidosis is closer to oncologic therapy than to the usual surgical treatment of visceral hydatid cysts. Because of the poor results with medical treatment, osseous hydatidosis must be treated by a radical operation with wide excision, adapted to each localization. In the main, the prognosis of osseous hydatidosis remains poor, especially with spinal and pelvic localizations, which are the most frequent ones. The prognosis and treatment of osseous hydatidosis belong in the same category as a locally malignant lesion.     

Evaluation of enzymatic biomarkers and lipoperoxidation level in Hediste diversicolor exposed to copper and benzo[a]pyrene

This study aims to evaluate the effects of exposure to copper, benzo[a]pyrene, and to their mixture on enzymatic and lipid peroxidation biomarkers in Hediste diversicolor. Worms were submitted to 1 μM of both single compounds and to their mixture during a period of test of 12, 24, 36, and 48 h. The biomarkers selected in this work were the activities of cytochrome P450-dependent NADPH cytochrome c reductase (NADPH red) as phase I enzyme, glutathione-S-transferase (GST) as phase II enzyme, and the acetylcholinesterase (AChE) activity as neurotoxicity marker. Oxidative stress was evaluated using catalase activity (CAT) and malondialdehyde accumulation (MDA). The NADPH red activity was not significantly affected by copper exposure; it shows a drastic increase in both B[a]P and mixture-exposed organisms. GST activities were significant in B[a]P-exposed worms only after 36 h, and in animals exposed to the mixture after 12 and 48 h. The ACHE activity was inhibited only in B[a]P-exposed worms.     

Does level of minority presence and hospital reimbursement policy influence hospital referral region health rankings in the United States

The shift from a fee‐for‐service payment to a value‐based payment scheme, sparked by the Patient Protection and Affordable Care Act, introduced pay‐for‐performance programs such Hospital Value Based Purchasing. Previous inquiry has not considered how local community factors may affect hospital system performance. This study investigated the association between local health performance and minority population in a hospital referral region (HRR). The primary objective was to ascertain whether community diversity levels are significantly associated to local health performance guided by the ecological model. Secondary data analysis collected from the 2016 American Hospital Association, Area Health Resource File, Commonwealth Fund Scorecard on Local Health System Performance, and the Dartmouth Atlas HRR dataset was used. Our primary findings show that the more diverse a HRR is, the more likely it is to be associated with lower ranking for access and affordability prevention and treatment avoidable hospital use and cost as well as healthy lives. Total performance score was significantly related to a better health ranking on prevention and treatment, hospital use, and cost, as well as healthy lives. This research supports the assertion that communities, particularly minorities in those communities, affect local health care performance in a variety of ways.     

Sperm quality improvement after date seed oil in Vitro supplementation in spontaneous and induced oxidative stress

In vitro supplementation with date seed oil （DSO） can protect spermatozoa against hydrogen peroxide （HiO2）- mediated damage and can improve sperm function, possibly owing to antioxidant properties. We tested the antioxidant effects of DSO on human sperm motility, sperm viability, reacted acrosome and lipid peroxidation assessed in vitro after H202-mediated oxidative damage in spermatozoa. Sixteen patients （mean age： 35 years; range： 25-45 years） referred to the Histology-Embryology Laboratory of the Medicine Faculty of Sfax for semen analysis after 12-24 months of sexual intercourse without conception were selected. After spermiogram, sperm selection by twointerface discontinuous Sill Select gradient was performed, and selected spermatozoa were used in four experimental assays： control; incubation with 100um H2O2; incubation with 0.1% DSO; and co-incubation with 0.1% DSO and 100 um H2O2. Motility and viability were determined using World Health Organization criteria. Acrosome reaction and lipid peroxidation were assessed by staining with fluorescein isothiocyanate-Pisum sativum and spectrophotometric measurement of malondialdehyde, respectively. Results showed that incubation with H2O2 alone led to a significant increase in lipid peroxidation （57.83%, P 〈 0.05） associated with a significant decrease in sperm motility, sperm viability （after 30 min and 24 h） and percentage of reacted acrosome （P 〈 0.05）. Date seed oil im- proved sperm motility after 24 h of incubation （P 〈 0.05） and protected spermatozoa against the deleterious effects of H2O2 on motility, viability, acrosome reaction and lipid peroxidation. We conclude that supplementation with DSO may have a function in antioxidant protection against male infertility.
