Cardiovascular Health in Migrants. Current status and issues for prevention. A Collaborative Multidisciplinary Task Force Report
2014
OBJECTIVES: To review information on cardiovascular health and migration, to stress the attention of researchers that much needs to be done in the collection of sound data in Italy and to allow policy makers identifying this issue as an important public health concern. BACKGROUND: In Italy, the rate of immigrants in the total number of residents increased from 2.5% in 1990 to 7.4% in 2010, and currently exceeds 10% in regions such as Lombardia, Emilia Romagna and Toscana. METHODS: A consensus statement was developed by approaching relevant Italian national scientific societies involved in cardiovascular prevention. Task force members were identified by the president and/or the boards of eac…
Renal function is impaired in normotensive chronic HCV patients: role of insulin resistance.
2015
Renal dysfunction is an independent predictor for cardiovascular morbidity and mortality. We investigated whether chronic hepatitis C virus (HCV) infection and the related insulin resistance/hyperinsulinemia influence renal function in comparison with a group of healthy subjects and with another group with metabolic syndrome. We enrolled 130 newly diagnosed HCV outpatients matched for age and gender with 130 patients with metabolic syndrome and 130 healthy subjects. Renal function was evaluated by calculation of glomerular filtration rate (e-GFR, mL/min/1.73 m2) using the CKD-EPI equation. The following laboratory parameters were measured: fasting plasma glucose and insulin, total, LDL- and…
A randomized multicenter trial on a lung ultrasound-guided treatment strategy in patients on chronic hemodialysis with high cardiovascular risk
2021
Lung congestion is a risk factor for all-cause and cardiovascular mortality in patients on chronic hemodialysis, and its estimation by ultrasound may be useful to guide ultrafiltration and drug therapy in this population. In an international, multi-center randomized controlled trial (NCT02310061) we investigated whether a lung ultrasound-guided treatment strategy improved a composite end point (all-cause death, non-fatal myocardial infarction, decompensated heart failure) vs usual care in patients receiving chronic hemodialysis with high cardiovascular risk. Patient-Reported Outcomes (Depression and the Standard Form 36 Quality of Life Questionnaire, SF36) were assessed as secondary outcome…
Kardiovaskulārā riska izvērtējums pacientiem ar nieres transplantātu
2022
Viens no biežākajiem nāves iemesliem pacientiem ar funkcionējošu nieres transplantātu ir kardiovaskulāri (KV) notikumi. Lai savlaicīgi varētu veikt preventīvu ārstēšanu un uzlabot nieres transplantāta recipientu dzīvildzi, ir nozīmīgi izvērtēt svarīgākos KV riska faktorus un to ietekmi uz KV notikumu attīstību. Retrospektīva pētījuma mērķis bija izvērtēt KV notikumu incidenci, riska faktorus un nieres transplantācijas (NT) iznākumus pacientiem ar KV notikumiem. Pētījumā tika iekļauti 184 pacienti. Datu analīzei pacienti tika sadalīti divās grupās: pacienti ar KV notikumiem un pacienti bez KV notikumiem. Glomerulārās filtrācijas ātrums tika aprēķināts pēc CKD-EPI Creatinine, 2021 formulas. R…
Unethical Brotherly Love: Zell Kravinsky and Maximum Human Utility
2014
The case of American investor and philanthropist Zell Kravinsky (1956-) presents numerous ethical challenges regarding our social responsibility to others. In 2003, after disbursing the bulk of his forty-five-million-dollar fortune to various charities, Kravinsky made the decision to donate one of his kidneys to an impoverished African-American woman he had met only once. In doing so he courageously saved a life, but also incurred the wrath of his family, friends, and many observers in the media who questioned his sanity. To Kravinsky, however, refusal to donate would have been tantamount to murder, constituting a violation of his belief in ‘maximum human utility’ – a concept that insists o…
Isolation From Human Calcium Oxalate Renal Stones of Nephrocalcin, a Glycoprotein Inhibitor of Calcium Oxalate Crystal Growth. Evidence That Nephroca…
1987
We have determined that the organic matrix of calcium oxalate kidney stones contains a glycoprotein inhibitor ofcalcium oxalate crystal growth (nephrocalcin) that resembles nephrocalcin present in the urine of patients with calcium oxalate stones and differs from nephrocalcin from the urine of normal people. Pulverized calcium oxalate renal stones were extracted with 0.05M EDTA, pH 8.0; nephrocalcin eluted in five peaks using DEAE-cellulose column chromatography, and each peak was further resolved by Sephacryl S-200 column chromatography. Four ofthe fiveDEAE peaks corresponded to those usually found in nephrocalcin from urine; the fifth eluted at a lower ionic strength than any found in uri…
Deoxyribonucleases in Herpes simplex Virus Type 1 and 2 Infected Primary Rabbit Kidney Cells
1980
Abstract In primary rabbit kidney cells infected with herpes simplex virus four different neutral deoxyribonuclease activities can be detected by means of the deoxyribonuclease assay in DNA-containing polyacrylamide gels following their separation by discelectrophoresis. The method is suitable to follow independently the change in each activity of the different enzymes using only about 5 × 105 cells for each assay during the time-course of infection. Under these conditions one enzyme activity is constant, two disappear while the activity of a fourth one present only in infected cells, increases.
EFFECTS OF CYCLOPROPENOID FATTY ACIDS (BAOBAB SEED OIL) ON THE FATTY ACID PROFILE OF LIPIDS FROM DIFFERENT TISSUES IN THE RAT
1996
Rats were fed for 8 weeks a diet containing either Baobab seed oil (FBO) rich in cyclopropenoid fatty acids (CPFA) or heated oil (HBO) devoid of CPFA. In FBO rats, compared to controls (CO), the monounsaturated fatty acid content of adipose tissue lipids, liver triacylglycerols, liver and adrenal cholesteryl esters and liver, kidney, adrenal phospholipids were highly decreased to the benefit of saturated fatty acid content. In cholesteryl esters and phospholipids, the arachidonic acid (20:4 n-6) content was markedly decreased, especially in adrenals. In adrenal cholesteryl esters, adrenic acid (22:4 n-6) content was decreased more than its precursor. The effects of HBO on the tissue lipid f…
Effects of testosterone and β-glucan on immune functions in tench
2005
A hormone manipulation was performed to examine the effects of testosterone on basal and β-glucan-induced immune functions in wild-caught male and female tench Tinca tinca. Testosterone administration elevated testosterone concentration in plasma, but did not suppress lytic activity of plasma or the chemiluminescence response of blood or head kidney phagocytes in any of the three successive samples or in any of the treatment groups. Both testosterone and β-glucan administrations had a negative effect on the relative mass of the spleen, and testosterone-treated fish lost more mass than control fish. Males had a relatively larger spleen than females, but there were no gender differences in im…
