REVIEW
M M Akhtar, P M Elliott
Anderson-Fabry disease is an X-linked lysosomal storage disorder caused by mutations in the GLA gene that result in deficiency of the enzyme alpha-galactosidase A. The worldwide incidence of Fabry's disease is reported to be in the range of 1 in 40,000-117,000, although this value may be a significant underestimate given under recognition of symptoms and delayed or missed diagnosis. Deficiency in alpha-galactosidase A causes an accumulation of neutral glycosphingolipids such as globotriaosylceramide (Gb3) in lysosomes within various tissues including the vascular endothelium, kidneys, heart, eyes, skin and nervous system...

OBJECTIVES: The authors aimed to analyze temporal trends in cardiac stress testing in U.S. Medicare beneficiaries from 2008 to 2012, types of stress testing, and comparative utilization related to the presence and severity of chronic kidney disease (CKD). BACKGROUND: A long-held perception depicts patients with CKD as being treated less intensively for cardiovascular disease than nonrenal patients. We wondered whether use of diagnostic testing for ischemic heart disease is affected by the presence of CKD...

Exosomes are extracellular vesicles that express self-antigens (SAgs) and donor human leukocyte antigens. Tissue-specific exosomes can be detected in the circulation following lung, heart, kidney and islet cell transplantations. We collected serum samples from patients who had undergone lung (n=30), heart (n=8), or kidney (n=15) transplantations to isolate circulating exosomes. Exosome purity was analyzed by Western blot, using CD9 exosome-specific markers. Tissue-associated lung SAgs, collagen V (Col-V) and K-alpha 1 tubulin (Kα1T), heart SAgs, myosin and vimentin, and kidney SAgs, fibronectin and collagen IV (Col-IV), were identified using western blot...

A female in her late teens purposely ingested alcohol fuel containing methanol to commit suicide, which she admitted on social media. She was found in distress by her parents and died at the hospital some hours later. Autopsy revealed swelling of the brain and edematous and congestive lungs. No other trauma or unusual findings were revealed at autopsy. Methanol was detected upon routine screening for alcohols by headspace gas chromatography with flame-ionization detection. To confirm the presence of methanol and its metabolite formic acid, a method with detection by mass spectrometry was used...

WHAT IS KNOWN AND OBJECTIVE: Angiotensin converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB) represent the cornerstones of hypertension and congestive heart failure treatment. Risk factors for hyperkalaemia associated with ACEI and ARB are chronic kidney disease and concomitant medications which increase serum potassium level. Body mass index (BMI) also affects pharmacokinetics of ACEI and ARB and potassium disposition. We evaluated the relationship between BMI and hyperkalaemia associated with ACEI and ARB treatments...

PURPOSE: SMARCB1 encodes a subunit of the SWI/SNF complex involved in chromatin remodeling. Pathogenic variants (PV) in this gene can give rise to three conditions. Heterozygous loss-of-function germline PV cause rhabdoid tumor predisposition syndrome and schwannomatosis. Missense PV and small in-frame deletions in exons 8 and 9 result in Coffin-Siris syndrome, which is characterized by intellectual disability (ID), coarse facial features, and fifth digit anomalies. METHODS: By a gene matching approach, individuals with a similar SMARCB1 PV were identified...

We previously discovered that oral treatment with AC261066, a synthetic selective agonist for the retinoic acid β2-receptor (RARβ2), decreases oxidative stress in the liver, pancreas, and kidney of mice fed a high-fat diet (HFD). Since hyperlipidemic states are causally associated with myocardial ischemia and oxidative stress, we have now investigated the effects of AC261066 in an ex-vivo ischemia/reperfusion (I/R) injury model in hearts of two prototypic dysmetabolic mice. We found that a 6-week oral treatment with AC261066 in both genetically hypercholesterolemic (ApoE-/-) and obese (HFD-fed) wild-type mice exerts protective effects when their hearts are subsequently subjected to I/R ex vivo in the absence of added drug...

BACKGROUND: Understanding the correlates of self-rated health (SRH) can help public health professionals prioritize health-promotion and disease-prevention interventions. This study aimed to investigate the association between multiple comorbidities and global SRH and age-comparative SRH. METHODS: A total of 512,891 participants aged 30-79 years old were recruited into the China Kadoorie Biobank study from ten regions between 2004 and 2008. Multivariate logistic regression models were used to estimate the odds ratios (ORs) for the associations between comorbidities (including diabetes, hypertension, coronary heart disease, rheumatic heart disease, stroke, tuberculosis, emphysema/bronchitis, asthma, cirrhosis/chronic hepatitis, peptic ulcer, gallbladder disease, kidney disease, fracture, rheumatic arthritis, psychiatric disorders, depressive symptoms, neurasthenia, head injury and cancer) and SRH...

Ageing affects various physiological and metabolic processes in a body and a progressive accumulation of oxidative damage stands out as often used explanation. One of the most powerful scavenger of reactive oxygen species (ROS) in all organs is melatonin. A majority of melatonin supplied to the body via blood originates from the pineal gland. However, we have been interested in a locally produced melatonin. We have used 2.5- and 36-months-old Wistar rats. Tissues were collected and gene expression of AA-NAT and ASMT, the two key enzymes in a synthesis of melatonin, was determined in brain, liver, kidney, heart, skin, and intestine...

The G-protein-coupled receptor kinase 2 (GRK2) plays a major role in cardiovascular diseases and its expression is increased in heart failure. However, only little is known about factors being involved in up-regulation of GRK2 expression through transcriptional regulation of its promoter. Since the transcription factor early-growth response 1 (EGR-1) is also up-regulated in patients with heart failure, we tested the hypothesis that EGR-1 regulates GRK2 transcription. Stimulation of immortalized rat cardiomyocytes (H9c2) with phorbol 12-myristate 13-acetate (PMA) resulted in up-regulation of Egr-1 and subsequently of Grk2 mRNA expression, with maximum Grk2 expression (p=0...

Triangular Ag nanoplates with a thickness of 5 nm and tunable edge lengths were fabricated using a seed-mediated protocol, featuring enhanced near-infrared absorption as the edge length of nanoplates increased. The photoacoustic (PA) efficiency of these Ag nanoplates were assessed. Nanoplates with an edge length of 100 nm (r1) performed best among others in the in vitro assessment. In the following in vivo test, r1 nanoplates were also found to boost the PA signal of tumor vessels, while a detailed PA imaging of tumor vasculature was obtained...

Proteinuric kidney disease, especially in the early and middle stages of renal insufficiency, may be favorably affected by ACE-I/ARB. The progression of renal insufficiency is thereby slowed down and dialysis obligation occurs later or can even be avoided. This effect is independent of the underlying glomerular kidney disease. In the advanced stage of renal insufficiency, the benefit of ACE-I/ARB cannot yet be conclusively assessed. The interruption of ACE-I/ARB therapy may possibly contribute to a certain recovery of renal function and delay the onset of dialysis a little...

Women with hypertensive pregnancy complications are at greater risk of developing cardiovascular disease (CVD), metabolic diseases, stroke, and end-stage renal disease later in life. Pregnancy complications not only effect the mother's long-term health, but also the health of the fetus immediately after delivery and into adulthood. The health of the fetus until adulthood can be influenced by developmental programming, in which the fetus is exposed to insults that will ultimately affect the growth of the offspring and increase the offspring's risk of developing hypertension, coronary heart disease, metabolic disease, and chronic kidney disease in adulthood...

Traditional quantitative and qualitative research methods inadequately capture the complexity of patients' daily self-management. Contextual inquiry methodology, using home visits, allows a more in-depth understanding of how patients integrate immunosuppressive medication intake, physical activity and healthy eating in their daily lives, and which difficulties they experience when doing so. This mixed-method study comprised two home visits in 19 purposively selected adult heart, lung, liver and kidney transplant patients, asking them to demonstrate how they implement the aforementioned health behaviours...
