Abstract Vitally essential red fluids like packed cells and red wine are seriously influenced in quality when stored over prolonged periods. In the case of red cell concentrates, the resulting storage lesion has particular significance in perioperative medicine. We hypothesized that, in contrast, aging rather improves the properties of red wine in several ways. A translational approach, including (I) in vitro experiments, (II) a randomized, blinded crossover trial of acute clinical effects, and (III) a standardized red wine blind tasting was used. Three monovarietal wines (Cabernet Sauvignon, Chianti, Shiraz) in three different vintages (range 2004–2016), each 5 years different, were assessed. Assessments were performed at a German university hospital (I, II) and on a garden terrace during a mild summer evening (III). Young wines induced cell stress and damage while significantly reducing cytoprotective proteins in HepG2 hepatoma cells. Sympathetic activity and multitasking skills were altered depending on wines’ ages. Hangovers tended to be aggravated by young red wine. Aged variants performed better in terms of aroma and overall quality but worse in optical appearance. We found no evidence for a red wine storage lesion. However, we plead for consensus-based guidelines for proper storage, as it is common in clinical medicine.

<p style="text-align: justify;">Several observations suggest that wine consumption could have beneficial effects on health by preventing cardiovascular diseases. Apparently, ethanol is not the only component responsible for these effects, phenolic substances: tanins, flavonoids may have an important role. As these compounds are able to affect biological membranes, we investigated the effect of wine <em>in vitro</em> on two model membranes: the lysosomal membrane and the red cell membrane. The integrity of rat liver lysosomal membrane was assessed by measuring the latency of Nacetylglucosaminidase, a lysosomal enzyme, when the organelles are subjected to free radicals of oxygen in the presence of different concentrations of wine. The state of red cell membrane was followed by determining hemolysis caused by phospholipase C. Our results show that low concentrations of red wine prevent the deterioration of the membrane of lysosomes induced by oxygen free radicals generated by the xanthine-xanthine oxidase system and oppose hemolysis induced by treating red cells with <em>Clostridium welchii</em> phospholipase C. White wine is considerably less efficient. As similar effects can be obtained with some phenolic compounds, it is probable that the membrane protective effects of red wine that we describe, originate from its content in these substances.</p>

Storage of erythrocytes in blood banks is associated with biochemical and morphological changes to RBCs (red blood cells). It has been suggested that these changes have potential negative clinical effects characterized by inflammation and microcirculatory dysfunction which add to other transfusion-related toxicities. However, the mechanisms linking RBC storage and toxicity remain unclear. In the present study we tested the hypothesis that storage of leucodepleted RBCs results in cells that inhibit NO (nitric oxide) signalling more so than younger cells. Using competition kinetic analyses and protocols that minimized contributions from haemolysis or microparticles, our data indicate that the consumption rates of NO increased ~40-fold and NO-dependent vasodilation was inhibited 2–4-fold comparing 42-day-old with 0-day-old RBCs. These results are probably due to the formation of smaller RBCs with increased surface area: volume as a consequence of membrane loss during storage. The potential for older RBCs to affect NO formation via deoxygenated RBC-mediated nitrite reduction was also tested. RBC storage did not affect deoxygenated RBC-dependent stimulation of nitrite-induced vasodilation. However, stored RBCs did increase the rates of nitrite oxidation to nitrate in vitro. Significant loss of whole-blood nitrite was also observed in stable trauma patients after transfusion with 1 RBC unit, with the decrease in nitrite occurring after transfusion with RBCs stored for >25 days, but not with younger RBCs. Collectively, these data suggest that increased rates of reactions between intact RBCs and NO and nitrite may contribute to mechanisms that lead to storage-lesion-related transfusion risk.

ABSTRACT Red cells were incubated in vitro with sulfhydryl inhibitors and Rhantibody with and without prior incubation with prednisolone-hemisuccinate. These erythrocytes were labelled with Cr51 and P32 and their disappearance in vivo after autotransfusion was measured. Prior incubation with prednisolone-hemisuccinate had no effect on the rate of red cell disappearance. The disappearance of the cells was shown to take place without appreciable intravascular destruction.

ABSTRACT The red cell triiodothyronine uptake technique as used in our hospital is described. Incubation time is of almost no importance. The temperature during incubation should be 37° C. Further improvement of the technique is obtained when all blood samples are brought up to 40 % haematocrit prior to incubation. Clinical results are discussed. It is yet too early to give a definite assessment of its clinical value, but it is definitely superior to the measurement of the BMR.

Short Term Treatment

Bone metastases are a major source of morbidity in patients with cancer. Previously, we found that gallium nitrate was a highly effective treatment for cancer-related hypercalcemia. Laboratory studies have shown that this drug inhibits bone resorption in vitro and that short-term treatment in vivo increases the calcium content of bone. We evaluated the clinical effects of gallium nitrate on biochemical parameters of increased bone turnover in 22 patients with bone metastases. Treatment with gallium nitrate for five to seven days caused a median reduction in 24-hour urinary calcium excretion of 66% relative to baseline measurements (P less than .01). Hydroxyproline (OHP) excretion was also significantly reduced (P less than .01). The greatest reduction in hydroxyprolinuria occurred in patients with high baseline excretion. Ionized serum calcium and serum phosphorous declined significantly after treatment (P less than .01 for each). Serum immunoreactive parathyroid hormone (PTH) increased significantly (P less than .01), as did serum levels of 1,25 (OH)2-vitamin D3 (P less than .05). Urinary phosphorous excretion and serum levels of 25-OH-vitamin D3 were not significantly changed. No major toxic reactions occurred as a result of this treatment. These results indicate that gallium nitrate significantly reduces biochemical parameters associated with accelerated bone turnover and that this agent may be useful for preventing pathologic conditions associated with bone metastases.

Abstract The pathogenesis of diphenylhydantoin-induced pure red cell aplasia was investigated in the case of a 32-year-old man who developed pure red cell aplasia while he was under treatment with diphenylhydantoin. The patient's serum IgG purified from serum drawn at the time of diagnosis suppressed normal allogeneic marrow colony-forming (CFU-E) and burst- forming (BFU-E) and autologous blood BFU-E growth in vitro only in the presence of diphenylhydantoin. This IgG-diphenylhydantoin complex had no effect on CFU-GM growth in vitro. Normal IgG or patient's IgG purified from serum drawn after the remission of red cell aplasia had no effect on erythroid colony formation in vitro in the presence of diphenylhydantoin. The IgG-diphenylhydantoin complex exerted no direct cytotoxic effect on normal marrow erythroblasts, CFU-E, and BFU-E, nor did it interfere with the action of erythropoietin on marrow erythroblasts. These studies suggest that diphenylhydantoin-induced red cell aplasia is immunologically mediated through an IgG inhibitor, which requires the presence of the drug to suppress erythroid colony formation in vitro. This inhibitor seems to exert its effect on erythroid progenitors at or beyond the stage of differentiation of CFU- E, but not on erythroblasts.

Epidemiological Profile

IntroductionThe liaison psychiatry (LP) is a feature used by the psychiatrist in order to improve the management of patients with mental suffering and/or mental disorder admitted to general hospital.ObjectivesTo characterize the epidemiological profile of hospitalized patients at the university hospital of the federal university of Sergipe (HU-UFS) submitted to LP.Methodsretrospective and observational study, through analysis of medical records of patients admitted in the wards of clinical medicine and surgery from the HU-UFS, in the period from January to December 2015, submitted to LP. The information collected fed a specific questionnaire developed by the authors, intended for research of socio-demographic data and clinical profile.Resultsthe frequency of request for IP was of 3.5%, with the majority of applications was performed by clinical medicine (71.2%), while the surgical clinic was responsible for 28.8%. The main reason for the request of LP was the presence of depressive symptoms (49.1%). There was a predominance of females (52.5%) and the mean age was 45.9 ± 14.6 years.ConclusionsThe frequency of request for LP was very low, suggesting a difficulty in the early detection of mental disorders by physicians. This finding points to an underreporting of cases, since the prevalence of depressive symptoms in hospitalized patients is over 50% in this institution.Disclosure of interestThe authors have not supplied their declaration of competing interest.
