Prevalence and Hypertension Treatment Schedule in Hemodialysis Patients and Renal Transplant Recipients in 2006 and 2014/2016.

BACKGROUND: Hypertension is often recognized in both hemodialysis patients (HDp) and renal transplant recipients (RTRs). The aim of the study was the evaluation of hypertension prevalence and treatment schedule and the achievement of the control of blood pressure according to the Polish Society of Hypertension, European Society of Hypertension, Joint National Committee, and American College of Cardiology/American Heart Association 2017 recommendations. MATERIALS AND METHODS: Observations were done in 2 distinct periods of time: the year 2006 and the years 2014/2016. In 2006, 56 HDp and 316 RTRs were studied. In 2014/2016, 85 HDp and 818 RTRs were studied. The antihypertensive treatment analysis was based on medical records from visits in RTRs and dialyses in HDp. RESULTS: Cardiovascular diseases were diagnosed in 71.4% (2006) and 65.9% (2016) in HDp; 17.7% (2006) and 21.5% (2014) in RTRs. Diabetes was observed in 39.3% (2006) and 34.1% (2016) in HDp; 16.5% (2006) and 23.2% (2014) in RTRs. The target blood pressure control was achieved in 64.3% (2006) and 49.4% (2016) of HDp and in 61.4% (2006) and 45.7% (2014) of RTRs. Three drugs (28.6% and 33.5% in 2006; 30.6% and 29.1% in 2016/2014) or 2 antihypertensive drugs (19.6% and 26.9% in 2006; 22.4% and 27.1% in 2016/2014) were used in HDp and RTRs, respectively. The majority of HDp and RTRs were treated with ß-blockers followed by calcium channel blockers. CONCLUSIONS: The target blood pressure control was achieved in a low percentage of HDp and RTRs. RTRs required multidrug antihypertensive therapy to control blood pressure more often than HDp.

Effect of dietary canthaxanthin and iodine on the production performance and egg quality of laying hens.

In this study, we aimed to evaluate the effect of canthaxanthin (CX) and iodine (I) on the production of laying hens, on counteracting debilitation of the vitelline membrane, and on inhibiting Salmonella growth in eggs stored at 30°C. Three hundred hens were reared in cages. Birds were divided into six feeding groups (10 hens × 5 repetitions) that were administered 0, 3 or 6 ppm of CX and 1 or 10 ppm of I with their diets. Laying rate, egg weights, and feed conversion ratios were controlled. The quality of fresh eggs was assessed in wks 25-26, 48-50 and 62-63 of hens lives. An additional batch of eggs was incubated at the temperature of 30°C, and egg quality changes were monitored on days 3, 6 and 9 of storage. Additionally, eggs collected from four experimental groups of hens whose diets had been iodated with 1 or 10 ppm of I and supplemented with 0 or 6 ppm of CX were infected under laboratory conditions with Salmonella, and incubated for 5 and 10 d. The laying rate, egg weights, and feed conversion ratio were significantly improved. Dietary inclusion of CX contributed to a higher resistance of the vitelline membrane of egg yolks, but only for fresh eggs. Vitelline membrane degradation during egg storage at 30°C was significantly counteracted by dietary inclusion of I at a dose of 10 ppm. The same I dose resulted in the complete inhibition of Salmonella growth until day 10 of incubation, but exclusively for eggs collected from 40-week-old hens. Dietary supplementation with 10 ppm of I was found to impart high level of resistance to the vitelline membrane against the growth of Salmonella in case of eggs stored at 30°C; therefore, I was found to be more beneficial by ensuring longer preservation than that of CX. However, dietary supplementation with CX was found to increase the resistance of vitelline membrane in fresh eggs.

Comparative analysis of structure and strength of vitelline membrane and physical parameters of yolk of ostrich, emu, and greater rhea eggs.

In this study, we analyzed selected morphological traits of eggs, as well as structure, strength, and protein composition of the vitelline membrane (VM) of ostrich, emu, and greater rhea eggs. Ninety eggs (30 for species) were analyzed for the following parameters: egg weight, yolk weight, yolk ratio, and yolk index. In addition, pH value, water activity, consistency index, and flow behavior index were determined. The strength of VM was measured using the TA.HDPlus Texture Analyzer. Micrograph images were taken via a scanning electron microscope. Polyacrylamide gel electrophoresis was conducted under denaturing conditions. Ostrich eggs were characterized by the highest egg and yolk weight compared with those of emu and greater rhea eggs, whereas emu eggs had the highest yolk ratio compared with those of ostrich and greater rhea eggs (P > 0.05). Yolk content differed among the species in terms of water activity; it was found to be higher in emu eggs than in ostrich and greater rhea eggs (P > 0.05). Based on flow curves, yolks of the ratites were classified as pseudoplastic non-Newtonian fluids. The consistency index was significantly higher in yolks of ostrich and emu than that of greater rhea eggs, whereas the VM of yolks of greater rhea eggs was the most resistant (had the highest breaking force = 26.4 g). All species differed significantly regarding the structure of VM, the outer layer (OL) in particular, which was found to constitute fibers of various thicknesses that were differently arranged. Fibers of the OL of the VM of emu, whose fibers were the least differentiated but formed the most compact network, were the most diverse in characterization. An electropherogram of the VM of ostrich revealed 11 primary protein bands: 6 for the OL and 5 for the inner layer (IL), that of emu revealed 9 bands: 5 for the OL and 4 for the IL, and that of greater rhea revealed 10 bands: 6 for the OL and 4 for the IL.

Early and 24 h post-mortem thigh (ilio tibialis) muscle metabolism and meat quality in two genetic types of turkeys and their reciprocal crosses, raised under semi-confined conditions.

1. The experiment was conducted in order to determine the effect of the direction of turkey crossing on quality traits of their thigh muscle. 2. In total, 1358 turkeys of slow- (SG) and fast-growing (FG) lines as well as SF crosses (SG × FG) and FS crosses (FG × SG) were reared with access to free range to 21 weeks of age in the case of males and 15 weeks of age in the case of hens. 3. After slaughter of 15 males and 15 hens from each genetic line, their thigh muscles were examined and the following traits were measured after 5-min, 45-min, 2-h and 24-h post-mortem: temperature, pH, glycogen content (G), lactate content (L) and electrical conductivity (EC). Quality attributes were evaluated based on chemical composition, water holding capacity, cooking loss (%) and colour. 4. The rate of post-mortem changes in temperature, G, L and pH in muscles differed among the 4 lines of turkeys, with the highest metabolic rate determined for muscles of SG turkeys, followed by muscles of SF, FS and FG birds. A more beneficial muscle water holding capacity of both sexes of turkeys and better results of cooking loss in male muscles were found in SG and SF turkeys. The thigh muscles of the crosses were characterised by a higher content of protein and a lower content of fat compared to the muscles of FG turkeys, and in the case of the males also by a higher protein content compared to the muscles of SG birds. 5. Owing to the faster post-mortem metabolism, better water holding capacity, lower cooking loss and fat content at a similar content of protein, the thigh muscles of SF crosses raised in the free range system represent a better quality of meat for consumers compared to the thigh muscles of FS turkeys.

One Hundred Consecutive Liver Transplants Using Institutes Georges Lopez-1 Preservation Solution: Outcomes and Prognostic Factors.

BACKGROUND: There are only 4 prior studies reporting on outcomes of liver transplantation (LT) using Institutes Georges Lopez-1 (IGL-1) preservation solution. Detection of negative predictors of LT using IGL-1 may help finding strategies to protect selected recipients at higher risk of graft failure and death. METHODS: Review of all consecutive adult patients who underwent a first whole-graft LT using IGL-1 at authors' institution from 2013 to 2016. Primary end point was graft failure within the first 90 postoperative days (PODs). Graft losses due to any cause (including all deaths with a functioning graft) were recorded as graft failures. RESULTS: Of all 100 patients included in this study, 37 were women; median age was 58 years (range 18-71). There were 12 graft losses during the first 90 PODs (including 3 cases of primary nonfunction of the liver allograft), and 10 of the 12 graft losses occurred on first 30 PODs. All 12 patients who experienced graft loss (including 1 patient who underwent liver retransplantation) died within the first 90 PODs. Of the total 100 patients, 14 experienced biliary complications. Univariate analysis revealed prolonged warm ischemic time (WIT) as the only predictor of 90-day graft failure (odds ratio = 23.5, confidence interval = 1.29-430.18, P = .03). The cutoff by receiver operating characteristic curve for WIT was 38 minutes (area under the curve = 0.70). Positive predictive value for WIT >38 minutes was 94.3%. CONCLUSIONS: LT using IGL-1 can be performed safely. Similar to prior reports on LT using other preservation solutions, prolonged WIT was associated with adverse outcomes.

Analysis of storage possibility of raw and smoked breast meat of oat-fattened White Koluda® goose based on their quality characteristics.

Raw and smoked (spickgans) fillets of oat-fattened White Koluda® goose were packed in: PET - ethylene terephthalate bags; VSP - 99% vacuum; MAP1 - 80% O2, 20% CO2; MAP2 - 70% N2, 30% O2; MAP3 - 30% O2, 40% N2, 30% CO2, and stored at a temperature of 2°C. On the day of packaging (0 d) and during storage of raw (5, 7, 10 d) and smoked fillets (5, 10, 15 d), the samples were analyzed for weight losses, physicochemical traits, and chemical composition. The study demonstrated the effect of storage time and packaging method on storage yield of raw and smoked fillets. In VSP, the raw fillets were characterized by the lowest amount of leakage, whereas spickgans were characterized by the highest storage yield and weight loss. The analysis of the effect of the modified atmosphere demonstrated the lowest weight loss of raw fillets at, simultaneously, the smallest amount of leakage in MAP1. The spickgans stored in MAP2 showed higher weight, higher yield after storage, and lower storage loss in all terms of analyses compared to MAP1 and MAP3. The greatest cooking loss at simultaneously the lowest pH values was determined for the samples stored in VSP. The WBSF values of raw fillets were decreasing along with storage time, in contrast to WBSF values of spickgans, in which case the value of this parameter increased compared to 0 d. Raw fillets stored in MAP1 and MAP3 were characterized by the most significant increase in the value of L*, by a decrease in the value of a* and an increase in that of b* parameter. Visual assessment of spickgans on 15 d of storage revealed the presence of white sediment on the surface of products, except for the samples stored in VSP. The study demonstrated the effect of storage time on the contents of protein and fat in raw fillets and on the contents of salt and fat in spickgans.

Early and 24 h post-mortem changes in breast muscle quality traits of two turkey genotypes and their reciprocal crosses raised under semi-confined conditions.

An experiment was conducted to determine the effect of reciprocal crossing of turkeys on early and 24 h post-mortem changes in quality traits of their breast muscles. The turkeys of slow-growing (SG) and fast-growing (FG) lines as well as SF (SG × FG) and FS crosses (FG × SG) were reared with access to free range. After slaughter turkey breast muscles were examined in the following terms: 5 min, 45 min, 2 h and 24 h post-mortem, for: temperature, pH, glycogen content (G), lactate content (L) and electrical conductivity (EC). Quality attributes of the breast meat were evaluated based on chemical composition, water holding capacity (WHC), cooking loss (%), shear force (N) and colour (L*, a*, b*). Despite differences in the rate of post-mortem changes, the genotype of turkeys had no significant effect upon many quality traits assessed 24 h post-mortem. Meat of lighter birds (SG and SF) was characterised by a lower fat content but a similar protein content compared to meat of FS and FG turkeys. In addition, meat of males from these groups was darker. Meat from the breast muscles of heavier birds (FS and FG) was harder. Significant negative maternal effects were determined for temperature of meat of both male and female turkeys, for pH2 and EC24 of males as well as for L2, L24 and cooking loss of female meat. Positive heterosis was confirmed only for pH2 of female meat and for G2 of male meat. In summary, the direction of fast- and slow-growing turkey crossing may affect the quality of their meat. However, meat of both types of hybrids reared under semi-confined conditions (with the possibility of using free range) was characterised by appropriate quality parameters.

A case of bronze turkey twins developing from hatching.

A double-yolked egg that was laid by an 11-month-old bronze turkey hen on 2 April, 2013 was reported. The presented case of developing turkey twin embryos is the first ever described case for this species. The egg weighed 125 g and had 74.6 mm in length and 53.0 mm in width. The embryos died between the 23rd and 24th day of incubation. Both twin 1 and twin 2 were fully developed with body weights of: 37.7 g and 40.3 g, respectively. The likely causes of death include inappropriate arrangement of embryos and insufficient gas exchange in the last period of incubation. The embryos were arranged along the long axis of the egg, one underneath the other, and were closely adhering to one another. The twins were different in plumage pigmentation. In twin 1, a spontaneous mutation of plumage pigmentation (B) was observed, whereas twin 2 showed appropriate pigmentation (b+) in respect to parents.

Organic changes in the central nervous system in children on chronic inhaled corticosteroid therapy.

Treatment of asthma, the most common chronic respiratory disease in children, includes long-term inhaled corticosteroids (ICS). The purpose of this study was to analyze the impact of chronic inhaled steroids in children with asthma on changes in the central nervous system (CNS). Eleven children (8-17 years) on at least 4 years inhaled corticosteroid therapy were assessed with magnetic resonance imaging (MRI). All participants underwent a pediatric and neurological examination and spirometry. MRI data were obtained using a 1.5 T scanner with parallel imaging capability. Structural images consisted of axial T1, T2 using turbo spin echo, FLAIR and DWI sequences using typical parameters. Images were assessed in three planes (axial, coronal, and sagittal). Pediatric and neurological examination were normal in all children. In six, the MRI studies revealed small subcortical hyperintense foci. Three had more than five lesions, all of which were smaller than 3 mm. Features of mild supratentorial cortical atrophy were apparent in four. The cerebellum was unremarkable in all children imaged. In conclusion, patients receiving chronic inhaled corticosteroids had small subcortical hyperintense foci and features of mild supratentorial cortical atrophy. These findings suggest that ICS exposure may be associated with the development of organic changes in CNS. Further studies are needed to detail the extent of brain ICS-induced changes in children on chronic inhalative corticosteroid therapy as well as delayed impact of these changes on psychomotor functioning in adulthood.

Effects of hepatitis C virus on cardiovascular risk in infected patients: a comparative study.

The role of hepatitis C virus (HCV) in the pathogenesis of atherosclerosis and cardiovascular events is unclear. The aim of this study was to evaluate the direct effect of HCV on cardiovascular risk and correlate it with pro and anti-inflammatory cytokines in patients with HCV. HCV monoinfected patients, genotype 1, naive, non-obese (BMI<30) and non-diabetics were included and compared to controls (blood donors). Patients with prior diagnosis of cardiovascular diseases, hypertension, chronic renal failure, cancer and chronic use of lipid-lowering drugs or immunosuppressants were excluded. Age, BMI, systolic blood pressure (SBP) and diastolic (DBP), fasting glucose and lipid levels were determined. Serum cytokines (IL-6, IL-10 and TNF-α) and Framingham score were also evaluated. 62 HCV patients, 34 (54.8%) were males and none of them was smoking. The Framingham scores (median and 25th and 75th percentiles) were 12% (6.5-14%), showing an intermediate cardiovascular risk in patients with HCV. There was significant direct correlation between Framingham and total cholesterol (p=0.043) and DBP (p=0.007). HDL-C (p=0.002) was inversely correlated with the Framingham score. HCV patients had higher levels of proinflammatory cytokines (IL-6 and TNF-α) compared to controls (p<0.0001) and the relation of proinflammatory/anti-inflammatory TNF-α/IL10 and IL-6/IL10 were higher in HCV patients (p<0.01). The Framingham score was directly correlated to IL-6 and TNF-α, but differences were not statistically significant. Patients with HCV monoinfected, nonobese, naïve and non diabetic have an intermediate cardiovascular risk, as measured by the Framingham score and high levels of proinflammatory cytokines (IL-6 and TNF).

Effects of a blend of essential oil compounds and benzoic acid on performance of broiler chickens as revealed by a meta-analysis of 4 growth trials in various locations.

A series of growth trials with broiler chicks was conducted in various geographical locations to evaluate the efficacy of a novel eubiotic feed additive (EFA) at various dietary inclusion levels on performance of growing chicks. The EFA product consisted of a blend of essential oil compounds (thymol, eugenol, piperine) with benzoic acid, all belonging to the group of flavoring substances. Although variable in responses, the overall results indicated that 300 mg/kg of this EFA represented an optimum supplementation dose for generation of beneficial performance effects in broilers. A meta-analysis with all data from the 300 mg/kg EFA-supplemented treatments in comparison with the non-supplemented controls revealed that the eubiotic product significantly improved BW on d 21 (+2.0%; P = 0.0021) and on d 42 (+1.4%; P = 0.0151). Furthermore, the birds on the EFA 300 mg/kg treatment expressed a higher average daily gain in the starter phase (d 1-21; +2.1%; P = 0.0023) and over the entire experimental period (d 1-42; +1.5%; P = 0.0154). Feed conversion ratio was more favorable with dietary EFA supplementation (-0.6%; P = 0.0414), when compared with the control birds. Mortality was considered normal and was not affected by the dietary treatment (control = 3.09%; EFA 300 mg/kg = 3.26%). In conclusion, 300 mg/kg of this new eubiotic product demonstrated to effectively improve performance of broiler chicks under various husbandry conditions.
