Impact of malnutrition on the quality of life in older patients with advanced heart failure: a cohort study.

OBJECTIVES: The aim of this study was to assess the prevalence of malnutrition, the clinical characteristics associated with malnutrition and the impact of nutritional status on mortality, quality of life, self-care abilities, and activities of daily living in the older patients with advanced heart failure. METHODS: A prospective multicentre cohort study including 260 community-dwelling elderly patients with advanced HF was conducted between June 2017 and December 2019. The study was carried out in 22 primary healthcare centres, three university hospitals, one acute-care hospital, and one geriatric rehabilitation unit in the city of Barcelona (Spain). Nutritional status was assessed at baseline using the Mini Nutritional Assessment questionnaire. Patient-reported outcome measures included quality of life (EQ-5D-3L), self-care behaviour (European Heart Failure Self-care Behaviour Scale) and impact on activities of daily living (Barthel Index). RESULTS: Using the MNA-SF, 126 (48.5%) patients were identified as being at risk of malnutrition and 33 (12.7%) patients as having confirmed malnutrition. Compared to HF patients with normal nutritional status, patients with confirmed malnutrition were significantly older, with a lower BMI, and with reduced haemoglobin levels. During follow-up (median 14.9 months, Interquartile Range; 4.9-26.9), 133 (51.2%) of the included participants died, and mortality was significantly higher among patients identified as having malnutrition (p < 0.001). Better Barthel index and quality of life scores were inversely related to the risk of malnutrition, [Odds Ratio (OR) 0.97 (95% Confidence interval 0.96; 0.98) and OR 0.98 (95% Confidence interval, 0.96; 0.99)], respectively. Higher scores in the European Heart Failure Self-care Behaviour Scale, which implies worse self care, were related to higher malnutrition risk, OR 1.05 (95% Confidence interval, 1.02; 1.09. Adjusted multivariate logistic model found that malnutrition was significantly associated with poor quality of life, and adverse impacts on daily activities and self-care. CONCLUSIONS: In community-dwelling older patients with advanced HF, malnutrition was associated with worse patient reported outcome measures related to poor quality of life, and adverse impacts on self-care and daily activities. Nutritional status must be systematically addressed by primary care nurses and family doctors to improve survival rates in these patients. It would be helpful the incorporation of expert professionals in nutrition in the primary health care centres.

Automated method for the solid phase extraction of tetracyclines in wastewater followed by fluorimetric determination.

This work presents a multisyringe flow injection analysis (MSFIA) system for the automatic extraction and determination of tetracyclines in wastewater samples. The sample was adjusted with Na2EDTA buffer before solid-phase extraction with an Oasis HLB column used for the analyte preconcentration. The europium (Eu3+)-based and citrate-mediated method (using Tris-HCl buffer) was selected for the fluorimetric analysis (λexc/em = 400/612 nm). For fluorescence detection, a low-cost system consisting of an USB 2000 CCD detector and a 3D-printed support that holds a LED light source was used. Under optimized conditions, the proposed method provided low limits of detection (9.4 µg L-1) and quantification (31 µg L-1), and good values for intra-day (<4 %) and inter-day precisions (<6 %). Recoveries of spiked TCs in wastewater samples ranged from 87 to 106 %. The results of this work were in good agreement with the measurements obtained by liquid chromatography coupled to a fluorescence detector.

Morphological and molecular characterization of Trichuris muris (Nematoda: Trichuridae): studies from two commensal rodent species.

In this paper we re-describe Trichuris muris based on morphological data following isolation from two commensal rodent species, Mus musculus from Mexico and Rattus rattus from Argentina. Furthermore, we provide a molecular characterization based on mitochondrial (cytochrome c oxidase subunit 1 mitochondrial gene) and nuclear (internal transcribed spacer 2 region) markers in order to support the taxonomic identification of the studied specimens of T. muris from M. musculus. We distinguished T. muris from 29 species of Trichuris found in American rodents based on morphological and biometrical features, such as the presence of a spicular tube, length of spicule, size of proximal and distal cloacal tube and non-protrusive vulva. We suggest that spicular tube patterns can be used to classify Trichuris species in three groups. Considering that the diagnosis among the species of this genus is mainly based on morphometry, this proposal represents a relevant contribution. We provide molecular studies on two markers, making this the first contribution for T. muris in the Americas. This study makes an important contribution to the integrative taxonomy of cosmopolitan nematode species, and its correct determination from the parasitological study of commensal rodents.

Caffeinated coffee consumption and risk of atrial fibrillation in two Spanish cohorts.

AIMS: The association between caffeinated coffee consumption and atrial fibrillation remains unclear. Recent studies suggest an inverse association only between a moderate caffeinated coffee consumption and atrial fibrillation, but others have reported no association. The aim of our study was to prospectively assess the association between caffeinated coffee consumption and atrial fibrillation in two Spanish cohorts, one of adults from a general population and another of elderly participants at high cardiovascular risk. METHODS AND RESULTS: We included 18,983 and 6479 participants from the 'Seguimiento Universidad de Navarra' (SUN) and 'Prevención con Dieta Mediterránea' (PREDIMED) cohorts, respectively. Participants were classified according to their caffeinated coffee consumption in three groups: ≤3 cups/month, 1-7 cups/week, and >1 cup/day. We identified 97 atrial fibrillation cases after a median follow-up of 10.3 years (interquartile range 6.5-13.5), in the SUN cohort and 250 cases after 4.4 years median follow-up (interquartile range 2.8-5.8) in the PREDIMED study. No significant associations were observed in the SUN cohort although a J-shaped association was suggested. A significant inverse association between the intermediate category of caffeinated coffee consumption (1-7 cups/week) and atrial fibrillation was observed in PREDIMED participants with a multivariable-adjusted hazard ratio = 0.53 (95% confidence interval 0.36-0.79) when compared with participants who did not consume caffeinated coffee or did it only occasionally. No association was found for higher levels of caffeinated coffee consumption (>1 cup per day), hazard ratio = 0.79 (95% confidence interval 0.49-1.28). In the meta-analysis of both PREDIMED and SUN studies, the hazard ratio for intermediate consumption of caffeinated coffee was 0.60 (95% confidence interval 0.44-0.82) without evidence of heterogeneity. Similar findings were found for the association between caffeine intake and atrial fibrillation risk. CONCLUSION: Intermediate levels of caffeinated coffee consumption (1-7 cups/week) were associated with a reduction in atrial fibrillation risk in two prospective Mediterranean cohorts.

Determination of long-chain fatty acids in anaerobic digester supernatant and olive mill wastewater exploiting an in-syringe dispersive liquid-liquid microextraction and derivatization-free GC-MS method.

Long-chain fatty acids (LCFA) are commonly found in lipid-rich wastewaters and are a key factor to monitor the anaerobic digesters. A new simple, fast, precise, and suitable method for routine analysis of LCFA is proposed. The system involves in-syringe-magnetic stirring-assisted dispersive liquid-liquid microextraction (DLLME) prior to gas chromatography-mass spectrometry (GC-MS) without a derivatization process. Calibration curves were prepared in an ethanol solution (R2 ≥ 0.996), which was also useful as disperser solvent. Hexane was chosen as the extraction solvent. Several parameters (pH, ionic strength, extraction solvent volume, stirring time) were optimized in multivariate and univariate studies. Limits of detection (LODs) were found in the range 0.01-0.05 mg L-1 and good precision inter-day (RSDs≤7.9%) and intra-day (RSDs≤4.4%) were obtained. The method was applied to quantify LCFA in supernatants of anaerobic digesters and olive mill wastewaters (OMW). Palmitic, stearic, and oleic acids were the most abundant fatty acid in the analyzed samples and the relative recoveries for all of them were between 81 and 113%.

Automated method for volatile fatty acids determination in anaerobic processes using in-syringe magnetic stirring assisted dispersive liquid-liquid microextraction and gas chromatography with flame ionization detector.

Volatile fatty acids (VFAs) are key parameters to monitor anaerobic digestion processes. Thus, a fast, simple and precise determination of these analytes is necessary for a timely characterization of the biological processes present in municipal solid waste and wastewater treatment plants. In this work, an automated method for the extraction and preconcentration of VFAs, based on dispersive liquid-liquid microextraction with magnetic stirring in syringe, and gas chromatography with flame ionization detector for the separation and detection, is described. The effect of parameters such as the type and volume of extraction solvent, pH, salting out effect and stirring time, was studied using a multivariate and univariate experimental design. Extraction and preconcentration were performed simultaneously using tert-butyl methyl ether (TBME) as the extraction solvent, after stirring 100 s at a constant rate. The detection limits were in the range of 0.1 - 1.3 mg L-1 and a good linearity was observed up to 1000 mg L-1 of the studied VFAs, with a range of R2 between 0.9997 and 0.9999. The intra and interday precision expressed as relative standard deviation (n= 5) varied between 0.7 and 2.4% and between 1.7 and 7.0%, respectively. Subsequently, the developed method was successfully applied to evaluate the presence of VFAs in wastewater samples from anaerobic treatments and an average relative recovery of 102% was obtained.

Molecular diversity of Staphylococcus aureus and the role of milking equipment adherences or biofilm as a source for bulk tank milk contamination.

Staphylococcus aureus is one of the most frequent pathogens causing intramammary infections in dairy herds. Consequently, virulence factors, pathobiology, and epidemiology of Staphylococcus aureus strains have been widely assessed through the years. Nevertheless, not much has been described about the epidemiology of Staph. aureus strains from bulk tank milk (BTM) and adherences on milking equipment (AMES), even when these strains may play a role in the quality of milk that is intended for human consumption. The objective of this study was to assess the strain diversity of 166 Staph. aureus isolates collected from 3 consecutive BTM samples, and from AMES in contact with milk from 23 Chilean dairy farms. Isolates were analyzed and typed using pulsed-field gel electrophoresis. Diversity of strains, both within and among farms, was assessed using Simpson's index of diversity (SID). On farms where Staph. aureus was isolated from both AMES and BTM (n = 8), pulsotypes were further analyzed to evaluate the role of AMES as a potential source of Staph. aureus strains in BTM. Among all Staph. aureus analyzed by pulsed-field gel electrophoresis, a total of 42 pulsotypes (19 main pulsotypes and 23 subtypes) were identified. Among dairy farms, strain diversity was highly heterogeneous (SID = 0.99). Within dairy farms, Staph. aureus strain diversity was variable (SID = 0 to 1), and 18 dairy operations (81.8%) had one pulsotype that was shared between at least 2 successive BTM samples. In those farms where Staph. aureus was isolated in both AMES and BTM (n = 8), 7 (87.5%) showed a clonal distribution of Staph. aureus strains between these 2 types of samples. The overlapping of certain Staph. aureus strains among dairy farms may point out common sources of Staph. aureus among otherwise epidemiologically unrelated farms. Indistinguishable Staph. aureus strains between AMES and BTM across dairy farms suggest that Staph. aureus-containing AMES may represent a source for BTM contamination, thus affecting milk quality. Our study highlights the role of viable Staph. aureus in AMES as a source for BTM contamination on dairy farms, and also describes the overlapping and presence of specific BTM and AMES pulsotypes among farms.

Health-related quality of life in individuals with metabolic syndrome: A cross-sectional study.

INTRODUCTION AND OBJECTIVES: Metabolic syndrome (MetS) is a combination of various cardiovascular risk factors with a major impact on morbidity and premature mortality. However, the impact of MetS on self-reported health-related quality of life (HRQoL) is unknown. This study evaluated the HRQoL in a Spanish adult population aged 55 years and older with MetS. METHOD: A cross-sectional analysis was performed with baseline data from the PREDIMED-Plus multicentre randomized trial. The participants were 6430 men and women aged 55-75 years with overweight/obesity (body mass index ≥27 and ≤40kg/m2) and MetS. The SF-36 questionnaire was used as a tool to measure HRQoL. Scores were calculated on each scale of the SF-36 by gender and age. RESULTS: Participants showed higher scores in the social function (mean 85.9, 95% CI; 85.4-86.4) and emotional role scales (mean 86.8, 95% CI; 86.0-87.5). By contrast, the worst scores were obtained in the aggregated physical dimensions. In addition, men obtained higher scores than women on all scales. Among men, the worst score was obtained in general health (mean 65.6, 95% CI; 65.0-66.2), and among women, in body pain (mean 54.3, 95%CI; 53.4-55.2). A significant decrease was found in the aggregated physical dimensions score among participants 70-75 years old, but an increased one in the aggregated mental dimensions, compared to younger participants. CONCLUSIONS: Our results reflect that the MetS may negatively affect HRQoL in the aggregated physical dimensions, body pain in women, and general health in men. However, this adverse association was absent for the psychological dimensions of HRQoL, which were less affected.

Short communication: Virulence profiles of Staphylococcus aureus isolated from bulk tank milk and adherences on milking equipment on Chilean dairy farms.

Staphylococcus aureus is an important intramammary pathogen for dairy cows that also is remarkably important for public health. Multiple virulence factors can be involved simultaneously during the pathogenesis of a staphylococcal disease, including adhesion proteins, extracellular enzymes, and toxins. The main objective of this study was to assess virulence factors that are associated with cow intramammary infection (IMI) and of human health concern among Staph. aureus isolates obtained from bulk tank milk (BTM) and adherences on milking equipment surfaces. A total of 166 Staph. aureus isolates from 23 dairy farms were characterized according to their virulence profiles. For virulence factors of importance in IMI, the presence of the virulence markers thermonuclease (nuc) and coagulase (coa) and virulence genes such as fibronectin (fnbA) and intercellular adhesion (icaA, icaD) were assessed. For virulence factors of public health concern, presence of antimicrobial resistance (mecA and mecC) and enterotoxin (sea and seb) genes were analyzed. Among all Staph. aureus isolates, 5 virulence profiles were found; the profile nuc(+)coa(+)fnbA(+)icaA(+)icaD(+)mecA(-)mecC(-)sea(-)seb(-) was the most frequently observed (21 out of 23 dairy farms). No differences were found between the virulence profile frequencies of Staph. aureus from BTM and adherences on milking equipment surfaces. The virulence profiles most frequently observed included genes involved in the adherence and biofilm-forming ability of Staph. aureus, which could represent a potential advantage for the bacterium during the early stages of IMI colonization and for persistence on surfaces. Our results indicate a greater frequency of virulence factors of importance for IMI pathogenesis than virulence factors of public health concern, consistent with the dairy origin of isolates. The mecA, mecC, and seb genes were not observed among Staph. aureus isolates analyzed in this study. However, the sea gene was detected in 3 Staph. aureus isolated from BTM, thus posing a potential public health threat. Our results emphasize the importance of understanding the epidemiology and dynamics of Staph. aureus on dairy farms as a tool for the improvement of udder health and milk safety.

Prevalence of peripheral neuropathy associated with chemotherapy in four oncology centers of Colombia. / Prevalencia de neuropatia periferica asociada a quimioterapia en cuatro centros oncologicos de Colombia.

INTRODUCTION: Chemotherapy-induced peripheral neuropathy is a common adverse reaction in a variety of medications frequently used for a great number of cancer treatments. This condition consists of mainly sensory-type symptoms, motor components and autonomic changes. Reported prevalence ranges from 30-68%, after the completion of chemotherapy in non-Latin American people with different populations and socioeconomic levels. AIM: To determine the prevalence of chemotherapy-induced peripheral neuropathy in a Colombian population. PATIENTS AND METHODS: A real-world evidence cross-sectional retrospective study was performed in all patients from oncological clinical centers in Colombia, which received pharmacological therapy for any cancer between January 2015 and December 2016, with taxanes (paclitaxel, docetaxel), alkylators (oxaliplatin), proteasome inhibitors (bortezomib), and epothilone B analogs (ixabepilone). RESULTS: A total of 1,551 patients in four cities were included, and 11,280 doses were applied; predominantly females (n = 1,094; 70.5%), with a mean age of 57 ± 13 years old. Paclitaxel was the most commonly prescribed drug (n = 788; 50.8%). Chemotherapy-induced peripheral neuropathy was developed in 48.9% of paclitaxel, 58.5% of oxaliplatin, 50.5% of docetaxel, 43.7% of bortezomib and 95.2% of ixabepilone patients. Thirty-three patients were treated with two of these medications simultaneously. CONCLUSIONS: Chemotherapy-induced peripheral neuropathy is a frequent adverse reaction to daily cancer therapy in Colombian patients managed with taxanes, alkylators, proteasome inhibitors, and epothilone B analogs. Hence, it is necessary to establish more successful diagnostic methods and incorporate validated scales in the routine evaluation of all patients receiving these medications in our environment.

Mediterranean alcohol-drinking pattern, low to moderate alcohol intake and risk of atrial fibrillation in the PREDIMED study.

BACKGROUND AND AIMS: There is ongoing controversy about the effect of a low to moderate alcohol consumption on atrial fibrillation (AF). Our aim is to assess the association between adherence to a Mediterranean alcohol drinking pattern and AF incidence. METHODS AND RESULTS: A total 6527 out of the 7447 participants in the PREDIMED trial met our inclusion criteria. A validated frequency food questionnaire was used to measure alcohol consumption. Participants were classified as non-drinkers, Mediterranean alcohol drinking pattern (MADP) (10-30 g/d in men and 5-15 g/day in women, preferably red wine consumption with low spirits consumption), low-moderate drinking (<30 g/day men y and < 15 g/day women), and heavy drinking. We performed multivariable Cox regression models to estimate hazard ratios (HR) with 95% confidence intervals (95% CI) of incident AF according to alcohol drinking patterns. After a mean follow up of 4.4 years, 241 new incident AF cases were confirmed. Alcohol consumption was not associated to AF incidence among low-moderate drinkers (HR: 0.96; 95%CI: 0.67-1.37), adherents to MADP (HR: 1.15 95%CI: 0.75-1.75), or heavy drinkers (HR: 0.92; 95%CI: 0.53-1.58), compared with non-drinkers. CONCLUSIONS: In a high cardiovascular risk adult population, a Mediterranean alcohol consumption pattern (low to moderate red wine consumption) was not associated with an increased incidence of AF.

Donation After Cardiac Death in Liver Transplantation: An Additional Source of Organs With Similar Results to Donation After Brain Death.

BACKGROUND: As new sources of organs are needed, liver transplantation using donors after cardiac death (DCD) is progressively increasing, but outcomes with this method are still questioned. This study was accomplished to verify that DCD outcomes are comparable to those seen in donation after brain death (DBD). METHODS: This was a prospective cohort study including 100 liver transplantation performed between 2014 and 2017, divided according to donor type in 75 DBD and 25 DCD. RESULTS: DCD donors were younger (mean age: DCD 56 years, DBD 59 years; P = .009). Mean Modified End-stage Liver Disease (MELD) score was lower for DCD (DCD 16, DBD 19; P < .001). No differences were found regarding ischemia times and development of postreperfusion syndrome or coagulopathy. Primary graft dysfunction was more frequent in DCD (60%, DCD 29.3%; P = .006). Rates of primary graft nonfunction (DCD 0%, DBD 1.3%; P = .562) and acute rejection (DCD 20%, DBD 16.4%; P = .685) were similar. Acute kidney injury occurred more often in DBD (DCD 32%, DBD 12%; P = .051). Length of stay was comparable. Rates of biliary complications (DCD 20%, DBD 26.7%; P = .505) were similar, unlike ischemic cholangiopathy (DCD 12%, DBD 1.3%; P = .018). Retransplantation rates were also similar (DCD 8%, DBD 4%; P = .427) as was survival rate after 3 years (DCD 84%, DBD 86.7%; P = .739). CONCLUSION: DCD represents an additional graft source with results that are encouraging and may be comparable to DBD with a careful donor and recipient selection.

Combined Flush With Histidine-Tryptophan-Ketoglutarate and University of Wisconsin Solutions in Liver Transplantation: Preliminary Results.

INTRODUCTION: Ischemia reperfusion injury (IRI) is the main cause of early allograft dysfunction (EAD) and subsequent primary allograft failure (PAF). OBJECTIVES: The purpose of this study is to compare IRI, EAD, and PAF in liver transplantation in a cohort of patients perfused with histidine-tryptophan-ketoglutarate (HTK) solution and University of Wisconsin (UW) solution versus HTK alone. METHODS: A randomized trial was performed to compare outcomes in liver recipients who underwent transplantation surgery in the University Regional Hospital of Malaga, Spain. Forty patients were randomized to two groups. Primary endpoints included IRI, EAD, PAF, re-intervention, acute cellular rejection, retransplantation, arterial complications, and biliary complications at postoperative day 90. RESULTS: Postoperative glutamic oxaloacetic transaminase (1869.15 ± 1559.75 UI/L vs. 953.15 ± 777.27 UI/L; P = .004) and glutamic pyruvic transaminase (1333.60 ± 1115.49 U/L vs. 721.70 ± 725.02 U/L; P = .023) were significantly higher in patients perfused with HTK alone. A clear tendency was observed in recipients perfused with HTK alone to present moderate to severe IRI (7 patients in the HTK + UW solution group vs. 15 patients in the HTK-alone solution group; P = .06), EAD (0 patients in the HTK + UW solution group vs. 0 patients in the HTK-alone solution group; P = .76), and PAF (3 patients in the HTK + UW solution group vs. 8 patients in the HTK-alone solution group; P = .15). CONCLUSIONS: Initial perfusion with HTK solution followed by UW solution in liver transplantation improves early liver function as compared to perfusion with HTK alone.

Head movement measurement: An alternative method for posturography studies.

The present study evaluated the measurement of head movements as a valid method for postural emotional studies using the comparison of simultaneous recording of center of pressure (COP) sway as criterion. Thirty female students viewed a set of 12 pleasant, 12 unpleasant and 12 neutral pictures from the International Affective Picture System, repeated twice, using a block presentation procedure while standing on a force platform (AMTI AccuSway). Head movements were recorded using a webcam (©KPC139E) located in the ceiling in line with the force platform and a light-emitting diode (LED) placed on the top of the head. Open source software (CvMob 3.1) was used to process the data. High indices of correlation and coherence between head and COP sway were observed. In addition, pleasant pictures, compared with unpleasant pictures, elicited greater body sway in the anterior-posterior axis, suggesting an approach response to appetitive stimuli. Thus, the measurement of head movement can be an alternative or complementary method to recording COP for studying human postural changes.

Up-to-7 Criteria for Hepatocellular Carcinoma Liver Transplantation: A Retrospective Analysis of Experiences.

INTRODUCTION: The expansion of criteria for hepatocellular carcinoma (HCC) liver transplantation should produce satisfactory outcomes in terms of survival and recurrence. OBJECTIVES: To investigate if the up-to-7 criteria are applicable to liver transplantation for HCC. METHODS: A review of all liver transplantations performed at our unit between January 2002 and December 2010 was conducted (645 patients). The 91 patients of the sample who had HCC were divided into 3 groups: in Milan criteria (MC; n = 74), in up-to-7 criteria (UTSC; n = 12), and outside of up-to-7 criteria (OUTSC; n = 5). A descriptive retrospective study was carried out to analyze the characteristics of liver tumors and recipients and to estimate recurrence and survival rates for this population of patients. RESULTS: The characteristics of transplant recipients of the 3 groups were comparable. Statistically significant differences were observed in the number of tumors (1 ± 0.65 for MC, 3 ± 1.05 for UTSC, 6 ± 4.10 for OUTSC; P < .001), largest tumor size (2.47 ± 1.12 cm for MC, 3.78 ± 0.04 cm for UTSC, 4.04 ± 1.73 cm for OUTSC; P < .001), and recurrence (5.4% for MC; 33.3% for UTSC; 20% for OUTSC; P = .008). Survival rates (MC, UTSC, and OUTSC) at 3 and 5 years were 71.6%, 66.7%, and 60%, and 58.1%, 58.3%, and 40%, respectively, whereas tumor-free survival rates were 70.3%, 58.3%, and 60%, and 58.1%, 50%, and 40%, respectively. CONCLUSIONS: Survival in patients with HCC transplanted under up-to-7 criteria is acceptable. However, the expansion of criteria involves an increase in the number of patients included in the waiting list and a higher probability of relapse.
