Obesity effect on newly diagnosed and recurrent post-ablation atrial fibrillation: a systematic review and meta-analysis.

BACKGROUND AND AIMS: The role of overweight and obesity in the development of atrial fibrillation (AF) is well established; however, the differential effect on the occurrence and recurrence of AF remains uncertain. The aim of this review is to compare the effect of underweight and varying degrees of obesity on onset of AF and in recurrent post-ablation AF, and, when possible, in relation to sex. METHODS: A systematic literature search was conducted in PubMed, Embase, and Cochrane Library from inception to January 31, 2023. Studies reporting frequency of newly-diagnosed AF and of recurrent post-ablation AF in different BMI categories, were included. 3400 records were screened and 50 met the inclusion criteria. Standardized data search and abstraction were performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) Statement. Data were extracted from the manuscripts and were analyzed using a random effect model. The outcome was the occurrence of AF in population studies and in patients undergoing ablation. RESULTS: Data from 50 studies were collected, of which 27 for newly-diagnosed AF and 23 for recurrent post-ablation AF, for a total of 15,134,939 patients, of which 15,115,181 in studies on newly-diagnosed AF and 19,758 in studies on recurrent post-ablation AF. Compared to normal weight, the increase in AF was significant (p < 0.01) for overweight, obese, and morbidly obese patients for newly-diagnosed AF, and for obese and morbidly obese patients for recurrent post-ablation AF. Newly-diagnosed AF was more frequent in obese female than obese male patients. CONCLUSION: The effect of increased BMI was greater on the onset of AF, and obese women were more affected than men.

Management of preeclampsia with severe features in a patient with relapsing polychondritis affecting the tracheobronchial tree.

Relapsing polychondritis is a rare disease that affects cartilaginous structures throughout the body. Progressive destruction of the laryngeal structures and the tracheobronchial tree occurs in 50% of patients, potentially leading to loss of patency and collapse of the airway. Respiratory involvement in relapsing polychondritis includes airway stenosis, tracheomalacia and recurrent lung infections due to chronic inflammation caused by the destruction of upper and lower airway cartilage. Pregnancy and preeclampsia can worsen pharyngolaryngeal oedema, while treatment with magnesium sulphate can affect neuromuscular function, exacerbating the degree of airway collapse in the most serious cases of relapsing polychondritis, possibly altering obstetric outcomes. Here, we present the management of a pregnant woman with relapsing polychondritis who presented with features of severe preeclampsia at 29 weeks and 6 days gestation. We believe that this is the first published case of the combination of the two disorders, complicated by acute respiratory failure after treatment with magnesium sulphate.

Staphylococcus aureus adlb gene is associated with high prevalence of intramammary infection in dairy herds of northern Italy: A cross-sectional study.

Staphylococcus aureus is a major mastitis pathogen in dairy cattle worldwide, responsible for substantial economic losses. Environmental factors, milking routine, and good maintenance of milking equipment have been described as important factors to prevent intramammary infections (IMI). Staphylococcus aureus IMI can be widespread within the farm or the infection can be limited to few animals. Several studies have reported that Staph. aureus genotypes differ in their ability to spread within a herd. In particular, Staph. aureus belonging to ribosomal spacer PCR genotype B (GTB)/clonal complex 8 (CC8) is associated with high within-herd prevalence of IMI, whereas other genotypes are generally associated with individual cow disease. The adlb gene seems to be strictly related to Staph. aureus GTB/CC8, and is a potential marker of contagiousness. We investigated Staph. aureus IMI prevalence in 60 herds in northern Italy. In the same farms, we assessed specific indicators linked to milking management (e.g., teat condition score and udder hygiene score) and additional milking risk factors for IMI spread. Ribosomal spacer-PCR and adlb-targeted PCR were performed on 262 Staph. aureus isolates, of which 77 underwent multilocus sequence typing. In most of the herds (90%), a predominant genotype was identified, especially Staph. aureus CC8 (30%). In 19 of 60 herds, the predominant circulating Staph. aureus was adlb-positive and the observed IMI prevalence was relevant. Moreover, the adlb gene was detected only in genotypes of CC8 and CC97. Statistical analysis showed a strong association between the prevalence of Staph. aureus IMI, the specific CCs, and carriage of adlb, with the predominant circulating CC and presence of the gene alone explaining the total variation. Interestingly, the difference in the odds ratio obtained in the models for CC8 and CC97 suggests that it is carriage of the adlb gene, rather than the circulation of these CCs per se, that leads to higher within-herd prevalence of Staph. aureus. In addition, the model showed that environmental and milking management factors had no or minimal effect on Staph. aureus IMI prevalence. In conclusion, the circulation of adlb-positive Staph. aureus strains within a herd has a strong effect on the prevalence of IMI. Thus, adlb can be proposed as a genetic marker of contagiousness for Staph. aureus IMI in cattle. However, further analyses using whole-genome sequencing are required to understand the role of genes other than adlb that may be involved in the mechanisms of contagiousness of Staph. aureus strains associated with high prevalence of IMI.

Identificación de factores que se asocian a alto riesgo de desarrollar diabetes gestacional / Identification of factors associated with a high risk of developing gestational diabetes

Objetivos: Principal. Determinar la prevalencia de los factores de riesgo reconocidos para diabetes gestacional (DG) en nuestra población. Definir el perfil de las pacientes con mayor riesgo de desarrollar DG. Secundario. Analizar la aceptabilidad por parte de las gestantes de las pruebas de cribado. Material y método: Se trata de un estudio observacional ambispectivo en el que se reclutaron 1448 gestantes en un único centro, entre el 1 de diciembre de 2017 y el 31 de julio de 2019. Los criterios de inclusión fueron: no antecedente de diabetes mellitus pregestacional, no antecedente de DG en gestación previa, no antecedentes de cirugía bariátrica, haber realizado cribado para DG en la actual gestación. Resultados: La prevalencia de DG en nuestra población fue del 6,7%. Los factores de riesgo que se asociaron con el desarrollo de DG en nuestra población fueron: edad≥27,5 años (OR: 3,8; IC95%: 2,01-9,16), IMC≥28,5kg/m2 (OR: 2,3; IC95%:1,47-3,59); antecedente de diabetes mellitus en familiares de primer grado (OR: 2,3; IC95%: 1,5-3,66) y la gestación múltiple (OR: 2,8; IC95%: 0,86-6,36). La prevalencia de la DG se incrementó según lo hacía el número de factores de riesgo encontrados en la gestante: desde el 1,4% en las pacientes sin los factores de riesgo hasta el 25.2% con 3 factores de riesgo presentes. El 26,8% de las pacientes calificaron como desagradable la realización del test de ÓSullivan (50g glucosa) y el 65,4% la prueba de sobrecarga oral con 100g de glucosa. Conclusiones: La edad de la gestante≥27,5, el IMC≥28,5kg/m2, el antecedente de diabetes mellitus en familiares de primer y la gestación múltiple son factores que se asocian con alto riesgo de desarrollar DG; estos factores serían suficientes para identificar a la mayoría de las gestantes que desarrollarán DG. Nuestros resultados pueden aplicarse para mejorar los programas de atención prenatal destinados al diagnóstico y tratamiento precoz de la DG.(au)

Objectives: The main objective is to determine the current prevalence of recognised risk factors for gestational diabetes mellitus (GDM) in our region, and to define the profile of patients at higher risk of developing this condition. We also investigate patient acceptability of the screening tests. Material and methods: This is an ambispective study with 1,448 pregnant women recruited between December 2017 and July 2019 from a single centre. Inclusion criteria were no diabetes mellitus prior to the pregnancy, no history of GDM in any previous pregnancy, no history of bariatric surgery before the pregnancy, and GDM screening tests performed. Results: The prevalence of GDM was 6.7%. Risk factors associated with development of GDM were: age≥27.5 years (OR: 3.8; 95% CI: 2.01-9.16); BMI≥28.5kg/m2 (OR: 2.3; 95% CI: 1.47-3.59); history of diabetes mellitus in first-degree relatives (OR: 2.3; 95% CI: 1.5-3.66); and multiple pregnancy (OR: 2.8; 95% CI: 0.86-6.36); Prevalence of GDM increased with the number of risk factors presented by patients: from 1.4% with no risk factor, to 25.2% with 3. The O'Sullivan test (50g glucose) and oral glucose tolerance test (100g glucose) were perceived as “unpleasant” by 26.8% and 65.4% of patients, respectively. Conclusions: Age≥27.5 years, BMI≥28.5kg/m2, history of diabetes mellitus in first-degree relatives, and multiple pregnancy are factors related to an increased risk of GDM; these factors would be enough to identify most pregnant women developing GDM. Our findings may be used to improve programmes aimed at early diagnosis of gestational diabetes and supporting high-risk mothers in antenatal care.(AU)

Mindfulness-based cognitive therapy added to usual care improves eating behaviors in patients with bulimia nervosa and binge eating disorder by decreasing the cognitive load of words related to body shape, weight, and food.

BACKGROUND: This study aimed to investigate the effectiveness of mindfulness-based cognitive therapy (MBCT) as a complementary approach in patients with bulimia nervosa (BN) or binge eating disorder (BED), and to assess how the reduction of the cognitive load of words related to eating disorders (ED) could constitute an intermediate factor explaining its global efficacy. METHODS: Eighty-eight women and men participated in clinical assessments upon inscription, prior to and following 8-week group MBCT. Mindfulness skills were assessed using the five facet mindfulness questionnaire; eating behaviors were assessed using the Three Factor Eating Questionnaire (TFEQ); comorbid pathologies were assessed using the beck depression index and the state-trait anxiety inventory. The cognitive load of words associated with ED was assessed through a modified version of the Stroop color naming task. RESULTS: Mindfulness skills improved significantly (p < .05) after group MBCT. The improvement of TFEQ scores was accompanied by reduced levels of depressive mood and trait anxiety. The positive impact of MBCT on TFEQ score was directly related to an improvement of the performance in the Stroop task. CONCLUSIONS: MBCT represents an interesting complementary therapy for patients with either BN or BED, at least when cognitive and behavioral domains are concerned. Such efficacy seems to be mediated by the reduction of the cognitive load associated with ED stimuli, which offers a possible explanation of how MBCT could reduce binge-eating behaviors. Other studies are needed, in independent centers, to focus more directly on core symptoms and long-term outcome.

Strain wave pathway to semiconductor-to-metal transition revealed by time-resolved X-ray powder diffraction.

One of the main challenges in ultrafast material science is to trigger phase transitions with short pulses of light. Here we show how strain waves, launched by electronic and structural precursor phenomena, determine a coherent macroscopic transformation pathway for the semiconducting-to-metal transition in bistable Ti3O5 nanocrystals. Employing femtosecond powder X-ray diffraction, we measure the lattice deformation in the phase transition as a function of time. We monitor the early intra-cell distortion around the light absorbing metal dimer and the long range deformations governed by acoustic waves propagating from the laser-exposed Ti3O5 surface. We developed a simplified elastic model demonstrating that picosecond switching in nanocrystals happens concomitantly with the propagating acoustic wavefront, several decades faster than thermal processes governed by heat diffusion.

Optimization of a 5-day fixed-time embryo transfer (FTET) protocol in heifers I. Manipulation of circulating progesterone through reutilization of intravaginal progesterone devices during FTET.

The objectives of the present study were to: 1) compare the reproductive efficiency of embryo transfer (ET) recipients after synchronization of estrus or a 5-day synchronization of ovulation protocol for fixed time ET (FTET), and 2) determine the effect of reutilization of intravaginal P4 devices (CIDRs), up to four times, in a 5-day FTET protocol. In Experiment 1, 817 dairy heifers were assigned to one of three groups: PGF + estrus detection, 5-d FTET protocol with new (1.38 g P4) or 2nd use CIDR (previously used once for 5 d). Fresh in vitro produced embryos were transferred 7 ± 1 day after estrus (PGF + estrus) or GnRH (5-day FTET). Utilization rate (transferred/treated) was greater (P < 0.001) in heifers submitted to FTET compared to ET after estrus, however pregnancies per ET (P/ET) were not different (P > 0.10). As a result, pregnancy per treated (P/treated) recipient was greater (P < 0.05) in heifers in the 5-day FTET protocol. In Experiment 2, 40 dairy heifers without a corpus luteum (CL) were randomly allocated into one of four groups using new, 2nd use, 3rd use (previously used twice for 5 d/each), or 4th use (previously used thrice for 5 d/each) CIDRs. Circulating P4 was reduced (P < 0.01) with each reutilization. In Experiment 3, ovarian follicular dynamics were evaluated in 238 dairy heifers submitted to a 5-day protocol with either new, 2nd use, 3rd use or 4th use CIDRs at random stages of the estrous cycle. Prostaglandin F2α (PGF) was administered at CIDR removal and again 24 h later. Ovulation was induced by GnRH treatment 72 h after CIDR removal. Preovulatory follicle diameter increased (P < 0.001) progressively with increasing CIDR reutilization. Ovulation rate did not differ between treatments, however, interval from CIDR removal to ovulation decreased (P < 0.001) in heifers receiving 3rd and 4th use CIDRs compared to new or 2nd use. Finally, in Experiments 4 and 5, 1203 heifers submitted to a 5-day FTET protocol were randomly assigned to receive either a new CIDR, a 3rd use CIDR (Experiment 4) or a 4th use CIDR (Experiment 5). Despite the increase in CL volume on D5 in heifers treated with 3rd use (P = 0.03) or 4th use CIDRs (P < 0.01), there were no differences (P > 0.05) in utilization rate, P/ET, or P/treated. Thus, use of a 5-day FTET synchronization protocol improves reproductive efficiency by increasing recipient utilization, and reutilization of CIDRs up to four times in recipient dairy heifers does not compromise reproductive performance.

Rhinomyiasis by Oestrus ovis in a tourist returning from Corsica.

In the Mediterranean basin, one of the most important agents of myiasis is Oestrus ovis Linnaeus 1758 (Diptera, Oestridae). Herein, we report a rare case of nasal myiasis with a secondary infection complication in a patient from northern Italy who had been visiting Corsica. A healthy, 39-year-old Italian woman spent 2 weeks of vacation in Corsica in June 2018. During her stay, she suddenly felt a foreign body inside her nose, followed by cough, pain, burning at the pharyngeal level, cephalalgia, and nasal congestion with secretions from the nostrils. The clinical examination showed a hyperemic and irritated mucosa and endoscopic examination of the patient's nose and right maxillary sinus revealed three tiny mobile larvae, morphologically and molecular identified as L1 instar larvae of Oestrus ovis. The patient's infestation was probably imported from Corsica, as Mediterranean islands are ideal geographical areas for the development of O. ovis, and the timing of infestation match with the period of O. ovis larviposition. Although rhinomyiasis is rare, it should be considered in people returning from abroad presenting with an acute-onset and foreign body sensation in the nose.

Attention-deficit/hyperactivity disorder symptoms and psychological comorbidity in eating disorder patients.

PURPOSE: There is some evidence that eating disorders (ED) and Attention-deficit/hyperactivity disorder (ADHD) share common clinical features and that ADHD might contribute to the severity of eating disorders. A greater understanding of how the presence of comorbid ADHD may affect the psychopathological framework of eating disorder seems of primary importance. The aim of our study was to evaluate rates of ADHD in three ED subgroups of inpatients: anorexia nervosa restricting type (AN-R), anorexia nervosa binge-eating/purging type (AN-BP) and bulimia nervosa (BN). The secondary aim was the evaluation of the associated psychological characteristics. METHOD: The sample consisted of 73 females inpatients (mean age 28.07 ± 7.30), all with longstanding histories of eating disorder (ED). The presence of a diagnosis of ADHD was evaluated in a clinical interview based on DSM-IV-TR criteria. The following psychometric instruments were used: the eating attitude test (EAT-40), the Bulimic Investigatory Test, Edinburgh (BITE), the Eating Disorder Inventory (EDI-2), the Wender Utah Rating Scale (WURS), the Brown Attention Deficit Disorder Scale (BADDS), the Hamilton scales for Anxiety (HAM-A) and Depression (HAM-D), and the Barrat Impulsivity Scale (BIS-10). RESULTS: Among the three ED subgroups, 13 patients reported comorbidity with ADHD; three in the AN-R subtype, nine in the AN-BP and one in the BN. The remaining 60 patients (n = 34 AN-R; n = 19 AN-BP; n = 7 BN) presented only a diagnosis of ED. The EAT (p = 0.04) and HAM-A (p = 0.02) mean scores were significantly higher in patients with comorbid ADHD. CONCLUSIONS: In our study the comorbidity between ADHD and ED appeared to be frequent, particularly among patients with AN-BP. ED inpatients with higher level of anxiety and more abnormal eating attitudes and bulimic symptoms should be assessed for potentially associated ADHD.

Exploring patient safety culture in preventive medicine settings: an experience from Northern Italy.

INTRODUCTION: Patient safety and quality in healthcare are inseparable. Examining patient safety culture in staff members contributes to further develop quality in healthcare. In Italy there has been some experience in assessing patient safety culture in staff working in hospital. In this pilot study we explored patient safety culture in public health staff working in Italian Local Health Authorities. METHODS: We carried out a descriptive cross sectional study in four Italian territorial Prevention facilities in Northern Italy. We administrated an adapted Italian version of the US Hospital Survey of Patient Safety Culture to all the staff within these facilities. The survey consisted of 10 dimensions based on 33 items, according to the results of a previous psychometric validation. RESULTS: Seventy per cent of the staff responded to the survey (N = 479). Overall, six out of the 10 dimensions exhibited composite scores of positive response frequency for patient safety culture below 50%. While "communication openness" (65%) was the most developed factor, "teamwork across Units" (37%) was the least developed. The work areas with the highest composite scores were Management and the Public Health Laboratory, while in terms of professional categories, Physicians had the highest scores. Patient safety culture in the staff participating in this study was lower than in hospital staff. DISCUSSION: Our descriptive cross sectional study is the first to be carried out in Preventive medicine settings in Italy. It has clearly indicated the need of improvement. Consequently, several interventions with this aim have been implemented.

Water safety in healthcare facilities. The Vieste Charter.

The Study Group on Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health (GISIO-SItI) and the Local Health Authority of Foggia, Apulia, Italy, after the National Convention "Safe water in healthcare facilities" held in Vieste-Pugnochiuso on 27-28 May 2016, present the "Vieste Charter", drawn up in collaboration with experts from the National Institute of Health and the Ministry of Health. This paper considers the risk factors that may affect the water safety in healthcare facilities and reports the current regulatory frameworks governing the management of installations and the quality of the water. The Authors promote a careful analysis of the risks that characterize the health facilities, for the control of which specific actions are recommended in various areas, including water safety plans; approval of treatments; healthcare facilities responsibility, installation and maintenance of facilities; multidisciplinary approach; education and research; regional and national coordination; communication.

Extracellular microRNAs and endothelial hyperglycaemic memory: a therapeutic opportunity?

Type 2 diabetes mellitus (T2DM) is a major cause of cardiovascular (CV) disease. Several large clinical trials have shown that the risk for patients with diabetes of developing CV complications is only partially reduced by early, intensive glycaemic control and lifestyle interventions, and that such complications result from changes in complex, not fully explored networks that contribute to the maintenance of endothelial function. The accumulation of senescent cells and the low-grade, systemic, inflammatory status that accompanies aging (inflammaging) are involved in the development of endothelial dysfunction. Such phenomena are modulated by epigenetic mechanisms, including microRNAs (miRNAs). MiRNAs can modulate virtually all gene transcripts. They can be secreted by living cells and taken up in active form by recipient cells, providing a new communication tool between tissues and organs. MiRNA deregulation has been associated with the development and progression of a number of age-related diseases, including the enduring gene expression changes seen in patients with diabetes. We review recent evidence on miRNA changes in T2DM, focusing on the ability of diabetes-associated miRNAs to modulate endothelial function, inflammaging and cellular senescence. We also discuss the hypothesis that miRNA-containing extracellular vesicles (i.e. exosomes and microvesicles) could be harnessed to restore a 'physiological' signature capable of preventing or delaying the harmful systemic effects of T2DM.

A path analysis of patient dependence and caregiver burden in Alzheimer's disease.

BACKGROUND: The concept of dependence has been proposed as an integrative measure to assess the progression of Alzheimer's disease (AD).This study aimed to investigate the association of patient's dependence level with the caregiver burden within a general theoretical model that includes other well-established determinants. METHODS: Observational and cross-sectional multicenter study. The sample consisted of patients with AD recruited in outpatient consultation offices by a convenience sampling procedure stratified by dementia severity. Cognitive and functional status, behavioral disturbances, dependence level, medical comorbidities, and caregiver burden were assessed by using standardized instruments. A path analysis was used to test the hypothesized relationships between the caregiver burden and its determinants, including the level of dependence. RESULTS: The sample consisted of 306 patients (33.3% mild, 35.9% moderate, 30.7% severe), the mean age was 78.5 years (SD = 7.8), and 66.2% were women. The model fit was acceptable and explained 29% of the caregiver burden variance. Primary stressors were the level of dependence and the distress related to behavioral disturbances. Caregiver's age, gender, and co-residence with the patient were the contextual factors related to caregiver burden. The job status of the caregiver was a significant secondary stressor, functional disability was indirectly associated with caregiver burden via dependence, and frequency of behavioral disturbances was indirectly associated with the caregiver burden via distress. CONCLUSIONS: Dependence was, apart from behavioral disturbances, the most important primary stressor directly related to caregiver burden irrespective of the disease severity.

Long-term use of biosolids as organic fertilizers in agricultural soils: potentially toxic elements occurrence and mobility.

The presence of potentially toxic elements (PTEs) may hinder a more widespread application of biosolids in agriculture. At present, the European Directive 86/278/CEE limit the total concentrations of seven metals (Cu, Cr, Ni, Pb, Zn, Cd and Hg) in agricultural soils and in sewage sludges used as fertilizers but it has not taken into consideration the potential impacts of other emerging micropollutants that may be present in the biosolids as well as their mobility. The aim of this study was to evaluate the accumulation and mobility of 13 elements (including regulated metals and other inorganic species) in agricultural soils repeatedly amended with biosolids for 15 years. Firstly, three digestions programs using different acid mixtures were tested to evaluate the most accurate and efficient method for analysis of soil and sludge. Results demonstrated that sewage sludge application increased concentrations of Pb and Hg in soil, but values did not exceed the quality standard established by legislation. In addition, other elements (As, Co, Sb, Ag, Se and Mn) that at present are not regulated by the Spanish and European directives were identified in the sewage sludge, and significant differences were found between Ag content in soils amended with biosolids in comparison with control soils. This fact can be related to the increasing use of silver nanoparticles in consumer products due to their antibacterial properties. Results from the leaching tests show up that, in general, the mobility degree for both regulated and non-regulated elements in soils amended with biosolids was quite low (<10 %).

Prevalence and spatial distribution of bovine brucellosis in San Luis and La Pampa, Argentina.

BACKGROUND: Bovine brucellosis (BB) is a zoonotic disease caused by Brucella abortus. BB is endemic in Argentina, where vaccination with Brucella abortus strain 19 is compulsory for 3-to-8 month-old heifers. The objectives of this study were to quantify the prevalence of BB and to identify factors associated with its occurrence, along with the spatial distribution of the disease, in the provinces of La Pampa and San Luis. A two-stage random sampling design was used to sample 8,965 cows (3,513 in La Pampa and 5,452 in San Luis) from 451 farms (187 in La Pampa and 264 in San Luis). RESULTS: Cow and herd prevalence were 1.8 % (95 % CI: 1.3-2.2; n = 157) and 19.7 % (95 % CI: 17.0-22.4; n = 89), respectively. Both cow-level and herd-level prevalence in La Pampa (2.4 and 26.0 %, respectively) were significantly higher than in San Luis (1.4 and 15.5 %, respectively). There were not differences between the proportions of reactive cattle compared to that obtained in a survey conducted in 2005. However, herd prevalence in La Pampa was significantly (P < 0.05) higher compared to that study. Disease was found to be spatially clustered in west La Pampa. The lower the bovine density and the calf/cow ratio, the higher odds of belonging to the cluster. CONCLUSIONS: The increase of farm prevalence in the last five years suggests that the disease is spreading and that control measures should be applied in the region. The cluster of infected farms was located in the west region of La Pampa. There, farms have lower animal densities and smaller cow/calf indices compared to the rest of the province. Although western La Pampa has more infected herds, within-farm prevalence was not higher, which suggests that the control program has been relatively successful in controlling the disease at the farm level, and/or that low animal density inherently results in low disease prevalence. Our results provide baseline information on the epidemiology of BB and its potential pattern of transmission in Argentina, which will ultimately help to improve BB control programs in the country.

Red wine intake but not other alcoholic beverages increases total antioxidant capacity and improves pro-inflammatory profile after an oral fat diet in healthy volunteers.

INTRODUCTION: Different alcoholic beverages exert different effects on inflammation and oxidative stress but these results are controversial and scanty in some aspects. We analyze the effect of different alcoholic beverages after a fat-enriched diet on lipid profile, inflammatory factors and oxidative stress in healthy people in a controlled environment. METHODS: We have performed a cross-over design in five different weeks. Sixteen healthy volunteers have received the same oral fat-enriched diet (1486kcal/m(2)) and a daily total amount of 16g/m(2) of alcohol, of different beverages (red wine, vodka, brandy or rum) and equivalent caloric intakes as sugar with water in the control group. We have measured the levels of serum lipids, high sensitivity C-reactive protein (hsCRP), tumor necrosis factor α (TNFα), interleukin 6 (IL-6), soluble phospholipase A2 (sPLA2), lipid peroxidation (LPO) and total antioxidant capacity (TAC). RESULTS: Red wine intake was associated with decreased of mean concentrations of hsCRP, TNFα and IL-6 induced by fat-enriched diet (p<0.05); nevertheless, sPLA2 concentrations were not significantly modified. After a fat-enriched diet added with red wine, TAC increased as compared to the same diet supplemented with rum, brandy, vodka or the control (water with sugar) (p<0.05). CONCLUSIONS: Moderate red wine intake, but not other alcoholic beverages, decreased pro-inflammatory factors and increased total antioxidant capacity despite a fat-enriched diet intake in healthy young volunteers.

[Parenteral administration medicines: recommendations of preparation, administration and stability]. / Medicamentos de administración parenteral: recomendaciones de preparación, administración y estabilidad.

OBJECTIVE: To develop recommendations for the preparation of parenteral drugs (MAP), to assess the transferability of their preparation, from nursing units in the hospital ward to the pharmacy service (SF). METHOD: A table of stabilities of parenteral drugs included in the pharmacotherapeutic guideline was developed using the american and spanish guidelines. Information about MAP was collected (method of preparation, support, maintenance, validity, administration specifications and packaging) by consulting product technical sheets, pharmaceutical industries, literature review and databases. RESULTS: After reviewing 209 drugs, a list of recommendations was developed. According to the data, MAP will be prepared as follows: 89 drugs will be prepared from SF, 62 drugs at nursing units because of its immediate administration requirement and 58 are already packed for its administration by the industry. Of these 62 drugs prepared a nursing units, 14 of them will be prepared in the following doses by the SF. Therefore, 48 drugs will be prepared at nursing units from the 209 parenteral drugs reviewed. CONCLUSIONS: A standardized method of preparation, storage, administration and validity of MAP was established by the SF. The preparation of MAP in the SF extends its shelf life, by considering physicochemical stability, level of risk and product vulnerability to microbiological contamination. The information provided will contribute to a reduction of errors associated with the preparation and administration of MAP.

Objective: To develop recommendations for the preparation of parenteral drugs (MAP), to assess the transferability of their preparation, from nursing units in the hospital ward to the pharmacy service (SF).Method: A table of stabilities of parenteral drugs included in the pharmacotherapeutic guideline was developed using the american and spanish guidelines. Information about MAP was collected (method of preparation, support, maintenance, validity, administration specifications and packaging) by consulting product technical sheets, pharmaceutical industries, literature review and databases. Results: After reviewing 209 drugs, a list of recommendations was developed. According to the data, MAP will be prepared as follows: 89 drugs will be prepared from SF, 62 drugs at nursing units because of its immediate administration requirement and 58 are already packed for its administration by the industry. Of these 62 drugs prepared a nursing units, 14 of them will be prepared in the following doses by the SF. Therefore, 48 drugs will be prepared at nursing units from the 209 parenteral drugs reviewed. Conclusions: A standardized method of preparation, storage, administration and validity of MAP was established by the SF. The preparation of MAP in the SF extends its shelf life, by considering physicochemical stability, level of risk and product vulnerability to microbiological contamination. The information provided will contribute to a reduction of errors associated with the preparation and administration of MAP
