    Genomic Influence in the Prevention of Cardiovascular Diseases with a Sterol-Based Treatment
    (Diseases, 2018) San Mauro Martín, Ismael; Blumenfeld Olivares, Javier; Pérez Arruche, Eva; Arce Delgado, Esperanza; Ciudad Cabañas, María José; Garicano Vilar, Elena; Collado Yurrita, Luis Rodolfo
    Raised serum cholesterol concentration is a well-established risk factor in cardiovascular disease. In addition, genetic load may have an indirect influence on cardiovascular risk. Plant-based sterol-supplemented foods are recommended to help reduce the serum low-density lipoprotein cholesterol level. The objective was to analyse the influence of different polymorphisms in hypercholesterolemia patients following a dietary treatment with plant sterols. A randomised double-blind cross-over controlled clinical trial was carried out in 45 people (25 women). Commercial milk, containing 2.24 g of sterols, was ingested daily during a 3-week period, and then the same amount of skim milk, without sterols, was consumed daily during the 3-week placebo phase. Both phases were separated by a washout period of 2 weeks. At the beginning and end of each phase, blood draws were performed. Genes LIPC C-514T and APOA5 C56G are Ser19Trp carriers and greatly benefit from sterol intake in the diet. LIPC C-514T TT homozygous carriers had lower low-density lipoprotein cholesterol (LDL-c) levels than CC homozygote and CT heterozygote carriers after the ingestion of plant sterols (p = 0.001). These two genes also showed statistically significant changes in total cholesterol levels (p = 0.025; p = 0.005), and no significant changes in high-density lipoprotein (HDL) cholesterol levels (p = 0.032; p = 0.003), respectively. No statistically significant differences were observed for other genes. Further studies are needed to establish which genotype combinations would be the most protective against hypercholesterolemia.

    Gene Influence in the Effectiveness of Plant Sterols Treatment in Children: Pilot Interventional Study
    (Nutrients, 2019) San Mauro Martín, Ismael; Garicano Vilar, Elena; Sanz Rojo, Sara; Collado Yurrita, Luis Rodolfo; Pérez Arruche, Eva; Arce Delgado, Esperanza; Blumenfeld Olivares, Javier Andrés
    Cardiovascular disease is linked to high serum low density lipoprotein (LDL)-cholesterol levels. Cardiovascular risk may be indirectly influenced by genetic load. Serum LDL-cholesterol levels may be reduced by the consumption of food enriched with plant sterols (PS). The aim was to test a plant sterol treatment on cholesterol levels according to different genetic polymorphisms. A pilot interventional trial was performed in 26 children (n = 16 girls, n = 10 boys). Seven hundred milliliters/day of commercial skimmed milk with added plant sterols delivering 2.2 g plant sterols were ingested for three weeks. Blood draws were performed at the baseline and end of the study. Significant modifications of non-high density lipoprotein (HDL)-cholesterol (p = 0.010; p = 0.013) and LDL-cholesterol (p = 0.004; p = 0.013) levels appeared in the genes LIPC C-514T and PPAR-α L162V carriers. No statistically significant differences were observed for other genes. LIPC C-514T and PPAR-alpha L162V carriers could benefit from a plant sterol supplement to ameliorate hypercholesterolemia.

    Prevalence of Staphylococcus spp. nasal colonization among doctors of podiatric medicine and associated risk factors in Spain
    (Antimicrobial Resistance & Infection Control, 2018) Benito, Sheila de; Alou Cervera, Luis; Becerro De Bengoa Vallejo, Ricardo; Losa Iglesias, Marta Elena; Gómez-Lus Centelles, María Luisa; Collado Yurrita, Luis Rodolfo; Sevillano Fernández, David
    Background: This study aimed to estimate the prevalence of methicillin-susceptible and -resistant Staphylococcus aureus (MSSA and MRSA) and methicillin-resistant Staphylococcus epidermidis (MRSE) nasopharyngeal carriage among Doctors of Podiatric Medicine (Podiatrists) and to determine the potential risk factors. Methods: A cross-sectional study was carried out in 2016-2017 among 239 podiatrists in Spain. The presence of MSSA, MRSA, and MRSE was determined by microbiological analysis of nasal exudate and antimicrobial susceptibility was determined. Each podiatrist completed a questionnaire. The questionnaire comprised various parameters such as sex, age, podiatry experience duration, underlying diseases, prior antibiotic treatment, hospitalization during the last year, and use of a protective mask, an aspiration system, or gloves. Results: The prevalence of MSSA, MRSA, and MRSE was 23.0%, 1.3%, and 23.8%, respectively. The MSSA prevalence was higher among podiatrists who did not use an aspiration system (32.3%) compared to those who did (19.3%; p = 0.0305), and among podiatrists with respiratory diseases (36.8%) compared to those without (20.8%; p = 0.0272). The MRSE prevalence was higher among men (33.7%) compared to women (8.6%; p = 0.0089), podiatrists aged ≥50 (38.5%) compared to ≤35 (17.8%; p = 0.0101), and podiatrists with ≥15 (39.3%) compared to ≤5 years of podiatry experience (12.5%; p = 0.0015). Among the S. aureus strains, 84.5% were resistant to penicillin, 22.4% to erythromycin, 20.7% to clindamycin, and 12.7% to mupirocin. The MRSE strains were resistant to penicillin (93.0%), erythromycin (78.9%), and mupirocin (73.7%). Conclusions: The prevalence of S. aureus and S. epidermidis nasal carriage is low among Spanish podiatrists compared to other health professionals.

    Effectiveness of surgical hand antisepsis using chlorhexidine digluconate and parachlorometaxylenol hand scrub
    (Medicine (Baltimore) ., 2018) Becerro De Bengoa Vallejo, Ricardo; Sevillano Fernández, David; Alou Cervera, Luis; Martín Aragón, Laura; Losa Iglesias, Marta Elena; Collado Yurrita, Luis Rodolfo; Lopez Lopez, Daniel
    Background: Chlorhexidine and parachlorometaxylenol (PCMX) are antiseptics recommended for surgical hand antisepsis. To our knowledge, PCMX has not been evaluated for bactericidal efficacy "in vivo. Methods: We conducted a randomized, double-blind, controlled crossover trial to compare the bacterial loads on fingertips and fingernails under laboratory conditions after use of antiseptic test products, including chlorhexidine digluconate 4%, PCMX 3%, and a reference solution of propan-1-ol 60% (P-1). We assessed bacterial load after a prewash with soft soap, immediately after application of an antiseptic, and 3 hours after application and wearing of sterile, powder-free gloves. Our procedures followed those specified by European Norm (EN) 12791 for evaluating surgical hand antiseptics and using cotton swab for fingertips and fingernails. Results: Chlorhexidine digluconate 4% and PCMX 3% did not decrease bacterial load on the hands. The bactericidal performances of chlorhexidine digluconate 4% and PCMX 3% did not differ significantly. Chlorhexidine digluconate 4% and PCMX 3% increased bacterial load on the fingertips after participants had worn gloves for 3 hours. Fingernails had greater bacterial loads than skin on the fingertips. Conclusions: Chlorhexidine digluconate 4% and PCMX 3% had similar bactericidal efficacy, but they failed to meet the EN 12791 efficacy standard. Fingernails should be a particular focus of antisepsis in preparation for surgery.The trial was registered at ClinicalTrials.gov (ID: NCT02500758).

    Impact of the biotic and abiotic components of low mineralized natural mineral waters on the growth of pathogenic bacteria of human origin: A key to self-control of spa water quality
    (Journal of Hydrology, 2018) Sevillano Fernández, David; Romero Lastra, Patricia T.; Casado Gómez, Inmaculada; Alou Cervera, Luis; González Hidalgo, Natalia; Collado Yurrita, Luis Rodolfo; Domínguez Gordillo, Adelaida Africa; Arias, Caridad M.; Corvillo Martín, Iluminada; Armijo Castro, Francisco; Romero Martín, Margarita; Maraver Eyzaguirre, Francisco De Paula
    In order to assess the role of the biotic and abiotic components of natural mineral water (NMW) in the spread of allochthonous bacteria in non-thermal spa facilities, we examined the effect of low mineralized NMWs on the growth of several commensal and pathogenic human strains. These NMWs were collected from two Spanish spring spas and had different microbiological characteristics. Microorganisms were exposed to untreated, filtered and autoclaved NMWs at the temperatures of 22 °C and 37 °C for 2 days, mimicking the early stage of starvation. Starvation stress was controlled by the effect identified after incubation in saline. Changes in culturability after exposure were used as a measure of the water’s antibacterial effect. The specific biotic and abiotic effect of NMWs on the suppression of bacterial growth was estimated after excluding the bacterial response to starvation stress, characteristic of this natural oligotrophic environment. The incubation temperature strongly modulated both the consequences of starvation and the impact of the natural biotic and abiotic components of NMWs on the growth of commensal and pathogenic bacteria. A temperature of 22 °C conferred cross-protection of microorganisms to starvation and NMW abiotic stress, whereas a temperature of 37 °C decreased the tolerance to both, and had a negative influence on the abundance and diversity of NMWs microflora. This temperature-dependent behaviour of the allochthonous and autochthonous bacteria explained the different culturability of microorganisms after exposure to untreated NMWs at 22 °C (≈1–2.4 log colony forming units per ml -CFU/ml- mean reduction) and at 37 °C (≈1.8–3.2 log CFU/ml mean reduction). Discarding the effect of starvation, we estimated that the antibacterial effect of NMWs at the temperature of 22 °C was mainly driven by the microecosystem of NMWs, which explained ≥95% of NMW response. In contrast, at optimal temperatures for the growth of commensal and pathogenic microorganisms, ≥60% of the antibacterial response of NMWs was associated with the abiotic components of NMWs. The biotic and abiotic components of NMWs self-preserve the quality of water, preventing the progression of human pathogenic organisms that can occasionally cause water colonization. The influence of the intrinsic components of NMWs on the suppression of microbial growth is strongly modulated by environmental temperature.
