RESUMEN
Introducción y objetivos: La fibrosis hepática precede a la cirrosis y a la insuficiencia hepática. Las formas subclínicas de fibrosis hepática podrían aumentar el riesgo de eventos cardiovasculares. El objetivo fue describir el valor pronóstico del índice FIB-4 en pacientes con síndrome coronario agudo (SCA) sobre la mortalidad hospitalaria y el pronóstico posterior. Métodos: Estudio retrospectivo de pacientes con SCA en un centro. Los objetivos de análisis fueron la mortalidad en la fase hospitalaria y tras el alta, así como la insuficiencia cardiaca y el sangrado mayor (SM), que se evaluaron tomando como evento competitivo la mortalidad por todas las causas y se presentan los sub-hazard ratios (sHR). Los eventos recurrentes se evaluaron mediante la razón de tasas de incidencia (IRR). Resultados: Se incluyeron a 3.106 pacientes y el 6,66% tenía un índice FIB-4 ≥ 1,3. El análisis multivariado verificó mayor riesgo de mortalidad intrahospitalaria asociado al índice FIB-4 (OR = 1,24; p=0,016) y los pacientes con valores> 2,67 presentaron el doble de riesgo (OR = 2,35; p=0,038). Tras el alta (mediana de seguimiento 1.112 días) el índice FIB-4 no tuvo valor pronóstico de mortalidad pero valores ≥ 1,3 se asociaron a mayor riesgo del primer reingreso (Shr = 1,61; p=0,04) o recurrente (IRR =1,70; p=0,001) de IC. El índice FIB-4 ≥ 1,30 se asoció con mayor riesgo de SM (sHR = 1,62; p=0,030). Conclusiones: La evaluación de la fibrosis hepática por el índice FIB-4 identifica a los pacientes con SCA con mayor riesgo de mortalidad intrahospitalaria pero también con mayor riesgo de IC y SM tras el alta.(AU)
Introduction and objectives: Liver fibrosis is present in nonalcoholic liver disease (NAFLD) and both precede liver failure. Subclinical forms of liver fibrosis might increase the risk of cardiovascular events. The objective of this study was to describe the prognostic value of the FIB-4 index on in-hospital mortality and postdischarge outcomes in patients with acute coronary syndrome (ACS). Methods: Retrospective study including all consecutive patients admitted for ACS between 2009 and 2019. According to the FIB-4 index, patients were categorized as <1.30, 1.30-2.67 or> 2.67. Heart failure (HF) and major bleeding (MB) were assessed taking all-cause mortality as a competing event and subhazard ratios (sHR) are presented. Recurrent events were evaluated by the incidence rate ratio (IRR). Results: We included 3106 patients and 6.66% had a FIB-4 index ≥ 1.3. A multivariate analysis verified a higher risk of in-hospital mortality associated with the FIB-4 index (OR, 1.24; P=.016). Patients with a FIB-4 index> 2.67 had a 2-fold higher in-hospital mortality risk (OR, 2.35; P=.038). After discharge (median follow-up 1112 days), the FIB-4 index had no prognostic value for mortality. In contrast, patients with FIB-4 index ≥ 1.3 had a higher risk of first (sHR, 1.61; P=.04) or recurrent (IRR, 1.70; P=.001) HF readmission. Similarly, FIB-4 index ≥ 1.30 was associated with a higher MB risk (sHR, 1.62; P=.030). Conclusions : The assessment of liver fibrosis by the FIB-4 index identifies ACS patients not only at higher risk of in-hospital mortality but also at higher risk of HF and MB after discharge.(AU)

Artemisia caerulescens L. ssp. densiflora (Viv.) is a wild shrub that grows in the archipelago of La Maddalena, Sardinia, Italy. The antifungal activity of the volatile oil of this sub-species has not been evaluated earlier. This study aimed to identify the main components of the essential oil of A. caerulescens L. ssp. densiflora and to investigate its antifungal activity. Identification of the different components of the essential oil obtained by hydrodistillation from A. caerulescens L. ssp. densiflora was done by both techniques: GC-MS and NMR analyses ((1)H, (13)C, HSQC-NMR). Antifungal activity was evaluated by agar disc diffusion technique against environmental isolates of fungal strains: two yeasts (Rhodotorula spp., Candida spp.), three moulds (Aspergillus spp., Alternaria spp., Fusarium spp.) and a mixture of moulds. GC-MS analysis of the essential oil yielded 42 compounds, out of which, 26 compounds were identified. The main compound was identified as terpinen-4-ol (22%) followed by p-cymene (7.6%) and α-terpineol (3.02%). The significant inhibition spectrum of the essential oil of A. caerulescens L. ssp. densiflora can be considered as an alternative to common disinfectants.

A microbiological environmental investigation was carried out in ten dental clinics in Italy. Microbial contamination of water, air and surfaces was assessed in each clinic during the five working days, for one week per month, for a three-month period. Water and surfaces were sampled before and after clinical activity; air was sampled before, after, and during clinical activity. A wide variation was found in microbial environmental contamination, both within the participating clinics and for the different sampling times. Before clinical activity, microbial water contamination in tap water reached 51,200cfu/mL (colony forming units per milliliter), and that in Dental Unit Water Systems (DUWSs) reached 872,000cfu/mL. After clinical activity, there was a significant decrease in the Total Viable Count (TVC) in tap water and in DUWSs. Pseudomonas aeruginosa was found in 2.38% (7/294) of tap water samples and in 20.06% (59/294) of DUWS samples; Legionella spp. was found in 29.96% (89/297) of tap water samples and 15.82% (47/297) of DUWS samples, with no significant difference between pre- and post-clinical activity. Microbial air contamination was highest during dental treatments, and decreased significantly at the end of the working activity (p<0.05). The microbial buildup on surfaces increased significantly during the working hours. This study provides data for the establishment of standardized sampling methods, and threshold values for contamination monitoring in dentistry. Some very critical situations have been observed which require urgent intervention. Furthermore, the study emphasizes the need for research aimed at defining effective managing strategies for dental clinics.
