RESUMO

BACKGROUND: The present review is part of the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biologic therapies. AIMS: To review, from an infectious diseases perspective, the safety profile of therapies targeting different intracellular signaling pathways and to suggest preventive recommendations. SOURCES: Computer-based Medline searches with MeSH terms pertaining to each agent or therapeutic family. CONTENT: Although BCR-ABL tyrosine kinase inhibitors modestly increase the overall risk of infection, dasatinib has been associated with cytomegalovirus and hepatitis B virus reactivation. BRAF/MEK kinase inhibitors do not significantly affect infection susceptibility. The effect of Bruton tyrosine kinase inhibitors (ibrutinib) among patients with B-cell malignancies is difficult to distinguish from that of previous immunosuppression. However, cases of Pneumocystis jirovecii pneumonia (PCP), invasive fungal infection and progressive multifocal leukoencephalopathy have been occasionally reported. Because phosphatidylinositol-3-kinase inhibitors (idelalisib) may predispose to opportunistic infections, anti-Pneumocystis prophylaxis and prevention strategies for cytomegalovirus are recommended. No increased rates of infection have been observed with venetoclax (antiapoptotic protein Bcl-2 inhibitor). Therapy with Janus kinase inhibitors markedly increases the incidence of infection. Pretreatment screening for chronic hepatitis B virus and latent tuberculosis infection must be performed, and anti-Pneumocystis prophylaxis should be considered for patients with additional risk factors. Cancer patients receiving mTOR inhibitors face an increased incidence of overall infection, especially those with additional risk factors (prior therapies or delayed wound healing). IMPLICATIONS: Specific preventive approaches are warranted in view of the increased risk of infection associated with some of the reviewed agents.

RESUMO

Elderberry (Sambucus spp.) is an emerging horticultural crop used in a variety of foods, wines, and dietary supplements. A better understanding of the elderberry juice complex including its putative health-promoting compounds in relation to genetic and environmental parameters is needed. A multi-location planting of nine elderberry genotypes was established in 2008 at three geographically-diverse sites in Missouri, USA. Fruits were harvested from replicated plots 2009-2011, frozen, and later prepared for laboratory analysis. Polyphenols, organic acids, and sugars were quantified by HPLC and the results evaluated for response to genotype, site, and year. The American genotypes 'Ocoee' and 'Ozark' were consistently higher in chlorogenic acids compared to other genotypes, whereas 'Ocoee' was significantly higher in rutin than 'Ozark'. The European 'Marge' was significantly higher in isoquercitrin and other flavonoids compared to most North American genotypes. Significant differences in polyphenols were also detected among sites and production years. Malic, citric, and tartaric acids varied significantly among genotypes, sites, and years, whereas succinic, shikimic, and fumaric acids generally did not. Levels of lactic, acetic, and propionic acids were negligible in most samples. The American genotype 'Ocoee' was higher in citric and tartaric acids, while lower in malic acid. The sugars glucose and fructose also responded significantly to genotype, site, and year. 'Ocoee', 'Ozark', and 'Marge' perform very well in Missouri horticulturally and appear to have additional potential as cultivars based on their unique juice characteristics.

RESUMO

This study investigated the effects of the administration of long chain omega-3 fatty acids (ω-3 FA) and acetylsalicylic acid (ASA) on inflammation, performance, and fertility in periparturient dairy cows. Five weeks before calving, 26 multiparous dairy cows were randomly assigned to 1 of 3 treatments: ω-3 FA (n = 9; OME), ω-3 FA and ASA (n = 9; OMAS), or palm oil (n = 8; CTR). During the last 3 wk of pregnancy, OME and OMAS groups received daily 12.0 g of fish-derived ω-3 FA, whereas CTR cows received only SFA. In addition, OMAS cows received daily 6.0 mg ASA/kg BW starting at 7 d before calving. Only a few cows had health problems after calving, but those in OMAS were most affected (n = 3 vs. 1 in CTR). Inflammatory status around calving did not improve in OME cows, as confirmed by the patterns of concentration of acute-phase proteins (APP), which were similar to CTR. Compared with CTR and OME, the increase of the positive APP and the decrease of the negative APP (e.g., albumin; P < 0.01) observed in OMAS cows suggested a severe inflammatory status after calving. Compared with OMAS, postcalving energy metabolism was better in OME cows as shown by a lower degree of lipomobilization (smaller BCS drop, greater glucose) and milder ketogenesis (less ß-hydroxybutyrate; P < 0.01). Cows in CTR had optimal fertility indices, whereas OMAS was the worst group. The severe inflammation and the more negative energy balance likely contributed to the poor fertility parameters in those cows. It is known that ASA exerts an inhibitory effect on cyclooxygenases, causing a possible decrease in the synthesis of PGF2α. A decreased concentration of PGF2α is connected with alterations in the physiologic processes related to labor and to uterine motility. Cows in OMAS had a longer pregnancy (P < 0.10 vs.OME) and a greater frequency of retained placenta, which may be attributed to decreased synthesis of PGF2α. The administration of ω-3 FA alone did not delay calving or the expulsion of fetal membranes. In conclusion, long-chain ω-3 FA improved the physiological status of cows, partly through better energy balance. The administration of ASA before calving (even at a low dose) in combination with ω-3 FA did not exert any synergistic positive effect on inflammation and performance.

RESUMO

The choose of the best anaesthesia for carotid surgery is a very debated item: the locoregional techniques probably offer more hemodynamic stability and a direct neurologic monitoring, while general anaesthesia allows the complete control of airways and ventilation and reduces the global stress for the patient. This review analyzes the data of studies that compare general and locoregional anaesthesia. Among the latter, possibly elective techniques, the one described by Winnie combines an optimal analgesic efficacy with the lowest rate of adverse effects. A single bolus of a local anesthetic injected at a C4 level (apex of scalene muscles triangle) guarantees a complete block of the superficial and deep cervical plexuses.

RESUMO

40 patients affected by chronic orthopaedic syndromes, outlasting 6 months, have been treated by transcutaneous electrical stimulation. Has beem employed a new commercial stimulator with these impulse parametres: 50 Hz, 0,2 msec of length, 30 mA. Rubber electrodes on trigger points or myalgic areas were used. Authors obtained the following results: in 14 patients any change, in 10 patients mild improvement but of short effect, in 16 patients a good and long term improvment. skin lesions were not observed during electrical stimulation treatment.
