Nonostante i cambiamenti in corso nell'ambito delle pubblicazioni scientifiche (STEM - scienza, tecnologia, ingegneria e medicina), è indubbio che i direttori delle riviste restano i più importanti custodi del processo editoriale. In questo articolo vengono analizzati i motivi per cui i direttori delle riviste devono continuare ad attenersi ai principi editoriali fondamentali e a utilizzare le nuove tecnologie digitali solo per dare forza al contenuto, ma non per sostituirlo nella sua qualità. Per raggiungere questo obiettivo, in un'epoca caratterizzata da controlli ed equilibri, i direttori delle riviste devono essere attentamente sorvegliati e ritenuti responsabili tanto quanto gli autori che essi stessi valutano...

Today, in many European countries, people are looking for wild edible plants to experience new tastes and flavors, by following the new trend of being green and environmentally friendly. Young borage and spinach leaves can be easily confused by inexpert pickers with those of other plants, including poisonous ones, such as Mandragora autumnalis Bertol. (mandrake) or Digitalis purpurea L. (foxglove), common in southern and northern Italy respectively. In the last twenty years, several cases of intoxication by accidental ingestion of mandrake and foxglove have been reported...

A number of rare cardiac diseases can be recognized by electrocardiogram (ECG). This article illustrates the clinical importance of ECG as a key diagnostic tool to detect Wolff-Parkinson-White syndrome and channelopathies, which are frequently diagnosed late after one or more affected family members have become victims of sudden cardiac death. These channelopathies include long QT syndrome, short QT syndrome, Brugada syndrome, and catecholaminergic polymorphic ventricular tachycardia. In addition, typical ECG findings are frequently present in patients with idiopathic ventricular tachycardia, arrhythmogenic right ventricular dysplasia, digitalis intoxication, hyperkalemia, acute cor pulmonale due to pulmonary embolism, as well as severe left ventricular hypertrophy as in hypertrophic cardiomyopathy...

Bacteria on floral tissue can have negative effects by consuming resources and affecting nectar quality, which subsequently could reduce pollinator visitation and plant fitness. Plants however can employ chemical defences to reduce bacteria density. In North American, bee-pollinated Penstemon digitalis , the nectar volatile S -(+)-linalool can influence plant fitness, and terpenes such as linalool are known for their antimicrobial properties suggesting that it may also play a role in plant-microbe interactions...

AIMS: To evaluate the effects of digoxin in patients with the newly described phenotype of heart failure (HF) and mid-range ejection fraction (HFmrEF), attributed to mild left ventricular systolic dysfunction. METHODS AND RESULTS: We carried out a retrospective analysis of the Digitalis Investigation Group (DIG) trial which had 7788 patients available for analysis with a left ventricular ejection fraction (LVEF) ranging between 3% and 85%. We compared the effect of digoxin to placebo in three mutually exclusive groups of patients defined by LVEF category: <40% (HF with reduced LVEF, HFrEF, n = 5874), 40-49% (HFmrEF, n = 1195) and ≥50% (HF with preserved LVEF, HFpEF, n = 719)...

S Serge Barold
This report describes a digitalis-induced regular fascicular ventricular tachycardia characterized by marked QRS alternans a manifestation not usually associated with this arrhythmia. The striking alternation of QRS configuration suggested alternating ventricular activation from either a single focus with two exits in distal branches of the left anterior fascicle or 2 different foci localized in the Purkinje-myocardial network of the left anterior fascicle.

This paper reviews Churchill's illness in Carthage in December 1943. It was characterised by fever that lasted 6 days, left lower lobe pneumonia and two episodes of atrial fibrillation. He was managed in a private villa by Lord Moran, his personal physician, with the assistance of two nurses and the expert advice of colleagues. Sulphadiazine and digitalis leaf were prescribed and Churchill recovered. It is remarkable that, despite the severity of his illness, he continued to direct the affairs of State from his bed...

BACKGROUND AND OBJECTIVE: Previously it was demonstrated that digitalis-like cardiotonic steroid, marinobufagenin (MBG), is implicated in the development of ethanol addiction in rats. We hypothesized that (i) levels of sodium pump ligand, MBG, would be negatively correlated with amount of ethanol consumed by rats, and (ii) that spironolactone would oppose the MBG induced ethanol-seeking behavior and blood pressure in rats. METHODS: Voluntary consumption of 9% alcohol (vs...

Yun-Tao Zhao, Hang Zhou, Yumin Cui
Bidirectional ventricular tachycardia (BVT) is a rare ventricular tachyarrhythmia. It is usually regular, demonstrating a beat-to-beat alternation in the QRS frontal axis that varies between -20° to -30° and +110°. The tachycardia rate is typically between 140 and 180 beats/min and the QRS is relatively narrow, with a duration of 120 to 150 ms. The etiology of published BVT cases is most commonly digitalis toxicity and, rarely, herbal aconitine poisoning, hypokalemic periodic paralysis, catecholaminergic polymorphic ventricular tachycardia (CPVT), myocarditis, and Andersen-Tawil syndrome...

Although the digital transformation is widely viewed as a lever for productivity, it is now also seen, in public occupational health policies, as a factor for the potential increase in occupational risks. This digital transformation can also provide possible solutions enabling the homo digitalis to avoid these risks.

BACKGROUND AND OBJECTIVE: Use of certain medications is recognized as a major and modifiable risk factor for falls. Although the literature on psychotropic drugs is compelling, the literature on cardiovascular drugs as potential fall-risk-increasing drugs is conflicting. The aim of this systematic review and meta-analysis is to provide a comprehensive overview of the associations between cardiovascular medications and fall risk in older adults. METHODS: Design: A systematic review and meta-analysis...

The aim of this study was to investigate the relationship between lameness scoring and clinical findings. The lameness scoring and a gait assessment took place during drying off, the first week after calving and two months after calving in 29 lame and 27 free of lameness cows. In between the farmer scored the lamness. Most of the lameness occurred in the hind limbs and were most frequently caused by dermatitis digitalis, Mortellaro, Limax, and Rusterholz sole ulcer. The mean duration of lameness after treatment was 26 days (median 16 days) and was significantly longer in case of horn lesions than in skin lesions (including interdigital dermatitis)...

WHAT IS KNOWN AND OBJECTIVE: Digoxin is commonly prescribed for heart failure patients with reduced ejection fraction (HFrEF) and patients with atrial fibrillation (AF). Due to digoxin's narrow therapeutic range, monitoring the serum digoxin concentration (SDC) is important. However, the SDC measurement is not widely available. Equations using clinical parameters can be employed to estimate the SDC but have never been studied in the Thai population. Therefore, we conducted this study to evaluate the correlation between the measured SDC and predicted digoxin level using 2 commonly used equations: the Konishi equation and the Koup and Jusko equation...

BACKGROUND: Digoxin has been shown to reduce heart failure hospitalizations with a neutral effect on mortality. It is unknown whether there is heterogeneity of treatment effect for digitalis therapy according to predicted risk of heart failure hospitalization. METHODS AND RESULTS: We conducted a post hoc analysis of the Digitalis Investigator Group (DIG) studies, randomized controlled trials of digoxin vs placebo in participants with heart failure and left ventricular ejection fraction ≤45% (main DIG study, n = 6800) or >45% (ancillary DIG study, n = 988)...

Although endogenous digitalis‑like factor (EDLF) is associated with the development of various physical disorders, the role in preeclampsia remains unclear. This study investigated the effects of EDLF on vascular endothelial cell damage in patients with preeclampsia and the potential mechanisms. From July 2014 to July 2015, 120 singleton pregnancy cases underwent a prenatal examination, inpatient delivery and had normal blood pressure were included in the study, either as patients with severe preeclampsia or the control patients...

Wellens' syndrome represents critical occlusion of the proximal left anterior descending coronary artery. Electrocardiographic changes similar to Wellens' wave are not exceptional to acute coronary occlusion and can also be seen in cardiac and non-cardiac conditions, such as left ventricular hypertrophy, persistent juvenile T wave, bundle branch blocks, cerebral haemorrhage, pulmonary oedema, pulmonary embolism, pheochromocytoma, Takotsubo syndrome, digitalis and cocaine-induced coronary vasospasm. Cocaine-induced pseudo-Wellens' syndrome should be considered as one of the differentials, since cocaine is used frequently by young adults and can cause left anterior descending coronary vasospasm mimicking Wellens' syndrome...

Purpose: Anaplastic thyroid cancer (ATC) is a rare malignancy that accounts for 1-2% of all thyroid cancers. ATC is one of the most aggressive human cancers, with rapid growth, tumor invasion and development of distant metastases. The median survival is only 5 months and the 1-year survival is less than 20%. Moreover, as a result of severe dedifferentiation including the loss of human sodium iodide symporter (hNIS) expression, radioactive iodide (RAI) therapy is ineffective. Recently, we have demonstrated beneficial effects of autophagy activating digitalis-like compounds (DLCs) on redifferentiation and concomitant restoration of iodide uptake in RAI-refractory papillary and follicular thyroid cancer cell lines...

The plant-derived flavonoid, quercetin (QCT), has many biological actions, including cardioprotective actions, resulting from its antioxidant and anti-inflammatory effects. In this study, effects of QCT and its metabolites on the contraction and Ca2+ transients (CaT) of mouse single cardiomyocytes were simultaneously measured and compared with those of isoproterenol and digoxin. Furthermore, cardiac function and plasma concentrations were analyzed after bolus intravenous administration of QCT in mice. QCT and its metabolite, tamarixetin, as well as isoproterenol and digoxin, enhanced the contraction and CaT of cardiomyocytes...
