Show moreBackground: In the era of digital data, the Internet has become the primary source from which individuals draw healthcare information.Objective: The aim of the present study is to determine worldwide public interest in prostate cancer (PCa) treatments, their penetrance and variation, and how they compare over time.Design, setting, and participants: An analysis of worldwide search-engine trends included electronic Google queries from people who searched PCa treatment options from January 2004 to August 2018, worldwide. Join-point regression was performed. Comparisons of annual relative search volume (ARSV), average annual percentage change (AAPC), and temporal patterns were analysed to assess loss or gain of interest.Outcome measurements and statistical analysis: Evaluations were made regarding (1) interest in PCa treatments, (2) comparison of people's interest, and (3) impact of the US Preventive Service Task Force (USPSTF) screening recommendation and National Comprehensive Cancer Network (NCCN) guideline endorsements on Internet searching for PCa treatments.Results and limitations: The mean ARSV for "prostatectomy" was 73% in 2004 and decreased thereafter, reaching a nadir of 36% in 2014 (APC: -7.2%; 95% confidence interval [CI] -7.8, -6.7; p < 0.01). Similarly, decreased interest was recorded for radiation therapy (AAPC: -3.2%; p = 0.1), high-intensity focused ultrasound (AAPC: -2.3%; p = 0.1), hormonal therapy (AAPC: -11.6%; p < 0.01), ablation therapy (AAPC: -4.1%; p < 0.01), cryotherapy (AAPC: -9.9%; p < 0.01), and brachytherapy (AAPC: -8.3%; p < 0.01). A steep interest was found in active surveillance (AS) (AAPC: +14.2%; p < 0.01) and focal therapy (AAPC: +27.5%; p < 0.01). When trends were compared before and after NCCN and USPSTF recommendations, a consistent decrease of all the treatment options was found, while interest in focal therapy and AS showed an augmented mean ARSV (+19.6 and +31.6, respectively).Conclusions: People are increasingly searching the Internet for PCa treatment options. A parallel decrease of interest was found for the nonmonitoring treatments, except for focal therapy, while an important growth of appeal has been recorded for AS. Understanding people inquisitiveness together with their degree of knowledge could be supportive to guiding counselling in the decision-making process and putting effort in certifying patient information.Patient summary: In the era of digital data, patients are increasingly searching the Internet for prostate cancer (PCa) treatment options. To safeguard patients' knowledge, it is mandatory to understand how people seek healthcare information, guaranteeing certified and evidence-based information pertaining to PCa treatments options.

Show moreVentricular tachyarrhythmia (VT) is a major cause of late morbidity and mortality in patients who underwent surgical repair of tetralogy of Fallot. The majority of VTs are monomorphic macro-reentrant VT (MVT) and depend on slow conducting areas of diseased myocardium bordered by unexcitable tissue (anatomical isthmuses). Myocardial fibrosis due to surgical incisions, patch material and valve annuli are typical boundaries of anatomical isthmuses (AI). The conducting myocardium between the pulmonary valve and ventricular septum defect patch is called isthmus 3, and the majority of MVTs originate from this area. During pulmonary valve replacement, there is excellent exposure of isthmus 3. Importantly, after pulmonary valve replacement, the homograft may cover important parts of isthmus 3, which makes percutaneous catheter ablation at a later stage impossible. In all patients who need pulmonary valve replacement late after tetralogy of Fallot repair, preoperative electrophysiology study and electroanatomical mapping can identify patients with inducible MVT or slow conduction carrying high risk of MVT. In these patients, intraoperative cryoablation of isthmus 3 should be performed and bidirectional conduction block across the cryoablation line should be demonstrated by intraoperative differential pacing.
