An evaluation of YouTube video content regarding erectile dysfunction

Purpose: YouTubeTM is one of the most popular social media platforms on the internet, and patients with chronic disease frequently use it to seek treatment options. In this study, we aimed to evaluate the quality of YouTube videos about erectile dysfunction. Materials & methods: The terms “erectile dysfunction treatment”, “erectile dysfunction surgery”, and “cure erectile dysfunction” were entered into the YouTube search bar. A total of 56 videos were included in the study. Videos’ view counts; upload dates; like, dislike, and comment counts; uploader qualifications; length; and content were recorded. Video power index (VPI), Quality Criteria for Consumer Health Information (DISCERN), and Journal of the American Medical Association (JAMA) scores were determined. Results: Thirty-two (57.1%) videos consisted of real images, and 24 (42.9%) contained animated images. Twenty-four (42.9%) videos were uploaded by physicians, and 32 (57.1%) were uploaded by non-physicians. The mean like count of the videos was 5,307 ± 17.618, the mean dislike count was 560.07 ± 1548.07, and the mean comment count was 235 ± 373. The mean VPI value of the videos was calculated as 81.19 ± 21.19, the DISCERN score was 30.5 ± 8.1, and the JAMA score was 1.23 ± 0.55. Overall quality was very poor in 24 (42.9%) of the examined videos, poor in 21 (37.5%), average in 10 (17.9%), and good in one (1.8%). Conclusion: The overall quality of YouTube content on erectile dysfunction was not sufficient to provide reliable information for patients. Physicians should warn patients about the limitations of YouTube and direct them toward more appropriate sources of information

Dizajn maske za lice s UVC-LED zračenjem i njezina djelotvornost protiv uobičajenih klica

During the Covid-19 pandemic, one of the best means of personal protection was using face masks. In this context, the World Health Organization has declared the attempts to produce masks inactivating airborne virus species a welcome initiative. This preliminary study aimed to prove that airborne germs passing through a mask filter cartridge can be destroyed by the rays emitted from UVC LEDs placed in such cartridge. We therefore designed such a face mask and tested the efficiency of UVC LEDs placed in its cartridge against common contaminants, gram-positive Staphylococcus aureus, gram-negative Pseudomonas aeruginosa, and the influenza A/Puerto Rico/8/1934 virus because of its similarity with SARS CoV-2. Eight UVC LEDs with a total power of 75 mW provided sufficient germicidal effect for all three germs. In terms of safety, ozone production released during UVC LED emission was negligible. Our findings are promising, as they show that well-designed UVC-based face masks can be effective against airborne germs, but further research on a greater sample may help us learn more and optimise such face masks.Tijekom pandemije Covida-19 jedan od najboljih oblika osobne zaštite bilo je nošenje maski za lice. U tom je smislu Svjetska zdravstvena organizacija pozdravila pokušaje izrade maski koje ubijaju virusne vrste koje se prenose zrakom. Cilj je ovoga preliminarnog istraživanja bio dokazati da se zrakom nošene klice koje prolaze kroz filtarske uloške mogu uništiti zračenjem UVC ledica smještenih u takve uloške. Stoga smo osmislili masku za lice s tom namjenom i iskušali djelotvornost UVC ledica protiv uobičajenih izvora zaraza: gram-pozitivnoga Staphylococcus aureus, gram-negativnoga Pseudomonas aeruginosa i virusa influence A/Puerto Rico/8/1934 zbog njegove sličnosti s virusom SARS CoV-2. Osam UVC ledica ukupne snage 75 mW iskazale su dovoljan germicidni učinak protiv svih triju klica. U smislu sigurnosti primjene, ozon proizveden tijekom UVC-LED zračenja pokazao se zanemarivim. Naši su rezultati obećavajući jer pokazuju da dobro osmišljene maske za lice s UVC zračenjem mogu biti djelotvorne protiv zrakom nošenih klica, ali će tek daljnja istraživanja na većem uzorku pomoći da doznamo više i usavršimo takve maske za lice

Laparoscopic distal pancreatectomy.

After technological advances and increased experiences, more complicated surgeries including distal pancreatectomy can be easily performed with acceptable oncologic results, and decreased mortality and morbidity. Laparoscopic distal pancreatectomy (LDP) has been shown to have several advantages including less blood loss, less hospital stay, less pain. Several studies comparing open distal pancreatectomy (ODP) and LDP resulted that both techniques have similar results according to pancreas fistulas, oncological results, costs and operation indications. Morbidity is very low in high volume centers, for this reason at least ten cases should be performed for the learning curve. Several authors remarked important technical points in LDP in order to perform safe and acceptable LDP in several studies. Here in this review, we aimed to overview the results of previous studies about LDP and discuss the technical points of LDP

MiR-221 as a Pre- and Postoperative Plasma Biomarker for Larynx Cancer Patients

Objective: In order to identify a plasma microRNA (miRNA) signature of larynx cancer (LCa), we examined miRNAs profile of plasma samples obtained from 30 LCa patients (preoperative and postoperative serum samples) and 30 healthy controls
