Internet as a source of medicines information (MI) among frequent internet users

Background: The internet is widely and increasingly used to search for health information. Previous studies have focused mainly on health information on the internet and not specifically on medicines information (MI). Objectives: The aim of this study was to explore the internet as a source of MI compared to other sources of MI; to identify those who use the internet as a source of MI; and to describe patterns of use of the internet as a source of MI. Methods: A cross-sectional design employed a web-based questionnaire posted by patients' and other organizations as well as pharmacies on their websites during six weeks in the beginning of 2014. Logistic regression analysis was used to assess associations of background variables to the use of different MI sources. Results: The most frequently used MI sources among respondents (n = 2489) were package leaflets (90%), pharmacists (83%), physicians (72%), and the internet (68%). According to a multivariate analysis, internet use for MI was associated with female gender, age <65 years, higher education, daily use of the internet, and continuous use of vitamins or herbals. MI was most commonly searched from a Finnish health portal (56%) and websites of pharmacies (41%). Of the respondents, nearly half (43%) used search engines to find information from the internet. The names of the medicinal product, symptom or disease were the most commonly used search terms. Conclusions: Well-educated, young women tend to search MI on the internet. Health care professionals should discuss reliable MI websites and tools that can help patients evaluate the reliability of information.Peer reviewe

The RNA Capping Enzyme Domain in Protein A is Essential for Flock House Virus Replication

The nodavirus flock house virus (FHV) and the alphavirus Semliki Forest virus (SFV) show evolutionarily intriguing similarities in their replication complexes and RNA capping enzymes. In this study, we first established an efficient FHV trans-replication system in mammalian cells, which disjoins protein expression from viral RNA synthesis. Following transfection, FHV replicase protein A was associated with mitochondria, whose outer surface displayed pouch-like invaginations with a ‘neck’ structure opening towards the cytoplasm. In mitochondrial pellets from transfected cells, high-level synthesis of both genomic and subgenomic RNA was detected in vitro and the newly synthesized RNA was of positive polarity. Secondly, we initiated the study of the putative RNA capping enzyme domain in protein A by mutating the conserved amino acids H93, R100, D141, and W215. RNA replication was abolished for all mutants inside cells and in vitro except for W215A, which showed reduced replication. Transfection of capped RNA template did not rescue the replication activity of the mutants. Comparing the efficiency of SFV and FHV trans-replication systems, the FHV system appeared to produce more RNA. Using fluorescent marker proteins, we demonstrated that both systems could replicate in the same cell. This work may facilitate the comparative analysis of FHV and SFV replication.The nodavirus flock house virus (FHV) and the alphavirus Semliki Forest virus (SFV) show evolutionarily intriguing similarities in their replication complexes and RNA capping enzymes.

Cellular state landscape and herpes simplex virus type 1 infection progression are connected

Prediction, prevention and treatment of virus infections require understanding of cell-to-cell variability that leads to heterogenous disease outcomes, but the source of this heterogeneity has yet to be clarified. To study the multimodal response of single human cells to herpes simplex virus type 1 (HSV-1) infection, we mapped high-dimensional viral and cellular state spaces throughout the infection using multiplexed imaging and quantitative single-cell measurements of viral and cellular mRNAs and proteins. Here we show that the high-dimensional cellular state scape can predict heterogenous infections, and cells move through the cellular state landscape according to infection progression. Spatial information reveals that infection changes the cellular state of both infected cells and of their neighbors. The multiplexed imaging of HSV-1-induced cellular modifications links infection progression to changes in signaling responses, transcriptional activity, and processing bodies. Our data show that multiplexed quantification of responses at the single-cell level, across thousands of cells helps predict infections and identify new targets for antivirals

Comparison of two rebound tonometers in healthy horses

Objective: To obtain a reference range for evaluation of intraocular pressure (IOP) in horses using Tonovet Plus (R), to compare the IOP readings obtained with Tonovet (R) and Tonovet Plus (R), and to evaluate the repeatability of readings. Animals studied and Procedures: Intraocular pressure of 30 client-owned horses (60 eyes) with no signs of illness or ocular disease was evaluated using Tonovet (R) and Tonovet Plus (R) rebound tonometers. Horses' mean age was 10.7 (range 6-17) years. Triplicate measurements were performed without using sedatives or local anesthetics, with minimal restraint. Results: Calculated reference intervals (the CLSI robust method) were 14.4-27.2 mmHg for Tonovet (R) and 16.0-26.1 mmHg for Tonovet Plus (R). Mean values (+/- standard deviation, SD [+/- coefficient of variation, CV]) obtained with Tonovet Plus (R)(21.6 +/- 2.45 mmHg [11.3%]) were on average 0.6 mmHg higher than with Tonovet (R)(21.0 +/- 3.14 mmHg [15.0%]), and a negligible statistical difference between the devices was found using the paired sample t test (P = .049). The correlation coefficient for the averaged triplicate measurements was 0.73. The average CV was 4.6% and 4.4% for Tonovet (R) and Tonovet Plus (R), respectively. Conclusions: The repeatability of measurements was very good with both devices. The readings between the two devices differed statistically significantly, but the correlation was considered good and the variation was numerically small, and thus, the difference was considered clinically irrelevant. When monitoring disease process or treatment response in an individual patient, repeated readings are best performed using a similar device to avoid false interpretation of results.Peer reviewe

Pleolipoviridae, a newly proposed family comprising archaeal pleomorphic viruses with single-stranded or double-stranded DNA genomes

Viruses infecting archaea show a variety of virion morphotypes, and they are currently classified into more than ten viral families or corresponding groups. A pleomorphic virus morphotype is very common among haloarchaeal viruses, and to date, several such viruses have been isolated. Here, we propose the classification of eight such viruses and formation of a new family, Pleolipoviridae (from the Greek pleo for more or many and lipos for lipid), containing three genera, Alpha-, Beta-, and Gammapleolipovirus. The proposal is currently under review by the International Committee on Taxonomy of Viruses (ICTV). The members of the proposed family Pleolipoviridae infect halophilic archaea and are nonlytic. They share structural and genomic features and differ from any other classified virus. The virion of pleolipoviruses is composed of a pleomorphic membrane vesicle enclosing the genome. All pleolipoviruses have two major structural protein species, internal membrane and spike proteins. Although the genomes of the pleolipoviruses are single- or double-stranded, linear or circular DNA molecules, they share the same genome organization and gene synteny and show significant similarity at the amino acid level. The canonical features common to all members of the proposed family Pleolipoviridae show that they are closely related and thus form a new viral family.Peer reviewe

Can a long-term continuing education course in patient counselling promote a change in the practice of Finnish community pharmacists?

Access restricted by publisherObjective To assess community pharmacists' perceptions of the impact of a long-term continuing education (CE) course on their patient counselling skills. Methods Three focus groups were conducted with the course participants (n = 17) during the last module of the CE course. Data were analysed using computer software for qualitative analysis. Key findings The focus groups revealed eight preliminary categories that were further categorised into four themes related to the learning process in patient counselling skills. The first theme related to achieving the learning objectives. The second related to personal development, understanding principles of two-way communication, and problems in their implementation in practice. The third theme related to actions taken by the participants in their work place, and the fourth involved the potential conflict between the new skills gained and the traditional communication culture in the participant's pharmacy. Conclusion The CE course provided the community pharmacists with new skills and knowledge in patient counselling and collective in-house training. The findings show that the greatest challenge is to change the communication culture of the pharmacy. To achieve this, it may be necessary for more than one pharmacist from the same pharmacy to participate in the training process at the same time

The majority of type 2 diabetic patients in Finnish primary care are at very high risk of cardiovascular events : A cross-sectional chart review study (STONE HF)

Publisher Copyright: © 2021 The AuthorsAims: To characterize clinical profiles, prevalence of chronic kidney disease (CKD), and treatment patterns in type 2 diabetes (T2D) and heart failure (HF) patients in Finnish primary care. Methods: A total of 1385 patients (1196 with T2D, 50 with HF, and 139 with T2D and HF) in 60 Finnish primary care centers were recruited to this cross-sectional study. Data on demographic and clinical characteristics, laboratory measurements, and medications were collected retrospectively from medical records. T2D patients were classified according to their risk of cardiovascular (CV) events as very high-risk (62%) and other patients (38%). Results: Of the T2D patients, 10% (139/1335) had a diagnosis of HF and 42% (457/1090) had stage 3–5 CKD and/or albuminuria based on laboratory measurement. Of the HF patients, 74% (139/189) had T2D and 78% (114/146) had stage 3–5 CKD and/or albuminuria. Metformin was the most frequently used medication in both very high-risk patients (74%) and other patients (86%). SGLT2 inhibitors and/or GLP-1 analogues were used by 37% of very high-risk patients compared to 42% in other patients. Conclusions: The majority of T2D patients in Finnish primary care are at very high risk of cardiovascular events. However, the implementation of treatments with proven cardioprotective effects in very high-risk patients is currently suboptimal.Peer reviewe

Asthma medication in Finnish Olympic Athletes : No signs of overuse of inhaled β2-agonists.

Introduction: Occurrence of asthma has been reported to be frequent in endurance athletes and especially high in winter sport athletes. Recently, the International Olympic Committee has restricted the use of inhaled [beta]2-agonists and requires documentation for their use. However, epidemiologic data comparing the use of antiasthmatic medication in different sport events are mostly missing. Methods: A cross-sectional questionnaire survey was carried out in 2002. All the athletes (N = 494) financially supported by National Olympic Committee comprised the study group. Of them, 446 (90.3%) filled in a structured questionnaire concerning asthma and allergies, use of medication, characteristics of sport activities, and smoking habits. A representative sample of Finnish young adults (N = 1 504) served as controls. Results: Physician-diagnosed asthma was more common in athletes as compared with controls (13.9% vs 8.4%). Use of any asthma medication was reported by 9.6% of the athletes and by 4.2% of the controls. No difference was observed in the frequency of asthma medication used by winter or summer sport athletes (10.0% vs 9.4%). Inhaled [beta]2-agonists were used by 7.4% and 3.0% of the athletes and controls, respectively. After adjusting for age, sex, and smoking, odds ratio with 95% confidence interval for use of any asthma medication was 0.69 (0.17-2.92) for motor skills demanding events, 1.87 (0.85-4.11) for speed and power sports, 3.00 (1.68-5.37) for team sports, and 4.16 (2.22-7.78) for endurance events as compared with controls. None of the athletes used antiasthmatic medication without physician diagnosis. Conclusions: The frequency of antiasthmatic medication is clearly lower than the occurrence of physician-diagnosed asthma in Finnish Olympic athletes. No evidence of overuse of inhaled [beta]2-agonists is found
