Abstract

Background. Pacemakers are used to treat syncope in patients with bradyarrhythmia; however, the risk of recurrent syncope has only been investigated in few and smaller studies. Objective. The aim of this study was to investigate the risk of recurrent syncope after pacemaker implantation in patients with bradyarrhythmia and prior syncope. Methods. This retrospective, population-based cohort study included patients with a prior syncope and implantation of a pacemaker using data from the Danish nationwide registers from 1996 to 2017. Cumulative incidence and cox regression was used to estimate the 5-year incidence and the risk of recurrent syncope, respectively. Results. In total, 11,126 patients (median age: 78 years, interquartile range: 69-85, 56% male) were included and the 5-year cumulative incidence of recurrent syncope was 19.6% (95% confidence interval (CI): 18.8-20.3%). Sinus node dysfunction (hazard ratio [HR]: 1.29, 95%CI: 1.17-1.42) and unspecified type of bradyarrhythmia (HR: 1.32, 95%CI: 1.15-1.52) were associated with an increased risk of syncope compared to advanced atrioventricular (AV) block. Male sex (HR: 1.22, 95%CI: 1.22-1.34), cerebrovascular disease (HR: 1.17, 95%CI: 1.05-1.30), and prior number of syncopes were significantly associated with a higher HR of recurrent syncope. Conclusion. Almost one-in-five patients with bradyarrhythmia and prior syncope who had a pacemaker implanted had a recurrent syncope within five years. A higher risk of syncope was observed among patients with sinus node dysfunction and unspecified type of bradyarrhythmia compared to AV block. Male sex, cerebrovascular disease, and prior number of syncopes were associated risk factors of recurrent syncope. [ABSTRACT FROM AUTHOR]

2. Effekten av fysisk aktivitet etter påvist lungekreft før, under og etter behandling

Author

Abstract

t: Lungekreft er den kreftformen som tar flest menneskeliv på verdensbasis. Ved behandling av lungekreft er normale komplikasjoner redusert lungefunksjon, smerter, infeksjon og svekket muskulatur. Hensikten med denne litteraturstudien er å se om fysisk aktivitet kan forbedre fysisk funksjon og om det kan redusere komplikasjon eller forebygge fatigue etter kreftbehandling. Metode: Litteratursøket ble utført 28.02.2023 på PubMed med søkeordene Lung cancer AND Physical activity AND Fatigue after treatment. Studieformatet måtte være “Clinical Trial” eller “Randomized Controlled Trial”. Utfra dette ble 8 studier valgt utfra noen inklusjonskriterier og fellesnevneren for alle studiene var at fysisk aktivitet i form av muskelstyrke, pusteøvelser, mobilitet- eller utholdenhetstrening var inkludert i stor grad av studien. Resultat: 838 deltakere fordelt på 8 studier, 7 studier fokuserte på operabel lungekreft og 1 på inoperabel. Resultater viser at ingen signifikant forskjell mellom studiegruppen (SG) og kontrollgruppen (KG) i fysisk kapasitet, men fysisk aktivitet har positiv effekt i større eller liten grad hos lungekreftpasienter i form av fatigue, selvtillit, komplikasjoner eller økt funksjonskapasiteten og aerob ytelse. Konklusjon: Etter denne litteraturstudien er det grunnlag for å si at fysisk aktivitet har en positiv effekt for lungekreftpasienter før, under og etter behandling. Abstract: Lung cancer is the most fatal form of cancer when it comes to number of deaths at a world basis. Common complications after treatment of lung cancer are pain, infections and reduced lung function and muscle strength. The purpose of this literature study is to see if physical activity can increase physical function, reduce complications like fatigue after the treatment. Methods: The literature search was performed 28th of February 2023 in PubMed with keywords Lung cancer AND Physical activity AND Fatigue after treatment. Study design had to be “Clinical Trial” or “Randomized Controlled Trial”. Eight studies were then selected of the inclusion criteria. The articles that were selected had a great extent of physical activity. Results: 838 participants divided into 8 studies. 7 studies focused on operable lung cancer. Results show no significant difference between the study group (SG) and the control group (KG) in physical capacity, but physical activity showed positive effects in relation to fatigue, self-confidence, complications or increased functional capacity and aerobe endurance. Conclusion: From this literature study we found that physical activity in general has a positive effect on how well a patient feel before, under and after treatment.

Abstract

Background: We studied the scientific yield of the medical PhD program at all Danish Universities.Methods: We undertook a retrospective observational study. Three PhD schools in Denmark were included in order to evaluate the postdoctoral research production over more than 18 years through individual publications accessed by PubMed.Results: A total of 2686 PhD-graduates (1995-2013) with a medical background were included according to registries from all PhD schools in Denmark. They had a median age of 35 years (interquartile range (IQR), 32-38) and 53 % were women at the time of graduation. Scientific activity over time was assessed independently of author-rank and inactivity was measured relative to the date of graduation. Factors associated with inactivity were identified using multivariable logistic regression. 88.6 % of the PhD theses were conducted in internal medicine vs. 11.4 % in surgery. During follow-up (median 6.9 years, IQR 3.0-11.7), PubMed data searches identified that 87 (3.4 %) of the PhD graduates had no publication after they graduated from the PhD program, 40 % had 5 or less, and 90 % had 30 or less. The median number of publications per year after PhD graduation was 1.12 (IQR 0.61-1.99) papers per year. About 2/3 of the graduates became inactive after 1 year and approximately 21 % of the graduates remained active during the whole follow-up. Female gender was associated with inactivity: adjusted odds ratio 1.59 (95 % confidence interval 1.24-2.05).Conclusions: The scientific production of Danish medic PhD-graduates was mainly produced around the time of PhD-graduation. After obtaining the PhD-degree the scientific production declines suggesting that scientific advance fails and resources are not harnessed.
