Lisette J. A. Kogelman, Madeleine Ernst, Katrine Falkenberg, Gianluca Mazzoni, Julie Courraud, Li Peng Lundgren, Susan Svane Laursen, Arieh Cohen, Jes Olesen & Thomas Folkmann Hansen
Abstract Background The cold pressor test (CPT) is a widely used pain provocation test to investigate both pain tolerance and cardiovascular responses. We hypothesize, that performing multi-omic analyses during CPT gives the opportunity to home in on molecular mechanisms involved. Twenty-two females were phenotypically assessed before and after a CPT, and blood samples were taken. RNA-Sequencing, steroid profiling and untargeted metabolomics were performed. Each ‘omic level was analyzed separately at both single-feature and systems-level (principal...

Nielsen, Cecilie Melau, David Greenald, Kristine Juul Hare, Lea Langhoff Thuesen, Eva Dreisler, Kasper Aaboe, Pia Tutein Brenøe, Anna-Maria Andersson, Jakob Albrethsen, Hanne Frederiksen, Ewa Rajpert-De Meyts, Anders Juul, Rod T. Mitchell & Anne Jørgensen
Abstract Background Reduced androgen action during early fetal development has been suggested as the origin of reproductive disorders comprised within the testicular dysgenesis syndrome (TDS). This hypothesis has been supported by studies in rats demonstrating that normal male development and adult reproductive function depend on sufficient androgen exposure during a sensitive fetal period, called the masculinization programming window (MPW). The main aim of this study was therefore to examine the effects of manipulating androgen production...

Deep brain stimulation for neurological disorders: a protocol for a systematic review with meta-analysis and Trial Sequential Analysis of randomised clinical trials

Johanne Juul Petersen, Sophie Juul, Caroline Kamp Jørgensen, Christian Gluud & Janus Christian Jakobsen
Abstract Background Deep brain stimulation has been used since the 1980s for neurological disorders and the USA and Europe have now approved it for Parkinson’s disease, essential tremor, dystonia, and epilepsy. Previous reviews have assessed the effects of deep brain stimulation on different neurological disorders. These reviews all had methodological limitations. Methods This is a protocol for a systematic review based on searches of major medical databases (e.g. MEDLINE, EMBASE, CENTRAL) and clinical trial registries....

Seroprevalence of SARS-CoV-2 antibodies among children and adolescents recruited in a malariometric survey in north-eastern Tanzania July 2021

Eric Lyimo, Cyrielle Fougeroux, Anangisye Malabeja, Joyce Mbwana, Paul M. Hayuma, Edwin Liheluka, Louise Turner, Samwel Gesase, Thomas Lavstsen, John P. A. Lusingu, Daniel T. R. Minja & Christian W. Wang
Abstract Background African countries stand out globally as the region seemingly least affected by the COVID-19 pandemic, caused by the virus SARS-CoV-2. Besides a younger population and potential pre-existing immunity to a SARS-CoV-2-like virus, it has been hypothesized that co-infection or recent history of Plasmodium falciparum malaria may be protective of COVID-19 severity and mortality. The number of COVID-19 cases and deaths, however, may be vastly undercounted. Very little is known about the extent to...

Lusingu & Christentze Schmiegelow
Abstract Background The prevalence of small for gestational age (SGA) may vary depending on the chosen weight-for-gestational-age reference chart. An individual participant data meta-analysis was conducted to assess the implications of using a local reference (STOPPAM) instead of a universal reference (Intergrowth-21) on the association between malaria in pregnancy and SGA. Methods Individual participant data of 6,236 newborns were pooled from seven conveniently identified studies conducted in Tanzania and Malawi from 2003–2018 with data on...

Objectives:Extraosseous plasmacytoma (EOP) is a rare plasma cell neoplasm that tends to convert to plasma cell myeloma (PCM) in about 11% to 35% of cases. It has a predilection for the upper respiratory tract, prototypically affecting the nasal cavity and paranasal sinuses. Contemporary first-line treatment is radiotherapy, with more recent studies showing an added benefit of combining radiation with surgery. In this cohort study, we aimed to examine clinical presentation, treatment, and prognosis for all...

Abstract Background Obsessive-compulsive disorder (OCD) is a debilitating psychiatric disorder which affects up to 3% of children and adolescents. OCD in children and adolescents is generally treated with cognitive behavioural therapy (CBT), which, in more severely affected patients, can be combined with antidepressant medication. The TECTO trial aims to compare the benefits and harms of family-based CBT (FCBT) versus family-based psychoeducation/relaxation training (FPRT) in children and adolescents aged 8 to 17 years. This statistical analysis...

Circular RNAs to predict clinical outcome after cardiac arrest

Francesca M. Stefanizzi, Lu Zhang, Antonio Salgado-Somoza, Josef Dankiewicz, Pascal Stammet, Christian Hassager, Matthew P. Wise, Hans Friberg, Tobias Cronberg, Alexander Hundt, Jesper Kjaergaard, Niklas Nielsen & Yvan Devaux
Abstract Background Cardiac arrest (CA) represents the third leading cause of death worldwide. Among patients resuscitated and admitted to hospital, death and severe neurological sequelae are frequent but difficult to predict. Blood biomarkers offer clinicians the potential to improve prognostication. Previous studies suggest that circulating non-coding RNAs constitute a reservoir of novel biomarkers. Therefore, this study aims to identify circulating circular RNAs (circRNAs) associated with clinical outcome after CA. Results Whole blood samples obtained 48...
