Atrophic gastritis is inversely associated with gastroesophageal reflux disease in a twin register based study.

Background: The association between atrophic gastritis (AG) and symptomatic gastroesophageal reflux disease (GERD) needs to be better assessed.

Objective: We aimed to study this association in a twin setting, controlling for genetic and familial factors, in addition to a range of known covariates.

Methods: We performed a co-twin control study based on the Swedish Twin Registry, including confirmed monozygotic (MZ) and dizygotic (DZ) twins.

Efficacy of Loop-Mediated Isothermal Amplification for Detection as Point-of-Care Testing by Noninvasive Sampling.

For targeted eradication of () to reduce gastric cancer burden, a convenient approach is definitely needed. The purpose of this study was to evaluate the LAMP assay for detection using samples collected by noninvasive and self-sampling methods. The available LAMP assay for detection was appraised and verified using reference and clinically isolated strains.

Human polyomavirus DNA detection in keratoacanthoma and Spitz naevus: no evidence for a causal role.

Keratoacanthomas (KA) and Spitz naevus (SN) are both lesions with unknown aetiology; therefore, the possibility of a viral involvement, more specifically the involvement of human polyomaviruses (HPyV), was investigated. In total, 22 cases of KA and 25 cases of SN were tested for the presence of HPyVs. DNA was extracted and amplified by multiplex PCR and thereafter tested with a multiplex bead-based assay for HPyVs (BKPyV, JCPyV, KIPyV, WUPyV, MCPyV, TSPyV, HPyV6, 7 and 9) and two primate viruses (SV40 and LPyV).

Oral human papillomavirus (HPV) prevalence in youth and cervical HPV prevalence in women attending a youth clinic in Sweden, a follow up-study 2013-2014 after gradual introduction of public HPV vaccination.

During 2009-2011, we reported that the oral and cervical prevalence of human papillomavirus (HPV) was high by international standards at 9.3% and 74%, respectively, in youth aged 15-23 years attending a youth clinic in Stockholm. After gradual introduction of public HPV vaccination during 2007-2012, between 2013 and 2014, when 73% of the women were HPV-vaccinated, but not necessarily before their sexual debut, oral HPV prevalence had dropped to 1.
