BK (BKPyV) and JC (JCPyV) polyomaviruses are widespread in humans. Transmission at an early age and the role of parents in spreading these viruses through the family are incompletely understood. Our aim was to determine the seroprevalence of BKPyV and JCPyV in infants at the age of 1, 2, 6, 12, 24, and 36 months and to assess the frequency of BKPyV and JCPyV seroconversion.

Article Synopsis
  • The study analyzed 226 cases of odontogenic keratocysts (OKCs) over 36 years at a single institute in Southwestern Finland, focusing on their appearance, histopathological features, and recurrence rates.
  • OKCs were found more often in men around the age of 46, typically in the lower jaw, with a recurrence rate of 21%—notably higher in patients with satellite cysts (50%) compared to those without (17%).
  • The findings suggest that regular monitoring is essential for younger patients to catch OKCs early, and the presence of satellite cysts can indicate a greater risk of recurrence.

Introduction: Polyomaviruses have both structural and functional similarities with papillomaviruses. Accordingly, their role in human papillomavirus (HPV) associated malignancies has been studied with conflicting results. Our goal was to disclose any association between BK (BKPyV) and/or JC (JCPyV) polyomavirus serology and HPV data derived from Finnish women (327) in a 6-year prospective follow-up.

BK (BKPyV) and JC (JCPyV) polyomavirus infections are commonly subclinical and known infrequently to cause serious clinical diseases. Longitudinal follow-up studies regarding JCPyV and BKPyV serological outcomes are scanty. We analyzed JCPyV and BKPyV IgG-antibodies in 327 pregnant women and their 132 spouses, enrolled in the longitudinal Finnish Family HPV cohort at Turku University Hospital, Finland.

Next-generation sequencing-based microbiological analysis is a complex way to profile vaginal microbiome samples since each step affects the results gained. Methodologies for sample collection lack golden standards. We compared Puritan DNA/RNA swab (PS) and Copan FLOQ swab (CS) and provided consistent and reliable microbiome profiles analyzed by 16S rRNA gene sequencing.

Article Synopsis
  • The study focused on how often oral epithelial dysplasia (OED) turns into oral squamous cell carcinoma (OSCC) and aimed to find out which histological traits might affect this transformation rate.
  • Over a 29-year period, data from 681 OED patients revealed that 7.5% eventually developed OSCC, with a higher risk observed in more severe dysplasia and lesions located on the tongue.
  • The findings suggest that patients with severe OED, especially on the tongue, should be monitored more closely to allow for earlier detection of potential OSCC.

Objective: Our goal was to study inflammatory bowel disease (IBD) patients' risk of head and neck squamous cell carcinoma (HNSCC), compared to general population.

Materials And Methods: We performed a retrospective nationwide register-based study of Finnish individuals diagnosed with IBD between the years 1995 and 2015. The standardized incidence ratio (SIR) of HNSCC was calculated by comparing the cohort's complementary age-year-sex-person-year incidence to that of the whole Finnish population.

Background: Sialadenoma papilliferum (SP) is a rare minor salivary gland neoplasm that accounts for less than 1% of all salivary gland tumors. The tumor typically affects older people, presenting most commonly as a slow-growing tumor of the hard palate, although other anatomical subsites, comprising the oral cavity and parotid glands, have also been reported.

Case Report: We report a SP occurring in a 90-year-old female.

Background: Type 2 diabetes (T2DM) increases the risk for Alzheimer's disease (AD) but not for AD neuropathology. The association between T2DM and AD is assumed to be mediated through vascular mechanisms. However, insulin resistance (IR), the hallmark of T2DM, has been shown to associate with AD neuropathology and cognitive decline.

Objective: The aim of this study was to examine whether insulin resistance, assessed by HOMA of insulin resistance (HOMA-IR), is an independent predictor of cognitive decline.

Research Design And Methods: The roles of HOMA-IR, fasting insulin and glucose, HbA, and hs-CRP as predictors of cognitive performance and its change were evaluated in the Finnish nationwide, population-based Health 2000 Health Examination Survey and its 11-year follow-up, the Health 2011 study ( = 3,695, mean age at baseline 49.3 years, 55.

Background: No school-based physical activity (PA) interventions among older adolescents have demonstrated long-term effectiveness, and few of them so far have addressed sedentary behaviour (SB). Based on behavioural theories and evidence, we designed a multi-level intervention to increase PA and decrease SB among vocational school students. This study investigates feasibility and acceptability of two main intervention components and research procedures.

Background: As school days among adolescents include long periods of prolonged sitting, teachers are key agents to deliver interventions to reduce youth sedentary behavior. To develop an intervention, acceptability and feasibility of alternative strategies should be tested. We aimed to examine teachers' current use and willingness to use various strategies to decrease student sitting and potential barriers and facilitators of use.

Aims/hypothesis: Type 2 diabetes is an independent risk factor for cognitive decline. Insulin resistance occurring during midlife may increase the risk of cognitive decline later in life. We hypothesised that insulin resistance is associated with poorer cognitive performance and that sex and APOE*E4 might modulate this association.

Background: Common mental disorders (CMD) are prevalent in working populations and have adverse consequences for employee well-being and work ability, even leading to early retirement. Several studies report associations between psychosocial working conditions and CMD. However, there is a lack of longitudinal research within a broad framework of psychosocial working conditions and improvement in CMD.

In this study, a total of 94 lactic acid bacterial (LAB) isolates of porcine small intestinal and fecal origin were screened for their probiotic properties. The aim was to evaluate whether their isolation site and putative species identity play a role in these characteristics and whether either of these can be used as a predictive factor for the probiotic potential of bacterial isolates. The isolates were preliminarily identified by partial 16S rRNA gene sequencing and characterized in vitro for their pH and bile tolerance, adhesion capacity towards porcine enterocytes isolated from five intestinal sites and for antimicrobial activity towards five indicator pathogens.
