Tertiary lymphoid structures in nasopharyngeal carcinoma: A multi-institutional study.

Background: Tertiary lymphoid structures (TLSs) associate with prognosis of many malignancies. However, the clinical significance of TLSs is not well-elucidated in nasopharyngeal carcinoma (NPC) patients.

Material And Methods: In this whole population-based multicenter study, a total of 115 patients treated for NPC were included.

Screen11: validating a screening instrument for voice disorders in accordance with the COSMIN framework.

Purpose: Although numerous patient-reported outcome measures have been developed and validated to quantify the impact of voice problems on different aspects of life, to our knowledge no screening instrument exists that specifically captures voice disorders in a retrospective fashion. The aim of the present study was to examine the psychometric properties and diagnostic validity of a retrospective voice screening method, according to the COSMIN framework for health-related, patient-reported outcome measures. The items in Screen11 have been used to establish the prevalence of voice disorders in both general and occupation-specific populations in the Nordic countries.

Role of Gut Microbiota in Statin-Associated New-Onset Diabetes-A Cross-Sectional and Prospective Analysis of the FINRISK 2002 Cohort.

Background: Dyslipidemia is treated effectively with statins, but treatment has the potential to induce new-onset type-2 diabetes. Gut microbiota may contribute to this outcome variability. We assessed the associations of gut microbiota diversity and composition with statins.

Prognostic Significance of Tumor-associated Stroma in Nasopharyngeal Carcinoma: A Multicenter Study.

Assessment of tumor-associated stroma has shown a reliable prognostic value in recent research. We evaluated the prognostic value of tumor-stroma ratio (TSR) in a large multicenter cohort of nasopharyngeal carcinoma (NPC). We used the conventional hematoxylin and eosin-stained slides of 115 cases of NPC to assess TSR as described in recent guidelines.

Cisplatin overcomes radiotherapy resistance in OCT4-expressing head and neck squamous cell carcinoma.

Objectives: Cisplatin is combined with radiotherapy for advanced head and neck squamous cell carcinoma (HNSCC). While providing a beneficial effect on survival, it also causes side effects and thus is an important target when considering treatment de-escalation. Currently, there are no biomarkers to predict its patient-selective therapeutic utility.

Comprehensive biomarker profiling of hypertension in 36 985 Finnish individuals.

In the largest study to date, we assess the cross-sectional and longitudinal associations between high-abundance serum biomarkers and blood pressure (BP).

Methods: We studied cross-sectional (N = 36 985; age 50.

Finnish Version of the Eating Assessment Tool (F-EAT-10): A Valid and Reliable Patient-reported Outcome Measure for Dysphagia Evaluation.

Our aim was to validate a Finnish version of the Eating Assessment Tool (F-EAT-10) for clinical use and to test its reliability and validity in a multicenter nationwide study. Normative data were acquired from 180 non-dysphagic participants (median age 57.0 years, 62.

Associations of healthy food choices with gut microbiota profiles.

Background: Diet has a major influence on the human gut microbiota, which has been linked to health and disease. However, epidemiological studies on associations of a healthy diet with the microbiota utilizing a whole-diet approach are still scant.

Objectives: To assess associations between healthy food choices and human gut microbiota composition, and to determine the strength of association with functional potential.

Modelling spatial patterns in host-associated microbial communities.

Microbial communities exhibit spatial structure at different scales, due to constant interactions with their environment and dispersal limitation. While this spatial structure is often considered in studies focusing on free-living environmental communities, it has received less attention in the context of host-associated microbial communities or microbiota. The wider adoption of methods accounting for spatial variation in these communities will help to address open questions in basic microbial ecology as well as realize the full potential of microbiome-aided medicine.

Links between gut microbiome composition and fatty liver disease in a large population sample.

Fatty liver disease is the most common liver disease in the world. Its connection with the gut microbiome has been known for at least 80 y, but this association remains mostly unstudied in the general population because of underdiagnosis and small sample sizes. To address this knowledge gap, we studied the link between the Fatty Liver Index (FLI), a well-established proxy for fatty liver disease, and gut microbiome composition in a representative, ethnically homogeneous population sample of 6,269 Finnish participants.

Warming Climate Is Reducing the Diversity of Dominant Microbes in the Largest High Arctic Lake.

Temperatures in the Arctic are expected to increase dramatically over the next century, and transform high latitude watersheds. However, little is known about how microbial communities and their underlying metabolic processes will be affected by these environmental changes in freshwater sedimentary systems. To address this knowledge gap, we analyzed sediments from Lake Hazen, NU Canada.

Swift evolutionary response of microbes to a rise in anthropogenic mercury in the Northern Hemisphere.

Anthropogenic mercury remobilization has considerably increased since the Industrial Revolution in the late 1700s. The Minamata Convention on Mercury is a United Nations treaty (2017) aiming at curbing mercury emissions. Unfortunately, evaluating the effectiveness of such a global treaty is hampered by our inability to determine the lag in aquatic ecosystem responses to a change in atmospheric mercury deposition.

Expression of toll-like receptors in non-endemic nasopharyngeal carcinoma.

Background: Nasopharyngeal carcinoma (NPC) is a malignant disease with an enigmatic etiology. NPC associates with Epstein-Barr virus (EBV) and human papillomaviruses (HPVs), while immunological factors also play a role in carcinogenesis. Toll-like receptors (TLRs) are pattern recognition receptors that participate in the immunological defence against pathogens, but their functions are also linked to cancer.

Epstein-Barr virus and human papillomaviruses as favorable prognostic factors in nasopharyngeal carcinoma: A nationwide study in Finland.

Background: Nasopharyngeal carcinoma (NPC) is related to Epstein-Barr virus (EBV) in endemic areas; however, the role of viruses in nonendemic countries is unclear. Our nationwide study investigated the prevalence and prognostic significance of EBV and human papillomaviruses (HPVs) in Finnish NPC tumors.

Methods: We analyzed samples from 150 patients diagnosed between 1990 and 2009.

Tumor-infiltrating lymphocytes associate with outcome in nonendemic nasopharyngeal carcinoma: a multicenter study.

The prognostic significance of tumor-infiltrating lymphocytes (TILs) has been studied recently in many cancers. For the first time in a nonendemic region, we have evaluated the prognostic value of TILs in a whole population-based nationwide cohort of nasopharyngeal carcinoma (NPC) in Finland. A total of 115 cases from Finnish hospitals were included.

Physicochemical Drivers of Microbial Community Structure in Sediments of Lake Hazen, Nunavut, Canada.

The Arctic is undergoing rapid environmental change, potentially affecting the physicochemical constraints of microbial communities that play a large role in both carbon and nutrient cycling in lacustrine environments. However, the microbial communities in such Arctic environments have seldom been studied, and the drivers of their composition are poorly characterized. To address these gaps, we surveyed the biologically active surface sediments in Lake Hazen, the largest lake by volume north of the Arctic Circle, and a small lake and shoreline pond in its watershed.

Ionic Strength Differentially Affects the Bioavailability of Neutral and Negatively Charged Inorganic Hg Complexes.

Mercury (Hg) bioavailability to bacteria in marine systems is the first step toward its bioamplification in food webs. These systems exhibit high salinity and ionic strength that will both alter Hg speciation and properties of the bacteria cell walls. The role of Hg speciation on Hg bioavailability in marine systems has not been teased apart from that of ionic strength on cell wall properties, however.

Outcome of nasopharyngeal carcinoma in Finland: A nationwide study.

Background: Nasopharyngeal carcinoma (NPC) is uncommon in western countries and data on the outcome and histological presentation are scarce in nonendemic areas. We report here the outcome on all patients with NPC treated in Finland between 1990 and 2009.

Material And Methods: The Finnish Cancer Registry database was used to identify the patients.

Fertilizing with Animal Manure Disseminates Antibiotic Resistance Genes to the Farm Environment.

The dissemination of antibiotic resistance genes to the environment is an important factor causing increased prevalence of resistant pathogens. Manure is an important fertilizer, but it contains diverse resistance genes. Therefore, its application to fields may lead to increased abundance of resistance genes in the environment.

Adenovirus-mediated VEGF-A gene transfer induces bone formation in vivo.

Osteoporosis is a major problem in elderly population. We tested the hypothesis whether vascular endothelial growth factor (VEGF-A) gene transfer is an appropriate way to enhance bone formation and recruitment of osteoblasts in vivo. Adenovirus vectors containing VEGF-A or lacZ cDNAs (1.
