Reference-free dual-comb spectroscopy with inbuilt coherence.

We demonstrate a simple system for dual-comb spectroscopy based on two inherently coherent optical frequency combs generated via seeded parametric downconversion. The inbuilt coherence is established by making the two combs share a common comb line. We show that the inbuilt coherence makes it possible to use a simple numerical post-processing procedure to compensate for small drifts of the dual-comb interferogram arrival time and phase.

Immediate Paramedic Tactical Response Unit in a Civilian Emergency Medical Service: The First Year Experience.

Purpose: An immediate paramedic tactical response unit was implemented into a civilian emergency medical services (EMS) system. This was compared with the preexisting traditional tactical EMS support (TEMS). The primary aim of the study was to evaluate the effect on tasking frequencies.

Three out of four disease-modifying anti-rheumatic drug-naïve rheumatoid arthritis patients meet 28-joint Disease Activity Score remission at 12 months: results from the FIN-ERA cohort.

Objective: To assess what proportion of patients with disease-modifying anti-rheumatic drug (DMARD)-naïve early rheumatoid arthritis (ERA) reach 28-joint Disease Activity Score (DAS28) remission over 1 year, and remission variability across clinics in Finland.

Method: Patients with DMARD-naïve newly diagnosed inflammatory arthritis were recruited. The proportion of patients in 28-joint Disease Activity Score with three variables (DAS28-3) remission was compared across sites.

The duration of gastrointestinal and joint symptoms after a large waterborne outbreak of gastroenteritis in Finland in 2007--a questionnaire-based 15-month follow-up study.

An extensive drinking water-associated gastroenteritis outbreak took place in the town of Nokia in Southern Finland in 2007. 53% of the exposed came down with gastroenteritis and 7% had arthritis-like symptoms (joint swelling, redness, warmth or pain in movement) according to a population-based questionnaire study at 8 weeks after the incident. Campylobacter and norovirus were the main pathogens.

Outcome of reactive arthritis after an extensive Finnish waterborne gastroenteritis outbreak: a 1-year prospective follow-up study.

The purpose of the study was to assess the 1-year outcome of definitive reactive arthritis (ReA) after a waterborne outbreak. A cohort of 21 patients (15 females and 6 males, median age 54 years) with ReA related to an extensive waterborne outbreak in Finland was clinically followed-up by rheumatologists with visits at baseline, at 1 month and 3, 6 and 12 months. Although the outcome was in general favourable, 1/3 of the patients had chronic course; 7 (33 %) of the 21 patients needed disease-modifying anti-rheumatic drugs (DMARDs) and even 8 (38 %) of them used glucocorticoids at 12 months.

Joint symptoms after a large waterborne gastroenteritis outbreak--a controlled, population-based questionnaire study.

Objectives: Waterborne outbreaks offer an opportunity to study joint symptoms after a simultaneous exposure. In November 2007, a gastroenteritis outbreak due to faecal contamination of tap water took place in a Finnish town. The purpose of this study was to evaluate the occurrence of joint symptoms after the outbreak.

Reactive arthritis in a population exposed to an extensive waterborne gastroenteritis outbreak after sewage contamination in Pirkanmaa, Finland.

Objectives: To assess the occurrence, clinical picture, and triggering infections of reactive arthritis (ReA) associated with a large waterborne gastroenteritis outbreak.

Methods: After an extensive sewage contamination of the water supply system, an estimated 8453 of the 30 016 inhabitants of the town of Nokia fell ill. General practitioners and occupational physicians were advised to refer any patients with suspicion of new ReA to rheumatological examination including faecal culture, human leucocyte antigen (HLA)-B27 and antibody tests for Campylobacter, Salmonella, and Yersinia.

Biological treatment in rheumatic diseases: results from a longitudinal surveillance: adverse events.

The objective of this study was to assess the long-term safety and tolerability of biologicals in a clinical setting. Data on adverse events (AEs) have been collected over a 5-year period by means of detailed reports sent in to the National Register of Biological Treatment in Finland (ROB-FIN) and validated by information collected by the National Agency for Medicines. Three hundred and eight reports on AEs were filed, concerning a total of 248 patients; this corresponds to 17% of all patients in the ROB-FIN register who started biological treatments.
