Midline-preserving vs. midline-removing surgery for lumbar spinal stenosis: national registry study based on the Finnish spine registry (FinSpine).

Purpose: Lumbar spinal stenosis (LSS) can be treated surgically by decompressing the affected nervous structures, either by removing or preserving the midline structures. There is no conclusive evidence demonstrating the superiority of either surgical technique in the treatment of LSS. Our purpose was to compare the posterior midline-preserving techniques with midline-removing techniques separately for central stenosis and lateral recess stenosis to evaluate whether either technique leads to superior postoperative results in terms of functional outcome or pain reduction, by using data from the Finnish Spine Registry (FinSpine).

Diagnostic reliability of the FinSpine nationwide spine surgery registry: Comparison between clinical registry diagnoses and blinded imaging assessments.

Introduction: The Finnish national spine surgery registry (FinSpine) collects data on patients, operative procedures, and outcomes.

Research Question: Is the reliability of diagnosis collection for the FinSpine registry across various institutions sufficient?

Methods And Methods: A random sample of 110 spine surgeries performed in Finland since 2017 was selected from the FinSpine registry. Details of the operative procedures, including characteristics of the hospitals, primary and secondary diagnoses, the anatomical level of the spine surgery, and the date of the surgery, were recorded.

Preoperative Predictors of Poor Outcomes Following Lumbar Discectomy. A Study based on the National Finspine Registry.

Study Design: Retrospective cohort study.

Objective: To identify predictors for poor outcome after lumbar discectomy for herniated disc.

Summary Of Background Data: Lumbar discectomy for herniated disc is a common spinal procedure.

Outcome After Anterior Cervical Decompression and Fusion-A Nationwide FinSpine Register Study of Independent Predictors of Outcome at 12 Months After Surgery for Degenerative Cervical Spine.

Study Design: Longitudinal, nationwide register study.

Objective: To identify independent predictors of clinical outcomes at 12 months for patients undergoing primary anterior cervical discectomy and fusion (ACDF) for degenerative cervical spine disease (DCSD).

Summary Of Background Data: ACDF is an established surgical treatment for DCSD.

1-year results of lumbar spinal stenosis surgery in Finland: a national FinSpine register study.

Background And Purpose: While the rates of lumbar spinal stenosis (LSS) surgery have increased continuously internationally, the role of fusion surgery in the treatment of LSS has been under debate. We aimed to assess the outcome of LSS surgery at 1 year postoperatively and to compare decompression surgery with or without fusion based on the Finnish national spine register FinSpine data.

Methods: FinSpine data of surgically treated LSS from 2015 to 2022 was included.

Incidence of juvenile idiopathic arthritis in Finland, 2000-2020.

Objective: Previous epidemiological data of JIA in Finland are from the turn of the millennium. We aimed to determine the recent annual incidence of JIA in several consecutive years in Finland and to explore the differences in incidence between sexes, age groups and regions.

Methods: We analysed all children <16 years of age who met the ILAR classification criteria for JIA.

Intense symptoms of pain are associated with poor sleep, fibromyalgia, depression and sleep apnea in patients with rheumatoid arthritis and psoriatic arthritis. A register-based study.

Objectives: To study whether poor sleep and comorbidities are associated with high symptom levels of patient-reported outcomes (PROs) pain, patient global assessment and fatigue in patients with rheumatoid arthritis (RA) and psoriatic arthritis (PsA), in a nation-wide cross-sectional setting.

Methods: Clinical data were extracted from The Finnish Rheumatology Quality Register between 1.2021 and 9.

Similar levels of disease activity and remission rates in patients with psoriatic arthritis and rheumatoid arthritis-results from the Finnish quality register.

Objectives: To compare the current disease activity and remission rates, and their regional variation in patients with psoriatic arthritis (PsA) and rheumatoid arthritis (RA) in Finland.

Methods: Data of patients' most recent visit in 1/2020-9/2021 were extracted from the Finnish Rheumatology Quality Register. Measures for disease activity and remission included joint counts, DAS28, cDAPSA, CDAI, the Boolean definition, and physician assessment.

Initial presentation of early rheumatoid arthritis.

Objectives: To study the joint distribution and clinical picture of rheumatoid arthritis (RA) at the initial presentation in seropositive (anti-citrullinated protein antibody (ACPA) and/or rheumatoid factor (RF) positive) and negative patients and the effect of duration of symptoms on the clinical picture.

Methods: Data of patients who received reimbursement for DMARDs for newly diagnosed RA in 1/2019 to 9/2021 were extracted from the national databases. Joint counts, presence of symmetrical swelling, other disease activity measures, and patient reported outcomes (PROs) were compared in seropositive and negative patients.

Disease burden measured by patient-reported outcomes: does psoriatic arthritis feel worse than rheumatoid arthritis? A cross-sectional nationwide study.

Objectives: To study the subjective disease burden of patients with psoriatic arthritis (PsA) and rheumatoid arthritis (RA), using patient-reported outcomes (PROs) cross-sectionally.

Methods: Data of 3598 patients with PsA and 13913 with RA were extracted from the database. Measures included the VAS-values of pain, fatigue and patient global assessment (PGA), HAQ, and disease activity at the most recent visit/remote contact in the period 1.

Dietary Intervention in Infancy and Cognitive Function in Young Adulthood: The Special Turku Coronary Risk Factor Intervention Project.

Objective: Consumption of saturated fatty acids (SAFAs), polyunsaturated fatty acids (PUFAs), cholesterol, and fiber have been linked with cognitive function in adults. We evaluated these associations from childhood by leveraging data from the Special Turku Coronary Risk Factor Intervention Project (STRIP).

Study Design: STRIP recruited children aged 5 months and randomly assigned them into intervention/control groups.

Temperament and Early Intentions to Retire: A Northern Finland Birth Cohort 1966 Study.

Objective: To examine associations between temperament traits and early retirement intentions.

Methods: In the Northern Finland Birth Cohort 1966, we analyzed early retirement intentions at the age 46 according to Cloninger temperament traits at the age 46 (n = 4409) and at the age 31 (n = 3226). Ordinal logistic regression analyses were used.

Use of psychiatric medications in schizophrenia and other psychoses in a general population sample.

The information on the use of psychiatric medications in general population-based samples is limited. Our aim was to analyse the use of psychiatric medications and factors associated with antipsychotic use in psychoses in a general population sample. Fifty-five persons with schizophrenia, 21 with bipolar psychosis or psychotic depression and 20 with other psychoses from the Northern Finland Birth Cohort 1966 were examined at about 43 years of age.

Poor premorbid school performance, but not severity of illness, predicts cognitive decline in schizophrenia in midlife.

Neurocognitive dysfunction is common in schizophrenia but its course and determinants remain uncertain. Our aim was to analyse if premorbid school performance and the severity of illness and functioning predict change in cognition in schizophrenia in a general population sample. The sample included cases with schizophrenia spectrum disorder from the Northern Finland Birth Cohort 1966.
