AI Article Synopsis

  • This review examines the prevalent aetiological perspectives in the literature surrounding three major functional somatic syndromes: fibromyalgia syndrome (FMS), irritable bowel syndrome (IBS), and chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), alongside their psychiatric classifications.
  • A total of 452 reviews were analyzed, revealing that 90% discussed biological factors, while psychological, social, and healthcare factors were mentioned less frequently, with low methodological quality noted in many of the systematic reviews.
  • The authors emphasize the need for future research to adopt a thorough biopsychosocial approach in studying aetiological factors for functional somatic syndromes, moving beyond simplistic models and improving scientific rigor.

Article Abstract

Background: This umbrella review systematically assesses the variety and relative dominance of current aetiological views within the scientific literature for the three most investigated symptom-defined functional somatic syndromes (FSS) and their classificatory analogues within psychiatry and psychology.

Method: An umbrella review of narrative and systematic reviews with and without meta-analyses based on a search of electronic databases (PubMed, Web of Science, Embase, PsychINFO) was conducted. Eligible reviews were published in English, focused on research of any kind of aetiological factors in adults diagnosed with fibromyalgia syndrome (FMS), irritable bowel syndrome (IBS), chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), and somatic symptom disorder (SSD)/somatoform disorder (SFD).

Results: We included 452 reviews (132 systematic reviews including meta-analyses, 133 systematic reviews, 197 narrative reviews), of which 132 (29%) focused on two or more of the investigated health conditions simultaneously. Across diagnoses, biological factors were addressed in 90% (k = 405), psychological in 33% (k = 150), social in 12% (k = 54), and healthcare factors in 5% (k = 23) of the reviews. The methodological quality of the included systematic reviews (k = 255) was low (low/critically low: 41% [k = 104]; moderate: 49% [k = 126]; high quality: 10% [k = 25]). The high-quality systematic reviews suggest that deficient conditioned pain modulation, genetic factors, changes in the immune, endocrinological, gastrointestinal, cardiovascular, and nervous system, and psychosocial factors such as sexual abuse and pain catastrophizing increase the risk for FSS.

Conclusion: Only very few systematic reviews have used comprehensive, biopsychosocial disease models to guide the selection of aetiological factors in FSS research. Future research should strive for higher scientific standards and broaden its perspective on these health conditions.

Background: Forecasting future public pharmaceutical expenditure is a challenge for healthcare payers, particularly owing to the unpredictability of new market introductions and their economic impact. No best-practice forecasting methods have been established so far. The literature distinguishes between the top-down approach, based on historical trends, and the bottom-up approach, using a combination of historical and horizon scanning data.

Introduction: The aim of this study was to establish an international consensus statement on the indications for the addition of a patellofemoral joint arthroplasty (PFJA) in patients with a unicondylar knee arthroplasty (UKA) and symptomatic progression of patellofemoral compartment osteoarthritis.

Materials And Methods: A systematic review of the literature was conducted, and the results used to inform the development of a statement by an expert working group. This was then evaluated and modified, using a Delphi process, by members of the European Knee Society (EKS).

Introduction: Ankle fractures represent a significant portion of orthopedic injuries, with fracture dislocations tending to have worse outcomes. Logsplitter fractures represent a subset of fracture dislocations in which the talus is axially wedged in the tibiofibular joint. We aim to comprehensively investigate and report on the complications and functional outcomes associated with ankle fracture-dislocations.

Introduction: Liquid biopsy as a non-invasive method to investigate cancer biology and monitor residual disease has gained significance in clinical practice over the years. Whilst its applicability in carcinomas is well established, the low incidence and heterogeneity of bone and soft tissue sarcomas explains the less well-established knowledge considering liquid biopsy in these highly malignant mesenchymal neoplasms.

Materials And Methods: A systematic literature review adhering to the PRISMA guidelines initially identified 920 studies, of whom 68 original articles could be finally included, all dealing with clinical applicability of liquid biopsy in sarcoma.

Patients with hard-to-heal wounds: a review and synthesis of their experiences and perceptions of maggot debridement.

Alice Lee Centre for Nursing Studies, Yong Loo Lin School of Medicine, National University of Singapore, Clinical Research Centre, Singapore.

Objective: There is little use of maggot debridement therapy (MDT) worldwide, albeit there is much literature supporting its benefits and effectiveness for hard-to-heal (chronic) wounds. Hard-to-heal wounds are becoming ever more prevalent and MDT can play a pivotal role in wound care management. This underuse can be associated with patients' perceptions and experiences of MDT.
