Background/objectives: To evaluate the health benefits, costs, and cost-effectiveness of vaccination with bivalent respiratory syncytial virus stabilized prefusion F vaccine (RSVpreF) for the prevention of lower respiratory tract disease caused by respiratory syncytial virus (RSV) in Greek adults 60 years of age and older.

Methods: A Markov model was adapted to simulate lifetime risk of health and economic outcomes from the public payer's perspective over a lifetime horizon. Epidemiology, vaccine effectiveness, utilities, and direct medical costs (EUR, 2024) were obtained from published studies, official sources, and local experts.

Article Synopsis
  • Ankylosing spondylitis is a chronic inflammatory disease affecting the spine and quality of life, and this study aimed to compare the cost-effectiveness of tofacitinib with existing biologic treatments in Greece for patients not responding to traditional therapies.
  • The analysis utilized a decision tree and a Markov model to evaluate treatment effectiveness by measuring patient outcomes like disease activity and functional score improvements while considering treatment costs and potential adverse effects.
  • Results indicated that tofacitinib may offer increased quality-adjusted life-years compared to adalimumab in patients who are new to biologic therapies, potentially leading to a more favorable cost-effectiveness profile.

Objective: Higher valency pneumococcal conjugate vaccines (PCVs) are expected to improve protection against pneumococcal disease through coverage of additional serotypes. The aim of the present study was to evaluate the cost-effectiveness of 20-valent pneumococcal conjugate vaccine (PCV20) compared to 15-valent pneumococcal conjugate vaccine (PCV15) alone or followed by 23-valent polysaccharide vaccine (PPV23) for adults in Greece.

Methods: A published Markov model was adapted to simulate lifetime risk of clinical and economic outcomes from the public payer's perspective.

In June 2010, Greece introduced the 13-valent pneumococcal conjugate vaccine (PCV13) for pediatric vaccination and has since observed a large decrease in pneumococcal disease caused by these vaccine serotypes, yet the disease prevalence of non-vaccine serotypes has increased. Two higher-valent conjugate vaccines, a 15-valent (PCV15) and a 20-valent (PCV20), were developed to improve serotype coverage and combat serotype replacement. A decision-analytic model was adapted to the Greek setting using historical pneumococcal disease trends from PCV13 to forecast future clinical and economic outcomes of higher-valent PCVs over a 10-year period (2023-2033).

MPPs are trained in the branches of physics associated with the practice of medicine. Possessing a solid scientific background and technical skills, MPPs are well suited to play a leading role within each stage of a medical device life cycle. The various stages of the life cycle of a medical device include establishment of requirements with use-case assessment, investment planning, procurement of medical devices, acceptance testing especially regarding safety and performance, quality management, effective and safe use and maintenance, user training, interfacing with IT systems, and safe decommissioning and removal of the medical devices.

Article Synopsis
  • The study identified and validated thermal stress indicators (TSIs) through field experiments involving 372 workers across nine countries, monitoring their physiological responses to heat.
  • Nearly all TSIs showed strong correlations with key health indicators such as mean skin temperature and heart rate, highlighting the limitations of basic meteorological parameters.
  • Among 61 TSIs evaluated, the Wet-Bulb Globe Temperature and Universal Thermal Climate Index scored the highest in assessing heat stress, indicating their effectiveness in monitoring workers' physiological strain.

Background And Objective: Acute lymphoblastic leukemia (ALL) is an acute, rapidly progressing and life-threatening form of cancer involving immature lymphocytes called lymphoblasts. ALL is the most common subtype of leukemia in children and adolescents. The aim of the present study was to assess the cost-utility of pegaspargase versus L-asparaginase, both followed by Erwinase in the therapy sequence, as a treatment option for pediatric, adolescent, and adult patients with ALL in Greece.

Article Synopsis
  • The study identifies and validates 17 thermal stress indicators (TSIs) crucial for protecting individuals working in heat through expert consensus.
  • The criteria evaluated include physiological measures (like body temperature and hydration) and factors such as practicality and cost-effectiveness, distributed among three safety pillars: occupational health, physiological strain mitigation, and cost-efficiency.
  • Key findings reveal that certain criteria—like the correlation of TSIs with core temperature and the ability to categorize heat stress levels—are particularly vital in selecting appropriate TSIs, with emphasis on improving worker safety.

Non-small cell lung cancer (NSCLC), which accounts for about 80%-85% of lungcancer cases, is a leading cause of cancer-related death worldwide. Lorlatinib is a potent third-generation anaplastic lymphoma kinase (ALK) inhibitor approved for the treatment of patients with advanced, ALK-positive NSCLC previously treated with at least one second-generation ALK tyrosine kinase inhibitor. The present study assessed the cost-effectiveness of lorlatinib vs pemetrexed with platinum combination of carboplatin or cisplatin (P-ChT) in Greece.

Background: The electromagnetic spectrum spans over an enormous range from 0 up to more than 1020 Hz in the deep ionizing region, significant exposures exist in specific occupational environments. Between the ionizing and the electromagnetic fields (EMF) part of the spectrum, the 'optical radiation' (OR) region has specific properties. Comparative and concise evaluation enables action prioritization.

Background And Objective: Hemophilia A (HA) is a rare disease that is characterized by congenital underproduction or dysfunction of the endogenous coagulation factor VIII (FVIII). The aim of the present study was to determine the value of prophylaxis versus on-demand treatment strategies for moderate to severe HA (MtSHA) patients and the value of emicizumab in the prophylaxis of MtSHA in Greece, compared with short half-life (SHL) FVIII and extended half-life (EHL) FVIII through multicriteria decision analysis (MCDA).

Methods: A literature review was performed to identify a set of criteria relevant to the therapeutic approaches and therapies under investigation.

Background And Objective: Type 2 diabetes mellitus (T2DM) is frequently associated with co-morbidities that exacerbate cardiovascular (CV) risk. CV disease is the leading cause of death in people with diabetes across the world and accounts for approximately half the deaths in the T2DM population. Hence, the objective of present study was to evaluate the cost-effectiveness of empagliflozin, in addition to standard of care (SoC), for the treatment of adult patients with T2DM and high CV risk in Greece.
