Recognising the growing global burden of fungal infections, the World Health Organization (WHO) established an advisory group consisting of experts in fungal diseases to develop a Fungal Priority Pathogen List. Pathogens were ranked based on their research and development needs and perceived public health importance using a series of global surveys and pathogen characteristics derived from systematic reviews. This systematic review evaluates the features and global impact of invasive disease caused by Candida glabrata (Nakaseomyces glabrata).

Article Synopsis
  • The World Health Organization initiated a fungal pathogen priority list due to the rising threat of fungal diseases, focusing on the epidemiology of Talaromyces marneffei, Coccidioides species, and Paracoccidioides species.
  • A total of 48 studies were reviewed, revealing high mortality rates for invasive infections (up to 22.7%) and frequent hospitalizations for coccidioidomycosis (up to 84%), often with readmission.
  • There is evidence of reduced effectiveness of certain antifungals against some species, with risk factors for mortality related to CD4 counts, and outbreaks commonly linked to construction activities; increased surveillance and further studies are needed.

Purpose: Open-access publishing expanded opportunities to give visibility to research results but was accompanied by the proliferation of predatory journals (PJos) that offer expedited publishing but potentially compromise the integrity of research and peer review. To our knowledge, to date, there is no comprehensive global study on the impact of PJos in the field of oncology.

Materials And Methods: A 29 question-based cross-sectional survey was developed to explore knowledge and practices of predatory publishing and analyzed using descriptive statistics and binary logistic regression.

Background: Patients with cancer in low- and middle-income countries experience worse outcomes as a result of the limited capacity of health systems to deliver comprehensive cancer care. The health workforce is a key component of health systems; however, deep gaps exist in the availability and accessibility of cancer care providers.

Materials And Methods: We carried out a systematic review of the literature evaluating the strategies for capacity building of the cancer workforce.

Article Synopsis
  • Previous studies linked cancer diagnoses with increased COVID-19 death risk, but many didn’t differentiate between long-term survivors and those recently diagnosed or treated, nor did they consider age factors.
  • The research aimed to provide clearer evidence regarding the risk of COVID-19-related death in individuals with active or recent cancers during the pre-vaccination period, analyzing 39 studies that adjusted for age and gender.
  • Results indicated that people with recent cancer diagnoses have a significantly higher risk of dying from COVID-19, especially for those with lung or hematological cancers, with the risk decreasing over time since treatment.

Background: Cancer is a global public health problem, requiring efficient health system investments to deliver sustainable impact on population health. Access to medicines is a critical component of health systems, having a crucial role in delivering therapeutic benefits. Since 1977, the World Health Organization (WHO) has published a Model List of Essential Medicines (EML) that includes key health interventions for the prevention and control of conditions of public health relevance.

Background: The European Society for Medical Oncology-Magnitude of Clinical Benefit Scale (ESMO-MCBS) has been developed to grade clinical benefit of cancer therapies. Improvement in quality of life (QoL) is considered relevant, especially in the non-curative setting. This is reflected by an upgrade of the preliminary ESMO-MCBS score if QoL is improved compared to the control arm or a downgrade if an improvement in progression-free survival is not paralleled by an improvement in QoL or overall survival.

Background: The invasion of Ukraine by Russia in February 2022 has resulted in destruction of healthcare infrastructure and triggered the largest wave of internally displaced populations and refugees since World War Two. Conflicts in transitioned countries such as Ukraine create new non-communicable disease (NCD) challenges, especially for cancer care for refugees and humanitarian assistance in host countries. In the early days, rapid attempts were made to model possible impacts.

Oral cancer (OC) is a debilitating disease with a high mortality rate when diagnosed in advanced stage. Conversely, early-stage OC has a high survival rate, supporting a need for early detection programmes. A previous systematic review of clinical trials evaluating efficacy of screening for OC was inconclusive.

Before 2005, cancer and other non-communicable diseases were not yet health and development agenda priorities. Since the 2005 World Health Assembly Resolution, which encouraged WHO, the International Agency for Research on Cancer (IARC), and the International Atomic Energy Agency (IAEA) to jointly work on cancer control, progress was achieved in low-income and middle-income countries on a small scale. Recently, rapid acceleration in UN collaboration and global cancer activities has focused attention in global cancer control.

Background: Advances in cancer medicines have resulted in tangible health impacts, but the magnitude of benefits of approved cancer medicines could vary greatly. Health Technology Assessment (HTA) is a multidisciplinary process used to inform resource allocation through a systematic value assessment of health technology. This paper reviews the challenges in conducting HTA for cancer medicines arising from oncology trial designs and uncertainties of safety-efficacy data.
