Para athletes present a broad range of sports-related injuries and illnesses, frequently encountering barriers when accessing healthcare services. The periodic health evaluation (PHE) is a valuable tool for continuously monitoring athletes' health, screening for health conditions, assisting in the surveillance of health problems by establishing baseline information and identifying barriers to athlete's performance. This position statement aims to guide sports healthcare providers in the PHE for Para athletes across key impairment categories: intellectual, musculoskeletal, neurological and vision.

The prevalence of Metabolic-associated fatty liver disease (MAFLD) has been steadily increasing worldwide, paralleling the global epidemic of obesity and diabetes. It is estimated that approximately one-quarter of the global population is affected by MAFLD. Despite its high prevalence, MAFLD often goes undiagnosed due to the lack of specific symptoms in its early stages.

Colorectal cancer (CRC) is the third most frequent cancer worldwide and the second major cause of cancer-related death. Thus, we attempted to ascertain the relationship between the genotype and allele frequencies of phosphatase and tensin homolog (PTEN) and immunohistochemical PTEN expression with clinicopathological characteristics in patients with CRC. 150 individuals were allocated into two groups for this cross-sectional randomized case-control study: Group I consisted of 100 patients with histopathologically proven CRC of various stages.

Objectives: To investigate if the sport concussion assessment tool version 5 (SCAT5) could be suitable for application to Para athletes with a visual impairment, a spinal cord injury, or a limb deficiency.

Methods: A 16-member expert panel performed a Delphi technique protocol. The first round encompassed an open-ended questionnaire, with round 2 onwards being composed of a series of closed-ended statements requiring each expert's opinion using a five-point Likert scale.

This study aimed to examine the immunohistochemical expression of epithelial-mesenchymal transition biomarkers: P4HA2 and SLUG in colorectal carcinoma (CRC) specimens, then to assess their relation to clinicopathological features including KRAS mutations and patients' survival, and finally to study the correlation between them in CRC. The result of this study showed that SLUG and P4HA2 were significantly higher in association with adverse prognostic factors: presence of lympho-vascular invasion, perineural invasion, higher tumor budding, tumor stage, presence of lymph node metastasis, and presence of distant metastasis. CRC specimens with KRAS mutation were associated with significant higher SLUG and P4HA2 expression.

Although research on sport-related concussion has grown substantially in the last decade, research on concussion in para sports remains limited. The aim of this scoping review is to synthesize and describe the current literature on the incidence, assessment, and management of sport-related concussion in para athletes. The literature search was conducted in CINAHL, Google Scholar, MEDLINE, SPORTDiscus, and Web of Science databases and identified 22 studies that addressed one of our research questions.

Article Synopsis
  • The 6th International Conference on Concussion in Sport took place in Amsterdam from October 27-30, 2022, leading to a new consensus statement and updates on concussion protocols.
  • In preparation, author groups conducted extensive systematic reviews over 3½ years on key concussion-related topics, informing the conference discussions and outcomes.
  • The conference introduced revised tools like CRT6 and SCAT6, emphasized the importance of the para athlete's perspective, and highlighted gaps in research concerning concussion prevention and long-term effects.

The purpose of this paper is to summarise the consensus methodology that was used to inform the International Consensus Statement on Concussion in Sport (Amsterdam 2022). Building on a Delphi process to inform the questions and outcomes from the 5th International Conference on Concussion in Sport, the Scientific Committee identified key questions, the answers to which would help encapsulate the current science in sport-related concussion and help guide clinical practice. Over 3½ years, delayed by 2 years due to the pandemic, author groups conducted systematic reviews on each selected topic.

Article Synopsis
  • The study aimed to investigate how the MIF gene polymorphism rs755622 G>C influences the development and severity of hepatocellular carcinoma (HCC) in Egyptian patients.
  • It included 50 HCC patients and 50 healthy individuals, analyzing data through various scoring systems and genetic testing.
  • Results revealed that specific genotypes (GG and GC) of the MIF gene occurred more frequently in HCC patients, particularly those with advanced liver disease, indicating a potential link between this genetic variant and HCC progression.

Introduction: HCC is frequently diagnosed late, when only palliative treatment is available. So, we try to use different immunological markers to identify early HCC in patients with unremarkable raised AFP.

Methods: This study was conducted on 112 participants divided into two equal groups: Group I, 56 patients with liver cirrhosis and different stages of HCC; Group II, 56 patients with liver cirrhosis.

Objectives: Athletes with impairments play sports with a risk of sustaining head injuries and concussions. However, the scientific knowledge needed to improve care is lacking. This qualitative study explores English blind 5-a-side footballers' perceptions of concussion, concussion risks and prevention to improve para concussion care.
