Background: C-reactive protein (CRP) is one of the most commonly monitored inflammatory markers in patients with COVID-19 to gain insight into the inflammation level in the body and to adopt effective disease management and therapeutic strategies. COVID-19 is now less prevalent, and the study of CRP as a biomarker of inflammation still needs deeper understanding, particularly in understanding its role among patients with comorbidities, which are known to influence inflammatory responses and increase the risk of severe outcomes during acute and chronic infectious diseases. The objective of this study was to evaluate the association of major comorbidities such as ischemic heart diseases, diabetes, chronic kidney disease, hypertension, and lung infections e.

Mammalian fertilization is a complex and highly regulated process that has garnered significant attention, particularly with advancements in assisted reproductive technologies such as in vitro fertilization (IVF). The fusion of egg and sperm involves a sequence of molecular and cellular events, including capacitation, the acrosome reaction, adhesion, and membrane fusion. Critical genetic factors, such as IZUMO1, JUNO (also known as FOLR4), CD9, and several others, have been identified as essential mediators in sperm-egg recognition and membrane fusion.

Inborn errors of selenoprotein expression arise from deleterious variants in genes encoding selenoproteins or selenoprotein biosynthetic factors, some of which are associated with neurodegenerative disorders. This study shows that bi-allelic selenocysteine tRNA-specific eukaryotic elongation factor (EEFSEC) variants cause selenoprotein deficiency, leading to progressive neurodegeneration. EEFSEC deficiency, an autosomal recessive disorder, manifests with global developmental delay, progressive spasticity, ataxia, and seizures.

Article Synopsis
  • Venous thromboembolism (VTE) is a major health issue, particularly affecting the elderly, leading to high recurrence rates and increased healthcare costs, prompting the study to assess the impact of a VTE risk assessment tool and thromboprophylaxis in hospitalized patients.
  • Conducted in a tertiary hospital in Pakistan, the study evaluated 1,200 adult inpatients, finding that only 15.83% of medical records documented a VTE risk assessment, and thromboprophylaxis was prescribed to just 37.5% of patients.
  • The findings highlight that many hospitalized patients are at high risk for VTE, primarily due to old age, yet the implementation of VTE risk assessments and the use of

Visual perceptual artefacts are distortions or illusions in medical image interpretation arising from the human visual system rather than hardware or imaging acquisition processes. These artefacts, emerging at various visual processing stages, such as the retina, visual pathways, visual cortex, and cognitive interpretation stages, impact the interpretation of cardiothoracic images. This review discusses artefacts including Mach bands, Dark Rim, Background Effects, Ambiguous Figures, Subjective Contours, and the Parallax Effect.

Transformer-based Large Language Models (LLMs) have recently increased in popularity, in part due to their impressive performance on a number of language tasks. While LLMs can produce human-like writing, the extent to which these models can learn to predict spoken language in natural interaction remains unclear. This is a nontrivial question, as spoken and written language differ in syntax, pragmatics, and norms that interlocutors follow.
