Background: Mild traumatic brain injury (mTBI), commonly known as concussion, is a major public health issue characterized by subtle neuronal damage that traditional imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) often fail to detect. Fluid biomarkers have emerged as promising diagnostic and prognostic tools for mTBI. Objectives: This umbrella meta-analysis aims to evaluate the diagnostic accuracy and clinical utility of the key fluid biomarkers, S100B, glial fibrillary acidic protein (GFAP), ubiquitin carboxy-terminal hydrolase L1 (UCH-L1, neurofilament light chain (NfL)) and tau protein, in detecting mTBI and to clarify their roles as screening, confirmatory, and complementary indicators. Methods: A systematic review was performed using PubMed, Web of Science, Scopus, and Cochrane to identify the published meta-analyses that assessed the biomarkers in mTBI. Sensitivity, specificity, and diagnostic odds ratios were then calculated using random-effects models. Heterogeneity was evaluated with the I2 statistic, and publication bias was assessed via funnel plots. The results of S100B demonstrated high sensitivity (91.6%) but low specificity (42.4%), making it an effective rule-out biomarker to minimize unnecessary CT scans. In contrast, GFAP exhibited moderate sensitivity (84.5%) with improved specificity (61.0%), supporting its role in confirming mTBI diagnoses. UCH-L1 revealed a sensitivity of 86.7% alongside low specificity (37.3%), indicating its potential as a complementary marker. Additionally, the NfL levels were notably elevated in sports-related concussions, while the diagnostic utility of tau protein remains inconclusive due to limited available data. Conclusions: The findings underscore the clinical promise of fluid biomarkers in the management of mTBI. S100B and GFAP are particularly valuable as screening and confirmatory markers, respectively. Nonetheless, further standardization of biomarker thresholds and additional longitudinal studies are necessary to validate the roles of UCH-L1, NfL, and Tau protein. The integration of these biomarkers into a multimodal diagnostic panel may enhance mTBI detection accuracy and facilitate improved patient stratification and management.

The purpose of this study is to assess the association between digital biomarkers on diet compliance and other health-related outcomes in adults willing to change their eating behaviours. This study employed a mixed-method, cross-sectional design with 100 participants over three months. Basic demographic and clinical data were obtained, and self-monitoring was done using digital biomarkers of diet and physical activity. The dietary compliance level was measured pre- and post-intervention using a dietary questionnaire. Quantitative analyses included paired t-tests, correlation, regression, and mediation analyses to assess the impact of digital biomarkers on nutritional and health outcomes. There was a statistically significant improvement in dietary adherence scores post-intervention (t = 9.61, p < 0.001). A positive relationship was found between digital biomarker use and diet consumption (r = 0.45, p < 0.001) and weight loss (r = 0.32, p < 0.05). Regression analysis indicated that baseline dietary adherence and biomarker use were significant predictors of weight loss (F (1, 22) = 7.92; p < 0.001 and F (1,22) = 7.69; p < 0.01), though the model explained only 20% of variance, suggesting other influencing factors. This study identified usefulness, motivation, and responsibility as key themes related to digital biomarker use. Digital biomarkers hold potential for enhancing personalised nutrition interventions and adherence to dietary recommendations. Future research should focus on data privacy, user involvement, and improving AI algorithms for clinical implementation.

In Romania, as in other parts of the world, the family doctor is the first to make contact with a healthy patient and is also the first to notice even the smallest pathological changes. In the context of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, the patient's communication with the family doctor became even closer and some behavioral changes could be easily noticed. To assess the symptoms of anxiety and depression in the Romanian population using social media platforms in the context of the COVID-19 pandemic. We conducted an anonymous, web-based cross-sectional survey consisting of 31 questions related to general characteristics (age, gender, education, inhabitancy, residence, smoking status, and alcohol consumption) and adapted GAD-7 (7-item General Anxiety Disorders questionnaire) and PHQ-9 (9-item Patient Health Questionnaire). This questionnaire was sent to volunteers in an electronic format through a social network (Facebook, Twitter). The data collected were statistically processed using IBM SPSS v25.0 (IBM Corp., Armonk, NY). The inclusion criteria were age over 18 years and no history of chronic disease. The exclusion criteria consisted of the absence of a mental illness diagnosis. From the 1254 respondents, 1232 cases were selected for statistical analysis after applying the exclusion criteria. The mean age was 35.94 (SD = 11.4, 95%CI=10.9-11.9) with a minimum of 18 years and a maximum of 97 years. Eighty-four point nine percent (84.9%; N=1046) of all study participants are female and 79.13% (N= 975) live in the urban area. A total of 188 (15.25%) were diagnosed with COVID-19 of which 31 (16.66%) were male and 157 (15%) were female. N=170 (13.8%) reported moderate symptoms of anxiety during the last two weeks before the survey while N=96 (7.8%) had severe anxiety. Twenty-two point two percent (22.2%; N=274) of the participants reported moderate symptoms of depression while 10.1% (N=125) had moderately severe symptoms and 6.6% (N=81) could be diagnosed with severe depression. A greater likelihood of screening for depression diagnosis was associated with ages between 25 and 34 years (OR=0.90, 95%CI=0.86-0.94, P<.001), 35 and 44 years (OR=0.88, 95%CI=0.84-0.93, P<.001), and 45 and 54 years (OR=0.87, 95%CI=0.82-0.92, P<.001). Also, a tendency was observed for women to be more prone to high levels of anxiety (OR=1.21, 95%CI=1.08-1.35, P< .001) and depression (OR=2.16, 95%CI=1.51-308, P< .005). Regarding the high prevalence of depression and anxiety, especially in women, appropriate measures for the risk categories should be applied. In the new social context created by the COVID-19 pandemic, screening for psychiatric and psychological disorders should be performed by telemedicine.

The COVID-19 pandemic has introduced new challenges in managing neurological conditions, particularly among athletes. This paper explores the intersection of post-COVID-19 neurological syndrome (PCNS/PASC) and post-concussion syndrome (PCS), focusing on their implications in sports medicine. Our analysis covers the symptomatology, pathophysiology, and management strategies for PCNS/PASC and PPCS, with special attention paid to the unique challenges faced by athletes recovering from these conditions, including the risk of symptom exacerbation and prolonged recovery. Key findings reveal that both PCNS/PASC and PPCS present with overlapping symptoms such as cognitive difficulties, exercise intolerance, and mental health issues, but differ in specific manifestations like anosmia and ageusia, unique to COVID-19. Pathophysiological analysis reveals similarities in blood–brain barrier disruption (BBB) but differences in the extent of immune activation. Management strategies emphasize a gradual increase in physical activity, close symptom monitoring, and psychological support, with a tailored approach for athletes. Specific interventions include progressive aerobic exercises, resistance training, and cognitive rehabilitation. Furthermore, our study highlights the importance of integrating neurology, psychiatry, physical therapy, and sports medicine to develop comprehensive care strategies. Our findings underscore the dual challenge of COVID-19 and concussion in athletes, necessitating a nuanced, interdisciplinary approach to effective management. Future research should focus on the long-term neurological effects of both conditions and optimizing treatment protocols to improve patient outcomes. This comprehensive understanding is crucial for advancing the management of athletes affected by these overlapping conditions and ensuring their safe return to sports.

The aim of this paper is to describe the temporal progression and clinical picture of a 2-year-old child with infantile Refsum disease, as well as the diagnostic procedures performed; this case presented multiple hematologic, metabolic, and developmental complications and progressive disabilities. Genetic testing revealed a mutation of the PEX6 (Peroxisomal Biogenesis Factor 6) gene, and the metabolic profile was consistent with the diagnosis. Particularly, the child also presented altered coagulation factors and developed a spontaneous brain hemorrhage. The clinical picture includes several neurological, ophthalmological, digestive, cutaneous, and endocrine disorders as a result of the very long chain fatty acid accumulation as well as secondary oxidative anomalies. The study of metabolic disorders occurring because of genetic mutations is a subject of core importance in the pathology of children today. The PEX mutations, difficult to identify antepartum, are linked to an array of cell anomalies with severe consequences on the patient’s status, afflicting multiple organs and systems. This is the reason for which our case history may be relevant, including a vast number of symptoms, as well as modified biological parameters.

Human milk is widely recognised as the optimal source of nutrition for newborns and infants, providing not only an ideal macronutrient composition but also a range of bioactive components that exert important non-nutritional functions, and as such it represents the first functional food consumed in early life. Among these bioactive components, the human milk oligosaccharides (HMOs)—a structurally diverse family of glycans present in human milk at concentrations 100- to 1000-fold higher than in the milk of other mammalian species—have emerged as multifunctional contributors to the establishment of the intestinal microbiome, immune development, anti-infective defence, and epithelial barrier integrity during a developmental window characterised by immune immaturity. The aim of the present narrative review is to synthesise current evidence on the anti-infective properties of HMOs in infancy and to integrate, within a single framework, five interconnected mechanisms through which HMOs protect the infant against infection: glycan-mimicry-based competitive inhibition of pathogen adhesion, direct antimicrobial and antibiofilm activity, selective prebiotic shaping of the gut microbiome, modulation of innate and adaptive immune responses, and reinforcement of mucosal barrier integrity in the gut and lungs. Breastfeeding constitutes a natural strategy for anti-infective protection in early childhood, while infant formulas supplemented with biotechnologically produced HMOs that are structurally identical to those in human milk provide measurable benefits for non-breastfed infants.
