Cerebral Small Vessel Disease (CSVD), a progressive degenerative disorder of small caliber cerebral vessels, represents a major contributor to stroke and vascular dementia incidence worldwide. We sought to conduct a systematic review of the role of retinal biomarkers in diagnosis and characterization of CSVD.
We conducted a systematic review of MEDLINE, PubMed, Scopus, the Cochrane Library Database, and Web of Science. We identified studies of sporadic CSVD (including CSVD not otherwise specified, Cerebral Amyloid Angiopathy, and Hypertensive Arteriopathy) and the most common familial CSVD disorders (including CADASIL, Fabry disease, and MELAS). Included studies used one or more of the following tools: visual fields assessment, fundus photography, Optical Coherence Tomography and OCT Angiography, Fluorescein Angiography, Electroretinography, and Visual Evoked Potentials.
We identified 48 studies of retinal biomarkers in CSVD, including 9147 cases and 12276 controls. Abnormalities in retinal vessel diameter (11 reports, n = 11391 participants), increased retinal vessel tortuosity (11 reports, n = 617 participants), decreased vessel fractal dimension (5 reports, n = 1597 participants) and decreased retinal nerve fiber layer thickness (5 reports, n = 4509 participants) were the biomarkers most frequently associated with CSVD. We identified no reports conducting longitudinal retinal evaluations of CSVD, or systematically evaluating diagnostic performance.
Multiple retinal biomarkers were associated with CSVD or its validated neuroimaging biomarkers. However, existing evidence is limited by several shortcomings, chiefly small sample size and unstandardized approaches to both biomarkers' capture and CSVD characterization. Additional larger studies will be required to definitively determine whether retinal biomarkers could be successfully incorporated in future research efforts and clinical practice.

Objectives: Corporate health programs (CHPs) aim to improve employees’ health through health promotion strategies at the workplace. Physical activity (PA) plays a crucial role in primary prevention, leading many companies to implement PA-based CHPs. However, there is limited examination in the scientific literature on whether PA-based CHPs (PA-CHPs) lead to economic benefits. This systematic review aimed to summarize the available literature on the economic aspects of PA-CHPs.Methods: A systematic review was conducted to identify studies focused on PA-CHPs targeting healthy sedentary workers and reporting at least one economic outcome, such as return on investment (ROI), costs, or sick leave.Results: Of 1036 studies identified by our search strategy, 11 studies involving 60 020 participants met the inclusion criteria. The mean (±SD) cost per capita for PA-CHPs was estimated as 359€ (±238€) (95% CI, 357-361€). In 75% of the studies, the net savings generated by PA-CHPs in 12 months were reported, with an average of 1095€ (±865€) (95% CI, 496-1690€). ROI was assessed in 50% of the included studies, with an average of 3.6 (±1.41) (95% CI, 2.19-5.01).Conclusions: In addition to promoting a healthy lifestyle, PA-CHPs have the potential to generate significant economic returns. However, the heterogeneity among the existing studies highlights the need for standardization and accurate reporting of costs in future research.

The aim of our study was to evaluate the prevalence, awareness, and control of hypertension in an apparently healthy company population. We conducted a cross-sectional study on a total sample of 2058 individuals with a mean age of 38 ± 9 years, enrolled for the first time to the Ferrari corporate wellness program “Formula Benessere”. Hypertension was defined as systolic blood pressure (SBP) level ≥140 mmHg or diastolic BP (DBP) ≥90 mmHg or use of antihypertensive medication, whereas BP control was defined as BP level <130/80 mmHg. All 2058 participants were divided into three groups based on age: Group 1 aged <40 years (n = 1177, 57%), Group 2 aged 40–50 years (n = 627, 30%), and Group 3 aged >50 years (n = 254, 13%). Four-hundred and one subjects had BP levels ≥130/80 mmHg (19.5%). Two-hundred and sixty-one individuals (12.7%) had high-normal BP values and 140 subjects had rest SBP ≥140 mmHg and/or DBP ≥90 mmHg (6,8%), of which 41 (29.3%) with grade 2 hypertension. In the overall population, 259 individuals (12.5%) were affected by hypertension, the prevalence increasing with age. Only a minority (51%) was aware of being hypertensive and already treated with antihypertensive medications (45.9%). An adequate BP control was achieved in only 57% of subjects who received BP-lowering therapy. Corporate wellness programs may represent an essential tool in identifying apparently healthy subjects with an inadequate control of cardiovascular (CV) risk factors, such as hypertension. These preventive programs in the workplace may help to improve and spread primary CV prevention at the population level.

Background. Poor posture is a common musculoskeletal concern in children and adolescents and may lead to spinal discomfort and long-term structural issues. While excess weight has been linked to altered sagittal alignment, the impact of sports participation on spinal posture remains unclear. This study aimed to investigate the associations between weight status, sports participation, and sagittal spinal alignment in a pediatric population. Methods. This cross-sectional study was conducted within the “Ferrari Formula Benessere” corporate wellness program and included 698 children aged 5 to 16 years. Sagittal Index (SI) was measured using a standardized plumb line technique. Body mass index (BMI) was calculated and classified according to the WHO growth standards. Sports participation was self-reported and grouped into five categories: sedentary, skill-based, power-based, mixed, and endurance sports. Results. Age was the only significant independent predictor of the SI (β = 2.45, p < 0.001), with older children exhibiting higher SI values. Although a weak correlation was observed between BMI and SI (Spearman’s r = 0.24, p < 0.001), BMI was not a significant predictor when controlling for age. No significant differences in the SI were found between active and non-active children. Among sport disciplines, the SI was lowest in power-based sports (56.7 ± 22.3 mm) and higher in endurance (62.7 ± 24.4 mm), mixed (64.5 ± 23.2 mm), skill-based (61.1 ± 22.0 mm), and non-sport (64.2 ± 24.0 mm) groups, although these differences did not reach statistical significance (ANOVA p = 0.224). Conclusions. Age appears to be the primary factor associated with sagittal spinal alignment in children, while BMI and general sports participation showed no independent effect. Although some differences emerged between sport types, these findings were not statistically significant and should be interpreted with caution. These findings underscore the need for sport-specific, longitudinal research using objective posture assessment methods.

Objectives: This work investigated the influence of anthropometric height on oculo-manual ability during a visuo-motor reaction time task. The aim was to determine whether aligning test configurations with individual stature changes performance outcomes. Methods: In the first phase, 450 participants completed a standardized reaction task using a fixed panel, and correlations were explored between anthropometric measures and performance. The results revealed significant inverse correlations between height and both reaction time total time, and reaction time intertime. A second experimental phase involved an additional group of 36 individuals, who completed the same task using both the fixed and adjustable panels, designed to align visual stimuli with each participant’s central line of sight and arm length. Results: A paired-sample t-test showed a statistically significant reduction in both reaction time total time, total time required to deactivate all 54 lights targets, (32.1±3.26 s to 30.7±2.58 s, p<0.05) and reaction time intertime, average time interval between successive light deactivations out of a total of 54 lights, (0.31±0.123 s to 0.21±0.149 s, p<0.01), time total time, total time required to deactivate all 54 lights targets, (32.1±3.26 s to 30.7±2.58 s, p<0.05) and reaction time intertime, average time interval between successive light deactivations out of a total of 54 lights, (0.31±0.123 s to 0.21±0.149 s, p<0.01) under the adjustable panel configuration. Conclusions: These findings suggest that standard testing configurations may disadvantage individuals with shorter stature and highlight the benefits of personalized setups for assessing and enhancing oculo-manual coordination.

During the COVID-19 lockdown, especially in the first wave of pandemic (March 2020), sedentary lifestyle and calorie intake increase in children became considerably more prevalent. The aim of the present paper was to evaluate changes in children’s weights and nutritional habits during the COVID-19 pandemic in Italy. In this cross-sectional observational study, for 3 years, as part of the corporate wellness program (2019–2021) in Emilia Romagna region of Italy, anthropometric data of Ferrari car company employers’ children were collected, analyzed, and compared. Moreover, at the visit of November 2020, performed after the first wave of the pandemic with the most rigorous lockdown rules in Italy, a questionnaire on nutritional and lifestyle habits was administered. We evaluated 307 children (163 M, 10.1 ± 2.3 mean aged in 2019). A significant increase in BMI percentile in 2020 (65.2) compared to 2019 (49.2) was observed; it was confirmed, albeit slightly decreased, in 2021 (64.5). About one-third of participants reported an increase in consumption of fatty condiments and more than half report an increase in consumption of junk food. Levels of physical activity were still high during the COVID-19 lockdown, while sleeping time was significantly reduced. Our findings alert us to the importance of carefully monitoring eating behaviors in young to avoid the adoption of unhealthy food habits and prevent childhood obesity, especially during the period of COVID-19 lockdown.

ObjectiveRecent data suggest that cerebral amyloid angiopathy (CAA) causes haemorrhagic lesions in cerebellar cortex as well as subcortical cerebral atrophy. However, the potential effect of CAA on cerebellar tissue loss and its clinical implications have not been investigated.MethodsOur study included 70 non-demented patients with probable CAA, 70 age-matched healthy controls (HCs) and 70 age-matched patients with Alzheimer’s disease (AD). The cerebellum was segmented into percent of cerebellar subcortical volume (pCbll-ScV) and percent of cerebellar cortical volume (pCbll-CV) represented as percent (p) of estimated total intracranial volume. We compared pCbll-ScV and pCbll-CV between patients with CAA, HCs and those with AD. Gait velocity (metres/second) was used to investigate gait function in patients with CAA.ResultsPatients with CAA had significantly lower pCbll-ScV compared with both HC (1.49±0.1 vs 1.73±0.2, p<0.001) and AD (1.49±0.1 vs 1.66 ± 0.24, p<0.001) and lower pCbll-CV compared with HCs (6.03±0.5 vs 6.23±0.6, p=0.028). Diagnosis of CAA was independently associated with lower pCbll-ScV compared with HCs (p<0.001) and patients with AD (p<0.001) in separate linear regression models adjusted for age, sex and presence of hypertension. Lower pCbll-ScV was independently associated with worse gait velocity (β=0.736, 95% CI 0.28 to 1.19, p=0.002) in a stepwise linear regression analysis including pCbll-CV along with other relevant variables.InterpretationPatients with CAA show more subcortical cerebellar atrophy than HC or patients with AD and more cortical cerebellar atrophy than HCs. Reduced pCbll-ScV correlated with lower gait velocity in regression models including other relevant variables. Overall, this study suggests that CAA causes cerebellar injury, which might contribute to gait disturbance.

Background: Child musculoskeletal (MSK) diseases are common and, even if often benign, sometimes can lead to significant impairment in the future health of children. Italian pre-participation evaluation (PPE), performed by a sports medicine physician, allows for the screening of a wide range of children every year. Therefore, this study aims to evaluate the feasibility and the acceptability of pGALS (pediatric Gait, Arms, Legs and Spine) screening, a simple pediatric MSK screening examination, when performed as part of a routine PPE. Methods: Consecutive school-aged children attending a sports medicine screening program were assessed with the addition of pGALS to the routine clinical examination. Practicability (time taken) and patient acceptability (discomfort caused) were recorded. Results: 654 children (326 male, mean age 8.9 years) were evaluated through pGALS. The average time taken was 4.26 min (range 1.9–7.3 min). Acceptability of pGALS was deemed high: time taken was “adequate” (97% of parents) and caused little or no discomfort (94% of children). Abnormal MSK findings were common. Conclusions: pGALS is a practical and acceptable tool to perform in sports medicine PPE, even if performed by a non-expert in MSK medicine. Although common, abnormal MSK findings need to be interpreted in the global clinical context and assessment.

Background
Cognitive impairment and depressive symptoms are highly prevalent after Intracerebral Hemorrhage (ICH). We leveraged Latent Profile Analysis (LPA) to identify profiles for cognitive decline and depression onset after ICH. We also investigated differences in clinical, genetic and neuroimaging characteristics across patients’ profiles.
Methods
We analyzed data from the ICH study conducted at Massachusetts General Hospital between January 1998 and December 2019. We collected information from electronical health records, follow-up interviews, CT and MRI imaging, and
APOE
genotype. We conducted LPA and multinomial logistic regression analyses to: 1) identify distinct profiles for cognitive decline and depression onset after ICH; 2) identify clinical, neuroimaging and genetic factors predicting individuals’ likelihood to express a specific profile.
Results
We followed 784 ICH survivors for a median of 45.8 months. We identified four distinct profiles in cognitive and depressive symptoms after ICH: low depression and dementia risk, early-onset depression and dementia, late-onset depression and dementia, high depression with low dementia risk. Cerebral small vessel disease severity and
APOE
genotype were specifically associated with the late-onset profile (both
p <
0.05). Acute hematoma characteristics (size, intraventricular extension) and functional disability were specifically associated with the early-onset profile (all
p <
0.05).
Conclusion
We identified four distinct profiles for cognitive and depressive symptoms after ICH, each displaying specific associations with individual patients’ clinical, genetic and neuroimaging data. These associations reflect separate biological mechanisms influencing dementia and depression risk after ICH. Our findings support employing LPA in future ICH studies, and is likely applicable to stroke survivors at large.

Carriers of
APOE ɛ2 and ɛ4 have an increased risk of intracerebral haemorrhage (ICH) in lobar regions, presumably because of the effects of these gene variants on risk of cerebral amyloid angiopathy. We aimed to assess whether these variants also associate with severity of ICH, in terms of haematoma volume at presentation and subsequent outcome.
We investigated the association of
APOE ɛ2 and ɛ4 with ICH volume and outcomes in patients with primary ICH in three phases: a discovery phase of 865 individuals of European ancestry from the Genetics of Cerebral Hemorrhage on Anticoagulation study, and replication phases of 946 Europeans (replication 1) and 214 African-Americans (replication 2) from an additional six studies. We also assessed the association of
APOE variants with ICH volume and outcomes in meta-analyses of results from all three phases, and the association of
APOE ɛ4 with mortality in a further meta-analysis including data from previous reports. Admission ICH volume was quantified on CT scan. We assessed functional outcome (modified Rankin scale score 3–6) and mortality at 90 days. We used linear regression to establish the effect of genotype on haematoma volume and logistic regression to assess the effect on outcome from ICH.
For patients with lobar ICH, carriers of the
APOE ɛ2 allele had larger ICH volumes than did non-carriers in the discovery phase (p=2·5×10
−5), in both replication phases (p=0·008 in Europeans and p=0·016 in African-Americans), and in the meta-analysis (p=3·2×10
−8). In the meta-analysis, each copy of
APOE ɛ2 increased haematoma size by a mean of 5·3 mL (95% CI 4·7–5·9; p=0·004). Carriers of
APOE ɛ2 had increased mortality (odds ratio [OR] 1·50, 95% CI 1·23–1·82; p=2·45×10
−5) and poorer functional outcomes (modified Rankin scale score 3–6; 1·52, 1·25–1·85; p=1·74×10
−5) compared with non-carriers after lobar ICH.
APOE ɛ4 was not associated with lobar ICH volume, functional outcome, or mortality in the discovery phase, replication phases, or meta-analysis of these three phases; in our further meta-analysis of 2194 patients, this variant did not increase risk of mortality (1·08, 0·86–1·36; p=0·52).
APOE allele variants were not associated with deep ICH volume, functional outcome, or mortality.
Vasculopathic changes associated with the
APOE ɛ2 allele might have a role in the severity and clinical course of lobar ICH. Screening of patients who have ICH to identify the ɛ2 variant might allow identification of those at increased risk of mortality and poor functional outcomes.
