Diabetes is a common chronic disease. Untreated diabetes may lead to complications such as nephropathy, neuropathy, retinopathy, and macroangiopathies. The main goal in treating diabetes is to limit the development of vascular complications. The FGF (fibroblast growth factor) family, with its potential as a biomarker for diabetic complications, offers a promising avenue for future research and treatment. The study aimed to analyze and compare the concentrations of selected fibroblast growth factors, FGF-2, FGF-19, FGF-22, and FGF-23, in the plasma of patients with type 1 and type 2 diabetes with those of the control group. The study group consisted of 73 patients, including 33 people with type 1 diabetes (18 M and 15 W) aged 18 to 68 years and 40 with type 2 diabetes (20 M and 20 W) aged 25 to 90. The control group consisted of 41 healthy individuals (23 men and 18 women) aged 21 to 56. The FGF-2, FGF-19, FGF-22, and FGF-23 concentrations were measured using ELISA. The study observed a significant relationship between the levels of FGF19 and FGF22 in the serum of patients with type 1 and type 2 diabetes, as well as in the control group (p < 0.001; p < 0.001). Statistical analysis revealed a significant relationship between FGF-2 and FGF-22 concentrations and hypertension (p = 0.03; p = 0.01). A statistically significant difference was also found between the concentrations of FGF-19 and FGF-22 (p = 0.001; p < 0.001) in the serum of people with normal weight and people with overweight and obesity. A significant correlation was also observed between the concentrations of FGF-22 and FGF-23 and arthritis (p = 0.01; p = 0.02). FGF-2, FGF-19, FGF-22, and FGF-23 likely significantly impact diabetes and its complications. In the future, they could serve as biomarkers for diabetic complications, aiding in diagnosis, patient monitoring, and even predicting potential complications for individuals. However, more research in this area is necessary. Full article

Background/Objectives: To develop and validate deep learning-based models for detecting significant steno-occlusion (SSO)—defined as luminal narrowing greater than 50%—of the femoropopliteal arteries using maximum intensity projection (MIP) images from lower extremity CT angiography (CTA). Methods: This retrospective study utilized MIP images of lower extremity CTA performed between January 2021 and December 2023 for internal model development. Deep learning-based models were developed sequentially to diagnose SSO: screening with single anteroposterior image, followed by four-segment rotational analysis that divided each femoropopliteal artery into four segments and incorporated multi-angle images. Given the cropped images and the shape of stenosis, models were trained to classify the presence of SSO. A temporal validation dataset comprised MIP images from lower extremity CTA performed between January and June 2024. Results: In total, 56,496 segment images from 642 patients (mean age: 68.2 ± 13.5 years; 472 men) were included in the internal dataset. In the single-image analysis, RDNet achieved the highest mean AUC of 0.886 for SSO detection. In the four-segment rotational analysis, RDNet also demonstrated the highest mean AUC, reaching 0.964 in both half-set and full-set approaches. While RDNet recorded the highest mean AUC, all other models showed improved AUCs as the number of input images increased (p < 0.05). In the temporal validation dataset, RDNet again achieved the highest mean AUC (0.959) in the half-set analysis. Conclusions: The deep learning-based model, particularly RDNet, demonstrated excellent performance in detecting SSO of peripheral arteries on MIP images from lower extremity CTA. Full article

Our study examined the associations between overall cardiovascular health (CVH) and the risk of disability in older adults over 16 years of follow-up. Data from the InCHIANTI study were used and included 928 participants aged 65 years and older. Overall CVH was measured using the “Life’s Essential 8” (LE8) metric. Disability status was assessed by the Activities of Daily Living (ADL) and the Instrumental Activities of Daily Living (IADL). Higher overall LE8 score at baseline was associated with lower risks of having the first ADL among males (hazard ratio [HR] = 0.66, p = 0.001) and IADL disability event (HR = 0.89, p = 0.016) using the Cox proportional hazards model. Higher LE8 scores were also associated with ADL (odds ratio [OR] (females) = 0.80, p = 0.034; OR (males) = 0.55, p < 0.001) and IADL worsening (OR = 0.72, p < 0.001) using Generalized Estimating Equation models. Among older adults, better CVH assessed by the LE8 metric was associated with lower risk of ADL and IADL disabilities and their worsening over time. These findings underscore the importance of promoting CVH as a key strategy to support healthy aging and reduce disability burden. Public health interventions that target CVH components may be effective in preserving functional independence among older populations. Full article

Academic stress arises from students facing academic demands and is linked to various academic and psychological factors. However, research has yet to explore its potential correlations with somatization, overall health issues, studying strategies, academic procrastination, academic performance, and intelligence scores. The objective of this study was to determine the potential correlations between such variables with academic stress in a sample of health sciences university students. University students of different bachelor’s programs were invited to participate; they fulfilled an electronic questionnaire with personal and psychological variables, including academic stress, and performed an intelligence test, which measures verbal and non-verbal intelligence. Finally, their academic achievement was measured with the grade point average (GPA). A total of 437 students were included, of which 296 (67.7%) were women, with a mean age of 20.36 ± 2.61 years old. Academic stress was higher in women than in men and showed moderate positive correlations with anxiety, depression, and somatization and a low positive correlation with the sum of diseases. It also showed a low negative correlation with sleep quality. In addition, academic stress correlated negatively with self-motivation, emotion perception, and emotion management as well as with active coping, positive relations with others, and the studying strategies (self-regulation, effort regulation, critical thinking, and time and study environment). We also observed a low positive correlation between academic stress and academic procrastination, which was higher in women than in men. No correlations were found with GPA or intelligence scores. In conclusion, academic stress was positively correlated with somatization, depression, anxiety, the sum of diseases, and academic procrastination; it was negatively correlated with emotional intelligence (mainly self-motivation), active coping, and specific studying strategies.

Introduction: Patients with obstructive sleep apnea (OSA) and asthma share common symptoms and risk factors. Aim: The aim of this study is to evaluate the clinical characteristics of patients with OSA and asthma and assess the impact of CPAP treatment on asthma control and exacerbations. Methods: Consecutive patients diagnosed with concomitant OSA and asthma were enrolled in the study. Data on patients’ characteristics, respiratory function during wakefulness, and polysomnography were recorded. Additionally, asthma control and exacerbation history were assessed the year before and after initiation of CPAP therapy. Results: The cohort included 102 patients (53 men and 49 women; mean age 56.5 ± 12.8 years). The severity of OSA was classified as severe in 49%, moderate in 27.5%, and mild in 23.5% of patients. The most common comorbidities were arterial hypertension (66.7%) and dyslipidemia (52%). Before CPAP initiation, most patients (55.9%) had moderate asthma control (ACT score 17.4 ± 0.9). Following CPAP treatment, the ACT score was improved (p < 0.001) and asthma exacerbations were significantly reduced (p = 0.002). Moreover, the Asthma Control Test (ACT) score was negatively correlated with BMI (r = −0.209, p = 0.035), AHI (r = −0.426, p < 0.001), oxygen desaturation index (r = −0.466, p < 0.001), and percentage of sleep time with oxygen saturation <90% (T < 90%) (r = −0.228, p = 0.021). Also, patients who experienced exacerbations (44/102) had higher AHI (p = 0.022) and more severe nocturnal hypoxia (T < 90%, p = 0.016). Conclusions: Asthma control is associated with OSA severity and BMI, while CPAP therapy seems to improve asthma control and reduces exacerbations in patients with concomitant OSA and asthma.

Background: Neuroendocrine neoplasms (NENs) are a diverse group of malignancies in which somatostatin receptor expression can be crucial in guiding therapy. We aimed to evaluate the effectiveness of [^99mTc]Tc-EDDA/HYNIC-TOC SPECT/CT in differentiating neuroendocrine tumor histology, selecting candidates for radioligand therapy, and identifying correlations between somatostatin receptor expression and non-imaging parameters in metastatic NENs. Methods: This retrospective study included 65 patients (29 women, 36 men, mean age 61) with metastatic neuroendocrine neoplasms confirmed by histology, follow-up, or imaging, comprising 14 poorly differentiated carcinomas and 51 well-differentiated tumors. Somatostatin receptor SPECT/CT results were assessed visually and semiquantitatively, with mathematical models incorporating histological, oncological, immunohistochemical, and laboratory parameters, followed by biostatistical analysis. Results: Of 392 lesions evaluated, the majority were metastases in the liver, lymph nodes, and bones. Mathematical models estimated somatostatin receptor expression accurately (70–83%) based on clinical parameters alone. Key factors included tumor origin, oncological treatments, and the immunohistochemical marker CK7. Associations were found between age, grade, disease extent, and markers (CEA, CA19-9, AFP). Conclusions: Our findings suggest that [^99mTc]Tc-EDDA/HYNIC-TOC SPECT/CT effectively evaluates somatostatin receptor expression in NENs. Certain immunohistochemical and laboratory parameters, beyond recognized factors, show potential prognostic value, supporting individualized treatment strategies. Full article

Objectives: The goal of this longitudinal study was to explore how gastrointestinal-symptom distress and benefit finding together influence health-related quality of life (HRQOL) over time in colorectal cancer (CRC) survivors. Colorectal cancer (CRC) survivorship may differ from other cancer types due to the persistent burden of gastrointestinal symptoms. The highly visible and socially sensitive nature of these sequelae may influence the trajectory of benefit finding compared with other cancers. Specifically, we explored whether increases in symptom distress predicted declines in physical and mental HRQOL whether benefit finding was directly related to or buffered the negative impact of symptom distress on HRQOL. Methods: Participants were 73 Taiwanese women and men who underwent surgery for CRC. Using a three-time-point, multilevel framework, participants were assessed at 1, 3, and 6 months after surgery. Hierarchical linear modeling was used to investigate whether gastrointestinal-symptom distress and benefit finding covary over time with HRQOL. Results: The results indicated that increases in gastrointestinal-symptom distress were linked to declines in both physical and mental HRQOL. Benefit finding had no direct association with HRQOL but significantly moderated the symptom-HRQOL relationship, weakening the negative impact of symptom distress among those with higher benefit finding. Conclusions: Rises in a CRC survivor’s gastrointestinal-symptom distress went hand-in-hand with drops in both physical and mental HRQOL. This study adds to the literature in that benefit finding has a favorable effect on cancer adjustment when patients face higher symptom distress after the surgery and treatment. Further implications on possible mechanisms were discussed. Full article

Background: Metabolic syndrome is a multifaceted condition involving lipid and carbohydrate metabolism disorders and hypertension, increasing the risk of cardiovascular disease and type 2 diabetes. Accurate diagnosis and prevention require an interdisciplinary approach that includes both traditional lab tests and modern, non-invasive health assessments. Methods: This study aimed to evaluate metabolic health in adults from the Małopolska Voivodeship by analyzing the relationships between obesity indicators (BMI, waist circumference) and anthropometric, blood, and salivary biomarkers. Sixty-three participants (36 women, 27 men) aged 40–71 underwent body composition analysis (InBody 770), anthropometric measurements, and biochemical tests of blood and saliva. Assessed parameters included body composition (BMI, BFM, FFM, SMM, PBF, VFA, PA), blood pressure, blood biomarkers (glucose, TG, LDL, HDL, HbA1c, insulin, cortisol), and salivary markers (FRAP, DPPH, urea, amylase activity, protein content, pH, buffering capacity). Results: The results showed a strong correlation between body composition and biochemical markers, but the results of the analyzed salivary biomarkers were inconclusive and, in some cases, contradictory to the findings of other authors. Conclusions: Fat mass, cell integrity, and diastolic pressure were key determinants of waist circumference. Our research confirms the validity of using combined diagnostics, bioimpedance, and blood analysis for a comprehensive assessment of metabolic health and indicates the direction for further research using salivary biomarkers. A holistic approach improves risk assessment and strengthens preventive and therapeutic strategies. However, our pilot study showed that the research requires a larger sample size, especially in order to draw representative conclusions regarding salivary biomarkers and their relationship to metabolic health.

Background/Objectives: Tinnitus often occurs alongside the emotional symptoms of anxiety and depression. The Ginkgo biloba extract EGb 761^® was shown to be effective in reducing neuropsychiatric symptoms in elderly patients with both dementia and tinnitus, exerting direct effects on tinnitus severity and indirect effects mediated by improvement of anxiety, depression, and cognition. Whether the extent of the effects is influenced by the patient’s sex has not yet been investigated. We performed a conditional process analysis to evaluate this question. Methods: We analyzed the moderating role of sex on the direct and indirect effects of EGb 761^® on tinnitus severity using a first- and second-stage conditional process model. Results: Indirect effects of EGb 761^® on tinnitus severity mediated by improved cognition, anxiety, and depression did not differ between women and men (p > 0.05; all 95% bootstrap confidence intervals overlapped with zero). Moreover, direct treatment effects of EGb 761^® on tinnitus severity were statistically significant for both sexes (women, p < 0.0001; men, p = 0.0279). Conclusions: Beneficial effects of Ginkgo biloba extract EGb 761^® in dementia patients with tinnitus are likely to be unaffected by the patient’s sex. Further research into the influence of patient characteristics on the outcome of tinnitus drug treatment is encouraged. Full article

Adult cyberbullying remains understudied in Spain, where research has largely centered on adolescents. This study quantified the prevalence and behavioral profile of cyberbullying perpetration in Madrid adults and examined whether Fear of Missing Out (FoMO) and Critical Thinking (CT) differentiate aggressors from non-aggressors. A cross-sectional, community-based survey of 821 residents (51% women; M = 38.2 years, SD = 11.9) was conducted between July 2024 and January 2025. Participants completed a twelve-item dichotomous checklist of cyberbullying perpetration, a 10-item FoMO scale, and an 11-item CT scale. Group contrasts were analyzed with independent sample t-tests and effect sizes (Cohen’s d). Results indicated that nine of the twelve behaviors were endorsed by fewer than 7% of respondents; the most common offense was sending mocking or insulting messages (13.8%). Men and adults aged 18–33 accounted for most of the aggression across indicators. Perpetrators reported significantly higher FoMO and marginally lower CT than non-perpetrators. FoMO differences were largest for message forwarding, threats, and public humiliation. CT deficits were most pronounced for covert tactics such as impersonation and rumor-spreading, whereas threat perpetrators displayed CT scores comparable to non-aggressors. To conclude, interventions that combine FoMO-reduction strategies with ethically grounded CT training may be necessary to curb adult cyberbullying. Full article

Background: Brain computed tomography (CT) is the primary imaging modality for patients with acute neurological complaints in emergency departments, despite having a low diagnostic yield for many conditions. This study aimed to assess the common indications for brain CT, evaluate the prevalence of acute pathologies, and explore whether certain patient groups may be overexposed to unnecessary scans, impacting both patient safety and healthcare costs. Methods: We conducted a retrospective review of brain CT requests from the General Emergency Department in a single center over a one-month period. We recorded patient demographics (sex, age), scan indications, presence of focal neurological symptoms, acute pathology on CT, and final diagnoses. Descriptive statistics, including means ± SEM, were calculated using GraphPad Prism version 10.4.1. Results: A total of 584 brain CT scans were requested, of which 532 (91.1%) were normal, and 52 (8.9%) showed acute pathology. The age of all included patients were 70.8 ± 0.7 years with women (n = 304, 52.1%) being 71.9 ± 1.0 years old and men (n = 280, 47.9%) 69.7 ± 1.0 years old (p > 0.1). The most common indication for CT was head trauma (265, 45.4%) followed by ischemic stroke (130, 22.3%). The most frequent pathologies were ischemic stroke (2.7%), subdural hematoma (1.7%), and other traumatic bleeds (1.7%). Of the 52 patients with acute pathology, 42 (80.8%) exhibited focal neurological deficits. Conclusions: 91.1% of the brain CT scans in the emergency department were normal and did not lead to further intervention. While this may indicate a low diagnostic yield in certain patient groups—particularly those presenting with mild or nonspecific neurological symptoms—it does not alone confirm overuse. These findings highlight the importance of careful clinical evaluation to optimize imaging decisions. Reducing potentially unnecessary brain CT scans could lower healthcare costs and minimize radiation exposure, but the health-economic impact depends on balancing the savings with the potential costs of missing critical diagnoses and the associated societal consequences.

Background: Research shows that experiences of sexual violence and the use of substances hurt mental health, predisposing individuals to the development of psychological symptoms of somatization, depression, and anxiety. Objective: The main objective of this study is to assess substance use, sexual violence, and psychological symptoms (BSI-18) in a community sample of Portuguese college students. Participants: 459 college students aged 18 to 50 years participated in this study (mean = 21.55; SD = 3.15). Methods: A survey was created online and disseminated via mailing lists and social networks, and the measurement instruments used were an informed consent form, a sociodemographic questionnaire, the Brief Symptom Inventory-18 (BSI-18), a Sexual Violence Questionnaire, and a Substance Use Questionnaire. Results: We found that men consume more substances, but women report more sexual victimization and psychological symptoms. Non-heterosexuals report significantly more sexual violence experiences and higher substance consumption and psychological symptoms than heterosexuals. Sexual victimization showed strong correlations with both substance use and psychological symptoms, while only some substances correlated with psychological symptoms. Age, gender, sexual orientation, sexual violence, and the substance “Hashish/Marijuana” were shown to be significant and strong predictors of psychological symptoms. Conclusions: As shown in previous studies, sexual and gender minorities are more at risk of experiencing sexual victimization and are more prone to consuming substances and developing psychological symptoms, except for men, who tend to consume more substances. Sexual violence and psychological symptoms are highly correlated, while the relation between substance use and psychological symptoms is not entirely clear. Our findings highlight the need for stronger educational and clinical interventions and increased mental health resources, with training on topics involving sexual violence, substance use, and addressing the specific challenges faced by minority groups, to create safer, inclusive, and more supportive Portuguese universities.

This article reports the findings of an ethnographic and historical study into an ultras group called Melbourne Croatia Fans (MCF), a group of mostly Croatian–Australian young men in their twenties who support Melbourne Knights (formerly known as Melbourne Croatia) in the second-tier Victorian Premier League competition. The aim is to explore identity formation and negotiation, and how identity formation informs relations with outsider groups. The interviews with the football club president, football club secretary, two MCF leaders, and the participant observation date back to the 2010–12 period. The supporters perceive that the club has fallen on hard times for reasons not of their own making. They participated in the former National Soccer League (NSL) (1977–2004) from 1984 to 2004, which was the first-ever national competition in Australia to involve club rather than state teams. However, the club was effectively banned from the new A-League (2005–present), which began based on a private-equity ownership model and a one-team-one-city concept. Despite this, the club can play in the annual knockout competition, the Australia Cup (formerly the FFA Cup), that features both A-League and lower-league teams. We observe here a group of young Croatian–Australian men, part of the Diaspora of Croatians that left the country, mostly in the communist era and afterwards, who aim to construct workable hybrid identities for themselves in an Anglo-majority nation on the other side of the world. They fight on two fronts—against an Anglo, corporate-style administration that effectively bans their club for reasons of ethnicity from the new national league, and against the Serbian youth who often live in the who live in adjacent or nearby suburbs and follow Serbian-origin clubs.

Background: Alterations in peripheral red blood cell (RBC) indices have been proposed as potential biomarkers for Parkinson’s disease (PD), but their diagnostic utility and relation to clinical features remain uncertain. Methods: We conducted a pilot case–control study involving 70 PD patients and 122 controls from two neurology centers in Mexico. Standardized hematology analyses provided RBC indices, and neuropsychiatric assessments included the Hamilton Depression Rating Scale (HAM-D) and Mini-Mental State Examination (MMSE). Associations between RBC indices and PD were tested using multivariable logistic regression adjusted for age, sex, and smoking. Diagnostic performance was evaluated by receiver operating characteristic (ROC) curve analysis. Subgroup analyses stratified PD patients by age at onset, disease duration, and Hoehn and Yahr (HY) stage. Results: PD patients exhibited significantly higher mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) than controls. Elevated MCHC was independently associated with PD (OR = 1.68, 95% CI 1.35–2.09; p < 0.001). Sex-stratified models confirmed consistent associations in women (OR = 1.57) and men (OR = 1.79). ROC analysis demonstrated fair diagnostic accuracy for MCHC (AUC 0.72, 95% CI 0.65–0.80; cutoff 33.9 g/dL, sensitivity 62.9%, specificity 72.1%). Sex-specific thresholds improved sensitivity in women (90.6%) and specificity in men (74.6%). Within the PD group, MCHC did not differ by HY stage or disease duration, and showed no correlation with UPDRS, HAM-D, or MMSE scores. Early-onset cases (<50 years) showed numerically higher MCHC, though numbers were limited. Conclusions: This pilot study confirms that an elevated MCHC is independently associated with PD, a finding consistent across both sexes and independent of disease severity. MCHC demonstrates fair diagnostic performance, supporting its potential as a low-cost, accessible biomarker. Larger longitudinal studies integrating RBC indices with inflammatory and iron-regulatory markers are warranted to establish their role in the diagnosis and differential diagnosis of PD. Elevated MCHC was associated with PD, and an MCHC-based index (cutoff 33.9 g/dL; AUC 0.72, sensitivity 62.9%, specificity 72.1%) showed potential as a simple diagnostic marker. Full article

Primary retroperitoneal mucinous cystadenocarcinoma (PRMC) is an uncommon malignant neoplasm with few reported cases, particularly among male patients. Currently, only nine documented cases have been reported worldwide, including the present case. The present case report describes the incidental detection of PRMC in an 86-year-old male patient. Despite being offered surgical intervention, the patient initially opted against treatment. Consequently, follow-up imaging examinations were performed for 3 subsequent years. The tumor, initially measuring 31 × 32 × 31 mm, gradually increased to 58 × 60 × 59 mm. Subsequently, the patient underwent laparoscopic retroperitoneal tumor resection. Histopathological examination revealed adenocarcinoma characterized by intestinal differentiation. The patient has exhibited no evidence of disease for 1 year postoperatively. The present case is noteworthy, as this disease rarely occurs in men, thereby offering significant potential for educational and scientific contributions. Notably, the patient’s age, longitudinal observation of tumor progression through imaging over a period of 3 years, and complete surgical excision of the tumor are salient features of this case. These findings may prove useful in the diagnosis and treatment strategy for male patients with PRMC. Full article
