RESUMO

We report a case of a 63-year-old woman diagnosed with vascular Ehlers-Danlos syndrome (vEDS) who survived two prophylactic surgeries for the dilatation of a thoracoabdominal aortic aneurysm. She initially developed acute type B aortic dissection at the age of 44 years. Five years later, her dissected descending aorta was enlarged to 54 mm; thus, the descending aorta was replaced as the first surgery. Fortunately, the intra- and post-operative courses were uneventful. Fourteen years post her first surgery, the dissected thoracoabdominal aorta distal to the graft expanded to 53 mm; however, no anastomotic leakage was observed. Genetic testing revealed a COL3A1 abnormality, confirming the diagnosis of vEDS. Thoracoabdominal aorta replacement using deep hypothermia circulatory arrest was performed because of the high risk of aortic aneurysm rupture. The second surgery was performed without complications, and no complications were observed 13 months post-surgery. The major reason for a successful surgery in this patient was the relatively low vascular fragility associated with vEDS. This case demonstrates that there may be considerable individual differences in vascular fragility in patients with vEDS. Thus, surgical repair, along with endovascular therapy, might still be a beneficial option for patients with vEDS having large aortic aneurysms and a high risk of rupture. Learning objective: Prophylactic surgery for vascular lesions in Ehlers-Danlos syndrome (vEDS) is generally not recommended because of its high vascular fragility. However, if a patient with vEDS has an aortic aneurysm that is at a very high risk of rupture, aggressive treatment is a plausible option as there may be considerable individual differences in vascular fragility among patients with vEDS.

RESUMO

BACKGROUND: Few studies have reported an association between an increased risk of acquiring cancers and survival in patients with 4q deletion syndrome. This study presents a rare association between chromosome 4q abnormalities and fallopian tube high-grade serous carcinoma (HGSC) in a young woman. CASE SUMMARY: A 35-year-old woman presented with acute dull abdominal pain and a known chromosomal abnormality involving 4q13.3 duplication and 4q23q24 deletion. Upon arrival at the emergency room, her abdomen appeared ovoid and distended with palpable shifting dullness. Ascites were identified through abdominal ultrasound, and computed tomography revealed an omentum cake and an enlarged bilateral adnexa. Blood tests showed elevated CA-125 levels. Paracentesis was conducted, and immunohistochemistry indicated that the cancer cells favored an ovarian origin, making us suspect ovarian cancer. The patient underwent debulking surgery, which led to a diagnosis of stage IIIC HGSC of the fallopian tube. Subsequently, the patient received adjuvant chemotherapy with carboplatin and paclitaxel, resulting in stable current condition. CONCLUSION: This study demonstrates a rare correlation between a chromosome 4q abnormality and HGSC. UBE2D3 may affect crucial cancer-related pathways, including P53, BRCA, cyclin D, and tyrosine kinase receptors, thereby possibly contributing to cancer development. In addition, ADH1 and DDIT4 may be potential influencers of both carcinogenic and therapeutic responses.

RESUMO

This study examined the effects of exercise and detraining at a young age on fat accumulation in various organs. Four-week-old male Otsuka Long-Evans Tokushima Fatty (OLETF) rats were assigned to either the non-exercise sedentary (OLETF Sed) or exercise groups. The exercise group was subdivided into two groups: exercise between 4 and 12 weeks of age (OLETF Ex) and exercise between 4 and 6 weeks of age followed by non-exercise between 6 and 12 weeks of age (OLETF DT). Body weight was significantly lower in the OLETF Ex group than in the OLETF Sed group at 12 weeks of age. Fat accumulation in the epididymal white adipose tissue, liver, and brown adipose tissue was suppressed in the OLETF Ex group. During the exercise period, body weight and food intake in the OLETF DT group were significantly lower than those in the OLETF Sed group. However, food intake was significantly higher in the OLETF DT group than in the OLETF Sed group after exercise cessation, resulting in extreme obesity with fatty liver and brown adipose tissue whitening. Detraining after early-onset exercise promotes hyperphagia, causing extreme obesity. Overeating should be avoided during detraining periods in cases of exercise cessation at a young age.

RESUMO

Early-onset breast cancer (EoBC), defined by a diagnosis <40 years of age, is associated with poor prognosis. This study investigated the mutational landscape of non-metastatic EoBC and the prognostic relevance of mutational signatures using 100 tumour samples from Alberta, Canada. The MutationalPatterns package in R/Bioconductor was used to extract de novo single-base substitution (SBS) and insertion-deletion (indel) mutational signatures and to fit COSMIC SBS and indel signatures. We assessed associations between these signatures and clinical characteristics of disease, in addition to recurrence-free (RFS) and overall survival (OS). Five SBS and two indel signatures were extracted. The SBS13-like signature had higher relative contributions in the HER2-enriched subtype. Patients with higher than median contribution tended to have better RFS after adjustment for other prognostic factors (HR = 0.29; 95% CI: 0.08-1.06). An unsupervised clustering algorithm based on absolute contribution revealed three clusters of fitted COSMIC SBS signatures, but cluster membership was not associated with clinical variables or survival outcomes. The results of this exploratory study reveal various SBS and indel signatures may be associated with clinical features of disease and prognosis. Future studies with larger samples are required to better understand the mechanistic underpinnings of disease progression and treatment response in EoBC.

RESUMO

BACKGROUND/AIM: Patients' age may influence the response to chemotherapy and the clinical course of breast carcinoma. This study aimed to compare the spatial transcriptomic profiles between younger (≤50 years) and older (>50 years) patients with hormone receptor (HR)-positive breast carcinoma. PATIENTS AND METHODS: Seven cases of breast carcinoma were included. We performed digital spatial profiling and bioinformatic analysis to investigate the spatial transcriptomes of the epithelial and stromal compartments. RESULTS: In the epithelial compartment of three young-age breast carcinoma (YABC) cases, we found 21 up-regulated and 7 down-regulated genes. The top two most up-regulated genes were serpin peptidase inhibitor clade A member 1 and serine protease. The gene ontology enrichment analysis revealed a significant up-regulation of genes defining ribosomal structures and functions in YABCs. The gene set enrichment analysis revealed that gene sets defining early and late responses to estrogen, response to interferon-α, and tumor necrosis factor-α signaling were significantly enriched in YABCs. CONCLUSION: We described for the first time the age-related differences in spatially resolved transcriptomic profiles and up-regulated transcriptional pathways of HR-positive breast carcinoma. Our observations highlight the critical need for age-specific treatment strategies for breast carcinoma management.

RESUMO

BACKGROUND: Developing countries have a significantly higher incidence of breast cancer in patients younger than 40 years as compared to developed countries. This study aimed to examine if young age at diagnosis is an independent prognostic factor for worse survival outcomes in breast cancer as well as the effect of age on Disease-free survival (DFS) and local recurrence free survival (LRFS) after adjusting for various tumor characteristics, local and systemic treatments. METHODS: This is a secondary analysis of prospective cohort of patients from two existing databases. We identified patients with breast cancer aged 40 years or less and we matched them to those older than 40 years. We also matched based on stage and molecular subtypes. In cohort 1, we matched at a ratio of 1:1, while in cohort 2 we matched at a ratio of 1:3. RESULTS: In cohort 1, Disease-free survival (DFS) at 5 years was significantly shorter for those younger than 40 years (75.6% and 92.7% respectively; p < 0.03). On multivariate analysis, only chemotherapy was found to be significant, while age was not found to be an independent predictor of prognosis. Local recurrence free survival at 5 years was similar between both age categories. Only hormonal therapy is a significant predictor for LRFS at 5 years. In the second cohort, DFS and LRFS at 3 years were similar between those younger and those older than 40 years. On multivariate analysis, no factor including age was found to be an independent predictor of prognosis. CONCLUSION: Data in the literature is controversial on the effect of young age on breast cancer prognosis. Our findings could not demonstrate that age is an independent prognostic factor in our population. There is a need for outcomes from larger, prospective series that have longer follow-ups and more data from our region.

RESUMO

Background: An evaluation of the persistence of symptoms following COVID-19 in economically active young and middle-aged adults is crucial due to its significant socioeconomic impact resulting from compromised work performance. Methods: A prospective, multicenter study at 12 South Korean hospitals from January to December 2022 involved telephone interviews along with validated questionnaires. Results: Among 696 participants with a median age of 32 and no prior diagnoses, 30% of participants experienced persistent fatigue, while 21.4% suffered from sleep disturbance at 6 months following infection. Additionally, approximately 25% of the participants exhibited depression that endured for up to 6 months. Symptomatic individuals at 3 months exhibited a significantly higher prevalence of persistent fatigue, sleep disturbances, and depression at 6 months compared to those who remained asymptomatic. Notably, sleep disturbance and persistent fatigue at 3 months emerged as significant independent predictors of the presence of depression at 6 months. Conclusions: Even among young and middle-aged healthy adults, prolonged fatigue, sleep disturbance, and depression exhibit a significant prevalence and persisted for up to 6 months. Therefore, implementing a workplace management protocol for these symptoms is essential to mitigate the socioeconomic burden caused by the impairment of work efficiency.

RESUMO

OBJECTIVE: Aim: To study the clinical anatomy of the pulmonary ligaments of young people. PATIENTS AND METHODS: Materials and Methods: The study was carried out when performing 28 autopsies of young people aged 25 to 44 years. Methods of dissection of chest organocomplexes, macro-microscopy, morphometry and planimetry, and statistical processing were used. The shape and topography of the pulmonary ligaments was assessed, their area, the localization of lymph nodes was examined. RESULTS: Results: The pulmonary ligament is an anatomical formation, which is formed as a result of a combination of leaves of the mediastinal pleura, which, covering the surfaces of the roots of the lungs, descend towards the diaphragm and are located between the mediastinal organs and the lungs. Pulmonary connections on both sides have a few edges: the inner, outer and lower free. The pulmonary ligaments with lower free edges do not pass to the diaphragmatic surface of the pleura, but only with inner ones, which are located on the right along the esophagus, and on the left along the aorta. Pulmonary ligaments on both sides pass into the mediastinal part of the pleura, covering the pericardium. CONCLUSION: Conclusions: There are individual differences between the shape and size of the right and left pulmonary ligaments in males and females. There is no significant difference between the sizes of the right and left pulmonary ligaments, but such dimensions as: the width, the angle of inclination and the ratio of their lower free edge to the lower edge of the lungs are not found in all cases.

RESUMO

Takayasu arteritis (TAK) is a rare large-vessel vasculitis of unknown etiology that leads to arterial wall thickening, stenosis, and occlusion, which may complicate cerebrovascular ischemic events. Ischemic stroke is a potentially devastating complication of TAK at a young age, but the occurrence is still rarely reported in Ethiopia. Although it occurs late in the course of the condition, it may be the initial presentation and suggest an unfavorable prognosis. Herein, we address the case of a 25-year-old woman who presented to a university hospital while on follow-up after 2 years of stroke with deterioration in clinical symptoms, absent brachial artery pulses, and unrecordable blood pressure in both arms. At the time of admission in 2021, the contrast brain computed tomography scan revealed an ischemic infarction in the right middle cerebral artery territory. However, the etiology of the stroke could not be defined at that time due to ambiguity in the clinical picture and the inability of clinicians to incorporate TAK into the differential diagnosis, resulting in a delay in the early diagnosis of the case. Two years later, in 2023, she underwent computed tomography angiography and was diagnosed to have TAK based on American College of Rheumatology criteria, with Numano type IIb angiographic extent of disease, ischemic stroke, and stage II systemic hypertension. The patient was treated by a field of experts. This case highlights the need to consider TAK in the differential diagnosis of stroke in young patients in the absence of traditional risk factors; appropriate tests should be performed to confirm or rule out this diagnosis, and management should be modified accordingly.

RESUMO

OBJECTIVE: To evaluate the main modifiable risk factors for ischemic stroke (IS) and features of the course in atherothrombotic, cardioembolic, and lacunar subtypes of IS in men aged 18-50 years. MATERIAL AND METHODS: The study included 125 men (the mean age was 42.6±5.3 years) who were admitted to the Vascular department before the COVID-19 pandemic and survived for the first 30 days after IS. Information on patients' baseline characteristics, traditional vascular risk factors, and lifestyle risk factors was systematically collected. Neuroimaging, ultrasound and laboratory tests were performed. RESULTS: Atherothrombotic subtype was identified in 60 patients, lacunar subtype in 46 patients and cardioembolic subtype in 19 patients. In the group as a whole, major risk factors included arterial hypertension (83.2%), dyslipidemia (50.4%), smoking (67.2%), alcohol consumption (29.6%), obesity (16.8%), heart rhythm disorders (12%), and diabetes mellitus (8%). CONCLUSION: The study revealed the main risk factors, the frequency of which differed depending on the stroke subtype and the age of the patients.

RESUMO

BACKGROUND: Patient-derived xenograft (PDX) models serve as a valuable tool for the preclinical evaluation of novel therapies. They closely replicate the genetic, phenotypic, and histopathological characteristics of primary breast tumors. Despite their promise, the rate of successful PDX engraftment is various in the literature. This study aimed to identify the key factors associated with successful PDX engraftment of primary breast cancer. METHODS: We integrated clinicopathological data with morphological attributes quantified using a trained artificial intelligence (AI) model to identify the principal factors affecting PDX engraftment. RESULTS: Multivariate logistic regression analyses demonstrated that several factors, including a high Ki-67 labeling index (Ki-67LI) (p < 0.001), younger age at diagnosis (p = 0.032), post neoadjuvant chemotherapy (NAC) (p = 0.006), higher histologic grade (p = 0.039), larger tumor size (p = 0.029), and AI-assessed higher intratumoral necrosis (p = 0.027) and intratumoral invasive carcinoma (p = 0.040) proportions, were significant factors for successful PDX engraftment (area under the curve [AUC] 0.905). In the NAC group, a higher Ki-67LI (p < 0.001), lower Miller-Payne grade (p < 0.001), and reduced proportion of intratumoral normal breast glands as assessed by AI (p = 0.06) collectively provided excellent prediction accuracy for successful PDX engraftment (AUC 0.89). CONCLUSIONS: We found that high Ki-67LI, younger age, post-NAC status, higher histologic grade, larger tumor size, and specific morphological attributes were significant factors for predicting successful PDX engraftment of primary breast cancer.

RESUMO

Background: Stress is a biological process in which exposure to stressors is associated with bad health effects, decreased ability of disease management, and a higher likelihood for disease-related complications and comorbidities. Stress has been considered the main factor in the etiology of many diseases such as diabetes mellitus, cardiac diseases, and body aches for centuries. Students meet many stressful situations such as the need for success, academic demands, homesickness, and lack of social support. Coping with stress can be a leading cause in preventing psychological distress and a serious illness. Methods: A correlational cross-sectional approach was applied to the current research. The research targeted all secondary school male students in Abha city. A multistage cluster sample was applied by selecting schools and students from the Directorate of Education in Abha. Self-administered questionnaire sheets were distributed to students in their classes. The questionnaire covered students' sociodemographic data such as age, grades, parents' education and work, living conditions, and comorbidities. Stressors to which the students were exposed were also enumerated with the degree of stress for each. Stress was assessed using the Holmes-Rahe Stress Inventory for youth. Coping skills were measured using the abbreviated version of the COPE Inventory. Results: The study included 324 students whose ages ranged from 15 to 20 years old with a mean age of 17 ± 0.9 years old. Approximately 33% of the students were in first grade; 44.4% of the students had no or minimal level of stress while major stress was recorded among 26.5% of the students. In total, 77.8% of the students had moderate coping and none had high coping ability. Conclusion: The study revealed that more than half of the students had significant levels of stress and one out of each four had major stress. The most common stressors were due to the school environment and future planning. Young age, low socioeconomic status, parents' separation, and having chronic health problems were the most important determinants of stress among the students.

RESUMO

Breast cancer in young (<40 years) is associated with a higher frequency of aggressive tumor types and poor prognosis. It remains unclear if there is an underlying age-related biology that contributes to the unfavorable outcome. We aim to investigate the relationship between age and breast cancer biology, with emphasis on proliferation. Clinico-pathologic information, immunohistochemical markers and follow-up data were obtained for all patients aged <50 (Bergen cohort-1; n = 355, not part of a breast screening program) and compared to previously obtained information on patients aged 50 to 69 years (Bergen cohort-2; n = 540), who participated in the Norwegian Breast Cancer Screening Program. Young breast cancer patients presented more aggressive tumor features such as hormone receptor negativity, HER2 positivity, lymph-node metastasis, the HER2-enriched and triple-negative subtypes and shorter survival. Age <40 was significantly associated with higher proliferation (by Ki67). Ki67 showed weaker prognostic value in young patients. We point to aggressive phenotypes and increased tumor cell proliferation in breast cancer of the young. Hence, tumors of young breast cancer patients may present unique biological features, also when accounting for screen/interval differences, that may open for new clinical opportunities, stratifying treatment by age.

RESUMO

BACKGROUND AND AIM: Breast cancer is the most frequently occurring malignant disease in women and remains the leading cause of cancer-related deaths among females worldwide. The aim of this study is to evaluate the imaging findings of breast cancer in women under the age of 40 and analyze their pathological patterns. METHOD: A retrospective study was conducted from 2013 to 2019, involving 120 patients below 40 years of age with pathologically confirmed primary epithelial breast cancers. The data were collected from the electronic records of a tertiary hospital in Riyadh, Saudi Arabia. Mammograms were performed for 115 patients, ultrasounds were conducted for all patients, and MRI scans were carried out for 47 patients. RESULTS: All radiological findings and clinical characteristics of the 120 cases were retrieved from our digital-based system. The majority of breast cancer patients (83.4%) were between 30 and 40 years old, and the most common clinical presentation was a mass (45.8%). Out of the 73 patients who underwent genetic tests, 32.9% tested positive for gene mutations. No statistically significant correlation was found between specific age groups and breast composition (P = 0.216), specific mammogram abnormalities such as masses (P = 0.262), or microcalcifications (P = 0.421). Ultrasonography was performed for all patients, with abnormalities detected in only one patient who was diagnosed with Paget's disease of the nipple. Masses, with or without parenchymal changes, were the predominant feature in 88.3% of cases. CONCLUSION: The imaging findings in breast cancer cases typically involve masses with suspicious features, irregular shape, and spiculated margins on mammograms, and irregular shape with microlobulated or angular margins on ultrasound. MRI features commonly include masses with irregular shape and heterogeneous enhancement. The luminal B subtype was identified as the most prevalent pathological feature, characterized by a high proliferative index (Ki-67%).

RESUMO

As the prevalence of juvenile-onset obesity rises globally, the multitude of related health consequences gain significant importance. In this context, obesity is associated with impaired cutaneous wound healing. In experimental settings, mice are the most frequently used model for investigating the effect of high-fat diet (HFD) chow on wound healing in wild-type or genetically manipulated animals, e.g., diabetic ob/ob and db/db mice. However, these studies have mainly been performed on adult animals. Thus, in the present study, we introduced a mouse model for a juvenile onset of obesity. We exposed 4-week-old mice to an investigational feeding period of 9 weeks with an HFD compared to a regular diet (RD). At a mouse age of 13 weeks, we performed excisional and incisional wounding and measured the healing rate. Wound healing was examined by serial photographs with daily wound size measurements of the excisional wounds. Histology from incisional wounds was performed to quantify granulation tissue (thickness, quality) and angiogenesis (number of blood vessels per mm2). The expression of extracellular matrix proteins (collagen types I/III/IV, fibronectin 1, elastin), inflammatory cytokines (MIF, MIF-2, IL-6, TNF-α), myofibroblast differentiation (α-SMA) and macrophage polarization (CD11c, CD301b) in the incisional wounds were evaluated by RT-qPCR and by immunohistochemistry. There was a marked delay of wound closure in the HFD group with a decrease in granulation tissue quality and thickness. Additionally, inflammatory cytokines (MIF, IL-6, TNF-α) were significantly up-regulated in HFD- when compared to RD-fed mice measured at day 3. By contrast, MIF-2 and blood vessel expression were significantly reduced in the HFD animals, starting at day 1. No significant changes were observed in macrophage polarization, collagen expression, and levels of TGF-ß1 and PDGF-A. Our findings support that an early exposition to HFD resulted in juvenile obesity in mice with impaired wound repair mechanisms, which may be used as a murine model for obesity-related studies in the future.

RESUMO

We report a case of a 25-year-old male with the traditional risk factor for coronary artery disease (CAD), such as frequent smoking, while the other risk factors such as familial history of CAD were denied and hypertension, obesity, diabetes mellitus, or coagulation factors were not found. Patient was admitted with anterior ST-elevation myocardial infarction. Coronary angiography showed high intracoronary thrombus burden and total occlusion of the proximal segment of left anterior descending artery. Percutaneous coronary intervention was then performed as the treatment of choice, and resulted with no residual stenosis after. The patient had a smooth and progressive recovery.

RESUMO

Purpose: This study aimed to explore the sexual behaviors and intimate relationships of sexual partners of young patients with cervical cancer. Patients and Methods: This study employed a descriptive phenomenological research design, which falls within the realm of qualitative research methods. Qualitative research typically utilizes interview techniques for gathering participants' experiences, perceptions, and behaviors. This study conduct face-to-face semi-structured interviews with the sexual partners of 15 young cervical cancer patients receiving cancer treatment to collect their experiences and perspectives on intimate relationships and sexual behavior with cervical cancer patients, and use the Colaizzi method for data analysis. Results: Four themes were identified through the interview analysis: (1) reduction or absence of sexual behavior, (2) unpleasant sexual experiences, (3) adjustment of intimate relationships, and (4) lack of sexual health education. Conclusion: The sexual partners of young cervical cancer patients have experienced significant shifts in their perspectives on sexual behavior and intimate relationships. These changes include reduction or absence of sexual behavior, unpleasant sexual experiences, adjustment of intimate relationships, and lack of sexual health education. Hospitals should pay more attention to the sexual behavior and intimate relationships of patients with cervical cancer and their sexual partners, and social support systems and psychological and emotional counselling services should be established for providing relevant knowledge and guidance.

RESUMO

Aim: To compare health-related quality of life (HRQoL) in young survivors of out-of-hospital cardiac arrest (OHCA) in Norway with an age and sex-matched reference population and to assess the associations between exercise volume prior to OHCA and HRQoL after. Methods: We present data from survivors aged 18-50 years registered with OHCA in the Norwegian Cardiac Arrest Registry between January 1st 2015 and December 31st 2017. Survivors were invited to answer two questionnaires; (1) the Short Form 36 (SF-36) Health Survey Version 1, and (2) about exercise habits prior to OHCA. Respondents were randomly matched 1:1 for age and sex with a reference population (data were available from the Norwegian Centre for Research Data). Results: Of the 175 survivors invited, 95 (54%) responded, median age was 44 (range 35-48) years, 26 (27%) females. Valid results for SF-36 were available for 91 survivors, of whom 87 reported pre-OHCA exercise-volume. Prior to OHCA, 21 did no regular exercise, 44 exercised 1-4 hours/week and 22 exercised ≥5 hours/week. Compared to the reference population survivors had significantly (p < 0.01) poorer SF-36 scores for scales relating to physical- and mental health. SF-36 scale scores were similar in survivors who did and did not exercise regularly. Within the regular exercisers, survivors reporting ≥5 hours of exercise/week had better SF-36 scores than those exercising less. Conclusion: Poorer HRQoL in survivors compared to the reference population should prompt us to explore how treatment and rehabilitation could be improved and adapted. More exercise before OHCA favoured better HRQoL after, which aligns well with the recognised positive association between HRQoL and physical activity in general.

RESUMO

OBJECTIVE: To identify and study variants of the clinical course of the acute period of ischemic stroke (IS) in young and middle-aged patients, to establish their dependence on the presence of the main risk factors for cardiovascular diseases. MATERIAL AND METHODS: The study included 145 patients (111 men and 34 women) with IS in its acute period, including 22 young (15.2%) and 123 middle-aged people (84.8%). The main risk factors of cardiovascular diseases were analyzed. Five variants of the clinical course of the acute period of IS were identified: regredient, regredient with residual mild focal neurological symptoms, stable, slowly progressive, and rapidly progressive. The regredient course and the regredient course with residual mild focal neurological symptoms are attributed to the favorable course of the acute period of IS; stable, progressive, and rapidly progressive predicted unfavorable course. RESULTS: Regredient course was observed in 43 (29.7%) patients; regredient with residual mild focal neurological symptoms in 78 (53.8%) patients; stable course was established in 4 (2.8%) patients; slow progressive course in 15 (10.3%) patients and fast progressive course in 5 (3.4%) patients. The following risk factors significantly contributed to the favorable course: less pronounced motor, sensory and speech disorders at the time of admission of the patient to the hospital and at the end of the acute period of IS, timely hospitalization in the neurological department for the treatment of patients with acute disorders of cerebral circulation within the «therapeutic¼ window, intravenous thrombolytic therapy, mild severity of IS on the NIHSS, a lesion of the vertebral-basilar brain basin, absence of overweight and ischemic heart disease in the patient's anamnesis (p<0.05). CONCLUSION: Determining the clinical course of the acute period of IS in young and middle-aged patients will make it possible to predict the rehabilitation potential of a particular patient and increase the effectiveness of individual neurorehabilitation measures at the stages of early and late rehabilitation treatment.

RESUMO

Research has recognized age biases against young leaders, yet understanding of how gender, the most frequently studied demographic leader characteristic, influences this bias remains limited. In this study, we examine the gender-specific age bias toward young female and young male leaders through an intersectional lens. By integrating intersectionality theory with insights on status beliefs associated with age and gender, we test whether young female and male leaders face an interactive rather than an additive form of bias. We conducted two preregistered experimental studies (N1 = 918 and N2 = 985), where participants evaluated leaders based on age, gender, or a combination of both. Our analysis reveals a negative age bias in leader status ascriptions toward young leaders compared to middle-aged and older leaders. This bias persists when gender information is added, as demonstrated in both intersectional categories of young female and young male leaders. This bias pattern does not extend to middle-aged or older female and male leaders, thereby supporting the age bias against young leaders specifically. Interestingly, we also examined whether social dominance orientation strengthens the bias against young (male) leaders, but our results (reported in the SOM) are not as hypothesized. In sum, our results emphasize the importance of young age as a crucial demographic characteristic in leadership perceptions that can even overshadow the role of gender.
