Cancer is a complex disease that affects the physical and psychological well-being of the patient, their families, and caregivers. Indeed, cancer-related mental health disorders could impact treatment adherence, quality of life, and overall health outcomes. In addition, approximately 30% of patients may experience cancer-related psychological disorders, including anxiety, depression, and post-traumatic stress. Also, caregivers of patients with cancer can experience significant emotional, physical, and financial stress, which can have a negative impact on their health. Therefore, to address these issues, mental health resources should be integrated into cancer care settings to identify and intervene early for individuals with psychological distress. Hence, providing psychological support, counseling, and education about coping strategies could create a safe and supportive environment where individuals can express their emotions, reducing feelings of isolation and depression. However, there are some important barriers to accessing mental health support for individuals with cancer, including stigma, cultural attitudes, and financial and logistical challenges. Hence, strategies to overcome these barriers include increasing awareness and education about the importance of mental health care, providing integrated care that addresses both physical and mental health needs, and utilizing telehealth services. So, healthcare providers should continue to develop and implement innovative approaches to mental health care that are tailored to the essential requirements of individuals with cancer and to enhance knowledge regarding the key roles of mental health care for individuals with cancer.
Konsument na rynku kapitałowym
Authors: Wierzbowski Marek
Published: August 2024

Artykuł poświęcony jest traktowaniu inwestorów – osób fizycznych – jako konsumentów na rynku kapitałowym, co może skutkować objęciem ich ochroną przewidzianą dla konsumentów. W instytucjach finansowych budzi to obawy o możliwość przyznawania przez sądy inwestorom ochrony właściwej dla konsumentów, natomiast ochronie inwestorów poświęcone są odrębne przepisy i to one powinny znajdować przede wszystkim zastosowanie dla ochrony tej grupy uczestników obrotu finansowego. Inwestycje na rynku kapitałowym niosą za sobą ryzyko strat, które nie może być całkowicie usunięte lub przeniesione na instytucje finansowe. Ochrona inwestorów opiera się przede wszystkim na dostarczeniu im informacji o planowanych inwestycjach, pozostawiając im decyzje co do podjęcia ryzyka, z którym wiąże się dana inwestycja.

Швидкісно силові здібності є провідними для досягнення високих результатів у сучасному боксі. Разом з тим, підбір ефективних стратегій розвитку швидкісно силових здібностей у боксерів на етапі спеціалізованої підготовки досліджено недостатньо. У зв’язку з цим, метою дослідження є вивчення ефективності програми вдосконалення швидкісно силових здібносте боксерів на етапі спеціалізованої підготовки. Методи дослідження: теоретичний аналіз та узагальнення даних у науковій та методичній літературі, педагогічне спостереження, методи вивчення рівня розвитку фізичних якостей (хронодинамометрія, метод контрольних вправ), педагогічний експеримент, методи математичної статистики. Результати. За допомогою аналізу даних науково методичної літератури розроблено тренувальну програму, основними засобами розвитку швидкісно-силових здібностей  були - метод повторної вправи з використанням ненасичених обтяжень та з обмеженою кількістю повторень (до відмови), метод повторних тренувань з максимальними та близькими до максимальних зусиллями для створення максимальної м'язової сили та розвитку вибухової сили, метод ізометричних зусиль для розвитку сили в статичному стані, виконання максимально сильних проте повільних ударів у серіях спуртів (5 спуртів*2 хв), поступове – до 3 спуртів по 2 хв наростання швидкості (темпу) та деяке зниження сили ударів (у такому режимі – 3 спурти по 2 хв). З часом – максимально можливе виконання темпу ударів та збереження їх сили, колове тренування, яка має комплексний вплив на низку м'язових груп. Вправи виконувалися на станціях і підбираються таким чином, щоб кожна серія працювала на різні групи м'язів.  Другий підхід вдосконалення швидкісно силових здібностей боксерів полягав у розвитку внутрішньої та міжм’язевої координації. Враховувалися індивідуальні особливості боксерів, вплив вправ на них, коригування навантаження з урахуванням індивідуальних особливостей та реакції на запропоновані вправи. Основною умовою було виконання рухів з дотриманням їх координаційної структури і зі швидкістю, що дорівнює виконанню ударів під час змагальної діяльності або швидше. Підбір вправ для вдосконалення швидкісно силових здібностей боксерів на етапі спеціалізованої базової підготовки з урахуванням індивідуальних особливостей боксерів (підбір обтяжень та кількості повторень, інтервальні навантаження), мали позитивний вплив на рівень розвитку швидкісно силових здібностей боксерів. Показники виконання вправ, які характеризують рівень розвитку загальної та спеціальної швидкісно силової підготовки, мали статистично значущі покращення у боксерів експериментальної групи у порівнянні з показниками до експерименту, та з показниками боксерів контрольної групи після експерименту. Це свідчить про ефективність запропонованих вправ, які сприяють удосконаленню рівня швидкісно силових здібностей боксерів на етапі спеціалізованої базової підготовки.

Rocky Mountain High Titer: An Unusual Delay In Surgical Clearance
Authors: Huang Lisa Ting , Murray Victoria Wong , Lightfood Judith Anne
Published: August 2024

Rocky Mountain Spotted Fever, carried by a variety of ticks, is classically caused by Ricksettsia rickettsii, but may be clinically indistinguishable from other bacteria in the same family. A 47 year old female presented in December for presurgical clearance due to fever, petechial rash on the thighs and trunk, and ecchymoses on the forearms, gluteal region, and toes; additional symptoms included arthralgia in bilateral lower limbs. Bacterial infection was suspected and empirical doxycycline was initiated pending specific PCR testing. Patient adherence was unclear at the followup visit, so IV ceftriaxone was initiated and repeated immunoglobulin testing was ordered to follow her course. Her symptoms waxed and waned over the next several weeks, but ultimately improved and resolved over the next two months, at which point she was successfully cleared for surgery. This case was unusual as she presented in December but disease prevalence typically wanes by August. She was evaluated by rheumatology and dermatology for arthralgia and rash prior to presentation to infectious disease service, but prior treatment was unsuccessful; a missed opportunity to prevent delay in surgery and potential sequelae of long-term infectious vasculitis. As changes in climate increase host range for the variety of vectors, geographic range and temporal duration is also expected to increase, and so it should be considered in the differential more frequently.
Relationship Between Gut Microbiota and Dementia
Authors: Ahmed Saad , Harris Zackary , Levi Russell David
Published: August 2024

This paper explores the complex relationship between gut microbiota, dietary habits, and dementia, focusing particularly on Alzheimer's disease (AD). Growing evidence suggests a significant link between the composition of gut bacteria, dietary choices, and susceptibility to dementia. Notably, individuals with dementia demonstrate a noticeable reduction in gut bacteria diversity, highlighting the crucial role of a balanced microbiome in maintaining cognitive health. Conversely, dietary preferences characterized by excessive consumption of processed foods and sugars are associated with an increased risk of dementia, emphasizing the critical influence of diet on shaping gut microbiota and subsequent neurocognitive outcomes. Importantly, dietary interventions featuring a diverse range of fiber and fermented foods emerge as promising strategies for reducing dementia risk, creating an optimal gut environment conducive to the production of anti-inflammatory agents and short-chain fatty acids. While ongoing research continues to elucidate the intricate mechanisms governing the gut-brain axis, current evidence underscores the importance of dietary modifications as a fundamental approach in dementia prevention and management. Specifically, adherence to dietary patterns resembling the Mediterranean diet or emphasizing high-fiber intake holds significant potential in alleviating the burden of dementia. Through a comprehensive examination of existing literature, this study provides valuable insights into the complex interplay between gut microbiota, dietary influences, and dementia risk, laying the groundwork for future medical interventions aimed at preserving cognitive function and mitigating the impact of dementia.

This study focuses on Krzysztof Kieślowski’s socio-political commentary and artistic expression in Camera Buff (Amator, 1979). The reason for mapping Kieślowski’s political stance stems from his deep engagement with subtle and profound cinematic expression within the Cinema of Moral Anxiety, where directors skillfully forged artistic avenues as a counter to the dominant narrative and censorship imposed by the socialist realist doctrine. This creative defiance birthed not only a novel approach to filmmaking but also a distinct mode of political assertion in a restrictive environment. Directors within this movement stand as exemplars of conscious opposition to state intervention, fostering unique artistic practices in defiance of oppressive systems. Amidst a political climate marked by censorship and stringent controls, the emergence of the Cinema of Moral Anxiety holds significant political and artistic weight. Within Cinema of Moral Anxiety movement Kieślowski’s Camera Buff reflects his resistance to the dominant political order and its censorship mechanisms. To analyze the distinctive features of Kieślowski’s political cinematic expression and the ways through which he dismantles the system in Camera Buff, this study proceeds in two steps. First, it examines how socialist realism is juxtaposed with the ethos of the Cinema of Moral Anxiety. Second, it examines how Kieślowski employs self-reflexivity and metaphor to reflect the themes of the Cinema of Moral Anxiety in Camera Buff. In both steps, metaphor and self-reflexivity are underlined as potent forms of political stance and expression. This essay concludes by demonstrating how Camera Buff embodies the principles of Moral Anxiety Cinema, offering a critique of societal norms and political oppression through self-reflexive storytelling.
Approximating a continuously stratified hydrostatic system by the multi-layer shallow water system
Authors: Adim Mahieddine
Published: August 2024

In this article we consider the multi-layer shallow water system for the propagation of gravity waves in density-stratified flows, with additional terms introduced by the oceanographers Gent and McWilliams (Journal of Physical Oceanography 20 (1990) 150–155) in order to take into account large-scale isopycnal diffusivity induced by small-scale unresolved eddies. We establish a bridge between the multi-layer shallow water system and the corresponding system for continuously stratified flows, that is the incompressible Euler equations with eddy-induced diffusivity under the hydrostatic approximation. Specifically we prove that, under an assumption of stable stratification, sufficiently regular solutions to the incompressible Euler equations can be approximated by solutions to multi-layer shallow water systems as the number of layers, N, increases. Moreover, we provide a convergence rate of order 1 / N 2 . A key ingredient in the proof is a stability estimate for the multi-layer system which relies on suitable energy estimates mimicking the ones recently established by Bianchini and Duchêne (Bianchini and Duchêne (2024)) on the continuously stratified system. This requires to compile a dictionary that translates continuous operations (differentiation, integration, etc.) into corresponding discrete operations.

BACKGROUND: Mesenteric lymphadenitis (ML) demonstrates a distinctive inclination for the pediatric and adolescent demographic and the diagnosis of ML in young children poses a substantial challenge. OBJECTIVE: This prospective study aimed to assess the diagnostic efficacy of Superb Microvascular Imaging (SMI) and Virtual Touch Tissue Imaging quantification (VTIQ) in distinguishing pediatric mesenteric lymphadentitis. METHODS: We examined 82 mesentric lymph node (MLN) in pediatric patients with mesenteric lymphadentitis and 50 MLN in a healthy group. SMI was utilized to evaluate vascularity within the MLN, while MLN stiffness, quantified as shear wave velocity (SWV) in meters per second (m/s), was assessed using VTIQ. We compared the diagnostic performance of greyscale Ultrasound, US combined with SMI, US combined with VTIQ, and US combined with both SMI and VTIQ. RESULTS: SMI revealed a significant distinction between mesenteric lymphadentitis and normal MLN (p <  0.001). MLN affected by mesenteric lymphadentis exhibited increased vascularity (marked vascularity: 13/82, 15.85%) compared to normal MLN (marked vascularity: 1/50, 2.00%). Statistically significant differences were observed in SWV values beween mesenteric lymphadentitis and normal MLN (all p-values <0.001). The mean and minimum SWV values for MLN with mesenteric lymphadentitis were 1.66±0.77 m/s and 1.51±0.53 m/s, respectively. Control group SWV values were approximately three times higher than those in the mesenteric lymphadenitis group. The highest area under the curve values were achieved with the combination of all three modalities (0.837, 95% confidence interval: 0.763– 0.896), followed by US + VTIQ (0.795, 0.716– 0.860), US + SMI (0.753, 0.670– 0.824) and US alone (0.642, 0.554– 0.724). CONCLUSION: SMI and VTIQ offer a promising noninvasive adjunct to grayscale ultrasound for identifying mesenteric lymphadentitis in pediatric patients.

OBJECTIVE: The aim of this study is to investigate the correlation between the triglyceride-glucose-body mass index (TyG-BMI) and the characteristics of various carotid plaques in middle-aged and elderly patients with acute myocardial infarction (AMI). METHODS: A retrospective study was conducted on 380 patients with AMI hospitalized in the Cardiology Department of Kaifeng Central Hospital. Based on carotid ultrasound results, patients were divided into the following two groups: the stable plaque group and the unstable plaque group. Additionally, a control group comprising 380 healthy individuals visiting the hospital’s physical examination center during the same timeframe was established. Fasting venous blood samples were collected from all participants to measure blood glucose and triglyceride. The baseline TyG-BMI index was calculated using the formula Ln [fasting triglyceride (mg/dL)×fasting blood glucose (mg/dL)/2]×BMI. The correlation between different plaque groups and the TyG-BMI index was analyzed. RESULTS: The TyG-BMI index was significantly higher in the unstable plaque group compared to the stable plaque group, with values of 252.81±29.99 and 201.92±28.72, respectively (P = 0.034). Spearman’s correlation analysis showed a positive correlation between the instability of carotid plaques and the TyG-BMI index in patients with AMI (r = 0.521, P = 0.003). Logistic regression analysis indicated that the TyG-BMI index was an important risk factor for unstable carotid plaques in patients with AMI (OR = 2.691, 95% CI: 1.169–4.123). CONCLUSION: The findings of this study suggest that an elevated TyG-BMI index significantly increases the risk of unstable carotid plaques in patients with AMI, making it an important risk factor for carotid plaque instability.

Background: Exposure to lead (Pb) is a major public health problem that could occur through contaminated soil, air, food, or water, either during the course of everyday life, or while working in hazardous occupations. Although Pb has long been known as a neurodevelopmental toxicant in children, a recent and growing body of epidemiological research indicates that cumulative, low-level Pb exposure likely drives age-related neurologic dysfunction in adults. Environmental Pb exposure in adulthood has been linked to risk of late-onset Alzheimer’s disease (AD) and dementia. Objective: Although the biological mechanism underlying this link is unknown, it has been proposed that Pb exposure may increase the risk of AD via altering the expression of AD-related genes and, possibly, by activating the molecular pathways underlying AD-related pathology. Methods: We investigated Pb exposure using a line of genetically modified mice with AD-causing knock-in mutations in the amyloid precursor protein and presenilin 1 (APPΔNL/ΔNL x PS1P264L/P264L) that had been crossed with Leprdb/db mice to impart vulnerability to vascular pathology. Results: Our data show that although Pb exposure in adult mice impairs cognitive function, this effect is not related to either an increase in amyloid pathology or to changes in the expression of common AD-related genes. Pb exposure also caused a significant increase in blood pressure, a well known effect of Pb. Interestingly, although the increase in blood pressure was unrelated to genotype, only mice that carried AD-related mutations developed cognitive dysfunction, in spite of showing no significant change in cerebrovascular pathology. Conclusions: These results raise the possibility that the increased risk of dementia associated with Pb exposure in adults may be tied to its subsequent interaction with either pre-existing or developing AD-related neuropathology.
Post-Metastasectomy Adjuvant Therapy in Patients with Renal Cell Carcinoma: A Systematic Review
Authors: Monda Steven , Lara Primo N. , Gulati Shuchi
Published: August 2024

BACKGROUND: Pembrolizumab is established as adjuvant therapy for patients with high-risk clear cell renal cell carcinoma (ccRCC) after resection. Patients with completely resected metastatic disease (M1 NED) seem to have greater benefit from adjuvant pembrolizumab in both disease-free survival (DFS) and overall survival (OS); yet, with other agents, adjuvant therapy has not been shown to improve survival. As newer therapies evolve, it is important to understand the efficacy of systemic agents in this patient population. OBJECTIVE: We aimed to systematically review available trials investigating adjuvant therapy after metastasectomy in RCC. METHODS: Following PRISMA guidelines, we performed a systematic literature search using PubMed and Embase through January 2024. For inclusion, studies were required to include completely resected patients with known metastatic RCC. Patients with only locally advanced and/or regional nodal involvement (N1) alone were excluded. Titles and abstracts were screened to identify articles for full-text, and then a descriptive review was performed. RESULTS: A total of 149 articles were initially identified. Ultimately 9 articles published before the end of January 2024 met our inclusion criteria and were included in the analysis. Data were extracted and organized to reflect the role of adjuvant treatment - both targeted therapies as well as immunotherapy in patients who had undergone metastasectomy and rendered M1 NED. With the exception of pembrolizumab, adjuvant therapy in M1 NED was not found to be associated with improved survival. CONCLUSIONS: Pembrolizumab appears to benefit M1 NED ccRCC patients after resection even more than other high-risk ccRCC patients. Yet, this same benefit has not been seen with other agents. Future research should focus on trying to establish which M1 NED patients benefit from adjuvant treatment.
