Introduction: In this retrospective study, the authors evaluated whether obesity-induced immunomodulation impacts the expression of programmed death ligand-1 (PD-1L) in lung cancer cells.Methods: A retrospective cross-sectional study was performed. The study included 67 patients. The data did not have a normal distribution.Results: For women, using ANOVA test (p = 0.050) with post-hoc analysis, a statistically significant difference in expression was found between women with overweight and women with normal weight (p = 0.040).Conclusions: Apart from the above, the authors did not find any statistically significant correlation between PD-1L expression on lung cancer cells and body mass index, either in the whole group or in histological subgroups.

A thyroid gland is one of the most important organs of a human body. Thyroid hormones, at least in physiological concentration, have anabolic features. The aid of this review is to summarize knowledge on potential usage of thyroid hormones in sport doping. Thyroid hormones play a crucial role in skeletal muscles physiology. The exposition to T3 and T4 may improve myogenesis, muscles regeneration and muscles blood blow. In a long-time perspective, those hormones may help in reducing body weight. According to those mechanisms, thyroid hormones may be considered as a plausible agent in sport doping. However WADA guidelines does not include T3 or T4 in a list o sport doping substances, the debate on their inclusion is on-going, and the physicians should be aware of thyroid hormones effects on human metabolism from sports medicine perspective.

Multiple sclerosis (MS) is a serious neurological disease, the actual worldwide prevalence of which is estimated to be 2,8 million people (35,9 per 100,000). During the course of MS, various neurological symptoms and its complications result in raising patient disability, which range from skeletal muscles impairment, to losses in cognitive functions. Achieving control over course of MS progression appears to be crucial in its treatment. This enforces the need for recognizing novel predictive factors so as to allow prognosis of future remissions and/or progressions. Adiponectin, hormone secreted by adipose tissue, currently is considered as a possible candidate for such a biomarker. The aim of this review is to summarise present knowledge and to assess possible clinical usage. According to collected data, adiponectin measurements in serum and cerebrospinal fluid appear to provide plausible and useful biomarkers in predicting the course of MS. Further studies are, however, needed, especially using non-invasive, but promising sources such as saliva.

Conn syndrome (CS), next to bilateral adrenal hyperplasia, is one of the most common causes of primary hyperaldosteronism. It leads to potentially curable secondary hypertension. The 54-year-old woman underwent an abdominal computed tomography (CT) examination for symptomatic nephrolithiasis. A focal lesion of the left adrenal gland was found with a diameter of 16 mm and a density of 34 Hounsfield units (HU). The lesion was under observation, and the next magnetic resonance imaging (MRI) scans showed a slight enlargement of the lesion to a size of 18 x 12 mm. The lesion was interpreted as an atypical adenoma of the adrenal gland. According to the course, the patient was referred to the endocrinology clinic. The patient's symptoms included hypertension and paresthesia. During two separate hospitalizations, Conn syndrome was diagnosed using a specific laboratory test. The patient was successfully treated by surgical intervention, resulting in remission of all symptoms. This case illustrates the difficulties in diagnosing primary hyperaldosteronism. The symptoms of Conn syndrome may vary in severity or may be absent. Early diagnosis and appropriate treatment can save many ill individuals from cardiovascular, metabolic, or renal complications. The case underscores the need for screening hypertensive patients using the aldosterone-renin ratio (ARR).

This article reviews the potential impact of herpes simplex viruses (HSV) on chronic fatigue syndrome (CFS). HSV-1 and HSV-2 are prevalent pathogens, with HSV-1 acquired early in life and HSV-2 typically transmitted sexually. Studies have shown an association between HSV and CFS, with HSV-1 detected in saliva and cerebrospinal fluid of CFS patients and elevated HSV-2 antibodies found in CFS patients. Immunological abnormalities, including increased pro-inflammatory cytokines and chemokines, suggest immune dysregulation in CFS patients infected with HSV. HSV infections can also disrupt the hypothalamic-pituitary-adrenal axis and autonomic nervous system, impacting energy metabolism regulation and contributing to CFS fatigue. Neuroinflammation, indicated by increased translocator protein binding in CFS patients' brains, may play a role in CFS symptoms. However, the mechanisms linking HSV to CFS and the contribution of viral-induced neuroinflammation are still unclear. Despite the evidence, understanding the complex interactions between HSV, immune responses, and other factors in CFS remains challenging. In conclusion, HSV, particularly HSV-1 and HSV-2, may contribute to CFS development. Further research is needed to unravel the mechanisms involved and identify potential therapeutic interventions.

SGLT-2 inhibitors (flozins) are one of the new classes of anti-diabetic drugs, used from 2012. They are highly recommended in case of intolerance or contraindication of metformin, but in Poland they are used usually as third-line drug after metformin and sulfonylurea. They growing popularity is caused by their significance in cardiovascular risk reduction and preventive role in according to diabetes complications like chronic kidney disease, or diabetes-induced dementia. The aid of this article is to summarize the knowledge on the risk of psoriasis development in diabetic patients cured with flozins. In according to the newest studies, flozins may be considered as a pro-psoriatic factor, increasing the risk of this skin disease, especially in patients with diabetic kidney disease. But on the other hand, SGLT-2 inhibitors have significantly decreasing effect on cardiovascular risk, which is increased in psoriatic patients.
