The continuous evolution of cancer biology has led to the discovery of mammaglobin, a potential novel biomarker for breast carcinoma. This review aims to unravel the enigmatic aspects of mammaglobin and elucidate its potential role in redefining the paradigm of breast carcinoma biomarkers. We will thoroughly examine its expression in tumoral and peritumoral tissues and its circulating levels in the blood, thereby providing insights into its possible function in cancer progression and metastasis. Furthermore, the potential application of mammaglobin as a non-invasive diagnostic tool and a target for personalized treatment strategies will be discussed. Given the increasing incidence of breast carcinoma worldwide, the exploration of novel biomarkers such as mammaglobin is crucial in advancing our diagnostic capabilities and treatment modalities, ultimately contributing to improved patient outcomes.

The insular cortex has emerged as a key region implicated in a wide array of cognitive, emotional, and sensory processes. The anterior part of the insula (AIC) is central to emotional awareness, decision-making, and interoception, while the posterior insula (PIC) is more associated with somatosensory processing. The insula acts as a functional hub within the salience network and integrates homeostatic, affective, and cognitive information; thus, its role in different mental disorders seems to be prominent. Altered structure and connectivity of the insular cortex are evident in several psychiatric conditions. In schizophrenia, reductions in insular volume—especially on the left—correlate with hallucinations, emotional dysregulation, and cognitive deficits. Bipolar and major depressive disorders exhibit AIC volume loss and aberrant connectivity patterns linked to impaired affect regulation and interoceptive awareness. Anxiety disorders show functional hyperactivity of the insula, especially in response to fear-inducing stimuli, though findings on structural changes are mixed. Overall, growing evidence underscores the insular cortex’s central role in psychiatric pathophysiology and highlights its potential as a target for future diagnostic and therapeutic strategies.

Obstructive sleep apnea (OSA) is characterized by repetitive complete or partial collapse of the upper airway and reduction of airflow during sleep. It is associated with significantly increased daytime muscle sympathetic nerve activity thought to result from the repetitive intermittent periods of hypoxemia during sleep and brain alterations that are likely to result. Different brain regions are affected by subsequent hypoxia/anoxia. Neurodegenerative processes result in measurable atrophy of cortical gray matter in the temporal lobes and posterior cingulate cortex, as well as in subcortical structures such as the hippocampus, amygdala, and thalamus. This study involved a group of firstly diagnosed, therapy-naive, nonalcoholic fatty liver disease (NAFLD) patients, out of which 144 (96 males and 48 females), aged 34–57 (mean 47.88 ± 6.07), satisfied the recruiting criteria for the study and control groups. All the patients underwent MRI scanning, polysomnography testing, and cognitive evaluation. Cognitively, worse results were obtained in the group with OSA (p < 0.05) and NAFLD (p = 0.047). A significant decrease in volumes of cortical and subcortical structures was revealed (p < 0.001). In conclusion, brain deterioration followed by cognitive impairment is, most likely, the result of intermittent hypoxia and anoxia episodes that initiate the domino process of deteriorating biochemical reactions in the brain.

Methods based on the evaluation of textural patterns in microscopy, such as the “gray-level co-occurrence matrix” (GLCM) analysis are modern and innovative computer and mathematical algorithms that can be used to quantify subtle structural changes in cells and their organelles. Potential application of GLCM method in the fields of psychophysiology and psychiatry to this date has not been systematically investigated. The main objective of our study was to test the existence and strength of the association between chromatin structural organization of peripheral blood neutrophils and levels of self-perceived mental stress. The research was done on a sample of 100 healthy student athletes, and the Depression, Anxiety, and Stress Scales (DASS-21) were used for the estimation of psychological distress. Chromatin textural homogeneity and uniformity were negatively correlated (p < 0.01) with mental distress and had relatively good discriminatory power in differentiating participants with normal and elevated stress levels. As an addition, we propose the creation of a machine learning model based on binomial logistic regression that uses these and other GLCM features to predict stress elevation. To the best of our knowledge, these results are one of the first to establish the link between neutrophil chromatin structural organization quantified by the GLCM method and indicators of normal psychological functioning.

Background and Aims: Non-alcoholic fatty liver disease (NAFLD) is a metabolic disease with extensive multi- organ involvement, whose extra-hepatic manifestations include diabetes mellitus type 2, cardiovascular disease, obstructive sleep apnea (OSA), chronic kidney disease, and polycystic ovary syndrome. Our hypothesis was that there was a strong psychological component in NAFLD and OSA suffering patients and that psychotherapy would be helpful in the treatment of the mentioned diseases. Methods: Of 144 initially selected patients (with NAFLD, obesity and OSA), 32 patients agreed to undergo psychotherapy, and 31 therapy-naive NAFLD and OSA patients agreed to participate as controls. Results: Psychological evaluation revealed that self-esteem rose significantly after one-year psychotherapy (p=0.005). Body mass index (BMI) was significantly lower after psychotherapy, followed by the changes in laboratory results. Binomial logistic regression revealed that the reduction of BMI in high probability led to self-esteem improvement (p=0.03). Conclusions: Psychotherapy was an efficient supporting method in the treatment of patients with NAFLD, obesity and OSA. It raised self-esteem and stimulated the motivation for further treatment of obesity, as one of the important factors for NAFLD and OSA. Still, it is advisable to use psychotherapy in combination with other clinical methods of treatment.

Out of all benign tumors of the ceruminous glands, syringocystadenoma papilliferum is the rarest and represents only 2% of cases. It is an extremely rare benign tumor that originates from modified apocrine sweat glands. The aim of this paper was to present, according to our findings, the 18th case of syringocystadenoma papilliferum in the external auditory canal, with a detailed review of its clinical, radiological and histomorphological characteristics. A 59-year-old man reported to our clinic due to a 5×5 mm papillomatous growth at the entrance to the right external auditory canal. Histopathology indicated, after an excisional biopsy, that it was a syringocystadenoma papilliferum. The resection lines were free of tumor tissue, and the patient has no signs of tumor recurrence. Although rare, it should be considered as a differential diagnosis of lesions in this region. Complete excision is mandatory in order to avoid recurrence and potential malignant alteration.
