Obesity is characterized by a chronic inflammation driven primarily by sustained activation of the canonical NF-κB signaling pathway. This persistent inflammatory state originates in hypertrophic adipose tissue and progressively affects multiple organ systems, contributing to systemic metabolic dysfunction. This review explores the molecular architecture and regulatory components of the canonical NF-κB pathway and outline how metabolic stressors, cytokines, chemokines, adhesion molecules, and dysregulated microRNAs influence its activity in obesity. Clinically relevant NF-κB linked biomarkers are characterized, those that reflect the degree of inflammation and may support risk stratification in metabolic disease. Finally, we discuss emerging therapeutic strategies, including small-molecule inhibitors, monoclonal antibodies, and miRNA-based approaches designed to modulate NF-κB activity while preserving its essential physiological roles. Together, these insights emphasize the central involvement of NF-κB in obesity-associated inflammation and highlight potential targets for selective intervention.

The aim of our study was to assess the prognostic value of the two new grading systems based on the quantification of tumor budding - TB (GBd) and poorly differentiated clusters - PDCs (PDCs-G) in colorectal carcinomas (CRC). We performed a retrospective study on 71 CRC patients who underwent surgery at the Emergency County Hospital, Timișoara. CRC cases were classified based on haematoxylin-eosin slides, using the conventional grading system, GBd and PDCs-G, respectively. We used two-tier and three-tier grading schemes for each system. Subsequently, we evaluated associations with other prognostic factors in CRC. Based on the three-tier GBd (GBd-3t) most cases (34/69, 49.27%) were classified as G3Bd-3t, while based on the conventional grading system, the majority of the cases (55/69, 79.71%) were considered G2. On the other hand, based on the three-tier PDCs-G system (PDCs-G-3t), most cases (31/69, 44.93%) were PDCs-G2-3t. We also noted a more significant association of GBd-3t with other prognostic parameters analyzed, as compared to the conventional grading system. Nodal status, tumor stage, and lymphovascular invasion were strongly correlated with GBd-3t (p=0.0001). Furthermore, we noted that PDCs-G-3t correlated more significantly than the conventional grading system with nodal status (p<0.0001), tumor stage (p=0.0003), lymphovascular invasion (p<0.0001), perineural invasion (p=0.005) and the tumor border configuration (p<0.0001). High GBd and PDCs-G grades correlate directly with other negative prognostic factors in CRC.Thus, these new parameters/classification methods could be used as additional tools for risk stratification in patients with CRC.

Background and Objectives: primary thyroid lymphoma (PTL) is a rare neoplasm, displaying a variety of histological features. It is often a challenge for pathologists to diagnose this tumor. Materials and Methods: this study is a retrospective analysis of clinical and pathological characteristics of a group of eleven patients (eight women and three men, mean age 68 years, range 50–80 years) diagnosed with PTL. Results: nine patients (81.81%) presented a tumor with progressive growth in the anterior cervical region, usually painless and accompanied by local compressive signs. Histologically, we identified six cases (55%) of diffuse large B-cell lymphoma, three cases (27%) of extranodal marginal zone lymphoma, one case (9%) of follicular lymphoma, and one case (9%) of mixed follicular-diffuse lymphoma. PTL was associated with microscopic Hashimoto autoimmune thyroiditis in ten cases (90.9%). Ten patients (90.9%) presented with localized disease (stage I-IIE). A percentage of 60% of patients survived over 5 years. We observed an overall longer survival in patients under 70 years of age. Conclusions: PTL represents a diagnosis that needs to be taken into account, especially in women with a history of Hashimoto autoimmune thyroiditis, presenting a cervical tumor with progressive growth. PTL is a lymphoid neoplasia with favorable outcome, with relatively long survival if it is diagnosed at younger ages.

Background and objectives: We aimed to assess the significance of sex and age compared to other clinical-pathological parameters in colorectal cancer (CRC). Materials and methods: Our study included a retrospective approach to CRC patients who underwent surgery at the ‘Pius Brinzeu’ County Clinical Emergency Hospital in Timisoara (PBECCHT), Romania. The analyzed parameters were: patient age and sex, tumor location, histological type, differentiation grade (G), extent of tumor (pT), lymph-node status (pN), distant metastasis status (pM), and lymphovascular invasion (LVI). The population was divided into three groups based on age, with those under 49 years old, 50 to 69 years old, and elderly (>70). Results: The study’s inclusion criteria were met by 1885 patients, with a male-to-female ratio of 1.39:1. There were significant differences between the sexes in the anatomical location of tumors (p < 0.0001). Younger patients were more likely to have deeply invasive tumors (p = 0.0096), LVI (p = 0.0332), lymph-node metastases (p = 0.0158), and metastatic disease (p = 0.0017). Conclusions: Over the ten-year period reviewed, the frequency of CRC cases has progressively increased, with males being diagnosed more often. In terms of patient age, the young population exhibits clinical features of aggressive evolution. Patient sex did not influence the analyzed parameters, except for tumor location, where right colon tumors are slightly more common in females.

Introduction: The COVID-19 pandemic had a significant impact on the healthcare system, leading to a prioritization of hospital admissions in many countries. Romania was no exception, and it had to restrict patient access to medical services in hospitals with chronic diseases and oncological pathology, including thyroid cancer. This study aimed to compare the clinical and pathological factors of patients with nodular thyroid disease diagnosed and surgically treated during the two years before and after the COVID-19 pandemic, in a single medical institution.Methods: The retrospective study included 1505 patients who were diagnosed and operated on for nodular thyroid disease between January 2018 and December 2021. The patients were divided into two groups: the “PRECOVID” group (January 2018 to February 2020), and the “POSTCOVID” group (March 2020 to December 2021). The analyzed parameters included patients’ gender, age, preoperative diagnosis, type of surgical intervention, and pathological diagnosis.Results: A significant decrease was observed in the number of surgeries performed for thyroid nodular disease during the COVID-19 pandemic period (450 versus 1055 cases, p<0.00001). There was a significant decrease in the number of surgical reinterventions (0.9% in the POSTCOVID group versus 2.9% in the PRECOVID group, p=0.01) and a significant increase in the number of total thyroidectomies (84.9% in the POSTCOVID group versus 80.1% in the PRECOVID group, p=0.02). We also observed a higher incidence of malignant/borderline tumors in the POSTCOVID group compared to the PRECOVID group (p=0.04) and a significantly higher frequency of aggressive forms of thyroid cancer in the POSTCOVID group (p=0.0006).Discussion: The COVID-19 pandemic had a significant impact on the surgical management of nodular thyroid disease, resulting in a decrease in surgeries and a change in the type of surgical interventions performed. The higher incidence of malignant/borderline tumors diagnosed during the pandemic highlights the importance of timely diagnosis and treatment of thyroid nodules to prevent cancer progression.

A granular cell tumor (GCT) is a rare neoplasia that originates from Schwann cells. It usually appears in the skin or soft tissues, but it may occur anywhere in the body. The gastrointestinal tract is an unusual developmental site for a GCT, the esophagus being the most common site of origin for this tumor. The stomach is one of the most unique sites of origin for GCT, with less than 80 cases being mentioned in the literature. Histologically, GCTs consist of fusiform and polygonal cells, with granular cytoplasm, arranged in compact ‘nests’. Immunohistochemically, these tumors show positivity for S100 protein, CD68, CD56 and, in a smaller percentage, they are positive for other antibodies, most notably inhibin alpha. We report the case of a 52‑year‑old woman with a solitary GCT that had developed in the gastric cardia, discovered on a routine gastroscopy and successfully treated by endoscopic submucosal dissection.
