RESUMO

Obesity, a complex and multifactorial disease influenced by genetic, environmental, and psychological factors, has reached epidemic proportions globally, posing a significant health challenge. In addition to its established association with cardiovascular disease and type II diabetes, obesity has been implicated as a risk factor for various cancers. However, the precise biological mechanisms linking obesity and cancer remain largely understood. Adipose tissue, an active endocrine organ, produces numerous hormones and bioactive molecules known as adipokines, which play a crucial role in metabolism, immune responses, and systemic inflammation. Notably, adiponectin (APN), the principal adipocyte secretory protein, exhibits reduced expression levels in obesity. In this scoping review, we explore and discuss the role of APN in influencing cancer in common malignancies, including lung, breast, colorectal, prostate, gastric, and endometrial cancers. Our review aims to emphasize the critical significance of investigating this field, as it holds great potential for the development of innovative treatment strategies that specifically target obesity-related malignancies. Furthermore, the implementation of more rigorous and comprehensive prevention and treatment policies for obesity is imperative in order to effectively mitigate the risk of associated diseases, such as cancer.

RESUMO

Cholangiocarcinoma (CCA) is a malignant neoplasm arising in the epithelium of the biliary tract. It represents the second most common primary liver cancer in the world, after hepatocellular carcinoma, and it constitutes 10-15% of hepatobiliary neoplasms and 3% of all gastrointestinal tumors. As in other types of cancers, recent studies have revealed genetic alterations underlying the establishment and progression of CCA. The most frequently involved genes are APC, ARID1A, AXIN1, BAP1, EGFR, FGFRs, IDH1/2, RAS, SMAD4, and TP53. Actionable targets include alterations of FGFRs, IDH1/2, BRAF, NTRK, and HER2. "Precision oncology" is emerging as a promising approach for CCA, and it is possible to inhibit the altered function of these genes with molecularly oriented drugs (pemigatinib, ivosidenib, vemurafenib, larotrectinib, and trastuzumab). In this review, we provide an overview of new biologic drugs (their structures, mechanisms of action, and toxicities) to treat metastatic CCA, providing readers with panoramic information on the trajectory from "old" chemotherapies to "new" target-oriented drugs.

RESUMO

The Monitoring Registries and negotiated agreements (MEAs) established by the Italian Medicines Agency (AIFA) exemplify a pinnacle of excellence in Italian healthcare governance, playing a pivotal role in achieving economic sustainability and ensuring judicious allocation of financial resources. Within a local territorial health company catering to a populace of around 1 million individuals in Italy, an assessment of the meticulous implementation of all negotiation procedures was carried out by scrutinizing the monitoring records. This examination served to pinpoint and address potential issues in the platform management executed by healthcare professionals, including physicians and pharmacists. Such issues had the potential to result in economic setbacks owing to the non-reimbursement from pharmaceutical companies. Through diligent verification undertaken by the pharmacists, a financial recovery amounting to approximately €579,443.4 for the fiscal year 2022 was achieved. The essence of this analysis is to underscore how collaborative, multidisciplinary efforts between physicians and pharmacists yield tangible economic advantages. This collaborative approach ensures a streamlined healthcare system characterized by efficiency, devoid of unnecessary expenditures, and marked by the highest standards of care appropriateness, ultimately serving the best interests of the citizens.

RESUMO

INTRODUCTION: Proton pump inhibitors (PPIs) constitute a widely utilized pharmaceutical class, frequently associated with notable instances of therapeutic inappropriateness. Such patterns of misuse not only contribute to elevated healthcare expenditure, but may also exacerbate clinical conditions in certain patients. METHODS: A comprehensive analysis was conducted between 2019 and 2023 to assess all prescriptions dispensed using the Anatomical, Therapeutic and Chemical (ATC) classification system, which allowed trends among primary PPIs to be visualized. This was achieved by calculating the defined daily dose (DDD) and then defining the total expenditure incurred on these drugs. RESULTS: With regard to the prescription of PPIs, an upward trend in consumption was observed with a decreasing expenditure, due to the phenomena of drug generics and increased competition between pharmaceutical companies, ranging from €9,512,481.22 in the first six months of 2019 to €8,509,820.80 in the first six months of 2023. From 2019 to 2023, consumption increased by approximately 3 million DDDs for a total ranging from 18,483,167.59 DDDs to 21,480,871.00 DDDs. Pantoprazole and esomeprazole, the most expensive drugs compared to omeprazole, rabeprazole and lansoprazole, accounted for 61.4% of therapies in the first six months of 2023, up from 2019, where these two drugs were prescribed 54.9%. CONCLUSION: Within this analysis, we provide an illustrative representation of the prescribing trends for PPIs within a European context. Omeprazole, rabeprazole and lansoprazole appear to be the cheapest drugs compared to pantoprazole and esomeprazole. However, the results show that the most widely used PPIs, despite their therapeutic equivalence, are precisely the high-cost ones, thus generating higher expenditure for central governments.

RESUMO

The use of monitoring registers with annexed negotiation agreements (MEAs) of the Italian Medicines Agency (AIFA) are the pillar of Italian healthcare governance to guarantee the correct allocation of economic healthcare resources. In Italy, an analysis was conducted in the context of a local health authority where all negotiation activities were implemented to verify the amount of reimbursements that can be recovered through the use of all available procedures on the monitoring registers. The purpose of this analysis was to highlight any criticalities which, if not properly addressed by doctors and pharmacists, can lead to considerable financial loss. Correct verification by the hospital pharmacy resulted in an economic recovery of approximately EUR 579,443.40 for the year 2022 and EUR 682,225.30 in the first 9 months of 2023. This analysis is intended to highlight how effective collaboration between doctors and pharmacists can lead to clear economic advantages with an efficient health system to the total benefit of citizens.

RESUMO

Approximately, 15% of global breast cancer cases are diagnosed as triple-negative breast cancer (TNBC), identified as the most aggressive subtype due to the simultaneous absence of estrogen receptor, progesterone receptor, and HER2. This characteristic renders TNBC highly aggressive and challenging to treat, as it excludes the use of effective drugs such as hormone therapy and anti-HER2 agents. In this review, we explore standard therapies and recent emerging approaches for TNBC, including PARP inhibitors, immune checkpoint inhibitors, PI3K/AKT pathway inhibitors, and cytotoxin-conjugated antibodies. The mechanism of action of these drugs and their utilization in clinical practice is explained in a pragmatic and prospective manner, contextualized within the current landscape of standard therapies for this pathology. These advancements present a promising frontier for tailored interventions with the potential to significantly improve outcomes for TNBC patients. Interestingly, while TNBC poses a complex challenge, it also serves as a paradigm and an opportunity for translational research and innovative therapies in the field of oncology.

RESUMO

p53 tumour suppressor gene is our major barrier against neoplastic transformation. It is involved in many cellular functions, including cell cycle arrest, senescence, DNA repair, apoptosis, autophagy, cell metabolism, ferroptosis, immune system regulation, generation of reactive oxygen species, mitochondrial function, global regulation of gene expression, miRNAs, etc. Its crucial importance is denounced by the high percentage of amino acid sequence identity between very different species (Homo sapiens, Drosophila melanogaster, Rattus norvegicus, Danio rerio, Canis lupus familiaris, Gekko japonicus). Many of its activities allowed life on Earth (e.g., repair from radiation-induced DNA damage) and directly contribute to its tumour suppressor function. In this review, we provide paramount information on p53, from its discovery, which is an interesting paradigm of science evolution, to potential clinical applications in anti-cancer treatment. The description of the fundamental biology of p53 is enriched by specific information on the structure and function of the protein as well by tumour/host evolutionistic perspectives of its role.
