Objective: Prostate tumors, if prostate cancer or adenoma, represent a major public health challenge. Progress in research on inflammation has revealed a connection between inflammation, immunity, and cancer. In this context, this study aimed to find IL-6 signaling systemic abnormalities in the inflammatory tumor microenvironment.

Material and methods: This study was case-controlled, multicentered, and included 86 patients, 43 diagnosed with BPH and 43 diagnosed with PCa, between January 2019 and January 2020. The study group was homogenous and the studied parameters were IL-6 complex (IL-6, soluble receptor IL-6R, soluble glycoprotein gp130), acute phase proteins (C reactive protein-CRP, acid alpha1 glycoprotein-AGPA, ferritin, albumin, transferrin), and oxidative stress-associated variables (malondialdehyde-MDA, carbonylated protein-PCO, 8-hydroxy-deoxy guanosine-8-OHdG, total antioxidant status-bTAS).

Results: The inflammatory microenvironment determined IL-6 signaling alterations (over-regulation of sIL-6R and suppression of sgp130 in PCa versus BPH), changes in acute phase reaction markers (increased serum levels of CRP, AGPA, ferritin, and decreased serum levels of albumin, transferrin) that were much more evident in PCa compared to BPH, an imbalance between macromolecular oxidative damage (MDA, PCO, 8-OHdG) and endogenous antioxidants (TAS) that was more accentuated in PCa compared with BPH, and a representative association between the sIL-6R/sgp130 ratio and inflammatory/oxidative stress-related factors only in PCa patients.

Conclusions: Our study reconfirms the anterior concept that IL-6 promotes prostatic tumorigenesis. In this study, we first demonstrated that a high sIL-6R/sgp130 ratio facilitates prostate malignancy.

The preventability of acute lymphocytic leukemia during childhood is currently receiving great attention, as it is one of the most common cancers in children. Among the known risk factors so far are those affecting the development of gut microbiota, such as a short duration or absence of breastfeeding, cesarean section, a diet lacking in short-chain fatty acids (SCFAs), the use of antibiotics, absence of infection during infancy, and lack of pets, among other factors. Namely, it has been shown that iron deficiency anemia (IDA) and lack of vitamin D may cause intestinal dysbiosis, while at the same time, both increase the risk of hematological malignancies. The presence of IDA and vitamin D deficiency have been shown to lead to a decreased proportion of Firmicutes in stool, which could, as a consequence, lead to a deficit of butyrate. Moreover, children with IDA have increased blood concentrations of cadmium, which induces systemic inflammation and is linked to the onset of an inflammatory microenvironment in the bone marrow. Finally, IDA and Cd exposure increase fibroblast growth factor 23 (FGF23) blood levels, which in turn suppresses vitamin D synthesis. A lack of vitamin D has been associated with a higher risk of ALL onset. In brief, as presented in this review, there are three independent ways in which IDA increases the risk of acute lymphocytic leukemia (ALL) appearance. These are: intestinal dysbiosis, disruption of vitamin D synthesis, and an increased Cd load, which has been linked to systemic inflammation. All of the aforementioned factors could generate the appearance of a second mutation, such as ETV6/RUNX1 (TEL-AML), leading to mutation homozygosity and the onset of disease. ALL has been observed in both IDA and thalassemia. However, as IDA is the most common type of anemia and the majority of published data pertains to it, we will focus on IDA in this review.

Background and Objectives: The significance of periodontal disease as a public health issue prompts the exploration of effective treatments, including the potential use of tocopherol (Vitamin E) due to its anti-inflammatory and antioxidant properties. Materials and Methods: The PICO statement (Population, Intervention, Comparator, Outcome) was as follows: In patients with periodontal disease, does tocopherol (Vitamin E) supplementation compared to no supplementation or insufficient Vitamin E intake improve clinical outcomes such as gingival inflammation, pocket depth, and clinical attachment levels? This study searched through PubMed, Scopus, and Web of Science up to June 2024 focused on studies involving human subjects with various forms of periodontal disease, analyzing the impact of tocopherol through dietary or supplementary intake. Primary outcomes evaluated included improvements in gingival inflammation, pocket depth, and clinical attachment levels, with data synthesis conducted according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Quality assessment and risk of bias were meticulously performed for the included observational studies and randomized controlled trials. Results: The meta-analysis incorporated 8 studies that were used for data extraction, totaling 12,832 patients, revealing a heterogeneous response to tocopherol supplementation, with a pooled odds ratio for efficacy in reducing periodontal disease severity at about 0.97 (95% CI: 0.96-0.98). Noteworthy findings indicated a statistically significant increase in clinical attachment loss and pocket depth with odds ratios ranging from 1.15 to 9.33 when Vitamin E was insufficient. However, the considerable heterogeneity (I² = 88.35%) underscores variations in tocopherol's effectiveness across different populations and study designs. Conclusions: While tocopherol supplementation shows a modest benefit in managing periodontal disease, particularly in reducing clinical attachment levels and pocket depth, the variability in outcomes emphasizes the necessity for more research to establish standardized treatment protocols and dosages.

Background: The identification of women at high risk of breast cancer (BC) is crucial for personalized screening strategies. Pathogenic and likely pathogenic variants (PVs/LPVs) in susceptibility risk genes explain part of the individual risk. Moreover, a polygenic background, summarized as a polygenic risk score (PRS), contributes to the risk of BC and may modify the individual risk in carrier and non-carrier members of BC families.

Methods: We performed a retrospective pilot study evaluating PRS in women from a subset of high- (BRCA1 and BRCA2) and moderate-risk (PALB2 and ATM) BC families. We included PVs/LPVs carriers and non-carriers and evaluated a PRS based on 577,113 BC-associated variants. Using BOADICEA, we calculated the adjusted lifetime BC risk.

Results: Our data showed that in BRCA1/BRCA2 carriers, PVs have a major role in stratifying the lifetime risk, while PRS improves risk estimation in non-carriers of these families. A different scenario may be observed in PALB2 and ATM families where PRS combined with PV/LPV carrier status gives a more informative lifetime risk.

Conclusions: This study showed that in BC families, the PRS might help to quantify the weight of the genetic familial background, improving the individual risk stratification and contributing to personalized clinical management for carrier and non-carrier women.

Pharmacogenomic (PGx) testing can help personalise psychiatric prescribing and improve on the currently adopted trial-and-error prescribing approach. However, widespread implementation is yet to occur. Understanding factors influencing implementation is pertinent to the psychiatric PGx field. Normalisation Process Theory (NPT) seeks to understand the work involved during intervention implementation and is used by this review (PROSPERO: CRD42023399926) to explore factors influencing PGx implementation in psychiatry. Four databases were systematically searched for relevant records and assessed for eligibility following PRISMA guidance. The QuADS tool was applied during quality assessment of included records. Using an abductive approach to codebook thematic analysis, barrier and facilitator themes were developed using NPT as a theoretical framework. Twenty-nine records were included in the data synthesis. Key barrier themes included a PGx knowledge gap, a lack of consensus in policy and guidance, and uncertainty towards the use of PGx. Facilitator themes included an interest in PGx use as a new and improved approach to prescribing, a desire for a multidisciplinary approach to PGx implementation, and the importance of fostering a climate for PGx implementation. Using NPT, this novel review systematically summarises the literature in the psychiatric PGx implementation field. The findings highlight a need to develop national policies on using PGx, and an education and training workforce plan for mental health professionals. By understanding factors influencing implementation, the findings help to address the psychiatric PGx implementation gap. This helps move clinical practice closer towards a personalised psychotropic prescribing approach and associated improvements in patient outcomes. Future policy and research should focus on the appraisal of PGx implementation in psychiatry and the role of pharmacists in PGx service design, implementation, and delivery.

Background: Autism spectrum disorder (ASD) is related to social communication difficulties, repetitive behaviors, and highly restricted interests beginning early in life. Currently, ASD is more diagnosed than in the past, and new models are needed. The Advanced Integrative Model (AIM) is a new model in which genes and concomitant medical problems to diagnosis (CMPD) and the impact of their rigorous and adequate treatment are considered.

Methods: The role of a dynamic encephalopathy from which the individual response, susceptibilities in the brain and outside the brain, gut barrier and brain-blood-barrier permeabilities, and the plastic nature of the brain is proposed as a tool for diagnosis. The concomitant medical problems (CMP) are those at and outside the brain. The individual response to treatments of CMP is analyzed.

Results: The AIM allows for classification into 3 main groups and 24 subgroups.

Conclusions: The groups and subgroups in ASD are obtained taking into account CMPD treatments and individual response.

Background: This multicentric, retrospective study investigated the use of stereotactic body radiotherapy (SBRT) in patients (pts) with metastatic renal cell carcinoma (mRCC) who experienced oligoprogression during a combination therapy with an immune checkpoint inhibitor (ICI) and a tyrosine-kinase inhibitor (TKI).

Methods: We retrospectively evaluated 34 pts affected by oligoprogressive RCC treated with an ICI-TKI combination between January 2020 and December 2023. SBRT was delivered to each site of oligoprogressive metastatic disease. After SBRT, pts were given follow-up clinical evaluations. 6-12-18-month local control (LC) rates and median next-line treatment-free survival (NEST-FS) were the primary endpoints. The secondary endpoints were overall response rate (ORR), clinical benefits and safety.

Results: After a median follow-up of 24 months, 6-12-18-month LC rates were 100%, 71% and 43%, respectively, and the median NEST-FS was 20 months. ORR was 90%, while clinical benefit was 100%. No > G2 adverse events related to SBRT were recorded.

Conclusions: In our study, SBRT for oligoprogressive mRCC turned out to be a safe and useful treatment which was able to preserve current treatment. Further prospective studies are necessary to explore the effects of the ICIs-TKIs combination and SBRT upon oligoprogressive sites in mRCC.

Background: Distal bile duct cancer is an aggressive malignancy. Tumor-infiltrating immune cells (TIICs) in the tumor microenvironment are crucial for predicting prognosis in various cancers. In this study, we analyzed TIICs based on CD11b, CD163, and CD8 expression, and evaluated their association with clinicopathologic factors and prognosis in distal bile duct cancer. Methods: A total of 90 patients who underwent curative resection for distal bile duct cancer were enrolled. We analyzed CD11b+ tumor-infiltrating myeloid cells (TIMs), CD163+ tumor-infiltrating macrophages (TAMs), and CD8+ tumor-infiltrating lymphocytes (TILs) using immunohistochemistry and tissue microarrays. The correlation between TIICs and clinicopathologic characteristics was assessed. Results: Low levels of CD11b+ TIMs (p < 0.001) and high levels of CD8+ TILs (p = 0.003) were significantly associated with improved overall survival (OS). A combined low level of CD11b+ TIMs and high level of CD8+ TILs was identified as an independent favorable prognostic factor (hazard ratio, 0.159; confidence interval, 0.061-0.410; p < 0.001). Conclusions: CD11b+ TIMs play a crucial role in the tumor microenvironment and the prognosis of distal bile duct cancer. The combined analysis of CD11b+ TIMs and CD8+ TILs can predict survival in patients with distal bile duct cancer.

Objectives: Thyroid eye disease (TED) treatment has been recently revolutionized with the approval of teprotumumab, a targeted insulin growth factor 1 receptor (IGF1R) inhibitor. To date, teprotumumab is the only FDA-approved drug for treating TED. In this article, we would like to temper the current enthusiasm around IGF1R inhibitors. Methods: critical review of the literature by independent academic practitioners. Results: several questions should be raised. First, "how an orphan drug has become a blockbuster with annual sales exceeding $1 billion?" Teprotumumab infusions are expensive, costing about USD 45,000 for one infusion and USD 360,000 for eight infusions in a 75 kg patient. Teprotumumab approval was based on two randomized clinical trials investigating active (clinical activity score ≥ 4) TED patients. Despite this, teprotumumab was approved by the FDA for "the treatment of TED" without distinguishing between active and inactive forms. The second question is as follows: "how can a new drug, compared only to a placebo, become the new standard without being compared to historically established gold standard medical or surgical treatments?" Teprotumumab has never been compared to other medical treatments in active TED nor to surgery in chronic TED. Up to 75% of patients may experience proptosis regression after treatment discontinuation. Finally, ototoxicity has emerged as a potentially devastating side effect requiring frequent monitoring. Investigation into the long-term side effects, especially in women of childbearing age, is also warranted. Conclusions: Teprotumumab is undoubtedly a major treatment option in TED. However, before prescribing a drug, practitioners should assess its benefit/risk ratio based on the following: (i) evidence-based medicine; (ii) their empirical experience; (iii) the cost/benefit analysis; (iv) the long-term outcomes and safety profile.

Introduction: The choice of prosthesis for vertebral body reconstruction (VBR) remains a controversial issue due to the lack of a reliable solution. The subsidence rate of the most commonly used titanium mesh cages (TMC) ranges from 42.5% to 79.7%. This problem is primarily caused by the differences in the elastic modulus between the TMC and bone. This review aims to summarize the clinical and radiological outcomes of new 3D-printed artificial vertebral bodies (3DP AVB). Methods: A literature search of PubMed, Scopus and Google Scholar was conducted to extract relevant studies. After screening the titles and abstracts, a total of 50 articles were selected for full-text analysis. Results: Preliminary data suggest fewer implant-related complications with 3DP AVB. Most comparative studies indicate significantly lower subsidence rates, reduced operation times and decreased intraoperative blood loss. However, the scarcity of randomized clinical trials and the high variability of the results warrant caution. Conclusion: Most literature data show an advantage of 3DP AVB in terms of the operation time, intraoperative blood loss and subsidence rate. However, long manufacturing times, high costs and regulatory issues are this technology's main drawbacks.
