Antimicrobial resistance refers to the ability of pathogens to develop resistance to drugs designed to eliminate them, making the infections they cause more difficult to treat and increasing the likelihood of disease diffusion and mortality. As such, antimicrobial resistance is considered as one of the most significant and universal challenges to both health and society, as well as the environment. In our research, we employ the explainable artificial intelligence paradigm to identify the factors that most affect the onset of antimicrobial resistance in diversified territorial contexts, which can vary widely from each other in terms of climatic, economic and social conditions.

Background: The use of magnetic resonance (MR) imaging for proton therapy treatment planning is gaining attention as a highly effective method for guidance. At the core of this approach is the generation of computed tomography (CT) images from MR scans. However, the critical issue in this process is accurately aligning the MR and CT images, a task that becomes particularly challenging in frequently moving body areas, such as the head-and-neck.

Article Synopsis
  • Intraductal oncocytic papillary neoplasms (IOPNs) are now identified as distinct from intraductal papillary mucinous neoplasms (IPMNs), with limited information on their recurrence and survival outcomes.
  • A study analyzed outcomes of 415 patients with invasive IOPNs and adenocarcinoma from IPMN over a median of 6 years, finding similar recurrence rates between invasive IOPNs and ductal A-IPMN, but poorer survival compared to colloid A-IPMN.
  • The research concluded that invasive IOPNs behave like aggressive cancers, with adjuvant chemotherapy showing no significant impact on recurrence rates in any of the studied cancer types.

Identifying the origin of a food product holds paramount importance in ensuring food safety, quality, and authenticity. Knowing where a food item comes from provides crucial information about its production methods, handling practices, and potential exposure to contaminants. Machine learning techniques play a pivotal role in this process by enabling the analysis of complex data sets to uncover patterns and associations that can reveal the geographical source of a food item.

Respiratory system cancer, encompassing lung, trachea and bronchus cancer, constitute a substantial and evolving public health challenge. Since pollution plays a prominent cause in the development of this disease, identifying which substances are most harmful is fundamental for implementing policies aimed at reducing exposure to these substances. We propose an approach based on explainable artificial intelligence (XAI) based on remote sensing data to identify the factors that most influence the prediction of the standard mortality ratio (SMR) for respiratory system cancer in the Italian provinces using environment and socio-economic data.

  • Patients undergoing pancreaticoduodenectomy for distal cholangiocarcinoma (dCCA) have a high recurrence rate, with 65% developing recurrence mostly within three years post-surgery.
  • The study identified common recurrence patterns, including local, distant, and mixed types, with primary sites being the pancreatic bed, liver, and lungs.
  • Key predictive factors for recurrence included cancer stage, type of surgical resection, and various histological features, helping inform potential follow-up treatments or strategies.

Respiratory malignancies, encompassing cancers affecting the lungs, the trachea, and the bronchi, pose a significant and dynamic public health challenge. Given that air pollution stands as a significant contributor to the onset of these ailments, discerning the most detrimental agents becomes imperative for crafting policies aimed at mitigating exposure. This study advocates for the utilization of explainable artificial intelligence (XAI) methodologies, leveraging remote sensing data, to ascertain the primary influencers on the prediction of standard mortality rates (SMRs) attributable to respiratory cancer across Italian provinces, utilizing both environmental and socioeconomic data.

  • A study was conducted to determine the effects of adjuvant chemotherapy on patients with adenocarcinoma from intraductal papillary mucinous neoplasia after surgical resection, analyzing data from 459 patients across 18 centers between 2010 and 2020.
  • The results showed that 59.9% of patients received various chemotherapy regimens, but there was no significant difference in recurrence rates or survival outcomes between those who received chemotherapy and those who did not.
  • Overall, the study concluded that adjuvant chemotherapy does not appear to improve recurrence patterns or survival rates in this patient population.

  • The study aimed to compare long-term cancer outcomes between patients with adenocarcinoma from intraductal papillary mucinous neoplasms (A-IPMN) and pancreatic ductal adenocarcinoma (PDAC) after surgical resection.
  • Data revealed that A-IPMN patients generally had better survival rates and lower recurrence rates compared to PDAC patients, including longer median survival (39.0 months for A-IPMN vs. 19.5 months for PDAC).
  • While A-IPMN showed higher rates of peritoneal and lung recurrence, PDAC had more locoregional recurrences, but overall, systemic recurrence rates were similar between the two groups.

Alzheimer's disease (AD) is the most common type of dementia with millions of affected patients worldwide. Currently, there is still no cure and AD is often diagnosed long time after onset because there is no clear diagnosis. Thus, it is essential to study the physiology and pathogenesis of AD, investigating the risk factors that could be strongly connected to the disease onset.

Liver transplantation (LT) was originally described by Starzl as a promising strategy to treat primary malignancies of the liver. Confronted with high recurrence rates, indications drifted towards non-oncologic liver diseases with LT finally evolving from a high-risk surgery to an almost routine surgical procedure. Continuously improving outcomes following LT and evolving oncological treatment strategies have driven renewed interest in transplant oncology.

Every year, 11% of infants are born preterm with significant health consequences, with the vaginal microbiome a risk factor for preterm birth. We crowdsource models to predict (1) preterm birth (PTB; <37 weeks) or (2) early preterm birth (ePTB; <32 weeks) from 9 vaginal microbiome studies representing 3,578 samples from 1,268 pregnant individuals, aggregated from public raw data via phylogenetic harmonization. The predictive models are validated on two independent unpublished datasets representing 331 samples from 148 pregnant individuals.

Correlation Plenoptic Imaging (CPI) is a novel volumetric imaging technique that uses two sensors and the spatio-temporal correlations of light to detect both the spatial distribution and the direction of light. This novel approach to plenoptic imaging enables refocusing and 3D imaging with significant enhancement of both resolution and depth of field. However, CPI is generally slower than conventional approaches due to the need to acquire sufficient statistics for measuring correlations with an acceptable signal-to-noise ratio (SNR).
