Machine learning to predict the decision to perform surgery in hepatic echinococcosis.

HPB (Oxford)

December 2024

Fondazione IRCCS Policlinico San Matteo, SC Chirurgia Generale 1, Pavia, Italy. Electronic address:

Background: Cystic echinococcosis (CE) is a significant public health issue, primarily affecting the liver. While several management strategies exist, there is a lack of predictive tools to guide surgical decisions for hepatic CE. This study aimed to develop predictive models to support surgical decision-making in hepatic CE, enhancing the precision of patient allocation to surgical or non-surgical management pathways.

Background/objectives: Algorithms for quantifying liver fat content based on the ultrasound attenuation coefficient (AC) are currently available; however, little is known about whether their accuracy increases by applying quality criteria such as the interquartile range-to-median ratio (IQR/M) or whether the median or average AC value should be used.

Methods: AC measurements were performed with the Aplio i800 ultrasound system using the attenuation imaging (ATI) algorithm (Canon Medical Systems, Otawara, Tochigi, Japan). Magnetic resonance imaging proton density fat fraction (MRI-PDFF) was the reference standard.

August 2024

Centro Regionale di Coordinamento della Medicina di Laboratorio, Milan, Italy.

Objective: Digital pathology is an opportunity to revise the routine and old artisanal workflow, moving to standard operating procedures, quality control and reproducibility. Here the results of a survey promoted by the Coordinamento della Medicina di Laboratorio (CRC Med Lab) of the Lombardy region in Italy are reported to shed light on the current situation of digital adoption in the country.

Methods: The survey composed of 58 questions was sent to 60 pathology laboratories.

Article Synopsis
  • Aldehyde dehydrogenases of the 1A subfamily (ALDH1A) are key enzymes that convert retinal into retinoic acid (RA), which is crucial for various bodily functions including development, reproduction, and immune response.* -
  • ALDH1A3, a specific isoform of ALDH1A, plays a significant role in cancers like glioblastoma multiforme and mesothelioma, where its levels are linked to poor patient prognosis due to increased tumor growth and resistance to treatment.* -
  • Recent research is focused on creating selective inhibitors for ALDH1A3 as a cancer therapy and developing specific fluorescent markers for better surgical resection of tumors.*

Article Synopsis
  • The study investigates how the backscatter coefficient (BSC) in ultrasound measurements of the liver changes with depth, similar to how the attenuation coefficient (AC) does.
  • Using a Sequoia ultrasound system, researchers analyzed data from 104 individuals, adjusting for factors like age, sex, and skin-to-liver-capsule distance.
  • The results revealed that BSC decreases significantly with depth (around -13.98 dB/cm-steradian per cm), suggesting a need for a standardized protocol to improve measurement consistency and reliability over time.

Article Synopsis
  • - This study conducts a meta-analysis to create a new grading system for liver steatosis using ultrasonography-based 2D-attenuation imaging (ATI), addressing the need for noninvasive tools in diagnosing liver disease.
  • - Eleven studies with 1374 patients revealed that ATI correlates strongly with histological and MRI-PDFF-confirmed steatosis, allowing for classification into four grades (S0 to S3) based on specific ATI measurements.
  • - The newly developed ATI grading system demonstrates high accuracy in determining liver steatosis, validated with independent patient cohorts and showing strong correlation with existing diagnostic methods.

Objectives: To assess whether meal or water intake may affect the measurement of the ultrasound (US) attenuation coefficient (AC) imaging, a parameter that is directly related to liver fat content.

Methods: The study was performed in two centers (Italy and USA). AC was obtained using the ATI algorithm implemented in the Aplio i-series US systems (Canon Medical Systems, Japan) by one operator at each center.

Despite advances in their diagnosis and treatment, pediatric cancers remain among the leading causes of death in childhood. The development of immunotherapies and other forms of targeted therapies has significantly changed the prognosis of some previously incurable cancers in the adult population. However, so far, the results in pediatric cohorts are disappointing, which is mainly due to differences in tumor biology, including extreme heterogeneity and a generally low tumor mutational burden.

[Proposal to improve the patient journey for women's cardiovascular prevention].

G Ital Cardiol (Rome)

March 2024

Fondazione Onda - Osservatorio Nazionale sulla Salute della Donna e di Genere.

The relevance of gender medicine in cardiovascular prevention is still underestimated, and there is a lack of viable women-specific preventive, diagnostic, and therapeutic strategies. To ensure women have equal access to cardiovascular prevention, cardiovascular disease risk stratification needs to consider gender-specific factors related to women reproductive cycle phases together with the different impact that traditional risk factors have on men and women. The aim of this document is to improve the patient journey for cardiovascular risk prevention in women, enhancing the importance of a multidisciplinary approach and the role of the various professional figures involved, starting with the general practitioner, as the main actor of the first risk stratification.

Purpose: To investigate whether intensive follow-up (INT) after surgery for endometrial cancer impact health-related quality of life (HRQoL) and healthcare costs compared to minimalist follow-up (MIN), in the absence of evidence supporting any benefit on 5-year overall survival.

Methods: In the TOTEM trial, HRQoL was assessed using the SF-12 and the Psychological General Well-Being (PGWB) questionnaires at baseline, after 6 and 12 months and then annually up to 5 years of follow-up. Costs were analyzed after 4 years of follow-up from a National Health Service perspective, stratified by risk level.

One-year surveillance for hypervirulent detected carbapenem-resistant superbugs.

Hypervirulent (hvKp) can cause infections in clinically healthy people, such as young and immunocompetent patients. Genes involved in the capsule synthesis or those encoding the siderophores have been adopted as predictors of hvKp. Certain sequence types, such as ST23 and ST86, have been associated with hvKp strains, too.

Quantitative MRI and ultrasound biomarkers of liver fibrosis have become important tools in the diagnosis and clinical management of children with chronic liver disease (CLD). In particular, MR elastography is now routinely performed in clinical practice to evaluate the liver for fibrosis. Ultrasound shear-wave elastography has also become widely performed for this purpose, especially in young children.

Background: There is much discussion in the literature about the link between traumatic events related to war and mental illness. However, in comparison, mental health has been more researched than protective factors such as coping methods, which are the primary factors to build resilience in these circumstances. This review examines the psychological and environmental elements that influence the resilience of Ukrainian refugees and IDPs by analyzing coping strategies and risk and protective factors.

Cystic formation in human primary brain tumors is a relatively rare event whose incidence varies widely according to the histotype of the tumor. Composition of the cystic fluid has mostly been characterized in samples collected at the time of tumor resection and no indications of the evolution of cystic content are available. We characterized the evolution of the proteome of cystic fluid using a bottom-up proteomic approach on sequential samples obtained from secretory meningioma (SM), cystic schwannoma (CS) and cystic high-grade glioma (CG).

U.O.C. Malattie Infettive I Fondazione IRCCS Policlinico San Matteo, Pavia, Italy.

Introduction: The hyperinflammation phase of severe SARS-CoV-2 is characterised by complete blood count alterations. In this context, the neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) can be used as prognostic factors. We studied NLR and PLR trends at different timepoints and computed optimal cutoffs to predict four outcomes: use of continuous positive airways pressure (CPAP), intensive care unit (ICU) admission, invasive ventilation and death.
