Impact of an autonomous delivery robot on sample turnaround time in a clinical laboratory: an early evaluation of first implementation Jacopo Gervasoni, Davide Pedrazzini, Michela Cicchinelli, Silvia Persichilli, Silvia Baroni, Sandro Rocchetti, Giovanni Arcuri, Andrea Urbani Clinical Chemistry and Laboratory Medicine, 2026 Objectives The aim of this study was to evaluate the impact of introducing an autonomous courier in a clinical laboratory, focusing on specimen turnaround time (TAT). We assessed whether high-frequency robotic transport from the central accessioning area to analytical sections could reduce delays and variability compared with manual delivery. Methods We retrospectively analyzed routine lithium–heparin glucose specimens processed during the initial days of robot deployment (13–23 May 2025, weekdays, 08:00–16:00) and compared them with the same period in 2024 under manual transport. TAT was defined as the interval from check-in at accessioning to technical validation in the Laboratory Information System (LIS). Data were assessed globally and stratified by time of day, examining changes in central tendency, dispersion, and extreme delays. Results In total, 6,299 samples in 2024 and 5,759 in 2025 were analyzed, showing a leftward shift of the distribution with fewer delay. In 2025, the mean TAT decreased from 122.64 to 106.72 min, the median from 112 to 101 min, and dispersion tightened. Stratification by time of day also demonstrated consistent improvements. Conclusions Even in its earliest days of operation, the delivery robot reduced TAT and variability, converting specimen transport from batch runs into near-continuous flow. These findings highlight ease of adoption and the potential of robotic transport to improve speed, predictability, and safety in intralaboratory logistics. Further validation across longer periods and additional laboratory sections is warranted.
Development of a novel Ultra Performance Liquid Chromatography Tandem-Mass Spectrometry (UPLC-MS/MS) method to measure L-arginine metabolites in plasma Lavinia Santucci, Sara Lomuscio, Aniello Primiano, Riccardo Calvani, Silvia Persichilli, Federica Iavarone, Anna Picca, Francesca Canu, Andrea Urbani, Jacopo Gervasoni Clinica Chimica Acta, 2023 INTRODUCTION: Arginine metabolism is involved in the regulation of several biological processes. Many liquid chromatography tandem-mass spectrometry methods for the determination of arginine and its metabolites have been developed but they are time consuming and imply long pre-analytical procedures. The purpose of this study was to develop a rapid method for the simultaneous determination of arginine, citrulline, ornithine, symmetric and asymmetric dimethylarginine and monomethylarginine in human plasma. MATERIALS AND METHODS: The pre-analytical procedure consisted in a simple deproteinization. The chromatographic separation was performed using hydrophilic interaction liquid chromatography. Analytes detection was performed with a triple quadrupole equipped with electrospray ion source operating in positive ion mode. Mass spectrometry experiments were conducted in multiple reaction monitoring mode. RESULTS AND CONCLUSIONS: Recovery ranged from 92.2 to 108.0%. The within-run imprecision and between-run imprecision ranged from 1.5 to 6.8 % and 3.8 to 11.9%, respectively. Carry over and matrix effect did not affect quantitative analysis. Extraction recovery was between 95 and 105 %. Stability after pre-analytical procedure was tested and all the metabolites were stable after 48 h at 4 °C. In conclusion, our novel method allow a rapid and easy determination of arginine and its metabolites both for research and clinical routine use.
Intestinal Permeability and Dysbiosis in Female Patients with Recurrent Cystitis: A Pilot Study Cristina Graziani, Lucrezia Laterza, Claudia Talocco, Marco Pizzoferrato, Nicoletta Di Simone, Silvia D’Ippolito, Caterina Ricci, Jacopo Gervasoni, Silvia Persichilli, Federica Del Chierico, Valeria Marzano, Stefano Levi Mortera, Aniello Primiano, Andrea Poscia, Francesca Romana Ponziani, Lorenza Putignani, Andrea Urbani, Valentina Petito, Federica Di Vincenzo, Letizia Masi, Loris Riccardo Lopetuso, Giovanni Cammarota, Daniela Romualdi, Antonio Lanzone, Antonio Gasbarrini, Franco Scaldaferri Journal of Personalized Medicine, 2022 Recurrent cystitis (RC) is a common disease, especially in females. Anatomical, behavioral and genetic predisposing factors are associated with the ascending retrograde route, which often causes bladder infections. RC seems to be mainly caused by agents derived from the intestinal microbiota, and most frequently by Escherichia coli. Intestinal contiguity contributes to the etiopathogenesis of RC and an alteration in intestinal permeability could have a major role in RC. The aim of this pilot study is to assess gut microbiome dysbiosis and intestinal permeability in female patients with RC. Patients with RC (n = 16) were enrolled and compared with healthy female subjects (n = 15) and patients with chronic gastrointestinal (GI) disorders (n = 238). We calculated the Acute Cystitis Symptom Score/Urinary Tract Infection Symptom Assessment (ACSS/UTISA) and Gastrointestinal Symptom Rating Scale (GSRS) scores and evaluated intestinal permeability and the fecal microbiome in the first two cohorts. Patients with RC showed an increased prevalence of gastrointestinal symptoms compared with healthy controls. Of the patients with RC, 88% showed an increased intestinal permeability with reduced biodiversity of gut microbiota compared to healthy controls, and 68% of the RC patients had a final diagnosis of gastrointestinal disease. Similarly, GI patients reported a higher incidence of urinary symptoms with a diagnosis of RC in 20%. Gut barrier impairment seems to play a major role in the pathogenesis of RC. Further studies are necessary to elucidate the role of microbiota and intestinal permeability in urinary tract infections.

Folic acid and autism: A systematic review of the current state of knowledge Bianka Hoxha, Malvina Hoxha, Elisa Domi, Jacopo Gervasoni, Silvia Persichilli, Visar Malaj, Bruno Zappacosta Cells, 2021 Folic acid has been identified to be integral in rapid tissue growth and cell division during fetal development. Different studies indicate folic acid’s importance in improving childhood behavioral outcomes and underline its role as a modifiable risk factor for autism spectrum disorders. The aim of this systematic review is to both elucidate the potential role of folic acid in autism spectrum disorders and to investigate the mechanisms involved. Studies have pointed out a potential beneficial effect of prenatal folic acid maternal supplementation (600 µg) on the risk of autism spectrum disorder onset, but opposite results have been reported as well. Folic acid and/or folinic acid supplementation in autism spectrum disorder diagnosed children has led to improvements, both in some neurologic and behavioral symptoms and in the concentration of one-carbon metabolites. Several authors report an increased frequency of serum auto-antibodies against folate receptor alpha (FRAA) in autism spectrum disorder children. Furthermore, methylene tetrahydrofolate reductase (MTHFR) polymorphisms showed a significant influence on ASD risk. More clinical trials, with a clear study design, with larger sample sizes and longer observation periods are necessary to be carried out to better evaluate the potential protective role of folic acid in autism spectrum disorder risk.
Investigating different forms of hydrogen sulfide in cerebrospinal fluid of various neurological disorders Viviana Greco, Cristina Neri, Damiana Pieragostino, Alida Spalloni, Silvia Persichilli, Matteo Gastaldi, Nicola B. Mercuri, Patrizia Longone, Andrea Urbani Metabolites, 2021 Over the past 30 years a considerable amount of data has accumulated on the multifaceted role of hydrogen sulfide (H2S) in the central nervous system. Depending on its concentrations, H2S has opposite actions, ranging from neuromodulator to neurotoxic. Nowadays, accurate determination of H2S is still an important challenge to understand its biochemistry and functions. In this perspective, this study aims to explore H2S levels in cerebrospinal fluid (CSF), key biofluid for neurological studies, and to assess alleged correlations with neuroinflammatory and neurodegenerative mechanisms. A validated analytical determination combining selective electrochemical detection with ion chromatography was developed to measure free and bound sulfur forms of H2S. A first cohort of CSF samples (n = 134) was analyzed from patients with inflammatory and demyelinating disorders (acute disseminated encephalomyelitis; multiple sclerosis), chronic neurodegenerative diseases (Alzheimer disease; Parkinson disease), and motor neuron disease (Amyotrophic lateral sclerosis). Given its analytical features, the chromatographic method resulted sensitive, reproducible and robust. We also explored low molecular weight-proteome linked to sulphydration by proteomics analysis on matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS). This study is a first clinical report on CSF H2S concentrations from neurological diseases and opens up new perspectives on the potential clinical relevance of H2S and its potential therapeutic application.
Ceramic-on-metal bearing in short stem total hip arthroplasty: ions, functional and radiographic evaluation at mid-term follow-up Michela Saracco, Giulio Maccauro, Andrea Urbani, Domenico Ciavardelli, Silvia Persichilli, Giulio Ancillai, Patrizio Pasqualetti, Vittorio Calvisi, Giandomenico Logroscino HIP International, 2020 Introduction: The aim of this study is to evaluate clinical, radiographic and laboratory results of ceramic-on-metal (CoM) (hybrid hard bearing) in total hip arthroplasty (THA), associated with a short stem implant. Methods: From a cohort of 37 patients suffering from primary or secondary hip osteoarthritis who underwent THA using CoM bearing, 19 were suitable for this study. All procedures were performed by the same surgeon using a posterior-lateral approach. All patients were compared clinically using the Harris Hip Score (HHS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analogue scale (VAS), 12-item Short Form Health Survey (SF12F/M), and radiographically (offset, CD angle, limb length discrepancy, cup inclination and anteversion, subsidence, osseointegration, heterotopic ossification). Blood samples were collected in order to evaluate chromium (Cr) and cobalt (Co) ions level. Radiographic evaluations were carried out by 3 different blinded surgeons. A statistical analysis was performed. Results: At a mean follow-up of 97 (73–125) months all implanted stems were well-positioned and osseointegrated. Clear improvements were observed for clinical scores comparing preoperative and postoperative values. Radiographic evaluation showed a good ability to restore proper articular geometry. Cr ion analysis revealed values below the safety threshold except for 1 case. Serum levels of Co were below the threshold in all patients. There was a statistically significant correlation only between Cr metal ions and length of follow-up. Conclusions: CoM bearing has proven to be reliable and safe at a mean 8-year follow-up for patients in whom the components were correctly implanted. The rise of blood metal ions was minimal and involved neither systemic or local toxicity nor influenced clinical results.
