FMECA methodology applied to two pathways in an orthopaedic hospital in Milan.
INTRODUCTION: Adverse events pose a challenge to medical management: they can produce mild or transient disabilities or lead to permanent disabilities or even death; preventable adverse events result from error or equipment failure. METHODS: IRCCS Istituto Ortopedico Galeazzi implemented a clinical risk management program in order to study the epidemiology of adverse events and to improve new pathways for preventing clinical errors: a risk management FMECA-FMEA pro-active analysis was applied either to an existing clinical support pathway or to a new process before its implementation. RESULTS: The application of FMEA-FMECA allowed the clinical risk unit of our hospital to undertake corrective actions in order to reduce the adverse events and errors on high-risk procedure used inside the hospitals

MIK2 is a candidate gene of the S-locus for sporophytic self-incompatibility in chicory (Cichorium intybus, Asteraceae)
The Cichorium genus offers a unique opportunity to study the sporophytic self-incompatibility (SSI) system, being composed of species characterized by highly efficient self-incompatibility (e.g., C. intybus) and complete self-compatibility (e.g., C. endivia). To this end, the chicory genome was used to map seven previously identified SSI locus-associated markers. The region containing the S-locus was therefore restricted to an similar to 4 M bp window on chromosome 5. Among the genes predicted in this region, MDIS1 INTERACTING RECEPTOR LIKE KINASE 2 (ciMIK2) was particularly promising as a candidate for SSI. Its ortholog in Arabidopsis (atMIK2) is involved in pollen-stigma recognition reactions, and its protein structure is similar to that of S-receptor kinase (SRK), a key component of the SSI system in the Brassica genus. The amplification and sequencing of MIK2 in chicory and endive accessions revealed two contrasting scenarios. In C. endivia, MIK2 was fully conserved even when comparing different botanical varieties (i.e., smooth and curly endive). In C. intybus, 387 polymorphic positions and 3 INDELs were identified when comparing accessions of different biotypes all belonging to the same botanical variety (i.e., radicchio). The polymorphism distribution throughout the gene was uneven, with hypervariable domains preferentially localized in the LRR-rich extracellular region, putatively identified as the receptor domain. The gene was hypothesized to be under positive selection, as the nonsynonymous mutations were more than double the synonymous ones (dN/dS = 2.17). An analogous situation was observed when analyzing the first 500 bp of the MIK2 promoter: no SNPs were observed among the endive samples, whereas 44 SNPs and 6 INDELs were detected among the chicory samples. Further analyses are needed to confirm the role of MIK2 in SSI and to demonstrate whether the 23 species-specific nonsynonymous SNPs in the CDS and/or the species-specific 10 bp-INDEL found in a CCAAT box region of the promoter are responsible for the contrasting sexual behaviors of chicory and endive

Breastfeeding Self-Efficacy: A Systematic Review of Psychometric Properties Using COSMIN
Background:
Breastfeeding self-efficacy has been proven to play a predictive role in enhancing breastfeeding initiation and continuation. Breastfeeding self-efficacy measurement tools have facilitated healthcare professionalsâ early identification and support of women at higher risk of early discontinuation of breastfeeding.
Research Aim:
The aim of this study was to assess the psychometric properties of breastfeeding self-efficacy measurement tools.
Method:
A systematic review was carried out in three phases. Phase One comprised a systematic literature review performed in PubMed, SCOPUS, Web of Science, and Cochrane Database of Systematic Reviews from February 2021 to January 2023, including 36 studies for final analysis. Phase Two provided a quality appraisal of the psychometric properties of each of the seven breastfeeding self-efficacy measurement tools, according to COnsensus-based Standards for the selection of health Measurement Instrument checklist (COSMIN) guidelines. Phase Three summarized and graded the overall quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) modified approach.
Result:
The included articles comprised 9,225 participants and seven breastfeeding self-efficacy measurement tools. The Breastfeeding Self-Efficacy Scale, Breastfeeding Self-Efficacy Scale â Short Form (BSES-SF), and Prenatal Breastfeeding Self-Efficacy Scale were supported by Grade A evidence sustaining their validity and reliability to assess breastfeeding self-efficacy in the continuum of maternity care. The BSES-SF is the most feasible tool in clinical practice and the most utilized internationally, available in 15 languages.
Conclusion:
This systematic review provided a Grade A recommendation on breastfeeding measurement tools that will be helpful both for clinical and research purposes
Assessment of the Psychometric Characteristics of the Italian Version of the Nurse Manager Actions Scale
Nurse managers play a vital role in healthcare organizations, wielding the ability to substantially enhance work environments, foster nursesâ autonomy, and bolster retention within workplaces. In this context, this study focuses on the Nurse Manager Actions scale, aiming to evaluate its itemsâ scalability as well as the scaleâs validity and reliability among nurses and nurse managers operating within the Italian healthcare context. The study protocol was not registered. To ensure linguistic and cultural alignment, an iterative and collaborative translation process was undertaken. Subsequently, a multi-center cross-sectional design was adopted. Using a web-survey approach, data were collected among 683 nurses and 188 nurse managers between August 2022 and January 2023. The Nurse Manager Actions scale was found to be a valid and reliable instrument in Italian after a Mokken Scale Analysis. For nurses (HT = 0.630, MolenaarâSijtsma rho = 0.890), the scale included 6 items, while 11 items were confirmed for nurse managers (HT = 0.620, MolenaarâSijtsma rho = 0.830). Nurse Manager Actions scale scores were correlated with increased satisfaction and decreased intention to leave for both nurses and nurse managers. The employed validation process enhanced the scale validity for use in Italy and provided a model for other researchers to follow when assessing similar measures in different populations. Measuring and empowering nurse manager actions in work contexts is essential to improve the general well-being and retention of nurses, especially in the current nursing shortage
Peroxidasin protein expression and enzymatic activity in metastatic melanoma cell lines are associated with invasive potential
Peroxidasin, a heme peroxidase, has been shown to play a role in cancer progression. mRNA expression has been reported to be upregulated in metastatic melanoma cell lines and connected to the invasive phenotype, but little is known about how peroxidasin acts in cancer cells. We have analyzed peroxidasin protein expression and activity in eight metastatic melanoma cell lines using an ELISA developed with an in-house peroxidasin binding protein. RNAseq data analysis confirmed high peroxidasin mRNA expression in the five cell lines classified as invasive and low expression in the three non-invasive cell lines. Protein levels of peroxidasin were higher in the cell lines with an invasive phenotype. Active peroxidasin was secreted to the cell culture medium, where it accumulated over time, and peroxidasin protein levels in the medium were also much higher in invasive than non-invasive cell lines. The only well-established physiological role of peroxidasin is in the formation of a sulfilimine bond, which cross-links collagen IV in basement membranes via catalyzed oxidation of bromide to hypobromous acid. We found that peroxidasin secreted from melanoma cells formed sulfilimine bonds in uncross-linked collagen IV, confirming peroxidasin activity and hypobromous acid formation. Moreover, 3-bromotyrosine, a stable product of hypobromous acid reacting with tyrosine residues, was detected in invasive melanoma cells, substantiating that their expression of peroxidasin generates hypobromous acid, and showing that it does not exclusively react with collagen IV, but also with other biomolecules

The Italian midwifery core outcome set (M-COS) for healthy childbearing women and newborns: Development and initial validation study
Objective
This study aimed to develop and validate a midwifery core outcome set (M-COS) for Italian settings based on a salutogenic framework of maternity care.
Design
A multi-phase and multi-method study was performed. In phase one, we conducted a literature review to identify a preliminary set of outcomes sensitive to midwifery care. In phase two, the qualitative and quantitative content validity of the M-COS was tested. Finally, in the third phase, construct validity was explored through a cross-sectional study to assess the psychometric properties of the M-COS through exploratory and confirmative factor analysis. This study was conducted from December 2019 to April 2020 in Italy.
Participants
Three main groups of experts/midwives were involved. Group One (n = 10) was involved in the content validity phase, while the other two groups (Group Two and Group Three) were involved in the construct validity phase (n = 300).
Results
The M-COS includes six outcome domains and thirty-one core outcomes perceived as sensitive to midwifery care, namely: mortality and morbidity (n = 6 outcomes), childbirth (n = 3), postnatal period (n = 6), maternal health (n = 11), maternal-infant bonding (n = 3), and maternal self-care (n = 2). All domains showed good evidence of internal consistency.
Conclusion
The Italian M-COS is a novel tool that will facilitate the consistent measurement of core outcomes sensitive to midwifery care from the antenatal to the postnatal period in Italian settings. This initial work will be followed by further studies, including validation by service users.
Implications for practice
The use of the M-COS in clinical practice would facilitate evidence-based data collection and thus contribute to promoting high-quality maternity care

Developmental Strategy and Validation of the Midwifery Interventions Classification (MIC): A Delphi Study Protocol and Results from the Developmental Phase
This study protocol aims to describe the rationale and developmental strategy of the first study in the Italian context which aimed to define a Midwifery Interventions Classification, an evidence-based, standardized taxonomy and classification of midwifery interventions. Midwifery interventions require a specific definition, developed through a consensus-building process by stakeholders to develop the Italian taxonomy of the Midwifery Interventions Classification with the potential for international transferability, implementation, and scaling up. A multi-round Delphi study was designed between June and September 2022, and data collection is planned between February 2023 and February 2024. The developmental phase of the study is based on a literature review to select meaningful midwifery interventions from the international literature, aiming to identify an evidence-based list of midwifery interventions. This phase led to including 16 articles derived from a systematic search performed on PubMed, CINAHL, and Scopus; 164 midwifery interventions were selected from the data extraction performed on the 16 included articles. Healthcare professionals, researchers, and service users will be eligible panelists for the Delphi surveys. The protocol designed a dynamic number of consultation rounds based on the ratings and interim analysis. A nine-point Likert scoring system is designed to evaluate midwifery interventions. Attrition and attrition bias will be evaluated. The results from the study designed in this protocol will inform the development of the Italian taxonomy of the Midwifery Interventions Classification. A shared classification of midwifery interventions will support audit and quality improvement, education, and comparable data collections for research, sustaining public recognition of midwifery interventions to promote optimal maternal and newborn health
