RESUMO

PURPOSE: This systematic review aimed to investigate the therapeutic relationship (TR) between mental health professionals (MHPs) and their patients in community mental health services (CMHS). METHODS: PubMed (Medline), PsycINFO, CINAHL, CENTRAL, and Web of Science were searched for studies that assessed TR in CMHS using quantitative measures developed specifically for this setting (i.e., Helping Alliance Scale [HAS] and the Scale to Assess the Therapeutic Relationship [STAR]). Studies were included if they considered adult patients with a psychiatric disorder and/or any MHP working in CMHS. Meta-analysis and narrative synthesis assessed the association between patients' and MHPs' ratings and identified predictors of TR. RESULTS: Of 1934 studies, 15 were included in the review, including 3004 patients. A total of 1127 patients and 963 MHPs were considered in the meta-analysis. The heterogeneity of the studies was high, and there was no significant difference between the patients' and MHPs' TR ratings in the random-effects model (standardized mean difference [SMD]: - 0.39 [95% CI: - 1.03; 0.24]). In the multivariable meta-regression, only duration of illness was significantly associated with TR ratings (unstandardized regression coefficient [B]: 0.388 [95% CI: 0.217; 0.558]). A recovery-oriented service, shared decision-making, and the recognition of patient needs contributed to more positive TR ratings. CONCLUSION: Patients and MHPs converged in their TR ratings, although patients gave lower ratings. Routine assessment of TR in CMHS can inform reflective practice and service development, as TR can be assessed easily and early in the treatment process. Future research should focus on developing and testing interventions to improve TR in CMHS.

RESUMO

The Sda carbohydrate epitope and its biosynthetic B4GALNT2 enzyme are expressed in the healthy colon and down-regulated to variable extents in colon cancer. The human B4GALNT2 gene drives the expression of a long and a short protein isoform (LF-B4GALNT2 and SF-B4GALNT2) sharing identical transmembrane and luminal domains. Both isoforms are trans-Golgi proteins and the LF-B4GALNT2 also localizes to post-Golgi vesicles thanks to its extended cytoplasmic tail. Control mechanisms underpinning Sda and B4GALNT2 expression in the gastrointestinal tract are complex and not fully understood. This study reveals the existence of two unusual N-glycosylation sites in B4GALNT2 luminal domain. The first atypical N-X-C site is evolutionarily conserved and occupied by a complex-type N-glycan. We explored the influence of this N-glycan using site-directed mutagenesis and showed that each mutant had a slightly decreased expression level, impaired stability, and reduced enzyme activity. Furthermore, we observed that the mutant SF-B4GALNT2 was partially mislocalized in the endoplasmic reticulum, whereas the mutant LF-B4GALNT2 was still localized in the Golgi and post-Golgi vesicles. Lastly, we showed that the formation of homodimers was drastically impaired in the two mutated isoforms. An AlphaFold2 model of the LF-B4GALNT2 dimer with an N-glycan on each monomer corroborated these findings and suggested that N-glycosylation of each B4GALNT2 isoform controlled their biological activity.

RESUMO

Background and Objectives: ADHD is a neurodevelopmental disorder characterized by inattention and hyperactivity/impulsivity and can persist in adulthood. The aim of this study is to deepen knowledge about adult ADHD follow-up. Materials and Methods: This observational study consists of one retrospective part aimed at collecting records of children and adolescents treated for ADHD in the Children and Adolescent Mental Health Service (CAMHS) from 1995 to 2015 and, successively, at identifying their adult follow-up in Adult Mental Health Service (AMHS); the second part consists of ADHD scale administration, Diagnostic Interview for ADHD in Adults (DIVA 2-0) and Adult Self Rating Scale (ASRSv1.1), for the subjects currently being treated at AMHS who agreed to participate in the study. Results: We observed that among the 55 patients treated at CAMHS between 1995 and 2015 for ADHD and subsequently at the AMHS, none presented a diagnosis of ADHD; instead, they were treated for Intellectual Dysfunction (33%), Borderline Personality Disorder (15%) and Anxiety Disorders (9%), and two individuals were also diagnosed with comorbid substance/alcohol abuse (4%). Of the 55 patients, only 25 (45%) were treated at AMHS during the study period. Though we asked for their informed consent to administer the questionnaires, we were able to test only seven patients. The ASRS-V1.1 score showed that 43% of patients reported symptoms of ADHD persistence in adulthood. For DIVA 2.0, 57% of individuals reported scores indicating the persistence of the ADHD inattention component, and 43% the persistence of both ADHD dimensions. Conclusions: ADHD cannot be considered a disorder confined to childhood/adolescence but instead is a chronic and complex condition that can persist into adulthood. The very small size of our final sample may account for both the high ADHD dropout rate over the long follow-up period and the difficult transition from child to adult health care in ADHD treatment. Our investigation suggests the need for specific training in the diagnosis and treatment of adult ADHD and the implementation of transition protocols between minor and adult services to improve long-term treatments.

RESUMO

BACKGROUND: Patients with COVID-19 experience multiple clinical conditions that may cause electrolyte imbalances. Hypokalemia is a concerning electrolyte disorder closely associated with severe complications. This study aimed to estimate prevalence, risk factors and outcome of hypokalemia in a cohort of patients with confirmed COVID-19. METHODS: A retrospective analysis was conducted on 290 non-ICU admitted patients with COVID-19 at the tertiary teaching hospital of Modena, Italy, from February 16 to April 14, 2020. RESULTS: Hypokalemia was detected in 119 out of 290 patients (41%) during hospitalization. Mean serum potassium was 3.1 ± 0.1 meq/L. The majority of patients (90.7%) patients experienced only a mild decrease in serum potassium level (3-3.4 mEq/L). Hypokalemia was associated with hypocalcemia, which was detected in 50% of subjects. Urine potassium-to-creatinine ratio, measured in a small number of patients (n = 45; 36.1%), revealed an increase of urinary potassium excretion in most cases (95.5%). Risk factors for hypokalemia were female sex (odds ratio (OR) 2.44; 95% CI 1.36-4.37; P 0.003) and diuretic therapy (OR 1.94, 95% CI 1.08-3.48; P 0.027). Hypokalemia, adjusted for sex, age and SOFA score, was not associated with ICU transfer (OR 0.52; 95% CI 0.228-1.212; P = 0.131), in-hospital mortality (OR, 0.47; 95% CI 0.170-1.324; P = 0.154) and composite outcome of ICU transfer or in-hospital mortality (OR 0.48; 95% CI 0.222-1.047; P = 0.065) in our cohort of patients. CONCLUSIONS: Hypokalemia was a frequent disorder in subjects with COVID-19. Female sex and diuretic therapy were identified as risk factors for low serum potassium levels. Hypokalemia was unrelated to ICU transfer and death in this cohort of patients.

RESUMO

BACKGROUND: Caregivers of patients load different kinds of burdens, including emotional distress. Aims of this study were to evaluate both burden and empathy of caregivers who assist patients with schizophrenia spectrum disorders. METHODS: We selected a sample of 60 caregivers (34 women and 26 men), who assisted patients with schizophrenia spectrum disorders treated in our local Community Mental Health Center for a 1-year minimum period. We administered two scales to our sample, Zarit Burden Interview (ZBI) and Balanced Emotional Empathy Scale (BEES), and collected data of caregivers and their assisted patients in a 3-month period. Data were statistically analyzed. RESULTS: We reported a mean ZBI score of 49.68 (±15.03 SD) and a mean BEES score of 14.35 (±9.05 SD), indicating the perception of moderate-severe burden and low level of empathy, respectively. The analysis of internal consistency confirmed the good reliability of both ZBI (Cronbach's alpha = 0.90) and BEES (Cronbach's alpha = 0.77). The correlation between the two scales was not statistically significant at Spearman test. At our multiple linear regression, many variables of both caregiver and patient showed a significant correlation with the ZBI score. In particular, not living with the assisted patient and female gender of caregiver potentially decreased the burden, whereas clinical severity of assisted patient and two caregiver conditions, middle school education and spouse relationship with patient, could worsen the burden. We highlighted two positive statistically significant correlations between the total score of BEES and caregiver characteristics: being spouse and not living with assisted patient. CONCLUSIONS: Our study highlights that the caregiver burden of patients with severe psychiatric disorders is high and is associated with low emotional empathy experienced by caregivers, probably due to a defensive psychological mechanism. The conditions of spouse and cohabitation can concomitantly increase both empathy and burden in caregivers.

RESUMO

OBJECTIVES: to analyse the association between smoking behaviour and economic crises in Italy between 1993 and 2015. DESIGN: ecological study, carried out on data of the Italian National Institute of Statistics, by means of fixed-effect panel regressions. SETTING AND PARTICIPANTS: the rate of smoking prevalence (disaggregated by gender and age) and the unemployment rate (disaggregated by gender and referring to individuals aged 15 or more) were collected for each of the twenty Italian regions. Also, percentage fluctuations of the national real gross domestic product (GDP) were collected to identify the years of severe economic crisis. MAIN OUTCOME MEASURES: number of people who smoke per 100 people with the same features. RESULTS: among men, increased regional unemployment rate was associated with increased smoking behaviour only in the group aged 25-34 years. Differently, severe economic crises were associated with increased smoking in almost all age groups, except for men aged 15-24 years. A 1-point decrease in GDP was associated with 0.75 more smokers aged 15 years or more. The highest coefficient was reported among men aged 35-44 years, where a 1-point decrease in GDP was associated with 1.16 more smokers (every 100 men). This age group is also featured by the second highest prevalence of tobacco smoking (36.8%). Among women, a 1-point increase in the regional unemployment rate was associated with 0.08 less smokers every 100 women. Similarly, periods of severe economic crisis at national level were associated with reduced smoking behaviour among women aged 15 years or more, specifically those aged 15-24 years. Differently, women aged 25-34 and 65 years or more showed an association similar to that reported among men. In these groups, a 1-point decrease in GDP was associated with 0.67 and 1.08 more smokers every 100 women. While among the latter the prevalence of tobacco smoking is the lowest, among the former it is the third highest prevalence (21.69%). Therefore, increased smoking behaviour due to economic crises seems to occur especially among women aged 25-35 years old, as happens among men. CONCLUSIONS: men in almost all age groups and women aged 25-34 and 65 years or more represent vulnerable groups in which smoking behaviour may increase in times of economic hardship. Therefore, specific policies should be implemented to prevent this occurrence, as well as the negative health outcomes of tobacco smoking.

RESUMO

Cancer-associated glycan structures can be both tumor markers and engines of disease progression. The structure Siaα2,6Galß1,4GlcNAc (Sia6LacNAc), synthesized by sialyltransferase ST6GAL1, is a cancer-associated glycan. Although ST6GAL1/Sia6LacNAc are often overexpressed in colorectal cancer (CRC), their biological and clinical significance remains unclear. To get insights into the clinical relevance of ST6GAL1 expression in CRC, we interrogated The Cancer Genome Atlas with mRNA expression data of hundreds of clinically characterized CRC and normal samples. We found an association of low ST6GAL1 expression with microsatellite instability (MSI), BRAF mutations and mucinous phenotype but not with stage, response to therapy and survival. To investigate the impact of ST6GAL1 expression in experimental systems, we analyzed the transcriptome and the phenotype of the CRC cell lines SW948 and SW48 after retroviral transduction with ST6GAL1 cDNA. The two cell lines display the two main pathways of CRC transformation: chromosomal instability and MSI, respectively. Constitutive ST6GAL1 expression induced much deeper transcriptomic changes in SW948 than in SW48 and affected different genes in the two cell lines. ST6GAL1 expression affected differentially the tyrosine phosphorylation induced by hepatocyte growth factor, the ability to grow in soft agar, to heal a scratch wound and to invade Matrigel in the two cell lines. These results indicate that the altered expression of a cancer-associated glycosyltransferase impacts the gene expression profile, as well as the phenotype, although in a cancer subtype-specific manner.

RESUMO

BACKGROUND: Treatment with Bacillus Calmette-Guérin (BCG) is the gold standard adjuvant immunotherapy of non-muscle invasive bladder cancer (NMIBC), although it fails in one third of the patients. NMIBC expresses two tumor-associated O-linked carbohydrates: the disaccharide (Galß1,3GalNAc) Thomsen-Friedenreich (T) antigen, and its sialylated counterpart (Siaα2,3Galß1,3GalNAc) sialyl-T (sT), synthesized by sialyltransferase ST3GAL1, whose roles in BCG response are unknown. METHODS: The human bladder cancer (BC) cell line HT1376 strongly expressing the T antigen, was retrovirally transduced with the ST3GAL1 cDNA or with an empty vector, yielding the cell lines HT1376sT and HT1376T, that express, respectively, either the sT or the T antigens. Cells were in vitro challenged with BCG. Whole gene expression was studied by microarray technology, cytokine secretion was measured by multiplex immune-beads assay. Human macrophages derived from blood monocytes were challenged with the secretome of BCG-challenged BC cells. RESULTS: The secretome from BCG-challenged HT1376sT cells induced a stronger macrophage secretion of IL-6, IL-1ß, TNFα and IL-10 than that of HT1376T cells. Transcriptomic analysis revealed that ST3GAL1 overexpression and T/sT replacement modulated hundreds of genes. Several genes preserving genomic stability were down-regulated in HT1376sT cells which, as a consequence, displayed increased sensitivity to oxidative damage. After BCG challenge, the transcriptome of HT1376sT cells showed higher susceptibility to BCG modulation than that of HT1376T cells. CONCLUSIONS: High ST3GAL1 expression and T/sT replacement in BCG challenged-BC cancer cells induce a stronger macrophage response and alter the gene expression towards genomic instability, indicating a potential impact on BC biology and patient's response to BCG.

RESUMO

Glycosylation is a very frequent and functionally important post-translational protein modification that undergoes profound changes in cancer. Growth and death factor receptors and plasma membrane glycoproteins, which upon activation by extracellular ligands trigger a signal transduction cascade, are targets of several molecular anti-cancer drugs. In this review, we provide a thorough picture of the mechanisms bywhich glycosylation affects the activity of growth and death factor receptors in normal and pathological conditions. Glycosylation affects receptor activity through three non-mutually exclusive basic mechanisms: (1) by directly regulating intracellular transport, ligand binding, oligomerization and signaling of receptors; (2) through the binding of receptor carbohydrate structures to galectins, forming a lattice thatregulates receptor turnover on the plasma membrane; and (3) by receptor interaction with gangliosides inside membrane microdomains. Some carbohydrate chains, for example core fucose and ß1,6-branching, exert a stimulatory effect on all receptors, while other structures exert opposite effects on different receptors or in different cellular contexts. In light of the crucial role played by glycosylation in the regulation of receptor activity, the development of next-generation drugs targeting glyco-epitopes of growth factor receptors should be considered a therapeutically interesting goal.

RESUMO

BACKGROUND: The triple-dip recession taking place in Italy in 2008-2014 impacted negatively on health, mainly by increasing the rate of unemployment. This increased the prevalence of mental health disorders, while reducing the number of available places on vocational rehabilitation programs (VRPs) delivered by the psychiatric services. OBJECTIVES: To explore the different points of views of stakeholders (namely, users and professionals) involved in VRPs developed inside an Italian Community Mental Health Center (CMHC). METHODS: A sample of users, psychiatrists, educators and nurses of an Italian CMHC involved in VRPs took part in a focus group. Content analysis was performed with MAXQDA 12, by developing a hierarchical code system a posteriori (i.e., derived from the data). The respondent validation phase was carried out by means of a multiple-choice questionnaire, administered to all participants. RESULTS: A total of 86 emerging issues were coded, divided into two macro-areas: Positive and Negative Reinforcements (48 contributions, 56%, and 38 contributions, 44%, respectively), further subdivided into three areas: professional (service) factors, personal (i.e, user-related) factors, and work environment features (including relationships in the workplace). Some contributions raised issues concerning occupational health protection (e.g. need of information about the rights and duties of the users-workers, as well as the risks they are exposed to in the workplace). CONCLUSIONS: The analysis suggested to address specific issues concerning work and VRPs by means of psycho-education group interventions currently carried out at CMHCs, and pointed to the need to foster collaboration between mental health professionals and the occupational health physician of the company where the VRP is started and where the user might be employed.

RESUMO

Deep level transient spectroscopy (DLTS) was performed on lowly n-doped silicon nanowires grown by metal-assisted wet chemical etching (MaWCE) with silver as the catalyst in order to investigate the energetic scheme inside the bandgap. To observe the possible diffusion of atoms into the bulk, DLTS investigation was also performed on the samples after removing the nanowires. Two of the four energy levels observed in the nanowires were also detected inside the substrate. Based on these results and on literature data about deep levels in bulk silicon, some hypotheses are advanced regarding the identification of the defects responsible for the energy levels revealed.

RESUMO

Deep level transient spectroscopy (DLTS) was performed on n-doped silicon nanowires grown by metal-assisted wet chemical etching (MaWCE) with gold as the catalyst in order to investigate the energetic scheme inside the bandgap. To observe the possible dependence of the level scheme on the processing temperature, DLTS measurements were performed on the nanowires grown on a non-treated Au/Si surface and on a thermally pre-treated Au/Si surface. A noticeable modification of the configuration of the energy levels was observed, induced by the annealing process. Based on our results on these MaWCE nanowires and on literature data about deep levels in bulk silicon, some hypotheses were advanced regarding the identification of the defects responsible of the energy levels revealed.

RESUMO

The traditional perception of ribosomes as uniform molecular machines has been revolutionized by recent discoveries, revealing a complex landscape of ribosomal heterogeneity. Opposing the conventional belief in interchangeable ribosomal entities, emerging studies underscore the existence of specialized ribosomes, each possessing unique compositions and functions. Factors such as cellular and tissue specificity, developmental and physiological states, and external stimuli, including circadian rhythms, significantly influence ribosome compositions. For instance, muscle cells and neurons are characterized by distinct ribosomal protein sets and dynamic behaviors, respectively. Furthermore, alternative forms of ribosomal RNA (rRNAs) and their post-transcriptional modifications add another dimension to this heterogeneity. These variations, orchestrated by spatial, temporal, and conditional factors, enable the manifestation of a broad spectrum of specialized ribosomes, each tailored for potentially distinct functions. Such specialization not only impacts mRNA translation and gene expression but also holds significant implications for broader biological contexts, notably in the realm of cancer research. As the understanding of ribosomal diversity deepens, it also paves the way for exploring novel avenues in cellular function and offers a fresh perspective on the molecular intricacies of translation.

RESUMO

snoRNAs are a class of non-coding RNAs known to guide site specifically RNA modifications such as 2'-O-methylation and pseudouridylation. Recent results regarding snoRNA alterations in cancer has been made available and suggest their potential evaluation as diagnostic and prognostic biomarkers. A large part of these data, however, was not consistently confirmed and failed to provide mechanistic insights on the contribution of altered snoRNA expression to the neoplastic process. Here, we aim to critically review the available literature on snoRNA in cancer focusing on the studies elucidating the functional consequences of their deregulation. Beyond the canonical guide function in RNA processing and modification we also considered additional roles in which snoRNA, in various forms and through different modalities, are involved and that have been recently reported.

RESUMO

Background/Aim: Cutaneous squamous cell carcinoma (SCC) is a common skin cancer with significant morbidity and mortality, particularly in advanced stages. Treatment options for metastatic cutaneous SCC in very elderly patients are limited due to concerns about treatment tolerability and potential adverse effects. Case Report: We report the case of a 90-year-old female patient with metastatic cutaneous SCC who was treated with cemiplimab, a monoclonal antibody (m-Ab) against programmed cell death protein 1 (PD-1), in combination with radiotherapy. The patient received cemiplimab for a limited period, during which time she demonstrated significant clinical improvement without severe adverse events. Radiotherapy was performed as a locoregional treatment with the aim to enhance immunotherapy efficacy. Discussion: This case highlights the feasibility and effectiveness of cemiplimab in very elderly patients with metastatic cutaneous SCC. Despite the common apprehensions regarding the use of immunotherapy in this age group, our patient tolerated cemiplimab well, and the combination with radiotherapy proved beneficial. This suggests that even in very elderly patients, short-term use of cemiplimab, in conjunction with locoregional treatments such as radiotherapy, can be a viable and successful therapeutic approach. Conclusion: Cemiplimab, even in combination with radiotherapy, can be effectively and safely administered to very elderly patients with metastatic cutaneous SCC. This case supports the consideration of immunotherapy, even for a limited duration, as a practical option in the management of advanced cutaneous SCC in elderly patients, expanding the potential treatment strategies for this population.

RESUMO

INTRODUCTION: The administration of proton pump inhibitors (PPIs) is a common practice to reduce gastro-esophageal adverse events associated with drug treatments but may impair absorption and exposure to oncology drugs. This study investigated the effect of concomitant administration of PPIs and pazopanib, sunitinib and cabozantinib on survival of patients with metastatic clear cell renal carcinoma (mRCC). PATIENTS AND METHODS: Total 451 patients receiving pazopanib, sunitinib and cabozantinib as first line treatment were enrolled in this retrospective study. Patients were defined as "no concomitant PPIs (PPI-)" if no PPIs were administered during TKIs, and as "concomitant PPIs (PPI+)" if the administration of PPIs was at least 75% of the time during which TKIs were given. RESULTS: Eighty patients administered pazopanib were PPI- and 86 PPI+; no difference in PFS was observed (10.7 vs. 11.9 months, P = .79). If patients were stratified as short (n = 89) and long (n = 77) responders, there was a significant difference in terms of PFS in PPI+ (n = 47) versus PPI- (n = 30) in long responders, being 24.7 versus 38 months (P = .04), respectively. In the sunitinib cohort, no significant difference of PFS in PPI+ (n = 102) versus PPI- (n = 131) was found, being 11.3 versus 18.1 months, respectively (P=0.15). In the cabozantinib cohort, there was a statistically significant difference in PFS of PPI+ versus PPI- (6 months vs. not reached, P = .04). No correlation with adverse events was found. CONCLUSIONS: This study demonstrates an association between PPIs and impaired PFS in mRCC patients given pazopanib and cabozantinib and recommends caution on their concomitant use.

RESUMO

BACKGROUND & AIMS: Cirrhosis and its complications may affect gut microbiota (GM) composition. Transjugular intrahepatic portosystemic shunt (TIPS) represents the most effective treatment for portal hypertension (PH). We aimed to evaluate whether TIPS placement modifies GM composition and metabolic function. METHODS: A compositional and functional GM analysis was prospectively performed in 13 cirrhotic patients receiving TIPS. Patients receiving systemic or non-absorbable antibiotics for any indications were excluded. Fecal samples were collected before and three months after TIPS. GM was analyzed by 16S ribosomal RNA sequencing. Small- and medium-chain fatty acids (SCFAs and MCFAs, respectively) were measured by gas chromatography/mass spectrometry. RESULTS: TIPS placement resulted in a mean 48% reduction in portal-caval pressure gradient. No recurrence of PH related complications was observed. After TIPS, increased levels of Flavonifractor spp. (p = 0.049), and decreased levels of Clostridiaceae (p = 0.024), these latter linked to abdominal infections in cirrhotic patients, were observed. No differences were found in the SCFAs signature while analysis of MCFA profiles showed a decreased abundance of pro-inflammatory isohexanoic (p<0.01), 2-ethylhexanoic (p<0.01) and octanoic acids (p<0.01) after TIPS. CONCLUSION: Correction of PH following TIPS results in modifications of GM composition which could be potentially beneficial and reduces the levels of fecal pro-inflammatory MCFAs.

RESUMO

In this paper, we present an overview of existing parallel corpora for Automatic Text Simplification (ATS) in different languages focusing on the approach adopted for their construction. We make the main distinction between manual and (semi)-automatic approaches in order to investigate in which respect complex and simple texts vary and whether and how the observed modifications may depend on the underlying approach. To this end, we perform a two-level comparison on Italian corpora, since this is the only language, with the exception of English, for which there are large parallel resources derived through the two approaches considered. The first level of comparison accounts for the main types of sentence transformations occurring in the simplification process, the second one examines the results of a linguistic profiling analysis based on Natural Language Processing techniques and carried out on the original and the simple version of the same texts. For both levels of analysis, we chose to focus our discussion mostly on sentence transformations and linguistic characteristics that pertain to the morpho-syntactic and syntactic structure of the sentence.

RESUMO

BACKGROUND: In Italy, abortion services are public: therefore, health Institutions should provide clear and easily readable web-based information. We aimed to 1) assess variation in abortion services utilisation; 2) analyse the readability of institutional websites informing on induced abortion; 3) explore whether easier-to-read institutional websites influenced the correct fruition of abortion services. METHODS: We identified from the 2021 administrative databases of Tuscany all women having an abortion, and-among them-women having an abortion with the certification provided by family counselling centres, following the pathway established by law. We assessed variation in total and certified abortion rates by computing the Systematic Component of Variation. We analysed the readability of the Tuscan health authorities' websites using the readability assessment tool READ-IT. We explored how institutional website readability influenced the odds of having certified abortions by running multilevel logistic models, considering health authorities as the highest-level variables. RESULTS: We observed high variation in the correct utilization of the abortion pathway in terms of certified abortion rates. The READ-IT scores showed that the most readable text was from the Florence Teaching Hospital website. Multilevel models revealed that higher READ-IT scores, corresponding to more difficult texts, resulted in lower odds of certified abortions. CONCLUSIONS: Large variation in the proper fruition of abortion pathways occurs in Tuscany, and such variation may depend on readability of institutional websites informing on induced abortion. Therefore, health Institutions should monitor and improve the readability of their websites to ensure proper and more equitable access to abortion.
