Nurses prioritization processes to prevent delirium in patients at risk: Findings from a Q-Methodology study.

BACKGROUND: This study aimed at (a) exploring how nurses prioritise interventions to prevent delirium among patients identified at risk and (b) describing the underlying prioritisation patterns according to nurses' individual characteristics. METHODS: There was used the Q-methodology a research process following specific steps: (a) identifying the concourse, (b) the Q-sample, and (c) the population (P-set); (d) collecting data using the Q-sort table; (e) entering the data and performing the factor analysis; and (f) interpreting the factors identified. RESULTS: There were involved 56 nurses working in medical, geriatric and log-term facilities (46; 82.2 %). The preventive intervention receiving the highest priority was 'Monitoring the vital parameters (heart rate, blood pressure, oxygen saturation)' (2.96 out of 4 as the highest priority; CI 95 %: 2.57, 3.36). Two priority patterns emerged among nurses (explained variance 44.78 %), one 'Clinical-oriented' (36.19 %) and one 'Family/caregiver-oriented' (8.60 %) representing 53 nurses out 56. CONCLUSION: Alongside the overall tendency to prioritise some preventive interventions instead of others, the priorities are polarised in two main patterns expressing two main individual characteristics of nurses. Knowing the existence of individual patterns and their aggregation informs how to shape educational interventions.

Capsular Warning Syndrome: Features, Risk Profile, and Prognosis in a Large Prospective TIA Cohort.

INTRODUCTION: Features and prognosis of capsular warning syndrome (CWS) have been poorly investigated prospectively. AIMS: The study aimed to characterize CWS clinical features, risk profile, short- and long-term prognosis, among a large TIA cohort. METHODS: Prospective cohort study of consecutive TIAs was conducted from August 1, 2010, to December 31, 2017. Demographic and clinical characteristics, risk profile, primary (stroke and composite outcome) and secondary (TIA recurrence, cerebral hemorrhage, new onset atrial fibrillation) outcomes were compared between CWS, lacunar (L), and nonlacunar (NL) TIAs. RESULTS: 1,035 patients (33 CWS, 189 L-TIAs, 813 NL-TIAs) were enrolled. Newly diagnosed (ND) hypertension, hypercholesterolemia, cigarette smoking, and leukoaraiosis were independent risk factors of CWS (p < 0.05). CWS showed the highest stroke (30.3% vs. 0.5% and 1.5% for L-TIAs and NL-TIAs, respectively) and composite outcome risk at follow-up (p < 0.001), but better 3-month post-stroke prognosis (mRS 0-2 90.0% vs. 36.8%; p = 0.002). CWS-related stroke mostly occurred <48 h (80.0%) and had a small vessel occlusion etiology (100%), affecting more often the internal capsule (60.0%). Dual antiplatelet therapy (DAPT) versus single antiplatelet therapy was associated with lower 3-month cumulative stroke incidence (12.5% vs. 57.1%; p = 0.010). Intravenous thrombolysis (IVT) showed similar 3-month efficacy and safety in strokes after TIAs groups (median mRS 0, IQR 0-1; p = 0.323). CONCLUSIONS: CWS is associated with higher stroke risk and better functional prognosis than L- and NL-TIAs. CWS risk profile is consistent with severe small vessel disease, and ND hypertension could represent a major risk factor. DAPT and IVT seem effective and safe in preventing and treating stroke following CWS.

High-Flow Nasal Oxygen for Severe Hypoxemia: Oxygenation Response and Outcome in Patients with COVID-19.

Rationale: The "Berlin definition" of acute respiratory distress syndrome (ARDS) does not allow inclusion of patients receiving high-flow nasal oxygen (HFNO). However, several articles have proposed that criteria for defining ARDS should be broadened to allow inclusion of patients receiving HFNO. Objectives: To compare the proportion of patients fulfilling ARDS criteria during HFNO and soon after intubation, and 28-day mortality between patients treated exclusively with HFNO and patients transitioned from HFNO to invasive mechanical ventilation (IMV). Methods: From previously published studies, we analyzed patients with coronavirus disease (COVID-19) who had PaO2/FiO2 of ⩽300 while treated with ⩾40 L/min HFNO, or noninvasive ventilation (NIV) with positive end-expiratory pressure of ⩾5 cm H2O (comparator). In patients transitioned from HFNO/NIV to invasive mechanical ventilation (IMV), we compared ARDS severity during HFNO/NIV and soon after IMV. We compared 28-day mortality in patients treated exclusively with HFNO/NIV versus patients transitioned to IMV. Measurements and Main Results: We analyzed 184 and 131 patients receiving HFNO or NIV, respectively. A total of 112 HFNO and 69 NIV patients transitioned to IMV. Of those, 104 (92.9%) patients on HFNO and 66 (95.7%) on NIV continued to have PaO2/FiO2 ⩽300 under IMV. Twenty-eight-day mortality in patients who remained on HFNO was 4.2% (3/72), whereas in patients transitioned from HFNO to IMV, it was 28.6% (32/112) (P < 0.001). Twenty-eight-day mortality in patients who remained on NIV was 1.6% (1/62), whereas in patients who transitioned from NIV to IMV, it was 44.9% (31/69) (P < 0.001). Overall mortality was 19.0% (35/184) and 24.4% (32/131) for HFNO and NIV, respectively (P = 0.2479). Conclusions: Broadening the ARDS definition to include patients on HFNO with PaO2/FiO2 ⩽300 may identify patients at earlier stages of disease but with lower mortality.

Identifying patient subgroups with different trends of patient-reported outcomes (PROMs) after elective knee arthroplasty.

BACKGROUND: Patient-reported outcome measures (PROMs) are increasingly being used to assess the effectiveness of elective total knee arthroplasty (TKA). However, little is known about how PROMs scores change over time in these patients. The aim of this study was to identify the trajectories of quality of life and joint functioning, and their associated demographic and clinical features in patients undergoing elective TKA. METHODS: A prospective, cohort study was conducted, in which PROMs questionnaires (Euro Quality 5 Dimensions 3L, EQ-5D-3L, and Knee injury and Osteoarthritis Outcome Score Patient Satisfaction, KOOS-PS) were administered to patients at a single center undergoing elective TKA before surgery, and at 6 and 12 months after surgery. Latent class growth mixture models were used to analyze the patterns of change in PROMs scores over time. Multinomial logistic regression was used to investigate the association between patient characteristics and PROMs trajectories. RESULTS: A total of 564 patients were included in the study. The analysis highlighted differential patterns of improvement after TKA. Three distinct PROMs trajectories were identified for each PROMs questionnaire, with one trajectory indicating the most favorable outcome. Female gender appears to be associated with a presentation to surgery with worse perceived quality of life and joint function than males, but also more rapid improvement after surgery. Having an ASA score greater than 3 is instead associated with a worse functional recovery after TKA. CONCLUSION: The results suggest three main PROMs trajectories in patients undergoing elective TKA. Most patients reported improved quality of life and joint functioning at 6 months, which then stabilized. However, other subgroups showed more varied trajectories. Further research is needed to confirm these findings and to explore the potential clinical implications of these results.

Applicability of the interventions recommended for patients at risk or with delirium in medical and post-acute settings: a systematic review and a Nominal Group Technique study.

BACKGROUND: Delirium is a common condition during hospitalisation that should be prevented and treated. Several recommendations have been established to date, whereas few studies have investigated their applicability in daily practice for medical and post-acute settings. AIM: The aim of this research exercise was to emerge the applicability of the interventions recommended by studies in the daily care of patients at risk or with delirium cared in medical and post-acute settings. METHODS: The study was organised in three phases. A systematic literature review according to Centre for Reviews and Dissemination was conducted (January-February 2021). Cochrane Library, Pubmed, Scopus, Cumulative Index to Nursing and Allied Health Literature, Psychological Information Database, and the Joanna Briggs Institute databases were searched. Primary and secondary studies were evaluated in their methodological quality with the Standard Quality Assessment Criteria, the Critical Appraisal Skills Programme, and the Appraisal of Guidelines for Research & Evaluation. Then, the interventions identified were assessed in their applicability using the Nominal Group Technique who ranked their judgement on a four-point Likert scale from 1 (totally inapplicable) to 4 (totally applicable). Qualitative feedbacks were also considered, and a validation of the final list was performed by the Nominal Group. RESULTS: A total of 12 studies were included producing a list of 96 interventions categorised into four macro-areas (prevention, non-pharmacological, communication and pharmacological management). The Nominal Group identified 51 interventions (average score > 3.5) as applicable in medical and post-acute settings. Then, through a process of re-reading, and revising according to the comments provided by the Nominal Group, a list of 35 interventions out of the initial 96 were judged as applicable. CONCLUSION: Applicability should be assessed with experts in the field to understand the involved factors. One-third of interventions have been judged as applicable in the Italian context; the nurses' expertise, the work environment features, and the time required for each intervention in a high workload setting may prevent the full applicability of the interventions recommended by the literature.

Hyperglycemia, inflammatory response and infarct size in obstructive acute myocardial infarction and MINOCA.

BACKGROUND: Hyperglycemia has been associated with increased inflammatory indexes and larger infarct sizes in patients with obstructive acute myocardial infarction (obs-AMI). In contrast, no studies have explored these correlations in non-obstructive acute myocardial infarction (MINOCA). We investigated the relationship between hyperglycemia, inflammation and infarct size in a cohort of AMI patients that included MINOCA. METHODS: Patients with AMI undergoing coronary angiography between 2016 and 2020 were enrolled. The following inflammatory markers were evaluated: C-reactive protein, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and neutrophil-to-platelet ratio (NPR). Myocardial infarct size was measured by peak high sensitivity troponin I (Hs-TnI) levels, left-ventricular-end-diastolic-volume (LVEDV) and left ventricular ejection fraction (LVEF). RESULTS: The final study population consisted of 2450 patients with obs-AMI and 239 with MINOCA. Hyperglycemia was more prevalent among obs-AMI cases. In all hyperglycemic patients-obs-AMI and MINOCA-NLR, NPR, and LPR were markedly altered. Hyperglycemic obs-AMI subjects exhibited a higher Hs-TnI (p < 0.001), a larger LVEDV (p = 0.003) and a lower LVEF (p < 0.001) compared to normoglycemic ones. Conversely, MINOCA patients showed a trivial myocardial damage, irrespective of admission glucose levels. CONCLUSIONS: Our data confirm the association of hyperglycemic obs-AMI with elevated inflammatory markers and larger infarct sizes. MINOCA patients exhibited modest myocardial damage, regardless of admission glucose levels.

Impact of admission hyperglycemia on short and long-term prognosis in acute myocardial infarction: MINOCA versus MIOCA.

BACKGROUND: The prognostic role of hyperglycemia in patients with myocardial infarction and obstructive coronary arteries (MIOCA) is acknowledged, while data on non-obstructive coronary arteries (MINOCA) are still lacking. Recently, we demonstrated that admission stress-hyperglycemia (aHGL) was associated with a larger infarct size and inflammatory response in MIOCA, while no differences were observed in MINOCA. We aim to investigate the impact of aHGL on short and long-term outcomes in MIOCA and MINOCA patients. METHODS: Multicenter, population-based, cohort study of the prospective registry, designed to evaluate the prognostic information of patients admitted with acute myocardial infarction to S. Orsola-Malpighi and Maggiore Hospitals of Bologna metropolitan area. Among 2704 patients enrolled from 2016 to 2020, 2431 patients were classified according to the presence of aHGL (defined as admission glucose level ≥ 140 mg/dL) and AMI phenotype (MIOCA/MINOCA): no-aHGL (n = 1321), aHGL (n = 877) in MIOCA and no-aHGL (n = 195), aHGL (n = 38) in MINOCA. Short-term outcomes included in-hospital death and arrhythmias. Long-term outcomes were all-cause and cardiovascular mortality. RESULTS: aHGL was associated with a higher in-hospital arrhythmic burden in MINOCA and MIOCA, with increased in-hospital mortality only in MIOCA. After adjusting for age, gender, hypertension, Killip class and AMI phenotypes, aHGL predicted higher in-hospital mortality in non-diabetic (HR = 4.2; 95% CI 1.9-9.5, p = 0.001) and diabetic patients (HR = 3.5, 95% CI 1.5-8.2, p = 0.003). During long-term follow-up, aHGL was associated with 2-fold increased mortality in MIOCA and a 4-fold increase in MINOCA (p = 0.032 and p = 0.016). Kaplan Meier 3-year survival of non-hyperglycemic patients was greater than in aHGL patients for both groups. No differences in survival were found between hyperglycemic MIOCA and MINOCA patients. After adjusting for age, gender, hypertension, smoking, LVEF, STEMI/NSTEMI and AMI phenotypes (MIOCA/MINOCA), aHGL predicted higher long-term mortality. CONCLUSIONS: aHGL was identified as a strong predictor of adverse short- and long-term outcomes in both MIOCA and MINOCA, regardless of diabetes. aHGL should be considered a high-risk prognostic marker in all AMI patients, independently of the underlying coronary anatomy. Trial registration data were part of the ongoing observational study AMIPE: Acute Myocardial Infarction, Prognostic and Therapeutic Evaluation. ClinicalTrials.gov Identifier: NCT03883711.

HCV cirrhotic patients treated with direct-acting antivirals: Detection of tubular dysfunction and resolution after viral clearance.

BACKGROUND/AIMS: Hepatitis C virus (HCV) has been identified in tubular epithelial cells of infected patients; however, the presence of tubular dysfunction, which is a risk factor for chronic kidney disease (CKD), has never been examined in vivo. The present prospective longitudinal study aimed to estimate the prevalence of tubular dysfunction alone or with glomerular damage and its evolution after HCV clearance in cirrhotic patients. METHODS: One hundred and thirty-five consecutive Child-Pugh A cirrhotic patients were evaluated before antiviral treatment and 6 months after the end of therapy. Tubular dysfunction was evaluated by urinary alpha1-microglobulin to creatinine ratio (α1-MCR), and glomerular damage was assessed by urinary albumin to creatinine ratio (ACR). RESULTS: Almost all the patients (93.3%) showed a normal or mildly decreased e-GFR (KDIGO-G1/G2-categories). Tubular dysfunction was found in 23.7% (32/135) of patients, co-occurring with glomerular damage in 37.5% (12/32) of cases, while glomerular damage was found in 16.3% (22/135) of patients. In multiple logistic regression, glomerular damage and the concomitant presence of diabetes and hypertension were the only predictors significantly associated with tubular dysfunction. After HCV clearance, patients experienced a significant reduction of α1-MCR levels (21.0 vs 10.5 µg/mg, P = .009) and tubular dysfunction resolved in 57.1% of subjects. CONCLUSIONS: Tubular dysfunction is an unrecognized feature of HCV-related kidney disease in cirrhotic patients and its presence should be primarily investigated in subjects with glomerular damage, diabetes and hypertension, despite normal e-GFR. Tubular dysfunction resolves in the majority of cases after HCV clearance; however, it may persist after antiviral treatment and further studies should evaluate its long-term impact on kidney function.

The changing scenario of hepatocellular carcinoma in Italy: an update.

BACKGROUND AND AIMS: Epidemiology of hepatocellular carcinoma (HCC) is changing in most areas of the world. This study aimed at updating the changing scenario of aetiology, clinical presentation, management and prognosis of HCC in Italy during the last 15 years. METHODS: Retrospective analysis of the Italian Liver Cancer (ITA.LI.CA) database included 6034 HCC patients managed in 23 centres from 2004 to 2018. Patients were divided into three groups according to the date of cancer diagnosis (2004-2008, 2009-2013 and 2014-2018). RESULTS: The main results were: (i) a progressive patient ageing; (ii) a progressive increase of non-viral cases and, particularly, of 'metabolic' and 'metabolic + alcohol' HCCs; (iii) a slightly decline of cases diagnosed under surveillance, but with an incremental use of the semiannual schedule; (iv) a favourable cancer stage migration; (v) an increased use of radiofrequency ablation to the detriment of percutaneous ethanol injection; (vi) improved outcomes of ablative and transarterial treatments; (vii) an improved overall survival (adjusted for the lead time in surveyed patients) in the last calendar period, particularly in viral patients; (viii) a large gap between the number of potential candidates (according to oncologic criteria and age) to liver transplant and that of transplanted patients. CONCLUSIONS: During the last 15 years several aspects of HCC scenario have changed, as well as its management. The improvement in patient survival observed in the last period was likely because of a larger use of thermal ablation with respect to the less effective alcohol injection and to an improved management of intermediate stage patients.

Suicidality in patients with obsessive-compulsive and related disorders (OCRDs): A meta-analysis.

INTRODUCTION: Previous meta-analyses showed that OCD is associated with a substantial risk of suicidal behaviours. Conclusive rates of suicidal ideation (current and lifetime) and suicide attempts based on pooled prevalence rates have not so far been calculated using meta-analysis for the other DSM-5 Obsessive-Compulsive and Related Disorders (OCRDs). OBJECTIVES: This meta-analysis aims to separately calculate the pooled prevalence rates of lifetime suicide attempts and current or lifetime suicidal ideation in BDD, Hoarding Disorder (HD), Skin Picking Disorder (SPD) and Trichotillomania (TTM) and to identify factors associated with increased suicide rates. METHODS: Our protocol was pre-registered with PROSPERO (CRD42020164395). A systematic review and meta-analysis following PRISMA reporting guidelines was performed by searching in PubMed/Medline, PsycINFO, Web of Science and CINAHL databases from the date of the first available article to April 20th, 2020. Stata version 15 was used for the statistical analysis. Given the small number of studies in TTM and SPD, the two grooming disorders were grouped together. Meta-analyses of proportions based on random effects (Der-Simonian and Laird method) were used to derive the pooled estimates. RESULTS: Thirty-eigth studies (N = 4559 participants) were included: 23 for BDD, 8 for HD, 7 for Grooming Disorders. For BDD, the pooled prevalence of lifetime suicide attempts, current and lifetime suicidal ideation was, respectively 35.2% (CI:23.4-47.8), 37.2% (CI:23.8-51.6) and 66.1% (CI:53.5-77.7). For HD, the pooled prevalence of lifetime suicide attempts, current and lifetime suicidal ideation was 24.1% (CI:12.8-37.6), 18.4% (CI:10.2-28.3) and 38.3% (CI:35.0-41.6), respectively. For Grooming Disorders, the pooled prevalence of lifetime suicide attempts and current suicidal ideation were 13.3% (CI:5.9-22.8) and 40.4% (CI:35.7-45.3), respectively (no data available for lifetime suicidal ideation). CONCLUSIONS: The OCRDs as a group are associated with relatively high rates of suicidal behaviour. Through indirect comparisons, we infer that BDD has the greatest risk. Comorbid substance abuse, possibly reflecting poor underlying impulse control, is associated with higher rates of suicidal behaviour in BDD. Our data emphasize the need for clinicians to consider the risk of suicidal behaviour in the management of patients presenting with all forms of OCRDs.

Comorbid diseases associated with pemphigus: a case-control study.

BACKGROUND AND OBJECTIVES: Pemphigus has been associated with physical and psychiatric comorbid diseases. This study aims to further investigate these associations in patients with pemphigus, and to analyze the relationships of comorbid conditions with sex and age, pemphigus disease area index score, diagnostic delay and cutaneous/mucous involvement. PATIENTS AND METHODS: Patients with pemphigus were matched by age, gender and area of residence with eight controls each. The odds of comorbid conditions in patients vs. matched controls was determined using univariate conditional logistic regression models. Comorbid diseases significantly associated with the diagnosis of pemphigus at P < 0.05 in univariate models were subsequently included in a multivariable conditional logistic regression model with a forward procedure. RESULTS: The study sample included 163 patients with pemphigus. Cardiovascular diseases, hyperlipidemia, autoimmune thyroid disorders, dermatological autoimmune/inflammatory conditions and cancer were the most prominent conditions at the time of diagnosis. In the multiple conditional regression analysis, the two diagnoses independently associated with patients with pemphigus were cancer and dermatological autoimmune/inflammatory conditions. In sensitivity analyses excluding four patients with paraneoplastic pemphigus, these associations were still significant. CONCLUSIONS: Cancer and dermatological autoimmune/inflammatory conditions may represent possible triggering conditions for pemphigus and should be considered as early warning signs for the disease.

Komorbidität bei Pemphigus: eine Fall-Kontroll-Studie.

HINTERGRUND UND ZIELE: Pemphigus ist mit physischen und psychischen Erkrankungen assoziiert. Diese Studie soll derartige Zusammenhänge bei Patienten mit Pemphigus näher untersuchen sowie die Komorbidität nach Geschlecht, Alter, dem Pemphigus Disease Area Index, der Diagnoseverzögerung und der Beteiligung von Haut/Schleimhaut analysieren. PATIENTEN UND METHODEN: Jedem Pemphigus-Patienten wurden acht Kontrollen mit ähnlichem Alter, Geschlecht und Wohnsitz zugeordnet. Die Wahrscheinlichkeit für Begleiterkrankungen bei Patienten und Kontrollpersonen wurde anhand univariater konditionaler Regressionsmodelle bestimmt. Begleiterkrankungen, die in den univariaten Modellen mit P < 0,05 mit der Diagnose Pemphigus assoziiert waren, wurden dann in einem Vorwärtsverfahren in ein multivariates konditionales Regressionsmodell eingefügt. ERGEBNISSE: Die Studie umfasste 163 Patienten mit Pemphigus. Die hauptsächlichen Erkrankungen zum Diagnosezeitpunkt waren kardiovaskuläre Erkrankungen, Hyperlipidämie, Autoimmunerkrankungen der Schilddrüse, autoimmune/entzündliche Dermatosen und Krebs. In der multivariaten konditionalen Regressionsanalyse waren Krebs und autoimmune/entzündliche Dermatosen unabhängig mit Pemphigus assoziiert. In Sensitivitätsanalysen, in denen vier Patienten mit paraneoplastischem Pemphigus ausgeschlossen wurden, waren diese Assoziationen ebenfalls signifikant. SCHLUSSFOLGERUNGEN: Krebs und autoimmune/entzündliche Dermatosen sind möglicherweise auslösende Faktoren für Pemphigus dar und sollten als frühe Warnsignale für diese Erkrankung angesehen werden.

Cardiovascular and cerebrovascular responses to cardio-respiratory events in preterm infants during the transitional period.

KEY POINTS: Non-invasive simultaneous multiparametric monitoring allows the in vivo evaluation of cerebral and cardiovascular haemodynamic responses to different types of recurrent episodes of intermittent hypoxia and/or bradycardia, also defined as cardio-respiratory events (CRE), in preterm neonates during postnatal transition. By decreasing left cardiac output, bradycardia further contributes to cerebral hypoxia during CRE. The presence of a haemodynamically significant patent ductus arteriosus results in a deeper impairment of cerebral oxygen status in response to CRE, whereas the brain-sparing remodelling of the fetal circulation resulting from placental insufficiency is associated with more favourable haemodynamic responses to intermittent hypoxia. During transition, the haemodynamic impact of CRE is influenced not only by the event type, but also by specific clinical features; this highlights the importance of developing individualized approaches to reduce the hypoxic burden in this delicate phase. ABSTRACT: The present observational prospective study aimed to investigate cerebral and cardiovascular haemodynamic responses to different types of cardio-respiratory events (CRE) in preterm infants during postnatal transition, as well as evaluate the impact of relevant clinical characteristics. Infants with gestational age (GA) <32 weeks and/or birth weight <1500 g were enrolled after birth. Cerebral oxygenation index (cTOI), fractional oxygen extraction (cFTOE), cardiac output (CO), cardiac contractility (iCON) and systemic vascular resistances (sVR) were simultaneously monitored over the first 72 h by near-infrared spectroscopy and electrical velocimetry. CRE were clustered into isolated bradycardia (IB), isolated desaturation (ID) and combined desaturation/bradycardia (DB). For each parameter, percentage changes from baseline (%Δ) were calculated. The impact of different CRE types and clinical variables on %Δ was evaluated with generalized estimating equations. In total, 1426 events were analysed. %ΔcTOI significantly differed among ID, IB and DB (P < 0.001), with the latter showing the greatest drop. %ΔcFTOE decreased significantly during DB (P < 0.001) and ID (P < 0.001) compared to IB. DB and IB were associated with more negative %ΔCO (P < 0.001) and more positive %ΔsVR (P < 0.001) compared to ID. A slight iCON reduction was observed during DB compared to ID (P = 0.043). Antenatal umbilical Doppler impairment, GA and the presence of a haemodynamically significant patent ductus arteriosus had a significant independent impact on %ΔcTOI, %ΔcFTOE and %ΔCO. During the transitional period, the haemodynamic responses to CRE are influenced by the event type and by specific neonatal characteristics, suggesting the importance of targeted individualized approaches for minimizing the risk of cerebral injury in the preterm population.

Cardiorespiratory Events in Infants Born Preterm during the Transitional Period.

OBJECTIVE: To investigate the features of cardiorespiratory events in infants born preterm during the transitional period, and to evaluate whether different neonatal characteristics may correlate with event type, duration, and severity. STUDY DESIGN: Infants with gestational age (GA) <32 weeks and/or birth weight <1500 g were enrolled in this observational prospective study. Heart rate (HR) and peripheral oxygen saturation (SpO2) were recorded continuously over the first 72 hours. Cardiorespiratory events of ≥10 seconds were clustered into isolated desaturation (SpO2 <85%), isolated bradycardia (HR <100 bpm or <70% of baseline), or combined desaturation/bradycardia and classified as mild, moderate, or severe. The daily incidences of isolated desaturation, isolated bradycardia, and combined desaturation and bradycardia were analyzed. The effects of relevant clinical variables on cardiorespiratory event type and severity were assessed using generalized estimating equations. RESULTS: Among the 1050 events analyzed, isolated desaturations were the most frequent (n = 625) and isolated bradycardias the least common (n = 171). The number of cardiorespiratory events increased significantly from day 1 to day 2 (P = .028). One in 5 events had severe characteristics; event severity was highest for combined desaturation and bradycardia (P < .001). Compared with other event types, the incidence of combined desaturation and bradycardia was inversely correlated with GA (P = .029) and was higher with the use of continuous positive airway pressure (P = .002). The presence of a hemodynamically significant patent ductus arteriosus was associated with the occurrence of isolated desaturations (P = .001) and with a longer duration of cardiorespiratory events (P = .003). CONCLUSIONS: Cardiorespiratory events during transition exhibit distinct types, duration, and severity. Neonatal characteristics are associated with the clinical features of these events, indicating that a tailored clinical approach may reduce the hypoxic burden in preterm infants aged 0-72 hours.

Post-radiotherapy vascular lesions of the breast: immunohistochemical and molecular features of 74 cases with long-term follow-up and literature review.

AIMS: A wide range of post-radiotherapy (RT) vascular lesions can occur, ranging from benign lymphangiomatous papules of the skin (BLAPs), to atypical vascular lesions (AVLs) and post-RT angiosarcomas (ASs). The relationship between benign and malignant post-RT breast lesions and their prognostic features are still controversial. The aims of this study were to investigate the relationship between benign and malignant mammary post-RT vascular lesions and to define post-RT AS prognostic features. METHODS AND RESULTS: Seventy-four post-RT vascular lesion cases were obtained and stained with antibodies against CD34, CD31, D2-40, Ki67, and c-Myc. Mutational analysis was performed by deep sequencing for the following genes: KRAS, NRAS, HRAS, BRAF, PIK3CA, TP53, NOTCH1, PTEN, CDKN2A, EGFR, AKT1, CTNNB1, hTERT, and PTPRB. Post-RT AS cases were graded according to a previously reported breast AS grading system. AVL cases showed a low number of HRAS and hTERT mutations, whereas post-RT AS cases showed a high frequency of EGFR, TP53, HRAS and hTERT mutations. On follow-up, all BLAP and AVL patients were alive with no evidence of disease. Post-RT AS 5-year overall survival declined with the increase in grade, as follows: 85.7% for grade 1, 83.3% for grade 2, and 40.4% for grade 3. CONCLUSIONS: Our findings confirm that BLAP and AVL have a good prognosis, and that post-RT AS prognosis is strongly related to histological grading. On molecular analysis, AVL and post-RT AS shared HRAS and hTERT mutations, suggesting a relationship between the two lesions.

Red blood cell transfusions alter splanchnic oxygenation response to enteral feeding in preterm infants: an observational pilot study.

BACKGROUND: Preterm infants often require red blood cell (RBC) transfusions, which may impair splanchnic hemodynamics, thus predisposing to necrotizing enterocolitis (NEC). The aim of this study was to evaluate whether RBC transfusions alter splanchnic oxygenation patterns in response to enteral feeding in this population. MATERIALS AND METHODS: Preterm neonates (gestational age < 32 weeks and/or birth weight < 1500 g) requiring RBC transfusions for anemia underwent a 12-hour Near Infrared Spectroscopy monitoring of splanchnic (SrSO2 ) and cerebral (CrSO2 ) oxygenation, including the transfusion period, one feed before and one after. Splanchnic-cerebral oxygenation ratio (SCOR) was also calculated. Patterns of CrSO2 , SrSO2 , and SCOR changes from baseline (Δ) in response to feed before and after transfusion were analyzed. RESULTS: Twenty neonates were enrolled; none of them developed any gastrointestinal complication within 48 hours after transfusion. Pre-transfusion ΔSrSO2 and ΔSCOR increased significantly in response to feeding; on the contrary, a significant post-prandial decrease of ΔSrSO2 and ΔSCOR occurred after transfusion (p < 0.05). No difference in pre- and post-transfusion ΔCrSO2 patterns was observed. CONCLUSIONS: In preterm infants, RBC transfusions may alter splanchnic oxygenation response to enteral feeds. Whether these changes are involved in the pathogenesis of transfusion-associated NEC has to be evaluated in further larger trials.

Mood spectrum symptoms during a major depressive episode: Differences between 145 patients with bipolar disorder and 155 patients with major depressive disorder. Arguments for a dimensional approach.

BACKGROUND: Several studies have challenged the traditional unipolar-bipolar dichotomy in favor of a more dimensional approach. OBJECTIVE: To evaluate the differences in mood spectrum between patients with bipolar disorder (BD) and major depressive disorder (MDD) during a major depressive episode (MDE). METHOD: Study participants were 145 patients with BD and 155 patients with MDD recruited at three University Medical Centers in Italy. All study subjects met Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria for MDE and completed the Mood Spectrum-Self-Report-Last Month questionnaire. RESULTS: Patients with BD endorsed more items in the mood manic/hypomanic and energy depressive subdomains of the MOODS-SR questionnaire. Significant differences were also found for specific depressive and manic items, which were more frequently endorsed by patients with BD. A large number of patients with BD, but also a considerable number of patients with MDD, endorsed manic items during a depressive episode. CONCLUSIONS: There are differences between BD and MDD in terms of the number and type of mood spectrum items that are endorsed during a MDE, which may help to identify patients with BD when a retrospective assessment of a history of mania or hypomania is not possible or not reliable. A high number of patients with BD and a considerable number of patients with MDD endorsed several items in the manic section of the mood, energy, and cognition domains, this confirming the centrality of mixed features in patients with mood disorders and the need for a unitary, dimensional, descriptive and dynamic approach to MDD and BD, such as the recently proposed ACE (Activity, Cognition, Energy) model.

Effectiveness of clinical decision support systems and telemedicine on outcomes of depression: a cluster randomized trial in general practice.

BACKGROUND: Computerized Clinical Decision Support Systems (CCDSS) are information technology tools, designed to improve clinical decision-making. Telemedicine is a health care service delivery using videoconferencing, telephone or messaging technologies. OBJECTIVES: Our project aimed at testing the effectiveness of a composite CCDSS and telemedicine approach designed to treat depression in primary care. METHODS: This cluster randomized trial involved four GP clinics located in Northern Italy. Two clinics were assigned to the experimental protocol, and two served as controls. The study compared the telemedicine group (TG), in which GPs had access to a CCDSS platform, with the control group (CG) in which GPs provided treatment as usual (TAU). Patients scoring ≥11 on Patient Heath Questionnaire and ≥26 on the Inventory of Depressive Symptomatology-Self-Report were eligible for participation. Patients were also administered the World Health Organization Quality of Life-BREF to assess quality of life and Medical Interview Satisfaction Scale 21 to assess satisfaction with the medical interview. RESULTS: Overall, 2810 patients were screened and 66 in the experimental group and 32 in the CG passed the screening stages and met inclusion criteria. The percentage of remitters at 6 months was significantly higher in the TG than in the CG group (24.1% versus 3.1%, χ 2 = 6.6, P = 0.01). This difference remained significant after adjusting for baseline confounders. Physical and psychological quality of life improved significantly from baseline in both groups. Patients reported, on average, good satisfaction with the medical interview. CONCLUSIONS: Our study showed that a combined CCDSS and telemedicine approach may be more effective than the TAU offered by GPs to patients with depression. TRIAL REGISTRATION: The trial was registered on https://clinicaltrials.gov/ on 5 October 2012 with identifier: NCT01701791. The first participant was enrolled on 5 May 2014 and the study was completed on May 2016.

Early CSF Biomarkers and Late Functional Outcomes in Spinal Cord Injury. A Pilot Study.

Although, biomarkers are regarded as an important tool for monitoring injury severity and treatment efficacy, and for predicting clinical evolution in many neurological diseases and disorders including spinal cord injury, there is still a lack of reliable biomarkers for the assessment of clinical course and patient outcome. In this study, a biological dataset of 60 cytokines/chemokines, growth factorsm and intracellular and extracellular matrix proteins, analyzed in CSF within 24 h of injury, was used for correlation analysis with the clinical dataset of the same patients. A heat map was generated of positive and negative correlations between biomarkers and clinical rating scale scores at discharge, and between biomarkers and changes in clinical scores during the observation period. Using very stringent statistical criteria, we found 10 molecules which correlated with clinical scores at discharge, and five molecules, which correlated with changes in clinical scores. The proposed methodology may be useful for generating hypotheses regarding "predictive" and "treatment effectiveness" biomarkers, thereby suggesting potential candidates for disease-modifying therapies using a "bed-to-bench" approach.

Temporal validation of the CT-PIRP prognostic model for mortality and renal replacement therapy initiation in chronic kidney disease patients.

BACKGROUND: A classification tree model (CT-PIRP) was developed in 2013 to predict the annual renal function decline of patients with chronic kidney disease (CKD) participating in the PIRP (Progetto Insufficienza Renale Progressiva) project, which involves thirteen Nephrology Hospital Units in Emilia-Romagna (Italy). This model identified seven subgroups with specific combinations of baseline characteristics that were associated with a differential estimated glomerular filtration rate (eGFR) annual decline, but the model's ability to predict mortality and renal replacement therapy (RRT) has not been established yet. METHODS: Survival analysis was used to determine whether CT-PIRP subgroups identified in the derivation cohort (n = 2265) had different mortality and RRT risks. Temporal validation was performed in a matched cohort (n = 2051) of subsequently enrolled PIRP patients, in which discrimination and calibration were assessed using Kaplan-Meier survival curves, Cox regression and Fine & Gray competing risk modeling. RESULTS: In both cohorts mortality risk was higher for subgroups 3 (proteinuric, low eGFR, high serum phosphate) and lower for subgroups 1 (proteinuric, high eGFR), 4 (non-proteinuric, younger, non-diabetic) and 5 (non-proteinuric, younger, diabetic). Risk of RRT was higher for subgroups 3 and 2 (proteinuric, low eGFR, low serum phosphate), while subgroups 1, 6 (non-proteinuric, old females) and 7 (non-proteinuric, old males) showed lower risk. Calibration was excellent for mortality in all subgroups while for RRT it was overall good except in subgroups 4 and 5. CONCLUSIONS: The CT-PIRP model is a temporally validated prediction tool for mortality and RRT, based on variables routinely collected, that could assist decision-making regarding the treatment of incident CKD patients. External validation in other CKD populations is needed to determine its generalizability.
