Obesity as a risk factor for hospitalization in COronaVirus Disease-19 (COVID-19) patients: Analysis of the Tuscany regional database.

BACKGROUND AND AIMS: Aim of the present study is to determine the role of obesity as a risk factor for COronaVirus Disease-19 (COVID-19) hospitalization. METHODS AND RESULTS: This observational study was performed using Istituto Superiore di Sanità (ISS) Tuscany COVID-19 database by the Agenzia Regionale Sanità (ARS), including all COVID-19 cases registered until April 30th, 2020, with reported information on chronic diseases. The principal outcome was hospitalization. An age and gender-adjusted logistic regression model was used to assess the association of clinical and demographic characteristics with hospitalization. Further multivariate models were applied. Of 4481 included subjects (36.9% aged over 70 years), 1907 (42.6%) were admitted to hospital. Obesity was associated with hospitalization after adjusting for age and gender. The association of obesity with hospitalization retained statistical significance in a fully adjusted model, including possible confounders (OR: 2.99 [IC 95% 2.04-4.37]). The effect of obesity was more evident in younger (<70 years) than in older (≥70 years) subjects. CONCLUSIONS: The present data confirm that obesity is associated with an increased risk of hospitalization in patients with COVID-19. Interestingly, the association of obesity with hospitalization was greater in younger (<70 years) patients.

Caring for nursing home residents with COVID-19: a "hospital-at-nursing home" intermediate care intervention.

BACKGROUND: Nursing home (NH) residents have been dramatically affected by COVID-19, with extremely high rates of hospitalization and mortality. AIMS: To describe the features and impact of an assistance model involving an intermediate care mobile medical specialist team (GIROT, Gruppo Intervento Rapido Ospedale Territorio) aimed at delivering "hospital-at-nursing home" care to NH residents with COVID-19 in Florence, Italy. METHODS: The GIROT activity was set-up during the first wave of the pandemic (W1, March-April 2020) and became a structured healthcare model during the second (W2, October 2020-January 2021). The activity involved (1) infection transmission control among NHs residents and staff, (2) comprehensive geriatric assessment including prognostication and geriatric syndromes management, (3) on-site diagnostic assessment and protocol-based treatment of COVID-19, (4) supply of nursing personnel to understaffed NHs. To estimate the impact of the GIROT intervention, we reported hospitalization and infection lethality rates recorded in SARS-CoV-2-positive NH residents during W1 and W2. RESULTS: The GIROT activity involved 21 NHs (1159 residents) and 43 NHs (2448 residents) during W1 and W2, respectively. The percentage of infected residents was higher in W2 than in W1 (64.5% vs. 38.8%), while both hospitalization and lethality rates significantly decreased in W2 compared to W1 (10.1% vs 58.2% and 23.4% vs 31.1%, respectively). DISCUSSION: Potentiating on-site care in the NHs paralleled a decrease of hospital admissions with no increase of lethality. CONCLUSIONS: An innovative "hospital-at-nursing home" patient-centred care model based on comprehensive geriatric assessment may provide a valuable contribution in fighting COVID-19 in NH residents.

Analysis of the excess mortality and factors associated with deaths from COVID-19 versus other causes in Central Tuscany (Italy) in 2020.

OBJECTIVES: to assess the extent of the excess mortality from all causes in 2020 compared to 2015-2019 in Central Tuscany (Italy) as a proxy to estimate COVID-19-related excess mortality and to identify demographic and clinical differences between subjects who died from COVID-19 and those who died from other causes in 2020. DESIGN: descriptive analysis of the temporal trend of general mortality. SETTING AND PARTICIPANTS: the study population is represented by the 1.6 million residents living in the territory of the Central Tuscany Healthcare Authority in Central Italy, i.e., little less than half of the population of Tuscany, in an area of just over one fifth of the entire region, where the provinces of Florence, Pistoia, and Prato are comprised. MAIN OUTCOME MEASURES: using the Italian National Resident Population Registry (ANPR) as a source of mortality data, standardized mortality ratios with 95% confidence intervals were calculated to compare the number of deaths in 2020 with the number of deaths expected on the basis of mortality data from 2015 to 2019. Furthermore, after record linkage with data from the integrated surveillance of cases of SARS-CoV-2 virus infection and with the MaCro dataset of comorbidities, the characteristics of subjects who died from COVID-19 were compared with those of patients who died from other causes using a multivariate logistic regression model; odds ratios with 95% confidence intervals were calculated. RESULTS: a statistically significant excess mortality was observed during the first pandemic wave in March and April, and during the second wave in the fall; it ranged between +9% in March and +51% in November. On the contrary, in January, February, and May, all-cause mortality was significantly lower than in previous years. The male gender, dyslipidaemia, and dementia were positively associated with death from COVID-19 rather than from all other causes. On the contrary, heart failure and recent tumours were more represented among deaths from other causes. CONCLUSIONS: much of the over-mortality observed in spring is attributable to the harvesting effect COVID-19 exerted on a segment of population with serious underlying chronic conditions and who in the previous months had survived a mild winter and a flu season of medium intensity. In the second pandemic wave, in autumn, the impact of both direct and indirect effects of COVID-19 was substantially higher. Consistently with the available evidence, death from COVID-19 was related to the male gender and to clinical conditions such as dyslipidaemia and dementia.

Differential Network Analysis Reveals Metabolic Determinants Associated with Mortality in Acute Myocardial Infarction Patients and Suggests Potential Mechanisms Underlying Different Clinical Scores Used To Predict Death.

We present here the differential analysis of metabolite-metabolite association networks constructed from an array of 24 serum metabolites identified and quantified via nuclear magnetic resonance spectroscopy in a cohort of 825 patients of which 123 died within 2 years from acute myocardial infarction (AMI). We investigated differences in metabolite connectivity of patients who survived, at 2 years, the AMI event, and we characterized metabolite-metabolite association networks specific to high and low risks of death according to four different risk parameters, namely, acute coronary syndrome classification, Killip, Global Registry of Acute Coronary Events risk score, and metabolomics NOESY RF risk score. We show significant differences in the connectivity patterns of several low-molecular-weight molecules, implying variations in the regulation of several metabolic pathways regarding branched-chain amino acids, alanine, creatinine, mannose, ketone bodies, and energetic metabolism. Our results demonstrate that the characterization of metabolite-metabolite association networks is a promising and powerful tool to investigate AMI patients according to their outcomes at a molecular level.

Blood pressure and long-term mortality in older patients: results of the Fiesole Misurata Follow-up Study.

BACKGROUND: Optimal blood pressure (BP) control can prevent major adverse health events, but target values are still controversial, especially in older patients with comorbidities, frailty and disability. AIMS: To evaluate mortality according to BP values in a cohort of older adults enrolled in the Fiesole Misurata Study, after a 6-year follow-up. METHODS: Living status as of December 31, 2016 was obtained in 385 subjects participating in the Fiesole Misurata Study. Patients' characteristics were analysed to detect predictors of mortality. At baseline, all participants had undergone office BP measurement and a comprehensive geriatric assessment. RESULTS: After a 6-year follow-up, 97 participants had died (25.2%). After adjustment for comorbidities and comprehensive geriatric assessment, mortality was significantly lower for SBP 140-159 mmHg as compared with 120-139 mmHg (HR 0.54, 95% CI 0.33-0.89). This result was also confirmed in patients aged 75 + (HR 0.49, 95% CI 0.29-0.85), and in those with disability (HR 0.36, 95% CI 0.15-0.86) or taking antihypertensive medications (HR 0.49, 95% CI 0.28-0.86). DISCUSSION: An intensive BP control may lead to greater harm than benefit in older adults. Indeed, the European guidelines recommend caution in BP lowering in older patients, especially if functionally compromised, to minimize the risk of hypotension-related adverse events. CONCLUSIONS: After a 6-year follow-up, mortality risk was lower in participants with SBP 140-159 mmHg as compared with SBP 120-139 mmHg, in the overall population and in the subgroups of subjects aged 75 + , with a disability or taking anti-hypertensive medications.

[Chronic diseases and risk of symptomatic COVID-19: results of a case-population study on a sample of patients in the Local Health Unit 'Toscana Centro' (Tuscany Region, Central Italy)]. / Malattie croniche e rischio di ammalarsi di COVID-19 sintomatica: risultati di uno studio case-population su un campione di casi in AUSL Toscana Centro.

BACKGROUND: the COVID-19 pandemic represents a challenge for health systems around the world, with just under 10,000 cases in Tuscany Region (Central Italy) and about 4,500 in the Local Health Unit (LHU) 'Toscana Centro', updated on 11 May 2020. The risk factors reported are several, including age, being male, and some chronic diseases such as hypertension, diabetes, respiratory and cardiovascular diseases. However, the relative importance of chronic diseases is still to be explored. OBJECTIVES: to evaluate the role of chronic diseases on the risk to develop clinically evident (at least mild symptomatic) forms of SARS-CoV-2 infection in the population of the LHU Toscana Centro. DESIGN: case-population study. SETTING AND PARTICIPANTS: 'case' is a subject with SARS-CoV-2 positive swab with at least mild clinical status, who lives in the LHU Toscana Centro area; 'controls' are all people residing in the LHU Toscana Centro area at 1 January 2020. People aged under 30 and patients living in nursing care homes are excluded from the analysis. MAIN OUTCOME MEASURES: the analysis assesses the effect of gender, age, neoplasm, and the main chronic diseases on the onset of an infection with at least mild symptoms by calculating odds ratios (OR) by multivariate logistic regression models (to produce adjusted OR by potential confounders). RESULTS: among the 1,840 cases, compared to the general population, the presence of males and over-60-year-old people is greater. Almost all the considered chronic diseases are more frequent among the cases, compared to the general population. A chronic patient has a 68% greater risk to be positive with at least mild symptoms. Many of the considered diseases show an effect on the risk of getting COVID-19 in a symptomatic form, which remains even adjusting by other comorbidities. The main ones include heart failure, psychiatric disorders, Parkinson's disease, and rheumatic diseases. CONCLUSIONS: these results confirm evidence already shown in other studies on COVID-19 patients and add information on the chronic diseases attributable risk in the population, referred to the symptomatic forms and adjusted by age, gender or the possible copresence of more diseases. These risk estimates should guide prevention interventions by health services in order to protect the chronic patients affected by the pathologies most at risk.

NMR-based metabolomics identifies patients at high risk of death within two years after acute myocardial infarction in the AMI-Florence II cohort.

BACKGROUND: Risk stratification and management of acute myocardial infarction patients continue to be challenging despite considerable efforts made in the last decades by many clinicians and researchers. The aim of this study was to investigate the metabolomic fingerprint of acute myocardial infarction using nuclear magnetic resonance spectroscopy on patient serum samples and to evaluate the possible role of metabolomics in the prognostic stratification of acute myocardial infarction patients. METHODS: In total, 978 acute myocardial infarction patients were enrolled in this study; of these, 146 died and 832 survived during 2 years of follow-up after the acute myocardial infarction. Serum samples were analyzed via high-resolution 1H-nuclear magnetic resonance spectroscopy and the spectra were used to characterize the metabolic fingerprint of patients. Multivariate statistics were used to create a prognostic model for the prediction of death within 2 years after the cardiovascular event. RESULTS: In the training set, metabolomics showed significant differential clustering of the two outcomes cohorts. A prognostic risk model predicted death with 76.9% sensitivity, 79.5% specificity, and 78.2% accuracy, and an area under the receiver operating characteristics curve of 0.859. These results were reproduced in the validation set, obtaining 72.6% sensitivity, 72.6% specificity, and 72.6% accuracy. Cox models were used to compare the known prognostic factors (for example, Global Registry of Acute Coronary Events score, age, sex, Killip class) with the metabolomic random forest risk score. In the univariate analysis, many prognostic factors were statistically associated with the outcomes; among them, the random forest score calculated from the nuclear magnetic resonance data showed a statistically relevant hazard ratio of 6.45 (p = 2.16×10-16). Moreover, in the multivariate regression only age, dyslipidemia, previous cerebrovascular disease, Killip class, and random forest score remained statistically significant, demonstrating their independence from the other variables. CONCLUSIONS: For the first time, metabolomic profiling technologies were used to discriminate between patients with different outcomes after an acute myocardial infarction. These technologies seem to be a valid and accurate addition to standard stratification based on clinical and biohumoral parameters.

Assessment of a structured management pathway for patients referred to the Emergency Department for syncope: results in a tertiary hospital.

AIMS: High hospitalization rates (39-58% in the literature) of patients admitted to Emergency Department (ED) for transient loss of consciousness (T-LOC) suspected for syncope are still an unresolved issue. The presence of an Observation Unit has reduced hospital admissions and the duration of hospitalization in controlled studies, and a Syncope Unit (SU) in the hospital may reduce hospitalization and increase the number of diagnoses in patients with T-LOC. We assessed the effect of a structured organization on hospitalization rate and outcome. METHODS AND RESULTS: Consecutive patients referred to the ED for a T-LOC of a suspected syncopal nature as the main diagnosis were included. The ED physician was trained to choose between: hospital admission (directly or after short observation); discharge after short (<48-h) observation; discharge on a fast track to the SU; and direct discharge without any further diagnostics. From January to June 2010, 362 patients were evaluated in the ED: 29% were admitted, 20% underwent short observation in the ED, 20% were referred to the SU, and 31% were directly discharged. Follow-up data were available on 295 patients who were discharged alive: of these, 1 (0.3%) previously hospitalized patient died within 30 days and 16 (5.4%) died within 1 year. Death rates were 12.9, 3.3, 0, and 2.5% among admitted, observation, SU, and ED-discharged patients, respectively. No death could be directly attributed to T-LOC. Re-admission within 1 year for any cause occurred in 72 (24%) patients; re-admission rates were 45.9, 19.3, 11.5, and 18.0% among admitted, observation, SU, and ED-discharged patients, respectively. CONCLUSIONS: The availability of short observation and a SU seems to reduce the hospitalization rate compared with previous reported historical reports from our and other centres. Most deaths during follow-up occurred in patients who had been hospitalized. High rates of re-admission to the ED within 1 year are still an issue.

Gender differences in statin prescription rates, adequacy of dosing, and association of statin therapy with outcome after heart failure hospitalization: a retrospective analysis in a community setting.

PURPOSE: The existence of gender differences in the management of statin therapy among patients with chronic heart failure (HF) is still poorly investigated. We aimed at exploring the effect of gender on statin prescription rates and adequacy of dosing and on the association between statin therapy and all-cause 1-year mortality, after HF hospitalization in a community setting. METHODS: Statin prescription rates, adequacy of dosing (estimated as a PDD/DDD ratio >0.80), and 1-year mortality were retrospectively assessed in 2088 consecutive patients discharged from 5 local community hospitals with a definite diagnosis of HF after a mean length of stay of 7.6 days. The effect of gender was explored using multivariable logistic and Cox analyses adjusting to confounders. RESULTS: Women showed a lower statin prescription rate (25.7 vs 35.3%, P < 0.0001) and a lower prevalence of adequate statin dose (32.6 vs 42.3%, P < 0.0001) than men. Female gender was independently associated with a 24% lower probability of statin prescription and a 48% higher probability of inadequate statin dose. Statin prescription and adequacy of dosing were associated with 35 and 44% decreases in the risk of 1-year mortality, respectively, irrespective of gender. A nested case/control analysis confirmed that adequate statin dose was associated with 48% lower 1-year mortality, again without interaction with gender. CONCLUSIONS: In patients with chronic HF, female gender is independently associated with lower statin prescription rates and higher probability of inadequate dose. Statin therapy in these subjects is associated with improved 1-year survival in both men and women. This prognostic benefit is not affected by gender.

[Use of regional health administrative databases to estimate the prevalence of mental disorders and health service utilization in a Local Health Unit of Tuscany Region (Central Italy)]. / Uso dei flussi informativi sanitari regionali per stimare la prevalenza dei disturbi mentali e il ricorso ai servizi sanitari nella popolazione di una Asl della Toscana.

OBJECTIVES: prevalence estimation of mental disorders and mental health services (SSM) utilization in 2011, using the administrative regional health databases (hospital discharge records, pharmaceutical prescriptions) and the Regional Database on Mental Health (SIRSM). STUDY DESIGN: descriptive population-based study. SETTING AND PARTICIPANTS: residents in a Local Health Unit (Florence) of Tuscany Region (Central Italy) who have access to SSM and/or to hospital departments of psychiatry/neuropsychiatry and/ or have psycholeptic/psychoanalectic prescriptions. MAIN OUTCOME MEASURES: frequencies; crude and age-standardized prevalence of patients who have access to the SSM or have admission to a hospital psychiatric ward or have psycholeptic/psychoanalectic prescriptions. RESULTS: a high prevalence (11.2%) of residents had at least one contact with health services for mental health problems, mostly (84%) for drug prescriptions only (20% of patients had a unique prescription during 2011). Depression is the most important disease (9.8% of residents had at least one prescription of antidepressants); mood disorders are the most common cause of adult access to SSM (35%-36%) and hospitalization in psychiatric ward (about 36% of admissions). Only a small proportion (about 15%) of patients with mental health problems have access to the SSM, presumably those with more severe diseases. CONCLUSIONS: results show that the information of the SIRSM database, together with pharmaceutical prescriptions (psycholeptic/ psychoanalectic) and hospitalisation in psychiatric ward, is a useful tool for assessing the prevalence of mental health problems in a population.

Premature ovarian insufficiency in young girls: repercussions on uterine volume and bone mineral density.

STUDY OBJECTIVE: To evaluate biological differences among young subjects with premature ovarian insufficiency (POI) commencing at different stages of life. DESIGN: Retrospective observational study. SETTING: Careggi University Hospital Participants: One hundred sixty-two females aged between 15 and 29 years with premature ovarian insufficiency. METHODS: Data were collected as a retrospective chart review of baseline evaluation at diagnosis of premature ovarian insufficiency (POI). About 162 participants were divided into four groups based on gynecological age. Two primary outcome variables (uterine development and bone mineral density (BMD)) were analyzed in terms of differences among groups and in a multivariate logistic regression analysis. RESULTS: Uterine development was clearly jeopardized when estrogen insufficiency started at a very young age. Total body BMD showed significant differences among the four groups studied, clearly corresponding to the duration of ovarian function. Data were discussed in relation to the choice of hormone replacement therapy regimens.

[Trends in occurrence, treatment, and outcomes of acute myocardial infarction in Tuscany Region (Central Italy), 1997-2010]. / Trend temporali di occorrenza, trattamento ed esiti dell'infarto miocardico acuto in Toscana, 1997-2010.

OBJECTIVES: to describe trends in attack rate, treatment, and outcomes of acute myocardial infarction (AMI) in Tuscany Region (Central Italy). DESIGN: population-based epidemiological study using the Tuscany Acute Myocardial Infarction Registry. SETTING AND PARTICIPANTS: cases have been identified by record linkage between the hospital discharge database and the mortality registry, and divided into hospitalised AMI (1997-2012) and out-of-hospital coronary deaths (1997-2010). Details on hospitalised cases based on the presence/absence of ST-segment elevation (STEMI / NSTEMI) can be detected for the period 2001-2012. MAIN OUTCOMEMEASURES: distribution by calendar time, gender, and type of event of absolute frequencies, age-standardised attack rates (per 100,000; standard Tuscany population, 2001) and percentages (standard: total hospitalised cases in 2011) of invasive cardiac procedures and 28-day case fatality in hospitalised cases. RESULTS: a reduction in both out-of-hospital coronary deaths and STEMI hospitalisations (attack rates, respectively, - 2.3% and -3.9% in males, -3.3% and -4.1% in females) and an increase in NSTEMI hospitalisations (+13.1% in males and +13.3% in females) were shown. The use of invasive cardiac procedures (PCI, coronary angiography) in hospitalised cases shows a considerable increase over time both in STEMI and in NSTEMI. The proportion, however, always remains lower in the whole period after the age of 70 and in women. The short term prognosis in hospitalised AMI cases shows an improvement over time, which, however, disappears when stratified by type of AMI. This trend is mainly related to the different weight that STEMI and NSTEMI have on incidence over time (increase in attack rates for NSTEMI and reduction for STEMI, with worst prognosis). CONCLUSIONS: results confirm the important changes in epidemiology, clinical presentation, and treatment of acute coronary disease in Tuscany, previously identified in the international literature. Differences in coronary reperfusion treatment of hospitalised cases still persist by age and gender. Additional efforts are needed to ensure equity in access to the best treatment for AMI.

Effects of the implementation of the dynamic silver code in the emergency department.

BACKGROUND: Older persons accessing the Emergency Department (ED) spend more time and are at increased risk of poor outcomes. The Dynamic Silver Code (DSC), based on administrative data, predicts mortality of 75+ subjects visiting the ED. OBJECTIVE: To evaluate the effects of the implementation of the DSC in the ED. METHODS: A pre-post comparison was conducted in the ED of a community hospital in Florence, Italy before and after the DSC was fully implemented. In the post-DSC phase, a clinical decision tree was applied: patients at low-mild risk (DSC class I and II) were assigned to Internal Medicine, those at moderate risk (class III) to Geriatrics, and those at high risk (class IV) required geriatric consultation before assignment. Outcome measures were ED length of stay (LOS) and, in patients admitted to Geriatrics, weight of the Diagnosis Related Groups (DRG), hospital LOS, and mortality. RESULTS: 7,270 patients were enrolled in the pre-DSC and 4,725 in the post-DSC phase. ED LOS decreased from a median of 380 [206, 958] in the pre-DSC to 318 [178, 655] min in the post-DSC period (p<0.001). Class III represented the largest share of admissions to Geriatrics in the post-DSC period (57.7 % vs. 38.3 %; p<0.001). In patients admitted to Geriatrics, hospital LOS decreased by one day (p = 0.006) between the two study periods, with greater DRG weight and comparable mortality. CONCLUSIONS: Application of the DSC seemed to ease patient flow and to reduce LOS of older patients in the ED and increased appropriateness of admissions to Geriatrics.

Ozone short-term exposure and acute coronary events: a multicities study in Tuscany (Italy).

OBJECTIVE: Many studies have investigated the potential role of ozone exposure in cardiovascular mortality and morbidity. The effects on specific cardiovascular outcome and the role of individual susceptibility are less studied. This paper focuses on the short-term effects of ozone on acute coronary events and it investigates comorbidities as indicators of personal susceptibility. SETTING AND PATIENTS: This study was conducted in five urban areas of the Tuscany region (Italy) covering the period January 2002-December 2005. Air quality and meteorological data from urban background monitoring sites were collected. Hospital admissions for acute myocardial infarction and out-of-hospital coronary deaths were extracted from administrative database. DESIGN: Both time series and case-crossover designs were applied. The confounding effects of some time-dependent variables, such as temperature, were taken into account. Some potential susceptibility factors were investigated. Pooled estimates were derived from random-effect meta-analysis. RESULTS: During the warm season 4555 hospitalized acute myocardial infarctions and 1931 out-of-hospital coronary deaths occurred. Authors estimated a 6.3% (95% confidence interval, 1.2%, 11.7%) increase in out-of-hospital coronary deaths for a 10 µg/m3 increase in ozone (lag 0-5). Results also suggested higher risks for females, elderly, and patients previously hospitalized for cerebrovascular and artery diseases. CONCLUSIONS: This study adds further evidence to the relation between cardiovascular diseases and ozone exposure, showing an adverse effect on out-of-hospital coronary deaths, but not on hospitalized acute myocardial infarctions. Some susceptible subgroups, such as females, elderly, and patients affected by some chronic diseases, are likely to be at major risk.

[Population-based registries of Acute Myocardial Infarction in Italy]. / La registrazione su base di popolazione dell'incidenza dell'infarto miocardico acuto in Italia.

The purpose of this study is to discuss some issues related to changes in the diagnostic detection of acute myocardial infarction (AMI) and to present international and national experiences of registration of the major coronary events (MONICA project, EUROCISS project, National Register of the major coronary events, experiences based on the use of current health databases). This paper does not take into account activities aimed to assess quality of care given to patients with AMI and/or acute coronary syndromes (ACS), developed in clinical settings or using current data. In Italy there have been few experiences in registration of AMI and/or ACS, some of them are still in progress. Despite the importance of ACS in terms of public health and health care resources utilisation, these initiatives have not led to a registration network with consistent and comparable recording criteria. This problem is very relevant in relation to the significant changes that have occurred in the past, and which continue to occur, in diagnostic and therapeutic criteria. Currently, the geographic and temporal trends of coronary heart disease are only provided by the current data of hospitalization and mortality, with the limits that these databases involve. The presence of ACS registries could provide standardized diagnostic criteria and comparability of results between different areas of the Country, contributing to a better understanding of the epidemiological dynamics of AMI in Italy.

[Mortality aftermyocardial infarction: when the health local organization network has a role in interpreting themarkers of theNational Agency for RegionalHealth Services]. / Mortalità dopo infarto miocardico: quanto la rete locale di organizzazione dell'assistenza conta nell'interpretazione di indicatori dell'Agenzia nazionale per i servizi sanitari regionali.

The Italian National Outcome Programme has assessed the performance of Italian hospitals regarding several clinical performance indicators, including 30-daymortality after admission for acute myocardial infarction. Risk adjustment was obtained using demographic and comorbidity data based on the hospital discharge databases in the index admission, as well as in those of the previous two years. Noticeably, the ICD-9-CM 410.7* classification coding for NSTEMI (Non-ST elevation myocardial infarction)myocardial infarction, i.e. the less severe form, was not used, due to known variability in its use. We found that hospital-specific adjusted relative risk of death versus the national mean, as computed by the programme, is negatively associated with the proportion of NSTEMI infarctions at each Tuscan and Florentine hospital, coherently with the hypothesis of a selection by the emergency network, which addresses STEMI (ST elevation myocardial infarction) patients to hospitals offering haemodynamic laboratory with reperfusive services. Individual level clinical data of 3,200 patients in the AMI-Florence study in the period April 2008-March 2010 found that ICD-9-CM410.7* is underused. The analysis based on hospital discharge diagnoses (410.7* vs. other 410* codes) cannot explain differences in mortality among Florentine hospitals, as opposed to the use of a classification of myocardial infarction type (STEMI vs. NSTEMI) based on clinical data collected in AMI-Florence.

Metabolic and cardiovascular outcomes of fatherhood: results from a cohort of study in subjects with sexual dysfunction.

INTRODUCTION: Previous cross-sectional and longitudinal studies reported a negative correlation between fatherhood and testosterone (T) levels, likely due to a centrally mediated downregulation of the hypothalamic-pituitary-gonadal axis. Moreover, epidemiological data indicate that fatherhood might affect metabolic and cardiovascular outcomes, although different results have been reported. Up to now, no studies have evaluated these associations in a population of men seeking treatment for sexual dysfunction (SD). AIM: To explore biological and clinical correlates of number of children (NoC) and its possible associations with forthcoming major cardiovascular events (MACE) in a sample of men with SD. METHODS: A consecutive series of 4,045 subjects (mean age 52 ± 13.1 years old) attending the Outpatient Clinic for SD was retrospectively studied. A subset of the previous sample (N = 1,687) was enrolled in a longitudinal study. MAIN OUTCOME MEASURES: Information on MACE was obtained through the City of Florence Registry Office. RESULTS: Among patients studied, 31.6% had no children, while 26.3% reported having one child, 33.4% two, and 8.8% three or more children. Although fatherhood was negatively related with follicle-stimulating hormone levels and positively with testis volume, we found a NoC-dependent, stepwise decrease in T plasma levels, not compensated by a concomitant increase in luteinizing hormone. NoC was associated with a worse metabolic and cardiovascular profile, as well as worse penile blood flows and a higher prevalence of metabolic syndrome (MetS). In the longitudinal study, after adjusting for confounders, NoC was independently associated with a higher incidence of MACE. However, when the presence of MetS was introduced as a further covariate, the association was no longer significant. CONCLUSIONS: This study supports the hypothesis that bond maintenance contexts and fatherhood are associated with an adaptive downregulation of the gonadotropin-gonadal axis, even in a sample of men with SD. Moreover, our data suggest that NoC predicts MACE, most likely because of an unfavorable, lifestyle-dependent, parenthood-associated behavior.

Morbidity and mortality analysis in general surgery operations. Is there any room for improvement?

BACKGROUND: The aim of this work is to examine the performance of surgeries, by evaluating the results. The evaluation of the results, with particular attention to complications, is the corner stone to identify the causes leading to correction of any predisposing factors and reducing risks, to improve quality of care. METHODS: We performed a retrospective analysis of 952 consecutive patients who had elective or emergency surgery from November 1, 2018, to October 31, 2019. We classified surgical intervention according to their complexity. The Clavien Dindo classification was used to categorize the complications. We performed a stepwise multivariate logistic-regression analysis, with the presence of postoperative complications as dependent variable and age, gender, BMI, ASA, type of surgery procedures, complexity of surgery, operative time as covariates. RESULTS: A total of 952 surgical procedures were included in this study. Abdominal procedures were the most frequent type of surgery performed (52.1%). Postoperative complications occurred in 120 surgical procedures (12.6%), these are related to the increase of the ASA score and the longer average operative time, with an increase of developing complication of 5% for each additional 10 minutes of surgery. CONCLUSIONS: Many factors influence postoperative morbidity and mortality. Particular attention was due to complication's evaluation, about all in abdominal surgery and high complexity procedures. We argue that key factors which influence the favorable surgical outcome are compliance with standardized safety procedures, volume of activity of the structure, presence of interdisciplinary care groups, and ability of health professionals in recognizing and promptly treating complications.

COVID-19, Vulnerability, and Long-Term Mortality in Hospitalized and Nonhospitalized Older Persons.

OBJECTIVE: Studies suggesting that vulnerability increased short-term mortality in older patients with COVID-19 enrolled hospitalized patients and lacked COVID-negative comparators. Aim of this study was to examine the relationship between frailty and 1-year mortality in older patients with and without COVID-19, hospitalized and nonhospitalized. DESIGN: Cohort study. SETTING AND PARTICIPANTS: Patients over 75 years old accessing the emergency departments (ED) were identified from the ED archives in Florence, Italy. METHODS: Vulnerability status was estimated with the Dynamic Silver Code (DSC). COVID-19 hospital discharges (HC+) were compared with non-COVID-19 discharges (HC-). Linkage with a national COVID-19 registry identified nonhospitalized ED visitors with (NHC+) or without COVID-19 (NHC-). RESULTS: In 1 year, 48.4% and 33.9% of 1745 HC+ and 15,846 HC- participants died (P < .001). Mortality increased from 27.5% to 64.0% in HC+ and from 19.9% to 51.1% in HC- across DSC classes I to IV, with HC+ vs HC- hazard ratios between 1.6 and 2.2. Out of 1039 NHC+ and 18,722 NHC- participants, 18% and 8.7% died (P < .001). Mortality increased from 14.2% to 46.7% in NHC+ and from 2.9% to 26% in NHC- across DSC; NHC+ vs NHC- hazard ratios decreased from 5.3 in class I to 2.0 in class IV. CONCLUSIONS AND IMPLICATIONS: In hospitalized older patients, mortality increases with vulnerability similarly in the presence and in the absence of COVID-19. In nonhospitalized patients, vulnerability-associated excess mortality is milder in individuals with than in those without COVID-19. The disease reduces survival even when background risk is low. Thus, apparently uncomplicated patients deserve closer clinical monitoring than commonly applied.

Estimating Prognosis and Frailty in Persons Aged ≥75 Years in the Emergency Department: Further Validation of Dynamic Silver Code.

OBJECTIVES: To assess concurrent validity of the Dynamic Silver Code (DSC), a tool based on administrative data that predicts prognosis in older adults accessing the emergency department (ED), in terms of association with markers of poor functional and cognitive status. DESIGN: Cross-sectional. SETTING AND PARTICIPANTS: Data were obtained in the AIDEA study, which enrolled a cohort of ≥75-year-old patients, accessing the ED of 2 hospitals in Florence, Italy. METHODS: The DSC score and classes (I to IV, corresponding to an increasing risk of death) were obtained from administrative data. Information on health and functional status prior to ED access were collected from face-to-face, direct, or proxy interviews. The 4AT test was administered to screen for possible delirium. Bivariate comparisons of the prevalence of each functional and cognitive marker across 4 DSC classes were performed. Multinomial logistic regression was used to assess the multivariable risk of being in II, III, or IV DSC class vs I. RESULTS: Among 3358 participants (mean age 83 years, men 44%), 32.9%, 30.3%, 19.5%, and 17.2% were in DSC class I, II, III, and IV. Preadmission abnormal functional and cognitive conditions, and delirium in the ED, were increasingly more common from DSC class I through IV (P < .001). In particular, the prevalence of total inability to walk increased from 2.9% (class I) to 23.4% (class IV). In multivariable analyses, this was the strongest predictor of being in progressively worse DSC classes, whereas feeling of exhaustion, reporting of serious falls, weight loss, and severe memory loss or diagnosis of dementia gave some contribution. CONCLUSIONS AND IMPLICATIONS: The ability of the DSC to predict survival in older persons appears to rely on its prevailing association with markers of functional impairment. These results may support clinical use of the tool.
