Persistence of Symptoms 15 Months since COVID-19 Diagnosis: Prevalence, Risk Factors and Residual Work Ability.

Background: A proportion of patients' ailments may last after recovering from acute COVID-19, with episodic and systemic symptoms of unclear etiology potentially involving different organs. Study aim: The aim of this study was to investigate the persistence of symptoms 15 months since COVID-19 diagnosis in patients referring to the post-COVID-19 clinic in Trieste (north-eastern Italy). Methods: Two-hundred-forty-seven patients were medically examined between 8 December 2020-6 April 2021, after a median time of 49 days since first positive swab test for SARS-CoV-2. After a median time of 15 months since COVID-19 diagnosis, the same patients were contacted over the phone and investigated by standardized questionnaire collecting information on any persisting symptoms and work ability index (WAI). Four multivariable logistic regression models were fitted to investigate factors associated with persistence of any respiratory, neurological, dysautonomic, or psychiatric symptoms at first (median time 49 days since COVID-19 diagnosis) as well as second (median 15 months since COVID-19 diagnosis) follow up. A multiple linear regression was also employed to investigate factors associated with higher mean WAI, assessed only at second follow up. Additionally, factors associated with persistence of symptoms 200+ days since COVID-19 diagnosis between first and second follow-up were investigated by multivariable Generalized Estimating Equation (GEE). Results: At first follow up (median time of 49 days since COVID-19 diagnosis) symptoms more frequently reported were fatigue (80.2%), shortness of breath (69.6%), concentration deficit (44.9%), headache (44.9%), myalgia (44.1%), arthralgia (43.3%), and anosmia (42.1%). At second follow-up (median time of 15 months since COVID-19 diagnosis) 75% patients returned to their baseline status preceding COVID-19. At first follow up males were less likely to experience neurological (OR = 0.16; 95% CI: 0.08; 0.35) as well as psychiatric (OR = 0.43; 95% CI: 0.23; 0.80) symptoms as compared to females. At first follow up, the risk of neurological symptoms increased also linearly with age (OR = 1.04; 95% CI: 1.01; 1.08) and pre-existing depression was a major risk factor for persisting dysautonomic (aOR = 6.35; 95% CI: 2.01; 20.11) as well as psychiatric symptoms (omitted estimate). Consistently, at second follow up only females experience psychiatric symptoms, whereas males exhibited significantly higher mean WAI (RC = 0.50; 95% CI: 0.11; 0.88). Additionally, neurological symptoms at second follow up were more likely in patients with pre-existing comorbidities (OR = 4.31; 95% CI: 1.27; 14.7). Finally, persistence of symptoms lasting 200+ days since COVID-19 diagnosis increased linearly with age (OR = 1.03; 95% CI 1.01-1.05) and were more likely in patients affected by pre-existing depression (OR = 2.68; 95% CI 1.60; 4.49). Conclusions: Following a median time of 15 months since first positive swab test, 75% patients with symptoms returned to their baseline health status preceding COVID-19. Females had a significantly lower WAI and were more likely to experience psychiatric symptoms at second follow up (15 months since COVID-19 diagnosis). Furthermore, the risk of symptoms persisting 200+ days since COVID-19 diagnosis increased with history of depression, endorsing the hypothesis that long-COVID-19 symptoms may be at least partially explained by pre-existing psychological conditions. Patient rehabilitation and psychological support may therefore play a key role in caring patients with the so called long COVID-19 syndrome.

Microbial Contamination in Hospital Environment Has the Potential to Colonize Preterm Newborns' Nasal Cavities.

Infants born before 28 weeks are at risk of contracting healthcare-associated infections (HAIs), which could be caused by pathogens residing on contaminated hospital surfaces. In this longitudinal study, we characterized by NGS the bacterial composition of nasal swabs of preterm newborns, at the time of birth and after admission to the Neonatal Intensive Care Unit (NICU), comparing it with that of the environmental wards at the time of delivery and during the hospitalization. We characterized the resistome on the samples too. The results showed that environmental microorganisms responsible for HAIs, in particular Staphylococcus spp., Streptococcus spp., Escherichia-Shigella spp., and K. pneumoniae, were detected in higher percentages in the noses of the babies after 13 days of hospitalization, in terms of the number of colonized patients, microorganism amount, and relative abundance. The analysis of nasal bacteria resistome evidenced the absence of resistance genes at the time of birth, some of which appeared and increased after the admission in the NICU. These data suggest that hospital surface microbiota might be transported to respiratory mucosae or other profound tissues. Our study highlights the importance of a screening that allows characterizing the microbial profile of the environment to assess the risk of colonization of the newborn.

[Integrated social and health care supported by home telemonitoring in patients with heart failure: the European SmartCare project in the Friuli Venezia Giulia Region]. / Efficacia delle cure integrate socio-sanitarie supportate dal telemonitoraggio domiciliare nello scompenso cardiaco: il progetto europeo SmartCare in Friuli Venezia Giulia.

BACKGROUND: Home care for patients with chronic diseases and specifically with heart failure (HF) is one of the main challenges of health care for the future. Telemedicine, applied to HF, allows intensive home monitoring of the most advanced patients, improving their prognosis and quality of life. The European SmartCare project was carried out in the Friuli Venezia Giulia (FVG) region with the aim of improving integrated health and social care in patients with chronic non-communicable diseases (CNCD) through home telemonitoring (TM) and promoting self-management and patient empowerment. METHODS: The SmartCare project in FVG was a prospective, randomized and controlled cohort study that enrolled, from November 2014 to February 2016, 201 patients in integrated home care ("usual care" [UC] in our study) to TM (n=100) or UC (n=101). Inclusion criteria were age >50 years, at least 1 CNCD (HF, chronic obstructive pulmonary disease, or diabetes) and 1 missing BADL. There were 19 drop-outs (9%) (12 in the TM arm; 7 in the UC arm; p=NS). All patients were followed by a multiprofessional team and stratified in the short-term pathway (3-6 months; average 4 ± 1 months; n=101), enrolled at discharge from hospitalization, or in the long-term pathway (6-12 months; mean 10 ± 3 months; n=100) for frail/chronic patients already followed in home care. RESULTS: The most frequent main diagnosis was HF (n=108, 54%), followed by diabetes (30%) and chronic obstructive pulmonary disease (16%). A Charlson score ≥3 was present in 75% of cases and over 60% were taking at least 7 drugs. Among the social characteristics of the enrolled population, 55% were living alone or with non-familial caregivers, 62% had primary education and 48% were non-self-sufficient. The days of hospitalization were significantly reduced only in the TM arm of the post-acute pathway (20 days of hospitalization avoided for 10 patient-months of follow-up, p=0.03) and the effect was mainly evident in patients with HF (p=0.02). A significant increase in the number of home accesses and telephone contacts were also documented in the TM group (12.7 and 13.7 more home interventions for 10 patient-months of follow-up; p=0.01 and p=0.002 in the post-acute and chronic pathway, respectively). CONCLUSIONS: The SmartCare-FVG project showed in patients with chronic diseases (mainly HF), in the post-acute phase of the disease, to significantly reduce the days of hospitalization with a limited and sustainable increase in the use of nursing home care resources.

[Update on the subject of epidemiology of blood-transmitted occupational infections]. / Aggiornamenti in tema di epidemiologia delle malattie infettive occupazionali trasmesse per via ematica.

Healthcare workers (HCW) are exposed to many different pathogens, and cases of occupational infection have been reported involving the vast majority of known and emerging agents. The risk is present during all the phases of patient care and manipulation of biologic materials, and the implementation of Standard Precautions--and biosafety level 2 measures in the laboratory--and Transmission-Based Precautions in all health settings represents the necessary preventive intervention required by law. Percutaneous exposures represent an extremely frequent event in healthcare facilities; among the many pathogens acquired through this type of exposure, those of highest concern due to the frequency of exposure are HIV, HBV and HCV. Over the last 10 years, though the risk of exposure is still not negligible, occupational infection with HBV has become a rare event; conversely, the incidence of acute C hepatitis became significantly higher among HCW (1,6 per 100.000 inhabitants) with respect to the general population (0,6), with a seroconversion rate following an occupational exposure between 0,5% and 1,8%; finally, reports of occupational HIV infection have decreased, probably also as a secondary beneficial effect of antiretroviral treatment in patients and post-exposure prophylaxis in HCW. The Studio Italiano Rischio Occupazionale da HIV (SIROH) documented from 1986 to 2009 one occupational HBV case, 6 HIV cases (the last one in 2007) and 32 HCV cases. In Europe, the Directive 2010/32/EU approved on May 10 2010 requires Member State to implement within three years a global strategy to prevent occupational exposures in the healthcare setting, particularly with respect to needlestick and sharp injuries, including the adoption, based on risk assessment, of devices incorporating safety features. In Italy the introduction of these devices, according to data collected by the SIROH, showed the possibility to decrease percutaneous exposures by 75%, an effect sustained over time if supported by information, education and training.
