Microbiologically confirmed infections and antibiotic-resistance in a national surveillance study of hospitalised patients who died with COVID-19, Italy 2020–2021

Background

Patients hospitalised for COVID-19 may present with or acquire bacterial or fungal infections that can affect the course of the disease. The aim of this study was to describe the microbiological characteristics of laboratory-confirmed infections in hospitalised patients with severe COVID-19.

Methods

We reviewed the hospital charts of a sample of patients deceased with COVID-19 from the Italian National COVID-19 Surveillance, who had laboratory-confirmed bacterial or fungal bloodstream infections (BSI) or lower respiratory tract infections (LRTI), evaluating the pathogens responsible for the infections and their antimicrobial susceptibility.

Results

Among 157 patients with infections hospitalised from February 2020 to April 2021, 28 (17.8%) had co-infections (≤ 48 h from admission) and 138 (87.9%) had secondary infections (> 48 h). Most infections were bacterial; LRTI were more frequent than BSI. The most common co-infection was pneumococcal LRTI. In secondary infections, Enterococci were the most frequently recovered pathogens in BSI (21.7% of patients), followed by Enterobacterales, mainly K. pneumoniae, while LRTI were mostly associated with Gram-negative bacteria, firstly Enterobacterales (27.4% of patients, K. pneumoniae 15.3%), followed by A. baumannii (19.1%). Fungal infections, both BSI and LRTI, were mostly due to C. albicans. Antibiotic resistance rates were extremely high in Gram-negative bacteria, with almost all A. baumannii isolates resistant to carbapenems (95.5%), and K. pneumoniae and P. aeruginosa showing carbapenem resistance rates of 59.5% and 34.6%, respectively.

Conclusions

In hospitalised patients with severe COVID-19, secondary infections are considerably more common than co-infections, and are mostly due to Gram-negative bacterial pathogens showing a very high rate of antibiotic resistance.

Need for a competency-based approach for the Public Health Workforce training: the ISS proposal

Issue

The COVID-19 pandemic acted as a catalyst for a reconsidering health care professional workforce (HCPW) competency needed to face future public health challenges, in line with the recent WHO “Global Competency and Outcomes Framework for UHC” document. In this context, in the Italian G20 Presidency framework, the Italian National Institute of Health (ISS), launched a program named “Laboratorium” - recognised in the G20 Declarations of Ministers of Health and Leaders - aimed to the development of training tools suitable for distance learning in whatever context they are placed.

Description of the problem

Common competencies and needs of the HCPW have to be fulfilled through cross-sectional and multilevel training, to overcome the current emergency and be able to face future challenges. The aim is to provide a modular educational approach that is finalized to actively involve the participant: health professionals step in their training pathway according to their knowledge gaps, identify their specific learning objectives and, through a problem-based learning approach, acquire the proper skills for their function and tasks.

Results

We propose a two-tiered approach to training: the development of competence based courses oriented to active learning. A pilot course on Epidemic Intelligence design according to this model is ready to be released. At the same time, a repository of everything available on the web systematically selected from authorised sources by a scientific committee was created to support the training objective. It is characterised by a detailed multilevel tagging that allows an effective modularisation to reach only the content useful for its user.

Lessons

Accessibility to health-related training materials is a required necessity at every level of HCPW. Profiles within healthcare are increasingly heterogeneous and there is a need to focus on disseminating tools that can provide knowledge to address different healthcare scenarios and common purposes.

Key messages

• Future public health challenges underline a need for a competencies-based learning approach in Healthcare Workforce training.

• Italian National Institute of Health propose two methods within the ‘Laboratorium’ project to enable this type of learning: specifically designed courses and a structured document repository.

Excimer laser technology in percutaneous coronary interventions: Cardiovascular laser society's position paper

Excimer Laser Coronary Atherectomy (ELCA) is a well-established therapy that emerged for the treatment of peripheral vascular atherosclerosis in the late 1980s, at a time when catheters and materials were rudimentary and associated with the most serious complications. Refinements in catheter technology and the introduction of improved laser techniques have led to their effective use for the treatment of a wide spectrum of complex coronary lesions, such as thrombotic lesions, severe calcific lesions, non-crossable or non-expandable lesions, chronic occlusions, and stent under-expansion. The gradual introduction of high-energy strategies combined with the contrast infusion technique has enabled us to treat an increasing number of complex cases with a low rate of periprocedural complications. Currently, the use of the ELCA has also been demonstrated to be effective in acute coronary syndrome (ACS), especially in the context of large thrombotic lesions.

The management of the Sars-CoV-2 pandemic in Italy, lessons earnt and reflections for the future

Background:

Italy and especially Lombardy region was the first European Country hit by the covid 19 pandemic, without a proper preparedness plan. Italy’s health-care service is a regionally based National Health Service (NHS) that provides universal coverage, largely free of charge at the point of service. Aim of this paper is to analyse the national and especially the regional strategies put in place to face the pandemic, focusing on the impact of the overlap of the political and health competences among national and regional authority.

Methods:

Italian hygiene and preventive medicine society (SITI) realized a questionnaire submitted to National Institute for Health and regional stakeholder to investigate the response to the epidemic analysing the strategies and actions put in place both by the national and regional governments and the regional health authorities.

Results:

The national survey highlighted several critical points in the management of the covid 19 pandemic in the different regional contexts such as lack of personnel in preventive departments and preparadness.

Conclusions:

Lessons learnt during the pandemic should shape the future of the Italian health service. (www.actabiomedica.it)

A Severe Acute Respiratory Syndrome Coronavirus 2 detection method based on nasal and nasopharyngeal lavage fluid: A pilot feasibility study

OBJECTIVE

Nose and nasopharyngeal swab is the preferred and worldwide-accepted method to detect the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) within the nose and nasopharynx. This method may be linked with possible difficulties, such as patient's discomfort or complications. This article shows a pilot study of SARS-CoV-2 detection with nasal and nasopharyngeal lavage fluids (level of evidence: 3).

METHODS

Nasal lavage fluid was collected from patients who were submitted to SARS-CoV-2 screening test, due to a preceding positive rapid antigen test. A control group was enrolled among health care professionals whose nasopharyngeal swab tested negative. Nasal lavages were performed using isotonic saline solution injected through a nasal fossa. Both lavage fluid and traditional nasopharyngeal swab were analyzed by real-time (RT) PCR and antigenic test.

RESULTS

A total of 49 positive subjects were enrolled in the study. Results of the analysis on lavages and nasopharyngeal swabs were concordant for 48 cases, regardless of the antigenic and molecular test performed. RT-PCR resulted weakly positive at swab in one case and negative at lavage fluid. Among the control group (44 subjects), nasopharyngeal swab and lavage fluid analyses returned a negative result. Sensitivity of the molecular test based on nasal lavage fluid, compared to traditional nasal swab, was 97.7%, specificity was 100%, and accuracy was 98.9%, with high agreement (Cohen's κ, 0.978).

CONCLUSION

Nasal and nasopharyngeal lavages resulted to be highly reliable and well tolerated. A larger series is needed to confirm these results. This approach may potentially represent a valid alternative to the traditional swab method in selected cases.

How can we manage the COVID-19 infodemics? A case study targeted to health workers in Italy

INTRODUCTION

The Istituto Superiore di Sanità (ISS) has been asked for rapid technical and scientific advice to the State and Regions during Sars-CoV-2 pandemic preparedness.

METHODS

An ad hoc Working Group on Scientific Literature updates (WG SL) was set up at ISS (March-May 2020) to screen pre-prints and peer reviewed papers from arXiv, medRxiv, bioRxiv, and Pubmed to provide a real time knowledge and empirical evidence addressed to health-workers.

RESULTS

The WG SL screened a total of 4,568 pre-prints and 15,590 peer reviewed papers, delivered as daily summary report of pre-print selection for ISS President activity in the National Scientific Technical Committee framework and a weekly open access publication (COVID Contents) on peer-reviewed papers of interest for health professionals, monitored by a satisfaction questionnaire.

CONCLUSIONS

Promoting heath literacy, with a cross-cutting approach is a powerful heritage of Public Health Institutes and a proven effective non pharmacological intervention.

COVID-19 and digital competencies among young physicians: are we (really) ready for the new era? A national survey of the Italian Young Medical Doctors Association

BACKGROUND

Digital health (DH) is nowadays fundamental for physicians. Despite the improvement of information and communications technology (ICT), Italian medical doctors' (MDs) education system seems inadequate in this area. Moreover, due to the COVID-19 pandemic, societies are waking up to their limitations. The aim of this paper is to analyze the Italian status quo in DH.

METHODS

The Italian Young Medical Doctors Association (Segretariato Italiano Giovani Medici - SIGM) proposed a web-based survey to assess DH awareness and previous knowledge among young doctors. Investigated areas were: big data, -omics technology and predictive models, artificial intelligence (AI), internet of things, telemedicine, social media, blockchain and clinical-data storage.

RESULTS

A total of 362 participants answered to the survey. Only 13% had experience in big data during clinical or research activities, 13% in -omics technology and predictive models, 13% in AI, 6% had experience in internet of things, 22% experienced at least one telemedicine tool and 23% of the participants declared that during their clinical activities data collection was paper-driven.

CONCLUSIONS

Three categories of MDs, high-tech, low-tech and no-tech, can be identified from the survey-based investigation. Our survey's results indicate an urgent need for integration of pre- and post-graduation training in digital health to provide adequate medical education.

Accelerating the health literacy agenda in Europe

Health literacy can be defined as the knowledge, motivation and competence to access, understand, appraise and apply information to make decisions in terms of healthcare, disease prevention and health promotion. Health literacy is a European public health challenge that has to be taken seriously by policy-makers. It constitutes an emerging field for policy, research and practice. However, recent research has shown that health literacy advancement is still at its infancy in Europe, as reflected in the scarce scientific health literacy literature published by European authors. From a total of 569 articles published until 2011 on this subject, the first author of only 15% of them is from Europe. This article conveys recommendations of different European stakeholders on how to accelerate the health literacy agenda in Europe. A general introduction on the current status of health literacy is provided, followed by two cases applying health literacy in the areas of prevention of communicable diseases and promotion of digital health. The current EU strategies integrating health literacy are listed, followed by examples of challenges threatening the further development of health literacy in Europe. Recommendations as to how European stakeholders involved in research, policy, practice and education can promote health literacy are given. It is vital that the European Commission as well as European Union Member States take the necessary steps to increase health literacy at individual, organizational, community, regional and national levels.

Toxoplasmosis in Kosovo pregnant women

This study presents the initial results of a collaborative project aimed at the evaluation of Toxoplasma seroprevalence in a population of Kosovar pregnant women. The serum samples of 334 pregnant women were tested to detect IgG, IgM, IgG avidity for toxoplasmosis. Data regarding age, occupation, area of origin and education were also obtained for the pregnant women examined; 97/334 (29.4%) resulted positive for IgG antibodies, four of whom (4.1%) were also positive for IgM, (1.2% of the total population examined). All four IgM-positive pregnant women also demonstrated low avidity tests. The rate of IgG seroprevalence found in our study was lower than that observed in various European countries, especially those of western Europe. Conversely, the percentage of recent infections was higher than expected. The higher rate of infections could be the result of a recent toxoplasmosis epidemic in Kosovo, most likely due to the altered hygienic conditions caused by the forced transfer of the ethnic-Albanian population from an area of low (Serbia) to high (Kosovo) toxoplasmosis prevalence.

Prevalence of antibodies to phleboviruses and flaviviruses in Peja, Kosovo

In order to investigate the current and past activity of phlebovirus and flavivirus in Kosovo, a seroprevalence study among 200 blood donors was performed. Positive results were obtained for the phleboviruses TOSV and SFNV, and for a flavivirus of the Japanese Encephalitis group. No positive results for TBEV were observed.

Seroprevalence of HIV, HSV-2, and Treponema pallidum in the Kosovarian population

The objective of this study was to evaluate the seroprevalence of infection with HIV, herpes simplex virus type 2 (HSV-2), and Treponema pallidum (TP) in a Kosovarian population. A cross-sectional study was performed in Peja, Kosovo, from January to March 2005, among 1285 persons recruited at the Peja Hospital. The seroprevalence of HIV, HSV-2, and TP was evaluated, and the viral correlates for each infection were analysed. No HIV-positive cases were found. The seroprevalence of HSV-2 was 20.2%. The factors significantly associated with HSV-2 infection at the multivariate analysis were: female gender (adjusted OR, 1.73; 95% CI 1.24-2.41) and being married (adjusted OR, 1.46; 95% CI 1.06-2.01). Three persons (0.2%) had a positive serology for TP. The only risk factor associated with TP infection was age = 50 y. Our results show a low seroprevalence of HIV infection and TP, and a high seroprevalence of HSV-2 in Kosovo. These findings suggest the need for appropriate surveillance systems, prevention programmes, and information aimed at controlling the spread of HIV and other sexually transmitted infections in this area. Moreover, the circulation of infections acquired through sexual contact may facilitate an increase in the sexually transmitted HIV epidemic in the near future.

Viral hepatitis, HIV, human herpes virus and Treponema pallidum infection in haemodialysis patients from Kosovo, 2005

The serological status of hepatitis viruses and other infectious diseases in the 66 dialysed patients of one haemodialysis unit in Kosovo were studied, comparing the data with a large group of blood donors and out-patients. All dialysed patients were hepatitis A virus (HAV) positive. Prevalence of hepatitis B surface antigen (HBsAg), hepatitis B surface antibodies (anti-HBs), and hepatitis B core antibodies (anti-HBc) was 14 of 66, 21% (95% confidence interval (CI): 12-33%), 5 of 66, 8% (95%CI: 5-22%), and 50 of 66, 76% (95%CI: 64-85%), respectively. Antibodies to hepatitis C virus (anti-HCV) prevalence was 57 of 66, 86% (95%CI: 76-94%). No human immunodeficiency virus (HIV) positive case was found. Prevalence of past herpes simplex virus type 2 (HSV-2) infection was 29% (95%CI: 18-41%). Two patients (3%, 95%CI: 0-10%) were positive for Treponema pallidum and 18% (95%CI: 10-30%) were human herpesvirus 8 (HHV-8) antibody positive. Four hundred and fifty-two subjects were recruited for comparison. Markers of past HAV infection was associated with haemodialysis (Fisher s exact test p-value=0.037). Dialysed patients were at a higher risk of being HBsAg positive than others: the sex- and age-adjusted odds ratio (OR) was 5.18 (95%CI: 1.87-14.32). Anti-HBc positivity was strongly associated with haemodialysis: the sex- and age-adjusted OR was 6.43 (95%CI: 3.22-12-85). Anti-HCV positivity was 86% and 1% in presence and absence of haemodialysis, respectively. The Fisher s exact test for association proved a strong association between haemodialysis and HCV (p-value<0.0001). The OR for association between haemodialysis and HSV-2 positivity was 3.20 (95%CI: 1.46-7.00). Significant associations were also observed between haemodialysis status and antibodies to Treponema pallidum (Fisher s exact test p-value=0.044). In Kosovo, the prevalence of viral hepatitis infection and other viral infections and Treponema pallidum among dialysed patients is high, indicating major ongoing nosocomial transmission.

Contamination of drinking water sources during the rainy season in an urban post-conflict community in Guinea Bissau: implications for sanitation priority

Since the 1998 civil warcholera outbreaks and waterborne infections have been a major cause of morbidity and mortality during the rainy season in Guinea Bidsau. Our survey aims at: (1) describing the distribution, characteristics and use of water sources and sewage facilities in a central area of the capital city of Bissau; (2) determining the microbiological quality of drinking water during the rainy season. After mapping of the Cuntum 3 study area, water sources' and latrines' location, characteristics and use were determined by visual inspection and interviews with householders. Microbiological analyses were peformed from water sources for evaluation of total Coliforms, E. coli, Enterococcus faecalis. Twelve water sources (9 wells, 3 taps) and 15 latrines were identified and used by 444 inhabitants. Water sources and latrines were at less than 5 meters distance apart. Wells were self-built, hand-dug, shallow (4-6 meters), unprotected. Taps were located outdoor. Latrines were self-built, open air, unprotected. None of the houses had a bathroom. Maintenance of wells, taps and latrines is not performed on regular basis and well's handling habits are not safe. Well and tap water showed heavy faecal contamination with more than 1000 CFU/100 ml. The contamination of drinking water in Bissau due to poor construction, maintenance and improperuse ten years after the civil war, demonstrates the need to allocate resources after conflicts in the area of water and sanitation. Both should be included as a priority in post-conflict reconstruction programs in order to reduce cholera outbreaks and diarrhoea related mortality.

Considerations for a WHO European strategy on health-care-associated infection, surveillance, and control

Health-care-associated infection (HAI) is a major issue of patient safety with a substantial impact on morbidity, mortality, and use of additional resources worldwide. In April 2004, the WHO Regional Office for Europe organised the first international consultation to address the issue of HAI in eastern and central Europe. The main objectives of the consultation were to identify the primary needs and obstacles for the prevention and control of HAI at country level, to design the essential components of an international strategy to effectively address the issue of HAI, and to identify specific priorities and recommendations for interventions by the WHO and other international institutions. An update on HAI activities and related networks throughout Europe, together with the outcome of the meeting, are presented, with special emphasis on future considerations for a European WHO strategy on HAI prevention.

The Verona Initiative: a new "arena" for debate on health in Europe

The Verona Initiative which aims to raise awareness of the social and ecoyzoyrzic determinants of health and advocate for new investment for health action held its first arena ("open space") meeting in Verona, Italy, on 14-17 October 1998.

[The replication of the educational activities of a course developed by the National Training Program for social health workers for controlling HIV infection]

A course for regional trainers was organized by the Working Group for HIV training (PFH) and held in Rome. This course has motivated the participants and has given them the ability to organize similar training activities at local level. The training methodology, the evaluation methods and the objectives used in the course are described. An investigation has been carried out by the Working Group of PFH to evaluate the training activity of the participants at the regional level. The results show that 17 out of the 25 participants have been able to organize a total number of 53 peripheral courses and train 2144 health workers. The training methodology and the evaluation method utilized at the different local levels have followed the ones used in the central course.

Membrane polyunsaturated fatty acids and lithium-sodium countertransport in human erythrocytes

Two groups of individuals, 26 normotensive normolipemic and 37 normotensive hyperlipemic, all without family history of hypertension have been selected in attempt to demonstrate whether Li-Na countertransport of erythrocytes is influenced by plasma and membrane lipid composition. The maximal rate of Li-Na countertransport was elevated in hyperlipemics (0.344 +/- 0.168 vs 0.220 +/- 0.074 mmol/l erythrocytes/h). This difference is highly significant. Hyperlipemics had different composition of membrane lipids than normals. The most important variations were: increase of palmitic, palmitoleic and total saturated fatty acids (SFA) as well as increase of cholesterol/phospholipids ratio (C/PL); in contrast, hyperlipemics had a reduced amount of linoleic acid and total unsaturated fatty acids (UFA) as well as total polyunsaturated fatty acids (PUFA). Consequently, UFA/SFA and PUFA/SFA ratios were lower than in normals. Li-Na countertransport was negatively correlated with the amount of PUFA (P less than 0.02), whereas it was positively correlated with the following parameters: oleic/linoleic ratio (p less than 0.02), monounsaturated fatty acids/polyunsaturated fatty acids ratio (p less than 0.03) as well as with the SFA + monounsaturated fatty acid/PUFA ratio (p less than 0.03). These findings suggest that the V max of Li-Na countertransport in erythrocytes is influenced by the lipid composition of the membrane.

Elevation of red cell sodium-lithium countertransport in hyperlipidemias

Red cell Na-Li countertransport was measured in 78 normal subjects, 64 patients with essential hypertension, and 67 patients with hyperlipidemias. Both hypertensive and hyperlipidemic patients had elevated Na-Li countertransport compared to normal controls (p less than 0.001). Subjects with hyperlipidemia and hypertension had higher countertransport (p less than 0.02) than patients with only hyperlipidemia. Normotensive hyperlipidemic subjects had higher countertransport than normotensive and normolipidemic controls (p less than 0.02). This suggest that hypertension and high plasma lipids can influence independently the Na-Li countertransport. In another group of 52 normotensive subjects, Na-Li countertransport was positively correlated with serum total and free (unesterified) cholesterol, phospholipids and triglycerides. No correlations were found with HDL-cholesterol or HDL-phospholipids. A very high positive correlation was found between Na-Li countertransport and plasma acetylcholinesterase (p less than 0.005). These findings suggest that plasma lipids, probably through membrane lipids, can affect the maximal rate of the Na-Li exchange in red cells. The relationship between plasma or membrane lipids and cation transport should be further studied in erythrocytes and other cells.
