COVID-19-associated pulmonary aspergillosis in intensive care unit: A real-life experience.

Since 2020, cases of COVID-19-associated pulmonary aspergillosis (CAPA) have been frequently described, representing an important cause of mortality, especially among patients admitted to intensive care unit (ICU). A predisposition to invasive infection caused by Aspergillus spp. in SARS-CoV-2 infected patients can be ascribed either to the direct viral-mediated damage of the respiratory epithelium or to the dysregulated immunity associated with COVID-19. In this case series we have collected the clinical, laboratory and radiological data of 10 patients admitted to the ICU with diagnosis of probable CAPA, according to the recent expert consensus statement, from March 2020 to December 2022 in the Teaching Hospital of Catanzaro in Italy. Overall, 249 patients were admitted to the COVID-19-ICU from March 2020 to December 2022; out of these, 4% developed a probable CAPA. Most of patients were male with a mean age of 62 years. Only two patients had an underlying immunocompromising condition. The observed mortality was 70%. In our institution, all COVID-19 patients requiring invasive mechanical ventilation systematically underwent bronchoscopy with bronchoalveolar lavage for an early evaluation of bacterial and/or fungal co- or super-infections, including galactomannan test. Patients were re-evaluated by an infectious diseases consultant team every 24-48 hours and the galactomannan test was systematically repeated based on patient's clinical course. Even though the numbers in this study are very small, we report our experience about the role of early diagnosis and careful choice of antifungal therapy, considering the fragility of these patients, and its relationship with outcomes. Despite a systemic approach allowing early diagnosis and initiation of anti-fungal therapy, the mortality rate turned out to be very high (70%).

New advances in management and treatment of cardiac implantable electronic devices infections.

Cardiac implantable electronic devices (CIED) are increasingly used worldwide, and infection of these devices remains one of the most feared complications.CIED infections (CDIs) represent a challenge for physicians and the healthcare system in general as they require prolonged hospitalization and antibiotic treatment and are burdened by high mortality and high costs, so management of CDIs must be multidisciplinary.The exact incidence of CDIs is difficult to define, considering that it is influenced by various factors mainly represented by the implanted device and the type of procedure. Risk factors for CDIs could be divided into three categories: device related, patient related, and procedural related and the etiology is mainly sustained by Gram-positive bacteria; however, other etiologies cannot be underestimated. As a matter of fact, the two cornerstones in the treatment of these infections are device removal and antimicrobial treatment. Finally, therapeutic drug monitoring and PK/PD correlations should be encouraged in all patients with CDIs receiving antibiotic therapy and may result in a better clinical outcome and a reduction in antibiotic resistance and economic costs.In this narrative review, we look at what is new in the management of these difficult-to-treat infections.

From the Global North to the Global South: preparing students for away rotations.

Makerere University College of Health Sciences, Kampala, Uganda, has established partnerships with several other institutions worldwide, including the University of Brescia and "Magna Græcia" University, which have agreed to collaborate for the primary purpose of student exchange. Our aim is to comment on students' preparation for away rotations based on the authors' own experiences and opinions alongside a review of selected papers on the preparation of students for global health and ethical collaboration. Medical electives represent a unique opportunity for all medical students, not merely for those who will work in resource-limited settings due to increasing globalization. The emergence of ethical international collaborations is of paramount importance to stimulate these projects and ensure that they are implemented safely and with adequate preparation even and especially during the COVID-19 pandemic.

Microbiological and Clinical Findings of SARS-CoV-2 Infection after 2 Years of Pandemic: From Lung to Gut Microbiota.

Early recognition and prompt management are crucial for improving survival in COVID-19 patients, and after 2 years of the pandemic, many efforts have been made to obtain an early diagnosis. A key factor is the use of fast microbiological techniques, considering also that COVID-19 patients may show no peculiar signs and symptoms that may differentiate COVID-19 from other infective or non-infective diseases. These techniques were developed to promptly identify SARS-CoV-2 infection and to prevent viral spread and transmission. However, recent data about clinical, radiological and laboratory features of COVID-19 at time of hospitalization could help physicians in early suspicion of SARS-CoV-2 infection and distinguishing it from other etiologies. The knowledge of clinical features and microbiological techniques will be crucial in the next years when the endemic circulation of SARS-CoV-2 will be probably associated with clusters of infection. In this review we provide a state of the art about new advances in microbiological and clinical findings of SARS-CoV-2 infection in hospitalized patients with a focus on pulmonary and extrapulmonary characteristics, including the role of gut microbiota.

Evidence of Low Prevalence of Cystic Echinococcosis in the Catanzaro Province, Calabria Region, Italy.

Cystic echinococcosis (CE) is one of the neglected tropical diseases recognized by the WHO. Echinococcus granulosus sensu lato affects more than 1 million people worldwide and is responsible for high costs in the healthcare system. A clear knowledge of the prevalence of CE and its clinical characteristics could have an important impact on the approach to its diagnosis and to the public health planning of treatment and control interventions. We performed a prevalence study in four municipalities of Catanzaro Province, South Italy. This area is considered to be at high risk of CE because of ovine breeding. We screened by abdominal ultrasound 2,426 volunteers, four of whom had abdominal CE. Given the need for prevention and control programs for CE in endemic areas of Italy, a detailed mapping of prevalence of CE, to complement data obtained through hospital discharge records, appears imperative.

Risk factors for hepatitis B and C among healthy population: a community-based survey from four districts of Southern Italy.

In Southern Italy, viral hepatitis B and C still represent an important public health problem, with a serious social impact, and significant economic consequences. The objective of our community-based study was to assess the prevalence of risk factors and access to the test for viral hepatitis to get information for guiding prevention and screening strategies in our setting. The study was conducted among population of four selected districts in Southern Italy during May 2019. An anonymous structured questionnaire consisting of multiple-choice questions was administered by trained research assistants in order to assess any possible risk factor for HCV or HBV acquisition, and if any screening was previously performed. Six-hundred participants were included: 367 (61.2%) were females, with a mean age of 51 years (standard deviation, SD: 18 years). The three most frequent risk factors were: dental treatments in 425/600=70.8% (of whom 76/425=17.8% were previously tested), unprotected sexual intercourses in 340/600=56.6% (of whom 54/340=15.8% were previously tested), and injections with glass syringes in 162/600=27% (of whom 32/162=19.7% were previously tested). Only 47/502 (9.3%) patients who were never been tested, did not report any risk factors for HCV or HBV acquisition, while 433 (86.2%) reported at least one risk factor, 293 (58.3%) at least two, 97 (19.3%) at least three, 16 (3.1%) at least four, and 2 reported to have at least five risk factors for HBV/HCV acquisition.
