Proceedings of the VI National Meeting of the Italian Group of Paleopathology (GIPaleo)

The presence of numerous scientific contributions in the program is certainly demonstrative of the fact that research in the field of paleopathology and anthropology has not stopped since the beginning of Covid-19. Furthermore, the same emergency that we are still partially feeling, has pushed our community scientific research to question itself more intensely in connection to the epidemic relationship and measures that repeatedly led to profound transformations in the societies of the past from different points of view: demographic, economic, social and the history buried under the bioarchaeological strata is today more capable than ever to show this connection. It can do this by bringing to light the paleodemographic data that is obtained from the study of human remains. Today we will listen to many paleopathological stories and among these I am very happy to also present ours. Twenty years ago, the University of Insubria started a collaboration with the Archaeological Superintendence of Lombardy for the study of osteological remains found mostly during emergency archaeology recoveries. These experiences led us to reach those bioarchaeological sites again with the aim of extracting all those cemetery layers that remained there because they were not subjected at that time by building reclamation interventions. Returning to those sites that in the past brought to light fragmentary anthropological data means allowing oneself the possibility of obtaining new palaeodemographic and palaeopathological data which are decisive for reconstructing the demographic and epidemiological history of the populations of the past. These new interventions led us to create an operational model that immediately intended to underline the importance of an evident continuity between the archaeological recovery and the anthropological study of the finds through the setting up of physical anthropology and paleopathology laboratories directly on the sites of the finds. All this in harmony with the final design of the projects or the museumization of bioarchaeological sites in their complexity aimed at enhancing cultural tourist routes in the area. In this regard, I would like to thank the community foundation of Varese and the Cariplo foundation for supporting our current initiatives. These include the project financed by the emblematic provincial tender and which has as its final objective the enhancement of three bioarchaeological sites in Valcuvia: the medieval sites of San Biagio in Cittiglio, Sant’Agostino in Caravate, and the modern crypt of the church of the Convent of Azzio. Today, our Research Centre works in Piedmont in different sites in the province of Vercelli and Alessandria. Aware of the importance of a physical anthropological approach in the field, our young Centre goes beyond the continental borders to reach Eritrea, the ancient city of Adulis, because it is in dissecting the taphonomic events and the funeral actions that will make it possible to identify the funerary ritual adopted by the ancient populations. The operational model of paleopathological research, which gradually enriches itself thanks to the multidisciplinary nature of the interventions and thanks to the individual experiences in the field, is thus continuously transferred and adapted to other anthropological contexts that retain potential both in terms of investigative and enhancement of the bioarchaeological heritage. Through the musealization of the sites it is also possible to acquire an attractive force towards all those potentially bioarchaeological areas but which today are in conditions of neglect because they are marginal with respect to the conventionally understood cultural tourist good. And we all know how important it is to transfer the study data even outside the academic context because making this aspect of archaeology, the truly human one, usable too, cannot fail to arouse a strong awareness of our past. We also know how much more we will have to work, following in the footsteps of the professors who started this path, to ensure that the d sciplines of paleopathology and physical anthropology arrive within all those degree courses still discovered today by these teachings to heal an important lack: knowing the human past from a physical and pathological point of view allows us to understand the evolutionary path of some pathologies, especially those of infectious nature. If my title of the speech “Paleopathology and osteoarchaeology in the province of Varese” does not respond to what is being said today, it is because my feeling about paleopathology and osteoarchaeology in the province of Varese is understood as that of carrying out research, what I could feel everywhere, through the operational model, the enthusiasm for paleopathological research and of course the people I am lucky enough to work with. The Morgagni Museum of Pathological Anatomy of the University of Padua preserves a wide series of pathological specimens, mostly from the second half of the 19th century and the early 20th century. The Museum was recently renewed, as the result of an intervention of enhancement of the museum and cultural heritage of the University of Padua and its Medical School, being also testimony to the history and evolution of human pathology and past population lifestyle. In the collection of the Morgagni Museum there are several specimens affected by atherosclerotic lesions. Atherosclerosis is characterized by a chronic inflammatory disease in which different factors are involved, such as lipoproteins, immune cells and endothelial damage. The main clinical syndromes related to atherosclerosis are angina pectoris, acute myocardial infarction, transient ischemic attack, cerebral stroke, intermittent claudication, aortic aneurysm and nephro-vascular hypertension. Atherosclerosis was believed to be a modern disease, related almost exclusively to age and current lifestyle. The cases from the Morgagni Museum are therefore useful for studying the presence of the atherosclerosis in a recent past population. In the collection there were identified six atherosclerotic cases: an atherosclerotic aneurysm of the ascending aorta: the specimen highlights the left ventricular outflow tract and the aortic root. There is a severe atherosclerosis of the ascending aorta with saccular aneurysm including a large thrombus;a syphilitic aortitis complicated by atherosclerosis: the finding highlights the left ventricular outflow tract and aortic root. It is possible to note the intima of the ascending aorta with ulcer-calcific atherosclerotic plaques and “tree-bark” whitish areas;an atherosclerotic aneurysm of the abdominal aorta: abdominal aorta with saccular atherosclerotic aneurysm, proximal to the iliac bifurcation;a case of aortic atherosclerosis: aorta with severe atherosclerosis complicated by calcification and thrombosis;a case of aortic atherosclerosis: massive dissemination of atheromatous-calcific plaques;a case of aortic atherosclerosis with parietal thrombi: widespread presence of plaques along the aortic wall. Thanks to this collection, it is possible to notice the spread of pathology on an atheromatous basis in the recent past populations. Moreover, current paleopathological investigations on ancient populations mummified remains also showed traces of atherosclerotic lesions in both sexes and different ages. It is therefore possible to support a ubiquitous diffusion in space and time of this complex multifactorial pathology which has so far considered to be almost an exclusive prerogative of old age and current lifestyle. The Morgagni Museum of Pathological Anatomy of the University of Padua, founded by Lodovico Brunetti (1813-1899) in the 1860s, gathers important pathological specimens mainly from the 19th century. Among them, there is a very peculiar preparation: it consists of a dried head representing a case of argyria dating back to 1873. The specimen is preserved in a sealed jar, all the skin has a blue-gray coloration with white-blonde hair and beard. The eyes are not preserved, but since the ocular cavities remain open, it is possible to presume that origin lly there were glass eyes. Two glass sticks are inserted inside the mouth to show that also tongue and gums have the same blue-gray pigmentation as the face. The upper teeth are strongly eroded. Argyria is a rare disease caused by chronic absorption of products with a high silver content, which surpass body’s renal and hepatic excretory capacities, leading to silver granules being deposited in the skin and its appendages, mucosae and internal organs. It is characterized by blue-gray or black staining of the skin and mucous membranes. Our case was first mentioned in 1862 as a syphilitic man who was treating himself with some caustic silver nitrate, the so called “infernal stone”, since 1840s. According to him, this medicament cured the syphilis, but turned him into a “graphite man”. The patient died in 1873 of an intestinal infection, most likely related to the prolonged ingestion of the silver nitrate. This case was described as “spectacular” by Austrian dermatologist Isidor Neumann (1832-1906), who studied a sample of the tongue of the specimen sent by Brunetti. In fact, Brunetti performed the autopsy on the body of the individual and prepared also a plaster cast of the head along with the sample for Neumann. Thus, we can assume Brunetti was also the one who preserved the original head, taxidermizing it (so-called stuffed head preparation) in order to preserve the skin color, because his famous tannisation method would not maintained the original characteristics. Human taxidermy is quite rare, and it is limited to a few cases in the 19th century. Moreover, there are just a few known human stuffed heads in the world, making the Paduan specimen particularly unique both for the pathology and the technique used for the preparation.

Features of fragile people with SARS-CoV-2 infection in isolation in a COVID-19 hotel in Rome, Italy.

OBJECTIVE: Temporary COVID-19 hotels have been established in Italy to assist the homeless people that test positive for SARS-CoV-2 and require isolation. This observational study aimed to investigate the characteristics of the subjects who were isolated at the Casa tra Noi COVID-19 hotel in Rome between October 2020 and May 2021 and to estimate the duration of SARS-CoV-2 positivity according to their main socio-demographic, behavioural and clinical features. SUBJECTS AND METHODS: Socio-demographic data, clinical history, and anamnestic data of guests were collected by the clinicians reviewing the medical documentation and face-to-face interviewing. Nasopharyngeal swabs were performed every 7 days and the presence of SARS-CoV-2 was assessed by RT-PCR. Median duration of SARS-CoV-2 positivity according to socio-demographic, behavioral factors and clinical condition was calculated. RESULTS: The 196 guests (161 males, 82.1%) had a median age of 41 years (IQR: 30-53), and were mostly African (87, 44.4%). Only asymptomatic/paucisymptomatic infections were observed. Almost half of the individuals (84, 42.9%) were affected by at least one co-morbidity, the frequency of which was higher among women (57.1% vs. 39.8%, p=0.06). The date of the negative SARS-CoV-2 molecular test was known for 144 guests (73.5%). Among these, the median duration of positivity was 21 days (IQR: 14-26) and did not significantly vary with age, country of origin, smoking status, alcohol or drug abuse. Among the co-morbidities, only infectious diseases significantly modified the duration of positivity, which increased from 21 to 34 days (p=0.013). CONCLUSIONS: Hotel guests were frequently affected by physical/mental co-morbidities. Duration of SARS-CoV-2 positivity was significantly prolonged only in individuals affected by an infectious disease.

COVID-19 detection and spread control: what initiatives in Italy for the homeless population?

In Italy COVID-19 pandemic had a severe impact. The homeless live in situations aggravating their poor health conditions and comorbidities. Although homeless people are a fragile category, no dedicated measures by public health departments seem to be applied infrequently to this population. For these reasons, they are probably one of the categories most affected by the global spread of the SARS-CoV-2. Moreover, the current vaccination campaign against COVID-19 can represent an important opportunity for health and social integration also for the homeless. This scoping review performed a map to describe strategies and interventions adopted to protect the homeless population during the COVID-19 pandemic in Italy. The methodology adheres to the PRISMA statement (extension for purpose revision) and follows the framework of Arksey and O'Malley. At the end of the selection process, 7 studies deemed relevant were included. Many strategies have been adopted to counter the spread of the virus to the homeless population, such as rapid and molecular tests with swabs or rapid blood tests. All the tests for diagnosing the infection currently in use have also been used for the homeless.

SARS-CoV-2 infection prevalence in people experiencing homelessness.

OBJECTIVE: People experiencing homelessness have peculiar characteristics that make them more vulnerable to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) transmission and to more serious forms of Coronavirus Disease 19 (COVID-19). The aim of this study was to evaluate the prevalence of SARS-CoV-2 infection in the homeless population assisted by the primary care services of the Eleemosynaria Apostolica, Vatican City. PATIENTS AND METHODS: Persons experiencing homelessness and the volunteers assisting them were tested for COVID-19 through PCR and antigen rapid test between October 1st, 2020, and June 5th, 2021, in the clinical facilities of the Eleemosynaria Apostolica. RESULTS: A total of 1665 subjects from 96 different countries in five continents were included in the study; age range was 1-90 years. Overall, 2315 COVID-19 tests through nasopharyngeal swab were performed; 1052 Polymerase Chain Reaction (PCR) tests and 1263 antigen rapid tests. Nearly 40% of the subjects underwent both tests (n=650, 39.04%), 402 were tested with PCR test only (24.14%) and 613 with antigen test only (36.8%). PCR tests were negative in 966 cases and positive in 86 (8.17%), while antigen tests were negative in 1205 cases and positive in 58 (4.59%). The number of positive cases varied over time, with a drastic increase during the winter months of 2020 and a progressive decrease over 2021. Among positive cases, 24.41% were symptomatic; symptoms included fever, breathing difficulties, anosmia/hyposmia, cough, headache, and diarrhea. CONCLUSIONS: This study reported an overall prevalence of SARS-CoV-2 infection in our sample slightly above 8%. Additional data on viral genome through sequencing of SARS-CoV-2 in positive cases are of utmost importance to help identify variants and implement specific infection control measures.

Assessment of SARS-CoV-2 infection through rapid serology testing in the homeless population in the city of Rome, Italy. Preliminary results

Background: The development of COVID-19 pandemic has affected all segments of the population;however, it had a significant impact on vulnerable subjects, such as in people experiencing homelessness. The aim of this study was to evaluate the prevalence of COVID-19 spread in homeless persons in the city of Rome, Italy. Design and Methods: Patients included in the study underwent a clinical evaluation and rapid antibody analysis on capillary blood for the presence of immunoglobulin G (IgG) and immunoglobulin M (IgM) antibodies to SARS-CoV-2 virus. Symptomatic patients were not included in the screening and immediately referred to local hospitals for further evaluation.

Homeless persons and migrants in precarious housing conditions and COVID-19 pandemic: peculiarities and prevention strategies.

Homeless persons and migrants in precarious housing conditions are vulnerable populations that have been peculiarly impacted by the Coronavirus Disease 19 (COVID-19) pandemic. These populations are more at risk of contracting COVID-19 as they often find it difficult to adhere to public health directives and, if exposed, may be more susceptible to illness or death due to the higher prevalence of underlying physical and mental comorbidities compared to the general population. In addition, vulnerable populations may have limited access to essential diagnostics and treatments, thus leading to untreated COVID-19 cases and their development into more severe forms. Health, social and government agencies should collaborate to develop services that support these communities, in accordance with the World Health Organization principles. Migrant and homeless centers have a central role, as they provide a significant contribution to prevent infection spread and favor access to early medical treatment to those affected, thus preventing more severe forms of infection.
