The Risk of COVID-19 Infection in Prisons and Prevention Strategies: A Systematic Review and a New Strategic Protocol of Prevention

Health risks within prisons are well known and have worsened with the 2019 coronavirus pandemic (COVID-19), becoming a public health emergency. To date, there are more than 10 million inmates in the world; in most cases, conditions are bad and health care is scarce. A SARS-CoV-2 outbreak inside a prison is extremely rapid. The aim of this systematic review was to analyze all possible prevention techniques to reduce the risk of COVID-19 related infection within prisons. A systematic review of the literature was performed according to the PRISMA guidelines. Scopus, Web of Science, PubMed, and Google Scholar were used as search engines from 1 January 2020 to 1 November 2021 to evaluate the prevention of COVID-19 in prisoners. A total of 1757 articles were collected. Of them, 486 duplicates were removed. A total of 1250 articles did not meet the inclusion criteria. In conclusion, 21 articles were included in the present systematic review. From this analysis, it emerged that the most common COVID-19 prevention methods were the screening of the entire population (prisoners and workers) inside the prison through swab analysis and the reduction in overcrowding in prisons. Few studies concerned the prevention of COVID-19 infection through vaccination and the implementation of quarantine. To our knowledge, this is the first systematic review that evaluates the prevention of COVID-19 within jails and the real effectiveness of all possible methods used and published in the literature. Finally, a very useful strategic protocol is provided to reduce the incidence of infection and to control and manage COVID-19 in prisons.

Forensic Post-Mortem Investigation in AAS Abusers: Investigative Diagnostic Protocol. A Systematic Review

Anabolic–androgenic steroids (AASs) are a group of synthetic molecules derived from testosterone and its precursors. AASs are widely used illicitly by adolescents and athletes, especially by bodybuilders; AASs are among the most used drugs for improving physical performance, as well as for aesthetic purposes. The use of AASs by professional and recreational athletes is increasing worldwide. This review focused on deaths related to AAS abuse and to investigation of the autopsy results and histopathological findings using a rigorous methodology protocol covering: a complete autopsy, histological analysis, and a broad toxicological investigation. Moreover, we aimed to define an investigative diagnostic protocol supporting forensic pathologists during the post-mortem investigation of AAS abusers. This review was conducted using PubMed Central and Google Scholar databases to find articles published between 1 January 1968 and 30 June 2021, using the following key terms: “(anabolic-androgenic steroids) AND (autopsy); (anabolic-androgenic steroids) AND (forensic)”. A total of 939 articles were screened and 926 did not meet the inclusion criteria. In conclusion, 14 articles were included in this systematic review, reporting 137 fatal cases of AAS abuse in total. The histopathologic studies showed myocardial damage characterized by myocyte hypertrophy, focal myocyte damage with myofibrillar loss, interstitial fibrosis, mostly subepicardial, and small vessel disease. Indeed, in AAS-related cases, autopsy plays a pivotal role in the study of AAS adverse effects and organ damage related to their use or abuse. This systematic review aimed to define a specific workflow in death cases related to AASs, suggesting important future insights to better clarify sudden deaths related to AASs, such as the use of miRNAs. The forensic community needs a unified approach in cases of suspected death related to the use of AASs. There are several occasions to apply this workflow, for example in cases of death of bodybuilders and of young people who die in gymnasiums or during sports activities.

Novel diagnostic approaches to intrauterine neoplasm in fertile age: sonography and hysteroscopy

Endometrial carcinoma (EC) is the most common gynecological malignancy in the world. It is mostly detected in postmenopausal women, but it can also occur in women of fertile age who need fertility-sparing therapy. An early diagnosis is the main objective for the correct management of these patients, making it possible to use a fertility-sparing treatment approach without exposing the patients to the risk of cancer progression. In this review, we discuss the role of sonography and hysteroscopy in the detection of intrauterine neoplasm in women of childbearing age.

Safe Management Strategies in Clinical Forensic Autopsies of Confirmed COVID-19 Cases

To date, there is poor evidence on the transmission of infection in individuals handling the bodies of deceased persons infected with SARS-CoV-2 and in particular, during autopsies. The aim of this study was to demonstrate that when appropriate strategies are adopted autopsy is a safe procedure with a minimal infection risk for all subjects involved (pathologists, technical personnel, and others) when proper strategies are adopted. We performed 16 autopsies on cadavers of persons who had died with confirmed COVID-19 with different post-mortem intervals (PMI). To confirm the presence of SARS-CoV-2 RNA, for each autopsy, 2 swabs were sampled from lungs, while to evaluate environmental contamination, 11 swabs were taken at three different times: T0 (before autopsy), T1 (at the end of the autopsy, without removing the corpse), and T2 (after cleaning and disinfecting the autopsy room). Specifically, 2 swabs were sampled on face shields used by each pathologist, and 4 swabs were collected on the autopsy table; 4 swabs were also collected from walls and 1 from floor. Lung swabs confirmed the presence of SARS-CoV-2 RNA in all cases. Environmental swabs, collected at T0 and T2 were all negative, while swabs sampled at T1 were shown to be positive. Interestingly, no association was shown between PMI length and environmental contamination. Infection control strategies for safe management of clinical forensic autopsies of bodies with suspected or confirmed COVID-19 are also described.

Neurological Sequelae in Patients with COVID-19: A Histopathological Perspective

BACKGROUND

Neuroinvasive properties of SARS-CoV-2 have allowed the hypothesis of several pathogenic mechanisms related to acute and chronic neurological sequelae. However, neuropathological correlates have been poorly systematically investigated, being retrieved from reports of single case or limited case series still.

METHODS

A PubMed search was carried out to review all publications on autopsy in subjects with "COronaVIrus Disease-19" (COVID-19). Among them, we focused on histological findings of the brain, which were compared with those from the authors' autoptic studies performed in some COVID-19 patients.

RESULTS

Only seven studies reported histological evidence of brain pathology in patients deceased for COVID-19, including three with reverse transcription-quantitative polymerase chain reaction evidence of viral infection. All these studies, in line with our experience, showed vascular-related and infection-related secondary inflammatory tissue damage due to an abnormal immune response. It is still unclear, however, whether these findings are the effect of a direct viral pathology or rather reflect a non-specific consequence of cardiovascular and pulmonary disease on the brain.

CONCLUSIONS

Notwithstanding the limited evidence available and the heterogeneity of the studies, we provide a preliminary description of the relationship between SARS-CoV-2 and brain sequelae. Systematic autoptic investigations are needed for accurate detection and adequate management of these patients.

Anaphylactic Death: A New Forensic Workflow for Diagnosis

Anaphylaxis is a life-threatening or fatal clinical emergency characterized by rapid onset, and death may be sudden. The margin of certainty about the diagnosis of anaphylactic death is not well established. The application of immunohistochemical techniques combined with the evaluation of blood tryptase concentrations opened up a new field of investigation into anaphylactic death. The present study investigated eleven autopsy cases of anaphylactic death, carried out between 2005 and 2017, by the Departments of Forensic Pathology of the Universities of Foggia and Catania (Italy). An analysis of the medical records was carried out in all autopsies. Seven autopsies were carried out on males and four on females. Of the eleven cases, one showed a history of asthma, one of food ingestion, two of oral administration of medications, six did not refer any allergy history, and one subject was unknown. All cases (100%) showed pulmonary congestion and edema; 7/11 (64%) of the cases had pharyngeal/laryngeal edema and mucus plugging in the airway; only one case (9%) had a skin reaction that was found during external examination. Serum tryptase concentration was measured in ten cases, and the mean value was 133.5 µg/L ± 177.9. The immunohistochemical examination using an anti-tryptase antibody on samples from the lungs, pharynx/larynx, and skin site of medication injection showed that all cases (100%) were strongly immunopositive for anti-tryptase antibody staining on lung samples; three cases (30%) were strongly immunopositive for anti-tryptase antibody staining on pharyngeal/laryngeal samples; and eight cases (80%) were strongly immunopositive for anti-tryptase antibody staining on skin samples. We conclude that a typical clinical history, blood tryptase level >40 µg/L, and strongly positive anti-tryptase antibody staining in the immunohistochemical investigation may represent reliable parameters in the determination of anaphylactic death with the accuracy needed for forensic purposes.

Sudden Cardiac Death in Anabolic-Androgenic Steroid Users: A Literature Review

Background and objectives: Anabolic-androgenic steroids (AASs) are a group of synthetic molecules derived from testosterone and its related precursors. AASs are widely used illicitly by adolescents and athletes, especially by bodybuilders, both for aesthetic uses and as performance enhancers to increase muscle growth and lean body mass. When used illicitly they can damage health and cause disorders affecting several functions. Sudden cardiac death (SCD) is the most common medical cause of death in athletes. SCD in athletes has also been associated with the use of performance-enhancing drugs. This review aimed to focus on deaths related to AAS abuse to investigate the cardiac pathophysiological mechanism that underlies this type of death, which still needs to be fully investigated. Materials and Methods: This review was conducted using PubMed Central and Google Scholar databases, until 21 July 2020, using the following key terms: “((Sudden cardiac death) OR (Sudden death)) AND ((androgenic anabolic steroid) OR (androgenic anabolic steroids) OR (anabolic-androgenic steroids) OR (anabolic-androgenic steroid))”. Thirteen articles met the inclusion and exclusion criteria, for a total of 33 reported cases. Results: Of the 33 cases, 31 (93.9%) were males while only 2 (61%) were females. Mean age was 29.79 and, among sportsmen, the most represented sports activity was bodybuilding. In all cases there was a history of AAS abuse or a physical phenotype suggesting AAS use; the total usage period was unspecified in most cases. In 24 cases the results of the toxicological analysis were reported. The most detected AASs were nandrolone, testosterone, and stanozolol. The most frequently reported macroscopic alterations were cardiomegaly and left ventricular hypertrophy, while the histological alterations were foci of fibrosis and necrosis of the myocardial tissue. Conclusions: Four principal mechanisms responsible for SCD have been proposed in AAS abusers: the atherogenic model, the thrombosis model, the model of vasospasm induced by the release of nitric oxide, and the direct myocardial injury model. Hypertrophy, fibrosis, and necrosis represent a substrate for arrhythmias, especially when combined with exercise. Indeed, AAS use has been shown to change physiological cardiac remodeling of athletes to pathophysiological cardiac hypertrophy with an increased risk of life-threatening arrhythmias.

Catheter-related Bloodstream Infections: A Root Cause Analysis in a Series of Simultaneous Ochrobactrum anthropi Infections

Objective:

Catheter-related bloodstream infections (CRBSIs) pathogenesis is complex and multifactorial mostly due to cutaneous microorganisms migration through the catheter insertion site and catheter tip colonization. Ochrobactrum anthropi is a gram-negative bacterium belonging to the Brucellaceae and related infections are especially observed in immunocompromised patients.

Methods:

Therefore, O. anthropi infection prevention and surveillance are relevant issues for healthcare system and risk management, in order to improve healthcare quality and patient safety. Four cases of anthropi-related CRBSIs occurring in immunodepressed patients under chemotherapy treatment are reported and the possible prevention and surveillance strategies are analyzed.

Results:

In the reported cases, all infections occurred almost simultaneously in the Oncology Unit, leading to hypothesize an identical infection source. Subsequently, a clinical audit was performed in order to investigate infection origin and implement prevention and control strategies. Clinical audit allowed to identify the hand hygiene defects as the primary source of the infections, responsible for catheter flushing solution contamination.

Conclusion:

The aim of this study is to reveal how through correct root cause analysis and clinical audit, several measures could be undertaken in order to promote the prevention of the CRBSIs risk

The therapeutic use of cannabinoids: Forensic aspects

Since 2013 in the Italian market has been introduced the Nabiximols, a drug containing two of the main active cannabinoids: Δ(9)-tetrahydrocannabinol (Δ(9)-THC) and cannabidiol (CBD). This drug has been approved in Italy in the treatment of Multiple Sclerosis (MS). It is an oral spray formulation and each puff of 100μl contains 2.7mg of Δ(9)-THC and 2.5mg of CBD. In the present study we analyzed urine and blood samples collected from a group of 20 patients treated with Nabiximols in order to evaluate: blood Δ(9)-THC concentrations in relation to the dose administered and the duration of treatment and the potentiality of this medication to be used for drug habit.

METHODS

The study was conducted on a sample group of patients affected by MS, of both sexes, age: 49-61 years, treated with Nabiximols for short (28 days) or long-term. The results of our study allow affirming that it is unlikely to use this medication for drug habit or to sale it in the black market because of the low blood concentrations available and of its high costs. These statements were confirmed by: (a) the low Δ(9)-THC concentrations in the pharmaceutical formulation; (b) the low blood concentrations produced by Nabiximols administration, more than 10 times smaller than the blood concentrations known to produce psychotropic effects; (c) the presence of CBD (Δ(9)-THC natural antagonist); (d) the route of administration (inhaled, not smoked).

Headache and Multiple Sclerosis: A Population-Based Case-Control Study in Catania, Sicily

We carried out a population-based case-control study to evaluate the association between multiple sclerosis (MS) and headache. We had previously determined the incidence of MS during 1990-1999 in Catania, Sicily, identifying 155 incident MS patients; these subjects underwent a telephone interview using a standardized questionnaire for headache. Diagnosis and classification of headaches were made according to International Headache Society criteria (1988). A control group was selected from the general population through random digit dialling. One hundred and one (65.2±) MS patients, of the 155 identified, and 101 controls were screened for headaches. Fifty-eight (57.4±) MS patients and 38 (37.2±) controls fulfilled the diagnostic criteria of headache. A significant association between MS and headache was found with an adjusted odds ratio, estimated by logistic regression, of 2.18 (95± confidence interval 1.27, 3.93). Frequency of headaches in our MS population is higher than in the general population, supporting the hypothesis of a possible association between these two conditions.

Frequency of celiac disease is not increased among multiple sclerosis patients

We evaluated the presence of IgA and IgG celiac disease-related antibodies in a sample of 217 patients with multiple sclerosis (MS) and in a sample of 200 controls not affected by neurological disorders. None of the 217 patients with MS presented IgG and IgA anti-gliadin, anti-endomysial antibodies, anti-tissue transglutaminase and anti-reticulin, whereas only one of the selected controls presented specific antibodies; this subject resulted to be effectively affected by celiac disease. Our data did not show an increased frequency of celiac disease among patients with MS.

[Prognostic factors in functional outcome after stroke: a review]

Survivors of stroke constitute the largest group of patients receiving rehabilitative therapy. Purpose of this article is to review the prognostic factors which can affect functional outcome after stroke. An accurate prognostic assessment is fundamental after cerebrovascular accident, in order to plan the rehabilitative project and define both early and long-term objectives. We found agreement of opinions about the prognostic value of some factors, whereas three are difference of opinions about other prognostic factors in predicting neurological outcome.

[Neuroprotective effects of topiramate]

Topiramate (TPM) is a new anti-convulsant drug, prescribed in epileptic seizure. Pharmacological actions of TPM are: a) a positive modulation of GABA receptors; b) inhibition of the kainite and aminohydroxymethylisoxazole propionic acid (AMPA) glutamate receptor sub-types; c) a use-dependent Na+ channel blocker. Recent studies suggest that TPM can have anti-excitotoxic properties, because it protects against motor neuron degeneration. Moreover, TPM enhances neuroprotection and reduces hemorrhagic incidence in focal cerebral ischemia.

[Neurogenic dysphagia: physiology, physiopathology and rehabilitative treatment]

Swallowing is both a voluntary than a reflex function. It consist in transporting feeding from mouth to the stomach. Swallowing function occurs with very frequency during the day and needs complex neuromuscular coordination. Several neurologic diseases determine swallowing disorders. Dysphagia, is the difficulty in swallowing. In slight disorders, swallowing function is sufficiently compensated, symptoms are few or absent. Sometimes the patient is able to compensate and obtains a safe deglutition. Rehabilitation of swallowing disorders is based on the assessment of all symptoms and troubles causing dysphagia and on the improvement of the specific disabilities. Rehabilitation is aimed to make patient able for a safe oral feeding. We can use classic specific physiotherapy, compensatory movements of head and neck, electrostimulation, and the chemical myotomia by botulinum toxin injection.
