Use of digital technologies in public health: a narrative review.
BACKGROUND AND AIM
Websites, social media networks and mobile applications constitute important communication tools, while simultaneously enabling the population to increase their knowledge of health issues. This study aims to describe digital health experiences in Public Health to examine the different possible uses of digital technologies by Public Health Operators (PHOs) and Health Care Workers (HCWs) and the role these tools play in the efficiency of the health interventions undertaken.
METHODS
A narrative literature survey was conducted by consulting the PubMed and Scopus databases to find articles relevant to the topic of interest. The selection criteria adopted for manuscript screening involved including the survey studies dealing with the use of digital means such as new media in Public Health, published between 1 January 2012 and 31 May 2021.
RESULTS
Based on the keywords, 2,019 manuscripts were identified, of which 45 were included. The articles were grouped according to the digital tool (social media network, mobile application and websites) employed by PHOs and/or HCWs in health promotion initiatives. Specifically, this was broken down into: i) the use of social media in public health: 24 articles, ii) the use of mobile applications: 10 articles, iii) the use of websites: 8 articles and iv) the use of the three digital tools combined: 3 articles.
CONCLUSIONS
The results of this study indicate that digital technologies may play a useful role in Public Health to improve communication between health professionals and patients, provide quality care even remotely and facilitate the achievement of health outcomes for the population from a Health Literacy perspective
Organoids in Translational Oncology
Translational medicine aims to translate the most promising preclinical research into clinical practice. Oncology is a continuously growing medical field: the scientific research on cancer biology is currently based on in vitro experiments, carried out on tissue culture plates (TCPs) and other 2D samples. In this context, 3D printing has greatly improved the biofabrication of new biological matrices that mimic the extracellular environments, which may characterize healthy from cancerous tissues. Organoids have recently been described in several reports on scientific literature. The term that better describes such organoids-based tumoral tissues is "tumoroids". Tumoroids are substantially "tumor-like organoids", typically deriving from primary tumors harvested from patients. This topical review aims to give an update on organoids applied in translational medicine, paying specific attention to their use in the investigation of the main molecular mechanisms of cancer onset and growth, and on the most impacting strategies for effective targeted therapies
Diffusion and persistence of multidrug resistant salmonella typhimurium strains phage type DT120 in Southern Italy
Sixty-two multidrug resistant Salmonella enterica serovar Typhimurium strains isolated from 255 clinical strains collected in Southern Italy in 2006–2008 were characterised for antimicrobial resistance genes, pulsotype, and phage type.Most strains (83.9%) were resistant to ampicillin, chloramphenicol, streptomycin, sulfamethoxazole, and tetracycline (resistance pattern ACSSuT) encoded in 88.5% by the PSE-1, floR, aadA2, sul1, and tet(G) gene cluster harboured by the Salmonella Genomic Island (SGI1). In 11.5% of strains, the resistance was encoded by the InH-like integron (OXA-30-aadA1) and the catA1, sul1, and tet(B) genes. STYMXB.0061 (75%) and DT120 (84.6%) were the prevalent pulsotype and phage type identified in these strains, respectively. Five other resistance patterns were also found either in single or in a low number of isolates with TEM, dfrA12, strAB, sul2, tet(A), and tet(B) encoding for the associated ampicillin, trimethoprim, streptomycin, sulfamethoxazole, and tetracycline resistances, respectively. The pandemic DT104 clone, resistance pattern ACSSuT encoded by SGI1, has largely been identified in Italy since 1992, while strains DT120, resistance pattern ACSSuT (encoded by SGI1), have never been previously reported in Italy. In Europe, clinical S. Typhimurium strains DT120 have mainly been reported from sporadic outbreaks linked to the consumption of pork products.However, none of these strains were STYMXB.0061 and the antimicrobial resistance was not linked to SGI1.Theprevalent identification and persistence ofDT120 isolates would suggest, in Southern Italy, a phage type shifting of the pandemic DT104 clone pulsotype STYMXB.0061.Additionally, these findings raise epidemiological concern about the potential diffusion of these emerging multidrug resistant (SGI linked) DT120 strains
A Dedifferentiation Strategy to Enhance the Osteogenic Potential of Dental Derived Stem Cells
Dental stem cells (DSCs) holds the ability to differentiate into numerous cell types. This property makes these cells particularly appropriate for therapeutic use in regenerative medicine. We report evidence that when DSCs undergo osteogenic differentiation, the osteoblast-like cells can be reverted back to a stem-like state and then further differentiated toward the osteogenic phenotype again, without gene manipulation. We have investigated two different MSCs types, both from dental tissues: dental follicle progenitor stem cells (DFPCs) and dental pulp stem cells (DPSCs). After osteogenic differentiation, both DFPCs and DPSCs can be reverted to a naĂŻve stem cell-like status; importantly, dedifferentiated DSCs showed a greater potential to further differentiate toward the osteogenic phenotype. Our report aims to demonstrate for the first time that it is possible, under physiological conditions, to control the dedifferentiation of DSCs and that the rerouting of cell fate could potentially be used to enhance their osteogenic therapeutic potential. Significantly, this study first validates the use of dedifferentiated DSCs as an alternative source for bone tissue engineering
Efficacy of Sea Salt-Based Mouthwash and Xylitol in Improving Oral Hygiene among Adolescent Population: A Pilot Study
The scientific community has definitely demonstrated the importance of the use of mouthwash in daily oral hygiene. In our pilot study, we tested the effectiveness of a novel mouth rinse containing sea salt, xylitol, and lysozyme. Streptococcus mutans (S. mutans) growth, and plaque index in adolescent patients aged 14–17 years, were observed. The bacterial load was investigated by in vitro microbiological analysis; the plaque index was assessed through the O’Leary’s Plaque Control Record (PCR). The study has shown that the use of a sea salt-based mouthwash in daily oral hygiene reduces the bacterial levels of S. mutans (p < 0.01) linked to the combined action of xylitol and lysozyme, together with the action of sea salt. Our preliminary data confirm and improve the main results reported in the scientific literature on the importance of the use of xylitol, lysozyme, and sea salt in oral health
Cutaneous manifestations of Mycobacterium gordonae infection described for the first time in Italy: a case report
Introduction: Mycobacterium gordonae is one of the least pathogenic of the mycobacteria. This
pathogen may produce caseating or non-caseating granulomas, and skin lesions showing acute or
chronic inflammation with scattered histiocytes and giant cells have been seen. The mortality rate is
less than 0.1%. Mycobacterium gordonae may be a marker of severe immunosuppression in patients
infected with human immunodeficiency virus.
Case presentation: We report a case of Mycobacterium gordonae infection in an 86-year-old woman
and discuss the problems inherent to the identification and treatment of this emerging pathogen.
Mycobacterium gordonae strain we isolated was resistant to trimethoprim-sulfamethoxazole but
sensitive to ciprofloxacin, and long term administration (six months) induced complete healing of the
cutaneous abscesses.
Conclusion: Advanced laboratory diagnostic techniques have improved the isolation and
identification of nontuberculous mycobacteria. The diagnosis requires a high index of clinical
suspicion, as detection by conventional methods is difficult. To our knowledge, this patient is the first
documented case of cutaneous infection from this pathogen in Italy
Probiotics in Health and Immunity: A First Step toward Understanding the Importance of Microbiota System in Translational Medicine
There are mounting evidences showing the relation of chronic inflammatory and autoimmune diseases with the uncontrolled intensification of gut dysbiosis. This position asserts that an elevated presence of pathogens and bacterial, fungal, and viral components is directly involved in inflammatory metabolic diseases with a strong alteration of autoimmune components such as in inflammatory bowel syndrome (IBS), ulcerative colitis, and Crohn’s disease. Furthermore, the increase of unbalanced enteric microbiota is also connected to other types of conditions of metabolic origin such as diabetes mellitus, atherosclerosis, and osteo-degenerative conditions. As a matter of fact, evidence confirmed that gut damages histologically inspected revealed a situation with high expression of pro-inflammatory cytotumor necrosis factor-alpha (TNF-α), and IL1β, IL-2, IL-4, IL-6, and IL-17 together with high level of mucin-2. This chapter focuses on diverse topics related to microbiota dysfunction and systemic health condition and regenerative capacity and the therapeutic role of probiotics in gut health and disease emphasizing the potential beneficial role of probiotics in idiopathic inflammatory metabolic diseases. In brief, outcomes demonstrate that an intimate relationship between microbiota, metabolism, tissue/cellular damages, and regeneration is standing. Within this scenario, the gut certainly plays a big part of the regenerative mechanisms in translational medicine
Probiotics Improve Urogenital Health in Women
BACKGROUND: Urogenital recurrent infections represent a global medical issue in the world, affecting millions of women because of dramatic shifts in bacterial composition and concentrations in response to numerous endogenous and exogenous factors. Urogenital microbiota forms a mutually beneficial relationship with their host and has a major impact on health and disease.
AIM: This study aimed to compare probiotic therapy versus placebo in Oxidative Stress Values (OSVs) and histological features in urogenital infections in female patients.
METHODS: Forty (n = 40) patients diagnosed with recurrent urogenital infections were recruited to be treated as test group (n = 20), receiving Probiotics, and a control group (n = 20), receiving looking similar placebo, both for 90 days. Both the groups were assessed for total oxidant capacity (d-ROMs test) and biological antioxidant potential as iron-reducing activity (BAP test) at baseline, after 1 and 3 months. Histological changes on inner vaginal mucosa were also investigated, during the entire study.
RESULTS: d-ROM assay clearly showed that the values of the test group were significantly different, thus leading the general health conditions from a state of high oxidative stress to low oxidative stress levels. Increasing of BAP values were more significant, and clinically relevant, in probiotic test group over time.
CONCLUSION: Our pilot study gave interesting and promising elements to confirm the safety and effectiveness of oral probiotics in preventing/reducing the recurrent urogenital infections by an overall modification of inner vaginal microbiota
Serological Profile of Children and Young Adults with at Least One SARS-CoV-2 Positive Cohabitant: An Observational Study
At the end of 2019, a new disease caused by the novel coronavirus SARS-CoV-2 appeared
in Wuhan Province in China. Children seemed to be infected less frequently than adults, and family
clusters seemed to play an important role in the spread of the pandemic. The aim of this study is to
evaluate the serological profile of children and young adults between 4 and 16 years of age in order
to assess the transmission patterns of COVID-19 between cohabitants. The subjects lived with at
least one cohabitant who tested positive for the disease using a nasopharyngeal swab. To avoid
contact with the disease, families were interviewed by telephone. Forty-nine children and
adolescents with a mean age of 11 years were then subjected to a rapid lateral flow chromatographic
test. Of them, seven (14.3%) were immunoglobulin G (IgG)-positive, and four (8.2%) were
immunoglobulin M (IgM)-positive. In total, 16.3% of the tested sample had antibodies against
SARS-CoV-2: this may confirm the lower vulnerability of children to COVID-19, despite the small
sample size. The time from the negativization of the cohabitant until the test day may have
influenced the results, especially when this timeframe is wide
Chronic periodontitis and immunity, towards the implementation of a personalized medicine: A translational research on gene single nucleotide polymorphisms (SNPs) linked to chronic oral dysbiosis in 96 caucasian patients
Chronic periodontitis (CP) is a complex pathology with a significant impact worldwide causing bone loss. Oral dysbiosis is a highly inflammatory condition associated to a long-term insulting infection and represents an underestimated CP key factor associated with an imbalance of pro-inflammatory and anti-inflammatory gene responses. The presence of a single nucleotide polymorphisms (SNPs) in the promoter region of interleukin 10 (IL-10) gene-1082,-819, and-592 was a possible determinant cause. This translational research aimed to provide outcomes on the role of IL-10 gene expression in bone loss diseases in patients affected by CP. Caucasian patients (n = 96) affected by CP were recruited from the Italian population. The subgingival samples were collected using the Bacterial Periodontal Assessment by Biomolecular Diagnostic® and the characterization of a set of 15 bacterial DNA responsible of periodontitis was performed by real-time multiplex PCR. In addition, two viruses, Epstein-Barr Virus (EBV) and Herpes Simplex Virus 1 (HSV-1), and a pathogenic fungi (Candida albicans) were included as a part of our panel. Our results confirmed an existing association between IL-10 gene polymorphisms and polymorphism of tumor necrosis factor alpha (TNFff), interleukin 1α-β-RN (IL-1α-β-RN), collagen type-l alpha (COLIA1), and vitamin D receptor (VDRs) genes in CP. Further studies are needed to improve diagnosis and endorse more effective therapeutic procedures for periodontal disease
