These studies spanned the period from 1994 to 2023 and were conducted in Brazil, Peru, Cuba, Colombia, Trinidad and Tobago, Mexico, and Chile. The mean prevalence of LTBI among HCWs was 35.32% (range 17.86-56.00%) for interferon-gamma release assay (IGRA) and 43.67% (range 6.68-70.29%) for tuberculin skin test (TST). The pooled prevalence of LTBI among HCWs was 34.5% (95% CI 25.4-44.1%) for IGRA and 43.0% (95% CI 35.5-50.7%) for TST. When considering both IGRA and TST tests, the overall prevalence of LTBI among HCWs was 40.98% (95% CI 34.77-47.33%). LTBI was associated with longer lengths of employment and exposure to patients, family members, or any person with TB. Additionally, older HCWs faced a higher risk of LTBI. Specific professional roles (such as nurses, nurse technicians, or physicians), smoking, and deficient TB infection control measures increased the likelihood of LTBI.

CDI's (<i>Clostridioides difficile</i> infection) impact on healthcare systems is concerning due to high treatment cost and increased hospitalisation time. The incidence of CDI has been influenced by hypervirulent strains such as the 027 ribotype, responsible for significant outbreaks in North America and Europe. CDI's epidemiology has evolved, showing increased community-acquired cases alongside traditional hospital-acquired infections. Mortality rates remain high, with recurrent infections further elevating the risk. Transmission of <i>C. difficile</i> primarily occurs via spores, which survive in healthcare settings and play a pivotal role in transmission. Not only health workers, but also the food chain could have a significant impact on the transmission of infection, although no confirmed foodborne cases have been documented. Pathogenicity of <i>C. difficile</i> involves spore germination and toxin production. Toxins A and B can cause cellular damage and inflammatory responses in the host, leading to colitis. Clinical picture can range from mild diarrhea to fulminant colitis with toxic megacolon, and bowel perforation. Risk factors for CDI include antibiotic exposure, advanced age, hospitalization, and use of proton pump inhibitors. Patients who experience abdominal surgery or patients with inflammatory bowel disease (IBD) are particularly susceptible due to their compromised gut microbiota. Management of CDI has evolved, with fidaxomicin emerging as a superior treatment option over vancomycin for initial and recurrent infections due to its reduction of recurrence rate. Faecal microbiota transplantation (FMT) is effective for recurrent CDI, restoring gut eubiosis. Bezlotoxumab, a monoclonal antibody against <i>C. difficile</i> toxin B, has shown promise in reducing recurrence rates. Severe cases of CDI may require surgical intervention, particularly in instances of toxic megacolon or bowel perforation. In conclusion, CDI remains a significant clinical entity.

Unfortunately, those living in endemic regions, especially survivors, are often confronted with the harsh reality of reduced quality of life as measured by disability-adjusted life years. Meningitis is one of the leading causes of mortality and morbidity, especially in the meningitis belt of sub-Saharan Africa, with a recorded disease burden of over 2.5 million cases globally and children under five disproportionately impacted. This paper examines the global burden of meningitis, exploring its prevalence and impact across different regions. It further analyzes the evolution of vaccination strategies for meningitis prevention, emphasizing the recent development and introduction of the novel Men5CV meningococcal conjugate vaccine. Recurrent meningitis outbreaks across the meningitis belt have resulted in significant mortality over decades. A major turning point in the fight against the serogroup A epidemic was the development of the MenAfriVac vaccine, which resulted in declining cases. However, serogroups C, W, and X continue to pose problems. The novel pentavalent (Men5CV) vaccine has emerged as a remarkable advancement in the fight against meningitis, with its safety and effectiveness against a variety of serogroups, including the elusive serogroup X, demonstrated in clinical trials. Its pre-qualification by the World Health Organization (WHO), and subsequent recommendation for incorporation into routine immunization programs issued a new era with the potential for meningitis eradication. Nigeria now sets a benchmark for other nations in the meningitis zone, becoming the first country in the world to roll out the new Men5CV vaccines. Funding from organizations like Gavi, the Vaccine Alliance, highlights the importance of coordinated international efforts aligned with the WHO's roadmap for meningitis elimination by 2030. Stakeholder involvement, extensive immunization campaigns, and a strong healthcare infrastructure are all practical recommendations for public health integration.</p>","PeriodicalId":502111,"journal":{"name":"Le infezioni in medicina","volume":"32 3","pages":"323-329"},"PeriodicalIF":0.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11392544/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142305650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
