Abstract
Background: Healthcare workers (HCWs) are considered at higher risk for hepatitis B virus infection compared to the general population, due to their potential contact with blood or body fluids and possible needle stick injuries. In turn, infected HCWs may be a risk for patients. Hepatitis B vaccination programs represent a strategic approach to control the infection. Objectives: In this study, we aimed to evaluate the serological status of HCWs employed at the teaching hospital of Rome Tor Vergata and their risk of occupational injuries after the adoption of directive 2010/32/EU. Methods: Medical records of 539 HCWs were evaluated during their occupational medical examination at the Tor Vergata teaching hospital (PTV). All subjects were screened for specific viral markers: Hepatitis B surface antibodies (anti-HBs IgG), antibodies to hepatitis core antigen (anti-HBc IgG), and hepatitis B surface antigen (HBsAg). Data regarding needlestick injuries were collected by the prevention service team during the same year. Results: In this sample population, we found five subjects (0.9%) positive to the HBsAg, and most of them (four) were born in foreign countries. Moreover, seven subjects (1.3% of our population) were HBsAg-positive and anti-HBc-positive. A protective anti-HBs titer was found in 462 out of 527 (85.7%) subjects. The risk of being serologically unprotected was higher in males and subjects aged 40 years or older. The nurses were more protected than other healthcare professionals considering the anti-hepatitis B surface antibody titer. In 2018, 16 needlestick injuries were reported among our population of HCWs, with a global risk of 2.9% per year. Conclusions: Although hepatitis B virus (HBV) infection rate among HCWs was similar to that of the general population, the risk of HBV transmission in HCWs was likely to be high due to suboptimal vaccination coverage.

Gur-Arie R, Davidovitch N, Rosenthal A. Intervention hesitancy among healthcare personnel: conceptualizing beyond vaccine hesitancy. Monash Bioeth Rev 2022; 40:171-187. [PMID: 35306625 PMCID: PMC8934537 DOI: 10.1007/s40592-022-00152-w] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Revised: 11/18/2021] [Accepted: 02/01/2022] [Indexed: 10/27/2022]
Abstract
We propose an emerging conceptualization of "intervention hesitancy" to address a broad spectrum of hesitancy to disease prevention interventions among healthcare personnel (HCP) beyond vaccine hesitancy. To demonstrate this concept and its analytical benefits, we used a qualitative case-study methodology, identifying a "spectrum" of disease prevention interventions based on (1) the intervention's effectiveness, (2) how the intervention is regulated among HCP in the Israeli healthcare system, and (3) uptake among HCP in the Israeli healthcare system. Our cases ultimately contribute to a more nuanced conceptualization of hesitancy that HCP express towards disease prevention interventions. Our case interventions included the seasonal influenza vaccine, the Mantoux test, and the hepatitis B (HBV) vaccine. Influenza and HBV are vaccine-preventable diseases, though their respective vaccines vary significantly in effectiveness and uptake among HCP. The Mantoux test is a tuberculin skin test which provides a prevention benchmark for tuberculosis (TB), a non-vaccine preventable disease. We conducted semi-structured interviews with relevant stakeholders and analyzed them within Israeli and international policy context between 2016 and 2019, a period just prior to the COVID-19 pandemic. We propose the conceptualization of "intervention hesitancy"-beyond "vaccine hesitancy"-as "hesitancy towards a wide range of public health interventions, including but not limited to vaccines". Results suggested that intervention hesitancy among HCP is rooted in weak trust in their employer, poor employment conditions, as well as mixed institutional guidelines and culture. Conceptualizing intervention hesitancy expands the ability of healthcare systems to understand the root of hesitancy and foster a supportive institutional culture and trust, cognizant of diverse disease prevention interventions beyond vaccination.

Night Shift Work Is Associated with Reduced Rate of Humoral Response Following Vaccination for HBV. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19148834. [PMID: 35886686 PMCID: PMC9320326 DOI: 10.3390/ijerph19148834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 07/15/2022] [Accepted: 07/19/2022] [Indexed: 11/17/2022]
Abstract
Night shift work has been associated with cardiovascular and metabolic disease, endocrine and immunological disorders. Published studies have reported that a reduced total sleep time with sleep-wake cycle alterations were associated with a reduced rate of humoral response following vaccination. Our study aimed to evaluate the association between night shift work and serological status for HBV among workers employed in a university hospital in Rome. We evaluated medical records of 986 HCWs working at Tor Vergata Policlinic of Rome. We screened all study subjects for anti-HBs IgG, anti-HBc IgG and HBsAg. Serological protection for HBV was evaluated in relation to sex, age group, job task, risk setting and night shift work status. Protective titer was found in 856 (86.8%) study participants and the mean titer was significantly high in females, in subjects aged less than 40 years, in night shift workers and in high-risk setting workers. After adjustment for study covariates, night shift work was no longer associated with an HBV-protective titer. This finding suggests that a vaccination strategy for dampening HBV transmission should be carefully addressed in health care workers (HCWs) doing night shift.

Abstract
BACKGROUND Despite improvements in public health and antiviral treatments, vaccination is still the most effective means of prevention of hepatitis B virus (HBV) infection. However, little is known about the duration of protection given by the anti-HBV vaccine. Healthcare workers represent a category at risk not only of contracting infection but also of being a source of contagion to patients. OBJECTIVES To assess individual responses to the anti-HBV vaccine and duration of protection 10 years after its administration in a cohort of healthcare workers employed by the University Hospital 'G. Martino' in Messina, Italy. METHODS One hundred and seventy medical staff who had been vaccinated following an incident carrying risk of HBV infection were included in this study. The group was followed over a 10-year period, and HBV antibody levels were assessed using an automated microparticle enzyme immunoassay. RESULTS Protective antibody levels (≥10 mIU/ml) were found in 65% of subjects who had completed the full vaccine schedule (three doses) and in 35% of subjects who had only received one or two doses of anti-HBV vaccine. Moreover, 10 years after vaccination, HBV antibody levels were inversely related to age at vaccination (P < 0.001). No differences were found between males and females. CONCLUSIONS This study, in line with the literature, shows the importance of completing the full vaccine schedule (three doses). Moreover, in order to have an effective and durable antibody response and avoid the risk of contracting HBV after an injury at work, it is important to recommend anti-HBV vaccination at a young age, ideally during childhood in accordance with the national vaccination policy.

Abstract
AIM The aim of this study was to determine the prevalence of hepatitis B and the risk factors in Morocco. STUDY DESIGN A total number of 16,634 individuals were screened for HBsAg using the Murex HBsAg Version 3 assay and were interviewed using a structured standard questionnaire to collect information about risk factor. RESULTS Two hundred seventy-six subjects were positive for HBsAg, the prevalence of HBV infection was 1.66%. Using a structured standard questionnaire we reported that sexual behaviours (43.84%) are among the main risk factors for HBV transmission. CONCLUSION This study indicates that the prevalence of HBsAg in Morocco is currently estimated at 1.66% in the active population. The risk factors for HBV infection identified here indicate that prevention is the most cost-effective method for successfully controlling HBV infection, so vaccination remains the best way to control this infection and its related complications.

Abstract
This article will focus on the impact caused by chronic viral hepatitis B and C globally and will discuss public health measures that have to be implemented in order to prevent and control these diseases. Chronic viral hepatitis is a major global public health problem, an important cause of morbidity and mortality from sequelae which include chronic hepatitis, cirrhosis and primary liver cancer. Being a 'silent' disease, the contribution of chronic hepatitis to global morbidity and mortality is generally underestimated. Hepatitis B and C prevention and control should seek to reduce both the incidence of new infections and the risk of chronic liver disease. A comprehensive public health prevention programme should include the prevention and detection of HBV and HCV infections, the diagnosis and control of viral hepatitis related chronic liver disease, conducting surveillance and monitoring the effectiveness of prevention activities, and setting up a research agenda.

Abstract
The prevalence of hepatitis infection among the Kosovarian population is largely unknown. The aim of the study was to evaluate the prevalence and risk factors of hepatitis A, B, C, and D (HAV, HBV, HCV, HDV) infection among the general population and in a group of health care workers in the Kosovo region. Overall, 1,287 participants were recruited, 460 males (36%) and 827 females (64%). Health care workers accounted for 253 individuals (20%), 301 were blood donor candidates (23%), 334 were pregnant women (26%), and 399 (31%) were subjects who had been examined in two clinics for routine laboratory testing. The prevalence of total anti-HAV was 88.6% (95% CI: 86.69-90.25). Prevalence of anti-HAV among children up to 10 years was 40.5% (95% CI: 29.6-53.15), reaching 70% (95% CI: 62.25-77.10) in the 11-20 age group. Age, living in rural areas and unemployment were factors associated with higher risk of HAV infection. HBsAg was detected in 2.4% (95% CI: 1.57-3.38%) of the study sample, with a significant age trend (P-value:0.0110). Positivity for total anti-HBc was detected in 18.4% (95% CI = 16.27-20.59) of the subjects. Ninety-three subjects (7.2%) were positive for anti-HBs alone. An association between age, HSV-2 positivity, working nurses and HBV infection has been observed. One patient was HDV positive. The prevalence for HCV was 0.5% (95% CI: 0.22-1.12%). HAV infection seems to be high-intermediate, while HBV shows an intermediate endemicity. It is necessary to highlight the importance of an immunization strategy against HAV and HBV in reducing the incidence of the infection. The prevalence for HCV was very low.

Abstract
OBJECTIVE Health science students are commonly exposed to some infectious agents, including hepatitis A virus (HAV) and hepatitis B virus (HBV), which may cause substantial morbidity and even deaths. The identification of prevalence and risk factors is essential for implementing efficacious preventive measures. A serological survey was performed among medical students of Adnan Menderes University Medical Faculty to determine the prevalence of antibodies against HAV and HBV, and, as a secondary objective, to determine risk factors for acquisition of these infections. METHODS Nearly all students were included in the study. All participants completed a structured questionnaire that assessed demographic and socio-economic characteristics. Anti-HAV IgG, anti-HBc IgG, HbsAg and anti-HBs were tested using commercially available Elisa kits. RESULTS A total of 247 students, 146 (59.1%) male and 101 (40.9%) female, were included in the study. The prevalence of anti-HAV IgG was detected as 64%. Number of siblings and place of residence were detected as independent factors affecting the anti-HAV seropositivity. The prevalence of anti-HBc IgG was detected as 7.3%. Among the students positive for anti-HBc IgG, 5 (2%) students were HBsAg positive and the other 13 (5.3%) were anti-HBs positive. HBV infection in household members, risky sexual behaviour and vaccination were independent factors affecting the prevalence of anti-HBc IgG positivity. CONCLUSIONS The high susceptibility of medical students and their increased risk of clinical HAV and HBV infection identify a need for primary prevention through the administration of vaccination in this group in western Turkey.

Abstract
PURPOSE OF REVIEW In this review the recent literature on the topic of immunization of healthcare workers is assessed. The emphasis lies on immunizations that are directly related to the risks of healthcare workers in the workplace. RECENT FINDINGS Acceptance of influenza immunization by healthcare workers remains too low, whereas other preventive measures such as hepatitis B vaccination are usually not disputed. Efforts to improve the knowledge of healthcare workers about influenza, its epidemic potential and clinical consequences have contributed to higher immunization rates in some hospitals. Immunization against varicella zoster virus does not result in immunity in all vaccinated persons. This lack of complete protection has infection-control implications, namely the recommendation to wear a mask when caring for clinical cases, regardless of the immunization status. The topic of immunization of healthcare workers has recently been dominated by the discussion of smallpox vaccination, which was promoted by the American public-health authorities for some groups of healthcare workers. SUMMARY Immunization is a preventive measure that is highly cost-effective. Healthcare workers are responsible for the safety and well-being of their patients and should do their utmost to prevent the transmission of infectious pathogens to them. Another positive result of the adherence of healthcare workers to the recommended immunization schedule is the improved self-protection at the workplace. Immunization against some highly contagious infectious agents has been recommended for many years. The list is now being expanded again by the recommendation of smallpox vaccination. Regarding this indication, several questions and safety issues must be resolved in order to positively influence the currently rather sceptical attitude of healthcare workers towards this vaccine.

Abstract
The seroprevalence of viral hepatitis in healthcare workers has important public health implications. To assess the risk factors for the acquisition of viral hepatitis in an unvaccinated cohort from an hyperendemic region, 567 healthcare workers from a large hospital in the capital of the Republic of Yemen were interviewed and tested for serological markers of infection with viral hepatitis. 54/543 (9.9%) tested positive for hepatitis B surface antigen (HBsAg), 174/543 (32.0%) had positive hepatitis B core antibodies (anti-HBc), and 19/546 (3.5%) had hepatitis C antibodies (anti-HCV). Age (OR = 1.04, 95% CI 1.02-1.06), male sex (OR = 2.0, 1.32-3.03), and occupation (healthcare workers not carrying out exposure prone procedures, OR = 1.61, 1.06-2.44) were found to be independent predictors for the likelihood of detecting either HBsAg or anti-HBc by multivariate logistic regression analysis. No independent risk factors for anti-HCV positive status were identified. Our findings support the adoption of universal HBV immunisation programmes and infection control precautions. The absence of known risk factors predicting anti-HCV positive serostatus suggests the main mode of transmission of hepatitis C in this cohort in the Yemen remains undiscovered.
