High Risk Of Occupational Exposure Research Articles

Hepatitis B vaccination status and knowledge, attitude, and practice towards Hepatitis B virus among medical sciences students: A cross-sectional study.

Healthcare staff are at high risk of occupational exposure to Hepatitis B and other blood-borne diseases. Lack of education about the knowledge of Hepatitis B virus contributes to an increase in cases. This study aims to determine the knowledge of the Hepatitis B virus among the medical professionals in Duhok province, Kurdistan Region of Iraq, and to determine their knowledge of the importance of vaccination. This cross-sectional study was conducted in Duhok province, Kurdistan Region of Iraq, among medical science students from November 2022 to February 2023 and a total of 511 students participated in the study. A Self-administered questionnaire comprising 22 items categorized into five sections was distributed to the students either electronically or by paper and pen method. The survey utilized a Five-point Likert scale when assessing respondents' opinions on knowledge, attitude, and practice (KAP). Microsoft Excel and GraphPad Prism 9 were used for statistical analysis. A total of 511 responses were collected from medical, dental, pharmacy, and laboratory students. The average age of the participants was 20.74 ±1.43 years. Among the respondents, only 96 (18.8%) were fully vaccinated against the Hepatitis B virus (received 3 or more doses of the vaccine), while 294 (57.5%) were not vaccinated. Lack of vaccination programs was the major reason for not receiving a vaccination (n = 182, 62%). About 286 (55.96%) of the participants had good knowledge, attitude, and practice on Hepatitis B, manifesting median scores of 26, 18, and 20, respectively. In our study, half of the students were found to be unvaccinated, mainly due to the absence of vaccination programs. Vaccinated students exhibited better knowledge, attitude, and practice toward the infection than non-vaccinated students. Therefore, we recommend the implementation of a vaccination program as well as training on infection prevention guidelines to increase awareness and encourage vaccination.

Needlestick Injuries With Insulin Injections: Risk Factors, Concerns, and Implications of the Use of Safety Pen Needles in the Asia-Pacific Region.

Globally, health care workers (HCWs) are at a high risk of occupational exposure to needlestick injuries (NSIs). Needlestick injuries not only are associated with an increased risk of infections caused by bloodborne pathogens but are also a primary source of emotional distress and job burnout for HCWs and patients. Insulin injection-related NSIs are common among HCWs working in hospitals in the Asia-Pacific (APAC) region and impose a significant burden. Insulin pen needles have a high risk of transmitting infections (at both the patient-end and cartridge end of the sharp) after use. Recapping a needle after administering an insulin injection poses a major risk to HCWs. Currently, several safety-engineered needle devices (SENDs) are available with active or passive safety mechanisms. Passive insulin safety pen needles with dual-ended protection and automatic recapping capabilities have resulted in a significant drop in accidental punctures to HCWs while administering insulin to patients with diabetes. In this article, we have reviewed the burden and common causes of NSIs with insulin injections among HCWs in the APAC region. We have discussed current approaches to address the issues associated with NSIs and the benefits of introducing SENDs in health care settings, including long-term care facilities, nursing homes, and home care settings where patients may require assisted insulin injections. This review also summarizes key strategies/recommendations to prevent NSIs in HCWs and patients with diabetes in the APAC region.

Salivary Cortisol and Anxiety in Canadian Dentists over 1 Year of COVID-19

The dental profession has endured unprecedented disruption amid COVID-19. Novel stressors have included a high risk of occupational exposure to COVID-19, financial losses, and stricter infection prevention and control requirements. The present study investigated the longitudinal impact of COVID-19 on the stress and anxiety levels of a cohort of Canadian dentists (N = 222) between September 2020 and October 2021. Salivary cortisol was selected as a biomarker of mental stress, and 10 sets of monthly saliva samples (2,131 in total) were self-collected, sent to our laboratory in prepaid courier envelopes, and analyzed by enzyme-linked immunosorbent assay. To assess COVID-19 anxiety, 9 monthly online questionnaires were administered, comprising a general COVID-19 anxiety instrument and 3 items regarding the impact of dentistry-related factors. Bayesian log-normal mixed effect models were fitted to estimate the longitudinal trajectory of salivary cortisol levels and their association with the disease burden of COVID-19 in Canada. After accounting for age, sex, vaccination status, and the diurnal rhythm of cortisol secretion, a modest positive association was found between dentists’ salivary cortisol levels and the count of COVID-19 cases in Canada (96% posterior probability). Similarly, the self-reported impact of dentistry-related factors, such as fear of getting COVID-19 from a patient or coworker, was greatest during peaks of COVID-19 waves in Canada; however, general COVID-19 anxiety decreased consistently throughout the study period. Interestingly, at all collection points, the majority of participants were not concerned about personal protective equipment. Overall, participants reported relatively low rates of psychological distress symptoms in relation to COVID-19, a result that should be reassuring for the dental community. Our findings strongly suggest a link between self-reported and biochemical measurements of stress and anxiety in Canadian dentists during the COVID-19 pandemic.

The predictors of occupationally related injury in employees of Pasteur Institute of Iran

Background: Needlestick Injuries (NSI) are a critical occupational risk for healthcare workers. Therefore, the present study investigated the incidence and risk factors of NSI among employees of the Pasteur Institute of Iran, one of the largest and oldest biological research institutes in the country, who are at high risk of occupational exposure to biological agents. Methods: This cross-sectional study included all personnel (565 individuals) of the Pasteur Institute of Iran. Participants answered some questions related to demographic and occupational characteristics as well as occupational exposure to blood and biological products, and occupational protection. Findings: A total of 448 questionnaires were completed. The mean age (SD) and work experience of the participants were 35.62 (9.20) and 9.72 (1.30) years, respectively. A total of 150 individuals had a history of NSI. The mean (SD) ages of participants with and without a history of NSV were 37.40 ± 9.03 and 34.41 ± 8.80 years, respectively (p < 0.001). The occurrence of NSI was related to work experience of more than five years and drinking, eating, or smoking while working. In addition, changing gloves while using the telephone was significantly related to reporting the occurrence of NSI to the department manager. Conclusion: Our findings indicated the relatively high frequency of NSI among the respondents. Despite the importance of personnel training, we did not find the occurrence of NSI or reporting it to be related to attending training courses. Hence, designing efficient preventive and protective measures requires the assessment of the attitudes of the mentioned institute’s personnel toward NSI and its prevention and management.

Post-traumatic stress disorder and depressive symptoms among firefighters: a network analysis.

Firefighters, as first responders with a high risk of occupational exposure to traumatic events and heavy working stress, have a high prevalence of PTSD symptoms and depressive symptoms. But no previous studies analyzed the relationships and hierarchies of PTSD and depressive symptoms among firefighters. Network analysis is a novel and effective method for investigating the complex interactions of mental disorders at the symptom level and providing a new understanding of psychopathology. The current study was designed to characterize the PTSD and depressive symptoms network structure in the Chinese firefighters. The Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) and the Self-Rating Depression Scale (SDS) were applied to assess PTSD and depressive symptoms, respectively. The network structure of PTSD and depressive symptoms was characterized using "expected influence (EI)" and "bridge EI" as centrality indices. The Walktrap algorithm was conducted to identify communities in the PTSD and depressive symptoms network. Finally, Network accuracy and stability were examined using the Bootstrapped test and the case-dropping procedure. A total of 1,768 firefighters were enrolled in our research. Network analysis revealed that the relationship between PTSD symptoms, "Flashback" and "Avoidance," was the strongest. "Life emptiness" was the most central symptom with the highest EI in the PTSD and depression network model. Followed by "Fatigue" and "Interest loss." Bridge symptoms connecting PTSD and depressive symptoms in our study were "Numb," "High alertness," "Sad mood," and "Compunction and blame," successively. The data-driven community detection suggested the differences in PTSD symptoms in the clustering process. The reliability of the network was approved by both stability and accuracy tests. To the best of our knowledge, the current study first demonstrated the network structure of PTSD and depressive symptoms among Chinese firefighters, identifying the central and bridge symptoms. Targeting interventions to the symptoms mentioned above may effectively treat firefighters suffering from PTSD and depressive symptoms.

SG-APSIC1116: Assessing COVID-19 symptoms in infected healthcare workers in Vietnam

Objectives: In early 2021, when the COVID-19 vaccine was scarce in Vietnam, healthcare workers (HCWs) were prioritized for vaccination due to high risk of occupational exposure. However, there is some COVID-19 vaccine hesitancy within HCW communities. Assessing COVID-19 severity among vaccinated and nonvaccinated HCWs would contribute essential information to assure people of vaccine effectiveness and reduce vaccine hesitancy. Methods: We conducted a descriptive cross-sectional study at the National Hospital for Tropical Diseases in Hanoi, Vietnam, from May to June 2021. Clinical and epidemiological data from HCWs with positive polymerase chain reaction (PCR) results were collected. The severity of symptoms were classified according to Vietnam Ministry of Health guideline (Decision no. 3416 issued July 14, 2021) into 5 categories: asymptomatic, mild, moderate, severe, and critical conditions Results: Overall, 25 HCWs qualified for this study (14 women and 11 men), with a median age of 31 years. Among them, 3 HCWs were infected due to community exposure, and the rest were infected due to occupational exposure. Also, 3 HCWs received the Astra Zeneca vaccine before being infected with SARS-CoV-2 (one fully vaccinated with 2 doses and the other 2 had had the first dose). Categorized by the severity of infection, 28% were asymptomatic, 44% had mild symptoms, 20% had moderate symptoms, and 8% experienced severe symptoms. All 3 vaccinated HCWs showed only mild symptoms. Cough and sore throat were the main symptoms recorded (60%), followed by fever (56%). Blood test results did not show significant differences between the severe and mild COVID-19 groups. Conclusions: COVID-19 vaccination reduced the severity of COVID-19 in this small sample of HCWs. Full COVID-19 vaccination is strongly recommended for HCWs to reduce the spread of COVID-19 and to limit the number of cases with severe disease.

An Intelligent Medical Isolation Observation Management System Based on the Internet of Things.

Since COVID-19 (coronavirus disease 2019) was discovered in December 2019, it has spread worldwide. Early isolation and medical observation management of cases and their close contacts are the key to controlling the spread of the epidemic. However, traditional medical observation requires medical staff to measure body temperature and other vital signs face to face and record them manually. There is a general shortage of human and personal protective equipment and a high risk of occupational exposure, which seriously threaten the safety of medical staff. We designed an intelligent crowd isolation medical observation management system framework based on the Internet of Things using wireless telemetry and big data cloud platform remote management technology. Through a smart wearable device with built-in sensors, vital sign data and geographical locations of medical observation subjects are collected and automatically uploaded to the big data monitoring platform on demand. According to the comprehensive analysis of the set threshold parameters, abnormal subjects are screened out, and activity tracking and health status monitoring for medical observation and management objectives are performed through monitoring and early warning management and post-event data traceability. In the trial of this system, the subjects wore the wristwatches designed in this study and real-time monitoring was conducted throughout the whole process. Additionally, for comparison, the traditional method was also used for these people. Medical staff came to measure their temperature twice a day. The subjects were 1,128 returned overseas Chinese from Europe. Compared with the traditional vital sign detection method, the system designed in this study has the advantages of a fast response, low error, stability, and good endurance. It can monitor the temperature, pulse, blood pressure, and heart rate of the monitored subject in real time. The system designed in this study and the traditional vital sign detection method were both used to monitor 1,128 close contacts with COVID-19. There were six cases of abnormal body temperature that were missed by traditional manual temperature measurement in the morning and evening, and these six cases (0.53%) were sent to the hospital for further diagnosis. The abnormal body temperature of these six cases was not found in time when the medical staff came to check the temperature on a twice-a-day basis. The system designed in this study, however, can detect the abnormal body temperature of all these six people. The sensitivity and specificity of our system were both 100%. The system designed in this study can monitor the body temperature, blood oxygen, blood pressure, heart rate, and geographical location of the monitoring subject in real time. It can be extended to COVID-19 medical observation isolation points, shelter hospitals, infectious disease wards, and nursing homes.

Receipt of First and Second Doses of JYNNEOS Vaccine for Prevention of Monkeypox - United States, May 22-October 10, 2022.

Vaccination with JYNNEOS vaccine (Modified Vaccinia Ankara vaccine, Bavarian Nordic) to prevent monkeypox commenced shortly after confirmation of the first monkeypox case in the current outbreak in the United States on May 17, 2022 (1). To date, more than 27,000 cases have been reported across all 50 states, the District of Columbia (DC), and Puerto Rico.* JYNNEOS vaccine is licensed by the Food and Drug Administration (FDA) as a 0.5-mL 2-dose series administered subcutaneously 28 days apart to prevent smallpox and monkeypox infections (2) and has been found to provide protection against monkeypox infection during the current outbreak (3). The U.S. Department of Health and Human Services (HHS) allocated 1.1 million vials of JYNNEOS vaccine from the Strategic National Stockpile, with doses allocated to jurisdictions based on case counts and estimated size of population at risk (4). However, initial vaccine supplies were severely constrained relative to vaccine demand during the expanding outbreak. Some jurisdictions with highest incidence responded by prioritizing first dose administration during May-July (5,6). The FDA emergency use authorization (EUA) of 0.1 mL dosing for intradermal administration of JYNNEOS for persons aged ≥18 years on August 9, 2022, substantially expanded available vaccine supply† (7). The U.S. vaccination strategy focuses primarily on persons with known or presumed exposures to monkeypox (8) or those at high risk for occupational exposure (9). Data on monkeypox vaccine doses administered and reported to CDC by U.S. jurisdictions were analyzed to assess vaccine administration and completion of the 2-dose series. A total of 931,155 doses of JYNNEOS vaccine were administered and reported to the CDC by 55 U.S. jurisdictions during May 22-October 10, 2022. Among persons who received ≥1 dose, 51.4% were non-Hispanic White (White), 22.5% were Hispanic or Latino (Hispanic), and 12.6% were non-Hispanic Black or African American (Black). The percentages of vaccine recipients who were Black (5.6%) and Hispanic (15.5%) during May 22-June 25 increased to 13.3% and 22.7%, respectively, during July 31-October 10. Among 496,888 persons who received a first dose and were eligible for a second dose during the study period, 57.6% received their second dose. Second dose receipt was highest among older adults, White persons, and those residing in the South U.S. Census Bureau Region. Tracking and addressing disparities in vaccination can reduce inequities, and equitable access to and acceptance of vaccine should be an essential factor in planning vaccination programs, events, and strategies. Receipt of both first and second doses is necessary for optimal protection against Monkeypox virus infection.

P138 A decade of cat-transmitted sporotrichosis (CTS) in a tertiary hospital from Curitiba, southern Brazil (2011-21)

Poster session 2, September 22, 2022, 12:30 PM - 1:30 PMObjectivesThis study aims to report the evolution of cat-transmitted sporotrichosis (CTS) and map the distribution of these cases within a tertiary hospital in Curitiba (state capital of Paraná, in southern Brazil).MethodsWe reviewed the medical records of 175 patients seen in a hospital service over a period of 10 years (2011-21). Proven CTS consists of patients that had clinical manifestations after contact with sick cats, microbiological, and/or histopathological evidence of sporotrichosis. CTS was considered probable when patients had clinical signs associated with contact with sick cats that had a microbiological diagnosis of sporotrichosis made by a veterinarian. The confirmed cases in culture were submitted to molecular identification performed by sequencing the locus of calmodulin (CAL), determined by the set of primers 1 (5′-GAR TWC AAG GAG GCC TTC TC-3′) and CL2A (5′-TTTT TTG CAT CAT GAG TTG GAC-3 ′). The study was approved by the local Research Ethics Committee. Data analysis was performed using Statistical software for Windows (Version 8.0, StatSoft InC., Tulsa, OK, USA).ResultsThe diagnosis of proven sporotrichosis was established in 57 patients (32.6%) and the probable diagnosis was verified in 118 patients (67.4%). Among all 175 patients, 171 (98.3%) cases were reported as zoonotic transmission and only 4 (1,7%) as sapronotic (classical pathway). Molecular identification was performed in 35 isolates and in 97.0% (n = 34) of them, Sporothrix brasiliensis was the main etiological agent identified (Fig. 1). Most cases of sporotrichosis were diagnosed between 2019 to 2021 (n = 105, 60%). The incidence rate increased from 0.27 cases/100.000 patients in 2011 to 30.4 cases/100.000 patients in 2021 (until July) and was observed geographic expansion of human cases of CTS in Curitiba in the last decade (accumulated cases 2011-12, 2011-16, and 2011-21 July) (Fig. 2). Prevalence rate was 4.97 cases per 100 000 patients. The majority of the patients were from Curitiba (n = 145, 82.9%). Women were the most affected (63.4% women vs 36.6% men) with the average age of 40 years old (1-87 years old). A total of 12% (n = 21) of the patients were under 18 years old. The prevalence of CTS in patients at high risk of occupational exposure to the disease was 9.7% (n = 17), 9 being veterinarians, 5 veterinary students, 3 pet house workers, and 2 gardeners. The main clinical manifestation was lymphocutaneous (n = 114, 65.1%), followed by fixed cutaneous (n = 43, 24.6%), ocular (n = 13, 7.4%), and mixed forms (n = 5, 2.9%).ConclusionCTS is a public health issue that is aggravated due to the lack of national control programs, unknown prevalence of the disease, lack of knowledge of the population, and health professionals about the epidemic. Besides that, there are difficulties in handling sick cats, lack of diagnosis of human and veterinary cases, and poor access to free medication. In 2011, the first case of CTS was identified in Curitiba, Paraná, Brazil. In 10 years, there has been a significant increase in the number of new cases. Those evidence indicate the continuous dispersion of the disease out of epidemiological control.

Vaccination for Monkeypox Virus Infection in Humans: A Review of Key Considerations.

Monkeypox virus infection in humans (MVIH) is currently an evolving public health concern given that >3000 MVIH cases have been reported in >50 countries globally, and the World Health Organization declared monkeypox a global health emergency on 23 July 2022. Adults (≥16 years old) usually have mild disease in contemporary studies, with a pooled case fatality rate of 0.03% (1/2941 cases). In comparison, poorer outcomes have been reported in children <16 years old (pooled case fatality rate 19% (4/21 cases)), immunocompromised patients, and pregnant women, with high rates of fetal demise in this group. Monkeypox-specific treatments include oral or intravenous tecovirimat, intravenous or topical cidofovir, oral brincidofovir, and vaccinia immunoglobulin, but the overall risk–benefit balance of monkeypox-specific treatment is unclear. Two effective vaccines exist for the prevention of MVIH: modified vaccinia Ankara and ACAM2000. Most probably, vaccination will be a key strategy for mitigating MVIH given the current rapid global spread of monkeypox, the existence of efficacious vaccines, and the uncertain risk–benefit profile of current antivirals. Priority groups for vaccination should include healthcare workers at high risk for occupational exposure, immunocompromised patients, and children. Vaccination strategies include pre-exposure vaccination, post-exposure prophylaxis, and ring vaccination of close contacts.

To study the incidences of needle stick injury among critical care nurses working in rural tertiary care hospital

Needle-stick injuries (NSIs) are a hazard for nursing staff and public health. Nursing workers are at high risk for occupational exposure to blood-borne pathogens via sharp injuries of the needle-stick. Needle-stick injuries (NSIs) are described as penetrating wounds caused by a device that is contaminated with another person’s body fluids. Needle-stick injuries are injuries acquired by needles like -scalp vein needles, hypodermic needles, blood sample collection needles, intracath stylets, lumbar puncture needles used to connect parts of IV delivery systems. Needle-stick injuries (NSIs) form a medium for the transmission of bloodborne infections. Strict use of personnel protective equipment while working in the hospital should be made compulsory. To study incidences of needle stick injury among nurses working in Rural tertiary care Unit, Loni. Ethical approval for this study was obtained from the Institutional Ethical Committee. Seventy-six nurses, who fulfilled inclusion criteria were included and data was obtained through survey. This study involves 76 nursing staff. Of them all, 27(35.5%) nursing staff experienced NSIsThe administration of medication was common action that caused most of needle-stick injuries mentioned by 14 (18.4%) nursing staff. IV cannula was the device that caused many needle-stick injuries reported by 17 (21.1%) nursing staff. Thenursing professionals are the main key players in both elective and emergency situations. There is a quite higher incidence of needle stick injury among critical care nurses. This might be due to handling of emergency cases and attempting to secure the intravenous line or to deliver the medications. Creating awareness and training appropriately is mandatory for critical care nurses.

Health Care Worker Status Is Protective Against Thrombotic Events Associated With COVID-19

Thromboembolic events (TE) are commonly reported complications of coronavirus disease-2019 (COVID-19) infection in admitted patients, contributing to the complexity of patient care, hospital admission, and mortality rates. Health care workers (HCWs) experience high risk occupational exposure to COVID-19 infection, and thus a theoretical increased risk of TE. This study seeks to identify variables associated with increased risk of TE regardless of admission status who tested positive for COVID-19 during the initial surge of the pandemic in an urban setting in both HCWs and non-HCWs.

SARS-COV-2 Screening of Health Care Workers in Brunei Darussalam.

Health care workers (HCWs) are at high risk of COVID-19 infection; therefore, screening is recommended for early detection and management to break the chain of transmission. Globally, multiple strategies have been utilized for the screening of HCWs. This article reports and evaluates an active surveillance and screening strategy for severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) among HCWs following work or nonwork exposures in Brunei Darussalam to prevent health care-associated COVID-19 transmission. In March 2020, the Ministry of Health through the Occupational Health Division adopted an active screening strategy for symptomatic and asymptomatic HCWs, which involved symptom screening, risk assessment, SARS-COV-2 testing, and management following work/nonwork exposure and recent overseas travel, and those with influenza-like illness (ILI) symptoms. Screening frequency was based on the HCWs' symptoms and exposure, with the intent to evaluate all possible sources of exposure. As of December 31, 2020, 821 HCWs were screened, of which 632 (77%) had ILI symptoms and 14 (1.7%) had high-risk occupational exposure. Reverse transcription polymerase chain reaction (RT-PCR) swab testing was carried out on 577 (70.3%) HCWs, with the highest proportion of swabs done on doctors (85.1%; p < .01) due to their workplace exposure (34.3%) and overseas travel (38.7%). By July 2021, Brunei Darussalam had recorded zero cases of COVID-19 among HCWs from occupational exposure. Our strategy of active screening for SARS-COV-2 RT-PCR testing since early in the outbreak has proven to be successful, in combination with infection control practices and public health measures, in the prevention of occupational transmission, thereby facilitating early return to work for HCWs with low-risk exposure and without symptoms.

Proportionate mortality among workers exposed to hardwood dust in Italy.

The main aim of this study is to estimate the impact on workers' health caused by hardwood dust exposure in selected industrial sectors in Italy. Proportionate mortality ratios (PMR) by cancer site were calculated by linking the information on occupational exposure to carcinogens from the Italian national registry (SIREP, 1996-2018) to the national mortality archives (ISTAT, 2005-2018), assuming a Poisson distribution of the data. An elevated proportion of deaths from sino-nasal cancer was found in male exposed workers (PMR=4.25, CI 95%=1.37-13.23). Increased proportions of deaths were also found from stomach cancer in both genders (PMR=3.14, CI 95%=1.41-7.00 women; PMR=1.64, CI 95%=1.22-2.19 men). Although hardwood dust is a known human carcinogen, there are still many high-risk occupational exposure settings. Epidemiological surveillance and continuous monitoring of workers is highly recommended in order to ensure compliance with regulatory obligations and limit the burden of associated mortality causes.

Sero-Prevalence of HBV and its Associated Factors Among Healthcare Providers in Public Health Facilities in Eastern Ethiopia.

Background:Healthcare providers are in high occupational risk of Hepatitis B virus infection than that of the general population because of the high risk of occupational exposure to patients’ body fluids and accidental sharp injuries. There are no large facility-based studies conducted on the prevalence of HBV infection and its associated factors among health care providers in eastern Ethiopia.Objective:This study aimed at investigating the seroprevalence of Hepatitis B Virus and its associated factors among the healthcare providers in public health facilities in eastern Ethiopia.Methods:A facility-based cross-sectional study was conducted among 438 randomly selected healthcare providers in eastern Ethiopia from March to June 2018. Pretested structured questionnaire was used to collect data on socio-demographic characteristics and other risk factors. In addition, a 2.5 ml blood was collected and the serum was analyzed for Hepatitis B surface antigen using the Instant Hepatitis B surface antigen kit. Data were entered using Epidata version 3.1 and analyzed using SPSS statistical packages version 22. Descriptive summary measures were used. Bivariate and multivariable logistic regression was conducted at 95% CI. An association at P-value <.05 was considered statistically significant.Results:A total of 438 (92.02% response rate) health care providers have participated in this study. The prevalence of hepatitis B virus infection was 9.6%. There were no significant differences in the HBV infection rates among healthcare providers with respect to socio-demographic characteristics (P-value >.05). After adjusting for some variables, the following variables remained statistically significantly associated with HBsAg positive result in the multivariable analysis: exposure to body fluids (AOR = 3.0; 95% CI [1.25, 7.05]), history of needle stick injury (AOR = 4.70; 95% CI [2.10, 10.55]), history of operation/surgery (AOR = 4.88, 95% CI [1.43, 16.62]), history of multiple sexual partner (AOR = 7.48; 95% CI [2.08, 26.96]), and being unvaccinated (AOR = 6.09; 95% CI [2.75, 13.51]).Conclusion:This study showed a high prevalence of HBV infection among health care providers in eastern Ethiopia. This is significant because health professionals may be at increased risk of chronic complications and may also be source of infection for their clients and general population during their healthcare practice. Management commitment that should focus on occupational safety and health promotions is necessary.

Association between urinary bisphenol A concentrations and semen quality: A meta-analytic study

Although preclinical research has revealed disrupting effects on male reproductive functions of bisphenol A (BPA), as yet clinical studies have led to inconsistent results. The present meta‑analysis aims to establish the existence and the extent of the association between BPA exposure and semen quality. A thorough search of PubMed, Scopus and Web of Science databases was carried out. Only studies reporting data from multivariable linear regression analyses (β-coefficients with 95% CI), assessing the association between urinary levels of BPA and standard semen parameters were included. Nine studies provided information about an overall sample of 2,399 men. Only the negative association between urinary BPA levels and sperm motility reached statistical significance (pooled β-coefficient = -0.82; 95% CI: −1.51 to −0.12, p = 0.02; Pfor heterogeneity = 0.1, I2 = 42.9%). Yet, such a significance was lost after data adjustment for publication bias, as well as at the sensitivity analysis, when each of the two studies that contributed most to the overall estimate was excluded. In conclusion, the overall estimates of data produced by clinical studies point to a clinically negligible, if any, association between urinary BPA concentrations and semen quality. Further studies in workers at high risk of occupational exposure are warranted to corroborate the herein revealed weak correlation with a worse sperm motility.

Research on the Epidemiology of SARS-CoV-2 in Essential Response Personnel (RECOVER): Protocol for a Multisite Longitudinal Cohort Study.

BackgroundWorkers critical to emergency response and continuity of essential services during the COVID-19 pandemic are at a disproportionally high risk of SARS-CoV-2 infection. Prospective cohort studies are needed for enhancing the understanding of the incidence of symptomatic and asymptomatic SARS-CoV-2 infections, identifying risk factors, assessing clinical outcomes, and determining the effectiveness of vaccination.ObjectiveThe Research on the Epidemiology of SARS-CoV-2 in Essential Response Personnel (RECOVER) prospective cohort study was designed to estimate the incidence of symptomatic and asymptomatic SARS-CoV-2 infections, examine the risk factors for infection and clinical spectrum of illness, and assess the effectiveness of vaccination among essential workers.MethodsThe RECOVER multisite network was initiated in August 2020 and aims to enroll 3000 health care personnel (HCP), first responders, and other essential and frontline workers (EFWs) at 6 US locations. Data on participant demographics, medical history, and vaccination history are collected at baseline and throughout the study. Active surveillance for the symptoms of COVID-19–like illness (CLI), access of medical care, and symptom duration is performed by text messages, emails, and direct participant or medical record reports. Participants self-collect a mid-turbinate nasal swab weekly, regardless of symptoms, and 2 additional respiratory specimens at the onset of CLI. Blood is collected upon enrollment, every 3 months, approximately 28 days after a reverse transcription polymerase chain reaction (RT-PCR)–confirmed SARS-CoV-2 infection, and 14 to 28 days after a dose of any COVID-19 vaccine. From February 2021, household members of RT-PCR–confirmed participants are self-collecting mid-turbinate nasal swabs daily for 10 days.ResultsThe study observation period began in August 2020 and is expected to continue through spring 2022. There are 2623 actively enrolled RECOVER participants, including 280 participants who have been found to be positive for SARS-CoV-2 by RT-PCR. Enrollment is ongoing at 3 of the 6 study sites.ConclusionsData collected through the cohort are expected to provide important public health information for essential workers at high risk for occupational exposure to SARS-CoV-2 and allow early evaluation of COVID-19 vaccine effectiveness.International Registered Report Identifier (IRRID)DERR1-10.2196/31574

A Cross-Sectional Study of SARS-CoV-2 Vaccination Among Employees of an Urban Safety-Net Health Care System.

A Cross-Sectional Study of SARS-CoV-2 Vaccination Among Employees of an Urban Safety-Net Health Care System.

Seroprevalence of SARS-CoV-2 Antibodies in Symptomatic Individuals Is Higher than in Persons Who Are at Increased Risk Exposure: The Results of the Single-Center, Prospective, Cross-Sectional Study.

The present study aimed to assess antibody seropositivity prevalence among symptomatic individuals and individuals with a high risk of occupational exposure to SARS-CoV-2. Participants from Chelyabinsk (Russian Federation) who were at an increased risk of exposure to SARS-CoV-2 (high-risk group, n = 1091) and participants who either had symptoms consistent with COVID-19 or were suspected to have experienced COVID-19 in the past (symptomatic group, n = 692) were enrolled between 28 September and 30 December 2020. Blood samples were tested by enzyme-linked immunosorbent assay D-5501 SARS-Cov-2-IgG-EIA-BEST and D-5502 SARS-Cov-2-IgM-EIA-BEST (AO Vector-Best, Novosibirsk, Russia). The overall seropositivity rate was 28.33–28.53%. SARS-CoV-2 antibodies were detected in 17.23% (adjusted prevalence of 17.17–17.29%) of participants in the high-risk and 45.95% (adjusted prevalence of 45.91–46.24%) in the symptomatic group. Higher IgG and IgM titers were observed in women compared to men, as well as in participants in the symptomatic group compared to those in the high-risk group. The results indicate that the seroprevalence among residents in several Russian regions is low (28.38%) and inadequate to provide herd immunity. The lower seroprevalence among participants in the high-risk group may be attributed to the enforcement of healthcare protocols and the use of adequate personal protective equipment.

Worldwide Prevalence of Occupational Exposure to Needle Stick Injury among Healthcare Workers: A Systematic Review and Meta-Analysis.

Background Healthcare workers are at high risk of occupational exposure to needle stick injury worldwide. Occupational exposure to needle stick injury represents the most common sources of infection such as hepatitis B virus, hepatitis C virus, and human immunodeficiency virus. Thus, this review aimed to determine the career time and previous one-year global pooled prevalence of occupational exposure to needle stick injury among healthcare workers. Methods The review considered articles written in English language and published from 2012 to 2020. The articles were searched using nine electronic databases (PubMed, Google Scholar, CINAHL, MEDLINE, Cochrane library, Web of Science, SCOPUS, MedNar, and ScienceDirect) using a combination of Boolean logic operators (AND, OR, and NOT), Medical Subject Headings, and keywords. Quality assessment was performed to determine the relevance of the articles using Joanna Briggs Institute critical appraisal tools. Several steps of assessment and evaluation were taken to select and analyze the relevant articles. Results The worldwide pooled prevalence of needle stick injuries among healthcare workers during career time and previous one year was 56.2% (95% CI: 47.1, 64.9) and 32.4% (95% CI: 22.0, 44.8), respectively. The career time pooled prevalence of needle stick injuries based on the socioeconomic development and study area was 54.8% and 55.1%, respectively, and one-year pooled prevalence of needle stick injury was 26.0% and 20.9%. Conclusion The review found a high prevalence of occupational exposure to needle stick injury among healthcare workers and suggests the need to improve occupational health and safety services in the healthcare systems.
