Prevalence of Occupational Injury and Knowledge of Post-Exposure Prophylaxis Accessibility among Healthcare Workers in Mogadishu, Somalia

Introduction: Healthcare workers in Mogadishu, Somalia face significant occupational injury risks, particularly needle stick injuries, with 61.1% reporting incidents. This poses a serious threat to their health, leading to infections such as hepatitis B, hepatitis C, and HIV. Despite the high prevalence of injuries, awareness of Post-Exposure Prophylaxis (PEP) accessibility is relatively high, with 84.0% of respondents aware of it. However, there are gaps in knowledge and implementation, as evidenced by variations in availability of PEP. Improving workplace safety measures, providing comprehensive training on injury prevention and PEP protocols, and ensuring consistent availability of PEP in healthcare facilities are crucial steps to safeguard the well-being of healthcare workers in Mogadishu, Somalia. Methods: A cross-sectional study was conducted among hospital workers in Mogadishu, Somalia, focusing on professionals from various healthcare facilities. The study targeted nurses, doctors, laboratory personnel, and pharmacists. Purposive sampling was employed, resulting in a sample size of 383 calculated using Fisher’s sample size formula. Data were collected using coded questionnaires entered into Microsoft Excel 2019 and analyzed with SPSS software to generate frequencies and proportions, presented through frequency tables and pie figures. Results: The study in Mogadishu, Somalia, examined the prevalence of occupational injuries and knowledge of Post-Exposure Prophylaxis (PEP) accessibility among healthcare workers. Findings indicate a high prevalence of injuries, with 61.1% reporting incidents, predominantly needle stick injuries (60.6%). Despite the majority seeking prompt medical attention (72.0%), work-related illnesses affected 53.2% of respondents, notably work-related stress (59.5%). While most received training on injury and illness prevention (68.9%), gaps exist in PEP awareness, with 16.0% unaware of it. Nonetheless, 84.0% were aware, predominantly through health facilities (52.0%). Availability of PEP was reported by 71.3% in healthcare facilities, with variations in shift availability. The majority reported guidelines for PEP use (55.7%). Efforts are needed to bolster PEP awareness and ensure consistent availability in healthcare facilities to safeguard worker health. Conclusion: High prevalence of occupational injuries among healthcare workers, with needle stick injuries being the most common (60.6%). Despite this, 84.0% of respondents were aware of Post-Exposure Prophylaxis (PEP), primarily learning about it from health facilities (52.0%). While 71.3% reported the availability of PEP in their facility, 28.7% noted its unavailability. These results emphasize the need for improved education and accessibility of PEP to mitigate occupational injury risks.

Effectiveness of onsite and online education in enhancing knowledge and use of human immunodeficiency virus pre-and postexposure prophylaxis

BACKGROUND Enhancing awareness and use of pre-exposure prophylaxis(PrEP)and postexposure prophylaxis(PEP)is vital to curb human immunodeficiency virus(HIV)spread.High-risk behaviors prevalent among sexually transmitted infection clinic outpatients underscore the need for increased PrEP/PEP education in this group.AIM To investigate the effects of both onsite and online health education on the knowledge of,and willingness to use,PrEP and PEP among individuals receiving PEP services.METHODS Participants were drawn from a cohort study on PEP service intervention at an STD/AIDS outpatient clinic in designated HIV/AIDS hospitals in Beijing,conducted from January 1 to June 30,2022.Health education was provided both onsite and online during follow-up.Surveys assessing knowledge of,and willingness to use,PrEP/PEP were administered at baseline and again at 24 wk post-intervention.RESULTS A total of 112 participants were enrolled in the study;105 completed the follow-up at week 24.The percentage of participants with adequate knowledge of,and willingness to use,PrEP significantly increased from 65.2%and 69.6%at baseline to 83.8%and 82.9%at the end of the intervention(both P<0.05).Similarly,those with adequate knowledge of,and willingness to use,PEP increased from 74.1%and 77.7%at baseline to 92.4%and 89.5%at week 24(P<0.05).Being between 31 years and 40 years of age,having a postgraduate degree or higher,and reporting a monthly expenditure of RMB 5000 or more were found to be significantly associated with knowledge of PrEP and PEP(both P<0.05).CONCLUSION The findings show that both onsite and online health education significantly improved the knowledge of,and increased willingness to use,PrEP and PEP in individuals utilizing PEP services.

Potential of Arbidol for Post-exposure Prophylaxis of COVID-19 Transmission:A Preliminary Report of a Retrospective Cohort Study

The efficient transmission of severe acute respiratory syndrome-2 coronavirus(SARS-CoV-2)from patients to health care workers or family members has been a worrisome and prominent feature of the ongoing outbreak.On the basis of clinical practice and in-vitro studies,we postulated that post-exposure prophylaxis(PEP)using Arbidol is associated with decreased infection among individuals exposed to confirmed cases of COVID-19 infection.We conducted a retrospective cohort study on family members and health care workers who were exposed to patients confirmed to have SARS-CoV-2 infection by real-time RT-PCR and chest computed tomography(CT)from January 1 to January 16,2020.The last follow-up date was Feb.26,2020.The emergence of fever and/or respiratory symptoms after exposure to the primary case was collected.The correlations between post-exposure prophylaxis and infection in household contacts and health care workers were respectively analyzed.A total of 66 members in 27 families and 124 health care workers had evidence of close exposure to patients with confirmed COVID-19.The Cox regression based on the data of the family members and health care workers with Arbidol or not showed that Arbidol PEP was a protective factor against the development of COVID-19(HR 0.025,95%CI 0.003-0.209,P=0.0006 for family members and HR 0.056,95%CI 0.005-0.662,P=0.0221 for health care workers).Our findings suggest Arbidol could reduce the infection risk of the novel coronavirus in hospital and family settings.This treatment should be promoted for PEP use and should be the subject of further investigation.

Causes of delay in offering rabies post-exposure prophylaxis services in Abadeh district of Iran

Objective:To identify the reasons for delayed reception of post-exposure prophylaxis(PEP).Methods:In this cross-sectional study,a total of 1407 individuals with animal bites who were referred to the Abadeh Rabies Treatment Center were investigated using the census method from January 2012 to December 2018.The patients were divided into two groups based on their delay times to referral and receive PEP:timely referral(less than 48 h after the bite)and delayed referral(equal to or longer than 48 h after the bite).Frequency,Chi-square,and logistic regression tests were used.Results:.The average delay time was(16.33±11.37)h.Low level of education(OR:3.87;95%CI:1.19-12.54;P=0.02),active economic age(21-35 and 36-50 years-old,OR:12.81;95%CI:3.16-51.97;P<0.001 and OR:3.83,95%CI:3.83-58.61;P<0.001 respectively),occupation(OR:9.16;95%CI:1.89-44.29;P=0.006),long distance from the rabies treatment center(OR:3.41;95%CI:2.03-5.72;P<0.001),bites by household and domestic animals(OR:12.22;95%CI:2.29-65.18,P=0.003),superficial injuries(OR:4.51;95%CI:1.38-14.73;P=0.01),and residence in rural area(OR:12.74;95%CI:6.58-24.66;P<0.001)had significant correlations with delayed referral of victims.Conclusions:To reduce the delay time,the high-risk groups should be informed about the importance of timely referral via educational measures.Furthermore,rabies treatment services should be rendered at the nearest possible center.

Objective: To describe and analyze the epidemiological aspects as well as the observance of post-exposure prophylaxis (PEP) of people bitten by a dog and received at the Buanionzi State Health Center from 2014 to 2017. Methods: Descriptive cross-sectional study which took place in two stages. The first interview was an interrogation carried out at the health Center until surgical trimming (100% of cases) followed by PEP (70.3% of cases) according to the Essen protocol. The second time was a 24 h telephone interview after a missed appointment for a dose of PEP. Results: The prevalence was 5.6 bites/10.000 people. The average age was 26.4 ± 18.3 years. Age ≤ 26 years was more concerned with 59.3% of cases (p = 0.006) in which children Conclusion: The rabies risk is potential in Boma. Efforts in terms of public health strategies must be made to reduce it.

Post-Exposure Prophylaxis against HBV and HIV Infection in Health Care Workers

Healthcare Workers (HCWs) are constantly at risk of exposure to viral infections such as hepatitis B virus (HBV), human immune deficiency virus (HIV) and hepatitis C virus (HCV). We aim at demonstrating the results of a three-year period of a surveillance program in Iran with the prospective follow-up of HCWs exposed to blood-borne viruses. HCWs who had experienced an occupational exposure to HBV, HCV or HIV from September 2005 to 2008 were enrolled in the study. Age, gender, route of exposure, type of fluid, type of virus, job, department, working shift, work experience, wearing gloves when exposed, history of HBV vaccination and the serum level of anti HBs antibody were recorded for all participants through an individual interview. Serum samples were taken from both HCWs and the sources of exposure and were tested by enzyme linked immunosorbent assay (ELISA). The data were gathered through questionnaires completed by a nurse under the supervision of a specialist of infectious diseases. In this study, 100 HCWs who were occupationally exposed to HIV, HCV or HBV were included. Most exposures had occurred among nurses (35%), followed by residents (29%), interns (18%), housekeepers (7%), the lab staff (6%), and specialists (5%). Most of the exposures had occurred in emergency (21%) and surgical (20%) wards. The most common route of exposure was percutaneous injuries (77%) and the most common cases had contacted with needles and angiocaths (71.1%) during injection or opening vein routes (21%). Establishing a surveillance system for registering the occurrence of occupational hazardous exposures, performing prophylactic measures and following up the exposed is a necessity in hospitals so that the number of exposures and occupational diseases among the HCWs can be decreased.

Side effects and tolerability of post-exposure prophylaxis with zidovudine, lamivudine, and lopinavir/ritonavir： a comparative study with HIV/AIDS patients

Background In the era of highly active antiretroviral therapy （HAART）, the use of antiretrovirals as post-exposure prophylaxis （PEP） was the most important strategy for preventing occupational exposure to blood or fluids containing human immunodeficiency virus （HIV）. The objective of this study was to retrospectively evaluate the tolerability, safety, and side effects of a HAART regimen containing three antiretroviral drugs, consisting of zidovudine, lamivudine, and Iopinavir/ ritonavir, in healthcare personnel （HCP） who experienced occupational exposure to HIV. Methods The tolerability, safety, and side effects in 26 HCPs who experienced PEP and in 27 HIV/AIDS patients with HAART regimen, AZT＋3TC＋Lpv/r, were evaluated between January 2010 and December 2012. Results The most frequent clinical side effect was fatigue （in 23 cases, 88.5%）, and gastroenterological symptoms were the second most common side effects in HCP with PEP. Liver dysfunction was found in 10 cases （38.5%）, while drug rash was found in 18 cases （69.2%） after PEP. The prevalence of side effects in HCPs who experienced PEP was higher than that in HIV/AIDS patients P 〈0.05. One nurse （3.8%） experienced severe gastrointestinal symptoms, which led to withdrawal of PEP. No HIV infection was found during 6-month follow-up period. Conclusion HCPs who received occupational PEP with triple-drug regimen, AZT＋3TC＋Lpv/r, experienced different side effects, and the tolerability and safety of PEP regimen were good in this cohort.

Negligible risk of inducing resistance in Mycobacterium tuberculosis with single-dose rifampicin as post-exposure prophylaxis for leprosy

Post-exposure prophylaxis(PEP)for leprosy is administered as one single dose of rifampicin(SDR)to the contacts of newly diagnosed leprosy patients.SDR reduces the risk of developing leprosy among contacts by around 60%in the first 2–3 years after receiving SDR.In countries where SDR is currently being implemented under routine programme conditions in defined areas,questions were raised by health authorities and professional bodies about the possible risk of inducing rifampicin resistance among the M.tuberculosis strains circulating in these areas.This issue has not been addressed in scientific literature to date.To produce an authoritative consensus statement about the risk that SDR would induce rifampicin-resistant tuberculosis,a meeting was convened with tuberculosis(TB)and leprosy experts.The experts carefully reviewed and discussed the available evidence regarding the mechanisms and risk factors for the development of(multi)drug-resistance in M.tuberculosis with a view to the special situation of the use of SDR as PEP for leprosy.They concluded that SDR given to contacts of leprosy patients,in the absence of symptoms of active TB,poses a negligible risk of generating resistance in M.tuberculosis in individuals and at the population level.Thus,the benefits of SDR prophylaxis in reducing the risk of developing leprosy in contacts of new leprosy patients far outweigh the risks of generating drug resistance in M.tuberculosis.

Low rate of pre-exposure prophylaxis and post-exposure prophylaxis uptake and high prevalence of transmitted drug resistance among newly diagnosed primary HIV infections in Shenzhen, China: a real-world retrospective study

Background: Understanding the characteristics of newly diagnosed primary human deficiency virus-1 (HIV-1) infection in the context of the post-antiretroviral therapy era and HIV drug prophylaxis is essential for achieving the new target of 95-95-95-95 by 2025. This study reported the characteristics of newly diagnosed primary HIV-1 infection in Shenzhen.Methods: This is a real-world retrospective study. Eighty-seven newly diagnosed primary HIV-1-infected patients were recruited from January 2021 to March 2022 at the Third People’s Hospital of Shenzhen. Demographic, epidemiological, diagnostic, drug resistance, and medical data were described and analyzed.Results: Overall, 96.6% (84/87) of the newly identified primary HIV-1-infected patients were male, including 88.5% (77/87) men have sex with men (MSM), with a median age of 29.0 years (Q_(1)-Q_(3): 24.0-34.0 years);of these, 85.1% (74/87) reported high-risk sexual behaviors with casual partners. The rate of condom usage was only 28.7% (25/87). The overall rate of pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) was 8.0% (7/87, including 4 PrEP and 3 PEP cases) around the potential exposure, although 41.4% of the patients had prior awareness of such interventions. Moreover, only 19.5% (17/87) had previously used PrEP or PEP. Of those, 58.8% (10/17) of the patients obtained drugs from the internet, and only 35.3% (6/17) reported good compliance. A total of 54.0% (47/87) of subjects were diagnosed by the HIV nucleic acid test. Acute retroviral syndrome appeared in 54.0% (47/87) of patients. The prevalence of transmitted drug resistance (TDR) mutation was 33.9% (19/56), including 6 (10.7%) against nucleoside reverse transcriptase inhibitor (NRTI) plus non-nucleoside reverse transcriptase inhibitor (NNRTI), 8 (14.3%) against NNRTI, and 5 (8.9%) against protease inhibitor (PI) only.Conclusions: Owing to the low utilization rate and incorrect usage of PrEP and PEP, massive efforts are needed to promote HIV-preventive strategies in the MSM population. The extremely high prevalence of TDR mutation in this population implies the need for future pretreatment drug resistance surveillance.

An open-label evaluation of safety and tolerability of coformulated bictegravir/emtricitabine/tenofovir alafenamide for post-exposure prophylaxis following potential exposure to human immunodeficiency virus-1

Background: Single-tablet regimen (STR) provides a convenient once-daily regimen for the prevention of human immunodeficiency virus (HIV) infection. Here, we investigated the safety and tolerability of coformulated bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) as a three-drug, STR for post-exposure prophylaxis (PEP) in Chinese individuals.Methods: This was a prospective, open-label, single-arm trial conducted in a sexually transmitted diseases and acquired immunodeficiency syndrome clinic of a tertiary hospital in Beijing, China. Adults requiring PEP were prescribed BIC/FTC/TAF one pill once a day for 28 days. Clinical and laboratory data were collected and analyzed at baseline, weeks 2, 4, 8, 12, and 24.Results: Of 112 participants enrolled in the study, 109 (97.3%) were male and the mean age was 30 ± 8 years. PEP completion was 96.4% (95% confidence interval: 91.1-99.0%). Two participants stopped PEP after 2 days because the source partner was identified as HIV uninfected. One participant was excluded due to hepatitis B virus infection according to the exclusion criteria. One discontinued due to the participant’s decision. No participant acquired HIV through week 24. Adherence was 98.9% (standard deviation [SD]: 3.3%) by self-reporting and 98.5% (SD: 3.5%) by pill count. Only five participants experienced mild clinical adverse events attributed to the study drug (including headache, diarrhea, and nausea) and four participants had elevated serum creatinine (grade 1).Conclusions: A once daily, STR of BIC/FTC/TAF used as PEP was safe and well-tolerated with a high rate of completion and adherence in Chinese. BIC/FTC/TAF may be a good option for PEP.

Impact of clinical pharmacist intervention on rational use of surgical antibiotic prophylaxis in thyroid surgery

In the present study, we aimed to evaluate the intervention effect of prophylactic antibiotic use in thyroid surgery in a large hospital. From 2004 to 2012, 70 patients who underwent thyroid surgery were randomly selected each year. The quality of surgical antibiotic prophylaxis （SAP） was assessed each year in terms of antibiotic ratio, choice, duration, timing, combination, route of administration and so on. The result showed that the SAP ratio was 100% from 2004 to 2010. With our intervention, this SAP ratio was decreased to 45.7% in 2011, and it reached 2.9% in 2012. The AUD was consistently greater than 38 before 2010, while it rapidly declined to 1 in 2012. The number of DDDs per 100 operations was decreased from 431 to 3 after the intervention. The average cost of antibiotic drugs per patient was RMB 350.65 in 2010, whereas it was decreased to RMB 18.51 in 2012. The average duration of hospitalization showed no difference during the intervention. This study indicated that implementation of a multi-disciplinary protocol and clinical pharmacist interventions could improve the rational use of SAP.

Epidemiological Facies of Human Rabies Deaths in Côte d’Ivoire from 2016 to 2022

Introduction: Rabies is a highly fatal viral disease outside the post-exposure prophylaxis (PEP). Data from previous studies and reports from the rabies center show that cases of death from human rabies are regularly reported, despite training measures for health workers, awareness-raising and communities, and the availability of vaccines. Objectives: The aim of this study was to analyse the determinants of human rabies deaths in Côte d’Ivoire from 2016 to 2022. Method: A retrospective cross-sectional qualitative study was carried out from January to August 2023 on all the records of patients who died of human rabies at the Treichville Rabies Center from 2016 to 2022. An analysis of the rabies center’s annual activity reports from 2016 to 2022 was also carried out in order to complete the information gathered from the files. Results: The socio-demographic characteristics showed that out of 148 deaths, children accounted for 47.97% (71) and 66.22% (98) of rabies deaths were male, with an M/F sex ratio of 1.96. In terms of clinical characteristics, in 97.30% (144) of cases, the deceased had presented with furious rabies, and analysis by the Pasteur Institute of Côte d’Ivoire laboratory confirmed 101 cases (92.66%) of human rabies. Geographical distribution showed that cases of human rabies were recorded in 56 health district, and 64% (94) of the deceased lived in rural areas. The main causes of the occurrence of rabies were essentially non-use of post-exposure prophylaxis (PEP) and missed vaccination due to ignorance. Conclusion: In view of these results, control strategies and interventions need to be adapted to the epidemiological characteristics of the disease, using a community-based approach with a view to eliminating dog-transmitted rabies by 2030.
