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

BACKGROUND AND AIMS: 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. MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.

A study of anti-SARS-CoV-2 antibody positivity in Duhok City, Iraq.

INTRODUCTION: The study aimed to investigate the positivity rate of anti-SARS-CoV-2 antibodies and associated factors. METHODOLOGY: Data and blood samples were collected between January 10th and December 30th, 2021 based on COVID-19 infection by using a designated questionnaire. The blood samples were used for the detection of total SARS-CoV-2 antibodies. RESULTS: 743 participants were recruited and 62.58% of them were positive for SARS-CoV-2 antibodies. Among these, 56.34% denied any symptoms of COVID-19. A higher positivity rate was found among females than men (OR = 1.5, CI = 1.1-2.0, p = 0.0073). Participants that had been diagnosed with COVID-19 in the past had a significantly higher prevalence of antibodies, and were nearly four times more likely to develop antibodies (OR = 4.0, CI = 2.4-6.8, p < 0.0001). Interestingly, only 3% of the participants with previous COVID-19 were seronegative while 46.54% were positive for antibodies without having a history of COVID-19 infection. Participants that reported symptoms were 2.6 times more likely to develop antibodies (OR = 2.6, CI = 1.9-3.6, p < 0.0001). Lastly, we found age to be significantly associated with the production of antibodies (CI = 13.3-14.7, p < 0.0001). CONCLUSIONS: The information from this study can be used to mitigate and develop tailored vaccination efforts and plan evidence-based strategies to better mitigate the ongoing COVID-19 pandemic in Kurdistan-Iraq.

A study of SARS-CoV-2 delta variant breakthrough infections and side effects of the Oxford-AstraZeneca vaccine.

Objective: This study aimed to investigate the breakthrough infection rate and safety profile of the AstraZeneca vaccine. Methods: The breakthrough COVID-19 infection rate was defined as a positive polymerase chain reaction test 14 days after the vaccine dose. Safety was assessed as local reactions and systemic events that occurred within 14 days of receiving vaccine doses. Results: The average age of the 265 participants was 43.85 years and 169 (63.77%) were male. . After the second dose, 18 (6.71%) participants contracted the infection. The SARS-CoV-2 delta variant was responsible for all infections but no participants required hospitalisation. We found significant correlations between post-vaccination IgG levels and post-vaccination infection (P = 0.001; odds ratio [OR] = 0.959; 95% Confidence interval [CI]: 0.944-0.974), and between a history of previous infection and post-vaccination infection rates (P = 0.005; OR = 0.1; 95%CI:0.009-0.6). IgG levels were significantly higher in women than in men (P = 0.006) and in patients who developed side effects after vaccination than in those without side effects (P = 0.04). A significant association was found between a history of COVID-19 infection prior to vaccination and IgG levels (P = 0.001). Conclusions: The vaccine is effective in preventing severe disease, with few side effects.

A study of HBV infection and its risk factors in pregnant women in Zakho city, Iraq.

BACKGROUND: Despite vaccine and antiviral treatment availability, hepatitis B virus (HBV) continues to circulate among pregnant women in Iraq. HBV spread is due to many factors. This study evaluated HBV prevalence among pregnant women and Syrian refugees residing in Zakho city, Iraq, and identified risk factors associated with infection. MATERIALS AND METHODS: Demographic data were collected from 2,054 pregnant women via a questionnaire assessing risk factors associated with HBV infection. Blood samples were collected for hepatitis B surface antigen (HBsAg) and were screened using an enzyme-linked immunosorbent assay. RESULTS: Tests revealed that 1.1% of pregnant women in Zakho and 11.3% of Syrian refugees (p = 0.001) were positive for HBsAg. The average age of HBsAg-positive patients was 31.4286 ± 6.6746 years (p = 0.002). Average rates of parity and abortion in HBV-infected subjects were 3.5 ± 2.6874 and 0.1785 ± 0.5479, respectively (p = 0.044 and 0.012, respectively). The following were identified as associated risk factors for HBV infection: nationality, (Zakho versus the city centre), tattoos, and polygamy (p = 0.001, 0.03, 0.007, and 0.001, respectively). No significant associations between HBV prevalence and blood transfusion, prior injection history, dental procedures, or surgical procedures were found. CONCLUSION: The prevalence of HBV infection among Syrian refugees was higher than that of indigenous participants. Several risk factors were significantly associated with HBV positivity, which may facilitate effective preventive program implementation and decrease mother-to-child transmission risk. This will likely reduce infant and childhood HBV chronicity, and mortality rates.

Human papillomavirus (HPV) genotype prevalence and impact of COVID-19 on the HPV prevention program in Duhok city.

Introduction and aims: Human papillomavirus (HPV) is a sexually transmitted virus that can cause cervical cancer. This study aimed to investigate the prevalence of HPV infection, the prevalent HPV genotypes in women and men with recurrent genital infections, and the impact of the coronavirus disease 2019 (COVID-19) pandemic on the HPV prevention program. Materials and methods: This cross-sectional study was conducted in Duhok city, in the Kurdistan Region of Iraq, between January 2018 and September 2020. We recruited patients from an infectious disease clinic, who were married, were older than 18 years, and agreed to participate in this study. A reverse hybridisation-based assay was used to identify the HPV genotypes prevalent in these patients. Results: Among the patients in the study, 20.9% (67/320) tested positive for HPV infection. The HPV prevalence in females was 18.8% (52/276), which was lower than that in males (34.1%,15/44) (p = 0.21). Thirty-six patients (11.3%) were infected with a single HPV genotype, seventeen (5.3%) with two HPV genotypes, eight (2.5%) with three HPV genotypes, and the remaining six (1.8%) with four or more HPV genotypes. The most common genotypes detected among the patients were HPV-6 (7.2%), -11 (3.8%), and -16 (3.4%). The prevalence of all HPV genotype infections was highest and lowest in the 18-25- and 36-45-year age groups, respectively (X 2 = 8.24; p = 0.041). The number of referred patients substantially reduced from 12 patients per month to 1 patient per month during the COVID-19 pandemic. Conclusion: HPV infection was common in the study population. The most common genotypes were HPV 6, 11, and 16, against which vaccines are available. Further population-based studies are needed to investigate the prevalence of such an infection.

Possible COVID-19 reinfection case in Duhok City, Kurdistan: A case report.

Since the discovery of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the coronavirus disease (COVID-19) pandemic has become the most important health-care crisis globally, having spread to millions of people worldwide. Patients who recover from COVID-19 are still susceptible to reinfection. In this report, we present the case of a patient who had recovered from COVID-19. Recovery was defined as the resolution of symptoms accompanied by two consecutive SARS-CoV-2-negative real-time reverse transcriptase-polymerase chain reaction (RT-PCR) test results. Two months after the first infection, the patient tested positive for anti-SARS-CoV-2 antibodies. Three months after this test, the patient presented with mild COVID-19 symptoms that was confirmed by RT-PCR. These findings indicate a possible reinfection case. If the occurrence of reinfections is demonstrated to be true, then it may change the strategy of community-based disease prevention. More research is needed to confirm the concept of reinfection.

Home management scheme for patients with severe covid-19 in Duhok city, Kurdistan region of Iraq: a possible role for family physicians.

AIM: This study investigated the clinical characteristics and outcomes of patients with severe coronavirus disease 2019 (COVID-19) who were involved in the home management scheme in Duhok city. MATERIALS AND METHODS: This prospective descriptive study enrolled Kurdish patients diagnosed with severe COVID-19 between June 1 and November 1, 2020, and were treated at home. RESULTS: The average age of the patients was 59.77 ± 14 years and 51 (56.04%) of them were males. Seven of these patients (7.69%) were smokers. Most patients (72.52%) had one or more comorbidities. Fever (87.1%) was the most commonly presented symptom in older patients. The case fatality rate was 3/91 (3.29%). This rate was not found to be associated with sex, history of smoking, or comorbidities. The age of deceased patients (40 ± 25 years) was significantly lower than that of cured patients (60 ± 13 years) (p = -0.025). CONCLUSIONS: The case fatality rate of patients enrolled in this scheme was comparable to those who received treatment in hospitals. Therefore, this scheme could provide a good alternative for treating patients with severe COVID-19 and family physicians could lead the scheme through the primary care network.

Assessment of knowledge, attitudes, and practices toward COVID-19 virus among university students in Kurdistan region, Iraq: Online cross-sectional study.

BACKGROUND AND AIM: The World Health Organization (WHO) declared the novel coronavirus infection COVID-19 as a pandemic on March 11, 2020. Adherence to infection control measures is potentially influenced by people's knowledge, attitudes, and practices (KAP) about the infection. This project was performed to assess the KAP toward COVID-19 of university students in Kurdistan Region, Iraq. MATERIALS AND METHODS: An online cross-sectional study was performed in April 2020 to evaluate KAP about coronavirus infection among university students in Kurdistan Region, Iraq. A total of 1959 students were recruited in this study and ages ranged from 18 to 55 years old. RESULTS: Among the respondents, 55.03% were female, 93.8% were from Duhok province, and the majority of participants (93.4%) were undergraduate students. The overall correct answer rate of the knowledge questions toward COVID-19 was 75.8% with an average score of 9.1 ± 2.1 SD out of 12. Participants showed better knowledge of infection prevention with around 86.2% correct answers, while the lowermost subscale scores were (67.7%) for questions toward the mode of the transmission of the infection. We found a significant difference in knowledge scores across genders, marital status, program of study, and among different colleges/institutes (P < 0.001). The majority of participants agreed that the local authority will control the infection successfully (69.8%) and showed confidence that the battle against the virus will be won by Kurdistan Regional Government (86.7%). The majority of the recruited sample (93.0%) had not been in any area with crowd and 57.3% used facemasks when leaving out, recently. CONCLUSION: Students demonstrated good knowledge, appropriate practice, and positive attitude about the infection. These findings indicated that local health education plans to improve people's knowledge about the infection are valuable in protecting the community. The results may be helpful in tailoring an educational program for better containment of the infection and halting the spread of the virus.

The impact of COVID-19 pandemic on the care of patients with kidney diseases in Duhok City, Kurdistan Region of Iraq.

BACKGROUND AND AIMS: The coronavirus disease-2019 (COVID-19) pandemic impacted healthcare services for kidney disease patients. Lockdown and social distancing were mandated in Kurdistan, Iraq to combat the transmission of the infection. The report analyzed the impact of the COVID-19 pandemic on kidney disease patient care in Duhok City, Kurdistan Region of Iraq. METHODS: This study took place in the Duhok Kidney Disease and Transplant Center and compared data from February-April 2019 and 2020. RESULTS: The average number of patients visiting the consultation unit per week was reduced from 68.67 ± 13.6, to 33.42 ± 29.36 (P = 0.001) during the pandemic. In the dialysis unit, weekly hemodialysis sessions were reduced from 341.5 to 306.42 sessions (P = 0.002). The number of patients visiting the kidney transplant consultation unit was significantly reduced (135.7 ± 37.7 versus 102.5 ± 26.3; P = 0.005). The number of kidney transplant operations per week was reduced from 1.167 to 0.5 (P = 0.025). CONCLUSIONS: The COVID-19 pandemic interrupted healthcare services and may continue to impart long-term negative consequences for kidney disease patients.

A sharp increase in the number of COVID-19 cases and case fatality rates after lifting the lockdown in Kurdistan region of Iraq.

With the appearance of first cases of Coronavirus disease (COVID-19), strict control measures were implemented in the Kurdistan Region of Iraq to combat the infection. These measures included the closure of schools and universities, the closure of borders and airports, cancellation of public and religious gatherings, and mandatory quarantine for persons returning from traveling abroad. Such measures have played a major role in the control of COVID-19 spread. However, due to social and economic pressures, the government relaxed the lockdown. After relaxing the measures, a sharp increase in the number of patients was noticed. Besides, there was a significant increase in the number of symptomatic patients and the case fatality rate was doubled. In addition, the outbreak and outbreak response led to the loss of trust and a breakdown in relations between the society and local authority. To minimize the consequences for population health, local authority should have a plan that balances between health imperatives and socioeconomic imperatives. Finally, to be successful in controlling the infection, the government must rebuild public trust in the handling of COVID-19 outbreak and compensate people for lost earnings.

Impact of the Covid-19 pandemic on the elimination of hepatitis C virus in Duhok, Kurdistan, Iraq: A retrospective cross-sectional study.

BACKGROUND AND AIM: Infection with hepatitis C virus (HCV) is a public health threat worldwide. The World Health Organization aims to eliminate HCV. However, the coronavirus disease (COVID-19) pandemic has led to a severe compromise in health services, and this has halted efforts to eliminate HCV. Herein, we report our experience with the initiative of HCV elimination in Duhok city, Kurdistan Region of Iraq, with a focus on the effect of the COVID-19 pandemic on the HCV elimination plan. MATERIALS AND METHODS: An anti-HCV antibody test was used to screen subjects. All positive results were then confirmed by reverse-transcription polymerase chain reaction (RT-PCR) testing. All patients with current HCV infection were treated with direct-acting antiviral regimens. RESULTS: During the study period, 459,015 subjects were tested for anti-HCV antibody positivity, with a monthly average of 9,562 tests for HCV. This number dropped to zero during the lockdown period between 1March and 31May 2020. Among the tested samples, 0.29% (1350/459015) tested positive for anti-HCV antibodies. RT-PCR testing of all positive samples revealed that 0.020% (93/459015) were positive. Of the 93 recruited subjects, 3 patients did not complete the treatment course due to the lockdown. All patients who finished the treatment course were cured as determined by sustained virologic response 12 (SVR12) weeks after finishing the treatment course. CONCLUSION: During the COVID-19 pandemic, reductions in health facility utilisation led to a significant decrease in services offered for HCV screening and treatment. Such a decrease in services has had a negative impact on HCV elimination. An urgent plan is needed to resume the services, and strict follow-up is needed for patients whose treatment was interrupted.

Impact of Covid-19 pandemic on surgical practice in Kurdistan, Iraq: An online cross-sectional survey.

INTRODUCTION: The COVID-19 pandemic is a major challenge to healthcare services in the world. It has negatively impacted surgical practice, and health workers. We aimed to assess the impact of the COVID-19 pandemic on surgical practice in the Kurdistan Region, Iraq. METHODS: An online cross-sectional study using an online survey was performed between 13 April to 29 April, 2020 in the Kurdistan Region, Iraq. An online cross-sectional study using an online survey was performed between 13 April to 29 April, 2020 in the Kurdistan Region, Iraq. A total of 241 surgeons, aged 28-70 years (mean range 22.2 ± 7.9 SD), were recruited to this study. The questionnaire was designed to evaluate the impact of the COVID-19 pandemic on surgeons' practices. Participants completed a self-developed online questionnaire. RESULTS: The majority of participants (44.39%) were general surgeons, followed by urologists (17.01%). Approximately 82.57% of surgeons performed surgeries during the COVID-19 pandemic and 60.31% undertook emergency surgeries only. There was no significant difference between men and women (P = 0.41) and different age groups (P = 0.08). Only 28.22% of surgeons had access to full personal protective equipment (PPE), and 41.18% believed that wearing PPEs severely affected their skills. Results also found that surgeons aged between 28 and 34 years were more pledged to the use of PPEs, than other age groups (P = 0.001). The use of PPEs during surgeries was significantly higher in the Sulaymaniyah province (P = 0.001). The surgical services were also severely impacted in the Sulaymaniyah province than in the other provinces (p = 0.001). CONCLUSION: The COVID-19 pandemic severely affected surgical practice in the Kurdistan Region, particularly in the Sulaymaniyah province. Males, and young surgeons showed a higher commitment level for using PPE. Additional training and precautions are needed to increase awareness about COVID-19 among surgeons, and the importance of using PPE during surgery.

Mapping B-cell responses to Salmonella enterica serovars Typhimurium and Enteritidis in chickens for the discrimination of infected from vaccinated animals.

Serological surveillance and vaccination are important strategies for controlling infectious diseases of food production animals. However, the compatibility of these strategies is limited by a lack of assays capable of differentiating infected from vaccinated animals (DIVA tests) for established killed or attenuated vaccines. Here, we used next generation phage-display (NGPD) and a 2-proportion Z score analysis to identify peptides that were preferentially bound by IgY from chickens infected with Salmonella Typhimurium or S. Enteritidis compared to IgY from vaccinates, for both an attenuated and an inactivated commercial vaccine. Peptides that were highly enriched against IgY from at least 4 out of 10 infected chickens were selected: 18 and 12 peptides for the killed and attenuated vaccines, respectively. The ten most discriminatory peptides for each vaccine were identified in an ELISA using a training set of IgY samples. These peptides were then used in multi-peptide assays that, when analysing a wider set of samples from infected and vaccinated animals, diagnosed infection with 100% sensitivity and specificity. The data describes a method for the development of DIVA assays for conventional attenuated and killed vaccines.

Mapping polyclonal antibody responses to bacterial infection using next generation phage display.

Mapping polyclonal antibody responses to infectious diseases to identify individual epitopes has the potential to underpin the development of novel serological assays and vaccines. Here, phage-peptide library panning coupled with screening using next generation sequencing was used to map antibody responses to bacterial infections. In the first instance, pigs experimentally infected with Salmonella enterica serovar Typhimurium was investigated. IgG samples from twelve infected pigs were probed in parallel and phage binding compared to that with equivalent IgG from pre-infected animals. Seventy-seven peptide mimotopes were enriched specifically against sera from multiple infected animals. Twenty-seven of these peptides were tested in ELISA and twenty-two were highly discriminatory for sera taken from pigs post-infection (P < 0.05) indicating that these peptides are mimicking epitopes from the bacteria. In order to further test this methodology, it was applied to differentiate antibody responses in poultry to infections with distinct serovars of Salmonella enterica. Twenty-seven peptides were identified as being enriched specifically against IgY from multiple animals infected with S. Enteritidis compared to those infected with S. Hadar. Nine of fifteen peptides tested in ELISA were highly discriminatory for IgY following S. Enteritidis infection (p < 0.05) compared to infections with S. Hadar or S. Typhimurium.
