Objectives: Human Papillomavirus (HPV) is a leading cause of cervical cancer, yet existing social stigmas and unequal access to healthcare compromise its preventability through screening and vaccination. Understanding healthcare professionals' knowledge and perceptions of HPV is pivotal in enhancing the quality and effectiveness of preventive healthcare strategies. This article aims to explore and understand the relationship between healthcare workers' knowledge and stigma towards HPV. Design and Methods: A questionnaire of 27 stigma and 24 knowledge questions was provided for healthcare personnel. Demographic questions were also included. Stigma levels were determined based on a total median score. Fully adjusted multinomial logistic regression models were used to find the correlation between knowledge regarding HPV and the stigma level. Results: Five hundred fifty-two healthcare workers answered the questionnaire. The findings showed that while most participants had adequate to moderate knowledge about the prevention and complications of HPV, they lacked knowledge about symptoms and treatment. Stigma towards HPV disease was evident in some participants, with attitudes varying depending on demographic factors and knowledge level. The model indicated that age, gender, and specific knowledge questions were significantly associated with stigma levels. Interestingly, the presence of knowledge in some areas increased the stigma level. Conclusions: In conclusion, the study sheds light on the stigmatization and knowledge gaps regarding HPV disease among healthcare personnel and, intriguingly, that increased knowledge does not necessarily correlate with decreased stigma. The findings highlight the need for targeted education and training programs to improve healthcare providers' knowledge in these specific areas.

BACKGROUND: Co-infection with other microorganisms such as parasites in patients with COVID-19 can affect the clinical outcome and require prompt diagnosis and appropriate therapy. CASE PRESENTATION: We present a case of an adult male with chest pain, dyspnea, cough, diplopia, and anorexia who was confirmed to have acute COVID-19 pneumonia. 2 weeks prior to admission, a hydatid lung cyst was identified on examination, but the patient refused surgery. Thoracoabdominal computed tomography (CT) revealed a rupture of the lung hydatid cyst and co-infection with COVID-19. The patient has prescribed a treatment protocol for COVID-19 and albendazole. Despite measures taken to manage severe inflammation and decreasing blood oxygen levels, the patient required admission to the intensive care unit (ICU) and intubation. After approximately 3 weeks of hospitalization, the patient was successfully extubated and discharged uneventfully from the hospital. Oral albendazole was prescribed for follow-up treatment. CONCLUSION: Our case highlights the importance of considering hydatid cysts in the differential diagnosis of patients with COVID-19, especially those living in endemic areas.

Objectives: Chiari malformation exhibits well-defined clinical signs, symptoms, and incidence rates in clinical studies. However, cerebellar tonsil ectopia presents with ambiguous symptoms and undetermined incidence rates in numerous studies. Our objective was to determine the incidence of cerebellar tonsil ectopia in individuals with headaches and identify additional clinical symptoms. This aims to improve diagnosis accuracy for clinicians and neurologists, leading to more effective treatment approaches. Methods: A cross-sectional study conducted in 2022 included 2305 participants aged 4-78 years presenting with headache. Chiari malformation was diagnosed using magnetic resonance imaging (MRI) scans, with a definition of cerebellar tonsil herniation extending beyond 5mm into the cervical canal. Results: The prevalence of Chiari malformation was 3.4%, with no significant gender difference (p = 0.72). There was a significant correlation between Chiari malformation and headache exacerbation due to the Valsalva maneuver (p < 0.001) and the presence of vertigo (p < 0.001). No significant association was found between Chiari malformation and accompanying symptoms such as nausea (p = 0.43), photophobia (p = 0.2), phonophobia (p = 0.52), and speech disorders (p = 0.45). Conclusion: These findings suggest a notable prevalence of Chiari malformation among headache patients and its association with specific headache characteristics, such as acute and occipital headaches, exacerbation by the Valsalva maneuver, and the co-occurrence of vertigo. These results underscore the need to consider Chiari malformation in the differential diagnosis of patients presenting with these specific headache features.

MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression through recognition of cognate sequences and interference of transcriptional, translational, or epigenetic processes. Hundreds of miRNA genes have been found in diverse viruses, and many of these are phylogenetically conserved. Respiratory viruses are the most frequent causative agents of disease in humans, with a significant impact on morbidity and mortality worldwide. Recently, the role of miRNAs in respiratory viral gene regulation, as well as host gene regulation during disease progression, has become a field of interest. This review highlighted the importance of various miRNAs and their potential role in fighting with respiratory viruses as therapeutic molecules with a focus on COVID-19.

BACKGROUND AND PURPOSE: Fatty liver is one of the most common pre-existing illnesses; it can cause liver injury, leading to further complications in coronavirus disease 2019 patients. Our goal is to determine if pre-existing fatty liver is more prevalent in hospitalized COVID-19 patients compared to patients admitted before the SARS-CoV-2 pandemic and determine the disease severity among fatty liver patients. EXPERIMENTAL APPROACH: This retrospective study involves a case and a control group consisting of 1162 patients; the case group contains hospitalized COVID-19 patients with positive PCR tests and available chest CT-scan; the control group contains patients with available chest CT-scan previous to the COVID-19 pandemic. Patients' data such as liver Hounsfield unit, hospitalization length, number of affected lobes, and total lungs involvement score were extracted and compared between the patients. RESULTS: The findings indicate that 37.9% of hospitalized COVID-19 patients have a pre-existing fatty liver, which is significantly higher (P < 0.001) than the prevalence of pre-existing fatty liver in control group patients (9.02%). In comparison to hospitalized non-fatty liver COVID-19 patients, data from hospitalized COVID-19 patients with fatty liver indicate a longer hospitalization length (6.81 ± 4.76 P = 0.02), a higher total lungs involvement score (8.73 ± 5.28 P < 0.001), and an increased number of affected lobes (4.42 ± 1.2 P < 0.001). CONCLUSION: The statistical analysis shows fatty liver is significantly more prevalent among COVID-19 against non-COVID-19 patients, and they develop more severe disease and tend to be hospitalized for more extended periods.

BACKGROUND: The coronavirus disease 2019(COVID-19) has affected mortality worldwide. The Cox proportional hazard (CPH) model is becoming more popular in time-to-event data analysis. This study aimed to evaluate the clinical characteristics in COVID-19 inpatients including (survivor and non-survivor); thus helping clinicians give the right treatment and assess prognosis and guide the treatment. METHODS: This single-center study was conducted at Hospital for COVID-19 patients in Birjand. Inpatients with confirmed COVID-19 were included. Patients were classified as the discharged or survivor group and the death or non-survivor group based on their outcome (improvement or death). Clinical, epidemiological characteristics, as well as laboratory parameters, were extracted from electronic medical records. Independent sample T test and the Chi-square test or Fisher's exact test were used to evaluate the association of interested variables. The CPH model was used for survival analysis in the COVID-19 death patients. Significant level was set as 0.05 in all analyses. RESULTS: The results showed that the mortality rate was about (17.4%). So that, 62(17%) patients had died due to COVID-19, and 298 (83.6%) patients had recovered and discharged. Clinical parameters and comorbidities such as oxygen saturation, lymphocyte and platelet counts, hemoglobin levels, C-reactive protein, and liver and kidney function, were statistically significant between both studied groups. The results of the CPH model showed that comorbidities, hypertension, lymphocyte counts, platelet count, and C-reactive protein level, may increase the risk of death due to the COVID-19 as risk factors in inpatients cases. CONCLUSIONS: Patients with, lower lymphocyte counts in hemogram, platelet count and serum albumin, and high C-reactive protein level, and also patients with comorbidities may have more risk for death. So, it should be given more attention to risk management in the progression of COVID-19 disease.

Statistical models provide a quantitative structure with which clinicians can evaluate their hypotheses to explain patterns in observed data and generate forecasts. In contrast, vitamin D is an important immune modulator that plays an emerging role in liver diseases such as chronic hepatitis B (CHB). Therefore, we quantified 25(OH)D3 serum levels in 292 CHB patients tested for their association with clinical parameters. Of 292 patients, 69 (63%), 95 (47%), and 39 (19%) had severe vitamin D deficiency (25(OH)D3 < 10 ng/mL), vitamin D insufficiency (25(OH)D310 and < 20 ng/mL), or adequate vitamin D serum levels (25(OH)D3 20 ng/mL), respectively. In both univariate and multivariate analyses, zinc serum level was a strong predictor of low 25(OH)D3 serum levels (P < 0.001). Results of fitted models showed that lower vitamin D levels were significantly associated with: younger age, lower uric acid levels, HBeAg-positive status, lower calcium levels (p < 0.05). Vitamin D deficiency (<20 ng/ml) or severe deficiency (<10 ng/ml) was observed more frequently among HBV patients (52%). Vitamin D deficiency was observed in most CHB patients. Generally, our results recommend that substitution of vitamin D can be a substitution method in the treatment of patients with HBV-associated disorders.

BACKGROUND: The present study aimed to determine the prevalence of bone density reduction and its associated factors in hemophilia patients in South Khorasan Province in 2018. MATERIALS AND METHODS: This case-control study was conducted on all patients with hemophilia type A with medical records in Hemophilia center in South Khorasan province. A number of 57 eligible subjects who met the criteria were selected based on census method. Thereafter, 60 non-hemophilic individuals who were similar to hemophilic patients in terms of age and body mass index were selected by convenience sampling method. DXA device was used to measure bone mineral density (BMD) in two locations of femoral neck and lumbar vertebrae. Data were analyzed in SPSS software (version 19), using Chi-square, Fisher's exact test, and independent t-test. A P-value less than 0.05 was considered statistically significant. RESULTS: The prevalence rate of bone density reduction in spine bone in hemophilia patients was measured at 31.6% and 13.3% in non-hemophilia subjects (P=0.02); moreover, this rate in hip bone was reported as 7% and 5%, respectively (P=0.65). Relative frequency of bone density reduction in the spine and hip bone was not significantly different among hemophilia patients based on age, severity of hemophilia, vitamin D, hepatitis and smoking (P>0.05). However, a significant difference was detected in terms of body mass index (P<0.05). CONCLUSION: Based on the obtained results, the prevalence of bone density reduction in hemophilic patients was significantly higher, as compared to that of non-hemophilia patients. This necessitates the implementation of drastic preventive measures, prompt diagnosis, timely treatment, and appropriate therapeutic measures.

BACKGROUND: Nonalcoholic fatty-liver disease (NAFLD) is the most common cause of chronic liver disease worldwide. Although NAFLD has been studied extensively, potential risk factors for NAFLD among chronic hepatitis B (CHB) patients and their comparison with healthy individuals have remained understudied in Iran. As such, we examined the association between HBV infection and the development of NAFLD in two groups. METHODS: A case-control study was done on 376 CHB patients and 447 healthy subjects randomly selected from Birjand, South Khorasan province, Iran. We used logistic regression to estimate adjusted ORs with 95% CIs for incidence of NAFLD. Potential risk factors for NAFLD were evaluated while adjusting for age, sex, marital status, and educational level. Also, χ 2 was used to compare demographic characteristics between the two groups. RESULTS: A total of 373 CHB patients (mean age 40.1±12.9 years) versus 447 individuals in the control group (mean age 39.8±13.9 years) were included in this study (p=0.337). Liver characteristics were found to be significantly different in CHB and healthy groups (p<0.05). According to the results obtained from logistic regression, the adjusted OR (95% CI) for NAFLD incidence of comparing HBsAg-positive to HBsAg-negative participants was 0.62 (0.45-0.84). CONCLUSION: The results suggested that HBsAg seropositivity was associated with lower risk of developing NAFLD. This study also revealed that mild cases of fatty liver in carriers of hepatitis B are more common than in healthy subjects. However, moderate and severe cases of this condition are more common in healthy people than in hepatitis B carriers.

BACKGROUND: Ceftriaxone (CTX) is widely used for the treatment of bacterial infections; however, side effects such as gallstone and nephrolithiasis have been reported in children. There is limited information about urinary tract calculi as CTX side effects in adults. Therefore, the present study was aimed to evaluate the incidence of gallstone and nephrolithiasis following CTX administration. METHODS: The present study was conducted in the Vali-e-Asr Hospital. Eighty-four patients with various infectious diseases with different daily treatment (mean ± SD: 4.19±2.54) were included in this study, consisting of 49 females and 35 males. The mean of total doses used in patients was 10.2143 (SD: 5.8585). To detect possible gallstone, gallbladder sludge, and urolithiasis, patients were evaluated by serial ultrasound before and after CTX treatment. Patients with renal and hepatobiliary dysfunction were excluded from the study and did not receive any nephrotoxic drugs during this study. Demographic parameters including age, sex, body mass index, dosage of CTX, as well as the duration of treatment and hospitalization were determined. Statistical significances were determined using Fisher's exact test and independent t-test. RESULTS: Results from our study showed that the incidence of gallstone and nephrolithiasis were 8.8% and 1.5% following CTX administration, respectively. Surprisingly, we found a significant correlation in terms of age between patients with and without gallstone (P=0.03). CONCLUSION: Our findings suggest that the patients' age might play a role in the development of such a complication. This indicates the need for a close monitoring of CTX-treated patients to assess the possible formation of gallstone and nephrolithiasis.

BACKGROUND: Hepatitis B virus, with 8 known distinct genotypes, is one of the most serious health problems which results to liver injuries. The surface gene of Hepatitis B virus completely overlaps with the polymerase gene. Mutations in the RT gene result in changes in the overlapping hepatitis B surface antigen. OBJECTIVES: The present study aimed to evaluate the genotypes and prevalence of mutations in a segment of S and RT gene in HBV isolates in Southern Khorasan, Iran. METHODS: This was a population-based study comprising 5,235 randomized samples for HBV screening. A nested-polymerase chain reaction (PCR) test was followed by direct sequencing, and the sequences blast with present sequences of NCBI database for genotyping. Alignment and phylogenic analysis was performed using MEGA-6 software, and mutation pattern of this segment was finally surveyed in Bioedit software. RESULTS: The mean age was 39.07 ± 14.04 years, with 52.2% female and 47.8% male. All isolates belonged to HBV genotype D, sub-genotype D1. The most amino acid substitutions of surface protein were Q129H (34.42%) and A168V (8.2%), other escape mutants observed in this study were P127L/T, S117G, T125M, S143L, D144E and E164D. In the RT gene, Q149K was the most frequently identified amino acid substitution (9.83%), followed by L122F (8.19%), N118D/T (6.55%), L157M (4.91%), and H124Y (3.27%). CONCLUSIONS: This finding represents an ongoing dominancy of HBV genotype D in Eastern Iran, corresponding to other parts of Iran. There were a lot of variations in the S gene leading to an escape mutation, some of which affected the corresponding area of the RT region.
