Abstract Background Both hepatitis B virus (HBV) infection and schistosomiasis are important public health problems in China. Concurrent infection between HBV and schistosomiasis is often observed in areas where schistosomiasis is endemic. The aim of this study was to determine the prevalence of schistosomiasis and HBV in schistosomiasis-affected areas, to explore whether schistosomiasis patients are more susceptible to HBV and to determine if the prevalence of HBV in high-endemic areas of schistosomiasis is higher than in low-endemic areas. Methods A total of 6526 participants from 13 villages in Hubei province were included in a cross-sectional study and blood samples were collected and examined. Qualitative variables were compared between groups using Pearson’s chi-squared test or Fisher’s exact test as appropriate. Results Of the 6526 participants, the overall prevalence was 8.27% for schistosomiasis and 2.67% for HBV. The prevalence of hepatitis B among participants who were Schistosoma antibody positive (25.37%) was higher than the prevalence in participants who were Schistosoma antibody negative (0.62%; χ2=1169.358, p<0.001, odds ratio 54.659). We also observed that there was no difference in the prevalence of hepatitis B between males and females in areas where schistosomiasis was endemic (χ2=1.827, p=0.177), but the prevalence of hepatitis B in middle-aged people was higher than in other age groups (χ2=47.877, p<0.001). Conclusions There was an association between schistosomiasis and HBV infection. However, more work is needed to find the causal relationship between schistosomiasis and HBV infection.

Abstract Background According to 2016 World Health Organization and United Nations Children’s Fund country estimates, Eritrea has overall high vaccination coverage with immunization rates for three doses of diphtheria/tetanus/pertussis and polio vaccine of 95%, for two doses measles vaccine of 85% and for three doses hepatitis B vaccine of 85%. If confirmed, this could imply that routine basic vaccination of newly arrived Eritreans could be safely omitted. Methods We used stored serum samples from two cross-sectional studies that screened newly arrived Eritrean refugees for infectious diseases. Consenting refugees aged 16 years and older who registered in one of three neighbouring cantons in northwestern Switzerland were enrolled between January 2016 and December 2017. Antibody titers against the following vaccine-preventable diseases were measured (applied thresholds for seroprotection in brackets): diphtheria (>0.1 IU/ml), tetanus (>0.1 IU/ml), measles (>150 mIU/ml), rubella (only for women, >11 IU/ml), varicella (>50 mIU/ml), hepatitis B [hepatitis B surface antigen (HBsAg) Index >0.9, Hepatitis B core antibody (anti-HBc) Index >0.9 and antibodies to HBsAg (anti-HBs) >10 IE/L]. Differences between sex and age groups (≤25 and >25 years) were measured by Fisher’s exact test. Results We analysed samples of 133 study participants (20 women, 15%) with a median age of 25 years (range 16–61). Rates of seropositivity were as follows for women/men, respectively: diphtheria 57.9%/74.8% (difference non-significant), tetanus 94.8%/41.1% (P < 0.001), measles 73.7%/76.6% (non-significant), rubella in women 78.9%, varicella 89.5%/95.3% (non-significant), anti-HBc 15.8%/26.2% (non-significant) and anti-HBs 15.8%/17.8% (non-significant). Conclusion Seroprevalence for vaccine-preventable infections did not meet levels required to confer herd immunity in any of the human-to-human transmissible diseases that were studied. In general, the strategy proposed by the Federal Office of Public Health to offer basic immunization to all newly arrived refugees, including newly arriving Eritrean refugees, is justified.

Objective: To evaluate patient perception of the smile focused on analysis of the upper incisors. Design: Cross-sectional study. Setting: Department of Clinical and Social Dentistry at Federal University of Paraíba, João Pessoa, Brazil. Participants: The sample consisted of 135 individuals (73 women and 62 men). Methods: Images with different characteristics associated with the incisal edges were shown at random and analysed using a Likert scale. Data were analysed using the Chi-square test or Fisher’s exact test with a statistically significant difference ( P < 0.05). Results: Smile I (difference of 1.5 mm in relation to the central incisor and lateral) was considered the most aesthetic, while Smile III (no difference in height between the central and lateral incisors) was the least aesthetic. A significant difference was found between perception of smile II (difference of 1 mm in relation to the central incisor and lateral) and age groups ( P < 0.005), with 31% (n = 13) of individuals aged 45–64 years considering smile II as not pleasant, 4.4% (n = 2) aged 15–24 years and 8.3% (n=4) aged 25–44 years and 4.4% (n = 2) aged 15–24 years considering the same. A significant difference was also found in relation to educational background of the assessor and smile perception, with smile III ( P = 0.0441) and smile IV ( P = 0.0053) considered the most aesthetic ( P = 0.0116). Conclusion: The smile considered most attractive among the sample was that with 1.5 mm steepness between the central and lateral incisors, while a flat smile arc was considered least attractive.

Background & objectives: Introducing a nucleic acid test program is aimed to diagnose and reduces the risk of viral infection or transmission. DNA assay for HBV can detect infection in the windows period, chronic occult infection and can discriminate between active and inactive HBV infection. This cross-sectional study designed to diagnose, analyze HBV infection and to differentiate active from inactive infection based on viral DNA detection. Methods: Blood samples were collected from 256 patients previously diagnosed on the clinical ground as hepatitis B seropositive in Erbil Central Lab. The viral nucleic acid quantitative assessment was done for the collected samples using RT-PCR. Q-square was performed for statistical analysis. Results: Out of 256 collected blood samples 93 (36.3%) showed HBV-DNA positive titers above 50 IU/ml. Among positive subjects, 67 (72.04%) was categorized as inactive carriers (˂ 2000-20.000 IU/ml HBV-DNA titers). Conclusions: The data produced from this study confirmed the importance of the RT-PCR technique in sensitivity and reliability as a superior diagnostics tool specifically in differentiating active from inactive HBV carriers.

Background. Mosquito-borne diseases constitute an important cause of morbidity and mortality. The use of personal protective measures (PPM) like mats, bednets, screening, repellents, liquid vaporizers, mosquito coils, and so forth has been advocated as an effective tool in control of mosquito-borne diseases, but data about the safety profile of personal protective measures is still scarce.Objective. To study the usage and side effects of personal protective measures against mosquitoes among current users in Delhi.Materials and Methods. A community-based cross-sectional study among 350 adult individuals selected by systematic sampling method. Data was collected using pretested semistructured questionnaire after taking written informed consent. Data was analysed using SPSS version 17. Chi-square/Fisher’s Exact test was used for qualitative variables to find association andPvalue <0.05 was considered significant.Results. Out of 350 families selected, 210 belonged to rural area and 140 to urban area. Personal protective measures were used by 219 (62.5%) subjects. Liquid vaporizer was the most preferred method (41.4%). Most common perceived side effect of personal protective measures was headache (7.7%). Other perceived side effects were cough (3.2%), sore throat (2.7%), allergy (1.3%), and eye irritation (0.9%) predominantly among coil users.Conclusion. There is a need to have a close watch for side effects of personal protective measures among users. Further research is also needed to develop safe and effective personal protective measures against mosquitoes.

Background. Coinfections are becoming common risk factors that may contribute to the increased burden of morbidity in pregnancy. The aim of this study was to assess the seroprevalence of coinfections of malaria, hepatitis B (HBV), human immunodeficiency virus (HIV), and syphilis among pregnant women attending antenatal clinics (ANC) in the Tamale Metropolis. Methods. By means of rapid diagnostic tests (RDTs), pregnant women attending the Tamale Teaching Hospital (TTH) were screened for malaria, HBV infection, HIV infection, and syphilis from March 2013 to February 2015. Haemoglobin (Hb) values, sickling, and glucose-6-phosphate dehydrogenase deficiency (G6PDd) statuses were also assessed using full blood count (FBC), sodium metabisulphite, and methaemoglobin reduction tests, respectively. Logistic regression analysis was performed to estimate the risks/odds ratios (ORs) for the coinfections and other variables (age, gravidity, and time of the first ANC visit) with 95% confidence intervals (CIs) and set p values for accepting any differences at <0.05. Results. Within the two-year study period, data were collected from 3,127 pregnant women. The mean age (SD) of the pregnant women was 28.5 (±5.0) years. Of the total number, seroprevalence was high for malaria (11.6%) and HBV infection (4.2%) and low for HIV infection (1.0%) and syphilis (0.4%) monoinfections. Mal/HBV coinfection was higher (0.7%) when compared with Mal/HIV (0.1%), Mal/syphilis (0.0%), HBV/HIV (0.0%), HBV/syphilis (0.1%), and HIV/syphilis (0.0%) coinfections. The mean Hb (g/dl) for the women with the four monoinfections was significantly different from one another (p=0.009). Pregnant women with malaria infection were about 2 times more likely to be coinfected with HBV even after adjusting for potential confounders (adjusted odds ratio (AOR) = 1.66, 95% CI = 1.04–2.65, p=0.031). Those in their third trimester and visiting the ANC for the first time were significantly less likely to be infected with HBV (AOR = 0.45, 95% CI = 0.28–0.73, p=0.001), with malaria/HBV coinfection (AOR = 0.09, 95% CI = 0.01–0.68, p=0.020), and with any coinfection (AOR = 0.19, 95% CI = 0.06–0.63, p=0.007). Conclusion. A comparatively high seroprevalence of malaria and its coinfection with HBV in pregnant women was observed in this study. Considering the effects that both malaria and HBV have on the liver, it would be expedient to conduct further studies to assess liver function among malaria/HBV-infected individuals, while interventions to prevent coinfections among pregnant women are intensified.

Abstract Background: Meningioma is the most common intracranial tumor in adults. In addition to the extent of tumor surgical resection and WHO grade, angiogenesis is a prognostic factor that is influenced by MMP-2. Our study examined the association of these prognostic factors with MMP-2 expression in meningioma. Methods: A cross-sectional study of patients diagnosed with meningioma between January 2008 and December 2017 was conducted. All samples were re-reviewed and subjected to immunohistochemical staining for Ki67, MMP-2, and CD34. Pearson’s chi-squared test and Fisher’s exact test were used to examine the association of MMP-2 expression with the WHO grade and microvascular density (MVD). Results: The study included 99 patients aged 23–75. Most patients were female (73.7%). This study included 85 cases of low-grade meningioma (grade I) and 14 cases of high-grade meningioma (grade II, 11; grade III, 3). The most common subtypes were meningothelial, transitional, and fibroblastic. In total, 62 of 85 patients with low-grade meningioma and 10 of 14 patients with high-grade meningioma exhibited high MMP-2 expression, and the difference in the rates between the groups was not significant. Most patients in this study displayed MVD scores of 1+ (54/99) and 2+ (33/99). Of the 54 patients with an MVD score of 1+, 42 exhibited high MMP-2 expression. MMP-2 was expressed by all patients with meningioma. Conclusion: In the future, more samples are required, in high-grade tumors, to prevent bias, and more specific immunohistochemical markers should be used to evaluate angiogenesis.

Aims: The study was carried out among 120 dentists working in the selected hospitals of Dhaka city to find out the preventive practice on hepatitis B virus (HBV) infection. Methods: A descriptive type of cross-sectional study was carried out involving 120 dentists working in the selected hospitals of Dhaka city from December 2011 to March 2012 to quantify the preventive practice on HBV infection through a pretested semi-structured questionnaire. Results were analyzed by using the software SPSS 16.0 version (Chicago). Then analyzed data were presented according to the variables of the study showing percentage relationship between variables using appropriate statistical method.Results: Mean age of the dentists was 26.43±6.29 (range, 25-45) years where 74.17% were male and 25.83% were female. Among 120 respondents, 20.83% obtained BDS degree along with a postgraduate training (PGT) in any of the respective fields of dentistry. Others obtained MS in dentistry (21.67%), MPH in dentistry (10.83%), PhD in dentistry (9.17%), DDS in dental surgery (10%) and FCPS in dentistry (6.67%). Academic positions of the respondents were 33.33%, assistant professors, 26.67% associate professors, 19.17% medical officers, and 17.5% were lecturers. Majority (93.3%) dentists knew about HBV transmission, prevention, symptoms, risks, and concurrences. Out of them, 87.5% reported having been tested for HBV which was associated with their designations (p=0.013) and more than 75% reported having been vaccinated against HBV. Conclusions: A high level of knowledge and attitude towards practice in the prevention of HBV was found to be very good among the dentists of Dhaka city though seemed it was not always possible to take precaution for handling emergency patients. Further broad scale studies would be needed to have decisive results. DOI: http://dx.doi.org/10.3329/cdcj.v10i1.13831 City Dent. Coll. J Volume-10, Number-1, January-2013

Background The prevalence of hepatitis B viral (HBV) infection in Indonesia is high. The most effective way to control HBV infection is by hepatitis B (HB) immunization. Many studies reported that hepatitis B surface antibody (anti-HBs) seroprotection declines in children > 10 years of age. In addition many factors can influence anti-HBs titer.Objective To measure anti-HBs titer and evaluate possible factors associated with anti-HBs titer.Methods This cross sectional  study was conducted in children 10-15 years of age from ten schools at Tuminting District, Manado, North Sulawesi, from October to November 2014. All subjects had completed the hepatitis B immunization scheme. By stratified random sampling, 105 children were selected as subjects. Data was analyzed with SPSS version 22.Results. From 48 schools, we selected 10 schools from which to draw a total of 105 children, but only 23 (21.9%) children had detectable anti-HBs . Of all subjects, 76 (72.4%)  were female, 78 (74.3%)  had good nutritional status, and 98 (93.3%)  had birth weight ≥2,500 grams. Data from immunization record books showed that 26 (24.8%) subjects received the HB-1 vaccination at ≤7 days of age and 45 (42.9%) subjects had a ≥2 month interval between the HB-2 and HB-3 vaccinations. Multivariate analysis showed that administration of HB-1 at ≤7 days of age  and a ≥2 month interval between HB-2 and HB-3  had significant associations with anti-HB seroprotection in children.Conclusion A low proportion of subjects who had completed the hepatitis B immunization scheme had detectable anti-HBs titer (21.9%). Administration of HB-1 at ≤7 days of age and a ≥2-month interval between HB-2 and HB-3 vaccinations are important factors in anti-HB seroprotection in children aged 10-15 years.
