AbstractThis was a population based cross-sectional study carried out to estimate and compare the seroprevalence, hidden prevalence and determine the demographic risk factors associated with SARS-CoV-2 infection among adults in the three largest cities of Odisha, India, and ascertain the association with the progression of the epidemic. The survey carried out in August 2020 in the three largest cities of the state of Odisha, India. Blood samples were collected from the residents using random sampling methods and tested for anti- SARS CoV-2 antibodies using an automated CLIA platform. A total of 4146 participants from the 3 cities of Bhubaneswar (BBS), Berhampur (BAM) and Rourkela (RKL) participated. The female to male participation ratio was 5.9:10 across the three cities. The gender weighted seroprevalence across the three cities was 20.78% (95% CI 19.56–22.05%). While females reported a higher seroprevalence (22.8%) as compared to males (18.8%), there was no significant difference in seroprevalence across age groups. A majority of the seropositive participants were asymptomatic (90.49%). The case to infection ratio on the date of serosurvey was 1:6.6 in BBS, 1:61 in BAM and 1:29.8 in RKL. The study found a high seroprevalence against COVID-19 in urban Odisha as well as high numbers of asymptomatic infections. The epidemic curves had a correlation with the seroprevalence.

High Frequency Hearing Loss

Hearing loss (≥26 dB threshold in the better ear), as a common chronic condition in humans, is increasingly gaining attention. Relevant research in China is relatively scarce, so we conduct a population-based study to investigate the prevalence of hearing loss among age groups, genders and ears in Zhejiang province, China, from September 2016 to June 2018.Study designPopulation-based cross-sectional studyParticipantsA total of 3754 participants aged 18–98 years and living in Zhejiang province, China.Outcome measuresPure-tone audiometric thresholds were measured at frequencies of 0.125–8 kHz for each subject. All participants were asked to complete a structured questionnaire, in the presence of a healthcare official.ResultsThe prevalence of speech-frequency and high-frequency hearing loss was 27.9% and 42.9%, respectively, in Zhejiang. There were significant differences in auditory thresholds at most frequencies among the age groups, genders (male vs female: 31.6%vs24.1% at speech frequency; 48.9% vs 36.8% at high frequency) and ears. In addition to the common factors affecting both types of hearing loss, a significant correlation was found between personal income and speech-frequency hearing loss (OR=0.69, 95% CI 0.52 to 0.92), and between hyperlipidaemia and high-frequency hearing loss (OR=1.45, 95% CI 1.02 to 2.07).ConclusionThe prevalence of hearing loss was high among people living in Zhejiang, particularly males, and in the left ear. Moreover, hearing thresholds increased with age. Several lifestyle and environment factors, which can be influenced by awareness and education, were significantly associated with hearing loss.

Studies on pharmacovigilance (PV) activities in Nigeria focused on perceptions of PV among professional healthcare workers are described here. There is paucity of information on pharmacy students’ knowledge about PV activities. Hence, this study, evaluated the knowledge and perceptions of final year pharmacy students about PV activities using descriptive and inferential statistics. A cross sectional study was undertaken in three Nigerian universities with a pretested questionnaire during the period of January and February, 2016. The questionnaire included closed-ended questions on demographic variables and questions designed to achieve the objectives of the study. Data was analyzed with IBM SPSS Statistics 20 and presented in percentages, means, standard deviations and median at 50% percentile. The mean knowledge score of pharmacovigilance and adverse drug reporting for the final year students was 4.25±0.18. There were significant differences in the mean scores of knowledge domain by age groups 21-24 years 4.8±0.70, 25-30 years 6.2 ± 0.84 and >30 years 4.6±0.72 at p=0.001; gender: male 4.1±1.20 and female 4.4±0.98 at (p=0.0001) as well as the current universities attended as follows University 1 with a scrore of 5.1±1.03, University 2 had a mean score of 6.3±0.99 at p=0.0120 and University 3 with a mean score of 4.3±1.01 at p=0.012. Furthermore, significant difference exist in the mean values of pharmacovigilance knowledge between those who had taking some courses in pharmacovigilance (7.3± 0.22) and those who did not (4.7 ± 0.13) at p=0.0001. Generally, the students had inadequate knowledge of PV activities. Therefore, emphasis on relevant PV courses in their curriculum is necessary.Bangladesh Pharmaceutical Journal 20(1): 1-13, 2017

Background: Dental caries is a multifactorial disease with diet being one of the contributing factors. The influence of vegetarianism on the development of caries has scarcely been investigated in the past. Therefore, this study was done to evaluate the association of dental caries with frequency of sugar exposures and vegetarian / mixed diet.Methods: The present cross-sectional study was conducted among 2500 school children of 12 and 15 years age groups selected on the basis of simple random sampling from different schools of the city. Dental caries was recorded using Decayed, Missing and Filled teeth index (WHO modification, 1997) and correlated with the different dietary variables. Subjects were also segregated on the basis of diet: vegetarian and mixed. Statistical analysis was done using Student t-test and Pearson’s Correlation Coefficient.Results: The prevalence of dental caries in the 12 and 15 year age group of subjects consuming mixed diet was 83.36% and 86.47% respectively. It was lower in case of subjects on vegetarian diet. The correlation between DMFS and TSE, FSE and AMSE was found to be statistically significant (p<0.05) in the 12 year age-group. In the 15 year age-group the correlation of DMFS with TSE and LSE was also found to be statistically significant (p<0.05).Conclusions: There was no statistically significant difference in dental caries status among subjects in both the groups (vegetarian and mixed). However, there was significant association between sugar exposures and dental caries among subjects of both the age-groups.

Abstract Objective: The aim of this study was to investigate the long-term outcome of quality of life (QOL) in the lower-limb amputees 10 years after the 2008 Sichuan earthquake. Methods: In the cross-sectional study, 66 lower-limb amputees were recruited. The prosthetics-related QOL was assessed using the Prosthetic Evaluation Questionnaire (PEQ) in terms of the scales of utility, appearance, sounds, residual limb health, perceived response, frustration, social burden, ambulation, and well-being. The score of each PEQ subscale was calculated and compared among the cohorts with different demographic characteristics. Results: The PEQ scores showed that the scales of sounds, residual limb health, and frustration were still low in the lower-limb amputees 10 years after the 2008 Sichuan earthquake. The comparison of PEQ scales among cohorts with different demographic characteristics indicated that the potential demographic risk factors, namely, age, marital status, educational level, living independence, and comorbidity, were associated with prosthesis-related QOL. Conclusions: The prosthesis-related QOL of the lower-limb amputees 10 years after the 2008 Sichuan earthquake has been partly documented in this study. The potential demographic risk factors associated with QOL of amputees were also identified. These findings could enhance the understanding of prosthesis-related QOL of lower-limb amputees sustained in an earthquake and facilitate the optimization of post-disaster rehabilitation strategies.

ObjectiveTo determine the predictors of non-fatal violence or assault among adolescents in rural Bangladesh to inform evidence-based interventions.DesignCross-sectional study.SettingHousehold survey and national census in 51 unions of rural Bangladesh.Participants, methods and main outcome213 782 adolescents aged 11–19 years who reported violence during a population-based survey in 2013. We used logistic regression to determine the prevalence of factors that predict non-fatal forms of violence or assaults among adolescents. Assault or violence was defined as all injuries inflicted directly by another person or resulting from collateral impact over a 6-month recall period.Results457 (0.21%) cases of violence or assault were reported. The adjusted prevalence ratio (PR) of violence was lower among female adolescents compared with males (PR: 0.60, 95% CI 0.47 to 0.78, p<0.001). Compared with the lowest socioeconomic quintile, being in a higher quintile was associated with lower prevalence of violence, with a 39% decrease in the adjusted prevalence of violence among adolescents in highest compared with lowest socioeconomic index (PR: 0.61, 95% CI 0.44 to 0.84). The adjusted prevalence of violence in Chandpur and Comilla districts was 7.30 times and 7.27 times higher respectively than the prevalence of violence in Sirajganj (PR: 7.30, 95% CI 4.07 to 13.10 and PR: 7.27, 95% CI 3.56 to 14.84, respectively). There was no significant difference in the adjusted prevalence of violence occurring in school compared with home (PR: 1.19, 95% CI 0.85 to 1.69).ConclusionMale adolescents may be at an increased risk of suffering violence, and socioeconomic factors and place (districts) are strong predictors of adolescent violence among a selected population in rural Bangladesh. These findings are important in guiding interventions to address the burden of violence among adolescents in communities with similar demographics as our study population. Further research is needed to identify the actual burden of violence among adolescents at national level and to establish an effective violence prevention programme across Bangladesh.

Abstract Objectives Elevated postprandial triglycerides (TG) are a risk factor for cardiovascular disease (CVD). Although some evidence suggests that older adults exhibit greater postprandial TG than younger adults, it is unknown how postprandial lipid tolerance changes across the spectrum of older adulthood. This cross-sectional study examines postprandial TG responses across the spectrum of aging, as well as factors that may modify this response. Methods We are recruiting individuals into four age categories (age 50–59, 60–69, 70–79, 80–89 years), with an equal number of participants and sex distribution in each group. Participants undergo body composition testing via bioelectrical impedance analysis and complete a 130-item food frequency questionnaire. Participants return to the lab after a 10-hour fast and blood is drawn both before and 4 hours after consumption of a high-fat meal (9 kcal/kg body mass; 73% fat, 26% CHO) to determine fasting and postprandial TG. Results Thirty participants (50’s: n = 12; 60’s: n = 11; 70’s: n = 4; 80’s: n = 3) have completed the study (total N = 60). There was no difference (P = 0.52) in BMI across age groups (50’s: 29.5 ± 5.4 kg/m2; 60’s: 29.1 ± 5.5 kg/m2; 70’s: 25.9 ± 3.8 kg/m2; 80’s: 26.1 ± 1.6 kg/m2). There was also no difference (P = 0.68) in body fat (BF%) across age groups (50’s: 37.5 ± 7.2%; 60’s: 39.53 ± 7.0%; 70’s: 43.6 ± 8.2%; 80’s: 39.5 ± 18.1%). Similarly, there was no difference (P = 0.76) in fasting TG across age groups (50’s: 98.8 ± 40.6 mg/dL; 60’s: 117.9 ± 83.3 mg/dL; 70’s: 105.3 ± 39.7 mg/dL; 80’s: 79.7 ± 31.7 mg/dL), nor was there a difference (P = 0.74) in 4-hr TG (50’s: 162.3 ± 70.8 mg/dL; 60’s: 187.5 ± 105.5 mg/dL; 70’s: 181.8 ± 89.6 mg/dL; 80’s: 130.7 ± 55.1 mg/dL). Lastly, there was no difference (P = 0.16) in fruit and vegetable (FV) intake (50’s: 4.4 ± 1.9 servings/day (s/d); 60’s: 8.2 ± 5.5 s/d; 70’s: 6.2 ± 4.6 s/d; 80’s: 7.9 ± 2.4 s/d). Conclusions At this point in the study, it cannot be concluded that there is a significant difference in fasting or postprandial TG across aging strata, possibly due to no differences in BMI, BF%, or FV intake. When complete, this study will provide valuable insight with regard to the impact of aging and other lifestyle factors on postprandial lipemia and subsequent CVD risk.

Background: Intravenous infusions (IV) are a rapid mean of administering drugs. Hospitals are commonplace for their use, but at the same time they have many serious potential complications. This study aims to know the justified use of intravenous infusion among patients of a tertiary care hospital and awareness about its use.Methods: It was a cross-sectional study in which 249 subjects were conveniently studied. Nil per oral, severity of dehydration, vomiting, and diarrhoea was used as confirmatory criteria for using IV Infusions. Questionnaire with verbal consent was used to collect the data. Descriptive statistical analysis was applied to analyse the data and presented as means, frequencies and percentages in the form of tables and figure.Results: Total n249 (100%) subjects, n68 (27.3%) males and n181 (72.7%) females with average age was 24.05±14.21 years participated. Among n116 (46.6%) irrational users, females n76 (30.5%) were more then males n40 (16.1) with significant difference, p= 0.018. However, no significant difference was found among other variables (age groups, profession, education, awareness and rational or irrational use of IV infusion). Majority n249, n204 (81.9%) were not aware of the IV infusion medication error and doctors were most common unjustified prescribers of IV infusion, n105 (90.5%).Conclusions: The study concluded with the more prevalent irrational IV infusion use in our setup. Doctors appeared the dominant prescriber of irrational IV infusion. This statement is astonishing and must not be overlooked. Female gender, adult age, under-grade patients and students are more exposed to irrational IV infusion.

Introduction: To study and compare the changes in the height of dermal papillae in the skin of different age groups in a segment of Pakistani population. Study Design: Cross sectional study. Period: Five months, from July 2010 to November 2010. Setting: Anatomy Department, Army Medical College, Rawalpindi. Materials & Method: Sixty volunteers of both sexes, after fulfilling the inclusion criteria, participated in this cross sectional study. They all gave written informed consent. They were divided into three equal groups according to their ages, Group A ranged in age from 18 – 29 years, Group B from 30 – 49 years, and Group C > 50 years. Punch biopsies were taken from the sun protected upper arm skin, from all volunteers, after giving local anaesthesia. Samples were stained with Hematoxylin and Eosin. They were observed under light microscope. Height of dermal papillae was measured at three random sites in each sample and mean was taken.The mean of all three groups was compared with each other and data was analyzed. Results: The mean of each sample was taken and then final mean of each group was calculated. They were then compared with each other. The mean height of dermal papillae of group A was 98.667µm, that of group B was 83.333µm and the mean height of dermal papillae in group C was 47.33µm. There was significant difference between the three groups and ‘p’-value was less than 0.5. Conclusion: At the end of this study, it was concluded that, the height of dermal papillae reduces significantly with age.
