Trypanosoma evansi is a well-known hemoprotozoa that infects diverse domestic and wild animals worldwide and caused devastating disease called surra. This research aimed to investigate the seroprevalence of Trypanosoma evansi and its associated risk factors in dromedary camels in North Al-Sharqiya governorate in the Sultanate of Oman.  A total of 4364 serum samples was collected from three willayat in north governorates of Sultanate of Oman; Ibra (926, 21.2%), Qabil (1119, 25.6%) and Bidiyah (2319, 53.1%). Samples were examined for the presence of antibodies against T. evansi using card agglutination test (CATT/T. evansi). Binary logistic regression was used to study the association of T. evansi seroprevalence and risk factors such as location, gender, purpose and age of camels. The overall seroprevalence of T. evansi detected by CATT/T. evansi test was 38% (1659/4364, CI: 36.6-39.5%). There was a significant difference (p=0.001) between location and T. evansi seroprevalence, whereas highest seroprevalence was found in Ibra (49.9%, CI: 46.7-53.1%) followed by Bidiyah (35%, CI: 33-36.9%) and Qabil (34.5%, CI: 31.8-37%). Camels from Ibra were almost two times more likely to have circulating antibodies of T. evansi than camels from Bidiyah (OR=1.89, CI: 1.591-2.168). Also, the results showed a significant difference between seroprevalence and sex (p=0.023), whereas the age of camels was not (p>0.05). To our knowledge, this is the first research that indicated that T. evansi antibodies were circulating among camels in Oman, and further research needs to be tackled to study the molecular characterization of T. evansi and its prevalence in other animal species. Furthermore, cross-sectional studies of T. evansi from different regions in Oman warrant further investigation.

Brucellosis is a worldwide zoonotic disease which is now considered endemic in most parts of Egypt. A cross-sectional study was carried out from December 2018 to February 2020 to investigate the seroprevalence of brucellosis in humans and livestock residing in two regions located in New Valley Governorate, Egypt. A total of 1254 animals (673 cattle, 348 sheep, and 233 goats) and 523 human serum samples were examined for brucellosis using Rose Bengal test (RBT) and then randomly selected sera (15 from cattle, 7 from sheep, 3 from goats, and 45 from humans) were further analyzed by complement fixation test, enzyme-linked immunosorbent assay to compare and detect the sensitivity and specificity of RBT. The prevalence of brucellosis was 0% in cattle, sheep, and goats while it was 23.9% in humans using RBT. Concerning humans, there was a higher percentage of infection in EL Kharga (33.6%). The prevalence of this infection was also at a higher level among individuals aged above 40 years (28.57%). Furthermore, men (26.11%) were more inclined to be inflicted, compared to women (22.5%) with no significant difference. Considering the human occupation, abattoir workers were the most predominant group of people at risk (33.3%), followed by farmers (31.25%) and animal keepers (20.6%) while the lowest prevalence was demonstrated in the housewives where the prevalence was 18.8 %. As a result, risk factors of the age range, locality, time of infection, contact with animals, and occupational groups could significantly affect the prevalence of human brucellosis in the New Valley Governorate. In conclusion, brucellosis is an alarming problem among residents of the New Valley Governorate. Thus, reducing the prevalence in humans and animals in the region of study may include restriction of the marketing the raw milk and enhancing public health awareness.

Camel trypanosomosis (surra), caused by Trypanosoma evansi , is a life-threatening disease with negative impacts on health, production, and working efficiency of camels in different camel-rearing areas of the world, including Ethiopia. A cross-sectional study was carried out from November 2016 to May 2017 to determine the prevalence of camel trypanosomosis (surra) and assess the associated potential risk factors in Dubti and Asayita districts of Afar region, Ethiopia. Blood samples were collected from 200 camels. Wet film and Giemsa-stained blood smears were used for the detection of trypanosomes. Out of 200 examined, 9(4.5%) were positive for Trypanosoma evansi. The higher prevalence of the disease was observed in Dubti (6.97%) than in Asayita (2.63%) districts. Highest infection was observed in the age group >4 years old camels (7.47%), followed by <4 years old camels (1.07%). Previously aborted camels were found at higher risk (P=0.03; OR = 5.11, 95% CI = 1.174–22.317) than camels without an abortion history. There was no statistically significant difference in between body condition categories and herd size of camels with the occurrence of the disease (X2 = 3.839; P=0.147 and X2 = 0.718; P=0.698), respectively. The result of the current study revealed that camel trypanosomosis is substantially prevalent in the study area, indicating the need for designing control and prevention strategies.

AbstractA cross-sectional study was carried out to determine the seroprevalence of Toxoplasma gondii and associated risk factors in pigs in the largest pork-producing region in Cuba. Serum samples from 420 pigs, including 210 sows and 210 post-weaning pigs, were tested for antibodies against T. gondii using a commercial indirect enzyme-linked immunosorbent assay. Anti-T. gondii antibodies were detected in 56 animals (13.3%, 95% CI: 10.1–16.6). A generalized estimating equations model revealed that the risk factors associated with higher seropositivity in pigs were altitude (higher in farm’s location < 250 m above sea level (masl) versus ≥ 250 masl) and age (higher in sows compared to post-weaning pigs). The results indicated that this protozoan parasite is widely distributed on pig farms in the study area, which is a public health concern since the consumption of raw or undercooked pork meat products containing tissue cysts is considered one of the main routes of T. gondii transmission worldwide. Control measures should be implemented to reduce the risk of exposure to T. gondii in pigs in Cuba.

ObjectivesThe study aimed to provide an association between dysmenorrhoea and academic performance among university students in Ethiopia. Further, the study attempts to determine the prevalence and associated risk factors of dysmenorrhoea.Design and methodInstitution-based cross-sectional study was conducted from 1 April to 28 April 2019. A semistructured and pretested self-administered questionnaire was used to collect data. Binary logistic regression analysis and one-way analysis of variance were performed to model dysmenorrhoea and academic performance, respectively.Setting and participantsEthiopia (2019: n=647 female university students).OutcomesThe primary outcome is dysmenorrhoea, which has been defined as painful menses that prevents normal activity and requires medication. The self-reported cumulative grade point average of students was used as a proxy measure of academic performance, which is the secondary outcome.ResultsThe prevalence of dysmenorrhoea was 317 (51.5%). The educational status of father (adjusted OR (AOR) (95% CI) 2.64 (1.04 to 6.66)), chocolate consumption (AOR (95% CI) 3.39 (95% 1.28 to 8.93)), daily breakfast intake (<5 days/week) (AOR (95% CI) 0.63 (0.42 to 0.95)), irregular menstrual cycle AOR (95% CI) 2.34 (1.55 to 3.54)) and positive family history of dysmenorrhoea AOR (95% CI) 3.29 (2.25 to 4.81)) had statistically significant association with dysmenorrhoea. There was no statistically significant difference in academic performance among students with and without dysmenorrhoea (F (3611)=1.276, p=0.28)).ConclusionsDysmenorrhoea was a common health problem among graduating University students. However, it has no statistically significant impact on academic performance. Reproductive health officers should educate and undermine the negative academic consequences of dysmenorrhoea to reduce the physical and psychological stress that happens to females and their families.

A cross-sectional study was carried out from November 2015 to march 2016 on bovine fasciolosis, to assess the abattoir based prevalence, predominant species of bovine fasciolosis and associated risk factors of the disease in cattle slaughtered in Halaba municipal abattoir. A total of 384 cattle were examined using post mortem examination. Infection rates were (3.64%), 2.34%, 2.08%, and 1.82 % F. gigantic, F. hepatica, mixed and immature respectively with the overall prevalence of 9.88 % (38). F. gigantic was found to be the most prevalent species in cattle of the study area. Multivariable logistic regression analysis showed that the risk of fasciola infection was significantly higher in poor body condition animals than in medium and good body condition animals (p < 0.05). However, in terms of age, sex and breed, no statistically significant difference was found between infected animals (p > 0.05).The present study showed that bovine fasciolosis is one of the important pathogens in cattle in the study area and warrants appropriate disease prevention and control measures and further epidemiological investigations to determine the different agro ecological risk factors on the occurrence of the disease.

Contagious bovine pleuropneumonia (CBPP) is an important infectious disease of respiratory system of cattle, caused by Mycoplasma mycoides subspecies mycoides. A cross sectional study was conducted in Lahore, Kasur and Jhang districts of Punjab to determine the prevalence of CBPP. A total of 560 serum samples were examined for the specific antibodies against M. mycoides subspecies mycoides, using a sandwich enzyme-linked immunosorbent assay. Associated risk factors that were evaluated include age, gender and breed. In this study, the overall seroprevalence was 8.75%. The seroprevalence of CBPP in Lahore, Kasur and Jhang were 8.26, 8.20 and 10.06%, respectively, but no significance difference (P less than 0.05) was observed. Among the assessed potential predisposing factors, gender and breed were not significantly associated with the serological status of the animal (P greater than 0.05), in which the age affected significantly the positivity to CBPP (P less than 0.05). The highest seropositivity was observed in animals of more than 7 years of age (32.08%) followed by in 4-7 years of age (8.16%) and lowest in animals of less than 4 years old (0.79%). This study confirms the presence of CBPP in the state which could be a threat to livestock export market and warrants the implementation of control measures to mitigate the economic losses associated with the disease.

SUMMARYA cross-sectional study was conducted from June 2013 to August 2015 to determine the seroprevalence and possible risk factors for humanToxoplasma gondiiinfection in Korean, Manchu, Mongol and Han ethnic groups in eastern and northeastern China. A total of 1842 serum samples, including Han (n= 802), Korean (n= 520), Manchu (n= 303) and Mongol (n= 217) groups, were analysed using enzyme-linked immunoassays to detect IgG and IgMT. gondiiantibodies. The overallT. gondiiIgG and IgM seroprevalences were 13·79% and 1·25%, respectively. Of these groups, Mongol ethnicity had the highestT. gondiiseroprevalence (20·74%, 45/217), followed by Korean ethnicity (16·54%, 86/520), Manchu ethnicity (13·86%, 42/303) and Han ethnicity (11·35%, 98/802). Multiple analysis showed that the consumption of raw vegetables and fruits, the consumption of raw/undercooked meat and the source of drinking water were significantly associated withT. gondiiinfection in the Han group. Likewise, having a cat at home was identified as being associated withT. gondiiinfection in the Korean, Manchu and Mongol groups. Moreover, the consumption of raw/undercooked meat was identified as another predictor ofT. gondiiseropositivity in the Mongol group. The results of this survey indicate thatT. gondiiinfection is prevalent in Korean, Manchu, Mongol and Han ethnic groups in the study region. Therefore, it is essential to implement integrated strategies with efficient management measures to prevent and controlT. gondiiinfection in this region of China. Moreover, this is the first report ofT. gondiiinfection in Korean, Manchu, and Mongol ethnic groups in eastern and northeastern China.

Background and Objectives: Delirium is one of the most important neuro-psychiatric disorders in Consultation liaison psychiatry. There is a dearth of studies in this subject in Nepalese context. The objective of this study was to find out the demographic profile, source of referral, reason for referral and possible risk factors for delirium and association between risk factors and subtypes of delirium.Material and Methods: This is a descriptive cross-sectional study carried out in a tertiary care center over a period of six months. Delirium was diagnosed by psychiatrist based on International Classification of Disease, 10th revision, Diagnostic Criteria for Research (ICD-10 DCR) and was classified into subtypes using the Liptzin and Levkoff criteria. Data analysis was done using SPSS version 16 and chi- square test was applied to find the association between risk factors and subtypes of delirium.Results: A total of 52 cases of delirium were included in the study. Majority of cases were aged 65 years and above with male preponderance. The most common cause for referral was disturbed behavior and disorientation. Hyperactive delirium was the most common subtype of delirium. Most of the referred cases of delirium were from Medical ward and Intensive Care Unit/Critical Care Unit (ICU/CCU). Infection / Inflammation, Drug/alcohol intoxication or withdrawal and those with multiple etiologies were the most common possible causes of delirium. There was no significant difference in terms of associated risk factors between the clinical subtype (p = 0.8023).Conclusion: The presence of delirium warrants prompt intervention to identify and treat the underlying causes and consultation liaison psychiatric services should be enhanced to achieve this goal.Janaki Medical College Journal of Medical Sciences (2017) Vol. 5(2): 19-26

Abstract Background To estimate the prevalence of strabismus and associated risk factors among grade one school children in Lhasa, Tibet, China. Methods The Lhasa Childhood Eye Study (LCES) was a cross-sectional, school-based childhood study conducted in Grade one students from primary schools in Lhasa, Tibet, China. Comprehensive ophthalmic examinations and basic systemic examinations were evaluated. A questionnaire survey containing information about children, as well as parents’ information, was sent to the corresponding parents of eligible children. The prevalence of strabismus and its 95% confidence interval was estimated. Univariate and multivariate logistic regression analyses were conducted to determine the associated risk factors. Results A total of 1942 eligible grade one students were enrolled, of which 1856 participants completed all examinations. The average age was 6.83 ± 0.46 years, 53% of participants were boys and 1762 were the Tibetan Minority. Over all, the prevalence of strabismus was 68/1856 (3.7%) (95%CI: 2.81,4.52), with no difference between the ages, genders, ethnicities and body mass index, while tilting one’s head when writing may be a risk factor for strabismus (P = 0.004). Strabismus students had mean best corrected visual acuity of 0.16 ± 0.28(LogMAR), over 50% patients with esotropia were hyperopic, and participants who had stereopsis impairments showed a significant difference between esotropia and exotropia (P = 0.026). Conclusions The prevalence of strabismus in LCES was 3.7%, which is higher than previous reports from Chinese childhood epidemiology studies. Strabismus is a common contributing factor to amblyopia. Tilting one’s head when writing may be a risk factor. Esotropia is more likely to affect stereopsis and be associated with the refractive state of hyperopia. Trial registration The study has finished the clinical registration on Chinese Clinical Trial Registry. (http://www.chictr.org.cn, ChiCTR1900026693).

Objective: To assess the level of anxiety among doctors during COVID-19 pandemic and the associated risk factors. Methods: This cross-sectional study was conducted from 30th April to 16th May, 2020 in Karachi, Pakistan. The data was collected via an online web-based questionnaire. Questionnaire was used to assess anxiety level using GAD-7 scale among health-care professionals and the risk factors playing role in it. Results: One hundred and fifty-one doctors participated in our study. Out of these 151 participants, 69 (45.7%) had mild, 22 (14.6%) had moderate, and 5 (3.3%) had severe symptoms of anxiety, whereas the remaining 55 (36.4%) had no anxiety according to GAD-7 scale. The median [interquartile range (IQR)] GAD-7 scale scores are 6.0 [3.00-9.00]. Females showed more severe degrees of measurement of anxiety symptoms than males. Doctors dealing with COVID-19 patients showed higher level of anxiety as compared to the doctors who were not dealing with COVID-19 patients, having a significant difference (U = 9.697, p = 0.008). One hundred and forty-one (93.4%) participants were concerned about being exposed to COVID-19 at work and 112 (74.2 %) thought they have inadequate protective equipment for safety. Conclusions: During COVID-19 pandemic, doctors exhibited different grades of anxiety. In order for healthcare workers to perform to the best of their capability, certain guidelines and interventions are needed. doi: https://doi.org/10.12669/pjms.36.6.3113 How to cite this:Hasan SR, Hamid Z, Jawaid MT, Ali RK.
