Fattening Pigs

The objective of this study was to estimate the prevalence and identify risk factors associated with the presence ofToxoplasma gondiiin pig-fattening farms from Yucatan, Mexico. A cross-sectional study was conducted with a two-stage sampling. There were 429 pigs sampled from 39 farms randomly selected. Blood samples were collected to obtain DNA and serum. The presence of IgM and IgG antibodies was determined by indirect ELISA. Prevalence was estimated by diagnostic test. Potential risk factors to be included in a marginal logistic regression were tested by chi-square or Fisher. The prevalence of IgM and IgG was 92.5% (397/429) (CI 89.9–95.1%) and 95.8% (411/429) (CI 93.7–97.8%), respectively. Regarding PCR, a prevalence of 50.8% (218/429) (CI 45.9–55.6%) was found. The logistic regression showed an association with herd size and type of feeder (). The risk of a case in farms with ≤400 pigs was 27.9 times higher than in farms with >400 pigs. The manual feeder was a significant protective factor associated with the seropositive againstT. gondii. Results indicate a high circulation ofT. gondiiin pig-fattening farms from Yucatan, finding an increased risk of infection for those farms with less than 400 animals and automatic feeders.

AbstractThis cross-sectional study investigated the characteristics of cervical HPV infection in Changsha area and explored the influence of Candida vaginitis on this infection. From 11 August 2017 to 11 September 2018, 12,628 outpatient participants ranged from 19 to 84 years old were enrolled and analyzed. HPV DNA was amplified and tested by HPV GenoArray Test Kit. The vaginal ecology was detected by microscopic and biochemistry examinations. The diagnosis of Candida vaginitis was based on microscopic examination (spores, and/or hypha) and biochemical testing (galactosidase) for vaginal discharge by experts. Statistical analyses were performed using SAS 9.4. Continuous and categorical variables were analyzed by t-tests and by Chi-square tests, respectively. HPV infection risk factors were analyzed using multivariate logistic regression. Of the total number of participants, 1753 were infected with HPV (13.88%). Females aged ≥ 40 to < 50 years constituted the largest population of HPV-infected females (31.26%). The top 5 HPV subtypes affecting this population of 1753 infected females were the following: HPV-52 (28.01%), HPV-58 (14.83%), CP8304 (11.47%), HPV-53 (10.84%), and HPV-39 (9.64%). Age (OR 1.01; 95% CI 1–1.01; P < 0.05) and alcohol consumption (OR 1.30; 95% CI 1.09–1.56; P < 0.01) were found to be risk factors for HPV infection. However, the presence of Candida in the vaginal flora was found to be a protective factor against HPV infection (OR 0.62; 95% CI 0.48–0.8; P < 0.001). Comparing with our previous study of 2016, we conclude that the subtype distribution of HPV infection is relatively constant in Changsha. Our data suggest a negative correlation between vaginal Candida and HPV, however, more radical HPV management is required in this area for perimenopausal women and those who regularly consume alcohol.

Abstract Background Our objective was the validation of a scale to assess the hygiene hypothesis and the link between hygiene, and asthma among 3 to 5 years old Lebanese children in preschool.Methods Between November 2018 and March 2019, this cross-sectional study was carried out, enrolled 515 preschool children’ asthma and potential risk factors, including hygiene, were assessed using a standardized questionnaire. A specific hygiene hypothesis related scale was generated and validated for this purpose.Results Items related to the hygiene hypothesis scale have led to a convergence over a nine factors solution, having over than 1 Eigenvalue, which explains the variance total of 65.86%. Cronbach’s alpha values corresponding to the hygiene hypothesis related scale (0.696) was deemed acceptable. The backward logistic regression, taking as dependent variable the asthma’s presence or absence in child, showed that living in prairie (ORa=2.42), playing outside (ORa=2.80), having respiratory problems (ORa=4.18), attending a kindergarten (ORa=2.76), and having a sister with seasonal allergy (ORa=6.86) had significant association with increased odds of occurrence of children’s asthma. The hygiene hypothesis related score was not found to be associated with increased asthma odds (p=0.663).Conclusion Current findings suggested that home cleaning and personal cleanliness were not correlated with asthma in preschool children. Future studies will require more in-depth analyses of microbial exposure, allowing proper identification of unequivocal species and functional characteristics.

Hookworms infection remains as an important parasitic infections affecting animal and human health worldwide. However, information on the prevalence and the risk factors of hookworm infection on dogs in Indonesia is very limited. A cross sectional study to estimate the prevalence and to identify risk factors of hookworms infection on dogs was conducted in rural area with different topography, Sukabumi Regency, Indonesia. A Total of 204 dog stool specimens were examined for hookworm eggs using simple flotation methods. The data of related risk factors namely type of topography area (high and low land), purpose of having dog, dog demography, dog reared management and deworming were collected through dog owners interview’s with completed a questionnaire. Those data were analyzed using the chi-square test (χ2) and logistic regression. The prevalence of hookworm on dogs in Sukabumi was 24.5 % (95% Confidence Interval [CI]=19.1-30.8). This prevalence was associated with topography of the area, the age of dog, and type of dog keeping methods. The prevalence of hookworms was higher in the high land area than low land area (OR=5.935, 95% CI=2.764-12.744 ). Logistic regression identified pupies as a high risk group to hookworms infection (OR= 2.041, 95%CI=1.035-4.055). The dog which kept in the cage/tied had higher risk than free roaming dog (OR=3.66, 95%CI=1.479-9.091).Key words: Dog, hookworms, prevalence, risk factors, Sukabumi.

Bovine tuberculosis (bTB) is a disease of zoonotic importance as well as high priority all over the world. Risk factors for bovine tuberculosis in cattle are not well investigated in Bangladesh. Therefore, the objective of this study was to identify the associated risk factors for bTB along with determination of prevalence in cattle of Mymensingh Sadar. A cross-sectional study was carried out to elucidate on 101 cattle from 56 households during January to May 2012. The direct interview using a questionnaire and physical examination of cattle was performed to collect farm and animal level data. Besides data collection, blood samples were collected from study cattle and subjected to immunochromatographic assay (ICGA) by using Anigen Rapid Bovine TB Ab test kit for the diagnosis of bTB. Risk factors analysis was done using bivariable followed by multiple logistic regression with stepwise backward elimination method. The results of the study revealed an overall tuberculosis prevalence of 5.9%. Multiple logistic regression analysis revealed significant association of bovine tuberculosis with herd size (more than 4) (Odds Ratio, OR = 5.9, p = 0.03) and history of coughing (OR = 8.9, p = 0.005). The effect of herd size (more than 4) could be minimized by maintaining the cattle in a herd with adequate floor space and better ventilation facilities as it would not be practicable to keep the herd size minimum. Further study should be done to find out more associated risk factors for the occurrence of bTB.DOI: http://dx.doi.org/10.3329/bjvm.v12i2.21283 Bangl. J. Vet. Med. (2014). 12 (2): 179-183

Objective The objective of this study was to analyse the prevalence and the clinical features of headache as a presenting symptom of glioma. Methods We interviewed 527 consecutive adult patients with histologically confirmed glioma, admitted to the Regina Elena National Cancer Institute between 2010 and 2015. We defined four headache phenotypes: Tension-type-like headache (TTH), migraine-like headache, worsening of a pre-existing headache (WPH) and classic brain tumour headache (BTH). Logistic regression analysis was carried out to investigate potential risk factors for headache at presentation of glioma. Results 12.5% (n = 66) of patients with glioma indicated headache as a presenting symptom of their disease. Of these, 31 patients (47%) had TTH, while BTH and WPH were reported by 28 (42%) and seven (11%) patients, respectively. We did not find any case of migraine-like headache. Infratentorial ( p = 0.038) and right-sided tumours ( p = 0.013) were more frequently associated with the presence of headache at onset. Patients with TTH were older than patients with BTH and WPH ( p = 0.035). BTH was less frequently associated with other neurological signs ( p < 0.0001). The multivariate logistic regression analysis showed the localization of the brain tumour in the left hemisphere to be a protective factor for the development of headache. Conclusions Our study includes a very large series of patients with glioma, providing a description of headache phenotype at first presentation of disease and investigating possible factors that may influence the clinical features of headache.

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.

Background<br />Cysticercosis is an infectious disease caused by the larval form of Taenia solium (cysticercus cellulosae) and has been ranked as the most important food-borne parasite of humans in terms of public health, socioeconomic and trade impact. Cysticercosis is still a health problem in Papua and is inseparable from socio-cultural factors, hygiene and environmental sanitation. The aim of this study was to investigate the seroprevalence of cysticercosis and the risk factors that contribute to cysticercosis.<br /><br />Methods<br />A cross-sectional study was conducted in March-November 2016 involving 800 subjects. Demographic data and risk factors were collected using questionnaires. Cysticercosis serological examination was performed by means of the magnetic microsphere bead immunoassay technique coupled with rT24H recombinant protein to detect serum rT24H cysticercosis specific antibodies. The data obtained were analyzed by bivariate test (chi-square) and logistic regression.<br /><br />Results<br />Cysticercosis seroprevalence in Papua was 3.6% (284/7 874). The logistic regression analysis found that the risk factors playing the role of predictor were cooking pork with hot stones [OR=3.06; 95%CI: 2.19-4.28; p=0.000], nail hygiene [OR=2.05; 95%CI: 1.57-2.67; p=0.000], consumption of raw vegetables or salads [OR=0.52; 95%CI: 0.30-0.91; p=0.022], use of river water for washing foods [OR= 1.92; 95%CI: 1.39-2.64; p=0.000].<br /><br />Conclusions<br />Cooking pork with hot stones was the main risk factor of cysticercosis. Suspected cases of T. solium in pigs should be confirmed by molecular methods. Both taeniasis and human cysticercosis should be notifiable and surveillance in animals should be improved.

Background. While pathological gambling, or gambling disorder, is an established diagnosis, a link to other potential behavioural addictions has been suggested. The present study aimed to investigate whether signs of problem gaming and problematic internet use are related to problem gambling in the general population, while including other potential risk factors. Methods. A cross-sectional study design, using an electronical questionnaire, administered through a marketing survey company for relative representativeness with respect to age and gender. Potential correlates of problem gambling were measured in binary analyses, and significant associations were entered in a logistic regression analysis controlling them for one another. Problem gambling, gaming, and internet use were measured through established screening instruments (the CLiP, the GAS, and the PRIUSS). Results. Statistically significant associations were found between problem gambling and both problem gaming and problematic internet use, as well as with male gender. In logistic regression, problem gaming, problematic internet use, and male gender remained associated with problem gambling. Conclusion. After controlling for potential demographic risk factors, problem gaming and problematic internet use may be related to problem gambling, suggesting that these constructs may interact or may share similar risk factors. More research is needed to clarify factors mediating the links between these conditions.

AbstrakPreeklampsia dapat menimbulkan berbagai komplikasi yang membahayakan bagi ibu dan janin, sehingga dapat menimbulkan kematian.  Beberapa faktor risiko seperti usia yang ekstrem (<20 &>35 tahun) dan nuliparitas. Keduanya merupakan faktor risiko yang tidak dapat dimodifikasi. Tujuan  penelitian ini adalah menentukan hubungan usia dan paritas dengan kejadian preeklampsia berat. Telah dilakukan penelitian di Bagian Rekam Medis Rumah Sakit Achmad Mochtar Bukittinggi terhadap data semua pasien rawat inap obstetri dan ginekologi tahun 2012 – 2013.  Penelitian menggunakan metode analitik dengan desain cross sectional study. Analisis penelitian menggunakan ratio prevalence dan chi-square test dengan derajat kepercayaan 95%. Penelitian ini menemukan 162 kasus (4,99%) preeklampsia berat. Proporsi kasus terbesar ditemukan pada kelompok usia ekstrem (9,90%) dan kelompok multiparitas (8,68%). Analisis ratio prevalence menyimpulkan bahwa usia ekstrem merupakan faktor risiko preeklampsia berat (RP= 1,476; CI= 1,094 – 1,922), dan nuliparitas belum dapat ditentukan apakah merupakan faktor risiko atau faktor protektif (RP= 0,765; CI= 0,565 – 1,034). Berdasarkan analisis dengan chi-square test, disimpulkan bahwa terdapat hubungan yang bermakna antara usia dengan preeklampsia berat (p= 0,014<0,05) dan tidak terdapat hubungan yang bermakna antara paritas dengan preeklampsia berat (p= 0,096>0,05).Kata kunci: preeklampsia, faktor risiko, usia, paritas AbstractPreeclampsia can cause the complication that endanger maternal and fetal, until death. There are many risk factors like extreme age (<20 & >35 years) and nuliparity that can not modify. The objective of this study was to  determine the relationship of maternal age and parity to the incidence of severe preeclampsia.  The research conducted at Medical Record Division of Achmad Mochtar Hospital Bukittinggi about data of all hospitalized patients of obstetrics and gynecology on 2012 – 2013. This research used the analytical method with cross sectional study. Analysis of this research used ratio prevalence and chi-square test with degree of confidence 95%. This research  found 162 case (4.99%) severe preeclampsia. The highest proportion of this case was the extreme age groups (9.90%) and multiparity group (8.68%). Analysis with the ratio prevalence concluded that extreme age is a risk factor for severe preeclampsia (RP=1.476; CI= 1.094 – 1.922) and nuliparity can not determined wheather a risk factor or protective factor (RP= 0.765; CI= 0.565 – 1.034). Analysis with chi-square test concluded that there is a significant relationship between age with severe preeclampsia (p= 0.014<0.05) and there is no significant relationship between parity with severe preeclampsia (p= 0.096>0.05).Keywords: preeclampsia, risk factors, age, parity
