Bovine respiratory disease (BRD) is a complex, multifactorial syndrome and one of the major welfare and economical concerns for the cattle industry. This 1-year cross-sectional study was aimed at documenting the prevalence of BRD-related pathogens and clinical signs before and after a long journey and at identifying possible predisposition factors. Male Limousine beef steers (n = 169) traveling from France to Italy were health checked and sampled with Deep Nasopharyngeal Swabs (DNS) at loading (T0) and 4 days after arrival (T1). Real-time quantitative PCR was used to quantify the presence of bovine viral diarrhea virus (BVDV), bovine respiratory syncytial virus (BRSV), bovine alphaherpesvirus 1 (BoHV-1), bovine coronavirus (BCoV), bovine adenovirus (BAdV), bovine parainfluenza virus 3 (BPIV-3), Histophilus somni, Mannheimia haemolytica, Mycoplasma bovis, and Pasteurella multocida. Weather conditions at departure and arrival were recorded, and the travel conditions were taken from the travel documentation. At T0, even if no animals displayed clinical signs, some of them were already positive for one or more pathogens. At T1, the number of animals displaying clinical signs and positive for BCoV, BAdV, BRSV, H. somni, M. haemolytica, M. bovis, and P. multocida increased dramatically (p < 0.001). Transport also significantly increased co-infection passing from 16.0% at T0 to 82.8% at T1 (p < 0.001). An extra stop during the journey seemed to favor BRSV, M. haemolytica, and P. multocida (p < 0.05). Weather conditions, in particular sudden climate changes from departure to arrival and daily temperature variance, were found to be predisposing factors for many of the pathogens. The farm of arrival also played a role for BRSV, BAdV, and H. somni (p < 0.05). BCoV increased dramatically, but no associations were found confirming that it spreads easily during transport phases. Our findings increased our understanding of factors increasing the likelihood of BRD-related pathogens shedding and can be useful to minimize the incidence of BRD and to implement animal transport regulations.

A broad, cross-sectional study of beef cattle at entry into Canadian feedlots investigated the prevalence and epidemiology of antimicrobial resistance (AMR) in Mannheimia haemolytica, Pasteurella multocida, Histophilus somni, and Mycoplasma bovis, bacterial members of the bovine respiratory disease (BRD) complex. Upon feedlot arrival and before antimicrobials were administered at the feedlot, deep nasopharyngeal swabs were collected from 2,824 feedlot cattle in southern and central Alberta, Canada. Data on the date of feedlot arrival, cattle type (beef, dairy), sex (heifer, bull, steer), weight (kg), age class (calf, yearling), source (ranch direct, auction barn, backgrounding operations), risk of developing BRD (high, low), and weather conditions at arrival (temperature, precipitation, and estimated wind speed) were obtained. Mannheimia haemolytica, P. multocida, and H. somni isolates with multidrug-resistant (MDR) profiles associated with the presence of integrative and conjugative elements were isolated more often from dairy-type than from beef-type cattle. Our results showed that beef-type cattle from backgrounding operations presented higher odds of AMR bacteria as compared to auction-derived calves. Oxytetracycline resistance was the most frequently observed resistance across all Pasteurellaceae species and cattle types. Mycoplasma bovis exhibited high macrolide minimum inhibitory concentrations in both cattle types. Whether these MDR isolates establish and persist within the feedlot environment, requires further evaluation.

Bovine respiratory disease (BRD) is a serious health and economic problem in the beef industry, which is often associated with transportation and caused by different pathogens. The prevalence of bovine herpesvirus type 1 (BoHV-1), bovine adenovirus (BAdV), bovine viral diarrhea virus (BVDV), bovine coronavirus (BCoV), bovine respiratory syncytial virus (BRSV), bovine parainfluenza virus (BPiV), Pasteurella multocida, Mannheimia haemolytica, Histophilus somni, Mycoplasma bovis, in the nasal microbiota of beef steers before and after the same long-distance journey from France to southern Italy was documented. Fifty-six Limousine animals of three different shipments, travelling on three different days from February to April, were included. Prior to shipment (T0) and four days after arrival (T1), two DNS/animal were collected and tested by Real Time quantitative PCR (qPCR). Univariate logistic regression was carried out, considering time and day as fixed factors and the outcome of qPCR for each pathogen as a dependent categorical dichotomous variable (positive/negative, 1/0). The fact that the number of H. somni positive animals were found to be higher in the third shipment than the first and second one, indicating that this pathogen was already present before loading, is relevant. The prevalence of BCoV, BRSV, M. haemolytica, M. bovis, P. multocida was higher at T1 than T0, suggesting that other factors, such as stress and the epidemiological status of the arrival farm, played a role. The tested animals were not treated before and after transport, and our results are in agreement with the current literature, supporting the hypothesis that the prevalence of pathogens related to BRD would increase after travelling, with an increased risk of pathogens shedding.

Background: This article aimed to assessment clinical signs and symptoms, paraclinical tests and histopathological results in children with acute appendicitis.Methods: A cross-sectional study conducted on 100 children with acute appendicitis in an urban hospital in southeast of Iran from January to December 2016. Participants were selected by simple random sampling method. Clinical signs and symptoms, paraclinical tests and histopathological results recorded in checklists. The data were analyzed using SPSS 22.Results: Mean age of the patients was 10.26±3.25, fourthly-eight of patients (58.5%) were males and 34 patients (41.5%) were females. The most frequent clinical signs and symptoms were acute suppurative appendicitis with peri appendicitis (45.83%) and acute suppurative appendicitis (39.58%). The most frequent results in ultrasound reports were Intestinal loop thickness greater than 6 mm without peristalsis (positive report) (46.34%) and Invisible appendix (nega Hesaraki tive report) (13.41%).Conclusions: The results of this study showed that abdominal pain and RLQ tenderness were the most common signs and symptoms and WBC left-shift was the most common laboratory finding. Since the rate of negative appendectomy in this study was consistent with surgical results and other articles, it is concluded that diagnostic accuracy of preoperative appendectomy was acceptable and most children with acute appendicitis underwent appendectomy.

Abstract Background: This study was conducted to investigate the treatment seeking behavior for COVID-19 symptoms among northern Iranian population and its related factors.Methods: This hospital-based cross-sectional study was conducted to investigate the treatment seeking behavior for COVID-19 symptoms and its related factors in 602 confirmed COVID-19 cases for a period of 2 months between March and May 2020 in Guilan at the onset of the corona epidemic in Iran. Results: Professional treatment-seeking was observed in 18.6% of patients and most of patient reported home remedies (50.3%) and self-medication (31.1%) as first reaction to COVID-19 symptoms. The multivariate logistic regression analyses revealed that patients with breathing difficulties symptom and history of respiratory disease had greater odds professional treatment of seeking respectively (adjusted odds ratio (OR) =1.6, P=0.03, (OR) =3.3, P =0.001). Conclusions: Roughly half of symptomatic COVID-19 patient reported home remedies as first treatment-seeking behaviors and only breathing difficulties symptom and past history of respiratory disease were identified as an independent predictor of professional treatment–seeking. However, we found no more professional treatment -seeking behaviors among elderly, diabetic, hypertensive and obese patients, while there were at risk of severe illness and death from COVID-19 infections. Thus, behavior change interventions in population with underling disease (including diabetes, hypertension and obesity) and older age is crucial to improve professional treatment -seeking behaviors.

Commercial poultry production is growing rapidly in Bangladesh to address the increasing demand for poultry meat and eggs. Challenges faced by producers include the occurrence of poultry diseases, which are usually treated or controlled by antimicrobials. A cross-sectional study was conducted on 57 commercial layer and 83 broiler farms in eight subdistricts of the Chattogram district, Bangladesh, to assess antimicrobial usage in relation to clinical signs observed in chicken flocks on these farms. Of the 140 commercial chicken farms, 137 (97.9%) used antimicrobials and 24 different antimicrobial agents were administered. On layer farms, the most commonly used antimicrobials were ciprofloxacin (37.0% of farms, 20/54), amoxicillin (33.3%, 18/54), and tiamulin (31.5%, 17/54), while on broiler farms, colistin (56.6%, 47/83), doxycycline (50.6%, 42/83), and neomycin (38.6%, 32/83) were most commonly administered. Only 15.3% (21/137) of farmers used antimicrobials exclusively for therapeutic purposes, while 84.7% (116/137) of farmers used them prophylactically, administering them either for prophylactic purposes only (22.6% of farmers, 31/137) or in combination with therapeutic purposes (62.1% of farmers, 85/137). About 83.3% (45/54) of layer farmers were selling eggs while antimicrobials were being administered compared to 36.1% (30/83) of the broiler farmers selling broiler chickens while administering antimicrobials. Overall, 75.2% (103/137) of farmers reported clinical signs for which they administered antimicrobials, while 24.8% (34/137) of farmers reported no clinical signs but still administered antimicrobials. Respiratory signs (71.8% of farms with clinical signs, 74/103) were most commonly reported, followed by enteric signs (32.0%, 33/103) and increased mortality (16.5%, 17/103). About 37.2% (51/137) of farmers bought antimicrobials exclusively from feed and chick traders, followed by veterinary medical stores (35.0%, 48/137). Purchasing antimicrobials from feed and chick traders was more common among broiler than layer farmers. It is recommended that commercial poultry farmers should keep records of antimicrobials used with dosage and duration of administration along with indication of use. This would allow farmers and veterinarians to review if antimicrobial usage had the desired effects and to evaluate the appropriate use of antimicrobial agents under an antimicrobial stewardship approach.

Introduction: The clinical evaluation of the three layers of tear film is still poorly described. The purpose of this study is to evaluate the value of aqueous assessment in diagnosing dry eye. Materials and method: Schirmer test with anaesthesia (STA) and tear meniscus height (TMH) measurement were conducted on non-dry eye (NDE) and dry eye (DE) subjects in this cross-sectional study. The NDE and DE subjects were classified using two types of classification; classification 1 and classification 2. Results: 321 subjects with 642 eyes were recruited in the study. STA was significantly correlated with TMH (r = 0.24, p < 0.001) in all 642 eyes. The comparison between nondry and dry eye subjects in STA and TMH were not significantly different (p > 0.05) if the Classification 1 was used to define dry eye. In Classification 2, there were significantly different between NDE (12.5 ± 8.2 mm) and DE (3.4 ± 0.8 mm) subjects in STA (p < 0.001). Similar trend was also depicted in TMH based on the definition of dry eye stated in Classification 2 (NDE = 0.45 ± 0.20 mm, DE = 0.39 ± 0.14 mm; p < 0.05). Conclusion: The value of STA and TMH were lower significantly in dry eye subjects. However, the significant outcomes were only demonstrated if the clinical signs of dryness were used in the definition of dry eye.

Tuberculosis (TB) remains a real public health concern in Africa; thyroid localisation of the disease is a very rare form of extrapulmonary TB. We conducted a descriptive and cross-sectional study on all histologically proved cases of thyroid TB diagnosed in Togo over the last 20 years. Eleven cases of TB of the thyroid were identified, of which nine were in women, with an average age of 29.4 ± 0.2 years. The clinical signs were the presence of a nodule in seven, an abscess in three and a swelling with cutaneous fistulisation in one. Thyroid involvement alone was found in four, associated with pleuropulmonary TB in six and mammary TB in one. Human immunodeficiency virus (HIV) co-infection was present in six. All histopathology results showed inflammatory granulomata with caseous necrosis. The clinical features are often misleading and pose a real diagnostic problem, especially with differentials of simple abscess and cancer.

Background Pneumonia is the leading cause of childhood mortalityin the world. Although WHO develops an algorithm fordiagnosing pneumonia, many clinicians still under or overdiagnosethis disease.Objective To assess associations of cough, tachypnea, fever, andchest indrawing with pneumonia in children.Methods This cross-sectional study was conducted using medicalrecords of children aged less than 5 year old with one or more clinicalsigns of pneumonia such as cough, fever, tachypnea, and chestindrawing in Haji Adam Malik Hospital, Medan from January2009 to December 2011. Pneumonia was diagnosed by pediatricrespirologists based on history-taking, and physical, laboratoryand radiology examinations. Patients with incomplete datawere excluded. Data was analyzed by bivariate and multivariateanalyses.Results Of 420 subjects, the majority were aged 3 to 23 monthsand there were more boys than girls. Clinical signs assessed forwere cough (82.9%), tachypnea (31 %), fever (79.3%), and chestindrawing (40.2%). Age < 24 months (OR 2.563; 95% CI 1.497to 4.387), cough (OR 2.274; 95% CI 1.042 to 4.960), tachypnea(OR 2.249; 95% CI 1.282 to 3.947), and chest indrawing (OR6.993; 95% CI 4.017 to 12.173) were significant predictors forpneumonia.Conclusion Age less than 24 months, cough, tachypnea, andchest indrawing are significantly associated with pneumonia.
