Abstract Background Outbreaks of infectious arthritis in young lambs associated with Streptococcus dysgalactiae subspecies dysgalactiae (SDSD) lead to reduced animal welfare, increased use of antibiotics and economic losses for sheep farmers. Understanding risk factors is essential when developing strategies to prevent such outbreaks. This questionnaire-based cross-sectional study classified sheep flocks of respondents as cases or controls. Flock-level risk factors for outbreaks of infectious arthritis were assessed using a multivariable logistic regression model. Results Eighty-four of 1498 respondents (5.6%) experienced an outbreak of infectious arthritis in their flock in 2018, the year of study. Factors associated with a higher risk of outbreak were larger flock size (OR 1.3, 95% CI 1.1–1.4, per 100 lambs), plastic mesh flooring in the lambing pen (OR 3.0, 95% CI 1.7–5.3) and a lambing percentage greater than 200 (OR 2.0, 95% CI 1.1–3.5). Flocks where farmers observed infections around the ear tags of lambs also had an increased risk of outbreak (OR 2.6, 95% CI 1.6–4.3). Conclusions The risk factors identified in this study are characteristic of modern and intensively managed sheep farms in Norway. A distinguishing feature of Norwegian sheep farming is winter housing and indoor lambing. One might expect that this in itself is a risk factor because of high stocking densities during lambing. However, outbreaks of infectious arthritis in young lambs are reported by the industry to be a more recent phenomenon. The current study indicates that intensification of indoor management systems with larger flocks and higher production per ewe may predispose to outbreaks. The results provide a basis for further studies on transmission dynamics of SDSD in sheep flocks with indoor lambing.

Background: Exodontia is one of the most frequently carried out procedures by a dental surgeon, mostly on an outpatient department basis. The reasons for performing exodontia include non-restorable teeth, periodontal disease, dental trauma, impacted tooth, orthodontic treatment and toothache. Complications in dental extraction are a commonly encountered problem in dental clinics. This knowledge can help dental surgeons make extractions less invasive, traumatic and complicated, enabling quicker recovery of the socket. The aim of this study was to recognize types, frequency and risk factors for complications after exodontia. Methods: This cross-sectional study enrolled patients who had exodontia done from July- September 2019, visiting OPD of the Oral surgery department of Altamash Institute of Dental Medicine, Karachi. Risk factors included demographic data, general health, past medical and dental history. Spearman’s correlation test was used to establish any relationship of variables with complications. Results: The study patients (126) included 72 females (mean age 39.1±13.39) and 54 males (mean age 41.1±14.93). The overall complications rate was found to be 7.1%, mainly arising from maxillary and mandibular third molars. The most common complications encountered were Hemorrhage, Pain, and Trismus. Increasing age and specific teeth extracted were associated with an increased risk for complications. However, post-operative complications which were encountered most of them were minor and handled on an outpatient department basis. Conclusion: Frequency and risk factors for complications after exodontia were found low3 (37.5%). While age and teeth extracted cannot be directly altered, these factors maybe indirectly modified, resulting in a potential decrease of postoperative complications.

Background: Contagious caprine pleuropneumonia (CCPP), caused by Mycoplasma capricolum subsp. Capripneumoniae (Mccp), is one of the most important goat diseases causing high morbidity and mortality, these results in heavy economic losses to countries like Somalia, which is a country affected the civil war of the 1990s. Objective: Generally, the disease presence has been reported in the country. However, there is no quantitative data on the prevalence and distribution of the disease has been scientifically reported in the country. Methods: A cross-sectional study was conducted from September 2019 to June 2020 in three villages of Afgoye district of Somalia to assess the seroprevalence and identify the associated risk factors for the occurrence of the CCPP. The risk factors considered included sex, age, and locations. Results: A total of 100 blood samples were collected and evaluated by Capri-Latex Agglutination Test (Capri-LAT). A total of 49/100 (49%, CI 95%: (38.86%-59.2%) goats were seropositive for anti-CCPP antibody. The epidemiological risk factors considered, sex, age and locations, were not significantly associated with the CCPP sero prevalence (p>0.05). However, the sero positivity was slightly higher in female (51%, 95% CI: 39.8-62.6), >3 years old goats (86.3%, 95% CI: 48.9-87.4) and Markazka village (56%, 95% CI: 41.3-70.0) compared to male (40%, 95% CI: 19.1-63.9), 1-3 years old (57.5%, 95% CI: 40.9- 73.0), and Shareeco (43.8%, 95% CI: 19.8-70.1) and Siinka (41.2%, 95% CI: 24.7-59.3) villages, respectively. Conclusion: The present study indicates the prevalence of CCPP in the studies areas and this requires practicable measures to be put in place towards the control 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.

Aims: Alcoholism is known to be associated with increased risk of fracture. This study aimed to study bone turnover following alcohol detoxification and to investigate lifestyle factors for low bone density that might coexist with alcohol dependency, which might be amenable to modification. Method: Pre-menopausal female participants were recruited from an alcohol-use dependency unit to a cross-sectional study. A lifestyle questionnaire, including alcohol history, smoking, physical activity, dietary calcium intake, falls, and fracture history was completed. Quantitative heel ultrasonography was performed and broadband ultrasound attenuation (BUA), speed of sound (SOS), t score, and z score were recorded. Blood was taken for bone-turnover markers at baseline and day 5 following admission for alcohol withdrawal.Results: The mean age (SD) of alcohol dependent participants was 41.6 (8.3) years, with participants reporting high levels of current cigarette smoking, physical inactivity, and falls. BUA, SOS, t scores, and z scores were lower than the age-matched reference range in alcohol-dependent participants. Levels of type 1 procollagen (P1NP) increased significantly after five days (p < .001). Conclusions: Alcohol-dependent, pre-menopausal individuals have multiple risk factors for fracture, beyond alcohol excess. These should be addressed and targeted as modification may reduce fracture risk, especially given the apparent recovery of bone turnover on the withdrawal of alcohol.

Epizootic lymphangitis caused by Histoplasma capsulatum variety farciminosum is a debilitating disease incurring considerable economic losses and affecting the welfare of carthorses. Understanding of its epidemiology is important for devising effective prevention and control measures. A cross-sectional study was conducted on 4,162 carthorses in 17 towns in Ethiopia between October 2018 and June 2019. Clinical and microscopic examinations, fungal culturing, and polymerase chain reaction were used to undertake this study. The overall prevalence of epizootic lymphangitis was 16.67% (95% CI: 15.55–17.84) in carthorses. Epizootic lymphangitis was detected in carthorses found in 16 of the 17 towns included in the study. The highest prevalence was recorded at Kombolcha Town (33.33; 95% CI: 27.54–39.52) whereas the lowest was recorded at Debre Birhan Town (0.00; 95% CI: 0.00–1.27). The results of univariable firth logistic regression analysis showed that the difference between the prevalence of Kombolcha and the prevalences of all the other towns except Holota and Shashemene were statistically significant. Statistically significantly lower prevalence was observed in other towns. Classification of the cases into different clinical forms showed that 87.18, 4.33, and 0.58% were cutaneous, ocular, and respiratory forms respectively, while the remaining 7.93% (55/694; 95% CI: 6.03–10.19) were classified as mixed form. In terms of the severity of the disease, 28.67, 60.52, and 0.81% were mild, moderate, and severe cases, respectively. The majority of the lesions (43.95%) were observed in the skin followed by forelimbs (14.55%) and neck region (14.27%). Higher mean annual temperature, lower annual rainfall, and higher humidity of the study towns were statistically significantly associated with an increased risk of epizootic lymphangitis. In conclusion this study revealed widespread occurrence of epizootic lymphangitis in carthorses yet a heterogeneous prevalence between towns. The veterinary and livestock authorities should take this into account while devising disease control.

Abstract Introduction 98% of the 2.6 million stillbirths per annum occur in low and middle income countries. However, understanding of risk factors for stillbirth in these settings is incomplete, hampering efforts to develop effective strategies to prevent deaths. Methods A cross-sectional study of eligible women on the postnatal ward at Mpilo Hospital, Zimbabwe was undertaken between 01/08/2018 and 31/03/2019 (n = 1779). Data were collected from birth records for maternal characteristics, obstetric and past medical history, antenatal care and pregnancy outcome. A directed acyclic graph was constructed with multivariable logistic regression performed to fit the corresponding model specification to data comprising singleton pregnancies, excluding neonatal deaths (n = 1734), using multiple imputation for missing data. Where possible, findings were validated against all women with births recorded in the hospital birth register (n = 1847). Results Risk factors for stillbirth included: previous stillbirth (29/1691 (2%) of livebirths and 39/43 (91%) of stillbirths, adjusted Odds Ratio (aOR) 2628.9, 95% CI 342.8 to 20,163.0), antenatal care (aOR 44.49 no antenatal care vs. > 4 antenatal care visits, 95% CI 6.80 to 291.19), maternal medical complications (aOR 7.33, 95% CI 1.99 to 26.92) and season of birth (Cold season vs. Mild aOR 14.29, 95% CI 3.09 to 66.08; Hot season vs. Mild aOR 3.39, 95% CI 0.86 to 13.27). Women who had recurrent stillbirth had a lower educational and health status (18.2% had no education vs. 10.0%) and were less likely to receive antenatal care (20.5% had no antenatal care vs. 6.6%) than women without recurrent stillbirth. Conclusion The increased risk in women who have a history of stillbirth is a novel finding in Low and Middle Income Countries (LMICs) and is in agreement with findings from High Income Countries (HICs), although the estimated effect size is much greater (OR in HICs ~ 5). Developing antenatal care for this group of women offers an important opportunity for stillbirth prevention.

Infectious bronchitis is an important virial disease affecting poultry production which causes significant economic losses. A cross-sectional study was carried out from November 2019 to January 2020. To estimating the prevalence of infectious bronchitis and determines the risk factors. A total 420 poultry were by a simple random sampling procedure. Data was analyzed using STATA version 11. Chi square test and logistic regression analysis were used to determine the association between prevalence of infectious bronchitis and potential risk factors. From the total 420 poultry examined for infectious bronchitis were found positive. There was significance difference between the risk factors and bronchitis infections. More infectious bronchitis infected poultry were found in kindokoy 90.4%, odd ratio: 0.3 Confidence Interval :0.1-0.7, p = 0.00 than humbo, sodozuri and damotgale. There was high prevalence of infectious bronchitis in gerater than 6 months than less than 3 months and between 3 and 6-month age of poultry. The presence of infectious bronchitis in poultry production might entail morbidity and mortality. Therefore, further detailed molecular epidemiological studies are warranted. Good hygienic and husbandry practices are essential to limit the spread of infection

People working in health care services have an increased risk of being infected with methicillin-resistant Staphylococcus aureus (MRSA), though little is known about the prevalence in rehabilitation centers. This cross-sectional study investigated the MRSA prevalence in employees from different rehabilitation centers and aimed to identify risk factors for MRSA transmission. We invited all staff (i.e., with and without patient contact from 22 participating rehabilitation centers; n = 2499) to participate. Study participation included a questionnaire on personal characteristics, lifestyle, personal and occupational risk factors for MRSA and nasal swabs taken by the study team. In total, 1005 persons participated in the study (response: 40.2%). Only four participants carried MRSA (0.40 (95% CI 0.00–1.00) per 100). MRSA carriage did not seem to be occupationally related, as it was found in different occupations with and without direct contact with MRSA patients, as well as in different clinics with different indications and patient clientele. We could not find a clear association between MRSA carriage and potential risk factors due to the low number of cases found. Genotyping revealed the spa types t032 (Barnim epidemic strain) and t1223. Our results suggest a low point prevalence of nasal MRSA colonization in a non-outbreak setting in employees from rehabilitation centers.

Background: Acute coronary syndrome (ACS) is one of the leading causes of mortality worldwide and is characterized by unstable angina or acute myocardial infarction. The aim of this study is to evaluate the clinical characteristics of patients who died of ACS. Methods: In this cross-sectional study, 1000 patients presenting ACS were included. Data and records of these patients were evaluated for parameters such as; deceased status, age, gender, diagnosis, ECG, common complaints, associated risk factors, Killip class, pulse, blood pressure, geographic setup (urban or rural), complications and season in which the disease was presented. Statistical analysis was performed on the data obtained using SPSS-win software. Results: The mortality rate among ACS patients in our study was 7.1%. Of these patients, AMI was the most prevalent diagnosis and chest pain was the most common complaint. Furthermore, low blood pressure, advanced age, increased pulse rate and fall/winter season were associated with the increased risk of mortality. ST deviation was the most seen ECG finding and most of the mortalities were within the 24 hours of admission. Conclusion: Our study reports risk factors associated with mortality in ACS patients. Advanced and timely therapeutic measurements are likely to reduce the incidence of mortality in these patients.

Abstract Background Rectal douching (RD) is widely practiced by men who have sex with men (MSM), and is associated with increased risk of HIV infection. However, the mechanism of how RD increases the risk of HIV infection is not well understood, and there is limited data on RD behavior in MSM practicing anal sex in China. We examine the purpose of RD, its timing in relation to anal sex, the types of RD products used, and risky sexual behaviors among MSM reporting anal sex. Methods Between August 2017 and December 2018, a cross-sectional study was conducted among adult MSM in Shenyang, China. Data were collected on demographics, sexual behaviors, and RD for the most recent sexual intercourse by means of interviewer-administered face-to-face questionnaires. Blood samples were collected to test for antibodies to HIV and syphilis. Multivariable logistic regression models were used to assess the risk factors associated with HIV infection. Results A total of 515 eligible MSM participated in this survey (median age: 31 years). During the most recent anal intercourse, 28.3% (146/515) had condomless receptive anal intercourse (CRAI), 21.4% (110/515) practiced serosorting, and more than half (61.6%, 317/515) reported RD before or after anal sex. Of those practicing RD, 96.8% (307/317) conducted RD before sex, while 62.5% (198/317) conducted RD after sex. The douching devices used were primarily shower hoses (85.3%, 262/307), and relatively few MSM used commercial RD products (8.1%, 25/307) before sex. The prevalence of HIV-1 and syphilis was 11.7% and 13.2%, respectively. HIV infection was positively associated with RD, practicing RD before sex, the interaction between RD and CRAI using a shower hose for RD and other risk factors, practicing RD after sex, CRAI, using nitrite inhalants, main sexual role with males as bottom and syphilis infection. Conclusions RD is popular among Chinese MSM. Improper noncommercial RD tools use (such as shower hose), the interaction effect between RD and CRAI associated with HIV infection. Public health workers and the MSM community should publicize scientific knowledge and prevention approaches relating to RD and HIV transmission to MSM. We recommend that further studies should be conducted to understand the detailed mechanism between RD and increased HIV prevalence.
