ABSTRACT: Trypanosomosis in sheep is a hemoparasitic disease of worldwide interest due to its effects on the health of animals and the economic impact on producers, is caused by the protozoan Trypanosoma sp. In the present study, the occurrence of Trypanosoma sp. in sheep from the urban-rural area of the canton Salitre was determined, through an applied study with a qualitative descriptive prospective cross-sectional approach, carried out between October 1, 2019, and February 19, 2020. Blood samples were extracted from the jugular vein and analyzed by the blood smear method using the Giemsa and Diff-Quick staining techniques. Previously, in a first study realized between 2018 and 2019, 2 cases (2%) of Trypanosoma sp., 1 case of Babesia sp. (1%), and 4 cases of Anaplasma marginale (4%) were identified, but without the presence of symptoms of the disease. However, in this new research study, of 170 animals sampled from 5 herds and aged between 3 and 8 years, 34 (20%) were positive for Trypanosoma sp., 6 for Babesia sp. (3.52%) and 6 for A. marginale (3.52%) with coinfection between them. In this research, deteriorated clinical aspects and low hematological values were also determined in positive animals; besides of the total of positive cases, 25 presented symptoms of hemoparasitic disease, 3 sheep had abortions and 8 died. The results of this study showed that Trypanosoma sp. could already become an endemic parasitosis in sheep in the country, representing a serious problem of animal health.

ABSTRACT: The prevalence of trypanosomiasis in sheep is of worldwide concern. It is a hemoparasitic disease caused by the protozoan Trypanosoma (T) spp., andthe biological cycle of transmission involves susceptible hosts and certain hematophagous flies, such as Tabanids and Stomoxys. The objective of this study was to determine the presence of Trypanosomasp. in sheep (Ovisaries). Through an applied, descriptive-prospective-cross-sectional qualitative study conducted between October 1, 2018, and January 29, 2019, blood samples extracted from the jugular vein were analyzed by the blood smear method using 2 Romanowsky staining techniques (Giemsa and Diff-Quick). Animals studied were between ages of 3 and 10 years, coming from 3 farms in the city of Colimes (Ecuador). Of 100 sampled and processed animals, 2 (2%) were positive for Trypanosoma sp., constituting the first report of this hemoparasite in sheep in Ecuador, and 1 case of Babesia spp. (1%) and 4 cases of Anaplasma marginale (4%) were also identified. However, none of these cases presented symptomatology of any hemotropic-parasitic disease. Subsequently, the positive animals were dewormed.The presence of these parasites wasconfirmedat the study site and,thus, could become a serious animal health problem.

Creative Thinking Ability

This study aims to determine the ability of creative thinking high school students in physics learning, know the form of assessment of creative thinking abilities. The study was conducted at SMAN 6 Yogyakrata. This type of research is a survey with a cross-sectional method that is a survey conducted once and at a time. The subjects were the principals, teachers of physics from SMAN 6 Yogyakrata and 30 grade XI students. observations, interviews, and questionnaires were used as data collection techniques. The data analysis method used was the quantitative-qualitative descriptive analysis. The results showed that the creative thinking ability of class XI MIA 1 students at SMAN 6 Yogyakarta can be said to be in the average and quite good category, although there are some students whose level of creative thinking ability is low. In addition, the form of assessment used by physics teachers has not been effective and accurate enough in assessing students 'creative thinking abilities. So it is recommended to use The Torrance Tests of Creative Thinking (TTCT) in physics learning because it has been proven to be accurate in assessing students' creative thinking abilities.

Objectives: To investigate the frequency, characteristics and impact of death threats by patients towards psychiatrists. Methods: A cross-sectional survey of psychiatrists (n = 60) was undertaken to investigate the frequency, characteristics and impact of death threats by patients in one Irish healthcare region serving a mixed urban–rural population of 470,000. Results: Forty-nine responses (82%) were received. Thirty-one per cent of respondents experienced death threats by patients during their careers. Victims were more likely to be male and in a consultant role. Patients making the threats were more likely to be males aged 30–60 with a history of violence and diagnosis of personality disorder and/or substance misuse. A majority of threats occurred in outpatient settings and identified a specific method of killing, usually by stabbing. Prosecution of the perpetrator was uncommon. Of the victimised psychiatrists, 53% reported that such threats affected their personal lives, and 67% believed their professional lives were impacted. In half of the incidents, there were adverse incidents subsequent to the threats, involving either the patient or the clinician. Conclusions: Death threats by patients have significant psychological and professional impacts on psychiatrists. Early liaison with employers and police and transferring the care of the patient to another clinician may be useful measures.

Abstract Background Bluetongue (BT) is a vector-borne viral disease of ruminant and camelid species which is transmitted by Culicoides spp. The causative agent of BT is bluetongue virus (BTV) that belongs to genus Orbivirus of the family Reoviridae. The clinical disease is seen mainly in sheep but mostly sub-clinical infections of BT are seen in cattle, goats and camelids. The clinical reaction of camels to infection is usually not apparent. The disease is notifiable to the World Organization for Animal Health (OIE), causing great economic losses due to decreased trade and high mortality and morbidity rates associated with bluetongue outbreaks. The objective of this study was to investigate the seroprevalence of BTV in camels in Kassala State, Eastern Sudan and to identify the potential risk factors associated with the infection. A cross sectional study using a structured questionnaire survey was conducted during 2015–2016. A total of 210 serum samples were collected randomly from camels from 8 localities of Kassala State. The serum samples were screened for the presence of BTV specific immunoglobulin (IgG) antibodies using a competitive enzyme-linked immunosorbent assay (cELISA). Results Seropositivity to BTV IgG was detected in 165 of 210 camels’ sera accounting for a prevalence of 78.6%. Potential risk factors to BTV infection were associated with sex (OR = 0.061, p-value = 0.001) and seasonal river as water source for drinking (OR = 32.257, p-value = 0.0108). Conclusions Sex and seasonal river as water source for drinking were considered as potential risk factors for seropositivity to BTV in camels. The high prevalence of BTV in camels in Kassala State, Eastern Sudan, necessitates further epidemiological studies of BTV infection in camels and other ruminant species to better be able to control BT disease in this region.

AbstractGoats are critical in mixed smallholder agricultural systems in lower and middle-income countries, while fleas are important human and animal health concerns around the world. Convenience sampling was used to describe and consider risk factors for flea infestations of peri-urban goats, with the aim of informing the iterative development of animal husbandry and management based control strategies. Seven hundred and ninety-two goats were examined in 228 households across 10 peri-urban communities surrounding Blantyre in southern Malawi. The prevalence of Ctenocephalides felis fleas was 18.3, 37.1 and 100% at the levels of individual goats, households and communities, respectively, highlighting a neglected human and animal health concern. Constant introduction of new livestock coupled to a lack of biosecurity within communities, the ubiquitous presence of dog and cat hosts for C. felis, the frequency and thoroughness of cleaning overnight goat accommodation, and goat age less than 12 months old were identified as risk factors for flea infestation. This focal cross-sectional study highlights the significance of fleas in peri-urban communities and uncovers trends and commonalities that are needed to inform sustainable disease management. The majority of the peri-urban goat keepers were female, had resided in the same community throughout their whole life and had primary level education. Advice on the planned management of fleas in livestock needs to be tailored towards this demographic group. This approach affords an opportunity to promote public health measures to address household flea infestations and zoonotic disease spread.

ObjectiveThe substantial differences in socioeconomic and lifestyle exposures between urban and rural areas in China may lead to urban–rural disparity in cancer risk. This study aimed to assess the urban–rural disparity in cancer incidence in China.MethodsUsing data from 36 regional cancer registries in China in 2008–2012, we compared the age-standardised incidence rates of cancer by sex and anatomic site between rural and urban areas. We calculated the rate difference and rate ratio comparing rates in rural versus urban areas by sex and cancer type.ResultsThe incidence rate of all cancers in women was slightly lower in rural areas than in urban areas, but the total cancer rate in men was higher in rural areas than in urban areas. The incidence rates in women were higher in rural areas than in urban areas for cancers of the oesophagus, stomach, and liver and biliary passages, but lower for cancers of thyroid and breast. Men residing in rural areas had higher incidence rates for cancers of the oesophagus, stomach, and liver and biliary passages, but lower rates for prostate cancer, lip, oral cavity and pharynx cancer, and colorectal cancer.ConclusionsOur findings suggest substantial urban–rural disparity in cancer incidence in China, which varies across cancer types and the sexes. Cancer prevention strategies should be tailored for common cancers in rural and urban areas.

Momentary Assessment

A growing body of research suggests that momentary assessment technologies that sample experiences in the context of daily life constitute a useful and productive approach in the study of behavioural phenotypes and a powerful addition to mainstream cross-sectional research paradigms. Momentary assessment strategies for psychopathology are described, together with a comprehensive review of research findings illustrating the added value of daily life research for the study of (1) phenomenology, (2) aetiology, (3) psychological models, (4) biological mechanisms, (5) treatment and (6) gene–environment interactions in psychopathology. Overall, this review shows that variability over time and dynamic patterns of reactivity to the environment are essential features of psychopathological experiences that need to be captured for a better understanding of their phenomenology and underlying mechanisms. The Experience Sampling Method (ESM) allows us to capture the film rather than a snapshot of daily life reality of patients, fuelling new research into the gene–environment–experience interplay underlying psychopathology and its treatment.

The prevalence of Cryptosporidium spp. infection in a cross-sectional study of dairy cattle, from two contrasting dairying regions in Tanzania, were determined by staining smears of faecal samples with the modified Ziehl-Neelsen technique. Of the 1 126 faecal samples screened, 19.7% were positive for Cryptosporidium spp. The prevalence was lower in Tanga Region than in Iringa Region. The prevalence of affected farms was 20% in Tanga and 21% in Iringa. In both regions, the probability of detecting Cryptosporidium oocysts in faeces varied with animal class, but these were not consistent in both regions. In Tanga Region, Cryptosporidium oocysts were significantly more likely to be found in the faeces of milking cows. In Iringa Region, the likelihood that cattle had Cryptosporidium-positive faeces declined with age, and milking cattle were significantly less likely to have Cryptosporidium positive faeces. In this region, 7% of cattle were housed within the family house at night, and this was marginally associated with a higher likelihood that animals had Cryptosporidium-positive faeces. Our study suggests that even though herd sizes are small, Cryptosporidium spp. are endemic on many Tanzanian smallholder dairy farms. These protozoa may impact on animal health and production, but also on human health, given the close associations between the cattle and their keepers. Further studies are required to assess these risks in more detail, and understand the epidemiology of Cryptosporidium spp. in this management system.

ABSTRACT Introduction U.S. Army Veterinary Corps provides highly skilled and adaptive veterinary professionals to protect and improve the health of people and animals while enhancing readiness throughout the DOD. Army veterinarians must be trained and credentialed for critical tasks within the animal health and food protection missions across all components. The Veterinary Metrics Division in the U.S. Army Public Health Center’s Veterinary Services and Public Health Sanitation Directorate is responsible for tracking readiness metrics of Army veterinarians and maintains a robust online Readiness Metrics Platform. Readiness targets were developed based on trends in readiness platform data, input of senior veterinary subject matter experts, and feedback from the field. To date, no data have been published describing the cases presented to DOD-owned Veterinary Treatment Facilities (VTFs). Without capturing and codifying the types of cases that present to the VTF and comparing to cases typically encountered during deployments, it is difficult to determine whether the VTF serves as an adequate readiness platform. In this study, we compare a representative random sample of non-wellness VTF patient encounters in garrison to cases reported from two different combat zones to determine if the VTF is a suitable clinical readiness platform. Materials and Methods Multiple data sources, including pre-existing published data and new data extracted from multiple sources, were used. The Iraq 2009-2010 dataset includes data collected from a Medical Detachment, Veterinary Service Support (MDVSS) deployed to Iraq from January 5, 2009 through August 23, 2010. The Iraq 2003-2007 dataset originated from a retrospective cross-sectional survey that included database and medical record abstraction. The Afghanistan 2014-2015 dataset includes data collected from the MDVSS deployed to Afghanistan from June 2014 to March 2015. Working dog veterinary encounter data were manually extracted from monthly and daily clinical reports. Data for the Garrison 2016-2018 dataset were extracted from the Remote Online Veterinary Record. A random representative sample of government-owned animal (GOA) and privately owned animal (POA) encounters seen across all DOD-owned VTFs from June 2016 to May 2018 were selected. Results We found that animals present to the VTF for a wide variety of illnesses. Overall, the top 10 encounter categories (90.3%) align with 84.2%, 92.4%, and 85.9% of all the encounter types seen in the three combat zone datasets. Comparing these datasets identifies potential gaps in readiness training relying solely on the VTF, especially in the areas of traumatic and combat-related injuries. Conclusions Ultimately, the success of the DOD Veterinary Services Animal Health mission depends on both the competence and confidence of the individual Army veterinarian. As the MHS transitions and DOD Veterinary Services continues to transform emphasizing readiness through a public health and prevention-based Army medicine approach, Army veterinarians must strike a delicate balance to continue to provide comprehensive health care to GOAs and POAs in the VTFs. Leaders at all levels must recognize the roles VTFs play in overall public health readiness and disease prevention through the proper appropriation and allocation of resources while fostering the development, confidence, and competence of Army veterinarians training within these readiness platforms.
