Physiological imbalance is an abnormal physiological condition that cannot be directly observed but is assumed to precede subclinical and clinical diseases in the beginning of lactation. Alert systems to detect the physiological imbalance in a cow using Fourier transform mid-infrared spectroscopy in milk have been developed. The objective of this study was to estimate the value of information provided from such system with different indicator accuracies, herd prevalence and prices. A decision tree was created to model the probabilities of detection and associated costs of test outcome, intervention and occurrence of disease. We assumed that the negative effect of physiological imbalance was the development of subclinical ketosis and that this negative effect was prevented by drenching the cows with propylene glycol for 5 days. We simulated the economic impact of subclinical ketosis mediated through physiological imbalance to be $194 per case. The results showed that if the alert system was highly accurate (See benefits of simulation to pinpoint where additional information is needed to further quantify the economic value and required accuracy of an indication-based intervention system.Osteoporosis is a common bone metabolic disease in caged laying hens. This disease affects animal welfare and economic costs. In this study, a model of osteoporosis induced by low dietary phosphorus was established. A total of sixty 22-week-old Roman white laying hens were randomly divided into two groups, including a control group (group C) and a low dietary phosphorus group (group P). The effects of low dietary phosphorus on the endocrine and tibial osteoprotegerin (OPG)/nuclear factor kappa B receptor activating factor ligand (RANKL) signaling pathways of osteoporosis in caged laying hens were analyzed by serology, bone biomechanics, molecular biology and histopathology. The results showed that low dietary phosphorus decreased the production performance, and egg quality of laying hens and increased the contents of serum calcium (Ca), osteocalcin (OCN), alkaline phosphatase (ALP) and tartrate-resistant acid phosphatase (TRACP). The contents of serum phosphorus, calcitonin (CT), OPG and tibial biomechanics index decreased. The bone mineral density (BMD), cortical bone thickness and the expression level of OPG protein in tibia decreased. The expression of OCN, nuclear factor kappa B receptor activating factor (RANK) and RANKL protein increased. Low dietary phosphorus caused thinning and fracture of the bone trabeculae and enlargement of the bone marrow cavity of tibia. Our results suggest that phosphorus may affect bone metabolism by regulating the OPG/RANKL signaling pathway.Fish production systems in North-western Nigeria have a significant role in food, nutrition and income generations to families, yet an important setup for zoonotic disease transmission. The aim of this study was to provide a broad knowledge of the structure, activities and food safety risks of the fish value chains operating in North-western Nigeria using the value chain framework. A total of 16 focus groups and 8 key informant interviews were conducted to gather data from fish producers, fish sellers and fish processors in selected peri-urban and rural settlements in Kaduna State. In addition, 129 semi-structured questionnaires and observation checklists were used in this study to gather evidence-based data, such as demography of value chain actors, product characterization, and food safety risks. The fish value-chain in North-western Nigeria is characterised by four main stakeholders, namely, fish producers, transporters, as well as raw- and processed-fish-sellers (wholesalers, retailers). Two major sourcesinspection at all levels, lack of use of protective clothing and limited health inspection of handlers. In overall, government control of activities in fish value chains was relatively poor leading to the absence of food safety regulatory enforcement characterised by lack of institutional goals on improving food safety measures in a chain-wide distribution. Hence, this study points the significant structural, sanitary and hygiene limitations along the fish value chain components. It provides a baseline for microbial food safety risk assessments, and information required for policy-making regarding implementation of disease control programmes, as the sector is fast-evolving in Sub-Saharan Africa.The Coronavirus Disease 2019 (COVID 19) has been reported in almost every country in the world. Although a large proportion of infected individuals develop only mild symptoms or are asymptomatic, the spectrum of the disease among others has been widely variable in severity. Additionally, many infected individuals were found to have coagulation markers abnormalities. This is especially true among those progressing to severe pneumonia and multi-organ failure. While the incidence of venous thromboembolic (VTE) disease has been recently noted to be elevated among critically ill patients, the incidence among ambulatory and non-critically ill patients is not yet clearly defined. Herein, we present six patients who didn't have any hypercoagulable risk factors yet presented with pulmonary embolism in association with COVID 19 infection. LithiumChloride Furthermore, we discuss the possible underlying mechanisms of hypercoagulability and highlight the possibility of underdiagnosing pulmonary embolism in the setting of overlapping symptoms, decreased utilization of imaging secondary to associated risks, and increased turnover times. In addition, we emphasize the role of extended thromboprophylaxis in discharged patients.Background and aims There are no studies that have specifically investigated the cost-effectiveness of cascade screening of children for heterozygous familial hypercholesterolemia (FH) and treatment of affected individuals with statins to prevent coronary heart disease (CHD). This study explores the cost-effectiveness of this strategy from the perspective of the Australian public healthcare system. Methods A lifetime Markov model with four health states (Alive without CHD, Alive with CHD, Dead from fatal CHD, and Dead from other causes) was developed to simulate the progression of ten-year-old children screened for FH and treated immediately with statins if found to have FH. The underlying prevalence of FH in this target population was assumed to be 56.8%, and the sensitivity and specificity of testing were 100%. The comparator was usual care, which assumed that subjects started statins spontaneously at a later point or when they experienced a cardiovascular event. The effect of reducing low-density lipoprotein cholesterol (LDL-C) on the risk of a first event at each age assumed that risk was proportional to total lifetime exposure and was implemented using Mendelian randomisation analysis data.
