Although there have been remarkable technological developments in healthcare, the privacy and security of mobile health systems (mHealth) still raise many concerns with considerable consequences for patients using these technologies. For instance, potential security and privacy threats in wireless devices, such as Wi-Fi and Bluetooth connected to a patient hub at the application, middleware and sensory layers, may result in the disclosure of private and sensitive data. This paper explores the security and privacy of the patient hub, including patient applications and their connections to sensors and cloud technology. Addressing the privacy and security concerns of the patient hub called for a comprehensive risk assessment by using the OCTAVE risk assessment framework. Findings reveal that the highest risk concerned data exposure at the sensory layer. In spite of the countermeasures presented in this paper, most served as a means to identify risk early as opposed to mitigating them. The findings can serve to inform users of the potential vulnerabilities in the patient hub before they arise.

Sero-Prevalence and Risk factors of Contagious Bovine Pleuropneumonia (CBPP) in Afgoye District Lower Shabelle Region, Somalia

Open Journal of Veterinary Medicine 2024年第2期14卷 11-20页

作者： Ahmed mohamed Ahmed Sumaya Hassan ali Abdisalam mohamed ali Abdirazack Saleban Osman Binti abubakar mohamed Abdifatah Mohamud Ibar Shafii Abdullahi mohamed mohamed Abdelrahman mohamed Ahmed ali Omar Zakaria Ibrahim Issack College of Veterinary Medicine Abrar University Mogadishu Somalia Faculty of Veterinary Medicine and Animal Husbandry Somali National University Mogadishu Somalia Faculty of Veterinary Science Benadir University Mogadishu Somalia

Contagious bovine Pleuropneumonia (CBPP) is an infectious and highly contagious respiratory disease of cattle and water buffalo, caused by the Mycoplasma mycoides subspecies mycoides. It induces significant economic losses and leads to a severe livestock production problem, negatively influencing people’s livelihoods of affected countries. In Somalia, there is no updated data on the prevalence and distribution of the disease. Hence, a descriptive cross-sectional study was conducted from September 2022 to June 2023 in different villages under the Afgoye District of lower Shabelle region, Somalia. The main purpose of this study is to assess the sero-prevalence and identify the associated risk factors for the occurrence of the disease. In this study, villages, age, sex, breed, and body condition were considered as risk factors. A total of 90 blood samples were collected and tested in the laboratory using the Anti-CBPP Elisa kit test. Out of 90 serum samples from herd cattle, 32 were positive, resulting in an overall prevalence of 35.5%. In addition, we found a statistically significant variation between the prevalence of the disease and factors such as sex, age, body condition and breeds. In summary, the overall prevalence of Contagious bovine pleuropneumonia in this study area is worth to be considered because there is a low quality of health care and less awareness of the Contagious bovine Pleuropneumonia effects on herds, which warrants the official authorities to act and follow appropriate preventive and control measures to reduce the incidence of the disease and generate appropriate controlling and prevention measures in all regions of Somalia.

Background: Chondrocytes in the growth plate(GP) undergo increases in volume during different cascades of cell differentiation during longitudinal bone growth. The volume increase is reported to be the most significant variable in understanding the mechanism of long bone ***: Forty-five postnatal Sprague-Dawley rat pups, 7-15 days old were divided into nine age groups(P7-P15). Five pups were allocated to each group. The rats were sacrificed and tibia and metatarsal bones were harvested. Bone lengths were measured after 0, 24, 48, and 72 hours of ex vivo incubation. Histology of bones was carried out, and GP lengths and chondrocyte densities were ***: There were significant differences in bone length among the age groups after 0 and 72 hours of incubation. Histological sectioning was possible in metatarsal bone from all age groups, and in tibia from 7-to 13-day-old rats. No significant differences in tibia and metatarsal GP lengths were seen among different age groups at 0 and 72 hours of incubation. Significant differences in chondrocyte densities along the epiphyseal GP of the bones between 0 and 72 hours of incubation were observed in most of the age ***: Ex vivo growth of tibia and metatarsal bones of rats aged 7-15 days old is possible, with percentage growth rates of 23.87 ± 0.80% and 40.38 ± 0.95%measured in tibia and metatarsal bone, respectively. Histological sectioning of bones was carried out without the need for decalcification in P7-P13 tibia and P7-P15 metatarsal bone. Increases in chondrocyte density along the GP influence overall bone elongation.

Prevalence of Bovine Tuberculosis in Sheep at Sadar and Parbatipur Upazila under Dinajpur District in Bangladesh

Open Journal of Veterinary Medicine 2021年第11期11卷 315-326页

Haydar ali Binti abubakar mohamed Head of Lab at Someat Company Mogadishu Somalia Faculty of Veterinary Science in Benadir University Mogadishu Somalia Faculty of Veterinary and Animal Science Department of Pathology and Parasitology in Hajee Mohammad Danesh Science and Technology University Dinajpur Bangladesh Faculty of Veterinary Medicine and Animal Husbandry at Horsed International University Mogadishu Somalia

Tuberculosis is Zoonotic disease and infected animals continue to spread the disease to other animals and humans by excreting the germs in milk, meat, feces, and respiratory droplets, this study used bPPD (Bovine purified protein derivative) to observe TST (Tuberculin skin test) reactivity in the Sheep population in the Sadar and Parbatipur Upazilas of Dinajpur District. The research conducted from January to June of 2018. There is no history for sheep tuberculosis in the study area. Overall, 5 percent (7/140) of 140 sheep were positive, 15% (21/140) were doubtful, and 80% (112/140) were negative based on sex, age, breed, and body condition score, while lactation stage and reproduction status prevalence was 6.4 percent, 14.9 percent, and 78.7% positive, doubtful, and negative, respectively. Our findings suggest the presence of a skin test reaction response when employing the bPPD reagent, but this needs to be validated by pathological and serological techniques. Nevertheless, my preliminary investigation suggests that abattoirs must implement effective control systems and raise public awareness.
