Lumpy Skin Disease: A review of epidemiological study and preventive measures

Background: Lumpy skin disease (LSD) is a highly infectious and economically important transboundary disease that is rapidly spreading to the globe. The disease causes high morbidity and a low mortality rate of infection. The animals show acute or chronic illnesses depending on the immune responses of the hosts. The economic burden of LSD manifested the poor-quality hides, a drop in milk and meat production, abortion, and death. Methods: This systematic literature review was accomplished according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The literature on lumpy skin disease has been explored over the last two decades and searched keywords on online databases such as Google Scholar, PubMed, and Scopus. Both automated and manual searching tools were used to screen the articles. The literature published other than English was rejected during the screening process. Conference papers were excluded during the screening. Results: LSD is transmitted by blood-sucking arthropods and is most prevalent in summer and rainy seasons. Exotic-bred cattle and calves are highly susceptible. Although the disease has low mortality, the high mortality of the disease prevails in endemic regions in complicated cases. Calves from unvaccinated cows should be vaccinated at any age, on the other hand, the calves from vaccinated cows should be immunized at 3 months of age. Animals should be vaccinated before the risk period. Strict biosecurity, quarantine, and immunoprophylaxis can reduce the prevalence of the disease. Conclusions: Lumpy skin disease (LSD) is an acute infectious and contagious disease affecting cattle and water buffaloes. The disease causes serious economic loss due to decreased production, skin problems, and mortality in complicated cases. Further details on genetic characterization, transmission dynamics, and host-pathogen interaction should be performed to prevent the prevalence of the disease in emerging or re-emerging countries.

Current and potential distribution of the invasive apple snail, Pomacea canaliculata in Eastern Africa: evidence from delimiting surveys and modelling studies

The invasive apple snail Pomacea canaliculata has become a significant concern in invaded habitats beyond its native range. It was reported in Kenya in 2020 invading one of the largest rice-producing schemes, the Mwea irrigation scheme. Delimiting surveys were conducted across five key rice-producing schemes (Mwea, Bura, Hola, Ahero and West Kano) in Kenya to establish the extent of the invasion and develop effective quarantine and management strategies within the Mwea scheme and other risk areas. Additionally, the ensemble model approach was used to model the potential distribution of P. canaliculata in Eastern Africa (as defined by the United Nations Geoscheme). Over 80% of the Mwea scheme was infested with P. canaliculata, an expansion from the initial infestation point (Ndekia). The mean number of adults/m2 and egg clutches/m2 were 8.4 ± 0.9 (SEM) and 7.7 ± 1.4 (SEM), respectively, with varying densities across sections. No adults or eggs of P. canaliculata were found in the four schemes outside the Mwea scheme. The model predicted high suitability for P. canaliculata in the southwest of Kenya,and in coastal areas, with all surveyed areas marked as highly suitable.. Regionally, high-risk areas include Malawi, Madagascar, and Uganda. Mozambique, Tanzania, and Ethiopia showed localised areas of high suitability. Conversely, Sudan, South Sudan, Eritrea, Djibouti and Somalia were largely unsuitable for P. canaliculata. Given the potential for further spread, strict quarantine measures are essential to prevent the spread of P. canaliculata in Kenya and its introduction to uninvaded regions of Eastern Africa. Alongside this, implementing IPM e strategies is crucial for effective pest management and the protection of agricultural ecosystems.

Identification of Haemoproteus infection in an imported grey crowned crane (Balearica regulorum) in China

Blood parasites from the order Haemosporida infect many vertebrates and cause malaria-like diseases. In this study, a haemosporidian infection was detected in a sick grey crowned crane imported into China using a combination of morphological and molecular approaches. Blood samples were collected from the jugular vein and processed for morphological identification of infective parasites using stained blood smears and microscopy. No merogony occurs in the blood cells, and sporadic pigment granules were observed. Nested-PCR assays were employed for a molecular examination, which indicated that the cytb gene of this parasite had 94.1–94.9% identity to Haemoproteus antigonis. Subsequently, its mitochondrial genome structure was determined by high-throughput sequencing using the DNBSEQ-T7 platform. The determined structure was confirmed by the Sanger sequencing using amplicons. The mitochondrial genome obtained for this parasite exhibited a low CG content (32.0%) and possessed three protein-coding genes, encoding 1068 amino acids, which constituted 53.7% of the genome. Phylogenetic analysis indicated that this parasite clustered with Haemoproteus sp. is detected in grey crowned cranes from Africa. This parasite was likely acquired during importation of this animal; thus, strict quarantine of imported ornamental animals is required to prevent the entry of new pathogens.

Diagnostic study on major honeybee disease, pests and predators in North Western Ethiopia.

The study was conducted in Pawe district from Benishangul-Gumuz and Jawi and Fagita Lekoma districts from the Amhara region to investigate major honeybee pests, predators and diseases. Using a purposive sampling technique, 183 households were interviewed, and 240 samples were collected for laboratory analysis of bee disease; data were analysed using descriptive statistics. The share of hive types owned by sampled respondents was 88.6%; overall, 1.1% and 10.3% were traditional, transitional and modern beehives, respectively. About 92% of the sample respondents acquired their base colonies by catching swarm bees on the apex of trees. The majority of beekeepers executed external inspections of their colony, whereas only 50% carried out internal inspections. Based on the responses of beekeepers, around 48.9%, 56.3% and 23.1% of colonies absconded every year from Pawe, Jawi and Fagita Lekoma districts, respectively. Ants, wax moths, bee lice, beetles, spiders, birds, monkeys and honey badgers were the major honeybee pests and predators discovered in study areas in decreasing order. Concerning the incidence of Varroa mites, Nosema apis and amoeba disease, 27.5%, 60% and 71.6% of samples showed positive results in study locations, respectively. From this result, we observed that ants, wax moths, bee lice, beetles, spiders, birds, monkeys and honey badgers were the major honeybee pests and predators. The prevalence of amoeba disease was comparatively higher in highland areas and in the summer season. This finding suggests the need for the alertness of beekeepers in controlling bee disease and pests and strengthening bee colonies through seasonal colony management. There should be a strict quarantine, and check-up undertaken when a new colony is purchased from one region to another is essential.

The impact of social isolation on smartphone addiction among college students: the multiple mediating effects of loneliness and COVID-19 anxiety.

The widespread use of smartphones has significantly increased smartphone addiction among college students, especially during the COVID-19 pandemic. Since the COVID-19 outbreak, university campuses in mainland China have strictly followed the Chinese government's strict quarantine policy, including closed campus management, prohibitions against gatherings, and social distancing, increasing student loneliness and anxiety and thus increasing the risk of smartphone addiction. Extant Studies have revealed that social isolation is a prominent predictor of smartphone addiction but have failed to systematically explore the complex relationship between social isolation and smartphone addiction in the context of COVID-19; therefore, the underlying mechanisms of these factors in the post-pandemic era are unclear. This study is the first attempt to consider loneliness, COVID-19 anxiety and social isolation as a whole and to clarify the underlying mechanisms of social isolation and smartphone addiction by constructing a multiple mediating model. This study included students enrolled at eight higher education institutions in Conghua District (Guangzhou city). Quota proportional sampling was adopted, 900 self-report questionnaires were distributed through the WeChat groups of these universities from December 10 to December 15, 2022, and 868 valid questionnaires (620 females, 248 males) were ultimately obtained. The direct effect of social isolation on smartphone addiction was significant, and loneliness and COVID-19 anxiety mediated the association between social isolation and smartphone addiction in both parallel and sequential ways. Moreover, a reverse mediation model with COVID-19 anxiety as the first mediator and loneliness as the second mediator was found. College students who experience social isolation are at greater risk for smartphone addiction, and the core factor leading to their smartphone addiction is the subjective psychological state triggered by campus isolation and social distancing, such as loneliness and anxiety. These risky behaviors of people should receive extra attention, and psychological factors such as loneliness and COVID-19 anxiety should be considered in future therapies aimed at reducing addiction.

Adapting of Mental Healthcare Facilities to the COVID-19 Challenges

The healthcare sector is one of the largest in the US economy (generating about 18% of GDP). It is the main employer of American workers. Unfortunately, it has been one of those most affected by the COVID-19 pandemic, as certain medical services had to be suspended under strict quarantine (at least 150 hospitals in the US were forced to send employees on leave or dismiss them, primary care practices reported a 70% decrease in the number of patients). The purpose of the article is to analyse challenges in the US healthcare sector during COVID-19 and to justify ways to overcome these challenges (on the example of the Life Chance Mental Health Medical Group, a leading provider of mental health services in the US with a strong regional network, established good reputation and a wide and loyal customer base). The case of this company was chosen in this context based on the fact that, as the SWOT analysis in the article showed, during the COVID-19 pandemic, the greatest vulnerabilities of medical institutions in the mental health sector are related to the quality of basic services (face-to-face therapy sessions). That is significantly reduced if provided online. In order to operate effectively even during epidemics and pandemics, companies in this specific area should expand partnerships with telemedicine platforms, transform their product portfolio, and ensure that their doctors’ qualification profiles meet the requirements of remote therapy. The article analyses the mechanisms for overcoming pandemic challenges in mental healthcare facilities using the postulates of transformational leadership theory, change management theory, theory of constraints, and organisational culture theory.

GENESIS OF RECREATIONAL SETTLEMENTS IN THE UKRAINIAN CARPATHIANS IN THE 21ST CENTURY

The article examines the phenomena of the emergence and spontaneous evolution of a new type of recreational facilities for the Ukrainian Carpathians region – multi-format recreational settlements that combine private rental residential units with their partial functioning, in the form of rental recreational housing, in the structure of a management company. The prerequisite for the emergence of this type of recreational facilities was the construction of a large ski complex in Bukovel. Accommodation in this complex offered both traditional hotels and comfortable single-family cottages. And these cottages turned out to be the most popular among vacationers and it were they that became a clear example for residents of surrounding villages and towns, who quickly adapted their own surroundings “for tourists.” After russia's occupation of Crimea in 2014, a significant number of the Ukrainian population redirected their holidays to the Carpathian region. The summer holiday season in the mountains has become as widespread and crowded as the winter season. Consequently, recreational facilities in the Ukrainian Carpathians over the course of 1- 2 years were transformed from single-season to year-round establishments, and the summer season surpassed the traditional winter season in terms of profitability. The global Covid 19 pandemic with strict long-term quarantine, psychological stress, and total remote work became the next strong impetus for popularizing the idea of owning a single-family cottage in the environmentally friendly, safe Carpathians. At that time, quarantined Europe and open Ukraine, a visa-free regime and the opening of a number of low-cost airlines to the Gulf countries also resulted in the appearance of a huge number of tourists from the Arab world in the Carpathians.The desire to own a single-family cottage in the Carpathians grew stronger after the large-scale russian invasion in February 2022, as all the delights of the Carpathians added to the feeling of safety from bombings and missile attacks. The response to this demand was the offer of private estates, apart-hotels, small cottage communities, and entire recreational settlements with developed internal infrastructure. The owner of such a building in a recreational settlement can live in it all the time. However, during absence, the management company of a recreational settlement has the right to rent out its building to third parties under the terms of a preliminary agreement with its owner. Thus, this property passively generates income for the owner during the period when he and his family are in another place. Technical issues of maintaining or repairing a building, providing energy resources, developing the territory, landscaping, etc. provided by the management company. Taking this into account, investing capital in exactly this type of real estate in the Ukrainian Carpathians is quite promising and relevant in our time.

High-throughput sequencing for plant virology diagnostics and its potential in plant health certification

High-throughput sequencing (HTS) technologies have revolutionized plant virology through simultaneous detection of mixed viral infections. HTS advances have uncovered and improved understanding of virus biology, ecology, and evolution which is vital for viral disease management. Plant viruses continue to threaten global agricultural productivity and strict quarantine measures are essential to prevent the introduction and spread of virulent viruses around the world. The gradual decrease in HTS operational costs, including improved computational systems and automation through robotics, has facilitated the adoption of this tool for plant diagnostics, including its use in surveillance and quarantine programs. However, the speed of technology advancements and distinct HTS chemistries, laboratory procedures, data management, and bioinformatic analyses have proven challenging. In addition, the lack of viral species reference sequences, compared with the estimated number of distinct viral taxa, makes classification and identification of novel viruses difficult. There is a need for standardized HTS testing, especially within plant health programs. In this review, we consider the application of HTS in plant virology, explore the technical challenges faced and the opportunities for HTS in plant health certification. We propose standards for overcoming current barriers and for ensuring reliable and reproducible results. These efforts will impact global plant health by reducing the risk of introduction and the spread of damaging novel viruses.

The Twitch Boom: The Rise Of The Plataform Due To The Impact Of The Covid-19 Pandemic

The COVID-19 pandemic led various countries worldwide to implement social distancing measures and strict quarantines, resulting in changes in people's daily consumption habits. The increase in time spent at home fostered new forms of home entertainment, driving various types of online entertainment and interaction. The main objective of this study is to measure and analyze the impact of the pandemic's effects on content consumption on an online live streaming platform, Twitch. The research method involved the use of data related to the average total views on the platform, aiming to determine the initial and prolonged effects of the pandemic on the behavior and evolution of consumed content on the platform. Statistical techniques employed included Regression Discontinuity and Differences in Differences. The results suggest that the pandemic led to an increase in the number of concurrently connected users by 30% to 40%. Furthermore, it is observed that this change in the platform's viewership level persists over time, maintaining the growth trend observed before the pandemic at the new post-pandemic level.

Predicting suitable areas for Metcalfa pruinosa (Hemiptera: Flatidae) under climate change and implications for management.

Climate change is a prominent factor reshaping the distribution of invasive species. Metcalfa pruinosa (Say 1830) (Hemiptera: Flatidae), native to North America, has invaded other continents and poses a serious threat to various agricultural crops and the human residential environment. Understanding the distribution of M. pruinosa based on climatic conditions is a critical first step to prevent its further invasion. Therefore, based on its occurrence records and associated environmental variables, a Maxent model was developed to predict suitable areas for this species in the present and future on a global scale. The model exhibited outstanding performance, with a mean area under the receiver operating characteristic curve and true skill statistic values of 0.9329 and 0.926, respectively. The model also indicated that annual precipitation (Bio12) and max temperature of the warmest month (Bio5) were the key environmental variables limiting the distribution of M. pruinosa. Moreover, the model revealed that the current suitable area is 1.01 × 107 km2 worldwide, with southern China, southern Europe, and the eastern United States predicted to be the primary and highly suitable areas in the latter 2 regions. This area is expected to increase under future climate scenarios, mainly in the northern direction. The study's findings contribute to our understanding of climate change's impact on M. pruinosa distribution, and they will aid governments in developing appropriate pest management strategies, including global monitoring and strict quarantine measures.

Characterization and pathogenicity of Colletotrichum camelliae causing brown blight disease of tea (Camellia sinensis) in Malaysia

Tea (Camellia sinensis (L.) Kuntze) is a dicotyledonous woody shrub species widely cultivated to produce a beverage made from its leaves. Brown blight is a destructive foliar fungal disease that reduces tea production and degrades quality, resulting in lower market value. Typical brown blight symptoms observed in three commercial tea plantations in Malaysia were characterized as brownish to black lesions on young leaves. The lesions expanded with age, becoming darker and developing into necrotic cells. A total of 45 fungal isolates were isolated from brown blighted tea leaves and identified as Colletotrichum camelliae. Morphological characteristics coupled with universal spacer region and multigene phylogenetic relationships using the internal transcribed spacer (ITS), β-tubulin (tub2) and glyceraldehyde-3-phosphate dehydrogenase (gapdh) were used to accurately identify fungal isolates. The results of the pathogenicity test revealed that C. camelliae was responsible for causing brown blight disease of tea. This study highlights the occurrence of C. camelliae which causes tea brown blight in Malaysia. These findings may assist in disease monitoring, strict quarantine and effective control management of diseased tea plants.

Clavibacter tessellarius causing bacterial mosaic of wheat establishes in the Old World

AbstractThe genus Clavibacter (family Microbacteriaceae) includes gram‐positive actinobacterial species infecting diverse agricultural crops such as alfalfa, maize, pepper, potato, tomato and wheat. Clavibacter tessellarius, causing bacterial mosaic of wheat, was reported for the first time in 1976 in Nebraska (United States). Since then, the pathogen was thought to be restricted to North America (Canada and the United States). While bacterial strains suspected to be C. tessellarius have occasionally been isolated from wheat samples outside North America, occurrence of the pathogen in the Old World has not yet been confirmed by the plant protection authorities. In spring 2020 (January to May) dozens of wheat fields with young plants showing leaf chlorosis and mild mosaic symptoms were surveyed and sampled in southern Iran. Among 192 surveyed wheat fields, gram‐positive, orange‐pigmented actinobacterial strains were isolated from samples of 53 fields. Altogether, 61 bacterial strains were identified as C. tessellarius based on the phenotypic features, PCR‐based molecular tests and pathogenicity assays. Multilocus sequence analysis of five housekeeping genes (atpD, dnaK, gyrB, ppk and rpoB) using 10 representative strains from diverse geographic areas in southern Iran confirmed the phylogenetic status of the strains within C. tessellarius. Our data indicate that the bacterial mosaic pathogen occurs in four southern Iranian provinces including Bushehr, Fars, Kerman and Khuzestan. Thus, occurrence of C. tessellarius outside North America is confirmed. Potential risks associated with the emergence of the pathogen in the Old World, and the need for strict quarantine measures in the area, is further discussed.

Measuring the Spatial-Temporal Heterogeneity of Helplessness Sentiment and Its Built Environment Determinants during the COVID-19 Quarantines: A Case Study in Shanghai

The COVID-19 outbreak followed by the strict citywide lockdown in Shanghai has sparked negative emotion surges on social media platforms in 2022. This research aims to investigate the spatial–temporal heterogeneity of a unique emotion (helplessness) and its built environment determinants. First, we scraped about twenty thousand Weibo posts and utilized their sentiments with natural language processing (NLP) to extract helplessness emotion and investigated its spatial–temporal variations. Second, we tested whether “helplessness” was related with urban environment attributes when other real estate economic and demographic variables were controlled using the ordinary least squares (OLS) model. Our results confirmed that helplessness emotion peaked in early April when the lockdown started. Second, residents in neighborhoods characterized by higher rents and property management fees, higher population density, lower housing prices, lower plot ratios, or surrounded by less tree view and higher perceived visual complexity, are found to exhibit higher degree of “helplessness”. This study provides an effective data-driven framework to utilize social media data for public sentiments monitoring. The helplessness emotion identified is a unique mental distress under strict quarantine measures, which expands the growing literature of urban governance in the post-pandemic era. Decision makers should pay attention to public opinions and design tailored management measures with reference to civic emotion dynamics to facilitate social sustainability and resilience in face of future crises.

Mathematical Modeling Of the Spread of COVID-19, Taking Into Account the Distribution of Asymptomatic Cases between Actually Asymptomatic and Pre-Symptomatic Cases

The possibility of representation in a dynamic model of the three types of SARS-CoV-2 infection: asymptomatic, pre-symptomatic and symptomatic is studied. Furthermore, a compartmental model was proposed, with a branching of asymptomatic cases into pre-symptomatic and actually asymptomatic cases. Verification of the proposed model using data from the first wave of COVID-19 in St. Petersburg and the proportion of actually asymptomatic cases among all asymptomatic cases demonstrated adequate model behavior. The contribution of pre-symptomatic cases to the total number of symptomatic cases was studied. The need to account for the high proportion of asymptomatic carriers in strict quarantine was identified.

Behavioral game of quarantine during the monkeypox epidemic: Analysis of deterministic and fractional order approach

This work concerns the epidemiology of infectious diseases like monkeypox (mpox) in humans and animals. Our models examine transmission scenarios, including transmission dynamics between humans, animals, and both. We approach this using evolutionary game theory, specifically the intervention game-theoretical (IGT) framework, to study how human behavior can mitigate disease transmission without perfect vaccines and treatments. To do this, we use non-pharmaceutical intervention, namely the quarantine policy, which demonstrates the delayed effect of the epidemic. Additionally, we contemplate quarantine-based behavioral intervention policies in deterministic and fractional-order models to show behavioral impact in the context of the memory effect. Firstly, we extensively analyzed the model's positivity and boundness of the solution, reproduction number, disease-free and endemic equilibrium, possible stability, existence, concavity, and Ulam-Hyers stability for the fractional order. Subsequently, we proceeded to present a numerical analysis that effectively illustrates the repercussions of varying quarantine-related factors, information probability, and protection probability. We aimed to comprehensively examine the effects of non-pharmaceutical interventions on disease control, which we conveyed through line graphs and 2D heat maps. Our findings underscored the significant influence of strict quarantine measures and the protection of both humans and animals in mitigating disease outbreaks. These measures not only significantly curtailed the spread of the disease but also delayed the occurrence of the epidemic's peak. Conversely, when quarantine maintenance policies were implemented at lower rates and protection levels diminished, we observed contrasting outcomes that exacerbated the situation. Eventually, our analysis revealed the emergence of animal reservoirs in cases involving disease transmission between humans and animals.

Health-Related Quality of Life in Adolescents during Quarantines Due to COVID-19 Pandemic: The Effect of Physical Activity and Gender

Given that deterioration of adolescents’ health status during pandemic is well documented, health related quality of life (HRQoL) assessment is very important, as it contributes in adolescents’ development and maturation into healthy adults. The main purpose of the study was to assess adolescents’ HRQoL during the two strict lockdowns due to COVID-19. Secondary aims were to examine differences in HRQoL with regard to gender, and physical activity/sport participation before and during lockdowns. It was a cross-sectional study and conducted during first and second strict lockdowns. Three hundred and sixty-three adolescents (Ν=363) from secondary schools, in the Greek territory (108 boys and 255 girls) filled in the TNO-AZL Questionnaire for Children’s Health-Related Quality of Life Children’s Form, online, once. Also, demographic and anthropometric data were collected. For all TACQOL-CF subscales results showed that scores were lower, than the maximum subscales scores. Also, adolescents’ responses to open questions supported further the low subscales scores. In addition, adolescents who participated in sport before lockdowns reported better scores in motor functioning/performance during lockdowns than their non-physically active peers (p<0.05). Moreover, girls reported significantly lower scores compared to boys in general physical functioning/complaints subscale (p<0.05). The findings of this study highlighted that during the two strict quarantines adolescents’ HRQoL was deteriorated. Sport participation before the pandemic influenced positive HRQoL during quarantines and also quarantines affected differently adolescents by gender. Thus, the results should give information in adopting preventive strategies by policy makers to alleviate long-term negative consequences, in order adolescents to gain pre-pandemic HRQoL levels, in the transitional post-COVID-19 era.

Prevalence and risk factor analysis of lumpy skin disease in cattle population of Banskhali Upazila, Chattogram, Bangladesh

Objective: This investigation aimed at assessing the outbreak scenario of the disease in Banskhali Upazila, Chattogram district, Bangladesh. The epidemic was recorded in several areas of Bangladesh, but Banskhali Upazila was rarely mentioned in references. The study evaluated clinical features, and treatment protocol and identified risk factors associated with lumpy skin disease (LSD) in the cattle population of the study area. Materials and Methods: In the four months leading up to December 2020, 53 incidents involving cattle of four different ages and two different breeds were observed in Upazila Veterinary Hospital (UVH), Banskhali, Chattogram. 19 of them had been presumptively diagnosed with LSD based on the owners’ complaints, clinical histories, skin lesions unique to LSD, and associated risk factors. Results: The overall clinical prevalence of LSD was 35.85%, with a mortality rate of 1.88%. Fever and distinctive skin nodules were consistently noted at the highest frequency in affected cattle. Male (39.39%), crossbred (19.35%), and non-vaccinated (40%) cattle showed a significantly higher prevalence of the disease compared to their counterparts. Autohemotherapy, coupled with the administration of the antiviral drug acyclovir, systemic antibiotics such as streptopenicillin (36.84%), and the use of analgesics, anti-inflammatory agents, and antihistamines, were routinely utilized as supportive treatments for the disease. Conclusion: Strict quarantine, vector control, recording of outbreak pattern recording, and prophylactic vaccination may be the best treatments for lowering the disease’s risk factors for the disease. These findings may provide essential groundwork for further investigations to prevent further relapses or outbreaks of LSD in the future.

Infectious bovine rhinotracheitis: Epidemiology, control, and impacts on livestock production and genetic resources

The present review aims to determine the epidemiology of infectious bovine rhinotracheitis (IBR), control measures, and its impact on livestock production and genetic resources. The literature search was conducted to select and compile peer-reviewed journals, book chapters, and international organization proceedings on the epidemiology, control, and impacts of IBR. IBR is a highly contagious disease of cattle that causes substantial economic losses throughout the world, particularly in the dairy and beef industries. Bovine alphaherpesvirus-1 causes this infectious viral disease, affecting the respiratory, and reproductive systems. IBR causes severe inflammation and dysfunction of the respiratory system. Infection of the reproductive system is responsible for abortion, retained placenta, metritis, and balanoposthitis. The transmission is by inhalation, contact with nasal and genital secretions, and fomites. Epidemiologically, the disease is known for its distinct latency characteristics. The infectious agent establishes a lifelong latent infection in the peripheral nervous system. The introduction of latently infected cattle, high stocking densities, confined pens, concurrent diseases, and low ambient temperatures increase the transmission and severity of the disease. The disease has no specific drug treatments, so control and prevention measures have inevitable roles. IBR is a significant constraint on livestock production globally, particularly in developing countries. It causes poor reproductive performance and productivity, the loss of replacement herds, and the culling of mature, productive animals. The implementation of strict biosecurity measures, immunization, quarantine, herd screening, and proper herd management are the most important control and prevention strategies.

Climate Change and its Impact on Animal Health: Adapting and Mitigating the Risks

Climate change is a critical global issue affecting animal health, with rising temperatures and erratic weather patterns posing new challenges. Animals play a vital role in maintaining ecosystem balance and biodiversity, and their health can be affected by climate change-induced disruptions. Strategies to mitigate these risks include sustainable agricultural practices, research for vaccines and treatments, and implementing proactive measures. Climate change can increase the risk of disease transmission, invasive species, and disrupt ecosystems, leading to decreased reproductive success and population dynamics. Preventative measures include surveillance, vaccination programs, and habitat management. Adaptation strategies for animal health include implementing sustainable agricultural practices, investing in research and development, and promoting biodiversity preservation. To combat diseases, adaptation strategies for animal health should focus on enhancing disease surveillance, promoting biosecurity measures, and improving veterinary healthcare services. These strategies include robust disease surveillance systems, strict quarantine protocols, proper hygiene practices, and educating farmers about biosecurity. Vaccination programs, heat stress management techniques, and wildlife corridors can also help prevent vector-borne diseases, protect livestock and domesticated animals, and ensure the survival of threatened species. Mitigation strategies should also be implemented to protect animal populations and human health.

Emotional eating and mental health of nurses working in Lebanese hospitals during the double crisis.

The 2019 coronavirus (COVID-19) pandemic and strict quarantine increased the likelihood of mental symptoms and abnormal eating behaviours. This study aimed to assess the magnitude of emotional eating (EE) among nurses working in Lebanese hospitals and its association with mental health. A cross-sectional study was conducted among nurses aged between 18 and 50 years working in Lebanese hospitals during the COVID-19 outbreak and the economic crisis. A total of 303 nurses consented to participate. The mean EE score was 28.56 (±8.11). The results of this study revealed that 53.8% of the nurses reported depression, 58.1% suffered from anxiety and 95.1% experienced either moderate or severe stress. The study concluded that females (β = 8.112, P = 0.004), non-smokers (β = -4.732, P = 0.01) and depressed nurses (β = 0.596, P = 0.046) had a higher tendency towards EE. Additionally, it was found that EE was associated with weight gain (β = 6.048, P = 0.03) and increased consumption of fried foods (β = 5.223, P = 0.001). Females experienced more stress (β = 2.244, P = 0.003) and anxiety (β = 1.526, P = 0.021) than their male counterparts. With regard to mental health, depression was associated with weight gain (β = 2.402, P = 0.003) and with lower consumption of healthy foods such as nuts (β = -1.706, P = 0.009) and dishes prepared with sofrito sauce (β = -1.378, P = 0.012). These results can help the health authorities to design preparedness plans to ensure proper mental and physical well-being of nurses during any unforeseen emergencies.
