Foot-and-mouth disease virus dynamics in border areas of Pakistan with Afghanistan.

BACKGROUND: Foot and mouth disease (FMD) is a highly contagious disease that impacts cloven-hoofed animals globally. The illegal trade of livestock between the border regions of Pakistan and Afghanistan can contribute to the spread of this disease. This study focuses on investigating the outbreaks of FMD that occurred in this area from June 2020 to May 2021. METHODS: RESULTS: A total of 233 epithelial tissue samples were collected, and 77% were found positive for FMDV through an antigen-detection by ELISA and molecular conformation through RT-PCR. The study found three serotypes of FMDV dominating in the border area of Pakistan with Afghanistan: O, A, and Asia-1. The outbreak activity was peaked between August/September followed by July/October 2020. Phylogenetic analysis conducted using the VP1 region sequence showed that serotype O isolates belonged to the Middle East-South Asia (ME-SA) topotype, PanAsia-2 lineage, and ANT-10 sub-lineage, while serotype Asia-1 isolates belonged to a novel lineage BD-18.The highest prevalence of serotype O of FMDV was found in cattle and buffalo of 1-2 year age group, while the highest outbreak ratio of serotype O was recorded in goats of 0-1 year age group and sheep of > 2 year age group. The serotype O was more prevalent in male than female sheep. The type A was more prevalent in females of sheep and goats than their corresponding males. The serotype Asia-1 was more prevalent in females of cattle and sheep than their corresponding males. The outbreak epidemiology of FMD varied significantly between various regions, months of study, animal species, age groups, and gender. CONCLUSIONS: The study found that FMD outbreaks in the border area of Pakistan and Afghanistan were diverse and complicated, and that different types of FMDV were circulating. The study recommended effective actions to stop FMD transmission in this area.

Smoking cessation interventions in South Asian Region: a systematic scoping review.

BACKGROUND: Cigarette smoking is one of the most preventable causes of morbidities and mortalities. Since 2005, the World Health Organization Framework Convention for Tobacco Control (WHO-FCTC) provides an efficient strategic plan for tobacco control across the world. Many countries in the world have successfully reduced the prevalence of cigarette smoking. However, in developing countries, the prevalence of cigarette smoking is mounting which signifies a need of prompt attention. This scoping review aims to explore the extent and nature of Smoking Cessation (SmC) interventions and associated factors in South Asian Region (SAR) by systematically reviewing available recently published and unpublished literature. METHODS: The Joanna Briggs Institute (JBI) framework frames the conduct of this scoping review. PubMed, EBSCO CINAHL Complete, Cochrane Library, ProQuest Dissertation and Theses, and local websites as well as other sources of grey literature were searched for relevant literature. In total, 573 literature sources were screened. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow diagram, finally, 48 data sources were included for data extraction and analysis. We analyzed the extracted SmC interventions through the FCTC. Factors that affect smoking cessation interventions will be extracted through manual content analysis. RESULTS: Regarding FCTC recommended smoking cessation strategies (articles), most of the articles were either neglected or addressed in a discordant way by various anti-smoking groups in SAR. Key barriers that hamper the effectiveness of smoking cessation interventions included lack of awareness, poor implementation of anti-smoking laws, and socio-cultural acceptance of tobacco use. Conversely, increased levels of awareness, through different mediums, related to smoking harms and benefits of quitting, effective implementation of anti-smoking laws, smoking cessation trained healthcare professionals, support systems, and reluctance in the community to cigarette smoking were identified as facilitators to smoking cessation interventions. CONCLUSION: The ignored or uncoordinated FCTC's directions on smoking cessation strategies have resulted in continued increasing prevalence of cigarette smoking in developing countries, especially SAR. The findings of this review highlight the need for refocusing the smoking cessation strategies in SAR. STRENGTHS: The review was conducted by a team of expert comprising information specialists, and senior professors bringing rich experience in systematic and scoping reviews. Every effort was made to include all available literature sources addressing cigarette SmC and associated factors in SAR. The review findings signal the need and direction for more SmC efforts in SAR which may contribute to development of effective policies and guidelines for the control of smoking prevalence. LIMITATIONS: Despite efforts, potentially relevant records may have been missed due to unpublished or inaccessible articles, unintended selection bias, or those published in local languages, etc. Moreover, the exclusion of literature on under 18 participants and mentally ill smokers may limit the generalizability of findings.

Foot-and-mouth disease seroprevalence is higher in young female crossbred sheep and goats compared to their counterparts in the border area between Pakistan and Afghanistan.

OBJECTIVE: Foot-and-mouth disease (FMD) is a highly contagious disease in ruminants that causes significant economic losses worldwide. However, the prevalence of FMD virus (FMDV) in small ruminants has been overlooked in Pakistan. This study aimed to determine the prevalence of FMD in sheep and goats in the border area between Pakistan and Afghanistan. ANIMALS: 800 sheep and goats belongs to age groups of 6 month to > 2 years. METHODS: A total of 800 serum samples were collected from sheep (n = 424) and goats (n = 376) and subjected to structural protein (SP) and 3ABC non-SP (NSP) ELISAs for the detection of antibodies against SP and NSP of the FMDV. RESULTS: For NSP, 340/800 (42.5%) of samples were positive, while SP analysis revealed that serotype O (44.5%) was the most common in sheep and goats, followed by Asia-1 (42%) and A (32%) serotypes. Sheep (39%; 95% CI, 34 to 44) had a higher (P < .05) prevalence of FMD than goats (46%; 95% CI, 41 to 51). Statistically significant (P < .05) differences in the seroprevalence of FMD-SP and FMD-NSPs were observed between various agencies (areas) of the study area. Risk factors such as age, sex, breed, season, flock size, body condition, animal movement, and production system were significantly (P < .05) associated with FMDV prevalence. CONCLUSIONS: This study showed that FMD is highly prevalent in sheep and goats in the border areas of Pakistan and Afghanistan. Therefore, outbreak investigation teams should be arranged at the border level to develop FMD risk-based surveillance and control plans for small ruminants in order to mitigate infection risks.

The Pathogenesis of Foot-and-Mouth Disease Virus Infection: How the Virus Escapes from Immune Recognition and Elimination.

Foot-and-mouth disease virus (FMDV) is a highly contagious and economically devastating pathogen that affects cloven-hoofed animals worldwide. FMDV infection causes vesicular lesions in the mouth, feet, and mammary glands, as well as severe systemic symptoms such as fever, salivation, and lameness. The pathogenesis of FMDV infection involves complex interactions between the virus and the host immune system, which determine the outcome of the disease. FMDV has evolved several strategies to evade immune recognition and elimination, such as antigenic variation, receptor switching, immune suppression, and subversion of innate and adaptive responses. This review paper summarizes the current knowledge on the pathogenesis of FMDV infection and the mechanisms of immune evasion employed by the virus. It also discusses the challenges and opportunities for developing effective vaccines and therapeutics against this important animal disease.

Application of Virginia Henderson's Theory Within an Intimate Partner Violence Scenario.

The practice column focuses on incorporating a nursing theoretical framework into nursing care in a clinical scenario involving intimate partner violence. Accordingly, as exemplified by utilizing Virginia Henderson's theory, there is guidance to define, focus, and evaluate nursing care in these multifaceted clinical cases.
