Summary: The study demonstrates that vaccinating pigs against influenza can significantly reduce the risk of influenza virus transmission. Observations on pigs vaccinated with live-attenuated influenza virus or killed influenza virus, as well as corresponding ferret exposure groups, show improved outcomes on both sides of the interface. Pigs vaccinated with live-attenuated virus also show a significant delay in onset of infection among exposed ferrets.

Summary: The study found that influenza A viruses are likely highly prevalent in South African swine farms, with male workers aged 23-32, who reported recent exposure to influenza patients and infrequent use of personal protective equipment being at highest risk of molecular detection of influenza A virus. Periodic surveillance for novel influenza viruses in swine farms and education/seasonal influenza vaccine programmes for swine workers would be beneficial in South Africa.

Summary: The study revealed suboptimal adherence to influenza vaccination among Mexican HCWs and factors associated with vaccine receipt were similar to those reported in other studies, including incremental doses received in the past and awareness of vaccination campaigns. Lack of information and poor communication were identified as barriers by both vaccinated and unvaccinated personnel.

Summary: The study revealed that adolescents born between 2004 and 2013 may be more susceptible to infection with H3 subtype-related IAV-S. Over time, the expansion of existing immunologic gaps could increase the likelihood of future IAV-S spillover to humans, leading to disease outbreaks with pandemic potential.

Summary: Research indicates that swine jackpot shows play a significant role in the transmission of influenza zoonoses, with a higher detection rate of influenza among pigs at these events. Additionally, it is shown that influenza primarily spreads at county fairs, as a larger number of influenza-positive pigs are detected at these events.

Summary: This study aimed to explore the prevalence of avian influenza virus (AIV) in rural and peri-urban live bird markets (LBMs) in Bangladesh and identify associated risk factors. The results showed that the cleanliness and biosecurity measures in rural and peri-urban LBMs were significantly poor, leading to a high prevalence of AIV in Bangladeshi LBMs. Therefore, it is recommended to enhance surveillance and biosecurity practices in live bird markets in rural and peri-urban areas of Bangladesh to prevent the transmission of AIV to humans and wild birds.

Summary: In 2019, a case of bidirectional infection between humans and pigs occurred in a swine farm in Japan. An employee with influenza-like illness transmitted the infection to sows, which subsequently infected a veterinarian and her family. Whole-genome analysis confirmed that the viruses isolated from all individuals belonged to the same lineage. Unique mutations in the influenza A virus genomes corresponding to the host species were also identified.

Summary: This study investigates the psychosocial risk factors of Mexican workers. The research is conducted in five work centers with 1458 workers, finding that workload, lack of control over work, and workday are the factors with medium, high, and very high-risk levels. The study also evaluates the reliability and validity aspects of the Reference Guide III (RGIII), showing that RGIII has sufficient internal consistency but lacks a clear factorial structure.

Summary: This paper presents the results of swIAV surveillance in Danish swine from 2011 to 2018, revealing multiple different circulating genotypes of the virus, including novel reassortants with human seasonal IAV gene segments. The phylogenetic analysis showed genetic drift in antigenic sites of the hemagglutinin protein and identified a swine divergent cluster among the viruses studied.

Summary: Biosecurity measures in ruminant livestock farming vary among individual farms in terms of implementation frequency. This study evaluated the usage of biosecurity measures by farmers and identified factors influencing their decisions. The most commonly used measures were tick control, vaccination, and isolation of sick animals. Factors such as farm size, animal species, and land ownership were associated with the frequency of biosecurity measure implementation.

Summary: This systematic review and meta-analysis examined the prevalence and seroprevalence of swine influenza A viruses (swIAV) in South Korean domestic pigs and identified important risk factors. The overall prevalence and seroprevalence in domestic pigs were 0.05 and 0.35, respectively. Publication year and sample size were significantly associated with heterogeneity, and there was a significant non-linear association between swIAV prevalence and seroprevalence and specific growth stages of pigs. Regular monitoring of pigs at different growth stages may help minimize the risk of a pandemic.

Summary: The study aimed to estimate the circulation of influenza A viruses and characterize the strains at the interface between swine workers and their animals in Nigeria, a hub for pig production in Africa. The results showed that a significant number of pig serum samples had anti-influenza A antibodies, indicating circulation of the virus in pigs. However, no positive results were found in pig swabs. Two strains of influenza A, A(H1N1)pdm09 and seasonal A(H3N2), were detected in swine workers. The study emphasizes the importance of raising awareness among swine workers and implementing vaccination and other preventive measures to reduce inter-species transmission.

Summary: The study demonstrates that open-field mass-releases of wAlbB-infected Ae. aegypti males can significantly reduce natural populations of Ae. aegypti in urbanized settings in south Mexico, with efficacy reaching up to 89.4% at six months after the initiation of the suppression phase. This successful pilot integration of Wolbachia IIT-SIT within an Integrated Vector Management plan led by the Mexican Ministry of Health personnel marks a significant advancement in the control of Ae. aegypti populations.

Summary: This study aimed to describe the specific IgG antibody responses to the receptor-binding domain (RBD) and full-length spike (S) of SARS-CoV-2 after vaccination with two different vaccine preparations. The results showed that both vaccine preparations induced detectable levels of IgG against the RBD or Spike in both naive and SARS-CoV-2 pre-exposed vaccinees. Antibodies against the nucleocapsid (N) protein were also detected in some vaccine recipients without a history of COVID-19 infection.

Summary: The incidence of anal intraepithelial neoplasias associated with HPV is increasing worldwide, with higher risk among individuals living with HIV/AIDS. A study in Mexico found that 59.8% of men and women living with HIV had anal HPV infection, with multiple genotypes identified. Risky behaviors, such as receptive anal intercourse and inconsistent condom use, were associated with HPV infection. Cytology identified low-grade and high-grade squamous intraepithelial lesions in a significant proportion of participants.

Summary: Respiratory viruses, including the novel SARS-CoV-2 responsible for the COVID-19 pandemic, pose a major global public health problem. Current antiviral drugs for influenza and respiratory syncytial virus have limitations and side effects. This review highlights the potential of quinones, both natural and synthetic, as promising alternatives for the pharmacological treatment of viral respiratory infections, with their interesting biological activities against respiratory viruses.

Summary: This study analyzes the combination of two SARS-CoV-2 viral antigens and finds that immunization with a combination of S1 or RBD and the N protein can elicit a stronger immune response. The sera from immunized mice can recognize different variants of SARS-CoV-2. This study identifies potential antigens for the second generation of COVID-19 vaccines.

Summary: This study found that body fat percentage and fat mass index were positively associated with C-reactive protein (CRP) levels in female breast cancer survivors, while appendicular skeletal lean mass index (ASMI) decreased as CRP levels increased. Interleukin 6 (IL-6) was positively associated with fat mass index. Interventions to improve body composition in breast cancer survivors should consider the role of inflammatory markers to avoid sarcopenic obesity and the risk of recurrence.
