Microplastics Contamination in the Edible Fish Mozambique Tilapia (Oreochromis mossambicus) from the Selvampathy Wetland of Coimbatore, Tamil Nadu, India
Bull Environ Contam Toxicol. 2023 Dec 8;112(1):7. doi: 10.1007/s00128-023-03839-w.ABSTRACTThe present study investigated the microplastics (MPs) contamination in the gastrointestinal (GI) tract, gills and muscle of the Mozambique tilapia, Oreochromis mossambicus sampled from the Selvampathy Lake of Coimbatore, Tamil Nadu. MPs abundance was found in 10 to 28, 8 to 27, and 4 to 12 particles and their size ranged between 4.4 and 210, 4.6 to 180, and 4.5 to 194 μm in the GI tract, gills and muscle, respectively. MPs were dominantly shaped as fibres (95%) and fragments (5%) with the following colour pattern of blue > black ...

Birds that lead people to honey recognize local calls from their human helpers
When people in the Niassa Special Reserve of northern Mozambique hanker for something sweet, they don’t call DoorDash or Uber Eats. They call a bird. The aptly named honeyguide will lead them to a bee nest so they can harvest the honey. The bird obtains a treat, too—scrumptious wax and bee larvae. A new study suggests this partnership, which occurs in several places in Africa, is even more intricate than scientists thought. People in different regions make unique sounds to summon the birds, and
the birds recognize and respond to calls from their local area

Mucosal and systemic immune responses after a single intranasal dose of nanoparticle and spore-based subunit vaccines in mice with pre-existing lung mycobacterial immunity
Tuberculosis (TB) is a major global health threat that claims more than one million lives annually. With a quarter of the global population harbouring latent TB, post-exposure vaccination aimed at high-risk populations that could develop active TB disease would be of great public health benefit. Mucosal vaccination is an attractive approach for a predominantly lung disease like TB because it elicits both local and systemic immunity. However, the immunological consequence of mucosal immunisation in the presence of existing lung immunity remains largely unexplored. Using a mycobacterial pre-exposure mouse model, we assessed ...

Immunogenicity of PE18, PE31, and PPE26 proteins from Mycobacterium tuberculosis in humans and mice
In this study, we explored the immunogenicity of three proteins from this family, PE18, PE31, and PPE26, in humans and mice.MethodsThe investigation involved analyzing the immunoreactivity of the selected proteins using sera from TB patients, IGRA-positive household contacts, and IGRA-negative BCG vaccinated healthy donors from the TB endemic country Mozambique. Antigen-recall responses were examined in PBMC from these groups, including the evaluation of cellular responses in healthy unexposed individuals. Moreover, systemic priming and intranasal boosting with each protein, combined with the Quil-A adjuvant, were conducte...

A probabilistic approach to compare the risk associated with heavy metals and bromine in honey from Dominican Republic, Mexico, Mozambique and Spain
This study aims to analyse the risk to consumers given the presence of heavy metals and bromine in honey from different countries. A probabilistic approach was applied to assess carcinogenic risk. Concerning exposure, Al in Spain (3.3E-04 mg/kgBw/day), B in Dominican Republic and Mexico (2E-04 mg/kgBw/day in both cases) and Fe in Mexico and Mozambique had the highest values (5E-05 and 4.8E-05 mg/kgBw/day). In risk characterisation, the values were less than 1 for hazard index (HI), meaning that the consumption of honey represents a low level of concern for non-genotoxic effects. A combination of margin of exposure and prob...

Viruses, Vol. 15, Pages 2379: Emerging Zoonotic Diseases among Pastoral Communities of Caia and B & uacute;zi Districts, Sofala, Mozambique: Evidence of Antibodies against Brucella, Leptospira, Rickettsia, and Crimean-Congo Hemorrhagic Fever Virus
Conclusions: Results from our study showed evidence of antibodies due to exposure to Brucella, Leptospira, Rickettsia, and CCHFV with antibodies against Leptospira and Rickettsia being the most prevalent. Hence, laboratory diagnosis of zoonotic diseases is essential in the early detection of outbreaks, the identification of silent transmission, and the etiology of non-febrile illness in a pastoral community. There is a need to develop public health interventions that will reduce the risk of transmission. (Source: Viruses)

IJERPH, Vol. 20, Pages 7124: Climate Change, Extreme Weather, and Intimate Partner Violence in East African Agrarian-Based Economies
©njiri
Severe weather events can be a catalyst for intimate partner violence, particularly in agricultural settings. This research explores the association between weather and violence in parts of East Africa that rely on subsistence farming. We used IPUMS-DHS data from Uganda in 2006, Zimbabwe in 2010, and Mozambique in 2011 for intimate partner violence frequency and EM-DAT data to identify weather events by region in the year of and year prior to IPUMS-DHS data collection. This work is grounded in a conceptual framework that illustrates the mechanisms through which violence increases. We used logistic regression to ...

Experiences and perceptions of urine sampling for tuberculosis testing among HIV patients: a multisite qualitative descriptive study
Conclusions
This study suggests that urine sampling is well accepted as a TB diagnostic method and provides insights on how to promote patients’ uptake of urine-based testing and improve their sampling experiences. These results encourage the future broad use of urine-based assays at point of care. (Source: BMJ Open)

In 2021 malaria caused ∼247 million clinical episodes, 2-4 million cases of severe disease and an estimated 619,000 deaths [1]. The highest mortality rates occur in sub-Saharan African children under the age of 5. The majority of the severe sequelae and deaths are due to Plasmodium falciparum. The treatment of choice fo r severe malaria (SM) in both children and adults is parenteral artesunate. However, despite this potent antimalarial, mortality rates remain high (8.5% in children and 15% in adults for SM; 18% and 30% respectively for cerebral malaria [CM]) [2,3].
