Background: Epidemiological studies have linked morbidity and mortality of individuals to exposure to atmospheric gaseous and particulate matter especially fine particles (PM2.5) and coarse particles (PM10).The process of garri (cassava crisps) production (frying with firewood) is associated with production of gaseous and particulate matter which contribute to ambient particulate matter air pollution. The objective of this study was to determine the impact of air quality indices on the prevalence of respiratory symptoms among the garri processing workers in Ogbomoso.
Methodology: A comparative cross-sectional study was carried out among 351 garri processing workers in Ogbomoso as subjects and 351 residents of Ogbomoso metropolis as controls that were age, sex and height-matched. A semi-structured questionnaire was used to obtain sociodemographic profiles and respiratory symptoms of participants and document physical examination findings. Particulate matter counter was used for air quality sampling.
Results: The mean age of subjects was 41.7 ± 14.9 years and that of controls was 41.6 ± 14.7 years (p =0.960). The two groups were also matched for socioeconomic status, sex and height. Prevalence of respiratory symptoms was higher at 48.4% among the garri workers than the control group which was 29.1% (p<0.001). Cough was the predominant symptom with a prevalence of 29.3% and 10.5% among the subjects and controls respectively. The mean count of PM1.0 in garri processing locations was significantly higher than that recorded in Ogbomoso metropolis; 73.77±42.08 vs 15.04±6.66mg/m3 (p<0.0001).
Conclusion: Garri processing work is associated with significant increase in ambient air pollution and increased prevalence of respiratory symptoms among the workforce compared to the control population. Effective preventive strategies including education and provision of safety masks may reduce the occupational hazards associated with garri processing factory workers in Nigeria.

Up to 50-70% of patients with liver cirrhosis develop hepatic encephalopathy (HE), which is closely related to gut microbiota dysbiosis, with an unclear mechanism. Here, by constructing gut-brain modules to assess bacterial neurotoxins from metagenomic datasets, we found that phenylalanine decarboxylase (PDC) genes, mainly from Ruminococcus gnavus, increased approximately tenfold in patients with cirrhosis and higher in patients with HE. Cirrhotic, not healthy, mice colonized with R.

Background: Respirator failure (RF) is a severe malignant complication in both lateral medullary infarction (LMI) and medial medullary infarction (MMI) patients. However, the differences in clinical and radiological manifestations associated with RF between patients with LMI and MMI have not been fully elucidated.
Methods: A total of 435 consecutive patients with MI within 7 days of onset in our institute were retrospectively enrolled from January 2017 to January 2024.

Current strategies for improving energy supply in hypobaric hypoxic environments are limited. Therefore, this study investigates the effects of four carbohydrates with different levels of digestibility on energy metabolism in vivo in hypobaric hypoxic environments. First, we characterized the four types of carbohydrates.

Bovine herpesvirus type 1 (BoHV-1) is a widespread respiratory infection that significantly impacts cattle health worldwide. To address this issue in China, we previously developed a novel double gene-deleted vaccine targeting gG and tk. In this study, we further evaluated the efficacy of this vaccine by challenging vaccinated cattle with a prevalent wild-type BoHV-1 strain and comparing its effectiveness against a commercially available inactivated BoHV-1 vaccine.
