AI Article Synopsis
- Histomonosis is a growing concern in turkey farming due to the absence of effective feed additives and therapeutics.
- A study analyzed 113 questionnaires from both positive and control farms in Germany to determine significant risk factors for histomonosis outbreaks.
- Key findings highlight that nearby vectors like earthworms and snails, poor biosecurity practices, and inadequate climate and litter management significantly increase outbreak risk.
Article Abstract
Histomonosis has become an important disease of turkeys since the ban of effective feed additives and therapeutics. Some critical risk factors for pathogen introduction into a farm have already been identified but open questions remain. Therefore, a retrospective case-control-study was used to identify the most significant risk factors for introduction into a turkey farm. A total of 113 questionnaires were collected from 73 control-farms and 40 -positive case-farms in Germany between 20 April 2021 and 31 January 2022. The data were analysed for possible risk factors by descriptive and univariate, single- and multi-factorial analysis. The presence of earthworms, snails and beetles, as vectors of , as well as the proximity to other poultry-keeping farms in addition to a frequent observation of wild birds nearby the turkey farm, showed the highest risk potential for histomonosis outbreaks. Furthermore, poor biosecurity measures seem to have increased the probability for an outbreak. Insufficient climate management, straw as litter material and an inadequate litter refill frequency might have promoted a favourable humidity for vector- or pathogen survival providing important areas for improved disease control measures in the future.A retrospective case-control-study was conducted to identify impactful risk factors for a introduction.The probability of a histomonosis outbreak was increased by the presence of vectors and reservoirs nearby a farm.Impactful risk factors concerning biosecurity measures, climate and litter management were identified.

The burden of pathogenic enteric protozoa and soil-transmitted helminths among impoverished populations living on the Texas-Mexico border is unclear. We conducted a cross-sectional study on an ongoing longitudinal cohort of 616 adults residing in Starr County, Texas. A total of 359 adults were screened for four protozoa and five soil-transmitted helminths by using real-time polymerase chain reaction.

With mines extending deeper and rising surface temperatures, workers are exposed to hotter environments. This study aimed to characterize heat stress and strain in the Canadian mining industry and evaluate the utility of the Heat Strain Score Index (HSSI), combined with additional self-reported adverse health outcomes. An exploratory web-based survey was conducted among workers ( = 119) in the Canadian mining industry.

Background: Despite the increasing popularity of electronic devices, the longitudinal effects of daily prolonged electronic device usage on brain health and the aging process remain unclear.
Objective: The aim of this study was to investigate the impact of the daily use of mobile phones/computers on the brain structure and the risk of neurodegenerative diseases.
Methods: We used data from the UK Biobank, a longitudinal population-based cohort study, to analyze the impact of mobile phone use duration, weekly usage time, and playing computer games on the future brain structure and the future risk of various neurodegenerative diseases, including all-cause dementia (ACD), Alzheimer disease (AD), vascular dementia (VD), all-cause parkinsonism (ACP), and Parkinson disease (PD).

Background: Low back pain (LBP) is highly prevalent and disabling, especially in agriculture sectors. However, there is a gap in LBP prevention and intervention studies in these physically demanding occupations, and to date, no studies have focused on horticulture workers. Given the challenges of implementing interventions for those working in small businesses, self-management offers an attractive and feasible option to address work-related risk factors and manage LBP.

Large language models (LLMs) are artificial intelligence tools that have the prospect of profoundly changing how we practice all aspects of medicine. Considering the incredible potential of LLMs in medicine and the interest of many health care stakeholders for implementation into routine practice, it is therefore essential that clinicians be aware of the basic risks associated with the use of these models. Namely, a significant risk associated with the use of LLMs is their potential to create hallucinations.
