Article Abstract
Precision livestock farming (PLF) systems have the potential to improve animal welfare through providing a continuous picture of welfare states in real time and enabling fast interventions that benefit the current flock. However, it remains unclear whether the goal of PLF development has been to improve welfare or increase production efficiency. The aims of this systematic literature review are to provide an overview of the current state of PLF in poultry farming and investigate whether the focus of PLF research has been to improve bird welfare. The study characteristics extracted from 264 peer-reviewed publications and conference proceedings suggest that poultry PLF has received increasing attention on a global scale, but is yet to become a widespread commercial reality. PLF development has most commonly focussed on broiler farming, followed by laying hens, and mainly involves the use of sensors (environmental and wearable) and cameras. More publications had animal health and welfare than production as either one of or the only goal, suggesting that PLF development so far has focussed on improving animal health and welfare. Future work should prioritise improving the rate of commercialisation of PLF systems, so that their potential to improve bird welfare might be realised.

Association between postoperative intravenous methylprednisolone and surgical site infection in posterior lumbar fusion surgery: a retrospective single-center study.
BMC Musculoskelet Disord
December 2024
Department of Spine Surgery, The First Affiliated Hospital, Sun Yat-sen University, Guangzhou, China.
Purpose: To investigate the association between intravenous methylprednisolone administration and the risk of surgical site infection (SSI) following posterior lumbar fusion (PLF) surgery.
Methods: This retrospective, single-center study analyzed data from 800 adult patients who underwent elective PLF surgery at our institution. Patients were classified according to postoperative intravenous methylprednisolone administration.
Accuracy of diagnostic tests for perilymphatic fistula: protocol for a systematic review.
Front Neurol
November 2024
Department of Otorhinolaryngology and Head and Neck Surgery, Oslo University Hospital, Oslo, Norway.
Article Synopsis
- Perilymphatic fistula (PLF) is an inner ear condition where fluid leaks from the inner ear to the middle ear due to an abnormal connection, and early surgery may improve hearing and balance outcomes.
- The study aims to systematically review existing literature on diagnostic tests for PLF to determine their accuracy in detecting this condition in humans.
- Research will involve searching multiple databases for peer-reviewed articles, assessing the quality of the studies, and potentially synthesizing data from high-quality articles if applicable.
Ecological cooperative merging control of heterogeneous electric vehicle platoons.
PLoS One
November 2024
School of Automotive Engineering, Lanzhou Institute of Technology, Lanzhou, China.
Vehicle platooning improves energy savings via vehicle-to-vehicle (V2V) communication. Ecological cooperative adaptive cruise control (Eco-CACC) is implemented in platoons for merging task by using regrouped platoon models. The merging positions are selected in the middle and tail of an original platoon with a two-vehicle sub-platoon.

Mol Biol Rep
November 2024
Department of Respiratory and Critical Care Medicine, The First Affiliated Hospital of Zhejiang Chinese Medical University, No. 54, Youdian Road, Shangcheng District, Hangzhou, Zhejiang, 310000, China.
Article Synopsis
- Acute respiratory distress syndrome (ARDS) can lead to pulmonary fibrosis (PLF), and the study investigates the role of a specific circular RNA, hsa_circ_0006892, in these conditions.
- The research involved analyzing serum samples from 203 ARDS patients to assess the levels of hsa_circ_0006892 and its potential as a diagnostic marker, alongside understanding its interaction with the microRNA miR-486-3p.
- Findings revealed that hsa_circ_0006892 is downregulated in ARDS and PLF patients, distinguishing them from controls, and suggested that it may influence disease progression through the miR-486-3p and associated genetic pathways, particularly the Ras signaling pathway.
In Situ Expression of Yak in Mammary Glands as a Treatment for Bovine -Induced Mastitis in Mice.
Vet Sci
October 2024
College of Animal Science and Veterinary Medicine, Southwest Minzu University, Chengdu 610041, China.
Since the development of dairy farming, bovine mastitis has been a problem plaguing the whole industry, which has led to a decrease in milk production, a reduction in dairy product quality, and an increase in costs. The use of antibiotics to treat mastitis can cause a series of problems, which can bring a series of harm to the animal itself, such as the development of bacterial resistance and dramatic changes in the gut flora. However, the in vivo and in vitro antibacterial activity of yak Interleukin-22 (IL-22) and its application in mastitis caused by have not been reported.
