AI Article Synopsis
- A study examined a pathogen affecting turkeys linked to lower hatchability and leg issues, with its prevalence declining over time.
- Researchers conducted a retrospective analysis of 101 deceased turkeys in Italy from 2011 to 2012, discovering that over 55% tested positive for the pathogen.
- The study found a strong correlation between the pathogen and skeletal abnormalities, suggesting that this pathogen should be considered in diagnoses of turkeys with leg deformities.
Article Abstract
, a pathogen affecting the turkey industry, is commonly associated with decreased hatchability and leg abnormalities in young progeny. This was in the spotlight more in the past than today since its prevalence has been decreasing over time. Reports of in turkeys showing reduced growth performances, leg problems and skeletal abnormalities are scarce although there is no report whether this pathogen has been completely eradicated in commercial turkeys. Additionally, there are no comprehensive epidemiological data available on prevalence in any country. Therefore, we carried out a retrospective study to evaluate the prevalence of the infection and any correlation between necropsy findings and presence in Italian turkeys between 2011 and 2012. Necropsy was performed on 101 dead turkey submissions presented for diagnostic purposes. Fifty-six submissions (55.4%) tested positive for , most of which (69.6%) were between 4 and 7 weeks of age. Skeletal abnormalities were observed in 36 cases (35.6%). The logistic regression analysis revealed that the probability of finding a -positive submission was four times higher if the animals showed skeletal abnormalities (OR = 4.48, IC 95%: 1.66-12.15). This is the first retrospective, cross-sectional study on field outbreaks in commercial turkeys. These results suggest that should be considered as a differential diagnosis when skeletal abnormalities are observed. RESEARCH HIGHLIGHTS was found in more than half of the turkey groups analysed. was likely to be detected if skeletal abnormalities were present in the studied turkeys.

Comparison of stop-jump muscle synergies in amateur basketball players with and without asymptomatic patellar tendon abnormalities during simulated games.

: Asymptomatic patellar tendon abnormality (APTA) is considered a precursor to patellar tendinopathy (PT), but its pathogenesis remains unclear, especially regarding changes in muscle coordination. Therefore, it is essential to explore the muscle synergy patterns in individuals with APTA. This study recorded sEMG data during stop-jump tasks in 8 APTA and 8 healthy amateur male basketball players in a simulated basketball game.

Variations of the ankle anatomy are infrequent and exist as supernumerary muscles and tendons. Often understudied and overlooked, their presence can cause many complications of the lower extremity. These muscles, although often asymptomatic, can cause great pain and complications such as tenosynovitis, tarsal tunnel syndrome, lateral ankle instability, and ankle pain when they impinge on the normal anatomy of the patient.

Motor neurons (MNs) within the nucleus ambiguus innervate the skeletal muscles of the larynx, pharynx and oesophagus, which are essential for swallow. Disordered swallow (dysphagia) is a serious problem in elderly humans, increasing the risk of aspiration, a key contributor to mortality. Despite this importance, very little is known about the pathophysiology of ageing dysphagia and the relative importance of frank muscle weakness compared to timing/activation abnormalities.

Summary: Short stature is a common complaint among pediatric visits and the differential diagnosis is extensive. Although some variations in growth are normal, deviation from normal growth is often the first symptom of chronic disease in children. This is true for hormone abnormalities including growth hormone deficiency, hypothyroidism and glucocorticoid excess.

Alagille syndrome (ALGS) is a multisystem autosomal dominant disorder in which patients may have characteristic facial features and involvement of the liver, heart, vessels, bones, eyes, kidneys and central nervous system. As there is little published data on ALGS in Africa, our aim was to describe the presentation and outcomes of ALGS in South Africa. The study constitutes a retrospective analysis of 25 patient medical records diagnosed as ALGS at Chris Hani Baragwanath Academic Hospital Pediatric Gastroenterology clinic between January 1992 and January 2020.
