Background: Pulmonary rehabilitation(PR) is a highly effective intervention for people with chronic respiratory disease, however it not known how best to sustain its benefits. Clinical trials are needed establish if participation in Singing Lung Health(SLH) groups following PR will improve health-related quality-of-life, healthcare utilisation and exercise capacity compared usual care. A feasibility study would help guide development of these. Methods: In multi-centre, mixed-methods...
In this study, we developed a machine learning framework to detect clinical mastitis (CM) at the current milking (i.e., same milking) and predict CM next one before occurrence) quarter level. Time series quarter-level data were extracted from an automated system (AMS). For both detection prediction, best classification performance was obtained decision tree–based ensemble models. Moreover, applying models on set containing past 9 milkings showed accuracy for detecting CM; modeling with 7...
Non-aureus staphylococci and mammaliicocci (NASM) are the most frequently isolated bacterial group from bovine milk samples. Most studies focus on subclinical mastitis caused by NASM; however, NASM can cause clinical (CM) as well. We evaluated retrospective data 6 years (2017-2022) to determine species frequency of quarter CM. The was comprised microbiological results CM samples routinely submitted Quality Milk Production Services at Cornell University for microbial identification MALDI-TOF...
The purpose was to evaluate 2 intramammary treatments for mild-to-moderate cases of clinical mastitis in a noninferiority comparison. Noninferiority trials are intended show whether given treatment, hetacillin potassium, has at least comparable efficacy as the reference ceftiofur hydrochloride. Treatments can be deemed inferior treatment by an amount less than margin noninferiority, or inconclusive if confidence interval crosses noninferiority. Cows with from 6 farms were considered...
Determining the species of mycoplasma isolated from culture-positive milk samples is important for understanding clinical significance their detection. Between August 2016 and December 2019, 214,518 2,757 dairy herds were submitted to Quality Milk Production Services (QMPS) at Cornell University culture. From these samples, 3,728 collected 204 culture positive. Based on request herd managers, owners, or veterinarians, 889 isolates 98 subjected molecular identification by PCR amplicon...
The objectives were to examine the effect of an automated premilking stimulation (APS) by means a high pulsation frequency (300 cycles/min) without reduction vacuum in chamber or claw piece on (1) milking performance, (2) teat tissue condition, and (3) udder health dairy cows. In randomized controlled field study, Holstein cows (n = 427) from 1 commercial farm with schedule 3 times per day assigned treatment control groups over 90-d period. Treatments consisted maximum 80 s (APS80) 99...
Delayed milk ejection, manifested most often as bimodal flow, occurs when the cisternal fraction is removed before alveolar reaches gland cistern. It thought to be a consequence of not meeting cows' physiological needs, due insufficient premilking teat stimulation, inadequate timing milking unit attachment, or both. has been associated with decreased efficiency, reduced yield, and impaired udder health. Traditionally, portable electronic meters have used assess presence delayed ejection in...
NPs are an essential resource in the organization and creation of capacity-building efforts to improve healthcare across globe. There limited data guide effective supplementary education projects. Recent evidence highlights components sustainability, curriculum development, program evaluation.
No new antimicrobials have been approved for the treatment of mastitis since 2006; it would be beneficial to perform controlled field trials comparing 2 existing treatments. Non-inferiority are valuable in this regard, as they do not require a negative control randomized, FDA drug trial. If therapy with similar efficacy is available, decision making criteria can include convenience, lower costs, less side effects, improved delivery systems, and better integration into current protocols. The...
The sale of quarter-separated milk is prohibited under the Pasteurized Milk Ordinance; all harvested from a cow with 1 or more abnormal quarters must be discarded. However, produced by unaffected may still acceptable quality, i.e. low somatic cell count (SCC). With increasing popularity automatic milking systems (AMS) and real-time udder-level SCC monitoring, quality investigated as future technology allow for automated quarter-level testing separation. This study sought to evaluate trends...
Mastitis is the most common and costly disease of dairy cattle. It impacts farm economics through diagnostic treatment costs loss income discarded milk, decreased milk production, quality premiums. negatively affects cow comfort increases culling risk. Most cases mastitis are subclinical, leading to undetected economic losses. To mitigate these losses, surveillance for subclinical (SCM) indicators can be useful. One such indicator somatic cell count (SCC). Elevated SCC indicates...
