Egg reappearance periods of anthelmintics against equine cyathostomins: The state of play revisited.

Cyathostomins are the most common and highly prevalent parasites of horses worldwide. Historically, the control of cyathostomins has mainly relied on the routine use of anthelmintic products. Increasing reports on anthelmintic resistance (AR) in cyathostomins are concerning. A potential method proposed for detecting emerging AR in cyathostomins has been estimating the egg reappearance period (ERP). This paper reviews the data available for the ERP of cyathostomins against the three major classes of anthelmintics, macrocyclic lactones, tetrahydropyrimidines, and benzimidazoles. Published peer-reviewed original research articles were obtained from three databases (PubMed, CAB Direct and Web of Science) and were evaluated for their inclusion in a systematic review. Subsets of articles were then subjected to a review of ERP data. A total of 54 (of 134) studies published between 1972 and 2022 met the criteria for inclusion in the systematic review. Until the beginning of 2022, there was no agreed definition of the ERP; eight definitions of ERP were identified in the literature, complicating the comparison between studies. Additionally, potential risk factors for the shortening of the ERP, including previous anthelmintic use and climate, were frequently not described. Reports of shortened ERP for moxidectin and ivermectin are frequent: 20 studies that used comparable ERP definitions reported shortened moxidectin and ivermectin ERPs of 35 and 28 days, respectively. It is unclear whether the ERPs of these anthelmintics reduced to such levels are due to the development of AR or some biological factors related to horses, cyathostomin species, and/or the environment. The ERPs for other anthelmintics, such as fenbendazole and pyrantel, were frequently not reported due to established resistance against these drugs. Future research in horses is required to understand the mechanism(s) behind the shortening of ERP for cyathostomins. Based on this systematic review, we propose recommendations for future ERP studies.

Current Surgical Trainee Perceptions and Experiences in Telehealth.

Introduction:Broad expansion of telehealth technologies has been implemented during the coronavirus disease 2019 (COVID-19) pandemic to allow for physical distancing and limitation of viral transmission within health care facilities. Although telehealth has been studied for its impact on patients, payors, and practitioners, its educational impact is largely unstudied. To better understand the trainee experience and perception of telehealth during the COVID-19 pandemic, we conducted a survey of the membership of the American College of Surgeons Resident and Associate Society (RAS).Methods:An anonymous survey was sent to members of RAS. Descriptive analysis was used to report experiences and perceptions. Chi-square analysis was used to compare cohorts with and without exposure to telehealth.Results:Of the 465 RAS respondents, 292 (62.8%) reported knowledge of telehealth technologies at their institutions. The majority of these respondents experienced a decrease in in-person clinic volume (94.4%) and an associated increase in virtual clinic volume (95.7%) related to the COVID-19 pandemic. Trainee integration into telehealth workflows increased drastically from prepandemic levels (11% vs. 54.5%, p < 0.001). Likelihood of trainee exposure to telehealth was associated with university-based training programs or larger program size. Trainees demonstrated a desire for more integration and development of curricula.Conclusions:These data serve as the first description of surgical trainee experience with, and opinion of, telehealth. Trainees recognize the importance of their integration and training in telehealth. These results should be used to guide the development of workflows and curricula that integrate trainees into telemedicine clinics.

Strategies for Gait Retraining in a Collegiate Runner with Transfemoral Amputation: A Case Report.

BACKGROUND: More than fifty percent of people with limb amputations participate in sports or physical activity following amputation. Athletes with limb amputations may face additional challenges including phantom limb pain (PLP), psychological barriers, prosthetic complications, and gait abnormalities. Prevalence of PLP in the general amputee population is estimated to be as high as 85%. Despite the high prevalence of PLP, there is little research regarding the use of gait training as a treatment for PLP among both the general amputee population and athletes. CASE DESCRIPTION: A 20-year old female collegiate track and field athlete presented with phantom knee pain brought on with running. The athlete demonstrated deficits in core and hip strength as well as decreased single leg stability bilaterally. Running gait analysis revealed circumduction with the prosthesis for limb advancement and increased vaulting with push off on the sound (uninvolved) limb. Gait retraining strategies were implemented to address video analysis findings and create a more efficient running gait and address phantom limb pain symptoms. OUTCOMES: Rehabilitation and gait retraining strategies were effective in improving several clinical and functional outcomes in this case. Significant improvements were noted in PLP, running gait mechanics, and the patient's psychological and functional status as measured with a standardized outcome tool, the Patient-Reported Outcomes Measurement Information System® (PROMIS®). DISCUSSION: Running gait training following amputation could be a crucial component of rehabilitation for athletes in an attempt to lessen pain while running, especially in those experiencing phantom limb pain (PLP). Utilization of a multidisciplinary team in the gait retraining process is recommended. There is a need for further research to determine the effects of running gait retraining for management of PLP in athletes with amputation. LEVEL OF EVIDENCE: 5.

A mobility program for an inpatient acute care medical unit.

OVERVIEW: For many patients, hospitalization brings prolonged periods of bed rest, which are associated with such adverse health outcomes as increased length of stay, increased risk of falls, functional decline, and extended-care facility placement. Most studies of progressive or early mobility protocols designed to minimize these adverse effects have been geared toward specific patient populations and conducted by multidisciplinary teams in either ICUs or surgical units. Very few mobility programs have been developed for and implemented on acute care medical units. This evidence-based quality improvement project describes how a mobility program, devised for and put to use on a general medical unit in a large Midwestern academic health care system, improved patient outcomes.

Case study: positive outcomes of individualized nutritional supplementation.

The nourishment of Mrs. B, who could no longer consume enough food value from three meals a day and blended supplements, posed an ethical dilemma. Family and caregivers struggled with the fact that, while honoring the resident's rights about what and how much she chose to eat, Mrs. B. would have continued to lose weight and experience further compromise of her health. In addition, the cost of the nutritionally dense supplement placed a financial burden on the facility. Current ministry funding programs do not fund supplements for individuals like Mrs. B., who can still consume all or a portion of their meals per day, but are unable to.

Threat appraisals, distress and the development of positive life changes after September 11th in a Canadian sample.

Several surveys have reported the negative psychological impact on the general public of the terrorist attacks in the USA of September 11th, 2001. Yet the attacks also led many people to make positive changes in their relationships, values and priorities. A survey of 80 adults in Ottawa, Canada demonstrated that greater perceived threat and greater initial distress reactions significantly predicted the extent to which people reported positive changes in their lives (e.g. closer to family, refocused priorities). Initial distress and greater perceived threat also correlated positively with whether people provided help after the disaster. Follow-up data on 40 of these participants 11 months later revealed significant stability over time for the extent of positive life changes reported, and demonstrated that degree of initial distress and perceived threat continued to correlate positively with life change reports at this later point in time. The data are consistent with the argument that the perception of growth may develop out of one's personal experience of emotional pain.

Dose-dependent transcriptome changes by metal ores on a human acute lymphoblastic leukemia cell line.

The increased morbidity of childhood leukemia in Fallon, Nevada and Sierra Vista, Arizona has prompted great health concern. The main characteristic that these two towns share is the environmental pollution attributed to metal ore from abandoned mining operations. Consequently, we have investigated the transcriptome effects of metal ores from these endemic areas using a human T-cell acute lymphoblastic leukemia cell line (T-ALL). Metal ore from Fallon significantly increased cell growth after 24, 48 and 72 h of incubation at 1.5 microg/mL concentration, as measured by trypan-blue. Sierra Vista ore significantly increased cell growth with 0.15 and 1.5 microg/mL following 72 h of incubation. From human cDNA microarray, results indicate that in total, eight genes, mostly metallothionein (MT) genes, were up-regulated and 10 genes were down-regulated following treatment of the T-ALL cells with 0.15 and 1.5 microg/mL of metal ores at 72 h, in comparison with untreated cells. Twenty-eight metals of both ores were quantified and their presence may be associated with the cell growth rate and dose-dependent activation of transcriptomes in immature T-cells.
