An experiment was undertaken to examine the effect of rapid pH fall at a high muscle temperature on meat and eating quality of two beef cuts (striploin and cube roll). From 115 beef steer carcasses of which the right side of each carcass was subjected to electrical stimulation, 25 carcasses which exhibited the largest difference in the rate of pH fall in the M. longissimus between sides were selected for subsequent sampling. All of the stimulated sides missed the ‘ideal’ pH/temperature window (defined as temperature at pH 6 in the M. longissimus <35°C and >12°C) at the upper end, as did several of the non-stimulated sides. The mean temperature at pH 6 for stimulated sides from modelling was 40.9 versus 33.3°C for non-stimulated sides. Despite the significant effect of stimulation on pH decline there was no statistically significant impact on shear force or sensory traits of the M. longissimus, but there was a significant effect of aging on these traits. There was no effect of stimulation or pH decline on drip loss of the striploin. After 14 days of aging there was no effect of stimulation or ultimate pH on striploin purge, but there was a significant effect of pH decline. This was not, however, evident for purge of the cube roll aged for either 4 or 42 days. The redness of the cube rolls as reflected by a* values declined with days of display, with the decline more rapid for samples aged for 42 days compared with those aged for 4 days. For meat aged and displayed identically, the a* values were on average significantly lower for meat from non-stimulated carcasses, but apart from aging there was no effect on the wavelength ratio 630/580 nm, an indicator of the formation of metmyoglobin. There was also evidence that a rapid decline in pH increased the onset of lipid oxidation.

This study aimed to assess the effectiveness of a novel chest compression (CC) smart-ring-based feedback system in a manikin simulation. In this randomized, crossover, controlled study, we evaluated the effect of smart-ring CC feedback on cardiopulmonary resuscitation (CPR). The learnability and usability of the tool were evaluated with the System Usability Scale (SUS). Participants were divided into two groups and each performed CCs with and without feedback 2 weeks apart, using different orders. The primary outcome was compression depth; the proportion of accurate-depth (5–6 cm) CCs, CC rate, and the proportion of complete CCs (≤1 cm of residual leaning) were assessed additionally. The feedback group and the non-feedback group showed significant differences in compression depth (52.1 (46.3–54.8) vs. 47.1 (40.5–49.9) mm, p = 0.021). The proportion of accurate-depth CCs was significantly higher in the interventional than in the control condition (88.7 (30.0–99.1) vs. 22.6 (0.0–58.5%), p = 0.033). The mean SUS score was 83.9 ± 8.7 points. The acceptability ranges were ‘acceptable’, and the adjective rating was ‘excellent’. CCs with smart-ring feedback could help achieve the ideal range of depth during CPR. The smart-ring may be a valuable source of CPR feedback.

Background and Aim: Pre-slaughter management and slaughter operations are considered critical factors for animal welfare and meat quality. Previous studies have found poor animal welfare management at municipal slaughterhouses in Ecuador, and little is known about how this affects the microbiological quality of the meat. Therefore, the aim of the study was to analyze the association of the microbiological quality of beef carcasses and animal welfare indicators in a municipal slaughterhouse in Ecuador. Materials and Methods: Data for 6 months were collected from a municipal slaughterhouse in Ecuador. Five trained researchers were strategically located along the slaughter process. A total of 351 animals were observed with regard to welfare indicators, and their carcasses were sampled to evaluate microbiological quality. Antemortem (slipping, falling, and vocalization) and postmortem animal welfare indicators (bleed interval, pH, temperature, and bruises) were measured. To determine the total aerobic bacteria (TAB) and Escherichia coli counts and the presence of Salmonella spp., we collected samples by swabbing four different points of each carcass. The association between microbiological quality and animal welfare indicators was studied using univariate and multivariate logistic regressions. Results: The mean TAB count was 5.3 log CFU/cm2, and the mean total count of E. coli was 2.4 log CFU/cm2. Salmonella spp. were isolated in 3.1% of the carcasses. An electric goad was used in all animals, 19.1% slipped at least once, and 19.9% vocalized. The mean pH of the carcasses was 7.2, and 79.2% of carcasses had bruises. Multivariate analysis showed that Salmonella spp. and the TAB count were associated with pH and the number of bruises (p = 0.01 in both cases). Conclusion: Although there was non-significant association between the majority of animal welfare indicators and microbiological quality, the poor management affecting animal welfare and carcass hygiene are worrisome.

Rate Of Cooling

A previous investigation, reported at the Winter Meeting 1985, showed significant effects of growth promoters on carcass composition and on the eating quality of sirloin steaks. The growth promoters investigated factorially were (a) hormonal implants (heifers, Zeranol; steers, Zeranol + Trembolone acetate), (b) feed additive (Avotan) and (c) fishmeal. The experiment was repeated during the winter of 1984/85, with the eating quality investigation expanded to cover some 192 households, using sirloin steaks from all 64 cattle involved in the investigation. In addition, the rate of carcass cooling in the left-hand side of each animal was measured using electronic probe thermometers placed in the longissimus dorsi immediately after slaughter. This data was used to test the hypothesis that rate of carcass cooling was negatively related to the fat content of the carcass and with overall eating quality due to the effects of cold shortening.

Purpose Employees are being forced to retreat to their home offices for remote working during the Covid-19 crisis, while employers are left wondering what the scattering of their workforces would do to collaboration, accountability and visibility across their organizations and whether it would give rise to the operational siloes and data fiefdoms that they had been bent on dismantling? At the epicenter of the pandemic, just the opposite was happening in the unlikeliest of places: a health-care operation in New York City. In a profession known for monolithic silos, at least one company was demonstrating how eliminating siloes can heighten collaboration, increase efficiency and ultimately yield better outcomes. Design/methodology/approach Businesses can promote visibility, the free flow of information and collaboration across an enterprise, while keeping siloes from creeping back into the organization looking at resource management, assessment of the quality of your data, along with ERP capabilities and alignment around project-specific and overarching strategic goals. Findings Four steps include defining the KPIs that will help drive your strategy – project-based and enterprise/portfolio-wide – using both internal and external benchmarks, looking for trends in the data and diving deeper. Once these practices and processes become the norm across an organization, the siloes that erode productivity and efficiency should start to crumble, and your real-world outcomes should begin to look a lot more like the ideal-world outcomes that you have been striving for. Then you will know your ERP upgrade has been worthwhile. Originality/value To select the right integrated tool for your organization, there are seven questions to ask, such as what is the architecture of the software? Is the software company you are buying from customer-focused? Will using the system properly yield cost savings for the organization?

The third national baseline microbiological survey of Australian beef carcasses and frozen boneless beef was conducted in 2004. Carcasses (n = 1,155) sampled at 27 slaughter establishments had a mean aerobic plate count (at 25°C) of 1.3 log CFU/cm2. Escherichia coli was isolated from 8.0% of the carcasses, with a mean count of −0.8 log CFU/cm2 for positive samples. On samples from 24 boning (fabrication) plants (n = 1,082), the mean aerobic plate count for frozen boneless beef was 1.3 log CFU/g, and the mean count for the 1.8% of samples with detectable E. coli was 1.5 log CFU/g. E. coli O157: H7 was isolated from 1 of 1,143 carcasses and from 0 of 1,082 boneless samples. Salmonella was isolated from 0 of 1,155 carcasses and from 1 of 1,082 samples of boneless product. No Campylobacter spp. were isolated from carcasses or boneless beef. Coagulase-positive staphylococci were isolated from 28.7% of beef carcasses and 20.3% of boneless beef samples, and positive samples had a mean count of 0.3 log CFU/cm2 and 0.8 log CFU/g, respectively.

ABSTRACTCarcass and meat composition and eating quality of m. longissimus lumborum (LI) and leg joints were compared in entire male (ram), castrated male (wether) and female (ewe) Dorset Down-cross and Suffolk-cross lambs at about 20 weeks old. Rams grew faster than wethers and ewes particularly in the earlier maturing Suffolk crosses. Carcass weights ranged from 13 to 24 kg and at the mean carcass weight of 17·7 kg ram carcasses yielded larger shoulder joints. Ram carcasses were assessed visually leaner than those from the other sexes with similar conformation scores. Dorset Down carcasses tended to be fatter than Suffolk carcasses and the leanest carcasses were from Suffolk rams. Intramuscular fatness in LI was similar in all sexes. Intramuscular collagen contents were higher in ram LI than in other sexes. There were no differences in protein content, pH or colour of raw or roast LI. In assessments of eating quality of LI by triangle tests, male and female assessors differentiated twin rams and wethers equally. Category scaling showed LI from ewes to be slightly tougher than those from rams and wethers. Consumer evaluation of leg joints did not detect any differences in odour due to sex and ram meat was assessed better than that from wethers or ewes.

To standardize the assessment of the hygienic quality of beef carcasses in Northern Ireland (NI) abattoirs, swabbing techniques were evaluated. Six materials, including two commercially produced swabs, were compared for their ability to recover spoilage and pathogenic bacteria and for their ease of use as carcass swabs. A sponge retailed for domestic use was selected on the basis of efficiency of recovery of microorganisms, ease of use, and cost. On sample carcasses, 1,000 cm2 of the brisket was swabbed, since this site is normally readily contaminated. For 9 months, 420 carcasses in seven of the nine European Union–approved abattoirs in NI were sampled while in the chiller (24 to 48 h after kill). Total viable count (TVC), yeasts and molds, and Enterobacteriaceae were enumerated after incubation at 22 (48 h) and 37°C (48 h), and the results were expressed as log CFU/cm2. The mean TVC results at 22 and 37°C were 2.80 ± 0.70 and 2.75 ± 0.64, respectively. Although 63% of samples had yeasts that grew at 22°C, only 35% were positive at 37°C. The respective mean yeast counts were 1.12 ± 0.59 and 0.46 ± 0.51. Enterobacteriaceae were present in 15% of samples at 22°C and 21% of samples at 37°C. The mean counts for positive samples were 0.41 ± 0.37 and 0.40 ± 0.30, respectively. Molds were found in less than 4% of samples. Given that the brisket is normally one of the most heavily contaminated parts of the carcass, these results suggest that good hygienic practices are in operation in NI abattoirs. The results also enabled the abattoirs with the cleanest carcasses to be identified, hence permitting best practices to be found.

Individuals with ocular and oculocutaneous albinism (OCA) have significantly reduced visual acuity (VA) resulting in visual impairment (VI). The aim is to report on the visual function of adolescents with OCA and their quality of life (QoL) in terms of their visual ability. A total of 28 adolescents with OCA participated in this study. Tests of visual function included distance VA, refractive error, contrast sensitivity (CS), and colour vision. The Cardiff Visual Ability Questionnaire for Children (CVAQC) was used to assess visual ability. All participants presented with cutaneous hypopigmentation and nystagmus, while only two had strabismus. A mean myopic refractive error was found, and with-the-rule (WTR) astigmatism was most common. The mean best-corrected VA was 0.81 ± 0.17 logMAR and 0.81 ± 0.18 logMAR in the right and left eyes, respectively. The mean CS with the best refractive correction was 1.23 ± 0.33 log CS in the right eye and 1.29 ± 0.33 log CS in the left eye. The mean Cardiff visual ability score was −0.37 ± 0.79 log units. The variation of refractive errors and the magnitude thereof underscores the need for regular eye examinations in individuals with OCA. The majority of participants had moderate VI, and these participants had a better mean Cardiff visual ability score than those with severe VI. Similarly, participants with normal binocular CS had a better Cardiff visual ability score than those with a loss of CS.

Objectives (1) To assess outcomes in children undergoing adenoidectomy for the treatment of mild obstructive sleep apnea (OSA). (2) To identify clinical factors that predict which children will have persistent obstruction following adenoidectomy. Study Design Case series with chart review over a 10-year period. Setting Tertiary children’s hospital. Subjects and Methods Children between 2 and 17 years old undergoing adenoidectomy for treatment of mild OSA (obstructive apnea-hypopnea index [AHI] between 1 and 5 on polysomnogram) were included. The need for additional medical or surgical intervention following adenoidectomy was recorded. When available, postoperative polysomnogram data were reviewed. Results In total, 134 children with a mean age of 5.4 years were included. Fifty-three percent (n = 71) were female and 57% (n = 76) were black. The mean (SD) baseline AHI was 2.2 (1.09). Caregivers reported a moderate impact of sleep disturbance on quality of life with a mean (SD) preoperative total OSA–18 score of 64.1 (19.28). Postadenoidectomy outcomes were reported for 105 patients (78%) with a mean follow-up time of 6 months. Sixty-nine percent (n = 72) of children had resolution of obstructive symptoms. While 31% (n = 33) of children required additional intervention following adenoidectomy, only 6.8% (n = 9) underwent a subsequent tonsillectomy. Demographic factors such as age and baseline AHI did not predict which children required additional treatment following adenoidectomy. Conclusion Adenoidectomy may be an effective treatment for mild OSA. A randomized trial comparing outcomes for adenoidectomy and adenotonsillectomy is needed to determine the ideal surgical treatment for nonsevere OSA in children.

Objective: To investigate the safety and efficacy of a vascular prop device for laparoscopic orthotopic kidney transplantation (LOKT) in swine.Material and Methods: Twenty swine were randomly divided into two groups. A vascular prop device was used in the observation (VP) group, and the vein beltization technique was used in the control (VB) group. The right kidney, as a donor graft, was laparoscopically transplanted to the location of the left kidney after a left nephrectomy. Data on the operative time, venous anastomotic time, vein stenosis, etc., and the survival of the swine in the two groups were recorded.Results: The mean transplant operative time, the mean cold ischemia time, and the venous anastomotic times in the VP group were significantly shorter than those in the VB group. Seven swine in the VP group and three swine in the VB group survived for 7 days. Autopsy results showed the occurrence of one artery stenosis and one vein stenosis in the VP group and one artery stenosis and five vein stenoses in the VB group. The median survival time was 6.25 days for the swine in the VP group and 4.40 days for those in the VB group.Conclusions: The vascular prop device is safe and feasible for LOKT in swine and may accelerate venous anastomosis and ensure the quality of venous anastomotic stoma.
