Musculoskeletal Injury in Referees That Officiate Over Ladies Gaelic Football and Camogie

Aim Ladies Gaelic football and Camogie are leading female sports in Ireland. Referees are essential to the game, however, no research has examined injury in referees that officiate over female Gaelic games to date. Therefore, this study aims to retrospectively examine the musculoskeletal injury profile and injury prevention practices of referees that officiate over female Gaelic games. Methods A retrospective anonymous questionnaire examined injuries that occurred in the previous 12 months in currently active Ladies Gaelic football and Camogie referees (n=170). Incidence and repeat incidence proportions were calculated along with descriptive statistics. Results In 2019, 42.9% (n=73) of referees sampled sustained an injury with 27.4% (n=20) sustaining two or more. Injuries primarily occurred to the lower extremity (79.6%,n=78), particularly the lower leg (20.4%,n=20) and knee (18.4%,18). Muscle strains and cramps (55.1%,n=54) were most frequent and injuries predominantly occurred during games (71.4%,n=70). Referees largely completed a warm-up but just 30.6% (n=52) conducted a cool-down. Over half had undertaken injury prevention education but only 37.6% (n=64) incorporated injury prevention elements into their training. Conclusion Just over two in five referees that officiate female Gaelic games became injured in the previous year, however their utilisation of injury prevention strategies, beyond completing a warm-up, is lacking. Thus, a referee specific injury prevention programme should be developed and if found to be effective, incorporated into a comprehensive injury prevention strategy by the governing bodies.

Preventing Continuous Positive Airway Pressure Failure: Evidence-Based and Physiologically Sound Practices from Delivery Room to the Neonatal Intensive Care Unit

Routine use of continuous positive airway pressure (CPAP) to support preterm infants with respiratory distress is an evidenced-based strategy to decrease incidence of bronchopulmonary dysplasia. However, rates of CPAP failure remain unacceptably high in very premature neonates, who are at high risk for developing bronchopulmonary dysplasia. Using the GRADE framework to assess the quality of available evidence, this article reviews strategies aimed at decreasing CPAP failure, starting with delivery room interventions and followed through to system-based efforts in the neonatal intensive care unit. Despite best efforts, some very premature neonates fail CPAP. Also reviewed are predictors of CPAP failure in this vulnerable population.

Serotonin 2A receptor inhibition protects against the development of pulmonary hypertension and pulmonary vascular remodeling in neonatal mice

Pulmonary hypertension (PH) complicating bronchopulmonary dysplasia (BPD) worsens clinical outcomes in former preterm infants. Increased serotonin (5-hydroxytryptamine, 5-HT) signaling plays a prominent role in PH pathogenesis and progression in adults. We hypothesized that increased 5-HT signaling contributes to the pathogenesis of neonatal PH, complicating BPD and neonatal lung injury. Thus, we investigated 5-HT signaling in neonatal mice exposed to bleomycin, previously demonstrated to induce PH and alveolar simplification. Newborn wild-type mice received intraperitoneal PBS, ketanserin (1 mg/kg), bleomycin (3 U/kg) or bleomycin (3 U/kg) plus ketanserin (1 mg/kg) three times weekly for 3 wk. Following treatment with bleomycin, pulmonary expression of the rate-limiting enzyme of 5-HT synthesis, tryptophan hydroxylase-1 (Tph1), was significantly increased. Bleomycin did not affect pulmonary 5-HT 2A receptor (R) expression, but did increase pulmonary gene expression of the 5-HT 2BR and serotonin transporter. Treatment with ketanserin attenuated bleomycin-induced PH (increased RVSP and RVH) and pulmonary vascular remodeling (decreased vessel density and increased muscularization of small vessels). In addition, we found that treatment with ketanserin activated pulmonary MAPK and Akt signaling in mice exposed to bleomycin. We conclude that 5-HT signaling is increased in a murine model of neonatal PH and pharmacological inhibition of the 5-HT 2AR protects against the development of PH in neonatal lung injury. We speculate this occurs through restoration of MAPK signaling and increased Akt signaling.

Lack of EC-SOD worsens alveolar and vascular development in a neonatal mouse model of bleomycin-induced bronchopulmonary dysplasia and pulmonary hypertension

BACKGROUND

Pulmonary hypertension (PH) worsens clinical outcomes in former preterm infants with bronchopulmonary dysplasia (BPD). Oxidant stress disrupts alveolar and vascular development in models of BPD. Bleomycin causes oxidative stress and induces BPD and PAH in neonatal rats. Disruption in the vascular endothelial growth factor (VEGF) and nitric oxide signaling pathways contributes to BPD. We hypothesized that loss of EC-SOD would worsen PAH associated with BPD in a neonatal mouse model of bleomycin-induced BPD by disrupting the VEGF/NO signaling pathway.

METHODS

Neonatal wild-type mice (WT), and mice lacking EC-SOD (EC-SOD KO) received intraperitoneal bleomycin (2 units/kg) or phosphate-buffered saline (PBS) three times weekly and were evaluated at weeks 3 or 4.

RESULTS

Lack of EC-SOD impaired alveolar development and resulted in PH (elevated right ventricular systolic pressures, right ventricular hypertrophy (RVH)), decreased vessel density, and increased small vessel muscularization. Exposure to bleomycin further impaired alveolar development, worsened RVH and vascular remodeling. Lack of EC-SOD and bleomycin treatment decreased lung total and phosphorylated VEGFR2 and eNOS protein expression.

CONCLUSION

EC-SOD is critical in preserving normal lung development and loss of EC-SOD results in disrupted alveolar development, PAH and vascular remodeling at baseline, which is further worsened with bleomycin and associated with decreased activation of VEGFR2.

Maternity records in Edinburgh and Aberdeen in 1936: a comparison

Historians have long used maternity records to understand the evolution of maternity services. More recently, epidemiologists have become interested in obstetric hospital records as a source of data (e.g. birth weight, social class), to study the influence of early life on future health and disease: life course epidemiology. Edinburgh and Aberdeen are unusual in holding detailed records from several maternity institutions. The records of 1936 are of particular interest because all children born in this year and at school in Scotland at age 11 sat a cognitive ability test, the Scottish Mental Survey 1947. This study aims to describe the maternity services in Edinburgh and Aberdeen in 1936, between the First and Second World Wars. Understanding the richness of data in birth records, the manner in which they were recorded, and the context of the institutions in their community is essential for interpreting life course epidemiology studies.

Effects of contact dermatitis on hepatic gene expression in broilers

1. Severe foot and hock dermatitis in broiler chickens can reduce growth rate and increase susceptibility to bacterial infection, affecting both profitability and welfare. However, little is known about the underlying physiological changes associated with foot and hock lesions. 2. This study compared global hepatic gene expression in control birds and those with ammonia-induced foot and hock lesions using Agilent 44 K chicken oligonucleotide microarrays (8 birds per group). 3. In total, 417 genes were differentially expressed of which 174 could be mapped onto the genome. Genes associated with energy metabolism, thyroid hormone activity and cellular control were affected, while there was also evidence of an up-regulation of genes linked to a pro-inflammatory response. 4. It is conceivable that pain is the underlying cause for the observed changes in energy metabolism genes. 5. Changes in hepatic gene expression provide new information on how a chicken's physiological mechanisms alter to cope with foot and hock lesions. The findings support other data indicating that birds with increased severity of lesions are likely to be in pain and that growth will be compromised. Reduction of the incidence of dermatitis by improved husbandry should therefore benefit both welfare and commercial performance.

Dementia and the nursing home: association with care needs

OBJECTIVE

To determine whether RUG reimbursement categories accurately predict requirements for care in nursing homes.

DESIGN

Prospective descriptive study of residents in lower reimbursement categories according to RUG.

SETTING

Three nursing homes in New York City.

PARTICIPANTS

Convenience sample of 173 residents who agreed to participate, not significantly different from 201 who did not agree to participate.

MAIN MEASURES

Chart review; assessment of residents' cognitive and functional abilities; nursing assistants' ratings of residents' functional abilities, behavioral problems, the amount of effort required in care; and time-motion studies of staff-resident interactions.

RESULTS

Both the residents' RUG classification (P less than 0.01) and the level of ADL independence (P less than 0.001) had significant impacts on the staff effort required in their care, with more dependent residents requiring greater effort. The residents' level of cognitive impairment also had a significant impact on the staff effort, with the severely impaired requiring greater effort (P less than 0.05). The time-motion analysis indicated that residents within the same RUG category differed in the number of staff-resident interactions based on their level of cognitive impairment.

CONCLUSIONS

Cognitive impairment is a significant morbidity (or co-morbidity) in determining the quantity of staff effort required by the resident, and behavioral interventions are an important care component. There is marked heterogeneity within lower (RUG) reimbursement categories which translates into strikingly different care requirements.

Perception of alcohol use and misuse in three ethnic communities: implications for prevention programming

This article compares data about perceptions of alcohol use and misuse, including perceived patterns of use, extent of the problem, reasons for use, and causes and effects of alcohol misuse in the Chinese, Indo-Pakistani, and Latin American communities in British Columbia. The methodology employed is an adaptation of Neuber's Community Needs Assessment model, using data from three sources: (1) relevant literature, (2) interviews with designated key informants, and (3) interviews with selected potential program consumers within the community. This article focuses on data gathered from potential program consumers. Results indicate that alcohol-related problems are considered least serious and widespread in the Chinese community and considerably more serious in the Latin American and Indo-Pakistani communities. Family difficulties present themselves in all communities as both possible causes and major consequences of alcohol misuse. Finally, implications for developing culturally responsive prevention programs are drawn.

Clinical comparison of the threshold-related and single-intensity strategies of the Humphrey Field Analyzer

The threshold-related, eccentricity-compensated strategy was compared to the single-intensity strategy using a minimal test point distribution. Forty-two eyes known to be free of any visual field defect and 44 eyes with documented defects were tested with each screening strategy. The threshold-related, eccentricity-compensated strategy yielded a slightly poorer sensitivity (84.4%) and specificity (97.6%) than the single-intensity sensitivity (90.9%) and specificity (100%). An explanation for this decreased sensitivity is offered. The 40-point test was useful for some general screening. Recommendations are made for appropriate utilization and interpretation.
