ABSTRACT

AIMS: To explore the practice effect of establishing an integrated treatment process by stroke emergency nurses in general hospitals for acute ischaemic stroke (AIS).

DESIGN: Compared the time spent in each link before and after the establishment of AIS integrated treatment.

METHODS: Since March 2016, we set up a team of emergency stroke nurses (ESN), trained and assessed the knowledge of emergency stroke, and set up a post of ESN.

RESULTS: The median time of admission-judgement, admission-establishment of venous access, admission-cranial CT examination and admission-intravenous thrombolytic therapy was statistically significantly shortened after the implementation of the integrated treatment process of AIS coordinated by stroke emergency nurses (p < .01). The new treatment process of AIS further shortens the time of each treatment link and promotes the timeliness.

ABSTRACT

AIM: Interleukin (IL)-1 receptor like-1, encoded by the IL1RL1 gene, is a receptor for IL-33. In European birth cohorts, IL1RL1 rs102082293, rs10204137 (rs4988955), rs13424006 and rs13431828 (rs13048661) variations were associated with asthma at school age. In a Dutch multi-center study, IL1RL1 rs1921622 variation was associated with severe bronchiolitis. We evaluated the associations of these five IL1RL1 variations with asthma and lung function at school age after hospitalisation for bronchiolitis in infancy.

METHODS: Follow-up data, including impulse oscillometry at age 5-7 and flow-volume spirometry at age 11-13 years, and the IL1RL1 genotype data were available for 141 children followed until 5-7 and for 125 children followed until 11-13 age years after bronchiolitis in infancy. The IL1RL1 rs10204137 and rs4988955, and the IL1RL1 rs13048661 and rs13431828, are 100% co-segregating in the Finnish population.

RESULTS: The variant IL1RL1 rs13048661/13431828 genotype was constantly associated with increased asthma risk by various definitions at 5-7 and 11-13 years of ages. The result was confirmed with analyses adjusted for current confounders and early-life environment-related factors. Statistical significances were lost, when maternal asthma and atopic dermatitis in infancy were included in the model.

CONCLUSION: IL1RL1 rs13048661/13431828 variation was associated with post-bronchiolitis asthma outcomes at school age.

ABSTRACT

Impaired apoptosis is one of the hallmarks of cancer, and almost all of the non-surgical approaches of eradicating tumour cells somehow promote induction of apoptosis. Indeed, numerous studies have stated that non-ionizing non-thermal extremely low-frequency magnetic fields (ELF-MF) can modulate the induction of apoptosis in exposed cells; however, much controversy exists in observations. When cells are exposed to ELF-EMF alone, very low or no statistically significant changes in apoptosis are observed. Contrarily, exposure to ELF-EMF in the presence of a co-stressor, including a chemotherapeutic agent or ionizing radiation, can either potentiate or inhibit apoptotic effects of the co-stressor. In our idea, the main point neglected in interpreting these discrepancies is “the cellular stress responses” of cells following ELF-EMF exposure and its interplay with apoptosis. The main purpose of the current review was to outline the triangle of ELF-EMF, the cellular stress response of cells and apoptosis and to interpret and unify discrepancies in results based on it. Therefore, initially, we will describe studies performed on identifying the effect of ELF-EMF on induction/inhibition of apoptosis and enumerate proposed pathways through which ELF-EMF exposure may affect apoptosis; then, we will explain cellular stress response and cues for its induction in response to ELF-EMF exposure; and finally, we will explain why such controversies have been observed by different investigators.

ABSTRACT

Approximately counting and sampling knowledge states from a knowledge space is a problem that is of interest for both applied and theoretical reasons. However, many knowledge spaces used in practice are far too large for standard statistical counting and estimation techniques to be useful. Thus, in this work we use an alternative technique for counting and sampling knowledge states from a knowledge space. This technique is based on a procedure variously known as subset simulation, the Holmes-Diaconis-Ross method, or multilevel splitting. We make extensive use of Markov chain Monte Carlo methods and, in particular, Gibbs sampling, and we analyse and test the accuracy of our results in numerical experiments.

ABSTRACT

BACKGROUND: Maternal obstetric morbidity is a growing concern in the USA, where rates of maternal morbidity exceed Europe and most developed countries. Prior studies have found that obstetric case volume affects maternal morbidity, with low-volume facilities having higher rates of morbidity. However, these studies were done in civilian healthcare systems that are different from the Military Health System (MHS). This study evaluates whether obstetric case volume impacts severe maternal morbidity (SMM) in military hospitals located in the continental United States.

METHODS: This cross-sectional study included all military treatment facilities (MTFs) (n = 35) that performed obstetric deliveries (n = 102,959) from October 2015 to September 2018. Data were collected from the MHS Data Repository and identified all deliveries for the study time period. Severe maternal morbidity was defined by the Centers for Disease Control. The 30-day readmission rates were also included in analysis. Military treatment facilities were separated into volume quartiles for analysis. Univariate logistic regressions were performed to determine the impact of MTF delivery volume on the probability of SMM and 30-day maternal readmissions.

RESULTS: The results for all regression models indicate that the MTF delivery volume had no significant impact on the probability of SMM. With regard to 30-day maternal readmissions, using the upper middle quartile as the comparison group due to the largest number of deliveries, MTFs in the lower middle quartile and in the highest quartile had a statistically significant higher likelihood of 30-day maternal readmissions.

CONCLUSION: This study shows no difference in SMM rates in the MHS based on obstetric case volume. This is consistent with previous studies showing differences in MHS patient outcomes compared to civilian healthcare systems. The MHS is unique in that it provides families with universal healthcare coverage and access and provides care for approximately 40,000 deliveries annually. There may be unique lessons on volume and outcomes in the MHS that can be shared with healthcare planners and decision makers to improve care in the civilian setting.

ABSTRACT

BACKGROUND: Body weight scales to height with a power of ≈2 (weight/height² ), forming the basis of body mass index (BMI). The corresponding scaling of body composition measured by abdominal computed tomography (CT) to height has not been established. The objective of this analysis was to quantify the scaling of body composition measured by a single-slice axial abdominal CT image (skeletal muscle, and visceral, subcutaneous, and total adipose tissue) to height in patients with colorectal cancer (CRC).

METHODS: This cross-sectional study included non-Hispanic white males and females, aged 18-80 years, who were diagnosed with stage I-III CRC at an integrated health care system in North America between January 2006 and December 2011. Body composition was measured by a single-slice axial CT image of the third lumbar vertebra and analysed with a semi-automated threshold segmentation procedure. Allometric regression models were used to quantify height scaling powers (β ± standard error) for each body composition measure, adjusted for age, for males and females. An interaction test was used to determine if height scaling powers were statistically significantly different between males and females.

RESULTS: Among 2036 subjects, the mean (standard deviation) age was 64 ± 11 years, 1008 (49.5%) were female, and the mean (standard deviation) BMI was 27.9 ± 5.4 kg/m² . Powers for skeletal muscle area were 1.06 ± 0.12 for males and 0.80 ± 0.12 for females (P = 0.049). Powers for visceral adipose tissue area were 1.81 ± 0.64 for males and 0.57 ± 0.79 for females (P = 0.16). Powers for subcutaneous adipose tissue area were 2.04 ± 0.42 for males and 0.81 ± 0.45 for females (P = 0.056). Powers for total abdominal adipose tissue area were 1.80 ± 0.46 for males and 0.76 ± 0.50 for females (P = 0.20).

CONCLUSIONS: Body composition measured by single-slice axial abdominal CT, particularly muscle area, scales to height with age-adjusted powers that are different than 2 and are distinct between males and females. These observations may have implications for the development of height-adjusted body composition indices in patients with cancer.

ABSTRACT

Commercially available wearable biosensors have the potential to enhance psychophysiology research and digital health technologies for autism by enabling stress or arousal monitoring in naturalistic settings. However, such monitors may not be comfortable for children with autism due to sensory sensitivities. To determine the feasibility of wearable technology in children with autism age 8-12 years, we first selected six consumer-grade wireless cardiovascular monitors and tested them during rest and movement conditions in 23 typically developing adults. Subsequently, the best performing monitors (based on data quality robustness statistics), Polar and Mio Fuse, were evaluated in 32 children with autism and 23 typically developing children during a 2-h session, including rest and mild stress-inducing tasks. Cardiovascular data were recorded simultaneously across monitors using custom software. We administered the Comfort Rating Scales to children. Although the Polar monitor was less comfortable for children with autism than typically developing children, absolute scores demonstrated that, on average, all children found each monitor comfortable. For most children, data from the Mio Fuse (96%-100%) and Polar (83%-96%) passed quality thresholds of data robustness. Moreover, in the stress relative to rest condition, heart rate increased for the Polar, F(1,53) = 135.70, p < 0.001, ηp² = 0.78, and Mio Fuse, F(1,53) = 71.98, p < 0.001, ηp² = 0.61, respectively, and heart rate variability decreased for the Polar, F(1,53) = 13.41, p = 0.001, ηp² = 0.26, and Mio Fuse, F(1,53) = 8.89, p = 0.005, ηp² = 0.16, respectively. This feasibility study suggests that select consumer-grade wearable cardiovascular monitors can be used with children with autism and may be a promising means for tracking physiological stress or arousal responses in community settings. LAY SUMMARY: Commercially available heart rate trackers have the potential to advance stress research with individuals with autism. Due to sensory sensitivities common in autism, their comfort wearing such trackers is vital to gathering robust and valid data. After assessing six trackers with typically developing adults, we tested the best trackers (based on data quality) in typically developing children and children with autism and found that two of them met criteria for comfort, robustness, and validity.

ABSTRACT

Cribra orbitalia is a phenomenon with interdisciplinary interest. However, the etiology of cribra orbitalia remains unclear. Recently, the appearance of cribra orbitalia was identified as vascular in nature. This study assessed the relationship between anatomical variation of vasculature, as determined by the presence of meningo-orbital foramina, and the presence of cribra orbitalia in 178 orbits. Cribra orbitalia was identified in 27.5% (49:178) of orbits (22.7%, 35:154 adult orbits and 58.3%, 14:24 subadult orbits) and meningo-orbital foramina were identified in 65.8% (100:152) of orbits. Among the 150 total intact adult orbits (i.e., orbital roof and posterior orbits both intact), cribra orbitalia was found in 35 (23.3%). Of these 35 occurrences of cribra orbitalia, 32 (91.4%) had the concurrent finding of a meningo-orbital foramen. However, in the absence of the meningo-orbital foramen, cribra orbitalia was only found in three sides out of the total sample of intact orbits (3:150; 2.0%). Fisher’s exact test revealed that the presence of cribra orbitalia and the meningo-orbital foramen were statistically dependent variables (p=0.0002). Visual evidence corroborated statistical findings- vascular impressions joined cribra orbitalia to meningo-orbital foramina. This study identifies that individuals who possess a meningo-orbital foramen are anatomically predisposed to developing cribra orbitalia. Conversely, cribra orbitalia is unlikely to occur in an individual who does not possess a meningo-orbital foramen. Thus, the antecedent of cribra orbitalia is both vascular and developmental in nature. This report represents an important advancement in the understanding of cribra orbitalia- there is an anatomical predisposition to the development of cribra orbitalia.

ABSTRACT

PURPOSE: To synthesize results from multiple studies to determine the effects of music interventions on chronic pain in older adults.

DESIGN: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline to identify and select studies.

METHODS: Relevant studies were identified from nine electronic databases. The Joanna Briggs Institute (JBI) critical appraisal checklists were employed to assess methodological quality. All authors performed screening, data extraction, and synthesis. Inclusion criteria were clinical trials investigating music for chronic pain in older adults aged 65 and older.

FINDINGS: Eight studies involving 524 older adults were included, comprising five randomized controlled trials and three quasi-experimental studies. Music interventions consisted of live music, recorded music, and active music, with a variety of music styles and genres. Despite the small and short-term effects, five studies presented significantly positive outcomes for reducing chronic pain and its common comorbidities in older adults following music interventions. Three studies reported decreased trends in pain scores although they did not reach statistical significance.

CONCLUSIONS: Music has potential to be an effective adjuvant for managing chronic pain in older adults.

CLINICAL RELEVANCE: Nurses can incorporate music into the care of older adults with chronic pain.

ABSTRACT

PURPOSE: This study examined the combined role psychological capital and social capital play in the severity of second victim syndrome experienced by registered nurses.

DESIGN: This research study was an ex post facto, cross-sectional, non-experimental survey design. Data were collected from October to December 2018. The study sample was composed of 1167 nurses recruited through 12 professional nursing associations in the United States.

METHODS: Self-report questionnaires were administered to measure psychological capital (Psychological Capital Questionnaire), social capital (Social Capital Outcomes for Nurses) and second victim syndrome (Second Victim Experience and Support Tool). Data cleaning and analysis of 1167 cases were conducted via SPSS v25 and structural equation modeling of 999 cases was conducted with AMOS v25.

FINDINGS: The SEM analysis demonstrated that psychological capital, on its own, had no effect on the severity of the second victim experience. Social capital, on its own, had a statistically significant relationship with second victim severity. The combined impact of social capital and psychological capital had a statistically significant effect on second victim severity.

CONCLUSIONS: The results of this study have practical implications that include unit-based peer support programs and an increased focus on supportive workplace cultures. Programmatic efforts should also focus on social capital at the team level as well as the importance of building self-efficacy through increasing mastery experiences, modeling of behavior, social persuasion and monitoring one’s physiological responses.

CLINICAL RELEVANCE: These findings demonstrate the importance of social capital to mitigation of second victim experiences, while also demonstrating that psychological capital has no effect on second victim severity. Building social capital and collective efficacy are critical to mitigation of second victim syndrome.
