ABSTRACT

OBJECTIVES: The main objective was to improve the provision of clinical care in pressure injury prevention related to the use of medical devices focused on nasogastric probes.

INTRODUCTION: The insertion of nasogastric probes could lead to the formation of medical device-related pressure injuries (MDRPI). The risk increases with the length of the probe insertion and is higher in patients in intensive care. MDRPI prevention is mostly based on appropriate skin and mucosa membrane and tissue monitoring and positioning of the medical devices.

METHODS: The project has been conducted based on JBI Implementation approach for promoting change in healthcare practice. A baseline audit on MDRPI prevention was undertaken and involved 21 nurses and 12 patients using a questionnaire for nurses and a record sheet for patient’s monitoring. The intervention included education, clinical practice training, consultation, and other strategies. A follow-up audit was undertaken, including all original participants. Results data on changes in compliance were measured using descriptive statistics embedded in JBI-PACES in the form of percentage changes from baseline.

RESULTS: There were significantly improved outcomes across all best practice criteria. The level of knowledge of nurses increased. Skin barrier creams and mass-supplied fixation are now used to prevent skin injuries on the nose. The new monitoring and documentation is more accurate and in line with evidence-based practice.

CONCLUSION: Overall, the project achieved an improvement in evidence-based practice in the prevention of MDRPI in patients with nasogastric probes based on nurses’ increased level of knowledge and usage of appropriate preventative measures.

ABSTRACT

OBJECTIVES: The project aimed to assess compliance with evidence-based criteria regarding the use of clinical supervision amongst district nurses and to improve knowledge and engagement in clinical supervision activities within the workplace.

INTRODUCTION: It is important to provide clinical support to all healthcare workers that provide opportunities to develop and be listened to in a supervised environment. Clinical supervision is seen as a key element to provide this support. It provides a professional working relationship between two or more members of staff where the reflection of practice and personal emotion can be discussed, which is outlined in many policies and guidelines.

METHODS: A baseline audit was carried out using the JBI Practical Application of Clinical Evidence System program involving 16 participants in one district nursing team in South Wales. The first step involved the development of the project and generating the evidence. Following this, a baseline audit was conducted, and educational training on clinical supervision was undertaken followed by clinical supervision sessions. A postimplementation re-audit was conducted following implementation.

RESULTS: A total of 16 participants enrolled on the project. Receiving basic training and participating in clinical supervision was much higher than the baseline audit with both increasing to 100% compliance. Furthermore, 94% of participants were aware of clinical supervision activities and 88% knew of existing records on clinical supervision. The project results show a large increase in compliance with all of the criteria.

CONCLUSION: Overall the implementation project achieved an improvement in evidence-based practice regarding clinical supervision in primary care.

ABSTRACT

OBJECTIVES: Adverse childhood experiences (ACEs) including physical, emotional, or sexual abuse; neglect; and/or exposure to household instability have been associated with adult emergency department utilization, but the impact of parental ACEs on pediatric emergency department (PED) utilization has not been studied. The primary aim was to determine if parental ACEs impact resource utilization as measured by (1) frequency of PED utilization, (2) acuity of PED visits, and (3) 72-hour PED return rates. The secondary aim was to determine if resilience interacts with the impact of parental ACEs on PED utilization.

METHODS: This study is a cross-sectional survey using previously validated measures of ACEs, resiliency, and social determinants of health screening. Surveys were administered from October 17, 2019, to November 27, 2019, via iPad by research assistants in our institution’s PEDs. Survey responses were linked to data abstracted from the electronic health record. Descriptive statistics were used to characterize our study population. Pearson correlation was used to identify correlation between ACEs, social determinants of health, and PED utilization measures.

RESULTS: A total of 251 parents had complete data. Parental ACEs were positively associated with frequency of PED visits (incidence rate ratio, 1.013). In addition, high levels of parental resilience attenuated the association between parental ACEs and the number of severe acuity visits and were associated with fewer 72-hour return visits (incidence rate ratio, 0.49).

CONCLUSIONS: Parental ACEs appear to be positively associated with frequency of PED utilization and inversely associated with higher-acuity PED visits and parental resiliency.

ABSTRACT

OBJECTIVE: To evaluate and compare postoperative analgesic effects of grapiprant and carprofen in dogs undergoing ovariohysterectomy.

ANIMALS: 42 sexually intact female healthy dogs (< 35 kg and 0.5 to 7 years old) were enrolled.

PROCEDURES: In a masked, randomized, noninferiority clinical trial, dogs received either 2 mg/kg of grapiprant or 4.4 mg/kg of carprofen orally 2 hours prior to ovariohysterectomy. Postoperative pain was assessed using the Glasgow Composite Pain Scale-Short Form (GCPS-SF) at extubation and 2, 4, 6, 8, 18, and 24 hours postextubation and compared to baseline. After each pain scoring, mechanical nociceptive testing with von Frey monofilaments (vF) was performed to assess hyperalgesia. Hydromorphone (0.05 mg/kg, IM) was administered to any dog with a GCPS-SF of ≥ 5/24. The noninferiority limit (NI) for the GCPS-SF was Δ = 3. The NI for vF was Δ = -0.2. Following noninferiority, a mixed-effect ANOVA and post hoc comparisons were made with the Tukey correction method (P < .05).

RESULTS: 3 dogs required rescue analgesia and were excluded from statistical analysis. Of the remaining 39 dogs, the upper CI for GCPS-SF was below the NI of 3 and the lower CI for vF was greater than the NI of -0.2, indicating noninferiority of grapiprant as compared to carprofen. There was no difference between treatment (P = .89) nor treatment by time (P = .62) for GCPS-SF. There was no difference between groups at any time point or over time when vF were used.

CLINICAL RELEVANCE: Our study results support the use of grapiprant as an analgesic alternative to carprofen in dogs undergoing ovariohysterectomy.

ABSTRACT

BACKGROUND: Legg-Calvé-Perthes disease (LCPD) is a childhood hip disease characterized by osteonecrosis of the femoral head. Because severe deformity of the femoral head can cause secondary osteoarthritis in adulthood, progressive collapse should be prevented in children with a necrotic epiphysis. The prognosis of patients with LCPD generally worsens as the age at disease onset increases, and the appropriate treatment for late-onset LCPD remains unclear. Based on the limited effect of nonoperative treatment using a nonweightbearing brace, flexion varus osteotomy (FVO) was introduced in 2010 as an initial treatment for late-onset LCPD in place of brace treatment, which we used in our institution before that time.

QUESTIONS/PURPOSES: We asked, (1) Which treatment, FVO or a nonweightbearing brace, is associated with a lower likelihood of progressive femoral head collapse in children whose diagnosis of LCPD was made at the age of ≥ 8 years and who were followed for a minimum of 3 years after their intervention? (2) What proportion of patients in the brace group had surgery despite the treatment, and what percentage of children in the FVO group had a second operation to remove hardware and/or additional operations?

METHODS: The initial treatment was applied in 181 patients with LCPD between 1995 and 2018 in our institution. Patients whose disease onset was at ≥ 8 years old (late-onset LCPD) with complete clinical and radiologic data were considered potentially eligible. In 2010, treatment for these patients changed from brace treatment to FVO for all patients. A total of 35% (42 of 121) of patients who were treated with a nonweightbearing brace between 1995 and 2009 and 40% (24 of 60) of patients who were treated with FVO between 2010 and 2018 were eligible. Among patients treated with a brace, 21% (nine of 42 patients) were excluded because of hospital transfer (three patients), short-term follow-up (three), the period from onset to the first visit was ≥ 7 months (two), and inability to use the brace because of mental incapacity (one patient). In patients treated with FVO, 12% (three of 24 patients) were excluded (two patients with a period from onset to the first visit ≥ 7 months and one with a comorbidity and multiple-epiphyseal dysplasia). Among the remaining patients, 79% (33 of 42 patients) were classified into the brace group and 88% (21 of 24 patients) were classified into the FVO group for analyses. There were no overlapping patients at the timepoint when the treatment strategy for late-onset LCPD changed. In the FVO group, subtrochanteric osteotomy with 35° to 40° of flexion and 15° to 20° of varus was performed using a locking compression plate for pediatric use. Patient demographics, radiographic parameters, and the assessment of femoral head deformity using the Stulberg classification were compared between the two groups. There was a greater proportion of boys than girls in both groups (brace: 88% and FVO: 86%), and there were no differences in the distribution of genders between the groups (p = 0.82). The right side was more frequently treated in the brace group, but there was no difference in laterality between the groups (brace: 58% right and FVO: 62% left; p = 0.16). There was no difference between groups in the median age at disease onset (9.0 years [range 8.0 to 12.5 years] in the brace group and 9.6 years [range 8.0 to 12.4 years] in the FVO group; p = 0.26). There was no difference between the groups in the period of treatment from onset (1.7 ± 1.9 months in the brace group and 1.5 ± 1.5 months in the FVO group; p = 0.73) or the follow-up period (6.7 ± 2.1 years in the brace group and 6.2 ± 2.1 years in the FVO group; p = 0.41). The LCPD stage at the first visit was assessed using the modified Waldenström classification. The intraobserver and interobserver values of the modified Waldenström classification, evaluated using kappa statistics, were excellent (kappa value 0.89 [95% CI 0.75 to 0.97]; p < 0.01) and good (kappa value 0.65 [95% CI 0.43 to 0.87]; p < 0.01). The radiographic degree of collapse at the maximum fragmentation stage was assessed using the lateral pillar classification. The intraobserver and interobserver reliabilities of the lateral pillar classification were excellent (kappa value 0.84 [95% CI 0.73 to 0.94]; p < 0.01) and excellent (kappa value 0.83 [95% CI 0.71 to 0.94]; p < 0.01). The degree of femoral head deformity at the most recent follow-up examination was compared between the groups in terms of the Stulberg classification, in which Classes I and II were classified as good and Classes III through V were classified as poor. The intraobserver and interobserver reliabilities of the Stulberg classification were good (kappa value 0.74 [95% CI 0.55 to 0.92]; p < 0.01) and good (kappa value 0.69 [95% CI 0.50 to 0.89]; p < 0.01). The evaluators were involved in the patients’ clinical care as part of the treating team.

RESULTS: Good radiographic results (Stulberg Class I or II) were obtained more frequently in the FVO group (76% [16 of 21 patients]) than in the brace group (36% [12 of 33 patients]), with an odds ratio of 5.6 (95% CI 1.7 to 18.5; p < 0.01). In the brace group, a subsequent femoral varus osteotomy was performed in 18% (six of 33) of patients with progressive collapse and hinge abduction, and implant removal surgery was performed approximately 1 year after the first procedure. This traditional varus osteotomy was occasionally performed in patients who were considered for conversion from nonoperative treatment before 2009 because FVO had not yet been introduced. In the FVO group, all patients (n = 21) had a second procedure to remove the implant at a mean of 10.5 ± 1.2 months postoperatively. Additional procedures were performed in 24% (five of 21) of patients, including a second FVO for progressive collapse (one patient), guided growth for a limb length discrepancy (one patient), and flexion valgus osteotomy for coxa vara in patients with a limb length discrepancy (three patients).

CONCLUSION: Our historical control study found that FVO may increase the possibility of obtaining good radiographic results (Stulberg Class I or II) compared with brace treatment for patients with late-onset LCPD, although surgical interventions after the first and second implant removal procedures may be indicated. Surgeons can consider FVO if they encounter patients with late-onset LCPD, which is a challenging condition. A larger study with long-term follow-up is needed to confirm the efficacy of FVO.

LEVEL OF EVIDENCE: Level III, therapeutic study.

ABSTRACT

BACKGROUND: Placenta previa is a pregnancy condition associated with the development of complications related to placental insufficiency, including hypertension, preeclampsia and perinatal mortality. Dysfunction in uteroplacental arteries causes the release of cytokines, leukotrienes and immunomodulatory hormones, which leads to an inflammatory reaction.

OBJECTIVES: The nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway and vascular endothelial growth factor (VEGF) are known to play crucial roles in inflammation and angiogenetic regulation. This study aimed to demonstrate the morphometric and immunohistochemical effects on inflammation and angiogenesis underlying placenta previa.

MATERIAL AND METHODS: Twenty pregnant patients with placenta previa and 20 healthy pregnant patients, all between 30 and 38 weeks gestational age, were included in the study. The gestational age of the pregnancies was determined according to the last date of menstruation and/or ultrasonographic measurements. Blood samples and clinical data were obtained from the prenatal patient groups. Samples were taken from the connecting stem region from both groups.

RESULTS: The mean difference between the control and placenta previa patients was statistically significant for the parameters of blood vessels in villi, diameter of floating small villus, decidual cells, syncytial knots, congestion in blood vessels, fibrinoid accumulation, and inflammation. Significant degeneration and apoptotic changes in the syncytial cells of the root villi and an increase in syncytial nodes and bridges were observed in the placenta previa specimens. In the connecting stem region of the placenta previa samples, blood vessel dilatation, endothelial cell hyperplasia and a higher number of syncytial nodes were observed. In the immunohistochemical examination of the placenta previa samples, an increase in NF-κB and VEGF expression was observed in the endothelial cells, syncytial cells and Hofbauer cells.

CONCLUSIONS: Vascular endothelial growth factor was found to stimulate endothelial cell proliferation and migration, and to significantly affect angiogenesis during the developmental process of the placenta and remodeling of the uterine vessels, inducing NF-κB signaling and apoptotic development during cytotrophoblastic invasion in the vascularization of the placenta.

ABSTRACT

BACKGROUND: Smartphones are increasingly used in health research. They provide a continuous connection between participants and researchers to monitor long-term health trajectories of large populations at a fraction of the cost of traditional research studies. However, despite the potential of using smartphones in remote research, there is an urgent need to develop effective strategies to reach, recruit, and retain the target populations in a representative and equitable manner.

OBJECTIVE: We aimed to investigate the impact of combining different recruitment and incentive distribution approaches used in remote research on cohort characteristics and long-term retention. The real-world factors significantly impacting active and passive data collection were also evaluated.

METHODS: We conducted a secondary data analysis of participant recruitment and retention using data from a large remote observation study aimed at understanding real-world factors linked to cold, influenza, and the impact of traumatic brain injury on daily functioning. We conducted recruitment in 2 phases between March 15, 2020, and January 4, 2022. Over 10,000 smartphone owners in the United States were recruited to provide 12 weeks of daily surveys and smartphone-based passive-sensing data. Using multivariate statistics, we investigated the potential impact of different recruitment and incentive distribution approaches on cohort characteristics. Survival analysis was used to assess the effects of sociodemographic characteristics on participant retention across the 2 recruitment phases. Associations between passive data-sharing patterns and demographic characteristics of the cohort were evaluated using logistic regression.

RESULTS: We analyzed over 330,000 days of engagement data collected from 10,000 participants. Our key findings are as follows: first, the overall characteristics of participants recruited using digital advertisements on social media and news media differed significantly from those of participants recruited using crowdsourcing platforms (Prolific and Amazon Mechanical Turk; P<.001). Second, participant retention in the study varied significantly across study phases, recruitment sources, and socioeconomic and demographic factors (P<.001). Third, notable differences in passive data collection were associated with device type (Android vs iOS) and participants’ sociodemographic characteristics. Black or African American participants were significantly less likely to share passive sensor data streams than non-Hispanic White participants (odds ratio 0.44-0.49, 95% CI 0.35-0.61; P<.001). Fourth, participants were more likely to adhere to baseline surveys if the surveys were administered immediately after enrollment. Fifth, technical glitches could significantly impact real-world data collection in remote settings, which can severely impact generation of reliable evidence.

CONCLUSIONS: Our findings highlight several factors, such as recruitment platforms, incentive distribution frequency, the timing of baseline surveys, device heterogeneity, and technical glitches in data collection infrastructure, that could impact remote long-term data collection. Combined together, these empirical findings could help inform best practices for monitoring anomalies during real-world data collection and for recruiting and retaining target populations in a representative and equitable manner.

ABSTRACT

BACKGROUND: Loneliness and social isolation are global public health challenges. Sensory impairments (SIs) are highly prevalent among older adults but are often ignored as a part of normal aging. Identifying the role of SIs in loneliness and social isolation could provide insight into strategies for improving public health among older adults.

OBJECTIVE: This study aims to analyze the effects of SIs on loneliness and social isolation among older adults in rural and urban China.

METHODS: This cohort study of 3069 older adults (aged 60+) used data from 4 waves (2011, 2013, 2015, and 2018) of the China Health and Retirement Longitudinal Study (CHARLS), a nationally representative survey of adults aged 45 years or older. SIs include hearing impairment (HI), vision impairment (VI), and dual sensory impairment (DSI). DSI is defined as the co-occurrence of VI and HI. Participants with complete data on hearing, vision, social isolation, and loneliness were included in the analysis. Generalized estimating equation models adjusted for covariates were used to examine the relationships of DSI with loneliness and social isolation among older adults.

RESULTS: Older adults in rural areas have higher prevalence of DSI, loneliness, and social isolation than their urban counterparts. In rural areas, participants with VI only (odds ratio [OR] 1.34, 95% CI 1.12-1.62; P=.002), HI only (OR 1.32, 95% CI 1.02-1.71; P=.03), and DSI (OR 1.84, 95% CI 1.56-2.18; P<.001) were more likely to experience loneliness compared with participants without SIs. DSI showed a statistically significant association with loneliness compared with VI only (OR 1.37, 95% CI 1.22-1.54; P<.001) and HI only (OR 1.39, 95% CI 1.13-1.72; P=.002). In urban areas, participants with VI only (OR 2.44, 95% CI 1.57-3.80; P<.001), HI only (OR 2.47, 95% CI 1.41-4.32; P=.002), and DSI (OR 1.88, 95% CI 1.24-2.85; P=.003) were more likely to experience loneliness compared with participants without SIs. DSI was not associated with the increased likelihood of loneliness compared with HI only or VI only. SIs were not associated with social isolation among older adults in urban and rural areas. Until 2018, 86.97% (2669/3069) reported VI, but only 27.11% (832/3069) and 9.45% (290/3069) were treated with glasses and cataract surgery, respectively; besides, 75 individuals received both glasses and cataract surgery treatment. The prevalence of HI was 74.39% (2283/3069) in 2018, but only 0.72% (22/3069) were treated with a hearing aid.

CONCLUSIONS: SIs are associated with an increased risk of loneliness rather than social isolation. A compounded risk of DSI on loneliness exists in rural areas rather than in urban areas. These findings expand our knowledge about the effects of SIs on loneliness and social isolation in non-Western populations. Interventions targeting HI only and DSI might be particularly effective for mitigating loneliness of older adults in urban and rural areas, respectively. Considering the high prevalence and low treatment rate of SIs, measures should be taken to make treatment more accessible.

ABSTRACT

INTRODUCTION: Patellofemoral pain (PFP) is a common overuse injury associated with physical activity including walking. The risk for PFP may increase if walking biomechanics change during a bout of walking. Since walking for exercise is often recommended to previously sedentary adults, this would be a cause for concern. The purpose of this study was to determine any differences in walking biomechanics associated with PFP between sedentary and active young women initially and following 30 minutes of walking for exercise.

METHODS: Fifteen sedentary and 15 active young women walked overground for 5 trials of three-dimensional gait analysis before and after a 30-minute treadmill walk. Peak knee flexion angle and extensor moment were compared between groups and before and after the 30-minute walk.

RESULTS: Comparing groups at baseline, peak knee flexion angle and peak knee extensor moment were not statistically significantly different between groups. Following the 30-minute walk, peak knee flexion angle and extensor moment increased slightly in both groups.

CONCLUSIONS: Smaller, not larger, peak knee flexion angle and extensor moment during walking have been associated with increased risk of PFP. Therefore, sedentary and active young women can walk for 30 minutes without further detrimental changes to walking biomechanics that may increase their risk of PFP.

ABSTRACT

The accuracy and ease of metabolite assignments from a complex mixture are expected to be facilitated by employing a multispectral approach. The two-dimensional (2D) ¹H-¹³C heteronuclear single quantum coherence (HSQC) and 2D ¹H-¹H-total correlation spectroscopy (TOCSY) are the experiments commonly used for metabolite assignments. The 2D ¹H-¹³C HSQC-TOCSY and 2D ¹H-¹³C heteronuclear multiple-bond correlation (HMBC) are routinely used by natural products chemists but have seen minimal usage in metabolomics despite the unique information, the nearly complete ¹H-¹H and ¹H-¹³C and spin systems provided by these experiments that may improve the accuracy and reliability of metabolite assignments. The use of a ¹³C-labeled feedstock such as glucose is a routine practice in metabolomics to improve sensitivity and to emphasize the detection of specific metabolites but causes severe artifacts and an increase in spectral complexity in the HMBC experiment. To address this issue, the standard HMBC pulse sequence was modified to include carbon decoupling. Nonuniform sampling was also employed for rapid data collection. A dataset of reference 2D ¹H-¹³C HMBC spectra was collected for 94 common metabolites. ¹³C-¹³C spin connectivity was then obtained by generating a covariance pseudo-spectrum from the carbon-decoupled HMBC and the ¹H-¹³C HSQC-TOCSY spectra. The resulting ¹³C-¹³C pseudo-spectrum provides a connectivity map of the entire carbon backbone that uniquely describes each metabolite and would enable automated metabolite identification.
