ABSTRACT

IMPORTANCE: Individuals with persistent unilateral vestibular deficits experience loss of quality of life and increased risk of falling, and they have few well-supported options for effective treatment.

OBJECTIVES: To evaluate whether vestibular retraining using computerized dynamic posturography is associated with reduced participant-reported disability for patients with an objectively assessed unilateral peripheral vestibular deficit and to assess the feasibility of conducting a randomized clinical trial of vestibular retraining using computerized dynamic posturography.

DESIGN, SETTING, AND PARTICIPANTS: This single-group cohort study was conducted from April 29 to July 23, 2021, in a tertiary neurotology clinic among 13 individuals with a stable unilateral vestibular deficit present for more than 6 months, confirmed with videonystagmography and vestibular evoked myogenic potential testing. Statistical analysis was performed from July 7, 2021, to January 25, 2022.

INTERVENTIONS: Twelve twice-weekly sessions of posturography-assisted vestibular retraining with prescribed weight shifting tasks guided by an interactive display.

MAIN OUTCOMES AND MEASURES: Change in scores on the Dizziness Handicap Inventory (DHI), the Activities-Specific Balance Confidence (ABC) Scale, and the Falls Efficacy Scale-International (FES-I), which participants completed before and after retraining to measure their perception of their disability. They also completed posturography measurements. Secondary outcomes included tolerability of the intervention and rate of completion of the full protocol.

RESULTS: A total of 13 participants (8 men [62%]; median age, 51 years [range, 18-67 years]) were enrolled. All 13 participants completed the intervention and all follow-up. After treatment, the median changes in scores were -16 points (95% CI, -20 to 2) for the DHI, -9 (95% CI, -14 to 1) for the FES-I, and 11.9 (95% CI, 0-17.3) for the ABC Scale. Eight participants (62%) improved by greater than the minimum clinically important difference (MCID) for the DHI, whereas 4 (31%) exceeded the MCID for the ABC Scale, and 3 (23%) exceeded the MCID for the FES-I. Participants with moderate to severe disability at baseline (n = 7) had a larger magnitude of improvement in DHI scores than those with mild disability (n = 6) (-18 [95% CI, -78 to 2] vs -1 [95% CI, -8 to 16]). Six of the 7 patients (86%) with moderate to severe disability improved by greater than the MCID for DHI, wherease 4 of 7 patients (57%) improved by greater than the MCID for the ABC Scale, and 3 of 7 patients (43%) improved by greater than the MCID for the FES-I.

CONCLUSIONS AND RELEVANCE: This cohort study suggests that computerized, dynamic posturography-assisted retraining was associated with clinically meaningful improvements in participant-reported disability among those with stable unilateral vestibular deficit and moderate to severe disability. Further studies should compare posturography-assisted vestibular retraining with conventional physical therapy rehabilitation techniques.

ABSTRACT

YouTube is an increasingly accessible platform for families to obtain health information from; however, it is unregulated. The aim of this article was to assess the quality, reliability and accuracy of YouTube videos related to three common pediatric hip conditions: development dysplasia of the hip (DDH), slipped capital femoral epiphysis (SCFE) and Legg-Calve-Perthes disease. YouTube was searched using a variety of keyword combinations. Videos were analysed using Journal of the American Medical Association, Global Quality Score and condition-specific scores created specifically for this study. Video duration and the number of views were also recorded. In total 120 videos were analysed, 40 for each of DDH, SCFE and Perthes disease. YouTube videos from physicians and academic institutions/hospitals are of significantly higher quality, reliability and accuracy than videos from patients, nonphysicians and commercial outlets. The higher quality for physician videos is associated with significantly longer video. Differences between the three pediatric orthopaedic conditions were not statistically significant. Videos of higher quality may be used as an adjunctive tool to strengthen clinical consultation. Parents and caregivers should be guided to videos from academic institutions or hospitals as a way of improving health literacy.

ABSTRACT

Plantar fasciitis is the most common cause of heel pain. Pain can be persistent in some patients and interrupt daily activities and sportive activities. There are a lot of treatment options available for plantar fasciitis. We hypothesized that patients with chronic persistent plantar fasciitis can be successfully treated with radiofrequency nerve ablation (RFNA).Two hundred sixty-one patients with plantar fasciitis (378 feet) treated with RFNA from February 2017 to January 2019 were retrospectively assessed. All the patients had plantar heel pain for at least 6months. Based on their body mass index (BMI), the enrolled patients were divided into obese (BMI ≥ 30kg/m2) and non-obese (BMI < 30kg/m2) groups. The patients were asked to complete a questionnaire just before and after the procedure and during the final follow-up. The BNS Radiofrequency Lesion Generator was used during a single session. The patients’ information, including their visual analogue scale (VAS) score and American Orthopaedic Foot and Ankle Society (AOFAS) score, was assessed. During their final follow-up, the patients were asked to rate the success of their treatment by choosing one of the following options: completely successful, very successful, moderately successful, marginally successful, or not successful.The VAS and AOFAS scores of all the patients were evaluated pre-procedure, in the first month after procedure, and during the final follow-up (8-24 months). There was a statistically significant difference between the pre-procedure and postprocedure VAS scores (P < .001), there was no statistically significant difference between the VAS scores in the first month postprocedure and during the final follow-up.There was a statistically significant difference between the pre-procedure and postprocedure AOFAS scores (P < .001), there was no statistically significant difference between the AOFAS scores in the first month postprocedure and during the final follow-up.RFNA can be used as an alternative method to surgical procedures for treating plantar fasciitis because it is safe and effective. The advantages of RFNA are that patients can quickly return to their work and resume weight-bearing activities.

ABSTRACT

OBJECTIVE: To compare the retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) thickness and intraocular pressure in reproductive age and postmenopausal women.

METHODS: The study included 94 eyes of 47 reproductive age women (Group 1) and 94 eyes of 47 postmenopausal women (Group 2). In all women, RNFL and GCC thicknesses were measured by optical coherence tomography. Intraocular pressure levels were measured by Goldmann applanation tonometry. Generalized linear mixed models were conducted to test the differences between groups. Age- and body mass index (BMI)-adjusted partial correlation analysis was used to examine the associations between parameters.

RESULTS: There was a statistically significant difference in age and BMI between the two groups (P<0.001, P<0.001, respectively). There was no difference in all RNFL and GCC values between the reproductive age and postmenopausal women. The duration of postmenopause versus average, superior hemisphere, and superior values of RNFL and superior and inferior values of GCC were positively correlated with statistical significance in age- and BMI-adjusted partial correlation coefficient tests (r = 0.254, P = 0.017; r = 0.303, P = 0.004; r = 0.317, P = 0.003; r = 0.301, P = 0.004; r = 0.313, P = 0.003; r = 0.271, P = 0.011, with 95% confidence, respectively).

CONCLUSIONS: In this study, there was no significant difference in all RNFL and GCC values between the reproductive age and postmenopausal women after adjusting for age and BMI. However, we observed that a long postmenopausal period was associated with higher RNFL and GCC values.

ABSTRACT

BACKGROUND: Although primary microvascular angina (PMVA) can be diagnosed clinically, the etiology and pathophysiology of PMVA remain unclear. The effects of conventional clinical medications (aspirin, statins, and nitrates) are unsatisfactory, and PMVA can lead to serious cardiovascular events. The present study was designed to analyze the correlation between the load perfusion cardiovascular magnetic resonance imaging (CMR) results and the Streptococcus sanguinis(S sanguinis) count and the correlations between the S sanguinis count in oral cavity subgingival plaque and changes in the plasma levels of platelet alpha-granule membrane glycoprotein 140 (GMP-140), fibrinopeptide A (FPA), von Willebrand factor (vWF), and homocysteine (Hcy) in patients with PMVA after increased anti-infective treatment of the oral cavity. This study also discusses the pathogenesis of PMVA from this perspective. The differences in the S sanguinis count in oral cavity subgingival plaque and oral health status between healthy people and PMVA patients will be compared, and the correlation between the oral cavity health status and disease in PMVA patients will be analyzed.

METHODS: The present randomized controlled trial with a parallel control group will be conducted in 68 PMVA patients diagnosed by the in-patient cardiology department. The selected patients will be randomly divided into 2 groups, one receiving routine drug treatment and the other a combination of anti-infective treatments. The normal control group will comprise 30 healthy people with no infectious oral cavity disease matched by age and sex. We will conduct CMR, and the presence of S sanguinis in subgingival plaques will be used to determine the bacterial count in PMVA patients. Blood samples will also be collected to determine the levels of GMP-140, FPA, vWF, and Hcy. S sanguinis in the subgingival plaque of PMVA patients will be further analyzed after increasing the oral cavity anti-infective treatment; the resulting changes and their correlations with changes in GMP-140, FPA, vWF, and Hcy levels will be assessed. Additionally, the differences in the S sanguinis count and the oral cavity health status of oral cavity dental plaque between healthy people and PMVA patients will be determined, and the correlation between the oral cavity conditions and PMVA will be analyzed. The relationship between the perfusion CMR results and the oral cavity S sanguinis count of PMVA patients, and the potential pathogenesis, will be explored. We will use the SPSS19.0 statistical software package to analyze the data. The measurements will be expressed as means±standard deviation. Student t test will be used for intergroup comparisons, a relative number description will be used for the count data, and the chi-square test will be used for intergroup comparisons. Multivariate logistic regression will be performed to identify associations. A P value < .05 will be considered significant.

DISCUSSION: In this study, the correlation between the perfusion CMR results and the S sanguinis count in oral cavity subgingival plaque of PMVA patients will be analyzed. Changes in the levels of GMP-140, FPA, vWF, and Hcy of PMVA patients after receiving increased oral cavity anti-infective treatment will be explored, and the difference in the S sanguinis count in oral cavity subgingival plaque and the oral cavity health status between healthy people and PMVA patients will be compared.

ABSTRACT

Lockdowns due to COVID-19 increased known risk factors for nonaccidental trauma (NAT), including economic instability and parental stress. We sought to evaluate potential changes in the frequency and types of fractures associated with NAT during the COVID-19 pandemic. A retrospective cross-sectional study was conducted using de-identified data obtained from the IBM Watson Health Explorys Cohort Discovery database. Systematized Nomenclature of Medicine-Clinical Terms were used to query the database for victims of NAT in 2019 and 2020. Within this cohort of patients, we then identified those who were also diagnosed with a fracture within 21 days of the NAT event. Demographic data were compared between 2019 and 2020 where possible using chi-squared testing, and relative risks for various fracture diagnoses were calculated with 95% confidence intervals. There were 9500 records overall of pediatric NAT in 2019 compared to 9350 in 2020. Of those, in 2019 550 were associated with a diagnosis of fracture versus 570 in 2020. The relative risk of fracture due to NAT in 2020 when compared to 2019 was not significantly higher [relative risk, 1.05 (95% confidence interval, 0.94-1.17)]. The relative risk for each category of fracture diagnosis in 2020 was slightly higher, but not to a statistically significant degree. Despite increasing known risk factors, the frequency of NAT remained unchanged as the result of the COVID-19 pandemic. We also did not identify significant changes in the risk of fracture due to NAT, nor any changes in the associated types of fractures.

ABSTRACT

BACKGROUND: Latinos are among the most heavily impacted populations by the COVID-19 pandemic in the United States due to intersectional barriers to care. Crowdsourcing open contests can be an effective means of community engagement but have not been well studied in Latino populations nor in addressing the COVID-19 pandemic.

OBJECTIVE: 1) to implement and evaluate a crowdsourcing open contest to solicit a name for a COVID-19 social marketing campaign for Latinos in Maryland; and 2) to conduct a thematic analysis of submitted entries to guide campaign messaging.

METHODS: To assess the level of community engagement in this crowdsourcing open contest, we conducted descriptive statistics of entries and votes, and demographics of participants. Submitted text was analyzed through inductive thematic analysis.

RESULTS: We received 74 entries within a brief 2-week period. The top 10 entries were chosen by community judges and the winner was decided by popular vote. We received 383 votes within 1 week. The most common themes were collective efficacy, self-efficacy, and perceived benefits of COVID-19 testing. We used these themes to directly inform our social marketing intervention and found that ads based on these themes became the highest performing.

CONCLUSIONS: Crowdsourcing open contests are an effective means of community engagement and an agile tool for guiding interventions to address COVID-19, including in populations impacted by healthcare disparities such as Latino communities. Thematic analysis of contest entries can be a valuable strategy to inform the development of social marketing campaign materials.

ABSTRACT

BACKGROUND: Canadian nurses are at the forefront of patient care delivery. Although the use of digital health technologies for care delivery is gaining momentum in Canada, nurses are encouraged to integrate virtual care into their practice. In early 2020, more Canadian nurses delivered care virtually compared with 3 years ago.

OBJECTIVE: This study seeks to uncover the professional characteristics of Canadian nurses accessing virtual care in 2020, understand how these characteristics differ across types of technologies, investigate whether the nurses accessing virtual care possess the skills and knowledge needed to use these technologies, and determine the important drivers of the uptake of virtual care observed in 2020.

METHODS: We used data from the 2017 and 2020 National Survey of Canadian Nurses. This survey collected data on the use of digital health technologies in nursing practice. It concerned regulated nursing professionals working in different health care settings and from different domains of nursing practice. We combined the chi-square independence test and logistic regression analysis to uncover the most relevant drivers of virtual care uptake by nurses in 2020.

RESULTS: In early 2020, before the declaration of the COVID-19 pandemic, nurses who delivered care virtually were predominantly nurse practitioners (135/159, 84.9%) and more likely to work in a primary or community care setting (202/367, 55%) and in an urban setting (194/313, 61.9%). Factors such as nursing designation (P<.001), perceived quality of care at the health facility where the nurses practiced (P<.001), and the type of patient record-keeping system they had access to (P=.04) had a statistically significant effect on the probability of nurses to deliver care virtually in early 2020. Furthermore, nurses’ perception of the quality of care they delivered through virtual technologies was statistically associated with their perception of the skills (χ²₄=308.7; P<.001) and knowledge (χ²₄=283.4; P<.001) to use these technologies.

CONCLUSIONS: This study emphasizes the critical importance of nursing designation, geographic location, and type of patient record-keeping system in predicting virtual care integration in nursing practice. The findings related to geographic location can be used by decision-makers for better allocation of digital health resources among care settings in rural and urban areas. Similarly, the disparities observed across nursing designations have some implications for the digital training of nurses at all levels of practice. Finally, the association between electronic medical record use and uptake of virtual care could accelerate the implementation of more modernized record-keeping systems in care settings. Hence, this could advance interoperability and improve health care delivery.

ABSTRACT

OBJECTIVES: Insufficient nutrition can predisposes women to infection, pregnancy losses, preeclampsia and anaemia as well birth of underweight baby whose survival is threatened. Therefore, this study was aimed to assess pregnant mothers’ nutrition knowledge, attitude, practice and associated factors.

METHODS: A multicenter cross-sectional study was conducted among 378 participants who were selected using a systematic random sampling technique. Quantitative data were collected using a structured and interviewer-administered questionnaire, which consisted of questions on sociodemographic features, obstetrics characteristics and pregnant women’s nutrition knowledge, attitude and practice. Data entry and analysis were done using Statistical Package for the Social Sciences statistical version 23. Binary logistic regression analysis was done to identify associated factors. All variables with p-value of < 0.23 in bivariate analysis were included in multivariate analysis, and finally, statistical significance was declared at p-value < 0.05 with 95% confidence interval.

RESULT: From 378 women participated, a total of 231 (61.1%) respondents were in age range of 25-34 years. About 148 (39.1%) of women were not knowledgeable, 153 (40.5%) had an unfavourable attitude, and 47.7% had poor dietary practice. Knowledge (adjusted odds ratio = 4.5; 95% confidence interval: 2.88, 10.06, p = 0.03), attitude (adjusted odds ratio = 3.6; 95% confidence interval: 2.43, 6.66, p = 0.04) and practice (adjusted odds ratio = 3.6; 95% confidence interval: 2.43, 6.66, p = 0.036) were all significantly associated with maternal education. Regarding their occupation, merchant women were seven times (adjusted odds ratio = 7.02; 95% confidence interval: 2.88, 17.09, p = 0.01) more likely to have knowledge and government employees were six times (adjusted odds ratio = 6.05; 95% confidence interval: 3.58, 13.05, p = 0.04) more likely to be knowable than housewives. Moreover, multiparous women were 4.77 times (adjusted odds ratio = 4.77; 95% confidence interval: 1.15, 8.66, p = 0.002) more likely to be knowledgeable compared to primigravida women. Monthly income was also associated to attitude (adjusted odds ratio = 0.45, 95% confidence interval: 0.10, 1.66, p = 0.03). Women who had a favourable attitude were five times (adjusted odds ratio = 5.25; 95% confidence interval: 2.36, 9.62, p = 0.04) more likely to have good nutritional practices during pregnancy.

CONCLUSION: Pregnant women’s knowledge, attitude and practice towards nutrition in this area were low. The educational status of women was associated with knowledge; attitude and practice. Likewise, occupation and parity were associated with knowledge; and attitude was also found to be a determinant factor of nutritional practice. Therefore, community nutritional education and antenatal nutritional counselling need to be strengthened in the area.
