ABSTRACT

AIM: To compare the participation attendance and involvement of children and young people with and without cerebral palsy (CP) in a low-resource area of Uganda.

METHOD: Eighty-two children and young people with CP aged 6 to 22 years (49 males, 33 females) and 81 age- and sex-matched peers without CP (6 to 22 years; 48 males, 33 females) participated in this population-based, cross-sectional study. Data on attendance and involvement in 20 home and community activities were obtained using Picture My Participation, an instrument intended to measure participation in children with disabilities, particularly in low- and middle-income countries. Non-parametric statistical methods were used to assess between-group differences. Effect size estimates were calculated.

RESULTS: Pooled attendance across all activities was lower in children and young people with CP than in children and young people without CP (p < 0.001) and for each activity item (p = 0.004 to p < 0.001). The effect sizes for each activity were 0.2 to 0.7. Between-group differences were larger for community activities than for home activities. Pooled involvement across all activities was less in the group with CP (p < 0.001) and for each activity (p = 0.014 to p < 0.001). The effect sizes for each activity were 0.2 to 0.5. Children and young people in Gross Motor Function Classification System (GMFCS) levels I and II had higher attendance (p < 0.001) and involvement (p = 0.023) than those in GMFCS levels III to V.

INTERPRETATION: Participation of young people living with CP in Uganda was restricted, especially for community activities. There is a need to identify context-specific participation barriers and develop strategies to overcome them.

ABSTRACT

INTRODUCTION & OBJECTIVES: In systemic therapy trials, a decreasing neutrophil-to-lymphocyte ratio (NLR) after treatment for metastatic renal cell carcinoma (RCC) has been associated with improved oncologic outcomes. Paradoxically, for patients with localized RCC treated with upfront surgery the opposite effect has been reported. We thus aimed to evaluate NLR dynamics on localized RCC recurrence.

MATERIALS AND METHODS: Treatment naïve patients with localized RCC managed surgically between 2005 and 2020 were included. Preoperative NLR was calculated within 6-weeks prior to surgery and postoperative NLR was calculated between 4 and twelve-weeks after surgery. Patients were followed for disease recurrence, noting metastatic sites and postoperative infections. Cox regression were used to determine whether the relative change in postoperative NLR was associated with metastasis-free survival (MFS) and cancer-specific survival (CSS), adjusted for preoperative NLR.

RESULTS: In the cohort of 3310 patients, 996 (30%) had postoperative NLR available. These patients generally had more advanced disease, with 100 developing metastases and 38 dying from kidney cancer. Median MFS follow-up was 4.4 years. Decreasing 2-month postoperative NLR was associated with non-statistically significant worse MFS and CSS (HR 0.79, 95% 0.50, 1.24, P = .3; HR 0.83, 95% C.I. 0.40, 1.73; P = .6). On sensitivity analysis, across all NLR measurements, with NLR as a time-dependent covariate, results were similar, with a declining NLR associated with adverse MFS (HR 0.85, 95% CI 0.69, 1.30, P-value = .10), though not meeting conventional levels of significance.

CONCLUSION: In higher-risk localized RCC patients, postoperative NLR is not suitable as a biomarker for predicting recurrences.

ABSTRACT

BACKGROUND: Troponin positive chest-pain with unobstructed coronary arteries (TPCP-UCA), occurs in 6% of cases of patients presenting with acute coronary syndrome (ACS). Whilst TPCP-UCA patients are known to be younger with less cardiovascular risk factors when compared to obstructive coronary disease (MICAD), no validated methods exist to reliably delineate these two conditions prior to coronary angiography.

METHODS: We analysed 142 patients with MICAD and 127 patients with TPCP-UCA from 2015 to 2019. Several key predetermined clinical, biochemical and electrocardiograph (ECG) parameters, as well as Global Registry of Acute Coronary Events (GRACE) score, were collected for all patients. All TPCP-UCA patients underwent cardiac magnetic resonance imaging (cMRI).

RESULTS: Patients with TPCP-UCA were younger than MICAD (44 vs 68 yrs, p<0.01), and with less cardiac risk factors of hypertension (31% vs 68%, p<0.01), hypercholesterolaemia (23% vs 56%, p<0.01), diabetes (11% vs 45%, p<0.01), prior ischaemic heart disease (8% vs 42%, p<0.01) and smoking history (29% vs 50%, p<0.01). Peak troponin (MICAD 2,084.5 ng/L vs TPCP-UCA 847.0 ng/L, p=0.02), serial-to-initial troponin ratio (MICAD 13.5 vs TPCP-UCA 5.1, p<0.01), and peak-to-initial troponin ratio (MICAD 69.6 vs TPCP-UCA 14.0, p<0.01) were all higher in the MICAD group. GRACE scores were significantly different across the two cohorts (TPCP UCA 74 vs MICAD 106, p<0.01), with a receiver operator characteristic (ROC) curve statistic of 0.794 (95% CI 0.739-0.850). On ECG analysis, MICAD had greater prevalence and sum of ST depression (40% vs 19% p<0.01; 1.6 mm vs 0.44 mm, p<0.01) and T wave inversion (37% vs 17%, p<0.01), whilst TPCP-UCA had greater presence of PR depression (20% vs 3% p<0.01), and longer repolarisation (T wave peak to end 89 ms vs 83 ms, p=0.04; T wave peak to end/corrected QT 0.208 ms vs 0.193 ms, p=0.03). All TPCP-UCA patients underwent cMRI. Aetiology was found in 82% of cases, with the leading diagnosis being myocarditis (58%), followed by infarction (8%), whilst 18% had a normal cMRI.

CONCLUSIONS: TPCP-UCA is an important differential for patients presenting with ACS, and has several key demographic, biochemical and electrocardiographic differences. The present findings are hypothesis generating, thus prospective studies are required to determine and validate potential clinical utility.

ABSTRACT

BACKGROUND: Adherence to oral anticoagulants (OACs) in patients with atrial fibrillation (AF) is important in preventing stroke. The dominance of retrospective studies using administrative data has led to a lack of data on psychosocial determinants of adherence and prevented comparison of adherence between OAC drug classes. OAC switching is another aspect of adherence that is unexplored.

METHODS: A prospective design was utilized to measure AF patients’ self-reported adherence and OAC switching, and to identify their clinical, demographic, and psychosocial determinants. Participants were recruited from specialized AF clinics in Canada and followed for up to 2 years. Data were collected via telephone every 3-4 months using a structured survey. Adherence was measured using the Morisky Medication Adherence scale (©MMAS-8).

RESULTS: The included participants (N = 306) were followed for a median follow up time of 14.1 months and had an average of 3.2(SD 1.4) study visits. The mean self-reported adherence on the ©MMAS-8 was 7.28(SD 0.71) for patients receiving care at specialized AF clinics. Older age, experiencing a bleed, and higher satisfaction with the burden of medications were significantly associated with higher adherence. Drug class did not have any significant impact on adherence. 7.8% of the cohort experienced a switch with most of them being from warfarin to DOAC. Taking warfarin as the index medication, experiencing a bleed and older age were significantly associated with higher odds of switching.

CONCLUSION: Patients with AF reported high adherence to their OAC therapy however being on DOAC may not translate to better adherence compared to VKA. Improving satisfaction with the burden of therapy is important in improving adherence.

ABSTRACT

OBJECTIVES: Following an earlier National Health and Nutrition Examination Survey (NHANES) 2005-2008 analysis, we investigated the association between urine antimony and sleep health using more recent data, new measures of sleep health, and multiple measures of urine density adjustment in NHANES 2009-2016.

DESIGN: A cross-sectional study.

SETTING: United States, national population-based survey.

MEASUREMENTS: Multinomial logistic regression (sleep duration) and a generalized linear model with log-binomial regression (OSA, daytime sleepiness, sleep problems) were used to analyze the association of urinary antimony with sleep health outcomes. Urine creatinine and osmolality were considered, combined with statistical adjustment and standardization to account for urine density.

PARTICIPANTS: A total of 8133 adult participants over 20 years of age were used using NHANES 2009-2016.

RESULTS: We did not observe associations between urine antimony and short sleep duration or sleep problems. We observed mixed results for long sleep duration; there was a negative association in NHANES 2015-2016 and no association in NHANES 2009-2014. For self-reported symptoms of OSA, which were only available in 2015-2016, we observed a positive association for upper quartile urine antimony compared with the first quartile (RR = 1.24; 95% CI: 1.03, 1.50) and a test for trend, P= .02.

CONCLUSION: Urinary antimony was not consistently associated with short sleep duration, long sleep duration, or sleep problems, despite the findings from a relatively recent scientific article using earlier waves of NHANES. We observed a positive association between antimony and symptoms of OSA; this cross-sectional analysis requires confirmation.

ABSTRACT

OBJECTIVE: The purpose of this study was to assess whether beliefs about the origin of the popping sound and the effects of thrust manipulation (TM) were in agreement with current scientific evidence and whether a practitioner’s explanation could influence patient beliefs of theoretical mechanisms.

METHODS: A cross-sectional online survey was conducted in Italy from January 7, 2019 to April 20, 2019. The questionnaire was sent to 900 Italian adults through online recruitment, including people with and without a history of manipulation, such as given by physiotherapists, chiropractors, osteopaths, and manual medicine physicians to manage musculoskeletal disorders. The questionnaire consisted of 11 multiple-choice questions and could be completed within 15 weeks. The Likert scale was used to investigate participants’ attitudes. Sex and previous experience of TM variables were evaluated using a Student’s t-test; a 1-way F analysis of variance test was performed to evaluate age, educational qualification, and the professional who performed the TM.

RESULTS: We retrieved 478 questionnaires, including 175 participants with no TM history and 303 with TM history. There were 31% of participants (n = 94) with a history of TM who reported they did not receive explanations regarding manipulation. The participants’ beliefs mostly disagreed with the current hypotheses provided by the scientific literature on the theoretical mechanisms of popping sound (tribonucleation and cavitation). There were 9.9% (n = 30) of participants who answered “realignment of bone positional fault” to explain the mechanism behind TM. There was a high degree of agreement with the belief that the popping sound should be present for a successful TM (respectively, 2.8 standard deviation [SD; 1.2] and 2.6 SD [1.2] for TM+ and TM- participants). No statistically significant differences were found between participants with and without a history of TM.

CONCLUSION: The participants in this study reported a belief that popping was related to effectiveness of TM. A high percentage of this sample had beliefs about TM mechanisms for the audible popping sound that were inconsistent with current literature. Beliefs were similar between groups, suggesting that instructions given by TM practitioners did not seem to be an influence on these patients’ beliefs.

ABSTRACT

OBJECTIVE: The purpose of this study was to assess self-reported data from a sample of U.S. doctors of chiropractic during the COVID-19 pandemic about levels of psychological stress and beliefs of the association between chiropractic spinal manipulation and the immune system.

METHODS: Chiropractors in the United States were invited via social media and e-mail to complete a survey about chiropractic and COVID-19. The survey collected demographic information, office protocols, changes made during the COVID-19 pandemic, chiropractic profession opinions, information related to stress, and personal beliefs from April 19 to May 3 of 2020. Data were analyzed using descriptive statistics.

RESULTS: Of approximately 77000 U.S.-licensed chiropractors,750 responded. Of this sample, 51.2% reported moderate and 30.4% reported severe levels of psychological stress. The primary stressors were financial and business concerns. There was a mixed response regarding beliefs if there was evidence to support a connection between spinal manipulation and the immune system. A majority (76.1%) responded that there should be no advertising for immune-boosting effects of spinal manipulation during the pandemic. A minority (18.3%) reported adding use of telehealth to deliver their services.

CONCLUSION: A majority of chiropractors included in this survey reported that the COVID-19 pandemic caused them psychological stress. More than half of the respondents reported moderate stress, with the second highest number of respondents reporting severe stress. Subgroup differences were noted in stress levels and causes, as well as pandemic-related practice changes. A dichotomy was noted between beliefs and recommended actions about effects on the immune system, which may represent that providers are aware of current evidence and considering association recommendations.

ABSTRACT

OBJECTIVE: The purpose of this study was to compare the immediate effect of spinal manipulation (SMa) and spinal mobilization (SMo) on muscular responses, spinal stiffness, and segmental spinal pressure evoked pain in a population of participants with chronic middle back pain (MBP).

METHODS: In a crossover randomized trial, 2 experienced chiropractors assessed whether volunteers were eligible for the protocol according to a list of specific inclusion and exclusion criteria. Individuals with MBP participated in 2 experimental sessions within 72 hours. During the first session, participants randomly received a SMa or SMo delivered by an apparatus using a servolinear motor. During the second session, the other modality was delivered. Spinal stiffness and pressure-provoked pain intensity outcomes were assessed before and after each therapy, and muscular responses were recorded during the treatment using surface electromyographic sensors. Signed-rank Wilcoxon tests for muscular responses and generalized model for repeated measure for spinal stiffness and pressure-provoked pain were used for statistical analyses.

RESULTS: Among the 32 potential participants, 26 (mean age 29.9 [±9.14], 15 women) completed both sessions. Between-group differences were observed for the muscular response amplitude (P < .001), and indeed the normalized RMS muscular response was found to be higher during SMa than SMo. Similar results were observed for pressure-provoked pain intensity at the level of therapeutic modality application (P = .002) as a higher decrease in pain was found after SMa (47.9 [±22.8] to 36.6 [±23.7]) compared with SMo (47.2 [±23.2] to 45.5 [±24.3]). No between-group differences were found for spinal stiffness change, nor for terminal (P = .08) and global spinal stiffness (P = .06).

CONCLUSION: In a controlled environment, spinal manipulation and mobilization generated different muscle responses and had different immediate effects on pressure-provoked pain intensity for subjects with MBP.

ABSTRACT

OBJECTIVE: The purpose of this study was to estimate the significance of individual change using 5 statistical indicators in 2 samples of patients treated for low back pain.

METHODS: This secondary analysis used observational and clinical trial data from 2 samples of patients with low back pain to compare 5 ways of estimating significant individual change on the Impact Stratification Score (ISS) administered at the following 2 time points: 3 months apart in an observational study of 1680 patients undergoing chiropractic care, and 6 weeks apart in a randomized trial of 750 active-duty military personnel with low back pain. The following 5 methods were compared: (1) standard deviation index; (2) standard error of measurement (SEM); (3) standard error of estimate (SEE); (4) standard error of prediction (SEP); and (5) the reliable change index (RCI). The ISS is the sum of the Patient-Reported Outcomes Measurement Information System (PROMIS)-29 v2.1 physical function, pain interference, and pain intensity scores and is scored to have a possible range of 8 (least impact) to 50 (greatest impact).

RESULTS: The amount of change on the ISS needed for significant individual change in both samples was 5 for the SEM and for the SEE and 7 for the SEP and RCI.

CONCLUSIONS: The results of the current study provide some preliminary support for use of the SEP or the RCI to identify significant individual change and provide estimated thresholds of individual change that can be used for the ISS. The SEP and RCI estimates of significant change were consistent with retrospective ratings of change of at least moderately better in prior research. These 2 were less likely than other methods to classify people with low back pain as responders who have not actually gotten better (false positive). In contrast, the SEM and SEE were less likely to miss real change (false negative).

ABSTRACT

OBJECTIVE: The purpose of this study was to identify social and clinical factors associated with levels of functional disability (FD) in older adults with low back pain (LBP) in the city of Manaus, Amazonas, Brazil.

METHODS: A cross-sectional study of 557 adults with LBP aged ≥60 years was completed. Sociodemographic and clinical features, pain intensity (Numeric Rating Scale), FD (Roland Morris Disability Questionnaire), physical activity (International Physical Activity Questionnaire-short version), body mass index, educational level, health perception, emotional level, and self-reported diseases were evaluated. Statistical analysis was used to verify the association between quantitative variables and a group; Student t test or Mann-Whitney test, and analysis of variance (normality assumption) or Kruskal-Wallis test (non-parametric), P value of less than .05.

RESULTS: There were 81.3% female participants, 54.9% self-reported their race and/or skin color as brown, and 37.8% were sedentary. Pain intensity scores were 6.26 ± 2.19 in female participants and 5.82 ± 1.84 in male participants. Mean FD scores were 11.68 ± 6.08 for female participants and 9.61 ± 5.76 for males participants, although 39.7% of the total group presented with severe disability (score ≥14) and FD was associated with female sex (P = .001), physical activity (P≤ 0.001), body mass index (P≤ .001), emotional level (P < .001), and health perception (P < .001).

CONCLUSION: In this group of older adults with LBP, FD was associated with female sex, level of physical activity, body mass index, emotional level, and health perception. Many factors that were identified with FD are modifiable; therefore, interventions, such as nutrition education and re-conceptualization of self-emotional and health perception, may have potential to help in preventing and reducing FD.
