Comparison of longitudinal trends in self-reported symptoms and COVID-19 case activity in Ontario, Canada.

BACKGROUND: Limitations in laboratory diagnostic capacity impact population surveillance of COVID-19. It is currently unknown whether participatory surveillance tools for COVID-19 correspond to government-reported case trends longitudinally and if it can be used as an adjunct to laboratory testing. The primary objective of this study was to determine whether self-reported COVID-19-like illness reflected laboratory-confirmed COVID-19 case trends in Ontario Canada. METHODS: We retrospectively analyzed longitudinal self-reported symptoms data collected using an online tool-Outbreaks Near Me (ONM)-from April 20th, 2020, to March 7th, 2021 in Ontario, Canada. We measured the correlation between COVID-like illness among respondents and the weekly number of PCR-confirmed COVID-19 cases and provincial test positivity. We explored contemporaneous changes in other respiratory viruses, as well as the demographic characteristics of respondents to provide context for our findings. RESULTS: Between 3,849-11,185 individuals responded to the symptom survey each week. No correlations were seen been self-reported CLI and either cases or test positivity. Strong positive correlations were seen between CLI and both cases and test positivity before a previously documented rise in rhinovirus/enterovirus in fall 2020. Compared to participatory surveillance respondents, a higher proportion of COVID-19 cases in Ontario consistently came from low-income, racialized and immigrant areas of the province- these groups were less well represented among survey respondents. INTERPRETATION: Although digital surveillance systems are low-cost tools that have been useful to signal the onset of viral outbreaks, in this longitudinal comparison of self-reported COVID-like illness to Ontario COVID-19 case data we did not find this to be the case. Seasonal respiratory virus transmission and population coverage may explain this discrepancy.

Operative versus Nonoperative Management of Idiopathic Spinal Cord Herniation: Effect on Symptomatology and Disease Progression.

BACKGROUND: Idiopathic spinal cord herniation (ISCH) is a rare pathology characterized by extravasation of the spinal cord through a dural defect. The optimal algorithm for choosing operative or nonoperative management is not well elucidated, partially because of the rarity of this pathology. We present the largest single-center series of ISCH and compare operative treatment to conservative management. METHODS: A retrospective case series of all patients evaluated for treatment of ISCH at our institution between 2010 and 2019 was conducted. Demographic variables, presenting symptoms, and imaging characteristics were assessed for all patients. For patients who underwent operative treatment, surgical approach, postoperative course, and discharge outcomes were recorded. Follow-up notes were reviewed for status of symptoms and functional capabilities, which were synthesized into Odom's criteria score. RESULTS: Sixteen patients met the inclusion criteria for this study, 8 of whom underwent operative treatment. No significant differences were found between operative and nonoperative groups with regard to demographic variables or pathology characteristics. Odom's criteria scores for the operative cohort were 12.5% (1 of 8) Excellent, 62.5% (5 of 8) Good, 12.5% (1 of 8) Fair, and 12.5% (1 of 8) Poor. Odom's criteria scores for the nonoperative cohort were 16.7% (1 of 6) Excellent, 33.3% (2 of 6) Good, 16.7% (1 of 6) Fair, and 33.3% (2 of 6) Poor. There was no significant difference between Odom's criteria score distribution between the operative and nonoperative groups at latest follow up (P = 0.715). CONCLUSIONS: Conservative management of spinal cord herniation is an option that does not preclude symptomatic improvement in patients with idiopathic spinal cord herniation.

Trends in Restricting Symptoms at the End of Life from 1998 to 2019: A Cohort Study of Older Persons.

OBJECTIVES: To describe changes in the occurrence of restricting symptoms at the end of life from 1998 to 2019 and compare these changes according to the condition leading to death. DESIGN: Prospective longitudinal study. SETTING: Greater New Haven, CT. PARTICIPANTS: A total of 665 decedents from a cohort of 754 community-living persons, 70 years or older. MEASUREMENTS: The occurrence of 16 restricting symptoms was ascertained during monthly interviews. Information on the conditions leading to death was obtained from death certificates and comprehensive assessments that were completed every 18-months. For each restricting symptom, adjusted rates (per 100 person-months) were calculated separately for six multiyear time intervals. RESULTS: From 1998 to 2019, rates decreased for five (31.3%) restricting symptoms (difficulty sleeping; chest pain or tightness; shortness of breath; cold or flu symptoms; and nausea, vomiting, or diarrhea), increased for three (18.8%: arm or leg weakness; urinary incontinence; and memory or thinking problem), and changed little for the other eight (50.0%: poor eyesight; anxiety; depression; musculoskeletal pain; fatigue; dizziness or unsteadiness; frequent or painful urination; and swelling in feet or ankles). The decrease in rates was most pronounced for shortness of breath, with a reduction from 15.0 (95% credible interval = 11.7-18.6) in 1998 to 2001 to 8.2 (95% credible interval = 5.9-10.5) in 2014 to 2019, yielding a rate ratio (95% credible interval) of 0.92 (0.86-0.98). When evaluated according to the condition leading to death, the results were similar, with 10 of the 13 statistically significant rate ratios representing decreases in rates over time and only 3 representing increases. CONCLUSION: The occurrence of most restricting symptoms at the end of life has been decreasing or stable over the past two decades. These results suggest that end-of-life care has been improving, although additional efforts will be needed to further reduce symptom burden at the end of life.

Sonographic characteristics of pilomatricomas and their association with symptom duration.

This study aimed to investigate the associations between the sonographic findings and duration of symptoms in children with pilomatricoma.This study included 86 children with 95 lesions confirmed to be pilomatricoma after pathological examination. The associations between symptom duration and sonographic observations, including the presence or absence of peritumoral hyperechogenicity, calcification, and vascularity were investigated. The internal echogenicity of each pilomatricoma was scored using a 5-point scale based on echogenic spots and calcification with posterior acoustic shadowing. The Mann-Whitney U and Kruskal-Wallis tests were used for statistical analysis.We found that the absence of peritumoral hyperechogenicity and severity of calcification were associated with increased symptom duration. Calcification, (present, 19.19 ±â€Š18.99 months vs absent, 4.31 ±â€Š3.24 months; P < .01) and peritumoral hyperechogenicity (present, 5.02 ±â€Š5.80 months vs absent, 16.17 ±â€Š18.24 months; P < .01), and grade of internal echogenicity (grade 0/1/2/3/4 = 3 months [1 patient]/4.33 ±â€Š3.26 months [range, 1-12]/4.57 ±â€Š3.46 months [range, 2-12]/10.89 ±â€Š9.17 months [range, 3-28]/35.27 ±â€Š19.16 months [range, 9-60], respectively; P = .01 and <.01) were associated with significant differences in symptom duration. There were no significant between-group differences in vascularity (6.01 ±â€Š7.24 months; range, 1-48 vs 15.50 ±â€Š19.12 months; range, 1-60; P = .08).Pilomatricomas with a relatively short symptom duration were more likely to exhibit peritumoral hyperechogenicity and calcification with less severe posterior acoustic shadowing compared to lesions with a longer symptom duration. These sonographic findings provided useful information that facilitated the correct and rapid diagnosis of pilomatricoma.

Febrile Illness Evaluation in a Broad Range of Endemicities (FIEBRE): protocol for a multisite prospective observational study of the causes of fever in Africa and Asia.

INTRODUCTION: Fever commonly leads to healthcare seeking and hospital admission in sub-Saharan Africa and Asia. There is only limited guidance for clinicians managing non-malarial fevers, which often results in inappropriate treatment for patients. Furthermore, there is little evidence for estimates of disease burden, or to guide empirical therapy, control measures, resource allocation, prioritisation of clinical diagnostics or antimicrobial stewardship. The Febrile Illness Evaluation in a Broad Range of Endemicities (FIEBRE) study seeks to address these information gaps. METHODS AND ANALYSIS: FIEBRE investigates febrile illness in paediatric and adult outpatients and inpatients using standardised clinical, laboratory and social science protocols over a minimum 12-month period at five sites in sub-Saharan Africa and Southeastern and Southern Asia. Patients presenting with fever are enrolled and provide clinical data, pharyngeal swabs and a venous blood sample; selected participants also provide a urine sample. Laboratory assessments target infections that are treatable and/or preventable. Selected point-of-care tests, as well as blood and urine cultures and antimicrobial susceptibility testing, are performed on site. On day 28, patients provide a second venous blood sample for serology and information on clinical outcome. Further diagnostic assays are performed at international reference laboratories. Blood and pharyngeal samples from matched community controls enable calculation of AFs, and surveys of treatment seeking allow estimation of the incidence of common infections. Additional assays detect markers that may differentiate bacterial from non-bacterial causes of illness and/or prognosticate illness severity. Social science research on antimicrobial use will inform future recommendations for fever case management. Residual samples from participants are stored for future use. ETHICS AND DISSEMINATION: Ethics approval was obtained from all relevant institutional and national committees; written informed consent is obtained from all participants or parents/guardians. Final results will be shared with participating communities, and in open-access journals and other scientific fora. Study documents are available online (https://doi.org/10.17037/PUBS.04652739).

Advances in the Functional Assessment of Patients with Sarcoma.

Functional assessment of patients with osteosarcoma may yield unique insights into the guide and advance treatment. A range of patient-reported outcomes has been validated, including general health and condition-specific measures as well as computer adaptive testing. Health state utility measures, which facilitate comparative-effectiveness research, are also available. Beyond these surveys, and laboratory-dependent gait analyses, is the potential for real-world evaluation through research-oriented and consumer-oriented accelerometers. Initial studies have shown promising validity of these activity trackers and may also have implications for traditional oncologic outcomes.

Dyspnoea Assessment In Adults With End-Stage Kidney Disease: A Systematic Review.

BACKGROUND: Dyspnoea is a common, disabling symptom of people living with end-stage kidney disease (ESKD), which may persist despite optimal management. Dyspnoea assessments can be grouped according to the instruments that assess domains related to: sensory-perception (intensity, sensory quality), affective distress (unpleasantness) and impact/burden (function, quality of life). OBJECTIVES: To describe dyspnoea assessment in adults with ESKD receiving renal replacement therapy (RRT). DESIGN: Systematic review. METHODS: Five databases were searched. Primary studies reporting an assessment of dyspnoea in adults with ESKD receiving RRT were included. Studies were excluded where participants with ESKD had received palliative/conservative treatment (no dialysis) or renal transplant. Conference abstracts, protocols, commentaries and/or images were excluded. Two independent reviewers screened and extracted the data. Descriptive analysis summarised the (1) number and type of instruments used to assess dyspnoea; (2) which dyspnoea domains to be assessed and (3) rationale and context for dyspnoea assessment. RESULTS: From 2,234 records screened, 28 studies were eligible for inclusion (observational n = 22 and experimental n = 6). Across studies, 12 different instruments were identified (dyspnoea-specific n = 3, subscale of a comprehensive instrument n = 9). Most instruments (n = 11, 92%) assessed a single domain (intensity n = 6, unpleasantness n = 6 and impact/burden n = 5). Studies reported a rationale for measuring dyspnoea (n = 26) as either a characteristic of the participant cohort (n = 14) or as an outcome (n = 14). CONCLUSIONS: Surprisingly, a few primary studies reported assessment of dyspnoea in people with ESKD receiving RRT. When assessed, there was a predominance of unidimensional instruments. As dyspnoea is associated with adverse clinical outcomes, routine dyspnoea assessment may improve management and relieve suffering.

Objective to describe the most frequent signs and symptoms of infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods this is a narrative literature review carried out in April 2020; the search was performed on electronic databases and complemented with a manual review of the references of the selected papers and Brazilian Ministry of Health publications. Results the spectrum of clinical disease was wide; fever, coughing and dyspnea were the most frequent signs/symptoms, however, they may not be present, thus hindering case definition; gastrointestinal symptoms and loss of taste or smell have been reported among mild cases; dyspnea was frequent among severe and fatal cases. Conclusion considering the scarcity of diagnostic tests and the diversity of symptoms, health services should use a sensitive case definition, in order to adopt appropriate surveillance, prevention and treatment actions.

Symptom-Triggered Therapy for Alcohol Withdrawal Syndrome: a Systematic Review and Meta-analysis of Randomized Controlled Trials.

BACKGROUND: Benzodiazepines are the standard medication class for treating alcohol withdrawal. Guidelines recommend dosing based on objectively measured symptoms (symptom-triggered therapy) rather than fixed dose regimens. However, the superiority of symptom-triggered therapy has been questioned, and concerns have been raised about its inappropriate use and safety. We aimed to assess whether symptom-triggered therapy is superior to fixed dose schedules in terms of mortality, delirium, seizures, total benzodiazepine dose, and duration of therapy. METHODS: A systematic literature search using Medline, Embase, and the Cochrane Registry through February 2018 was conducted for randomized controlled trials of patients with alcohol withdrawal syndrome comparing fixed dose benzodiazepine schedules to symptom-triggered therapy. Risk of bias was assessed using the Cochrane Risk of Bias Tool. Outcomes were pooled using random effects meta-analysis. Heterogeneity was estimated using the I2 statistic. Strength of evidence was assessed using methods outlined by the Agency for Healthcare Research and Quality. RESULTS: Six studies involving 664 patients were included. There were no deaths and only one seizure in each group. Four studies reported delirium, which occurred in 4 out of 164 patients randomized to symptom-triggered therapy compared to 6 out of 164 randomized to fixed dose therapy (odds ratio, 0.64 [95% CI, 0.17-2.47]). Three studies reported duration of therapy, which was 60.4 h less with symptom-triggered therapy (95% CI, 39.7-81.1 h; p < 0.001). Six studies reported total benzodiazepine dosage, which was 10.5 mg in lorazepam-equivalent dosing less with symptom-triggered therapy (95% CI, 7.1-13.9 mg; p = 0.011). DISCUSSION: Moderate strength evidence suggests that symptom-triggered therapy improved duration of therapy and total benzodiazepine dose in specialized detoxification settings of low-risk patients but the applicability of this evidence in general hospital settings is low. There was insufficient evidence for any conclusions about symptom-triggered therapy for the major outcomes of mortality, seizure, and delirium in any setting. PROSPERO REGISTRATION: CRD42017073426.

Assessment of pediatric bowel and bladder dysfunction: a critical appraisal of the literature.

OBJECTIVE: Bowel and bladder dysfunction (BBD) is a clinical syndrome defined by the coexistence of constipation and lower urinary tract symptoms. Although BBD is a common condition in pediatric urology and can cause significant stress to patients/parents, clinical diagnosis of BBD has not been standardized. Bowel and bladder dysfunction instruments have gained popularity over the past decade to aid in diagnosis. In this review, the currently published BBD symptom questionnaires were summarized and an analysis on their psychometric validation process was provided. SUBJECTS/PATIENTS: PubMed was searched for articles on BBD symptom questionnaires/instruments/surveys since 2000. Two investigators (R.Y.J. & M.S.K.) conducted the search in duplicate. The search was limited to English language. The included search terms were 'dysfunctional elimination syndrome', 'bowel and bladder dysfunction', 'dysfunctional voiding', 'voiding dysfunction symptom score', and 'dysfunctional voiding symptom scale'. Reference lists of included studies were screened for missed studies. Unpublished abstracts presented at the following scientific meetings were also manually searched for: the American Urological Association, the Society for Pediatric Urology, and the American Academy of Pediatrics Section on Urology. Exclusion criteria included articles in languages other than English, articles not related to BBD questionnaires, and articles not pertaining to pediatric patients. RESULTS: After initial search, a total of 54 articles were obtained. Of the seven questionnaires reviewed, only one did not measure sensitivity or specificity. Almost all questionnaires showed excellent discriminative property with an Area under the curve (AUC) >0.85. Criterion validity was not reported in any of the questionnaires. Known-group validation was used as a common method to evaluate construct validity. Internal consistency was reported in 2 studies, and only 1 study measured questionnaire responsiveness during initial validation. CONCLUSIONS: Although BBD is a common pediatric urology condition; a large amount of heterogeneity exists in the questionnaires' psychometric testing and validation process. To further improve the diagnosis and management of BBD in pediatric patients, there is a need for consensus on the gold standard questionnaire measure.

Cluster analysis of autism spectrum disorder symptomatology: Qualitatively distinct subtypes or quantitative degrees of severity of a single disorder?

The decision to collapse several related disorders into a single diagnosis of Autism Spectrum Disorder (ASD) generated significant controversy and debate. There has been mixed evidence as to whether various ASD subtypes are qualitatively distinct or if they exist on a spectrum of symptom severity. The present study conducted a two-step cluster analysis of major ASD symptoms in a sample of 147 young males with ASD aged between 6yr and 18yr with IQ > 70. Results indicated that a two-cluster solution (high and low severity of ASD symptomatology) was reliable and valid. Further, the construct of challenging behaviour was not a necessary component of the two-cluster solution, verifying the new conceptualisation of ASD. Further replication of these findings with other subsets of individuals with ASD is needed.

Back to the future: forget ultrasound and focus on clinical assessment in rheumatoid arthritis management.

Ultrasound (US) unquestionably improves many aspects of rheumatoid arthritis (RA) diagnosis and management, but no consensus has been reached regarding the optimal US methodology that should be used, and high levels of standardisation have not yet been attained. Current evidence from two randomised controlled trials does not support the US in directing treatment decisions. A return to the endorsement of clinical assessment and the adoption of T2T strategies aiming at ACR/EULAR remission still represent the standard of care for RA and should be pursued through appropriate educational programmes. Thus, for now, the major application of sonography in arthritis should have a focus on diagnostic and especially differential diagnostic aspects.

Implementation of the Edmonton Symptom Assessment System for Symptom Distress Screening at a Community Cancer Center: A Pilot Program.

BACKGROUND: Distress screening is mandated by the American College of Surgeons Commission on Cancer; however, there is limited literature on its impact in actual practice. We examined the impact of a pilot distress screening program on access to psychosocial care. METHODS: Edmonton Symptom Assessment System (ESAS) screening was routinely conducted at our community-based medical oncology program. Patients who screened positive for severe distress were sent to a social worker for triage and referred to the appropriate services if indicated. We compared the proportion of patients who had ESAS completed, the proportion of patients who screened positive, and the number of patients who had social work assessment and palliative care consultation over the preimplementation (September 2015), training (October/November 2015), and postimplementation (December 2015) periods. RESULTS: A total of 379, 328, and 465 cancer patients were included in the preimplementation, training, and postimplementation periods, respectively. The proportion of patients who completed ESAS increased over time (83% vs. 91% vs. 96%). Among the patients who had completed ESAS, between 11% and 13% were positive for severe distress, which remained stable over the three periods. We observed a significant increase in social work referrals for psychosocial assessment (21% vs. 71% vs. 79%). There was also a trend towards an increased number of palliative care referrals (12% vs. 20% vs. 28%). CONCLUSION: Our community-based cancer center implemented distress screening rapidly in a resource-limited setting, with a notable increase in symptom documentation and psychosocial referral. IMPLICATIONS FOR PRACTICE: The American College of Surgeons Commission on Cancer mandates distress screening; however, there is limited literature on how this process should be implemented and its impact on clinical practice. We used the Edmonton Symptom Assessment System for routine symptom distress screening in a community-based medical oncology program that provides care for an underserved population. Comparing before and after program implementation, we found an increase in the number of documentations of symptom burden and an increase in psychosocial referrals. Findings from this study may inform the implementation of routine symptom distress screening in cancer patients.

An investigation of changes in children's mental health in Wales between 2007/2008 and 2012/2013.

Improving children's mental wellbeing is a recognised public health priority, but evidence on recent trends is lacking. This study updates evidence on differences in child mental health since 2008 by comparing two nationally representative cohorts in Wales, UK. Parents of 4- to 12-year-old children completed the Strengths and Difficulties Questionnaire (SDQ). No significant differences were seen for younger girls between 2007/2008 and 2012/2013. There was a decrease in conduct, hyperactivity and total difficulties symptom scores and an increase in prosocial scores for boys and older girls. These findings suggest that rates of child mental health problems are stable or falling.

Using Search Engine Query Data to Explore the Epidemiology of Common Gastrointestinal Symptoms.

BACKGROUND: Internet searches are an increasingly used tool in medical research. To date, no studies have examined Google search data in relation to common gastrointestinal symptoms. AIMS: The aim of this study was to compare trends in Internet search volume with clinical datasets for common gastrointestinal symptoms. METHODS: Using Google Trends, we recorded relative changes in volume of searches related to dysphagia, vomiting, and diarrhea in the USA between January 2008 and January 2011. We queried the National Inpatient Sample (NIS) and the National Hospital Ambulatory Medical Care Survey (NHAMCS) during this time period and identified cases related to these symptoms. We assessed the correlation between Google Trends and these two clinical datasets, as well as examined seasonal variation trends. RESULTS: Changes to Google search volume for all three symptoms correlated significantly with changes to NIS output (dysphagia: r = 0.5, P = 0.002; diarrhea: r = 0.79, P < 0.001; vomiting: r = 0.76, P < 0.001). Both Google and NIS data showed that the prevalence of all three symptoms rose during the time period studied. On the other hand, the NHAMCS data trends during this time period did not correlate well with either the NIS or the Google data for any of the three symptoms studied. Both the NIS and Google data showed modest seasonal variation. CONCLUSIONS: Changes to the population burden of chronic GI symptoms may be tracked by monitoring changes to Google search engine query volume over time. These data demonstrate that the prevalence of common GI symptoms is rising over time.
