An exploratory analysis of the impact of the COVID-19 pandemic on pediatric type 1 diabetes mellitus patient outcomes: A single-center study.

Background: The COVID-19 pandemic led to substantial shifts in pediatric diabetes care delivery to virtual and hybrid models. It is unclear if these changes in care delivery impacted short-term patient outcomes. Objectives: We aimed to explore glycemic control and other diabetes-related outcomes in children living with Type 1 Diabetes Mellitus (T1DM) during the first year of the COVID-19 pandemic at a tertiary pediatric academic center in Canada. Subjects: Patients <18 years of age with a confirmed diagnosis of T1DM for at least one year were included. Methods: This was a retrospective chart review. We compared data from two years pre-pandemic (March 15, 2018-March 14, 2020) to the first year of the pandemic (March 15, 2020-March 14, 2021). The data assessed included glycemic control [Hemoglobin A1c (HbA1c)], diabetic ketoacidosis (DKA), hospital attendance and hospitalizations, hypoglycemia, and hyperglycemia. The generalized estimating equation (GEE) analysis was used to model potential factors affecting the HbA1c and diabetes-related morbidities. Multiple imputations were conducted as a sensitivity analysis. Results: There were 346 eligible patients included in the study. The HbA1c remained stable during the pandemic compared to the pre-pandemic phase (MD-0.14, 95% CI, -0.28, 0.01; p = 0.058). The pandemic saw an increase in the number of newly diagnosed patients (X2 = 16.52, p < 0.001) and a higher number of newly diagnosed patients presenting in DKA (X2 = 12.94, p < 0.001). In patients with established diabetes, there was an increase in hyperglycemia (OR1.38, 95% CI, 1.12,1.71; p = 0.003) and reduced DKA (OR 0.30, 95% CI, 0.12,0.73; p = 0.009) during the pandemic compared to the pre-pandemic phase. Stable rates of hospitalization (OR0.57, 95% CI, 0.31,1.04, p = 0.068) and hypoglycemia (OR1.11, 95% CI, 0.83,1.49; p = 0.484) were noted. These results were retained in the sensitivity analysis. Conclusions: Glycemic control in children with T1DM remained stable during the first year of the pandemic. There were more newly diagnosed patients during the pandemic compared to the pre-pandemic phase, and more of these new patients presented in DKA. The latter presentation was reduced in those with established diabetes during the same period.Further studies are needed to assess the ongoing impact of the COVID-19 pandemic on T1DM care pathways and outcomes to allow children, families, and diabetes teams to personalize choices of care models.

Behavioral interventions for improving sleep outcomes in menopausal women: a systematic review and meta-analysis.

IMPORTANCE: Perimenopausal and postmenopausal women commonly report sleep disruption and insomnia. Behavioral interventions may be safe alternatives for patients who are unwilling to begin pharmacological treatments because of adverse effects, contraindications, or personal preference. OBJECTIVE: The primary objective is to assess the efficacy of behavioral interventions on sleep outcomes among perimenopausal and postmenopausal women, as measured using standardized scales and objective methods (polysomnography, actigraphy). The secondary objective is to evaluate the safety of these methods through occurrence of adverse events. EVIDENCE REVIEW: Searches were performed within MEDLINE (OVID interface, 1946 onward), Embase (OVID interface, 1974 onward), Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, and Web of Science (Core collection) using a search strategy developed in consultation with a health sciences librarian. Title/abstract and full-text screenings were performed in duplicate, and relevant studies were selected based on inclusion and exclusion criteria set to identify randomized controlled trials evaluating the effects of behavioral interventions on sleep quality. Risk of bias assessments were done using the Cochrane Risk of Bias 2 tool, and the Grading of Recommendations Assessment, Development and Evaluation approach was used to assess the certainty of the body of evidence. Data were pooled in a meta-analysis using a random-effects model. FINDINGS: Nineteen articles reporting results from 16 randomized controlled trials were included, representing a total of 2,108 perimenopausal and postmenopausal women. Overall, behavioral interventions showed a statistically significant effect on sleep outcomes (standardized mean difference [SMD], -0.62; 95% confidence interval [CI], -0.88 to -0.35; I2 = 93.4%). Subgroup analyses revealed that cognitive behavioral therapy (SMD, -0.40; 95% CI, -0.70 to -0.11; I2 = 72.7%), physical exercise (SMD, -0.57; 95% CI, -0.94 to -0.21; I2 = 94.0%), and mindfulness/relaxation (SMD, -1.28; 95% CI, -2.20 to -0.37; I2 = 96.0%) improved sleep, as measured using both subjective (eg, Pittsburg Sleep Quality Index) and objective measures. Low-intensity (SMD, -0.91; 95% CI, -1.59 to -0.24; I2 = 96.8) and moderate-intensity exercise (SMD, -0.21; 95% CI, -0.34 to -0.08; I2 = 0.0%) also improved sleep outcomes. No serious adverse events were reported. Overall risk of bias ranged from some concern to serious, and the certainty of the body of evidence was assessed to be of very low quality. CONCLUSIONS AND RELEVANCE: This meta-analysis provides evidence that behavioral interventions, specifically, cognitive behavioral therapy, physical exercise, and mindfulness/relaxation, are effective treatments for improving sleep outcomes among perimenopausal and postmenopausal women.

Impact of SARS-CoV-2 pandemic on the mental and physical health of children enrolled in a paediatric weight management clinic.

Background: Obesity is a global public health concern. Given the widespread disruption caused by the SARS-CoV-2 pandemic, it is important to evaluate its impact on children with chronic health conditions. This study examines the health of paediatric patients with obesity enrolled in a tertiary hospital weight management program, before and 1 year into the COVID-19 pandemic. Methods: This is a retrospective chart review of patients aged 2 to 17 years enrolled in a paediatric weight management clinic. Mental health outcomes (i.e., new referrals to psychologist, social work, eating disorder program, incidence of dysregulated eating, suicidal ideation, and/or self-harm) and physical health (anthropometric measures) were compared before and 1 year into the pandemic. Results: Among the 334 children seen in either period, there was an increase in referrals to psychologist (12.4% versus 26.5%; P=0.002) and the composite mental health outcome (17.2% versus 30.2%; P=0.005) during the pandemic compared with pre-pandemic. In a subset of children (n=30) with anthropometric measures in both periods, there was a lower rate of decline in BMIz score (-1.5 [2.00] versus -0.3 [0.73]/year; P=0.002) and an increase in adiposity (-0.8 [4.64] versus 2.7 [5.54]%/year; P=0.043) during the pandemic. Discussion: The pandemic has impacted the mental and physical health of children with obesity engaged in a weight management clinic. While our study provides evidence of a negative impact on mental health outcomes and less improvement in anthropometric measures, future research when patients return to in-person care will enable further examination of our findings with additional objective measures.

Effectiveness and safety of steady versus intermittent high dose vitamin D supplementation for the prevention of falls and fractures among adults: a protocol for systematic review and network meta-analysis.

INTRODUCTION: Clinical trials and systematic reviews of trials involving vitamin D supplementation have mainly focused on defining the optimal amount of vitamin D dosage. However, the comparative effectiveness of different dosing schedules (ie, daily vs bolus dosing schedule) has been largely unexplored; and currently, there is no consensus regarding the optimal vitamin D dosing schedule. Our objective is to conduct a systematic review and network meta-analysis (NMA) to evaluate the comparative effectiveness and safety of steady (eg, daily, weekly) and intermittent high-dose (eg, monthly, yearly) vitamin D dosing schedules; and to determine the effectiveness of the various dosing schedules and combinations of treatments. METHODS AND ANALYSIS: We will conduct a systematic search and review of literature from major medical databases (MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov) involving studies that compare vitamin D supplementation alone or in combination with calcium. Only randomised controlled trials (RCTs) will be considered. We will, however, consider various settings (eg, community, institutional care) and study designs (eg, cluster RCTs, cross-over trials). Our primary outcomes include falls and fractures including hip-fracture and non-vertebral fractures. Secondary outcomes will include muscle strength, physical performance, gait and mobility limitation. A Bayesian NMA will be conducted, and the results will be presented in the form of treatment effect estimates and ranking probabilities, with corresponding CIs. Pairwise meta-analysis will also be conducted for studies reporting head-to-head comparisons. Subgroup analysis will be performed with respect to pre-determined subgroups; including vitamin D status as measured by serum 25-hydroxyvitamin D levels, age and follow-up time. Sensitivity analysis will also be performed with respect to risk of bias. ETHICS AND DISSEMINATION: This study is a systematic review and meta-analysis of published RCTs; therefore, no ethical approval is required. Results will be disseminated through open access peer-reviewed publications. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42018112662.

A critical appraisal of chronic kidney disease mineral and bone disorders clinical practice guidelines using the AGREE II instrument.

BACKGROUND: Patients with chronic kidney disease mineral and bone disorders (CKD-MBD) suffer high rates of morbidity and mortality, in particular related to bone and cardiovascular outcomes. The management of CKD-MBD remains challenging. The objective of this systematic survey is to critically appraise clinical practice guidelines (CPGs) addressing CKD-MBD. METHODS/DESIGN: Data sources included MEDLINE, EMBASE, the National Guideline Clearinghouse, Guideline International Network and Turning Research into Practice up to May 2016. Teams of two reviewers, independently and in duplicate, screened titles and abstracts and potentially eligible full text reports to determine eligibility and subsequently appraised the guidelines using the Advancing Guideline Development, Reporting and Evaluation in Health Care instrument II (AGREE). RESULTS: Sixteen CPGs published from 2003 to 2015 addressing the diagnosis and management of CKD-MBD in adult patients (11 English, two Spanish, one Italian, one Portuguese and one Slovak) proved eligible. The National Institute for Health and Care Excellence guideline performed best with respect to AGREE II criteria; only three other CPGs warranted high scores on all domains. All other guidelines received scores of under 60% on one or more domains. Major discrepancies in recommendations were not, however, present, and we found no association between quality of CPGs which was not associated with resulting recommendations. CONCLUSIONS: Most guidelines assessing CKD-MBD suffer from serious shortcomings using AGREE criteria although limitations with respect to AGREE criteria do not necessarily lead to inappropriate recommendations.
