Clinical review: behavioral interventions to prevent childhood obesity: a systematic review and metaanalyses of randomized trials

CONTEXT

The efficacy of lifestyle interventions to encourage healthy lifestyle behaviors to prevent pediatric obesity remains unclear.

OBJECTIVE

Our objective was to summarize evidence on the efficacy of interventions aimed at changing lifestyle behaviors (increased physical activity, decreased sedentary activity, increased healthy dietary habits, and decreased unhealthy dietary habits) to prevent obesity.

DATA SOURCES

Data sources included librarian-designed searches of nine electronic databases, references from included studies and reviews (from inception until February 2006), and content expert recommendations.

STUDY SELECTION

Eligible studies were randomized trials enrolling children and adolescents assessing the impact of interventions on both lifestyle behaviors and body mass index (BMI).

DATA EXTRACTION

Two reviewers independently abstracted data on methodological quality, study characteristics, intervention components, and treatment effects.

DATA ANALYSIS

We conducted random-effects metaanalyses, quantified inconsistency using I(2), and conducted planned subgroup analyses for each examined outcome.

DATA SYNTHESIS

Regarding target behaviors, the pooled effect size for physical activity (22 comparisons; n = 9891 participants) was 0.12 [95% confidence interval (CI) = 0.04-0.20; I(2) = 63%], for sedentary activity (14 comparisons; n = 3003) was -0.29, (CI = -0.35 to -0.22; I(2) = 0%), for healthy dietary habits (14 comparisons, n = 5468) was 0.00 (CI = -0.20; 0.20; I(2) = 83%), and for unhealthy dietary habits (23 comparisons, n = 9578) was -0.20 (CI = -0.31 to -0.09; I(2) = 34%). The effect of these interventions on BMI (43 comparisons, n = 32,003) was trivial (-0.02; CI = -0.06-0.02; I(2) = 17%) compared with control. Trials with interventions lasting more than 6 months (vs. shorter trials) and trials with postintervention outcomes (vs. in-treatment outcomes) yielded marginally larger effects.

CONCLUSION

Pediatric obesity prevention programs caused small changes in target behaviors and no significant effect on BMI compared with control. Trials evaluating promising interventions applied over a long period, using responsive outcomes, with longer measurement timeframes are urgently needed.

Clinical review: treatment of pediatric obesity: a systematic review and meta-analysis of randomized trials

CONTEXT

The efficacy of treatments for pediatric obesity remains unclear.

OBJECTIVE

We performed a systematic review of randomized trials to estimate the efficacy of nonsurgical interventions for pediatric obesity.

DATA SOURCES

Librarian-designed search strategies of nine electronic databases from inception until February 2006, review of reference lists from published reviews, and content expert advice provided potentially eligible studies.

STUDY SELECTION

Eligible studies were randomized trials of overweight children and adolescents assessing the effect of nonsurgical interventions on obesity outcomes.

DATA EXTRACTION

Independently and in duplicate, reviewers assessed the quality of each trial and collected data on interventions and outcomes.

DATA SYNTHESIS

Of 76 eligible trials, 61 had complete data for meta-analysis. Short-term medications were effective, including sibutramine [random-effects pooled estimate of body mass index (BMI) loss of 2.4 kg/m(2) with a 95% confidence interval (CI) of 1.8-3.1; proportion of between-study inconsistency not due to chance (I(2)) = 30%] and orlistat (BMI loss = 0.7 kg/m(2); CI = 0.3-1.2; I(2) = 0%). Trials that measured the effect of physical activity on adiposity (i.e. percent body fat and fat-free mass) found a moderate treatment effect (effect size = -0.52; CI = -0.73 to -0.30; I(2) = 0%), whereas trials measuring the effect on BMI found no significant effect (effect size = -0.02; CI = -0.21 to 0.18; I(2) = 0%), but reporting bias may explain this finding. Combined lifestyle interventions (24 trials) led to small changes in BMI.

CONCLUSIONS

Limited evidence supports the short-term efficacy of medications and lifestyle interventions. The long-term efficacy and safety of pediatric obesity treatments remain unclear.

Systematic reviewers commonly contact study authors but do so with limited rigor

OBJECTIVES

Author contact can enhance the quality of systematic reviews. We conducted a systematic review of the practice of author contact in recently published systematic reviews to characterize its prevalence, quality, and results.

STUDY DESIGN AND SETTING

Eligible studies were systematic reviews of efficacy published in 2005-2006 in the 25 journals with the highest impact factor publishing systematic reviews in clinical medicine and the Cochrane Library, identified by searching MEDLINE, EMBASE, and the Cochrane Library. Two researchers determined whether and why reviewers contacted authors. To assess the accuracy of the abstracted data, we surveyed reviewers by e-mail.

RESULTS

Forty-six (50%) of the 93 eligible systematic reviews published in top journals and 46 (85%) of the 54 eligible Cochrane reviews reported contacting authors of eligible studies. Requests were made most commonly for missing information: 40 (76%) clinical medicine reviews and 45 (98%) Cochrane reviews. One hundred and nine of 147 (74%) reviewers responded to the survey, and reported a higher rate of author contact than apparent from the published record.

CONCLUSION

Although common, author contact is not a universal feature of systematic reviews published in top journals and the Cochrane Library. The conduct and reporting of author contact purpose, procedures, and results require improvement.

The cost-effectiveness of acetaminophen, NSAIDs, and selective COX-2 inhibitors in the treatment of symptomatic knee osteoarthritis

OBJECTIVE

The objective of this study was to conduct an economic evaluation of rofecoxib and celecoxib compared with high-dose acetaminophen or ibuprofen with and without misoprostol for patients with symptomatic knee osteoarthritis (OA).

METHODS

A decision analysis model was designed over 6 months using two measures of effectiveness: 1) number of upper gastrointestinal (GI) adverse events averted; and 2) number of patients who achieved perceptible pain relief. Separate analyses were conducted for all patients and for those who did not respond to acetaminophen. Outcome probabilities were obtained from a comprehensive review of randomized controlled trials and observational studies. Costs were derived from actual resource utilization of OA patients.

RESULTS

In terms of averting GI events, acetaminophen dominates the other options for an average risk patient population. For patients who did not respond to acetaminophen, rofecoxib had the lowest incremental cost-effectiveness ratio (ICER) per GI event avoided (32,000 US dollars) relative to ibuprofen. In terms of pain control, ibuprofen had an ICER of 610.77 US dollars per additional patient achieving minimal perceptible clinical improvement (MPCI) relative to acetaminophen, while rofecoxib had an ICER of 12,000 US dollars relative to ibuprofen. For patients who did not respond to acetaminophen and who are at high risk of developing an adverse GI event, rofecoxib dominates ibuprofen as the preferred alternative for both measures of effectiveness. One-way, two-way, and probabilistic sensitivity analyses established that these results were generally robust.

CONCLUSIONS

Our results suggest that for average-risk knee OA patients, acetaminophen dominates the other therapies in terms of cost per GI event averted. In terms of pain relief, cost-effectiveness acceptability curves indicate that if one values pain relief below 275 US dollars per patient achieving MPCI, acetaminophen is the therapy most likely to be optimal; between 275 US dollars and 14,150 US dollars, ibuprofen is most likely to be optimal; and above 14,150 US dollars, rofecoxib is most likely to be optimal.

Thyrotrophin receptor antibody characteristics in a woman with long-standing Hashimoto's who developed Graves' disease and pretibial myxoedema

CONTEXT

Sequential conversion of Hashimoto's thyroiditis (HT) to Graves' disease (GD) is uncommon. Distinct immune paradigms, paucity of functioning tissue in long-standing HT, and infrequent conversion of blocking (TBAb) to stimulating (TSAb) thyrotrophin receptor antibody (TRAb) may account for this. Molecular and crystal structure analysis helps delineate TSH receptor (TSHR)/TRAb interactions in detail. Such 'fingerprinting' helps determine the behaviour and characteristics of TRAb in longitudinal studies.

PATIENT

An 80-year-old woman taking thyroxine for long-standing HT became hyperthyroid. This persisted despite thyroxine withdrawal - free T3 was 7·3 pmol/l (2·6-5·7) and TSH < 0·01 mU/l (0·2-4·5) and TRAb highly positive. She had a goitre (ultrasound - HT), pretibial myxoedema, with mild inactive Graves' orbitopathy. She had RAI treatment and is on thyroxine replacement.

MEASUREMENTS AND RESULTS

Blood samples at presentation (A) and 1 year (B) showed high TSAb and TPOAb activity but no TBAb. Experiments involving TSHR mutations confirmed that (i) TRAb had stable characteristics over 1 year; (ii) TSHR mutation R255D caused complete inhibition and (iii) R109A caused marked reduction of cAMP production by M22 (TSHR-stimulating human monoclonal antibody) and A and B; (iv) mutations R80A, E107A and K129A while affecting M22 had little effect on A and B.

CONCLUSIONS

The reasons for an immunological paradigm shift in this elderly woman remain speculative. We believe that de-novo TSAb synthesis occurred converting her long-standing HT to GD although the mechanisms responsible remain unexplained. TRAb analysis confirmed stable autoantibody characteristics over 1 year and variable effects of TSHR mutations on TRAb and M22 function.

Provider satisfaction in clinical encounters with ethnic immigrant patients

OBJECTIVE

To determine whether physicians' satisfaction in clinical encounters with ethnic immigrant patients differs from satisfaction in clinical encounters with white patients in the local community.

PATIENTS AND METHODS

Postvisit assessments from primary care physicians were collected for matched pairs of ethnic and control patients at the Mayo Clinic in Rochester, Minn, during a 10-week study (April 2-June 9, 2001). Ethnic patients were defined as first-generation Somalian, Cambodian, and Hispanic immigrants. Control patients were American-born white patients who were seen by the same physician and matched to the ethnic patients in age, sex, and type of visit. T tests and Hotelling T2 tests were used to analyze differences in physician responses between groups; regression analysis was used to identify the relationship between physicians' satisfaction and ethnicity in the presence of covariates.

RESULTS

Physicians were considerably less satisfied with ethnic patient visits compared with control patient visits. Larger differences in satisfaction were reported in the areas of patient efforts with disease prevention and management of chronic diseases. Smaller differences in satisfaction were reported for issues related to communication and cultural beliefs and practices. These differences persisted after controlling for patient demographics, physician, and visit characteristics.

CONCLUSIONS

Patients' ethnicity affects physician satisfaction with clinical encounters, particularly in the delivery of preventive care and chronic disease management.

Developing an Educational Intervention to Address Financial Hardship in Cancer Patients

Objective

To develop an educational intervention to empower patients to manage their financial health better.

Participants and Methods

This study was conducted from September 1, 2017, to January 31, 2019. Focus groups were held with social workers, case managers, and patient financial service staff and interviews were conducted with patients and caregivers to inform the content, delivery format, and timing of an intervention for mitigating financial hardship from treatment (phase 1). Based on qualitative data, theories of adult learning, and a review of the literature, we created an educational presentation to be delivered in a classroom setting. Two patient focus groups were then held for feedback on the presentation (phase 2).

Results

In phase 1, both patients and allied health care staff providers believed that an educational intervention about financial aspects of care early during treatment would help them cope and plan better. Participants' suggestions for the intervention's content included billing information, insurance, authorization processes, employment policies related to health care and disability benefits, and alternative financial resources. Based on these suggestions, a preliminary educational presentation was developed with 3 main themes: insurance issues, employment issues, and financial health. Phase 2 focus group participants suggested refinement of the presentation, including targeting specific groups, adding graphics, and more information about resources.

Conclusion

Our study provides the basis for a patient-centered education module for emotional, instrumental, and informational support for financial distress for use in a clinical setting.

Acute respiratory distress syndrome with pulmonary calcification in two patients with B cell malignancies

Two patients, one with B cell lymphoma and hypercalcemia and the other with multiple myeloma and hypercalcemia developed acute progressive respiratory insufficiency characteristic of the adult respiratory distress syndrome (ARDS). Both were intubated and placed on mechanical ventilation. Lung compliance deteriorated and became refractory to mechanical inflation. Examination of the lungs at post mortem examination disclosed widespread calcification within alveolar septa and diffuse alveolar damage with hyaline membrane formation consistent with ARDS. Although ARDS has been described with lymphomatous involvement of the lungs, its development in association with metastatic calcification in B cell malignancy has not been previously reported.

Can a random serum cortisol reduce the need for short synacthen tests in acute medical admissions?

BACKGROUND

Short synacthen tests (SSTs) are frequently performed in medical inpatients with suspected adrenocortical insufficiency. The utility of a random or baseline serum cortisol in this setting is unclear. We determined random cortisol thresholds that safely preclude SSTs in acute medical admissions.

METHODS

We analysed SSTs in acute non-critically ill general medical patients (n = 166, median age 66, range 15-94 y; men 48%, women 52%). The SST was defined according to the 30-min cortisol as 'pass' (>550 nmol/L) or 'fail' (< or =550 nmol/L). Receiver operating characteristics (ROC) curves were generated to determine the predictive value of the basal cortisol for a failed SST.

RESULTS

Of 166 SSTs, a pass was seen in 127 (76.5%) tests, while 39 (23.5%) tests failed the SST. ROC curves showed that no single cut-off point of the baseline cortisol was adequately both sensitive and specific for failing the SST despite a good overall predictive value (area under curve 0.94; 95% confidence interval 0.89-0.98). A basal cortisol <420 nmol/L had 100% sensitivity and 54% specificity for failing the SST, while a basal cortisol <142 nmol/L had 100% specificity and 35% sensitivity. Restricting the SST to patients with a basal cortisol <420 nmol/L would have prevented 44% of SSTs while correctly identifying all patients who failed the SST.

CONCLUSION

A baseline serum cortisol may prevent unnecessary SSTs in medical inpatients with suspected adrenocortical insufficiency. However, SSTs are still indicated in patients with random cortisol <420 nmol/L, or where the suspicion of adrenal insufficiency is compelling.

Cost Conversations About Anticoagulation Between Patients With Atrial Fibrillation and Their Clinicians: A Secondary Analysis of a Randomized Clinical Trial

IMPORTANCE

How patients with atrial fibrillation (AF) and their clinicians consider cost in forming care plans remains unknown.

OBJECTIVE

To identify factors that inform conversations regarding costs of anticoagulants for treatment of AF between patients and clinicians and outcomes associated with these conversations.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study of recorded encounters and participant surveys at 5 US medical centers (including academic, community, and safety-net centers) from the SDM4AFib randomized trial compared standard AF care with and without use of a shared decision-making (SDM) tool. Included patients were considering anticoagulation treatment and were recruited by their clinicians between January 30, 2017, and June 27, 2019. Data were analyzed between August and November 2019.

MAIN OUTCOMES AND MEASURES

The incidence of and factors associated with cost conversations, and the association of cost conversations with patients' consideration of treatment cost burden and their choice of anticoagulation.

RESULTS

A total of 830 encounters (out of 922 enrolled participants) were recorded. Patients' mean (SD) age was 71.0 (10.4) years; 511 patients (61.6%) were men, 704 (86.0%) were White, 303 (40.9%) earned between $40 000 and $99 999 in annual income, and 657 (79.2%) were receiving anticoagulants. Clinicians' mean (SD) age was 44.8 (13.2) years; 75 clinicians (53.2%) were men, and 111 (76%) practiced as physicians, with approximately half (69 [48.9%]) specializing in either internal medicine or cardiology. Cost conversations occurred in 639 encounters (77.0%) and were more likely in the SDM arm (378 [90%] vs 261 [64%]; OR, 9.69; 95% CI, 5.77-16.29). In multivariable analysis, cost conversations were more likely to occur with female clinicians (66 [47%]; OR, 2.85; 95% CI, 1.21-6.71); consultants vs in-training clinicians (113 [75%]; OR, 4.0; 95% CI, 1.4-11.1); clinicians practicing family medicine (24 [16%]; OR, 12.12; 95% CI, 2.75-53.38]), internal medicine (35 [23%]; OR, 3.82; 95% CI, 1.25-11.70), or other clinicians (21 [14%]; OR, 4.90; 95% CI, 1.32-18.16) when compared with cardiologists; and for patients with an annual household income between $40 000 and $99 999 (249 [82.2%]; OR, 1.86; 95% CI, 1.05-3.29) compared with income below $40 000 or above $99 999. More patients who had cost conversations reported cost as a factor in their decision (244 [89.1%] vs 327 [69.0%]; OR 3.66; 95% CI, 2.43-5.50), but cost conversations were not associated with the choice of anticoagulation agent.

CONCLUSIONS AND RELEVANCE

Cost conversations were common, particularly for middle-income patients and with female and consultant-level primary care clinicians, as well as in encounters using an SDM tool; they were associated with patients' consideration of treatment cost burden but not final treatment choice. With increasing costs of care passed on to patients, these findings can inform efforts to promote cost conversations in practice.

Association of Rurality and Neighborhood Level Socioeconomic Deprivation with Perioperative Health Status in Total Joint Arthroplasty Patients: Analysis from a Large, Tertiary Care Hospital

BACKGROUND

Individual socioeconomic status (SES) is associated with disparities in access to care and worse outcomes in total joint arthroplasty (TJA). Neighborhood-level SES measures are sometimes used as a proxy for individual-level SES, but the validity of this approach is unknown. We examined neighborhood level SES and rurality on perioperative health status in TJA.

METHODS

The study population comprised 46,828 TJA surgeries performed at a tertiary care hospital. Community area deprivation index (ADI) was derived from the 2015 American Census Survey. Logistic regression was used to examine perioperative characteristics by ADI and rurality.

RESULTS

Compared to patients from the least deprived neighborhoods, patients from the most deprived neighborhoods were likely to be female (odds ratioOR 1.46, 95% confidence interval CI: 1.33-1.61), non-white (OR 1.36, 95% CI: 1.13-1.64), with education high school or less (OR 4.85, 95% CI: 4.35-5.41), be current smokers (OR 2.20, 95% CI: 1.61-2.49), have BMI>30 kg/m² (OR 1.43, 95% CI: 1.30-1.57), more limitation on instrumental activities of daily living (OR 1.75, 95% CI: 1.55-1.97) and American Society of Anesthesiologists (ASA) score > II (OR 2.0, 95% CI: 1.11-1.37). There was a progressive association between the degree of area level deprivation with preexisting comorbidities. Patients from rural communities were more likely to be male, white, have body mass index (BMI)>30 kg/m² and lower education levels. However, rurality was either not associated or negatively associated with comorbidities.

CONCLUSION

TJA patients from lower SES neighborhoods have worse behavioral risk factors and higher comorbidity burden than patients from higher SES neighborhoods. Patients from rural communities have worse behavioral risk factors but not comorbidities.

Using Shared Decision-Making Tools and Patient-Clinician Conversations About Costs

Objective

To determine how shared decision-making (SDM) tools used during clinical encounters that raise cost as an issue impact the incidence of cost conversations between patients and clinicians.

Patients and Methods

A randomly selected set of 220 video recordings of clinical encounters were analyzed. Videos were obtained from eight practice-based randomized clinical trials and one quasi-randomized clinical trial (pre- and post-) comparing care with and without SDM tools. The secondary analysis took place in 2018 from trials ran between 2007 and 2015.

Results

Most patient participants were white (85%), educated (38% completed college), middle-aged (mean age 56 years), and female (61%). There were 105 encounters with and 115 without the SDM tool. Encounters with SDM tools were more likely to include both general cost conversations (62% vs 36%, odds ratio [OR]: 9.6; 95% CI: 4 to 26) as well as conversations on medication costs specifically (89% vs 51%, P=.01). However, clinicians using SDM tools were less likely to address cost issues during the encounter (37% vs 51%, P=.04). Encounters with patients with less than a college degree were also associated with a higher incidence of cost conversations.

Conclusion

Using SDM tools that raise cost as an issue increased the occurrence of cost conversations but was less likely to address cost issues or offer potential solutions to patients’ cost concerns. This result suggests that SDM tools used during the consultation can trigger cost conversations but are insufficient to support them.

ABLE to support patient financial capacity: A qualitative analysis of cost conversations in clinical encounters

OBJECTIVE

To explore how costs of care are discussed in real clinical encounters and what humanistic elements support them.

METHODS

A qualitative thematic analysis of 41 purposively selected transcripts of video-recorded clinical encounters from trials run between 2007 and 2015. Videos were obtained from a corpus of 220 randomly selected videos from 8 practice-based randomized trials and 1 pre-post prospective study comparing care with and without shared decision making (SDM) tools.

RESULTS

Our qualitative analysis identified two major themes: the first, Space Needed for Cost Conversations, describes patients' needs regarding their financial capacity. The second, Caring Responses, describes humanistic elements that patients and clinicians can bring to clinical encounters to include good quality cost conversations.

CONCLUSION

Our findings suggest that strengthening patient-clinician human connections, focusing on imbalances between patient resources and burdens, and providing space to allow potentially unexpected cost discussions to emerge may best support high quality cost conversations and tailored care plans.

PRACTICE IMPLICATIONS

We recommend clinicians consider 4 aspects of communication, represented by the mnemonic ABLE: Ask questions, Be kind and acknowledge emotions, Listen for indirect signals and (discuss with) Every patient. Future research should evaluate the practicality of these recommendations, along with system-level improvements to support implementation of our recommendations.

Nephrogenic diabetes insipidus partially responsive to oral desmopressin in a subject with lithium-induced multiple endocrinopathy

Lithium (Li) may cause multiple endocrinopathies, including hypercalcaemia, thyroid dysfunction and nephrogenic diabetes insipidus (NDI), but rarely in the same patient. The management of NDI remains a challenge. We report on a patient on long-term Li who had simultaneous NDI (paired serum and urine samples had abnormal osmolalities, typical of NDI, and treatment with parenteral desmopressin failed to affect urinary volume and serum osmolality), 'destructive' thyroiditis (hyperthyroidism, absent radioiodine uptake and absent thyrotrophin receptor antibodies) and primary hyperparathyroidism (compatible biochemistry, urine calcium excluding 'set point' anomalies and hypocalciuric hypercalcaemia, and normal parathyroid imaging). The thyroiditis resolved spontaneously and hypercalcaemia responded to reduction of Li dose. The NDI was unresponsive to amiloride, thiazides and ibuprofen in combination. However, urine output was reduced by 50% when a high dose of oral desmopressin was given. We conclude that Li-induced multiple endocrinopathy remains rare and, although NDI is difficult to manage, high dose oral desmopressin should be tried when other medications fail.

Implementation strategies for interventions to improve the management of chronic kidney disease (CKD) by primary care clinicians: protocol for a systematic review

INTRODUCTION

There is a considerable implementation gap in managing early stage chronic kidney disease (CKD) in primary care despite the high prevalence and risk for increased morbidity and mortality associated with CKD. This systematic review aims to synthesise the evidence of efficacy of implementation interventions aimed at primary care practitioners (PCPs) to improve CKD identification and management. We further aim to describe the interventions' behavioural change components.

METHODS AND ANALYSIS

We will conduct a systematic review of studies from 2000 to October 2017 that evaluate implementation interventions targeting PCPs and which include at least one clinically meaningful CKD outcome. We will search several electronic data bases and conduct reference mining of related systematic reviews and publications. An interdisciplinary team will independently and in duplicate, screen publications, extract data and assess the risk of bias. Clinical outcomes will include all clinically meaningful medical management outcomes relevant to CKD management in primary care such as blood pressure, chronic heart disease and diabetes target achievements. Quantitative evidence synthesis will be performed, where possible. Planned subgroup analyses include by (1) study design, (2) length of follow-up, (3) type of intervention, (4) type of implementation strategy, (5) whether a behavioural or implementation theory was used to guide study, (6) baseline CKD severity, (7) patient minority status, (8) study location and (9) academic setting or not.

ETHICS AND DISSEMINATION

Approval by research ethics board is not required since the review will only include published and publicly accessible data. Review findings will inform a future trial of an intervention to promote uptake of CKD diagnosis and treatment guidelines in our primary care setting and the development of complementary tools to support its successful adoption and implementation. We will publish our findings in a peer-reviewed journal and develop accessible summaries of the results.

Longitudinal factors associated with increased alcohol consumption in adults during the COVID-19 pandemic

Background: Alcohol is the most abused substance among adults in the United States. The COVID-19 pandemic impacted patterns of alcohol use, but data are conflicting, and previous studies are largely limited to cross-sectional analyses.Objective: This study aimed to longitudinally assess sociodemographic and psychological correlates of changes in three patterns of alcohol use (number of alcoholic drinks, drinking regularity, and binge drinking) during COVID-19.Methods: We studied changes in self-reported drinking behaviors in 222,195 Mayo Clinic patients over 21 years of age (58.1% female and 41.9% male) between April 1, 2019, and March 30, 2021. Logistic regression models were used to estimate associations between patient characteristics and change in alcohol consumption.Results: Sociodemographically younger age, White race, having a college degree, and living in a rural area were associated with increased alcohol use regularity (all p < .05). Younger age, male, White, high-school education or less, living in a more deprived neighborhood, smoking, and living in a rural area were associated with increases in number of alcohol drinks (all p ≤ .04) and binge drinking (all p ≤ .01). Increased anxiety scores were associated with increased number of drinks, while depression severity was associated with both increased drinking regularity and increased number of drinks (all p ≤ .02) independent of sociodemographic characteristics.Conclusion: Our study showed that both sociodemographic and psychological characteristics were associated with increased alcohol consumption patterns during the COVID-19 pandemic. Our study highlights specific target groups previously not described in the literature for alcohol interventions based on sociodemographic and psychological characteristics.

Managing thymic enlargement in Graves' disease

Thymic enlargement (TE) in Graves' disease (GD) is often diagnosed incidentally when chest imaging is done for unrelated reasons. This is becoming more common as the frequency of chest imaging increases. There are currently no clear guidelines for managing TE in GD. Subject 1 is a 36-year-old female who presented with weight loss, increased thirst and passage of urine and postural symptoms. Investigations confirmed GD, non-PTH-dependent hypercalcaemia and Addison's disease (AD). CT scans to exclude underlying malignancy showed TE but normal viscera. A diagnosis of hypercalcaemia due to GD and AD was made. Subject 2, a 52-year-old female, was investigated for recurrent chest infections, haemoptysis and weight loss. CT thorax to exclude chest malignancy, showed TE. Planned thoracotomy was postponed when investigations confirmed GD. Subject 3 is a 47-year-old female who presented with breathlessness, chest pain and shakiness. Investigations confirmed T3 toxicosis due to GD. A CT pulmonary angiogram to exclude pulmonary embolism showed TE. The CT appearances in all three subjects were consistent with benign TE. These subjects were given appropriate endocrine treatment only (without biopsy or thymectomy) as CT appearances showed the following appearances of benign TE - arrowhead shape, straight regular margins, absence of calcification and cyst formation and radiodensity equal to surrounding muscle. Furthermore, interval scans confirmed thymic regression of over 60% in 6 months after endocrine control. In subjects with CT appearances consistent with benign TE, a conservative policy with interval CT scans at 6 months after endocrine control will prevent inappropriate surgical intervention. Learning points: Chest imaging is common in modern clinical practice and incidental anterior mediastinal abnormalities are therefore diagnosed frequently. Thymic enlargement (TE) associated with Graves' disease (GD) is occasionally seen in view of the above. There is no validated strategy to manage TE in GD at present. However, CT (or MRI) scan features of the thymus may help characterise benign TE, and such subjects do not require thymic biopsy or surgery at presentation. In them, an expectant 'wait and see' policy is recommended with GD treatment only, as the thymus will show significant regression 6 months after endocrine control.
