A growing body of evidence indicates that patients with obesity are disproportionately affected with a severe form of SARS-CoV-2 infection and may experience resultant higher mortality. The aim of this study was to determine the association of prior metabolic surgery with severity of SARSCoV-2 infection in patients with severe obesity. This study is a retrospective, matched-cohort analysis of a prospective, observational, institutional review board–approved clinical registry of all patients tested for SARS-CoV-2 infection. The study population included a total of 363 patients, including 33 individuals who had metabolic surgery and 330 matched patients who tested positive. Results indicate that a history of metabolic surgery is associated with lower severity of SARSCoV-2 infection in patients with severe obesity, as manifested by lower risks of hospital and ICU admission. Authors conclude that prior metabolic surgery with subsequent weight loss and improvement of metabolic abnormalities could potentially reduce morbidity from SARS-CoV-2 infection.
Abstract
BACKGROUND Obesity is a risk factor for poor clinical outcomes in patients with coronavirus disease 2019 (COVID-19). OBJECTIVES To investigate the relationship between prior metabolic surgery and the severity of COVID-19 in patients with severe obesity. SETTING Cleveland Clinic Health System in the United States. METHODS Among 4365 patients who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) between March 8, 2020 and July 22, 2020 in the Cleveland Clinic Health System, 33 patients were identified who had a prior history of metabolic surgery. The surgical patients were propensity matched 1:10 to nonsurgical patients to assemble a cohort of control patients (n = 330) with a body mass index (BMI) ≥ 40 kg/m2 at the time of SARS-CoV-2 testing. The primary endpoint was the rate of hospital admission. The exploratory endpoints included admission to the intensive care unit (ICU), need for mechanical ventilation and dialysis during index hospitalization, and mortality. After propensity score matching, outcomes were compared in univariate and multivariate regression models. RESULTS The average BMI of the surgical group was 49.1 ± 8.8 kg/m2 before metabolic surgery and was down to 37.2 ± 7.1 at the time of SARS-CoV-2 testing, compared with the control group's BMI of 46.7 ± 6.4 kg/m2. In the univariate analysis, 6 (18.2%) patients in the metabolic surgery group and 139 (42.1%) patients in the control group were admitted to the hospital (P = .013). In the multivariate analysis, a prior history of metabolic surgery was associated with a lower hospital admission rate compared with control patients with obesity (odds ratio, 0.31; 95% confidence interval, 0.11-0.88; P = .028). While none of the 4 exploratory outcomes occurred in the metabolic surgery group, 43 (13.0%) patients in the control group required ICU admission (P = .021), 22 (6.7%) required mechanical ventilation, 5 (1.5%) required dialysis, and 8 (2.4%) patients died. CONCLUSION Prior metabolic surgery with subsequent weight loss and improvement of metabolic abnormalities was associated with lower rates of hospital and ICU admission in patients with obesity who became infected with SARS-CoV-2. Confirmation of these findings will require larger studies.

Heart failure (HF) is a severe and progressive condition with poor prognosis. Obesity is a risk factor for HF. The aim of this study was to investigate the impact of change in physical activity or change in body mass index on the risk of later developing HF in women without a previous diagnosis of HF. This study is prospective longitudinal study which includes 1749 healthy women from the Prospective Population Study of Women in Gothenburg. Results indicate that gaining weight in early middle age is more harmful than gaining weight later in life, with regard to the risk of developing HF later in life. Furthermore, reduced risk of future HF in healthy women may be achieved by remaining physically active from young middle age and throughout life or by increasing the level of physical activity. Authors conclude that the role of physical activity in preventing the development of obesity must be taken into account.
Abstract
Objective: To longitudinally evaluate the impact of change in physical activity or change in body mass index (BMI) over time on the risk of developing heart failure (HF) in women without a previous diagnosis of HF.Design and setting: Longitudinal, observational, prospective study of women in Gothenburg, Sweden. Data on BMI and level of physical activity were collected from examinations 1968-1992 and hospital diagnoses and mortality data were ascertained from 1980 to 2012.Subjects: Data were obtained from 1749 women included in the Prospective Population Study of Women in Gothenburg.Main outcome measures: Hazard ratio (HR) for HF was calculated, using a Cox regression model.Results: Women with stable high physical activity during 1968-1980 and 1980-1992 reduced their risk of subsequent HF compared to the non-active women (for 1968-1980 HR 0.66, 95% Confidence Interval (CI) 0.44-0.99 and for 1980-1992 HR 0.47, 95% CI 0.29-0.74). Women with increasing levels of physical activity during 1980-1992 reduced their risk of HF compared to the non-active women (HR 0.40, 95% CI 0.22-0.72). Increase in BMI from overweight to obesity during 1968-1980 predicted increased risk of developing HF (HR 1.93, 95% CI 1.18-3.14).Conclusions: Reduced risk of future HF in healthy women may be achieved by remaining physically active from young middle age and throughout life or by increasing the level of physical activity. This is particularly important for sedentary women in middle age. The role of physical activity in preventing the development of obesity must be taken into account.Key pointsA sedentary lifestyle and obesity are risk factors for developing heart failure (HF) in women.The risk of developing HF may be reduced by increasing the level of activity in sedentary middle-aged women.For younger women, avoiding obesity is most important to reduce the risk of later HF.Primary care has a key role in guiding women towards the most effective lifestyle changes to prevent development of HF.

The pandemic of the coronavirus SARS-CoV-2 (COVID-19) has caused significant disruption in everyday lifestyle. The aim if this study was to evaluate the changes in weight and dietary habits in a sample of individuals with obesity attending the Obesity Unit after 1 month of enforced lockdown. This is an observational retrospective study were patients followed a 12-month multidisciplinary weight loss program. Results showed that patients with obesity attending an Obesity Unit in Northern Italy showed a ≈1.5 kg self-reported weight gain after the first month of lockdown. Lower education level, self-reported anxiety/depression, and not paying attention to the healthiness of food choices were significantly associated with weight and body mass index increase. Authors conclude that the adverse mental burden linked to the COVID-19 pandemic might be associated with their increased weight.
Abstract
Our aim is evaluating the changes in weight and dietary habits in a sample of outpatients with obesity after 1 month of enforced lockdown during the COVID-19 pandemic in Northern Italy. In this observational retrospective study, the patients of our Obesity Unit were invited to answer to a 12-question multiple-choice questionnaire relative to weight changes, working activity, exercise, dietary habits, and conditions potentially impacting on nutritional choices. A multivariate regression analysis was performed to evaluate the associations among weight/BMI changes and the analyzed variables. A total of 150 subjects (91.5%) completed the questionnaire. Mean self-reported weight gain was ≈1.5 kg (p < 0.001). Lower exercise, self-reported boredom/solitude, anxiety/depression, enhanced eating, consumption of snacks, unhealthy foods, cereals, and sweets were correlated with a significantly higher weight gain. Multiple regression analyses showed that increased education (inversely, β = -1.15; 95%CI -2.13, -0.17, p = 0.022), self-reported anxiety/depression (β = 1.61; 0.53, 2.69, p = 0.004), and not consuming healthy foods (β = 1.48; 0.19, 2.77, p = 0.026) were significantly associated with increased weight gain. The estimated direct effect of self-reported anxiety/depression on weight was 2.07 kg (1.07, 3.07, p < 0.001). Individuals with obesity significantly gained weight 1 month after the beginning of the quarantine. The adverse mental burden linked to the COVID-19 pandemic was greatly associated with increased weight gain.

Lifestyle modification remains a key component of cardiovascular disease prevention before and concurrently with pharmacologic interventions. The aim of this study was to assess the extent to which initiation of antihypertensive or lipid-lowering (statin) therapy predicts changes in lifestyle factors in Finnish adults. The study is a large cohort study. Participants (84% = females) were drawn from the Finnish Public-Sector study cohort of employees of 10 towns and 6 hospital districts. Results show that: - initiators experienced greater increases in body mass index and were more likely to become obese than did non-initiators. - the likelihood of becoming physically inactive was higher among initiators. - smokers who initiated preventive medication were more likely to either quit or decrease smoking compared with untreated smokers. - although average alcohol consumption decreased more among initiators than non-initiators, there was no difference in the odds of heavy drinking. Authors conclude that more effective measures are needed to support the recommended lifestyle change in relation to the initiation of pharmacologic interventions for primary prevention.
Abstract
Background Lifestyle modification is a key component of cardiovascular disease prevention before and concurrently with pharmacologic interventions. We evaluated whether lifestyle factors change in relation to the initiation of antihypertensive or lipid-lowering medication (statins). Methods and Results The study population comprised 41 225 participants of the FPS (Finnish Public Sector) study aged ≥40 years who were free of cardiovascular disease at baseline and responded to ≥2 consecutive surveys administered in 4-year intervals in 2000-2013. Medication use was ascertained through pharmacy-claims data. Using a series of pre-post data sets, we compared changes in body mass index, physical activity, alcohol consumption, and smoking between 8837 initiators and 46 021 noninitiators of antihypertensive medications or statins. In participants who initiated medication use, body mass index increased more (difference in change 0.19; 95% CI, 0.16-0.22) and physical activity declined (-0.09 metabolic equivalent of task hour/day; 95% CI, -0.16 to -0.02) compared with noninitiators. The likelihood of becoming obese (odds ratio: 1.82; 95% CI, 1.63-2.03) and physically inactive (odds ratio: 1.08; 95% CI, 1.01-1.17) was higher in initiators. However, medication initiation was associated with greater decline in average alcohol consumption (-1.85 g/week; 95% CI, -3.67 to -0.14) and higher odds of quitting smoking (odds ratio for current smoking in the second survey: 0.74; 95% CI, 0.64-0.85). Conclusions These findings suggest that initiation of antihypertensive and statin medication is associated with lifestyle changes, some favorable and others unfavorable. Weight management and physical activity should be encouraged in individuals prescribed these medications.

Type 2 diabetes is characterized by metabolic dysregulation resulting in an increased risk of cardiovascular disease The objectives of this study were: a. to determine whether weight change over 2 years was associated with subsequent cardiovascular outcomes and death in adults with diabetes, and b. to examine whether this association was modified by baseline body mass index (BMI), age, or type of glucose-lowering medications. This study is a large prospective study of adults with type 2 diabetes. One arm tested the effects of intensive glucose lowering versus standard glucose control. Whereas the second arm tested the effects of blood pressure-lowering medication versus a placebo. Results showed that that >10% weight loss was associated with >2 times higher risk of cardiovascular and all-cause mortality and was associated with 75% greater risk of major macrovascular events, compared with adults with stable weight. These associations were not significantly modified by metformin use, age, or baseline BMI. Authors conclude that unless patients specifically report lifestyle changes to lose weight, even modest weight loss may be a marker of declining health for which further clinical investigation is merited.
Abstract
CONTEXT Weight loss is strongly recommended for overweight and obese adults with type 2 diabetes. Unintentional weight loss is associated with increased risk of all-cause mortality, but few studies have examined its association with cardiovascular outcomes in patients with diabetes. OBJECTIVE To evaluate 2-year weight change and subsequent risk of cardiovascular events and mortality in established type 2 diabetes. DESIGN AND SETTING The Action in Diabetes and Vascular Disease: Preterax and Diamicron-MR Controlled Evaluation was an international, multisite 2×2 factorial trial of intensive glucose control and blood pressure control. We examined 5 categories of 2-year weight change: >10% loss, 4% to 10% loss, stable (±<4%), 4% to 10% gain, and >10% gain. We used Cox regression with follow-up time starting at 2 years, adjusting for intervention arm, demographics, cardiovascular risk factors, and diabetes medication use from the 2-year visit. RESULTS Among 10 081 participants with valid weight measurements, average age was 66 years. By the 2-year examination, 4.3% had >10% weight loss, 18.4% had 4% to 10% weight loss, and 5.3% had >10% weight gain. Over the following 3 years of the trial, >10% weight loss was strongly associated with major macrovascular events (hazard ratio [HR], 1.75; 95% confidence interval [CI], 1.26-2.44), cardiovascular mortality (HR, 2.76; 95% CI, 1.87-4.09), all-cause mortality (HR, 2.79; 95% CI, 2.10-3.71), but not major microvascular events (HR, 0.91; 95% CI, 0.61-1.36), compared with stable weight. There was no evidence of effect modification by baseline body mass index, age, or type of diabetes medication. CONCLUSIONS In the absence of substantial lifestyle changes, weight loss may be a warning sign of poor health meriting further workup in patients with type 2 diabetes.

Obesity is associated with many health issues, including thyroid problems. The aim of this observational study was to investigate the effect of weight loss surgery on thyroid hormones. 129 morbidly obese people with normal thyroid function were included in the study. 12 months after weight loss surgery, the levels of thyroid stimulating hormone (TSH) had significantly decreased from 3.3 to 2.1 µU/mL. Levels of the thyroid hormone free thyroxine (T4) also significantly decreased from 1.47 to 1.12 ng/dL. Those that lost more weight following surgery tended to have a greater reduction in TSH. Fasting blood glucose also significantly improved after surgery. The authors concluded that obesity is associated with raised TSH levels, and this makes diagnosing thyroid problems in people with morbid obesity more complicated.
Abstract
Obesity is associated with several endocrine abnormalities, including thyroid dysfunction. The objective of this study was to investigate the effect of weight loss after bariatric surgery on thyroid-stimulating hormone (TSH) levels in euthyroid patients with morbid obesity. We performed an observational study, evaluating patients with morbid obesity submitted to bariatric surgery. We included 129 patients (92 women) and 31 controls (21 women). Clinical, anthropometric, biochemical, and hormonal parameters were evaluated. The primary endpoint was circulating TSH (µU/mL). Fasting TSH levels were higher in the obese group (3.3 ± 0.2) than in the control group (2.1 ± 0.2). The mean excessive body mass index (BMI) loss (EBMIL) 12 months after bariatric surgery was 72.7 ± 2.1%. TSH levels significantly decreased in the obese patients after surgery; 3.3 ± 0.2 vs. 2.1 ± 0.2 before and 12 months after surgery, respectively. Free thyroxine (T4) (ng/dL) levels significantly decreased in the obese patients after surgery; 1.47 ± 0.02 vs. 1.12 ± 0.02 before and 12 months after surgery, respectively. TSH decreased significantly over time, and the decrement was associated with the EBMIL. In euthyroid patients with morbid obesity, weight loss induced by bariatric surgery promotes a significant decline of the increased TSH levels. This decrement of TSH is progressive over time after surgery and significantly associated with excess BMI loss.

Musculoskeletal pain is highly prevalent in old age and can be disabling to sufferers, resulting in significant economic burden and a detrimental impact on quality of life. The aim of the study was to investigate the association between self-reported sleep duration and musculoskeletal pain in Korean adult population. The study showed that extreme sleep duration is prevalent in musculoskeletal pain subjects and it is more prevalent in subjects with multi-site joint pain. Thus, both longer and shorter sleep durations were linked with a higher prevalence of musculoskeletal pain. Authors conclude that specific assessment and treatment of sleep disturbance should be included as an important part of pain management in patients with musculoskeletal pain.
Abstract
Both extremely long and short sleep durations have been associated with increased risk of numerous health problems. This study examined the association between self-reported sleep duration and reporting of musculoskeletal pain in the adult Korean population.This study included data from 17,108 adults aged ≥50 years, obtained from the Korea National Health and Nutrition Examination Survey 2010-2012 and 2013-2015. Self-reported daily hours slept and the presence of musculoskeletal pain in knee joint, hip joint, or low back were examined. Patients were stratified into 5 groups by their sleep duration: ≤5, 6, 7, 8, or ≥9 h. Multivariate logistic regression analysis was performed, adjusting for covariates including age, sex, marital status, smoking, alcohol use, family income level, education, physical exercise, body mass index (BMI), and stress level.A U-shaped relationship was observed between the length of sleep duration and the presence of musculoskeletal pain. After adjusting for covariates, sleep duration of ≤5 h or ≥9 h was significantly associated with musculoskeletal pain experienced for more than 30 days over a 3-month period. We also found that the presence of multi-site musculoskeletal pain was significantly higher among those who slept for ≤5 h or ≥9 h than in those who slept for 7 h.These findings suggest that either short or long sleep duration is associated with musculoskeletal pain among Korean adults.

Literature indicates that sedentary behaviours are linked to adverse health outcomes. The aim of the study was to investigate the relationship between screen time, including personal computer and mobile phone use, and nutrient intake among children and adolescents. The study used cross-sectional data from the Shika study which recruited Japanese children aged between 6 to 15 years of age. Results indicate a relationship between longer television viewing times and less protein, minerals, vitamins, and total dietary fibre intake. A relationship was also found between personal computer use in boys and less minerals and vitamins intake. Authors conclude that children and adolescents need to reduce the amount of time they spend watching television as well as the frequency of eating in front of the television screen in order to reduce health risk.
Abstract
BACKGROUND Sedentary behaviors have recently become an important public health issue. We aimed to investigate the relationship between screen time and nutrient intake in children and adolescents. METHODS The present study was conducted in 2013. Data were collected from children and adolescents aged between 6 and 15 years old in Shika town. Questionnaires were distributed to 1459 subjects, 1414 of whom participated in the study (96.9%). Sedentary behaviors were assessed based on participants' screen behaviors (television (TV) viewing, personal computer (PC) use, and mobile phone (MP) use). The main outcomes were the intake of nutrients from a validated food frequency questionnaire. Analysis of covariance (ANCOVA) was used to examine the significance of differences in nutrient intake estimates. Multivariate linear regression analyses, adjusting for age, BMI, and physical activity, were used to provide parameter estimates (β) and 95% CI for the relationship between screen time and nutrient intake. RESULTS In boys, longer TV viewing times correlated or tended to correlate with a lower intake of protein, potassium, calcium, iron, vitamin K, vitamin B-2, and total dietary fiber. In girls, longer TV viewing times correlated with a lower intake of protein, sodium, calcium, vitamin D, and vitamin B-2. Longer TV viewing times correlated with a higher intake of n-6 fatty acids in girls. PC use was related or tended to be related to a lower intake of potassium, iron, vitamin K, and folic acid in boys, but not in girls. A relationship was observed between MP use and a lower intake of vitamin K in boys, and MP use and a higher intake of vitamin D in girls. CONCLUSIONS The present results revealed that longer TV viewing times are associated with less protein, minerals, vitamins, and total dietary fiber intake in children and adolescents. It was also revealed that boys with PC use have less minerals and vitamins. These results support the need to design intervention programs that focus on decreasing TV viewing time in both sexes and PC use in boys while encouraging adherence to dietary guidelines among children and adolescents.

Bariatric surgery has become the most efficient way to obtain satisfying results in terms of weight loss, comorbidity improvement and survival amongst people with morbid obesity. The aim of the study is to assess the progression of type 2 diabetes and psychopathological variables before and after bariatric surgery. A secondary aim is to analyse the importance of the different variables in weight loss outcomes. The retrospective observational and cross-sectional study involves clinical data of 75 patients, aged between 23 and 64, before and after bariatric surgery. Results indicate that type 2 diabetes improved through bariatric surgery, and that type 2 diabetes, depression and eating disorders have an influence on weight loss postoperatively. Authors conclude that it is important to provide continuous psychiatric follow-up of patients who undergo bariatric surgery.
Abstract
INTRODUCTION Obesity is associated with a great number of complications, including type 2 diabetes mellitus and psychiatric pathology. Bariatric surgery is the best solution to weight loss and improvement of complications in morbid obese patients. This study aims to analyze the evolution of type 2 diabetes mellitus and psychopathologic variables before and after bariatric surgery and assess the importance of different variables in weight loss. MATERIAL AND METHODS This is a longitudinal study, which evaluates 75 patients before and after bariatric surgery (47 - LAGB - laparoscopic adjustable gastric band; 19 - RYGB - Roux-en-Y gastric bypass; 9 - sleeve) with a follow-up time between 18 and 46 months. A clinical interview and self report questionnaires were applied - Eating Disorder Examination questionnaire - EDE-Q and Beck Depression Inventory - BDI. RESULTS Results show an improvement in type 2 diabetes mellitus after surgery (X2 (1) = 26.132, p < 0.001). There was not a significant improvement among psychiatric pathology when we controlled the analysis for the type of surgery. It was verified that type 2 diabetes mellitus, depression and eating disorders in post-operative period are associated with less weight loss. This model explains 27% of weight variance after surgery (R2 = 0.265) and it is significant F (3.33) = 2.981, p = 0.038. DISCUSSION Type 2 diabetes mellitus, psychiatric pathology and eating disorders after surgery influenced weight loss. It was not clear in what way this relation was verified, neither the relation that these metabolic and psychological variables may have during the postoperative period. CONCLUSION Type 2 diabetes mellitus improved after surgery. Type 2 diabetes mellitus, depression and eating disorders influenced weight loss in the postoperative period. These variables did not influence weight loss in the preoperative period. Introdução: A obesidade associa-se a um elevado número de comorbilidades, entre as quais a diabetes mellitus tipo 2 e a patologia psiquiátrica. A cirurgia bariátrica tem demonstrado ser a melhor solução para a perda de peso e a melhoria das complicações nos casos de obesidade mórbida. O objetivo deste estudo é o de analisar a evolução da diabetes mellitus tipo 2 e de variáveis psicopatológicas antes e depois da cirurgia bariátrica e verificar o seu impacto na perda de peso. Material e Métodos: É um estudo longitudinal, que avalia 75 indivíduos antes e depois de serem submetidos a cirurgia bariátrica (47 - banda gástrica; 19 - bypass Roux-en-Y gástrico; 9 - sleeve gástrico), com tempo de follow-up entre 18 e 46 meses. Os instrumentos de avaliação foram a entrevista clínica e os questionários Eating Disorder Examination questionnaire - EDE-Q e Beck Depression Inventory - BDI. Resultados: Verificou-se melhoria relativamente à variável dicotómica diabetes mellitus tipo 2 após a cirurgia (X(1) = 26,132, p < 0,001). Não ocorreu melhoria significativa em termos de patologia psiquiátrica quando a análise foi controlada para o tipo de cirurgia. Encontrámos uma associação significativa entre as variáveis em estudo no pós-cirúrgico e a perda de peso. Este modelo explica 27% da variação do peso após a cirurgia (R2 = 0,265) e é significativo F (3,33) = 2,981, p = 0,038. Discussão: A diabetes mellitus tipo 2, patologia depressiva ou do comportamento alimentar mostraram estar relacionados com a perda de peso. Não ficou esclarecido em que sentido esta relação é estabelecida, nem a relação que estas variáveis metabólicas e psicológicas possam ter entre si ao longo do período pós cirurgia bariátrica. Conclusão: A diabetes mellitus tipo 2 evoluiu favoravelmente após a cirurgia. Diabetes mellitus tipo 2, depressão e patologia alimentar no período pós-cirúrgico associaram-se a menor perda de peso. As variáveis estudadas no período pré cirúrgico não contribuíram de forma significativa para a perda de peso.

Plain language summary
Binge eating disorder is characterised by the consumption of an objectively large amount of food in a discrete period of time (i.e. 2hrs) with an accompanying loss of control over eating. This study is a follow-up study that examined weight loss over an average of 24 months post bariatric surgery (as most studies are based on a shorter duration i.e. less than 12 months) in 59 patients. Another aim of the study was whether bariatric surgery had any effects on the remission or precipitation of binge eating. Results indicate that patients with a preoperative diagnosis of binge-eating disorder lost significantly less weight 2 years after surgery than those individuals who were free from binge-eating prior surgery. However, those with a diagnosis of binge-eating disorder who received lifestyle modifications lost significantly less than those who had bariatric surgery. Authors conclude that bariatric-surgery may be a useful long-term weight loss strategy for patients with eating disorders. However, they also recommend that these patients may benefit from additional counselling and behavioural support, such as cognitive behaviour therapy.
Abstract
OBJECTIVE A previous study reported that preoperative binge-eating disorder (BED) did not attenuate weight loss at 12 months after bariatric surgery. This report extends the authors' prior study by examining weight loss at 24 months. METHODS A modified intention-to-treat population was used to compare 24-month changes in weight among 59 participants treated with bariatric surgery, determined preoperatively to be free of a current eating disorder, with changes in 33 surgically treated participants with BED. Changes were also compared with 49 individuals with obesity and BED who sought lifestyle modification for weight loss. Analyses included all available data points and were adjusted for covariates. RESULTS At month 24, surgically treated patients with BED preoperatively lost 18.6% of initial weight, compared with 23.9% for those without BED (P = 0.049). (Mean losses at month 12 had been 21.5% and 24.2%, respectively; P = 0.23.) Participants with BED who received lifestyle modification lost 5.6% at 24 months, significantly less than both groups of surgically treated patients (P < 0.001). CONCLUSIONS These results suggest that preoperative BED attenuates long-term weight loss after bariatric surgery. We recommend that patients with this condition, as well as other eating disturbances, receive adjunctive behavioral support, the timing of which remains to be determined.
