Grandparent Coresidence and Risk of Early Child Overweight and Obesity in Low-Income,Hispanic Families in New York City

ObjectiveChildren in low-income Hispanic families are at high risk of obesity and are more likely to live with grandparents than their non-Hispanic white counterparts. We aimed to determine if grandparent coresidence (prenatal through age 2 years) was associated with: 1) obesogenic feeding practices; and 2) child weight outcomes from birth to three years.MethodsWe analyzed data from 267 low-income, Hispanic mother-infant pairs in the control group of an obesity prevention trial in New York City. Linear and logistic regression tested differences in obesogenic feeding practices and weight outcomes at 2 and 3 years, dependent upon grandparent coresidence. Multilevel modeling tested associations between grandparent coresidence and WFAz over time.ResultsPersistent grandparent coresidence (vs none) was associated with putting cereal in the bottle (adjusted odds ratio [aOR] 3.46; 95% confidence interval [CI] 1.43, 8.40). Persistent grandparent coresidence (vs none) was associated with higher mean WFAz (2 years: B 0.83; 95% CI 0.41, 1.25; 3 years: B 0.79; 95% CI 0.32, 1.25) and higher odds of child overweight/obesity risk (2 years: aOR 4.38; 95% CI 1.64, 11.69; 3 years: aOR 3.15; 95% CI 1.19, 8.36). In multilevel models, more occasions of grandparent coresidence were associated with higher WFAz.ConclusionsGrandparent coresidence may be associated with higher risk of child overweight/obesity in low-income, Hispanic families. Further research is needed to elucidate mechanisms of these associations and to inform obesity prevention strategies in the context of multigenerational families.     

Alteration of lumbar muscle morphology and composition in relation to low back pain: a systematic review and meta-analysis

BACKGROUND CONTEXTPrevious studies have proposed that there is a relationship between low back pain (LBP) and morphology and composition of paraspinal muscles. However, results have been conflicting, especially regarding fatty infiltration of muscles.PURPOSEThe primary goal of this study was to review and analyze results from imaging studies which investigated morphological and composition changes in the multifidus, erector spinae and psoas major muscles in people with LBP.STUDY DESIGN/SETTINGSystematic review with meta-analysis.PATIENT SAMPLEA patient sample was not requiredOUTCOME MEASURESThis review did not have outcome measures.METHODSPubMed, Scopus, Web of Sciences, EMBASE and ProQuest were searched for eligible studies up to 31st July 2020 (all languages). A systematic search of electronic databases was conducted to identify studies investigating the association between the morphology and fat content of lumbar muscles in people with LBP compared with a (no LBP) control group. 13,795 articles were identified. Based on the screening for inclusion/ exclusion, 25 were included. The quality of the studies was evaluated using the Newcastle-Ottawa Scale. From the 25 articles, 20 were included in the meta-analysis.RESULTSResults showed that the total cross-sectional area of the multifidus was smaller in people with LBP (Standardized mean difference, SMD = -0.24, 95% CI = -0.5 to 0.03). Combined SMDs showed a medium effect of LBP on increasing multifidus muscle fat infiltration (SMD = 0.61, 95% CI = 0.30 to 0.91). There were no LBP related differences identified in the morphology or composition of the lumbar erector spine and psoas major muscles.CONCLUSIONSPeople with LBP were found to have somewhat smaller multifidus muscles with a significant amount of intramuscular fat infiltration. Varying sample size, age and BMI of participants, quality of studies and the procedures used to measure fat infiltration are possible reasons for inconsistencies in results of previous studies.     

Effect of a Simple Exercise Program on Hospitalization-Associated Disability in Older Patients: A Randomized Controlled Trial

ObjectiveHospitalization-associated disability [HAD, ie, the loss of ability to perform ≥1 basic activities of daily living (ADLs) independently at discharge] is a frequent condition among older patients. The present study assessed whether a simple inpatient exercise program decreases HAD incidence in acutely hospitalized very old patients.DesignIn this randomized controlled trial (Activity in Geriatric Acute Care) participants were assigned to a control or intervention group and were assessed at baseline, admission, discharge, and 3 months thereafter.Setting and ParticipantsIn total, 268 patients (mean age 88 years, range 75–102) admitted to an acute care for older patients unit of a public hospital were randomized to a control (n = 125) or intervention (exercise) group (n = 143).MethodsBoth groups received usual care, and patients in the intervention group also performed simple supervised exercises (walking and rising from a chair, for a total duration of ∼20 minutes/day). We measured ADL function (Katz index) and incident HAD at discharge and after 3 months (primary outcome) and Short Physical Performance Battery, ambulatory capacity, number of falls, rehospitalization, and death during a 3-month follow-up (secondary outcomes).ResultsMedian duration of hospitalization was 7 days (interquartile range 4 days). The intervention group had a lower risk of HAD with reference to both baseline [odds ratio (OR) 0.36; 95% confidence interval (CI) 0.17–0.76, P = .007] and admission (OR 0.29; 95% CI 0.10–0.89, P = .030). A trend toward an improved ADL function at discharge vs admission was found in the intervention group compared with controls (OR 0.32; 95% CI ‒0.04 to 0.68; P = .083). No between-group differences were noted for the other endpoints (all P > .05).Conclusion and ImplicationsA simple inpatient exercise program decreases risk of HAD in acutely hospitalized, very old patients.     

Curbing the tobacco epidemic: Employing behavioral strategies or rearranging the deckchairs on the Titanic?

Henningfield brilliantly dissected the deadly comprehensive tactics of the tobacco industry but Food and Drug Administration and WHO strategies against the tobacco epidemic must be questioned. The Food and Drug Administration has the authority to regulate tobacco production (2009 Tobacco Control Act) but fails to ban menthol and reduce cigarettes nicotine content. As little has changed, the Healthy People 2010 objective of reducing the prevalence of cigarette smoking among adults to 12% by 2010 in the US will be attained by 2030. The monitoring of the WHO Framework Convention on Tobacco Control (WHO FCTC) is passive, even when governments repeatedly violate the Article 5.3 of the Convention, which specifically requires protecting public policy from tobacco industry interference. Since 2004, the year after the adoption of the Convention, the prevalence of daily smoking has leveled off and the 2012 annualized rate of change in prevalence of daily smoking was almost null. This contrasts with a 2% annual decrease in the prevalence of daily smoking from 1980 to 2004. The tobacco endgame needs acts, not bureaucracies. Two counties have been moving forward, Brazil has banned menthol and Australia has implemented plain packaging.     

Building a collaboration to improve surgical research through EORTC/ESSO 1409-CLIMB study: A prospective liver metastasis database with an integrated quality assurance program

The challenges of conducting surgical oncology trials have resulted to low quantity and poor quality research [1,2]. Considering the definitive role of surgery to offer cure, immediate response to improve surgical research is needed [3]. The European Organization for Research and Treatment of Cancer (EORTC) and the European Society of Surgical Oncology (ESSO) share the vision to achieve excellent surgical research and care for cancer patients. Building on their complimentary expertise, they embarked on a pilot project to map out challenges and initiate a sustainable collaboration to advance cancer surgery research in Europe. This pilot project is EORTC-ESSO 1409 GITCG/ ESSO-01: A Prospective Colorectal Liver Metastasis Database with an Integrated Quality Assurance Program (CLIMB). This article will describe the challenges, milestones and vision of both organizations in setting up this collaboration.     

A Bayesian Approach for Incorporating the EQ-5D Visual Analog Scale When Estimating the Health-Related Quality of Life

ObjectivesThe EuroQoL 3-level version of EQ-5D and 5-level version of EQ-5D questionnaires are often used to quantify health states. They include ordinal responses across 5 health dimensions (EQ-5D index) and an EQ-visual analog scale (EQ-VAS) overall health rating. We investigated the value of incorporating the EQ-VAS to update health utility estimates using a Bayesian framework.MethodsWe created a joint bivariate normal EQ-VAS and EQ-5D index utility model and compared this to a univariate normal EQ-5D index utility model. We tested these models for 1026 Sri Lankan patients with chronic kidney disease and 94 Australian patients with wounds. We validated our approach by simulating EQ-VAS and EQ-5D index responses and applying our Bayesian model and then comparing the modeled estimates to our observed data.ResultsThe combined model showed a reduction in estimate uncertainty for all respondents. Compared with the EQ-5D index-only model, the mean utility for Sri Lankan respondents dropped from 0.556 (0.534-0.579) to 0.540 (0.521-0.559) in men and increased from 0.489 (0.461-0.518) to 0.528 (0.506-0.550) in women, with reduced credible interval width by 13% and 23%, respectively. The mean utility in Australian respondents moved from 0.715 (0.633-0.800) to 0.716 (0.652-0.782) in men, and 0.652 (0.581-0.723) to 0.652 (0.593-0.711) in women, with reduced credible interval width by 23% and 17%, respectively. The credible interval width for simulated data also narrowed, ranging from 8.3 to 8.5%.ConclusionsIncluding the EQ-VAS through Bayesian methods can add value by reducing requisite sample sizes and decision uncertainty using small amounts of additional data that is often collected but rarely used.
