RESUMO

Systemic and social factors, like poverty and food insecurity, negatively influence fruit and vegetable (FV) intake and body mass index (BMI) among Latino/a children. Behavioral programs are needed to support children's nutrition. This study examined program effects on FV intake and BMI outcomes for Mexican-heritage children (9-11 years). The program used a modified stepped-wedge design in the Lower Rio Grande Valley of Texas (2019 and 2020). Promotoras led experiential nutrition education sessions and collected height, weight, and instant skin carotenoid scores (biomarker for FV intake) at pre-test (baseline), post-test (6 weeks), and maintenance (3-4 months after post-test). Mean changes and group differences in skin carotenoid scores, BMI z-scores and percentiles were obtained from analyses of variance. Linear mixed-effects models were used to determine overall program effects. Mexican-heritage children were enrolled (n = 57 and 52.6% female). An overall decrease in skin carotenoid scores was observed at post-test (-15.1; 95% CI: -24.95, -5.33). While scores varied widely (range: 17-498), an increase of 14.8 ± 23.8 points occurred in one intervention group. Compared to the control period, greater reductions in BMI outcomes occurred during the program. These findings provide evidence for the use of strengths-based approaches in behavioral nutrition programs.

RESUMO

AIMS: We hypothesized that glycemic control in outpatients, measured by HbA1c, was worse during the early months of the COVID-19 pandemic than in 2019. We sought to quantify how much worse and to determine if social determinants of health were associated with these differences. MATERIALS AND METHODS: Data were extracted from the electronic medical records of 2 cohorts of patients seen in the family medicine clinic of a southeastern academic health center. Three hundred patients with baseline HbA1c results as well as HbA1c results in May 2019 or May 2020 were evaluated. RESULTS: The groups had similar mean baseline HbA1c (7.65, SD = 1.50 for 2019; 7.61, SD = 1.71 for 2020; P = .85). Mean May HbA1c decreased from baseline in 2019 (7.19, SD = 1.45) but rose in 2020 (7.63, SD = 1.73), a statistically significant difference (P < .01). Controlling for age, gender, race, and insurance status, HbA1c in May 2020 (meanadj = 7.73) was significantly higher than in May 2019 (meanadj = 7.16). CONCLUSIONS: During the early months of the COVID-19 pandemic, glycemic control in our patient population was significantly worse than during the same period in 2019 (mean HbA1c difference = 0.57). Contrary to our expectations, we did not find associations between patient demographic variables and glycemic control, including race.

RESUMO

Using data from Truven Health MarketScan Commercial Claims and Encounters Database between 2009 and 2015, we studied the effects of medical and recreational marijuana laws on opioid prescribing in employer-sponsored health insurance. We used a differences-in-differences (DD) approach and found that the implementation of medical marijuana laws (MMLs) and recreational marijuana laws (RMLs) reduced morphine milligram equivalents per enrollee by 7% and 13%, respectively. The reduction associated with MMLs was predominately in people aged 55-64, whereas the reduction associated with RMLs was largely in people aged 35-44 and aged 45-54. Our findings suggest that both MMLs and RMLs have the potential to reduce opioid prescribing in the privately insured population, especially for the middle-aged population.

RESUMO

Different water quality sampling practices such as location selection or frequency can inform future watershed management strategies. The objective of this work was to compare water quality sampling strategies based on different weighted criteria to determine the optimal sampling frequency and sampling location for an urbanized, eutrophic, freshwater system. Weekly water sampling was conducted over a 2-year period at five locations for six water quality parameters. This high frequency (HF) dataset was then deconstructed into a lower frequency (LF) dataset to simulate a monthly sampling strategy. Statistical analyses conducted showed that for all sampling locations the LF datasets were not significantly different from the HF datasets, suggesting monthly sampling is sufficient to capture the overall water quality conditions in this system. A multi-criteria decision analysis was constructed for statistical and operational criteria to determine the optimal sampling locations given different criteria weights. Results showed that the optimal sampling location changed depending on the criteria weighting, suggesting that statistical analyses alone would not be sufficient to determine optimal sampling locations in this system. This analysis was then used if optimal sampling location depended on specific water quality monitoring goals. Results showed that the optimal location depends on the particular water quality monitoring goals and that this effect should also be considered in the design of future sampling programs.

RESUMO

The EU research initiative OrBiTo (oral biopharmaceutics tools) involving partners from academia, pharmaceutical industry, small medium enterprises and a regulatory agency was launched with the goal of improving tools to predict the absorption of drugs in humans and thereby accelerating the formulation development process. The OrBiTo project was divided into four work packages (WP), with WP2 focusing on characterization of drug formulations. The present work introduces the OrBiTo WP2 Decision Tree, which is designed to assist the investigator in choosing the most appropriate in vitro methods for optimizing the oral formulation design and development process. The WP2 Decision Tree consists of four stages to guide the investigator. At the first stage, the investigator is asked to choose the formulation type of interest. At the second stage, the investigator is asked to identify which type of equipment (compendial/modified/noncompendial) is preferred/available. At the third stage, characteristics of the active pharmaceutical ingredient (API) are evaluated and in the fourth stage of the decision tree, suitable experimental protocols are recommended. A link to the living Decision Tree document is provided, and we now invite the pharmaceutical sciences community to apply it to current research and development projects and offer suggestions for improvement and expansion.

RESUMO

BACKGROUND: Ovarian cancer is the leading cause of death among cancers of the female genital tract, with poor outcomes despite chemotherapy. There was a persistent socioeconomic gradient in 1-year survival in England and Wales for more than 3 decades (1971-2001). Inequalities in 5-year survival persisted for more than 20 years but have been smaller for women diagnosed around 2000. We explored one possible explanation. METHODS: We analysed data on 1406 women diagnosed with ovarian cancer during 1991-1998 and recruited to one of two randomised clinical trials. In the second International Collaborative Ovarian Neoplasm (ICON2) trial, women diagnosed between 1991 and 1996 were randomised to receive either the three-drug combination cyclophosphamide, doxorubicin and cisplatin (CAP) or single-agent carboplatin given at optimal dose. In the ICON3 trial, women diagnosed during 1995-1998 were randomised to receive either the same treatments as ICON2, or paclitaxel plus carboplatin.Relative survival at 1, 5 and 10 years was estimated for women in five categories of socioeconomic deprivation. The excess hazard of death over and above background mortality was estimated by fitting multivariable regression models with Poisson error structure and a dedicated link function in a generalised linear model framework, adjusting for the duration of follow-up and the confounding effects of age, Federation of Gynecology and Obstetrics (FIGO) stage and calendar period. RESULTS: Unlike women with ovarian cancer in the general population, no statistically significant socioeconomic gradient was seen for women with ovarian cancer treated in the two randomised controlled trials. The deprivation gap in 1-year relative survival in the general population was statistically significant at -6.7% (95% CI (-8.1, -5.3)), compared with -3.6% (95% CI (-10.4, +3.2)) in the trial population. CONCLUSIONS: Although ovarian cancer survival is significantly lower among poor women than rich women in England and Wales, there was no evidence of an association between socioeconomic deprivation and survival among women with ovarian cancer who were treated and followed up consistently in two well-conducted randomised controlled trials. We conclude that the persistent socioeconomic gradient in survival among women with ovarian cancer, at least for 1-year survival, may be due to differences in access to treatment and standards of care.

RESUMO

BACKGROUND: Fibromyalgia (FM) is an idiopathic, functional syndrome characterized by chronic, widespread pain and diffuse tenderness. This disorder affects more than 6 million patients in the United States and is associated with significant clinical and economic burdens. OBJECTIVES: The objectives of this study were to: 1) estimate the costs associated with a FM diagnosis; and 2) estimate the impact of chronic opioid use on the costs of FM patients. RESEARCH DESIGN: Case-control study. METHODS: Subjects were identified in a large nationally representative database of commercially insured patients. Propensity score-matched analyses included 445,912 FM-control pairs in the first analysis, while the second analysis included 48,333 chronic opioid users with the FM-control pairs. Primary outcomes of interest were the medical and prescription costs compared between matched pairs, based on propensity for being a case as evidenced by coefficients obtained from a first-stage logistic regression. Patient characteristics considered include: state of residence, diagnosing provider type, comorbid conditions, and concurrent medication use. RESULTS: When controlling for propensity to receive a FM diagnosis, the actual diagnosis has a small effect on medical (-$83.54 [95% CI, -152.55 to -16.53]) and prescription ($120.31 [95% CI, 109.98-130.62]) costs. However, the effect of chronic opioid use in FM patients on medical ($9094.05 [95% CI, 8924.79-9263.31]) and prescription ($3391.81 [95% CI, 3368.84-3414.79]) costs is much more substantial. CONCLUSIONS: While the differences seen in FM patients and controls are marginal, those attributed to chronic opioid use in these patients are significantly higher. Chronic opioid therapy to treat FM is a practice based not on evidence available to practitioners, but on other variables.

RESUMO

BACKGROUND AND PURPOSE: MR imaging is currently not used to evaluate CSF flow changes due to short-lasting physiological maneuvers. The purpose of this study was to evaluate the ability of MR imaging to assess the CSF flow response to a Valsalva maneuver in healthy participants. MATERIALS AND METHODS: A cardiac-gated fast cine-PC sequence with ≤15-second acquisition time was used to assess CSF flow in 8 healthy participants at the foramen magnum at rest, during, and immediately after a controlled Valsalva maneuver. CSF mean displacement volume VCSF during the cardiac cycle and CSF flow waveform App were determined. A work-in-progress real-time pencil-beam imaging method with temporal resolution ≤56 ms was used to scan 2 participants for 90 seconds during which resting, Valsalva, and post-Valsalva CSF flow, respiration, and HR were continuously recorded. Results were qualitatively compared with invasive craniospinal differential pressure measurements from the literature. RESULTS: Both methods showed 1) a decrease from baseline in VCSF and App during Valsalva and 2) an increase in VCSF and App immediately after Valsalva compared with values measured both at rest and during Valsalva. Whereas fast cine-PC produced a single CSF flow waveform that is an average over many cardiac cycles, pencil-beam imaging depicted waveforms for each heartbeat and was able to capture many dynamic features of CSF flow, including transients synchronized with the Valsalva maneuver. CONCLUSIONS: Both fast cine-PC and pencil-beam imaging demonstrated expected changes in CSF flow with Valsalva maneuver in healthy participants. The real-time capability of pencil-beam imaging may be necessary to detect Valsalva-related transient CSF flow obstruction in patients with pathologic conditions such as Chiari I malformation.

RESUMO

Lost or discarded fishing nets are a significant component of marine debris which has trans-boundary impacts in large marine ecosystems. Such 'ghost nets' cause the by-catch of marine fauna and require retrieval from coastlines where they wash up. Identifying the causes of discarded nets and feasible intervention points requires analysis of a complex value chain and the stakeholders within it, yet no studies have attempted this. In this paper we combine Value Chain Analysis, commonly applied to understand value-adding for a commodity, with elements of Life Cycle Assessment and social network analysis to examine the drivers, stakeholders, economic, environmental and social costs and benefits in the life of a trawl net. We use the Arafura Sea as a case study, which is shared by Indonesia, Papua New Guinea and Australia, and is the focus of a Trans-boundary Diagnostic Assessment (TDA) within the Arafura-Timor Seas Ecosystem Action program (ATSEA). We follow a trawl net through four sub-systems: manufacture of webbing in South Korea, fishing and loss by an Indonesian vessel, retrieval as ghost net on the northern Australian coastline by Indigenous rangers, and disposal or re-cycling as 'GhostNet Art' by Indigenous artists. Primary stakeholders along the value chain incur economic and social benefits, and economic and environmental costs. There is an anomaly in the chain between Indonesian fishermen and Indigenous rangers, artists and communities due to the lack of market linkages between these primary stakeholders. The first 'nexus of influence' where reductions in net losses and environmental costs can be achieved is through interactions between GhostNets Australia, the World Wide Fund for Nature and the Australian Government, which can influence Indonesian fishery management institutions and fishing crews. The second nexus is via the international art market which by publicising GhostNet Art can raise awareness amongst fish consumers about the impacts of ghost nets, and hence influence Indonesian fishing companies. GhostNets Australia is a key bridging organisation in the network, linking stakeholders across scales and sub-systems. Feasible preventative interventions are discussed to rectify the anomaly in the value chain. The importance of GhostNets Australia and ATSEA in the evolving adaptive co-management and trans-boundary governance of fisheries is highlighted. However, the prevention of ghost nets will result in trade-offs in benefits for the livelihoods of primary stakeholders. The utility of the method for analysing marine debris in TDAs, and ATSEA in particular, is discussed.

RESUMO

BACKGROUND: Inuvialuit of Arctic Canada are at high risk for inadequate vitamin D status as a result of rapid dietary transitions and a lack of solar ultraviolet B exposure. This may have implications for the development of adverse skeletal diseases, cardiovascular diseases and cancers. Data are limited regarding supplement use in Arctic Aboriginal populations. The present study aimed to describe the type and extent of supplement use, emphasising vitamin D, and to identify differences between supplement users and non-users. METHODS: Supplement information was collected from a population-specific quantitative food frequency questionnaire in three communities in the Northwest Territories, Canada, as part of a cross-sectional study. Data were analysed for frequency of supplementation and types of supplements. Users and non-users were compared in terms of age, sex, body mass index, education, marital status, income support, employment and chronic disease diagnosis using nonparametric tests and the chi-squared test. RESULTS: Response rates ranged from 65% to 85%. Included in the analysis were 192 Inuvialuit (45 males, 147 females) with a mean (SD) age of 43.6 (13.9) years. Twenty-three percent reported using a supplement, with multivitamins being the most common. Three percent indicated taking a vitamin D-containing supplement. No significant differences between supplement users and non-users were found. CONCLUSIONS: Despite limited sun exposure for many months of the year, a small proportion of Inuvialuit adults were using supplements, and specifically vitamin D-containing supplements. Future population-based intervention strategies should promote consumption of vitamin D rich foods and encourage the use of vitamin D supplements if diet alone is unable to meet recommendations.

RESUMO

OBJECTIVES: To characterize the variability in patient understanding and interpretation of quantitative statements from prescription orders and to evaluate the influence of sociodemographic characteristics on how patients interpret quantitative statements. METHODS: Participants were recruited in both a clinic and pharmacy setting in Kentucky. Patients were given a survey that asked for general background information and two questions pertaining to their experience with topical products. Then, patients were read a scenario and asked to use a provided tube of cream and squeeze out what they considered a small amount. RESULTS: 100 eligible patients participated in the study, with the majority having previous counseling on the use of topical products. The mean (±SD) cream weight representing a small amount was 0.36 ± 0.50 g. Regression analysis demonstrated a significant nonlinear relationship for two of the patient characteristics, age and body mass index (BMI), with the greatest effect in the middle of age and BMI distributions (at approximately age 50 years and BMI 30 kg/m²). No evidence indicated that gender, race, education, or previous experience with or education about topical products had any effect on cream weight perception. CONCLUSION: Patients demonstrated tremendous variability in the interpretation of a small amount of topical product cream. Further research should be conducted to determine whether policy changes are warranted to require more specific prescription order instructions in the outpatient setting.

RESUMO

BACKGROUND: Depression is the most common mental disease in patients hospitalized with physical illness. Disorders of anxiety and depression in general hospitals are frequently underdiagnosed and inappropriately treated. AIM: To assess the prevalence of undiagnosed anxiety and depression in surgical inpatients and assess the referral rate and utilization of liaison psychiatry services. METHODS: A prospective study of surgical admissions (n = 96) to two surgical services at two separate institutions between 01/01/05 and 31/12/05. The Hospital Anxiety and Depression (HADS) scale was used to evaluate all patients. RESULTS: About 12.5% of patients had significant depression, 18.75% had significant anxiety, and 8.3% had significant mixed anxiety and depression. About 22.9% of patients warranted referral to liaison psychiatry services for further assessment and management. CONCLUSIONS: Anxiety and depression are highly prevalent in surgical inpatients. An increased awareness of the possibility of undiagnosed psychiatric disorders is required, along with prompt and appropriate use of liaison psychiatry services.

RESUMO

Despite the many potential sources of stress and strain that accompany a migration situation, there are very few data in official statistics with regard to the health and social situation of migrants in Germany. The fact that this information is not available for public health reporting could lead to problems of improper, lacking or excessive health care. A working group within the Arbeitskreis Migration und Offentliche Gesundheit has been addressing this problem since 2003. In this article, a systematic overview of the most important data sources for public health reporting and of the indicators for migration background and social status that each one contains will be given. After that we will present examples of good practice in migration-sensitive data collection at the local and national level. Finally suggestions for improving the data situation with regard to the health of migrants based on the recommendation for recording the migration status in epidemiological studies will be made.

RESUMO

Epilepsy surgery plays an important role in the management of patients with medically refractory temporal lobe epilepsy and lesional epilepsies. When performed early in the course of the illness, surgery can render many patients seizure-free and greatly improve their quality of life. In southern Africa, as in many developing nations, thousands of patients could benefit from epilepsy surgery, but inequalities in healthcare provision mean that ready access to surgical facilities is largely restricted to those with private healthcare insurance. Over the past 5 years, more than 250 patients have had epilepsy surgery in Cape Town; the cause of epilepsy in six of these individuals was neurocysticercosis resulting from central nervous system infection by the larval stage of the pork tapeworm (Taenia solium), which is a common cause of epilepsy in the tropics. In all cases, surgery was successful, with patients becoming seizure-free and reporting a much improved quality of life.

RESUMO

There is a great need for an integrated international effort in research and training using rapid, easy to use, biomarker and microscale ecotoxicity techniques. These techniques must be directed, coordinated and formulated into protocols that contribute to the prevention and reduction of marine pollution world-wide and the improvement of ocean and human health. This need should be considered as urgent by marine environmental scientists, managers and policy makers throughout the world. Our paper discusses such techniques and suggests a four-point framework for advancing work towards their wider use, particularly in developing coastal nations.

RESUMO

In the last few years dramatic changes have occurred in the way health care is delivered and financed in the United States. Academic medical centers have been slow in helping students understand what these changes will mean. We developed a series of student-run seminars and attempted to study what effect these seminars had on the students' attitudes towards many aspects of the current health care environment. We used recent journal articles as the basis for a student-led seminar series addressing many issues in the current health care environment. A previously developed 33-item survey was administered to the students before and after the seminars to evaluate any changes that occurred in their attitudes towards the evolving health care system. The students' responses showed significant changes on eight of the items surveyed. These included a more negative feeling about non-physician health care providers, a greater appreciation of the need for physicians to become more actively involved with social issues, and a greater understanding of the financial aspects of medicine. After a student-led seminar series there were significant changes in students' attitudes regarding several aspects of the changing health care environment in the United States.

RESUMO

Social cost studies report that alcohol use and misuse impose a great economic burden on society, and over half of the total economic costs are estimated to be due to the loss of work productivity. Controversy remains, however, as to the magnitude and direction of the effects of alcohol consumption on productivity. Furthermore, most of the studies have looked at the relationship between problem drinking and wages. This paper investigates the impact of problem drinking on employment by analysing a random sample of men and women of prime working age from six Southern states in the US (Alabama, Arkansas, Georgia, Louisiana, Mississippi and Tennessee). The data set contains 4898 females and 3224 males, with information on both employment and problem drinking. To eliminate the bias that may result from single-equation estimation, we used a bivariate probit model to control for possible correlation in the unobservable factors that affect both problem drinking and employment. We find no significant negative association between problem drinking and employment for both men and women, controlling for other covariates. The findings are consistent with other research and highlight several methodological issues. Furthermore, the study suggests that estimates of the costs of problem drinking may be overstated owing to misleading labour supply relationships.

RESUMO

The effects of acute (24 h) exposure to the antidepressants amitriptyline, imipramine (both tricyclics), fluoxetine (a selective serotonin re-uptake inhibitor) and tranylcypromine (a monoamine oxidase inhibitor) on DNA damage in cultured C6 rat glioma cells were determined using an alkaline comet assay. The effects of manipulation of intracellular cyclic AMP by pretreatment with dibutyryl cyclic AMP (dBcAMP) and 3-isobutyl-1-methylxanthine (IBMX) were also studied. For fluoxetine, the effects of addition of exogenous glutathione (GSH) and pretreatment with L-buthionine sulfoximine (BSO) were also assessed. There were increases in DNA damage with increasing concentrations of antidepressants. IBMX pretreatment protected against antidepressant-induced DNA damage in C6 cells pretreated with dBcAMP. Addition of exogenous reduced GSH and BSO increased DNA damage after fluoxetine exposure. The data show that the antidepressants induce significant amounts DNA damage in C6 cells.

RESUMO

BACKGROUND: Disease due to serogroup C Neisseria meningitidis is life-threatening and potentially preventable by vaccination. In 1999, the UK instigated mass vaccination after a sustained increase in serogroup C meningococcal disease. In the same year, Victoria, Australia experienced a similar change in disease epidemiology. It is timely to undertake an economic evaluation of options for community vaccination in Australia based on local data. METHODS: Cost-effectiveness and cost-benefit analyses of three options for use of polysaccharide vaccine were undertaken for a hypothetical population aged 15--19 years. Baseline analyses assumed 5 years' duration of vaccine protection following a single year of programme implementation. Sensitivity analyses of key variables were performed, including vaccine coverage and effectiveness, case fatality rate and the discount rate. Outcomes included the number of people vaccinated, cases averted, life-years saved and disability-adjusted life-years (DALY) averted. Cost-benefit analysis used lost earnings avoided as a measure of vaccination benefit. RESULTS: Vaccination of people aged 15--19 years in a defined population with a high rate of disease was the most cost-effective option. Compared with no vaccination and assuming 5 years' duration of protection and exclusion of direct cost savings, this resulted in a discounted cost per life-year saved of $23,623, a cost per DALY avoided of $21,097 and benefits exceeding costs in discounted terms. The 'break-even' incidence rate for this option with exclusion of direct cost savings was 14.0/100,000. CONCLUSIONS: Community use of polysaccharide vaccination may be cost effective in Australia under certain conditions. Economic evidence favours use of vaccination in well-defined populations with a high rate of disease. Policy decision-making also requires consideration of non-economic factors, including feasibility of implementation and risk perception by the community.

RESUMO

A normative sample of 1,114 children was contrasted with a sample of 620 sexually abused children and 577 psychiatric outpatients on the Child Sexual Behavior Inventory (CSBI), a 38-item behavior checklist assessing sexual behavior in children 2 to 12 years old. The CSBI total score and each individual item differed significantly between the three groups after controlling for age, sex, maternal education, and family income. Sexually abused children exhibited a greater frequency of sexual behaviors than either the normative or psychiatric outpatient samples. Test-retest reliability and interitem correlation were satisfactory. Sexual behavior problems were related to other generic behavior problems. This contributed to the reduced discrimination between psychiatric outpatients and sexually abused children when compared to the normative/sexually abused discrimination.
