Associations between psychological evaluation outcomes, psychiatric diagnoses, and outcomes through 12 months after bariatric surgery.

BACKGROUND: There is limited evidence about how patients' initial preoperative psychological evaluation outcomes (require follow-up [RFU], no required follow-up [NFU], and place on hold [POH]) and current psychiatric diagnoses associate with postoperative outcomes. OBJECTIVES: To test the hypotheses that patients who receive a clinical decision of RFU versus NFU from their initial psychological evaluation will be (1) more likely to experience postoperative complications, readmissions, and emergency room visits and (2) experience less weight loss over 12-months. Specific diagnoses (any psychiatric diagnosis, depression, and anxiety) are also examined for their association with weight loss over 12 months. SETTING: Midwestern medical center, United States. METHODS: The sample included 322 patients (81.1% female and 64.0% White) with completed psychological evaluations between August 2019 and December 2020. Patient demographics, psychological evaluation outcomes, current diagnoses, and postoperative outcomes were extracted from the health record. Bivariate analyses determined associations between NFU/RFU and postoperative complications (yes, no), readmissions (yes, no), and emergency room visits (yes, no). Mixed multilevel models were conducted with dichotomous variables NFU/RFU, any psychiatric diagnoses (yes, no), depression diagnoses (yes, no), or anxiety diagnoses (yes, no) as the main fixed within-group factors with weight loss (weight or percent total weight loss) used as the repeated measures. Insurance and surgical procedure were included as covariates. RESULTS: There were no significant differences in postoperative complications, readmissions, and emergency room visits between NFU and RFU groups. Patients who received a RFU versus an NFU had higher weights over 12 months (P = .001). CONCLUSION: Hypothesis 2 was only partially supported. Patients who received an RFU versus an NFU had higher weights over 12 months, but this association was not found for percent total weight loss or any of the psychiatric within-subjects variables (i.e., psychiatric diagnoses, depression, and anxiety).

Preoperative Psychological Evaluation Outcomes, Reasoning, and Demographic and Diagnostic Correlates.

PURPOSE: Little is known about associations between preoperative psychiatric, disordered eating, and substance use diagnoses with the clinical decision to require follow-up after the preoperative psychological evaluation. To determine the proportion of patients who require follow-up (no required follow-up (NFU), required follow-up (RFU), placed on hold (POH)) from the preoperative psychological evaluation, associations with diagnoses, and noted reasons for follow-up. MATERIALS AND METHODS: The sample included 508 patients (77.6% female; 64.4% White) pursuing bariatric metabolic surgery with completed psychological evaluations between August 2019 and December 2020 at a Midwest medical center. Patient demographics, psychological evaluation outcome and corresponding reasoning, and psychiatric, disordered eating, and substance use diagnoses were extracted from the health record. Descriptive and bivariate analyses determined associations between demographics and diagnoses with psychological evaluation outcomes and corresponding reasoning. RESULTS: The breakdown of psychological evaluation outcomes was 60.6% (n = 308) NFU, 38.4% (n = 195) RFU, and 1.0% (n = 5) POH. Demographic correlates of RFU included higher BMI, being single, lower educational attainment, unemployment, public/no insurance, and receiving multiple or any psychiatric diagnosis (all p-values < 0.05). Diagnostic correlates of RFU included anxiety, depression, not having a current trauma or stressor-related disorder, disordered eating, and substance use diagnoses (all p-values < 0.001). RFU/POH was primarily due to psychiatric (61%) reasons. CONCLUSION: Higher rates of RFU were observed for patients with higher economic need and with psychiatric, disordered eating, or substance use diagnoses. Future work should establish preoperative programming to assist patients with addressing ongoing psychiatric concerns prior to bariatric metabolic surgery.

Ex situ Normothermic Split Liver Machine Perfusion: Protocol for Robust Comparative Controls in Liver Function Assessment Suitable for Evaluation of Novel Therapeutic Interventions in the Pre-clinical Setting.

Background: Ex situ donor liver machine perfusion is a promising tool to assess organ viability prior to transplantation and platform to investigate novel therapeutic interventions. However, the wide variability in donor and graft characteristics between individual donor livers limits the comparability of results. We investigated the hypothesis that the development of a split liver ex situ machine perfusion protocol provides the ideal comparative controls in the investigation of machine perfusion techniques and therapeutic interventions, thus leading to more comparable results. Methods: Four discarded human donor livers were surgically split following identification and separation of right and left inflow and outflow vessels. Each lobe, on separate perfusion machines, was subjected to normothermic perfusion using an artificial hemoglobin-based oxygen carrier solution for 6 h. Metabolic parameters as well as hepatic artery and portal vein perfusion parameters monitored. Results: Trends in hepatic artery and portal vein flows showed a general increase in both lobes throughout each perfusion experiment, even when normalized for tissue weight. Progressive decreases in perfusate lactate and glucose levels exhibited comparable trends in between lobes. Conclusion: Our results demonstrate comparability between right and left lobes when simultaneously subjected to normothermic machine perfusion. In the pre-clinical setting, this model provides the ideal comparative controls in the investigation of therapeutic interventions.

The Effect of Family Member Attendance at Bariatric Surgery Appointments on Patient and Family Weight-Related Outcomes.

PURPOSE: To assess the effect of family member attendance at routine pre- and postoperative appointments on early postoperative patients' weight loss and physical activity levels and family members' weight control practices. MATERIALS AND METHODS: As part of a RCT, patients were randomized to (1) invite a romantic partner or cohabitating family member to attend routine appointments (FA arm) or (2) proceed with treatment as usual (TAU arm). Patients in FA arm were asked to invite their family member to attend four routine appointments (T1 = pre-surgery class, T2 = 1 month pre-surgery, T3 = 2 weeks post-surgery, T4 = 2 months post-surgery). Assessments of patients' percent excess weight loss (%EWL), change in body mass index (ΔBMI), and levels of physical activity and family members' weight control practices (dietary control, self-monitoring, physical activity, and psychological coping) were conducted at T1-T4 with all dyads, and attendance was documented. Of the 213 dyads approached, 63 dyads consented to participate. RESULTS: There were no significant differences in patient outcomes between FA and TAU arms or based on consistent attendance of family members. There were no significant differences in weight control practices between FA and TAU dyads. At T3 and T4, family members with consistent attendance reported higher self-monitoring, physical activity, and psychological control practices. Family members with consistent attendance reported significant increases in physical activity and psychological control practices from T1 to T4. CONCLUSIONS: Family member attendance at routine appointments had greater positive effects on family members rather than on patient outcomes.

The Delivery of Multipotent Adult Progenitor Cells to Extended Criteria Human Donor Livers Using Normothermic Machine Perfusion.

Background: Pre-clinical research with multi-potent adult progenitor cells (MAPC® cells, Multistem, Athersys Inc., Cleveland, Ohio) suggests their potential as an anti-inflammatory and immunomodulatory therapy in organ transplantation. Normothermic machine perfusion of the liver (NMP-L) has been proposed as a way of introducing therapeutic agents into the donor organ. Delivery of cellular therapy to human donor livers using this technique has not yet been described in the literature. The primary objectives of this study were to develop a technique for delivering cellular therapy to human donor livers using NMP-L and demonstrate engraftment. Methods: Six discarded human livers were perfused for 6 h at 37°C using the Liver Assist (Organ Assist, Groningen). 50 × 106 CMPTX-labeled MAPC cells were infused directly into the right lobe via the hepatic artery (HA, n = 3) or portal vein (PV, n = 3) over 20 min at different time points during the perfusion. Perfusion parameters were recorded and central and peripheral biopsies were taken at multiple time-points from both lobes and subjected to standard histological stains and confocal microscopy. Perfusate was analyzed using a 35-plex multiplex assay and proteomic analysis. Results: There was no detrimental effect on perfusion flow parameters on infusion of MAPC cells by either route. Three out of six livers met established criteria for organ viability. Confocal microscopy demonstrated engraftment of MAPC cells across vascular endothelium when perfused via the artery. 35-plex multiplex analysis of perfusate yielded 13 positive targets, 9 of which appeared to be related to the infusion of MAPC cells (including Interleukin's 1b, 4, 5, 6, 8, 10, MCP-1, GM-CSF, SDF-1a). Proteomic analysis revealed 295 unique proteins in the perfusate from time-points following the infusion of cellular therapy, many of which have strong links to MAPC cells and mesenchymal stem cells in the literature. Functional enrichment analysis demonstrated their immunomodulatory potential. Conclusion: We have demonstrated that cells can be delivered directly to the target organ, prior to host immune cell population exposure and without compromising the perfusion. Transendothelial migration occurs following arterial infusion. MAPC cells appear to secrete a host of soluble factors that would have anti-inflammatory and immunomodulatory benefits in a human model of liver transplantation.

The impact on the bioenergetic status and oxidative-mediated tissue injury of a combined protocol of hypothermic and normothermic machine perfusion using an acellular haemoglobin-based oxygen carrier: The cold-to-warm machine perfusion of the liver.

INTRODUCTION: The combination of hypothermic and normothermic machine perfusion (HMP+NMP) of the liver provides individual benefits of both techniques, improving the rescue of marginal organs. The aim of this study was to investigate the effect on the bioenergetic status and the oxidative-mediated tissue injury of an uninterrupted combined protocol of HMP+NMP using a single haemoglobin-based oxygen carrier (HBOC)-based perfusate. METHODS: Ten discarded human donor livers had either 2 hours of dual hypothermic oxygenated perfusion (D-HOPE) with sequential controlled rewarming (COR) and then NMP using the HBOC-based perfusate uninterruptedly (cold-to-warm group); or 2 hours of hypothermic oxygenated perfusion (HOPE) with an oxygen carrier-free perfusate, followed by perfusate exchange and then NMP with an HBOC-based perfusate. Markers of liver function, tissue adenosine triphosphate (ATP) levels and tissue injury were systematically assessed. RESULTS: The hypothermic phase downregulated mitochondrial respiration and increased ATP levels in both groups. The cold-to-warm group presented higher arterial vascular resistance during rewarming/NMP (p = 0.03) with a trend of lower arterial flow (p = 0.09). At the end of NMP tissue expression of markers of reactive oxygen species production, oxidative injury and inflammation were comparable between the groups. CONCLUSION: The uninterrupted combined protocol of HMP+NMP using an HBOC-based perfusate-cold-to-warm MP-mitigated the oxidative-mediated tissue injury and enhanced hepatic energy stores, similarly to an interrupted combined protocol; however, it simplified the logistics of this combination and may favour its clinical applicability.

Rationale and design of a feasibility and acceptability RCT of romantic partner and support figure attendance during bariatric surgery visits.

As US obesity rates increase, more patients, particularly females, are seeking out bariatric surgery. As bariatric surgery patients' social supports have been vastly understudied, clinicians and researchers have limited information about how to include support figures, including romantic partners, in the surgery process. To address this gap in knowledge, we are conducting a four-arm randomized controlled trial to assess the feasibility, acceptability and preliminary efficacy for the inclusion of romantic partners and support figures throughout the bariatric surgery process for a group of 110 women age 18 years or older. Patients will be randomized based upon their cohabitating romantic relationships at baseline. Female patients who have a cohabitating romantic partner will be randomized to one of two arms: partner attended (PA), and partner attended treatment as usual (PA-TU). To provide greater detail about social support during the bariatric process, interested patients (female or male) not in cohabitating romantic relationships will be randomized into support figure attended (SFA) and SFA-TU arms. Four data collection points are planned, including 4-months pre-surgery, 2 weeks pre-surgery, 2 weeks and 2-months post-surgery. Feasibility and acceptability of support figure/partner attendance collected at the final data point. Patients and support figures/partners will complete weight status, health behaviors, support for behavior change and relationship quality assessments at each time point. The rationale, design, theoretical framework, and methodology for the study are described. The results of this study will identify how support figures/partners influence patients' health behavior change and weight loss, and how relationships change over the surgery process.

Manipulation of Lipid Metabolism During Normothermic Machine Perfusion: Effect of Defatting Therapies on Donor Liver Functional Recovery.

Strategies to increase the use of steatotic donor livers are required to tackle the mortality on the transplant waiting list. We aimed to test the efficacy of pharmacological enhancement of the lipid metabolism of human livers during ex situ normothermic machine perfusion to promote defatting and improve the functional recovery of the organs. Because of steatosis, 10 livers were discarded and were allocated either to a defatting group that had the perfusate supplemented with a combination of drugs to enhance lipid metabolism or to a control group that received perfusion fluid with vehicle only. Steatosis was assessed using tissue homogenate and histological analyses. Markers for lipid oxidation and solubilization, oxidative injury, inflammation, and biliary function were evaluated by enzyme-linked immunosorbent assay, immunohistochemistry, and in-gel protein detection. Treatment reduced tissue triglycerides by 38% and macrovesicular steatosis by 40% over 6 hours. This effect was driven by increased solubility of the triglycerides (P = 0.04), and mitochondrial oxidation as assessed by increased ketogenesis (P = 0.008) and adenosine triphosphate synthesis (P = 0.01) were associated with increased levels of the enzymes acyl-coenzyme A oxidase 1, carnitine palmitoyltransferase 1A, and acetyl-coenzyme A synthetase. Concomitantly, defatted livers exhibited enhanced metabolic functional parameters such as urea production (P = 0.03), lower vascular resistance, lower release of alanine aminotransferase (P = 0.049), and higher bile production (P = 0.008) with a higher bile pH (P = 0.03). The treatment down-regulated the expression of markers for oxidative injury as well as activation of immune cells (CD14; CD11b) and reduced the release of inflammatory cytokines in the perfusate (tumor necrosis factor α; interleukin 1ß). In conclusion, pharmacological enhancement of intracellular lipid metabolism during normothermic machine perfusion decreased the lipid content of human livers within 6 hours. It also improved the intracellular metabolic support to the organs, leading to successful functional recovery and decreased expression of markers of reperfusion injury.

Development of Clinical Criteria for Functional Assessment to Predict Primary Nonfunction of High-Risk Livers Using Normothermic Machine Perfusion.

Increased use of high-risk allografts is critical to meet the demand for liver transplantation. We aimed to identify criteria predicting viability of organs, currently declined for clinical transplantation, using functional assessment during normothermic machine perfusion (NMP). Twelve discarded human livers were subjected to NMP following static cold storage. Livers were perfused with a packed red cell-based fluid at 37°C for 6 hours. Multilevel statistical models for repeated measures were employed to investigate the trend of perfusate blood gas profiles and vascular flow characteristics over time and the effect of lactate-clearing (LC) and non-lactate-clearing (non-LC) ability of the livers. The relationship of lactate clearance capability with bile production and histological and molecular findings were also examined. After 2 hours of perfusion, median lactate concentrations were 3.0 and 14.6 mmol/L in the LC and non-LC groups, respectively. LC livers produced more bile and maintained a stable perfusate pH and vascular flow >150 and 500 mL/minute through the hepatic artery and portal vein, respectively. Histology revealed discrepancies between subjectively discarded livers compared with objective findings. There were minimal morphological changes in the LC group, whereas non-LC livers often showed hepatocellular injury and reduced glycogen deposition. Adenosine triphosphate levels in the LC group increased compared with the non-LC livers. We propose composite viability criteria consisting of lactate clearance, pH maintenance, bile production, vascular flow patterns, and liver macroscopic appearance. These have been tested successfully in clinical transplantation. In conclusion, NMP allows an objective assessment of liver function that may reduce the risk and permit use of currently unused high-risk livers.

Combined Hypothermic and Normothermic Machine Perfusion Improves Functional Recovery of Extended Criteria Donor Livers.

Hypothermic oxygenated perfusion (HOPE) and normothermic perfusion are seen as distinct techniques of ex situ machine perfusion of the liver. We aimed to demonstrate the feasibility of combining both techniques and whether it would improve functional parameters of donor livers into transplant standards. Ten discarded human donor livers had either 6 hours of normothermic perfusion (n = 5) or 2 hours of HOPE followed by 4 hours of normothermic perfusion (n = 5). Liver function was assessed according to our viability criteria; markers of tissue injury and hepatic metabolic activity were compared between groups. Donor characteristics were comparable. During the hypothermic perfusion phase, livers down-regulated mitochondrial respiration (oxygen uptake, P = 0.04; partial pressure of carbon dioxide perfusate, P = 0.04) and increased adenosine triphosphate levels 1.8-fold. Following normothermic perfusion, those organs achieved lower tissue expression of markers of oxidative injury (4-hydroxynonenal, P = 0.008; CD14 expression, P = 0.008) and inflammation (CD11b, P = 0.02; vascular cell adhesion molecule 1, P = 0.05) compared with livers that had normothermic perfusion alone. All livers in the combined group achieved viability criteria, whereas 40% (2/5) in the normothermic group failed (P = 0.22). In conclusion, this study suggests that a combined protocol of hypothermic oxygenated and normothermic perfusions might attenuate oxidative stress, tissue inflammation, and improve metabolic recovery of the highest-risk donor livers compared with normothermic perfusion alone.

An effective protocol for pharmacological defatting of primary human hepatocytes which is non-toxic to cholangiocytes or intrahepatic endothelial cells.

INTRODUCTION: Pharmacological defatting of rat hepatocytes and hepatoma cell lines suggests that the same method could be used to ameliorate macrovesicular steatosis in moderate to severely fatty livers. However there is no data assessing the effects of those drugs on primary human liver cells. We aimed to determine the effectiveness of a pharmacological cocktail in reducing the in vitro lipid content of primary human hepatocytes (PHH). In addition we sought to determine the cytotoxicity of the cocktail towards non-parenchymal liver cells. METHODS: Steatosis was induced in PHH by supplementation with a combination of saturated and unsaturated free fatty acids. This was followed by addition of a defatting drug cocktail for up to 48 hours. The same experimental method was used with human intra-hepatic endothelial cells (HIEC) and human cholangiocytes. MTT assay was used to assess cell viability, triglyceride quantification and oil red O staining were used to determine intracellular lipids content whilst ketone bodies were measured in the supernatants following experimentation. RESULTS: Incubation of fat loaded PHH with the drugs over 48 hours reduced the intracellular lipid area by 54%, from 12.85% to 5.99% (p = 0.002) (percentage of total oil red O area), and intracellular triglyceride by 35%, from 28.24 to 18.30 nmol/million of cells (p<0.001). Total supernatant ketone bodies increased 1.4-fold over 48 hours in the defatted PHH compared with vehicle controls (p = 0.002). Moreover incubation with the drugs for 48 hours increased the viability of PHH by 11%, cholangiocytes by 25% whilst having no cytotoxic effects on HIEC. CONCLUSION: These data demonstrate that pharmacological intervention can significantly decrease intracellular lipid content of PHH, increase fatty acids ß-oxidation whilst being non-toxic to PHH, HIEC or cholangiocytes.

Bariatric Surgery Candidates' Peer and Romantic Relationships and Associations with Health Behaviors.

BACKGROUND: The aim was to assess the romantic and peer relationships of bariatric surgery candidates and associations with health behaviors. METHOD: Adults seeking bariatric surgery (N = 120) completed surveys addressing health behaviors and social relationships at information sessions. Analysis was done to compare male/female differences in peer and romantic relationships and associations with health behaviors. Previously published reference (REF) data on the Relationship Structures questionnaire was used for comparison, and to split our sample into those ≤ or > REF mean for relationship anxiety and avoidance. RESULTS: Our sample reported higher avoidance and lower anxiety in their close friendships and romantic relationships compared to the REF sample. Men in our sample had higher peer and romantic relationships avoidance compared to the REF sample and had significantly higher close friendship avoidance than women in our sample. Participants with lower anxiety in their romantic relationships (≤ REF) had higher uncontrolled eating and physical activity; those with more anxiety in their romantic relationships (> REF) had a higher BMI. CONCLUSIONS: Our findings highlight the potential influence that social relationships may have on health behaviors within the bariatric surgery population. Further investigation is warranted to explore male bariatric surgery candidates' relationships to inform understanding and intervention development.

Recent health insurance trends for US families: children gain while parents lose.

In the past decade, political and economic changes in the United States (US) have affected health insurance coverage for children and their parents. Most likely these policies have differentially affected coverage patterns for children (versus parents) and for low-income (versus high-income) families. We aimed to examine--qualitatively and quantitatively--the impact of changing health insurance coverage on US families. Primary data from interviews with Oregon families (2008-2010) were analyzed using an iterative process. Qualitative findings guided quantitative analyses of secondary data from the nationally-representative Medical Expenditure Panel Survey (MEPS) (1998-2009); we used Joinpoint Regression to assess average annual percent changes (AAPC) in health insurance trends, examining child and parent status and type of coverage stratified by income. Interviewees reported that although children gained coverage, parents lost coverage. MEPS analyses confirmed this trend; the percentage of children uninsured all year decreased from 9.6 % in 1998 to 6.1 % in 2009; AAPC = -3.1 % (95 % confidence interval [CI] from -5.1 to -1.0), while the percentage of parents uninsured all year rose from 13.6 % in 1998 to 17.1 % in 2009, AAPC = 2.7 % (95 % CI 1.8-3.7). Low-income families experienced the most significant changes in coverage. Between 1998 and 2009, as US children gained health insurance, their parents lost coverage. Children's health is adversely affected when parents are uninsured. Investigation beyond children's coverage rates is needed to understand how health insurance policies and changing health insurance coverage trends are impacting children's health.

Brief health literacy screening items predict newest vital sign scores.

BACKGROUND: Numeracy is an important but understudied component of health literacy (HL). The purpose of this study was to examine the predictive ability of established general HL and numeracy screening items in estimating Newest Vital Sign (NVS) scores. METHODS: We studied 241 adults attending primary care clinics in the midwestern United States. Demographic items, HL screening questions, and the NVS were administered to patients. To determine the accuracy of HL and numeracy screening items, area under the receiver operating characteristic (AUROC) curves were determined for each screening item, using NVS scores as the reference standard. RESULTS: Patients' mean age was 46.1 ± 16.3 years; 71.0% were female, 53.4% were African American, 7.5% had less than a high school education, and 44.4% were insured by Medicaid/Medicare. The mean NVS score was 3.7 ± 2.0, with 17.8% classified as having inadequate HL/numeracy (NVS score of 0 or 1). The HL screening item, "How confident are you filling out medical forms by yourself?" was the best predictor of both limited (AUROC, 0.83; 95% confidence interval [CI], 0.76-0.89) and limited/marginal (AUROC, 0.79; 95% CI, 0.73-0.85) NVS scores. The numeracy screening item, "In general, how easy or hard do you find it to understand medical statistics?" was the best predictor of both limited (AUROC, 0.83; 95% CI, 0.76-0.89) and limited/marginal (AUROC = 0.78; 95% CI, 0.72-0.84) NVS scores. CONCLUSION: Brief HL and numeracy screening items are useful for quickly estimating NVS scores among English-speaking primary care clinic populations.

Clinical utility of a brief screen for health literacy and numeracy among adults with diabetes mellitus.

BACKGROUND AND OBJECTIVES: Our objectives were to (1) compare Newest Vital Sign (NVS) scores and administration characteristics with the short (S) version of the Test of Functional Health Literacy in Adults (S-TOFHLA) and Spoken Knowledge in Low-Literacy Diabetes (SKILLD) tool and (2) gather information from research assistants (RAs) regarding their perceptions of patient understanding of NVS items. METHODS: Adults, age ? 18 years, with diabetes mellitus visiting a primary care clinic were recruited to participate. An RA orally administered a sociodemographic questionnaire. Patients completed, in random order, the NVS, S-TOFHLA, and SKILLD. Completion time for each tool was electronically recorded, while patients assessed tool difficulty using a 5-point Likert-type scale. RAs' comments regarding patients' understanding of individual NVS items were tallied. RESULTS: A total of 226 patients (mean age=53.8 years, 31% male, 45.1% African American, 28.8% high school graduate) participated. African Americans were significantly less likely to score ?4 on the NVS (adjusted OR=0.23, 95% CI=0.13, 0.42) as compared to Caucasians. NVS scores were highly correlated with S-TOFHLA scores, rho=0.62, and moderately correlated with SKILLD scores, rho=0.39. NVS scores were inversely correlated with completion time, rho=-0.25 and difficulty rating, rho=-0.37. CONCLUSIONS: Related to the care of patients with diabetes, the most important feature of the NVS is that it can quickly provide a clinician with valuable insight regarding their patients' ability to complete a practical skill (ie, interpreting a food label) needed to achieve tight blood glucose control.

Reducing drug self-injection errors: a randomized trial comparing a "standard" versus "plain language" version of Patient Instructions for Use.

BACKGROUND: Many American adults struggle to use and interpret medical-related instructions. Plain language materials have been shown to improve patient understanding and adherence. OBJECTIVE: The study objective was to compare the effectiveness of a "standard" Patient Instructions for Use (PIFU-standard) with a "plain language" Patient Instructions for Use (PIFU-PL) by testing user comprehension and ability to administer a biologic agent with an auto-injector ("pen"). METHODS: A trained research assistant administered sociodemographic items and the Rapid Estimate of Adult Literacy in Medicine to study participants (n = 50). Next, using a priori random assignment, participants received either PIFU-PL or PIFU-standard. Participants' knowledge of preparation (6 steps) and pre-injection (3 steps) procedures, and demonstrated correctness of self-administration (15 steps) were then evaluated. RESULTS: Participants receiving the PIFU-PL were more likely to correctly describe a greater number of both preparation (4.5 ± 1.3 versus 3.1 ± 1.5, P = 0.01) and pre-injection steps (2.4 ± 0.8 versus 1.6 ± 0.6, P = 0.01), and demonstrated more correct self-injection steps (13.1 ± 2.1 versus 10.8 ± 4.4, P = 0.05) as compared to participants receiving the PIFU-standard. CONCLUSION: Participants given "plain language" instructions had a significantly better understanding of how to prepare for and self-administer medication with a pen and were consistently more accurate in demonstrating how to self-inject.

Dissemination of a tobacco cessation program for unionized workers.

Many multilevel, contextually relevant, evidenced-based health promotion programs are not disseminated widely. The purpose of this study is to describe the adaptation of a published effective tobacco-use cessation intervention, which was implemented and evaluated in a broader population of unionized workers partnering with a health and welfare fund health benefits carrier. 68 tobacco users enrolled. Implementation and effectiveness outcomes indicated that most participants (69%) completed all counseling calls and at 16 weeks' follow-up, 30.9% reported not using tobacco. The intervention had relatively high levels of implementation, effectiveness, and acceptability, but low reach, highlighting issues arising during dissemination.

Tobacco use cessation and weight management among motor freight workers: results of the gear up for health study.

OBJECTIVES: To present the results of a study of a worksite-based intervention to promote tobacco use cessation and improve weight management among motor freight workers. METHODS: This study used a pre-test/post-test, non-randomized design to assess the effectiveness of a four-month intervention that addressed the social context of the work setting. We evaluated 7-day tobacco quit prevalence among baseline tobacco users, and successful weight management, defined as no weight gain in workers with BMI <25 at baseline and any weight loss among overweight and obese workers. RESULTS: At baseline, 40% were current tobacco users, and 88% had a BMI of 25 or greater. Of 542 workers invited to participate, 227 agreed to participate and received at least the first telephone call (42%). Ten-month post-baseline, baseline tobacco users who participated in the intervention were more likely to have quit using tobacco than non-participants: 23.8% vs. 9.1% (p = 0.02). There was no significant improvement in weight management. CONCLUSIONS: Incorporating work experiences and job conditions into messages of health behavior change resulted in significant tobacco use cessation among participating motor freight workers.

Setting the stage: Surgery patients' expectations for greetings during routine office visits.

BACKGROUND: The need for surgeons to exhibit adequate communication skills is paramount to providing exemplary patient care. The manner in which patients are greeted by their surgeon sets the stage for the remainder of the clinical encounter. This study examined patients' expectations for greetings upon meeting a surgeon for the first time. MATERIALS AND METHODS: A convenience sample of 152 English-speaking patients (> or =21 y of age) attending a university-based vascular surgery clinic were recruited to participate in this study. Eligible patients were interviewed prior to their consultation using valid and reliable questionnaires to obtain data about sociodemographic characteristics and expectations for greetings upon meeting a surgeon for the first time. RESULTS: Patients' mean age was 61.4 +/- 14.6 approximately half (n = 81;54.3%) were male, and most were Caucasian (n = 148; 97.4%). Most (n = 132; 86.8%) patients wanted the surgeon to shake their hand, 113 (74.3%) wanted their first name to be used when a surgeon greets them, and 86 (56.6%) wanted a surgeon to introduce him/herself using his/her last name. Patients also desired for surgeons to be attentive/calm and make patient feel like a priority, adjust vocabulary and/or explain better, and be friendly, personable, polite, respectful, and/or courteous. CONCLUSIONS: Surgeons should shake hands, use patients' first names, and introduce themselves using their last names when greeting patients for the first time. They should also be pleasant, personable, and make the patient feel like a priority. Additionally, surgeons should be cognizant of the way in which they present information to patients and verify understanding.
