Surgical Treatment for Women with Breast Cancer in Relation to Socioeconomic and Insurance Status

Based on the National Breast Cancer Audit of the Royal Australasian College of Surgeons an association between patient age and type of breast cancer surgery received has already been demonstrated. The aim of this study is to assess the patterns of surgical treatment for women with early breast cancer in relation to socioeconomic and insurance status. Data on patient demographics, diagnostic, and surgical procedures and cancer characteristics in 115,872 episodes of early breast cancer reported to the National Breast Cancer Audit between 1998 and 2012 is used for this study. Tumor size, histologic grade, number of tumors, lymph node positivity, and lymphovascular invasion are the major prognostic factors adjusted for. Reconstruction following mastectomy is the most likely surgical procedure for the higher socioeconomic and privately insured patients. Mastectomy alone is the most likely surgical procedure for the lower socioeconomic and for public patients. No surgery is the most likely surgical outcome for the lower socioeconomic and the least likely for the higher socioeconomic population. Open biopsy is the most likely diagnostic procedure for the lower socioeconomic and fine needle aspiration for the higher socioeconomic population. Socioeconomic and insurance status, are both independently associated with the types of treatment and diagnostic procedure for women with breast cancer. Opportunities present to investigate an association of these factors with morbidity and survival outcomes.     

Decisional regret after robotic-assisted laparoscopic prostatectomy is higher in African American men

ObjectivesLongitudinal studies report racial disparities in prostate cancer (PCa) including greater incidence, more aggressive tumor biology, and increased cancer-specific mortality in African American (AA) men. Regret concerning primary treatment selection is underevaluated in patients with PCa. We investigated the relationships between clinicopathologic variables across racial and socioeconomic lines following robotic-assisted laparoscopic prostatectomy.Materials and methodsWe assessed treatment decisional regret using a validated questionnaire in a total of 484 white and 72 AA patients with PCa who were followed up for a median of 16.6 months post–robotic-assisted laparoscopic prostatectomy. Socioeconomic status (SES) information was aggregated from 2010 US census zip code data. Perioperative clinicopathologic characteristics and functional outcomes were compared between groups. Univariate and multivariate regression analyses were used to evaluate the influence of race, aggregate SES, and other clinical and demographic characteristics on decisional regret.ResultsThe majority (87.7%) of the population was not regretful of their decision to undergo treatment. However, a greater proportion of AA vs. white patients were regretful (20.6% vs. 11.2%, respectively; P = 0.03). AA and white men were similar on all functional, clinical, and pathologic features with the exception of younger age among AA men (56 vs. 60 y, respectively; P<0.001). Although there were significant differences in SES by race (P<0.001), regret did not differ by SES (β =?1.53; P = 0.15). Race, postoperative sexual dysfunction, pad usage, and length of hospital stay, however, were significantly associated with decisional regret.ConclusionsAA men were more regretful than white men, after adjusting for clinicopathologic characteristics and postoperative functional outcomes.     

Risk of Positive Nonsentinel Nodes in Women with 1–2 Positive Sentinel Nodes Related to Age and Molecular Subtype Approximated by Receptor Status

We examine risk of positive nonsentinel axillary nodes (NSN) and ≥4 positive nodes in patients with 1–2 positive sentinel nodes (SN) by age and tumor subtype approximated by ER, PR, and Her2 receptor status. Review of two institutional databases demonstrated 284 women undergoing breast conservation between 1997 and 2008 for T1‐2 tumors and 1 (229) or 2 (55) positive SN followed by completion dissection. The median number of SN and total axillary nodes removed were 2 (range 1–10) and 14 (range 6–37), respectively. The rate of positive NSNs (p = 0.5) or ≥4 positive nodes (p = 0.6) was not associated with age. NSN were positive in 36% of luminal A, 26% of luminal B, 21% of TN and 38% of Her2+ (p = 0.4). Four or more nodes were present in 17% of luminal A, 13% luminal of B, 0% of TN and 29% of Her2+ (p = 0.1). Microscopic extracapsular extension was significantly associated with having NSNs positive (55% versus 24%, p < 0.0001) and with having total ≥4 nodes positive (33% versus 7%, p < 0.0001). In a population that was largely eligible for ACOSOG Z0011, the risk of positive NSN or ≥4 positive nodes did not vary significantly by age. The TN subgroup had the lowest risk of both positive NSN or ≥4 positive nodes. Several high risk groups with >15% risk for having ≥4 positive nodes were identified. Further data is needed to confirm that ACOSOG Z0011 results are equally applicable to all molecular phenotypes.     

200例慢性肾脏疾病患者营养状况与病程进展的关系

目的探讨主观综合营养评估法（subjective global assessment of nutrition,SGA）评价慢性肾脏疾病（chronic kidney disease,CKD）2～4期患者营养状态并分析其与病程进展的关系。方法对200例CKD患者进行分组：①根据肾小球滤过率（estimated glomerular filtration rate,eG-FR）分为CKD2期组、3期组、4期组;②根据SGA评估分为营养正常组、轻一中度营养不良组和重度营养不良组;③根据病程进展分为进展1组、进展2组、进展3组。于随访第1天、第12个月、第24个月分别检测血红蛋白（hemoglobin,Hb）,白蛋白（albumin,Alb）,前白蛋白（prealbumin,PA）,血清钙（Ca）,血清磷（P）,分析CKD患者的营养状况与病程进展的关系。结果在随访第1天、第12个月、第24个月,CKD4期组与2期组Hb比较有显著性差异;4期组与3期组比较,差异有统计学意义（P〈0．05）,但2期组与3期组比较无统计学差异;CKD2期组第1天与12个月Hb比较差异有统计学意义（P〈O．05）。CKD4期组随访第1天、第12个月、第24个月PA比较,均有统计学差异（P〈0．05）。在第1天、12个月,营养正常组、轻一中度营养不良组、重度营养不良组Alb组间比较,差异有统计学意义;轻一中度营养不良组随访第1天、第12个月、第24个月比较,均有统计学差异（P〈0．05）。重度营养不良组随访第1天、第12个月、第24个月PA比较,均有统计学差异（P〈0．05）。CKD患者不同营养状况与病程进展发生率差异有统计学意义（P〈0．05）,且重度营养不良患者进展3组发生率为92．6％。结论Alb可作为营养状况的评价指标之一。CKD患者PA随着肾功能下降及病程的延长而升高。重度营养不良对CKD患者病程进展影响较大,SGA评估CKD患者的营养状态具有一定临床参考价值。     

A Theory-Based Newsletter Nutrition Education Program Reduces Nutritional Risk and Improves Dietary Intake for Congregate Meal Participants

At-risk older adults need community-based nutrition programs that improve nutritional status and practices. This 6-month study assessed the impact of the traditional Chef Charles (CC) program (Control) compared to a theory-based CC program (Treatment) on nutritional risk (NR), dietary intakes, self-efficacy (SE), food security (FS), and program satisfaction for congregate meal participants. Participants were mostly educated, single, “food secure” White females. NR change for the treatment group was significantly higher (P = 0.042) than the control group. No differences were noted for SE or FS change and program satisfaction between groups. The overall distribution classification levels of FS changed significantly (P &#60; .001) from pre to post. Over half (n = 46, 76.7%) reported making dietary changes and the majority (n = 52, 86.7%) rated CC as good to excellent. Results suggest the theory-based CC program (treatment) is more effective in reducing NR and dietary practices than the traditional CC program (control).     

Do Incest,Depression, Parental Drinking,Serious Romantic Relationships,and Living with Parents Influence Patterns of Substance Use During Emerging Adulthood?

This study examined how incest, depression, parental drinking, relationship status, and living with parents affect patterns of substance use among emerging adults, 18 to 25 years old. The study sample included (n = 11,546) individuals who participated in Waves I, II, and III of the National Longitudinal Study of Adolescent Health (Add Health). The study used separate latent class analysis for males and females to determine how patterns of substance use clustered together. The study identified the following three classes of substance use: heavy, moderate, and normative substance use patterns. Multinomial logistic regression indicated that, for females only, incest histories also nearly doubled the risk of heavy-use class membership. In addition, experiencing depression, being single, and not living with parents serve as risk factors for males and females in the heavy-use group. Conversely, being Black, Hispanic, or living with parents lowered the likelihood of being in the group with the most substance use behaviors (i.e., heavy use). Findings highlight the need for interventions that target depression and female survivors of incest among emerging adults.     

Population pharmacokinetic analysis of axitinib in healthy volunteers

AIMS

Axitinib is a potent and selective second generation inhibitor of vascular endothelial growth factor receptors 1, 2 and 3 approved for second line treatment of advanced renal cell carcinoma. The objectives of this analysis were to assess plasma pharmacokinetics and identify covariates that may explain variability in axitinib disposition following single dose administration in healthy volunteers.

METHODS

Plasma concentration–time data from 337 healthy volunteers in 10 phase I studies were analyzed, using non-linear mixed effects modelling (nonmem) to estimate population pharmacokinetic parameters and evaluate relationships between parameters and food, formulation, demographic factors, measures of renal and hepatic function and metabolic genotypes (UGT1A1*28 and CYP2C19).

RESULTS

A two compartment structural model with first order absorption and lag time best described axitinib pharmacokinetics. Population estimates for systemic clearance (CL), central volume of distribution (V_c), absorption rate constant (k_a) and absolute bioavailability (F) were 17.0 l h⁻¹, 45.3 l, 0.523 h⁻¹ and 46.5%, respectively. With axitinib Form IV, k_a and F increased in the fasted state by 207% and 33.8%, respectively. For Form XLI (marketed formulation), F was 15% lower compared with Form IV. CL was not significantly influenced by any of the covariates studied. Body weight significantly affected V_c, but the effect was within the estimated interindividual variability for V_c.

CONCLUSIONS

The analysis established a model that adequately characterizes axitinib pharmacokinetics in healthy volunteers. V_c was found to increase with body weight. However, no change in plasma exposures is expected with change in body weight; hence no dose adjustment is warranted.     

Family income trajectory during childhood is associated with adolescent cigarette smoking and alcohol use

Background

Although childhood socioeconomic disadvantage has been linked with adolescent tobacco and alcohol use in cross-sectional research, less is known about the influence of changes in socioeconomic status during childhood. Upward socioeconomic mobility may attenuate the negative influence of earlier socioeconomic disadvantage on health, while downward mobility may counter the health benefits of earlier socioeconomic advantage. This study evaluated the influence of common trajectories of family income during childhood on smoking and alcohol use during adolescence.

Methods

Data utilized were part of the 15-year longitudinal Study of Early Child Care and Youth Development. A 5-class trajectory model (two stable, one downward, and two upward income trajectories) was developed previously with this sample (N = 1356). Logistic regression analyses were conducted to determine whether children of the more disadvantaged income trajectories were more likely to engage in tobacco and alcohol use at age 15 relative to those of the most advantaged trajectory.

Results

Family income trajectory was significantly associated with ever-smoking (p = .02) and past-year alcohol use at age 15 years (p = .008). Children from the less advantaged trajectories were more likely to have ever-smoked than children of the most advantaged trajectory (all p's < .05). Children of the downwardly mobile trajectory were more likely to have used alcohol within the past year than children of the most advantaged trajectories as well as the most disadvantaged trajectory (all p's < .05).

Conclusions

Findings indicate that childhood socioeconomic disadvantage influences adolescent smoking, while downward socioeconomic mobility influences adolescent alcohol use.
