Trends in Body Mass Index among Ohio's Third-Grade Children: 2004-2005 to 2009-2010

Substantial variation across states in the prevalence and trends in childhood overweight and obesity indicate a need for state-specific surveillance to make state comparisons to national estimates and identify high-risk populations. The purpose of this study was to examine body mass index (BMI) trends among third-grade children in Ohio between the 2004-2005 and 2009-2010 school years and examine changes in prevalence of obesity by specific demographic subgroups. Third-grade children (n=33,672) were directly weighed and measured throughout the school years by trained health care professionals. Trends in overweight/obesity (≥85th percentile of BMI by age/sex), obesity (≥95th percentile), and obesity level 2 (≥97th percentile) over five time periods (2004-2005, 2006-2007, 2007-2008, 2008-2009, 2009-2010) were modeled using logistic regression, accounting for the survey design and adjusting for sex, race/ethnicity, National School Lunch Program (NSLP) participation, and age. Differences in these BMI categories were also examined by these subgroups. BMI estimates did not demonstrate a statistically significant trend over the five time periods for overweight/obesity (34% to 36%), obesity (18% to 20%), or obesity level 2 (12% to 14%). However, increases in overweight/obesity prevalence were found in Hispanic children (37.8% vs 53.1%; P<0.01). Decreases in obesity (16.6% vs 14.1%; P=0.02) and obesity level 2 (11.3% vs 9.3%; P=0.02) were found among children not participating in NSLP and residing in suburban counties (obesity [17.3% vs 14.7%; P=0.03] and obesity level 2 [11.8% vs 9.8%; P=0.05]). Finally, decreases in overweight/obesity and obesity level 2 among boys were observed (15% vs 12.9%; P=0.02). Despite no significant overall trends in overweight/obesity, obesity, or obesity level 2 between 2004 and 2010, prevalence changed among specific subgroups. Obesity prevention efforts should be widespread and include special emphasis on groups experiencing increases or no change in prevalence.     

Retropubic and Transobturator Slings: Still Useful or Should All Patients Be Treated with Mini-slings?

Traditional retropubic and transobturator midurethral slings are reliable, safe, and effective treatments for stress urinary incontinence. Unfortunately, they also are associated with rare but severe complications, such as bladder or bowel perforation, vascular injury, nerve damage, and/or groin muscle pain that can occur with the blind passage of trocars. To maintain efficacy and patient satisfaction while avoiding such complications, minimally invasive mini-slings have been developed. These smaller mini-slings can be placed through a single vaginal incision at the level of the midurethra without trocars. Mini-slings often are performed as an outpatient surgery, with minimal morbidity, pain, and quick patient recovery. With continued refinement and surgeon experience, mini-slings potentially may be performed safely in the office setting under local anesthesia while maintaining the efficacy of traditional slings.     

Effects on survival of menstrual cycle phase of adjuvant surgical oophorectomy in premenopausal women with breast cancer

Adjuvant surgical oophorectomy is an effective and remarkably cost effective treatment for premenopausal women with hormone receptor positive operable breast cancer. Previously published secondary analyses indicated a survival benefit for patients whose surgery was performed in the luteal phase of the menstrual cycle as opposed to the follicular. This study utilizes additional follow-up and more fully examines this hypothesis and the general implications of long-term follow-up on trial design. Beginning in 1993 we recruited women to a multicenter randomized clinical trial of adjuvant surgical oophorectomy and tamoxifen for 5 years. We recorded the reported day 1 of the patients’ last menstrual cycle on the day of their adjuvant surgery. We conducted secondary analyses of the association of history-estimated luteal or follicular phase oophorectomy surgery with disease-free and overall survival. In multivariable Cox analyses, disease-free survival (DFS) exhibited a positive trend and overall survival (OS) showed a significant improvement in patients whose surgery was estimated to have occurred in the luteal phase of the menstrual cycle compared to the follicular (HR for DFS: 0.66, 95% CI: 0.37–1.16; HR for OS: 0.49, 95% CI: 0.27–0.88). From the hazard function plots, it appears that the luteal phase surgery effect on DFS diminishes after 6 years of follow-up. In conclusion, adjuvant surgical oophorectomy during the luteal phase of the menstrual cycle resulted in a reduced hazard of recurrence as compared to oophorectomy in the follicular phase during the first 5.5 years of follow-up. The practical and biological implications of these findings deserve rigorous evaluation in clinical trials.     

Eosinophilic esophagitis: an increasingly recognized cause of dysphagia, food impaction, and refractory heartburn

Eosinophilic esophagitis is an increasingly recognized cause of a variety of esophageal symptoms, including dysphagia, food impaction, atypical chest pain, and heartburn that does not respond to medical therapy. Its cause is unknown, but allergic and immune-mediated mechanisms similar to those of asthma and other atopic diseases are implicated.     

Prediction of adenocarcinoma in esophagectomy specimens based upon analysis of preresection biopsies of Barrett esophagus with at least high-grade dysplasia: a comparison of 2 systems

Distinguishing Barrett esophagus with high-grade dysplasia (BE-HGD) from intramucosal and submucosal adenocarcinomas on biopsies is challenging, yet important, in the choice of therapy. The current study evaluates preresection biopsies from patients who underwent esophagectomy for at least BE-HGD, to compare the recently published histologic categories by the University of Michigan (UM) and Cleveland Clinic (CC), correlate preresection and final resection diagnosis, and identify histologic features in biopsies that might be predictive of adenocarcinoma on esophagectomy. A total of 112 cases with a consensus biopsy diagnosis (agreement by ≥4 of 7 gastrointestinal pathologists) were statistically analyzed to identify histologic features that predicted adenocarcinoma on resection. Applying the UM criteria to the biopsy series showed excellent agreement with the CC system (κ=0.86) and significant correlation between preoperative and esophagectomy diagnoses (P<0.001). The likelihood of finding carcinoma on resection was significantly higher with the category of HGD with marked glandular distortion cannot exclude intramucosal adenocarcinoma [CC; odd ratio (OR), 2.8; P=0.046] or HGD suspicious for adenocarcinoma (UM; OR, 4.3; P=0.008), compared to HGD alone. The presence of "never-ending" glands (OR, 3.7; P=0.008), sheet-like growth (P<0.001), angulated glands (OR, 8.5; P<0.001), ≥3 dilated glands with intraluminal debris (OR, 2.6; P=0.05), and >1 focus of single-cell infiltration into the lamina propria (OR, 8.9; P<0.001) increased the odds of finding carcinoma on resection. The latter 2 variables remained independent predictors of adenocarcinoma in multivariable analysis. In conclusion, the CC and UM systems show excellent agreement and define histologic categories that can improve prediction of adenocarcinoma on resection.     

Esophageal carcinoma cuniculatum: report of 9 cases

Carcinoma cuniculatum, a unique variant of well-differentiated squamous cell carcinoma, has been only rarely reported in the esophagus. We report 9 cases of esophageal carcinoma cuniculatum diagnosed on esophagectomy specimens in 7 men and 2 women during a 20-year period. All but 1 of the patients presented with persistent or progressive dysphagia. All patients had an esophageal mass or lesion on endoscopic examination. In 8 cases (88.8%), the tumor was located in the distal esophagus. Burrowing was noted on the tumor surface in 2 recent cases on macroscopic examination. All carcinomas were invasive either at the mucosa (n=2), submucosa (n=1), muscularis propria (n=4), adventitia (n=3), or adventitia and lung (n=1). All carcinomas demonstrated a common histologic pattern characterized by hyperkeratosis, acanthosis, dyskeratosis, abnormal keratinization, keratin-filled cyst/furrows, koilocyte-like cells, intraepithelial neutrophils, and focal cytologic atypia. In situ hybridization for human papillomavirus subtypes was negative in all 10 tumors tested. None of the cases showed lymph node metastasis. Two patients died postoperatively due to complications. The remaining patients were followed up for a median duration of 84 months (48 to 214 mo). During the follow-up period, 3 patients died 49, 66, and 214 months after esophagectomy at the ages of 66, 68, and 91 years, respectively; death in these 3 cases was not related to recurrence/metastases of esophageal cancer. Four patients were alive without disease at 48, 49, 84, and 87 months after curative resection. Our report identifies a common histomorphologic pattern of esophageal carcinoma cuniculatum and supports the fact that surgical resection of the tumor by esophagectomy provides long-term survival even in patients with T3 tumor.     

Understanding pediatricians' views toward school-based BMI screening in Massachusetts: a pilot study

BACKGROUND: Massachusetts (MA) mandated body mass index (BMI) screening in schools in 2010. However, little is known about pediatricians' views on school‐based screening or how the pediatricians' perspectives might affect the school‐based screening process. We assessed MA pediatricians' knowledge, attitudes, beliefs, and practices concerning BMI screening. METHODS: An anonymous Web‐based survey was completed by 286 members of the MA Chapter of the American Academy of Pediatrics who provided primary care (40% response rate). RESULTS: Support for school‐based BMI screening was mixed. While 16.1% strongly supported it, 12.2% strongly opposed it. About one fifth (20.2%) believed school‐based screening would improve communication between schools and pediatricians; 23.0% believed school‐based screening would help with patient care. More (32.2%) believed screening in schools would facilitate communication with families. In contrast, pediatricians embraced BMI screening in practice: 91.6% calculated and 85.7% plotted BMI at every well child visit. Pediatricians in urban practices, particularly inner city, had more positive attitudes toward BMI screening in schools, even when adjusting for respondent demographics, practice setting, and proportion of patients in the practice who were overweight/obese (p < .001). CONCLUSION: These data suggest MA pediatricians use BMI screening and support its clinical utility. However, support for school‐based BMI screening was mixed. Urban‐based pediatricians in this sample held more positive beliefs about screening in schools. Although active collaboration between schools and pediatricians would likely help to ensure that the screenings have a positive impact on child health regardless of location, it may be easier for urban‐based schools and pediatricians to be successful in developing partnerships.
