Abstract
OBJECTIVE To examine differences in diet and food purchasing behaviors between Black and White older women living in urban neighborhoods. DESIGN Cross-sectional observational study. SETTING Urban neighborhoods in Washington, DC, USA. PARTICIPANTS Community-dwelling White and Black women of age 65 and older. MEASUREMENTS Participants were queried on diet via 24-hour recalls, food purchasing habits, their use of neighborhood resources and local travel patterns. Frequency and location of self-reported food purchasing and consumption were compared by race. RESULTS In 2014 and 2015, 49 White and 44 Black older women were enrolled in the study. Compared to Whites, Blacks reported lower daily caloric intake (mean (SD) 1314 (404) vs. 1529 (448), p=0.02), with a higher percent of calories from protein and fat 1.8 (7.0), p=0.03), and a slightly higher polyunsaturated to saturated fat ratio (p=0.05). Blacks had substantially lower alternate healthy eating index (AHEI) (33.5 (10.2) vs. 43.9 (10.8) of 80 possible points, p<0.001), daily intake (grams) of total fiber (15.3 (8.1) vs. 22.9 (8.5), p<0.001), insoluble fiber (10.8 (6.9) vs. 15.9 (6.5), p<0.001), and soluble fiber (4.5 (2.0) vs. 6.9 (2.8), p<0.001). Blacks had lower intake of micronutrients, alcohol and caffeine. Blacks shopped for groceries less often (4.4 (3.0) vs. 6.2 (3.0) monthly; p=0.006) and spent a longer time traveling to stores (15.8 (9.1) vs. 11.5 (7.2) minutes per trip, p=0.02). A lower percent of Blacks walked to stores (14% vs. 40%, p=0.003) and a higher percent of Blacks rode in a car with someone else (33% vs. 6%, p<0.001). CONCLUSIONS In an urban setting, food consumption and purchasing behaviors differed substantially between older Black and White women, which should be further investigated and considered to promote healthy eating in older populations.

Abstract
BACKGROUND Odontogenic myxoma is a benign odontogenic tumour of the jaw [1]. This tumour often presents as an asymptomatic expansile lesion without sensory nerve changes [2]. It is thought to arise from mesenchymal origin with cells of microscopic similarity to dental pulp and follicle [3]. Radiographically it presents most often as a multiloculated radiolucency [2]. It is a locally aggressive lesion which may require extensive treatment to prevent recurrence. METHOD The authors present the case of a 13-year-old boy with an extensive lesion in the maxilla. CONCLUSION We discuss various treatment approaches for management of this tumour.

Abstract
Abstract
Background: Recent multi-center trial results are concerning for the ability to identify SLNs after NCT. SLN localization was shown to be less successful (80%) after NCT when compared with no NCT (99%) (SENTINA), and the SLN identification rate in Z1071 in which all patients received NCT was 93%.
Purpose: To examine the effect of NCT, patient and disease characteristics, imaging and surgical technique on SLN localization rates in breast cancer patients undergoing chemotherapy.
Methods: Retrospective, single institution study was performed on patients who underwent surgery for breast cancer from January 2008 to December 2013. All patients who underwent SLN biopsy and either adjuvant chemotherapy (ACT) or NCT, were included. All patients underwent lymphoscintigraphy, and SLN biopsy was performed with the definitive breast surgery.
Results: 68 patients underwent NCT, and 133 underwent ACT. Our SLN localization rate was 198/201 (98.5%) overall; 98.6% (67 of 68) with NCT and 97.7% (130/133) with ACT (p=1.0). Compared with the NCT group, the ACT patients were significantly older, white, with more ER/PR positive tumors. The NCT group had more positive nodes on preop imaging (64% v. 20%, p<0.001), FNA (82% v. 22%, p<0.001), and a lower use of blue dye (37% v. 61%, p=0.05) but there were no differences in the number of SLN removed (1.43 v. 1.33 p=0.32), or nodes that were positive on intraoperative evaluation (30 v. 33%, p=0.75). Comparing the patients who had successful and failed SLN localization, there were no differences in demographics, tumor type, Stage, prior breast surgery, preoperative node positivity on imaging or FNA or timing of chemotherapy.
Conclusion: In this single institution series, SLN non-localization was a rare event and not associated with NCT. We were unable to identify any patient or disease characteristics, imaging or surgical techniques associated with SLN non-localization. The etiology of the lower SLN identification rates with NCT in multi-institutional trials remains to be elucidated.

Abstract
Familial occurrence of distal foregut atresia (DFA) (Type 1) is rare. Diagnosis is based upon the clinical symptomatology and confirmed by radiological studies, surgery and histology. A number of reports have described families in which several family members have been involved and suggested an autosomal recessive mode of inheritance. Little is known about the underlying genetic causes or indeed the likely pathogenic mechanism. We report a family in which there are five affected cases including three siblings where the DFA appears to be inherited in an autosomal dominant inheritance pattern with reduced penetrance.

Abstract
BACKGROUND In non-randomised evaluations of public-health interventions, statistical methods to control confounding will usually be required. We review approaches to the control of confounding and discuss issues in drawing causal inference from these studies. METHODS Non-systematic review of literature and mathematical data-simulation. RESULTS Standard stratification and regression techniques will often be appropriate, but propensity scores may be useful where many confounders need to be controlled, and data are limited. All these techniques require that key putative confounders are measured accurately. Instrumental variables offer, in theory, a solution to the problem of unknown or unmeasured confounders, but identifying an instrument which meets the required conditions will often be challenging. Obtaining measurements of the outcome variable in both intervention and control groups before the intervention is introduced allows balance to be assessed, and these data may be used to help control confounding. However, imbalance in outcome measures at baseline poses challenges for the analysis and interpretation of the evaluation, highlighting the value of adopting a design strategy that maximises the likelihood of achieving balance. Finally, when it is not possible to have any concurrent control group, making multiple measures of outcome pre- and postintervention can enable the estimation of intervention effects with appropriate statistical models. CONCLUSION For non-randomised designs, careful statistical analysis can help reduce bias by confounding in estimating intervention effects. However, investigators must report their methods thoroughly and be conscious and critical of the assumptions they must make whenever they adopt these designs.

Abstract
Extrarenal Wilms tumor (ERWT) is a well-established entity which most commonly arises within the genitourinary tract, including intracoelomic paranephric soft tissue. Rarely, ERWT arises within teratoma, and it tends to occur predominantly in distinct settings, such as females with spinal defects and males with testicular teratomas. We report a unique ERWT arising within an extracoelomic teratoma of the paraspinal musculature, thereby expanding the range of reported locations for this unusual tumor.

Abstract
Genetic diversity is the foundation of any crop improvement program, but the most cultivated Upland cotton [Gossypium hirsutum L., 2n = 52, genomic formula 2(AD)(1)] has a very narrow gene pool resulting from its evolutionary origin and domestication history. Cultivars of this cotton species (G. hirsutum L.) are prized for their combination of exceptional yield, other agronomic traits, and good fiber properties, whereas the other cultivated 52-chromosome species, G. barbadense L. [2n = 52, genomic formula 2(AD)(2)], is widely regarded as having the opposite attributes. It has exceptionally good fiber qualities, but generally lower yield and less desirable agronomic traits. Breeders have long aspired to combine the best attributes of G. hirsutum and G. barbadense, but have had limited success. F(1) hybrids are readily created and largely fertile, so the limited success may be due to cryptic biological and technical challenges associated with the conventional methods of interspecific introgression. We have developed a complementary alternative approach for introgression based on chromosome substitution line, followed by increasingly sophisticated genetic analyses of chromosome-derived families to describe the inheritance and breeding values of the chromosome substitution lines. Here, we analyze fiber quality traits of progeny families from a partial diallel crossing scheme among selected chromosome substitution lines (CS-B lines). The results provide a more detailed and precise QTL dissection of fiber traits, and an opportunity to examine allelic interaction effects between two substituted chromosomes versus one substituted chromosome. This approach creates new germplasm based on pair wise combinations of quasi-isogenic chromosome substitutions. The relative genetic simplicity of two-chromosome interactions departs significantly from complex or RIL-based populations, in which huge numbers of loci are segregating in all 26 chromosome pairs. Data were analyzed according to the ADAA genetic model, which revealed significant additive, dominance, and additive-by-additive epistasis effects on all of the fiber quality traits associated with the substituted chromosome or chromosome arm of CS-B lines. Fiber of line 3-79, the donor parent for the substituted chromosomes, had the highest Upper Half Mean length (UHM), uniformity ratio, strength, elongation, and lowest micronaire among all parents and hybrids. CS-B16 and CS-B25 had significant additive effects for all fiber traits. Assuming a uniform genetic background of the CS-B lines, the comparative analysis of the double-heterozygous hybrid combinations (CS-B × CS-B) versus their respective single heterozygous combinations (CS-B × TM-1) demonstrated that interspecific epistatic effects between the genes in the chromosomes played a major role in most of the fiber quality traits. Results showed that fiber of several hybrids including CS-B16 × CS-B22Lo, CS-B16 × CS-B25 and CS-B16 × TM-1 had significantly greater dominance effects for elongation and hybrid CS-B16 × CS-B17 had higher fiber strength than their parental lines. Multiple antagonistic genetic effects were also present for fiber quality traits associated with most of the substituted chromosomes and chromosome arms. Results from this study highlight the vital importance of epistasis in fiber quality traits and detected novel effects of some cryptic beneficial alleles affecting fiber quality on the 3-79 chromosomes, whose effects were not detected in the 3-79 parental lines.

Abstract
We report a case of an 8-month-old child with a primitive myxoid mesenchymal tumor of infancy arising in the thenar eminence. The lesion recurred after conservative excision and was ultimately nonresponsive to chemotherapy, necessitating partial amputation. The patient remains free of disease 5 years after this radical surgery. This is the 1st report of such a tumor since it was initially described by Alaggio and colleagues in 2006. The pathologic differential diagnosis is discussed.

Abstract
In Zimbabwe around 1.1 million children have been orphaned due to AIDS. We conducted a survey among school-attending youth in rural south-eastern Zimbabwe in 2003, and examined the association between orphaning and risk of HIV. We enrolled 30 communities in three provinces. All students attending Year 2 of secondary school were eligible. Each completed a questionnaire and provided a finger-prick blood specimen for testing for HIV-1 and HSV-2 antibodies. Female participants were tested for pregnancy. Six thousand seven hundred and ninety-one participants were recruited (87% of eligible); 35% had lost one or both parents (20% of participants had lost their father; 6% their mother; and 9% both parents). Orphans were not poorer than non-orphans based on reported access to income, household structure and ownership of assets. There was strong evidence that orphans, and particularly those who had lost both parents, were at increased sexual risk, being more likely to have experienced early sexual debut; to have been forced to have sex; and less likely to have used condoms. Fifty-one students were HIV positive (0.75%). Orphans were three times more likely to be HIV infected than non-orphans (adjusted odds ratio = 3.4; 95% confidence interval: 1.8-6.6). Over 60% of those HIV positive were orphaned. Among school-going youth, the rates of orphaning were very high; there was a strong association between orphaning and increased risk of HIV, and evidence of greater sexual risk taking among orphans. It is essential that we understand the mechanisms by which orphaned children are at increased risk of HIV in order to target prevention and support appropriately.

Abstract
The objectives were to study the association between metabolic genes involved in alcohol metabolism (CYP2E1 RsaI, CYP2E1 DraI, ADH1C, NQO1) and alcohol consumption in a large sample of healthy controls. Healthy subjects were selected from the International Collaborative Study on Genetic Susceptibility to Environmental Carcinogens (GSEC). Subjects with information on both alcohol consumption and at least one of the studied polymorphisms were included in the analysis (n=2224). Information on the amount of alcohol consumption was available for a subset of subjects (n=844). None of the studied genes was significantly associated with drinking habits. A significant heterogeneity with age was observed when studying the association between CYP2E1 RsaI and alcohol drinking. CYP2E1 RsaI polymorphism was significantly associated with being a never drinker at older ages (odds ratio [OR] 2.4, 95% confidence interval [CI] 1.2-4.8; at ages above 68 years), while the association was reversed at ages below 47 years (OR 0.5, 95% CI 0.2-1.4). For subjects with detailed information on alcohol intake, no association between alcohol quantity and polymorphisms in metabolic genes was observed; subjects carrying the NQO1 polymorphism tended to drink more than subjects carrying the wild-type alleles. Therefore, no significant association between CYP2E1 RsaI, CYP2E1 DraI, ADH1C, NQO1 polymorphisms and alcohol consumption was observed in healthy controls.

METHODS 1305 HSV-2 seropositive women aged 16-35 years working in bars, guesthouses and similar facilities were interviewed, examined and tested for HIV, syphilis, Neisseria gonorrhoeae, Chlamydia trachomatis, BV, candidiasis and trichomoniasis. Factors associated with BV were analysed using logistic regression to estimate odds ratios and 95% confidence intervals. RESULTS BV prevalence was 62.9%; prevalence of Nugent score 9-10 was 16.1%. Independent risk factors for BV were work facility type, fewer dependents, increasing alcohol consumption, sex in the last week (adjusted OR 2.03; 95% CI 1.57 to 2.62), using cloths or cotton wool for menstrual hygiene, HIV (adjusted OR 1.41; 95% CI 1.09 to 1.83) and Trichomonas vaginalis infection. There was no association between BV and the frequency or method of vaginal cleansing. However, BV was less prevalent among women who reported inserting substances to dry the vagina for sex (adjusted OR 0.44; 95% CI 0.25 to 0.75). CONCLUSION BV was extremely prevalent among our study population of HSV-2 positive female facility workers in North-western Tanzania. Although recent sex was associated with increased BV prevalence, vaginal drying was associated with lower BV prevalence. Further studies of the effects of specific practices on vaginal flora are warranted.
