Enhanced pancreatic and skin tumorigenesis in cabbage-fed hamsters and mice

Studies were conduded to evaluate the ability of dietary driedcabbage supplements to inhibit pancreatic carcinogenesis inhamsters and skin tumorigenesis in mice. Pancreatic cancer wasinduced by treatment with 40 mg/kg body wt N-nitrosobis-(2oxopropyl)amine(BOP). Cabbage was fed from before carcinogen treatment in lowfat diet and, beginning 1 week after BOP treatment, cabbagewas given in low fat and high fat diets in comparison with therespective non-cabbage containing diets. Dried cabbage was incorporatedat 9 and 11% levels into the low and high fat diets. Feedingcabbage in the high fat diet elevated the yield of BOP-inducedpancreatic ductular cardnoma (1.6 carcinomas/effedive animal)in comparison with that observed in hamsters fed cabbage ina low fat diet or in those given a high fat diet without cabbage, 0.6–0.8 carcinomaa/effedive animal (P 0.05). Furthermore,the incidence of BOP-induced gall bladder adenocadnomm was elevatedin cabbage-fed hamsters irrespedve of dietary fat intake. Effetsof dietary fat and cabbage on food consumption, body weight,and serum T₃ and T₄ values are described. Skin tumorigenesiswas induced in SENCAR mice by 10 nmd 7,12 dlmethylbenz[a]anthracene(DMBA) and promoted beginning 1 week later with twice weeklyapplications of 2 µg 12-O-tetradecanoyl-13-phorbol acetate(TPA). Dried cabbage was incorporated into AIN semi-purifieddiets from before DMBA treatment and throughout TPA treatment.Skin papilloma yield was elevated in DMBA-initiated TPA-promotedmice that were fed diets containing 10% cabbage. Mice fed cabbagedeveloped an average of 8.45 papillomas per mouse following22 weeks of promotion while mice given control diet developed7.25 papillomas per mouse (P < 0.001). Cabbage feeding didnot influence survival, food consumption or body weight of themice. These results suggest the need for further research onthe use of cabbage as a chemopreventive measure.

Human Milk Exosomal MicroRNA: Associations with Maternal Overweight/Obesity and Infant Body Composition at 1 Month of Life

Among all the body fluids, breast milk is one of the richest sources of microRNAs (miRNAs). MiRNAs packaged within the milk exosomes are bioavailable to breastfeeding infants. The role of miRNAs in determining infant growth and the impact of maternal overweight/obesity on human milk (HM) miRNAs is poorly understood. The objectives of this study were to examine the impact of maternal overweight/obesity on select miRNAs (miR-148a, miR-30b, miR-29a, miR-29b, miR-let-7a and miR-32) involved in adipogenesis and glucose metabolism and to examine the relationship of these miRNAs with measures of infant body composition in the first 6 months of life. Milk samples were collected from a cohort of 60 mothers (30 normal-weight [NW] and 30 overweight [OW]/obese [OB]) at 1-month and a subset of 48 of these at 3 months of lactation. Relative abundance of miRNA was determined using real-time PCR. The associations between the miRNAs of interest and infant weight and body composition at one, three, and six months were examined after adjusting for infant gestational age, birth weight, and sex. The abundance of miR-148a and miR-30b was lower by 30% and 42%, respectively, in the OW/OB group than in the NW group at 1 month. miR-148a was negatively associated with infant weight, fat mass, and fat free mass, while miR-30b was positively associated with infant weight, percent body fat, and fat mass at 1 month. Maternal obesity is negatively associated with the content of select miRNAs in human milk. An association of specific miRNAs with infant body composition was observed during the first month of life, suggesting a potential role in the infant’s adaptation to enteral nutrition.

The Health Status of Hispanic Agricultural Workers in Georgia and Florida

To examine the health status of Hispanic agricultural workers in Florida and Georgia. Health data from agricultural workers in the Farm Worker Family Health Program (June 2019) and research studies in Florida (May 2015 and May 2019) were examined. Data from 728 agricultural workers were collected through sociodemographic questionnaire and clinical data. In the Florida sample, 83% were overweight or obese, 70% elevated blood pressure, 60% met the definition of prediabetes. In Georgia, 64% were overweight or obese and 67% had elevated blood pressure. Weak correlations were observed between BMI and systolic blood pressure (unadjusted r?=?0.20), diastolic blood pressure (unadjusted r?=?0.19), and glucose (unadjusted r?=?0.14). Adjusting for age and gender did not show statistically significant correlation between BMI and systolic and diastolic blood pressure or glucose. While BMI has been shown to be strongly associated with high blood pressure and impaired glucose, we found a weak correlation among agricultural workers. Given the common and high use of pesticides and elevated rates of hypertension, impaired glucose, and adiposity in agricultural workers, the public health impact of this relationship may require and lead to occupational reform that protects the health of agricultural workers. Future studies should assess occupational and environmental factors and lifestyle differences between agricultural workers and the general population to better understand these discrepancies in health status.

Management of cervicofacial lymphatic malformations requires a multidisciplinary approach

Background/PurposeCervicofacial lymphatic malformations (CFLM) are rare, potentially life-threatening vascular anomalies, yet reports on multidisciplinary treatment strategies are lacking. We evaluated outcomes for CFLMs following sclerotherapy, surgical resection, and/or medical management.MethodsWe identified children with a CFLM at a vascular anomalies center from 2004 to 2019. Exclusion criteria: retro-orbital malformations, untreated malformations, patients without follow-up. Primary clinical outcome was contour improvement, with significance defined as LM volume reduction of > 50% by cross-sectional imaging.ResultsSixty-three children met inclusion criteria: 35 with macrocystic CFLMs, six with microcystic CFLMs, and 22 with mixed-type malformations. Mean post-intervention follow-up was 27.5 months. Fifty-eight patients underwent sclerotherapy (median: two treatments). Doxycycline and/or bleomycin were used in 95% of patients. After sclerotherapy, 97% of macrocystic CFLMs improved significantly compared to 82% of mixed and 67% of microcystic lesions. Sixteen children underwent surgical resection with 75% significantly improving; two additional patients were successfully treated with sclerotherapy after debulking surgery. Six children received sirolimus for microcystic disease, of which 33% significantly improved.ConclusionSclerotherapy is very effective for macrocystic components of CFLMs, albeit less so for microcystic disease. Microcystic CFLMs frequently require surgical resection. Sirolimus is a helpful therapeutic adjunct, particularly for microcystic lesions, but more study is needed.Level of EvidenceLevel II, prognosis study     

Examining Rules in Friends with Benefits Relationships

Establishing communicative and behavioral boundaries in romantic relationships provides partners with a greater sense of relational stability and certainty. For romantic relationships, these boundaries, such as sexual exclusivity, are relatively straightforward. For casual sex relationships, however, the relational rules are less stable and certain. This exploratory study examined rules in friends with benefits relationships (FWBRs) for 109 college students in the USA. Responses to open-ended questions were collected through an online questionnaire, and data were qualitatively analyzed through an inductive thematic analysis. The data were structured into communication rules, sexual rules, and relational definition rules. Results provide overlap and extension of previous work investigating rules in FWBRs. Notably, participants reported sexual exclusivity as an important rule. Additionally, potentially competing discourses in FWBR rules were best understood through the lens of relational dialectics. Findings reflect a tension in terms of relational work, as partners struggle with maintaining their sexual and friendship relationship while not falling into the “territory” of romantic relationships.

     

IVF - how much more does it cost?

The high cost of some newer drugs will have to be justified by significant clinical improvements. However, not all new drugs are more expensive than older options. These are just some of the findings from a cost analysis of antifungal therapy presented at the International Summit on Cutaneous Antifungal Therapy held in San Francisco late last year. Although preliminary, it has provided a first attempt at comparing costs in a therapeutic area practically devoid of published pharmacoeconomic studies.
