Proteins in soy might have a higher role in cancer prevention than previously expected: soybean protein fractions are more effective MMP-9 inhibitors than non-protein fractions, even in cooked seeds
The search for anticancer MMP-9 inhibitors (MMPIs) in food products has become a major
goal for research. MMPIs in soy have been related only to saponins and isoflavones, but recently, low
specific protein fractions in soybeans were shown to reduce MMP-9 activity as well. The present
work aimed at comparing the MMPI potential of protein fractions (P) and non-protein fractions (NP)
isolated from soybean seeds, before and after soaking and cooking, mimicking dietary exposures.
Reverse and substrate zymography, as well as a fluoregenic DQ gelatin assay were used to evaluate
MMP-9 activities. Colon cancer cell migration and proliferation was also tested in HT29 cells.
Regarding MMP-9 inhibition, proteins in soy presented IC50 values 100 times lower than non-protein
extracts, and remained active after cooking, suggesting that proteins may be more effective MMP-9
inhibitors than non-protein compounds. Using the determined IC50 concentrations, NP fractions
were able to induce higher inhibitions of HT29 cell migration and proliferation, but not through
MMP-9 inhibition, whilst protein fractions were shown to specifically inhibit MMP-9 activity. Overall,
our results show that protein fractions in soybeans might have a higher role in soy-related cancer
prevention as MMPIs than previously expected. Being nontoxic and active at lower concentrations,
the discovery of these heat-resistant specific MMPI proteins in soy can be of significant importance for
cancer preventive diets, particularly considering the increasing use of soy proteins in food products
and the controversy around isoflavones amongst consumersinfo:eu-repo/semantics/publishedVersio
Patterns of Emergency Department Use Among Long-Stay Nursing Home Residents With Differing Levels of Dementia Severity
OBJECTIVES:
To describe emergency department (ED) utilization among long-stay nursing home residents with different levels of dementia severity.
DESIGN:
Retrospective cohort study.
SETTING:
Public Health System.
PARTICIPANTS:
A total of 4491 older adults (age 65 years and older) who were long-stay nursing home residents.
MEASUREMENTS:
Patient demographics, dementia severity, comorbidities, ED visits, ED disposition decisions, and discharge diagnoses.
RESULTS:
Forty-seven percent of all long-stay nursing home residents experienced at least 1 transfer to the ED over the course of a year. At their first ED transfer, 36.4% of the participants were admitted to the hospital, whereas 63.1% of those who visited the ED were not. The median time to first ED visit for the participants with advanced stage dementia was 258 days, whereas it was 250 days for the participants with early to moderate stage dementia and 202 days for the participants with no dementia (P = .0034). Multivariate proportional hazard modeling showed that age, race, number of comorbidities, number of hospitalizations in the year prior, and do not resuscitate status all significantly influenced participants' time to first ED visit (P < .05 for all). After accounting for these effects, dementia severity (P = .66), years in nursing home before qualification (P = .46), and gender (P = .36) lost their significance.
CONCLUSIONS:
This study confirms high rates of transfer of long-stay nursing home residents, with nearly one-half of the participants experiencing at least 1 ED visit over the course of a year. Although dementia severity is not a predictor of time to ED use in our analyses, other factors that influence ED use are readily identifiable. Nursing home providers should be aware of these factors when developing strategies that meet patient care goals and avoid transfer from the nursing home to the ED
Diarrheal disease risk in rural Bangladesh decreases as tubewell density increases: a zero-inflated and geographically weighted analysis
Abstract Background This study investigates the impact of tubewell user density on cholera and shigellosis events in Matlab, Bangladesh between 2002 and 2004. Household-level demographic, health, and water infrastructure data were incorporated into a local geographic information systems (GIS) database. Geographically-weighted regression (GWR) models were constructed to identify spatial variation of relationships across the study area. Zero-inflated negative binomial regression models were run to simultaneously measure the likelihood of increased magnitude of disease events and the likelihood of zero cholera or shigellosis events. The aim of this study was to examine the effect of tubewell density on both the occurrence of diarrheal disease and the magnitude of diarrheal disease incidence. Results In Matlab, households with greater tubewell density were more likely to report zero cholera or shigellosis events. Results for both cholera and shigellosis GWR models suggest that tubewell density effects are spatially stationary and the use of non-spatial statistical methods is appropriate. Conclusions Increasing the amount of drinking water available to households through increased density of tubewells contributed to lower reports of cholera and shigellosis events in rural Bangladesh. Our findings demonstrate the importance of tubewell installation and access to groundwater in reducing diarrheal disease events in the developing world
Does Nonrandom Nest Placement Imply Nonrandom Nest Predation?: a Reply
In response to the critique by Schmidt and Whelan (Condor 101 (4): 916-920, 1999), we find that the relationship between nest success and tree selectivity is dependent upon inclusion or exclusion of particular tree species, whether or not years are pooled, and the selectivity index used. We question their use of point estimates of nest success with extremely high variances, defend our index, question the application of the Chesson (1983) index to our data, and explain the need to analyze years separately. Bottomland hardwood forest systems are extremely variable; hydroperiods alter the suitability of nesting substrates, availability of alternative food, and behavior of predators and their prey. Given these features, actively searching for Acadian Flycatcher (Empidonax virescens) nests is seldom an efficient predator foraging strategy. Therefore, these predation events are best described as random; nests are principally encountered opportunistically by generalist predators while searching for other prey

Association between Food Insecurity and Procurement Methods among People Living with HIV in a High Resource Setting
Objective: People living with HIV in high-resource settings suffer severe levels of food insecurity; however, limited evidence exists regarding dietary intake and sub-components that characterize food insecurity (i.e. food quantity, quality, safety or procurement) in this population. We examined the prevalence and characteristics of food insecurity among people living with HIV across British Columbia, Canada. Design: This cross-sectional analysis was conducted within a national community-based research initiative. Methods: Food security was measured using the Health Canada Household Food Security Scale Module. Logistic regression was used to determine key independent predictors of food insecurity, controlling for potential confounders. Results: Of 262 participants, 192 (73%) reported food insecurity. Sub-components associated with food insecurity in bivariate analysis included: < RDI consumption of protein (p = 0.046); being sick from spoiled/unsafe food in the past six months (p = 0.010); and procurement of food using non-traditional methods (p <0.05). In multivariable analyses, factors significantly associated with food insecurity included: procurement of food using non-traditional methods [AOR = 11.11, 95% CI: 4.79–25.68, p = <0.001]; younger age [AOR = 0.92, 95% CI: 0.86–0.96, p = <0.001]; unstable housing [AOR = 4.46, 95% CI: 1.15–17.36, p = 0.031]; household gross annual income [AOR = 4.49, 95% CI: 1.74–11.60, p = 0.002]; and symptoms of depression [AOR = 2.73, 95% CI: 1.25–5.96, p = 0.012]. Conclusions: Food insecurity among people living with HIV in British Columbia is characterized by poor dietary quality and food procurement methods. Notably, participants who reported procuring in non-traditional manners were over 10 times more likely to be food insecure. These findings suggest a need for tailored food security and social support interventions in this setting
