Bed bugs are hematophagous insects that can be problematic in some urban emergency departments. Selleckchem Eprosartan The objective was to determine if red blood cell (RBC) and coagulation indices of bed bug-infested emergency department (ED) patients differed from those of noninfested control patients.

A chart review from a single health system was performed for ED patients between February 1, 2011, and February 1, 2017. Bed bug-infested patients were matched to noninfested control patients on the basis of age, sex, and the presenting ED. Variables were analyzed with the t-test and Pearson χ

test and were modeled with multivariable logistic regression.

The study had 332 bed bug-infested patients and 4952 controls. Infested patients had lower hemoglobin (11.7g/dL vs 12.8g/dL), hematocrit (35.0% vs 37.9%), RBC counts (4.1×10

/L vs 4.4×10

/L), mean corpuscular volume (86.0 vs 87.5fL/cell), and mean corpuscular hemoglobin concentrations (33.2 vs 33.7g/dL) and higher RBC distribution width-coefficient of variation (RDW-CV) (15.2% vs 14.2%) than noninfested patients (all P≤.003). Infested patients were more likely to be anemic (59.5% vs 36.9%) and to have severe anemia (4.4% vs 0.7%) (P<.001 for both). Blood transfusions were more common in those with bed bugs (5.1%) than those without bed bugs (2.3%) (P<.001).

Bed bug infestated patients in the ED are associated with anemia.

Bed bug infestated patients in the ED are associated with anemia.

Despite near equal representation of women in medical schools since 2008, the percentage of women in surgical subspecialties has remained low. Hand surgery accounts for one of the highest percentages of women, at 19%. Ascension to leadership positions has not yet been fully studied among this group. Our study examined whether increased female representation translated to representation at different levels within the organization.

The 2014 to 2018 membership rosters were obtained from the American Society for Surgery of the Hand (ASSH) and compared by gender. Leadership and volunteer committee positions were evaluated as published in the annual ASSH Committee Reference Book. Leadership positions were defined as appointment to committee chair or Council or acceptance to the Young Leaders Program. Rates of engagement were compared for each of the leadership activities. When available, the time for advancement through various leadership positions was also analyzed by gender.

Between 2014 and 2018, the perceas been committed to increasing gender and ethnic diversity. Early analysis demonstrates an increase in women surgeons' participation in early career leadership activities within the society.Finding optimal solutions usually requires multicriteria optimization. The sum of ranking differences (SRD) algorithm can efficiently solve such problems. Its principles and earlier applications will be discussed here, along with meta-analyses of papers published in various subfields of food science, such as analytics in food chemistry, food engineering, food technology, food microbiology, quality control, and sensory analysis. Carefully selected real case studies give an overview of the wide range of applications for multicriteria optimizations, using a free, easy-to-use and validated method. Results are presented and discussed in a way that helps scientists and practitioners, who are less familiar with multicriteria optimization, to integrate the method into their research projects. The utility of SRD, optionally coupled with other statistical methods such as ANOVA, is demonstrated on altogether twelve case studies, covering diverse method comparison and data evaluation scenarios from various subfields of food science.We studied the effect of shockwave processing and subsequent sous vide cooking on meat proteins (molecular size and thermal stability) and muscle structures (molecular, micro- and ultrastructure). Beef briskets were subjected to shockwave (11 kJ/pulse) and were sous vide-cooked at 60 °C for 12 h. Shockwave processing alone decreased the enthalpy and thermal denaturation temperature of the connective tissue proteins (second peak in the DSC thermogram, p less then 0.05) compared to the control raw samples, while the protein gel electrophoresis profile remained unaffected. It led to disorganisation of the sarcomere structure and also modified the protein secondary structure. More severe muscle fibre coagulation and denaturation were observed in the shockwave-treated cooked meat compared to the cooked control. The results show that shockwave processing, with and without sous vide cooking, promotes structural changes in meat, and thus may have the potential to improve the organoleptic quality of the tough meat cuts.Extract of E. camaldulensis was partitioned into aqueous and ethanol fractions by a precipitation and sedimentation-based technique and profiled for phytochemical components. Antimicrobial evaluation yielded inhibitory concentrations of 16-64 and 158-316 µg/mL, and bactericidal concentrations of 32-64 and 316->2528 µg/mL for ethanol and aqueous fractions, respectively. Antioxidant activities evaluated using 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic) acid assays showed IC50 values of 7.07 and 65.67 µg/mL, and 17.96 and 201.3 µg/mL for aqueous and ethanol fractions. Total phenolic content of 9.04 ± 0.26 and 3.58 ± 0.04 GAE/mg fraction, and flavonoid content of 2.07 ± 0.02 and 3.37 ± 0.05 QE/mg fraction were recorded for aqueous and ethanol fractions. At subinhibitory concentrations fractions significantly reduced listeriolysin O-induced haemolysis (p less then 0.05), and ameliorated H2O2-induced toxicity by 8-23 and 15-83%. Nitrite production reduced by 4-17 and 3-14 µM following fractions treatment. The fractions showed bioactive properties, with oxidative stress amelioratory effects, and could be a potentials source of preservatives and functional food additives.This study was designed to investigate quantitatively the inhibition and molecular mechanism of pancreatic α-amylase exhibited by flavonoids from dandelion to reveal its potential use in relieving postprandial hyperglycemia. The results show that the flavonoids reversibly inhibited the α-amylase in a non-competitive manner with Michaelis-Menten constant (Km) and half-inhibitory concentration (IC50) value of 10.51 and 0.0067 mg/mL, respectively. The flavonoids present a strong ability to quench the intrinsic fluorescence of α-amylase through static quenching by forming a complex. The values of the binding site (n) at different temperatures were found to be approximately the unity, indicating the presence of a single class of molecular binding of the dandelion flavonoids on α-amylase. The positive values of enthalpy and entropy change reveal that the binding was predominately driven by hydrophobic interactions. This study suggests a benefit of incorporating the dandelion flavonoids in making functional foods in managing the diet of the diabetes.Nanoencapsulation provides new alternatives for the food industry, enabling a controlled and slow release of active antimicrobial agents, such as essential oils (EO). Poly (butylene adipate-co-terephthalate) (PBAT) nanocapsules loaded with linalool EO were prepared using an extrusion method with 1, 3, and 5% w/v (PBAT to chloroform). Nanocapsules' sizes ranged from 100 to 250 nm and were spherical. The release profile was studied using an ethanoic medium over 24 h, and according to the Korsmeyer-Peppas model, a Fick diffusion mechanism was involved. FT-IR and thermogravimetric analyses confirmed EO encapsulation with an encapsulation efficiency of 55%, 71%, and 74% for 1, 3, and 5%, respectively. The results indicated that encapsulation depended on organic phase concentration, with higher PBAT contents achieving better results. The resulting nanocapsules had antimicrobial activity against E. coli, which could be extended to develop active packaging systems.The development of substrate with high sensitivity and good reproducibility for surface-enhanced Raman scattering (SERS) detection of contaminants in foods has attracted more and more attention. Herein, a stable two-dimensional (2D) Au-Ag core-shell nanorods (Au@Ag NRs) nanoarray substrate with high-performance SERS activity was developed based on interface self-assembly strategy and successfully applied to the detection of thiram in apple sample. A broad linearity range of 0.01-10 mg/L and a low limit of detection of 0.018 mg/L were achieved for thiram solution. The substrate was stable and exhibited satisfactory sensitivity after preserving at ambient temperature for 4 weeks. Furthermore, this method presented the comparable result to that acquired from high-performance liquid chromatography (HPLC) with satisfactory recoveries of 93-116%. The study indicated that the prepared Au@Ag NRs nanoarray substrate was promising for SERS detection of contaminants such as pesticides in foods.Powders made from seed-used pumpkin flesh (SUPF) are potential sources of carotenoids. In this study, unexplored effects of particle size and corn oil on bioaccessible amounts of carotenoids and antioxidant capacity of SUPF powders during in vitro digestion process were investigated. Overall, total carotenoid relative bioaccessibility (TCRB) of 100 mesh-sized powder (100 MP, 15.46%) was higher than that of 18 mesh-sized powder (18 MP, 12.94%). With the addition of 2% corn oil, TCRB increased 108.35% (18 MP) and 88.55% (100 MP), respectively. Lutein (≥27160 µg/100 g) and β-carotene (≥5192 µg/100 g) were main carotenoid monomers in SUPF and significantly correlated with DPPH radical scavenging activity of digestive supernatant (p less then 0.05). Notably, DPPH radical scavenging activity of 18 MP increased 96.54% with corn oil. These results implied that smaller particle size and oil addition could improve bioaccessible amounts of carotenoids and antioxidant capacity of SUPF powders.The contents of phenolic compounds, especially flavonoids, and antioxidant activity of rice (Oryza sativa, Os) and Chinese wild rice (Zizania latifolia, Zl) harvested in China were compared. Zl possessed significantly higher contents of total phenolics, flavonoids, and proanthocyanidins and exhibited higher antioxidant activity than in the Os Xian group, the Os Geng group, and red rice. The flavonoid contents of Os and Zl were compared using a UHPLC-QqQ-MS-based metabolomics approach. A total of 159 flavonoids were identified, among which 78 showed differential expression (72 up-regulated and six down-regulated in the Zl group). The Kyoto Encyclopaedia of Genes and Genomes annotation and classification indicated that the differentially expressed flavonoids were mainly related to anthocyanin biosynthesis. Moreover, candidate genes for flavonoid biosynthesis in Os and Zl were identified in this study. Compared with non-pigmented and red rice, Zl may be more nutritious and is thus considered a better source of natural antioxidants.Eggs' nutritional value has been enhanced by enriching hen's diet with bioactive compounds, but factors influencing bio-accessibility are unspecified. This study investigated the effect of hen breed, diet enrichment, and cooking methods in modulating the egg compounds' bio-accessibility after gastrointestinal (GI) digestion. White Leghorn (WLH) and Rhode Island Red (RIR) hens were fed a corn-soybean-based diet enriched with flaxseed and carotenoids; eggs were collected, cooked, and subjected to simulated GI digestion. The results showed that egg proteins were equally digestible with no change in the degree of hydrolysis (DH). The linolenic fatty acid in enriched-cooked samples remained bio-accessible after GI digestion. The lutein bio-accessibility in enriched eggs decreased after GI digestion except in RIR fried sample. Eggs from WLH and RIR achieved similar peptide content after GI digestion. These results elucidate the bio-accessibility of different bioactive compounds in cooked eggs and the use of eggs as potential functional foods.
