Design of bioprocesses for waste carbon valorization requires quantification of steady-state carbon flows. Here, steady-state quantification of autotrophic chemostats containing Clostridium autoethanogenum grown on CO2 and H2 revealed that captured carbon (460 ± 80 mmol/gDCW/day) had a significant distribution to ethanol (54 ± 3 C-mol% with a 2.4 ± 0.3 g/L titer). We were impressed with this initial result, but also observed limitations to biomass concentration and growth rate. Metabolic modeling predicted culture performance and indicated significant metabolic adjustments when compared to fermentation with CO as the carbon source. Moreover, modeling highlighted flux to pyruvate, and subsequently reduced ferredoxin, as a target for improving CO2 and H2 fermentation. Supplementation with a small amount of CO enabled co-utilization with CO2, and enhanced CO2 fermentation performance significantly, while maintaining an industrially relevant product profile. Additionally, the highest specific flux through the Wood-Ljungdahl pathway was observed during co-utilization of CO2 and CO. Furthermore, the addition of CO led to superior CO2-valorizing characteristics (9.7 ± 0.4 g/L ethanol with a 66 ± 2 C-mol% distribution, and 540 ± 20 mmol CO2/gDCW/day). Similar industrial processes are commercial or currently being scaled up, indicating CO-supplemented CO2 and H2 fermentation has high potential for sustainable fuel and chemical production. This work also provides a reference dataset to advance our understanding of CO2 gas fermentation, which can contribute to mitigating climate change.

However, the epidemiologic characteristics of H. influenzae in Shanghai are still unavailable. Objective To determine the serotype distribution, antimicrobial resistance and multilocus sequence type (MLST) of H. influenzae in adult patients in Shanghai. Methods A total of 51 clinical isolates from adult patients were consecutively collected. Serotypes were determined according to specific capsule gene, bexA, amplified by PCR. Antimicrobial susceptibility test was carried out by the broth microdilution method. β-lactamase production was detected by cefinase disk and the ftsI gene were amplified and sequenced to determine the penicillin binding protein 3 (PBP3) mutation. Molecular epidemiology was performed by MLST analyses. Results All isolates studied were nontypeable H. influenzae (NTHi) and three of them (5.88%) caused invasive infection. The resistant rates of ampicillin and trimethoprim/sulfamethoxazole were both 45.10%. One third of these isolates produced TEM-1 type β-lactamase and 11.76% were β-lactamase negative ampicillin resistant strains (BLNAR). The PBP3 mutation was detected in 74.51% of the isolates, of which 12 belonged to group III. A total of 36 sequence types (STs) were identified among all isolates. Four isolates of ST103 (7.84%) all produced β-lactamase without mutation of PBP3. Conclusion H. influenzae infections among adults in Shanghai are predominately caused by NTHi with genetic diversity among adult patients. The prevalence of both β-lactamase production and PBP3 mutation may contribute to high ampicillin resistance rate in Shanghai.

Methods All students who completed the in-person Certificate Program between 2008 and 2015 (n = 71), or the online Certificate Program between 2016 and 2017 (n = 13), were eligible for our study. We assessed the potential impact of the Certificate Program on the professional development of trainees, through participant surveys on their self-reported level of comfort with pre-defined competencies, and on academic productivity. Results Of eligible trainees, 54 in-person (77%) and 13 online (100%) Certificate Program participants completed surveys. In-person trainees reported a total of 147 implementation science-related publications in peer-reviewed journals (median 3 publications/trainee, IQR 1-15). Thirty-four trainees (63%) reported being a Principal Investigator (PI) of 64 funded implementation science-related grants (median 2 grants/trainee, IQR 1-4). Fifteen percent (15%, n = 8) of participants reported receiving an NIH grant on which they were the PI, including R01 or P01 level funding (n = 4, 7%) and K awards (n = 3, 6%). Both in-person and online trainees reported median high to moderate confidence for all 12 competencies assessed. Confidence waned in skills aligning with later stages of implementation research for all trainees. Conclusion The moderate to high confidence in all competencies assessed and reported high level of academic productivity support the benefits of intensive, graduate-level training focused on applied methods to support career development of implementation scientists.

This cross-sectional study aimed to determine whether maternal infections, nutrient deficiencies and inflammation (MINDI) were associated with four measures of maternal blood pressure (BP) and to determine their association with symphysis-fundal-height (SFH). Methods Environmental and dietary factors, intake of iron and a multiple-nutrient supplement (MNS), markers of inflammation, protein, anemia, folate, vitamins B12, A and D status, and urogenital, skin, oral and intestinal nematode infections were measured in indigenous pregnant Panamanian women. Stepwise multiple linear and logistic regression models explored determinants of systolic and diastolic blood pressure (SBP, DBP), hypotension (SBP less then 100 and DBP less then 60), mean arterial pressure (MAP), elevated MAP (eMAP), and pulse pressure (PP). Associations of BP with in and cytokines both raised, and lowered BP indices. The presence of eMAP identified pregnant women at risk of hypertension whereas low PP was associated with lower SFH. Therefore, MAP and PP may help in detecting women at risk of adverse pregnancy outcomes in settings with limited access to technology.

Loss-of-function mutations in the electron transfer flavoprotein dehydrogenase (ETFDH) gene are associated with MADD. Disease-causing synonymous variants in the ETFDH gene have not been reported so far. Methods We reported the clinical course of a Chinese girl who was diagnosed with late-onset MADD by the whole exome sequencing. The effects of variants on mRNA splicing were analyzed through transcript analysis in vivo and minigene splice assay in vitro. Results The 6-month-old girl initially showed muscle weakness, muscular hypotonia, mild myogenic damage, and fatty liver. The blood and urine metabolic screening by tandem mass spectrometry suggested MADD. Molecular analysis of ETFDH gene revealed two novel heterozygous variants, a frameshift mutation c.1812delG (p.V605Yfs*34) in exon 13 and a synonymous variant c.579A>G (p.E193E) in exon 5. The transcript analysis in vivo exhibited that the synonymous variant c.579A>G caused exon 5 skipping. The minigene splice assay in vitro confirmed the alteration of ETFDH mRNA splicing which could lead to the production of a truncated protein. Supplementation of riboflavin, carnitine and low-fat diet improved the clinical symptoms. Conclusion We firstly report a rare case of MADD with a pathogenic synonymous variant in the ETFDH gene which highlights the importance and necessity of bioinformatic analysis and functional testing for synonymous variants when searching for causative gene mutations. The results expand the spectrum of pathogenic variants in MADD.

The „one size fits all” approach is giving way to a „targeted approach,” based on the identification of the patient’s phenotype. Thus, the approach of nutritional management of food allergy has moved on from simply being „yes or no” to „how much?”, „in which form?” and „for which patients?” Different factors should be considered in order to make a patient-tailored nutritional plan in clinical practice. Tailored nutritional plans may help to reduce the nutritional, social and economic burden of food allergy.

Methods Patients (≤ 18 years old) undergoing surgical treatment for primary parotid MEC were enrolled from multiple clinical centers retrospectively. The χ2-test was used to analyze the associations between clinicopathological variables and the NLR. The main study endpoints were recurrence-free survival (RFS) and disease-specific survival (DSS). The prognostic value of NLR was assessed by Kaplan-Meier method and Cox model analysis. Results There were 88 patients included in total, with mean NLR of 2.32 (range, 1.8-6.0). Histologic tumor grade and tumor stage were associated with the NLR significantly. The 10-year RFS rates were 98 and 81% for patients with an NLR less then 2.32 and patients with an NLR ≥ 2.32, respectively, the difference was significant (p = 0.010). The 10-year DSS rate was 97 and 81% for patients with an NLR less then 2.32 and patients with an NLR ≥ 2.32, respectively; the difference was not significant (p = 0.072). The independence of NLR in predicting the RFS was further confirmed in Cox model analysis. Conclusion The NLR significantly affects the prognosis in pediatrics with primary parotid MEC.

A novel surgical technique that disobliterates an occluded CCA was successfully performed in three cases. The detailed surgical steps are presented herein. After proximal division of the CCA behind the sternoclavicular junction, the occluded CCA was endarterectomized via antegrade ring stripping. After removal of the atheromatous core, the CCA was everted, and the wall remnants were cleaned under direct vision. Simultaneous eversion endarterectomy of the ICA was performed when necessary. After reversion of the CCA, it was transposed and anastomosed to the ipsilateral subclavian artery distal to the orifice of the vertebral artery. This novel technique can be used in selected cases by experienced surgeons.

However, its use may worsen kidney function in patients with renal insufficiency. Previous studies have demonstrated the safety and effectiveness of carbon dioxide (CO2)-EVAR. Here, we report cases of three male patients with mild renal insufficiency (mean age 79 years) that successfully underwent CO2-EVAR using INCRAFT ultra-low profile endografts. CO2 angiography provided the necessary vascular roadmap for safe and effective percutaneous EVAR, eliminating the need for iodinated contrast media and preventing contrast-induced nephropathy.

Increasing evidence suggests that the use of drug-coated balloons (DCBs) improves target lesion primary patency (TLPP) in dialysis access. However, few studies have investigated the use of DCBs specifically in central venous stenosis. Thus, this study presents our initial experience with DCBs in the central vein of a dialysis access circuit. Materials and Methods This is a retrospective cohort study of all hemodialysis patients who underwent central vein angioplasty with DCB between February 2017 and March 2018 at Singapore General Hospital. We compared the primary patency post DCB angioplasty to the primary patency of the patient’s previous plain old balloon angioplasty (POBA). Results We observed a 100% anatomic and procedural success rate with no complications. The median follow-up period was 151 days (interquartile range, 85.5-234 days) and no patients were lost to follow-up. The 30- and 90-day TLPPs after DCB were 93.3% and 75.7%, respectively. The mean primary patency in our study group post-DCB during the follow-up period was 164 days (vs. 140 days in the POBA group). However, no statistically significant difference was detected. Conclusion DCB showed a similar TLPP to that for POBA in treating central venous stenosis with a trend toward a longer re-intervention-free period for DCB. However, there were numerous confounding factors and a well-designed randomized controlled trial is warranted to assess the true utility of DCB in treating central venous stenosis.

Materials and Methods We retrospectively reviewed the medical records and computed tomography (CT) scans of 857 patients who underwent surgery for colorectal cancer between August 2009 and July 2012. Among these patients, 48 patients who were aged ≥60 years, underwent follow-up CT at least 5 years after surgery, did not have aortic disease, and did not receive radiation therapy were enrolled. The aortic tortuosity index (ATI) was defined by dividing the distance along the central lumen line from the lowest renal artery to the aortic bifurcation (L1) by the straight-line distance from the lowest renal artery to the aortic bifurcation (L2). Aortic diameters were measured at the lowest renal artery level (D1) and 20 mm below (D2). A paired t-test and Wilcoxon signed-rank test were used to compare lengths and diameters between the initial and final CT scan. Spearman’s correlation analysis was performed to determine the correlations between time and the changes in L1 and ATI. Results The average follow-up period was 68 months. The mean changes in L1 and L2 were 0.69 mm and -0.59 mm, respectively, while the mean changes in D1 and D2 were 0.77 mm and 0.58 mm, respectively. The mean increase in ATI was 0.015. All findings were statistically significant. On Spearman’s correlation analysis, ΔL1 and ΔATI showed no correlation with follow-up duration. Conclusion The infrarenal aortic length and tortuosity of elderly patients increases at a slow rate over time.

HC is known for its anti-leukemic, anti-oxidative, and anti-inflammatory properties. However, its anti-vascular endothelial aging efficacy and the underlying mechanisms are not fully understood. In this study, we investigated the anti-aging effects of HC in a high glucose (HG)-induced endothelial cell (EC)-aging model. Treatment with HC (40 μg/mL) increased migration of ECs, and increased phosphorylation of extracellular signal-regulated kinases and p38 in a dose-dependent manner. Following HG treatment (30 mM), HC significantly decreased the number of senescence-associated β-galactosidase positive cells, which are the biomarkers for aging, in a dose-dependent manner. Based on levels of phosphorylation, HC (40 μg/mL) was shown to increase expression of sirtuin1 (Sirt1) and endothelial nitric oxide synthase (eNOS) by 74.4% and 328.2%, respectively. Furthermore, treatment of HG-induced senescent ECs with HC (40 μg/mL) significantly increased nitric oxide production (P less then 0.05). These results demonstrate that HC both increases EC migration and regulates the Sirt1/eNOS pathway, suggesting HC has potential for protecting ECs against HG-induced aging.

Samples were obtained from two processing methods (method 1 entire fish adjuevan; method 2 both sides filleted adjuevan) with the fish species Galeoides decadactylus. Biogenic amines found in freshly produced adjuevan were histamine, putrescine, cadaverine, tyramine, β-phenyl ethylamine, and spermidine. Among these, the most prevalent were β-phenyl ethylamine and cadaverine. Biogenic amine contents varied according to the processing method but remained lower than levels considered hazardous for human health. The major fatty acids present in adjuevan from method 1 were docosahexaenoic acid, palmitic acid, and oleic acid. In adjuevan from method 2, the major fatty acids were oleic acid, stearic acid, and palmitic acid. The omega (w)-3/w-6 ratio was 8.87 and 4.12 for adjuevan from methods 1 and 2, respectively. Most of the fatty acids are considered healthy fats, making adjuevan a useful food for treating and preventing lifestyle diseases. The volatile compounds found composed of 19 aldehydes, 12 alcohols, 7 esters, 7 ketones, 3 furans, 10 aromatic compounds, and 7 acids with aldehyde, alcohol, and ester compounds as the predominant groups. Among the aldehydes, 2,4-heptadienal (E,Z), octanal, and 2-octenal (E) were most prevalent in adjuevan from method 1, whereas 2-nonenal (E), 2,4-heptadienal (E,Z), and octanal were most prevalent in adjuevan from method 2.

The purpose of this research was to study the activity of M. pruriens tempe peptides during the digestive process in vitro with pepsin-pancreatin, and absorption of peptides in the small intestine using the inverted intestinal sac method. Our results show that M. pruriens had the highest ACE-inhibiting activity after digestion in vitro after fermentation for 72 h (F72). F72 peptide absorption (%) and ACE-inhibitory activity of the absorbed peptides did not significantly differ between the different segments of the small intestine (duodenum, jejunum, and ileum). These results demonstrate that F72 tempe maintains ACE-inhibitory activity in each segment of the small intestine after both digestion and absorption.

For Umbelliferae plants extracts, the IC50 of DPPH radical (100 μM) quenching activities for extract, TPC, and TFC were 39∼179 μg dry weight (DW)/mL, 14.08∼38.11 μg TPC/mL, and 0.36∼1.51 μg TFC/mL, respectively. The oxygen radical absorbance capacity (ORAC) of extracts ranged from 11.44 to 42.88 mg Trolox equivalent (TE)/g DW extract, whereas ORAC for TPC and TFC was 47.40∼240.19 mg TE/g and 0.72∼11.22 g TE/g, respectively. The TPC had a superior linear correlation (r2=0.817) with 2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) values. Of the 14 Umbelliferae plant extracts, Sanicula rubiflora, Sanicula chinensis, Torilis japonica, Torilis scabra, and Angelica fallax showed the strongest antioxidant activity.

Outputs included total phenolic content (TPC), 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity (DPPH RSA), oxygen radical absorbance capacity (ORAC), total radical trapping antioxidant potential (TRAP), and comet assays. TPC was the highest in C3 (1,250.8 mg gallic acid equivalent/100 g). C1 exhibited a significantly higher DPPH RSA IC50 (7.5 mg/mL) and ORAC concentration (8.22 μM Trolox equivalent) compared with all other samples, and C1 and K1 exhibited the highest TRAPs. H2O2-induced DNA damage was effectively protected by Chunjang, with a higher observed in C2, C3, and K1 (24.2∼25.3 μg/mL) compared with the other samples (28.3∼30.0 μg/mL). Our results showed that commercial Chunjang contains polyphenol and antioxidant activities. The differences between the samples might be attributed to different origins, materials, and processing methods. Copyright © 2020 by The Korean Society of Food Science and Nutrition.

To confirm hydrolysis of the whey protein hydrolysates, the yield and α-amino acid content were determined. Since osteogenic cell activity is an important factor in osteogenesis, we evaluated the proliferation of osteogenic cells by measuring 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide and alkaline phosphatase (ALP) activity. To analyze bone matrix formation, we identified calcium deposition by staining with Alizaline red-S. The free amino acid content was significantly higher in the whey protein hydrolysates prepared using Protamex, Flavourzyme, and Alcalase than in the control. When cells were treated with 500 μg/mL of whey protein hydrolysates prepared using Protamex and Alcalase, cell proliferation increased by 120% and 130%, respectively, compared with the control group. In addition, ALP activity was significantly higher following treatment with 500 μg/mL of whey protein hydrolysates prepared using Protamex and Alcalase (142.61% and 135.06%, respectively; P less then 0.05). Furthermore, when treated with 125 μg/mL of the same hydrolysates, the rate of calcium deposition increased significantly to 157.56% compared with the control group (P less then 0.05). Therefore, our results suggest that whey protein hydrolysates prepared using Protamex and Alcalase may have more beneficial effects on osteoblast proliferation and bone health than those prepared using other proteolytic enzymes.

Berberry (Berberis vulgaris L., family Berberidaceae) is a plant that flourishes in Europe and Asia that has been largely investigated for its therapeutic effects. In the present study, we evaluated the protective effects of B. vulgaris on diazinon-induced brain damage in young male mice. Twenty-one young male albino mice weighing 18±2 g were divided in three equal groups of seven mice, and treated orally with either olive oil (control), diazinon 50 mg/kg+B. vulgaris extract 200 mg/kg, or diazinon 50 mg/kg. After three weeks, cerebrum and cerebellum samples were collected for antioxidant assays. The results indicated that diazinon increased oxidative stress in the brain of mice. The glutathione content and proceedings of antioxidant enzymes, such as glutathione peroxidase, superoxide dismutase, and catalase, were significantly reduced in both the cerebellum and cerebrum of diazinon-treated mice, compared with the control group. In addition, acetylcholinesterase (AChE) activity was inhibited by exposure to this pesticide. Administration of 200 mg/kg B. vulgaris extract with diazinon significantly decreased oxidative stress indices in all experiments. The results indicated that B. vulgaris extract has protective effects against lipid peroxidation of the cerebellum and cerebrum, and in regenerating AChE activity in the brain induced by diazinon.

The results showed that E. camaldulensis extracts are rich in phytochemicals, including flavonoids, phenols, saponin, terpenes, and tannin. Four days after infection with malaria, elevated parasitemia levels in untreated control mice dropped by 4.57%. Administration of E. camaldulensis extracts at doses of 100, 200, and 300 mg/kg significantly decreased parasitemia levels by 17.39, 61.88, and 60.53%, respectively (all P less then 0.05), relative to untreated control mice; however, standard antimalarial drugs were more efficacious and reduced parasitemia by 86.73%. Treatment with both E. camaldulensis extracts (100∼300 mg/kg) and standard antimalarial drugs significantly decreased malarial-induced physiological imbalances in liver and renal biomarkers, and serum electrolytes in malaria-infected mice compared with controls (P less then 0.05). The therapeutic effect of E. camaldulensis was greatest at a dose of 200 and 300 mg/kg. These findings indicate that E. camaldulensis aqueous leaf extracts could protect against malarial-induced aberrations in liver and renal function whilst exhibiting anti-malarial effects, and could explain its use as an antimalarial remedy in traditional medicine.

However, pollen is difficult to absorb because of its hard form. This study explores the use of the acid-treated acorn pollen (acorn pollen deposited in apple vinegar for 30 days). The health functions of acid-treated acorn pollen on post-menopausal metabolism was tested by analyzing in vitro and in vivo biomarkers for glucose metabolism, by using the acid-treated acorn pollen and its residues, respectively. In vitro experiments showed high activity after measuring the low potency of glucose-related enzymes. In vivo experiments showed reduced blood glucose and insulin levels after consuming pollen. Pollen also increased the concentration of glucokinase, a glucose-regulating enzyme in hepatic and nephritic tissue, and lowered the concentration of glucose-6-phosphatase. These results are encouraging in showing that acid pollen can be used as a functional health food for treatment of post-menopausal metabolism.

Three-month-old C57BL/6 female mice (n=46) were sham-operated (SHAM) or OVX and randomly assigned to the control or WM diets for 12 weeks SHAM-control, OVX-control, OVX+1%, or 10% (wt/wt) freeze-dried WM. All diets were isocaloric and isonitrogenous, and had the same calcium and phosphorus concentrations. Freeze-dried WM supplementation was not able to prevent the decrease in whole body, tibial, and lumbar bone mineral density due to estrogen deficiency. Micro-computed tomography analyses showed that WM was also not able to modulate changes in tibial trabecular and cortical bone microarchitecture due to ovariectomy. However, the lumbar trabecular micro-architecture analyses revealed that the WM-10% group had a similar connectivity density, trabecular number, trabecular separation, and structure model index as the SHAM group. Supplementation with 10% WM reduced plasma cholesterol and total liver lipids to the level of the SHAM group but was still similar to that of the OVX-control group. Supplementation with 10% WM increased liver catalase (CAT) mRNA levels but had no effects on mRNA levels of glutathione peroxidase (GPX) and the pro-inflammatory cytokine interleukin-6. There were no differences in plasma activity of the antioxidant enzymes GPX and CAT between all treatment groups. Our findings demonstrate some positive effects of watermelon for modulating lipids and attenuating lumbar vertebral bone loss arising from ovarian hormone deficiency.

Mice feeding FCCE exhibited reduced body weight gain compared to those in the HFD-fed group, and showed lower abdominal fat pad weight including epididymal, retroperitoneal, and mesenteric adipose tissue. Further, FCCE administration decreased adipocyte size by suppressing adipogenic factors such as peroxisome proliferator activated receptor γ and CCAAT/ enhancer-binding protein α, and lipogenic factors such as sterol regulatory element-binding protein-1c, fatty acid synthase, and stearoyl CoA desaturase-1. Moreover, FCCE decreased levels of lipids in serum and liver as well as serum alanine aminotransferase and aspartate aminotransferase levels, markers of liver injury. Histological observations of the liver showed that FCCE significantly attenuated HFD-induced hepatic steatosis. The effect of FCCE on hepatic lipid regulatory factors may be partly associated with adenosine monophosphate-activated protein kinase activation. These results suggest that gallic acid-enriched FCCE has potential to be a promising functional food for prevention of obesity and obesity-related fatty liver disease.

Systolic blood pressure (SBP), total cholesterol, triglyceride, and glucose levels, as well as oxidative damage and antioxidant activity in the plasma and kidney, were evaluated in four experimental groups control Wistar rats (W-C) and SHR-C that received water, and Wistar rats and SHR treated with ACH09 (200 mg/kg/d) in drinking water for 12 weeks (W-ACH09 and SHR-ACH09, respectively). SBP increased in the SHR group compared with the W groups and the treatment with ACH09 prevented the development of hypertension. Plasma triglyceride and total cholesterol levels increased in SHR compared with W-C rats; these changes prevented by treatment with ACH09. Glucose levels did not differ between the groups. The SHR group had increased oxidative damage in plasma, as expressed by 2-thiobarbituric acid reactive substances (TBARS) levels, and this prevented by ACH09. Levels of TBARS in the kidneys were lower in the SHR-ACH09 group than in the SHR-C group. Further, ACH09 increased the superoxide dismutase activity in both the plasma and kidneys of both SHR and Wistar rats. These results suggest that ACH09 is protective against disruption of blood pressures, oxidant status, and lipid profile in SHR, and provide important evidence on the benefits of ACH09 on hypertension and associated cardiovascular complications.

Medical nutrition therapy has been identified as a major therapeutic support for diabetic patients, while preventive strategies in prediabetic or high-risk individuals have mainly focused on supplementation with bioactive compounds. Recently, meal-based interventions have been investigated as novel and safe long-term strategies for improving glucose regulation. However, evaluation of meal-based interventions is difficult since it requires analysis of sensitive markers. Biomarkers can also be used to identify individuals at risk for diabetes, which is important for disease prevention. In this review, we summarize current evidence from meal-based intervention studies conducted with the aim of improving glucose homeostasis in individuals at risk of diabetes using clinical biomarkers currently used to assess diabetic risk. Very low-calorie diets have significantly improved glucose regulation in obese adults and in adults with type 2 diabetes mellitus. In particular, changing the ratios of macronutrients through calorie restriction reduces fasting glucose level and hemoglobin A1c levels in patients with diabetes mellitus. However, this effect is limited in both obese and healthy adults. To date, multiple glucose-related markers have been identified as clinical biomarkers of diabetes. Additional clinical biomarkers include cholesterol levels, hematological markers, and inflammatory markers. Taken together, the evidence presented in this review may help for selection of clinical biomarkers for meal-based preventive approaches for non- or pre-diabetic individuals to prevent onset of diabetes.

We carried out a systematic review and meta-analysis of randomized controlled trials (RCTs) to assess the effect of vitamin C and E co-supplementation on CRP. A systematic search was carried out using PubMed, Scopus, Ovid, Cochrane, Embase, and the Web of Science without any language or time restriction (until 31 March 2019) to retrieve RCTs that examined the effect of vitamin C and E co-supplementation on CRP. A meta-analysis was carried out using a random effects model, and I2 indexes were used to evaluate the heterogeneity. The search yielded 5,134 publications, including 8 eligible RCTs. The results indicate that vitamin C and E co-supplementation does not significantly impact levels of serum CRP [weighted mean difference and 95% confidence interval with random effects model analysis -0.22 mg/L (-0.85, 0.41), P=0.5]. Subgroup analysis demonstrated that vitamin C and E co-supplementation significantly reduced serum CRP in participants ≥30 years of age, but significantly increased serum CRP in participants less then 30 years of age. The results of this meta-analysis indicate beneficial effects of vitamins C and E co-supplementation on CRP in participants ≥30 years of age, and not in younger participants. To confirm these results, further well-designed RCTs are needed. Copyright © 2020 by The Korean Society of Food Science and Nutrition.

A Poisson sampling distribution model was used to quantify the health risk, in which the coefficient of exposure-response was derived from a simple Meta-analysis. The result shows that the old people are the most vulnerable population while exposing to PM2.5, for which they are advised to reduce intensity of their physical activities. It is expected that this study is insightful to create a nexus between air quality information and public communication, which help publics take appropriate actions on health protection.

We aimed to detect the situation of intestinal parasitic infections in the Farashband district in Fars Province South of Iran and identify influential factors in the escalation of parasitic diseases and to reduce them. Methods Overall, 1009 participants from the age of 6 months to 90 years were selected from 3 cities and 15 villages of Farashband district, Fars Province South of Iran from 2015 to 2016. Parasitological methods such as the direct assay method, formalin-ether concentration method, and zinc sulfate flotation were used for diagnosis of worm eggs, cysts, and protozoa trophozoite. Susceptible and protozoan positive samples were stained using the Trichrome staining method. The modified acid-fast staining procedure was conducted for diarrheal samples and the results were used for diagnosis of coccidia. Results Overall, 313 subjects were infected with at least one intestinal parasite (pathogenic and nonpathogenic). Helminthes infection and protozoan infection were observed in 9 (0.9%) and 304 (30.13%) participants, respectively. Fecal samples of 34 patients with diarrheal feces were used to prepare smears for further examinations using the Ziehl-Neelsen staining method. Examinations showed no infection with coccidia. Conclusion Helminthes infection has decreased drastically but protozoan infection is still considered a health issue in this region. It is possible to reduce parasitic infections through proper measures such as increasing public awareness and education the public, especially children on health problems with education courses.

Therefore, we aimed to ascertain effects of income inequality measured by Gini-coefficient to death from suicide in Iran. Methods This is an ecological study on the relation of Gini-coefficient and suicide death in Iran. Data were obtained from Iranian Urban and Rural Household Income for Gini-coefficient and Expenditure Survey and Iranian Forensic Medicine Organization for suicide. Concentration Index was used to determine of inequality by Gini-coefficient in suicide death and prediction model was applied by Stata software. Significant level considered less than 5%. Results A Gini-coefficient between 0.2523 and 0.3755 (mean, 0.3092) was observed. The overall concentration index CI was -0.10 (95% CI= -0.19 to -0.01), therefore our results confirmed a positive inequality in incidence suicide rate result from income inequality in Iran. Conclusion Our results showed a positive inequality due to Gini-coefficients in suicide death. This study could be a start for investigation of inequality source in geographical units and at the individual level in all provinces.

Available information about Iranian bodily dimensions is not applicable to the general population due to the sample of people investigated. This study aimed to present the first Iranian anthropometric databank by estimation. Methods After a systematic review, 24 relevant sources of information were found and included. No time limit was considered. The method of Rapid Anthropometrics Scaled for Height was used. Results Overall, 36 bodily dimensions were estimated, for which the seven percentiles of 1st, 5th, 25th, 50th, 75th, 95th, and 99th were calculated, stratified by sex. Conclusion The resulting tables can be claimed as the most representative anthropometric databank for Iranian general 20-64 yr population now. Data are suitable for practical purpose and are applicable in both occupational and community setting.

Serum zinc concentration is the most widely used indicator of zinc status for general populations. Considering the limited data available on seasonal fluctuation of serum zinc concentration, we aimed at determining seasonal variations in serum zinc concentrations of Tehranian adults. Methods The current study was conducted within the framework of the Tehran Lipid and Glucose Study, on 4698 subjects, aged ≥20 years. Serum zinc samples of subjects were obtained from all four seasons over three years (from 2009 to 2011); samples of similar seasons over three years were placed in one group and the geometric means of serum zinc concentration of four seasons were compared to determine possible seasonal variations. Results Participants with mean age 46.3 yr and geometric mean of serum zinc concentration 116.3 μg/dl, were studied for almost three years through four seasons. Serum zinc concentrations in spring and summer were significantly higher than those in autumn and winter (112.2 and 114.4 vs. 106.7 and 104.8 μg/dl; P less then 0.001, respectively). Moreover, monthly serum zinc concentration of all subjects differed, with the lowest and highest levels found in October and August (98.5 vs. 122.7; P less then 0.001). Conclusion This study demonstrates the difference in serum zinc concentration in Iranian adults of both genders in different months and seasons during the year.

One of the first steps towards reduction of neonatal mortality is to identify its determinants using health production function. The aim of the present study was to estimate neonatal health production function for Iran. Methods In this cross-sectional study, Iranian Multiple Indicator Demographic and Health Survey (Ir-MIDHS) 2010 was used. Four categories of socioeconomic, mother, neonatal demographic and healthcare system factors were entered into the Binomial Logistic Regression model to estimate neonate health production function. Households’ economic status was constructed using principal component analysis. Results History of abortion/stillbirth had the highest significant positive impact on odds of neonatal mortality (odds ratio=1.98; 95 % CI=1.55-2.75), indicating that neonates of mothers with such a history had 1.98 times higher chance of death compared to other neonates. Moreover, odds ratio of neonatal death for the poorest quintiles was 1.70 (95 % CI=1.08-2.74), indicating that by moving from the poorest quintile to the richest one, the odds of being alive for neonates increased up to 70%. However, skilled birth attendant decreased the chance of death up to 58% (odds ratio=0.58; 95 % CI=0.36-0.93). Conclusion Considering the most significant inputs of neonatal health production function in Iran, improvement of economic status of households, provision of appropriate care services for mothers, and improvement of delivery care provided by trained personnel, could be priorities for health policymakers to act and reduce neonatal mortality in Iran.

Methods After linguistic validation, the Iranian version of social well-being scale was completed by 715 participants, aged ≥18 yr between Jan and Sep 2015. Concurrent validity was examined by calculating the Pearson’s correlation coefficient between the dimensions of social well-being and social support. Internal consistency, Cronbach’s alpha coefficient, confirmatory and explanatory factor analyses were also examined. Results The internal consistency as measured by Cronbach’s alpha coefficients was 0.72 for total score. No ceiling and floor effect was found in total score or any of the subscales. The concurrent correlation coefficients between social well-being and social support ranged from good to excellent agreement. Exploratory factor analysis supported mainly comparable results with the original US English dialect version. The results of the confirmatory factor analysis for 5-factor models indicated acceptable fit for the proposed research models. Conclusion The findings support the initial reliability and validity of the Iranian version of the social well-being scale in the research and community settings in Iran.

We aimed to investigate the epidemiology of suicide and some associated individual, family, and social factors. Methods A historical cohort study was conducted among all cases (748 persons) reports related to suicide/suicide attempt that register in hospital reporting system and health care center in Gonabad and Bajestan, Iran, from 2009 to 2014. The required data were extracted through a checklist. Descriptive (mean and standard deviation) and analytic statistics (t-test, Chi-square, and logistic regression) applied to analyzed data. All data were analyzed using SPSS software. Results Of the 748 reported suicide attempters, 17 cases (2.3%) had completed suicide. The annual average incidence rate of suicide was 110.03 per 100,000 populations. The mean age of suicide attempt had significantly decreased during the time (P=0.007). Furthermore, a significant association was observed between outcome of suicide and place of residence (P=0.019), history of physical illnesses (P=0.002), and method of suicide (P=0.001). Conclusion Due to trend of age among suicide attempters, considering intervention programs of suicide prevention for school pupils and university students especially individuals residing in rural areas, as well as individuals suffering from physical illness would be effective to reduce the rate of suicide.

Methods A retrospective analysis of clinical data of 120 thyroid cancer patients admitted to Jiangxi Provincial People’s Hospital Affiliated to Nanchang University, Nanchang, China from February 2014 to February 2017 was performed. According to different treatment methods, they were divided into observation group of 62 cases and control group of 58 cases. Both groups were treated with total thyroidectomy. The control group was treated with anti-infection and prevention of complications after operation, the observation group with radioactive iodine therapy. Treatment efficacy, quality of life score, recurrent laryngeal nerve injury and postoperative survival rate were compared between the two groups. Results The total effective rate of treatment in the test group was 98.39%, significantly higher than 72.41% in the control group, with a statistically significant difference (P less then 0.05). Compared with the control group, the fatigue score of the test group was lower, but the score in the area of emotion function and the overall health status score were higher, with a statistically significant difference (P less then 0.05). There was no significant difference in the recurrent laryngeal nerve injury between the two groups of patients. The postoperative survival rate of the test group of patients was 96.77%, significantly higher than 86.21% of the control group. Conclusion The effect of radioactive iodine therapy after total thyroidectomy is remarkable, which can significantly improve the clinical treatment efficacy and postoperative quality of life of patients, worthy of clinical application.

We evaluated its effects on the management efficiency, quality control, and operating costs of medical consumables (MCs) in the clinical nursing surroundings in a single Chinese hospital-Anhui Provincial Hospital from 2014 to 2015. Methods Amount-based packages (ABP) and procedure-based packages (PBP) models were created. They were introduced the use of quick response (QR) code scanning for using in clinical nursing departments (CNDs). Questionnaires were prepared by referring to previous literature and using Delphi method repeatedly, further discussed and formalized. Partial results of the formal questionnaire were analyzed using SPSS. Results Frequency of MCs claims reduced without any requirements of MCs in 70% of CNDs. Average time spent on the inventory per week decreased and the time required to procure MCs reduced. Moreover, the average satisfaction score with MCs management increased, reaching 100%. Average space occupied by MCs decreased significantly, reducing by 1.2444m3. Overall, 100% of the respondents concluded that the management of MCs improved effectively and the inventory turnover rate had accelerated. The cost of MCs decreased by 15% with more than 10% increase in in-hospital amount, and the average daily cost of MCs also showed decrease. Conclusion SPD can improve the efficiency of MCs management in CNDs, reducing medical risks and disputes, saving hospital operating costs, and decreasing capital occupation.
