Liu X. Association between dietary inflammation index with anemia in Americans: a cross-sectional study with U.S. National health and nutrition examination survey. Hematology 2024; 29:2337567. [PMID: 38573235 DOI: 10.1080/16078454.2024.2337567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Accepted: 03/27/2024] [Indexed: 04/05/2024] Open
Abstract
OBJECTIVES Dietary inflammatory index (DII) is utilized to determine the inflammatory effects of nutrients and foods on various diseases. Inflammation is a potential risk factor for anemia. We hypothesize that pro-inflammatory diets boost the incidence of anemia, as indicated by high DII. METHODS 41, 360 Americans were included in this study from the U.S. National Health and Nutrition Survey (NHANES) from 2003-2018. Multivariable logistic regression models were employed to examine the association between DII and anemia. RESULTS After adjustment for all the covariates, the odds ratios (ORs) (95% CI) between the risk of anemia and DII across tertile 3 were 1.2556 (95% CI 1.0621, 1.4843; P = 0.0077), and the trend test was statistically significant (P for trend = 0.009). Furthermore, in the subgroup analysis stratified by gender. The ORs (95% CI) between the risk of anemia and DII across tertile 2 and 3 were 1.8071 (95% CI 1.1754, 2.7783; P = 0.0070) and 2.1591 (95% CI 1.4009, 3.3278; P = 0.0005) in men after multivariable adjustment. However, in women, this association was only significantly different (P < 0.05) across tertile 3 in the crude model. In the subgroup analysis stratified by race, this association was significant (P < 0.05) between the risk of anemia and DII for Non-Hispanic Whites/Blacks after adjustment. DISCUSSION Together, anemia was significantly associated with DII using logistic regression. In stratified analyses, higher DII scores were linked to an increased incidence of anemia in men, while no association was found in women after adjustment. Additionally, anemia may be associated with greater pro-inflammatory diets in Non-Hispanic Whites/Blacks. CONCLUSION In the present study, we evaluate the potential relationship between DII and anemia using data from NHANES. This cross-sectional study confirmed the hypothesis that the higher DII was significantly associated with a higher risk of anemia in the U.S. population.

Comparison of the components of fresh Panax notoginseng processed by different methods and their anti-anemia effects on cyclophosphamide-treated mice. JOURNAL OF ETHNOPHARMACOLOGY 2024; 330:118148. [PMID: 38583734 DOI: 10.1016/j.jep.2024.118148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 04/01/2024] [Accepted: 04/02/2024] [Indexed: 04/09/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The traditional Chinese herb Panax notoginseng (PN) tonifies blood, and its main active ingredient is saponin. PN is processed by different methods, resulting in different compositions and effects. AIM OF THE STUDY To investigate changes in the microstructure and composition of fresh PN processed by different techniques and the anti-anemia effects on tumor-bearing BALB/c mice after chemotherapy with cyclophosphamide (CTX). MATERIALS AND METHODS Fresh PN was processed by hot-air drying (raw PN, RPN), steamed at 120 °C for 5 h (steamed PN, SPN), or fried at 130 °C, 160 °C, or 200 °C for 8 min (fried PN, FPN1, FPN2, or FPN3, respectively); then, the microstructures were compared with 3D optical microscopy, quasi-targeted metabolites were detected by liquid chromatography tandem mass spectrometry (LC‒MS/MS), and saponins were detected by high-performance liquid chromatography (HPLC). An anemic mouse model was established by subcutaneous H22 cell injection and treatment with CTX. The antianemia effects of PN after processing via three methods were investigated by measuring peripheral blood parameters, performing HE staining and measuring cell proliferation via immunofluorescence. RESULTS 3D optical profiling revealed that the surface roughness of the SPN and FPN was greater than that of the other materials. Quasi-targeted metabolomics revealed that SPN and FPN had more differentially abundant metabolites whose abundance increased, while SPN had greater amounts of terpenoids and flavones. Analysis of the composition and content of the targeted saponins revealed that the contents of rare saponins (ginsenoside Rh1, 20(S)-Rg3, 20(R)-Rg3, Rh4, Rk3, Rg5) were greater in the SPN. In animal experiments, the RBC, WBC, HGB and HCT levels in peripheral blood were increased by SPN and FPN. HE staining and immunofluorescence showed that H-SPN and M-FPN promoted bone marrow and spleen cell proliferation. CONCLUSION The microstructure and components of fresh PN differed after processing via different methods. SPN and FPN ameliorated CTX-induced anemia in mice, but the effects of PN processed by these two methods did not differ.

Associations of dietary, sociodemographic, and anthropometric factors with anemia among the Zhuang ethnic adults: a cross-sectional study in Guangxi Zhuang Autonomous Region, China. BMC Public Health 2023; 23:1934. [PMID: 37803356 PMCID: PMC10557179 DOI: 10.1186/s12889-023-16697-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2022] [Accepted: 09/04/2023] [Indexed: 10/08/2023] Open
Abstract
BACKGROUND After decades of rapid economic development, anemia remains a significant public health challenge globally. This study aimed to estimate the associations of sociodemographic, dietary, and body composition factors with anemia among the Zhuang in Guangxi Zhuang Autonomous Region, China. METHODS Our study population from the baseline survey of the Guangxi ethnic minority Cohort Study of Chronic Diseases consisted of 13,465 adults (6,779 women and 6,686 men) aged 24-82 years. A validated interviewer-administered laptop-based questionnaire system was used to collect information on participants' sociodemographic, lifestyle, and dietary factors. Each participant underwent a physical examination, and hematological indices were measured. Least absolute shrinkage and selection operator (LASSO) regression was used to select the variables, and logistic regression was applied to estimate the associations of independent risk factors with anemia. RESULTS The overall prevalences of anemia in men and women were 9.63% (95% CI: 8.94-10.36%) and 18.33% (95% CI: 17.42─19.28%), respectively. LASSO and logistic regression analyses showed that age was positively associated with anemia for both women and men. For diet in women, red meat consumption for 5-7 days/week (OR = 0.79, 95% CI: 0.65-0.98, p = 0.0290) and corn/sweet potato consumption for 5-7 days/week (OR = 0.73, 95% CI: 0.55-0.96, p = 0.0281) were negatively associated with anemia. For men, fruit consumption for 5-7 days/week (OR = 0.75, 95% CI: 0.60-0.94, p = 0.0130) and corn/sweet potato consumption for 5-7 days/week (OR = 0.66, 95% CI: 0.46-0.91, p = 0.0136) were negatively correlated with anemia. Compared with a normal body water percentage (55-65%), a body water percentage below normal (< 55%) was negatively related to anemia (OR = 0.68, 95% CI: 0.53-0.86, p = 0.0014). Conversely, a body water percentage above normal (> 65%) was positively correlated with anemia in men (OR = 1.73, 95% CI: 1.38-2.17, p < 0.0001). CONCLUSIONS Anemia remains a moderate public health problem for premenopausal women and the elderly population in the Guangxi Zhuang minority region. The prevention of anemia at the population level requires multifaceted intervention measures according to sex and age, with a focus on dietary factors and the control of body composition.

Abstract
Anemia is a worldwide public health problem that is worst in low- and middle-income countries (LMICs), reaching 60% of prevalence. The etiology of anemia is diverse and multifactorial, with iron deficiency being the most prevalent, and often found in pregnant women. Iron is indispensable for the production of red blood cells and approximately 80% of the available heme iron is used for hemoglobin synthesis in mature erythroblasts. Iron deficiency affects oxygen transport, compromising energy and muscle metabolism and can occur with depletion of iron storage, defective erythropoiesis, and low hemoglobin levels. We analyzed anemia prevalence in pregnant women from 2000 to 2019 worldwide correlating them with current (2022) country income, with especial attention to LMICs using WHO dataset. Our analysis indicates that pregnant women from LMICs had a higher probability (40%) of anemia during pregnancy especially those from Africa and South Asia. Africa and the Americas showed a higher decrease in the prevalence of anemia from 2000 to 2019. The Americas and Europe have a lower prevalence, concentrated in 57% of most upper-middle- and high-income countries. Black women are also more prone to develop anemia during pregnancy, especially if they are from LMICs. However, the prevalence of anemia appears to decrease with an increase in educational level. In conclusion, anemia prevalence fluctuated from 5.2 to 65.7% worldwide in 2019, validating it as a public health problem.

Abstract
OBJECTIVE The goal of this study was to evaluate the possible associations between anemia and morphologic features of lumbar disc degeneration (LDD) in subjects with low back pain. MATERIALS AND METHODS A total of 131 patients with normocytic or microcytic anemia (mean age 41.0 ± 6.4 yrs, BMI: 24.8 ± 3.3 kg/m2, 12.2% men) and a matched control group of 131 patients without anemia (mean age 41.0 ± 6.4 yrs, BMI: 24.9 ± 3.1 kg/m2, 12.2% men) were evaluated for LDD according to the Pfirrmann scoring system. The primary outcome was the difference of radiological features of LDD between two groups. The second outcome was the correlation between the hemoglobin (Hb) value and disc degeneration (DD). Statistical associations were assessed by Student's t-test, Chi-square test, and Spearman correlation. RESULTS Anemic patients had a significantly higher number of degenerated discs than non-anemic patients in the level of L2/3 and L3/4 (p < 0.05). We also found that the severe DD occurred more frequently in the level of L2/3, L3/4 and L5/S1 among anemic patients (p < 0.05). In addition, we noticed that the incidence of multilevel LDD happened much more frequently in patients with anemia (p < 0.05). The Hb value showed a borderline negative correlation with the total score of DD (p = 0.056). CONCLUSION The results suggested that patients with anemia, and those without are radiologically different with varying patterns of DD. Patients with back pain and anemia were more likely to have extensive and severe DD. Although relevant mechanisms are not yet well understood, this study improved our understandings of the pathophysiology for LDD.

Abstract
The burden of extrapulmonary tuberculosis (EPTB) has gradually increased in recent years, but not enough epidemiological data is available from central Guangxi. To better understand the epidemiology of EPTB in central Guangxi and identify risk factors associated with them, we retrospectively investigated the epidemiology of tuberculosis (TB), especially EPTB, among patients admitted to the Chest Hospital of Guangxi Zhuang Autonomous Region between 2016 and 2021. We excluded those infected with both pulmonary tuberculosis (PTB) and EPTB, reported the proportion and incidence of PTB or EPTB, and compared the demographic characteristics and risk factors of EPTB and PTB cases using univariate and multivariate logistic regression models. Among 30,893 TB patients, 67.25% (20,774) had PTB and 32.75% (10,119) had EPTB. Among EPTB, pleural, skeletal, lymphatic, pericardial, meningeal, genitourinary, intestinal, and peritoneal TB accounted for 49.44%, 27.20%, 8.55%, 4.39%, 3.36%, 1.48%, 0.87%, and 0.79%, respectively. Patients who were younger (age < 25), from rural areas, Zhuang and other ethnic groups, and diagnosed with anemia and HIV infection were more likely to develop EPTB. However, patients with diabetes and COPD were less likely to have EPTB. From 2016 to 2021, the proportion of PTB cases decreased from 69.73 to 64.07%. The percentage of EPTB cases increased from 30.27 to 35.93%, with the largest increase in skeletal TB from 21.48 to 34.13%. The epidemiology and risk factors of EPTB in central Guangxi are different from those of PTB. The incidence of EPTB is increasing and further studies are needed to determine the reasons for it.

Abstract
Background: It is known that oral diseases such as periodontal (gum) disease are closely linked to various systemic diseases and disorders. Deep learning advances have the potential to make major contributions to healthcare, particularly in the domains that rely on medical imaging. Incorporating non-imaging information based on clinical and laboratory data may allow clinicians to make more comprehensive and accurate decisions. Methods: Here, we developed a multimodal deep learning method to predict systemic diseases and disorders from oral health conditions. A dual-loss autoencoder was used in the first phase to extract periodontal disease-related features from 1188 panoramic radiographs. Then, in the second phase, we fused the image features with the demographic data and clinical information taken from electronic health records (EHR) to predict systemic diseases. We used receiver operation characteristics (ROC) and accuracy to evaluate our model. The model was further validated by an unseen test dataset. Findings: According to our findings, the top three most accurately predicted chapters, in order, are the Chapters III, VI and IX. The results indicated that the proposed model could predict systemic diseases belonging to Chapters III, VI and IX, with AUC values of 0.92 (95% CI, 0.90-94), 0.87 (95% CI, 0.84-89) and 0.78 (95% CI, 0.75-81), respectively. To assess the robustness of the models, we performed the evaluation on the unseen test dataset for these chapters and the results showed an accuracy of 0.88, 0.82 and 0.72 for Chapters III, VI and IX, respectively. Interpretation: The present study shows that the combination of panoramic radiograph and clinical oral features could be considered to train a fusion deep learning model for predicting systemic diseases and disorders.

Abstract
Maternal infections, nutrient deficiencies, and inflammation (MINDI) co-exist in lactating indigenous women in Panama, but their impact on maternal iron status and infant growth is unknown. For this secondary analysis of cross-sectional data of lactating mothers from our MINDI cohort, we investigated associations of MINDI variables with maternal anemia, elevated serum transferrin receptor (sTfR), low serum iron, hepcidin, ferritin, and infant weight-for-age (WAZ), length-for-age (LAZ), and head-circumference-for-age (HCAZ) Z-scores in 99 mother-infant dyads. A bootstrapping resampling procedure preselected covariates for inclusion in multivariable regressions models from chronic maternal infections and nutritional status [folate, vitamins A, D, retinol-binding protein (RBP), insulin-growth factor-1 (IGF-1)] and inflammation [C-reactive protein (CRP), cytokines, platelet indices] indicators. Anemia was prevalent (53.5%) but underestimated due to widespread low plasma volume (<2.2 L, 79.9%) and was associated with indicators of malnutrition [lower IGF-1, body mass index (BMI), vitamin D, and intake of green/leafy vegetables], but not inflammation. Higher CRP was associated with lower serum iron, and higher hepcidin and ferritin, whereas maternal platelets were associated with lower HCAZ (β = −0.22), WAZ (β = −0.17), and LAZ (β = −0.17). Higher LAZ was also associated with maternal serum vitamin D (β = 0.23), whereas maternal iron supplementation lowered LAZ (β = −0.22). Assessment of iron status in this MINDI cohort is complex and supplementation strategies must consider consequences for both the mother and the infant.

Abstract
PURPOSE It has not been determined which factors were related to multilevel lumbar disc degeneration (MLDD). The objective of this study was to determine the prevalence of MLDD among symptomatic patients using the magnetic resonance imaging method. The study also aimed to clarify the associations between MLDD and suspected risk factors through a multivariate model. METHODS A total of 530 young and middle-aged patients, suffered from low back pain were retrospectively assessed by 2 independent observers, who used sagittal T2-weighted MR imaging. Subjects were divided into two groups, MLDD group and non-MLDD group, according to the number of degenerated discs. Demographic and radiological data included age, gender, weight, height, body mass index, smoking status, alcohol drinking, lumbar lordosis, presence of hypertension (HT), diabetes mellitus and anemia. RESULTS There were 309 men and 221 women with an average age of 37.5 ± 8.5 years. In general, 37.7% of patients were diagnosed with disc degeneration (DD) at more than two levels. Triple level DD was the most common pattern and was more prevalent in women (p <0.05). Using multivariate analyses, age (odds ratio [OR]: 1.14; 95% confidence interval [CI] 1.11-1.18; p <0.001), hypertension (OR: 2.67; 95% CI 1.38-5.16; p = 0.03) and anemia (OR: 3.84; 95% CI 2.03-7.28; p <0.001) were significantly associated with MLDD. CONCLUSION Despite the young age of this cohort, MLDD is common among patients with low back pain. A significant independent association exists between age, HT, anemia and multilevel disc degeneration in the lumbar region.

Effects of a locally available dietary interventions counselling on the community-based management of anaemia in children under five years in Ghana: Kumbungu cluster randomized controlled trial protocol. PLoS One 2022; 17:e0266157. [PMID: 35446902 PMCID: PMC9022816 DOI: 10.1371/journal.pone.0266157] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Accepted: 02/28/2022] [Indexed: 11/23/2022] Open
Abstract
Anaemia in children under five years remains a significant cause of mortality and morbidity in low-middle income countries. Globally, 27% of the world’s population is anaemic, of which developing countries account for more than 89%. The global prevalence is worse in Africa and Asia. Anaemia has the potential of maintaining the cycle of poverty, as it prevents children from attaining their full development potential. An important part of anaemia in children under-five years are preventable. Locally available dietary (LAD) interventions may be the sustainable interventions to address the high prevalence of anaemia in our communities. The aim of the study is to determine the effect of counselling on Locally Available Diet, on anaemia among children aged 6–59 months in the Kumbungu District of the Northern Region, Ghana. This study will be a community-based cluster randomized, controlled trial, with two parallel arms; Iron + Folic Acid (IFA arm) hereby referred to as the Standard care arm and Iron + Folic Acid + Counselling on Locally available dietary intervention (IFA+LAD arm) referred to as the Standard Plus arm. Study participants are children between the ages of 6 to 56 months. All study participants would receive iron plus folic acid. The minimum number of children per arm is 330 and the number of community clusters is 10 (5 per study arm). Also, considering this study proposes two parallel arms, the total minimum study sample size of children under five years is 496, the minimum total number of community clusters is 10 and a minimum of 25 households per community cluster, 124 households per study arm and 248 households for the study. Randomization is at the level of the clusters (selected communities). The intervention group receives counselling on LAD at a household level aimed at promoting the intake of locally available iron, folate and vitamin B12 rich foods. Also encourage the intake of food rich in enhancers of iron absorption and discouraging the intake of food rich in inhibitors of iron absorption. The primary outcome is mean haemoglobin levels in study arms. Secondary outcomes would include measurement of weight, height/length, mid upper arm circumference, dietary record, serum iron, ferritin, and other parameters of full blood count. Ethical clearance has been obtained and trial registered with Pan African Trial Registry (www.pactr.org) PACTR201906918438423.

Abstract
CONTEXT Sheng Xue Fang (SXF) has been used to treat anaemia for decades with good efficacy. OBJECTIVE To study the effect and possible mechanism of SXF to restore haematopoietic function. MATERIALS AND METHODS Balb/c mice (10 per/group, half male, half female) were treated with SXF (three dose groups, 8.5, 17, and 22.1 g/kg) by gavage for 14 days, and cyclophosphamide (80 mg/kg) was injected on days 10-12. Only injection of cyclophosphamide (negative control) or physiological saline (blank control) were included as controls. The spleen and femur were processed for histopathology. Active components and the target of SXF were screened. The target was used for gene enrichment and protein-protein interaction (PPI) analysis. RESULTS Red blood cell relative changes in the SXF group (low: -5.50 ± 1.58%; medium: -11.11 ± 4.15%; high: -8.81 ± 2.67%) and relative negative control (26.21 ± 2.51%) significantly increased (all p < 0.01) in female mice. Haemoglobin and red blood cell-specific volume showed the same trend. However, SXF did not have significant effects on male mice. Splenic index in the medium group (4.44 ± 0.46%) relative negative control (3.38 ± 0.10%) significantly improved (p < 0.01) in female mice. Using network pharmacology, 77 active components and 337 targets were screened from SXF. These targets are closely related to the mitogen-activated protein kinase pathway. CONCLUSIONS SXF has good clinical application potential. However, the mechanism requires in-depth research. Our findings are of great significance in anaemia treatment and provide a new perspective for Chinese medicine research.

[PMID: 34585127 PMCID: PMC8455640 DOI: 10.1016/j.eclinm.2021.101136] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 08/29/2021] [Accepted: 09/03/2021] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND Anemia remains a major public health issue, particularly for children and women in low- and middle-income countries (LMICs). However, the current prevalence and recent changes of anemia among young children and women of reproductive age, particularly for pregnant women in different trimesters are unclear. We examined the current prevalence of anemia among children aged less than 5 years by age (6-35 months vs. 36-59 months) and women of reproductive age by pregnant status (pregnant vs. non-pregnant) and trimesters (the third vs. the second vs. the first trimester) between 2010 and 2018 and further examined changes in the prevalence from 2000-2009 to 2010-2018. METHODS Data were from the cross-sectional Demographic and Health Surveys performed between 2000 and 2018. A total of 47 countries were included to examine the current prevalence of anemia (weighted prevalence and 95% confidence interval [CI]) among young children aged less than 5 years (N = 459,785) and 46 countries among women of reproductive age (N = 1,079,805) between 2010 and 2018. To examine changes in the prevalence of anemia, a total of 29 countries with at least two Demographic and Health Surveys performed between 2000 and 2009 (children: N = 130,772; women: N = 371,845) and 2010-2018 (children: N = 386,202; women: N = 928,889) were included. Modified Poisson regression analyses with robust error variance were used to examine changes in anemia between 2000-2009 and 2010-2018 in participants by child age (6-5 months vs. 36-59 months), women pregnant status (pregnant vs. non-pregnant), trimesters (the second or third trimester vs. the first trimester) with the adjustment for potential covariates. FINDINGS In 47 LMICs for children aged less than 5 years between 2010 and 2018, the total prevalence of anemia was 56.5% (95% CI 56.2, 56.8). Younger children aged 6-35 months were more likely to have anemia than older children aged 36-59 months (adjusted odds ratio [OR] 1.38, 95% CI 1.36-1.39, P < 0.001). In 46 LMICs for women of reproductive age, the total prevalence was 40.4% (95% CI 40.1, 40.7). Pregnant women were more likely to have anemia than non-pregnant women (adjusted OR 1.14, 1.12-1.16, P < 0.001). Moreover, pregnant women in the third trimester (adjusted OR 1.55, 1.48-1.62, P < 0.001) and the second trimester (adjusted OR 1.51, 1.45-1.58, P < 0.001) were more likely to have anemia than those in the first trimester. Among 29 included countries, although there was a decreasing change (absolute change, relative change, and average annual rate of reduction) in young children and women between 2000-2009 and 2010-2018 in a majority of countries, the current prevalence of anemia remained at a high level. INTERPRETATION The prevalence of anemia among children aged less than 5 years and women of reproductive age was still high in LMICs, particularly for younger children and pregnant women. The relative change among women of reproductive age was far away from the WHO goal of reduction of anemia by 50% by 2025 (i.e., prevalence reduction to about 15.2% by 2025 from 30.3% at 2012 baseline). Continued and effective efforts, particularly for high-risk populations, are needed to improve the general health of the population.

Abstract
BACKGROUND Anemia is an etiologically heterogeneous condition affecting over half of preschool-aged children in South Asia. An urgent need exists to elucidate context-specific causes of anemia to effectively address this issue. OBJECTIVES This study investigated national trends and stability in the prevalence of child anemia and associated risk factors from 2013 to 2016 in Nepal. METHODS Same-season national surveys were administered in 2013, 2014, and 2016 in 63 sites across 21 districts, selected using multistage random sampling, representing the mountains, hills, and Tarai (plains). Among consenting households with children aged 6-59 mo, a random sample of capillary blood was selected each year for anemia assessment using an Hb 201+ hemoglobinometer, with n = 835, 807, and 881 children assessed, respectively. Prevalence of child anemia, defined as hemoglobin <11.0 g/dL with adjustment for altitude, was estimated each year and disaggregated by region and child age. Prevalence ratios were estimated using log-binomial regression models with robust SE or robust Poisson regression when models failed to converge. Interaction terms between each risk factor and year were created to test for consistencies in associations over time. RESULTS The national prevalence of child anemia decreased from 63.3% (95% CI: 59.0%, 67.5%) in 2013 to 51.9% (95% CI: 46.5%, 57.2%) in 2014 and increased to 59.3% (95% CI: 54.7%, 63.8%) in 2016. Across years, prevalence was highest in the Tarai (58.4-70.2%), followed by the mountains (53.0-61.1%) and hills (37.5-51.4%). Nationally and across time, child age and maternal anemia were significantly associated with child anemia. Child diarrhea and stunting, maternal thinness, and poor water and sanitation conditions also showed consistent trends toward higher anemia prevalence. CONCLUSIONS Anemia affects more than half of Nepalese children aged 6-59 mo. Although prevalence varies year to year, the stability of observed risk factors suggests the need to focus on reducing gastrointestinal infection, promoting adequate household sanitation, and improving maternal and child health.

Abstract
Anaemia is a global public health problem affecting women worldwide, and reproductive-age women are at increased risk. We conducted a population-based cross-sectional study analysing the prevalence of overall anaemia and anaemia according to severity in Chinese pre-pregnant women to update current knowledge on anaemia epidemiology. Based on the National Free Preconception Check-up Projects supported by the Chinese government, 5 679 782 women participating in this project in 2017 were included in the present study. The cyanmethemoglobin method was applied to assess Hb concentrations. Univariate and multivariate logistic regressions were applied for associated factors. The prevalence of anaemia among Chinese pre-pregnant women was 21·64 % (mild: 14·10 %, moderate: 7·17 % and severe : 0·37 %). The prevalence of overall and severe anaemia was the highest in Tibet and the lowest in Beijing among thirty-one provinces. Women's age, region, ethnic origin, educational level, occupation and pregnancy history were all correlated with anaemia. Women with B blood type (adjusted OR (aOR) = 0·89), higher BMI (overweight: aOR = 0·84; obesity: aOR = 0·70) and alcohol consumption (aOR = 0·69) were less likely to have anaemia, while those with rhesus negative blood type (aOR = 1·10), history of anaemia (aOR = 2·60), older age at menarche (aOR = 1·19), heavy menstrual blood loss (aOR = 1·39), longer menstrual period (aOR = 1·09) and shorter menstrual cycle (aOR = 1·08) were more likely to suffer from anaemia. Meat or egg eaters were not significantly associated with severe anaemia. Anaemia is of moderate public health significance among Chinese pre-pregnant women. Interventions should be considered to prevent anaemia to the greatest extent possible to avoid potential harm in this population.

Abstract
INTRODUCTION The importance of iron is highlighted by the many complex metabolic pathways in which it is involved. A sufficient supply is essential for the effective production of 200 billion erythrocytes daily, a process called erythropoiesis. AREAS COVERED During infection, the human body can withhold iron from pathogens, mechanism termed nutritional immunity. The subsequent disturbances in iron homeostasis not only impact on immune function and infection control, but also negatively affect erythropoiesis. The complex interplay between iron, immunity, erythropoiesis and infection control on the molecular and clinical level are highlighted in this review. Diagnostic algorithms for correct interpretation and diagnosis of the iron status in the setting of infection are presented. Therapeutic concepts are discussed regarding effects on anemia correction, but also toward their role on the course of infection. EXPERT OPINION In the setting of infection, anemia is often neglected and its impact on the course of diseases is incompletely understood. Clinical expertise can be improved in correct diagnosing of anemia and disturbances of iron homeostasis. Systemic studies are needed to evaluate the impact of specific therapeutic interventions on anemia correction on the course of infection, but also on patients' cardiovascular performance and quality of life.

Abstract
Previous studies have suggested an association of anemia with hearing loss. The aim of this study was to investigate the association of nutritional anemia with sudden sensorineural hearing loss (SSNHL), as previous studies in this aspect are lacking. We analyzed data from the Korean National Health Insurance Service-Health Screening Cohort 2002-2015. Patients with SSNHL (n = 9393) were paired with 37,572 age-, sex-, income-, and region of residence-matched controls. Both groups were assessed for a history of nutritional anemia. Conditional logistic regression analyses were performed to calculate the odds ratios (ORs) (95% confidence interval, CI) for a previous diagnosis of nutritional anemia and for the hemoglobin level in patients with SSNHL. Subgroup analyses were conducted for age and sex. Age, sex, income, and region of residence were stratified. Obesity, smoking, drinking alcohol, systolic/diastolic blood pressure, fasting blood glucose, total cholesterol, and the Charlson Comorbidity Index were considered in the regression models. Nutritional anemia was present in 4.8% (449/9393) of patients with SSNHL and 4.0% (1494/37,572) of controls (p < 0.001). The SSNHL group demonstrated 1.20-fold higher odds for nutritional anemia (95% CI = 1.08-1.34, p = 0.001). Hemoglobin levels were not associated with SSNHL. In subgroups <60 years old, there was a consistent positive association of nutritional anemia with SSNHL (adjusted OR = 1.55, 95% CI = 1.11-2.15, p = 0.010 for men <60 years old, and adjusted OR = 1.22, 95% CI = 1.02-1.45, p = 0.028 for women <60 years old). Nutritional anemia, but not hemoglobin level, was associated with an increased risk of SSNHL.

Abstract
Danggui Buxue Decoction (DBD), a famous traditional Chinese medicine (TCM), is often used to treat anemia in China. However, its underlying therapeutic mechanism is unclear. Through the analysis of body weight, spleen and thymus indexes, peripheral blood routine and pathological section of femur, it was obviously that DBD could significantly improve acetylphenylhydrazine (APH) + cyclophosphamide (CTX) induced anemia mice in the present work. Ultra high performance liquid chromatography coupled with quadrupole - Exactive mass spectrometry (UHPLC Q-Exactive MS) based metabolomics and lipidomics was further utilized to screen out differential spleen metabolites associated with DBD treatment. A total of 26 differential metabolites including 8 polar metabolites and 18 lipids were firstly obtained to relate with anemia mice. 7 polar metabolites and 10 lipids among them were reversed by DBD, which the regulation of pyrimidine metabolism and glycerophospholipid metabolism were mainly associated to the anti-anemia effect of DBD based on MetaboAnalyst analysis. Through random forest analysis (RF), ROC analysis and pearson matrix correlation, three metabolites, cytosine, uracil and PC (o-16:1(9Z)/20:0), were further screened out as the potential pharmacodynamic biomarkers associated with the efficacy of DBD. This study provided a methodological reference for the study of the mechanism of TCM.

Evaluating the nutritional content of an insect-fortified food for the child complementary diet in Ghana. BMC Nutr 2020; 6:7. [PMID: 32266077 PMCID: PMC7114796 DOI: 10.1186/s40795-020-0331-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2018] [Accepted: 01/27/2020] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Due to rising food insecurity, natural resource scarcity, population growth, and the cost of and demand for animal proteins, insects as food have emerged as a relevant topic. This study examines the nutrient content of the palm weevil larva (Rhynchophorus phoenicis), a traditionally consumed edible insect called akokono in Ghana, and assesses its potential as an animal-source, complementary food. METHODS Akokono in two "unmixed" forms (raw, roasted) and one "mixed" form (akokono-groundnut paste) were evaluated for their macronutrient, micronutrient, amino acid, and fatty acid profiles. RESULTS Nutrient analyses revealed that a 32 g (2 tbsp.) serving of akokono-groundnut paste, compared to recommended daily allowances or adequate intakes (infant 7-12 months; child 1-3 years), is a rich source of protein (99%; 84%), minerals [copper (102%; 66%), magnesium (54%; 51%), zinc (37%; 37%)], B-vitamins [niacin (63%; 42%), riboflavin (26%; 20%), folate (40%; 21%)], Vitamin E (a-tocopherol) (440%; 366%), and linoleic acid (165%; 108%). Feed experiments indicated that substituting palm pith, the typical larval diet, for pito mash, a local beer production by-product, increased the carbohydrate, potassium, calcium, sodium, and zinc content of raw akokono. Akokono-groundnut paste meets (within 10%) or exceeds the levels of essential amino acids specified by the Institute of Medicine criteria for animal-source foods, except for lysine. CONCLUSIONS Pairing akokono with other local foods (e.g., potatoes, soybeans) can enhance its lysine content and create a more complete dietary amino acid profile. The promotion of akokono as a complementary food could play an important role in nutrition interventions targeting children in Ghana.

Abstract
Polygoni multiflori Radix Praeparata (PMRP) is a traditional medicine used for nourishing essence and blood in China. However, it is unclear which PMRP compounds are responsible for its hematopoietic effect. In this study, spectrum-effect relationship was used to discovery potential hematopoietic compounds. The fingerprints of 20 PMRP batches were established by HPLC and the hematopoietic effect was determined using red blood cell, hemoglobin, hematocrit, and platelet indexes in aplastic anemia model mice. The spectrum-effect relationship between common peaks and hematopoietic efficacy values was established using gray relational analysis and partial least squares analysis. Spectrum-effect relationship results showed that peaks 21 (emodin-8-O-(6´-O-acetyl)-β-D-glucoside), 15 (2, 3, 5, 4'-tetrahydroxystilbene-2-O-di-glucoside), 16 (cis-2,3,5,4'-tetrahydroxy-stilbene-2-O-β-D-glucoside), 11 (unknown), 20(unknown, 12 (epicatechin), 29 (carboxyl emodin), and 31 (emodin) in the fingerprints were closely related to the hematopoietic effect. This work successfully established the spectrum-effect relationship between PMRP hematopoietic effect and its fingerprints, which can be used to explain the material basis for the PMRP hematopoietic effect.

Abstract
Background: Periodontitis is a chronic inflammatory disease with a possible infectious component. Anemia of inflammation (AI) occurring in various chronic diseases alters the hemoglobin (Hb) concentration and iron status. Currently, the association between periodontitis and AI is still controversial. The aim of this study was to assess the alterations of the level of hematological parameters and iron metabolism markers in patients with or without periodontitis. Methods: Electronic databases (MEDLINE, EMBASE, and Cochrane) were searched to identify publications about anemia and periodontitis. Subgroup analyses regarding gender, extent of periodontitis, and sample size were performed using STATA 12.1. Results: Sixteen studies were included in this meta-analysis. Pooled results showed a decrease in Hb [standardized mean difference (SMD) = −0.76, 95% CI = (−1.15, −0.37)], red blood cell [SMD = −0.69, 95% CI = (−1.09, −0.29)], hematocrit [SMD = −1.13, 95% CI = (−1.69, −0.57)], mean corpuscular volume [SMD = −0.16, 95% CI = (−0.32, −0.01)], and mean corpuscular Hb [SMD = −0.16, 95% CI = (−0.28, −0.04)], but upregulation in erythrocyte sedimentation rate [SMD = 0.63, 95% CI = (0.06, 1.19)]. In addition, patients with periodontitis had a higher level of hepcidin [SMD = 0.59, CI = (0.05, 1.12)] and decreased level of transferrin [SMD = −4.6, CI = (−13.1, −3.90)], with high heterogeneity. Conclusion: This meta-analysis indicates that periodontitis decreases Hb concentration and disturbs the balance of iron metabolism, which confirms strength of association between periodontitis and the development tendency of AI, especially for severe periodontitis. More unbiased cohort studies with larger sample sizes are still warranted to make a definitive judgment in the future.

Abstract
Women's empowerment is associated with improved child nutrition, and both underpin the achievement of multiple Sustainable Development Goals (SDGs). We examined pathways by which women's empowerment influences child nutritional status. We pooled nationally representative data from Demographic and Health Surveys (2011-2016) collected from married women with children aged 6-24 months in Ethiopia, Kenya, Rwanda, Tanzania, and Uganda (n = 13,780). We operationalized child nutritional status using anemia, height-for-age z-score (HAZ), and weight-for-age z-score (WHZ). We operationalized women's empowerment using a validated measure comprised of three latent domains: social/human assets ("assets"), intrinsic agency (attitudes about intimate partner violence), and instrumental agency (influence in household decision making). We used structural equation models with latent constructs to estimate hypothesized pathways from women's empowerment to child nutritional status with further mediation by maternal body mass index (BMI) and stratification by wealth. Women's empowerment domains were directly and positively associated with maternal BMI (estimate±SE: assets, 0.17 ± 0.03; intrinsic agency, 0.23 ± 0.03; instrumental agency, 0.03 ± 0.01). Maternal BMI was directly and positively associated with child HAZ (0.08 ± 0.04) and child WHZ (0.35 ± 0.03). Assets were indirectly associated with child HAZ and WHZ through intrinsic agency and maternal BMI. In the lowest wealth category, the direct effects from women's empowerment to child nutritional status were significant (assets and instrumental agency were associated with anemia; intrinsic agency associated with HAZ). In the highest wealth category, direct effects from women's empowerment on child nutritional status were significant (intrinsic and instrumental agency associated with WHZ). Improving women's empowerment, especially intrinsic agency, in East Africa could improve child nutrition directly and via improved maternal nutrition. These findings suggest that efforts to realize SDG 5 may have spillover effects on other SDGs. However, strategies to improve nutrition through empowerment approaches may need to also address household resource constraints.
