Asymptomatic malaria in pregnancy and associated risk factors in Majang Zone, Gambella Region, Southwest Ethiopia: a hard-to-reach malaria hotspot.

BACKGROUND: Asymptomatic malaria in pregnancy (AMiP) is a daunting public health problem with multifaceted adverse outcomes for mothers, fetuses, newborns and beyond. This study aimed to assess the prevalence and risk factors of AMiP and anaemia in Majang Zone, Gambella, Southwest Ethiopia. METHODS: A facility-based cross-sectional study was conducted among 425 pregnant women attending the antenatal care (ANC) clinics of five health facilities in the Majang Zone from November 2022 to February 2023. Sociodemographic, obstetric, and anti-malarial intervention data were collected using an interviewer-administered questionnaire. A capillary blood specimen was collected to diagnose malaria and anaemia as well as determine the blood group. Malaria was diagnosed by rapid diagnostic test (RDT), microscopy, and quantitative polymerase chain reaction (qPCR). Statistical analyses were done by Statistical Package for Social Science (SPSS) version 26.0. The association between dependent and independent variables was assessed by multivariable binary logistic regression, considering P < 0.05 statistically significant. The magnitude of associations was quantified with the adjusted odds ratio (AOR) along with the corresponding 95% confidence interval (CI). RESULTS: The overall prevalence of AMiP was 15.3% (95% CI 12.1, 18.9). It was 11.3% (95% CI 8.4, 14.7) by RDT, 11.8% (95% CI 8.9, 15.2) by microscopy and 17.6% (95% CI 11.7, 24.9) by qPCR. Plasmodium falciparum, moderate parasitaemia and submicroscopic infection accounted for 55.4% of the AMiP prevalence, 50.8% of the parasite density, and 41.6% of the qPCR-positive AMiP, respectively. Nearly 32.3% of pregnant women with AMiP carried gametocytes. Risk factors of AMiP were: not utilizing insecticide-treated net (ITN) within the previous week (AOR: 9.43 95% CI 1.57, 56.62), having a history of malaria within the previous year (AOR: 2.26 95% CI 1.16, 4.42), lack of indoor residual spraying (IRS) within the previous year (AOR: 3.00 95% CI 1.50, 6.00), and ANC contact below two rounds (AOR: 4.28 95% CI 2.06, 8.87). The prevalence of anaemia was 27.7% (95% CI 23.6, 32.1), and it was higher among AMiP-positives (56.9%) than the negatives (22.5%) (P: 000). CONCLUSION: The prevalence of AMiP and anaemia was high, and remained as a critical public health problem in the study area. Focus on the identified risk factors and introduction of more sensitive diagnostic tools should be considered to mitigate AMiP in the study area.

Short-term effect of low-dose roxadustat combined with erythropoiesis-stimulating agent treatment for erythropoietin-resistant anemia in patients undergoing maintenance hemodialysis.

Background: Erythropoietin resistance is present in some patients with chronic kidney disease, especially in those undergoing hemodialysis, and is often treated using roxadustat rather than iron supplements and erythropoiesis-stimulating agents (ESAs). However, some patients cannot afford full doses of roxadustat. This retrospective study investigated the efficacy of low-dose roxadustat combined with recombinant human erythropoietin (rhuEPO) therapy in 39 patients with erythropoietin-resistant renal anemia undergoing maintenance hemodialysis (3-4 sessions/week). Methods: The ability of the combination of low-dose roxadustat and rhuEPO to increase the hemoglobin concentration over 12 weeks was assessed. Markers of iron metabolism were evaluated. Eligible adults received 50-60% of the recommended dose of roxadustat and higher doses of rhuEPO. Results: The mean hemoglobin level increased from 77.67 ± 11.18 g/dL to 92.0 ± 8.35 g/dL after treatment, and the hemoglobin response rate increased to 72%. The mean hematocrit level significantly increased from 24.26 ± 3.99% to 30.04 ± 3.69%. The soluble transferrin receptor level increased (27.29 ± 13.60 mg/L to 38.09 ± 12.78 mg/L), while the total iron binding capacity (49.22 ± 11.29 mg/L to 43.91 ± 12.88 mg/L) and ferritin level (171.05 ± 54.75 ng/mL to 140.83 ± 42.03 ng/mL) decreased. Conclusion: Therefore, in patients with ESA-resistant anemia who are undergoing hemodialysis, the combination of low-dose roxadustat and rhuEPO effectively improves renal anemia and iron metabolism.

Predicting postacute phase anaemia after aneurysmal subarachnoid haemorrhage: nomogram development and validation.

BACKGROUND: Anaemia is a severe and common complication in patients with aneurysmal subarachnoid haemorrhage (aSAH). Early intervention for at-risk patients before anaemia occurs is indicated as potentially beneficial, but no validated method synthesises patients' complicated clinical features into an instrument. The purpose of the current study was to develop and externally validate a nomogram that predicted postacute phase anaemia after aSAH. METHODS: We developed a novel nomogram for aSAH patients to predict postacute phase anaemia (3 days after occurrence of aSAH, prior to discharge) on the basis of demographic information, imaging, type of treatment, aneurysm features, blood tests and clinical characteristics. We designed the model from a development cohort and tested the nomogram in external and prospective validation cohorts. We included 456 aSAH patients from The First Affiliated Hospital for the development, 220 from Sanmen People's Hospital for external validation and a prospective validation cohort that included 13 patients from Hangzhou Red Cross Hospital. We assessed the performance of the nomogram via concordance statistics and evaluated the calibration of predicted anaemia outcome with observed anaemia occurrence. RESULTS: Variables included in the nomogram were age, treatment method (open surgery or endovascular therapy), baseline haemoglobin level, fasting blood glucose level, systemic inflammatory response syndrome score on admission, Glasgow Coma Scale score, aneurysm size, prothrombin time and heart rate. In the validation cohort, the model for prediction of postacute phase anaemia had a c-statistic of 0.910, with satisfactory calibration (judged by eye) for the predicted and reported anaemia outcome. Among forward-looking forecasts, our predictive model achieved an 84% success rate, which showed that it has some clinical practicability. CONCLUSIONS: The developed and validated nomogram can be used to calculate individualised anaemia risk and has the potential to serve as a practical tool for clinicians in devising improved treatment strategies for aSAH.

The effect of erythropoiesis­stimulating agents on lung cancer patients: a meta­analysis.

Previous studies have demonstrated that erythropoiesis-stimulating agents (ESAs) can reduce anemia and improve quality of life in cancer patients, but ESAs may increase mortality. Therefore, we conducted a meta-analysis of randomized controlled trials (RCT) comparing the effect and risk of ESAs about the prevention or treatment of anemia in cancer patients. Four databases including PubMed, Embase, Web of science and Cochrane Library were searched for published RCTS on ESAs in the treatment of anemia in lung cancer patients from 2000 to 2023. Endpoints including mortality, incidence of thrombotic vascular events, blood transfusion requirement, and incidence of adverse events. Our meta-analysis included 8 studies, with a sample size of 4240 patients, including 2548 patients in the ESAs group and 1692 patients in the control group. The risk of mortality was lower in patients using ESAs than control group (RR 0.96, 95% CI 0.92-0.99, P = 0.02). But there was no significant difference in the risk of mortality between the patients using ESAs and controls (RR 0.99, 95% CI 0.92-1.06, P = 0.69) after removing Pere 2020. Subgroup analysis found that patients diagnosed with small cell lung cancer (SCLC) (RR 1.00, 95% CI 0.92-1.08, P = 0.16) or non-small cell lung cancer (NSCLC) (RR 1.01, 95% CI 0.87-1.17, P = 0.13) were no significant difference in mortality rate. The thrombotic vascular events increase in patients using ESAs than control group (RR 1.40, 95% CI 1.13-1.72, P = 0.002). The blood transfusion requirement of ESAs group was lower than control group (RR 0.56, 95% CI 0.44-0.72, P < 0.00001). And the subgroups of Darbepoetin alfa (RR 0.57, 95% CI 0.41-0.79, P = 0.003) and Epoetin alfa (RR 0.68, 95% CI 0.47-0.99, P = 0.01) had lower transfusion requirements than the control group. In the SCLC subgroup (RR 0.51, 95% CI 0.40-0.65, P = 0.34), blood transfusion requirements were lower in the ESAs group, but there was no significant difference between the subgroup of patients with NSCLC (RR 0.61, 95% CI 0.36-1.04, P = 0.009). There was no statistically significant difference between the two groups in the incidence of adverse reactions (RR 0.98, 95% CI 0.95-1.00, P = 0.10). In conclusion, ESAs does not increase the mortality of lung cancer patients or may reduce the risk of death, and can reduce the need for blood transfusion, although ESA can increase the incidence of thrombotic vascular adverse events.Registration PROSPERO CRD42023463582.

The Effect of Varying Preoperative Hemoglobin Levels on the Risk of Major Complications and Surgical Site Infections After Single Level Lumbar Fusion.

INTRODUCTION: Blood transfusions are associated with an increased risk of complications after lumbar fusion, and current anemia hemoglobin thresholds are not surgery specific. We aimed to calculate single-level lumbar fusion-specific preoperative hemoglobin strata that observe the likelihood of 90-day transfusion and evaluate whether these strata are associated with increased risk of 90-day complications and 2-year infections. METHODS: A national database identified patients undergoing primary single-level lumbar fusion with preoperative hemoglobin values (g/dL). Stratum-specific likelihood ratio analysis calculated sex-based hemoglobin strata associated with the risk of 90-day transfusion. Incidence and risk of 90-day major complications and 2-year infections were observed between strata. RESULTS: Three female (hemoglobin strata, likelihood ratio [<10.9, 2.41; 11.0 to 12.4, 1.35; 12.5 to 17.0, 0.78]) and male (<11.9, 2.95; 12.0 to 13.4, 1.46; 13.5 to 13.9, 0.71) strata were associated with varying likelihood of 90-day blood transfusion. Increased 90-day complication risk was associated with two female strata (hemoglobin strata, relative risk [11.0 to 12.4, 1.52; <10.9, 3.40]) and one male stratum (<11.9, 2.02). Increased 2-year infection risk was associated with one female (<10.9, 3.67) and male stratum (<11.9, 2.11). CONCLUSION: Stratum-specific likelihood ratio analysis established sex-based single-level lumbar fusion-specific hemoglobin strata that observe the likelihood of 90-day transfusion and the risk of 90-day major complications and 2-year infections. These thresholds are a unique addition to the literature and can assist in counseling patients on their postoperative risk profile and in preoperative patient optimization.

Treatment of Anemia Associated with Chronic Kidney Disease: Plea for Considering Physiological Erythropoiesis.

Traditionally, the treatment of anemia associated with chronic kidney disease (CKD) involves prescribing erythropoiesis-stimulating agents (ESAs) or iron preparations. The effectiveness and safety of ESAs and iron have been established. However, several clinical issues, such as hyporesponsiveness to ESAs or defective iron utilization for erythropoiesis, have been demonstrated. Recently, a new class of therapeutics for renal anemia known as hypoxia-inducible factor (HIF)/proline hydroxylase (PH) inhibitors has been developed. Several studies have reported that HIF-PH inhibitors have unique characteristics compared with those of ESAs. In particular, the use of HIF-PH inhibitors may maintain target Hb concentration in patients treated with a high dose of ESAs without increasing the dose. Furthermore, several recent studies have demonstrated that patients with CKD with defective iron utilization for erythropoiesis had a high risk of cardiovascular events or premature death. HIF-PH inhibitors increase iron transport and absorption from the gastrointestinal tract; thus, they may ameliorate defective iron utilization for erythropoiesis in patients with CKD. Conversely, several clinical problems, such as aggravation of thrombotic and embolic complications, diabetic retinal disease, and cancer, have been noted at the time of HIF-PH inhibitor administration. Recently, several pooled analyses of phase III trials have reported the non-inferiority of HIF-PH inhibitors regarding these clinical concerns compared with ESAs. The advantages and issues of anemia treatment by ESAs, iron preparations, and HIF-PH inhibitors must be fully understood. Moreover, patients with anemia and CKD should be treated by providing a physiological erythropoiesis environment that is similar to that of healthy individuals.

Mechanisms and treatment of anemia related to cardiac arrest. / å¿ƒè„éª¤åœåŽç›¸å ³æ€§è´«è¡€çš„æœºåˆ¶åŠæ²»ç–—.

Cardiac arrest is a common and fatal emergency situation. Recently, an increasing number of studies have shown that anemia in patients with cardiac arrest is closely related to high mortality rates and poor neurological outcomes. Anemia is prevalent among patients with post-cardiac arrest syndrome (PCAS), but its specific pathogenesis remains unclear. The mechanisms may involve various factors, including reduced production of erythropoietin, oxidative stress/inflammatory responses, gastrointestinal ischemic injury, hepcidin abnormalities, iatrogenic blood loss, and malnutrition. Measures to improve anemia related to cardiac arrest may include blood transfusions, administration of erythropoietin, anti-inflammation and antioxidant therapies, supplementation of hematopoietic materials, protection of gastrointestinal mucosa, and use of hepcidin antibodies and antagonists. Therefore, exploring the latest research progress on the mechanisms and treatment of anemia related to cardiac arrest is of significant guiding importance for improving secondary brain injury caused by anemia and the prognosis of patients with cardiac arrest.

Association between exposure to smoke from cooking fuels and anaemia among women of reproductive age in Ghana.

In low- and middle-income countries, indoor air pollution (IAP) is a serious public health concern, especially for women and children who cook with solid fuels. IAP exposure has been linked to a number of medical conditions, including pneumonia, ischemic heart disease, stroke, chronic obstructive pulmonary disease (COPD), lung cancer, and anaemia. Around 500 million women of reproductive age (WRA) suffer from anaemia globally, with an estimated 190 million cases in sub-Saharan Africa (SSA). This study, which is based on prior research, investigates the relationship between IAP exposure and anaemia among WRA in Ghana. A diverse sample of 2,406 WRA living in Ghana were interviewed, of which 58.06% were anaemic and used high-pollutant fuels for cooking. Age, place of residence, region, education level, religion, ethnicity, wealth index, type of drinking water, type of toilet facility, and type of cooking fuels were all found to be significantly linked with anaemic state by bivariate analysis. Type of cooking fuels utilized, age, region of residence, and the type of residence were shown to be significant predictors of anaemia status using sequential binary logit regression models. The results emphasise the critical need for efforts to promote the usage of clean cooking fuel in an attempt to lower anaemia prevalence in Ghana. To reduce dependency on solid fuels for cooking, initiatives should promote the use of cleaner cooking fuels and enhance the socioeconomic status of households. These interventions could have significant public health effects by reducing the burden of anaemia and improving maternal and child health outcomes due to the prevalence of anaemia among WRA. Overall, this study sheds light on the relationship between IAP exposure and anaemia in Ghana and highlights the demand for focused public health initiatives to address this serious health problem.

The role of severity and duration of inflammation and hematological parameters on the outcome of subacute thyroiditis.

Background: The role of severity and duration of inflammatory findings on the development of persistent hypothyroidism and anemia has not been clarified in subacute thyroiditis (SAT). Methods: Demographic data and laboratory parameters of patients with SAT were analyzed retrospectively. Results: Permanent hypothyroidism was observed in 28.1% of patients. Baseline elevated erythrocyte sedimentation rate as defined >74.5 mm/h was found to be associated with permanent hypothyroidism, but the duration of inflammation was not different between the recovered and hypothyroid patients. Baseline hemoglobin values improved without specific therapy in 3.5 months. Conclusion: The initial severity but not the duration of inflammation increases the risk for the development of permanent thyroid dysfunction, and anemia improves with the resolution of inflammation.

Anemia From Inflammation After Intracerebral Hemorrhage and Relationships With Outcome.

BACKGROUND: Baseline anemia is associated with poor intracerebral hemorrhage (ICH) outcomes. However, underlying drivers for anemia and whether anemia development after ICH impacts clinical outcomes are unknown. We hypothesized that inflammation drives anemia development after ICH and assessed their relationship to outcomes. METHODS AND RESULTS: Patients with serial hemoglobin and iron biomarker concentrations from the HIDEF (High-Dose Deferoxamine in Intracerebral Hemorrhage) trial were analyzed. Adjusted linear mixed models assessed laboratory changes over time. Of 42 patients, significant decrements in hemoglobin occurred with anemia increasing from 19% to 45% by day 5. Anemia of inflammation iron biomarker criteria was met in 88%. A separate cohort of 521 patients with ICH with more granular serial hemoglobin and long-term neurological outcome data was also investigated. Separate regression models assessed whether (1) systemic inflammatory response syndrome (SIRS) scores related to hemoglobin changes over time and (2) hemoglobin changes related to poor 90-day outcome. In this cohort, anemia prevalence increased from 30% to 71% within 2 days of admission yet persisted beyond this time. Elevated systemic inflammatory response syndrome was associated with greater hemoglobin decrements over time (adjusted parameter estimate: -0.27 [95% CI, -0.37 to -0.17]) and greater hemoglobin decrements were associated with poor outcomes (adjusted odds ratio per 1 g/dL increase, 0.76 [95% CI, 0.62-0.93]) independent to inflammation and ICH severity. CONCLUSIONS: We identified novel findings that acute anemia development after ICH is common, rapid, and related to inflammation. Because anemia development is associated with poor outcomes, further work is required to clarify if anemia, or its underlying drivers, are modifiable treatment targets that can improve ICH outcomes.

Assessment of the impact of cytomegalovirus seropositivity on blood parameters in renal hemodialysis patients.

End-stage renal disease (ESRD) patients are considered immunocompromised, putting them at high risk for infections, including cytomegalovirus (CMV). CMV can affect hematological parameters, causing further complications in ESRD patients. This study intended to determine the seropositivity of CMV infection in hemodialysis patients and its effect on different blood parameters in ESRD patients to help decrease the overall dialysis associated morbidity and mortality. Blood samples were collected from 45 ESRD patients and 45 controls. A complete blood count was performed using an automated cell counter. CMV-specific IgM and IgG levels were measured using immunochemistry testing. The seropositivity for CMV-IgG was 42.2% in ESRD patients which was significantly higher than in control group (22.2%) (p=0.042). The seropositivity for CMV-IgM was 6.7% in ESRD patients with no difference with the control group (4.4%). The prevalence of anemia was significantly higher in CMV seropositive (77.3%) compared to CMV seronegative (47.8%) ESRD patients. Other studied blood parameters were not different between CMV seronegative and seropositive ESRD patients. In conclusion, CMV infection is a significant concern for dialysis patients and can affect hematological parameters, leading to further complications. Early detection and treatment of CMV infection and monitoring of CMV IgM and IgG levels are critical to prevent further complications and improve clinical outcomes.

Anaemia among adolescent girls, pregnant and lactating women in the southern rural region of Bangladesh: Prevalence and risk factors.

Anaemia is a major public health concern in developing countries, particularly among children, adolescents, and women of reproductive age. The study aimed to assess the anaemia status among adolescent girls, pregnant, and lactating women with their contributing factors in the southern rural regions of Bangladesh. This cross-sectional study was conducted among 400 adolescent girls, 375 pregnant, and 375 lactating women using a multistage cluster-random sampling technique. Anaemia was measured through haemoglobin concentration in blood capillaries collected with a Hemocue 301 machine. Multinomial logistic regression was used to determine the factors associated with anaemia. The average age of pregnant and lactating women was 24 years and 15.2 years for girls. Overall, the prevalence of anaemia was 50% among pregnant women, 46% among lactating women, and 38% among adolescent girls. The risk of anaemia among adolescent girls was higher among non-Muslim (aOR = 2.13, 95%CI:1.05-4.31), belonged to families having >5 members (aOR = 2.24, 95%CI:1.16-4.31) while exposure to media reduced their risk (aOR = 0.33, 95%CI:0.15-0.74). Pregnant women who consumed a diversified diet, washed their hands after toilet, and received ≥4 ANC visits had a lower likelihood of developing anaemia. Lactating women who were employed, consumed a diversified diet, washed their hands before preparing food, and after toilet, had been exposed to media, received ≥4 ANC visits, and consumed ≥90 IFA, had a lower risk of developing anaemia. However, anaemia was more likely to be associated with lactating women who were non-Muslim (aOR = 3.75; 95%CI:1.26-11.22). The high prevalence of anaemia emphasizes the need to reconsider the existing strategy for the prevention and control of micronutrient deficiencies in Bangladesh.

A case report: recurrent anemia related to long term acyclovir use in a pregnant HIV infected Ugandan.

This case report describes a pregnant patient with recent diagnosis of Human Immuno-Deficiency Virus (HIV) infection initiated on Anti-Retroviral Therapy (ART) in the second trimester, as well as high dose acyclovir high for large infected genital warts. She had no other HIV related opportunistic infections, and no prior anti tuberculosis treatment or preventive medication. Despite little response to acyclovir, patient was continuing on acyclovir for over 4 months. She subsequently developed recurrent anemia requiring frequent transfusion (14 units in total) over a 6-week period. On stopping acyclovir, the anemia subsided, a few weeks later she had a normal delivery, followed by surgical removal of the warts. At a follow-up 8 months later, she was well, with a healthy baby, and reported no other episodes of blood transfusion.

Two Cases of False Elevation of MCHC.

BACKGROUND: Mean corpuscular hemoglobin concentration (MCHC) is one of the parameters detected by blood cell analyzers, often used together with mean corpuscular volume (MCV) and mean corpuscular hemoglobin content (MCH) as diagnostic indicators for anemia classification. It has important clinical value in early detection of the cause of anemia and the underlying etiology of anemia. Therefore, the accuracy of MCHC results is of great significance for the diagnosis and treatment of diseases. METHODS: We reported two cases of false elevation of MCHC. Considering the possibility of cold agglutination and lipid blood interference detection, we used 37℃ water bath and plasma exchange to correct for interference on the sample. RESULTS: After correcting the interference, MCHC returned to normal, consistent with the patient's disease status. Therefore, the two cases of abnormal elevation of MCHC are considered to be pseudo elevation caused by interference. CONCLUSIONS: For specimens with abnormally elevated MCHC levels, experimenters should first analyze possible interfering factors and choose effective methods to correct different interferences, providing accurate testing reports for doctors and patients.

The Effect of Preoperative Anemia on the Odds of Allogeneic Blood Transfusion and Patient Outcomes in Colorectal Neoplasm Patients.

BACKGROUND: The optimal preoperative hemoglobin (Hb) value of colorectal neoplasm patients is still being debated. This study aimed at determining the effect of preoperative anemia on patient outcomes and allogeneic blood transfusion (ABT). METHODS: This retrospective cohort study enrolled colorectal neoplasm patients, that underwent surgery, from January 1, 2012, to December 31, 2021. The primary outcomes were the association between anemia and average length of stay (ALOS) and the odds of ABT. The secondary outcomes were the risk factors of the primary outcomes. Univariate and multivariate logistic regression analyses were applied to identify the association and risk factors. RESULTS: A total of 14,352 inpatients were included in the study, of whom 3,035 experienced (21.15%) mild anemia, 1,500 (10.45%) moderate anemia, and 104 (0.72%) severe anemia. Overall, 1,418 (9.88%) patients received ABT during the hospitalization, and 546 (3.80%) patients received perioperative ABT. In the multivariate logistic regression analysis, compared with the no anemic group, the odds ratio [OR] of ABT during the hospitalization for patients with mild/moderate/severe anemia were 5.915, 95% confidence interval [CI]: 4.717 - 7.418; 104.777, 95% CI: 84.345 - 130.160; and 13,361.442, 95% CI: 816.004 - 218,783.511, respectively, and the OR of periopera¬tive ABT were 4.332, 95% CI: 3.245 - 5.785; 27.492, 95% CI: 20.974 - 36.037; and 20.912, 95% CI: 11.832 - 36.959, respectively. Besides, the ALOS was longer, ß were 0.619, 95% CI: 0.346 - 0.892; 1.188, 95% CI: 0.821 - 1.554; and 1.395, 95% CI: 0.107 - 2.684, respectively. CONCLUSIONS: Anemia is a common phenomenon in colorectal neoplasm surgical patients, and even mild anemia could be a deleterious predictor on the outcomes of colorectal neoplasm patients that underwent surgery.

Effect of Diet Counseling on Nutritional Status of Chronic Respiratory Diseases Patients Enrolled in the Pulmonary Rehabilitation Program in a Teaching Hospital: A Pre-Post Intervention Study.

We conducted the study to assess the effect of patient-tailored diet counseling on the nutritional status of chronic respiratory disease (CRD) patients under the pulmonary rehabilitation program from June 2021-May 2022. These patients completed 2 months of patient-tailored diet counseling sessions under the pulmonary rehabilitation program, which consisted of 4-5 interactive diet counseling sessions fortnightly. The pre- and postassessment was done using standardized outcomes: Malnutrition Universal Screening Tool (MUST), body mass index (BMI), and ideal body weight. The study enrolled 110 CRD patients. There was a statistically significant improvement in pre- and postassessment in MUST score, appetite, and unintentional weight loss (P < 0.001). Most of the patient's BMI normalized. In prenutritional assessment, most of the patients were malnourished and in postassessment, the number of malnourished and anemic patients was reduced. This study concludes that nutritional counseling effectively improves nutritional status and anemia.

Retrospective audit compares screening and treatment of pregnancy-related anaemia in regional New South Wales with Australian guidelines.

BACKGROUND: Anaemia during pregnancy is common worldwide. In Australia, approximately 17% of non-pregnant women of reproductive age have anaemia, increasing to a rate of 25% in pregnant women. This study sought to determine the rate of screening for anaemia in pregnancy in regional New South Wales, and to determine whether screening and treatment protocols followed the recommended guidelines. METHODS: This retrospective study reviewed antenatal and postnatal (48 h) data of women (n = 150) who had a live birth at Bathurst Hospital between 01/01/2020 and 30/04/2020. Demographic data, risk factors for anaemia in pregnancy, antenatal bloods, treatments provided in trimesters one (T1), two (T2) and three (T3), and postpartum complications were recorded. These were compared to the Australian Red Cross Guidelines (ARCG) using descriptive statistics. RESULTS: Of the women with screening data available (n = 103), they were mostly aged 20-35yrs (79.6%), 23.3% were obese, 97.1% were iron deficient, 17% were anaemic and only a few (5.3%) completed the full pregnancy screening as recommended by the ARCG while a majority completed only partial screenings specifically Hb levels in T1 (56.7%), T2 (44.7%) and T3 (36.6%). Compliance to oral iron was largely undocumented, but constipation was a common side effect among the women. IV iron was administered in 14.0% of women, approximately 1.75x higher than the recommended rate. CONCLUSIONS: This study provided useful information about compliance to screening and treatment guidelines for anaemia in pregnancy. We identified the need for improved documentation and communication between various health providers to ensure adequate antenatal care to prevent maternal complications during pregnancy. This will improve patient care and encourage further developments in maternal care, bridging the rural health gap.

Association of anaemia with indoor air pollution among older Indian adult population: multilevel modelling analysis of nationally representative cross-sectional study.

INTRODUCTION: Anaemia is a disease of public health importance with multi-causal pathways. Previous literature suggests the role of indoor air pollution (IAP) on haemoglobin levels, but this has been studied less due to logistic constraints. A high proportion of the population in developing countries, including India, still depends on unclean fuel, which exacerbates IAP. The objective was to study the association between anaemia and IAP among the older Indian adult population (≥ 45 years) as per gender. METHODS: Our study analysed the nationally representative dataset of the Longitudinal Ageing Study in India (LASI 2017-18, Wave-1). We have documented the association of anaemia (outcome variable) with IAP (explanatory variable). To reduce the confounding effects of demographic and socioeconomic; health related and behavioural covariates; propensity score matching (PSM) was conducted. Nested multilevel regression modelling was conducted. States and union territories were categorised cross tabulated as low, middle and high as per anaemia and IAP exposure. P value < 0.05 was considered statistically significant. SATA version 17 was used for analysis. RESULTS: More than half (52.52%) of the participants were exposed to IAP (male (53.55%) > female (51.63%)). The odds of having anaemia was significantly 1.19 times higher (AOR 1.19 (1.09-1.31)) among participants using unclean/ solid fuel. The adjusted odds were significantly higher among participants exposed to pollution-generating sources (AOR 1.30; 1.18-1.43), and household indoor smoking (AOR 1.17 (1.07-1.29). The odds of having anaemia were significantly higher (AOR 1.26; 1.15-1.38) among participants exposed to IAP, which was higher in males (AOR 1.36; 1.15-1.61) than females (AOR 1.21; 1.08-1.35). Empowered Action Group (EAG) states like Uttar Pradesh, Chhattisgarh, Madhya Pradesh, Bihar had both high anaemia and IAP exposure. CONCLUSION: This study established the positive association of anaemia with indoor air pollution among older Indian adults through a nationally representative large dataset. The association was higher among men. Further research is recommended to understand detailed causation and to establish temporality. It is a high time to implement positive intervention nationally to decrease solid/ unclean fuel usage, vulnerable ventilation, indoor smoking, IAP and health hazards associated with these with more focused actions towards EAG states.

Anemia Prevalence and Socioeconomic Status among Adolescent Girls in Rural Western India: A Cross-Sectional Study.

Background: Anemia poses a significant challenge among Indian adolescent girls due to their heightened vulnerability, resulting from increased micronutrient requirements, rapid physical growth, menstrual blood loss, inadequate nutrition, and socioeconomic disparities. This study sought to evaluate the prevalence of anemia, along with socioeconomic and nutritional statuses among adolescent girls attending rural public schools in Pune, India. Methods: A sample of 400 girls was selected from 22 villages through Symbiosis International University. Hemoglobin levels were assessed using the HemoCue 201 system, while standardized protocols were employed for height, weight, and BMI-for-age measurements. Socioeconomic status was determined using the Kuppuswamy scale. Results: The findings revealed an overall anemia prevalence of (42.75%), comprising severe (2.5%), moderate (21%) and mild (20.25%) cases. Additionally, a substantial proportion (74.6%) of girls were classified as underweight. Socioeconomic analysis disclosed that 64.25% of families belonged to the lower middle class, and 27% in the upper lower class. Anemia was more prevalent in young adolescent girls (10-14 years) and in the families of adolescents who had low income, were illiterate, unemployed, and belonged to the lower-middle class and upper-lower-class socio-economic status (SES) and did not have a bank account. Conclusion: Anemia was prevalent in adolescent girls and associated with low SES. This study underscores the limitations of relying solely on the distribution of iron and folic acid tablets to combat anemia. A holistic strategy is imperative, encompassing improvements in SES of families (literacy, employment and income), as well as initiatives aimed at enhancing the nutritional status of adolescent girls.

Erythroid-intrinsic activation of TLR8 impairs erythropoiesis in inherited anemia.

Inherited non-hemolytic anemia is a group of rare bone marrow disorders characterized by erythroid defects. Although concerted efforts have been made to explore the underlying pathogenetic mechanisms of these diseases, the understanding of the causative mutations are still incomplete. Here we identify in a diseased pedigree that a gain-of-function mutation in toll-like receptor 8 (TLR8) is implicated in inherited non-hemolytic anemia. TLR8 is expressed in erythroid lineage and erythropoiesis is impaired by TLR8 activation whereas enhanced by TLR8 inhibition from erythroid progenitor stage. Mechanistically, TLR8 activation blocks annexin A2 (ANXA2)-mediated plasma membrane localization of STAT5 and disrupts EPO signaling in HuDEP2 cells. TLR8 inhibition improves erythropoiesis in RPS19+/- HuDEP2 cells and CD34+ cells from healthy donors and inherited non-hemolytic anemic patients. Collectively, we identify a gene implicated in inherited anemia and a previously undescribed role for TLR8 in erythropoiesis, which could potentially be explored for therapeutic benefit in inherited anemia.
