anemia

摘要： BACKGROUND: Anemia is prevalent in patients undergoing transcatheter aortic valve replacement(TAVR) and has been linked to impaired outcomes after the procedure. Few studies have evaluated the impact of anemia and new ischemic lesions post TAVR.METHODS: We prospectively enrolled 158 patients who received TAVR in our center. Anemia was defined according to the World Health Organization criteria as hemoglobin <12 g/dL in women and <13 g/dL in men. All patients underwent diffusion-weighted magnetic resonance imaging(DW-MRI) procedure before and within 4–7 days after TAVR. RESULTS: Anemia was present in 85(53.8%) patients who underwent TAVR, and 126(79.7%) patients had 718 new DW-MRI positive lesions with a mean of 4.54±5.26 lesions per patient. The incidence of new ischemic lesions was 81.2% in patients with anemia versus 78.1% in patients without anemia(P=0.629). Moreover, anemic patients had bigger total volume/lesions in the anterior cerebral artery/middle cerebral artery(ACA/MCA) and MCA regions compared to the non-anemic patients(31.89±55.78 mm^(3) vs. 17.08±37.39 mm^(3), P=0.049;and 54.54±74.72 mm^(3) vs. 33.75±46.03 mm^(3), P=0.034). Anemia was independently associated with the volume/lesion in the ACA/MCA(β=16.796, 95% confidence interval [95% CI] 2.001 to 31.591, P=0.026) and in the MCA zone(β=0.020, 95% CI 0.001 to 0.040, P=0.041). CONCLUSIONS: Patients with pre-procedural anemia may have bigger total volume/lesions in the ACA/MCA and MCA regions compared to the non-anemic patients. Whether the consequences of bigger total volume/lesions impact neurological and cognitive outcomes remains to be investigated.

摘要： The RNA component of mitochondrial RNA-processing endoribonuclease(RMRP)was first described as an entity that cleaved mitochondrial RNA at a priming site of mitochondrial DNA replication.This long noncoding RNA(lncRNA)was encoded by an evolutionarily conserved nuclear gene that has been characterized in many species,including human,mouse,cattle,zebrafish,toad,and yeast.It was soon learned that RMRP as a component of the RNase MRP complex was also located in the nucleus,and was critical for ribosomal RNA(rRNA)processing,particularly the biosynthesis of 5.8S rRNAs.In 2001,the first evidence of the role of RMRP in the pathogenesis of human disorders was reported,involving mutations in the RMRP gene,which caused cartilage-hair hypoplasia(CHH)1,a recessively inherited developmental disorder characterized by short stature,hypoplastic anemia,defective immunity,and predisposition to several cancers.

摘要： Background: Nigeria is currently a malaria endemic country with an estimated 76% of her population at risk of contracting malaria [1]. According to a study in Nigeria, the first line of action mothers took when their children under 5 years have malaria showed that over 50% of them used non-prescription drugs they have at home or bought from pharmacy stores. And 60% of the most commonly used drugs for malaria treatment were chloroquine [2]. Many recent studies have demonstrated re-emergence of chloroquine-sensitive P. falciparum, suggesting a possible role in future malaria control [3]. Objective: The aim of this study was to investigate the effect of home-based oral chloroquine treatment among children under 5 years with Plasmodium falciparum malaria attending Jos University Teaching Hospital and OLA Hospital in Jos Metropolis. Method: This is a cross-sectional study of 93 malaria and non-malaria children. Malaria diagnosis was carried out using microscopical examination of Leishman’s stained thick and thin blood films, P. falciparum parasitemia was assessed by standard microscopy techniques and complete blood count was done using Beckman Coulter Analyzer. Results: The body temperature on admission was significantly lower (p ˚C ± 0.07˚C) than in the three malaria groups. The mean body temperature of chloroquine treated children with malaria was significantly lower (p < 0.05) than that of children presenting with severe malaria. Parasitaemia was significantly lower (p < 0.05) in the pre admission chloroquine treated group (18.13% ± 0.49%) than in the non-treated simple malaria group (34.35% ± 2.75%) and severe malaria group (43.57% ± 5.49%), respectively. The average number of days before the cases were reported in the hospital was 4.80 days. The haemoglobin concentration of 7.23 ± 1.01 g/dl obtained for non-treated malaria patients indicates a mild anaemia, whereas the haemoglobin concentration values of 9.60 ± 0.51 g/dl and 10.52 ± 0.16 g/dl obtained for chloroquine treated children and control children respectively show that the two groups of children were not anaemic and the values obtained were within the normal range. Conclusion: The results obtained in this study demonstrate that there was significant positive impact of chloroquine treatment on Plasmodium falciparum parasitemia and degree of anemia in children under 5 years with Plasmodium falciparum in Jos Metropolis.

摘要： Anemia in a patient with cirrhosis is a clinically pertinent but often overlooked clinical entity.Relevant guidelines highlight the algorithmic approach of managing a patient of cirrhosis presenting with acute variceal hemorrhage but day-to-day management in hospital and out-patient raises multiple dilemmas:Whether anemia is a disease complication or a part of the disease spectrum?Should iron,folic acid,and vitamin B complex supplementation and nutritional advice,suffice in those who can perform tasks of daily living but have persistently low hemoglobin.How does one investigate and manage anemia due to multifactorial etiologies in the same patient:Acute or chronic blood loss because of portal hypertension and bone marrow aplasia secondary to hepatitis B or C viremia?To add to the clinician’s woes the prevalence of anemia increases with increasing disease severity.We thus aim to critically analyze the various pathophysiological mechanisms complicating anemia in a patient with cirrhosis with an emphasis on the diagnostic flowchart in such patients and proposed management protocols thereafter.

摘要： To protect from COVID-19 pandemic, several vaccines were developed infection with expected immunity against a SARS-CoV-2 infection. Short time side effects are reported. New onset diabetes was reported after SARS-CoV-2 infection. Here we report a case of new onset diabetes presenting with hyperosmolar hyperglycemic state, whose symptoms followed right after the second dose of Pfizer-BioNTech COVID-19 Vaccine. He is a 56-year old, obese Afro-American Veteran with no family history of diabetes and with HbA1C of 5.6 forty-five days prior to the hospitalization. He noted polyurea and excessive thirst following the second dose Pfizer-BioNTech COVID-19 vaccine. Hospitalized with hyperosmolar state and HbA1C of more than 14, he was treated initially with insulin drip and changed to basal, bolus regimen. In addition, he had new onset of oral thrush, requiring antifungal therapy. He needed higher doses of insulin during hospitalization and at discharge. He rapidly recovered and could be tapered off insulin in 4 months and recovered to normal glycemic state. We conclude that this is the second state to present with hyperosmolar state, and first case with rapid recovery of glycemic state.

摘要： Background: Heamatological problems have been associated with human immunodeficiency virus infection. Hypercoagulability, in particular, thrombosis is becoming more common in HIV-positive patients. Aim: The goals of this study were to determine levels of plasma fibrinogen, protein C, Hemoglobin, and ESR among Sudanese HIV-positive patients. Materials and Methods: This is a case-control study, for this investigation, a total of 100 participants were recruited for this study. Fifty people were diagnosed with HIV, 25 of whom were males (50 percent) and 25 of whom were females (50 percent), with an average age of 35.5 years. Further fifty healthy people, 26 (52%) of whom were men and 24 (48%) of whom were women, with a mean age of 37.1 years, matched the case group. Fresh Poor Plasma was obtained by centrifuging citrated venous blood samples at 3000 rpm for 15 minutes. The fibrinogen level was determined using an automated coagulation analyzer. Total protein C level was measured by a fully-automated blood coagulation analyzer (SYSMEX CA-500’JAPAN). The haemoglobin parameter was measured from EDTA anticoagulant samples using the Sysmex KX 21-N automated haematological analyzer. In one hour, the ESR was done using a Westergren tube. Data was collected using a structured direct questionnaire. SPSS version 21 was used to analyse the data. Results: The current study discovered that in Sudanese HIV infection, the mean and standard deviation of plasma fibrinogen levels were statistically substantially higher than in the normal control group (370.5 ± 67 vs 214.7 ± 21 with P value 0.001). Protein C levels were statistically significantly lower in HIV positive patients compared with control group (0.6 ± 0.1 vs 1.3 ± 0.2 with P value 0.001). In HIV positive patients, haemoglobin was statistically substantially lower than in healthy people (10.8 ± 1.8 vs 13.7 ± 1.9, P value 0.01). The erythrocyte sedimentation rate was statistically significantly higher in HIV positive patients than in the control group, with (58.00 ± 27 vs 7.68 ± 3 with P value 0.00). Conclusions: HIV infected patients had higher plasma fibrinogen levels and lower haemoglobin levels than normal healthy control groups. In 16 percent of HIV positive patients, protein C deficiency was discovered. HIV-positive patients had significantly greater ESR.

摘要： Background:Anemia is a common public health problem throughout the globe with its main effect not only on health of people but also impact on socioeconomic development.A high prevalence of anemia among school children is an indication of a severe problem highlighting the necessity of proper action to prevent further deterioration.This study sought to study the impact of nutritional education on knowledge,attitude,and practice regarding anemia among school children.Methods:This is an interventional study among school children of Kendriye Vidyalaya,No.2 Belgaum district,India.Structured and self-administered questionnaires were used to know the knowledge,attitude and practice of student anemia.The data were analyzed using paired t-test and McNemar test.Results:There was significant increment in the mean knowledge and attitude scores of the school children at the post-test evaluation.Overall increase of 51.2%in mean score of knowledge and overall increase of 20.7%in mean score of attitudes was found(P<0.05).Increase in frequency of consumption pattern of iron rich foods especially ragi,jaggery,green leafy vegetables and sprouted grains was reported.Conclusion:The nutritional education resulted in improvement of knowledge and change in attitude regarding anemia as well as increase in consumption of foods rich in Iron.Therefore,nutritional education is one of the cost-effective and sustainable method for lowering the cases of anemia.

摘要： Background: Undernutrition during pregnancy in the developing countries is a major public health problem due to its strong association with maternal and child morbidity and mortality. The available data on the extent and determinants of under-nutrition among pregnant women in Kenya is scant. This main objective of the study is to establish the extent and determinants of undernutrition in pregnant women attending a public hospital in Kenya. Methods: A cross-sectional study was conducted among 162 randomly selected pregnant women who attended antenatal clinic at Pumwani Maternity Hospital, a well-known public health facility in Nairobi. A semi-structured questionnaire was used to collect the data. Nutritional status of the pregnant mothers was determined using mid-upper arm circumference measurement. Hemoglobin level was extracted from the maternal antenatal card to determine their anemic status. Descriptive and inferential analyses were done using SPSS Software (version 22.0). Frequencies and proportions were generated for categorical variables. While mean and standard deviation were computed for continuous variables. The chi-square test of independence was employed to establish the relationship between the independent variables and dependent variable. Multivariable logistic regression analysis was used to identify the variables independently linked to maternal undernutrition. Results: The overall prevalence of undernutrition and anemia among the pregnant women was 27% and 39.7%, respectively. Multivariable logistic analysis showed that being single [AOR = 4.27;95% CI = 2.21 - 8.32, P = 0.001], divorced/separated [AOR = 2.25;95% CI = 1.13 - 4.87;P = 0.021], self-employed [AOR = 4.27;95% CI = 2.21 - 8.32;P = 0.022], illiterate [AOR = 4.31;95% CI = 2.55 - 8.20;P = 0.007), having short birth interval (<24 months) [AOR = 2.54;95% CI = 1.43 - 5.53;P = 0.042] and being anemic [AOR = 2.7;95% CI = 1.66 - 4.97;P = 0.037] were the variables significantly and independently associated with undernutrition among the pregnant women. Conclusions: Our findings show that the burden of undernutrition during pregnancy is still high in Kenya which requires urgent attention. Pregnant women who were never married, divorced/separated, self-employed, illiterate, and those with short birth interval were at increased risk of undernutrition. Nutrition intervention targeting social determinants of maternal undernutrition may result in positive outcomes. This will significantly help achieve the SDGs by reducing maternal child mortality.

摘要： Introduction: In low-income countries, severe anemia represents a significant risk of mortality. It is generally the consequence of a lack of correct community-based management of mild and moderate anemia and its etiologies. Our study aimed to evaluate the community practice in confronting anemia by mothers of children aged 0 - 5 years old before and during the COVID-19 period. Methods: We conducted a descriptive cross-sectional study in two phases at the pediatric ward of the regional hospital of Ngaoundere in Cameroon;before the period of the COVID-19 pandemic from December 2018 to May 2019 and during the pandemic period from December 2020 to May 2021. It was a volunteer sample. Were included in this study all mothers of children aged 0 - 5 years present in the pediatric ward at the time of the survey who agreed to freely answer our questionnaire. Results: Of the 152 mothers surveyed in the “Before COVID-19” group, 69% went to a health facility when they suspected their children were anemic, 20% gave grenadine juice (Red colored soda), 7% went to marabous, 2% bought street medicines and 2% used other home-made potions. Of the 92 mothers included in the “During COVID-19” group, the majority did not go to a health facility: 36% gave grenadine juice and other potions, 26% went to marabouts, 23% bought medicines from the street and only 13% went to a health facility;2% did nothing. The average Group rank is not statistically significantly different between the before and during the COVID-19 periods (p = 0.89). Conclusion: Community behavior and practice in confronting anemia deteriorated during the COVID-19 pandemic, with the majority of mothers resorting to non-effective out-of-hospital solutions. The consequence can be an increase in infant mortality. While waiting for the end of the pandemic, it is judicious and urgent to review the whole health system in Africa and especially in countries with limited resources. We propose developing multiple advanced strategies to promote community visits to prevent anemia and to develop anticipatory management of anemia as well as all the main child-killing pathologies.

摘要： BACKGROUNDMost cancer patients are accompanied by anemia, which will be more seriouswhen combined with end-stage renal disease (ESRD). At present, cancer-relatedanemia and renal anemia treatments mainly include erythropoiesis-stimulatingagents (ESAs), iron supplementation, and blood transfusion, but their effects areoften poor with several safety concerns. We have used roxadustat to treat anemiain a cancer patient with ESRD and achieved a successful outcome for the firsttime.CASE SUMMARYA 64-year-old man was diagnosed with right renal cancer (clear cell renal cellcarcinoma). He did not receive surgery or radiotherapy before admission. He wastreated with oral soltan (sunitinib malate) on April 18, 2017. During oral chemotherapy,he had numerous complications, including anemia, hypertension,thyroid hypofunction, skin pigment loss, and renal function deterioration. At last,he progressed to ESRD and began hemodialysis treatment. We initially treated thepatient with high-dose ESAs, iron supplementation, adequate dialysis, and evenblood transfusion, but his anemia did not improve. Roxadustat is a newlydeveloped drug for renal anemia treatment, but not for cancer-related anemia, letalone to treat anemia in cancer patients with ESRD. We prescribed oral roxadustatto the patient. After a period, his hemoglobin gradually increased. He did nothave obvious discomfort symptoms, and his tumor did not progress significantly.CONCLUSIONOral roxadustat could achieve good results in treating anemia in cancer patients with ESRD.
