Background. Volume of red cells in capillary blood varies from that of venous blood. The magnitude of this variation as well as its impact on the diagnosis of anaemia in pregnancy needs to be studied. This study demonstrates the disparity between capillary and venous PCV in pregnancy.Objectives. To determine whether capillary blood PCV (cPCV) differed from venous blood PCV (vPCV) of normal pregnant women in Enugu, Nigeria, and its effect on diagnosis and prevalence of anaemia.Methods. PCV was estimated using pairs of venous and capillary blood samples from 200 consecutive pregnant women at the Antenatal Clinic of University of Nigeria Teaching Hospital, Enugu, Nigeria.Results. Participants’ cPCV(median=34.0%,IQR=31.0–35.8)was significantly lower than their vPCV(median=34.0%,IQR=32.0–37.0)(Z=-6.85,P<0.001). However, women’s cPCV had strong positive correlation with their vPCV (r=0.883,P<0.001). The prevalence of anaemia among participants using capillary and venous blood was 33.5% (67/200) and 28.0% (56/200), respectively (O.R=1.3(CI 95%: 0.85, 1.98),  P=0.233).Conclusions. Capillary blood PCV was lower than vPCV among pregnant women in Enugu, Nigeria. Nevertheless, the prevalence of anaemia derived from cPCV did not differ significantly from that of vPCV.

Background: The use of clozapine demands regular monitoring of clozapine plasma concentrations and of white blood cell parameters. The delay between sending blood samples for analysis and receiving the results hinders clinical care. Point-of-care testing (POCT) can provide drug assay results within a few minutes. Aim: This study aimed to investigate the utility of a novel point-of-care device that can measure clozapine concentrations using capillary blood samples collected via a finger stick. Method: During a five-week period starting in June 2019 eligible patients were asked to provide a finger-stick capillary sample in addition to their usual venous blood sample. Samples were analysed by the novel point-of-care device and by the standard laboratory method. Capillary blood samples were tested by the MyCare™ Insite POCT analyser, and a quantitative measurement of clozapine concentration was provided within six minutes. Results: A total of 309 patients agreed to measurements by the two methods. Analysis revealed clozapine concentrations in venous blood as determined by the laboratory method ranged from 20 to 1310 ng/mL and by POCT from 7 to 1425 ng/mL. There was a strong positive correlation ( R = 0.89) between the results from the venous and the capillary sample methods. The slope of the association between standard assay and MyCare™ Insite was 1.0 with an intercept of –21 ng/mL, indicating minimal bias. Conclusion: Clozapine concentrations can be accurately measured at the point of care using capillary blood samples collected via a finger stick. This approach may be more acceptable than venous sampling to patients and, with almost instant results available, more useful to clinicians.

Background: Anaemia in pregnancy is a global health challenge. It is the commonest medical disorder of pregnancy and a major cause of morbidity and mortality in developing countries. Main cause of anaemia in obstetrics is iron deficiency. There are specific risks for the mother and the fetus such as intrauterine growth retardation, prematurity, and blood transfusion. Hence, the importance of giving iron in the antenatal period and to be continued postnatally. Objectives: The study was conducted to determine the overall prevalence of anaemia among pregnant women presenting in third trimester and its effect on pregnancy outcome. Methods: This is a cross sectional descriptive study done at National Medical College & Teaching Hospital from September 2015 to August 2016. During the study period 2048 pregnant women attended antenatal clinic in third trimester. Among 2048, 1200 were booked cases and out of these women with haemoglobin less than 11gm/dl were labeled as anaemia. The prevalence was calculated along with the maternal and fetal outcome. Result: Among 2048, 1200 were booked cases, 368 (30.66%) were anemic, 66.30% were multigravida, 67.93% in age group of 21-30 years, 284 patients came for delivery. In 14.08% patients there was preterm labour, apgar score less than 7 in 66.19% babies. Majority of neonate weighed between 2.0 - 2.5kg (49.29%). Perinatal deaths were 2.81%. Conclusion: Anaemia in pregnancy need awareness about early and regular antenatal care with oral iron supplementation. Correction of anaemia will reduce the maternal and fetal complications.

To determine the precision and agreement of the hemoglobin (Hb) measurements in capillary and venous blood samples by the HemoCue® and an automated counter. Hb was determined by both equipaments in blood samples of 29 pregnant women. The HemoCue® showed low repeatability of Hb measurements in duplicate in capillary (CR=0.53 g/dL, CV=13.6%) and venous blood (CR=0.53 g/dL, CV=13.6%). Hb measurements in capillary blood were higher than those in venous blood (12.4 and 11.7 g/dL, respectively; p<0.05). There was high agreement between Hb in capillary blood by the HemoCue® and in venous blood by the counter (r icc=0.86; p<0.01), and also between the diagnosis of anemia by both equipments (k=0.81; p<0.01). The HemoCue® seems to be more appropriate for capillary blood and require training of the measurers.

Background: Anemia is regarded as a major risk factor for unfavorable outcome of pregnancy both for the mother and the fetus. Maternal anaemia is a common problem in pregnancy, particularly in developing countries.Aims: To determine the prevalence of anaemia in pregnancy and to find out the haemoglobin level of pregnant women reporting for antenatal checkup among the women reporting for antenatal care in Combined Military Hospital Dhaka.Method: This is a descriptive cross sectional study was done in the antenatal clinic at CMH Dhaka. One eighty four (184) pregnant women attending antenatal clinic at CMH Dhaka including CWC under CMH Dhaka were included for the study. The data were collected from 1st May 2001 to 31st May 2001 at the antenatal clinic, combined Military Hospital. Dhaka where pregnant women reported for antenatal check up. The data were collected by interviewing respondents in different dates & day of the week at different CWC and CMI-I Dhaka. Prior to the interview the respondents were explained clearly the objective of the study and sought their co-operation. The authority of CMH Dhaka was given prior information through issuing letter from AFMI. The respondent was assured on ethical point of view that strict secrecy would be maintained. Data were collected by the following methods: Interview Method; Laboratory Investigation for Hb estimation and Scrutinization of antenatal check up card.Results: A total of 184 pregnant women of them 70 were primi gravida and 114 were multigravida. The prevalence of anaemia as per WHO cutoff points was 56.52% (<11.0 g/dl). The mean age was 24.96 ± 4.49 years. The age groups 20-24 was the maximum. Out of 184 women 104 women was ariaemic. 15-24 age group was more anaemic (57.42%) than the 25-39 age group (55.42%) but the difference was not statistically significant, P>0.05. The prevalence of anaemia was higher in Illiterate (100%), lowest in degree and above level education group (48.48%). The maximum women (64.13%) belong to lowest income group. (Tk 2500-5000) Anaemia was the most common in the lowest income group (60.50%). The prevalence of anaemia was the highest among the family size 6 and above group (75%) and lowest in 2-3 family size group. Anaemia was more prevalent among high parity group (75%) and lowest in ‘0’ parity group (52.28%) but the difference was not statistically significant (P > 0.05). Multigravida were found more anaemic (62.28%) contrast to prirnigravida (47.14%) which was statistically significant (P<0.05). The prevalence of anaemia was less in higher birth interval group but the difference was not statistically significant (P>0.05). About the cultural belief only 33 women were found having cultural belief of avoiding food during pregnancy (17.93%) and anaemia was more prevalent among them (57.57%) but the difference was statistically significant (P>.05). In this study 14.13% women had concomitant illness during pregnancy. In this study 15 women had caesarian section of which 10 were anaemic (75%) and there was one Forcep delivery (non-anaemic).Conclusion: In this study anaemia is more prevalent among younger age group women (15-24), with less educated group low income group, large family size group, high parity and high gravida, less birth spacing and also in women having concomitant illness. Anaemia is more prevalent among women having cultural belief on avoiding food during pregnancy. The findings of this study may not reflect the overall picture of the country. It does not differ much from the results of similar studies at national level. However, this study can be a base for further studies in a broader perspective.J Dhaka Medical College, Vol. 26, No.2, October, 2017, Page 103-110

Abstract Background Both capillary and venous blood samples have been interchangeably used for the diagnosis of malaria in Ethiopia. However, Plasmodium parasites are thought to be more concentrated in capillary than in venous blood. Hence, selecting a sample source where parasites are more concentrated is indispensable approach in order to maximize the accuracy of blood film microscopy. Therefore, the present study aimed to compare the detection rate and the parasitemia level of Plasmodium species from conventional capillary and venous blood films, and buffy coat preparations. Methods A facility based cross-sectional study was conducted from Feburary to March 2020 among 210 febrile patients attending Hamusite health center, northwest Ethiopia. Capillary and venous blood samples were collected and buffy coat was prepared from each sample. Thin and thick blood films were prepared, stained, and examined microscopically following standard protocol. Data were analysed using Statistical Package for Social Sciences Software version 20 and Med-Calc software version 19.3. Results Capillary blood buffy coat (61/210, 29.0%) had significantly higher detection rate as compared to capillary (48/210, 22.9%) and venous (42/210, 20.0%) blood films (p < 0.001). However, no significant difference was observed between capillary and venous blood films (p = 0.070) in detecting Plasmodium species. The highest and the lowest mean asexual stage parasite counts were found in capillary blood buffy coat (4692.88) and venous blood (631.43) films, respectively showing significant variations (p < 0.001). Mean gametocyte count was also highest in capillary blood buffy coat (3958.44). As compared to capillary blood buffy coat, the sensitivity of venous blood buffy coat, capillary blood film and venous blood film were 73.8, 78.7, 68.9%, respectively. Conclusion Capillary blood buffy coat samples showed the highest sensitivity in detecting and quantitating malaria parasites that its use should be promoted in clinical settings. However, conventional capillary and venous blood films could be used interchangeably.

The purpose of this study is to compare whether or not there is a difference between venous and capillary blood samples in blood glucose measurements and investigate the effects of different aseptic methods used in skin cleaning before collecting blood samples on measurement results. This quasi-experimental study was conducted with 109 patients. The capillary first and second blood drop values taken from the patients after fasting and at 2 hours following 75 g oral glucose tolerance test (OGTT) and capillary and venous blood glucose values were compared. There was no significant difference between the median venous blood glucose value and the capillary second blood drop value taken after wiping the finger with alcohol. There was no significant difference between the first and second blood drop values of capillary blood glucose 2 hours after OGTT.

The ‘Dextrostix’-reflectance meter system for blood glucose analysis has been evaluated using a blood glucose reference method. A high degree of concordance between the two methods was obtained when analyses were performed by skilled laboratory staff on venous blood samples containing fluoride, with a 75 s contact time. Skilled laboratory staff performed significantly better than unskilled staff. Capillary blood glucose concentrations correlated poorly with concentrations in venous blood samples taken at the same time as the capillary blood.

Abstract Background The Sustainable development goals, which focus strongly on equity, aim to end all forms of malnutrition by 2030. However, a significant cause of intergenerational transfer of malnutrition, anaemia in pregnancy, is still a challenge. It is especially so in the low- and middle-income settings where possible context-specific aetiologies leading to anaemia have been poorly explored. This study explores the prevalence of etiological factors significantly contributing to anaemia in pregnancy in Sri Lanka, a lower-middle-income country with a high prevalence of malnutrition albeit robust public health infrastructure. Methods All first-trimester pregnant women registered in the public maternal care programme in the Anuradhapura district from July to September 2019 were invited to participate in Rajarata Pregnancy Cohort (RaPCo). After a full blood count analysis, high-performance liquid chromatography, peripheral blood film examination, serum B12 and folate levels were performed in anaemic participants, guided by an algorithm based on the red cell indices in the full blood count. In addition, serum ferritin was tested in a random subsample of 213 participants. Anaemic women in this subsample underwent B12 and folate testing. Results Among 3127 participants, 14.4% (95%CI 13.2–15.7, n = 451) were anaemic. Haemoglobin ranged between 7.4 to 19.6 g/dl. 331(10.6%) had mild anaemia. Haemoglobin ≥13 g/dl was observed in 39(12.7%). Microcytic, normochromic-normocytic, hypochromic-normocytic and macrocytic anaemia was observed in 243(54%), 114(25.3%), 80(17.8%) and two (0.4%) of full blood counts in anaemic women, respectively. Microcytic anaemia with a red cell count ≥5 * 106 /μl demonstrated a 100% positive predictive value for minor haemoglobinopathies. Minor hemoglobinopathies were present in at least 23.3%(n = 105) of anaemic pregnant women. Prevalence of iron deficiency, B12 deficiency and Southeast Asian ovalocytosis among the anaemic was 41.9% (95%CI 26.4–59.2), 23.8% (95%CI 10.6–45.1) and 0.9% (95%CI 0.3–2.3%), respectively. Folate deficiency was not observed. Conclusion Even though iron deficiency remains the primary cause, minor hemoglobinopathies, B 12 deficiency and other aetiologies substantially contribute to anaemia in pregnancy in this study population. Public health interventions, including screening for minor hemoglobinopathies and multiple micronutrient supplementation in pregnancy, should be considered in the national programme for areas where these problems have been identified.

Background: Anaemia in pregnancy, which can lead to adverse maternal and fetal outcomes, is a significant global health problem. Despite Sri Lanka’s strong public health system and commitment towards prevention, maternal anaemia remains a major problem in the country. While prevention is focused on iron deficiency, detailed etiological studies on this topic are scarce. Moreover, estimates of socio demographic and economic factors associated with anaemia in pregnancy, which can provide important clues for anaemia control, are also lacking. This study aims to evaluate the hemoglobin distribution, spatial distribution, etiology and associated factors for anaemia in pregnant women in Anuradhapura, Sri Lanka. Methods: This is a cross sectional study of pregnant women in their first trimester registered for antenatal care from July to September 2019 in the Anuradhapura district. The minimal sample size was calculated to be 1866. Initial data collection has already been carried out in special field clinics for pregnant women between June to October 2019. An interviewer-administered questionnaire, a self-completed dietary questionnaire and an examination checklist were used for data collection. In addition, all participants underwent complete blood count testing. Further investigations are being conducted for predicting the etiology of anaemia based on a developed algorithm (such as high-performance liquid chromatography [HPLC] and peripheral blood film analysis). Discussion: Being the largest study on anaemia during pregnancy in a single geographical area in Sri Lanka, this study will provide important clues about geographical clustering of anaemia cases with similar etiology, associated factors and etiologies which would help to develop interventions to improve the health of pregnant women in the area. The possibility of selection bias is a potential limitation associated with the study design.

Objective: Malaria is a major cause of indirect maternal death. In the last two decades several efforts have been made to combat the menace of this disease especially among pregnant women and children in developing countries. Directly observed therapy (DOT) was recommended to enhance the uptake of intermittent preventive treatment (IPT) of malaria with sulfadoxine – pyrimethamine among pregnant women. Due to challenges involved in the practice of DOT especially with regards to shortage of man power and clean water in rural areas, there is need to evaluate impact of DOT on the effectiveness of treatment. Material and Methods: A cohort study was carried out among 320 healthy pregnant women receiving ante natal care with equal assignment of subjects. The study group (160) received two doses of IPT by DOT while 160 matched controls were given prescription for self- drug administration at home. Malaria tests were done using microscopy method and the hemoglobin values determined using centrifuge one month after the second dose of IPT. Umbilical cord blood samples were obtained for a repeat microscopy at delivery. Results: The results showed that there were no statistical significant differences in the venous blood parasitemia, placental parasitemia and anaemia between the DOT group and the control group (P = 0.215; P = 0.100; P = 0.966) respectively. Lower social class was the main predictor of anaemia in pregnancy (P = 0.032). Conclusion: The delivery of IPT through DOT may not influence uptake in some settings. Effort may need to be channeled into ante natal education and women empowerment.
