In the absence of breast milk,...Breast milk offers essential nutrients crucial for the development of the preterm immune system, thus reducing the incidence of infection and mortality often associated with prematurity. In the absence of breast milk, the preferred option is donated breast milk, the best alternative for hospitalized neonates whose mothers have insufficient breast milk or are unavailable. In Zambia, donor breast milk is unavailable. Instead, the protocol recommends the administration of formula milk. However, the use of formula milk in preterm babies is associated with an increased risk of necrotizing enterocolitis and sepsis. Zambia needs to establish a donor milk bank, hence the need to understand the perception of mothers towards donated breast milk. A qualitative descriptive case study utilized 10 focus group discussions with in-depth interviews, purposively selected using a variation strategy. Data was thematically analysed. Participants demonstrated potential acceptance to donor breast milk utilization, as more nutritional compared to formula despite lack of awareness. Concerns related to safety, quality, fear of disease transmission and discomfort feeding from a different bloodline were identified as hinderance to possible utilisation. These perceptions underscore the importance of educational initiatives aimed at dispelling myths and misconceptions surrounding donor breast milk and establishing donor breast milk programs. Therefore, the study recommends educational initiatives tailored to raise awareness to mothers about donor breast milk.展开更多

Globally, ...Background: Kangaroo Mother Care is a simple safe method used to care for low-birth-weight babies. Low-birth-weight is a global public health issue that pose significant challenge to perinatal care systems. Globally, complications due to low-birth-weight are the leading cause of neonatal mortality, resulting in an estimated 1 million deaths annually. Kangaroo Mother Care (KMC) is a low-cost method of care for low-birth-weight infants in areas with inadequate incubators and power outages with positive outcomes. Objectives: To assess factors influencing acceptability of Kangaroo Mother Care (KMC) in NICU at Arthur Davison Children’s Hospital in Ndola, Zambia. Methodology: A cross sectional quantitative analytical study design was used. The study was conducted at Arthur Davison Children’s Hospital (ADCH) in Ndola, Zambia. The purposive sampling method was used to select the study participants and a total of 129 mothers with Low Weight Babies A were selected to participate structured closed ended questionnaire was used to collect data from the participants using an interview. Data was analyzed using a Statistical Package for Social Scientists (SPSS) software version 26. Cross tabulations were done to determine association of variables using a Chi square (x<sup>2</sup>) test at 95% confidence interval and were assumptions where not met, fishers exact test was used. Multivariate binary logistic regression analysis was used to quantify the relationship between the dependent and independent variables. Results: Most of the respondents had male babies 77%, 69% of the babies weighed 1000 g - 1400 g, majority 79% had normal delivery, 71% of the respondents were multigravida and most of the respondents 79% were married. The study reviewed that 85% of those who attained secondary education accepted KMC, 74% of the respondents without monthly income accepted KMC, 80% of the respondents had positive attitude and accepted KMC. 82% of the respondents who had positive perception accepted KMC. Conclusion: Acceptance of Kangaroo Mother Care (KMC) among 75% of the mothers underscores its widespread favourability as a beneficial method for infant care.展开更多

The major serious complications of prematurity include bronchopulmonary dysplasia, with lesser incidences of retinopathy of prematurity, intraventricular haemorrhage, and necrotising enterocolitis. Many studies have shown correlations between the receipt of blood transfusions and the development of these conditions, but little is known of the underlying pathophysiology of this relationship. Recent studies are beginning to provide some answers. This review examines recent findings with regard to the influence of preparation and storage of paediatric packed red blood cell units on heme, iron, and oxidative status of the units and relates these to the ability of the premature baby to deal with these changes following the receipt of blood transfusions. Paediatric packed red blood cell units are a potential source of heme, redox active iron and free radicals, and this increases with storage age. Haemolysis of transfused red blood cells may add further iron and cell free haemoglobin to the recipient baby. Premature babies, particularly those with low birth weight and gestational age appear to have littlereserve to cope with any additional iron, heme and/or oxidative load. The consequences of these events are discussed with regard to their contribution to the major complications of prematurity and a novel hypothesis regarding transfusion-related morbidity in premature babies is presented. The review concludes with a discussion of potential means of limiting transfusion related iron/heme and oxidative load through the preparation and storage of packed red blood cell units and through modifications in clinical practice.展开更多

[ Method] Fifty-four Angora female rabbits with similar body weight, parities and historicaly hair yield were randomly assigned to three groups with eighteen replicates in each group and one rabbit per replicate. Rabbits during pregnancy were fed diets with 0.5!%, 0.71% and 0.91% methionine, respectively. Hair follicle density and diameter in the back skin were determined at 18-day fetus. 26-day fetus, newborn and 2- month-old,and hair fiber diameter at 2-month-old was also determined. [ Result] The results showed as follows： （1） hair follicle density and diameter at each stage,coarse hair fiber diameter at 2-month. old showed a tendency of increasing with dietary methionine level（ P 〉0.05）, fine hair diameter in 0.91% group was significantly larger than that in 0.51% group at 2-month-old （ P 〈 0.05）. （2） With the development of baby rabbit,the ratio of secondary follicle and primary follicle increased gradually, at newborn of rabbits in group 0.51%, 0.71% and 0.91%were 5.84, 5.56 and 5.81, respectively, and at 2-month-old were 8.47, 7.97 and 8.03, respectively. （3） Baby rabbits in group 0.51%, 0.71% and 0.91% gained increases of primary follicle diameter by 0.58, 0.57 and 0.61pm/d from 26-day fetus to birth, and 0.11,0.11 and 0.12 prn/d from birth to 2-month-old, re- spectively; they also gained increases on secondary follicle diameter by 0.0018,0. 012 and 0. 011prn/d from birth to 2-months-old, respectively. [ Conclusion] These results indicate that increase of methionine level in diet for female rabbits during pregnancy is a stimulation factor for the development of hair follicle of baby rabbits, and can improve their hair fiber diameter.展开更多

METHODS: In the study period from January 2007 to February 2010, 76 consecutive patients(33 men, 43 women; mean age 63 years old) were included in this pilot series. Endoluminal images and biopsies were obtained from 55 patients with indeterminate strictures, while 21 patients had fixed filling defects. The diagnostic accuracy of peroral cholangioscopy(POCS) in the visualization of strictures and tissue sampling was evaluated, and therapeutic success was monitored. Followup was performed over at least 9 mo. RESULTS: A total of 55 patients had indeterminate strictures. Using the criteria "circular stenosis" and "irregular surface or margins", POCS correctly described 27 out of 28 malignant biliary strictures and 25 out of 27 benign lesions(sensitivity, 96.4%; specificity, 92.6%, diagnostic accuracy 94.5%). Visually targeted forceps biopsies were performed in 55 patients. Tissue sampling during POCS revealed malignancy in 18 of 28 cases(sensitivity: 64.3%). In 21 patients with fixed filling defects, 10 patients with bile duct stones were successfully treated with conventional stone removal. Nine patients with difficult stones(5 giant stones and 4 intrahepatic stones) were treated with visually guided laser lithotripsy. Two patients in the group with unclear fixed filling defects had bile duct adenoma or papillary tumors and were surgically treated. CONCLUSION: The new 95 cm POCS allows for accurate discrimination of strictures and fixed filling defects in the biliary tree, provides improved sensitivity of endoscopically guided biopsies and permits therapeutic approaches for difficult intrahepatic stones.展开更多
