Development and Evaluation of 3D Delivery Animation Software Designed to Improve the Mother’s and Spouse’s Satisfaction with Delivery

Purpose: To clarify the effectiveness of 3-D delivery animation software for the mother’s and husband’s satisfaction with delivery. Subjects and Method: We independently developed a software application used to display the pelvic region and explain the labor process. The study involved a collaboration with hospital staff who recruited 18 primiparous and 18 multiparous mothers who were hospitalized for delivery at Facility A. The midwife explained the process of delivery using the “Delivery Animation Software”. A self-administered, anonymous questionnaire was distributed and analyzed separately for primiparous and multiparous mothers and their husbands. Results: 1) For both primiparous and multiparous couples, both mothers and their husbands gained a significantly higher level of understanding after delivery than during pregnancy. 2) The Self-Evaluation Scale for Experience of Delivery results were as follows: “I did my best for the baby even if it was painful” was selected more often for “birth coping skills”;“reliable medical staff” was selected more often for “physiological birth process”;“the birth progressed as I expected” was selected frequently by primiparous mothers;and “the birth progressed smoothly” was selected often by multiparous mothers. 3) In terms of husbands’ satisfaction with the delivery, “I was satisfied with the delivery”, “I was given an easy-to-understand explanation”, and “They explained the process to me” was selected of primiparous and multiparous fathers. 4) All primiparous and multiparous mothers positively evaluated whether the delivery animation was helpful in understanding the process of delivery. Conclusion: The delivery animation was effective in improving the understanding and satisfaction of both the mothers and their husbands.

Lacticaseibacillus rhamnosus Probio-M9 may be vertically transmitted from mother to infant during lactation based on faeces metagenomics

Probiotics exert beneficial effects on the host.This study aimed to investigate whether maternally ingested Lacticaseibacillus rhamnosus Probio-M9 during pregnancy could access and colonize the infant gut.This study recruited one pregnant woman,who ingested Probio-M9 daily from 35 weeks of gestation to delivery.Feces of the mother-infant pair were regularly collected from one month before delivery to 6 months of infant's age for metagenomic sequencing.Probio-M9 genomes were mappable to all infant fecal samples,suggesting the ingested probiotics could be vertically transmitted from mother to infant.Infant-or mother-specific differential metabolic pathways were found between the maternal and infant's gut microbiome,implicating apparent differences in the intestinal metagenomic potential/function between the mother and the infant.In conclusion,maternal ingestion of Probio-M9 during the final weeks of gestation could deliver to the infant gut.The findings provided novel insights into shaping infant's gut microbiota.

Effect of a Nutrition Education Intervention on Food Safety Knowledge, Attitudes and Practices of Mothers of Children under 5 Years in the Peri-Urban Areas of Bobo-Dioulasso: Before and after Study

Background: This study assessed the effect of a nutrition education intervention. This intervention aimed to improve the knowledge, attitudes, and practices of mothers on food safety in the peri-urban areas of Bobo-Dioulasso in Burkina Faso. Methods: A total of 243 mothers of children under 5 years in the peri-urban of Bobo-Dioulasso were administered the FAO questionnaire for food safety knowledge, attitudes, and practices assessment during two cross-sectional surveys, before and after the intervention, in January and October 2017. The intervention included two components consisting of a theoretical phase (counselling and discussion) and cooking demonstrations implemented for ten months. To account for the before-and-after design of the study, the McNemar’s test was used to assess the effect of the intervention on food safety KAP of mothers of children under 5 years. Results: The mean age of mothers was 29 ± 6.2 years and 50.6% of them were between 20 and 29 years old. One for knowledge (cooking thoroughly with, p-value = 0.0001) and another for attitudes (perceived benefits of reheating leftovers before eating them, p-value = 0.0001), significantly increased after the intervention. In terms of food safety practices, all the indicators (cleaning of dirty surfaces, plates and utensils and storage of perishable foods) significantly increased (all p = 0.0001 Conclusion: This study provided some evidence of an effective nutrition education intervention for improving maternal KAP on food safety for their child’s feeding.

Acceptability of Kangaroo Mother Care (KMC) by Mothers with Low-Birth-Weight Babies at Arthur Davison Children’s Hospital, in Ndola, Zambia

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 (x2) 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.

Mother-to-Child Transmission of Human Papillomavirus in Burkina Faso

Introduction: Human papillomavirus (HPV) infection is the most widespread sexually transmitted infection in the world. Today, there is growing evidence that HPV can be transmitted early in life, and one potential route is mother-to-child transmission. Data on this route of HPV transmission are scarce in Africa and particularly in Burkina Faso, where no data on the subject are yet available. The aim of our study was to estimate the rate of mother-to-child transmission of HPV infection and to identify circulating genotypes. Methodology: Cervico-uterine samples were collected from 100 full-term pregnant women and, buccal samples were obtained from their newborns at Hopital Saint Camille de Ouagadougou (HOSCO) by the specialist physician. HPV DNA amplification and genotyping were performed by PCR followed by hybridization using the HPV Direct Flow Chips kit, detecting 36 genotypes including 18 high-risk and 18 low-risk. Results: The prevalence of HPV in newborns was 8% (8/100). Six (6) HPV-positive neonates had HPV-positive mothers, while 2 HPV-positive neonates had HPV-negative mothers. The vertical transmission rate was 26.09% (6/23). Mother-newborn genotypes were concordant. However, the genotype profile of the newborns was more restricted than that of the mothers. Conclusion: HPV DNA was found in 8% of newborns in our study. The genotype profile of the mother-newborn pair was concordant. Asymptomatic HPV infection in a pregnant woman could constitute a risk factor for vertical transmission.

Evolution of Mother-to-Child HIV-1 Transmission Rate in Mali from 2009 to 2018

Despite enormous efforts to achieve the goal of eliminating mother-to-child transmission of HIV-1, it remains a major challenge for many countries in sub-Saharan Africa, particularly Mali. Our objective is to assess changes in the rate of mother-to-child transmission of HIV-1. We conducted a cross-sectional study between January 1, 2009 to December 31, 2018 (10 years) of early diagnosis activity in newborns and children born to HIV-1-positive mothers at the National Institute for Public Health (INSP). The samples came from health and referral centers in mali. All samples were received at the Laboratory of Molecular Biology at the INSP. Proviral DNA extraction was performed from a blood spot sample with a Roche DNA kit, Cobas AmpliPrep/Cobas TaqMan HIV-1 qualitative Test, V2.0 (Roche Molecular System, Inc, USA) following the company procedures. Molecular diagnosis was performed using the same kits using an algorithm of three identical PCRs. The Epi Info version 7 software was used for data analysis with a significance threshold of 5%. A total of 10,714 samples of infants and children born to HIV-positive mothers were analyzed by PCR. Ninety-six percent of mothers were on ARV prophylaxis (AZT 3TC NVP and AZT NVP) and 60% of newborns received the same ARV prophylaxis. Of these children, 956 tested positive with an overall transmission rate of 8.92%, varying between 7.27% in 2009 and 08.01% in 2018. This rate was relatively low among children receiving prophylaxis at 2.04% and remained high for children who received breastfeeding at 5.62%. However, the transmission rate remains low for those who have benefited from mixed and artificial breastfeeding at 1.58% and 1.27% respectively. A significant proportion of children remained infected by their mothers during pregnancy, childbirth or breastfeeding. This study shows the importance of early diagnosis of HIV in children using molecular technology.

Experiences of Mothers on the Utilization of Elimination of Mother to Child Transmission of HIV Services at Mtendere Clinic, Lusaka

Introduction: Acquired immunodeficiency syndrome is one of the leading causes of mortality among women of reproductive age and Mother to Child Transmission of Human immunodeficiency virus is still a challenge affecting many countries. Globally, an estimation of 180,000 children under 15 years acquire the Human immunodeficiency virus every day, and more than 90% of those infections are due to Mother to Child Transmission. The study sought to explore the experiences of mothers on the Elimination of Mother to Child Transmission-HIV services at Mtendere Clinic, Lusaka. Materials and Methods: Qualitative interpretive phenomenology study design was employed using in-depth interviews to collect data from a sample that was selected using purposive sampling technique. Thirteen participants were recruited, and these were HIV-positive mothers at least between the ages of 15 and 49 years and enrolled in the Elimination of Mother To Child Transmission-HIV program. The in-depth interviews were audiotape recorded and transcribed verbatim. Data was analyzed using thematic method. Findings: Three main themes that emerged are;living with HIV, support system and barriers to utilization of Elimination of Mother To Child Transmission-HIV services. Most of the participants expressed having acquired knowledge from the program, and received counselling and support from spouses, family as well as health personnel at Mtendere health facility which culminated into a positive experience and enhanced their uptake of the Elimination of Mother to Child Transmission-HIV services. However, barriers to service utilization were identified and these included fear of stigma, negative attitudes from health workers, long waiting times, lack of support and lack of transport to the health facility. Conclusion: Interventions such as community awareness campaigns on Elimination of Mother To Child Transmission-HIV, male involvement and implementing mother-to-mother peer support strategies in Elimination of Mother To Child Transmission-HIV service utilization should be prioritized so as to alleviate stigma and enhancing a positive experience for these mothers thus reducing on the Mother to Child HIV Transmission burden and mortality rates.

Percutaneous Coronary Intervention in Acute Coronary Syndromes at the Mother-Child University Hospital Luxembourg in Bamako

Introduction: Acute coronary syndromes (ACS) are a diagnostic and therapeutic emergency. Objective: Studying the feasibility, difficulties and results of coronary angioplasty in acute coronary syndromes at the Luxembourg Mother-Child University Hospital in Bamako. Patients and Methods: Cross-sectional, descriptive study with prospective recruitment over 18 months from September 2020 to February 2022. All patients aged at least 18 years old admitted for SCA and having undergone PCI during the study period were included. Result: We collected 249 patients for SCA, of whom 160 underwent angioplasty, either an angioplasty/SCA ratio of 0.64. The average age of the patients was 59.54 ± 11.62 with extremes of 32 and 92 years. The age group of 45 to 65 years was the most representative. The predominance was male, sex ratio of 2.4. The main cardiovascular risk factors were high blood pressure (58.23%) and diabetes (45.78%). Persistent ST-segment elevation on the electrocardiogram was present in 71.48%. The treatment time was more than 12 hours after the first medical contact in 95.5%. The approach was radial in 96.5% of cases. Coronarography was pathological in 91.16% of our patients. The lesions were tri-truncular in 34.13% with the anterior inter ventricular as culprit artery in 72% of cases. The majority of patients (64%) had undergone angioplasty with implantation of an active stent. Angioplasty was performed successfully in 98% and per procedural mortality was 1.87%. Only 6.45% of ACS with ST elevation benefited from primary angioplasty. Conclusion: Percutaneous coronary intervention is performed routinely in our center with satisfactory results. Difficulties exist, related to the diagnostic delay of ACS and the high cost of angioplasty.

Cardiometabolic effects of breastfeeding on infants of diabetic mothers

BACKGROUND Breast milk is the best and principal nutritional source for neonates and infants.It may protect infants against many metabolic diseases,predominantly obesity and type 2 diabetes.Diabetes mellitus(DM)is a chronic metabolic and microvascular disease that affects all the body systems and all ages from intrauterine life to late adulthood.Breastfeeding protects against infant mortality and diseases,such as necrotizing enterocolitis,diarrhoea,respiratory infections,viral and bacterial infection,eczema,allergic rhinitis,asthma,food allergies,malocclusion,dental caries,Crohn's disease,and ulcerative colitis.It also protects against obesity and insulin resistance and increases intelligence and mental development.Gestational diabetes has short and long-term impacts on infants of diabetic mothers(IDM).Breast milk composition changes in mothers with gestational diabetes.AIM To investigate the beneficial or detrimental effects of breastfeeding on the cardiometabolic health of IDM and their mothers.METHODS We performed a database search on different engines and a thorough literature review and included 121 research published in English between January 2000 and December 15,2022,in this review.RESULTS Most of the literature agreed on the beneficial effects of breast milk for both the mother and the infant in the short and long terms.Breastfeeding protects mothers with gestational diabetes against obesity and type 2 DM.Despite some evidence of the protective effects of breastfeeding on IDM in the short and long term,the evidence is not strong enough due to the presence of many confounding factors and a lack of sufficient studies.CONCLUSION We need more comprehensive research to prove these effects.Despite many obstacles that may enface mothers with gestational diabetes to start and maintain breastfeeding,every effort should be made to encourage them to breastfeed.

Umbilical Cord Care Practices and Cord Care Education of Mothers Attending Health Care (Pakistan Prospect)

Neonatal mortality is of global concern, it is the death in the first month of life. According to WHO, 2.4 million children died globally in the first month of life2. Globally the neonatal mortality rate declined slowly from 28/100 live births in 2000 to 17.9/100 live births in 2019. It is a major challenge for the low socioeconomic group of countries. Most neonatal deaths occurred in south Asia and African countries, in 2019 out of 2.4 million death 81% occurred in the Southeast Asia. Objective: To evaluate and improve cord care practices of mothers to reduce the risk of cord related infections. Methodology: The mixed method will be used in this research, questionnaire is used for data collection, total collected sample is 391. Results: 354 (91.0%) of the 394 patients analyzed obtained prenatal care (ANC) in both traditional and nontraditional settings. Among these, 288 (72.3%) got cord care health education, whereas 106 (27.7%) did not. The overall documentation of the instructions for the use of metabolized spirits alone included 116 (48.9%) teaching institutions and 103 (43.5%) private hospitals. the average results show the age of the baby 1 - 7 days, the average age of the mother is 18 - 25 years. The average education of the mothers is primary. Participation of health centers is average. Most of the participants has 1 child. Conclusion: This research concludes the poor umbilical cord practices and knowledge. Those with information used it better. Raise awareness about umbilical cord care and improper behaviors, including using mentholated balms. Before women leave the hospital, they should learn cord care. Mothers must clean wires. Several healthcare organizations don’t provide cord care instruction, and what they provide isn’t research-based.

Mothers’ Level of Schooling, Monitoring of Their Pregnancy and Perinatal Prognosis at the Reference Health Centre of Commune V of the District of Bamako

Introduction: The level of schooling of mothers is a determining factor in the follow-up of pregnancy and consequently the prognosis of childbirth and the quality of the newborn. Objective: The aim was to assess the impact of the level of education on the follow-up of their pregnancy and perinatal prognosis at the Reference Health Centre of Commune V of the District of Bamako. Materials and Methods: This was a prospective, cross-sectional and analytical study aimed descriptive from August 15 to December 15, 2021. We included in this study all pregnant women who had a gestational age of at least 22 weeks of amenorrhea and who gave birth or were received in the immediate postpartum period at the maternity ward of the Reference Health Center of Commune V. Results: Out-of-school parturients accounted for 60% of cases. Among the parturients in school, 18% had a higher level. In our study, 14.3% of women in labour knew the date of the last menstrual period. In our series, 100% of mothers in higher and secondary school had completed an antenatal consultation (CPN) compared to 90.7% in the out-of-school mothers. CPN1 was performed in the first trimester of pregnancy in 21.1% among out-of-school parturients compared to 83.5% among higher-level parturients. The number of NPCs was greater than or equal to 4 in 47.9% of parturients. Conclusion: Women’s schooling has an impact on their socio-economic conditions on the one hand and on the monitoring and prognosis of pregnancies on the other.

Mother’s Nutritional Knowledge and Practice towards Children under Two Years of Age and Its Impact on Their Health in Abuzaid Albuluk Pediatric Specialized Hospital in 2023

Background: Nutritional knowledge and practise is an important measure to improve dietary habits and food choices. The daily food should contain balanced nutrition as needed to support optimal growth, avoid deficiency diseases and prevent the diseases which might interfere with the children health. Materials & Methods: A descriptive cross-sectional non-interventional hospital-based study was carried out among 122 mothers and 122 children by using a non-probability convenience sampling technique in the period of 15 March to 15 April 2023, and using interviews with structural questionnaires, the data was analyzed using SPSS version 26. Results: We found that most of the children had moderate health, while most of the mothers had moderate nutritional knowledge and practise towards their children, also we found that the relationship between mothers’ knowledge and practise and child health was significant (P Conclusion: Mothers’ knowledge and practise among children was moderate and children had moderate health. Wrong beliefs and cultural taboos play major roles in decreasing knowledge and practise.

Early Morbidity and Mortality in Neonates of Mothers with Sickle Cell Disease at the Borgou/Alibori Center Departmental Teaching Hospital in Benin

Introduction: Association of sickle cell disease and pregnancy is a risky situation for both the mother and neonate. Objective: To determine the early morbidity and mortality among neonates of mothers with sickle cell disease at Borgou/Alibori Center Departmental Teaching Hospital (CHUD B/A) in Benin. Patients and Methods: This was a descriptive and analytical observational study conducted at CHUD-B/A from January 1, 2015, to August 31, 2019. It included pregnant women with sickle cell disease who gave birth to a liveborn neonate at the term of at least 28 weeks of amenorrhea. Variables studied were sociodemographic, clinical, and evolutionary. Analysis of the factors associated with early death was also carried out with a significance threshold set at p Results: Out of a total of 119 pregnant women, 95 neonates were recorded. Main morbidities were: prematurity and intrauterine growth restriction (49.5%);respiratory distress (40%), bacterial infection (30.5%), and perinatal asphyxia (21.1%). Early mortality rate was 8.4%. In bivariate analysis, the factors associated with early death were: parity (p < 0.001), the severity of maternal anemia (p < 0.008), birth weight under 1500 g (p < 0.002), the birth term under 32 weeks of amenorrhea (p < 0.001), resuscitation for at least 5 minutes (p = 0.001). In multivariate analysis, resuscitation for at least 5 minutes (p = 0.007) was mainly associated with early death. Conclusion: One out of two neonates of mothers with sickle cell disease has a low birth weight. Early mortality is high due to perinatal asphyxia. Hence the multidisciplinary care of these mothers.

Effect of a Nutrition Education Intervention on Mothers’ Infant and Young Child Feeding Knowledge and Practices in the Peri-Urban Areas of Bobo-Dioulasso: Before and after Study

Background: This study assessed the effect of a nutrition education intervention aiming to improve the knowledge and practices of under 5 years children’s mothers on infant and young child feeding in peri urban areas of Bobo-Dioulasso in Burkina Faso. Methods: A total of 243 mothers of children under 5 years in the peri-urban of Bobo-Dioulasso were surveyed before and after the intervention using the FAO questionnaire for infant and young child feeding (IYCF) knowledge and practices assessment in January and October 2017. The intervention included two components consisting of a theoretical phase (counselling and discussion) and cooking demonstrations implemented for ten months. To account for the before-and-after design of the study, the McNemar’s test was used to assess the effect of the intervention on mothers’ infant and young child feeding knowledge and practices. Results: The mean age of mothers was 29 ± 6.2 years and 50.6% of the mothers were between 20 and 29 years old. All indicators used to assess the mothers’ knowledge of breastfeeding and complementary feeding significantly improved after the intervention (all p-values < 0.05). In terms of child feeding practices, half of the indicators (early breastfeeding initiation, age of complementary feeding initiation, and minimum meal frequency) significantly increased (all p = 0.001) while two indicators (minimum dietary diversity, and minimum acceptable diet) did not change (p = 0.06 and 0.67) after the intervention. Finally, continued breastfeeding, significantly declined after the intervention (73.3% vs 86.0% p = 0.001). Conclusion: The intervention improved the mothers’ knowledge on breastfeeding and complementary feeding and some child feeding practices. This study provided some evidence of an effective nutrition education intervention to increase maternal knowledge and practices.

Determinants of Breastfeeding Practices among Working Mothers in Solwezi District of Zambia

Background: As one of the strategies to reduce infant morbidity and mortality, the World Health Organization recommends early initiation of exclusive breastfeeding and timely introduction of complementary feeding with continued breastfeeding for up to two years or beyond. Although breastfeeding is a natural process, it is influenced by different socio-cultural factors, habits, standards, and behaviours. Rapid industrialization and changes in lifestyle have seen increasing numbers of women in the labour force, and associated poor Exclusive Breastfeeding practices among working mothers. The aim of this study was to identify the determinants of breastfeeding practices among working mothers in Solwezi District of Zambia. Methods: This was a cross-sectional comparative survey comparing determinants of breastfeeding practices among working mothers aged 15 - 49 years in urban and rural areas of Solwezi District. The study was carried out in the Under-five Clinics at Solwezi, Kimasala and Mushitala Urban Clinics, as well as St. Francis, Kapijimpanga and Kisalala Rural Health Centers. Eighty-seven participants were successfully recruited using convenience sampling. A researcher-assisted questionnaire was used to collect data. Data analysis was done using SPSS version 27.0. Descriptive statistical analysis was done using numerical measures such as measures of central tendency and dispersion. The Pearson Chi Square test, correlation and linear regression analysis were performed to test association between the variables at the 0.05 level of significance. Are you assessing exclusive breastfeeding alone or what? Results: The mean age of respondents was 27.44 years (SD = 6.042 years) and the majority of the respondents were married (71.3%, n = 62). Forty-three percent of the respondents were self-employed while the rest were in formal government or private sector employment. Overall, 97.7% of the respondents had heard of exclusive breastfeeding, with health facilities being the most frequent source of information (64.4%). Attitude towards exclusive breastfeeding was generally positive. Fifty-eight percent of respondents exclusively breastfed while the rest were on mixed feeding. Seventy-one percent of respondents reported that their workplaces did not have breastfeeding facilities at work. Only 11.5% of the respondents reported having cultural beliefs restricting breastfeeding. Statistically significant associations were obtained from cross-tabulation analysis between respondent’s occupation and baby feeding type (p 0.001);workload and feeding type (0.024);as well as knowledge of EBF and feeding type (p 0.001). Conclusion: Majority of the respondents demonstrated good knowledge and positive attitude towards exclusive breastfeeding. This study recommends sensitization campaigns in communities to raise awareness about the importance of breastfeeding, and foster behaviour change that promotes breastfeeding.

Exploring the Lives of Mothers Raising Children with Autism Spectrum Disorder in Japan

Background: Examining the lives that mothers experience and build will allow us to deepen our understanding of children with ASD and their mothers and facilitate developing support methods. The study aimed to examine the lives of mothers raising children with autism spectrum disorder (ASD) and investigate their sources of support. Method: We conducted a qualitative inductive study using semi-structured interviews to identify characteristics of the lives that mothers have created. Results: Semi-structured interviews were conducted with 11 mothers having children with ASD. The analysis comprised three stages of coding and yielded eight categories. The lives of these mothers contained three themes: preoccupation with parenting children with ASD and their siblings;evolving mother;and using social resources. Mothers engaged in “assessing the characteristics, growth, and changes in the child with ASD”, had a “preoccupation with parenting children with ASD”, and were “thinking about the future of the child with ASD”, and “having goals and plans for parenting” while having “consideration toward the child’s siblings”. During this process, mothers experienced “changes in perspective or approach” and created lifestyles while “receiving help from people around them” and engaged in the “use of social resources”. Conclusions: To avoid becoming preoccupied with parenting and being burdened by their lifestyle, mothers require social support to monitor their perceptions. Furthermore, the utilization of social resources requires the supporting individuals to understand the characteristics of children with ASD, provide appropriate information, and assist in decision-making.

A Cooperative Security Monitoring Mechanism Aided by Optimal Multiple Slave Cluster Heads for UASNs

As each cluster head(CH)sensor node is used to aggregate,fuse,and forward data from different sensor nodes in an underwater acoustic sensor network(UASN),guaranteeing the data security in a CH is very critical.In this paper,a cooperative security monitoring mechanism aided by multiple slave cluster heads(SCHs)is proposed to keep track of the data security of a CH.By designing a low complexity“equilateral triangle algorithm(ETA)”,the optimal SCHs(named as ETA-based multiple SCHs)are selected from the candidate SCHs so as to improve the dispersion and coverage of SCHs and achieve largescale data security monitoring.In addition,by analyzing the entire monitoring process,the close form expression of the probability of the failure attack identification for the SCHs with respect to the probability of attack launched by ordinary nodes is deduced.The simulation results show that the proposed optimal ETA-based multiple SCH cooperation scheme has lower probability of the failure attack identification than that of the existing schemes.In addition,the numerical simulation results are consistent with the theoretical analysis results,thus verifying the effectiveness of the proposed scheme.

From“Mother Goddess”to“Mother”:A Comparison of the Image of Motherhood in“Lotus Lantern”and“Nezha:Birth of the Demon Child”*

The mother figure is the most frequent female figure in animated films.The portrayal of the mother figure in Lotus Lantern and Nezha:Birth of the Demon Child reflects the social construction of the mother figure in both films,and sheds light on the concepts and attitudes of women in society at different times.The mother figure in Lotus Lantern has the characteristics of a traditional ideal mother in a typically patriarchal culture;the mother figure in Nezha:Birth of the Demon Child returns to the realistic mother.The construction of the ideal mother to the realistic mother will also lead us to a more realistic understanding and concern for mothers and women in a realistic context.

Deoxyribonucleic Acid-Polymerase Chain Reaction Status of HIV Exposed Infants in a Sub Regional Prevention of Mother-to-Child Transmission of HIV Programme during the Period 2009-2020

Introduction: Transitioning to more efficacious Antiretrovirals for HIV infected pregnant women and infant prophylaxis has reduced Mother to child transmission of HIV significantly. This study aimed to determine HIV infection status in HIVexposed infants who had their first DNA polymerase chain reaction test in our molecular Laboratory. Subjects, Materials and Methods: Dried Blood Spots for HIV DNA results from 5 states between 2009 and 2020 were analyzed in the PCR laboratory of the Federal Teaching Hospital, Gombe. Results: Nine thousand eight hundred and twenty-three Human Immunodeficiency Virus Deoxyribonucleic acid polymerase Chain Reaction results were analysed;4937 (50.2%) were males. During the study period, there was an overall declining trend in the mother-to-child transmission rate from 3.8% in 2009 to 1.0% in 2020. 6120 (62.3%) of HIV + mothers received Highly active antiretroviral therapy HAART before pregnancy. 7845 (76.2%) of the infants received Nevirapine prophylaxis. Dried blood spot samples were collected from 4077 (41.5%) at 6 - 8 weeks. 8438 (85.9%) received cotrimoxazole. 9469 (96.4%) were ever breastfed. Of the 9823 HIV DNA PCR results, 255 (2.6%) were positive while 69/4077 (1.7%) and 109/2662 (4.1%) were positive for HIV DNA at 6 - 8 weeks and > 12 weeks respectively. (p = 0.001). 86/747 (11.5%) of infants whose HIV-positive mothers received no ARVS were HIV DNA positive. (p = 0.001). 106/884 (12.0%) of infants who had no Antiretroviral prophylaxis had positive HIV DNA results;7/413 (1.7%) with Zidovudine/Nevirapine prophylaxis had positive results. (p = 0.001). 246/9469 (2.6%) of infants that were ever breastfed were positive for HIV DNA;11/354 (3.0%) that never breastfed had positive HIV DNA. Conclusion: Lack of maternal/infant ARVs and prolonged breastfeeding increased the risk of infant HIV infection.
