RESUMO

Background and purpose: Although the transition process to motherhood of mothers who gave birth preterm has been examined using other theories, no studies have yet utilized Meleis's Transition Theory (TT). The aim of this study was to examine the transition process of mothers who gave birth preterm according to Meleis's TT. Methods: This study is a holistic single-pattern qualitative case study. The qualitative research paradigm was used based on the 32-item Qualitative Research Reporting Consolidated Criteria checklist, a guide for qualitative studies. Face-to-face interviews were conducted with 10 preterm mothers using a semistructured interview form between February 2019 and December 2021. The thematic analysis analysis method was used for the data obtained. After the data were transcribed, all the documents were read, and the data were deciphered. Using the notes, the codings were themed as titles and subtitles according to Meleis' TT. Results: Three main themes were determined using Meleis' TT: facilitators and inhibitors of the transition process, response patterns to motherhood, and nursing care. Visiting the baby in the intensive care unit, touching, and expressing milk for the baby were found to be important milestones in the mothers' transition process. Conclusion: Mothers faced numerous problems after premature birth and required support to cope with the transition process. They attempted to adapt to the transition to motherhood with the support of nurses, husbands, and families. Implications for practice: The researchers stated that may assist a healthy transition process by supporting health professionals to understand the problems faced by mothers during the transition to motherhood and to provide nursing care according to mothers' needs.

RESUMO

PROBLEM: Behaviours, such as smoking, alcohol use, unhealthy diet, lack of physical activity and vaccination non-adherence may lead to adverse pregnancy outcomes. BACKGROUND: Pregnancy has been identified as an opportune time for midwives to support women to make health behaviour changes. AIM: To synthesise existing qualitative research exploring midwives' experiences of discussing health behaviour change with women within routine care. METHODS: A systematic search was conducted across: Maternity and Infant Care, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, and Applied Social Sciences Index and Abstracts. Thematic analysis was used to synthesise the data. A professional and public advisory group provided feedback during the synthesis stage. FINDINGS: Twenty-two studies, published between 2005 and 2023, which represented findings from eight countries, were included in the review. The meta-synthesis revealed three themes: The midwife-woman relationship; Reflective and tailored behaviour change communication; Practical barriers to behaviour change conversations. This led to one overarching theme: Although midwives recognised the importance of behaviour change discussions, these conversations were not prioritised in clinical practice. CONCLUSION: Health behaviour change discussions were de-prioritised in midwives' clinical practice. Future research should explore intervention development to support midwives with their health behaviour change communication.

RESUMO

PROBLEM: COVID-19 impacted negatively on maternity care experiences of women and staff. Understanding the emergency response is key to inform future plans. BACKGROUND: Before the COVID-19 pandemic, experts highlighted concerns about UK community postnatal care, and its impact on long-term health, wellbeing, and inequalities. These appear to have been exacerbated by the pandemic. AIM: To explore community postnatal care provision during and since the pandemic across a large diverse UK region. METHODS: A descriptive qualitative approach. Virtual semi-structured interviews conducted November 2022-February 2023. All regional midwifery community postnatal care leaders were invited to participate. FINDINGS: 11/13 midwifery leaders participated. Three main themes were identified: Changes to postnatal care (strategic response, care on the ground); Impact of postnatal care changes (staff and women's experiences); and Drivers of postnatal care changes (COVID-19, workforce issues). DISCUSSION: Changes to postnatal care during the pandemic included introduction of virtual care, increased role of Maternity Support Workers, and moving away from home visits to clinic appointments. This has largely continued without evaluation. The number of care episodes provided for low and high-risk families appears to have changed little. Those requiring additional support but not deemed highest risk appear to have been most impacted. Staffing levels influenced amount and type of care provided. There was little inter-organisation collaboration in the postnatal pandemic response. CONCLUSION: Changes to postnatal care provision introduced more efficient working practices. However, evaluation is needed to ensure ongoing safe, equitable and individualised care provision post pandemic within limited resources.

RESUMO

BACKGROUND: Postpartum perineal pain is a frequent symptom (90%) with consequences on postnatal health regardless of whether the perineum remains intact. The impact of that pain on both short and long-term health has been studied and literature suggests midwives have a role to play in addressing this issue. However, the determinants of perineal pain when no lesions are identified are under researched and there is little understanding of women's views on this topic. AIM AND OBJECTIVES: The aim of the study was to gain an understanding of postpartum perineal pain when the perineum is considered to be intact. The objectives were •To gain an understanding of postpartum pain and its consequences on health and well-being •To explore women's views and understanding of perineal pain postpartum •To gain an understanding of the determinants of postpartum perineal pain when no anatomic lesion is diagnosed. METHODS: A Gadamerian hermeneutic approach was used to achieve a shared understanding of the issue. Participants were recruited from two maternity hospitals in the French area of Vaucluse. All women aged 18 to 45 years old, having given birth vaginally to a single live child and diagnosed with an intact perineum, were invited to participate in face-to-face interviews. Eleven participants were interviewed once, six of whom agreed to a second interview which took place over the telephone due to Covid lockdown. FINDINGS: The findings identified three major themes 1. Can't honestly call it pain, 2. Reassurance in normality, 3. Managing the unexpected. The use of the word pain to describe perineal sensations in postpartum was questioned by the participants, who used inner resources to deal with these sensations. Fostering self-confidence, having the possibility to explain the sensations and qualifying them as normal were some approaches women usedto manage their postpartum perineal sensations in a positive manner.

RESUMO

BACKGROUND:  Community-based postnatal care is a valuable resource in the provision of maternal and neonatal care, specifically outside the hospital environment. However, its application in maternal and neonatal care is not clearly documented in relation to the rendering of services by primary caregivers. OBJECTIVES:  This study clarifies the concept of 'community-based postnatal care' by using the concept analysis method. METHOD:  To analyse the concept, relevant literatures were reviewed and analysed using the Walker and Avant method, namely, selecting a concept, determining the purpose of analysis, identifying all uses of the concept, defining attributes, identifying a model case, identifying borderline, related and contrary cases, identifying antecedents and consequences and identifying the empirical referents. Characteristics that repeatedly appeared throughout the literature were noted and categorised. RESULTS:  It was established from the concept analysis that 'community-based postnatal care' was complex and experienced ethnically. The analysis included that primary caregiver participation was based on home-levelled-skilled care, community participation and mobilisation, linkages of health services and community stakeholders. The attributes were influenced by antecedents and consequences. CONCLUSION:  The empirical referents of community based can be integrated within the midwifery guidelines to measure the concept. When concepts are understood, self-care on early detection, early management and referral during early postnatal care will be enhanced.Contribution: The results of this study will foster independence, confidence and a respectful relationship between primary caregivers and the health care facility staff. The results are expected to guide future research and enhance community-based postnatal care in midwifery practice.

RESUMO

Care in the postnatal period is a goal for all families with a newborn baby, and support from nurses might prevent long-term health problems and contribute to a positive postnatal experience. This meta-ethnography aims to integrate and synthesize qualitative studies that illuminate and describe nurses' perspectives on municipal postnatal health care in high-income countries. Systematic literature searches for qualitative studies were conducted and 13 articles were included. The analysis followed the seven phases of Noblit and Hare. Being a "warrior" to care for the new family was identified as an overarching metaphor accompanied by three main themes: Stretching human boundaries, Stretching system boundaries, and Stretching knowledge boundaries. The overarching metaphor offers a deeper understanding of the nurses as "warriors" who despite tight timeframes and heavy workloads are stretching toward a caring relationship with the families. Being a warrior continuously pushing system boundaries puts the nurses in risk of being overstretched, balancing between their ideals and the reality. As more knowledge and clearer policies and procedures regarding the inclusion of fathers and LGBTQ parents in municipal postnatal healthcare are needed, more focus placed on the father or non-birthing parent, different cultural traditions and family constellations in practice and education is suggested.

RESUMO

BACKGROUND & AIMS: A balanced supply of arachidonic acid (ARA) and docosahexaenoic acid (DHA) may be crucial for quality of growth in preterm infants. This secondary analysis of a randomized controlled trial aimed to determine the effect of enhanced ARA and DHA supplementation on growth and body composition in infants born before 29 weeks of gestation. Furthermore, we aimed to study associations between human milk feeding, growth patterns and body composition. METHODS: The ImNuT-trial randomized 121 infants to receive a daily supplement with medium chain triglycerides (control) or 100 mg/kg ARA and 50 mg/kg DHA (ARA:DHA group) from the second day of life until 36 weeks postmenstrual age. Growth and body composition were evaluated up to 3 months corrected age. RESULTS: The ARA:DHA group showed better linear growth from birth to term equivalent age compared to the control group; mean difference in z score change from birth for length was 0.74 ([95% CI, 0.17-1.3]; p = 0.010). There were no differences in growth and body composition outcomes at 3 months corrected age between the groups. An increase in z score for weight after 36 weeks postmenstrual age and breastfeeding at 3 months corrected age were the strongest positive predictors of fat mass% at 3 months corrected age (both, p < 0.001). CONCLUSION: Early enhanced supplementation of ARA and DHA may be beneficial with respect to somatic growth in very preterm infants. CLINICAL TRIAL REGISTRATION: The trial has been registered on www. CLINICALTRIALS: gov, ID: NCT03555019.

RESUMO

We investigated the postpartum mental health of women who had consumed perilla oil or fish oil containing various omega-3 fatty acids for 12 weeks starting in mid-pregnancy. The association between fatty acids in maternal erythrocytes and mental health risk factors was also examined. Healthy Japanese primiparas in mid-pregnancy (gestational weeks 18-25) were randomly divided into two groups and consumed approximately 2.0 g/day of omega-3 fatty acids in either perilla oil (the ALA dose was 2.4 g/day) or fish oil (the EPA + DHA dose was 1.7 g/day) for 12 weeks. Maternal mental health was assessed using the Edinburgh Postnatal Depression Scale (EPDS) as the primary measure and the Mother-to-Infant Bonding Scale (MIBS) as the secondary measure. Data from an observational study were used as a historical control. Maternal blood, cord blood, and colostrum samples were collected for fatty acid composition analysis. In addition, completers of the observational studies were enrolled in a case-control study, wherein logistic regression analysis was performed to examine the association between maternal fatty acids and EPDS score. The proportion of participants with a high EPDS score (≥9) was significantly lower in the perilla oil group (12.0%, p = 0.044) but not in the fish oil group (22.3%, p = 0.882) compared with the historical control (21.6%), while the proportions between the former groups also tended to be lower (p = 0.059). No marked effect of omega-3 fatty acid intake was observed from the MIBS results. In the case-control study of the historical control, high levels of α-linolenic acid in maternal erythrocytes were associated with an EPDS score of <9 (odds ratio of 0.23, 95% confidence interval: 0.06, 0.84, p = 0.018 for trend). The results of this study suggest that consumption of α-linolenic acid during pregnancy may stabilize postpartum mental health.

RESUMO

During the critical period of postnatal development, brain maturation is extremely sensitive to external stimuli. Newborn rodents already have functional somatosensory pathways and the thalamus, but the cortex is still forming. Immature thalamic synapses may produce large postsynaptic potentials in immature neurons, while non-synaptic membrane currents remain relatively weak and slow. The thalamocortical system generates spontaneous and evoked early gamma and spindle-burst oscillations in newborn rodents. How relatively strong synapses and weak intrinsic currents interact with each other and how they contribute to early thalamic activities remains largely unknown. Here, we performed local field potential (LFP), juxtacellular, and patch-clamp recordings in the somatosensory thalamus of urethane-anesthetized rat pups at postnatal days 6-7 with one whisker stimulation. We removed the overlying cortex and hippocampus to reach the thalamus with electrodes. Deflection of only one (the principal) whisker induced spikes in a particular thalamic cell. Whisker deflection evoked a group of large-amplitude excitatory events, likely originating from lemniscal synapses and multiple inhibitory postsynaptic events in thalamocortical cells. Large-amplitude excitatory events produced a group of spike bursts and could evoke a depolarization block. Juxtacellular recordings confirmed the partial inactivation of spikes. Inhibitory events prevented inactivation of action potentials and gamma-modulated neuronal firing. We conclude that the interplay of strong excitatory and inhibitory synapses and relatively weak intrinsic currents produces sensory-evoked early gamma oscillations in thalamocortical cells. We also propose that sensory-evoked large-amplitude excitatory events contribute to evoked spindle-bursts.

RESUMO

BACKGROUND: The COVID-19 pandemic disrupted maternal and newborn health services in Bangladesh, exacerbating the large gaps in service utilization that existed prior to the pandemic. As part of its response, Bangladesh initiated remote antenatal and postnatal care telemedicine services led by midwives in 36 sub-district hospitals across five of Bangladesh's 64 districts. Gender-based violence screening and referral were integrated into the service to address a reported rise in violence following the country's pandemic lockdown. METHODS: Mixed-methods implementation research was used to develop an intrinsic case study describing the design and implementation of the telemedicine program. Qualitative analysis comprised document review, key informant interviews, and focus group discussions. Quantitative analysis employed an interrupted time series analysis with segmented multi-variate regression to compare maternity care service use trends before and after implementation. Poisson regression analysis was used to examine the trend in number of gender-based violence remote screenings, sessions held, and cases identified. RESULTS: A statistically significant change in trend for onsite antenatal and postpartum care as well as women seeking care at the hospital as a result of postpartum hemorrhage arising in the community was observed following the introduction of telemedicine. Facility births and cases of eclampsia appropriately identified and managed also had significant increases. In addition, over 6917 women were screened for GBV, 223 received counseling and 34 referrals were made, showing a statistically significant increase in frequency over time following the implementation of the telemedicine program. Challenges included that not all midwives adopted GBV screening, some women were reluctant to discuss GBV, there was an unanticipated need to introduce a patient visit scheduling system in all intervention hospitals, and many women were not reachable by phone due to lack of access or network coverage. CONCLUSIONS: Maternal health and gender-based violence telemedicine led by midwives was an effective, low-cost intervention in Bangladesh for addressing pandemic and pre-pandemic gaps in service use. Other low and middle-income countries planning to implement remote maternal health interventions via midwives should consider whether a patient visit scheduling system needs to be introduced, as well as limitations around mobile phone access and connectivity. Future research should include care quality oversight and improvement, and a more well-informed strategy for facilitating effective GBV screening.


To support the continuation of sexual and reproductive health services following pandemic lockdowns, Bangladesh introduced a midwife-led telemedicine program. Through the program, midwives who were already employed within the health system delivered remote antenatal and postnatal care, including gender-based violence screening and referral. The program operated in 36 sub-district hospitals across five of Bangladesh's 64 districts. Intrinsic implementation research was used to develop a case study describing the design and implementation of the telemedicine program. Qualitative and quantitative methods comprised document review, key informant interviews, focus group discussions, and service use trends. Analysis of the data identified a statistically significant trend increase for most maternity care services. Although they did increase significantly over time, referrals for GBV were less than expected, which may have been related to some midwives not screening for GBV, and/or that many women were reluctant to discuss GBV. In addition, there was an unanticipated need to introduce a patient visit scheduling system in all intervention hospitals, and many women were not reachable by phone due to lack of access or network coverage. In spite of this, 6197 women were screened for GBV. Of those, 223 received counseling and 34 received referrals. Overall, telemedicine led by midwives was an effective, low-cost intervention for maternal health, and a step toward stronger GBV response in Bangladesh. Other low and middle-income countries planning to implement remote maternal health interventions via midwives should consider what is needed to facilitate comfort for both providers and women as related to GBV screening, as well as practical issues regarding introducing scheduling systems and limitations of mobile phone access and connectivity.

RESUMO

BACKGROUND: Medicalised Conception (MAC) assists many couples to achieve pregnancy worldwide. As the impact of MAC has been linked to increased pregnancy-specific anxiety and parenting difficulties, this review aimed to explore parental experiences of pregnancy and early parenting following MAC, identifying parents' psychological, social and health needs. METHOD: Five databases were searched systematically from inception to March 2023. Identified articles were screened for eligibility against the inclusion criteria and the results were analysed using thematic synthesis. The Critical Appraisal Skills checklist was employed to appraise methodological quality. RESULTS: Twenty qualitative studies, drawing on a total of 19 participant samples, were included in this review, most with samples with history of subfertility. The findings were synthesised into three main themes (consisting of seven subthemes): 1) The vulnerable parent: fear, doubt, uncertainty, 2) the stark realisation of the parental dream, 3) psychosocial needs and support. Parents lacked a sense of safety during pregnancy and reported acting protectively both antenatally and postnatally. Furthermore, their identity transition was complex and non-linear, influenced by sociocultural context. CONCLUSIONS: Considerable unmet psychosocial needs were identified including the potential for anxiety in pregnancy, the possibility of feeling excluded and marginalised, and a reluctance to share distress and experiences with healthcare professionals. These findings suggest a need for consistent, holistic care, integrating psychological services.

RESUMO

OBJECTIVE: This study sought to investigate the level and determinants of receiving quality antenatal care (ANC), intrapartum care, and postnatal care (PNC) services by women in Ethiopia. The quality of care a woman receives during ANC, intrapartum care, and PNC services affects the health of the woman and her child and her likelihood of seeking care in the future. METHODS: Data from the nationally representative Ethiopia Mini Demographic and Health Survey 2019 were analysed for 5,527 mothers who gave birth within five years preceding the survey. We defined quality ANC as having: blood pressure measurement, urine and blood tests, informed of danger signs, iron supplementation, and nutritional counselling during ANC services; quality intrapartum care as having: a health facility birth, skilled birth assistance, and a newborn put to the breast within one hour of birth during intrapartum care services; and quality PNC as having: PNC within two days; cord examination; temperature measurement, and counselling on danger signs and breastfeeding of the newborn; and healthcare provider's observation of breastfeeding during PNC services. We used multilevel mixed-effects logistic regression analyses specifying three-level models: a woman/household, a cluster, and an administrative region to determine predictors of each care quality. The analyses employed sampling weights and were adjusted for sampling design. RESULTS: Thirty-six percent (n = 1,048), 43% (n = 1,485), and 21% (n = 374) women received quality ANC, intrapartum care and PNC services, respectively. Private healthcare facilities provided higher-quality ANC and PNC but poor-quality intrapartum care, compared to public health facilities. Having four or more ANC visits, commencing ANC during the first trimester, and higher women's education levels and household wealth indices were positive predictors of quality ANC use. Government health posts were less likely to provide quality ANC. Wealthier, urban-residing women with education and four or more ANC contacts were more likely to receive quality intrapartum care. Women who received quality ANC and skilled birth assistance were more likely to receive quality PNC. Teenage mothers were more likely to receive quality intrapartum care, but were less likely to receive quality PNC than mothers aged 20-49. CONCLUSIONS: We recommend standardizing the contents of ANC provided in all healthcare facilities; and promoting early and four or more ANC contacts, effectiveness, sensitivity and vigilance of care provided to teenage mothers, and women's education and economic empowerment.

RESUMO

Postpartum anemia is a very common maternal health problem and remains a persistent public health issue globally. It negatively affects maternal mood and could lead to depression, increased fatigue, and decreased cognitive abilities. It can and should be treated by restoring iron stores. However, in most health systems, there is typically a six-week gap between birth and the follow-up postpartum visit. Risks of postpartum maternal complications are usually assessed shortly after birth by clinicians intuitively, taking into account psychosocial and physical factors, such as the presence of anemia and the type of iron supplementation. In this paper, we investigate the possibility of using machine-learning algorithms to more reliably forecast three parameters related to patient wellbeing, namely depression (measured by Edinburgh Postnatal Depression Scale-EPDS), overall tiredness, and physical tiredness (both measured by Multidimensional Fatigue Inventory-MFI). Data from 261 patients were used to train the forecasting models for each of the three parameters, and they outperformed the baseline models that always predicted the mean values of the training data. The mean average error of the elastic net regression model for predicting the EPDS score (with values ranging from 0 to 19) was 2.3 and outperformed the baseline, which already hints at the clinical usefulness of using such a model. We further investigated what features are the most important for this prediction, where the EDPS score and both tiredness indexes at birth turned out to be by far the most prominent prediction features. Our study indicates that the machine-learning model approach has the potential for use in clinical practice to predict the onset of depression and severe fatigue in anemic patients postpartum and potentially improve the detection and management of postpartum depression and fatigue.

RESUMO

BACKGROUND: Early iron deficiency (ID) is a common risk factor for poorer neurodevelopment, limiting children's potential and contributing to global burden. However, it is unclear how early ID alters the substrate of brain functions supporting high-order cognitive abilities and whether the timing of early ID matters in terms of long-term brain development. This study aimed to examine the effects of ID during fetal or early postnatal periods on brain activities supporting proactive and reactive cognitive control in pre-adolescent children. METHODS: Participants were part of a longitudinal cohort enrolled at birth in southeastern China between December 2008 and November 2011. Between July 2019 and October 2021, 115 children aged 8-11 years were invited to participate in this neuroimaging study. Final analyses included 71 children: 20 with fetal ID, 24 with ID at 9 months (postnatal ID), and 27 iron-sufficient at birth and 9 months. Participants performed a computer-based behavioral task in a Magnetic Resonance Imaging scanner to measure proactive and reactive cognitive control. Outcome measures included accuracy, reaction times, and brain activity. Linear mixed modeling and the 3dlme command in Analysis of Functional NeuroImages (AFNI) were separately used to analyze behavioral performance and neuroimaging data. RESULTS: Faster responses in proactive vs. reactive conditions indicated that all groups could use proactive or reactive cognitive control according to contextual demands. However, the fetal ID group was lower in general accuracy than the other 2 groups. Per the demands of cues and targets, the iron-sufficient group showed greater activation of wide brain regions in proactive vs. reactive conditions. In contrast, such condition differences were reversed in the postnatal ID group. Condition differences in brain activation, shown in postnatal ID and iron-sufficient groups, were not found in the fetal ID group. This group specifically showed greater activation of brain regions in the reward pathway in proactive vs. reactive conditions. CONCLUSIONS: Early ID was associated with altered brain functions supporting proactive and reactive cognitive control in childhood. Alterations differed between fetal and postnatal ID groups. The findings imply that iron supplement alone is insufficient to prevent persisting brain alterations associated with early ID. Intervention strategies in addition to the iron supplement should consider ID timing.

RESUMO

Background: Anemia is highly prevalent globally and disproportionately affects postnatal women. It is a significant cause of maternal mortality and morbidity globally. Objective: The main aim of this study was to determine the extent of postpartum anemia and associated factors among postnatal women in two selected health facilities in Gondar, Northwest Ethiopia. Methods: A facility-based, cross-sectional study was conducted among 282 postnatal women from March to May 2021. A systematic sampling technique was used to recruit study participants from each institute. Sociodemographic, obstetric, and clinical data were collected through a semi-structured questionnaire. A venous blood sample was collected to determine the red blood cell parameters. A thin blood smear preparation was performed to examine blood morphology. In addition, direct wet mount and formalin-ether sedimentation techniques were used for stool examination to identify intestinal parasites. Data were entered into EpiData and exported to Stata 14 for statistical analysis. Descriptive statistics were presented in text, tables, and figures. A binary logistic regression model was used to identify factors associated with postpartum anemia. A p-value <0.05 was considered statistically significant. Results: The proportion of postpartum anemia was 47.16%; 95% CI; 41.30-53.03 with moderate, mild, and severe anemia accounting for 45.11, 42.86, and 12.03%, respectively. The majority of the anemia (94%) was of the normocytic normochromic type. It was associated with postpartum hemorrhage (AOR = 2.23; 95% CI: 1.24-4.01), cesarean section (AOR = 4.10; 95% CI: 2.11-7.78), lack of iron and folate supplementation during pregnancy (AOR = 2.12; 95% CI: 1.17-4.02), and low diet diversity level (AOR = 1.83; 95% CI: 1.05-3.18). Conclusion: The prevalence of anemia was found to be a major public health concern. Iron and folate supplementation during pregnancy, improved management of PPH, an effective cesarean section with post-operative care, and taking a diversified diet will reduce the burden. Therefore, identified factors should be considered to prevent and control postpartum anemia.

RESUMO

Background: Maternal and child health (MCH) services have been affected by the Coronavirus disease (COVID-19) pandemic in all countries, including Indonesia. Information regarding the impact of COVID-19 on MCH service access and provision is limited, particularly in the context of rural Indonesian communities. This study aimed to explore the experiences of Indonesian mothers and midwives from a rural regency regarding MCH services delivery during the pandemic. Methods: This study was a sub-study of a pre-existing cohort study conducted in four sub-districts in Banggai, Indonesia, as the qualitative research. This study was conducted from November 2020 to April 2021, involving 21 mothers and six midwives. We selected the participants using snowball sampling. In-depth interviews were conducted in Bahasa. The study used both deductive and inductive approaches for analysis. Data analysis was performed using NVivo v.12. Results: The study identified three themes and eight sub-themes from the analysis incorporating the midwives' and mothers' data. The themes included health service change, perceived barriers to service delivery, and family impact. This study highlights health service changes due to the pandemic, such as relocating the MCH services. Mothers perceived barriers to accessing health services, including distance reasons and fear of COVID-19. Only the shortages of staff affected the midwives in providing optimal services. Conclusion: The pandemic triggered health service changes and caused some barriers to service delivery. This study recommends that the local government and stakeholders should pay more attention to the health service changes according to the mothers' experiences and address barriers to optimize access to MCH services during the pandemic.

RESUMO

Melatonin has been documented to alleviate compromised pregnancies and enhance livestock performance traits. The objective of this study was to determine the effect of prenatal and postnatal melatonin supplementation on overall calf performance and dam milking traits in relation to calves, molecular factors involved in growth and metabolism of calves, along with testicular physiology and fertility traits in subsequent bulls. On days 190, 220 and 250 of gestation, dams (N = 60) were administered either two subdermal ear melatonin implants (preMEL) or no implants (preCON). After parturition, birth weights were recorded and calves were blocked based on prenatal treatment and sex. Calves received either melatonin implants (posMEL) or none (posCON) on days 0, 30, and 60 of age. On day 60 of lactation, a subset of dams (N = 32) were selected based on age, weight, and calf sex for milk collection and analysis. At weaning, (day 210 postnatally) calf weight, morphometric data, liver samples, and loin samples were collected. At 12 mo of age, bull (N = 30) scrotal circumference, scrotal temperature, and testicular artery measurements were recorded. Milk yield and fat percent from dams tended to decrease in the preMEL group (P < 0.07) compared with preCON group. Prenatal melatonin administration did not affect (P = 0.95) calf birth weight and similarly calf weaning weight was unaffected (P < 0.10) by prenatal or postnatal melatonin supplementation. Blood analysis demonstrated that plasma concentrations of melatonin were not different (P = 0.12) in dams; however, an increase (P < 0.001) in plasma concentrations of melatonin was observed in posMEL vs. posCON calves. A tendency (P < 0.10) for decreased MYF5 and MYOD1 expression in loin muscle was observed in the posMEL calves. Prenatal and postnatal melatonin administration did not affect subsequent bull scrotal measurements or testicular hemodynamics (P ≥ 0.14). Administering supplemental melatonin via implants during the prenatal and postnatal phase did not alter performance characteristics in offspring. In this study, dams were implanted in winter months, whereas calves were implanted in the spring months. Seasonal differences involving photoperiod and ambient temperature might have attributed to a lack of differences in melatonin levels during the prenatal phase. In the postnatal period, the level of developmental plasticity appears to be too low for melatonin properties to be effective.


Previous studies have examined maternal melatonin implants in fall calving Mississippi cattle during the third trimester of pregnancy. These studies have shown increased maternal uterine blood flow without any change in calf birth weight when supplemented with melatonin implants. However, calf weaning weights were increased in calves born to melatonin supplemented dams vs. their control counterparts. The objective of this study was to examine offspring performance following maternal melatonin supplementation (prenatal) and/or postnatal calf melatonin supplementation in spring calving Montana cattle. Calf performance and weight at weaning were not affected by maternal or postnatal melatonin supplementation. However, dam milk yield and fat percent were decreased in the melatonin supplemented dams. Maternal and postnatal melatonin supplementation did not affect bull measurements of reproductive performance. Interestingly, maternal concentrations of melatonin were not different between dam treatment groups; however, postnatal melatonin supplementation increased calf concentrations of melatonin. In this study, dams were implanted in winter months, whereas calves were implanted in the spring months. Seasonal differences involving photoperiod and ambient temperature may attribute to a lack of differences in melatonin levels during the prenatal phase.

RESUMO

Our objectives were to evaluate the impact of supplementary trace mineral (TM) form-inorganic salts (STM; Co, Cu, Mn, Zn sulfates, and Na selenite) or organic (OTM; Co, Cu, Mn, Zn proteinates, and selenized yeast)-in the prepartum diet on quantity and quality of colostrum, passive immunity, antioxidant biomarkers, cytokine responses to lipopolysaccharide (LPS), health, and growth of newborn calves. Pregnant heifers (n = 100) and cows (n = 173) were enrolled at 45 d before calving, blocked by parity and body condition score, and allocated randomly to STM (50 heifers; 86 cows) or OTM (50 heifers; 87 cows) supplementation. Cows in both treatments were fed the same diet, except for the source of supplementary TM. Within 2 h of calving, dams and calves were separated, colostrum was harvested, the yield was measured, and a sample was saved for posterior analyses of colostrum quality. A subgroup of calves (n = 68) had a blood sample collected before colostrum feeding. After colostrum feeding, all samples and data collection were limited to 163 calves (STM = 82; OTM = 81) fed 3 L of good quality (Brix% >22) maternal colostrum via nipple bottle minutes after harvesting. Concentration of IgG in colostrum and serum was determined 24 h after colostrum feeding using radial immunodiffusion. Concentration of TM in colostrum and serum were performed by inductively coupled plasma mass spectrometry. Activity of glutathione peroxidase, ferric reducing ability of plasma, and concentration of superoxide dismutase were evaluated in plasma by colorimetric assays. Ex vivo whole blood stimulation with LPS was performed on d 7 of life to evaluate cytokine responses in a subgroup of 66 calves. Health events were recorded from birth to weaning, and body weight was recorded at birth (all calves) and on d 30 and 60 (heifers only). Continuous variables were analyzed by ANOVA and binary responses were analyzed by logistic regression. Complete replacement of STM by OTM in prepartum diet resulted in greater concentration of Se (461 vs. 543 ± 7 µg/g; ± SEM) but did not alter the concentration or total mass of other TM and IgG in colostrum. Female calves of the OTM group had greater concentration of Se in serum at birth (0.23 vs. 0.37 ± 0.05 µg/mL), were lighter in weight at birth (40.9 vs. 38.8 ± 0.6 kg) and weaning (93.2 vs. 89.7 ± 1.6 kg) than those of the STM group. Maternal treatments did not affect passive immunity or antioxidant biomarkers. On d 7, basal concentrations (log10 of concentration in pg/mL) of IFNγ (0.70 vs. 0.95 ± 0.083) and LPS-stimulated concentrations of CC chemokine ligand 2 (CCL2; 2.45 vs. 2.54 ± 0.026), CC chemokine ligand 3 (CCL3; 2.63 vs. 2.76 ± 0.038), IL-1α (2.32 vs. 2.49 ± 0.054), and IL-1ß (3.62 vs. 3.86 ± 0.067) were greater in OTM than in STM. Supplementation with OTM in pregnant heifers, but not in pregnant cows, reduced the incidence of preweaning health problems in their calves (36.4 vs. 11.5%). Complete replacement of STM by OTM in the prepartum diet did not cause major changes in colostrum quality, passive immunity, and antioxidant capacity, but increased cytokine and chemokine responses to LPS on d 7 of life and benefited preweaning health of calves born to primiparous cows.

RESUMO

Introduction: dietary intake and optimal gestational weight gain are important factors leading to a positive outcome for both mothers and their infants. Women who consume inadequate diet and gain inadequate weight during pregnancy are at risk of bearing a baby with low birth weight, whereas those who gain excessive weight are at increased risk of preeclampsia, having macrosomal babies, and gestational diabetes. The study aimed to assess the effect of maternal dietary intake, gestational weight on birth weight among pregnant women in Tamale Metropolis. Methods: the study was a health-facility-based analytical cross-sectional study that involved 316 postnatal mothers. A semi-structured questionnaire was used to collect the data. Data collected were analyzed using STATA version 12. Multiple logistic regression model was estimated to determine the predictors of birth weight. Statistical significance was set at p<0.05. Results: the study showed 17.8%, 55.9%, and 26.4% prevalence of inadequate, adequate, and excessive gestational weight gain, respectively. Although, all respondents consume supper every day, only 40.0% consumes snacks daily, 97.5% and 98.7% consumes breakfast and lunch daily respectively. Majority of the respondents (92.4%) had acceptable minimum dietary diversity. About 11.0% and 4.0% of the babies were low birth weight and macrosomic, respectively. Furthermore, the prevalence of inadequate and adequate dietary intake was, respectively, 7.6% and 92.4%. The results showed that underweight before pregnancy (BMI<18Kg/m2) (AOR=8.3, 95% CI: 6.7-15.0) and inadequate weight gain during pregnancy (AOR=4.5, 95% CI: 3.9-6.5) were significant determinant of low birthweight baby. Conclusion: on the whole, maternal body mass index and weight gain during pregnancy were strong predictors of low birth weight. Low birth weight is a major public health concern and the causes multifaceted in natures. Therefore, to deal with low birth weight, a more holistic and multi-sectoral approaches such as behaviour change communication and comprehensive preconception care are required.

RESUMO

The third ventricle (3 V) wall of the tuberal hypothalamus is composed of two types of cells; specialized ependymoglial cells called tanycytes located ventrally and ependymocytes dorsally, which control the exchanges between the cerebrospinal fluid and the hypothalamic parenchyma. By regulating the dialogue between the brain and the periphery, tanycytes are now recognized as central players in the control of major hypothalamic functions such as energy metabolism and reproduction. While our knowledge of the biology of adult tanycytes is progressing rapidly, our understanding of their development remains very incomplete. To gain insight into the postnatal maturation of the 3 V ependymal lining, we conducted a comprehensive immunofluorescent study of the mouse tuberal region at four postnatal ages (postnatal day (P) 0, P4, P10, and P20). We analyzed the expression profile of a panel of tanycyte and ependymocyte markers (vimentin, S100, connexin-43 [Cx43], and glial fibrillary acidic protein [GFAP]) and characterized cell proliferation in the 3 V wall using the thymidine analog bromodeoxyuridine. Our results show that most changes in marker expression occur between P4 and P10, with a switch from a 3 V mostly lined by radial cells to the emergence of a tanycytic domain ventrally and an ependymocytic domain dorsally, a drop in cell proliferation and increased expression of S100, Cx43, and GFAP that acquire a mature profile at P20. Our study thus identifies the transition between the first and the second postnatal week as a critical time window for the postnatal maturation of the 3 V wall ependymal lining.
