    INTRODUCTION: Exclusive breastfeeding is still below the set target. Breastfeeding behavior is influenced by knowledge and self-efficacy. Training packages based on family centered maternity care are needed to boost mothers' efficacy and knowledge about breastfeeding. The aim of this study is to evaluate the effect of an online education package based on Family Centered Maternity Care on the self efficacy and knowledge of breastfeeding mothers.

    MATERIALS AND METHODS: This Study used a pre-experimental design method with a One-Group Pre-Post test design approach. We recruited 60 breastfeeding mothers in Padang, Indonesia, selected with consecutive sampling. Online Education Based On Family Centered Maternity Care was provided for the respondent. Data were collected using the Breastfeeding Self efficacy Scale ShortForm (BSE-SF) and The Breastfeeding Knowledge (BKQ) Questionnaires.

    RESULTS: The respondents had significant differences in selfefficacy and knowledge before and after the health education Based On Family Centered Maternity Care (p<0.001).

    CONCLUSION: After Education Package Based On Family Centered Maternity Care influenced the Self Efficacy And Knowledge of Breastfeeding Mothers. It could be provided as a nursing intervention to assist Breastfeeding Mothers.

    INTRODUCTION: Most evidence about the management of cancer and hematological malignancy in pregnancy are derived from retrospective observational studies with a small sample size. Availability of sufficiently large data has enabled evidence-based decision-making in this clinical dilemma.

    MATERIALS AND METHODS: Retrospective study looking into patients diagnosed with acute leukemia or lymphoma in pregnancy from 1st January 2014 to 1st January 2020 in Ampang General Hospital including newly or previously diagnosed and relapsed disease RESULTS: 37 cases of acute leukemia or lymphoma in pregnancy occurred in 34 patients. Majority of acute leukemia or lymphoma in pregnancy diagnosed in 1st trimester or in the setting of previously established or relapsed disease was therapeutically terminated. Thirteen pregnancies treated with antenatal chemotherapy resulted in livebirths except one stillbirth. More adverse obstetric outcomes are observed in pregnancies that did not receive antenatal chemotherapy, but association did not reach statistical significance. There was no significant difference in fetal outcome between cohort with and without antenatal chemotherapy. No treatment related mortality was observed in pregnancies with antenatal chemotherapy. Overall survival for newly diagnosed acute leukemia in pregnancy is significantly better with antenatal chemotherapy versus no antenatal chemotherapy.

    CONCLUSION: Treatment with chemotherapy in 2nd trimester of pregnancy onwards appears to have tolerable risks with favorable obstetric and fetal outcome. Deferment of treatment for acute leukemia in pregnancy to after delivery may cause increased risk of maternal and fetal adverse outcome.

    Intrapericardial teratoma is a germ-cell tumor that typically arises from the base of the heart. This rare cardiac tumour is the second most common tumor diagnosed in fetuses and newborn. Although benign, it can be massive in size causing direct compression on the heart and associated with significant pericardial effusion resulting life-threatening complications such as cardiac tamponade, heart failure, foetal hydrops, and sudden death. Early antenatal diagnosis and surgical intervention improve the survival. We present a case of immature intrapericardial teratoma diagnosed at 25 weeks of gestation but required multiple foetal pericardiocentesis and premature delivery due to massive pericardial effusion. The importance of multidisciplinary team approach to ensure successful management was highlighted in this case report.

    BACKGROUND: Hyperemesis gravidarum (HG) affects about 2% of pregnancies and is at the severe end of the spectrum of nausea and vomiting of pregnancy. HG causes severe maternal distress and results in adverse pregnancy outcomes long after the condition may have dissipated. Although dietary advice is a common tool in management, trial evidence to base the advice on is lacking.

    METHODS: A randomized trial was conducted in a university hospital from May 2019 to December 2020. 128 women at their discharge following hospitalization for HG were randomized: 64 to watermelon and 64 to control arm. Women were randomized to consume watermelon and to heed the advice leaflet or to heed the dietary advice leaflet alone. A personal weighing scale and a weighing protocol were provided to all participants to take home. Primary outcomes were bodyweight change at the end of week 1 and week 2 compared to hospital discharge.

    RESULTS: Weight change (kg) at end of week 1, median[interquartile range] -0.05[-0.775 to + 0.50] vs. -0.5[-1.4 to + 0.1] P = 0.014 and to the end of week 2, + 0.25[-0.65 to + 0.975] vs. -0.5[-1.3 to + 0.2] P = 0.001 for watermelon and control arms respectively. After two weeks, HG symptoms assessed by PUQE-24 (Pregnancy-Unique Quantification of Emesis and Nausea over 24 h), appetite assessed by SNAQ (Simplified Nutritional Appetite Questionnaire), wellbeing and satisfaction with allocated intervention NRS (0-10 numerical rating scale) scores, and recommendation of allocated intervention to a friend rate were all significantly better in the watermelon arm. However, rehospitalization for HG and antiemetic usage were not significantly different.

    CONCLUSION: Adding watermelon to the diet after hospital discharge for HG improves bodyweight, HG symptoms, appetite, wellbeing and satisfaction.

    Bisphenol A (BPA) is a plasticiser used in the manufacturing of many products and its effects on human health remain controversial. Up till now, BPA involvement in metabolic syndrome risk and development is still not fully understood. In this study, we aimed to investigate the effect of prenatal BPA exposure with postnatal trans-fat diet intake on metabolic parameters and pancreatic tissue histology. Eighteen pregnant rats were divided into control (CTL), vehicle tween 80 (VHC), and BPA (5 mg/kg/day) from gestational day (GD) 2 until GD 21, then their weaning rat's offspring were fed with normal diet (ND) or trans-fat diet (TFD) from postnatal week (PNW) 3 until PNW 14. The rats were then sacrificed and the blood (biochemical analysis) and pancreatic tissues (histological analysis) were collected. Glucose, insulin, and lipid profile were measured. The study has shown that there was no significant difference between groups with regard to glucose, insulin, and lipid profiles (p > 0.05). All pancreatic tissues showed normal architecture with irregular islets of Langerhans in TFD intake groups compared to offspring that consumed ND. Furthermore, the pancreatic histomorphometry was also affected whereby the study findings revealed that there was a significant increase in the mean number of pancreatic islets in rats from BPA-TFD group (5.987 ± 0.3159 islets/field, p = 0.0022) compared to those fed with ND and BPA non-exposed. In addition, the results have found that prenatal BPA exposure resulted in a significant decrease in the pancreatic islets diameter of the BPA-ND group (183.3 ± 23.28 µm, p = 0.0022) compared to all other groups. In conclusion, prenatal BPA exposure with postnatal TFD in the offspring may affect glucose homeostasis and pancreatic islets in adulthood, and the effect may be more aggravated in late adulthood.

    Epigenetics refers to how gene expression and function are modulated without modifying the DNA sequence but through subtle molecular changes or interactions with it. As spermatogenesis progresses, male germ cells suffer plenty of epigenetic modifications, resulting in the definitive epigenome of spermatozoa conditioning its functionality, and this process can be altered by several internal and external factors. The paternal epigenome is crucial for sperm function, fertilization, embryo development, and offspring's health, and altered epigenetic states are associated with male infertility with or without altered semen parameters, embryo quality impairment, and worse ART outcomes together with the future offspring's health risks mainly through intergenerational transmission of epigenetic marks. Identifying epigenetic biomarkers may improve male factor diagnosis and the development of targeted therapies, not only to improve fertility but also to allow an early detection of risk and disease prevention in the progeny. While still there is much research to be done, hopefully in the near future, improvements in high-throughput technologies applied to epigenomes will permit our understanding of the underlying epigenetic mechanisms and the development of diagnostics and therapies leading to improved reproductive outcomes. In this review, we discuss the mechanisms of epigenetics in sperm and how epigenetics behave during spermatogenesis. Additionally, we elaborate on the relationship of sperm epigenetics with sperm parameters and male infertility, and highlight the impact of sperm epigenetic alterations on sperm parameters, embryo quality, ART outcomes, miscarriage rates and offspring's health. Furthermore, we provide insights into the future research of epigenetic alterations in male infertility.

    Continuous Spinal Anaesthesia (CSA) technique has all the advantages of single-shot spinal anaesthesia with the added benefit of prolonging the duration of anaesthesia. CSA has been used as a primary method of anaesthesia as an alternative to general anaesthesia in high-risk and elderly patients for various elective and emergency surgical procedures involving the abdomen, lower limbs, and vascular surgeries. CSA has also been used in some obstetrics units. Despite its advantages, CSA technique remains underutilised because it is surrounded with myths, mysteries, and controversies concerning neurological, other morbidities and minor technical difficulties. This article includes a description of CSA technique compared to other contemporary central neuraxial blocks. It also discusses the perioperative applications of CSA for different surgical and obstetrics procedures, advantages, disadvantages, complications, problems, and pointers on how to perform the technique safely.

    Hypertension is the leading risk factor for cardiovascular disease and premature death among women globally. However, there is a fundamental lack of knowledge regarding the sex-specific pathophysiology of the condition. In addition, risk factors for hypertension and cardiovascular disease unique to women or female sex are insufficiently acknowledged in clinical guidelines. This review summarizes the existing evidence on women and female-specific risk factors and clinical management of hypertension, to identify critical knowledge gaps relevant to research, clinical practice, and women's heart health awareness. Female-specific risk factors relate not only to reproduction, such as the association of gynecological conditions, adverse pregnancy outcomes or menopause with hypertension, but also to the specific roles of women in society and science, such as gender differences in received medical care and the underrepresentation of women in both the science workforce and as participants in research, which contribute to the limited evidence-based, gender- or sex-specific recommendations. A key point is that the development of hypertension starts in young, premenopausal women, often in association with disorders of reproductive organs, and therefore needs to be managed early in life to prevent future cardiovascular disease. Considering the lower blood pressure levels at which cardiovascular disease occurs, thresholds for diagnosis and treatment of hypertension may need to be lower for women.

    The body of evidence supports the negative impact of increased sperm DNA fragmentation (SDF) on natural fertility as well as assisted reproduction conditions. High SDF has been correlated with low pregnancy and delivery rates following intrauterine insemination. Also, high SDF is accused of reducing the rates of fertilization, implantation, pregnancy, and live birth following in-vitro fertilization (IVF). Despite no impact of high SDF on fertilization or pregnancy rates following intracytoplasmic sperm injection (ICSI), it has been correlated with poor embryo quality and a higher risk of miscarriage. Several methods have been introduced to help select sperm with the best DNA quality to be used in assisted reproductive technology procedures. These include magnetic-activated cell sorting, intracytoplasmic morphologically selected sperm injection, physiologic ICSI, and microfluidic sperm sorters, among others. This article aimed to discuss the impact of high SDF in infertile men on the reproductive outcome of couples undergoing IVF/ICSI. Additionally, this review highlights the principles, advantages, and limitations of different techniques that are currently used for the selection of sperm with intact DNA to be utilized for ICSI.

    Male infertility is attributed to multiple factors including high levels of sperm DNA fragmentation (SDF). Conventional semen analysis continues to be the gold standard for diagnosis of male factor infertility around the world. However, the limitations of basic semen analysis have prompted the search for complementary assessments of sperm function and integrity. Sperm DNA fragmentation assays (direct or indirect) are emerging as important diagnostic tools in male infertility workups, and have been advocated for use in infertile couples for a variety of reasons. While a controlled degree of DNA nicking is required for appropriate DNA compaction, excessive fragmentation of sperm DNA is linked to impaired male fertility potential, decreased fertilization, poor embryo quality, recurrent pregnancy loss, and failure of assisted reproductive technology procedures. However, there is an ongoing debate regarding whether or not to employ SDF as a routine test for male infertility. This review compiles up-to-date information regarding the pathophysiology of SDF, the currently available SDF tests, and the role of SDF tests in natural and assisted conception conditions.

    INTRODUCTION: Postpartum depression (PPD) is a chronic mood illness that typically develops in the first few months after giving birth. It affects 17.2% of women worldwide, and its deleterious consequences on infants, children, and mothers have elicited global public concern. Therefore, this paper aims to present an overview of the relationship between emotional support and PPD among postpartum mothers in the Asia region.

    METHODS: An extensive search using various keywords was conducted in Science Direct, PsycINFO, PubMed, Scopus, Cochrane Library, JSTOR, Springer Link, and Taylor Francis. The screening process was compliant with the PRISMA guideline, while the quality of the selected studies was assessed using the QuADS tool.

    RESULTS: The analysis included 15 research from 12 different countries with 6031 postpartum mothers. A decreased risk of PPD for postpartum mothers is shown to be significantly correlated with greater emotional support, and vice versa.

    DISCUSSION: Asian women are less likely to seek emotional assistance than other mothers, which is influenced by culture. There needs to be more research on the impact of culture on postpartum mothers' emotional support. Additionally, this review hopes to raise awareness among the mothers' friends and family as well as the medical community to be more attentive to postpartum mothers' emotional needs and offer specialized assistance.

    BACKGROUND: A majority of pregnant women experience sleep disruption during pregnancy, especially in the third trimester. Lack of sleep is associated with preterm birth, prolonged labor and higher cesarean section rate. Six or less hours of night sleep in the last month of pregnancy is associated with a higher rate of caesarean births. Eye-masks and earplugs compared to headband improve night sleep by 30 or more minutes. We sought to evaluate eye-mask and earplugs compared to sham/placebo headbands on spontaneous vaginal delivery.

    METHODS: This randomized trial was conducted from December 2019-June 2020. 234 nulliparas, 34-36 weeks' gestation with self-reported night sleep

    Maternal obesity can be considered an intergenerational cycle and is also an important indicator of cognitive impairments. It is thought that using natural products is the best and safest way to combat maternal obesity and associated complications. Recent studies have shown that Elateriospermum tapos (E. tapos) contains bioactive compounds with anti-obesity effects, and yoghurt is a convenient medium for supplementing obese maternal rats with E. tapos extract. Thus, the aim of this study is to investigate the impact of E. tapos in yoghurt on maternally obese rats' cognitive function supplemented with a high-fat diet (HFD). In this study, 48 female Sprague-Dawley rats were used. The rats were fed HFD for a period of 16 weeks to induce obesity, after which they were allowed to mate. Upon confirmation of pregnancy, obese rats were given varying doses of E. tapos (5, 50, and 500 mg/kg) in yoghurt until postnatal (PND) day 21. On PND 21, the dams' body mass index (BMI), Lee index, abdominal circumference, oxidative status, and metabolic profile were measured. The behavioral tests (open field, place, and object recognition) were conducted on PND 21 to access memory. The results show that the 50 and 500 mg/kg E. tapos in yoghurt supplemented groups had similar BMI, Lee index, abdominal circumference, lipid profile, FBG, insulin, FRAP, and GSH levels, as well as a similar recognition index, in comparison with the control group supplemented with saline. In conclusion, the results of this study indicate that the newly formulated E. tapos in yogurt can act as an anti-obesity agent in maternal obesity, alleviate anxiety, and enhance hippocampal-dependent memory.

    Gastroschisis has increased globally over recent decades, and this increase has not been explained by identified risk factors. We conducted a population-based study of infants born in Canada, 2004-2020. We used "winter" months (i.e., September through June) and northern areas of residence as indicators of less sunlight/less active lifestyle, while "summer" (i.e., July and August) and southern areas were considered as reference. Rate of gastroschisis for infants conceived in winter (3.4 per 10,000) was higher than for infants conceived in summer (2.2 per 10,000; p

    BACKGROUND: Are thermoregulation and golden hour practices in extremely preterm (EP) infants comparable across the world? This study aims to describe these practices for EP infants based on the neonatal intensive care unit's (NICUs) geographic region, country's income status and the lowest gestational age (GA) of infants resuscitated.

    METHODS: The Director of each NICU was requested to complete the e-questionnaire between February 2019 and August 2021.

    RESULTS: We received 848 responses, from all geographic regions and resource settings. Variations in most thermoregulation and golden hour practices were observed. Using a polyethylene plastic wrap, commencing humidity within 60 min of admission, and having local protocols were the most consistent practices (>75%). The odds for the following practices differed in NICUs resuscitating infants from 22 to 23 weeks GA compared to those resuscitating from 24 to 25 weeks: respiratory support during resuscitation and transport, use of polyethylene plastic wrap and servo-control mode, commencing ambient humidity >80% and presence of local protocols.

    CONCLUSION: Evidence-based practices on thermoregulation and golden hour stabilisation differed based on the unit's region, country's income status and the lowest GA of infants resuscitated. Future efforts should address reducing variation in practice and aligning practices with international guidelines.

    IMPACT: A wide variation in thermoregulation and golden hour practices exists depending on the income status, geographic region and lowest gestation age of infants resuscitated. Using a polyethylene plastic wrap, commencing humidity within 60 min of admission and having local protocols were the most consistent practices. This study provides a comprehensive description of thermoregulation and golden hour practices to allow a global comparison in the delivery of best evidence-based practice. The findings of this survey highlight a need for reducing variation in practice and aligning practices with international guidelines for a comparable health care delivery.

    While artificial intelligence (AI) offers promising solutions in healthcare, it also poses a number of threats to human health and well-being via social, political, economic and security-related determinants of health. We describe three such main ways misused narrow AI serves as a threat to human health: through increasing opportunities for control and manipulation of people; enhancing and dehumanising lethal weapon capacity and by rendering human labour increasingly obsolescent. We then examine self-improving 'artificial general intelligence' (AGI) and how this could pose an existential threat to humanity itself. Finally, we discuss the critical need for effective regulation, including the prohibition of certain types and applications of AI, and echo calls for a moratorium on the development of self-improving AGI. We ask the medical and public health community to engage in evidence-based advocacy for safe AI, rooted in the precautionary principle.

    Activin A is a two-subunit protein belonging to the transforming growth factor β superfamily. First discovered almost three decades ago, it has since been implicated in diverse physiological roles, ranging from wound repair to reproduction. After 30 years of research, altered activin A levels are now understood to be associated with the development of various diseases, making activin A a potential therapeutic target. In pregnancy, the placenta and fetal membranes are major producers of activin A, with significantly enhanced serum concentrations now recognised as a contributor to numerous gestational disorders. Evidence now suggests that circulating levels of activin A may be clinically relevant in the early detection of pregnancy complications, including miscarriage and preeclampsia. This review aims to summarise our current understanding of activin A as a potential diagnostic marker in common pregnancy pathologies.

    Rationale: Premature birth is an independent predictor of long-term cardiovascular risk. Individuals affected are reported to have a lower rate of [Formula: see text]o2 at peak exercise intensity ([Formula: see text]o2PEAK) and at the ventilatory anaerobic threshold ([Formula: see text]o2VAT), but little is known about their response to exercise training. Objectives: The primary objective was to determine whether the [Formula: see text]o2PEAK response to exercise training differed between preterm-born and term-born individuals; the secondary objective was to quantify group differences in [Formula: see text]o2VAT response. Methods: Fifty-two preterm-born and 151 term-born participants were randomly assigned (1:1) to 16 weeks of aerobic exercise training (n = 102) or a control group (n = 101). Cardiopulmonary exercise tests were conducted before and after the intervention to measure [Formula: see text]o2PEAK and the [Formula: see text]o2VAT. A prespecified subgroup analysis was conducted by fitting an interaction term for preterm and term birth histories and exercise group allocation. Measurements and Main Results: For term-born participants, [Formula: see text]o2PEAK increased by 3.1 ml/kg/min (95% confidence interval [CI], 1.7 to 4.4), and the [Formula: see text]o2VAT increased by 2.3 ml/kg/min (95% CI, 0.7 to 3.8) in the intervention group versus controls. For preterm-born participants, [Formula: see text]o2PEAK increased by 1.8 ml/kg/min (95% CI, -0.4 to 3.9), and the [Formula: see text]o2VAT increased by 4.6 ml/kg/min (95% CI, 2.1 to 7.0) in the intervention group versus controls. No significant interaction was observed with birth history for [Formula: see text]o2PEAK (P = 0.32) or the [Formula: see text]o2VAT (P = 0.12). Conclusions: The training intervention led to significant improvements in [Formula: see text]o2PEAK and [Formula: see text]o2VAT, with no evidence of a statistically different response based on birth history. Clinical trial registered with www.clinicaltrials.gov (NCT02723552).

    Fetal growth restriction (FGR) leading to low birth weight (LBW) is a major cause of neonatal morbidity and mortality worldwide. Normal placental development involves a series of highly regulated processes involving a multitude of hormones, transcription factors, and cell lineages. Failure to achieve this leads to placental dysfunction and related placental diseases such as pre-clampsia and FGR. Early recognition of at-risk pregnancies is important because careful maternal and fetal surveillance can potentially prevent adverse maternal and perinatal outcomes by judicious pregnancy surveillance and careful timing of birth. Given the association between a variety of circulating maternal biomarkers, adverse pregnancy, and perinatal outcomes, screening tests based on these biomarkers, incorporating maternal characteristics, fetal biophysical or circulatory variables have been developed. However, their clinical utility has yet to be proven. Of the current biomarkers, placental growth factor and soluble fms-like tyrosine kinase 1 appear to have the most promise for placental dysfunction and predictive utility for FGR.
