Nipple Pain in Breastfeeding Mothers: Incidence, Causes and Treatments

Predictors associated with night sleep disturbance among breastfeeding women

OBJECTIVE

The aim of this study was to investigate the incidence of somnological disorders among Kazakhstani women who breastfeed and to assess the association of this phenomenon with some medical and social characteristics.

METHODS

The authors used the standardized questionnaire of A.M. Vein and Y.I. Levin to assess nocturnal sleep among 1101 breastfeeding women in the Republic of Kazakhstan, applied Pearson's chi-square test to study the correlation between sleep disturbances and duration of breastfeeding, and multiple logistic regression to assess the influence of various medical and social factors on somnological disorders. Data collection occurred in February 2023.

RESULTS

On average, 80% of breastfeeding women (ranging from 79% to 85.9%) experienced some form of nocturnal sleep disorders, with no significant association found between these disorders and breastfeeding duration (p = 0.234), while urban residence, history of operative delivery, child's health issues, and low satisfaction levels with various aspects were associated with over twofold increased odds of experiencing sleep disorders (p ≤ 0.05).

CONCLUSIONS

The elevated prevalence of nocturnal sleep disorders among breastfeeding Kazakhstani women serves as a risk indicator for adverse health outcomes, with predictors including place of residence, obstetric complications, child health issues, and satisfaction levels with social conditions and personal expression opportunities.

COMT Variants are Associated With Breast and Nipple Pain

Estimates suggest that only 24.9% of infants born in 2019 were exclusively breastfed before 6 months of age, despite the known health benefits of exclusive breastfeeding. Breast and nipple pain is one of the primary determinants of exclusive breastfeeding. Environmental contributions to breastfeeding success have been reported extensively in the literature, but the contribution(s) of maternal genetics has yet to be discovered. The purpose of the study was to identify an association between pain and lactation-related gene variants with exclusive breastfeeding determinants. We selected 4 genes having single nucleotide polymorphisms (SNPs) with potential functional significance in breastfeeding and pain: prolactin receptor (PRLR), oxytocin receptor (OXTR), catechol-O-methyltransferase (COMT), and milk fat globule epidermal growth factor and factor V/VIII domain containing (MFGE8). We performed a cross-sectional secondary analysis of a longitudinal randomized controlled trial study, Promoting Self-Management of Breast and Nipple Pain with Biomarkers and Technology for Breastfeeding Women (NCT05262920). Breast and nipple pain, perceived insufficient milk, and breastfeeding self-efficacy were examined using total scale scores for the Brief Pain Inventory, Visual Analog Scale, H&H Lactation Scale, and the Breastfeeding Self-efficacy Scale-short form, respectively. Of the candidate genes examined, SNPs within COMT were significantly associated with breastfeeding-related outcomes. Specifically, COMT rs4633 and rs4680 minor allele carriers (T, A) reported higher breast and nipple pain intensity than women homozygous for the major allele (C, G). COMT is the most widely researched "pain gene" and has been linked to cold, postoperative, and postpartum pain. This study is the first to identify a contribution of COMT variants to breast and nipple pain and, as a result, to breastfeeding exclusivity. PERSPECTIVE: Two SNPs in the pain gene COMT are associated with breast and nipple pain. Clinically, a minor allele in COMT rs4633 and rs4680 may increase a woman's rating of moderate breast and nipple pain. TRIAL REGISTRATION: PROMPT was registered in ClinicalTrials.gov (protocol #NCT05262920).

Geospatial variation of exclusive breastfeeding and its determinants among mothers of infants under 6 months in Ethiopia: spatial and geographical weighted regression analysis

BACKGROUND

Exclusive breastfeeding (EBF) is a major public health problem in Ethiopia. However, the spatial variation of EBF and the associated factors have not been studied as much as we have searched. This study aimed at assessing geospatial variation and the predictors of EBF using geographically weighted regression.

METHODS

A cross-sectional study was conducted using the 2019 Mini-Ethiopian Demographic and Health Survey data set. The study used a total weighted sample of 548 infants. Hotspot spatial analysis showed the hotspot and cold spot areas of EBF. The spatial distribution of EBF was interpolated for the target population using spatial interpolation analysis. SaTScan V.9.6 software was used to detect significant clusters. Ordinary least squares regression analysis identified significant spatial predictors. In geographically weighted regression analysis, the effect of predictor variables on the spatial variation of EBF was detected using local coefficients.

RESULTS

The weighted prevalence of EBF in Ethiopia was 58.97% (95% CI 52.67% to 64.99%), and its spatial distribution was found to be clustered (global Moran's I=0.56, p<0.001). Significant hotspot areas were located in Amhara, Tigray, Southern Nations, Nationalities, and Peoples' Region, and Somali regions, while significant cold spots were located in Dire Dawa, Addis Ababa and Oromia regions. Kulldorff's SaTScan V.9.6 was used to detect significant clusters of EBF using a 50% maximum cluster size per population. The geographically weighted regression model explained 35.75% of the spatial variation in EBF. The proportions of households with middle wealth index and married women were significant spatial predictors of EBF.

CONCLUSION

Middle wealth index and married women were significant spatial predictors of EBF. Our detailed map of EBF hotspot areas will help policymakers and health programmers encourage the practice of EBF in hotspot areas and set national and regional programmes focused on improving EBF in cold spots by considering significant predictor variables.

Laid-back breastfeeding: knowledge, attitudes and practices of midwives and student midwives in Ireland

BACKGROUND

Despite concerted efforts by policy developers, health professionals and lay groups, breastfeeding rates in Ireland remain one of the lowest in world, with 63.6% of mothers initiating breastfeeding at birth, dropping to 37.6% of mothers breastfeeding exclusively on hospital discharge. Nipple trauma and difficulties with baby latching are major contributors to the introduction of formula and discontinuation of breastfeeding. Research shows laid-back breastfeeding (LBBF) significantly reduces breast problems such as sore and cracked nipples, engorgement, and mastitis as well as facilitating a better latch. Although the benefits of LBBF are well documented, this position does not seem to be routinely suggested to mothers as an option when establishing breastfeeding. This study aims to determine midwives' and student midwives' knowledge, attitudes, and practices of using laid-back breastfeeding in Ireland.

METHOD

A cross-sectional descriptive survey distributed to midwives and student midwives in three maternity hospitals in Ireland and two online midwifery groups based in the Republic of Ireland, during June, July, and August 2021.

RESULTS

Two hundred and fifty-three valid responses were received from nine maternity units. Most participants (81.4%) were aware of laid-back breastfeeding. However, only 6.8% of respondents cited it as the position they most frequently use. Over one-third (38.34%) had never used this position with mothers. Those more likely to suggest LBBF had personal experience of it, were lactation consultants or working towards qualification, or had participated in specific education about LBBF. Barriers included lack of education, confidence, time, and experience. Further issues related to work culture, a tendency to continue using more familiar positions and concerns about mothers' anatomy and mothers' unfamiliarity with LBBF.

CONCLUSION

Although there was a high level of awareness of laid-back breastfeeding among midwives and student midwives, there are challenges preventing its use in practice. Education specifically related to using LBBF in practice is required to overcome the barriers identified. A greater understanding of mothers' and babies' intrinsic feeding capacities may give midwives more confidence to recommend this method as a first choice, potentially leading to more successful breastfeeding establishment and maintenance.

Breastfeeding-related Pain, Sensory Over-responsiveness, and Exclusive Breastfeeding at 6 Months: A Prospective Cohort Study

BACKGROUND

Exclusive breastfeeding (EBF) is recommended for the first 6 months of life, yet EBF rates at 6 months (T3) in most developed countries are low. Painful and nonpainful sensory stimuli processing is linked, and while pain has been suggested to restrict breastfeeding, its coupling with sensory over-responsiveness (SOR) in relation to breastfeeding has not yet been reported.

OBJECTIVE

We aimed to explore whether breastfeeding-related pain, SOR, and general pain sensitivity predict nonexclusive breastfeeding (NEBF) at T3.

STUDY DESIGN

In this prospective study, participants were recruited at 2 days postpartum (enrollment). For the assessment of breastfeeding-related pain, participants completed the visual analogue scale and the Short-Form McGill Pain Questionnaire at enrollment, and at 6 weeks after birth. At T3, they completed the Pain Sensitivity Questionnaire and the Sensory Responsiveness Questionnaire-Intensity Scale and then provided information about their breastfeeding status. Participants were divided into two groups accordingly: EBF and NEBF.

RESULTS

A total of 164 participants were reached at T3: EBF (n = 105) and NEBF (n = 59). The incidence of SOR was significantly higher among NEBF compared with EBF participants (25.4% vs. 11.4%; p = .020). Between enrollment and 6 weeks after birth, 72.3% of the EBF participants had reported a ≥30% pain reduction, compared with 44.8% of the NEBF participants (p = .001). Logistic regression modeling revealed that both breastfeeding-related pain reduction and SOR predicted NEBF at T3 (p < .001), indicating a 3.2 times (p = .001) and 2.5 times (p = .041) odds ratio for NEBF, respectively.

CONCLUSIONS

SOR and sustained breastfeeding-related pain predict NEBF at T3 and may emerge as substantial breastfeeding barriers.

The effect of interventions on flat and inverted nipple on breastfeeding: A systematic review

BACKGROUND

Some methods have been developed to solve flat and/or inverted nipple problems. This study aimed to examine the effects of flat and/or inverted nipple interventions on nipples and breastfeeding.

METHODS

Before initiating the review, the protocol was registered in the 'PROSPERO' database. This study was based on the PRISMA-P guideline. Seven databases (Web of Science, PubMed, ScienceDirect, Scopus, The Cochrane Library, TÜBİTAK Ulakbim and Google Scholar) were searched, and nine studies were included in this review.

RESULTS

Hoffman's exercise, the inverted syringe method, and the nipple exercise was quite effective in increasing breastfeeding success. The rate of exclusive breastfeeding in the first, third, and sixth months of mothers followed up with postpartum multidimensional visits was found to be significantly higher in the intervention group than in the control group (p < 0.05). A study in which a rubber band was applied with the help of an injector on flat and inverted nipples showed that 63% of mothers on the third day and all of them in the first month were able to breastfeed without a rubber band. Hoffman's exercise, the inverted syringe technique, and rubber bands corrected the flat and/or inverted nipple. There were studies reporting complications as a result of nipple interventions.

CONCLUSIONS AND IMPLICATIONS

It is necessary to disseminate the information that breastfeeding of mothers with flat and/or inverted nipples can be sustained with various interventions. Furthermore, it is believed that providing mothers with a chance to choose the interventions, and thus, the compliance of mothers to the intervention with the method of their choice may increase the success of the intervention.

Comparative Effectiveness of Olive Oil and Breast Milk on Nipple Soreness in Breastfeeding Mothers

Background: Breastfeeding has health benefits for both mothers and children. Nipple problems may result in the child being weaned prematurely before the recommended 6 months minimum period of exclusive breastfeeding. Purposes of the Study: The study aimed to compare the effectiveness of topically applying olive oil and breast milk in treating nipple pain and soreness in breastfeeding mothers during the early postpartum period. Methods: A quasi-randomized controlled trial was conducted in a maternity ward of a medical center in northern Taiwan. Eighty breastfeeding mothers were recruited, and randomly assigned to the olive oil or breast milk group. Visual analogue pain scale (intensity of nipple pain) and nipple soreness scores were collected at 24, 48, and 72 hours after delivery. Differences in postintervention outcomes between groups were examined using the Generalized Estimating Equation model. Results: The results indicated that both olive oil and breast milk groups reported a significant increase in the intensity of nipple pain and nipple soreness at 24, 48, and 72 hours after delivery. However, differences in the outcome measurements between olive oil and breast milk groups were statistically insignificant at p-value >0.05. Conclusion: This study found that olive oil had similar effects on nipple pain and soreness to breast milk. In addition, most breastfeeding mothers provided positive feedback on using olive oil. Olive oil can be a safe, accessible, and alternative choice for breastfeeding mothers in treating nipple pain and soreness, especially early in the breastfeeding period. The Clinical Trail Registration Number: NCT03568370.

Severity and prevalence of ankyloglossia-associated breastfeeding symptoms: A systematic review and meta-analysis

AIM

To evaluate breastfeeding symptoms associated with ankyloglossia/tongue-tie.

METHODS

Databases included PubMed, Embase, CINAHL, PsycINFO, Web of Science, and Google Scholar. Eligible studies reported baseline breastfeeding symptoms/severity from tongue-tied infants. Two reviewers independently screened studies, extracted data, and assessed quality. Low-quality studies were excluded. Main outcomes were weighted mean severity scores for dyads with ankyloglossia relative to reference values for successful breastfeeding. Meta-analyses used inverse-variance-weighted random-effects models.

RESULTS

Of 1328 screened studies, 39 were included (5730 infants with ankyloglossia). The mean LATCH score for patients with untreated ankyloglossia, 7.1 (95% CI: 6.7-7.4), was significantly below the good-breastfeeding threshold. The mean Infant Breastfeeding Assessment Tool score, 10.0 (8.2-11.7), was not significantly below the good-breastfeeding threshold. The mean Infant-Gastroesophageal Reflux Questionnaire-Revised score, 18.2 (10.5-26.0), was consistent with gastroesophageal reflux disease. The mean Breastfeeding Self-Efficacy Scale-Short Form score, 43.7 (39.3-48.1), indicated significant risk of cessation of exclusive breastfeeding within 1-3 months. Mean nipple pain was 4.9 (4.1-5.7) on a 0-10 scale, greater than typical scores for breastfeeding mothers without nipple damage. Total prevalence of breastfeeding difficulties was 49.3% (95% CI: 47.3-51.4%). Early, undesired weaning occurred in 20.3% (18.5-22.2%) of cases before intervention.

CONCLUSION

Ankyloglossia is adversely associated with breastfeeding success and maternal well-being.

Breastfeeding Symptoms with Tongue- and Lip-Tie

PURPOSE

The aims of this study were to describe maternal and infant symptoms relative to tongue- and lip-tie severity and describe changes in symptoms and feeding efficiency from pre- to post-frenotomy.

STUDY DESIGN AND METHODS

A one-group pre- and post-intervention study design was used. Data from a dental practice were collected from medical records of infants less than 1 year old who underwent a frenotomy procedure for tongue- and/or lip-tie. Infant and maternal symptoms were compared with severity of tongue- and lip-tie using binary logistic regression. Wilcoxon Signed Rank test compared pain scores and feeding duration pre- and post-frenotomy. Linear regression compared total number of symptoms reported pre-frenotomy with tongue- and lip-tie severity.

RESULTS

N = 121 dyads were included. More severe classifications of tongue- and lip-tie were significantly associated with certain infant and maternal symptoms pre-frenotomy. Improvements were noted in all reported infant symptoms post-frenotomy. Feeding duration times significantly decreased post-frenotomy.

CLINICAL IMPLICATIONS

Infants and mothers experience problematic symptoms with feeding associated with tongue- and lip-tie. Nurses are the primary care providers during postpartum and should be alert to signs and symptoms that may suggest oral restrictions. Early evaluation and involvement of feeding experts may improve the breastfeeding experience of the dyad.

Association of Milk Secretion Volume with Nipple Pain: A Prospective Hypothesis Verification Study

Background: Many mothers stop breastfeeding due to nipple pain, which is experienced when the baby sucks the mother's nipples during breastfeeding. Objective: To verify how nipple pain during breastfeeding is associated with nipple perfusion and volume of milk secretion. Study Design: Prospective hypothesis verification study. Methods: Fifty-nine lactating women who delivered at term were enrolled. The CS Probe S and laser Doppler ALF21 were used to measure perfusion, and PowerLab 2/26 and LabChart 8 were used to analyze perfusion. The difference in the infant's weight (g) before and after breastfeeding was used to measure milk secretion. Results: The participants' mean age (± standard deviation) was 30.88 ± 3.77 years. Although 80-90% of participants had proper breastfeeding posture and infant attachment, 34 (57.6%) and 30 (42.4%) mothers experienced nipple pain on postpartum days 1 and 4, respectively. For postpartum days 1 and 4, the group with nipple pain exhibited significantly less nipple perfusion than the group without pain. Milk secretion was lower in the group with nipple pain on postpartum day 4 than in the group without pain, although this was not statistically significant. The reduction in nipple perfusion did not differ significantly between the high (75%) and low secretion groups (25%) and between the nipple trauma and nontrauma groups. However, the low secretion group and nipple trauma group had larger reductions in nipple perfusion. Conclusion: Assessing the amount of milk secretion can provide a new perspective on preventive care for nipple pain and trauma.

Does neonatal ankyloglossia interfere in the growth of infants during the first 6 months of life? A case series nested in a cohort study

BACKGROUND

Ankyloglossia is commonly reported as one of the major causes of breastfeeding difficulty. There is a lack of research on infant growth and latching performance with clinical measures.

CASES PRESENTATION

We describe a series of eight clinical cases (three female and five male infants) in a specialized breastfeeding center in a tertiary hospital in Northeast Brazil. The mothers were of mixed race and ranged from 13 to 41 years of age. Ankyloglossia was diagnosed within the first 48 hours after delivery. We measured the standards of growth, the mothers' perception of breastfeeding, and a pain indicator, and performed an assessment of breastfeeding. The regularity of breastfeeding was maintained despite the early diagnosis of ankyloglossia. Growth indicators were not affected in the sixth month in any of the babies, with only one measuring below expectations in the third month, with no impact on general health.

CONCLUSIONS

In the cases reported in this paper, the infants overcame the initial difficulties in breastfeeding and maintained their normal growth course in the first 6 months of life.

Effective breastfeeding technique and associated factors among lactating mothers in Gidan District, North-East, Ethiopia: a community-based cross-sectional study

OBJECTIVE

To assess effective breastfeeding technique (EBT) and associated factors among lactating mothers in Gidan District, North-East Ethiopia.

DESIGN

A community-based cross-sectional study.

SETTING

Gidan District, North-East Ethiopia.

PARTICIPANTS

A total of 786 lactating mothers were included between 30 March and 29 April 2021.

OUTCOME

EBT.

METHODS

A multistage sampling technique was employed to recruit participants. Pretested interviewer-administered questionnaires and an observational checklist were used to collect the data. Individual scores of three variables about breast feeding, namely positioning, attachment and suckling, were computed to generate the outcome variable, that is, breastfeeding technique. Binary logistic regression analyses were carried out to determine the association between independent variables and EBT. Statistical significance was declared at a value of p≤0.05 with a corresponding 95% CI.

RESULTS

Overall, the prevalence of EBT was 42.9% (326/760). Having antenatal care follow-up (adjusted OR (AOR)=1.75; 95% CI 1.10 to 2.77), delivering at health institutions (hospital AOR=2.85; 95% CI 1.22 to 6.66 and health centre AOR=2.15; 95% CI 1.25 to 3.68), and receiving postpartum home visits by the health extension workers (HEWs) (AOR=2.12; 95% CI 1.55 to 2.92) were significantly associated with the practice of EBT.

CONCLUSION

The study showed that the prevalence of EBT was low. The finding highlights the importance of promoting utilisation of antenatal care follow-up, institutional delivery and postpartum home visits by HEWs, which play a substantial role in promoting EBT.

The inverted syringe technique for management of inverted nipples in breastfeeding women: a pilot randomized controlled trial

Background

Women with inverted nipples may struggle with breastfeeding and may stop exclusive breastfeeding before six months. The use of an inverted syringe to evert the nipples was successful in achieving high rates of infant latching and exclusive breastfeeding in case series but has not been tested in clinical trials. This open label, parallel group, randomized clinical trial investigated whether the use of the inverted syringe technique in women with inverted nipples would increase exclusive breastfeeding rate at one month, as compared to standard care.

Methods/Design

Between June 2018 and January 2020, healthy pregnant women (N=54) with grades 1 or 2 inverted nipples were randomly allocated to standard care or to an experimental group that used the inverted syringe technique to evert the inverted nipple prior to every breastfeeding. The primary outcome measure was the rate of exclusive breastfeeding at one month. Secondary outcomes included the rates of exclusive breastfeeding at three and six months, any breastfeeding at one, three, and six months, nipple eversion, successful infant latching, breastfeeding-associated complications, maternal satisfaction with breastfeeding, maternal quality of life, and adverse events. Descriptive and bivariate analyses were conducted according to the intention to treat principle.

Results

Participants in the experimental group were less likely to be exclusively breastfeeding at one (RR = 0.65, 95% CI: 0.44, 0.95; n = 47), and at three months (RR = 0.66, 95% CI: 0.47, 0.91; n = 45), or to practice any breastfeeding at six months (RR = 0.54, 95% CI: 0.34, 0.87; n = 44). Only 14.3% of women in the experimental group complied with the use of the inverted syringe during the first month. Breast pump and breastfeeding-associated complications were more commonly reported in the control group (p < 0.05 for both). Both groups had similar rates of nipple eversion, successful infant latching, and similar satisfaction with breastfeeding and quality of life issues.

Conclusion

The inverted syringe technique was not associated with improvement in breastfeeding outcomes of women with inverted nipples. Larger clinical trials are needed to confirm our findings.

Effect of Frenotomy on Maternal Breastfeeding Symptoms and the Relationship Between Maternal Symptoms and Problematic Infant Feeding

The relationship between maternal symptoms and problematic infant feeding in the context of tongue-tie is unknown. In a sample of infants with tongue-tie undergoing frenotomy and their mothers, the aims of this study were to: (1) describe changes in maternal symptoms pre- and post-frenotomy, and (2) evaluate the relationships between maternal symptoms and symptoms of problematic feeding pre- and post-frenotomy. Mother-infant dyads were recruited from 1 pediatric dental office between July and November 2020. The sample included 102 mother-infant dyads; 84 completed the follow-up survey. Maternal symptoms of painful and difficult latch, creased/cracked nipples, bleeding, or abraded nipples, chewing of the nipple, and feelings of depression were significantly less common after tongue-tie revision. Poor latch onto the breast was associated with feeding difficulties at both time points. Frenotomy resulted in a decrease of symptoms in breastfeeding mothers. Maternal symptoms and feeding problems persisting post-frenotomy warrant further evaluation.

Considerations for lactation with Ehlers-Danlos syndrome: a narrative review

Background

Ehlers-Danlos syndrome (EDS) is a rare genetic connective tissue condition that is poorly understood in relation to lactation. As diagnostic methods improve, prevalence has increased. EDS, a disorder that impacts connective tissue, is characterized by skin extensibility, joint hypermobility, and fragile tissue which can affect every organ and body system leading to complications during pregnancy, delivery, and the postpartum period. Traits of this disease can cause mild to severe physiologic and functional obstacles during lactation. Unfortunately, there is little clinical evidence and minimal guidance for lactation management, and providers may feel uncomfortable and hesitant to address these concerns with patients due to a lack of readily available resources on the subject and inexperience with such patients. This narrative review describes and discusses the types of EDS, identifying symptoms, considerations, and precautions for care providers to implement during lactation and breastfeeding.

Methods

An electronic search of relevant citations was conducted using the databases Cochrane, PubMed, and Google Scholar from 1 January 2000 to 1 November 2021. Search terms used were Ehlers-Danlos syndrome, Hypermobility Syndrome, breastfeeding, lactation, breastmilk expression, breastmilk collection, human milk expression, human milk collection, and infant feeding. The search of these databases yielded zero results. As no research articles on EDS were directly related to lactation, this narrative review includes articles found that related to the health of mothers relevant to maternal function during lactation.

Discussion

For the healthcare provider, identifying characteristics of EDS can improve the management of lactation challenges. Mothers may experience generalized symptoms from gastrointestinal distress to fatigue or chronic pain, while they also may suffer from more specific joint complaints and injuries, such as dislocations / subluxations, or skin fragility. Such obstacles can generate impediments to breastfeeding and create unique challenges for breastfeeding mothers with EDS.

Unfortunately, new mothers with these symptoms may have them overlooked or not addressed, impacting a mother’s ability to meet her breastfeeding intentions. While there are some published research manuscripts on EDS and pregnancy, there is a lack of information regarding breastfeeding and lactation. Additional research is needed to help guide EDS mothers to achieve their breastfeeding intentions.

Re-thinking lactation-related nipple pain and damage

Nipple pain is a common reason for premature cessation of breastfeeding. Despite the benefits of breastfeeding for both infant and mother, clinical support for problems such as maternal nipple pain remains a research frontier. Maternal pharmaceutical treatments, and infant surgery and bodywork interventions are commonly recommended for lactation-related nipple pain without evidence of benefit. The pain is frequently attributed to mammary dysbiosis, candidiasis, or infant anatomic anomaly (including to diagnoses of posterior or upper lip-tie, high palate, retrognathia, or subtle cranial nerve abnormalities). Although clinical protocols universally state that improved fit and hold is the mainstay of treatment of nipple pain and wounds, the biomechanical parameters of pain-free fit and hold remain an omitted variable bias in almost all clinical breastfeeding research. This article reviews the research literature concerning aetiology, classification, prevention, and management of lactation-related nipple-areolar complex (NAC) pain and damage. Evolutionary and complex systems perspectives are applied to develop a narrative synthesis of the heterogeneous and interdisciplinary evidence elucidating nipple pain in breastfeeding women. Lactation-related nipple pain is most commonly a symptom of inflammation due to repetitive application of excessive mechanical stretching and deformational forces to nipple epidermis, dermis and stroma during milk removal. Keratinocytes lock together when mechanical forces exceed desmosome yield points, but if mechanical loads continue to increase, desmosomes may rupture, resulting in inflammation and epithelial fracture. Mechanical stretching and deformation forces may cause stromal micro-haemorrhage and inflammation. Although the environment of the skin of the nipple-areolar complex is uniquely conducive to wound healing, it is also uniquely exposed to environmental risks. The two key factors that both prevent and treat nipple pain and inflammation are, first, elimination of conflicting vectors of force during suckling or mechanical milk removal, and second, elimination of overhydration of the epithelium which risks moisture-associated skin damage. There is urgent need for evaluation of evidence-based interventions for the elimination of conflicting intra-oral vectors of force during suckling.

Case Report of the Management of Milk Blebs

The formation of a milk bleb during breastfeeding is frequently associated with nipple pain that may affect the breastfeeding success of the mother-infant dyad. Early cessation of breastfeeding may occur when pain is ongoing. Timely evaluation and diagnosis and effective management are imperative to prevent tissue damage and lingering symptoms. In this case report, we evaluate the unique challenges of the diagnosis and management of milk blebs, including nonpharmacologic and pharmacologic treatment.

Exploring women's perceptions of pain when breastfeeding using online forums

BACKGROUND

Despite numerous benefits, many mothers stop breastfeeding soon after birth. A common reason for this is the experience of pain or discomfort. One resource which women use to share their breastfeeding challenges and seek support are online forums. This study aimed to collect data from online forums to explore 1) usage of forums as social support for breastfeeding-related pain; 2) experiences of breastfeeding-related pain; 3) perceptions and strategies to deal with breastfeeding-related pain; and 4) the impact of pain on breastfeeding duration.

METHODS

Data was gathered through searches of online forums based in the UK and USA: Netmums, What to Expect and Mumsnet using key terms: 'painful breastfeeding' and 'sore breastfeeding'. Data extraction took place in July 2018 and included posts made between 2012 and 2018. Data included 123 posts and 193 replies, analysed using thematic analysis.

RESULTS

The first theme identified was 'variation in types of pain', highlighting the variety of painful experiences and their descriptions. In particular, this theme reveals the large variety of different types of pain women experience at different stages throughout their breastfeeding journey, as well as the different pain characteristic they focus on in the description of their experience (i.e., location, sensory or physical aspects). Secondly, the theme 'perceived causes and explanations for pain' revealed how women interpret pain experiences either due to a recognised condition or behavioural cause. The third theme 'cessation of breastfeeding related to pain' identified. How women experience both physical and psychological struggles (e.g., guilt) related to breastfeeding cessation, with pain being a main factor in considering cessation of breastfeeding. Finally, the theme 'shared experiences and support' identified women's strong need for both practical and emotional support to deal with pain. Many women look for this support through the knowledge exchange offered on the online forums.

CONCLUSIONS

Pain was a key reason for breastfeeding cessation, commonly associated with strong feelings of guilt. The online forums provide a unique form of social support for breastfeeding women to find ways to cope with the pain, while highlighting the urgent need for more appropriate antenatal education on realistic expectation surrounding breastfeeding.

Breast Milk Production in Women Who Use Nipple Shields for Persistent Nipple Pain

OBJECTIVE

To examine relationships between nipple pain scores and 24-hour milk production volumes, breastfeeding and pumping frequencies, and breastfeeding duration in women using nipple shields for persistent nipple pain.

DESIGN

Secondary outcome analysis of a prospective cohort study.

SETTING

Research laboratory and participants' homes.

PARTICIPANTS

Twenty-five breastfeeding women (6 ± 4 weeks after birth) who used nipple shields for persistent nipple pain.

METHODS

We conducted a randomized trial to investigate the primary outcome of milk transfer with and without nipple shields among participants with and without nipple pain. Here, we report secondary outcomes of associations between 24-hour milk production, breastfeeding and pumping frequencies, breastfeeding durations, and intake in participants using a nipple shield for nipple pain. Participants completed demographic, health and breastfeeding questionnaires and, at two monitored breastfeeding sessions, completed a pain visual analogue scale and Brief Pain Inventory-Short Form (BPI-SF; total and subscale scores for pain interference with General Activity, Mood, Sleep, and Breastfeeding). Milk production (milliliters per 24 hours), feed volumes, and percentage of available milk removed were calculated from data and milk samples obtained by participants over one 24-hour period and at study visits. Participants logged 24-hour data on a customized research website. We used descriptive statistics as well as simple and multiple linear regression for analyses.

RESULTS

Milk production and feeding duration were not associated with nipple pain scores (visual analogue scale: p = .80, BPI-SF: p = .44). An increase in BPI-SF Breastfeeding subscale score of 1 unit, indicating pain interference with breastfeeding, was associated with a 0.28 decrease in breastfeeding frequency (p = .02) and an 18.8-ml decrease in 24-hour breastfeeding intake (p = .04).

CONCLUSION

Persistent nipple pain was associated with reduced breastfeeding frequency; therefore, continuing professional support is required to ensure adequate milk removal and pain management.

The impact of maternal eating disorders on breastfeeding practices: a systematic review

Breastfeeding is an effective way to protect and promote the health of the infant and mother. Cultural, social, economic, medical, or psychological factors might interfere with successful breastfeeding. Therefore, maternal eating disorders (EDs) may have detrimental effects on the decision of breastfeeding initiation and on its continuation. There is limited knowledge about the breastfeeding practices of mothers with EDs. We performed a systematic review to generate more evidence in this area. A search was conducted in PubMed and PsycINFO, and several journals were hand searched for relevant publications. Of N = 3904 hits, 13 full texts were included in the qualitative analysis. The findings on total duration of BF between mothers with and without EDs were mixed, but women with EDs showed more negative experiences and emotional problems during BF. There was not enough evidence to conclude on breastfeeding initiation, or on the duration of exclusive breastfeeding. Maternal EDs might have a negative impact on BF practices with possible negative effects on the maternal-child feeding environment. Further studies with comparable data and information on the women's partners' attitudes about breastfeeding are needed.

The effect of vernix caseosa in preventing nipple problems among early postpartum women: A randomized-controlled single-blind clinical trial☆

BACKGROUND AND PURPOSE

Vernix caseosa, a natural substance similar to mother's milk with protective effects on the skin, might be effective in preventing nipple problems. The purpose of this study was to examine the potential efficacy of vernix caseosa compared to the conventional use of mother's milk in the prevention of postpartum nipple problems.

MATERIALS AND METHODS

This randomized, controlled, single-blind experimental study involved 64 primipara mothers who underwent cesarean section and were randomly and equally divided between the vernix caseosa group and the mother's milk group. All mothers received nipple care four times daily during the first postpartum week. Data were collected using personal information and nipple monitoring forms.

RESULTS

The incidence of nipple pain, rashes, and an abnormal appearance was similar in both groups on the first day postpartum (p = 0.132, p = 0.516, and p = 0.132, respectively), and none of the mothers had nipple cracks. On the seventh day, mothers in the vernix caseosa group had significantly less pain (p = 0.042), significantly reduced rash (p = 0.048), significantly higher satisfaction (p = 0.023), and no nipple cracks.

CONCLUSION

Nipple care with vernix caseosa is more effective than with mother's milk in preventing postpartum nipple pain, rashes, and cracks.

Nipple shield use does not impact sucking dynamics in breastfeeding infants of mothers with nipple pain

Nipple shields (shield) may reduce pain during breastfeeding, but the impact on infant sucking dynamics is not known. We examined the effects of shield use on sucking dynamics, milk removal and nipple pain in two groups of breastfeeding dyads: pain group (PG): shield used for nipple pain; comparison group (CG): no breastfeeding difficulties. Twenty PG (6 ± 4 weeks postnatal) and 28 CG dyads (8 ± 6 weeks postnatal) attended 2 monitored breastfeeding sessions with shield use randomised. Within-subject outcomes were compared. PG: shield use did not affect intra-oral vacuum (peak p = 0.17, baseline p = 0.59), sucking frequency (p = 0.20) or milk transfer (40 mL vs 48 mL, p = 0.80; percentage of available milk removed (PAMR) 55% vs 57%, p = 0.88), and reduced McGill pain scores (p = 0.012). CG: shield use increased non-nutritive sucking (10% more, p = 0.049), and reduced nutritive sucking (18% less, p = 0.017) and milk transfer (63 mL vs 31 mL p < 0.001, PAMR 65% vs 36% p < 0.001). For both groups, feeding duration increased by 2 min (p < 0.0001) and non-nutritive portions of the feed increased with shield use.Conclusion: Nipple shield use improved maternal comfort and did not impact milk removal or sucking strength in PG, but significantly reduced milk transfer and nutritive sucking in CG. What is Known: • Mothers report that nipple shields reduce nipple pain and enable continued breastfeeding. • Concerns that nipple shield use may reduce milk transfer and alter infant sucking patterns are based on limited published evidence. What is New: • Nipple shield use is associated with a 25% reduction in pain scores in breastfeeding mothers with chronic nipple pain. • Milk transfer is not reduced in dyads that regularly use a shield for chronic nipple pain. • Intra-oral vacuums are not impacted by nipple shield use in mothers experiencing pain.

It's Not Yeast: Retrospective Cohort Study of Lactating Women with Persistent Nipple and Breast Pain

Introduction: Health care providers treating lactating women for nipple and breast pain often attribute symptoms to Candida albicans infection. However, multiple other conditions may present with pain, erythema, and pruritis. We explored the experience of a breastfeeding medicine practice that received referrals for patients failing antifungal therapy and who desired further evaluation for alternative diagnoses. Materials and Methods: We conducted a retrospective chart review of breastfeeding women referred for evaluation of "yeast" to a breast surgery/breastfeeding medicine practice from July 2016 to August 2019. Results: Twenty-five women met inclusion criteria. Median age was 33 (range 24-43) and median months postpartum was 4 (range 0.5-18). All 25 women reported minimal to no improvement on oral and/or topical antifungal therapy. In addition to history and examination, milk culture was obtained in four women, punch biopsy in one, and core needle biopsy in one. No woman was confirmed to have a diagnosis of Candida. Diagnoses were changed to the following: subacute mastitis/mammary dysbiosis (n = 8), nipple bleb (n = 6), dermatitis (n = 6), vasospasm (n = 2), milk crust (n = 1), hyperlactation (n = 1), and postpartum depression (n = 1). Treatment included discontinuation of antifungal medication, as well as the following per individual diagnoses: antibiotics and probiotics; 0.1% triamcinolone cream; heat therapy; discontinuation of exclusive pumping; and antidepressant medication and counseling referral. All women experienced resolution of symptoms following revision of diagnosis and change in management (range 2-42 days). Conclusion: While persistent nipple and breast pain in breastfeeding is often attributed to Candida, this cohort demonstrates that providers should consider multiple other conditions in their differential diagnosis. Accurate, timely diagnosis is crucial, as pain is a risk factor for premature cessation of breastfeeding. Symptomatic resolution occurs on appropriate therapy.

Prevalence of Nipple Soreness at 48 Hours Postpartum

Background: Although most women start breastfeeding after delivery, difficulties often arise. One of the main reasons is nipple soreness, which contributes greatly to early cessation of breastfeeding. A soreness evaluation through validated scales, performed by health care professionals during the first few days, can contribute to improve breastfeeding and support for the mothers. Research Aim: Knowing the prevalence of nipple soreness during breastfeeding at 48 hours postpartum at the Infanta Cristina University Hospital (Madrid, Spain) through a cross-sectional descriptive study. Materials and Methods: The study took place between February and March 2019. A survey of 58 postpartum second day mothers was conducted including the Visual Analogue Scale (VAS) and Lactation Assessment Scale (LATCH) score for breastfeeding assessment. A descriptive analysis of secondary variables and subsequent bivariate inferential was performed for 95% confidence interval (CI). Results: The prevalence of nipple soreness observed is 97% (95% CI = 92-100%). It was found, significantly (p = 0.001), that the higher the score on LATCH, the lower the score on VAS and therefore the less pain. We found a relationship between women who were in skin-to-skin contact with their babies for 2 hours without interruption after birth and a higher pain score (p = 0.046). No other associations were found between VAS and other variables such as parity, type of birth, artificial milk supplements for the newborn, or using a pacifier. Conclusions: The high percentage of nipple soreness detected highlights that breastfeeding can be unpleasant in the first days after delivery. It is important to include in clinical practice the assessment of nipple soreness and the effectiveness of breastfeeding using validated scales.

Inverted Nipple Correction Techniques: An Algorithm Based on Scientific Evidence, Patients' Expectations and Potential Complications

BACKGROUND

Inverted nipple is a problem that affects a large number of women, with an aesthetic and functional repercussion. The literature is abundant in terms of techniques described, from the most conservative to the most aggressive. Although different techniques have been described to correct inverted nipples, there are no established algorithms to guide the surgeon in choosing the correct technique for each patient. Therefore, the objective of this paper is to present the first algorithm to simplify the inverted-nipple approach, based on the most recent scientific evidence and the patient's wishes.

METHODS

A bibliographic review on this pathology and available treatments was carried out to build an algorithm. Then, 47 patients consulting about inverted nipple concerns were included in this study. First, the patient's breastfeeding concerns were discussed. Once breastfeeding concerns were known, exploration of inverted nipple and assessment based on the degree of severity was done. Different techniques were proposed according to the degree of inverted nipple. Our technique was indicated in the most severe cases of retraction.

RESULTS

Forty-seven surgical and non-surgical procedures were carried out, resulting in excellent outcomes and high satisfaction rates. No complications or recurrence were observed after 1-year follow-up.

CONCLUSIONS

This is the first time an algorithm to simplify the approach of the inverted nipple has been proposed based on the degree of severity and lactation wishes. Choosing the right procedure for each patient will help the plastic surgeon in achieving great satisfaction and an excellent aesthetic result.

The effectiveness of the laid-back position on lactation-related nipple problems and comfort: a meta-analysis

Background

The importance of breastfeeding for maternal and child health is agreed upon worldwide. However, lactation-related nipple problems are common and are important factors affecting breastfeeding. Multiple studies recommended laid-back breastfeeding, but they are of various levels of quality, and the results are inconclusive.

Methods

We systematically searched the following twelve databases from inception to January 28,2020: Cochrane Library, EMBASE, Medline, Ovid, PubMed, Web of Science, CINAHL, Scopus, Chinese National Knowledge Infrastructure (CNKI), China Biology Medicine disc (CBM), WanFang, and VIP. All studies regarding laid-back breastfeeding or biological nurturing were considered, regardless of whether they were randomized controlled trials. Two trained investigators independently evaluated the quality of the selected articles and screened the data. All the data were analysed separately using Review Manager Version 5.3 and STATA/SE Version 15.1.

Results

A total of 12 studies involving 1936 groups of postpartum women and their newborns were included. The results of the meta-analysis showed that nipple pain (RR = 0.24; 95% CI 0.14, 0.40; p < 0.00001), nipple trauma (RR = 0.47; 95% CI 0.29, 0.75; p = 0.002) and correct latching position (RR = 1.22; 95% CI 1.11, 1.33; p < 0.0001) in the experimental groups were all better than those of the control groups, and the differences were statistically significant (p < 0.05), which indicates that the laid-back position has a positive effect on maternal breastfeeding. However, the results of position comfort showed that there was no statistical significance between the two groups (ES = 0.09; 95% CI -0.63, 0.81; p = 0.798).

Conclusion

Compared with traditional breastfeeding positions, the laid-back position has been proven to be related to a decreased incidence of nipple pain and nipple trauma and is seemingly conducive to the use of the correct latching position. It is suggested that the laid-back position is helpful in solving lactation-related nipple problems and can be recommended as a position for breastfeeding. However, no significant difference in position comfort was found between the two groups based on the current evidence, and further studies are still needed to validate these results due to the limitations of the included studies.

Postpartum Nipple Symptoms: Risk Factors and Dermatologic Characterization

Background: Nipple discomfort inhibits breastfeeding goals, particularly between 0 and 8 weeks postpartum (PP), and yet the specific dermatologic entities that contribute to nipple soreness have not been clearly delineated. Moreover, there remains a lack of evidence-based guidelines for nipple symptoms and skin diseases. Methods: A survey was distributed to 6-8-week PP women, 18-50 years of age, with an intent to exclusively or partially breastfeed ("at the breast" or "pump"). The study aimed to characterize nipple skin symptoms (pain and itching) and lesions (eczema, redness, cuts, or wounds) and any association between these nipple problems and past dermatologic history, breastfeeding outcomes, and the ability to meet her breastfeeding goals. Results: Findings paralleled Centers for Disease Control and Prevention (CDC) statistics with a 25% decline in breastfeeding rates between birth, 86.3% (189), and 6-8 weeks PP, 64.5% (145). By 6-8 weeks PP, exclusive "formula" and "exclusive feeding at the breast" showed the largest increase (+16.4%) and decrease (-22.9%), respectively. Although no significant difference was found in comparison of nipple problems to feeding methods or skin history, women who reported pumping or PP redness/eczema had higher odds ratios of a change in feeding practice, history of eczema, and sensitive skin. Strong pumping intentions were also associated with the highest risk of unmet breastfeeding goals. Conclusion: Regardless of feeding method, product, or provider use, PP nipple problems predominantly arose between 1 and 3 weeks PP. Clinical Trial Registration number 201901737.

A retrospective analysis of debridement in the treatment of chronic injury of lactating nipples

Treatment strategies for nipple injury are mainly based on aetiology. However, some damaged nipples do not heal after the aetiology was corrected. This study retrospectively analyses the effect of debridement for treating chronic injury of lactating nipples. The medical records on nipple injury management in the authors’ department from December 2015 to January 2020 were retrospectively analysed. A total of 167 patients were enrolled and grouped based on the presence or absence of nipple debridement. The difference in the healing effect, pain relief rate and recurrence rate of nipple injury between the two groups after 1 week was examined. The cure rate of nipple injury in the intervention group (54.3%) was significantly higher than in the control group (26.7%). In addition, the complete pain relief rate in the intervention group (48.1%) was significantly higher than in the control group (23.3%). However, the recurrence rates between the two groups (36.4% (16/44) vs. 34.8% (8/23)) had no statistically significant differences. For patients with no improvement after correction of the aetiology of the in the nipple damage, debridement can improve the healing environment of nipple breakage and thus relieve nipple pain.

Research Title: Factors Associated with Cessation of Exclusive Breastfeeding

Purpose

The study aimed to determine the prevalence of exclusive breastfeeding (EBF), measure the association between EBF and sociodemographic and obstetric characteristics of lactating mothers, and determine challenges of EBF.

Methods

The study was cross-sectional and was conducted in four primary health care centres (PHCCs) at Alehsa region in Saudi Arabia (SA). Lactating mothers coming to vaccinate their babies (0–6 months) were recruited. Sample size totalled 372, where 93 were randomly selected from each centre. Sociodemographic and obstetric characteristics of participants, breastfeeding (BF) status, and challenges of EBF were collected. Basic univariate descriptive statistics were conducted to explore the sociodemographic and obstetric characteristics, BF status and challenges of BF. Bivariate analyses were done to explore the association between the dependent and independent variables. Binary logistic regression models were then executed. A 2-tailed p-value < 0.05 was considered significant.

Results

EBF rate was nearly 60%. Cessation of EBF was associated with younger age, inconvenience/fatigue due to BF, sore breasts or nipples/too painful, perceived low milk quantity, BF skills were not effective, maternal choice, and baby-centred factors.

Conclusion and Recommendations

EBF was associated with problems/difficulties in BF technique. It is recommended that health care professionals like doctors, nurses, and midwives should train mothers during and after pregnancy regarding BF technique or pumping breast milk in case of BF difficulties, improve mothers’ confidence about the ability to breastfeed and enhance mothers’ knowledge on the normal process of lactation. Secondly, it is the role of policymakers to ensure implementation of Baby-Friendly Hospital Initiative (BFHI) guidelines in hospitals to meet the WHO’s global target of infants being exclusively breastfed until six months of age.

New perspectives on the topical management of recurrent candidiasis

Candidiasis is a common opportunistic infection caused by fungi of the Candida genus that affects mainly mucocutaneous tissues (e.g., vaginal, oral, and mammary). This condition has been known for a long time; thus, innumerous topical and systemic treatments are already available on the market worldwide. Yet, recurrent superficial candidiasis (RSC) is an expected outcome, still lacking effective and convenient treatments. Although several individual conditions may contribute to disease recurrence, biofilms' presence seems to be the main etiological factor contributing to antifungal resistance. More than proposing novel antifungal agents, current research seems to be focusing on improving the pharmaceutical technology aspects of formulations to address such a challenge. These include extending and improving intimate contact of drug delivery systems with the mucocutaneous tissues, increasing drug loading dose, and enhancing topical drug permeation. This review discusses the current understanding of the RSC and the use of pharmaceutical technology tools in obtaining better results. Even though several drawbacks of conventional formulations have been circumvented with the help of nano- or microencapsulation techniques and with the use of mucoadhesive formulation excipients, many challenges remain. In particular, the need to mask the unpalatable taste of formulations for the treatment of oral candidiasis, and the necessity of formulations with a "dryer" sensorial feeling and improved performances in providing higher bioavailability for the treatment of mammary and vaginal candidiasis.

Description of an mHealth tool for breastfeeding support: LactApp. Analysis of how lactating mothers seek support at critical breastfeeding points and according to their infant's age

Interventions in mHealth have had positive effects on establishing and maintaining breastfeeding, but we still do not know what content women consult when downloading a breastfeeding mobile application. We conducted an observational, descriptive, and retrospective study using the data recorded by LactApp in 2019. The most frequently consulted topics were those related to breastfeeding technique, infant sleep, human milk management and storage, breastfeeding myths, breastfeeding stages, complementary feeding, infant care, and returning to work. Our study results suggest that LactApp's support seems to develop with mothers' needs according to their infant's development stage. The first breastfeeding days include more physiological answers. Between 15 days and 3 months, mothers look for support in topics like breastfeeding crisis/complications and returning to work. At 3 months to 1 year, answers are related to complementary feeding and weaning. When the user's infant is 1 year of age, mothers seek support for weaning, weaning management, and tandem breastfeeding.

OXTR rs53576 Variation with Breast and Nipple Pain in Breastfeeding Women

BACKGROUND

Thirty percent of women who seek professional breastfeeding support require assistance with ongoing breast and nipple pain and < 50% of women report resolution of their pain. It is unknown if there is a molecular risk for ongoing breast and nipple pain during breastfeeding. Aim -To evaluate associations among breast and nipple pain sensitivity and candidate pain sensitivity single-nucleotide polymorphisms [SNPs], (COMT rs6269, rs4633, rs4818, rs4680 and OXTR rs2254298, rs53576) in breastfeeding women. Design - A secondary analysis of a pilot randomized controlled trial of a pain self-management intervention conducted over 6 weeks postpartum. Setting and Participants - Sixty women were recruited from two hospital settings after birth. Methods - All participants underwent standardized mechanical somatosensory testing for an assessment of pain sensitivity and provided baseline buccal swabs for genetic analysis. At 1, 2, and 6 weeks postpartum, women self-reported breast and nipple pain severity using a visual analogue scale. Results - Women with the minor allele OXTR rs53576 reported 8.18-fold higher breast and nipple pain severity over time. For every 1-unit increase in Mechanical detection threshold and windup ratio, women reported 16.51-fold and 4.82-fold higher breast and nipple pain severity respectively. Six women with the OXTR rs2254298 minor allele reported allodynia. Conclusion - The presence of OXTR alleles in women with enhanced pain sensitivity suggests a phenotype of genetic risk for ongoing breast and nipple with potential for pain-associated breastfeeding cessation. Somatosensory testing identified women who reported higher breast and nipple pain during the first weeks of breastfeeding.

Symptoms of problematic feeding in infants under 1 year of age undergoing frenotomy: A review article

AIM

The aims of this systematic review were to first identify and summarise original research that compared symptoms of problematic feeding in infants with tongue tie before and after frenotomy and then evaluate the quality of measures used to assess problematic feeding.

METHODS

CINAHL and PubMed were searched for ((tongue-tie) or (ankyloglossia)) and ((feeding) or (breastfeeding) or (bottle-feeding)) and ((frenotomy) or (frenectomy) or (frenulectomy) or (frenulotomy)). Original research reporting on feeding before and after frenotomy in infants under 1 year old was included.

RESULTS

Maternal nipple pain, breastfeeding self-efficacy and LATCH scores improved after frenotomy. Few data are available on the effect of frenotomy on infant feeding. The measures used to assess infant feeding were not comprehensive and did not possess strong psychometric properties.

CONCLUSION

Literature suggests that maternal nipple pain, self-efficacy and LATCH scores improve in breastfeeding mother-infant dyads after frenotomy. However, current literature does not provide adequate data regarding the effect of frenotomy on the infant's ability to feed or which infants benefit from the procedure. Future research should utilise comprehensive, psychometrically sound measures to assess infants for tongue tie and to evaluate infant feeding to provide stronger evidence for the effect of frenotomy on feeding in infants with tongue tie.

Effect of nipple shield use on milk removal: a mechanistic study

BACKGROUND

Concerns about reduced milk transfer with nipple shield (NS) use are based on evidence from studies with methodological flaws. Milk removal during breastfeeding can be impacted by infant and maternal factors other than NS use. The aim of this study was to control electric breast pump vacuum strength, pattern and duration across multiple study sessions to determine if NS use reduces milk removal from the breast.

METHODS

A within-subject study with two groups of breastfeeding mothers (infants < 6 months) were recruited; Control Group (CG): no breastfeeding difficulties; Pain Group (PG) used NS for persistent nipple pain. Mothers completed three randomised 15 min pumping sessions using the Symphony vacuum curve (Medela AG); no NS, fitted NS, and a small NS. Sessions were considered valid where the applied vacuum was within 20 mmHg of the set vacuum. Milk removal was considered as pumped milk volume, and also percentage of available milk removed (PAMR), which is calculated as the pumped volume divided by the estimated milk volume stored in the breast immediately prior to pumping.

RESULTS

Of 62 sessions (all: n = 31 paired sessions) a total of 11 paired sessions from both PG (n = 03) and CG (n = 08) were valid (subset) with and without a fitted NS. Only 2 small shield sessions were valid and so all small shield measurements were excluded. Both pumped volumes and PAMR were significantly lower with NS use for all data but not for subset data. (All: Volume and PAMR median: no NS: 76.5 mL, 69%, Fitted NS: 32.1 mL, 41% respectively (volume p = 0.002, PAMR p = 0.002); Subset: Volume and PAMR median: no NS: 83.8 mL, 72%; Fitted NS: 35.2 mL, 40% (volume p = 0.111 and PAMR p = 0.045). The difference in PAMR, but not volume, was statistically significant when analysed by linear mixed modelling. A decrease of 10 mmHg was associated with a 4.4% increase in PAMR (p = 0.017).

CONCLUSIONS

This experimental data suggests that nipple shield use may reduce milk removal. Close clinical monitoring of breastfeeding mothers using nipple shields is warranted.

Predictors of exclusive breastfeeding practice among migrant and non-migrant mothers in urban China: results from a cross-sectional survey

OBJECTIVE

To explore and compare the predictors for exclusive breast feeding (EBF) among migrant and non-migrant mothers in China.

DESIGN

A large-scale cross-sectional study.

SETTING

12 counties/districts were covered in China.

PARTICIPANTS

A total number of 10 408 mothers were recruited, of whom 3571 mothers of infants aged 0-5 months in urban China were used for analysis.

OUTCOME

The practice of EBF was calculated based on the foods and drinks consumed in the last 24 hours, as recommended by WHO.

RESULTS

Around 30% of Chinese mothers with infants aged 0-5 months practised EBF in urban areas, with no significant difference between migrant and non-migrant mothers (p=0.433). Among the migrant mothers, factors associated with EBF included residence in big cities (adjusted OR, AOR 1.68 (95% CI 1.20 to 2.34)), premature birth (AOR 0.27 (95% CI 0.09 to 0.81)), knowledge about EBF (AOR 2.00 (95% CI 1.51 to 2.65)), low intention of breast feeding in the first month postpartum (AOR 0.59 (95% CI 0.36 to 0.97)) and mothers working in agriculture-related fields or as casual workers (AOR 1.77 (95% CI 1.18 to 2.64)). Among non-migrant mothers, in addition to similar predictors including residence in big cities (AOR 1.40 (95% CI 1.13 to 1.73)), knowledge about EBF (AOR 1.25 (95% CI 1.02 to 1.53)) and low intention of breast feeding in the first month post partum (AOR 0.46 (95% CI 0.31 to 0.70)], early initiation of breast feeding (EIBF) (AOR 1.78 (95% CI 1.35 to 2.33)) and caesarean delivery (AOR 0.74 (95% CI 0.60 to 0.89)) were also factors associated with EBF.

CONCLUSIONS

There was no significant difference in the prevalence of EBF between migrant and non-migrant mothers in urban China. Premature birth and maternal occupation in agriculture-related fields or casual work were distinctive factors associated with EBF for migrants, while EIBF and caesarean delivery were unique predictors for non-migrants.

Exclusive breastfeeding practice and associated factors among first-time mothers in Bahir Dar city, North West Ethiopia, removed: A community based cross sectional study

Background

Breastfeeding can offer the ideal food for infants. It contains all the necessary nutrients for the growthand development of infants and antibodies that can protect from many childhood illnesses. Understanding the extent of, and barriers to exclusive breastfeeding in Ethiopia is important for learning how to best improve level of exclusive breastfeeding. No single study has been conducted on first-time mothers in the country. . Therefore, this study aimed to assess prevalence of exclusive breastfeeding practice and associated factors among first-time mothers in Bahir Dar city, North West Ethiopia.

Method

A community-based cross-sectional study was conducted from March to April, 2016 among (n = 400) randomly selected first-time mothers in Bahir Dar city, northwest Ethiopia. Data were collected using structured interviewer-administered questionnaire and analyzed using SPSS version20., bivariate and multivariate logistic regression analyses were carried out. Odds ratio with 95% confidence interval was used to measure the strength of association. Statistical significance was declared at P -value <0.05.

Results

Prevalence of exclusive breastfeeding practice 24 h before the survey was 57.3% (95%CI: 52.3%–62%). Mothers not being married (aOR = 2.79, 95 %CI: 1.08, 7.17), supported by their husband (aOR = 4.15, 95%CI: 2.13, 6.28), with no breast complication (aOR = 3.66, 95% CI: 2.13, 6.28), who had four or more antenatal care (aOR = 2.51, 95%CI: 1.49, 4.23) were more likely to practice exclusive breastfeeding.

Conclusion

A significant proportion of mothers had a low level of exclusive breastfeeding practice that was lower than the national recommended level. Mothers not being married, supported by their husbands, with no breast problems who had four or more antenatal care visits were more likely to practice exclusive breastfeeding. These results suggest that multi-sectorial and multi-disciplinary approaches are needed to increase exclusive breastfeeding in the first-time mothers.

Breastfeeding technique and the incidence of nipple traumas in puerperal women attended in a city hospital: intervention study

Abstract Objectives: to evaluate the effect of an intervention on the incidence of nipple trauma and the quality of breastfeeding technique in the first month of postpartum. Methods: this is a quasi-randomized intervention study with 180 puerperal women equally distributed between experimental and control groups. The intervention was performed at a maternity and consisted of an educational session on breastfeeding technique. A descrip-tive analysis of the groups’ characteristics was performed, comparing the frequencies of unfa-vorable parameters related to breastfeeding technique between groups. Pearson’s chi-square test and Fisher’s test were used, and p≤0.05 was adopted as the critical level of significance. Results: at 30 days, 64% and 15% of the mothers used the technique correctly, respec-tively, in the experimental and control groups with RR=4.87 (CI95%=2.93-8.34); NNT=1.96 (CI95% =1.61-2.72); p<0.001. In the experimental group, a decrease was observed in the unfavorable parameters of the breastfeeding technique (p≤0.05). The incidence of nipple trauma was 30% in the experimental group and 38.9% in the control group (p=0.21). Conclusions: the intervention was insufficient to prevent nipple trauma in the experi-mental group, but significantly improved the quality in the breastfeeding technique.

The Patterns and Social Determinants of Breastfeeding in 12 Selected Regions in China: A Population-Based Cross-Sectional Study

BACKGROUND

With rapid industrialization and urbanization, there is a growing need for women to enter the workforce, and affluent people are drawn to the infant formula market. The breastfeeding rates in China are below the optimal level. Large scale quantitative research studying breastfeeding practices after 2015 in China are lacking.

RESEARCH AIM

We aimed to (1) explore the latest patterns and (2) identify the determinants of breastfeeding in China.

METHODS

The study was a population-based, cross-sectional survey. A multi-stage sampling technique was adopted for the selection of participants. We recruited 10,408 mothers with children under 12 months old, in 12 regions of China, and conducted a questionnaire survey about breastfeeding patterns. The associations between social and biophysical determinants and breastfeeding outcomes were analyzed using a logistic regression model.

RESULTS

The exclusive breastfeeding rate was 29.32% (n = 3,052) decreasing from 32.71% (n = 3,404) to 15.83% (n = 1,648) among children aged 0-5 months. Cesarean section had a negative association with early breastfeeding initiation (OR = .33, 95% CI [.30, .36]), exclusive breastfeeding (OR = .78, 95% CI [.69, .89]), and predominant breastfeeding (OR = .73, 95% CI [.65, .83]). Compared to participants with an annual household income lower than 40,000 Yuan ($5,817 USD), those with over 100,000 Yuan ($14,542 USD) had an OR of .78 (95% CI [.67, .90]) in exclusive breastfeeding. Compared with illiterate and unemployed groups, middle/high school education and a current work status, respectively, were associated with a lower likelihood of exclusive breastfeeding (OR = .73, 95% CI [.63, .84]; OR = .58, 95% CI [.37, .89]).

CONCLUSIONS

The prevalence of breastfeeding in 12 selected regions in China was low and interventions focusing on the targeted population should be strengthened.

Latch-related nipple pain in breastfeeding women: the impact on breastfeeding outcomes

Background

Nipple pain is a common issue experienced by breastfeeding mothers and if not resolved, can contribute to early cessation of breastfeeding.

Aims

To investigate mothers experiences of nipple pain, the solutions used to manage their issues, and the perceived impact on breastfeeding outcomes with particular focus on latch-related nipple pain with no clear underlying cause (LRNP).

Methods

Data was collected via an online survey of UK-based women (n=1084).

Findings

LRNP was the most common issue as experienced by 52% of mothers surveyed. Various solutions were utilised to try to manage LRNP. Use of Highly Purified Anhydrous (HPA) Lanolin to manage LRNP was associated with a substantial increase in breastfeeding duration (average 33.2 weeks compared to 26.5 weeks for those who didn't report using HPA Lanolin).

Discussion

HPA Lanolin is a key solution used by mothers in the management of latch-related nipple pain and one which they perceive as having a significant positive effect on the physical symptoms and pain associated with nipple trauma. Use of HPA Lanolin was also associated with a substantial increase in breastfeeding duration which ultimately aids women in meeting their personal breastfeeding goals and improves overall breastfeeding rates.

Main Barriers to Optimal Breastfeeding Practices in Armenia: A Qualitative Study

BACKGROUND

In 2015, the median duration of exclusive breastfeeding was 2.2 months in Armenia, and only 15% of 4-5-month-old children were exclusively breastfed, indicating an issue with breastfeeding knowledge and practices.

RESEARCH AIM

To identify the main barriers to optimal breastfeeding practices in Armenia.

METHODS

We used qualitative research methods via focus group discussions and in-depth interviews with four groups of providers from different levels of care, and mothers of young children, from Yerevan city and two provinces, Lori and Shirak. Overall, eight in-depth interviews and 13 focus group discussions were conducted with a total of 99 participants. Qualitative content analysis was applied, with elements of both inductive and deductive approaches.

RESULTS

We identified two main categories of barriers to optimal breastfeeding-systemic barriers and knowledge deficiencies. The main themes within systemic barriers were lack of skilled breastfeeding support services and low motivation of providers-mainly related to inadequate recognition of their role in breastfeeding counseling and low remuneration. The main knowledge-related barriers were insufficient counseling of mothers, lack of reliable information sources about infant feeding, and misconceptions among both mothers and providers.

CONCLUSION

Optimal breastfeeding is crucial for the best start to an infant's life; however, there were a number of barriers to optimal breastfeeding practices in Armenia. Our findings and recommendations could help policymakers apply effective strategies for improving breastfeeding rates in Armenia. Considering the similar historical backgrounds of the post-Soviet countries, our findings could also be applicable to other Commonwealth of Independent States countries.

Clinical Consensus Statement: Ankyloglossia in Children

OBJECTIVE

To identify and seek consensus on issues and controversies related to ankyloglossia and upper lip tie in children by using established methodology for American Academy of Otolaryngology-Head and Neck Surgery clinical consensus statements.

METHODS

An expert panel of pediatric otolaryngologists was assembled with nominated representatives of otolaryngology organizations. The target population was children aged 0 to 18 years, including breastfeeding infants. A modified Delphi method was used to distill expert opinion into clinical statements that met a standardized definition of consensus, per established methodology published by the American Academy of Otolaryngology-Head and Neck Surgery.

RESULTS

After 3 iterative Delphi method surveys of 89 total statements, 41 met the predefined criteria for consensus, 17 were near consensus, and 28 did not reach consensus. The clinical statements were grouped into several categories for the purposes of presentation and discussion: ankyloglossia (general), buccal tie, ankyloglossia and sleep apnea, ankyloglossia and breastfeeding, frenotomy indications and informed consent, frenotomy procedure, ankyloglossia in older children, and maxillary labial frenulum.

CONCLUSION

This expert panel reached consensus on several statements that clarify the diagnosis, management, and treatment of ankyloglossia in children 0 to 18 years of age. Lack of consensus on other statements likely reflects knowledge gaps and lack of evidence regarding the diagnosis, management, and treatment of ankyloglossia. Expert panel consensus may provide helpful information for otolaryngologists treating patients with ankyloglossia.

Evidence-Based Updates on the First Week of Exclusive Breastfeeding Among Infants ≥35 Weeks

The nutritional and immunologic properties of human milk, along with clear evidence of dose-dependent optimal health outcomes for both mothers and infants, provide a compelling rationale to support exclusive breastfeeding. US women increasingly intend to breastfeed exclusively for 6 months. Because establishing lactation can be challenging, exclusivity is often compromised in hopes of preventing feeding-related neonatal complications, potentially affecting the continuation and duration of breastfeeding. Risk factors for impaired lactogenesis are identifiable and common. Clinicians must be able to recognize normative patterns of exclusive breastfeeding in the first week while proactively identifying potential challenges. In this review, we provide new evidence from the past 10 years on the following topics relevant to exclusive breastfeeding: milk production and transfer, neonatal weight and output assessment, management of glucose and bilirubin, immune development and the microbiome, supplementation, and health system factors. We focus on the early days of exclusive breastfeeding in healthy newborns ≥35 weeks' gestation managed in the routine postpartum unit. With this evidence-based clinical review, we provide detailed guidance in identifying medical indications for early supplementation and can inform best practices for both birthing facilities and providers.

Surface Electromyographic Analysis of the Suprahyoid Muscles in Infants Based on Lingual Frenulum Attachment during Breastfeeding

Muscle electrical activity analysis can aid in the identification of oral motor dysfunctions, such as those resulting from an altered lingual frenulum, which consequently impairs feeding. Here, we aim to analyze the suprahyoid muscle electrical activity of infants via surface electromyography, based on lingual frenulum attachment to the sublingual aspect of the tongue and floor of the mouth during breastfeeding. In the present study, we have studied full-term infants of both genders, aged between 1 and 4 months old. The mean muscle activities were recorded in microvolts and converted into percent values of the reference value. Associations between the root mean square and independent variables were tested by one-way analysis of variance and Student’s t-test, with a significance level of 5% and test power of 95%, respectively. We evaluated 235 infants. Lower mean muscle electrical activity was observed with the lingual frenulum attached to apex/lower alveolar ridge, followed by attachment to the middle third/lower alveolar ridge, and between the middle third and apex/lower alveolar ridge. Greater suprahyoid muscle activity was observed with lingual frenulum attachment to the middle third of the tongue/sublingual caruncles, showing a coordination between swallowing, sucking, and breathing. Surface electromyography is effective in diagnosing lingual frenulum alterations, the attachment points of which raises doubt concerning the restriction of tongue mobility. Thus, it is possible to identify oral motor dysfunctions.
