Mode of birth and clinical factors associated with exclusive breastfeeding at hospital discharge: a retrospective cross-sectional study of women and full-term infants in Greece

World Health Organization recommends exclusive breastfeeding for six months. Despite its well- documented benefits, breastfeeding rates worldwide do not meet the recommended goals. The aim of this study was to identify factors that could influence exclusive breastfeeding at hospital discharge. All live, singleton, term births in a private hospital of Athens, Greece between January and December 2019 were included with a final study sample of 7336 women and newborns. Our study identifies several factors associated with nonexclusive breastfeeding ta hospital discharge: nullipara women compared to multipara (OR 0.73; 95% CI 0.66, 0.82), cesarean delivery compared to vaginal delivery (OR 1.83; 95% CI 1.65, 2.03), smoking during pregnancy (OR 1.28; 95% CI 1.15, 1.44), gestational age at 37+0- 38+6 weeks compared to 39+0- 41+6 weeks (OR 0.70; 95% CI 0.62, 0.78), birthweight <2500g (OR 0.38; 95% CI 0.22, 0.35), and admission to neonatal intensive unit (NICU) after delivery (OR 8.19; 95% CI 6.65, 10.08). No association was observed for maternal age, pregnancy after assisted reproductive technology, gestational diabetes, obstetric complication, and sex of the newborn. It is expected that our results will allow future comparisons between different hospitals in the same country, as well as comparison of practices with other countries. Several perinatal factors related to nonexclusive breastfeeding at hospital discharge, most noteworthy were caesarean section and admission to NICU.

Association between decision-to-delivery time and neonatal outcomes: a systematic review and meta-analysis

BackgroundDecision-to-delivery time (DDT), a crucial factor during the emergency caesarean section, may potentially impact neonatal outcomes. This study aims to assess the association between DDT and various neonatal outcomes.MethodsA comprehensive search of PubMed, Scopus, Cochrane Library, and Google Scholar databases was conducted. A total of 32 eligible studies that reported on various neonatal outcomes, such as Apgar score, acidosis, neonatal intensive unit (NICU) admissions and mortality were included in the review. Studies were selected based on predefined eligibility criteria, and a random-effects inverse-variance model with DerSimonian-Laird estimate of tau² was used for meta-analysis. Heterogeneity and publication bias were assessed using I² statistics and Egger’s test, respectively.ResultsThe meta-analysis revealed a significant association between DDT < 30 min and increased risk of Apgar score < 7 (OR 1.803, 95% CI: 1.284–2.533) and umbilical cord pH < 7.1 (OR 4.322, 95% CI: 2.302–8.115), with substantial heterogeneity. No significant association was found between DDT and NICU admission (OR 0.982, 95% CI: 0.767–1.258) or neonatal mortality (OR 0.983, 95% CI: 0.565–1.708), with negligible heterogeneity. Publication bias was not detected for any outcomes.ConclusionsThis study underscores the association between shorter DDT and increased odds of adverse neonatal outcomes such as low Apgar scores and acidosis, while no significant association was found in terms of NICU admissions or neonatal mortality. Our findings highlight the complexity of DDT’s impact, suggesting the need for nuanced clinical decision-making in cases of emergency caesarean sections.

Impact of bariatric surgery on maternal gestational weight gain and pregnancy outcomes in women with obesity: A population-based cohort study from Qatar.

Bariatric surgery is performed in obese women of reproductive age to help achieve a healthy prepregnancy weight to reduce the complications associated with obesity in pregnancy. However, these procedures can impact maternal nutrition and gestational weight gain (GWG). This study evaluates the maternal and neonatal outcomes in women with prepregnancy bariatric surgery and determines the impact on GWG. This study included 24 weeks gestation or more pregnancies, with a maternal BMI at delivery of 30 kg/m2 or more. It was categorized into two groups based on whether they had prepregnancy bariatric surgery (exposed) or not (unexposed). The outcomes included gestational diabetes (GDM), gestational hypertension (GHT), mode of delivery, preterm birth (PTB), GWG, birthweight (BW) and customized BW centiles, low birthweight (LBW), congenital anomalies, and admission to the neonatal intensive unit (NICU). Categorization was also done based on the adequacy of GWG (low, adequate, and excess). A total of 8,323 women were included in the study, 194 of whom had prepregnancy bariatric surgery. After adjusting for confounders, the exposed group had a mean GWG 1.33 kg higher than the unexposed group (95% CI 0.55-2.13, p=0.001). The exposed group had higher odds of PTB (aOR 1.78, 95% CI 1.16-2.74, p=0.008), CD (aOR 6.52, 95% CI 4.28-9.93, p<0.001), LBW in term babies (aOR 2.60, 95% CI 1.34-5.03, p=0.005), congenital anomalies (aOR 2.64, 95% CI 1.21-5.77, p=0.015), low APGAR score (aOR 3.75, 95% CI 1.12-12.5, p=0.032) and 80.4g lesser birthweight (95% CI -153.0, -5.8; p=0.034). More women in the low GWG category had LBW babies (28.6% versus 6.7% in the high GWG group, p=0.033), lowest mean BW and median BW centiles (2775 grams versus 3289 grams in the high GWG group, p=0.004 and 57.5% versus 74.5% in the high GWG group, p=0.040, respectively). The findings of this study highlight differences in perinatal outcomes such as preterm birth, low birth weight, congenital anomalies, cesarean deliveries, and gestational weight gain between post-bariatric women and controls. These insights can help inform the planning and provision of appropriate maternity care to enhance patient safety and outcomes. The results of this study can also guide the counseling of reproductive age-group women who are planning to undergo bariatric surgery.

Parental satisfaction with neonatal intensive care unit services and associated factors in Ethiopia: systematic review and meta-analysis

BackgroundIn the context of healthcare, satisfaction is the attainment of adequate or acceptable treatment and serves as both a benchmark for quality and the ultimate objective of providing care. In neonatal care facilities, parent satisfaction is a key measure of the quality of the services offered to the newborns and aids in improving healthcare delivery. This is the first systematic review aiming to address critical knowledge gaps regarding factors influencing parental satisfaction with neonatal intensive care unit services, and determine pooled prevalence in Ethiopia.MethodsAfter comprehensive systematic search for full texts in the English language through an electronic web-based search strategy from databases of PubMed, CINAHL, Embase, African Journals Online, PsycINFO, and Google Scholar, included a total of 8 articles. Checklists from the Joanna Briggs Institute were used to assess the studies’ quality of methodology. STATA version 14 software for windows was used for all statistical analyses and meta-analysis was done using a random-effects method. Subgroup and sensitivity analyses were performed to clarify the source of heterogeneity.ResultsPooled national level of parents’ satisfaction with neonatal intensive unit service was 57.87% (95% CI (49.99, 65.75%)). Age of respondents and availability of chair were significantly associated with parents’ satisfaction with neonatal intensive unit service.Conclusions and recommendationIn our review we found that nearly half of parents expressed dissatisfaction with neonatal intensive unit service, which is high. Age of respondents and availability of chair in neonatal intensive unit waiting area were significantly associated with neonatal intensive unit service. Efforts to enhance parental satisfaction with neonatal intensive unit services are crucial, given that nearly half of parents reported dissatisfaction. Necessary infrastructure should be fulfilled to increase parental satisfaction with neonatal intensive unit service.(PROSPERO) International prospective register of systematic reviews:CRD42023483474

Thai novice nurses’ lived experiences and perspectives of breastfeeding and human milk in the Neonatal Intensive Care Unit (NICU)

BackgroundBreastfeeding and human milk have well-documented health benefits for newborn infants, particularly those who are sick. However, breastfeeding rates and human milk feeding among infants in neonatal intensive units (NICU) in Thailand are still low; thus, breastfeeding promotion and support are required for Thai mothers of premature infants. Newly graduated nurses can play a critical role within the healthcare support system and can have a significant impact on improving breastfeeding practices in the NICU. The objective of this study was to investigate the lived experiences and perspectives of Thai novice nurses on supporting breastfeeding and human milk feeding in the NICU.MethodsThe study was conducted between March 2021 and May 2022 at three medical centers in the central region of Thailand. This study employed a descriptive phenomenological approach to explore Thai novice nurses’ experiences and perspectives on breastfeeding. Purposive sampling was used to invite Thai novice nurses who have work experience in providing breastfeeding support to NICU mothers and their infants to participate in online interviews using a video conference platform (Zoom). Semi-structured questions were used to interview study participants in their native language. Data were analyzed using Colaizzi’s method of data analysis to identify emergent themes. Member checks, peer debriefing, and self-reflection were applied to ensure the validity and trustworthiness of the study results. Back-translation was also used as a quality and accuracy assurance.ResultsA total of thirteen novice nurses agreed to participate in the study. All were female, and their ages ranged from 21 to 24 years old at the time of the interview. The researchers identified five major themes related to the overall study objectives and research questions. They are: positive attitude toward breastfeeding and human milk, facing breastfeeding challenges at work, self-confidence rooted in experience, professional skill needs, and requiring further support.ConclusionsOur results suggest that breastfeeding education plays a vital role in encouraging new nurses to provide breastfeeding support to mothers of preterm infants. Establishing breastfeeding support training and innovative learning strategies can be crucial in developing appropriate breastfeeding practice guidelines and policies to support Thai breastfeeding mothers in the NICU.

Heart Rate Variability as a Prognostic Tool for Gastroschisis Infants in the Neonatal Intensive Critical Unit.

Gastroschisis is the most common congenital abdominal wall defect, with an increasing incidence. It results in extrusion of abdominal contents with associated delayed intestinal motility. Abnormal heart rate characteristics (HRCs) such as decreased variability occur due to the inflammatory response to sepsis in preterm infants. This study aimed to test the hypothesis that infants with gastroschisis have decreased heart rate variability (HRV) after birth and that this physiomarker may predict outcomes. We analyzed heart rate data from and clinical variables for all infants admitted with gastroschisis from 2009 to 2020. Forty-seven infants were admitted during the study period and had available data. Complex gastroschisis infants had reduced HRV after birth. For those with sepsis and necrotizing enterocolitis, abnormal HRCs occurred early in the course of illness. Decreased HRV was associated with complex gastroschisis. Infants in this group experienced complications that prolonged time to full enteral feeding and time on total parenteral nutrition. · Infants with gastroschisis can be classified into two subcategories, simple and complex disease.. · Those with complex disease often require prolonged stays in the neonatal intensive care unit and costly hospitalizations. We hypothesized that infants with complex gastroschisis are more likely to have abnormal HRC due to intestinal inflammation.. · In this study, we identified associations between abnormal HRV, heart rate characteristicHRC, and the development of gastroschisis complications. Additionally, we described differences in clinical characteristics between infants with complex versus simple gastroschisis..

Epidemiology of neonatal sepsis in two neonatal intensive care units in Krakow, Poland in 2016–2017 years

BackgroundSepsis in low-birth-weight neonates remains one of the most significant causes of neonatal morbidity and mortality. Approximately 3 million newborns suffer from sepsis globally every year. The aim of this study was to compare demographic and clinical features, as well as etiology and antibiotic susceptibility, of the main pathogens related to neonatal sepsis in two neonatal intensive units during a two-year period.MethodsWe observed early-onset (EO-BSI) and late-onset bloodstream infections (LO-BSI) cases in two high-reference neonatal intensive care units (NICU) over a 24-month period (2016–2017). Samples of patients’ blood were tested for the presence of the microorganisms. All bacterial isolates were tested for susceptibility to antibiotics.ResultsThe majority of sepsis cases weighed above 1000 g and were born by cesarean section. About 10% of the EO-BSI group died. There were differences in the EO-BSI /LO-BSI ratio in the compared wards due to differences among the admitted children. The most common pathogens isolated from blood were coagulase-negative staphylococci (CoNS) were represented by two dominating species: S. epidermidis and S. haemolyticus, followed by Klebsiella spp. strains and E.coli, which were mostly found in EO-BSI cases. No single S. agalactiae (GBS) strain was isolated. The majority of CoNS strains were resistant to methicillin, half were resistant to aminoglycosides, and one-third were resistant to macrolides and lincosamides. Half of the Gram-negative rods were resistant to beta-lactams.ConclusionsThe epidemiology of sepsis in two observed NICUs is comparable to data obtained from other studies with a predominance of methicillin-resistant CoNS in LO-BSI and beta-lactam resistant E. coli in EO-BSI. It is of importance that the campaign for controlling GBS carriage in pregnant women in Poland resulted in the disappearance of GBS as a cause of sepsis. Unfortunately, there are no such measures to control E.coli related sepsis.

Therapeutic Plasma Exchange in Early-Onset Preeclampsia: A 7-Year Monocentric Experience.

Different therapeutic apheresis techniques have been clinically tested to delay preterm delivery in the case of eoPE (early-onset preeclampsia). Our study evaluated the feasibility of TPE (therapeutic plasma exchange) compared to standard-of-care treatment. Twenty patients treated with 95 TPE sessions were included in the final analysis and retrospectively matched with 21 patients with comparable placental dysfunction. Gestational age at admission was 23.75 ± 2.26 versus 27.57 ± 2.68 weeks of gestation (WoG) in the control group (p = < 0.001), mean sFlt-1/PlGF ratio was 1946.26 ± 2301.63 versus 2146.70 ± 3273.63 (p = 0.821) and mean sEng was 87.63 ± 108.2 ng/mL versus 114.48 ± 88.78 ng/mL (p = 0.445). Pregnancy was prolonged for 8.25 ± 5.97 days when TPE was started, compared to 3.14 ± 4.57 days (p = 0.004). The median sFlt-1/PlGF Ratio was 1430 before and 1153 after TPE (-18.02%). Median sEng fell from 55.96 ng/mL to 47.62 mg/mL (-27.73%). The fetal survival rate was higher in TPE-treated cases. NICU (Neonatal Intensive Center Unit) stay was in the median of 63 days in the TPE group versus 48 days in the standard-of-care group (p = 0.248). To date, this monocentric retrospective study, reports the largest experience with extracorporeal treatments in eoPE worldwide. TPE could improve pregnancy duration and reduce sFlt-1 and sEng in maternal serum without impairing neonatal outcomes.

Optical Coherence Tomography and Optical Coherence Tomography Angiography in Pediatric Retinal Diseases

Indirect ophthalmoscopy and handheld retinal imaging are the most common and traditional modalities for the evaluation and documentation of the pediatric fundus, especially for pre-verbal children. Optical coherence tomography (OCT) allows for in vivo visualization that resembles histology, and optical coherence tomography angiography (OCTA) allows for non-invasive depth-resolved imaging of the retinal vasculature. Both OCT and OCTA were extensively used and studied in adults, but not in children. The advent of prototype handheld OCT and OCTA have allowed for detailed imaging in younger infants and even neonates in the neonatal care intensive unit with retinopathy of prematurity (ROP). In this review, we discuss the use of OCTA and OCTA in various pediatric retinal diseases, including ROP, familial exudative vitreoretinopathy (FEVR), Coats disease and other less common diseases. For example, handheld portable OCT was shown to detect subclinical macular edema and incomplete foveal development in ROP, as well as subretinal exudation and fibrosis in Coats disease. Some challenges in the pediatric age group include the lack of a normative database and the difficulty in image registration for longitudinal comparison. We believe that technological improvements in the use of OCT and OCTA will improve our understanding and care of pediatric retina patients in the future.

Evaluation of fetal thymus size in maternal autoimmune diseases: systemic lupus erythematosus, Sjögren's syndrome and antiphospholipid antibody syndrome.

To investigate the effect of inflammation on the fetal thymus-thoracic ratio (TTR) in pregnant women with systemic lupus erythematosus (SLE), Sjögren's syndrome (SS) and antiphospholipid antibody syndrome (APS). This prospective case-control study included 45 pregnant women with SLE, SS, and APS and 90 gestational age-matched healthy pregnant women between 24 and 37 gestational weeks. The ratio of the anteroposterior fetal thymus length to the transverse mediastinal length was calculated as the TTR in the study groups. Fetal TTR was significantly lower in the case group (p < 0.001). Fetal TTR in the APS group was significantly lower than SS group (p = 006). The patients using hydroxychloroquine (HCQ) had significantly higher fetal TTR compared to patients not using HCQ (p = 0.004). A moderate negative correlation was found between the disease duration and fetal TTR (r = - 0.552, p < 0.001). In predicting admission to the neonatal intensive unit care (NICU), a value of 0.31 was found for the fetal TTR with a sensitivity of 83.3% and a specificity of 69% CONCLUSION: Maternal inflammation in pregnancies with autoimmune diseases may affect the intrauterine milieu of the fetus and cause a lower fetal TTR. Additionally, the lower level of fetal TTR may be more effective and beneficial for the clinician if combined with other risk factors in predicting NICU admission.

Second successful pregnancy following liver transplantation

Liver transplantation for end stage liver disease, offers the recipient a near normal life, including pregnancies for women. Successful pregnancies have been reported, but successful second pregnancies are rare. We present our patient with a second successful pregnancy following her liver transplantation. A 22-year-old living donor liver transplant (LT) recipient was enrolled in our unit for antenatal care of her second pregnancy. Her native liver had failed due to autoimmune hepatitis. She had her first planned pregnancy at 19 months post-transplant. The second pregnancy was a spontaneous conception a year later. The obstetric parameters were normal, but she developed signs of suspected graft rejection and hence an emergency cesarean section was done. A preterm baby was delivered with a good APGAR score. The baby was treated in neonatal intensive unit for four days. The mother recovered well and the liver parameters normalized on the sixth postoperative day. Liver transplantation restores fertility in transplant recipients. Pregnancy, the liver graft and the associated medications have a complex interplay. Post LT pregnancy outcome can be optimized with a multidisciplinary approach. Better understanding and close monitoring is essential for a successful outcome.

Colistin Resistance in Gram Negative Bacteria in a Tertiary Care Neonatal Intensive Unit in Odisha

Colistin Resistance in Gram Negative Bacteria in a Tertiary Care Neonatal Intensive Unit in Odisha

Analysis of Knowledge, Attitudes and Behaviours of Health Care Workers towards Vaccine-Preventable Diseases and Recommended Vaccinations: An Observational Study in a Teaching Hospital.

Background: Recommended vaccinations are the cheapest and most effective measure to reduce the risk of transmission and related complications, especially in high-risk healthcare settings. This study aimed to evaluate the knowledge, attitudes and behaviours of HCWs in relation to national recommendations. Methods: A transversal study was conducted through administration of a questionnaire by personal interview. The following care units were involved: Paediatric, Neonatal, Cardiac Surgery and General Intensive Care Units and Infectious Diseases Unit. Results: The study sample comprised 308 HCWs. Half the sample were aware of the vaccination recommendations, with occupation and age found to be predictive factors (OR = 9.38, 95%CI: 2.07−42.41; OR = 0.36, 95%CI: 0.22−0.60). A higher percentage defined the diseases as a risk for their patients’ health, although this perception was lower in the over-40 age group. In several cases, there were statistically significant differences between the care units (p < 0.001). Around three-quarters of the sample agreed that vaccination should be mandatory; willingness to undergo a future booster vaccination was statistically correlated with the variables of age and care unit (p < 0.001, p = 0.03). Conclusion: The protection of health in the workplace can be achieved through some strategic actions, such as the implementation of educational strategies, and protocols for the monitoring of immunocompetence and the improvement of vaccination.

Risk of tuberculosis transmission by children to healthcare workers - a comprehensive review.

Healthcare workers (HCWs) are at increased risk of becoming infected with M. tuberculosis complex (Mtbc). To assess the magnitude of Mtbc transmission by children under the age of 15 years to HCW. Medline, Google Scholar and Cochrane library were searched to select primary studies in which a child was the presumed index case and exposed HCW were screened for latent TB infection (LTBI). Of 4,702 abstracts, 15 original case reports covering 16 children with TB were identified. In sum, 1,395 HCW were contact persons and underwent testing. Ten of the studies reported TST conversion, amounting to 35 (2.9%) of the 1,228 HCW tested. In three of the TST-based and both of the studies that used IGRA testing, conversion was absent. 12 of the 15 studies (80%) reported exposure of HCW in neonatal intensive units (NICUs) to premature infants suffering from congenital pulmonary TB. One study including two infants addressed possible pulmonary Mtbc transmission in a general pediatric ward. Extrapulmonary transmission by aerosolized Mtbc was suggested in two patients, an infant with tuberculous peritonitis and a 12-year-old adolescent with pleurisy, and culture-confirmed only after the child had undergone video-assisted thoracoscopic surgery. Routine use of protective facemasks by HCW before exposure was not mentioned in any of the included studies. The results suggest that the risk of Mtbc transmission from children to HCW is low. Particular attention should be paid to infection risk during respiratory manipulations in NICUs. The consistent wearing of facemasks may further reduce the risk of Mtbc transmission.

Invasive Fungal Infection Presenting as Early-Onset Neonatal Sepsis

In neonatal intensive units, invasive fungal infection remains a significant cause of morbidity and mortality, although an unusual cause of early-onset neonatal sepsis. In this report, we present a case of Candida parapsilosis infection presenting as early-onset bacterial sepsis. The patient was a 6-day-old male preterm neonate (estimated gestational age of 32 weeks) admitted to our neonatal unit on account of fever, refusal to feed, and vomiting which started during the first 24 h of life. Initially, he was managed for early-onset neonatal sepsis. However, his clinical state deteriorated within the 1st week of admission and his blood culture yielded C. parapsilosis. His clinical condition subsequently improved significantly following the administration of intravenous amphotericin. He spent a total of 25 days on admission before discharge. Our report reiterates the need to raise the index of suspicion for invasive fungal infection in cases of early-onset neonatal sepsis with poor response to appropriate and potent antibiotics.

Survey on Pattern and Determinants of Blood Transfusion in Benha Neonatal Intensive Unit

Survey on Pattern and Determinants of Blood Transfusion in Benha Neonatal Intensive Unit

Traumatic Birth Experience and Breastfeeding Ineffectiveness - a Literature Review.

A traumatic birth experience can affect the breastfeeding process and make it ineffective. The aim of this study was to identify the factors associated with breastfeeding ineffectiveness after birth trauma, through the world literature. There are several factors responsible for a traumatic birth experience, such as obstetric violence, postpartum complications and complications induced by doctors, invasive vaginal deliveries, emergency caesarean sections, admission of a neonate to the Neonatal Intensive Unit, past traumatic life events and mental health problems. The aim of this study was to identify the factors associated with breastfeeding ineffectiveness after birth trauma, through the world literature. An extended search was conducted to identify relevant for breastfeeding and traumatic birth experiences manuscripts for this study. Databases including PubMed, PsycINFO and Google Scholar. The search was limited to articles published in English the last decade. Factors that contribute to the ineffectiveness of breastfeeding after a traumatic birth are hormonal, medication, insufficient support from the partner, reliving the traumatic birth experience, past traumatic experiences in the woman's life and her mental state. The mental trauma during childbirth is complex and multifactorial. Therefore, it is necessary to take measures on the one hand to prevent mental trauma during childbirth and on the other hand to make interventions to deal with the consequences of the trauma on the mental health of the mother and on breastfeeding which is directly affected.

Is the Gestational Weight Gain Recommended by the National Academy of Medicine Guidelines Suitable for Chinese Twin-Pregnant Women with Gestational Diabetes Mellitus?

This study aimed to assess the applicability of the National Academy of Medicine (NAM) interim guidelines for twin pregnancies to the specific population of gestational diabetes mellitus by exploring the relationship between gestational weight gain and adverse pregnancy outcomes in Chinese twin-pregnant women with gestational diabetes mellitus. This was a retrospective cohort study of women diagnosed with diabetes in pregnancy between July 2017 and December 2020 at the Maternal and Child Health Hospital in Chongqing, China. The primary variable of interest was maternal total gestational weight gain. The primary outcomes were perinatal outcomes, which included: preeclampsia, small for gestational age, large for gestational age, low birth weight, neonatal pneumonia, neonatal respiratory distress syndrome, and neonatal intensive unit admission, etc. The association between inappropriate gestational weight gain and adverse pregnancy outcomes was estimated using multiple logistic regression analysis. A total of 455 twin-pregnant women who had gestational diabetes mellitus were analyzed. Women with low gestational weight gain had reduced risk of preeclampsia (adjusted odds ratio [aOR], 0.32; 95% CI or confidence interval, 0.17-0.63; p = 0.001) and their infants had higher risks of small for gestational age (aOR, 1.93; 95% CI, 1.04-3.58; p = 0.037), low birth weight (aOR, 2.27; 95% CI, 1.32-3.90; p = 0.003), neonatal intensive unit admission (aOR, 3.29; 95% CI, 1.10-5.78; p = 0.038), pneumonia (aOR, 2.41; 95% CI, 1.08-5.33; p = 0.031), and neonatal respiratory distress syndrome (aOR, 2.29; 95% CI, 1.10-4.78; p = 0.027); the infants of women with excessive gestational weight gain had a higher risk of large for gestational age (aOR, 3.76; 95% CI, 1.42-9.96; p = 0.008). Gestational weight gain controlled within the range recommended by the NAM could reduce the risk of perinatal adverse outcomes. The 2009 NAM gestational weight gain recommendations can be used for Chinese twin-pregnant women with gestational diabetes mellitus. · Inappropriate gestational weight gain can lead to adverse perinatal outcomes in twin pregnancies.. · Gestational weight gain controlled within recommended range could reduce the risk of poor perinatal outcomes.. · The National Academy of Medicine recommendations are suitable for Chinese twin-pregnant women with GDM..
