Maternal and neonatal group B streptococcus colonisation: A systematic review and the meta-analysis of matched-pair studies.

AIM: To determine the prevalence of group B Streptococcus (GBS) carriage among parturient women and neonates, and the relative risk of vertical transmission, the relative risk of early and late-onset GBS and the pooled incidence of early-late-onset GBS infection. METHODS: A systematic search of relevant cohort studies from three electronic databases to identify all relevant studies published up to 7 November 2022. The review was conducted in accordance with PRISMA guidelines. Estimates were pooled using random-effects meta-analyses. RESULTS: A total of 54 articles with 355 787 matched pairs of parturient women and neonates from 30 countries were included in the analysis. The pooled prevalence of GBS colonisation was 17.1% among the pregnant women and 1.0% among neonates. The pooled prevalence of vertical transmission of GBS was 4.5% and the pooled relative risk of GBS colonisation of neonates born to mothers with GBS was 9.9. CONCLUSION: We support the implementation of targeted intrapartum antibiotic prophylaxis for all women who are positive for GBS as well as women with risks factors for early onset GBS in their infants regardless of their GBS colonisation status.

Psychometric Features of the Edinburgh Postnatal Depression Scale Among Malaysian Women: A Cross-Sectional Study.

Background The Edinburgh Postnatal Depression Scale (EPDS) is a 10-item questionnaire developed to identify women at risk for postpartum depression (PD). EPDS symptom patterns appear to vary by nation. The EPDS items and their correlation with affirmative EPDS screens have thus far been minimally studied among Malaysians. Using positive predictive value (PPV) and negative predictive value (NPV), this study aims to evaluate the EPDS-based psychometric features of individual answer items. Methodology A cross-section of postpartum women receiving care at two tertiary care facilities in Malaysia underwent screening assessments in the course of receiving treatment. EPDS was employed with an aggregate cutoff score (≥12). EPDS items were assessed as predictors of abnormal EPDS screens. Results A total of 219 participants were screened, among which 66 were positive on the EPDS. EPDS item responses were collected (item responses 0-3: PPV = 0.07-0.78 and NPV = 0.93-0.22). A negative response to any item strongly predicted a negative EPDS screen (item entry = 0 and NPV = 0.93). Affirmative responses on items 8, 9, and 10 were particularly strong predictors of abnormal EPDS scores, while negative responses to items 3, 5, and 7 were strong predictors of negative EPDS scores. A substantial NPV for any item (response 0 and NPV items 1-10 = 0.93) and a moderate PPV for any affirmative response (responses 1-3, PPV items 1-10 = 0.60) were observed. Conclusions This is one of the few studies to examine the EPDS item responses among Malaysian women. The results suggest that depression remains prevalent in this postpartum population. Our findings reveal a robust NPV for any negative response to the individual items of the scale, a moderate PPV for any affirmative response, and a particularly robust validity for specific EPDS items. Physical complaints, rather than feelings of sadness, figure prominently in this population, suggesting a tendency among Malaysian women toward somatization.

The Associations of Breastfeeding and Postnatal Experiences With Postpartum Depression Among Mothers of Hospitalized Infants in Tertiary Hospitals.

Background Postpartum depression has been linked to undesirable outcomes for mother-infant dyads, interfering with childcare and breastfeeding practices. This study aimed to determine the prevalence of depressive symptoms among mothers during the postpartum period and its association with breastfeeding and postpartum experiences. Methodology This cross-sectional study involved mothers of hospitalized infants (n = 219) at two tertiary hospitals in Klang Valley, Malaysia. Mothers were screened for postpartum depression using the Edinburgh Postnatal Depression Scale with a cut-off of ≥12 for positive screening for depression. Mothers were asked to complete questionnaires on breastfeeding experience, which included breastfeeding self-efficacy and challenges. The questionnaires also collected information on postnatal experiences, including birth outcomes, anxiety and stress levels, and social support. Multiple linear regression was used to ascertain the association of postpartum depression levels with breastfeeding and postnatal experiences. Results Overall, 30% of mothers in this study screened positive for depression. Based on multiple linear regression, a higher score of postpartum depression was significantly associated with unpleasant breastfeeding and postnatal experiences reflected by increased scores of anxiety and stress, lower infant birth weight, increased breastfeeding problems, and lower level of social support (p < 0.005). Conclusions Maternal emotions, birth outcomes, breastfeeding issues, and social support were associated with postpartum depression. Efforts should be made to increase maternal support, and screening for maternal depression during infant hospital stays should be encouraged.

Isolation of Janthinobacterium lividum from early onset neonatal sepsis patients in Malaysia.

BACKGROUND: The term early onset neonatal septicaemia (EONS) refers to invasive bacterial infections that primarily involve the blood stream of neonates during the first 3 days of life. Although early onset neonatal septicaemia is relatively uncommon, it may be associated with case fatality rates of 15-30% and substantial morbidity in surviving infants. OBJECTIVES: This study describes an unusual septicaemia cases with Janthinobacterium lividum in neonatal Intensive Care Units. METHODS: Bacterial causes of early onset neonatal sepsis in Kuala Lumpur Hospital Malaysia were investigated using broad range 16S rDNA PCR and sequencing. The bacterial DNA was isolated directly from blood without pre-incubation. All samples collected were equally cultured and incubated in automated BACTEC system. RESULTS: Two hundred and fifty two neonates were recruited in this study with mean (SD) gestational age of 35.9. Neonates with J. lividum infection lacked microbiological evidence of septicaemia as their blood culture yielded no bacterial growth. However, the PCR analysis of these samples yielded 1100bp corresponding to bacteria species. CONCLUSION: This study demonstrates the value of PCR in detecting bacteria where special growth requirement is involved.

Pneumococcal glomerulonephritis in a healthy child: a case report and literature review.

Pneumococcal glomerulonephritis is rarely described in the literature. We report a four-year-old boy who developed acute glomerulonephritis following pneumococcal bacteraemia and submandibular lymphadenitis, and review the published literature. Two weeks after developing acute glomerulonephritis, the patient developed bronchopneumonia with left pleural effusion. However, by the fourth week of admission, his renal function had normalised and lung involvement resolved.
