Antenatal Depression and its Associated Factors: Findings from Kuwait Birth Cohort Study.

BACKGROUND: Pregnant and postpartum women are at high risk of depression due to hormonal and biological changes. Antenatal depression is understudied compared to postpartum depression and its predictors remain highly controversial. AIM: To estimate the prevalence of depressive symptoms during pregnancy and investigate factors associated with this condition including vitamin D, folate and Vitamin B12 among participants in the Kuwait Birth Study. METHODS: Data collection occurred as part of the Kuwait Birth Cohort Study in which pregnant women were recruited in the second and third trimester during antenatal care visits. Data on antenatal depression were collected using the Edinburgh Postnatal Depression Scale (EPDS), considering a score of ≥ 13 as an indicator of depression. Logistic regression was used to investigate factors associated with depressive symptoms in pregnant women. RESULTS: Of 1108 participants in the Kuwait Birth Cohort study, 1070(96.6%) completed the EPDS. The prevalence of depressive symptoms was 21.03%(95%CI:18.62-23.59%) and 17.85%(95%CI:15.60-20.28%) as indicated by an EPDS ≥ 13 and EPDS ≥ 14 respectively. In the multivariable analysis, passive smoking at home, experiencing stressful life events during pregnancy, and a lower level of vitamin B12 were identified as predisposing factors. Conversely, having desire for the pregnancy and consumption of fruits and vegetables were inversely associated with depressive symptoms. CONCLUSION: Approximately, one fifth of pregnant women had depressive symptoms indicating the need to implement screening program for depression in pregnant women, a measure not systematically implemented in Kuwait. Specifically, screening efforts should focus on pregnant women with unintended pregnancies, exposure to passive smoking at home, and recent stressful live events.

WHO infant and young child feeding indicators in relation to anthropometric measurements.

OBJECTIVE: This study aimed to report the WHO infant and young child feeding (IYCF) indicators from Kuwait and to investigate the associations between these indicators and anthropometric measurements. DESIGN: The Kuwait Nutritional Surveillance System uses observational cross-sectional approach to collects data by face-to-face interviews with mothers or child guardians using a structured questionnaire that was developed based on the WHO IYCF indicators. The weight and height of infants and young children were measured using digital scales in a standardised manner. SETTING: Vaccination centres in all governorates (provinces) of Kuwait. PARTICIPANTS: Infants and young Kuwaiti children aged 0-23 months (N 5839). RESULTS: The prevalence of exclusive breastfeeding and age-appropriate breastfeeding were 8·0 and 7·4 %, respectively. The prevalence of stunting and wasting was 7·5 and 2·4 %, respectively, while the prevalence of overweight and obesity was 6·5 and 1·6 %, respectively. In the multivariable analysis, exclusive breastfeeding and age-appropriate breastfeeding were more common in children with stunted growth (AOR 1·71 (95 % CI 1·08, 2·70; P = 0·021) and 1·44 (95 % CI 1·01, 2·06; P = 0·046), respectively). The introduction of solid/semisolid or soft foods was inversely associated with stunting (AOR 0·52; 95 % CI 0·30, 0·90; P = 0·021). Only age-appropriate breastfeeding was inversely associated with overweight (AOR 0·62; 95 % CI 0·39, 0·98; P = 0·043). CONCLUSION: Our findings showed that indicators of breastfeeding are low in Kuwait. Our findings suggest that the associations between different WHO IYCF indicators and stunting as well as overweight is complex, which highlights the need for a better understanding of WHO IYCF indicators in both low- and high-income countries.

Vitamin D deficiency in mothers, neonates and children.

Vitamin D is produced in response to the exposure of skin to sunlight through UV-B synthesis. It can also be obtained from diet and dietary supplements. Vitamin D is essential for strong bones as it helps to absorb calcium from diet. Vitamin D deficiency mainly occurs if strict vegetarian diet is followed as mostly the source of vitamin D is animal based; therefore, exposure to sunlight is restricted or having dark skin color. Low vitamin D levels results in increased possibility of gestational diabetes among pregnant women, low birth weight and pre-eclampsia in infants, and mothers may suffer bone impairment, osteoporosis, hypocalcaemia, and hypertension. Vitamin D deficiency is directly linked with severe complication in mothers and neonates, causing rickets, poor fetal growth and infantile eczema in neonates. Higher prevalence rate of vitamin D deficiency has led professionals to emphasize on development of relevant precautionary measures.

Cytokine profiles at birth and the risk of developing severe respiratory distress and chronic lung disease.

BACKGROUND: Neonates with the diagnosis of respiratory distress syndrome (RDS) were studied to investigate possible associations between cytokine levels at birth and developing severe RDS or chronic lung disease (CLD). MATERIALS AND METHODS: This was a cross-sectional study on serum and bronchoalveolar lavage (BAL) samples collected within hours of birth from infants with moderate and severe RDS. Twenty infants with moderate RDS and 20 infants with severe RDS were studied. RDS was diagnosed on the basis of radiographic findings, respiratory distress, and an increasing oxygen requirement. RDS severity was graded based on the radiological findings and Downe's Score. CLD was diagnosed when infants were still on supplemented O2 by at least 28 days of age. Levels of the cytokines interleukin (IL)-1ß, IL-6, IL-8, IL-10, and tumor necrosis factor alpha were measured using enzyme-linked immunosorbent assay. "Statistical analysis was performed using the SPSS for Windows, (SPSS Inc., Chicago, IL, USA)." RESULTS: Levels of the proinflammatory cytokines IL-8 and IL-1ß were significantly higher in BAL of infants with severe RDS than those with moderate RDS (P = 0.007 and P = 0.02, respectively). IL-8 levels were also significantly higher in BAL and serum of infants who later progressed to CLD than in those who did not (P = 0.03 for both). The IL-8/IL-10 cytokine ratio was significantly higher in the BAL of severe RDS infants than in moderate RDS (P = 0.01) and in the serum of infants who progressed to CLD than in those who did not (P = 0.03). CONCLUSION: Levels of IL-8 and the IL-8/IL-10 ratio measured soon after birth were associated with severity of RDS as well as progression to CLD. Early measurement of cytokines levels and ratios may contribute to the prognosis and management of RDS and CLD.

Late-onset neonatal sepsis in Arab states in the Gulf region: two-year prospective study.

OBJECTIVES: This study aimed to investigate the incidence of late-onset sepsis (LOS) in neonatal intensive care units (NICUs) in Arab states in the Gulf region and to describe the main causative organisms and their antibiotic resistance. METHODS: This observational prospective cohort study was conducted over a 2-year period in five NICUs in Kuwait, Saudi Arabia, and the United Arab Emirates. LOS was defined as the growth of a single potentially pathogenic organism from blood or cerebrospinal fluid in infants >3days of age with clinical and laboratory findings consistent with infection. RESULTS: Seven hundred and eighty-five cases of LOS occurred among 67 474 live births. The overall incidence of LOS was 11.63 (95% confidence interval (CI) 10.84-12.47) per 1000 live births, or 56.14 (95% CI 52.38-60.08) per 1000 admissions. Coagulase-negative staphylococci and Klebsiella spp were the most common organisms, causing 272 (34.65%) and 179 (22.80%) of LOS cases, respectively. No evidence of a seasonal variation in the incidence of Klebsiella spp or in the incidence of all Gram-negative organisms was found. More than half of the Klebsiella spp were resistant to third-generation cephalosporins. CONCLUSION: LOS poses a major burden in this area, which could be due to the increasing care of premature babies. Gram-negative organisms, particularly Klebsiella spp, are having an increasing role in LOS in this region, with high levels of resistance to third-generation cephalosporins. NICUs in the area should create a platform through which to share experience in reducing neonatal sepsis and contribute to a common antibiotic stewardship program.

Culture-proven early-onset neonatal sepsis in Arab states in the Gulf region: two-year prospective study.

OBJECTIVE: To investigate the incidence and the pattern of causative organisms of culture-proven early-onset sepsis (EOS) in Arab states in the Gulf region. METHODS: Five neonatal care units participated in this 2-year prospective study in Kuwait, the United Arab Emirates, and Saudi Arabia. Data were collected prospectively using a standardized data collection form. EOS was defined as the growth of a single potentially pathogenic organism from blood or cerebrospinal fluid in infants within 72h of birth, with clinical and laboratory findings consistent with infection. RESULTS: Out of 67 474 live births, 102 cases of EOS occurred. The overall incidence of EOS was 1.5 (95% confidence interval 1.2-1.8) per 1000 live-births, ranging from 2.64 per 1000 live-births in Kuwait to 0.40 per 1000 live-births in King Abdulaziz Hospital in Saudi Arabia. The most common causative organism of EOS was group B Streptococcus (GBS; 60.0%), followed by Escherichia coli (13%). The incidence of invasive GBS disease was 0.90 per 1000 live-births overall and ranged from 1.4 per 1000 live-births in Kuwait to 0.6 per 1000 live-births in Dubai Hospital. CONCLUSIONS: The incidence of EOS and the patterns of the causative organisms in the Arab states in the Gulf region are similar to those in developed countries before the era of intrapartum antibiotic prophylaxis. Efforts should be made to improve intrapartum antibiotic prophylaxis in the Arab state setting, which could avert large numbers of GBS infections.

Use of palivizumab with other infection control measures to control respiratory syncytial virus outbreaks in neonatal care units.

OBJECTIVE: No guidelines exist on the use of palivizumab during outbreaks of Respiratory Syncytial Virus (RSV) in Neonatal Intensive Care Units (NICUs). We aimed to describe an outbreak of RSV in NICU settings and the role of palivizumab in controlling the outbreak. METHODS: The index case was a 30-day-old premature infant. During the outbreak, 13 cases of RSV were confirmed by RT-PCR. All infants in the NICU received palivizumab after RSV diagnosis. RESULTS: Of the 13 cases, seven were male; and the median (interquartile) of birth weight was 1585 (IQR: 1480-1705) g. All cases were premature under 34-weeks-gestation. Age at onset of disease varies between 10 and 160 days. Only four cases occurred after administering palivizumab and applying other infection control measures. CONCLUSION: During nosocomial outbreaks of RSV, administration of palivizumab to all infants in NICU appears to be rational and may help contain outbreaks.

Persistent candidemia in neonatal care units: risk factors and clinical significance.

OBJECTIVES: The prevalence and clinical significance of persistent candidemia among neonates are poorly understood. This study aimed to describe the rate and the clinical relevance of persistent candidemia over a 4-year period in Kuwait. METHODS: A retrospective chart review of infants admitted to the Neonatal Care Unit of the Maternity Hospital in Kuwait between January 2007 and December 2010, who had a positive blood culture for Candida species, was conducted. Persistent candidemia was defined as the isolation of the same Candida species more than 6 days after the initiation of antifungal therapy, or death due to candidemia within 6 days of antifungal treatment. Stepwise logistic regression was used to investigate factors associated with persistent candidemia. RESULTS: Of 89 neonates with a Candida infection, 54 (60.7%, 95% confidence interval 49.7-70.9%) had persistent candidemia. The case-fatality rate was 54% among those with persistent candidemia and 3% among those with non-persistent candidemia (p<0.001). Neonates with persistent candidemia were more likely to be female, have a central vascular catheter at diagnosis, and have a low platelet count. All isolated Candida species were susceptible to antifungal agents. CONCLUSIONS: Persistent candidemia is common among neonates with a Candida infection and is associated with an increased risk of mortality. Drug resistance is unlikely to explain the persistent candidemia; host-related factors seem to be more important and hence could be used to identify those at risk in order to institute appropriate preventive and treatment measures.

Neonatal infections in China, Malaysia, Hong Kong and Thailand.

OBJECTIVE: Neonatal sepsis is a major cause of neonatal deaths in Asia but data remain scarce. We aimed to investigate the causative organisms and antibiotic resistance in neonatal care units in China, Malaysia, Hong Kong and Thailand. METHODS: Prospective cohort study of neonatal sepsis defined as positive culture of a single potentially pathogenic organism from blood or cerebrospinal fluid differentiated into early-onset sepsis (EOS) occurring <3 days of birth and late-onset sepsis (LOS) ≥3 days after birth. RESULTS: During the study period, there were 963 episodes of neonatal sepsis. The incidence of EOS was 0.62 (95% CI 0.45 to 0.82) per 1000 live births or 4.91 (95% CI 4.22 to 5.68) per 1000 admissions while the incidence of LOS was 5.00 (95% CI 4.51 to 5.53) per 1000 live births or 21.22 (95% CI 19.79 to 22.77) per 1000 admissions. The incidence of Group B Streptococcus (GBS) sepsis was low but remained the most common single pathogen for EOS among inborn babies. Klebsiella spp. was the most common Gram-negative organism causing most deaths. The case-fatality was 7.0% (95% CI 3.9% to 12.0%) for EOS and 16.0% (95% CI 13.7% to 19.0%) for LOS, and was significantly different between participating units after adjusting for potential confounders. Of all Gram-negative organisms, 47%, 37% and 32% were resistant to third-generation cephalosporins, gentamicin or both, respectively. CONCLUSIONS: The pattern of EOS in Asian settings is similar to that in industrialised countries with low incidence of GBS sepsis. The important features of neonatal sepsis in Asia are the burden of Klebsiella spp. and high level of antibiotic resistance. These should be addressed while developing measures to reduce neonatal mortality due to infection.

Incidence, aetiology and resistance of late-onset neonatal sepsis: a five-year prospective study.

AIM: Investigate the incidence, etiological pattern and the antimicrobial resistance of late-onset neonatal infections over a period of 5 years. METHODS: Longitudinal audit of neonatal sepsis from January 2005 to December 2009, in the main maternity hospital in Kuwait. Late-onset neonatal infection was defined as the culture of a single potentially pathogenic organism from blood or cerebrospinal fluid from an infant older than 6 days in association with clinical or laboratory findings consistent with infection. RESULTS: The overall incidence was 16.9 (95% confidence interval: 15.8-18.0) episodes per 1000 live births. The commonest pathogen was coagulase-negative Staphylococcus, 339 (35.7%), while Klebsiella was the most common gram-negative infection, 178 (18.8%). Escherichia coli, Enterococcus and Enterobacter spp were each responsible for 6% of all infections. Candida caused 104 (11.0%) infections. The general pattern of infection remained unchanged over the study period. Case fatality was 11.7% (95% confidence interval: 9.7-13.9%) and was high for Pseudomonas (18.4%) and Candida (22.1%) infections. Approximately 24 and 20% of Klebsiella infections were resistant to cefotaxime and gentamicin, respectively, while 28 and 24% of Escherichia coli infections were resistant to cefotaxime and gentamicin, respectively. CONCLUSION: The incidence of late-onset infection in Kuwait is high, resembling that in resource-poor countries. The high incidence coupled with low case fatality provides an example for settings where tertiary care is introduced without strict measures against nosocomial infections. Prevention against nosocomial infections in neonatal units has the potential to further reduce neonatal mortality in these settings.

Childhood obesity and academic achievement among male students in public primary schools in Kuwait.

OBJECTIVE: The aim of this study was to investigate the association between childhood obesity and student academic performance in the classroom setting. SUBJECTS AND METHODS: A multi-stage cluster random sampling was used to select a representative sample of 1,213 fifth-grade students in male public schools. Height and weight were measured using a standard protocol. Overweight was defined as BMI ≥85th but <95th percentile, while obesity as ≥95th BMI percentile, using growth charts provided by the Centre for Disease Control and Prevention (2000). Data on each student's academic performance and sociodemographic factors were extracted from school records. Of the 1,213 students, 147 were absent on the day the survey was conducted. Therefore, the analysis was based on 1,066 students. Of the 1,066 students, 67 did not have previous school records because they were new in the school; hence the association between school performance and obesity was based on 999 students. RESULTS: The prevalence of obesity was 186 (17.4%, 95% CI: 15.2-19.9%) while the prevalence of overweight was 232 (21.8%, 95% CI: 19.3-24.4%). There was no significant association between obesity and academic performance after adjusting for sociodemographic factors. Parental education was the most important predictor for high academic performance in the classroom setting. CONCLUSION: There is no association between obesity and academic performance in the classroom setting among boys in Kuwait. With the lack of evidence of a relationship between childhood obesity and academic performance, using high performance as a measure of success in prevention initiatives cannot be justified.

Knowledge, misconceptions, and future intentions towards breastfeeding among female university students in Kuwait.

A cross-sectional study using a self-administered questionnaire was conducted on female university students (N = 1106) to explore their knowledge and misconceptions on breastfeeding. Most participants recognized the benefits of breastfeeding, but only a few were aware of the recommendation for exclusive breastfeeding in the first 6 months of life. Misconceptions were common; 66%, 60%, and 55% of participants thought mothers should temporarily stop breastfeeding if they had a fever, skin rash, or sore throat, respectively. Approximately 20% thought mothers should stop breastfeeding if the child had diarrhea, vomiting, or skin rash. Support of breastfeeding in public places was low, but 38% supported breastfeeding in female prayer rooms in public places. Efforts should be made to correct common misconceptions on breastfeeding and increase the support of breastfeeding in public places among university students. Female prayer rooms that exist in all public places in Kuwait can be used to promote breastfeeding in public places in Kuwait.

Pattern and etiology of culture-proven early-onset neonatal sepsis: a five-year prospective study.

OBJECTIVES: To investigate the incidence of early-onset neonatal sepsis and identify the main pathogens over a 5-year period in Kuwait. METHODS: Blood samples were collected from all infants with any clinical or laboratory feature suggestive of sepsis, at the main maternity hospital in Kuwait. Cases of early-onset neonatal infection were defined as culture of a single potentially pathogenic organism from blood or cerebrospinal fluid from infants younger than 7 days of age, in association with clinical or laboratory findings consistent with infection. RESULTS: The overall incidence of early-onset neonatal infection was 2.7 (95% confidence interval (CI) 2.3-3.2) episodes per 1000 live-births. The case-fatality was 13.1% (95% CI 8.6-18.9%). Group B Streptococcus (GBS) accounted for 17.6% of infections among infants younger than 7 days (incidence 0.48 per 1000 live-births), but 38.1% of infections in the first 2 days of life. Neither the incidence of early-onset infection by GBS nor by Escherichia coli changed significantly over the study period. CONCLUSIONS: Although the incidence of GBS infections was relatively low, GBS accounted for most early-onset infections. Intrapartum antibiotic prophylaxis against GBS should be strengthened. There was no evidence to suggest that early-onset infection due to non-GBS organisms such E. coli has increased in the last 5 years.

Comparison between different types of surveillance samples for the detection of GBS colonization in both parturient mothers and their infants.

OBJECTIVE: To find the optimum screening method in detecting group B streptococcal (GBS) colonization in both mother and infant, and to identify the risk factors that influence GBS colonization in the infants. PATIENTS AND METHODS: 1,120 singleton pregnant women were evaluated for GBS colonization by combined lower vaginal-anorectal swabs (LVRS) and urine tests, while their infants were evaluated for colonization with skin, ear and gastric aspirate samples. RESULTS: LVRS swabs were positive in 14.2% of mothers while urine was positive in 7.6%. Among the infants skin, ear and gastric aspirate samples were positive in 7.0, 6.9 and 3.5%, respectively. Prolonged rupture of the membrane was the only significant factor associated with colonization in these infants (p < 0.001). CONCLUSIONS: Lower vaginal-anorectal swab is an effective method in detecting colonization in mothers especially when combined with urine culture. Skin or ear swabs are equally effective in detecting colonization in neonates. GBS colonization rate in our parturient and neonatal population is comparable to that was reported from other countries. A well-developed screening program and appropriate management strategies for both GBS colonized mothers and infants are recommended.

Incidence and risk factors associated with the patency of ductus arteriosus in preterm infants with respiratory distress syndrome in Kuwait.

OBJECTIVE: Patent ductus arteriosus (PDA) is considered to be an important cause of morbidity and mortality among preterm infants. The aim of this study is to determine the incidence of PDA in ventilated preterm infants with respiratory distress syndrome (RDS) and to evaluate the role of some antenatal risk factors on its occurrence in our population. METHODS: The case records of the preterm infants of <34 weeks gestational age, who were ventilated for RDS at the neonatal intensive care unit of Maternity Hospital, Safat, Kuwait, between March 1998 and February 1999, were reviewed. Diagnosis of PDA was based on echocardiographic findings. The association between the risk factors chosen and the PDA was also evaluated. RESULTS: A total of 101 infants whose gestational ages ranged between 25-33 weeks, and birth weights between 685-1580 grams were included. Fifty-four had a significant PDA (53.4%). Maternal diabetes and antepartum hemorrhage (APH), birth weights, gestational ages, multiplicity and gender of the infants were found to be related to the incidence of PDA. CONCLUSION: The incidence of PDA in our ventilated preterm infants with RDS is similar to those reported from other neonatal units outside Kuwait. There are some factors that may identify babies, who are prone to develop PDA, which need to be confirmed by further prospective studies using a larger population.

Development of chronic lung disease in preterm infants treated with surfactant.

BACKGROUND: Chronic lung disease (CLD) is generally known to develop among preterm infants who have severe respiratory distress syndrome (RDS) at birth. Many clinical trials have established the efficacy of surfactant replacement therapy to treat RDS at birth with differing doses. In this study, the preterm infants diagnosed to have RDS at birth and treated with one or two doses of surfactant, depending on the severity of the RDS, were studied to evaluate the effect of surfactant on the later development of CLD. METHODS: A retrospective examination of case records of preterm infants who were born at < or = 28 weeks gestation period were studied. The subjects received a natural surfactant product (survanta) between September 1994 and April 1996 at the Monash Medical Center, Australia. RESULTS: Despite less severe initial lung disease, the subsequent respiratory outcome of infants who received one dose of surfactant, showed a trend towards being poorer compared to those who were diagnosed as having severe RDS at birth and received two doses of surfactant. At the corrected gestational age of 36 weeks, 54% of those infants began with mild RDS required oxygen, while only 44% of those who started with a severe RDS required supplemental O2. CONCLUSION: This study reports the infants with severe RDS at birth had responded slightly better or equally, compared to those with mild RDS, in terms of later development of CLD under surfactant treatment proportional to the severity.
