Clinical and Nutritional Determinants of Extrauterine Growth Restriction Among Very Low Birth Weight Infants

Purpose

To identify the clinical and nutritional factors associated with extrauterine growth restriction (EUGR) among very low birth weight infants (VLBW) in a tertiary hospital in Jordan.

Patients and Methods

We conducted a retrospective analysis of all VLBW infants admitted at King Abdullah University Hospital between July 2015 and June 2020. Clinical factors, nutritional intake, and growth parameters were collected and analyzed. A multilogistic regression model was applied to identify factors associated with EUGR.

Results

Of the 247 VLBW infants included in analysis, 112 (45%) were males, 30 (12%) were below 1000 g, and 72 (29%) were small for gestational age (SGA). EUGR was diagnosed in 198 (80%) at discharge. The rates of EUGR among SGA and non-SGA infants were 97% and 73%, respectively. The EUGR infants had a higher gestational age (30.7 vs 29.8 weeks, p=0.04), a lower birth weight (1209 vs 1300 g, p=0.005), a longer ventilatory support (5.7 vs 2.2 days, p=0.03), a higher incidence of sepsis (23% vs 10%, p=0.05), and a longer hospitalization (46 vs 38 days, p=0.03). With multilogistic regression model, the factors associated with EUGR include small-for-gestational age (AOR 9, 95% C.I. 2, 50), >3-day delay in feeding initiation (AOR 3.8, 95% C.I. 1.2,10), >14-day delay in achieving full feeds (AOR 3.3, 95% C.I. 1.2, 8), <3 g/kg of protein intake on the 8th day (AOR 2.1, 95% C.I. 1.1, 4.1), <100 kcal/kg of total caloric intake on the 15th day (AOR 3.8, 95% C.I. 1.6, 8.9), and occurrence of sepsis (AOR 3, 95% C.I. 1.1, 9).

Conclusion

The rate of EUGR in our unit is high. In addition to being SGA at birth, sepsis and suboptimal protein and caloric intake in the first two weeks of life were significantly associated with this complication. A more aggressive enteral and parenteral nutritional approach is needed to minimize postnatal growth delay.

Prevalence and outcome of acute kidney injury, as defined by the new Kidney Disease Improving Global Outcomes guideline, in very low birth weight infants

AIM

To evaluate the prevalence, risk factors and outcome of acute kidney injury (AKI) in very low birth weight (VLBW) infants.

METHODS

In this retrospective study of VLBW infants, we analyzed the prevalence of AKI, as defined by changes in serum creatinine and urine output, associated risk factors and outcomes.

RESULTS

A total of 293 VLBW infants (mean gestational age 28.7 wk) were included, of whom 109 weighed less than 1000 g at birth. The overall prevalence of AKI was 11.6% (22% in infants with a birth weight under 1000 g and 5.4% those heavier). A total of 19 (55%) affected infants died, with a mortality rate of 58% in infant less than 1000 g and 50% in those heavier. After adjusting for confounding variables, only necrotizing enterocolitis (NEC) remained associated with AKI, with odds ratio of 4.9 (95%CI: 1.9-18.6). Blood pressure and glomerular filtration rate (GFR) were not different between affected infants and the others upon discharge from hospital. A normal GFR was documented in all affected infants at one year of age.

CONCLUSION

Using Kidney Disease Improving Global Outcomes definition of AKI, it occurred in over 10% of VLBW infants, more commonly in infants with lower birth weight. NEC was an independent associated risk factor. Renal function, as defined by GFR, was normal in all surviving affected infants 10 to 12 mo later.

Severe Hypotension After Amlodipine Use for Hypertension in a Newborn on Beta Blocker Therapy for Thyrotoxicosis

A 35-year-old woman with a 9-year history of Grave’s disease delivered a male infant weighing 2,210 g at 32 weeks of gestation by caesarean section. The neonate developed thyrotoxicosis and, at the age of 24 h, was treated with oral carbimazole (500 µg every 8 h) and propranolol (2 mg/kg/day in two divided doses). He subsequently developed hypertension on day 4, which required therapy with amlodipine (0.1 mg once daily). Severe hypotension developed within 24 h and required discontinuation of amlodipine, with initiation of intravenous inotropic support with dopamine and dobutamine (at a rate of 20 µg/kg/min). The blood pressure rapidly normalized, and both dopamine and dobutamine infusions were stopped within 36 h. A Naranjo assessment score of 6 was calculated, indicating that the severe hypotension was a probable adverse drug reaction caused by the combination of amlodipine and propranolol therapy.

The psychosocial functioning of mothers of infants admitted to the neonatal intensive care unit in the north of Jordan

The primary aim of this study was to assess the effect of admission of infants to neonatal intensive care unit (NICU) on the psychosocial functioning of their mothers. The secondary aim was to compare the psychosocial functioning of the mothers of infants admitted to NICU and the mothers of infants born at term and not admitted to NICU. A total of 75 consecutive mothers of infants admitted to NICU and 75 consecutive mothers of infants born at term and not admitted to NICU were included in the study. Mothers completed State-Trait Anxiety Inventory for Adults and Edinburgh Postnatal Depression Scale in three large hospitals in Irbid, Jordan in the period between November 2010 and June 2011. The results showed that mechanical ventilation, lower birth weight and lower gestation age were predictors of higher anxiety level and depression among mothers of infants admitted to NICU. Both groups (mothers of infants admitted to NICU and mothers of infants born at term and not admitted to NICU) scored high in Edinburgh Postnatal Depression Scale.

Characteristics of women visiting an infertility clinic and their interest in preimplantation sex selection in the north of Jordan

OBJECTIVES

To describe the characteristics of women attending a fertility clinic for infertility treatment and to determine their interest in the use of preconception sex selection and its associated factors.

METHODS

A cross-sectional study was conducted among women who presented to the fertility clinic in the IVF center for infertility treatment. A total of 335 women were included in the study and interviewed using the study questionnaire, which included information on patients' demographics, obstetric and infertility history, child gender preference, and interest in preconception sex selection.

RESULTS

A total of 155 (46.3%) women had primary infertility and 180 (53.7%) had secondary infertility. While preference for a boy was reported by 50 (14.9%) participants and preference for a girl was reported by seven (2.1%), the majority of women (83.0%) had no preference for gender. A total of 59 (17.6%) women showed an interest in using preconception sex selection. In the multivariate analysis, women who preferred a boy were more likely to be interested in preconception sex selection (OR=3.52) compared to women who had no preference for gender. Trying to conceive for ≥2 years was associated with an 80% increase in the odds of being interested in preconception sex selection.

CONCLUSIONS

The majority of women (83.0%) had no gender preference. Less than one fifth of women (17.6%) showed an interest in using assisted method for sex selection. Preference for a boy and trying to conceive for ≥2 years were significantly associated with increased odds of being interested in using preconception sex selection.

Pitfalls in measuring cerebrospinal fluid glycine levels in infants with encephalopathy

In encephalopathic infants, cerebrospinal fluid hyperglycinemia and elevated cerebrospinal fluid to plasma glycine ratio are considered pathognomonic of nonketotic hyperglycinemia. To evaluate the significance of cerebrospinal fluid hyperglycinemia and elevated cerebrospinal fluid to plasma glycine ratio in acutely encephalopathic infants, a retrospective chart review of all cases of isolated elevation of cerebrospinal fluid glycine levels at Arkansas Children's Hospital from January 1995 to December 2000 was performed. Twenty-two patients (14 males) were included. The most common diagnosis was hypoxic ischemic encephalopathy (n = 8). Nine patients had elevated cerebrospinal fluid to plasma glycine ratio, which was transient in 7 patients. This study shows that elevated cerebrospinal fluid to plasma glycine ratio can be encountered in a variety of clinical conditions. The significance of this observation in light of the poor prognosis of nonketotic hyperglycinemia and the possible role of glycine in the mechanism of ischemic neuronal injury is addressed.

Attitudes of graduating medical doctors toward using sex selection techniques in Jordan in 2009

OBJECTIVES

The aim of this study was to describe the attitude of graduating medical doctors toward the use of sex selection techniques in Jordan in 2009. MATERIALS AND METHODS (DESIGN): A self-administered questionnaire was used to assess attitude toward using sex selection. Demographic variables, gender preference of future children, and score on attitude toward using technology scale were used as independent variables.

RESULTS

A total of 254 doctors (178 males, 76 females) completed the questionnaire. Forty-one (16.1%) doctors thought that sex selection as PGD should be strictly prohibited and 45 (17.7%) thought it should be allowed freely. More than half (54.7%) of them thought it should only be available for medical reason. Only 59 (23.2%) reported that they may consider the use of sex selection technology to choose their future children. Participants who preferred their firstborn child to be a boy or those who preferred their first born child to be a girl were more likely to use sex selection than those without preference. Christian participants were more likely to use sex selection technology than Muslim participants, 9 (47.4%) versus 50 (21.3%). For each one-point increase in Attitude score, the odds of using sex selection increased by 20%.

CONCLUSIONS

The majority of graduating medical doctors believed that sex selection should be restricted and they were not willing to use it.

Clinical features of neonatal sepsis caused by resistant Gram-negative bacteria

BACKGROUND

Clinical features and outcomes of neonatal sepsis caused by resistant Gram-negative bacteria are not well described in Jordan. The aim of the present study was therefore to describe microbiology and clinical features, laboratory findings and outcomes of early- and late-onset Gram-negative neonatal sepsis.

METHODS

All patients with Gram-negative bacteremia between July 2003 and June 2005 were retrospectively included. Resistance profiles, clinical features and outcomes of early and late-onset neonatal sepsis were compared.

RESULTS

A total of 79 patients (after excluding all nine cases of Gram-positive bloodstream infection (BSI) were identified as having Gram-negative BSI (25 had early-onset and 54 had late-onset neonatal sepsis). Respiratory distress, metabolic acidosis and requirement of ventilation were found in 74.7%, 40.5%, and 58.2%, respectively. Hypotension was found in 22.9% of patients. Klebsiella pneumoniae was responsible for 43 cases (54.4.2%). Klebsiella pneumoniae resistance rates to ampicillin and ceftazidime were 100% and 50%, respectively. Mortality rate was 30.9%. Forty-eight percent of deaths occurred within 3 days of sepsis. Meningitis was diagnosed in five cases. Elevated C-reactive protein (CRP) and thrombocytopenia were seen in 28% and 24% of infants with early-onset sepsis, respectively, and in 79.6%, 59.3% of infants with late-onset sepsis respectively.

CONCLUSION

Both early- and late-onset neonatal sepsis are caused by highly resistant Gram-negative bacteria. Mortality of sepsis is high. Elevated CRP and thrombocytopenia is seen more commonly in late-onset neonatal sepsis.

Sex preference and interest in preconception sex selection: a survey among pregnant women in the north of Jordan

BACKGROUND

Preconception sex selection for non-medical reasons is a controversial issue in bioethics. Little research has described preferences for preconception sex selection among Arab populations. This study describes the sex preference and interest in employing sex selection techniques among pregnant women in northern Jordan.

METHODS

A self-reported questionnaire was administered to 600 pregnant women in Irbid, Jordan. chi(2) test and binary logistic regression were used to examine the factors associated with interest in preconception sex selection.

RESULTS

In general, the interest in using sex selection was low. Women who preferred boys were more likely to be interested in sex selection, if paid for by the couple [odds ratio (OR) = 4.40, 95% confidence interval (CI): 1.75-11.11] or by health insurance (OR = 3.42, 95% CI: 1.94-6.06), or, if feasible, administered through oral medication (OR = 8.84, 95% CI: 5.05-15.63). Women with lower education were more likely to be interested in sex selection, if paid by health insurance (OR = 1.96, 95% CI: 1.10-3.45) and were more likely to believe that sex selection is legal (OR = 1.79, 95% CI: 1.06-2.86). Women who had no boys were more likely to be interested in sex selection, if paid by health insurance (OR = 1.94, 95% CI: 1.10-3.42) or, if feasible, through medication (OR = 3.03, 95% CI: 1.82-5.00).

CONCLUSIONS

The majority of participants were not in favor of using preconception sex selection. Those with a preference to have boys, with lower education, and those with an imbalanced family were more likely to be interested in using sex selection technology.

Renal impairment and hydronephrosis in a premature infant following morphine infusion: case report

This is a case report of an association between morphine administration and occurrence of hydronephrosis with acute renal failure. This premature female infant born at 27 weeks of gestation had moderate hydronephrosis with acute renal impairment while receiving morphine infusion for pain management after chest-tube insertion. All these findings were reversed after stopping morphine and urinary catheterization. Follow-up renal ultrasound and voiding cystourethrogram showed resolution of hydronephrosis with no evidence of vesicoureteral reflux. Morphine is associated with reversible hydronephrosis and renal impairment in premature infants.

Diagnostic markers for neonatal sepsis: comparing C-reactive protein, interleukin-6 and immunoglobulin M

This clinical study was conducted to evaluate the diagnostic value of C-reactive protein (CRP), interlekin-6 (IL-6) and immunoglobulin M (IgM) in the early diagnosis of neonatal sepsis. The diagnostic values of each marker separately or in combinations were evaluated. The optimal cut-off values of each marker in the diagnosis of neonatal sepsis were defined. Between December 2004 and March 2005, a total of 78 neonates at different ages with different diagnoses in a neonatal intensive care unit in North Jordan were enrolled. Patients were classified into 'sepsis' group, 'probable sepsis' group and 'no sepsis' group. Blood samples were collected for CRP, IL-6 and IgM determination. A CRP value of 5 mg/l was the best among the three parameters with 95% sensitivity and 98% negative predictive value. Combination between parameters was helpful in enhancing the ability to diagnose sepsis. The best combination was CRP > or = 5 mg/l and/or IgM of > or =20 mg/dl. We conclude that CRP, IL-6 and IgM are helpful in the early diagnosis of Gram-negative neonatal sepsis. However, CRP continues to be the best single test. The use of both CRP and IgM in combination was the most helpful in predicting Gram-negative neonatal sepsis. We speculate a significant role of this combination in making decisions regarding antibiotics treatment and upgrading the level of medical care and observation in a setting where Gram-negative micro-organisms are causing the majority of neonatal infections.

Knowledge, attitude and practice of breastfeeding in the north of Jordan: a cross-sectional study

BACKGROUND

In Jordan, as in neighboring countries in the Middle East, higher education and higher employment rates in recent years among women have had an impact on traditionally based infant feeding. The objective of this study was to evaluate practice, knowledge and attitude to breastfeeding and to assess factors associated with breastfeeding among women in the north of Jordan.

METHODS

A cross sectional study was carried out between 15 July 2003 and 15 August 2003. A total of 344 women with children aged between 6 months and 3 years from five different villages in the north of Jordan were randomly selected and interviewed. Information regarding participants' demographics, infant feeding in first six months of life, knowledge and attitude towards breastfeeding was collected.

RESULTS

Full breastfeeding was reported by 58.3%, mixed feeding was reported by 30.3% and infant formula feeding was reported by 11.4%. Almost one third of the full breastfeeding group did so for 6-12 months, and almost two thirds did continue breastfeeding for more than one year. Employed women were more likely not to practice full breastfeeding compared to unemployed women (odds ratio 3.34, 95% CI 1.60, .98), and women who had cesarian delivery were more likely not to practice full breastfeeding compared to those who had vaginal delivery (odds ratio 2.36, 95% CI 1.17, 4.78). Jordanian women had a positive attitude but work place and short maternity leaves had a negative impact on breastfeeding.

CONCLUSION

This study showed that a high proportion of Jordanian women did breastfeed for more than one year. However, working women and those who deliver by caesarean section were less likely to breastfeed. It is speculated that adopting facilitatory measures at hospitals and work place could increase the rate of full breastfeeding.
