Light-emitting diode phototherapy for unconjugated hyperbilirubinaemia in neonates

Home phototherapy for neonatal hyperbilirubinemia: current practices and attitudes

BACKGROUND

Neonatal hyperbilirubinemia is a leading cause of hospitalization during the first week of life. Recent research suggest that phototherapy, the standard treatment, can be safely and effectively administered at home. Some Dutch hospitals have already adopted home-based phototherapy. The TREAT Jaundice@home study aims to contribute to its broader implementation across the Netherlands. Understanding the perspectives, perceptions, and needs of healthcare professionals is essential for facilitating this implementation.

METHODS

This cross-sectional survey targeted pediatricians, midwives, and maternity care assistants with and without prior experience with phototherapy at home. The 82-item questionnaire covered respondent background, experience, interests, motivation, responsibilities, logistics, collaboration, knowledge, indications and contraindications, financial aspects, and implementation readiness.

RESULTS

The study included responses from 16 pediatricians, 90 community midwives, and 514 maternity care assistants. Findings indicate a positive reception of phototherapy at home, regardless of prior experience. The majority expressed satisfaction, recognized potential benefits, and/or demonstrated a willingness to adopt this innovation. Key challenges identified include the need for information, the lack of guidelines, coordination and collaboration issues, and concerns about financial compensation.

DISCUSSION

Phototherapy at home is well-received by healthcare professionals. Addressing the identified challenges is imperative for successful implementation, ultimately benefiting neonates, their families, and healthcare systems.

IMPACT

Phototherapy at home is well-received and perceived as beneficial by healthcare professionals with and without prior experience Key challenges include the need for better knowledge and guidelines, coordination and collaboration issues among healthcare professionals, and concerns about financial compensation Addressing these challenges through comprehensive information, standardized protocols, improved collaboration, and adequate financial compensation is essential to successfully implement phototherapy at home on a larger scale.

Risk of childhood neoplasms related to neonatal phototherapy- a systematic review and meta-analysis

CONTEXT

Observational studies have shown conflicting results as to whether exposure to neonatal phototherapy is associated with increased rates of childhood cancer.

OBJECTIVE

To describe the rates of childhood neoplasms and cancer after neonatal phototherapy.

DATA SOURCES

The CENTRAL, PubMed, Scopus, and Web of Science databases.

STUDY SELECTION

Observational studies regardless of design were included.

DATA EXTRACTION

The data were extracted by one author and validated by another. The risk-of-bias assessment was performed using the ROBINS-E and Joanna Briggs Institute critical appraisal tools.

RESULTS

Six cohort and 10 case-control studies were included. The overall risk of bias was high in seven and low in nine studies. In cohort studies, the odds ratio (OR) was increased for hematopoietic cancer (1.44; confidence interval [CI]: 1.16-1.80) and solid tumors (OR: 1.18; CI: 1.00-1.40). In case-control studies, the OR was 1.63 (CI: 0.99-2.67) for hematopoietic cancers and 1.18 (CI: 1.04-1.34) for solid tumors.

CONCLUSIONS

Children with a history of neonatal phototherapy had increased risk of hematopoietic cancer and solid tumors. The evidence quality was limited due to the high risk of bias and potential residual confounding.

IMPACT STATEMENT

Exposure to neonatal phototherapy increased later risk of hematopoietic cancer and solid tumors. This is the most comprehensive study on the association between phototherapy and cancer, but the evidence quality was limited due risk of bias and residual confounding. Future large scale well conducted studies are still needed to better estimate the association and.

Continuous versus intermittent phototherapy in treatment of neonatal jaundice: a randomized controlled trial

Phototherapy (PT) is a widely used treatment for neonatal jaundice, yet the ideal model of application remains controversial. In this study, the effects of continuous phototherapy (CPT) and intermittent phototherapy (IPT) models were compared in the treatment of neonatal indirect hyperbilirubinemia (IHB) and whether IPT is a superior modality is investigated. Single-centre parallel randomized controlled open label trial. A computer-based table of random numbers was used to allocate treatments. Newborns ≥ 34 weeks' gestation who received phototherapy in our neonatal intensive care unit (NICU) between July 2022 and April 2023 were included. CPT was applied continuously for 6 h, and IPT was applied as 2 cycles of 1 h on and 2 h off in a 6-h session. Rebound TSB was measured 8 h after phototherapy was stopped in both groups. Phototherapy duration, TSB reduction rate and rebound bilirubin rate were compared between intervention groups. One hundered and four neonates met the inclusion criteria during the study period. CPT and IPT were each used in 52 newborns. Demographic characteristics of the study groups, including sex, mode of delivery, birth weight, admission weight, age at postnatal presentation, diet, discharge weight, and history of PT in siblings, were similar (p > 0.05). The most common cause of IHB in both groups was ABO incompatibility. The median phototherapy time was 12 h (6-15) in the CPT group and 4 h (2-4) in the IPT group (p < 0.001). The mean rate of bilirubin decrease was 1.12 ± 0.73 mg/dl/h in those who underwent IPT and 0.51 ± 0.33 mg/dl/h in those who underwent CPT (p < 0.001). The mean rebound bilirubin rate 8 h after phototherapy was 0.08 ± 0.28 mg/dl/h in the CPT group, and -0.01 ± 0.17 mg/dl/h in the IPT group (p = 0.039). The length of hospital stay was longer in the CPT group (p = 0.032). Skin rash, diarrhoea and increased body temperature were less frequent in the IPT group (p < 0.001).

CONCLUSIONS

In this study, IPT was found to be at least as effective as CPT in reducing total serum bilirubin. Even though the duration of PT is shorter in IPT, the slower rate of rebound bilirubin, shorter hospital stays and lower incidence of side effects indicated that intermittent phototherapy is superior to continuous phototherapy. Choosing IPT over CPT is a more rational approach in neonatal jaundice.

CLINICALTRIALS

gov Identifier: NCT06386731 (registered retrospectively on 23/04/2024) What is Known: • PT is common used in the treatment of neonatal jaundice. • There is no standard model of application for PT.

WHAT IS NEW

• The IPT model is as effective as CPT. • Newborns are discharged faster with IPT.

Innovative approaches to neonatal jaundice diagnosis and management in low-resourced settings

Persistent challenges in addressing severe neonatal hyperbilirubinaemia in resource-constrained settings have led to ongoing and often unacceptable rates of morbidity, disability and mortality. These challenges stem from limitations such as inadequate, inefficient or financially inaccessible diagnostic and therapeutic options. However, over the past decade, noteworthy innovations have emerged to address some of these hurdles, and these innovations are increasingly poised for broader implementation. This review provides a concise summary of these novel, economically viable diagnostic solutions, encompassing point-of-care assays and smartphone applications, as well as treatment modalities, notably more effective phototherapy and filtered sunlight. These advancements hold promise and have the potential to meaningfully reduce the burden of neonatal hyperbilirubinaemia, signifying a promising shift in the landscape of neonatal healthcare.

Discharge of newborns with risk factors of severe hyperbilirubinemia: description of a hospital at home-based care monitoring and phototherapy

Neonatal jaundice is common and associated with delay in hospital discharge and risk of neurological sequelae if not treated. The objectives of the study were to report on our experience of the monitoring and treatment of neonatal jaundice in a home care setting and its feasibility and safety for neonates with high risk of severe hyperbilirubinemia. The 2-year study has been led in the greater Paris University Hospital At Home (Assistance Publique-Hôpitaux de Paris). The device of the intervention was the Bilicocoon® Bag, a light-emitting diode sleeping bag worn by the neonate when the total serum bilirubin value exceeds intensive phototherapy threshold, according to the guidelines from the American Academy of Pediatrics. One hundred and thirty-nine neonates had participated in the intervention and 39 (28%) were treated by phototherapy at home, as continuation of inpatient phototherapy or started at home. Seventy-five percent of the sample had more than two risk factors for development of severe hyperbilirubinemia. Twenty five percent of the cohort who received phototherapy at home had lower gestational age (p < 0.014) and had younger age at discharge from maternity (p < 0.09). Median length of stay in hospital at home was 5 days. Two patients needed readmission in conventional hospital (1%) for less than 24 h. In multivariate model, the length of stay decreased with the higher gestational age (p < 0.001) and increased significantly with the older age at discharge, the birth weight < 10th percentile, and a treatment by phototherapy at home.    Conclusion: Hospital at home, which is a whole strategy using an effective and convenient phototherapy device combined with a specialized medical follow-up, could be an alternative to conventional hospitalization for neonates at high risk of severe jaundice. The maternity discharge is facilitated, the mother-infant bonding can be promoted, and the risk of conventional rehospitalization is minimal, while guaranteeing the safety of this specific care. What is Known: • Managing neonatal jaundice is provided in conventional hospital with phototherapy. • Neonatal jaundice increases the risk of prolonged hospitalization or readmission. What is New: • Phototherapy is feasible in hospital at home for neonates with high risk of severe hyperbilirubinemia. • The care pathway of neonates from conventional hospital to hospital at home is described.

Biphasic Effects of Blue Light Irradiation on Human Umbilical Vein Endothelial Cells

Blue light regulates biological function in various cells, such as proliferation, oxidative stress, and cell death. We employed blue light illumination on human umbilical vein endothelial cells utilizing a LED device at 453 nm wavelength and revealed a novel biphasic response on human umbilical vein endothelial cells (HUVECs). The results showed that low fluence blue light irradiation promoted the fundamental cell activities, including cell viability, migration and angiogenesis by activating the angiogenic pathways such as the VEGF signaling pathway. In contrast, high fluence illumination caused the opposite effect on those activities by upregulating pro-apoptotic signaling cascades like ferroptosis, necroptosis and the p53 signaling pathways. Our results provide an underlying insight into photobiomodulation by blue light and may help to implement potential treatment strategies for treating angiogenesis-dependent diseases.

Neonatal hyperbilirubinemia management: Clinical assessment of bilirubin production

The predominant cause of elevated total/plasma bilirubin (TB) levels is from an increase in bilirubin production primarily because of ongoing hemolysis. If undiagnosed or untreated, the risk for developing extreme neonatal hyperbilirubinemia and possibly bilirubin-induced neurological dysfunction (BIND) is increased. Since carbon monoxide (CO) and bilirubin are produced in equimolar amounts during the heme catabolic process, measurements of end-tidal CO levels, corrected for ambient CO (ETCOc) can be used as a direct indicator of ongoing hemolysis. A newly developed point-of-care ETCOc device has been shown to be a useful for identifying hemolysis-associated hyperbilirubinemia in newborns. This review summarizes the biology of bilirubin production, the clinical utility of a novel device to identify neonates undergoing hemolysis, and a brief introduction on the use of ETCOc measurements in a cohort of neonates in China.

Improving Effectiveness of Phototherapy in an Academic Center: A Quality Improvement Project

Neonatal hyperbilirubinemia is a common cause of delayed discharge and readmissions in our institution. As previously published, the irradiance our phototherapy (PT) units provided was below the irradiance recommended by the AAP for intensive phototherapy (>30 µW/cm²/nm). We measured irradiance delivered by our PT units (Drager 4000) using a standardized footprint grid. By varying number of blue and white fluorescent PT lights, height of PT unit above the neonate and type of bed used (open bassinet versus isolette), we determined the optimal PT arrangement needed to deliver intensive PT (30 µW/cm²/nm). We then developed a standardized, multidisciplinary protocol specifying light arrangement and distance required needed to achieve the desired irradiance level. We were able to show improved irradiance following above changes. Onsite measurement of irradiance provided by local phototherapy units and development of a multidisciplinary, standardized protocol are necessary to assure delivery of recommended levels PT for neonates with hyperbilirubinemia.

An evaluation of phototherapy device performance in a tertiary health facility

INTRODUCTION

A range of phototherapy devices are commercially available. The American Academy of Pediatrics (2004) recommends routine intensity measurement of phototherapy devices to ensure that babies affected by hyperbilirubinemia receive effective phototherapy.

OBJECTIVE

The aims of this study were to calculate the irradiance decay velocity of phototherapy devices used in a tertiary care hospital to evaluate whether current maintenance procedures for phototherapy devices are effective, and to contribute to the improvement of a standardized maintenance procedure in daily practice, thus helping to ensure that all babies affected by hyperbilirubinemia receive prompt treatment.

METHODS

This research represents a prospective observational study conducted at Dr. Soetomo Academic Teaching Hospital in Surabaya, Indonesia from February 2019-July 2019. The intensities of 11 phototherapy devices were measured at specific times using a Bili Blanket Meter II. We calculated the Δ irradiance differences in μW/cm2/nm and calculated them as velocity μW/cm2/nm/hour of use.

RESULTS

Among the 11 phototherapy devices included in this study, nine were fluorescent and two were light-emitting diode (LED) machines. The mean (standard deviation) irradiance decay velocity of the fluorescent lamps was 0.02 (±0.03) μW/cm2/nm/hour of use, while that of the LED lamps was 0.015 (±0.007) μW/cm2/nm/hour of use. The fastest irradiance decay velocity was 0.08 μW/cm2/nm/hour of use, while the slowest irradiance decay velocity was <0.01 μW/cm2/nm/hour of use, both of which were from fluorescent-based devices. There was one fluorescent-based device that provided an intensity lower than the therapeutic level.

CONCLUSION

Irradiance decay occurred in all phototherapy device lamps. It is important to perform routinely intensity measurements, regardless of manufacturer recommendations, to avoid ineffective phototherapy resulting from intensities lower than the required therapeutic levels.

Use of reflective materials during phototherapy for newborn infants with unconjugated hyperbilirubinaemia

BACKGROUND

Phototherapy is a well-established effective therapy for treating babies with significant neonatal jaundice. Studies have shown that increasing light intensity will increase its efficiency. A potentially inexpensive and easy way of increasing the intensity of light on the body of the infant may be to hang reflective materials from the sides of phototherapy units.

OBJECTIVES

To assess the effects of reflective materials in combination with phototherapy compared with phototherapy alone for unconjugated hyperbilirubinaemia in neonates.

SEARCH METHODS

We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 11), in the Cochrane Library; Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions(R); and the Cumulative Index of Nursing and Allied Health Literature (CINAHL), on 1 November 2019. We also searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials if the participants, who were term or preterm infants, received phototherapy with curtains made of reflective materials of any type in the treatment arm, and if those in the comparison arm received similar phototherapy without curtains or other intensified phototherapy, such as a double bank of lights.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. We used the GRADE approach to assess the certainty of evidence.

MAIN RESULTS

Of 15 studies identified, we included 12 (1288 babies) in the review - 11 comparing phototherapy with reflective materials and phototherapy alone, and one comparing a single phototherapy light bank with reflective materials with double phototherapy. All reflective materials consisted of curtains on three or four sides of the cot and were made of white plastic (five studies), white linen (two studies), or aluminium (three studies); materials were not specified in two studies. Only 11 studies (10 comparing reflective materials versus none and one comparing reflective curtains and a single bank of lights with a double (above and below) phototherapy unit) provided sufficient data to be included in the meta-analysis. Two excluded studies used the reflective materials in a way that did not meet our inclusion criteria, and we excluded one study because it compared four different phototherapy interventions not including reflective materials. The risk of bias of included studies was generally low, but all studies had high risk of performance bias due to lack of blinding of the intervention. Three studies (281 participants) reported a decline in serum bilirubin (SB) (μmol/L) at four to eight hours (mean difference (MD) -14.61, 95% confidence interval (CI) -19.80 to -9.42; I² = 57%; moderate-certainty evidence). Nine studies (893 participants) reported a decline in SB over 24 hours and showed a faster decline in SB in the intervention group, but heterogeneity (I² = 97%) was too substantial to permit a meaningful estimate of the actual effect size (very low-certainty evidence). Subgroup analysis by type of reflective material used did not explain the heterogeneity. Exchange transfusion was reported by two studies; both reported none in either group. Four studies (466 participants) reported the mean duration of phototherapy, and in each of these studies, it was reduced in the intervention group but there was substantial heterogeneity (I² = 88%), precluding meaningful meta-analysis of data. The only two studies that reported the mean duration of hospital stay in hours showed a meaningful reduction (MD -41.08, 95% CI -45.92 to -36.25; I² = 0; moderate-certainty evidence). No studies reported costs of the intervention, parental or medical staff satisfaction, breastfeeding outcomes, or neurodevelopmental follow-up. The only study that compared use of curtains with double phototherapy reported similar results for both groups. Studies that monitored adverse events did not report increased adverse events related to the use of curtains, including acute life-threatening events, but other rarer side effects could not be excluded.

AUTHORS' CONCLUSIONS

Moderate-certainty evidence shows that the use of reflective curtains during phototherapy may result in greater decline in SB. Very low-certainty evidence suggests that the duration of phototherapy is reduced, and moderate-certainty evidence shows that the duration of hospital stay is also reduced. Available evidence does not show any increase in adverse events, but further studies are needed.

Comparing the effect of kangaroo mother care and field massage on serum bilirubin level of term neonates with hyperbilirubinemia under phototherapy in the neonatal ward

Background:

Several factors contribute to the effectiveness of phototherapy. The aim of this study was to compare the effect of kangaroo mother care (KMC) and field massage on bilirubin level of term neonates with hyperbilirubinemia under phototherapy in the neonatal ward.

Methods:

This double-blind clinical trial was performed on 90 term neonates aged 48 hours with hyperbilirubinemia, hospitalized in Fereydunkenar Hospital during 2018-2019. The infants were randomly divided into 3 groups of massage with phototherapy, KMC with phototherapy and control (received conventional phototherapy without KMC and massage). The massage group used field technique for three 15-minutes in 3 days and the KMC group received KMC for five 30 minutes in 3 days as well. In three groups, the serum bilirubin levels were compared at baseline, 24, 48, 72 hours after the onset and at the end of phototherapy. Moreover, the mean duration of phototherapy and hospitalization was compared during the treatment.

Results:

Serum bilirubin levels at baseline in the control, field massage and KMC groups were (17±1.38, 17.01±1.46 and 16.97±1.27mg/dl) and at the end of phototherapy were (6.97±0.47, 5.56±0.48 and 5.91±0.52 mg/dl) respectively. There was a significant difference between the intervention and control groups (p<0.001). The mean duration of phototherapy and hospitalization had no significant difference between two intervention groups (p>0.001), but it was significantly higher in control group than intervention groups (p<0.001).

Conclusion:

The use of massage or KMC with phototherapy, compared to the phototherapy alone, can reduce the bilirubin level, phototherapy duration and hospital stay.

A randomized control trial of phototherapy and 20% albumin versus phototherapy and saline in Kilifi, Kenya

Objective

The study evaluated the efficacy of phototherapy and 20% albumin infusion to reduce total serum bilirubin (TSB) in neonates with severe hyperbilirubinemia. The primary outcome was a reduction of TSB at the end of treatment. The secondary outcomes were the need for exchange transfusion, inpatient mortality, neurological outcomes at discharge, and development outcomes at 12-months follow-up.

Results

One hundred and eighteen neonates were randomly assigned to phototherapy and 20% albumin (n = 59) and phototherapy and saline (n = 69). The median age at admission was 5 (interquartile range (IQR) 3–6) days, and the median gestation was 36 (IQR 36–38) weeks. No significant differences were found in the change in TSB (Mann–Whitney U =609, p = 0.98) and rate of change in TSB per hour after treatment (Mann–Whitney U = 540, p = 0.39) between the two groups. There were no significant differences between the two groups in the proportion of participants who required exchange transfusion (χ² (2) = 0.36, p = 0.546); repeat phototherapy (χ² (2) = 2.37, p = 0.123); and those who died (χ² (2) = 0.92, p = 0.337). Trial registration The trial was registered in the International Standardized Randomized Controlled Trial Number (ISRCTN); trial registration number ISRCTN89732754.

New high intensity fibreoptic phototherapy devices in healthy newborns: a single pad wrapped around the neonate body in comparison with a double pad device

Background

Fibreoptic Phototherapy (FPT) allows to lower total serum bilirubin (TSB) levels in healthy neonates maintained in rooming-in with their mothers. The 2004 Cochrane review showed that, differently from preterm neonates, FPT was not as effective as traditional phototherapy in term neonates (TN), unless the simultaneous utilization of two FPT devices. Aim of this study was to compare the efficacy of two FPT devices, both equipped with a single light-emitting diode (LED): the first one has a single large pad wrapped around the infant body (Bilisoft, GE Health Care) (device A), the second one is a double-pad phototherapy device (BiliCocoon, CremascolieIris) (device B).

Methods

We studied 172 healthy neonates with non-hemolytic hyperbilirubinaemia: 57 TN and 57 late preterm neonates (LPN) treated with device A (Group 1); 47 TN and 11 LPN treated with device B (Group 2). We evaluated the differences between groups by the Student’s t-test for continuous variables and by chi square test for categorical data. A two tailed p < 0.05 was considered significant.

Results

There were no differences in term of duration of FPT, TSB hourly reduction, percentage of TSB reduction after FPT, TSB maximum rebound, percentage of TSB increase after FPT discontinuation and number of after-discharge checks. Two neonates treated with device B showed no decrease in TSB values during FPT. Seven infants treated with device B experienced hyperpyrexia.

Conclusions

The two LED FPT devices were both effective in lowering TSB either in TN or LPN. Device A was effective in all treated neonates without negative side effects during treatment; device B was effective in all but 2 infants and 12% of the neonates in the same group experienced hyperpyrexia. According to our results, the single big pad wrapped around the infant body has the same efficacy as a double FPT device in TN and LPN.

Screening and treatment to reduce severe hyperbilirubinaemia in infants in primary care (STARSHIP): a factorial stepped-wedge cluster randomised controlled trial protocol

INTRODUCTION

Jaundice caused by hyperbilirubinaemia is a physiological phenomenon in the neonatal period. However, severe hyperbilirubinaemia, when left untreated, may cause kernicterus, a severe condition resulting in lifelong neurological disabilities. Although commonly applied, visual inspection is ineffective in identifying severe hyperbilirubinaemia. We aim to investigate whether among babies cared for in primary care: (1) transcutaneous bilirubin (TcB) screening can help reduce severe hyperbilirubinaemia and (2) primary care-based (versus hospital-based) phototherapy can help reduce hospital admissions.

METHODS AND ANALYSIS

A factorial stepped-wedge cluster randomised controlled trial will be conducted in seven Dutch primary care birth centres (PCBC). Neonates born after 35 weeks of gestation and cared for at a participating PCBC for at least 2 days within the first week of life are eligible, provided they have not received phototherapy before. According to the stepped-wedge design, following a phase of 'usual care' (visual assessment and selective total serum bilirubin (TSB) quantification), either daily TcB measurement or, if indicated, phototherapy in the PCBC will be implemented (phase II). In phase III, both interventions will be evaluated in each PCBC. We aim to include 5500 neonates over 3 years.Primary outcomes are assessed at 14 days of life: (1) the proportion of neonates having experienced severe hyperbilirubinaemia (for the TcB screening intervention), defined as a TSB above the mean of the phototherapy and the exchange transfusion threshold and (2) the proportion of neonates having required hospital admission for hyperbilirubinaemia treatment (for the phototherapy intervention in primary care).

ETHICS AND DISSEMINATION

This study has been approved by the Medical Research Ethics Committee of the Erasmus MC Rotterdam, the Netherlands (MEC-2017-473). Written parental informed consent will be obtained. Results from this study will be published in peer-reviewed journals and presented at (inter)national meetings.

Light Emitting Diode (LED) Phototherapy versus Conventional Phototherapy in Neonatal Hyperbilirubinemia: A Single Blinded Randomized Control Trial from Coastal India

Neonatal hyperbilirubinemia is a common problem with potentiality to cause irreversible brain damage. Reduction of serum bilirubin level is essential to minimize such damage. Compact fluorescent tubes, halogen bulbs, fiber optic blankets, and LEDs are commonly used light sources for phototherapy with varying efficacies. This study aimed at evaluating the effect of LED versus conventional phototherapy on (a) rate of reduction in total serum bilirubin levels, (b) effect on urinary lumirubin excretion, and (c) comparing side effects of phototherapies among neonates with hyperbilirubinemia. In this randomized control trial, 166 neonates ≥ 35 weeks of age requiring phototherapy were recruited and further divided into 2 groups [LED (83) and conventional (83)] by using computer generated random numbers. Serial total serum bilirubin levels and random urinary lumirubin levels were collected and side effects of phototherapy were noted. Rate of fall in total serum bilirubin levels (TSB, μmol/L/hour) and random urinary lumirubin levels were computed. Data were collected using a pretested proforma. Analysis was done with Statistical Package for Social Sciences (SPSS) version 11.5. Independent sample “t” test and Chi-square tests were used with p value of <0.05 being significant. Significant difference was documented in mean rate of decrease of TSB (μmol/L/hour) in LED group (5.3 ± 2.91) when compared to conventional group (3.76 ± 2.39) (p <0.001). A significant increase in mean random urinary lumirubin levels (arbitrary units) was observed in LED group (129.01 ± 33.18) when compared to conventional group (114.44 ± 44.84) (p = 0.021). Side effects were minimal and comparable in both groups. This study concludes the rates of decrease in total serum bilirubin levels and increase in urinary lumirubin levels were significant with LED when compared with conventional phototherapy, implying LED to be more efficacious.

A Novel Non-invasive Technique of Measuring Bilirubin Levels Using BiliCapture

OBJECTIVES

In preterm infants, hyperbilirubinemia is common and can impair the central nervous system. The tests available for measuring bilirubin is to collect blood from heel pricking and occasionally taking blood samples from inserted cannulas, which is painful. Therefore, there is a need to develop a non-invasive device to detect bilirubin levels in newborns and interpret the severity of jaundice.

METHODS

We conducted a cross-sectional study of 100 neonates. Patient data was collected between June 2015 and December 2016 from King Khalid Hospital at Al-Majma'ah, Saudi Arabia, and Alpine Hospital, Gurgaon, India. The mean gestational age of neonates was 39.0 weeks. Total bilirubin was measured using a transcutaneous bilirubinometer on the forehead and obtaining optical imaging through scanning of conjunctiva of eyes, also referred to as BiliChek and BiliCapture, respectively. Later the blood samples were obtained from these patients and tested in the laboratory to determine total serum bilirubin (TSB) levels.

RESULTS

The concentration of bilirubin as measured from serum, BiliChek, and BiliCapture were 10.7±2.0, 11.6±2.7, and 13.1±2.3 mg/dL, respectively. Correlation was high between TSB and BiliChek (r2 = 0.88) and between TSB and BiliCapture (r2 = 0.73). The Bland-Altman plots showed good agreement when comparing bilirubin values for both BiliChek and BiliCapture devices. Bilirubin measurement was further checked for the sensitivity and specificity and was 88.0% and 76.0% using BiliChek and 92.0% and 75.6% using BiliCapture, respectively.

CONCLUSIONS

The optical imaging of conjunctiva for bilirubin assay is a safe alternative to a laboratory bilirubin assay and transcutaneous bilirubinometer BiliChek.

A comparison of the effectiveness of three LED phototherapy machines, single- and double-sided, for treating neonatal jaundice in a low resource setting

INTRODUCTION

Neonatal jaundice is one of the most common reasons for hospital admission in low resource settings. Treatment is frequently inadequate as conventional phototherapy requires frequent bulb changes. LED phototherapy has comparable efficacy to conventional phototherapy, and the bulbs last over 40,000 hours. This observational study compares the effectiveness of three LED machines, two single-sided and one double-sided in routine use in Vietnam.

METHODS

We included all infants weighting ≥1500g and with jaundice diagnosed visually or by Total Serum Bilirubin (TSB) measurement at The Da Nang Hospital for Women and Children (Da Nang, Vietnam). The primary endpoint was the average hourly change in TSB over the first six hours of treatment. The secondary endpoints were duration of treatment; average hourly change in TSB over treatment, and length of stay in the neonatal unit. Multivariable analysis and bootstrap methods was performed to compare outcomes, adjusting for potential confounders.

RESULTS

All outcomes were comparable in the two single-sided machines. The double-sided machine showed 54% increase in the hourly speed of TSB reduction (1.3 μmol/L/hr, 95% CI 0.3-2.3), with a 45% increase in the speed of TSB reduction over the duration of treatment (0.9 μmol/L/hr, 95% CI 0.6-1.3). In addition, the double-sided machine was associated with 21% reduction in the duration of treatment (14 hours, 95% CI 5-22) and 16% reduction of length of stay (14 hours, 95% CI 3-25).

CONCLUSION

The results confirm and quantify the benefits of increasing surface-area exposure during phototherapy. Adjusted for multiple potential confounders, use of double-sided phototherapy can substantially increase the speed of TSB reduction, and substantially decrease the duration of treatment and length of stay in the NCU.

Phototherapy and its effect on some physiological functions in newborns

Phototherapy represents the most common therapeutic intervention at neonatology departments in the first days of life. The beneficial effects of light on the decrease of the serum bilirubin level were first described by Cremer et al. in 1950’s (1). Since then phototherapy has been successfully used to treat severe hyperbilirubinaemia and has almost completely replaced exchange transfusion. Phototherapy is a relatively non-invasive method. However, along with decreasing bilirubin level, it can also influence some other functions: perfusion of organs, predominantly skin; peripheral vascular resistance; distribution of blood flow; heart activity and, thus, also systemic blood pressure along with breathing. A side component of applied light is a certain amount of heat which warms the body surface up and, therefore, the risk of exogenous overheating and increased water loss through the skin arise. Maternal-infant separation, modification of calcium homeostasis, disturbed circadian rhythm, or changes of the hemodynamics of various organ systems are only a few of the undesired effects which prove phototherapy not to be a treatment without any side effects. Careful indication of phototherapy is essential, particularly in premature infants.

Service readiness for inpatient care of small and sick newborns: what do we need and what can we measure now?

BACKGROUND

Each year an estimated 2.6 million newborns die, mainly from complications of prematurity, neonatal infections, and intrapartum events. Reducing these deaths requires high coverage of good quality care at birth, and inpatient care for small and sick newborns. In low- and middle-income countries, standardised measurement of the readiness of facilities to provide emergency obstetric care has improved tracking of readiness to provide care at birth in recent years. However, the focus has been mainly on obstetric care; service readiness for providing inpatient care of small and sick newborns is still not consistently measured or tracked.

METHODS

We reviewed existing international guidelines and resources to create a matrix of the structural characteristics (infrastructure, equipment, drugs, providers and guidelines) for service readiness to deliver a package of inpatient care interventions for small and sick newborns. To identify gaps in existing measurement systems, we reviewed three multi-country health facility survey tools (the Service Availability and Readiness Assessment, the Service Provision Assessment and the Emergency Obstetric and Newborn Care Assessment) against our service readiness matrix.

FINDINGS

For service readiness to provide inpatient care for small and sick newborns, our matrix detailed over 600 structural characteristics. Our review of the SPA, the SARA and the EmONC assessment tools identified several measurement omissions to capture information on key intervention areas, such as thermoregulation, feeding and respiratory support, treatment of specific complications (seizures, jaundice), and screening and follow up services, as well as specialised staff and service infrastructure.

CONCLUSIONS

Our review delineates the required inputs to ensure readiness to provide inpatient care for small and sick newborns. Based on these findings, we detail where questions need to be added to existing tools and describe how measurement systems can be adapted to reflect small and sick newborns interventions. Such work can inform investments in health systems to end preventable newborn death and disability as part of the Every Newborn Action Plan.

The Turkish Neonatal Jaundice Online Registry: A national root cause analysis

Background

Neonatal jaundice (NNJ) is common, but few root cause analyses based on national quality registries have been performed. An online registry was established to estimate the incidence of NNJ in Turkey and to facilitate a root cause analysis of NNJ and its complications.

Methods

A multicenter prospective study was conducted on otherwise healthy newborns born at ≥35 weeks of gestation and hospitalized for only NNJ in 50 collaborator neonatal intensive care units across Turkey over a 1-year period. Patients were analyzed for their demographic and clinical characteristics, treatment options, and complications.

Results

Of the 5,620 patients enrolled, 361 (6.4%) had a bilirubin level ≥25 mg/dL on admission and 13 (0.23%) developed acute bilirubin encephalopathy. The leading cause of hospital admission was hemolytic jaundice, followed by dehydration related to a lack of proper feeding. Although all infants received phototherapy, 302 infants (5.4%) received intravenous immunoglobulin in addition to phototherapy and 132 (2.3%) required exchange transfusion. The infants who received exchange transfusion were more likely to experience hemolytic causes (60.6% vs. 28.1%) and a longer duration of phototherapy (58.5 ± 31.7 vs. 29.4 ± 18.8 h) compared to infants who were not transfused (p < 0.001). The incidence of short-term complications among discharged patients during follow-up was 8.5%; rehospitalization was the most frequent (58%), followed by jaundice for more than 2 weeks (39%), neurological abnormality (0.35%), and hearing loss (0.2%).

Conclusions

Severe NNJ and bilirubin encephalopathy are still problems in Turkey. Means of identifying at-risk newborns before discharge during routine postnatal care, such as bilirubin monitoring, blood group analysis, and lactation consultations, would reduce the frequency of short- and long-term complications of severe NNJ.

Fluid supplementation for neonatal unconjugated hyperbilirubinaemia

BACKGROUND

Neonatal hyperbilirubinaemia is a common problem which carries a risk of neurotoxicity. Certain infants who have hyperbilirubinaemia develop bilirubin encephalopathy and kernicterus which may lead to long-term disability. Phototherapy is currently the mainstay of treatment for neonatal hyperbilirubinaemia. Among the adjunctive measures to compliment the effects of phototherapy, fluid supplementation has been proposed to reduce serum bilirubin levels. The mechanism of action proposed includes direct dilutional effects of intravenous (IV) fluids, or enhancement of peristalsis to reduce enterohepatic circulation by oral fluid supplementation.

OBJECTIVES

To assess the risks and benefits of fluid supplementation compared to standard fluid management in term and preterm newborn infants with unconjugated hyperbilirubinaemia who require phototherapy.

SEARCH METHODS

We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 5), MEDLINE via PubMed (1966 to 7 June 2017), Embase (1980 to 7 June 2017), and CINAHL (1982 to 7 June 2017). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials.

SELECTION CRITERIA

We included randomised controlled trials that compared fluid supplementation against no fluid supplementation, or one form of fluid supplementation against another.

DATA COLLECTION AND ANALYSIS

We extracted data using the standard methods of the Cochrane Neonatal Review Group using the Covidence platform. Two review authors independently assessed the eligibility and risk of bias of the retrieved records. We expressed our results using mean difference (MD), risk difference (RD), and risk ratio (RR) with 95% confidence intervals (CIs).

MAIN RESULTS

Out of 1449 articles screened, seven studies were included. Three articles were awaiting classification, among them, two completed trials identified from the trial registry appeared to be unpublished so far.There were two major comparisons: IV fluid supplementation versus no fluid supplementation (six studies) and IV fluid supplementation versus oral fluid supplementation (one study). A total of 494 term, healthy newborn infants with unconjugated hyperbilirubinaemia were evaluated. All studies were at high risk of bias for blinding of care personnel, five studies had unclear risk of bias for blinding of outcome assessors, and most studies had unclear risk of bias in allocation concealment. There was low- to moderate-quality evidence for all major outcomes.In the comparison between IV fluid supplementation and no supplementation, no infant in either group developed bilirubin encephalopathy in the one study that reported this outcome. Serum bilirubin was lower at four hours postintervention for infants who received IV fluid supplementation (MD -34.00 μmol/L (-1.99 mg/dL), 95% CI -52.29 (3.06) to -15.71 (0.92); participants = 67, study = 1) (low quality of evidence, downgraded one level for indirectness and one level for suspected publication bias). Beyond eight hours postintervention, serum bilirubin was similar between the two groups. Duration of phototherapy was significantly shorter for fluid-supplemented infants, but the estimate was affected by heterogeneity which was not clearly explained (MD -10.70 hours, 95% CI -15.55 to -5.85; participants = 218; studies = 3; I² = 67%). Fluid-supplemented infants were less likely to require exchange transfusion (RR 0.39, 95% CI 0.21 to 0.71; RD -0.01, 95% CI -0.04 to 0.02; participants = 462; studies = 6; I² = 72%) (low quality of evidence, downgraded one level due to inconsistency, and another level due to suspected publication bias), and the estimate was similarly affected by unexplained heterogeneity. The frequencies of breastfeeding were similar between the fluid-supplemented and non-supplemented infants in days one to three based on one study (estimate on day three: MD 0.90 feeds, 95% CI -0.40 to 2.20; participants = 60) (moderate quality of evidence, downgraded one level for imprecision).One study contributed to all outcome data in the comparison of IV versus oral fluid supplementation. In this comparison, no infant in either group developed abnormal neurological signs. Serum bilirubin, as well as the rate of change of serum bilirubin, were similar between the two groups at four hours after phototherapy (serum bilirubin: MD 11.00 μmol/L (0.64 mg/dL), 95% CI -21.58 (-1.26) to 43.58 (2.55); rate of change of serum bilirubin: MD 0.80 μmol/L/hour (0.05 mg/dL/hour), 95% CI -2.55 (-0.15) to 4.15 (0.24); participants = 54 in both outcomes) (moderate quality of evidence for both outcomes, downgraded one level for indirectness). The number of infants who required exchange transfusion was similar between the two groups (RR 1.60, 95% CI 0.60 to 4.27; RD 0.11, 95% CI -0.12 to 0.34; participants = 54). No infant in either group developed adverse effects including vomiting or abdominal distension.

AUTHORS' CONCLUSIONS

There is no evidence that IV fluid supplementation affects important clinical outcomes such as bilirubin encephalopathy, kernicterus, or cerebral palsy in healthy, term newborn infants with unconjugated hyperbilirubinaemia requiring phototherapy. In this review, no infant developed these bilirubin-associated clinical complications. Low- to moderate-quality evidence shows that there are differences in total serum bilirubin levels between fluid-supplemented and control groups at some time points but not at others, the clinical significance of which is uncertain. There is no evidence of a difference between the effectiveness of IV and oral fluid supplementations in reducing serum bilirubin. Similarly, no infant developed adverse events or complications from fluid supplementation such as vomiting or abdominal distension. This suggests a need for future research to focus on different population groups with possibly higher baseline risks of bilirubin-related neurological complications, such as preterm or low birthweight infants, infants with haemolytic hyperbilirubinaemia, as well as infants with dehydration for comparison of different fluid supplementation regimen.

Irradiance levels of phototherapy devices: a national study in Dutch neonatal intensive care units

OBJECTIVE

The objective of this study is to determine whether irradiance levels of phototherapy (PT) devices in Dutch neonatal intensive care units (NICUs) increased between 2008 and 2013.

STUDY DESIGN

Irradiance of all types of PT devices, used in combination with incubators, was measured with a Dale 40 Radiometer (Fluke Biomedical, Everett, WA, USA) in all 10 Dutch NICUs.

RESULTS

Irradiance increased in seven NICUs. Median (range) irradiance increased from 9.7 (4.3-32.6) to 16.4 (6.8-41) μW cm^-2 nm^-1 for 24 overhead devices (P=0.004) and from 6.8 (0.8-15.6) to 22.3 (1.1-36.3) μW cm^-2 nm^-1 for 12 underneath devices (P=0.014). Five light-emitting diode (LED)-based devices were used in 2013 and one in 2008. The mean distance between overhead PT device and infant decreased by ~9 cm (P<0.001). Significantly more devices delivered minimal (10 μW cm^-2 nm^-1) recommended irradiance levels (80 vs ~45%; P=0.002).

CONCLUSION

Irradiance of PT devices still varies, but has markedly improved since 2008 due to shorter distances between PT device and infant, and introduction of better performing LED-based devices.

Heating of Newborn Infants due to Blue Light-Emitting Diode Fibreoptic Phototherapy Pads

BACKGROUND

Surface temperatures of fibreoptic phototherapy pads using a high intensity blue light-emitting diode (LED) light source have not been studied.

OBJECTIVES

The aim of this study was to measure the temperature of LED fibreoptic phototherapy pads during phototherapy in a bench-top study, and to determine temperature effects on babies during phototherapy.

METHODS

A commercially available LED fibreoptic phototherapy system was tested. In a bench-top setting, pad surface temperatures were measured before, during and after a 12-h period of phototherapy (10 different LED light box-pad combinations). A prospective, cohort study of well babies at >34 weeks' gestation receiving phototherapy was then conducted to determine changes in pad and body temperatures during a 90-min phototherapy period.

RESULTS

In the bench-top study, the mean (95% CI) pad temperature was 21.8°C (21.5-22.1) before lights, 27.0°C (26.5-27.5) after 12 h of lights, and 22.1°C (21.9-22.4) 8 h after turning off the lights (F = 366.1, p < 0.0005). The magnitude of change in pad temperature with phototherapy was linearly correlated with irradiance (r = 0.89, p < 0.0005). The pad plastic covering absorbed 13% of blue light from fibres. In the clinical study, the warmest pad temperature during phototherapy was 38.9°C. Axillary temperature increased by a mean (95% CI) of 0.3°C (0.1-0.5), p < 0.019, and exceeded 37.5°C in 4 babies.

CONCLUSIONS

LED fibreoptic phototherapy pads are heated by high-intensity blue light. The thermal environment and temperature of babies should be monitored closely during LED fibreoptic phototherapy. A temperature probe placed between the skin and the pad will not accurately reflect the core temperature during fibreoptic phototherapy.

Gene expression profiling reveals aryl hydrocarbon receptor as a possible target for photobiomodulation when using blue light

Photobiomodulation (PBM) with blue light induces a biphasic dose response curve in proliferation of immortalized human keratinocytes (HaCaT), with a maximum anti-proliferative effect reached with 30min (41.4 J/cm2). The aim of this study was to test the photobiomodulatory effect of 41.4 J/cm2 blue light irradiation on ROS production, apoptosis and gene expression at different time points after irradiation of HaCaT cells in vitro and assess its safety. ROS concentration was increased 30 min after irradiation. However, already 1 h after irradiation, cells were able to reduce ROS and balance the concentration to a normal level. The sudden increase in ROS did not damage the cells, which was demonstrated with FACS analysis where HaCaT cells did not show any sign of apoptosis after blue light irradiation. Furthermore, a time course could be seen in gene expression analysis after blue light, with an early response of stimulated genes already 1 h after blue light irradiation, leading to the discovery of the aryl hydrocarbon receptor as possible target for blue light irradiation.

High-intensity light-emitting diode vs fluorescent tubes for intensive phototherapy in neonates

BACKGROUND

Special blue fluorescent tubes are recommended by the American Academy of Pediatrics (AAP) as the most effective light source for lowering serum bilirubin. A high-intensity light-emitting diode ('super LED') could render intensive phototherapy more effective than the above conventional methods. This study compared the efficacy and safety of a high-intensity light-emitting diode bed vs conventional intensive phototherapy with triple fluorescent tube units as a rescue treatment for severe unconjugated neonatal hyperbilirubinaemia.

METHOD

This was a randomised, prospective trial. Two hundred jaundiced neonates ≥ 35 weeks gestation who met the criteria for intensive phototherapy as per AAP guidelines were randomly assigned to be treated either with triple fluorescent tube units (group 1, n = 100) or a super LED bed (group 2, n = 100). The outcome was the avoidance of exchange transfusion by successful control of hyperbilirubinaemia.

RESULTS

Statistically significant higher success rates of intensive phototherapy were achieved among neonates treated with super LED (group 2) than in those treated conventionally (group 1) (87% vs 64%, P = 0.003). Significantly higher 'bilirubin decline' rates were reported in both haemolytic and non-haemolytic subgroups treated with the super LED bed compared with a similar sub-population in the conventionally treated group. Comparable numbers of neonates in both groups developed rebound jaundice (8% vs 10% of groups 1 and 2, respectively). Side-effects were mild in both groups, but higher rates of hyperthermia (12% vs 0%, P = 0.03), dehydration (8% vs 2%, P = 0.26) and skin rash (39% vs 1%, P = 0.002) were reported in the fluorescent tubes-treated group compared with the LED group.

CONCLUSIONS

Super LED is a safe rescue treatment for severe neonatal hyperbilirubinaemia, and its implementation may reduce the need for exchange transfusion.

Management of late-preterm and term infants with hyperbilirubinaemia in resource-constrained settings

Hyperbilirubinaemia is a ubiquitous transitional morbidity in the vast majority of newborns and a leading cause of hospitalisation in the first week of life worldwide. While timely and effective phototherapy and exchange transfusion are well proven treatments for severe neonatal hyperbilirubinaemia, inappropriate or ineffective treatment of hyperbilirubinaemia, at secondary and tertiary hospitals, still prevails in many poorly-resourced countries accounting for a disproportionately high burden of bilirubin-induced mortality and long-term morbidity. As part of the efforts to curtail the widely reported risks of frequent but avoidable bilirubin-induced neurologic dysfunction (acute bilirubin encephalopathy (ABE) and kernicterus) in low and middle-income countries (LMICs) with significant resource constraints, this article presents a practical framework for the management of late-preterm and term infants (≥ 35 weeks of gestation) with clinically significant hyperbilirubinaemia in these countries particularly where local practice guidelines are lacking. Standard and validated protocols were followed in adapting available evidence-based national guidelines on the management of hyperbilirubinaemia through a collaboration among clinicians and experts on newborn jaundice from different world regions. Tasks and resources required for the comprehensive management of infants with or at risk of severe hyperbilirubinaemia at all levels of healthcare delivery are proposed, covering primary prevention, early detection, diagnosis, monitoring, treatment, and follow-up. Additionally, actionable treatment or referral levels for phototherapy and exchange transfusion are proposed within the context of several confounding factors such as widespread exclusive breastfeeding, infections, blood group incompatibilities and G6PD deficiency, which place infants at high risk of severe hyperbilirubinaemia and bilirubin-induced neurologic dysfunction in LMICs, as well as the limited facilities for clinical investigations and inconsistent functionality of available phototherapy devices. The need to adjust these levels as appropriate depending on the available facilities in each clinical setting and the risk profile of the infant is emphasised with a view to avoiding over-treatment or under-treatment. These recommendations should serve as a valuable reference material for health workers, guide the development of contextually-relevant national guidelines in each LMIC, as well as facilitate effective advocacy and mobilisation of requisite resources for the optimal care of infants with hyperbilirubinaemia at all levels.

Intermittent versus continuous phototherapy for the treatment of neonatal non-hemolytic moderate hyperbilirubinemia in infants more than 34 weeks of gestational age: a randomized controlled trial

Intermittent phototherapy with "12 h on and then 12 h off" schedule in comparison with continuous phototherapy for neonatal hyperbilirubinemia may save costs and decrease anxiety of parents. In this non-inferiority-randomized controlled trial, healthy late preterm (>34 weeks) and term neonates with neonatal hyperbilirubinemia under phototherapy for 8 h and total serum bilirubin (TSB) < 18 mg/dL were randomized either into intermittent (IPT) or continuous (CPT) group. Infants in IPT group received 12 h on and 12 h off cycles of phototherapy. In both arms, phototherapy was continued until TSB < 13 mg/dL. Primary outcome was rate of fall of bilirubin. Seventy-five infants (IPT n = 36 vs. CPT n = 39) were enrolled in the study. The rate of fall of bilirubin was significantly higher with "IPT" phototherapy (p = 0.002).

CONCLUSION

In term and late preterm infants with non-hemolytic moderate hyperbilirubinemia, intermittent phototherapy with 12 h on and 12 h off cycles is as efficacious as continuous phototherapy.

Body temperature changes of newborns under fluorescent versus LED phototherapy

OBJECTIVE

To determine changes in body temperature (BT) of hyperbilirubinemic newborns under conventional phototherapy with fluorescent lamps and light emitting diodes (LED) at different irradiances.

METHODS

Otherwise healthy newborn infants >34 wk gestational age (GA) hospitalized for indirect hyperbilirubinemia, requiring phototherapy in the first 10 d of life were enrolled. Infants who received conventional phototherapy with fluorescent lamps (10-15 μW/cm(2)/nm irradiance) were defined as group 1, LED phototherapy of 26-60 μW/cm(2)/nm irradiance as group 2, and LED phototherapy of 60-120 μW/cm(2)/nm irradiance as group 3. Primary outcome measure was mean BT which was defined as arithmetical mean of axillary BT measured at 2 h intervals during the first day of phototherapy.

RESULTS

Thirty patients were enroled in each group. Mean birth weight and GA of the total cohort was 2800 ± 530 g and 36.6 ± 2 wk, respectively. Baseline demographic variables and serum total bilirubin levels were similar among groups. Mean BT was 36.7 ± 0.1 °C in group 1, 36.6 ± 0.2 °C in group 2, 37.7 ± 0.2 °C in group 3. Mean BT was higher in group 3 compared to group 1 (p < 0.001) and group 2 (p < 0.001). Group 1 and group 2 had similar mean BT measurements (p = 0.09). During phototherapy all the patients in group 3 had at least one BT measurement ≥ 37.5 °C and 77 % had BT ≥ 38 °C. Only one patient in group 2 had BT ≥ 37.5 °C which was also ≥ 38 °C. During phototherapy all BT measurements were <37.5 °C in group 1.

CONCLUSIONS

LED phototherapy of ≥ 60 μW/cm(2)/nm intensity significantly increases BT in hyperbilirubinemic newborns.

Can available interventions end preventable deaths in mothers, newborn babies, and stillbirths, and at what cost?

Progress in newborn survival has been slow, and even more so for reductions in stillbirths. To meet Every Newborn targets of ten or fewer neonatal deaths and ten or fewer stillbirths per 1000 births in every country by 2035 will necessitate accelerated scale-up of the most effective care targeting major causes of newborn deaths. We have systematically reviewed interventions across the continuum of care and various delivery platforms, and then modelled the effect and cost of scale-up in the 75 high-burden Countdown countries. Closure of the quality gap through the provision of effective care for all women and newborn babies delivering in facilities could prevent an estimated 113,000 maternal deaths, 531,000 stillbirths, and 1·325 million neonatal deaths annually by 2020 at an estimated running cost of US$4·5 billion per year (US$0·9 per person). Increased coverage and quality of preconception, antenatal, intrapartum, and postnatal interventions by 2025 could avert 71% of neonatal deaths (1·9 million [range 1·6-2·1 million]), 33% of stillbirths (0·82 million [0·60-0·93 million]), and 54% of maternal deaths (0·16 million [0·14-0·17 million]) per year. These reductions can be achieved at an annual incremental running cost of US$5·65 billion (US$1·15 per person), which amounts to US$1928 for each life saved, including stillbirths, neonatal, and maternal deaths. Most (82%) of this effect is attributable to facility-based care which, although more expensive than community-based strategies, improves the likelihood of survival. Most of the running costs are also for facility-based care (US$3·66 billion or 64%), even without the cost of new hospitals and country-specific capital inputs being factored in. The maximum effect on neonatal deaths is through interventions delivered during labour and birth, including for obstetric complications (41%), followed by care of small and ill newborn babies (30%). To meet the unmet need for family planning with modern contraceptives would be synergistic, and would contribute to around a halving of births and therefore deaths. Our analysis also indicates that available interventions can reduce the three most common cause of neonatal mortality--preterm, intrapartum, and infection-related deaths--by 58%, 79%, and 84%, respectively.

Home- versus hospital-based phototherapy for the treatment of non-haemolytic jaundice in infants at more than 37 weeks' gestation

BACKGROUND

Phototherapy is commonly used for the treatment of neonatal jaundice, and home-based phototherapy is now being used in certain centres. Home-based phototherapy offers possible advantages by avoiding prolonged hospital admissions, promoting mother-infant bonding and reducing hospitalisation costs. Potential problems include increased duration of phototherapy, increased readmission to hospital and increased risk of bilirubin encephalopathy.

OBJECTIVES

To compare exclusively home-based versus exclusively hospital-based phototherapy or a combination of home- and hospital-based phototherapy for the management of non-haemolytic jaundice in term infants up to 28 days of age. We planned to include specific subgroups for duration in hospital, method of phototherapy and criteria for readiness for discharge.

SEARCH METHODS

We searched the Cochrane Neonatal Review Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) January 2013, Issue 1, part of The Cochrane Library, MEDLINE (from 1966 to 15 February 2013), CINAHL (from 1982 to 15 February 2013) and EMBASE (from 1988 to 15 February 2013). We searched for abstracts from the Pediatric Academic Societies' Annual Meetings 2000 to 2013. We searched for ongoing trials on the following websites: ClinicalTrials.gov (http://clinicaltrials.gov/) and Current Controlled Trials (http://controlled-trials.com/).

SELECTION CRITERIA

Randomised and quasi-randomised studies comparing term infants who received phototherapy exclusively at home versus phototherapy exclusively in the hospital or a combination of the two for non-haemolytic jaundice.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted data.

MAIN RESULTS

No studies that met the predefined eligibility criteria were identified.

AUTHORS' CONCLUSIONS

No high-quality evidence is currently available to support or refute the practice of home-based phototherapy for non-haemolytic jaundice in infants at more than 37 weeks' gestation.

Is the light-emitting diode a better light source than fluorescent tube for phototherapy of neonatal jaundice in preterm infants?

Background:

Light-emitting diodes (LEDs) are light sources recently used for phototherapy in neonatal jaundice. We compared the efficacy and safety of LEDs with fluorescent phototherapy in the treatment of indirect hyperbilirubinemia.

Materials and Methods:

This controlled trial was conducted on preterm infants hospitalized in neonatal intensive care unit of Shahid Beheshti Hospital in Isfahan (Iran) who needed conventional phototherapy for uncomplicated indirect hyperbilirubinemia. Neonates received phototherapy through devices with LEDs or special blue fluorescent tubes. Primary outcomes included the rate of fall of total serum bilirubin (TSB, mg/dL/hour) and duration of phototherapy (hours). Secondary outcomes were treatment failure and side effects.

Results:

A total of 64 infants with gestational age of 33.5 ± 1.2 weeks, chronological age of 73.0 [SE = 7.3] hours, and weight of 1757.5 ± 147.6 gram were enrolled. The rates of fall of TSB were 0.20 [SE = 0.03] and 0.12 [SE = 0.01] mg/dL/hour in the LED and fluorescent groups, respectively (P = 0.472). Treatment duration was 37.5 ± 26.8 and 45.3 ± 32.1 hours in the LED and fluorescent groups, respectively (P = 0.292). There was no treatment failure in the two groups. Mild hyperthermia was occurred in 3.1% and 28.1% of infants in the LED and fluorescent groups, respectively (P = 0.006).

Conclusions:

LED light source is as effective as fluorescent tubes for phototherapy of preterm infants with indirect hyperbilirubinemia. Considering less frequent side effects, less energy consumption, longer life span, and lower costs, LED phototherapy seems to be a better option than current conventional phototherapy.
