Implementing the practice of early skin-to-skin contact among infants ≥35 weeks gestation born vaginally: a quality improvement study.

BACKGROUND: Early skin-to-skin contact (SSC) at birth has been shown to improve neonatal outcomes due to enhanced cardiorespiratory stability, thermoregulation and breastfeeding success. LOCAL PROBLEM: The practice of early SSC was virtually non-existent in our delivery room (DR). METHODS AND INTERVENTIONS: The study was conducted in a newly established tertiary care teaching hospital in Western Rajasthan, India. We aimed to improve the median duration of early SSC from 0 min to at least 60 min over 24 weeks in our DR. A quality improvement (QI) team was formed, and all inborn infants ≥35 weeks born vaginally from 9 March 2017 were included. Using the tools of point-of-care QI, we found the lack of standard operating procedure, lack of knowledge among nursing staff regarding early SSC, routine shifting of all infants to radiant warmer, the practice of prioritising birthweight documentation and vitamin K administration as the major hindrances to early SSC. Various change ideas were implemented and tested sequentially through multiple plan-do-study-act (PDSA) cycles to improve the duration of early SSC. Interventions included framing a written policy for SSC, sensitising the nursing staff and resident doctors, actively delaying the alternate priorities, making early SSC a shared responsibility among paediatricians, obstetricians, nursing staff and family members, and continuing SSC in the recovery area of the DR complex. RESULTS: The duration of early SSC increased from 0 to 67 min without any additional resources. The practice of SSC got well established in the system as reflected by a sustained improvement of 63 min and 72 min, respectively, at the end of 2 months and 4 years after study completion. CONCLUSION: Using the QI approach, we established and sustained the practice of early SSC for more than 60 min in our unit by using system analysis and testing change ideas in sequential PDSA cycles.

90 versus 60 min of early skin-to-skin contact on exclusive breastfeeding rate in healthy infants' ≥35 weeks: A randomised controlled trial.

AIM: To compare the effect of 90 versus 60 min of early skin-to-skin contact (SSC) among vaginally born healthy infants ≥35 weeks of gestation on their exclusive breastfeeding rates and breastfeeding behaviour. METHODS: This parallel-group, open-label, randomised controlled trial enrolled healthy term and late preterm infants born vaginally. Infants in the intervention group received early SSC for 90 min compared to 60 min in the control group. The primary outcome was the proportion of infants on exclusive breastfeeding at 60 ± 12 h. RESULTS: One hundred ninety-eight mother-infant dyads were randomised (99 in each group). The infants in the 90-min SSC group were more likely to be exclusively breastfed at 60 ± 12 h as compared to the 60-min SSC group (RR, 95% CI-1.44, [1.15-1.79], p < 0.01). The modified infant breastfeeding assessment tool score at 60 ± 12 h was significantly higher in the 90-min SSC group (median [IQR]-9, [8, 10] versus 8 [7, 10], p = 0.03]. The proportion of infants on exclusive breastfeeding at 6, 10, and 14 weeks of age was also significantly higher in the 90-min SSC group (RR, 95% CI-1.39 [1.11-1.74], 1.36 [1.08-1.07], and 1.38 [1.08-1.75], respectively). CONCLUSION: Increasing the duration of early SSC showed a dose-response benefit on exclusive breastfeeding rates and breastfeeding behaviour.

Inter-laboratory comparison of plant volatile analyses in the light of intra-specific chemodiversity.

INTRODUCTION: Assessing intraspecific variation in plant volatile organic compounds (VOCs) involves pitfalls that may bias biological interpretation, particularly when several laboratories collaborate on joint projects. Comparative, inter-laboratory ring trials can inform on the reproducibility of such analyses. OBJECTIVES: In a ring trial involving five laboratories, we investigated the reproducibility of VOC collections with polydimethylsiloxane (PDMS) and analyses by thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS). As model plant we used Tanacetum vulgare, which shows a remarkable diversity in terpenoids, forming so-called chemotypes. We performed our ring-trial with two chemotypes to examine the sources of technical variation in plant VOC measurements during pre-analytical, analytical, and post-analytical steps. METHODS: Monoclonal root cuttings were generated in one laboratory and distributed to five laboratories, in which plants were grown under laboratory-specific conditions. VOCs were collected on PDMS tubes from all plants before and after a jasmonic acid (JA) treatment. Thereafter, each laboratory (donors) sent a subset of tubes to four of the other laboratories (recipients), which performed TD-GC-MS with their own established procedures. RESULTS: Chemotype-specific differences in VOC profiles were detected but with an overall high variation both across donor and recipient laboratories. JA-induced changes in VOC profiles were not reproducible. Laboratory-specific growth conditions led to phenotypic variation that affected the resulting VOC profiles. CONCLUSION: Our ring trial shows that despite large efforts to standardise each VOC measurement step, the outcomes differed both qualitatively and quantitatively. Our results reveal sources of variation in plant VOC research and may help to avoid systematic errors in similar experiments.

Floral volatiles evoke partially similar responses in both florivores and pollinators and are correlated with non-volatile reward chemicals.

BACKGROUND: Plants often use floral displays to attract mutualists and prevent antagonist attacks. Chemical displays detectable from a distance include attractive or repellent floral volatile organic compounds (FVOCs). Locally, visitors perceive contact chemicals including nutrients but also deterrent or toxic constituents of pollen and nectar. The FVOC and pollen chemical composition can vary intra- and interspecifically. For certain pollinator and florivore species, responses to these compounds are studied in specific plant systems, yet we lack a synthesis of general patterns comparing these two groups and insights into potential correlations between FVOC and pollen chemodiversity. SCOPE: We reviewed how FVOCs and non-volatile floral chemical displays, i.e. pollen nutrients and toxins, vary in composition and affect the detection by and behaviour of insect visitors. Moreover, we used meta-analyses to evaluate the detection of and responses to FVOCs by pollinators vs. florivores within the same plant genera. We also tested whether the chemodiversity of FVOCs, pollen nutrients and toxins is correlated, hence mutually informative. KEY RESULTS: According to available data, florivores could detect more FVOCs than pollinators. Frequently tested FVOCs were often reported as pollinator-attractive and florivore-repellent. Among FVOCs tested on both visitor groups, there was a higher number of attractive than repellent compounds. FVOC and pollen toxin richness were negatively correlated, indicating trade-offs, whereas a marginal positive correlation between the amount of pollen protein and toxin richness was observed. CONCLUSIONS: Plants face critical trade-offs, because floral chemicals mediate similar information to both mutualists and antagonists, particularly through attractive FVOCs, with fewer repellent FVOCs. Furthermore, florivores might detect more FVOCs, whose richness is correlated with the chemical richness of rewards. Chemodiversity of FVOCs is potentially informative of reward traits. To gain a better understanding of the ecological processes shaping floral chemical displays, more research is needed on floral antagonists of diverse plant species and on the role of floral chemodiversity in visitor responses.

Systematic rotation versus continuous application of 'nasal prongs' or 'nasal mask' in preterm infants on nCPAP: a randomized controlled trial.

To compare whether alternate rotation of nasal mask with nasal prongs every 8 h as compared to continuous use of either interface alone decreases the incidence of nasal injury in preterm infants receiving nasal Continuous Positive Airway Pressure (nCPAP). This was an open-label, three-arm, stratified randomized controlled trial where infants < 35 weeks receiving nCPAP were randomized into three groups using two different nasal interfaces (continuous prongs group, continuous mask group, and rotation group). All infants were assessed for nasal injury six hours post-removal of nCPAP using grading suggested by Fischer et al. The nursing care was uniform across all three groups. Intention-to-treat analysis was done. Fifty-seven infants were enrolled, with nineteen in each group. The incidence of nasal injury was 42.1% vs. 47.4% vs. 68.4% in the rotation group, continuous mask, and continuous prongs groups, respectively (P = 0.228). On adjusted analysis (gestational age, birth weight, and duration of nCPAP therapy), the incidence of nasal injury was significantly less in the rotation group as compared to continuous prongs group (Adjusted Odds Ratio [AOR], 95% confidence interval [CI]; 0.10 [0.01-0.69], P = 0.02) and a trend towards lesser nasal injury as compared to continuous mask group (AOR, 95% CI; 0.15 [0.02-1.08], P = 0.06). However, there was no significant difference in incidence of nasal injuries between continuous prongs versus continuous mask group (P = 0.60). The need for surfactant, nCPAP failure rate, duration of nCPAP, and common neonatal co-morbidities were similar across all three groups.   Conclusion: Systematic rotation of nasal mask with nasal prongs significantly reduced nasal injury among preterm infants on nCPAP as compared to continuous use of nasal prongs alone without affecting nCPAP failure rate.   Trial registration: CTRI/2019/01/017320, registered on 31/01/2019. What is Known: • Use of nasal mask as an interface for nasal Continuous Positive Airway Pressure decreases nasal injury as compared to nasal prongs. What is New: • Rotation of nasal prongs and nasal mask interfaces alternately every 8 h may reduce the nasal injury even further as compared to either interface alone.

800 IU versus 400 IU per day of vitamin D3 in term breastfed infants: a randomized controlled trial from an LMIC.

This open-label, block-randomized controlled trial compared the effect of 800 IU/day and 400 IU/day of oral vitamin D3 supplementation in reducing vitamin D insufficiency (VDI) among healthy-term breastfed infants at 14 weeks of postnatal age. All eligible infants were randomized to receive either 800 or 400 IU/day of oral vitamin D3 (starting within the first week until 14 weeks). The primary outcome was the proportion of infants with VDI (25-OH-D < 20 ng/ml) at 14 weeks. Secondary outcomes were vitamin D deficiency (VDD, < 12 ng/ml), severe VDD (< 5 ng/ml), anthropometry, biochemical or clinical rickets, and any adverse events related to vitamin D toxicity (VDT). Among 102 enrolled infants, the distribution of baseline variables (including cord 25-OH-D levels; 13.0 versus 14.2 ng/ml) was similar in both groups. On intention-to-treat analysis, the proportions of infants with VDI at 14 weeks were significantly lower in the 800 IU group compared to those in the 400 IU group [24% versus 55%; RR 0.44; 95% CI: 0.25-0.76]. The proportions of infants with elevated parathormone (6% versus 26.5%; p = 0.012) and severe VDD (0% versus 12.2%; p = 0.033) were significantly lower in the 800 IU group. Clinical rickets developed in three (6.2%) infants in the 400 IU group. No infant developed VDT.      Conclusions: Daily oral supplementation with 800 IU of vitamin D3 resulted in an almost 50% reduction in the proportion of infants with VDI and prevented the occurrence of severe VDD at 14 weeks of age compared to 400 IU with no evidence of vitamin D toxicity.     Trial Registration: Clinical Trial Registry of India (CTRI/2019/02/017374). What is Known: • Breastfeeding is the ideal source of nutrition for healthy-term breastfed infants; however, vitamin D content of breastmilk is suboptimal. • AAP recommends daily oral supplementation of 400 IU of vitamin D to all healthy-term breastfed infants; however, trials from high-income countries support insufficiency of this dose in maintaining serum 25-OH-D levels >20 ng/ml with no such information from low-middle-income countries. What is New: • 800 IU/day of oral vitamin D3 supplementation among term breastfed infants significantly reduces vitamin D insufficiency at 14 weeks' age as compared to the recommended dose of 400 IU/day. • This higher supplemental dose is safe with no evidence of vitamin D toxicity.

25% Dextrose Versus 24% Sucrose for Heel Lancing in Preterm Infants: A Noninferiority RCT.

OBJECTIVES: To compare the efficacy of 25% dextrose with 24% sucrose for heel-lance analgesia in preterm infants admitted to the NICU. METHODS: In this noninferiority, double-blind, randomized controlled trial, preterm infants born at 28 weeks and 0 days to 35 weeks and 6 days of gestation who were due for a scheduled heel-lance procedure were enrolled. Infants randomly assigned to the intervention arm received 0.5 mL 25% dextrose, whereas infants in the active control group received 0.5 mL 24% sucrose orally just 2 minutes before the heel-lance procedure. The primary outcome was Premature Infant Pain Profile (PIPP) score 30 seconds after the procedure. Secondary outcomes included PIPP scores at 60 and 120 seconds, PIPP-Revised scores at 30, 60, and 120 seconds, and any adverse events. RESULTS: Sixty-four infants were enrolled (32 in each group). The mean (SD) PIPP score at 30 seconds was 6.41 (2.56) in the dextrose group and 7.03 (2.23) in the sucrose group (mean difference, -0.63 (95% confidence interval, -1.85 to 0.60; P = .31). The upper margin of the confidence interval did not cross the predefined noninferiority margin of 2. The mean PIPP scores at 60 (5.03 [2.18] vs 5.39 [1.48]) and 120 (4.75 [1.97] vs 4.94 [1.46]) seconds were also similar. The PIPP-Revised scores between the 2 groups at all time intervals were comparable. One infant in the intervention group had a transient coughing episode. CONCLUSIONS: In preterm infants under intensive care, 25% dextrose is noninferior to 24% sucrose for heel-lance analgesia as assessed by PIPP score.

Can the CROSS protocol be safely implemented in real world scenario with broader eligibility criteria? Experience from a tertiary care centre in India.

BACKGROUND: The Chemoradiotherapy for Oesophageal Cancer Followed by Surgery Study (CROSS) trial established a new benchmark in the management of oesophageal cancer with neoadjuvant chemoradiation followed by surgery with a marked benefit for squamous cell carcinomas (SCCs). We evaluate if the CROSS protocol can be safely implemented with a broader eligibility criteria in a real-world setting. METHODS: A retrospective analysis of 80 patients of SCC oesophagus was performed, who were treated with neoadjuvant chemoradiation with radiation therapy (RT) to 41.4 Gy/23 Fr/4.5 weeks and weekly paclitaxel and carboplatin, followed by surgery at our institute between 2012 and 2019. Eligibility for the use of this regimen was expanded beyond the limits of size and stage allowed in the CROSS trial. RESULTS: The median age of this cohort was 57 years (range: 39-78 years). Most of the patients (77/80; 96.3%) had T3 disease and 25% patients (20/80) had N2/N3 disease. Thirty-three patients (41.3%) had the disease beyond CROSS eligibility criteria. All patients completed planned course of RT and five cycles of weekly chemotherapy were received by 61 patients (76.2%). Overall pathological complete response (pCR) could be achieved in 33 patients (41.3%). Among 33 CROSS ineligible patients, 14 (42.4%) had pCR. Acute grade 3 dysphagia and grade ≥ 3 neutropenia were seen in seven cases (8.3%) and nine cases (10.7%), respectively. At a median follow-up of 16 months, 1-year and 2-year overall survival (OS) were 84.4% (95% confidence interval (CI): 73.5%-91.1%) and 76.3% (95% CI: 63.2%-85.2%), respectively, for the entire cohort. For CROSS ineligible patients, 1-year and 2-year OS were 82% (95% CI: 61.8%-92.2%) and 72.7% (95% CI: 50.4%-86.2%), respectively. On univariate analysis, patients who had pathologically N0 disease had significantly better 2-year OS (85.7% versus 48.4%; p = 0.03) as compared to pathologically N+ patients. On univariate and multivariate analysis, there was no significant difference in OS and progression free survival between CROSS eligible and CROSS ineligible patients. CONCLUSION: CROSS protocol can be safely implemented for carefully selected patients of SCC oesophagus outside clinical trial settings with expanded eligibility criteria.

Diagnosing nail-patella syndrome: can it be so simple?

We describe here an interesting case of a 7-day-old male infant brought with parental concerns of inability to extend both knees. Clinical evaluation revealed dysplastic fingernails, bilateral abnormal patellae, triangular lunules in conjunction with pathognomic iliac horns on pelvic radiographs suggesting the possibility of nail-patella syndrome (NPS). Other competing diagnoses with similar phenotypic features were considered and sequentially excluded. A definitive diagnosis was established by the identification of the principal mutation at the LMX1B gene locus of chromosome 9. NPS is seldom diagnosed in neonates due to the heterogeneity of clinical presentations as well as the subtlety of clinical clues in this population. NPS is a dominantly inherited disorder that is predominantly familial in origin and thus carries important implications for the prenatal diagnosis of future pregnancies as well as pre-emptive surveillance of nephropathy in the index child.

Prioritizing Delivery of Cancer Treatment During a COVID-19 Lockdown: The Experience of a Clinical Oncology Service in India.

PURPOSE: A COVID-19 lockdown in India posed significant challenges to the continuation of radiotherapy (RT) and systemic therapy services. Although several COVID-19 service guidelines have been promulgated, implementation data are yet unavailable. We performed a comprehensive audit of the implementation of services in a clinical oncology department. METHODS: A departmental protocol of priority-based treatment guidance was developed, and a departmental staff rotation policy was implemented. Data were collected for the period of lockdown on outpatient visits, starting, and delivery of RT and systemic therapy. Adherence to protocol was audited, and factors affecting change from pre-COVID standards analyzed by multivariate logistic regression. RESULTS: Outpatient consults dropped by 58%. Planned RT starts were implemented in 90%, 100%, 92%, 90%, and 75% of priority level 1-5 patients. Although 17% had a deferred start, the median time to start of adjuvant RT and overall treatment times were maintained. Concurrent chemotherapy was administered in 89% of those eligible. Systemic therapy was administered to 84.5% of planned patients. However, 33% and 57% of curative and palliative patients had modifications in cycle duration or deferrals. The patient's inability to come was the most common reason for RT or ST deviation. Factors independently associated with a change from pre-COVID practice was priority-level allocation for RT and age and palliative intent for systemic therapy. CONCLUSION: Despite significant access limitations, a planned priority-based system of delivery of treatment could be implemented.

Childhood Scurvy: A Nearly Extinct Disease Posing a New Diagnostic Challenge, a Case Report.

Scurvy is seldom encountered in modern day clinical practice. Children can present with nonspecific features which can mimic several other common conditions. We describe here a four-year-old child who presented with severe pain and weakness of bilateral lower limbs and found to be severely malnourished. The diagnosis of scurvy was suspected in the context of underlying malnutrition after excluding other ominous pathologies. Pathognomic radiological changes clinched the diagnosis, and the best supportive evidence was the dramatic response to vitamin C supplementation.

Root Cause Analysis of Diabetic Ketoacidosis Admissions at a Tertiary Referral Pediatric Emergency Department in North India.

OBJECTIVES: To identify system-based factors contributing to Emergency Department (ED) admissions of children with diabetic ketoacidosis (DKA) and related complications with emphasis on parental and physician awareness and prereferral management. MATERIALS AND METHODS: A prospective observational root cause analysis study of all consecutive admissions of children with DKA to pediatric ED of a tertiary care referral hospital in northern India over a period of 1 year (July 2010-June 2011). Prehospital, health-care system, referral, follow-up, and continuum of care related details were obtained through direct interview of parents and physicians and/or field observations for all enrolled children. RESULTS: Of the 30 children enrolled, 26 (86.6%) were referrals; 16 (61.5%) from first, 7 (26.9%) from second, and 3 (11.5%) from third health-care facility. More than half (n [%], 18 [60%]) had new onset diabetes and belonged to lower socioeconomic strata. Twenty-two (73.3%) were complicated DKA; shock (n [%], 19 [63%]), hypokalemia (n [%], 11 [36%]), and CE (n [%], 3 [10%]) were the most common complications. Most parents were ignorant of diabetes, its symptoms or complicating DKA. Nearly, half of the cases remained undiagnosed (n = 11) at first contact health-care facility; more so for new onset as compared to known diabetes (9/18 vs. 2/8; P = 0.022). The referring hospitals had limited facilities for rapid blood glucose estimation (n [%], 12 [40%]), blood gas analysis (n [%], 6 [20%]) and insulin infusion. On univariate analysis, patients with missed/delayed diagnosis more often had severe and complicated DKA. CONCLUSION: Parental ignorance, lower socioeconomic status, lack of clinical experience, and limited primary health-care facilities were root causes for severe and complicated DKA.
