MaFOS-GDM trial: Maternal fish oil supplementation in women with gestational diabetes and cord blood DNA methylation at insulin like growth factor-1 (IGF-1) gene.

BACKGROUND: To evaluate the effects of maternal fish oil supplementation in women with gestational diabetes mellitus (GDM) on birthweight and DNA methylation at insulin like growth factor-1 (IGF-1) gene in their offspring. METHODS: Randomized controlled trial. A total of 120 women with GDM were randomized to one of the two groups between 24 and 28 weeks of the pregnancy: Group 1 (n = 52) received fish oil liquid softgel (Ocean plus®) and Group 2 (Placebo) (n = 68) sunflower oil liquid softgel. The birthweight and DNA methylation at IGF-1 gene of the offsprings were assessed. RESULTS: We observed a significant inverse association between fish oil use during pregnancy and birthweight (ß = -0.18, s.e.:125, P = .04), corresponding to a 250 g lower birthweight among infants born to fish oil users. This association didn't persist in multivariate analysis. Cord blood IGF-1 was lower in fish oil group (P = .001). Cord blood DNA methylation percentages at CpG-1044 and CpG-611 sites of IGF-1 gene promoter 1 (P1) region were higher in fish oil group compared to placebo group (P = .02 and P = .001, respectively). However, CpG-1044 and CpG-611 methylations were not associated to birthweight (ß = 0.04, s.e: 25.1, P = .66 and ß = 0.04, s.e: 22.7, P = 0.66, respectively). CONCLUSIONS: Maternal fish oil use has small effects on birthweight and DNA methylation when given to mothers with GDM at late pregnancy. Future studies are needed to show associations between maternal fish oil use and neonatal DNA methylations. CLINICAL TRIAL REGISTRATION: "Fish Oil Supplementation in Women with Gestational Diabetes".

Signos vasculares retinianos en recién nacidos con cardiopatía congénita crítica: serie de casos / Retinovascular findings in newborns with critical congenital heart disease: A case series

La cardiopatia congènita crítica (CCC) podría provocar cambios en la vasculatura de la retina. Sin embargo, no se dispone de suficientes datos sobre este problema en los recién nacidos. Se evaluaron los cambios en la vasculatura retiniana en una serie de 43 recién nacidos con CCC. Se los dividió en dos grupos según el tipo de CCC; grupo 1 (n= 18): CCC obstructiva izquierda y grupo 2 (n= 25): CCC obstructiva derecha. Se detectaron enfermedades vasculares retinianas en 21 pacientes (48,8%); estas fueron más frecuentes en el grupo 1 (p= 0,04). La patología más común fue la tortuosidad vascular retiniana, observada en seis pacientes (33,3%) del grupo 1 y en 4 (16,0%) del grupo 2. Ninguno de los 21 pacientes con cambios en la vasculatura de la retina requirió tratamiento durante el seguimiento. En un análisis multivariado, solo la CCC obstructiva izquierda estuvo asociada con el desarrollo de enfermedad vascular retiniana (P= 0,03, razón de probabilidades --#91;OR--#93;: 2,8, intervalo de confianza --#91;IC--#93; del 95%: 1,1-7,4). Los cambios vasculares retinianos son frecuentes en los recién nacidos con CCC.

Critical congenital heart disease (CCHD) may cause changes in retinal vasculature. However, there is lack of data in this issue in newborns. We evaluated retinovascular changes in a series of 43 newborn with CCHD. They were divided into 2 groups according to the type of CCHD; group 1 (n= 18): left obstructive CCHD and group 2 (n= 25): right obstructive CCHD. Retinovascular pathologies were detected in 21 patients (48.8%); it was more frequent in group 1 (p= 0.04). The most common pathology was retinal vascular tortuosity in 6 patients (33.3%) of group 1, and 4 (16.0%) in group 2. None of 21 patients with retinovascular changes required any therapy at follow-up. In multivariate analysis, only having a left obstructive CCHD was associated with the development of any retinovascular pathology (P= 0.03, OR: 2.8, CI95%: 1.1-7.4). Retinovascular changes are frequent in newborn patients with CCHD.

Predictive values of plasma KL-6 in bronchopulmonary dysplasia in preterm infants.

BACKGROUND/AIM: It has been suggested that plasma KL-6 increases in premature infants with bronchopulmonary dysplasia (BPD). We aimed to evaluate the predictive values of KL-6 in BPD. MATERIALS AND METHODS: The study was performed in preterm neonates with birthweight ≤1500 g and gestational age ≤32 weeks. Plasma KL-6 levels were measured on postnatal days 1, 7, and 14. RESULTS: BPD was identified in eight of the 28 study infants. On postnatal days 1 and 7, plasma KL-6 levels were similar in infants with BPD [on day 1: 8.9 (7.5-17.8) U/mL and on day 7: 16.8 (10.5-47.7) U/mL] and without BPD [on day 1: 10.8 (9.4-17.2) U/mL and on day 7: 12.9 (5.8-19.3) U/mL] (P = 0.38 and P = 0.13, respectively). On day 14, KL-6 levels were significantly higher in infants with BPD [155.2 (15.3-545.6) U/mL] than they were in infants without BPD [7.9 (7.7-15.6) U/mL] (P = 0.001). The best predictor was KL-6 levels on postnatal day 14 (area under the ROC curve = 0.88; range 0.75-1.0; P = 0.002). At this point, KL-6 level of 59.7 U/mL showed a specificity of 90.0% and negative predictive value of 85.7% for BPD. CONCLUSION: High plasma KL-6 levels on postnatal day 14 in premature infants may predict the development of BPD.

Association of vitamin D deficiency with acute lower respiratory tract infections in newborns.

OBJECTIVE: To determine the association between serum 25-hydroxy vitamin D [25(OH)D] levels and acute respiratory tract infections (ALRTI) in newborns. STUDY DESIGN: The study group consisted of 30 term newborns with ALRTI who were admitted to our neonatal intensive care unit. Controls were 30 healthy newborns with the same age as the study group. Newborns and their mothers were tested for serum 25(OH)D levels, with a low level defined as ≤15 ng/mL. RESULTS: The groups were similar in gestational week, birthweight, postnatal age and gender. Forty-three of the 60 infants (including study and control) had low 25(OH)D levels. The median 25(OH)D levels were lower [9.5 ng/mL (IQR = 7.9-12.2)] in the study group than those of the control group [15.5 ng/mL (IQR: 12-18)] (p = 0.0001). The median serum 25(OH)D levels in the mothers of the study group were also lower than those in the mothers of the control group [11.6 ng/mL (IQR = 9.4-15.8) and 17.3 ng/mL (IQR = 13.7-20.6), respectively] (p = 0.0001). CONCLUSION: Lower blood 25(OH)D levels might be associated with increased risk of ALRTI in term newborn babies. Appropriate vitamin D supplementation during pregnancy and early childhood may enhance newborns' respiratory health.

Effect of Ventilation Support on Oxidative Stress and Ischemia-Modified Albumin in Neonates.

BACKGROUND AND OBJECTIVE: Mechanical ventilation (MV) can induce oxidative stress, which plays a critical role in pulmonary injury in intubated neonates. Ischemia-modified albumin (IMA)-a variant of human serum albumin-is a novel biomarker of myocardial ischemia that occurs due to reactive oxygen species during ischemic insult. This study aimed to investigate IMA production due to oxidative stress induced during MV in neonates. MATERIALS AND METHODS: This study included 17 neonates that were ventilated using synchronized intermittent mechanical ventilation (SIMV; SIMV group) and 20 neonates ventilated using continuous positive airway pressure (CPAP; CPAP group). Blood samples were collected from each neonate during ventilation support and following cessation of ventilation support. Total antioxidant capacity (TAC) and total oxidant status (TOS) were measured using the Erel method. IMA was measured via an enzyme-linked immunosorbent assay kit (Cusabio Biotech Co., Ltd., Wuhan, China). The oxidant stress index (OSI) was calculated as OSI = TOS/TAC. Statistical analysis was performed using SPSS v.18.0 (SPSS Inc., Chicago, IL) for Windows. RESULTS: Among the neonates included in the study, mean gestational age was 34.7 ± 3.8 weeks, mean birth weight was 2,553 ± 904 g, and 54% were premature. There were not any significant differences in mean gestational age or birth weight between the SIMV and CPAP groups. Among the neonates in both the groups, mean IMA, TOS, and OSI levels were significantly higher during ventilation support (102.2 ± 9.3 IU mL(-1), 15.5 ± 1.3 µmol H2O2 equivalent L(-1), and 0.85 ± 0.22 arbitrary units [ABU], respectively), as compared with following cessation of ventilation support (82.9 ± 11.9 IU mL(-1), 13.4 ± 1.3 µmol H2O2 equivalent L(-1), and 0.64 ± 0.14 ABU, respectively) (p = 0.001). Among all the neonates in the study, mean TAC was significantly lower during ventilation support than the postventilation support (1.82 ± 0.28 mmol 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid [Trolox] equivalent L(-1) vs. 2.16 ± 0.31 mmol Trolox equivalent L(-1)) (p = 0.001). There were no significant differences in mean TAC, OSI, or IMA levels between the SIMV and CPAP groups. The mean TOS level during ventilation support and the mean difference in TOS between during and postventilation support was significantly greater in the CPAP group than in the SIMV group. There were no significant relationships between the mean TOS, TAC, OSI, or IMA levels, and gestational age of the neonates. CONCLUSION: SIMV and CPAP activated the oxidative stress and increased the IMA level in neonates; therefore, measurement of IMA and oxidant markers may be useful in the follow-up of lung injury in neonates due to ventilation support. Additional prospective studies are needed to compare the effects of various ventilation methods on oxidative stress and the IMA level in neonates.

Maternal risk factors associated with lead, mercury and cadmium levels in umbilical cord blood, breast milk and newborn hair.

OBJECTIVE: Lead (Pb), mercury (Hg) and cadmium (Cd) are environmental pollutants that are wide spread throughout the world. The present study aimed to investigate the level of exposure to Pb, Hg and Cd during the prenatal period, and the possible routes of maternal exposure to these toxic heavy metals. PARTICIPANTS: The study included 123 mothers and their newborns. Umbilical cord blood samples were collected immediately after delivery, and breast milk and newborn hair samples were collected between postpartum d 3 and 10. RESULTS: Among the 121 cord blood samples that were analyzed, Pb was present in 120 (99.2%) and the mean level was 1.66 ± 1.60 µg dL(-1) (range:

Efficacy of Single Dose Oral Paracetamol in Reducing Pain During Examination for Retinopathy of Prematurity: A Blinded Randomized Controlled Trial.

OBJECTIVE: To investigate the efficacy of paracetamol in reducing pain during examination for retinopathy of prematurity (ROP) in preterm infants. METHODS: A total of 114 infants undergoing eye examination for retinopathy of prematurity screening were prospectively randomized. Topical anesthetic (Proparacaine; Alcaine® drop 0.5%) was applied 30 s before the eye examination in all the infants. The infants in the intervention group (Group 1, n = 58) received 15 mg/kg of oral paracetamol, 60 min before the examination. The control group (Group 2, n = 56) received the same volume of sterile water per oral with an opaque syringe. Primary outcome measurement was pain assessed by Premature Infant Pain Profile (PIPP) score. Secondary outcome measurements were tachycardia (>180 bpm)/bradycardia (<100 bpm), desaturations (<85% for >10 s), and crying time. RESULTS: The groups were similar for gestational age, birthweight or postnatal age at examination. The intervention group had a significantly lower mean PIPP score during eye examination, following insertion of the speculum [Group 1:12 (9-13) vs. Group 2:14 (13-15), p 0.001]. There were no significant differences between the groups with regard to crying time and the number of the patients with tachycardia/bradycardia and desaturation. CONCLUSIONS: Oral paracetamol modestly reduces pain scores during eye examinations. Further cross-over trials on dose and frequency of paracetamol and combination of pharmacological with non-pharmacological approaches and paracetamol alone as a single agent in significant pain reduction are needed.

Exchange transfusion for neonatal hyperbilirubinemia: an 8-year single center experience at a tertiary neonatal intensive care unit in Turkey.

OBJECTIVE: The aim of present study was to evaluate the indications and the complications associated with neonatal exchange transfusion (ET) performed for hyperbilirubinemia. METHODS: This study included overall 306 neonates who underwent ET between 2005 and 2012. The demographic characteristics of patients, causes of jaundice and adverse events occurred during or within 1 week after ET were recorded from their medical files. Those newborns that underwent ET were classified as either "otherwise healthy" or "sick" group. RESULTS: Of the 306 patients who underwent ET, 244 were otherwise healthy and had no medical problems other than jaundice. The remaining 62 patients were classified as sick that had medical problems other than jaundice ranging from mild to severe. The mean gestational age was 37.6 ± 2.5 weeks and the mean peak total bilirubin levels was 25.8 ± 6.6 mg/dl. The mean age at presentation was 5.4 ± 3.8 d for all infants. The most common cause of hyperbilirubinemia was ABO isoimmunization (27.8%). None of newborns died secondary to ET. Three infants had had necrotizing enterocolitis, and also three infants had had acute renal failure. The most common encountered complications of ET procedure were hyperglycemia (56.5%), hypocalcaemia (22.5%) and thrombocytopenia (16%). CONCLUSIONS: Our data showed that ABO isoimmunization was the most common cause of hyperbilirubinemia. Even mortality was not seen, very rare but major gastrointestinal and renal complications were associated with ET. The majority of adverse events associated with ET were laboratory abnormalities mainly hyperglycemia, hypocalcaemia and thrombocytopenia which were asymptomatic and treatable.

Effect of therapeutic hypothermia on C-reactive protein levels in patients with perinatal asphyxia.

OBJECTIVE: To determine the changes in serum C-reactive protein (CRP) levels during therapeutic hypothermia. STUDY DESIGN: Between January 2011 and June 2013, 133 hypoxic-ischemic encephalopathy patients being followed up in the neonatal intensive care unit of Dr. Sami Ulus Maternity and Children's Hospital are prospectively evaluated. Group 1; patients that received therapeutic hypothermia (n = 74) and group 2; patients that did not required therapeutic hypothermia (n = 59). All the patients underwent serial complete blood cell count and CRP assessments; blood cultures were obtained from all the cases at the time of admission and when CRP levels were elevated. RESULTS: Positive blood cultures were encountered in five cases (6.7%) in group 1 while no blood culture-proven septicemia was encountered in group 2. The CRP levels elevated gradually reaching a peak level on the 4th day and then decreased during the therapeutic hypothermia in patients with no blood culture-proven septicemia in group 1. The CRP levels showed statistically significant changes reaching a peak level on the 7th day in patients with blood culture-proven septicemia in group 2. Also, the CRP levels showed no alteration with time in group 2. CONCLUSION: Therapeutic hypothermia itself might be associated with CRP elevation rather than an actual infection.

Exo-pectinase production by Bacillus pumilus using different agricultural wastes and optimizing of medium components using response surface methodology.

In this research, the production of exo-pectinase by Bacillus pumilus using different agricultural wastes was studied. Agricultural wastes containing pectin such as wheat bran, sugar beet pulp, sunflower plate, orange peel, banana peel, apple pomace and grape pomace were tested as substrates, and activity of exo-pectinase was determined only in the mediums containing sugar beet pulp and wheat bran. Then, effects of parameters such as concentrations of solid substrate (wheat bran and sugar beet pulp) (A), ammonium sulphate (B) and yeast extract (C) on the production of exo-pectinase were investigated by response surface methodology. First, wheat bran was used as solid substrate, and it was determined that exo-pectinase activity increased when relatively low concentrations of ammonium sulphate (0.12-0.21% w/v) and yeast extract (0.12-0.3% w/v) and relatively high wheat bran (~5-6% w/v) were used. Then, exo-pectinase production was optimized by response surface methodology using sugar beet pulp as a solid substrate. In comparison to P values of the coefficients, values of not greater than 0.05 of A and B (2) showed that the effect of these process variables in exo-pectinase production was important and that changes done in these variables will alter the enzyme activity.

The effects of phototherapy on eosinophil and eosinophilic cationic protein in newborns with hyperbilirubinemia.

Newborns with jaundice requiring or not requiring phototherapy (PT) are at greater risk of developing asthma later in life. In this study, we investigated the effect of PT treatment on eosinophil and eosinophilic cationic protein (ECP) levels in newborns with severe hyperbilirubinemia. Thirty newborns diagnosed with severe hyperbilirubinemia and exposed to light-emitting diode (LED) PT were enrolled into the study. Total serum bilirubin (TSB) levels, complete blood count and serum ECP concentrations were measured before and after PT. TSB and hemoglobin (Hb) counts were lower after PT (p = 0.001). There was no difference between leukocyte, lymphocyte, neutrophil and platelet count before and after PT. Eosinophil levels were increased after PT, although not significantly. ECP levels were higher after PT (p = 0.006). It may be speculated that newborns treated with LED PT, increased ECP might play a role in developing allergic diseases later in life.

Acute peritoneal dialysis in the newborn period: a 7-year single-center experience at tertiary neonatal intensive care unit in Turkey.

OBJECTIVE: To evaluate the underlying causes and outcomes of neonates who underwent acute peritoneal dialysis (APD). STUDY DESIGN: This report describes a 7-year experience with APD in 77 neonates. RESULTS: Underlying causes requiring APD were acute tubular necrosis (ATN; n = 53), inborn error of metabolism (n = 18), bilateral renal vein thrombosis (n = 3), obstructive uropathy (n = 2; posterior urethral valve and neurogenic bladder), and bilateral renal artery thrombosis (n = 1). Fifteen of the 53 patients developed post-cardiac surgery ATN. The mean dialysis duration was 6.2 ± 10.7 days (range 1 to 90 days). Complications of procedure were hyperglycemia (n = 35), leaking of dialysate (n = 13), peritonitis (n = 10), catheter obstruction (n = 3), bleeding when inserting the catheter (n = 3), exit site infection (n = 2), and bowel perforation (n = 1). There were 57 deaths (74%) in this high-risk group due to underling causes. Of the 20 survivors, 16 patients showed a full renal recovery, but mild chronic renal failure developed in 1 patient and proteinuria with/without hypertension in 3 patients. CONCLUSION: Peritoneal dialysis is an effective means of renal replacement therapy in the neonatal period in the management of metabolic disturbances as well as renal failure. Although major complications of procedure are not so common, these patients have high mortality rates due to the serious nature of the primary causes.

Distribution of congenital anomalies in a neonatal intensive care unit in Turkey.

BACKGROUND: Congenital anomalies are one of the important reasons of mortality and morbidity in newborns. The aim of this study is to determine the incidence, distribution and the mortality of the congenital anomalies in a single neonatal intensive care unit (NICU) from Turkey. METHOD: A retrospective analysis was performed between 2005 and 2012 in NICU using a computerized database. Variables including the type of anomaly, antenatal and postnatal history, gestational age, birth weight, consanguinity and other demographic, clinical and related laboratory variables were extracted from the computerized database using ICD-10 codes. Congenital anomalies were classified according to involved organ systems and also classified as single and multiple anomalies. RESULTS: A total of 1024 newborns with congenital anomaly (CA) (13.7%) were identified among the 7450 hospitalized newborns in NICU. The most affected system was the cardiovascular system (68.8%). Most of the anomalies (67.1%) were single anomalies. Of all, 59.4% had single major, 7.7% had single minor, 9% had single major plus single minor, 18.4% had multiple major and 2% had multiple minor anomalies. On the other hand, 96.3, 1.9, 0.1 and 1.7% of the newborns had malformation, deformation, disruption and dysplasia, respectively. Chromosomal analysis was only performed 24.8% of the newborns with CA and among them, 65.3% of these were in normal limits. The most frequently detected chromosomal abnormality was trisomy 21. Overall, mortality rate was 15.5% among the newborns with CA. CONCLUSION: In conclusion, the most common and mortal CA was cardio-vascular malformations in our hospital. The overall prevalence of cardio-vascular malformations among the newborn was higher than previously reported studies in Turkey. Further, studies with larger sample size are needed to determine CA in Turkey.

Clinical course of community-acquired respiratory syncytial virus pneumonia in newborns hospitalized in neonatal intensive care unit.

INTRODUCTION: Respiratory syncytial virus (RSV) is a major cause of pneumonia in infants worldwide. We aimed to evaluate the clinical course of community-acquired RSV pneumonia in newborns hospitalized in neonatal intensive care unit. MATERIALS AND METHODS: All the newborns diagnosed as pneumonia were prospectively evaluated for RSV infection between November 2010 and April 2011. Fifty-four specimens of nasopharyngeal secretions were tested in parallel with the RAT and the multiplex real time polymerase chain reaction (RT- PCR). Downes' score was used to assess the disease severity in patients with pneumonia. RESULTS: RAT has a sensitivity of 90% and a specificity of 78.5%, as the PCR technique target assay. Four of the patients with RSV pneumonia had secundum atrial septal defect (ASD) and all of four needed mechanical ventilation support. The first day Downes' score was positively correlated with time of intravenous fluid requirement (p= 0.001, r= 0.48), total oxygen need (p= 0.000, r= 0.63), and re-enteral feeding (p= 0.001, r= 0.46). Blood pH (p= 0.031, r= 0.46) were negatively correlated with Downes' score. The second day Downes' score was higher in patients with ASD than those of without ASD (3.8 ± 2.6 vs. 2 ± 1.1, p= 0.01). The most possible risk factor for longer hospital stay was the higher second day Downes' score (p= 0.02 OR: 1.9, CI 95% (1.1-3.2). All infants were discharged from hospital in a good health. CONCLUSION: RAT is sensitive and specific in detecting RSV infections in newborns. Physicians may use Downes' score for evaluation of disease severity in infants with RSV pneumonia. In these patients, ASD has increased the disease severity.

Literature review and outcome of classic galactosemia diagnosed in the neonatal period.

BACKGROUND: The aim of this study was to evaluate the features and outcome of classic galactosemia diagnosed in the neonatal period. METHODS: A retrospective study was carried out on 22 newborns with classic galactosemia who were followed-up in a tertiary neonatal intensive care unit from January 2005 to January 2011. RESULTS: During the study period, 22 (18 boys, 4 girls) newborns were diagnosed with classic galactosemia. The median gestational age was 38 weeks (31 - 42) with a median age of 13 (3 - 23) days on admission. Major presenting symptoms were hepatomegaly (n = 22, 100%), jaundice [n = 19, 86%; including (n = 14, 63%) indirect and (n = 8, 36%) direct hyperbilirubinemia], vomiting (n = 17, 77%), and nuclear cataract (n = 15, 68%). Liver dysfunction (n = 22, 100%), Escherichia coli sepsis (n = 10), purpura fulminans (n = 1), hemophagocytosis (n = 1), and long QT syndrome (n = 1) were also noted. Cataract resolved in 11 (73%) patients with galactose-restricted diet in the first months. Four patients were operated for cataracts. Neurodevelopmental evaluation showed mild psychomotor retardation in one patient, learning disabilities in five, and developmental delay in three. None died from galactosemia or its complications. Patients who were diagnosed before 17 days did not require cataract operation. CONCLUSIONS: Early diagnosis of galactosemia and treatment with a galactose-restricted diet could partially prevent and recover complications of the disease, but not all of them. Cataracts can develop even in the first few weeks of life. Early diagnosis seems important in the prevention of severe cataracts. Therefore, newborn screening for galactosemia should improve morbidity.

Transient neonatal hyperparathyroidism: a presenting feature of sialidosis type II.

Sialidosis is a lysosomal storage disease caused by deficiency of α-N-acetyl neuraminidase-1. Sialidosis is classified into two main clinical variants: type I, the milder form of the disease, and type II, which can in turn be subdivided into three forms: congenital, infantile, and juvenile. We report a female patient with sialidosis type II, presenting with the congenital form of the disease with thrombocytopenia, pulmonary interstitial thickening, and transient secondary neonatal hyperparathyroidism.

Kinetics of Remazol Black B adsorption onto carbon prepared from sugar beet pulp.

Dried sugar beet pulp, an agricultural solid waste, was used for the production of carbon. Carbonised beet pulp was tested in the adsorption of Remazol Black B dye, and adsorption studies with real textile wastewater were also performed. Batch kinetic studies showed that an equilibrium time of 180 min was needed for the adsorption. The maximum dye adsorption capacity was obtained as 80.0 mg g(-1) at the temperature of 25 °C at pH = 1.0. The Langmuir and Freundlich adsorption models were used for the mathematical description of the adsorption equilibrium, and it was reported that experimental data fitted very well to the Langmuir model. Mass transfer and kinetic models were applied to the experimental data to examine the mechanisms of adsorption and potential rate-controlling steps. It was found that both external mass transfer and intraparticle diffusion played an important role in the adsorption mechanisms of dye, and adsorption kinetics followed the pseudo-second-order type kinetic model. The thermodynamic analysis indicated that the sorption process was exothermic and spontaneous in nature.
