Abstract
OBJECTIVE To compare the entrance skin doses (ESD) before and after implementation of a radiation safety policy in neonates (RSN), which focused on clinician-directed technical specifications on the digital X-ray machine. METHODS Prospective observations included two sets of X-rays: Before (BRSN) and after (ARSN) implementation of RSN (documented indication for X-ray/expected posttest findings, settings of 40 kVp, 0.5 mAs, film-focus distance 100 cm, gonadal-shield, optimal collimation, and post-shoot image-enhancement). RESULTS 33 and 32 X-rays were analyzed in respective groups. Mean (SD) of calculated and machine-quantified ESD (µGy/m2) was higher in BRSN group as compared to ARSN group (P <0.001). All ARSN X-rays were interpretable for expected post-test findings. CONCLUSION Clinicians' cognizance of ability to make consequential bedside technical specifications, can reduce ESD without affecting interpretability. These single observations could have a larger impact in sick neonates, where multiple X-rays are done.

Abstract
OBJECTIVES To document the adverse cardiorespiratory events following first routine immunization in preterm neonates. METHODS We retrieved records of neonates with gestational age ≤30 weeks, who developed cardio-respiratory events after first vaccines before discharge. Our Unit's protocol is to administer Bacillus Calmette-Guerin (BCG), hepatitis B vaccine to those discharged at <8 weeks postnatal age. Hexavalent, BCG, pneumococcal vaccine and rotavirus vaccines are given at 8 weeks of age, if hospital stay is predicted to be longer. Unit compliance to vaccination administration at appropriate ages were also measured. RESULTS Data of 161 neonates ≤ 30 weeks (17.4% <27 week) who completed care in the unit was studied. Cardio-respiratory adverse events were reported in 21(13.7%). None of these required initiation of invasive ventilation. High flow nasal cannula therapy and caffeine restart were required for these events in 14 (9.3%) and 6 (3.9%) neonates, respectively. Lower gestational age, bronchopulmonary dysplasia and sepsis were significant risk factors on univariate analysis. On multivariate analysis, continued need for respiratory support at 4 weeks of age (P=aOR 14.5 (95% CI 5-59.1) was the only independent risk factor for post-vaccination cardiorespiratory adverse events. Of 38 who were not vaccinated at recommended ages by unit policy, 25 were missed opportunities, the rest were deemed unstable for vaccinations at that age by the clinical team. CONCLUSION Adverse cardiorespiratory events were uncommon after first vaccinations in very preterm neonates. Administering vaccines to these before discharge would allow monitoring for these events, especially for those who require long-term respiratory support.

Abstract
BACKGROUND AND OBJECTIVES Many sick neonates receive antibiotics for the clinical diagnosis of probable/possible sepsis. Reports suggest rampant antibiotic use in culture-negative sepsis. We introduced an antibiotic stop policy (ASP), by defining 'completed course duration of antibiotics' in the setting of culture-negative suspected healthcare-associated infection (HAI). Antibiotic overuse days (AOD) before antibiotic stop policy (BASP) and after antibiotic stop policy (AASP) were compared. METHODS This descriptive analytical study was conducted to measure the change in AOD after implementing ASP in culture-negative HAI. We also sought to evaluate situations in which antibiotic overuse is likely (lower gestation, ventilation, central lines) and safety of the ASP, measured as not having to restart antibiotics in the week following completed course. RESULTS A total of 126 neonates were initiated on a new antibiotic (started or changed) for suspected HAI. Of these, 43 were excluded. Patient days of 5175 and 5208 were analyzed in BASP and AASP, respectively. Implementation of an ASP reduced AOD (from 14.49 to 3.26 AOD per 1000 patient days; p value <0.01). Safety was ensured; the number of babies who had to be restarted on antibiotics within 1 week of stopping therapy was similar in both groups. All-cause mortality and relevant morbidities were comparable between groups. CONCLUSIONS A significant decrease in AOD after the introduction of an ASP was noted, in neonates with culture-negative suspected HAI. This difference was noted even in the most vulnerable extreme preterm babies and those requiring ventilation and central lines.

Abstract
OBJECTIVES To explore the utility of endotracheal aspirates (ETA) for analyzing microbiological yield, incidence, risk factors for VAP, and clinically relevant outcomes. METHODS Ventilated neonates suspected to have VAP were studied prospectively; they were classified as "VAP" or "No VAP" based on a predefined combination of clinical, radiological, and laboratory criteria. The microbiological yield from blood and ETA cultures was analyzed. RESULTS Of 165 neonates who were ventilated for > 48 h, 65 were suspected of having VAP. Thirty-six (22.9%) were classified as VAP. Microbiological agents could be identified in 31 cases (86.1%) by ETA/blood cultures. Acinetobacter sp was the common organism identified. Duration of ventilation, and a higher number of reintubations before suspicion of VAP were significant risk factors for VAP. Positive ETA culture was associated with a greater duration of oxygen therapy and ventilation days after suspicion of VAP. CONCLUSIONS The commonest culture yield from ETA in those suspected to have VAP was gram-negative bacilli. Duration of ventilation and reintubations were identified as significant risk factors for VAP. These are potentially modifiable factors. Positive ETA culture was associated with longer needs for respiratory supports. Negative ETA culture might encourage clinicians to stop antibiotics.

Abstract
OBJECTIVE This research aimed to study the impact of early parent participation program (EPPP) for preterm infants in neonatal intensive care unit (NICU) on physiological instability, breastmilk feeding rates, and discharge timing. STUDY DESIGN Families of 147 infants born between 28 and 33 weeks' gestation were randomized at birth to EPPP group or conventional care (CC). Families in the EPPP group were trained soon after admission by using a structured education program and encouraged to spend more time with their baby. Soon after enrolment (day of life 1 to 2), they would sequentially participate in daily NICU care processes such as orogastric tube feeding, nesting, oil massages, diaper changes, and daily weight checks. Families in the CC group would undergo the same after their infant was off parenteral nutrition and respiratory support. Proportion of infants having physiological instability (significant apnea, feeding intolerance, or needing investigation for sepsis) in two groups was compared. RESULTS There was a significant reduction in the proportion of infants with physiological instability (feeding intolerance) in the EPPP group (relative risk = 0.70 [0.52-0.94], p = 0.016). Infants in EPPP group had a trend toward higher breastmilk feeding rates at discharge (66 vs. 51%, p = 0.076). CONCLUSION Very early parent participation was feasible in the NICU and led to decrease in physiological instability in preterm infants. KEY POINTS · Family-integrated care is beneficial; however, it is often started later in the NICU course.. · This trial showed that very early involvement of family in NICU care processes is feasible and safe.. · Structured parent participation started very early improves physiological stability in preterm infants (mainly tolerance to feeds)..

Abstract
BACKGROUND Metabolic bone disease (MBD) is a morbidity of multifactorial etiology with a high incidence in very preterm infants. We planned to study the incidence of MBD after implementation of bone health focussed nutritional strategy (BNS) in those <30 weeks gestation at birth. METHODS This prospective cohort study including preterm newborns (<30 weeks) who received nutrition that incorporated (a) Early initiation of intravenous potassium phosphate; (b) Early enteral supplementation with multicomponent human milk fortifier at enteral feed tolerance of 40 mL/kg/day feeds itself; and (c) Weekly phosphorus measurements with optimization of enteral intakes. Incidence of MBD at 4 weeks of postnatal age and beyond were analyzed. Other relevant safety and clinical outcomes were measured. RESULTS Of the 67 included neonates receiving BNS, 20.9% were classified as MBD. There was a low rate of hyper-phosphatemia (4.5%) and hyperkalemia (2.9%). Full enteral feeds were achieved by median (IQR) of 6 (5,7) postnatal days. CONCLUSION In preterm newborns (24-30 weeks) MBD incidence was 20.9% after BNS was implemented. Intravenous potassium salt of phosphorus and early use of HMF were safe and feasible.

Abstract
BACKGROUND Certain morbidities are inevitable in preterm infants; the challenge lies in minimizing them. Anemia of prematurity is multifactorial. Therapy largely depends on adult red blood cell transfusions (RBCT); which inherently, are not without problems. Most literature in this respect are retrospective or evaluate individual stratagems to reduce RBCT. METHODS This observational analytical study was planned to compare need for RBCT, before and after institution of blood conservation strategies (BCS). All those ≤30 weeks gestation at birth during two-time epochs were included (Before BCS: retrospective; After BCS: prospective). BCS constituted of delayed cord clamping (DCC), strict sampling indications, micro-sampling with point-of-care testing (MS-POCT) and adherence to RBCT thresholds. RESULTS Of 45 enrolled neonates in each group, proportion of those requiring even 1 RBCT was significantly reduced after BCS [51.1% vs. 26.7%, p = 0.02, OR 0.35, 95%CI (0.14, 0.84)]. Calculated cumulative blood volume losses (35.3 ml vs. 21.9 ml) and loss per kilogram birth weight (35.3 ml/kg vs. 20.12 ml/kg) were significantly lower after BCS (p = 0.0036). Need for >1 RBCT, mean lowest Hb, mean maximum-hemoglobin drop, need for arterial lines were reduced. Adherence to RBCT thresholds were acceptably good in both time epochs. However, the compliance to DCC was low in both groups, identifying one area of focus with scope for massive improvement. CONCLUSIONS Need for RBCT transfusions largely attributable to reduced blood losses for lab analysis were reduced after BCS. Installation of in-house MS-POCT seemed to be the pivotal factor. Units that care for very preterm infants must make attempts to procure MS-POCT equipment.

Abstract
Abstract
Background Intensivists indeed discharge neonatal intensive care unit (NICU) graduates after a period of physiological stability. There is, however, a real risk of life-threatening events at home. Survival after such episodes depends on time from arrest to initiation of basic life support (BLS). It is rational to train parents who would be first responders. We sought to measure objectively and prospectively, effect of BLS training on parents of NICU graduates on the psychomotor, cognitive, and affective domains of human learning.
Methods After face-to-face training sessions, proportion of home caregivers who obtained 100% marks on a pretested performance checklist for psychomotor skills of BLS on a mannequin were measured. Two other domains of learning and number of attempts required to obtain desirable results were also analyzed.
Results Median (interquartile range [IQR]) birth weight of the high-risk neonates was 1,050 g (930, 1570) and median gestational age was 29 (IQR 28, 33) weeks. More than 75% of parents had no prior exposure to BLS training. Among 46 trained caregivers, 80.4% achieved the desired score of 5 in the psychomotor performance checklist on the first attempt. A maximum of two attempts was required to reeducate and achieve score of 5 in the remaining caregivers. Forty-two (91.3%) caregivers obtained full marks on cognitive domain test. All caregivers responded positively toward affective domain questionnaire.
Conclusion It is possible to train parents in BLS measures and demonstrate their psychomotor skills on a mannequin effectively. No parents who were approached refused training or indicated anxiety in learning the skills required.

Abstract
Guidelines on micronutrient supplementation in moderate to late preterm infants (MLP) are mostly extrapolated from those for smaller preterms, largely due to lack of systematic studies on physiological status in this special group of infants. Actual practices vary widely. We prospectively studied iron status by measurement of serum ferritin (SF) and haematological indices at 4 months corrected age in infants born between 32 and 36 weeks gestation (MLP), after they received 2 mg/kg/day oral iron from 6 weeks of postnatal age. Proportion of MLP having normal iron status (iron replete), i.e., neither iron deficiency (ID) nor iron excess was measured. ID anaemia, growth and development, risk factors for ID were also analysed. Of the 82 infants studied, 78% babies were late preterm. Seventy-four (90.3%) were iron replete (no deficiency or excess) at 4 months. High variability in SF levels (minimum of 9.8 to maximum of 252.2 μg/l) with median (IQR) of 57.45 μg/l (37.02-98.85) was noted in the entire cohort; and also within those who were iron deficient with median (IQR) of 17.50 μg/l (11.70-18.90). There was no difference in haematological indices of ID infants when compared to those with normal iron status. Inspite of oral iron supplementation with reasonable compliance, 8.5% MLP were iron deficient at 4 months corrected age. The high variability noted in SF levels could justify the need for monitoring iron status in this group of preterm infants. This could quintessentially aid individualization of iron supplementation advice.

Abstract
AbstractAutosomal recessive polycystic kidney disease, described as a congenital hepatorenal fibrocystic syndrome, is a significant inherited cause of end stage renal failure in children with reported incidence of 1 in 20,000 live births. The clinical spectrum is wide. Antenatal findings of echogenic reniform enlarged kidneys associated with evidence of intrauterine renal failure in the form of severe oligoamnios are pathognomonic. Postnatal illness ranges from fatal respiratory failure due to pulmonary hypoplasia in neonates to chronic kidney disease in children, or later presentation of ductal plate malformation and portal hypertension. Advances in genetic diagnostic techniques have allowed recognition of genotypes. We report a novel homozygous missense variant on exon 22 of PKHD1 gene (chr6:51915067G > A; c.2167C > T) that results in the amino acid substitution of cysteine for arginine at codon 723 (p.Arg723Cys). The affected neonate presented with antenatal anhydramnios, classical radiological features, and severe hypoxic respiratory failure likely due to pulmonary hypoplasia and succumbed. The parents were found to be heterozygous carriers. Detection of the specific variant in the proband facilitated prenatal investigation in the next pregnancy.

Abstract
BACKGROUND AND OBJECTIVES Hammersmith Neonatal Neurologic Examination (HNNE) is used to identify term and preterm infants at risk of neurodevelopmental disability. The test is recommended at corrected term age in preterm; and around 2 weeks postnatal age in term neonates. As the current trend is to discharge based on physiological stability, it may not be feasible to perform HNNE at recommended age. The authors investigated whether predictive ability of the test for neurodevelopmental disability remained unchanged if performed early (before discharge). METHODS The authors enrolled preterm and at-risk term neonates. HNNE PE was performed before discharge in all infants. The test was repeated in preterm infants at 40 weeks postmenstrual age and in term neonates at 2 weeks of age (HNNE RA). Neurodevelopmental disability was assessed at 1 year of age. RESULTS HNNE PE was done in 125 neonates (103 preterm, 22 term neonates). HNNE RA was done in 58% infants. Neurodevelopmental disability was assessed in 84 (67%) of infants. Neurodevelopmental disability was noted in 14/84 (16.6%) babies. The receiver operating characteristic curve of raw scores showed that area under the curve for HNNE PE (0.71) and HNNE RA (0.66) were similar. The sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio for both the tests were similar for a cutoff optimality score of 32.5. HNNE PE could be performed up to 4 weeks earlier than HNNE RA with the same predictive ability for neurodevelopmental disability. CONCLUSIONS HNNE PE was as reliable as HNNE RA in predicting neurodevelopmental disability at 1 year of age. Completion of the test is assured and provides several weeks lead time for early intervention.

Abstract
AbstractInherited diarrheal disorders cause serious morbidity resulting in dependence on intensive care and parenteral nutrition. Microvillus inclusion disease (MVID) has been classically described and results from mutations in the gene coding myosin Vb, which is responsible for enterocyte polarization. Newer reports of mutations resulting in truncated syntaxin 3 (STX3) and Munc18-2 (STXBP2) proteins have been elucidated as causative. To date, five cases of STX3 abnormalities resulting in MVID have been described. We report an infant who presented with congenital diarrhea and was determined to have a rare mutation of STX3. This new finding would be beneficial in future functional genotype–phenotype correlation studies.

Abstract
Abstract
Background Extremely low birth weight (ELBW) neonates are the sickest patrons of neonatal intensive care. Authors have attempted to predict outcomes based on perinatal factors very soon after birth. Allowing a longer duration for clinical assessment may permit meaningful assessments. Postponing these predictions to several weeks does not offer succour.
Methods We retrospectively studied association of predefined perinatal factors and clinical status of 53 ELBW infants in the first 72 hours of life; with death or continued need for respiratory support at 4 weeks of life separately (RS4).
Results Mean and standard deviations of birth weight and gestational age were 781.8 (±130.7) g (range: 510–990 g) and 26.4 (±1.5) weeks (range: 24–30 weeks), respectively; 32.9% were < 750 g at birth. Of the 53 neonates, 20.7% babies expired and 47.1% required RS4 (66% neonates suffered composite outcome of death/RS4). Need for > 0.3 fraction of inspired oxygen (FiO2) beyond 72 hours of life demonstrated strong association with death/RS4 (odds ratio [OR] 14.3; 95% confidence interval [CI] 3.2–63.0). Need for chest compression (OR 15.3; 95% CI 1.4–167.2) and shock (OR 14.2; 95% CI 2.7–72.8) were significantly associated with mortality.
Conclusion FiO2 requirement of > 0.3 at 72 hours reasonably predicts death or dependence on respiratory supports at 4 weeks of life.

Abstract
Very preterm babies, after their initial need for rigorous supports, remain in intensive care units for maintaining euthermia. We compared proportion of 'hypothermia OR hyperthermia episodes(HHE)'; physiological instability events; and weight gain in stable preterm babies between 29 and 32 weeks nursed in Cocoon warmer (CW) vs. servo-controlled Radiant warmer(RW) in the intervals between kangaroo mother care. Sixty-six babies were randomized to CW and 59 to RW; number of temperature recordings over 24 h in CW were 1417 and 1271 in RW. HHE were comparable in RW (4.64%) and CW (5.15%); RR 1.1(0.79-1.55), p = 0.6. The combined incidence of physiological instability events was less in CW than RW [(RR 0.49 (0.25-0.97), p = 0.06]. Mean weight gain was similar, being 13.4 ± 6.1 g/day in CW and 12.8 ± 4.9 g/day in RW (p = 0.55). CW was comparable to RW in thermoregulation of hospitalized stable preterm babies.

Abstract
When breastmilk is insufficient to meet planned feed volumes, neonatologists need to continue parenteral nutrition (PN) or use formula. This trial conducted at a tertiary care unit in South India between August 2014 and April 2016 compared time to full feeds in preterms fed 'mother's milk alone(MM)' vs. 'hybrid feed-mother's milk supplemented with formula(HF)'. We also compared time to regain birth weights, duration of PN, feed intolerance, Necrotizing Enterocolitis stage 2 or more, all-cause mortality, Extrauterine growth restriction, Healthcare associated infections, exclusive breast milk feeding rates at discharge, Retinopathy of prematurity requiring laser therapy, abnormal neurosonogram and oxygen dependency at 28 days. Neonates between 27 and 32 weeks were randomized into MM/HF when breast milk was insufficient. HF received formula to reach targeted feed volumes. MM received more PN to meet fluid requirements. 54 babies were analyzed in MM and 58 in HF. Time to full feeds were similar-MM (14.1 ± 4 days); HF (13.5 ± 4 days), p = 0.45. Exclusive breast milk feeding rates at discharge were higher in MM when compared to HF (74% vs. 51%). Other secondary outcomes were similar between groups. When mother's milk is unavailable in sufficient quantities, preterm babies may receive hybrid feeds. (Clinical trials registry of India no. REF/2016/02/006622).

Abstract
Familial hemophagocytic lymphohistiocytosis (FHLH) is a fulminant rapidly progressive disorder characterized by uncontrolled immune system activation. Over the last decade, STXBP2 mutations have been reported as causative. We report a baby with typical clinical features and supportive laboratory findings, who had a homozygous missense variation in exon 19 of STXBP2 that results in an amino acid substitution of aspartic acid for glycine. Adding to the currently scant literature on this variation may contribute to the database pool and help to confirm assertion of pathogenicity in FHLH.

Abstract
AbstractUmbilical vein catheterization is considered a critical requirement in preterm neonates for the administration of fluids and parenteral nutrition. However, inadvertent migration and malposition are known to cause complications that are often life-threatening. We describe a neonate with parenteral nutrition-associated lipid ascites owing to extravasation from an umbilical vein cannula. Fatality was averted due to prompt recognition and paracentesis that was therapeutic and confirmed the diagnosis as well.

Abstract
BACKGROUND Aggressive nutrition may benefit early growth; nevertheless, effects on neurodevelopmental outcomes are unclear. We planned a descriptive analytical study to compare survival without neurodevelopment disability (NDD) at 1 year in 2 groups during 2 time epochs-before and after implementation of early optimal nutrition strategies. NDD was defined as any one of the following: mental and/or motor development quotient < 85 at 12 months of age, corrected for prematurity; Denver Developmental Screening Test abnormal/suspect in even 1 domain out of the 4 domains; seizures; requirement of hearing aid; or blindness in 1 or both eyes. We also compared mortality, survival without bronchopulmonary dysplasia, necrotizing enterocolitis (NEC), retinopathy of prematurity (ROP), intraventricular hemorrhage, periventricular leukomalacia, sepsis, metabolic bone disease (MBD), and extrauterine growth restriction (EUGR). METHODS Preterm neonates born between 27 and 32 weeks' gestation were included. The prospective study group (AO) was recruited after implementation of early optimal nutrition policy. The comparative retrospective cohort (BO) received nutrition based on clinicians' decisions. Both groups were followed up using a structured plan till 1 year corrected age. RESULTS 137 neonates were enrolled in AO and 151 in the BO cohort. There was no statistically significant difference in survival without NDD at 1 year-75.5% in AO vs 72.1% in BO, odds ratio 0.84 (95% CI 0.5-1.6). Babies who received early optimal nutrition had less NEC, EUGR, and ROP requiring laser therapy but more MBD. CONCLUSION There was no difference in survival without NDD in early optimal nutrition cohort compared to the cohort before implementation of the nutrition strategy. Short-term benefits themselves may justify the need for early optimal nutrition.

Nasal Injury with Continuous Positive Airway Pressure: Need for "Privileging" Nursing Staff. Indian J Pediatr 2019; 86:595-598. [PMID: 31020593 DOI: 10.1007/s12098-019-02960-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2018] [Accepted: 04/09/2019] [Indexed: 11/25/2022]
Abstract
OBJECTIVES Use of continuous positive airway pressure (CPAP) in neonates is associated with nasal injury (NI) for which various risk factors related to the neonatal characteristics and properties of interfaces used have been reported. "Privileging" of nursing staff may influence safety and incidence of adverse events. In this prospective cohort study, authors studied the incidence of NI and risk factors for NI in babies requiring CPAP after privileging staff for CPAP care bundles. METHODS All neonates on CPAP over a 6-mo period were included. Standard operating procedures were formulated and staff of NICU (nurses and doctors) were educated at the start of the study and periodically in 6 comprehensive areas of care- encompassing position of head, prongs and cap; nasal suctioning and interruptions in pressure on the nose. The staff who completed the training and evaluation were declared as "privileged". NI (measured by a standard staging) and risk factors were predefined and studied. RESULTS Of the 51 babies who required respiratory supports, 35 required CPAP care. Nine babies (25%) out of 35 who required CPAP had NI (2, 4, 3 babies had stages 1, II and III of NI respectively). Seventy seven percent of babies were cared for by privileged nurses. NI was significantly higher when cared for by non-privileged staff (66% vs. 11%, unadjusted RR = 6.75, 95%CI 2.16-21.09). All other risk factors were not significant. CONCLUSIONS NI was noted in 25% neonates on CPAP, and those cared for by non-privileged staff had higher chances of NI. Quality processes and emphasis on continued monitoring and evaluation of nursing skills may help prevent these untoward complications.

Abstract
BACKGROUND Streptococcus mutans is one of the most important cariogenic species of the human oral microbial flora. Biofilm style of microbial growth thought to resist the actions of antimicrobials. AIM The purpose of this study was to evaluate the antimicrobial efficacy of Triphala, and 0.2% chlorhexidine against S. mutans biofilm formed on tooth substrate. SETTINGS AND DESIGN Randomized control trial. METHODS Extracted human mandibular premolars sectioned below the cemento-enamel junction were placed in the tissue culture wells exposing the crown surface to S. mutans to form a biofilm. At the end of 3 rd and 7 th day, all groups were treated for 10 min with the test solutions and control and were analyzed qualitatively and quantitatively. STATISTICAL ANALYSIS USED One-way ANOVA. RESULTS Qualitative assay with 3 days biofilm showed complete inhibition of bacterial growth with Triphala, but 0.2% chlorhexidine and saline showed the presence of bacterial growth. In quantitative analysis, 0.2% chlorhexidine and Saline treated tooth samples have shown 1052 Χ 10(4) ± 15.1 Χ 10(4) CFU/ml, 141.3 Χ 10(9) ± 2.1Χ10(9) CFU/ml, respectively. Qualitative assay with 7 days biofilm on crown portion showed dense growth when treated with 0.2% chlorhexidine and saline, whereas Triphala has shown minimal growth. In Quantitative analysis, Triphala showed statistically significant result when compared with 0.2% chlorhexidine and saline. CONCLUSION Triphala showed statistically significant antibacterial activity against S. mutans biofilm formed on tooth substrate. The incorporation of Triphala in mouth rinse could prove to be effective in reducing S. mutans count in the oral cavity.

Hematopoietic PBX-interacting protein (HPIP) is over expressed in breast infiltrative ductal carcinoma and regulates cell adhesion and migration through modulation of focal adhesion dynamics. Oncogene 2014; 34:4601-12. [PMID: 25486428 DOI: 10.1038/onc.2014.389] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2014] [Revised: 09/23/2014] [Accepted: 09/27/2014] [Indexed: 12/15/2022]
Abstract
The scaffolding protein, hematopoietic PBX-interacting protein (HPIP/PBXIP1), regulates cell migration necessary for cancer cell dissemination. However, the mechanism that governs this process remains unknown. We show here that HPIP expression is associated with stages of breast cancer where cell dissemination results in poor patient outcome. Our investigation finds a novel association of HPIP with focal adhesion kinase (FAK) regulating FA dynamics. Interestingly, this interaction that led to activation of FAK protein was mediated by the C-terminal domain of HPIP and not the typical integrin-binding motif. Further, short hairpin RNA-mediated knockdown of FAK expression significantly reduced HPIP-induced cell migration indicating participation of FAK pathway. Live-cell time-lapse imaging and biochemical analysis further established the role of HPIP in microtubule-induced FA disassembly. We also found that HPIP-mediated MAPK activation led to phosphorylation and subsequent activation of calpain2, and the activated calpain2 in turn proteolyses FA protein, talin. Interestingly, HPIP is also proteolysed by calpain2 in breast cancer cells. The proteolysis of HPIP and talin by calpain2, and the activation of calapin2 by HPIP-mediated MAPK phosphorylation, is a novel regulatory axis to modulate the cell migration signal. Together, we have determined HPIP as a novel activator of FAK and a new substrate of calpain2. These molecular interactions between HPIP and FAK, and HPIP and calpain2 regulate cell adhesion and migration through modulation of FA dynamics.

Abstract
INTRODUCTION The purpose of this study was to evaluate the antimicrobial efficacy of Triphala, green tea polyphenols (GTP), MTAD, and 5% sodium hypochlorite against E. faecalis biofilm formed on tooth substrate. METHODS Extracted human teeth were biomechanically prepared, vertically sectioned, placed in the tissue culture wells exposing the root canal surface to E. faecalis to form a biofilm. At the end of the 3rd and 6th weeks all groups were treated for 10 minutes with the test solutions and control and were analyzed qualitatively and quantitatively. RESULTS Qualitative assay with 3-week biofilm showed complete inhibition of bacterial growth with Triphala, MTAD and NaOCl, except GTP and saline, which showed presence of bacterial growth. In quantitative analysis, GTP- and saline-treated tooth samples have shown 1516 +/- 17.2 CFU/mL, 156.4 x 10(9) +/- 3.1 x 10(9) CFU/mL respectively. Qualitative assay with 6-week biofilm showed growth when treated with Triphala, GTP and MTAD whereas NaOCl has shown complete inhibition. All groups except NaOCl showed eight log reduction when compared to control when analyzed quantitatively. CONCLUSIONS 5% sodium hypochlorite showed maximum antibacterial activity against E. Faecalis biofilm formed on tooth substrate. Triphala, green tea polyphenols and MTAD showed statistically significant antibacterial activity. The use of herbal alternatives as a root canal irrigant might prove to be advantageous considering the several undesirable characteristics of NaOCl.

Abstract
BACKGROUND Thromboxane A2 (TXA2) is a positive feedback lipid mediator that is generated upon stimulation of platelets with various agonists. Aspirin works as an antithrombotic drug by blocking the generation of TXA2. The aim of this study was to evaluate the role of the purinergic P2Y receptors in thrombin-induced TXA2 generation. RESULTS PAR1-activating peptide (SFLLRN), PAR4-activating peptide (AYPGKF), and thrombin, induced the activation of cytosolic phospholipase A2 (cPLA2), release of arachidonic acid (AA) from membrane-bound phospholipids, and subsequent TXA2 generation in human platelets. The actions of these agonists were significantly inhibited in the presence of the P2Y12 receptor antagonist, AR-C69931MX, but not the P2Y1 receptor antagonist, MRS2179. In addition, AYPGKF- and thrombin-induced TXA2 generation was significantly reduced in platelets from mice dosed with clopidogrel, confirming the results obtained with the human platelets. Also, Pearl mouse platelets that lack releasable nucleotides generated significantly less TXA2 when compared with the wild-type littermates in response to PAR stimulation. Inhibition of extracellular signal-regulated protein kinase 1/2 (Erk 1/2) activation using U0126, an inhibitor of MAP kinase kinase (MEK), suppressed PAR-mediated cPLA2 phosphorylation and TXA2 generation. Further, platelets that were pretreated with AR-C69931MX, as well as Pearl mouse platelets, displayed the reduced levels of Erk1/2 phosphorylation upon stimulation with the PAR agonists. CONCLUSIONS Based on these findings, we conclude that thrombin-induced Erk1/2 activation is essential for PAR-mediated TXA2 generation, which is potentiated by the P2Y12 receptor-mediated signaling pathway but not the P2Y1 receptor-mediated signaling pathway. Finally, using selective inhibitors of Src kinases, we show that PAR-mediated Src activation precedes Erk1/2 activation.

Abstract
Giant cell tumours of bones are uncommon and are usually found in the epiphyses of long bones. They are rare in flat bones (<10%). The tumour has to our knowledge never been described in the hyoid bone, although 18 cases have been reported in the cartilagenous laryngeal skeleton. We report a giant cell tumour of the hyoid bone in a 45-year-old man, which we excised along with the left half of the hyoid bone. It recurred locally one year later and was cured by excision and split course radiotherapy. The patient is disease-free after 30 months of follow-up.

A nonpeptide integrin antagonist can inhibit epithelial cell ingestion of Streptococcus pyogenes by blocking formation of integrin alpha 5beta 1-fibronectin-M1 protein complexes.

Abstract
Streptococcus pyogenes can be efficiently internalized by a variety of human epithelial cells. beta-lactam antibiotics, commonly used to treat S. pyogenes infections, do not readily permeate mammalian cells. There is growing evidence that the ability of streptococci to enter host cells contributes to the frequent failure of antibiotics to eradicate the organism from infected individuals. Recent studies have suggested that host cell entry requires the formation of a complex of a bacterial fibronectin (Fn) binding protein (e.g., M1 protein or protein F1/SfbI), human Fn, and the epithelial cell Fn receptor, integrin alpha5beta1. We report here that a low molecular weight, nonpeptide antagonist of integrin alpha5beta1, SJ755, can inhibit internalization of streptococci by primary human tonsillar epithelial cells and immortalized human epithelial (A549) cells, thus increasing the extent of bacterial killing by antibiotics. SJ755 blocked Fn binding by human tonsillar epithelial and A549 cells, suggesting that integrin alpha5beta1 is the major Fn receptor expressed by both cell types. SJ755 did not affect Fn binding by purified M1 protein or M1(+) bacteria. Purified M1 protein failed to associate with integrin alpha5beta1 unless the integrin had been prebound by Fn. Also, SJ755 blocked formation of alpha5beta1-Fn-M1 complexes in vitro. These results support the previous proposal that Fn functions as a molecular bridge between M1 protein and integrin alpha5beta1. Furthermore, these results suggest that integrin antagonists may enhance the efficacy of antibiotics in treatment of S. pyogenes infections.
