This study examined whether calorie intake during the first week of life influences the risk of bronchopulmonary dysplasia (BPD) in extremely preterm infants. The study reviewed 262 extremely preterm infants less than 29 weeks gestation. It found that infants who developed BPD had similar fluid intake in the first week as infants without BPD. However, BPD was associated with a trend toward reduced cumulative protein intake in the first week. Additionally, taking longer to reach full feed was associated with an increased risk of developing BPD.

Association between Bronchial asthma and Allergic Rhinitis: A Cross-sectional...International Multispeciality Journal of Health
Abstract— Bronchial Asthma is a public health problem in childhood. Allergic Rhinitis (AR) is a very common co-morbidity with Bronchial Asthma. So this study was conducted on 250 Primary School Children to find prevalence of Bronchial asthma and Allergic Rhinitis and their association. It was observed from this study that 17.2% of children were having Bronchial asthma and 20.4% were found to have allergic Rhinitis. Co morbidity of Bronchial Asthma with Allergic Rhinitis was observed in 11.6 % of these cases. It was also observed that Bronchial Asthma was observed significantly more in males than females and children of walled city than outer city. So it was concluded form this study that chances of occurring Allergic Rhinitis is significantly more with Bronchial Asthma than the chances of Bronchial Asthma with Allergic RhinitisProbiotic lgg no benefit in infant allergy
This study examined the efficacy of the probiotic Lactobacillus GG in reducing allergic sensitization and asthma in 131 infants at risk. The infants were randomly assigned to receive either LGG or a placebo for 6 months. The study found no significant differences in atopic dermatitis or asthma-related events between the two groups. However, in subgroups sensitized to food or aeroallergens, IgE levels specific to aeroallergens were significantly lower after treatment with LGG. While supplementation was well-tolerated, some studies have found probiotic groups need more symptomatic drug treatment compared to placebo. Further research is still needed to understand long-term benefits and risks.

Breastfeeding Does Not Increase The Risk Of Asthma
Breastfeeding for 4 months or less does not significantly increase the risk of asthma in children at 14 years according to a study of 4964 children. The study found similar rates of asthma whether children were breastfed for 4 months or less or not breastfed after controlling for potential confounding factors like maternal asthma. There was no association found between duration of breastfeeding and reported asthma symptoms, medication use, school days missed, or hospital admissions related to asthma. The study provides evidence that breastfeeding does not impact the prevalence of asthma in late childhood.
Article on the preterm lung and airway
This document summarizes research on preterm lung development and injury. It discusses how improved neonatal care over the past 40-50 years has increased survival rates for preterm infants but also led to higher rates of bronchopulmonary dysplasia (BPD). Recent research focuses on minimizing initial oxygen exposure and aggressive ventilation to reduce lung injury during the transition from fetal to neonatal life. New therapies also aim to address the pro-inflammatory component of BPD. Understanding the long-term respiratory effects in preterm survivors remains important.

This document summarizes several studies on factors related to bronchopulmonary dysplasia (BPD) in preterm infants. One study found that maternal smoking during pregnancy doubled the odds of BPD in infants, and was also associated with prolonged ventilation and late respiratory disease. Another study found that endothelial cell dysfunction in umbilical vein cells was associated with BPD or death in extremely preterm infants. A third study found that infants treated with caffeine in the neonatal period had better lung function at 11 years of age compared to placebo, mediated by caffeine's ability to reduce rates of BPD.

Bronchopulmonary dysplasia (BPD) was first described in 1967 and characterized by prominent airway injury and fibrosis. With advances in care, "old BPD" is now rare. "New BPD" is characterized by arrested lung development in extremely preterm infants and has multiple risk factors including prematurity, genetic factors, infection/inflammation, mechanical ventilation, oxygen toxicity, and malnutrition. Prevention focuses on strategies like antenatal steroids, gentle ventilation, targeting lower oxygen saturations, fluid restriction, and nutrition. Management includes pulmonary vasodilators, diuretics, bronchodilators, and inhaled corticosteroids, though evidence for many therapies is limited. BPD is associated with
Bronchiolitis in children
Bronchiolitis is caused by viral infections, most commonly respiratory syncytial virus (RSV). It involves inflammation of the small airways (bronchioles) and is most common in children under 1 year old. Symptoms include cough, wheezing, difficulty breathing and feeding. While most cases are mild and self-limiting, some children require hospitalization for severe respiratory distress. Treatment is supportive with oxygen supplementation as needed. Antibiotics and other medications are not effective as bronchiolitis is a viral illness.
Exclusive Breastfeeding Reduces Acute Respiratory Infection And Diarrhea
This study examined the relationship between breastfeeding practices and infant mortality in Dhaka, Bangladesh. The researchers followed over 1600 infants from birth to 12 months. They found that exclusive breastfeeding declined from 53% at 1 month to 5% at 6 months. Partial or no breastfeeding was associated with a 2-3 times higher risk of infant death from all causes, acute respiratory infection (ARI), and diarrhea compared to exclusive breastfeeding. The study suggests that exclusive breastfeeding in early infancy reduces infant mortality, particularly from ARI and diarrhea.

Recent Advances in of BREAST FEEDING : Dr Sharda Jain
This document discusses the importance of breastfeeding and providing human milk to newborns within the first hour after birth, known as the "Golden Hour." It recommends exclusively breastfeeding or providing pasteurized donor human milk during this critical period, as formula feeds are not recommended. Initiating feeding within the Golden Hour provides significant health benefits and can reduce neonatal mortality rates. Challenges to early feeding include caesarean deliveries and ensuring babies receive an adequate volume of milk. New products like NeoLact 70 Prime aim to provide short term human milk-based nutrition for all newborns during the Golden Hour to promote gut health and a smooth transition to breastfeeding.

This document presents a debate on whether preschool children experiencing acute wheezing episodes should be treated with oral corticosteroids (OCS). The pro side argues that many preschool children with recurrent wheezing develop atopic disease and sensitization which predicts increased risk of asthma and response to OCS therapy. Studies have shown heterogeneity in design and populations making it difficult to make definitive recommendations against OCS use. The con side argues that most studies have not demonstrated beneficial effects of OCS for acute wheezing in preschool children. Repeated OCS bursts may also be associated with adverse effects. Both sides agree more efficacy trials are needed targeting phenotypes likely to respond to OCS.

It describes the case of an infant born with micrognathia, tongue retraction, and airway obstruction consistent with Pierre Robin syndrome. The syndrome can be genetic in origin but was not associated with any other anomalies in this case. Management involved a multidisciplinary team and initial tongue-lip adhesion surgery to relieve respiratory distress, followed later by mandibular distraction osteogenesis. Non-surgical positioning and nasopharyngeal tubes are often successful initially in many cases. A small subset requires more invasive procedures like tongue-lip adhesion or tracheotomy. Early feeding via nasogastric tube can also help with weight gain and reducing calorie needs in these

Fetal exposure to bisphenol a as risk factor for the childhood asthma
This study investigated the effects of perinatal bisphenol A (BPA) exposure on the development of allergic asthma using a mouse model. The researchers found that prenatal BPA exposure, but not solely postnatal exposure from breast milk, enhanced susceptibility to developing asthma-like symptoms in response to allergen sensitization. Gene expression analysis revealed delayed expression of the BPA-metabolizing enzyme Ugt2b1 in mouse fetuses and newborns, which may explain their enhanced susceptibility to the estrogenic effects of BPA crossing the placenta. The critical window of enhanced susceptibility was found to be prenatal exposure.
POSTER Influence of breastfeeding on infant allergy development
This document discusses the influence of breastfeeding on infant allergy development. It finds that exclusive breastfeeding for 6 months and any breastfeeding for 1 year is most beneficial for decreasing food allergy risk. Components in breast milk like food antigens, antimicrobial peptides, and cytokines provide immunoprotective effects that help infants digest potentially allergenic foods. The duration of breastfeeding is correlated with decreased infant allergy development.
Folic Acid Awareness A Crucial Step Towards Preventing Anencephaly
This case report aims to shed light on the critical importance of folic acid intake not only during pregnancy but also before conception. The focus is on preventing anencephaly, a devastating neural tube defect that can be avoided through proactive measures such as incorporating folic acid rich foods into ones diet and supplementation. Anencephaly is a congenital condition that cannot be cured, making prevention the key to sparing both infants and mothers from the emotional and physical burdens associated with this tragic disorder. The report emphasizes the need for increased awareness and education about the role of folic acid in prenatal health to empower individuals in taking a small yet impactful step towards a healthier future.

The Evidence For Breastfeeding
Professor Forsyth studied the health outcomes of 543 children from lower and higher socioeconomic groups. He found that (1) in the lower socioeconomic group, breastfed children had similar or significantly better health outcomes than formula-fed children, even compared to formula-fed children in the higher socioeconomic group. Subsequent studies discussed in the document found that (2) exclusive breastfeeding for at least 15 weeks reduced respiratory illness and that (3) one month of exclusive breastfeeding conferred protection against allergies and respiratory issues into childhood and adolescence. Overall, the document reviews extensive evidence that breastfeeding leads to improved health outcomes related to infectious disease, cognitive development, cardiovascular risk factors, obesity, and diabetes among others.
Asthma Prevalence in HK Nurture, Not Nature
Asthma is a common chronic lung disease, which affects approximately 120,000 children in Hongkong. Statistics showed that 40% of this population require outpatient specialty care from time to time. Patients who are hospitalized represent 15% of children admitted to medical facilities. In recent years, various studies proved that there is an increasing trend in the number of asthma cases.

This document discusses the role of maternal nutrition in the development of the fetal cardiovascular system. It begins by outlining Barker's hypothesis that heart disease may originate during fetal development due to nutritional inadequacies altering cardiac physiology and increasing risk of cardiovascular disease later in life. It then examines how nutrition affects fetal development through the placenta and fetal programming, discussing specific nutrients' impacts on the developing heart and gene expression changes from maternal nutrient restriction. The goal is to understand these relationships to improve fetal nutrition and prevent cardiovascular disease.
DELAYED CLAMPING OF THE UMBILICAL CORD TO REDUCE INFANT ANAEMIA
Delayed clamping of the umbilical cord is recommended by the WHO to reduce infant anaemia. Delaying clamping for 1-3 minutes allows blood from the placenta to pass to the infant, increasing their iron stores. This reduces anaemia and related health issues. While some have concerns delayed clamping may increase risks like jaundice, studies show no increased risks for babies. Delayed clamping provides benefits to both full-term and preterm infants like reduced need for blood transfusions. The WHO recommends delayed clamping be integrated into standard newborn and postpartum care.

The document discusses several studies on bronchiolitis. It finds that living near a major highway is associated with a 6% increased risk of hospitalization for bronchiolitis. Cigarette smoke exposure decreases apoptosis and increases viral load during RSV infection. High cord blood levels of IL-6 and IL-8 are associated with more severe bronchiolitis. Certain surfactant protein polymorphisms are also linked to increased disease severity and hospitalization risk. A recent study suggests nasal wash lactate dehydrogenase levels may help predict bronchiolitis severity and hospitalization need.

This study analyzed data from over 15,000 infants in the UK Millennium Cohort Study to examine the relationship between breastfeeding and hospitalization for diarrhea and respiratory infections in the first 8 months of life. The results showed that exclusive breastfeeding, compared to no breastfeeding, was associated with a lower risk of hospitalization for both diarrhea and respiratory infections after adjusting for various confounding factors. Partial breastfeeding also showed a protective effect, but it was weaker than exclusive breastfeeding. The protective effects of breastfeeding decreased after breastfeeding cessation. The study suggests that increased rates of exclusive and prolonged breastfeeding could significantly reduce hospitalizations in the UK.

Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid

JAMES WEBB STUDY THE MASSIVE BLACK HOLE SEEDS
The pathway(s) to seeding the massive black holes (MBHs) that exist at the heart of galaxies in the present and distant Universe remains an unsolved problem. Here we categorise, describe and quantitatively discuss the formation pathways of both light and heavy seeds. We emphasise that the most recent computational models suggest that rather than a bimodal-like mass spectrum between light and heavy seeds with light at one end and heavy at the other that instead a continuum exists. Light seeds being more ubiquitous and the heavier seeds becoming less and less abundant due the rarer environmental conditions required for their formation. We therefore examine the different mechanisms that give rise to different seed mass spectrums. We show how and why the mechanisms that produce the heaviest seeds are also among the rarest events in the Universe and are hence extremely unlikely to be the seeds for the vast majority of the MBH population. We quantify, within the limits of the current large uncertainties in the seeding processes, the expected number densities of the seed mass spectrum. We argue that light seeds must be at least 103 to 105 times more numerous than heavy seeds to explain the MBH population as a whole. Based on our current understanding of the seed population this makes heavy seeds (Mseed > 103 M⊙) a significantly more likely pathway given that heavy seeds have an abundance pattern than is close to and likely in excess of 10−4 compared to light seeds. Finally, we examine the current state-of-the-art in numerical calculations and recent observations and plot a path forward for near-future advances in both domains.
Evidence of Jet Activity from the Secondary Black Hole in the OJ 287 Binary S...
Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.

The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

- 3. Abstract Aim: To examine whether caloric intake during the fi rst week of age infl uences the risk of Bronchopulmonary Dysplasia (BPD) in extremely preterm infants. Methods: In this retrospective cohort study, all infants born with gestational age < 29 weeks over 30 months period were eligible for the study. Infants with major congenital anomalies and those who died before 36 weeks postmenstrual age were excluded. We compared the nutritional characteristics between infants who developed BPD and those without BPD. Results: Of the 262 eligible infants, 233 were included for the study. A total of 125 infants developed BPD. Infants with BPD had similar fl uid intake in the fi rst week of life to other infants with no BPD. After adjusting for gestational age, severity of illness and PDA, BPD was associated a trend towards reduced cumulative protein intake in the fi rst week of life (OR=0.91 95% CI: 0.81-1.01). Increase time to reach full feed is associated with increased risk of BPD (OR=1.03; 95%CI: 1.00 - 1.06).
