Questions related to Infants
My study setting has 30 villages
First step: I included all the 30 villages in my survey
Second step: in each village 10 households with infants 12-23 months were randomly recruited using a random walk method
Question1: If I include all the 30 villages, is it still a two-stage cluster sampling method?
Question 2: To what extent does including the same number of participants from each village affect the representativeness of my sample?
Appreciate someone’s insight on my query. I am extracting vitamin B2 (riboflavin) and FMN analytes from infant milk formula and identifying/analyzing it in reverse phase liquid chromatography using linear regression. We run multiple injections of pure working standards (WS’s) before samples and quality controls (QCs) in between samples of riboflavin and FMN to check if the conditions are same and consistent throughout the run and whatever results we get are true results. I am facing a problem in which QC’s of FMN analyte peak area start getting increase as the injections reach to the end of the sequence. It is the same vial, same position in the autosampler but peak area gets increased. Does anyone faced the same type of issue?
New infant acquired methemoglobinemia case data, found for an upcoming book, show infant morbidity and mortality down to about 1 ppm nitrate-N. USEPA missed these data sets when they calculated or multiply reaffirmed the basis for the existing 10 ppm nitrate-N drinking water standard.
Based on this finding and others you might have, what should revised standard concentrations for nitrate-N and derived nitrite-N be and how would you perform the calculation?
Are there any studies or publications regarding the optimal duration of a nap, for infants to regain their best performance/homeostasis?
I hope my message finds you well.
I'm doing a diagnostic study to find out the most accurate method to diagnose fever in febrile infants. I'm using axillary temperature mesuramtent as an index test and rectal temperature as a reference test. The total population size is 201. The number of infants diagnosed using axillary method were 159, whereas rectal temperature was positive for every subject. The number of infants who had normal temperature using axillary method and had fever using rectal method were 36. How can I calculate the sensitivity and specificity? I find it confusion a bit because I don't seem to understand how to allocate the numbers in the cross-tab.
Thank you for your cooperation!
Are there any references for Estimated Average Requirement (for minerals and vitamins) of infants less than 6 months?
A 10 month premature baby is not able to eat on his own. It had a CDH surgery right after birth and a re-herniation at 6 months. The smallest amount of food causes choking and vomiting, visible trouble in swallowing (but only the food). The baby is fed through an NG-tube.
- acid reflux excluded
- vascular ring excluded (an esophageal stricture had been suspected)
- another re-herniation excluded
The baby is under a Speech and Language Therapist care. Gastrologists can't find the cause. What are the most common diagnosed problems of CDH babies responsible for feeding difficulties? How to treat them? What should be checked?
I need a set of images of emotional faces (angry or sad; neutral; happy) of infants. I would like to frontally present these faces on a screen in a computer experiment. If infant images were matched in size, luminance, position, etc, with other images of adults, it would be great! Yhank you
I have analysed infant milk powder with Raman microscopy. However, the Raman shift (cm-1) is very high and it's not what I was looking for. Usually the Raman shifts of milk powder is between 400 cm-1 and 4000 cm-1 and this is beyond those number. What went wrong? I am also sure that the unit is cm-1 and not something else.
I am trying to measure the bilirubin concentration in the infant rats’ tissue brain. However, I am unsure whether I can use Bil - Hall’s bilirubin staining method as most previous studies have been done on the liver and kidney tissues.
What will be the prognosis of tuberous sclerosis in an infant who got diagnosis of tuberous sclerosis just at the age of 2-3 months through scan.
In our recent study comparing the developmental status among premature babies versus term babies, we end up with this conclusion " Half of the children had developmental delay in our sample from rural Rwanda. Preterm and/or LBW infants were more likely to have developmental delay, and the main predictor of developmental delay was stunting, with high rates of stunting observed also in term/NBW infants. Interventions to reduce undernutrition and prevent prematurity and LBW, alongside investments to promote early stimulation for optimal development, are needed if gains in addressing developmental delay are to be made."
So in the order to help our study to have an impact on the field I would like to know which early child stimulations methods to be use successfully in middle in come countries especially in Rwanda.
which one is the updated and validated questionnaire for measuring infant and young child (6-24month) feeding practice without taking interview? is there any that measured in likert scale or other rating scale?
I am trying to analyze some questions for infants. I want to find some questionnairs used by birth cohort study or some commonly uesd questionnaires of infants.
I am curious about the use of art therapy to encourage mirroring and bonding with mother and infants dyads. I can think of prompts for the mother that are easier done without an infant but nothing she could do safely with her baby. Any suggestions?
Hi everyone, I came across something strange in HPV PCR of an infant. The specimen was CSF and the positive and negative control didn't have any problem but I'm not sure about the positive band which have been detected on agarose gel.
I am processing infant kinetic data. However, the kinetic graphs I obtain seem a bit noisy. I wonder which filter are recommended to use in Vicon Nexus for the infant kinetic data (.MOT file)?
1. Which frequency should I use (0.01, 10, 50, 100, 200 or 300 Hz)?
2. Is it 2nd order (with lag) or 4th order (zero lag)?
Ever since Groningen Protocol was regulated in 2004 and proposed as a medical protocol by Dr. Eduard Verhagen- professor of pediatrics and medical director of University of Medical Center Groningen- as a purpose to extend the existing legality of euthanasia to newborns (and late-term pregnancies), Verhagen addresses in Pediatricians call for a nationwide protocol for the ending of life of unbearably and incurably suffering newborns. “ This is a subject that nobody likes to acknowledge, let alone discuss. But, it is in the interest of newborns who have to endure unbearable suffering that we draw up a nationwide protocol that allows each pediatrician to treat this delicate question with due care, knowing that they followed the criteria.” (The University Medical Center, 2004). The most important condition is euthanasia is only to be used if the baby is experiencing extreme suffering (pain) that no treatment can alleviate, in which the protocol is invoked purely as a final act of mercy. This means that ethical issues of euthanizing severely disabled infants have been put in the debate in regards to the morality of euthanasia if it’s performed on fragile subject such as infants. This has raised many to question of to what extent should euthanasia be performed on infants and newborns with severe conditions such as spina bifida or is it “too damaged’’ and “ immoral’’ for society to advocate this practice that originated from Northwestern Europe. The topic has induced many debates and questions that revolve around euthanasia as a medical option to help relieve pain for infants and newborns
I want to find out respiration rate for the infants and adults. The range for rate is 0 to 60.
I have written algo but that is working on slow rate only. For High rate, I am getting slow output only. Please suggest me any method to findout output for the whole range.
I’m really a novice in the field and just started to learn to use the EEGlab. I’m writing because I’d like to run a power/frequency analysis on the data I have – and I’ve got a question.
The data was collected from 9-month-old infants using the EGI system, HydroCel Geodesic Sensor Net with 128 channels. We’re interested in brain activities occurring during a 5-sec long interval. Each infant did 7 to 9 trials (i.e. each infant gave us 7-9 intervals to analyse), which seems very small as a number of trials but it’s not very unusual for infant EEG studies + the study is a pilot.
I’ve been using a NetStation to pre-process EEG so I thought it’d be easier to segment the data, do the artefact detection and replace bad channels identified, and then import these epoched data into the EEG lab to do the FFT (or other transformation methods for the power analysis). But I was advised a few times to use the EEG lab from the beginning of the preprocessing (i.e. epoching, artefact detection and interpolation). Is there any difference between these two? If so, what is the difference and what may be the pros and cons of each method?
I hope this makes sense – but please get in touch if you can help me with this and/or need more information.
Thank you very much in advance, and I hope you have a lovely day.

I'm working with infants and want to track their lip movements. My concern is that they won't accept any marker on their lips. I^ve never used any motion capture system but plan purchasing one in the context of my research. Any suggesting is very welcome.
Thanks for your assistance...
Please mention only recent evidences supporting your view and what is today the best practice we can implement to these children...please do not mention all aspects...take position...
WHO RECOMMENDATION IS as :
"" The Committee recognizes the difficulty in identifying infants infected with HIV at birth in settings where diagnostic and treatment services for mothers and infants are limited. In such situations, BCG vaccination should continue to be given at birth to all infants regardless of HIV exposure, especially considering the high endemicity of tuberculosis in populations with high HIV prevalence. Close follow up of infants known to be born to HIV-infected mothers and who received BCG at birth is recommended in order to provide early identification and treatment of any BCG-related complication. In settings with adequate HIV services that could allow for early identification and administration of antiretroviral therapy to HIV-infected children, consideration should be given to delaying BCG vaccination in infants born to mothers known to be infected with HIV until these infants are confirmed to be HIV negative.""
what is a practical clinical approach in such cases?? advice to mothers....
Some times we want to conduct a reliability study on some diagnostic modality for a specific disease but the gold standard for the diagnosis of that disease is either invasive procedure or surgery. which is not justified to be performed on normal individuals (control group). In such a case is it justified to take control group as negative of the gold standard?
We want to diagnose Infantile Hypertrophoid pyloric stenosis (IHPS) with the help of ultrasound but the gold standard for its diagnosis is surgery. If we perform Ultrasound of 50-infants with projectile vomiting and the sonographic findings of 40 of them are likely for IHPS and 10 for normal. But after surgery (Gold-Standard) 38- were confirmed as IHPS but 2 were false positive. Now we want to perform ultrasound of 50-normal (control). Is it justified to put all the 50 normal infant as True negative and false positive as 0 of the gold Standard, To perform chi-Square statistics?
I am hoping to analyze HR collected and was looking for advice on methods for analyzing HR and linking it to specific tasks and/or overt behaviours
I am working with groups who do not have a written language and need some research / project info on training people in this community to be supporters of other women in their community on topics related to infant and young child feeding.
The change in the composition of gut microbiota in early infancy has been reported to correlate with the future development of many kinds of diseases such as allergy, inflammatory bowel diseases, or obesity. However, there seem to be few studies on the impact of the change in oral microbiota in early infancy on their health in later life. In adulthood, changes in the oral environment are thought to be linked to diseases like metabolic diseases or vascular diseases. Do you think changes in oral microbiota in infancy can also have a substantial impact on future health similarly to gut microbiota?
I am particularly interested in the model you have created of the infant skeleton, the lower limb region. I am working on a skeletal/biomechanical model of congenital talipes equinovarus (clubfoot deformity) and am investigating what has been done in creating skeletal infant lower limb models. Thank you for your time, I look forward to your response.
Can you recommend me a laboratory to assess cortisol and alfa-amilase in saliva? I am from Chile and I need to determine both biomarkers in infant's saliva. Any information or your experience in this research field can help me to develop my study. Thank you in advance.
The ICRP Publication 101 "Assessing Dose of the Representative Person for the Purpose of Radiation Protection of the Public" defines the deterministic and probabilistic approaches to find the dose of the Representative Person from doses incurred by population members. Are results for members of the group of different ages included in forming the average or the 95th percentile of the dose distribution, or shall they be treated separately? I am not sure, although the example for the probabilistic approach in B.7.2 of ICRP 101 would suggest the first case. Simply put, at the end of the analysis, is there only one Representative Person with one Dose to the Representative Person, or are there Representative Persons for each age group, e.g. Representative Infant (1 y), Representative Child (10 y), Representative Adults (adult).
I would like to ask if you are aware of any tool (Matlab/toolbox, etc.) that calculates the "lag between BOLD time series", as described in the following publications:
Thank you very much.
I stumbled upon a research idea that seems significant and might reduce Shaken Baby incidences. Currently I am not affiliated with a hospital or university to use their IRB for review.
I'm not sure I need an IRB because I'm comparing the outcome of two activities mothers engage in normally with infants.
What are you thoughts?
Do you think acute diarrhea in infants
Affect the development situation
For physical equipment in infected infants?
Usually KD is recom as one of the last option in a child with drug resistent epilepsy (DRE): A new therapeutical point of view should be a new option in a infant?
Some previous studies reported geographical variation in the composition of the gut microbiota in early infancy before weaning. In particular, infants in Scandinavian countries had gut microbiota dominated by bifidobacteria in early infancy, while those in southern European countries didn't.(Nat Rev Gastroenterol Hepatol 2012: 9: 577–89.doi:10.1038/nrgastro.2012.156) Recently we confirmed that Japanese infants also have bifidobacteria dominating microbiota in their guts.
Which factors do you think can be attributed to this similarity in the composition of the gut microbiota between geographically, ethnically, and culturally distant regions?
I have come up with several factors such as nutrition (breast, mixed, or exclusive milk feeding), genetic backgrounds, the gut microbiota of their family members, but none of them seems to answer the question.
I am interested in both observational and self report measures.
i want to work on a child of 3-6 month or above. my main focus is to study speech production of children depending on how fast they assimilate or pick. And the other topic is to make a comparative study of speech production and understanding capacity of children language between 3-9 month. furthermore i intend to see a critical examination of infants assimilation rate of the three major languages in Nigeria.
- low dose ASA is in discussion to increase skin cancer in male adults.
- ASA showed significant decreased thymus-size in animal studies.
- Should we create studies to clear this question ?
Is their any data in neonates or children after longterm low dose ASA in pregnancy?
In Germany we observe an uncritical use of low dose ASA in reproductive medicine and every kind of previous pregnancy complication.
For me is a doubt, if toddlers (1-2 years old) work with the atelierista. I know that in the next stages the atelierista is a important teacher, but infants visit the atelier too?
Our plan is to enroll all babies born in a particular district and follow them up until 1 year old. We expect about 38000 births in the district and about 70 cases. Sample size calculators are giving me a sample size of 1! How do I go about it?
By birth many of the infants are affected by congenital glaucoma. What is the main reason behind this and could this possible to find the symptoms in earlier stage?
I need to buy a portable HRV monitor to assess vagal tone in infants during several experiments.
I am looking for a new device since the one cited in the studies are mostly old.
Thanks a lot
I am a research student at my institute for 6 months and I am going to work on research project entitled "detection of reasons behind infant cry". For this project, I need a database which will have the audio files of crying babies with reasons specified. Are there any such databases available?
I would like to carry out a long-term study on infants (from 3 to 12 months of age). I have invented a simulation: The Infant Learning Environment Program. It puts infants in control of the program from their first interaction with it. Its goal is to simultaneously teach infants to speak, read, and think.
If interested, please read Inventing an Infant Learning Environment that can be downloaded from thinkingbabies.org and Research Gate.
I use a craniometer daily to measure infants with plagiocephaly and/or brachycephaly. It is not easy as infants do not always cooperate, but I think it work well after some training (if using a headband with marks). This weekend I had inexperienced therapists (inexperienced in measuring with craniometer) measuring models of infant head ("home made"), it ought to be rather "easy" as this model heads do not move. However the result was not as good as expected, (I will do it again with better models of heads).
I would like to know about others experience with measuring with craniometer.
Role of ultrasound in developmental dysplasia of the infants hip (DDH) joint very informative and valuable before 6 months infants age.
May I know is there anyone who have experiences on infants (0-4 months of age) saliva collection and analysis who can share? I am wondering what factors should I consider before I choose which kits to go for? Do I really need to use a kit? PM or comment are welcome.
In the NICU population, does dressing and swaddling infants on air mode in an isolette help wean and adjust to open crib better than dressing and not swaddling infants?
I would like to find the guidelines for the indoor air quality parameters such as:
- Relative Humidity
not for adults but for infants.
Are there any references ?
What changes occur when an infant and subsequently child first realize that they are "different" than "you." What might be missing (neurophysiologically) in some autistic spectrum individuals when they refer to themselves as "you"?
Mother's own milk is preferred nutrition for a premature infant. Mother's own milk delivered "fresh" or not ever frozen has been consistently shown to have higher nutritional content and retain more immune-protective factors. However delivering fresh milk to bedside proves to be a systems-based challenge in large units. Some large children's hospitals have processes to routinely freeze all milk upon entry. Does your neonatal intensive care unit consistently deliver fresh milk to your infant when available?
We would like to either calculate CDI for different monthly periods after birth or for period of 1 year after birth for measured POPs concentrations in human milk. Would you recommend to use a traditional risk assessment approach for calculation of CDI, thus “CDI = C x IR x EF x ED / BW x AT” or would you alter the equation in some way? There are articles using just the following equation “CDI = C x IR / BW” however they do not take into account length of exposure and they produce significantly different results.
i am working on infant cry detection system, i want to detect infant cry by facial
expression, so what are features of the image i should extract to do with deep
learning algorithms. how it is done?
I am a health visitor, and get asked about treating sticky eyes in infants a lot. Another practitioner has recommended treating this with baby shampoo. I am not happy to recommend this treatment as i am unaware of any research that supports
We have already reported such a case in an infant. You can find the link in my profile.
I want to measure TEWL in extremely premature infant's nursed in high humidity.
I'm not sure if the existing devices to measure TEWL are accurate in high humidity.
I am looking for research on the experiences of moms of preterm born infants regarding child care in the first year. I would apreciate if you can share or indicate literature on this topic, since I am not finding it. Thanks a lot. Regards
I was wondering if you could help me to understand the score awarded by PEDro to my article on the "blind subjects" criteria. Here is the link to it: http://search.pedro.org.au/search-results/record-detail/37529
Were the infants of the study considered to be blind because the envelopes were opened right immediately before the training session, which was a brief and single one and therefore it unabled them to distinguish between the treatments applied to the other groups? This question is because most of the other articles in which infants' reaching was trained (training over weeks, not in a single session) did not awarded the "blind subjects" criteria. I really would like to understand how that criteria works for infants.
Thank you in advance.
Does anyone know of research that indicates that young infants (i.e., 8-15 weeks) might process adult and other infant faces differently in any way?
I want to start working in a kindergarten and I need some idea to doing some tests about creativity and acting out (discharge, purge) in children, for example, painting.
Microcephaly is a rare side effect in these cases. I need to know exactly how rare.
Dear colleagues, does anyone know an article about bone mineral content (BMC) in newborn and adults (changes through age)? I just found, for example, BMC in lumbar spine of infants, but no comparison to older ages.
Thanks in advance!
I am looking at research on infants ability to speak and whether or not teaching an infant sign-language can help develop their verbal ability.
