The BaSICS (Baby Skin Integrity Comparison Survey) study : a prospective experimental study using maternal observations to report the effect of baby wipes on the incidence of irritant diaper dermatitis in infants, from birth to eight weeks of age

Background Baby wipes have been shown to be safe and effective in maintaining skin integrity when compared to the use of water alone. However, no previous study has compared different formulations of wipe. The aim of the BaSICS study was to identify any differences in incidence of irritant diaper dermatitis (IDD) in infants assigned to three different brands of wipe, all marketed as suitable for neonates, but which contained varying numbers of ingredients. Methods Women were recruited during the prenatal period. Participants were randomly assigned to receive one of three brands of wipe for use during the first eight weeks following childbirth. All participants received the same nappies. Participants reported their infant’s skin integrity on a scale of 1 to 5 daily using a bespoke smartphone application. Analysis of effect of brand on clinically significant IDD (score 3 or more) incidence was conducted using a negative binomial generalised linear model, controlling for possible confounders at baseline. Analysts were blind to brand of wipe. Results Of 737 women enrolled, 15 were excluded (admitted to neonatal intensive care, premature or other infant health issues). Of the 722 eligible babies, 698 (97%) remained in the study for the full 8-week duration, 24.6% of whom had IDD at some point during the study. Mothers using the brand with the fewest ingredients reported fewer days of clinically significant nappy rash (score≥3) than participants using the two other brands (p=0.002 and p<0.001). Severe IDD (grades 4 and 5) was rare (2.4%). Conclusions Rarity of severe IDD suggested that sensitive formula baby wipes are safe when used in cleansing babies from birth to eight weeks during nappy changes. The brand with fewest ingredients had significantly fewer days of clinically significant IDD. Daily observations recorded on a smartphone application proved to be a highly acceptable method of obtaining real-time data on IDD

698 mothers and babies, 38 390 nappy changes : what did we learn?

Background Several industry funded studies between 2001–2018 have compared the use of a single brand of baby wipes to cleansing with water and either cloth or cotton wool during nappy changes. All of these studies found that wipes were safe and effective from birth. Recommendations from these studies have included the need for brand or formula comparison but to date, no previous study has done this. Aims The ‘Baby skin integrity comparison survey’ (BaSICS) study was designed to compare three brands of baby wipes to determine if there was any difference in the incidence of irritant diaper dermatitis (IDD or nappy rash) during the first eight weeks of life. Methods Mothers who were allocated to a single brand of nappy but divided into three baby wipe allocation groups, collected and reported survey data on infant skin integrity during one nappy change daily with the use of a user-friendly smartphone application. Findings All brands of wipes were acceptable to mothers and safe and effective when cleaning during nappy changes. The brand containing the fewest ingredients showed a clinically significant advantage of fewer incidents of rash than the other two brands. Conclusion This study demonstrated that wipe formulation is a significant factor in prevention or reduction of IDD during the first eight weeks of life

The BaSICS (Baby Skin Integrity Comparison Survey) study: A prospective experimental study using maternal observations to report the effect of baby wipes on the incidence of irritant diaper dermatitis in infants, from birth to eight weeks of age

Background: Baby wipes have been shown to be safe and effective in maintaining skin integrity when compared to the use of water alone. However, no previous study has compared different formulations of wipe. The aim of the BaSICS study was to identify any differences in incidence of irritant diaper dermatitis (IDD) in infants assigned to three different brands of wipe, all marketed as suitable for neonates, but which contained varying numbers of ingredients. Methods: Women were recruited during the prenatal period. Participants were randomly assigned to receive one of three brands of wipe for use during the first eight weeks following childbirth. All participants received the same nappies. Participants reported their infant's skin integrity on a scale of 1–5 daily using a bespoke smartphone application. Analysis of effect of brand on clinically significant IDD (score 3 or more) incidence was conducted using a negative binomial generalised linear model, controlling for possible confounders at baseline. Analysts were blind to brand of wipe. Results: Of 737 women enrolled, 15 were excluded (admitted to neonatal intensive care, premature or other infant health issues).

Severe IDD (grades 4 and 5) was rare (2.4%). Conclusions: Rarity of severe IDD suggested that sensitive formula baby wipes are safe when used in cleansing babies from birth to eight weeks during nappy changes. The brand with fewest ingredients had significantly fewer days of clinically significant IDD. Daily observations recorded on a smartphone application proved to be a highly acceptable method of obtaining real-time data on IDD. Clinical Trial registration: This study was not designed or registered as a clinical trial as no intervention in normal patterns of infant care took place. Mothers who had already decided to use disposable nappies and a baby wipe product agreed to observe and report on their infants’ skin condition; in return they received a 9-week supply of free nappies and wipes

The De Jong Gierveld short scales for emotional and social loneliness: tested on data from 7 countries in the UN generations and gender surveys

Loneliness concerns the subjective evaluation of the situation individuals are involved in, characterized either by a number of relationships with friends and colleagues which is smaller than is considered desirable (social loneliness), as well as situations where the intimacy in confidant relationships one wishes for has not been realized (emotional loneliness). To identify people who are lonely direct questions are not sufficient; loneliness scales are preferred. In this article, the quality of the three-item scale for emotional loneliness and the three-item scale for social loneliness has been investigated for use in the following countries participating in the United Nations “Generations and Gender Surveys”: France, Germany, the Netherlands, Russia, Bulgaria, Georgia, and Japan. Sample sizes for the 7 countries varied between 8,158 and 12,828. Translations of the De Jong Gierveld loneliness scale have been tested using reliability and validity tests including a confirmatory factor analysis to test the two-dimensional structure of loneliness. Test outcomes indicated for each of the countries under investigation reliable and valid scales for emotional and social loneliness, respectively

Methods for Analyzing the Role of DNA Methylation and Chromatin Structure in Regulating T Lymphocyte Gene Expression

Chromatin structure, determined in part by DNA methylation, is established during differentiation and prevents expression of genes unnecessary for the function of a given cell type. We reported that DNA methylation and chromatin structure contributes to lymphoid-specific ITGAL (CD11a) and PRF1 (perforin) expression. We used bisulfite sequencing to compare methylation patterns in the ITGAL promoter and 5' flanking region of T cells and fibroblasts, and in the PRF1 promoter and upstream enhancer of CD4+ and CD8+ T cells with fibroblasts. The effects of methylation on promoter function were tested using regional methylation of reporter constructs, and confirmed by DNA methyltransferase inhibition. The relationship between DNA methylation and chromatin structure was analyzed by DNaseI hypersensitivity. Herein we described the methods and results in greater detail
