Modelling the woven fabric strength using artificial neural network and Taguchi methodologies

Purpose – Jacquard woven fabrics are widely used in various sections of upholstery industry, where mattress cover is one of them. Strength of jacquard woven mattress fabric depends on several factors. The objective of this study is to model the multi‐linear relationship between fibre, yarn and fabric parameters on the strength of fabric using artificial neural network (ANN) and Taguchi design of experiment (TDOE) methodologies.Design/methodology/approach – TDOE was applied to determine the optimum design values and the contribution of each parameter. Robustness (performance) of models is measured by root mean squared error (RMSE). These tools will enable the user to predict the fabric strength from number of given inputs. It also provides the knowledge related to the contribution of fibre, yarn and fabric parameters on fabric strength. Fabrics tested in this study made from different fibre types and max/min level for several fabric and yarn‐related parameters. The models generated with TDOE and ANN method...

A Prospective Crossover Study to Understand Interactions Between the Environment and Symptom Control

National asthma guidelines emphasize symptom control as a function of asthma management, which includes allergen avoidance and medical therapy. This paper describes the impact of environmental mitigation on symptom control, use of short acting beta agonists, hospitalizations and emergency room visits. Patients were enrolled in a randomized, crossover environmental mitigation/education study. Group 1 began active phase at enrollment, switching to inactive phase at six months. Group 2 began inactive phase at enrollment, and active phase at six months. Observations of environment and asthma symptom diaries were collected every 2 weeks. 264 children were enrolled, mean age 6.5 years. Successful reduction of dust antigen, roaches, rodents, carpet and increasing mattress and pillow cover use seen in both groups. For Group 1, decreased nighttime coughing was associated with reduction of furry pets (p 0.008) and roaches (p 0.05) with increase mattress covers (p 0.04); and decreased nighttime wheezing was associated with reduction of furry pets (p 0.08) and increased mattress covers (p 0.01). For Group 2, decreased nighttime cough was associated with reduction of furry pets (p 0.02). Albuterol use was not affected by any trigger. Both groups showed reduction in emergency room (p < 0.0001) and inpatient visits (p 0.0006) as compared to 12 months before enrollment. Nighttime coughing appears to be more sensitive to trigger reduction than nighttime wheezing. Since nighttime wheezing is considered to be more severe than coughing, it may be that children for whom wheezing is their primary symptom, will not respond as quickly to changes in their environment.

A Feather Bed Dictionary: Colonialism and Sexuality

AbstractIn this paper I utilise ‘autoethnography’. In dialogue with my white ancestor's Dr Sidney Spencer Kachalola Broomfield's autobiography Kachalola or the Mighty Hunter (1931), I examine his representation of the black female body in Northern Rhodesia (present day Zambia). Broomfield presents the black female body as decadent, demonised and sexualised, accusing it of conquering white men regardless of education, class and religious affiliation. Firstly, I question how the black female body sexuality and reproduction became site of social, political and racial contest and entanglement and contradictorily also the site of collaboration between white and black men; secondly, I examine the ongoing legacies of Broomfield's representation.

Estimating heart rate and RSA from the mattress‐recorded kinetocardiogram

This article describes a method for extracting heart rate (HR) and respiratory sinus arrhythmia (RSA) from the kinetocardiogram (KCG) recorded from accelerometers embedded in a mattress topper. Validation has been performed via comparison with simultaneously recorded ECG. All-night estimates of HR and RSA magnitude derived from both methods were highly correlated. KCG-derived estimates of HR were slightly lower, and those of RSA magnitude higher, than those derived from ECG. These biases are consistent with the need to constrain KCG estimation to periods free of body movement. Mattress actigraphy represents a zero-burden method of obtaining intensive longitudinal indices of cardiac status.

Impact of environmental exposures on asthma control in pregnancy

JUDETTE LOUIS, NICHD MFMU Network, Bethesda, Maryland OBJECTIVE: To evaluate the impact of avoidance of environmental exposures on asthma control and treatment in pregnancy. STUDY DESIGN: This is a secondary analysis of a multicenter; prospective, observational cohort study conducted over 4 years at 16 academic hospital centers. The NAEPP classification was used to stratify patients by asthma severity. Environmental exposures included household smoking, pets, and use of a mattress cover. Indices of asthma control included percentage of symptomatic days and nights, activity restriction, and sleep disturbance. Indices of treatment included number of unscheduled visits, hospital admissions, asthma exacerbations, and use of steroids. Data were analyzed by chi-square, Wilcoxon rank sum and Cochran-Armitage trend test where appropriate. P!0.05 was significant. RESULTS: There were 1,812 asthmatics, 50% (906), were mild, 47% (851) were moderate and 3% (55) were severe asthmatics. Severe asthmatics that could identify 1 or R 2 asthma triggers had a lower rate of symptomatic days compared to those who did not know their triggers. (22.9% and 26.6% vs. 48.6%, p = 0.04) They also had less nights of sleep disturbance (7.3% and 19.2% vs. 28.8%, p = 0.02), were less likely to have an unscheduled visit (21.4% and 0.0% vs. 36.4%, p = 0.03 for trend) and less likely to have an asthma exacerbation during pregnancy (50% and 50% vs. 81.8%, p = 0.02 for trend). This association was not evident for mild and moderate asthmatics. In mild and moderate asthmatics, use of a mattress cover was associated with a decrease in sleep disturbance and fur bearing pets were associated with an increase in symptomatic days. Among mild and moderate asthmatics, avoidance of environmental exposures was not associated with any treatment indices. CONCLUSION: Avoidance of asthma triggers may improve daily symptoms and need for treatment for severe asthmatics. The findings are not as consistent for mild and moderate asthmatics.

Comparison of Pressure Relief Properties of Operating Room Surfaces

There are many operating room (OR) mattresspads and overlay surfaces; however, little empir-ical evidence is available regarding the pressure-reducing characteristics of these various surfaces.Foam and gel mattresses, with and withoutviscoelastic overlays, have been reported to reducethe skin interface pressure more effectively thanthe standard OR mattress pad [1–4]. Defloor andDeSchuijmer [5] reported that although the foammattress and the gel mattress had little pressure-reducing properties, the polyurethane and thepolyethermattresssignificantly(P!.001)reducedinterface pressures. However, none of the OR sur-faces studied (eg, polyurethane, polyether, gelmattress, foam mattress, standard OR mattress)reduced the pressures to less than 32 mm Hg. Itis relatively routine to use foam padding and geloverlays with the impression that padding the pa-tientrelievespressureandpreventspressureulcers.Therefore, this performance improvement studywas undertaken to describe the peak skin interfacepressuresinthespineandlateralpositionsonthreecommonly used OR surfaces.A key issue when positioning surgical patientsis the prevention of skin injury. Ischemic injuryand the potential development of pressure ulcersis a concern for any patient who remains in oneposition for prolonged periods. Although theincidence of pressure ulcers in acute care popula-tions is between 3% and 29%, the incidence forsurgical patients is higher, between 12% and 35%[6–8].This increased incidence is due in part to thecombined extended period of uninterrupted pres-sure and the forced immobility during surgicalprocedures in conjunction with the effects of anes-thesia [9].Prolonged exposure of the skin and underlyingtissues to high interface pressure or exposure tolow pressure over extended periods may predis-pose the patient to ischemic injury. Ischemicinjury occurs with increased frequency overweight-bearing bony prominences covered byskin and a small amount of muscle and sub-cutaneous tissue. In the supine position, morevulnerable sites include the occiput, scapula,olecranon process, sacrum, ischial tuberosities,and the calcaneous. In the lateral position, theear, acromion process, iliac crest, greater trochan-ter, lateral knee, and malleolus are the bonyprominences of concern. For the purpose of thisproject, the peak interface pressures over thebony prominences (occiput, sacrum, greater tro-chanter, and heels) were of interest.External pressure on tissues at capillary in-terface pressures greater than 32 mm Hg mayocclude capillary blood flow causing diminishedtissue perfusion and an ischemic injury that maylater manifest as a pressure ulcer [10]. The dura-tion of pressure is thought to be more of a contrib-uting factor than the intensity of the pressure,with 2 hours or longer associated with the devel-opment of ischemic injury.

Growth and survival of bacteria implicated in sudden infant death syndrome on cot mattress materials

To compare growth and survival of selected bacteria implicated in sudden infant death syndrome (SIDS) on cot mattress polyurethane (PU) inner-foams and on different types of cot mattress cover materials. Escherichia coli, Staphylococcus aureus or Streptococcus pyogenes were inoculated onto swatches of new-unused cot mattress PU inner-foam and onto three types of cot mattress covers (polyvinyl chloride, cotton and polyester). The influence of inoculation cell density, relative humidity (RH) and temperature of incubation on survival was assessed by recovery of cells in 0.85% NaCl, with viable cell enumeration by plate counting on selective and differential media. Utilization of carbon and nitrogen sources within cot mattress PU was assessed by following growth on aqueous leachate from PU, and by colorimetric determination of aromatic amines. Good survival capability (>206 d) was shown by all three test species on PU inner-foam and on polyester mattress cover at high RH (75%), but only by Staph. aureus on PU at low RH (25%). Aqueous soluble material from PU foam supports bacterial growth; removal of aromatic amines from aqueous leachate from PU accompanies growth of Staph. aureus. Staphylococcus aureus has good survival capability on cot mattress PU foam, even at low RH. Soluble material within PU can serve as carbon and nitrogen sources for bacterial growth. Prolonged survival of Staph. aureus on PU at low RH could explain, in the context of the common bacterial toxins hypothesis, an increased risk of SIDS associated with used infant mattresses.

The Biologic Effects of Grounding the Human Body During Sleep as Measured by Cortisol Levels and Subjective Reporting of Sleep, Pain, and Stress

Diurnal cortisol secretion levels were measured and circadian cortisol profiles were evaluated in a pilot study conducted to test the hypothesis that grounding the human body to earth during sleep will result in quantifiable changes in cortisol. It was also hypothesized that grounding the human body would result in changes in sleep, pain, and stress (anxiety, depression, irritability), as measured by subjective reporting. Twelve (12) subjects with complaints of sleep dysfunction, pain, and stress were grounded to earth during sleep for 8 weeks in their own beds using a conductive mattress pad. Saliva tests were administered to establish pregrounding baseline cortisol levels. Levels were obtained at 4-hour intervals for a 24-hour period to determine the circadian cortisol profile. Cortisol testing was repeated at week 6. Subjective symptoms of sleep dysfunction, pain, and stress were reported daily throughout the 8-week test period. Measurable improvements in diurnal cortisol profiles were observed, with cortisol levels significantly reduced during night-time sleep. Subjects' 24-hour circadian cortisol profiles showed a trend toward normalization. Subjectively reported symptoms, including sleep dysfunction, pain, and stress, were reduced or eliminated in nearly all subjects. Results indicate that grounding the human body to earth ("earthing") during sleep reduces night-time levels of cortisol and resynchronizes cortisol hormone secretion more in alignment with the natural 24-hour circadian rhythm profile. Changes were most apparent in females. Furthermore, subjective reporting indicates that grounding the human body to earth during sleep improves sleep and reduces pain and stress.

TRAFFIC-RELATED AIR POLLUTION AND THE DEVELOPMENT OF ASTHMA, ALLERGY AND RESPIRATORY INFECTIONS: EXTENDED FOLLOW-UP OF A BIRTH COHORT

ISEE-134 Introduction: We have previously examined the relationship between traffic-related air pollution and the development of asthmatic/allergic symptoms and respiratory infections in the first two years of life for a birth cohort (N∼ 4,000) study in The Netherlands. Here we present findings from analysis at age four. Methods: A validated model based on measurements and geographic modeling was used to assign outdoor concentrations of traffic-related air pollutants (NO2, PM2.5 and “soot”) at the home addresses of the cohort. Questionnaire-derived data on wheeze, dry nighttime cough, ear/nose/throat infections, skin rash and physician diagnoses of asthma, bronchitis, influenza and eczema at age four were analyzed in relation to air pollutants. Multiple logistic regression models controlled for gender, maternal age, parental education, parental allergy, maternal smoking, ETS exposure, other siblings, ethnicity, breastfeeding, mattress cover, and the presence of mold, pets and unvented gas appliances at home. Total IgE and specific IgE to Der p1 (house dust mite), Der f1 (house dust mite), Fel d1 (cat), Can f1 (dog), grass pollen, birch pollen, egg, milk and Alternaria was measured in a subset (n∼ 700) of the cohort. Results: Adjusted odds ratios for wheeze (e.g., OR=1.8, 95% CI = 1.1–2.7 for “soot”), doctor-diagnosed asthma (2.2, 1.1–4.7), ear/nose/throat infections (1.7, 1.1–2.5) and flu/serious colds (1.8, 1.1–3.0) indicated positive associations with air pollutants. No consistent positive associations were observed for eczema, skin rash, cough or bronchitis. In the subset of the cohort with objective measurements of allergic sensitization (specific IgE), we also observed positive associations between air pollution and sensitization to food allergens (e.g., 5.6, 1.0–15.8 for “soot”), but no indications of associations with sensitization to indoor or outdoor aeroallergens or with elevated total IgE. As sensitization to food allergens (28%) was more prevalent than sensitization to indoor (17%) or outdoor (9%) allergens, further follow-up is necessary to determine if this sensitization shifts towards aeroallergens at later ages. Conclusion: These findings at age four confirm earlier observations made at age 2 in the same cohort and indicate associations between exposure to traffic-related air pollution and asthma, allergy and respiratory infections in a birth cohort.

Wedding Day

Wedding Day Beyond the window, where light slipped in and made the lace patterns glow with late evening rose, lay fields and farther still a split rail fence and then mountains where his property ended. They sat on his feather bed and heard voices in the kitchen— laughter of women who scraped cast iron skillets and stoked the wood stove's belly, their wedding supper being stirred and baked; and talk of men, more hushed, their tobacco smoke curling through the house. To this room they had stolen and sat where tonight they would lie, his glance both bold and shy telling her what the setting sun would bring, when the noises in the kitchen and the light faded away. —Julia Nunnally Duncan 93 ...

Concentrations of domestic mite and pet allergens and endotoxin in Palestine.

A few studies have compared indoor allergens and endotoxin levels between urban and rural settings as important determinants for asthma and atopy in children. However, no study was done in the Middle East or investigated refugee camps. As part of a nested case-control study in Ramallah in 2001, we measured house dust mite and pet allergens, as well as endotoxin in dust collected from 110 children's mattresses and living room floors. Geometric mean (GM) concentrations of Dermatophagoides pteronyssinus (Der p1) antigen were 4.48 microg/g in mattress dust and 1.23 microg/g floor dust. The highest Der p1 levels were seen in refugee camps. Concentrations of Dermatophagoides farinae antigen (Der f1) were much lower (<0.08 microg/g dust). Concentrations of cat allergen (Fel d1) were highest in villages, and those of dog allergen (Can f1) were highest in mattresses from cities and in floor dust from refugee camps. GM of endotoxin levels were 25.7 EU/mg in mattress dust and 49 EU/mg dust in floor dust. Concentrations of Der p1 were high compared to Western European countries, but were lower compared to UK and Australia. Levels of pet allergens were lower than in Western Europe. Endotoxin levels were higher compared to developed countries. Indoor environmental factors such as dampness seemed to be important determinants for allergen and endotoxin, but living habits such as lack of mattress cover appeared unimportant.

Exposure to Indoor Allergens in Homes of Patients with Asthma and/or Rhinitis in Southeast Brazil: Effect of Mattress and Pillow Covers on Mite Allergen Levels

Background: Exposure and sensitization to indoor allergens have been associated with the development of asthma and other allergic diseases in many parts of the world. It is important to establish the degree of exposure, and to evaluate whether allergen control measures are effective in a particular area. Methods: Concentrations of major allergens of mites, cockroach, cat and dog were measured in dust samples from homes of 24 mite-allergic patients living in Ribeirão Preto, Brazil. Allergen concentrations were quantitated by monoclonal antibody-based ELISA. Mite-impermeable mattress and pillow covers were applied to beds in the homes of 19 of the 24 patients, and group 1 mite allergen levels were measured 1 and 6 months following intervention. Results: Patients were exposed to high concentrations of mite allergens in their homes. 87.5% of the homes presented concentrations of group 1 allergens >10 µg/g of dust in at least one site. Cockroach allergen concentrations were low in most samples. Dog allergen concentrations were significantly higher in homes with dogs as compared to those without dogs. Mean concentrations of cat allergen were 0.1 µg/g. Mite allergen concentrations in bedding samples dropped from 24 µg/g at baseline to 0.9 and 1.0 µg/g, respectively, 1 and 6 months following encasement of mattresses and pillows. Conclusions: Significant mite allergen reduction can be achieved in an area of high degree of exposure to mite allergens. Further studies evaluating the effect of this reduction on symptoms and airway inflammation will be necessary to establish the effectiveness of mite avoidance measures in our area.

Development of Sensate and Robotic Bed Technologies for Vital Signs Monitoring and Sleep Quality Improvement

More than 50 million people in the U.S. suffer from chronic sleep disorders, including snoring, bruxism, restless legs syndrome, and obstructive sleep apnea. Clinical diagnosis of severe cases often requires expensive, hospital-based polysomnography testing, while less severe cases may benefit from lower-cost in-home sensor systems to collect physiological data over multiple nights. Remedies for sleep disorders, depending on the diagnosis, range from life style modification and medication prescription to throat surgery. There is a need for unobtrusive, in-bed sensing systems as well as robotic devices to alleviate certain sleep disorder symptoms. Two companion devices are presented. The SleepSmart device is a multi-sensor mattress pad controlled by software to detect heart rate, breathing rate, body orientation and index of restlessness. A spectral analysis module is combined with an event detection module to accumulate nightly reports, signal alarms when appropriate and, in future iterations, modify ambient conditions in the bedroom. A companion project has developed Morpheus, a mattress actuation system to encourage a person to roll over in bed to alleviate snoring based on acoustic sensor data analysis. The combination of the two systems is expected to lead to novel, in-home consumer devices to aid persons affected by mild forms of sleep disorders.

Endometrial cancer incidence in relation to electric blanket use.

Endometrial cancer is associated with endogenous and exogenous estrogen excess. Some investigators have posited that electromagnetic fields may influence cancer risk through estrogenic hormonal mechanisms; however, there have been no studies reporting on electric blanket exposure in relation to endometrial cancer. The authors examined this possible association between endometrial cancer risk and electric blanket or mattress cover use as part of a population-based, case-control study. This analysis included incident endometrial cancer cases 40-79 years of age, interviewed during 1994 (n = 148; response rate, 87%) and identified from the Wisconsin tumor registry. Female controls of similar age were randomly selected from population lists (n = 659; response rate, 85%). Information regarding electric blanket and mattress cover use and endometrial cancer risk factors was obtained through structured telephone interviews approximately 1 year after diagnosis. After adjustment for age, body mass index, and postmenopausal hormone use, the risk of endometrial cancer was similar among ever users (odds ratio = 1.04, 95% confidence interval: 0.70, 1.55) and among current users (odds ratio = 0.87, 95% confidence interval: 0.49, 1.54) as compared with never users. Despite its small size and potential misclassification of exposure, this study provides evidence against an association between electric blanket or mattress cover use and endometrial cancer.

The use of a feather quilt, childhood asthma and allergic rhinitis: a prospective cohort study.

Feather bedding has long been considered as a potential source of allergen exposure and thus a potential risk factor for allergic diseases. However, recent cross-sectional studies have reported a higher risk of allergic diseases among users of synthetic bedding compared with feather-bedding users. To explore associations between early life exposure to feather bedding and the risk of developing asthma allergic rhinitis in childhood. We assessed the association between early life exposure to feather quilts and the risk of bronchial obstruction during the first 2 years of life and asthma and allergic rhinitis in a prospective 4-year cohort study of 2531 Norwegian children. At the age of 6 months, 24% of the children had a quilt with feathers, decreasing to 20% at the age of 2 years. The adjusted odds ratio for bronchial obstruction 0 to 2 years by exposure to a feather quilt at the age of 6 months was 0.59, 95% confidence interval 0.41 to 0.86, for asthma at the age of 4 years 0.38, 0.23 to 0.64 and for allergic rhinitis at the age of 4 years 0.73, 0.43 to 1.18. The use of a feather quilt in early life does not seem to increase the risk of asthma and allergic rhinitis later in childhood.

Feather bedding and house dust mite sensitization and airway disease in childhood

Feather bedding has been inversely associated with child wheeze and also with house dust mite (HDM) allergen levels. We conducted a cross-sectional analysis of the childhood component of a birth cohort study. Our aim was to examine the relation between feather bedding and HDM sensitization and airway disease. A total of 498 children (84% of eligible) residing in Northern Tasmania in 1997 who were eligible for the Tasmanian Infant Health Survey at birth in 1988 or 1989 participated. Outcome measures included atopic sensitization to Dermatophagoides farinae or Dermatophagoides pteronyssinus allergens, spirometric lung function, and child respiratory symptoms using questions from the ISAAC study. HDM sensitization was strongly associated with frequent wheeze (more than 12 episodes of wheeze compared with no wheeze in the past year) (rate ratio [RR], 19.61; confidence interval [CI], 6.94–55.56) but only weakly associated with asthma ever (RR, 1.65; CI, 1.30–2.09). Feather quilt use was associated with reduced HDM sensitization (adjusted RR [ARR], 0.60; CI, 0.45–0.80) and also reduced frequent wheeze episodes over the past year (ARR, 0.24; CI, 0.07–0.86). The reduction in wheeze was more evident among HDM-sensitized children. These findings are consistent with the possible mechanisms for feather bedding of a reduction in initial HDM sensitization and an improvement in respiratory symptoms among HDM-sensitized children. However, prospective studies are required to fully exclude selection bias.

Improtec R Barrier: a mattress cover which does not break down.

Mattress cover material breakdown in the clinical setting has been a recognized problem for over 10 years. Shortly following disruption to the surface integrity, mattresses become contaminated with body fluids, which leads to bottoming-out of the foam, putting patients at increased risk of infection and pressure ulcer formation. Collaboration between manufacturers and clinicians has produced a product that should stand up to the rigours of the healthcare market, providing safety for patients and value for money as a result of extended mattress life.
