Innovative and Sustainable Application of PET Bottle a Green Construction Overview

Objectives: In this study an effort has been made to review the research works done on plastic pet bottles as a construction material replacing traditional bricks. Methods/Statistical Analysis: Construction activities impact a lot on the environment throughout the life cycle of the project. It is seen that a pet bottle fully filled and compacted with sand achieves a much higher compressive strength than that of a brick. On the other hand as the pet bottles can easily be collected from the waste, the cost of construction of this material is comparatively very less to that of the bricks. Findings: In this study several parameters like thermal study, sound insulation, light transmission, strength parameters, and structural stability have also been reviewed. Applications: The use of PET bottle is discussed and it can be used in constructing various structures which helps in sustainable development of the society.

Predicting water filter and bottled water use in Appalachia: a community-scale case study.

A questionnaire survey was conducted in order to assess residents' perceptions of water quality for drinking and recreational purposes in a mid-sized city in northcentral West Virginia. Two logistic regression analyses were conducted in order to investigate the factors that influence bottle use and filter use. Results show that 37% of respondents primarily use bottled water and that 58% use a household filter when drinking from the tap. Respondents with lower levels of environmental concern, education levels, and lower organoleptic perceptions were most likely to perceive health risks from tap water consumption, and were most likely to use bottled water. Income, age, and organoleptic perceptions were predictors of water filter use among respondents. Clean water for recreational purposes was not found to be significant with either of these models. Our results demonstrate that bottle use and filter use are explained differently. We argue that more education and better communication about local tap water quality would decrease the use of bottled water. We demonstrate that household filters could be used as an alternative to bottled water.

High prevalence of dental caries among HIV-infected children in West Africa compared to uninfected siblings.

The objectives of this study were to investigate the association between HIV infection and dental caries among children in West Africa, and to identify factors associated with dental caries among HIV-infected children. We conducted a multi-center cross-sectional study in Mali, Senegal and Côte d'Ivoire with a random sample of HIV-infected children aged 5-15 years on antiretroviral therapy and their uninfected siblings. A standardized examination was performed by calibrated dentists. The association between the number of decayed, missing or filled permanent and primary teeth surfaces (DMFdefS) and HIV status was investigated by fitting multivariable zero-inflated negative binomial models, for each age group (<12 and ≥12 years). Factors associated with dental caries could be investigated only for HIV-infected children <12 years old. The sample included 420 HIV-infected children and 418 non-infected siblings. The median DMFdefS was 7 for the HIV-infected children and 2 for the uninfected siblings. The proportion of children with DMFdefS ≥1 was significantly higher among the HIV-infected children than uninfected children (86.0 percent versus 64.4 percent, P < 0.001). The HIV-infected children were less likely to be caries-free than the uninfected siblings in both age groups. We found a higher degree of caries experience among HIV-infected children < 12 years old, in whom it was associated with sweet drink consumption, history of night bottle use, immunosuppression, and younger age at study entry. Although preventable, the burden of dental disease was high in children from families affected by HIV in West Africa and was associated with HIV infection and immunosuppression.

Developmental Trajectories of Bottle-Feeding During Infancy and Their Association with Weight Gain.

To describe patterns of bottle-feeding across the first year postpartum and explore whether bottle-feeding trajectories are differentially associated with infant weight gain. Data came from 1291 mothers who participated in the Infant Feeding Practices Study 2. Mothers completed a prenatal questionnaire and monthly surveys of infant feeding and growth between birth and 12 months. Group-based trajectory mixture modeling was used to describe developmental trajectories of bottle-feeding intensities across the first year. Growth curve modeling was used to explore associations between bottle-feeding intensity trajectory group membership and weight-for-age z-score (WAZ) trajectories from birth to 12 months. Four qualitatively distinct trajectories of bottle-feeding were identified: (1) High-Stable: ∼100% of feeds from bottles across infancy; (2) Rapid-Increase: <30% of feeds from bottles during the neonatal assessment, increasing to ∼100% by 6 months; (3) Gradual-Increase: <10% of feeds from bottles during the neonatal assessment, gradually increasing to ∼100% by 12 months; and (4) Low-Stable: <5% of feeds from bottles across the majority of infancy. Bottle-feeding groups had significantly different WAZ trajectories across infancy; by 12 months, the High-Stable and Rapid-Increase groups had significantly higher WAZs compared with the Gradual-Increase and Low-Stable groups (p < .001). The association between bottle-feeding group membership and WAZ trajectories was not confounded by sociodemographic characteristics or the extent to which infants received breast milk. High-intensity bottle use during early infancy may place infants at higher risk for excess weight gain. Supports and policies that help mothers delay high-intensity bottle use until later infancy are warranted.

Effects of trap baits and height on stag beetle and flower chafer monitoring: ecological and conservation implications

The implementation of conservation actions requires a reliable assessment of presence and/or abundance of targeted species. This is particularly difficult for rare and elusive species. In this study the use of bottle traps and the effects of two potential baits in relation to height in the trees were tested to detect presence and assess abundance of stag beetles (Lucanidae) and flower chafers (Scarabaeidae, Cetoniinae), an important component of forest biodiversity. The study was carried out in a flood-plain forest of northern Italy. Forty-eight handcrafted traps were assigned to two height categories (1.5–2 m and 10–20 m) and three kinds of bait: (i) red wine, white wine and sugar, (ii) red wine, beer and mashed banana, (iii) no bait, as control. Fieldwork lasted 8 weeks, with 32 surveys, from May to July. Overall, we recorded 399 captures of the following species: Dorcus parallelipipedus, Lucanus cervus, Cetonia aurata, Protaetia speciosissima, P.affinis, P. morio and P. cuprea. Traps baited with red wine, white wine and sugar showed the highest detection probabilities for all the species. A clear preference for the canopy layer (traps between 10 and 20 m high) was shown by all species except for D. parallelipipedus which was mostly captured between 1.5 and 2 m of height. The study period was long enough to improve ecological knowledge on species phenology, but not enough to include the whole phenology for all of them. The method allowed the assessment of population size only for flower chafers as the number of stag beetles captures was too low.

Model Studies on Encased Fly Ash Column–Geocell Composite Systems in Soft Clay

This study narrates the use of postconsumer waste plastic water bottles for developing a new type of encasement to confine fly-ash columns fully penetrated in soft clay. Geocell-reinforced fly-ash beds along with a jute geotextile separator were also placed over the fly-ash columns, while the cellular mattresses were also made of the same type of plastic water bottles. A series of systematic model tests were carried out on encased fly-ash columns, geocell composite systems, and encased fly-ash column–geocell composite systems in soft clay, while the three different systems produced improved footing capacity of about 5-fold, 8.5 times, and 12-fold, respectively, as compared to the untreated clay bed. It was observed that with the increase in mattress height over the encased fly-ash column, the contribution from the encased column decreased accompanying the higher contribution from the geocell mattress in the overall footing capacity over the encased fly-ash column–geocell composite systems. Moreover, model tests were performed on groups of three and four end-bearing encased fly-ash columns in triangular and square patterns, respectively, to determine the efficacy of the proposed plastic bottle encasement in a group column situation. The group of four columns showed better footing capacity than that over single columns and the group of three columns.

Sleep habits and pattern in 1-14 years old children and relationship with video devices use and evening and night child activities

BackgroundSleep in childhood and adolescence is crucial for mental and physical health; however several researches reported an increasing trend towards a sleep deprivation in this age. Due to the lack of recent epidemiological studies in Italy, the aim of our study was to depict sleep habits and patterns in Italian children aged 1–14 years and to evaluate their relationships with video devices use (TV, tablet, smartphone, PC) and evening/night child activities.MethodsA structured interview was conducted during 2015 by 72 Family Pediatricians in 2030 healthy children aged 1–14 years by a cross-sectional survey named “Ci piace sognare”. Total sleep duration was calculated, 2015 National Sleep Foundation Recommendations were used as reference. Optimal sleepers were defined children sleeping in own bed all night without awakenings. Multivariable median regression was performed to identify predictors of sleep duration and multivariable logistic regression for predictors of optimal sleep.ResultsTotal sleep duration and numbers of awakenings decreased with age. Only 66.9% of children had sleep duration in agreement with Recommendations (50% in 10–14 years group). Before sleeping 63.5% of children used video devices (39.6% at 1–3 years), 39.1% read, 27.5% drank and 19.5% ate. Bottle users at bedtime were 30.8% at 1–3 years, 16.6% at 3–5 years and 4.9% at 5–7 years. Overall, 23.4% of children changed sleeping place during the night, 22.4% referred sleeping problems in the first year of life.Video devices use was negative predictor of sleep duration (-0.25 h [95%CI:-0.35,-0.14], p < 0.001). Optimal sleep was inversely related with bedroom TV (OR 0.63 [0.50,0.79], p < 0.001), with sleeping disorders in the first year (OR 0.62 [0.48,0.80], p < 0.001)), with bottle use (OR 0.64 [0.44,0.94], p < 0.05) and posivively related with high mother’s education level (OR 1.44 [1.11,1.88], p < 0.01).ConclusionsAbout one third of 1 to 14 year Italian children sleep less than recommended, one half in teenage. Modifiable risk factors for sleep abnormalities such as video devices use, bedroom TV and bottle use should be target of preventive strategies for a correct sleep. Pediatricians should give priority to the identification of sleep disorders early in life.

Factors Related to the Practice of Exclusive Breastfeeding in Different Cities of the States Minas Gerais and Bahia, Brazil

Objective: To evaluate the factors related to the time of exclusive breastfeeding (EBF) in infants from Para de Minas and Tres Coracoes (Minas Gerais) and Brumado (Bahia), Brazil. Material and Methods: All mothers attended in public and private hospitals of these cities between June and December 2012 (n=156) were invited to answer an interview related to EBF. Data were collected: (1) at maternity ward; (2) at 4 and (3) 6 months of the infant's life. In (2) and (3), data were collected by phone. Data were recorded in the SPSS software, and descriptive analyses and association of exposure and outcome variables related to the practice of EBF were performed. The chi-square test was used, considering p <0.05. Results: The total of women was in (1) 156, (2) 104 and (3) 123, and the EBF rate was 50.0%, 39.0% and 4.8%, respectively. In (1) mothers with lower schooling level have opted for EBF more frequently. In (1), the use of bottle did not interfere in EBF; on the other hand, in (2) and (3), the use of bottle has decreased the frequency of EBF (p < 0.05). Conclusion: The ideal frequency of EBF recommended by WHO to the six months of the infant's life is not followed in the evaluated cities. In addition, EBF can be influenced by the use of bottle and maternal schooling level.

The benefits of breastfeeding and associated risks of replacement with baby formulas

Breastfeeding is the nourishment designed by nature for the newborn and the infant; however its prevalence is nowadays not optimal. The aim of this article is to review the current evidence of the benefits of breastfeeding for children and society, and to elaborate the risks associated with the replacement of lactation with baby formulas. Breastfeeding is a protective factor for several infectious, atopic, and cardiovascular diseases as well as for leukaemia, necrotising enterocolitis, celiac disease, and inflammatory bowel disease. It also has a positive impact on neurodevelopment, improving IQ and reducing the risk of attention deficit disorder, and generalised developmental and behavioural disorders. Lactation can decrease the risk of sudden infant deaths syndrome by 36% and prevent 13% of infant mortality worldwide. Breastfeeding result in direct saving on the use of infant formulas and bottles, and indirectly on associated health costs, premature deaths, and quality-adjusted life years, among others. In addition, breastfeeding is environmentally friendly; it does not leave an ecological footprint in its production and consumption. The use of baby formulas and bottles have inherent risks, because they increase the risk of oral diseases, such as mouth breathing, malocclusion, alteration of bite, and tooth decay. Finally, the intestinal microbiota, oxygenation, and thermoregulation of infants are negatively affected by their use.

Mathematical Model of the Criterion of Optimization by Compensation for Designing Commercial Bottles with Lateral Surfaces of Revolution and a Straight Section along Its Silhouette

In this article, the mathematical foundations of the so called Criterion of Optimization by Compensation for designing commercial bottles with a straight section along its silhouette and with lateral surfaces of revolution is presented. Such mathematical model uses as main tools, Lagrange polynomial interpolation and Newton’s Method for Nonlinear Systems being first necessary to formulate and demonstrate a theorem. It was redesigned and manufactured a bottle of a half-liter of Fanta soda of the well-known Coca Cola Company, which uses 18.86% more material that such criterion establishes. It was expected that the redesigned bottle use 4.91% more of material with respect to what is established by the Criterion of Optimization by Compensation. However, it was reported a 13% of mistake due to important limitations that must be overcome.

Factors Associated with Early Weaning According to the Report of Mothers in a Child Friendly Hospital Initiative

Objective: To determine the prevalence and factors associated with early weaning according to the report of mothers in a Child Friendly Hospital Initiative. Material and Methods: This is an observational, cross-sectional study with a sample of 252 mother/child binomials, participants in a maternal and childcare program, in a Child Friendly Hospital Initiative in Teresina, Brazil. A semi-structured questionnaire was used as the data collection instrument, administered to the mothers in individual interviews, with questions about socioeconomic conditions, breastfeeding, period, reason and way of weaning; and non-nutritive sucking habits. Early weaning was considered when the supply of breast milk was interrupted before the six months of life. For data analysis, descriptive and bivariate analyses were performed (Pearson's Chi-Square Test and Fisher's Exact Test), with a level of significance of 5%. Results: The prevalence of early weaning was 11.9%. The reasons given for interrupting breastfeeding by the mothers were: 23,% attributions of the mother; 46.% attributions of the infant; 23.3 % organic deficiency of the mother; 6.7% influence of others; and 4.8% of the mothers were still breastfeeding. The finger and/or pacifier sucking habits (p=0.002), and the use of a bottle (p=0.003) were associated with early weaning. A significant association between the total weaning period and the socioeconomic variables was not observed (p>0.05). Conclusion: The prevalence of early weaning was low. The main factors were related to “infant attributions”, associated to children with non-nutritive sucking habits, bottle use, first tooth erupted with less than 6 months and whose mothers had formal employment.

Assessment of anaerobic blood cultures in pediatric oncology patients

IntroductionThe routine use of a single aerobic bottle for blood culture in pediatric patients has become commonplace, as anaerobic bacteria are not frequently involved in clinically significant infections. The aim of this study was to assess the usefulness of routinely performing anaerobic blood cultures in pediatric oncology patients. MethodsProspective study was conducted on pediatric (<18 years) patients affected with febrile syndrome after receiving chemotherapy for hematological or solid malignancies. Samples were inoculated into pediatric aerobic and standard anaerobic bottles (BacT/Alert automatic system). Strains were considered clinically significant, or deemed as contaminants, depending on isolation circumstances and clinical criteria. ResultsA total of 876 blood cultures from 228 patients were processed during the 21-month study period (January 2014 to September 2015). Baseline diagnosis included 143 solid tumors and 67/18 cases of leukemia/lymphoma. Bacterial growth was detected in 90 (10.2%) blood cultures for 95 different isolates, of which 62 (7.1%)/63 isolates were considered clinically significant. Among the latter, 38 (60.3%) microorganisms grew in both aerobic and anaerobic bottles, 18 (28.6%) only in aerobic bottles, and 7 (11.1%) only in anaerobic bottles. Gram-negative bacilli (33; 52.4%), mainly from the Enterobacteriaceae family, were the most frequently isolated microorganisms. Overall, only 3 out of 90 isolates (3.3%) were strict anaerobes (Propionibacterium acnes), and all of them were deemed contaminants. ConclusionStrict anaerobes did not cause significant infections in febrile pediatric oncology patients, and anaerobic blood culture bottles offered no additional advantages over aerobic media. Our results suggest that routine blood cultures should be solely processed in aerobic media in this group of patients.

Performance of Hot Asphalt Mixtures Containing Plastic Bottles as Additive

This study focuses on evaluating the resistance of polymer modified asphalt mixes and the role played by asphalt in the realm of construction is undeniably important. Addition of polymers(PB) as additives to asphalt helps to improve the strength and water repellent property of the mix and as well as helps environment in various ways and at the same time, analyzing its lower maintenance activities and service life is most important. The use of inexpensive polymers, in this case, waste polymers has without any doubt proven to be the most convenient way of reducing the cost of construction and at the same time maintaining quality. The main resolve for this research was to establish the effects of the use of plastic bottles on hot asphalt and its mixtures. In order to put this into perspective, varying percentages of asphalt mixtures were calculated and subjected to laboratory tests. The two-factor variance analysis (ANOVA) was conducted to determine the significance at various confidence limits. The results indicate that the inclusion of Polyethylene Terephthalate (PET) had a particularly substantial effect on the properties of asphalt. Consequently, it can encourage the re-utilization of waste in the manufacturing industry in an ecologically friendly and cost-effective way.

Association between harmful oral habits and the structures and functions of the stomatognathic system: perception of parents/guardians.

To verify the occurrence and associate the presence and duration of harmful oral habits with the structures and functions of the stomatognathic system. This is a cross-sectional, exploratory study. Participants' participation was formalized by the signing of an Informed Consent Form. The non-probabilistic sample comprised 289 children aged one to 12 years assisted at a Family Health Strategy unit. The data were obtained through a questionnaire to identify harmful oral habits applied to the children's parents and/or guardians. The results were considered at 5% level of significance. The statistical analyses were performed using the SPSS 19.0 software and the chi-squared association test was employed to investigate the categorical variables. The breastfeeding rate found was 85%; however, only 32.4% of the children were exclusively breastfed until six months of age. The most prevalent habits and those currently maintained were use of conventional bottle (28.62%) and conventional pacifier (23.18%). Significant correlation (p=0.001) was found between keeping the mouth open and oral and oronasal breathing. The presence of habits such as using orthodontic bottle (p=0.016) and orthodontic pacifier (p=0.001) was associated with the breathing mode reported. Habit duration was associated with the perception of changes in speech (p=0.046) and with malocclusion (p=0.014). The presence and duration of harmful oral habits were associated with the perception of changes in the structures and functions of the stomatognathic system regarding occlusion, breathing, and speech, accounting for a significant portion of the demand for rehabilitation.

DOES THE REALISTIC CONTACT AND DAILY USE CONDITIONS LIMIT THE USE OF POLYCARBONATE BABY BOTTLES FOR MIGRATION AND RESIDUE LEVEL OF BISPHENOL-A

Bisphenol-A (BPA) which is a plastic monomer acting as endocrine disruptor, can cause developmental effects and change the metabolism even at low concentrations. This study was carried out to make (i) a general assessment by performing residue analysis on the polycarbonate baby bottles, (ii) determining the factors affecting the migration of BPA to the food and (iii) determining the effect of repetitive procedures on PC baby bottles in daily use. Amount of residual BPA ranged from 0.60 ±0.05 ppm to 6.23 ±0.24 ppm and BPA migration could not be detected in any of contact conditions. Estimated daily intakes of BPA via infant formula in PC baby bottle were calculated as 1.8 µg kg -1 bw day -1 for a 3 month-old infant and 1.22 µg kg -1 bw day -1 for a 6 month-old infant which was lower than but very close to the latest value of t-TDI (4 µg kg -1 bw day -1 ) determined by EFSA. Sterilization procedures changed the amount of residual BPA significantly. Although it is concluded that the use of brand-new PC baby bottles does not pose a risk to health, sterilization procedures can lead to the higher amounts of migrated BPA which can be toxically important.

Infecciones de vía aérea superior relacionada con el uso del biberón en la alimentación del lactante menor

Introducción. La lactancia materna ofrece un efecto protector contra las infecciones respiratorias, principalmente de la vía aérea superior; por tanto, es necesario determinar si su sustitución por biberón afecta la incidencia de infecciones respiratorias del tracto superior.Método. Utilizando la metodología de práctica clínica basada en evidencia (PCBE), y según las etapas fundamentales del sistema PICO, se planteó la interrogante: en el lactante menor ¿el uso del biberón para la alimentación comparado con el amamantamiento exclusivo aumenta el riesgo de infecciones en las vías aéreas superiores? Se realizó una búsqueda de artículos en la base de datos en línea PubMed, después de establecer los criterios de inclusión y exclusión y realizar un análisis crítico se seleccionó 5 documentos que dieran respuesta a la pregunta planteada.Resultado. A partir de la búsqueda en la base de datos Pub Med, se obtuvo 969 artículos publicados; tras depurar los resultados iniciales, se logró un total de 25 publicaciones vinculadas a estudios clínicos que abordan la relación entre lactancia materna exclusiva y la incidencia de infecciones respiratorias de vía aérea superior en el lactante menor. Finalmente, se consiguió cinco publicaciones que investigaron el uso del biberón y su posible asociación con infecciones respiratorias. La evaluación de estos estudios evidenció que su calidad es de nivel medio. Las publicaciones concluyen que hay una mayor incidencia de infecciones respiratorias de vía aérea superior en infantes lactantes menores, en los que la lactancia materna no es exclusiva, sino mixta o sustituida por el uso de biberón.Conclusión. Esta revisión breve de literatura muestra que existe evidencia de mediana calidad que apoya la asociación entre el uso de biberón en la alimentación y una mayor incidencia de infecciones respiratorias de vía aérea superior en el lactante menor.

Program Kitar Semula: Persepsi Masyarakat Terhadap ReDMac

The issue of solid waste management through recycling programs in Malaysia have long been discussed in the mainstream media. However, the issue is still not taken seriously since until today the recycling rate is still low about 11 percent compared to developed countries, which already exceeds 70 percent. The situation is alarming because of its implications on the health and size of landfill is increasingly limited. Therefore, this study aimed to investigate the level of customer awareness campaign supermarkets to recycle through the reward system through the use of automatic machines discharge bottle called Deposited Recycle Machine (ReDMac). Data were collected through a questionnaire and interviews. A number of respondents involved were 362 people and they were randomly selected from five different locations. The study found that 73.2% of respondents were aware of the recycling campaign held out of which 59.7% were admitted to participate in the recycling campaign, while 77.1% of respondents agreed with the reward system to encourage consumers to practice recycling. This study convinced that the best alternative is to recycle plastic bottle through the use ReDMac, as a new way to educate the society to love environmental.

Automated Reminders and Physician Notification to Promote Immunosuppression Adherence Among Kidney Transplant Recipients: A Randomized Trial

Immunosuppression nonadherence increases the risk for kidney transplant loss after transplantation. Wireless-enabled pill bottles have created the opportunity to monitor medication adherence in real time. Reminders may help patients with poor memory or organization. Provision of adherence data to providers may motivate patients to improve adherence and help providers identify adherence barriers. Randomized controlled trial. Kidney transplant recipients (n=120) at a single center. Participants were provided wireless pill bottles to store tacrolimus and record bottle openings. Participants were randomly assigned 1:1:1 to adherence monitoring with customized reminders (including alarms, texts, telephone calls, and/or e-mails), monitoring with customized reminders plus provider notification (every 2 weeks, providers received notification if adherence decreased to<90% during that period), or wireless pill bottle use alone (control). The main outcome was bottle-measured tacrolimus adherence during the last 90 days of the 180-day trial. A secondary outcome was tacrolimus whole-blood concentrations at routine clinical visits. Adherence for the primary outcome was assessed via wireless pill bottle openings. Mean participant age was 50 years; 60% were men, and 40% were black. Mean adherence was 78%, 88%, and 55% in the reminders, reminders-plus-notification, and control arms (P<0.001 for comparison of each intervention to control). Mean tacrolimus levels were not significantly different between groups. The study did not assess clinical end points. Participants and study coordinators were not blinded to intervention arm. Provider notification and customized reminders appear promising in helping patients achieve better medication adherence, but these strategies require evaluation in trials powered to detect differences in clinical outcomes.
