  Background: Disinfection and sanitation are important in areas where food is involved. Thorough cleaning is a necessity to prevent growth of harmful pathogens that could affect human health. Sponges used for cleaning can serve as a vehicle for cross-contamination on food preparation surfaces. There are various methods that could be used to disinfect contaminated sponges. The usage of a microwave is one suggested method. Objective: The purpose of this study was to determine if the Scotch-BriteTM Brand, cellulose sponges contaminated with E.coli (105 cfu/ml) could be disinfected using a microwave set at three timings (30 seconds, 1 minute, and 2 minutes). Methods: The Hygiena MicroSnap was used to detect the presence (or absence) of E.coli in sponges after microwave heating. The relative light units (RLU) indicated in the monitor determined whether there were any remaining coliforms in the sample after microwaving. Results: Statistical analysis was conducted using Microsoft Excel and NCSS. After heating sponges for 30 seconds, 100% of the samples detected no E.coli. After heating for 1 minute, 70% of the samples had no E.coli present. After heating for 2 minutes, 100% of the samples detected no E.coli. The p-value of 0.03567 concludes that the results were statistically significant at the 5% significance level. Discussion: The results of this study indicate that sponges contaminated with E.coli can be disinfected using microwave heating. EHOs, food establishment operators, and the general public can use this knowledge to re-use their old sponges and avoid further cross-contamination. Conclusions: The results indicate that microwave time is associated with the presence or absence of E.coli in a sponge. However, E.coli was present in 3 samples microwaved at 1 minute. This suggests further studies are required to confirm the findings of this study. In addition, further studies are required to determine what specific time is sufficient to completely eliminate the E.coli in a contaminated sponge.

Childbirthis a processLabor of opening and depleting the cervix and the fetus down into the birth canal. Birth is a process in which the fetus and amniotic are pushed out through the birth canal. (Sarwono, 2008). According to the World Health Organization (WHO) estimates more than 585,000 mothers annually die during pregnancy or childbirth. Indonesia Health Demographic Survey (SDKI) Survey in 2012, Maternal Mortality Rate in Indonesia is still high at 359 per 100,000 live births. The purpose of this study is the knowledge of maternal knowledge, maternal age, and maternal parity associated with normal birth events at Palembang Bari Hospital 2017. This study used analytical survey method with cross sectional approach. The population in this study were all maternal mothers at the Palembang Bari Hospital in 2017. Sampling in the study was conducted non-randomly with the technique of "Accidental Sampling". Data analysis was done univariat and bivariate with Chi-Square statistical test with significance level α = 0,05. The result of this research shows that there is correlation between mother's knowledge with normal delivery incidence with p value 0,001, there is correlation between mother age with normal delivery incidence with p value 0,009, there is relation between mother parity with normal delivery incidence with p value 0,001. From result of this research hopes healthcare workers can improve normal delivery care services and more often to carry out maternal safety counseling.

Introduction: Congenital Heart Disease (CHD) is a problem with structure and function of the heart that is present at birth.  Children with CHD require special care, treatment and follow up for a number of common conditions which may be quite straining to the care givers. The objective of the study was to find out the burden of care among mothers having children with CHD. Methods: This descriptive cross-sectional study was carried out in a cardiac centre of Nepal. A total of 95 mothers having children with CHD attending outpatient department of our institute were selected as the sample for the study using non-probability purposive sampling technique. A semi structured interview questionnaire consisting of the Modified Caregiver Strain Index was used to assess the burden of care among mothers having children with CHD. Frequency and percent were used to describe the variables and chi- square test at 0.05 significance level was used to analyse associations. Results: Most (77.9%) of the mothers were regularly strained to find that their children’s health condition was deteriorating due to CHD. Nearly half (44.2%) of the mothers always had financial constrain while giving care to the child, nearly half (40%) of the mothers had done emotional adjustments to take care of their children with CHD, another two-fifths (28.4%) of the mothers sometimes had disturbed sleep and almost half (46.3%) of the mothers were always upset due to some behaviour of their child with CHD. Half (50.5%) of the mothers had high level of burden of care. Statistically significant association were found between age of the mother and level of burden of care (p value = 0.05). Similarly, the type of family (p value = 0.005), age of the children (p value = 0.000) and type of CHD (p value = 0.002) were significantly associated with the level of burden of care among the mothers. Conclusion: The study concluded that mothers tend to feel less burden of care as the child grows older, mothers having children with cyanotic heart disease tend to experience more burden of care. Mothers of less than thirty years of age and living in a joint family also experience more burden of care.

Export System

The banana agro-export sector in Ecuador provides millions of dollars in income for this concept, but with this development, a series of quality standards have been established that must be met to enter the export system. This has contributed to establishing good post-harvest production and management practices that guarantee the optimal production of bananas and plantains. The objective of this study was to determine the factors involved in the rejection of bananas (Musa acuminata) destined for international commercialization. The methodology considered the design modality of non-experimental transactional research, with a quantitative approach. The methodological design was developed in three phases at Finca 6 Hermanas located in the Barraganete sector of the San Juan parish in the Puebloviejo canton of the Los Ríos Province, Ecuador. The results highlight that the main causes for which banana rejection is generated are due to abiotic factors (damage, dry latex, scar, insect damage, broken neck, overgrowth) in a higher percentage of 79.55 % and biotic factors ( twins, diseases, short finger) by 20.45 %. The average rejection was 6 361 fingers and1 269 Kilograms (K) over the 6-week study duration. The analysis of variance turned out to be significant for variable 1 (biotic and abiotic). Ho is rejected; with the criterion of p-value < 0.0001 and F (9; 45) = 2.10., F = 13.17> F critic. In the case of variable (2) “work weeks”, Ho is accepted with the criteria obtained of p-value of 0.7694 and F (5; 45) = 2.4., As F = 0.51 < F critic, it is concludes, that with a significance level of 5% the null hypothesis is accepted. It is concluded that these figures lead to the elaboration of strategies that systemically mitigate the damages, by correcting each one of the causes that cause the deterioration of the banana and increasing the economic gains of the commercialization process.

Cefotaxime (CTX)-resistant Enterobacteriaceae are still an ongoing challenge in human and veterinary health. High prevalence of these resistant bacteria is detected in broiler chickens and the prevention of their dissemination along the production pyramid is of major concern. The impact of certain on-farm interventions on the external bacterial contamination of broiler chickens, as well as their influence on single processing steps and (cross-) contamination, have not yet been evaluated. Therefore, we investigated breast skin swab samples of broiler chickens before and during slaughter at an experimental slaughter facility. Broiler chickens were previously challenged with CTX-resistant Escherichia coli strains in a seeder-bird model and subjected to none (control group (CG)) or four different on-farm interventions: drinking water supplementation based on organic acids (DW), slow growing breed Rowan × Ranger (RR), reduced stocking density (25 kg/sqm) and competitive exclusion with Enterobacteriales strain IHIT36098(CE). Chickens of RR, 25 kg/sqm, and CE showed significant reductions of the external contamination compared to CG. The evaluation of a visual scoring system indicated that wet and dirty broiler chickens are more likely a vehicle for the dissemination of CTX-resistant and total Enterobacteriaceae into the slaughterhouses and contribute to higher rates of (cross-) contamination during processing.

An unaddressed and important issue is the role age plays in modulating response to short acting β2-agonists in individuals with asthma. The objective of this study was to identify whether age modifies genetic associations of single nucleotide polymorphisms (SNPs) with bronchodilator response (BDR) to β2-agonists. Using three cohorts with a total of 892 subjects, we ran a genome wide interaction study (GWIS) for each cohort to examine SNP by age interactions with BDR. A fixed effect meta-analysis was used to combine the results. In order to determine if previously identified BDR SNPs had an age interaction, we also examined 16 polymorphisms in candidate genes from two published genome wide association studies (GWAS) of BDR. There were no significant SNP by age interactions on BDR using the genome wide significance level of 5 × 10−8. Using a suggestive significance level of 5 × 10−6, three interactions, including one for a SNP within PRAG1 (rs4840337), were significant and replicated at the significance level of 0.05. Considering candidate genes from two previous GWAS of BDR, three SNPs (rs10476900 (near ADRB2) [p-value = 0.009], rs10827492 (CREM) [p-value = 0.02], and rs72646209 (NCOA3) [p-value = 0.02]) had a marginally significant interaction with age on BDR (p < 0.05). Our results suggest age may be an important modifier of genetic associations for BDR in asthma.

Abstract The aim of this study was to evaluate the possible difference in seminal characteristics of Dorper rams of either high, medium or low social ranks in northern Mexico (26º N). The male’s social status was quantified through a competitive behavioral test in a herd of 36 adult males, the aggressive interactions and their consequences were registered to calculate the success index (SI), where low hierarchy (LH) rams had a SI of 0 to 0.33, medium hierarchy (MH) rams had a SI of 0.34 to 0.66 and high hierarchy (HH) had a SI of 0.67 to 1. Afterwards, the rams were subjected to an estrogenized female (2 mg of estradiol cypionate) for teasing in order to collect a semen sample with an artificial vagina. The semen was evaluated for volume, motility and concentration. The seminal characteristics differences were analyzed using a one-way ANOVA tests and stablishing a p-value of 0.10 as significance level in the SPSS statistical package. Results are shown in table 1. In conclusion, low hierarchy Dorper rams show a statistical tendency to have a lower sperm concentration.

Background: A human body keeps changing physiologically, biologically, and psychologically from birth to death. There is always a change in all human faculties. But adolescence is a phase earmarked where a human body experiences drastic changes among all these faculties. And any such bodily change carrying baggage of shame, insecurity, stigma, and concealment demands on-time awareness and intervention. Aim: The aim of the study is to understand the knowledge and level of awareness regarding sexual and reproductive health among the school-going adolescents of Kashmir Valley where majority of the population belongs to Muslim conservative culture. Methodology: Due to COVID-19 lockdown, the inability of access to schools and children gave the researcher the opportunity to utilize the alternate places and a total of 550 students from classes 8, 9, and 10 were selected for the purpose. The permission was sought from the respective teachers and then the parents. The sample was a combination of boys and girls, students from both private and government-run schools. The researcher collected the data and it was tabulated systematically and analyzed using Microsoft Excel. P value was evaluated by using an application “P Value: A Statistical Tool” from Play Store. Results and Conclusion: The results depicted that higher the level of class, more the knowledge they had about the matter. Girls had a little knowledge about sexual and reproductive health than boys. This study felt a dire need of educating both parents and adolescent boys and girls regarding sexual health. The shame does not lie in educating the children but in the mishaps that may result due to unawareness about the same.
