HAND care & hygiene , *COVID-19 pandemic , *COMMUNICABLE diseases , *HAND washing , *DATA extraction - Abstract
Background: The human hand has constant contact with the environment, hence requires regular hand hygiene. Hand hygiene has gained recognition because of the COVID-19 pandemic and is a largely effective, affordable preventive measure against infectious diseases. This study used both national and sub-national analyses to evaluate the effect of COVID-19 handwashing guidelines on instances of diarrhea in Ghana. Methods: Data on diarrhea cases spanning February 2018 and March 2022 were retrieved from the District Health Information Management System (DHIMS 2) using a data extraction guide. The data were summarized using descriptive statistics. The difference in diarrhea cases between the pre-COVID-19 and COVID-19 periods was measured using a two-sample t-test across Ghana's 16 administrative areas. Causal Impact package in R statistical software was employed to determine the impact of the introduction of COVID-19 hand hygiene protocols on diarrheal disease. Results: A total of 5,645,533 diarrheal cases reported between February 2018 and March 2022 through the routine MIS (DHIMS2) were examined. Fifty-three percent of the cases occurred before the introduction of the hand hygiene protocol. Descriptive statistics indicated a statistically significant decrease in average diarrheal cases during the hand hygiene implementation era (13,463 cases reduction, p<0.001). Sub-national analyses revealed significant reductions in various regions: Greater Accra, Ashanti, Ahafo, Central, Eastern, Northern, Upper East, Upper West, and Volta (p<0.05). Causal impact analysis confirmed 11.0% nationwide reduction in diarrheal cases attributed to the COVID-19 hand hygiene protocols (p<0.001). Conclusion: This study underscores the effectiveness of COVID-19 hand hygiene protocols in reducing diarrheal morbidity in Ghana, with varying regional impacts. These findings advocate for the sustenance of investments and commitments made at the COVID hand hygiene protocols, particularly in this era where the pandemic appears controlled.

MENTAL illness , *PSYCHOLOGICAL distress , *MENTAL depression , *CROSS-sectional method , *MENTAL health , *COMPULSIVE eating - Abstract
Background: Research suggests that rates of mental illness are similar in rural and urban Australia, although there are significant workforce shortages in rural regions along with higher rates of chronic disease and obesity and lower levels of socioeconomic status. However, there are variations across rural Australia and limited local data on mental health prevalence, risk, service use and protective factors. This study describes the prevalence of self-reported mental health problems of psychological distress and depression, in a rural region in Australia and aims to identify the factors associated with these problems. Methods: The Crossroads II study was a large-scale cross-sectional study undertaken in the Goulburn Valley region of Victoria, Australia in 2016–18. Data were collected from randomly selected households across four rural and regional towns and then screening clinics from individuals from these households. The main outcome measures were self-reported mental health problems of psychological distress assessed by the Kessler 10 and depression assessed by Patient Health Questionnaire-9. Unadjusted odd ratios and 95% confidence intervals of factors associated with the two mental health problems were calculated using simple logistic regression with multiple logistic regression using hierarchical modelling to adjust for the potential confounders. Results: Of the 741 adult participants (55.6% females), 67.4% were aged ≥ 55 years. Based on the questionnaires, 16.2% and 13.6% had threshold-level psychological distress and depression, respectively. Of those with threshold-level K-10 scores, 19.0% and 10.5% had seen a psychologist or a psychiatrist respectively while 24.2% and 9.5% of those experiencing depression had seen a psychologist or a psychiatrist, respectively in the past year. Factors such as being unmarried, current smoker, obesity, were significantly associated with a higher prevalence of mental health problems whereas physical activity, and community participation reduced the risk of mental health problems. Compared to rural towns, the regional town had higher risk of depression which was non-significant after adjusting for community participation and health conditions. Conclusions: The high prevalence of psychological distress and depression in this rural population was consistent with other rural studies. Personal and lifestyle factors were more relevant to mental health problems than degree of rurality in Victoria. Targeted lifestyle interventions could assist in reducing mental illness risk and preventing further distress. [ABSTRACT FROM AUTHOR]

Purpose: Derangements of liver transcriptional factors and enzymes have important implications in diabetes-induced related complications. Hence, this study which consists of two experimental phases was aimed at evaluating the possible underlying molecular mechanisms of intermittent fasting (IF), exercise starvation and honey in streptozotocin (STZ)-mediated liver damage in diabetic rats. Methods: The diabetic rats were treated orally with distilled water (0.5 ml/kg), IF, starvation and honey at 1 g/kg body weight in the non-diabetic phase for four (4) weeks. After STZ injections, four (4) weeks of IF, exercise, starvation, and honey therapy were used as interventions prior to a biochemical evaluation of the liver. Results: IF and exercise greatly decreased liver transcription factor (resistin, SREBP-1c), inflammatory cytokines/enzyme (TNF-α, IL-6, IL-1ß, MPO) as well as oxidative and nitrergic stress with correspondence increased liver PPAR-γ, IL-10, SOD, CAT and GSH in diabetic rats unlike starvation and honey regimen relative to diabetic controls. Furthermore, IF and exercise significantly improved hepatic glycogen synthase and decreased glycogen phosphorylase in diabetic rats compared to the diabetic control group, but starvation and honey therapy had no such influence. IF and exercise strategically reduces STZ-induced liver metabolic disorder via through modulation of liver transcriptional factors and inhibition of pro-inflammatory cytokines, oxido-nitrergic and adipokine signaling pathway.

Concurrent wasting and stunting (WaSt) is a condition where both wasting and stunting exist in a child at the same time. This study aimed to assess the prevalence of WaSt and to identify potential associated factors in Ethiopia. A total of 33,650 children aged between 0 and 59 months were included in the analysis from the four waves of the Ethiopian Demographic and Health Survey. A mixed-effects logistic regression model was used to identify the determinants of WaSt. The prevalence of WaSt was found to be 4.7% (95% confidence interval [CI]: (4.5-4.9)), with respectively 2.5% (95% CI: 2.1-3.1) and 4.9% (95% CI: 4.7-5.2) among children in urban and rural settings. Children: (i) in the age group 12-23 months (adjusted odds ratio [AOR]: 4.16, 95% CI: (3.20-5.42)) and 24-59 months (AOR: 3.08, 95% CI: (2.28-4.17)); (ii) who were perceived by their mothers to be smaller than normal at birth (AOR: 1.98, 95% CI: (1.57-2.50)); (iii) had diarrhoea (AOR: 1.38, 95% CI: (1.11-1.71)); and (iv) fever in the past 2 weeks (AOR: 1.38, 95% CI: (1.10-1.71)) reported higher odds of WaSt. Being a female child (AOR: 0.57, 95% CI: (0.48-0.69)), having received measles vaccination (AOR: 0.71, 95% CI: (0.55-0.89)), having a mother with a normal body mass index (18.5-24.9 kg/m²) (AOR: 0.57, 95% CI: (0.48-0.68)), having a wealthier household (AOR: 0.67, 95% CI: (0.50-0.90)), and living in rural setting (AOR: 0.49, 95% CI: (0.32-0.74)) were associated with reduced odds of WaSt. The prevalence of WaSt was high, with approximately 1 in 20 Ethiopian children suffering from the condition and needing a prompt response to minimize the poor health and developmental outcomes. Children perceived by their mother to be smaller than normal at birth, older children, and babies with diarrhoea and fever had higher odds of WaSt. [ABSTRACT FROM AUTHOR]

Background: There is suboptimal early initiation of breastfeeding (EIBF) with widespread prelacteal feeding in Ghana. However, studies exploring the determinants of EIBF and prelacteal feeding are limited in Ghana. The study was conducted to assess the prevalence and determinants of EIBF and prelacteal feeding in Northern Ghana. Methods: This cross-sectional study was conducted among 508 mothers with infants aged 0–24 months in the Sagnarigu Municipality of Northern Ghana. The quantitative data were collected using a structured questionnaire adapted from Ghana's demographic and health survey. Multivariate logistic regression was used to identify the independent determinants of EIBF and prelacteal feeding. Results: The prevalence of EIBF and prelacteal feeding was 72% and 21%, respectively. The independent positive determinants of EIBF were partner support to breastfeed [adjusted Odds ratio (AOR): 1.86, 95% Confidence interval (CI): 1.09–3.17] and exposure to breastfeeding information during pregnancy (AOR = 1.63 (95% CI: 1.01–2.64). Lower odds of EIBF were observed among mothers from extended family (AOR = 0.62, 95% CI: 0.41–0.95). Regarding prelacteal feeding, negative determinants were having a normal weight baby (AOR: 0.50, 95% CI: 0.27–0.90), exposure to breastfeeding information during pregnancy (AOR: 0.54, 95% CI: 0.31–0.92), while experiencing delayed onset of lactation was a risk factor for prelacteal feeding practice (AOR: 2.35, 95% CI: 1.41–3.94). Conclusion: In this study, EIBF was slightly higher than the 2030 global target on EIBF with widespread prelacteal feeding practice. Health programs aimed at improving EIBF should focus on the women partners, nutrition counselling, and support to mothers from the extended family. In the same vein, programs aimed at discouraging prelacteal feeding practice should also target women at risk, such as those with low birthweight babies and women experiencing delayed lactation onset.

Background: Diabetes is a major public health problem affecting about 1.4 million Australians, especially in South Western Sydney, a hotspot of diabetes with higher than average rates for hospitalisations. The current understanding of the international burden of diabetes and related complications is poor and data on hospital outcomes and/or what common factors influence mortality rate in people with and without diabetes in Australia using a representative sample is lacking. This study determined in-hospital mortality rate and the factors associated among people with and without diabetes.Methods: Retrospective data for 554,421 adult inpatients was extracted from the population-based New South Wales (NSW) Admitted Patient Data over 3 financial years (from 1 July 2014-30 June 2015 to 1 July 2016-30 June 2017). The in-hospital mortality per 1000 admitted persons, standardised mortality ratios (SMR) were calculated. Binary logistic regression was performed, adjusting for potential covariates and co-morbidities for people with and without diabetes over three years.Results: Over three years, 8.7% (48,038 people) of admissions involved people with diabetes. This increased from 8.4% in 2014-15 to 8.9% in 2016-17 (p = 0.007). Across all age groups, in-hospital mortality rate was significantly greater in people with diabetes (20.6, 95% Confidence intervals CI 19.3-21.9 per 1000 persons) than those without diabetes (11.8, 95%CI 11.5-12.1) and more in men than women (23.1, 95%CI 21.2-25.0 vs 17.9, 95%CI 16.2-19.8) with diabetes. The SMR for those with and without diabetes were 3.13 (95%CI 1.78-4.48) and 1.79 (95%CI 0.77-2.82), respectively. There were similarities in the factors associated with in hospital mortality in both groups including: older age (> 54 years), male sex, marital status (divorced/widowed), length of stay in hospital (staying longer than 4 days), receiving intensive care in admission and being admitted due to primary respiratory and cardiovascular diagnoses. The odds of death in admission was increased in polymorbid patients without diabetes (28.68, 95%CI 23.49-35.02) but not in those with diabetes.Conclusions: In-patients with diabetes continue to have higher mortality rates than those without diabetes and the Australian population. Overall, similar factors influenced mortality rate in people with and without diabetes, but significantly more people with diabetes had two or more co-morbidities, suggesting that hospital mortality may be driven by those with pre-existing health/comorbidities. Urgent measures in primary care to prevent admissions among people with multiple co-morbidities are needed. [ABSTRACT FROM AUTHOR]- Published

The time-varying dynamics of the transition to renewable energy reflect the effectiveness and efficiency of energy policy. This paper investigates renewable energy transition behavior in China using Markov regime-switching models. Two distinct phases, expansion and contraction, are identified based on the growth rates of renewable energy consumption share. We find that since China started its new-energy national strategy in 2005, there has been an extended period in which it has been in the expansion state, although it occasionally reverts to a contraction state. Intriguingly, we uncover that the timing of transition state changes can be explained by the changes in policy-related, market-based instruments and risk-related indexes. These findings present implications for policymakers in developing more precise and effective policies, that drives investment choices to align with the goal of a sustainable energy system.

Background. In Ghana, anaemia is a severe public health problem among adolescent girls. In an attempt to deal with this phenomenon, Ghana Ministry of Health in collaboration with other development partners developed and launched weekly iron and folic acid supplementation program for adolescent girls in Ghanaian junior high schools. Therefore, the main aim of this study was to determine the level of compliance with iron and folic acid supplementation (IFAS) and its associated factors among adolescent girls in the Tamale Metropolis of Ghana. Methods. A cross-sectional study was conducted among 424 randomly sampled adolescent girls in the Tamale Metropolis of Ghana from April to July 2019 using an interviewer-administered structured questionnaire. Twenty school health coordinators were purposively selected to answer questions on the challenges they face in implementing the IFAS program at the school level. Bivariate logistic regression and multivariate logistic regression were used to determine associations and strength of associations, respectively, at a significant threshold of p<0.05. Results. Compliance with the IFAS was low (26.2%). Adolescent girls who were aware of anaemia (AOR = 3.57 (95% CI: 1.96, 6.51) p<0.01), had good knowledge of anaemia (AOR = 1.82 (95% CI: 1.17, 2.81) p=0.01), and had good knowledge of the IFAS program (AOR = 2.29 (95% CI: 1.47, 3.57) p<0.01) were significantly associated with compliance with the IFAS. The majority (60%) of the adolescent girls have ever missed taking the iron and folic acid (IFA) tablet because it was not issued to them by the teacher's concern while about 48.3% (169) of the adolescent girls are taking the tablet because it prevents anaemia. Adolescent girls perceiving the tablet as family planning medicine (88.8%) and unavailability of water in classrooms (18.8%) were cited as the major challenges by school health coordinators. Conclusion. Compliance with the IFAS among adolescent girls was low. Level of education and occupation of mothers of adolescent girls, awareness on anaemia, and good knowledge of anaemia and of the IFAS program were significant predictors of compliance with the IFAS. Educating the adolescent girls on anaemia and benefits of the IFAS, constant supply of the IFA tablet, and engaging parents of the adolescent girls on the program will help improve the compliance level of the adolescent girls with the IFAS.

Toxoplasmosis, caused by T. gondii, is an important zoonosis worldwide. In Ghana, information on the disease in humans abounds but scanty in animals. This study was therefore conducted to estimate the seroprevalence of T. gondii infection sheep and goats sampled from the Kumasi Abattoir in Ashanti Region, Ghana. A total of 347 serum samples collected from 170 sheep and 177 goats were analyzed for the presence of T. gondii antibodies using a commercial ELISA kit. Results of this study estimated the seroprevalence of 23.7% in goats an, 35.9% in sheep. In sheep, 24 (35.82%) out of a total of 67 male samples were positive and 37 (35.92%) out of a total of 104 female samples were positive while in goats, 6 (8.2%) bucks out of a total of 73 were positive while 36 (34.6%) does out of a total of 104 were positive. There was a significant difference in the rate of seropositivity of female goats (p-value 0.01). This study confirms the existence of T. gondii infection in small ruminants in Ghana and it showed that sheep and dogs are more at risk to T. gondii infection hence meat from such animals could be a potential risk to public health if consumed raw or undercooked.

Objective: The aim of this study was to examine the trend in socioeconomic inequalities in child undernutrition in Nigeria. Methods: The study analysed cross-sectional data from the Nigeria Demographic and Health Survey (NDHS) 2003 to 2013. The outcome variables were stunting, wasting and underweight among children under-five years. The magnitude of child undernutrition in Nigeria was estimated via a concentration index, and the socioeconomic factors contributing to child undernutrition over time were determined using the decomposition method. Results: The concentration index showed an increase in childhood wasting and underweight in Nigeria over time. The socioeconomic factors contributing to the increase in child undernutrition were: child’s age (0–23 months), maternal education (no education), household wealth index (poorest household), type of residence (rural) and geopolitical zone (North East, North West). Conclusions: To address child undernutrition, there is a need to improve maternal education and adopt effective social protection policies especially in rural communities in Nigeria.

This paper investigates a fundamental question related to the massive railway infrastructure development in China. What is the impact of high-speed rail (HSR) on regional economic disparity? The question is investigated from three perspectives. First, the influence of HSR on regional economic disparity is discussed theoretically from the perspective of New Economic Geography. Second, the variation in economic disparity at both the national and regional levels is investigated using three indexes: the weighted coefficient of variation, the Theil index and the Gini index. Third, the linkages between regional economic growth and HSR is measured empirically from a quantitative and qualitative perspective using an endogenous growth modelling framework with a panel data covering the period 2000–2014. The rail network density is adopted as a proxy to reflect the quantity change in rail investment. Three accessibility indicators (weighted average travel time, potential accessibility and daily accessibility) are introduced to capture the improvement of HSR transport quality. Our findings confirm that regional economic disparity has been decreased since the development of HSR. HSR has promoted regional economic convergence in China. Specifically, the positive effect of rail network density on regional economic growth is found to be significant in the East and North, whereas the positive effect of accessibility change is found to be more significant in the Middle Reaches of Yangtze River, the Southwest and the South China.

Objective: The present cross-sectional study aimed to determine population-attributable risk (PAR) estimates for factors associated with inappropriate complementary feeding practices in The Gambia.Design: The study examined the first and most recent Demographic and Health Survey of The Gambia (GDHS 2013). The four complementary feeding indicators recommended by the WHO were examined against a set of individual-, household- and community-level factors, using multilevel logistic analysis. PAR estimates were obtained for each factor associated with inappropriate complementary feeding practices in the final multivariate logistic regression model.Setting: The Gambia.Subjects: Last-born children (n 2362) aged 6-23 months.Results: Inadequate meal frequency was attributed to 20 % (95 % CI 15·5 %, 24·2 %) of children belonging to the youngest age group (6-11 months) and 9 % (95 % CI 3·2 %, 12·5 %) of children whose mothers were aged less than 20 years at the time of their birth. Inadequate dietary diversity was attributed to 26 % (95 % CI 1·9 %, 37·8 %) of children who were born at home and 20 % (95 % CI 8·3, 29·5 %) of children whose mothers had no access to the radio. Inadequate introduction of solid, semi-solid or soft foods was attributed to 30 % (95 % CI 7·2 %, 38·9 %) of children from poor households.Conclusions: Findings of the study suggest the need for community-based public health nutrition interventions to improve the nutritional status of Gambian children, which should focus on sociocultural and economic factors that negatively impact on complementary feeding practices early in infancy (6-11 months).

Background: Sub-Saharan Africa has one of the highest levels of child malnutrition globally. Therefore, a critical look at the distribution of malnutrition within its sub-regions is required to identify the worst affected areas. This study provides a meta-analysis of the prevalence of malnutrition indicators (stunting, wasting and underweight) within four sub-regions of sub-Saharan Africa. Methods: Cross-sectional data from the most recent Demographic and Health Surveys (2006–2016) of 32 countries in sub-Saharan Africa were used. The countries were grouped into four sub-regions (East Africa, West Africa, Southern Africa and Central Africa), and a meta-analysis was conducted to estimate the prevalence of each malnutrition indicator within each of the sub-regions. Significant heterogeneity was detected among the various surveys (I2 >50%), hence a random effect model was used, and sensitivity analysis was performed, to examine the effects of outliers. Stunting was defined as HAZ<-2; wasting as WHZ<-2 and underweight as WAZ<-2. Results: Stunting was highest in Burundi (57.7%) and Malawi (47.1%) in East Africa; Niger (43.9%), Mali (38.3%), Sierra Leone (37.9%) and Nigeria (36.8%) in West Africa; Democratic Republic of Congo (42.7%) and Chad (39.9%) in Central Africa. Wasting was highest in Niger (18.0%), Burkina Faso (15.50%) and Mali (12.7%) in West Africa; Comoros (11.1%) and Ethiopia (8.70%) in East Africa; Namibia (6.2%) in Southern Africa; Chad (13.0%) and Sao Tome & Principle (10.5%) in Central Africa. Underweight was highest in Burundi (28.8%) and Ethiopia (25.2%) in East Africa; Niger (36.4%), Nigeria (28.7%), Burkina Faso (25.7%), Mali (25.0%) in West Africa; and Chad (28.8%) in Central Africa. Conclusion: The prevalence of malnutrition was highest within countries in East Africa and West Africa compared to the WHO Millennium development goals target for 2015. Appropriate nutrition interventions need to be prioritised in East Africa and West Africa if sub-Saharan Africa is to meet the WHO global nutrition target of improving maternal, infant and young child nutrition by 2025.

Building Energy Modeling tools help forecast the energy performance of buildings. Urban energy models (UBEMs) emerged as important instruments to analyze the energy performance of buildings aggregated at different spatial resolutions, from the building level to the district level. They heavily rely on available data on geometries and measurements to create accurately calibrated energy models. However, limited research has been conducted to understand the impact of spatial and temporal resolution on the simulation results because of the difficulty of comparing results and not having a standardized procedure to report simulation errors. We review the literature on UBEM validation compared to measured energy data and show the discrepancies in the reporting accuracy. We articulate the need for consistent reporting on model accuracy and introduce a multi-dimensional Level of Detail (LoD) specification for UBEM, including geometry, thermal zoning, and spatio-temporal resolution of the measured data used to calibrate the models. Using a university campus with 70 buildings as an extensive case study, we demonstrate the performance of Bayesian calibration from the building level to the aggregated level. Our results suggest that the accuracy of urban energy prediction with annual temporal resolution can be significantly increased if calibration is performed by using building-level data. However, whenever privacy is a concern, then the data should be provided by aggregating them based on primary use type. Additionally, using monthly data to calibrate uncertain input parameters is not improving the accuracy of the models because the obtained posterior distributions for the selected parameters are not informative for monthly data. To improve this shortcoming, we suggest seasonal calibration, which is computationally costly. [ABSTRACT FROM AUTHOR]

Objective: The literature on the impact of internal migration on under-five mortality in sub-Saharan Africa has been limited. This study examined the impact of internal migration on under-five mortality rate in 27 sub-Saharan African countries. Design: The analysis used cross-sectional data from the most recent Demographic and Health Surveys of 27 sub-Saharan African countries. Information on the number of live births and the number of under-five deaths in the five years preceding the surveys in these countries was examined. Using variables from which migration data were generated, four migration statuses were computed, and the impact of each migration status on under-five mortality was analysed by using multivariate Cox proportional hazards regression models. Results: Of the 96333 live births, 7036 deaths were reported. Adjusting for internal migration status revealed a 20% increase in under-five mortality rate among urban-rural migrant mothers [HR = 1.20; 95% confidence interval (CI): (1.06–1.35)], a 40% increase in under-five mortality rates among rural non-migrant mothers, [HR = 1.40; 95% CI: (1.29–1.53)] and a 43% increase in under-five deaths among rural-urban migrant mothers [HR = 1.43; 95% CI: (1.30–1.58)]. Whilst under-five mortality rate did not change considerably when we adjusted for country and demographic variables, there were significant decreases among rural non-migrant and rural-urban migrant mothers when health care service utilization factors were adjusted for [HR = 1.20; 95% CI: (1.07–1.33) and [HR = 1.29; 95% CI: (1.14–1.45)]. The decreased risk of under-five deaths was not significant among rural non-migrant and rural-urban migrant mothers when socio-economic factors were adjusted for. Other factors for which there were significant risks of under-five deaths included household poverty, lack of health care services Conclusion: Although under-five child mortality rate declined by 52% between 1990 and 2015 (from 179 to 86 per1000 live births) in sub-Saharan Africa, the continent still has the highest rate in the world. This finding highlights the need to consider providing education and health care services in rural areas, when implementing interventions meant to reduce under-five mortality rates among internal migrant mothers.

Objective: The double burden of malnutrition affects many low and middle-income countries. This study aimed to: a) determine temporal trends in the prevalence of underweight, stunting, and at risk of overweight/ overweight or obesity in Indonesian children aged 2.0–4.9 years; and b) examine associated risk factors. Design: A repeated cross-sectional survey. This is a secondary data analysis of waves 1, 2, 3, and 4 (1993, 1997, 2000, and 2007) of the Indonesian Family Life Survey, which includes 13 out of 27 provinces in Indonesia. Height, weight and BMI were expressed as z-scores (2006 WHO Child Growth Standards). Weight-for-age-z-score <-2 was categorised as underweight, height-for-age-z-score <-2 as stunted, and BMI-z-score >+1, >+2, >+3 as at-risk, overweight and obese, respectively. Results: There are 938, 913, 939, and 1311 separate children in the 4 waves, respectively. The prevalence of stunting decreased significantly from waves 1 to 4 (from 50.8% to 36.7%), as did the prevalence of underweight (from 34.5% to 21.4%). The prevalence of ‘at-risk’/overweight/obesity increased from 10.3% to 16.5% (all P<0.01). Stunting and underweight were related to lower birth weight, being breastfed for 6 months or more, having parents who were underweight or had short stature, and mothers who never attended formal education. Stunting was also higher in rural areas. Being at-risk, or overweight/obese were closely related to being in the youngest age group (2–2·9 years) or male, having parents who were overweight/obese or having fathers with university education. Conclusions: The double burden of malnutrition occurs in Indonesian children. Development of policy to combine the management of chronic under-nutrition and over-nutrition is required.

- Abstract
Background: In South Sudan, birth deliveries attended by unskilled birth attendants put the mothers and their newborns at increased risk of perinatal morbidity and mortality. The aim of this study was to identify factors associated with delivery by unskilled birth attendants or by unassisted delivery. Design: We examined data for 2,767 (weighted total) women aged 15-49 years who delivered at home 2 years prior to the South Sudan Household Health Survey 2010. Multinomial logistic regression analyses were used to identify factors associated with delivery by unskilled birth attendants or by unassisted delivery. Results: The prevalence of delivery by unskilled birth attendants was 19% [95% confidence interval (CI) 17.0, 20.5], by skilled birth attendants (SBAs) was 45% (95% CI 42.4, 47.0), and by unassisted delivery was 36% (95% CI 34.2, 38.6). After adjusting for potential confounders, the following factors were associated with the increased odds for unassisted delivery or delivery by an unskilled birth attendant: mothers with no schooling, who did not attend antenatal care (ANC) during pregnancy, who had lower quality of ANC services, from poor households, or who had no prior knowledge about obstetric danger signs. Conclusions: We found that non-utilization of maternal health care services, such as ANC, was significantly associated with unattended birth delivery or delivery by unskilled health providers. The increased uptake of SBAs at delivery will require easier access to ANC services, health promotion on the importance and benefits of SBAs for delivery, targeting both mothers and their families, and the training and deployment of more SBAs across the country.

Suboptimal complementary feeding practices play a crucial role in the health and development of children. The objective of this research paper was to identify factors associated with suboptimal complementary feeding practices among children aged 6-23 months in seven francophone West African countries, namely, Benin, Burkina Faso, Cote d' Ivoire, Guinea, Mali, Niger and Senegal. This study covered 22 376 children aged 6-23 months from the seven countries surveyed ( Benin: 3732 children; Burkina Faso: 4205 children; Cote d' Ivoire: 2109 children, Guinea: 1944 children, Mali: 3798 children, Niger: 3451 children and Senegal: 3137 children). The most recent Demographic and Health Survey datasets of the various countries were used as data sources. A set of individual-, household- and community-level factors were used to examine the four complementary feeding indicators. Multivariate analysis revealed that the youngest age bracket (6-11 months) of children, administrative/geographical region, mother's limited or non-access to the mass media, mothers' lack of contact with a health facility, rural residence, poor households and non-working mothers were the main factors associated with suboptimal complementary feeding in the countries surveyed. Our findings highlight the need to consider broader social, cultural and economic factors when designing child nutritional interventions. [ABSTRACT FROM AUTHOR]

Suboptimal complementary feeding practices have a detrimental impact on a child's growth, health and development in the first two years of life. They lead to child malnutrition, which contributes to the high prevalence of stunting (38%) and underweight (28%) reported for children <5 years of age in Sub- Saharan Africa. This study analysed complementary feeding practices in four anglophone West African countries ( Ghana, Liberia, Nigeria and Sierra Leone) using the most recent Demographic and Health Surveys. The study covered 12 623 children aged 6-23 months from four anglophone West African countries ( Ghana: 822 children: Liberia: 1458 children, Nigeria: 8786 children and Sierra Leone: 1557 children). Four complementary feeding indicators were examined against a set of individual-, household- and community-level factors, using multiple regression analysis. Multivariate analyses found that lack of post-natal contacts with health workers, maternal illiteracy and geographical region were common determinants of delayed introduction of solid, semi-solid or soft foods across all four countries. Predictors for minimum dietary diversity, minimum meal frequency and minimum acceptable diet included children aged 6-11 months, administrative/geographical region, poorer household income and limited access to media. The authors recommend that the four anglophone West African countries studied should prioritise efforts to improve complementary feeding practices in order to reduce child morbidity and mortality. Interventional studies on complementary feeding should target those from poor and illiterate households. [ABSTRACT FROM AUTHOR]

The objective of this paper was to review the policy implications of inadequate complementary feeding among children aged 6-23 months in West Africa. The review was undertaken from the initial results and findings from a series of studies on the comparison of complementary feeding indicators among children aged 6-23 months in four anglophone and seven francophone West African countries. It also examined a study of the determinants of suboptimal complementary feeding practices among children aged 6-23 months in those countries. Among the four complementary feeding indicators, it was only the introduction of solid, semi-solid or soft foods that was adequate among children in all the West African countries surveyed. The rates of the other complementary feeding indicators were found to be inadequate in all countries surveyed, although relatively better among children in the anglophone countries. Alarmingly, low rates of minimum acceptable diet were reported among children from both the anglophone and the francophone countries. Infants 6-11 months of age, children living in poor households, administrative/geographical regional differences and mothers' access to the media were some of the common risk factors for optimal complementary feeding practices in these countries. Assessing complementary feeding indicators and determinants of suboptimal complementary feeding practices in these West African countries is crucial to improving infant and young child feeding practices. It is recommended that governments and stakeholders of the West African countries studied make greater efforts to improve these critical practices in order to reduce child morbidity and mortality in the West Africa sub-region. Intervention studies on complementary feeding should target those socio-demographic factors that pose risks to optimal complementary feeding. [ABSTRACT FROM AUTHOR]

Stunting, a consequence of suboptimal complementary feeding practices, continues to be a significant public health problem in West Africa. This paper aimed to compare rates of complementary feeding indicators among children aged 6-23 months between four Anglophone and seven Francophone West African countries. The data used for this study were the most recent Demographic and Health Surveys of the various countries, namely Ghana, Liberia, Nigeria, Sierra Leone ( Anglophone countries), Benin, Burkina Faso, Cote d' Ivoire, Guinea, Mali, Niger and Senegal ( Francophone countries) conducted between 2006 and 2013. The analyses were limited to last-born children aged 6-23 months and covered 34 999 children: 12 623 in the Anglophone countries and 22 376 children in the Francophone countries. Complementary feeding indicators were examined using the method proposed by the World Health Organization ( WHO) in 2008. Introduction of solid, semi-solid or soft foods among children aged 6-23 months in the Anglophone countries ranged from 55.3% ( Liberia) to 72.6% ( Ghana). The corresponding rates for the Francophone countries ranged from 29.7% ( Mali) to 65.9% ( Senegal). The average rate of minimum dietary diversity for the Anglophone countries was 32.0% while that of the Francophone countries was only 10.6%. While the minimum meal frequency rates ranged between 42.0% ( Sierra Leone) and 55.3% ( Nigeria) for the Anglophone countries, the corresponding rates for the Francophone countries ranged between 25.1% ( Mali) and 52.4% ( Niger). Both the Anglophone and the Francophone countries reported alarmingly low rates of minimum acceptable diet, with the two groups of countries averaging rates of 19.9% ( Anglophone) and 5.5% ( Francophone). The rates of all four complementary feeding indicators across all the 11 countries fell short of the WHO's requirement for optimal complementary feeding practices. Intervention studies using cluster-randomised controlled trials are needed in order to improve the nutritional status of young children in West Africa. [ABSTRACT FROM AUTHOR]

CARBON emissions , *NATURAL gas production , *ENERGY consumption - Abstract
In this study, we aim to uncover the convergence pattern of carbon emissions and its determinants towards effective reduction policies. In particular, we contribute to the emissions convergence literature by examining convergence in CO 2 emissions for a sample of Association of Southeast Asian Nations (ASEAN) member states, spanning the period from 1960 to 2018. We adopt the log (t) club convergence approach and examine convergence patterns in total CO 2 emissions as well as emissions disaggregated by sources. We focus on emissions emerging from coal, oil, natural gas and cement production. The findings from the full sample analysis reveal two sub-convergent clubs that reflect population size, geography, and energy demand. The disaggregated analysis by sources show that the sources of emissions significantly influence convergence behaviour across the ASEAN countries investigated. We find that the transition paths of emissions are more pronounced for oil, gas and cement production with a large number of non-converging states. To ascertain the reason behind this result, we examine the determinants of the convergence process. We detect that urbanization plays a vital role in the convergence path of carbon emissions and calls for urgent efforts to decarbonize urbanization-related infrastructure processes. • We investigate club convergence in CO 2 emissions among ASEAN member states. • We focus on convergence in total CO 2 emissions and emissions by sources. • We use the Phillips-Sul club clustering methodology. • Finding shows sources of emissions significantly influence convergence behaviour. • Evidence of multiple clubs with pronounced transition paths for oil and cement.

This study aims to identify residential fire risk factors and their health outcomes in terms of hospital admissions from burns and smoke inhalation together with related readmissions, length of hospital stay (LOS), costs of hospitalisation and mortality within 30 days of the fire incidence. Residential fire-related hospitalisations from 2005 to 2014 in New South Wales, Australia were identified using linked data. Univariate and multivariable Poisson regression analyses were performed to determine factors associated with residential fires on hospital admission and loss of life. During the study period, 1862 individuals were hospitalised due to residential fires. In terms of prolonged LOS, high hospitalisation cost or mortality, fire incidents' that damaged both contents and structures of the property; were ignited by smokers' materials and/or due to mental or physical impairment of the residents had more adverse outcomes. Individuals aged 65 and over with comorbidities and/or acquired severe injuries from the fire incident were at a higher risk of long-term hospitalisation and death. This study provides information to response agencies in communicating fire safety messages and intervention programs to target vulnerable population. In addition, it also supplies indicators on hospital usage and LOS following residential fires to health administrators. • Residential fires damaging both contents and structures due to mental or physical impairment had more adverse outcomes. • Individuals aged 65+ with comorbidities and/or acquired severe injuries from fire incident were at a higher risk of death. • Only 27% of the residential fire-related hospitalisations had fire services attendence.

Background: In Nigeria, suboptimal breastfeeding practices are contributing to the burden of childhood diseases and mortality. This study identified the determinants of key suboptimal breastfeeding practices among children 0-23 months in Nigeria. Method: Data on 10,225 children under-24 months were obtained from the 2008 Nigeria Demographic and Health Survey (NDHS). Socio-economic, health service and individual factors associated with key breastfeeding indicators (early initiation of breastfeeding, exclusive breastfeeding, predominant breastfeeding and bottle feeding) were investigated using multiple logistic regression analyses. Results: Among infants 0-5 months of age, 14% [95% confidence Interval (CI): 13%, 15%] were exclusively breastfed and 48% [95% CI: 46, 50%] were predominantly breastfed. Among children aged 0-23 months, 38% [95% CI 36, 39%] were breastfed within the first hour of birth, and 15% [95% CI: 14, 17%] were bottle-fed. Early initiation of breastfeeding was associated with higher maternal education, frequent antenatal care (ANC) visits and birth interval but deliveries at a health facility with caesarean section was associated with delayed initiation of breastfeeding. Educated mothers, older mothers and mothers from wealthier households exclusively breastfeed their babies. The risk for bottle feeding was higher among educated mothers and fathers, and women from wealthier households including mothers who made frequent ANC visits. Conclusion: Socio-economic and health service factors were associated with suboptimal breastfeeding practices in Nigeria. To improve the current breastfeeding practices, breastfeeding initiatives should target all mothers - particularly low SES mothers - including, national and sub-national health policies that ensure improved access to maternal health services, and improvements to baby friendly hospital and community initiatives for mothers.

ObjectiveTo explore complementary feeding practices and identify potential risk factors associated with inadequate complementary feeding practices in Ghana by using the newly developed WHO infant feeding indicators and data from the nationally representative 2008 Ghana Demographic and Health Survey.DesignThe source of data for the analysis was the 2008 Ghana Demographic and Health Survey. Analysis of the factors associated with inadequate complementary feeding, using individual-, household- and community-level determinants, was done by performing multiple logistic regression modelling.SettingGhana.SubjectsChildren (n 822) aged 6–23 months.ResultsThe prevalence of the introduction of solid, semi-solid or soft foods among infants aged 6–8 months was 72·6 % (95 % CI 64·6 %, 79·3 %). The proportion of children aged 6–23 months who met the minimum meal frequency and dietary diversity for breast-fed and non-breast-fed children was 46·0 % (95 % CI 42·3 %, 49·9 %) and 51·4 % (95 % CI 47·4 %, 55·3 %) respectively and the prevalence of minimum acceptable diet for breast-fed children was 29·9 % (95 % CI 26·1 %, 34·1 %). Multivariate analysis revealed that children from the other administrative regions were less likely to meet minimum dietary diversity, meal frequency and acceptable diet than those from the Volta region. Household poverty, children whose mothers perceived their size to be smaller than average and children who were delivered at home were significantly less likely to meet the minimum dietary diversity requirement; and children whose mothers did not have any postnatal check-ups were significantly less likely to meet the requirement for minimum acceptable diet. Complementary feeding was significantly lower in infants from illiterate mothers (adjusted OR=3·55; 95 % CI 1·05, 12·02).ConclusionsThe prevalence of complementary feeding among children in Ghana is still below the WHO-recommended standard of 90 % coverage. Non-attendance of postnatal check-up by mothers, cultural beliefs and habits, household poverty, home delivery of babies and non-Christian mothers were the most important risk factors for inadequate complementary feeding practices. Therefore, nutrition educational interventions to improve complementary feeding practices should target these factors in order to achieve the fourth Millennium Development Goal.

This study investigates the ex post impact of the Beijing–Shanghai high speed rail (BJHSR) on housing values. A dataset including 1016 housing communities from the 22 cities along the BJHSR line are analyzed in the tradition of the hedonic pricing model using three estimation procedures: a robust ordinary-least square regression, a Box-Cox transformation technique and a spatial econometric model. After controlling for physical characteristics of housing property, neighboring environment and locational accessibility, the study finds that the establishment of the BJHSR service has a considerable regional impact (including local effects and spillover effects) on housing values in medium and small cities but a negligible impact in larger capital cities. This may be the results of the competitive nature of housing market in Chinese capital cities. [ABSTRACT FROM AUTHOR]

This paper expands upon the classical Granger causality test with spatial dimensions to investigate the causal linkages between regional economic output and surface transportation infrastructure with a focus on the Northeast Corridor in the United States. To improve the validity of estimation, a panel data set of surface transportation infrastructure including highways, public intercity railways, and public transit, which are measured in real monetary value for the period 1991-2009, is adopted. Granger causality tests with integrations of various forms of spatial spillover interactions are analyzed in different spatial vector autoregressive models. The empirical results reveal that the spatial Granger causality test is able to capture a broader geographic scale of causality than the classical approach, but the causality between regional economic output and surface transportation infrastructure is sensitive to the model specifications.

Data envelopment analysis is used to assess the efficiency of broadband Internet adoption and use in the U. S. Analyses at the state level from 2005 to 2007 suggest that broadband adoption and use is not equally efficient across the U. S. states. Although the instantaneous efficiencies are relatively high for many states, the changes in total factor productivity suggest that the efficiency of broadband adoption and use still increases over time. Moreover, it is observed that efficiency values are often spatially autocorrelated, which suggests spatial dependency from spillovers or interstate competition. This leads to a particular spatial diffusion pattern in broadband adoption. Although states have different strategies in support of broadband expansion they need to identify their shortcomings and use the appropriate mix of inputs (and outputs) to improve their efficiencies.

Improving infant and young child feeding practices will help South Asian countries achieve the Millennium Development Goal of reducing child mortality. This paper aims to compare key indicators of complementary feeding and their determinants in children aged 6-23 months across five South Asian countries - Bangladesh, India, Nepal, Pakistan and Sri Lanka. The latest Demographic and Health Survey and National Family Health Survey India data were used. The analyses were confined to last-born children aged 6-23 months - 1728 in Bangladesh, 15 028 in India, 1428 in Nepal, 2106 in Sri Lanka and 443 infants aged 6-8 months in Pakistan. Introduction of solid, semi-solid or soft foods, minimum dietary diversity, minimum meal frequency and minimum acceptable diet, and their significant determinants were compared across the countries. Minimum dietary diversity among children aged 6-23 months ranged from 15% in India to 71% in Sri Lanka, with Nepal (34%) and Bangladesh (42%) in between. Minimum acceptable diet among breastfed children was 9% in India, 32% in Nepal, 40% in Bangladesh and 68% in Sri Lanka. The most consistent determinants of inappropriate complementary feeding practices across all countries were the lack of maternal education and lower household wealth. Limited exposure to media, inadequate antenatal care and lack of post-natal contacts by health workers were among predictors of inappropriate feeding. Overall, complementary feeding practices among children aged 6-23 months need improvement in all South Asian countries. More intensive interventions are necessary targeting the groups with sup-optimal practices, while programmes that cover entire populations are being continued. [ABSTRACT FROM AUTHOR]

Inappropriate complementary feeding increases the risk of undernutrition, illness and mortality in infants and children. This study uses a subsample of 1428 children of 6-23 months from Nepal Demographic and Health Survey (NDHS), 2006. The 2006 NDHS was a multistage cluster sample survey. The complementary feeding indicators were estimated according to the 2008 World Health Organization recommendations. The rate of introduction of solid, semi-solid or soft foods to infants aged 6-8 months was 70%. Minimum meal frequency and minimum dietary diversity rates were 82% and 34%, respectively, and minimum acceptable diet for breastfed infants was 32%. Multivariate analysis indicated that working mothers and mothers with primary or no education were significantly less likely to give complementary foods, to meet dietary diversity, minimum meal frequency and minimum acceptable diet. Children living in poor households were significantly less likely to meet minimum dietary diversity and minimum acceptable diet. Mothers who had adequate exposure to media, i.e. who watch television and who listen to radio almost every day, were significantly more likely to meet minimum dietary diversity and meal frequency. Infants aged 6-11 months were significantly less likely to meet minimum acceptable diet [adjusted odds ratio (OR) = 3.13, confidence interval (CI) = 2.16-4.53] and to meet minimum meal frequency (adjusted OR = 4.46, CI = 2.67-7.46). In conclusion, complementary feeding rates in Nepal are inadequate except for minimum meal frequency. Planning and promotion activities to improve appropriate complementary feeding practices should focus on illiterate mothers, those living in poor households, and those not exposed to media.

The literature on regional change in post-reform China suggests a consistent pattern of increasing regional disparity during 1990s. This article explains disparity through the lens of industrial transition as reflected in the three major economic sectors, agriculture, manufacturing, and services from 1995 to 2004. Increased economic output in China has been accompanied by dramatic changes in employment structure at both the national and regional level. Changes at the provincial level have been driven by national trends and changes of industry mix as well as regional characteristics. The importance of industry mix and regional competitive advantage varies across sectors and has different impacts on employment and output. This analysis indicates that employment loss in agriculture in the western and central regions has not been made up by the increases in other sectors. The differential rate of transition in economic structure toward the secondary and tertiary sectors has contributed to the widening gap between the coastal areas and the other parts of the country. Our exploratory spatial analysis with regard to the extended shift-share components indicates significant spatial autocorrelation both at the sectoral and provincial level. The necessity of integrating spillover effects into any policy intervention is demonstrated. Then sensitivity analysis is carried out to examine how the selection of two spatial weight matrices will influence the decomposition results. [ABSTRACT FROM AUTHOR]

Background: Exclusive breast feeding (EBF) has important protective effects on the survival of infants and decreases risk for many early-life diseases. The purpose of this study was to assess the factors associated with EBF in Nigeria. Methods: Data on 658 children less than 6 months of age were obtained from the Nigeria Demographic and Health Survey (NDHS) 2003. The 2003 NDHS was a multi-stage cluster sample survey of 7864 households. EBF rates were examined against a set of individual, household and community level variables using a backward stepwise multilevel logistic regression method. Results: The average EBF rate among infants younger than 6 months of age was 16.4% (95%CI: 12.6%-21.1%) but was only 7.1% in infants in their fifth month of age. After adjusting for potential confounders, multivariate analyses revealed that the odds of EBF were higher in rich (Adjusted Odds Ratios (AOR) = 1.15, CI = 0.28-6.69) and middle level (AOR = 2.45, CI = 1.06-5.68) households than poor households. Increasing infant age was associated with significantly less EBF (AOR = 0.65, 95%CI: 0.51-0.82). Mothers who had four or more antenatal visits were significantly more likely to engage in EBF (AOR = 2.70, 95%CI = 1.04-7.01). Female infants were more likely to be exclusively breastfed than male infants (AOR = 2.13, 95%CI = 1.03-4.39). Mothers who lived in the North Central geopolitical region were significantly more likely to exclusively breastfeed their babies than those mothers who lived in other geopolitical regions. Conclusions: The EBF rate in Nigeria is low and falls well short of the expected levels needed to achieve a substantial reduction in child mortality. Antenatal care was strongly associated with an increased rate of EBF. Appropriate infant feeding practises are needed if Nigeria is to reach the child survival Millennium Development Goal of reducing infant mortality from about 100 deaths per 1000 live births to a target of 35 deaths per 1000 live births by the year 2015.

Objective: To investigate domestic sexual violations in southeastern Nigeria and the opinions of married women regarding sexual rights for women.Method: Married women attending gynecologic clinics at 3 major hospitals in Enugu, Nigeria, completed a structured questionnaire.Results: A culture of male dominance seemed to be the leading cause for the following high rates: husband's total monopoly on decisions regarding sex, 54.1%; inability to refuse the husband's demands for sex, 60.7%; sex-related verbal abuse, 39.3%; sex-related physical violence, 16.2%; and forced sex, 19.1%. Women with a university education and unemployed women reported sexual violations more frequently than did others. Most respondents supported sexual rights for women.Conclusion: Married women in southeastern Nigeria still are denied sexual rights, apparently owing to a culture of male dominance. A higher education alone may not lead to the advent of sexual rights for women, and a greater emphasis should be placed on societal reorientation. [ABSTRACT FROM AUTHOR]- Published

Abstract: A model for risk and reliability analysis of complex multifunctional production process systems is presented. The model employs Monte-Carlo and Markov Chain algorithms that uses a weighted index to train and simulate the fuzzy hazard data sets which represents failure outcomes of risk component transient and non-transient systems. Early simulation results shows that hazard rates and the risk of containment loss from typical floating production and storage offloading (FPSO)-Riser system for the risk components in parallel or series increases exponentially with time and decreases as safety ratings fraction increases. The reliability value decreases with time and safety fraction (SFAC) for all fuzzy hazard classifications. The results of the computed mean time before repair (MTBR) show that the minimum computed years before repair range from about 0.5 computed year for worst case (fuzzy class 1, very likely to fail) to almost 5 million computed years for the best case (fuzzy class 5, remote to fail) assuming availability is 80%. This new method for risk assessment would allow users of the technique generate skewed failure data hazard rates to predict actual failure outcomes of multifunctional processes and complex risk systems.

Background: In 2007 Australia experienced its first outbreak of highly infectious equine influenza. Government disease control measures were put in place to control, contain, and eradicate the disease; these measures included movement restrictions and quarantining of properties. This study was conducted to assess the psycho-social impacts of this disease, and this paper reports the prevalence of, and factors influencing, psychological distress during this outbreak. Methods: Data were collected using an online survey, with a link directed to the affected population via a number of industry groups. Psychological distress, as determined by the Kessler 10 Psychological Distress Scale, was the main outcome measure. Results: In total, 2760 people participated in this study. Extremely high levels of non-specific psychological distress were reported by respondents in this study, with 34% reporting high psychological distress (K10 > 22), compared to levels of around 12% in the Australian general population. Analysis, using backward stepwise binary logistic regression analysis, revealed that those living in high risk infection (red) zones (OR = 2.00; 95% CI: 1.57-2.55; p < 0.001) and disease buffer (amber) zones (OR = 1.83; 95% CI: 1.36-2.46; p < 0.001) were at much greater risk of high psychological distress than those living in uninfected (white zones). Although prevalence of high psychological distress was greater in infected EI zones and States, elevated levels of psychological distress were experienced in horse-owners nationally. Statistical analysis indicated that certain groups were more vulnerable to high psychological distress; specifically younger people, and those with lower levels of formal educational qualifications. Respondents whose principal source of income was from horse-related industry were more than twice as likely to have high psychological distress than those whose primary source of income was not linked to horse-related industry (OR = 2.23; 95% CI: 1.82-2.73; p < 0.001). Conclusion: Although, methodologically, this study had good internal validity, it has limited generalisability because it was not possible to identify, bound, or sample the target population accurately. However, this study is the first to collect psychological distress data from an affected population during such a disease outbreak and has potential to inform those involved in assessing the potential psychological impacts of human infectious diseases, such as pandemic influenza.

Galectins (GAL) constitute an evolutionarily conserved family of β-galactoside-binding proteins that are secreted. They are involved in the regulation of homeostasis, innate and adaptive immune responses to infectious challenge. The mushroom Coriolus versicolor (CV) has been reported to boost suppressed immune function, extending the survival rate and improving quality of life in man. The objective of this study was to evaluate the effect of mushroom probiotics on the secretion of Galectins in goat blood. Ten BoerXSpanish female goats (5 weeks of age) were used for this study. Powdered CV was soaked in cold water and sterile filtered. Following initial screening for infection, goats were assigned to two groups of five (n = 10). Goats were drenched daily with 10 mL cold (treatment I) extract for 4 weeks. A control group of five age-matched goats received sterile water (treatment II). Blood samples were collected on a weekly basis. The concentration plasma protein was determined by using Pierce BCA kit (Thermo Scientific Pierce, Rockford, IL). Galectins-1, -3, -8, -9 and -12 concentration was detected by using a commercial ELISA kits (ABclonal Biotechnology, Woburn, MA). There was an effect of treatment in total plasma protein concentration when compared to the control group (P < 0.02). Galectins tested were secreted in both control and treatment groups. Treatment with CV decreased the concentration of Gal-1, 8 and 9 and increased the concentration of Gal-3 and -12 (P < 0.05). Results from this study indicate that mushroom probiotics can modulate the secretion of GAL. [ABSTRACT FROM AUTHOR]

Abstract: Sustainable transportation institutions must promote efficient transport utilization and reflect regional demands that often do not align themselves with traditional patterns of political organization. These institutions must confront political legitimacy, economic efficiency and social representation as well as functional effectiveness. Increasing interdependence of mobility demands in terms of safety and efficiency and the embeddedness of transportation in civil society has caused issues of equity, fiscal management and environmental externalities to put new stresses on old slowly evolving transport management institutions. Key challenges to sustainability relate to effective use of technology in management of international trade and the management of spatial externalities in complex urban infrastructure investments. In both cases significant progress has been made using regional strategies, but tension continues between issues of efficiency and privatization on the one hand and equity and public good responsibilities on the other hand. Institutions evolve and change with these cross pressures and different cultural contexts. Examples of these evolutionary changes are explored in terms of the interaction between technology and governance in international trade and in the frameworks intended to manage metropolitan transportation in the US.

PIPELINES , *COMPUTER simulation , *LEAK detectors - Abstract
A new model to detect leaks optimally in liquid pipelines is presented. The model uses the concept based on the Liapunov stability criteria to evolve a criterion for pipeline leak detection. A flow model was derived for a typical pipeline flow system, and the inclusion of leak factor kL in the flow model gives an indication of the relative degree of deviation from equilibrium or no leak situation. The numerical solution by the implicit finite difference scheme was used to solve the transient second-order partial differential equations describing the flow process. A set of parametric velocity and pressure profiles were generated and validated using industry data. A stability matrix, useful for determining the eigenvalues (λ’s), evolves from the deviation model of velocity and pressure. A leak is detected whenever any of the eigenvalues is less than −1, whereas a surge in the pipeline is detected whenever any of the eigenvalues is greater than 1. The simulation profiles of eigenvalues of a crude oil transporting pipeline segment, of a pipeline network of an operating oil company in the Niger Delta region of Nigeria, show that pressure deviations are more sensitive parameter for leak detection than volume deviations. Volume deviations appear to be good indicators for larger leak systems. Single leak situation as well as double leak situations in a pipeline system were analyzed and discussed.

The article presents a response to the article of Liam Downey on environmental justice. The issue of environmental justice has been given its legitimacy by widespread concern over whether or to what extent minorities, low-income, or other disadvantaged or susceptible populations face disproportionately high exposure to environmental hazards, and as a consequence risk experiencing greater health problems. This is a difficult issue to research and understand for a number of reasons. It is highly charged politically with consideration of factors such as discrimination, racism, and injustice. It is socially complex in terms of the meanings of justice involved, for instance, with different considerations regarding procedural justice and distributional justice. It involves complex scientific considerations related to spatial variables, such as social ecology, definitions of community, and appropriate levels of spatial aggregations as well as important analytic is sues related to spatial dependence and heterogeneity.

- Abstract
The chemical composition and microbial diversity influence the safety, quality and utility of digestate. This study investigated the minimum temperature and time for conversion of digestate to a safe biofertilizer. Digestate, a byproduct of anaerobic digestion was treated at various temperatures, 28 ± 2, 55, 60, 70 and 80 °C at varying durations, 0, 20, 30, 40 and 60 minutes. The potential for rhizobacteria was examined and essentially, at 70 °C and 40 min bacterial counts were 8.05 ± 0.71 × 102 cfu/ml and less than the 1000 cfu/ml permissible limits. At this temperature and time, there were no recorded counts of Salmonella or Escherichiae. Identified species were Pseudomonas sp, Proteus spp., Enterobacter sp., Escherichia coli, Citrobacter sp., Klebsiella sp, Enterococcus sp., Streptococcus sp., Bacillus sp., Yersinia sp., Salmonella sp and Shigella sp. Physicochemical result suggests that digestate processed at 70 °C and 40 mins possess pH, total nitrogen, nitrate and total phosphorus within defined standards while heavy metal concentration was below permissible limits. The rhizobacterial screening showed that Pseudomonas sp., Proteus sp., Bacillus sp. and Streptococcus sp. tested positive for phosphate solubilization, nitrogen fixation, ammonia production and induction of indole acetic acid. Overall, digestate may be successfully deployed as a safe biofertilizer when treated at suitable temperature and time for enhance plant growth. [ABSTRACT FROM AUTHOR]

Two general expansions of urban density models are used to account for directional bias in complex urban forms. These expansions can be applied to simple functions where density is continuously declining with distance, or to more complex functions where maximum density is reached at some distance from the urban center. This approach may be required for more realistic empirical analysis, such as accounting for the axial bias typical of most cities. [ABSTRACT FROM AUTHOR]

The article focuses on the issues related to environmental justice. One of the problems in doing research in the environmental justice area is sensitivity to criticism that often draws more heat than light. There are important issues in environmental justice and these are damaging with respect to minorities and the poor. Liam Downey has identified several key issues of concern. The point was that arbitrarily basing one's conclusion on one geographical scale while rejecting the findings at another geographical scale becomes a problems, especially when the conclusions differ at different geographical scales, as they appear to in Downey's study. There is another related but distinct issue about basing one's conclusion on a statewide rather than on an exclusively urban scale. This issue does not have so much to do with selecting the smallest spatial units of analysis, but with selecting the proper and appropriate geographical scale for the process of interest apart from the units of analysis with which it is analyzed.

FOOD security , *HIGH-income countries , *PSYCHOLOGICAL distress , *PSYCHOLOGICAL stress , *PSYCHOLOGICAL well-being - Abstract
Background: Numerous studies have established a correlation between Food Insecurity (FI) and diminished physical and psychological well-being. However, there is a lack of knowledge regarding this association among migrant and refugee populations. Migrants and refugees face difficulties, such as a lack of legal clarity and employment opportunities, which can exacerbate FI and psychological well-being issues. Therefore, the main goal of this study is to conduct a systematic review of the existing body of literature, followed by a meta-analysis of the results, where appropriate, to examine how common food insecurity is among migrants and refugees living in high-income countries and whether it might be linked to mental distress. Methods: The inclusion of studies will be contingent upon providing quantitative data on migrants and refugees in developed countries. This criterion encompasses all pertinent observational study designs and has been published in English. The review will specifically include cross-sectional, case-control, and cohort studies that utilize standardized and validated measurement tools for food insecurity (e.g., Food Insecurity Experience Scale) and psychological stress (e.g., 21-item Depression Anxiety and Stress Scale (DASS-21)), excluding non-standard or non-validated measures. A systematic search will be conducted across electronic databases such as Ovid Medline, Embase, SCOPUS, and Web of Science, containing peer-reviewed journal papers in health, psychology, and social sciences from January 1, 2008, to the present for relevant studies. Prevalence estimates will be generated using meta-analysis with a 95% CI, 95% prediction intervals, and I2 statistics for heterogeneity. The studies incorporated in the review will be analysed using meta-analysis, as deemed suitable for the characteristics of the data obtained. Discussion: This study has practical implications for policies and interventions, offering insights for evidence-based initiatives targeting food security and mental health among migrants and refugees, thus improving resource allocation.

Wastewater Based Surveillance (WBS) has emerged as a novel monitoring tool for tracking and estimating the dissemination of the Novel Coronavirus Disease 2019 (COVID-19) within communities. The goal of this review is to assess the factors that influence estimations of SARS-CoV-2 RNA concentration estimations in wastewater. A literature search was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis for Scoping Reviews (PRISMA-ScR) criteria in the electronic databases Scopus, PubMed, Google Scholar, and Medline. The overall quality, sample methodologies, quantification methods, and estimating approaches of selected papers were assessed. Our findings reveal that 16 out of 24 articles (67 %) focused on physiochemical analyses. This review showed that sampling strategies and laboratory methodologies play a crucial role in the detection of SARS-CoV-2 RNA in wastewater samples. Moreover, we found that WBS-based estimation of COVID-19 is influenced by several factors such as wastewater temperature, shedding rate, and population size. This review reveals that the identified parameters require adjustments to achieve optimum conditions that accurately predict community infections. Including these factors that influence the estimation of SARS-CoV-2 RNA concentration in wastewater is essential for developing effective public health strategies to combat the spread of COVID-19.
