Women's awareness, knowledge, attitudes, and behaviours towards nutrition and health in Pakistan: Evaluation of kitchen gardens nutrition program.

INTRODUCTION: Vulnerability to malnutrition is very high with low-income women and their children in rural Balochistan with contributing factors including lack of awareness about proper nutrition, low literacy, scarcity of vegetables and fruit, and low purchasing power of households. The Food and Agriculture Organization's kitchen garden program provides resources to improve nutrition and health knowledge and promote healthy eating practices. The objective of this study was to assess nutrition and health awareness, knowledge, attitudes, behavioural intentions/behaviours (AKAB) of women who attended the kitchen garden program and trainings. MATERIALS AND METHODS: A community based cross-sectional survey (N = 209) using a two-stage cluster sampling method was used to select households with survey participants being mothers with children under five years of age. A pretested questionnaire was administered via face-to-face surveys by trained enumerators in two districts of Balochistan province of Pakistan. Nutrition and health AKAB were constructed indices. Chi-square tests compared statistical differences in AKAB by women attending against a control group who did not-attend kitchen garden interventions. Binary logistic regression analyses were performed to assess kitchen garden program outcomes against key AKAB indicators, while adjusting for covariates. RESULTS: Significant differences (p<0.001) were identified between intervention and control groups with women attending kitchen garden being more aware of the components of kitchen garden (65.8% vs 36.8%), and more knowledgeable about causes of illnesses caused by poor nutrition including, iron deficiency anemia, pregnancy, and unborn child health complications, compared to women not attending kitchen gardens program. Logistic regression analysis identified women attending kitchen gardens also had higher odds of being more knowledgeable (OR = 1.59, 95%CI 1.27-1.99, p<0.001), having improved attitudes (OR = 4.86, 95%CI 2.77-8.53, p <0.001), and behavioural intentions/behaviours (OR = 1.98, 95%CI 1.26-3.12, p = 0.003) towards improved nutrition and health. CONCLUSIONS: Substantial opportunities exist for achieving improved nutrition and health outcomes with vulnerable groups in Balochistan, through greater participation in kitchen gardens behavioural change programs and interventions. As part of scaling-up efforts, academically rigorous project evaluations should be institutionalized for continuous improvement of nutrition programs to address micronutrient deficiencies in rural communities.

Histone deacetylase inhibitors enhance oncolytic herpes simplex virus therapy for malignant meningioma.

Approximately 20% of meningiomas are not benign (higher grade) and tend to relapse after surgery and radiation therapy. Malignant (anaplastic) meningioma (MM) is a minor subset of high-grade meningioma that is lethal with no effective treatment options currently. Oncolytic herpes simplex virus (oHSV) is a powerful anti-cancer modality that induces both direct cell death and anti-tumor immunity, and has shown activity in preclinical models of MM. However, clinically meaningful efficacy will likely entail rational mechanistic combination approaches. We here show that epigenome modulator histone deacetylase inhibitors (HDACi) increase anti-cancer effects of oHSV in human MM models, IOMM-Lee (NF2 wild-type) and CH157 (NF2 mutant). Minimally toxic, sub-micromolar concentrations of pan-HDACi, Trichostatin A and Panobinostat, substantively increased the infectability and spread of oHSV G47Δ within MM cells in vitro, resulting in enhanced oHSV-mediated killing of target cells when infected at low multiplicity of infection (MOI). Transcriptomics analysis identified selective alteration of mRNA processing and splicing modules that might underlie the potent anti-MM effects of combining HDACi and oHSV. In vivo, HDACi treatment increased intratumoral oHSV replication and boosted the capacity of oHSV to control the growth of human MM xenografts. Thus, our work supports further translational development of the combination approach employing HDACi and oHSV for the treatment of MM.

Healthy lifestyle as a preventive measure against victimization among school-going adolescents.

BACKGROUND: Bullying and violence are problems of aggression in adolescents. Healthy lifestyle practices are common health promotion approaches in school settings; however, their association with aggressive behaviours in school-going adolescents is less explored. AIMS: This study examined the associations of healthy lifestyle behaviours including good hygiene, physical activity, recommended diet and refrainment from tobacco use with bully victimization and violence among adolescents. METHODS: Data were obtained from the Global School Health Survey conducted in Pakistan (2009). The study population consisted of school-going adolescents aged 13 to 15 years. We constructed our final dataset using information from 4102 participants. Association of healthy lifestyle behaviours with bully victimization and violence experience were assessed using multivariate logistic regression. RESULTS: Results indicate lower odds of being bullied (good hygiene: OR = 0.62, 95% CI 0.50-0.76, P <0.001; physical activity: OR=0.55, 95% CI 0.40-0.75, P <0.001; abstinence from tobacco: OR=0.43, 95% CI 0.30-0.63, P <0.001) and lower odds of violence (good hygiene: OR=0.68, 95% CI 0.55-0.84, P <0.001; physical activity: OR=0.55, 95% CI 0.43-0.71, P <0.001; abstinence from tobacco: OR=0.48, 95% CI 0.32-0.72, P <0.001), after controlling for socio-demographic and potential confounding factors. CONCLUSIONS: Our study supports the significance of healthy lifestyle as a preventive measure against victimization. Anti-bullying programmes focusing on social-emotional skill development may also consider promotion of healthy lifestyle behaviours among adolescents, aiming at reducing victimization and its related consequences.

Estimates of past and future time trends in age-specific breast cancer incidence among women in Karachi, Pakistan: 2004-2025.

BACKGROUND: The current demographic trends indicate that breast cancer will pose an even greater public health concern in future for Pakistan. Details on the incidence, disease severity and mortality in respect of breast cancer are limited and without such data, therefore, future health policies or systems in respect of this disease cannot be strategically planned or implemented. The aim of this study was to examine past trends of age-specific breast cancer incidence rates (2004-2015), and to estimate the future volume of breast cancer cases in Karachi through the year 2025. METHODS: Two statistical methods, namely the functional time series models and the log-linear regression model were used; additionally, their real forecasting efficacy in epidemic time series was also evaluated. RESULTS: In the past, women aged 60-64 years had the highest overall breast cancer incidence rates, while from 2016 to 2025, large increases in breast cancer rates among women aged 50 to 64 years are expected. The total projected breast cancer incidence will increase by approximately 23.1% in 2020 to 60.7% in 2025. Cases of breast cancer diagnosed in younger women, aged 30-34 years, will increase from 70.7 to 130.6% in 2020 and 2025 relative to 2015. CONCLUSIONS: The breast cancer incidence appeared to have been rising more rapidly among post-menopausal women (aged 55 to 59), while a stable increase in incidence in the youngest age group (15-29 years) of women is expected. The results also infer an expected increase in incidence cases of breast cancer among middle aged women in Karachi, Pakistan. An increase in the number of incident cases of cancer has implications for understanding the health-care needs of growing population and the subsequent demands on health-care system.

Areca Nut Chewing and the Risk of Re-hospitalization and Mortality Among Patients With Acute Coronary Syndrome in Pakistan.

OBJECTIVES: Areca nut is widely consumed in many parts of the world, especially in South and Southeast Asia, where cardiovascular disease (CVD) is also a huge burden. Among the forms of CVD, acute coronary syndrome (ACS) is a major cause of mortality and morbidity. Research has shown areca nut chewing to be associated with diabetes, hypertension, oropharyngeal and esophageal cancers, and CVD, but little is known about mortality and re-hospitalization secondary to ACS among areca nut users and non-users. METHODS: A prospective cohort was studied to quantify the effect of areca nut chewing on patients with newly diagnosed ACS by categorizing the study population into exposed and non-exposed groups according to baseline chewing status. Cox proportional hazards models were used to examine the associations of areca nut chewing with the risk of re-hospitalization and 30-day mortality secondary to ACS. RESULTS: Of the 384 ACS patients, 49.5% (n=190) were areca users. During 1-month of follow-up, 20.3% (n=78) deaths and 25.1% (n=96) re-hospitalizations occurred. A higher risk of re-hospitalization was found (adjusted hazard ratio [aHR], 2.05; 95% confidence interval [CI], 1.29 to 3.27; p=0.002) in areca users than in non-users. Moreover, patients with severe disease were at a significantly higher risk of 30-day mortality (aHR, 2.77; 95% CI, 1.67 to 4.59; p<0.001) and re-hospitalization (aHR, 2.72; 95% CI, 1.73 to 4.26; p<0.001). CONCLUSIONS: The 30-day re-hospitalization rate among ACS patients was found to be significantly higher in areca users and individuals with severe disease. These findings suggest that screening for a history of areca nut chewing may help to identify patients at a high risk for re-hospitalization due to secondary events.

Maternal depressive symptoms and child nutritional status: A cross-sectional study in socially disadvantaged Pakistani community.

Malnutrition is a primary cause of child morbidity and mortality. The effects of maternal depressive symptoms on children's health, especially their nutritional status, have received less attention in developing countries but needs to be evaluated to understand the public health implications of maternal depression. The aim of the current study was to investigate the association between maternal depressive symptoms and children's nutritional status using data from low socioeconomic community in Pakistan. Maternal depressive symptoms defined as Aga Khan University Anxiety and Depression Scale score of 20 or greater was assessed for mothers with children under two years of age. Logistic regression models estimated the association between maternal depressive symptoms and stunting and underweight. Of 325 mothers, 40% scored positive on the depressive scale. The prevalence of stunting and underweight in children under two years was 36.6% and 35.4%, respectively. Maternal depressive symptoms were significantly associated with children being stunted and underweight. Mothers with depressive symptoms were more than three times likely to have stunted (odds ratio (OR) 3.15, 95% confidence interval (CI) 1.91-5.18, p value < .001) and underweight (OR 3.26, 95% CI 1.99-5.34, p value < .001) children compared to non-depressed mothers. Maternal-related factors such as poor education, unemployment, and low household income were found to be significantly associated with higher odds of children's short stature and underweight.

Nutritional and lifestyle risk behaviors and their association with mental health and violence among Pakistani adolescents: results from the National Survey of 4583 individuals.

BACKGROUND: Unhealthy behaviors are associated with mental health problems and violence in adolescents, yet their combined association has been understudied. Using the Global School Health Survey, this study examined the association between combined unhealthy behaviors (including fast food, soft drink, smoking, other tobacco products and physical inactivity) and anxiety, suicidal ideation and involvement in physical fight among Pakistani adolescents. METHODS: Data were obtained from the Global School Health Survey conducted in Pakistan (2009). The study population consisted of school going adolescents aged 13 to 15 years. Association of combined unhealthy behaviors with anxiety, suicidal ideation and involvement in physical fight were studied through secondary analysis. We used univariate and multivariate logistic regression analysis by complex sample method, accounting for cluster sampling technique used for data collection. RESULTS: Of the total 4583 students, weighted percentage and unweighted count for one, two, three and four or more unhealthy behaviors was 39.4% (n = 1770), 22.1% (n = 963), 5.9% (n = 274) and 1.2% (n = 62) respectively. The weighted prevalence for anxiety, suicidal ideation and involvement in physical fight were 8.4%, 7.3% and 37.4% respectively. The results of multivariate logistic regression analysis after adjustment showed that students who had four or more unhealthy behaviors had higher odds of; being anxious (OR 2.45, 95%CI 1.31-4.59, p value 0.004), suicide ideation (OR 4.56, 95%CI 2.58-8.07, p value <0.001) and being involved in physical fight (OR 3.15, 95% CI 1.63-6.08, p value <0.001) as compared to those who had not adopted any unhealthy behaviors. CONCLUSIONS: This study suggests that the co-occurrence of unhealthy behaviors is associated with anxiety, suicidal ideation and physical fight among adolescents. These findings should be considered when developing interventions to combat detrimental outcomes of unhealthy behaviors during adolescence.

PAX4 enhances beta-cell differentiation of human embryonic stem cells.

BACKGROUND: Human embryonic stem cells (HESC) readily differentiate into an apparently haphazard array of cell types, corresponding to all three germ layers, when their culture conditions are altered, for example by growth in suspension as aggregates known as embryoid bodies (EBs). However, this diversity of differentiation means that the efficiency of producing any one particular cell type is inevitably low. Although pancreatic differentiation has been reported from HESC, practicable applications for the use of beta-cells derived from HESC to treat diabetes will only be possible once techniques are developed to promote efficient differentiation along the pancreatic lineages. METHODS AND FINDINGS: Here, we have tested whether the transcription factor, Pax4 can be used to drive the differentiation of HESC to a beta-cell fate in vitro. We constitutively over-expressed Pax4 in HESCs by stable transfection, and used Q-PCR analysis, immunocytochemistry, ELISA, Ca(2+) microfluorimetry and cell imaging to assess the role of Pax4 in the differentiation and intracellular Ca(2+) homeostasis of beta-cells developing in embryoid bodies produced from such HESC. Cells expressing key beta-cell markers were isolated by fluorescence-activated cell sorting after staining for high zinc content using the vital dye, Newport Green. CONCLUSION: Constitutive expression of Pax4 in HESC substantially enhances their propensity to form putative beta-cells. Our findings provide a novel foundation to study the mechanism of pancreatic beta-cells differentiation during early human development and to help evaluate strategies for the generation of purified beta-cells for future clinical applications.

Human embryonic stem cells: possibilities for human cell transplantation.

Human embryonic stem (ES) cells serve as a potentially unlimited renewable source for cell transplantation targeted to treat several diseases. One advantage of embryonic stem (ES) cells over other stem cells under research is their apparently indefinite self-renewal capacity if cultured appropriately, and their ready differentiation into various cell phenotypes of all three germ layers. To date, a number of studies have reported the derivation of specific functional derivatives from human ES cells in vitro. While there have been clinical trials of human embryonal carcinoma (EC) cell-derived neurons in humans there has been no attempt as yet using human ES cell derivatives. However, the latter have been transplanted into recipient animals. In some cases ES-derived cells were shown to undergo further maturation, displayed integration with host tissue and even ameliorated the disease condition in the animal model. Recently, it has been reported that human ES cells can be genetically manipulated. Such procedures could be used to direct differentiation to a specific cell type or to reduce graft rejections by the modification of immune responses. This review highlights some of the recent advances in the field and the challenges that lie ahead before clinical trials using ES-derived cells can be contemplated.
