Protocol for a quasiexperimental study testing the effectiveness of strengthening growth monitoring and promotion in community clinics for improving the nutritional status of under-two children in rural Bangladesh

INTRODUCTION

The Government of Bangladesh is implementing growth monitoring and promotion (GMP) through community clinics (CC) to improve the nutritional status of children. However, little primary evidence is available on the effectiveness of GMP when delivered through CCs. We aim to examine the effectiveness of GMP activities strengthened in CCs to improve the nutritional status of children under 2 years of age.

METHODS AND ANALYSIS

This is a quasiexperimental, two-arm, mixed methods study. In the intervention arm, a non-governmental organisation is providing support to strengthen GMP implementation in the 30 CCs. The comparison arm has no intervention to strengthen GMP implementation in the 30 CCs. Study participants will be under-two children and their caregivers, and CC service providers (community healthcare provider, CHCP). We will collect quantitative information on children and mothers' anthropometry, sociodemographic condition, food security, children's feeding practices, morbidity and vaccination history at baseline, and follow them up every third month thereafter for 12 months. We will collect qualitative information on (1) knowledge, skill and practice of CHCPs to implement GMP; (2) mothers/caregivers' perception, knowledge and experience of GMP from CCs; (3) experience and suggestions of programme managers about operational challenges and for improving quality of GMP service delivery; and (4) views of the concerned policy planners to strengthen GMP at the CC level. Qualitative information will be collected through key informant and in-depth interviews at baseline and endline. The primary outcome will be the change observed in length-for-age Z-score of children. A difference-in-difference and linear mixed effects analysis of quantitative data will be done. Thematic analysis will be conducted for qualitative information. Triangulation of data derived from different methods will be carried out.

ETHICS AND DISSEMINATION

This study received ethical approval from the Institutional Review Board of International Centre for Diarrhoeal Disease Research, Bangladesh, and results will be disseminated via peer-reviewed publications and conference presentations.

P5435Epigenetic modifications and gene expressions in Mybpc3 knockout mice

Background

DNA methylation and hydroxymethylation plays critical role in important biological processes, including differentiation of tissues in the embryo and cellular response to different diseases and diverse environmental factors. The epigenetic landscape in heart failure might be altered.

Purpose

Our objective was to determine how Mybpc3 deficiency, which produces hypertrophic cardiomyopathy, affects epigenetic landscape, gene expression, and regulation.

Methods

We generated and analysed genome-wide DNA methylomes and hydroxymethylomes from cardiac tissues of 12-week old Mybpc3−/− mice and littermate controls, and performed whole genome RNA sequencing (RNA-seq) for gene expression and validated the findings using qPCR.

Results

Single base resolution revealed overall lower 5-mC level in Mybpc3 deficient mice. In deficient mice, different genic regions including transcription start site, exons, and introns, had low levels of 5-mC. Although there was no overall difference in 5-hmC content, knockout mice had lower levels of 5-hmC in the distal part of the genes (last exon, transcription termination site, and 3'-flanking regions). The 5-hmC enrichment in the intronic regions was associated with higher gene expression, whereas, the presence of 5-mC in the 5'-flanking regions was associated with lower gene expression in both knockout and wildtype mice. Ingenuity pathway analysis (IPA) of differentially expressed genes revealed overrepresentation of genes involved in axonal-guidance pathway. Tet activity was downregulated in Mybpc3−/− mice, and it may explain the overall difference of 5-mC in deficient mice. We also observed that Mybpc3 ablation affected alternative splicing of Myh6 and Myh7.

Conclusion

This study establishes that knocking out of Mybpc3 changes epigenetic landscape in cardiac tissue, which is tightly linked to gene expression and regulation.

3D-printed Franz type diffusion cells

OBJECTIVE

Franz cells are routinely used to measure in vitro skin permeation of actives and must be inert to the permeant under study. The aim of the present work was to develop and manufacture transparent Franz-type diffusion cells using 3D printing. Printouts were then tested using a range of model active compounds. The study also aims to identify the critical 3D-printing parameters necessary for the process, including object design, choice of printing resin, printout curing and post-curing settings and introduction of model coatings.

METHODS

Transparent Franz cells were constructed using an online computer aided design program and reproduced with different stereolithography 3D printers. The two acrylate-based resins used for the fabrication process were a commercially available product and a polymer synthesised in-house. Comparative studies between glass and 3D-printed Franz cells were conducted with selected model actives: terbinafine hydrochloride (TBF), niacinamide (NIA), diclofenac free acid (DFA) and n-methyl paraben (MPB). In preliminary studies, MPB showed the lowest recovery when exposed to the receptor compartment of 3D printed cells. Consequently, in vitro permeation studies were carried out using only MPB with polydimethylsiloxane (PDMS) membrane.

RESULTS

A decrease in the amounts of selected compounds was observed for transparent 3D-printed Franz cells compared to glass cells. MPB showed the lowest recovery (53.8 ± 13.1%) when compared with NIA (74.9 ± 4.0%), TBF (81.5 ± 12.0%) and DFA (90.2 ± 12.9%) after 72 h. Permeation studies conducted using 3D-printed transparent cells with PDMS membrane also showed a decrease in MPB recovery of 51.4 ± 3.7% for the commercial resin and 94.4 ± 3.5% for the polymer synthesised in-house, when compared to glass cells. Although hydrophobic coatings were subsequently applied to the 3D-printed cells, the same reduction in MPB concentration was observed in the receptor solution.

CONCLUSION

Transparent Franz cells were successfully prepared using 3D printing and were observed to be robust and leak-proof. There are few resins currently available for preparation of transparent materials and incompatibilities between the actives investigated and the 3D-printed cells were evident. Hydrophobic coatings applied as barriers to the printed materials did not prevent these interactions.

Aflatoxin exposure in children living in Mirpur, Dhaka: data from MAL-ED companion study

Dietary exposure to aflatoxin is implicated in growth faltering of children. Despite the high burden of childhood stunting in urban Bangladesh, there are no data on long-term exposure to aflatoxin. This study aimed to explore aflatoxin exposure levels in a group of children followed longitudinally. The current study used data and biospecimens collected during 2010-2014 as part of the MAL-ED birth cohort study in an urban slum of Mirpur, Dhaka where children were followed from birth to 36 months. AFB1-lysine adduct concentrations were determined by isotope dilution mass spectrometry from plasma samples collected at 7, 15, 24, and 36 months of age. The limit of detection was 0.5 pg of AFB1-lys/mg albumin. In 744 plasma samples, the geometric mean of AFB1-lysine/mg albumin was 1.07 pg (range 0.04-123.5 pg/mg albumin). The proportion of children with detectable aflatoxin exposure was 10.1, 20.9, 17.9, and 61.7% for 7, 15, 24, and 36 months, respectively. Reduction in breastfeeding prevalence (80% at 24 months vs. 38% in 36 months) corresponded with the high-level detection of AFB1-lysine at the age of 36 months. AFB1-lysine concentrations were the highest at the end of monsoon. This study reveals that 62% of children in slum settlement were exposed to aflatoxin by the end of the third year of life. High aflatoxin exposure was detected at the end of rainy season and with the introduction of family food. These findings suggest interventions to ameliorate the problem of chronic aflatoxin exposure including childhood stunting.

Microbial Contamination of Handmade Sauce Used by Street Food Vendors in Jashore, Bangladesh

Background: Contaminated handmade street foods are often claimed to occur food-borne diseases, especially in developing countries. Therefore, considering the public health issue, this study was conducted to assess the microbial contamination of handmade sauce used by street food vendors in Jashore, Bangladesh. Methods: A total of 30 samples of Plum Sauce (PS) and Tomato Sauce (TS) were collected from Jashore district, Bangladesh. The quantitative microbial tests were done by dilution plate technique. Identification of particular bacterial group or species was performed using selective media. All the data related to microbial count were subjected to ANOVA test using SPSS version 21.0. Results: All the sauce samples contained viable Enterobacteriaceae cells; whereas 80% and 83.33% of the total samples were found to be contaminated with Salmonella spp. and Escherichia coli, respectively. Total viable bacterial cells found in the samples ranged from 1.2×103 to 4.2×109 Colony Forming Unit (CFU)/g. In addition, total Enterobacteriaceae and E. coli counts ranged from 30 to 2.0×107 and from 0 to 7.0×105 CFU/g, respectively. Although PS samples contained a higher amount of Enterobacteriaceae and E. coli compared to TS, no significant difference (p>0.05) was found. Conclusion: The consumption of street foods is of great concern in Bangladesh. Making the vendors aware of sanitary practices is too crucial that could be achieved through training of the vendors at the root level of the country. Furthermore, it is necessary to monitor the street foods frequently by the national authorities.

Serum Adipokines, Growth Factors, and Cytokines Are Independently Associated with Stunting in Bangladeshi Children

Growth in young children is controlled through the release of several hormonal signals, which are affected by diet, infection, and other exposures. Stunting is clearly a growth disorder, yet limited evidence exists documenting the association of different growth biomarkers with child stunting. This study explored the association between different growth biomarkers and stunting in Bangladeshi children. A quasi-experimental study was conducted among 50 stunted (length-for-age Z-score (LAZ) < -2 SD) and 50 control (LAZ ≥ -2 SD) children, aged 12-18 months, residing in a Bangladeshi slum. The enrolled stunted children received an intervention package, which included food supplementation for three months, psychosocial stimulation for six months, and routine clinical care on community nutrition center at the study field site. The controls received routine clinical care only. All children were clinically screened over the study period. Length, weight, fasting blood and fecal biomarkers were measured. All biomarkers levels were similar in both groups except for oxyntomodulin at enrolment. Leptin (adjusted odds ratio, AOR: 4.0, p < 0.01), leptin-adiponectin ratio (AOR 5.07 × 10⁸, p < 0.01), insulin-like growth factor-1 (IGF-1) (AOR 1.02, p < 0.05), and gamma interferon (IFN-γ) (AOR 0.92, p < 0.05) levels were independently associated with stunting at enrolment. Serum leptin, leptin-adiponectin ratio, interleukin-6 (IL-6), IL-10, tumor necrosis factor-alpha (TNF-α), and fecal alpha-1-antitrypsin (AAT) levels increased significantly (p < 0.001), while IFN-γ levels significantly decreased among stunted children after six months of intervention. Leptin, leptin-adiponectin ratio, IGF-1, and IFN-γ are independently associated with stunting in Bangladeshi children. This trial was registered at clinicaltrials.gov as NCT02839148.

Early childhood development and stunting: Findings from the MAL-ED birth cohort study in Bangladesh

Information on the association between stunting and child development is limited from low‐income settings including Bangladesh where 36% of children under‐ 5 are stunted. This study aimed to explore differences in early childhood development (ECD) between stunted (length‐for‐age z‐score [LAZ] < −2) and nonstunted (LAZ ≥ −2) children in Bangladesh. Children (n = 265) aged 6–24 months who participated in the MAL‐ED birth cohort study were evaluated by trained psychologists at 6, 15, and 24 months of age using the Bayley Scales of Infant and Toddler Development‐III; child length and weight were measured using standard procedures. ECD scores (z‐scores derived from cognitive, motor, language and socio‐emotional skills) were compared between stunted, underweight (weight‐for‐age z‐score < −2), and wasted (weight‐for‐length z‐score < −2) children, controlling for child age and sex and maternal age, education, body mass index (BMI), and depressive symptoms. Stunted children had significantly lower ECD scores than their nonstunted peers on cognitive (P = .049), motor (P < .001), language (P < .001) and social–emotional (P = .038) scales where boys had significantly lower fine motor skills compared with girls (P = .027). Mother's schooling and BMI were significant predictors of ECD. Similar to stunting, underweight children had developmental deficits in all domains (cognitive: P = .001; fine motor: P = .039, and P < .001 for both gross motor and total motor; expressive communication: P = .032; total language: P = .013; social–emotional development: P = .017). Wasted children had poor motor skills (P = .006 for the fine motor; P < .001 for both gross motor and total motor development) compared with the nonwasted peers. Early childhood stunting and underweight were associated with poor developmental outcomes in Bangladesh.

Validation and Application of Biocrates AbsoluteIDQ® p180 Targeted Metabolomics Kit Using Human Milk

Human-milk-targeted metabolomics analysis offers novel insights into milk composition and relationships with maternal and infant phenotypes and nutritional status. The Biocrates AbsoluteIDQ® p180 kit, targeting 40 acylcarnitines, 42 amino acids/biogenic amines, 91 phospholipids, 15 sphingolipids, and sum of hexoses, was evaluated for human milk using the AB Sciex 5500 QTRAP mass-spectrometer in liquid chromatography-tandem mass-spectrometry (LC-MS/MS) and flow-injection analysis (FIA) mode. Milk (<6 months lactation) from (A) Bangladeshi apparently healthy mothers (body mass index (BMI) > 18.5; n = 12) and (B) Bangladeshi mothers of stunted infants (height-for-age Z (HAZ)-score <-2; n = 13) was analyzed. Overall, 123 of the possible 188 metabolites were detected in milk. New internal standards and adjusted calibrator levels were used for improved precision and concentration ranges for milk metabolites. Recoveries ranged between 43% and 120% (coefficient of variation (CV): 2.4%-24.1%, 6 replicates). Milk consumed by stunted infants vs. that from mothers with BMI > 18.5 was lower in 6 amino acids/biogenic amines but higher in isovalerylcarnitine, two phospholipids, and one sphingomyelin (p < 0.05 for all). Associations between milk metabolites differed between groups. The AbsoluteIDQ® p180 kit is a rapid analysis tool suitable for human milk analysis and reduces analytical bias by allowing the same technique for different specimens. More research is needed to examine milk metabolite relationships with maternal and infant phenotypes.

Human Milk Metabolomics Using Biocrates AbsoluteIDQ® p180 Kit Assay (OR06-04-19)

Objectives

Targeted metabolomics are commercially available for human plasma, but not for human milk. However, metabolite analyses could provide a novel and efficient approach to understanding human milk composition and relationships to maternal and infant status.

Methods

Pooled human milk was used to evaluate and validate the Biocrates AbsoluteIDQ® p180 kit for human milk metabolomics (40 acylcarnitines, 42 acids/biogenic amines, 91 phospholipids, 15 sphingolipids, sum of hexoses) using an ABSciex 5500QTRAP mass spectrometer in LC-MS/MS and flow injection analysis (FIA) mode. In a feasibility study, milk collected <6 mo lactation from A) Bangladeshi healthy mothers (BMI >18.5, n = 12) and from B) mothers with stunted infants (HAZ-score < −2; n = 13) were analyzed.

Results

120 of the detectable 188 assay metabolites were found in the pooled milk, including all of the sphingolipids and amino acids. Additional internal standards (IS) were prepared for lysine and some biogenic amines for higher accuracy. Higher amounts of glutamate, taurine, and putrescine in milk required higher levels of calibrators than for plasma in LC-MS/MS mode. For metabolites of low abundance diluted calibrators (0.25 and 0.5) were added. FIA provided results for 94 of 146 metabolites above LOD without any carry-over. Metabolite recoveries (levels) varied between 64.1 and 127.0%. Intra-assay variations (6 replicates) for all detectable metabolites ranged between 3.4 and 18.4%. Human milk given to healthy compared to malnourished infants was higher in the amino acids citrulline, glutamate, glycine, and phenylalanine, and carnitine, while histamine and dodecanoylcarnitine were lower (Student's t-test, P < 0.05 for all).

Conclusions

The AbsoluteIDQ® p180 can be used for human milk application and thus allows the application of the same assay for both human plasma and milk, enhancing comparability of results by reducing analytical bias due to different analytical techniques.

Development and validation of a tool to assess appetite of children in low income settings

Reliable and validated tools for measuring appetite of children in South Asia are not available. This study aimed to develop and validate a tool for assessing appetite level of under-five children. Based on literature review and findings from focus group discussions (FGDs), an initial 27-item interview-based tool, the "Early Childhood Appetite and Satiety Tool (ECAST)" was developed in Bangladesh. Fourteen FGDs were carried out in rural and urban settings and constructs for inclusion were derived from the themes and coding of FGDs and appetite assessment tools used in Western contexts. For structural validation, the ECAST-27-was administered on 150 mothers/primary caregivers of children aged 6-59 months, living in urban and rural areas. To validate the association with other variables, the ECAST was administered on mothers of children aged 12-24 months in the community (N = 50), and two groups of wasted, hospitalized children (Weight-for-length, Z score <-2SD) [group1: twenty acutely ill children aged 6-59 months; group 2: twenty children in nutritional rehabilitation aged 18-24 months]. Reliability of ECAST was estimated using Cronbach's alpha and Pearson's correlation coefficient. Kaiser-Meyer-Olkin = 0.73 and the Bartlett's test of sphericity, χ²(253) = 755.791, p < 0.001 indicated that the raw data were suitable. Given the convergence of the Scree plot, Kaiser's criterion and dropping of cross loading items, a 16-item ECAST was produced with three sub scales: Appetite cue; Food responsiveness and Emotion and preference, which were internally valid and had good test-retest reliability (Cronbach's alpha 0.6 and test-retest reliability 0.797). Total ECAST scores of wasted children with good appetite were significantly higher from those with poor appetite (p = 0.004 and 0.001 for two wasted groups respectively). Results suggest that ECAST may provide a useful measure to assess the appetite level of under-five children.

Efficacy of Palonosetron as Antiemetic Prophylaxis for Post Operative Patients

Palonosetron is a new, potent and long-acting 5HT3-receptorsantagonist that had been approved by the FDA for use in postoperative nausea and vomiting (PONV) prophylaxis. The objective of this study was to investigate and compare the prophylactic effects of intravenously administered palonosetron, ondansetron and granisetron on prevention of postoperative nausea and vomiting after general anesthesia. This randomized double blind prospective clinical study was carried out in the Department of Anaesthesia, DMCH, Dhaka, Bangladesh from January 2014 to December 2015. A total of 102 patients who underwent laparoscopic cholecystectomy under general anesthesia, out of which patients who received Palonosetron were in Group A (n=34), patients who received Ondansetron were in group B (n=34) and patients who received Granisetron were in group C (n=34) and also the patients were selected randomly by lottery method. Statistical analyses of the results were obtained by using window based computer software devised with Statistical Packages for Social Sciences (SPSS-22). Nausea was found 3(8.8%) in group A, 8(23.5%) in group B and 6(17.6%) in group C. Vomiting was found 3(8.8%) in group A, 10(29.4%) in group B and 7(20.6%) in group C. Vomiting was significantly higher in group B compare with group A. For group B rescue anti-emetic injection motilon (metoclopramide hydrochloride) 5mg IV slowly was given. Palonosetron is effective prophylaxis against post operative nausea and vomiting.

Systematic Review of Tools and Methods to Measure Appetite in Undernourished Children in the Context of Low- and Middle-Income Countries

Child undernutrition has multifactorial causes, ranging from food insecurity to etiologies refractory to conventional nutritional approaches, such as infections, environmental enteric dysfunction, and other conditions that lead to systemic inflammation. Poor appetite may be an important symptom of these causes and may be a useful marker of an undernourished child's ability to recover. We conducted a systematic review to characterize the methods and tools to measure appetite among children <5 y old in low- and middle-income countries. A systematic search of 8 databases identified 23 eligible studies published since 1995. Thirteen described methods based on direct feeding observation or quantification of nutrient intake from caregiver report, 16 described tools that assessed caregiver perceptions of appetite, and 6 reported assessments in both categories. Four studies that gauged caregiver perceptions assessed multiple appetite domains, whereas 12 assessed 1 domain-often with a single question. Only 6 studies reported validation processes, the most common of which compared an observed test meal with daily energy intake. No studies reported the use of a method or tool that was validated in multiple cultural or linguistic contexts. Although dietary intake measures and observed feeding tests have shown validity in some contexts, they are resource intensive. Subjective caregiver questionnaires may offer a more efficient appetite evaluation method, but they have been evaluated less consistently. A rigorously developed and validated tool to rapidly assess child appetite is needed and could be best addressed by a questionnaire that leverages the multiple domains of appetite. The application of interventions that target causes of undernutrition that are not amenable to food-based interventions in clinical or research contexts could be facilitated by an efficient appetite screening tool to identify appetite-related causes of undernutrition and to monitor children's response to such interventions.

What have we learned from the time trend of mass shootings in the U.S.?

Little is known regarding the time trend of mass shootings and associated risk factors. In the current study, we intended to explore the time trend and relevant risk factors for mass shootings in the U.S. We attempted to identify factors associated with incidence rates of mass shootings at the population level. We evaluated if state-level gun ownership rate, serious mental illness rate, poverty percentage, and gun law permissiveness could predict the state-level mass shooting rate, using the Bayesian zero-inflated Poisson regression model. We also tested if the nationwide incidence rate of mass shootings increased over the past three decades using the non-homogenous Poisson regression model. We further examined if the frequency of online media coverage and online search interest levels correlated with the interval between two consecutive incidents. The results suggest an increasing trend of mass shooting incidences over time (p < 0.001). However, none of the state-level variables could predict the mass shooting rate. Interestingly, we have found inverse correlations between the interval between consecutive shootings and the frequency of on-line related reports as well as on-line search interests, respectively (p < 0.001). Therefore, our findings suggest that online media might correlate with the increasing incidence rate of mass shootings. Future research is warranted to continue monitoring if the incidence rates of mass shootings change with any population-level factors in order to inform us of possible prevention strategies.

Changes of Peak Expiratory Flow Rate in Adult Asthmatic Patient

Asthma is a common pulmonary disorder characterizerized by airway inflammation, airway- hyper reactivity, and reversible airflow obstruction. The classic triad of symptoms is wheezing, chronic episodic dyspnea and chronic cough. The prevalence of asthma increased steadily over the latter part of the last century, first in the developed and then in the developing world. The number of people with asthma in the world may be as high as 334 million. Asthma in Bangladesh appears to be a substantial public health problem: an estimated 11.6 million people including 4.1 million children suffer from asthma-related symptoms. A cross sectional study was conducted from January 1999 to August 1999 on 5642 Bangladeshi people and another same study carried out from November 2009 to April 2010 on 8088 subjects. In 1999 the prevalence of asthma was 6.9% whereas in 2010 it is 6.96%. Airway resistance is always increased during the asthmatic attack. Airways obstruction, such as that caused by asthma, results in a reduced and variable Peak Expiratory Flow Rate (PEFR). PEFR is classically reduced in asthma. Recent asthma guidelines recommended the assessment of severity levels based on the most severe symptoms and peak expiratory flow rate. This descriptive type of cross-sectional study was done to find the changes of Peak expiratory flow rate in adult asthmatic patients and carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2014 to January 2016. Fifty (50) male and 50 (fifty) female adult asthmatic patients aged 18-60 years were included in the study group. They are enrolled from the Department of Medicine, Mymensingh Medical College, Mymensingh, Bangladesh and also from locality. For comparison age matched 50 male and 50 female apparently healthy persons were also studied as control. PEFR was estimated by Wright's Peak flow meter. For statistical analysis unpaired student's 't' test was used. Mean PEFR were significantly decreased in study group in comparison to control group and the result was statistically significant (p<0.001). From this study, it may be concluded that peak expiratory flow rate was decreased in asthmatic patient and there was a significant relation of decline lung function.

Rescue of an Axillary-Axillary Arteriovenous Graft not Amenable to Endovascular Intervention by Formation of an Axillary Loop: A Case Report

Central venous obstruction associated with a distal arteriovenous fistula can result in massive swelling of the affected extremity and venous hypertension. We present the surgical rescue of an axillary-axillary arterio-venous access ((necklace graft) between the left axillary artery to the contralateral axillary vein), compromised by central venous stenosis, by conversion into an arteriovenous axillary loop graft (AVALG) as an additional “exotic” grafting procedure in the anterior chest. This procedure resulted in the salvage of the patient's access and rapid resolution of the associated upper extremity swelling.

Current Trends of Using Systemic Antifungal Drugs and their Comparative Efficacy in Tinea Corporis and Tinea Cruris in Outpatient Department of Dermatology in a Tertiary Level Hospital

Tinea corporis & cruris are one of the earliest known fungal infection and are very common throughout the world. Although tinea corporis and tinea cruris does not cause mortality but causes morbidity and poses a major health problem. This study was conducted to evaluate the Comparative Efficacy of Terbinafine and Fluconazole in the Treatment of Tinea corporis and Tinea cruris. This cross sectional comparative type of analytical study was carried out at the department of Pharmacology & Therapeutics with collaboration of Dermatology and Venereology in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2016 to December 2016. In this study 168 newly diagnosed Tinea corporis and Tinea cruris patient was purposively selected where pattern of comparative efficacy of terbinafine and fluconazole were analyzed. Among 168 patients most of the patients presented with tinea corporis (58.33%). Most patients belong to 21-30 years age group. Male female ratio in this study was 1.15:1. In this study 143 patients were treated by fluconazole 50mg once daily for 4 weeks and 25 patients were treated by terbinafine 250 mg once daily for 4 weeks. After 4 weeks, improvement rate by fluconazole was 86.02% and terbinafine 96.00%. The clinical score of both groups after 4th week of treatment, there was slight more reduction of clinical score in terbinafine using group than fluconazole using group. The difference between these two clinical score was not statistically significant (p>0.05). Although no significant difference was observed between these two groups of patient in clinical aspect, but due to its lower price and availability in the hospital, it is suggested that fluconazole is more suitable for the treatment of tinea corporis and tinea cruris.

Interaction between Hypertension and Asthma in Adult

Asthma has been defined as a chronic inflammatory disorder of the airways that is associated with recruitment of inflammatory cells and the clinical development of wheezing, shortness of breath, chest tightness, and cough. The prevalence of asthma increased steadily over the latter part of the last century, first in the developed and then in the developing world. Current estimates suggest that asthma affects 300 million people worldwide, with a predicted additional 100 million people affected by 2025. This cross sectional study was conducted from January 1999 to August 1999 on 5642 Bangladeshi people and another same study carried out from November 2009 to April 2010 on 8088 subjects. In 1999 the prevalence of asthma was 6.9% whereas in 2010 it is 6.96%. Both asthma and hypertension are spastic disorders of smooth muscle, there is the similarities between these two diseases may predispose the individuals with one disease to the other. This descriptive type of cross-sectional study was done to find the Interaction between hypertension and asthma in adult and carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2014 to January 2016. Fifty (50) male and fifty (50) female adult asthmatic patients aged 18-60 years were included in the study group. They are enrolled from the Department of Medicine, Mymensingh Medical College, Mymensingh and also from locality. For comparison age matched 50 male and 50 female apparently healthy persons were also studied as control. Blood pressure was estimated by auscultatory method by sphygmomanometer. For statistical analysis unpaired student's 't' test was used. Mean blood pressure were significantly increased in study group in comparison to control group and the result was statistically significant (p<0.001). The study findings showed a high prevalence of hypertension among asthmatic patients than non asthmatic healthy persons. From this study, it may be concluded that hypertension and asthma are closely connected.

Evidence-based approaches to childhood stunting in low and middle income countries: a systematic review

OBJECTIVE

We systematically evaluated health and nutrition programmes to identify context-specific interventional packages that might help to prioritise the implementation of programmes for reducing stunting in low and middle income countries (LMICs).

METHODS

Electronic databases were used to systematically review the literature published between 1980 and 2015. Additional articles were identified from the reference lists and grey literature. Programmes were identified in which nutrition-specific and nutrition-sensitive interventions had been implemented for children under 5 years of age in LMICs. The primary outcome was a change in stunting prevalence, estimated as the average annual rate of reduction (AARR). A realist approach was applied to identify mechanisms underpinning programme success in particular contexts and settings.

FINDINGS

Fourteen programmes, which demonstrated reductions in stunting, were identified from 19 LMICs. The AARR varied from 0.6 to 8.4. The interventions most commonly implemented were nutrition education and counselling, growth monitoring and promotion, immunisation, water, sanitation and hygiene, and social safety nets. A programme was considered to have effectively reduced stunting when AARR≥3%. Successful interventions were characterised by a combination of political commitment, multi-sectoral collaboration, community engagement, community-based service delivery platform, and wider programme coverage and compliance. Even for similar interventions the outcome could be compromised if the context differed.

INTERPRETATION

For all settings, a combination of interventions was associated with success when they included health and nutrition outcomes and social safety nets. An effective programme for stunting reduction embraced country-level commitment together with community engagement and programme context, reflecting the complex nature of exposures of relevance.

Venous thromboembolism in adult elective spinal surgery

Aims

To evaluate the incidence of primary venous thromboembolism (VTE), epidural haematoma, surgical site infection (SSI), and 90-day mortality after elective spinal surgery, and the effect of two protocols for prophylaxis.

Patients and Methods

A total of 2181 adults underwent 2366 elective spinal procedures between January 2007 and January 2012. All patients wore anti-embolic stockings, mobilised early and were kept adequately hydrated. In addition, 29% (689) of these were given low molecular weight heparin (LMWH) while in hospital. SSI surveillance was undertaken using the Centers for Disease Control and Prevention criteria.

Results

In patients who only received mechanical prophylaxis, the incidence of VTE was 0.59% and that of SSI 2.1%. In patients who were additionally given LMWH, the incidence of VTE was 0% and that of SSI 0.7%. The unadjusted p-value was 0.04 for VTE and 0.01 for SSI. There were no cases of epidural haematoma or 90-day mortality in either group. When adjusted for case-mix, LMWH remained a significant factor (p = 0.006) for VTE, but not for SSI.

Conclusion

A peri-operative protocol involving mechanical anti-embolism stockings, adequate hydration, and early post-operative mobilisation is effective in significantly reducing the incidence of VTE. The addition of LMWH is safe in patients at higher risk of developing VTE. Cite this article: Bone Joint J 2017;99-B:1204–9.
