Effect of a short message service intervention on excessive gestational weight gain in a low-income population: a randomized controlled trial

Objectives: The objective of this trial was to investigate the effect of educational short message service (SMS), or text messages, on excessive gestational weight gain (GWG) in a low-income, predominantly overweight/obese population. Methods: Participants (n = 83) were mostly overweight/obese women recruited at Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) clinics on the island of O’ahu, Hawai’i at 15–20 weeks gestational age. The intervention group received SMS on nutrition and physical activity during pregnancy designed to help them meet Institute of Medicine (IOM) guidelines for GWG and American College of Obstetricians and Gynecologists guidelines for exercise, respectively. The control group received SMS about general health topics during pregnancy, excluding nutrition and physical activity. Both groups received one text message per week for eighteen weeks. GWG was defined as the difference between the last self-reported weight taken before delivery and participants’ self-reported weight before pregnancy. Differences between study groups were examined using t-tests and Chi-square tests. Linear regression models were used to examine association of GWG with study group and other factors. Results: GWG was similar (p = 0.58) in the control group (14.1 ± 11.4 kg) and the intervention group (15.5 ± 11.6 kg). The percentage of participants exceeding IOM guidelines for GWG was similar (p = 0.51) in the control group (50.0%, n = 17) and the intervention group (60.5%, n = 23). Conclusions: GWG was not significantly different between intervention and control groups. Trials that begin earlier in pregnancy or before pregnancy with longer intervention durations and varying message frequency as well as personalized or interactive messages may be needed to produce significant improvements

Impact of digital financial inclusion on ASEAN banking stability: implications for the post-Covid-19 era

Purpose: This paper aims to investigate how digital financial inclusion (DFI) can be a potential factor to maintain banking stability in Association of Southeast Asian Nations (ASEAN) countries and whether the relationship could bring a possible implication for the post-Covid-19 pandemic era. Design/methodology/approach: Using an unbalanced panel data of 213 banks of 4 ASEAN countries, the study has deployed principal component analysis, ordinary least square, two-step dynamic system generalised method of moments and panel corrected standard errors techniques. Findings: The empirical study finds that the full-fledged application of DFI accelerates the ASEAN banking stability which not only decreases the default risk of the banks but also upturns the financial mobility in the region. The results also suggest that ASEAN banks are, with the implementation of DFI, likely to uphold the banking sector stability by reducing liquidity crisis and non-performing loans during and in the post-Covid-19 era. Therefore, accelerating digital finance in ASEAN countries is considered as one of the significant means for the banking sector stability that subsequently leads to economic and financial resilience even in the face of any crises. Originality/value: Prevailing studies have mostly investigated the association between financial inclusion and banking stability in different contexts. However, this study is unique to empirically investigate the association between DFI and the ASEAN banking stability

Development of economical maximum power point tracking system for solar cell

Photovoltaic (PV) power generation system operates under various isolation conditions, which may generate several maximum output power points on the I-V curve of the PV array and raises serious problem on Maximum Power Point Tracking (MPPT) control of the system. This research concerned the design of MPPT for photovoltaic system by using PIC controller. A MPPT unit is developed for the optimum coupling of a Photovoltaic Panel (PVP) to the battery (load)through a controlled Buck type dc-dc converter which has made the difference from the past MPPT techniques and made it cost effective. The system has high-efficiency, lower-cost and low-power consumption. Moreover it permits easy modifications. This system operates at its maximum power generation with increasing the PV output power by as much as 32-36%. This study includes the theoretical aspects and experimental results of the proposed method

Evaluation of Neolamarckia cadamba (Roxb.) bosser leaf extract on glucose tolerance in glucose-induced hyperglycemic mice

Neolamarckia cadamba (Rubiaceae) leaf is used in folk medicine of Bangladesh for the treatment of diabetes, but so far no scientific study has been done which may support its use in traditional medicine. The present study was carried out to evaluate the possible glucose tolerance efficacy of methanolic extract of Neolamarckia cadamba leaf using glucose-induced hyperglycemic mice. The extract at different doses was administered one hour prior to glucose administration and blood glucose level was measured after two hours of glucose administration (p.o.) using glucose oxidase method. The statistical data indicated significant oral hypoglycemic activity on glucose-loaded mice at the two highest doses of 200 and 400 mg extract per kg body weight. Maximum anti-hyperglycemic activity was shown at 400 mg per kg body weight, which was comparable to that of , glibenclamide (10 mg/kg). The methanolic extract of leaf of Neolamarckia cadamba had beneficial effects in reducing the elevated blood glucose level of hyperglycemic mice.Keywords: Neolamarckia cadamba; Hypoglycemic activity; Serum glucose level; Glibenclamid

Islamic banking stability amidst the COVID-19 pandemic: the role of digital financial inclusion

Purpose: This paper aims to explore the role of digital financial inclusion (DFI) in stabilizing the Islamic banking sector amidst the current COVID-19 pandemic. Design/methodology/approach: This study has used the Panel-Corrected Standard Errors (PCSE), Two-Stage Panel Least Squares-Instrumental Variables (2SLS-IV) and Two-Step System Generalized Method of Moments (2SGMM) dynamic panel estimation method to investigate the DFI-Islamic banking stability nexus using an unbalanced panel data of 65 Islamic banks from six countries over the period 2011–2020. Findings: The result suggests that greater implementation of DFI promotes Islamic banking stability, which reduces the default risk of the banks in the studied region. Consequently, incorporating DFI into the Islamic banking sector encourages inclusive economic growth that can keep the financial sector sustainable even in a crisis period like the current COVID-19 pandemic. Originality/value: Unlike previous studies, the authors have focused mainly on DFI and the Islamic banking sector. This is one of the first to explore how DFI contribute to the stability and productivity of the Islamic banking sector during the pandemic. Also, this study provides fresh evidence on how the supply and demand side of DFI impact Islamic banking stability

Does audit quality moderate the impact of environmental, social and governance disclosure on firm value? Further evidence from Egypt

Purpose – This paper aims to examine the impact of environmental, social and governance (ESG) disclosure and firm value (FV), as well as, pinpoints the role of the audit quality (AQ) as a moderating variable on such impact; where the authors hypothesize that AQ modulates the relationship between ESG disclosure and the FV. Design/methodology/approach – Data of a sample of firms listed on the Egyptian Stock Exchange Market (EGX) were collected over the period of 2017–2021 and analyzed using the regression and 2SLS models. Findings – The results suggested that: (1) the ESG has a significant positive impact on the FV in the EGX, and (2) AQ has a significant impact, as a moderating variable, on the relationship between ESG disclosure and FV. Research limitations/implications – The findings would help the Egyptian market authorities in realizing the importance of integrating ESG information within the financial reports of the listed firms. The findings could also help in developing effective disclosure procedures to provide shareholders with useful information. Originality/value – This paper contributes to the literature regarding the ESG disclosure components and the FV value by considering AQ in testing such relationship

In-vitro investigation of biofilm-specific resistance and virulence of biofilm-forming uropathogenic Escherichia coli

Uropathogenic Escherichia coli (UPEC) is the primary etiologic agent of urinary tract infections (UTIs). This study aimed to investigate the difference in antimicrobial susceptibility of UPEC isolates in the planktonic and biofilm states. Important virulence factors were also evaluated. The minimum inhibitory concentrations (MICs) were determined and recorded as 0.5-64 μg/ ml for amikacin, 0.5-64 μg/ ml for cefotaxime, 0.25-64 μg/ ml for cefepime, 0.25-16 μg/ ml for meropenem, and 0.125-32 μg/ ml for ciprofloxacin. Biofilm-specific resistance was assessed using the minimum biofilm eradication concentration (MBEC). The obtained results for MBEC were: 8-512 μg/ ml for amikacin, 32-512 μg/ ml for cefotaxime, 8-512 μg/ ml for cefepime, 4-256 μg/ ml for meropenem, and 4-128 μg/ ml for ciprofloxacin. The virulence factors were evaluated using suitable phenotypic techniques. Our findings revealed a significant enhancement in the antimicrobial resistance after biofilm formation. The MBEC values were higher than the MIC values by 2-128 folds for amikacin, 2-256 folds for cefotaxime, 2-64 folds for cefepime, 8-128 folds for meropenem, and 4-128 folds for ciprofloxacin. The swimming and swarming motilities demonstrated a significant positive correlation (rs = 0.506, P< 0.001). Protease production analysis revealed a large variation, with the weak biofilm-producing isolates EW2 and EW15 displaying the largest zone diameters of 39 mm and 33 mm; respectively. We have also evaluated the distribution and levels of siderophore production, which were significantly associated with meropenem resistance. Finally, this study underscores the importance of considering biofilm formation in UPEC treatment and emphasizes the need for therapeutics targeting these biofilms

Assessment of Food Safety Knowledge, Attitudes and Practices of Food Service Staff in Bangladeshi Hospitals: A Cross-Sectional Study.

Food safety knowledge, attitudes and practices among hospital food service staff are crucial in the prevention of foodborne disease outbreaks, as hospitalized patients are more vulnerable to potential hazards. This study, therefore, sought to assess the food safety knowledge, attitudes and practices of food service staff in Bangladeshi hospitals. A cross-sectional study was conducted among 191 food service staff from seven different hospitals in Dhaka and Chattogram from October 2021 to March 2022 using pretested questionnaires. Multiple linear regression was used to identify the factors associated with the food safety knowledge, attitudes and practices. The findings showed moderate knowledge but high levels of attitudes and practices of food safety among hospital food handlers. Food safety knowledge was significantly higher among males, participants from private hospitals and participants working in a hospital that had a food service supervisor and dietitian in charge of food service operations. Moreover, participants from private hospitals and participants working in a hospital that had a food service supervisor and dietitian in charge of food service operations had more positive attitudes and better practices regarding food safety. Hospital management should consider these factors for enhancing food handlers' knowledge and increase training and supervision on food safety practices to reduce foodborne diseases and outbreaks

The Association Between Bangladeshi Adults’ Demographics, Personal Beliefs, and Nutrition Literacy: Evidence From a Cross-Sectional Survey

Background: Poverty and health illiteracy, combined with inappropriate systems to track disease and infection rates, contribute to children-and-mothers’ poor adherence to nutrient-rich foods intake in Bangladesh. Although risk factors for child and pregnant women malnutrition have been explored, the relationship between Bangladeshi adults’ nutrition literacy and their demographics and personal beliefs remains unknown. The purpose of this study was to examine the association between adults’ nutrition literacy, demographics and personal beliefs in a large sample of Bangladeshi adults. Methods: Four hundred adults from two districts (Dhaka and Chattogram) of Bangladesh participated in a cross-sectional survey. Data were collected by interviews using a structured questionnaire containing the Nutrition Literacy Scale. Multiple linear regression models were employed to analyze associations between nutrition literacy and related factors. Results: The mean nutrition literacy score was 21.6 (SD: 3.7; range: 11–32) on a scale of 32. Multiple linear regression revealed that being a businessman (β = 1.66, p = 0.013) or private employee (β = 1.08, p = 0.030), having a higher family income (β = 1.17, p = 0.009), and a higher educational level were positively associated with higher nutrition literacy scores compared to their counterparts. Participants who had ever completed a nutrition-related course (β = 4.95, p < 0.001), and who perceived themselves as having a need for accessing nutrition-related information were positively associated with the higher nutrition literacy compared to their counterparts. Conclusion: Findings from this study suggest the need for an integrated response plan involving educational interventions and accessible dietary plans targeting adult populations to enhance their nutritional literacy
