RESUMO

Numerous cultivars of chili are grown in Bangladesh for their nutritional and sensory attributes, serving as both spices and food items. Among many, indigenous chili cultivars in Bangladesh include Sada Akshi, Kajini, Dhani, and Naga are the important ones. The functional qualities of chili peppers are attributed to the plentiful presence of bioactive substances. Consequently, this study aimed to determine the variations in bioactive compounds, antioxidant activities, and hotness among the pre-mature, mature, pre-ripening, and ripening stages of four distinct chili cultivars. Four different cultivars of chilis at four different maturity stages were collected and analyzed for their antioxidant and bioactive profiles. The findings of the research revealed that all chili varieties exhibited a notable range of vitamin C concentration, ranging from 1.67 to 8.45 mg/g FW during the maturity stages. The values of TPC, TFC, total carotenoids, and chlorophyll a and b ranged from 16.68 to 46.76 mg GAE/g, 2.80-8.53 mg QE/g, 4.31-85.79 µg/g DW, 2.83-15.54 and 0.74-5.66 µg/g DW on a dry weight basis, respectively. The antioxidant activity was assessed using the FRAP and the DPPH scavenging assay and the values ranged from 142.62 to 311.03 mM Fe (II) Equivalent/100g DW and 216.36-329.52 µM Trolox Equivalent/g DW, respectively. The content of vitamin C, TPC, total carotenoids, and chlorophyll b was increased with the stages of development. The hotness of chili also increased with the development stages. However, the antioxidant activity fluctuated during the development stages of chili. Furthermore, the study incorporated the evaluation of physical parameters, such as height, weight, and color attributes concerning chilies. The Naga variety of chili demonstrated the highest level of efficacy when compared to other varieties. The nutritional and physicochemical information of the different cultivars of chili in this study might be useful to the breeders, spice processors, and consumers for desired size, taste, and hotness with health-promoting bioactive compounds, eventually for determining the harvest time.

RESUMO

With the aim of finding the plant-derived allosteric inhibitors of caspase-3/-7, we conducted computational investigations of bioactive compounds present in various berry fruits. In a molecular docking study, perulactone demonstrated excellent binding affinity scores of -12.1 kcal/mol and -9.1 kcal/mol for caspase 7 and 3, respectively, whereas FDA-approved allosteric inhibitors (DICA and FICA) were found to show lower docking scores (-5.6 and -6.1 kcal/mol) against caspase 7 while (-5.0 and -5.1 kcal/mol) for caspase 3, respectively. MD simulations were used to validate the binding stability of perulactone in the active sites of caspase-7/-3, and the results showed outstanding stability with lower ligand RMSDs of 1.270-3.088 Å and 2.426-9.850 Å against the targeted receptor. Furthermore, we performed MMGBSA free binding energy, where the perulactone values of ΔG Bind were determined to be -63.98 kcal/mol and -66.32 kcal/mol for both receptors (3IBF and 1NME), which are significantly better than the -45.16 kcal/mol and -39.51 kcal/mol for DICA as well as -26.37 kcal/mol and -15.50 kcal/mol for FICA, respectively. The drug resemblance of perulactone was effectively evaluated by ADMET. Thus, our findings indicated that perulactone could be an orally administered therapeutic candidate for regulating apoptosis in a variety of disorders. However, there may be an urgent need to study using in vitro and in vivo experiments.

RESUMO

Dhaka is one of the world's densely populated cities and faces significant public health challenges including high burden of diarrhoeal diseases. Climate change is intensifying existing environmental problems including urban heat island effect and poor water quality. While numerous epidemiological studies have linked meteorological factors to diarrhoeal diseases in Bangladesh, assessment of the impacts of future climate change on diarrhoeal diseases is scarce. We provide the assessment of climate change impacts on diarrhoeal disease in Dhaka and project future health risks under climate change scenarios. About 3 million acute diarrhoea cases presenting to the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research Bangladesh (icddr,b) during 1981-2010 were linked to daily temperature, rainfall and humidity and association investigated using time series adapted negative binomial regression models employing constrained distributed lag linear models. The findings were applied to climate projections to estimate future risks of diarrhoea under various global warming scenarios. There was a significantly raised risk of diarrhoea hospitalisation in all ages with daily mean temperature (RR: 3.4, 95% CI: 3.0-3.7) after controlling for the confounding effects of heavy rainfall, humidity, autocorrelations, day of the week effect, long-term time, and seasonal trends. Using the incidence rate ratio (IRR) of 1.034, temperature increases based on the global warming targets of 1.5-2°C could result in an increase of diarrhoea hospitalisations by 4.5-7.4% in all age groups by the 2100s. These effects were more pronounced among <5 children where the predicted temperature increases could raise diarrhoea hospitalisation by 5.7% - 9.4%. Diarrhoea hospitalisation will increase significantly in Dhaka even if the global warming targets adopted by the Paris Agreement is reached. This underscores the importance of preparing the city for management and prevention of diarrhoeal diseases.

RESUMO

AIMS: To assess the reproducibility of interpreting hypoattenuated thickening (HAT) and peridevice leak (PDL) using cardiac computed tomography (CT) imaging following Watchman FLX left atrial appendage closure (LAAC). METHODS AND RESULTS: In this multicenter retrospective reproducibility study, 100 anonymized post-LAAC cardiac CT scans were evaluated within the same cardiac phase by an experienced and a novice rater blinded to prior evaluations. All scans were evaluated twice by each rater, assessing overall HAT and PDL categories as well as specific associated findings based on suggested algorithms for post-LAAC interpretation. Inter- and intra-rater agreement and reliability were evaluated using absolute agreement, Cohen's kappa and Kendall's tau for categorical variables, and mean difference, Bland-Altman plots, limits of agreement and intraclass correlation coefficients (ICC) for continuous variables.Within overall categories of both HAT and PDL, substantial agreement (kappa >0.61) and reliability (Kendall's tau-b  > 0.75) were observed. Specifically, identifying high-grade HAT (kappa >0.78) and distal patency (kappa >0.85) displayed the highest agreement within HAT and PDL interpretation. Meanwhile, measuring the height of the proximal screw hub cove represented the least reliable HAT assessment among both inter- and intra-rater comparisons (ICC<0.75), while suspected leak mechanism represented the least reproducible PDL measure. CONCLUSION: Despite only minimal training of one rater, overall high levels of inter- and intra-rater agreement and reliability were observed across the chosen algorithms for interpretation of HAT and PDL following Watchman FLX LAAC. Prognostic implications of the included variables are to be explored in future trials and registries.

RESUMO

While numerous studies have assessed the association between temperature and diarrhoea in various locations, evidence of relationship between heat wave and diarrhoea is scarce. We defined elevated daily mean and maximum temperature over the 95th and 99th percentiles lasting for at least one day between March to October 1981-2010 as TAV95 and TAV99 and D95 and D99 heat wave, respectively. We investigated the association between heat wave and daily counts of hospitalisations for all-cause diarrhoea in Dhaka, Bangladesh using time series regression analysis employing constrained distributed lag-linear models. Effects were assessed for all ages and children aged under 5 years of age. Diarrhoea hospitalisation increased by 6.7% (95% CI: 4.6%- 8.9%), 8.3% (3.7-13.1), 7.0 (4.8-9.3) and 7.4 (3.1-11.9) in all ages on a TAV95, TAV99, D95 and D99 heat wave day, respectively. These effects were more pronounced for under-5 children with an increase of 13.9% (95% CI: 8.3-19.9), 24.2% (11.3-38.7), 17.0 (11.0-23.5) and 19.5 (7.7-32.6) in diarrhoea hospitalisations on a TAV95, TAV99, D95 and D99 heat wave day, respectively. At lags of 3 days, we noticed a negative association indicating a 'harvesting' effect. Our findings suggest that heat wave was a significant risk factor for diarrhoea hospitalisation in Dhaka. Further research is needed to elucidate the causal pathways and identify the preventive measures necessary to mitigate the impacts of heat waves on diarrhoea. Given that no heat wave definitions exist for Dhaka, these results may help to define heat waves for Dhaka and trigger public health interventions including heat alerts to prevent heat-related morbidity in Dhaka, Bangladesh.

RESUMO

It remains unclear whether and how maternal exposure to biomass fuel influences infant anthropometry or body proportionality at birth, which are linked to their survival, physical growth, and neurodevelopment. Therefore, this study seeks to explore the association between household-level exposure to biomass cooking fuels and infant size and body proportionality at birth among women in rural Bangladesh. A total of 909 women were derived from the Pregnancy Weight Gain study, which was conducted in Matlab, a rural area of Bangladesh. Infant's weight (g), length (cm), head circumference (cm), small for gestational age (SGAW), short for gestational age (SGAL), low head circumference for gestational age (SGAHC), ponderal index, and cephalization index at birth were the outcomes studied. Of the women, 721 (79.3%) were dependent on biomass fuel. Compared to infants born to mothers who used gas for cooking, those born to biomass users had lower weight (ß - 94.3, CI - 155.9, - 32.6), length (ß - 0.36, 95% CI - 0.68, - 0.04), head circumference (ß - 0.24, CI - 0.47, - 0.02) and higher cephalization index (ß 0.03, CI 0.01, 0.05) at birth. Maternal biomass exposure is more likely to lead to symmetric SGA, although there is evidence for some brain-sparing effects.

RESUMO

The Ti-5Al-5V-5Mo-3Cr (Ti-5553) alloy is a relatively novel difficult-to-cut material with limited machinability and tool life analysis available in the literature, and hence requires further investigation. This study focuses on the machining and tribological performance of Ti-5553 under high-speed finish turning (150 m/min, 175 m/min, and 200 m/min) via novel mono/bi-layered PVD-coated WC tools. A base AlTiN coating is used as the reference monolayer coating, with AlCrN, diamond-like ta-C, and TiAlSiN coatings each deposited on top of a base AlTiN coating, totaling four separate coated tools (one monolayer and three bi-layer). Tool life, cutting forces, workpiece surface quality, and tribological chip analysis are among the subjects of investigation in this study. Overall, the AlTiN/AlCrN coated tool outperformed all the other combinations: an improvement of ~19% in terms of tool life in reference to the base AlTiN coating when averaging across the three speeds; lowest surface roughness values: ~0.30, 0.33, and 0.64 µm; as well as the lowest chip back surface roughness values: ~0.80, 0.68, and 0.81 µm at 150, 175, and 200 m/min, respectively. These results indicate that the AlTiN/AlCrN coating is an excellent candidate for industrial applications involving high-speed machining of Ti-5553.

RESUMO

INTRODUCTION: The ideal antiplatelet therapy to maintain graft patency after coronary artery bypass graft surgery (CABG) remains controversial. This review of randomized controlled trials (RCTs) aims to compare aspirin monotherapy, ticagrelor monotherapy, dual antiplatelet therapy (DAPT) with aspirin and ticagrelor (Asp+Tica) or with aspirin and clopidogrel (Asp+Clopi) to evaluate differences in post-CABG saphenous vein graft (SVG) occlusion, internal mammary artery (IMA) occlusion, myocardial infarction (MI), bleeding, and all-cause mortality (ACM) rates. EVIDENCE ACQUISITION: The literature review was conducted on several electronic databases, including Medline, Embase, and Cochrane Central, from inception to August 10, 2022. Data was extracted using a predefined proforma. A Bayesian random-effects model was used for calculating point effect estimates (odds ratio and standard deviation). Quality assessment was done using the Cochrane RoB-2 tool. EVIDENCE SYNTHESIS: Ten RCTs comprising 2139 patients taking anti-platelets post-CABG were included. For preventing SVG occlusion, Asp+Tica showed the lowest mean AR of 0.144±0.068. Asp+Tica also showed a trend toward lesser postoperative MI risk and lower ACM rates, with a mean AR of 0.040±0.053 and 0.018±0.029, respectively. For maintaining IMA graft patency, Asp+Clopi showed the lowest mean AR of 0.092±0.053. Ticagrelor had the lowest mean AR of 0.049±0.075, with Asp+Tica showing a similar mean AR of 0.049±0.045 for postoperative major bleeding risk. CONCLUSIONS: Our analysis demonstrates that Asp+Tica can be the ideal therapy for patients undergoing CABG using SVG as it decreases the risk of post-CABG SVG occlusion and is not associated with a significantly higher risk for major bleeding.

RESUMO

The study aimed to evaluate trace metals in the groundwater of Chattogram City located on the southeastern coast of Bangladesh and assess their potential health risks. Given the city's unique characteristics as both a coastal and industrial hub in Bangladesh, a knowledge gap persists particularly in the assessment of trace metals. A random sampling technique was applied to collect one hundred and seventeen groundwater samples from different wards of the city to analyze some trace metals (Cr, Cd, Fe, Cu, Mn, Pb, and Zn) and the quality of the collected water samples was evaluated using different indices, such as Heavy Metal Evaluation Index (HEI), Groundwater Quality Index (GWQI), Heavy Metal Pollution Index (HPI), and Degree of Contamination (Cd). The average concentration of all the studied metals except Fe, Mn, and Cd satisfied the Bangladesh drinking water standards. The Fe, Mn, and Cd content were observed higher in shallow wells (depth 10-150 ft) followed by intermediate (151-300 ft) and deep wells (>300 ft). However, the Cr, Cu, and Zn content did not significantly change with aquifer depth. The spatial distribution map showed that the highest values of Mn and Cu were observed in the west-northern region of the city. Metal As was only found in shallow and intermediate aquifers. The HEI suggested that about 9 % of samples fall into the higher degree of pollution category similar to the GWQI, while 37 % and 42 % of samples exhibited a higher degree of pollution in the case of HPI and Cd, respectively. The positive correlations and loadings found in the statistical analysis indicated that Fe, Mn, and Cu originated from the same sources. A variety of industrial activities might be ascribed to this type of pollution. However, an average Hazard Quotient (HQ) through ingestion was found to be greater than 1 for Cd, and the Carcinogenic Risk (CR) values for children were identified as two-fold higher than that of adults. Raising social awareness, avoiding the usage of groundwater without proper treatment, and strict regulations and monitoring by the concerned authority are recommended in the study.

RESUMO

Type 2 diabetes mellitus (T2DM) and pre-diabetes (pre-DM) are significant health concerns in Pakistan. This systematic review and meta-analysis estimate the prevalence of T2DM and pre-DM, assessing regional, gender, and urban-rural differences. We searched PubMed, Scopus, Cochrane, and PakMediNet databases, identifying 3478 articles. After screening, 17 studies from 1995 to 2018 were included. The pooled prevalence of T2DM and pre-DM in Pakistan was found to be 10.0 % and 11.0 %, respectively. This equates to approximately 24 million individuals with T2DM and 26 million with pre-DM, totaling 50 million affected. Rural areas showed higher T2DM prevalence post-2000, with an odds ratio (OR) of 1.25 (95 % CI: 0.73 to 2.14). Gender analysis revealed a slightly higher, though statistically insignificant, prevalence of T2DM in females and a significantly higher prevalence of pre-DM in males (OR: 0.79, 95 % CI: 0.63 to 0.98). Regionally, Punjab had the highest T2DM prevalence (16 %), followed by Baluchistan (15 %), Sindh (14 %), and Khyber Pakhtunkhwa (KPK) (11 %). There is a substantial burden of T2DM and pre-DM in Pakistan, with significant regional and gender differences. Targeted interventions and resource allocation are needed to address the rising prevalence of diabetes, focusing on early detection and lifestyle modifications.

RESUMO

Background: Use of different social media platforms has increased radically over the past decade, emerging as an important part of adolescents and young people's everyday life. This might exert potential adverse effects on sleep quality and daytime performance of young adults. Aim of Study: To assess the relation between use of social media platforms and sleep quality among public secondary school students. Methods: A cross-sectional study was conducted on 961 students in Aseer region, Saudi Arabia. Students were asked to fill in a structured interview questionnaire covering personal data, pattern of social media use, sleep quality using The Pittsburgh Sleep Quality Index (PSQI) and their mental health status using the depression, anxiety and stress scale (DASS-21). Results: Students' ages ranged from 15 to 20 years with a mean age of 16.7 ± 2.1 years old. A total of 570 (59.3%) students were females. Tiktok (80%), Snapchat (77.9%), Instagram (63.8%) and YouTube (58.8%) were the most reported platforms used. Regarding their sleep quality, 34.7% of students were poor sleepers. TikTok use (OR 1.33, 95% CI 1.01-1.77), hours spent on social media (OR 1.26, 95% CI 1.16-1.37) and having moderate to severe depressive symptoms (OR 1.69, 95% CI 1.19-2.40) were significant independent predictors of poor sleep among the studied sample. Conclusion: The present study emphasized the association between prolonged use of social media and poor sleep quality among Saudi adolescents. Awareness and behavioral change strategies and activities concerning the drawbacks of poor sleep and proper use of social media are urgently called for to control mental and physical health consequences of poor sleep and social media addiction.

RESUMO

INTRODUCTION: Treatment in the intensive care unit (ICU) generates complex data where machine learning (ML) modelling could be beneficial. Using routine hospital data, we evaluated the ability of multiple ML models to predict inpatient mortality in a paediatric population in a low/middle-income country. METHOD: We retrospectively analysed hospital record data from 0-59 months old children admitted to the ICU of Dhaka hospital of International Centre for Diarrhoeal Disease Research, Bangladesh. Five commonly used ML models- logistic regression, least absolute shrinkage and selection operator, elastic net, gradient boosting trees (GBT) and random forest (RF), were evaluated using the area under the receiver operating characteristic curve (AUROC). Top predictors were selected using RF mean decrease Gini scores as the feature importance values. RESULTS: Data from 5669 children was used and was reduced to 3505 patients (10% death, 90% survived) following missing data removal. The mean patient age was 10.8 months (SD=10.5). The top performing models based on the validation performance measured by mean 10-fold cross-validation AUROC on the training data set were RF and GBT. Hyperparameters were selected using cross-validation and then tested in an unseen test set. The models developed used demographic, anthropometric, clinical, biochemistry and haematological data for mortality prediction. We found RF consistently outperformed GBT and predicted the mortality with AUROC of ≥0.87 in the test set when three or more laboratory measurements were included. However, after the inclusion of a fourth laboratory measurement, very minor predictive gains (AUROC 0.87 vs 0.88) resulted. The best predictors were the biochemistry and haematological measurements, with the top predictors being total CO2, potassium, creatinine and total calcium. CONCLUSIONS: Mortality in children admitted to ICU can be predicted with high accuracy using RF ML models in a real-life data set using multiple laboratory measurements with the most important features primarily coming from patient biochemistry and haematology.

RESUMO

BACKGROUND: A randomized controlled trial in Bangladeshi children aged 12 to 18 months with moderate acute malnutrition found that dietary supplementation with the microbiota-directed complementary food (MDCF-2) significantly improved weight gain and repaired gut microbiota compared to the ready-to-use supplementary food. However, the MDCF-2 formulation was made daily from locally available ingredients and the need for a packaged, nutritionally compliant, and organoleptically acceptable MDCF-2 prototype was essential for future large-scale clinical studies. OBJECTIVE: The study aimed to develop and assess the acceptability of 3 alternative foil-packaged formulations of MDCF-2 in comparison to current MDCF-2. METHODS: Of the 3 packaged formulations, the Jumpstart version was provided in 2 sachets, the other 2 formulations were provided in a retort-stable foil pouch extended by sterilization, and microbiological growth was monitored over 10 months. The acceptability study included 40 children aged 8 to 12 months living in an urban slum in Dhaka, and the organoleptic properties were assessed using a 7-point hedonic scale. RESULTS: In the 100 g distributed over the 2 sessions, children consumed 82.5 ± 7.84 g (mean ± SD) of kitchen-prepared MDCF-2, 85.4 ± 7.15 g of the "Jumpstart" MDCF-2 formulation, 85.4 ± 8.70 g of the MDCF-2 with green banana powder, and 86.2 ± 4.26 g of the MDCF-2 with sweet potato formulation. The "Jumpstart" MDCF-2 and MDCF-2 with sweet potato achieved the highest overall acceptability scores on the hedonic scale; although none of the shelf-stable formulations were significantly different from the kitchen-prepared MDCF-2. CONCLUSIONS: Packaged, shelf-stable prototypes of MDCF-2 exhibited comparable acceptability among Bangladeshi children aged 8 to 12 months to the original freshly prepared formulation.


Plain language titleDevelopment and Acceptability of Shelf-Stable Microbiota-Directed Complementary FoodsPlain language summaryCountries around the world are making progress in fighting malnutrition, but it may be challenging to achieve the global nutrition targets for undernourished children by 2025 at the current rate. To address this problem, we need special types of food that can help children grow, develop properly, and sustain their growth. Children with moderate acute malnutrition have imbalanced gut bacteria. By providing them with the right nutrition, we can restore the healthy bacteria in their gut using a special food called microbiota-directed complementary food (MDCF). Currently, this food is made daily in the icddr, b established field kitchen, which follows standard production measures to control the quality of MDCF preparation, but we need to create stable prototypes that can be stored and used in different settings. This study was designed to develop shelf-stable new formulations in industrial settings and check their acceptability among children with moderate acute malnutrition. The shelf life of the food was extended using a sterilization method, and its microbiological safety was monitored for a year. The actual consumption and acceptability of these foods were evaluated and all these formulations were acceptable by the children and their mother. The children consumed all 4 food formulations in substantial quantities, with consumption rates exceeding 80% for each formulation. This study showed positive results in Bangladesh, but more research is needed to see if these formulations work well in other geographies and over longer periods.

RESUMO

Diabetes mellitus (DM) is a chronic metabolic disorder characterized by persistent hyperglycemia. It involves disturbances in carbohydrate, fat, and protein metabolism due to defects in insulin secretion, insulin action, or both. Novel therapeutic approaches are continuously being explored to enhance metabolic control and prevent complications associated with the disease. This study investigates the therapeutic potential of kaempherol-3-rhamnoside, a flavonoid, in managing diabetes by modulating the AMP-activated protein kinase (AMPK) pathway and improving metabolic enzyme activities in streptozotocin (STZ) -induced diabetic mice. Diabetic mice were treated with varying doses of kaempherol-3-rhamnoside and/or insulin over a 28-day period. Glycolytic and gluconeogenesis enzyme activities in the liver, fasting blood glucose levels, serum insulin levels, lipid profiles and oxidative stress markers were assessed. Treatment with kaempherol-3-rhamnoside significantly improved glycolytic enzyme activities, reduced fasting blood glucose, and enhanced insulin levels compared to diabetic controls. The compound also normalized lipid profiles and reduced oxidative stress in the liver, suggesting its potential in reversing diabetic dyslipidemia and oxidative damage. Furthermore, kaempherol-3-rhamnoside activated the AMPK pathway, indicating a mechanism through which it could exert its effects. Kaempherol-3-rhamnoside exhibits promising antidiabetic properties, potentially through AMPK pathway activation and metabolic enzyme modulation. These findings support its potential use as an adjunct therapy for diabetes management. Further clinical studies are warranted to validate these results in human subjects.

RESUMO

BACKGROUND: Short-term antithrombotic therapy is recommended after left atrial appendage occlusion (LAAO) to reduce the risk of device-related thrombosis. However, patients referred for LAAO have excess bleeding risk. Yet, short-term bleeding events post-LAAO are not well characterized. OBJECTIVES: We aimed to evaluate the incidence of early bleeding post-LAAO and its association with long-term mortality risk. We also sought to identify predictors of early bleeding. METHODS: Patients who underwent LAAO at Mayo Clinic between 2018 and 2023 were included. Early bleeding was defined as bleeding that occurred within 3 months of discharge. A multivariable Cox proportional hazards model was used to assess the association between early bleeding and death and to estimate the hazard ratio. Multivariable regression analysis was used to identify predictors of early bleeding. RESULTS: Of the 592 patients included, 389 (66%) were male, and the mean age was 75.6 years. Eighty-three patients (14.0%) experienced early bleeding, with the majority having minimal (63.4%) or minor (17.3%) bleeding. At a median follow-up of 14.4 months (interquartile range 4.2-27.9 months), early bleeding after LAAO was associated with an increased risk of all-cause mortality (adjusted hazard ratio 2.07; 95% confidence interval 1.15-3.75; P = .02). A history of intracranial bleeding, nonparoxysmal atrial fibrillation, CHA2DS2-VASc score, and early device-related thrombosis were independent predictors of early bleeding. Antithrombotic therapy at discharge was not associated with early nonprocedural bleeding. CONCLUSION: One in 7 patients experience a nonprocedural bleeding event within 90 days of LAAO. Early bleeding after LAAO is associated with a higher all-cause mortality risk during mid-term follow-up. Further studies are needed to optimize the management of patients undergoing LAAO.

RESUMO

Pomelo (Citrus maxima), the largest citrus fruit, provides a variety of nutrients that have several health benefits, including antioxidant and antidiabetic functions. Antioxidants help combat oxidative stress by neutralizing reactive oxygen species (ROS) and reducing cellular damage. On the other hand, antidiabetic properties involve mechanisms such as enhancing insulin secretion, improving insulin sensitivity, inhibiting carbohydrate digestion and absorption, and regulating glucose metabolism. However, there is a lack of data on the comparative analysis of the physicochemical composition, bioactive properties, and antidiabetic effects of pomelo fruits grown in Bangladesh. To address this issue, the most common and popular high-yielding five cultivars of pomelo fruits grown in Bangladesh including LOCAL, BARI-2 (BARI: Bangladesh Agricultural Research Institute, Batabi Lebu-2), BARI-3, BARI-4, and BARI-6 were evaluated concerning proximate, minerals, and physicochemical properties with their antidiabetic and antioxidant properties. Research has revealed that all pomelo varieties contained a significant amount of proximate compositions and major minerals (Ca, Mg, K, Na, and Fe). The highest juice yield (75.37 ± 0.33 %), vitamin C content (79.56 ± 2.26 mg/100 mL of fresh juice), and carotenoid content (919.33 ± 0.62 µM ß-Carotene Equivalent/g DM) were found in BARI-3 pomelo fruit and adhered to the sequence (p < 0.05): BARI-3 > LOCAL > BARI-4 > BARI-6 > BARI-2; BARI-3 > LOCAL > BARI-2 > BARI-4 > BARI-6, and BARI-3 > BARI-2 > BARI-6 > LOCAL > BARI-4, respectively. The anthocyanin content and inhibitory activity of α-glucosidase were found to be at their peak in the BARI-2 pomelo variety and the values were 50.65 ± 2.27 µg cyanidin 3-glucoside equivalents/100 g DM and 85.57 ± 0.00 µM acarbose equivalents/g DM, respectively. BARI-3 pomelo variety showed highest DPPH antioxidant capacity (170.47 ± 0.01 µM Trolox equivalents/g DM), while the BARI-6 pomelo variety exhibited the highest total phenolic content (6712.30 ± 1.84 µg gallic acid equivalents/g DM), and ferric-reducing antioxidant power activity (183.16 ± 0.01 µM Fe(II) equivalents/g DM). Therefore, this study explores the nutritional value and bioactivity of five popular pomelo varieties in Bangladesh, offering valuable insights for utilizing high-value citrus resources and understanding their health-promoting functions.

RESUMO

Parvimonas micra bacteremia is rarely encountered in clinical practice. When it is, patients usually have underlying periodontal disease or colorectal carcinoma. To the best of our knowledge, this is the first case of P. micra bacteremia in a patient without the predisposing risk factors listed above. We postulate that this occurred because of translocation across an interrupted gut-blood barrier in the setting of an acute upper gastrointestinal bleed. We present this case to highlight the importance of identifying and treating P. micra bacteremia because it can prevent commonly encountered sequelae of untreated bacteremia and improve outcomes.

RESUMO

Protein-based ultrafine fibrous scaffolds can mimic the native extracellular matrices (ECMs) with regard to the morphology and chemical composition but suffer from poor mechanical and wet stability. As a result, cells cannot get a true three-dimensional (3D) environment as they find in native ECMs. In this study, an epoxide, ethylene glycol diglycidylether (EGDE), with high reactivity to active hydrogen is introduced to gelatin solution, serving as an effective cross-linker. The gelatin/EGDE 3D-ultrafine (∼500 nm in diameter) fibrous composite scaffolds are made by an ultralow-concentration phase separation technique (ULCPS). The effects of the polymer content and modification conditions on the morphology and wet stability of the constructs are investigated. It is revealed that ultrafine fibers with 3D random orientation could be formed at low concentrations (0.01, 0.05, and 0.1 wt %, respectively). The wet stability of the constructs could be effectively improved by introducing EGDE into the gelatin system. The shrinkage is reduced to merely 2.14% after the modification at 120 °C for 2 h and could be maintained for up to 3 days. In order to improve the compression properties, the same technique is utilized with the presence of a poly(lactic acid) (PLA) spacer fabric to produce a bicomponent scaffold. The mechanical property and cell viability of the bicomponent scaffolds are investigated, and it is found that cells could enter deep inside and orient themselves randomly at the central area of the bicomponent scaffold. The modification and design approach presented in this study has the potential to provide various protein-based ultrafine fibrous biomaterials for a variety of biomedical applications.

RESUMO

Recent advancement in surgical treatment of haemorrhoidal disease is not accessible by low socio-economic group of patient in a peripheral hospital of an underdeveloped country, where we aimed to evaluate the outcome of conventional surgeries. This descriptive, prospective, observational study was performed from diagnosis of haemorrhoidal disease to surgical intervention and followed up 12 months post operatively. Clinico-pathological data and outcome in the form of complications and recurrence within follow-up period was studied. Total 64 adult patients with mean age 38.6 years and male female ratio 1.7:1 were included in this study. Mean duration of symptoms was 13 months, reflects late presentation. Two (2) piles mass was seen most frequent in 36(56.3%) cases and most of the patients i.e. 44(68.8%) had haemorrhoids only on primary sites (3, 7 and 11 o'clock) of anal canal, but 18(28.1%) had mixed primary and secondary position of haemorrhoids. Similarly among those who had more than one haemorrhoid, grade 4 was commonest 35(53.1%) followed by only grade 3 in 15(23.4%) cases but mixed grade 3 and 4 was seen in 10(15.6%) patient. Complication less recovery was seen in 56(87.5%) cases, where delayed wound healing and pain was reported in 2(3.6%) patient each, followed by 1(1.6%) each reported urinary retention, anal sepsis, primary bleeding and reactionary bleeding. Mean hospital stay was 4 days. Conventional surgeries are equally efficacious and cost effective option for management of operable haemorrhoidal disease at any setup.
