Authors: Hossain Sahadat , Alam Md Zakiul 
Published: January 2024

Abstract
Background
Bangladesh's old population is growing faster than the rest of the world and is anticipated to continue in the coming years. The country's growing older adult is challenging Bangladesh's existing health system, and it must be reformed to ensure geriatric care. The main objective of this study is to measure the existing gap in perceived and expected healthcare needs among older adults and propose a measure to eliminate the gap.
Methods
Using a cross-sectional research design, we collected data from 500 respondents in Narsingdi and Narayanganj districts. The gap between the older adults' perceived and expected healthcare needs was assessed using a structured questionnaire with 28 items (using the Kano Model) that could be answered positively and negatively. Descriptive statistics, T-tests, and multiple linear regression analyses were carried out.
Results
The findings showed where Bangladesh's healthcare sector, particularly older adult care services, comes close to matching their expectations and areas where it falls far short. The Kano model showed that 12 of 28 geriatric health service qualities were classified as Must-Be quality and eight as attractive or delighters. Type of residence (β=-0.264, p < 0.001), quality of life (β = 0.227, p < 0.001), marital status (β=-0.104, p = 0.047), and educational status (β=-0.124, p = 0.015) was significantly associated with of older population health care needs and expectation.
Conclusion
This study gives healthcare practitioners a detailed understanding of their service quality from the perspective of patient satisfaction in Bangladesh. Reforming and modifying the country's existing healthcare structure services for older adults while keeping these attributes in mind will likely result in a safe and healthy environment for them.

Published: January 2024

Abstract
This study aimed to develop a functional additive to reduce the release of formaldehyde in wood-based panel products. Sodium chlorite microcapsules, capable of releasing chlorine dioxide, were prepared using sodium alginate/ethyl cellulose as shell materials and sodium chlorite as the core material. The preparation process employed the ionic gel-solvent evaporation method. Influencing factors, such as the mass ratio of sodium chlorite to ethyl cellulose, the emulsifier content, and the mass fraction of sodium alginate, were systematically varied to optimize the microcapsule preparation process. The evaluation index of coverage rate was utilized for optimization. The optimum preparation process was determined as follows: a mass ratio of 2.44:1 for sodium chlorite to ethyl cellulose, an emulsifier dosage of 1.15g, a mass fraction of sodium alginate at 12.52%, resulting in a coverage rate of 63.51%. The formation mechanism was analyzed using various analytical instruments. Fourier transform infrared spectroscopy (FTIR) revealed characteristic absorption peaks of sodium chlorite, sodium alginate, and ethyl cellulose in the microcapsule spectrum. Thermogravimetric analysis (TG-TGA) indicated that the residual content of microcapsules surpassed that of the shell material, ethyl cellulose, suggesting higher thermal stability. Additionally, the weight loss rate of microcapsules at 120℃ was lower, meeting the requirements for the hot-pressing process of wood-based panels. Observation under an optical microscope (OM) and scanning electron microscope (SEM) confirmed microcapsules with an average particle size of 58.71 ± 9.35µm, displaying uniform distribution and distinct surface folds.

Abstract
Structural analyses of glass fiber reinforced epoxy polymer (GFRP) composite dispersed with rutile (TiO2) nano-particles using compressions molding was studied to reveal the effects of filler addition. Ball milling performed for nano-particles and reduce the particle size from 3 mm to 67.64 nm to enhance blending of dispersions in the resin. The nano-particle added to resin at weight percentage of 0%, 5%, 10% and 15% prior to fabrication using ultrasonic liquid processor. Flexural strength, tensile strength, hardness and toughness were conducted to study the mechanical behavior of the composite. Addition of filler showed improvement in the mechanical properties of GFRP dispersion strengthened composite. 15 wt.% rutile particles have tensile strengths of 228 MPa, tensile moduli of 4123 MPa, flexural strengths of 317 MPa, and flexural moduli of 10010 MPa, respectively. These values are 0.588%, 16.8%, 82.22%, and 96.5% greater than the values of 0 wt.% rutile inclusion. In comparison to the pristine specimen, the shore "D" hardness of materials with 10 wt.% TiO2 is 8.43% higher, while that of materials with 15 wt.% TiO2 is 3.6% higher. The impact strength of the composite sample with 5 wt.% TiO2 is 72% greater than that of the pure sample. Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray Spectroscopy (EDS) and X-ray diffraction (XRD) were carried to analyses morphological behavior, percentages of different elemental distributions and crystalline size and structure of nano-particle in the composite. FESEM was used to reveal the pullout of fiber, damaged interfaces, filler dispersion, and voids in specimens. Hence Ceramic filler inclusion reveals good characterization on GFRP composites.
Exploring the potent antimicrobial activity of manuka honey as against clinically isolated multi-drug resistant and ceftriaxone-resistant Salmonella Typhi in septicemia patients: a promising therapeutic option
Authors: Bashir Iqra , Rasool Muhammad Hidayat , Shafique Muhammad , Jabeen Kokab , Qamar Muhammad Usman 
Published: January 2024

Abstract
Background: The rise of extensively drug-resistant SalmonellaTyphi is a significant concern in clinical settings, particularly among patients with septicemia. These pathogenic eggs were resistant to first and second-line drugs, including ceftriaxone, except azithromycin. Mauka honey serves as a viable alternative treatment choice in combating these diseases. Hence, our main objective is to ascertain the antimicrobial efficacy of manuka honey against multidrug-resistant (MDR) and extensively drug-resistant (XDR) clinical strains of S. Typhi.
Methods: A combined total of 50 MDR and 50 XDR S. Typhi clinical isolates were obtained from patients with septicemia. Following the Bactec blood culture system, the isolates were sub-cultured on blood and MacConkey agar and their biochemical confirmation and susceptibility to different antibiotics was done using the Vitek 2 compact system. The PCR technique was used to amplify the antibiotic-resistance genes. The antibacterial activity of Manuka honey was assessed using the agar well diffusion assay and micro broth dilution assay.
Results: All 100 isolates were verified to be S. Typh. Out of the total, 50% of the S. Typhi bacteria were MDR and 50% were XDR. These bacteria were only susceptible to azithromycin and carbapenems. These strains exhibited amplification of H58, gyrA, andgyrB genes, blaCTX-M-15 and blaTEM genes. The zone of inhibition for MDR and XDR-S. typhi was shown to range from 15-24mm and 15-23mm, respectively, while using 100% manuka honey. The MDR-S. Typhi 18/50 (36%) strain and XDR-S. Typhi 14/50 (28%) strain was inhibited at a concentration of 3.125 v/v%.
Conclusion: Manuka honey could be an alternative option against MDR and XDR S. Typhi.

Published: January 2024

Abstract
The Kirchhoff model is derived from the vibration problem of stretchable strings. In this paper, we focus on the longtime dynamics of higher-order (m1, m2) - coupled Kirchhoff system with higher-order rotational inertia and nonlocal Damping. We first obtained the state of the model's solutions in different spaces through prior estimation, After obtaining the state of the solutions, we immediately proved the existence and uniqueness of their solutions in different spaces through the Faedo-Galerkin method. Subsequently, we proved their family of global attractors using the compactness theorem. At the end of the paper, we reflected on the subsequent research of the model, which pointed out relevant directions for further research on the model. In this way, we systematically studied the longtime dynamic of higher-order $(m_1,m_2)-$coupled Kirchhoff model with higher-order Rotational Inertia, thus enriching the related conclusions of higher-order coupled Kirchhoff models and laying a theoretical foundation for future practical applications.

Authors: Islam Mst. Tania , Islam Mohammad , Zakaria Md. 
Published: January 2024

Abstract

Bangladesh has a highly vulnerable 710 km long low-lying coastline with over 29% of the country’s population residing in coastal districts. While existing literature examines inland rainfall patterns, analysis of rainfall variability along the coast is lacking. This study analyzes annual and seasonal rainfall trends across 17 coastal meteorological stations over 1948–2021. The non-parametric Mann-Kendall test and Sen’s Slope estimator are applied for trend detection and quantification. The findings reveal high interannual and spatial rainfall variability across stations, governed primarily by monsoonal dynamics. A seasonal analysis shows noticeable winter rainfall increases at Khulna and Satkhira at rates of 0.38 mm/year and 0.32 mm/year respectively. The critical monsoon months exhibit substantial incremental tendencies at Khepupara (11.77 mm/year), Hatiya (10.54 mm/year) and Kutubdia (15.50 mm/year). Additionally, post-monsoon rainfall rises significantly at Hatiya (5.25 mm/year). For annual totals, significant rising trends are observed at Khulna (7.69 mm/year), Khepupara (16.43 mm/year), Hatiya (21 mm/year) and Sandwip (12.45 mm/year). Across the seasonal and annual timescales, widespread non-significant increasing tendencies dominate over declining behaviors for most stations. This study provides key inputs for planning and policies to build climate resilience of vulnerable coastal populations.

Abstract
Purpose: To evaluate vascular changes in patients with diabetic macular ischemia (DMI) after systemic oxygen therapy using Optical coherence tomography angiography (OCTA).
Methods: This interventional before-after study included 26 eyes of 26 patients with DMI. Macular OCTA was performed before and after 1 hour of 100% oxygen therapy at a flow of 10 L/min by face mask. Changes in OCTA metrics were evaluated by paired t-test. Subgroup analyses were performed based on gender. Secondary outcomes included identifying parameters correlated with best-corrected visual acuity (BCVA) and factors associated with improvement in OCTA parameters.
Results: The patients included 15 males and 11 females aged 59.48 ± 9.67 years. Overall, no significant change was observed in retinal thickness, however, there was a significant decrease in females and a significant increase in males. (Both P<0.001)
Foveal avascular zone (FAZ) decreased significantly from 0.38 ± 0.14 to 0.34 ± 0.12 mm2. (P=0.035) Superficial capillary plexus vessel density (SCP VD) at fovea increased from 13.5 ± 6.37 to 14.98 ± 6.33 %. (P=0.059) Deep capillary plexus vessel density (DCP VD) at fovea increased from 24.61 ± 6.75 to 26.59 ± 6.16 %. (P=0.022) In males, BCVA correlated significantly with DCP parameters but none of SCP parameters. In females, BCVA showed significant correlation only with pre-O2 perifoveal inferior quadrant. Regression analysis failed to show any parameter predicting a favorable response.
Conclusion: This study showed beneficial effects of oxygen therapy for DMI by decreasing FAZ area and increasing DCP VD at fovea using OCTA.

Authors: Chen Hone , Zhu Yu ping , Yang Ju xiang , Wang Yi , Wang Hong chu , Song Gang 
Published: January 2024

Abstract
Objectives
The aim of this study is to examine the relationship between physical activity, smoking status and cognitive function, and to test the potential moderating role of physical activity.
Methods
This cross-sectional study used data on smoking status, cognitive function and physical activity from 1735 participants aged 60 years and older in NHANES from 2011 to 2014. Linear and logistic regression models were used to assess the association between smoking status and cognitive function. Mediation and moderation analyses were conducted to examine the role of physical activity in this association.
Results
Former smokers scored on average 2.090 points higher on the Digit Symbol Substitution Test (DSST) compared to never smokers (95% CI 0.755, 3.472; P < 0.05), while logistic regression showed that current smokers had an odds ratio (OR) of 0.629 for cognitive impairment compared to never smokers (95% CI 0.421, 0.941). No significant associations were observed between smoking status and CERAD and AFT. Moderation analysis showed that leisure-time physical activity significantly attenuated the effect of smoking on DSST scores in current smokers compared to never smokers (β = -2.014, P < 0.05).
Conclusion
There was a significant correlation between smoking status, physical activity and DSST scores.Although the mediating effect of leisure-time physical activity in the association between smoking status and cognitive function is not significant, it attenuates the decline in DSST scores in current smokers.

Published: January 2024

Abstract
Fermenting bacilli producing lactic acid including Bifidobacterium spp. is supposed to have low pathogenicity and no virulence for human. Probiotics is consisting of those fermenting bacilli and conformed to prevent and treat symptomatic gastrointestinal condition such as diarrhea. We use probiotics even in cancer patients, those who are immunocompromised. Some case report warns a rare risk of blood stream infection caused by probiotics. However, complete prohibition of probiotics use in cancer patients looks to abandon the benefits. We experienced a 75-year-old Japanese woman with malignant lymphoma treated with immune-chemotherapy consisting of rituximab and CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) regimen. The patient onset febrile neutropenia during chemotherapy and suffered from Bifidobacterium breve blood stream infection on day 8 after the 8th R-CHOP. She has usually eaten commercial yogurt every morning. This yogurt was produced from only Lactobacillus bulgaricus and Streptococcus thermophilus. It did not contain Bifidobacterium breve. The BSI infection in this case looked like derived from her food, however, it was not associated with her habitual foods. The patient was treated with meropenem for 8 days, and complete remission of BSI. We speculated inhabit fermenting bacilli can also be a source of blood stream infection, not associated to probiotics strain.

Published: January 2024

Abstract
Objective
Epilepsy is a chronic neurological disease that is highly susceptible to a variety of mental health problems due to its enormous biological, social, and psychological burdens. The purpose of this study was to determine the prevalence and to identify risk factors for common mental disorders (CMDs) in people with epilepsy (PWEs) in Goma, in the Democratic Republic of the Congo (DRC).
Methods
This is an analytical cross-sectional study conducted at the Neuropsychiatric Hospital Center in Goma (DRC) from March to April 2022 involving 302 PWEs. A questionnaire was administered to collect socio-demographic data, personal and family history, clinical features and management of epilepsy. CMDs were assessed using the self-report questionnaire (SRQ-20). Bivariate analysis was performed, followed by multivariate analysis, and variables with p < 0.05 in the final model were considered as risk factors associated with CMDs.
Results
The study included 302 PWEs, of which 56.9% were men, and the mean age was 28.4 ± 11.0 years. CMDs were present in 39.1% of the participants. The presence of CMDs was significantly associated with having five or more seizures in the month preceding the survey (adjusted odds ratio = 3.8; 95% CI: 1.7–8.3) and having medical co-morbidities (adjusted odds ratio = 3.1; 95% CI: 1.5–6.4).
Conclusion
The prevalence of CMDs in PWEs was high (39.1%), suggesting that this is a public health issue. Therefore, early detection and recognition of CMD symptoms should be a routine activity when managing PWEs.

Abstract
Objectives
Allo-Hematopoietic Stem Cell Transplantation (HSCT) offers a curative option for relapsed and refractory multiple myeloma in younger aged and fit patients with high-risk cytogenetic properties.
Material and Methods
This study retrospectively enrolled the medical data of 30 patients who had undergone allogeneic stem cell transplantation at the Gazi University Adult Stem Cell Transplant Unit between 2005 and 2020.
Results
Prior to allo-SCT, 6 (20.0%) patients were in complete remission; 8 (26.6%) had partial response; 14 (46.6%) had progressive disease, and 2 (6.6%) had stable disease. Overall survival (OS) at 1, 2, 3 and 5 years post-transplant were 45%, 36.3%, 31.7% and 22.7% respectively; transplant-related mortality (TRM) was 25.0% at 100 days. While the 5-year OS was 11.7% in the group with less than PR according to the pre-transplant disease status, it was found to be statistically significant as 45.8% in the group with CR or PR (p = 0.001). TRM was significantly higher in patients with less than PR compared has CR or PR at pre-transplantation (100% vs 43.7% p = 0.01). Like as these findings, PFS was shorter in patients with less than PR compared has CR or PR at pre-transplantation (6.2 vs 77.1 months, p = 0.01).
Conclusions
We found longer OS and PFS in patients with complete response before allo-SCT. This shows that the depth of response before allogeneic stem cell transplantation is effective on 100-day TRM in multiple myeloma patients. Allo-HSCT may be a therapeutic option in MM patients that relapse/ refractory after auto-SCT, particularly after achieving the least partial response.

Published: January 2024

Abstract

Multichannel spectral devices mounted on irrigation booms can be used to significantly enhance the quality assessment of forest seedlings in container nurseries. Contrary to traditional and time-consuming approaches such as laboratory analysis or destructive sampling, an active canopy optical sensor operates independently of ambient light conditions and does not necessitate spectral reference readings. Mobile irrigation systems in nurseries are ideal for incorporating plant scanners owing to their exceptional repeatability, ensuring consistently high-quality results. In our study, we rigorously tested a set of four ACS 435 Holland Scientific active crop canopy sensor along with the Vega Plus C21 laser sensor, all strategically positioned on a sprinkler boom above the nursery production field from May to September 2022. The seamless integration of these devices with the GeoSCOUT X Holland Scientific data acquisition unit formed the foundation of our system. The primary objective of this study was to develop a universal, lightweight, and mobile system that seamlessly integrates the scanner with the construction of the horizontal spray boom at a forest nursery. This innovative approach holds tremendous potential for advancing the assessment and management of forest seedlings, providing valuable insights and streamlining nursery operations.

Abstract
About 66% of firms claim that insider attacks are more likely to happen. The frequency of insider incidents has increased by 47% in the last two years. The goal of this work is to prevent dangerous employee behavior by using keyloggers and the MLmodel. Every keystroke that the user enters is recorded by the keylogging program, also known as keystroke logging. Keyloggers are used to stop improper use of the system. This enables us to collect all textual data, save it in a CSV file, and analyze it using an ML algorithm and the VirusTotal API.Many large companies use it to methodically monitor how their employees use computers, the internet, and email.We are utilizing the SVM algorithm and the VirusTotal API to improve overall efficiency and accuracy in identifying specific patterns and words to automate and offer the report for improved monitoring.
