Elucidating the Effects of Reaction Time on the Physicochemical Characterization of Valorized Synthesized Alumina

Aluminum waste-can management in Malaysia has recently become a serious environmental and public health issue, particularly in metropolitan areas. This has prompted the need to valorize these waste-cans into value-added products using the most economical and environmentally friendly techniques. In this study, the sol–gel technique was used to synthesize high-quality alumina from the aluminum waste-cans collected. From this method, the observed peaks of the synthesized alumina were identified as diaspore (α-AlO(OH)), boehmite (γ-AlO(OH)), aluminum oxide, or gamma-alumina (γ-Al₂O₃) crystalline structure and corundum. The morphological configuration, microstructure, and functional group properties of the synthesized alumina were evaluated. All the synthesized alumina exhibited a non-spherical shape and appeared to have hexagonal-like shape particles. Moreover, the XRD patterns of the synthesized alumina AL-6-30 and AL-12-30 exhibited a small angle (1–10°) with no XRD peak, which indicated a mesoporous pore structure with no long-range order. The overall results of γ-alumina synthesized from the aluminum waste-cans showed an optimal condition in producing a highly structured γ-alumina with excellent surface-area characteristics. The synthesized alumina exhibited stronger and highly crystalline functional characteristics almost comparable with the commercially available brands on the market.     

Comparative study of articaine and lidocaine without palatal injection for maxillary teeth extraction

Neonatal mortality in Jordan: secondary analysis of Jordan Population and Family Health Survey (JPFHS) data

Objective: This study aimed to analyze the 2009 Jordan Population and Family Health Survey (JPFHS) data to determine the level, trend, and distribution of neonatal mortality (NNM) in Jordan and determine its associated factors.

Methods: Nationally representative data on NNM were extracted from the JPFHS data. Using multivariate analyses, the strength of associations between 12 clinical/sociodemographic variables and neonatal mortality were quantified after controlling for potential confounders.

Results: The weighted NNM rate for 2005–2009 period was 16 deaths per 1000 live births, with the early NNM rate and late NNM rates were 10 deaths per 1000 live births and six deaths per 1000 live births, respectively. Fluctuations of NNM according to year of birth and geographic variations were noted. Risk of NNM increased among male newborns, as mother’s education level decreased, in mothers 40–49 years old, in multiple gestations-low birth weight neonates, and as birth interval was <3 years.

Conclusions: The NNR rate for 2005–2009 period of 16 deaths per 1000 live births indicates that there are opportunities to decrease it. Risk factors of neonatal mortality with respect to predictors of death during first days of life and variables related to geographic variations require particular focus to improve the quality of obstetric and neonatal health services and to decrease neonatal mortality.     

Perceived benefits of geriatric specialty telemedicine among rural patients and caregivers

Objective

Explore the perceived benefits of a Veterans Health Administration (VHA) geriatric specialty telemedicine service (GRECC Connect) among rural, older patients and caregivers to contribute to an assessment of its quality and value.

Data Sources

In Spring 2021, we interviewed a geographically diverse sample of rural, older patients and their caregivers who participated in GRECC Connect telemedicine visits.

Study Design

A cross-sectional qualitative study focused on patient and caregiver experiences with telemedicine, including perceived benefits and challenges.

Data Collection

We conducted 30 semi-structured qualitative interviews with rural, older (≥65) patients enrolled in the VHA and their caregivers via videoconference or phone. Interviews were recorded, transcribed, and analyzed using a rapid qualitative analysis approach.

Principal Findings

Participants described geriatric specialty telemedicine visits focused on cognitive assessments, tailored physical therapy, medication management, education on disease progression, support for managing multiple comorbidities, and suggestions to improve physical functioning. Participants reported that, in addition to prescribing medications and ordering tests, clinicians expedited referrals, coordinated care, and listened to and validated both patient and caregiver concerns. Perceived benefits included improved patient health; increased patient and caregiver understanding and confidence around symptom management; and greater feelings of empowerment, hopefulness, and support. Challenges included difficulty accessing some recommended programs and services, uncertainty related to instructions or follow-up, and not receiving as much information or treatment as desired. The content of visits was well aligned with the domains of the Age-Friendly Health Systems and Geriatric 5Ms frameworks (Medication, Mentation, Mobility, what Matters most, and Multi-complexity).

Conclusions

Alignment of patient and caregiver experiences with widely-used models of comprehensive geriatric care indicates that high-quality geriatric care can be provided through virtual modalities. Additional work is needed to develop strategies to address challenges and optimize and expand access to geriatric specialty telemedicine.
