The research study attempts to ascertain the mechanical performance of asphalt concrete, using reclaimed asphalt concrete pavement (RAP) and recycled concrete aggregate (RCA) blends with polyethylene terephthalate (PET) as a modifier. The influence factors were evaluated, including RAP/RCA ratios and PET contents on static and cyclic performances. The static performance was assessed through the indirect tensile strength (ITS) tests, while the cyclic performance was assessed through the indirect tensile resilient modulus (ITMR), indirect tensile fatigue life (ITFL), and wheel tracking tests. Compared to asphalt concrete using natural aggregate (NA), the ITMR of RAP-RCA-PET asphalt concretes was higher when PET contents were between 0.2% and 0.6% for RAP/RCA = 80/20. The ITFL of RAP-RCA-PET asphalt concretes was found to be higher than that of NA asphalt concrete when PET contents ranged from 0.2% to 0.6% for RAP/RCA < 90/10. The ITFL was also higher when PET content was between 0.4% and 0.6% for RAP/RCA = 100/0. RAP-RCA-PET asphalt concretes exhibited lower rut depth than NA asphalt concrete with RAP/RCA = 90/10 and 60/40 at PET contents of 0.4% to 1.0% and with RAP/RCA = 80/20 at PET contents of 0.2% to 1.0%. The RAP/RCA = 80/20 and PET content = 0.6% were found to be the best ingredient in term of both fatigue cracking and rutting resistances. As per the systematic analysis, the fatigue distress models of RAP-RCA-PET asphalt concretes for various PET contents were developed in term of ITFL and tensile strain (𝜀𝑡) relationship and useful for mechanistic design. The results of this research will contribute to promoting RAP-RCA-PET asphalt concrete as a greener material in pavement construction. Doi: 10.28991/CEJ-2024-010-11-08 Full Text: PDF

Potato is a horticulture plant that contains complex nutrition like high carbo and phosphor. Low potato productivity can be caused by the use of low-quality (degenerate) seed potatoes that are conventionally propagated by the farming community. Tissue culture techniques can be an effective solution to produce healthy and disease-free seed potatoes. This study aimed to examine the combination treatment between photoperiod (P) and Kinetin (K) on the growth of granola potato micro cuttings in vitro. This research was conducted at the Plant Tissue Culture Laboratory, Faculty of Agriculture, Malikussaleh University, from February to April 2022. This study used a split-plot design in a completely randomized design. The main plot was photoperiod (0 hours ligth and 24 hours light). The sub plot was concentration of kinetin (0; 2; 4 ppm). The resut showed that there was an interaction between the treatment of photoperiod and kinetin concentration on the growth of ‘Granola’ potato micro cuttings on the variables of shoot growth percentage, number of shoots, number of leaves, and number of roots. The best treatment was 24 hours of light + 4 ppm kinetin.

Published: December 2024

OBJECTIVE
Patients with sellar lesions compressing the optic nerve sometimes perceive visual improvement after lesion resection, despite the absence of visual impairment on preoperative ophthalmological examination. This study investigated the indicators of latent visual impairment in patients with sellar lesions.

METHODS
Forty-five patients who underwent surgery for sellar lesions compressing the optic nerve with no preoperative visual abnormalities and no change in visual assessment between pre- and postoperative ophthalmological examinations were divided into two groups: 1) patients who perceived recovery of visual function after lesion resection (the improved group), and 2) patients who did not (the unaffected group). Four assessments of optic nerve bending were compared between the groups: 1) coronal optic nerve bending height (CONBH), defined as the vertical distance between the highest apex of the bending optic chiasm and the line connecting the endpoints of the optic nerve on the coronal image; 2) coronal optic nerve bending angle (CONBA), defined as the internal angle formed by the intersection of lines parallel to the left and right optic nerves at the greatest bending section of the optic chiasm on the coronal image; 3) sagittal optic nerve bending height (SONBH), defined as the vertical distance between the highest apex of the bending optic chiasm and the extension line of the optic nerve course in the optic canal on the sagittal image; and 4) sagittal optic nerve bending angle (SONBA), defined as the internal angle formed by the intersection of the line connecting the optic canal entrance level and the highest apex of the bending optic chiasm and the extension line of the optic nerve course in the optic canal on the sagittal image.

RESULTS
Of the 45 patients, 21 were assigned to the improved group and 24 to the unaffected group. CONBH, CONBA, SONBH, and SONBA showed significant differences between the groups (all p < 0.001). Multivariate logistic regression analysis revealed that only SONBA was a significant independent predictor of perceived visual recovery after resection of sellar lesions (OR 2.29, 95% CI 1.03–5.10; p = 0.042). The optimal cutoff point of SONBA for perceiving visual recovery was identified as 30° (specificity 1.000, sensitivity 0.952).

CONCLUSIONS
Angle assessment of optic nerve bending due to compression caused by sellar lesions on the sagittal image may be useful in identifying sellar lesions with latent visual impairment.

OBJECTIVE
Patients undergoing anterior/posterior lumbar fusion surgery can undergo either a single-stage or multistage operation, depending on surgeon preference. The goal of this study was to assess different patient outcomes between single-stage and multistage lumbar fusion procedures in a multicenter setting.

METHODS
The Michigan Spine Surgery Improvement Collaborative database was queried for anterior/posterior lumbar fusion surgeries between July 2018 and January 2022. Patients who underwent either single-stage or multistage procedures were included. For multistage procedures, the first surgery included both anterior lumbar interbody fusions and lateral lumbar interbody fusions. Primary outcomes included postoperative complications and improvement in patient-reported outcomes: Patient-Reported Outcomes Measurement Information System Physical Function, EQ-5D, and satisfaction. The two cohorts were propensity score matched, while Poisson generalized estimating equation models were used for multivariate analyses.

RESULTS
After one-to-one propensity score matching, 355 patients were identified in the single-stage and multistage cohorts. Single-stage procedures were associated with a lower risk of complications (p = 0.024), fewer emergency department visits (p = 0.029), and higher patient satisfaction after 1 year (p = 0.026) and 2 years (p = 0.007), compared with multistage procedures. After adjusting for baseline patient and operative characteristics, patients undergoing multistage procedures had a higher risk of complications (relative risk [RR] 1.17, 95% CI 1.02–1.34; p = 0.026), were less likely to be satisfied after 1 year (RR 0.83, 95% CI 0.74–0.93; p < 0.001), and were less likely to experience improvement in back pain after 90 days (RR 0.86, 95% CI 0.75–0.99; p = 0.039) and 2 years (RR 0.76, 95% CI 0.60–0.96; p = 0.023).

CONCLUSIONS
The authors observed that patients who undergo lumbar fusion surgery using a multistage approach have higher postoperative complication rates and are less likely to report satisfaction compared with a matched, single-stage procedure cohort.
Assessing the prognostic impact of body composition phenotypes on surgical outcomes and survival in patients with spinal metastasis: a deep learning approach to preoperative CT analysis
Authors: Khalid Syed I. , Massaad Elie , Shin John H. 
Published: December 2024

OBJECTIVE
The prognostic significance of body composition phenotypes for survival in patients undergoing surgical intervention for spinal metastases has not yet been elucidated. This study aimed to elucidate the impact of body composition phenotypes on surgical outcomes and 5-year survival.

METHODS
The records of patients treated surgically for spinal metastases between 2010 and 2020 were retrospectively evaluated. A deep learning pipeline assessed preoperative CT scans obtained within 3 months of surgery and identified muscle and fat content and composition. These data were used to categorize patients into 4 body composition phenotypic groups: 1) not sarcopenic, not obese; 2) sarcopenia alone; 3) obesity alone; and 4) sarcopenic obesity (SO). The groups were matched using a comprehensive propensity-matching procedure. Rates of postoperative outcomes and survival were evaluated. Cox proportional hazard models were used to evaluate the influence of body composition phenotypes on 5-year survival. Kaplan-Meier plots were used to evaluate survival probability further.

RESULTS
Following a propensity-matching procedure, 102 matched patient records were identified (not sarcopenic, not obese, n = 24; sarcopenia alone, n = 27; obesity alone, n = 37; and SO, n = 14). SO was found to be associated with a significantly increased mortality risk within 60 months (HR 3.27, 95% CI 1.43–7.48). Kaplan-Meier plots demonstrate evident divergence in survival probability within 5 years among patients in the SO group compared to the others (log-rank test, p = 0.022). Additionally, time to death was also lower in patients with SO (p = 0.018). Significant differences in postoperative ambulation rates were noted among patients with SO (p = 0.048), whereas no preoperative difference existed (p = 0.12). No significant differences in postoperative disposition, length of hospital stay, wound-related complications, or inpatient medical complications were otherwise noted (p > 0.05).

CONCLUSIONS
This study identifies SO as a distinct prognostic factor for increased mortality risk in patients undergoing surgery for spinal metastases, highlighting the complex interplay between body composition and patient outcomes. These findings advocate for integrating body composition analysis into preoperative assessment and tailored postoperative care strategies, promoting personalized treatment plans to improve survival and quality of life for this vulnerable patient population.
Research Priorities and Needs in Global Migrant Health: A Systematic Review of Reviews
Authors: Simkhada Padam , Mahato Preeti , van Teijlingen Edwin , Regmi Pramod , Aryal Nirmal , Manandhar Shraddha 
Published: December 2024

_Aim_: Worldwide, the number of migrants is still increasing. Most research is focused on refugees and irregular migrants to high-income countries, with less focus on migrants moving between low and middle-income countries. As migrant health is a public health priority, there is a need for conducting quality research and gathering information on the health needs of migrants. This review of reviews was undertaken to find research priorities, needs, and identify gaps in the literature on migrant health.

_Methods_: A systematic search of several databases using various combinations of search terms found 1,769 articles (after removing duplicates). Twenty-two studies were selected based on inclusion and exclusion criteria. Data were extracted and synthesised and presented in a narrative analysis of common themes.

_Results_: Most of the included articles were systematic reviews conducted in high-income countries and among heterogenous groups of migrants. The major health themes explored in these reviews were: health service use and accessibility; mental health; perinatal health; sexual and reproductive health; and occupational health. In our systematic review, we explored challenges to and limitations of existing migrant health research and offered suggestions for future research.

_Conclusion_: Migration and health are both complex phenomena, and so is the relationship between them. Most studies were cross-sectional; hence, there is a gap that should be filled with mixed-methods and longitudinal studies to further our knowledge of migrant health, and more research is needed on unexplored health issues. Priority should be given to conducting research in the countries of origin and in low-income countries.
