Authors: Cooke Hayden L. , Schaeffer Christine V. , Gabig Andrew M. , Karzon Anthony , Savani Ujjawal , Gottschalk Michael B. , Wagner Eric R. 
Published: August 2023

Case:
A 62-year-old woman presented with wrist pain secondary to a distal radius fracture malunion 4 months after a fall onto an outstretched hand. She was not an ideal candidate for osteotomy and bone graft because of the degree of displacement and osteoporosis, so after nonoperative treatment was unsuccessful, she was offered total wrist arthroplasty (TWA) or arthrodesis and opted for TWA.

Conclusion:
At 14-month follow-up, the patient reported significant improvement in her pain and function. The current generation of TWA implants may allow use in the management of symptomatic distal radius malunions in older, low-demand patients.

Authors: Arif Haad , Molina Steven , LeBrun Christopher 
Published: August 2023

Case:
An 18-year-old male patient presented with a closed fracture of the left tibia and fibula and a bent intramedullary nail after a repeat motorcycle accident. The patient was 5 weeks postoperative from intramedullary nailing of a closed left tibia fracture. The site of angulation of the tibial nail was noted to be more proximal than the fracture site. Partial sectioning of the nail through an osteotomy permitted the removal of the nail and revision tibial nailing.

Conclusion:
This is the first reported use of an osteotomy and partial sectioning during the extraction of a bent tibial intramedullary nail.

Published: August 2023

Abstract
In the present report, the facile co-precipitation technique was used to synthesis undoped ZnO NPs, Cd-doped and Sn-doped ZnO NPs. The XRD patterns shows that the all-synthesized samples were confirmed the hexagonal crystal structure of ZnO NPs, which reveals that, there were no impurities in the doped materials. The FT-IR studies confirms the phase formation of ZnO and also shows the confirms the functional groups present in the synthesized samples. From UV-DRS, the band gap of pure ZnO NPs is decreased from 3.38 eV to 3.21 eV by adding the dopant Cd. Whereas, the addition of Sn decreases the band gap to 3.30 eV. From PL spectrum, the near band emission (393 nm) and blue emission (451 and 468 nm) were observed. SEM images show the considerable change in morphology from the flakes like morphologies to non-uniform surface of nanostructured morphology and homogonous spherical shaped nanostructured morphology when Cd and Sn are added as dopants. The photocatalytic activity of ZnO NPs, Cd-doped and Sn-doped ZnO NPs were analysed by the degradation of Eosin Yellow (EY) and Direct Blue 15 (DB-15) under UV light irradiation. The prepared Cd-doped ZnO NPs shows a high photocatalytic activity compared with pure ZnO NPs and Sn-doped ZnO NPs. The result revealed that, as-prepared Cd-doped ZnO NPs found to have efficient degradation candidate materials.

Published: August 2023

Abstract
Quadriceps strength deficits are known for patients with knee osteoarthritis (OA). Hamstring muscles has been less often investigated and findings are not as clear as for knee extensors. In regard of OA, the neuromuscular function in the sense of Adaptive Force (AF) has never been examined before. The maximal isometric AF (AFisomax) was previously considered to be especially vulnerable to disruptive stimuli and, therefore, was assumed to show deficits in OA patients. The present study investigated AF parameters (AFisomax and maximal AF (AFmax)) as well as the maximal voluntary isometric contraction (MVIC) of hamstring muscles bilaterally of 20 knee OA patients (ART) compared to 19 asymptomatic controls (CON). For each side, MVIC was captured before and after AF measurements. Five AF trials were performed using a pneumatically driven device. Participants should maintain an isometric position despite an increasing load of the device. After reaching AFisomax, the muscle merged into eccentric muscle action whereby the force increased further to AFmax. All torque parameters (normalized to body mass) were significantly lower in ART vs. CON for both sides with almost always very large effect sizes. MVIC deficits (difference between ART and CON) amounted −28% for the more and −30% for the less affected/asymptomatic side. AFmax showed deficits of −36% and −32% and AFisomax of −37% and −24%, respectively. The reduction of AFisomax was not as high as expected, especially related to MVIC or AFmax. The ratio AFmax to MVIC was significantly lower for the more affected side of ART (84 ± 17%) vs. CON (95 ± 7%). The force rise per degree of knee extension was significantly lower for ART vs. CON. The results suggest that in general hamstrings strength deficits are present in OA patients. The hypothesized stronger deficit in maximal holding capacity (AFisomax) in ART vs. CON was not confirmed. It is suggested this might presumably result from the seating measurement position. Knee strain relief might have been present thereby which could have reduced inhibitory nociceptive effects. Importantly, OA patients seem not to be able to generate as much of their possible maximal strength during eccentric action as controls and their force rise per degree of knee extension seems to be diminished. The role of force development especially under muscle lengthening should be considered in further studies to get more specific insights into this aspect of neuromuscular control.

Abstract
Check dams are main structure to soil and water protection and source of data to calculated erosion and sediment trapping rates at a sub-basin. Because they retain the main part of the sediment product in their reservoirs. Aim of this research was compare three topographic methods to assess how the measures total sediment at location in southeastern Iran. For this aim, we measured the volume of sediment deposited by 25 check dams built during the two years back. We print out data of topographical survey applying a file work technical, with a nicety to calculate the dimensions of the sediment deposited behind of each check dam. The results were also compared with three streamlined methods that regard to the volume of trapped sediment as a unmixed geometric shape. Results shows that the total volume of sediment deposited behind the check dams are 10299.2, 8211.2 and 6903 m3 according to the method A, B and C, respectively. Correlation between method A and other is well and signification at the 0.0l level. There was no significantly influenced between contain sediment deposited volumes behind of check dam, TE, SY, TSY by two methods, at a assurance level of 95%, but there was significantly influenced between amounts of ES.

Published: August 2023

Abstract
Percutaneous nephrolithotomy (PCNL) is considered gold standard treatment of renal stones larger than 20mm. Several studies have shown that ultrasound guidance during this procedure is more effective and safer than fluoroscopy. A higher body mass index (BMI) can make ultrasound-guided renal access more difficult and unsuccessful. We present a prospective analysis and comparison of ultrasound-guided PCNL in patients with normal and increased body mass index. We performed a prospective comparison of patients who underwent ultrasound-guided PCNL to remove renal stones by a single surgeon between 2020 and 2022. Patients with BMIs greater than 30 (mean 33.87- Obese) were compared to those with BMIs less than 30 (mean 25.69- non-Obese). Demographic, perioperative, and follow-up data were collected, analyzed, and included in this study. Total of 98 consecutive patients, with 49 patients in each group. No statistically significant differences were observed in terms of stone volume (p = 0.085), stone density (P = 0.5590), location of renal access (P = 0.108), surgery duration (P = 0.38), blood loss (P = 0.54), or laboratory changes after surgery (P = 0.60). 87.76% of obese patients were stone-free per CT scan at follow-up, compared to 73.47% of normal-weight patients (P = 0.1238). According to Clavien Dindo classification, six patients in the non-obese group experienced grade II (10%) and grade III (2%) complications, as opposed to six patients in the obese group with grade I (2%), grade II (6%), and grade III (2%) complications. There was no significant correlation between body mass index and the success or safety of ultrasound-guided PCNL. Although more challenging, a higher BMI should not be an impediment to performing this approach. This method is safe, with no increased incidence of postoperative complications or compromise in stone-free status post-operatively and can diminish or avoid both patient’s and medical team’s exposure to ionizing radiation.
A genetic-based approach for vehicle routing problem with fuzzy alpha-cut constraints
Authors: Lee Amy Hsin-I , Kang He-YAU 
Published: August 2023

Abstract

In today’s business environment, logistics and supply chain management are especially important for the timely delivery of materials and goods. Delivery must not only be fast, it also needs to be performed within a specific time frame. Therefore, this study examines a vehicle routing problem (VRP) that considers multiple goals and allows vehicles to reach their destinations within a time window with a crashed traveling time. Two objectives are considered, the minimization of total cost and the maximization of customer satisfaction. Firstly, a fuzzy multi-objective linear programming (FMOLP) model with fuzzy alpha-cut constraints is proposed for multi-objective optimization, and then an improved genetic algorithm (IGA) is constructed to solve large-scale problems. The performances of the proposed methods are evaluated through several case studies. Design of experiments and sensitivity analysis are applied to evaluate the performance and robustness of IGA. The results show that both the FMOLP and IGA are effective, and the IGA can efficiently obtain a near-optimal solution.
Advances in Our Understanding of Locomotory Behavioural Response of Teratorhabditis Palmarum Nematode
Authors: jamal wajih 
Published: August 2023

Abstract

Locomotion is essential to most living organisms. The nematode Teratorhabditis palmarum (Gerber & Giblin-Davis, 1990), must be able to accommodate its locomotory gait to its physical environment. Particularly, when crawl on a solid surface, it shows forward movement as the contraction waves propagates from anterior to the posterior region. In the present study, we analyzed the locomotory behavior of T. palmarum on agar by using computational worm-tracking system and mathematical tools. Our tracking system was made to assist worms that travel a vast area with recurrent turns and reversals at high speeds. The locomotory parameters studied were velocity, wavelength, amplitude, angle of bending, curvature map, forward, reversal, omega and pause that was extracted from a two min video recording. Here, we examined the locomotory behaviour (movement and wave characteristic) of two, six and ten days old nematodes. In movement characteristic, except pause which increases; forward wave, backward wave and omega wave decrease significantly. In wave characteristic, wavelength and amplitude increase while average velocity and bending angle decrease significantly. Locomotion was observed between various age groups and it was concluded that as animals aged, mild locomotory deficits appeared that were enough to reduce behavioral activity. This study is important in controlling nematode, which causes the diseases especially Plant parasitic nematodes, which affects the agricultural crops and we easily manage to control the population.

Published: August 2023

Abstract
Background
The evolutionary and ecological success of insects may in part be due to their sophisticated and highly evolved chemosensation systems. Insect chemosensation genes form some of the largest multigene families known and are important targets for reverse genetics approaches to study the relationship between ecology, evolution and genomics. Here we use genomics, phylogenetics, transcriptomics and differential expression analyses to investigate the chemosensory gene repertoire of Sirex noctilio, one of the most economically important pests of Pinus plantations in many parts of the world.
Results
A total of 129 chemosensation genes, including 45 ORs, 12 GRs, 48 IRs, 1 SNMP, 14 OBPs and 9 CSPs, were identified and phylogenetically characterised in the genome of S. noctilio. RNA-sequencing of olfactory and non-olfactory adult and pupa S. noctilio tissues enabled expression profiling of the identified chemosensation genes. The identified antennae-, ovipositor- and leg-biased chemosensation genes are of particular interest due to their potential olfactory and oviposition function, and the sexual dimorphism of these tissues.
Conclusions
Tissue- and sex-biased chemosensation gene expression were observed throughout the 15 tissue transcriptomes investigated. This study broadens our understanding of the peri-receptive events of S. noctilio chemosensation and strengthens the foundation for chemical ecology studies and functional deorphanisation of S. noctilio chemosensation genes. The phylogenetically basal position of this woodwasp within the Hymenoptera also informs the evolution of the multigene families associated with chemosensation in this ecologically and economically important order.

Published: August 2023

Abstract
Background
Anastomotic leakage (AL) is a severe complication following esophagectomy with high mortality. Perioperative decreased serum albumin level is considered a predictive of AL, however, its impact on AL incidence in patients treated with neoadjuvant chemotherapy (NCT) followed by minimally invasive esophagectomy (MIE) is not well defined.
Methods
The data of 318 consecutive esophageal cancer patients who underwent MIE were collected retrospectively from January 2021 to December 2021. The perioperative level of albumin was detected and the baseline of altering levels for albumin was established. The incidence of postoperative complications and survival rate were analyzed between groups.
Results
After exclusion, 137 patients were enrolled and assigned to more decreased albumin (MA) and less decreased albumin (LA) groups. The levels of albumin descended significantly after MIE (p < 0.0001). There was no significant difference in the clinicopathologic characteristics or surgical outcomes between groups. The incidence of postoperative AL was 10.2% in MA group and 1.4% in LA group (p = 0.033). Three patients died due to AL in MA group, while no mortality was observed in LA group (p = 0.120). The rate of other postoperative complications was similar between groups. Progression-free survival (PFS) in LA group was a little higher than that in MA group, but it was no significant difference (p = 0.853). Similarly, no difference was observed in overall survival (OS) between groups (p = 0.277).
Conclusions
Severely deficient serum albumin after MIE was an indicator of AL in esophageal cancer patients treated with NCT.

Abstract
Background: Cholangiolocarcinoma (CLC) is an extremely rare tumor classified as a subtype of small duct-type intrahepatic cholangiocarcinoma (iCCA). There are few detailed reports on CLC, and the prognostic impact of tumor heterogeneity is not clear.
Methods: Between April 2006 and June 2022, 14 patients were pathologically diagnosed with CLC through immunohistochemical analysis of their molecular and biological features. Clinicopathological features and prognoses were evaluated retrospectively. Additionally, we compared the tumor heterogeneity, classifying them into pure and partial types according to the CLC component proportion in a single tumor.
Results: Chronic liver disease was observed in nine patients (64.3%). All tumors were mass-forming, and pathological R0 resection was achieved in 11 patients (78.6%). Tumor heterogeneity was classified as pure in 11 (78.6%) and partial in three (21.4%) patients. The median follow-up was 59.5 months (12–114 months). There was no difference in the 5-year disease-specific survival rates between the pure and partial (90.0% vs. 100.0%; P = 0.2000) types, but they were significantly higher in the R0 resection group than in the R1 resection group (100.0% vs. 50.0%; P = 0.0253).
Conclusions: Our results suggest that CLC has a good prognosis after curative resection, regardless of the proportion of CLC components in a single tumor.

Published: August 2023

Abstract
Background: Total hip arthroplasty (THA) for the treatment of hip dysplasia, which disproportionately impacts the younger population, has been shown to be an effective intervention to restore functionality and improve quality of life. However, it is unclear whether these outcomes can be just as beneficial in treating hip dysplasia when it presents in older patients. Therefore, we sought to investigate and compare the pre-and postoperative outcomes of THA for hip dysplasia in older adults to those with end-stage osteoarthritis (OA).
Methods: A prospectively collected database from a single institution was queried from September 1st, 2016 to October 31st, 2021 to identify 323 unilateral THA patients age 50 years or older and separated into 2 groups given a primary diagnosis of hip dysplasia (n = 90 patients) or osteoarthritis (n = 233 patients). Preoperative and minimum 1-year postoperative outcomes were then compared using the Hip Outcome Score (HOS), Hip Disability and Osteoarthritis Outcome Score (HOOS), University of California-Los Angeles (UCLA) activity score, Pain Catastrophizing Score (PCS), and the Depression Anxiety Stress Scale (DASS).
Results: The outcomes between the groups showed no significant differences in their pre-and postoperative HOOS (P = 0.22 and P = 0.63 respectively), DASS Anxiety (P = 0.81 and P = 0.29 respectively), and the DASS Stress Score (P = 0.17 and P = 0.28 respectively). Patients with hip dysplasia reported significantly better preoperative (10.1 vs 12.9, P <0.001) and postoperative (5.7 vs 7.2, P = 0.01) DASS Depression Scores but scored significantly lower in the pre-operative HOS (35.4 vs 42.2, P <0.05). Outcomes for the UCLA activity score uncovered that patients with hip dysplasia scored significantly higher preoperatively (4.8 vs 4.2, P = 0.02), but no significant difference was seen postoperatively (4.6 vs 5.0, P = 0.11). The PCS noted no significant differences preoperatively (23.2 vs 21.0, P = 0.12). However, the hip dysplasia group has significantly better postoperative scores (6.6 vs 10.0, P = 0.02).
Conclusion: Our investigation demonstrates THA as an excellent surgical option for treating hip dysplasia when presenting in older adults and can yield comparable outcomes as those noted in THA performed for OA in older adults.

Authors: Huo Zhenhui , Hao Kuo , Fan Chongyi , Li Kehan , Li Ming , Wang Fei , Niu Yingzhen 
Published: August 2023

Abstract
Background: Posterior cruciate ligament (PCL) injuries are common ligament injuries of the knee, and previous studies often focused on the associations between the morphology of the knee and PCL injuries. Studies on the correlation between PCL injuries and patellofemoral alignment are limited.
Methods: This retrospective study included 92 patients with PCL injured and 92 patients with PCL intact. Measurement parameters were compared between the two groups, including patellar tilt angle, congruence angle, patellar height, hip-knee-ankle angle, lateral trochlear inclination,femoral condyle ratio, bicondylar width, intercondylar notch width and index, notch angle, trochlear facet asymmetry, and trochlear sulcus depth and angle. Independent risk factors associated with PCL injuries were identified by logistic regression analyses.
Results: In the PCL injured group, the patellar tilt angle was significantly larger (13.19 ± 5.90° vs. 10.02 ± 4.95°, P = 0.04); the intercondylar notch angle was significantly lower (60.97 ± 7.83° vs. 67.01 ± 6.00°, P = 0.004); the medial and lateral femoral condyle ratio were significantly larger (0.63 ± 0.64 vs. 0.60 ± 0.56, P = 0.031; 0.65 ± 0.60 vs. 0.58 ± 0.53, P = 0.005) than in the PCL intact group. There were 11 patients with patellar dislocation in the PCL injured group, accounting for 12%. In these patients, the patellar height was higher (1.39 ± 0.17 vs. 1.09 ± 0.25, P = 0.009); the trochlear sulcus angle was larger (157.70 ± 8.7 vs. 141.80 ± 8.78, P < 0.001); and the trochlear sulcus depth was shallower (3.10 ± 1.20 vs. 5.11 ± 1.48, P = 0.003) than those in the patients without patellar dislocation. Multivariate analyses showed that patellar tilt angle (each increase 1 degree, OR = 1.14) and intercondylar notch angle (each increase 1 degree, OR = 0.90) were independent risk factors for PCL injuries.
Conclusion: The patients with PCL injuries had larger patellar tilt angles, lower intercondylar notch angles, and longer posterior femoral condyles than patients with PCL intact. The larger patellar tilt angle and lower intercondylar notch angle might be risk factors for PCL injuries.
