Thermoplastic polyimides (TPIs) are promising lightweight materials for replacing metal components in aerospace, rocketry, and automotive industries. Key TPI attributes include low density, thermal stability, mechanical strength, inherent flame retardancy, and intrinsic fluorescence under UV light. The application of advanced manufacturing techniques, especially 3D printing, could significantly broaden the use of TPIs; however, challenges in melt-processing this class of polymer represent a barrier. This study explored the processability, 3D-printing and hence mechanical, and fluorescence properties of TPI coupons, demonstrating their suitability for advanced 3D-printing applications. Moreover, the study successfully 3D-printed a functional impeller for an overhead stirrer, effectively replacing its metallic counterpart. Defects were shown to be readily detectable under UV light. A thorough analysis of TPI processing examining its rheological, morphological, and thermal properties is presented. Extruded TPI filaments were 3D-printed into test coupons with different infill geometries to examine the effect of tool path on mechanical performance. The fluorescence properties of the 3D-printed TPI coupons were evaluated to highlight their potential to produce intricately shaped thermally stable, fluorescence-based sensors.

Introduction: Rotator Cuff Injuries (RCIs) are common shoulder injuries, and the supraspinatus muscle, which is part of the rotator cuff, plays a crucial role in shoulder abduction. The mini-open repair technique offers several advantages, including being less invasive, leading to reduced postoperative morbidity, and shorter operative times. Aim: The aim of this prospective interventional study was to assess the functional consequences of open microscopic repair and the functional implications of supraspinatus tendon repair following the procedure and during the postoperative healing period. Materials and Methods: The study was conducted at the Department of Orthopaedics at Great Eastern Medical School and Hospital in Srikakulam, Andhra Pradesh, India. The study duration was one year, from July 2020 to July 2022. A total of 120 patients aged between 20 and 60 years were included, and all surgeries were performed by the same surgeon. Patients were followed up for one year and evaluated with ConstantMurley Score (CMS) system. Patient data were analysed based on gender, age, degree of tears, clinical test results, and postoperative scores. Levene’s test was used to determine variance homogeneity, and the Student’s t-test (two-tailed, dependent) was used to determine the statistical significance of study parameters on a continuous scale within each group. Results: The study included 120 patients (84 males and 36 females), and the majority of them had traumatic tears. When data was analysed based on patient age, the majority were between 46 and 50 years (33 patients, 27%), followed by the age group of 41-45 years. At the end of one year, the outcomes were excellent in 68 patients, good in 24 patients, satisfactory in 16 patients, and poor in 12 patients. Conclusion: Based on the results of the mini-open technique, the authors concluded that mini-open rotator cuff repair resulted in superior repair integrity and shoulder function.

Introduction Retrograde transvenous obliteration (RTO) with the assistance of a balloon (BRTO) or a vascular plug (PARTO) is an established method for treating gastric varices (GVs) secondary to portal hypertension. Most of the available studies on RTO have used lipiodol along with sclerosing agents like ethanolamine oleate or sodium tetradecyl sulfate (STS). We evaluated the safety and efficacy of RTO for treating GVs using STS as a sclerosant without lipiodol. Materials and Methods Sixteen patients (nine men, age range 16–74 years) were included in this retrospective study. Twelve patients presented with acute bleeding, two with chronic bleeding, one with large varices without bleeding, and one with refractory hepatic encephalopathy (HE). BRTO was attempted in 14 patients and PARTO in 2 patients. The technical and clinical success and complications of RTO were studied. Results The RTO procedure was technically successful in 14 (14/16, 87.5%) patients, with 13 (13/14, 93%) obtaining clinical success. One patient died due to the early recurrence of bleeding. Three patients had minor intraprocedural complications. Conclusion Retrograde gastric variceal obliteration using STS is safe and technically feasible with high technical and clinical success and low complication rate.

Background Cerebral venous thrombosis is a devastating condition with, despite optimal medical management, a significant proportion deteriorating due to involvement of the deep venous system, worsening intracranial pressures, and hemorrhage. In this study, we report the characteristics, immediate and long‐term outcomes of mechanical thrombectomy (MT) using a Forgarty balloon catheter among patients with cerebral venous thrombosis. Methods A prospective study conducted at the Christian Medical College, Vellore over 5 years (February 2017–February 2022), wherein patients with cerebral venous thrombosis who had clinical deterioration despite best medical management and requiring MT were included. MT was performed through retrograde venous access through internal jugular veins using a Fogarty balloon. The primary outcome was composite end point of mortality and proportion of patients with favorable clinical response at last follow‐up, defined as a disability score in modified Rankin scale 0–2. Results Among 546 patients treated in our center during the study period, 57(10%), patients required MT. The median age of the study population was 33 years (interquartile range: 17–70 years) with equal gender predilection. Hemorrhagic venous infarction was seen in 28/57 (50%) patients. The mean duration between starting medical treatment and to MT was 43 hours (interquartile range: 5–260 hours) with the most common indication being clinical deterioration (70%). Five patients (9%) required decompressive hemicraniectomy. The mortality at discharge was 5% (n=3), and at last follow‐up visit was 7% (n=4). Younger patients without hemorrhagic venous infarction and non‐involvement of the frontoparietal lobes seem to benefit the most. Favorable functional outcome at discharge (modified Rankin scale 0–2) was seen in 65% which further improved to 77% at 1‐year follow‐up. Conclusion Balloon‐assisted MT is safe and effective in a subset of patients with severe cerebral venous thrombosis, with clinical deterioration despite optimal medical management.

Fibro adipose vascular anomaly (FAVA) is a rare type of vascular malformation with distinct clinical features. The authors here discussed the clinical, imaging, differential diagnosis, histopathological features, and treatment options of FAVA along with an illustrative case. It is important to know about this uncommon entity as this can be misdiagnosed due to the overlapping clinical features with other common entities. It is a benign condition with no proven malignant potential. There are no guidelines regarding the best treatment option.

Cerebral proliferative angiopathy (CPA), previously known as diffuse nidus-type arteriovenous malformation (AVM) is an entity distinct from cerebral AVM, characterized by multiple small arterial feeders, large-size nidus involving entire lobe or hemisphere, and no early draining veins with normal brain parenchyma interspersed between the abnormal vessels. It is usually seen in younger age group and is more common in females. We hereby report a case of diffuse cerebral proliferative angiopathy in a 29-year-old man who presented with intracranial hemorrhage. It is important to recognize this entity to avoid aggressive treatment, thus preventing permanent damage to the normal intermingled brain tissue.

Introduction: Spondylolisthesis is defined as the forward displacement of one vertebra over the vertebra below. It is often accompanied by spinal canal stenosis and compression, which is the cause of all the symptoms. Aim: To assess and study the functional outcome after decompression and Posterior Lumbar Interbody Fusion (PLIF) of isthmic spondylolisthesis of lower lumbar vertebra and to study the complications occurring with this technique. Materials and Methods: A prospective study was conducted in the Department of Orthopaedics in Justice KS Hegde Charitable Hospital, Mangalore, Karnataka, India from March 2015 to August 2016. A total of 15 diagnosed patients with Grade I and II spondylolisthesis of L4-L5 and L5-S1 vertebrae with no neurological deficits, between the age group of 25-50 were included in the study. An initial two months of conservative treatment of back physiotherapy and flexion exercises was tried. Patients who did not improve with the conservative therapy were taken up for surgery with consent. Decompression and PLIF with bone grafting with interbody cage placement and pedicle screw instrumentation was performed. The patients were discharged on postoperative day 10 after suture removal. They were reviewed at postoperative day 10, week six and week 24. The scoring of the functional outcome of the back was done as per the Modified Oswestry low back pain Disability Questionnaire. The statistical analyses were done using the repeated measures ANOVA, SPSS version 20. Results: The mean Modified Oswestry low back pain Disability score preoperatively was noted to be 42.87+/- 3.46 points. The mean Modified Oswestry low back pain Disability score at postoperative day 10 was noted to be 36.93±3.75 points. The mean Modified Oswestry low back pain Disability score at postoperative week six was noted to be 28.47±3.70 points. The mean Modified Oswestry low back pain Disability score at postoperative week 24 was noted to be 24.27±3.01 points. Improvement in the Modified Oswestry low back pain Disability scores was noted during the follow ups. Foot drop was noted in two cases postoperatively which improved during the final follow up with physiotherapy. Conclusion: Decompression and PLIF is noted to produce good to satisfactory functional results in cases of isthmic spondylolisthesis of lower lumbar vertebra.

Aim: To determine the preponderance and the distribution of pathological lesions in oral and maxillofacial region reported in and around the Madurai city. Study Design: Retrospective study on the oral and maxillofacial biopsies taken during 11 years period from 2007 to 2018 in a CSI Dental College, Madurai, Tamilnadu. A total of 1000 cases were analyzed and 904 were selected. The parameters recorded were age, sex, area, and the histopathological report obtained. Descriptive statistics was used for analysis. Result: The most common soft tissue lesion was traumatic fibroma (16.1%) and the prevalent hard tissue lesion was periapical cyst (12.7%). The more common oral malignant tumour observed was squamous cell carcinoma (7.3%) and benign tumor was ameloblastoma (5.3%). The frequently affected sites were mandible (36.1%) and buccal mucosa (19.8%). There was more predilection among male than females. The frequency of lesion is common in age group of 31-60 years. A considerable similarity was observed between age, type of lesion and its location. Conclusions: This study evaluated chronic periapical lesions were the most common hard tissue lesions and fibromas in soft tissue category. The idea of this histopathological study concludes on the requirement for biopsy to rule out type of the lesion and its severity to start up the earlier management.

Introduction: The third molar is the most frequently impacted tooth with a frequency of occurrence generally reported to be from 18 to 32%. It is considered impacted when its eruption into normal functional occlusion has been interfered with by other teeth, overlying bone or soft tissue and when it is not fully erupted by its expected age of around 20 years. Racial differences affect the pattern of impaction. There is a lacunae of literature on the pattern of mandibular third molar impaction in Tamil population. Aim: To investigate the prevalence of pattern of third molar impaction among the population in Madurai. Materials and Methods: A retrospective cohort study was conducted. The first 1000 OPGs (Orthopantamograms) were taken at the Department of Oral Medicine and Radiology, CSI College of Dental Sciences and Research from August to December 2018 of Madurai population aged between 20 and 40 years old. Data include angle, level and position of impaction, proximity to inferior alveolar nerve and dental caries in second molar and/or third molar. Results: The average age of subject with mandibular third molar impaction is 30.5 years. The most common occurring mandibular impaction is mesioanglar (60%), Level A (71%), Class II (50%) without involving the inferior alveolar nerve (33%) and dental caries in 20% of second and/ or third molar. Conclusion: Mandibular third molar impactions are one of the common developmental condition in this modern civilization. Assessing the third molar and prognosis of its eruption is mandatory for better patient management because of numerous complications associated with unerupted third molar.

Summary: Nowadays, future workload prediction is an important requirement in cloud data centers to maintain flexibility and scalability of resources. However, due to unexpected peaks, drops in workload, noise, and redundancy in user requests, there is a considerable variance in resource demands, making it difficult to accurately predict workloads. Therefore, a self‐attention‐based progressive generative adversarial network (SAPGAN) optimized with Giza Pyramids Construction Algorithm (GPCA)‐based workload prediction is proposed for Sustainable Cloud Data Centers (CDC). At first, redundant data in historical data obtained through CDC are filtered utilizing Markov chain random field (MCRF) co‐simulation method. These pre‐processed historical data are supplied to the SAPGAN. The SAPGAN weight parameters are optimized by GPCA. The proposed method is analyzed using 2 benchmark datasets: HTTP traces from Saskatchewan and NASA. The simulation is implemented in JAVA. The performance metrics is examined to verify the efficacy of the proposed technique. The performance of the proposed approach provides 28.70%, 11.87%, and 14.79% higher accuracy; 30.15%, 11.72%, and 18.34% lesser energy consume for the dataset of NASA; and 5.32%, 2.45%, and 5.67% higher accuracy; 12.36%, 24.24%, and 34.16% lesser energy consume for the dataset of Saskatchewan HTTP traces compared with existing methods, such as auto‐adaptive learning in a dynamic cloud environment (AADEA‐WLP‐CDC), a neural network model depending on biphase adaptive learning for anticipating cloud data center workload (BALNN‐WLP‐CDC) and multiple scale ensemble of deep learning framework for multistep‐ahead cloud workload prediction (EMD‐LSTM‐GAN‐WLP‐CDC).

Internal fixation of femoral neck fractures has been always debatable. Parallel screws though are a frequent modality of fixation, they have a poor outcome in 46% of cases clinically. The fixation failure can be reduced significantly by optimizing the primary stability of the internal fixation construct. We treated 12 patients who presented with fracture neck of the femur by biplane double support fixation (BDSF) technique. All patients achieved fracture union without any complications and were followed up for 12 months. The results with BDSF are far more successful than the conventional method of fixation. There were no instances of fixation failure in our series of 12 cases. [ABSTRACT FROM AUTHOR]

The synthetic feasibility and excellent luminescence features of organic molecules attracted much attention and were eventually found useful in lighting applications. In this context, a solvent‐free organic liquid having attractive thermally activated delayed fluorescence features in bulk along with high processability has prime importance. Herein, we report a series of naphthalene monoimide‐based solvent‐free organic liquids exhibiting cyan to red thermally activated delayed fluorescence with luminescence quantum yields up to 80% and lifetimes between 10 to 45 μs. An effective approach explored energy transfer between liquid donors with various emitters exhibiting tunable emission colors, including white. The high processability of liquid emitters improved the compatibility with polylactic acid and was used for developing multicolor emissive objects using 3D printing. Our demonstration of the thermally activated delayed fluorescence liquid will be much appreciated as a processable alternate emissive material suitable for large‐area lighting, display, and related applications.
