Osteoarthritis is a degenerative joint disease characterized by progressive loss of articular cartilage. Risk factors include age, obesity, joint injury, genetics, and occupation. Symptoms include joint pain, tenderness, and stiffness. Treatment focuses on reducing pain and inflammation through measures like exercise, weight loss, bracing, oral medications, and injections. Surgery is considered if more conservative treatments fail to improve function and quality of life.

Dr. A. Mohan Krishna is a consultant orthopaedic surgeon based in Hyderabad, India who specializes in trauma, arthroscopy, and arthroplasty. He operates at Apollo Hospitals and maintains a private practice through his websites, where he treats patients for conditions like osteoarthritis. Osteoarthritis is a degenerative joint disease that affects cartilage and surrounding tissues in weight-bearing joints. As the condition progresses, cartilage breaks down and bone rubs against bone, causing pain, swelling, and stiffness. Dr. Krishna's treatments for osteoarthritis include medications, physiotherapy, nutraceuticals, viscosupplementation injections, steroid injections, and arthroscopic procedures to relieve pain and mechanical symptoms.
This is a short presentation on intraarticular knee injection. This presentation gives brief idea about hyaluronic acid injection used for management of osteoarthritic pain.
Hyaluronic acid is substance similar to the synovial fluid which is present in our knees. It is a viscosupplementation injection that lubricates and helps to cushion the joint. The mechanism of action of the injection is it stimulates the natural lining of the joint to produce natural joint fluid, reduces joint pain by coating the damaged joint lining and by its anti inflammatory action.
This document summarizes the management of osteoarthritis (OA), including both non-surgical and surgical options. For non-surgical treatment, it recommends medications like paracetamol, NSAIDs, tramadol, and topical creams. It also mentions supplements like glucosamine/chondroitin and corticosteroid injections. For surgical management, it describes arthroscopy, osteotomy, arthroplasty including hip replacement, and arthrodesis. Complications of surgery are also outlined. The goal of treatment is to relieve pain, protect joint function, and improve quality of life.
Osteoarthritis is a progressive disorder caused by loss of cartilage in joints. It has two classifications: primary which occurs with aging or for unknown reasons, and secondary which results from other diseases or injuries. Risk factors include age, sex, obesity, repetitive joint stress, and other medical conditions. Symptoms include pain that worsens with use and improves with rest, stiffness, swelling, and loss of function. Diagnosis is based on history, examination findings like limited range of motion, and x-rays showing bone spurs and joint space narrowing. Treatment focuses on exercise, weight loss, medications like acetaminophen, NSAIDs, and corticosteroid injections, and possibly surgery like joint replacement for severe cases.
Osteoarthritis is a common form of arthritis where cartilage in joints breaks down over time. It causes pain, stiffness, and loss of mobility in joints like the hands, hips, and knees. While there is no cure, treatments can help manage symptoms and maintain activity. For mild cases, initial treatments include exercise, weight loss, heat/cold therapy, and over-the-counter pain relievers. For moderate to severe cases, stronger medications, cortisone shots, and surgery may be needed to relieve pain and disability. Joint replacement surgery can help severely affected patients resume an active lifestyle.

Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆Sérgio Sacani
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4

Signatures of wave erosion in Titan’s coastsSérgio Sacani
The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it isunclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theo-retical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion,but the observational evidence of waves is indirect, and the processes affecting shoreline evolution on Titanremain unknown. No widely accepted framework exists for using shoreline morphology to quantitatively dis-cern coastal erosion mechanisms, even on Earth, where the dominant mechanisms are known. We combinelandscape evolution models with measurements of shoreline shape on Earth to characterize how differentcoastal erosion mechanisms affect shoreline morphology. Applying this framework to Titan, we find that theshorelines of Titan’s seas are most consistent with flooded landscapes that subsequently have been eroded bywaves, rather than a uniform erosional process or no coastal erosion, particularly if wave growth saturates atfetch lengths of tens of kilometers.
