Coronal Plane Alignment of the Knee (CPAK) Type Shifts Toward Constitutional Varus with Increasing Kellgren and Lawrence Grade: A Radiographic Analysis of 17,365 Knees.

Background: Studies investigating constitutional alignment across various grades of osteoarthritis (OA) are limited. This study explored the distribution of Coronal Plane Alignment of the Knee (CPAK) types and associated radiographic parameters with increasing OA severity.

Methods: In this retrospective cross-sectional study, 17,365 knees were analyzed using deep learning software for radiographic measurements.

GLP-1RA based therapies in the young and old.

Purpose Of Review: Obesity is recognized as a "gateway" chronic, progressive disease of dysfunctional adipocytes. Glucagon-like peptide-1 receptor agonist-based therapies (GLP1BTs), including glucagon-like peptide-1 receptor agonists (GLP-1 RAs) with/without glucose-dependent insulinotropic polypeptide (GIP), have demonstrated clinically significant weight loss and health gains in adults, hence interest in using them in younger and older people. Therefore, reviewing the role of GLP1BTs in these populations is pertinent and timely.

Baseline characteristics of patients with degenerative cervical myelopathy in Australia: analysis from the MYelopathy NAtural History registry.

Background: Degenerative Cervical Myelopathy (DCM) is the most common cause of non-traumatic, chronic spinal cord dysfunction worldwide, causing debilitating disability with a diminishing quality of life. The natural history of DCM is poorly understood. This is a preliminary report of the first 60 patients recruited to the MYelopathy NAtural History (MYNAH) Registry.

Functional alignment minimizes changes to joint line obliquity in robotic-assisted total knee arthroplasty: a CT analysis of functional versus kinematic alignment in 2,116 knees using the Coronal Plane Alignment of the Knee (CPAK) classification.

Aims: Functional alignment (FA) in total knee arthroplasty (TKA) aims to achieve balanced gaps by adjusting implant positioning while minimizing changes to constitutional joint line obliquity (JLO). Although FA uses kinematic alignment (KA) as a starting point, the final implant positions can vary significantly between these two approaches. This study used the Coronal Plane Alignment of the Knee (CPAK) classification to compare differences between KA and final FA positions.

Intrafascial Colpotomy, Edge-to-Edge Closure, and Peritoneal Graft Technique for Minimizing Mesh Erosion in Concurrent Robotic Hysterectomy and Sacrocolpopexy.

Introduction And Hypothesis: Sacrocolpopexy (SCP) is a recognized treatment for apical pelvic organ prolapse (POP). However, mesh erosion remains a concern, particularly when performed with concomitant hysterectomy. This video presents data on one case of a modified technique aimed at potentially minimizing mesh erosion in robotic SCP.

Considerations of morphometry and phenotypes in modern knee arthroplasty.

As advancements in total knee arthroplasty progress at an exciting pace, two areas are of special interest, as they directly impact implant design and surgical decision making. Knee morphometry considers the three-dimensional shape of the articulating surfaces within the knee joint, and knee phenotyping provides the ability to categorize alignment into practical groupings that can be used in both clinical and research settings. This annotation discusses the details of these concepts, and the ways in which they are helping us better understand the individual subtleties of each patient's knee.

Four-Dimensional Flow MRI for Cardiovascular Evaluation (4DCarE): A Prospective Non-Inferiority Study of a Rapid Cardiac MRI Exam: Study Protocol and Pilot Analysis.

Background: Accurate measurements of flow and ventricular volume and function are critical for clinical decision-making in cardiovascular medicine. Cardiac magnetic resonance (CMR) is the current gold standard for ventricular functional evaluation but is relatively expensive and time-consuming, thus limiting the scale of clinical applications. New volumetric acquisition techniques, such as four-dimensional flow (4D-flow) and three-dimensional volumetric cine (3D-cine) MRI, could potentially reduce acquisition time without loss in accuracy; however, this has not been formally tested on a large scale.

Online radiology teaching for doctors in a university setting: an Australian experience.

Background: Imaging Surgical Patients (ISP) and Essential Imaging for Clinicians (EIC) are online medical imaging units of study for non-radiologist medical practitioners within the Master of Surgery and Master of Medicine programs at the University of Sydney. This paper presents the findings of evaluations of the coursework associated with these units.

Methods: ISP and EIC were reviewed after successful delivery of 8 and 4 semesters, respectively.

Single-use synthetic plastic and natural fibre anaesthetic drug trays: a comparative life cycle assessment of environmental impacts.

Background: Single-use anaesthetic drug trays are used widely in Australia, but their environmental impact is unclear.

Methods: A life cycle assessment was completed for 10 different types of single-use anaesthetic drug trays made of four materials: the synthetic plastics polypropylene and polystyrene, and the natural fibres bagasse (sugarcane pulp) and cellulose pulp.

Results: Carbon emissions per tray from total life cycle with landfill disposal were 33-454 g CO-eq, which equates to 152-2066 tonnes CO-eq annually.

How often do we alter constitutional limb alignment, joint line obliquity, and Coronal Plane Alignment of the Knee (CPAK) phenotype when performing mechanically aligned TKA?

Aims: While mechanical alignment (MA) is the traditional technique in total knee arthroplasty (TKA), its potential for altering constitutional alignment remains poorly understood. This study aimed to quantify unintentional changes to constitutional coronal alignment and joint line obliquity (JLO) resulting from MA.

Methods: A retrospective cohort study was undertaken of 700 primary MA TKAs (643 patients) performed between 2014 and 2017.

A case of life-threatening, early postoperative refeeding syndrome in an obese young female undergoing laparoscopic sleeve gastrectomy.

Early complications after a laparoscopic sleeve gastrectomy (LSG) include bleeding, leaks, strictures and bowel obstructions. Patients post-LSG experience rapid but intended weight loss and may be on a restricted diet before and following surgery. Thus, many of these patients are in a malnourished state, placing them at a risk of developing potentially life-threatening refeeding syndrome (RFS).

What are the risks associated with lipiodol hysterosalpingography? A literature review.

Introduction: Hysterosalpingography is widely used as a first-line investigation for infertility, and may also be therapeutic, increasing pregnancy rates. Aqueous and oil-based contrast agents can be used. Some studies suggest Lipiodol hysterosalpingography has a greater therapeutic effect on fertility than aqueous contrast, though this is contentious.

Increased Bone Formation and Accelerated Bone Mass Accrual in a Man Presenting with Diffuse Osteosclerosis/High Bone Mass Phenotype and Adenocarcinoma of Unknown Primary.

A 71-year-old man was referred for evaluation of incidental generalized osteosclerosis. He was found to have a high bone mass (HBM) with an elevated lumbar spine bone mineral density (BMD) Z-score of +5.3.

Is it time to drop royal patronage of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists?

Historically there is a strong, amiable and mutually respectful relationship between Australian and New Zealand obstetricians and gynaecologists (O&Gs) and the British O&G establishment represented by the Royal College of Obstetricians and Gynaecologists (RCOG). The 'Royal' prefix pays homage to this relationship. With the evolution of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG), there have been suggestions that the Royal prefix no longer accurately reflects the raison d'être and aspirations of RANZCOG.

Long leg radiographs underestimate the degree of constitutional varus limb alignment and joint line obliquity in comparison with computed tomography: a radiographic study.

Purpose: The purpose of this study was to understand if differences exist between computed tomography (CT) and long leg radiographs (LLR) when defining coronal plane alignment of the lower limb in total knee arthroplasty (TKA). It aimed to identify any such differences between the two imaging modalities by quantifying constitutional limb alignment (arithmetic hip-knee-ankle angle (aHKA), joint line obliquity (JLO) and Coronal Plane Alignment of the Knee (CPAK) type within the same population.

Methods: A retrospective radiographic study compared pre-operative LLR and CT measurements in patients undergoing robotic-assisted TKA.

Barriers to progression through Australian obesity management pathways: Survey data from the ACTION-IO study.

Background And Objectives: Our previous work uncovered a nine-year delay, from when Australian people with obesity (PwO) first began struggling with excess weight and first discussed weight with a healthcare professional (HCP). In this study we explore barriers to having an obesity consultation, making and discussing the diagnosis of obesity and arranging a management plan, including a follow-up appointment.

Method: Australian PwO (n = 1000) and HCPs (n = 200; 50% general practitioners [GPs]), completed the Awareness, Care & Treatment In Obesity Management - An International Observation (ACTION-IO) online survey.

The Safety and Effects of Pregnancy after Abdominoplasty: A Systematic Review of the Literature.

Background: As advanced maternal age and bariatric procedures have become more common, the number of women seeking pregnancy after having abdominoplasty has increased. This has traditionally been a relative contraindication and counselled against, though there are little data in the literature regarding the potential effects to mother and baby.

Methods: A systematic review of Medline and Embase databases was performed to identify cases of pregnancy occurring after abdominoplasty.

Global Impact of Obesity.

The prevalence of preobesity and obesity is rising globally, multiple epidemiologic studies have identified preobesity and obesity as predisposing factors to a number of noncommunicable diseases including type 2 diabetes (T2DM), cardiovascular disease (CVD), and cancer. In this review, we discuss the epidemiology of obesity in both children and adults in different regions of the world. We also explore the impact of obesity as a disease not only on physical and mental health but also its economic impact.
