Specific interventions could improve sarcopenic obesity, but overall significance is limited by scarcity of data and lack of uniformity in the definition of sarcopenic obesity itself. Further research should clarify optimal treatment options for sarcopenic obesity in age classes other than the geriatric population.

Chronic kidney disease (CKD) is highly prevalent in elderly patients. There is growing recognition of the importance of attention to dietary protein intake (DPI) in this population given their predisposition to age-related changes in kidney function and coexisting comorbidities (i.e., hypertension). We reviewed the impact of DPI on kidney health and survival and the role of dietary protein management in older CKD patients.
While kidney function parameters including glomerular filtration rate (GFR) and renal plasma flow are slightly lower in elderly patients irrespective of CKD status, the kidneys' ability to compensate for increased DPI by augmentation of GFR is preserved until 80 years of age or less. However, long-term consumption of high DPI in individuals of older age and/or with CKD may contribute to kidney function deterioration over time. Prescription of a plant-dominant low-protein diet of 0.6-0.8 g/kg/day with more than 50% from plant sources or very low protein diets less than 0.45 g/kg/day supplemented with essential amino acids or their keto-analogues may be effective in preserving kidney function in older patients and their younger counterparts, while also monitoring for development of protein-energy wasting (PEW).
Using tailored precision nutrition approaches in prescribing plant-dominant low DPI that also maintains adequate energy and nitrogen balance may ameliorate kidney function decline while also preventing development of PEW in elderly patients with CKD.

In early 2019, the Global Leadership Initiative on Malnutrition (GLIM) concept was published advocating a two-step procedure, that is, screening followed by confirmation of the malnutrition diagnosis requiring a combination of phenotypic and etiologic criteria. This review summarizes 14 publications that have applied the GLIM criteria in older populations.
Four studies miss data on muscle mass. The mandatory screening appears missing in some studies. Two studies report that criterion validity is fair to good when compared with Subjective Global Assessment as semigold standard. Most studies report strong predictive validity when mortality is used as outcome. Not unexpectedly malnutrition relates strongly to sarcopenia as low muscle mass is a GLIM criterion. Overall, the lack of guidance on how to assess muscle mass and disease burden/inflammation in the original GLIM publication provides uncertainties on how to interpret the results.
Fourteen exclusively retrospective studies in older adult cohorts are summarized. In several cases, the data sets are imperfect or incomplete. Still, criterion and predictive validity for GLIM appears well acceptable when applied for older adults. find more Continuing global implementation efforts are justified. The GLIM consortium needs to provide guidance on assessment of muscle mass and disease burden/inflammation. Moreover, further prospective validation studies are needed to add knowledge for the future GLIM format updates.

It has been a game changer in how we manage keratoconus. Early diagnosis and treatment is essential in paediatric patients as younger patients progress more rapidly and have poorer transplant outcomes. There is an ongoing debate around standard, accelerated, and transepithelial protocols of CXL, the role of CXL, and the combination of laser refractive surgery. Future developments will improve CXL safety and efficacy and the scope of utilization, but we must be careful not to leap too far ahead with clinical applications before publication of basic science research and good clinical results with standardized protocols.Before the advent of modern tomographic imaging and corneal cross-linking (CXL), diagnosis and treatment of ectatic disease were limited to disease severity where changes on the anterior corneal surface lead to visual complaints. Rigid contact lenses and/or penetrating keratoplasty addressed late stage disease, as identifying early or subclinical disease was not possible, or its need appreciated. The emergence of CXL as a viable treatment to alter the natural progression of keratoconus heightened the need for improved diagnostics.Several methods have been described in the literature to evaluate and document progression in keratoconus, but there has been no consistent definition of ectasia progression. Newer imaging techniques (ie, tomography) allowed the detection of earlier ectatic disease, before visual loss and subjective complaints. The Belin ABCD classification/staging system was introduced on a Scheimpflug imaging system [Pentacam, (Oculus GmbH, Wetzlar, Germany)] to address previous shortcomings. The ABCD system utilizes 4 parameters Anterior ("A") and posterior ("B" for Back) radius of curvature taken from a 3.
