Background And Purpose: Adults living with Cerebral Palsy (CP) who are non-ambulatory are at increased risk for falls, contractures, reduced bone density, and pain. There is limited evidence for core strength training, anterior chain activation exercises, or high intensity gait training (HIGT) to improve gait function in adults with CP. The purpose of this case report is to describe the use of anterior chain muscle activation and HIGT to improve walking in a non-ambulatory adult male with quadriplegic CP.

Adult Myopia Progression.

Invest Ophthalmol Vis Sci

November 2024

Purpose: To explore evidence for myopic shift between the ages of 20 and 50 years.

Methods: Three usable sets of data with long-term adult refractive progression were identified: (1) US population-based prevalence data for those 18 to 24 years of age in 1971 and 1972 and 45 to 54 years of age from 1999 to 2004; a logit transformation of prevalence values at different refractive error thresholds allowed estimation of myopic progression in this group. (2) German clinical data describing 5- to 10-year progression for different refractive error groupings across 5-year age bands from 20 to 49 years; these were extracted, adjusted, and analyzed.

The oral contraceptive pill (OCP) is widely used by women worldwide, yet the influence of the OCP on carbohydrate metabolism remains under-investigated, with existing studies being few and largely cross-sectional. The study objective was to assess, for the first time, the effect of the combined OCP on postprandial glycaemic response to an oral glucose bolus, using a randomised crossover design. The effect of a combined monophasic OCP phase on glucose homeostasis and metabolic profile was investigated in 21 healthy young women, who were regular users of either androgenic or anti-androgenic OCP formulations.

Purpose: When myopia control treatment is discontinued, progression will increase, but does it revert to expected values based on the age and race of the child or does it accelerate further? The latter scenario is considered a rebound.

Methods: A PubMed search was conducted with the words 'rebound' and 'myopia control', identifying further papers from reviews. Inclusion was limited to prospective studies with ≥6 months of treatment, ≥3 months of data following cessation and with axial length data, which allowed calculation of rebound.

Article Synopsis
  • The study explores the relationship between the prevalence of high myopia and myopia, noting that as overall myopia rates increase, high myopia rates rise at a faster rate.
  • It uses data from 41 datasets to model how changes in myopia prevalence impact the prevalence of high myopia, demonstrating that the ratio of increase varies with overall myopia rates.
  • The findings suggest that while interventions may effectively influence high myopia prevalence, strategies aimed at delaying the onset of myopia will be more impactful for both conditions.

Article Synopsis
  • The study focuses on understanding how axial elongation, a key factor in the progression of primary myopia in children, is affected by various factors through a meta-regression analysis.
  • Researchers conducted a systematic search of multiple databases, analyzing data from 64 studies to model the mean rate of axial elongation in low to moderate myopia cases.
  • Results revealed that axial elongation is significantly greater in Asian children compared to non-Asians, with both groups showing a consistent decline in elongation rates as they age, highlighting the complexity of managing myopia in individual children.

  • - This study explores how obsessive-compulsive disorder (OCD) affects family functioning from the perspectives of affected children, their siblings, and parents, highlighting the often-overlooked views of siblings.
  • - Researchers analyzed data from 185 families, finding that parents reported the most significant impact of OCD, followed by the affected children and then the siblings, with factors such as family accommodation and blame playing key roles in dysfunction.
  • - While the study sheds light on the dynamics of family life affected by pediatric OCD, its cross-sectional nature and missing data limit causal conclusions, emphasizing the need for clinicians to consider all family members' experiences in treatment approaches.

The emergence of next generation sequencing and widespread use of mutational profiling in acute myeloid leukemia (AML) has broadened our understanding of the heterogeneous molecular basis of the disease. Since genetic sequencing has become a standard practice, several driver mutations have been identified. Accordingly, novel targeted therapeutic agents have been developed and are now approved for the treatment of subsets of patients that carry mutations in FLT3, IDH1, and IDH2 [1, 2].

The risk of eye diseases such as myopic macular degeneration increases with the level of myopia, but there is no safe level of myopia and the burden of lower degrees of myopia remains considerable. Effective treatments are available that slow progression and thus limit the final degree of myopia. In this review, the rationale for slowing progression is summarized, and a case made for treating all myopic children.
