Plast Reconstr Surg Glob Open

August 2024

From the Department of Plastic and Reconstructive Surgery, iWELL Plastic Surgery Clinic, Seoul, South Korea.

Article Synopsis
  • Zygomatic bone overdevelopment can make the face look squarer, leading many to seek zygoma reduction surgery for a more oval facial shape, but this procedure can cause cheek tissue sagging.
  • This study utilized artificial intelligence (AI) to objectively assess soft-tissue changes in patients after zygoma reduction surgery, using methods such as tracking facial landmarks and analyzing changes in facial curvature.
  • The findings indicated no significant differences in cheek sagging before and after surgery, suggesting that AI could provide valuable objective evaluations in the field and potentially lead to advancements in predicting soft-tissue changes pre-surgery.

Article Synopsis
  • A novel ctDNA testing method shows potential for improving prognosis and treatment monitoring in diffuse large B-cell lymphoma (DLBCL) patients.
  • In a study of 50 DLBCL patients, ctDNA was detected in 95% pre-treatment, and higher baseline levels were linked to poorer outcomes, while clearance during treatment predicted better responses.
  • Overall, ctDNA clearance was a strong predictor of favorable patient outcomes and could lead to earlier detection of treatment responses compared to traditional imaging methods.

Background: Prepubertal transgender, nonbinary, and gender-diverse (TGD) children (ie, those asserting gender identity, expressing gender-role behavior outside of culturally defined norms for their sex registered at birth, or both) are presenting in greater numbers to pediatric gender clinics across the United States and abroad. A large subset of TGD children experiences gender dysphoria, that is, distress that arises from the incongruence between gender identity and sex registered at birth. A lack of consensus exists regarding care for prepubertal TGD children due, in part, to a dearth of empirical research on longitudinal developmental trajectories of gender identity, role behavior, and gender dysphoria (when present).

Article Synopsis
  • The study aimed to explore vaccination knowledge and barriers among minority adults, using a cross-sectional survey conducted in otolaryngology clinics and a cancer screening event.
  • Findings revealed low rates of HPV vaccination among both minority (17.67%) and their children (33.55%), with minorities displaying significantly lower knowledge about HPV and its link to cervical and head and neck cancers.
  • The primary reason minorities were not vaccinated was lack of knowledge about the HPV vaccine, suggesting that educational interventions could improve vaccination rates in this demographic.

Article Synopsis
  • The 2022 European LeukemiaNet (ELN) classification predicts outcomes for younger acute myeloid leukemia (AML) patients but was tested for those aged 60 and older receiving lower-intensity treatment (LIT), involving 595 patients with varying risk levels.
  • Results showed that while ELN risk is predictive of overall survival, it fails to distinguish between favorable and intermediate risks, prompting further exploration into adverse-risk patients' molecular abnormalities.
  • A new "Beat-AML" risk classification was developed, combining favorable and intermediate risks and integrating mutation scoring, leading to better survival predictions for older AML patients and aiding treatment decisions with clear risk group delineations.

Brain rhythms provide the timing for recruitment of brain activity required for linking together neuronal ensembles engaged in specific tasks. The γ-oscillations (30 to 120 Hz) orchestrate neuronal circuits underlying cognitive processes and working memory. These oscillations are reduced in numerous neurological and psychiatric disorders, including early cognitive decline in Alzheimer's disease (AD).

Bruck syndrome is an autosomal recessive form of osteogenesis imperfecta caused by biallelic variants in PLOD2 or FKBP10 and is characterized by joint contractures, bone fragility, short stature, and scoliosis. PLOD2 encodes LH2, which hydroxylates type I collagen telopeptide lysines, a critical step for collagen crosslinking. The Plod2 global knockout mouse model is limited by early embryonic lethality, and thus, the role of PLOD2 in skeletogenesis is not well understood.

Article Synopsis
  • The study examined the impact of two medications, sacubitril/valsartan and ramipril, on short-term kidney function changes in patients experiencing acute myocardial infarction (MI), focusing on serum creatinine levels.
  • In a trial with 5,661 patients, it was found that those taking sacubitril/valsartan had a slightly higher likelihood of experiencing initial increases in serum creatinine compared to those taking ramipril.
  • However, acute changes in creatinine levels from either medication did not correlate with worse long-term cardiovascular outcomes or significant changes in kidney function, suggesting the initial increases might not indicate long-term risks.

Transition services-programs that support adolescents and young adults (AYAs) as they move from a child-centered to a more autonomous, adult-orientated healthcare system-have been associated with improved short- and long-term healthcare outcomes. Unfortunately, there is a paucity of evidence exploring transition services within the neurogastroenterology and motility (NGM) field. The overall aim of this article, endorsed by the American Neurogastroenterology and Motility Society and European Society of Neurogastroenterology and Motility, is to promote a discussion about the role of transition services for patients with NGM disorders.

Background: Apart from the well-established skeletal effects, itamin D has been explored as a secretagogue influencing various adipokines, including adiponectin and irisin. Recent evidence suggests that specific forms of 25-Hydroxyvitamin D (25(OHD), such as free and bioavailable 25(OH)D, may provide more accurate measurements of vitamin D status. The relationship between vitamin D status and serum irisin and adiponectin concentrations remains largely unexplored, particularly during pregnancy.
