Sci Rep

June 2024

Division of Hematology-Oncology, Department of Medicine, Samsung Medical Center, Sungkyunkwan University School of Medicine, 81 Irwon-ro, Gangnam-gu, Seoul, 06351, Republic of Korea.

Article Synopsis
  • Lazertinib, a third-generation EGFR-tyrosine kinase inhibitor, was analyzed for its effectiveness in treating advanced EGFR T790M-positive non-small-cell lung cancer compared to osimertinib.
  • The study involved 75 patients on lazertinib and 110 on osimertinib, but after matching for baseline characteristics, each group was reduced to 60 patients for fair comparison.
  • Results showed that lazertinib had an objective response rate of 76.7% and a median progression-free survival of 12.3 months, which are similar to osimertinib but with the potential for better overall survival benefits.

Article Synopsis
  • Occult lymph node metastasis (OLNM) is common in patients with resectable non-small cell lung cancer (NSCLC), despite following established diagnostic guidelines.
  • The study evaluated the risk of OLNM based on specific radiologic characteristics of primary tumors as seen on CT scans in a retrospective analysis of 2042 NSCLC patients.
  • Findings revealed that certain tumor features, such as endobronchial location, significantly increased the risk of OLNM, while others, like heterogeneous ground-glass opacity, had a lower risk, helping clinicians better determine the need for invasive nodal staging.

Article Synopsis
  • A study analyzed the impact of an antimicrobial stewardship program (ASP) on pediatric patients' bacteremia, antimicrobial use, and mortality rates between 2001 and 2019.
  • The results showed a significant increase in the proportion of ESBL-producing bacteria from 17% to 35% after the ASP was implemented, but overall antimicrobial use decreased.
  • Importantly, the 30-day mortality rate for patients with bacteremia remained stable at 10% in both pre- and post-intervention periods, indicating that the ASP was effective in reducing medication usage without increasing death rates.

Article Synopsis
  • The study investigates the relationship between phenotypically diverse subtypes of bipolar disorder (BD) and genetic factors, suggesting that different subtypes may share a genetic basis with other psychiatric disorders.* -
  • Researchers analyzed six specific "lifetime phenotype dimensions" of BD and their associations with polygenic risk scores (PRS) derived from various populations, revealing distinct patterns for each dimension.* -
  • The findings support the idea of genetic diversity in BD and indicate shared genetic risks with other mental illnesses, highlighting the need for more detailed research across different populations to understand these relationships better.*

This meta-analysis evaluates the efficacy and safety of chimeric antigen receptor (CAR) T-cell therapy and bispecific antibodies for relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL). We searched MEDLINE, Embase, and Cochrane databases until July 2023 for trials assessing CAR T-cell therapies and CD20×CD3 bispecific antibodies as third or subsequent lines in R/R DLBCL. Random-effects models estimated the complete response (CR) rate and secondary outcomes, with meta-regressions adjusting for relevant covariates.

BMC Med

May 2024

Division of Endocrinology and Metabolism, Department of Medicine, Samsung Medical Center, Sungkyunkwan University School of Medicine, 81, Irwon-Ro, Gangnam-Gu, Seoul, 06351, Republic of Korea.

Background: We investigated the effects of a physical activity encouragement intervention based on a smartphone personal health record (PHR) application (app) on step count increases, glycemic control, and body weight in patients with type 2 diabetes (T2D).

Methods: In this 12-week, single-center, randomized controlled, 12-week extension study, patients with T2D who were overweight or obese were randomized using ratio 1:2 to a group using a smartphone PHR app (control group) or group using the app and received individualized motivational text messages (intervention group) for 12 weeks. During the extension period, the sending of the encouraging text messages to the intervention group was discontinued.

Stroke-caused synergies may result from the preferential use of the reticulospinal tract (RST) due to damage to the corticospinal tract. The RST branches multiple motoneuron pools across the arm together resulting in gross motor control or abnormal synergies, and accordingly, the controllability of individual muscles decreases. However, it is not clear whether muscles involuntarily activated by abnormal synergy vary depending on the muscles voluntarily activated when motor commands descend through the RST.

Recently, the pathomechanisms of keloids have been extensively researched using transcriptomic analysis, but most studies did not consider the activity of keloids. We aimed to profile the transcriptomics of keloids according to their clinical activity and location within the keloid lesion, compared with normal and mature scars. Tissue samples were collected (keloid based on its activity (active and inactive), mature scar from keloid patients and normal scar (NS) from non-keloid patients).

Article Synopsis
  • Manganese porphyrins, particularly MnTnBuOE-2-PyP (BMX-001), show enhanced effects when used with radiotherapy, but the exact immune mechanisms involved are not fully understood.
  • In a study with mice bearing 4T1 tumors, it was found that using MnBuOE alongside radiotherapy led to a significant reduction in cancer-associated fibroblasts and altered interactions between various immune cells.
  • The combination treatment (MnBuOE/RT) resulted in increased maturation markers in dendritic cells and more M1 macrophages, showing promise for better immunomodulation compared to radiotherapy alone.

Large-scale cross-ancestry genome-wide meta-analysis of serum urate.

Nat Commun

April 2024

Department of Digital Health, Samsung Advanced Institute for Health Sciences and Technology (SAIHST), Sungkyunkwan University, Samsung Medical Center, Seoul, Republic of Korea.

Hyperuricemia is an essential causal risk factor for gout and is associated with cardiometabolic diseases. Given the limited contribution of East Asian ancestry to genome-wide association studies of serum urate, the genetic architecture of serum urate requires exploration. A large-scale cross-ancestry genome-wide association meta-analysis of 1,029,323 individuals and ancestry-specific meta-analysis identifies a total of 351 loci, including 17 previously unreported loci.

  • The study aimed to explore the link between body composition and breast cancer risk in premenopausal women, using data from the Kangbuk Samsung Cohort Study involving 125,188 participants.
  • Over an average follow-up of 6.7 years, 1,110 cases of breast cancer were identified, showing that higher body mass index (BMI) and waist circumference correlated with a lower risk of breast cancer.
  • Interestingly, while a higher fat mass to weight ratio was associated with reduced breast cancer risk, a higher muscle mass to weight ratio was linked to increased risk, suggesting a complex relationship between body composition and breast cancer outcomes.

Association between genetic risk and adherence to healthy lifestyle for developing age-related hearing loss.

BMC Med

March 2024

Department of Biostatistics, Epidemiology and Informatics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, USA.

Background: Previous studies have shown that lifestyle/environmental factors could accelerate the development of age-related hearing loss (ARHL). However, there has not yet been a study investigating the joint association among genetics, lifestyle/environmental factors, and adherence to healthy lifestyle for risk of ARHL. We aimed to assess the association between ARHL genetic variants, lifestyle/environmental factors, and adherence to healthy lifestyle as pertains to risk of ARHL.
