Longitudinal integrated clerkships (LICs) have been adopted by medical schools to overcome the limitations of traditional block clerkship rotations and to promote continuity of care. In 2018, Seoul National University College of Medicine introduced a patient-centered LIC program as part of a new curriculum in parallel with traditional block rotation clerkships. The purpose of this study was to present the patient-centered LIC program and to investigate its educational effects.

In 2018 and 2019, a total of 298 third-year medical students participated in the LIC program. We divided the students into groups of eight, which were organized into corresponding discussion classes. Throughout the academic year, students followed up patients by interviewing them at the hospital or reviewing their electric medical records. Discussion classes on set topics were held seven times per year with facilitators and clinical faculites. Students completed a course evaluation questionnaire at the end of the academic year.

Trauma mortality review is the first step in assessing the quality of the trauma treatment system and provides an important basis for establishing a regional inclusive trauma system. This study aimed to obtain a reliable measure of the preventable trauma death rate in a single province in Korea.

From January to December 2017, a total of 500 sample cases of trauma-related deaths from 64 hospitals in Gyeonggi Province were included. All cases were evaluated for preventability and opportunities for improvement using a multidisciplinary panel review approach.

Overall, 337 cases were included in the calculation for the preventable trauma death rate. The preventable trauma death rate was estimated at 17.0%. The odds ratio was 3.97 folds higher for those who arrived within "1-3 hours" than those who arrived within "1 hour." When the final treatment institution was not a regional trauma center, the odds ratio was 2.39 folds higher than that of a regional trauma center. The most significant stage of preventable trauma death was the hospital stage, during which 86.7% of the cases occurred, of which only 10.3% occurred in the regional trauma center, whereas preventable trauma death was more of a problem at emergency medical institutions.

The preventable trauma death rate was slightly lower in this study than in previous studies, although several problems were noted during inter-hospital transfer; in the hospital stage, more problems were noted at emergency medical care facilities than at regional trauma centers. Further, several opportunities for improvements were discovered regarding bleeding control.

The human 8-oxoguanine DNA glycosylase 1 (hOGG1) gene encodes a DNA glycosylase that removes 8-hydroxy-2-deoxyguanine (8-OH-dG) DNA damage to protect against gene mutations. The association of hOGG1 Ser326Cys polymorphism with lung cancer risk has predicted that hOGG1-Cys variants are less effective at removing 8-OH-dG damage from DNA; therefore, these variants might show an increased occurrence of tumor suppressor gene and oncogene mutations. However, no evidence has yet supported this hypothesis.

Direct sequencing was performed to examine the mutations of p53 and EGFR genes in lung tumors from patients with non-small cell lung cancer (NSCLC). Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to examine hOGG1 Ser326Cys polymorphism in this study population.

A total of 99 p53-mutated and 99 EGFR-mutated patients with NSCLC were selected to explore the possible associations of these mutations with hOGG1 Ser326Cys polymorphism. The p53-mutated and EGFR-mutated patientsutations and these patients who were treated with gefitinib or erlotinib could be a higher risk to occur EGFR T790M mutation.
NSCLC patients with hOGG1-Cys variants might be helpful to predict patients having higher risk of EGFR exon 19 deletion mutations and these patients who were treated with gefitinib or erlotinib could be a higher risk to occur EGFR T790M mutation.Percutaneous thermal ablation is an important treatment for lung cancer and is widely used in hospitals. Puncture biopsy is generally required for pathological diagnosis before or after thermal ablation. Pathological diagnosis provides both evidence of benign and malignant lesions for ablation therapy and is of important significance for the next step in disease management. Furthermore, the sequence of ablation and biopsy affects the accuracy of pathological diagnosis, the complete ablation rate of thermal ablation, and incidence of surgery-related complications. Ultimately, it may affect the patient's benefit from local treatment. This article reviews the research progress of traditional asynchronous biopsy followed by ablation, the emerging methods of synchronous biopsy followed by ablation, and synchronous ablation followed by biopsy in the last decade. KEY POINTS The sequence of ablation and biopsy affects the accuracy of pathological diagnosis, the complete ablation rate of thermal ablation, and the incidence of surgical-related complications. This article reviewed the recent 10 years' literature on the surgical sequence of biopsy and ablation for lung tumors, the advantages, disadvantages and indications of different orders were analyzed.
We investigated the rate of employment in patients with functional seizures (FS) in a follow-up study. We also investigated the rate of receiving disability benefits in these patients. read more Finally, we investigated factors that are potentially associated with their employment status.

In this long-term study, all patients with FS, who were diagnosed at Shiraz Comprehensive Epilepsy Center, Iran, from 2008 to 2018, were investigated. In a phone call interview to the patients in February 2020, we tried to obtain the following information seizure outcome, employment status, receiving disability benefits, and their current drug regimen, if any. The first call was made in the evening and after working hours. In case of no response, we made two more attempts in the following weeks to contact the patients during different time periods of the day.

Eighty- four patients participated. Thirty-one patients (37%) were employed, and 53 people (63%) were not; at the first visit, the rate of employment was 23%. Female sex (Odds Ratio [OR] 12.18; 95% Confidence Interval [CI] 3.51-42.18; p=.0001), taking psychiatric drugs (OR 4.93; 95% CI 1.17-20.73; p=.02), and being employed previously (OR 0.19; 95% CI 0.04-0.77; p=.02) were independently significantly associated with the current employment status. Three patients (4%) reported receiving disability social benefits, two women and one man.

This study highlights that unemployment is a serious issue in patients with FS and psychiatric comorbidities play a significant role in the employment status in these patients.

Long noncoding RNA maternally expressed gene 3 (MEG3) expression was significantly decreased in acute myeloid leukemia (AML). However, its expression and clinical significance in acute promyelocytic leukemia (APL) remain unclear. Thus, the present study aimed to investigate the expression of MEG3 in APL and explore its clinical value.

A total of 287 AML patients derived from The Cancer Genome Atlas (TCGA) and Vizome database were enrolled. A development and validation cohort, including APL, AML with AML1/ETO, and other types of AML patients and disease controls, from the First Affiliated Hospital of Nanchang University, were also enrolled in this study. The correlation between MEG3 expression and the clinicopathological features in APL was investigated. The diagnostic values of MEG3 expression in APL were analyzed by receiver operating characteristic (ROC) curves.

In the development set, MEG3 expression was significantly increased in APL than AML with AML1/ETO, other types of AML, and disease controls, which was consistent with the results from the database analysis. MEG3 expression in APL was associated with age (P=.0053) but did not correlate with other clinicopathological features (P>.05). ROC curve analysis in the development set and diagnostic test analysis in the validation set suggested that MEG3 expression has a significant value in the diagnosis of APL. Furthermore, the expression of MEG3 decreased during the follow-up of patients with negative PML/RARα fusion gene.

MEG3 serves as a novel marker for the diagnosis of APL, evaluates the curative effect, and provides a novel direction for further research.

RNA-sequencing-based classifiers can stratify pancreatic ductal adenocarcinoma (PDAC) into prognostically significant subgroups but are not practical for use in clinical workflows. Here, we assess whether histomorphological features may be used as surrogate markers for predicting molecular subgroup and overall survival in PDAC.

Ninety-six tissue samples from 50 patients with non-resectable PDAC were scored for gland formation, stromal maturity, mucin, necrosis, and neutrophil infiltration. Prognostic PDAC gene expression classifiers were run on all tumors using whole transcriptome sequencing data from the POG trial (NCT02155621). Findings were validated using digital TCGA slides (n=50). Survival analysis used multivariate Cox proportional-hazards tests and log-rank tests.

The combination of low gland formation and low neutrophil infiltration was significantly associated with the poor prognosis PDAC molecular subgroup (basal-like or squamous) and was an independent predictor of shorter overall survival, in both frozen section (n=47) and formalin-fixed paraffin-embedded (n=49) tissue samples from POG patients, and in the TCGA samples. This finding held true in the subgroup analysis of primary (n=17) and metastatic samples (n=79). The combination of high gland formation and high neutrophils had low sensitivity but high specificity for favorable prognosis subgroups.

The assessment of gland formation and neutrophil infiltration on routine histological sections can aid in prognostication and allow inferences to be made about molecular subtype, which may help guide patient management decisions and contribute to our understanding of heterogeneity in treatment response.
