PURPOSE: Rheumatoid arthritis (RA) is a common, chronic inflammatory arthritis that develops most often in women. Gonadal hormones may account for the sexual dimorphism in the immune response and for the greater incidence of autoimmune disease in females. Gonadotrophin-releasing hormone (GnRH), one of the gonadal hormones, plays an important role in immune system modulation. This study examined the effects of single nucleotide polymorphisms (SNP) in GnRH on gender differences in the pathophysiology of RA. MATERIALS AND METHODS: The presence of SNPs rs2659590, rs2321248, rs6186, rs6185, and rs2321049 in the human GnRH1 gene was confirmed in Korean RA patients by Taqman(R) SNP genotyping assays. A total of 153 unrelated female, Korean RA patients and 96 female Korean controls participated. RESULTS: There were no significant associations between GnRH1 polymorphisms and RA. However, we found that the rs2659590, rs6185 and rs2321248 polymorphism might be associated with a susceptibility to aberrantly high erythrocyte sedimentation rates in female RA patients. CONCLUSION: Additional studies, with a larger number of patients and in different populations will be required to assess whether GnRH1 polymorphisms and these haplotypes could be used as susceptibility or resistance markers in RA. To our knowledge, this study is the first to analyze associations between SNPs of GnRH1 and RA.

BACKGROUND: Both human leukocyte antigen (HLA) class I and programmed death-ligand 1 (PD-L1) molecules are known to play important roles in cancer immunity. In this study, we evaluated HLA class I expression in resected adenocarcinoma of the lung, and investigated its prognostic impact in correlation with PD-L1 expression. METHODS: HLA class I and PD-L1 expression was evaluated by immunohistochemistry in a total of 403 resected lung adenocarcinomas using tissue microarray. Correlations between the expression of HLA class I/PD-L1 and clinicopathologic features and prognostic significance were analyzed. RESULTS: HLA class I expression was reduced in 91.6% of adenocarcinoma, and more frequently reduced in patients with younger age, absence of vascular invasion, and low pathologic stage (p = .033, p = .007, and p = .012, respectively). Positive PD-L1 expression in tumor cells was 16.1% (1% cut-off), and associated with poor differentiation, presence of vascular invasion and nodal metastasis (p < .001, p = .002, and p = .032, respectively). On survival analysis, HLA class I or PD-L1 expression alone did not show any statistical significance. On the integrated analysis, HLA class I (+)/PD-L1 (+) subgroup showed a significantly shorter overall survival than other groups (p = .001). Multivariate analysis revealed that coexpression of HLA class I and PD-L1 was an independent poor prognostic factor of lung adenocarcinoma. (p < .001; hazard ratio, 6.106; 95% confidence interval, 2.260 to 16.501). CONCLUSIONS: Lung adenocarcinoma with coexpression of HLA class I and PD-L1 was associated with poor prognosis. This subgroup may evade immune attack by expressing PD-L1 protein despite HLA expression.

Viral infections can be causative in many glomerular disease, and human immunodeficiency virus (HIV) infection is closely related to a collapsing focal segmental glomerulosclerosis (FSGS). This is known as HIV associated nephropathy (HIVAN) and is characterized clinically by proteinuria, often of sudden onset, with rapidly progressive renal dysfunction resulting in end stage renal disease (ESRD) over several months. Increasingly, other primary renal diseases are being described in HIV infected patients, including IgA nephropathy, an immune complex lupus-like neprhopathy, and tubulonephritis. We observed rare HIVAN case presenting membranous glomerulonephritis with nephrotic syndrome in a woman who was positive for HIV without hepatitis B viral infection. She was treated with Methylprednisolone 60 mg/day, zidovudine 600 mg/day, efavirenz 60 mg/day, and lamivudine 300 mg/day for 5 months. After treatment, proteinuria decreased from 4,092 mg/day to 419 mg/day and CD4 T cell count rose from 594/mL to 1,176/mL. The effectiveness and safety of corticosteroids in the treatment of HIVAN remained controversial but this case showed good response for steroid with triple antiviral therapy about HIVAN especially membranous glomerulonephritis.

Background:
Activating mutations in the tyrosine kinase domain of epidermal growth factor receptor (EGFR) are predictive biomarkers for response to EGFR–tyrosine kinase inhibitor (TKI) therapy in lung adenocarcinoma (LUAD). Here, we characterized the clinicopathologic features associated with EGFR mutations via peptide nucleic acid clamping-assisted fluorescence melting curve analysis (PANAMutyper) and evaluated the feasibility of targeted deep sequencing for detecting the mutations.
Methods:
We examined EGFR mutations in exons 18 through 21 for 2,088 LUADs from July 2017 to April 2020 using PANAMutyper. Of these, we performed targeted deep sequencing in 73 patients and evaluated EGFR-mutation status and TKI clinical response.
Results:
EGFR mutation was identified in 55.7% of LUADs by PANAMutyper, with mutation rates higher in females (69.3%) and never smokers (67.1%) and highest in the age range of 50 to 59 years (64.9%). For the 73 patients evaluated using both methods, next-generation sequencing (NGS) identified EGFR mutation–positive results in 14 of 61 patients (23.0%) who were EGFR-negative according to PANAMutyper testing. Of the 10 patients reportedly harboring a sensitizing mutation according to NGS, seven received TKI treatment, with all showing partial response or stable disease. In the 12 PANAMutyper-positive cases, NGS identified two additional mutations in exon 18, whereas a discordant negative result was observed in two cases.
Conclusions
Although PANAMutyper identified high frequencies of EGFR mutations, targeted deep sequencing revealed additional uncommon EGFR mutations. These findings suggested that appropriate use of NGS may benefit LUAD patients with otherwise negative screening test results.

Objectives:
This paper provides evidence for the improvement of the local and national longterm psychiatric emergency response system by analyzing emergency response cases for psychiatric crisis intervention conducted over three years at the Jeonbuk State Mental Health Welfare Center.
Methods:
From August 1, 2020, to December 31, 2023, 314 cases of emergency response for psychiatric crisis intervention were analyzed. The analysis included factors such as gender, age, marital status, location, classification of psychiatric crises, referral pathways, intervention response time, counseling history, location of intervention, types of mental health issues, types of suicidal issues, psychiatric treatment history, suicide plans and attempts, outcomes of major interventions, levels of depression, alcohol consumption, and suicidal behavior.
Results:
The emergency response for psychiatric crisis intervention had a higher proportion of suicide counseling compared to general mental health emergencies, and most cases were referred through administrative agencies such as the police and fire department. The majority of intervention targets were first-time counselees, classified as high-risk individuals because of depression, alcohol consumption, and suicidal behavior, and either discontinued or were maintaining medication treatment.
Conclusion
This study illustrated the major role of emergency response in psychiatric crisis intervention and the need for strengthening networks with police, fire departments, and relevant agencies, and improving the treatment of care staff and public awareness. In addition, this study provides evidence for predicting risk factors and offering preventive and preemptive measures.
