Heart failure (HF) is a major cause of mortality and morbidity in South Korea, imposing substantial physical, emotional, and financial burdens on patients and society. Despite the high burden of symptom and complex care needs of HF patients, palliative care and hospice services remain underutilized in South Korea due to cultural, institutional, and knowledge-related barriers. This position statement from the Korean Society of Heart Failure emphasizes the need for integrating palliative and hospice care into HF management to improve quality of life and support holistic care for patients and their families. By clarifying the role of palliative care in HF and proposing practical referral criteria, this position statement aims to bridge the gap between HF and palliative care services in South Korea, ultimately improving patient-centered outcomes and aligning treatment with the goals and values of HF patients.

Purpose: There are many studies regarding the increased relationship between pregnancy outcomes of singleton with endometriosis. However, there was limited evidence of twin pregnancies with endometriosis. This study aimed to compare the pregnancy outcomes and complications in twin pregnancies with or without endometriosis in a single institution. Materials and Methods: From January 2011 to July 2022, a retrospective analysis of twin pregnancies was conducted. The endometriosis group included patient with histological or visual confirmation before pregnancy or during cesarean section. Pregnancy outcomes and complications were compared between the two groups. Results: Out of 1714 patients examined, 127 (7.4%) were included in the endometriosis group. Maternal body mass index (BMI) was lower in the endometriosis group (p<0.001). There were no significant differences in maternal age, mode of conception, chorionicity, and pregnancy outcomes, such as gestational age at delivery (p=0.835) and the preterm birth rate (p=0.579). The endometriosis group had a significantly higher rate of obstetrical complication: small for gestational age (SGA) <10% (p=0.029). However, after adjustment for BMI, the endometriosis group showed no statistical significance in obstetrical complications, including SGA (adjusted odds ratio, 1.568; 95% confidence interval, 0.984–2.499; p=0.059). Conclusion Twin pregnancies with endometriosis were not related to adverse effects on pregnancy outcomes and obstetrical complications. To confirm these outcomes, further large prospective studies are required.

Background: Various treatments exist for addressing volume loss in atrophic scars. Although laser therapy has gained traction in treating atrophic scars, it is associated with side effects, such as post-inflammatory hyperpigmentation or erythema. Additionally, not all types of atrophic scars respond optimally to laser therapy, even after multiple sessions. Objective: This study aimed to evaluate the efficacy and safety of punch elevation for atrophic scars that yielded unsatisfactory outcomes after repeated laser treatment sessions. Methods: Seven patients with atrophic scars on their facial area underwent punch elevation, concurrently supplemented by fractional CO2 laser application to the scar margins. Improvement in volume restoration of atrophic scars was assessed via investigator evaluation and 3-dimensional (3D) image analysis. Results: After 1 month, median volume (interquartile range) of depression improved from 4.39 mm3 (2.23∼9.90 mm3 ) to 1.97 mm3 (1.46∼7.50 mm3 ), indicating a statistically significant difference post-punch elevation (p=0.018). No serious adverse events were reported during follow-up. Conclusion The efficacy of the punch elevation was objectively evaluated. Punch elevation is a safe and effective therapeutic avenue for atrophic scars that exhibit resistance to laser or alternative interventions.

Aggressive digital papillary adenoma (ADPA) is a rare tumor of the sweat glands. They usually present as solitary masses, with or without pain, and are most commonly observed in the fingers. A 19-year-old man presented with a solitary, protruding lesion on the right big toe that had enlarged 6 months previously. The biopsy specimen revealed a well-marginated mass with papillary projections and tubular structures. On foot magnetic resonance imaging, there was no invasion, and chest radiography showed no metastasis. Based on these findings, the tumor was diagnosed as ADPA, and wide excision was performed. Herein, we report a rare sweat gland tumor on the toe that was diagnosed as an ADPA.

Background: Although patients with psoriasis have an increased risk of cancers, little is known about the risk of psoriasis in cancer patients. Objective: We aimed to comparatively analyze the incidence and risk factors of psoriasis in gastric cancer patients who underwent gastrectomy and in the general population. Methods: A nationwide retrospective cohort of 52,608 gastric cancer survivors (2007~2015) was compared to 123,438 matched controls from the general population to estimate the incidence and hazard ratio (HR) of new-onset psoriasis. We also calculated the HRs for psoriasis according to adjuvant cancer treatment, obesity, and vitamin B12 supplementation in gastric cancer survivors. Results: During a mean follow-up of 6.85 years, 645 of the 52,608 gastric cancer patients developed psoriasis, while 1,806 in the 123,438 matched control group developed psoriasis. Gastric cancer patients had a decreased risk of psoriasis (HR, 0.86; 95% confidence interval, 0.79~0.94), especially those who underwent subtotal gastrectomy. We found that vitamin B12 supplementation for more than 3 years had an additive effect on decreasing the risk of psoriasis in gastric cancer patients who underwent subtotal gastrectomy. Total gastrectomy, radio/chemotherapy, and obesity did not affect the risk of psoriasis in gastric cancer survivors. Conclusion The incidence of psoriasis is slightly lower in gastric cancer survivors than in the general population. Our results suggest that the development of psoriasis may be reduced by removing the source of systemic inflammation caused by Helicobacter pylori infection through subtotal gastrectomy in gastric cancer survivors.

Background/Aims: Adjuvant chemotherapy is the standard of care for resected stage II-IIIA non-small cell lung cancer (NCSLC). The efficacy of adjuvant chemotherapy in stage IB (< 4 cm) NSCLC with high-risk factors is controversial. Methods: This retrospective multicenter study included 285 stage IB NSCLC patients with high-risk factors according to the 8th edition tumor, node, metastasis (TNM) classification from four academic hospitals. High-risk factors included visceral pleural invasion, vascular invasion, lymphatic invasion, lung neuroendocrine tumors, and micropapillary histology patterns. Results: Of the 285 patients, 127 (44.6%) were included in the adjuvant chemotherapy group and 158 (55.4%) were included in the non-adjuvant chemotherapy group. The median follow-up was 41.5 months. Patients in the adjuvant chemotherapy group had a significantly reduced recurrence rate and risk of mortality than those in the non-adjuvant chemotherapy group (hazards ratio, 0.408; 95% confidence interval, 0.221 to 0.754; p = 0.004 and hazards ratio, 0.176; 95% confidence interval, 0.057 to 0.546; p = 0.003, respectively). Adjuvant chemotherapy should be particularly considered for the high-risk factors such as visceral pleural involvement or vascular invasion. Based on the subgroup analysis, adjuvant chemotherapy should be considered when visceral pleural involvement is present, even if the tumor size is < 3 cm. Conclusions Adjuvant chemotherapy may be useful for patients with stage IB NSCLC with high-risk factors and is more relevant for patients with visceral pleural involvement or vascular invasion.

A clinical practice guideline for patients in the dying process in general wards and their families, developed through an evidence-based process, is presented herein. The purpose of this guideline is to enable a peaceful death based on an understanding of suitable management of patients’ physical and mental symptoms, psychological support, appropriate deci-sion-making, family care, and clearly-defined team roles. Although there are limits to the available evidence regarding medical issues in patients facing death, the final recommendations were determined from expert advice and feedback, considering values and preferences related to medical treatment, benefits and harms, and applicability in the real world. This guideline should be applied in a way that takes into account specific health care environments, including the resources of medical staff and differences in the available resources of each institution. This guideline can be used by all medical institutions in South Korea.

Purpose: The objective of this study was to analyze the results of several noninvasive prenatal tests (NIPTs) from a single center and confirm their efficacy and reliability. In addition, we aimed to confirm the changes in the number of invasive tests performed after introducing NIPT. Materials and Methods: NIPT data from a large single center from March 2014 to November 2018 were analyzed. Karyotyping was confirmed based on chorionic villus sampling, amniocentesis, or postnatal cord/peripheral blood sampling. Data on maternal age, gestational age, fetal fraction, and ultrasonographic results were analyzed. As the secondary outcome, the number of amniocentesis cases before and after the introduction of NIPT was compared. Results: Overall, 1,591 single pregnancy cases that underwent NIPT were enrolled. The mean maternal age was 36.05 (22-45) years. The average gestational age and fetal fraction were 12+1 (9+3 to 27+1) weeks and 10.95% (3.6% to 31.3%), respectively. A total of 1,544 cases (97.0%) were reported to have negative NIPT results and 40 (2.5%) had positive NIPT results. The sensitivity and specificity of the overall abnormalities in NIPT were 96.29% and 99.36%, respectively. The positive predictive value (PPV) and negative predictive value were 72.22% and 99.93% respectively. The mean number of amniocentesis cases were 21.7 per month (21.7±3.9), which significantly decreased from 31.5 per month (31.5±4.8) before conducting NIPT as a screening test. Conclusion NIPT is currently a useful, powerful, and safe screening test. In particular, trisomy 21 is highly specific due to its high PPV. NIPT can reduce the potential risks of procedure-related miscarriages during invasive testing.

Background: Estrogen controls the pubertal growth spurt, growth plate closure, and accretion of bone mineral density (BMD) of long bones after biding estrogen receptor (ER).There are two subtypes of ER, ERα and ERβ. If each ER subtype has different effects, we may control those actions by manipulating the estrogen binding intensity to each ER subtype and increase the final adult height without markedly reducing BMD or impairing reproductive functions. The purpose of our study was to compare these effects of ERα and ERβ on long bones in ovariectomized rats. Methods: Thirty female rats were ovariectomized and randomly divided into 3 groups. The control, propylpyrazole triol (PPT), and 2,3-bis (4-hydroxyphenyl) propionitrile (DPN) groups were subcutaneously injected for 5 weeks with sesame oil, PPT as an ERα agonist, and DPN as an ERβ agonist, respectively. The crown-lump length and body weight were measured weekly.BMD, serum levels of growth hormone (GH) and estradiol were checked before and after 5 weeks of injections. Pituitary GH1 expression levels were determined with quantitative realtime polymerase chain reaction, the proximal tibias were dissected, decalcified and stained with hematoxylin-eosin, and the thicknesses of epiphyseal plates including proliferative and hypertrophic zones were measured in 20-evenly divided sites after 5 weeks of injections. Comparisons for auxological data, serum hormone and pituitary GH1 expression levels, BMD, and epiphyseal plate thicknesses among 3 groups before and after injections were conducted. Results: There was no significant difference in body lengths among 3 groups. The body weights were significantly lower, but, serum GH, pituitary GH1 expression levels, and BMDs were higher in PPT group than the other 2 groups after 5 weeks of injections. There was no significant difference in the thicknesses of the total epiphyseal plate, proliferative, and hypertrophic zone among 3 groups. Conclusion ERα is more involved in pituitary GH secretion and bone mineral deposition than ERβ. Weight gain might be prevented with the ERα agonist.

Hypereosinophilia, defined as an absolute eosinophil count of >1,500/μL, can be caused by a number of allergic, infectious, paraneoplastic and neoplastic disorders. In cases of hypereosinophilia with lymphoid proliferation, pathological confirmation is essential to exclude either myeloid or lymphoid malignancy. A 38-year-old woman with both cervical lymphadenopathies and peripheral blood eosinophilia visited our clinic. She had already performed core biopsy of lymph nodes and diagnosed as Kimura disease at a regional hospital. At the time of our clinic visit, there were no palpable cervical lymph nodes. The blood test showed hypereosinophilia with a high total IgE level. There was no evidence of tissue infiltration of eosinophils except for duodenitis with eosinophilic infiltration. Based on these findings, she was diagnosed as Kimura disease. She treated with high-dose systemic corticosteroid (1 mg/kg) and additional immunosuppressants sequentially used cyclophosphamide and cyclosporine. However, her eosinophilia waxed and waned, and a left inguinal mass was newly found. Excisional biopsy findings showed large atypical lymphoid cells with numerous eosinophilis, and immunohistochemistry showed CD3+, CD20−, CD30+ and anaplastic lymphoma kinase (ALK). The final diagnosis was ALK-negative anaplastic large cell lymphoma. We report a case of anaplastic large cell lymphoma with marked peripheral eosinophilia misdiagnosed as Kimura disease. In the case of hypereosinophilia with lymphadenopathy, it is necessary to differentiate hematologic diseases through immunochemical staining.
