Background/Aims: Cardiovascular disease is the leading cause of death worldwide. This study aimed to investigate the recent nationwide trends in major dietary risk factors for dyslipidemia and atherosclerosis. Methods: We estimated age-standardized mean intakes of fresh fruits, fresh vegetables, whole grains, dietary fiber, and sugar-sweetened beverages (SSBs); and mean percentage of energy intake from protein, total fat, saturated fat, and polyunsaturated fat using nationally representative samples from the Korean National Health Examination and Nutrition Survey 2013–2022. To assess overall diet quality, we calculated mean Korean Healthy Eating Index (KHEI) (range 0–100, higher scores indicating greater diet quality). Results: In 2013–2022, there were overall decreasing trends in age-standardized mean KHEI score and intakes of fresh fruits and vegetables, whole grains, and dietary fiber; and overall increasing trends in mean intakes of SSBs, protein, and dietary fat among both male and female. The KHEI score increased in older adults aged ≥ 60 years, whereas it decreased among younger adults. Throughout the study period, younger adults tended to have lower intakes of fresh fruits, fresh vegetables, and whole grains; higher intakes of SSBs, protein, and dietary fat; and lower KHEI score. The mean KHEI score was lower in male (vs. female) and lower (vs. higher) income groups. Conclusions Our data suggest that, from 2013 to 2022, there was a trend toward an unhealthy diet in Korean adults. Our findings also suggest dietary inequalities among age, sex, and income groups, suggesting the need for more intense interventions targeting the vulnerable populations.

Objective:To explore the characteristics of SMN1 gene variants and carry out functional verification for two children with Spinal muscular atrophy (SMA). Methods:Two male children with complicated SMA diagnosed at the Children′s Hospital Affiliated to Capital Institute of Pediatrics respectively in July 2021 and April 2022 due to delayed or retrograde motor development were selected as the study subjects. Clinical data of the children were collected. Primary culture of skin fibroblasts was carried out, and peripheral blood samples were collected from both children and their parents. Multiplex ligation-dependent probe amplification, combined long-range PCR and nested PCR, and Sanger sequencing were carried out to detect the copy number and variants of the SMN1 gene. Absolute quantitative real-time PCR, Western blotting and immunofluorescence were used to determine the transcriptional level of the SMN gene, expression of the SMN protein, and the number of functional SMN protein complexes (gems body), respectively. This study was approved by Medical Ethics Committee of the Children′s Hospital Affiliated to Capital Institute of Pediatrics (Ethics No. SHERLLM2021009). Results:Child 1, a 1-year-old boy, was clinically diagnosed with type 1 SMA. Child 2, a 2-and-a-half-year-old boy, was clinically diagnosed with type 3 SMA. Both children were found to harbor a paternally derived SMN1 deletion and a maternally derived SMN1 gene variant, namely c. 824G>T (p.Gly275Val) and c. 884A>T (p.*295Leu). Compared with the normal controls and carriers, the levels of full-length SMN1 transcripts in their peripheral blood and skin fibroblast cell lines were significantly decreased ( P<0.05), and the levels of SMN protein normalized to that of β-actin, and the numbers of gems bodies in the primary fibroblast cells were also significantly lower ( P<0.05). Based on the guidelines from the American College of Medical Genetics and Genomics, both variants were classified as likely pathogenic (PS3+ PM3+ PM5+ PP3; PS3+ PM3+ PM4+ PP3). Following the diagnosis, both children had received nusinersen treatment. Although their motor function was improved, child 1 still died at the age of 2 due to severe pulmonary infection. The walking ability of child 2 was significantly improved, and his prognosis appeared to be good. Conclusion:Two cases of clinically complicated SMA have been confirmed by genetic testing and experimental studies, which has provided a reference for their accurate treatment.

Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis is known to have various clinical symptoms, but usually shows acute behavioral changes, memory deficit, speech problems and dysregulation of autonomic nervous system. Recently, it has been found that NMDA receptors perform important roles not only in central nervous system but also in peripheral organs, like control the cardiac rhythm by located in the myocardium and cardiac conduction system. The authors would like to report a case of bradycardia accompanied by anti-NMDA receptor encephalitis.

Herpes simplex encephalitis is known to cause intracranial hypertension and cerebral edema. When cerebral edema occurs, venous sinuses are compressed, resulting in congestion and thrombosis. An arteriovenous fistula may form as a result, particularly in conjunction with superior sagittal sinus thrombosis. In this report, the authors describe a patient with protein S and C deficiency who developed venous sinus thrombosis and dural arteriovenous fistula after experiencing herpes simplex encephalitis.

Objective:To explore the distribution of the copy number of survival motor neuron gene 2 ( SMN2) and the transcript level of the full-length SMN2 ( fl-SMN2) transcript level in patients with type 1-3 spinal muscular atrophy (SMA), and to evaluate their influences on disease severity, progression, and prognosis. Methods:It was a retrospective study involving 78 therapy-naive SMA patients with SMN1 gene homozygous deletion who were diagnosed and treated in the Capital Institute of Pediatrics from January 2019 to December 2021.Cross-sectional clinical data, including age at onset, motor milestones, and complications were recorded.They were followed up for monitoring motor function degeneration and survival.The copy number of SMN2 and the transcript level of fl-SMN2 were detected.Differences between groups were compared by the Student′s t-test or One- Way ANOVA or Chi- square test.Kaplan-Meier analysis was used for survival analysis, and Kendall′ s tau- c was performed to assess the correlation of these two biomarkers with SMA phenotypes, age at onset, motor milestones, and survival. Results:Of the 78 SMA patients, there were 17 cases (21.8%) of type 1, 34 cases(43.6%) of type 2, and 27 cases(34.6%) of type 3.Seven cases(41.2%) type 1 SMA patients died, with a median survival time of 11 months, and no deaths were observed in type 2 and type 3 SMA patients.There was a significant difference in the median age at onset among SMA patients with 2, 3, and 4 copies of SMN2 (1.8, 12.0, and 24.0 months, respectively; F=4.943, P=0.01). The mean transcript level of fl-SMN2 in type 1, 2 and 3 SMA patients were 196.25±68.79, 331.21±108.79 and 455.69±122.27, respectively ( F=37.154, P<0.001). The survival rate of SMA with 2 SMN2 copies at 1, 2, and 5 years were 50.5%, 0, and 0, respectively, and their median survival age was 7 months.The survival rate of SMA with 3 and 4 SMN2 copies at 5 years were 97.4% and 100.0%, respectively.Moreover, a negative correlation was observed between the transcript level of fl-SMN2 and phenotype severity ( Kendall′ s tau- c=-0.444, P<0.001), and the transcript level of fl-SMN2 of the survival group was much higher than that of the death group (342.93±125.74 vs.212.14±92.31). More copies of SMN2 and higher transcript level of fl- SMN2 indicated more motor function acquisitions (head control, sitting and walking) ( P<0.001). In addition, there was a significant difference in the transcription level of fl-SMN2 between the undegenerated group and the degenerated group in sitting and standing ( F=5.432, P=0.023 and F=4.315, P=0.047, respectively). Conclusions:Both the copy number of SMN2 and the transcript level of fl-SMN2 are correlated with SMA severity, survival, and motor milestones, serving as valuable biomarkers for evaluating phenotypic severity of SMA.The transcript level of fl-SMN2 s may play an important role in the degeneration of sitting and standing.

Objectives: . A crooked nose is frequently caused by nasal bony vault deviation, and proper management of the bony vault is an integral part of rhinoplasty. Conventional osteotomy to correct a deviated nose favors simultaneous medial and lateral osteotomies, which allows the free independent movement of each nasal bone. However, patient satisfaction with deviated nose surgery is sometimes low. In the present study, we introduce a one-unit osteotomy procedure that combines bilateral and root osteotomies with unilateral triangular bony wedge resection to allow symmetry of both nasal bones. Methods: . Twenty consecutive patients who presented with bony vault deviation and underwent one-unit osteotomy were enrolled in this retrospective single-center study. The Nasal Obstruction Symptom Evaluation (NOSE) questionnaire was used to evaluate each patient’s functional outcome. The angle of bony vault deviation before and after one-unit osteotomy was measured using a protractor and compared with the results of 14 patients who had undergone conventional osteotomy. The improvement in dorsal deviation was evaluated using facial photography preoperatively and 3 months postoperatively. Results: . NOSE values improved from 8.4±6.4 to 4.1±4.2 (P =0.021). The angle of bony vault deviation improved from 6.9°±2.2° to 2.1°±1.2° (P <0.001) in one-unit osteotomy and from 7.3°±4.0° to 2.7°±1.2° (P =0.001) in conventional osteotomy. The preoperative deviation angle improved by 70.3% in one-unit osteotomy compared with 56.6% in conventional osteotomy, which was a significant difference (P =0.033). The mean grade of the postoperative esthetic outcomes for the remaining deviation was 1.6±0.5, which was similar to that in the conventional osteotomy group. Conclusion . One-unit osteotomy is a relatively simple procedure that balances the width of both lateral walls by removing excessive bony fragments from the wider bony wall and providing better structural integrity. This technique improves functional outcomes and has equivalent esthetic results to those of the traditional procedure.
