Purpose: Nutritional markers, such as total protein, albumin, and vitamin D have been reportedly associated with neonatal outcomes. This study aimed to assess the correlation between nutritional markers at birth and the need for respiratory support on the first day of life. Methods: This retrospective study included 94 newborns admitted to the neonatal intensive care unit of Kyungpook National University Children's Hospital between March and December 2017. We measured levels of nutritional markers, including serum total protein, albumin, ferritin, 25-hydroxyvitamin D (25-OHD), and prealbumin, from cord blood or blood sample within 24 hours after birth. Respiratory support was defined as the use of nasal continuous positive airway pressure, humidified high-flow nasal cannula, or mechanical ventilation on the first day of life. Results: The mean gestational age and birth weight were 36.6±2.3 weeks and 2,714± 575 g, respectively. Serum total protein, albumin, prealbumin, and ferritin levels at birth were significantly correlated with gestational age and birth weight. Total protein, albumin, ferritin, and 25-OHD levels were not correlated with the time to recover birth weight after adjusting for gestational age. Moreover, prealbumin levels at birth were significantly lower in small-for-gestational-age infants than in appropriate-forgestational-age infants. The need for respiratory support on the first day of life decreased 0.058- and 0.001-fold for every 1 g/dL increase in serum total protein (95% confidence interval [CI], 0.004 to 0.833; P=0.036) and albumin (95% CI, 0.000 to 0.136; P=0.009) levels, respectively. Conclusion: Nutritional status at birth could be associated with the need for respiratory support on the first day of life, regardless of the Apgar score.

68Ga-PSMA-11 합성 시간 단축을 위한 자동합성장치의 최적화 및 안정성 연구

Ji Hoon Kang,Sang Min SHIN,Young Si PARK,Hea Ji KIM,Hwa Youn JANG 대한임상검사과학회 2024 대한임상검사과학회지(KJCLS) Vol.56 No.2

68Ga-PSMA-11은 전립선특이막항원(PSMA)에 결합하는 Glu-urea-Lys 기반 리간드에 68Ga 방사성동위원소를 표지한 PET 제제로, 재발성 전립선암 및 전이의 진단과 치료를 위한 영상화에 널리 사용한다. 그러나 의료기관에서 68Ga-PSMA-11을 제조하고 품질검사 시험 결과가 나올 때까지의 시간은 평균 60 분 이상 소요되어, 하루에 사용할 수 있는 68Ge/68Ga 제너레이터 용량이 제한된다. 또한 제너레이터의 1,110 MBq (30 mCi) 의 명목상 활성을 제공하지만 시간이 지남에 따라 감소하고, 표지 수율이 불규칙적으로 저하된다. 이로 인해 의료기관에서는 추가 조제를 통해 동일한 용출을 유지해야 하며, 이 과정에서 작업자의 피폭 위험이 증가하고, 환자의 대기 시간이 길어지며, 제조 스케줄 조정이 불가피한 임상적 문제가 발생한다. 본 연구는 이러한 문제를 해결하기 위해 68Ga-PSMA-11의 조제 시간을 단축하고 자동합성장치를 최적화하는 것을 목표로 하였다. 자동합성장치를 이용한 합성 절차에서 68Ga과 PSMA-11 전구체의 반응 시간을 단축하고 불순물 제거 세척 단계의 횟수를 조절하여 동일한 품질을 유지하면서도 더 신속하고 경제적인 방법을 시험했다. 그 결과, 최종 합성 시간을 30분에서 20분으로 단축하였고, HEPES 함량, 잔류용매 EtOH 함량, 방사화학적 순도 등의 품질 기준을 만족시켰다. 이는 추가 조제로 인한 작업자의 피폭문제와 환자의 대기 시간을 줄이고, 제조 스케줄 조정에도 문제가 없는 최적의 절차로 임상에서 적용할 수 있음을 시사한다. Gallium-68-prostate-specific membrane antigen-11 (68Ga-PSMA-11) is a positron emission tomography radiopharmaceutical that labels a Glu-urea-Lys-based ligand with 68Ga, binding specifically to the PSMA. It is used widely for imaging recurrent prostate cancer and metastases. On the other hand, the preparation and quality control testing of 68Ga-PSMA-11 in medical institutions takes over 60 minutes, limiting the daily capacity of 68Ge/68Ga generators. While the generator provides 1,110 MBq (30 mCi) nominally, its activity decreases over time, and the labeling yield declines irregularly. Consequently, additional preparations are needed, increasing radiation exposure for medical technicians, prolonging patient wait times, and necessitating production schedule adjustments. This study aimed to reduce the 68Ga-PSMA-11 preparation time and optimize the automated synthesis system. By shortening the reaction time between 68Ga and the PSMA-11 precursor and adjusting the number of purification steps, a faster and more cost-effective method was tested while maintaining quality. The final synthesis time was reduced from 30 to 20 minutes, meeting the standards for the HEPES content, residual solvent EtOH content, and radiochemical purity. This optimized procedure minimizes radiation exposure for medical technicians, reduces patient wait times, and maintains consistent production schedules, making it suitable for clinical application.

Background: The effect of BCAA administration on prolonged weightless muscle atrophy during growth phases is not well documented. The purpose of the present study was to examine the effect of BCAA administration on preventing the muscle atrophy induced by a hindlimb suspension in growing male rats. Methods: Male Wistar rats were assigned to 1 of 2 groups (n = 7/group): hindlimb suspension and hindlimb suspension with oral BCAA administration (600 mg·kg-1·day-1, valine 1: leucine 2: isoleucine 1). After 14 days of hindlimb suspension, weight and mRNA level of the soleus muscle were measured. Results: BCAA administration prevented the decrease in soleus muscle weight. BCAA administration attenuated atrogin-1 and MuRF1 mRNA expression which has been reported to play a pivotal role in muscle atrophy. Conclusion: BCAA could serve as an effective supplement for the prevention or treatment of preventing muscle atrophy, especially that caused by weightlessness.

Jang, Kyung-Sool,Park, Hea-Kwan,Joo, Won-Il,Ji, Chul,Lee, Kyung-Jin,Choi, Chang-Rak The Korean Neurosurgical Society 2005 Journal of Korean neurosurgical society Vol.37 No.5

Objective: Various methods of treatment for idiopathic cervical dystonia have been tried in the past with unsatisfactory results. The authors report cases of five patients who underwent selective peripheral denervation for spasmodic torticollis. Methods: Between July 2002 and December 2003, 5 patients underwent surgery at St. Mary's Hospital for spasmodic torticollis. Age of the patient at the onset of symptoms ranged from 29 to 56years (mean 43.75years). Selective peripheral denervation(SPD) was performed at 7 to 11 months after the onset of symptoms (mean 8.75 months). A patient was considered to be the candidate for surgery if conservative methods were unsuccessful and symptoms persisted for longer than 7months. In addition, 2patients who refused treatment with botulinum toxin were also enrolled in this study. Results: Although one patient underwent reoperation, all of the five patients' symptoms were improved after the operation. Clinically, patients with retrocollis showed better improvement than laterocollis patients. Conclusion: Although injection of botulinum toxin is the first-choice in treatment modality, when surgery is required, selective peripheral denervation provides good results with minimum side effects.

정승현,Ji‑Hun Jang,Hea‑Young Cho,오인준,이용복 한국약제학회 2020 Journal of Pharmaceutical Investigation Vol.50 No.2

Purpose The purpose of this study was to develop a sensitive method for quantifying cinnamic acid in human plasma using UPLC–ESI–MS/MS. Methods Cinnamic acid was separated using water containing 0.005% (v/v) formic acid and acetonitrile as a mobile phase by gradient elution at a flow rate 0.2 mL/min, equipped with a HALO-C18 column (2.1 × 100 mm, 2.7 μm). Quantitation of this analysis was performed on a triple quadrupole mass spectrometer employing electrospray ionization technique, operating in multiple reaction monitoring negative ion mode. The mass transitions were m/z 146.8 → 103.0 for cinnamic acid, and 432.9 → 225.0 for geniposide as internal standard. Liquid–liquid extraction and protein precipitation with ethyl acetate–methanol-1.2% acetic acid (4/16/1, v/v/v) were used in the sample extraction. Results The chromatograms showed high resolution, sensitivity, and selectivity with no interference with plasma constituents. The calibration curves for cinnamic acid in human plasma were 0.1–500 ng/mL and displayed excellent linearity with correlation coefficients (r) greater than 0.99. Both the intra- and inter-day precisions (CV%) were within 3.88% for human plasma. The accuracy was 99.34–106.69% for human plasma. In vitro plasma protein binding of cinnamic acid was 64.26 ± 1.89 and 65.50 ± 1.78% for the spiked human plasma concentrations of 100 and 1000 ng/mL, respectively. Conclusion The developed analytical method satisfied the criteria of international guidance and could be successfully applied to the pharmacokinetic study of cinnamic acid after oral administration of Socheongryong-tang tablets to humans.

Acardiac twin is a rare anomaly that occurs 1% in monochorionic twins and 1 in 35,000 pregnancies overall. Acardiac twin, also known as twin-reversed arterial perfusion (TRAP) sequence, involves a “pump” or donor twin perfusing a recipient or “acardiac” twin through vascular (usually arterial-arterial and venous-venous) anastomoses. Perinatal mortality rate for the pump twin has been reported to be 50~75%, mainly as a result of polyhydramnios, preterm labor, and congestive heart failure. Therefore, occlusion of the circulation to the acardiac twin has been recommended to improve perinatal outcome of the pump twin. Radiofrequency ablation of the acardiac twin effectively protects the pump twin from high-output cardiac failure and death. We report our experience in the treatment of patients with TRAP sequence using radio frequency ablation to stop perfusion to the acardiac twin.
