This study aims to develop a standardized informed consent system for whole-genome sequencing (WGS)-based newborn screening (NBS) in Korea through a policy design approach grounded in the domestic legal and policy context. We conducted an integrated literature review of international norms, domestic legal frameworks, guidelines, and major overseas WGS-based NBS programs using a common analytical framework. To develop a consent model feasible in the Korean context, we also analyzed stakeholder evidence from parent interviews and a clinician survey focused on consentrelated issues. The findings indicate that the current Korean legal and institutional framework does not adequately address long-term storage, reanalysis, recontact, and the transfer of decision-making authority as the child matures. Based on these findings, we propose a Korean informed consent model consisting of a staged consent pathway spanning antenatal, postnatal, and adulthood-related decision points; tiered consent options for the return of results; and safeguards against disadvantage or discrimination related to participation, non-participation, or withdrawal. The study further suggests that implementation will require broader legal and procedural clarification across the relevant regulatory framework, along with the continued development of education and counseling strategies.

Informed consent for whole-genome sequencing (WGS)-based newborn screening presents distinctive ethical and legal challenges, particularly in balancing parental consent given on behalf of the child with the progressive realization of children’s rights. This study examines the issues discussed in the literature and proposes consent frameworks that are responsive to evolving clinical and societal contexts. A systematic literature review was conducted in accordance with PRISMA 2020 guidelines, analyzing 19 empirical, normative, and legal studies. The synthesis identified persistent tensions between safeguarding parental autonomy and ensuring the child’s future selfdetermination, alongside challenges in determining the scope, timing, and format of genomic information disclosure. International models increasingly adopt dynamic consent processes, such as staged consent or re-consent upon reaching legal capacity. These approaches illustrate the feasibility of aligning clinical utility, public health objectives, and rights-based ethics within largescale genomic programs. Based on its findings, this study recommends the implementation of staged consent mechanisms, transparent disclosure protocols, and procedural safeguards tailored to domestic legal and political frameworks. Such evolving consent practices are expected to support the development of ethically robust and socially sustainable governance for WGS-based newborn screening.

Purpose:
This study aimed to evaluate the effect of prophylactic abdominal drainage (AD) in laparoscopic hemicolectomy, focusing on assessing postoperative pain outcomes.
Methods:
Patients were categorized into two groups: those with and without AD (AD group vs.no-AD group). A numerical rating scale (NRS) was used to assess postoperative pain on each postoperative day (POD). Further, the inverse probability of treatment weighting (IPTW) method was used to reduce intergroup bias.
Results:
In total, 204 patients who underwent laparoscopic hemicolectomies by a single surgeon between June 2013 and September 2022 at a single institution were retrospectively reviewed. After adjusting for IPTW, NRS scores on POD 2 were significantly lower in the no-AD group (3.2 ± 0.8 vs. 3.4 ± 0.8, p = 0.043). Further examination of postoperative outcomes showed no statistically significant differences in complications between the AD (17.3%) and no-AD (12.4%) groups (p = 0.170). The postoperative length of hospital stay was 7.3 ± 2.8 days in the AD group and 6.9 ± 3.0 days in the no-AD group, with no significant difference (p = 0.298). Time to first flatus was 3.0 ± 0.9 days in the AD group and 2.7 ± 0.9 days in the no-AD group, with no significant difference (p = 0.078). Regarding readmission within 1 month, there were four cases each in the AD (2.3%) and no-AD (1.7%) groups, with no significant difference (p = 0.733).
Conclusion
Laparoscopic hemicolectomy without AD resulted in no significant differences in postoperative clinical outcomes, except for postoperative pain. This finding suggests that prophylactic AD may exacerbate postoperative pain.

Background:
The symptoms of adrenal insufficiency (AI) overlap with the common effects of advanced cancer and chemotherapy. Considering that AI may negatively affect the overall prognosis of cancer patients if not diagnosed in a timely manner, we analyzed the incidence, risk factors, and predictive methods of AI in cancer patients.
Methods:
We retrospectively analyzed the medical records of 184 adult patients with malignancy who underwent a rapid adrenocorticotrophic hormone stimulation test in the medical hospitalist units of a tertiary hospital. Their baseline characteristics and clinical features were evaluated, and the risk factors for AI were identified using logistic regression analysis.
Results:
Of the study patients, 65 (35%) were diagnosed with AI, in whom general weakness (63%) was the most common symptom. Multivariate logistic regression showed that eosinophilia (adjusted odds ratio [aOR], 4.28; 95% confidence interval [CI], 1.10–16.63; P = 0.036), history of steroid use (aOR, 2.37; 95% CI, 1.10–5.15; P = 0.028), and history of megestrol acetate use (aOR, 2.71; 95% CI, 1.38–5.33; P = 0.004) were associated with AI. Baseline cortisol levels of 6.2 μg/dL and 12.85 μg/dL showed a specificity of 95.0% and 95.4% for AI diagnosis, respectively.
Conclusion
AI was found in about one-third of patients with cancer who showed general symptoms that may be easily masked by cancer or chemotherapy, suggesting that clinical suspicion of AI is important while treating cancer patients. History of corticosteroids or megestrol acetate were risk factors for AI and eosinophilia was a pre-test predictor of AI.Baseline cortisol level appears to be a useful adjunct marker for AI.

BACKGROUND: Various regimens have been studied in extension of a preexisting labor epidural for emergency cesarean section. Lumbar epidural analgesia for delivery is safe and efficient. We compared retrospectively 0.5% ropivacaine with fentanyl and 0.75% ropivacaine in extension of a preexisting labor epidural for emergency cesarean section. METHODS: We investigated medical records of 61 parturients in extension of a preexisting labor epidural for emergency cesarean section. There were two regimens which was 0.5% ropivacaine with fentanyl (group 1) and 0.75% ropivacaine (group 2). We recorded demographic data, local anesthetic dose, surgical readiness time, maximum level of sensory block, surgery time, intravenous supplementation, number of hypotension and total dose of ephedrine between two groups. RESULTS: There were no differences between the study groups in demographic data, surgical readiness time, maximum sensory block level, intravenous supplementation, incidence of hypotension and total dose of ephedrine. Local anesthetic volume was larger in group 1 than group 2, but local anesthetic doses were lower in group 1 than group 2. CONCLUSIONS: 0.5% Ropivacaine with fentanyl regimen is as fast and efficacious as 0.75% ropivacaine in extension of a preexisting labor epidural for cesarean section and reduces the requiring total local anesthetic dose.

Terminal cancer pain is always a challenge to pain doctors.If the focus of the cancer pain is located in the restricted area, it is easy to control the pain. However, if the focus of cancer pain is widespread, it is very difficult to control the pain and it makes pain doctors embarrassed.Nowadays, the ultrasound-guided nerve block become a popular method. It is easy to find the nerve and helps to insert the catheter around the nerve for the continuous nerve block. We encountered a patient who was 59 years old with a stomach cancer and vertebral metastasis. He complained about the pain in his abdomen, back and left thigh. His abdominal and back pain vanished with the use of continuous lumbar epidural injection. However, the patient still complained about the pain and numbness on the left thigh, because of this, he couldn't get any sleep.We tried a continuous femoral nerve block under the ultrasound guidance, after that his pain was gone.The ultrasound-guided nerve block will be very helpful to control the pain.
