Background: Although many guidelines recommend performing lymph node dissection (LND) during surgery for intrahepatic cholangiocarcinoma (ICC), there is no evidence for patients with incidentally detected ICC who did not undergo LND. This study aimed to identify the role of LND in patients with incidental ICC.

Methods: The data from 284 patients who had undergone radical surgery for ICC from 2000 to 2020 were retrospectively reviewed. The enrolled patients were divided into 3 groups according to their T stage (T1 vs T2 vs T3 + 4). Moreover, the patients of each T group were divided into 3 groups according to their nodal status (N0 vs N1 vs Nx) and their survival outcomes were compared.

Results: Survival outcomes of Nx group were statistically similar to that of N0 group in T1 stage (Nx vs N0: disease-free survival [DFS] [months], 129.0 [75.6-182.4] vs 125.0 [65.7-184.3], P = .948; overall survival [OS] [months], 175.0 [153.9-196.1] vs 173.0 [109.0-237.0], P = .443). In contrast, survival outcomes of Nx group in the other T stage (T2 and T3 + 4) were poorer than that of N0 group and were better than that of N1 group. In addition, in the Nx subgroup analysis according to T stage, T1 group showed significantly better survival outcomes than the other groups (T1 vs T2 vs T3 + 4: DFS [months], 129.0 [75.9-182.1] vs 16.0 [9.8-22.2] vs 13.0 [0.3-25.7], P < .001; OS [months], 175.0 [153.9-196.1] vs 53.0 [30.8-75.2] vs 37.0 [17.6-56.4], P < .001).

Conclusion: Patients with ICC incidentally diagnosed as having T2 or above T stage may consider additional LND.

Introduction: Many patients acutely self-poisoned with organophosphorus insecticides have co-ingested ethanol. Currently, profenofos 50% emulsifiable concentrate (EC50) is commonly ingested for self-harm in Sri Lanka. Clinical experience suggests that ethanol co-ingestion makes management more difficult.

Impact of Frailty on Antihypertensive Treatment in Older Adults.

Hypertension

January 2025

The George Institute for Global Health, Faculty of Medicine, University of New South Wales, Newtown, Australia (L.C., S.Y., N.E., M.W., T.L., Y.G., C.S.A., K.H., X.C., R.P.).

Background: The association between systolic blood pressure and all-cause mortality differs between frail and nonfrail individuals, highlighting uncertainties about the effectiveness of antihypertensive treatments in frail populations.

Methods: Using data from the SHEP trial (Systolic Hypertension in the Elderly Program), a baseline frailty index (FI), including 55 variables, was constructed. Fine-Gray subdistribution hazard models and Cox proportional hazards regression models were used to explore the association between baseline FI and the risks of stroke, cardiovascular disease, and all-cause death, as well as to examine whether the impact of antihypertensive treatment on these outcomes was modified by baseline FI.

Enteropathogens are major contributors to mortality and morbidity, particularly in settings with limited access to water, sanitation, and hygiene infrastructure. To assess transmission pathways associated with enteropathogen infection, we measured household environmental conditions and assayed 22 enteropathogens using TaqMan Array Cards in stool samples from 276 six-month-old children living in communities along a rural-urban gradient in Northern Ecuador. We utilized multivariable models, risk factor importance, and distance-based statistical methods to test factors associated with infection.

Objective: Among the different subtypes of invasive lung adenocarcinoma, lepidic predominant adenocarcinoma (LPA) has been recognized as the lowest-risk subtype with good prognosis. The aim of this study is to provide insight into the heterogeneity within LPA tumors and to better understand the influence of other sub-histologies on survival outcome.

Methods: Overall, 75 consecutive patients with LPA in pathologic stage I (TNM 8th edition) who underwent resection between 2010 and 2022 were included into this retrospective, single center analysis.

Objective: To develop a Metabolic Derangement Score (MDS) based on parameters available after initial testing and assess the score's ability to predict survival after out-of hospital cardiac arrest (OHCA) and the likely usefulness of extracorporeal life support (ECLS).

Methods: A total of 5100 cases in the Korean Cardiac Arrest Research Consortium registry were included. Patients' mean age was 67 years, and 69% were men.
