Background: Pregnancy in teenagers and emerging adults is associated with an increased risk of adverse outcomes. Similarly, pregnancies complicated by pregestational and gestational diabetes mellitus (GDM) carry a higher risk of complications. However, limited data exist on the intersection of these two high-risk conditions. Our objective was to establish the prevalence of teenage and emerging adult pregnancies complicated by diabetes in a population-based cohort and compare outcomes to pregnancies uncomplicated by diabetes, noting a background prevalence of GDM of 8.1% and pregestational diabetes of 1.2% across all age groups in the United States. Methods: This is a retrospective cohort study conducted in Olmsted County, Minnesota, USA. It includes female residents aged ≤21 years with a pregnancy ICD-10 code between January 1, 2013, and December 31, 2022. The main outcome measures assessed include maternal characteristics and maternal and fetal pregnancy outcomes. Results: A total of 1491 pregnancies in 1379 individuals were identified and included. In total, 68 (4.6%) pregnancies were complicated by diabetes: 51 (3.4%) with GDM and 17 (1.1%) with pregestational diabetes. In this study, pregnancies with diabetes had higher rates of adverse outcomes including cesarean delivery (GDM 29.4% vs. pregestational 60.0% vs. no diabetes 17.0%, P < 0.001), preeclampsia (GDM 15.7% vs. pregestational 40.0% vs. no diabetes 7.3%, P < 0.001), large-for-gestational-age neonates (GDM 13.7% vs. pre-existing 50.0% vs. no diabetes 5.8%, P < 0.001), and neonatal hypoglycemia (GDM 42.6% vs. pregestational 60.0% vs. no diabetes 13.3%, P < 0.001). Conclusions: The prevalence of pregestational diabetes in our teenage and emerging adult population is similar to that of the general pregnancy population; however, the prevalence of GDM is significantly lower. Overall, diabetes in teenage pregnancy is associated with an elevated risk of adverse maternal and neonatal outcomes. Future research should evaluate interventions aimed at reducing adverse pregnancy outcomes in this vulnerable population.

Introduction Trigeminal neuralgia is a debilitating facial pain condition characterized by recurrent, electric shock-like episodes within the trigeminal nerve distribution. While first-line treatment involves pharmacologic therapy, treatment options are limited for patients who are refractory or poor surgical candidates. Case Presentation We present a 75-year-old female with long-standing idiopathic trigeminal neuralgia refractory to combination anticonvulsant therapy and nerve block, with notable medication-related side effects. Management and Outcomes The patient underwent percutaneous cryoneurolysis targeting the maxillary (V2) and mandibular (V3) divisions of the trigeminal nerve under fluoroscopic guidance. She experienced immediate pain reduction and complete symptom resolution at a one-month follow-up with no complications. Conclusion This case highlights percutaneous cryoneurolysis as a minimally invasive treatment option for selected patients with refractory trigeminal neuralgia who are not candidates for open surgical intervention.

PURPOSE Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths worldwide. The higher incidence and earlier onset of HCC in sub-Saharan Africa suggest a potential role for a genetic predisposition. This study evaluated the association of TERT -rs2242652-(A), a variant linked to lower HCC risk, with HCC in populations from Ghana, Nigeria, and Cameroon, compared with a population from the United States. METHODS The study included 537 patients with HCC: United States (n = 348), Ghana (n = 79), Nigeria (n = 43), and Cameroon (n = 67). The control group had 2,872 cancer-free individuals: United States (n = 2,399), Ghana (n = 323), Nigeria (n = 85), and Cameroon (n = 65). Whole-exome sequencing was conducted using germline DNA, and data for TERT -rs2242652 were analyzed. Odds ratios (ORs) and 95% CIs were calculated using unconditional logistic regression. Chi-square tests assessed protective allele frequencies. RESULTS In the US cohort, TERT -rs2242652 was significantly associated with lower HCC risk (OR, 0.75 [95% CI, 0.58 to 0.96]; P = .02), with an allele frequency of 18.8% (15.4% in HCC cases v 19.3% in controls). In the combined sub-Saharan African population, no significant association was observed, but there was a trend toward decreased HCC risk (OR, 0.80 [95% CI, 0.53 to 1.22]; P = .29), with an allele frequency of 12.2% (10.6% in HCC cases v 12.9% in controls). Separate analyses of Ghanaian, Nigerian, and Cameroonian populations showed similar nonsignificant trends. The protective allele frequency in the combined African populations was significantly lower than in the US cohort ( P < .0001). CONCLUSION In sub-Saharan African populations, there was a lower frequency of the HCC protective allele TERT -rs2242652 compared with European Americans. These findings underscore the importance of multiethnic genetic studies in understanding population differences in HCC risk and developing prevention strategies.

Introduction Craniofacial hyperplasia is a disorder where the face and head do not fully develop. This leads to difficulties in airway management in those undergoing general anesthesia (GA), requiring consideration in anesthetic planning with GA and intubation versus approaches with regional/spinal anesthesia. Case Presentation A 54-year-old male (45 kg, 172.7 cm) presented for a penile implant insertion for severe erectile dysfunction following radical prostatectomy. He was classified as ASA physical status class III. Management and Outcomes Pertinent medical history included craniofacial hypoplasia from childhood surgical interventions and radiation for sinus cancer (rhabdomyosarcoma), moderate mitral regurgitation, mild tricuspid regurgitation, pulmonary hypertension, recurrent esophageal strictures, and anemia. Spinal anesthesia was selected over GA. Airway complications were avoided, and cardiopulmonary stability was preserved while maintaining adequate analgesic coverage. Conclusion Craniofacial hypoplasia patients require individualized anesthesia planning that anticipates complications. Spinal anesthesia can be used in these patients to avoid airway and hemodynamic complications.

Resistant hypertension (RH) is a high-risk phenotype characterized by blood pressure readings ≥130/80 mmHg despite maximally tolerated therapy with three antihypertensive agents, including a diuretic, or controlled blood pressure requiring four or more medications. The diagnosis of RH requires a structured evaluation that confirms accurate blood pressure measurement, excludes pseudoresistance—particularly nonadherence and white coat hypertension—and identifies secondary causes such as obstructive sleep apnea, primary aldosteronism, renovascular disease, pheochromocytoma, and Cushing syndrome. RH arises from overlapping mechanisms, including activation of the renin–angiotensin–aldosterone system (RAAS), sympathetic overactivity, arterial stiffness, volume expansion, and immune-mediated pathways. Management begins with lifestyle modification and optimized triple therapy, followed by mineralocorticoid receptor antagonists as the preferred fourth-line treatment. Emerging pharmacological options, such as sodium–glucose cotransporter-2 (SGLT2) inhibitors, glucagon-like peptide-1 (GLP-1) receptor agonists, endothelin receptor antagonists, aldosterone synthase inhibitors, and angiotensin receptor and neprilysin inhibitors (ARNIs), offer additional therapeutic potential; meanwhile, device-based interventions, including renal denervation and baroreflex activation therapy, have shown sustained blood pressure reductions in selected patients. Future directions highlight precision medicine, digital health technologies, and artificial intelligence as methods to improve diagnosis, guide individualized therapy, and enhance long-term blood pressure control.

Abstract Object Transdermal biosensors may provide an alternative to conventional blood-based biomarker measurement. Our purpose was to determine the binary correlation between transdermal (Infrasensor™; RCE, Inc, Carlsbad, CA) and conventional blood-based measurements. Methods This was a secondary analysis from a previously published observational cardiac troponin I (cTnI) study performed to establish the upper reference level of cTnI, at 10 US hospitals. After obtaining informed consent, 2 cohorts of patients were enrolled: 1) those who completed a health assessment questionnaire and appeared healthy, and 2) those with a known elevated cTnI per the local hospital standard assay. All blood lab analyses were performed at the University of Maryland Medical Center, Baltimore, MD. Normal was defined as cTnI <53.48 ng/L (male) or 34.11 ng/L (female) using the Siemens Atellica IM assay (Siemens Medical Solutions, Mountain View, CA), NT-proBNP <450 pg/mL (>75 years) or <124 pg/mL (<75 years), creatinine >1.17 mg/dL (male) or >0.95 mg/dL (female), and HbA1c <6.4%. The Infrasensor was placed on the patient’s wrist for measurement and blood drawn for analysis at approximately the same time. Results Of 840 enrolled patients, the median (IQR) age was 46 (30,57), 416 (49.5%) were female, 10.36% Hispanic, 6.7% Asian, 12.9% African American, and 69.1% White. Elevated lab tests were 102 hscTnI’s, 156 NTproBNP’s, 37 HbA1C’s, and 163 creatinine’s. Significant binary correlations were found between all transdermal signals and the corresponding lab blood levels Conclusion Infrasensor transcutaneous measurement demonstrates similar results as that obtained from blood testing in the central laboratory. Capsule The Infrasensor (RCE, Inc, Carlsbad, CA, USA) is rapid point of care transcutaneous biomarker measurement device. This study evaluated its ability to provide qualitative results for troponin I, NTproBNP, creatinine, and HbA1c levels in 840 patients. Significant correlations were found between all transdermal signals and the corresponding binary lab blood levels.

Background: There is no consensus scoring system for staging and prognosis in hepatocellular carcinoma (HCC), which is the fourth leading cause of cancer-related mortality worldwide. Commonly used systems include the albumin–bilirubin (ALBI) score, the Barcelona staging classification (Barcelona Clinic Liver Cancer, BCLC), the Model for End-Stage Liver Disease (MELD), and the model to estimate survival in ambulatory HCC patients (MESIAH). Liver secretion of pseudocholinesterase (PCHE) has been linked to liver function but is poorly studied in the natural history of HCC. We evaluated whether serum PCHE level predicts HCC mortality and whether it enhances existing scoring systems. Methods: We conducted a retrospective cohort study of individuals diagnosed with HCC. We collected variables including PCHE level, clinical data used in scoring systems, and time to mortality or liver transplant. We then analyzed the association between these variables and survival using Kaplan–Meier curves, Cox proportional hazards regression models, receiver operating characteristic (ROC) curves, and area under the curve (AUC) calculations. Results: We identified 420 individuals with HCC who were tested for PCHE levels, with a follow-up time of more than 20 years. There was a strong inverse relationship between PCHE level and overall survival, with the lowest quartile having high mortality and poor outcomes. Low PCHE level was associated with hepatitis C virus (HCV) infection, vascular invasion, poor liver function, and a high likelihood of liver transplant. In contrast, the highest quartile was associated with metabolic dysfunction–associated steatotic liver disease (MASLD) as the underlying cause. Compared with validated scoring systems, ALBI, BCLC, MELD 3.0, and MESIAH, the PCHE level was an independent predictor of mortality. PCHE levels could predict 3-month survival as well as or better than the other scoring systems, with an AUC of 0.74. PCHE level could also predict mortality related to hepatectomy. The addition of PCHE level to MESIAH and ALBI scoring systems could further improve the ability to predict overall mortality in HCC. Conclusions: PCHE is a reliable stand-alone biomarker of HCC prognosis. It is an independent predictor of mortality and can improve the accuracy of existing scoring systems. Improved risk stratification could improve outcomes by informing treatment decisions regarding hepatectomy or other interventions.

Traumatic brain injury (TBI) is one of the leading causes of death and neurological disability worldwide. The search for biomarkers that indicate TBI severity and prognosis with greater accuracy is ongoing. This study aimed to evaluate the significance of several neuroinflammatory cytokines and chemokines, assessing their potential as biomarkers in pediatric TBI (pTBI). This was an exploratory analysis of inflammatory cytokines and chemokines measured in a subset of 26 children aged 0–18 years with TBI and 21 controls. TBI severity was determined by GCS. The functional outcome was measured via the GOS-E score at 6 weeks and 3, 6, 9, and 12 months post-injury. Serum samples were analyzed for ICAM-1, VCAM-1, SAA, CRP, IFN-g, IL-10, IL-12p70, IL-13, IL-1b, IL-2, IL-4, IL-6, IL-8, TNF-a, TNF-b, eotaxin, eotaxin-3, IP-10, MCP-1, MCP-4, MDC, MIP-1a, MIP-1b and TARC. Levels of IL-6, IL-10, IL-13, IL-16, MDC, and GM-CSF were increased, and IFN-γ, IL-5, IL-8, and eotaxin-3 were decreased at enrollment when compared with controls. Elevated IL-6 and IL-10 at enrollment were associated with severe TBI (AUC of 1, p = 0.0002 and p = <0.0001, respectively). IL-6, IL-10, IL-16, and TNF-β at enrollment and IL-5 at 24 h were elevated in children with unfavorable outcomes, with an AUC > 0.8, suggesting biomarker potential. Our data indicate that several cytokines and chemokines measured after TBI may aid in the assessment of pTBI severity and prognosis. IL-6, IL-10, and IL-16 may show potential as biomarkers for pTBI severity and outcomes.
