Article Synopsis
  • Lung cancer remains the top cause of cancer-related deaths globally, with this study focusing on the impacts of stage IV non-small cell lung cancer (NSCLC) in Mexico's healthcare system.
  • The research involved 188 patients diagnosed with stage IV NSCLC, analyzing treatments and outcomes at various healthcare centers while also assessing economic factors like treatment costs and productivity losses among patients and caregivers.
  • Findings indicated high treatment costs, with public sector costs averaging MXN1,001,579 per patient and private sector costs around MXN2,140,604, alongside significant productivity losses for both patients (up to 335 days/year) and caregivers (13-30 days/year).

Children and adolescents in foster care include many of the most severely traumatized victims of child abuse and neglect. They deserve the best possible care and treatment, yet their outcomes remain poor. The persistence of poor outcomes for youth in foster care reflects challenges of psychiatric diagnostic formulation and of service system design/access, both areas in which child and adolescent psychiatrists have a key role to improve care and outcomes.

Effective partnerships can profoundly impact outcomes for youth with behavioral health concerns. Partnerships occur at multiple levels - at the individual, organizational, state, and national levels. The Systems of Care (SOC) framework helps to conceptualize and articulate the skills necessary for forming partnerships in youth's mental health.

Introduction: Agitation in children and adolescents in the emergency department (ED) can be dangerous and distressing for patients, family and staff. We present consensus guidelines for management of agitation among pediatric patients in the ED, including non-pharmacologic methods and the use of immediate and as-needed medications.

Methods: Using the Delphi method of consensus, a workgroup comprised of 17 experts in emergency child and adolescent psychiatry and psychopharmacology from the the American Association for Emergency Psychiatry and the American Academy of Child and Adolescent Psychiatry Emergency Child Psychiatry Committee sought to create consensus guidelines for the management of acute agitation in children and adolescents in the ED.

Washout CT is commonly used to evaluate indeterminate adrenal nodules, although its diagnostic performance is poorly established in true adrenal incidentalomas. The purpose of this study was to compare, in patients without a known malignancy history, the prevalence of malignancy for incidental adrenal nodules with unenhanced attenuation more than 10 HU that do and do not show absolute washout of 60% or more, thereby determining the diagnostic performance of washout CT for differentiating benign from malignant incidental adrenal nodules. This retrospective six-institution study included 299 patients (mean age, 57.

Objectives: To evaluate the T2-weighted (T2W) MRI calculator to differentiate adrenal pheochromocytoma from lipid-poor adrenal adenoma.

Methods: Twenty-nine consecutive pheochromocytomas resected between 2010 and 2019 were compared to 23 consecutive lipid-poor adrenal adenomas. Three blinded radiologists (R1, R2, R3) subjectively evaluated T2W signal intensity and heterogeneity and extracted T2W signal intensity ratio (SIR) and entropy.

Objective: To compare diagnostic accuracy of washout (WO)-CT to chemical shift (CS)-MRI + T2W adrenal MRI Calculator (T2W-Calculator) to diagnose adrenal adenoma in indeterminate adrenal masses.

Methods: This retrospective, cross-sectional, non-inferiority study evaluated 40 consecutive indeterminate adrenal masses; each with WO-CT and MRI. Two blinded radiologists independently evaluated in mixed order: pre-contrast attenuation (Hounsfield Units, HU) and absolute WO ([Peak.

Objective: Impairing emotional outbursts, defined by extreme anger or distress in response to relatively ordinary frustrations and disappointments, impact all mental health care systems, emergency departments, schools, and juvenile justice programs. However, the prevalence, outcome, and impact of outbursts are difficult to quantify because they are transdiagnostic and not explicitly defined by current diagnostic nosology. Research variably addresses outbursts under the rubrics of tantrums, anger, irritability, aggression, rage attacks, or emotional and behavioral dysregulation.

Objectives: Agitation and restraint among pediatric psychiatric patients are a frequent, yet little studied, source of morbidity and, rarely, mortality in the emergency department (ED). This study examined agitation and restraint among youth patients in a specialized pediatric psychiatric ED, considering clinical and sociodemographic characteristics of those who required restraint to determine the clinical correlates of agitation and restraint in this population.

Methods: This descriptive study was a 6-year retrospective chart review of all patients restrained for acute agitation.

Objective: To compare MR-imaging features in benign lipid-rich and lipid-poor adrenal adenomas.

Materials And Methods: With institutional review board approval, we compared 23 consecutive lipid-poor adenomas (chemical shift [CS] signal intensity [SI] index < 16.5%) imaged with MRI to 29 consecutive lipid-rich adenomas (CS-SI index ≥ 16.

Objectives: Stereotactic Ablative Radiotherapy (SABR) has shown high rates of local control and prolonged survival in early-stage non-small cell lung cancer (NSCLC), though its role in oligometastatic disease is undefined. This study aimed to evaluate SABR as a local consolidative therapy (LCT) in oligometastatic NSCLC patients.

Methods: In this prospective, single-arm phase 2 trial, we sought to evaluate SABR in patients with stage IV NSCLC, with ≤ five lesions, including the primary tumor.

Background: Merkel cell carcinoma (MCC) is an aggressive malignancy, associated with poor outcomes in patients with metastatic disease (mMCC). Management has been dramatically altered as a result of incorporating immune checkpoint blockade agents. MCC data from Latin America (LATAM) come from case-series or individual records.

Failure to adjust doses may contribute to adverse events. We evaluated the effectiveness of providing the estimated glomerular filtration rate on appropriateness of dosing for antimicrobials. The approach increased appropriateness of dosing from 33.

Importance: Because of socioeconomic factors, many patients with advanced non-small cell lung cancer (NSCLC) do not receive immunotherapy in the first-line setting. It is unknown if the combination of immunotherapy with chemotherapy can provide clinical benefits in immunotherapy-naive patients with disease progression after treatment with platinum-based chemotherapy.

Objective: To evaluate the safety and efficacy of the combination of pembrolizumab plus docetaxel in patients with previously treated advanced NSCLC following platinum-based chemotherapy regardless of EGFR variants or programmed cell death ligand 1 status.

Lung cancer is a major global public health problem, yet the disease is highly stigmatized, which impairs the opportunities to get optimal treatment for these patients. Globally, as well as locally in Mexico, lung cancer is the main cause of cancer-related deaths. Despite this, it is the only one among the five deadliest cancers in Mexico which is not covered by Popular Health Insurance.
