The genus is endemic to Mexico with a geographical distribution along the Sierra Madre Oriental, the Trans Mexican Volcanic Belt and the Sierra de Juárez. The recent use of molecular tools has shown that Mexico's amphibian diversity is highly underestimated, including a large number of cryptic, unnamed species. has 18 described species including terrestrial, arboreal and cave-dwelling species. In previous molecular studies, the presence of multiple undescribed species was evident. We present a phylogenetic hypothesis based on mitochondrial data, which includes all described species and six undescribed taxa. Based on the morphological analyses and, when available, combined with molecular data, we describe five new species of the genus; sp. nov., sp. nov., sp. nov., sp. nov. and sp. nov. In addition, we redescribe two others: and , and provide a comparable account of one additional sympatric congener. This increases the number of species in the genus to 23, which represent a considerable component of Mexican plethodontid richness.

Individual on Death Row Receiving Electroconvulsive Therapy (ECT) for Catatonia: A Case Report.
J ECT

Department of Psychiatry and Health Behavior, Medical College of Georgia at Augusta University, Augusta, GA.
Electroconvulsive therapy (ECT) is underused, logistically challenging for those who are justice-involved, and laced with ethical problems for those on death row. Herein we describe a case of a man without history of long-standing psychiatric illness who, after more than 15 years on death row, was hospitalized for altered mental status. After medical stabilization, the altered mental status persisted.

Faculty of Sport Sciences, Universidad Europea de Madrid.
Objectives: The effects of acute physical exercise in patients with resistant hypertension remain largely unexplored compared with hypertensive patients in general. We assessed the short-term effects of acute moderate-intensity (MICE) and high-intensity interval exercise (HIIE) on the clinic (BP) and 24-h ambulatory blood pressure (ABP) of patients with resistant hypertension.
Methods: Using a crossover randomized controlled design, 10 participants (56 ± 7 years) with resistant hypertension performed three experimental sessions: MICE, HIIE, and control.
Objective: The oxidative balance score (OBS) has emerged as a novel marker for assessing oxidative stress status. This study aimed to investigate the association of OBS with systolic blood pressure (SBP), diastolic blood pressure (DBP), all-cause, and cardiovascular disease mortality in hypertensive patients.
Methods: We conducted an analysis of data from 7602 hypertensive patients from the National Health and Nutrition Examination Survey (NHANES) 2005-2018.
Participation interest and completion of home blood pressure measurements with mailed devices in adults with and without hypertension.

November 2024
Robert Koch Institute, Department of Epidemiology and Health Monitoring.
Objectives: Home blood pressure monitoring (HBPM) is valuable for the detection and monitoring of hypertension. Despite logistical advantages, HBPM has not yet been used in national blood pressure (BP) surveys. We investigated randomly selected adults' willingness to participate in an HBPM study (attitude survey) and piloted this approach (feasibility study).
