Background And Objective: Ambulatory blood pressure monitoring (ABPM) requires automatic measurement and the use of a validated device, according to current guidelines and international standardization. The TM-2441 (A&D Co. Ltd, Tokyo, Japan) ABPM device is small, lightweight, and suitable for use in ambulatory settings. It was validated against the ISO 81060-2:2013 standard in the general population. This study investigated the reliability of the ABPM device for patients with type 2 diabetes.

Methods: Individuals aged more than 12 years affected with type 2 diabetes were recruited by our outpatient clinic. The blood pressure assessment was performed using the opposite limb simultaneous measurement according to the updated ISO 81060-2:2018.

Results: Forty-five subjects were included in the clinical investigation. The mean difference between blood pressure values measured by the TM-2441 ABPM device and the reference sphygmomanometer was within limits allowed by the ISO standard. Bland-Altman plots of the measurements and differences between the values obtained from the study device and those from the reference device showed no systematic variations in error. It was not possible to perform a stress test in most patients due to refusal or poor physical condition.

Conclusion: The TM-2441 ABPM device fulfilled all the requirements of the ISO standard for ambulatory testing not only in a general population but also in the subgroup of subjects with type 2 diabetes.

Rationale: Established coronary artery disease (CAD) patients are at increased risk for recurrence of cardiovascular events and mortality due to non-attainment of recommended risk factor control targets.

Objective: We aimed to evaluate the attainment of treatment targets for risk factor control among CAD patients as recommended in the Indonesian CVD prevention guidelines.

Methods: Patients were consecutively recruited from the Makassar Cardiac Center at Wahidin Sudirohusodo Hospital, Indonesia.

This study investigated the predictive value of combining peripheral blood indicators with procalcitonin clearance rate (PCTc) to assess mortality risk in cancer patients with sepsis, aiming to develop a more sensitive and specific clinical tool. A retrospective analysis was conducted on 393 cancer patients with sepsis admitted to South China Hospital of Shenzhen University from January 2019 to January 2024. Collected data included clinical demographics, laboratory indicators such as white blood cell count, neutrophil count (NEUT), platelet count (PLT), lymphocyte count (LYC), C-reactive protein, procalcitonin (PCT), alanine aminotransferase, and the ratio of arterial oxygen partial pressure to inspired oxygen fraction, as well as functional scores like Acute Physiology and Chronic Health Evaluation II (APACHE II) and Sequential Organ Failure Assessment.

African-American women have a maternal mortality rate approximately three times higher than European-American women. This is partially due to hypertensive disorders of pregnancy, including preeclampsia. Fetal high-risk genotype increases preeclampsia risk, although mechanisms remain elusive.

Primary aldosteronism (PA) is a common cause of secondary hypertension, with familial hyperaldosteronism (FH) contributing to a lesser number of cases. FH type IV, a rare subtype, has hardly been reported as a subtype of PA cases. We present a case of a 27-year-old female who presented to the emergency department with circumoral tingling and numbness.
