Background: In Cameroon, like in many other resource-limited countries, data generated by health settings including morbidity and mortality parameters are not always uniform. In the absence of a national guideline necessary for the standardization and harmonization of data, precision of data required for effective decision-making is therefore not guaranteed. The objective of the present study was to assess the reporting style of morbidity and mortality data in healthcare settings.

Background: The World Professional Association for Transgender Health guidelines Standards of Care 8 draw on ethical arguments based on individual autonomy, to argue that healthcare and other professionals should be advocates for trans people. Such guidelines presume the presence of medical services for trans people and a degree of consensus on medical ethics. Very little is known, however, about the ethical challenges associated with both providing and accessing trans healthcare, including gender affirmation, in the Global South.

Purpose: It was noticed that anterior choroidal artery (AChoA) aneurysms appear to rupture at relatively smaller sizes compared with aneurysms in other intracranial locations, based on anecdotal clinical experience. We therefore aimed to compare ruptured AChoA aneurysms with other ruptured aneurysms in other intracranial locations, pertaining to aneurysm dimensions. This may help in finding out if the rupture risk stratification, based on the amalgamation of aneurysms of multiple locations in one group, precisely estimates aneurysm rupture risk.

January 2025

Mechanical Engineering Department, Tianjin University, No. 135, Yaguan Road, Haihe Education Park, Jinnan District, Tianjin City, 300350, China.

The use of AR technology in image-guided neurosurgery enables visualization of lesions that are concealed deep within the brain. Accurate AR registration is required to precisely match virtual lesions with anatomical structures displayed under a microscope. The purpose of this work was to develop a real-time augmented surgical navigation system using contactless line-structured light registration, microscope calibration, and visible optical tracking.

Like children, adult patients with active or abandoned epicardial pacing leads are also at risk of developing life-threatening cardiac ischemia due to mechanical compression of the coronary arteries. As this complication is amenable to surgical removal, these patients require periodic evaluation for myocardial ischemia even if they are asymptomatic.

With the development of molecular pharmacognosy, the advantages of DNA molecular markers in the identification of original plants of Chinese medicinal materials are becoming increasingly significant. To compensate for the limitations of existing markers in the quality supervision of Chinese medicinal materials, our team has independently designed a new molecular marker named DNA signature sequence(DSS). This marker is a nucleotide sequence that only appears in a specific taxonomic unit, with a length of 40 bp and high identification accuracy.

Sichuan Provincial Engineering Research Center of Formation Principle and Quality Evaluation of Genuine Medicinal Materials, Sichuan Engineering Technology Research Center of Genuine Regional Drug, Translational Chinese Medicine Key Laboratory of Sichuan Province, Key Laboratory of Biological Evaluation of TCM Quality of the State Administration of Traditional Chinese Medicine, Sichuan Institute for Translational Chinese Medicine Chengdu 610041, China.

Traditional Chinese medicine(TCM) resources refer to the total reserves of plants, animals, and minerals that can be used as raw materials of TCM(including Chinese medicial materials, TCM decoction pieces, TCM dispensing granules, traditional Chinese patent medicine, and TCM hospital preparation) and folk herbal medicine, which served as the material basis of inheritance, innovation, and development of TCM. In recent years, the sustainable utilization of TCM resources has received high attention and acquired a series of significant achievements in resource survey, quality evaluation, resource protection, innovative technology, and development and utilization, which effectively promoted the sustainable utilization of TCM resources and high-quality development of the TCM industry. The most urgent issue currently is to shift the focus of the research on the sustainable utilization of TCM resources from a sustainable utilization technology system to a sustainable utilization evaluation indicator system.

The immune-inflammatory responses on the hypothalamic-pituitary-adrenal axis and the neurovascular unit in perioperative neurocognitive disorder.

Exp Neurol

Department of Anesthesiology and Pain Medicine, Anesthesia and Pain Research Institute, Yonsei University College of Medicine, Seoul, Republic of Korea. Electronic address:

Perioperative neurocognitive disorders (PNDs) refer to a wide spectrum of cognitive impairment persisting days to even after a year postoperative with significant morbidity and mortality. However, despite much efforts involving perioperative managements, PNDs are still prevalent with no standard preventative and therapeutic strategy. To overcome PNDs, a better understanding of pathophysiology of PNDs is crucial and a large number of studies have proven that immune-inflammatory responses from surgical stress are involved in the abnormal activation of the hypothalamic-pituitary-adrenal (HPA) axis and destabilization of neurovascular unit (NVU) that lead to PNDs.

Patients with pulmonary fibrosis (PF) often experience long waits before getting a correct diagnosis, and this delay in reaching specialized care is associated with increased mortality, regardless of the severity of the disease. Early diagnosis and timely treatment of PF can potentially extend life expectancy and maintain a better quality of life. Crackles present in the recorded lung sounds may be crucial for the early diagnosis of PF.
