Sedation is a controllable level of medication depression of consciousness during which protective reflexes, adequate breathing, and responsiveness to physical stimuli and verbal commands are retained A number of physical and psychological factors affect the psyche of patients in the intensive care unit. Central nervous system (CNS) is a primary target of action of anesthetics and analgesics, and the bi-spectral index reflects the level of sedation of CNS, regardless of what drug caused sedation. The aim of this study was to use volatile anesthetics sevoflurane and isoflurane in children for sedation in the intensive care unit. Constant use of the inhalation route of administration helps to maintain the desired level of sedation depth for the required period of time in patients who are on long-term sedation and is practical for correction.

Necrotizing enterocolitis (NEC) is a devastating disease of the neonatal gastrointestinal tract. Volatile organic compounds (VOCs), odoriferous compounds released as a byproduct of bacterial metabolism, can be used as a proxy for gut health. We hypothesized that patients with NEC would have different microbial profiles and elicit different VOC signatures as assessed by gas chromatography/mass spectrometry (GC/MS) or an electronic nose compared to controls.

Hepatitis B (Hep B) remains a critical public health issue globally, particularly in Tibet, where vaccination rates and influencing factors among college students are yet understudied. This study applies a cross-sectional design to investigate the Hep B vaccination rate among 1,126 college students in Tibet and utilizes the expanded theory of planned behavior (ETPB) to identify vaccination behavior intention (BI) and vaccination behavior (VB). Stratified cluster sampling across three universities was used to assess behavioral attitudes (BA), subjective norms (SN), perceived behavioral control (PBC), past vaccination history (PVH) and vaccination knowledge (VK), and used structural equation modeling (SEM) for model validation and multi-group comparison.

In 2023, a breast cancer risk assessment and a subsequent positive test for the BRCA-2 genetic mutation brought me to the uncomfortable intersection of a longstanding career as an advocate for high-quality medical evidence to support shared patient-provider decision making and a new role as a high-risk patient. My search for studies of available risk-management options revealed that the most commonly recommended approach for women with a ⩾20% lifetime breast cancer risk, intensive screening including annual mammography and/or magnetic resonance imaging beginning at age 25-40 years, was supported only by cancer-detection statistics, with almost no evidence on patient-centered outcomes-mortality, physical and psychological morbidity, or quality of life-compared with standard screening or a surgical alternative, bilateral risk-reducing mastectomy. In this commentary, I explore parallels between the use of the intensive screening protocol and another longstanding women's health recommendation based on limited evidence, the use of hormone therapy (HT) for postmenopausal chronic disease prevention, which was sharply curtailed after the publication of the groundbreaking Women's Health Initiative trial in 2002.
