Certain medications can generate asthma symptoms, with the potential to cause considerable morbidity. This article focuses on the common drugs that have the potential to cause distinct respiratory reactions in asthmatics: aspirin and other nonsteroidal anti-inflammatory drugs, beta-blockers, and angiotensin-converting enzyme inhibitors. The means by which these medications can trigger asthma vary in terms of acuity of onset, severity, and the mechanisms involved. The general and most practical approach is avoidance and cautious use of these drugs in asthmatics. However, these classes of medications can exert a major role in the management of common and serious diseases. Fortunately, controller therapy for asthma and alternative or more selective medications for the treatment of these conditions are now available.

Objective: To explore risk factors for 1-year postoperative mortality and to identify its association with the Revised Cardiac Risk Index (RCRI).
Methods: This was a retrospective cohort study involving 54,933 patients aged 18 years and above who were surgically treated under general or regional anesthesia in a tertiary hospital in Singapore. Independent risk factors for 1-year postoperative mortality were identified by univariate Cox regression analysis.

Background: Cancer stem cells in human tumors have been defined by stem cell markers, embryonal signaling pathways and characteristic biology, ie., namely the ability to repopulate the proliferating population. However, even if these properties can be demonstrated within a tumor cell subpopulation, it does not mean that they are truly hierarchical stem cells because they could have been derived from the proliferating population in a reversible manner.

Claudins (CLDNs) play a crucial and indispensable role as fundamental components within the structure of tight junctions. Due to the distinct and unique distribution pattern exhibited by CLDNs in both normal and malignant tissues, these proteins have garnered significant attention as pivotal targets for systemic anti-cancer therapy and as noteworthy diagnostic markers. This review provides a comprehensive and detailed elucidation of the fundamental understanding surrounding CLDNs, their intricate expression patterns, the potential role they play in cancer diagnosis and therapeutic potentials; all encapsulated within a succinct summary of the cutting-edge advancements and the information derived from various clinical trials.

Introduction: Herpes encephalitis is known to affect patients undergoing brain radiotherapy, but early diagnosis and treatment, the foremost determinants of disease outcome, remain challenging in this patient population. This can be due to attribution of symptoms to the brain tumor and radiation side effects, as well as patients' atypical clinical presentation. Here we sought to highlight pearls and pitfalls in the clinical course and diagnostic workup which may facilitate timely diagnosis and improve disease outcome.

Electromyography (EMG) is increasingly used in stroke assessment research, with studies showing that EMG co-contraction (EMG-CC) of upper limb muscles can differentiate stroke patients from healthy individuals and correlates with clinical scales assessing motor function. This suggests that EMG-CC has potential for both assessing motor impairments and monitoring recovery in stroke patients. However, systematic reviews on EMG-CC's effectiveness in stroke assessment are lacking.
