We report a case of a 33-year-old Sri Lankan man who presented with flaccid quadriparesis with brainstem signs and acute motor axonal polyneuropathy. MRI of the brain showed multiple abscesses with ring enhancement seen predominantly in the brainstem and upper cervical cord. The patient was initially treated with intravenous immunoglobulin, considering this to be a form of Guillain-Barré syndrome. Cerebrospinal fluid, however, showed lymphocytic pleocytosis with raised protein. Tests for Brucella, tuberculosis, toxoplasmosis, syphilis and HIV were negative. Chest X-ray revealed a cavity in the left lung, which, on bronchoscopy, showed a collection of purulent secretions. Culture of these secretions grew Burkholderia pseudomallei. The patient was treated with two courses of intravenous antibiotics, with resultant radiological improvement; however, with significant morbidity.

Tissue-resident memory T (TRM) cells possess unique abilities to migrate, establish themselves in tissues, and monitor peripheral tissues without circulating. They are crucial in providing long-lasting and local immune protection against surface infections. TRMs demonstrate distinct phenotypic and functional characteristics compared to central memory T (Tcm) cells and effector memory T (Tem) cells.

Objective: The role of adiponectin (APN) in regulating inflammation is well recognized in metabolic disease, but the dysregulation of APN in lower respiratory tract infection (LRTI) remains controversial. We aimed to measure APN and its signaling receptors, adiponectin receptor (AdipoR), in peripheral blood mononuclear cells (PBMCs) from LRTI patients to explore their potential roles in the LRTI process.
Methods: A total of 99 LRTI patients from the Second Xiangya Hospital of Central South University were categorized into acute (n=35) and non-acute (n=64), and non-severe (n=62) and severe (n=37) groups.

HIV-associated neurocognitive disorder (HAND) is a complex neurological complication resulting from human immunodeficiency virus (HIV) infection, affecting about 50% of individuals with HIV and significantly diminishing their quality of life. HAND includes a variety of cognitive, motor, and behavioral disorders, severely impacting patients' quality of life and social functioning. Although combination antiretroviral therapy (cART) has greatly improved the prognosis for HIV patients, the incidence of HAND remains high, underscoring the urgent need to better understand its pathological mechanisms and develop early diagnostic methods.
