Adverse event (AE)-related costs represent an important component of economic models for cancer care. However, since previous studies mostly focused on specific AEs, treatments, or cancer types, limited information is currently available. Therefore, this study assessed the incremental healthcare costs associated with a large number of AEs among patients diagnosed with some of the most prevalent types of cancer. Data were obtained from a large US claims database. Adult patients were included if diagnosed with and treated for one of the following cancer types: breast, digestive organs and peritoneum, genitourinary organs (including bladder and ovary and other uterine adnexa), lung, lymphatic and hematopoietic tissue, and skin...

Catecholamine and serotonin are biogenic amines (BAs) that serve as neurotransmitters and play an important role in the regulation of cardinal functions that are mainly altered during central nervous system (CNS) infections. A total 92 samples of cerebrospinal fluid (CSF) were classified into 4 groups based on their etiology. In these samples, BAs/neurotransmitters i.e., dopamine (DA), 3,4-dihydroxyphenylacetic acid (DOPAC), homovanillic acid (HVA), and 5-hydroxyindoleacetic acid (5HIAA) were detected and quantified by high performance liquid chromatography with electrochemical detection (HPLC-EC) to determine the neurophysiology of the CNS infections by bacteria ( Listeria monocytogenes (Lm) and Neisseria meningitidis (Nm)) and herpes simplex virus (HSV)...

Rabies is a fatal disease of all mammals causing almost 60,000 human deaths every year. To date, there is no effective treatment of clinical rabies once the symptoms appear. Here, we describe the promising effect of combination therapy composed of molecules that target replication of the rabies virus (RV) at different stages of life cycle and molecules that inhibit some pathways of the innate host immune response accompanied by a blood-brain barrier opener on the outcome of RV infection. The study reports statistically significant extension of survival of mice treated with the drug cocktail containing T-705, ribavirin, interferon α/β, caspase-1 inhibitor, TNF-α inhibitor, MAPKs inhibitor and HRIG compared to the survival of mice in the virus control group (p = 0...

The neurotropic protozoan Toxoplasma gondii is the second leading cause of death due to foodborne illness in the US, and has been designated as one of five neglected parasitic infections by the Center for Disease Control and Prevention. Currently, no treatment options exist for the chronic dormant-phase Toxoplasma infection in the central nervous system (CNS). T. gondii cathepsin L (TgCPL) has recently been implicated as a novel viable target for the treatment of chronic toxoplasmosis. In this study, we report the first body of SAR work aimed at developing potent inhibitors of TgCPL with selectivity vs the human cathepsin L...

This paper discusses the current evidence from animal and human studies for a central role of inflammation in schizophrenia. In animal models, pre- or perinatal elicitation of the immune response may increase immune reactivity throughout life, and similar findings have been described in humans. Levels of pro-inflammatory markers, such as cytokines, have been found to be increased in the blood and cerebrospinal fluid of patients with schizophrenia. Numerous epidemiological and clinical studies have provided evidence that various infectious agents are risk factors for schizophrenia and other psychoses...

Leishmaniasis is a vector-borne zoonotic disease that shows different clinical features like cutaneous, mucocutaneous, visceral and viscerotropic forms. The protocols used in the treatment of leishmaniasis are toxic and have many limitations during administration. One of the limitations of treatment is the resistance against the protocols in practice. There is also a need to define new treatment options especially for resistant patients. Ex-vivo models using primary cell cultures may be a good source for evaluating new drug options in patients with antimony resistance, in addition to in-vitro and in-vivo studies...

Increasingly, ecoimmunology studies aim to use relevant pathogen exposure to examine the impacts of infection on physiological processes in wild animals. Alphaviruses are arthropod-borne, single-stranded RNA (ssRNA) viruses ("arboviruses") responsible for millions of cases of human illnesses each year. Buggy Creek virus (BCRV) is a unique alphavirus that is transmitted by a cimicid insect, the swallow bug, and is amplified in two avian species: the house sparrow (Passer domesticus) and the cliff swallow (Petrochelidon pyrrhonota)...

This is the first reported case of a Chiari 1 malformation in association with tuberculous (TB) meningitis. We present a case of a 23-year-old woman with a 2-week history nocturnal fever, vertigo, headache and projectile vomiting. She had nystagmus, scanning speech, bilateral papilloedema and ataxia. Cranial imaging showed a 10 mm tonsillar herniation. Posterior fossa decompression was done. Because the patient's gamut of symptoms was highly suspicious for a central nervous system infection, a lumbar tap was done which revealed TB meningitis...

Background: Toxoplasmosis is an infectious disease caused by protozoan parasite called Toxoplasma gondii . Toxoplasma gondii is an intracellular protozoan parasite belong to phylum Apicomplexa, is an obligate parasite in mammals. The active proliferating trophozoites or tachyzoites are usually seen in the acute stage of infection, while the resting bradyzoites formed tissue cysts are primary found in muscle and brain. Human infection occurs mainly by ingesting food or water contaminated with oocyst or eating an undercook meat containing tissue cyst...

Burkholderia multivorans is a member of the Burkholderia cepacia complex. Although it is usually associated with infections in patients with cystic fibrosis, chronic granulomatous disease, and immunosuppression, central nervous infections are not commonly reported. Moreover, management of these infections is difficult due to multiple mechanisms of bacterial resistance to antimicrobial agents. We report a 55-year-old-man who developed Burkholderia multivorans meningitis after two episodes of central line-associated bloodstream infections...

The Zika virus (ZIKV) epidemic is associated with fetal brain lesions and other serious birth defects classified as congenital ZIKV syndrome. Postnatal ZIKV infection in infants and children has been reported; however, data on brain anatomy, function, and behavioral outcomes following infection are absent. We show that postnatal ZIKV infection of infant rhesus macaques (RMs) results in persistent structural and functional alterations of the central nervous system compared to age-matched controls. We demonstrate ZIKV lymphoid tropism and neurotropism in infant RMs and histopathologic abnormalities in the peripheral and central nervous systems including inflammatory infiltrates, astrogliosis, and Wallerian degeneration...
