REVIEW
Ruth Feldman, Marian J Bakermans-Kranenburg
In non-human mammals mothering is hormone-dependent, with crucial roles for oxytocin and prolactin. While human parenting is not hormone-dependent, hormonal changes in oxytocin, vasopressin, prolactin, testosterone, and cortisol prime and accompany the expression of parenting. In the following we focus on oxytocin (OT) as a key hormone in human parenting. OT is a nine-amino-acid neuropeptide hormone which evolved from the ancient vasotocin molecule approximately 650 MYO. OT is implicated in sociality across vertebrate evolution and substantial research has pinpointed its role in birth, lactation, and maternal care in mammals...

Fungal infections of the central nervous system (CNS) frequently occur in immunosuppressed patients. Here, we describe the case of an immunocompetent 64-year-old man who presented with diplopia, right-sided hemiparesis, and a mild headache after cleaning and replacing nesting boxes of wild birds during the preceding months. Lumbar puncture revealed pleocytosis, elevated protein, and lactate levels in the cerebrospinal fluid (CSF). Initial imaging showed ischemia in the left thalamus and an enlargement of the sellar region...

Multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) are inflammatory diseases of the central nervous system. Although several studies have characterized the metabolome in the cerebrospinal fluid (CSF) from MS and NMOSD patients, comparative analyses between them and between the relapse and the remission of each disease have not been performed. Both univariate and multivariate analyses were used to compare 1H-NMR spectra of CSF from MS, NMOSD, and healthy controls (HCs). The statistical analysis showed alterations of eight metabolites that were dependent on the disease...

OBJECTIVE: Primary central nervous system (CNS) lymphoma is an aggressive and fatal extranodal non-Hodgkin lymphoma (NHL) jailed in CNS at initial diagnosis. Its prognosis is poor and the disease has a fatal outcome when compared with systemic NHL. A few baseline risk stratification scoring systems have been suggested to estimate the prognosis mainly based on serum lactate dehydrogenase (LDH) level, age, Karnofsky performance score (KPS), involvement of deep brain structures (DBS) and cerebrospinal fluid protein concentration...

BACKGROUND: Immunoparalysis was observed in both patients with cancer and sepsis. In cancer patients, Cytotoxic T lymphocyte antigen-4 and programmed cell death protein 1/programmed death-ligand 1 axis are two key components of immunoparalysis. Several emerging therapies against these two axes gained significant clinical benefit. In severe sepsis patients, immunoparalysis was known as compensatory anti-inflammatory response syndrome and this has been suggested as an important cause of death in patients with sepsis...

Epithelial injury has been proposed to be the initiating factor in the pathogenesis of idiopathic pulmonary fibrosis (IPF). We have shown previously that heparan sulfate (HS) 6-O-endosulfatase 2 (Sulf2) is overexpressed in the hyperplastic type II alveolar epithelial cells (AECs) in the IPF lungs. By removing 6-O-sulfates from specific HS intra-chain sites, Sulf2 modulates the functions of many growth factors and cytokines. In this study we hypothesized that Sulf2 plays a regulatory role in alveolar epithelial injury and repair, using the murine bleomycin model...

INTRODUCTION: Central nervous system (CNS) involvement in acute lymphoblastic leukemia (ALL) is diagnosed traditionally by cytopathology (CP) of the cerebrospinal fluid (CSF). Role of flow cytometry (FC) to diagnose CNS involvement has not been extensively investigated. METHODS: We aimed to detect CNS involvement in 42 ALL patients (33 B-ALL, nine T-ALL) at diagnosis by FC and comparing it with CP and to correlate it with known risk factors for CNS disease like Lactate dehydrogenase (LDH)...

Periparturient dairy cows experience impaired immune function, exhibited as a transient decrease in neutrophil function and neutropenia. This decrease in immune competence is associated with an increase in susceptibility to bacterial infections, including mastitis and metritis. Bovine granulocyte colony stimulating factor (bG-CSF) is an endogenous protein that enhances neutrophil bactericidal functions and increases the production of neutrophils from bone marrow precursors. Administration of pegbovigrastim (recombinant bG-CSF covalently bound to polyethylene glycol) around the time of calving has been shown to reduce the incidence of new clinical mastitis cases in a natural disease model system...

OBJECTIVE: Clinical neurological assessment is challenging for severe traumatic brain injury (TBI) patients in the acute setting. Waves of neurochemical abnormalities that follow TBI may serve as fluid biomarkers of neurological status. We assessed the cerebrospinal fluid (CSF) levels of glutamate, lactate, BDNF, and GDNF, to identify potential prognostic biomarkers of neurological outcome. METHODS: This cross-sectional study was carried out in a total of 20 consecutive patients (mean [SD] age, 29 [13] years; M/F, 9:1) with severe TBI Glasgow Coma Scale ≤ 8 and abnormal computed tomography scan on admission...

Despite recent studies examining the association between neurodegenerative diseases and mitochondrial dysfunction, there are not sufficient data on factors that influence cerebrospinal fluid (CSF) lactate levels. Thus, we investigated factors that affect CSF lactate levels in neurodegenerative diseases. We extracted laboratory findings, including CSF lactate, glucose, and protein levels, and demographic and background information, including age and gender, from the electronic medical records of patients with neurodegenerative diseases in order to explore factors that have an impact CSF lactate levels...

Lactate is a product of glycolysis by astrocytes and can be generated as a primary metabolic energy source by neurons. Lactate plays multifunctional role in human brain energy metabolism and cognitive function. However, no direct evidence demonstrated the link between lactate and cognition in normal condition. In the present study, concentrations of lactate in cerebrospinal fluid (CSF) and peripheral blood were measured to investigate the association of lactate with cognitive ability, which was assessed by Montreal Cognitive Assessment (MoCA), in 99 male Chinese subjects...

INTRODUCTION: During military deployment, the diagnosis and the management of acute bacterial meningitis can be problematic, as deployed Medical Treatment Facilities (MTFs) often have a limited laboratory diagnostic capability. However, French Role 2 and 3 MTFs have point-of-care (POC) testing to perform urinary (Multistix 10 SG strip) and blood (iSTAT handheld analyser) biochemical testing mentioned in AMedP8.5. The purpose of this study was to compare the accuracy of this urine test strip and of the iSTAT CHEM8 and CG4 cartridges with a standard hospital bench top analyser in order to determine if these POC devices have a potential role in the biochemical analysis of cerebrospinal fluid (CSF protein, CSF glucose and CSF lactate, respectively)...
