Cerebrospinal fluid (CSF) biological markers may be of valuable help in the diagnosis of dementia. The aim of the present study was to evaluate CSF levels of 13 potential biomarkers in patients with Alzheimer’s disease (AD), frontotemporal lobe dementia, alcohol dementia, major depression and control patients without any neuropsychiatric disease. The study was performed using β-amyloid 1–42 (Aβ42), total tau and phosphorylated tau-181 (P-tau181) as core markers. The ratio P-tau181/Aβ42 could significantly distinguish AD patients from all other diagnostic subgroups. CSF levels of 5 growth factors (HGF, GDNF, VEGF, BDNF, FGF-2) and 3 cytokines/chemokines (TNF-α, TGF-β₁, MIP-1α) did not significantly differentiate between the studied groups. However, depending on the degree of neurodegeneration (as expressed by the ratio P-tau181/Aβ42), patients with AD displayed significantly increased CSF levels of nerve growth factor (NGF) as compared to healthy controls. CSF levels of monocyte chemoattractant protein 1 (MCP-1) were found to be significantly increased with age in all groups but did not distinguish AD patients from healthy controls. The results confirmed the suitability of the ratio P-tau181/Aβ42 for the diagnosis of AD, while CSF levels of NGF and MCP-1 are less specific and reliable for AD. It is suggested that the increase in NGF depends on the extent of neurodegeneration of the AD type and the increase in MCP-1 on age.

Anesthesia in the Republic of Zambia is a highly under-developed and under-resourced medical specialty.

Unenhanced diagnostic MR imaging (DWIBS mammography), with an NPV of 0.92 and an acquisition time of less than 7 minutes, could help exclude malignancy in women with suspicious x-ray screening mammograms. The method has the potential to reduce unnecessary invasive procedures and emotional distress for breast cancer screening participants if it is used as a complement after the regular screening clarification procedure.

Our results suggest that a high level of job satisfaction in anaesthetists correlates with interesting work demands and the opportunity to contribute skills and ideas. To improve job satisfaction, more attention should be paid to improving working conditions, including control over decision-making, and allowing anaesthetists to have more influence on their own work pace and work schedule.

In surgical patients hypoxia, high cardiac filling pressures, a greater degree of physiologic derangement at admission, and the presence of SIRS and sepsis are independent risk factors for the development of TA.
