    Abstract Most (90%) vitamin D synthesis occurs in the skin using sunlight (ultraviolet rays), and 10% is obtained through food. Vitamin D is an essential nutrient for skeletal growth and maintenance, cell proliferation and differentiation, and immune function. This study investigated whether maternal serum vitamin D concentrations induce maternofetal effects. Hematological analysis, serological changes, and precision fetal ultrasound findings were analyzed by maternal vitamin D concentration in gestational weeks 22-25 to ascertain direct effects on fetal growth. Bone density-vitamin D concentration correlation was analyzed. No hematologic or serological effect of maternal vitamin D concentration was detected; however, the sexually transmitted infection and cross-infection rates were inversely proportional to maternal vitamin D concentration. No significant correlation between vitamin D concentration and vertebral and femoral BMD was detected. For fetal growth, biparietal diameter, head circumference, abdominal circumference, femur length, and humerus length were analyzed. Humerus (

    Title translation Perception of the cancer diagnosis announcement in a university hospital setting in Ivory Coast: About 120 patients followed in oncology and onco-hematology services.
    Abstract Background: The diagnostic of cancer is generally associated with a psychological shock. Body's defense mechanisms and drugs cannot resolve emotional distress and symptoms of cancer. A need for psychosocial management of the African patient is necessary.
    Objectif: Study of perception of the cancer diagnosis announcement by Ivory Coast patients suffering of cancer.
    Patients and methods: This is a bicenter retrospective and cross-sectional study which aims at describing data over a period of seven (7) months (November 2017 to May 2018). This study took place in the haematology and oncology departments respectively in CHU of Yopougon and Treichville. Patient recruitment was carried out exhaustively. The data was collected using a standardized questionnaire, developed in the french language, which was given individually under the direction of the oncopsychiatrist investigator. The investigation required the presence of an interpreter for patients who did not speak French. This study exhibits sociodemographic, clinical, therapeutical and medico-psychosocial data. So, 120 patients were included.
    Results: Breast's cancer was frequent (61%) and found at advanced stages (71%). Incurability and death's idea were 0.8% and 3.3%, respectively. Diagnostic announcement was good in 95% cases, but patients developed sadness (63.3%), denial (10%) and idea of suicide (3.4%). The psychosocial life of patients was affected by depressed state (35%). The therapeutical route was marked by medical treatment (42%), religious (41%), herbal treatment (9%). Altogether, 68.3% of patients had a social support, either given by friends (47.6%) or were financially supported (36.6 %) .
    Conclusion: This study was oriented towards formalization or integration of a psycho-oncological intervention during the management of a black patient group suffering from various cancers.

    Abstract Purpose: Several studies have associated the serum vitamin D level with total testosterone levels and the prostate volume. Herein, we investigated the effect of vitamin D supplementation on testosterone, prostate, and lower urinary tract symptoms (LUTS) in men.
    Materials and methods: Men over 40 years of age diagnosed with a vitamin D deficiency (25[OH]D <20 ng/mL) who received vitamin D supplementation for one year were included in the study and administered 25,000 IU of cholecalciferol every 2 weeks. Prostate ultrasound, uroflowmetry, postvoid residual urine volume measurement, and serological tests (serum testosterone levels,
    Results: A significant increase was observed in the vitamin D level following one year of vitamin D supplementation, with a significant decrease in the postvoid residual urine volume, total IPSS score and without a significant change in the prostate volume. Improved psychological subscale score of AMS questionnaire was observed with a statistical significance.
    Conclusions: Vitamin D supplementation suppressed the increase in the prostate volume and improved the LUTS. Although there is no direct effect on serum testosterone levels, vitamin D supplementation helped improve hypogonadal symptoms.

    Abstract Background: Vitamin D (vit-D) deficiency is highly prevalent in the Korean population, highlighting the need for accurate measurements. In this study, the interferences by endogenous and cross-reactive substances were compared between routine vit-D immunoassays and mass spectrometry (MS) methods.
    Methods: Two MS methods and 4 immunoassays from different manufacturers (Abbott, Beckman Coulter, Roche, Siemens) were compared. Residual samples that were icteric, lipemic, hemolyzed, high in rheumatoid factor, from myeloma patients, or patients undergoing hemodialysis were collected. Also, 4 levels of National Institute of Standards and Technology (NIST) Standard Reference Material 972a, and 12 samples serially spiked with 3-epi-25-OH-D
    Results: Significant interferences were observed in hemolytic (Roche), icteric (Beckman and Siemens) and lipemic samples (all 4 immunoassays). Level 4 NIST material and 3-epi-25-OH-D
    Conclusion: Most observed interferences were consistent with manufacturers' claims, but overall improvement of immunoassay bias limits is required. Awareness of potential interference is important to increase the accuracy of vit-D measurements. Moreover, care is due when interpreting vit-D results of newborns, infants and less commonly, pregnant women, who are known to have physiologically high levels of the highly cross-reactive 3-epi-25-OH-D

    Abstract Purpurin, an anthraquinone, has potent anti-oxidant and anti-inflammatory effects in various types of brain damage. In a previous study, we showed that purpurin exerts neuroprotective effects against oxidative and ischemic damage by reducing pro-inflammatory cytokines. In the present study, we investigated the effects of purpurin against D-galactose-induced aging phenotypes in mice. Exposure to 100 mM D-galactose significantly decreased cell viability in HT22 cells, and purpurin treatment significantly ameliorated the reduction of cell viability, formation of reactive oxygen species, and lipid peroxidation in a concentration-dependent manner. Treatment with 6 mg/kg purpurin significantly improved D-galactose-induced memory impairment in the Morris water maze test in C57BL/6 mice and alleviated the reduction of proliferating cells and neuroblasts in the subgranular zone of the dentate gyrus. In addition, purpurin treatment significantly mitigated D-galactose-induced changes of microglial morphology in the mouse hippocampus and the release of pro-inflammatory cytokines such as interleukin-1β, interleukin-6, and tumor necrosis factor-α. In addition, purpurin treatment significantly ameliorated D-galactose-induced phosphorylation of c-Jun N-terminal kinase and cleavage of caspase-3 in HT22 cells. These results suggest that purpurin can delay aging by reducing the inflammatory cascade and phosphorylation of the c-Jun N-terminal in the hippocampus.

    Abstract Background: High-intensity focused ultrasound (HIFU) serves as a noninvasive stereotactic system for the ablation of brain metastases; however, treatments are limited to simple geometries and energy delivery is limited by the high acoustic attenuation of the calvarium. Minimally-invasive magnetic resonance-guided robotically-assisted (MRgRA) needle-based therapeutic ultrasound (NBTU) using multislice volumetric 2-D magnetic resonance thermal imaging (MRTI) overcomes these limitations and has potential to produce less collateral tissue damage than current methods.
    Objective: To correlate multislice volumetric 2-D MRTI volumes with histologically confirmed regions of tissue damage in MRgRA NBTU.
    Methods: Seven swine underwent a total of 8 frontal MRgRA NBTU lesions. MRTI ablation volumes were compared to histologic tissue damage on brain sections stained with 2,3,5-triphenyltetrazolium chloride (TTC). Bland-Altman analyses and correlation trends were used to compare MRTI and TTC ablation volumes.
    Results: Data from the initial and third swine's ablations were excluded due to sub-optimal tissue staining. For the remaining ablations (
    Conclusion: We used a volumetric MRTI technique to accurately track thermal changes during MRgRA NBTU in preparation for human trials. Improved volumetric coverage with MRTI enhanced our delivery of therapy and has far-reaching implications for focused ultrasound in the broader clinical setting.

    Abstract: ... of lysosomes through restoration of cathepsin D in disease conditions. ...

    Abstract L-serine is a non-essential amino acid endogenously produced by astrocytes and is abundant in human diets. Beneficial roles of the metabolic products from L-serine in various conditions in the brain including neuronal development have been reported. Through several preclinical studies, L-serine treatment was also shown to offer beneficial therapeutic effects for brain damage such as ischemic stroke, amyotrophic lateral sclerosis, and Parkinson's disease. Despite evidence for the value of L-serine in the clinic, however, its beneficial effects on the propionic acid (PPA)-induced neuronal toxicity and underlying mechanisms of L-serine-mediated neuroprotection are unknown. In this study, we observed that PPA-induced acidic stress induces abnormal lipid accumulation and functional defects in lysosomes of hippocampal neurons. L-serine treatment was able to rescue the structure and function of lysosomes in PPA-treated hippocampal neuronal cells. We further identified that L-serine suppressed the formation of lipid droplets and abnormal lipid membrane accumulations inside the lysosomes in PPA-treated hippocampal neuronal cells. Taken together, these findings indicate that L-serine can be utilized as a neuroprotective agent for the functionality of lysosomes through restoration of cathepsin D in disease conditions.

    Title translation Preparation of healthcare workers against the threat of Ebola virus disease in Ivory Coast.
    Abstract Introduction: Since the declaration of the Ebola virus disease outbreak in West Africa, the government of Ivory Coast has organized the training of medical staff in all health regions of the country. This study was conducted one month after this training in order to assess the knowledge, attitudes and practices of health workers concerning Ebola virus disease in an Ivory Coast health region their preparation in relation to this disease.
    Methods: In May-June 2014, we conducted a descriptive cross-sectional study of 176 health workers from private and public health facilities in 5 health districts.
    Results: Among the respondents, 15.5% attended the training on Ebola disease organized by the Ministry of Health. They knew that the disease is transmitted from animals to humans by body fluids (85.6%), and from human to human by body fluids of a sick person or a cadavre (82.8%). 96% said they were at risk of contracting the disease.
    Discussion: In view of the persistent threat of the disease, ignorance of certain aspects of the disease could be a weakness in the prevention of nosocomial transmission of the disease. Knowledge of the disease should lead to adoption of prevention measures. However, routine use of protection equipment, including gloves, depends on its availability.
    Conclusion: The lack of infection prevention and control equipment could be a weak point in preparation of the response to an Ebola disease outbreak.
