Valvular heart diseases during pregnancy are complex with symptoms likely to affect patient’s life quality, and endanger both mother’s and child’s life. Our survey aims at studying the combination of valvular heart diseases with pregnancy at University Hospital Yalgado Ouedraogo. This study was a cross-sectional study conducted from January 1st, 2015 to March 31st, 2016 in the delivery room of gynecology and obstetrics department. Inclusion criteria were: the presence of acquired and known valvular heart diseases followed-up or not; suspected valvular heart disease confirmed by a Doppler echocardiography and patient’s consent to take part to the study. Twelve patients were involved in the study. The average age was 27.5 ± 3.9 years (extremes of 21 and 34 years). The average gestational age at the delivery time was 35 ± 4.7 weeks of amenorrhea with extremes reaching 25 and 39 weeks. None of the study patients were previously followed-up and treated for valvular heart diseases before pregnancy. Mitral disease was found among four patients. Seven cases had vaginal delivery. Two cases of spontaneous abortion were observed. We had seven hypotrophy newborns with an average weight of 2360 g at birth. Two patients suffering from congestive heart failure with a full type arrhythmia by atrial fibrillation were hospitalized in cardiology department. No death was reported during our study. Rheumatic valvular diseases are common among pregnant women. The cardiologist should plan pregnancies of patients suffering from valvular heart diseases. Treatment of those patients goes through the prevention of acute rheumatoid arthritis including a joint collaboration between cardiologists and gynecologists.

Background: Hypertension is a major public health concern in Burkina Faso. Its management relies on in-office medical setting blood pressure monitoring which is known to be an imperfect diagnosis tool. Objective: This study aims to assess the contribution of ambulatory blood pressure monitoring in the management of hypertension at Blaise Compaoré University Hospital. Methods: A monocentric descriptive retrospective study was conducted in the cardiology outpatient unit of Blaise Compaoré University Hospital. Patients aged at least 18 years who underwent ambulatory blood pressure monitoring between March 2013 and June 2015 were enrolled. Hypertension was defined as follows: average blood pressure over 24 hours > 130/80 mmHg, or diurnal blood pressure > 135/85 mmHg, or nocturnal blood pressure >120/70 mmHg. Data were analyzed using the SPSS 20.0 software. The threshold for significance was set at 5% for a validity interval at 95%. Chi square test was used for?the statistical analysis. Results: A total of 122 patients were enrolled. The main reasons for ambulatory monitoring were the evaluation of hypertensive therapy (51.6%) and the diagnosis confirmation (39.3%). The results of the ambulatory monitoring found 61.4% of the patients with hypertension and 37.7% with normal blood pressure. A treatment adjustment was made for 36.1% of the patients; an initiation of antihypertensive therapy was undertaken for 24.6%, an abstention from drug therapy was recommended?for 23.8%,?and the pursuit of previous treatment for 13.1% of the patients. Conclusion: Ambulatory blood pressure monitoring should be used more often in order to optimize the management of hypertension in our current practice.

Objective: Our study aimed at assessing the quality of life (QoL) of patients treated for chronic heart failure (HF), and analyzing the impact of certain factors on that QoL, in the cardiology department of Yalgado Ouédraogo University Hospital of Ouagadougou. Means and Method: It was a descriptive cross-sectional study, performed over a six-month period from May to October 2016. In the study, patients with age over 18 years were included, followed up for chronic HF for at least six months in the outpatient unit, from January 1st to December 31st 2015. The questionnaire “Minnesota Living with Heart Failure” was used to assess the QoL. Results: Two hundred and four patients were enrolled. Most of them were living in Ouagadougou (82.8%). Sex ratio was 0.98, and mean age was 56.06 16.37 years. The mean overall QoL score was 17.8 16.5. QoL was considered good in its three dimensions, in more than 70% of patients. Looking at the mean scores, the male patients, the patients living in rural and semi-urban areas, the patients with impaired left ventricular ejection fraction and those with severe or end-stage renal failure had significant QoL impairment. Multiple linear regression reported significant correlation between QoL impairment and the following factors (p value < 0.05 for all variables): marital life, number of hospitalizations for acute HF, and NYHA functional stage. Conclusion: Marital life, number of hospitalizations for acute decompensation, and NYHA functional stage were predictive factors of QoL impairment. MLHF questionnaire should be commonly used to assess the efficiency of HF management. Self administration instead of assistance in filling the questionnaire, could insure a more objective valuation of QoL.

Abstract: We performed bench-testing of a set of commercial ICP sensors. In our experimental setup, the ICP sensor was placed in a container with 0.9% NaCl solution. A test person was charged 0.5 - 10 kV, and then delivered ESD's to the sensor by touching a metal rod that was located in the container. The continuous pressure signals were recorded continuously before/after the ESD's, and the pressure readings were stored digitally using a computerized systemA total of 57 sensors were tested, including 25 Codman ICP sensors and 32 Raumedic sensors. When charging the test person in the range 0.5-10 kV, typically ESD's in the range 0.5 - 5 kV peak pulse were delivered to the ICP sensor. Alterations in baseline pressure ≥ 2 mmHg was seen in 24 of 25 (96%) Codman sensors and in 17 of 32 (53%) Raumedic sensors. Lasting changes in baseline pressure > 10 mmHg that in the clinical setting would affect patient management, were seen frequently for both sensor types. The changes in baseline pressure were either characterized by sudden shifts or gradual drifts in baseline pressure.The baseline pressures of commercial solid ICP sensors can be altered by ESD's at discharge magnitudes that are clinically relevant. Shifts in baseline pressure change the ICP levels visualised to the physician on the monitor screen, and thereby reveal wrong ICP values, which likely represent a severe risk to the patient.In patients with brain injury due to traumatic brain injury, stroke, or complications to neurosurgery, the continuous monitoring of intracranial pressure (ICP) is crucial for surveillance [1-3], even though no randomized trials have confirmed the benefit of ICP monitoring in patients with brain injury [4].Modern ICP monitoring was first introduced by Janny in 1950 [5] and Lundberg in 1960 [6]. While ICP initially was mostly measured from fluid-filled catheters in connection with the ventricular cerebrospinal fluid (CSF), the first ICP micro transducers were introduced in the 1980's [7,8].

Abstract: A comparative observational study in Swiss primary care with written survey completed by patients who visited a GP one month earlier. 6133 patients older than 16 years of 170 certified CAM physicians, of 77 non-certified CAM physicians and of 71 conventional physicians were included. Patients completed a questionnaire aimed at symptom relief, patient satisfaction, fulfilment of expectations, and quality of patient-physician interaction (EUROPEP questionnaire).CAM physicians treated significantly more patients with chronic conditions than COM physicians. CAM Patients had significant higher healing expectations than COM patients. General patient satisfaction was significantly higher in CAM patients, although patient-reported symptom relief was significantly poorer. The quality of patient-physician communication was rated significantly better in CAM patients.The study shows better patient-reported outcomes of CAM in comparison to COM in Swiss primary care, which is related to higher patient satisfaction due to better patient-physician communication of CAM physicians. More effective communication patterns of these physicians may play an important role in allowing patients to maintain more positive outcome expectations. The findings should promote formative efforts in conventional primary care to improve communication skills in order to reach the same levels of favourable patient outcomes.The trend that patients seek more and more help in complementary and alternative medicine (CAM) is a phenomenon in almost all western healthcare systems. CAM therapies that are used instead of conventional medicine are termed "alternative." CAM therapies used alongside conventional medicine are said to be "complementary." With reference to this merging of CAM with conventional biomedicine (COM) an increasing number of clinicians and researchers uses the term "integrative" medicine. However, it is argued that combination medicine (CAM added to COM) is not integrative as such. Integrative

Abstract: The data were derived from the complete claims data of Swiss health insurers for 2004 and included 21.4 million consultations provided by 6564 Swiss primary care physicians on a fee-for-service basis. Socio-demographic data were obtained from the Swiss Federal Statistical Office. Utilisation-based health service areas were created and were used as observational units for statistical procedures. Multivariate and hierarchical models were applied to analyze the data.Models within the study allowed the definition of 1018 primary care service areas with a median population of 3754 and an average per capita consultation rate of 2.95 per year. Statistical models yielded significant effects for various geographical, socio-demographic and cultural factors. The regional density of physicians in independent practice was also significantly associated with annual consultation rates and indicated an associated increase 0.10 for each additional primary care physician in a population of 10,000 inhabitants. Considerable differences across Swiss language regions were observed with reference to the supply of ambulatory health resources provided either by primary care physicians, specialists, or hospital-based ambulatory care.The study documents a large small-area variation in utilisation and provision of health care resources in Switzerland. Effects of physician density appeared to be strongly related to Swiss language regions and may be rooted in the different cultural backgrounds of the served populations.Previous research on variations in the volume of physician services in geographic areas has emphasized that an additional use of services is not necessarily associated with improved health in the corresponding populations[1]. After controlling for input prices and health status, it was found that the volume of physician services is driven partly by local practice patterns and partly by differences in physician density and speciality. However, an association between greater volume a

Abstract: Background: Centre MURAZ of Bobo-Dioulasso (Burkina Faso) organized in 2009 and 2010 a system of Cerobro-Spinal Fluid (CSF) collection in eight pilot Districts as an initial step for the future Ministry of Health’s led strategy of individual surveillance in a context of meningococcal conjugate A vaccine introduction. Methods: CSF samples were analyzed with Polymerase Chain Reaction (PCR). This allowed for meningitis etiologies dynamics studies in the pilot Districts. Results: Because of geographical difficulties and lack of means, less than 40% of suspected cases had their CSF analyzed at PCR reference laboratory. In 2009, among confirmed cases at reference laboratory, Sp (Streptococcus pneumonia), NmA (Neisseria meningitis A) and Hib (Hemophilus influenzae b) were responsible respectively for 90%, 6.6% and 4.4% of cases. In 2010, serogroup distribution among confirmed cases was: Sp 62.7%, NmX 32.2% and NmA 5.1%. Sp which was continuously present in Burkina Faso takes more significant proportions, just as serogroup X which until there was sporadically encountered. The attack rates of NmX were tree to twelve times higher than for NmA in the two Districts where NmX has been notified. Conclusion: As a consequence of such results, efforts must be maintained in epidemiologic surveillance field and in reinforcement of laboratory capacities. Fast care should be guaranteed to patients with adequate antibiotics according to country national guideline and chemoprophylaxis measures should be undertaken among contacts of patients to prevent secondary cases. A plea must be made on one hand for pneumococcal vaccine introduction in Burkina Faso and on other hand towards manufacturers for taking into account serogroup X into meningococcal polyvalent vaccine composition. With this polyvalent vaccine including serougruop X, we suggested to conduct periodically mass campaign vaccination of people before the beginning of meningitis epidemiological season.

Abstract: Certain areas in Senegal have a serious problem of high fluoride and salinity in underground water because of soil properties. This water currently used for drink has a bad taste on consumption and caused diseases like dental fluorosis and skeletal fluorosis. A membrane filtration plant constructed by Pall Corporation was improved through nanofiltration (NF) and Low Pressure Reverse Osmosis (LPRO). Both NF and LPRO membranes were shown applicable for salinity and fluoride ions removal from brackish and high fluorinated drinking water in a remote community. The NF membrane has given a fluorine retention rate varying between 63.3% and 71% while the LPRO membrane allow to reach 97 to 98.9% for fluorine rejection. Highest salinity rejection rates expressed through conductivity measurements are around 46% and 97% for respectively NF and LPRO.
T Cell Mediated Antibody lnvariance in an Immune Response Against A Bacterial Carbohydrate Antigen Requires CD28/B7–1 Costimulation

Clinical and Developmental Immunology , 2001, DOI: 10.1155/2001/87168
Abstract: The humoral immune response against α(1→3) dextran (Dex) in BALB/c mice is characterized by the formation of predominantly IgM antibodies bearing the J558 idiotype. IgG antibodies do not appear in euthymic mice. In athymic animals however, the response proceeds to a vigorous IgG production. In euthymic mice formation of IgG is suppressed by J558 idiotype- specific regulatory T cells recognizing in association with I-Ed and in cognate T/B interaction the VH CDR3 derived peptide of the J558 idiotpye. Only B-2 lymphocytes produce IgG whereas B-1 cells do not participate in the production of this Ig class. Using a novel synthetic all α(1→3)-D-gluco configurated tetrasaccharide the Dex-specific B cells can for the first time be analyzed in FACS. In experiments using this newly designed low molecular Dex no signs of B cell apoptosis can be found. This demonstrates a true silencing of persisting Bγ memory cells and supports previous by adoptive transfer experiments. In this suppression an involvement of CD28/B7–1 interaction can be demonstrated which is a necessary costimulatory suppression signal in addition to the cognate TCR/peptide-I-Ed interaction between J558 Id-specific T cells and J558 idiotype beating B cells. This results in an activation of 178–4 Ts cells, leading to an overall suppression of the Dex-specific IgG isotype production on the one hand and on the other hand provides a signal for the survival and clonal expansion of J558 Id-positive B cells.
