Utility of presepsin (sCD14-ST) as a diagnostic and prognostic marker of sepsis in the emergency department
2015
Presepsin (PSEP) is released during infectious diseases and can be detected in the blood. PSEP has shown promising results as sepsis marker. We examined the diagnostic and prognostic validity of PSEP in patients suspicious of sepsis on admission in the emergency department (ED). Methods One hundred twenty three patients with signs of SIRS and/or sepsis and 123 healthy individuals were enrolled. PSEP was determined on admission, after 8, 24 and 72 h. Results Mean PSEP concentrations of the control group and the patient group were 130 and 1945 pg/ml. PSEP differed between SIRS, sepsis, severe sepsis and septic shock and showed strong association with 30-day mortality ranging from 10.3% in the…
Helicobacter pylori infection in Burkina Faso: an enigma within an enigma.
2004
Background. In Burkina Faso, in contrast with high rates of Helicobacter pylori infection from an early age, the prevalence of H. pylori-associated diseases (ulcer and gastric cancer) is low. Aims. To look for the prevalence of H. pylori in healthy natives of Burkina Faso, both children and adults. Methods. We studied the prevalence of H. pylori infection in 258 healthy natives of Burkina Faso (70 children aged 6 months–15 years and 188 adults aged 16–65 years), using a serological screening (IgA and IgG H. pylori antibodies). All the studied subjects underwent a questionnaire regarding their life-style, socio-economic status, dietary habits and hygienic sanitary conditions. Data concerning…
Discovery of an epidermoid of the skull concomitant with a homolateral subacute traumatic subdural hematoma
1979
The case of a man of 32 years with an epidermoid of the left side of the skull is reported. The tumor itself was asymptomatic and was discovered accidentally because of a subdural hematoma on the same side. After a closed head injury, this patient had symptoms of an intracranial space occupying lesion (hematoma) on the left after a symptom-free interval. The left carotid angiogram demonstrated the characteristic picture of a subdural hematoma in the left parieto-temporo-occipital region. At the same time, characteristic changes in the skull on the same side, which were more apparent after removal of the hematoma, suggested an epidermal tumour of the skull. This was verified at operation.
Strength and Latency of the HP-SAP Closed Loop Variability Interactions in Subjects Prone to Develop Postural Syncope
2019
The coupling and latency between heart period (HP) and systolic arterial pressure (SAP) variability can be investigated along the two arms of the HP-SAP closed loop, namely along the baroreflex feedback from SAP to HP, and along the feedforward pathway from HP to SAP. This study investigates the HP-SAP closed loop variability interactions through cross-correlation function (CCF). Coupling strength and delay between HP and SAP variability series were monitored in 13 subjects prone to develop orthostatic syncope (SYNC, 28±9 yrs, 5 males) and in 13 subjects with no history of postural syncope (noSYNC, age: 27±8 yrs, 5 males). Analysis was carried out at rest in supine position (REST) and durin…
Exploring directionality in spontaneous heart period and systolic pressure variability interactions in humans: implications in the evaluation of baro…
2004
Although in physiological conditions RR interval and systolic arterial pressure (SAP) are likely to interact in a closed loop, the traditional cross-spectral analysis cannot distinguish feedback (FB) from feedforward (FF) influences. In this study, a causal approach was applied for calculating the coherence from SAP to RR ( Ks-r) and from RR to SAP ( Kr-s) and the gain and phase of the baroreflex transfer function. The method was applied, compared with the noncausal one, to RR and SAP series taken from 15 healthy young subjects in the supine position and after passive head-up tilt. For the low frequency (0.04–0.15 Hz) spectral component, the enhanced FF coupling ( Kr-s = 0.59 ± 0.21, signi…
Selected Predictors of the Sense of Intimacy in Relationships of Young Adults
2019
The main research objective of this study was seeking the predictive role of closeness to parents, attachment, identity style, identity commitment, type of relationship, and having children in intimacy among young women and men. Many studies indicate differences in the level of engagement, communication, and satisfaction in relationships. The study group comprised 227 people, including 114 women (M = 29.99
Heated breathing tubes affect humidity output of circle absorber systems.
1993
Abstract Study Objective: To verify whether the airway climate in circle systems can be improved with heated breathing tubes. Design: Randomized, controlled, prospective clinical study. Setting: Operating theater of the Department of Maxillofacial Surgery. Patients: 26 adult patients undergoing prolonged anesthesia. Interventions: A total of 26 prolonged anesthetics were conducted in adult patients using a minimal fresh gas flow rate (0.6 L/min) and silicon breathing tubes (16 mm internal diameter) containing a heated coil. Group 1 ( n = 10 patients) was the control group; breathing tubes were unheated. In Group 2 ( n = 10 patients), breathing tubes were heated to 30°C. In Group 3 ( n = 6 p…

Internal Fixation in Postpartum Symphysis Pubis Rupture: Report of Three Cases
1997
We present three patients with postpartum symphysis pubis rupture whose severe complaints persisted after conservative treatment. All three ruptures were stabilized with open reduction and internal fixation. There were no postoperative problems, and implants were removed after a mean period of six months. Patients were free of complaints after implant removal. In select cases, operative treatment of postpartum symphysiolysis may be indicated.
Structural Mechanism of N-Methyl-D-Aspartate Receptor Type 1 Partial Agonism
2012
N-methyl-D-aspartate (NMDA) receptors belong to a family of ionotropic glutamate receptors that contribute to the signal transmission in the central nervous system. NMDA receptors are heterotetramers that usually consist of two GluN1 and GluN2 monomers. The extracellular ligand-binding domain (LBD) of a monomer is comprised of discontinuous segments that form the functional domains D1 and D2. While the binding of a full agonist glycine to LBD of GluN1 is linked to cleft closure and subsequent ion-channel opening, partial agonists are known to activate the receptor only sub-maximally. Although the crystal structures of the LBD of related GluA2 receptor explain the mechanism for the partial a…
