Chromophoric dissolved organic matter (CDOM) represents the optically active fraction of the bulk dissolved organic matter (DOM) pool. Recent evidence pointed towards a microbial source of CDOM in the aquatic environment and led to the proposal that phytoplankton is not a direct source of CDOM, but that heterotrophic bacteria, through reprocessing of DOM of algal origin, are an important source of CDOM. In a recent experiment designed at looking at the effects of elevated pCO(2) on blooms of the coccolithophorid alga Emiliania huxleyi, we found that despite the 3 different pCO(2) levels tested (190, 414 and 714 ppm), no differences were observed in accumulation of CDOM over the 20 d of incubation. Unlike previous mesocosm experiments where. relationships between CDOM accumulation and bacterial abundance have been observed, none was observed here. These results provide some new insights into the apparent lack of effect of pCO(2) on CDOM accumulation in surface waters, and question the previously proposed mechanisms and rates of CDOM production in natural phytoplankton blooms.

Hypothesis / aims of study The aim of this study was to prospectively evaluate the efficacy of the TVT-O inside-out procedure for the treatment of female stress urinary incontinence (SUI). Study design, materials and methods From March 2003 through September 2003, 53 patients with clinical evidence of SUI participated in this prospective clinical trial. Preoperative evaluation included complete history, physical examination, multichannel urodynamics, urine analysis, and cystoscopy. None of the patients presented the following exclusion criteria: post-void residual volume (PVR) ≥ 100 cc, detrusor overactivity or acontractility, contraindication to anesthesia, pregnancy, neurological pathology, or active urinary or vaginal infection. All patients met the following inclusion criteria: age > 25 and < 85 years, clinically demonstrated SUI, positive Ulmsten test, and maximum cystometric capacity ≥ 300 mL. In all patients, a sub-urethral tape (Gynecare®) was inserted by one single surgeon via an inside-out transobturator approach (TVT-O), as previously described (1). Evaluation of SUI, urgency/urge incontinence, daytime urinary frequency/nocturia, and lower urinary tract symptoms (LUTS) suggestive of bladder outlet obstruction/retention was carried out using the Measurement of Urinary Handicap scale questionnaire (2). The importance of urinary incontinence was assessed with a visual analog scale graded from 0 to 10. Quality of life (QoL) assessment was performed using the validated Ditrovie self-administered questionnaire. Outpatient follow-up was perfomed at 1 and 6 months, and every 6 months thereafter. Follow-up evaluation included physical examination with a stress test, uroflowmetry, PVR, and symptom, visual analog, and QoL scales scoring. Cure was defined as no leakage based on both symptom scale scoring and physical examination. Improvement was defined as at least a 50% decrease in symptoms based on the questionnaire’s evaluation. Chart review was conducted by a physician not associated with the surgical procedure. The specific protocol used in this study was approved by the Medical Ethics committee of our Institution. All patients had given their written informed consent. Methods, defintions,and units conform to the standards recommended by the ICS. Results Mean age of the patients was 61.2 years (36 to 80). Of the 53 patients, 20 had undergone previous pelvic surgery. Forty-eight patients suffered from SUI. Five patients did not complain of SUI but had clinical evidence of SUI after reduction of pelvic organ prolapse (POP) during vaginal examination. The TVT-O procedure was associated with POP cure (performed before TVT-O) in 12 patients. Maximal urethral closure pressure was < 30 cm H20 in 6 patients. Follow-up time was ≥ 6 months in all women (max = 12.5; mean = 8). A total of 33 and 20 women received spinal and general anesthesia, respectively. Intraoperative blood loss was < 100 cc in all cases. No vaginal wall, urethral, or bladder perforation was encountered. No hematoma, neurological complication, fistula, vaginal or urethral erosion, or tape rejection was observed. Some patients reported pain symptoms, directly after the procedure, mainly located in the thigh regions (either uni- or bilaterally). Pain was always mild, never requiring opioid antalgics. No patient complained of persistent pain; indeed, pain had completely vanished within the first post-operative month in all cases. At the latest follow-up visit, PVR was < 100 cc and max flow rate was ≥ 10 mL/sec in 49 (92.4%) and 39 (73.6%) patients, respectively. One patient underwent an immediate tape release procedure for complete retention 2 days after TVT-O. Thereafter, the patient had no PVR and was completely dry. The tape was sectioned in 2 patients for chronic retention and/or urgency associated with bladder outlet obstruction, 4 and 7 months after the operation. Based on the SUI questionnaire evaluation and physical examination, 50 (94.3%) patients were cured. SUI symptoms had improved in 1 patient and had not changed in another. One patient with POP not complaining of SUI preoperatively (but with clinically demonstrated SUI following POP reduction) developed SUI after POP cure associated with TVT-O. Analysis of the urgency questionnaire’s results revealed that among the 53 patients, 32 did not complain of any urgency before the operation. Of these 32 patients, 3 patients developed de novo urgency, with one of them requiring tape sectioning because of obstruction-associated urge incontinence. Among the 21 patients with preoperative urge symptoms, 15 of them reported disappearance of urgency after the procedure. Urge symptoms were unchanged in the remaining 6 patients. Daytime frequency/nocturia symptoms scale scoring showed that 4 patients had a worsening of these symptoms while all other patients were either improved or unchanged. LUTS suggestive of bladder outlet obstruction/retention appeared or worsened in 3 patients, amongst which the 2 patients who required tape sectioning. These symptoms were unchanged or decreased (mainly in patients with associated POP cure) in all other patients. Analysis of the urinary incontinence visual analog and QoL scale scores demonstrated that the majority of patients reported disappearance of urinary leakage together with significant improvement of their QoL (Figures 1 and 2). Interpretation of results As already suggested by the results of a recent feasibility study (1), TVT-O appears to be associated with a minimal risk of peri-operative complications. Indeed, in our present prospective study, no injury to the bladder, vagina, or urethra was encountered and we have not observed any vascular, digestive or neurological complication. Our data suggest that TVT-O is associated with high objective and subjective SUI cure rates and a low incidence of post-operative complications. Longer follow-up times are required to determine the long-term efficacy of TVT-O. Concluding message The short term results of this prospective study suggest that TVT-O is a safe and efficient surgical procedure for the treatment of female SUI. References 1.

Stable carbon and nitrogen isotopes (delta(13)C and delta(15)N) and trace metals (Cd, Zn, Cu, Fe, Se, and Hg) were analysed in the tissues of 46 harbour porpoises (Phocoena phocoena relicta) caught in fishing nets along the Ukrainian coasts between 1997 and 1998. Mean delta(13)C values differed significantly between male and female harbour porpoises suggesting a trophic segregation between sexes with a more coastal distribution for females at least during their gestation and nursing periods. Hepatic Hg was correlated to delta(13)C measurements, reflecting a different exposure linked to coastal vs offshore feeding habitats. A geographical comparison with existing data from other regions showed general low levels of Hg, Cd, Cu and Zn in the tissues of harbour porpoises from the Black Sea compared to other Atlantic and North Sea areas.

It is now 30 years since the first motor unit number estimation (MUNE) technique was introduced by Allan McComas as a way of providing an objective, sensitive and reproducible means of measuring the number of motor axons in living human muscle or muscle group. MUNE techniques have substantially evolved over the past decade and have been applied, with increasing frequency, to the study of age effects on motoneurone population and muscle denervating disorders such as amyotrophic lateral sclerosis (ALS), spinal muscular atrophy, poliomyelitis and different types of inherited and acquired peripheral neuropathies. In the future, one of the most important topics involving MUNE, will probably be its use in monitoring the progress of ALS patients undergoing experimental drug trials. However, among incremental, multiple point stimulation, spike-triggered averaging, F-wave analysis and statistical methods, there is no consensus about the best MUNE method. There is only a general feeling that some techniques are more valid than others. For this reason, in the present review, brief descriptions of the distinct MUNE methods are presented. In the second part of the paper, advantages and limitations (alternation, sampling errors, temporal registration etc...) of the most commonly employed procedures are considered. [less ▲]
