The present study aimed to assess the prevalence of symptoms of anxiety and depression among health professionals in the three most affected regions in Cameroon.. The study was a descriptive cross-sectional type. Participants were health care professionals working in the three chosen regions of Cameroon. The non_probability convinient sample technique and that of the snowball were valued via a web questionnaire. The non-exhaustive sample size was 292. The diagnosis of anxiety and depression was made by the HAD (Hospital Anxiety and Depression scale).. Les auteurs rapportent que le secteur médical est classé à un plus grand risque de contracter le COVID-19 et de le propager potentiellement à d’autres. Le nombre sans cesse croissant de cas confirmés et suspects, la pression dans les soins, l’épuisement des équipements de protection individuelle et le manque de médicaments spécifiques peuvent contribuer à un vécu anxio-dépressif significatif. La présente étude s’est donnée pour ambition d’évaluer la prévalence des symptômes de l’anxiété et de la dépression chez les professionnels de santé dans les trois Régions les plus concernées au Cameroun..

A group of 21 complete spinal cord injury patients, beyond the phase of spinal shock, were given a treatment of cisapride at random, 10 mg four times a day for 4 weeks. Cystometry was performed first before the start and during the following 4 weeks. No statistically significant difference could be found in the urodynamic parameters between the two groups at the first cystometry. No statistically significant change of the urodynamic parameters could be demonstrated with the treatment, although a non-statistically significant bladder stimulating effect was present in a majority of the patients in the cisapride group.

To analyze the use of alvimopan, a peripheral mu-opioid receptor antagonist, in expediting gastrointestinal recovery after benign abdominal urinary tract reconstruction. Alvimopan use has been well defined in the management of radical cystectomy and urinary diversion for oncologic indications. It has not been studied in benign abdominal genitourinary reconstruction.. Patients who underwent urinary reconstruction utilizing harvested bowel segments for benign conditions from 12/2014-7/2019 were retrospectively reviewed. From 5/2018-7/2019 our institution approved the use of perioperative alvimopan in the aforementioned patients (N = 11), who were paired 1:2 with patients from a cohort of alvimopan-eligible patients who did not receive the drug (N = 22). Patients were paired by (1) type of reconstruction and (2) presence of neurogenic bowel-bladder (NBB).. Of the 70 patients who underwent urinary reconstruction during the study period, 46 patients (66%) were eligible to receive alvimopan. Length of stay was shorter for the alvimopan group compared to the non-alvimopan group (median 5 days [IQR 4-5 days] vs. 8 days [IQR 6-11 days]; P = 0.002). Time to first bowel movement was shorter for the alvimopan group (median 4 days [IQR 3-4 days] vs. 6 days [IQR 4-7], P = 0.001). No patient treated with alvimopan required a nasogastric (NG) tube for post-operative ileus compared to 7 (32%) patients in the non-treatment group (P = 0.035). Post-operative complications and 30-day readmissions were similar between the two groups.. The use of perioperative alvimopan in benign abdominal urinary tract reconstruction expedited return of bowel function and decreased length of stay compared to a matched cohort of untreated patients.

Spinal cord injury (SCI) above the lumbosacral level results in lower urinary tract dysfunction, including (1) detrusor hyperreflexia, wherein bladder compliance is low, and (2) a lack of external urethral sphincter (EUS) control, leading to detrusor-sphincter dyssynergia (DSD) with poor voiding efficiency. Experimental studies in animals have shown a dense innervation of serotonergic (5-HT) fibers and multiple 5-HT receptors in the spinal reflex circuits that control voiding function. Here, we investigated the efficacy of NLX-112 (a.k.a. befiradol or F13640), in regulating lower urinary tract function after T8 contusive SCI in rats. NLX-112 is a very potent, highly-selective, and fully efficacious 5-HT

This study examines whether M(2) receptors contribute to direct contraction of the detrusor in human neurogenic and idiopathic overactive bladders.. Control detrusor muscle was obtained from patients undergoing cystectomy for bladder cancer, whilst overactive detrusor muscle was obtained from patients undergoing clam cystoplasty for idiopathic or neurogenic detrusor overactivity. The affinities of a range of subtype selective antagonists (DAMP, darifenacin, methoctramine R0-320-6206, and pirenzepine) were obtained in tissue bath experiments by using carbachol as the agonist. These affinity values were then compared with the known affinities for these antagonists at the muscarinic receptor subtypes.. An increased sensitivity to carbachol was observed in both the neurogenic and idiopathic overactive detrusors compared with the control human detrusor. The M(2)-selective antagonists (methoctramine, R0-320-6206) and M(1)-selective antagonist (pirenzepine) had low affinities, whilst the M(3)-selective antagonists (4-DAMP and darifenacin) had high affinities for the human detrusor muscarinic receptor in all three groups of tissues. The affinities (pK(B) values) for the five antagonists were consistent with antagonisms at the M(3) receptor in all three groups; Schild plot analysis indicated an action at this single receptor subtype.. Contraction mediated by muscarinic receptors is enhanced in idiopathic and neurogenic overactive detrusors compared with control detrusor. The direct contractile response to carbachol is mediated by the M(3) receptor in both human normal and overactive bladders, indicating no change in receptor subtype contribution to contraction in the disease state.

1 The M3 muscarinic receptor subtype is widely accepted as the receptor on smooth muscle cells that mediates cholinergic contraction of the normal urinary bladder and other smooth muscle tissues, however, we have found that the M2 receptor participates in contraction under certain abnormal conditions. The aim of this study was to determine the effects of various experimental pathologies on the muscarinic receptor subtype mediating urinary bladder contraction. 2 Experimental pathologies resulting in bladder hypertrophy (denervation and outlet obstruction) result in an up-regulation of bladder M2 receptors and a change in the receptor subtype mediating contraction from M3 towards M2. Preventing the denervation-induced bladder hypertrophy by urinary diversion prevents this shift in contractile phenotype indicating that hypertrophy is responsible as opposed to denervation per se. 3 The hypertrophy-induced increase in M2 receptor density and contractile response is accompanied by an increase in the tissue concentrations of mRNA coding for the M2 receptor subtype, however, M3 receptor protein density does not correlate with changes in M3 receptor tissue mRNA concentrations across different experimental pathologies. 4 This shift in contractile phenotype from M3 towards M2 subtype is also observed in aged male Sprague-Dawley rats but not females or either sex of the Fisher344 strain of rats. 5 Four repeated, sequential agonist concentration response curves also cause this shift in contractile phenotype in normal rat bladder strips in vitro, as evidenced by a decrease in the affinity of the M3 selective antagonist p-fluoro-hexahydro-sila-diphenidol (p-F-HHSiD). 6 A similar decrease in the contractile affinity of M3 selective antagonists (darifenacin and p-F-HHSiD) is also observed in bladder specimens from patients with neurogenic bladder as well as certain organ transplant donors. 7 It is concluded that although the M3 receptor subtype predominantly mediates contraction under normal circumstances, the M2 receptor subtype can take over a contractile role when the M3 subtype becomes inactivated by, for example, repeated agonist exposures or bladder hypertrophy. This finding has substantial implications for the clinical treatment of abnormal bladder contractions.

Increased afferent nerve activity may have an important role in the pathogenesis of neurogenic detrusor overactivity. We tested the efficacy of the neuokinin-2 receptor antagonist M274773 ((S)-N-[2-(3,4-Dichlorophenyl)-4-[4-(2-oxoperhydro-pyrimidin-l-yl) piperidino]butyl]-N-methylbenzamide dihydrochloride) on neurogenic detrusor overactivity after spinal cord injury in rats.. Included in this study were 48 adult Sprague-Dawley rats (Charles River, Montreal, Quebec, Canada). Six animals served as normal controls, while 32 underwent spinal cord transection at the 10th thoracic vertebra. Two weeks after spinal cord injury 6 animals underwent filling cystometrography to confirm neurogenic detrusor overactivity, while another 12 served as paraplegic controls. The remaining 24 paraplegic animals were used to test the drug and they were divided into 2 equal groups of 12. Group 1 received the drug at a dose of 0.3 mg/kg daily, while group 2 received a dose of 0.6 mg/kg daily. Each paraplegic control and treatment group was further subdivided into 2 subgroups of 6 rats each. In subgroup 1 filling cystometrography was done 3 weeks after spinal cord injury, while in subgroup 2 it was done 4 weeks after spinal cord injury.. Three weeks after spinal cord injury neurogenic detrusor overactivity developed in all paraplegic control animals with a mean bladder capacity +/- SD of 0.7 +/- 0.2 ml and a mean voiding pressure of 59 +/- 14.2 cm H2O. Neurogenic detrusor overactivity resolved in 50% and 83% of the animals that received M274773 for 1 week at doses of 0.3 and 0.6 mg/kg daily, respectively. Mean cystometric bladder capacity was 1.2 +/- 0.5 vs 1.3 +/- 0.4 ml and mean voiding pressure was 46.1 +/- 10.8 vs 40 +/- 9.9 cm H2O in animals that received 0.3 vs 0.6 mg/kg daily, respectively. The drug produced better urodynamic results when given for 2 weeks rather than 1 week.. M274773 is effective for neurogenic detrusor overactivity after spinal cord injury in the rat. It may provide an alternative clinical treatment option for neurogenic detrusor overactivity and urgency/frequency syndrome. This new neurokinin-2 selective antagonist has time and dose response effects, which further suggests the potential for clinical application.

To compare the serotonin (5-HT)4-receptor-mediated effects of 5-HT on the potentiation of cholinergic responses to electrical-field stimulation (EFS) in isolated strips of detrusor muscle from patients with normal or neurogenic overactive bladders.. Strips of detrusor muscle were field-stimulated (10 Hz, 0.01 ms duration, 60 V for 5 s) at 100-s intervals until consistent responses were obtained. In the presence of methiothepin, ketanserin and ondansetron (all 1 mumol/L) to block 5-HT1, 5-HT2 and 5-HT3 receptors, respectively, the cumulative administration of 5-HT or the selective 5-HT4 agonist cisapride, produced concentration-dependent enhancement of responses to EFS in both types of tissue.. The maximum potentiation induced by 5-HT in neurogenic overactive detrusor muscle was reduced (P < 0.05) by about half compared to normal detrusor muscle, but EC50 values obtained in normal and overactive tissue were not significantly different. Cisapride was less potent than 5-HT and acted as a partial agonist relative to 5-HT. The selective 5-HT4 receptor antagonist RS-100235 was a potent antagonist of the 5-HT-induced potentiation of responses to EFS. At 3 nmol/L RS-100235 antagonized the effects of 5-HT in both groups of tissues without affecting the maximum responses. The affinity estimates (apparent pKB values of 9.2-9.5) for this antagonist were similar in normal and overactive detrusor muscle.. These results indicate that 5-HT4 receptor-mediated potentiation of field-stimulated responses is lower in the neurogenic overactive detrusor muscle than in normal tissue. 5-HT4 receptor antagonist affinity is unchanged in the neurogenic overactive bladder.

Muscarinic facilitation of 14C-ACh release from post-ganglionic parasympathetic nerve terminals was studied in bladder strips prepared from spinal intact (SI) and spinal cord transected (SCT) rats. The spinal cord was transected at the lower thoracic spinal segments 3 weeks prior to the experiments. Using non-facilitatory stimulation (2 Hz) the release of ACh in spinal intact rats did not change in the presence of a non-specific muscarinic antagonist, atropine (100 nM), an M(1) specific antagonist (pirenzepine, 50 nM) or an M(1)-M(3) specific antagonist (4-DAMP, 5 nM). However, during a facilitatory stimulation paradigm (10 Hz or 40 Hz, 100 shocks) atropine and pirenzepine, but not 4-DAMP inhibited the release of ACh in bladders from spinal intact rats, indicating an M(1) receptor-mediated facilitation. In spinal cord transected rats, 2 Hz stimulation-induced release was significantly inhibited by atropine or 4-DAMP but not by pirenzepine indicating that a pre-junctional facilitatory mechanism mediated via M(3) muscarinic receptors could be induced by a non-facilitatory stimulation paradigm after spinal injury. In bladders of spinal cord transected rats, 10 Hz stimulation-evoked release of ACh was also inhibited by atropine and 4-DAMP (5 nM) but not by pirenzepine (50 nM). These results indicate that pre-junctional muscarinic receptors at cholinergic nerve endings in the bladder change after chronic spinal cord injury. It appears that low affinity M(1) muscarinic receptors are replaced by high affinity M(3) receptors. This change in modulation of ACh release may partly explain the bladder hyperactivity after chronic spinal cord injury.

We explored whether substance P (SP) via neurokinin (NK) receptor facilitates bladder afferent signaling and reactive oxygen species (ROS) formation in bladder in association with neurogenic inflammation. We evaluated ROS activity and cystometrograms as well as pelvic nervous activity in anesthetized rat bladder with SP stimulation. Our results showed that endogenous SP via NK(1), not NK(2), receptor mediated a micturition reflex. An increase in SP by electrical stimulation of the pelvic nerve or an increase in exogenous SP by intra-arterial or intrathecal administration can facilitate myogenic and neurogenic bladder contractions. Furthermore, exaggerated SP release increased ROS in the bladder and whole blood via increased mast cell degranulation, intercellular adhesion molecule expression, and leukocyte adhesion, a primary source of ROS in the inflamed bladder. Treatment with NK(1)-receptor antagonists or ROS scavengers reduced bladder intercellular adhesion molecule expression and ROS and ameliorated the hyperactive bladder response. Our study indicates that the mechanism by which SP participates in the neurogenic bladder may be complicated by its proinflammatory activity and its ability to stimulate ROS generation.

In vitro bladder contractions in response to cumulative carbachol doses were measured in the presence of selective muscarinic antagonists from rats which had their major pelvic ganglion bilaterally removed (denervation, DEN) or from rats in which the spinal cord was injured (SCI) via compression. DEN induced both hypertrophy (505+/-51 mg bladder weight) and a supersensitivity of the bladders to carbachol (EC50=0.7+/-0.1 uM). Some of the SCI rats regained the ability to void spontaneously (SPV). The bladders of these animals weighed 184+/-17 mg, significantly less than the bladders of non voiding rats (NV, 644+/-92 mg). The potency of carbachol was greater in bladder strips from NV SCI animals (EC50=0.54+/-0.1 uM) than either bladder strips from SPV SCI (EC50=0.93+/-0.3 microM), DEN or control (EC50=1.2+/-0.1 microM) animals. Antagonist affinities in control bladders for antagonism of carbachol induced contractions were consistent with M3 mediated contractions. Antagonist affinities in DEN bladders for 4-diphenlacetoxy-N-methylpiperidine methiodide (4-DAMP, 8.5) and para fluoro hexahydrosilodifenidol (p-F-HHSiD, 6.6); were consistent with M2 mediated contractions, although the methoctramine affinity (6.5) was consistent with M3 mediated contractions. p-F-HHSiD inhibited carbachol induced contraction with an affinity consistent with M2 receptors in bladders from NV SCI (pKb=6.4) animals and M3 receptors in bladders from SPV SCI animals (pKb=7.9). Subtype selective immunoprecipitation of muscarinic receptors revealed an increase in total and an increase in M2 receptor density with no change in M3 receptor density in bladders from DEN and NV SCI animals compared to normal or sham operated controls. M3 receptor density was lower in bladders from SPV SCI animals while the M2 receptor density was not different from control. This increase in M2 receptor density is consistent with the change in affinity of the antagonists for inhibition of carbachol induced contractions and may indicate that M2 receptors or a combination of M2 and M3 receptors directly mediate smooth muscle contraction in bladders from DEN and NV SCI rats.

We describe the case of a paraplegic patient who suffered traumatic spinal cord injury at the level of the twelfth thoracic vertebra. Within a short period of time following the injury, urinary (neuropathic bladder) and gastrointestinal (atomic colon) sequelae arose. Treatment with Cisapride (R 51 619, Janssen Pharmaceutica) was undertaken in an attempt to increase colonic motility and to reduce urinary retention. These goals were reached rapidly with a dose of 10 mg q.i.d.; the effect has been maintained for at least 18 months since starting the therapy.
