Repetitive Transcranial Magnetic Stimulation Promotes Rapid Psychiatric Stabilization in Acutely Suicidal Military Service Members.

OBJECTIVE: This study presents data for using accelerated transcranial magnetic stimulation (TMS) as an intervention for suicidal crisis (SC). METHODS: This prospective, single-site, randomized, double-blind trial enrolled active-duty military participants with SC to receive either active TMS (n = 59) or sham TMS (n = 61) 3 times per day for 3 consecutive days. Our primary outcome, the Beck Scale for Suicidal Ideation-current (SSI-C), was measured before each session of TMS. Secondary outcomes measured both the SSI-C and the Beck Scale for Suicidal Ideation-total daily for the 3 intervention days and at 1, 3, and 6 months of follow-up. RESULTS: In the modified intention to treat (mITT) analysis of SSI-C changes over treatment sessions, the TMS active group had accelerated decline in suicidal ideation as compared with sham: ß for interaction was 0.12 points greater SSI-C decline per session (standard error [SE], 0.06) in TMS versus sham (P = 0.04). In both the mITT and per-protocol active TMS groups, the mean final SSI-C scores were below 3. These scores remained below 3 for the entire 6-month follow-up period. CONCLUSIONS: In this military trial of suicidal patients, we found that both active and sham accelerated TMS rapidly reduces SC. Moreover, in the mITT analysis, there was a statistically significant antisuicidal benefit of active TMS versus sham TMS in the primary outcome. Both the mITT and per-protocol groups moved from higher to approximately 7 times lower suicide risk strata and remained there for the duration of the study. Further studies are warranted to understand accelerated TMS' full potential as a treatment for SC.

The impact of the face-to-face consultation on decisional conflict in complex decision-making in multiple sclerosis: A pilot study.

BACKGROUND: The role of face-to-face consultations in medicine is increasingly being challenged. Disease activity, national guidelines, life goals e.g. pregnancy, multiple therapies and side effects need to be considered on starting disease modifying treatments (DMTs) in people with multiple sclerosis (pwMS). OBJECTIVES: We studied the impact of a face-to-face consultation on decision making, using decisional conflict (DC) as the primary outcome. METHODS: Prospective cohort study of 73 pwMS attending clinics who were making decisions about DMTs followed for one year. Prerequisites and consultation features were measured with the SURE scale for DC used as the primary outcome at baseline and at one year. RESULTS: The patient activation measure (PAM) was the only driver prior to the consultation associated with DC (p = 0.02) showing those less engaged were more likely to have DC. Overall, 51/73 (70%) of people made their treatment decision or reinforced a former decision during the consultation. We found making a treatment decision between the original consultation and the follow-up was associated with resolving DC (p = 0.008). CONCLUSIONS: Patient engagement impacts DC but the HCP delivering the optimal Shared Decision Making (SDM) approach is additionally significant in reducing DC. In complex decisions there is a clear role for face-to-face consultations in current practice.

An interdisciplinary intensive outpatient pain program is associated with improved patient activation and key outcomes.

Aim: To examine the change in the Patient Activation Measure and physical and psychosocial outcome measures in a military interdisciplinary intensive outpatient program for persistent pain. Materials & methods: Pre- and post-intervention measures, which were also stratified by gender and baseline activation, included patient-reported outcomes and physical function assessment, obtained from 2017 to 2018 program database. Results: The majority of the participants were male (70.9%), with an average age of 29.18 years and pain duration of 4.78 years (n = 103). Patient activation, majority of the patient reported outcomes and functional assessments improved in the overall sample with fewer changes in females on the Defense and Veterans Pain Rating Scale. Conclusion: Improvements were noted on the Patient Activation Measure and majority of the other outcome measures suggesting that service members with persistent pain at any level of patient activation or baseline function, may benefit from an intensive outpatient program.

Preliminary report of postoperative complications of phacoemulsification in Pugs: A multicenter retrospective study of 32 cases.

OBJECTIVE: To compare complication rates and visual outcomes following phacoemulsification in Pugs versus dogs of other breeds. ANIMALS STUDIED: Thirty-two pure-bred Pugs (55 eyes) and 32 dogs of other breeds (56 eyes) undergoing phacoemulsification. PROCEDURES: Multi-institutional retrospective medical record review of perioperative factors, postoperative complications, and visual outcomes. The reference population of dogs of varying breeds included surgical cases following each Pug case at the same institutions. Perioperative risk factors and postoperative complication rates were compared between the two populations. RESULTS: Pigmentary keratitis and diabetes mellitus were the most common preoperative comorbidities, found in 75% (P < .001) and 72% (P = .12) of Pugs, respectively. No perioperative factors were significantly associated with postoperative complications in Pugs. Postoperative complication rates were similar between groups; however, the most common complication in Pugs was corneal ulceration (15% of operated eyes), whereas glaucoma was most common in the reference population (13% of operated eyes). Three months postoperatively, vision was preserved in 91% of eyes of Pugs (50/55) and 95% of the reference population (53/56). One year postoperatively, 80% (32/40) of Pug eyes and 82% (28/34) of eyes in the reference population remained sighted. CONCLUSIONS: Comorbidities and complications of cataract surgery in Pugs of this study demonstrate a predisposition for corneal disease. This highlights the importance of preoperative evaluation of factors associated with PK and corneal clarity, and postoperative monitoring for corneal ulceration in this breed.

Strengthen causal models for better conservation outcomes for human well-being.

BACKGROUND: Understanding how the conservation of nature can lead to improvement in human conditions is a research area with significant growth and attention. Progress towards effective conservation requires understanding mechanisms for achieving impact within complex social-ecological systems. Causal models are useful tools for defining plausible pathways from conservation actions to impacts on nature and people. Evaluating the potential of different strategies for delivering co-benefits for nature and people will require the use and testing of clear causal models that explicitly define the logic and assumptions behind cause and effect relationships. OBJECTIVES AND METHODS: In this study, we outline criteria for credible causal models and systematically evaluated their use in a broad base of literature (~1,000 peer-reviewed and grey literature articles from a published systematic evidence map) on links between nature-based conservation actions and human well-being impacts. RESULTS: Out of 1,027 publications identified, only ~20% of articles used any type of causal models to guide their work, and only 14 total articles fulfilled all criteria for credibility. Articles rarely tested the validity of models with empirical data. IMPLICATIONS: Not using causal models risks poorly defined strategies, misunderstanding of potential mechanisms for affecting change, inefficient use of resources, and focusing on implausible efforts for achieving sustainability.

"I Will Respect the Autonomy of My Patient": A Scoping Review of Shared Decision Making in Multiple Sclerosis.

BACKGROUND: Patient autonomy is a bioethical principle that was strengthened in the revised Declaration of Geneva. Shared decision making (SDM) is particularly relevant in the management of multiple sclerosis (MS) because many preference-sensitive decisions have to be made during the disease course. We aimed to summarize the available evidence on SDM in the MS field and to inform future research and practice. METHODS: We performed a scoping review by searching MEDLINE (past 5 years). Studies were included if they reported primary/secondary research and focused on SDM related to people with MS. Data were grouped into topics, with results presented in narrative form. RESULTS: From 865 references, we included 55 studies conducted mostly in Europe. Half of the studies were observational, followed by qualitative (20%), mixed-methods (17%), randomized controlled trials (RCTs, 5%), quasi-experimental (5%), and reviews (4%). Most studies addressed people with relapsing-remitting MS (85%); the remaining addressed health care professionals, patients' significant others, or a combination. We identified five main topics: decisions on disease-modifying drugs, decisions on chronic cerebrospinal venous insufficiency treatment, information provision and patient education, health literacy, and risk knowledge. CONCLUSIONS: The high proportion of included studies on SDM in MS in Europe suggests an earlier adoption of these concepts in this area. Decisions on disease-modifying drugs was the prevalent topic. Only 5% of studies were RCTs, indicating that more research is needed to study the effectiveness of SDM interventions. Studies addressing people with primary and secondary progressive MS are also needed.

Determination of trypan blue efficacy in the mitigation of ex vivo canine PCO formation.

PURPOSE: To determine whether trypan blue (TB) reduces canine lens epithelial cell (LEC) or corneal endothelial cell (CEC) viability in vitro; if cell death is noted, to subsequently evaluate the molecular mechanism. METHODS: Cellular viability was determined using a lactate dehydrogenase (LDH) assay. In TB-treated LECs, caspase 3/7 activity was assessed to evaluate apoptosis; autophagy was evaluated using immunoblotting against LC3 and p62. To evaluate the effects of TB on ex vivo posterior capsule opacification (PCO), following mock cataract surgery, lens capsules were treated with TB and subsequently maintained in culture to determine LEC migration and proliferation. RESULTS: Following acute exposure, TB did not significantly reduce LEC or CEC viability at any of the concentrations tested. Increased caspase 3/7 activity was found in LEC cultures treated with TB for an extended period of time; no change in LC3 or p62 expression was noted. Ex vivo PCO formation was not significantly altered by TB treatment. CONCLUSIONS: Acute exposure to TB did not reduce LEC or CEC viability, and only longer exposure to TB was able to initiate apoptosis. Treatment with intraocular TB at the time of cataract surgery is likely safe to the CECs but will not prevent PCO formation.

Effects of grape seed extract, lutein, and fish oil on responses of canine lens epithelial cells in vitro.

OBJECTIVE To determine the effects of grape seed extract (GSE), lutein, and fish oil containing omega-3 fatty acids on oxidative stress, migration, proliferation, and viability of lens epithelial cells (LECs). SAMPLE Lens capsules or cultured LECs obtained from canine cadavers. PROCEDURES An antioxidant reductive capacity assay was used to determine reducing capability of each substance. The LECs were cultured and incubated with various substances, including N-acetyl cysteine (NAC), when appropriate, and dimethyl sulfoxide (DMSO) as positive and vehicle control substances, respectively. A dichlorofluorescein assay was used to evaluate reactive oxygen species (ROS) production, and a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was used to determine cell viability. Ex vivo posterior capsule opacification (PCO) was used to evaluate LEC migration and proliferation. RESULTS Antioxidant reductive effects of GSE surpassed those of NAC, lutein, and fish oil containing omega-3 fatty acids. The GSE reduced ROS production in LECs, compared with the DMSO vehicle control, whereas lutein was pro-oxidative. All test substances reduced cell viability. Ex vivo PCO was not altered by GSE, was decreased by lutein, and was increased by fish oil containing omega-3 fatty acids, compared with results for the DMSO vehicle control. CONCLUSIONS AND CLINICAL RELEVANCE Only GSE had significant antioxidant capabilities and reduced ROS production; however, no effect on ex vivo PCO was detected. Fish oil containing omega-3 fatty acids increased ex vivo PCO. No conclusions could be made regarding antioxidant effects of these substances on LECs. These findings suggested that the substances will not decrease PCO.

The Neuroprotective and antioxidative effects of submicron and blended Lycium barbarum in experimental retinal degeneration in rats.

The object is to determine the neuroprotective and antioxidative effects of submicron and blended Lycium barbarum (LB) on retinal degeneration as evaluated by ERG, retinal histopathology and assays of antioxidant (total GSH) and peroxidant (MDA) in the retina. A rat model of light-induced retinal degeneration was used to assess the protective effect of different forms of Lycium barbarum (LB) on retinal degeneration. Rats were divided into four experimental groups, normal control, light-induced untreated, submicron LB and blended LB treated. The rats of submicron and blended groups were treated with 250 mg/kg LB orally once daily for 54 days, followed by induction of retinal degeneration. Retinal function was assessed by electroretinography (ERG). Enzyme-linked immunosorbent assay of the retina lysates was measured for the levels of antioxidants, reduced glutathione and glutathione disulfide, and peroxidants, malondialdehyde, in the retina. The ERG results showed a protective effect in LB treated groups with a greater effect observed in submicron LB treated group than the blended LB treated group. There were higher levels of GSH plus GSSG and lower MDA in submicron LB treated group than other groups. In conclusion, LB provided protective and antioxidative effects on the rat retina with light-induced retinal degeneration. Submicron LB protected degenerative retina better than blended LB. LB is effective against oxidative stress in the degenerative retina.

The exceptional value of intact forest ecosystems.

As the terrestrial human footprint continues to expand, the amount of native forest that is free from significant damaging human activities is in precipitous decline. There is emerging evidence that the remaining intact forest supports an exceptional confluence of globally significant environmental values relative to degraded forests, including imperilled biodiversity, carbon sequestration and storage, water provision, indigenous culture and the maintenance of human health. Here we argue that maintaining and, where possible, restoring the integrity of dwindling intact forests is an urgent priority for current global efforts to halt the ongoing biodiversity crisis, slow rapid climate change and achieve sustainability goals. Retaining the integrity of intact forest ecosystems should be a central component of proactive global and national environmental strategies, alongside current efforts aimed at halting deforestation and promoting reforestation.

Use of an intravenous sclerosing foam (3% sodium tetradecyl sulfate) for treatment of orbital varix in a dog.

A 6-month-old intact male Standard Dachshund was referred for evaluation of a soft tissue swelling above the right eye. Examination of the right eye revealed mild lateral deviation of the globe, normal vision, and a dorsonasal soft tissue swelling. Examination of the posterior segment was normal. Dual-phase computed tomography angiography was consistent with an orbital varix of the angularis oculi and right dorsal external ophthalmic veins with no evidence of arterial involvement. Treatment involved fluoroscopically guided coil embolization of the venous outflow with nine platinum microcoils, followed by sclerotherapy of the varix using 1.5 mL of 3% sodium tetradecyl sulfate foam. Moderate-to-marked swelling was noted at the treatment site in the weeks following therapy, which gradually resolved. At final reexamination 3 months post-therapy, complete sclerosis and resolution of the orbital varix were documented. To the authors' knowledge, this is the first reported case involving the use of a sclerotic agent for successful treatment of a venous malformation in a dog.

No. 248-Guidelines for the Evaluation and Treatment of Recurrent Urinary Incontinence Following Pelvic Floor Surgery.

OBJECTIVE: To provide general gynaecologists and urogynaecologists with clinical guidelines for the management of recurrent urinary incontinence after pelvic floor surgery. OPTIONS: Evaluation includes history and physical examination, multichannel urodynamics, and possibly cystourethroscopy. Management includes conservative, pharmacological, and surgical interventions. OUTCOMES: These guidelines provide a comprehensive approach to the complicated issue of recurrent incontinence that is based on the underlying pathophysiological mechanisms. EVIDENCE: Published opinions of experts, and evidence from clinical trials where available. VALUES: The quality of the evidence is rated using the criteria described by the Canadian Task Force on Preventive Health Care (Table).

Effect of high-dose simvastatin on cognitive, neuropsychiatric, and health-related quality-of-life measures in secondary progressive multiple sclerosis: secondary analyses from the MS-STAT randomised, placebo-controlled trial.

BACKGROUND: In the 24-month MS-STAT phase 2 trial, we showed that high-dose simvastatin significantly reduced the annualised rate of whole brain atrophy in patients with secondary progressive multiple sclerosis (SPMS). We now describe the results of the MS-STAT cognitive substudy, in which we investigated the treatment effect on cognitive, neuropsychiatric, and health-related quality-of-life (HRQoL) outcome measures. METHODS: We did a secondary analysis of MS-STAT, a 24-month, double-blind, controlled trial of patients with SPMS done at three neuroscience centres in the UK between Jan 28, 2008, and Nov 4, 2011. Patients were randomly assigned (1:1) to either 80 mg simvastatin (n=70) or placebo (n=70). The cognitive assessments done were the National Adult Reading Test, Wechsler Abbreviated Scale of Intelligence, Graded Naming Test, Birt Memory and Information Processing Battery (BMIPB), Visual Object and Space Perception battery (cube analysis), Frontal Assessment Battery (FAB), and Paced Auditory Serial Addition Test. Neuropsychiatric status was assessed using the Hamilton Depression Rating Scale and the Neuropsychiatric Inventory Questionnaire. HRQoL was assessed using the self-reported 36-Item Short Form Survey (SF-36) version 2. Assessments were done at study entry, 12 months, and 24 months. Patients, treating physicians, and outcome assessors were masked to treatment allocation. Analyses were by intention to treat. MS-STAT is registered with ClinicalTrials.gov, number NCT00647348. FINDINGS: Baseline assessment revealed impairments in 60 (45%) of 133 patients on the test of frontal lobe function (FAB), and in between 13 (10%) and 43 (33%) of 130 patients in tests of non-verbal and verbal memory (BMIPB). Over the entire trial, we noted significant worsening on tests of verbal memory (T score decline of 5·7 points, 95% CI 3·6-7·8; p<0·0001) and non-verbal memory (decline of 6·8 points, 4·8-8·7; p<0·0001). At 24 months, the FAB score was 1·2 points higher in the simvastatin-treated group than in the placebo group (95% CI 0·2-2·3). The simvastatin group also had a 2·5 points better mean physical component score of the SF-36 (95% CI 0·3-4·8; p=0·028). A treatment effect was not noted for any other outcomes. INTERPRETATION: To our knowledge, this SPMS cohort is the largest studied to date with comprehensive longitudinal cognitive, neuropsychiatric, and HRQoL assessments. We found evidence of a positive effect of simvastatin on frontal lobe function and a physical quality-of-life measure. Although we found no effect of simvastatin on the other outcome measures, these potential effects warrant confirmation and underline the importance of fully assessing cognition and quality of life in progressive multiple sclerosis treatment trials.

Glaucoma with Descemet's membrane detachment in five horses.

PURPOSE: To describe the clinical and histopathologic features of glaucoma associated with Descemet's membrane (DM) detachment in five horses without prior history of intraocular surgery. ANIMALS STUDIED: Three Appaloosa horses and two Thoroughbreds were included in this study. The affected horses ranged in age from 16 to 27 years and presented with severe diffuse corneal edema. PROCEDURE: Five eyes were enucleated due to intraocular hypertension and/or chronic corneal ulceration. The enucleated globes were evaluated by the Comparative Ocular Pathology Laboratory of Wisconsin (COPLOW). Each globe was routinely processed for histopathology and analyzed by light microscopy. A histologic diagnosis of glaucoma was reached by demonstrating a loss of optic nerve axonal tissue by measuring neurofilament-immunopositive axons with automated image analysis software. RESULTS: All five horses presented with unilateral severe diffuse corneal edema that had developed between 2 and 16 weeks prior to enucleation. Intraocular pressures for the affected eyes were between 9 and 87 mmHg prior to enucleation. Descemet's membrane detachment was identified histopathologically in all five globes (5/5, 100%). All five eyes had an avascular spindle cell proliferation filling the space between the displaced peripheral DM and the corneal stroma. Neurofilament immunostaining revealed axonal loss consistent with glaucoma. CONCLUSION: Equine glaucoma may be associated with Descemet's membrane detachment. This detachment and glaucoma is a possible differential diagnosis for severe equine corneal edema. In this case series, an eye with a DM detachment had a poor prognosis for retention.

Heat-shock protein 70 expression in the equine cornea.

OBJECTIVE: Expression of the 70-kDa heat-shock protein (HSP70) has been demonstrated in normal canine corneal epithelium, and inducible expression has been suggested to facilitate wound resolution through organized migration, proliferation, and adhesion of the corneal epithelial cells. Diminished expression of HSP70 may therefore contribute to prolonged healing in the pathologic cornea of other companion animal species, including the horse. ANIMAL STUDIED: Normal and pathologic equine cornea was evaluated to determine whether the expression of HSP70 is correlated with appropriate corneal epithelial wound healing. PROCEDURES: Paraffin-embedded tissue from normal equine cornea and therapeutic keratectomies of sterile keratopathies was subject to routine immunohistochemistry for HSP70. RESULTS: Normal equine corneas exhibited the baseline expression of HSP70 in the nuclei of all epithelial cells as well as the cytoplasm of the basal epithelium. Expression of HSP70 in suspected immune-mediated keratitis was localized to the cytoplasm of basal epithelial cells and nuclei of all epithelial cells, similar to the normal equine cornea. Expression in indolent ulcers was diminished; weak, diffuse staining was noted in the cytoplasm of all epithelial cells. CONCLUSIONS: These findings suggest the expression of HSP70 is induced in the normal equine cornea during re-epithelialization and may be altered in sterile keratopathies.

An association between systemic cyclosporine administration and development of acute bullous keratopathy in cats.

OBJECTIVE: To determine whether any association exists between the onset of feline acute bullous keratopathy (ABK) and administration of systemic corticosteroid or immunosuppressive therapy. ANIMALS STUDIED: Medical records of cats diagnosed with ABK between the years of 2000 and 2008 were retrospectively reviewed. Breed, age at diagnosis, weight, systemic disease status, eye affected, ophthalmic examination findings, systemic and topical therapy instituted, dosage and duration of therapy, visual outcome and histopathological analyses were recorded in cases meeting the inclusion criteria. RESULTS: A total of 12 cats of a surveyed population of 70 167 met the inclusion criteria with 17/24 eyes affected by ABK. Medical and/or surgical therapy was utilized for management of ABK with 13/17 eyes remaining sighted at the time of last follow-up. In a subset of cases corneal cytology, aerobic bacterial culture, FHV-1 PCR, virus isolation and/or histopathology were performed; no infectious organisms were identified. A rupture in Descemet's membrane of the cornea was identified histologically in two globes. A total of 10 of 12 cats had been previously diagnosed with ongoing systemic disease. A total of 10 of 12 cats were receiving systemic therapy, and a significant association (P < 0.001) was noted between systemic administration of corticosteroids and/or cyclosporine A and the development of ABK. A total of 8 of 10 cats were administered oral prednisolone at doses between 1-2 mg/kg every 12-24 h. A total of 5 of 8 cats receiving oral prednisolone were concurrently administered oral cyclosporine at doses of 1.5-7 mg/kg every 12-24 h. Systemic cyclosporine therapy was found to be a significant risk factor (P < 0.001) for ABK development, while systemic prednisolone was not significant (P = 0.10). CONCLUSIONS: Systemic cyclosporine administration appears to be a risk factor for development of ABK in the population of cats studied.

Obstetrical Anal Sphincter Injuries (OASIS): Prevention, Recognition, and Repair.

OBJECTIVE: To review the evidence relating to obstetrical anal sphincter injuries (OASIS) with respect to diagnosis, repair techniques and outcomes. To formulate recommendations as to patient counselling regarding route of delivery for subsequent pregnancy after OASIS. OPTIONS: Obstetrical care providers caring for women with OASIS have the option of repairing the anal sphincter using end-to-end or overlapping techniques. They may also be involved in counselling women with prior OASIS regarding the route of delivery for future pregnancies. OUTCOMES: The outcome measured is anal continence following primary OASIS repair and after subsequent childbirth. EVIDENCE: Published literature was retrieved through searches of Medline, EMBASE, and The Cochrane Library in May 2011 using appropriate controlled vocabulary (e.g., anal canal, obstetrics, obstetric labour complication, pregnancy complication, treatment outcome, surgery, quality of life) and key words (obstetrical anal sphincter injur*, anus sphincter, anus injury, delivery, obstetrical care, surgery, suturing method, overlap, end-to-end, feces incontinence). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational. There were no date or language restrictions. Searches were updated on a regular basis and incorporated in the guideline to September 2014. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. VALUES: The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). BENEFITS, HARMS, AND COSTS: Benefits from implementation of these guidelines include: improved diagnosis of OASIS, optimal functional outcomes following repair, and evidence-based counselling of women for future childbirth.

Objectif : Analyser les données probantes traitant des lésions obstétricales du sphincter anal (LOSA) en ce qui concerne leur diagnostic, les techniques visant leur réparation et les résultats de l'intervention. Formuler des recommandations permettant d'éclairer les conseils offerts aux patientes ayant connu des LOSA en ce qui a trait à la voie d'accouchement à privilégier dans le cadre des grossesses subséquentes. Options : Les fournisseurs de soins obstétricaux qui comptent des patientes ayant connu des LOSA disposent de l'option de réparer le sphincter anal en faisant appel à la méthode de suture « bout à bout ¼ (end-to-end) ou à la méthode « en paletot ¼ (overlapping). Ils pourraient également être appelés à conseiller des femmes ayant déjà connu des LOSA en ce qui a trait à la voie d'accouchement à privilégier pour les grossesses subséquentes. Issues : Le critère d'évaluation était la continence anale à la suite d'une réparation primaire de LOSA et à la suite d'un accouchement subséquent. Résultats : La littérature publiée a été récupérée par l'intermédiaire de recherches menées dans Medline, EMBASE et The Cochrane Library en mai 2011 au moyen d'un vocabulaire contrôlé (p. ex. anal canal, obstetrics, obstetric labour complication, pregnancy complication, treatment outcome, surgery, quality of life) et de mots clés (p. ex. obstetrical anal sphincter injur*, anus sphincter, anus injury, delivery, obstetrical care, surgery, suturing method, overlap, end-to-end, feces incontinence) appropriés. Les résultats ont été restreints aux analyses systématiques, aux études observationnelles et aux essais comparatifs randomisés / essais cliniques comparatifs. Aucune restriction n'a été imposée en matière de date ou de langue. Les recherches ont été mises à jour de façon régulière et intégrées à la directive clinique jusqu'en septembre 2014. La littérature grise (non publiée) a été identifiée par l'intermédiaire de recherches menées dans les sites Web d'organismes s'intéressant à l'évaluation des technologies dans le domaine de la santé et d'organismes connexes, dans des collections de directives cliniques, dans des registres d'essais cliniques et auprès de sociétés de spécialité médicale nationales et internationales. Valeurs : La qualité des résultats a été évaluée au moyen des critères décrits dans le rapport du Groupe d'étude canadien sur les soins de santé préventifs (Tableau). Avantages, désavantages et coûts : Parmi les avantages de la mise en œuvre de la présente directive clinique, on trouve : l'amélioration du diagnostic des LOSA, l'obtention d'issues fonctionnelles optimales à la suite de la réparation et l'offre de conseils reposant sur des données probantes aux femmes en ce qui concerne leurs futures grossesses. Déclarations sommaires 1. Les lésions obstétricales du sphincter anal mènent à des comorbidités considérables, dont l'incontinence anale, les fistules rectovaginales et la douleur. (II-2) 2. Les lésions obstétricales du sphincter anal sont plus souvent associées aux accouchements par forceps qu'aux accouchements par ventouse obstétricale. (II-2) 3. Réparation des lésions obstétricales du sphincter anal : a. L'utilisation de polyglactin 2-0 ou de polydioxanone 3-0 donne lieu, après six semaines, à des taux semblables de morbidité liée aux sutures. (I) b. La réparation du sphincter anal interne est recommandée puisque les femmes chez lesquelles la présence d'une anomalie affectant ce sphincter est révélée au cours de l'échographie postpartum sont plus susceptibles de connaître une incontinence anale. (III) c. La réparation du sphincter anal externe devrait englober la gaine fasciale. Le recours à la technique de suture « en paletot ¼ (chevauchement) nécessite souvent une mobilisation et une dissection de plus grande envergure des extrémités du sphincter; l'utilisation de cette technique n'est possible qu'en présence de déchirures sphinctériennes de degré 3b ou plus. (III) d. La présence persistante d'une anomalie du sphincter anal externe longtemps après l'accouchement pourrait accroître le risque de voir apparaître une aggravation des symptômes à la suite des accouchements vaginaux subséquents. (II-2) 4. Les lésions obstétricales du sphincter anal sont associées à une hausse du risque de rétention urinaire postpartum. (II-2) 5. À la suite de la réparation réussie d'une lésion obstétricale du sphincter anal, la plupart des femmes peuvent connaître un accouchement vaginal en toute sûreté dans le cadre d'une grossesse subséquente. (III) 6. Services de counseling offerts aux femmes au sujet de leurs accouchements subséquents : a. Le risque de récurrence d'une lésion obstétricale du sphincter anal dans le cadre d'un accouchement subséquent est de 4-8 %. (II-2) b. On a calculé que, pour prévenir un cas d'incontinence anale chez des femmes ayant déjà subi une lésion obstétricale du sphincter anal, la tenue de 2,3 césariennes planifiées s'avérerait nécessaire, le tout s'accompagnant alors d'une hausse des risques maternels. (II-2) Recommandations 1. Toutes les femmes devraient faire l'objet d'un examen rigoureux visant la détection de déchirures périnéales ou vaginales; celles qui présentent une déchirure dont la profondeur est plus que superficielle devraient, avant la mise en œuvre d'une réparation, faire l'objet d'un examen rectal systématique cherchant à établir la présence de lésions obstétricales du sphincter anal. (II-2B) 2. Le système de classification de l'Organisation mondiale de la santé devrait être utilisé pour classer les lésions obstétricales du sphincter anal. Ce système permet l'établissement d'une distinction entre le degré de déchirure du sphincter externe (3a < 50 % ou 3b ≥ 50 %) et la présence d'anomalies du sphincter interne (3c). La présence d'une lésion en boutonnière (button-hole injury) constitue un incident distinct et devrait être classée en conséquence. (III-B) 3. Chez les femmes qui connaissent un accouchement vaginal spontané, le taux de lésions obstétricales du sphincter anal est amoindri lorsque le fournisseur de soins obstétricaux ralentit la tête fœtale au moment du dégagement. (II-2A) 4. Épisiotomie : a. Dans le cadre d'un accouchement vaginal spontané ou instrumental, le fournisseur de soins obstétricaux devrait, pour assurer la prévention des lésions obstétricales du sphincter anal, respecter une politique prévoyant une utilisation « restreinte ¼ de l'épisiotomie (c.-à-d. seulement lorsque cela s'avère indiqué), plutôt qu'une utilisation « libre ¼ de cette intervention (c.-à-d. de façon systématique). (I-A) b. Lorsque la tenue d'une épisiotomie est jugée indiquée, l'octroi d'une préférence envers la tenue d'une incision médiolatérale (plutôt qu'envers la tenue d'une incision médiane) devrait être envisagé. (II-2B) L'angle d'incision optimal semble être d'au moins 45 degrés (idéalement, aux alentours de 60 degrés). (II-2B) 5. La réparation peut être différée (pendant 8-12h) sans effets nuisibles. La mise en œuvre d'un délai pourrait s'avérer nécessaire jusqu'à ce que les services d'un fournisseur de soins disposant de l'expérience nécessaire pour procéder à la réparation puissent être retenus. (I-A) 6. L'administration prophylactique d'une dose intraveineuse unique d'antibiotiques (céphalosporine de 2e génération, p. ex. céfotétan ou céfoxitine) devrait être mise en œuvre pour assurer la baisse des taux de complications de lésion périnéale à la suite de la réparation des lésions obstétricales du sphincter anal. (I-A) 7. Des laxatifs (p. ex. lactulose) devraient être prescrits à la suite de la réparation primaire d'une lésion obstétricale du sphincter anal puisqu'ils sont associés à des premières selles moins douloureuses et survenant plus rapidement, et à l'obtention plus rapide du congé de l'hôpital. L'utilisation d'agents constipants et d'agents de gonflement n'est pas recommandée. (I-A) 8. Les anti-inflammatoires non stéroïdiens et l'acétaminophène sont les analgésiques de première intention. Les opioïdes ne devraient être utilisés qu'avec précaution. La constipation devrait être évitée au moyen d'un laxatif ou d'un émollient fécal. (1-A) 9. À la suite de la constatation d'une lésion obstétricale du sphincter anal, les fournisseurs de soins devraient divulguer à leurs patientes le degré de la lésion subie et prendre les dispositions nécessaires à la mise en œuvre d'un suivi. Il est nécessaire de procéder à la documentation détaillée de la lésion et de sa réparation. (III-L) 10. Les femmes qui connaissent une incontinence anale après avoir subi une lésion obstétricale du sphincter anal devraient être orientées vers des services de physiothérapie du plancher pelvien. (I-A).

Protected areas and poverty.

Protected areas are controversial because they are so important for conservation and because they distribute fortune and misfortune unevenly. The nature of that distribution, as well as the terrain of protected areas themselves, have been vigorously contested. In particular, the relationship between protected areas and poverty is a long-running debate in academic and policy circles. We review the origins of this debate and chart its key moments. We then outline the continuing flashpoints and ways in which further evaluation studies could improve the evidence base for policy-making and conservation practice.

Guiding principles for evaluating the impacts of conservation interventions on human well-being.

Measures of socio-economic impacts of conservation interventions have largely been restricted to externally defined indicators focused on income, which do not reflect people's priorities. Using a holistic, locally grounded conceptualization of human well-being instead provides a way to understand the multi-faceted impacts of conservation on aspects of people's lives that they value. Conservationists are engaging with well-being for both pragmatic and ethical reasons, yet current guidance on how to operationalize the concept is limited. We present nine guiding principles based around a well-being framework incorporating material, relational and subjective components, and focused on gaining knowledge needed for decision-making. The principles relate to four key components of an impact evaluation: (i) defining well-being indicators, giving primacy to the perceptions of those most impacted by interventions through qualitative research, and considering subjective well-being, which can affect engagement with conservation; (ii) attributing impacts to interventions through quasi-experimental designs, or alternative methods such as theory-based, case study and participatory approaches, depending on the setting and evidence required; (iii) understanding the processes of change including evidence of causal linkages, and consideration of trajectories of change and institutional processes; and (iv) data collection with methods selected and applied with sensitivity to research context, consideration of heterogeneity of impacts along relevant societal divisions, and conducted by evaluators with local expertise and independence from the intervention.
