Urinary tract infections in multiple sclerosis

BACKGROUND: Urinary tract infections (UTIs) are commonly reported by people with multiple sclerosis (PwMS) and significantly impact quality of life. OBJECTIVE: To provide an overview of the problem of UTIs in PwMS and offer a practical approach for the diagnosis and management. METHODS: A review of the literature through a Pubmed search up to October 2015 was performed using the following keywords: multiple sclerosis, neurogenic bladder, urinary tract infections, relapse, dipsticks, culture, recurrent and prevention. RESULTS: Noteworthy topics include the definition of a confirmed symptomatic UTI as a positive urine culture defined by >10(5) colony-forming units (CFU)/mL or >10(4) CFU/mL if a urethral catheter urine sample is taken, or any count of bacteria in a suprapubic bladder puncture specimen, both in addition to symptoms including fever, pain, changes in lower urinary tract symptoms or neurological status. Urinalysis is useful to exclude a UTI; however, on its own is insufficient to confirm a UTI, for which urine culture is required. Experts advise asymptomatic UTIs should not be treated except in the context of an acute relapse. From international guidelines, there is no validated strategy to prevent recurrent UTIs in PwMS. CONCLUSION: This review provides an overview of the diagnosis, treatment and prevention of UTIs in the setting of multiple sclerosis (MS)

The prevention and management of hospital admissions for urinary tract infection in patients with multiple sclerosis

Introduction Urinary tract infections (UTIs) are one of the commonest reasons for patients with multiple sclerosis (PwMS) presenting to hospital. Management of recurrent UTIs in PwMS can be challenging and characteristics of such patients are not well described. Aims To describe the neurological and urological features of PwMS presenting to hospital for UTIs and identify areas of management that could be improved to reduce UTI frequency. Methods Health episode statistics data were used to identify PwMS presenting to a tertiary hospital with UTI over a 5-year period. Medical records were reviewed for demographic, MS and urological history. The seven PwMS with the highest numbers of encounters were seen in a multidisciplinary clinic to enable detailed assessments. Results 52 PwMS (25 female, 27 male) with mean age of 60 had 112 emergency department presentations and 102 inpatient admissions for UTI. 24 presented multiple times and were more likely to be older and male with progressive MS. Almost two-thirds were using a urinary catheter. Less than half were under current urological and neurological follow-up. Escherichia coli and Pseudomonas spp were the commonest organisms cultured. Resistance to antibiotics was more frequent in patients with multiple presentations. Conclusions PwMS presenting to hospital for UTIs are more often male, older, with progressive MS and high levels of disability. A small group of PwMS accounted for a large number of encounters. Preventative and management strategies can be applied in primary and secondary care settings, with an emphasis on bladder, catheter and general physical care

Screening for urinary tract colonisation prior to corticosteroid administration in acute multiple sclerosis relapses: Validation of an updated algorithm

INTRODUCTION: To evaluate an updated algorithm in the detection of urinary tract infection (UTI) prior to high-dose corticosteroid treatment in acute relapses in multiple sclerosis (MS). This updated algorithm aimed to decrease the unnecessary use of antibiotics, whilst maintaining accuracy and safety. METHODS: Prospective cohort study of 471 consecutive patients with MS relapses in a hospital-based outpatient acute relapse clinic. 172 patients met exclusion criteria, leaving 299 patients for analysis. Patients underwent urine dipstick and were treated for UTI if 2 or more of: nitrites, leukocyte esterase and cloudy urine were positive. Patients with confirmed acute MS relapse were treated with high dose intravenous or oral methylprednisolone. RESULTS: Significant bacteriuria (>105 colony forming units/mL) was present in 33 (11%, 95% CI 8-15) patients. The algorithm sensitivity and specificity was 24% and 94% respectively; the negative predictive value was 91%. The overall accuracy of the algorithm was 87%. No adverse sequelae were identified in 25 patients who received high dose methylprednisolone in the presence of an untreated UTI. CONCLUSION: With an improved specificity, this updated algorithm addresses previous issues concerning the unnecessary prescription of antibiotics, whilst improving accuracy and maintaining safety

Open label feasibility study evaluating D-mannose combined with home-based monitoring of suspected urinary tract infections in patients with multiple sclerosis

Objective: To assess the feasibility of using D‐mannose, a natural food supplement, in patients with multiple sclerosis (MS) reporting recurrent urinary tract infections (UTIs) as a preventative. Methods: A single‐center, open‐label, feasibility study enrolled patients with MS, using and not using urinary catheters, experiencing recurrent UTIs (≥3/year or ≥2/6 months). Participants were given D‐mannose powder 1.5 grams twice daily for 16‐weeks and were instructed to monitor suspected UTIs at home using urine dipsticks. Diaries were used to record compliance, number of prescriptions of antibiotics received for UTIs, results of urine dipsticks and cultures. Results: Overall, 22 patients with MS, median age 50 years (46–59) were enrolled: 10 were not using catheters and 12 were using catheters. The compliance rates for using D‐mannose and dipsticks for testing suspected UTIs were 100% and 90.2%, respectively. Sixty‐one episodes of suspected UTIs were recorded, 19/61 (31.1%) were confirmed UTIs and 29/61 (47.5%) prescriptions of antibiotics were made. The number of monthly proven UTIs decreased both in catheter users and non‐users (P < 0.01). No adverse effects were reported. Conclusion: Using D‐mannose in patients with MS experiencing recurrent UTIs and self‐monitoring for infections is feasible and safe. Further studies are required to establish efficacy

Knowledge brokering between researchers and policymakers in Fiji to develop policies to reduce obesity: a process evaluation

The importance of using research evidence in decision making at the policy level has been increasingly recognized. However, knowledge brokering to engage researchers and policymakers in government and non-government organizations is challenging. This paper describes and evaluates the knowledge exchange processes employed by the Translational Research on Obesity Prevention in Communities (TROPIC) project that was conducted from July 2009 to April 2012 in Fiji. TROPIC aimed to enhance: the evidence-informed decision making skills of policy developers; and awareness and utilization of local and other obesity-related evidence to develop policies that could potentially improve the nation&rsquo;s food and physical activity environments. The specific research question was: Can a knowledge brokering approach advance evidence-informed policy development to improve eating and physical activity environments in Fiji. <br /

Spina bifida-predisposing heterozygous mutations in Planar Cell Polarity genes and Zic2 reduce bone mass in young mice

Fractures are a common comorbidity in children with the neural tube defect (NTD) spina bifida. Mutations in the Wnt/planar cell polarity (PCP) pathway contribute to NTDs in humans and mice, but whether this pathway independently determines bone mass is poorly understood. Here, we first confirmed that core Wnt/PCP components are expressed in osteoblasts and osteoclasts in vitro. In vivo, we performed detailed µCT comparisons of bone structure in tibiae from young male mice heterozygous for NTD-associated mutations versus WT littermates. PCP signalling disruption caused by Vangl2 (Vangl2Lp/+) or Celsr1 (Celsr1Crsh/+) mutations significantly reduced trabecular bone mass and distal tibial cortical thickness. NTD-associated mutations in non-PCP transcription factors were also investigated. Pax3 mutation (Pax3Sp2H/+) had minimal effects on bone mass. Zic2 mutation (Zic2Ku/+) significantly altered the position of the tibia/fibula junction and diminished cortical bone in the proximal tibia. Beyond these genes, we bioinformatically documented the known extent of shared genetic networks between NTDs and bone properties. 46 genes involved in neural tube closure are annotated with bone-related ontologies. These findings document shared genetic networks between spina bifida risk and bone structure, including PCP components and Zic2. Genetic variants which predispose to spina bifida may therefore independently diminish bone mass

Financial crises and the attainment of the SDGs: an adjusted multidimensional poverty approach

This paper analyses the impact of financial crises on the Sustainable Development Goal of eradicating poverty. To do so, we develop an adjusted Multidimensional Poverty Framework (MPF) that includes 15 indicators that span across key poverty aspects related to income, basic needs, health, education and the environment. We then use an econometric model that allows us to examine the impact of financial crises on these indicators in 150 countries over the period 1980–2015. Our analysis produces new estimates on the impact of financial crises on poverty’s multiple social, economic and environmental aspects and equally important captures dynamic linkages between these aspects. Thus, we offer a better understanding of the potential impact of current debt dynamics on Multidimensional Poverty and demonstrate the need to move beyond the boundaries of SDG1, if we are to meet the target of eradicating poverty. Our results indicate that the current financial distress experienced by many low-income countries may reverse the progress that has been made hitherto in reducing poverty. We find that financial crises are associated with an approximately 10% increase of extreme poor in low-income countries. The impact is even stronger in some other poverty aspects. For instance, crises are associated with an average decrease of government spending in education by 17.72% in low-income countries. The dynamic linkages between most of the Multidimensional Poverty indicators, warn of a negative domino effect on a number of SDGs related to poverty, if there is a financial crisis shock. To pre-empt such a domino effect, the specific SDG target 17.4 on attaining long-term debt sustainability through coordinated policies plays a key role and requires urgent attention by the international community

Effects among healthy subjects of the duration of regularly practicing a guided imagery program

BACKGROUND: We examined a large number of healthy adults in the general community who had individually participated in a guided imagery (GI) program daily and for various durations, to examine the psychophysiological effects of a GI program within a healthy group. METHODS: We studied 176 subjects who had participated in sessions that were part of a guided imagery program, and who had practiced GI at home for 20 minutes once daily in a quiet place after mastering GI in the group sessions. The average duration of GI practiced at home was 6.88 ± 14.06 months (n = 138, range: 0 to 72). The Multiple Mood Scale (MMS), Betts (1909) Shortened Questionnaire on Mental Imagery (QMI), and a visual analog scale (VAS) of imagery vividness, salivary cortisol (C(S)) levels, general stress and general health were used in the sessions. RESULTS: We examined the relationship between the duration of daily GI practiced at home and MMS, QMI, C(S), general health, and general stress at baseline. The subjects who had practiced GI at home longer had lower negative mood scores at baseline and lower severity of stress, and higher positive mood at baseline (both at a session and at home), general health, and QMI scores at baseline. The MMS change during a session and the duration of daily GI practiced at home were not correlated. Repeated-measures analysis of covariance showed that the duration of daily GI practiced as the covariate was not associated with changes in the three C(S )levels. CONCLUSION: Although regularly practicing a GI program daily for 20 min did not affect the C(S )level or mood during a GI session for several hours, it kept a good condition of the general mental, physical well-being and their overall stress of the practitioners as they had practiced it for long duration. We postulate that subjects who have the high ability of imaging vividness showed the better mood, health status and less stress than those subjects who have the low ability of it did. The ability of image vividness of the long-term regular practitioners of GI was higher than its short-term or inexperienced practitioners, which allowed practitioners to produce more comfortable imagery. Consequently, the longer the duration that they had practiced GI program once a day regularly, the lower scores of their stress were and the higher scores of their health were. We suggest that the regular daily practice of a GI program might be connected to less stress and better health

Fish and fishing in the Roman world

This article focuses on two aspects related to fish and fishing. It first discusses the social context for the consumption of preserved and fresh fish, showing that generally consumption of certain types of fresh fish conferred status, whereas consumption of preserved fish, being more affordable, was attested across social strata. The paper then moves on to examine the organization of the ‘fishing industry’, specifically the relationship between fish-salting establishments and the fishermen who provided the fish. Although we have many literary, documentary, and archaeological sources for fish preservation and fishing techniques in classical antiquity, the fishermen engaged in large-scale fishing remain rather elusive
