Pharmacist Review of Chronic Inhaler Therapy Appropriateness for Hospitalized Patients with COPD or Asthma.

INTRODUCTION: Patients with asthma and chronic obstructive pulmonary disease rely on inhaler therapy to reduce disease progression and exacerbation risk. Patients admitted to the hospital are at an increased risk for exacerbations and readmission if their inhaler therapy upon discharge is not aligned with current guidelines and/or affordable. OBJECTIVE: Assess the appropriateness of the chronic inhaler regimen for patients admitted to the hospital based on clinical practice guidelines and insurance coverage. METHODS: A sub-study was designed to analyze a cohort of a single-center, pragmatic, prospective randomized controlled trial at a large academic medical center. Patients admitted to a medicine service with a pharmacist and prescribed a long-acting inhaler were included. Participants randomized to a pharmacist-led intervention were assessed for inhaler appropriateness based on clinical guidelines and patient insurance. The objective of this sub-study is to assess the number of inhalers identified as inappropriate based on the pharmacist's review. A patient was considered to have an inappropriate inhaler regimen if any of their inhalers were inconsistent with guideline recommendations or not covered by insurance. Descriptive statistics were used to characterize appropriate inhaler use. RESULTS: The study pharmacist reviewed 552 unique inhalers for 348 patients. Overall, 42% of inhalers were inappropriate, affecting 50.3% of participants. 20% of inhalers were inappropriate based on insurance, 26% were inappropriate based on guidelines, and 7% were inappropriate based on both criteria. Recommendations were placed via a pharmacy consult for 198 patients (57%), most recommending an inhaler initiation (55%), followed by inhaler discontinuation (38%). CONCLUSION: A pharmacist-led review of chronic inhaler therapy for patients admitted to the hospital identified the need for a change in therapy based on financial or clinical guidelines in over half of the patients reviewed. Interventions to increase the appropriateness of prescribed inhalers are needed to reduce disease progression and disease exacerbation.

Efficacy of mupirocin, neomycin and octenidine for nasal Staphylococcus aureus decolonisation: a retrospective cohort study.

BACKGROUND: Periprosthetic joint infection (PJI) causes significant morbidity. Methicillin sensitive Staphylococcus aureus (MSSA) is the most frequent organism, and the majority are endogenous. Decolonisation reduces PJIs but there is a paucity of evidence comparing treatments. Aims; compare 3 nasal decolonisation treatments at (1) achieving MSSA decolonisation, (2) preventing PJI. METHODS: Our hospital prospectively collected data on our MSSA decolonisation programme since 2013, including; all MSSA carriers, treatment received, MSSA status at time of surgery and all PJIs. Prior to 2017 MSSA carriers received nasal mupirocin or neomycin, from August 2017 until August 2019 nasal octenidine was used. RESULTS: During the study period 15,958 primary hip and knee replacements were performed. 3200 (20.1%) were MSSA positive at preoperative screening and received decolonisation treatment, 698 mupirocin, 1210 neomycin and 1221 octenidine. Mupirocin (89.1%) and neomycin (90.9%) were more effective at decolonisation than octenidine (50.0%, P < 0.0001). There was no difference in PJI rates (P = 0.452). CONCLUSIONS: Mupirocin and neomycin are more effective than octenidine at MSSA decolonisation. There was poor correlation between the MSSA status after treatment (on day of surgery) and PJI rates. Further research is needed to compare alternative MSSA decolonisation treatments.

Surveillance recommendations for patients with Lynch syndrome and FAP : a monocentric study.

BACKGROUND AND STUDY AIMS: The most important causes of hereditary colorectal cancer are Lynch syndrome (LS) and the adenomatous polyposis syndromes (familial adenomatous poly- posis syndrome or FAP, attenuated FAP or AFAP and MUTYH associated polyposis syndrome or MAP). The aim of this study was to investigate whether all patients with a hereditary syndrome within one center receive uniform advice regarding surveillance and treatment. PATIENTS AND METHODS: A retrospective analysis was performed of all electronic patient health records of patients with LS, FAP, AFAP and MAP who received genetic counselling or were followed by a health care specialist at the University Hospital in Ghent. RESULTS: Data from 122 patients were collected. For all patients, recommendations from the medical genetics department were highly consistent. Adherence to their recommendations was good within the center for the management of colon polyps. There was a lack of consistency in the screening and surveillance advice for other tumors in departments other than gastroenterology. Only 33 patients had systematic follow-up consultations to check results and organize surveillance. CONCLUSION: Previously, small studies have suggested that patients with hereditary gastrointestinal cancer syndromes infrequently have surveillance as specified in the guidelines. This study shows almost uniform recommendations and good adherence for surveillance of the colon, but incomplete or contradictory advice for surveillance of other organs. The need for an integrated approach from a multidisciplinary team will only increase in the future, because more families with hereditary cancer are likely to be found due to the increased use of next generation sequencing in cancer diagnostics.

Effect of the Smart Moms intervention on targeted mediators of change in child sugar-sweetened beverage intake.

OBJECTIVE: Few parent-targeted interventions have examined the mechanisms of action by which the intervention changes child behavior. The purpose of this study was to test the theoretical and behavioral mediators of the Smart Moms intervention on changes in child sugar-sweetened beverage and juice (SSB/juice) consumption. STUDY DESIGN: This is a secondary mediation analysis of data from a 6-month randomized controlled trial (N = 51 mother-child dyads) of a mobile phone-based program to reduce child SSB/juice intake compared with a waitlist control group. METHODS: Linear mixed models compared changes in intervention targets from baseline to 3 months between treatment groups. Intervention targets that changed significantly between groups were tested in a multiple mediation model to evaluate their significance as mediators of change in child SSB/juice at 6 months. RESULTS: Maternal beverage consumption but no other behavioral or theoretical intervention targets mediated the effect of the intervention on the reduction in child SSB/juice at 6 months. There were few mediators of the intervention on child SSB/juice change. CONCLUSION: Greater longitudinal research is needed to understand predictors of child dietary changes to inform future intervention efforts. In addition, a greater focus on the measurement of theoretical constructs in family-based child obesity prevention research is needed.

Influence of plume advection and particle settling on wastewater dispersion and distribution.

Oceanographic processes are examined and used to assess their effect on the movement and dilution of wastewater discharged from Sydney's three deepwater ocean outfalls. Such processes link wastewater discharges with observed changes in biological communities and the accumulation of contaminants in the sediments. The East Australian Current, coastal trapped waves and local winds contribute 40%, 20% and 10% respectively to the total spectral energy in the along-shore currents off Sydney. Median dilutions at the edge of the initial dilution zone range between 185:1 and 347:1. Plumes remain submerged 95% of the time, surfacing only in the middle of winter and during large storms. Negatively buoyant particles sink from the plumes and first reach the ocean floor within 10 km of the discharge location. Resuspension of the sediments due to currents occurs 2.5% of the time and due to waves 1%-4% of the time.

Sustaining eHealth engagement in a multi-year weight gain prevention intervention.

INTRODUCTION: Digital tools are widely used and effective in weight management interventions; however, usage declines over time. Strategies to promote continued engagement should be explored. We examined the effects of offering additional modes of weight reporting as well as periodic online campaigns to promote engagement, assessed by frequency of weight reporting, in a weight gain prevention study for young adults. METHODS: Using an observational design, self-reported weights obtained through digital tools were pooled across participants assigned to two interventions (n = 312). Analysis examined the effects before during and after introduction of an additional reporting modality (email) and for three time-limited refresher campaigns over 2 years. RESULTS: Adding a new modality to the three existing modes (SMS, web, and mobile web) increased weight reporting as well as the number of modalities participants used to report weights. The use of several modes of reporting was associated with more weights submitted (p < 0.01). Refresher campaigns did not increase the proportion of participants reporting; however, the number of weights submitted during the 4-week campaigns increased compared with the 4 weeks before the campaign (p's ≥ 0.45, <0.001, respectively). CONCLUSION: Using multiple digital modalities and periodic campaigns shows promise for sustaining engagement with weight reporting in a young adult population, and incorporating such strategies may mitigate typical declines in eHealth and mHealth interventions.

'Ripple' effect on infant zBMI trajectory of an internet-based weight loss program for low-income postpartum women.

BACKGROUND: Weight loss interventions can have positive 'ripple' effects on untreated partners in the home, but ripple effects on infants are unknown. OBJECTIVE: To examine whether a 12-month internet-based weight loss intervention for postpartum mothers had a positive ripple effect on participants' infants. METHODS: A 12-month cluster randomized, assessor-blind, clinical trial enrolling 371 postpartum women at 12 Women, Infants, Children clinics in CA. Clinics were randomized to standard Women, Infants, Children or an internet-based weight loss intervention for mothers. RESULTS: A total of 333 of the 371 (89.8%) mothers assented for infant participation. Infants were 5.3 ± 3.2 months; 75.9% were Hispanic and 64% were breastfeeding. Infant retention was 272/333 (82.7%) at 6 months post enrollment and 251/333 (75.3%) at 12 months post enrollment. In intent-to-treat analysis, a significant interaction between group and time was observed (p = 0.008) with the offspring of intervention mothers exhibiting lower zBMI change from study entry through 6 months (0.23 [CI, 0.03, 0.44] vs. 0.65 [0.50, 0.79] zBMI change, respectively; p = 0.001) but was not significant through 12 months (p = 0.16). Regardless of group, maternal reports at the final assessment indicated that infants (aged =17.2 ± 3.4 months) consumed sweetened beverages (0.93 ± 1.5/week), juice (2.0 ± 1.4/day), 'junk food' (7.8 ± 5.4/week) and fast food (2/month), and 46.7% of the infants had a TV in their bedroom. CONCLUSIONS: An internet-based weight loss program for low-income, postpartum mothers had a positive 'ripple' effect on the zBMI of infants in the home during the first 6 months of treatment.

Weight gain prevention buffers the impact of CETP rs3764261 on high density lipoprotein cholesterol in young adulthood: The Study of Novel Approaches to Weight Gain Prevention (SNAP).

BACKGROUND AND AIMS: Two weight gain prevention strategies, one targeting small changes to diet and physical activity and a second targeting large changes, significantly reduced weight gain in young adulthood. We examined whether weight gain prevention blunts genetic risk for body weight increase and/or high density lipoprotein cholesterol (HDL-C) lowering over two years. METHODS AND RESULTS: Participants were 524 male and female young adults (mean age = 28.2, SD = 4.3; mean BMI = 25.5, SD = 2.6). Obesity-related SNPs accounting for ≥ 0.04% of the variance were genotyped and combined into a genetic risk score. For HDL-C, SNPs within CETP, LIPC and FADS2 were genotyped. The obesity-related genetic risk score did not predict change in BMI independently or in interaction with treatment arm. However, consistent with the prior literature, each copy of the HDL-C risk, C, allele at CETP rs3764261 was associated with lower HDL-C at baseline. Moreover, significant interaction between SNP and treatment arm for change in HDL-C was observed (p = 0.02). In the control group, HDL-C change was dependent upon rs3764261 (p = 0.004) with C allele carriers showing a continued reduction in HDL-C. In contrast, within the two intervention groups, HDL-C increased on average with no differential effect of rs3764261 (p > 0.24). Notably, even among carriers of the CC genotype, small and large change arms were associated with increased HDL-C and the control arm a reduction (p = 0.013). CONCLUSIONS: The C allele at CETP rs3764261 is a strong risk factor for low HDL-C in young adulthood but weight gain prevention may mitigate this risk.

Together Eating & Activity Matters (TEAM): results of a pilot randomized-clinical trial of a spousal support weight loss intervention for Black men.

Objectives: The objective of this study is to evaluate the feasibility, participation, preliminary efficacy and retention in a couples-based weight loss intervention among Black men. Design setting participants: Two-arm pilot randomized clinical trial in an academic clinical setting. Forty self-identified Black men and their female cohabitating partners (n = 80) aged 18 to 65 years with body mass index from 25 to 45 kg/m2 were randomized using computer generated tables to allocate treatments. Intervention: Participants were randomized to a standard behavioural weight loss (Standard) programme or the Standard programme plus partner involvement (Enhanced). Both interventions focused on calorie reduction, physical activity and self-monitoring to facilitate weight loss. Enhanced included couples skills training and couple's communication components. Main outcome and measures: Changes in weight from baseline to 3 months among men. Partner weight loss (secondary). Results: Forty Black couples (men mean [SD] age, 47.4[11] years; body mass index, 35.0[6.1]), were recruited. Retention was 100% of the men and 98% of female partners. Attendance at group sessions was 63-73%. Between groups, mean (SD) weight changes among men were -3.4[.04] and -4.7[5.9] kg (p = 0.57) and among women -0.23[4.46] and -2.47[3.62] kg (p = 0.09), in the standard and enhanced groups. Conclusions: Weight losses from an intervention enhanced by partner involvement and an intervention with no partner involvement were not different. Treatment choice can be based on preference rather than outcome as both treatments are effective in producing clinically significant percent weight loss.Trial registration Clinical Trials NCT02458053.

Clinical Evaluation of Tavocept to Decrease Diuresis Time and Volume in Dogs with Bladder Cancer Receiving Cisplatin.

BACKGROUND: Transitional cell carcinoma is the most common bladder cancer of dogs. Cisplatin combined with piroxicam provides superior response rates, but unacceptable rates of nephrotoxicity. Tavocept is a chemoprotectant that has mitigated cisplatin toxicity and decreased the required infusion/diuresis volume in clinical trials in humans. HYPOTHESIS/OBJECTIVES: We hypothesized that Tavocept would decrease diuresis volume and time and facilitate safe administration of a cisplatin/piroxicam protocol to dogs with bladder cancer. Secondary objectives were to compare response rate and survival times to an historical comparator group treated without Tavocept. ANIMALS: Fourteen client-owned dogs were prospectively enrolled. METHODS: Tumor volume was measured by computed tomography at days 0, 42, and 84. Dogs received combination Tavocept/cisplatin with a shortened diuresis protocol. A total of 4 doses was planned, with concurrent administration of piroxicam. Serial biochemical analyses were evaluated for azotemia. RESULTS: A 90-minute infusion/diuresis time was used for all dogs. Three dogs (21%) had concurrent increases in serum creatinine (>2.0 mg/dL) and BUN (>42 mg/dL) concentrations; 2 of these dogs were isosthenuric. This frequency of nephrotoxicity is significantly less (P = 0.0406) than that of an historical control group treated without Tavocept. Overall response rate was 27%. Median survival time was comparable to historical controls (253 vs. 246 days). CONCLUSIONS AND CLINICAL IMPORTANCE: Tavocept decreased the required diuresis time with cisplatin from > 6 hours to 90 minutes, while also decreasing occurrence of azotemia. Survival time was comparable, but the response rate was inferior to an historical comparator group. Further evaluation in other tumors susceptible to platinum agents is warranted.

A mHealth randomized controlled trial to reduce sugar-sweetened beverage intake in preschool-aged children.

BACKGROUND: Sugar-sweetened beverages and maternal weight are strong drivers of child obesity, but few studies have targeted these risk factors as an obesity prevention strategy in children. OBJECTIVE: The objective of this study was to test the efficacy of a smartphone-delivered intervention to reduce parent-provided sugar-sweetened beverage and juice (SSB/juice) consumption among children ages 3-5 and maternal weight. METHODS: Mothers with overweight or obesity, who had a child ages 3-5 that consumed at least 12 fl. oz./day of SSB/juice (N = 51 dyads) were randomized to the Smart Moms group that received one group session, lessons on a mobile website, and text messages, or to a waitlist control group. Mothers self-monitored their children's beverages in addition to their own beverages, high-calorie foods, and weight. Assessments at baseline, 3, and 6 months included dietary recalls to measure SSB/juice intake and objectively measured maternal weight. RESULTS: Using linear mixed models controlling for baseline values, child age and race, there was a greater reduction in child SSB/juice in Smart Moms compared with control at 6 months (-9.7 oz./day vs. 1.7 oz./day, p < .01). Mothers in Smart Moms lost 2.4 kg at 6 months compared with a 0.9-kg gain in the control group (p < .01). CONCLUSIONS: An intervention delivered using mHealth technologies can target mothers to change child dietary behaviours and improve maternal weight, which suggests a novel approach to family-based obesity prevention.

Weight loss and frequency of body-weight self-monitoring in an online commercial weight management program with and without a cellular-connected 'smart' scale: a randomized pilot study.

Objective: Evaluate the effects of an online commercial weight management program, with and without provision of a 'smart' scale with instructions to weigh daily and weekly tailored feedback, on weight loss and the frequency of body-weight self-monitoring. Methods: Participants (N = 92; body mass index 27-40 kg/m2) were randomized to 6 months of no-cost access to the Weight Watchers Online (WWO) platform alone, or enhanced with a cellular-connected 'smart' scale, instructions to weigh daily and weekly pre-scripted email feedback (Weight Watchers Online Enhanced [WWO-E]). The number of days that weight was self-monitored (via 'smart' scale in WWO-E and manually in WWO) was recorded automatically across the 6-month trial. Objective weight was measured at baseline, 3 and 6 months. Results: While both groups achieved statistically significant weight loss, mean ± standard error weight loss did not differ between WWO-E and WWO at 3 months (5.1 ± 0.6 kg vs. 4.0 ± 0.7 kg, respectively; p = 0.257) or 6 months (5.3 ± 0.6 kg vs. 3.9 ± 0.7 kg, respectively; p = 0.116). However, a greater proportion of WWO-E lost ≥5% of initial body weight at 3 months (52.2% vs. 28.3%; p = 0.033), but not 6 months (43.5% vs. 30.4%; p = 0.280), compared with WWO. Mean ± standard deviation days with self-monitored weight was higher in WWO-E (80.5 ± 5.6; 44.7% of days) than WWO (12.0 ± 1.0; 6.7% of days; p < 0.001) across the 6-month study period. Conclusions: This is the first study to show that provision of a 'smart' scale with weekly tailored feedback substantially increased the frequency of self-weighing and the proportion of participants achieving an initial clinically significant ≥5% weight loss (52% vs. 28%) in an online commercial weight management program. Both WWO and WWO-E produced significant weight loss over 6 months. While mean weight losses were slightly greater in the enhanced group, the difference was not statistically significant in this small sample. This study provides support for the clinical utility of online commercial weight management programs and the potential for supporting technology such as 'smart' scales to improve adherence to body-weight self-monitoring and clinical outcomes.

Frequency of self-weighing and weight loss outcomes within a brief lifestyle intervention targeting emerging adults.

BACKGROUND: Frequent self-weighing is associated with better weight loss and maintenance among adults. Emerging adults ages 18-25 rarely enroll in behavioural weight loss trials, and thus, little is known about their willingness to engage in frequent self-weighing and its association with weight loss in this age group. PURPOSE: The purpose of this study is to examine the frequency of self-weighing among 18-25-year-old over the course of a brief lifestyle intervention and to determine the association between frequent self-weighing and weight loss. METHODS: Emerging adults (EA) ages 18-25 [N = 52, 54% racial/ethnic minority, 79% female, BMI = 34.2 (5.4)] enrolled in a 3-month lifestyle intervention with structure and content modified for EA. Benefits of frequent self-weighing were presented; participants were encouraged to weigh themselves at least weekly and no more than daily. Assessments occurred at baseline and post-treatment (3 months). RESULTS: At baseline, a majority of participants (63.5%) reported self-weighing less than once a week. Frequency of self-weighing increased over treatment (p < 0.001), with 42.9% weighing weekly and 38.2% weighing several times per week or more (i.e. frequent self-weighing) at 3 months. Frequent self-weighing was associated with greater weight loss (p = 0.03) and greater likelihood of achieving 5% weight loss (p = 0.01) at post-treatment. CONCLUSIONS: Frequent self-weighing may be a viable approach to promoting self-regulation during the high-risk developmental period of emerging adulthood. Consistent with findings among other adult samples, frequent self-weighing was associated with greater weight losses.

A mixed methods approach to improving recruitment and engagement of emerging adults in behavioural weight loss programs.

OBJECTIVE: Emerging adults ages 18-25 are at high risk for obesity, but are markedly underrepresented in behavioural weight loss (BWL) programs and experience lower engagement and retention relative to older adults. PURPOSE: To utilize a mixed methods approach to inform future efforts to effectively recruit and engage this high-risk population in BWL programs. METHODS: We used a convergent parallel design in which quantitative and qualitative data were given equal priority. Study 1 (N = 137, age = 21.8 + 2.2, BMI = 30.1 + 4.7) was a quantitative survey, conducted online to reduce known barriers and minimize bias. Study 2 (N = 7 groups, age = 22.3 + 2.2, BMI = 31.5 + 4.6) was a qualitative study, consisting of in person focus groups to gain greater depth and identify contextual factors unable to be captured in Study 1. RESULTS: Weight loss was of interest, but weight itself was not a central motivation; an emphasis on overall lifestyle, self-improvement and fitness emerged as driving factors. Key barriers were time, motivation and money. Recruitment processes should be primarily online with messages tailored specifically to motivations and preferences of this age group. Preferences for a program were reduced intensity and brief, hybrid format with some in-person contact, individual level coaching, experiential learning and peer support. Key methods of promoting engagement and retention were autonomy and choice, money and creating an optimal default. CONCLUSIONS: An individually tailored lifestyle intervention that addresses a spectrum of health behaviours, promotes autonomy and emphasizes activity and fitness may facilitate recruitment and engagement in this population better than traditional BWL protocols.

Tasting profile affects adoption of caloric beverage reduction in a randomized weight loss intervention.

OBJECTIVE: The aim of this study was to examine differences in rates of non-caloric beverage adoption by participants classified as sweet likers (SLs) or sweet dislikers (measured using a behavioural tasting task). METHODS: Data are a sub-study from a 6-month, three-group, randomized weight loss trial (CHOICE) (body mass index 36.3 ± 5.8 kg m-2, 84% female, aged 42.2 ± 10.9 years, 53% African-American) comparing the replacement of caloric beverages with either non-caloric sweetened beverages (diet) or water (water) compared with a control group. This sub-study, which included participants within the water (n = 106) and diet (n = 103) groups only, examined whether SLs (n = 33 water; n = 37 diet) varied in their adherence to caloric beverage recommendations compared with sweet dislikers (n = 73 water; n = 76 diet) over the 6-month study. RESULTS: Diet intake and sweet-liking data collected on 190 (3 months) and 169 participants (6 months) were used for analysis. The interaction between SL status and beverage group (diet vs. water) approached significance (P = 0.06) at 3 months but not 6 months. Caloric beverage intake (% energy) at 3 months was significantly higher in SLs within the water group (9.7 ± 1.4%) compared with SLs in the diet group (5.4 ± 1.0%, P = 0.03). CONCLUSIONS: Results suggest that SL status may affect the rate in reduction of caloric beverages when water is the recommended substitution. Future studies should explore tailoring beverage recommendations to tasting profile.

Development of the International Spinal Cord Injury Activities and Participation Basic Data Set.

STUDY DESIGN: Consensus decision-making process. OBJECTIVES: The objective of this study was to develop an International Spinal Cord Injury (SCI) Activities and Participation (A&P) Basic Data Set. SETTING: International working group. METHODS: A committee of experts was established to select and define A&P data elements to be included in this data set. A draft data set was developed and posted on the International Spinal Cord Society (ISCoS) and American Spinal Injury Association websites and was also disseminated among appropriate organizations for review. Suggested revisions were considered, and a final version of the A&P Data Set was completed. RESULTS: Consensus was reached to define A&P and to incorporate both performance and satisfaction ratings. Items that were considered core to each A&P domain were selected from two existing questionnaires. Four items measuring activities were selected from the Spinal Cord Independence Measure III to provide basic data on task execution in activities of daily living. Eight items were selected from the Craig Handicap Assessment and Reporting Technique to provide basic data on the frequency of participation. An additional rating of satisfaction on a three-point scale for each item completes the total of 24 A&P variables. CONCLUSION: Collection of the International SCI A&P Basic Data Set variables in all future research on SCI outcomes is advised to facilitate comparison of results across published studies from around the world. Additional standardised instruments to assess activities of daily living or participation can be administered, depending on the purpose of a particular study.

Effects of fluoroquinolone restriction (from 2007 to 2012) on resistance in Enterobacteriaceae: interrupted time-series analysis.

BACKGROUND: Antibiotic stewardship is a key component in the effort to reduce healthcare-associated infections. AIM: To describe the implementation and analyse the impact of fluoroquinolone restriction on resistance in Enterobacteriaceae, focusing on urinary isolates of extended-spectrum ß-lactamase (ESBL)-producing Escherichia coli, which were historically almost universally resistant to fluoroquinolones. METHODS: ESBL-producing E. coli hospital and community isolates, obtained between April 2009 and March 2012 from consecutive non-duplicate urine samples, were included in an interrupted time-series analysis based on a Poisson distribution model. Periods before and after fluoroquinolone restriction were compared. The trend in fluoroquinolone resistance in all urinary isolates of Enterobacteriaceae (N ≈ 20,000 per year) and blood culture isolates of E. coli (N ≈ 350) between 2009 and 2013 were also analysed. FINDINGS: A large decline in the percentage of ciprofloxacin-resistant ESBL-producing urinary E. coli isolates was observed in both hospital (risk ratio: 0.473; 95% confidence interval: 0.315-0.712) and community settings (0.098; 0.062-0.157). The decline was also marked in all urinary isolates of Enterobacteriaceae and E. coli isolates from blood cultures. CONCLUSION: We conclude that reducing fluoroquinolone usage to a level of ≤2 defined daily doses per 100 occupied bed-days in hospital sufficiently removed selection pressure to allow resistant Enterobacteriaceae ­ specifically, the UK endemic strains of ESBL-producing E. coli ­ to revert back to fluoroquinolone susceptibility within a short span of four months. This was accompanied with a concomitant reduction in overall ESBL burden.

Effects of fluoroquinolone restriction (from 2007 to 2012) on Clostridium difficile infections: interrupted time-series analysis.

BACKGROUND: Antimicrobial stewardship is a key component in the reduction of healthcare-associated infections, particularly Clostridium difficile infection (CDI). We successfully restricted the use of cephalosporins and, subsequently, fluoroquinolones. From an endemically high level of >280 cases per year in 2007-08, the number of CDIs reduced to 72 cases in 2011-12. AIM: To describe the implementation and impact of fluoroquinolone restriction on CDI. METHODS: This was an interrupted time-series analysis pre and post fluoroquinolone restriction for 60 months based on a Poisson distribution model. FINDINGS: In June 2008, fluoroquinolone consumption halved to about 5 defined daily doses (DDD) per 100 occupied bed-days (OBD). This was followed by a significant fall in CDI number [rate ratio (RR): 0.332; 95% confidence interval (CI): 0.240-0.460] which remained low over the subsequent months. Subsequently, fluoroquinolone consumption was further reduced to about 2 DDD/100 OBD in June 2010 accompanied by further reduction in CDI rate (RR: 0.394; 95% CI: 0.199-0.781). In a univariate Poisson model the CDI rate was associated with fluoroquinolone usage (RR: 1.086; 95% CI: 1.077-1.094). CONCLUSION: We conclude that in an environment where cephalosporin usage is already low, the reduction in fluoroquinolone usage was associated with an immediate, large, and significant reduction in CDI cases.

Society for Maternal-Fetal Medicine (SMFM) Clinical Guideline #8: the fetus at risk for anemia: diagnosis and management

OBJECTIVE: We sought to provide evidence-based guidelines for the diagnosis and management of fetal anemia. METHODS: A systematic literature review was performed using MEDLINE, PubMed, EMBASE, and the Cochrane Library. The search was restricted to English-language articles published from 1966 through May 2014. Priority was given to articles reporting original research, in particular randomized controlled trials, although review articles and commentaries were consulted. Abstracts of research presented at symposia and scientific conferences were not considered adequate for inclusion. Evidence reports and published guidelines were also reviewed, and additional studies were located by reviewing bibliographies of identified articles. GRADE (Grading of Recommendations Assessment, Development, and Evaluation) methodology was used for defining the strength of recommendations and rating the quality of evidence. Consistent with US Preventive Task Force guidelines, references were evaluated for quality based on the highest level of evidence. RESULTS AND RECOMMENDATIONS: We recommend the following: (1) middle cerebral artery peak systolic velocity (MCA-PSV) measured by ultrasound Doppler interrogation be used as the primary technique to detect fetal anemia; (2) amniotic fluid delta OD450 not be used to diagnosis fetal anemia; (3) MCA-PSV assessment be reserved for those patients who are at risk of having an anemic fetus (proper technique for MCA-PSV evaluation includes assessment of the middle cerebral artery close to its origin, ideally at a zero degree angle without angle correction); (4) if a fetus is deemed at significant risk for severe fetal anemia (MCA greater than 1.5 multiples of the median or hydropic), fetal blood sampling be performed with preparation for an intrauterine transfusion, unless the pregnancy is at a gestational age when the risks associated with delivery are considered to be less than those associated with the procedure; (5) if a fetus is deemed at significant risk for severe fetal anemia, the patient be referred to a center with expertise in invasive fetal therapy; (6) MCA-PSV be considered to determine the timing of a second transfusion in fetuses with anemia, and, alternatively, a predicted decline in fetal hemoglobin may be used for timing the second procedure; and (7) pregnancies with a fetus at significant risk for fetal anemia be delivered at 37-38 weeks of gestation unless indications develop prior to this time.(AU)
