Comparative Effectiveness of Anti-TNF in Combination With Low-Dose Methotrexate vs Anti-TNF Monotherapy in Pediatric Crohn's Disease: A Pragmatic Randomized Trial.

BACKGROUND & AIMS: Tumor necrosis factor inhibitors, including infliximab and adalimumab, are a mainstay of pediatric Crohn's disease therapy; however, nonresponse and loss of response are common. As combination therapy with methotrexate may improve response, we performed a multicenter, randomized, double-blind, placebo-controlled pragmatic trial to compare tumor necrosis factor inhibitors with oral methotrexate to tumor necrosis factor inhibitor monotherapy. METHODS: Patients with pediatric Crohn's disease initiating infliximab or adalimumab were randomized in 1:1 allocation to methotrexate or placebo and followed for 12-36 months. The primary outcome was a composite indicator of treatment failure. Secondary outcomes included anti-drug antibodies and patient-reported outcomes of pain interference and fatigue. Adverse events (AEs) and serious AEs (SAEs) were collected. RESULTS: Of 297 participants (mean age, 13.9 years, 35% were female), 156 were assigned to methotrexate (110 infliximab initiators and 46 adalimumab initiators) and 141 to placebo (102 infliximab initiators and 39 adalimumab initiators). In the overall population, time to treatment failure did not differ by study arm (hazard ratio, 0.69; 95% CI, 0.45-1.05). Among infliximab initiators, there were no differences between combination and monotherapy (hazard ratio, 0.93; 95% CI, 0.55-1.56). Among adalimumab initiators, combination therapy was associated with longer time to treatment failure (hazard ratio, 0.40; 95% CI, 0.19-0.81). A trend toward lower anti-drug antibody development in the combination therapy arm was not significant (infliximab: odds ratio, 0.72; 95% CI, 0.49-1.07; adalimumab: odds ratio, 0.71; 95% CI, 0.24-2.07). No differences in patient-reported outcomes were observed. Combination therapy resulted in more AEs but fewer SAEs. CONCLUSIONS: Among adalimumab but not infliximab initiators, patients with pediatric Crohn's disease treated with methotrexate combination therapy experienced a 2-fold reduction in treatment failure with a tolerable safety profile.

Microbiome-derived metabolites in early to mid-pregnancy and risk of gestational diabetes: a metabolome-wide association study.

BACKGROUND: Pre-diagnostic disturbances in the microbiome-derived metabolome have been associated with an increased risk of diabetes in non-pregnant populations. However, the roles of microbiome-derived metabolites, the end-products of microbial metabolism, in gestational diabetes (GDM) remain understudied. We examined the prospective association of microbiome-derived metabolites in early to mid-pregnancy with GDM risk in a diverse population. METHODS: We conducted a prospective discovery and validation study, including a case-control sample of 91 GDM and 180 non-GDM individuals within the multi-racial/ethnic The Pregnancy Environment and Lifestyle Study (PETALS) as the discovery set, a random sample from the PETALS (42 GDM, 372 non-GDM) as validation set 1, and a case-control sample (35 GDM, 70 non-GDM) from the Gestational Weight Gain and Optimal Wellness randomized controlled trial as validation set 2. We measured untargeted fasting serum metabolomics at gestational weeks (GW) 10-13 and 16-19 by gas chromatography/time-of-flight mass spectrometry (TOF-MS), liquid chromatography (LC)/quadrupole TOF-MS, and hydrophilic interaction LC/quadrupole TOF-MS. GDM was diagnosed using the 3-h, 100-g oral glucose tolerance test according to the Carpenter-Coustan criteria around GW 24-28. RESULTS: Among 1362 annotated compounds, we identified 140 of gut microbiome metabolism origin. Multivariate enrichment analysis illustrated that carbocyclic acids and branched-chain amino acid clusters at GW 10-13 and the unsaturated fatty acids cluster at GW 16-19 were positively associated with GDM risk (FDR < 0.05). At GW 10-13, the prediction model that combined conventional risk factors and LASSO-selected microbiome-derived metabolites significantly outperformed the model with only conventional risk factors including fasting glucose (discovery AUC: 0.884 vs. 0.691; validation 1: 0.945 vs. 0.731; validation 2: 0.987 vs. 0.717; all P < 0.01). At GW 16-19, similar results were observed (discovery AUC: 0.802 vs. 0.691, P < 0.01; validation 1: 0.826 vs. 0.780; P = 0.10). CONCLUSIONS: Dysbiosis in microbiome-derived metabolites is present early in pregnancy among individuals progressing to GDM.

Communication Strategies to Improve Antibiotic Prescribing in Pediatric Urgent Care Centers.

OBJECTIVE: Urgent care (UC) clinicians frequently prescribe inappropriate antibiotics for upper respiratory illnesses. In a national survey, pediatric UC clinicians reported family expectations as a primary driver for prescribing inappropriate antibiotics. Communication strategies effectively reduce unnecessary antibiotics while increasing family satisfaction. We aimed to reduce inappropriate prescribing practices in otitis media with effusion (OME), acute otitis media (AOM), and pharyngitis in pediatric UC clinics by a relative 20% within 6 months using evidence-based communication strategies. METHODS: We recruited participants via e-mails, newsletters, and Webinars from pediatric and UC national societies. We defined antibiotic-prescribing appropriateness based on consensus guidelines. Family advisors and UC pediatricians developed script templates based on an evidence-based strategy. Participants submitted data electronically. We reported data using line graphs and shared deidentified data during monthly Webinars. We used χ 2 tests to evaluate change in appropriateness at the beginning and end of the study period. RESULTS: The 104 participants from 14 institutions submitted 1183 encounters for analysis in the intervention cycles. Using a strict definition of inappropriateness, overall inappropriate antibiotic prescriptions for all diagnoses trended downward from 26.4% to 16.6% ( P = 0.13). Inappropriate prescriptions trended upward in OME from 30.8% to 46.7% ( P = 0.34) with clinicians' increased use of "watch and wait" for this diagnosis. Inappropriate prescribing for AOM and pharyngitis improved from 38.6% to 26.5% ( P = 0.03) and 14.5% to 8.8% ( P = 0.44), respectively. CONCLUSIONS: Using templates to standardize communication with caregivers, a national collaborative decreased inappropriate antibiotic prescriptions for AOM and had downward trend in inappropriate antibiotic prescriptions for pharyngitis. Clinicians increased the inappropriate use of "watch and wait" antibiotics for OME. Future studies should evaluate barriers to the appropriate use of delayed antibiotic prescriptions.

Ethical uncertainty and COVID-19: exploring the lived experiences of senior physicians at a major medical centre.

Given the wide-reaching and detrimental impact of COVID-19, its strain on healthcare resources, and the urgent need for-sometimes forced-public health interventions, thorough examination of the ethical issues brought to light by the pandemic is especially warranted. This paper aims to identify some of the complex moral dilemmas faced by senior physicians at a major medical centre in Saudi Arabia, in an effort to gain a better understanding of how they navigated ethical uncertainty during a time of crisis. This qualitative study uses a semistructured interview approach and reports the findings of 16 interviews. The study finds that participants were motivated by a profession-based moral obligation to provide care during the toughest and most uncertain times of the pandemic. Although participants described significant moral dilemmas during their practice, very few identified challenges as ethical in nature, and in turn, none sought formal ethics support. Rather, participants took on the burden of resolving ethical challenges themselves-whenever possible-rationalising oft fraught decisions by likening their experiences to wartime action or by minimising attention to the moral. In capturing these accounts, this paper ultimately contemplates what moral lessons can, and must be, learnt from this experience.

Antibiotic Prescribing Patterns for Pediatric Urgent Care Clinicians.

OBJECTIVE: Previous studies have reported high rates of inappropriate antibiotic prescriptions in urgent care (UC). Specific prescribing patterns for the most common diagnoses are not known. The aim of the study is to determine the diagnoses for which antibiotics are prescribed in pediatric UC settings. METHODS: We recruited pediatric UC providers via email to participate in a national multisite quality improvement study. Participants completed a survey on 10 consecutive encounters in which an antibiotic was given between March and May 2018. Encounters in which only topical antibiotics were prescribed were excluded. We categorized the encounters into 3 previously established tiers to determine appropriateness of antibiotic use. The tiers represent a descending order for antibiotic need based on diagnoses, with the first tier representing diagnoses almost always requiring antibiotics and the third tier representing diagnoses when an antibiotic is almost never required. We reported the diagnoses and frequency of antibiotic prescription within each tier. RESULTS: The 157 providers from 20 institutions submitted a total of 2809 encounters. We excluded 339 encounters in which only topical antibiotics were prescribed. Most diagnoses fell into the tier 2 category (85.81%), with only 9.12% in tier 1 and 5.06% in tier 3. The most common diagnoses reported were acute otitis media (48.96%), pharyngitis (25.09%), and skin and soft tissue infections (7.29%). CONCLUSIONS: In this sample of pediatric UC encounters, only 5% of diagnoses receiving antibiotic prescriptions were made up of tier 3 diagnoses, determined to almost never require antibiotics. While viral respiratory infections have been reported to frequently be treated with antibiotics in general UC centers, our study of pediatric UC centers showed that this was infrequent. However, otitis media with effusion and otalgia should be further investigated. With most antibiotic prescriptions being tier 2 diagnoses, pediatric UC providers can use evidence-based prescribing practices, shared decision making, and contingency plans to reduce unnecessary antibiotic exposure.

Pediatric Urgent Care Providers' Approach to Antibiotic Stewardship: A National Survey.

BACKGROUND: Outpatient antibiotic prescribing for acute respiratory conditions is highest in urgent care settings; however, this has not been studied among pediatric urgent cares. The objective of this study was to evaluate pediatric urgent care providers' perceptions of antibiotic stewardship. METHODS: Members of the Society for Pediatric Urgent Care were recruited via email to participate in a quality improvement antibiotic stewardship project. A preimplementation survey was sent to participants via email in March 2019 to evaluate perceptions on antibiotic stewardship. Descriptive statistics were used to analyze the survey responses. RESULTS: A total of 156 providers completed the survey; 83% were board-certified pediatricians. Almost all (98%) indicated that antibiotic stewardship interventions are important for optimizing antibiotic use in urgent care. More than half (53%) indicated that their urgent care provided guidelines for prescribing antibiotics for acute respiratory tract infections. Treating patients with an underlying complex medical condition was the most common reason (21%) providers would deviate from guidelines. The most commonly cited barriers to appropriate prescribing for acute respiratory infections were patient expectations (93%), psychosocial barriers (40%), lack of clear evidence-based recommendations (15%), and lack of access to guidelines on prescribing (15%). CONCLUSIONS: Parental expectation of receiving antibiotics was viewed as the most common barrier to appropriate prescribing. These findings should be used to target directed interventions such as shared decision making and communication training to support appropriate antibiotic prescribing in pediatric urgent care.

Education vs Clinician Feedback on Antibiotic Prescriptions for Acute Respiratory Infections in Telemedicine: a Randomized Controlled Trial.

BACKGROUND: Antibiotics prescribed for acute respiratory tract infections in the telemedicine setting are often unwarranted. OBJECTIVE: We hypothesized that education plus individualized feedback, compared with education alone, would significantly reduce antibiotic prescription rates for upper respiratory infections, bronchitis, sinusitis, and pharyngitis in a telemedicine setting. DESIGN: Two-arm, parallel-group randomized controlled trial conducted at a telemedicine practice from January 1, 2018, to November 30, 2018. PARTICIPANTS: Clinicians employed at the practice on or after January 1, 2017 (n = 45). INTERVENTIONS: The control group received education (treatment guideline presentation and online course) in April 2018. The intervention group received education plus individualized feedback via an online dashboard with monthly rates of personal and practice-wide antibiotic prescription rates starting May 2018. MAIN MEASURES: Antibiotic prescription for any visit with at least one target condition: upper respiratory tract infection, bronchitis, sinusitis, and pharyngitis. KEY RESULTS: Baseline antibiotic prescription rates in control and intervention groups across conditions were as follows: upper respiratory infection (URI): 626/3410 (18.4%), 413/2752 (15.0%), bronchitis: 689/1471 (46.8%), 742/1162 (64.0%), sinusitis: 5154/6131 (84.1%), 4250/4876 (87.2%), pharyngitis: 2308/2838 (81.3%), 1593/2126 (74.9%). Antibiotic prescriptions for all conditions decreased in the post-intervention period compared with those in the pre-intervention period, for both control and intervention groups. Reduction of antibiotic prescriptions for URI and bronchitis was greater for the group receiving education plus individualized feedback compared with that for the group receiving education alone (interaction term ratio 0.60, 95% CI 0.47 to 0.77 for URI; and interaction term ratio 0.42, 95% CI 0.32 to 0.55 for bronchitis), but not sinusitis and pharyngitis. CONCLUSION: Education plus individualized feedback in a telemedicine practice significantly decreased antibiotic prescription rates for upper respiratory tract infections and bronchitis, compared with education alone. Future studies should focus on tailoring antibiotic stewardship programs based on underlying conditions, and the maintenance of early reductions in antibiotic prescription.

Determinants of nutritional status during the first 1000 days of life in Lebanon: Sex of the child matters.

BACKGROUND: The first 1000 days of life support child growth and long-term health, but few studies address this period in Lebanon and the Eastern Mediterranean Region. OBJECTIVE: To examine the determinants of nutritional status among Lebanese children ≤2 years old by child's sex. METHODS: We analysed data from a nationally representative cross-sectional survey of 466 mother-child dyads. We classified socio-economic, maternal, and child characteristics using a hierarchical conceptual framework into distal, intermediate, and proximal levels, respectively. Sex-stratified weighted multiple linear regression was computed to identify the determinants of length-for-age z-scores (LAZ) and weight-for-length z-scores (WLZ). RESULTS: The mean (standard deviation) of LAZ and WLZ was -0.3 (1.6) and 0.5 (1.5) among boys and -0.1 (1.4) and 0.5 (1.0) among girls, respectively. At the distal level, maternal intermediate or high school education was associated with higher boys' LAZ (ß 1.0, 95% confidence interval (CI) 0.2, 1.8), and less crowded households were associated with higher girls' LAZ (ß 0.8, 95% CI 0.3, 1.4). At the intermediate level, maternal obesity was associated with lower girls' LAZ (ß -0.9, 95% CI -1.4, -0.4). At the proximal level, birth length directly (ß 0.1, 95% CI 0.0, 0.2) and breast-feeding duration inversely (ß -0.1, 95% CI -0.1, -0.0) associated with girls' LAZ. For WLZ, paternal attainment of university degree or technical diploma was associated with lower boys' WLZ (ß -0.9, 95% CI -1.8, -0.1). Among the proximal determinants, birthweight was directly associated with boys' WLZ (ß 1.2, 95% CI 0.6, 1.8), while being a third or later child was associated with lower girls' WLZ (ß -0.5, 95% CI -0.8, -0.2). Child age was directly associated with WLZ among boys and girls (ß 0.1, 95% CI 0.0, 0.1). CONCLUSIONS: Nutritional status determinants differed by child's sex in Lebanon. These findings may help inform interventions to improve child growth.

Q-Switched Nd:YAG (532 nm) Laser Versus Intra-Dermal Tranexamic Acid for Treatment of Facial Ephelides: A Split Face, Randomized, Comparative Trial.

BACKGROUND AND OBJECTIVES: To compare the efficacy and safety of intradermal injection of tranexamic acid (TXA) versus Q switched (QS) KTP (532 nm) in the treatment of facial ephelides. STUDY DESIGN/MATERIALS AND METHODS: A randomized comparative split-face study included a total of 30 female patients with bilateral facial ephelides. One cheek was treated by intra-dermal TXA injections and the other was treated by QS-KTP (532 nm). Patient assessment was performed by photography, pigmentation area, severity index and spectrophotometry at baseline, 1 week after treatment, and 2 months after treatment. RESULTS: A significant difference was found between both sides regarding the percentage change of pigmentation area, severity score (PSI) and melanin index (MI) after treatment and during follow up, favoring laser (P = 0.001). PSI decreased after treatment by 66.5% and 15.4% (laser and TXA sides respectively), further decrease after follow-up was 69.4% with laser and 26.1% with TXA. MI improved by 3.7% after KTP laser to 7.7% after follow-up and by 2.4% after TXA injections to 6.5% after follow-up. Four patients developed post-inflammatory hyperpigmentation following QS-KTP. CONCLUSION: QS-KTP laser is superior to intradermal TXA injection in the treatment of facial ephelides. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

Combining Low Power Fractional CO2 With QS-NdYAG Toning in the Treatment of Melasma Reduces the Incidence of Punctate Leukoderma.

BACKGROUND AND OBJECTIVES: Q-switched Nd:YAG (QS-Nd:YAG) toning (low fluence, large spot size, and high frequency) has been used successfully for the treatment of melasma, especially in dark skin phototypes. Punctate leukoderma was found to be a frequent complication that reduced the safety of this procedure. Combining low power fractional CO2 laser, which is another effective melasma laser therapy, might improve the efficacy and safety of this procedure. The aim of this study was to evaluate  the effect of combining low power fractional CO2 laser with QS-Nd:YAG toning in the treatment of melasma. STUDY DESIGN/MATERIALS AND METHODS: A randomized comparative split-face study included a total of 30 patients with bilateral, symmetrical melasma. All patients received QS-Nd:YAG toning on one randomly selected side of the face, while the other side randomly received either low power fractional CO2 alone (group A) or combined QS-Nd:YAG toning with low power fractional CO2 (group B). QS-Nd:YAG toning sessions were scheduled every two weeks for nine consecutive sessions, and low power fractional CO2 sessions were received every 4 weeks for three consecutive sessions. The assessment was done using the modified melasma area and severity index (mMASI) score, spectrophotometry (melanin index [MI] and erythema index [EI]), photography, blinded physician assessment, and patient satisfaction (at baseline, 1 week and 8-12 weeks after the last treatment sessions). RESULTS: A significant reduction in the mMASI score and MI was obtained with all treatment regimens. On comparing different modalities, group A reduction in mMASI and MI was significantly greater on the side receiving QS-ND:YAG toning (64.03% and 8.27%, respectively), than the side receiving low power fractional CO2 laser alone (36.02%. 2.64%, respectively). On the other hand, reduction of mMASI score and MI showed no statistical significance between the side receiving QS-Nd:YAG toning alone and the combined modality. Punctate leukoderma occurred in four cases (13%) on the side receiving QS-Nd:YAG toning. CONCLUSION: QS-Nd:YAG toning is significantly more effective than low power fractional CO2 in the treatment of melasma when used separately. Although combining low power fractional CO2 with QS-Nd:YAG toning does not increase its efficacy, it minimizes the incidence of the undesirable punctate leukoderma complication and achieves lower recurrence. This combination can thus be recommended as a safe and effective measure for the treatment of melasma. © 2021 Wiley Periodicals LLC.

Evidence-based practice beliefs and implementations: a cross-sectional study among undergraduate nursing students.

BACKGROUND: Integrating evidence-based practice (EBP) into the daily practice of healthcare professionals has the potential to improve the practice environment as well as patient outcomes. It is essential for nurses to build their body of knowledge, standardize practice, and improve patient outcomes. This study aims to explore nursing students' beliefs and implementations of EBP, to examine the differences in students' beliefs and implementations by prior training of EBP, and to examine the relationship between the same. METHODS: A cross-sectional survey design was used with a convenience sample of 241 nursing students from two public universities. Students were asked to answer the questions in the Evidence-Based Practice Belief and Implementation scales. RESULTS: This study revealed that the students reported a mean total belief score of 54.32 out of 80 (SD = 13.63). However, they reported a much lower implementation score of 25.34 out of 72 (SD = 12.37). Students who received EBP training reported significantly higher total belief and implementation scores than those who did not. Finally, there was no significant relationship between belief and implementation scores (p > .05). CONCLUSION: To advance nursing science, enhance practice for future nurses, and improve patient outcomes, it is critical to teach nursing students not only the value of evidence-based knowledge, but also how to access this knowledge, appraise it, and apply it correctly as needed.

Risk Factors for Complications in Children with Staphylococcus aureus Bacteremia.

OBJECTIVES: To determine risk factors for complications in children with Staphylococcus aureus (S aureus) bacteremia, including methicillin resistance. STUDY DESIGN: Single center, retrospective cohort study of children ≤18 years of age hospitalized with S aureus bacteremia. We compared clinical characteristics and outcomes between those with methicillin-sensitive S aureus (MSSA) and methicillin-resistant S aureus (MRSA) bacteremia. Multivariate regression models identified risk factors associated with developing complications and with longer duration of bacteremia. RESULTS: We identified 394 episodes of S aureus bacteremia, 279 (70.8%) with MSSA, and 115 (29.2%) with MRSA. Primary site of infection was catheter-related in 34%, musculoskeletal in 30%, skin/soft tissue in 10.2%, pneumonia in 6.4%, and endovascular in 6.6%. Eight children (2.0%) died within 30 days because of S aureus bacteremia, 15 (3.5%) had recurrence within 30 days, and 38 (9.6%) had complications including septic emboli or a metastatic focus of infection. Methicillin resistance was associated with development of a complication (aOR 3.31; 95% CI 1.60-6.85), and catheter-related infections were less likely to be associated with a complication (aOR 0.40; 95% CI 0.15-1.03). In a Poisson regression analysis on duration of bacteremia, methicillin resistance, musculoskeletal infection, endovascular infection, black race, and delayed intervention for source control were significantly associated with longer duration of bacteremia. CONCLUSIONS: In this cohort of children with S aureus bacteremia, MRSA infections ere associated with longer duration of bacteremia and a higher likelihood of complications.

Gender equity in planning, development and management of human resources for health: a scoping review.

BACKGROUND: Gender equity remains a challenge across various labor markets with the health market being no exception. Despite the increased influx of women into health professions, horizontal and vertical occupational gender inequities persist. MAIN BODY: The objective of this scoping review is to map the studies on gender equity in healthcare systems in terms of workforce planning, development, and management, as well as to identify the barriers and facilitators for integrating gender equity into healthcare systems. We reviewed the literature on the topic using nine electronic and two grey literature databases with the search strategy combining medical subheadings and keywords for each of the following four concepts of interest: "gender equity," "human resources for health," "healthcare setting," and "management processes." The scoping review included studies focusing on the examination of gender equity at the level of the health workforce. Out of 20,242 studies identified through the database search, the full text of 367 articles was assessed for eligibility and 110 were included in the qualitative analysis. The data of those studies was abstracted and analyzed into themes. Results do not only reveal a global dearth of studies focused on this important topic, but also the concentration of such studies in a few countries around the globe, mainly in North America and Europe. Four out of each five studies included in this review focused on physicians, followed by nurses (14%). In terms of design, an overwhelming majority of studies utilized quantitative designs (75%), followed by qualitative designs and database analyses. Studies were categorized into four pre-determined main themes: facilitators and barriers, workforce planning, HRH management, and HRH development. CONCLUSION: Future research is needed to better understand poorly covered sub-themes such as mentorship, professional development, and training, as well as recruitment and retention among others. It is also equally needed to fill in the gaps in professional groups, study type, methodology, and region. While the review unearthed a number of well-studied themes, significant aspects of the topic remain untapped especially in developing countries and at the level of health professionals other than physicians.

Vitamin D, bone mineral density and risk of fracture in people with intellectual disabilities.

BACKGROUND: People with intellectual disabilities (IDs) have very high rates of osteoporosis and fractures, to which their widespread vitamin D deficiency and other factors could contribute. We aimed to assess in people with IDs previously treated for vitamin D deficiency (1) long-term adherence to vitamin D supplementation and (2) bone mineral density (BMD), as an indicator for risk of fractures, according to vitamin D supplementation and other factors. METHOD: We recorded height, weight, medical, pharmacological, dietary and lifestyle assessment. Blood sample were taken for vitamin D and related analytes. dual-energy X-ray absorptiometry for BMD was performed. RESULTS: Of 51 study participants (mean [standard deviation, SD] age 51.5 [13.6] years, 57% male), 41 (80.4%) were taking vitamin D and 10 were not. Mean [SD] serum vitamin D was 81.3 [21.3] vs. 25.2 [10.2] nmol/L (P < 0.0001), respectively. Thirty-six participants underwent a dual-energy X-ray absorptiometry scan, which showed osteoporosis in 23.7% and osteopenia in 52.6%. Participants on vitamin D had higher BMD than those who were not, a statistically significant difference when confounders (lack of mobility and hypogonadism) were removed. BMD was significantly different according to mobility, particularly in wheelchair users, in whom hip BMD was 33% lower (P < 0.0001) than in participants with normal mobility. Participants still taking vitamin D showed a 6.1% increase in BMD at the spine (P = 0.003) after mean [SD] 7.4 [1.5] years vitamin D treatment. CONCLUSIONS: In people with IDs and previous vitamin D deficiency, BMD increases on long-term vitamin D supplementation. However, additional strategies must be considered for osteoporosis and fracture prevention in this population.

Pediatric Nurses' Perceptions of Their Role in Antimicrobial Stewardship: A Focus Group Study.

PURPOSE: To explore pediatric nurses' perceptions of their role in antimicrobial stewardship. DESIGN AND METHODS: Twelve focus group sessions were conducted at a freestanding children's hospital including 90 nurses across a range of settings, units, and years of experience. Transcripts of the focus group sessions were jointly coded, from which themes were developed. RESULTS: Specific nursing roles in antibiotic stewardship identified include: (1) advocating for the patient, (2) communicating with the team, (3) administering medications safely, (4) educating caregivers, and (5) educating themselves. Identified barriers hindering effective execution of these roles include inconsistent inclusion on rounds and lack of institutional protocols for antibiotic use. CONCLUSION: Nurses easily identified numerous daily nursing tasks that fit within the framework of antimicrobial stewardship and desired additional education and engagement in antibiotic stewardship. IMPLICATIONS: Engaging nurses could improve the structure of antibiotic stewardship programs and break down the barriers that keep nurses from fulfilling their role.

A scoping review of reporting 'Ethical Research Practices' in research conducted among refugees and war-affected populations in the Arab world.

BACKGROUND: Ethical research conduct is a cornerstone of research practice particularly when research participants include vulnerable populations. This study mapped the extent of reporting ethical research practices in studies conducted among refugees and war-affected populations in the Arab World, and assessed variations by time, country of study, and study characteristics. METHODS: An electronic search of eight databases resulted in 5668 unique records published between 2000 and 2013. Scoping review yielded 164 eligible articles for analyses. RESULTS: Ethical research practices, including obtaining institutional approval, access to the community/research site, and informed consent/assent from the research participants, were reported in 48.2, 54.9, and 53.7% of the publications, respectively. Institutional approval was significantly more likely to be reported when the research was biomedical in nature compared to public health and social (91.7% vs. 54.4 and 32.4%), when the study employed quantitative compared to qualitative or mixed methodologies (61.7% vs. 26.8 and 42.9%), and when the journal required a statement on ethical declarations (57.4% vs. 27.1%). Institutional approval was least likely to be reported in papers that were sole-authored (9.5%), when these did not mention a funding source (29.6%), or when published in national journals (0%). Similar results were obtained for access to the community site and for seeking informed consent/assent from study participants. CONCLUSIONS: The responsibility of inadequacies in adherence to ethical research conduct in crisis settings is born by a multitude of stakeholders including funding agencies, institutional research boards, researchers and international relief organizations involved in research, as well as journal editors, all of whom need to play a more proactive role for enhancing the practice of ethical research conduct in conflict settings.

The effect of estradiol on granulosa cell responses to FSH in women with polycystic ovary syndrome.

BACKGROUND: The influence of estradiol (E2) on granulosa cell (GC) function has not been tested clinically in women with polycystic ovary syndrome (PCOS). The objective of this study is to determine if E2 influences GC responses to FSH in women with PCOS. METHODS: This is a two phase, single cohort study conducted over a 2-year period at a single academic center. Nine women with PCOS according to NIH criteria. In Phase 1, FSH stimulation of GC responses as measured by E2 and Inhibin B (Inh B) were assessed before and at 5 and 6 weeks after GnRH agonist administration. In Phase 2, the same protocol was employed with the addition of an aromatase inhibitor (letrozole, LET) administered daily beginning at week 4 for 2 weeks. RESULTS: In Phase 1, recovery of FSH, E2 and Inh B from ovarian suppression occurred at 5 and 6 weeks after GnRH agonist injection and preceded resumption of LH and androgen secretion. In Phase 2, hormone recovery after GnRH agonist was characterized by elevated FSH and suppressed E2 levels whereas recovery of LH and androgen levels were unchanged. In Phase 1, FSH stimulated E2 and Inh B responses were unaltered during recovery from ovarian suppression. In Phase 2, E2 and Inh B fold changes after FSH were significantly reduced at weeks 5 (p < 0.04) and 6 (p < 0.01), respectively. CONCLUSION: In anovulatory women with PCOS, chronic, unopposed E2 secretion may contribute, at least in part, to enhanced ovarian responsiveness to FSH. TRIAL REGISTRATION: NCT02389088.

Health-related information exchange experiences of Jordanian women at breast cancer diagnosis.

The aim of this study was to explore Jordanian women's experiences of information exchange following diagnosis of early stage breast cancer. A purposive sample of 28 women who had surgery for early stage breast cancer within 6 months prior to the interview and had treatment at three hospitals in Central and Northern Jordan was recruited for the study. Data were collected using semi-structured individual interviews focused on women's communication experiences at diagnosis and during cancer treatment. Interviews were audio taped, transcribed verbatim in Arabic, and analyzed using conventional content analysis. Three main themes associated with information exchange were revealed as follows: (1) knowledge about breast cancer and its treatment, (2) communication of cancer diagnosis and treatment, and (3) educating on treatment side effects. Misconceptions about breast cancer risk factors, consequences of breast cancer treatment, and breast cancer-related symptoms were common among participants. Women made important health-related decisions based on misconceptions. Physician's information giving, availability, and responses to women's questions varied by their level of education and the type and location of treatment facility. Informational exchange experiences vary among Jordanian women diagnosed with breast cancer and raise concern over opportunities offered these women to engage in informed decision making. Findings suggest a need for nurses to assess the information needs of Jordanian women newly diagnosed with breast cancer and provide education tailored to individual needs. There is also a need to develop Arabic educational materials and make these available for patients at treatment facilities in all regions of Jordan.

Predictive Value of Methicillin-Resistant Staphylococcus aureus Nasal Swab PCR Assay for MRSA Infection in Critically Ill Pediatric Patients.

BACKGROUND: Critically ill pediatric patients are frequently initiated methicillin-resistant Staphylococcus aureus (MRSA) active antibiotics during infection evaluation even though MRSA infections are rare in many patient populations. The MRSA nasal swab polymerase chain reaction assay (MRSA-NS-PCR) is a test that has been shown to have a high negative predictive value (NPV) for MRSA infection in adults. This study evaluated the diagnostic test characteristics of the MRSA-NS-PCR in predicting the presence of MRSA infection in critically ill pediatric patients. STUDY DESIGN: A retrospective cohort study was performed in a 44-bed pediatric intensive care unit (PICU) between 2013 and 2017. 3860 pediatric patients (54% male, median age 4 years [IQR 1-11 years]) admitted to the PICU who met pediatric systemic inflammatory response syndrome (pSIRS) criteria, were screened with a MRSA-NS-PCR, and had cultures obtained within seven days of MRSA-NS-PCR collection were included. Predictive values and post-test probabilities of the MRSA-NS-PCR for MRSA infection were calculated. RESULTS: MRSA-NS-PCR was positive in 8.6% of patients. MRSA infection was identified in 40 patients, equaling an incidence rate of 2 per 1000 patient days. The MRSA-NS-PCR demonstrated a positive predictive value (PPV) of 9.7%, a NPV of 99.8%, and a post-test probability for a negative test of 0.2% for MRSA infection. CONCLUSIONS: The MRSA-NS-PCR has a poor PPV but a high NPV for MRSA infection in PICU patients when the incidence of MRSA infection is low. Creation of protocols to guide antimicrobial selection based on MRSA-NS-PCR results may lead to improved antimicrobial stewardship and significant risk reduction.
