Spillover adherence effects of fixed-dose combination HIV therapy

The impact of fixed-dose combination (FDC) products on adherence to other, non-fixed regimen components has not been examined. We compared adherence to a third antiretroviral (ART) component among patients receiving a nucleoside reverse transcriptase inhibitor (NRTI) backbone consisting of the FDC Epzicom®, GlaxoSmithKline Inc, Research Triangle Park, NC (abacavir sulfate 600 mg + lamivudine 300 mg; FDC group) versus NRTI combinations taken as two separate pills (NRTI Combo group) using data from a national sample of 30 health plans covering approximately 38 million lives from 1997 to 2005. Adherence was measured as the medication possession ratio (MPR). Multivariate logistic regression compared treatment groups based on the likelihood of achieving ≥95% adherence, with sensitivity analyses using alternative thresholds. MPR was assessed as a continuous variable using multivariate linear regression. Covariates included age, gender, insurance payer type, year of study drug initiation, presence of mental health and substance abuse disorders, and third agent class. The study sample consisted of 650 FDC and 1947 NRTI Combo patients. Unadjusted mean adherence to the third agent was higher in the FDC group than the NRTI Combo group (0.92 vs 0.85; P < 0.0001). In regression analyses, FDC patients were 48% and 39% more likely to achieve 95% and 90% third agent adherence, respectively (P ≤ 0.03). None of the other MPR specifications achieved comparable results. Among managed care patients, use of an FDC appears to substantially improve adherence to a third regimen component and thus the likelihood of achieving the accepted standard for adherence to HIV therapy of 95%

Advising Black Students and Anti-Oppressive Frameworks: A Systematic Review of College Access and College Counseling Literature

It is well known that Black students have higher expectations for attending college than their White and non-White peers, yet consistently lag behind in degree attainment. It is important then that practitioners use differentiated approaches with and researchers offer disaggregated analyses of historically underrepresented racial/ethnic minoritized populations in the college advising process. Doing so could reveal systemic barriers to achievement and advancement that are specific, in this instance, to Black students. Since the role and practice of college advising is (or at least should be) informed by the extant literature, then a systematic review is an ideal avenue for scholarly inquiry, paying particular attention to how prior literature utilized anti-oppressive frameworks. This method allowed us to map current knowledge and strategies, as well as identify conceptual, methodological, and interpretive gaps in the current literature. Across our analysis, our findings reveal there is more work to be done, particularly focusing on representation, disaggregation, and application

Breathing easier: Addressing the challenges of aerosolizing medications to infants and preschoolers

An increasing number of patients are dependent on aerosolized therapy to manage pulmonary diseases, including asthma, cystic fibrosis, and pulmonary arterial hypertension. An aerosol therapy is only useful if it can be appropriately and consistently delivered in the desired dose to the lower respiratory tract. Many factors affect this deposition in young children, including anatomical and physiologic differences between adults and children, patient-mask interface issues, the challenge of administering medication to uncooperative children, and behavioral adherence. Moreover, the techniques used to assess aerosol delivery to pediatric patients need to be carefully evaluated as new therapies and drug-device combinations are tested. In this review, we will address some of the challenges of delivering aerosolized medications to pediatric patients

Early respiratory viral infections in infants with cystic fibrosis

This article is made available for unrestricted research re-use and secondary analysis in any form or by any means with acknowledgement of the original source. These permissions are granted for the duration of the World Health Organization (WHO) declaration of COVID-19 as a global pandemic.Background Viral infections contribute to morbidity in cystic fibrosis (CF), but the impact of respiratory viruses on the development of airway disease is poorly understood. Methods Infants with CF identified by newborn screening were enrolled prior to 4 months of age to participate in a prospective observational study at 4 centers. Clinical data were collected at clinic visits and weekly phone calls. Multiplex PCR assays were performed on nasopharyngeal swabs to detect respiratory viruses during routine visits and when symptomatic. Participants underwent bronchoscopy with bronchoalveolar lavage (BAL) and a subset underwent pulmonary function testing. We present findings through 8.5 months of life. Results Seventy infants were enrolled, mean age 3.1 ± 0.8 months. Rhinovirus was the most prevalent virus (66%), followed by parainfluenza (19%), and coronavirus (16%). Participants had a median of 1.5 viral positive swabs (range 0–10). Past viral infection was associated with elevated neutrophil concentrations and bacterial isolates in BAL fluid, including recovery of classic CF bacterial pathogens. When antibiotics were prescribed for respiratory-related indications, viruses were identified in 52% of those instances. Conclusions Early viral infections were associated with greater neutrophilic inflammation and bacterial pathogens. Early viral infections appear to contribute to initiation of lower airway inflammation in infants with CF. Antibiotics were commonly prescribed in the setting of a viral infection. Future investigations examining longitudinal relationships between viral infections, airway microbiome, and antibiotic use will allow us to elucidate the interplay between these factors in young children with CF

A Survey of Campus Coordinators of Undergraduate Research Programs

Interest in supporting undergraduate research programs continues to grow within academic librarianship. This article presents how undergraduate research program coordinators perceive and value library support of their programs.

This article seeks to present a critical perspective on library support for undergraduate research programs from an important external constituent group of faculty and administrators. The data and recommendations can further conversations and aid collaboration between librarians and their campus colleagues.Ope

Bacterial Thymidine Kinase as a Non-Invasive Imaging Reporter for Mycobacterium tuberculosis in Live Animals

Bacteria can be selectively imaged in experimentally-infected animals using exogenously administered 1-(2'deoxy-2'-fluoro-beta-D-arabinofuranosyl)-5-[(125)I]-iodouracil ([(125)I]-FIAU), a nucleoside analog substrate for bacterial thymidine kinase (TK). Our goal was to use this reporter and develop non-invasive methods to detect and localize Mycobacterium tuberculosis.We engineered a M. tuberculosis strain with chromosomally integrated bacterial TK under the control of hsp60 -- a strong constitutive mycobacterial promoter. [(125)I]FIAU uptake, antimicrobial susceptibilities and in vivo growth characteristics were evaluated for this strain. Using single photon emission computed tomography (SPECT), M. tuberculosis P(hsp60) TK strain was evaluated in experimentally-infected BALB/c and C3HeB/FeJ mice using the thigh inoculation or low-dose aerosol infection models. M. tuberculosis P(hsp60) TK strain actively accumulated [(125)I]FIAU in vitro. Growth characteristics of the TK strain and susceptibility to common anti-tuberculous drugs were similar to the wild-type parent strain. M. tuberculosis P(hsp60) TK strain was stable in vivo and SPECT imaging could detect and localize this strain in both animal models tested.We have developed a novel tool for non-invasive assessment of M. tuberculosis in live experimentally-infected animals. This tool will allow real-time pathogenesis studies in animal models of TB and has the potential to simplify preclinical studies and accelerate TB research

In children, the microbiota of the nasopharynx and bronchoalveolar lavage fluid are both similar and different

RATIONALE: Sputum and bronchoalveolar lavage fluid (BALF) are often obtained to elucidate the lower airway microbiota in adults. Acquiring sputum samples from children is difficult and obtaining samples via bronchoscopy in children proves challenging due to the need for anesthesia and specialized procedural expertise; therefore nasopharyngeal (NP) swabs are often used as surrogates when investigating the pediatric airway microbiota. In adults, the airway microbiota differs significantly between NP and BALF samples however, minimal data exist in children. OBJECTIVES: To compare NP and BALF samples in children undergoing clinically indicated bronchoscopy. METHODS: NP and BALF samples were collected during clinically indicated bronchoscopy. Bacterial DNA was extracted from 72 samples (36 NP/BALF pairs); the bacterial V1-V3 region of the 16S rRNA gene was amplified and sequenced on the Illumina Miseq platform. Analysis was performed using mothur software. RESULTS: Compared to NP samples, BALF had increased richness and diversity. Similarity between paired NP and BALF (intra-subject) samples was greater than inter-subject samples (P = 0.0006). NP samples contained more Actinobacteria (2.2% vs 21%; adjusted P = 1.4 × 10-6 ), while BALF contained more Bacteroidetes (29.5% vs 3.2%; adjusted P = 1.2 × 10-9 ). At the genus level several differences existed, however Streptococcus abundance was similar in both sample types (NP 37.3% vs BAL 36.1%; adjusted P = 0.8). CONCLUSION: Our results provide evidence that NP samples can be used to distinguish differences between children, but the relative abundance of organisms may differ between the nasopharynx and lower airway in pediatric patients. Studies utilizing NP samples as surrogates for the lower airway should be interpreted with caution

Protocol for the RELATE trial:A feasibility and pilot randomised controlled trial of a low-intensity group intervention for young people in care with elevated posttraumatic stress symptoms

Introduction: Young people in out-of-home care have often experienced trauma, such as direct maltreatment or witnessing violence. There is good evidence that rates of mental health difficulties are high in this group, including posttraumatic stress disorder (PTSD), a trauma-specific mental health outcome. There remains less evidence to guide how to effectively address elevated PTSD symptoms (PTSS) in these young people, particularly in ways that are feasible and scalable for stretched social-care and mental health services. Methods and analysis: This protocol describes a feasibility study comprising a pilot two-arm randomised controlled trial (RCT). Participants (N = 50) will be randomised to either (a) a group-based trauma-focused programme (Teaching Recovery Techniques), delivered by mental health practitioners both online and in-person, or (b) care-as-usual. Primarily, the trial aims to explore the key feasibility and protocol acceptability questions, including rates of recruitment and retention, as well as the acceptability of the intervention (particularly the online delivery format) to participants and services. In addition, outcomes including PTSS (primary clinical outcome), depression and functioning will be assessed at baseline (pre-randomisation), post-intervention and at a 3-month follow-up. Ethics and dissemination: Ethical approval has been received from the Health Research Authority (Wales REC1 Ref 20/WA/0100) and University, with further approval from the host trust and social care site. The results will inform the design of a definitive RCT. Dissemination will include peer-reviewed journal articles reporting the qualitative and quantitative results, as well as presentations at conferences and lay summaries.
