Feasibility of a comprehensive medication review to improve medication use for patients with cancer and comorbid conditions.

PURPOSE: A focus on oral medications for patients receiving care from both oncologists and primary care providers elicits an opportunity for improvement in patient outcomes. The purpose of this pilot study was to explore the feasibility and appropriateness of a comprehensive medication review (CMR) by a primary care pharmacist in a population of patients with cancer and chronic conditions. METHODS: Adult patients who received both cancer and primary care at Michigan Medicine, received active systemic cancer treatment, and had a comorbid condition of diabetes, hypertension, chronic heart failure, depression, and/or anxiety were eligible to receive a CMR by the primary care clinical pharmacist. Data collected included number eligible for the CMR (feasibility), patient demographics, medication-related problems (MRPs) and medication interventions (appropriate), number of patients requiring follow-up with the clinical pharmacist or physician, and pre/post-intervention changes in A1c and BP, as applicable. RESULTS: Of the 96 patients that met inclusion criteria, 55 patients (57%) received a CMR. Pharmacists provided 66 instances of patient education and identified 22 medication-related problems (MRPs) in 15 (27%) of patients. After CMRs were completed, 22 patients (40%) were referred to primary care pharmacists or physician providers for ongoing care. CONCLUSION: A CMR was feasible and appropriate for patients with chronic conditions receiving treatment for cancer.

The efficacy of cognitive behavioral therapy for mental health and quality of life among individuals diagnosed with cancer: A systematic review and meta-analysis.

OBJECTIVE: It has long been documented that cognitive behavioral therapy (CBT) has positive impacts on improving mental health (MH) and quality of life (QoL) in the general population, but investigations on its effect on cancer survivors remain limited, especially for QoL outcomes. The purpose of this meta-analysis is to investigate the effects of CBT as compared to control on cancer patients' MH and QoL outcomes. Control is defined in this study as standard therapy, waitlist control, and active/alternative therapy. METHODS: In total, 154 clinical trials creating a sample size of 1627 individuals were collected. Analysis focusing on MH and QoL excluded 29 clinical trials resulting in a final analysis of 132 clinical trials (and 1030 effect sizes). R Statistical Software (version 4.2.2) and the robumeta package were utilized to complete analysis, which entailed robust variance estimation (RVE) in intercept-only meta-regression, and univariate meta-regression (for moderator analysis). RESULTS: Across 132 clinical trials and 1030 effect size estimates, we identified that CBT moderately improves MH and QoL in cancer patients d = 0.388, 95% CI 0.294-0.483, p < 0.001. Additionally, age and delivery format can influence the efficacy of CBT in this patient population. CONCLUSIONS: CBT statistically improves the MH and QoL psychosocial parameters in cancer patients with greater efficacy in younger patients. Important clinical and intervention-related factors, that is, age and delivery, should be considered when oncologists consider CBT as a psychotherapeutic intervention for individuals with cancer.

Concomitant Listeria monocytogenes and Streptococcus equinus brain abscess in an immunocompetent individual: a case report.

BACKGROUND: Listeria monocytogenes brain abscess is a rare phenomenon that is common in immunocompromised patients. Streptococcus equinus brain abscess has never been reported in the literature to our knowledge. In this case report, we describe a case of brain abscess secondary to Listeria monocytogenes and Streptococcus equinus in an immunocompetent patient with transient low CD4 count. CASE PRESENTATION: A 27-year-old white, male patient, previously healthy, nonalcoholic, and occasional smoker, presented to the emergency department for confusion and headache. The patient was found to have a left parietal abscess, which was drained and the fluid was sent for culture. Culture grew Listeria monocytogenes and Streptococcus equinus. The patient was treated with intravenous ampicillin followed by oral amoxicillin for a total of 6 weeks. The CD4 count was low initially. However, after the resolution of the infection, the CD4 count came back within normal range. Another brain magnetic resonance imaging was done that showed a significantly decreased hyperintensity within the left parietal subcortical white matter at the site of surgery with significantly decreased enhancement and almost total resolution of the previous abscess. CONCLUSION: Transient low CD4 count is a rare phenomenon that exposes patients to unusual and atypical infections. Since low CD4 count is transient, patients treated promptly recover from their illness. Our patient developed a Listeria monocytogenes and Streptococcus equinus brain abscess, which is considered rare and has not been previously described in the literature to our knowledge.

Cystic fibrosis airway microbiota associated with outcomes of nontuberculous mycobacterial infection.

RATIONALE: Pulmonary infections with nontuberculous mycobacteria (NTM) are increasingly prevalent in people with cystic fibrosis (CF). Clinical outcomes following NTM acquisition are highly variable, ranging from transient self-resolving infection to NTM pulmonary disease associated with significant morbidity. Relationships between airway microbiota and variability of NTM outcomes in CF are unclear. OBJECTIVE: To identify features of CF airway microbiota associated with outcomes of NTM infection. METHODS: 188 sputum samples, obtained from 24 subjects with CF, each with three or more samples collected from 3.5 years prior to, and up to 6 months following incident NTM infection, were selected from a sample repository. Sputum DNA underwent bacterial 16S rRNA gene sequencing. Airway microbiota were compared based on the primary outcome, a diagnosis of NTM pulmonary disease, using Wilcoxon rank-sum testing, autoregressive integrated moving average modelling and network analyses. MEASUREMENTS AND MAIN RESULTS: Subjects with and without NTM pulmonary disease were similar in clinical characteristics, including age and lung function at the time of incident NTM infection. Time-series analyses of sputum samples prior to incident NTM infection identified positive correlations between Pseudomonas, Streptococcus, Veillonella, Prevotella and Rothia with diagnosis of NTM pulmonary disease and with persistent NTM infection. Network analyses identified differences in clustering of taxa between subjects with and without NTM pulmonary disease, and between subjects with persistent versus transient NTM infection. CONCLUSIONS: CF airway microbiota prior to incident NTM infection are associated with subsequent outcomes, including diagnosis of NTM pulmonary disease, and persistence of NTM infection. Associations between airway microbiota and NTM outcomes represent targets for validation as predictive markers and for future therapies.

Comparative Genomics of Mycobacterium avium Complex Reveals Signatures of Environment-Specific Adaptation and Community Acquisition.

Nontuberculous mycobacteria, including those in the Mycobacterium avium complex (MAC), constitute an increasingly urgent threat to global public health. Ubiquitous in soil and water worldwide, MAC members cause a diverse array of infections in humans and animals that are often multidrug resistant, intractable, and deadly. MAC lung disease is of particular concern and is now more prevalent than tuberculosis in many countries, including the United States. Although the clinical importance of these microorganisms continues to expand, our understanding of their genomic diversity is limited, hampering basic and translational studies alike. Here, we leveraged a unique collection of genomes to characterize MAC population structure, gene content, and within-host strain dynamics in unprecedented detail. We found that different MAC species encode distinct suites of biomedically relevant genes, including antibiotic resistance genes and virulence factors, which may influence their distinct clinical manifestations. We observed that M. avium isolates from different sources-human pulmonary infections, human disseminated infections, animals, and natural environments-are readily distinguished by their core and accessory genomes, by their patterns of horizontal gene transfer, and by numerous specific genes, including virulence factors. We identified highly similar MAC strains from distinct patients within and across two geographically distinct clinical cohorts, providing important insights into the reservoirs which seed community acquisition. We also discovered a novel MAC genomospecies in one of these cohorts. Collectively, our results provide key genomic context for these emerging pathogens and will facilitate future exploration of MAC ecology, evolution, and pathogenesis. IMPORTANCE Members of the Mycobacterium avium complex (MAC), a group of mycobacteria encompassing M. avium and its closest relatives, are omnipresent in natural environments and emerging pathogens of humans and animals. MAC infections are difficult to treat, sometimes fatal, and increasingly common. Here, we used comparative genomics to illuminate key aspects of MAC biology. We found that different MAC species and M. avium isolates from different sources encode distinct suites of clinically relevant genes, including those for virulence and antibiotic resistance. We identified highly similar MAC strains in patients from different states and decades, suggesting community acquisition from dispersed and stable reservoirs, and we discovered a novel MAC species. Our work provides valuable insight into the genomic features underlying these versatile pathogens.

The deacylase SIRT5 supports melanoma viability by influencing chromatin dynamics.

Cutaneous melanoma remains the most lethal skin cancer, and ranks third among all malignancies in terms of years of life lost. Despite the advent of immune checkpoint and targeted therapies, only roughly half of patients with advanced melanoma achieve a durable remission. Sirtuin 5 (SIRT5) is a member of the sirtuin family of protein deacylases that regulates metabolism and other biological processes. Germline Sirt5 deficiency is associated with mild phenotypes in mice. Here we showed that SIRT5 was required for proliferation and survival across all cutaneous melanoma genotypes tested, as well as uveal melanoma, a genetically distinct melanoma subtype that arises in the eye and is incurable once metastatic. Likewise, SIRT5 was required for efficient tumor formation by melanoma xenografts and in an autochthonous mouse Braf Pten-driven melanoma model. Via metabolite and transcriptomic analyses, we found that SIRT5 was required to maintain histone acetylation and methylation levels in melanoma cells, thereby promoting proper gene expression. SIRT5-dependent genes notably included MITF, a key lineage-specific survival oncogene in melanoma, and the c-MYC proto-oncogene. SIRT5 may represent a druggable genotype-independent addiction in melanoma.

Distribution and outcomes of infection of Mycobacterium avium complex species in cystic fibrosis.

BACKGROUND: The majority of nontuberculous mycobacterial (NTM) pulmonary infections in people with cystic fibrosis (CF) are caused by Mycobacterium avium complex (MAC) species. Data on MAC species distribution and outcomes of infection in CF are lacking. METHODS: This was a single center, retrospective study. MAC isolates had species identification with MLSA of rpoB and the 16S23S ITS region. Clinical data were compared between species. RESULTS: Twenty-three people with CF and 57 MAC isolates were included. Infection with M. avium was the most common (65.2%). M. intracellulare was associated with higher rates of NTM disease, younger age, and steeper decline in lung function prior to infection. CONCLUSIONS: We observed worse clinical outcomes in people with M. intracellulare infection relative to other MAC species. Further investigation of clinical outcomes of MAC infection among CF patients is warranted to better define the utility of species-level identification of MAC isolates in CF.

Measures of Cystic Fibrosis Airway Microbiota during Periods of Clinical Stability.

Rationale: Differences in cystic fibrosis (CF) airway microbiota between periods of clinical stability and exacerbation of respiratory symptoms have been investigated in efforts to better understand microbial triggers of CF exacerbations. Prior studies have often relied on a single sample or a limited number of samples to represent airway microbiota. However, the variability in airway microbiota during periods of clinical stability is not well known.Objectives: To determine the temporal variability of measures of airway microbiota during periods of clinical stability, and to identify factors associated with this variability.Methods: Sputum samples (N = 527), obtained daily from six adults with CF during 10 periods of clinical stability, underwent sequencing of the V4 region of the bacterial 16S ribosomal RNA gene. The variability in airway microbiota among samples within each period of clinical stability was calculated as the average of the Bray-Curtis similarity measures of each sample to every other sample within the same period. Outlier samples were defined as samples outside 1.5 times the interquartile range within a baseline period with respect to the average Bray-Curtis similarity. Total bacterial load was measured with droplet digital polymerase chain reaction.Results: The variation in Bray-Curtis similarity and total bacterial load among samples within the same baseline period was greater than the variation observed in technical replicate control samples. Overall, 6% of samples were identified as outliers. Within baseline periods, changes in bacterial community structure occurred coincident with changes in maintenance antibiotics (P < 0.05, analysis of molecular variance). Within subjects, bacterial community structure changed between baseline periods (P < 0.01, analysis of molecular variance). Sample-to-sample similarity within baseline periods was greater with fewer interval days between sampling.Conclusions: During periods of clinical stability, airway bacterial community structure and bacterial load vary among daily sputum samples from adults with CF. This day-to-day variation has bearing on study design and interpretation of results, particularly in analyses that rely on single samples to represent periods of interest (e.g., clinical stability vs. pulmonary exacerbation). These data also emphasize the importance of accounting for maintenance antibiotic use and granularity of sample collection in studies designed to assess the dynamics of CF airway microbiota relative to changes in clinical state.

Review of Community Based Organization and Community Pharmacy Partnerships for Preventive Care Services.

Collaborative care has been widely recognized as being critical to promoting the health of individuals and populations. It is hypothesized that the development of partnerships between community-based organizations and community pharmacies may result in increased access to preventive care services for community members with the goal of improving health outcomes. The purpose of this review was to identify and describe partnerships between community-based organizations and community pharmacies. A literature search was conducted for all articles in the English language published through January 2018 that included these types of partnerships offering preventive care services. A total of seven articles were included in the review, of which the majority were conducted in the United States (n=5). Community-based organizations included businesses, community health centers, local associations, public health departments, schools, and workplaces. Preventive care services that were offered included blood pressure and cardiovascular risk assessment, diabetes management, flu ready card and HIV self-test kit voucher distribution and education, and bone mineral density screenings. The limited literature suggests that additional opportunities should be explored in order for community-based organizations and community pharmacies to partner in order to provide and evaluate the impact of preventive care services in the community setting.
