Interventional Therapies for Pain in Cancer Patients: a Narrative Review.

Curr Pain Headache Rep 2021 May 7;25(7):44. Epub 2021 May 7.

Division of Pain Medicine, Department of Anesthesia, University of Pittsburgh Medical Center, Susquehanna, Williamsport, PA, USA.

Purpose Of Review: Pain is a prevalent symptom in the lives of patients with cancer. In light of the ongoing opioid epidemic and increasing awareness of the potential for opioid abuse and addiction, clinicians are progressively turning to interventional therapies. This article reviews the interventional techniques available to mitigate the debilitating effects that untreated or poorly treated pain have in this population.

Recent Findings: A range of interventional therapies and technical approaches are available for the treatment of cancer-related pain. Many of the techniques described may offer effective analgesia with less systemic toxicity and dependency than first- and second-line oral and parenteral agents. Neuromodulatory techniques including dorsal root ganglion stimulation and peripheral nerve stimulation are increasingly finding roles in the management of oncologic pain. The goal of this pragmatic narrative review is to discuss interventional approaches to cancer-related pain and the potential of such therapies to improve the quality of life of cancer patients.

Respiratory viruses in pediatric emergency department patients and their family members.

Influenza Other Respir Viruses 2021 01 30;15(1):91-98. Epub 2020 Jul 30.

Environmental Health Sciences Department, Mailman School of Public Health, Columbia University, New York, NY, USA.

Background: Respiratory viral infections account for a substantial fraction of pediatric emergency department (ED) visits. We examined the epidemiological patterns of seven common respiratory viruses in children presenting to EDs with influenza-like illness (ILI). Additionally, we examined the co-occurrence of viral infections in the accompanying adults and risk factors associated with the acquisition of these viruses.

Methods: Nasopharyngeal swab were collected from children seeking medical care for ILI and their accompanying adults (Total N = 1315). Study sites included New York Presbyterian, Bellevue, and Tisch hospitals in New York City. PCR using a respiratory viral panel was conducted, and data on symptoms and medical history were collected.

Results: Respiratory viruses were detected in 399 children (62.25%) and 118 (17.5%) accompanying adults. The most frequent pathogen detected was human rhinovirus (HRV) (28.81%). Co-infection rates were 14.79% in children and 8.47% in adults. Respiratory syncytial virus (RSV) and parainfluenza infections occurred more often in younger children. Influenza and HRV occurred more often in older children. Influenza and coronavirus were mostly isolated in winter and spring, RSV in fall and winter and HRV in fall and spring. Children with HRV were more likely to have history of asthma. Adults with the same virus as their child often accompanied ≤ 2-year-old-positive children and were more likely to be symptomatic compared to adults with different viruses.

Conclusions: Respiratory viruses, while presenting the same suite of symptoms, possess distinct seasonal cycles and affect individuals differently based on a number of identifiable factors, including age and history of asthma.

Increased Staphylococcus aureus Nasal Carriage Rates in Rheumatoid Arthritis Patients on Biologic Therapy.

J Arthroplasty 2019 05 17;34(5):954-958. Epub 2019 Jan 17.

Department of Medicine, Hospital for Special Surgery, Weill-Cornell Medical School, New York, NY.

Background: Rheumatoid arthritis patients are at increased risk for periprosthetic joint infection after arthroplasty. The reason is multifactorial. Nasal colonization with Staphylococcus aureus is a modifiable risk factor; carriage rates in RA patients are unknown. The goal of this study is to determine the S aureus nasal carriage rates of RA patients on biologics, RA patients on traditional disease-modifying anti-rheumatic drugs (DMARDs), and osteoarthritis.

Methods: Consecutive patients with RA on biologics (±DMARDs), RA on non-biologic DMARDs, or OA were prospectively enrolled from April 2017 to May 2018. One hundred twenty-three patients were determined necessary per group to show a difference in carriage rates. Patients underwent a nasal swab and answered questions to identify additional risk factors. S aureus positive swabs were further categorized using spa typing. Logistic regression evaluated the association with S aureus colonization between the groups after controlling for known risk factors.

Results: RA patients on biologics, 70% of whom were on DMARDs, had statistically significant increase in S aureus colonization (37%) compared to RA on DMARDs alone (24%), or OA (20%) (P = .01 overall). After controlling for glucocorticoids, antibiotic use, recent hospitalization, and diabetes, RA on biologics had a significant increased risk of S aureus nasal colonization (Odds ratio 1.80, 95% confidence interval 1.00-3.22, P = .047).

Conclusion: S aureus colonization risk was increased for RA on biologics compared to RA not on biologics and OA. Nasal S aureus carriage increases the risk of surgical site infection; this modifiable risk factor should be addressed prior to total joint arthroplasty for this higher risk patient group.

Comparison of the Single-Syringe Push-Pull Technique With the Discard Technique for Obtaining Blood Samples From Pediatric Central Venous Access Devices.

J Pediatr Oncol Nurs 2017 Nov/Dec;34(6):381-386. Epub 2017 Jul 6.

3 St Joseph's Hospital, Marshfield, WI, USA.

The discard technique is the most widely used method of obtaining blood samples from patients with central venous access devices (CVADs), but risks removing more blood than is necessary for laboratory testing and may increase a patient's risk of anemia. We hypothesized that laboratory results from pediatric blood specimens obtained via CVAD using the single-syringe push-pull (formerly called the mixing) method and the discard method would be similar. Blood samples were obtained from pediatric oncology patients in a hospital setting using both collection methods and laboratory values were analyzed for concordance using the pairwise t-test, intraclass correlation coefficient, and Bland-Altman analysis methods. Statistical analysis revealed significant differences for sodium, potassium, chloride, bicarbonate, creatinine, calcium, white blood cell count, hemoglobin, hematocrit, and platelet count, but these differences were not clinically significant and within the standard error of measurement for the instrument. Given the similarity in laboratory results, the push-pull method should be considered for obtaining blood samples from CVADs in pediatric patients to avoid unnecessary blood loss.

Reconstructing source-sink dynamics in a population with a pelagic dispersal phase.

PLoS One 2014 16;9(5):e95316. Epub 2014 May 16.

For many organisms, the reconstruction of source-sink dynamics is hampered by limited knowledge of the spatial assemblage of either the source or sink components or lack of information on the strength of the linkage for any source-sink pair. In the case of marine species with a pelagic dispersal phase, these problems may be mitigated through the use of particle drift simulations based on an ocean circulation model. However, when simulated particle trajectories do not intersect sampling sites, the corroboration of model drift simulations with field data is hampered. Here, we apply a new statistical approach for reconstructing source-sink dynamics that overcomes the aforementioned problems. Our research is motivated by the need for understanding observed changes in jellyfish distributions in the eastern Bering Sea since 1990. By contrasting the source-sink dynamics reconstructed with data from the pre-1990 period with that from the post-1990 period, it appears that changes in jellyfish distribution resulted from the combined effects of higher jellyfish productivity and longer dispersal of jellyfish resulting from a shift in the ocean circulation starting in 1991. A sensitivity analysis suggests that the source-sink reconstruction is robust to typical systematic and random errors in the ocean circulation model driving the particle drift simulations. The jellyfish analysis illustrates that new insights can be gained by studying structural changes in source-sink dynamics. The proposed approach is applicable for the spatial source-sink reconstruction of other species and even abiotic processes, such as sediment transport.

Recurrent jellyfish blooms are a consequence of global oscillations.

Proc Natl Acad Sci U S A 2013 Jan 31;110(3):1000-5. Epub 2012 Dec 31.

A perceived recent increase in global jellyfish abundance has been portrayed as a symptom of degraded oceans. This perception is based primarily on a few case studies and anecdotal evidence, but a formal analysis of global temporal trends in jellyfish populations has been missing. Here, we analyze all available long-term datasets on changes in jellyfish abundance across multiple coastal stations, using linear and logistic mixed models and effect-size analysis to show that there is no robust evidence for a global increase in jellyfish. Although there has been a small linear increase in jellyfish since the 1970s, this trend was unsubstantiated by effect-size analysis that showed no difference in the proportion of increasing vs. decreasing jellyfish populations over all time periods examined. Rather, the strongest nonrandom trend indicated jellyfish populations undergo larger, worldwide oscillations with an approximate 20-y periodicity, including a rising phase during the 1990s that contributed to the perception of a global increase in jellyfish abundance. Sustained monitoring is required over the next decade to elucidate with statistical confidence whether the weak increasing linear trend in jellyfish after 1970 is an actual shift in the baseline or part of an oscillation. Irrespective of the nature of increase, given the potential damage posed by jellyfish blooms to fisheries, tourism, and other human industries, our findings foretell recurrent phases of rise and fall in jellyfish populations that society should be prepared to face.
