Reduced Pain and Improved Function Following Short-Term Use of Noninvasive BioWave High Frequency Peripheral Nerve Stimulation for Pain Management.

INTRODUCTION: The peripheral nervous system is an increasingly popular target for chronic pain treatment modalities. Noninvasive neuromodulation has shown promise at providing significant chronic pain relief with a much safer side effect profile. This retrospective pilot study is shaped around a noninvasive neuromodulation system over a 2-week treatment timeline. METHODS: Open-label survey of chronic pain patients recruited from Veteran Affairs, orthopedic, and pain health systems. If a noninvasive neuromodulation system was prescribed the patients were then offered a 2-week follow-up survey. This voluntary survey did not affect their therapy duration or quality. This survey was designed to address similar metrics as smaller noninvasive neuromodulation studies to allow a quality comparison while giving more power with a large population size of 1511 patients. Overall pain scores (including before and after scores), satisfaction level, desire to continue therapy, medication use, effect on functional metrics (mood, sleep, sit, stand, walk, and lift), and activities of daily living (ADL) scores were assessed. RESULTS: The results demonstrated an overall pain reduction of 46%. All functional metrics were improved throughout with the largest improvements reported in mood and sleep at over 47%. Medication use was reported as decreased or eliminated in 42% of patients. There were no adverse reactions or complications reported over the 1511 patients. CONCLUSION: This survey is amongst the largest population sizes every studied for noninvasive neuromodulation. Within just 2 weeks patients can see a reduction in overall pain and medication needs. Although survey studies have inherent limitations such as duration and compliance biases with such an overwhelming benefit in every category we believe that noninvasive neuromodulation therapy is a promising, safe, and cost-effective therapy. Future studies should focus on long-term follow-ups and post-therapy pain scores with a placebo group.

Dialysis symptom index burden and symptom clusters in a prospective cohort of dialysis patients.

BACKGROUND: Dialysis patients experience a high symptom burden, which may adversely impact their quality of life. Whereas other specialties emphasize routine symptom assessment, symptom burden is not well-characterized in dialysis patients. We sought to examine the prevalence and severity of unpleasant symptoms in a prospective hemodialysis cohort. METHODS: Among 122 hemodialysis patients from the prospective Malnutrition, Diet, and Racial Disparities in Chronic Kidney Disease (CKD) study, CKD-associated symptoms were ascertained by the Dialysis Symptom Index, a validated survey assessing symptom burden/severity (with higher scores indicating greater symptom severity), over 6/2020-10/2020. We examined the presence of (1) individual symptoms and symptom severity scores, and (2) symptom clusters (defined as ≥ 2 related concurrent symptoms), as well as correlations with clinical characteristics. RESULTS: Symptom severity scores were higher among non-Hispanic White and Hispanic patients, whereas scores were lower in Black and Asian/Pacific Islander patients. In the overall cohort, the most common individual symptoms included feeling tired/lack of energy (71.3%), dry skin (61.5%), trouble falling asleep (44.3%), muscle cramps (42.6%), and itching (42.6%), with similar patterns observed across racial/ethnic groups. The most prevalent symptom clusters included feeling tired/lack of energy + trouble falling asleep (37.7%); trouble falling asleep + trouble staying asleep (34.4%); and feeling tired/lack of energy + trouble staying asleep (32.0%). Lower hemoglobin, iron stores, and dialysis adequacy correlated with higher individual and overall symptom severity scores. CONCLUSION: We observed a high prevalence of unpleasant symptoms and symptom clusters in a diverse hemodialysis cohort. Further studies are needed to identify targeted therapies that ameliorate symptom burden in CKD.

Nanotechnology and Health.

: Potential adverse health effects associated with exposure to engineered or synthesized nanomaterials have not been reported in humans; however, there is accumulating evidence from animal studies that exposure to some nanomaterials is harmful. While there is uncertainty as to the likelihood, frequency, and intensity of exposures experienced by those working around engineered nanoparticles, the American College of Occupational and Environmental Medicine has developed this guidance document for occupational medicine physicians and their colleagues to offer prudent preventive recommendations on the topics of exposure monitoring, exposure controls, and medical surveillance.

Characteristics of emergency department patients who receive a palliative care consultation.

BACKGROUND: A large gap exists between the practice of emergency medicine and palliative care. Although hospice and palliative medicine has recently been recognized as a subspecialty of emergency medicine, few palliative care teams routinely interact with emergency providers, and primary palliative care skills among emergency providers are lacking. OBJECTIVE: To identify the proportion and characteristics of patients who receive a palliative care consultation and arrive via the emergency department (ED). METHODS: A descriptive study of adult ED patients from an urban, academic tertiary care hospital who received a palliative care consultation in January 2005 or January 2009. RESULTS: In January 2005, 100 of the 161 consults (62%) arrived via the ED versus 63 of 124 consults (51%) in January 2009 (p=0.06). Mean days from admission to consultation in January 2005 were six days (standard deviation 11), versus nine days (SD 26) in January 2009 (p=0.35). Three of the 100 consultations (3%) in January 2005 were initiated in the ED, versus 4 of the 64 (6%) in January 2009. CONCLUSIONS: At an urban academic medical center with a well-developed palliative care service, the majority of palliative care consultations were for patients who arrive via the ED. Despite this, only a small minority of consultations originated from emergency providers and consultation was on average initiated days into a patient's hospital stay.

National Institute for Occupational Safety and Health Nanomaterials and Worker Health Conference--medical surveillance session summary report.

OBJECTIVES: The goal of these sessions was to identify current practices and recommendations regarding medical surveillance for nanomaterial workers. METHODS: Conference participants met in three discussion groups. RESULTS: There were few existing programs directed to nanomaterial workers. Participants expressed a range of views, from feeling that comprehensive medical surveillance is important currently to suggesting that targeted medical surveillance will become important when more complete data are available to assess risks. CONCLUSIONS: Results of health outcomes research for ultrafine air pollution and toxicological information about specific nanomaterials should inform the design of medical surveillance programs. Groups with high exposures should be identified and targeted. Overall, because of uncertainties in the health effects of concern, investments in control measures, exposure assessment efforts, and exposure registries are currently most likely to be important prevention strategies.
