A population analysis of delayed ejaculation using a claims database: characteristics and national trends in prevalence, incidence, and pharmacotherapy.

We investigated the prevalence, incidence, and rates of pharmacological treatment of delayed ejaculation using the TriNetX Diamond Network. We included all men evaluated in the inpatient, outpatient, and emergency settings. Prevalence was determined by comparing the number of men diagnosed with delayed ejaculation to the entire population. Incidence was determined by comparing the number of men diagnosed with delayed ejaculation without a prior diagnosis to the overall population without a prior diagnosis. Rates of pharmacologic treatment were calculated by comparing the number of men who received a prescription to the total number of men with delayed ejaculation. Trends in prevalence and incidence were compared using six-month intervals, while trends in pharmacologic treatment were compared using one-year intervals. A total of 23,164 adult males were diagnosed with delayed ejaculation from 2013 to 2019. During the final six-month interval (July to December 2019), 2,747 of 16,496,744 men received a delayed ejaculation diagnosis, and 1,375 of 16,488,270 men without a prior diagnosis were diagnosed with delayed ejaculation. In 2019, only 916 of 4,733 (19.4%) men diagnosed with delayed ejaculation received any prescription, with the most common being testosterone (9.5%), bupropion (6.6%), and buspirone (2.3%). Prevalence, incidence and pharmacologic treatment all had increasing trends.

Chronic Use of Prescription Pain Medication and Outcomes in Patients with Burn Injury: A Burn Model System National Database Study.

OBJECTIVE: This study attempts to examine long-term pain medication usage after burn injury and its association with functional and psychosocial outcomes. DESIGN: This is a multi-center retrospective cohort study utilizing the Burn Model System National Longitudinal Database. Participants injured from 2015 to 2021 were divided into two groups, those taking and not taking prescription pain medication at 12 months after injury. Regression analyses examined associations between pain medication use and outcomes at 12 months, adjusting for demographics, burn size, length of hospital stay, and pre-injury pain medication use and employment status. Outcomes included VR-12 Physical and Mental Component Summary scores (PCS and MCS), Patient-Reported Outcomes Measurement Information System (PROMIS-29) Anxiety and Depression scores, Satisfaction with Life Scale (SWLS), and employment status. RESULTS: Of 358 participants analyzed, prescription pain medication use was associated with worse outcomes at 12 months: PCS (ß = -7.11, p < 0.001), MCS (ß = -6.01, p < 0.001), and PROMIS-29 Depression (ß = 4.88, p < 0.001) and Anxiety (ß = 6.16, p < 0.001). SWLS was not significantly associated with pain medication use (p = 0.069) and those taking pain medication were 52% less likely to be employed at 12 months (p = 0.035). CONCLUSION: There is a significant association between prescription pain medication use and worse physical, mental, and employment outcomes at 12 months after burn injury.

Patient-reported outcomes during telehealth versus in-person follow-up visits for patients treated with extracorporeal shockwave therapy.

BACKGROUND: The limited research describing clinical outcomes using telehealth for management of musculoskeletal conditions is primarily within orthopedic surgery care. OBJECTIVE: To characterize differences in patient reported outcomes using telehealth compared with in-person follow-up visits in patients with Achilles tendinopathy (AT) or plantar fasciitis (PF) treated using extracorporeal shockwave therapy (ESWT). DESIGN: Retrospective chart review. SETTING: Outpatient sports medicine clinic. PATIENTS: 82 patients with AT and 46 patients with PF. INTERVENTIONS: In-person (n = 76) and telehealth (n = 52) follow-up visits. MAIN OUTCOME MEASUREMENTS: Victorian Institute of Sports Assessment-Achilles (VISA-A) for AT and Foot and Ankle Ability Measure (FAAM) for PF as well as billing level. RESULTS: There was significant improvement from baseline to final VISA-A (p < .01) and FAAM (p < .01) following ESWT. No significant difference existed in the proportion of patients who met the minimal clinically important difference based on in-person (71.1%) versus telehealth (71.2%) follow-up (p = .99). The in-person group demonstrated higher billing levels compared to the telehealth group (Level: 3.5 ± 0.6 vs. 2.8 ± 0.7, p < .01). CONCLUSIONS: Given no significant differences in outcomes between two modes of follow-ups, telehealth may serve as an alternative method to guide management of musculoskeletal injuries with ESWT and other procedures.

Digital Interventions for Social Participation in Adults with Long-term Physical Conditions: A Systematic Review.

This review aims to identify and evaluate digital interventions for social participation in the growing population of adults with long-term physical conditions. Articles were sourced from MEDLINE, EMBASE, CINAHL and PsycINFO databases using subject headings and keywords related to "social participation" and "digital technology". Studies that adopted digital technology interventions to improve social participation in adults with long-term physical conditions were included. Data on study methodology, participant and digital intervention characteristics, and findings related to social participation were extracted. The search yielded a total of 4646 articles and 14 articles met criteria for final review with five randomized controlled trials, two non-randomized clinical trials and seven one-group pretest-posttest clinical trials. Studies were organized based on the digital intervention strategy implemented to improve social participation: group support (n = 4), individual skill training or counseling (n = 6), education and support (n = 3), and mixed intervention (n = 1). The group support interventions developed a social network among participants through videoconference, app, or virtual reality platform. Three studies reported positive improvements in different aspects of social participation. Individual skill training or counseling mainly utilized phone calls to help participants cope with activity participation and interpersonal relationship issues. Only two studies demonstrated benefits for social participation. The education and support intervention, which used messages and website information to increase participants' knowledge and provide support, showed positive findings in three studies. This review suggests digital interventions for improving social participation in adults with long-term physical conditions are feasible and the effectiveness of different strategies may vary.Registration: This review was prospectively registered on the International Prospective Register of Systematic Reviews (PROSPERO) (registry number: CRD42021254105).

Prolotherapy: A Narrative Review of Mechanisms, Techniques, and Protocols, and Evidence for Common Musculoskeletal Conditions.

Prolotherapy is a nonsurgical regenerative technique that allows small amounts of irritant solution to be injected into the site of painful tendon and ligament insertions to promote the growth of healthy cells and tissues. The goal of prolotherapy is to stimulate growth factors that may strengthen attachments and reduce pain. Prolotherapy injection technique is centered around a focused physical examination and strong anatomic knowledge for maximized results. Prolotherapy is beneficial in a variety of different musculoskeletal conditions, including, but not limited to, lateral epicondylosis, rotator cuff tendinopathy, plantar fasciitis, Achilles tendinopathy, osteoarthritis, low back pain, sacroiliac joint pain, and TMJ laxity.

Peripheral Joint Injections.

Peripheral joint injections are a common interventional treatment of peripheral joint-mediated pain, including arthritis, tendinopathy, and bursitis that are not responsive to conservative management. Degenerative changes of articular joints are often related to these symptoms through chronic inflammatory changes, which typically arise due to repetitive trauma, autoimmune disease, or metabolic abnormalities. The primary diagnosis for degenerative disease in the peripheral joints is osteoarthritis but can also include rheumatoid arthritis, gout, and other less common etiologies. Chronic inflammatory damage to the articular surfaces and joint capsules can lead to pain and functional decline. As such, the use of peripheral joint injections after the failure of typical conservative treatment, including physical therapy and oral medications, is common. Although these injections are typically not curative in nature, their primary objective is to decrease pain to allow functional improvement concurrently with physical and pharmaceutical modalities. Common injectates used for peripheral joint injections include local anesthetic, corticosteroid, hyaluronic acid, platelet-rich plasma, and mesenchymal stromal cells.

Long term cost comparisons of radical cystectomy versus trimodal therapy for muscle-invasive bladder cancer.

BACKGROUND: Earlier studies on the cost of muscle-invasive bladder cancer treatments are limited to short-term costs of care. We determined the 2- and 5-year costs associated with trimodal therapy (TMT) vs. radical cystectomy (RC). METHODS: We performed a retrospective cohort study using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Total Medicare costs at 2 and 5 years following RC vs. TMT were compared using inverse probability of treatment-weighted propensity score models. RESULTS: A total of 2,537 patients aged 66 to 85 years were diagnosed with clinical stage T2-4a muscle-invasive bladder cancer. Total median costs for patients that received no definitive treatment(s) were $73,780 and $88,275 at 2-and 5-years. Costs were significantly higher for TMT than RC at 2-years ($372,839 vs. $191,363, Median Difference $127,815, Hodges-Lehmann Estimate (H-L) 95% Confidence Interval (CI), $112,663-$142,966) and 5-years ($424,570 vs. $253,651, Median Difference $124,466, H-L 95% CI, $105,711-$143,221). TMT had higher outpatient costs than RC (2-years: $318,221 vs. $100,900; 5-years: $367,092 vs. $146,561) with significantly higher costs with radiology, medications, pathology/laboratory, and other professional services. RC had higher inpatient costs than TMT (2-years: $62,240 vs. $33,631, Median Difference $-29,174, H-L 95% CI, $-32,364-$-25,984; 5-years: $75,499 vs. $45,223, Median Difference $-29,843, H-L 95% CI, $-33,905-$-25,781). CONCLUSIONS AND RELEVANCE: The excess spending associated with trimodal therapy vs. radical cystectomy was largely driven by outpatient expenditures. The relatively high long-term trimodal therapy costs are prime targets for cost containment strategies to optimize future value-based care.

Regulation of telomere homeostasis and genomic stability in cancer by N 6-adenosine methylation (m6A).

The role of RNA methylation on N 6-adenosine (m6A) in cancer has been acknowledged, but the underlying mechanisms remain obscure. Here, we identified homeobox containing 1 (HMBOX1) as an authentic target mRNA of m6A machinery, which is highly methylated in malignant cells compared to the normal counterparts and subject to expedited degradation upon the modification. m6A-mediated down-regulation of HMBOX1 causes telomere dysfunction and inactivation of p53 signaling, which leads to chromosome abnormalities and aggressive phenotypes. CRISPR-based, m6A-editing tools further prove that the methyl groups on HMBOX1 per se contribute to the generation of altered cancer genome. In multiple types of human cancers, expression of the RNA methyltransferase METTL3 is negatively correlated with the telomere length but favorably with fractions of altered cancer genome, whereas HMBOX1 mRNA levels show the opposite patterns. Our work suggests that the cancer-driving genomic alterations may potentially be fixed by rectifying particular epitranscriptomic program.

Impact of a Perioperative Protocol on Length of ICU and Hospital Stay in Complex Spine Surgery.

BACKGROUND: In an attempt to improve patient care, a perioperative complex spine surgery management protocol was developed through collaboration between spine surgeons and neuroanesthesiologists. The aim of this study was to investigate whether implementation of the protocol in 2015 decreased total hospital and intensive care unit (ICU) length of stay (LOS) and complication rates after elective complex spine surgery. MATERIALS AND METHODS: A retrospective cohort study was conducted by review of the medical charts of patients who underwent elective complex spine surgery at an academic medical center between 2012 and 2017. Patients were divided into 2 groups based on the date of their spine surgery in relation to implementation of the spine surgery protocol; before-protocol (January 2012 to March 2015) and protocol (April 2015 to March 2017) groups. Outcomes in the 2 groups were compared, focusing on hospital and ICU LOS, and complication rates. RESULTS: A total of 201 patients were included in the study; 107 and 94 in the before-protocol and protocol groups, respectively. Mean (SD) hospital LOS was 14.8±10.8 days in the before-protocol group compared with 10±10.7 days in the protocol group (P<0.001). The spine surgery protocol was the primary factor decreasing hospital LOS; incidence rate ratio 0.78 (P<0.001). Similarly, mean ICU LOS was lower in the protocol compared with before-protocol group (4.2±6.3 vs. 6.3±7.3 d, respectively; P=0.011). There were no significant differences in the rate of postoperative complications between the 2 groups (P=0.231). CONCLUSION: Implementation of a spine protocol reduced ICU and total hospital LOS stay in high-risk spine surgery patients.

A Positive Cocaine Urine Toxicology Test and the Effect on Intraoperative Hemodynamics Under General Anesthesia.

BACKGROUND: Cocaine has a short biological half-life, but inactive urine metabolites may be detectable for a week following use. It is unclear if patients who test positive for cocaine but have a normal electrocardiogram and vital signs have a greater percentage of hemodynamic events intraoperatively. METHODS: A total of 328 patients with a history of cocaine use who were scheduled for elective noncardiac surgery under general anesthesia were enrolled. Patients were categorized into cocaine-positive versus cocaine-negative groups based on the results of their urine cocaine toxicology test. The primary aim of this study was to evaluate whether asymptomatic cocaine-positive patients had similar percentages of intraoperative hemodynamic events, defined as (1) a mean arterial blood pressure (MAP) of <65 or >105 mm Hg and (2) a heart rate (HR) of <50 or >100 beats per minute (bpm) compared to cocaine-negative patients. The study was powered to assess if the 2 groups had an equivalent mean percent of intraoperative hemodynamic events within specific limits using an equivalence test of means consisting of 2 one-sided tests. RESULTS: The cocaine-positive group had a blood pressure (BP) that was outside the set limits 19.4% (standard deviation [SD] 17.7%) of the time versus 23.1% (SD 17.7%) in the cocaine-negative group (95% confidence interval [CI], 0.5-7.0). The cocaine-positive group had a HR outside the set limits 9.6% (SD 16.2%) of the time versus 8.2% (SD 14.9%) in the cocaine-negative group (95% CI, 4.3-1.5). Adjusted for age, sex, body mass index (BMI), smoking status, and the presence of comorbid hypertension, renal disease, and psychiatric illness, the cocaine-positive and cocaine-negative patients were similar within a 7.5% margin of equivalence for MAP data (ß coefficient = 2%, P = .003, CI, 2-6) and within a 5% margin of equivalence for HR data (ß coefficient = 0.2%, P < .001, CI, 4-3). CONCLUSIONS: Asymptomatic cocaine-positive patients undergoing elective noncardiac surgery under general anesthesia have similar percentages of intraoperative hemodynamic events compared to cocaine-negative patients.

Lumbar Spinal Stenosis and Potential Management With Prostaglandin E1 Analogs.

ABSTRACT: Lumbar spinal stenosis is one of the most commonly diagnosed spinal disorders worldwide and remains a major cause for surgery in older adults. Lumbar spinal stenosis is clinically defined as a progressive degenerative disorder with low back pain and associated neurogenic intermittent claudication. Conservative and surgical management of lumbar spinal stenosis has been shown to be minimally effective on its symptoms. A treatment option that has not been investigated in the United States is the utilization of prostaglandin E1 analogs, which have been used primarily in Japan for the treatment of lumbar spinal stenosis since the 1980s. The vasodilatory and antiplatelet aggregation effects of prostaglandin E1 presumably improve symptoms of lumbar spinal stenosis by increasing blood flow to the spinal nerve roots. This brief report examines the potential vascular pathology of lumbar spinal stenosis, reviews evidence on the use of prostaglandin E1 analog limaprost in Japan for lumbar spinal stenosis, and briefly discusses misoprostol as a possible alternative in the United States. The studies summarized in this report suggest that prostaglandin E1 analogs may provide benefit as a conservative treatment option for patients with lumbar spinal stenosis. However, higher-quality studies conducted in the United States and comparison with other currently used conservative treatments are required before it can be recommended for routine clinical use.

Botulinum Toxin A for Improving Lack of Ankle Dorsiflexion Range of Motion After Major Burns-A Retrospective Chart Review.

OBJECTIVE: To review the effectiveness of botulinum toxin A (BTX-A) for treating the loss of maximum ankle dorsiflexion range of motion after burn injury. DESIGN: Retrospective chart review. SETTING: Large urban burn center. PARTICIPANTS: Patients (3-51 y) with major burn injury and loss of ankle dorsiflexion range while hospitalized (N=5). INTERVENTION: BTX-A treatment in addition to standard care. MAIN OUTCOME MEASURES: Maximum ankle dorsiflexion range of motion at time of treatment, 1 month and 3 months posttreatment. RESULTS: Patients' total burn area ranged from 18% to 95%, and time from injury to BTX-A injection (80-125 units) was 19-93 days. Ankle range at the time of injection was -10 to -50 degrees, and all patients had improved ankle range at 1 month postinjection (-30 to +10 degrees). At 3 months postinjection, 3 participants had neutral ranges of motion that were relatively improved compared to preinjection ranges. Patients with additional complications or severe injury showed regression toward preinjection maximum ankle dorsiflexion range of motion. CONCLUSION: This retrospective study examines BTX-A as a potential tool for treating ankle plantar flexion contractures post major burn injury after failed conservative treatment. Initial review shows some patients may benefit from these injections, but more systematically designed studies are required to assess effectiveness. If effective, further investigation will be needed to validate and standardize treatment protocols, establish dosing, and assess long-term effectiveness in those with burn injury or severe complications.

Pharmacist Intentions to Prescribe Hormonal Contraception Following New Legislative Authority in California.

OBJECTIVE:: Following a California law expanding pharmacists' scope of practice to include directly providing self-administered hormonal contraception to patients pursuant to a statewide protocol, this study aimed to assess California pharmacists' intentions to provide this new service prior to the protocol development and implementation. DESIGN:: Descriptive, nonexperimental, cross-sectional study. SETTING:: California between August and September 2014. PARTICIPANTS:: California pharmacists working in community pharmacies. INTERVENTION:: Invitations to participate in the online survey were sent to 1774 pharmacists. MAIN OUTCOME MEASURES:: Main outcomes included pharmacists' current practices, intentions to prescribe hormonal contraception, comfort performing various activities, knowledge about contraceptive methods, training needs, and barriers to prescribing. RESULTS:: A total of 257 responses (14.5% response rate) were received. Of those, 121 respondents met inclusion criteria and were included in the analysis. About half of the respondents (49.6%) reported working in a community chain pharmacy, 46.3% in an independent pharmacy, and 4.1% in other community pharmacy settings. The majority (72.7%) of pharmacists reported that they would likely provide this new service. Respondents reported being comfortable educating patients on short-acting (94.2%) and long-acting reversible contraception (81.7%), as well as identifying drug interactions with hormonal contraception (96.7%). Respondents indicated time constraints (74.4%), lack of reimbursement (63.6%), and liability concerns (62.0%) as barriers to prescribing hormonal contraception. CONCLUSIONS:: California pharmacists expressed strong intentions and comfort in prescribing hormonal contraception. Pharmacists' additional training needs and barriers should be addressed for successful implementation. This new service has great potential to increase access to contraception, potentially fostering increased use and adherence.

Removal of strontium from drinking water by conventional treatment and lime softening in bench-scale studies.

The United States Environmental Protection Agency Contaminant Candidate List 3 lists strontium as a contaminant for potential regulatory consideration in drinking water. Very limited data is available on strontium removal from drinking water and as a result, there is an immediate need for treatment information. The objective of this work is to evaluate the effectiveness of coagulation/filtration and lime-soda ash softening treatment methods to remove strontium from surface and ground waters. Coagulation/filtration jar test results on natural waters showed that conventional treatment with aluminum and iron coagulants were able to achieve only 12% and 5.9% strontium removal, while lime softening removed as high as 78% from natural strontium-containing ground water. Controlled batch experiments on synthetic water showed that strontium removal during the lime-soda ash softening was affected by pH, calcium concentration and dissolved inorganic carbon concentration. In all softening jar tests, the final strontium concentration was directly related to the initial strontium concentration and the removal of strontium was directly associated with calcium removal. Precipitated solids showed well-formed crystals or agglomerates of mixed solids, two polymorphs of calcium carbonate (vaterite and calcite), and strontianite, depending on initial water quality conditions. X-ray diffraction analysis suggested that strontium was likely incorporated in the calcium carbonate crystal lattice and was likely responsible for removal during lime softening.

Perturbation of mitochondrial complex V alters the response to dietary restriction in Drosophila.

Studies in a broad spectrum of model organisms have reported that dietary restriction (DR) is associated with an increase in mitochondrial electron transport chain (ETC) function. However, the question of whether ETC function is required for DR-mediated longevity remains controversial. Here, we report that genetic and pharmacological interventions that target mitochondrial complex V affect Drosophila lifespan in a nutrient-dependent manner. These findings support a requirement for mitochondrial complex V in DR-mediated longevity in flies.
