A systematic evaluation of youtube as an information source for male infertility.
International journal of impotence research
This study evaluates YouTube videos (YTVs) focused on male infertility to assess information quality and identify high-quality content that can reliably facilitate care. Top 50 YTVs based on relevance were identified using the keyword "male infertility." A checklist, adapted from American Urological Association guidelines addressing male infertility, was developed to assess YTV content. Two investigators extracted YTV features (including duration, likes, views, upload date), classified creators and ranked YTVs based on checklist scores. YTVs were then assigned grades A-D based on checklist scores. Kruskal-Wallis test and ANOVA were employed to draw associations between grades, content creator, and YTV features. Higher grades were associated with shorter video duration (p=0.0305). Most YTVs (23/42) were created by healthcare-related organizations. Of the 42 YTVs included in the final analysis, 31% (13/42) explicitly defined infertility as an inability to conceive after 12 months of unprotected intercourse. Ninety percent (38/42) discussed male infertility evaluation methods, while 71% (30/42) discussed various interventions. Various content creators have adopted YouTube to discuss male infertility, and healthcare practitioners should be aware of YouTube's potential influence on patient understanding of male infertility. Knowledge gaps identified in YTVs can help improve patient counseling and enable practitioners to direct patients to reliable content.

Co-Manifestations of Genital Neurofibromatosis in a Patient with Neurofibromatosis Type 1.
Genitourinary (GU) presentation of neurofibromatosis type 1 (NF-1) is rare, amongst which bladder involvement is the most common. Sporadic case reports do highlight infrequent external genitalia involvement in NF-1. We present a 21-year-old male with prior childhood history of partial cystectomy for an NF-1 related bladder tumor, who more recently presented with gross hematuria. Workup revealed multiple ganglioneuromas involving the bladder, prostate, and penis, and the patient underwent radical cystoprostatectomy and penile mass excision. Recurrences of previously excised urologic tumors or new tumors may appear many years later, and long-term monitoring of NF-1 patients with urologic involvement is necessary.

Boda Bodas and Road Traffic Injuries in Uganda: An Overview of Traffic Safety Trends from 2009 to 2017.
International journal of environmental research and public health
2020; 17 (6)
INTRODUCTION: Road traffic injuries (RTIs) are an important contributor to the morbidity and mortality of developing countries. In Uganda, motorcycle taxis, known as boda bodas, are responsible for a growing proportion of RTIs. This study seeks to evaluate and comment on traffic safety trends from the past decade.METHODS: Traffic reports from the Ugandan police force (2009 to 2017) were analyzed for RTI characteristics. Furthermore, one month of casualty ward data in 2015 and 2018 was collected from the Mulago National Referral Hospital and reviewed for casualty demographics and trauma type.RESULTS: RTI motorcycle contribution rose steadily from 2009 to 2017 (24.5% to 33.9%). While the total number of crashes dropped from 22,461 to 13,244 between 2010 and 2017, the proportion of fatal RTIs increased from 14.7% to 22.2%. In the casualty ward, RTIs accounted for a greater proportion of patients and traumas in 2018 compared to 2015 (10%/41% and 36%/64%, respectively).CONCLUSIONS: Although RTIs have seen a gross reduction in Uganda, they have become more deadly, with greater motorcycle involvement. Hospital data demonstrate a rising need for trauma and neurosurgical care to manage greater RTI patient burden. Combining RTI prevention and care pathway improvements may mitigate current RTI trends.

A Cost-Effectiveness Analysis of Corticosteroid Injections and Open Surgical Release for Trigger Finger.
The Journal of hand surgery
To evaluate the cost-effectiveness of corticosteroid injection(s) versus open surgical release for the treatment of trigger finger.Using a US health care payer perspective, we created a decision tree model to estimate the costs and outcomes associated with 4 treatment strategies for trigger finger: offering up to 3 steroid injections before to surgery or immediate open surgical release. Costs were obtained from a large administrative claims database. We calculated expected quality-adjusted life-years for each treatment strategy, which were compared using incremental cost-effectiveness ratios. Separate analyses were performed for commercially insured and Medicare Advantage patients. We performed a probabilistic sensitivity analysis using 10,000 second-order Monte Carlo simulations that simultaneously sampled from the uncertainty distributions of all model inputs.Offering 3 steroid injections before surgery was the optimal strategy for both commercially insured and Medicare Advantage patients. The probabilistic sensitivity analysis showed that this strategy was cost-effective 67% and 59% of the time for commercially insured and Medicare Advantage patients, respectively. Our results were sensitive to the probability of injection site fat necrosis, success rate of steroid injections, time to symptom relief after a steroid injection, and cost of treatment. Immediate surgical release became cost-effective when the cost of surgery was below $902 or $853 for commercially insured and Medicare Advantage patients, respectively.Multiple treatment strategies exist for treating trigger finger, and our cost-effectiveness analysis helps define the relative value of different approaches. From a health care payer perspective, offering 3 steroid injections before surgery is a cost-effective strategy.Economic and Decision Analyses II.

Operative Versus Nonoperative Management of Appendicitis: A Long-Term Cost Effectiveness Analysis.
MDM policy & practice
2019; 4 (2): 2381468319866448
Background. Recent clinical trials suggest that nonoperative management (NOM) of patients with acute, uncomplicated appendicitis is an acceptable alternative to surgery. However, limited data exist comparing the long-term cost-effectiveness of nonoperative treatment strategies. Design. We constructed a Markov model comparing the cost-effectiveness of three treatment strategies for uncomplicated appendicitis: 1) laparoscopic appendectomy, 2) inpatient NOM, and 3) outpatient NOM. The model assessed lifetime costs and outcomes from a third-party payer perspective. The preferred strategy was the one yielding the greatest utility without exceeding a $50,000 willingness-to-pay threshold. Results. Outpatient NOM cost $233,700 over a lifetime; laparoscopic appendectomy cost $2500 more while inpatient NOM cost $7300 more. Outpatient NOM generated 24.9270 quality-adjusted life-years (QALYs), while laparoscopic appendectomy and inpatient NOM yielded 0.0709 and 0.0005 additional QALYs, respectively. Laparoscopic appendectomy was cost-effective compared with outpatient NOM (incremental cost-effectiveness ratio $32,300 per QALY gained); inpatient NOM was dominated by laparoscopic appendectomy. In one-way sensitivity analyses, the preferred strategy changed when varying perioperative mortality, probability of appendiceal malignancy or recurrent appendicitis after NOM, probability of a complicated recurrence, and appendectomy cost. A two-way sensitivity analysis showed that the rates of NOM failure and appendicitis recurrence described in randomized trials exceeded the values required for NOM to be preferred. Limitations. There are limited NOM data to generate long-term model probabilities. Health state utilities were often drawn from single studies and may significantly influence model outcomes. Conclusion. Laparoscopic appendectomy is a cost-effective treatment for acute uncomplicated appendicitis over a lifetime time horizon. Inpatient NOM was never the preferred strategy in the scenarios considered here. These results emphasize the importance of considering long-term costs and outcomes when evaluating NOM.

Cost-effectiveness of Canakinumab for Prevention of Recurrent Cardiovascular Events.
Importance: In the Canakinumab Anti-inflammatory Thrombosis Outcome Study (CANTOS) trial, the anti-inflammatory monoclonal antibody canakinumab significantly reduced the risk of recurrent cardiovascular events in patients with previous myocardial infarction (MI) and high-sensitivity C-reactive protein (hs-CRP) levels of 2 mg/L or greater.Objective: To estimate the cost-effectiveness of adding canakinumab to standard of care for the secondary prevention of major cardiovascular events over a range of potential prices.Design, Setting, and Participants: A state-transition Markov model was constructed to estimate costs and outcomes over a lifetime horizon by projecting rates of recurrent MI, coronary revascularization, infection, and lung cancer with and without canakinumab treatment. We used a US health care sector perspective, and the base case used the current US market price of canakinumab of $73 000 per year. A hypothetical cohort of patients after MI aged 61 years with an hs-CRP level of 2 mg/L or greater was constructed.Interventions: Canakinumab, 150 mg, administered every 3 months plus standard of care compared with standard of care alone.Main Outcomes and Measures: Lifetime costs and quality-adjusted life-years (QALYs), discounted at 3% annually.Results: Adding canakinumab to standard of care increased life expectancy from 11.31 to 11.36 years, QALYs from 9.37 to 9.50, and costs from $242 000 to $1 074 000, yielding an incremental cost-effectiveness ratio of $6.4 million per QALY gained. The price would have to be reduced by more than 98% (to $1150 per year or less) to meet the $100 000 per QALY willingness-to-pay threshold. These results were generally robust across alternative assumptions, eg, substantially lower health-related quality of life after recurrent cardiovascular events, lower infection rates while receiving canakinumab, and reduced all-cause mortality while receiving canakinumab. Including a potential beneficial effect of canakinumab on lung cancer incidence improved the incremental cost-effectiveness ratio to $3.5 million per QALY gained. A strategy of continuing canakinumab selectively in patients with reduction in hs-CRP levels to less than 2 mg/L would have a cost-effectiveness ratio of $819 000 per QALY gained.Conclusions and Relevance: Canakinumab is not cost-effective at current US prices for prevention of recurrent cardiovascular events in patients with a prior MI. Substantial price reductions would be needed for canakinumab to be considered cost-effective.

Use of gasotransmitters for the controlled release of polymer-based nitric oxide carriers in medical applications
JOURNAL OF CONTROLLED RELEASE
2018; 279: 157–70
Nitric Oxide (NO) is a small molecule gasotransmitter synthesized by nitric oxide synthase in almost all types of mammalian cells. NO is synthesized by NO synthase by conversion of l-arginine to l-citrulline in the human body. NO then stimulates soluble guanylate cyclase, from which various physiological functions are mediated in a concentration-dependent manner. High concentrations of NO induce apoptosis or antibacterial responses whereas low NO circulation leads to angiogenesis. The bidirectional effect of NO has attracted considerable attention, and efforts to deliver NO in a controlled manner, especially through polymeric carriers, has been the topic of much research. This naturally produced signaling molecule has stood out as a potentially more potent therapeutic agent compared to exogenously synthesized drugs. In this review, we will focus on past efforts of using the controlled release of NO via polymer-based materials to derive specific therapeutic results. We have also added studies and our future suggestions on co-delivery methods with other gasotransmitters as a step towards developing multifunctional carriers.
