Importance Evidence regarding suppressive valacyclovir treatment on postherpetic neuralgia is necessary to guide care. Objective To test the hypothesis that suppressive treatment with 1000 mg/d of oral valacyclovir for 12 months reduces the prevalence, severity, and duration of postherpetic neuralgia compared with placebo at 12 and 18 months in participants with herpes zoster ophthalmicus (HZO). Design, Setting, and Participants Multicenter, placebo-controlled randomized clinical trial including 527 immunocompetent, nonpregnant adults with history of HZO rash, documented keratitis, or iritis within 1 year and an estimated glomerular filtration rate of 45 mL/min/1.73 m 2 or greater. The study was conducted at 95 participating sites (in Canada, New Zealand, and the US) from November 2017 to June 2024 and participant visits occurred every 3 months. Intervention Treatment with 1000 mg/d of valacyclovir or placebo for 12 months. Main Outcomes and Measures Prevalence of postherpetic neuralgia, severity as determined by pain score (a score of ≥3 on a scale of 1-10), pain duration (≥3 months after HZO onset), and total daily dose of pain medication. Results Of the 527 participants (490 completed 12 months of treatment and 460 completed 18 months), 73 (14%) had postherpetic neuralgia and were analyzed by age at HZO onset (<60 years or ≥60 years) and disease duration (recent [<6 months] or chronic [≥6 months]). Of the 73 participants with postherpetic neuralgia (34 in the valacyclovir group and 39 in the placebo group), the mean age was 62.4 years (SD, 13.6 years), 59% were female, 5% were Black or African American, and 10% were Hispanic. The prevalence of postherpetic neuralgia at 12 months was not reduced by valacyclovir (12/32 [38%]) compared with placebo (14/35 [40%]) (between-group difference, 2.5% [95% CI, −20.8% to 25.8%]; P >.99). The participants who were younger than 60 years at HZO onset and had a chronic disease duration had lower pain scores in the valacyclovir group (mean score, 0.3 [SD, 0.9]) vs the placebo group (mean score, 0.8 [SD, 1.9]) at 12 months ( P = .045) and at 18 months (mean score, 0.2 [SD, 0.9] vs 1.0 [SD, 2.3], respectively; P = .02). There was a decrease in pain duration in the valacyclovir group at 18 months (mean, 13.6 [SD, 11.4] months) vs the placebo group (mean, 18.7 [SD, 29.5] months) (linear mixed-effects model between-group difference, −3.39 months [95% CI, −6.73 to −0.04 months]; P = .046). The total daily dose of neuropathic pain medication was lower in the valacyclovir group (mean, 271.4 [SD, 593.8] mg/d) vs the placebo group (mean, 363.4 [SD, 592.2] mg/d) at 12 months (linear mixed-effects model P = .006) and at 18 months (mean, 209.0 [SD, 412.8] mg/d vs 286.2 [SD, 577.9] mg/d, respectively; linear mixed-effects model P = .01). Conclusions and Relevance One year of suppressive treatment with valacyclovir was associated with a lower dosage of neuropathic pain medication. Participants in the valacyclovir group, who were younger at HZO onset and had a chronic disease duration, had lower pain scores. These secondary outcomes support consideration of 1 year of suppressive treatment with valacyclovir to reduce dosage of pain medications and pain due to HZO.

Objectives While extracorporeal shockwave therapy (ESWT) may be an efficacious adjunctive treatment option for musculoskeletal injuries, current research is limited by significant heterogeneity within treatment protocols. This study aims to establish international expert consensus recommendations on ESWT terminology, parameters, procedural considerations, contraindications and side effects in the application of ESWT to sports injuries. Methods A systematic literature search was performed on the use of ESWT for musculoskeletal and sports medicine injuries to identify potential panellists, followed by the development of a steering committee-led questionnaire. A three-stage, modified Delphi questionnaire was provided to a panel of 41 international clinical and research experts across 13 countries. Panellists had the opportunity to suggest edits to existing statements or recommend additional statements in Round 1. Consensus was defined as≥75% agreement. Results All 41 panellists completed Rounds 1, 2 and 3. Consensus was reached on 69/118 statements (58.5%), including recommendations on terminology and fundamental concepts, indications for use, procedural aspects for tendinopathy and bone pathologies, treatment correlations with imaging, periprocedural and postprocedural considerations, absolute and relative contraindications and potential side effects. Of the 49 statements that did not reach consensus, 17/49 (34.7%) were related to procedural aspects of bone pathology. Conclusion This international panel presents recommendations on ESWT terminology, indications and treatment considerations to guide ESWT use and decision-making by sports medicine clinicians. While our panel supported the use of ESWT in the treatment of bone pathologies, certain procedural aspects of ESWT specific to these injuries did not reach consensus and require further investigation.

ImportanceAcute promyelocytic leukemia (APL) is an acute illness that presents with cytopenia, infections, and disseminated intravascular coagulation. Achieving remission has been shown to make a major difference in patient outcomes; however, early death rates in the first month have been as high as 30% due to acute presentation, comorbidities, the rarity of APL, and clinician inexperience.ObjectiveTo develop treatment strategies that would decrease estimated 1-month mortality from 30% to below 15%.Design, Setting, and ParticipantsIn this nonrandomized clinical trial, a treatment algorithm that focused on supportive care was used to prevent early death in patients with APL treated at academic and community health centers between August 2017 and July 2021. Because of the rarity of the disease, expert support was available 24/7 from 7 designated APL experts at 6 participating academic lead centers, and included an additional 293 community centers. When a patient presented with APL, an expert was contacted and a consensus treatment plan was developed using the algorithm and expert suggestions. There were no exclusion criteria and all patients with a confirmed diagnosis of APL regardless of age or comorbid conditions were enrolled. Expert support was provided throughout induction. Initial data analysis was conducted May 2023.Main Outcomes and MeasuresOne-month mortality; additional objectives were to compare outcomes in academic and community centers and assess 1-year and overall survival.ResultsA total of 201 patients were enrolled from 43 centers; 62 at lead centers and 139 from 37 community centers. The median age was 53 years (range, 18-91 years), with 72 patients (35.8%) who were aged 60 years or older; 105 patients (52.2%) were male. Fifty-two patients (26.4%) were diagnosed with high-risk APL. The 1-month mortality rate was 6 deaths of 201 patients (3.0%; 95% CI, 1.1%-6.4%) after adjusting for 1 interim analysis. In a secondary analysis using the Kaplan-Meier method, the 1-month overall survival (OS) rate was 97.0% (95% CI, 93.5%-98.6%) and the 1-year OS rate was 94.5% (95% CI, 90.3%-96.9%).Conclusions and RelevanceIn this nonrandomized clinical trial, use of an algorithm combined with expert support resulted in a dramatic decrease in early death in academic and community centers. Population-wide survival improved in this highly curable disease, which suggests that implementing an accessible support system with APL experts for comanagement is the most logical next step.Trial RegistrationClinicalTrials.gov Identifier: NCT03253848

OBJECTIVES: Acute hypoxemic respiratory failure in immunocompromised patients remains the leading cause of admission to the ICU, with high case fatality. The response to the initial oxygenation strategy may be predictive of outcome. This study aims to assess the response to the evolutionary profiles of oxygenation strategy and the association with survival. DESIGN: Post hoc analysis of EFRAIM study with a nonparametric longitudinal clustering technique (longitudinal K-mean). SETTING AND PATIENTS: Multinational, observational prospective cohort study performed in critically ill immunocompromised patients admitted for an acute respiratory failure. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 1547 patients who did not require invasive mechanical ventilation (iMV) at ICU admission were included. Change in ventilatory support was assessed and three clusters of change in oxygenation modality over time were identified. Cluster A: 12.3% iMV requirement and high survival rate, n = 717 patients (46.3%); cluster B: 32.9% need for iMV, 97% ICU mortality, n = 499 patients (32.3%); and cluster C: 37.5% need for iMV, 0.3% ICU mortality, n = 331 patients (21.4%). These clusters demonstrated a high discrimination. After adjustment for confounders, clusters B and C were independently associated with need for iMV (odds ratio [OR], 9.87; 95% CI, 7.26–13.50 and OR, 19.8; 95% CI, 13.7–29.1). CONCLUSIONS: This study identified three distinct highly performing clusters of response to initial oxygenation strategy, which reliably predicted the need for iMV requirement and hospital mortality.

Background Intra-articular corticosteroid (IACS) injection and peri-articular corticosteroid injection are commonly used to treat musculoskeletal conditions. Results vary by musculoskeletal region, but most studies report short-term benefit with mixed results on long-term relief. Publications showed adverse events from single corticosteroid injections. Recommended effective doses were lower than those currently used by clinicians. Methods Development of the practice guideline for joint injections was approved by the Board of Directors of the American Society of Regional Anesthesia and Pain Medicine and the participating societies. A Corticosteroid Safety Work Group coordinated the development of three guidelines: peripheral nerve blocks and trigger points; joints; and neuraxial, facet, and sacroiliac joint injections. The topics included safety of the technique in relation to landmark-guided, ultrasound-guided, or radiology-aided injections; effect of the addition of the corticosteroid on the efficacy of the injectate; and adverse events related to the injection. Experts on the topics were assigned to extensively review the literature and initially develop consensus statements and recommendations. A modified version of the US Preventive Services Task Force grading of evidence and strength of recommendation was followed. A modified Delphi process was adhered to in arriving at a consensus. Results This guideline focuses on the safety and efficacy of corticosteroid joint injections for managing joint chronic pain in adults. The joints that were addressed included the shoulder, elbow, hand, wrist, hip, knee, and small joints of the hands and feet. All the statements and recommendations were approved by all participants and the Board of Directors of the participating societies after four rounds of discussion. There is little evidence to guide the selection of one corticosteroid over another. Ultrasound guidance increases the accuracy of injections and reduces procedural pain. A dose of 20 mg triamcinolone is as effective as 40 mg for both shoulder IACS and subacromial subdeltoid bursa corticosteroid injections. The commonly used dose for hip IACS is 40 mg triamcinolone or methylprednisolone. Triamcinolone 40 mg is as effective as 80 mg for knee IACS. Overall, IACS injections result in short-term pain relief from a few weeks to a few months. The adverse events include an increase in blood glucose, adrenal suppression, detrimental effect on cartilage lining the joint, reduction of bone mineral density, and postoperative joint infection. Conclusions In this practice guideline, we provided specific recommendations on the role of corticosteroids in joint, bursa, and peritendon injections for musculoskeletal pain.

Background Sexual health is influenced by a complex interplay of biological, psychological, and social factors, all of which can be impacted by Parkinson's disease (PD). Female sexual dysfunction includes reduced sexual desire and/or arousal, pain during sexual activity, or difficulty achieving orgasm. Despite its impact on quality of life, sexual health in women with PD remains poorly understood. Objective To investigate the impact of motor, non-motor, and social PD aspects on sexual health of women with PD. Methods We conducted a cross-sectional study with 100 women with PD (Hoehn and Yahr stages 1–3) who reported an active sex life in the last six months. Data were collected via remote interviews and included demographic and clinical features, cognitive capacity, motor and non-motor experiences, fatigue, self-esteem, sleep disorders, couple relationship quality, depressive symptoms, and sexual health assessments using the Female Sexual Function Index (FSFI) and Sexual Quotient-Female (SQ-F). Multiple regression models were used to identify predictors of FSFI and SQ-F scores. Results Results indicated that while several motor, non-motor, and social factors correlated with sexual health, only couple relationship quality and sleep quality significantly predicted both short-term (FSFI) and long-term (SQ-F) sexual health. No significant associations were observed with age, disease onset, postmenopausal status, or daily medication dosage. Conclusions The present study's evidence identifies multiple key areas, such as couple's relationship quality and sleep quality that could be targeted for intervention to improve sexual health in women with PD.

Abstract Background Inter‐fractional and intra‐fractional positioning and motion monitoring based on implanted fiducials through kilovoltage (kV) imaging is a cost‐effective approach to enhance intact prostate radiotherapy treatment accuracy. However, comprehensive studies for three‐dimensional (3D) position extraction and the corrective action threshold are lacking. Purpose To develop and verify a fiducial motion monitoring system with 3D position information based on triggered kV images taken during treatment delivery, and to comprehensively evaluate the recommended thresholds for corrective action during treatment. Methods An in‐house fiducial triangulation algorithm was developed to monitor fiducial positions using subsequent kV triggered images. The precision of fiducial triangulation and motion detection was validated on a pelvis phantom with four fiducial inserts. A retrospective study was conducted on prostate cancer patients who received either moderately hypofractionated radiotherapy (MHRT, n = 16) or stereotactic body radiotherapy (SBRT, n = 12), categorized by endo‐rectal balloon (ERB) use. Intra‐fractional positions relative to isocenter were computed, and these positions were analyzed in comparison to the original marker locations of the patient's treatment plan. A linear regression fit was used per fraction to determine correlation coefficients between motions in the left–right (LR), superior–inferior (SI), and anterior–posterior (AP) directions. Average fraction time (AFT) of treatment was reported based on the observed average time spent on steps in the workflow and the percentage of fiducials caught outside of the current two‐dimensional (2D) tolerance threshold of 5 mm. The observed 3D offsets were used to estimate AFT for various 3D tolerance thresholds. Results Overall, our triangulation method proved to be very precise for static cases, where phantom measurements revealed a fiducial position triangulation precision of mm for stationary targets, but had a spread of mm for targets with 1 mm of motion. Employing triangulation, true motion exceeding 5 mm was detected above 4.0 mm in magnitude 90.9% of the time, a noticeable improvement in comparison to the 28%–65% successful detection rate reported by 2D projection methods. Most detection errors were attributed to depth disparity. Similar to other reports, correlation coefficients for intra‐fractional motion generally indicated no LR/SI, no LR/AP, and weak positive SI/AP correlations for MHRT and SBRT patients. Offsets beyond a 3D tolerance threshold of 5 mm were observed at a rate of 4.25%–5.25%, while the 5 mm 2D out‐of‐tolerance catch‐rate was 1.6%. The AFT was 8.1–8.2 min using the 2D tolerance threshold of 5 mm. In comparison, the estimated AFT for the proposed 3D tolerance monitoring of offsets beyond 2–5 mm was slightly higher at 8.2–10.9 min due to the higher amount of out‐of‐tolerance instances for the higher precision intra‐fractional motion management. Conclusions Our study showcases a promising subsequent kV‐based triangulation method for intra‐fractional prostate motion monitoring. Acquiring 3D motion information results in higher out‐of‐tolerance catch‐rates particularly in the depth dimension of the kV images, which is perpendicular to the treatment beam. Failure to properly observe and catch these offsets would result in sub‐optimal conformality and accuracy of the dose delivery.

Objective: To assess patient radiation exposure as reflected by cumulative air kerma (CAK) and dose area product (DAP) during fenestrated-branched endovascular aortic repair (FB-EVAR). Background: Patient radiation exposure during FB-EVAR has been reported inconsistently. Methods: Data from 2,111 patients enrolled in 10 physician-sponsored investigational device exemption studies (2012-2022) were analyzed from the United States Aortic Research Consortium database. Procedures were performed using seven fixed imaging systems (A to G). Patients were classified into three groups by imaging era: 2012-2015 (Group 1), 2016-2018 (Group 2), and 2019-2022 (Group 3). Primary endpoints were CAK and DAP risk factors, assessed using linear mixed-effect models. Secondary endpoints were diagnostic reference levels (DRL) for FB-EVAR. Results: Of the 2,111 patients (71% males; mean 74±9 years years-old) treated by FB-EVAR; 263 (12%) were in Group 1, 541 (26%) in Group 2, and 1,307 (62%) in Group 3. Use of ≥4 vessel stent-graft designs increased from 69% (Group 1) to 79% (Group 3) ( P <0.001). Median CAK decreased from 3,644 mGy (Group 1) to 1,753 mGy (Group 3), and DAP from 441 Gy.cm² to 208 Gy.cm² ( P <0.001). Higher BMI, iliac branch device (IBD) use, and longer fluoroscopy time (FT) were associated with increased CAK and DAP, while experienced operators and systems D, F, and G were protective ( P <0.05). DRLs for Group 3 were 2,800 mGy (CAK) and 340 Gy.cm² (DAP). Conclusions: Radiation exposure during FB-EVAR significantly decreased over time. Higher BMI, IBD use, and FT were linked to increased exposure, while experienced operator and System D, F or G were protective.

Background: Patients presenting with non-ST elevation myocardial infarction (NSTEMI) are often admitted to medical wards. We aimed to evaluate the impact of the admitting department on long-term outcomes. Methods: Patients admitted to a large tertiary center were categorized according to the admission ward, either the intensive cardiac care unit (ICCU) or internal medicine department (IMD). We compared major adverse cardiovascular events (MACEs), a composite of all-cause death, recurrent myocardial infarction (MI), and revascularization, along with the individual components of MACE, between the two groups during a long-term follow-up. Results: A total of 11,779 NSTEMI patients were included, with 4522 admitted to the ICCU and 7257 to the department of internal medicine. Patients admitted to the ICCU had lower systolic blood pressure, higher troponin levels and lower left ventricular ejection fraction (LVEF) compared to those in the IMD group, indicating greater initial clinical severity. Although patients admitted to the ICCU experienced a significantly higher rate of in-hospital complications, there were no significant differences in the incidence of in-hospital deaths between the two groups. During 5-year follow-up, NSTEMI patients initially admitted to the ICCU had significantly lower rates of mortality and MACEs. The estimated hazard ratio for 5-year MACE and 5-year mortality rates for NSTEMI patients admitted to the IMD vs. those admitted to the ICCU were 2.03 (95% CI, 1.04–3.34) and 2.5 (95% CI, 1.10–4.38), respectively. Conclusions: NSTEMI patients admitted to the ICCU experienced lower long-term mortality and MACE rates. These findings support the management of NSTEMI patients in cardiac wards and warrant further research into the reasons for the improved outcome.
