A Research Agenda for Helminth Diseases of Humans: Diagnostics for Control and Elimination Programmes

Diagnostic tools appropriate for undertaking interventions to control helminth infections are key to their success. Many diagnostic tests for helminth infection have unsatisfactory performance characteristics and are not well suited for use in the parasite control programmes that are being increasingly implemented. Although the application of modern laboratory research techniques to improve diagnostics for helminth infection has resulted in some technical advances, uptake has not been uniform. Frequently, pilot or proof of concept studies of promising diagnostic technologies have not been followed by much needed product development, and in many settings diagnosis continues to rely on insensitive and unsatisfactory parasitological or serodiagnostic techniques. In contrast, PCR-based xenomonitoring of arthropod vectors, and use of parasite recombinant proteins as reagents for serodiagnostic tests, have resulted in critical advances in the control of specific helminth parasites. The Disease Reference Group on Helminths Infections (DRG4), established in 2009 by the Special Programme for Research and Training in Tropical Diseases (TDR) was given the mandate to review helminthiases research and identify research priorities and gaps. In this review, the diagnostic technologies relevant to control of helminth infections, either available or in development, are reviewed. Critical gaps are identified and opportunities to improve needed technologies are discussed

A Research Agenda for Helminth Diseases of Humans: Basic Research and Enabling Technologies to Support Control and Elimination of Helminthiases

Successful and sustainable intervention against human helminthiases depends on optimal utilisation of available control measures and development of new tools and strategies, as well as an understanding of the evolutionary implications of prolonged intervention on parasite populations and those of their hosts and vectors. This will depend largely on updated knowledge of relevant and fundamental parasite biology. There is a need, therefore, to exploit and apply new knowledge and techniques in order to make significant and novel gains in combating helminthiases and supporting the sustainability of current and successful mass drug administration (MDA) programmes. Among the fields of basic research that are likely to yield improved control tools, the Disease Reference Group on Helminth Infections (DRG4) has identified four broad areas that stand out as central to the development of the next generation of helminth control measures: 1) parasite genetics, genomics, and functional genomics; 2) parasite immunology; 3) (vertebrate) host–parasite interactions and immunopathology; and 4) (invertebrate) host–parasite interactions and transmission biology. The DRG4 was established in 2009 by the Special Programme for Research and Training in Tropical Diseases (TDR). The Group was given the mandate to undertake a comprehensive review of recent advances in helminthiases research in order to identify notable gaps and highlight priority areas. This paper summarises recent advances and discusses challenges in the investigation of the fundamental biology of those helminth parasites under the DRG4 Group's remit according to the identified priorities, and presents a research and development agenda for basic parasite research and enabling technologies that will help support control and elimination efforts against human helminthiases

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10 years; 78.2% included were male with a median age of 37 years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

A Comparative Analysis of Outcomes using PROMIS after Operative vs Non-operative Treatment of Achilles Rupture

Introduction/Purpose: Achilles tendon rupture is a common injury in the adult population. The role of operative and non- operative management remains controversial with the development of functional rehabilitation programs. The purpose of this study is to evaluate and compare the patient-reported outcomes using Patient-Reported Outcomes Measurement Information System (PROMIS) after operative and non-operative treatment of acute Achilles rupture. PROMIS is a valid, reliable, and effective tool to evaluate patient outcomes after treatment for Achilles ruptures. Our hypothesis is that there is no significant difference in PROMIS scores between patients undergoing operative compared to non-operative treatment of Achilles rupture. Methods: Under an IRB-approved protocol, Achilles rupture was identified using ICD 9 and ICD10 codes of 727.67 and S86.0. Patients who underwent Achilles tendon primary repair were identified using CPT code 27650 (Repair, primary open or percutaneous, ruptured Achilles tendon). Revision Achilles repair and chronic Achilles ruptures were excluded. All patients treated non-operative underwent a strict functional rehabilitation protocol. We included patients treated between 1/1/2015 and 11/30/2022. PROMIS physical function (PF), pain interference (PI), and depression scores were routinely collected prospectively during the initial office visit and follow-up appointments. A distribution-based method used to determine the minimal clinically important difference (MCID), which was 1/2 standard deviation of each PROMIS domain. A medical records review was performed to collect patient demographic data. Statistical analysis was used to compare preoperative and postoperative scores and significance was indicated when P< 0.05. Results: 216 patients with Achilles tendon ruptured were included (115 Nonoperative versus 101 Operative). Patients treated non-operatively were older than those treated surgically (mean age: 45.1 vs 35.6; p< 0.001). The operative group had a lower BMI compared to non-operative group (27.8 vs. 29.5; p=0.004). There is no statistical difference in the Achilles tendon re-rupture rate between both groups (operative: 2% vs. 4.3%; p=0.344). Both groups are effective in improving PROMIS PF, PI, and depression scores (p < 0.001). The mean PROMIS PF change (pre- to post-treatment) is significantly greater in the operative, compared to the non-operative group (13.2 vs. 9.5; p=0.042). Both treatments had similar mean PROMIS PI change, mean PROMIS depression change, and rates of meeting MCID for all 3 PROMIS domains at 6 months. Conclusion: In patients with Achilles tendon rupture, operative management may lead to statistically significant higher improvements in physical function compared to non-operative management. However, non-operative management was associated with similar overall rates of re-rupture, PROMIS PI and depression outcomes, and chances of meeting MCID as those who underwent operative intervention. Nonoperative management of Achilles tendon rupture, similar to operative treatment, is a successful treatment option and leads to significant improvement in physical function, pain interference, and depression PROMIS scores

Patient Reported Outcomes using PROMIS after Tarsal Tunnel Release Surgery

Category: Other Introduction/Purpose: Tarsal tunnel syndrome is an entrapment neuropathy of the tibial nerve and its branches in the tarsal tunnel. The literature on surgical release of the tarsal tunnel shows variable outcomes with no studies reporting validated patient reported outcomes. We aim to determine clinical response after tarsal tunnel release using the Patient-Reported Outcomes Measurement Information System (PROMIS). Methods: Under an IRB-approved protocol, CPT code 28035 was used to identify patients who underwent isolated tarsal tunnel release (TTR) between 1/1/2015 and 12/15/2022 at a single institution. Patient demographic data and PROMIS CAT physical function (PF), pain interference (PI), and depression scores were prospectively collected at the initial pre-operative clinic visit and in follow-up throughout the episode of care after TTR. The validated distribution-based method (1/2 sd) was used to assess minimal clinically important difference (MCID). Bivariate analysis was used to determine the postoperative recovery after TTR. Statistical significance was set at p< 0.05. Results: A total of 39 patients who underwent tarsal tunnel release were included. The mean age was 49.1 years (19.44-70.75 years) and mean follow-up was 280.9 days (23-1,459 days). The mean PROMIS PF score improved from 38.97 preoperatively to 46.17 postoperatively (p-value= 0.0024). The mean PROMIS PI score improved from 63.75 preoperatively to 57.65 postoperatively (p-value < 0.001). The mean PROMIS depression score improved from 49.78 preoperatively to 43.85 postoperatively (p-value < 0.001). The mean t-score change (pre to post-operation) was 7.2 for PF, -6.1 for PI, and -5.93 for depression. MCID thresholds were calculated as PF increase of 4.7; PI decrease of 3.9; and Depression decrease of 5.1. Fourteen (35%), 24 (62%), and 27 (69%) patients reached MCID for PF, PI, and depression, respectively. Conclusion: This study provides validated outcomes after TTR. Though there is improvement after surgery, the patients still experience some pain and physical limitations. Interestingly, the greatest gains were seen in depression symptoms supporting the idea that mental health is impacted in these chronic compressive neuropathy conditions
