Multinational Association of Supportive Care in Cancer (MASCC) clinical practice guidelines for the prevention and management of acute radiation dermatitis: international Delphi consensus-based recommendations.

Acute radiation dermatitis is a frequent adverse effect of radiotherapy, but standardisation of care for acute radiation dermatitis is lacking. Due to the conflicting evidence and variability in current guidelines, a four-round Delphi consensus process was used to compile opinions of 42 international experts on care for people with acute radiation dermatitis on the basis of the evidence in existing medical literature. Interventions for acute radiation dermatitis prevention or management that reached at least 75% consensus were recommended for clinical use. Six interventions could be recommended for the prevention of acute radiation dermatitis: photobiomodulation therapy and Mepitel film in people with breast cancer, Hydrofilm, mometasone, betamethasone, and olive oil. Mepilex Lite dressings were recommended for the management of acute radiation dermatitis. Most interventions were not recommended due to insufficient evidence, conflicting evidence, or lack of consensus to support use, suggesting a need for further research. Clinicians can consider implementing recommended interventions in their practice to prevent and manage acute radiation dermatitis until additional evidence becomes available.

Comparison of clinical practice guidelines on radiation dermatitis: a narrative review.

PURPOSE: Radiation dermatitis (RD) is a common side effect of radiation therapy (RT). While many different treatment strategies are currently used to address RD, there is a lack of consensus and RD prophylaxis and management guidelines have remained largely unchanged over the last 10 years. This review aims to formulate unambiguous supportive care interventions by comparing RD clinical practice guidelines published between 2010 and 2021 by several organizations: Multinational Association for Supportive Care in Cancer (MASCC), British Columbia Cancer Agency (BCCA), Cancer Care Manitoba (CCMB), Oncology Nursing Society (ONS), Society and College of Radiographers (SCoR), and International Society of Nurses in Cancer Care (ISNCC). METHODS: Areas of agreement and discordance were assessed among the MASCC, BCCA, CCMB, ONS, SCoR, and ISNCC guidelines. RESULTS: Treatment recommendations across guidelines for acute RD and chronic RT-induced skin toxicities have been summarized. The strongest agreement among the guidelines exists for the use of topical corticosteroids, silver sulfadiazine, washing, and deodorant. All guidelines recommend the use of topical corticosteroids, and washing with water and soap is consistently supported. There is minimal consensus on an optimal dressing or barrier film for RD prophylaxis or management. MASCC weakly recommends prophylactic use of silver sulfadiazine to reduce RD, while BCCA, CCMB, and SCoR recommend its use upon signs of infection. MASCC and CCMB recommend the use of a long-pulsed dye laser to manage telangiectasia, a late effect of RT. CONCLUSIONS: Given the extent of discordance among guideline recommendations, further research is recommended to establish optimal treatments for RD prophylaxis and management.

Current quality of life assessment tools may not fully address dermatological adverse events from anti-cancer therapies.

Supportive oncodermatology is a burgeoning new field within dermatology tasked with caring for the unique dermatologic needs of patients with cancer. Patients with dermatologic adverse events (dAEs) from localized and systemic anti-cancer therapies commonly experience significant distress and reduced health-related quality of life (HRQoL). Emerging dAEs is often overlooked by clinicians and researchers, despite their considerable impacts on treatment completion and patient self-esteem. Specific HRQoL issues experienced by cancer patients with dAEs include psychosocial distress and treatment interruption or cessation. Existing HRQoL assessment indices unfortunately fall short when assessing HRQoL in patients with dAEs from anti-cancer therapies due to the lack of specificity to patients' symptoms and inability to fully encompass the unique needs of this population. Additionally, the variability in HRQoL assessments across studies is substantial, suggesting the need for a standardized HRQoL measure. Here, we review the burden of dAEs and the existing validated tools used to measure them, while outlining strategies for modification to achieve optimal HRQoL assessment in patients with dAEs from anti-cancer therapies and address the HRQoL gap in supportive oncodermatology. Amongst the current tools, Skindex-16 most closely addresses the required skin-specific HRQoL metrics, but still lacks a few key cancer-specific measures. Other general HRQoL tools are well-tailored to cancer patients, but lack skin-specific questions.

Adductor canal block with or without added magnesium sulfate following total knee arthroplasty: a multi-arm randomized controlled trial.

PURPOSE: Postoperative analgesia following total knee arthroplasty (TKA) often includes intrathecal opioids, periarticular injection (PAI) of local anesthetic, systemic multimodal analgesia, and/or peripheral nerve blockade. The adductor canal block (ACB) provides analgesia without muscle weakness and magnesium sulphate (MgSO4) may extend its duration. The purpose of this trial was to compare the duration and quality of early post-TKA analgesia in patients receiving postoperative ACB (± MgSO4) in addition to standard care. METHODS: Elective TKA patients were randomized to: 1) sham ACB, 2) ropivacaine ACB, or 3) ropivacaine ACB with added MgSO4. All received spinal anesthesia with intrathecal morphine, intraoperative PAI, and multimodal systemic analgesia. Patients and assessors remained blinded to allocation. Anesthesiologists knew whether patients had received sham or ACB but were blinded to MgSO4. The primary outcome was time to first analgesic (via patient-controlled analgesia [PCA] with iv morphine) following ACB. Secondary outcomes were morphine consumption, side effects, visual analogue scale pain scores, satisfaction until 24 hr postoperatively, and length of stay. RESULTS: Of 130 patients, 121 were included. Nine were excluded post randomization: four were protocol violations, three did not meet inclusion criteria, and two had severe pain requiring open label blockade. There were no differences in the median [interquartile range] time to first PCA request: sham, 310 min [165-550]; ropivacaine ACB, 298 min [120-776]; and ropivacaine ACB with MgSO4, 270 min [113-780] (P = 0.96). Similarly, we detected no differences in resting pain, opioid consumption, length of stay, or associated side effects until 24 hr postoperatively. CONCLUSION: We found no analgesic benefit of a postoperative ACB, with or without added MgSO4, in TKA patients undergoing spinal anesthesia and receiving intrathecal morphine, an intraoperative PAI, and multimodal systemic analgesia.

RéSUMé: OBJECTIF: L'analgésie postopératoire suivant une arthroplastie totale du genou (ATG) inclut souvent des opioïdes intrathécaux, une injection périarticulaire (IPA) d'anesthésique local, une analgésie multimodale systémique, et/ou des blocs des nerfs périphériques. Le bloc du canal des adducteurs (BCA) permet une analgésie sans faiblesse musculaire et le sulfate de magnésium (MgSO4) pourrait prolonger sa durée. L'objectif de cette étude était de comparer la durée et la qualité de l'analgésie post-ATG précoce chez les patients recevant un BCA postopératoire (± MgSO4) en plus des soins standard. MéTHODE: Des patients devant subir une ATG non urgente ont été randomisés à recevoir : 1) un BCA placebo (groupe témoin), 2) un BCA avec ropivacaïne, ou 3) un BCA avec ropivacaïne et MgSO4. Tous ont reçu une rachianesthésie avec morphine intrathécale, une IPA peropératoire, et une analgésie multimodale systémique. L'allocation a été faite à l'insu des patients et des évaluateurs. Les anesthésiologistes savaient si les patients avaient reçu un placebo ou un BCA, mais n'étaient pas informés de l'ajout ou non de MgSO4. Le critère d'évaluation principal était le temps jusqu'à la première prise d'analgésique (via une analgésie contrôlée par le patient [ACP] avec de la morphine iv) après le BCA. Les critères secondaires comprenaient la consommation de morphine, les effets secondaires, les scores de douleur sur l'échelle visuelle analogue, la satisfaction jusqu'à 24 heures postopératoires, et la durée de séjour. RéSULTATS: Sur 130 patients, 121 ont été inclus. Neuf ont été exclus après la randomisation : quatre l'ont été en raison de violations du protocole, trois ne répondaient pas aux critères d'inclusion, et deux ont ressenti des douleurs graves nécessitant un bloc sans insu. Aucune différence n'a été observée dans le temps médian [écart interquartile] jusqu'à la première demande d'ACP : placebo, 310 min [165-550]; BCA ropivacaïne, 298 min [120-776]; et BCA ropivacaïne avec MgSO4, 270 min [113-780] (P = 0,96). De la même manière, nous n'avons détecté aucune différence dans la douleur au repos, la consommation d'opioïdes, la durée de séjour, ou les effets secondaires associés jusqu'à 24 heures postopératoires. CONCLUSION: Nous n'avons trouvé aucun avantage analgésique à un BCA postopératoire, avec ou sans ajout de MgSO4, chez les patients subissant une ATG sous rachianesthésie et recevant de la morphine intrathécale, une IPA peropératoire, et une analgésie multimodale systémique.

Using concept mapping to inform the development of a transitional reintegration intervention program for formerly incarcerated people with HIV.

BACKGROUND: Accessing HIV-related care is challenging for formerly incarcerated people with HIV. Interventions informed by the perspectives of these individuals could facilitate engagement with care and address competing priorities that may act as barriers to this process. METHODS: We used concept mapping to identify and prioritize the main obstacles to engaging with HIV-related care following prison release. In brainstorming sessions, formerly incarcerated people with HIV generated responses to a focused prompt regarding the main barriers to reengaging with care. These were consolidated in 35 statements. Next, participants sorted the consolidated list of responses into groups and rated each from lowest to highest in terms of its importance and feasibility of being addressed. We used cluster analysis to generate concept maps that were interpreted with participants. RESULTS: Overall, 39 participants participated in brainstorming sessions, among whom 18 returned for rating and sorting. Following analysis, a seven-cluster map was generated, with participants rating the 'Practical Considerations' (e.g. lack of transportation from prison) and 'Survival Needs' (e.g. securing housing and food) clusters as most important. Although ratings were generally similar between women and men, women assigned greater importance to barriers related to reconnecting with children. CONCLUSIONS: Using concept mapping, we worked with formerly incarcerated people with HIV to identify and prioritize key challenges related to accessing health and social services following prison release. Transitional intervention programs should include programs and processes that address meeting basic subsistence needs and overcoming logistical barriers related to community re-entry.

MASCC clinical practice guidelines for the prevention and management of acute radiation dermatitis: part 1) systematic review.

Acute radiation dermatitis (ARD) commonly develops in cancer patients undergoing radiotherapy and is often characterized by erythema, desquamation, and pain. A systematic review was conducted to summarize the current evidence on interventions for the prevention and management of ARD. Databases were searched from 1946 to September 2020 to identify all original studies that evaluated an intervention for the prevention or management of ARD, with an updated search conducted in January 2023. A total of 235 original studies were included in this review, including 149 randomized controlled trials (RCTs). Most interventions could not be recommended due to a low quality of evidence, lack of supporting evidence, or conflicting findings across multiple trials. Photobiomodulation therapy, Mepitel® film, mometasone furoate, betamethasone, olive oil, and oral enzyme mixtures showed promising results across multiple RCTs. Recommendations could not be made solely based on the published evidence due to limited high-quality evidence. As such, Delphi consensus recommendations will be reported in a separate publication.

Relationship Between Left Ventricular Strain Assessment by Cardiac Magnetic Resonance Imaging and Response to Cardiac Resynchronization Therapy.

Although cardiac resynchronization therapy (CRT) is an established treatment for heart failure with reduced ejection fraction, 30 to 50% patients are non-responders. In this retrospective single-centre study, 19 patients underwent cardiac MRI pre-CRT, and global left ventricular (LV) strain and late gadolinium enhancement (LGE) were measured by a blinded reader. LV reverse remodeling was independently assessed using transthoracic echocardiogram before and after CRT implant. Both LV strain and extent of LGE correlated significantly with measures of reverse LV remodeling (reduction in LV volume and improvement in LV ejection fraction). These findings suggest that CMR derived strain analysis and scar evaluation may be useful preimplant predictors of response to CRT. Larger prospective multi-center studies are needed to confirm these findings and to further evaluate the role of CMR strain imaging in guiding CRT treatment decisions.
