Efficient recall of SARS‐CoV‐2 variant‐reactive B cells and T responses in the elderly upon heterologous mRNA vaccines as boosters

alexandrossfakianakis shared this article with you from Inoreader Efficient recall of SARS‐CoV‐2 variant‐reactive B cells and T responses in the elderly upon heterologous mRNA vaccines as boosters via Journal of Medical Virology Abstract Waning antibody levels against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and the emergence of variants of concern (VOC) highlight the need for booster vaccinations. This is particularly important for the elderly population, who are at a higher risk of developing severe Coronavirus disease 2019 (COVID-19) disease. Whilst studies have shown increased antibody responses following booster vaccination, understanding the changes in T and B cell compartments induced by a third vaccine dose remains limited. We analysed the humoral and cellular responses in subjects who received either a homologous mRNA booster vaccine (BNT162b2+BNT162b2+BNT162b2; 'BBB') or a heterologous mRNA booster vaccine (BNT162b2+BNT162b2+mRNA-1273; 'BBM') at day 0 (pre-booster), day 7 and day 28 (post-booster). Compared to BBB, elderly individuals (≥60 years old) who received the BBM vaccination regimen display higher levels of neutralising antibodies a gainst the Wuhan and Delta strains along with a higher boost in IgG memory B cells, particularly against the Omicron variant. Circulating Th1, Th2, Th17 and Tfh responses were also increased in elderly individuals given the BBM regimen. While mRNA vaccines increase antibody, T cell and B cell responses against SARS-CoV-2 one month after receiving the third dose booster, the efficacy of the booster vaccine strategies may vary depending on age group and regimen combination.

The Use of Dissemination and Implementation to Improve Multimodal Analgesia in Head and Neck Surgery

alexandrossfakianakis shared this article with you from Inoreader The Use of Dissemination and Implementation to Improve Multimodal Analgesia in Head and Neck Surgery via The Laryngoscope The use of a multimodal analgesia approach in a Randomized Clinical Trial including acetaminophen, ketorolac, gabapentin, and a neurogenic extremity block in patients undergoing major head and neck ablative and reconstructive surgery significantly reduced the need for opioids in the immediate postoperative period of a seven-day hospital stay. Coordination of care and reducing variability in pain medication administration were highly dependent on dissemination and implementation processes put in place for perioperative phases of care. Objectives To optimize the delivery of multimodal analgesia to patients undergoing major head and neck oncologic surgeries. Methods Pilot study included patients enrolled to receive either scheduled acetaminophen and as-needed opioids (control group) or scheduled acetaminophen, gabapentin, ketorolac, and as-needed opioids (experimental group). RCT, a hybrid type 1 effectiveness-implementation pragmatic trial, was designed to test the effectiveness of the intervention. Arm A received scheduled acetaminophen and as-needed opioids. Arm B received scheduled gabapentin, ketorolac, a regional nerve block at the free tissue donor site, scheduled acetaminophen and as-needed opioids. Results Pilot: Thirty-one patients undergoing major head and neck surgery were enrolled. Mean MMEs administered in control group (n = 15) was 251.60 mg (SD = 224.57 mg); mean MMEs in Experimental group (n = 16) was 195.78 mg (SD = 131.08 mg), p = 0.401. LOS was 8.0 days in control versus 7.0 days in experimental group (p = 0.054). RCT: Interim analysis for safety and futility was planned during trial's design after 30 patients (n = 14 Arm A, and n = 16 Arm B). Mean MMEs administered were 135.1 mg in Arm A, (SD = 86.0 mg) versus mean MME of 51.3 mg in Arm B (SD = 43.3 mg, (p < 0.05)). Given clear superiority results, the trial was prematurely terminated. Functional pain scores, LOS, and complications were similar between the arms (p > 0.05). Variability of mean MME was compared before and after implementation of the management protocols: SD in RCT#1 was 181.46 mg versus 124.6 mg in RCT#2. Conclusion Multimodal analgesia significantly reduced the need for opioids in patients undergoing major head and neck surgery.

The evolution of fertility preservation care models in a large pediatric cancer and blood disorders center

alexandrossfakianakis shared this article with you from Inoreader The evolution of fertility preservation care models in a large pediatric cancer and blood disorders center via Pediatric Blood & Cancer Abstract Background Children and adolescents who receive gonadotoxic treatments are at risk for future infertility. While there is a growing focus on integrating fertility preservation (FP) within pediatric cancer and blood disorder centers, wide variations in care models and methods exist across institutions. The purpose of this work is to describe the evolution of FP care models within a large pediatric hematology/oncology center. Methods Models of care and associated timeframes are described, including a pre-FP program model, establishment of a formal FP program, integration of nurse navigators, and the addition of FP consult stratification based on urgency (urgent/nonurgent). The number of patient consults within each model, patient sex, diagnosis (oncologic/hematologic), and consult timing (pre-gonadotoxic treatment/posttreatment completion) were abstracted from the clinical database. Results The number of annual consults increased from 24 during the pre-FP program model (2015) to 181 during the current care model (2020). Over time, the proportion of consults for females and patients with nonmalignant hematologic disorders increased. Patient stratification reduced the proportion of consults needing to be completed urgently from 75% at the advent of the FP program to 49% in the current model. Conclusions The evolution of care models within our FP program allowed for growth in the number of consults completed, expansion of services to more patients with nonmalignant hematologic disorders, and more consults for female patients. Nurse navigators play a critical role in care facilitating referrals, coordination, and patient education. Urgency stratification has allowed FP team members to manage increasing FP-related encounters. View on Web

Off‐label pharmacological treatment for neuropathic pain: A Delphi study by the Spanish Pain Society Neuropathic Pain Task Force

alexandrossfakianakis shared this article with you from Inoreader Off‐label pharmacological treatment for neuropathic pain: A Delphi study by the Spanish Pain Society Neuropathic Pain Task Force via Pain Practice Abstract Objectives The use of off-label pharmacotherapies for neuropathic pain (NP) is growing relating to the many unmet needs of patients. However, clinical guidelines fail to address it, and the available evidence is sparse and fragmented. We arranged a formal expert consensus to address this controversial issue and provide some guidance on judicious use. Methods A two-round standard Delphi survey that involved pain clinic specialists with experience in the research and management of NP was done over an ad hoc 40-item questionnaire prepared by the authors. Consensus on each statement was defined as at least either 80% endorsement or rejection after the second round. Results Forty-three and thirty-seven panelists participated in the first and second round, respectively. Consensus was reached in 34 out of 40 statements. Endorsed alternatives for unresponsive patients include non-gabapentinoid antiepileptics (oxcarbazepine and eslicarbazepine), venlafaxine, intravenous lidocaine (when doses can be optimized), and some vaporized cannabinoids (under appropriate surveillance). In addition, lacosamide, low-dose naltrexone, propofol or ketamine could prove beneficial if subjected to more research. Other options were rejected, and there was controversy about the usefulness of topical preparations. Discussion For patients who do not respond to standard NP treatments, some other viable pharmacological options can be attempted before advancing to other therapeutic stages. This may help patients who are reluctant to or have some contraindication for interventional therapies. View on Web

Computational fluid dynamics and NOSE scale to assess nasal respiratory function, and correlation with linear maxillary measurements after surgically assisted rapid maxillary expansion

alexandrossfakianakis shared this article with you from Inoreader Computational fluid dynamics and NOSE scale to assess nasal respiratory function, and correlation with linear maxillary measurements after surgically assisted rapid maxillary expansion via International Journal of Oral and Maxillofacial Surgery via MedWorm.com Nasal obstruction is common in patients with a transverse maxillary deficiency. The aim of this study was to determine the variation in nasal airway resistance in adult patients with a transverse maxillary deficiency before and after surgically assisted rapid maxillary expansion (SARME) by computational fluid dynamics (CFD) using computed tomography scans, and to correlate this variation with maxillary linear measurements obtained by means of plaster models. The subjective symptoms of nasal obstruction were also analysed using a visual analogue scale (VAS) for nasal breathing and the Nasal Obstruction Symptom Evaluation (NOSE) scale.
