Local Flaps for Concomitant Reconstruction of 3 Adjacent Forehead Defects: Is It Feasible?

The cornerstones of forehead reconstruction are the provision of adequate skin paired with a satisfactory cosmetic outcome without hairline and eyebrows distortion. Several techniques have been described over the years to reconstruct sizable defects. Currently, an individualized approach, based on the patient's medical status and needs, the defect characteristics, and the local tissue quality and availability, should be considered for an optimal outcome. This case exemplifies the reliability of local flaps' combination to reconstruct concurrently 3 adjacent forehead defects, should innovative thinking and adequate planning be applied.

Clinical Audit on the practice of Documentation during Preanesthetic evaluation

Pre-anesthesia checkups play a crucial role in ensuring patient safety and positive outcomes during surgical procedures. These assessments are typically conducted before surgery to evaluate the patient's overall health, identify potential risks, and tailor anesthetic plans accordingly. The efficacy of pre-anesthesia checkups can be assessed based on several factors: Risk Identification: Pre-anesthesia evaluations help identify pre-existing medical conditions, allergies, or other factors that could pose a risk during surgery. Recognizing and addressing potential complications beforehand can contribute to better preparation and management during the perioperative period. Optimization of Patient Conditions: Through pre-anesthesia assessments, healthcare providers can work to optimize a patient's medical condition before surgery, such as controlling blood pressure, managing diabetes, or addressing respiratory issues. This optimization can contribute to a smoother anesthesia experience and faster recovery post-surgery. Tailored Anesthetic Plans: Based on the information gathered during the pre-anesthesia checkup, anesthesiologists can develop individualized anesthetic plans that consider the patient's medical history, current health status, and the nature of the surgical procedure. Tailoring the anesthesia approach helps in minimizing complications and adverse reactions. Informed Decision-Making: The pre-anesthesia evaluation allows for informed decision-making by both the patient and the medical team. Patients can be educated about the potential risks and benefits of anesthesia, and their concerns can be addressed before the procedure. Reduced Complication Rates: By addressing potential issues proactively, pre-anesthesia checkups contribute to reducing the occurrence of complications during and after surgery. This, in turn, can lead to improved patient outcomes and a lower likelihood of adverse events. Postoperative Recovery: Adequate pre-anesthetic evaluation and optimization can positively impact the patient's recovery after surgery. Patients who undergo thorough pre-anesthetic assessments are more likely to have a smoother recovery process with fewer complications. Efficient Resource Utilization: Pre-anesthesia checkups help identify patients who may require additional monitoring, specialized equipment, or specific interventions during surgery. This allows for efficient allocation of resources and personnel to address individual patient needs. In conclusion, the efficacy of pre-anesthesia checkups on patient outcomes is well-established. These assessments contribute to safer surgical experiences, reduced complications, and improved overall outcomes by allowing for tailored, informed, and proactive care.

Integrating artificial intelligence into a real-world clinical pathway to facilitate clinician treatment optimisation in patients with HFrEF on suboptimal medical therapy

Abstract Background Despite evidence-based pharmacological recommendations, many patients with HFrEF remain undertreated. (1) These patients remain at risk of decompensation and might benefit treatment optimisation. Many patients may also have been diagnosed with HFrEF prior to the use of sacubitril/valsartan or SGLT2 inhibitors. Identification of patients with historical HF diagnosis is time-consuming. Artificial intelligence approaches using deep learning might allow rapid identification of such patients. Aim To develop an artificial intelligence deep-learning algorithm for rapid identification of HF from electronic health records (EHRs) and to determine the potential benefit of our AI-driven algorithm for the detection of undertreated HFrEF patients in the community. Methodology In this study data was collected from EHRs of 1,200 patients who underwent transthoracic echocardiography. The records were screened to identify HF diagnosis through an AI deep-learning algorithm using a Convolutional Neural Network (CNN). Medication status of patients identified as having HFrEF was assessed to determine whether they were on optimal guideline-directed medical therapy. Accuracy of the AI algorithm was assessed by a manual clinician review in a subset of 150 patients. Eligible patients not on optimal medical therapy where no further optimisation was planned (judged to be "stable" at last visit) were invited for a clinical evaluation including NT-proBNP and Kansas City Cardiomyopathy Questionnaire (KCCQ) and offered a treatment optimization that could include either uptitration or initiation of a new medication if symptomatic. NT-proBNP and KCCQ were repeated at 12 week, pre- and post-optimization results were compared to evaluate patient outcomes. Results The deep-learning algorithm accurately identified HFrEF patients (99%) and use of RAAS inhibitors (97%) and beta-blockers (92%). 73 patients attended for initial clinical assessment (mean age 70 years, 77% male) and demonstrated a moderate level of HF-symptom burden (median NT-proBNP was 679 pg/mL, interquartile range was from 220 to 1300) and mean KCCQ overall summary score was 70, indicating a moderate level of HF symptom burden. 27 patients agreed to treatment optimisation. After 12 weeks there was a significant 22% reduction in NT-proBNP (from 1991 pg/mL (SD+/- 1796) to 1630 pg/mL (SD +/- 1588),p=0.049) and improvements in KCCQ (total symptom score 79 (+/-22) to 85 (+/-20), p=0.005; clinical summary score 78 (+/-23) to 82 (+/-20); overall summary score from 75 (+/- 24) to 80 (+/-22), both p=0.04). 23 patients (85%) and 18 patients (67%) out of 27 had an improvement in NT-proBNP and KCCQ overall summary scores respectively. Conclusion In our study we demonstrated the feasibility and potential benefits incorporating AI into a clinical workflow, allowing optimising treatment of patients with HF, with improvements in biomarkers and quality of life that could translate to long-term patient benefits.Changes in NT-proBNP after treatmentChanges in KCCQ after treatment

Atrial Natriuretic Peptide and Cardiovascular Diseases in Dogs and Cats

The term biomarker encompasses various biological indicators that objectively reflect a patient's medical status with precision and reproducibility. These indicators range from basic measurements like pulse and blood pressure to more intricate laboratory tests. Cardiac markers are crucial for accurate and prompt diagnosis of heart diseases in animals. Given the challenge of diagnosing cardiac diseases in small animals due to nonspecific clinical signs, cardiac markers provide quantitative indicators of biological processes. These markers include cardiac troponins for myocardial injury, natriuretic peptides for myocardial function, lipoproteins for serum homeostasis, and markers for inflammation of the cardiovascular system. Among natriuretic peptides, atrial natriuretic peptide (ANP) has emerged as a significant tool in diagnosing and monitoring cardiac diseases. ANP, primarily synthesized in cardiac atria, regulates salt and fluid excretion, counteracts vasoconstriction, and inhibits the renin-angiotensin-aldosterone system, contributing to the maintenance of cardiovascular homeostasis. Additionally, it functions as a biomarker for ventricular hypertrophy and congestive heart failure (CHF) in animals. Furthermore, it protects against hypertension and cardiac remodeling by demonstrating antagonism to the same system. This review addresses the definition of biomarkers within the context of molecular biology, elucidates their multifaceted functions in the animal organism in light of integrative physiology, and explores the pathologies correlated with ANP, with an emphasis on its etiopathogenesis and clinical manifestations.

Effective and safe pediatric sedation.

Pediatric sedation is a crucial tool for minimizing pain and anxiety during procedures and examinations in children. However, it is not without risks. This review provides a comprehensive review of pediatric sedation, including both established practices and recent advancements. A thorough pre-procedural evaluation is crucial to mitigate these risks. Skilled healthcare professionals trained in pediatric sedation are paramount to ensure a safe and effective procedure. The choice of sedative medication depends on various factors, such as the type of procedure and the patient's medical condition. Medications, used alone or in combination, offer sedation with varying onset times and durations. Non-pharmacological approaches can complement pharmacological sedation and further reduce potential complications. Preventing sedation-related complications requires a multidisciplinary approach. This includes collaborative decision-making, vigilant monitoring throughout the procedure, and a focus on patient safety. Recovery involves ensuring the child returns to their baseline status before discharge, following established criteria. In conclusion, successful pediatric sedation hinges on a comprehensive strategy. This strategy encompasses a thorough evaluation, skilled personnel, appropriate medication selection, vigilant monitoring, and a focus on patient safety throughout the process. By following these steps, we can minimize risks and achieve successful outcomes.

The Economic Impact of Community Paramedics Within Emergency Medical Services: A Systematic Review.

Globally, emergency medical services (EMSs) report that their demand is dominated by non-emergency (such as urgent and primary care) requests. Appropriately managing these is a major challenge for EMSs, with one mechanism employed being specialist community paramedics. This review guides policy by evaluating the economic impact of specialist community paramedic models from a healthcare system perspective. A multidisciplinary team (health economics, emergency care, paramedicine, nursing) was formed, and a protocol registered on PROSPERO (CRD42023397840) and published open access. Eligible studies included experimental and analytical observational study designs of economic evaluation outcomes of patients requesting EMSs via an emergency telephone line ('000', '111', '999', '911' or equivalent) responded to by specialist community paramedics, compared to patients attended by usual care (i.e. standard paramedics). A three-stage systematic search was performed, including Peer Review of Electronic Search Strategies (PRESS) and Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). Two independent reviewers extracted and verified 51 unique characteristics from 11 studies, costs were inflated and converted, and outcomes were synthesised with comparisons by model, population, education and reliability of findings. Eleven studies (n = 7136 intervention group) met thecriteria. These included one cost-utility analysis (measuring both costs and consequences), four costing studies (measuring cost only) and six cohort studies (measuring consequences only). Quality was measured using Joanna Briggs Institute tools, and was moderate for ten studies, and low for one. Models included autonomous paramedics (six studies, n = 4132 intervention), physician oversight (three studies, n = 932 intervention) and/or special populations (five studies, n = 3004 intervention). Twenty-one outcomes were reported. Models unanimously reduced emergency department (ED) transportation by 14-78% (higher quality studies reduced emergency department transportation by 50-54%, n = 2639 intervention, p < 0.001), and costs were reduced by AU$338-1227 per attendance in four studies (n = 2962). One study performed an economic evaluation (n = 1549), finding both that the costs were reduced by AU$454 per attendance (although not statistically significant), and consequently that the intervention dominated with a > 95% chance of the model being cost effective at the UK incremental cost-effectiveness ratio threshold. Community paramedic roles within EMSs reduced ED transportation by approximately half. However, the rate was highly variable owing to structural (such as local policies) and stochastic (such as the patient's medical condition) factors. As models unanimously reduced ED transportation-a major contributor to costs-they in turn lead to net healthcare system savings, provided there is sufficient demand to outweigh model costs and generate net savings. However, all models shift costs from EDs to EMSs, and therefore appropriate redistribution of benefits may be necessary to incentivise EMS investment. Policymakers for EMSs could consider negotiating with their health department, local ED or insurers to introduce a rebate for successful community paramedic non-ED-transportations. Following this, geographical areas with suitable non-emergency demand could be identified, and community paramedic models introduced and tested with a prospective economic evaluation or, where this is not feasible, with sufficient data collection to enable a post hoc analysis.

Carbapenem Versus Non-carbapenem Therapy in Hematology Patients: Extended-Spectrum Beta-Lactamase Positive Enterobacteriaceae Colonization Impact.

Extended-spectrum beta-lactamase-producing Enterobacteriacea (ESBL-E) infections are a major source of mortality and morbidity in patients with hematologic cancers. One of the most significant risk factors for bacterial illness is prior colonization with resistant germs. Empiric usage of carbapenems is recommended for the treatment of infections in patients with a positive colonization history. We aimed to determine the outcome of empirical carbapenem (de-escalation) versus non-carbapenem (escalation) therapy in adult hematology patients who have rectal extended-spectrum beta-lactamase positive ESBL-Ecolonization. Two hundred three rectal swab cultures were collected from 130 patients, admission or during hospitalization between June 2014andMay 2015. Patients were followed till January 2016 for future infections due to ESBL-E. Empirical antibiotic treatment was started according to the patient's medical condition without consideration of previous colonization status. Stable patients received empirical escalation therapy. All-cause and early mortality of infections are analyzed. Seventy-three (36%) swabs were positive for ESBL-E. Patients with rectal ESBL-E colonization were defined as cases; patients without colonization were defined as controls. Prospective infection due to ESBL-E in the case and control group was 6.8% and 2.3%, respectively. No statistically significant relation was found between colonization and prospective infection due to ESBL-E (p=0.110). There was no all-cause or early mortality in prospective infections with ESBL-E.Among case patients, one patient each died from all-cause mortality in the escalation (n=55) and de-escalation (n=3) group.The all-cause mortality in the antibiotic switch group (n=30) was eight, including five patients in the early mortality group although the bacteriologic agents were susceptible to the given antibiotics. In our institution, rectal colonization with ESBL-E was high, but contracting an infection due to ESBL-E was surprisingly low. Colonization with ESBL-E may not necessarily end with an infection in some situations. In stable patients, disregarding colonization features before empirical therapy did not seem to be inappropriate.

Fitness to Work in a Hansen's Disease Worker With a Disability: A Case Report.

Hansen's disease not only causes problems for patients in the workplace, but also increases the possibility of transmission to other workers. This case report discusses the fitness-to-work assessment for a Hansen's disease patient with a disability. A 19-year-old female, who worked as an online shop warehouse staff, presented at our hospital with a wound on her left hand accompanied by numbness. The patient's activity indicated mild limitations with a SALSA score of 25. A seven-step process for evaluating fitness to work was conducted. These steps involved assessing the patient's medical condition, disability, job demands, risks, and tolerance to determine the appropriate work status. This patient was declared fit to work with a note as online shop warehouse staff. She must take care of herself by maintaining good personal hygiene and consulting a doctor regularly, in addition to educating other workers about her condition and avoiding stigma. Routine examinations are also an important part of treating leprosy in the workplace.

A Post-International Gastrointestinal Cancers' Conference (IGICC) Position Statements.

Hepatocellular carcinoma (HCC), the most prevalent liver tumor, is usually linked with chronic liver diseases, particularly cirrhosis. As per the 2020 statistics, this cancer ranks 6th in the list of most common cancers worldwide and is the third primary source of cancer-related deaths. Asia holds the record for the highest occurrence of HCC. HCC is found three times more frequently in men than in women. The primary risk factors for HCC include chronic viral infections, excessive alcohol intake, steatotic liver disease conditions, as well as genetic and family predispositions. Roughly 40-50% of patients are identified in the late stages of the disease. Recently, there have been significant advancements in the treatment methods for advanced HCC. The selection of treatment for HCC hinges on the stage of the disease and the patient's medical status. Factors such as pre-existing liver conditions, etiology, portal hypertension, and portal vein thrombosis need critical evaluation, monitoring, and appropriate treatment. Depending on the patient and the characteristics of the disease, liver resection, ablation, or transplantation may be deemed potentially curative. For inoperable lesions, arterially directed therapy might be an option, or systemic treatment might be deemed more suitable. In specific cases, the recommendation might extend to external beam radiation therapy. For all individuals, a comprehensive, multidisciplinary approach should be adopted when considering HCC treatment options. The main treatment strategies for advanced HCC patients are typically combination treatments such as immunotherapy and anti-VEGFR inhibitor, or a combination of immunotherapy and immunotherapy where appropriate, as a first-line treatment. Furthermore, some TKIs and immune checkpoint inhibitors may be used as single agents in cases where patients are not fit for the combination therapies. As second-line treatments, some treatment agents have been reported and can be considered.

An Overview of Pharmaceutical Reconciliation

During the move between healthcare settings and changes in the medical status of patients, it is very important to update the correct drug regimen according to the clinical conditions to avoid the possibility of medical errors. Nearly half of medication errors occur during initial admission, transfer between hospital departments, and before discharge. Among these errors, about 30% of cases have the potential of seriously harming the patient. Some risk factors, such as old age and the number of drugs used, are associated with an increased risk of medication discrepancies. The medication reconciliation process can significantly reduce the risk of potential errors. It includes obtaining, verifying, and documenting a list of the patient's current medications and comparing it to the patient's medication orders and condition to identify and resolve any discrepancies. Comparing what is being prescribed in one setting with what is being taken in another will prevent errors of drug-drug interactions, omission, and other discrepancies. Pharmaceutical reconciliation is an important element of patient safety and rational drug use, and it can significantly contribute to the health economy.

ANALYSIS OF THE IMPLEMENTATION OF THE SOCIAL SECURITY ADMINISTERING AGENCY'S (BPJS) PATIENT REFERRAL SYSTEM AT PIDIE DISTRICT HEALTH CENTER.

Background: The referral system is still a problem in the health sector and its implementation is still not in accordance with existing regulations. This can be seen from the still high number of referrals at community health centres. There are several things that cause the referral rate to remain high, such as a lack of understanding by health workers regarding the vertical referral system and horizontal referral system. Many patients also lack information about referrals, which results in these patients tending to prefer to receive secondary services. Objective: To find out how to implement the Health Insurance Administering Agency (BPJS) patient referral system at the Pidie Regency health centre. Research Method: This research is qualitative research. As for There were 12 informants related to the implementation of the referral system determined in this research. Results: The referral implementation that has been carried out at 3 community health centres in the Aceh Pidie area is a tiered referral from the community health centre to the hospital with a choice of hospitals according to the needs of the patient's medical condition and the hospital contained in the P Care application. Obstacles faced by community health centres in implementing the referral system include requests for referrals by patients and the referral process not yet running optimally from specialist doctors on duty at the hospital. Suggestion: Researchers suggest that the head of the community health centre should carry out monitoring and evaluation every month to be able to take intervention measures in an effort to provide training for the P Care application staff at the health centre and supporting community health centres so that the P Care application data input will be controlled every month in inputting patient visit data so that the ratio can be achieved. referrals as expected, namely 15% every month.

A Mixed Methods Analysis of Standardized Documentation of Serious Illness Conversations Within an Electronic Health Record Module During Hospitalization.

Analysis of documented Serious Illness Conversations (SICs) in the inpatient setting can help clinicians align management to address patient and caregiver needs. We conducted a mixed methods analysis of the first instance of standardized documentation of a SIC within a structured module among hospitalized general medicine patients from 2018 to 2019. Percentage of documentations that included a description of patient or family understanding of the patient's medical condition and use of radio buttons to answer the "prognostic information shared," "hopes," and "worries" modules are reported. Using grounded theory approach, physicians analyzed free text entries to: "What is important to the patient/family?" and "Recommendations or next steps planned." Out of 5142 patients, 59 patients had a documented SIC. Patient or family understanding of the medical condition(s) was reported in 56 (95%). For "prognostic information shared," the most frequently selected radio buttons were: 49 (83%) incurable disease and 28 (48%) prognosis of weeks to months while those for "hopes" were: 52 (88%) be comfortable and 27 (46%) be at home and for "worries" were: 49 (83%) other physical suffering and 36 (61%) pain. Themes generated from entries to "What's important to patient/family?" included being with loved ones; comfort; mentally and physically present; and reliable care while those for "Recommendations" were coordinating support services; symptom management; and support and communication. SIC content indicated concern about pain and reliable care suggesting the complex, intensive nature of caring for seriously ill patients and the need to consider SICs earlier in the life course of patients.

FEA Comparison of the Mechanical Behavior of Three Dental Crown Materials: Enamel, Ceramic, and Zirconia.

The restoration of endodontically treated teeth is one of the main challenges of restorative dentistry. The structure of the tooth is a complex assembly in which the materials that make it up, enamel and dentin, have very different mechanical behaviors. Therefore, finding alternative replacement materials for dental crowns in the area of restorative care isa highly significant challenge, since materials such as ceramic and zirconia have very different stress load resistance values. The aim of this study is to assess which material, either ceramic or zirconia, optimizes the behavior of a restored tooth under various typical clinical conditions and the masticatory load. A finite element analysis (FEA) framework is developed for this purpose. The 3D model of the restored tooth is input into the FEA software (Ansys Workbench R23)and meshed into tetrahedral elements. The presence of masticatory forces is considered: in particular, vertical, 45° inclined, and horizontal resultant forces of 280 N are applied on five contact points of the occlusal surface. The numerical results show that the maximum stress developed in the restored tooth including a ceramic crown and subject to axial load is about 39.381 MPa, which is rather close to the 62.32 MPa stress computed for the natural tooth; stresses of about 18 MPa are localized at the roots of both crown materials. In the case of the zirconia crown, the stresses are much higher than those in the ceramic crown, except for the 45° load direction, while, for the horizontal loads, the stress peak in the zirconia crown is almost three times as large as its counterpart in the ceramic crown (i.e., 163.24 MPa vs. 56.114 MPa, respectively). Therefore, the zirconia crown exhibits higher stresses than enamel and ceramic that could increase in the case of parafunctions, such as bruxism. The clinician's choice between the two materials should be evaluated based on the patient's medical condition.

Periodontal Disease Monitoring by Raman Spectroscopy of Phosphates: New Insights into Pyrophosphate Activity.

(1) Background: The intent of this survey was to investigate the quality of the alveolar bone by revealing the different phases for calcified tissues independent of the medical history of the patient in relation to periodontal disease by means of Raman spectroscopy and then to correlate the results by suggesting a possible mechanism for the medical impairment; (2) Methods: The investigation was mainly based on Raman spectroscopy that was performed in vivo during surgery for the selected group of patients. The targeted peaks for the Raman spectra were according to the reference compounds (e.g., calcium phosphates, other phosphates); (3) Results: The variation in the intensity of the spectrum correlated to the specific bone constituents' concentrations highlights the bone quality, while some compounds (such as pyrophosphate, PPi) are strongly related to the patient's medical status, and they provide information regarding a physiological process that occurred in the calcified tissues. Moreover, bone sample fluorescence is related to the collagen (Col) content, enabling a complete evaluation of bone quality, revealing the importance of collagen matrix acting as a load-bearing element for Calcium phosphate (CaP) deposition during the complex bone mineralization process; (4) Conclusions: We highlight that Raman spectroscopy can be considered a viable investigative method for in vivo and rapid bone quality valuation through oral health monitoring.

Optimising Rehabilitation Strategies for Postpartum Elderly Gravida with In Vitro Fertilisation Conception

Optimising Rehabilitation Strategies for Postpartum Elderly Gravida with In Vitro Fertilisation Conception

Which fixation produces the best outcome for distal femoral fractures? Meta-analysis and systematic review of retrograde nailing versus distal femoral plating in 2432 patients and 33 studies.

The distal femur comprises a wide intramedullary cavity and thin cortical bone. Firm internal fixation of comminuted fractures with displacement is challenging. Although many comparative studies have reported retrograde intramedullary nailing (RIN) and distal femoral plating (DFP) as the usual fixation methods for distal femoral fractures, no clear conclusion has been reached. Therefore, a meta-analysis and systematic review of the clinical and radiological results were conducted to determine the appropriate treatment method for distal femoral fractures. A systematic search of the PubMed, Embase, Scopus, and Cochrane Library databases from their inception to December 19, 2022, was performed using predefined criteria. Studies comparing the effects of RIN and DFP were considered. The analyzed outcome measures included duration of surgery, blood loss, time to union, delayed union, nonunion, malalignment, implant failure, infection, reoperation, limb length discrepancy, range of motion, persistent anterior knee pain, knee stiffness, and functional scores. Meta-analysis of pooled data was conducted using a random-effects model to determine the standard mean difference (SMD) or odds ratio (OR) with 95% confidence intervals (CIs). Thirty-three studies with 2,432 patients were included. Compared to DFP, RIN was associated with a shorter time to fracture union (SMD, 1.83months; 95% CI - 2.76 to - 0.90; P < 0.001) and a lower incidence of postoperative infection (OR 0.54; 95% CI 0.31-0.94; P = 0.03). Pooled analysis revealed no significant differences in other outcome measures between the two treatment modalities. In distal femoral fractures, RIN had a shorter bone union time and was more resistant to infection than DFP. However, there were no significant differences in the other clinical parameters. Therefore, the characteristics, strengths, and weaknesses of RIN and DFP should be carefully identified, and appropriate treatment should be provided based on the patient's medical condition and fracture pattern.

Sound transmission through reconstructed middle ear using a full-scale model experiment

Tympanoplasty is surgical operation performed for intractable otitis media which is chronic otitis media and chronic suppurative otitis media with cholesteatoma and has multiple types depending on the patient's medical condition. This includes ossicle reconstruction by inserting reconstruction material to restore hearing, but there are some cases in which postoperative hearing performance is poor, and no expected knowledge has been obtained. There are some studies about the mechanism of sound transmission through human intact middle ear, but we have not yet obtained enough information on the mechanism of sound transmission through the reconstructed ossicles. In this study, the hypothesis that differences in sound transmission occur due to differences in the type of the reconstructed model was verified by measuring the displacement of stapes footplate with laser doppler vibrometer in a full-scale model experiment modeled on external auditory canal, tympanic membrane, and ossicles.

Superior Outcome of Bone Marrow Transplantation Using Fludarabine and Cyclophosphamide with ATG over Fludarabine and Cyclophosphamide without ATG Conditioning Regimen in Severe Aplastic Anemia

ABSTRACT Background: Matched sibling donor (MSD) allogenic hematopoietic stem cell transplantation (allo-HSCT) is the standard of care as the first line therapy for young fit patients with severe aplastic anemia (SAA). There are several conditioning regimens that have been evaluated and used for these patients. Fludarabine (Flu)/cyclophosphamide (Cy)/antithymocyte globulin (ATG) or Cy/ATG led to the best survival. The 5-year probabilities of survival after Flu/Cy/ATG, Cy/ATG, Cy ± Flu, and Busulfan /Cy were 91% (95% CI, 85-96), 91% (95% CI, 89-94), 80% (95% CI, 73-87), and 84% (95% CI, 75-91) (P = .001), (Bejanyan et al. 2019). Objective: To report the outcome of a homogeneous cohort of SAA patients who received a uniform transplantation conditioning regimen protocol (Flu/Cy/ATG) and compare it with the historical protocol (Flu/Cy) from the same transplant center for the same patients population. Methods: This study is a 10-year retrospective analysis of SAA patients who underwent MSD allo-HSCT at King Faisal Specialist Hospital &amp; Research Centre, Riyadh City, Saudi Arabia during the period from 2013 to 2022. The conditioning regimen was consistent of Fludarabine 150 mg/m 2/Cyclophosphamide 200 mg/kg/ Anti-thymocyte globulin (rabbit) 2.5 mg/kg (Flu/Cy/ATG). Graft-versus-host disease (GVHD) prophylaxis was methotrexate (MTX)/tacrolimus (FK) or methotrexate/cyclosporin (CsA). The outcome was compared with the historical published data of 82 patients with SAA received Flu/Cy conditioning regimen for MSD allo-HSCT, (El Fakih et al. 2021). Results: The study included 28 patients with SAA, 46.2% (n=12) patients were females, paroxysmal nocturnal hemoglobinuria (PNH) clone detected in 57.1% (n=16). Total body irradiation (TBI) was added to the conditioning regimen in 25% (n=7) for patients with heavily blood products transfusion pre-HSCT. A total of twenty-six patients (93%) has fully MSD, while 2 (7%) has matched unrelated donors (MUD). Bone marrow (BM) was the stem cell source in 60.7% while 28.6% received peripheral blood (PB) stem cell and 10.7 % received combined (BM/PB). There were twelve patients with donor-recipient sex mismatch. Major ABO mismatch counted for 17.9% (n=5). The median age at transplantation was 25 ±10.2 years. During the observational period, there was no graft failure (GF) and none of the patients died. At 60 days of HSCT; 61 % (n=17) patients achieved full donor whole blood (WB) chimerism, while 11 (39 %) patients had mixed chimerism. At both 180 days and 365 days of HSCT; 69.2% (n=18) patients had full donor chimerism and 30.8% (n=8) of the patients had mixed donor chimerism. Acute GVHD occurs in five cases (17.9%) and none had developed grade III or IV, notably; 80% of GVHD cases (4/5) received PB or BM/PB stem cell source. Chronic GVHD was observed in six cases (21.7%), 66% (4/6) of them had received PB or PB/BM stem cell source. The use of PB was due to either donor related reasons like recipient-donor weight discrepancy or patient's medical condition to achieve early engraftment. Hemorrhagic cystitis occurred in one case (3.6%), none had sinusoidal obstruction syndrome (SOS). CMV viremia without disease occurs in eleven patients (39 %). The median follow-up time for survivors was 34 months, the 2 years overall survival (OS) was 100%, the 2 years event free survival (EFS) defined with GF, or death was 100% compared with the previous result published (El Fakih et al., 2021) which had showen lower OS and EFS of 87.8% and 82.9% respectively with median follow-up of 100 months, Figure1&amp;2. Table-1 and table-2 summarize the comparison of patient's characteristics and outcome of both regimens (Flu/Cy vs Flu/Cy/ATG). Conclusions: The results of the present study showed better outcomes for SAA patients using Flu/Cy/ATG compared with the previous study (El Fakih et al., 2021). Early MSD allo-HSCT for SAA patients using Flu/Cy/ATG conditioning regimen is associated with a favorable outcome of excellent graft function, low rate GVHD and no GF. BM should be the stem cell source in severe aplastic anemia HSCT procedure. Key Words: Severe Aplastic Anemia, Matched Sibling Donor, Conditioning, Bone Marrow Graft, Flu/Cy/ATG.

Behavior Intervention Response Team: Piloting an Effective Means to Manage Patient- and Family-Disruptive Behaviors.

This article describes the development and implementation of a behavior intervention response team (BIRT). Pilot data indicate the successful implementation of BIRT interventions with patients and families and the positive staff response to these interventions. Patient- and family-disruptive behaviors are increasing in hospitals. Those behaviors arise from stress, financial burdens, and the mental weight of the patient's medical condition on the family. These distressed patients and their families tax an already overwhelmed staff, exacerbating the caregivers' exhaustion, depersonalization, and frustration. We recognized the need to proactively address these disruptions at our children's hospital with an interdisciplinary response. Disciplines engaged in the BIRT development included risk management, behavioral health, child life, service excellence, patient and family services, social work, and chaplaincy. Following multiple brainstorming sessions, we created a comprehensive, clear intervention strategy to engage with a disruptive patient or family. The BIRT was developed to work with both the family and their medical team to intervene at the first signs of potential disruption. With the BIRT, we were able to reduce disruptive behaviors and limit the subsequent removal of problematic individuals from the facility. Of the families who worked with the BIRT, 75.8% required no postintervention follow-up. The development of a BIRT can help head off disruptive behaviors and improve family-medical team relationships to support the highest quality and safest healthcare.

Individualized Periprocedural and Intraprocedural Management for Coil Embolization of Unruptured Cerebral Aneurysm in a Patient with Severe Thrombocytopenia due to Liver Cirrhosis

A female patient in her early 60's with advanced liver cirrhosis and thrombocytopenia having a platelet count under 30,000/µL, visited an outpatient clinic. Computed tomography angiography revealed an unruptured aneurysm on the left middle cerebral artery bifurcation with 6.0 mm of maximal diameter. Endovascular coiling was planned, considering the patient's medical condition. Eight pints of platelet concentrate were transfused 6 hours before the procedure, and a platelet count of 57,000/ µL was achieved 3 hours before the procedure. No antiplatelet premedication and intraprocedural heparin was administered. A bail-out use of intra- or postoperative Tirofiban (Aggrastat®) was prepared for inadvertent thromboembolic events. The aneurysm was successfully occluded with no procedure-related event. The patient’s hospital course was uneventful, and she was discharged without complications. Despite the potential hemorrhagic risk caused by hemostatic failure in patients with cirrhosis, successful endovascular coiling can be performed with highly individualized management.
