Risk scores predicting disease progression in early-stage CLL: Comparative analysis and usefulness of IGHV subset #2 to improve their accuracy.

BACKGROUND: Overall, the prognosis of patients with chronic lymphocytic leukemia (CLL) in the early phase of the disease (Rai 0, Binet A) is favorable; some patients never require therapy. However, some patients require intervention shortly after diagnosis. In the past decade, several risk scores (RS) have been developed to predict disease progression, yet some patients are misclassified. On the other hand, IGHV subset 2 (IGHV2) predicts poor outcomes. METHODS: A retrospective and multicentric study was conducted to compare the accuracy of five different RS (IPS-E, CR0, AIPS-E, CLL-IPI, and Barcelona-Brno) to predict disease progression in 781 stage A previously untreated patients with CLL. As an exploratory analysis, it was further investigated whether the inclusion of the IGHV2 as a poor prognostic parameter improved the accuracy of RS. RESULTS: All the scores identified a similar group of patients with CLL in early stage with low-, intermediate-, and high-risk progression. Discrimination was high and similar in all RS (c-index = 0.74-0.79, area under the curve = 0.7-0.75), as well as calibration (p = .98) and parsimony, although CLL-IPI showed the best results (Akaike information criterion = 441). A total of 34.4% of patients were categorized within the same RS and concordance was at least moderate between RS. CONCLUSION: Moreover, the results suggest that IGHV2 may improve the accuracy of RS.

Philadelphia-negative chronic myeloproliferative neoplasm follow-up: when the phone rings. Changes during the COVID-19 pandemic and patient satisfaction. Experience in 30 health centers in Spain.

The SARS-CoV-2 pandemic has favored the expansion of telemedicine. Philadelphia-negative chronic myeloproliferative neoplasms (Ph-MPN) might be good candidates for virtual follow-up. In this study, we aimed to analyze the follow-up of patients with Ph-MPN in Spain during COVID-19, its effectiveness, and acceptance among patients. We present a multicenter retrospective study from 30 centers. Five hundred forty-one patients were included with a median age of 67 years (yr). With a median follow-up of 19 months, 4410 appointments were recorded. The median of visits per patient was 7 and median periodicity was 2.7 months; significantly more visits and a higher frequency of them were registered in myelofibrosis (MF) patients. 60.1% of visits were in-person, 39.5% were by telephone, and 0.3% were videocall visits, with a predominance of telephone visits for essential thrombocythemia (ET) and polycythemia vera (PV) patients over MF, as well as for younger patients (< 50 yr). The proportion of phone visits significantly decreased after the first semester of the pandemic. Pharmacological modifications were performed only in 25.7% of the visits, and, considering overall management, ET patients needed fewer global treatment changes. Telephone contact effectiveness reached 90% and only 5.4% required a complementary in-person appointment. Although 56.2% of the cohort preferred in-person visits, 90.5% of our patients claimed to be satisfied with follow-up during the pandemic, with an 83% of positive comments. In view of our results, telemedicine has proven effective and efficient, and might continue to play a complementary role in Ph-MPN patients' follow-up.

A second administration of glucarpidase in a different cycle of high-dose methotrexate: Is it safe and effective in adults?

INTRODUCTION: Methotrexate intoxication following high-dose methotrexate-induced acute kidney injury is a life-threatening complication. Glucarpidase can quickly reduce extracellular methotrexate to safe levels, but the effectiveness and safety of its use in different episodes of nephrotoxicity remain an unknown area. CASE REPORT: A 30-year-old male diagnosed with acute lymphoblastic T-cell lymphoma received methotrexate 5 g/m2 intravenous (IV) as part of the first consolidation cycle. On Consolidation 3, he restarted methotrexate at a dose of 3 g/m2 IV showing slow methotrexate elimination, associated myelosuppression, and hepatic toxicity. Glucarpidase was administered (total dose of 2000 International Units (IU)). No adverse events were observed, and his renal function returned to normal. One hundred and six days later, he was diagnosed with leptomeningeal and cerebellar relapse and treatment with methotrexate 3,5 g/m2 IV day 1 and cytosine arabinoside (Ara-C) 2 g/m2 IV twice per day days 1, 3, and 5 was started. At 36 h from methotrexate infusion, serum creatinine increased up to 1.89 mg/dL and methotrexate concentration was 100 µmol/L.Management and Outcome: Ara-C was suspended, and a second administration of glucarpidase (2000 IU) was dispensed. No adverse events were noticed, methotrexate levels decreased and renal function progressively improved, recovering completely three weeks later. DISCUSSION: The effectiveness and safety of the use of glucarpidase in different episodes of nephrotoxicity remain an unknown area, and the rate and consequences of antiglucarpidase antibody formation remain poorly understood. This case report is, to our knowledge, the first case of a second administration of glucarpidase in a different cycle of high-dose methotrexate in an adult patient.

Predicting Survival after Allogeneic Hematopoietic Cell Transplantation in Myelofibrosis: Performance of the Myelofibrosis Transplant Scoring System (MTSS) and Development of a New Prognostic Model.

Accurate prognostic tools are crucial to assess the risk/benefit ratio of allogeneic hematopoietic cell transplantation (allo-HCT) in patients with myelofibrosis (MF). We aimed to evaluate the performance of the Myelofibrosis Transplant Scoring System (MTSS) and identify risk factors for survival in a multicenter series of 197 patients with MF undergoing allo-HCT. After a median follow-up of 3.1 years, 47% of patients had died, and the estimated 5-year survival rate was 51%. Projected 5-year risk of nonrelapse mortality and relapse incidence was 30% and 20%, respectively. Factors independently associated with increased mortality were a hematopoietic cell transplantation-specific comorbidity index (HCT-CI) ≥3 and receiving a graft from an HLA-mismatched unrelated donor or cord blood, whereas post-transplant cyclophosphamide (PT-Cy) was associated with improved survival. Donor type was the only parameter included in the MTSS model with independent prognostic value for survival. According to the MTSS, 3-year survival was 62%, 66%, 37%, and 17% for low-, intermediate-, high-, and very high-risk groups, respectively. By pooling together the low- and intermediate-risk groups, as well as the high- and very high-risk groups, we pinpointed 2 categories: standard risk and high risk (25% of the series). Three-year survival was 62% in standard-risk and 25% in high-risk categories (P < .001). We derived a risk score based on the 3 independent risk factors for survival in our series (donor type, HCT-CI, and PT-Cy). The corresponding 5-year survival for the low-, intermediate-, and high-risk categories was 79%, 55%, and 32%, respectively (P < .001). In conclusion, the MTSS model failed to clearly delineate 4 prognostic groups in our series but may still be useful to identify a subset of patients with poor outcome. We provide a simple prognostic scoring system for risk/benefit considerations before transplantation in patients with MF.

Mirtazapine reduces the expression of cocaine-induced locomotor sensitization in male and female Wistar rats.

BACKGROUND: Epidemiological studies have described that women are more vulnerable to the reinforcing effects of cocaine. In animals, the findings are similar: female rats show higher levels of cocaine self-administration and increased cocaine-induced locomotor activity. In contrast, women with depression respond better to treatment with antidepressants, however their therapeutic response to tetracyclic antidepressants is lower. Several studies have shown that mirtazapine-a tetracyclic antidepressant-decreases the behavioral effects of cocaine in male rats. The objective of this study was to evaluate the efficacy of daily dosing of mirtazapine on cocaine-induced locomotor activity and sensitization in naive female rats compared to male rats. METHODS: Male and female Wistar rats were daily dosed with 10 mg/kg of cocaine. During extinction, cocaine was withdrawn and the groups received daily mirtazapine (30 mg/kg, i.p.) or saline. Tamoxifen was administered during the antagonism phase. After each administration, locomotor activity for each animal was recorded for 30 min in transparent Plexiglass activity chambers. RESULTS: In this study, a higher cocaine locomotor response was found in females than in males and the mirtazapine was equally effective in decreasing cocaine-induced locomotor activity and the expression of locomotor sensitization in male and female rats. In addition, co-administration of mirtazapine and tamoxifen enhanced the efficacy of mirtazapine in female rats. CONCLUSION: The results suggest that mirtazapine may be considered an effective therapeutic option for the treatment of cocaine use disorder in men and women.

Drug-to-drug interactions of tyrosine kinase inhibitors in chronic myeloid leukemia patients. Is it a real problem?

With tyrosine kinase inhibitors (TKI), chronic myeloid leukemia (CML) patients are achieving similar rates of survival to the general population and some treatment aspects such as adherence and drug-to-drug interactions (DDI) are becoming increasingly important. Our aim was to investigate the frequency and real clinical consequences of DDI between TKI and concurrent medications in CML. We performed a retrospective multicenter study including 105 patients receiving 134 TKI treatments. Sixty-three patients (60%) had at least one potential DDI. The mean number of concomitant medications was 4.8 (0-19). The mean number of DDI by TKI treatment was 1.2 (0-8); it increased with the number of concomitant medications and age in a significant manner. A total of 159 DDI were detected, involving 55 different drugs. The most common drug classes involved were proton pump inhibitors, statins, and antidepressants. A DDI-related clinical effect (toxicity and/or lack of efficacy) was suspected during the common course of patient follow-up in only five patients (4.7%). This number increased to 20% when data were centrally reviewed. Most of the adverse events (AE) attributed to DDIs were mild. The most common were diarrhea, vomiting, edema, cramps, and transaminitis. Nilotinib and dasatinib showed a tendency towards a higher risk of DDI compared with imatinib. There were no significant differences in AE frequency or in treatment response between patients with or without DDI. Due to their frequency, and their potential to cause clinically relevant effects, DDI are an important aspect of CML management.

Imatinib dose reduction in patients with chronic myeloid leukemia in sustained deep molecular response.

To determine whether a lower imatinib dose could minimize toxicity while maintaining the molecular response (MR), imatinib dose was reduced to 300 mg daily in 43 patients with chronic myeloid leukemia (CML) in sustained deep molecular response to first-line imatinib 400 mg daily. At the time of dose reduction, median duration of the deep response was 4.1 (interquartile range (IQR) 2.2-5.9) years; molecular response was MR4, MR4.5, and MR5 of the international scale in 6, 28, and 9 patients, respectively. Toxicity grade was 1, 2, and 3 in 28, 8, and 1 patients, respectively; 6 patients underwent dose reduction without having side effects. With a median of 1.6 (IQR 0.7-3.2) years on imatinib 300 mg daily, only one patient lost the deep molecular response to MR3. At the last follow-up, response was MR3, MR4, MR4.5, and MR5 in 1, 3, 9, and 30 patients, respectively. Toxicity improvement was observed in 23 (62.2 %) of the 37 patients with side effects, decreasing to grade 0 in 20 of them. All but one anemic patients improved (p = 0.01), the median Hb increase in this subgroup of patients being 1 g/dL. In CML patients with sustained deep response to the standard imatinib dose, reducing to 300 mg daily significantly improves tolerability and preserves efficacy.

Severe liver toxicity in a chronic myeloid leukemia patient probably induced by a drug interaction between imatinib and sertraline.

Our objective is to describe a chronic myeloid leukemia patient with a severe liver toxicity likely due to a drug-drug interaction between imatinib and sertraline. The patient started treatment with sertraline three months after starting imatinib. From the beginning of sertraline treatment, the patient developed vomiting, and five weeks later she developed a severe hepatic failure and was admitted to the hospital. The Naranjo nomogram showed a probable correlation between this adverse effect and the interaction between imatinib and sertraline. This interaction is extremely rare and the mechanism of action is not clear; it could be a mix of pharmacokinetic and pharmacodynamic processes. To our knowledge, this is the first case in medical literature of a severe liver toxicity due to an interaction between imatinib and sertraline. This interaction is also not described in the main secondary data sources, such as Lexicomp® and Micromedex®. However, due to the severity of this event, the hepatic function should be carefully monitored in patients treated with imatinib and sertraline.

Recommendations on the clinical use of bendamustine in lymphoproliferative syndromes and multiple myeloma.

Bendamustine is an increasingly used hybrid alkylating agent that is active in lymphoid neoplasias via a novel mechanism of action. There are some pending questions about its use in clinical practice because of its developmental features. A consensus panel of several leading Spanish hematologists with broad experience in the clinical use of bendamustine has established recommendations for the management and treatment of hematological patients with bendamustine based on available clinical data and the experience of the participants. These recommendations address the dose and treatment regimen for different clinical indications, the management of toxicity, and support therapy. This article contains the conclusions of this consensus panel, which are intended to serve as guidelines for the use of bendamustine.

Multivariate time-dependent comparison of the impact of lenalidomide in lower-risk myelodysplastic syndromes with chromosome 5q deletion.

The impact of lenalidomide treatment on long-term outcomes of patients with lower risk myelodysplastic syndromes (MDS) and chromosome 5q deletion (del(5q)) is unclear. This study used time-dependent multivariate methodology to analyse the influence of lenalidomide therapy on overall survival (OS) and acute myeloblastic leukaemia (AML) progression in 215 patients with International Prognostic Scoring System (IPSS) low or intermediate-1 risk and del(5q). There were significant differences in several relevant characteristics at presentation between patients receiving (n = 86) or not receiving lenalidomide (n = 129). The 5-year time-dependent probabilities of OS and progression to AML were 62% and 31% for patients receiving lenalidomide and 42% and 25% for patients not receiving lenalidomide; differences were not statistically significant in multivariate analysis that included all variables independently associated with those outcomes (OS, P = 0·45; risk of AML, P = 0·31, respectively). Achievement of RBC transfusion independency (P = 0·069) or cytogenetic response (P = 0·021) after lenalidomide was associated with longer OS in multivariate analysis. These data clearly show that response to lenalidomide results in a substantial clinical benefit in lower risk MDS patients with del(5q). Lenalidomide treatment does not appear to increase AML risk in this population of patients.

Do chronic myeloid leukemia patients with late "warning" responses benefit from "watch and wait" or switching therapy to a second generation tyrosine kinase inhibitor?

In the latest recommendations for the management of chronic-phase chronic myeloid leukemia suboptimal responses have been reclassified as "warning responses." In contrast to previous recommendations current guidance advises close monitoring without changing therapy. We have identified 198 patients treated with first-line imatinib, with a warning response after 12 months of treatment (patients with a complete cytogenetic response but no major molecular response [MMR]). One hundred and forty-six patients remained on imatinib, while 52 patients changed treatment to a second generation tyrosine kinase inhibitor (2GTKI). Changing therapy did not correlate with an increase in overall survival or progression-free survival. Nevertheless, a significant improvement was observed in the probability of a MMR: 24% vs. 42% by 12 months and 43% vs. 64% by 24 months (P = 0.002); as well as the probability of achieving a deep molecular responses (MR(4.5) ): 1% vs. 17% and 7% vs. 23% by 12 and 24 months, respectively (P = <0.001) .The treatment change to 2GTKI remained safe; however, we have observed a 19% of treatment discontinuation due to side effects. We have observed an improvement of molecular responses after changing treatment to 2GTKI in patients with late suboptimal response treated with imatinib first line. However, these benefits were not correlated with an improvement of progression free survival or overall survival.

Janus kinase inhibitor ruxolitinib in combination with nilotinib and prednisone in patients with myelofibrosis (RuNiC study): A phase Ib, multicenter study.

This phase Ib, non-randomized, open-label study evaluates the safety and tolerability of ruxolitinib in combination with nilotinib and prednisone in patients with naïve or ruxolitinib-resistant myelofibrosis (MF). A total of 15 patients with primary or secondary MF received the study treatment; 13 patients had received prior ruxolitinib treatment (86.7%). Eight patients completed seven cycles (53.3%) and six patients completed twelve cycles of treatment (40%). All the patients experienced at least one adverse event (AE) during the study (the most common AEs were hyperglycemia, asthenia, and thrombocytopenia), and 14 patients registered at least one treatment-related AE (the most common treatment-related AEs were hyperglycemia (22.2%; three grade 3 cases). Five treatment-related serious AEs (SAEs) were reported in two patients (13.3%). No deaths were registered throughout the study. No dose-limiting toxicity was observed. Four out of fifteen (27%) patients experienced a 100% spleen size reduction at Cycle 7, and two additional patients achieved a >50% spleen size reduction, representing an overall response rate of 40% at Cycle 7. In conclusion, the tolerability of this combination was acceptable, and hyperglycemia was the most frequent treatment-related AE. Ruxolitinib in combination with nilotinib and prednisone showed relevant clinical activity in patients with MF. This trial was registered with EudraCT Number 2016-005214-21.

CNL and aCML should be considered as a single entity based on molecular profiles and outcomes.

Chronic neutrophilic leukemia (CNL) and atypical chronic myeloid leukemia (aCML) are rare myeloid disorders that are challenging with regard to diagnosis and clinical management. To study the similarities and differences between these disorders, we undertook a multicenter international study of one of the largest case series (CNL, n = 24; aCML, n = 37 cases, respectively), focusing on the clinical and mutational profiles (n = 53 with molecular data) of these diseases. We found no differences in clinical presentations or outcomes of both entities. As previously described, both CNL and aCML share a complex mutational profile with mutations in genes involved in epigenetic regulation, splicing, and signaling pathways. Apart from CSF3R, only EZH2 and TET2 were differentially mutated between them. The molecular profiles support the notion of CNL and aCML being a continuum of the same disease that may fit best within the myelodysplastic/myeloproliferative neoplasms. We identified 4 high-risk mutated genes, specifically CEBPA (ß = 2.26, hazard ratio [HR] = 9.54, P = .003), EZH2 (ß = 1.12, HR = 3.062, P = .009), NRAS (ß = 1.29, HR = 3.63, P = .048), and U2AF1 (ß = 1.75, HR = 5.74, P = .013) using multivariate analysis. Our findings underscore the relevance of molecular-risk classification in CNL/aCML as well as the importance of CSF3R mutations in these diseases.

A case report of a novel mutation in lamin A/C gene related with risk of sudden death.

Background: Lamin A/C-associated heart disease is a group of clinical entities characterized by a mutation in the LMNA gene. Multiple cardiac phenotypes have been described, including a higher risk of sudden death. Case summary: A 23-year-old asymptomatic patient with an extensive history of heart disease in the family consulted the clinic. He had a genetic test performed when he was born revealing a new frameshift mutation in the LMNA gene. Numerous cardiac function tests were ordered, which initially were normal. After a year of follow-up, Holter monitoring was positive for episodes of nonsustained ventricular tachycardia (NSVT). Because of the risk factors and higher likelihood of sudden death, a decision was made to offer an implantable cardiac defibrillator (ICD), which was performed without complications. The patient continues the follow-up with cardiology and electrophysiology consisting of yearly cardiac imaging and device recordings. Discussion: Lamins are nuclear proteins involved in various cellular processes in myocardial cells. Therefore, mutations are associated with wide phenotypic alterations. The mutation described here was not previously reported in the literature. In the face of an undescribed mutation, the decision to use an ICD for primary prevention of sudden death is challenging. Because of the episodes of NSVT and a higher likelihood of risk of sudden death due to male sex and first-degree atrioventricular block, the decision to use an ICD was made for this patient, with no complications.

A smartphone app to improve the safety of patients undergoing treatment with oral antineoplastic agents: 4 years of experience in a university hospital.

Objective: This study aims to analyze the impact of the eOncosalud app on the management and follow-up of adverse effects (AE) in patients receiving oral antineoplastic agents. Material and methods: We performed an observational, prospective study of cancer outpatients treated with oral antineoplastic agents (OAA), monitored by the eOncosalud app between August 2017 and October 2021. Safety variables were collected from eOncosalud: the number of AE; severity of the AE according to CTCAE, version 4.03; timelapse from app installation to first recorded AE; automatic recommendations issued; and the patient's acceptance of the recommendations made. To assess the impact of the recommendations generated by the algorithm, we calculated the positive predictive value (PPV) as the number of recommendations accepted out of the total number of recommendations generated. Safety-related patient messages were also analyzed (AE, drug-drug interactions, drug administration). Result: The app was downloaded and used by 186 patients (58.0% women), with a mean age of 59.0 years. A total of 1,368 AE were recorded, the most frequent being fatigue (19.37%), diarrhea (18.20%), and skin changes (9.21%). Regarding the recommendations issued by the app algorithm, 102 patients received 344 information brochures, 39 patients received 51 recommendations for supportive care to control AE, 60 patients received 240 recommendations to visit their primary care doctor, 14 patients received 16 recommendations to contact their specialist pharmacist or oncologist-hematologist, and 34 patients received 73 recommendations to go to the emergency room. The suggestion to go to the emergency room and contact the specialist pharmacist or oncologist-hematologist had a PPV of 0.51 and 0.35, respectively. Half of the patients (50.4%) used the messaging module. A total of 1,668 messages were sent. Of these, 47.8% were related to treatment safety: AE, 22.7%; drug-drug interactions, 20.6%; drug administration, 3.6%; and missing a dose, 1.0%. Conclusions: The eOncosalud app enables close, real-time monitoring of patients treated with OAA. The automatic recommendations through the app's algorithm have optimized available healthcare resources. The app facilitated early detection of AE, thus enabling patients themselves to improve the safety of their treatment.

Abbreviated magnetic resonance imaging in breast cancer: A systematic review of literature.

BACKGROUND: : magnetic resonance imaging (MRI) has been increasingly used to study breast cancer for screening high-risk cases, pre-operative staging, and problem-solving because of its high sensitivity. However, its cost-effectiveness is still debated. Thus, the concept of abbreviated MRI (ABB-MRI) protocols was proposed as a possible solution for reducing MRI costs. PURPOSE: : to investigate the role of the abbreviated MRI protocols in detecting and staging breast cancer. METHODS: : a systematic search of the literature was carried out in the bibliographic databases: Scopus, PubMed, Medline, and Science Direct. RESULTS: : forty-one articles were included, which described results of the assessment of fifty-three abbreviated protocols for screening, staging, recurrence assessing, and problem-solving or clarification. CONCLUSIONS: : the use of ABB-MRI protocols allows reducing the acquisition and reading times, maintaining a high concordance with the final interpretation, in comparison to a complete protocol. However, larger prospective and multicentre trials are necessary to validate the performance in specific clinical environments.

Error Detection and Cost Savings With an Image-Based Workflow Management System Connected to a Computerized Prescription Order Entry Program for Antineoplastic Compounding.

OBJECTIVE: The aim of the study was to analyze both the prevalence of errors with the implementation of an image-based workflow management system during the antineoplastic compounding process, and the estimated costs associated with the negative clinical outcome if the errors had not been intercepted. METHODS: Three months after the implementation of Phocus Rx system at a hospital pharmacy department, the identification, classification (type, preparation stage, and cause), and potential severity degree (from negligible to catastrophic) of the errors intercepted were determined. The probability of an error causing an adverse event if it had reached the patient (from nil [0] to high [0.6]) and its consequences was estimated by a team of clinical pharmacists and physicians. Cost-effectiveness analysis from the hospital's perspective was performed. RESULTS: Overall, 9872 antineoplastic medications were prepared using Phocus Rx. The total compounding error rate was 0.8% (n = 78, 56 [69.2%] were related to incorrect dose, 20 [28.2%] to incorrect drug preparation or conditioning technique, and 2 [2.6%] were wrong drugs). Approximately 70% of the detected errors were classified as undetectable via the previous verification practice, with 11.55% judged to be potentially severe (n = 9) and 51.3% moderate (n = 29). Likelihood of occurrence of an adverse event was medium (0.4) to high (0.6) for 37.2% of the errors. Estimated cost ratio and return on investment were €4.21 and 321%, respectively. CONCLUSIONS: The implementation of Phocus Rx prevented antineoplastic preparation errors that would have reached the patient otherwise. In addition, acquisition of this technology was estimated to be cost-effective.

Clinical utility of targeted next-generation sequencing for the diagnosis of myeloid neoplasms with germline predisposition.

Myeloid neoplasms (MN) with germline predisposition (MNGP) are likely to be more common than currently appreciated. Many of the genes involved in MNGP are also recurrently mutated in sporadic MN. Therefore, routine analysis of gene panels by next-generation sequencing provides an effective approach to detect germline variants with clinical significance in patients with hematological malignancies. Gene panel sequencing was performed in 88 consecutive and five nonconsecutive patients with MN diagnosis. Disease-causing germline mutations in CEBPα, ASXL1, TP53, MPL, GATA2, DDX41, and ETV6 genes were identified in nine patients. Six out of the nine patients with germline variants had a strong family history. These patients presented great heterogeneity in the age of diagnosis and phenotypic characteristics. In our study, there were families in which all the affected members presented the same subtype of disease, whereas members of other families presented various disease phenotypes. This intrafamiliar heterogeneity suggests that the acquisition of particular somatic variants may drive the evolution of the disease. This approach enabled high-throughput detection of MNGP in patients with MN diagnosis, which is of great relevance for both the patients themselves and the asymptomatic mutation carriers within the family. It is crucial to make a proper diagnosis of these patients to provide them with the most suitable treatment, follow-up, and genetic counseling.
