The characteristics of CALR mutations in myeloproliferative neoplasms: a clinical experience from a tertiary care center in Qatar and a literature review.

BACKGROUND: Myeloproliferative neoplasms (MPNs) are hematological disorders characterized by abnormal production of myeloid cells due to genetic mutations. Since 2013, researchers have identified somatic mutations in the Calreticulin (CALR) gene, primarily insertions or deletions, in two Philadelphia chromosome-negative MPNs; essential thrombocytosis (ET) and primary myelofibrosis (PMF), and occasionally in chronic myelomonocytic leukemia (CMML). This study aims to identify the various types of CALR mutations and their impact on CALR-positive MPN patients' clinical manifestations and outcomes. METHODS: A single-center retrospective study was conducted. The data was collected from pre-existing records. The study was carried out on Philadelphia-negative MPN patients who were being followed up on at the NCCCR (National Center for Cancer Care and Research) to assess the clinical manifestation and outcome of disease treatment. All patients included, were followed in our center between January 1, 2008, and November 20, 2021. RESULTS: A total of 50 patients with CALR-positive MPN were reviewed with a median follow-up of three years (1-11). This cohort included 31 (62%) patients with ET, 10 (20%) patients with PMF, and 9 (18%) patients with prefibrotic myelofibrosis (pre-MF). The study involved 38 (76%) male and 12 (24%) female patients. There were 16 (32%) patients diagnosed before the age of 40, 24 (48%) patients diagnosed between the ages of 40 and 60; and 10 (20%) patients diagnosed after the age of 60. Molecular analysis showed 24 (48%) patients with CALR type 1, 21 (42%) patients with CALR type 2, and 5 (10%) patients with none Type 1, none Type 2 CALR mutations. Two patients have double mutations; 1(2%) with none Type 1, none Type 2 CALR and JAK2 mutations, and 1(2%) with CALR type 1 and MPL mutations. The thrombotic events were 3 (6%) venous thromboembolisms, 3 (6%) abdominal veins thromboses, 2 (4%) strokes, and 4 (8%) ischemic cardiac events. Only 4 (8%) patients progressed to Myelofibrosis and were carrying CALR 1 mutations, and 1 (2%) patient progressed to AML with CALR 2 mutation. CONCLUSION: The data shows a significant rise in CALR-positive MPN diagnoses in younger people, emphasizing the need for a better assessment tool to improve disease management and reduce complications.

Exploring knowledge, attitudes and practice toward medication therapy management services among pharmacists in Yemen.

Medication therapy management (MTM) refers to the activities provided by pharmacists that patients recognize as evidence of care being provided. It encompasses the services that patients value and consider valuable. Many developing nations like Yemen have had poor implementation of MTM services. Thus, this research assessed the Knowledge, Attitudes, and Practices (KAP) of Yemen pharmacists regarding MTM. We conducted a cross-sectional study using a self-administered questionnaire among pharmacists in Sana'a, Yemen. They were recruited through convenience sampling. The alpha level of 0.05 was used to determine statistical significance. Four hundred and sixty-one (461) pharmacists completed the questionnaire. About 70% were working in community pharmacies and 57.3% had (1-5) years of experience in pharmacy practice. The younger pharmacists had a higher level of knowledge than pharmacists with older age with median and IQR of 1.2(1.2-1.4) and 1.2(1-1.4) respectively (p < 0.001). Yemen pharmacists have positive attitudes toward MTM indicating a moderated level of attitudes with a median and IQR of 3.8(3.5-4). Hospital pharmacists expressed more positive attitudes toward MTM (P < 0.001) than pharmacists from other areas of practice. Only 11% of sampled pharmacists frequently offered MTM services. The top MTM service reported by Yemen pharmacists was "Performing or obtaining necessary assessments of the patient's health status". However, "Formulating a medication treatment plan" received the least provided MTM service among Yemen pharmacists. Even though MTM services are not commonly utilized in pharmacy practice, Yemeni pharmacists have positive attitudes concerning MTM. Efforts are needed to enhance their MTM knowledge and the value of providing MTM services as well as to develop a culture of continuing pharmacy education about MTM among pharmacists.

The Impact of Pharmacist Medication Reviews on Geriatric Patients: A Scoping Review.

Medication review is an intervention with the potential to reduce drug-related problems (DRPs) in the elderly. This study aimed to determine the effect of pharmacists' medication reviews on geriatric patients. This study accessed two online databases, MEDLINE Complete and Scopus, and examined all studies published in English between 2019 and 2023, except for reviews. The studies included (1) participants over 65 years of age and (2) medication reviews conducted by pharmacists. The titles, abstracts, and full texts were reviewed for data extraction to determine whether the studies satisfied the inclusion and exclusion criteria. Forty-four of the initial 709 articles were included in this study. The articles included discussions on the incidence rates of DRPs and potentially inappropriate medications (PIMs) (n=21), hospitalization (n=14), medication adherence (n=9), quality of life (QoL) (n=8), and falls (n=7). Pharmacist medication reviews were associated with a reduced incidence of DRPs and PIMs, and improved adherence to medications. Patients' overall QoL is also increasing. However, pharmacist medication reviews were not strongly associated with decreased hospitalization or falls. A pharmacist's medication review may be a feasible intervention for reducing the incidence rates of DRPs and PIMs, regardless of whether it is performed as a sole intervention or supplemented with other interventions. The intervention was also effective in increasing medication adherence and QoL.

Assessing feasibility of conducting medication review with follow-up among older adults at community pharmacy: a pilot randomised controlled trial.

BACKGROUND: Medication review with follow-up is essential for optimising medication utilisation among the older adult population in primary healthcare. AIM: This study aimed to evaluate the feasibility of implementing medication reviews with follow-up for older adults in community pharmacies and examined potential outcomes on medication use. METHOD: A pilot randomised controlled trial was conducted with 4 cluster-randomised community pharmacies to assess the feasibility of the intervention. Two community pharmacies served as intervention and control groups. Both groups recruited older adults over 60 who were followed over 6 months. The translated Medication use Questionnaire (MedUseQ) was administered at baseline and 6 months for both groups. The outcomes were to assess the feasibility of conducting medication review with follow-up and the probable medication use outcomes from the intervention. RESULTS: The intervention and control groups comprised 14 and 13 older adults. A total of 35 recommendations were made by pharmacists in the intervention group and 8 in the control group. MedUseQ was easily administered, providing some evidence the feasibility of the intervention. However, there were feasibility challenges such as a lack of pharmacists, collaborative practice, difficulties with the tool language, time constraints, and limited funds. Questionnaire results provided a signal of improvement in medication administration, adherence, and polypharmacy among intervention participants. The incidence of drug related problems was significantly higher in the control group (median = 1) after 6 months, U = 15, z = - 2.98, p = 0.01. CONCLUSION: Medication review with follow-up is potentialy practical in community pharmacies, but there are feasibility issues. While these challenges can be addressed, it is essential to study larger sample sizes to establish more robust evidence regarding outcomes. CLINICAL TRIAL REGISTRY: ClinicalTrials.Gov NCT05297461.

The Impact of Clinical Pharmacist Diabetes Education on Medication Adherence in Patients with Type 2 Diabetes Mellitus: An Interventional Study from Khartoum, Sudan.

BACKGROUND: Continuous therapeutic care with good medication adherence is the cornerstone of management of all chronic diseases including diabetes. This study aimed to evaluate the impact of clinical pharmacist intervention on the medication adherence in individuals with type 2 diabetes (T2DM). METHODS: This was a randomized, double-blind, controlled trial conducted at a diabetes clinic located at Omdurman Military Hospital, Sudan. Individuals with T2DM attending the diabetes clinic within 1 year were selected. The sample size was 364 participants (182 control and 182 interventional group). We used a pre-structured standardized questionnaire and checklist to collect the data. Data were analyzed by using the Statistical Package for the Social Sciences (SPSS) (version 28). RESULTS: Majority, 76.4% (n = 278) were females, and they consisted of 80.8% (n = 147) of the interventional group and 72% of the controls. The mean age of the interventional group was 54.5 (±10) years; 31.9% (n = 58) of the interventional group had diabetes for 6-10 years, compared with 26.4% (n = 48) of the control group. Among the control group, the mean adherence score was 6.8 (±1.7) at baseline and it was 6.7 (±1.6) at the end of the study (p < 0.001), while in the interventional group, the mean adherence score was 6.8 (±1.7) at baseline and it was 7.4 (±1.5) at the end of the study (p < 0.001). CONCLUSION: Adherence score among the intervention group was increased significantly from baseline to the end of the study when compared to the control group.
