The Impact of Cancer Relapse and Poor Patient Outcomes on Health Care Providers Practicing in the Oncology Field.

INTRODUCTION: Devastating cancer-related events are not uncommon, and these events have weakened communication performance and induced stress among health care providers (HCPs), particularly physicians. This study aimed to investigate the perspective of HCPs emotionally affected by poor clinical outcomes due to the failure of cancer therapy. METHODS: A cross-sectional, online survey was conducted over 3 months among HCPs practicing in the field of oncology in Saudi Arabia, comprising physicians, pharmacists, and nurses. Data were analyzed using Statistical Package for Social Sciences version 26.0. A P-value <.05 was considered statistically significant. RESULTS: This study demonstrated a positive correlation between HCPs' length of experience and emotional impact of treatment failure, albeit this was not statistically significant (P = .071). Analysis of their perspective toward failure of cancer therapies revealed a significant impact of occupation and sex (P = .014 and P = .047, respectively). Moreover, occupation played a significant role in shaping the viewpoint of HCPs toward the need for conducing further research to test the appropriateness of treatment protocols on local patients (P = .022). Despite the emotional responses of HCPs to suboptimal clinical outcomes, factors such as work burnout, lack of concentration and patience, work or personal problems, and under appreciation were frequently identified as triggers of such outcomes. CONCLUSION: Our results revealed that poor clinical outcomes observed among cancer patients are emotional triggers for HCPs practicing in the oncology field. The emotional response is often perceived negatively, and can potentially lead to a decline in the quality of care provided to these patients.

The body weight heritability and the effect of non-genetic factors on the body measurement traits in Qinchuan cattle.

This study aimed to understand the influence of the non-genetic factors that include breeding year, season, and sex of growth and development traits of Qinchuan cattle and to estimate the heritability of body weight at different growth stages. The Qinchuan cattle measurement records were by the Experiment farm of the National Beef Cattle Improvement Center (Yangling, China) from 2000 to 2017. SPSS and R software were used to analyze the influence of non-genetic factors on body size traits that include body weight (BW), withers height (WH), hip height (HH), body length (BL), chest circumference (CC), abdominal girth (AG), and calf girth (CG), at birth, 6, 12, 18, and 24 months of age. Meanwhile, the single-trait animal model of DMU software was used to estimate the variance component and the heritability of body weight. The results of GLM analysis showed as follows: sex, birth year, and birth season had effects on the body size traits of Qinchuan cattle at different growth stages. Respectively, the heritability of body weight at birth, 6, 12, 18, and 24 months of age were 0.43, 0.32, 0.37, 0.32, and 0.38.

The impact of Hydroxyurea on the rates of Vaso-occlusive crises in patients with sickle cell disease in Saudi Arabia: a single-center study.

BACKGROUND: Vaso-occlusive crises (VOCs) are acute and common painful complication of sickle cell disease (SCD), and are the main reason behind the frequent emergency department visits among SCD patients. Hydroxyurea (HU) is an old and commonly used medication that demonstrated its effectiveness in reducing the risk of VOCs and the incidence of hospitalization. Although multiple studies have examined the impact of HU on the rates of VOCs, few have explored its effectiveness among SCD patients in Saudi Arabia. METHODS: This was a single-center retrospective cohort study in which the electronic medical records of patients with SCD who have not had any previous exposure to HU prior to the initiation of HU treatment for ≥12 months were recruited. Paired t-test was conducted to examine the difference in the rates of VOCs, and levels of hemoglobin (Hgb), hematocrit (HCT), and platelet counts (PLT Ct) prior to the initiation of HU therapy and 12 months later. Multiple linear regression was conducted to examine whether age, gender, use of opioid analgesics, Hgb, HCT, and PLT Ct levels predict higher or lower rates of VOCs. RESULTS: One hundred and fifty-six patients met the inclusion criteria and were included in the analysis. About 51% of the patients were males, and their mean age was 12.69 years. The mean HU dosage was 16.52 mg/kg/day, and the mean reduction in the rate of VOCs was 1.36 events per patient per year (95% CI [1.03-1.70], p < 0.0001) after the initiation of HU. Females were more likely to have greater reduction in the rates of VOCs in comparison to their male counterparts (ß-estimate = 12.85, 95% CI [0.759-24.93], p = 0.0374). CONCLUSION: The use of HU results in a significant reduction in the rates of VOCs and emergency department visits. Future studies with robust research designs should be conducted to further examine the impact of HU on VOCs, hospitalization, and length of stay as well as compare HU to other newly approved medications for SCD, such as crizanlizumab.

Real-World Comparative Cost-Effectiveness Analysis of Different Classes of Disease-Modifying Therapies for Relapsing-Remitting Multiple Sclerosis in Saudi Arabia.

The very fact that multiple sclerosis (MS) is incurable and necessitates life-long care makes it one of the most burdensome illnesses. The aim of this study was to compare the cost-effectiveness of orally administered medications (e.g., fingolimod, dimethyl fumarate, and teriflunomide), interferon (IFN)-based therapy, and monoclonal antibodies (MABs) (e.g., natalizumab and rituximab) in the management of relapsing-remitting multiple sclerosis (RRMS) in Saudi Arabia using real-world data. This was a retrospective cohort study in which patients with RRMS aged ≥18 years without any other chronic health conditions with non-missing data for at least 12 months were recruited from the electronic health records of a university-affiliated tertiary care center. Multiple logistic regressions controlling for age, sex, and duration of therapy were conducted to examine the odds of disability progression, clinical relapse, MRI lesions, and composite outcome (e.g., relapse, lesion development on MRI, disability progression). The number of patients who met the inclusion criteria and were included in the analysis was 146. Most of the patients were female (70.51%) and young (e.g., ≤35 years of age). There were 40 patients on the orally administered agents (e.g., dimethyl fumarate, teriflunomide, fingolimod), 66 patients were on IFN-based therapy (e.g., Rebif®), and 40 patients were on monoclonal antibodies (e.g., rituximab and natalizumab). Patients on MABs had lower odds of the composite outcome (OR = 0.17 (95% CI: 0.068-0.428)). The use of orally administered agents was dominant (e.g., more effective and less costly), with average annual cost savings of USD -4336.65 (95% CI: -5207.89--3903.32) and 8.11% higher rate of effectiveness (95% CI: -14.81-18.07) when compared with Rebif®. With regard to the use of MABs in comparison to Rebif®, MABs were associated with higher cost but a better rate of effectiveness, with an average additional annual cost of USD 1381.54 (95% CI: 421.31-3621.06) and 43.11% higher rate of effectiveness (95% CI: 30.38-61.15) when compared with Rebif®. In addition, the use of MABs was associated with higher cost but a better rate of effectiveness, with an average additional annual cost of USD 5717.88 (95% CI: 4970.75-8272.66) and 35% higher rate of effectiveness (95% CI: 10.0-42.50) when compared with orally administered agents. The use of MABs in the management of RRMS among the young patient population has shown to be the most effective therapy in comparison to both IFN-based therapy (e.g., Rebif®) and orally administered agents, but with higher cost. Orally administered agents resulted in better outcomes and lower costs in comparison to IFN-based therapy. Future studies should further examine the cost-effectiveness of different disease-modifying therapies for the management of RRMS using more robust study designs.
