ABSTRACT

Drug-resistant Gram-negative bacterial infections, on average, increase the length of stay (LOS) in U.S. hospitals by 5 days, translating to approximately $15,000 per patient. We used statistical and machine-learning models to explore the relationship between antibiotic usage and antibiotic resistance over time and to predict the clinical and financial costs associated with resistant E. coli infections. We acquired data on antibiotic utilization and the resistance/sensitivity of 4776 microbial cultures at a Kaiser Permanente facility from April 2013 to December 2019. The ARIMA (autoregressive integrated moving average), neural networks, and random forest time series algorithms were employed to model antibiotic resistance trends. The models’ performance was evaluated using mean absolute error (MAE) and root mean squared error (RMSE). The best performing model was then used to predict antibiotic resistance rates for the year 2020. The ARIMA model with cefazolin, followed by the one with cephalexin, provided the lowest RMSE and MAE values without signs of overfitting across training and test datasets. The study showed that reducing cefazolin usage could decrease the rate of resistant E. coli infections. Although piperacillin/tazobactam did not perform as well as cefazolin in our time series models, it performed reasonably well and, due to its broad spectrum, might be a practical target for interventions in antimicrobial stewardship programs (ASPs), at least for this particular facility. While a more generalized model could be developed with data from multiple facilities, this study acts as a framework for ASP clinicians to adopt statistical and machine-learning approaches, using region-specific data to make effective interventions.

ABSTRACT

A thorough understanding of polypharmacy is required to create public health initiatives that minimize the potential for adverse outcomes. This study aimed to investigate the relationship between sociodemographic factors, socioeconomic status (SES), and polypharmacy risk in United States (US) individuals between 1999-2000 and 2017-2018. The cross-sectional National Health and Nutrition Examination Survey dataset covered ten cycles between 1999-2000 and 2017-2018. All individuals aged ≥18 years were included. The simultaneous use of at least five medications by one person is known as polypharmacy. Multivariable logistic regression showed that there was a statistically significant association between polypharmacy sociodemographic factors (such as age between 45 and 64 (odds ratio [OR] = 3.76; 95% confidence interval [CI] = 3.60-3.92; p < 0.0001) and age of 65 years or above (OR = 3.96; 95% CI = 3.79-4.13; p < 0.0001), especially women (OR = 1.09; 95% CI = 1.06-1.13; p < 0.0001), non-Hispanic blacks (OR = 1.66; 95% CI = 1.51-1.83; p < 0.0001), and veterans (OR = 1.27; 95% CI = 1.22-1.31; p < 0.0001)) and SES (such as being married (OR = 1.14; 95% CI = 1.08-1.19; p = 0.031), widowed, divorced, or separated (OR = 1.21; 95% CI = 1.15-1.26; p < 0.0001), a college graduate or above (OR = 1.21, 95% CI = 1.15-1.27, p < 0.0001), and earning > USD 55,000 per year (OR = 1.86; 95% CI = 1.79-1.93; p < 0.0001)). Individuals aged 45 years and above, women, and non-Hispanic blacks with higher educational levels and yearly incomes were more likely to experience polypharmacy in the US between 1999-2000 and 2017-2018.

ABSTRACT

The prevalence of depression and anxiety has increased day by day. Prejudice, self-stigma, and public stigma, on the other hand, continue to prevent patients from seeking adequate treatment, particularly in traditional communities. In this web-based, cross-sectional study, both the presence of depression and anxiety, and the knowledge, attitude, and awareness of first- and fifth (final)-year pharmacy students were examined via an online survey. The aim was to demonstrate the potential impact of public information and five years of pharmacy school on knowledge, attitude, and awareness. Our study population consisted of first- and fifth-year pharmacy students enrolled in one faculty of pharmacy during the spring semester of 2022-2023. The Beck Depression Inventory and Beck Anxiety Scale were utilized to measure the presence of depression and anxiety, while the Depression and Antidepressant Awareness and Knowledge Scale (DAKAS) was applied to assess their knowledge, attitude, and awareness. Fifth-year participants (n = 101) exhibited noticeably fewer stigmatizing attitudes than first-year participants (n = 104) (p < 0.05). There was no statistically significant difference between the mean Beck Depression Inventory and Beck Anxiety scores in first- and fifth-year pharmacy students. Being in the fifth class (OR: 3.690; p = 0.025), being of female gender (OR: 4.653; p < 0.001), and having a relationship with someone who took a psychotropic (OR: 3.060; p = 0.008) were associated with a lower overall stigma score by multiple linear regression analysis. The students’ awareness of antidepressants and familiarity with mental health issues at the end of their pharmacy education were higher and stigmatization behavior was lower than in first-year students. The positive attitudes at the end of their training towards depression will reduce the likelihood of future pharmacists’ patients from being exposed to stigmatization, prevents the formation of an additional stress factor, and likely will improve pharmacy practices.

ABSTRACT

Background and aim: Social prescribing, which links patients to non-clinical services and involves general physicians, has been gaining traction. Community pharmacists, who are integral to primary healthcare, have untapped potential in social prescribing. This study explores social prescribing competence among Norwegian community pharmacists and pharmacy students. Method: A cross-sectional study utilizing an anonymous online questionnaire to collect quantitative data was conducted. Inspired by the limited relevant literature, the questionnaire was constructed, pilot-tested, and distributed in a one-week window within a Facebook group for Norwegian pharmacists. The questionnaire comprised 23 questions categorized into demographic details and competence assessment, covering general knowledge, attitude, and barriers/facilitators related to social prescribing. Statistical analyses were employed to determine the competence of the participants. Results: The online questionnaire collected data from 96 participants, primarily females (79.2%), aged 25-34 (40.6%), who were identified as community pharmacists (49.0%). Most (91.7%) worked in community pharmacies, with 31.3% having over 10 years of experience. Despite positive client relationships (93.8%), statistical analysis revealed no significant associations between competence and variables such as work experience, education, or gender. The custom scoring system yielded an average competence score of 1.98 on a 5-point scale, with attitudes and perceptions of participants scoring 3.82. Overall competence was calculated at 3.4, indicating a moderate level. Conclusions: The findings of this study reveal that the participants had limited knowledge regarding social prescribing, emphasizing the need for education. However, the participants showed strong enthusiasm for competence development. This groundwork paves the way for future investigations centered on pilot-testing strategies to boost social prescribing knowledge and engagement among Norwegian community pharmacists and pharmacy students.

ABSTRACT

BACKGROUND: Prostate cancer (PCa) management is moving towards patient-tailored strategies. Advances in molecular and genetic profiling of tumor tissues, integrated with clinical risk assessments, provide deeper insights into disease aggressiveness. This study aims to offer a comprehensive overview of the pivotal genomic tests supporting PCa treatment decisions, analyzing-through real-world data-trends in their use and the growth of supporting literature evidence.

METHODS: A retrospective analysis was conducted using the extensive PearlDiver™ Mariner database, which contains de-identified patient records, in compliance with the Health Insurance Portability and Accountability Act (HIPAA). The International Classification of Diseases (ICD) and Current Procedural Terminology (CPT) codes were employed to identify patients diagnosed with PCa during the study period-2011 to 2021. We determined the utilization of primary tissue-based genetic tests (Oncocyte DX^®, Prolaris^®, Decipher^®, and ProMark^®) across all patients diagnosed with PCa. Subsequently, within the overall PCa cohort, patients who underwent radical prostatectomy (RP) and received genetic testing postoperatively were identified. The yearly distribution of these tests and the corresponding trends were illustrated with graphs.

RESULTS: During the study period, 1,561,203 patients with a PCa diagnosis were recorded. Of these, 20,748 underwent tissue-based genetic testing following diagnosis, representing 1.3% of the total cohort. An increasing trend was observed in the use of all genetic tests. Linear regression analysis showed a statistically significant increase over time in the use of individual tests (all p-values < 0.05). Among the patients who underwent RP, 3076 received genetic analysis following surgery, representing 1.27% of this group.

CONCLUSIONS: Our analysis indicates a growing trend in the utilization of tissue-based genomic testing for PCa. Nevertheless, they are utilized in less than 2% of PCa patients, whether at initial diagnosis or after surgical treatment. Although it is anticipated that their use may increase as more scientific evidence becomes available, their role requires further elucidation.

ABSTRACT

BACKGROUND: The quality of life for people with chronic illnesses like cancer has been shown to be significantly impacted by self-efficacy and perceptions of their illness.

OBJECTIVES: This study investigates the relationship between cancer patients’ perceptions of their illness, their self-efficacy beliefs, and their quality of life.

METHOD: Conducted from December 2022 to February 2023, this research involved 120 adults undergoing cancer treatment. We utilized the Illness Perception Questionnaire (IPQ), the Arabic version of the Cancer Behavioral Inventory Brief (CBI-B), and the Arabic EORTC QLQ-C30, alongside clinical data collection. Statistical analyses included Pearson correlation and descriptive statistics.

RESULTS: Breast cancer emerged as the most common type among participants. A positive correlation was found between self-efficacy and quality of life, as measured by the EORTC QLQ-C30, particularly in relation to symptom management. Interestingly, all dimensions of illness perception correlated with quality of life, except for control and concerns.

CONCLUSIONS: The findings underscore the vital role of nurses and healthcare providers in aiding cancer patients to develop and utilize self-management strategies effectively. The study reveals that a patient’s capacity to manage their illness is significantly influenced by their confidence, understanding of their condition, and overall quality of life. Addressing these aspects can greatly enhance healthcare professionals’ contribution to improving the resilience and well-being of individuals battling cancer.

ABSTRACT

BACKGROUND: Breast cancer is the most frequent malignancy in women worldwide and one of the most curable cancers if diagnosed at an early stage. Female patients presenting solid breast lesions are greatly predisposed to breast cancer development, and as such, effective screening of high-risk patients is valuable in early-stage breast cancer detection.

OBJECTIVES: The aim of our study was to identify the most relevant demographic, reproductive and lifestyle risk factors for breast cancer among women with solid breast lesions living in western Romania, namely the urban region consisting of Timisoara and the rural surrounding regions.

METHODS: From January 2017 to December 2021, 1161 patients with solid breast lesions, as detected by sonoelastography, were divided into two groups: patients with benign lesions (1019, 87.77%) and patients with malignant nodules (142, 12.23%). The malignancy group was confirmed by a histopathological result. Variables including age, BMI, menarche, menopause, years of exposure to estrogen, number of births, breastfeeding period, use of oral combined contraceptives, smoker status, family medical history and living area (rural-urban) were recorded.

RESULTS: It was evidenced by our study that the main risk factors for malignancy were elevated age (OR = 1.07, 95% CI 1.05-1.08), BMI (OR = 1.06, 95% CI 1.02-1.10), living area (rural) (OR = 1.86, 95% CI 1.13-2.85) and family medical history (negative) (OR 3.13, 95% CI 1.43-8.29). The other proposed risk factors were not found to be statistically significant.

CONCLUSIONS: Age and BMI were observed to be the most significant factors for breast cancer risk increase, followed by living in a rural area. A family history of breast cancer was shown to be inversely correlated with cancer risk increase.

ABSTRACT

This systematic review and meta-analysis aimed to evaluate the analgesic efficacy and adverse effects of celecoxib after total knee arthroplasty. Keywords in the PubMed and Scopus databases were used to find article abstracts. Each included clinical trial was assessed using the Cochrane Collaboration risk of bias tool, and we extracted data on postoperative pain assessment using the Visual Analogue Scale (VAS) at rest, ambulation, and active range of motion, rescue analgesic intake, and adverse effects. Inverse variance tests with mean differences were used to analyze the numerical variables. The Mantel-Haenszel statistical method and the odds ratio were used to evaluate the dichotomous data. According to this qualitative assessment (n = 482), two studies presented conclusions in favor of celecoxib (n = 187), one showed similar results between celecoxib and the placebo (n = 44), and three clinical trials did not draw conclusions as to the effectiveness of celecoxib versus the placebo (n = 251). Moreover, the evaluation of the rescue analgesic intake showed that the patients receiving celecoxib had a lower intake compared to patients receiving a placebo (n = 278, I² = 82%, p = 0.006, mean difference = -6.89, 95% IC = -11.76 to -2.02). In conclusion, the pooled analysis shows that administration of celecoxib alone results in a decrease in rescue analgesic consumption compared to a placebo after total knee surgery.

ABSTRACT

We examined neurite orientation dispersion and density imaging in patients with migraine. We found that patients with medication overuse headache exhibited lower orientation dispersion than those without. Moreover, orientation dispersion in the body of the corpus callosum was statistically negatively correlated with migraine attack frequencies. These findings indicate that neurite dispersion is damaged in patients with chronic migraine. Our study results indicate the orientation preference of neurite damage in migraine.

ABSTRACT

To determine the usefulness of combining two methodologies (OSCE and escape room) in a scenario simulation to evaluate a subject, and determine the evaluation of the students of this experience. An observational cross-sectional study was carried out with students enrolled in a sexual and reproductive health-care course as a part of their nursing degree. The students had to solve four clinical cases based on the contents of the teaching practices of the subject by solving clues that led them to carry out procedures and techniques and provide care in scenario simulators. Students evaluated the experience using the GAMEX (Gameful Experience in Gamification) scale. Mean differences were estimated with their respective 95% confidence intervals. A total of 124 students participated. Of these, 63.7% (79) solved the clinical cases with their knowledge and skills. Most (80.6%, 100) students stated that they completely remembered and applied the knowledge of the topic during the game. Almost all (98.4%, 122) would recommend this experience. The dimensions with the best rating on the GAMEX scale were “fun”, with an average score of 4.7 points (0.49), followed by “critical thinking”, with 4.2 (0.59). Women presented statistically better scores than men (mean difference: 1.58; 95% CI: 0.55, 2.61). The OSCE combined with an escape room using scenario simulations may be a useful tool to evaluate the subject. In addition, the students were satisfied, had fun, and recommended the experience. This study was not registered.
