Comparative Clinical Implications of Calcified versus Non-Calcified Tissue Protrusion After Coronary Stent Implantation

Purpose

The prognostic implications of calcified versus non-calcified tissue protrusions (TPs) following stent implantation remain undetermined. This study aimed to evaluate the differential clinical outcomes associated with calcified and non-calcified TP morphologies.

Patients and Methods

Employing intravascular ultrasound (IVUS), we identified calcified TPs as calcium fragment extrusions permeating the stent struts, while non-calcified TPs were characterized as plaque and/or thrombus extensions through the stent into the arterial lumen. The primary endpoint encompassed target lesion failure (TLF), comprising cardiac death, target vessel myocardial infarction, clinically driven target lesion revascularization (TLR), or stent thrombosis, assessed in patients with a follow-up period exceeding one year.

Results

Of 1033 patients subjected to pre- and post-intervention IVUS, 62 exhibited calcified TPs (6.0%), and 279 presented non-calcified TPs (27.0%), forming the basis of this analysis. Multivariable linear regression indicated calcified nodules as a significant predictor of calcified TP [Odds Ratio (OR) 2.47; 95% Confidence Interval (CI) 2.33 to 2.62; P <0.001], with ST-segment elevation myocardial infarction emerging as an inverse correlate [OR 0.82; 95% CI 0.73 to 0.93; P = 0.004]. Two-year data revealed a higher incidence of TLF in patients with calcified TPs versus their non-calcified counterparts (11.3% vs 2.2%, P <0.001), and a marked increase in clinically driven TLR (9.7% vs 1.4%, P <0.001). Calcified TPs were independently correlated with increased TLF risk in the adjusted model [Hazard Ratio (HR) 2.47; 95% CI 1.17 to 5.16; P = 0.027].

Conclusion

After drug-eluting stent implantation, IVUS-identified calcified TPs correlate with adverse clinical outcomes compared to non-calcified TP formations.

A Rare-Earth Near-Infrared Nanoprobe for the Identification of Small Cell Lung Cancer

Background

Small cell lung cancer (SCLC) is a common subtype of lung cancer, and there is currently no established method for the early identification of SCLC. We prepared a novel rare-earth near-infrared (NIR) downconversion nanoprobe to identify SCLC cells.

Methods

The shell precursors Gd-OA and Na-TFA-OA were prepared, and the NaYF4:Nd@NaGdF4-ProGRP antibody probe was obtained after synthesizing downconversion fluorescent nanocrystals. The probe was used for NIR identification of cancer cells and subcutaneous tumors in nude mice. The biotoxicity of the probe to SCLC cells and nude mice was studied.

Results

The NaYF4:Nd@NaGdF4-ProGRP antibody probe was successfully prepared, with a size of 44 nm, an NIR emission peak at approximately 1060 nm, and a concentration of 40 μmol/mL. The probe could achieve accurate NIR identification of SCLC cells and subcutaneous tumors in nude mice. Optimal images of the subcutaneous tumor model were obtained approximately 10 minutes after probe injection. There was no significant change in the hematology indices, respiratory rate, or heart rate of nude mice after the probe was injected (all P > 0.05).

Conclusion

We have successfully prepared a low-toxicity probe that can identify SCLC cells, which may be useful for the early detection of SCLC. And conduct theoretical exploration for non-invasive identification and identification of some early metastatic lesions without pathological sampling in the future.

Effect of Continuation-Maintenance Electroconvulsive Therapy on Hospitalization: A Retrospective Mirror-Image Study

Objective

To examine the effect of continuation-maintenance electroconvulsive therapy (ECT) on psychiatric hospitalization in Thai patients.

Methods

This retrospective mirror-image study reviewed medical records of Thai patients who received continuation-maintenance ECT at Ramathibodi Hospital, Bangkok, between September 2013 and December 2022. The initiation of continuation-maintenance ECT served as the index event, establishing pre-initiation and post-initiation periods. The primary outcome measured the differences in admissions and admission days before and after continuation-maintenance ECT.

Results

Forty-seven patients were included in the study, with diagnoses of schizophrenia (38.3%), schizoaffective disorder (21.3%), and bipolar disorder (19.1%) being the most common. The mean (standard deviation; SD) age was 44.6 (12.2) years. The total duration that patients received continuation-maintenance ECT was 53 ± 38.2 months. Following the initiation of ECT, there was a significant reduction in the median (interquartile range) number of hospitalizations for all patients (2 [2] versus 1 [2], p < 0.001), as well as for the psychotic disorder group (2 [2] versus 1 [2.75], p = 0.006) and the mood disorder group (2 [2] versus 1 [2], p = 0.02). Moreover, there was a significant reduction in the median (interquartile range) length of admission days for all patients after the initiation of continuation-maintenance ECT (66 [69] versus 20 [53], p < 0.001). Specifically, the psychotic disorder group (64.5 [74] versus 15.5 [62], p = 0.02) and mood disorder group (74 [57] versus 20 [54], p = 0.008) demonstrated statistically significant decreases in admission days.

Conclusion

Continuation-maintenance ECT may be an effective treatment option for reducing hospitalizations and admission days in patients with various psychiatric diagnoses. However, the study also highlights the need to carefully consider the potential adverse effects of ECT in clinical decision-making.

Dietary Intake, Stress, Anxiety, and Satisfaction with Nutrition Services in Patients with and without COVID-19

Background

Dietary intake constitutes a fundamental support in hospitalized patients to reduce morbimortality, risk of complications, and hospital stay.

Objective

We compared dietary intake, stress, anxiety, and satisfaction with the nutrition service in patients with and without COVID-19; we also analyzed the correlation between the variables mentioned.

Methods

A cross-sectional, comparative, and correlational study was carried out. A total of 215 patients were selected by non-probability convenience sampling (97 with COVID-19 and 118 without COVID-19).

Results

Patients with COVID-19 presented a higher percentage of "all the dish served" consumption (63.9%), as well as a higher percentage of "high" anxiety (18.6%) and "very high" satisfaction (28.9%) compared to their counterparts without COVID-19. The stress variable was predominantly moderate in both groups (57.7% vs 55.9%). Statistically significant and indirect correlation was found between satisfaction and stress level (rho = -0.289; p<0.01) in patients without COVID-19; similarly, between intake and stress level (rho =-.254; p<0.05) in patients with COVID-19. Both groups presented a statistically significant and direct correlation between anxiety and stress level (rho =0.432 without COVID-19, rho = 0.525 with COVID-19; p<0.01).

Conclusion

The findings suggest a multidisciplinary intervention, in which the improvement of mental health in the study population is contemplated and to coadunate the negative effects on the perception of the quality of care of the nutrition service and on dietary intake.

Individual Characteristics That Promote or Prevent Psychological Safety and Error Reporting in Healthcare: A Systematic Review

Background

Healthcare errors continue to be a safety issue and an economic burden that causes death, increased length of stays, and emotional trauma to families and the person who commits the error.  Speaking up and error reporting within a safety culture can reduce the incidence of error; however, this is complex and multifaceted.

Aim

This systematic review investigates individual characteristics that support or prevent speaking up behaviors when adverse events occur.  This study further explores how organizational interventions designed to promote error reporting correlate to individual characteristics and perceptions of psychological safety.  .

Methods

A systematic review of peer-reviewed articles in healthcare that contain characteristics of an individual that promote or prevent error reporting was conducted. The search yielded 1233 articles published from 2015 to 2021. From this set, 81 full-text articles were assessed for eligibility and ultimately extracted data from 28 articles evaluated for quality using Joanna Briggs Institute critical appraisal tools©.

Principal Findings

The primary themes for individual character traits, values, and beliefs that influence a person's decision to speak up/report an error include self-confidence and positive perceptions of self, the organization, and leadership. Education, experience and knowledge are sub themes that relate to confidence. The primary individual characteristics that serve as barriers are 1) self-preservation associated with fear and 2) negative perceptions of self, the organization, and leadership.

Conclusion

The results show that an individual's perception of their environment, whether or not it is psychologically safe, may be impacted by personal perceptions that stem from deep-seated personal values. This exposes a crucial need to explore cultural and diversity aspects of healthcare error reporting and how to individualize interventions to reduce fear and promote error reporting.

Integrating Medical Simulation into Residency Programs in Kingdom of Saudi Arabia

PURPOSE

This study conducted a simulation needs assessment on diverse ongoing residency training programs supervised by the Saudi Commission for Health Specialties (SCFHS) in Saudi Arabia. The goal was to develop a standardized methodological approach to integrate simulation as a teaching tool for any ongoing training program.

METHODS

A mixed-methods approach is used in four steps to focus on top educational needs and integrate simulation into the curriculum. The first step was the selection of 38 residency training programs based on the scoring criteria tool. Of these, nine were selected as target programs. The next step was champion recruitment, where two faculty representatives from each specialty were trained to become specialty champions. The third step was a targeted audience needs assessment, consisting of four phases: curriculum review; a targeted audience survey; stakeholders' interview; and selection of top educational requirements generated by the first three phases. Lastly, the fourth step used an integration simulation sheet to build common themes for incorporating simulation into the program curriculum.

RESULTS

Out of 38 programs, the nine selected top-ranked specialties completed the process, and roadmaps were developed. Using the combined list of all skills and behaviors, the final score proportion was calculated and then ranked. A list of the top needed skills and behaviors was compiled as follows: Obstetrics and Gynecology 10/84, Emergency Medicine (ER) 80/242, Intensive Care Unit 20/139, Internal Medicine (IM) 37/102, Pediatric 82/135, Ear, Nose, and Throat (ENT) 49/125, General Surgery (GS) 55/114, Plastic Surgery 24/165, and Family Medicine (FM) 59/168.

CONCLUSION

Findings from this process could be used by the supervisory bodies at a country level and assist decision-makers to determine which criteria to use in the needs assessment to integrate simulation into any ongoing residency training program.

Career Readiness Among Saudi Pharmacy Students: Exploring the Need for and the Impact of Career Counseling Services

PURPOSE

Employers place emphasis on graduates' work experience and interpersonal skills while academia mainly focuses on developing students' learning ability. One proposed strategy is through career guidance by universities; however, supportive evidence is lacking. This study explored the career readiness of pharmacy students for the Saudi job market. It also examined the availability of career guidance services for pharmacy students and alumni in Saudi Arabia and the impact of such services on recipients' career path choices and development of competencies.

SUBJECTS AND METHODS

This cross-sectional study utilized an online-based survey. Pharmacy students in the last three years of their program and recent graduates participated in the survey. The study used descriptive statistics to describe participants' demographic data. Respondents were asked to rate aspects related to career readiness on a 5-point Likert scale, and their responses were reported as frequencies with percentages or means as appropriate. Comparisons between groups were made using t-test or one- way ANOVA as required.

RESULTS

A total of 576 responses were collected. About 25% of participants acknowledged the career guidance services provided at their pharmacy college, whereas the majority indicated that they have never reached out to a career counselor at their university (89.6%). The highest level of disagreement was noticed in impact of career guidance services on participants' establishment of their CV/portfolio (50.7%). Using the work readiness scale, the lowest mean was seen in the social intelligence domain (3.64 ± 0.94).

CONCLUSION

Although substantial proportion of students reported the presence of career guidance services in their university or college, very few stated that they had utilized such services. This could have impacted the students' career readiness for the rapidly changing Saudi job market. Therefore, proper measures to advertise the availability of career guidance services in Saudi pharmacy schools have to be implemented.

Long-Term Survival with Ibrutinib Therapy in Elderly Patients with Newly Diagnosed Primary Central Nervous System Lymphoma

Primary central nervous system lymphoma (PCNSL) carries a dismal prognosis in elderly patients above 70 years of age with a median overall survival of 6 months. Novel therapeutic agents are urgently needed to improve survival outcomes in this age group. We describe the clinical presentation, diagnostic workup, and treatment outcome in two 80-year-old patients diagnosed with PCNSL who were treated with ibrutinib therapy. Both patients remain in complete remission following treatment with ibrutinib therapy. One patient is currently 4 years and the other is 2 years and 9 months from the time of initial diagnosis. We suggest that ibrutinib therapy has significant therapeutic activity against PCNSL in the newly diagnosed setting and should be evaluated in a clinical trial as part of front-line therapy, especially in elderly patients.

Severe Carbamazepine Toxicity Treated with Continuous Venovenous Hemofiltration at Palestine Medical Complex: Two Case Reports

Carbamazepine intoxication is not uncommon and accounts for many cases of poisoning among anticonvulsive medications users. Since there is no specific antidote for carbamazepine overdose, management is limited to gastric decontamination and supportive therapy. With its high protein binding, the role of extracorporeal elimination in carbamazepine intoxication is still questionable. Here two cases of severe carbamazepine intoxication are presented; the cases were brought to the emergency department after the ingestion of 12,000 mg of controlled release carbamazepine for the first case, and unknown amounts of the same drug for the second case. Both cases were presented with altered mental status, convulsion, and high serum carbamazepine levels of more than 20 mcg/mL. They were intubated and treated with continuous venovenous hemofiltration, after which carbamazepine levels declined significantly along with subsequent clinical improvement and complete neurological recovery. Both cases were discharged home for further psychiatric care.

An Assessment of the Knowledge and Practices of Adults in Jazan, Saudi Arabia, Concerning Routine Medical Checkups

PURPOSE

This study aims to measure the knowledge and practices of adults in the Jazan region of Saudi Arabia concerning routine medical checkups.

METHODS

This study used a cross-sectional design that targeted adults in the Jazan region of Saudi Arabia. The data was collected via self-administered questionnaires, with participants being approached in online settings. The questionnaires measured participant demographics, knowledge, and practice of routine medical checkups as well as their response to the Know Your Numbers campaign services initiative from the Saudi Ministry of Health. A chi-square test was used to detect statistically significant differences between the levels of knowledge and practice according to the measured demographic characteristics.

RESULTS

A total of 516 persons participated in this study. The mean age of the participants was 25 years; 54.7% were female. The median level of knowledge was 3 (out of 9), varying between 0 and 9. The recruited sample exhibited average knowledge of parameters used to classify levels of blood glucose, blood pressure, body mass index, and blood lipids, but low knowledge regarding the recommended age to begin screening for several chronic diseases. Factors associated with levels of knowledge were gender, age, education level, and employment (p value < 0.05). However, a history of chronic disease was the only factor associated with the practice of routine medical checkups (p value 0.023). Finally, less than 5% of this sample reported their participation in the Know Your Numbers campaign.

CONCLUSION

Attending routine medical checkups is uncommon and only motivated by the existence of a diagnosed medical condition. Furthermore, this study found low utilization of the Know Your Numbers campaign services. This suggests a need for greater emphasis on increasing awareness of routine medical checkups among adults in the Jazan region.

The Impact of Non-Compliance to a Standardized Risk-Adjusted Protocol on Recurrence, Progression, and Mortality in Non-Muscle Invasive Bladder Cancer

PURPOSE

Non-muscle invasive bladder cancer (NMIBC) is a potentially curable or controllable disease if strict adherence to a surveillance protocol is followed. Management and surveillance of NMIBC begins at the time of diagnosis up to a few years thereafter. There is scanty data in the literature evaluating the impact of non-compliance with the surveillance protocols on progression, recurrence, and mortality rate.

PATIENTS AND METHODS

An observational, retrospective cohort study recruited data between 2012 and 2017 at two tertiary hospitals. Data were collected consecutively. NMIBC patients who had at least 3 years of follow-up data were included. Patients were divided into different groups based on their compliance with the cystoscopy follow-up protocol as recommended by the European guidelines. We compared the cystoscopy compliant group with the non-compliant group in view of recurrence, progression, and mortality. In addition, missing variable items during surveillance were calculated using a new scoring model to predict adverse outcomes.

RESULTS

Eighty-eight NMIBC patients met our criteria. Recurrence rate (RR), progression rate (PR), metastasis rate (MsR), and mortality rate (MR) are significantly higher in non-compliant group, RR: (92.6%) (P<0.001), PR: (54.1%) (P<0.001), MsR: (37.7%) (P<0.001), MR: (23.5%) (P= 0.002) respectively. In the subgroup analysis, intermediate and high-risk groups have a PR rate of zero in the compliant group, while it is 100% (P<0.001) and 56.4% (P=0.001) in the non-compliant group, respectively. Use of a Kaplan Meier (KM) graph shows that compliant patients had a better survival in comparison to non-compliant patients. Scoring there or more is statistically and clinically significantly associated with higher recurrence, progression, and mortality. RR: (94%) (P=0.016), PR: 49% (P<0.001) and MR (26%) (P=0.012).

CONCLUSION

Non-compliance to a standardized surveillance protocol in NMIBC is associated statistically and clinically with adverse outcomes in comparison to a compliant group. This mandates strict adherence to surveillance guidelines particularly in patients with high-risk disease.
