ABSTRACT

INTRODUCTION: As the incidence of mental disorders continues to rise, and pharmacy staff can significantly affect the willingness of patients with mental disorders to seek help; we aimed to evaluate the stigmatizing attitude of the pharmacy staff toward these patients in Iran.

METHODS: We conducted this cross-sectional study between April 2020 and December 2021 in Tehran, Iran, and included pharmacists, pharmacy technicians and pharmacy students, with the experience of working in a pharmacy for at least three months. The social distance scale (SDS) and dangerousness scale (DS) were used to measure the stigmatizing attitude of the participants. Higher scores indicated more stigmatizing attitudes.

RESULTS: We included a total of 186 participants with a mean age of 32.97 ± 9.41 years, of which 101 (54.3%) were male, and 75 (40.3%) were pharmacists, 101 (54.3%) were pharmacy technicians, and 8 (4.3%) were pharmacy students. The mean SDS score was 14.2 ± 4.13, and the mean DS score was 33.85 ± 8.92. The greatest tendency for social distance was reported for a patient with a mental disorder, ‘being the caretaker of their children for an hour or two’ and ‘marrying their children.’ The most perceived dangerousness was reported for a patient with a mental disorder ‘owning a gun.’ Positive personal history of psychopharmacological treatment was statistically correlated with lower DS (P = 0.001) and SDS (P = 0.007) scores. Positive family history of psychiatric inpatient admission was significantly correlated with higher DS (P = 0.05) and SDS (P = 0.03) scores. Higher rates of ‘received psychiatric prescriptions per month’ was associated with lower DS scores (P = 0.04).

CONCLUSION: Our participants did not have an overall positive attitude toward patients with mental disorders. Although, compared to previous studies, they held a more positive attitude. Positive personal history of psychopharmacological treatment predicted a more positive attitude and positive family history of psychiatric inpatient admission predicted a more negative attitude.

ABSTRACT

OBJECTIVE: The objective of this study is to investigate the impact of four natural product extracts, namely, aloe-emodin, quercetin, curcumin, and tannic acid, on the in vitro bacteriostatic properties and biocompatibility of gentamicin-loaded bone cement and to establish an experimental groundwork supporting the clinical utility of antibiotic-loaded bone cements (ALBC).

METHODS: Based on the components, the bone cement samples were categorized as follows: the gentamicin combined with aloe-emodin group, the gentamicin combined with quercetin group, the gentamicin combined with curcumin group, the gentamicin combined with tannic acid group, the gentamicin group, the aloe-emodin group, the quercetin group, the curcumin group, and the tannic acid group. Using the disk diffusion test, we investigated the antibacterial properties of the bone cement material against Staphylococcus aureus (n = 4). We tested cell toxicity and proliferation using the cell counting kit-8 (CCK-8) and examined the biocompatibility of bone cement materials.

RESULTS: The combination of gentamicin with the four natural product extracts resulted in significantly larger diameters of inhibition zones compared to gentamicin alone, and the difference was statistically significant (P < 0.05). Except for the groups containing tannic acid, cells in all other groups showed good proliferation across varying time intervals without displaying significant cytotoxicity (P < 0.05).

CONCLUSION: In this study, aloe-emodin, quercetin, curcumin, and tannic acid were capable of enhancing the in vitro antibacterial performance of gentamicin-loaded bone cement against S. aureus. While the groups containing tannic acid displayed moderate cytotoxicity in in vitro cell culture, all other groups showed no discernible cytotoxic effects.

ABSTRACT

BACKGROUND: Respiratory diseases are a major health burden, and educational inequalities may influence disease prevalence. We aim to evaluate the causal link between educational attainment and respiratory disease, and to determine the mediating influence of several known modifiable risk factors.

METHODS: We conducted a two-step, two-sample Mendelian randomization (MR) analysis using summary statistics from genome-wide association studies (GWAS) and single nucleotide polymorphisms (SNPs) as instrumental variables for educational attainment and respiratory diseases. Additionally, we performed a multivariable MR analysis to estimate the direct causal effect of each exposure variable included in the analysis on the outcome, conditional on the other exposure variables included in the model. The mediating roles of body mass index (BMI), physical activity, and smoking were also assessed.

FINDINGS: MR analyses provide evidence of genetically predicted educational attainment on the risk of FEV1 (β = 0.10, 95% CI 0.06, 0.14), FVC (β = 0.12, 95% CI 0.07, 0.16), FEV1/FVC (β = – 0.005, 95% CI – 0.05, 0.04), lung cancer (OR = 0.54, 95% CI 0.45, 0.65) and asthma (OR = 0.86, 95% CI 0.78, 0.94). Multivariable MR dicated the effect of educational attainment on FEV1 (β = 0.10, 95% CI 0.04, 0.16), FVC (β = 0.07, 95% CI 0.01, 0.12), FEV1/FVC (β = 0.07, 95% CI 0.01, 0.01), lung cancer (OR = 0.55, 95% CI 0.42, 0.71) and asthma (OR = 0.88, 95% CI 0.78, 0.99) persisted after adjusting BMI and cigarettes per day. Of the 23 potential risk factors, BMI, smoking may partially mediate the relationship between education and lung disease.

CONCLUSION: High levels of educational attainment have a potential causal protective effect on respiratory diseases. Reducing smoking and adiposity may be a target for the prevention of respiratory diseases attributable to low educational attainment.

ABSTRACT

BACKGROUND: Good vision highly depends on the transparency of the cornea, which is the “windscreen” of the eye. In fact, corneal blindness due to transparency loss is the second most common cause of blindness worldwide, and corneal transplantation is the main cure. Importantly, the cornea is normally avascular but can secondarily be invaded by pathological (blood and lymphatic) vessels due to severe inflammation, and the survival prognosis of a corneal graft mainly depends on the preoperative vascular condition of the recipient’s cornea. Whereas transplants placed into avascular recipient beds enjoy long-term survival rates of > 90%, survival rates significantly decrease in pathologically pre-vascularized, so-called high-risk recipients, which account for around 10% of all performed transplants in Germany and > 75% in lower and middle-income countries worldwide.

METHODS: This parallel-grouped, open-randomized, multicenter, prospective controlled exploratory investigator-initiated trial (IIT) intends to improve graft survival by preconditioning pathologically vascularized recipient corneas by (lymph)angioregressive treatment before high-risk corneal transplantation. For this purpose, corneal crosslinking (CXL) will be used, which has been shown to potently regress corneal blood and lymphatic vessels. Prior to transplantation, patients will be randomized into 2 groups: (1) CXL (intervention) or (2) no pretreatment (control). CXL will be repeated once if insufficient reduction of corneal neovascularization should be observed. All patients (both groups) will then undergo corneal transplantation. In the intervention group, remaining blood vessels will be additionally regressed using fine needle diathermy (on the day of transplantation). Afterwards, the incidence of graft rejection episodes will be evaluated for 24 months (primary endpoint). Overall graft survival, as well as regression of corneal vessels and/or recurrence, among other factors, will be analyzed (secondary endpoints).

DISCUSSION: Based on preclinical and early pilot clinical evidence, we want to test the novel concept of temporary (lymph)angioregressive pretreatment of high-risk eyes by CXL to promote subsequent corneal graft survival. So far, there is no evidence-based approach to reliably improve graft survival in the high-risk corneal transplantation setting available in clinical routine. If successful, this approach will be the first to promote graft survival in high-risk transplants. It will significantly improve vision and quality of life in patients suffering from corneal blindness.

ABSTRACT

OBJECTIVES: we performed this meta- analysis to investigate the impact of insulin receptor substrate 1 (IRS1) gene rs1801278 on susceptibility to gestational diabetes mellitus (GDM).

METHODS: The pooled odds ratio (OR) and 95% confidence interval (95% CI) were calculated, and p value is used to determine statistical significance. Sensitivity analysis was performed under three models (dominant, recessive and allele model), and the pooled ORs and 95%CI were calculated. Funnel plots and Begger’s regression test were employed to test the publication bias.

RESULTS: The meta-analysis included 4777 participants (2116 cases and 2661 controls). The IRS1 rs1801278 (C/T) were not significant associated with GDM risk under the dominant and allele models, OR (95%CI) = 1.22 (0.88-1.70) and 1.24 (0.91-1.68), respectively (both p values were more than 0.05). But we also found the IRS1 rs1801278 (C/T) were significant associated with GDM risk under the recessive model, OR (95%CI) = 0.37 (0.16-0.86), p = 0.030. Our results showed that none of the studies affected the quality of the pooled OR. We also found no significant publication bias existed in this meta study for three genetic models, P_{TT + CT vs. CC} = 0.445; P_{CC+CT vs. TT}= 0.095; P_{C vs. T} = 0.697.

CONCLUSION: this meta-analysis indicated that IRS1 rs1801278 (C/T) was associated with the GDM risk under the recessive model but was not associated with the GDM risk under dominant and allele models.

ABSTRACT

BACKGROUND: Antimicrobial stewardship programmes are needed in long-term care facilities (LTCFs) to tackle antimicrobial resistance. We aimed to identify factors associated with antibiotic use in LTCFs. Such information would be useful to guide antimicrobial stewardship programmes.

METHOD: We conducted a systematic review of studies retrieved from PubMed, Cochrane Library, Embase, APA PsycArticles, APA PsycINFO, APA PsycTherapy, ScienceDirect and Web of Science. We included quantitative studies that investigated factors associated with antibiotic use (i.e., antibiotic prescribing by health professionals, administration by LTCF staff, or use by residents). Participants were LTCF residents, their family, and/or carers. We performed a qualitative narrative synthesis of the findings.

RESULTS: Of the 7,591 screened records, we included 57 articles. Most studies used a longitudinal design (n = 34/57), investigated resident-level (n = 29/57) and/or facility-level factors (n = 32/57), and fewer prescriber-level ones (n = 8/57). Studies included two types of outcome: overall volume of antibiotic prescriptions (n = 45/57), inappropriate antibiotic prescription (n = 10/57); two included both types. Resident-level factors associated with a higher volume of antibiotic prescriptions included comorbidities (5 out of 8 studies which investigated this factor found a statistically significant association), history of infection (n = 5/6), potential signs of infection (e.g., fever, n = 4/6), positive urine culture/dipstick results (n = 3/4), indwelling urinary catheter (n = 12/14), and resident/family request for antibiotics (n = 1/1). At the facility-level, the volume of antibiotic prescriptions was positively associated with staff turnover (n = 1/1) and prevalence of after-hours medical practitioner visits (n = 1/1), and negatively associated with LTCF hiring an on-site coordinating physician (n = 1/1). At the prescriber-level, higher antibiotic prescribing was associated with high prescription rate for antibiotics in the previous year (n = 1/1).

CONCLUSIONS: Improving infection prevention and control, and diagnostic practices as part of antimicrobial stewardship programmes remain critical steps to reduce antibiotic prescribing in LTCFs. Once results confirmed by further studies, implementing institutional changes to limit staff turnover, ensure the presence of a professional accountable for the antimicrobial stewardship activities, and improve collaboration between LTCFs and external prescribers may contribute to reduce antibiotic prescribing.

ABSTRACT

BACKGROUND: Delayed recognition of compartment syndrome can result in devastating consequences such as the need for amputation or even death. Nurses are at the frontline of patient care and they must have a high index of suspicion for compartment syndrome. Even though nurses’ knowledge about the prevention of compartment syndrome is important, there are no studies in Ethiopia. Therefore this study aims to assess the knowledge and associated factors of nurses towards the prevention of post-traumatic compartment syndrome.

METHOD: An institutional-based cross-sectional study was conducted among 410 nurses from 26 April to 25 May 2023 at five Comprehensive Specialized Hospital. A stratified sampling technique was employed to recruit the required participants for the study. The data were collected using a structured self-administered questionnaire. The descriptive statistics were presented in text and tables. Analytical analysis schemes including bivariable and multivariable logistic regression were computed considering P-value < 0.05 to identify statistically significant factors.

RESULT: Nearly three- fifths (61.6%; 95% CI: 56.7 to 66.3) of nurses had adequate knowledge and significantly associated with being male (AOR: 1.615, 95% CI: 1.050-2.485), nurse use of guidelines (AOR: 2.079, 95% CI: 1.307-3.307), nurses they have been trained (AOR = 1.650; 95 CI: 1.063-2.562), and nurses’ who had more than 15 years’ (AOR: 4.207, 95 CI: 1.762-10.045) experience had good knowledge with respect to prevention of compartment syndrome than the counterparts.

CONCLUSION: Even though nurses’ knowledge regarding the prevention of post-traumatic compartment syndrome was found to be good, Diligent nursing assessment and monitoring of clinical signs should be critically performed. So, it is better to strengthen training, equip wards with standardized guidelines, and create a safe working environment should be routine activities.

ABSTRACT

BACKGROUND: Granulosa Cell Tumors (GCT) are considered the most frequent type of sex-cord stromal tumors. These tumors constitute 3-6% of neoplasms of the ovaries. GCTs are divided into 2 types: Juvenile GCT (JGCT) and Adult GCT (AGCT). Most patients are diagnosed early in the course of the disease and tend to have a favorable prognosis. In the surgical treatment of GCT, two main factors play role in the determination of feasibility of the surgery: age and tumor stage.

METHODS: A retrospective study was conducted on 65 consecutive female patients diagnosed with ovarian GCT at different hospitals across Lebanon who were referred to the National Institute of Pathology, Beirut-Lebanon, between January 2000 and January 2020. Then, they were divided according to types: adult versus juvenile type. Statistical analysis was carried out using Stata, version 16.

RESULTS: The incidence of GCT in a Lebanese population was 16.2 per million per year. The mean age of the studied population was 55.6 years. AGCT was the most common with a prevalence of 91% versus 19% for JGCT. Also, inhibine (the most important immunomarker) was found in 77.2% of adult cases. High mitotic index and high tumor size which are predictors for poor prognosis were respectively 20% and 36.9%. Concerning the histopathological features, Grooved nuclei and Exner bodies were less frequently observed in juvenile type (16.7% for both) compared to adult type (36.9%). Most patients with GCT were diagnosed in the early course of disease mainly due to the manifestation of the symptoms as abdominal pain, postmenopausal bleeding or intermenstrual bleeding, and the good diagnosis and screening practices in Lebanon. Regarding the recurrent cases, a significant correlation with high mitotic index (76.9%), high tumor size (92.3%) and advanced stage (46% for stage 3 and 46% for stage 4) was found with a p < 0.05.

CONCLUSIONS: The incidence of GCT in the Lebanese population is 16.2 per million per year. The majority of patients with GCT in Lebanon are of Adult type representing around 90% of cases. Older age, high mitotic index and big tumor size are predictors for poor outcomes.

ABSTRACT

BACKGROUND: The systems approach has been used to evaluate higher education and explores inputs, transformation process, and outputs of a system that is also influenced by environmental factors such as COVID-19. The COVID-19 pandemic shifted many college students to different learning modes, changing their university experience. This study evaluated dietetics students’ education experiences and characteristics in the latter period (spring 2022) of the COVID-19 pandemic using the systems approach.

METHODS: Researchers developed and distributed an electronic survey to all 215 US-based Didactic Program in Dietetics (DPD) directors during March to May 2022 to forward to their students. Researchers calculated descriptive statistics for variables related to inputs, transformation process, and outputs in the systems approach.

RESULTS: Respondents (n = 341) represented 51 DPDs in 31 states in the United States. Overall, DPD students (88.5%) were mostly or very satisfied with their choice of majoring in dietetics. Most (84.0%) planned to earn the RDN credential. Nearly half (46.9%) of DPD students were somewhat or extremely concerned about their readiness to continue their dietetics education path due to the pandemic-related learning conditions. Most students (43.6%) reported dissatisfaction with asynchronous remote instruction in laboratory courses. DPD students’ GPAs remained consistent within the range of 3.75-4.0 from Fall 2019 (43.2%) to Spring 2022 (44.5%). The most important expectations of professors moving forward were to communicate effectively (97.3%), employ cultural humility (93.8%), eliminate discrimination in the classroom (93.6%), provide lecture slides (89.7%), and be flexible and accommodating (88.7%).

CONCLUSIONS: DPD students emerged from COVID-19 with new perspectives and expectations for their university learning experience. Future research should explore the perspectives of DI directors, preceptors, and employers of COVID-19 era DPD graduates.

ABSTRACT

BACKGROUND: With an increasing collection of patient-reported outcomes (PROs) to measure health-related quality of life (HRQoL) in oncological patients, there is still a lack of standardised strategies on how to interpret and use these data in patient care. Prior research has shown support for the use of digital PRO monitoring together with alarm systems to notify clinicians when the PRO values are deteriorating. This system has demonstrated advantages in improving HRQoL and increasing survival rates among oncology patients. Hence, we designed the PRO B study, a superiority multi-centre randomised controlled trial, to investigate the effects of alarm-based monitoring in metastatic breast cancer patients in Germany. The study protocol for the PRO B study was published in September 2021, and this manuscript describes a formal statistical analysis plan (SAP) for the PRO B study to improve the transparency and quality of this trial.

METHODS AND DESIGN: The trial aimed to recruit 1000 patients with metastatic breast cancer. However, as of the completion of recruitment on June 15, 2023, we have successfully enrolled 924 patients from 52 breast cancer centres. Patients were 1:1 stratified randomised to the intervention and control groups. App-based PRO questionnaires are sent weekly to the intervention group and every 3 months to the control group. Only patients in the intervention group trigger an alarm if their PRO scores deteriorate, and they are subsequently contacted by the local care team within 48 h. The primary outcome is the fatigue score at 6 months, and secondary outcomes are other HRQoL and overall survival. Evaluation of the superiority of the intervention will be done using a linear mixed model with random intercepts for study centres.

CONCLUSION: This detailed SAP defines the main components of the statistical analysis for the PRO B study to assist the statistician and prevent bias in selecting analysis and reporting findings. Version 1 of the SAP was finalised on January 18, 2024.
