Objective: Although pharmaceutical care provision is the primary goal of the pharmacy profession, its actual implementation has been lacking in developing nations. Therefore, this study investigated pharmacy professional’s understanding, attitudes, and practice toward pharmaceutical care. Methods: A cross-sectional study was conducted from 30 July 2022 to 30 August 2022, at all community and hospital pharmacies in Motta town, Northwest Ethiopia. Data were gathered using a self-administered questionnaire and analyzed using SPSS version 26.0. A logistic regression model with a p-value of 0.05 and a 95% confidence interval was applied to identify factors associated with understanding, attitude, and practice. Result: The study had a 97.7% response rate. Of the 130 participants, 71 (54.6%) were females. Slightly more than half (56.2%) of the participants were aware of the aim (56.2%) of pharmaceutical care and responsibilities (56.9%) of pharmacy professionals in the pharmaceutical care process. However, most participants lack awareness of the similarities and differences between clinical pharmacy and pharmaceutical care. Concerning their attitude, most participants (66.9%) believed that pharmaceutical care provision should be the primary responsibility of pharmacy professionals, and it will benefit patients (61.6%) and the healthcare system (60.8%). Pharmacy professionals frequently evaluate their patients and identify health or drug therapy-related problems and potentially available therapeutic alternatives. However, they rarely engaged in any health screening activities or provided feedback to the doctor on the patient’s progress. Training status, sex, and years of practice/understanding were significantly related to pharmacy professionals’ level of understanding, attitudes, and practice toward pharmaceutical care, as both years of practice and understanding are related to practice. Conclusion: Our study revealed a deficit in pharmacy professionals’ understanding, attitude, and practice toward pharmaceutical care in Motta town, Northwest Ethiopia. Policymakers, health authorities, and educational institutions should work together to develop strategies and instructional initiatives that optimize pharmaceutical care provision and thus achieve optimal patient outcomes and lower healthcare costs.

Abstract
Background
Proteomics and metabolomics offer substantial potential for advancing kidney transplant research by providing versatile opportunities for gaining insights into the biomolecular processes occurring in donors, recipients, and grafts. To achieve this, adequate quality and numbers of biological samples are required. Whilst access to donor samples is facilitated by initiatives such as the QUOD biobank, an adequately powered biobank allowing exploration of recipient-related aspects in long-term transplant outcomes is missing. Rich, yet unverified resources of recipient material are the serum repositories present in the immunological laboratories of kidney transplant centers that prospectively collect recipient sera for immunological monitoring. However, it is yet unsure whether these samples are also suitable for -omics applications, since such clinical samples are collected and stored by individual centers using non-uniform protocols and undergo an undocumented number of freeze–thaw cycles. Whilst these handling and storage aspects may affect individual proteins and metabolites, it was reasoned that incidental handling/storage artifacts will have a limited effect on a theoretical network (pathway) analysis. To test the potential of such long-term stored clinical serum samples for pathway profiling, we submitted these samples to discovery proteomics and metabolomics.

Methods
A mass spectrometry-based shotgun discovery approach was used to obtain an overview of proteins and metabolites in clinical serum samples from the immunological laboratories of the Dutch PROCARE consortium. Parallel analyses were performed with material from the strictly protocolized QUOD biobank.

Results
Following metabolomics, more than 800 compounds could be identified in both sample groups, of which 163 endogenous metabolites were found in samples from both biorepositories. Proteomics yielded more than 600 proteins in both groups. Despite the higher prevalence of fragments in the clinical, non-uniformly collected samples compared to the biobanked ones (42.5% vs 26.5% of their proteomes, respectively), these fragments could still be connected to their parent proteins. Next, the proteomic and metabolomic profiles were successfully mapped onto theoretical pathways through integrated pathway analysis, which showed significant enrichment of 79 pathways.

Conclusions
This feasibility study demonstrated that long-term stored serum samples from clinical biorepositories can be used for qualitative proteomic and metabolomic pathway analysis, a notion with far-reaching implications for all biomedical, long-term outcome-dependent research questions and studies focusing on rare events.

Abstract
Background
Sono-photodynamic therapy (SPDT), which combines photodynamic (PDT) and sonodynamic (SDT) therapies with sensitizers, offers new avenues for cancer treatment. Even though new sensitizers for SPDT have been synthesized with great success, few of them are effectively used. The limited tumor-targeting specificity, inability to transport the sensitizers deeply intratumorally, and the deteriorating tumor microenvironment limit their anti-tumor effectiveness. The current study was carried out aiming at high-frequency ultrasound-assisted drug delivery of chia, cress and flax conjugated hematite iron oxide nanoparticles (CCF–HIONP) for photothermal–photodynamic lung cancer (LCA) treatment in vitro and in vivo as activated cancer treatment up-to-date modality.

Materials and methods
The study was conducted in vitro on human LCA cells (A-549) and the study protocol application groups in vivo on Swiss albino mice treated with benzo[a]pyrene only and were not received any treatment for inducing LCA, and only after LCA induction the study treatment protocol began, treatment was daily with CCF–HIONP as HIFU–SPDT sensitizer with or without exposure to laser (IRL) or high-frequency ultrasound (HIFU–US) or a combination of laser and/or high-frequency ultrasound for 3 min for 2 weeks.

Results
Revealed that HIONP can be employed as effective CCF delivery system that directly targets LCA cells. In addition, CCF–HIONP is a promising HIFU–SPS for HIFU–SPDT and when combined with HIFU–SPDT can be very effective in treatment of LCA–A549 in vitro (cell viability decreased in a dose-dependent basis, the cell cycle progression in G0/G1 was slowed down, and cell death was induced as evidenced by an increase in the population of Pre-G cells, an increase in early and late apoptosis and necrosis, and an increase in autophagic cell death) and benzo[a]pyrene LCA-induce mice in vivo (decreased oxidative stress (MDA), and ameliorated enzymatic and non-enzymatic antioxidants (SOD, GR, GPx, GST, CAT, GSH, and TAC) as well as renal (urea, creatinine) and hepatic (ALT, AST) functions, induced antiproliferative genes (caspase 3,9, p53, Bax, TNFalpha), suppressed antiapoptotic and antiangiogenic genes (Bcl2,VEGF respectively) and effectively reducing the growth of tumors and even leading to cancer cell death. This process could be attributed to photochemical and/or high-frequency sono-chemical activation mechanism HIFU–SPDT.

Conclusions
The results indicate that CCF–HIONP has great promise as an innovative, effective delivery system for selective localized treatment of lung cancer that is activated by HIFU–SPDT.

AbstractTransition to online teaching during the first wave of the COVID-19 pandemic has led to various concerns about educational quality. The study investigates the consequences of this transition on student performance for a prominent university in Northern Italy. Comprehensive administrative data allows us to monitor students’ performance and to have detailed socioeconomic information about them. Using a difference-in-differences design with lecturer fixed effects, we exploit the unique timing of the lockdown that fell together with the start of the summer term in 2020. We find no marked effects on students’ average grades in higher education in the immediate aftermath of the lockdown.

Abstract
Background
Research on Irritable Bowel Syndrome (IBS) among medical students has increased globally, highlighting a high prevalence in this demographic. However, there is a lack of data specifically regarding the prevalence of IBS among medical students in Yemen. This study aimed to investigate the prevalence and associated factors of IBS among Yemeni medical students.

Methods
We conducted a cross-sectional study involving medical students who completed a validated self-administered questionnaire incorporating socio-demographic information, dietary habits, smoking status, sleep patterns, and the Rome IV criteria for IBS. We used bivariate and multivariate logistic regression models to identify IBS’s associated factors, estimated as odds ratios (ORs) with 95% confidence intervals (CIs) and average marginal effect (AME) on the predicted probability of IBS.

Results
The study included 351 medical students with a mean age of 22.53 ± 2.70 years; 39.60% (139) were females. The prevalence of IBS was 26.21% (92 students), with 67.39% (62) of them classified as IBS-M (mixed). In multivariable analysis, the consumption of carbonated soft drinks remained significantly associated with IBS (OR: 3.35; 95% CI: 1.14–9.88; P = 0.028). In males, coffee consumption had a substantial effect on the predicted probability of IBS (AME: 11.41%; 95% CI: 0.32–22.60). In females, the consumption of carbonated soft drinks had a significant effect on the predicted probability of IBS (AME: 24.91%; 95% CI: 8.34–41.48).

Conclusion
The consumption of carbonated soft drinks is significantly associated with IBS among medical students, with a particularly notable increase in the predicted probability of IBS in females. These findings highlight the necessity for gender-specific dietary recommendations in IBS management. Further research is essential to investigate IBS in the general population to gain a comprehensive understanding of its prevalence and associated factors.

Abstract
Background
Economic sanctions are defined as restrictions imposed by other countries against individuals, groups, or governments of other countries. These sanctions have a detrimental impact on the economies of countries and can also limit access to healthcare services for people as a secondary consequence. This study aims to systematically review the literature to examine the direct and indirect effects of economic sanctions on health through a narrative synthesis.

Methods
This systematic literature review was limited to papers published between January 1990 and July 2023. Relevant documents published in English and Persian were searched for in databases including Cochrane Library, PubMed, Embase, Scopus, Web of Science, SID, Magiran, and Irandoc. The direct and indirect effects of sanctions on health were classified using two frameworks proposed by the World Health Organization (WHO): the Health System Building Blocks and “Social Determinants of Health”.

Results
Out of a total of 18,219 articles, 59 were selected based on inclusion criteria. The effects of sanctions were divided into direct and indirect groups. Direct effects encompassed seven main themes: access to essential medicine, medical products, vaccines and technologies; financing; health workforce; service delivery; research and health information systems; health outcomes; and financial risk protection. Indirect effects also were classified into six main themes: socioeconomic status; food and agricultural products; stress; early life conditions; high-risk behaviors and addiction; and transport. Most studies focused on the access to medicines, food, economic and social status.

Conclusions
Economic sanctions have had profoundly negative impacts on all aspects of the healthcare system. The international community must address these effects on health and take necessary measures to prevent or mitigate them, particularly in ensuring the provision of basic and essential healthcare needs for individuals and communities.

Abstract
Background
This study investigated the characteristics of Monson’s sphere in Chinese young adult females with individual normal occlusion to provide a reference for oral rehabilitation in prosthodontic and orthodontic treatments.

Methods
Points at the dental cusps and incisal edges were selected from 51 digital mandibular dental models of Chinese young adult females (aged 18–22 years) with individual normal occlusion. Monson’s spheres were fitted to the selected points based on the least-squares principle and the radii were calculated. The deviation of each selected point from its relative spherical surface was also calculated. The radii and deviations of these points were examined using conventional descriptive statistics and distributions of the most deviated points inside and outside the spheres were analyzed.

Results
The mean radius of Monson’s sphere in Chinese young adult females was 79.60 ± 14.13 mm. The deviation of each selected point from its relative sphere surface was 0.38 ± 0.30 mm. The maximum deviations inside and outside the sphere were 0.93 ± 0.25 mm and 0.95 ± 0.30 mm, respectively. The most deviated points outside the spheres were mainly distributed at the distolingual cusps of the mandibular second permanent molars (31.37%), while those inside the spheres were mainly distributed at the mesiolingual cusps of the mandibular first permanent molars (45.10%).

Conclusions
The radius of Monson’s sphere in Chinese young adult females was smaller than the classic four-inch value suggested by Monson. Deviation was observed from all selected points to their Monson’s sphere surface, with the most deviated points distributed primarily in the molar region.

Published: August 2024

Abstract
Background
Enamel is highly transparent at short wavelength infrared imaging (SWIR) wavelengths allowing the detection of dental decay without the need for ionizing radiation. The purpose of this study was to use SWIR imaging methods including cross polarization optical coherence tomography (CP-OCT), occlusal transillumination (SWIR-OT), proximal transillumination (SWIR-PT), and occlusal reflectance (SWIR-R) to image interproximal lesions in vivo and compare the sensitivity with radiography.

Methods
Participants (n = 30) aged 18–80 each with a radiopositive interproximal lesion scheduled for restoration were enrolled in the study. Studies have shown that the opposing proximal surfaces across the contact will likely also have lesions. SWIR images were acquired of the adjoining teeth at each contact with an interproximal lesion scheduled for restoration. Lesion presence and depth were assessed on each side of the contact for radiography and each SWIR imaging method. Lesions on radiographs and in CP-OCT images were identified by a single examiner while lesions in SWIR images were identified by a contrast threshold via semi-automatic image segmentation.

Results
All SWIR imaging methods had significantly higher sensitivity (P < 0.05) than radiographs for the detection of interproximal lesions on the teeth opposite those restored. CP-OCT and SWIR-R imaging methods had significantly higher sensitivity than the other methods. SWIR imaging methods showed significantly higher lesion contrast than radiography.

Conclusions
SWIR imaging methods can be used to detect interproximal lesions on posterior teeth with higher diagnostic performance than radiographs. CP-OCT appears well suited as a potential gold standard for the detection of interproximal lesions and assessment of their severity in vivo.

Abstract
Background
Ventilation management may differ between COVID–19 ARDS (COVID–ARDS) patients and patients with pre–COVID ARDS (CLASSIC–ARDS); it is uncertain whether associations of ventilation management with outcomes for CLASSIC–ARDS also exist in COVID–ARDS.

Methods
Individual patient data analysis of COVID–ARDS and CLASSIC–ARDS patients in six observational studies of ventilation, four in the COVID–19 pandemic and two pre–pandemic. Descriptive statistics were used to compare epidemiology and ventilation characteristics. The primary endpoint were key ventilation parameters; other outcomes included mortality and ventilator–free days and alive (VFD–60) at day 60.

Results
This analysis included 6702 COVID–ARDS patients and 1415 CLASSIC–ARDS patients. COVID–ARDS patients received lower median VT (6.6 [6.0 to 7.4] vs 7.3 [6.4 to 8.5] ml/kg PBW; p < 0.001) and higher median PEEP (12.0 [10.0 to 14.0] vs 8.0 [6.0 to 10.0] cm H2O; p < 0.001), at lower median ΔP (13.0 [10.0 to 15.0] vs 16.0 [IQR 12.0 to 20.0] cm H2O; p < 0.001) and higher median Crs (33.5 [26.6 to 42.1] vs 28.1 [21.6 to 38.4] mL/cm H2O; p < 0.001). Following multivariable adjustment, higher ΔP had an independent association with higher 60–day mortality and less VFD–60 in both groups. Higher PEEP had an association with less VFD–60, but only in COVID–ARDS patients.

Conclusions
Our findings show important differences in key ventilation parameters and associations thereof with outcomes between COVID–ARDS and CLASSIC–ARDS.

Published: August 2024

Abstract
Background
Pancreatic adenocarcinomas (PAADs) often exhibit a “cold” or immunosuppressive tumor milieu, which is associated with resistance to immune checkpoint blockade therapy; however, the underlying mechanisms are incompletely understood. Here, we aimed to improve our understanding of the molecular mechanisms occurring in the tumor microenvironment and to identify biomarkers, therapeutic targets, and potential drugs to improve PAAD treatment.

Methods
Patients were categorized according to immunologically hot or cold PAAD subtypes with distinct disease outcomes. Cox regression and weighted correlation network analysis were performed to construct a novel gene signature, referred to as ‘Downregulated in hot tumors, Prognostic, and Immune-Related Genes’ (DPIRGs), which was used to develop prognostic models for PAAD via machine learning (ML). The role of DPIRGs in PAAD was comprehensively analyzed, and biomarker genes able to distinguish PAAD immune subtypes and predict prognosis were identified by ML. The expression of biomarkers was verified using public single-cell transcriptomic and proteomic resources. Drug candidates for turning cold tumors hot and corresponding target proteins were identified via molecular docking studies.

Results
Using the DPIRG signature as input data, a combination of survival random forest and partial least squares regression Cox was selected from 137 ML combinations to construct an optimized PAAD prognostic model. The effects and molecular mechanisms of DPIRGs were investigated by analysis of genetic/epigenetic alterations, immune infiltration, pathway enrichment, and miRNA regulation. Biomarkers and potential therapeutic targets, including PLEC, TRPV1, and ITGB4, among others, were identified, and the cell type-specific expression of the biomarkers was validated. Drug candidates, including thalidomide, SB-431542, and bleomycin A2, were identified based on their ability to modulate DPIRG expression favorably.

Conclusions
By combining multiple ML algorithms, we developed a novel prognostic model with excellent performance in PAAD cohorts. ML also proved to be powerful for identifying biomarkers and potential targets for improved PAAD patient stratification and immunotherapy.
