Pharmacogenomics (PGx) has emerged as a powerful tool to personalize drug selection and dosing based on a patient’s genetic profile. However, there are a range of challenges that impede uptake in current clinical practice. For example, clinicians often express frustration with commercially available PGx panel tests, which fail to consistently include all key actionable PGx genes (according to the Clinical Pharmacogenetics Implementation Consortium (CPIC), Food and Drug Administration (FDA) PGx guidelines, or The Dutch Pharmacogenetics Working Group (DPWG) guidelines) and instead are too long with clinically unimportant information (unvalidated genotypes). Additionally, the lack of EMR integration, clinician education and awareness of the benefits of PGx impedes uptake. This paper examines key challenges identified in clinical practice and proposes future directions, focusing on limiting PGx reports to essential data, providing point-of-prescription alerts, and establishing reimbursement pathways that encourage adoption. Future directions include leveraging large language models, integrating point-of-prescription alerts and phenoconversion calculators into the electronic medical record, increasing the genomic diversity of PGx study populations, and streamlining coverage by payers.

Background and Objectives: Electronic fetal heart rate monitoring is mandatory for preterm labor. Moderate to late preterm neonates have an increased risk of overall morbidity, neonatal intensive care (NICU) admission, and consequently, medication use. The outcome of preterm neonates > 32 weeks of gestation in relation to three-tiered fetal heart rate (FHR) categorization was analyzed. Materials and Methods: This was a single-center, retrospective case-control study conducted from January 2021 to December 2023. The study included 25 FGR and 131 control cases born from 33 to 36 6/7 gestational weeks. Outcome was defined as the need for assistance after birth in first 15 min of life, respiratory outcome, and first day dopamine use and fresh frozen plasma transfusion. Maternal characteristics as risk factors for non-normal categories within three-tiered FHR categorization were also analyzed. Results: There was no significant difference in neonatal outcome among groups, except significantly lower 1 min APGAR and longer LOS in the FGR group. An increasing category within the three-tiered FHR categorization positively correlated with the need for assistance after birth, respiratory outcome, dopamine use, fresh frozen plasma transfusion, and length of hospital stay. Negative correlations were revealed between the increasing category within the three-tiered FHR categorization and first and fifth minute APGAR scores. Oligohydramnios and male sex were risk factors for non-normal categories within three-tiered FHR categorization. The correlation was tested using the Spearman correlation coefficient. A logistic regression model was employed to identify maternal risk factors for the non-normal category within three-tiered FHR categorization. All differences were statistically significant (p < 0.05). Conclusions: The increasing category within three-tiered FHR categorization may alert neonatologists to be highly suspicious of RDS, respiratory support, dopamine use, and fresh frozen plasma transfusion in neonates born from 33 to 36 6/7 gestational weeks. Oligohydramnios and male sex increase the probability for non-normal categories in the three-tiered FHR categorization. Full article

Background/Objectives: Remote telemedical management (RTM) in heart failure (HF) patients with cardiac implantable electronic devices (CIED) is a reliable approach to follow device-specific and heart failure-related parameters. However, while some positive outcome data is available, results are inconclusive. We aimed to assess the benefits of continuous remote telemonitoring (RTM) compared to the in-person visit (IPV) in reducing all-cause mortality, heart failure hospitalizations (HFH), cardiovascular (CV) deaths, and the occurrence of inappropriate therapy. Methods: The study comprised a systematic review and meta-analysis of randomized controlled trials (RCTs) testing RTM (device-related or other non-invasive telemonitoring systems) vs. IPV for the management of HF patients. The main endpoints were all-cause and CV mortality. Risk of bias and level of evidence were assessed. Hazard ratios (HRs), odds ratios (ORs) and 95% confidence intervals (CI) were calculated. CENTRAL, EMBASE and MEDLINE were searched, and only randomized controlled studies were included. Results: Sixteen RCTs were identified, comprising a total of 11,232 enrolled patients. Seven studies evaluated all-cause mortality, resulting in an OR 0.83 (95% CI 0.72 to 0.96). When CV mortality was assessed, the RTM group showed a significant benefit compared to the IPV group (OR 0.81, 95% CI 0.67 to 0.97). The risk of bias ranged from “low” to “some concerns” for most outcomes, and the certainty was low to moderate depending on the specific outcomes. Conclusions: RTM proved to be superior in reducing all-cause and CV mortality compared to IPV; however, there is a clear need to have standardized alert actions to achieve the mortality benefit.

Quickly designing digital circuits that are both correct and efficient poses significant challenges. Electronics, especially those incorporating sequential logic circuits, are complex to design and test. While Electronic Design Automation (EDA) tools aid designers, they do not fully automate the creation of synthesisable circuits that can be directly translated into hardware. This paper introduces a system that employs Grammatical Evolution (GE) to automatically generate synthesisable Hardware Description Language (HDL) code for the Finite State Machine (FSM) of a Multi-Sequence Detector (MSD). This MSD differs significantly from prior work as it can detect multiple sequences in contrast to the single-sequence detectors discussed in existing literature. Sequence Detectors (SDs) are essential in circuits that detect sequences of specific events to produce timely alerts. The proposed MSD applies to a real-time vending machine scenario, enabling customer selections upon successful payment. However, this technique can evolve any MSD, such as a traffic light control system or a robot navigation system. We examine two parent selection techniques, Tournament Selection (TS) and Lexicase Selection (LS), demonstrating that LS performs better than TS, although both techniques successfully produce synthesisable hardware solutions. Both hand-crafted “Gold” and evolved circuits are synthesised using Generic Process Design Kit (GPDK) technologies at 45 nm, 90 nm, and 180 nm scales, demonstrating their efficacy. Full article

Soil contamination with heavy metals poses a significant risk to human health and ecological systems through multiple exposure pathways: direct ingestion of crops, dermal contact with polluted soil, and bioaccumulation within the food chain. This study analyses eleven composite soils, each collected in triplicate from different sites in Iași County, four of which are designated Natura 2000 protected areas (Mârzești Forest, Plopi Lake—Belcești, Moldova Delta, and Valea lui David). The assessment includes measurements of soil humidity by the gravimetric method, pH, and organic matter content, examined in relation to heavy metal concentrations due to their well-established interdependencies. For heavy metal determination, energy-dispersive X-ray spectroscopy (EDS) using an EDAX system (AMETEK Inc., Berwyn, PA, USA) and X-ray fluorescence spectrometry (XRFS) with a Vanta 4 analyser (Olympus, Waltham, MA, USA) were employed. Additionally, scanning electron microscopy (SEM) with a Quanta 450 microscope (FEI, Thermo Scientific, Hillsboro, OR, USA) was used primarily for informational purposes and to provide a broader perspective. In the case of chromium, 45.45% of the samples exceeded the permissible levels, with concentrations ranging from 106 mg/kg to 186 mg/kg, the highest value being nearly twice the alert threshold. Notably, not all protected areas maintain contaminant levels within safe limits. The sample from the Mârzești Forest protected site revealed considerably raised concentrations of mercury, arsenic, and lead, exceeding the alert thresholds (1 mg/kg—mercury, 15 mg/kg—arsenic, and 50 mg/kg—lead) established through Order no. 756/1997 issued by the Minister of Water, Forests, and Environmental Protection from Romania. On the other hand, the sample from Podu Iloaiei, an area with intensive agricultural activity, shows contamination with mercury and cadmium, highlighting significant anthropogenic pollution. The findings of this study are expected to raise public awareness regarding soil pollution levels, particularly in densely populated regions and protected ecological zones. Moreover, the results provide a scientific basis for policymakers and relevant authorities to implement targeted measures to manage soil contamination and ensure long-term environmental sustainability.

Background: Saudi Arabia is undertaking a comprehensive reform of its healthcare system to improve the efficiency and accessibility of public healthcare services. A key aspect of this initiative is outsourcing outpatient pharmacy services within the public health sector to retail pharmacies through an electronic prescribing platform known as Wasfaty. The National Unified Procurement Company (NUPCO) manages this platform to ensure spending efficiency and patient accessibility to essential medications. However, there has been a lack of research evaluating the adherence of the Wasfaty e-prescribing platform to established best practices for Computerized Provider Order Entry (CPOE), which are commonly used to assess the performance of various ambulatory e-prescribing systems globally. Objective: This study aimed to assess the level of adherence of Wasfaty to best practices for CPOE. Methods: This descriptive cross-sectional single-center study reviewed filled prescriptions through Wasfaty from May 2022 to December 2023. A list of 60 functional features, including but not limited to patient identification and data access, medication selection, alerts, patient education, data transmission and storage, monitoring and renewals, transparency and accountability, and feedback, was utilized to evaluate adherence. The adherence level was categorized into four groups: fully implemented, partially implemented, not implemented, and not applicable. Two pharmacy interns, a clinical pharmacist, and a researcher, reviewed the prescriptions to determine the platform’s adherence to these 60 CPOE features. Results: From May 2022 to December 2023, a total of 1965 prescriptions were filled in retail pharmacies for out-of-stock medications for 1367 patients. These prescriptions included medications for various areas, with the following distribution: gastroenterology (44.10%), cardiology (18.14%), anti-infectives (2.42%), urology (8.85%), dermatology (3.6%), hematology (0.29%), muscle relaxants (0.8%), neurology (19.17%), pulmonology (1.46%), and other categories (1.23%). Of the 60 functional characteristics a CPOE platform should include, only 19 (31.66%) were fully implemented, while 10 (16.66%) were partially implemented. Conclusions: The Wasfaty platform is deficient in several key functional features necessary for e-prescribing, which are essential for ensuring patient safety and enhancing the satisfaction of both prescribers and patients. This study underscores the importance of improving the Wasfaty platform to reduce the risk of adverse drug events. Full article

Background: This article examines the infectious disease surveillance system in the Lombardy region of Italy, with a focus on its response mechanisms to respiratory syndromes. This study aims to describe the alert system and the organizational procedures in place, assessing their effectiveness in managing health crises. Methods: This study is based on the analysis of Lombardy’s regional resolution No. 1125, developed by regional public health experts. Surveillance levels were categorized based on incidence thresholds and healthcare system impacts, establishing specific indicators and activation protocols. Information flows are managed through real-time data portals, enabling the real-time monitoring of COVID-19, influenza, and other infectious respiratory diseases. Results: A multi-level response system was established, with levels ranging from ordinary regimes to critical epidemic activation. Each level includes specific actions, such as resource reallocation, emergency department support, and the suspension of elective procedures. The use of technological tools, such as electronic health records, streamlined reporting processes, and real-time data flow management, has strengthened the region’s response capabilities. Conclusions: This study underscores the value of a structured, multi-level response system for infectious disease management, showing that a unified regional approach improves crisis response efficiency. It suggests that sharing activation indicators and protocols within the scientific community can help harmonize national and international responses to future pandemics. The system, while effective in its current context, may require adaptation for future health challenges. Full article

The aim of the present study was to evaluate the contamination state of the surface soil from 10 parks from Galati, Romania, and the health hazards of the soil. The soil samples, collected in each site from the playing ground and from the edge of the park, were analyzed by using combined Wavelength- (WDXRF) and Energy-Dispersive (EDXRF) X-ray fluorescence techniques. A total number of 27 chemical elements (Ag, Al, As, Ba, Ca, Cd, Cr, Co, Cu, Fe, Hg, K, Mg, Mn, Na, Ni, P, Pb, Rb, Sb, Sc, Sn, Sr, Ti, V, Zn and Zr) were quantified in the urban soils, and the results were compared to the normal and alert values from Romanian legislation for toxic trace elements, as well as with European and world average values of element concentrations. The mineralogical analyses were performed by Scanning Electron Microscopy with Energy-Dispersive X-ray Analysis (SEM-EDX) and the Attenuated Total Reflectance–Fourier Transform Infrared technique (ATR-FTIR). To assess the soil contamination and the impact on human health of the presence of potential toxic elements and heavy metals in the soil, a series of pollution and health risk indices were used. All the results indicated an unpolluted to moderately polluted soil. The soil samples collected from the edge of the parks presented higher values for the specific pollutants, which originated from heavy traffic, such as Cu, Cr, Zn and Pb. The non-carcinogenic and carcinogenic risk to children was assessed using estimated daily intake (EDI) in relation to the pathways whereby pollutants can enter the human body, such as ingestion, dermal contact, inhalation and vaporization. Using the obtained values for EDI, the hazard quotient and hazard index were determined, which strengthen the formerly issued presumption that soil pollution is moderate and, by itself, does not present any threat to children’s health.

Background: Using intelligent monitoring systems can potentially improve the identification and management of ventilator-associated events (VAEs). This single-center retrospective observational study evaluated the impact of implementing intelligent monitoring systems on the clinical outcomes of patients with VAEs in an ICU setting. Method: An intelligent VAE monitoring system was integrated into electronic medical records to continuously collect patient data and alert attending physicians when a ventilated patient met the criteria for a ventilator-associated condition, which was defined as an increase of at least three cm H₂O in positive end expiratory pressure (PEEP), an increase of at least 0.20 in the fraction of inspired oxygen (FiO₂), or the FiO₂ being over baseline for at least two consecutive days. This study covered two phases, consisting of before using the intelligent monitoring system (2021–2022) and during its use (2023–2024). Results: The results showed that patients monitored with the intelligent system experienced earlier VAE detection (4.96 ± 1.86 vs. 7.77 ± 3.35 days, p < 0.001), fewer ventilator-associated condition (VAC) occurrences, and a shorter total duration of VACs. Additionally, the system significantly reduced ventilator days, antibiotic use, and 14-day mortality. Conclusions: Intelligent monitoring systems enhance VAE management, improve clinical outcomes, and provide valuable insights into the future of critical care medicine. Full article

Background/Objectives: Remote monitoring (RM) cardiac implantable electronic devices for adults delivers improved patient outcomes. However, previously used bedside transmitters are not optimal due to deficient patient adherence. The goal of this study was to evaluate the efficacy of RM regarding the connectivity of smartphone app-based solutions, adherence to scheduled automatic follow-ups, and prevalence of alert-based events. Methods: We evaluated the adult heart failure (HF) population with an implanted cardiac resynchronization therapy defibrillator (CRT-D) divided into two arms: with app-based RM (abRM) and without app-based RM (control). Results: A total of 81 patients (median age of 69.0) were included in our study. Sixty-five patients received a CRT-D with abRM functionality, and sixteen did not. Twelve patients had no smartphone, and two provided no consent, resulting in their transfer to the control group. Finally, the abRM arm consisted of 51 patients, while 30 patients were in the control group. The median period of follow-up lasted 12 months. Among abRM patients, 98.0% successfully transmitted their first scheduled follow-up, and 80.4% were continuously monitored. Alert-based events were mainly related to arrhythmic events and device functionality with significantly shorter median times to notification (1 day vs. 101 days; p < 0.0001) in the abRM group. Conclusions: Our study showed a high level of compliance with timely initial transmission and adherence to scheduled remote follow-ups. Patient enrollment eligibility was a major challenge due to the limited accessibility of smartphones in the population. App-based RM demonstrated an accurate notification of events and patient-initiated transmissions in emergencies, regardless of location. Full article

Background/Objectives: Numerous European countries, including Romania, are facing the concern of rapid ageing of their populations. Moreover, Romania’s life expectancy ranks among the lowest in the European Union. In light of this, it is imperative that the assessment of medication-related harm be given national priority in order to secure and enhance pharmacotherapy and the medical act. In this study, we sought to describe and evaluate the under-prescribing practices among the Romanian elderly population. Methods: We conducted a cross-sectional study in urban areas of two counties in Western Romania (Timis and Arad) from November 2017 to February 2019. We collected chronic electronic prescriptions issued for elderly patients (>65 years old) with chronic conditions. The medication was prescribed by generalist or specialist physicians for periods ranging between 30 and 90 days. To assess inappropriate prescribing behaviours, a multidisciplinary team of specialists applied the Screening Tool of Older Persons’ Prescriptions/Screening Tool to Alert to Right Treatment (STOPP/START) v.2 criteria to the collected prescriptions. Results: Within the 1498 prescriptions included in the study, 57% were issued to females, the mean age was 74.1 ± 6.95, and the average number of medicines per prescription was 4.7 ± 1.51. The STOPP criteria most commonly identified were the (1) long treatment duration (23.6%) and (2) prescription of neuroleptics (14.6%) or zopiclone (14.0%) as medications that increase the risk of falls. According to START criteria, the following medicines were under-prescribed: (1) statins (47.4%), (2) beta-blockers (24.5%), (3) antiresorptive therapy (10.0%), and (4) β2-agonists and muscarinic antagonists for chronic obstructive pulmonary disease (COPD) (4.5%). Within our study group, the prevalence of potentially inappropriate medications was 18.58%, whereas the prevalence of potential prescribing omissions was 49.2%. Conclusions: To decrease medication-related harm and morbid-mortality, and to increase the quality of life for elderly people in Romania, immediate actions are needed from national authorities. These actions include reinforcing primary care services, providing periodic training for physicians, implementing medication review services by pharmacists, and utilising electronic health records at their full capacity.

Background/Objectives: The use of eHealth as a monitoring system in people with heart failure (HF) has been shown to be effective in promoting self-care and reducing re-admissions and mortality. The present study develops and evaluates the accessibility and usability of the web app iCardioMonitor HF monitoring system. Methods: This study consisted of two stages. The first stage (co-design) comprised two phases: (1) analysis of the scientific literature and expert opinions and (2) co-design of the iCardioMonitor (web app plus a knowledge-base algorithm) and definition of alert criteria. The second stage (cross-sectional descriptive study) analyzed system accessibility (% of people using the iCardioMonitor and % of parameters recorded) and usability, employing the Spanish version of the System Usability Scale for the Assessment of Electronic Tools. Results: The iCardioMonitor was configured by a web app and an algorithm with the capacity to detect decompensated HF automatically. A total of 45 patients with an average age of 55.8 years (standard deviation [SD] = 10.582) and an average time since diagnosis of 7.1 years (SD = 7.471) participated in the second stage. The percentage of iCardioMonitor use was 83.2%. The average usability score was 77.2 points (SD = 21.828), higher in women than men (89.2; SD = 1.443–76.0; SD = 1.443) (p = 0.004). The usability score was higher the shorter the time since diagnosis (r = 0.402; p = 0.025) and the higher the number of responses (r = 0.377; p = 0.031). Conclusions: The results obtained show that iCardioMonitor is a tool accepted by patients and has obtained a remarkable score on the usability scale. iCardioMonitor was configured by a web app and an algorithm with the capacity to detect decompensated HF automatically.

Introduction: Biofilm is linked through a variety of mechanisms to the pathogenesis of chronic wounds. However, accurate biofilm detection is challenging, demanding highly specialized and technically complex methods rendering it unapplicable for most clinical settings. This study evaluated promising methods of bedside biofilm localization, fluorescence imaging of wound bacterial loads, and biofilm blotting by comparing their performance against validation scanning electron microscopy (SEM). Methods: In this clinical trial, 40 chronic hard-to-heal wounds underwent the following assessments: (1) clinical signs of biofilm (CSB), (2) biofilm blotting, (3) fluorescence imaging for localizing bacterial loads, wound scraping taken for (4) SEM to confirm matrix encased bacteria (biofilm), and (5) PCR (Polymerase Chain Reaction) and NGS (Next Generation Sequencing) to determine absolute bacterial load and species present. We used a combination of SEM and PCR microbiology to calculate the diagnostic accuracy measures of the CSB, biofilm blotting assay, and fluorescence imaging. Results: Study data demonstrate that 62.5% of wounds were identified as biofilm-positive based on SEM and microbiological assessment. By employing this method to determine the gold truth, and thus calculate accuracy measures for all methods, fluorescence imaging demonstrated superior sensitivity (84%) and accuracy (63%) compared to CSB (sensitivity 44% and accuracy 43%) and biofilm blotting (sensitivity 24% and accuracy 40%). Biofilm blotting exhibited the highest specificity (64%), albeit with lower sensitivity and accuracy. Using SEM alone as the validation method slightly altered the results, but all trends held constant. Discussion: This trial provides the first comparative assessment of bedside methods for wound biofilm detection. We report the diagnostic accuracy measures of these more feasibly implementable methods versus laboratory-based SEM. Fluorescence imaging showed the greatest number of true positives (highest sensitivity), which is clinically relevant and provides assurance that no pathogenic bacteria will be missed. It effectively alerted regions of biofilm at the point-of-care with greater accuracy than standard clinical assessment (CSB) or biofilm blotting paper, providing actionable information that will likely translate into enhanced therapeutic approaches and better patient outcomes.

Recent advancements in power electronics have significantly improved photovoltaic (PV) inverters by equipping them with sophisticated monitoring capabilities. These enhancements provide economic advantages by facilitating swift failure detection and lowering monitoring costs. Educating users on the economic repercussions of undetected failures in specific inverter monitoring systems is crucial. This paper introduces a novel metric, “Cost of Detection”, which assesses the financial impact of failures, considering the repair expenses and the “quality” of the monitoring system in place. The study analyzed fifteen inverter monitoring solutions, focusing on the variance in alerts generated by the manufacturers’ standard and extra monitoring features. Employing the Failure Mode and Effects Analysis (FMEA) method, alerts were prioritized based on their importance for two PV system scenarios: a low-power residential system (5 kWp) and a medium-power industrial/commercial system (100 kWp). Lisbon, Rome, and Berlin were chosen as the locations for these systems. The economic impact of system failures is evaluated annually for each capacity and city. Given the differing costs and annual yields, comparing their economic performance over time is essential. This comparison utilizes the Net Present Value (NPV), which estimates an investment’s worth by calculating the present value of all cash flows. The investment assessment includes only the costs of inverters and optimizers, excluding O&M expenses, licenses, and fees. Over five years, a higher NPV signifies a more economically advantageous solution. For residential systems, string inverters with optimizers have the highest NPV, surpassing those without optimizers by 17% across all three cities. The optimal monitoring solution in the industrial/commercial context was a string inverter with one optimizer for every two panels. Here, Rome emerged as the location with the most substantial NPV increase of 50%, followed by Berlin with 33% and Lisbon with 28%. Full article

Infectious diseases manifesting in the form of epidemics or pandemics do not only cause devastating impacts on public health systems but also disrupt the functioning of the socio-economic structure. Further, risks associated with pandemics and epidemics become exacerbated with coincident compound hazards. This study aims to develop a framework that captures key elements and components of epidemic and pandemic preparedness and response systems, focusing on a multi-hazard context. A systematic literature review was used to collect data through peer-reviewed journal articles using three electronic databases, and 17 experts were involved in the validation. Epidemiological surveillance and early detection, risk and vulnerability assessments, preparedness, prediction and decision making, alerts and early warning, preventive strategies, control and mitigation, response, and elimination were identified as key elements associated with epidemic and pandemic preparedness and response systems in a multi-hazard context. All elements appear integrated within three interventional phases: upstream, interface, and downstream. A holistic approach focusing on all interventional phases is required for preparedness and response to pandemics and epidemics to counter their cascading and systemic effects. Further, a paradigm shift in the preparedness for multi-hazards during an epidemic or pandemic is essential due to the multiple challenges posed by concurrent hazards. Full article
