Effects of Age, Period, and Cohort on the Incidence of Psoriasis in Spain: A 30-year Review (1990­2019).

AIM: This study aimed to investigate the effects of age, period, and cohort on the incidence of psoriasis in Spain from 1990 through 2019 using the Global Burden of Disease (GBD) database and age-period-cohort (A-P-C) analysis. METHODS: We conducted an ecological trend study to analyze the incidence rates of psoriasis in Spain from 1990 through 2019. Joinpoint software and National Cancer Institute A-P-C tools were used to identify trends and assess the effects of age, period, and cohort. RESULTS: From 1990 through 2019, an estimated 2.99 million cases of psoriasis were diagnosed in Spain, with a mean annual increase of 0.49%. Significant decreases in age-standardized incidence rates (ASIR) were reported for both sexes, with women consistently maintaining a slightly higher ASIR. Joinpoint analysis revealed multiple turning points in the downward trend, indicating periods of stabilization. A-P-C analysis demonstrated significant declines in both net (overall trend) and local drift (age-specific trends), indicating a broad decrease in the incidence of psoriasis across most age groups. While the risk of psoriasis increased with age, peaking in the 50-54 age group, it declined thereafter. Furthermore, the analysis revealed a continuous decline in risk from 1990 through 2019 for both sexes, with individuals born in the early 21st century exhibiting a significantly lower risk vs those born in the early 20th century. CONCLUSION: This study observed a slight decline in the reported psoriasis ASIR in Spain, potentially due to reduced exposure to risk factors. However, limitations in data and the complexity of factors influencing the incidence of psoriasis require further research.

Investigating mechanical properties of 3D printed polylactic acid / poly-3-hydroxybutyrate composites. Compressive and fatigue performance.

The 3D printing technique known as Material Extrusion (MEX) was initially employed for prototyping, but it has evolved to fit applications in mechanical and biomedical industries. Polylactic acid (PLA) stands out as a commonly used polymer for manufacture pieces by MEX, due to its good properties and organic origins. Pursuing renewable and biodegradable thermoplastics has led to the development materials such as composite of PLA with wood fibers and blends with poly-3-hydroxybutyrate (PHB). This study aims to characterize the effect of the most relevant printing parameters on the mechanical properties of a PLA/PHB blend, motivated by the interest to facilitate the use of this type of materials in industrial applications. To achieve it, compressive and fatigue tests were carried out, comparing the results with those obtained in previous studies for pure PLA and PLA-wood composite. Results show that the compressive behavior of PLA/PHB is influenced by the layer height, nozzle diameter and fill density. Its fatigue behavior is mainly determined by the nozzle diameter and the fill density. Moreover, the mechanical performance of PLA/PHB (Young's Modulus of 1.67 GPa, yield Strength of 33.8 MPa and maximum fatigue life of 9711 cycles) is inferior compared to pure PLA and PLA-wood composite. Despite the increase in the biodegradability that PHB introduces into PLA, the findings of this study reveal that there is statistically evidence that it can also hinder the mechanical performance of the base material.

Electrochemical, gravimetric and surface studies of Phalaris canariensis oil extract as corrosion inhibitor for 316 L type stainless steel in H2O-LiCl mixtures.

The corrosion inhibition action of Phalaris canariensis extract on 316 L stainless steel in the H2O-35 (wt%) LiCl mixture at different temperatures has been evaluated with the aid of weight loss, potentiodynamic polarization curves, linear polarization resistance and electrochemical impedance spectroscopy tests. These studies were complemented by Fourier Transformed Infrared spectroscopy, FTIR, gas/mass chromatography analytical techniques and detailed scanning electronic microscopy studies. Results have indicated that Phalaris canariensis extract is an efficient inhibitor, with an efficiency that increases with its concentration, but it decreases as the temperature increases. Phalaris canariensis extract is physically adsorbed onto stainless steel according to a Temkin type of adsorption isotherm. Phalaris canariensis extract affected both anodic and cathodic electrochemical reactions with a stronger effect on the anodic ones, acting, thus, as a mixed type of inhibitor. Main compounds contained in the Phalaris canariensis extract were palmitic and oleic acids, responsible for its inhibitory properties.

Viral diarrheas - newer advances in diagnosis and management.

PURPOSE OF REVIEW: Viruses are the most common etiological agents of diarrhea in children. Despite rotavirus vaccine introduction, rotavirus remains as the leading cause of death globally, followed by norovirus, which represents a diagnostic challenge. Here, we describe new advances in the diagnosis and management of viral diarrheas. RECENT FINDINGS: Although immunoassays are widely used for their fast turnaround time and low cost, molecular techniques have become the most reliable diagnostic method due to their high sensitivity and capacity to analyze multiple pathogens in gastrointestinal panels. Isothermal nucleic acid amplification assays (LAMP and RPA) are promising techniques since they do not require sophisticated equipment and can be used as point-of-care testing. CRISPR/Cas nucleic acid detection systems are new diagnostic methods with great potential. Several recent published articles describe the role of human intestinal enteroids to characterize norovirus infection, to test new drugs, and for vaccine development. The interaction between the human gut microbiota and gastrointestinal viral infections has been extensively reviewed and offers some innovative mechanisms for therapeutic and preventive measures. SUMMARY: Although important advances have been made, more research is needed to address remaining challenges and further improve diagnostic capabilities and better management strategies for this critical infectious disease.

A 5-year study of bloodstream infections caused by carbapenemase-producing Gram-negative bacilli in southern Spain.

OBJECTIVE: The aim of this study was to evaluate the microbiological epidemiology of carbapenemase-producing Gram-negative bacilli (CPGNB) isolated from blood during a 5-year period. METHODS: A total of 80 isolates from 78 patients were finally included; fifty-five (70.5%) were men and the mean age was 60 years. Detection of carbapenemase production was performed by immunocromatography (IC) and polymerase chain reaction (PCR). Genotyping was carried-out by pulsedfield gel electrophoresis (PFGE) and multi-locus sequence typing (MLST), and characterization of carbapenemase-producing isolates was performed by whole genome sequencing (WGS). RESULTS: The main microorganisms isolated were K. pneumoniae (29.4%), E. cloacae (28.2%), A. baumannii (17.9%) and P. aeruginosa (15.3%). Overall, the most common carbapenemase in Enterobacterales was OXA-48 group (57.7%). The most common carbapenemase in non-fermenting bacilli was OXA-23 (60.8%). The most common ST in K. pneumoniae producing OXA-48 types was ST45 and in E. cloacae ST114, while in E. cloacae producing VIM types was ST78. In OXA-23 types, the most common clone in A. baumannii was ST2, whereas in P. aeruginosa producing IMP types was ST253. CONCLUSIONS: There was an increase in cases recorded in the years of highest incidence and severity of the SARS-CoV-2 pandemic, with a significant number of cases in patients admitted to the ICU. All bacteremias caused by A. baumannii were caused by the same clone, and 12 of the 14 cases caused by A. baumannii were part of outbreaks in the ICU.

Validation of Checklists and Evaluation of Clinical Skills in Cases of Abdominal Pain With Simulation in Formative, Objective, Structured Clinical Examination With Audiovisual Content in Third-Year Medical Students' Surgical Clerkship.

OBJECTIVES: The objective of this study was to develop and validate 6 checklists for evaluating abdominal pain in clinical simulation scenarios; to assess student competencies in managing 6 clinical cases using OSCE, based on faculty evaluations; and to analyze discrepancies between faculty and student evaluations. DESIGN: A practical workshop was designed to address 6 clinical scenarios of abdominal surgical conditions. Four scenarios employed medium fidelity simulators, while 2 scenarios employed standardized patient methodology. Prior to the workshop, students received theoretical audiovisual material. At the conclusion of the workshop, students were evaluated using checklists that assessed communication, privacy, anamnesis, and technical skills. Ten workshops were conducted over 3 years, using the OSCE (Objective Structured Clinical Examination) format for evaluation. SETTING: In the statistical analysis, t-Student tests or ANOVA were employed to ascertain whether there were any significant differences between the groups. In the process of validating checklists for clinical scenarios, 6 experts were asked to evaluate each item on a scale of 1 to 9. To assess the degree of agreement among experts, the intraclass correlation coefficient (ICC) was employed. PARTICIPANTS: The study involved a total of 670 third-year medical students from the University of Murcia (UMU), Spain, who participated in the subject "Medical-Surgical Skills." RESULTS: High levels of appropriateness were observed for the checklist items, with mean scores above 7.5 points, as well as high levels of inter-expert agreement. Students obtained a mean score of 8 points in the evaluation of each clinical scenario. No significant differences were found between faculty and student scores (p < 0.05). CONCLUSIONS: The learning method focused on clinical scenarios of abdominal surgical diseases effectively enhanced the clinical skills of third-year medical students. It used pre-existing audiovisual materials, hands-on workshops with medium-fidelity simulators, and standardized patients. Consistent evaluations from students and faculty confirmed the efficacy of these strategies.

Trastuzumab deruxtecan in patients with previously treated HER2-low advanced breast cancer and active brain metastases: the DEBBRAH trial.

BACKGROUND: Trastuzumab deruxtecan (T-DXd) is approved for human epidermal growth factor receptor 2 (HER2)-positive and HER2-low advanced breast cancer (ABC). T-DXd has shown encouraging intracranial activity in HER2-positive ABC patients with stable or active brain metastases (BMs); however, its efficacy in patients with HER2-low ABC with BMs is not well established yet. METHODS: DEBBRAH is a single-arm, five-cohort, phase II study evaluating T-DXd in patients with central nervous system involvement from HER2-positive and HER2-low ABC. Here, we report results from patients with heavily pretreated HER2-low ABC and active BMs, enrolled in cohorts 2 (n = 6, asymptomatic untreated BMs) and 4 (n = 6, progressing BMs after local therapy). Patients received 5.4 mg/kg T-DXd intravenously once every 21 days. The primary endpoint was intracranial objective response rate per Response Assessment in Neuro-Oncology Brain Metastases (RANO-BM) for both cohorts. RESULTS: Intracranial objective response rate per RANO-BM was 50.0% [3/6 patients; 95% confidence interval (CI) 11.8% to 88.2%] and 33.3% [2/6 patients; 95% CI 4.3% to 77.7%; P = 0.033 (one-sided)] in cohorts 2 and 4, respectively. All responders had partial responses. Median time to intracranial response was 2.3 months (range, 1.5-4.0 months) and median duration of intracranial response was 7.2 months (range, 2.8-16.8 months). Median progression-free survival per RECIST v.1.1. was 5.4 months (95% CI 4.1-10.0 months). Treatment-emergent adverse events occurred in all patients included (16.7% grade 3). Three patients (25.0%) had grade 1 interstitial lung disease/pneumonitis. CONCLUSIONS: T-DXd demonstrated promising intracranial activity in pretreated HER2-low ABC patients with active BMs. Further studies are needed to validate these results in larger cohorts. This trial is registered with ClinicalTrials.gov, NCT04420598.

Valproic acid could help in the fight against COVID-19: A case-control study.

OBJECTIVE: There is early evidence about Valproic acid (VPA) antiviral effect. Our aim was to investigate the incidence and severity of SARS-CoV-2 infection in VPA users as compared with the general population. MATERIAL AND METHODS: A case-control study nested within a cohort, carried out between March 1 and December 17, 2020. Retrospectively, we identified confirmed SARS-CoV-2 infection patients exposed to VPA in our health department (defined as case). We ascertained VPA regimen (all the time (AT) (292 days) or at least 20% of the study period (notAT) (≥58 days) and if VPA levels were in therapeutic range (ATR) (50-100mcg/mL) in the last 24 months. We calculated the cumulative incidence of SARS-CoV-2 infection and hospital admission in the cases, comparing it with the general unexposed VPA population (controls). RESULTS: During the study period, 6183 PCR+ were detected among 281,035 inhabitants, of these, 746 were hospitalized. 691 patients were on VPA notAT and 628 (90.1%) AT. The indication for VPA use was epilepsy in 54.9%. The incidence of PCR+ was 1.736% (OR 0.785 (95%CI 0.443-1.390) and 1.910% (OR 0.865 (95%CI 0.488-1.533), on VPA notAT and VPA AT patients, respectively vs. 2.201% in people without VPA regimen. Those patients with VPA ATR had a lower risk of PCR + (OR 0.233 (95%CI 0.057-0.951) notAT; OR 0.218 (95%CI 0.053-0.890) AT). Hospital admission incidence was lower in patient on VPA (OR was 0.543 (95% CI 0.076-3.871). CONCLUSION: Patients with VPA within the therapeutic range had a reduction of SARS-Cov-2 infection incidence greater than 75%. There is a downward trend in the risk of COVID-19 admission by SARS-CoV-2 in patients on VPA therapy. These findings warrant further investigation.

Early PSA-NCAM reduction in the dentate gyrus and impaired plasticity in the Alzheimer´s disease 3xTg-mice model.

Neurodegenerative diseases such as Alzheimer´s (AD) and physiological ageing are characterized by a decline in neurogenesis and in the polysialylated isoforms of neural cell adhesion molecule (PSA-NCAM) expression within the hippocampus and specifically in the dentate gyrus (DG). In the 3xTG-AD mouse model, which mimics the human disease in both pathological and behavioral features, this decline in PSA-NCAM is associated with the presence of Aß plaques at 9 months and Tau tangles at 12-15 months. In this work we studied the presence of PSA-NCAM at early ages (1-6 months) in the same model. Our results demonstrated that even as early as the first month of age there is a strong decrease in PSA-NCAM dendritic tree mainly altering the molecular layer (MolL) coverage affecting the synaptic plasticity and furthermore confirmed by the reduction of PSA-NCAM area density (Sv) in the 3xTG-AD. Similar and more marked early changes were seen during aging in both NTG and 3xTg-AD animals. Our results demonstrate for the first time a precipitate decrease of PSA-NCAM cells at such very early phases of the disease. This result suggests an early effect of the disease in the progression of immature and pluripotent cells resulting in an ulterior and early diminution of neurogenesis and therefore an impaired hippocampal cellular and synaptic plasticity.

Basic action protocol for the outpatient management of chronic heart failure of the Spanish Society of Internal Medicine.

Chronic heart failure (CHF) represents a challenge for the healthy system due to its high prevalence, high burden of morbidity and mortality, and high consumption of health resources. To address this problem, it is necessary to develop efficient management strategies that include both hospital care and outpatient care. The primary objective is to stabilize the patient and prevent decompensation, with the consequent improvement in quality of life, reduction in hospital admissions and emergency department care, and, consequently, reduction in healthcare costs. In this context, the heart failure and atrial fibrilation working group of the Spanish Society of Internal Medicine has developed a protocol for the management of outpatient CHF, that addresses, from the perspective of Internal medicine, all the problems suffered by the patient with CHF. This protocol aims to optimize pharmacological treatment, control cardiovascular risk factors and various comorbidities, educate the patient and their environment about the disease, promote adherence to treatment and stablish follow-up adapted to their condition.

Multi-omics analysis of antiviral interactions of Elizabethkingia anophelis and Zika virus.

The microbial communities residing in the mosquito midgut play a key role in determining the outcome of mosquito pathogen infection. Elizabethkingia anophelis, originally isolated from the midgut of Anopheles gambiae possess a broad-spectrum antiviral phenotype, yet a gap in knowledge regarding the mechanistic basis of its interaction with viruses exists. The current study aims to identify pathways and genetic factors linked to E. anophelis antiviral activity. The understanding of E. anophelis antiviral mechanism could lead to novel transmission barrier tools to prevent arboviral outbreaks. We utilized a non-targeted multi-omics approach, analyzing extracellular lipids, proteins, metabolites of culture supernatants coinfected with ZIKV and E. anophelis. We observed a significant decrease in arginine and phenylalanine levels, metabolites that are essential for viral replication and progression of viral infection. This study provides insights into the molecular basis of E. anophelis antiviral phenotype. The findings lay a foundation for in-depth mechanistic studies.

Imaging findings of the postoperative chest: What the radiologist should know.

Thoracic surgical procedures are increasing in recent years, and there are different types of lung resections. Postsurgical complications vary depending on the type of resection and the time elapsed, with imaging techniques being key in the postoperative follow-up. Multidisciplinary management of these patients throughout the perioperative period is essential to ensure an optimal surgical outcome. This pictorial review will review the different thoracic surgical techniques, normal postoperative findings and postsurgical complications.

Mucosal associated invariant T cells: Powerhouses of the lung.

The lungs face constant environmental challenges from harmless molecules, airborne pathogens and harmful agents that can damage the tissue. The lungs' immune system includes numerous tissue-resident lymphocytes that contribute to maintain tissue homeostasis and to the early initiation of immune responses. Amongst tissue-resident lymphocytes, Mucosal Associated Invariant T (MAIT) cells are present in human and murine lungs and emerging evidence supports their contribution to immune responses during infections, chronic inflammatory disorders and cancer. This review explores the mechanisms underpinning MAIT cell functions in the airways, their impact on lung immunity and the potential for targeting pulmonary MAIT cells in a therapeutic context.

Effects of Age, Period, and Cohort on the Incidence of Psoriasis in Spain: A 30-year Review (1990-2019).

AIM: This study aimed to investigate the effects of age, period, and cohort on the incidence of psoriasis in Spain from 1990 through 2019 using the Global Burden of Disease (GBD) database and age-period-cohort (A-P-C) analysis. METHODS: We conducted an ecological trend study to analyze the incidence rates of psoriasis in Spain from 1990 through 2019. Joinpoint Regression Program, Version 5.0.2 - May 2023; Surveillance Research Program, National Cancer Institute and National Cancer Institute A-P-C tools were used to identify trends and assess the effects of age, period, and cohort. RESULTS: From 1990 through 2019, an estimated 2.99 million cases of psoriasis were diagnosed in Spain, with a mean annual increase of 0.49%. Significant decreases in age-standardized incidence rates (ASIR) were reported for both sexes, with women consistently maintaining a slightly higher ASIR. Joinpoint analysis revealed multiple turning points in the downward trend, indicating periods of stabilization. A-P-C analysis demonstrated significant declines in both net (overall trend) and local drift (age-specific trends), indicating a broad decrease in the incidence of psoriasis across most age groups. While the risk of psoriasis increased with age, peaking in the 50-54 age group, it declined thereafter. Furthermore, the analysis revealed a continuous decline in risk from 1990 through 2019 for both sexes, with individuals born in the early 21st century exhibiting a significantly lower risk vs those born in the early 20th century. CONCLUSION: This study observed a slight decline in the reported psoriasis ASIR in Spain, potentially due to reduced exposure to risk factors. However, limitations in data and the complexity of factors influencing the incidence of psoriasis require further research.

Preventing biofouling in microalgal photobioreactors.

Photobioreactors (PBRs) are used to grow the light-requiring microalgae in diverse commercial processes. Often, they are operated as continuous culture over months period. However, with time, biofouling layer develops on the inner surfaces of their walls. The fouling layer formation deteriorates the PBR performance as foulants reduce light penetration in it. Light is essential for photosynthetic cultures, and a deterioration in lighting adversely impacts algae growth and biomass productivity. Fouling requires a frequent shutdown to clean the PBR and add to the environmental impact of the operation by generating many wastewaters contaminated with the cleaning chemicals. Antibiofouling coatings could be used to modify the surfaces of existing and future PBRs. Therefore, transparent and non-toxic fouling-release coatings, produced using hydrogel technology, could transform the existing PBRs into efficient and enduring microalgae culture systems, requiring only the application of the coating to the inner walls, without additional investments in new PBRs.

Effect of adding PCSK9 inhibitors to lipid-lowering interventions on arterial stiffness: A systematic review and meta-analysis.

BACKGROUND: Atherosclerosis, a leading cause of mortality, necessitates effective management of hypercholesterolemia, specifically elevated low-density lipoprotein cholesterol (LDL-C). The emergence of proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) has revolutionised lipid-lowering. PCSK9i demonstrates substantial LDL-C reduction and cardiovascular benefits, particularly in statin-intolerant or nonresponsive individuals. However, the potential pleiotropic effects of PCSK9i, especially on arterial stiffness, remain a subject of investigation. This systematic review and meta-analysis seek to provide a nuanced understanding of the potential pleiotropic effects of PCSK9i, specifically on arterial health. The primary objective was to analyse the influence of PCSK9i on arterial stiffness, extending beyond traditional lipid-lowering metrics and contributing to a more comprehensive approach to cardiovascular risk reduction. METHODS: A systematic search was conducted across major databases, clinical trial registries and grey literature. Inclusion criteria comprised adults in prospective cohort studies undergoing PCSK9i augmentation in lipid-lowering therapy, with a focus on arterial stiffness measured by pulse wave velocity (PWv). Random-effects meta-analyses, sensitivity analyses and meta-regression models were employed to assess the pooled effect of adding PCSK9i to lipid-lowering interventions on arterial stiffness. RESULTS: Five studies (158 participants) met the inclusion criteria, demonstrating a significant reduction in PWv (mean difference: -2.61 m/s [95% CI: -3.70, -1.52]; ES: -1.62 [95% CI: -2.53, -.71]) upon adding PCSK9i to lipid-lowering interventions. Subgroup analysis and meta-regression models suggested potential sex-based and baseline PWv-dependent variations, emphasising patient-specific characteristics. CONCLUSION: The meta-analysis provides robust evidence that adding PCSK9i to lipid-lowering interventions significantly improves arterial stiffness, indicating broader vascular benefits beyond LDL-C reduction.

Evidence for multi-fragmentation and mass shedding of boulders on rubble-pile binary asteroid system (65803) Didymos.

Asteroids smaller than 10 km are thought to be rubble piles formed from the reaccumulation of fragments produced in the catastrophic disruption of parent bodies. Ground-based observations reveal that some of these asteroids are today binary systems, in which a smaller secondary orbits a larger primary asteroid. However, how these asteroids became binary systems remains unclear. Here, we report the analysis of boulders on the surface of the stony asteroid (65803) Didymos and its moonlet, Dimorphos, from data collected by the NASA DART mission. The size-frequency distribution of boulders larger than 5 m on Dimorphos and larger than 22.8 m on Didymos confirms that both asteroids are piles of fragments produced in the catastrophic disruption of their progenitors. Dimorphos boulders smaller than 5 m have size best-fit by a Weibull distribution, which we attribute to a multi-phase fragmentation process either occurring during coalescence or during surface evolution. The density per km2 of Dimorphos boulders ≥1 m is 2.3x with respect to the one obtained for (101955) Bennu, while it is 3.0x with respect to (162173) Ryugu. Such values increase once Dimorphos boulders ≥5 m are compared with Bennu (3.5x), Ryugu (3.9x) and (25143) Itokawa (5.1x). This is of interest in the context of asteroid studies because it means that contrarily to the single bodies visited so far, binary systems might be affected by subsequential fragmentation processes that largely increase their block density per km2. Direct comparison between the surface distribution and shapes of the boulders on Didymos and Dimorphos suggest that the latter inherited its material from the former. This finding supports the hypothesis that some asteroid binary systems form through the spin up and mass shedding of a fraction of the primary asteroid.

Linking preterm infant gut microbiota to nasograstric enteral feeding tubes: exploring potential interactions and microbial strain transmission.

Introduction: Preterm birth is a growing problem worldwide. Staying at a neonatal intensive care unit (NICU) after birth is critical for the survival of preterm infants whose feeding often requires the use of nasogastric enteral feeding tubes (NEFT). These can be colonized by hospital-associated pathobionts that can access the gut of the preterm infants through this route. Since the gut microbiota is the most impactful factor on maturation of the immune system, any disturbance in this may condition their health. Therefore, the aim of this study is to assess the impact of NEFT-associated microbial communities on the establishment of the gut microbiota in preterm infants. Material and methods: A metataxonomic analysis of fecal and NEFT-related samples obtained during the first 2 weeks of life of preterm infants was performed. The potential sharing of strains isolated from the same set of samples of bacterial species involved in NICU's outbreaks, was assessed by Random Amplification of Polymorphic DNA (RAPD) genotyping. Results: In the samples taken 48 h after birth (NEFT-1 and Me/F1), Staphylococcus spp. was the most abundant genera (62% and 14%, respectively) and it was latter displaced to 5.5% and 0.45%, respectively by Enterobacteriaceae. Significant differences in beta diversity were detected in NEFT and fecal samples taken at day 17 after birth (NEFT-3 and F3) (p = 0.003 and p = 0.024, respectively). Significant positive correlations were found between the most relevant genera detected in NEFT-3 and F3. 28% of the patients shared at least one RAPD-PCR profile in fecal and NEFT samples and 11% of the total profiles were found at least once simultaneously in NEFT and fecal samples from the same patient. Conclusion: The results indicate a parallel bacterial colonization of the gut of preterm neonates and the NEFTs used for feeding, potentially involving strain sharing between these niches. Moreover, the same bacterial RAPD profiles were found in neonates hospitalized in different boxes, suggesting a microbial transference within the NICU environment. This study may assist clinical staff in implementing best practices to mitigate the spread of pathogens that could threaten the health of preterm infants.

[Antihypertensive prescription in type 2 diabetes patients in Andalusia and SEH-LELHA 2022 guidelines: An economic cost evaluation]. / Prescripción de antihipertensivos en personas con diabetes tipo 2 en Andalucía y recomendaciones SEH-LELHA 2022: evaluación del coste y uso.

OBJECTIVE: This study aims to analyze the prescription of antihypertensive drugs in patients with type 2 diabetes (T2D) in Andalusia, comparing it with the SEH-LELHA 2022 guidelines, and to assess the direct cost of these treatments. MATERIALS AND METHODS: A multicentric, cross-sectional, and descriptive study was conducted with 385 T2D patients. Participants were randomly selected from the patient lists of 120 primary care physicians from Andalusia. Inclusion criteria included a diagnosis of T2D and complete clinical records for the year 2022. Demographic data and drug prescription information were collected, with the average cost per patient being calculated. RESULTS: The mean age of the subjects was 70.72 years, with 53.51% being male. A total of 70.9% of the patients were taking antihypertensive drugs, the most common being ACE inhibitors/ARBs (70.9%), diuretics (70.1%), beta-blockers (40.0%), and calcium channel blockers (20.0%). Each patient took an average of 2.46±1.06 antihypertendsive, and fixed association of 2 or more antihypertensive drugs were used by 40.9% of the studied patients. The annual cost per patient was 141.45€/year. CONCLUSIONS: The study reveals strong adherence to the SEH-LELHA 2022 guidelines among physicians in Andalusia regarding the of antihypertensives for T2D patients, with a significant preference for Renin-Angiotensin System blockers, diuretics, and beta-blockers. However, a notable deviation in prescription practices was observed with the frequent choice of doxazosin over spironolactone, despite the latter being the recommended option for resistant hypertension. Although the overall expenditure on antihypertensives is moderate, their cost-effectiveness is enhanced by the efficacy of these treatments in preventing cardiovascular complications.
