A novel TAp73-inhibitory compound counteracts stemness features of glioblastoma stem cells.

Glioblastoma (GB) is the most common and fatal type of primary malignant brain tumor for which effective therapeutics are still lacking. GB stem cells, with tumor-initiating and self-renewal capacity, are mostly responsible for GB malignancy, representing a crucial target for therapies. The TP73 gene, which is highly expressed in GB, gives rise to the TAp73 isoform, a pleiotropic protein that regulates neural stem cell biology; however, its role in cancer has been highly controversial. We inactivated TP73 in human GB stem cells and revealed that TAp73 is required for their stemness potential, acting as a regulator of the transcriptional stemness signatures, highlighting TAp73 as a possible therapeutic target. As proof of concept, we identified a novel natural compound with TAp73-inhibitory capacity, which was highly effective against GB stem cells. The treatment reduced GB stem cell-invasion capacity and stem features, at least in part by TAp73 repression. Our data are consistent with a novel paradigm in which hijacking of p73-regulated neurodevelopmental programs, including neural stemness, might sustain tumor progression, pointing out TAp73 as a therapeutic strategy for GB.

Detection of caprine paratuberculosis (Johne's disease) in pre- and post-vaccinated herds: morphological diagnosis, lesion grading, and bacterial identification.

Samples from the mesenteric lymph nodes (MS LNs) and ileocecal valves (ICV) of 105 goats, comprising 61 non-vaccinated and 44 vaccinated against Mycobacterium avium subspecies paratuberculosis (MAP), were collected at slaughter from a farm with a confirmed history of paratuberculosis (PTB). These goats had subclinical infections. PTB-compatible lesions in the MS LNs, ICV lamina propria (LP), and Peyer's patches (PPs) were graded separately. Furthermore, the load of acid-fast bacilli was quantified using Ziehl-Neelsen staining (ZN), MAP antigens by immunohistochemistry (IHC), and MAP DNA by PCR targeting the IS900 sequence. Gross PTB-compatible lesions were found in 39% of the goats, with 31.72% vaccinated (V) and 68.29% non-vaccinated (nV). Histopathological lesions induced MAP were observed in 58% of the animals, with 36.07% vaccinated and 63.93% non-vaccinated. The inclusion of histopathology as a diagnostic tool led to a 28% increase in diagnosed cases in MS LNs and 86.05% in ICV. Grade IV granulomas with central mineralization and necrosis were the most common lesions in MS LNs. In the ICV, mild granulomatous enteritis with multifocal foci of epithelioid macrophages was predominant, occurring more frequently in the PPs than in the LP. Furthermore, statistical differences in the presence of histopathological lesions between vaccinated and non-vaccinated goats were noted in MS LNs, ICV LPs, and ICV PPs. Non-vaccinated animals showed higher positivity rates in ZN, IHC, and PCR tests, underscoring the benefits of anti-MAP vaccination in reducing PTB lesions and bacterial load in target organs. Our findings emphasize the necessity of integrating gross and histopathological assessments with various laboratory techniques for accurate morphological and etiological diagnosis of PTB in both vaccinated and non-vaccinated goats with subclinical disease. However, further studies are required to refine sampling protocols for subclinical PTB in goats to enhance the consistency of diagnostic tools.

The impact of acute kidney damage in the community.

BACKGROUND AND HYPOTHESIS: Assess incidence of Acute Kidney Diseas and Disorders (AKD) and Acute Kidney Injury (AKI) episodes and impact on progression of renal dysfunction and risk of all-cause mortality in the community. METHODS: Community of 1 863 731 aged > 23 years with at least two serum creatinine measurements. eGFR was calculated using CKD-EPI formula. CKD, AKD and AKI were defined according to the harmonized KDIGO criteria (Lameire 2021). The sCr values and RIFLE scale was used to classify episodes. Progression of renal dysfunction and mortality were evaluated. RESULTS: 56 850 episodes of AKD in 47 972 patients in 4.8 years were identified. AKD incidence of AKD was 3.51 and 12.56/1000 patients/year in non-CKD and CKD, respectively. One AKD episode was observed in 87.3% patients, two in 9.3% and three or more in 3.4%. A second episode was less common in patients without CKD (10.3%) compared to those with CKD (18.4%). Among patients without CKD a total of 43.8% progressed to CKD, and those with previous CKD 63.1% had eGFR decline of > 50%. The risk of progression to CKD was higher in women, older, overweight-obesity and heart failure, as was the risk of eGFR decline > 50% in CKD patients, although the number of AKD episodes was also a risk factor. AKI episodes were observed in 5646 patients with or without CKD. Of these, 12.7% progressed to CKD and of those with pre-existing CKD, 43.2% had an eGFR decline of > 20%. In the toal population mortality within 3 months of detection of AKD episode occurred in 7% patients, and was even higher in patients with AKI, 30.1%. CONCLUSION: Acute elevations in serum creatinine in the community may pose a health risk and contribute to the development of CKD. Identification of therapeutic targets and provision of appropriate follow-up for those who survive an episode is warranted.

The bottlenose dolphin (Tursiops truncatus): A novel model for studying healthy arterial aging.

Endothelial function declines with aging and independently predicts future cardiovascular disease (CVD) events. Diving also impairs endothelial function in humans. Yet, dolphins, being long-lived mammals adapted to diving, undergo repetitive cycles of tissue hypoxia-reoxygenation and disturbed shear stress without manifesting any apparent detrimental effects, as CVD is essentially nonexistent in these animals. Thus, dolphins may be a unique model of healthy arterial aging and may provide insights into strategies for clinical medicine. Emerging evidence shows that the circulating milieu (bioactive factors in the blood) is at least partially responsible for transducing reductions in age-related endothelial function. To assess if dolphins have preserved endothelial function with aging due to a protected circulating milieu, we tested if the serum (pool of the circulating milieu) of bottlenose dolphins (Tursiops truncatus) induces the same arterial aging phenotype as the serum of age-equivalent humans. We incubated conduit arteries from young and old mice with dolphin and human serum and measured endothelial function ex vivo via endothelium-dependent dilation to acetylcholine. While young arteries incubated with serum from mid-life/older adult human serum had lower endothelial function, those incubated with dolphin serum consistently maintained high endothelial function regardless the age of the donor. Thus, studying the arterial health of dolphins could lead to potential novel therapeutic strategies to improve age-related endothelial dysfunction in humans.

Rural-urban differences in emergency medical services bypass routing of stroke in North Carolina.

PURPOSE: Acute stroke is a serious, time-sensitive condition requiring immediate medical attention. Emergency medical services (EMS) routing and direct transport of acute stroke patients to stroke centers improves timely access to care. This study aimed to describe EMS stroke routing and transports by rurality in North Carolina (NC). METHODS: We conducted a retrospective study using existing data on EMS transports of suspected stroke patients in NC in 2019. The primary study outcome was EMS bypass of the nearest hospital for transport to a nonnearest hospital, determined by geographic information systems (GIS) analysis. Incident addresses were geocoded to census tracts and classified as urban, suburban, or rural by Rural-Urban Commuting Area codes. We compared the frequency of bypass and estimated additional transport times by urban, suburban, and rural incident locations. FINDINGS: Of 3666 patients, 1884 (51%) EMS transports bypassed the nearest hospital. Bypass occurred less often for rural EMS incidents (39%) compared to those in urban (57%) and suburban (63%) tracts. The estimated additional transport time for rural bypasses of nonendovascular-capable stroke centers for endovascular-capable stroke centers was a median of 25 min (interquartile range 13-33). CONCLUSIONS: Using GIS analysis, we found nearly half of EMS transports of suspected stroke patients in NC bypassed the nearest hospital, including noncertified hospitals and stroke centers. Bypasses occurred less often in rural areas, though incurred significantly longer transport times, compared to urban areas. These findings are important for regional stroke system planning, especially for improving rural access to acute stroke care.

The influence of vigorous physical exertion on cardiac demand under conditions of daily living among firefighters with elevated blood pressure.

BACKGROUND: Firefighters have a high prevalence of cardiovascular disease. The poor heart health of firefighters is implicated in their increased risk of sudden cardiac death (SCD). Exercise may be protective against SCD partially due to the immediate blood pressure (BP) reductions of 5-8 mmHg following exercise, termed postexercise hypotension (PEH) OBJECTIVES: To examine PEH under ambulatory conditions after a maximal cardiopulmonary exercise test (CPET) among career firefighters METHODS: Firefighters (n = 19) completed a maximal CPET and non-exercise control (CONTROL) in random order on separate non-workdays and left the laboratory instrumented to an ambulatory BP (ABP) monitor. Ambulatory systolic BP (ASBP), diastolic BP (ADBP), and heart rate (AHR) were recorded at hourly intervals over 19hr. The ambulatory rate pressure product (ARPP) was calculated as ASBPxAHRx10-3 at each hourly interval. Repeated measures ANCOVA tested if the ABP, AHR, and ARPP responses differed after CPET vs CONTROL over 19hr RESULTS: Firefighters were middle-aged (39.5 ± 8.9 yr), overweight (29.2 ± 4.0 kg/m2) men with elevated BP (123.1 ± 9.6/79.8 ± 10.4 mmHg), while resting HR (67.7 ± 11.3 bpm) and RPP (8.4 ± 1.7mmHg*bpm*10-3) were in normal ranges. ASBP (16.6 ± 5.7 mmHg) and ADBP (3.1 ± 4.6 mmHg) increased after the CPET vs CONTROL over 19hr (ps<0.01), as did AHR (9.4 ± 7.9 bpm, p = 0.02) and ARPP (2.5 ± 1.1mmHg*bpm*10-3, p < 0.01). CONCLUSIONS: Unexpectedly, the firefighters exhibited postexercise hypertension rather than PEH. The increases in ABP and AHR we observed indicated a sustained increase in cardiac demand. Further investigation is needed to confirm our findings and determine whether the adverse hemodynamic responses we observed contribute to the high prevalence of SCD that firefighters experience on the job.

Survey of severe acute respiratory syndrome coronavirus 2 in captive and free-ranging wildlife from Spain.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), considered a zoonotic agent of wildlife origin, can infect various animal species, including wildlife in free-range and captive environments. Detecting susceptible species and potential reservoirs is crucial for preventing the transmission, spread, genetic evolution, and further emergence of viral variants that are major threats to global health. This study aimed to detect exposure or acute infection by SARS-CoV-2 in 420 animals from 40 different wildlife species, including terrestrial and aquatic mammals, from different regions of Spain during the 2020-2023 coronavirus disease 19 (COVID-19) pandemic. In total, 8/137 animals were positive for SARS-CoV-2 antibodies against the receptor binding domain and/or viral nucleoprotein according to independent ELISAs. However, only one ELISA-positive sample of a captive bottlenose dolphin (Tursiops truncatus) tested positive for SARS-CoV-2 neutralizing antibodies with a low titre (SNT50 38.15) according to a virus neutralization test. Cetaceans are expected to have a high risk of infection with SARS-CoV-2 according to early predictive studies due to the similarity of their angiotensin converting enzyme 2 cell receptor to that of humans. Moreover, of 283 animals analysed for SARS-CoV-2 RNA using RT-qPCR, none tested positive. Our results reinforce the importance of considering cetaceans at risk for SARS-CoV-2 infection and support taking preventive biosecurity measures when interacting with them, especially in the presence of individuals with suspected or confirmed COVID-19. Although most animals in this study tested negative for acute infection or viral exposure, ongoing surveillance of wildlife species and potentially susceptible animals is important to prevent future spillover events and detect potential novel reservoirs.

Ulcerative and pyogranulomatous pododermatitis due to Pseudomonas luteola infection in a domestic ferret (Mustela putorius furo): a case report with literature review of this emerging zoonotic disease in ferrets.

Pseudomonas luteola (P.luteola), formerly called Chryseomonas luteola, is a strict aerobic gram-negative bacillus, 0.8 to 1.0 µm wide and 1.5 to 2.5 µm long, considered an opportunistic pathogen found ubiquitously in humid environments, both in soil and water. It sporadically causes disease in animals and immunosuppressed humans or those subjected to invasive procedures such us peritoneal dialysis or catheterization. In ferrets, this infection was first described in Spain in 2012 and since then, cases have appeared occasionally in Finland, Austria, Australia, France, the United States and also in Spain. This pathogen is considered an emerging zoonotic disease in ferrets, causing respiratory disease, panniculitis, and abscesses due to pyogranulomatous or suppurative inflammation predominantly of the pleura, lung, mediastinum, panniculus or salivary glands, frequently with lethal consequences. The clinical case of a ferret, infected by Pseudomona luteola, presenting with ulcerative suppurative pododermatitis and ipsilateral popliteal purulent lymphadenitis, is described. Together with a complete resolution of the clinical case by means of a non-invasive medical management likely due to the rapid detection, identification, and treatment of the infection.

Lower Urinary Tract Symptoms Correlate with Erectile Dysfunction and Premature Ejaculation but Not with Men's Sexual Activity: Results from a Large Population-Representative Study.

BACKGROUND: Lower urinary tract symptoms (LUTS) contribute to erectile dysfunction (ED) and premature ejaculation (PE). However, only a few studies have been conducted with representative groups of men that had well-balanced demographic characteristics. Thus, we aimed to confirm the effect of LUTS on ED and PE and to analyze the association between LUTS and men's sexual activity in a large representative cohort. In addition, we evaluated the sex-specific and overall quality of life of men who had LUTS with either ED or PE. METHODS: We used the latest census and estimated the sample size to build a group of men representative of the population. LUTS, ED, and PE were evaluated with reliable instruments. Regression models were used to analyze the data. RESULTS: All included men were representative in relation to their age and residential location (n = 3001). ED and PE were more common in men who reported LUTS compared with men who did not have LUTS (p < 0.001). Age, comorbidity, and lifestyle did not affect the negative effect of LUTS on ED or PE (regression coefficients of 0.159 and 0.528 for ED and PE, respectively, p < 0.001). However, regression models did not validate the impact of LUTS on sexual activity, defined by intercourse frequency and number of sexual partners (odds ratio of 0.981, CI 0.961-1.001, p = 0.061). Nevertheless, men with LUTS and either ED or PE had worse quality of sexual life and general quality of life compared with the remaining respondents. CONCLUSION: LUTS worsened ED and PE but had no impact on men's sexual activity. Our findings confirm the recommendations to assess for LUTS in men reporting ED or PE. CLINICAL TRIAL REGISTRATION: The study was registered with ClinicalTrials.gov (NCT05462171).

Blunt Force Trauma in the Canarian Houbara Bustard (Chlamydotis undulata fuertaventurae) Produced by Collision with Overhead Lines.

The mortality of birds resulting from collisions and electrocutions with overhead lines, such as power lines and phone lines, among others, has been implicated in the decline of various avian species globally. Specifically, overhead line collisions pose a significant threat to the conservation of the Canarian houbara bustard (Chlamydotis undulata fuertaventurae), an endangered subspecies endemic to the Canary Islands. This study centers on the postmortem findings of Canarian houbara bustards that have collided with overhead lines, providing insights into the post-collision outcomes for these birds. A complete standardized necropsy of nine Canarian houbara bustards revealed that trauma was the cause of death in all cases. The most notable gross lesions associated with trauma included bone fractures, soft tissue lacerations, hemorrhages, luxations, and hemocoelom. The inguinal area, chest, and wings were the body regions more frequently affected. A histopathology, immunohistochemistry, and entomology analysis confirmed that numerous birds survived the initial trauma. We concluded that when a houbara bustard collides with an overhead line, it frequently survives the initial trauma, with a survival time ranging from minutes to hours. The histopathology, immunohistochemistry, or entomologic analysis may be helpful to approximate the timing interval between trauma and death.

Position statement of the Spanish Society of Paediatric Infectious diseases on the diagnosis and treatment of Mycoplasma pneumoniae infection.

Mycoplasma pneumoniae (M. pneumoniae) is a bacterium with particular characteristics that give rise to a broad clinical spectrum, being respiratory infection the most frequent presentation. Infection by M. pneumoniae occurs in cyclical epidemics, and paediatricians in Spain have noticed an increase in cases since January 2024, establishing hospital registers to collect surveillance data (as it is not a notifiable disease in Spain). The diagnosis of infection by M. pneumoniae is made through serological testing and/or the detection of genetic material by means of polymerase chain reaction (PCR). Neither methods can differentiate between colonization and active infection, so a precise diagnosis is not possible and testing should only be requested in the case of high clinical suspicion. The role of antibiotherapy in infection by M. pneumoniae in its different clinical variants is not well defined. Most infections are self-limiting and mild, and there is insufficient evidence to support the use of antibiotherapy in these cases. Antibiotic treatment is justified in patients with risk factors for the development of severe disease (Down syndrome, anatomical or functional asplenia, immunosuppression), in hospitalized patients with respiratory infection and in patients with moderate or severe extrapulmonary forms. Taking into account aspects concerning the rational use of antimicrobials, the treatment of choice would be clarithromycin, with azithromycin as an alternative, reserving the use of doxycycline and levofloxacin for cases of antimicrobial resistance and/or infections of the central nervous system.

First Evidence of Leishmania infantum Antibodies in Sheep (Ovis aries) from Southern Germany.

In Europe, Leishmania infantum is the most prevalent Leishmania species, and this protozoan is transmitted by phlebotomine sandflies. A recent publication has shown that sheep harbor L. infantum antibodies. This raises questions about the epidemiological role of small ruminants. Therefore, sera from small ruminants located in two southern German federal states, Baden-Wuerttemberg (BW) and Bavaria (BAV), were analyzed with an ELISA to determine the presence of L. infantum antibodies. The species, sex and age (gimmer vs. ewe) were recorded, and a univariate analysis was conducted to determine possible associations. In total, seven sheep flocks (274 sheep/10 goats) from BW and seven sheep flocks (277 sheep/78 goats) from BAV were examined. In BW, four sheep from three flocks tested positive for L. infantum antibodies. In BAV, the same number of positive sheep were detected but in four flocks. The total seropositivity rate in sheep was 1.45%. All goats tested negative. No significant association (p > 0.05) was detected between Leishmania seropositivity and the variables evaluated. Our study reveals the exposure of sheep to L. infantum in a non-endemic area. Further investigation is needed to determine whether sheep can be used as sentinels to identify new phlebotomine habitats and Leishmania risk areas.

Mandibular bone mass density in a medieval population and its relationship with stable isotopes δ13C and δ15N.

The aim of this study was to compare the level of bone mass in digital orthopantomograms in two populations (medieval and current) using two radiomorphometric indexes, and to correlate the mandibular bone mass value, in the medieval mandible population, with stable isotope data δ13C and δ15N. An observational, cross-sectional, and analytical study on mandibles from two diachronic groups, 15 mandibles from the medieval settlement of La Torrecilla (Granada, Spain) and 15 mandibles from current patients at the Faculty of Dentistry of the University of Granada (Spain), matched by age and sex was conducted. The bone mass density was determined using the Mandibular Cortical Width Index (MCW) and the Mandibular Panoramic Index (PMI) in digital panoramic radiographs. In the medieval group, the values of bone mass density were correlated with those of two stable isotopes (δ13C and δ15N). The mean value of MCW in mm in the medieval group was 3.96 ± 0.60 (mean ± standard deviation) and in the current group was 4.02 ± 1.01. The PMI was 0.33 ± 0.06 and 0.35 ± 0.08 in the medieval and current groups respectively, with similar results in both groups (p = 0.820 and p = 0.575). A negative correlation was found between both morphometric indices and the δ15N isotope (rs = 0.56, p = 0.030 and rs = 0.61, p = 0.016, respectively). The bone mass density in mandibles belonging to the two compared populations, determined by two quantitative radiomorphometric indices, is similar. Within the medieval population, there is an inverse correlation between the δ15N value and bone mass density.

Different localization of P2X4 and P2X7 receptors in native mouse lung - lack of evidence for a direct P2X4-P2X7 receptor interaction.

Introduction: P2X receptors are a family of homo- and heterotrimeric cation channels gated by extracellular ATP. The P2X4 and P2X7 subunits show overlapping expression patterns and have been involved in similar physiological processes, such as pain and inflammation as well as various immune cell functions. While formation of P2X2/P2X3 heterotrimers produces a distinct pharmacological phenotype and has been well established, functional identification of a P2X4/P2X7 heteromer has been difficult and evidence for and against a physical association has been found. Most of this evidence stems, however, from in vitro model systems. Methods: Here, we used a P2X7-EGFP BAC transgenic mouse model as well as P2X4 and P2X7 knock-out mice to re-investigate a P2X4-P2X7 interaction in mouse lung by biochemical and immunohistochemical experiments as well as quantitative expression analysis. Results: No detectable amounts of P2X4 could be co-purified from mouse lung via P2X7-EGFP. In agreement with these findings, immuno-histochemical analysis using a P2X7-specific nanobody revealed only limited overlap in the cellular and subcellular localizations of P2X4 and P2X7 in both the native lung tissue and primary cells. Comparison of P2X4 and P2X7 transcript and protein levels in the respective gene-deficient and wild type mice showed no mutual interrelation between their expression levels in whole lungs. However, a significantly reduced P2rx7 expression was found in alveolar macrophages of P2rx4 -/- mice. Discussion: In summary, our detailed analysis of the cellular and subcellular P2X4 and P2X7 localization and expression does not support a physiologically relevant direct association of P2X4 and P2X7 subunits or receptors in vivo.

Exploring Iberian ham triacylglycerols: Unraveling the influence of growing area, season, breed, and feeding patterns through innovative compositional data analysis.

This research examined the triacylglycerol composition of Iberian pig hams from Sevilla province, focusing on the influence of growing area, season, breed, age, montanera duration, and feeding types. Compositional data analysis (CoDA) tools and standard multivariate statistics were employed to analyse the original and CoDa-transformed data. ANOVA (ilr) and ANCOVA (log ratios) revealed significant effects of season, feeding type, and towns on triacylglycerol profiles, while montanera showed limited or no effect. Breeds and age were deemed irrelevant. Various discriminant analysis (DA) methods consistently distinguished samples from the 2004/2005 season and the cebo feeding type but struggled with other distinctions. PLS-R analysis indicated that bellota feeding was associated with triacylglycerols rich in oleic acid, while cebo was predominantly linked to those containing palmitic and stearic acids. The study challenges traditional assumptions about the effects of montanera, breeds, and age on Iberian pig hams and highlights the need for further investigation.

Infections of cardiac implantable electronic devices and how to improve transvenous lead extraction by the virtual reality.

Introduction: Infections in cardiac implantable electronic devices (CIED) are increasing over time and associated with substantially mortality and healthcare costs. The best approach is the complete removal of the system by transvenous lead extraction (TLE). However, when leads are more than 10 years old, this technique requires considerable expertise and failures with the result of abandoned leads or serious complications may occur. The aim of this study is to describe our experience using virtual and mixed reality in the preoperative planning of complex cases. Patients and methods: Consecutive patients from a referral centre with CIED infections in which TLE was judged difficult. Synchronized computed tomography (CT) scan images were processed and transferred to a fully immersive virtual reality room and also to the operative room (mixed reality) for better guidance during the extracting procedure. Results: Ten patients (seven with local and three with systemic infections) were preoperative evaluated. Processed images and virtual reality showed intense adherences of the leads to the veins, right ventricle, and right atrium endocardium and between them that preclude a difficult extraction and required a carefully planning and sometimes a different technical approach. The anticipated difficulty was confirmed by the higher times of fluoroscopy. All leads were extracted and no complications were registered. Conclusions: Preoperative planning is essential for evaluation of TLE difficulty and prevention of unexpected situations. Virtual reality seems an estimable aid for operators in planning difficult cases and also an excellent tool for teaching.

Standards of care and educational gaps in adult cystic fibrosis units: a European Respiratory Society survey.

Background: Significant progress in the field of cystic fibrosis (CF) has substantially extended the life expectancy of patients with CF (pwCF). Consequently, the population of adult pwCF has outnumbered paediatric patients in most developed countries. Ageing is a new factor that can contribute to disease complexity and can require adaptation of CF units. Therefore, the necessity for standardised, specialised and multidisciplinary care is imperative. Concerns arise regarding the adequacy of current healthcare, therapeutic and educational offerings. Methods: To address these concerns, a multinational survey was conducted to assess the current state of care in specialised multidisciplinary adult and paediatric CF units and identify areas for improvement. Responses were collected from 44 centres providing regular care to CF patients. Results: The survey unveiled considerable disparities in the availability of critical resources, including diagnostic access, supplementary testing, treatment modalities, transplant and transition programmes, and healthcare professionals' training. Conclusion: This study underscores the urgent need to standardise care across these centres in order to minimise disparities in terms of available resources and training with a particular emphasis on adult pwCF who are becoming more numerous and showing different needs with ageing. The changing landscape of CF in adulthood will require constant monitoring to ensure proper adaptation of the current model of care.

Understanding consumer food choices & promotion of healthy and sustainable Mediterranean diet and lifestyle in children and adolescents through behavioural change actions: the DELICIOUS project.

Over the last decades, the abandonment of traditional dietary patterns, such as the Mediterranean diet, represents an important threat for human health and environmental safeguard. The DELICIOUS project aims to promote healthy lifestyles among children and adolescents by implementing activities and tools to increase the adherence to the Mediterranean Diet with an attention to the environmental impacts of the diet. This study protocol describes the DELICIOUS project as a single-arm, uncontrolled behavioural intervention providing formal and non-formal education activities, development of new snacks and recipe reformulation, web/mobile app development, and physical activities to school children and adolescents in five European countries. The project aims to increase awareness of the nutritional benefits and the sustainability aspects of the Mediterranean Diet and to promote consumers' empowerment through an online platform for sustainable and healthy meal planning in the school canteen.

Metastatic pancreatic and lung cancer patient in complete remission following immunotherapy: A case report and review of literature.

BACKGROUND: Metastatic pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy with dispiriting survival data. Immunotherapy is a promising approach to many cancer types, but achieves poor outcomes in advanced PDAC due to its immunosuppressive tumor microenvironment. We describe a case of metastatic PDAC effectively treated with pembrolizumab. CASE SUMMARY: We report the case of a 67-year-old woman with unresectable locally advanced PDAC, treated with gemcitabine plus nab-paclitaxel followed by radiotherapy plus capecitabine. At nine months, pancreatic tumor progression was observed at the level of the hepatic hilum with the appearance of a new pulmonary nodule suggestive of a second primary, confirmed by left lung biopsy. Systemic immunotherapy was then initiated with pembrolizumab, an immune checkpoint inhibitor targeting programmed cell death protein-1 that covers the two tumor types. The patient showed a complete metabolic response that was maintained throughout the treatment. The patient continues to be disease-free at 5.6 years since the start of immunotherapy. CONCLUSION: These results suggest that the administration of pembrolizumab after chemoradiotherapy has a beneficial effect in patients with metastatic PDAC. To our knowledge, this is the first reported case of a patient with metastatic PDAC and metastatic lung cancer showing such a long-lasting complete response after pembrolizumab treatment without curative surgery. Further studies are required to determine biomarkers that identify PDAC patients most likely to benefit from this immunotherapy.

Effects of a Training Course for Andalusian Podiatrists on Antibiotic Management in Ingrown Toenail Infections: A Pilot Study.

BACKGROUND: The use of antibiotics (ABs) for the prevention and management of infections has been widespread for decades and, at this time, AB resistance is a global health crisis. The available evidence highlights the need to reduce the prophylactic and therapeutic use of ABs to avoid associated risks. METHODS: A preliminary study with a total sample of 56 Andalusian (Spain) podiatrists was surveyed. The purpose of this study was to identify whether there were changes in prescription habits from a situation before a subsequent training course on AB indications for the management of infections associated with ingrown toenails. An ad hoc questionnaire of 15 items related to therapeutic and prophylactic prescriptions of ABs was developed for this purpose, and the evaluation was carried out before and after the training course. RESULTS: The responses obtained before and after training were compared. The training activity led to improvements in the prescription habits of the participants, producing significant changes in the prescription pattern of the professionals in 10 of the 15 items. CONCLUSIONS: The results of this preliminary study show that the podiatrists surveyed improved the rational use of systemic AB therapy in ingrown toenails infections.
