Development of a Global Physical Literacy (GloPL) Action Framework: Study protocol for a consensus process.

BACKGROUND: The holistic concept of physical literacy (PL) has gained growing attention in recent research, policy, and practice. Many important policy documents of the physical activity and educational fields (e.g., Global Action Plan on Physical Activity 2018-2030 by the World Health Organization, UNESCO's Quality Physical Education guidelines for policymakers) have specified PL. However, a clear framework for action is needed, as most initiatives across the world are fragmented, lack a prospective orientation, can benefit from conceptual clarification, and are not linked to effective translation into practice. Therefore, we aim to consensually develop a Global Physical Literacy (GloPL) Action Framework to define goals and principles (asking what is needed) as well as actions and ways (asking how these can be achieved) to move PL forward. MATERIALS AND METHODS: We apply a three-stage group Delphi technique involving three representation groups: (a) geographical representatives to achieve global coverage of perspectives; (b) representatives of special thematic interest reflecting prominent gaps of current PL activities; and (c) representatives of societies from the broad field of physical activity and health to facilitate dissemination. The process will begin with an individual pre-Delphi exercise, in which experts generate initial ideas for the framework, followed by a four-eye document analysis to derive themes for the discussion. Subsequently, the experts will meet face-to-face in three online rounds to discuss and prioritize the themes. Interspersed formal voting with pre-defined agreement thresholds (via descriptive statistics) will inform the inclusion of themes within the final framework. CONCLUSIONS: A global consensus on goals, principles, actions, and ways for the development of PL has the potential to provide a largely accepted roadmap for future activities in research, policy, and practice. The co-production approach will help disseminate the GloPL Action Framework and benefit work in relevant application fields of physical activity and health worldwide.

Focal alveolar hemorrhage following guide-wire progression into the pulmonary arterial circulation during fibrin sheath angioplasty and catheter exchange: Case report.

Central venous catheters are a frequently used vascular access for hemodialysis. Fibrin sheath formation is a common complication and is associated with catheter malfunction. Although fibrin sheath angioplasty with catheter exchange is a frequently employed procedure, it can be associated with mechanical complications. An important technical step in this procedure is progression of the guide-wire into the inferior vena cava. Focal alveolar hemorrhage is a very rare complication of this procedure. We report a case of a 70-year old patient on dual antiplatelet therapy who underwent fibrin sheath angioplasty with guide-wire catheter exchange and experienced focal alveolar hemorrhage presenting as hemoptysis and acute type 1 respiratory failure. Progression of the guide-wire into the pulmonary circulation and antithrombotic therapy played a significant role in the development of this complication. This report aims to call attention to a poorly described and potentially serious yet avoidable complication of fibrin sheath angioplasty with guide-wire catheter exchange.

When Implementing the Presynch-11/Ovsynch Reproductive Management Program, the Fertility of Lactating Dairy Cows Improved When They Received Timed Artificial Insemination Compared with the Inclusion of Estrus Detection.

Artificial insemination 12 h following observed standing estrus is a standard estimate of the fertility levels of cattle. The main objective of this study was to determine if controlling ovarian development with a fertility program could alter the fertility of lactating dairy cows. Lactating dairy cows (n = 1356) 60-66 days in milk (DIM) were randomly assigned to receive timed AI following Presynch-11/Ovsynch (Presynch-11) or a combination of estrus detection and timed AI using the Presynch-11/Ovsynch program (Estrus + TAI). Cows in standing estrus, following the first two cloprostenol sodium (CLO) injections, in the Estrus + TAI group were artificially inseminated using the AM/PM rule. Cows in this group that were not observed in standing estrus received Ovsynch and TAI beginning 11 d after the second CLO injection. Cows in the Presynch-11 group received two injections of 500 µg CLO 14 d apart but were not observed for estrus. The first GnRH (100 µg) of Ovsynch was administered 11 d following the second CLO injection. All cows in the Presynch-11-Ovsynch group received TAI following Ovsynch. Cows in this treatment were then assigned randomly to receive either CLO or dinoprost 7 d following the first GnRH of Ovsynch. The final GnRH of Ovsynch was administered 56 h later and TAI 16 h after the final GnRH. Pregnancies/AI (P/AI) were greater (p < 0.001) for the Presynch-11 group compared with the Estrus + TAI group (45 vs. 31%). Primiparous cows had greater fertility following observed standing estrus compared with multiparous cows. Days in milk at the first AI were greater (p < 0.01) in the Presynch-11 group vs. the Estrus + TAI group (98 vs. 80) but less variable (p < 0.01). The range of DIM at the first AI was 95 to 101 in the Presynch-11 group and 60 to 101 in the Estrus + TAI group. Within the Presynch-11 group, there were no differences in the rate of luteolysis or P/AI for the prostaglandin type at the final PGF2α of Ovsynch. Multiparous cows treated with Presynch-11 had >60% chance of pregnancy compared with multiparous cows receiving AI following standing estrus. In summary, lactating dairy cows receiving timed AI following the Presynch-11/Ovsynch program had improved fertility compared with a group of cows that received AI following standing estrus or, if not observed in estrus, timed AI. This comparison indicated that controlling ovarian development with GnRH and PGF2α positively impacted the fertility of lactating dairy cows.

Integrating sEMG and IMU Sensors in an e-Textile Smart Vest for Forward Posture Monitoring: First Steps.

Currently, the market for wearable devices is expanding, with a growing trend towards the use of these devices for continuous-monitoring applications. Among these, real-time posture monitoring and assessment stands out as a crucial application given the rising prevalence of conditions like forward head posture (FHP). This paper proposes a wearable device that combines the acquisition of electromyographic signals from the cervical region with inertial data from inertial measurement units (IMUs) to assess the occurrence of FHP. To improve electronics integration and wearability, e-textiles are explored for the development of surface electrodes and conductive tracks that connect the different electronic modules. Tensile strength and abrasion tests of 22 samples consisting of textile electrodes and conductive tracks produced with three fiber types (two from Shieldex and one from Imbut) were conducted. Imbut's Elitex fiber outperformed Shieldex's fibers in both tests. The developed surface electromyography (sEMG) acquisition hardware and textile electrodes were also tested and benchmarked against an electromyography (EMG) gold standard in dynamic and isometric conditions, with results showing slightly better root mean square error (RMSE) values (for 4 × 2 textile electrodes (10.02%) in comparison to commercial Ag/AgCl electrodes (11.11%). The posture monitoring module was also validated in terms of joint angle estimation and presented an overall error of 4.77° for a controlled angular velocity of 40°/s as benchmarked against a UR10 robotic arm.

Effectiveness of two scrub methods with different chlorhexidine combinations for surgical field antisepsis in cats.

Objective: Assessing effectiveness of circular (CM) and linear (LM) scrub methods using 3 different combinations of chlorhexidine in surgical field antisepsis in cats. Animals and procedure: Surgical field antisepsis was applied with 2 scrub methods (CM and LM) and 3 different chlorhexidine combinations (A1, A2, and A3) in 51 female cats undergoing ovariectomy. Sterile swabs collected from the surgical field pre- and post-antisepsis were inoculated in the laboratory and colony-forming units (CFU/mL) were quantified. Results: Following the application of antisepsis, the number of positive samples decreased in all groups (P < 0.05) when using both CM and LM, except for CM in the A1 group (P = 0.063). The CFU/mL counts also decreased after antisepsis with both CM and LM in all groups (P < 0.05). A high reduction in CFU/mL counts was observed after antisepsis with both CM and LM in all groups, but no significant differences were observed between the 2 scrub methods (P > 0.05). Conclusion and clinical relevance: Surgical field antisepsis in cats with CM and LM scrub methods, using 2% chlorhexidine combined with 70% ethyl or 70% isopropyl alcohol, or 1% chlorhexidine combined with 70% ethyl alcohol, can effectively reduce the bacterial load on the skin.

Efficacité de deux méthodes de désinfection avec différentes combinaisons de chlorhexidine pour l'antisepsie du champ opératoire chez le chat. Objectif: Évaluation de l'efficacité des méthodes de désinfection par mouvements circulaires (CM) et linéaires (LM) utilisant 3 combinaisons différentes de chlorhexidine dans l'antisepsie du champ opératoire chez le chat. Animaux et procédure: Une antisepsie chirurgicale sur le terrain a été appliquée avec 2 méthodes de désinfection (CM et LM) et 3 combinaisons différentes de chlorhexidine (A1, A2 et A3) chez 51 chattes subissant une ovariectomie. Des écouvillons stériles prélevés sur le champ opératoire avant et après l'antisepsie ont été inoculés en laboratoire et les unités formant des colonies (UFC/mL) ont été quantifiées. Résultats: À la suite de l'application de l'antisepsie, le nombre d'échantillons positifs a diminué dans tous les groupes (P < 0,05) lors de l'utilisation à la fois de CM et de LM, à l'exception du CM dans le groupe A1 (P = 0,063). Le nombre d'UFC/mL a également diminué après antisepsie avec CM et LM dans tous les groupes (P < 0,05). Une forte réduction du nombre d'UFC/mL a été observée après antisepsie avec CM et LM dans tous les groupes, mais aucune différence significative n'a été observée entre les 2 méthodes de désinfection (P > 0,05). Conclusion et pertinence clinique: L'antisepsie chirurgicale sur le terrain chez les chats avec les méthodes de désinfection CM et LM, utilisant 2 % de chlorhexidine combinée à 70 % d'alcool éthylique ou 70 % d'alcool isopropylique, ou 1 % de chlorhexidine combinée à 70 % d'alcool éthylique, peut réduire efficacement la charge bactérienne sur la peau.(Traduit par Dr Serge Messier).

Clinical Difficulties Related to Direct Composite Restorations: A Multinational Survey.

AIMS: Composite materials are widely used in dentistry for direct tooth restorations. However, they are highly sensitive to the working technique employed during the restorative procedure. Even minor procedural errors can have a significant impact on the quality including the longevity of the restoration. Hence the aim of this study was to determine the material preferences and analyse the clinical problems associated with direct composite restorations in a cohort of dentists. METHODS: A 20-item online questionnaire was created in English and administered 1830 general dentists and specialists in 13 countries. The first section of the questionnaire included four questions to elicit demographic data, and the second section comprised 16 questions focused on material preferences for conservative restorations, durability of composite restorations, and the most challenging stages the dentists faced during the composite restorative procedures. RESULTS: Respondents decided most often to use composite materials for the tooth restorations (OR 997.4, 95% CI 233.8-4254.8, P value <.001). Most respondents indicated that the durability of composite restorations was approximately 7 to 10 years (41.5%). Among the factors affecting durability, maintenance of a dry cavity was the most often reported reason (47.1%) and the foremost challenge faced by dentists (61.0%) during the composite restorative procedures. CONCLUSIONS: Our study confirmed that resin-based composites are the most popular material for direct restoration in many countries. Although working with this material is difficult and involves multiple steps, maintaining a dry cavity during bonding, and material application may affect the therapeutic success and durability of these restorations. Clinicians need to be attentive to this issue and be prepared to adapt their decision-making and consider opting for alternative restorative materials, if appropriate.

The Erasmus+ EUMOVE project-a school-based promotion of healthy lifestyles to prevent obesity in European children and adolescents.

The aim of this study was to describe the goals, activities, and methods of EUMOVE project in developing a set of resources targeting both primary and secondary schools that allow the entire educational community to promote healthy lifestyles (HL). The EUMOVE project is an Erasmus+ program based in the Creating Active Schools (CAS) framework. The project lasted 3 years and was developed by 14 academic and non-governmental institutions from Spain, Portugal, France, Italy, and the UK. EUMOVE was divided into three phases. In the first phase, several work packages were carried out aimed to ensure the coordination/management of the project activities. In the second phase, seven educational resources strengthened by rigorous scientific research were developed to promote HL from schools. During the last phase, all the resources were disseminated through scientific seminars, workshops with families and teachers, and the online promotion by the non-governmental institutions of each country. The EUMOVE project developed and promoted a smartphone APP, video/activity repository of physically active lessons, active break virtual platform, learning units, and parent/teachers/school-leaders' guidelines to promote physical activity, active commuting, active school playgrounds, healthy diet, and sleep habits. To our knowledge, EUMOVE is the first European project to provide a set of practical tools based on scientific evidence to help schools or future school-wide interventions implement a paradigm shift based on the CAS framework for the promotion of HL. Future research will need to investigate the implementation, effectiveness, and scalability of this proposal.

Increased susceptibility to kainate-induced seizures in a mouse model of tuberous sclerosis complex: Importance of sex and circadian cycle.

OBJECTIVE: Comorbidity of epilepsy and autism in tuberous sclerosis complex 2 (TSC2) is very frequent, but the link between these conditions is still poorly understood. To study neurological problems related to autism, the scientific community has been using an animal model of TSC2, Tsc2+/- mice. However, it is still unknown whether this model has the propensity to exhibit increased seizure susceptibility. Further, the importance of sex and/or the circadian cycle in this biological process has never been addressed. This research aimed to determine whether male and female Tsc2+/- mice have altered seizure susceptibility at light and dark phases. METHODS: We assessed seizure susceptibility and progression in a Tsc2+/- mouse model using the chemical convulsant kainic acid (KA), a potent agonist of the AMPA/kainate class of glutamate receptors. Both male and female animals at adult age were evaluated during non-active and active periods. Seizure severity was determined by integrating individual scores per mouse according to a modified Racine scale. Locomotor behavior was monitored during control and after KA administration. RESULTS: We found increased seizure susceptibility in Tsc2+/- mice with a significant influence of sex and circadian cycle on seizure onset, progression, and behavioral outcomes. While, compared to controls, Tsc2+/- males overall exhibited higher susceptibility independently of circadian cycle, Tsc2+/- females were more susceptible during the dark and post-ovulatory phase. Interestingly, sexual dimorphisms related to KA susceptibility were always reported during light phase independently of the genetic background, with females being the most vulnerable. SIGNIFICANCE: The enhanced susceptibility in the Tsc2 mouse model suggests that other neurological alterations, beside brain lesions, may be involved in seizure occurrence for TSC. Importantly, our work highlighted the importance of considering biological sex and circadian cycle for further studies of TSC-related epilepsy research. PLAIN LANGUAGE SUMMARY: Tuberous sclerosis complex (TSC) is a rare genetic disorder. It causes brain lesions and is linked to epilepsy, intellectual disability, and autism. We wanted to investigate epilepsy in this model. We found that these mice have more induced seizures than control animals. Our results show that these mice can be used in future epilepsy research for this disorder. We also found that sex and time of day can influence the results. This must be considered in this type of research.

Rhizosphere-xylem sap connections in the olive tree microbiome: implications for biostimulation approaches.

AIMS: Climate change is endangering olive groves. Farmers are adapting by exploring new varieties of olive trees and examining the role of microbiomes in plant health.The main objectives of this work were to determine the primary factors that influence the microbiome of olive trees and to analyze the connection between the rhizosphere and endosphere compartments. METHODS AND RESULTS: The rhizosphere and xylem sap microbiomes of two olive tree varieties were characterized by next-generation 16S rRNA amplicon sequencing, and soil descriptors were analyzed. Bacterial communities in the rhizosphere of olive trees were more diverse than those found in the xylem sap. Pseudomonadota, Actinobacteriota, Acidobacteriota, and Bacillota were the dominant phyla in both compartments. At the genus level, only very few taxa were shared between soil and sap bacterial communities. CONCLUSIONS: The composition of the bacteriome was more affected by the plant compartment than by the olive cultivar or soil properties, and a direct route from the rhizosphere to the endosphere could not be confirmed. The large number of plant growth-promoting bacteria found in both compartments provides promising prospects for improving agricultural outcomes through microbiome engineering.

Efficacy and safety of induction chemotherapy in oral cavity cancer: An eight-year experience at a Portuguese reference center.

BACKGROUND: Induction chemotherapy has been described as an option in locally advanced oral cavity squamous cell carcinoma when the surgical morbidity is expected to be high. This work aimed to evaluate the outcome and safety of induction chemotherapy in this setting. METHODS: We performed a retrospective and observational study including patients with oral cavity squamous cell carcinoma, treated with induction chemotherapy between January 2010 and December 2018. Outcomes included induction chemotherapy toxicity, treatment response, disease-free survival and overall survival. RESULTS: A total of 108 oral cavity squamous cell carcinoma patients were included. Ninety-six (88.9%) had stage IV disease, while 12 (11.1%) had stage III. Eighty-four patients (80.8%) achieved at least a partial response to induction chemotherapy at clinical evaluation, and 75 (72.1%) at radiological evaluation. Seventy-eight patients have been proposed for subsequent definitive treatments, with no differences obtained in prognosis, when comparing surgical to non-surgical approaches. In patients treated with definitive treatments, improved five-year disease-free survival was obtained if at least a clinical (56.3%; p=0.001) or radiological (52.9%; p=0.001) partial response was achieved after induction chemotherapy. Similarly, superior five-year overall survival was verified for those achieving at least clinical (51.1%; p<0.0001) or radiological (52.6%; p=0.001) partial response. Also, accomplishing a pathologic complete response (n=22.6%) significantly improved disease-free survival (p=0.039) and overall survival (p=0.005). Grade 3 and 4 toxicities were observed in 52 patients (41.8%). CONCLUSION: Responses to induction chemotherapy predicted prognosis in our population, however important toxicities were observed. Further studies are necessary to identify induction chemotherapy response predictors and subgroups who may benefit from this approach.

Can a Sacrococcygeal Epidural of 0.25% Bupivacaine Prevent the Activation of the Sympathetic Nervous System during Feline Ovariectomy?

The ovariectomy (OVE) procedure can trigger somatosensory and visceral peritoneal nociception. Sacrococcygeal epidural (ScE) anesthesia may complement or replace systemic analgesia used for feline OVE, reducing opioid consumption and their related undesirable adverse effects and consequently reducing or completely blocking the sympathetic nervous system activation during this procedure. The present study aimed to evaluate the activation of the sympathetic nervous system resulting from adding an ScE injection of bupivacaine 0.25% (0.3 mL kg-1) in feline OVE and identify whether this translates to hemodynamic variables stability. A Parasympathetic Tone Activity (PTA) monitor was applied given that it performs analysis of heart rate variability (HRV) detecting changes in sympathetic and parasympathetic tone, making it a good tool for detecting activation of the sympathetic nervous system during the study. Two groups of animals were evaluated in five perioperative times, namely, the control group (CG) (n = 18) with systemic analgesia alone and the sacrococcygeal epidural group (ScEG) (n = 20) with 0.25% bupivacaine combined with systemic analgesia. Thirty-eight female cats were selected. All animals assigned to CG and ScEG were premedicated with dexmedetomidine (20 µg kg-1 IM) and methadone (0.2 mg kg-1 IM). General anesthesia was induced with propofol IV ad effectum and maintained with isoflurane in 100% oxygen. Heart rate, non-invasive systolic and median blood pressure, respiratory rate, and instantaneous parasympathetic tone activity were recorded. Compared to systemic analgesia alone (CG), sacrococcygeal epidural (ScEG) reduced the rise of common hemodynamic variables but did not prevent sympathetic nervous system activation.

Structural Design, Anticancer Evaluation, and Molecular Docking of Newly Synthesized Ni(II) Complexes with ONS-Donor Dithiocarbazate Ligands.

The current article reports the investigation of three new Ni(II) complexes with ONS-donor dithiocarbazate ligands: [Ni(L1)PPh3] (1), [Ni(L2)PPh3] (2), and [Ni(L2)Py] (3). Single-crystal X-ray analyses revealed mononuclear complexes with a distorted square planar geometry and the metal centers coordinated with a doubly deprotonated dithiocarbazate ligand and coligand pyridine or triphenylphosphine. The non-covalent interactions were investigated by the Hirshfeld surface and the results revealed that the strongest interactions were π⋅⋅⋅π stacking interactions and non-classical hydrogen bonds C-H···H and C-H···N. Physicochemical and spectroscopic methods indicate the same structures in the solid state and solution. The toxicity effects of the free ligands and Ni(II) complexes were tested on the human breast cancer cell line MCF-7 and non-malignant breast epithelial cell line MCF-10A. The half-maximal inhibitory concentration (IC50) values, indicating that the compounds were potent in inhibiting cell growth, were obtained for both cell lines at three distinct time points. While inhibitory effects were evident in both malignant and non-malignant cells, all three complexes demonstrated lower IC50 values for malignant breast cell lines than their non-malignant counterparts, suggesting a stronger impact on cancerous cell lines. Furthermore, molecular docking studies were performed showing the complex (2) as a promising candidate for further therapeutic exploration.

Repair versus replacement of defective direct dental restorations: A multinational cross-sectional study with meta-analysis.

OBJECTIVES: When dental practitioners encounter a defective restoration, they are faced with a crucial decision whether to repair or replace it. This study aims to explore international preferences for repair procedures and the clinical steps taken during the repair process. METHOD: An 11-question survey was distributed to dentists across 21 countries via different platforms. The survey comprised two sections: the first included five questions aimed at gathering demographic information, while the second consisted of six questions focusing on participants' practices related to the repair of composite or amalgam restorations A meta-analysis was employed to ascertain the pooled odds ratio of repairing versus replacement. The statistical analysis was carried out using the RevMan 5.3 program and forest plots were generated using the same program to visualize the results. RESULTS: The survey was completed by 3680 dental practitioners. The results indicated a strong tendency to repair defective composite restorations (OR: 14.23; 95 % CI: 7.40, 27.35, p < 0.001). In terms of amalgam, there was a significant tendency to replace the restorations (OR: 0.19; 95 % CI: 0.12, 0.30, p < 0.001). When repairing restorations, the most common protocols were etching with orthophosphoric acid and creating an enamel bevel, regardless of the restorative material used. CONCLUSION: The findings of this study indicate that there exists a knowledge gap among dental practitioners regarding restoration repair. It is imperative that dental practitioners receive proper education and training on restoration repair, to ensure the usage of adequate protocols and restoration survival. CLINICAL SIGNIFICANCE: A significant portion of dental practitioners lack the necessary knowledge and education required for the repair of restorations. Therefore, it is imperative to establish guidelines aimed at enhancing the management of defective restorations, along with protocols for clinical interventions. This includes the incorporation of proper courses in undergraduate, graduate, and continuing education programs.

A New Full Digital Workflow for Fixed Prosthetic Rehabilitation of Full-Arch Edentulism Using the All-on-4 Concept.

(1) Background: Recent digital workflows are being developed for full-arch rehabilitations supported by implants with immediate function. The purpose of this case series is to describe a new digital workflow for the All-on-4 concept. (2) Methods: The patients were rehabilitated using the All-on-4 concept with a digital workflow including computerized tomography scanning, intra-oral scanning, and CAD-CAM production of the temporary prosthesis, with the 3D printing of stackable guides (base guide, implant guide, and prosthetic guide). The passive fit of the prostheses and the time to perform the rehabilitations were evaluated. (3) Results: The digital workflow allowed for predictable bone reduction, the insertion of implants with immediate function, and the connection of an implant-supported prosthesis with immediate loading. The time registered to perform the full-arch rehabilitations (implant insertion, abutment connection, prosthesis connection) was below 2 hours and 30 min. No passive fit issues were noted. (4) Conclusions: within the limitation of this case series, the digital workflow applied to the All-on-4 concept using stackable base-, implant-, and prosthetic guides constitutes a potential alternative with decreased time for the procedure without prejudice of the outcome.

Compliance with the 24-h Movement Guidelines for Portuguese children: differences between boys and girls.

The 24-h Movement Guidelines for children recommend at least 60 min per day of moderate-to-vigorous intensity physical activity (PA), ≤ 2 h/day of screen time, and 9-11 h/day of sleep for children. Since little information is available on the 24-h Movement Guidelines in Portuguese children, this research attempts to know the proportion of Portuguese children meeting individual and combinations of these 24-h Movement Guidelines. Another aim of this study is to test sex differences in compliance with 24-h Movement Guidelines. A final sample of 1351 Portuguese children (51.4% girls, aged 7.65 ± 1.21) participated in this cross-sectional study. PA, screen time and sleep duration were parent-reported through a questionnaire. Only 3.7% of children met all three 24-h Movement Guidelines, whereas 11.9% met none. Although boys showed greater compliance with PA recommendations and girls with screen time recommendations, no significant sex differences were found in the compliance of all three 24-h Movement Guidelines. Given that 96.3% of Portuguese children did not meet 24-h Movement Guidelines, promoting these three movement behaviours in both boys and girls is crucial to encouraging positive consequences early.

Ongoing outbreak of hepatitis A associated with sexual transmission among men who have sex with men, Portugal, October 2023 to April 2024.

An outbreak of hepatitis A is ongoing in Portugal, with 71 confirmed cases from 7 October 2023 to 24 April 2024. Most cases are male, aged 18-44 years, with many identifying as men who have sex with men (MSM) and reported as suspected sexual transmission. Phylogenetic analysis identified the subgenotype IA, VRD 521-2016 strain, last observed in an MSM-associated multi-country outbreak in 2016 to 2018. We wish to alert colleagues in other countries to investigate potential similar spread.

Salmonella Saintpaul outbreak associated with cantaloupe consumption, the United Kingdom and Portugal, September to November 2023.

In September 2023, the UK Health Security Agency identified cases of Salmonella Saintpaul distributed across England, Scotland, and Wales, all with very low genetic diversity. Additional cases were identified in Portugal following an alert raised by the United Kingdom. Ninety-eight cases with a similar genetic sequence were identified, 93 in the United Kingdom and 5 in Portugal, of which 46% were aged under 10 years. Cases formed a phylogenetic cluster with a maximum distance of six single nucleotide polymorphisms (SNPs) and average of less than one SNP between isolates. An outbreak investigation was undertaken, including a case-control study. Among the 25 UK cases included in this study, 13 reported blood in stool and 5 were hospitalized. One hundred controls were recruited via a market research panel using frequency matching for age. Multivariable logistic regression analysis of food exposures in cases and controls identified a strong association with cantaloupe consumption (adjusted odds ratio: 14.22; 95% confidence interval: 2.83-71.43; p-value: 0.001). This outbreak, together with other recent national and international incidents, points to an increase in identifications of large outbreaks of Salmonella linked to melon consumption. We recommend detailed questioning and triangulation of information sources to delineate consumption of specific fruit varieties during Salmonella outbreaks.

Development of a predictive score to discriminate community acquired pneumonia with underlying lung cancer: A retrospective case - control study.

BACKGROUND: A pneumonic infiltrate might hide an occult lung cancer (LC). This awareness depends on each clinician personal experience, turning definitive LC diagnosis challenging and possibly delayed. In this study we aimed to develop a clinical score to better identify those cases. MATERIALS AND METHODS: We conducted a retrospective case-control study, including previously undiagnosed LC patients admitted in our institution, with a presumptive suspicious of community acquired pneumonia (CAP). Cases were compared with random CAP inpatient controls, using a matched 2:1 ratio. Demographic, clinical, and laboratorial variables were assessed for a possible association with the presence of a CAP with underlying LC (CAP-uLC). RESULTS: Among 535 hospitalized LC patients, 43 cases had a presentation compatible with CAP and were compared with 86 CAP controls. A scoring system was built using 6 independent variables, which positively correlated with CAP-uLC: smoking history (OR: 8.3 [1.9-36.2]; p = 0.005); absence of fever (6.5 [2.0-21.5]; p = 0.002); sputum with blood (5.9 [1.2-29.9]; p = 0.033); platelet count ≥ 232x103/µL (5.8 [1.6-20.6]; p = 0.006); putative alternative diagnosis than CAP (4.6 [1.5-14.7]; p = 0.009); and duration of symptoms ≥ 10 days (3.7 [1.1-13.0]; p = 0.037). Our score presented an AUC of 0.910 (95 % CI, 0.852-0.967; p < 0.001), a sensitivity of 88.1 % and specificity of 84.7 %, in predicting the risk of presenting a CAP-uLC, when set to a cutoff of 18. CONCLUSION: We propose a novel risk score aimed to aid clinicians identifying patients with CAP-uLC in the acute setting, possibly prompting early LC diagnosis.
