Clinical Phenotyping for Prognosis and Immunotherapy Guidance in Bacterial Sepsis and COVID-19.

OBJECTIVES: It is suggested that sepsis may be classified into four clinical phenotypes, using an algorithm employing 29 admission parameters. We applied a simplified phenotyping algorithm among patients with bacterial sepsis and severe COVID-19 and assessed characteristics and outcomes of the derived phenotypes. DESIGN: Retrospective analysis of data from prospective clinical studies. SETTING: Greek ICUs and Internal Medicine departments. PATIENTS AND INTERVENTIONS: We analyzed 1498 patients, 620 with bacterial sepsis and 878 with severe COVID-19. We implemented a six-parameter algorithm (creatinine, lactate, aspartate transaminase, bilirubin, C-reactive protein, and international normalized ratio) to classify patients with bacterial sepsis intro previously defined phenotypes. Patients with severe COVID-19, included in two open-label immunotherapy trials were subsequently classified. Heterogeneity of treatment effect of anakinra was assessed. The primary outcome was 28-day mortality. MEASUREMENTS AND MAIN RESULTS: The algorithm validated the presence of the four phenotypes across the cohort of bacterial sepsis and the individual studies included in this cohort. Phenotype α represented younger patients with low risk of death, ß was associated with high comorbidity burden, and δ with the highest mortality. Phenotype assignment was independently associated with outcome, even after adjustment for Charlson Comorbidity Index. Phenotype distribution and outcomes in severe COVID-19 followed a similar pattern. CONCLUSIONS: A simplified algorithm successfully identified previously derived phenotypes of bacterial sepsis, which were predictive of outcome. This classification may apply to patients with severe COVID-19 with prognostic implications.

Investigating the role of source and source trust in prebunks and debunks of misinformation in online experiments across four EU countries.

Misinformation surrounding crises poses a significant challenge for public institutions. Understanding the relative effectiveness of different types of interventions to counter misinformation, and which segments of the population are most and least receptive to them, is crucial. We conducted a preregistered online experiment involving 5228 participants from Germany, Greece, Ireland, and Poland. Participants were exposed to misinformation on climate change or COVID-19. In addition, they were pre-emptively exposed to a prebunk, warning them of commonly used misleading strategies, before encountering the misinformation, or were exposed to a debunking intervention afterwards. The source of the intervention (i.e. the European Commission) was either revealed or not. The findings show that both interventions change four variables reflecting vulnerability to misinformation in the expected direction in almost all cases, with debunks being slightly more effective than prebunks. Revealing the source of the interventions did not significantly impact their overall effectiveness. One case of undesirable effect heterogeneity was observed: debunks with revealed sources were less effective in decreasing the credibility of misinformation for people with low levels of trust in the European Union (as elicited in a post-experimental questionnaire). While our results mostly suggest that the European Commission, and possibly other public institutions, can confidently debunk and prebunk misinformation regardless of the trust level of the recipients, further evidence on this is needed.

Oral health among refugees and asylum seekers utilizing Médecins du Monde clinics in mainland Greece, 2016-2017.

BACKGROUND: The oral health of refugees and asylum seekers is understudied. However, oral health has important implications for overall health and wellbeing. This study addresses this gap by characterizing oral health care utilization in Médecins du Monde (MdM) clinics across mainland Greece from 2016 - 2017. METHODS: A retrospective cross-sectional study design was used to estimate proportional morbidities for caries, extraction, developmental, periodontal disease, preventive, and other oral health outcomes. The association between physical health conditions and consultations of interest - upper respiratory tract infections (URTIs) and reproductive health consultations - and oral health were compared using odds ratios (OR) and 95% confidence intervals (CIs). Oral health outcomes between Afghans and Syrians were compared using odds ratios and 95% CIs. RESULTS: Caries (39.44%) and extractions (28.99%) were highly prevalent in our study population. The utilization of preventive dental consultations (37.10%) was high, particularly among males. Individuals with at least one upper respiratory tract infection (OR = 1.52; 95% CI: 1.30 - 1.77; Or = 1.90; 95% CI: 1.53 - 2.36) and women and girls with reproductive health consultations (OR = 1.30; 95% CI: 1.03 - 1.66; OR = 2.03; 95% CI: 1.49 - 2.76) were more likely to have any dental or caries specific consultations. The observed patterns in oral health needs differed between Afghans and Syrians, with Afghans more likely to have preventive screenings and less likely to have caries, extractions, or other conditions. CONCLUSIONS: Displaced populations utilizing MdM dental clinics had high levels of oral health needs, particularly for caries and extractions. The connection between oral and overall health was seen in the study population, and these findings reinforce the public health importance of oral health for improving health and wellbeing of displaced populations. Evidence-informed policy, practice, and programming inclusive of oral health are needed to address both oral and overall health of refugees and asylum seekers in Greece. Future research should investigate not only oral health care needs but also knowledge and beliefs that inform utilization patterns among displaced populations.

The impact of an exercise and sport intervention on cognitive function and pain among forcibly displaced individuals at risk for PTSD: a secondary analysis of the SALEEM randomized controlled trial.

BACKGROUND: In response to the global scope of forced displacement, international organizations highlight the need of scalable solutions to support individuals' health and integration into host societies. Exposure to high mental and physical stress perceived before, during, and after displacement can impair functional capabilities, essential for adapting to a new environment. This secondary analysis examined the impact of an exercise and sport intervention on cognitive function and pain severity among individuals living in a refugee camp in Greece. METHODS: We implemented a randomized controlled trial involving n = 142 (52.8% women) forcibly displaced individuals from Southwest Asia and Sub-Saharan Africa. Participants were randomly assigned to a waitlist or a 10-week co-designed exercise and sport intervention with a 1:1 allocation rate between groups and sexes. Assessments at baseline and follow-up included the Flanker task, the Oddball paradigm, pain severity via visual analog scales, and the Åstrand-Rhyming indirect test of maximal oxygen uptake. We analyzed the intervention effects using structural equation modeling. RESULTS: Our findings did not indicate a direct intervention effect on cognitive function or pain (p ≥ .332). However, the intervention group significantly improved cardiorespiratory fitness, ß = .17, p = .010, which was associated with faster reaction times in cognitive tasks, ß = - .22, p = .004. Moreover, there was some evidence that adherence might be linked to reduced pain severity, ß = - .14, p = .065. CONCLUSIONS: Exercise and sport did not directly impact cognitive function and pain severity among a sociodemographically diverse sample living in a refugee camp, suggesting the need for complementary measures. Nevertheless, our results indicate that improvements in cardiorespiratory fitness benefit aspects of attention. TRIAL REGISTRATION: The study was approved by the local ethics committee of the University of Thessaly (no. 39) and registered prospectively on February 8, 2021 at the ISRCTN registry (no. 16291983).

Presence of asbestos in building materials and soils in postfire areas of Mati, Kineta and Varimbombi in Greece.

The present study was carried out to determine the presence of asbestos in Wildland Urban Interface (WUI) areas of Attica, Greece affected by wildfires between 2018 and 2021. It concerns the first major campaign that took place in Greece. The samples tested in this work were collected from prespecified buildings of the burned area. The samples included different types of building materials such as bricks, wall coatings, insulation plates etc. Soil samples nearby the buildings were also collected to examine dispersion of the fibers. The identification of asbestos was based on the optical properties of the fibrous particles and was performed with stereo microscope and Polarized Light Microscopy according to P401 provided by BOHS (Health and Safety Executive (HSE) 2021). Scanning Electron Microscopy with energy dispersive spectroscopy was also used to validate the presence of asbestos and determine its chemical composition. In this work, 2 different types of asbestos were determined, chrysotile and crocidolite. In some cases, fragments of asbestos containing materials were also detected in the afore-mentioned soil samples indicating dispersion of asbestos containing debris in an area around the burned spots. The presence of asbestos that was identified in this preliminary study could raise concerns to humans in the urban areas. For that reason, a risk assessment for the identified asbestos containing materials (ACMs) was conducted according to the guidelines on management and abatement of ACMs of Health and Safety Authority and the Asbestos: Survey guide, Appendix 4: Material assessment algorithm of Health and Safety Executive (HSE).

Pesticides and transformation products footprint in Greek market basket vegetables: Comprehensive screening by HRMS and health risk assessment.

Healthy dietary habits encourage vegetable consumption. Although pesticide use in crops may negatively affect human health through food intake, it can also contaminate aquatic and terrestrial environments. Thus, monitoring pesticides in high-consumption matrices is crucial. This study conducted a complete workflow of analysis, including a step of target analysis of 30 widely used pesticides and a subsequent step of suspect screening. A validated QuEChERS method was employed to analyze 61 samples of fruiting vegetables and cucurbits, packaged leafy greens, and root and tuber vegetables, commercially distributed across Greece. The method proved to be highly efficient for all validation characteristics. After target analysis, the change in the residue levels detected during sample processing was evaluated as a case study using available literature data. A health risk assessment based on diet indicated acute and chronic hazard quotients (aHQ and cHQ) and chronic hazard index (cHI) values below 1. Concerning suspect screening, 53 additional identifications of pesticides and transformation products (TPs) were revealed, totaling 86 detections. Overall, 18 parent pesticide compounds and 5 TPs were identified. Ultimately, this approach is expected to provide added value in pesticide and TPs analysis of food matrices without prior data, minimizing experimental time and costs.

Clinical Phenotyping for Prognosis and Immunotherapy Guidance in Bacterial Sepsis and COVID-19.

OBJECTIVES: It is suggested that sepsis may be classified into four clinical phenotypes, using an algorithm employing 29 admission parameters.

CONCLUSIONS: A simplified algorithm successfully identified previously derived phenotypes of bacterial sepsis, which were predictive of outcome. This classification may apply to patients with severe COVID-19 with prognostic implications.

Assessing stigma: Health and social worker regard towards working with people using illicit drugs in Athens, Greece.

BACKGROUND: After the 2008 Global Financial Crisis and resulting economic austerity, the rise in illicit drug use engendered an increased need for people who use drugs (PWUD) to access medical care, compounded by the COVID-19 pandemic. Research shows that perceptions of medical staff towards PWUD facilitate or act as a barrier to accessing health care. This study provides a better understanding of health and social work professionals' perceptions by assessing stigma levels towards PWUD in Athens, Greece. METHODS: This is a mixed-method study. It calculates the stigma score for professionals (n = 60) and the stigma score associated with specific drugs based on the Medical Condition Regard Scale through a quantitative analysis of responses to a semi-structured online survey about attitudes of health and social work professionals towards PWUD. It draws on the qualitative analysis of 12 semi-structured interviews with 16 service managers, providers, and health services advocates working in the charity sector to determine whether perceptions of PWUD affect writing and implementing policy and protocols for services. RESULTS: Stigma towards PWUD exists amongst health and social work professionals in Athens. Professionals who have worked with PWUD for longer periods of time, professionals who have had specific training on working with PWUD, and professionals who feel that they have the necessary training to work with PWUD all demonstrated a higher stigma score than those reporting the opposite. Cannabis and opioids were associated with lower stigma scores while shisha had the highest level of stigma associated with it. Finally, professional environments are not conducive to alleviating stigma as the lack of training specific to stigma, the lack of professional supervision, and worker burn-out are key barriers faced by professionals in their everyday practice. CONCLUSIONS: Reducing and eliminating stigma towards PWUD among health and social workers requires immediate action. Measures to be taken include: introducing training programs focused on stigma towards PWUD to healthcare providers, social workers, lawyers, police, the media; increasing professional supervision on field work for health and social workers; introducing low barrier health care and specialist units. Peers and field-focused organisations should meaningfully participate in drug and alcohol policymaking, program development, and implementation.

Epidemiology of Q Fever in Southeast Europe for a 20-Year Period (2002-2021).

This study aimed to assess epidemiological trends of Q fever in six countries of Southeast Europe by analysing surveillance data for 2002-2021 period. In this descriptive analysis, we collected and analysed data on confirmed human Q fever cases, obtained from the national Public Health Institutes of Bosnia and Herzegovina, Croatia, Greece, Montenegro, North Macedonia and Serbia. Overall, 2714 Q fever cases were registered during the 20-year period. The crude average annual notification rate was 0.82 (± 2.06) (95% CI: 0.47-1.16) per 100,000 inhabitants, ranged from 0.06 (± 0.04) (95% CI: 0.04-0.08) /100,000 in Greece to 2.78 (± 4.80) (95% CI: 0.53-5.02) /100,000 in the Republic of Srpska (entity of Bosnia and Herzegovina). Significant declining trends of Q fever age standardized rates were registered in Croatia, the Federation of Bosnia and Herzegovina, North Macedonia and Serbia, with an average annual change of -30.15%; -17.13%; -28.33% and - 24.77%, respectively. An unequal spatial distribution was observed. The highest average age-specific notification rate was reported in the 20-59 age group (0.84 (± 0.40) (95% CI: 0.65-1.02) /100,000). Most cases (53.69%) were reported during the spring. Q fever remains a significant public health threat in this part of Europe. The findings of this study revealed the endemic maintenance of this disease in the including countries, with large regional and subnational disparities in notification rates. A downward trend was found in Q fever notification rates across the study countries with the average notification rate higher than in the EU/EEA, during the same period.

A Study of Factors Contributing to the Nutritional Status of Elderly People Receiving Home Care.

(1) Background: Nutrition is a critical aspect of health and well-being in the elderly population, as physiological changes associated with aging can impact nutrient utilization and dietary needs. The aim of this study was the assessment of nutritional screening and associated factors among community-dwelling elderly people. (2) Methods: This study is the first phase of an intervention trial of people aged 65 years and over who received primary health services and resided in the municipality of Archanes Asterousia in Crete, Greece. Nutritional risk was assessed using the Mini Nutritional Assessment. Diet-related factors were analyzed, including health status (oral hygiene, depression, cognitive decline, impaired functioning, quality of life), social factors (educational attainment, marital status, type of work before 60 years), and lifestyle factors (smoking, drinking, diet). (3) Results: A total of 730 elderly people were evaluated (males, 31.5%), with an average age (±SD) of 76.83 (±6.68) years. MNA was found to have a statistically significant connection with assessment of oral hygiene, mental state, Charlson comorbidity, functional independence (assessed with the Barthel scale), and quality of life. The exception was geriatric depression (GDS), with which no statistically significant association was found (p > 0.05). Nutritional risk analysis revealed 379 participants (51.9%) to be adequately nourished, 205 (28.1%) to be at risk of malnutrition, and 146 (20.0%) to be malnourished. (4) Conclusions: These results clearly demonstrated the key factors that contribute to the nutritional screening of elderly people and need to be addressed by health authorities and social services.

Towards the new primary care reform in Greece: a focus on patients' expectations, views and perceptions from rural healthcare centres.

INTRODUCTION: Patient perception of quality of care is an essential component in evaluating healthcare delivery. This article reports data from primary health care (PHC) centers before Greece's most recent PHC reform. The study was undertaken to offer some baseline information about patient experience, support the decision-making processes taking place, and provide valuable input for future policy-making comparisons in Greece. METHODS: The research was conducted across the 16 PHC centers of Epirus, a region of north-western Greece, from June to September 2017, with 532 patients rating the importance of different aspects of three main healthcare domains (clinical behavior, support and services, and organization of care) of PHC provision. The Greek version of the European Task Force on Patient Evaluations of General Practice (EUROPEP) questionnaire was implemented for research purposes. Univariate comparisons were performed for patients with and without chronic disease, using Pearson's χ2 test for categorical data. RESULTS: Study findings support that the organization of care domain is of highest importance and priority, with clinical behavior and support and services following closely. Among recruited patients, on average, only 2.1% of patients with a chronic disease were satisfied (rated 4 or 5 on the Likert scale) with the organization of care aspects under consideration, compared to 18.4% of patients without a chronic disease. Furthermore, only 4% of patients with a chronic disease were satisfied with the aspects examined in the clinical behavior domain, compared to 27% of patients without a chronic disease. Finally, 18% of sampled patients with a chronic disease reported being satisfied with the quality of support and services provided, compared to 38% of patients without a chronic disease. CONCLUSION: It is necessary to back up available past information to afterwards estimate reform imprinting on expectations and perceptions. The items and aspects of EUROPEP, in line with the new tasks of the personal doctor within the PHC system that patients perceive as most essential, can be used to prioritize quality improvement activities to strengthen PHC delivery in Greece. Communication skills, practices, and behavioral change skills seem to need more attention for an efficient PHC model.

Prevalence of Neospora caninum and associated risk factors in semi-intensive female water buffaloes reared in Greece, using an ELISA kit on milk samples.

Neospora caninum is an apicomplexan (family: Sarcocystidae) protozoan parasite with a global distribution. In the N. caninum life cycle, dogs and other related canids are the definitive hosts, while other animals such as water buffaloes (Bubalus bubalis) constitute the intermediate host for this parasite. In many countries, the water buffalo is of high economic importance, providing valuable high-quality products for human needs. Although knowledge concerning the prevalence of this parasite in intermediate animal host populations is crucial, data from water buffalo are scarce. Keeping this in mind, the aim of this study was to examine the presence and assess the prevalence rates of N. caninum infection in water buffaloes in Northern Greece, where this animal husbandry sector started to raise, as well as to determine associated risk factors, with the application of a commercially available Neospora ISCOM ELISA test kit, developed for the detection of antibodies against N. caninum in milk samples The study was conducted during January-June 2023 in a total of 172 individual raw milk samples, collected from dairy buffaloes, reared under a semi extensive system, in three different farms. Information on the status of N. caninum infection in buffaloes from Greece was so far unknown with a lack of epidemiological or risk factors associated. For the detection of N. caninum, the commercially available Neospora ISCOM ELISA test kit (SANOVIR ®, Svanova Biotech AB, Uppsala, Sweden) was utilized. Results demonstrated the presence of N. caninum in water buffaloes from Greece for the first time. All positive N. caninum animal were asymptomatic, with absence of any disease signs. The overall prevalence of infection was 22.10%, whereas the main risk factors include the presence of dogs as well as the low biosecurity measures.

The use of minimum common data set in the development of the Greek Fragility Hip Fracture Registry in the Greek health care setting: the first year of its pilot implementation.

The first Fragility Hip Fracture Registry has been established in Greece. The in-hospital length of stay was 10.8 days and was significantly influenced by the delayed surgical fixation. The increased age, the higher ASA grade, and the male gender influenced negatively the 30-day mortality, which reached 7.5%. BACKGROUND: The increased incidence of fragility hip fractures constitutes a great challenge to the health care professionals and causes a significant burden on national health care systems around the globe. Fragility hip fracture registries have been used in many countries in order to document the cotemporary situation in each country and to identify potential weaknesses of the local health care systems. AIM: The aim of the herein study is to present the results of the pilot implementation of the first fragility hip fracture registry in Greece, which was developed by the Greek Chapter of Fragility Fracture Network (FFN Gr), and use the neural networks in the analysis of the results. MATERIALS AND METHODS: Seven orthopaedic departments from six different hospitals in Greece participated in the present pilot study. All fragility hip fractures from September 2022 until December 2023 were prospectively collected and documented using a central database. For this purpose, the 22 points of minimum common data set, proposed by the Global Fragility Fracture Network, with the addition of the 30-day mortality was used. RESULTS: A total of 1009 patients who sustained a fragility hip fracture were included in the study. The mean age of the cohort was 82.2 ± 8.6 years with the majority of patients being female (72%). Sixty percent (60%) of the patients had an extracapsular hip fracture, with a mean ASA grade 2.6 ± 0.8. Intramedullary nailing and hip hemiarthroplasty were the surgical treatments of choice in the majority of extra- and intra-capsular hip fractures respectively. The mean hospital length of stay of the patients was 10.8 ± 8.5 days, and the 30-day mortality was 7.5%. The multivariant analysis revealed that the age, the ASA grade and the male gender had a significant contribution to the 30-day mortality. The neural network model had a significant under-the-curve predictive value (0.778), with age being the most important predictive factor. The length of stay was significantly influenced only by the delayed surgical fixation (more than 36 h from admission). CONCLUSIONS: The present pilot study provides evidence that establishing a fragility hip fracture registry in Greece is feasible and demonstrates that the minimum common data set can be used as the base of any new registry. In Greece, patients with a fragility hip fracture stay in the hospital for approximately 11 days and have 7.5% 30-day mortality. Unfortunately, due to the logistics of the public healthcare system, they do not receive surgical fixation in a timely manner, which is a factor that negatively affects their length of in-hospital stay.

A Dietary Intervention in Adults with Overweight or Obesity Leads to Weight Loss Irrespective of Macronutrient Composition.

Obesity is a critical public health issue, necessitating effective weight loss interventions. While various dietary regimens have been explored, individual responses to interventions often vary. This study involved a 3-month dietary intervention aiming at assessing the role of macronutrient composition and the potential role of genetic predisposition in weight loss among Greek adults. This randomized clinical trial followed the CONSORT principles, recruiting 202 participants overall; 94 received a hypocaloric, high-protein diet and 108 received a high-carbohydrate, hypocaloric diet. Genetic predispositions were assessed through 10 target variants known for their BMI associations. Participants' weight and BMI values were recorded at baseline and post-intervention (n = 202 at baseline, n = 84 post-intervention) and an imputation method was applied to account for the observed missing values. Participants experienced a statistically significant weight loss across all dietary regimens (p < 0.001). Genetic analyses did not display statistically significant effects on weight loss. No significant differences in weight loss were observed between macronutrient groups, aligning with the POUNDS Lost and DIETFITS studies. This study underscores the importance of dietary interventions for weight loss and the potential contributions of genetic makeup. These findings contribute to obesity management within the Greek population and support the need for further research in personalized interventions.

Historical evolution of olive oil production processes focusing on the role of water, the contribution of energy sources, and the by-product management: The case-study of Crete, Greece.

There are numerous studies dealing with olive oil management from ancient civilizations to the mid last century, but they are limited on the historical value of information. At the same time, much knowledge is widely available and accessible on the contemporaneous production of olive oil, the necessary inputs (water and energy) and outputs (by-products) of the production process. The present study aims to shed light on olive oil extraction management from antiquity to present and to bridge the gap between archaeological and modern agricultural, engineering, and environmental disciplines. For the purposes of this study, Crete, Greece, a well-known and traditional olive oil producing region is investigated. This study is dedicated to unveil practices concerning: (a) the processing of the olives, (b) the various energy aspects per era, (c) the role of water and energy at each stage of the extraction process, and (d) management of by-products per era. The main findings support that: (a) the evolution of the extraction processes was relatively slow and remained almost the same from Minoan times until the middle of the 20th century, (b) the importance of water has been demonstrated from the beginning in the efficient extraction of the maximum amount of olive oil, (c) wastewater was first reported during the Hellenistic-Roman period due to the increased quantities produced, (d) by-product management was only considered in the previous century for environmental purposes, (e) olive oil production has been a human-based process for centuries and was greatly increased by the introduction of animals, and (f) olive oil production was further increased with the utilization of mechanical and electrical energy. It can be therefore clearly concluded that past practices have both similarities and differences with the present ones, which in turn have been optimized in terms of energy sources, water uses, olive mill equipment, and environmental considerations, to result in maximum olive oil production with minimum environmental impacts. Based on this work, important lessons can be drawn that show the historical evolution of extraction and management practices.

Implication of Apolipoprotein E gene variants in pediatric-onset multiple sclerosis: Possible association with disease susceptibility and its clinical characteristics, in a Hellenic cohort.

BACKGROUND: Apolipoprotein E (ApoE) plays a major role in lipid homeostasis and myelination in the central nervous system. Although ApoE gene variants have been linked with cognitive impairment in the setting of Multiple sclerosis (MS), no association with disease susceptibility was found, while similar studies in pediatric-onset MS (POMS) are limited. OBJECTIVE: This study aims to explore the role of ApoE gene variants in the POMS susceptibility of a Hellenic cohort and any association with disease features. METHODS: 112 POMS, fulfilling the revised IPMSSG 2013 criteria, 391 adult-onset MS (AOMS) and 200 healthy controls (HCs), were enrolled. After DNA extraction, ApoE genotyping was performed by a polymerase chain reaction and sequence-specific-oligonucleotide technique. RESULTS: ApoE2/E3 genotype and ApoE2 allele were found to be significantly more frequent among POMS patients compared to HCs [(20.5% vs 11 %, OR [95 %]: 2.1 (1.1-4.0), p = 0.03)], and [(11% vs 5.3 %, OR [95 %]: 2.3 (1.2-4.1), p = 0.01)], respectively. Additionally, significantly lower frequencies of the ApoE3/E3 genotype and the ApoE3 allele were observed in POMS patients compared to HCs (59.8% vs 79 %, OR [95 %]:0.40 (0.24-0.65), p = 0.0005 and 79% vs 89 % 0.46, OR [95 %]: (0.30-0.73), p = 0.001)], respectively. CONCLUSIONS: The ApoE2 allele may represent a novel risk factor for POMS development.

Anifrolumab for systemic lupus erythematosus with multi-refractory skin disease: A case series of 18 patients.

OBJECTIVE: Skin involvement is common in systemic lupus erythematosus (SLE), but may be resistant to conventional treatment. We sought to evaluate the efficacy of anifrolumab (ANI) in refractory cutaneous manifestations of SLE. METHODS: Case series of patients with refractory cutaneous SLE from three Rheumatology Departments in Greece. Outcome measures were improvement in Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K), physician global assessment (PGA) and Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI). Clinically relevant improvement in skin was defined as decrease ≥50% (CLASI50) from baseline values. RESULTS: Eighteen patients received ANI; all had active skin involvement at baseline. Mean (SD) SLEDAI and PGA at ANI initiation were 7.4 (2.7) and 1.4 (0.5), respectively, with a mean prednisone dose 4.9 (4.5) mg/day. Mean CLASI (Activity/Damage) at baseline was 13.9 (9.7)/2.9 (4.6). Patients were refractory to a mean 6.3 (1.5) immunomodulatory agents (including hydroxychloroquine and glucocorticoids) before the initiation of ANI. After a mean 8.5 (4.6) months, 89% (n = 16/18) of patients demonstrated significant improvement in general lupus and cutaneous disease activity, and glucocorticoid tapering. Mean SLEDAI and mean CLASI at last visit were 3.4 (1.9) and 2.1 (2.4)/1.4 (2.2), respectively, and mean daily prednisone dose decreased to 2.4 (2.2). Of note, in this group of highly refractory patients CLASI50 was achieved in 16/18 (89%) patients. One patient discontinued ANI after 4 infusions due to a varicella-zoster virus infection and one patient, who initially responded to treatment with ANI, experienced a skin flare due to temporary discontinuation due to Covid 19 infection. DORIS remission and LLDAS were attained in two (11.1%) and eleven (61.1%) patients, respectively. CONCLUSION: Anifrolumab is highly effective in various skin manifestations of SLE, even after prior failure to multiple treatments.

Unveiling the dynamics of older person care: a qualitative exploration of the intersection between formal and Informal Caregiving from the perspectives of registered nurses in Greece.

In the evolving landscape of older person care, the imperative to explore holistic approaches persists, especially in regions with distinct societal norms around informal caregiving. The deeply ingrained tradition of familial caregiving, often led by female family members, has historically compensated for healthcare system gaps in less integrated systems. Hence, societal expectations may affect registered nurses' experiences and impact the quality of care for older persons. This study aims to describe the meaning of caring for older persons in care settings in Greece. Ten in-depth interviews with registered nurses in older person care settings underwent qualitative thematic analysis. Four themes emerged from the analysis: (i) Living and bonding with older people as a basis for caring, (ii) Caring as a double-faced fulfillment, (iii) A sense of insufficiency in the caring relationship, and (iv) The encounter of existential issues creating loneliness. This research provides insights into the meaning of caring for older persons, highlighting the experiences of the closest professional caregivers of older individuals. A specific capture of the entanglement of cultural norms, societal expectations, and their impact on professional caregivers' experiences may contribute to quality care provision in systems rooted in familial caregiving traditions.

Alpine viper in changing climate: thermal ecology and prospects of a cold-adapted reptile in the warming Mediterranean.

In a rapidly changing thermal environment, reptiles are primarily dependent on in situ adaptation because of their limited ability to disperse and the restricted opportunity to shift their ranges. However, the rapid pace of climate change may surpass these adaptation capabilities or elevate energy expenditures. Therefore, understanding the variability in thermal traits at both individual and population scales is crucial, offering insights into reptiles' vulnerability to climate change. We studied the thermal ecology of the endangered Greek meadow viper (Vipera graeca), an endemic venomous snake of fragmented alpine-subalpine meadows above 1600 m of the Pindos mountain range in Greece and Albania, to assess its susceptibility to anticipated changes in the alpine thermal environment. We measured preferred body temperature in artificial thermal gradient, field body temperatures of 74 individuals in five populations encompassing the entire geographic range of the species, and collected data on the available of temperatures for thermoregulation. We found that the preferred body temperature (Tp) differed only between the northernmost and the southernmost populations and increased with female body size but did not depend on sex or the gravidity status of females. Tp increased with latitude but was unaffected by the phylogenetic position of the populations. We also found high accuracy of thermoregulation in V. graeca populations and variation in the thermal quality of habitats throughout the range. The overall effectiveness of thermoregulation was high, indicating that V. graeca successfully achieves its target temperatures and exploits the thermal landscape. Current climatic conditions limit the activity period by an estimated 1278 h per year, which is expected to increase considerably under future climate scenarios. Restricted time available for thermoregulation, foraging and reproduction will represent a serious threat to the fitness of individuals and the persistence of populations in addition to habitat loss due to mining, tourism or skiing and habitat degradation due to overgrazing in the shrinking mountaintop habitats of V. graeca.
