Background/Objectives: The miswak, crafted from the Salvadora persica tree, is a traditional teeth-cleaning twig that has served as a natural substitute for toothbrushes and toothpaste across diverse regions for centuries. This study aimed to evaluate and compare the effectiveness of miswak and a conventional toothbrush in reducing dental plaque and gingivitis over a two-week period. Methods: This two-week randomized, single-blind (clinical investigator), two-parallel-arm clinical trial was conducted at Princess Nourah University College of Dentistry (PNUCD). Stratified random sampling identified sixty participants who were then randomly assigned to two study groups: the miswak group and the toothbrushing group. To facilitate data collection, a self-designed form was employed to document participants’ initials, assigned group, the Silness and Loe plaque index, and the Loe and Silness gingival index. The clinical examination, conducted by two blinded and trained examiners using a mouth mirror and explorer under natural light, aimed to assess the specified indices. The collected data were analyzed using IBM SPSS Statistics, Version 22. Results: Following the intervention, the miswak group exhibited no significant change in the plaque scores (p = 0.58) compared to the toothbrush group (p = 0.007). A notable rise in gingival score was observed within the miswak group (p < 0.001), whereas no significant change was noted within the toothbrush group (p = 0.52). Conclusions: Over a two-week period, miswak was successful in controlling dental plaque; however, gingival scores were higher, which could be attributed to the aggressive use of miswak. With proper training, the use of miswak has the potential to contribute positively to gingival health, particularly in regions where it is readily accessible and affordable.

Published: October 2024

Background/Objectives: Mental disorders in nursing students, although very common under normal circumstances, have worsened over time due to the COVID-19 pandemic. This study aimed to assess (1) what the prevalence of anxiety and depression symptoms in Italian nursing students was and (2) what factors were associated with them. Methods: In May 2023, a cross-sectional study was conducted on the bachelor’s degree Nursing course in an Italian university. Levels of anxiety and stress were assessed using the Generalized Anxiety Disorder Scale (GAD-7) and the Patient Health Questionnaire (PHQ-9), respectively. In addition, socio-demographic variables and data on mental health, drug intake, and substance use were collected. Multiple binary logistic regression adjusted analyses were used to identify predictive factors. Results: A total of 148 nursing students completed the questionnaire. A total of 9.5% reported a previous diagnosis of a mental disorder, and, of these, 35.7% reported that it was diagnosed after the start of the COVID-19 pandemic. The mean GAD-7 and PHQ-9 score was 9.68 (SD = 5.2) and 8.37 (SD = 5.6), respectively. Protective factors for depressive symptoms included not having a previous diagnosis of a mental disorder (adjusted odds ratio = 0.10, 95% CI: 0.002–0.47, p < 0.001) and a perceived high (adjusted odds ratio = 0.03, 95% CI: 0.003–0.22 p < 0.001) or medium (adjusted odds ratio = 0.14, 95% CI: 0.03–0.82, p < 0.05) socioeconomic level, while the predictor of anxiety symptoms was returning home once a month for students studying away from their residence (adjusted odds ratio = 6.4, 95% CI: 1.01–40.8, p < 0.05). Conclusions: Urgent investments are needed in universities to implement mental health promotion programmes and to offer counselling services to reduce and prevent mental health problems among students.

Published: October 2024

Background: The Act on Life-Sustaining Treatment (LST) for patients at the end of life (the Korean LST Decision Act), implemented in the Republic of Korea in February 2018, has led to changes in the end-of-life decision-making (EOLDM) process in children. This study aimed to investigate changes in pediatric EOLDM process and LST practices since the Korean LST Decision Act. Methods: This retrospective cohort study included 107 patients who died at Kyungpook National University Children’s Hospital from January 2015 to December 2020. Patients were divided into two groups: pre-law (January 2015–January 2018, n = 55) and post-law (February 2018–December 2020, n = 52). We analyzed medical records for EOLDM process, patient characteristics, intensive care unit (ICU) admission, documentation types, and LST withholding or withdrawal decisions. Results: After the Korean LST Decision Act, the median total hospitalization duration decreased significantly (14 days [IQR, 3–80] vs. 6 days [IQR, 2–18], p = 0.020), as did the median ICU length of stay (3 days [IQR 1–33] vs. 2.5 days [IQR 1–10.3], p = 0.002). The time from admission to end-of-life decision documentation was significantly shorter in group 2 (6 days [IQR 1–31] vs. 4 days [IQR 1–9], p = 0.027). The use of physician orders for life-sustaining treatment (POLST) documents increased (0% to 33.3%), while do-not-resuscitate (DNR) orders decreased (85.3% to 16.7%). Notably, LST withdrawal decisions increased from 0% to 27.8% (p = 0.001) in the post-legislation period. Conclusions: The Korean LST Decisions Act has led to significant changes in the EOLDM process for terminally ill children, including earlier decision-making, increased use of POLST documents, more frequent LST withdrawal decisions, and shorter hospital and ICU stays. These findings suggest a shift towards more structured and timely end-of-life care discussions in pediatric settings.
AI, Cultural Heritage, and Bias: Some Key Queries That Arise from the Use of GenAI
Authors: Foka Anna , Griffin Gabriele
Published: October 2024

Our article AI, cultural heritage, and bias examines the challenges and potential solutions for using machine learning to interpret and classify human memory and cultural heritage artifacts. We argue that bias is inherent in cultural heritage collections (CHCs) and their digital versions and that AI pipelines may amplify this bias. We hypothesise that effective AI methods require vast, well-annotated datasets with structured metadata, which CHCs often lack due to diverse digitisation practices and limited interconnectivity. This paper discusses the definition of bias in CHCs and other datasets, exploring how it stems from training data and insufficient humanities expertise in generative platforms. We conclude that scholarship, guidelines, and policies on AI and CHCs should address bias as both inherent and augmented by AI technologies. We recommend implementing bias mitigation techniques throughout the process, from collection to curation, to support meaningful curation, embrace diversity, and cater to future heritage audiences.

The genetic wealth of range-restricted species is threatened by human activities such as habitat fragmentation or alteration. This research focused on the genotype effect in sexual propagation with freshly collected seeds of vulnerable local endemic plants in Crete, namely, Campanula pelviformis and Petromarula pinnata (Campanulaceae), which can be sustainably utilized for agro-alimentary, medicinal, and ornamental purposes. The morphological characteristics of seed length, width, and weight of freshly collected seeds from five wild-growing populations of C. pelviformis and seven wild-growing populations of P. pinnata from lowlands (<500 m) and semi-mountainous (>500 m) altitudes were measured and subjected to germination experiments at four incubation temperature treatments (10, 15, 20, and 25 °C). The effects of temperature, genotype, and their interactions were statistically significant for seed germination, with the results similar to those of previous studies on stored seeds of the same populations. Freshly collected seeds of both species germinated best at incubation temperatures of 10 °C and 15 °C (>68.13% for all population of C. pelviformis and >80.63% for six out of seven populations of P. pinnata), while significant differences were detected among genotypes for both species at each incubation temperature and among genotypes, even from similar altitudes. A statistically significant effect of altitude on germination percentages was observed at an incubation temperature of 20 °C between lowland and semi-mountainous genotypes for both species. The data produced in this study may enhance conservation efforts and lead to species-specific information that can be exploited in the future for their introduction as novel multi-purpose crops.

Published: October 2024

Background: Detraining refers to the decline in physical fitness that occurs after the cessation of exercise, compromising the adaptations resulting from regular exercise training. To understand how long the benefits acquired from an exercise program can be maintained, the present study evaluated the detraining effects of a 4–week exercise cessation period in older adults who performed combined training at various weekly frequencies for 12 weeks. Methods: This randomized controlled trial assigned participants to one of two training programs: a combined training program twice a week (CT2) or four times a week (CT4) over a period of 12 weeks, followed by a four–week detraining period. The resistance training consisted of six bodyweight exercises, while the aerobic training involved either walking or running. Both the CT2 and CT4 groups completed the same total training volume and overload each week; the only difference was the number of training sessions per week. Assessments were conducted at baseline, after the training period, and after the detraining period, and included the 30–s and five–repetition chair–stand tests, isometric handgrip strength, body mass index (BMI), waist circumference, and waist–to–height ratio. Results: Thirty–one participants completed the study (CT2: 17 and CT4: 14). The groups presented similar attendance records during the training period (CT2: 96 ± 18% versus CT4: 94 ± 19%). After the 12–week training period, CT2 and CT4 improved lower limb strength, CT2 improved upper limb strength, and CT4 reduced waist circumference and waist–to–height ratio compared to baseline. After the 4–week detraining period, the lower limb strength remained improved in both groups (CT2: 4 ± 1 repetition; p < 0.001 and CT4: 4 ± 1 repetition; p < 0.001) when compared to the corresponding baseline values. The handgrip strength decreased in CT2 compared to post–training values. And the body composition benefit in CT4 was not sustained after detraining. Conclusions: The effects of 4 weeks of detraining after 12 weeks of training performed two or four times per week are similar on some but not all health-related physical fitness parameters.

Objectives: This study aims to provide model-based cost–utility estimates for the addition of inspiratory muscle training (IMT) in COVID-19 pulmonary rehabilitation (PR). Methods: A cohort model comparing IMT with PR (intervention group) to IMT with only PR (control group) was used. The payer perspective from the Unified Health System in Brazil was adopted. Effectiveness parameters: Effectiveness was measured in quality-adjusted life years (QALYs). Probabilistic sensitivity analyses were performed using 1000 Monte Carlo simulations. A beta probability distribution was assumed for utilities, and a gamma distribution was applied to the costs. A cost-effectiveness threshold of BRL 40.000/QALYs was applied. Results: As the threshold of BRL 40.000/QALYs, we obtained 512 (51.2%) simulations that can be considered cost-effective to IMT added in PR programs. IMT added in PR treatment was more expensive (USD 317.73 versus USD 293.93) and more effective (incremental utility of 0.03 to INT group) than PR alone. The incremental cost-effectiveness ratio (ICER) was 793.93 USD/QALY. Conclusions: IMT added to PR is a cost-effective alternative compared with PR for post-COVID-19 patients. This strategy may result in net cost savings and improvements in the QALYs for these patients.

Published: October 2024

Pain is a chronic condition in many women; drugs used for its treatment are often accompanied by detrimental effects on many organs, including the gut. Once inflamed, the gut can affect pain processes. The aim of this study was to evaluate the general health of women suffering chronic pain, with particular attention to gastrointestinal (GI) conditions. The possibility to improve pain and quality of life through personalized nutritional advice was also tested. Forty women suffering from chronic pain were contacted for the administration of questionnaires to define their pain features and gastrointestinal conditions. Their psychological, clinical and reproductive states were also recorded. Pain scores were correlated with GI, psychological and clinical scores. Diet suggestions were given, and evaluation was repeated after 4 weeks. Thirty-eight women were included in the study: 32 suffered chronic widespread pain and had 6 pelvic pain. Pain had been present in all women for years; more than 80% of women reported various types of disorders related to the gut. Pain scores were worse in the women intolerant to milk and dairy products. The GI score was positively correlated with the pain score. The Dietary Inflammatory Index was very high in all subjects. Personalized nutritional advice followed by 26 subjects for 4 weeks resulted in a significant improvement of pain and quality of life parameters. We describe women with chronic pain as being particularly affected by GI alterations. The change in feeding habits had a beneficial effect on pain and other quality of life parameters.

Published: October 2024

Citrus canker, a highly transmissible bacterial disease, has three major types, with Asiatic canker (Canker A), caused by Xanthomonas citri pv. citri (Xcc A), being the most widespread and severe, affecting most citrus varieties. Xcc A has two mild variants, Xcc A* and Aw with a limited host range, reported in Southwest Asia and Florida, respectively. Since 2015, the canker caused by Xcc Aw has been being reported in the Rio Grande Valley of South Texas where the Texas commercial citrus industry is located. In 2016, a more severe Canker A was reported in the upper Texas gulf coast region, north of the Rio Grande Valley, posing a potential threat to the Texas citrus industry. Given that existing diagnostic methods cannot reliably distinguish Xcc Aw from Xcc A, we developed a loop-mediated isothermal amplification (LAMP) assay specific to Xcc Aw (LAMP-Aw) for rapid, field-based identification of this bacterial variant. The detection limit of LAMP-Aw was ~4.52 Log10 copies of the target molecule. This study also evaluated the field applicability of the LAMP-Aw assay by coupling the LAMP-Aw assay with a lateral flow immunoassay system.

Published: October 2024

Lipase, a type of enzyme that decomposes and synthesizes triglycerides, plays an important role in lipid processing. In this study, a heat-resisting lipase gene (lip4) from Thermomyces lanuginosus was subcloned into the pPICZαA vector and then transformed into Pichia pastoris X33. The recombinant yeast cell concentration reached the maximum (119.5 g/L) at 144 h, and the lipase (Lip4) activity reached the maximum (3900 U/mL) at 168 h in 10 L bioreactor. Through bioinformatics analysis, S168, as the key site of Lip4, participated in the formation of the catalytic triads S168-D223-H280 and G166-H167-S168-L169-G170. Furthermore, S168 and seven conserved amino acids of G104/288, S105, A195, P196, V225 and I287 constitute the active center of Lip4. Specifically, the structure modeling showed two α-helices of the lid domain, outside the active pocket domain, controlling the entry of the substrate on Lip4. The potential glycosylation of Asn-33 may be involved in exhibiting the high stable temperature for lipase activity. Therefore, the eukaryotic system was constructed to express Lip4 efficiently, and the amino acid sites related to the catalytic efficiency of Lip4 were clarified, providing a new way for its subsequent property research and industrial application.

Published: October 2024

Given the rapid advancement of functional 1,8-Naphthalimide derivatives in anticancer research, we synthesized these two novel naphthalimide derivatives with diverse substituents and investigated the effect on glioblastoma multiforme (GBM) cells. Cytotoxicity, apoptosis, cell cycle, topoisomerase II and Western blotting assays were evaluated for these compounds against GBM in vitro. A human GBM xenograft mouse model established by subcutaneously injecting U87-MG cells and the treatment responses were assessed. Both compounds 3 and 4 exhibited significant antiproliferative activities, inducing apoptosis and cell death. Only compound 3 notably induced G2/M phase cell cycle arrest in the U87-MG GBM cells. Both compounds inhibited DNA topoisomerase II activity, resulting in DNA damage. The in vivo antiproliferative potential of compound 3 was further validated in a U87-MG GBM xenograft mouse model, without any discernible loss of body weight or kidney toxicity noted. This study presents novel findings demonstrating that 1,8-Naphthalimide derivatives exhibited significant GBM cell suppression in vitro and in vivo without causing adverse effects on body weight or kidney function. Further experiments, including investigations into mechanisms and pathways, as well as preclinical studies on the pharmacokinetics and pharmacodynamics, may be instrumental to the development of a new anti-GBM compound.
Epigenetic DNA Methylation and Protein Homocysteinylation: Key Players in Hypertensive Renovascular Damage
Authors: Ren Lu , Pushpakumar Sathnur , Almarshood Hebah , Das Swapan K. , Sen Utpal
Published: October 2024

Hypertension has been a threat to the health of people, the mechanism of which, however, remains poorly understood. It is clinically related to loss of nephron function, glomerular sclerosis, or necrosis, resulting in renal functional declines. The mechanisms underlying hypertension’s development and progression to organ damage, including hypertensive renal damage, remain to be fully elucidated. As a developing approach, epigenetics has been postulated to elucidate the phenomena that otherwise cannot be explained by genetic studies. The main epigenetic hallmarks, such as DNA methylation, histone acetylation, deacetylation, noncoding RNAs, and protein N-homocysteinylation have been linked with hypertension. In addition to contributing to endothelial dysfunction and oxidative stress, biologically active gases, including NO, CO, and H2S, are crucial regulators contributing to vascular remodeling since their complex interplay conducts homeostatic functions in the renovascular system. Importantly, epigenetic modifications also directly contribute to the pathogenesis of kidney damage via protein N-homocysteinylation. Hence, epigenetic modulation to intervene in renovascular damage is a potential therapeutic approach to treat renal disease and dysfunction. This review illustrates some of the epigenetic hallmarks and their mediators, which have the ability to diminish the injury triggered by hypertension and renal disease. In the end, we provide potential therapeutic possibilities to treat renovascular diseases in hypertension.

Published: October 2024

Pulmonary hypertension (PH) significantly impairs exercise capacity and the quality of life in patients, which is influenced by dysfunctions in multiple organ systems, including the right ventricle, lungs, and skeletal muscles. Recent research has identified metabolic reprogramming and mitochondrial dysfunction as contributing factors to reduced exercise tolerance in PH patients. In this study, we investigated the therapeutic potential of enhancing mitochondrial function through the activation of the mitochondrial deacetylase SIRT3, using SIRT3 activator Honokiol combined with the SIRT3 co-factor nicotinamide adenine dinucleotide (NAD), in a Sugen/Hypoxia-induced PH rat model. Our results show that Sugen/Hypoxia-induced PH significantly impairs RV, lung, and skeletal muscle function, leading to reduced exercise capacity. Treatment with Honokiol and NAD notably improved exercise endurance, primarily by restoring SIRT3 levels in skeletal muscles, reducing proteolysis and atrophy in the gastrocnemius, and enhancing mitochondrial complex I levels in the soleus. These effects were independent of changes in cardiopulmonary hemodynamics. We concluded that targeting skeletal muscle dysfunction may be a promising approach to improving exercise capacity and overall quality of life in PH patients.
Water Extract of Pulsatilla koreana Nakai Inhibits Osteoclast Differentiation and Alleviates Ovariectomy-Induced Bone Loss

Published: October 2024

Pulsatilla koreana Nakai (P. koreana) is a perennial herb traditionally used to treat malaria and fever. Although the pharmacological properties of P. koreana have been explored in various contexts, its effects on bone diseases, such as osteoporosis, remain poorly studied. In this study, we investigated the effects of water extracts of P. koreana (WEPK) on osteoclasts, which play a crucial role in bone remodeling, and an ovariectomized (OVX) mouse model, which mimics osteoporosis. Phytochemical profiling of WEPK revealed several compounds that regulate bone or fat metabolism. WEPK suppressed osteoclast differentiation by downregulating the expression of receptor activator of nuclear factor-κB ligand (RANKL), a cytokine that induces osteoclastogenesis. Additionally, WEPK directly inhibited RANKL-induced differentiation of osteoclast precursors by downregulating nuclear factor of activated T cells 1 (NFATc1), the master transcription factor for osteoclastogenesis, by modulating its upstream regulators. In vivo, oral administration of WEPK suppressed bone loss, reduced weight gain, and mitigated fat accumulation in the liver and gonadal tissues of OVX mice. Given its positive impact on bone and fat accumulation under estrogen deficiency, WEPK may serve as a promising alternative therapy for postmenopausal osteoporosis, especially when accompanied by other metabolic disorders, such as obesity and fatty liver.

Published: October 2024

The skin is covered by a protective mucus layer, which is essential to the innate defense mechanism of fish. Investigating the response of skin mucus to various toxic stresses is crucial for enhancing its ability to tackle environmental challenges and developing strategies to mitigate toxic effects. Alkalinity stress assays (50 mmol/L NaHCO3) were conducted on crucian carp (Carassius auratus) from Lake Dali Nur (pH = 9.6) and Ping Xiang red crucian carp from freshwater (pH = 7) over 7 days. The expression of skin mucous proteins was analyzed using the liquid chromatography (LC)-spectrometry (MS)/MS Analysis-Data-independent acquisition (DIA) mode. A total of 12,537 proteins were identified across 20 samples from four groups, with 12,025 quantified. In the alkaline water population, high alkali stress resulted in the up-regulation of 139 proteins and the down-regulation of 500 proteins. In contrast, the freshwater population showed an increase in 112 proteins and a decrease in 120; both populations had a total of 23 genes up-regulated and 21 down-regulated. The protein regulatory network for the alkaline water group included 3146 pairwise interactions among 464 nodes, with only 20 being differentially expressed proteins. Conversely, the freshwater group’s network comprised just 1027 specific interactions across 337 nodes, with 6 corresponding to differentially expressed proteins. A common protein regulatory network responding to high alkali stress was extracted and visualized for both populations. Based on their regulatory relationships and expression levels, these proteins are hypothesized to play similar roles under high alkali stress. Notably, the alpha-globin fragment and keratin type I cytoskeletal 13-like proteins showed markedly up-regulated expression, with the alpha-globin fragment increasing nearly a thousandfold from an extremely low level. This suggests it could serve as a potential biomarker for alkali tolerance, warranting further investigation.
Exploring the Role of Endophytes in Cannabis sativa L. Polyploidy and Agricultural Trait Improvement
Authors: Srivastava Ankita , Sharbel Timothy , Vujanovic Vladimir
Published: October 2024

Here, we examine the effects of ploidy variation in Cannabis sativa L. cell lines on the plant host genotype-associated microbiome. The endophytic microbiome has a protocooperative role in improving plant health and productivity and represents an alternative to synthetic chemical fertilizers and pesticides in sustainable agriculture. This study assessed the effects of seed endophytes on diploid and triploid Haze hemp cultivars. Key phenotypic characteristics were evaluated, revealing significant differences in seed germination in vitro as well as vegetative growth and flowering in phytotron conditions. Endophyte-treated triploid plants exhibited significantly taller heights compared to diploids (p < 0.01). These treated triploid plants also showed longer leaves at nodes 2, 6, and 8, except at node 4, indicating a plant in transition from vegetative growth to the generative developmental stage. Additionally, triploids treated with endophytes displayed the highest number of axillary branches, while endophyte-treated diploids had the fewest (p < 0.05). Both cultivars treated with endophytes exhibited a higher number of inflorescences compared to untreated control plants. This study revealed for the first time a direct correlation between the shifts in diameter of the stem and the biomass in both tested hemp hosts, in association with endophytic microbiomes.
Increasing the Oxygen Consumption in Hermetic Grain Storage Using Grain Weevils (Sitophilus granarius)
Authors: Müller-Blenkle Christina , Adler Cornel S.
Published: October 2024

Loss of stored plant products due to insect infestation is a problem that is likely to increase with global warming. Improved storage under hermetic conditions in oxygen deficiency can prevent or control infestation and preserve product quality. Oxygen levels in hermetic storage decrease due to different factors, one of which is the oxygen consumption of the insects present. Experiments were carried out using varying numbers (25, 50, or 200) of all developmental stages of the grain weevil Sitophilus granarius L. (eggs, larvae, pupae, and adult beetles) caged and placed in sealed 30-L containers containing 22 kg of wheat for at least 21 weeks. Oxygen levels were measured at regular intervals. The oxygen consumption depended on the number of insects and went below the critical threshold of 3% for S. granarius survival in most of the trials. Some surviving beetles were observed at the end of the hermetic experiments and 12 weeks afterwards during control for progeny, when oxygen levels did not fall below the critical threshold or the low level could not be maintained for a sufficient time. Monitoring oxygen levels in hermetic storage is therefore essential to ensure safe storage over long periods.

Authors: Sellali Sabrina , Lafri Ismail , Garni Rafik , Manseur Hemza , Besbaci Mohamed , Lafri Mohamed , Bitam Idir
Published: October 2024

Eight sandfly-borne phleboviruses were found to circulate in North Africa. Phleboviruses detected in sandflies were Toscana (TOSV), Sandfly Fever Sicilian (SFSV), Sandfly Fever Naples (SFNV), Cyprus (CYPV), Punique (PUNV), Utique, Saddaguia, and Medjerda Valley (MVV) viruses, yielding an overall infection rate of 0.02–0.6%. Phlebotomus perniciosus and Phlebotomus longicuspis were the most common vector species in the region. TOSV seroprevalence in dogs from Algeria (4.56%) and Tunisia (7.5%) was low and close, unlike SFSV (38.1%) and PUNV (43.5%), which were restricted to Tunisia. SFSV (1.3–21%) and TOSV (3.8–50%) were the most prevalent among humans. TOSV was frequently detected and symptomatically confirmed in both Algeria (3.8%) and Tunisia (12.86%). Other sandfly-borne phleboviruses have also been detected but less importantly, such as SFNV in Morocco (2.9%) and Tunisia (1.1%) and PUNV (8.72%), CYPV (2.9%), and MVV (1.35%) in Tunisia. Their distribution was mainly northern. Overall, 15.9% of the healthy population were seropositive for sandfly-borne phleboviruses, with evidenced cocirculation. Noticeably, studies conducted in Morocco were mostly interested in TOSV in sandflies. Available data from Libya and Egypt were scant or historical. Further elaboration is required to check the sporadic detection of less-prevalent phleboviruses and fully elucidate the epidemiological situation.

Published: October 2024

Objectives: To assess whether continuous non-invasive pCO2 monitoring by transcutaneous pCO2 monitor (TCpCO2) among extremely low birth weight (ELBW) premature infants, during the first week of life, will decrease the rate of high-grade intraventricular hemorrhage (IVH) or periventricular leukomalacia (PVL) or the combined outcome of IVH/PVL and death. Methods: This was a prospective, observational, multicenter study. Due to ethical constraints, allocation was based on TCpCO2 monitor availability. ELBW infants were either monitored by TCpCO2 monitor (Sentec, Therwil, Switzerland) (study group), or recruited to the control group if a TCpCO2 monitor was not available. Results: A total of 132 ELBW infants participated in the study. The size of the study group (106 infants) and the control group (26 infants) differed because monitor availability increased during the study period reflecting change in standard of care. The groups had comparable gestational age and baseline characteristics. No difference was found in the rate of IVH/PVL in the study vs. control groups (10% vs. 4%; p = 0.7, respectively), or in the combined outcome of PVL/IVH and death (16% vs. 15%; p = 1.0, respectively). Conclusions: This study demonstrates the challenges in conducting a prospective controlled trial in a rapidly evolving medical field. While the study began with a clear equipoise, this balance shifted as the care team gained more experience with TCpCO2 monitoring among the study population, despite the absence of new clinical evidence to justify such a shift. Consequently, the small control group limited our ability to draw definitive conclusions regarding the study’s objective. However, our findings may increase awareness of continuous non-invasive pCO2 monitoring in extremely premature infants.

Background/Objectives: The increasing global prevalence of inflammatory bowel disease (IBD) presents significant challenges to healthcare systems. Our objective was to identify the sociodemographic and clinical characteristics of IBD patients in Catalonia. Methods: A cross-sectional analytical study was carried out on patients diagnosed with IBD in Catalonia (2021). The database of the Information System for the Development of Research in Primary Care of Catalonia was used. Results: In Catalonia, the prevalence of IBD was 474 cases per 100,000 people (pcm), with an average diagnosis age of 42.9 years. Crohn’s disease (CD) represented 34.34% of cases, and 21.2% were smokers and 1% were alcoholics. Nutritional status showed 3% underweight, 36.2% overweight, and 20% obese, with only 0.27% diagnosed as malnutrition. Mental health issues are notable; 36,531 pcm patients were diagnosed with anxiety and 14,656 pcm with depression, and 8.24% had a high risk of mortality measured by the Charlson index. The most prevalent vaccine-preventable infections were influenza (19,356 pcm), herpes zoster (8099 pcm), and varicella zoster (6946 pcm), with 4.56% of patients requiring hospitalisation for one of these reasons and 32.8% of patients for IBD complications, with higher rates observed in cases of CD. Conclusions: The prevalence of IBD was high, especially in urban areas, and patients showed a relevant number of comorbidities. IBD requires a comprehensive evaluation and interdisciplinary management to improve disease control.

Background: The aim of this study was to assess the diagnostic performance of contrast-enhanced ultrasound (CEUS) in characterizing small renal masses (SRMs) measuring less than 3 cm and in distinguishing between malignant and benign SRMs. Methods: A retrospective study was conducted between January 2022 and January 2023 at the Radiology Department of (Anonymized data), with a total of 43 patients assessed via CT and MRI scans, which were subsequently studied by experienced radiologists who were blinded to the pathology results. The CEUS findings were then compared with histopathological examination outcomes or follow-up imaging results. Results: The study results revealed a notably high level of diagnostic accuracy, with sensitivity at 0.875, specificity at 0.94, positive predictive value at 0.95, and negative predictive value at 0.86 for characterizing SRMs. Spearman rank correlation analysis substantiated a robust positive linear correlation between the CEUS findings and biopsy results (r = 0.972). Conclusions: These findings underscore the potential utility of CEUS as a valuable tool for discriminating between malignant and benign SRMs, carrying significant implications for clinical decision-making and leading to improved patient outcomes. However, larger validation studies are imperative to establish its role in routine clinical practice and to address potential limitations.

Background: Nearly half of congenital heart defects (CHDs) related to mortality occur during infancy although advancements in treatments have increased the survival rates. This study comprehensively examined overall and surgical mortality in CHD infants with the highest mortality rates in an effort to improve our understanding of CHD epidemiology. Methods: Participants were drawn from a dataset of 1,964,691 infants born between 2014 and 2018 in Korea. Crucial CHDs are defined here as including diverse categorical defects and classical critical CHDs but excluding simple shunt defects. Overall mortality (procedural and natural mortality) and procedural mortality (interventional and surgical mortality) for infants were analyzed. Results: The performance rate for multiple procedures in infants with crucial CHDs was 16%. The overall and surgical mortalities of crucial CHDs were 8% and 7%. The mortalities of palliative procedures were relatively high. Procedural mortalities for infants were significantly decreased in the tetralogy of Fallot (TOF), atrioventricular septal defects, and total anomalous pulmonary venous return (TAPVR) compared with overall mortalities for infants. Surgical mortalities for infants involving TOF and TAPVR were significantly lower, but those for infants involving hypoplastic left heart syndrome (HLHS) were higher than those for all ages. Conclusions: Palliative procedural techniques in infants must be improved to obtain better outcomes, particularly in the palliative surgery of HLHS. The infantile procedural outcomes for TOF and TAPVR are excellent and important in order to overcome disastrous circumstances during infancy. This comprehensive study of the overall and procedural mortalities of CHDs may have laid a cornerstone for CHD epidemiology in Korean infants.
The Influence of Dopaminergic Medication on Regularity and Determinism of Gait and Balance in Parkinson’s Disease: A Pilot Analysis

Published: October 2024

Background/Objectives: Understanding how dual-tasking and Parkinson’s disease medication affect gait and balance regularity can provide valuable insights to patients, caregivers, and clinicians regarding frailty and fall risk. However, dual-task gait and balance studies in PD most often only employ linear measures to describe movement regularity. Some have used nonlinear techniques to analyze PD performances, but only in the on-medication state. Thus, it is unclear how the nonlinear aspects of gait or standing balance are affected by PD medication. This study aimed to assess how dopaminergic medication influenced the regularity and determinism of joint angle and anterior–posterior (AP) and medial–lateral (ML) center of pressure (COP) path time-series data while single- and dual-tasking in PD. Methods: Sixteen subjects with PD completed single- and dual-task gait and standing balance trials for 3 min off and on dopaminergic medication. Sample entropy and percent determinism were calculated for bilateral hip, knee, and shoulder joints, and the AP and ML COP path. Results: There were no relevant medication X task interactions for either the joint angles series or the balance series. Instead, the results supported independent effects of medication, dual-tasking, or standing with eyes closed. Balance task difficulty (i.e., eyes open vs. eyes closed) was detected by the nonlinear analyses, but the nonlinear measures yielded opposing results such that standing with eyes closed simultaneously yielded less regular and more deterministic signals. Conclusions: When juxtaposed with previous findings, these results suggest that medication-induced functional improvements in people with PD might be accompanied by a shift from lesser to greater signal consistency, and the effects of dual-tasking and standing with eyes closed were mixed. Future studies would benefit from including both linear and nonlinear measures to better describe gait and balance performance and signal complexity in people with PD.

Background: Traumatic injury is a leading cause of death and disability in children and young adults. There is a lack of evidence-based literature and guidelines on supporting families after severe child injury. This study aimed to assess the family needs and factors associated with those needs. Methods: A prospective multicenter follow-up study conducted at two Norwegian trauma centers involving children (aged 0–18 years) who sustained a moderate or severe traumatic injury with a New Injury Severity Score > 9. Sociodemographic and injury variables were recorded at baseline. The Family Needs Questionnaire—Paediatric Version, ranging from one (not at all met) to five (completely met) was completed by parents to assess the family needs at the 6-month follow-up. Bivariate logistic regression analyses were conducted to identify the factors associated with the family needs at 6 months post-injury. Results: Of the 63 children included, 38 (68% boys) with a mean age of 9.9 years (SD = 5.8) were available for follow-up. At 6 months, 82% reported needs for health information with a mean score of 3.8 (SD = 1.0), and involvement with care with a mean of 3.7 (SD = 1.2). Additionally, 71% reported emotional support needs (mean score 2.6, SD = 1.3). A higher number of injuries and a lower age of the child were significantly associated with increased odds of having more family needs. Conclusions: After moderate to severe pediatric traumatic injury, families report a need for health information, involvement in care, and emotional support. Paying attention to the number of injuries and the child’s age could help to identify families in need of information and support.

Published: October 2024

Background/Objectives: Polymyalgia Rheumatica (PMR) is an inflammatory condition that primarily affects individuals aged 50 and older, especially in Western countries. Although glucocorticoids are the cornerstone of PMR treatment, these drugs are associated with side effects, making it advisable to use them for the shortest duration possible. However, tapering or discontinuation of glucocorticoids often leads to disease relapses. In this review, we focus on the traditional management of PMR, as well as the potential for therapies that may reduce glucocorticoid use. Special attention is given to the efficacy of biologic agents in PMR management. Methods: A literature review, primarily based on articles published in PubMed, was conducted. In addition to discussing various glucocorticoids and conventional disease-modifying drugs used for the management of isolated PMR, this review specifically focused on the information reported regarding new therapies, with particular emphasis on biologic agents. Results: Prednisone or prednisolone at a dose ranging between 12.5 and 25 mg/day is the agreed-upon treatment for PMR. Due to the side effects associated with prolonged glucocorticoid use and the high frequency of relapses when glucocorticoids are tapered, glucocorticoid-sparing agents have emerged as tools in the management of PMR. Methotrexate has traditionally been the conventional disease-modifying antirheumatic drug (DMARD) unanimously recommended for use in PMR. Other conventional DMARDs, such as leflunomide, have shown promising results but require further study. The use of biologic agents has marked a significant step forward in the management of PMR. While anti-TNF agents failed to provide beneficial effects in isolated PMR, anti-IL-6 receptor agents, such as tocilizumab and sarilumab, have demonstrated efficacy in reducing relapse frequency, lowering the cumulative glucocorticoid burden, and achieving long-term remission of the disease. Other biologic agents, many of which have been used in giant cell arteritis, as well as Janus kinase (JAK) inhibitors, are currently under investigation. Conclusions: Glucocorticoids are the primary treatment for isolated PMR but are associated with comorbidities, especially in patients with pre-existing conditions or frequent relapses. Glucocorticoid-sparing agents, such as methotrexate and biologics, in particular tocilizumab and sarilumab, offer alternatives, improving symptoms and reducing glucocorticoid use. While biologic agents reduce long-term side effects and help achieve disease remission, their use must consider potential side effects and higher costs compared to traditional therapies.
