RESUMO

BACKGROUND: A sizeable proportion of pathogenic genetic variants identified in young children tested for congenital differences are associated with neurodevelopmental psychiatric disorders (NPD). In this growing group, a genetic diagnosis often precedes the emergence of diagnosable developmental concerns. Here, we describe DAGSY (Developmental Assessment of Genetically Susceptible Youth), a novel interdisciplinary 'genetic-diagnosis-first' clinic integrating psychiatric, psychological and genetic expertise, and report our first observations and feedback from families and referring clinicians. METHODS: We retrieved data on referral sources and indications, genetic and NPD diagnoses and recommendations for children seen at DAGSY between 2018 and 2022. Through a survey, we obtained feedback from twenty families and eleven referring clinicians. RESULTS: 159 children (mean age 10.2 years, 57.2% males) completed an interdisciplinary (psychiatry, psychology, genetic counselling) DAGSY assessment during this period. Of these, 69.8% had a pathogenic microdeletion or microduplication, 21.5% a sequence-level variant, 4.4% a chromosomal disorder, and 4.4% a variant of unknown significance with emerging evidence of pathogenicity. One in four children did not have a prior NPD diagnosis, and referral to DAGSY was motivated by their genetic vulnerability alone. Following assessment, 76.7% received at least one new NPD diagnosis, most frequently intellectual disability (24.5%), anxiety (20.7%), autism spectrum (18.9%) and specific learning (16.4%) disorder. Both families and clinicians responding to our survey expressed satisfaction, but also highlighted some areas for potential improvement. CONCLUSIONS: DAGSY addresses an unmet clinical need for children identified with genetic variants that confer increased vulnerability for NPD and provides a crucial platform for research in this area. DAGSY can serve as a model for interdisciplinary clinics integrating child psychiatry, psychology and genetics, addressing both clinical and research needs for this emerging population.

RESUMO

Objective: The COVID-19 pandemic was associated with a reduction in the incidence of myocardial infarction (MI) diagnosis, in part because patients were less likely to present to hospital. Whether changes in clinical decision making with respect to the investigation and management of patients with suspected MI also contributed to this phenomenon is unknown. Methods: Multicentre retrospective cohort study in three UK centres contributing data to the National Institute for Health Research Health Informatics Collaborative. Patients presenting to the Emergency Department (ED) of these centres between 1st January 2020 and 1st September 2020 were included. Three time epochs within this period were defined based on the course of the first wave of the COVID-19 pandemic: pre-pandemic (epoch 1), lockdown (epoch 2), post-lockdown (epoch 3). Results: During the study period, 10,670 unique patients attended the ED with chest pain or dyspnoea, of whom 6,928 were admitted. Despite fewer total ED attendances in epoch 2, patient presentations with dyspnoea were increased (p < 0.001), with greater likelihood of troponin testing in both chest pain (p = 0.001) and dyspnoea (p < 0.001). There was a dramatic reduction in elective and emergency cardiac procedures (both p < 0.001), and greater overall mortality of patients (p < 0.001), compared to the pre-pandemic period. Positive COVID-19 and/or troponin test results were associated with increased mortality (p < 0.001), though the temporal risk profile differed. Conclusions: The first wave of the COVID-19 pandemic was associated with significant changes not just in presentation, but also the investigation, management, and outcomes of patients presenting with suspected myocardial injury or MI.

RESUMO

The personalised oncology paradigm remains challenging to deliver despite technological advances in genomics-based identification of actionable variants combined with the increasing focus of drug development on these specific targets. To ensure we continue to build concerted momentum to improve outcomes across all cancer types, financial, technological and operational barriers need to be addressed. For example, complete integration and certification of the 'molecular tumour board' into 'standard of care' ensures a unified clinical decision pathway that both counteracts fragmentation and is the cornerstone of evidence-based delivery inside and outside of a research setting. Generally, integrated delivery has been restricted to specific (common) cancer types either within major cancer centres or small regional networks. Here, we focus on solutions in real-world integration of genomics, pathology, surgery, oncological treatments, data from clinical source systems and analysis of whole-body imaging as digital data that can facilitate cost-effectiveness analysis, clinical trial recruitment, and outcome assessment. This urgent imperative for cancer also extends across the early diagnosis and adjuvant treatment interventions, individualised cancer vaccines, immune cell therapies, personalised synthetic lethal therapeutics and cancer screening and prevention. Oncology care systems worldwide require proactive step-changes in solutions that include inter-operative digital working that can solve patient centred challenges to ensure inclusive, quality, sustainable, fair and cost-effective adoption and efficient delivery. Here we highlight workforce, technical, clinical, regulatory and economic challenges that prevent the implementation of precision oncology at scale, and offer a systematic roadmap of integrated solutions for standard of care based on minimal essential digital tools. These include unified decision support tools, quality control, data flows within an ethical and legal data framework, training and certification, monitoring and feedback. Bridging the technical, operational, regulatory and economic gaps demands the joint actions from public and industry stakeholders across national and global boundaries.

RESUMO

Achieving colloidal and chemical stability in ferrofluids by surface modification requires multiple steps, including purification, ex situ modification steps, and operation at high temperatures. In this study, a single-step microwave-assisted methodology is developed for iron oxide nanoparticle (IONP) synthesis utilizing a series of imidazolium-based ionic liquids (ILs) with chloride, bis(trifluoromethylsulfonyl)imide, and pyrrolide anions as the reaction media, thus eliminating the use of volatile organics while enabling rapid synthesis at 80 °C as well as in situ surface functionalization. The characterized surface functionality, hydrodynamic particle size, magnetization, and colloidal stability of the IONPs demonstrate a strong dependence on the IL structure, ion coordination strength, reactivity, and hydrophilicity. The IONPs present primarily a magnetite (Fe3O4) phase with superparamagnetism with the highest saturation magnetization at 81 and 73 emu/g at 10 and 300 K, respectively. Depending on the IL coating, magnetization and exchange anisotropy decrease by 20 and 2-3 emu/g (at 35 wt % IL), respectively, but still represent the highest magnetization achieved for coated IONPs by a coprecipitation method. Further, the surface-functionalized superparamagnetic magnetite nanoparticles show good dispersibility and colloidal stability in water and dimethyl sulfoxide at 0.1 mg/mL concentration over the examined 3 month period. This study reports on the intermolecular and chemical interactions between the particle surface and the ILs under synthetic conditions as they relate to the magnetic and thermal properties of the resulting IONPs that are well suited for a variety of applications, including separation and catalysis.

RESUMO

Single-site copper-based catalysts have shown remarkable activity and selectivity for a variety of reactions. However, deactivation by sintering in high-temperature reducing environments remains a challenge and often limits their use due to irreversible structural changes to the catalyst. Here, we report zeolite-based copper catalysts in which copper oxide agglomerates formed after reaction can be repeatedly redispersed back to single sites using an oxidative treatment in air at 550 °C. Under different environments, single-site copper in Cu-Zn-Y/deAlBeta undergoes dynamic changes in structure and oxidation state that can be tuned to promote the formation of key active sites while minimizing deactivation through Cu sintering. For example, single-site Cu2+ reduces to Cu1+ after catalyst pretreatment (270 °C, 101 kPa H2) and further to Cu0 nanoparticles under reaction conditions (270-350 °C, 7 kPa EtOH, 94 kPa H2) or accelerated aging (400-450 °C, 101 kPa H2). After regeneration at 550 °C in air, agglomerated CuO was dispersed back to single sites in the presence and absence of Zn and Y, which was verified by imaging, in situ spectroscopy, and catalytic rate measurements. Ab initio molecular dynamics simulations show that solvation of CuO monomers by water facilitates their transport through the zeolite pore, and condensation of the CuO monomer with a fully protonated silanol nest entraps copper and reforms the single-site structure. The capability of silanol nests to trap and stabilize copper single sites under oxidizing conditions could extend the use of single-site copper catalysts to a wider variety of reactions and allows for a simple regeneration strategy for copper single-site catalysts.

RESUMO

QF-PCR is a widely used molecular biology method. To name just a few of its uses, it is considered to be useful in paternity tests, identification tests or prenatal diagnostics. Therefore, there is a good chance that medical faculty students would come into contact with this technology - directly or indirectly - during their professional work. The following article proposes a teaching classes scenario conducted in the problem-based learning manner, which aims to familiarize students with the QF-PCR technique. In addition, other modern methods of molecular genetics are among topics that students can learn during the problem-based learning modules. The classes are divided into three parts. In the first part, students learn about the possible usage of QF-PCR in paternity tests. The second part focuses on learning about the advantages and limitations of QF-PCR in prenatal diagnosis. Learning activities in the last part are designed to show the limitations of the diagnostic properties of the method - students analyze the case study, in which QF-PCR must be replaced by other modern methods of molecular genetics. By analyzing three independent stories, students learn about usage, advantages and limitations of QF-PCR, and additionally gain knowledge in basic, pre-clinical and clinical sciences. This course is designated as an elective course for final year medical students who have completed either: a basic genetics course, a molecular genetics course, a biochemistry course or a molecular biology course. The focus of the classes is to draw students' attention to the possible application and rapid development of molecular biology techniques, which is the base for modern therapeutic and diagnostic strategies.

RESUMO

INTRODUCTION: Chronic hepatitis B virus (HBV) infection is associated with significant global morbidity and mortality. Low treatment rates are observed in patients living with HBV; the reasons for this are unclear. This study sought to describe patients' demographic, clinical and biochemical characteristics across three continents and their associated treatment need. METHODS: This retrospective cross-sectional post hoc analysis of real-world data used four large electronic databases from the United States, United Kingdom and China (specifically Hong Kong and Fuzhou). Patients were identified by first evidence of chronic HBV infection in a given year (their index date) and characterized. An algorithm was designed and applied, wherein patients were categorized as treated, untreated but indicated for treatment and untreated and not indicated for treatment based on treatment status and demographic, clinical, biochemical and virological characteristics (age; evidence of fibrosis/cirrhosis; alanine aminotransferase [ALT] levels, HCV/HIV coinfection and HBV virology markers). RESULTS: In total, 12,614 US patients, 503 UK patients, 34,135 patients from Hong Kong and 21,614 from Fuzhou were included. Adults (99.4%) and males (59.0%) predominated. Overall, 34.5% of patients were treated at index (range 15.9-49.6%), with nucleos(t)ide analogue monotherapy most commonly prescribed. The proportion of untreated-but-indicated patients ranged from 12.9% in Hong Kong to 18.2% in the UK; almost two-thirds of these patients (range 61.3-66.7%) had evidence of fibrosis/cirrhosis. A quarter (25.3%) of untreated-but-indicated patients were aged ≥ 65 years. CONCLUSION: This large real-world dataset demonstrates that chronic hepatitis B infection remains a global health concern; despite the availability of effective suppressive therapy, a considerable proportion of predominantly adult patients apparently indicated for treatment are currently untreated, including many patients with fibrosis/cirrhosis. Causes of disparity in treatment status warrant further investigation.

RESUMO

Although Warburg's discovery of intensive glucose uptake by tumors, followed by lactate fermentation in oxygen presence of oxygen was made a century ago, it is still an area of intense research and development of new hypotheses that, layer by layer, unravel the complexities of neoplastic transformation. This seemingly simple metabolic reprogramming of cancer cells reveals an intriguing, multi-faceted nature that may link various phenomena including cell signaling, cell proliferation, ROS generation, energy supply, macromolecules synthesis/biosynthetic precursor supply, immunosuppression, or cooperation of cancerous cells with cancer-associated fibroblasts (CAFs), known as reversed Warburg effect. According to the current perception of the causes and consequences of the Warburg effect, PI3K/Akt/mTOR are the main signaling pathways that, in concert with the transcription factors HIF-1, p53, and c-Myc, modulate the activity/expression of key regulatory enzymes, including PKM2, and PDK1 to tune in the most optimal metabolic setting for the cancer cell. This in turn secures adequate levels of biosynthetic precursors, NADPH, NAD+, and rapid ATP production to meet the increased demands of intensively proliferating tumor cells. The end-product of "aerobic glycolysis", lactate, an oncometabolite, may provide fuel to neighboring cancer cells, and facilitate metastasis and immunosuppression together enabling cancer progression. The importance and possible applicability of the presented issue are best illustrated by numerous trials with various agents targeting the Warburg effect, constituting a promising strategy in future anti-cancer regimens. In this review, we present the key aspects of this multifactorial phenomenon, depicting the mechanisms and benefits behind the Warburg effect, and also pointing to selected aspects in the field of anticancer therapy.

RESUMO

Pulse EPR measurements provide information on distances and distance distributions in proteins but require the incorporation of pairs of spin labels that are usually attached to engineered cysteine residues. In previous work, we demonstrated that efficient in vivo labeling of the Escherichia coli outer membrane vitamin B12 transporter, BtuB, could only be achieved using strains defective in the periplasmic disulfide bond formation (Dsb) system. Here, we extend these in vivo measurements to FecA, the E. coli ferric citrate transporter. As seen for BtuB, pairs of cysteines cannot be labeled when the protein is present in a standard expression strain. However, incorporating plasmids that permit an arabinose induced expression of FecA into a strain defective in the thiol disulfide oxidoreductase, DsbA, enables efficient spin-labeling and pulse EPR of FecA in cells. A comparison of the measurements made on FecA in cells with measurements made in reconstituted phospholipid bilayers suggests that the cellular environment alters the behavior of the extracellular loops of FecA. In addition to these in situ EPR measurements, the use of a DsbA minus strain for the expression of BtuB improves the EPR signals and pulse EPR data obtained in vitro from BtuB that is labeled, purified, and reconstituted into phospholipid bilayers. The in vitro data also indicate the presence of intermolecular BtuB-BtuB interactions, which had not previously been observed in a reconstituted bilayer system. This result suggests that in vitro EPR measurements on other outer membrane proteins would benefit from protein expression in a DsbA minus strain.

RESUMO

Air pollution has been a significant problem threatening human health for years. One commonly reported air pollutant is benzo(a)pyrene, a dangerous compound with carcinogenic properties. Values which exceed normative values for benzo(a)pyrene concentration in the air are often noted in many regions of the world. Studies on the worldwide spread of COVID-19 since 2020, as well as avian flu, measles, and SARS, have proven that viruses and bacteria are more dangerous to human health when they occur in polluted air. Regarding cyanobacteria and microalgae, little is known about their relationship with benzo(a)pyrene. The question is whether these microorganisms can pose a threat when present in poor quality air. We initially assessed whether cyanobacteria and microalgae isolated from the atmosphere are sensitive to changes in PAH concentrations and whether they can accumulate or degrade PAHs. The presence of B(a)P has significantly affected both the quantity of cyanobacteria and microalgae cells as well as their chlorophyll a (chl a) content and their ability to fluorescence. For many cyanobacteria and microalgae, an increase in cell numbers was observed after the addition of B(a)P. Therefore, even slight air pollution with benzo(a)pyrene is likely to facilitate the growth of airborne cyanobacteria and microalgae. The results provided an assessment of the organisms that are most susceptible to cellular stress following exposure to benzo(a)pyrene, as well as the potential consequences for the environment. Additionally, the results indicated that green algae have the greatest potential for degrading PAHs, making their use a promising bioremediation approach. Kirchneriella sp. demonstrated the highest average degradation of B(a)P, with the above-mentioned research indicating it can even degrade up to 80% of B(a)P. The other studied green algae exhibited a lower, yet still significant, B(a)P degradation rate exceeding 50% when compared to cyanobacteria and diatoms.

RESUMO

AIMS: To investigate characteristics of people hospitalized with coronavirus-disease-2019 (COVID-19) and diabetic ketoacidosis (DKA) or hyperosmolar hyperglycaemic state (HHS), and to identify risk factors for mortality and intensive care admission. MATERIALS AND METHODS: Retrospective cohort study with anonymized data from the Association of British Clinical Diabetologists nationwide audit of hospital admissions with COVID-19 and diabetes, from start of pandemic to November 2021. The primary outcome was inpatient mortality. DKA and HHS were adjudicated against national criteria. Age-adjusted odds ratios were calculated using logistic regression. RESULTS: In total, 85 confirmed DKA cases, and 20 HHS, occurred among 4073 people (211 type 1 diabetes, 3748 type 2 diabetes, 114 unknown type) hospitalized with COVID-19. Mean (SD) age was 60 (18.2) years in DKA and 74 (11.8) years in HHS (p < .001). A higher proportion of patients with HHS than with DKA were of non-White ethnicity (71.4% vs 39.0% p = .038). Mortality in DKA was 36.8% (n = 57) and 3.8% (n = 26) in type 2 and type 1 diabetes respectively. Among people with type 2 diabetes and DKA, mortality was lower in insulin users compared with non-users [21.4% vs. 52.2%; age-adjusted odds ratio 0.13 (95% CI 0.03-0.60)]. Crude mortality was lower in DKA than HHS (25.9% vs. 65.0%, p = .001) and in statin users versus non-users (36.4% vs. 100%; p = .035) but these were not statistically significant after age adjustment. CONCLUSIONS: Hospitalization with COVID-19 and adjudicated DKA is four times more common than HHS but both associate with substantial mortality. There is a strong association of previous insulin therapy with survival in type 2 diabetes-associated DKA.

RESUMO

The purpose of the presented article is to evaluate the students' perception of the online teaching educational model as a part of the "Biochemistry with Elements of Chemistry" course conducted during the COVID-19 pandemic at the Faculty of Medicine of the Jagiellonian University Medical College. The first part of the article reflects upon the pandemic impact on the transition from the in-person (standard format) to a complete remote learning format. The next part is based on the responses of the students to a questionnaire and presents an analysis of the students' preferences and perceptions regarding synchronous and asynchronous teaching methods. Students answered questions about the advantages and disadvantages of distance learning programs. They indicated the most suitable learning mode in terms of gaining knowledge and enhancing their motivation to learn. They listed factors that facilitated remote learning as well as those which made it difficult and posed a challenge to adjust to the new system, in all types of classes, that is, lectures, seminars, and laboratories. The last part of this paper presents the results of the students' performance in the pandemic-enforced system and compares them with the results from the previous class of students from the past year, when teaching was conducted mainly in the standard format. The conclusions from the given analysis may enable beneficial changes for the "Biochemistry with Elements of Chemistry" course for remote teaching in the future. It may also provide valuable insights for such types of courses conducted at other Universities and promote deliberations to continuously improve learning outcomes.

RESUMO

BACKGROUND: Patients with adjustable gastric banding (AGB) often require revision to one-stage or two-stage sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB). OBJECTIVE: To compare the long-term durability of revisional SG and RYGB, in terms of subsequent revision or conversion (RC). METHODS: The New York Statewide Planning and Research Cooperative Systems dataset was queried from 2006 to 2013 for patients who underwent primary SG and RYGB, one-stage, and two-stage conversion from AGB to SG and RYGB. Patients who required RC were identified. A multivariable Cox proportional hazard model was used to compare the RC risk among these groups. RESULTS: 13,749 had primary SG, 621 one-stage, and 321 two-stage AGB to SG. 31,814 had primary RYGB, 555 one-stage, and 248 two-stage AGB to RYGB. The estimated 5-year cumulative RC incidence rate was significantly lower after primary surgery than after prior AGB (one-stage AGB to SG 14.4%, two-stage AGB to SG 11.6%, primary SG 5.2%, one-stage AGB to RYBG 3.4%, two-stage AGB to RYGB 2.9%, and primary RYGB 1.1%, p-value < 0.0001). RYGB and SG did not differ significantly in terms of the elevation effect of one- and two-stage AGB conversion over primary surgeries (RYGB vs SG: one stage vs primary ratio of HR = 0.97, 95% CI = [0.58, 1.63], p-value = 0.9153; two stage vs primary ratio of HR = 1. 02, 95% CI = [0.50, 2.07], p-value = 0.9596). CONCLUSION: RC after AGB to SG or RYGB is more frequent compared to primary surgeries with procedures following AGB to SG being more common than AGB to RYGB. However, that difference was proportionally similar to the RC rate ratio differences noted for primary SG and RYGB.

RESUMO

Décrire les aspects épidémio-cliniques des manifestations thrombotiques au cours de la COVID-19 au sein des hôpitaux militaires de Libreville et Akanda, Gabon. Méthodes : Nous avons mené une étude rétrospective et descriptive multicentrique d'une durée de 7 mois, du 01er septembre 2021 au 31 mars 2022, portant sur les patients admis dans les unités de réanimation des hôpitaux d'instruction des armées de Libreville (HIAOBO) et d'Akanda (HIAA), pour COVID-19 documentée ou suspectée. Résultats : Durant la période d'étude, 167 patients ont été́ admis pour infection à SARS-CoV-2, parmi lesquels, 18 ont présentés des manifestations thromboemboliques (10,8%). La moyenne d'âge était de 54,7±6.4 ans. Il y avait une large prédominance masculine avec un sexe ratio à 2. Nous avons noté́ 9 cas d'embolie pulmonaire (50%), 5 cas d'accidents vasculaires cérébraux ischémiques (28%), 1 cas de thrombose veineuse profonde de membre inferieur (6%), 1 cas de thrombose veineuse cérébrale (6%), 1 cas de thrombose de la veine mésentérique (6%) et 1 cas de thrombose de la veine porte (6%). Les D-dimères étaient élevés chez tous les patients. Les globules blancs étaient élevés (>10000/mm3 ) chez 12 patients (67%). Les plaquettes étaient inférieures à 150000/mm3 pour 6 patients (33%). Tous les patients avaient une pneumonie à SARS-CoV-2 et la moyenne d'atteinte deslésions pulmonaires était estimée à 45%. Neuf patients étaient décédés (50%) au cours de l'hospitalisation. Conclusion : L'infection par le SARS-CoV-2 constitue vraisemblablement une prédisposition à la survenue d'un événement thrombotique. L'incidence des manifestations thrombotiques chez les patients atteints de COVID-19 reste élevée, renforçant ainsi la prescription systématique d'une anticoagulation prophylactique

RESUMO

OBJECTIVE: To determine the association between prescription of SGLT2 inhibitors (SGLT2is) and diabetic ketoacidosis (DKA) incidence or mortality in people with type 2 diabetes (T2D) hospitalized with COVID-19. RESEARCH DESIGN AND METHODS: This was a retrospective cohort study based on secondary analysis of data from a large nationwide audit from a network of 40 centers in the U.K. with data collection up to December 2020. The study was originally designed to describe risk factors associated with adverse outcomes among people with diabetes who were admitted to hospital with COVID-19. The primary outcome for this analysis was DKA on or during hospital admission. The secondary outcome was mortality. Crude, age-sex adjusted, and multivariable logistic regression models were used to generate odds ratios (ORs) and 95% CIs for people prescribed SGLT2i compared with those not prescribed SGLT2i. RESULTS: The original national audit included 3,067 people with T2D who were admitted to hospital with COVID-19, of whom 230 (7.5%) were prescribed SGLT2is prior to hospital admission. The mean age of the overall cohort was 72 years, 62.3% were men, and 34.9% were prescribed insulin. Overall, 2.8% of the total population had DKA and 35.6% of people in the study died. The adjusted odds of DKA were not significantly different between those prescribed SGLT2is and those not (OR 0.56; 95% CI 0.16-1.97). The adjusted odds of mortality associated with SGLT2is were similar in the total study population (OR 1.13; 95% CI 0.78-1.63), in the subgroup prescribed insulin (OR 1.02; 95% CI 0.59-1.77), and in the subgroup that developed DKA (OR 0.21; 95% CI 0.01-8.76). CONCLUSIONS: We demonstrate a low risk of DKA and high mortality rate in people with T2D admitted to hospital with COVID-19 and limited power, but no evidence, of increased risk of DKA or in-hospital mortality associated with prescription of SGLT2is.
