Correlation between Periodontitis and Gastritis Induced by Helicobacter pylori: A Comprehensive Review.

The goal of this comprehensive review was to verify if the prevalence of Helicobacter pylori (Hp) bacteria in patients with dyspepsia is higher in the oral cavity of periodontal or non-periodontal patients. The bibliographic search was conducted on scientific studies published in PubMed, Cochrane Library, SciELO, and BVS. The focus question was: "In patients with dyspepsia and periodontitis, is the prevalence of Hp bacteria in the oral cavity higher than in patients with only dyspepsia or without any disease?" The inclusion criteria were human studies in English, Portuguese, or Spanish languages, published between 2000 and 2022, that included patients over the age of 18 and aimed to evaluate the presence of Hp bacteria in the oral cavity and in the protective mucosal layer of the gastric lining of patients with the diseases (periodontitis and dyspepsia) or without disease; clinical trials, randomized controlled clinical trials, comparative studies, case-control studies, cross-sectional studies, and cohort studies. The methodological quality evaluation of the included articles was performed using the Joanna Briggs Institute tools. The final scores could be of "Low" quality (at least two "no" [red] or ≥ five "unclear" found), "Moderate" quality (one "no" [red] was found or up to four "unclear" criteria were met), or "High" quality (all green [yes] or at maximum two "unclear"). Of 155 potentially eligible articles, 10 were included in this comprehensive review after the application of the eligibility criteria. The selected studies were scrutinized regarding the relationship between Hp colonization in the oral cavity and stomach, its impact on severity and complications of gastric infection, as well as the effect of the presence of oral and gastric Hp on dental and systemic parameters. Hp can colonize periodontal pockets regardless of its presence in the stomach. There was a higher prevalence of oral biofilm in dyspeptic patients with periodontal disease, and worse control of bleeding and low oral hygiene was observed in periodontal compared to non-periodontal patients. For que quality assessment, the scientific studies included presented low to moderate methodological quality. Conclusions: It is possible to conclude that Hp is a bacterium that can colonize dental plaque independently of the stomach and vice versa; however, when both diseases are found, its presence may be more significant. Supra and subgingival dental plaque may be a reservoir of Hp, suggesting that patients with gastric infections are more likely to have Hp in the oral cavity. The results must be carefully analyzed due to the limitations present in this review.

Frequency and Risk Factors Associated with Prematurity: A Cohort Study in a Neonatal Intensive Care Unit.

Background/Objectives: Prematurity rates remain high and represent a challenge for the public health systems of any country, with a high impact on neonatal mortality. This study aimed to evaluate the frequency and environmental and maternal-fetal risk factors for premature birth in a cohort of parturient women, with their newborns monitored in a neonatal intensive care unit at a private reference hospital. Methods: A cohort was carried out between 2013 and 2018 among parturient women living in a capital city in the Northeast of Brazil whose newborns were admitted to the neonatal intensive care unit. This study was approved by the Research Ethics Committee of the University of Fortaleza. The information collected comprised data from both medical records and hydrosanitary data from maternal homes. Results: The prevalence of prematurity among live births (n = 9778) between 2013 and 2018 at this hospital was 23%. The frequency of prematurity among those eligible (n = 480) was 76.9%, and the frequency of eligible premature babies (n = 369) in relation to the total number of births in this period was 3.8%. In the multivariate analysis, the significant risk factors for prematurity were primigravida (RR = 1.104, 95%CI: 1.004-1.213) and hypertensive syndromes during pregnancy (RR = 1.262, 95%CI: 1.161-1.371), and the significant protective factor was the highest number of prenatal consultations (RR = 0.924, 95%CI: 0.901-0.947). Conclusions: This study contributes to providing greater visibility to prenatal care and the understanding of complications during pregnancy and childbirth care. These results indicate the need to implement public policies that promote improvements in the population's living conditions and care for pregnant women to reduce premature births and, consequently, neonatal and infant mortality.

Self-Perceived Quality of Life (WHOQOL-Bref), and Self-Reported Health, Social and Environmental Factors Related to Its Improvement among Residents of Anil, Rio de Janeiro-Cross-Sectional Study.

This study aims to assess the self-perception of the QoL (WHOQOL-bref) in the Canal of Anil zone and its neighbor zone of the center of the District of Anil in Rio de Janeiro and to identify which factors are associated with the population self-perception of the need to "improve" their quality of life (QoL). A cross-sectional observational analytical study was carried out after approval by the competent ethics committee (CEP/CONEP) approval. A non-probabilistic sampling of residents of the Canal of Anil (n = 494) and the central district of Anil (n = 250) was used. A questionnaire was administered in person to collect data on self-reported sociodemographic characteristics, general health, sanitation, lifestyle in the residential area, and the WHOQOL-Bref. Although with a worse self-perceived water/sanitation participants in the Anil Canal community report fewer allergies, less medication, fewer skin diseases, less Zika virus, and less Chikungunya, among others. The self-perception of the need to improve the QoL in the Anil Canal community and the zone at the central District of Anil has proved to be influenced by several social and economic factors as well as residential practices and conditions. The multivariate analysis allowed us to identify both modifiable and non-modifiable risk factors for the need to improve physical QoL: taking medication, respiratory problems, skin disease diagnosed by a doctor, having a water tank at home or having filtered water at home, unpleasant odor of the water of the Anil Canal and the level of education, and age. Regarding the need to improve the environmental QoL, both areas are largely modifiable (e.g., having had ascariasis/roundworm; having a water tank in the house; not drinking bottled water; not having pavements in the street). Sociodemographic and environmental factors, in addition to health conditions, play a pivotal role in influencing individuals' perceptions of the necessity for enhanced physical and environmental well-being.

Determinants of Neonatal and Postneonatal Mortality in Northeastern Brazil: A Cohort Study of Newborns Admitted to the Neonatal Intensive Care Unit.

Despite advances in neonatology, neonatal mortality from preventable causes remains high in the North and Northeast regions of Brazil. This study aimed to analyze the determinants associated with neonatal and postneonatal mortality in newborns admitted to a neonatal intensive care unit. A cohort study was carried out in a capital in the Brazilian Northeast from 2013 to 2018. The outcome studied was death. Poisson regression was performed in the multivariate analysis of variables. Four hundred and eighty newborns were eligible, and 8.1% (39 newborns) died. Among them, 34 died in the neonatal period. The determinants that remained significantly associated with neonatal and postneonatal mortality in the final adjustment model (p < 0.05) were history of abortion, perinatal asphyxia, early neonatal sepsis and umbilical venous catheterization. All causes of this outcome were preventable. The neonatal mortality rate, although it did not include twins, neonates with malformations incompatible with life and other conditions, was 3.47 deaths per thousand live births (95% CI:1.10-8.03‱), well below the national average. In this study, pregnant women from different social classes had in common a private plan for direct access to health services, which provided them with excellent care throughout pregnancy and postnatal care. These results indicate that reducing neonatal mortality is possible through public policies with strategies that promote improvements in access to health services.

Spina bifida, the normal, the pathological and the in-between: first evidence from a forensic osteological collection.

Spina bifida (SB), a rare congenital disorder, is often mentioned as an individualizing factor in Forensic Anthropology. A lack of empirical data regarding SB is noticed in the scientific literature. Moreover, within the scope of anthropological research on SB disparities in terminology, classification systems, and methodological approaches result in incomparable results. The wide range (1,2%-50%) of "spina bifida occulta" reported prevalences is a good example. This research aims to analyze and debate the standard diagnostic criteria of SB on human skeletal remains, and attempts to elaborate on an universal system, premised on the distinction between SB as a pathology, and cleft neural arch (CNA) as an anatomical variant, according to Barnes (1994, p. 360 [1). A study-base of 209 individuals (88 males; 121 females; 44-99 years old) from the 21st Century Identified Skeletal Collection from the University of Coimbra (CEI/XXI) was macroscopically analyzed, focusing on the sacrum and remaining vertebrae. Four individuals presented complete posterior opening of the sacral canal (2,6%[4/156]). The observed bone changes, combined with the analysis of the entire skeleton, indicate that CNA, rather than SB linked to a neural tube defect, is the most reliable explanation for these cases. Overall, CNA was observed on 11 skeletons (7.05% of 156). The viability and applicability of the developed methodology for the identification of SB/CNA in forensic and/or osteological contexts are discussed, as well as the possibility of a lower prevalence of SB occulta, in the general population, than speculated before. HIGHLIGHTS: • Spina bifida has been studied so far under different methodologies, classification systems and nomenclature, leading to unstandardized and incomparable data. • Spina bifida as a pathological manifestation of a neural tube defect, as opposed to cleft neural arch as a simple form of skeletal variation. • Both spina bifida and complete sacral cleft fit the criteria of an individualizing trait in Forensic Anthropology.

Oral health knowledge and attitude among healthcare professionals of long-term care units: a cross-sectional survey.

BACKGROUND: This study aims to evaluate the knowledge and the attitude in oral health (OH) of nurses (NUR) and auxiliary health technicians (AHT) belonging to the Long-term Care Units (LTC). METHODS: Observational cross-sectional study. A survey was applied in five MLTC in Porto (Portugal) to 145 healthcare works (HCW). Data were collected using structured questionnaires with questions about knowledge and attitude regarding oral care. Data analysis comparison was performed using non-parametric tests (α = 0.05). RESULTS: Out of a total of 259 HCW, 145 responses were obtained (55.98% response rate). The median number of correct answers was significantly different for NUR and AHT without oral health training (OHT) (p = .035).AHT with OHT had a significantly lower number of correct answers compared to NUR with OHT (7 vs. 9, p < .001). There was no significant difference in the number of correct answers in NUR with or without OHT (p = .391) and that the AHT without OHT have a median of correct answers significantly higher than those who they have OHT (8 vs. 7, p = .020) CONCLUSIONS: Despite the positive attitude of the HCW, the knowledge is scarce. HCW recognized the urgence to update the protocols. PRACTICAL IMPLICATIONS: Integrating dentists in the LTC team, implementation of OH protocols and providing OH training should be considered to bridge existing gaps.

MiR-138-5p Upregulation during Neuronal Maturation Parallels with an Increase in Neuronal Survival.

Neuronal maturation is a process that plays a key role in the development and regeneration of the central nervous system. Although embryonic brain development and neurodegeneration have received considerable attention, the events that govern postnatal neuronal maturation are less understood. Among the mechanisms influencing such neuronal maturation processes, apoptosis plays a key role. Several regulators have been described to modulate apoptosis, including post-transcriptional regulation by microRNAs. This study aimed to analyze endogenous expression changes of miR-138-5p, as well as its main validated pro-apoptotic target caspase3, during the maturation of neuronal cultures and their response under apoptotic challenge. Our results point out that the observed opposite expression of miR-138-5p and its target caspase3 might modulate apoptosis favoring neuronal survival at distinct maturation stages. The unchanged expression of miR-138-5p in mature neurons contrasts with the significant downregulation in immature neurons upon apoptotic stimulation. Similarly, immunoblot and individual cellular assays confirmed that during maturation, not only the expression but processing of CASP-3 and caspase activity is reduced after apoptotic stimulation which results in a reduction of neuronal death. Further studies would be needed to determine a more detailed role of miR-138-5p in apoptosis during neuronal maturation and the synergistic action of several microRNAs acting cooperatively on caspase3 or other apoptotic targets.

Does participation in the European Trauma Course lead to new behaviours and organisational change? A Portuguese experience.

BACKGROUND: Medical educational courses can be successful from an immediate feedback perspective but not lead to new behaviour or organisational changes in the workplace. The aim of this study was to assess the self-perceived impact of the European Trauma Course (ETC) on Reanima trainees' behaviour and organisational change. METHODS: A 40-item questionnaire based on Holton's evaluation model was used to evaluate the candidate's perceptions. The results were analysed with descriptive and inferential statistical analysis using nonparametric tests with α = 0.05. RESULTS: Out of 295 participants, 126 responded to the survey. Of these, 94% affirmed that the ETC modified their approach to trauma patients, and 71.4% described a change in their behaviour. Postcourse responders changed their behaviour in their initial approach to trauma care in the nontechnical skills of communication, prioritisation and teamwork. Being an ETC instructor strongly influenced the acquisition of new material, and this group was able to implement changes in attitudes. Individuals with no previous trauma course experience identified lack of self-efficacy as a significant obstacle to introducing new work-based learning. In contrast, responders with ATLS training noted a lack of ETC colleagues as the main impediment for moving from conceptualisation to experimentation in the workplace. CONCLUSIONS: Participation in the ETC led to behavioural changes in the workplace. However, the ability to influence others and bring about wider organisational changes was more difficult to achieve. Major factors were the status of the person, their experience and self-efficacy. National organisational impact was obtained, which went far beyond our aspirations in acknowledging change in individual daily practice. Future research studies will include the effect of implementing the ETC methodology on the outcome of trauma patients.

Evaluation of Poly(N-Ethyl Pyrrolidine Methacrylamide) (EPA) and Derivatives as Polymeric Vehicles for miRNA Delivery to Neural Cells.

MicroRNAs (miRNAs) are endogenous, short RNA oligonucleotides that regulate the expression of hundreds of proteins to control cells' function in physiological and pathological conditions. miRNA therapeutics are highly specific, reducing the toxicity associated with off-target effects, and require low doses to achieve therapeutic effects. Despite their potential, applying miRNA-based therapies is limited by difficulties in delivery due to their poor stability, fast clearance, poor efficiency, and off-target effects. To overcome these challenges, polymeric vehicles have attracted a lot of attention due to their ease of production with low costs, large payload, safety profiles, and minimal induction of the immune response. Poly(N-ethyl pyrrolidine methacrylamide) (EPA) copolymers have shown optimal DNA transfection efficiencies in fibroblasts. The present study aims to evaluate the potential of EPA polymers as miRNA carriers for neural cell lines and primary neuron cultures when they are copolymerized with different compounds. To achieve this aim, we synthesized and characterized different copolymers and evaluated their miRNA condensation ability, size, charge, cytotoxicity, cell binding and internalization ability, and endosomal escape capacity. Finally, we evaluated their miRNA transfection capability and efficacy in Neuro-2a cells and rat primary hippocampal neurons. The results indicate that EPA and its copolymers, incorporating ß-cyclodextrins with or without polyethylene glycol acrylate derivatives, can be promising vehicles for miRNA administration to neural cells when all experiments on Neuro-2a cells and primary hippocampal neurons are considered together.

Overexpression of the X-Linked Inhibitor of Apoptosis Protein (XIAP) in Neurons Improves Cell Survival and the Functional Outcome after Traumatic Spinal Cord Injury.

Mechanical trauma to the spinal cord causes extensive neuronal death, contributing to the loss of sensory-motor and autonomic functions below the injury location. Apoptosis affects neurons after spinal cord injury (SCI) and is associated with increased caspase activity. Cleavage of X-linked inhibitor of apoptosis protein (XIAP) after SCI may contribute to this rise in caspase activity. Accordingly, we have shown that the elevation of XIAP resulted in increased neuronal survival after SCI and improved functional recovery. Therefore, we hypothesise that neuronal overexpression of XIAP can be neuroprotective after SCI with improved functional recovery. In line with this, studies of a transgenic mice with overexpression of XIAP in neurons revealed that higher levels of XIAP after spinal cord trauma favours neuronal survival, tissue preservation, and motor recovery after the spinal cord trauma. Using human SH-SY5Y cells overexpressing XIAP, we further showed that XIAP reduced caspase activity and apoptotic cell death after pro-apoptotic stimuli. In conclusion, this study shows that the levels of XIAP expression are an important factor for the outcome of spinal cord trauma and identifies XIAP as an important therapeutic target for alleviating the deleterious effects of SCI.

Transanal Hemorrhoidal Dearterialization With Mucopexy Versus Vessel-Sealing Device Hemorrhoidectomy for Grade III to IV Hemorrhoids: Long-term Outcomes From the THDLIGA Randomized Controlled Trial.

BACKGROUND: Both transanal hemorrhoidal dearterialization and vessel-sealing device hemorrhoidectomy are safe for grade III to IV hemorrhoid treatment. Whether one of them is superior regarding long-term results remains unclear. OBJECTIVE: To compare long-term results after transanal hemorrhoidal dearterialization and vessel-sealing device hemorrhoidectomy. DESIGN: Multicenter randomized controlled trial. SETTINGS: This study was conducted at 6 centers. PATIENTS: Patients ≥18 years of age with grade III to IV hemorrhoids were included in the study. INTERVENTIONS: Patients were randomly assigned to transanal hemorrhoidal dearterialization (n = 39) or vessel-sealing device hemorrhoidectomy (n = 41). MAIN OUTCOME MEASURES: The primary outcome was hemorrhoid symptom recurrence assessed by a specific questionnaire 2 years postoperatively. Secondary outcomes included long-term complications, reoperations, fecal continence, and patient satisfaction and quality of life. RESULTS: Five of the 80 patients included in the study were lost to follow-up. Thirty-six patients randomly assigned to transanal hemorrhoidal dearterialization and 39 patients randomly assigned to vessel-sealing device hemorrhoidectomy were included in the long-term analysis. The differences between mean baseline and mean 2-year score in the 2 groups were similar (-11.0, SD 3.8 vs -12.5, SD 3.6; p = 0.080). Three patients in the transanal hemorrhoidal dearterialization group underwent supplementary procedures for hemorrhoid symptoms, compared with none in the vessel-sealing device hemorrhoidectomy group ( p = 0.106). Four patients in the vessel-sealing hemorrhoidectomy group and none in the transanal hemorrhoidal dearterialization group experienced chronic opened wound ( p = 0.116). LIMITATIONS: Lack of stratification for hemorrhoid grade and power calculation based on the main outcome trial but not on the end point of this long-term study. CONCLUSIONS: Transanal hemorrhoidal dearterialization with mucopexy is associated with hemorrhoid symptom recurrence similar to vessel-sealing device hemorrhoidectomy at 2 years.

DESARTERIALIZACIN HEMORROIDAL TRANSANAL CON MUCOPEXIA VERSUS HEMORROIDECTOMA CON DISPOSITIVO DE SELLADO DE VASOS PARA HEMORROIDES DE GRADO IIIIV RESULTADOS A LARGO PLAZO DEL ENSAYO CLNICO ALEATORIZADO THDLIGARCT: ANTECEDENTES:Tanto la desarterialización hemorroidal transanal como la hemorroidectomía con dispositivo de sellado de vasos son seguras y bien toleradas para el tratamiento de las hemorroides de grado III-IV. La primera se asocia con una necesidad más breve de analgesia posoperatoria que la hemorroidectomía con dispositivo de sellado de vasos. No está claro si uno de ellos es superior con respecto a los resultados a largo plazo.OBJETIVO:El objetivo fue comparar los resultados a largo plazo después de la desarterialización hemorroidal transanal y la hemorroidectomía con dispositivo de sellado de vasos.DISEÑO:Se realizó un ensayo clínico aleatorizado multicéntrico.AJUSTE:Este estudio se realizó en 6 centros.PACIENTES:Se incluyeron en el estudio pacientes de ≥18 años con hemorroides de grado III-IV.INTERVENCIONES:Los pacientes fueron asignados al azar a desarterialización hemorroidal transanal (n = 39) o hemorroidectomía con dispositivo de sellado de vasos (n = 41).PRINCIPALES MEDIDAS DE RESULTADO:El resultado primario fue la recurrencia de los síntomas de hemorroides evaluada mediante un cuestionario específico 2 años después de la operación. Los resultados secundarios incluyeron complicaciones a largo plazo, reoperaciones, continencia fecal, satisfacción del paciente y calidad de vida.RESULTADOS:Cinco de los 80 pacientes incluidos en el estudio se perdieron durante el seguimiento. En el análisis a largo plazo se incluyeron 36 pacientes aleatorizados a desarterialización hemorroidal transanal y 39 aleatorizados a hemorroidectomía con dispositivo de sellado de vasos. Las diferencias entre la puntuación inicial media y la puntuación media a los 2 años en los dos grupos fueron similares (-11,0, DE 3,8 frente a -12,5, DE 3,6; p = 0,080). Tres pacientes en el grupo de desarterialización hemorroidal transanal se sometieron a procedimientos complementarios por síntomas de hemorroides, en comparación con ninguno en el grupo de hemorroidectomía con dispositivo de sellado de vasos (p = 0,106). Cuatro pacientes en el grupo de hemorroidectomía con sellado de vasos y ninguno en el grupo de desarterialización hemorroidal transanal experimentaron herida abierta crónica (p = 0,116). No se encontraron diferencias en cuanto a continencia fecal (p = 0,657), satisfacción del paciente (p = 0,483) y calidad de vida.LIMITACIONES:No hay estratificación para el grado de hemorroides ni el cálculo del poder basado en el resultado principal del ensayo, pero no en el criterio de valoración de este estudio a largo plazo.CONCLUSIONES:La desarterialización hemorroidal transanal con mucopexia se asocia con una recurrencia de síntomas de hemorroides similar a la hemorroidectomía con dispositivo de sellado de vasos a los dos años.

Prevalence of dental floss use in deciduous dentition: A systematic review and meta-analysis.

OBJECTIVES: Adherence to the daily use of dental floss in childhood is recommended by various international health institutions/organizations. This systematic review (PROSPERO number CRD42020205232) aims to evaluate the prevalence of dental floss use in deciduous dentition. MATERIALS AND METHODS: A systematic review was conducted in six databases (B-on, Cochrane Library, PubMed, Scielo, Science Direct and Web of Science) up to December 2020. The CoCoPop mnemonic allowed for obtaining 2333 articles and resulted in the inclusion of 7 observational studies that evaluated the prevalence of dental floss use (primary outcome) in children up to 6 years old. The Joanna Briggs Institute critical appraisal checklist was used to evaluate the risk of bias, showing that most articles presented good quality. Meta-analyses were performed using the proportion of dental floss use (yes or once/day) and the random effects model. RESULTS: The meta-analysis showed a prevalence of dental floss use of only 12.60% (95% CI: 7.69%-18.52%) based on studies with high heterogeneity of results (I2  = 94.75%; 95% CI: 91.44%-96.78%). Six of the seven studies showed that more than 70% of children never used dental floss. CONCLUSIONS: A low prevalence of dental floss use was observed in children up to 6 years old. Given the diversity of evaluating the use of dental floss, different options should be the target of standardization in future studies.

MicroRNA-138-5p Targets Pro-Apoptotic Factors and Favors Neural Cell Survival: Analysis in the Injured Spinal Cord.

The central nervous system microRNA miR-138-5p has attracted much attention in cancer research because it inhibits pro-apoptotic genes including CASP3. We hypothesize that miR-138-5p downregulation after SCI leads to overexpression of pro-apoptotic genes, sensitizing neural cells to noxious stimuli. This study aimed to identify miR-138-5p targets among pro-apoptotic genes overexpressed following SCI and to confirm that miR-138-5p modulates cell death in neural cells. Gene expression and histological analyses revealed that the drop in miR-138-5p expression after SCI is due to the massive loss of neurons and oligodendrocytes and its downregulation in neurons. Computational analyses identified 176 potential targets of miR-138-5p becoming dysregulated after SCI, including apoptotic proteins CASP-3 and CASP-7, and BAK. Reporter, RT-qPCR, and immunoblot assays in neural cell cultures confirmed that miR-138-5p targets their 3'UTRs, reduces their expression and the enzymatic activity of CASP-3 and CASP-7, and protects cells from apoptotic stimuli. Subsequent RT-qPCR and histological analyses in a rat model of SCI revealed that miR-138-5p downregulation correlates with the overexpression of its pro-apoptotic targets. Our results suggest that the downregulation of miR-138-5p after SCI may have deleterious effects on neural cells, particularly on spinal neurons.

Assessing acceptability and identifying barriers and facilitators to implementation of the EULAR recommendations for patient education in inflammatory arthritis: a mixed-methods study with rheumatology professionals in 23 European and Asian countries.

OBJECTIVES: To disseminate and assess the level of acceptability and applicability of the European Alliance of Associations for Rheumatology (EULAR) recommendations for patient education among professionals in rheumatology across Europe and three Asian countries and identify potential barriers and facilitators to their application. METHODS: A parallel convergent mixed-methods design with an inductive approach was used. A web-based survey, available in 20 different languages, was distributed to health professionals by non-probability sampling. The level of agreement and applicability of each recommendation was assessed by (0-10) rating scales. Barriers and facilitators to implementation were assessed using free-text responses. Quantitative data were analysed descriptively and qualitative data by content analysis and presented in 16 categories supported by quotes. RESULTS: A total of 1159 completed the survey; 852 (73.5%) were women. Most of the professionals were nurses (n=487), rheumatologists (n=320), physiotherapists (n=158). For all recommendations, the level of agreement was high but applicability was lower. The four most common barriers to application were lack of time, lack of training in how to provide patient education, not having enough staff to perform this task and lack of evaluation tools. The most common facilitators were tailoring patient education to individual patients, using group education, linking patient education with diagnosis and treatment and inviting patients to provide feedback on patient education delivery. CONCLUSIONS: This project has disseminated the EULAR recommendations for patient education to health professionals across 23 countries. Potential barriers to their application were identified and some are amenable to change, namely training patient education providers and developing evaluation tools.

Barthel's Index: A Better Predictor for COVID-19 Mortality Than Comorbidities.

BACKGROUND: The most consistently identified mortality determinants for the new coronavirus 2019 (COVID-19) infection are aging, male sex, cardiovascular/respiratory diseases, and cancer. They were determined from heterogeneous cohorts that included patients with different disease severity and previous conditions. The main goal of this study was to determine if activities of daily living (ADL) dependence measured by Barthel's index could be a predictor for COVID-19 mortality. METHODS: A prospective cohort study was performed with a consecutive sample of 340 COVID-19 patients representing patients from all over the northern region of Portugal from October 2020 to March 2021. Mortality risk factors were determined after controlling for demographics, ADL dependence, admission time, comorbidities, clinical manifestations, and delay-time for diagnosis. Central tendency measures were used to analyze continuous variables and absolute numbers (proportions) for categorical variables. For univariable analysis, we used t test, chi-square test, or Fisher exact test as appropriate (α=0.05). Multivariable analysis was performed using logistic regression. IBM SPSS version 27 statistical software was used for data analysis. RESULTS: The cohort included 340 patients (55.3% females) with a mean age of 80.6±11.0 years. The mortality rate was 19.7%. Univariate analysis revealed that aging, ADL dependence, pneumonia, and dementia were associated with mortality and that dyslipidemia and obesity were associated with survival. In multivariable analysis, dyslipidemia (odds ratio [OR], 0.35; 95% confidence interval [CI], 0.17-0.71) was independently associated with survival. Age ≥86 years (pooled OR, 2.239; 95% CI, 1.100-4.559), pneumonia (pooled OR, 3.00; 95% CI, 1.362-6.606), and ADL dependence (pooled OR, 6.296; 95% CI, 1.795-22.088) were significantly related to mortality (receiver operating characteristic area under the curve, 82.1%; p<0.001). CONCLUSION: ADL dependence, aging, and pneumonia are three main predictors for COVID-19 mortality in an elderly population.

Green walls with recycled filling media to treat greywater.

The continuous growth of urban areas in the last decades has resulted in an increase in water consumption, contributing to larger volumes of urban and domestic wastewater. Thus, stakeholders have been seeking for efficient alternatives for wastewater management, namely looking for new forms of treatment and reuse. The present work provides new insights on the application of a green wall for greywater treatment, aiming at water reuse and also at contributing to Circular Economy. Two types of recycled materials, crushed tiles and textile fibers, were tested as filling media combined with two plant species. Crushed tiles were mixed with coconut fibers in a 70 %-30 % ratio and textile fibers were used as single media. The tiles+coconut mix with plants performed the best, exhibiting on average removal efficiencies >70 % for Chemical Oxygen Demand (COD) and between 59 %-70 % for Total Suspended Solids (TSS). Fibers systems had on average removal efficiencies around 60 % for COD and 50 % for TSS and clogged at the end of the study. Overall the study demonstrated that green walls for greywater treatment can contribute to circular economy through the use of recycled material as filling media.

miR-182-5p Regulates Nogo-A Expression and Promotes Neurite Outgrowth of Hippocampal Neurons In Vitro.

Nogo-A protein is a key myelin-associated inhibitor of axonal growth, regeneration, and plasticity in the central nervous system (CNS). Regulation of the Nogo-A/NgR1 pathway facilitates functional recovery and neural repair after spinal cord trauma and ischemic stroke. MicroRNAs are described as effective tools for the regulation of important processes in the CNS, such as neuronal differentiation, neuritogenesis, and plasticity. Our results show that miR-182-5p mimic specifically downregulates the expression of the luciferase reporter gene fused to the mouse Nogo-A 3'UTR, and Nogo-A protein expression in Neuro-2a and C6 cells. Finally, we observed that when rat primary hippocampal neurons are co-cultured with C6 cells transfected with miR-182-5p mimic, there is a promotion of the outgrowth of neuronal neurites in length. From all these data, we suggest that miR-182-5p may be a potential therapeutic tool for the promotion of axonal regeneration in different diseases of the CNS.

Disseminating and assessing implementation of the EULAR recommendations for patient education in inflammatory arthritis: a mixed-methods study with patients' perspectives.

OBJECTIVES: To explore patients' agreement and reasons for agreement or disagreement with the EULAR recommendations for patient education (PE) for people with inflammatory arthritis (IA). METHODS: This mixed-method survey collected data using snowball sampling. The survey had been translated into 20 languages by local healthcare professionals, researchers and patient research partners. It explored the degree to which patients with IA agreed with each recommendation for PE (0=do not agree at all and 10=agree completely) and their rationale for their agreement level in free text questions. Descriptive statistics summarised participants' demographics and agreement levels. Qualitative content analysis was used to analyse the free text data. Sixteen subcategories were developed, describing the reasons for agreement or disagreement with the recommendations, which constituted the categories. RESULTS: The sample comprised 2779 participants (79% female), with a mean (SD) age 55.1 (13.1) years and disease duration 17.1 (13.3) years. Participants strongly agreed with most recommendations (median 10 (IQR: 9-10) for most recommendations). Reasons for agreement with the recommendations included the benefit of using PE to facilitate collaborative care and shared decision making, the value of flexible and tailored PE, and the value of gaining support from other patients. Reasons for disagreement included lack of resources for PE, not wanting information to be tailored by healthcare professionals and a reluctance to use telephone-based PE. CONCLUSION: The EULAR recommendations for PE have been disseminated among patients with IA. Overall, agreement levels were very high, suggesting that they reflect patients' preferences for engaging in collaborative clinical care and using PE to facilitate and supplement their own understanding of IA. Reasons for not completely agreeing with the recommendations can inform implementation strategies and education of healthcare professionals.

Association between Environmental Cadmium Exposure and Osteoporosis Risk in Postmenopausal Women: A Systematic Review and Meta-Analysis.

Osteoporosis is a common and serious health issue among postmenopausal women. We conducted a systematic review and meta-analysis study to determine whether environmental exposure to cadmium (Cd) is a risk factor for postmenopausal osteoporosis. A PROSPERO-registered review of the literature was performed on studies evaluating the relationship between urinary Cd (UCd) concentration, an indicator of long-term Cd exposure, and bone mineral density or osteoporosis in women aged 50 years and older. PubMed, Embase, Science Direct, Web of Science, and B-on databases were searched for articles published between 2008 and 2021. The association between UCd levels and osteoporosis risk was assessed by pooled odds ratio (OR) and 95% confidence interval (CI) using random-effect models. Ten cross-sectional studies were included in the qualitative analysis, of which five were used for meta-analysis. We separately assessed the risk of osteoporosis in women exposed to Cd at low environmental levels (n = 5895; UCd ≥ 0.5 µg/g creatinine versus UCd < 0.5 µg/g creatinine) and high environmental levels (n = 1864; UCd ≥ 5 µg/g creatinine versus UCd < 5 µg/g creatinine). The pooled OR for postmenopausal osteoporosis was 1.95 (95% CI: 1.39−2.73, p < 0.001) in the low exposure level group and 1.99 (95% CI: 1.04−3.82, p = 0.040) in the high exposure level group. This study indicates that environmental Cd exposure, even at low levels, may be a risk factor for osteoporosis in postmenopausal women. Further research based on prospective studies is needed to validate these findings.
