[Salivary gland tumors: 2022 WHO blue book and beyond]. / Tumeurs des glandes salivaires : OMS 2022 et au-delà.

In 2022, the 5th edition of the WHO classification of Head and Neck tumors was published online. In the salivary gland chapter, a new benign entity, the keratocystoma, was introduced. The sclerosing polycystic adenosis has been recognized as tumoral and is now termed sclerosing polycystic adenoma. The striated duct adenoma now has its own dedicated chapter. Additionally, a new variant of pleomorphic adenoma, termed "canalicular adenoma-like," has been incorporated. Regarding malignant tumors of the salivary glands, significant doubts now exist regarding the actual existence of oncocytic carcinoma, which has been reclassified among emerging entities. Two new malignant entities have also emerged: microsecretory adenocarcinoma and microcystic sclerosing adenocarcinoma. Finally, primary mucinous adenocarcinoma of the salivary glands has been acknowledged as a distinct entity.

Enhancing CO catalytic oxidation performance over Cu-doping manganese oxide octahedral molecular sieves catalyst.

The CO oxidation catalytic activity of catalysts is strongly influenced by the oxygen vacancy defects (OVDs) concentration and the valence state of active metal. Herein, a defect engineering approach was implemented to enhance the oxygen vacancy defects and to modify the valence of metal ions in manganese oxide octahedral molecular sieves (OMS-2) by the introduction of copper (Cu). The characterization and theoretical calculation results reveal that the incorporation of Cu2+ ion into the OMS-2 structure led to a rise in specific surface area and pore volume, weakening of Mn-O bonds, higher proportion of the low-coordinated oxygen species adsorbed in oxygen vacancies (Oads) and an increase in the average oxidation state of manganese. These structural modifications were discovered to considerably reduce the apparent activation energy (Ea), thus ultimately significantly enhancing the CO oxidation activity (T99 at 148 ℃at GHSV = 13,200 h-1) than the original OMS-2 (T99 = 215 ℃ at GHSV = 13,200 h-1). Furthermore, In-situ diffuse reflectance infrared Fourier transform (DRIFT) and In-situ near-ambient pressure X-ray photoelectron spectroscopy (in situ NAP-XPS) results indicate that the bimetallic synergy enhanced by doping strategy accelerates the conversion of oxygen to chemisorbed oxygen species and the reaction rate of CO oxidation through Mn3++Cu2+↔Mn4++Cu+ redox cycle. The findings of this study offer novel perspectives on the design of catalysts with exceptional performance in CO oxidation.

Barriers to research among residents in oral and maxillofacial surgery.

PURPOSE/OBJECTIVES: Research is an integral part of oral and maxillofacial surgery (OMS) residency training. This study aimed to identify the current barriers perceived by OMS residents toward conducting research during training. METHODS: A cross-sectional, questionnaire-based study was conducted. The survey was distributed to 670 OMS residents across the United States in 2021 and consisted of questions regarding demographics, residency program requirements and resources, and perceived barriers to research. Data were analyzed using descriptive statistics, Fisher's exact tests, Kruskal-Wallis tests, and post hoc Dunn's test with a statistical significance of P < 0.05. RESULTS: The response rate was 24.2%. Most participants' programs had a minimum research requirement to complete a residency (80%). The top three reported barriers to completing research were lack of time (84%), limited access to research mentors or supervisors (37%), and lack of access to biostatistical support (31%). Factors associated with these barriers included the lack of a research director, supervisor, mentor, assistant, or statistician. There was no significant difference between residents in programs with protected research time versus those without. CONCLUSIONS: OMS residents generally viewed research experience during residency as beneficial but reported important barriers, most notably: insufficient time. Although most OMS training programs in the US require research for completion, many do not provide adequate time to facilitate this process. Compared with literature from over a decade ago, it appears little progress has been made to remedy similar barriers to research. Addressing this deficiency may increase the quantity and quality of research, furthering the profession.

Characterization of key aroma compounds in roasted chicken using SPME, SAFE, GC-O, GC-MS, AEDA, OAV, recombination-omission tests, and sensory evaluation.

Aroma compounds in the roasted breasts, thighs and skins of chicken were isolated by solvent-assisted flavor evaporation (SAFE), quantitated by gas chromatography-olfactometry-mass (GC-O-MS), analyzed by aroma extract dilution analysis (AEDA), and determined by recombination-omission tests and sensory evaluation. Forty-seven aroma compounds in total, including aldehydes, ketones, furans, pyrazines, and furanones, were selected by AEDA. Twenty-five compounds were selected as pivotal odorants (Odor Activity Value, OAV ≥ 1). Twenty aroma compounds significantly were identified by recombination and omission experiments. Anethole (fennel odor) was the highest OAV (＞ 1843). Hexanal (grassy) and (E, E)-2,4-decadienal (meaty) were the most abundant aldehydes identified in roasted chicken. 1-octen-3-ol (mushroom), methanethiol (cabbage) and dimethyl trisulfide (areca, sulfur) were considered the key compounds of the breast and thighs of roasted chicken. Notably, furanone and pyrazines, 4-hydroxy-5-methyl-3(2H)-furanone (caramel, sweet and burning odor), 3-ethyl-2,5-dimethylpyrazine (nutty, toasty) and 2,3-dimethyl-5-ethylpyrazine (nutty, toasty) had the most significant effect on roasted chicken odor, especially in the skin.

Unlocking peach juice byproduct potential in food waste biorefineries: Phenolic compounds profile, antioxidant capacity and fermentable sugars.

This work assesses an integrated pathway for the revalorization of peach byproduct (PB) within a biorefinery. PB was subjected to an oven-drying (OD) treatment for its evaluation as a storage treatment. It was compared to freeze-drying and untreated material in terms of antioxidant capacity (AOC), phenolic compounds (PC) profile and fermentable sugar production. OD reduced the water content to less than 15 % while preserving the bound hydrolysable polyphenols, which were the more abundant PC (≈64 %) with the highest AOC. Drying treatments hampered polysaccharide accessibility, but some enzyme preparations released 60-70 g/L of fermentable sugars at relatively high solids loading (10 %). This study proposes a novel enzyme-based strategy for the valorisation of fermentable sugars and antioxidant compounds from PB. The sugars can be fermented into several building blocks while the solid residue enriched in recalcitrant phenolic compounds and proteins could be used to develop novel functional products for food/feed sectors.

Vacinar ou arriscar? A mensagem da Organização Mundial de Saúde para promover a vacinação contra a covid-19 / Vaccinate or taking chances? The World Health Organization's message to promote vaccination against COVID-19

Resumo Centrando-se no impacto que a comunicação de risco emitida pelas organizações de saúde pública tem na mudança dos comportamentos da sociedade, esta investigação pretende analisar as mensagens-chave que a Organização Mundial de Saúde (OMS) definiu para promover o programa de vacinação contra a covid-19. Para cumprir este objetivo, enveredou-se por uma metodologia de estudo qualitativa, que privilegiou o uso da análise do conteúdo publicado nas páginas de Facebook e de Instagram da OMS, no período de 1 de abril a 31 de agosto de 2021. No total, foram analisadas 62 publicações. Os resultados mostraram que a OMS utilizou quatro eixo de comunicação para promover a importância da vacinação na sociedade: garantir a credibilidade e a transparência da informação transmitida; certificar a segurança e a eficácia da vacina; apelar ao sentido de responsabilidade coletiva; e associar a vacina à solução para pôr fim à pandemia. As conclusões do estudo mostram que, embora a equidade no acesso à vacina ainda seja uma realidade em construção, os quase 70% da população mundial vacinada sugerem que as mensagens enviadas pela OMS no contexto de comunicação de risco podem ter contribuído para a construção de uma imagem positiva do programa de vacinação.

Abstract Focusing on the impact that risk communication issued by public health organizations brings to changing societal behaviors, this research aimed to analyze the key messages that the World Health Organization (WHO) has defined to promote the COVID-19 vaccination program. In order to achieve this goal, a qualitative study methodology was used to analyze the content published on the WHO's Facebook and Instagram pages from April 1 to August 31, 2021. In total, 62 publications were analyzed. The results showed that the WHO used four key communication messages to promote the importance of vaccination in society: ensuring the credibility and transparency of the information transmitted; certifying the safety and efficacy of the vaccine; appealing to a sense of collective responsibility; and associating the vaccine with the solution to end the pandemic were the chosen communication axes. The conclusions of this study show that, although fair access to the vaccine is still a reality in the making, the fact that almost 70% of the world's population has been vaccinated suggests that the messages sent by the WHO in the context of risk communication may have contributed to building a positive image of the vaccination program.

Highly Active and Water-Resistant Cu-Doped OMS-2 Catalysts for CO Oxidation: The Importance of the OMS-2 Synthesis Method and Cu Doping.

Porous cryptomelane-type Mn oxide (OMS-2) has an outstanding redox property, making it a highly desirable substitute for noble metal catalysts for CO oxidation, but its catalytic activity still needs to be improved, especially in the presence of water. Given the strong structure-performance correlation of OMS-2 for oxidation reactions, herein, OMS-2 is synthesized by solid state (OMS-2S), reflux (OMS-2R), and hydrothermal (OMS-2H) methods, aiming to improve its CO oxidation performance through manipulating synthesis parameters to tailor its particle size, morphology, and crystallinity. Characterization shows that OMS-2S has the highest CO oxidation activity in the absence of water due to its low crystallinity, high specific surface area, large oxygen vacancy content, and good redox property, but the presence of water can greatly reduce its CO oxidation activity. Doping Cu into an OMS-2 can not only improve its CO oxidation activity but also greatly improve its water tolerance. The Cu-doped OMS-2S catalyst with ∼4 wt % Cu can achieve a T90 of 49 °C (1% CO/10% O2/N2 and WHSV = 60,000 mL·g-1·h-1), ranking among the lowest reported T90 values for Mn oxide-based CO oxidation catalysts, and it can maintain nearly 100% CO conversion in the presence of 5 vol % water for over 50 h. In situ DRIFTs characterization indicates that the good water resistance of Cu-doped OMS-2S can be attributed to the significantly suppressed surface hydroxyl group generation because of Cu doping. This work demonstrates the importance of the synthesis method and Cu doping in determining the CO oxidation activity and water resistance of OMS-2 and will provide guidance for synthesizing highly active and water-resistant CO oxidation catalysts.

[ICD-11: New revision and impact of this classification in psychiatry]. / CIM-11 (OMS) : nouvelle révision et impact de la classification onusienne en psychiatrie.

OBJECTIVES: After more than 20 years of work, the World Health Organization's efforts have culminated in the adoption of the 11th revision of the International Classification of Diseases (ICD-11). The process has been guided by the principles of global applicability, scientific validity, and clinical utility. The update of the chapter on mental, behavioral, and neurodevelopmental disorders (MBND) within the ICD-11 has generated widespread interest worldwide. This has raised various questions about the status of mental disorder nosology, changes to diagnostic guidelines, and the potential implications for clinical practice. METHODS: We conducted a narrative analysis of the literature in four different languages to track the various stages of the ICD-11 revision and to highlight the major changes. We searched databases such as PubMed, EMBASE, MEDLINE, and Google Scholar, and consulted the official websites of the WHO, APA, and UNICEF. A total of 79 articles from 40 different editorials and websites were analyzed and included in this study. RESULTS: The new chapters on mental disorders in the ICD-11 include 21 groups, as opposed to the 11 in the ICD-10. The changes aim to align the diagnoses with those of the DSM-5 and introduce a new chapter structure, new diagnostic categories, modifications to diagnostic criteria, and advancements in dimensionality. For the first time in the history of the ICD, sleep and wakefulness disorders, as well as disorders related to sexual health, have been addressed in separate chapters of the international classification. Four new diagnoses have been added: complex post-traumatic stress disorder (PTSD), gaming disorder, prolonged grief disorder, and compulsive sexual behavior which replaces "excessive sexual activity" in the ICD-10. Moreover, the ICD-11 revision has brought about a fundamental change in the clinical conceptualization of addictive behaviors, introducing a distinction between substance use disorders and addictive behaviors. The criteria for many existing conditions have been revised, particularly those related to bipolar disorders, eating disorders, and gender identity disorders. CONCLUSIONS: The revision process for mental, behavioral, and neurodevelopmental disorders in the ICD-11 has witnessed unprecedented participation in the history of mental disorder classification. These changes could have a significant impact on clinical practice in psychiatry. However, it is crucial to examine the advantages and limitations of this new classification compared to previous versions.

[Application of WHO 2015 nutritional profile model for the reduction of added sugars in children's dairy]. / Aplicación del modelo de perfiles nutricionales OMS 2015 para la reducción de azúcares añadidos en lácteos infantiles.

Introduction: In the last 20 years we have doubled obesity rates. In Spain, 67 % of the population does not have an adequate weight and 40 % of the child population suffers from obesity or overweight. This leads to serious diseases. To avoid this, a national plan to fight obesity is required, with prevention and therapeutic strategies so as not to continue increasing these data in 2030. Among the factors that cause childhood obesity are poor eating habits as well as a lack of physical activity and excessive use of screens. In addition, there is a significant social gap. Childhood obesity especially affects families with lower purchasing power (54 %) who do not have access to a healthy diet or the necessary tools or knowledge to promote health to their sons and daughters through food. The World Health Organization (WHO) Regional Office for Europe developed a nutrient profile model in 2015, specifically for the purpose of restricting the marketing of foods aimed at children. This model is considered by the scientific community as a reference tool when it comes to establish policies and improvements in favor of public health, in order to provide families with access to food with a better profile and nutritional value.

Introducción: En los últimos 20 años hemos duplicado las tasas de obesidad. Un 67 % de la población no tiene un peso adecuado y el 40 % de la población infantil sufre obesidad o sobrepeso en España. Esto deriva en graves enfermedades. Para evitarlo, es necesario un plan nacional de lucha contra la obesidad, con estrategias de prevención y terapéuticas para no seguir incrementando estos datos en 2030. Entre los factores causantes de la obesidad infantil se encuentran los malos hábitos de alimentación, además de la falta de actividad física y un uso excesivo de pantallas. Además, existe una brecha social importante. La obesidad infantil afecta especialmente a familias con menor poder adquisitivo (el 54 %), que no tienen acceso a una alimentación saludable ni las herramientas necesarias o el conocimiento para promover la salud a sus hijos e hijas a través de la alimentación. La Oficina Regional de la Organización Mundial de la Salud (OMS) para Europa desarrolló un modelo de perfil de nutrientes en 2015, específicamente a efectos de restringir la comercialización de alimentos dirigida a los niños, un modelo que se plantea desde la comunidad científica como una herramienta de referencia a la hora de establecer políticas y mejoras en pro de la salud pública, con el fin de facilitar a las familias el acceso a alimentos con un mejor perfil y valor nutricional.

In-person Versus Virtual Interviews in the Oral & Maxillofacial Surgery Residency Application Process: An Applicant Perspective.

PURPOSE: The purpose of this study is to determine whether in-person vs virtual interviews in the Oral & Maxillofacial Surgery (OMS) residency application process affects an applicant's perspective on a program and his/her comfort level in ranking a program. This study will also look to assess if the continuation of virtual interviews has any socioeconomic impacts on the application pool. METHODS: This cross-sectional study used a descriptive survey sent to all applicants in the 2022 to 2023 OMS residency application cycle to The Ohio State University OMS Residency Program (OSU OMS). The survey involved both scaled and comparative questions aimed to deduce applicant's preferences on the mode of interview process. Questions were designed to both target an applicant's ability to differentiate programs as well uncover any socioeconomic impacts that the reinstatement of in-person interviews caused. All obtained statistics were computed for data analysis. RESULTS: There were 187 applicants to the OSU OMS program in the 2022 to 2023 cycle. Fifty-four applicants completed responses (response rate = 28.9%). A total of 84.4% of respondents preferred in-person interviews. CONCLUSIONS: In-person interviews are the preferred modality for OMS interviews. The ability to experience a program and its faculty and residents in-person proved favorable despite the financial and logistical benefits of virtual interviews.

Psychometric properties of the Opening Minds Stigma Scale for Health Care Providers in 32 European countries - A bifactor ESEM representation.

Aims: To measure the stigma of healthcare providers toward people suffering from mental illness, the Opening Minds Stigma Scale for Health Care Providers (OMS-HC) is a commonly applied instrument. However, this scale has not been thoroughly validated in many European countries, its psychometric properties are still unknown and data on practicing psychiatrists is lacking. Therefore, this multicenter study aimed to assess the psychometric characteristics of the 15-item OMS-HC in trainees and specialists in adult and child psychiatry in 32 countries across Europe. Materials and methods: The OMS-HC was conducted as an anonymous online survey and sent via Email to European adult and child psychiatrists. Parallel analysis was used to estimate the number of OMS-HC dimensions. Separate for each country, the bifactor ESEM, a bifactor exploratory structural equation modeling approach, was applied to investigate the factor structure of the scale. Cross-cultural validation was done based on multigroup confirmatory factor analyses and reliability measures. Results: A total of 4,245 practitioners were included, 2,826 (67%) female, 1,389 (33%) male. The majority (66%) of participants were specialists, with 78% working in adult psychiatry. When country data were analyzed separately, the bifactor model (higher-order factor solution with a general factor and three specific factors) showed the best model fit (for the total sample χ2/df = 9.760, RMSEA = 0.045 (0.042-0.049), CFI = 0.981; TLI = 0.960, WRMR = 1.200). The average proportion of variance explained by the general factor was high (ECV = 0.682). This suggests that the aspects of 'attitude,' 'disclosure and help-seeking,' and 'social distance' could be treated as a single dimension of stigma. Among the specific factors, the 'disclosure and help-seeking' factor explained a considerable unique proportion of variance in the observed scores. Conclusion: This international study has led to cross-cultural analysis of the OMS-HC on a large sample of practicing psychiatrists. The bifactor structure displayed the best overall model fit in each country. Rather than using the subscales, we recommend the total score to quantify the overall stigmatizing attitudes. Further studies are required to strengthen our findings in countries where the proposed model was found to be weak.

Consenso SOCHOG/SOCHUMB: utilizar en Chile la curva estándar OMS ultrasonográfica de crecimiento fetal / SOCHOG/SOCHUMB consensus: OMS fetal ultrasound curve is the standard curve for ultrasound growth assessment to use in Chile

La Sociedad Chilena de Obstetricia y Ginecología (SOCHOG) y la Sociedad Chilena de Ultrasonido en Medicina y Biología (SOCHUMB) convocaron a un comité de expertos en el tema de ultrasonido y crecimiento fetal con el fin de proponer utilizar la curva fetal que mejor se adapte a la población chilena. Luego de la discusión, al no contar con curvas chilenas de crecimiento fetal, se concluye proponer que la curva estándar de la Organización Mundial de la Salud (OMS) sería la indicada dada la calidad de su metodología y por ser multicéntrica.

The Chilean Society of Obstetrics and Gynecology (SOCHOG) and the Chilean Society of Ultrasound in Medicine and Biology (SOCHUMB) have convened a committee of experts on the subject of ultrasound and fetal growth in order to propose using the fetal curve that best adapts to the Chilean population. After the discussion, since there are no Chilean fetal growth curves, it is concluded that the World Health Organization (WHO) standard curve would be the one to use given the quality of its methodology and the fact that it is multicentric.

Low attendance in cervical cancer screening, geographical disparities and sociodemographic determinants of screening uptake among adult women in Burkina Faso : results from the first nationwide population-based survey.

OBJECTIVE: To explore the level, geographical disparities and sociodemographic determinants of cervical cancer screening uptake among adult women in Burkina Faso by using data from the first national population-based survey. METHODS: This was a cross-sectional secondary analysis of primary data obtained by the 2013 World Health Organization (WHO) Stepwise Approach to Surveillance survey conducted in Burkina Faso. All 13 Burkinabè regions, with their different rates of urbanization, were surveyed. Lifetime cervical cancer screening uptake was explored. We included 2293 adult women for analyses and performed Student's t, chi-square and Fisher's exact tests, and logistic regression. RESULTS: Only 6.2% (95% CI: 5.3-7.3) of women had ever been screened for cervical cancer. For two regions ("Centre" and "Hauts-Bassins"), the pooled frequency was 16.6% (95% CI: 13.5-20.1) while in the other eleven regions it was significantly lower, 3.3% (95% CI: 2.5-4.2). In urban and rural areas, the respective frequencies for the screening uptake were 18.5% and 2.8% (p < 0.001), and in educated and un-educated women, frequencies were 27.7% and 3.3% (p < 0.001) respectively. The sociodemographic factors associated with screening uptake were being educated (adjusted odd-ratio [aOR] = 4.3; 95% CI: 2.8-6.7), urban residence (aOR = 3.8, 95% CI: 2.5-5.8) and having an occupation providing income (aOR = 3.1, 95% CI: 1.8-5.4). CONCLUSION: There was a significantly wide range in screening uptake between Burkina Faso regions, and the overall national as well as the region-specific levels were far below the WHO's target for cervical cancer elimination. Cervical cancer interventions should be tailored specifically for Burkinabè women with different educational levels, and prevention strategies based on community engagement integrating psychosocial considerations could be helpful.

Prognosis of thyroid carcinoma patients with osseous metastases: an SEER-based study with machine learning.

OBJECTIVE: Osseous metastasis (OM) is the second most common site of thyroid cancer distant metastasis and presents a poor prognosis. Accurate prognostic estimation for OM has clinical significance. Ascertain the risk factors for survival and develop an effective model to predict the 3-year, 5-year overall survival (OS) and cancer-specific survival (CSS) for thyroid cancer patients with OM. METHODS: We retrieved the information of patients with OMs between 2010 and 2016 from the Surveillance, Epidemiology, and End Result Program. The Chi-square test, and univariate and multivariate Cox regression analyses were performed. Four machine learning (ML) algorithms, which were most commonly used in this field, were applied. RESULT: A total of 579 patients having OMs were eligible. Advanced age, tumor size ≥ 40 mm, combined with other distant metastasis were associated with worse OS in DTC OMs patients. Radioactive iodine (RAI) significantly improved CSS in both males and females. Among four ML models [logistic regression, support vector machines, extreme gradient boosting, and random forest (RF)], RF had the best performance [area under the receiver-operating characteristic curve: 0.9378 for 3-year CSS, 0.9105 for 5-year CSS, 0.8787 for 3-year OS, 0.8909 for 5-year OS]. The accuracy and specificity of RF were also the best. CONCLUSIONS: RF model shall be used to establish an accurate prognostic model for thyroid cancer patients with OM, not only from the SEER cohort but also intended for all thyroid cancer patients in the general population, which may be applicable in clinical practice in the future.

Procedimiento de autorización de las vacunas contra la COVID-19: Estados Unidos de América, Unión Europea y América Latina / Authorization procedure for COVID-19 vaccines: United States of America, European Union and Latin America

Introducción: El reconocimiento de la enfermedad COVID-19 como pandemia, planteó un reto a las Autoridades Reguladoras Nacionales del Medicamento (ARNs). Éstas tuvieron que desarrollar pautas, procedimientos, crear grupos de trabajo y alianzas para maximizar la eficiencia de la evaluación, revisión y autorización de las vacunas. El objetivo del presente trabajo es la exposición de los procedimientos empleados en Estados Unidos, Unión Europea y América Latina para autorizar el uso de las vacunas frente a la COVID-19; y ello con el fin de determinar si la multiplicidad de procedimientos ha dado origen al registro de un elevado número de vacunas. Método: Se realizó una revisión de la legislación farmacéutica usada para la emisión de autorizaciones de las vacunas para la COVID-19, durante la emergencia sanitaria. La información fue recopilada hasta el 15/10/2022. Las fuentes consultadas fueron sitios web gubernamentales de las ARNs: Estados Unidos, Unión Europea y América Latina. Resultados: Los Estados Unidos y la Unión Europea usaron actividades consignadas en sus flujos estándares, tales como el pre-Investigational New Drug, y el asesoramiento científico y rolling review, respectivamente. Por su parte, América Latina, hizo uso extensivo del reliance y la autorización de uso de emergencia, con el fin de acceder al mayor número posible de vacunas. Conclusiones: Los procedimientos usados son diversos, pero todos ellos están orientados a proporcionar de manera rápida un producto de contención a la pandemia. Está diversidad da como resultado la presencia de distintas vacunas en Estados Unidos, Unión Europea y América Latina. (AU)

Introduction: The recognition of the COVID-19 disease as a pandemic posed a challenge to the National Drug Reg-ulatory Authorities (NRAs). They had to develop guidelines, procedures, create working groups and partnerships to maximize the efficiency of vaccine evaluation, review and licensure.The aim of this article is to present the procedures used in the United States, European Union and Latin America to license the use of vaccines against COVID-19; in order to determine whether the multiplicity of procedures has led to the registration of a large number of vaccines. Method: A review of the pharmaceutical legislation used for the issuance of COVID-19 vaccines licenses during the health emergency was carried out. The information was collected up to October 15, 2022. The sources consulted were government websites of the NRAs: United States, European Union, and Latin America. Results: The United States and the European Union used activities included in their standard flows, such as pre-In-vestigational New Drug, scientific advice and rolling review, respectively. Latin America, on the other hand, made extensive use of reliance and emergency use authorization in order to access as many vaccines as possible. Conclusions: The procedures used are diverse, but all of them are oriented to provide a rapid pandemic contain-ment product. This diversity results in the presence of different vaccines in the United States, European Union and Latin America. (AU)

Does Consulting an Occupational Medicine Specialist Decrease Time to Return to Work Among Total Knee Arthroplasty Patients? A 12-Month Prospective Multicenter Cohort Study.

PURPOSE: The aim of this study is to investigate whether total knee arthroplasty (TKA) patients who consulted an occupational medicine specialist (OMS) within 3 months after surgery, return to work (RTW) earlier than patients who did not consult an OMS. METHODS: A multi-center prospective cohort study was performed among working TKA patients, aged 18 to 65 years and intending to RTW. Time to RTW was analyzed using Kaplan Meier and Mann Whitney U (MWU), and multiple linear regression analysis was used to adjust for effect modification and confounding. RESULTS: One hundred and eighty-two (182) patients were included with a median age of 59 years [IQR 54-62], including 95 women (52%). Patients who consulted an OMS were less often self-employed but did not differ on other patient and work-related characteristics. TKA patients who consulted an OMS returned to work later than those who did not (median 78 versus 62 days, MWU p < 0.01). The effect of consulting an OMS on time to RTW was modified by patients' expectations in linear regression analysis (p = 0.05). A median decrease in time of 24 days was found in TKA patients with preoperative high expectations not consulting an OMS (p = 0.03), not in patients with low expectations. CONCLUSIONS: Consulting an OMS within 3 months after surgery did not result in a decrease in time to RTW in TKA patients. TKA patients with high expectations did RTW earlier without consulting an OMS. Intervention studies on how OMSs can positively influence a timely RTW, incorporating patients' preoperative expectations, are needed.

Catalytic destruction of chlorobenzene over K-OMS-2: Inhibition of high toxic byproducts via phosphate modification.

In the process of catalytic destruction of chlorinated volatile organic compounds (CVOCs), the catalyst is prone to chlorine poisoning and produce polychlorinated byproducts with high toxicity and persistence, bringing great risk to atmospheric environment and human health. To solve these problems, this work applied phosphate to modify K-OMS-2 catalysts. The physicochemical properties of catalysts were determined by using X-ray powder diffraction (XRD), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), hydrogen temperature programmed reduction (H2-TPR), pyridine adsorption Fourier-transform infrared (Py-IR) and water temperature programmed desorption (H2O-TPD), and chlorobenzene was selected as a model pollutant to explore the catalytic performance and byproduct inhibition function of phosphating. Experimental results revealed that 1 wt.% phosphate modification yielded the best catalytic activity for chlorobenzene destruction, with the 90% conversion (T90) at approximately 247°C. The phosphating significantly decreased the types and yields of polychlorinated byproducts in effluent. After phosphating, we observed significant hydroxyl groups on catalyst surface, and the active center was transformed into Mn(IV)-O…H, which promoted the formation of HCl, and enhanced the dechlorination process. Furthermore, the enriched Lewis acid sites by phosphating profoundly enhanced the deep oxidation ability of the catalyst, which promoted a rapid oxidation of reaction intermediates, so as to reduce byproducts generation. This study provided an effective strategy for inhibiting the toxic byproducts for the catalytic destruction of chlorinated organics.

Among the factors that cause childhood obesity are poor eating habits as well as a lack of physical activity and excessive use of screens.In addition, there is a significant social gap. Childhood obesity especially affects families with lower purchasing power (54 %) who do not have access to a healthy diet or the necessary tools or knowledge to promote health to their sons and daughters through food.The World Health Organization (WHO) Regional Office for Europe developed a nutrient profile model in 2015, specifically for the purpose of restricting the marketing of foods aimed at children. This model is considered by the scientific community as a reference tool when it comes to establish policies and improvements in favor of public health, in order to provide families with access to food with a better profile and nutritional value.

A captura ideológica dos mecanismos de participação social da OMS na negociação do acordo internacional sobre pandemias / The ideological capture of WHO's social participation mechanisms in the negotiation of the international pandemic agreement

Resumo Este artigo aborda a participação social nas negociações do acordo internacional sobre pandemias, conduzidas no âmbito da Organização Mundial da Saúde (OMS) por um Órgão Intergovernamental de Negociação (OIN). Apresenta resultados de pesquisa realizada por meio de revisão de literatura, pesquisa documental que abarcou mais de cem documentos do OIN, e pesquisa empírica que realizou a análise qualitativa dos conteúdos de 383 vídeos enviados pelo público durante a segunda fase de audiências públicas do OIN. A pesquisa confirma a hipótese de que houve captura ideológica das audiências públicas, entendida como a atuação concertada de indivíduos e organizações que, aproveitando-se de modalidades de participação abertas ao público, por meio de uma atuação massiva em prol de argumentos sem base científica ou inverificáveis, busca distorcer a finalidade das audiências públicas, transformando a consulta sobre o que deveria estar contido no acordo sobre pandemias em um espaço de difusão de sua agenda política. Apresenta, ainda, indícios de atuação concertada da extrema-direita contra o acordo. As conclusões defendem a necessidade de mudanças nesse mecanismo de participação, em prol de uma regulação da saúde global que leve em conta a opinião e os interesses dos seus principais destinatários.

Abstract This article addresses social participation in the negotiations of the international agreement on pandemics, conducted within the World Health Organization (WHO) by an Intergovernmental Negotiating Body (INB). It presents the results of research conducted with a literature review, document research that covered over 100 documents of the INB, and empirical research that carried out a qualitative analysis of the contents of 383 videos sent by the general public during the second phase of public hearings of the INB. The research confirms the hypothesis that there has been an ideological capture of the public hearings, understood as the concerted action of individuals and organizations that, by taking advantage of participation modalities open to the general public, with a massive action in favor of unscientific or unverifiable arguments, have sought to distort the purpose of social participation, turning the public consultation on what should be included in the agreement on pandemics into a space for the dissemination of their political agenda. It also presents evidence of concerted action by far-right groups against the agreement. The conclusions point to the need for changes in this participation mechanism, in favor of a regulation of global health that considers the opinion and interests of its main recipients.
