Desempenho da atenção primária à saúde no estado de São Paulo, Brasil, no período de 2010-2019 / Performance of primary health care in São Paulo state, Brazil, during the period 2010-2019

Resumo O artigo apresenta uma análise do desempenho da APS no estado de São Paulo na última década, em contexto de crise econômica e retração dos investimentos em saúde. Utilizaram-se indicadores de desempenho, determinantes em saúde e sistema de saúde, em série temporal (2010 a 2019), a partir de matriz conceitual adaptada. Foram calculadas variações percentuais anuais (VPA) de cada indicador em modelo log-linear. Os indicadores de desempenho apresentaram, no geral, evolução favorável; no entanto, ocorreu piora em indicadores relacionados à qualidade do cuidado (sífilis congênita, partos cesáreos e rastreamento de câncer de colo uterino). Verificou-se, ainda, um potencial aumento das demandas ao SUS (envelhecimento da população e redução da cobertura da saúde suplementar) e aumento das despesas em saúde em contexto de redução do PIB per capita.

Abstract This article presents the results of an analysis of the performance of primary health care in São Paulo state over the last decade against a backdrop of financial crisis and health funding cuts. We conducted a time series analysis (2010-2019) of performance indicators across the following dimensions based on an adapted conceptual framework: health service performance, health system, and determinants of health. Annual percentage change was calculated for each indicator using a log-linear model. Performance across the indicators was generally positive; however, there was a decline in performance across indicators of quality of care (congenital syphilis, cesarean section rate and cervical cancer screening). The findings also show a potential rise in demand for public services (due to population aging and a reduction in the percentage of the population with private health insurance) and increase in health expenditure against a backdrop of falling GDP per capita.

The effectiveness of mapping-targeted biopsies on the index lesion in transperineal prostate biopsies

ABSTRACT Purpose: To evaluate the effectiveness of mapping-targeted biopsies (MTB) on the index lesion for the detection of clinically significant prostate cancer (csPCa) in transperineal fusion-image prostate biopsies. Materials and Methods: A retrospective analysis was conducted on 309 men with suspected PCa who underwent prostate biopsies at the Creu Blanca reference center in Barcelona, Spain. The Prostate Imaging-Reporting and Data System (PI-RADS v.2.1) of the magnetic resonance images (MRI) were reclassified by an expert radiologist reading of pre-biopsy biparametric MRI used for segmentation of suspected lesions. Transperineal MTB of suspicious lesions and 12-core systematic biopsies were performed using the Artemis™ platform. CsPCa was defined as International Society of Urological Pathology grade group ≥ 2. Results: CsPCa was detected in 192 men (62.1%), with detection rates of 6.3% for PI-RADS 2, 26.8% for PI-RADS 3, 87.3% for PI-RADS 4, and 93.1% for PI-RADS 5. MTB of the index lesion identified 185 csPCa (96.3%). CsPCa was detected solely in systematic biopsies in three cases (1.6%), while an additional four cases (2.1%) were identified only in the second suspected lesion. A predictive model for csPCa detection in MTB of the index lesion was developed, with an AUC of 0.918 (95% CI 0.887-0.950). Conclusions: This model had the potential to avoid 23.3% of prostate biopsies without missing additional csPCa cases. MTB of the index lesion was highly effective for identifying csPCa in fusion transperineal prostate biopsies. A developed predictive model successfully reduced the need for almost one quarter of biopsies without missing csPCa cases.

Evaluación de la consistencia interna y dimensionalidad de la Escala de Capital Social Cognitivo en adultos colombianos

Introducción: durante las últimas dos décadas, el concepto de capital social se ha utilizado con creciente frecuencia en las ciencias de la salud debido a las relaciones directas e indirectas entre el capital social y la salud física y mental de las poblaciones. Por tanto, es necesario construir un instrumento para cuantificar este concepto con seguridad y confiabilidad. Objetivo: analizar la consistencia interna y dimensionalidad de una escala de siete ítems para medir el capital social en adultos de la población general de Colombia. Metodología: se realizó un estudio de validación en línea, que incluyó una muestra de 700 adultos de entre 18 y 76 años, el 68 % eran mujeres. Los participantes completaron una escala de siete ítems llamada Escala de Capital Social Cognitivo (ECSC). El alfa de Cronbach y el omega de McDonald se calcularon para probar la consistencia interna. Se realizaron análisis factoriales exploratorios y confirmatorios para explorar la dimensionalidad de la ECSC. Resultados: la ECSC presentó una consistencia interna baja (alfa de Cronbach de 0,56 y omega de McDonald de 0,59) y pobre dimensionalidad. Seguidamente, se probó una versión de cinco ítems (ECSC-5). La ECSC-5 mostró una alta consistencia interna (alfa de Cronbach de 0,79 y omega de McDonald de 0,80) y una estructura unidimensional con indicadores de bondad de ajuste aceptables. Discusión: la ECSC-5 presenta alta consistencia interna y una estructura unidimensional para medir el capital cognitivo social en adultos colombianos. Se recomienda la ECSC-5 para la medición del capital social en la población general colombiana. Futuras investigaciones deben corroborar estos hallazgos en aplicaciones de lápiz y papel y explorar otros indicadores de confiabilidad y validez.

Introduction: During the last two decades, the concept of social capital has been used increasingly frequently in health sciences due to the direct and indirect relationships between social capital and populations' physical and mental health. Therefore, it is necessary to build an instrument to quantify this concept confidently and reliably. Objective: The study aimed to internal consistency and dimensionality of a seven-item scale to measure social capital in Colombia's general population of adults. Methods: An online validation study included a sample of 700 adults aged between 18 and 76 years; 68% were females. Participants completed a seven-item scale called the Cognitive Social Capital Scale (CSCS). Cronbach's alpha and McDonald's omega were computed to test internal consistency. The authors explore the internal consistency and dimensionality of the CSCS. Results: The CSCS presented a low internal consistency (Cronbach's alpha of 0.56 and McDonald's omega of 0.59) and poor dimensionality. Then, the researchers tested a five-item version (CSCS-5). The CSCS-5 showed high internal consistency (Cronbach's alpha of 0.79 and McDonald's omega of 0.80) and a one-dimension structure with acceptable goodness-of-fit indicators. Discussion: The CSCS-5 presents high internal consistency and a one-dimensional structure to measure cognitive capital social in the Colombian sample. Authors can recommend measuring social capital in the general Colombian population. Further research should corroborate this pencil and paper application findings and explore other reliability and validity indicators.

Seguimiento de niños con diagnóstico de asma grave antes y durante la pandemia por COVID-19 / Follow-up of children diagnosed with severe asthma before and during the COVID-19 pandemic

En la pandemia por COVID-19 se exploraron estrategias de atención para garantizar el seguimiento de niños con asma grave. Estudio prospectivo, observacional, comparativo. Se incluyeron pacientes del programa de asma grave de un hospital pediátrico de tercer nivel (n 74). Se evaluó el grado de control, exacerbaciones y hospitalizaciones durante un período presencial (PP), marzo 2019-2020, y uno virtual (PV), abril 2020-2021. En el PP, se incluyeron 74 pacientes vs. 68 (92 %) del PV. En el PP, el 68 % (46) de los pacientes presentaron exacerbaciones vs. el 46 % (31) de los pacientes en el PV (p 0,003). En el PP, se registraron 135 exacerbaciones totales vs. 79 en el PV (p 0,001); hubo una reducción del 41 %. En el PP, el 47 % (32) de los pacientes tuvieron exacerbaciones graves vs. el 32 % (22) de los pacientes en el PV (p 0,048). Hubo 91 exacerbaciones graves en el PP vs. 49 en el PV (p 0,029), reducción del 46 %. No hubo diferencias en las hospitalizaciones (PP 10, PV 6; p 0,9). La telemedicina fue efectiva para el seguimiento de pacientes con asma grave

During the COVID-19 pandemic, health care strategies were explored to ensure the follow-up of children with severe asthma. This was a prospective, observational, and comparative study. Patients in the severe asthma program of a tertiary care children's hospital were included (n: 74). The extent of control, exacerbations, and hospitalizations during an in-person period (IPP) (March 2019­2020) and an online period (OP) (April 2020­2021) was assessed. A total of 74 patients were enrolled in the IPP compared to 68 (92%) in the OP. During the IPP, 68% (46) of patients had exacerbations versus 46% (31) during the OP (p = 0.003). During the IPP, 135 total exacerbations were recorded compared to 79 during the OP (p = 0.001); this accounted for a 41% reduction. During the IPP, 47% (32) of patients had severe exacerbations versus 32% (22) during the OP (p = 0.048). A total of 91 severe exacerbations were recorded during the IPP compared to 49 during the OP (p = 0.029); the reduction was 46%. No differences were observed in terms of hospitalization (IPP: 10, OP: 6; p = 0,9). Telemedicine was effective for the follow-up of patients with severe asthma.

Persistencia de signos y síntomas a los 6 meses posinfección por chikungunya en pacientes de un hospital público en Paraguay

Introducción: El virus chikungunya (CHIKV) causa una enfermedad con manifestaciones agudas bien documentadas, pero existen pocos datos sobre la persistencia de síntomas y secuelas a largo plazo. Objetivos: Evaluar la persistencia de signos, síntomas y factores asociados en pacientes con infección por CHIKV en un seguimiento de 6 meses posinfección. Materiales y métodos: Estudio de cohorte ambispectivo que incluyó casos confirmados de CHIKV notificados en abril de 2023 en Coronel Oviedo, Paraguay. Se realizaron entrevistas al mes, a los tres meses y a los 6 meses posinfección. Se analizaron características demográficas, comorbilidades, manifestaciones reumáticas y sintomáticas. Resultados: Ingresaron 333 participantes, completando seguimiento a 6 meses 170 pacientes. A los 6 meses persistieron: dolor de espalda (61.2%), artritis (57.1%), cefalea (54.1%), fatiga (51.2%), mialgia (49.4%), debilidad (47.6%), depresión (45.9%) y artralgia (45.9%). La persistencia de artritis (OR 7.54; p=0.008) y mialgia (OR 3.24; p=0.031) a 6 meses fue mayor en el grupo de 36-45 años. Conclusiones: Alta persistencia de síntomas musculoesqueléticos y fatiga hasta 6 meses posinfección, con tendencia decreciente, pero exacerbación de depresión. Edad entre 36-45 años asociada a mayor persistencia. Se requieren protocolos de seguimiento integral, investigar mecanismos fisiopatológicos y fortalecer prevención, dado el impacto individual y socioeconómico de la enfermedad.

Introduction: Chikungunya virus (CHIKV) causes a disease with well-documented acute manifestations, but there is limited data on the persistence of symptoms and long-term sequelae. Objectives: To evaluate the persistence of signs, symptoms, and associated factors in patients with CHIKV infection during a 6-month post-infection follow-up. Material and Methods: An ambispective cohort study that included confirmed cases of CHIKV reported in April 2023 in Coronel Oviedo, Paraguay. Interviews were conducted at 1, 3 and 6 months post-infection. Demographic characteristics, comorbidities, rheumatic, and symptomatic manifestations were analyzed. Results: 333 participants were enrolled, with 170 patients completing the 6-month follow-up. At 6 months, the following symptoms persisted: back pain (61.2%), arthritis (57.1%), headache (54.1%), fatigue (51.2%), myalgia (49.4%), weakness (47.6%), depression (45.9%), and arthralgia (45.9%). The persistence of arthritis (OR 7.54, p=0.008) and myalgia (OR 3.24, p=0.031) at 6 months was higher in the 36-45 age group. Conclusions: High persistence of musculoskeletal symptoms and fatigue up to 6 months post-infection, with a decreasing trend but exacerbation of depression. Age between 36-45 years was associated with greater persistence. Comprehensive follow-up protocols, investigation of pathophysiological mechanisms, and strengthening prevention are required, given the individual and socioeconomic impact of the disease.

Investigación cualitativa en el contexto de la Salud Pública: actualización de conceptos

Los enfoques cualitativos en la investigación han sido fundamentales en las ciencias sociales y son cruciales para el estudio de la salud y los servicios sanitarios. Con el progreso en medicina, mayor especialización, expectativas crecientes de los pacientes y la complejidad de los servicios de salud, los profesionales se enfrentan a un entorno laboral cada vez más complicado. Los métodos cualitativos, aunque distintos de las técnicas experimentales y cuantitativas de la investigación clínica y biomédica, son indispensables para la investigación en servicios de salud. Esto se debe a que permiten explorar aspectos no medibles cuantitativamente, como las creencias sobre la salud, y porque proporcionan una base -descriptiva necesaria para la investigación cuantitativa, especialmente en campos con escasa investigación previa.

Qualitative approaches in research have been fundamental in the social sciences and are crucial to the study of health and health services. With progress in medicine, greater specialization, increasing patient expectations and the complexity of health services, professionals face an increasingly complicated work environment. Qualitative methods, although different from the experimental and quantitative techniques of clinical and biomedical research, are essential for health services research. This is because they allow us to explore aspects that are not quantitatively measurable, such as beliefs about health, and because they provide a necessary descriptive basis for quantitative research, especially in fields with little previous research.

Seguimiento Funcional hasta Seis Meses después de Sobrevivir a Cuidados Intensivos: Lecciones aprendidas de un Estudio Chileno Multicéntrico / Functional follow-up six months after surviving intensive care: lessons learned from a Chilean multicenter study

Introducción. Las tasas de retención en los estudios de seguimiento oscilan entre el 32 y 100%, demostrando el desafío que implica realizar estudios longitudinales de sobrevivientes de la unidad de cuidados intensivos (UCI). Objetivo. Identificar las estrategias implementadas y lecciones aprendidas en un estudio prospectivo multicéntrico de seguimiento de sobrevivientes de la UCI durante la pandemia. Métodos. Estudio post-hoc de las lecciones aprendidas mediante encuestas y entrevistas dirigidas a explorar la experiencia de los investigadores y coordinadores del estudio IMPACCT COVID-19, realizado en siete centros chilenos entre octubre 2020 y abril 2021 evaluando el síndrome post-cuidados intensivos de sobrevivientes hasta seis meses después. Resultados. Identificamos ocho lecciones: 1) selección de instrumentos de medición, 2) identificación de centros participantes, 3) aprobación del estudio, 4) financiamiento, 5) capacitación de evaluadores, 6) coordinación/aseguramiento de calidad, 7) reclutamiento y 8) seguimiento de pacientes. Incluso durante el primer año de pandemia, reclutamos 252 pacientes a una tasa de 1,4 pacientes/día con una retención del 48% a los 6 meses de seguimiento. El uso de redes académicas existentes y las estrategias de comunicación entre investigadores, coordinadores y evaluadores fueron aspectos positivos; mientras que la fidelización con evaluadores al egreso de la UCI y con pacientes durante el seguimiento son aspectos que deberían considerarse en futuros estudios. Conclusiones. Se evaluaron más de 250 pacientes en seis meses durante la pandemia, con tasas de retención post UCI acorde a la literatura. Futuros estudios debiesen optimizar los procesos de medición y de seguimiento para minimizar la pérdida de pacientes.

Background. Retention rates of follow-up studies range from 32 to 100%, demonstrating the challenge to conduct longitudinal studies of intensive care unit (ICU) survivors. Objective. To identify the strategies implemented and lessons learned in a multicenter prospective follow-up study of ICU survivors during pandemic times. Methods. Post-hoc study of lessons learned through surveys and interviews aimed at exploring the experience of the researchers and coordinators of the IMPACCT COVID-19 study. The original study was performed in seven Chilean sites between October 2020 and April 2021 evaluating the post-intensive care syndrome of survivors up to six-month follow-up. Results. We identified eight lessons: 1) selection of measurement instruments, 2) identification of participating sites, 3) Study approval, 4) funding, 5) evaluators training, 6) coordination/quality assurance, 7) recruitment, and 8) patient follow-up. Even during the first year of the pandemic, we recruited 252 patients at a rate of 1.4 patients/day with a retention rate of 48% at 6 months of follow-up. The use of existing academic networks and communication strategies between researchers, coordinators and evaluators were positive aspects; while evaluators fidelity at ICU discharge and patient engagement during follow-up are aspects should be considered. Conclusions. More than 250 patients were evaluated in six months during the pandemic, with post-ICU retention rates consistent with the literature. Future studies should optimize measurement and monitoring processes to minimize patient atrition.

Estudos culturais físicos e feminismo: relações entre corpo, gênero e justiça social / Physical cultural studies and feminism assemblage: relationships between body, gender and social justice

Buscamos reconhecer como conhecimentos feministas contribuem para (re)interpretações teórico-metodológicas, a partir da produção de pesquisas/intervenções relacionadas à gênero no contexto da cultura física. Alicerçados numa abordagem qualitativa, selecionamos textos feministas dos Estudos Culturais Físicos. Como resultado, argumentamos que os textos exploram formas de teorizar gênero e as múltiplas operações do poder social a partir da radicalidade do corpo como local central dessas relações; apontam para a autorreflexidade exercida pelas pesquisadoras ao narrarem suas experiências em pesquisas; e, acenam para o imperativo político como base para a mudança social progressiva, engajando-se com questões que transcendem a categoria "gênero".

We seek to recognize how feminist knowledge contributes to theoreticalmethodological (re)interpretations, based on the production of research/interventions related to gender in the context of physical culture. Based on a qualitative approach, we selected feminist texts from Physical Cultural Studies. As a result, we argue that the texts explore ways of theorizing gender and the multiple operations of social power based on the radicality of the body as the central location of these relationships; point to the self-reflexivity exercised by the researchers when narrating their research experiences; and, they point to the political imperative as a basis for progressive social change, engaging with issues that transcend the "gender" category.

Drugs and natural products for the treatment of COVID-19 during 2020, the first year of the pandemic / Fármacos y productos naturales para el tratamiento de la COVID-19 durante 2020, el primer año de la pandemia

Abstract This work aimed to show which treatments showed efficacy against coronavirus disease 2019 (COVID-19); therefore, the results of 37 clinical trials started in 2020 and completed in 2021 are reviewed and discussed here. These were selected from databases, excluding vaccines, computational studies, in silico, in vitro, and those with hyperimmune sera from recovered patients. We found 34 drugs, one vitamin, and one herbal remedy with pharmacological activity against symptomatic COVID-19. They reduced mortality, disease progression, or recovery time. For each treatment, the identifier and type of trial, the severity of the disease, the sponsor, the country where the trial was conducted, and the trial results are presented. The drugs were classified according to their mechanism of action. Several drugs that reduced mortality also reduced inflammation in the most severe cases. These include some that are not considered anti-inflammatory, such as Aviptadil, pyridostigmine bromide, anakinra, imatinib, baricitinib, and bevacizumab, as well as the combination of ivermectin, aspirin, dexamethasone, and enoxaparin. Nigella sativa seeds with honey have also been reported to have therapeutic activity. On the other hand, tofacitinib, novaferon with ritonavir, and lopinavir were also effective, as well as in combination with antiviral therapies such as danoprevir with ritonavir. The natural products colchicine and Vitamin D3 were only effective in patients with mild-to-moderate COVID-19, as was hydroxychloroquine. Drug repositioning has been the main tool in the search for effective therapies by expanding the pharmacological options available to patients.

Resumen El objetivo del presente trabajo fue conocer qué tratamientos mostraron efectividad contra COVID-19, para lo cual se revisan y discuten los resultados de 37 estudios clínicos iniciados durante 2020 y concluidos en 2021. Estos fueron seleccionados de bases de datos, excluyendo vacunas, estudios computacionales, in silico, in vitro y con sueros hiperinmunes de pacientes recuperados. Se documentaron 34 fármacos, una vitamina y un remedio herbolario, con actividad farmacológica ante COVID-19 sintomático. Estos redujeron la mortalidad, el progreso de la enfermedad, o el tiempo de recuperación. Para cada tratamiento se presenta identificador y tipo de estudio, la gravedad de la enfermedad, patrocinador, país donde se realizó, así como sus resultados. Los fármacos se clasificaron de acuerdo con su mecanismo de acción. Varios fármacos que redujeron la mortalidad también disminuyeron la inflamación en los casos más graves. Esto incluyendo algunos no considerados antiinflamatorios, como el aviptadil, el bromuro de piridostigmina, el anakinra, el imatinib, el baricitinib y el bevacizumab, así como la combinación de ivermectina, aspirina, dexametasona y enoxaparina. También se reportaron con actividad terapéutica las semillas de Nigella sativa con miel. Además, resultaron efectivos el tofacitinib, el novaferón con ritonavir y lopinavir, así como los antivirales en terapias combinadas como el danoprevir con ritonavir. Los productos naturales colchicina y vitamina D3, solo tuvieron actividad en los pacientes en estado leve a moderado de la COVID-19, así como la hidroxicloroquina. El reposicionamiento de fármacos fue la principal herramienta para buscar terapias efectivas ampliando las opciones farmacológicas accesibles a los pacientes.

New candidate SNPs for genetic association with Alzheimer's disease: a linkage disequilibrium analysis for the FCGRIIB and PILRA genes

Background Two new SNPs have been recently associated to Alzheimer's disease in African American populations: FCGRIIB rs1050501 C/T, and PILRA rs1859788 A/G. The risk of Alzheimer's disease in FCGRIIB C and PILRA A allele carriers is three times higher than in non-carriers. However, the association between these and other single nucleotide polymorphisms (SNPs) has not been assessed. Methods Linkage disequilibrium analysis, with r= 0.8 as a threshold value, was used to impute new candidate SNPs, on genomic data from both genes in 26 populations worldwide (n= 2504) from the 1000Genomes database. Results Four SNPs (rs13376485, rs3767640, rs3767639 and rs3767641) were linked to rs1050501 and one (rs2405442) to rs1859788 in the whole sample. Conclusions Five novel SNPs could be associated with Alzheimer's disease susceptibility and play a causal role, even if none of them are exon variants since their potential roles in the regulation of gene expression.

Antecedentes Recientemente se han asociado dos nuevos polimorfismos de un solo nucleótido (SNP) a la enfermedad de Alzheimer en poblaciones afroamericanas: FCGRIIB rs1050501 C/T, y PILRA rs1859788 A/G. El riesgo de enfermedad de Alzheimer en los portadores de los alelos FCGRIIB C y PILRA A es tres veces mayor que en los no portadores. Sin embargo, no se ha evaluado la asociación entre estos y otros SNP. Métodos Se utilizó el análisis de desequilibrio de ligamiento, con r2= 0,8 como valor umbral, para imputar nuevos SNPs candidatos, sobre datos genómicos de ambos genes en 26 poblaciones de todo el mundo (n= 2504) de la base de datos 1000Genomes. Resultados Cuatro SNPs (rs13376485, rs3767640, rs3767639 y rs3767641) se vincularon al rs1050501 y uno (rs2405442) al rs1859788 en toda la muestra. Conclusiones Cinco nuevos SNP podrían estar asociados con la susceptibilidad a la enfermedad de Alzheimer y desempeñar un papel causal, aunque ninguno de ellos sea una variante de exón, dado su papel potencial en la regulación de la expresión génica.

Latin American Forensic Odontology: A Scoping Review of its Current Research and the Objective/Subjective Nature of its Studies

SUMMARY: The new paradigm in Forensic Sciences initiated by the entry of genetics (the current standard of legal evidence) and accentuated by recognized wrongful convictions derived from experts today in the eye of criticism, has highlighted the potential for bias and error in forensic disciplines when they depend on human interpretation and subjectivity, which has not been avoided by Forensic Odontology (FO). However, a subjective judgment is not necessarily wrong, so the refinement of processes, the development of standards, and robust research can contribute to the validity of interpretation to increase objectivity. Latin America (LATAM) has its own realities and needs, which have conditioned the priorities and objectives of FO research. A scoping review is presented to systematically map the investigation of LATAM researchers and identify the objective or subjective nature of their assessments. LATAM shows interesting productivity and intentions to adhere to international standards, with Brazil leading this research significantly, followed by Chile and Colombia, among others. However, there is a disproportionate approach in certain lines of research (dental age estimation), and needs to address other quantitative studies, and to improve the visibility of the LATAM FO research.

El nuevo paradigma en ciencias forenses iniciado por la entrada de la genética (el actual estándar de la evidencia jurídica), y acentuado por reconocidas condenas injustas derivadas de pericias hoy en el ojo de la crítica, ha destacado el potencial de sesgo y error que poseen algunas disciplinas forenses cuando dependen de la interpretación humana y la subjetividad, lo cual no ha sido ajeno a la odontología forense (OF). Sin embargo, un juicio subjetivo no necesariamente es erróneo, con lo que el refinamiento de procesos, el desarrollo de estándares y la investigación robusta pueden contribuir a validar esa interpretación para aumentar su objetividad. Latinoamérica (LATAM) posee realidades y necesidades propias que han condicionado las prioridades y objetivos de la investigación en OF. Se presenta una revisión con búsqueda sistemática para mapear sistemáticamente la investigación en OF realizada por investigadores latinoamericanos, así como identificar la naturaleza objetiva o subjetiva de sus evaluaciones. LATAM demuestra una productividad interesante e intenciones de adherirse a estándares internacionales, con Brasil liderando significativamente esta investigación, seguido por Chile y Colombia entre otros. Sin embargo, se observa un enfoque desproporcionado en ciertas líneas de investigación (estimación de edad dental particularmente), y necesidad tanto de abordar otros estudios cuantitativos como de mejorar la visibilidad de la investigación latinoamericana en OF.

La educación basada en la comunidad desde las percepciones de estudiantes: un estudio cualitativo / Community-Based Education from the students' perceptions: a qualitative study

Introducción. La Universidad del Norte Santo Tomás de Aquino (UNSTA) presenta como nueva oferta de grado la carrera de medicina, que enfatiza un enfoque orientado a la familia y la comunidad. El programa de estudio incorpora la educación basada en la comunidad (EBC), desde el primer al último ciclo de la carrera. Objetivos. Indagar acerca de las percepciones que los estudiantes que cursaron el primer año de medicina en la UNSTA tienen acerca de sus experiencias en EBC y caracterizar la valoración que le otorgan al contacto precoz con la comunidad. Material y métodos. Estudio cualitativo, paradigma hermenéutico. Modo de generación conceptual, método de análisis de la teoría fundamentada a partir de entrevistas en profundidad. Resultados. Según la percepción de estudiantes, la EBC permite abrir la cabeza (descubrir otras realidades, chocarse con otros contextos, construir otra idea de médico); significa nutrirse de la práctica temprana (tener una marca para toda la carrera, salirse del libro, aprender de la salud pública local, conocer a un esencial invisible, valorar los diagnósticos de situación locales, sentirse parte y ponerse el delantal); posibilita aprender más allá de la medicina (generar un estudio más reflexivo, vivir el trabajo en equipo, mejorar las habilidades comunicacionales, entender a la persona como un todo e iniciar un compromiso social). Conclusiones. Los hallazgos subrayan los numerosos beneficios de un plan de estudio que integre la EBC desde el principio. No solo fomenta el aprendizaje reflexivo, sino que también facilita un proceso clínico centrado en la persona y su contexto, iniciando así un compromiso social. (AU)

Background. Universidad del Norte Santo Tomás de Aquino (UNSTA) introduces a new medicine degree program. The graduate profile will be that of a general practitioner with family and community orientation. The study program incorporates community-based education (CBE) from the first to the last cycle of the program. Objectives. To investigate the perceptions that students who completed the first year of medicine at UNSTA have about their experiences at CBE and to characterize the value they give to early contact with the community. Material and methods. Qualitative study, hermeneutic paradigm, conceptual generation mode, grounded theory analysis based on in-depth interviews. Results. According to the perception of students, CBE allows us to open our minds (to discover other realities, encounter other contexts, and build another idea of a medical doctor); it means being nourished by early practice (having a mark for the entire career, going outside the book, learning from local public health, getting to know an invisible essential, valuing local situation diagnoses, feeling a part and putting on the apron); it makes it possible to learn beyond medicine (to generate a more reflective study, to experience teamwork, to improve communication skills, to understand the person as a who leand to initiate a social commitment). Conclusions. Our findings underscore the numerous benefits of a study plan that integrates CBE from the outset. It not only fosters reflective learning but also facilitates a clinical process that is centered on the individual and their environment, thereby initiating a social commitment. (AU)

Meta-analysis of the efficacy of invisible orthodontic appliances for maxillary molar distalization in adult patients / 口腔疾病防治

Objective@#To evaluate the clinical efficacy of invisible orthodontic appliances without brackets for the distal movement of maxillary molars to improve the ability of orthodontists to predict treatment outcomes.@*Methods@#Web of Science, Cochrane Library, Embase, PubMed, Wanfang Database, CNKI Database, and VIP Database were searched for studies investigating the efficacy of invisible orthodontic appliances for distal movement of maxillary molars in adult patients and published from database inception to August 1, 2023. A total of three researchers screened the studies and evaluated their quality and conducted a meta-analysis of those that met quality standards.@*Results@#This study included 13 pre- and postcontrol trials with a total sample size of 281 patients. The meta-analysis revealed no significant differences in the sagittal or vertical parameters of the jawbone after treatment when compared with those before treatment (P>0.05). The displacement of the first molar was MD=-2.34, 95% CI (-2.83, -1.85); the displacement was MD=-0.95, 95% CI (-1.34, -0.56); and the inclination was MD=-2.51, 95% CI (-3.56, -1.46). There was a statistically significant difference in the change in sagittal, vertical, and axial tilt of the first molar before and after treatment. After treatment, the average adduction distance of the incisors was MD=-0.82, 95% CI (-1.54, -0.09), and the decrease in lip inclination was MD=-1.61, 95% CI (-2.86, -0.36); these values were significantly different from those before treatment (P<0.05).@*Conclusion@#Invisible orthodontic appliances can effectively move the upper molars in a distal direction and control the vertical position of the molars. When the molars move further away, there is some degree of compression and distal tilt movement, which is beneficial for patients with high angles. The sagittal movement of incisors is beneficial for improving the patient's profile.

Influence of triglyceride/high-density lipoprotein cholesterol ratio on the onset of primary liver cancer / 临床肝胆病杂志

ObjectiveTo investigate the influence of triglyceride （TG）/high-density lipoprotein cholesterol （HDL-C） ratio on the onset of primary liver cancer. MethodsA prospective cohort study was conducted. Physical examination data were collected from 99 750 cases of on-the-job and retired employees of Kailuan Group who participated health examination from July 2006 to December 2007， and they were followed up till December 31， 2021 to observe the onset of primary liver cancer. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the Kruskal-Wallis H test was used for comparison of continuous data with skewed distribution between multiple groups； the chi-square test was used for comparison of categorical data between groups. According to the tertiles of TG/HDL-C ratio， the subjects were divided into Q1， Q2， and Q3 groups， and the incidence density of primary liver cancer was calculated for each group. The Kaplan-Meier method was used to calculate the cumulative incidence rate of primary liver cancer in each group， and the log-rank test was used to compare the difference in cumulative incidence rate between groups. The Cox proportional hazards model was used to analyze the influence of TG/HDL-C ratio on the onset of primary liver cancer. ResultsThere were significant differences between the three groups in age， proportion of male subjects， waist circumference， body mass index， fasting blood glucose， systolic pressure， diastolic pressure， triglyceride， total cholesterol， HDL-C， low-density lipoprotein cholesterol， alanine aminotransferase， high-sensitivity C-reactive protein， chronic liver diseases， hypertension， diabetes， the family history of malignant tumor， drinking， smoking， physical exercise， and educational level （P<0.05）. During the mean follow-up time of 14.06±2.71 years， there were 484 cases of new-onset liver cancer， among whom there were 446 male subjects and 38 female subjects. The incidence density of primary liver cancer was 0.39/1 000 person-years in the Q1 group， 0.35/1 000 person-years in the Q2 group， and 0.30/1 000 person-years in the Q3 group， and the cumulative incidence rates of primary liver cancer in the three groups were 6.03‰， 5.28‰， and 4.49‰， respectively， with a significant difference between the three groups based on the long-rank test （χ2=6.06， P=0.048）. After adjustment for the confounding factors considered， the Cox proportional hazards model showed that compared with the Q3 group， the Q1 group had a hazard ratio of 2.04 （95% confidence interval ［CI］： 1.61‍ ‍—‍ ‍2.58， Pfor trend<0.05）， and the Q2 group had a hazard ratio of 1.53 （95%CI： 1.21‍ ‍—‍ ‍1.92， Pfor trend<0.05）. ConclusionThe reduction in TG/HDL-C ratio is associated with an increase in the rask of primary liver cancer， especially in people with chronic liver diseases.

Relationship between physical activity levels and depressive symptoms in college students: a cohort study / 中国学校卫生

Objective@#To explore the association between physical activity levels and depressive symptoms among college students, so as to provide evidence for promoting physical and mental health of college students.@*Methods@#Using a cohort study design,a baseline survey of 1 415 college students in Shenyang Normal University in 2017 followed for three years from 2018 to 2020. The International Physical Activity Questionnaire-Short Form (IPAQ-SF) and Selfrating Depression Scale (SDS) were used to evaluate the physical activity levels and depressive symptoms of college students. According to the level of physical activity at baseline (MET ·h/week), participants were divided into three groups [T1 (≤36.4), T2 (>36.4-89.3) and T3 (>89.3)]. Logistic regression analysis was used to examine the association between baseline physical activity levels and the incidence of depressive symptoms during the school years.@*Results@#In the 3year followup (2018-2020), 852 (60.2%) participants exhibited depressive symptoms. The numbers of individuals with depressive symptoms in the T1, T2, and T3 groups were 324, 268, and 260, respectively. Logistic regression analysis showed that college students who participated in higher levels of physical activity decreased the risk of depressive symptoms by 34.2% [T2: OR(95%CI) = 0.658 (0.500-0.866)] and 38.9% [T3:OR(95%CI)=0.611(0.465-0.804)] compared with T1 group after adjusting for demographic, lifestyle, healthrelated factors, and baseline depressive symptoms as covariates. The sexstratified analysis showed a negative correlation between physical activity levels and the incidence of depressive symptoms in female college students. Compared with T1 group, higher levels of physical activity reduced the incidence of depressive symptoms by 39.6% [T2: OR(95%CI)=0.604(0.445-0.820)] and 37.7% [T3: OR(95%CI)=0.623(0.459-0.846)], respectively (P<0.01). However, there was no significant correlation between physical activity levels and depressive symptoms in male college students (P>0.05).@*Conclusions@#There is an inverse relationship between physical activity levels and depressive symptoms. The findings suggest that schools should reduce the risk of depressive symptoms by promoting physical activity levels among college students.

OBJECTIVE To systematically evaluate the real-world effectiveness and safety of belimumab in the treatment of lupus nephritis （LN） in Chinese adult patients. METHODS Retrieved from PubMed， Embase， Web of Science， Cochrane Library， Wanfang data， CNKI， VIP and CBM， real-world studies on belimumab in the treatment of LN in Chinese adult patients were collected from the inception to July 7th， 2023. Two reviewers independently screened the literature， extracted data， and assessed the quality of the included studies. Meta-analysis was then performed using RevMan 5.3 software. RESULTS A total of 10 real- world studies were included， involving 253 Chinese adult patients with LN. The results of the meta-analysis demonstrated that the complete renal response rate， partial renal response rate， and the incidence of adverse reaction rate in Chinese adult patients with LN treated with belimumab were 61% （95%CI was 46%-76%， P＜0.000 01）， 23%（95%CI was 2%-44%， P＝0.03）， and 30% （95%CI was 16%-43%， P＜0.000 01）， respectively. Belimumab could reduce the 24-hour urinary protein （MD＝－1.71， 95%CI was －3.02-－0.40， P＝0.01）， urine protein-creatinine ratio （MD＝－1.76，95%CI was －2.06-－1.46，P＜0.000 01）， the systemic lupus erythematosus disease activity index （MD＝－8.63， 95%CI was －12.12-－5.13， P＜0.000 01）， and glucocorticoids dosage （MD＝－18.65， 95%CI was －31.82-－5.48， P＝0.006）. In addition， it could elevate the levels of complement C3 （MD＝0.19， 95%CI was 0.08-0.30， P＝0.000 6） and complement C4 （MD＝0.06， 95%CI was 0.02-0.09， P＝0.001）. However， belimumab could not improve the levels of serum creatinine and estimated glomerular filtration rate （P＞0.05）. CONCLUSIONS Belimumab has good efficacy and safety in Chinese adult patients with LN.

Effectiveness of comprehensive sexuality education curriculum on improving hostile and benevolent sexism among university students / 中国学校卫生

Objective@#To explore the effectiveness of a comprehensive sexuality education (CSE) curriculum on university students hostile and benevolent sexism, so as to provide a reference for evaluating the effects of CSE on reducing ambivalent sexism.@*Methods@#From September 2018 to January 2019, 165 university students from a university in Beijing were recruited using convenience sampling for a 5 month of CSE curriculum (36 sessions, 2 sessions per week, 45 min per session), including CSE and gender studies, sexual physiology and health, gender and gender roles, gender bias, intimate relationships and gender bias, gender based violence and gender bias, culture and gender bias, and gender and power. Students who took CSE curriculum were included in the intervention group ( n =97) and students from the same university who had not taken CSE curriculum were included in the control group ( n =68). Using the Ambivalent Sexism Inventory, both groups of university students were surveyed before and after the curriculum to analyze the effectiveness of the CSE curriculum. Chi -square test, ANOVA，cluster analysis and Kruskal Wallis test were used for statistical analysis.@*Results@#After the CSE curriculum, both hostile and benevolent sexism scores were lower in the intervention group (2.21±0.76, 2.36±0.68) than in the control group (2.81±0.61, 3.03±0.60) ( F =17.24, 33.26), and pre test scores were higher in the intervention group (2.64±0.67, 2.88±0.68) ( F =45.62, 66.93) ( P <0.01). On both hostile and benevolent sexism, female students scores (2.46±0.72, 2.65±0.70) were lower than male students scores (2.86±0.59, 3.09± 0.69 ) ( F=11.02, 14.20, P <0.01). Comparison of the curriculum effectiveness of hostile and benevolent sexism among clustered groups showed that the difference in hostile sexism scores was higher in the inconsistent type [0.63(0.25, 1.25)]than in the more consistent type [0.38(-0.16, 0.88)] and the lower consistent type [0.38(0.06, 0.63)] ( H=8.71, P <0.05); and the difference in benevolent sexism scores was higher in the more consistent type [0.75(0.53, 1.22)] than in the less consistent type [0.38(0.09, 0.88 )] and inconsistent type [0.38(-0.13,0.63)] ( H=10.82, P <0.05).@*Conclusions@#CSE can improve hostile and benevolent sexism in university students with sex and type differences. Attention should be paid to CSE curriculum to improve ambivalent sexism among university students with a view to fostering their awareness of gender equality.

Intervention effects of moderate and high intensities of classroom physical activity on cardiorespiratory fitness and executive function among junior grade one students in Tibetan / 中国学校卫生

Objective@#To explore the intervention effect of different intensity of classroom physical exercise on cardiorespiratory fitness and executive function of Tibetan first grade students at high altitude, so as to provide reference for improving the level of cardiorespiratory fitness and executive function of Tibetan adolescents.@*Methods@#From September to December 2020, 184 Tibetan students from five first grade classes in a middle school in Lhasa, Tibet, were randomly assigned into a control group (81 students in two classes) and an intervention group (103 students in three classes). Both groups followed the same teaching programme, but the intervention group received 36 sessions of moderate to high intensity classroom physical activity, one session per day, Monday,Wednesday and Friday, for 12 weeks. Before and after the intervention, cardiorespiratory fitness and executive function were tested by 20m round trip running and Flanker s experimental paradigm, 2-back s experimental paradigm, and More odd shifting experimental paradigm for inhibitory control, refreshing memory, and switching flexibility, and the results were analysed by analysis of covariance (ANCOVA) to compare the results of the pre and post intervention periods.@*Results@#The maximum oxygen uptake (VO 2max ) of Tibetan first grade students in the intervention group increased by 2.25 mL/(kg〖WW）〗·〖WW(〗min) compared with the control group after the intervention ( t =-3.89, P <0.01); the response time of the inhibitory function was reduced by 4.40 ms, that of the refreshing function by 196.06 ms, and that of the switching function by 92.72 ms in the intervention group compared with the control group ( t =2.98, 4.82 ,3.21, P <0.05).@*Conclusion@#The 12 week moderate to high intensity classroom physical activity intervention has different degrees of improvement effects on cardiorespiratory fitness and executive function in Tibetan adolescents.
