Network meta-analysis of pembrolizumab as monotherapy and in combination with chemotherapy for first-line treatment of recurrent or metastatic head and neck squamous cell carcinoma / Metanálise em rede comparativa de pembrolizumabe como monoterapia e em combinação com quimioterapia para tratamento de primeira linha de carcinoma de células escamosas da cabeça e pescoço recorrente ou metastático

Pembrolizumab monotherapy or in combination with chemotherapy is approved as first-line treatment in recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC) based on improved overall survival (OS) versus EXTREME regimen in the KEYNOTE-048 trial. The clinical outcomes of pembrolizumab were compared with other recommended first-line treatments in R/M HNSCC in this study through a Bayesian network meta-analysis. A systematic literature review was conducted in July 2022, from which six trials that matched the KEYNOTE-048 patient eligibility criteria were included in the network. The OS and progression-free survival (PFS) outcomes were compared in the approved pembrolizumab indication (i.e., total population for pembrolizumab in combination with chemotherapy and combined positive score [CPS] ≥ 1 population for pembrolizumab monotherapy). A significant OS improvement was observed for pembrolizumab in combination with chemotherapy and pembrolizumab monotherapy versus EXTREME regimen (hazard ratio, 95% credible interval: 0.72, 0.60-0.86; 0.73, 0.60-0.88), platinum+5- FU (0.58, 0.43-0.76; 0.58, 0.44-0.78), and platinum+paclitaxel (0.53, 0.35-0.79; 0.53, 0.35-0.81), respectively. A non-significant numeric trend in OS improvement was observed versus the TPEx regimen. PFS was comparable with most first-line treatments and was improved versus platinum+5-FU (0.48, 0.36-0.64; 0.59, 0.45-0.79). Additional analyses in higher CPS subgroups also showed consistent results. Overall, our study results showed an improvement in OS outcomes versus alternative first-line treatments, consistent with the findings of the KEYNOTE-048 trial. These data support using pembrolizumab as a suitable firstline treatment option in R/M HNSCC.

Pembrolizumabe em monoterapia ou em combinação com quimioterapia é aprovado como tratamento de primeira linha em carcinoma de células escamosas recorrente/metastático de cabeça e pescoço (CECCP R/M) com base na melhora da sobrevida global (OS), em comparação com o esquema EXTREME no estudo KEYNOTE-048. Esse estudo comparou os resultados clínicos de pembrolizumabe com outros tratamentos recomendados de primeira linha em CECCP R/M por meio de uma metanálise de rede bayesiana. Uma revisão sistemática da literatura foi conduzida em julho de 2022, a partir da qual seis ensaios clínicos que atendiam aos critérios de elegibilidade de pacientes do KEYNOTE-048 foram incluídos na rede. Os desfechos de OS e sobrevida livre de progressão (PFS) foram comparados na indicação de pembrolizumabe (população total para pembrolizumabe em combinação com quimioterapia e população com escore positivo combinado [CPS] ≥ 1 em monoterapia com pembrolizumabe). Foi observada melhora significativa na OS para pembrolizumabe em combinação com quimioterapia e monoterapia com pembrolizumabe versus o esquema EXTREME (razão de risco, intervalo de confiança de 95%: 0,72, 0,60-0,86; 0,73, 0,60-0,88), platina+5-FU (0,58, 0,43-0,76; 0,58, 0,44-0,78) e platina+paclitaxel (0,53, 0,35-0,79; 0,53, 0,35-0,81), respectivamente. Uma tendência numérica não significativa de melhoria na OS foi observada em relação ao esquema TPEx. A PFS foi comparável com a maioria dos tratamentos de primeira linha e melhor em relação à platina+5-FU (0,48, 0,36-0,64; 0,59, 0,45-0,79). Análises adicionais em subgrupos com CPS mais elevado também mostraram resultados consistentes. No geral, os resultados de nosso estudo mostraram melhora nos desfechos de OS em comparação aos tratamentos de primeira linha alternativos, consistentes com os achados do estudo KEYNOTE-048. Esses dados apoiam o uso de pembrolizumabe como opção de tratamento em primeira linha em pacientes com CECCP R/M.

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.

Introducción: Las ciencias de la nutrición y los alimentos innovan en la industria elaborando productos con compuestos nutricionales que contribuyan a la resolución de problemáticas en salud pública. Pero, además de las características nutricionales, son importantes las características sensoriales, siendo un factor determinante en la aceptación de estos productos. Objetivo: Evaluar características fisicoquímicas, nutricionales y sensoriales de dos complementos alimenticios, tipo sopa y bebida achocolatada, desarrollados con biofortificación. Materiales y métodos: Se consideraron 3 fases, fase 1, preparación de dos tipos complementos alimenticios (4 formulaciones), usando la liofilización para la deshidratación de algunas materias primas, complementada con otras técnicas de procesamiento y cocción. Fase 2, evaluación sensorial por panel de expertos a través de prueba descriptiva cuantitativa y hedónica, y fase 3, caracterización bromatológica. El análisis de la información se realizó con el software Jamovi 2.3.21. mediante análisis descriptivo e inferencial. Resultados: El análisis sensorial evidenció que los alimentos que contiene corazón de res en un 5% fueron los más aceptados por los panelistas en todos los atributos sensoriales en ambos complementos. La caracterización bromatológica mostró que el complemento tipo bebida achocolatada con corazón es excelente fuente de proteína, zinc y calcio y buena fuente de hierro y vitamina E, mientras que, el complemento tipo sopa con corazón es excelente fuente de proteína, zinc, hierro, tiamina, omega 3, vitamina E y buena fuente de calcio de acuerdo con la normatividad colombiana de rotulado y etiquetado nutricional. Conclusiones: Ambos complementos con corazón mostraron una aceptación sensorial satisfactoria, presentaron una importante concentración de nutrientes, que, por su fuente natural y animal, son considerados de alta biodisponibilidad(AU)

Introduction: Nutrition and food sciences innovate in the industry by elaborating products with nutritional compounds that contribute to the resolution of public health problems. But, in addition to nutritional characteristics, sensory characteristics are important, being a determining factor in the acceptance of these products. Objective: To evaluate physicochemical, nutritional and sensory characteristics of two food supplements, soup and chocolate drink, developed with biofortification. Materials and methods: Three phases were considered: phase 1, preparation of two types of food supplements (4 formulations), using freeze-drying for dehydration of some raw materials, complemented with other processing and cooking techniques. Phase 2, sensory evaluation by expert panel through quantitative descriptive and hedonic test, and phase 3, bromatological characterization. The analysis of the information was carried out with Jamovi 2.3.21. software through descriptive and inferential analysis. Results: The sensory analysis showed that foods containing 5% beef heart were the most accepted by the panelists in all sensory attributes in both supplements. The bromatological characterization showed that the chocolate drink type supplement with heart is an excellent source of protein, zinc and calcium and a good source of iron and vitamin E, while the soup type supplement with heart is an excellent source of protein, zinc, iron, thiamine, omega 3, vitamin E and a good source of calcium in accordance with Colombian regulations on nutritional labeling and labeling. Conclusions: Both supplements with heart showed a satisfactory sensory acceptance, presented an important concentration of nutrients, which, due to their natural and animal source, are considered of high bioavailability(AU)

Relación entre la compatibilidad del HLA y la pérdida del injerto en trasplante renal de donante cadavérico: Un análisis por propensity score matching en Colombia / Relationship between HLA compatibility and graft loss in renal transplant from a deceased donor: An analysis by propensity score matching in Colombia

Introducción. En Colombia, solo un 24 % de los pacientes en lista recibieron un trasplante renal, la mayoría de donante cadavérico. Para la asignación de órganos se considera el HLA A-B-DR, pero la evidencia reciente sugiere que el HLA A-B no está asociado con los desenlaces del trasplante. El objetivo de este estudio fue evaluar la relevancia del HLA A-B-DR en la sobrevida del injerto de los receptores de trasplante renal. Métodos. Estudio de cohorte retrospectivo que incluyó pacientes trasplantados renales con donante cadavérico en Colombiana de Trasplantes, desde 2008 a 2023. Se aplicó un propensity score matching (PSM) para ajustar las covariables en grupos de comparación por compatibilidad y se evaluó la relación del HLA A-B-DR con la sobrevida del injerto renal por medio de la prueba de log rank y la regresión de Cox. Resultados. Se identificaron 1337 pacientes transplantados renales, de los cuales fueron mujeres un 38,7 %, con mediana de edad de 47 años y de índice de masa corporal de 23,8 kg/m2. Tras ajustar por PSM las covariables para los grupos de comparación, la compatibilidad del HLA A-B no se relacionó significativamente con la pérdida del injerto, con HR de 0,99 (IC95% 0,71-1,37) para HLA A y 0,75 (IC95% 0,55-1,02) para HLA B. Solo la compatibilidad por HLA DR fue significativa para pérdida del injerto con un HR de 0,67 (IC95% 0,46-0,98). Conclusión. Este estudio sugiere que la compatibilidad del HLA A-B no influye significativamente en la pérdida del injerto, mientras que la compatibilidad del HLA DR sí mejora la sobrevida del injerto en trasplante renal con donante cadavérico

Introduction. In Colombia, only 24% of patients on the waiting list received a renal transplant, most of them from cadaveric donors. HLA A-B-DR is considered for organ allocation, but recent evidence suggests that HLA A-B is not associated with transplant outcomes. The objective of this study was to evaluate the relevance of HLA A-B-DR on graft survival in kidney transplant recipients. Methods. Retrospective cohort study that included kidney transplant recipients with a cadaveric donor in Colombiana de Trasplantes from 2008 to 2023. A propensity score matching (PSM) was applied to adjust the covariates in comparison groups for compatibility, and the relationship of HLA A-B-DR with kidney graft survival was evaluated using the log rank test and Cox regression. Results. A total of 1337 kidney transplant patients were identified; of those, 38.7% were female, with median age of 47 years, and BMI 23.8 kg/m2. After adjusting the covariates with PSM for the comparison groups, HLA A-B matching was not significantly related to graft loss, with HR of 0.99 (95% CI 0.71-1.37) and 0.75 (95% CI 0.55-1.02), respectively. Only HLA DR matching was significant for graft loss with an HR of 0.67 (95% CI 0.46-0.98). Conclusions. This study suggests that HLA A-B matching does not significantly influence graft loss, whereas HLA DR matching does improve graft survival in renal transplantation with a cadaveric donor.

Factors associated with non-treatment of hypertension and gender differences at baseline in the ELSA-Brasil cohort

The treatment of arterial hypertension (AH) contributes to the reduction of morbidity and mortality. Gender differences are likely to play a role, as non-treatment is associated with clinical and sociodemographic aspects. The aim of this study was to investigate the factors associated with non-treatment of AH and gender differences in hypertensive individuals from the ELSA-Brasil cohort. The study was conducted with 5,743 baseline hypertensive cohort participants. AH was considered if there was a previous diagnosis or if systolic blood pressure (SBP) was ≥140 and/or diastolic BP (DBP) was ≥90 mmHg. Sociodemographic and anthropometric data, lifestyle, comorbidities, and use of antihypertensive medications were evaluated through interviews and in-person measurements. Treatment with renin-angiotensin-aldosterone system inhibitors (RAASi) or other antihypertensive medications and non-treatment were evaluated with multivariate logistic regression. Non-treatment was observed in 32.8% of hypertensive individuals. Of the 67.7% treated individuals, 41.1% received RAASi. Non-treatment was associated with alcohol consumption in women (OR=1.41; 95%CI: 1.15-1.73; P=0.001), lowest schooling level in men (OR=1.70; 95%CI: 1.32-2.19; P<0.001), and younger age groups in men and women (strongest association in males aged 35-44 years: OR=4.58, 95%CI: 3.17-6.6, P<0.001). Among those using RAASi, a higher proportion of white, older individuals, and with more comorbidities was observed. The high percentage of non-treatment, even in this civil servant population, indicated the need to improve the treatment cascade for AH. Public health policies should consider giving special attention to gender roles in groups at higher risk of non-treatment to reduce inequities related to AH in Brazil.

Ablação por Cateter para Fibrilação Atrial em Pacientes com Fração de Ejeção do Ventrículo Esquerdo ≤ 45%: Uma Metanálise de Ensaios Clínicos Randomizados / Catheter Ablation for Atrial Fibrillation in Patients with Left Ventricular Ejection Fraction ≤ 45%: A Meta-Analysis of Randomized Controlled Trials

Resumo Fundamento A fibrilação atrial (FA) e a insuficiência cardíaca (IC) coexistem frequentemente, resultando em desfechos adversos. No entanto, permanecem controvérsias quanto à eficácia da ablação por cateter (AC) em pacientes com FA com disfunção ventricular esquerda grave. Objetivos O objetivo deste estudo foi realizar uma metanálise de ensaios prospectivos randomizados e controlados para avaliar a eficácia da AC versus terapia médica (TM) em pacientes com FA com fração de ejeção do ventrículo esquerdo (FEVE) ≤45%. Métodos Procuramos na literatura estudos que comparassem AC com TM em pacientes com FA com FEVE ≤45%. Foi realizada uma metanálise de 7 ensaios clínicos, incluindo 1.163 pacientes com FA e IC. A análise de subgrupo foi realizada com base na FEVE basal. Todos os testes foram bilaterais; apenas o valor p <0,05 foi considerado estatisticamente significativo. Resultados Descobrimos que a AC estava associada a menor mortalidade por todas as causas (taxa de risco: 0,52, IC 95%: 0,37 a 0,72; p<0,01) e maiores melhorias na FEVE (diferença média: 4,80%, IC 95%: 2,29% a 7,31%; p<0,01) em comparação com TM. Os pacientes do grupo AC apresentaram menor risco de hospitalização por IC e recorrência de FA e qualidade de vida significativamente melhor do que aqueles do grupo TM. Os resultados da análise de subgrupo indicaram que pacientes com disfunção ventricular esquerda mais leve melhoraram a FEVE após a ablação de FA (diferença média: 6,53%, IC 95%: 6,18% a 6,88%; p<0,01) em comparação com pacientes com doença mais grave (diferença média : 2,02%, IC 95%: 0,87% a 3,16%; p<0,01). Conclusões Nossa metanálise demonstrou que a AC foi associada a melhorias significativas nos resultados de pacientes com FA com FEVE ≤45%. Além disso, pacientes com FA com disfunção ventricular esquerda mais leve poderiam se beneficiar mais com a AC.

Abstract Background Atrial fibrillation (AF) and heart failure (HF) frequently coexist, resulting in adverse outcomes. However, controversies remain regarding the efficacy of catheter ablation (CA) in AF patients with severe left ventricular dysfunction. Objectives The purpose of this study was to perform a meta-analysis of prospective randomized controlled trials to evaluate the efficacy of CA versus medical therapy (MT) in AF patients with left ventricular ejection fraction (LVEF) ≤45%. Methods We searched the literature for studies that compared CA to MT in AF patients with LVEF ≤45%. A meta-analysis of 7 clinical trials was performed, including 1163 patients with AF and HF. Subgroup analysis was performed based on baseline LVEF. All tests were 2-sided; only the p-value <0.05 was considered statistically significant. Results We found that CA was associated with lower all-cause mortality (risk ratio: 0.52, 95% CI: 0.37 to 0.72; p<0.01) and greater improvements in LVEF (mean difference: 4.80%, 95% CI: 2.29% to 7.31%; p<0.01) compared to MT. Patients in the CA group had a lower risk of HF hospitalization and AF recurrence and a significantly better quality of life than those in the MT group. The results of subgroup analysis indicated that patients with milder left ventricular dysfunction improved LVEF after AF ablation (mean difference: 6.53%, 95% CI: 6.18% to 6.88%; p<0.01) compared to patients with more severe disease (mean difference: 2.02%, 95% CI: 0.87% to 3.16%; p<0.01). Conclusions Our meta-analysis demonstrated that CA was associated with significant improvements in outcomes of AF patients with LVEF ≤45%. Additionally, AF patients with milder left ventricular dysfunction could benefit more from CA.

Análise dos feminicídios no estado de Pernambuco: violência de gênero e invisibilidade / Analysis of femicides in the state of Pernambuco: gender-based violence and invisibility / Análisis de los feminicidios en el estado de Pernambuco: violencia de género e invisibilidad

O feminicídio é um fenômeno decorrente da herança patriarcal machista e de estruturas sociais historicamente permeadas por relações desiguais de gênero. O objetivo desta dissertação, que é um estudo ecológico, foi analisar os aspectos epidemiológicos dos feminicídios registrados em Pernambuco, entre 2016 e 2019. Como proxy dos eventos de feminicídio, foi admitido como referência o registro de homicídios e de mortes por causas indeterminadas de mulheres no Sistema de Informações sobre Mortalidade. Foram estabelecidas etapas de buscas com o linkage probabilístico em bases de dados da saúde e, de forma complementar, de revisões manuais em plataforma do Tribunal de Justiça de Pernambuco (TJPE) e mídias noticiosas online. Realizou-se a descrição dos dados mediante a distribuição de frequências, medidas de tendência central e dispersão. Para analisar o padrão espacial das taxas de feminicídio, foram utilizados o método bayesiano empírico local e o índice de autocorrelação de Moran. Aplicou-se a regressão logística hierarquizada para verificar a associação entre o feminicídio e a violência interpessoal e estimar a razão de chances (Odds Ratio) com intervalos de confiança de 95% (IC95%). Assim, foram localizados 490 feminicídios, o que correspondeu a uma taxa de 2,5 por 100.000 mulheres. A maior proporção de feminicídios foi identificada pela busca manual em mídias noticiosas online e na base processual do TJPE (n = 247; 50,41%). As características principais das vítimas são: idade entre 20 e 39 anos (n = 286; 58,37%); raça/cor negra (n = 400; 81,63%); sem companheiro(a) (n = 407; 83,06%); e escolaridade superior a oito anos de estudo (n = 303; 61,84%). A autocorrelação espacial do evento foi confirmada pelo índice global de Moran das taxas suavizadas (I = 0,3; p = 0,001); a autocorrelação local reforça a interiorização do evento ao apontar área crítica (Q1) formada por municípios localizados na macrorregião do Vale do São Francisco e Araripe. No nível de determinação distal, identificou-se que as seguintes variáveis elevam as chances de ocorrência do feminicídio: residir em município de pequeno porte (OR = 2,10); indisponibilidade de delegacias especializadas no atendimento à mulher (OR = 1,11); e ausência de encaminhamentos para rede assistencial e protetiva na oportunidade de agressão anterior (OR = 1,32). Nos determinantes intermediários, destacou-se que, quanto maior é a intensidade do meio de ação empregado na prática da violência, maior é a chance do desfecho fatal, ressaltando-se o uso de objeto perfurocortante (OR = 3,93) e arma de fogo (OR = 11,14). E, acerca dos determinantes proximais, as vítimas inseridas na faixa etária entre 10 e 19 anos apresentaram menor chance quanto à ocorrência de feminicídio (OR = 0,51). A caracterização da população de estudo pode proporcionar a ampliação dos conhecimentos sobre violência estrutural contra as mulheres, aspectos da notificação e da rede assistencial e protetiva. A análise espacial identificou a interiorização do evento e áreas de transição em Pernambuco, as quais requerem priorização de intervenções. E a modelagem evidenciou que as mulheres estão expostas a múltiplos fatores de risco para a ocorrência de feminicídio, de forma que a discussão, de modo particularizado a todos os níveis de determinação, faz-se ainda mais necessária.

Feminicide results from the sexist patriarchal heritage and social structures historically permeated by unequal gender relations. This ecological study analyzes the epidemiological aspects of feminicides recorded in Pernambuco between 2016 and 2019. Records of homicides and undetermined causes of death of women available in the Mortality Information System were the proxy for feminicide events and accepted as reference. Search steps were established with probabilistic linkage in health databases, as well as manual reviews on the Pernambuco Court of Justice (TJPE) platform and online news media as a complement. Data were described by the distribution of frequencies, measures of central tendency and dispersion. Local empirical Bayesian method and Moran's autocorrelation index were used in the spatial pattern analysis of femicide rates. Hierarchical logistic regression was applied to verify the association between femicide and interpersonal violence and to estimate the Odds Ratio with 95% confidence intervals (95%CI). Search returned a total of 490 feminicides, corresponding to a rate of 2.5 per 100,000 women. The highest proportion of feminicides was identified by manual search in online news media and in the TJPE database (n = 247; 50.41%). Most victims were aged between 20 and 39 years (n = 286; 58.37%), black (n = 400; 81.63%), had no partner (n = 407; 83.06%) and with over eight years of schooling (n = 303; 61.84%). Spatial autocorrelation of the event was confirmed by the Global Moran Index of smoothed rates (I = 0.3; p = 0.001). Local autocorrelation reinforces the interiorization of the phenomenon by pointing to a critical area (Q1) formed by municipalities located in the Vale do São Francisco and Araripe macroregion. At the distal level, the following variables increase the chances of feminicide: living in a small city (OR = 2.10); unavailability of specialized police stations (OR = 1.11); and absence of referrals to the care and protection network in the event of a previous aggression (OR = 1.32). Regarding intermediate determinants, the greater the violence inflicted the greater the chance of a fatal outcome, emphasizing the use of sharp objects (OR = 3.93) and firearms (OR = 11.14). Regarding proximal determinants, victims in the age group 10-19 years old were less likely to be a victim of femicide (OR = 0.51). Characterizing the study population can further knowledge about structural violence against women, and aspects of the notification and the care and protection network. Spatial analysis pointed to the interiorization of the phenomenon and transition areas in Pernambuco, requiring prioritization of interventions. The modeling showed that women are exposed to multiple risk factors for feminicide and further discussions at all levels of determination are necessary.

El feminicidio es un fenómeno derivado de la herencia patriarcal machista y de estructuras sociales históricamente permeadas por relaciones desiguales de género. Este estudio de tipo ecológico tuvo por objetivo analizar los aspectos epidemiológicos de los feminicidios registrados en Pernambuco, en el período entre 2016 y 2019. Como proxy de los eventos de feminicidio, se utilizó como referencia el registro de homicidios y de causas indeterminadas de muertes de mujeres en el Sistema de Informaciones sobre Mortalidad. Se establecieron etapas de búsquedas con vinculación probabilística en las bases de datos de salud y, de forma complementaria, búsquedas manuales en la plataforma del Tribunal de Justicia de Pernambuco (TJPE) y medios en línea. Para describir los datos se utilizaron la distribución de frecuencias, medidas de tendencia central y dispersión. Para analizar el padrón espacial de las tasas de feminicidio se emplearon el método bayesiano empírico local y el índice de autocorrelación de Moran. Se aplicó la regresión logística jerarquizada para constatar la asociación entre el feminicidio y la violencia interpersonal, y estimar la razón de posibilidades (Odds Ratio) con intervalos de confianza del 95% (IC95%). Los resultados apuntaron a 490 feminicidios, lo que correspondió a una tasa de 2,5 por 100.000 mujeres. La mayor proporción de feminicidios se identificó mediante la búsqueda manual en prensa en línea y en la base procesal del TJPE (n = 247; 50,41%). Las principales características de las víctimas fueron edad entre 20 y 39 años (n = 286; 58,37%), raza/color negro (n = 400; 81,63%), sin compañero(a) (n = 407; 83,06%) y nivel de estudios superior a ocho años de estudio (n = 303; 61,84%). La autocorrelación espacial del evento se confirmó mediante el índice de Moran global de las tasas suavizadas (I = 0,3, p = 0,001); la autocorrelación local refuerza la interiorización del evento al señalar área crítica (Q1) formada por municipios situados en la macrorregión del Valle de São Francisco y Araripe. En el nivel de determinación distal se identificó que las siguientes variables aumentan las posibilidades de feminicidio: residir en municipio de pequeño tamaño, (OR = 2,10); indisponibilidad de comisarías especializadas en la atención a la mujer (OR = 1,1); y ausencia de remisiones a la red asistencial y protectora en la ocasión de agresión anterior (OR = 1,32). En los determinantes intermediarios, se destacó que cuanto mayor es la intensidad del medio de acción empleado en la práctica de la violencia, mayor es la posibilidad de desenlace fatal, destacándose el empleo de objeto cortopunzante (OR = 3,93) y arma de fuego (OR = 11,14). En cuanto a los determinantes proximales, las víctimas comprendidas en el tramo de edad comprendido entre los 10 y los 19 años presentaron menos posibilidad de incidencia de feminicidio (OR = 0,51). La caracterización de la población de estudio puede proporcionar la ampliación de los conocimientos sobre violencia estructural contra la mujer, aspectos de la notificación y de la red asistencial protectora. El análisis espacial identificó la interiorización del evento y áreas de transición en Pernambuco, las cuales requieren priorización de las intervenciones. Y el modelaje reveló que las mujeres están expuestas a múltiples factores de riesgo para la incidencia de feminicidio y el debate, de modo particularizado de todos los niveles de determinación, se hace todavía más necesario.

Establishment of a Predictive Model for Chronic Cough after Pulmonary Resection / 中国肺癌杂志

BACKGROUND@#Chronic cough after pulmonary resection is one of the most common complications, which seriously affects the quality of life of patients after surgery. Therefore, the aim of this study is to explore the risk factors of chronic cough after pulmonary resection and construct a prediction model.@*METHODS@#The clinical data and postoperative cough of 499 patients who underwent pneumonectomy or pulmonary resection in The First Affiliated Hospital of University of Science and Technology of China from January 2021 to June 2023 were retrospectively analyzed. The patients were randomly divided into training set (n=348) and validation set (n=151) according to the principle of 7:3 randomization. According to whether the patients in the training set had chronic cough after surgery, they were divided into cough group and non-cough group. The Mandarin Chinese version of Leicester cough questionnare (LCQ-MC) was used to assess the severity of cough and its impact on patients' quality of life before and after surgery. The visual analog scale (VAS) and the self-designed numerical rating scale (NRS) were used to evaluate the postoperative chronic cough. Univariate and multivariate Logistic regression analysis were used to analyze the independent risk factors and construct a model. Receiver operator characteristic (ROC) curve was used to evaluate the discrimination of the model, and calibration curve was used to evaluate the consistency of the model. The clinical application value of the model was evaluated by decision curve analysis (DCA).@*RESULTS@#Multivariate Logistic analysis screened out that preoperative forced expiratory volume in the first second/forced vital capacity (FEV1/FVC), surgical procedure, upper mediastinal lymph node dissection, subcarinal lymph node dissection, and postoperative closed thoracic drainage time were independent risk factors for postoperative chronic cough. Based on the results of multivariate analysis, a Nomogram prediction model was constructed. The area under the ROC curve was 0.954 (95%CI: 0.930-0.978), and the cut-off value corresponding to the maximum Youden index was 0.171, with a sensitivity of 94.7% and a specificity of 86.6%. With a Bootstrap sample of 1000 times, the predicted risk of chronic cough after pulmonary resection by the calibration curve was highly consistent with the actual risk. DCA showed that when the preprobability of the prediction model probability was between 0.1 and 0.9, patients showed a positive net benefit.@*CONCLUSIONS@#Chronic cough after pulmonary resection seriously affects the quality of life of patients. The visual presentation form of the Nomogram is helpful to accurately predict chronic cough after pulmonary resection and provide support for clinical decision-making.

Mutational Signatures Analysis of Micropapillary Components and Exploration of ZNF469 Gene in Early-stage Lung Adenocarcinoma with Ground-glass Opacities / 中国肺癌杂志

BACKGROUND@#In China, lung cancer remains the cancer with the highest incidence and mortality rate. Among early-stage lung adenocarcinomas (LUAD), the micropapillary (MPP) component is prevalent and typically exhibits high aggressiveness, significantly correlating with early metastasis, lymphatic infiltration, and reduced five-year survival rates. Therefore, the study is to explore the similarities and differences between MPP and non-micropapillary (non-MPP) components in malignant pulmonary nodules characterized by GGOs in early-stage LUAD, identify unique mutational features of the MPP component and analyze the relationship between the ZNF469 gene, a member of the zinc-finger protein family, and the prognosis of early-stage LUAD, as well as its correlation with immune infiltration.@*METHODS@#A total of 31 malignant pulmonary nodules of LUAD were collected and dissected into paired MPP and non-MPP components using microdissection. Whole-exome sequencing (WES) was performed on the components of early-stage malignant pulmonary nodules. Mutational signatures analysis was conducted using R packages such as maftools, Nonnegative Matrix Factorization (NMF), and Sigminer to unveil the genomic mutational characteristics unique to MPP components in invasive LUAD compared to other tumor tissues. Furthermore, we explored the expression of the ZNF469 gene in LUAD using The Cancer Genome Atlas (TCGA) database to investigate its potential association with the prognosis. We also investigated gene interaction networks and signaling pathways related to ZNF469 in LUAD using the GeneMANIA database and conducted Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Lastly, we analyzed the correlation between ZNF469 gene expression and levels of immune cell infiltration in LUAD using the TIMER and TISIDB databases.@*RESULTS@#MPP components exhibited a higher number of genomic variations, particularly the 13th COSMIC (Catalogue of Somatic Mutations in Cancer) mutational signature characterized by the activity of the cytidine deaminase APOBEC family, which was unique to MPP components compared to non-MPP components in tumor tissues. This suggests the potential involvement of APOBEC in the progression of MPP components in early-stage LUAD. Additionally, MPP samples with high similarity to APOBEC signature displayed a higher tumor mutational burden (TMB), indicating that these patients may be more likely to benefit from immunotherapy. The expression of ZNF469 was significantly upregulated in LUAD compared to normal tissue, and was associated with poor prognosis in LUAD patients (P<0.05). Gene interaction network analysis and GO/KEGG enrichment analysis revealed that COL6A1, COL1A1, COL1A2, TGFB2, MMP2, COL8A2 and C2CD4C interacted with ZNF469 and were mainly involved in encoding collagen proteins and participating in the constitution of extracellular matrix. ZNF469 expression was positively correlated with immune cell infiltration in LUAD (P<0.05).@*CONCLUSIONS@#The study has unveiled distinctive mutational signatures in the MPP components of early-stage invasive LUAD in the Asian population. Furthermore, we have identified that the elevated expression of mutated ZNF469 impacts the prognosis and immune infiltration in LUAD, suggesting its potential as a diagnostic and prognostic biomarker in LUAD.

A total of 15 batches of samples were clustered into 3 groups， with S1-S6， S7-S10， and S11-S15 clustered into one group， respectively. The VIP values of protodioscin， epicatechin， dioscin and 6-gingerol were greater than 1. Euclidean closeness values of the optimal solution （C）i for 15 batches of samples were 0.163 5 to 0.703 7， and Ci values of S11-S15 were all higher than 0.6. CONCLUSIONS The established QAMS method is accurate and simple， and can be used for comprehensive quality evaluation of Guge fengtong tablets， by combining with chemometric analysis and EW-TOPSIS method. Protodioscin， epicatechin， dioscin and 6-gingerol are the differential markers that affect the quality of Guge fengtong tablets. Samples S11-S15 have better quality.

Insights from Japan’s cost-effectiveness analysis policy on pricing for China’s NRDL access / 中国药房

The cost-effectiveness analysis policy for drugs was institutionalized in Japan since 2019， realizing quantitative adjustment of price across varieties. A hierarchical categorization approach was adopted to select medicines with high expected annual sales. For selected medicines， adjustments were made to the premium and profit components within the existing price structure based on a pre-defined incremental cost-effectiveness ratio （ICER） threshold， effectively resolving the issue of inconsistent criteria and magnitudes caused by subjective judgment. Meanwhile， incentive measures like evaluation exemption or threshold enhancement were granted for specific medicines. Besides， a price adjustment mechanism， which was allowed for upward and downward adjustments， involving tiered ICER threshold and quantified formulas， had been established for the premium and profit components of drug price. In China’s National Reimbursement Drug List （NRDL） access， certain issues remained to be addressed： insufficient clarity in the quantitative mechanism of price formation， incomplete price adjustment measures， and lagging in the communication channels. It is recommended that the following measures could be referred to when further improving the scientificity and fairness of drug pricing during China’s NRDL access， such as enhancing the ICER threshold for medicines catering to special populations， quantifying criteria and extents for price adjustment， granting preferential pricing policies to pharmaceutical companies that present high-quality evidence of effectiveness， preceding communication channels with pharmaceutical companies， as well as exploring a price floor mechanism for the drugs with excessive price reduction.

Cloning and gene functional analysis study of dynamin-related protein GeDRP1E gene in Gastrodia elata / 药学学报

The gene GeDRP1E encoding dynamin-related protein 1E in Gastrodia elata was cloned by specific primers which were designed based on the transcriptome data of G. elata. Bioinformatics analysis on GeDRP1E gene was carried out by using ExPASy, ClustalW, MEGA, etc. Positive transgenic Arabidopsis plant and potato minituber were obtained with the genetic transformation system of Arabidopsis and potato. The plant height and seed setting rate of transgenic Arabidopsis, and agronomic characters, such as size, weight and starch content of potato minituber of transgenic potato were tested and analyzed. And GeDRP1E gene function was preliminarily investigated. The results showed that the open reading frame of GeDRP1E gene was 1 899 bp in length and 632 amino acids residues were encoded, with a relative molecular weight of 69.90 kDa and a molecular formula of C3079H4973N883O933S19. It was predicted that the theoretical isoelectric point was 7.27, the instability coefficient was 43.34, and the average hydrophilicity index was -0.259, which was indicative of an unstable hydrophilic protein. GeDRP1E has no transmembrane structure and signal peptide, and was localized in the cytoplasm. The phylogenetic tree showed that GeDRP1E was highly homologous with DRP1E proteins of other plant species, among which GeDRP1E had the highest homology with DcDRP1E (XP_020689662.1) in Dendrobium candidum, reaching 90.05%. GeDRP1E plant expression vector pCambia1300-35Spro-GeDRP1E was constructed by double digests, and Arabidopsis complementary mutant and potato overexpression strain of GeDRP1E gene were obtained by Agrobacterium-mediated gene transformation. Compared with the Arabidopsis AtDRP1E mutant, the height and seed setting rate of the GeDRP1E complementation mutant were rescued. The minituber of GeDRP1E overexpression potato had larger size, heavier weight and higher starch content, comparing to wild-type potato. It was preliminarily induced that GeDRP1E was involved in mitochondrial morphology regulation, which related to the growth and development of Arabidopsis plants and potato miniature. The research results laid a foundation for further elucidating the molecular mechanisms underlying the growth and development of G. elata tuber development.

AIM: To explore the correlation between neonatal retinal hemorrhage(RH)and changes in umbilical artery blood gas analysis.METHODS: A total of 312 full-term neonates born in our obstetrics department from January 2019 to December 2021 were selected as the study subjects. According to the RetCam III fundus examination results, 245 neonates who did not experience RH were included in the control group, while 67 cases with RH were found to be included in the RH group. In addition, neonates were grouped into I degree group(n=20), II degree group(n=29), and III degree group(n=18)based on the degree of RH. General clinical data and umbilical artery blood gas analysis indicators between the RH group and the control group were compared; the levels of umbilical artery blood gas analysis indicators in neonates with different degrees of RH, the relationship between pH and RH degree, and the influencing factors of neonatal RH were analyzed.RESULTS: There was no obvious difference in maternal age, average gestational week, fetal gender, parity, gestational diabetes, fetal birth weight, and amniotic fluid between the RH group and the control group(all P&#x003E;0.05), while there were obvious differences in delivery methods, gestational hypertension, forceps assisted delivery, neonatal asphyxia, and umbilical cord around the neck(all P&#x003C;0.05). The pH value, arterial blood sample partial pressure(PaO2)and base excess(BE)values of the RH group were obviously lower than those of the control group(all P&#x003C;0.01), while the arterial carbon dioxide partial pressure(PaCO2)was obviously higher than that of the control group(P&#x003C;0.01). There were obvious differences in umbilical artery blood gas analysis indicators among children with different degrees of RH(P&#x003C;0.05), and with the increase of the degree of RH, pH value, PaO2 and BE gradually decreased(P&#x003C;0.05), and PaCO2 gradually increased(P&#x003C;0.05). There was a negative correlation between the degree of RH and the pH of umbilical artery blood gas analysis(rs=-0.593, P&#x003C;0.05). The results of multivariate Logistic regression analysis showed that delivery method, gestational hypertension, forceps assisted delivery, neonatal asphyxia, umbilical cord entanglement, pH, PaO2, PaCO2, and BE were all influencing factors for the occurrence of neonatal RH.CONCLUSION: There is a close correlation between neonatal RH and changes in umbilical artery blood gas analysis, and umbilical artery blood gas analysis can be used for the diagnosis of neonatal RH, which can be used to guide clinical treatment.

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.
