Clinical characteristics of acute acquired concomitant esotropia among different age groups / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the clinical characteristics of acute acquired concomitant esotropia(AACE)in patients among different age groups.METHODS: Retrospective analysis of clinical data. A total of 112 non-Swan type AACE patients who underwent surgery at Peking University People's Hospital from January 2015 to December 2022 were retrospectively analyzed. Clinical data were collected and the characteristics were compared, including gender, age, diopter, duration of disease, daily time spent on near work, angles of deviation before and after surgery, stereopsis, etc. According to age, patients were divided into three groups: <18 years old group(22 cases), 18-45 years old group(67 cases), and >45 years old group(23 cases). The clinical characteristics of patients were compared in each group.RESULTS: A total of 112 patients were included in the study, comprising 56 males and 56 females, with a median age of 29.50(19.25, 41.75)years old. Among them, 97 patients had myopia(86.6%). There were 93 patients(83.0%)who spent more than 8 h on near work. The age group <18 years old had the shortest duration before surgery, with a median time of 1.00(0.50, 1.00)a, the minimum negative diopter, with a median diopter of -0.75(-3.19, -0.56)D in the right eye and the diopter of -1.25(-2.81, -0.75)D in the left eye, and the maximum preoperative near angle of deviation, with a median angle of 30.00(18.50, 80.00)PD, and the maximum preoperative distant angle of deviation, with a median angle of 35.00(23.75, 80.00)PD. All these differences were statistically significant compared with other two groups(both P<0.05). For the age group from 18 to 45 years old, the median near angle of deviation was 20.00(14.00, 30.00)PD, and the median distant angle of deviation was 25.00(20.00, 35.00)PD, both of which were higher than those in the age group >45 years old(both P<0.05). For the age group >45 years old, the median near angle of deviation after surgery was -4.50(-7.50, 0)PD, and the median distant angle of deviation after surgery was 4.50(0, 9.50)PD, which were smaller than those in other two groups(all P<0.05). The age group >45 years old had the hiughest surgical success rate(100%). The preoperative stereopsis was better in age group >45 years old than the group <18 years old(P<0.05). The postoperative stereopsis of the age group of 18 to 45 years old and the age group >45 years old was better than age group <18 years old(both P<0.05).CONCLUSION: Surgical patients with AACE are mainly in the age group from 18 to 45 years old. The characteristic of angle of deviation is that distant angle of deviation is greater than near angle of deviation. The patients <18 years old have larger preoperative angles of deviation than adults, while their stereoacuity is worse than adults in the early postoperative period. It is recommended that augmented-dose surgery should be performed in AACE patients who are in the age group of 18 to 45 years old(5-10 PD). A conservative surgery should be designed for hyperopia young children without established binocular vision.

Application of robot-assisted lung basal segmentectomy: A retrospective study / 中国胸心血管外科临床杂志

@#Objective    To summarize the experience of robot-assisted lung basal segmentectomy, and analyze the clinical application value of intersegmental tunneling and pulmonary ligament approach for S9 and/or S10 segmentectomy. Methods    The clinical data of 78 patients who underwent robotic lung basal segmentectomy in our hospital between January 2020 to May 2022 were retrospectively reviewed. There were 32 males and 46 females with a median age of 50 (33-72) years. The patients who underwent S9 and/or S10 segmentectomy were divided into a single-direction group (pulmonary ligament approach, n=19) and a bi-direction group (intersegmental tunneling, n=19) according to different approaches, and the perioperative outcomes between the two groups were compared. Results    All patients successfully completed the operation, without conversion to thoracotomy and lobectomy, serious complications, or perioperative death. The median operation time was 100 (40-185) min, the blood loss was 50 (10-210) mL, and the median number of dissected lymph nodes was 3 (1-14). There were 4 (5.1%) patients with postoperative air leakage, and 4 (5.1%) patients with hydropneumothorax. No patient showed localized atelectasis or lung congestion at 6 months after the operation. Further analysis showed that there was no significant difference in the operation time, blood loss, thoracic drainage time, complications or postoperative hospital stay between the single-direction and bi-direction groups (P>0.05). However, the number of dissected lymph nodes of the bi-direction group was more than that of the single-direction group [6 (1-13) vs. 5 (1-9), P=0.040]. Conclusion    The robotic lung basal segmentectomy for pulmonary nodules is safe and effective. The  perioperative results of robotic S9 and/or S10 complex segmentectomy using intersegmental tunneling and pulmonary ligament approach are similar.

Efeito dos padrões alimentares no tratamento e prevenção da hipertensão arterial: uma atualização / Effect of dietary patterns on the treatment and prevention of high blood pressure: an update

A hipertensão arterial (HA) é uma condição clínica caracterizada por elevação sustentada dos níveis pressóricos maior ou igual a 140 e/ou 90 mmHg. As diretrizes atuais têm apontado cada vez mais estudos que verificam a influência dos diferentes padrões alimentares e seus efeitos benéficos no controle da HA, como: Dietary Approach to Stop Hypertension (DASH) que preconiza o consumo de frutas, hortaliças, fibras, minerais e laticínios com baixos teores de gordura; DASH-Sodium a qual combina três níveis diferentes de ingestão de sódio; Dieta Mediterrânea (MedDiet) caracterizada pela ingestão reduzida de carne vermelha e processada, ovos, doces e bebidas açucaradas, somada ao consumo moderado de peixes, vinho tinto e laticínios com baixo teor de gordura e alta ingestão de azeite de oliva; Plant based cujo escopo é consumir principalmente proteínas de origem vegetal, com um padrão alimentar rico em fibras, que inclua cereais integrais, frutas, legumes, leguminosas e nozes, com uma ingestão regular de peixes e frutos do mar, laticínios com baixo teor de gordura. Todas essas intervenções mostraram benefícios nos níveis pressóricos, porém a DASH é o padrão alimentar mais frequentemente recomendado e com maior nível de evidência para a prevenção primária e o controle da HA (AU).

Arterial hypertension (AH) is a clinical condition characterized by a sustained increase in blood pressure levels higher than or equal to 140 and or 90 mmHg. Present guidelines have increasingly pointed to studies that show the influence of different dietary patterns and their beneficial effects on the control of AH, just as: Dietary Approach to Stop Hypertension (DASH), which advocates the consumption of fruits, vegetables, fiber, minerals and dairy products low in fat; DASH-Sodium which associate three different levels of sodium intake; Mediterranean Diet (MedDiet) characterized by reduced intake of red and processed meat, eggs, sweets, and sugary drinks, besides, moderate consumption of fish, red wine and low-fat dairy products and high intake of olive oil; Plant-based whose scope is to consume mainly plant-based proteins, with a dietary pattern rich in fiber, which includes whole grains, fruits, vegetables, legumes, and nuts, with a regular intake of fish and seafood, low-fat dairy products. All these interventions showed benefits in blood pressure levels, however DASH is the most frequently recommended dietary pattern with the highest level of evidence for primary prevention and AH control (AU).

Bioinformatics-based design of a fusion vaccine with CTLA-4 variable region to combat Brucella

Brucellosis has become a global zoonotic disease, seriously endangering the health of people all over the world. Vaccination is an effective strategy for protection against Brucella infection in livestock in developed countries. However, current vaccines are pathogenic to humans and pregnant animals, which limits their use. Therefore, it is very important to improve the safety and immune protection of Brucella vaccine. In this study, different bioinformatics approaches were carried out to predict the physicochemical properties, T/B epitope, and tertiary structure of Omp2b and Omp31. Then, these two proteins were sequentially linked, and the Cytotoxic T lymphocyte associated antigen-4 (CTLA-4) variable region was fused to the N-terminal of the epitope sequence. In addition, molecular docking was performed to show that the structure of the fusion protein vaccine had strong affinity with B7 (B7-1, B7-2). This study showed that the designed vaccine containing CTLA-4 had high potency against Brucella, which could provide a reference for the future development of efficient brucellosis vaccines.

A comparison between Different Surgical Approaches of Nasopharyngeal Angiofibroma: A Cross-Sectional Observational Study in BSMMU, Bangladesh

Background: The Otolaryngologist is currently dealing with a dramatic problem the nasopharyngeal angiofibroma. The posterolateral wall of the nasal cavity, close to the superior margin of the sphenopalatine foramen, is where the tumor commonly first appeared.Material & Methods:The Otolaryngology & Head Neck Surgery department at Bangabandhu Shiekh Mujib Medical University, Dhaka Medical College Hospital, and Shaheed Suhrawardy Medical College Hospital in Dhaka undertook this retrospective cross-sectional study. The research was done from February 2012 to November 2012. The study’s overall sample size was 30.Results:The majority of individuals (54%) who have nasopharyngeal angiofibroma are between the ages of 16 and 20. the majority of patients have similar symptoms such epistaxis, nasal blockage, nasal discharge, anemia, and masses in the nasal cavity. At presentation, anaemia is present to various degrees in 90% of cases. The lateral rhinotomy method is employed (40%) more often than other approaches. Three blood units were to be transfused into a maximum of 36.66% of the patients throughout the surgery.Conclusion:Nasopharyngeal angiofibroma is currently a difficult issue for otolaryngologists. When endoscopy was used instead of open techniques, we discovered that the mean length of the procedure was shorter, which may be related to endoscopy’s decreased morbidity.

Bite Marks: Indispensable Forensic Evidence

Introduction: Forensic odontology involves the collection, management, interpretation, evaluation, and presentation of dental evidence for criminal or civil legal proceedings, a combination of various aspects of the dental, scientific and legal professions. Bite mark analysis is an essential aspect of it that can significantly impact the courtroom or when considering the care of children and women deemed at risk. Materials and Methods: Data were obtained and analyzed from previously published literature and electronic database searches of relevant published literature from PubMed and Google Scholar. Forensic odontologists examine, interpret, analyze, and prepare reports on bruises or marks thought to be caused by teeth and, on occasion, are cross-examined in a court of law. Hence, they are considered essential in forensic dentistry in solving crimes to find either suspects or even victims in self-inflicted injuries as they are caused either by humans or animals that reveal biting edges, spacing, restorations, missing teeth, broken teeth, or supernumerary teeth unique to that individual. The main reasons for causation are sexual crimes, homicides, child abuse, and violent fights. There are many methods to analyze, that are classified into manual, semi-automatic, and automatic methods. Objectives: This review highlights the bite marks in detail about their characteristics, methods of collection and different methods of analysis and its applications in forensic odontology. Conclusion: This review shows different methods of analyzing bitemarks and explains the advantages, disadvantages, and limitations, and identifies which method is better advisable and adaptableforanalysis.

Revisión sobre los estudios en el campo académico de la discapacidad y las personas con discapacidad / Review on Studies in the Academic Field of Disability and Persons with Disabilities

Resumen El propósito de este trabajo es presentar un estado del arte sobre los estudios en el campo académico de la discapacidad en un intento por aportar elementos teóricos a quienes vienen trabajando la discapacidad como problema social y no como un asunto de tipo médico y rehabilitador. Se realizó una revisión documental de artículos de investigación, capítulos de libros y libros en diversas bases de datos donde se analizaron 55 fuentes documentales utilizando como técnica el análisis documental a partir del instrumento de la regilla documental. Entre los resultados se destaca que los problemas sobre los que ha girado el estudio de la discapacidad han sido en educación inclusiva, desarrollo humano, justicia social, estudios decoloniales y críticos de la discapacidad, y alrededor de la identidad y el reconocimiento. Se concluye que aún prevalece una mirada a la discapacidad y las personas con discapacidad desde la deficiencia, la superación, la rehabilitación y la limitación, y aunque existen estudios que interpelan a los sujetos con discapacidad, en estos prevalecen los abordajes alrededor de los obstáculos o elementos facilitadores para la inclusión.

Abstract This paper aims to present the state of art on research in the academic field of disability in an attempt to provide theoretical elements to those who have been working on disability as a social problem and not as a medical and rehabilitative issue. A documentary review of research articles, book chapters, and books in various databases was carried out. Fifty-five documentary sources were analyzed using the documentary analysis technique based on the documentary grid instrument. Among the results, it is highlighted that the study of disability has revolved around the aspects of inclusive education, human development, social justice, decolonial and critical studies of disability, and identity and recognition. It is concluded that disability and persons with disabilities are still viewed from the point of view of impairment, overcoming, rehabilitation, and limitation, and although there are studies that question subjects with disabilities, these studies focus on the obstacles or facilitating elements for inclusion.

Occurrence of citrus brown and black spot diseases and their control using pre-harvest approaches

Mild brown and black spot diseases symptoms were detected on citrus varieties, Valencia and Navel fruits during season 2018 in some citrus orchards at North Egypt. Collected diseased fruit samples revealed isolation of Alternaria alternata and Phyllosticta citricarpa (McAlpine) van der Aa. Some organic acids, salts and Saccharomyces cerevisiae were evaluated against the diseases incidents in vitro and in vivo. Complete growth inhibition was recorded for fungi tested at 2g/L of salicylic acid, Potassium dihydrogen phosphate, Tri-Sodium polyphosphate and 2.5 g/L of S. cerevisiae. All pre-harvest treated Valencia trees, inoculated fruits revealed no diseases symptoms up to 10 days of storage period. Meanwhile, S. cerevisiae and salicylic acid treatments had extended protective effect up to 20 days. Control strategy through spraying Valencia orange trees with yeast or some organic acids and salts as pre-harvest approaches should be taken in consideration especially these diseases began to occur in North region of Egypt.

Observation indicators: (1) clinicopathological characteristics of Siewert Ⅱ and Ⅲ AEG; (2) follow-up and survival; (3) prognostic factors analysis. Patients were followed up by telephone interview and outpatient examination to detect postoperative survival up to December 2018. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Kaplan-Meier method was used to draw survival curves and calculate survival rates. Log-rank test was used for survival analysis. Univariate and multivariate analyses were done using the COX proportional hazard model. Results:(1) Clinicopathological characteristics of Siewert Ⅱ and Ⅲ AEG. Of 399 patients, 198 cases were Siewert Ⅱ AEG and 201 cases were Siewert Ⅲ AEG. There were 130 cases undergoing transthoracic radical AEG surgery, 172 cases undergoing trans-abdominal proximal gastrectomy and 97 cases undergoing transabdominal total gastrectomy. The age, tumor diameter, cases with surgical method as transthoracic radical AEG surgery, transabdo-minal proximal gastrectomy and transabdominal total gastrectomy, the number of positive lymph nodes, cases in tumor TNM stage Ⅰ, Ⅱ, Ⅲ, Ⅳ were (65±10)years, (5.1±2.4)cm, 102, 68, 28, 17(range, 12?22), 20, 57, 117, 4 for patients with Siewert Ⅱ AEG, versus (62±12)years, (6.3±3.2)cm, 28, 104, 69,18(range, 14?27), 16, 41, 134, 10 for patients with Siewert Ⅲ AEG, showing significant differ-ences betweeen them ( t=2.83, ?3.82, χ2=66.97, U=17 407.05, 17 532.00, P<0.05). (2) Follow-up and survival. All 399 patients were followed up for 34(range, 2?160)months. The 5-year overall survival rate was 29.3% for patients with Siewert Ⅱ AEG, versus 37.0% for patients with Siewert Ⅲ AEG, showing no significant difference betweeen them ( χ2=1.46, P>0.05). The median survival time and 5-year overall survival rate were 29.0 months [95% confidence interval ( CI) as 23.4?34.6 months] and 22.9% for patients undergoing transthoracic radical AEG surgery, 43.0 months(95% CI as 33.9?52.1 months) and 34.7% for patients undergoing transabdominal proximal gastrectomy, 54.0 months (95% CI as 37.6?70.4 months)and 44.3% for patients undergoing transabdominal total gastrectomy, showing a significant difference in the survival among the 3 groups ( χ2=13.81, P<0.05). Of the 198 Siewert Ⅱ AEG patients, the 5-year overall survival rate was 24.6% for the 96 patients undergoing transabdominal surgery, versus 35.4% for the 102 patients undergoing transthoracic surgery, showing no significant difference in the survival between them ( χ2=3.10, P>0.05). Of the 201 Siewert Ⅲ AEG patients, the 5-year overall survival rate was 40.0% for the 173 patients undergoing transabdominal surgery, versus 16.1% for the 28 patients undergoing transthoracic surgery, showing a significant difference between them ( χ2=11.32, P<0.05). (3) Prognostic factors analysis. Results of univariate analysis showed that surgical method, pathological N staging, patholgical M staging were related factors for prognosis of Siewert Ⅱ and Ⅲ AEG ( hazard ratio=0.68, 1.25, 2.18, 95% CI as 0.54?0.86, 1.15?1.36, 1.28?3.73, P<0.05). Results of multivariate analysis showed that transthoracic approach, pathological stage N2?N3 and pathological stage M1 were independent risk factors for prognosis of Siewert Ⅱ and Ⅲ AEG ( hazard ratio=0.64, 1.25, 2.18, 95% CI as 0.51?0.80, 1.16?1.35, 1.28?3.70, P<0.05). Conclusions:Compared with Siewert Ⅲ AEG, Siewert Ⅱ AEG has a smaller tumor diameter, less positive lymph nodes, poorer prognosis. Transthoracic approach is preffered for the Siewert Ⅱ AEG. Transthoracic approach, pathological stage N2?N3 and pathological stage M1 are independent risk factors for prognosis of Siewert Ⅱ and Ⅲ AEG.

Correlation between dietary approaches to stop hypertension pattern and central obesity affected by PM2.5 exposure / 环境与职业医学

Background There is a lack of evidence on whether exposure to PM2.5 and its constituents would affect the relationship between the dietary approaches to stop hypertension (DASH) and central obesity. Objective To investigate the effect of exposure to PM2.5 and its constituents on the correlation between the DASH dietary pattern and the prevalence of central obesity. Methods The data were obtained from the baseline survey of the "Xinjiang Multi-Ethnic Natural Population Cohort Construction and Health Follow-Up Study" in Urumqi. A DASH score was calculated according to intake frequency of 8 food groups, and summed from intake frequency of recommended food groups scored from 1 to 5 from low to high, and intake frequency of restricted food groups scored from 1 to 5 from high to low. A higher DASH score indicates better compliance with the DASH dietary pattern. We estimated exposure using satellite-derived PM2.5 and a chemical transport model (GEOS-Chem) for its constituents, including organic carbon (OC), black carbon (BC), sulfate (SO42−), nitrate (NO3−), ammonium (NH4+), and soil dust. Central obesity was defined by waist circumference: ≥90 cm for men or ≥85 cm for women according to Criteria of weight for adults (WS/T 428—2013). A logistic regression model was used to analyze the effects of the DASH dietary pattern as well as PM2.5 and its constituents on central obesity, and a stratified analysis was used to explore the effects of PM2.5 and its constituents on the association between the DASH dietary pattern and central obesity. Results The study included 9 565 urban residents, aged (62.30±9.42) years, with a central obesity prevalence rate of 60.75%. After adjusting for selected confounders, the DASH score Q5 group had a 17.5% lower risk of central obesity than the Q1 group (OR=0.825, 95%CI: 0.720-0.947). PM2.5 and its constituents OC, BC, SO42−, NH4+, and soil dust were positively associated with the prevalence of central obesity, but no association was observed between constituent NO3− exposure and central obesity. The stratified analysis revealed that the prevalence of central obesity was reduced in the DASH score Q5 group in participants exposed to low concentrations of PM2.5 and its constituents NO3−, NH4+, and soil dust, while the protective effect of the DASH pattern on central obesity disappeared in subjects exposed to high concentrations of PM2.5 and its constituents NO3−, NH4+, and soil dust. Conclusion Exposure to PM2.5 and its constituents NO3−, NH4+, and soil dust could attenuate the protective effect of the DASH pattern on central obesity.

Efeitos do sal de ervas sobre a pressão arterial e a excreção de sódio urinário de pessoas com hipertensão / Effects of herbal salt on blood pressure and urinary sodium excretion in people with hypertension

A presente pesquisa teve por objetivo analisar os efeitos da substituição do sal de cozinha por sal de ervas sobre os valores de pressão arterial e excreção de sódio urinário de pessoas com hipertensão arterial. Trata-se de um estudo de abordagem quantitativa e delineamento quasi-experimental, tipo "cross-over", com amostra de hipertensos cadastrados em três unidades públicas de saúde de um município do estado de Mato Grosso. A coleta de dados foi realizada no período de maio de 2020 a maio de 2022. Por meio de entrevista, foi aplicado o questionário para identificação das variáveis sociodemográficas e o "Questionário de Adesão a Medicamentos - Qualiaids" (QAM-Q). Posteriormente, foi realizada a avaliação antropométrica e a medida casual da pressão arterial. A pesquisa foi dividida em três etapas: Etapa 1 - os participantes permaneceram em uso habitual do sal de cozinha, durante sete dias; Etapa 2 - os participantes fizeram uso exclusivo de cinco gramas de sal por dia, durante 10 dias; Etapa 3 - os participantes usaram exclusivamente o sal de ervas para o preparo das refeições, durante 10 dias. Em todas as etapas, foi realizada a Monitorização Residencial da Pressão Arterial (MRPA) e a dosagem de sódio urinário. As análises descritivas foram realizadas por meio do pacote estatístico IBM Statistical Package for Social Science - SPSS®, versão 25.0. O teste ANOVA foi utilizado para comparações entre as médias pareadas. Os resultados foram expressos como valores médios, desvio padrão (dp), mínimo, máximo e mediana. Para diferença estatística foi considerado p<0,05. Participaram do estudo 24 indivíduos, com idade média de 63,2 ± 10 anos, a maioria mulheres (54,2%), que convivem com companheiro (70,8%), de cor da pele autodeclarada branca (54,2%), com média de 7,6 anos de estudo e aposentados (45,8%). Em relação às variáveis clínicas, houve predomínio de participantes com pressão arterial ótima (45,8%), na categoria sobrepeso (45,8%), com risco cardiovascular elevado segundo relação cintura-estatura (87,5%) e risco muito elevado de acordo com a medida da circunferência da cintura (54,1%); 62,5% se mostraram aderentes ao tratamento. Na comparação entre as três etapas, observou-se redução significante nos valores de Pressão Arterial Sistólica (p=0,003) e Pressão Arterial Diastólica (p=0,001), sem diferença nas variáveis consumo de sal (p=0,66) e excreção de sódio urinário (p=0,66). Ainda que o uso do sal de ervas seja uma estratégia não medicamentosa interessante e inovadora para o controle da pressão arterial, os participantes não aderiram de forma expressiva à intervenção proposta. De qualquer forma, salienta-se que a monitorização do consumo de sódio é primordial para a avaliação do uso do sal pela população, tendo em vista a implementação de medidas visando a redução da pressão arterial e a prevenção de eventos cardiovasculares

The present research aimed to analyze the effects of replacing table salt with herbal salt on blood pressure values and urinary sodium excretion in people with hypertension. This study has a quantitative approach and quasi-experimental design, "cross-over" type, with a sample of hypertensive patients registered in three public health units in a municipality in the state of Mato Grosso. Data collection was carried out from May 2020 to May 2022. Through an interview, the questionnaire to identify sociodemographic variables and the "Medication Adherence Questionnaire - Qualiaids" (QAM-Q) were applied. Subsequently, anthropometric assessment and casual blood pressure measurements were performed. The research was divided into three stages: Stage 1 - the participants kept the usual use of table salt for seven days; Stage 2 - participants made exclusive use of five grams of salt per day for ten days; Stage 3 - participants used only herbal salt to prepare meals for 10 days. Residential blood pressure monitoring and urinary sodium measurement were performed at all stages. Descriptive analyzes were performed using the IBM Statistical Package for Social Science - SPSS® program, version 25.0. The One Way test was used for comparisons between the paired mean values. Results were expressed as mean values, standard deviation (sd), minimum, maximum, and median. For statistical difference, p<0.05 was considered. Participated in the research 24 individuals, with a mean age of 63.2 ± 10 years, most of them was women (54.2%), who live with a partner (70.8%), self-declared white skin color (54.2%), with an average of 7.6 years of formal education and retired (45.8%). Regarding clinical variables, it was observed a predominance of participants with optimal blood pressure (45.8%), in the overweight category (45.8%), with high cardiovascular risk according to the waist-to-height ratio (87.5%), and very high risk according to waist circumference measurement (54.1%), 62.5% were adherent to the treatment. When comparing the three stages, there was a significant reduction in the values of systolic blood pressure (p=0.003) and diastolic blood pressure (p=0.001), with no difference in the variables salt consumption (p=0.66) and urinary sodium excretion (p=0.66). Although the use of herbal salt is an interesting and innovative non-drug strategy for blood pressure control, participants did not significantly adhere to the proposed intervention. Nevertheless, it should be noted that the monitoring of sodium consumption is essential for the evaluation of the use of salt by the population and to implement measures aimed at reducing blood pressure and preventing cardiovascular events

Building capacity in reducing population dietary sodium intake in the Americas / Creación de capacidad para reducir la ingesta de sodio en los alimentos a nivel de la población en la Región de las Américas / Desenvolvimento de capacidade para a redução da ingestão alimentar de sódio pela população das Américas

ABSTRACT Objective. To present some resources developed as part of the technical support of the Pan American Health Organization (PAHO) to Member States to reduce population dietary sodium intake, and to discuss the main challenges and opportunities to accelerate action toward sodium intake reduction in the Americas. Methods. Sources of information include a mapping of salt reduction policies conducted in 2019, reports from working group meetings, interviews conducted in 2020 and 2021 in seven countries, and technical documents developed around the Updated PAHO Regional Sodium Reduction Targets. Results. These tools show that, despite progress, challenges to succeed in this agenda persist. Priority given to sodium reduction is low in most countries, with insufficient resource allocation. There is a lack of intersectoral coordinated action, and a systemic approach to food systems is commonly missing. Surveillance mechanisms of sodium intake are insufficient, and industry interference in policy processes is commonly identified, undermining policy progress and success. There are also important regional opportunities to address these challenges. These include common ground for future collaborations by updating, strengthening, and complementing these existing tools, and technical and financial support for data generation. Conclusions. PAHO is committed to continue to support countries in the process of promoting, implementing, and monitoring cost-effective sodium reduction interventions. One key policy priority in this agenda is the adoption of the Updated PAHO Regional Sodium Reduction Targets with a mandatory approach, together with the comprehensive and complementary implementation of other strategies. Strong political will and commitment of countries will be critical to translate goals into concrete achievements in the Americas.

RESUMEN Objetivo. Presentar algunos recursos elaborados como parte del apoyo técnico brindado por la Organización Panamericana de la Salud (OPS) a los Estados Miembros para reducir la ingesta de sodio en los alimentos a nivel de la población y abordar los principales desafíos y oportunidades para acelerar las medidas de reducción de la ingesta de sodio en la Región de las Américas. Métodos. Entre las fuentes de información se encontraron un mapeo de las políticas de reducción de la sal realizado en el 2019, varios informes de reuniones de grupos de trabajo, entrevistas realizadas en siete países entre el 2020 y el 2021, y documentos técnicos acerca de las metas regionales actualizadas de la OPS para la reducción del sodio. Resultados. Estas herramientas muestran que, a pesar de los avances, persisten los desafíos en el logro de esta agenda. La prioridad dada a la reducción del sodio en la mayoría de los países es baja y la asignación de recursos es insuficiente. No hay coordinación intersectorial y por lo general no se adopta un enfoque sistémico para los sistemas alimentarios. Los mecanismos de vigilancia de la ingesta de sodio son insuficientes y es común que haya interferencia de la industria en los procesos que siguen las políticas, lo que socava su progreso y éxito. Hay importantes oportunidades regionales para abordar estos desafíos, como un terreno común para futuras colaboraciones mediante la actualización, el fortalecimiento y la complementación de las herramientas existentes, y el apoyo técnico y financiero para la generación de datos. Conclusiones. La OPS mantiene su compromiso de seguir apoyando a los países en el proceso de promoción, ejecución y seguimiento de intervenciones costo-eficaces para la reducción del sodio. Una prioridad política clave en esta agenda es la adopción con carácter obligatorio de las metas regionales actualizadas de la OPS para la reducción del sodio, junto a la ejecución integral y complementaria de otras estrategias. Una fuerte voluntad política y el compromiso de los países serán fundamentales para traducir estos objetivos en logros concretos en la Región de las Américas.

Abordaje anterior de la cadera: historia y beneficios / Anterior Approach to the Hip: History and Benefits

La artroplastia de cadera es uno de los tratamientos quirúrgicos más exitosos en la cirugía ortopédica. Actualmente existe un mayor interés en el abordaje anterior para artroplastias de cadera determinado por la creencia de que al ser intermuscular puede provocar una disminución del dolor, una recuperación más rápida, mejor estabilidad de la cadera y menor riesgo de luxación después de la cirugía comparativamente. Es propósito de este artículo revisar la historia del abordaje anterior de la articulación de la cadera, su vía intermuscular de acceso y los principales beneficios que posee. Popularizado por Smith-Petersen en 1917, el abordaje anterior de la cadera debe su primera referencia escrita a Carl Hueter. Todos los abordajes de la cadera han demostrado ser seguros y eficaces, con ventajas y desventajas. Se requieren estudios a largo plazo de un mayor número de pacientes para demostrar un beneficio de costo y una mayor calidad en la atención médica(AU)

Hip replacement is one of the most successful surgical treatments in orthopedic surgery. There is currently greater interest in the anterior approach to hip arthroplasties determined by the belief that being intramuscular it can lead to less pain, faster recovery, better hip stability and comparatively less risk of dislocation after surgery. The purpose of this article is to review the history of the anterior approach to the hip joint, its intramuscular access route and its main benefits. Popularized by Smith-Petersen in 1917, the anterior approach to the hip owes its first written reference to Carl Hueter. All hip approaches have been shown to be safe and effective, with advantages and disadvantages. Long-term studies of larger numbers of patients are required to demonstrate cost benefit and higher quality of medical care(AU)

Psicossociologia com comunidades: abordagens sentipensantes como emergência na América Latina / Psychosociology with Communities: Sentipensantes Approaches as Urgency in Latin America / Psicosociología con comunidades: enfoques sentipensantes como emergencia en América Latina

No campo da Psicossociologia, defende-se a reorientação dos processos interventivos, bem como formulações psicossociológicas sentipensantes em consonância com as demandas da conjuntura atual. Por meio de revisão bibliográfica, o artigo tem por objetivo ensaiar perspectivas teóricas e conceituais a respeito dos percursos latino-americanos feitos por Maritza Montero, Maria Inácia D'Ávila Neto, Ignacio Martín-Baró, Paulo Freire e Orlando Fals Borda. Vislumbramos a proposição de um quadro no qual a Psicossociologia não seria uma ciência "de" comunidades, mas sim "com" comunidades, por se comprometer com a criação de conexões entre o individual-psicológico-singular-subjetivo com o coletivo-social-popular-político, de modo a abarcar as diferentes influências existentes nas interações comunitárias. Portanto, este trabalho se propõe a refletir sobre uma lógica contra-hegemônica e descolonizadora ao caminhar por trilhas suleadoras, sentipensantes e libertadoras. Nesse sentido, reforçamos que uma "Psicossociologia com comunidades" deve se empenhar em fortalecer os encontros e promover confluências, engendrando processos de produção coletiva de conhecimentos contextualizados e críticos sobre as realidades comunitárias.

In the field of Psychosociology, it is advocated the reorientation of interventional processes, as well as psychosociological formulations in line with the demands of the current situation. Through bibliographic review, the article aims to rehearse theoretical and conceptual perspectives on the Latin American paths taken by Maritza Montero, Maria Inácia D'Ávila Neto, Ignacio Martín-Baró, Paulo Freire and Orlando Fals Borda. We envision the proposition of a framework in which Psychosociology would not be a science "of" communities, but "with" communities because it is committed to creating connections between the individual-psychological-singular-subjective with the collective-social-popular-political, in order to encompass the different influences existing in community interactions. Therefore, this work proposes to reflect on a counter-hegemonic and decolonizing logic when walking along suleadoras, sentipensantes and liberating trails. In this sense, we reinforce that a "Psychosociology with communities" must strive to strengthen the meetings and promote confluences, engendering processes of collective production of contextualized and critical knowledge about the community realities.

En el campo de la Psicosociología se aboga por la reorientación de los procesos intervencionistas, así como por formulaciones psicosociológicas acordes con las exigencias de la situación actual. A través de una revisión bibliográfica, el artículo pretende ensayar perspectivas teóricas y conceptuales sobre los caminos latinoamericanos tomados por Maritza Montero, Maria Inácia D'Ávila Neto, Ignacio Martín-Baró, Paulo Freire y Orlando Fals Borda. Visualizamos la propuesta de un marco donde la Psicosociología no sería una ciencia "de" comunidades, sino más bien "con" comunidades porque se compromete a crear conexiones entre lo individual-psicológico-singular-subjetivo con lo colectivo-social-popular-político, con el fin de abarcar las diferentes influencias existentes en las interacciones comunitarias. Por ello, este trabajo propone reflexionar sobre una lógica contrahegemónica y descolonizante al caminar por senderos suleadoras, sentipensantes y liberadores. En este sentido, reforzamos una "Psicosociología con comunidades" debe buscar fortalecer los encuentros y promover confluencias, engendrando procesos de producción colectiva de conocimiento contextualizado y crítico sobre las realidades comunitarias.

Does evaluation of tumor volume or/both origination site better guide to optimal surgery for inverted papilloma? / A avaliação do volume do tumor e/ou dos seus locais de origem fornece a melhor orientação para a técnica cirúrgica ideal do papiloma invertido?

Abstract Introduction Sinonasal inverted papilloma is noted for its high rate of recurrence. Staging systems aid to reduce recurrence and avoid excessive surgeries by guiding the selection of the optimal surgical approach. Objective To evaluate the effectiveness of different endoscopic approaches in inverted papilloma by assessing tumor origin site and tumor volume. Methods Krouse classification system that is based on tumor volume was used for staging; furthermore, tumor origin sites were grouped as lateral nasal wall, medial wall and other walls of maxillary sinus. The main treatment method for all patients was endoscopic sinus surgery. Endoscopic extended middle meatal antrostomy, endoscopic Caldwell-Luc and endoscopic medial maxillectomy were the additional surgery types performed in different combinations. Results Fifty-five patients (42 male) with a mean 54.9 ± 14.4 years of age were included. 37 patients were diagnosed with advanced stage inverted papilloma (67.2 %). Recurrence was observed in 12 patients (21.8 %). In early stage lateral nasal wall origination, no recurrence was observed in the simple tumor resection group (0/10). In early stage medial wall origination, no recurrence was observed in the extended middle meatal antrostomy group (0/8). In advanced stage medial wall origination, the recurrence rates of extended middle meatal antrostomy, extended middle meatal antrostomy + endoscopic Caldwell- Luc and endoscopic medial maxillectomy were 100.0 %, 53.8 % and 13.6 %, respectively (p = 0.002). In advanced stage other walls of maxillary sinus origination, recurrence rates of extended middle meatal antrostomy + endoscopic Caldwell-Luc and endoscopic medial maxillectomy were 20 % and 16.6 %, respectively (p = 0.887). Conclusion Tumor origin site, tumor stage and surgery types show an impact on recurrence. Despite the fact that tumor origin site singly could lead to appropriate selection of the surgery type in most cases, tumor stage carries substantial importance in selection of surgery type for sinonasal-inverted papilloma. An operation plan regarding both tumor volume and tumor origin site may aid surgeons in selecting optimal endoscopic surgical method to avoid recurrence or excessive surgeries.

Resumo Introdução O papiloma invertido nasossinusal é conhecido por sua alta taxa de recorrência. Os sistemas de estadiamento ajudam a reduzir a recorrência e evitar cirurgias excessivas e orientam a seleção da abordagem cirúrgica ideal. Objetivo Avaliar a eficácia de diferentes abordagens endoscópicas no papiloma invertido, de acordo com o local de origem e o volume do tumor. Método Para o estadiamento, usou-se o sistema de classificação de Krouse, baseado no volume do tumor; além disso, os tumores foram agrupados de acordo com seus locais de origem: parede nasal lateral, parede medial e outras paredes do seio maxilar. O principal método de tratamento para todos os pacientes foi a cirurgia endoscópica nasossinusal. Foram feitos, em diferentes combinações, os seguintes tipos de cirurgia: antrostomia estendida do meato médio, Caldwell-Luc endoscópica e maxilectomia medial endoscópica. Resultados Foram incluídos 55 pacientes (42 homens) com média de 54,9 ± 14,4 anos. Trinta e sete pacientes foram diagnosticados com papiloma invertido avançado (67,2%). Foi observada recorrência em 12 pacientes (21,8%). No estágio inicial com origem na parede nasal lateral, não foi observada recorrência no grupo de ressecção simples de tumor (0/10). No estágio inicial com origem na parede medial, não foi observada recorrência no grupo de antrostomia estendida do meato médio (0/8). Com tumor em estágio avançado com origem na parede medial, as taxas de recorrência na antrostomia estendida do meato médio, antrostomia estendida do meato médio + Caldwell-Luc endoscópica e maxilectomia medial endoscópica foram de 100,0%, 53,8% e 13,6%, respectivamente (p = 0,002). No tumor em estágio avançado em outras paredes do seio maxilar, as taxas de recorrência na antrostomia estendida do meato médio + Caldwell-Luc endoscópica e maxilectomia medial endoscópica foram de 20% e 16,6%, respectivamente (p = 0,887). Conclusão O local de origem do tumor, o estágio do tumor e os tipos de cirurgia mostram impacto na recorrência. Apesar da consideração de que na maioria dos casos o local de origem do tumor pode, de forma isolada, orientar a seleção apropriada do tipo de cirurgia, o estágio do tumor tem importância substancial na seleção do tipo de cirurgia para papiloma invertido nasossinusal. Um planejamento cirúrgico considerando tanto o volume quanto o local de origem do tumor pode ajudar os cirurgiões a selecionar o tipo ideal de cirurgia endoscópica para evitar recorrências ou remoções excessivas.

Enfoques de aprendizaje en estudiantes argentinos de nivel secundario y universitario / Learning approaches in Argentinean high school and university students

Resumen Los enfoques de aprendizaje permiten conocer el modo en que los estudiantes perciben y aprenden los contenidos académicos. El sistema universitario local registra elevadas tasas de fracaso y deserción estudiantil al inicio del ciclo académico. Por esta razón, se analizan los aprendizajes de estudiantes de nivel secundario y universitario. Se aplicó el Cuestionario de Procesos de Estudio Dos Factores a 797 estudiantes (44 % secundarios; 56 % universitarios). Se analizó primero la estructura interna del instrumento con muestras de estudiantes de nivel secundaria y universitario. Luego un MANCOVA halló efectos multivariados de las variables sexo, nivel educativo y la interacción entre sexo y nivel educativo, sobre los enfoques de aprendizaje. Se concluye que el cuestionario presenta adecuadas propiedades psicométricas en ambos grupos de estudiantes. Además, se observaron diferencias en los enfoques entre estudiantes de secundaria y universitario, pudiéndose planificar actividades educativas orientadas a mejorar los resultados académicos durante el período de transición.

Abstract Learning approaches allow us to know how students perceive and learn academic content. The local university system records high rates of student failure and dropout at the beginning of the academic year. For this reason, the learning approaches of high school and university students are analyzed. The Two-Factor Study Process Questionnaire was applied to 797 students (44 % high school; 56 % university students). The internal structure of the instrument was first analyzed with samples of high school and university students. Then a MANCOVA found multivariate effects of the variables sex, educational level and interaction between sex and educational level, on learning approaches. It is concluded that the questionnaire presents adequate psychometric properties in both groups of students. In addition, differences in approaches were observed between high school and university students, and educational activities aimed at improving academic results during the transition period can be planned.
