Ciclismo recreacional e mobilidade urbana: análise das motivações dos ciclistas de Blumenau/SC / Urban mobility: an analysis of the motivations of cyclists in Blumenau/SC

A motivação é um fenômeno complexo que impulsiona as ações humanas. O diagnóstico de tais interesses oferece elementos de reflexão para a promoção de atividades e a implementação de políticas públicas. Neste contexto, o presente trabalho tem o objetivo de analisar as motivações dos praticantes de ciclismo recreacional de Blumenau/SC, município com uma população de 363 mil habitantes e uma malha cicloviária de 137 quilômetros. A coleta dos dados empíricos da pesquisa ocorreu por meio da aplicação de um questionário. Ao final, obteve-se uma amostra de 304 respondentes. Os resultados do estudo indicam a motivação para as atividades físicas ocupa papel central na relação com outros fatores de interesse, contribuindo para a superação de aspectos eventualmente desencorajadores. Em contrapartida, praticantes que têm outras motivações, como a interação social e o desenvolvimento pessoal, dependem mais de estímulos encorajadores, o que sugere que em tais casos existe a necessidade de maior incentivo para a prática do ciclismo recreacional. As conclusões deste estudo são relevantes para planejadores urbanos e gestores de comunicação. Ao mensurar a pertinência de causas motivadoras e desmotivadoras do ciclismo, os resultados da pesquisa indicam a importância de investir em infraestrutura adequada como a expansão da rede cicloviária e a criação de campanhas de divulgação, a fim de promover a bicicleta como meio de transporte e/ou recreação.

Motivation is a complex phenomenon that drives human actions. Diagnosing these interests provides elements for reflection in promoting activities and implementing public policies. In this context, the present study aims to analyze the motivations of recreational cyclists in Blumenau, SC (Brazil), a city with a population of 363,000 inhabitants and a cycling network of 137 kilometers. Empirical data for the research were collected through a questionnaire. Ultimately, a sample of 304 respondents was obtained. The study's results indicate that motivation for physical activities plays a central role in the relationship with other factors of interest, contributing to overcoming potentially discouraging aspects. Conversely, individuals motivated by other factors, such as social interaction and personal development, rely more on encouraging stimuli, suggesting that in such cases there's a need for greater incentives for recreational cycling. The conclusions of this study are relevant for urban planners and communication managers. By assessing the relevance of motivating and demotivating factors in cycling, the research results underscore the importance of investing in appropriate infrastructure, such as expanding the cycling network and launching promotional campaigns, to promote cycling as a means of transportation and/or recreation.

Retrospective review of medicine utilization for noncommunicable diseases in three public sector pharmacies in Jamaica / Revisión retrospectiva del uso de medicamentos para enfermedades no transmisibles en tres farmacias del sector público de Jamaica / Revisão retrospectiva do uso de medicamentos para doenças não transmissíveis em três farmácias da rede pública na Jamaica

ABSTRACT Objective. The rational use of medicines offers a cost-saving strategy to maximize therapeutic outcomes for developing and developed countries. The aim of this study was to evaluate the rational use of medicines for selected noncommunicable diseases (NCDs) at three pharmacies at public hospitals in Jamaica using the World Health Organization's (WHO's) prescribing indicators. Methods. In this retrospective cross-sectional study, prescriptions for adult outpatients containing at least one medicine for cardiovascular disease, diabetes, cancer, chronic obstructive pulmonary disease or asthma that were filled between January and July 2019 were reviewed using WHO's prescribing indicators for the rational use of medicines. Data were analyzed and expressed as descriptive and inferential statistics. For all analyses conducted, significance was determined at P < 0.05. Results. A total of 1 500 prescriptions covering 5 979 medicines were reviewed; prescriptions were mostly written for female patients aged 42-60 years. Polypharmacy was observed in 35.6% (534) of prescriptions, and there was an average of 4 medicines per prescription, with a maximum of 17. Most of the prescriptions at each site were filled, with the main reason for not dispensing a medicine being that it was out of stock. Generic prescribing was high for all sites, accounting for more than 95% (5 722) of prescribed medicines. There was full compliance with prescribing according to the WHO Model List of Essential Medicines at two of the sites, but it was just off the target at Site 1, by 1.4%. Conclusions. The WHO guidelines for the rational use of medicines were followed with respect to the proportion of medicines prescribed from the WHO Model List and the proportion of antibiotics prescribed. The number of medicines per prescription and the proportion of medicines prescribed by generic name did not meet the WHO criteria. However, prescribing was aligned with treatment guidelines for the selected NCDs.

RESUMEN Objetivo. El uso racional de los medicamentos proporciona una estrategia de ahorro de costos para maximizar los resultados terapéuticos tanto en los países en desarrollo como en los países desarrollados. El objetivo de este estudio fue evaluar el uso racional de medicamentos para algunas enfermedades no transmisibles (ENT) seleccionadas en tres farmacias de hospitales públicos de Jamaica, usando los indicadores de prescripción de la Organización Mundial de la Salud (OMS). Métodos. En este estudio transversal retrospectivo se examinaron las prescripciones realizadas a pacientes ambulatorios adultos que incluían al menos un medicamento para enfermedades cardiovasculares, diabetes, cáncer, enfermedad pulmonar obstructiva crónica o asma, dispensadas entre enero y julio del 2019, utilizando los indicadores de prescripción para el uso racional de medicamentos de la OMS. Los datos se analizaron y expresaron mediante estadística descriptiva e inferencial. Para todos los análisis realizados se estableció un nivel de significación de p <0,05. Resultados. Se examinó un total de 1 500 prescripciones que incluían 5 979 medicamentos; la mayor parte de ellas correspondían a pacientes de sexo femenino de 42 a 60 años. Se observó que había polimedicación en el 35,6% (534) de las prescripciones, con un promedio de 4 y un máximo de 17 medicamentos por receta. En todos los centros se dispensó la mayor parte de los medicamentos prescritos, y el motivo principal para no hacerlo fue la falta de existencias del medicamento en cuestión. La prescripción de genéricos fue elevada en todos los centros y supuso más del 95% (5 722) de los medicamentos prescritos. En dos centros la prescripción se realizó en su totalidad de acuerdo con la Lista Modelo de Medicamentos Esenciales de la OMS, pero en el centro 1 no se alcanzó el objetivo por un 1,4%. Conclusiones. Se siguieron las directrices de la OMS para el uso racional de medicamentos en cuanto a la proporción de medicamentos prescritos de la Lista Modelo de la OMS y la proporción de antibióticos prescritos. El número de medicamentos por receta y la proporción de medicamentos prescritos mediante su nombre genérico no cumplieron con los criterios de la OMS. Sin embargo, las prescripciones estaban en consonancia con las directrices de tratamiento de las enfermedades no transmisibles seleccionadas.

RESUMO Objetivo. O uso racional de medicamentos é uma estratégia de contenção de custos para maximizar os resultados terapêuticos em países desenvolvidos e em desenvolvimento. O objetivo deste estudo foi avaliar o uso racional de medicamentos para algumas doenças não transmissíveis selecionadas em três farmácias de hospitais públicos na Jamaica a partir dos indicadores de prescrição preconizados pela Organização Mundial da Saúde (OMS). Métodos. Estudo transversal retrospectivo que avaliou receitas médicas de pacientes ambulatoriais adultos contendo pelo menos um medicamento prescrito para doença cardiovascular, diabetes, câncer, doença pulmonar obstrutiva crônica ou asma e dispensadas entre janeiro e julho de 2019. A avaliação foi realizada a partir dos indicadores de prescrição preconizados pela OMS para o uso racional de medicamentos. Os dados obtidos foram analisados por meio de estatísticas descritivas e inferenciais. O nível de significância de p <0,05 foi adotado em todas as análises. Resultados. Ao todo, foram analisadas 1 500 receitas médicas compreendendo 5 979 medicamentos. Em sua maioria, as receitas foram prescritas para pacientes do sexo feminino com idades entre 42 e 60 anos. A polifarmácia foi observada em 35,6% (534) das receitas; em média, foram prescritos 4 medicamentos, até um máximo de 17. As farmácias estudadas dispensaram a maior parte dos medicamentos receitados. O principal motivo para não fornecer algum medicamento foi o desabastecimento. O percentual de medicamentos genéricos foi alto em todos os locais, representando mais de 95% (5 722) do volume receitado. Houve plena observância da Lista Modelo de Medicamentos Essenciais da OMS nas receitas analisadas em dois dos locais estudos, e observância quase completa (diferença de 1,4%) no local 1. Conclusões. As diretrizes da OMS de uso racional de medicamentos foram cumpridas no que se refere ao percentual de medicamentos receitados de acordo com a Lista Modelo da OMS e o percentual de antibióticos receitados. Os critérios da OMS não foram cumpridos quanto ao número de medicamentos por receita e ao percentual receitado usando o nome genérico. Porém, os medicamentos foram receitados de acordo com as diretrizes terapêuticas para as doenças não transmissíveis selecionadas.

Description of the S-Apple mixed rotation and transposition flap: preliminary note / Descrição do retalho misto de rotação e transposição S-Apple: nota prévia

Introduction: The flaps, whose function is to reduce or redirect tension during a closure, are classified based on their primary movement: transposition, advancement, and rotation, each with its characteristics, indications, and peculiarities. Combining the qualities of the transposition flaps with those of rotation, which make up the S-Apple flap, makes it more versatile and with better aesthetic results than the bilobed flap, which denotes the archetype for the appearance of the S-Apple. Method: Having the rotation and transposition flaps as an archetype, four flaps are made in the S-Apple flap, which are rotated and transposed to close the defect. This is excised in a circular format for the oncological safety of margins. The "S" of the flap is traced at a 30º angle in relation to the defect. The arm dimension must be the same diameter as the defect, with the flaps transposed as in a z-plasty, and the flap rotated to cover the defect, resulting from the exeresis of the lesion. Results: No necrosis, infection, dehiscence, recurrences, trapdoor scars, or rotation point elevation were observed. The scars were classified as satisfactory and extremely satisfactory. Conclusion: The S-Apple flap proved versatile and easy to mark with excellent aesthetic and functional results.

Introdução: Os retalhos, com função de reduzir ou redirecionar a tensão durante um fechamento, são classificados com base em seu movimento primário: transposição, avanço e rotação, cada um com suas características, indicações e peculiaridades. O arregimentar das qualidades dos retalhos de transposição com os de rotação, que compõem o retalho S-Apple, tornam-no mais versátil e com melhores resultados estéticos em relação ao retalho bilobado, que denota o arquétipo para o surgimento do S-Apple. Método: Tendo como arquétipo os retalhos de rotação e transposição, no retalho S-Apple são confeccionados quatro retalhos, que são rotacionados e transpostos para fechamento do defeito. Este é excisado em formato circular para segurança oncológica de margens. O "S" do retalho é traçado em um ângulo de 30º em relação ao defeito. A dimensão do braço deve ser do mesmo diâmetro do defeito, sendo os retalhos transpostos como em uma zetaplastia e o retalho rotacionado para cobrir o defeito, resultante da exérese da lesão. Resultados: Não foram observadas necroses, infecção, deiscências, recidivas, cicatrizes em alçapão e elevação em ponto de rotação. As cicatrizes foram classificadas como satisfatórias e extremamente satisfatórias. Conclusão: O retalho S-Apple se mostrou um retalho versátil de fácil marcação com excelentes resultados estéticos e funcionais.

Application value of ERCP in the diagnosis and treatment of pancreaticobiliary maljunction in children / 中华胰腺病杂志

Objective:To investigate the application value of endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis and treatment of pancreaticobiliary maljunction (PBM) in children.Methods:The clinical data of 77 PBM children who underwent ERCP in General Surgery Department of Children's Hospital affiliated to Nanjing Medical University between January 2018 and December 2021 were retrospectively evaluated. Clinical characteristics, classification and post-operative nursing interventions were summarized, and vital signs, changes of biochemical markers and the occurrence of postoperative complications were compared and recorded.Results:77 patients were classified according to Japanese Study Group on Pancreaticobiliary Maljunction (JSGPM), including 34 patients with type A, 18 patients with type B, 21 patients with type C, and 4 patients with type D. There were 68 patients with congenital bile duct dilation and 9 patients without congenital bile duct dialtion. 92 ERCP procedures were performed under general anesthesia, and 91 cases were successful with a success rate of 98.91%. Among these cases, including 7 cases of endoscopic sphincterotomy, 28 cases of endoscopic balloon dilation of the nipple, 22 cases of endoscopic probe dilation, 22 cases of endoscopic stone removal by balloon or basket, 35 cases of endoscopic retrograde biliary stent drainage, 4 cases of endoscopic pancreatic duct drainage, 18 cases of endoscopic nasobiliary drainage, 2 cases of endoscopic nasobiliary drainage, and 14 cases of biliary stent removal. In 77 children with PBM, body temperature, FLACC score, and laboratory-related biochemical indexes including direct bilirubin, serum amylase, ALT, AST and CGT decreased significantly after ERCP, and all the differences were statistically significant (all P value <0.001). The incidence of postoperative complications was 15.38%(14/91), including hyperamylasemia in 9 cases (9.89%) and abdominal pain in 5 cases (5.49%). Conclusions:ERCP is safe and effective in the treatment of abnormal confluence of pancreatic duct in children.

Paying close attention to the therapeutic effect of brolucizumab on polypoidal choroidal vasculopathy and its clinical application / 中华实验眼科杂志

Polypoidal choroidal vasculopathy (PCV) occurs in the middle-aged and elderly population and is characterized by abnormal intrachoroidal vascular patterns such as branching choroidal vascular networks and polypoidal dilatation of vessel terminals, subretinal orange nodular lesions and hemorrhagic or plasma retinal pigment epithelial detachment (PED), which can cause retinal hemorrhage or vitreous hematopoiesis and is one of the major blinding fundus lesions.Intravitreal injection of anti-vascular endothelial growth factor (VEGF) drugs is currently the main method of PCV treatment, and has certain advantages in eliminating abnormal vascular networks and removing polypoidal lesions, reducing vascular exudation and promoting exudate absorption, and improving visual prognosis.However, frequent intravitreal drug injections increase the risk of infection and the treatment burden for patients.In addition, the high recurrence rate after treatment poses a significant challenge to clinical practice, so the search for new therapeutic agents that are durable and less costly is a focus of clinical research in PCV.The literature from abroad suggests that brolucizumab is a novel small-molecule anti-VEGF humanized monoclonal antibody with the advantages of high tissue penetration, high local drug concentration and bioavailability, small injectable dose, long-lasting efficacy and long injection interval, which brings new hope for the clinical treatment of PCV and improving the prognosis of affected eyes.Although the efficacy and safety of brolucizumab in the treatment of PCV have been well documented, the literature is mainly from Japan, India and Korea, and clinical practice data from China are still lacking.With the approval of the drug in several countries, it is believed that more PCV patients could benefit from this treatment in the near future.Ophthalmologists and researchers in China should closely follow the progress of brolucizumab in the treatment of PCV.

Liquid biopsy is a new type of examination method with peripheral blood as the main examination subject. Compared with conventional tumor tissue pathology, liquid biopsy has less trauma, and the detection items can more accurately represent a certain tumor tissue group, more directly reflect the biological behavior of tumor tissue in the patient′s body. It is widely used in tumor screening, staging and grading, tumor individualized treatment monitoring, and prognosis evaluation. The following is mainly about the diagnosis, therapeutic effect evaluation and prognosis prediction of liquid biopsy in HCC from three aspects: circulating tumor DNA (ctDNA), exosome and circulating tumor cells (CTC), and the challenges faced by liquid biopsy technology at present are briefly described and its future development is prospected.

Application of 3D printing in surgical treatment of hepatobiliary malignancies / 国际外科学杂志

At present, surgical treatment is the most effective method for the treatment of hepatobiliary malignant tumor. However, due to the complex anatomical structure of hepatobiliary region, accompanied by vascular variation, and with the continuous update of medical concepts, the requirements for surgery are more strict. Traditional imaging examination has reached a bottleneck in the support of surgical treatment, while 3D printing technology is compared with the former. It showed strong advantages in preoperative program planning and improving the effect of intraoperative precise resection. At the same time, it also shows great potential for medical assistance and disease treatment in the production of bioactive models, and 3D printing technology has obviously enhanced the understanding of surgery for young doctors, and medical staff can create a variety of highly practical 3D printing models under the existing conditions. In the future, it is expected to overcome the limitations of materials and technology and bring higher therapeutic benefits for the majority of patients.

Analysis of therapeutic effect on the spontaneous isolated superior mesenteric artery dissection with endovascular therapy / 国际外科学杂志

Objective:To discuss the clinical effect of endovascular treatment of 15 patients with spontaneous isolated superior mesenteric artery dissection(SISMAD).Methods:The clinical data of 15 patients with SISMAD treated with endovascular stent in Beijing Friendship Hospital Affiliated to Capital Medical University from January 2016 to July 2022 were collected and analyzed. The white blood cell, neutrophil percentage (NEUT%) and D-Dimer at admission, day 1 and day 3 after operation were analyzed and compared retrospectively. The time of abdominal pain at admission, YOO classification, angle from superior mesenteric artery to abdominal aorta(ASA), conservative treatment time, operation time, type and length of stent, vascular remodeling rate and long-term patency rate of stent were analyzed. The measurement data conforming to normal distribution was expressed as mean ± standard deviation ( ± s), t-test was used for comparison between the two groups. Measurement data of skewed distribution were expressed as M ( Q1, Q3), and non-parametric test was used for comparison between groups. Count data were expressed as rate or component ratio(%). The same variable was compared at different time points by repeated measurement data analysis of variance. Results:There were significant differences in white blood cell, NEUT% and D-Dimer between admission and postoperative day 3 in 15 patients. The time to admission for abdominal pain was 24.0(15.0, 78.0) hours. IVS type accounted for 46.7% of YOO type, and the ASA beyond 60° accounted for 66.7%. The conservative treatment time was (34.0±8.6) hours, moreover, the operation time was(153.0±37.8) min. Besides, self-expanding bare stent accounted for 85% of the stent types, moreover, the length of the stents beyond 60 cm was 50%. All patients were followed up for more than 24 months, and the vascular remodeling rate was(89.7±9.7)%.Conclusion:Endovascular self-expanding thin-wall stent placement has better vascular remodeling rate and patency rate for patients with IVS type.

Prevention and treatment of perioperative venous thromboembolism in colorectal cancer patients / 国际外科学杂志

Venous thromboembolism (VTE) is a common perioperative complication in patients with malignant tumors. Factors such as colorectal cancer itself and surgical treatment can increase the risk of perioperative VTE. In recent years, with the development of the concept of enhanced recovery after surgery, the understanding of cancer-associated venous thrombosis has deepened, and significant progress has been made in the risk assessment, prevention and treatment strategies of cancer-associated VTE. This article will review the pathogenesis, risk factors, risk assessment, prevention and treatment strategies of colorectal cancer-associated VTE, in order to provide evidence-based medical basis and research ideas for the standardized management and future research of colorectal cancer-associated VTE.

Rediscussion of the reoperation of differentiated thyroid cancer / 国际外科学杂志

The treatment concept and standardization of primary surgery for patients with differentiated thyroid cancer vary among different regions and different treatment centers in the same region, resulting in different reoperation rates for patients. Intraoperative experience, preoperative evaluation, surgical approach, and procedure may all influence the success rate of reoperation. In order to reduce the risk of surgery and complications, reoperation should be treated standardized, while combining the current diagnosis and treatment techniques to provide individualized treatment options for reoperation patients, under the premise of ensuring efficacy, to broaden the indications of surgery, make large incisions into small incisions, and change traditional open surgery into minimally invasive surgery, improve the quality of life of patients and confidence in coping with social stress. This paper will summarize the main content of preoperative assessment at the time of reoperation in patients with differentiated thyroid cancer, analyze the notes and rationally developing a surgical plan for patients, in the hope of attracting the same emphasis and normalizing the reoperation treatment, so as to achieve reoperation of the tumor R0 resection.

Current status of diagnosis and treatment of senile differentiated thyroid cancer / 国际外科学杂志

As the elderly population continues to rise, the issue of disease diagnosis and treatment in the elderly population is becoming a hot topic of concern. Differentiated thyroid cancer is the most common endocrine malignancy in the world, and patients with differentiated thyroid cancer in the elderly have a worse clinical prognosis and higher risk of recurrence and metastasis. Moreover, due to the special characteristics and complexity of the elderly population, patients with differentiated thyroid cancer in the advanced age group have special features in terms of morbidity, preoperative diagnosis, treatment options, and postoperative management compared with other populations. This article reviews the current status of diagnosis and treatment of differentiated thyroid cancer in the elderly, taking into account the findings and opinions of domestic and international studies.

Historical Evolution and Modern Research Progress of Processing of Notoginseng Radix et Rhizoma / 中国实验方剂学杂志

By reviewing the relevant literature of ancient herbal works and modern codices， this paper sorted out the historical evolution and developmental venation of processing of Notoginseng Radix et Rhizoma. On this basis， the modern research of processed products of Notoginseng Radix et Rhizoma was used as the breakthrough point to analyze the literature in terms of processing technology， chemical composition changes and changes in pharmacological effects before and after processing. According to the research status of processing of Notoginseng Radix et Rhizoma， some existing problems were analyzed in this paper， such as not many ancient processing methods used in modern time， lack of standardized research on processing technology. And saponins， polysaccharides， amino acids， flavonoids and other chemical components in Notoginseng Radix et Rhizoma may change to different degrees before and after processing， which was the main reason for the difference of efficacy before and after processing. However， the current research on the pharmacological effects of Notoginseng Radix et Rhizoma mainly focuses on raw products， resulting in a lack of in-depth research on the transformation mechanism of Notoginseng Radix et Rhizoma in processing difference， and the scientific connotation of "Shengxiao Shubu" has not been clearly elaborated， which is not conducive to the standardized clinical use of drugs. Therefore， it is necessary to further analyze the material basis of Notoginseng Radix et Rhizoma and its processed products， and to explore the change rule of chemical components before and after processing and its correlation with pharmacodynamic activity， so as to clarify the processing mechanism for providing scientific basis for its standardized processing， quality control and clinical rational use.
