RESUMO
The payment methods,such as Diagnosis Related Group(DRG)for hospitalization and capitation for outpatient treat-ment,have achieved positive results in protecting the rights and interests of insured persons and improving the efficiency of the use of medical insurance funds.However,for patients with chronic diseases and rehabilitation nursing,the hospitalization period is long and the conditions complicated,and the payment method of DRGs is not reasonable.It analyzes the experiences of paying for long-term hospital cases in the US.and Germany from the aspect of reform process,payment method and regulatory measures.In order to pro-vide references for the reform of per-diem payment in rehabilitation nursing and other long-term hospitalized cases,it puts forward suggestions from aspects of realizing value care,reflecting individual differences,exploring complex payment methods,improving data quality and establishing constraint mechanism.
RESUMO
Background N-hexane has been a widely used solvent in industrial production, but it is volatile at room temperature and can be accumulated in the body, and its prolonged occupational exposure may lead to serious chronic diseases in workers. Objective To use four risk assessment models to evaluate the health risk levels of n-hexane-exposed workers, discuss the applicability of the four models in the health risk assessment of n-hexane exposure, and make an important supplement to the health risk assessment of n-hexane in China. Methods In 2022, a total of 167 jobs (1724 workers) exposed to n-hexane in 85 manufacturing enterprises in Jiangsu Province were selected, and a cross-sectional study was conducted and included questionnaire surveys and evaluation of on-site air n-hexane of each job. Subsequently, the China’s classification standards of occupational hazards at workplaces (China model), U.S. Environmental Protection Agency (EPA) model, Singapore semi-quantitative risk assessment model (Singapore model), and the International Council on Mining and Metals (ICMM) model were applied to the quantitative, semi-quantitative, and qualitative assessments of the occupational health risk level of n-hexane-exposed workers. Results All job’s 8-h time-weighted average concentrations (CTWA) of n-hexane were within the national occupational exposure limits (OELs). The results of the China model graded all jobs as relatively harmless. The Singapore model graded all jobs as low risk, except that two monitoring sites of adhesive jobs were assessed as medium risk. The ICMM quantitative model evaluated all jobs as intolerable for n-hexane airborne exposure, while the matrix method evaluated all jobs as low risk. The U.S. EPA model identified five sites involving painting, printing, and adhesive jobs as high risk and the other jobs as low risk. Conclusion Inconsistent grading results are observed by using the four models for the occupational health risk assessment of n-hexane exposure, that is, harmless for all jobs by China model, while medium and high risks by Singapore model and U.S. EPA model. Therefore, we recommend to combine the Singapore model and the U.S. EPA model with the China model to assess the occupational risk of n-hexane-exposed workers by considering actual concentrations of exposure.
RESUMO
Introducción: el 1 de enero de 1899 inició la ocupación militar de Cuba por Estados Unidos, cuyo objetivo fundamental fue sentar las bases de la futura República neocolonial. Objetivo: describir el comportamiento de la salud pública matancera durante el período de ocupación militar norteamericana 1899-1902. Materiales y métodos: se utilizó el método histórico descriptivo para estudiar el comportamiento de la salud pública matancera en el período de ocupación militar, y se realizó la revisión bibliográfica y documental. Resultados: no obstante los logros sociales -en especial en el ámbito de la salud pública-, las medidas y posiciones antinacionales que adoptó el gobierno interventor encontraron el rechazo de las clases y sectores interesados en lograr la absoluta soberanía de Cuba. Conclusiones: los matanceros realizaron notables esfuerzos para enfrentar la difícil situación sanitaria a través de la apertura de hospitales e instituciones, que brindaban servicios, sobre todo, a los sectores pobres de la población, y de la campaña de higienización para evitar la propagación de enfermedades y epidemias.
Introduction: the period of U.S. military occupation in Cuba officially began on January 1, 1899. Its main objective was to lay the foundation of the future neocolonial republic. Objective: to describe the behavior of Matanzas public health during the period of the US military occupation 1899-1902. Materials and methods: the historical descriptive method was used to study the behavior of Matanzas public health in the period of military occupation, and a bibliographic and documental review was conducted. Results: despite the social achievements- especially in the field of public health-, antinational measures and positions adopted by the intervening government found the rejection of the classes and sectors interested in achieving the absolute sovereignty of Cuba.

RESUMO
Background: Smartphone addiction among adolescents is an increasingly recognized problem worldwide. It affects the psychological well-being of an individual. Aim and objective: The current study aimed to assess smartphone addiction’s prevalence and its relation to depression among adolescents. Methods: This cross-sectional study was conducted among 400 school-going adolescents. Smartphone Addiction Scale - Short version (SAS-SV) and Patient Health Questionnaire (PHQ-9) were used to assess the prevalence of smartphone addiction and depression. Data were analyzed using Epi info software for windows (CDC, Atlanta). Statistical significance was set at p < 0.05. Results: The mean age of study participants was 14.4 years (SD=1.5 years). The prevalence of smartphone addiction was 23%, while depression was present among 45% of the study participants. Comparatively higher duration of smartphone use was significantly associated with smartphone addiction. Depression was significantly higher among smartphone addicts (77.2%) as compared to their counterparts (35.4%). Conclusion and Recommendation: The smartphone usage of adolescents, if not monitored, could lead to its addiction and thus increase the risk of depression among them. To prevent smartphone addiction, limiting children’s screen time is recommended. In this regard, parents can play a pivotal role by becoming responsible digital role models for their children.

RESUMO
OBJECTIVE To provide a reference for safe drug use in clinic. METHODS ADE reports related to nilotinib from the first quarter of 2007 to the fourth quarter of 2022 were collected from the US FDA adverse event reporting system database. The reporting odds ratio (ROR) and proportional reporting ratio (PRR) of disproportionality measures were used to mine potential ADE signals,which were compared with drug instruction and related case report, and were screened and analyzed according to the designated medical events (DME) list formulated by the European Medicines Agency. RESULTS Totally 23 332 cases of ADE with nilotinib as the primary suspected drug were reported. A total of 359 positive signals were obtained,involving 24 system organ classes (SOC),mainly concentrated in various examinations,heart organ diseases,vascular and lymphatic diseases,all kinds of nervous system diseases,etc. Among them,ADEs such as vertebral artery stenosis,coronary artery stenosis,arterial disease,liver infection and the second primary malignant tumor were not mentioned in the instructions. Seven DMEs were detected,of which bone marrow failure,pulmonary hypertension and deafness were not mentioned in the drug instruction. CONCLUSIONS The common ADE signals of nilotinib excavated in this study are consistent with the instructions. In clinical use,special attention should be paid to DME not mentioned in the instructions such as bone marrow failure,pulmonary hypertension and deafness; cardiac function, blood glucose and blood lipid indexes should be monitored closely.
RESUMO
Taking the Department of Pathology of Duke University as an example, this paper compares and analyzes the training mode of pathology residents in China and the United States. It is found that the organization and management system and supervision and assessment system of residency training in China have been improved, but it is still necessary to strengthen the in-depth implementation of humanistic education and training subjects for residents. Pathologist training should be based on "elite education" as the guiding ideology, to cultivate high-quality, high-level outstanding clinical pathology personnel as the specific goal, to build a solid foundation of clinical medicine.
RESUMO
OBJECTIVE To provide references for the clinical safe use of axitinib. METHODS Adverse drug event (ADE) data for axitinib were collected from the US FDA Adverse Event Reporting System (FAERS) database from the first quarter of 2012 to the fourth quarter of 2022. The data were mined and analyzed by utilizing the ratio-of-reporting-ratio (ROR) method and comprehensive standard method of the United Kingdom’s Medicines and Healthcare Products Regulatory Agency (MHRA) of proportional imbalance measurement. RESULTS A total of 13 962 reports of axitinib-related ADEs were obtained, with patients’ age concentrated in 65-85 years (43.25%), gender predominantly male (65.23%), country of reporting predominantly US (60.01%), and serious ADE outcomes mostly hospitalization or prolonged hospitalization (31.51%). A total of 172 ADE risk signals were detected, involving 18 system and organ classifications (SOC), mainly systemic diseases and various reactions at the site of administration (3 749 cases, 30.84%) and gastrointestinal system diseases (2 067 cases, 17.00%). ADE risk signals that occurred more frequently were generally consistent with the drug instruction, such as diarrhea, fatigue, and hypertension; new ADE risk signals requiring clinical attention were death, immune-mediated nephritis, and PT signals contained in the SOC of various benign, malignant, and tumors of undetermined nature (including cysts and polyps). CONCLUSIONS For ADEs that occur frequently with axitinib and are already contained in the drug instruction (e.g. hypertension, diarrhea), they should be adequately evaluated before administration, especially for patients with combined use of immune checkpoint inhibitors and patients with underlying hypertension; for ADEs with stronger signals and newer ADEs (e. g. death, disease progression, tumor progression), the patient’s disease progression should be closely monitored during the treatment period for potentially fatal ADEs; for its rare ADEs (e. g.immune-mediated nephritis, scrotal ulcer, non-infectious encephalitis), clinical validation should be further strengthened.
RESUMO
Sonodynamic therapy (SDT) is an emerging noninvasive treatment modality that utilizes low-frequency and low-intensity ultrasound (US) to trigger sensitizers to kill tumor cells with reactive oxygen species (ROS). Although SDT has attracted much attention for its properties including high tumor specificity and deep tissue penetration, its anticancer efficacy is still far from satisfactory. As a result, new strategies such as gas-assisted therapy have been proposed to further promote the effectiveness of SDT. In this review, the mechanisms of SDT and gas-assisted SDT are first summarized. Then, the applications of gas-assisted SDT for cancer therapy are introduced and categorized by gas types. Next, therapeutic systems for SDT that can realize real-time imaging are further presented. Finally, the challenges and perspectives of gas-assisted SDT for future clinical applications are discussed.

Measurements of the AV ?stula blood Conclusion ?ow in proximal artery and draining vein with its diameter of lumen were noted in the early postoperative period has a role predicting AV ?stula failure. There is risk of failure if the blood ?ow less than 182 ml/min (day 0–7)
RESUMO
India started Point of entry (PoE) surveillance at Mumbai International Airport, screening passengers returning from coronavirus disease (COVID?19)?affected countries using infrared thermometers. We evaluated in July 2020 for March 1–22 with the Centers for Disease Control and Prevention evaluation framework. We conducted key informant interviews, reviewed passenger self?reporting forms (SRFs) (randomly selected) and relevant Airport Health Organization and Integrated Disease Surveillance Programme (IDSP) records. Of screened 165,882 passengers, three suspects were detected and all were reverse transcription?polymerase chain reaction negative. Passengers under?quarantine line?listing not available in paper?based PoE system, eight written complaints: 6/8 SRF filling inconvenience, 3/8 no SRF filling inflight announcements, and standing in long queues for their submission. Outside staff deployed 128/150 (85.3%), and staff: passenger ratio was 1:300. IDSP reported 59 COVID?19 confirmed cases against zero detected at PoE. It was simple, timely, flexible, and useful in providing information to IDSP but missed cases at PoE and had poor stability. We recommended dedicated workforce and data integration with IDSP.
RESUMO
Background: High-risk pregnancy is defined as pregnancy complicated by factors that can adversely affect maternal and perinatal outcome. About 10–30% of pregnancies are high risk which accounts for 70–80% perinatal mortality and morbidity. Drug utilization data help to monitor the drugs prescribed and to assess the outcome by evaluating appropriateness and rationality of prescription. Aims and Objectives: This study aims to evaluate the pattern of drug use in high-risk pregnancy and to assess the WHO core prescribing indicator and US FDA category. Materials and Methods: A total of 250 case record forms of pregnant women admitted to high-risk ward were analyzed. Patient’s demographic data and detailed information about prescription were recorded and analyzed as per the WHO core drug prescribing indicators and US-FDA category. Descriptive statistics were used. Results: A total of 1121 drugs were prescribed among which antimicrobials (33.7%) were used more frequently followed by antihypertensive (13.9%), intravenous (609, 54.2%) route was the major route of drug administration, followed by oral (527, 47%), intramuscular (33, 2.9%), and subcutaneous (16, 1.4%). Average number of drugs per encounter was 4.48, percentage of encounters with an antimicrobials prescribed is around 70.4%, percentage of drugs prescribed by generic name was 93.5%, percentage of drugs prescribed from essential drugs list was 73.3%, and percentage of encounters with an injection prescribed was 50.4%. Majority of drugs belong to the US-FDA pregnancy Category B (45.04%), followed by Category C (39.4%), A (10.8%), and D (4.6%). Conclusion: Majority of drugs were prescribed by generic name and belonged to Category B drugs which are considered safe. Standards of prescription were in accordance with the WHO prescribing indicators. Overall prescribing behavior is rational and encouraging.
RESUMO
Background: Corn is, quantitatively, one of the most important world crops (ranking second only after wheat) and a key ingredient in animal feeds. Objective: to assess and compare corn quality, mycotoxin content, chemical composition and apparent metabolizable energy (AME) of domestic and imported corn. Methods: Grain quality (USDA grading system) was determined in 30 samples of domestic and 21 samples of imported corn. From each origin, 15 samples were subjected to proximal analysis and 10 were used to determine fatty acid composition. Mycotoxin analysis was conducted on 30 samples of domestic and 23 of imported corn. Results: six of the 30 domestic samples corresponded to US1 grade (highest quality) vs. none of the imported. In the "sample grade" category (lowest quality), 10 and 6 samples corresponded to imported and domestic corn, respectively. Soybeans were found as contaminant in 15 of the 21 imported corn samples. Aspergillus spp. mycotoxins such as ochratoxin A were not detected, and aflatoxins were found in only a few samples at very low levels. Fusariotoxins such as deoxynivalenol and zearalenone were found in 61 and 43% of imported samples, respectively, but in none of the domestic samples. Domestic corn had lower carbohydrate content compared with imported corn (85.4 vs. 86.7%), but higher crude fat (3.8 vs. 3.1%). The AME values for domestic and imported corn were 3,697 and 3,378 kcal/kg, respectively. The fatty acid profiles from both corn types were similar. Conclusion: This study found significant differences between locally-grown and imported corn, particularly in terms of crude fat, AME content, fusariotoxins, and contaminant seeds (soybeans). These findings suggest that locally-grown corn might have nutritional and toxicological advantages over corn imported from the United States.
Antecedentes: El maíz es, cuantitativamente, uno de los cultivos más importantes a nivel mundial (ocupa el segundo lugar después del trigo) y uno de los principales ingredientes en dietas para animales. Objetivo: Evaluar y comparar la calidad del maíz, su contenido de micotoxinas, composición química, y energía metabolizable aparente (AME) del maíz nacional e importado. Métodos: La calidad del grano (sistema de clasificación de la USDA) se determinó en 30 muestras de maíz producido en Colombia y 21 de maíz importado. De cada origen, 15 muestras se sometieron a análisis proximal y 10 se analizaron para determinar el perfil de ácidos grasos. El contenido de micotoxinas se determinó en 30 muestras de maíz nacional y 23 de maíz importado. Resultados: Seis de las treinta muestras nacionales analizadas para calidad de grano correspondieron a grado US1 (la mejor calidad) frente a ninguna de las importadas. En categoría "grado muestra" (la menor calidad) se encontraron 10 y 6 de las muestras de maíz importado y nacional, respectivamente; 15 de las 21 muestras de maíz importado presentaron contaminación con semillas de fríjol soya. No se encontraron micotoxinas de hongos Aspergillus spp. (ocratoxina A), y niveles muy bajos de aflatoxinas en unas pocas muestras. Fusariotoxinas tales como deoxinivalenol y zearalenona se detectaron en el 61 y 43% de las muestras de maíz importado, respectivamente, pero en ninguna muestra de maíz nacional. El maíz nacional presentó menor contenido de carbohidratos (85,4 vs. 86,7%), pero mayor contenido de grasa cruda (3,8 vs. 3,1%) en comparación con el importado, respectivamente. Los valores de AME fueron de 3.697 y 3.378 kcal/kg para el maíz nacional e importado, respectivamente. El perfil de ácidos grasos de ambas procedencias fue similar. Conclusiones: Este estudio encontró diferencias significativas entre el maíz de producción nacional y el importado, en especial en su contenido de grasa cruda y AME, fusariotoxinas, y semillas contaminates (soya). Estos hallazgos sugieren que el maíz de producción nacional puede presentar ventajas de tipo nutricional y toxicológico frente al maíz importado de los Estados Unidos de América.
Antecedentes: O milho é quantitativamente uma das culturas mais importantes em nível mundial (ocupando o segundo lugar depois do trigo), sendo um dos principais ingredientes em dietas para animais. Objetivo: Avaliar e comparar a qualidade do milho, o teor de micotoxinas, a composição química e a energia metabolizável aparente (EMA) do milho nacional e importado. Métodos: A qualidade do grão (sistema de classificação do USDA) foi determinada em 30 amostras de milho produzido na Colômbia e 21 amostras de milho importado. Quinze amostras de cada tipo de milho foram submetidas a análise proximal e dez amostras de cada milho foram analisadas para determinar o perfil de ácidos graxos. O conteúdo de micotoxinas foi determinado em 30 amostras de milho da Colômbia e em 23 amostras de milho importado. Resultados: Seis das trinta amostras colombianas analisadas para qualidade de grão corresponderam a grau US1 (melhor qualidade) frente a nenhuma das amostras importadas. Na categoria "grau amostra" (menor qualidade) foram encontradas 10 e 6 amostras de milhos importados e colombianos, respectivamente; Quinze das 21 amostras de milho importado apresentaram contaminação com sementes de feijão soja. Não foram encontradas micotoxinas de fungos Aspergillus spp. (ocratoxina A) ou apenas níveis muito baixos em poucas amostras (aflatoxinas). As fusariotoxinas, deoxinivalenol e zearalenona foram detectadas em 61 e 43% das amostras de milho importado, respectivamente, mas não foram detectadas em nenhuma amostra do milho colombiano. O milho colombiano apresentou menor conteúdo de carboidratos (85,4 vs. 86,7%) porém maior conteúdo de gordura crua (3,8 vs. 3,1%). Os valores de AME foram 3.697 e 3.378 kcal/kg para as amostras de milho colombiano e importado, respectivamente. O perfil de ácidos graxos de ambos tipos de milho foi similar. Conclusões: Os resultados do presente estudo mostram diferenças significativas entre o milho de origem colombiana e o milho importado dos Estados Unidos, em especial no conteúdo de gordura crua e AME, fusariotoxinas e sementes contaminantes (soja). Estes achados sugerem que o milho de produção colombiana pode apresentar vantagens de tipo nutricional e toxicológica frente ao milho importado dos Estados Unidos.
RESUMO
Resumen Antecedentes: La exploración articular por ultrasonido mediante el método HEAD-US en la detección de la artropatía temprana ha sido poco estudiada en nuestro país. Objetivo: Comparar la evaluación clínica y por ultrasonido de las articulaciones en niños con hemofilia. Métodos: Estudio longitudinal, prospectivo y descriptivo con pacientes pediátricos con hemofilia A y B valorados con la escala HJHS 2.1 y ultrasonido con transductor lineal de 8 a 12 MHz. Se evaluaron las articulaciones de codos, rodillas y tobillos de forma bilateral, con el método HEAD-US. Resultados: Se incluyeron 69 pacientes; de ellos, 48 con hemofilia A grave (peso: 40.1 kg). En la escala HJHS se observó mayor afectación en la rodilla izquierda (0.49) y menor en el tobillo derecho (0.05). Con la escala HEAD-US, la más afectada fue la rodilla derecha (0.78). Existe una relación significativa en la afectación de la rodilla derecha evaluada con la escala HEAD-US en presencia de inhibidor. Conclusiones: El peso superior al percentil 50 es un factor de riesgo independiente de complicaciones por sangrado articular, mientras que la edad y el tipo de hemofilia no parecen relacionados. El método HEAD-US es una herramienta útil y accesible para la detección temprana de artropatía y hemartrosis.
Abstract Background: Joint ultrasound examination using the HEAD-US method in the detection of early arthropathy is poorly studied in our country. Objective: To compare the clinical and ultrasound evaluation of the joints in haemophilia. Methods: Longitudinal, prospective and descriptive study with paediatric patients with haemophilia A and B evaluated with the HJHS 2.1 scale and ultrasound with a linear transducer of 8 to 12 MHz. Elbows, knees and ankles joints were evaluated bilaterally, with HEAD-US protocol. Results: 69 paediatric patients were included of which 48 with severe haemophilia A (weight: 40.1 kg). On the HJHS scale, a greater involvement was observed in the left knee (0.49), and less in the right ankle (0.05). With the HEAD-US scale, the most affected was the right knee (0.78). There is a significant relationship in the involvement of the right knee evaluated with the HEAD-US scale in the presence of inhibitor. Conclusions: Weight above the 50th percentile is an independent risk factor for joint bleeding complications, while age and type of haemophilia do not appear to be related. The HEAD-US method is a useful and accessible tool for early detection of arthropathy and hemarthrosis.

This article aimed to identify college/university students with elevated BMIs by campus type and region.@*METHODS@#Linear mixed effects regression models were fit to data from the American College Health Association-National College Health Assessment II. Analyses tested associations between campus type/region and student self-reported BMI.@*RESULTS@#The sample included 404,987 students from 445 schools with mean BMI 24.9 ± 5.8. Across all school types/regions, BMI confidence intervals included overweight values. Two-year and public school students had higher BMIs compared to four-year and private school students, respectively. Students in the Midwest had higher BMIs compared to students in the Northeast. In the South only, Minority Serving Institution (MSI) students had higher BMIs compared to non-MSI students.@*CONCLUSION@#Healthy weight maintenance programs should be made available to undergraduate students.

OBJECTIVE:To provide reference for clinical safe and rational drug use by mining adverse drug events (ADE) signals for tocilizumab. METHODS :Data of ADE reports related to tocilizumab in the first quarter of 2015 to second quarter of 2020 were collected from US FDA adverse event reporting system. After data standardization ,the proportional imbalance method was used for ADE signal mining. RESULTS :A total of 163 718 ADE reports were extracted ,in which tocilizumab was primary suspected drug ,involving 26 674 patients. In 26 674 patients,the proportion of female (73.69%)was higher than that of male (19.04%),and the age was mainly 60-74 years old (21.19%). Among the 163 718 ADE reports ,the main reporting countries were the United States (70.15%),Canada(15.95%),Japan(3.33%),Australia(3.05%)and Brazil (1.43%);consumers (31.35%)and doctors (24.94%)were the main reporting staff. A total of 747 ADE signals for tocilizumab were obtained , commonly rheumatoid arthritis ,joint pain and pain ;and the signals as the increase of disability assessment scale score ,the decrease of disability assessment scale score ,abnormal diastolic blood pressure and abnormal systolic blood pressure were strong. A total of 33 kinds of ADE signals were found ,which were not recorded in the instructions of tocilizumab ,and mainly abnormal laboratory indicators such as decreased oxygen saturation ,decreased blood pressure and abnormal heart rate. ADE mainly involved 27 system organs ,including musculoskeletal and connective tissue ,various reactions of systemic diseases and drug delivery site , various examinations. CONCLUSIONS :In addition to the ADE mentioned in the drug instructions ,when using tocilizumab in clinic,attention should also be paid close to blood oxygen saturation ,blood pressure ,blood routine indexes and other laboratory indicators,and intervention measures should be taken early when ADE occurs ,so as to ensure the safety and effectiveness of drug use.
RESUMO
Africa can be "left behind" after other advanced continents recover from the coronavirus disease 2019 (COVID-19) pandemic as reflected by the global pandemic of HIV/MDS.In this paper,we summarize potentially adaptable,effective and innovative strategies from China,Italy,and the U.S.The purpose is to help African countries with weaker healthcare systems better respond to the COVID-19 pandemic.China,being the first to report COVID-19 infection swiftly swung into anti-epidemic actions by the use of innovative risk communication and epidemic containment strategies.Italy and U.S.,the next rapidly hit countries after China,however,experienced sustained infections and deaths due to delayed and ineffective response.Many African countries responded poorly to the COVID-19 pandemic as evidenced by the limited capacity for public health surveillance,poor leadership,low education and socioeconomic status,among others.Experience from China,Italy and U.S.suggests that a better response to the COVID-19 pandemic in Mrica needs a strong public health leadership,proactive strategies,innovative risk communication about the pandemic,massive tests and isolation,and scaling-up community engagement.Lastly,African countries must collaborate with other countries to facilitate real-time information and experience exchange with other countries to avoid being left behind.
