On the Medical Justice View based on People’s Health / 中国医学伦理学

Medical justice is the concrete embodiment of social equity and justice in the field of medical care. The socialist system is a strong guarantee to solve the problem of medical justice. Basic medical service, which "guaranteed by the government, fairly obtained by all the people", is an inevitable requirement of socialist modernization with Chinese characteristics in the new era. The development of health and wellness in the new era should establish the core value concept of "taking people’s health as the center", take the "great health concept" as the guide, construct the medical justice concept based on people’s health, so as to provide a solid ideological guarantee for comprehensively promoting the construction of Healthy China, and then contribute to the Chinese model and Chinese scheme for global health governance. The main contents of medical justice based on people’s health should include fair medical treatment, accessible medical treatment and public welfare medical treatment. Its implementation path are: promoting the equalization of basic public medical services in urban and rural areas, continuously pressing forward the fairness of medical resource allocation; giving priority to people’s health and ensuring the justice of medical management system; coordinating the imbalance between doctors and patients effectively, and effectively promote the harmonious relationship between doctors and patients.

A Study Of The Impact Of Economic Status On The Opinion Of Beneficiary Candidates Of The Scheme Of Developing High Quality Research About The Scheme Benefits

Continuous improvement and evolution in various fields are crucial to ensure a better living environment for everyone. To achieve this, researchers have a significant responsibility to produce valuable research in concerned areas. However, dedicated researchers often face various obstacles, such as financial stress, which can hinder their ability to conduct research. To support Ph.D. scholars, many central and state government funding agencies offer financial assistance schemes. In this regard, the Government of Gujarat has initiated a scheme called SHODH – ScHeme Of Developing High quality research to provide financial support to Ph.D. scholars from recognized universities/institutes of the state to produce quality research in various disciplines. However, it is essential to understand the impact of the scheme's benefits from the perspective of the beneficiary candidates, especially those belonging to different economic statuses. Therefore, a study has been conducted to explore the opinions of beneficiary candidates of the SHODH scheme about the scheme's selected aspects and whether their opinions differ based on their economic status. The study adopts a causal-comparative research method to gain insight into the requirements of research scholars belonging to different economic statuses. This information will enable better facilitation of scholars to produce meaningful research in their respective fields.

Awareness, willingness, and challenges of the informal sector toward state National Health Insurance Services in Benin City, Nigeria

Background: As access to vital health services expands and universal health coverage is attained, health insurance is projected to serve as a critical risk protection for families and small enterprises. Aim: To assess the informal sector’s awareness, willingness, and problems in enrolling in the state national health insurance program. Materials and Methods: This cross-sectional descriptive study was done in Benin City, Nigeria, in the unorganized sector. A self-structured questionnaire was created, distributed, and retrieved for this study, which was conducted among 155 artisans chosen through a stratified random sample procedure. To evaluate the data, Statistical Package for the Social Sciences, SPSS version 22 was used. Results: In total, 138 people (89.0%) are aware of the National Health Insurance Scheme (NHIS), while only 93 people (60.0%) know that Edo state has a state-owned Health Insurance Scheme (SHIS). Only 17 people, or 11.0%, are engaged in the NHIS/SHIS program, whereas 107 people, or 77.5%, have expressed interest. Lack of accessibility to authorized healthcare facilities near house 22 (71.0%) is a significant deterrent to enrollment in the program. Long lines at service points (3.88, 1.093), the time it takes to enroll new members in the program (3.78, 1.101), the time it takes for health maintenance organizations to issue authorization codes (3.62, 1.316), the accessibility of NHIS services outside of registration institutions (3.29, 1.289), and the standard of drugs provided by the SHIS (3.12, 1.358) are all factors that hinder utilization. Sex and place of residence each strongly correlated with readiness to sign up for the program (AOR = 4.234, P = 0.017, 95% CI: 1.293–13.873 and AOR = 5.224, P = 0.007, 95% CI: 1.557–17.530, respectively). Conclusion: The artisans have a low rate of health insurance coverage but are eager to sign up for the program. State policymakers should increase their reach and make enrollment required to attain a higher range.

Introduction of Australian post-market reviews of pharmaceutical benefits scheme subsidized medicines and its implication to China / 中国药房

OBJECTIVE To provide a reference for strengthening the post-admission management of drugs on the medicare formulary in China. METHODS The basic situation， implementation process and effect of post-market reviews （PMR） were introduced after marketing approval of the Australian pharmaceutical benefits scheme （PBS） subsidized medicines. The suggestions were put forward for post-admission management of medicare formulary drugs in China. RESULTS & CONCLUSIONS PMR system exemplified Australia’s concept of life-cycle management of medicines on the PBS catalogue； as a mechanism for managing the admission and adjustment of PBS medicines， it provided a continuous evaluation of medicines in the PBS catalogue； the process mainly included two types： the pre-initiation process of PBS drug review and the PBS drug review process， involving steps such as drug selection， determination of review scope， and implementation management. Through PMR， Australia had completed the review of multiple medicines in nine treatment areas including diabetes， childhood asthma and Alzheimer’s disease in the PBS catalogue. The author suggests that China can improve the post-admission review of medicines at the institutional level （clarifying the selection criteria and methods of the review object， main procedures and responsible parties， and ensuring the transparency of the review process）； specify the National Healthcare Security Administration or the third-party organization until a special technical organization is established to take charge of this work； at the same time， further improve the construction of data collection and monitoring systems.

OBJECTIVE To mine the safety signals of FOLFOX scheme and FOLFIRI scheme-induced hepatotoxicity， and to provide reference for the selection of clinical rational treatment plan and the prevention and treatment of drug adverse reaction （ADR）. METHODS Reporting odds ratio method and proportion report ratio method were used to analyze adverse drug event （ADE） reports of FOLFOX scheme and FOLFIRI scheme in FDA adverse event reporting system during January 1， 2004-June 30， 2022. The potential safety signals of FOLFOX scheme and FOLFIRI scheme-induced hepatotoxicity were mined. RESULTS The amounts of ADE reports related to FOLFOX scheme and FOLFIRI scheme were respectively 3 454 and 1 359； the proportions of male and female patients involved were 1.50∶1 and 1.67∶1 in these two schemes， respectively. The top five countries with the largest number of reports were the United States， Japan， France， Italy and the United Kingdom， respectively accounting for 58.48% and 53.79% of the total reported cases. More than 90% of patients took no more than 5 drugs in combination， the proportion of patients receiving FOLFOX scheme and FOLFIRI scheme combined with anti-angiogenic drugs or epidermal growth factor receptor inhibitors was 45.45% and 86.82%， respectively. Totally 443 ADE reports of FOLFOX scheme-induced hepatotoxicity were collected， and 22 ADR signals were generated， including hepatic sinusoidal obstruction syndrome， nodular regenerative hyperplasia， drug-induced liver injury， blood bilirubin increased， etc. Totally 128 ADE reports of FOLFIRI scheme- induced hepatotoxicity were reported， and 9 ADR signals were generated， including blood bilirubin increased， hepatotoxicity， steatohepatitis， hepatic steatosis， etc. CONCLUSIONS FOLFOX scheme and FOLFIRI scheme can cause different types of hepatotoxicity. Clinical drug monitoring should be strengthened to guarantee drug safety.

Multi-level scoring approach to discover multi-targeting potency of medicinal plant phytochemicals against protein targets in SARS-CoV-2 and human ACE-2 receptor

SARS-CoV-2 pandemic has become a major threat to human healthcare and world economy. Due to the rapid spreading and deadly nature of infection, we are in a situation to develop quick therapeutics to combat SARS-CoV-2. In this study, we have adopted a multi-level scoring approach to identify multi-targeting potency of bioactive compounds in selected medicinal plants and compared its efficacy with two reference drugs, Nafamostat and Acalabrutinib which are under clinical trials to treat SARS-CoV-2. In particular, we employ molecular docking and implicit solvent free energy calculations (as implemented in the Molecular Mechanics -Generalized Born Surface Area approach) and QM fragmentation approach for validating the potency of bioactive compounds from the selected medicinal plants against four di?erent viral targets and one human receptor (Angiotensin-converting enzyme 2 -ACE-2) which facilitates the SARS-CoV-2entry into the cell. The protein targets considered for the study are viral 3CL main protease (3CLpro), papain-like protease (PLpro), RNA dependent RNA polymerase (RdRp), and viral spike protein-human hACE-2 complex (Spike:hACE2)including human protein target (hACE-2). Herein, thereliable multi-level scoring approach was used to validate the mechanism behind the multi-targeting potency of selected phytochemicals from medicinal plants. The present study evidenced that the phytochemicals Chebulagic acid, Stigmosterol, Repandusinic acid and Geranin exhibited efficient inhibitory activity against PLpro while Chebulagic acid was highly active against 3CLpro. Chebulagic acid andGeranin also showed excellent target specific activity against RdRp.Luteolin, Quercetin, Chrysoeriol and Repandusinic acid inhibited the interaction of viral spike protein with human ACE-2 receptor. Moreover Piperlonguminine and Piperine displayed significant inhibitory activity against human ACE-2 receptor. Therefore, the identified compounds namely Chebulagic acid, Geranin and Repandusinic acid can serve as potent multi-targeting phytomedicine for treating COVID-19

Enrollees’ knowledge, satisfaction, and barriers to uptake of National Health Insurance Scheme in north-central Nigeria

Background: Enrollees’ knowledge, behavior, and perception of health insurance substantially influence a decision about the uptake of sustainability of the program. This study assessed enrollees’ knowledge, satisfaction, and barriers to the National Health Insurance Scheme (NHIS) uptake in Benue State, Nigeria. Materials and Methods: The study was a descriptive survey conducted among hospital clients enrolled in the formal sector program of the health insurance scheme in Makurdi, Benue State, Nigeria. A structured questionnaire was used to collect respondents’ demographic information and data related to the knowledge, satisfaction, and barriers to the uptake of NHIS in Nigeria. IBM-SPSS version 25.0 was used to analyze the data. Results: The study comprised 53.2% males, and 46.8% were females. The majority (82.9%) of the enrollees were aware of the objectives of the NHIS, but only 33.4% were aware of their benefits as enrollees and only 56.0% were satisfied with NHIS services. Factors that significantly influenced enrollees’ satisfaction include sex, age, education level, income, and knowledge of enrollees’ entitlements (P < 0.05), but the family size and knowledge of the objectives of the NHIS were not significantly associated with the level of satisfaction (P > 0.05). The most common barriers to the uptake of the NHIS include cultural and religious norms (67.4%) and poor social infrastructures (60.6%). Conclusion: This study revealed that the enrollees had poor knowledge of their entitlements for enrolling in the NHIS and a low level of satisfaction. There is a need for more awareness interventions across Nigeria to sensitize citizens of the scheme’s importance, objectives, and benefits.

Objective:To investigate the efficacy and safety of BeEAM (bendamustine+cytarabine+etoposide+melphalan) regimen in pretreatment of autologous hematopoietic stem cell transplantation for patients with lymphoma.Methods:The clinical data of 15 patients with lymphoma who underwent autologous hematopoietic stem cell transplantation after pretreatment with BeEAM regimen from January 2020 to February 2021 in Gansu Provincial Hospital were retrospectively analyzed. The transplant-related adverse reactions and hematopoietic reconstitution were evaluated.Results:During the pretreatment process of 15 patients, 13 patients had gastrointestinal adverse reactions such as nausea, vomiting and diarrhea, 2 patients had hypokalemia, and 1 patient had abnormal liver function, but all of them were grade 1-2, and no grade 3-4 adverse reactions occurred. One patient had poor platelet implantation, and the remaining 14 patients all achieved hematopoietic reconstruction. After transplantation, the median time of peripheral blood neutrophils and platelets good implantation in patients was 10 d (9-14 d) and 11 d (9-17 d), respectively. Until March 2021, all patients were alive during follow-up.Conclusions:The efficacy of BeEAM regimen in pretreatment of autologous hematopoietic stem cell transplantation for patients with lymphoma is good, and the adverse reactions are tolerable.

Effect of different connection schemes of continuous renal replacement therapy and extracorporeal membrane oxygenation on arterial and venous pressure: an in vitro and in vivo study / 中华危重病急救医学

Objective:To investigate the effects of different connection schemes of continuous renal replacement therapy (CRRT) and extracorporeal membrane oxygenation (ECMO) on arterial pressure (PA), venous pressure (PV), and transmembrane pressure (TMP), and to provide a theoretical basis for choosing a suitable connection scheme.Methods:① In vitro study: the different connection schemes of CRRT and ECMO were simulated and divided into 6 schemes according to the connection between CRRT and ECMO circuits at different positions. Scheme A: connected to the front and back points of the oxygenator; scheme B: connected to the points behind and in front of the oxygenator; scheme C: connected to the points in front of the oxygenator and in front of the centrifugal pump; scheme D: connected to the points behind the oxygenator and in front of the centrifugal pump; scheme E: connected to the points in front of the oxygenator and the return catheter; scheme F: connected to the points after the oxygenator and the return catheter. Each set of ECMO circuits was measured 5 times under each connection scheme and different flow rates (2, 3, 4, 5, 5.5 L/min). Six ECMO circuits for a total of 30 measurements, and the PA, PV, and TMP of the 6 schemes were compared. ② In vivo study: the patients who were treated with ECMO combined with CRRT in the department of critical care medicine of the First Affiliated Hospital of Wannan Medical College from August 2017 to August 2021 changed the connection scheme due to high PA or PV (from scheme A or B to scheme E or F) were retrospectively analyzed. The changes of PA and PV before and after changing the scheme were compared. Results:① In vitro study results: there was no significant difference in PA between schemes A and B, C and D, E and F under different ECMO blood flow (2-5.5 L/min). The PA of schemes C and D was the lowest, followed by schemes E and F. PV of scheme B was higher than that of scheme A under different ECMO blood flow (2-5.5 L/min). There was no significant difference in PV between schemes C and D, E and F under high ECMO blood flow (3-5.5 L/min), and the absolute value of PV was lowest in schemes E and F. Compared with schemes A and B [partial PA > 300 mmHg (1 mmHg≈0.133 kPa) at high flow rate], C and D (partial PV > 350 mmHg at high flow rate), schemes E and F were more reasonable connection schemes. TMP was negative in schemes C and D at ECMO blood flow of 5 L/min and 5.5 L/min (mmHg; 5 L/min: scheme C was -29.14±11.42, scheme D was -42.45±15.70; 5.5 L/min: scheme C was -35.75±13.21, scheme D was -41.58±15.42), which indicated the presence of dialysate reverse filtration. Most of the differences in TMP among schemes A, B, E, and F under different ECMO blood flow (2-5.5 L/min) were statistically significant, and the absolute value of mean fluctuation was 9.89-49.55 mmHg, all within the normal range. ② In vivo study results: a total of 10 patients who changed the connection scheme (from scheme A or B to E or F) due to high PA or PV were enrolled, including 8 males and 2 females; 7 cases of venous-arterial ECMO (VA-ECMO) and 3 cases of venous-venous ECMO (VV-ECMO), all used continuous veno-venous hemodiafiltration (CVVHDF) mode. After changing the scheme, both PA and PV decreased significantly as compared with those before changing [PA (mmHg): 244.00±22.58 vs. 257.20±21.92, PV (mmHg): 257.20±18.43 vs. 326.40±15.41, both P < 0.01], and PV decreased more significantly than PA [difference (mmHg): 69.20±6.55 vs. 13.20±5.45, P < 0.01]. Conclusion:For patients treated with ECMO in combination with CRRT, the scheme of connecting the access line of CRRT to the pre-oxygenator or post-oxygenator and connecting the return line to the point of the return catheter can significantly reduce PA and PV and maintains normal CRRT operation even running high-flow ECMO.

Se diseñó un esquema de formación y desarrollo el cual se validó por aspecto, contenido y criterio. Resultados: Se destaca, según el esquema propuesto, la aparición de la cripta (etapa I) a los 9,0 años como intervalo medio (etapa I), así como el inicio de los movimientos eruptivos (etapa IV) a los 9,9, para dar paso al inicio de la formación de la raíz a los 10,3 (etapa V). La validez del contenido del esquema diseñado se logró con la opinión de los 15 expertos (6 estomatólogos con categoría de doctores en ciencias y 9 especialistas de Segundo Grado en Ortodoncia), la cual fue muy buena. Conclusiones: Fue posible validar el esquema de formación y desarrollo para los terceros molares, de modo que está disponible un instrumento válido y confiable, cuyo uso y adecuada aplicación se justifican en el ámbito investigativo(AU)

Introduction: Knowledge of dental development from its genesis to its appearance in the mouth is very useful for the dental clinical practice. Objective: To validate a training and development scheme for third molars. Material and Methods: An observational, descriptive, and cross-sectional study was carried out at "José Martí Pérez" Polyclinic from Santiago de Cuba in the period from May 2016 to February 2017. The universe consisted of 2 421 third molars, found in 618 panoramic radiographs of orthodontic patients 8 to 18 years of age. A training and development scheme was designed and validated by aspect, content and criteria. Results: According to the proposed scheme, the appearance of the crypt (stage I) at 9.0 years as a medium interval (stage I), as well as the onset of eruptive movements (stage IV) at 9.9 years, stand out to give way to the beginning of root formation at 10.3 (stage V). The content validity of the designed scheme was achieved by considering the opinion of 15 experts (6 dentists with Doctors of Science degree, and 9 second-degree specialists in Orthodontics), which was very good. Conclusions: It was possible to validate the training and development scheme for third molars, so a valid and reliable instrument, whose use and adequate application are justified in the research field, is available(AU)

Imunizações em pacientes com doenças raras ­ Posicionamento conjunto da Sociedade Brasileira de Imunizações (SBIm), Associação Brasileira de Alergia e Imunologia (ASBAI) e Sociedade Brasileira de Pediatria (SBP) / Immunizations in patients with rare diseases ­ A joint position statement of the Brazilian Society of Immunizations (SBIm), Brazilian Association of Allergy and Immunology (ASBAI), and Brazilian Society of Pediatrics (SBP)

Introdução: De acordo com a Organização Mundial da Saúde, a prevalência de doenças raras (abaixo de 65 casos/100.000 habitantes) é de 6%, e variável na dependência da população em estudo. Há 6.172 doenças raras (DR) catalogadas. Esquemas vacinais específicos para DR não estão disponíveis no Brasil, e esta orientação é limitada na maioria dos países. Objetivos: Identificar e propor esquemas específicos de imunização para pacientes com DR, tendo-se em conta segurança e eficácia. Fonte de dados: Revisão não sistemática da literatura, com busca de artigos de 2000 a 2020 no PubMed, Google Scholar, SciELO e Orphanet usando os termos "rare diseases" ou "inborn errors of metabolism" ou "cystic fibrosis" ou "inborn errors of immunity" e "vaccines" ou "immunization" ou "vaccination", nos idiomas inglês, francês, espanhol e português. Conclusões: A imunização de pessoas com DR é tema complexo, com poucas recomendações publicadas a este respeito, e na maioria das vezes realizada de modo empírico. É importante que a equipe médica que acompanha esses pacientes tenha um olhar abrangente e proporcione a prevenção mais completa possível.

Background: According to the World Health Organization, the prevalence of rare diseases (below 65 cases/100 000 population) is 6% and may vary depending on the study population. There are 6172 rare diseases (RD) listed. RD-specific vaccine schemes are not available in Brazil, and guidance is limited in most countries. Objectives: To identify and propose specific immunization schemes for RD patients, valuing safety and efficacy. Data source: A nonsystematic literature review was conducted, with search for articles from 2000 to 2020 on PubMed, Google Scholar, SciELO, and Orphanet with the terms "rare diseases" or "inborn errors of metabolism" or "cystic fibrosis" or "inborn errors of immunity" and "vaccines" or "immunization" or "vaccination," in English, French, Spanish, and Portuguese languages. Conclusions: Immunization of RD patients is a complex topic with few published recommendations, most often produced empirically. The medical teams following up these patients should have a more comprehensive insight and provide the most complete prevention possible.

Thinking and practice of key links in design of clinical trial scheme for treatment of influenza with traditional Chinese medicine / 中国中药杂志

To sort out the key points in "PICOS" design of clinical trial scheme for influenza, and optimize the clinical trial scheme of Chinese patent medicine in the treatment of influenza by strictly following the principle of evidence-based medicine, focusing on the clinical practice of the disease, and highlighting the characteristics of traditional Chinese medicine. "The design of a randomized, double-blind, positive parallel control study of a certain herbal preparation for the treatment of non-severe influenza" was taken as an example in this study, and the key points in the clinical trial design of Chinese patent medicine for the treatment of influenza were specifically discussed from six aspects, including the type of study, object of study, intervention measures, control measures, outcome indicators and frequently asked questions in test design. From methodological suggestions, in the design scheme of clinical trial on efficacy and safety of Chinese patent medicine in the treatment of influenza, the randomized controlled study should be the first choice for type of study; the inclusion criteria should define both the diagnostic criteria of Western medicine and the syndromes of traditional Chinese medicine(TCM); the exclusion criteria should include a comprehensive list of confounding factors and special circumstances lea-ding to bias in the study results; the interventions should be based on a well-defined dosing programme; internationally recognized positive drugs or guidelines should be used as control measures, with median antipyretic time as the main outcome indicator. For the evalua-tion of curative effect, disease symptom scale can be set, and the TCM syndrome scoring scale was carefully used in this study, with time nodes set for the efficacy evaluation standard. The full name of the drugs should be written in the regulations on combined drug use and prohibited drug use.

Blood component quality sampling: the use of characteristic curve scheme / 中国输血杂志

【Objective】 To explore the optimal sampling scheme for functional indexes of blood components, so as to ensure the accuracy of sampling. 【Methods】 The operation characteristic curves of 5 sampling schemes as (4, 1), (6, 1), (8, 2), (10, 2) and (12, 3) were drawn based on the characteristic curve theory of sampling inspection, the discriminability of those 5 sampling schemes was compared, and the risk of misjudgment and omission of sampling schemes was analyzed. 【Results】 The discriminability of 5 sampling schemes from high to low were (10, 2), (6, 1), (12, 3), (8, 2) and (4, 1), ; the operation characteristic curves of scheme (10, 2) were in basic concordance with (6, 1), (12, 3) and (8, 2) as the percent defective was <0.25. The risk of misjudgment of the 5 sampling schemes was low, and the risk of omission was high in scheme (4, 1)(0.738, 3), and low in (10, 2) and (6, 1) (0.525 6 and 0.533 9, respectively). 【Conclusion】 On the premise of strictly controlling the process of blood collection and supply and ensuring the quality of blood preparations, the sampling scheme (4, 1) can effectively monitor the stability of the whole process. However, for blood preparations with high nonconforming rate, sampling scheme (6, 1) or (10, 2) was recommended as the sampling amount should be elevated appropriately.
