OBJECTIVE To compare the effects of roxadustat and recombination human erythropoietin （rHuEPO） on coronary artery calcification in maintenance hemodialysis （MHD） patients. METHODS In retrospective analysis， MHD patients prescribed roxadustat in the Blood Purification Center of the First Affiliated Hospital of Chongqing Medical University from April 2019 to June 2021 were selected as the ROX group （56 patients）， and MHD patients prescribed rHuEPO during the same period were selected as the EPO group （60 patients）， and follow-up observation was conducted for 12 months. The differences in laboratory index， coronary artery calcification score （CACS）， and cardiac ultrasound parameters before and after treatment as well as the occurrence of cardiac and cerebrovascular adverse events during follow-up period were compared between the two groups. RESULTS There was no statistical difference in CACS between the two groups before and after treatment （P＞0.05）； but the difference of CACS in the ROX group was significantly lower than the EPO group （P＜0.05）. There was no statistically significant difference in cardiac ultrasound parameters and laboratory indexes between the two groups before and after treatment （P＜0.05）. The incidence of apoplexy and myocardial infarction in the ROX group was lower than that in the EPO group （P＜0.05）， and there was no statistically significant difference in the incidence of hospitalization due to heart failure between the two groups （P＞0.05）. CONCLUSIONS Compared with rHuEPO， roxadustat may have a positive effect on delaying coronary artery calcification in MHD patients and may be beneficial in reducing the incidence of myocardial infarction and apoplexy in MHD patients.

Effect of Tinnitus on Sleep Quality and Insomnia

Abstract Introduction Tinnitus is a conscious perception of a sound resulting from abnormal activity within the nervous system. A relevant percentage of tinnitus patients report symptoms severe enough to significantly affect quality of life, including sleep disorders. Objectives To analyze the sleep quality, insomnia, daytime sleepiness, and risk of obstructive sleep apnea (OSA) in participants with tinnitus. Methods The sample comprised 18 adults and older adults aged between 18 and 85 years old (mean age = 58.7 ± 17.5 years old), females and males, with complaint of continuous tinnitus for > 1 month. The instruments used were the Tinnitus Handicap Inventory (THI) questionnaire, the Insomnia Severity Index, the Pittsburgh Sleep Quality Index, the Epworth Sleepiness Scale, and the STOP-Bang questionnaire. Results By means of the THI questionnaire, the tinnitus severity degree reported by most participants was mild (27.8%) and moderate (27.8%), having a positive (r = 0.582) and significant (0.011) correlation to sleep quality, measured by means of the Pittsburgh questionnaire. There was a positive correlation between the Insomnia Severity Index and tinnitus handicap (r = 0.499; p = 0.035). A total of 72.2% of the participants self-assessed their sleep quality as poor, in addition to moderate insomnia (27.8%), although there is low risk of OSA (66.7%), without complaints of excessive daytime sleepiness (72.2%). Conclusion Subjects with tinnitus complaint self-rated their sleep quality as poor. Moreover, the higher the reported tinnitus handicap, the greater the symptoms of insomnia. There was no influence of tinnitus in relation to daytime sleepiness and no relationship between the severity of tinnitus and the risk of OSA.

Dual orexin receptor antagonists for the treatment of insomnia: systematic review and network meta-analysis / Antagonistas duais do receptor de orexina para o tratamento da insônia: revisão sistemática e metanálise em rede

Abstract Background Several randomized clinical trials (RCTs) have shown that dual orexin receptor antagonists (DORAs) are effective in the treatment of chronic insomnia. However, the superiority of one particular DORA over the others remains unclear. Objective To perform a network meta-analysis to evaluate the efficacy of different DORAs in patients with chronic insomnia. Methods The Medline, Embase, and Cochrane Central databases were searched for RCTs that compared DORA with placebo in patients ≥ 18 years of age with a diagnosis of insomnia disorder. We pooled outcomes for wake time after sleep onset (WASO), latency to persistent sleep (LPS), total sleep time (TST), and adverse events (AEs). Results We included 10 RCTs with 7,806 patients, 4,849 of whom received DORAs as the intervention. Overall, we found that DORAs were associated with the improvement of all analyzed efficacy outcomes. Concerning TST, an apparent dose-dependent pattern was noticed, with higherdoses relating to a longerTST. Lemborexant 10mg provided the largest reduction in WASO (at month 1) in minutes (standardized mean difference [SMD] = −25.40; 95% confidence interval [95%CI] = −40.02- −10.78), followed by suvorexant 20/15mg (SMD = −25.29; 95%CI = −36.42- −14.15), which also appeared to provide the largest decrease in long-term WASO (SMD = −23.70; 95%CI = −35.89- −11.51). The most frequent AEs were somnolence, nasopharyngitis, and headache, with rates of up to 14.8%. Conclusion Our results suggest that DORAs are associated with greater efficacy when compared with placebo in the treatment of insomnia, a complex 24-hour sleep disorder. Additionally, dosing might play an important role in the management of chronic insomnia.

Resumo Antecedentes Inúmeros ensaios clínicos randomizados (ECRs) têm demonstrado que os antagonistas duais do receptor de orexina (dual orexin receptor antagonists, DORAs, em inglês) são eficazes no tratamento da insônia. Contudo, restam dúvidas quanto à superioridade de um DORA com relação aos outros. Objetivo Realizar uma meta-análise em rede para avaliar a eficácia de diferentes DORAs em pacientes com insônia. Métodos Foram feitas buscas nas bases de dados Medline, Embase e Cochrane Central por ECRs que comparassem DORAs e placebo em pacientes ≥ 18 anos de idade com diagnóstico de insônia. Os seguintes desfechos foram selecionados: tempo desperto após o início do sono (wake time after sleep onset, WASO, em inglês), latência para o sono persistente (latency to persistent sleep, LPS, em inglês), tempo total de sono (total sleep time, TST, em inglês), e efeitos adversos (EAs). Resultados Incluímos 10 ensaios clínicos com 7,806 pacientes, 4,849 dos quais receberam DORAs como intervenção. Os DORAs foram associados à melhoria de todos os desfechos de eficácia analisados. Em relação ao TST, um aparente padrão de dependência da dose foi identificado, com doses maiores se associando a um maior TST. Lemborexant 10 mg proporcionou a maior redução em WASO (no primeiro mês) em minutos (diferença padronizada das médias [standardized mean difference, [SMD], em inglês) = −25.40; intervalo de confiança de 95% [IC95%] = −40.02- −10.78), seguido de suvorexant 20/15mg (SMD = −25.29; IC95% = −36.42- −14.15), o qual também proporcionou a maior diminuição em WASO no longo prazo (SMD = −23.70; IC95% = −35.89- −11.51). Os EAs mais frequentes foram sonolência, nasofaringite e cefaleia, com taxas de até 14.8%. Conclusão Nossos resultados sugerem que os DORAs estão associados a uma maior eficácia quando comparados com placebo no tratamento da insónia, um complexo transtorno do sono de 24 horas. Além disso, a dosagem pode desempenhar um papel importante no manejo da insónia crônica.

Traditional Chinese Medicine Syndromes and Influencing Factors of Protein Energy Wasting in Chronic Kidney Disease Patients Undergoing Maintenance Hemodialysis：a Cross-sectional Study / 中医杂志

ObjectiveTo investigate the distribution of traditional Chinese medicine （TCM） syndrome types and influencing factors of protein-energy wasting （PEW） in chronic kidney disease （CKD） undergoing maintenance hemodialysis （MHD）. MethodsAccording to diagnostic criteria， 164 patients with MHD were divided into PEW group and non-PEW group. The clinical data of all patients were collected， including general information such as gender， age， height and weight， disease characteristics such as course， cormobidity， and haemodialysis duration， laboratory indicators such as blood routine， liver function， renal function， electrolyte， blood lipid， grip strength， and the four examinations. Logistic regression analysis was used to find the influencing factors of PEW by taking the clinical indicators with significant differences between the two groups （P＜0.05） as the independent variables， diagnosis of PEW as the dependent variable， and normal values as the reference. ResultsOut of 164 patients with MHD， there were 96 （58.5%） cases in PEW group and 68 cases （41.5%） in non-PEW group. Compared to the non-PEW group，PEW group had increased age， ratios of bedrest， deep vein preservation， edema， and low grip strength， percentages of comorbidities type 2 diabetes， cardiovascular and cerebrovascular diseases，infections and anemia， and levels of alanine aminotransferase and permine amin aminotransferase， as well as decreased body mass index， self-care ratio，internal arteriovenous fistula， red blood cell count， hemoglobin， serum total protein， serum albumin levels （P＜0.05）. The PEW group had significantly higher frequency of poor appetite and digestion， abdominal distension， fear of cold and preference of warmth， weak breathing and fatigue， poor appetite， oliguria， nausea and vomiting than non-PEW group （P＜0.05）. The incidence of both yin and yang deficiency syndrome and damp-turbidity syndrome were significantly higher in the PEW group than the non-PEW group， while that of liver-kidney yin deficiency syndrome and stirring of wind syndrome were lower （P＜0.05）. Logistic regression analysis showed that low BMI （＜22 kg/m2）， inability to take care of oneself， low grip strength，low serum albumin （＜38 g/L）， infection， older age， fear of cold and cold limbs，and poor appetite were the risk factors of PEW in patients undergoing MHD （P＜0.05）. ConclusionThe root syndrome of MHD-PEW patients is both yin and yang deficiency， concurrent with damp-turbidity syndrome. Low BMI， low serum albumin， infection and older age may be the influencing factors of PEW in patients undergoing MHD.

Research status of insect infestation of Chinese medicinal materials during storage / 中国中药杂志

During the storage process, Chinese medicinal materials are susceptible to insect infestation due to their own nature and external storage factors. Infestation by insects can have varying impacts on the materials. In mild cases, it affects the appearance and reduces consumer purchasing power, while in severe cases, it affects the quality, reduces medicinal value, and introduces impurities such as insect bodies, excrement, and secretions, resulting in significant contamination of the medicinal materials. This study reviewed the rele-vant factors influencing insect infestation in Chinese medicinal materials and the compositional changes that occur after infestation and summarized maintenance measures for preventing insect infestation. Additionally, it provided an overview of detection techniques applicable to identifying insect infestation during the storage of Chinese medicinal materials. During the storage process, insect infestation is the result of the combined effects of biological factors(source, species, and population density of insects), intrinsic factors(moisture, chemical composition, and metabolism), and environmental factors(temperature, relative humidity, and oxygen content). After infestation, there are significant changes in the content of constituents in the medicinal materials. By implementing strict pre-storage inspections, regular maintenance after storage, and appropriate storage and maintenance methods, the occurrence of insect infestation can be reduced, and the preservation rate of Chinese medicinal materials can be improved. The storage and maintenance of Chinese medicinal materials are critical for ensuring their quality. Through scientifically standardized storage and strict adherence to operational management standards, the risk of insect infestation can be minimized, thus guaranteeing the quality of Chinese medicinal materials.

Maintenance therapy following allogeneic hematopoietic stem cell transplantation in myeloid neoplasms / 白血病·淋巴瘤

The acute myeloid leukemia and myelodysplastic syndromes are common myeloid neoplasms for which allogeneic hematopoietic stem cell transplantation is one of the main curative therapies. In high-risk patients, the relapse rate can be more than 40%, and patients with post-transplantation relapses have a very poor prognosis, so preventing relapse after transplantation is crucial. The maintenance therapy is a group of interventions to prevent relapse when morphological, molecular biological and cytogenetic results are constantly negative after transplantation. Currently, the commonly used maintenance therapy is the application of demethylating drugs, targeted drugs, etc., but their necessity, medicine plan, adverse effects, multi-drug combinations, and other aspects need to be studied urgently. This article will systematically describe the progress of post-transplantation maintenance therapy for high-risk myeloid neoplasms based on drug classification.

Advances of structure and mechanisms of bromodomain-containing protein 4 and its related research in tumors / 生物工程学报

The bromodomain and extraterminal domain (Bet) family are the regulators of the epigenome and also the pivotal driving factors for the expression of tumor related genes that tumor cells depend on for survival and proliferation. Bromodomain-containing protein 4 (Brd4) is a member of the Bet protein family. Generally, Brd4 identifies acetylated histones and binds to the promoter or enhancer region of target genes to initiate and maintain expression of tumor related genes. Brd4 is closely related to the regulation of multiple transcription factors and chromatin modification and is involved in DNA damage repair and maintenance of telomere function, thus maintaining the survival of tumor cells. This review summarizes the structure and function of Brd4 protein and the application of its inhibitors in tumor research.

Insomnia symptoms during the covid-19 pandemic: a case-control study / Sintomas de insônia durante a pandemia de covid-19: um estudo caso-controle

ABSTRACT OBJECTIVE To identify lifestyle-related, sociodemographic, and mental health characteristics of people with insomnia symptoms and people without insomnia during the pandemic. METHODS A case-control study was conducted with data collected by snowball sampling using an online questionnaire. From November 2020 to April 2021, 6,360 people with a mean age of 43.5 years (SD = 14.3) participated in the survey. For this study, we considered 158 cases of insomnia disorder and 476 controls (three controls per case) randomly selected from the participants without sleep problems. RESULTS The results of the comparative analysis between cases and controls showed that sleeping less than six hours daily (OR = 3.89; 95%CI 2.50-6.05), feeling sadness frequently (OR = 2.95; 95%CI 1.69-5.17), residing in metropolitan areas (OR = 1.71; 95%CI 1.04-2.84), being 40 years or older (OR = 1.93; 95%CI 1.22-3.06), and the interaction between occupation and poorer education (OR = 2.12; 95%CI 1.22-3.69) were predictors for symptoms of insomnia disorder during the pandemic. CONCLUSIONS In addition to confirming the hypothesis that mental health problems are associated with insomnia symptoms, the results point to insomnia as an important outcome for studies on the effects of unemployment, vulnerability and low education of the population, especially in large cities, highlighting that the effects of the crisis on health and the economy are extremely unequally distributed.

RESUMO OBJETIVO Identificar características relacionadas ao estilo de vida, sociodemográficas e saúde mental de pessoas com sintomas de insônia e pessoas sem insônia durante a pandemia. MÉTODOS A partir de dados coletados por amostragem em bola de neve, por meio de um questionário online foi realizado um estudo caso-controle. Durante o período de novembro de 2020 a abril de 2021, 6.360 pessoas com idade média de 43,5 anos (DP = 14,3) participaram da pesquisa. No presente estudo, foram considerados 158 casos de transtorno de insônia e 476 controles (três controles por caso) selecionados aleatoriamente dentre os participantes sem problemas de sono. RESULTADOS Os resultados da análise comparativa entre casos e controles mostraram que dormir menos de seis horas diárias (OR = 3,89; IC95% 2,50-6,05), sentir tristeza frequentemente (OR = 2,95; IC95% 1,69-5,17), residir em metrópoles (OR = 1,71; IC95% 1,04-2,84), estar com 40 anos ou mais (OR = 1,93; IC95% 1,22-3,06) e a interação entre ocupação e escolaridade mais precária (OR = 2,12; IC95% 1,22-3,69) foram fatores preditores para sintomas de transtorno de insônia durante a pandemia. CONCLUSÕES Além da confirmação da hipótese de que problemas de saúde mental estão associados a sintomas de insônia, os resultados apontam para a insônia como um desfecho importante para estudos sobre efeitos do desemprego, vulnerabilidade e baixa escolaridade da população, sobretudo nas grandes metrópoles, ressaltando que os efeitos da crise sobre a saúde e a economia são distribuídos de forma extremamente desiguais.

Prosthetic maintenance assessment for implant fixed complete dentures and implant overdentures: a randomized clinical trial / Avaliação da manutenção protética para próteses totais fixas suportadas por implantes e Overdentures: um ensaio clínico randomizado

Objective: The rehabilitation choice for the edentulous patients usually lies between the fixed and removable prosthetic options. The treatment decisions are affected by many factors where complications and maintenance needs are both considered crucial factors, in addition to the cost effectiveness of the chosen treatment. Material and Methods: This study was applied on 44 edentulous patients, where 22 patient for each group were enrolled in the outpatient clinic of prosthodontics, Cairo University as per a set of eligibility criteria. Four inter-foraminal implants were installed for all eligible participants. Three months later, healing abutments were used for soft tissue preparation prior to the fabrication of the final prosthesis. A prosthetic treatment option was then randomly allocated to obtain two equal groups via computer generated randomization program; Group. A received telescopic implant overdentures, and Group. B received screw retained dentures. All Complications (Screw loosening or fracture, tooth or denture base fracture and mucositis) were reported after overdenture insertion along the follow up period (1, 6, 9 and 12 months respectively). Results: The frequency of the screw loosening for hybrid overdentures where (59.1%) compared to (27.3%) of telescopic prosthesis at 12 months follow up period (p=0.035), mucositis reporting at 6m interval had shown the highest frequency in both groups (Group A (54.5%), Group B (81.8%), (p=0.045), all other reported complications that lack statistical significance either within the same group or between both groups at different time intervals. Conclusion: Both treatment modalities; telescopic implant overdenture and hybrid fixed screw-retained are reliable for restoring the completely edentulous arches, the decision whether to make a fixed or removable implant denture shall be guided with the patient preference together with the dentist assessment in relation (AU)

Objetivo: A escolha da reabilitação para pacientes edêntulos geralmente recai entre próteses fixas e removíveis. As decisões de tratamento são afetadas por muitos fatores onde as complicações e as necessidades de manutenção são consideradas critérios cruciais, além do custo-efetividade do tratamento escolhido. Material e Métodos: Este estudo foi aplicado em 44 pacientes edêntulos, onde 22 pacientes para cada grupo foram matriculados no ambulatório de prótese dentária da Universidade do Cairo de acordo com um conjunto de critérios de elegibilidade. Quatro implantes interforaminais foram instalados para todos os participantes elegíveis. Três meses depois, pilares de cicatrização foram utilizados para preparação dos tecidos moles antes da fabricação da prótese final. Uma opção de tratamento protético foi então alocada aleatoriamente para obter dois grupos iguais por meio de andomização gerada através programa de computador. O Grupo A recebeu overdentures de implantes telescópicos e o Grupo B recebeu dentaduras fixas parafusadas sobre os implantes. Todas as complicações (afrouxamento ou fratura do parafuso, fratura da base do dente ou da prótese e mucosite) foram relatadas após a inserção da overdentures ao longo do período de acompanhamento (1, 6, 9 e 12 meses, respectivamente). Resultados: A frequência do afrouxamento do parafuso para Overdentures híbridas (59,1%) em comparação com (27,3%) da prótese telescópica no período de acompanhamento de 12 meses (p=0,035), o relato de mucosite no intervalo de 6 meses mostrou a maior frequência em ambos os grupos (Grupo A (54,5%), Grupo B (81,8%), p=0,045, todas as outras complicações relatadas foram sem significância estatística dentro do mesmo grupo ou entre os dois grupos em intervalos de tempo diferentes. Conclusão: Ambas as modalidades de tratamento; overdentures sobre implantes telescópicos e próteses híbridas fixas parafusadas são confiáveis para reabilitar as arcadas completamente edêntulas. A decisão de fazer uma prótese fixa ou removível sobre implantes deve ser guiada pela preferência do paciente juntamente com a avaliação do dentista em relação ao estado geral do paciente e sua saúde bucal.

Prediction for recurrence following antithyroid drug therapy for Graves' hyperthyroidism

ABSTRACT Objective: A common problem with antithyroid drugs (ATD) treatment in patients with Graves' disease (GD) is the high recurrence rate after drug withdrawal. Identifying risk factors for recurrence is crucial in clinical practice. We hereby prospectively analyze risk factors for the recurrence of GD in patients treated with ATD in southern China. Subjects and methods: Patients who were newly diagnosed with GD and aged > 18 years were treated with ATD for 18 months and followed up for 1 year after ATD withdrawal. Recurrence of GD during follow-up was assessed. All data were analyzed by Cox regression with P values < 0.05 considered statistically significant. Results: A total of 127 Graves' hyperthyroidism patients were included. During an average follow-up of 25.7 (standard deviation = 8.7) months, 55 (43%) had a recurrence within 1 year after withdraw of anti-thyroid drugs. After adjustment for potential confounding factors, the significant association remained for the presence of insomnia (hazard ratio (HR) 2.94, 95% confidence interval (CI) 1.47-5.88), greater goiter size (HR 3.34, 95% CI 1.11-10.07), higher thyrotrophin receptor antibody (TRAb) titer (HR 2.66, 95% CI 1.12-6.31) and a higher maintenance dose of methimazole (MMI) (HR 2.14, 95% CI 1.14-4.00). Conclusions: Besides conventional risk factors (i.e., goiter size, TRAb and maintenance MMI dose) for recurrent GD after ATD withdraw, insomnia was associated with a 3-fold risk of recurrence. Further clinical trials investigating the beneficial effect of improving sleep quality on prognosis of GD are warranted.

Effects of aerobic exercise on body morphology in obese university students / Efeitos do exercício aeróbico na morfologia corporal de estudantes universitários obesos / Efectos del ejercicio aeróbico en la morfología corporal de estudiantes universitarios obesos

ABSTRACT Introduction The problem of obesity is relevant to the current social development model. In addition to the eminent physical health risks, obese university students also experience greater resistance to social development. Obese students participating in the national weight loss fitness program can perceive the benefits of aerobic exercise. Objective Explore the effect of aerobic exercise on body morphology in obese university students. Methods 60 obese university students were selected as study subjects and divided equally into a control and experimental group. The control group received no intervention, while the experimental group performed a battery of aerobic exercises of 60 minutes daily, four times a week for six weeks. Data before and after the experiment were compared. BMI, body fat rate, blood lipid monitoring, and blood glucose were also taken as body component monitoring indexes, and circumference measurements and proportions were taken as external body monitoring indexes. Results Aerobic exercise can effectively reduce the body weight, body mass index (BMI), body fat rate, and body circumference of college students, decrease body weight, make the body shape more symmetrical, and also improve lipid and glycemic components, thus reducing the complications caused by obesity. Conclusion University professors should perform aerobic training for university students to improve their physical fitness, regulate their physical function, and improve their physical appearance. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Impact of different sports on body mass of female university students / Impacto de distintos esportes sobre as massas corporais de universitárias / Impacto de diferentes deportes en la masa corporal de estudiantes universitarias

ABSTRACT Introduction A healthy body depends on several factors, and physical exercise is one of the main factors. Research results on the physical health of female university students show that although the general health status of Chinese female students is good, the quality of physical performance at university continues to show a slow downward trend. Objective To explore the effects of different exercises on the fat mass and lean weight indices of female university students. Methods 60 female students who participated in aerobics and ball games training in the Physical Education Department of a university were randomly divided into a control group and a training group, with 30 volunteers in each group. The experimental group performed intensive aerobics training and ball training. In contrast, no intervention was performed in the control group, and indicators were collected and analyzed according to current literature. Results After eight weeks of the intervention protocol, the body weight, body fat weight, lean weight, body surface area, and body fat ratio of the control group had no significant changes from the period before the experiment (P > 0.05). In the training group, fat weight decreased significantly (p<0.01), lean mass weight increased significantly (p<0.01), body fat ratio decreased (p<0.01), and body weight and body surface area had no significant changes (p>0.05). PTH and FSH in the training group were significantly higher than in the control group (P < 0.05). As the aerobic exercise level improved in the experimental group, the weight and abdominal skinfold thickness in the exercise group showed a downward trend. Conclusion There is a general correlation between BMI and body fat content and its body distribution in college women. Compared to men, BMI is better suited to describe the fat metabolism of college women. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Os resultados de pesquisa na saúde física das estudantes universitárias mostram que apesar do estado de saúde geral das estudantes chinesas serem bons, a qualidade no desempenho físico na universidade continua a mostrar uma lenta tendência de queda. Objetivo Explorar os efeitos de distintos exercícios sobre os índices de gordura e massa magra de universitárias. Métodos 60 alunas que participaram de treinamento de aeróbica e jogos de bola no Departamento de Educação Física de uma universidade foram divididas aleatoriamente em grupo de controle e grupo de treinamento, com 30 voluntárias em cada grupo. O grupo experimental realizou treinamento intensivo de aeróbica e treinamento com bola, enquanto nenhuma intervenção foi executada no grupo controle, a coleta e análise dos indicadores foi executada segundo a literatura corrente. Resultados Após 8 semanas do protocolo de intervenção, o peso corporal, peso da gordura corporal, peso magro, área de superfície corporal e relação de gordura corporal do grupo controle não tiveram alterações significativas em relação ao período anterior ao experimento (P > 0,05). No grupo de treinamento, o peso da gordura diminuiu significativamente (p<0,01), o peso da massa magra aumentou significativamente (p<0,01), a relação de gordura corporal diminuiu (p<0,01), o peso corporal e a superfície corporal não sofreram alterações significativas (p>0,05). O PTH e FSH no grupo de treinamento foram significativamente maiores do que os do grupo controle (P < 0,05). Com a melhora do nível de exercício aeróbico no grupo experimental, o peso e a espessura da dobra cutânea abdominal no grupo de exercício apresentaram uma tendência de queda. Conclusão Há uma correlação geral entre o IMC e o teor de gordura corporal e a sua distribuição corporal em universitárias. Em comparação com os homens, o IMC é mais adequado para descrever o metabolismo de gordura de universitárias. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.

Healthcare providers' satisfaction with participation in private health insurance scheme in a city in the southern Nigeria

Health insurance coverage in Nigeria is still very low as over 70% of health care expenditure is financed by out-of-pocket payment. Health care providers are critical participants in the private health insurance scheme, therefore, their perception and satisfaction with the scheme is fundamental in ensuring sustainability. This study assessed health providers' satisfaction with private health insurance scheme in Port Harcourt Rivers State.Method: A descriptive cross-sectional study which engaged a two-stage sampling method to recruit 60 participating health facilities and 180 responding health personnel by simple random sampling at each stage. A structured, pretested interviewer-administered questionnaire was used to collect data on the levels of satisfaction with the four major domains of satisfaction viz; billing rate, payment models, HMO administrative processes and claims management. Data was analysedusing of SPSS, version 26. Characteristics of the responding facilities were tabulated and compared. Level of satisfaction was deduced by Likert Scale according to the domains of satisfaction. Regression analysis with p-value was set at less than or equal to 0.05 was used to determine the predictors of satisfaction with participation in health insurance. The level of satisfaction with negotiated billing rates, payment models, HMO administrative processes and claims management were analyseddescriptively, and results were presented as means, standard deviation, frequencies and percentages, in tables, pie and bar charts
