Qualidade do acesso percebida por usuários de serviços especializados em HIV/AIDS da Bahia, Brasil / Quality of access perceived by users of HIV/AIDS specialized services in Bahia, Brazil / Calidad de acceso percibida por los usuarios de servicios especializados en VIH/SIDA en Bahía, Brasil

Este artigo descreve o acesso e a percepção do acesso de usuários a serviços especializados no tratamento do vírus da imunodeficiência humana e da Síndrome da Imunodeficiência Humana (HIV/AIDS) em municípios baianos por meio de um recorte epidemiológico descritivo-analítico, com abordagem quantitativa de dados primários de estudo realizado em cinco serviços localizados na capital e oito no interior do estado da Bahia, Brasil. Participaram deste estudo 475 usuários, de 21 municípios baianos, predominantemente do sexo feminino, com faixa etária entre 25 e 44 anos, negros, cristãos, desempregados, com escolaridade compreendendo o ensino fundamental, renda de até três salários mínimos, heterossexual e cisgênero. O acesso à testagem para HIV e outras Infecções Sexualmente Transmissíveis (IST), profilaxias de pós-exposição e pré-exposição e outros insumos de prevenção não constituíram motivação de inserção no serviço. O tratamento específico e a assistência médica para HIV e outras IST foi motivação para que a maioria dos participantes se direcionassem ao serviço especializado. O deslocamento até o serviço de referência é realizado principalmente por transportes coletivos, e o trajeto casa-serviço tem duração de pelo menos uma hora. O horário de funcionamento da unidade atende às necessidades da maior parte dos participantes, mas parcela dos usuários mencionaram o desejo de funcionamento em horários alternativos. A marcação de consultas é realizada principalmente de forma presencial e por telefone, com possibilidade de agendamento diário, assim a maioria dos usuários avaliaram a organização do serviço para marcação de consultas como boa ou muito boa. O tempo de espera, entre marcação e consulta, mais comum é de uma semana a um mês.

This article describes user access and perception of access to specialized HIV/AIDS services in Bahia municipalities by applying a qualitative epidemiological, descriptive-analytical approach to primary data from research conducted in five services located in the capital and eight in the countryside. A total of 475 users from 21 municipalities in Bahia participated in this study. Most were female, between 25 and 44 years old, Black, Christian, unemployed, with complete primary education, income of up to 3 minimum wages, heterosexual and cisgender. Access to HIV testing and other STIs, post-exposure and pre-exposure prophylaxis and other prevention inputs did not constitute motivation for procuring the service. Specific treatment and medical care for HIV and other STIs motivated most participants to turn to specialized services. Commuting to the reference service is made mainly by public transport and the home-service journey takes at least one hour. The unit's opening hours meet the needs of most participants, but some mentioned the desire for alternative operating times. Appointments are booked mainly in person and over the phone, with the possibility of daily scheduling, so most users rated the service organization for scheduling appointments as good or very good. The most common waiting time between booking and consultation is one week to one month.

'Uma parte de mim sabia que isso aconteceria um dia': vivências de jovens com HIV/aids / 'A part of me knew this would happen one day': experiences of young people with HIV/ AIDS

RESUMO O objetivo deste estudo foi compreender as representações sociais de jovens que vivem com o HIV. Estudo qualitativo, ancorado na Teoria das Representações Sociais, realizado com 16 jovens em acompanhamento ambulatorial. Os dados foram coletados entre maio e outubro de 2022, por meio de entrevista semiestruturada. Para o tratamento dos dados, empregou-se a técnica de análise lexical, operacionalizada com o auxílio do software Iramuteq. A representação fortemente associada ao diagnóstico de HIV está relacionada ao desconhecimento, preconceito e aceitação, apresentando, também, elementos positivos como recomeço. Classes: Diagnóstico positivo para o HIV: o 'eu' de agora; HIV em face do desconhecimento e do estigma; e Relações interpessoais: diálogo, acolhimento e respeito necessários aos jovens. Compreendeu-se que as representações sociais dos jovens com HIV refletem a sua condição na sociedade. Os dados deste estudo mostram que existem formas distintas de vivenciar o HIV, muitas vezes representadas pela fragilidade, pela resignação, e outras, pelo fortalecimento. A fim de minimizar a vulnerabilidade do jovem à exposição ao HIV e aos riscos de conviver com o estigma e preconceito social, fazem-se necessárias a adoção de estratégias de conscientização da sociedade sobre a doença e a ampliação da divulgação de políticas públicas que abarcam essa temática.

ABSTRACT This study was aimed at understanding the social representations of young people living with HIV. This is a qualitative study, based on the Social Representations Theory, carried out with 16 young people in outpatient follow-up. Data were collected between May and October 2022, through semi-structured interviews. For data processing, the lexical analysis technique was used, operationalized with the aid of the IRAMUTEQ software. The representation strongly associated with the diagnosis of HIV is related to lack of knowledge, prejudice and acceptance, also presenting positive elements such as a new beginning. Classes: Positive diagnosis for HIV: the new 'me'; HIV in the face of ignorance and stigma; and Interpersonal relationships: dialogue, acceptance and respect necessary for young people. It was understood that the social representations of young people with HIV reflect their condition in society. The data show that there are different ways of experiencing HIV, often represented by fragility, resignation, and other times by strengthening. In order to minimize the vulnerability of young people to exposure to HIV and the risks of living with stigma and social prejudice, it is necessary to adopt strategies to raise awareness about the disease and to expand the dissemination of public policies that cover this topic.

Introdução: A correção da relação radix dorso nasal é realizada há vários anos utilizando as mais variadas técnicas como enxerto de cartilagem auricular, septal ou costal, preenchimento com ácido hialurônico, uso de fáscia e enxertos e uso de cartilagem picada em cubo, silicone e ácido hialurônico. O uso de cartilagem fragmentada é descrito na literatura e tem ganhado adeptos nos últimos anos, pela facilidade em ser realizado. O objetivo neste estudo é descrever nossa experiência com a utilização do enxerto de cartilagem fragmentado no aumento do radix comparando a percepção visual e tátil do paciente e sua satisfação. Método: Estudo observacional em pacientes submetidos a rinoplastia no período de janeiro 2018 a junho de 2022, em cirurgias nas quais ocorreu o aumento de radix com o uso de enxerto de cartilagem picada. Resultados: Dos 47 pacientes, a maioria era do sexo feminino (35, 74,4%), com média de idade de 34,6 anos (18-44). Quanto ao tipo de pele, Fitzpatrick tipo 3 (n=28, 59,5%) foi o principal, sendo encontrado frequentemente pacientes com pele de média espessura (n=23, 48,9%). Complicações presentes foram infecção (1 caso), migração de cartilagem picada (3 casos), e reabsorção parcial (1 caso). Na avaliação da percepção tátil 42 pacientes (89,3%) percebiam, à palpação, as proeminências cartilaginosas e na visual apenas 2 (4%). A satisfação foi elevada em 45 (96%) pacientes. Conclusão: A cartilagem picada livre pode ser utilizada na região do radix com resultados satisfatórios.

Introduction: Correction of the nasal radix dorsum relationship has been carried out for several years using the most varied techniques such as auricular, septal, or costal cartilage grafts, filling with hyaluronic acid, use of fascia and grafts and the use of diced cartilage, silicone, and hyaluronic acid. The use of fragmented cartilage is described in the literature and has gained popularity in recent years, due to its ease of use. The objective of this study is to describe our experience with the use of fragmented cartilage graft in radix augmentation, comparing the patient's visual and tactile perception and satisfaction. Method: Observational study in patients undergoing rhinoplasty from January 2018 to June 2022, in surgeries in which the radix was increased with the use of minced cartilage graft. Results: Of the 47 patients, the majority were female (35, 74.4%), with a mean age of 34.6 years (18-44). As for skin type, Fitzpatrick type 3 (n=28, 59.5%) was the main one, with patients with medium-thickness skin being frequently found (n=23, 48.9%). Complications present were infection (1 case), migration of chopped cartilage (3 cases), and partial resorption (1 case). In the assessment of tactile perception, 42 patients (89.3%) perceived cartilaginous prominences on palpation and only 2 (4%) visually. Satisfaction was high in 45 (96%) patients. Conclusion: Free minced cartilage can be used in the radix region with satisfactory results.

Role of Supplementing Qi and Activating Blood in Preventing Relapse After Recovery of Community-acquired Pneumonia with Syndrome of Lung Deficiency and Collateral Stasis / 中国实验方剂学杂志

Community-acquired pneumonia （CAP） is a respiratory infection which takes a long time to fully recover after clinical symptoms are alleviated in the short term. It affects the physical health and quality of life of the patients in the long term and can occur repeatedly， which is related to inflammation， immunity， and the coagulation function. Lung Qi deficiency and collateral stasis are the key pathogenesis of CAP at the recovery stage. The development of CAP is accompanied by the decreased production and the increased consumption of Qi， which results in lung Qi deficiency. At the same time， heat pathogen forces the blood to move improperly， which depletes Qi and damages fluid， resulting in lung collateral stasis. Lung Qi deficiency and collateral stasis are causal and influence each other. The patients at the recovery stage of CAP generally present deficient lung Qi and healthy Qi， impaired immune function， and weakened defense function. However， pathogenic Qi， coagulation function changes， and thrombosis exist， and some coagulation factors are associated with the prognosis of CAP. The Chinese medicines for tonifying lung and supplementing Qi can help replenish healthy Qi， consolidate the body foundation， and regulate the inflammation. The Chinese medicines for activating blood and resolving stasis can dredge the lung collaterals， clear the pathogenic Qi， improve the microvascular circulation， and inhibit the inflammatory response. The Chinese medicines for supplementing Qi and activating blood can replenish healthy Qi and dispel pathogen to regulate immunity， inhibit inflammation， and alleviate the clinical symptoms， thus promoting the recovery from pneumonia. From lung Qi deficiency and collateral stasis， this paper summarizes the application and explains the scientific connotation of supplementing Qi and activating blood in preventing relapse after recovery of CAP， providing ideas for using this method to assist in preventing relapse after recovery of CAP.

Meta-analysis on failure mode and effect analysis for the prevention of ICU-acquired infection / 中国感染控制杂志

Objective To systematically evaluate the effectiveness of failure mode and effect analysis(FMEA)in the prevention of intensive care unit(ICU)-acquired infection.Methods Two researchers independently searched relevant literatures from foreign and Chinese databases,with a search deadline of July 15,2022.Independent screening of literatures,extraction of data and evaluation on overall quality were performed according to inclusion and exclusion criteria.RevMan 5.4 software was used to conduct Meta-analysis on the preventive effect of the in-cluded literatures.Results A total of 19 literatures were included in analysis.Meta-analysis results showed that ap-plication of FMEA method reduced the incidences of ventilator-associated pneumonia(OR=0.40,95％CI[0.31-0.51],P＜0.01),catheter-associated urinary tract infection(OR=0.29,95％CI[0.17-0.51],P＜0.01),cen-tral line-associated bloodstream infection(OR=0.28,95％CI[0.18-0.46],P＜0.01),and multidrug-resistant organism infection(OR=0.46,95％CI[0.37-0.58],P＜0.01)in ICU patients,as well as incidence of health-care-associated infection(HAI)in ICU(OR=0.46,95％CI[0.37-0.59],P＜0.01),and significantly improved the satisfaction of ICU patients and their families(OR=2.34,95％CI[1.72-3.17],P＜0.01).Conclusion FMEA can effectively prevent ICU-acquired infection and improve the quality of HAI management.

Clinical profile,imaging findings and endoscopic surgical treatment of acquired lacrimal sac mucocele / 中国内镜杂志

Objective To report the clinical features,imaging findings and endoscopic dacryocystosinostomy(En-DCR)of acquired lacrimal sac mucocele(ALSM).Methods 63 patients(63 eyes)with ALSM treated with En-DCR combined with bicanalicular silicone tube intubation from January 2016 to March 2021 were reviewed.The clinical features,imaging findings,and surgical treatment of the included patients were analyzed by preoperative examination and 12 month postoperative follow-up.Fifty-seven patients(21 males and 36 females)were enrolled in this study at last,including 30 right eyes and 27 left eyes,25～71 years old,with an average age of(52.89±11.66)years old.All eyes with history of epiphora and purulent secretion.Results CT examination revealed enlargement of the lacrimal sac,but no destruction of the adjacent bone.MRI imaging showed enlargement of the lacrimal sac,fluid collection separated from adjacent tissues by a thin rim,corresponding to mucocele in the sac and increase in the sac diameters in all analyzed cases.The mass was found to shrink significantly when the lacrimal sac was opened during the surgery,and the swelling was completely relieved within 7 days post-operation.After 12 months of follow-up,the anatomical success rate of En-DCR was 92.98%(53/57),the functional success rate was 89.47%(51/57),no complications such as mucocele recurrence,diminution of vision and infection were found.Conclusion All the patients with ALSM had a history of previous lacrimal duct obstruction.Imaging examinations are valuable for the diagnosis of ALSM.En-DCR for ALSM is safe and effective,and worthy of clinical promotion.

Functions of HIV-1 Tat and its association with diseases / 中国生物制品学杂志

@#Acquired immune deficiency syndrome,or AIDS,has been a major infectious disease that troubles the public health in a global scale. Human immunodeficiency virus type 1(HIV-1)is the causative reagent responsible for AIDS development. Even though the highly active anti-retroviral therapy(HAART,or the cocktail therapy)that has been widely applied could effectively suppress the infection and replication of HIV-1,the infected people suffer from other related diseases,such as the HIV-associated neurocognitive disorder(HAND). This paper mainly focused on the function of an important regulatory protein of HIV-1,trans-activator of transcription(Tat),and its correlation with HIV-1 replication and HAND development,so as to clarify the importance of developing anti-AIDS drugs targeting Tat protein

Knowledge and practices of nurses on the prevention and control of healthcare-acquired infections in a Private Tertiary Hospital in Baguio City

Background@#Healthcare-acquired infections (HAIs) are adverse events brought about by non-compliance of the healthcare staff to set of infection prevention and control (IPC) standards. Consequently, additional medical costs, increased mortality and morbidity rates, and decreased quality of life among patients can happen. As valuable players in preventing and controlling HAIs, nurses must have good knowledge and strict compliance with infection control; however, recent evidence suggests that nurses may need more knowledge or better integration into practice. Nurses' degree of knowledge and practice in preventing and controlling HAIs and factors influencing them should be determined to provide solutions appropriately.@*Objectives@#The study specifically sought answers to the following questions: (1) What is the level of knowledge of nurses in the prevention and control of HAIs? (2) What is the degree of practice of nurses in the prevention and control of HAIs? (3) Is there a significant relationship between nurses' knowledge level and degree of practice in the prevention and control of HAIs? (4) What are the facilitating and hindering factors that affect nurses' practice in the prevention and control of HAIs?@*Methods@#The study utilized a quantitative descriptive correlational design. The study was conducted from May to June 2023 at a private tertiary hospital in Baguio City. The study included 128 nurses who fit the inclusion criteria. The respondents were asked to answer three questionnaires, and the data were statistically treated using mean, Spearman Rank correlation, frequency, percentage, and rank distribution.@*Results@#The study found that nurses possess good knowledge and a suboptimal degree of practice in preventing and controlling HAIs. The results showed that no significant relationship existed between nurses' knowledge level and degree of practice in preventing and controlling HAIs. Perceived personal benefits and organizational encouragement were seen to primarily facilitate the prevention and control practices of nurses. The primary hindrance identified was workload due to staff shortage, poor dissemination of guidelines, and personal discomfort associated with the use of PPE.@*Conclusions@#A good level of knowledge is a derivative of learnings obtained through various educational modalities and these strategies are considered effective means of knowledge formulation. However, created knowledge without actual application into practice results in overuse of unhelpful interventions. To avoid the unnecessary effects of ineffective knowledge translation, a multifactorial consideration is necessary to identify other factors that may influence the practices of nurses on HAI prevention and control because knowledge does not solely improve or worsen actual practices. Identified facilitating factors should be supported, and hindering factors should be addressed. Further recommendations based on the study results include strengthening existing programs and policies, and developing accessible materials to improve the present practices of nurses.

Human immunodeficiency virus-associated Hodgkin lymphoma: a clinical analysis of 22 cases / 白血病·淋巴瘤

Objective:To investigate the clinical characteristics, therapeutic efficacy and prognosis of patients with human immunodeficiency virus (HIV)-associated Hodgkin lymphoma.Methods:A retrospective case series study was conducted. The clinical data of 22 HIV-associated Hodgkin lymphoma patients in Chongqing University Cancer Hospital from December 2013 to June 2022 were retrospectively analyzed. Their clinical features, laboratory results, treatment, and prognosis were analyzed. Kaplan-Meier method was used to perform survival analysis.Results:The age [ M ( Q1, Q3)] of 22 patients was 44 years old (36 years old, 53 years old); 18 cases were male, 4 cases were female; clinical staging was stage Ⅲ in 5 patients and stage Ⅱ in 17 patients. All 22 patients were infected with HIV through sexual transmission, with 10 cases transmitted through man sex with man and 12 cases transmitted through heterosexual transmission. Nine patients were found to be infected with HIV at the time of diagnosis of lymphoma, and 13 patients presented with lymphoma at 22.2 months (12.3 months, 38.4 months) after diagnosis of HIV infection. Of the 22 patients, 3 abandoned treatment; 19 patients were treated with antiretroviral therapy combined with ABVD regimen chemotherapy, 9 patients had complete remission, and 10 patients had partial remission. After follow-up of 46.8 months (24.8 months, 64.5 months), the 5-year progression-free survival rate was 83.9%, and the 5-year overall survival rate was 89.5%. Conclusions:HIV-associated Hodgkin lymphoma exhibits an invasive process in clinical practice, and standardized antiretroviral therapy combined with ABVD regimen chemotherapy can lead to long-term survival for patients.

Progress on risk factors involved in airway mucus hypersecretion in children with community acquired pneumonia / 国际儿科学杂志

Airway mucus hypersecretion is one of the pathological changes in children with community acquired pneumonia（CAP），and affects the severity，progression and prognosis of CAP.Diagnosis of airway mucus hypersecretion currently relies on fiberoptic bronchoscopy. To predict the risk of airway mucus hypersecretion and to take early action to avoid serious consequences such as plastic bronchitis and hypoxia and respiratory failure，the article summarizes the relationship between age，clinical characteristics and laboratory indices and the formation of airway mucus hypersecretion in children with CAP. Among them，age，pathogenic species，fever peak and fever range，neutrophil ratio，C-reactive protein，lactate dehydrogenase，D-dimer，serum 25（OH）D，and some interleukins，interferons，and acquired immune indicators have an early warning effect on the development of airway mucus hypersecretion in children with CAP.

Progress on the correlation between virus types and viral load and severity of viral pneumonia in children / 国际儿科学杂志

Community acquired pneumonia（CAP）is the leading cause of death in children，and as molecular diagnostic techniques continue to improve，more CAP is found to be caused by viral infections. At present，many factors are known to affect the severity of viral pneumonia，including viral subtypes，viral virulence，host factors，environmental factors，etc. Some studies have found that viral load is related to the severity of viral pneumonia，and different viral load levels have different effects on the severity of viral pneumonia. The correlation with virus type，subtype，site of virus specimen collection，age，sex and co-infection may be also different. This article will review the relationship between viral load and disease severity in pneumonia caused by common respiratory viral infections.

Effect of Elvitegravir,Cobicistat,Emtricitabine and Tenofovir Alafenamide single tablet alone and TDF+3TC+EFV scheme in the treatment of AIDS based on single blind prospective randomized trials / 国际检验医学杂志

Objective To investigate the effect of Elvitegravir,Cobicistat,Emtricitabine and Tenofovir Alafenamide single tablet alone versus tenofovir(TDF)+lamivudine(3TC)+efavirenz(EFV)scheme in the treatment of patients with acquired immunodeficiency syndrome(AIDS).Methods A total of 100 patients with AIDS who visited the hospital from January 2022 to October 2022 were selected and divided into two groups by random number table method,50 cases in each group.Group A was treated with Elvitegravir,Cobi-cistat,Emtricitabine and Tenofovir Alafenamide single tablet monotherapy and Group B was treated with TDF+3TC+EFV scheme.The human immunodeficiency virus(HIV)load,body immunity(CD4+,CD8+,CD4+CD38+cell ratio,CD8+CD38+cell ratio),lipid metabolism indexes[total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C)],glucose metabolism indexes[fasting blood glucose(FPG),glycated hemoglobin(HbA1c)],glycoprotein 130(gp130),interleukin-35(IL-35)and its receptor IL-12Rβ2 levels were observed before and after treatment in the two groups,and the drug safety in the two groups was counted.Results After 3 months of treatment,HIV load,CD8+count,CD4+CD38+cell ratio,and CD8+CD38+cell ratio in both groups were lower than those before treatment,and CD4+count was higher than that before treatment(P＜0.05),but the difference was not statistically significant when compared between A and B groups(P＞0.05).After 3 months of treat-ment,the levels of IL-12Rβ2,gp130,IL-35,TC,TG,and LDL-C in both groups were higher than those before treatment,and HDL-C level was lower than that before treatment,and the change in group B was greater than that in group A(P＜0.05).FPG and HbAlc levels were higher in group B after 1 month and 3 months of treatment,and were higher than those in group A(P＜0.05).Drug safety analysis showed that the incidence rates of adverse reactions were 12.00％(6/50)in group A and 26.00％(13/50)in group B,and there was no statistically significant difference between the two groups(P＞0.05).The incidence rates of liver and kidney injury in group A was 10.00％(5/50),and that in group B was 12.00％(6/50),and there was no statistically significant difference between two groups(P＞0.05).Conclusion Elvitegravir,Cobicistat,Emtricitabine and Tenofovir Alafenamide single tablet monotherapy and the TDF+3TC+EFV scheme could significantly re-duce the HIV load of AIDS patients and improve their immune level,but the former has less effect on pa-tients'glycolipid metabolism and inflammatory factors,and the monotherapy scheme is superior based on the comprehensive consideration of safety and efficacy.

Development and validation of a prediction model for severe community-acquired pneumonia in adults based on peripheral blood inflammatory indicators / 国际检验医学杂志

Objective To explore the development and validation of a prediction model for severe communi-ty-acquired pneumonia in adults based on peripheral blood inflammatory indicators.Methods Venous blood samples of 204 community-acquired pneumonia in adults patients admitted to 7 hospitals in Chongqing area from April 2021 to August 2022 were collected to detect C-reactive protein(CRP),peripheral white blood cell count(WBC),neutrophil to lymphocyte ratio(NLR),cytokines,lymphocyte subgroups and neutrophil CD64 index.All of patients were divided into a training group and a validation group according to the time of admis-sion.Univariate and multivariate Logistic regression were used to analyze the data of the training group,the characteristic factors of severe progression for pneumonia were selected to construct the nomogram model,and the data of the validation group was used to verify the model.The receiver operating characteristic(ROC)curve,calibration curve and decision curve analysis(DCA)were used to evaluate the prediction ability of the model for severe community-acquired pneumonia in adults.Results Logistic regression analysis showed that age,CRP,WBC,interleukin(IL)-4/interferon gamma ratio and IL-6/IL-10 ratio were independent risk factors for severe community-acquired pneumonia in adults.The area under the ROC curve of the nomogram model in the training group and the validation group was 0.893 and 0.880,respectively.The calibration curve and DCA results shown that the model had a good prediction effect for severe community-acquired pneumonia in adults.Conclusion The inflammatory indicators included in this model are simple and easy to obtain clinically.This model with good differentiation and accuracy,it can be used as a practical tool to predict severe community-ac-quired pneumonia in adults,and has certain clinical application value.

Objective To investigate the effect of early activity combined with electrical stimulation of neuromuscular system in improving intensive care unit(ICU)-acquired weakness(ICU-AW)patients with severe pneumonia.Methods A total of 150 patients with ICU-AW caused by severe pneumonia admitted to emergency intensive care unit(EICU)in a tertiary hospital in Shanghai were enrolled as the study subjects,and randomly divided into control group(75 cases)and combined group(75 cases).The control group took early exercise,and the combination group was given early exercise plus electrical stimulation of neuromuscular system.The recovery from mechanical ventilation(ICU length of stay,duration of mechanical ventilation,weaning extubation rate,ICU rollout rate),lung function[forced vital capacity(FVC),forced expiratory volume in the 1 s(FEV1)/FVC,massive inspiratory pressure(MIP)],muscle strength[Medical Research Council(MRC)score],disease severity[acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)],and complications were compared between the two groups.Results The ICU length of stay and mechanical ventilation time in the combined group were significantly lower than those in the control group(P<0.05).After intervention,FVC,FEV1/FVC,MIP and MRC scores in the two groups were significantly increased(P<0.05),and compared with the control group,the combined group was significantly increased(P<0.05).After intervention,APACHEⅡ score was significantly reduced in the two groups(P<0.05),and compared with the control group,APACHEⅡ score in combined group were significantly reduced(P<0.05).The complication rate in the combined group(9.33％)was significantly lower than that of control group(24.00％)(P<0.05).Conclusions Early exercise combined with neuromuscular electrical stimulation in patients with severe pneumonia ICU-AW can effec-tively promote recovery of patients because of improved lung function.This therapy is proved to be be safe and effective.

Analysis of Clinical Characteristics and Death Risk Factors in Patients with Community-acquired Pneumonia Complicated with Diabetes / 昆明医科大学学报

Objective To explore the clinical characteristics and risk factors of death during hospitalization in patients with community-acquired pneumonia(CAP)complicated with diabetes mellitus(DM).Methods A retrospective analysis was performed on 566 patients with CAP hospitalized in the Second Affiliated Hospital of Kunming Medical University from January 2018 to January 2022.The patients were divided into simple CAP group(n=478)and CAP combined with diabetes(CAP+DM)group(n=88)according to whether they had diabetes,and then CAP+DM group(n=88)was divided into survival group(n=69)and death group(n =19)according to whether the patients died during hospitalization.The clinical data and laboratory test indicators of patients in different groups were compared.Cox regression analysis was used to screen the risk factors of death during hospitalization in the CAP+DM group.Receiver operating characteristic(ROC)curve was plotted to evaluate the predictive value of independent risk factors on hospitalization death.Results Compared with the simple CAP group,the CAP+DM group had significant differences in age,concomitant hypertension,coronary heart disease,CURB-65 score,neutrophil to lymphocyte ratio(NLR),C-reactive protein(CRP),procalcitonin(PCT),albumin(ALB),prealbumin(PA),glucose(GLU),serum potassium(K),calcium(Ca),phosphorus(P),magnesium(Mg),lactic acid(Lac),non-invasive ventilation time,ICU occupancy rate and mortality rate(P<0.05);Compared with the survival group,there were statistically significant differences in CURB-65 score,NLR,CRP,PCT,GIU,ALB,PA,serum iron(Fe),Ca,non-invasive ventilation time,and ICU admission rate among the death group patients(P<0.05).Cox regression analysis showed that the increase of NLR level and the decrease in PA level were the risk factors for in-hospital death in patients with CAP complicated with diabetes(P<0.05).When the PA cutoff value was 91 mg/L,the AUC,sensitivity,and specificity for predicting in-hospital death of CAP patients with diabetes were 0.849,84.2%and 81.2%,respectively.Conclusion Patients with CAP combined with diabetes are more serious and have worse prognosis than those with CAP alone.PA has a good predictive value for the prognosis of these patients.Early detection and active intervention should be carried out to reduce the in-hospital mortality of patients.

Systematic evaluation of a predictive model for the risk of developing ICU-acquired dysphagia in critically ill patients / 中国实用护理杂志

Objective:To systematically evaluate the risk prediction model of ICU-acquired dysphagia in critically ill patients, and to provide a reference basis for medical practitioners to select or develop suitable risk assessment tools.Methods:Cross-sectional studies, case-control studies, and cohort studies of ICU-acquired dysphagia risk prediction models were searched in eight databases, including Wanfang database, China Biomedical Literature Database, VIP database, China National Knowledge Infrastructure, PubMed, Embase, CINAHL, and the Cochrane Library in both English and Chinese, and the search timeframe was from the construction of the database to July 5th, 2023. and the search was limited to Chinese and English. Literature was independently screened and data were extracted by 2 investigators, and the risk of bias assessment tool for predictive modeling studies was applied to analyze the risk of bias and applicability of the included literature.Results:A total of 8 high-quality papers were included, including 8 predictive models of risk of ICU-acquired dysphagia. The area under the subject operating characteristic curve for the models ranged from 0.750 to 0.980, with 6 models reporting calibration and 2 models having a Hosmer-Lemeshow test P>0.05, indicating good agreement. 2 models were externally validated. Independent predictors reported repeatedly for multivariate models were age ≥ 65 years, chronic lung disease, cerebrovascular disease, comorbid arrhythmias, use of sedative medications and duration of use, Acute Physiology and Chronic Health Evaluation Ⅱ score ≥ 15, presence of a nasogastric tube, duration of indwelling gastric tube ≥ 72 h, and duration of endotracheal intubation ≥ 72 h. Smaller sample sizes (outcome events), insufficient attention to missing data, variable screening processes irrationality, and model overfitting increased the risk of model bias. Conclusions:The included models showed overall good discrimination and applicability, but their risk of bias was high, and external validation was carried out in only a very few studies. Future studies should refer to transparent reports of multivariate predictive models to develop, update, and validate the models to obtain high-quality predictive models of the risk of ICU-acquired dysphagia, which can provide a reference basis for the development of relevant preventive strategies.

Correlation of platelet parameter changes and prognosis in children with severe community-acquired pneumonia / 中国小儿急救医学

Objective:To investigate the dynamic trend of platelet（PLT）count and mean platelet volume（MPV）in children with severe community-acquired pneumonia（SCAP）in PICU and their correlation with prognosis.Methods:A retrospective study was conducted in 215 SCAP children who were admitted to the PICU of Beijing Children's Hospital Affiliated to Capital Medical University from January 2016 to December 2019.According to the disease outcome，the patients were divided into improvement group ( n=184) and unrecovered group ( n=31).The changes of PLT count and MPV at admission，on the 2nd，3rd，and 7th days of hospitalization and before discharge were observed，and the relationship between changes in PLT parameters and poor prognosis was analyzed. Meanwhile，the correlation between thrombocytopenia on admission and on the 7th day of hospitalization and prognosis was further explored. Results:The PLT count of improvement group at admission，on the 2nd，3rd，and 7th days of hospitalization and at discharge[(328±159, 329±137, 362±159, 439±168, 510±171)×10 9/L] were significantly higher than those of unrecovered group [(210±142, 207±152, 267±143, 260±162, 343±159)×10 9/L]（ P＜0.05）.Although the MPV of improvement group [(10.9±1.9)fL] on admission was significantly lower than that of the unrecovered group[(12.7±2.5) fL]（ P＜0.05），there was no significant difference in MPV between two groups on the 2nd，3rd，7th days of hospitalization and discharge（ P＞0.05）.In addition，compared with the admission，children in improvement group had significantly higher PLT count on the 7th day of hospitalization and before discharge（ P＜0.05），but there was no significant change in unrecovered group（ P＞0.05）.Compared with SCAP patients with thrombocytopenia at admission (PLT＜100×10 9/L)( n=22),those with thrombocytopenia on 7th day of hospitalization had a significant higher rate of non recovery( P＜0.05). Conclusion:The occurrence of thrombocytopenia on admission and after 7 days of hospitalization in children with SCAP is associated with poor prognosis.No significant increase or decrease in PLT count after 7 days of hospitalization is often indicative of poor prognosis.Dynamic monitoring of PLT parameter changes may help to better judge the prognosis of severe pneumonia.
