RESUMO
A 68-year-old male patient with malignant left lung tumor was treated with gefitinib(250 mg,po,qd)for 29 days.Liver function test results showed AST 310 U·L-1,ALT 493 U·L-1,AKP 100 U·L-1,TBil 18 μmol·L-1,GGT 60 U·L-1,INR 1.81.Several liver function indicators of the patient showed abnormal,which was consistent with the clinical manifestations of moderate liver injury.The liver function index of the patient improved after the doctor adopted the suggestion of clinical pharmacists to protect the liver.Clinical pharmacists made a comprehensive and dynamic assessment of the patient's condition,analyzed the correlation between the patient's liver injury and gefitinib,and judged that the patient's liver injury was likely caused by gefitinib.Clinical pharmacists analyzed the drug use of a blind trial patient,proposed the follow-up treatment plan,and discussed the blind trial drugs,which provided references for clinical safe and rational drug use and had important reference significance.
RESUMO
Objective To analyze the changes of liver and kidney function, blood glucose and lipid metabolism at different follow-up time points of different treatment regimens, and to provide reference for clinical optimization and adjustment of medication in HIV/AIDS patients. Methods The changes of liver and kidney function, blood glucose and lipid metabolism at seven follow-up time points were analyzed retrospectively. The baseline blood collection time of HIV /AIDS patients was set as the starting point, and the final follow-up time was set as the end point. The seven follow-up points were 0, 3, 6, 9, 12, 18 and 24 months respectively. Results There were statistically significant differences in the distribution of sex, age, education, marital status, WHO staging, infection route, and baseline CD4+T lymphocyte count among 605 enrolled patients based on different treatment regimens. Liver function: The level of T-Bil in group E was higher than that of baseline at 9M, 12M, 18M and 24M after treatment (P<0.01); In group F, the level of T-Bil was higher than that of baseline at 9M after treatment (P=0.001); The levels of ALT in group C at the six follow-up points after treatment were higher than the baseline (P<0.001); The level of AST in group C was higher than that of baseline after 3M and 6M treatment (P<0.05). Renal function: The level of UREA in group C was higher than that in baseline after 6M treatment (P=0.007); The level of UREA in group F was higher than that in the baseline after 12M treatment (P<0.001); The level of UA in group F was higher than that of baseline after 3M, 6M and 12M treatment (P<0.05). Blood lipid and blood glucose: The levels of Glu at some follow-up points after ART treatment in group A and group C were higher than that at baseline (P<0.05); The levels of TG at some follow-up points in group A, group E and group F after ART treatment were higher than those at baseline (P<0.05); The levels of TC at some follow-up points in group A, group B, group C, group E and group F after ART treatment were all higher than the baseline (P<0.05). Conclusion Regular monitoring of changes in laboratory indicators of different treatment regimens during ART is of great importance to the prognosis of patients. Different laboratory indicators should be monitored according to different treatment regimens to effectively prevent adverse reactions caused by different treatment regimens.
RESUMO
Objective:To explore the relationship between drug resistance occurrence and the distribution pattern of polymorphic loci in individuals with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) treated with highly active anti-retroviral therapy (HAART).Methods:HAART-failed HIV/AIDS patients who successfully amplified the gene sequences of the pol region between June 2015 and December 2021 from 16 prefecture-level administrative regions in Yunnan Province were included.The resistant sequences were classified using the human immunodeficiency virus (HIV) basic local alignment search tool (BLAST) and validated through MEGA 6.0, and the obtained sequences were submitted to the Stanford University HIV Drug Resistance Database to identify drug resistance loci. The distribution of polymorphic loci was analyzed across patients exhibiting varying degrees of drug resistance, different treatment regimens and distinct HIV-1 subtypes.Changes of the frequencies of polymorphic loci in patients with different degrees of drug resistance were analyzed using trend chi-square test. Statistical comparisons and further paired comparisons were performed using chi-square test.Results:Gene sequences were amplified from 1 453 patients, and the resistance testing results showed 954 sensitive, 224 potentially or low resistant, 189 moderately resistant, and 86 highly resistant patients. The frequencies of mutations I15V, L19I, D60E in the HIV-1 protease region (PR region) and E36A, T39D, S48T mutations in the HIV-1 reverse transcriptase region (RT region) showed a decreasing trend as the degree of HIV-1 resistance escalated ( χ2trend=19.86, 9.16, 13.66, 37.64, 18.44 and 40.86, respectively, all P<0.01). Conversely, the mutations V77I in the PR region and K122E in the RT region showed an ascending trend ( χ2trend=12.19 and 10.03, respectively, both P<0.01). Distinct treatment groups, namely zidovudine (AZT)+ lamivudine (3TC)+ lopinavir/ritonavir (LPV/r), AZT+ 3TC+ efavirenz (EFV), AZT+ 3TC+ nevirapine (NVP), and tenofovir (TDF)+ 3TC+ EFV, were examined. Statistically significant differences in the frequencies of mutations E35D, M36I, and D60E in the PR region, as well as S48T, K122E, and R211K in the RT region, were observed among these treatment groups ( χ2=22.46, 9.32, 14.46, 26.85, 18.92 and 24.26, respectively, all P<0.05). In paired comparisons, AZT+ 3TC+ LPV/r group displayed higher frequencies of E35D, M36I, and D60E mutations, the AZT+ 3TC+ EFV group showed a higher frequency of S48T mutation, the AZT+ 3TC+ NVP group showed a higher frequency of K122E mutation, and the TDF+ 3TC+ EFV group exhibited a higher frequency of R211K mutation, all with statistically significant differences (all P<0.008). The differences in the frequencies of T12S, I15V, L19I, M36I, V77I, L89M in the PR region and E53D, I135V, S162C, R211K, K277R in the RT region among circulating recombinant form (CRF)08_BC, CRF07_BC and CRF01_AE subtype group were statistically significant ( χ2=693.60, 712.51, 798.11, 434.85, 386.91, 657.78, 932.58, 409.21, 344.39, 469.44 and 260.48, respectively, all P<0.001). In paired comparisons, the frequencies of T12S, I15V, L19I, E53D, I135V, S162C and R211K in CRF08_BC subtype, the frequencies of V77I and K277R in CRF07_BC subtype, and the frequencies of M36I and L89M in CRF01_AE subtype were higher than those in the other two groups, and the differences were all statistically significant (all P<0.017). Conclusions:The polymorphic loci resulting from HIV-1 HAART failure show different distribution patterns across various degrees of drug resistance, treatment regimens and HIV-1 subtypes.These loci demonstrate both specific and shared characteristics. It is necessary to enhance the surveillance of select polymorphic loci.
RESUMO
Objective:To study the clinical characteristics and differences of severe hyperbilirubinemia caused by hemolytic disease of the newborn (HDN) and glucose-6-phosphate dehydrogenase (G6PD) deficiency.Methods:From January 2014 to December 2021, newborns (gestational age ≥ 35 weeks and postnatal age ≤ 28 d) admitted to the Department of Neonatology of Hunan Children's Hospital with severe hyperbilirubinemia caused by HDN or G6PD deficiency were retrospectively analyzed. According to the etiology of hyperbilirubinemia, they were assigned into HDN group and G6PD deficiency group. The general conditions, clinical manifestations, laboratory results, treatment and prognosis of the two groups were compared using SPSS 26.0 software.Results:A total of 532 cases were in the HDN group and 413 cases in the G6PD deficiency group. The HDN group reached peak hyperbilirubinemia earlier than the G6PD deficiency group [3(2,5) d vs. 6(4,8)d, P<0.05]. The HDN group had lower peak value of total serum bilirubin [379.5(345.6,426.7) μmol/L vs. 486.4 (413.5,577.4) μmol/L] and lower incidence of anemia [37.4% (199/532) vs. 55.0% (227/413)]than the G6PD deficiency group.The incidence of anemia with elevated reticulocyte percent(Ret%) in the HDN group was higher than the G6PD deficiency group[66.3%(132/199) vs. 5.7%(13/227), P<0.05]. Compared with the G6PD deficiency group, the incidences of exchange transfusion and repeated (≥2 times) exchange transfusion, acute bilirubin encephalopathy(ABE) and the mortality rate after withdrawal of treatment in the HDN group were significantly lower ( P<0.05). Conclusions:Neonatal severe hyperbilirubinemia caused by HDN has early onset. G6PD deficiency caused hyperbilirubinemia has higher incidences of anemia, more severe jaundice and ABE, without increased Ret%.
RESUMO
Objective:To study the clinical features and treatment strategy of neonatal ureaplasma meningitis.Methods:During 2021, the clinical data of 2 neonates with ureaplasma meningitis treated in Children's Hospital of Hunan Province were retrospectively analyzed. Literature on this subject were searched in the following databases: CNKI, Wanfang Database, Chinese Medical Journal Full-Text Database, CQVIP database, SinoMed, PubMed, Embase and Web of Science (up to March 2022). The key words included “infant”, “neonate”, “newborn”, “ureaplasma”, “mycoplasma urealytium”, “meningitis”, “central nervous system infection”, “brain”. The clinical data, treatment and prognosis of patients from the literature were summarized.Results:Case 1, female, gestational age(GA) 33 +3 weeks, intracranial hemorrhage (ICH) and ventricular dilatation were found on 2 d after birth. The cerebrospinal fluid (CSF) routine and biochemistry tests indicated meningitis, but the CSF culture was negative. No improvement after antibiotic treatment. CSF metagenomic next-generation sequencing (mNGS) and 23S rRNA showed Ureaplasma urealyticum on 30 d after birth. The patient was treated with doxycycline (DOX) for 21 d until mNGS turned negative and DOX was discontinued. However, the disease recurred 23 d later and erythromycin was added with DOX as combined therapy. The patient was followed up until 6 months without neurodevelopmental disabilities. Case 2, male, GA 26 weeks, ICH and ventricular dilatation were found on 10 d after birth. The CSF routine and biochemistry tests indicated meningitis, but the CSF culture was negative. No improvement after antibiotic treatment. CSF mNGS and 23S rRNA showed Ureaplasma parvum. The patient received erythromycin therapy for 32 d and had normal neurodevelopment at 5 months. According to the literature, 43 cases were reported including the 2 cases descirbed above, 17 cases were full-term infants and 26 cases were preterm infants. The median CSF leukocytes, glucose and proteins were 566 cells/mm 3, 0.2 mmol/L and 2.2 g/L. 27 cases were diagnosed based on CSF culture, 6 cases using mNGS, 4 cases with both CSF culture and PCR method and 6 cases with other methods. Macrolides alone were used in 14 cases, macrolides combined with another antibiotic were used in 8 cases, non-macrolide antibiotics were used in 9 cases and 12 cases didn't receive any anti-ureaplasma therapy. All 17 term infants survived, however, 8 cases with hydrocephalus. Among the 26 preterm infants, 8 patients died, 18 patients had periventricular-intraventricular hemorrhage and 15 patients had hydrocephalus. Conclusions:Neonatal ureaplasma meningitis has significantly lower CSF glucose level with hydrocephalus as the common complication. For intracranial infections of unknown etiology and no response to treatment, mNGS is helpful in determining the pathogen.Neonatal ureaplasma meningitis should be treated with macrolides alone or as add-on therapy.
RESUMO
Objective:To evaluate the real-world short-term effectiveness of ixekizumab in the treatment of psoriasis, and to investigate factors influencing the effectiveness.Methods:Baseline data and short-term effectiveness evaluation results were retrospectively collected from patients with psoriasis, who received ixekizumab treatment in Department of Dermatology, Xiangya Hospital from November 2019 to September 2021. A descriptive analysis was performed on the baseline characteristics of patients, continuous data were described as median (lower quartile, upper quartile), and categorical data were described as percentages. Comparisons of disease severity scores before and after the treatment with ixekizumab were performed using Wilcoxon signed-rank test or paired McNemar test. Multivariable logistic regression analysis was conducted to explore factors influencing the effectiveness of 4-week ixekizumab treatment.Results:A total of 118 patients with psoriasis were included, including 94 males and 24 females, and their age [ M ( Q1, Q3) ] was 43.4 (32.5, 53.0) years; plaque psoriasis (99 cases, 83.9%) and severe psoriasis (72 cases, 68.6%) predominated among the 118 patients, and skin lesions were mainly located on the scalp (59/116, 50.9%). Among the 49 patients who had received 2-week ixekizumab treatment, 27 (55.1%) achieved a 50% improvement in the psoriasis area and severity index (PASI) score (PASI50) ; after 4-week treatment, 44 (89.8%), 30 (61.2%), 13 (26.5%) and 10 (20.4%) patients achieved PASI50/75/90/100 respectively, and their PASI scores (2.1 [1.1, 7.1]), involved body surface area (3.9% [0.5%, 14.5%]), dermatology life quality index scores (1.0 [0.0, 2.0]) and physician global assessment (PGA) scores (1.0 [1.0, 3.0]) were significantly lower than the corresponding scores at baseline (12.4 [8.8, 23.2], 22.0% [11.3%, 43.4%], 6.0 [3.0, 11.0], 4.0 [3.0, 5.0], respectively; all P < 0.001]. Multivariable logistic regression analysis showed that the baseline body mass index was significantly associated with the PASI75 response rate ( OR = 0.814, 95% CI: 0.659 - 0.958, P = 0.029) and the proportion of patients with PGA0/1 ( OR = 0.743, 95% CI: 0.562 - 0.917, P = 0.017) after 4-week ixekizumab treatment, and the baseline BSA score was significantly associated with the proportion of patients with PGA0/1 after 4-week ixekizumab treatment ( OR = 0.924, 95% CI: 0.870 - 0.968, P = 0.003) . Conclusion:The 4-week ixekizumab treatment significantly decreased the severity of psoriasis, and may be more effective in patients with lower disease severity and lower body mass index at baseline.
RESUMO
Objective:To investigate the molecular network of HIV-1 CRF01_AE in Yunnan Province and the factors influencing it.Methods:Demographic data and plasma samples of HIV/AIDS patients in Yunnan drug resistance monitoring database from 2018 to 2021 were collected. HIV-1 pol gene fragments (protease and reverse transcriptase region) were amplified using RT-PCR and then sequenced. The optimal gene distance was selected and a molecular network was constructed based on the sequences of CRF01_AE genotype. Results:In this study, a total of 967 sequences of CRF01_AE genotype were obtained by sequencing. At the optimal gene distance threshold of 1.75%, a total of 320 sequences were involved in the network with a rate of 33.1%, and 84 clusters were identified. In the regional distribution, one cluster dominated by multiple regions, one cluster dominated by Zhaotong, one cluster dominated by Honghe and five clusters dominated by Wenshan were formed in the network. In the network, 75.8% of heterosexual men were connected with other heterosexual men and 54.1% were connected with heterosexual women. There was potential transmission among 66.7% of men who have sex with men (MSM). HIV/AIDS patients in Chuxiong, Dali, Dehong, Honghe, Lincang, Pu′er, Wenshan, Yuxi and Zhaotong were more likely to be involved in the network that those in Kunming. People who were 50 years old and above were more likely to be involved in the network than those less than 25 years old. Factors influencing HIV/AIDS patients with HIV-1 CRF01_AE infection to become high-risk transmitters in Yunnan were not found and further study on this subject was needed.Conclusions:HIV-1 CRF01_AE strains had spread actively in different regions of Yunnan Province and the transmission network was complex. Dynamic monitoring of CRF01_AE strains should be strengthened and a precise intervention for high-risk transmitters should be performed to reduce new infections.
RESUMO
【Objective:】 To explore the relationship between the moral courage of nurses in Intensive Care Unit (ICU) and the hospital ethical climate, and to provide a theoretical basis for enhancing the moral courage of ICU nurses. 【Methods:】 A total of 468 ICU nurses from 8 tertiary A hospitals in Shaanxi Province were selected as the subjects by convenience sampling method, and the General Information Form, Hospital Ethical Climate Survey, and Nurses’ Moral Courage Scale were used for the questionnaire survey. 【Results:】 A total of 468 questionnaires were distributed and 463 valid questionnaires were returned, with an effective recovery rate of 98.93%. The score of hospital ethical climate for ICU nurses was (100.69±19.76), and the score of moral courage was (83.67±15.48). There was a positive correlation between hospital ethical climate and moral courage (r=0.866, P<0.001). Hierarchical multiple regression analysis showed that hospital ethical climate entered the influencing factor model of ICU nurses’ moral courage, which can independently explain 57% of the variation in ICU nurses’ moral courage. 【Conclusion:】 The moral courage of ICU nurses was at a medium level, and positively correlated with the hospital ethical climate, that is, the better the hospital ethical climate perceived by ICU nurses, the higher their level of moral courage. Nursing managers should focus on deepening the hospital ethical climate, and enhance the level of hospital ethical climate through scientific methods to promote the improvement of ICU nurses’ moral courage.
RESUMO
Objective:To analyze the variation characteristics of gag gene sequence of human immunodeficiency virus type 1 (HIV-1) epidemic strains in four major acquired immunodeficiency syndrome (AIDS) endemic areas in Yunnan Province. Methods:A total of 480 human immunodeficiency virus (HIV)/AIDS patients from designated antiviral treatment institutions in Kunming City, Dehong Dai and Jingpo Autonomous Prefecture, Hani-Yi Autonomous Prefecture of Honghe and Lincang City in Yunnan Province from January 2019 to December 2020 were randomly selected. The epidemiological information of the patients was collected. The plasma samples were collected and sent to the Yunnan Provincial Infectious Diseases Hospital for analysis. HIV-1 gag gene was amplified by nested polymerase chain reaction for genotyping.The phylogenetic tree was constructed by MEGA 6.06, and the characteristic amino acids were analyzed by VESPA online analysis tool. The gene distances of gag and matrix protein p17, capsid protein p24, nucleocapsid protein p7 and p6 protein of gag protein were calculated by Distance program. The ratio of synonymous mutation frequnency and non-synonymous mutation frequnency (Ks/Ka) was analyzed by SNAP program. Statistical comparison among multiple groups was performed using analysis of variance. Results:The gag gene sequences were successfully obtained from 404 patients.Most of these patients were men (250 cases, 61.9%), 59.7%(241/404) of patients were aged 40 to 59 years, and the main transmission route was heterosexual transmission (61.4%, 248/404). The main epidemic subtypes of HIV-1 were circulating recombinant form(CRF)08_BC (38.4%, 155/404), CRF01_AE (18.3%, 74/404), unique recombinant form (URF) (12.9%, 52/404), CRF07_BC(9.7%, 39/404), C subtype (8.4%, 34/404), other subtypes (6.9%, 28/404) and B subtype (5.4%, 22/404). Two main spreading clusters were formed by CRF08_BC in the phylogenetic tree, and there were significant differences in the distribution of characteristic amino acids of eight loci between the two spreading clusters, including No.79, 93, 121, 122, 151, 363, 395 and 396. The gag gene distances of CRF01_ AE, CRF07_ BC and CRF08_ BC were 0.090±0.004, 0.088±0.004 and 0.078±0.002, respectively, and the difference was statistically significant ( F=118.33, P<0.001). The Ks/Ka values of gag of the three subtypes were 4.003±1.309, 4.141±0.860 and 4.514±1.215, respectively, and the difference was statistically significant ( F=1.35, P<0.001). The Ks/Ka values of p17 were 2.590±0.186, 2.831±0.496 and 2.936±0.475, respectively, and the difference was statistically significant ( F=1.59, P<0.001). The Ks/Ka values of p24 were 12.579±1.116, 10.185±0.494 and 8.522±0.595, respectively, and the difference was statistically significant ( F=1.61, P<0.001). The Ks/Ka values of p7 were 10.850±0.711, 9.717±0.932 and 8.522±0.026, respectively, and the difference was statistically significant ( F=4.24, P<0.001). The Ks/Ka values of p6 were 3.122±0.134, 3.040±1.498 and 4.841±0.353, respectively, and the difference was statistically significant ( F=10.68, P<0.001). Conclusions:CRF08_ BC is the main subtype in these four areas in Yunnan Province.The different clusters of CRF08_BC result in a different pattern of amino acid composition.The variation degree of different subtype gag gene is different in each section. Surveillance of HIV variant strains should be strengthened to control the epidemics of HIV.
RESUMO
Circular RNA (circRNA), a novel type of covalently closed RNA, is implicated in several developmental and metabolic disease processes. CircRNAs exhibit tissue-specific expression, and are stable, abundant, and highly conserved, making them ideal biomarkers for diagnosis and prognosis. Accurate profiling of circRNA, however, is a prerequisite for their clinical application. Traditional methods such as northern blotting, RT-qPCR, and microarray analysis provide useful but limited information. To address these issues, a number of novel assays have recently emerged, such as droplet digital PCR (ddPCR), isothermal exponential amplification, and rolling cycle amplification, which increase the sensitivity and specificity of circRNA detection. Herein, we summarize the advantages and limitations of the new detection methods and discuss the challenges as well as future directions.

Understanding the relationship between air quality, pollution emission control measures, and meteorological conditions is important for developing effective air quality improvement policies. In this study, we used pollution monitoring and meteorological data from January to May 2020 to analyze the air quality characteristics during the COVID-19 lockdown in Wuhan, which lasted from January 23 to April 8, 2020. Compared with the same period in 2019, the air quality in 2020 was significantly better. The total excellent and good air quality rates increased by 17.58%-90.08% in 2020; concentrations of NO2, particulate matter with a diameter <10 µm (PM10) and <2.5 µm (PM2.5), and total volatile organic compounds (TVOCs) also decreased by 38.23%, 30.25%, 32.92%, and 39.80%, respectively. Moreover, the number of days with NO2, PM10, and PM2.5 as the primary pollutants decreased by approximately 10%, 9%, and 15%, respectively. We compared the wind direction, wind speed, temperature, and relative humidity in January-April 2020, 2019, 2018, and 2017 and found no obvious correlation between meteorological factors and improved air quality during the 2020 lockdown. The implementation of strict lockdown measures, such as home quarantining, traffic restrictions, and non-essential enterprise shutdowns, was the dominant cause for the substantial air quality improvement during the 2020 COVID-19 lockdown in Wuhan.

RESUMO
Objective To explore the feasibility of applying Omaha system theory to patients with coronary heart disease (CHD) through comparative analysis of nursing description. Methods Using content extraction analysis method, the nursing records, nursing plans and nursing measures of discharged patients with CHD were retrieved from the medical records, and then the conceptual consistency of the extracted records and the problem classification system and intervention measures in the Omaha system were evaluated by cross mapping method. Results A total of 2 609 nursing problems and intervention measures were extracted from the medical records of 68 patients with CHD. Among them, 1 844 (70.68%) records were labeled as "perfect fit", 608 records (23.30% ) as "partial fit", and 157 (6.02% ) recordsas"not fit at all". The total fit rate was 93.98% (perfect fit and partial fit). The most frequently reported problems were in physiological domain, followed by health-related behaviors domain, psychosocial domain and environmental domain. The nursing interventions extracted accounted for 26.67% (1 968 sentences) of directions and l00.00% (4 kinds) of categories in the intervention scheme of Omaha system. Conclusions The conceptual congruence between the medical records of patients with CHD and the Omaha System is quite high. It can help to improve nursing problems of patients of CHD in health-related behavioral domain, psychosocial domain and environmental domain, and can be applied to such patients after appropriate adjustment, so as to help clinical nursing staff to provide specialized and all-round guidance for patients with CHD.
RESUMO
Objective To analyze the genetic structure and recombination characteristics of a new-ly discovered HIV-1 unique recombinant strain in Yunnan Province. Methods During a test for drug-resist-ant HIV genotypes in Yunnan Province in 2016, a recombinant fragment was found in the pol region of a HIV-1 strain isolated from a patient. Two overlapping segments of the HIV-1 genome were amplified by RT-PCR, and then the products were sequenced. Recombination analysis was performed using RIP, jpHMM and SimPlot3. 5 software. A phylogenetic tree was constructed for homology analysis by Neighbor-joining method using MEGA6. 06 software. Results A nearly full-length HIV-1 gene sequence with 8590 bp in length was obtained. Breakpoint analysis indicated that the sequence consisted of CRF01_AE and fragments of B and C subtypes. CRF01_AE was used as the backbone with B and C subtype fragments inserted. The positions were 791 to 1171 for CRF01_AE, 1172 to 2652 for C subtype fragment, 2653 to 2977 for B subtype frag-ment, and 2978 to 9380 for CRF01_AE using HIV-1 HXB2 as the reference strain. Conclusions Some new strains formed by cross-recombination of CRF01_AE and B and C subtypes were discovered in Yunnan Province in recent years. It was found that the recombination pattern of the newly discovered strain was com-plex, suggesting that close attention should be paid to the changes in epidemic trends, which was of great im-portance to understand the current prevalence and epidemic trends of HIV-1.
RESUMO
Objective To investigate the influence factors of mortality among human immunodeficiency virus (HIV)-infected children under highly active antiretroviral therapy (HAART).Methods Retrospective cohort study of 652 children initiated HAART from 2005 to 2014 was conducted,and enrolled patients were followed-up until December,2015.Survival data was analyzed using Kaplan-Meier method and Cox regression model was used to identify independent predictors of mortality among these children on HARRT.Chi-square test and Fisher's exact test were used for comparison between groups.Results Overall,26 of the children died over a follow-up period of 3 116.24 child-years,with a mortality rate of 0.83 per 100 child-years.Twelve (46%)of deaths occurred during the first six months after starting HAART.Cox regression analysis of variables showed that the World Health Organization (WHO) clinical stages Ⅲ/Ⅳ (hazard rate [HR] =10.717,95%confidence interal [95% CI]:4.189-4.749,P =0.000),baseline hemoglobin < 80 g/L (HR =14.768,95 % CI:5.721-38.125,P =0.000),tuberculosis co-infection (HR =4.794,95% CI:2.105-10.918,P =0.000),baseline CD4+T lymphocyte < 50 cells/μL (HR =4.219,95% CI:1.524-11.680,P =0.006),weight-for-age z-score <-2 (HR =2.983,95 % CI:1.094-8.135,P =0.033) were independently associated with death,whereas the age < 7 year-old at HAART initiation was protectire (HR =0.293,95% CI:0.126-0.684,P =0.005).Conclusions The mortality of children receiving HAART is strongly associated with WHO stages Ⅲ/Ⅳ,hemoglobin < 80 g/L,weight-for-age z-score <-2,tuberculosis co-infection and older age at treatment.
RESUMO
PURPOSE: Numerous previous studies have reported inconsistent results about the differences between synchronous contralateral breast cancer (sCBC) and metachronous contralateral breast cancer (mCBC). This study aimed to compare the clinical characteristics and outcomes between sCBC and mCBC and determine predictive factors for the survival of sCBC and mCBC patients. METHODS: Using the Surveillance, Epidemiology, and End Results Program database, we identified sCBC or mCBC patients from 2000 to 2010. The Kaplan-Meier method and Cox proportional hazards regression analysis were used to analyze overall survival and breast cancer-specific survival (BCSS) rates of sCBCs and mCBCs, respectively. RESULTS: Overall, 14,057 sCBC (n = 8,139, 57.9%) and mCBC (n = 5,918, 42.1%) patients were included. The first tumors of sCBC were more likely to have higher stage and more lymph and distant metastases, whereas those of mCBC were more often infiltrating ductal carcinoma (IDC), had localized stage, were estrogen receptor (ER) and progesterone receptor (PR) negative, and had less axillary nodal involvement. The second tumors of mCBC tended to be IDC and have higher grade, adverse stage, ER and PR-negativity; and more axillary nodal involvement, compared to the second tumors of sCBC. mCBC patients had significantly favorable 5-year BCSS but worse long-term BCSS compared with sCBC patients. Moreover, subgroup analysis revealed no significant difference of BCSS between sCBC and mCBC among patients aged 18–60 years. Multivariate analysis indicated that age, grade, and stage of 2 tumors; surgery for second tumor; and ER status of the second tumor were independent prognostic factors for BCSS of contralateral breast cancer (CBC). CONCLUSION: The characteristics and outcomes of sCBCs and mCBCs were substantially different. sCBC and mCBC patients may have different prognosis, and the prognosis of CBC depends on the first and second tumors.

Objective@#To explore the feasibility of applying Omaha system theory to patients with coronary heart disease (CHD) through comparative analysis of nursing description.@*Methods@#Using content extraction analysis method, the nursing records, nursing plans and nursing measures of discharged patients with CHD were retrieved from the medical records, and then the conceptual consistency of the extracted records and the problem classification system and intervention measures in the Omaha system were evaluated by cross mapping method.@*Results@#A total of 2 609 nursing problems and intervention measures were extracted from the medical records of 68 patients with CHD. Among them, 1 844 (70.68%) records were labeled as "perfect fit", 608 records (23.30%) as "partial fit", and 157 (6.02%) recordsas "not fit at all". The total fit rate was 93.98% (perfect fit and partial fit). The most frequently reported problems were in physiological domain, followed by health-related behaviors domain, psychosocial domain and environmental domain. The nursing interventions extracted accounted for 26.67% (1 968 sentences) of directions and l00.00% (4 kinds) of categories in the intervention scheme of Omaha system.@*Conclusions@#The conceptual congruence between the medical records of patients with CHD and the Omaha System is quite high. It can help to improve nursing problems of patients of CHD in health-related behavioral domain, psychosocial domain and environmental domain, and can be applied to such patients after appropriate adjustment, so as to help clinical nursing staff to provide specialized and all-round guidance for patients with CHD.
RESUMO
Objective To analyze the molecular epidemiological characteristics of 38 HIV-1 positive seroconcordant couples in Yunnan Province. Methods The samples of HIV-1 antibody screened initially and positive confirmed in the Laboratory of Yunnan Provincial Infectious Diseases Specialist Hospital from 2014 to 2016 and laboratory data were collected. 41 samples from HIV-1 positive seroconcordant couples were selected and sequenced by RT-nested-PCR amplification. After the sequences were aligned and spliced, the qualified pol gene region sequence was used to construct phylogenetic tree and analyze subtypes, and the gene distance differences between each positive couple were calculated. Results A total of 76 pol gene regions from 38 HIV-1 positive seroconcordant couples were obtained. The major gene subtypes included CRF08_BC (45,59.2%), CRF07_BC (18,23.7%) and CRF01_AE (7,9.2%), there were also C (4, 5.3%) and B (2, 2.6%). Phylogenetic tree analysis and gene distance calculation clearly showed that HIV transmission between relationship partners occurred in 9 HIV-1 positive seroconcordant couples. Conclusions As the proportion of sexual transmission of HIV has risen year by year, the transmission between husband and wife should be the focus of our attention. Late diagnosis of HIV infection is the main factor that causes the transmission between husband and wife. For special populations, monitoring and testing should be strengthened as soon as possible, so as to reduce the occurrence of transmission between AIDS couples.
