Clinical application value of a predictive model for the efficacy of third-generation cephalosporin in treatment of community-acquired spontaneous bacterial peritonitis / 临床肝胆病杂志

ObjectiveTo investigate the clinical application value of a predictive model for the efficacy of third-generation cephalosporin in the treatment of community-acquired spontaneous bacterial peritonitis （CASBP）. MethodsThis prospective study was conducted among 50 patients with liver cirrhosis and CASBP who were admitted to The Ninth Hospital of Nanchang from January 2021 to June 2022， and the patients were randomly divided into optimized treatment group and traditional treatment group， with 25 patients in each group. The patients in the optimized treatment group received ceftazidime or imipenem for initial treatment based on the above predictive model， and those in the traditional treatment group received ceftazidime for initial treatment， with the subsequent use of antibiotics adjusted based on the efficacy of initial treatment. The two groups were compared in terms of the response rate of initial treatment， cure rate on day 5， and 30-day mortality rate. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsAll patients completed the study. The optimized treatment group had a significantly higher response rate of initial treatment than the traditional treatment group （88.0% vs 60.0%， χ2=5.094， P=0.024）， while there was no significant difference in the cure rate on day 5 between the two groups （80.0% vs 56.6%， χ2=3.309， P=0.069）. As for the patients who received ceftazidime for initial treatment， the optimized treatment group had a significantly higher response rate of initial treatment than the traditional treatment group （88.9% vs 60.0%， χ2=4.341， P=0.037）， while there was no significant difference in the cure rate on day 5 between the two groups （83.3% vs 56.0%， χ2=2.425， P=0.119）. There was no significant difference in 30-day mortality rate between the two groups （8.0% vs 20.0%， χ2=0.664， P=0.415）. For all patients， there was a significant association between response of initial treatment and cure on day 5 （odds ratio ［OR］=9.643， 95% confidence interval ［CI］： 2.292‍ — ‍40.564） and between cure on day 5 and 30-day mortality （OR=0.138， 95%CI： 0.023‍ — ‍0.813）. ConclusionThis predictive model for efficacy helps clinicians to identify the patients who can benefit from third-generation cephalosporin treatment and improve the efficacy of third-generation cephalosporin in the initial empirical treatment of CASBP.

Changes of HIV knowledge and attitude among students in Beijing from 2018 to 2022 / 中国学校卫生

Objective@#To explore the change of HIV knowledge, information access and attitude among college students in Beijing from 2018 to 2022, so as to provide reference for the formulation of targeted comprehensive prevention and control mesures for AIDS.@*Methods@#A stratified cluster random sampling method was used to select 3 098 undergraduate students in Beijing from January 2018 to December 2022, and a questionnaire was used to understand knowledge of HIV/AIDS among participants, information access and the attitude towards AIDS patients.@*Results@#The questionnaire showed that the awareness rate of college students who were correct in more than 8 questions regarding HIV/AIDS related knowledge showed an increasing trend from 2018 to 2022, which were 66.93%, 70.10%, 72.14%, 75.04% and 76.89%, respectively ( P <0.05). In the 5-year survey, the awareness rate of "sharing toothbrush, razor or acupuncture apparatus with others can be infected with AIDS" was the highest, accounting for 82.67%, 83.01%, 84.06%, 84.99%, 87.16%, respectively, and the difference was not statistically significant ( χ 2=6.14, P >0.05). The awareness rate of "using new drugs will increase the risk of HIV infection" was the lowest, accounting for 50.08%, 50.98%, 52.98 %, 54.00% and 59.23%, and the difference was statistically significant ( χ 2=12.87, P <0.05). From 2018 to 2022, the main access to HIV/AIDS information were the Internet, AIDS publicity materials, and family and friends notification. The acquisition of HIV/AIDS knowledge through the Internet showed an increasing trend by year, accounting for 77.90%, 80.88%, 82.13%, 83.03 % and 86.04%, respectively, with statistical significance ( χ 2 trend =14.37, P <0.05). Items of "choosing to gradually distance themselves after knowing that their friends around them are AIDS patients" "accepting to shake hands with AIDS patients", and "supporting and restricting activities of AIDS patients in public places" accounted for a relatively high proportion. During the year of 2018-2022, the diffences were not statistically significant ( χ 2=7.95, 2.45, 2.17, P >0.05).@*Conclusions@#HIV/AIDS knowledge among college students in Beijing from 2018 to 2022 needs to be improved. The Internet is the main way for college students to obtain HIV/AIDS knowledge. HIV/AIDS related discrimination is high among participants. Comprehensive HIV related knowledge education should be implemented to change the attitude of college students in Beijing.

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

Seasonal and epidemiological characteristics of community-acquired pneumonia in Chuzhou in 2010 - 2022 / 公共卫生与预防医学

Objective To analyze the seasonal and epidemiological characteristics of community-acquired pneumonia (CAP) in Chuzhou from 2010 to 2022. Methods The epidemiological data of CAP in Chuzhou from 2010 to 2022 were obtained from the center for diseases control and prevention of Chuzhou City, Anhui Province. After inclusion and exclusion, a total of 1 053 cases were enrolled. General data were collected. Then the characteristics of CAP patients in terms of gender, age, regional and seasonal distribution and pathogenic bacteria distribution were analyzed. Results A total of 316 patients with CAP, with a prevalence rate of 30.01%, including 152 males (48.10%) and 164 females (51.90%). Regarding age, 86 cases (27.22%) at 19-40 years, 106 cases (33.54%) at 41-60 years, and 124 cases (39.24%) at >60 years, suggesting a statistical difference in the CAP detection rate among different genders and ages (P<0.05). Seasonally, 118 cases (37.34%) were detected in spring, 13 cases (4.11%) in summer, 49 cases (15.51%) in autumn, and 136 cases (43.04%) in winter, with the highest CAP detection rate in winter, followed by spring. Pathogenic bacteria were positive in 198 of 316 patients, with a detection rate of 62.66%. A total of 125 strains of pathogenic bacteria were detected in sputum culture, of which 138 cases were Gram-negative, mainly Escherichia coli (24.24%, 48/198), and 60 cases were Gram-positive, mainly Streptococcus pneumoniae (14.14%, 28/198). Among 198 patients positive for pathogen detection, 41 cases were detected in spring, 37 cases in summer, 56 cases in autumn and 64 cases in winter. The drug sensitivity results showed that Escherichia coli had the highest resistance rate to ampicillin and cefazolin, and was sensitive to imipenem and other antibiotics; Streptococcus pneumoniae has the highest resistance rate to penicillin and erythromycin, and is sensitive to vancomycin. Conclusion CAP is quite common in elderly population in Chuzhou from 2010 to 2022, with a high prevalence rate in spring and winter, and the prevention work of high-risk groups should be strengthened.

Research progress on immunomodulatory properties of periodontal ligament stem cells / 口腔疾病防治

@#Periodontal ligament stem cells (PDLSCs) have the potential for multidirectional differentiation and are the preferred seed cells for periodontal tissue regeneration. In recent years, a large number of studies have confirmed that PDLSCs also possess broad immunomodulatory properties. Therefore, in-depth exploration of their specific molecular mechanisms is of great significance for the treatment of periodontitis. The aim of this paper is to summarize the research progress on the regulation of PDLSCs on various immune cells and the effect of the inflammatory environment on the immune characteristics of PDLSCs to provide an important theoretical basis for the allotransplantation of PDLSCs and improve the therapeutic effect of periodontal tissue regeneration. Studies have shown that PDLSCs possess a certain degree of immunosuppressive effect on both innate and acquired immune cells, and inflammatory stimulation may lead to the impairment of the immunoregulatory properties of PDLSCs. However, current studies are mainly limited to in vitro cell tests and lack in-depth studies on the immunomodulatory effects of PDLSCs in vivo. In vivo studies based on cell lineage tracing and conditional gene knockout technology may become the main directions for future research.

Initiation and maintenance of acquired immunity in dry eye / 国际眼科杂志(Guoji Yanke Zazhi)

Dry eye(DE)is a multifactorial ocular surface disorder arising from numerous pathologies. The pathogenesis of DE includes immune inflammation, oxidative stress, changes in tear film composition, corneal nerve abnormalities, and meibomian gland dysfunction. Among them, the immune inflammatory response is the most crucial in the pathogenesis of DE, which is regulated by both innate and acquired immune responses on the ocular surface. Multiple environmental stresses trigger the ocular surface innate immune response leading to corneal epithelial cell damage and inflammation and activate acquired immunity to participate in the ocular surface immune inflammatory response. Currently, multiple immune cells and inflammatory factors have been shown to be involved in the occurrence and development of DE. This article reviewed the immune progress and focused on the initiation and maintenance of acquired immunity in DE. Through the analysis of the latest viewpoints and research hot spots, we systematically introduced the immunomodulating mechanism underlying the mechanisms of the pathogenesis of DE and provided references for the prevention and treatment of DE.

Current status of AIDS knowledge, attitudes, practices and associated factors of high risk sexual behavior among college students in Tianjin City / 中国学校卫生

Objective@#To understand the current status of acquired immunodeficiency syndrome (AIDS) knowledge, attitudes, and practices of college students in Tianjin City and to further investigate the associated factors of high risk sexual behaviors, so as to provide a scientific and theoretical basis for accurate prevention and treatment of AIDS.@*Methods@#A stratified cluster random sample of 64 697 students in 56 colleges and universities in Tianjin City in November to December 2022 was investigated about the current status of AIDS knowledge, attitudes and practices. Information was collected using online survey via Questionnaire Star. Descriptive analysis was used for the current status of AIDS knowledge, attitudes and practices among college students. Chi square test and multiple Logistic regression analysis were used to analyze the influencing factors of high risk sexual behavior among college students.@*Results@#The AIDS awareness rate of college students in Tianjin City reached 87.33%. The sexual openness rate was 70.73 %. Among the 3 463 students who had sex during the past year, 42.13% of students reported high risk sexual behavior. Multivariate Logistic regression showed that female, having a romantic partner, having received sex education and prevention and treatment knowledge of AIDS were negatively associated with high risk sexual behavior ( OR =0.66, 0.59, 0.81, 0.59, P <0.05). Being in sophomore year, non heterosexuality (homosexuality, bisexuality, not knowing), prejudice against AIDS, and misunderstanding the testing methods for AIDS showed positive correlations with highrisk sexual behavior ( OR =1.22, 2.49, 2.30, 3.17, 1.43, 1.22 , P <0.05).@*Conclusions@#The awareness rate of AIDS in college students in Tianjin is high, but high risk sexual behaviors are still at a high level. Further targeted knowledge education and behavioral interventions are needed to scientifically prevent the spread of AIDS.

Among them, 97 patients had myopia(86.6%). There were 93 patients(83.0%)who spent more than 8 h on near work. The age group &#x003C;18 years old had the shortest duration before surgery, with a median time of 1.00(0.50, 1.00)a, the minimum negative diopter, with a median diopter of -0.75(-3.19, -0.56)D in the right eye and the diopter of -1.25(-2.81, -0.75)D in the left eye, and the maximum preoperative near angle of deviation, with a median angle of 30.00(18.50, 80.00)PD, and the maximum preoperative distant angle of deviation, with a median angle of 35.00(23.75, 80.00)PD. All these differences were statistically significant compared with other two groups(both P&#x003C;0.05). For the age group from 18 to 45 years old, the median near angle of deviation was 20.00(14.00, 30.00)PD, and the median distant angle of deviation was 25.00(20.00, 35.00)PD, both of which were higher than those in the age group &#x003E;45 years old(both P&#x003C;0.05). For the age group &#x003E;45 years old, the median near angle of deviation after surgery was -4.50(-7.50, 0)PD, and the median distant angle of deviation after surgery was 4.50(0, 9.50)PD, which were smaller than those in other two groups(all P&#x003C;0.05). The age group &#x003E;45 years old had the hiughest surgical success rate(100%). The preoperative stereopsis was better in age group &#x003E;45 years old than the group &#x003C;18 years old(P&#x003C;0.05). The postoperative stereopsis of the age group of 18 to 45 years old and the age group &#x003E;45 years old was better than age group &#x003C;18 years old(both P&#x003C;0.05).CONCLUSION: Surgical patients with AACE are mainly in the age group from 18 to 45 years old. The characteristic of angle of deviation is that distant angle of deviation is greater than near angle of deviation. The patients &#x003C;18 years old have larger preoperative angles of deviation than adults, while their stereoacuity is worse than adults in the early postoperative period. It is recommended that augmented-dose surgery should be performed in AACE patients who are in the age group of 18 to 45 years old(5-10 PD). A conservative surgery should be designed for hyperopia young children without established binocular vision.

Avances en políticas públicas y vigilancia epidemiológica relacionadas con el virus de inmunodeficiencia humana/sida en Ecuador

El virus de inmunodeficiencia humana constituye uno de los principales problemas de salud a nivel mundial. Se reconoce como un fenómeno multifactorial, donde las políticas públicas en materia de prevención, diagnóstico oportuno y tratamiento resultan claves. El objetivo del presente estudio es describir los avances en políticas públicas y vigilancia epidemiológica relacionadas con el virus de inmunodeficiencia humana/sida en Ecuador. Se evidencian importantes pasos con respecto al compromiso político y responsabilidad social para conseguir frenar los estragos del virus de inmunodeficiencia humana/sida, e infecciones de transmisión sexual, a partir de estrategias centradas en la prevención, así como en el tratamiento profiláctico, antirretroviral, y el seguimiento de los pacientes. Con vistas a ello se han implementado proyectos destinados a cumplir lo acordado en la declaración de las Naciones Unidas, y en el marco del plan nacional para el desarrollo. Persisten dificultades relacionadas con el acceso al diagnóstico del virus y pruebas de seguimiento, principalmente por la concentración de estas en una única institución.

The human immunodeficiency virus is one of the main health problems worldwide. It is recognized as a multifactorial phenomenon, where public policies regarding prevention, timely diagnosis and treatment are key. The objective of this study is to describe the advances in public policies and epidemiological surveillance related to the human immunodeficiency virus/AIDS in Ecuador. Important steps are evident in relation to political commitment and social responsibility to stop the injuries of the human immunodeficiency virus/AIDS, and sexually transmitted infections, based on strategies focused on prevention, as well as prophylactic, antiretroviral, and treatment patient follow-up. Some projects have been implemented aimed at fulfilling what was agreed in the United Nations declaration, and within the framework of the national development plan. Difficulties persist related to access to virus diagnosis and follow-up tests, mainly due to the concentration of these in a single institution.

Introducción: Uno de los desafíos del milenio a nivel mundial es combatir el avance de la epidemia del virus de la inmunodeficiencia humana/sida. Objetivo: Caracterizar a la población de pacientes con inicio clínico de sida según variables sociodemográficas y epidemiológicas. Métodos: Se realizó un estudio observacional y descriptivo, desde el 2017 hasta el 2021, de 87 personas diagnosticadas con inicio clínico del sida en la provincia de Santiago de Cuba. En el análisis estadístico se emplearon medidas de tendencia central y de dispersión, así como la distribución de frecuencias absolutas y relativas; también, se computaron intervalos de confianza de 95 % para las proporciones de las variables seleccionadas. Resultados: La edad promedio en la serie fue de 42 años (79,3 %); asimismo, predominaron el sexo masculino (91,9 %), el estado civil soltero (91,9 %), la vinculación laboral (72,4 %), los colores de la piel mestizo (52,8 %) y negro (39,3 %) y la procedencia urbana (73,5 %). El coito anal fue la principal forma de contagio (84,0 %), en tanto la mayoría de los afectados de ambos sexos (65,2 % en el masculino y 66,7 % en el femenino) no usaban el preservativo y en los hombres primó la homosexualidad (55,0 %). Conclusiones: El inicio clínico del sida predominó en hombres jóvenes solteros, con vínculo laboral, entre los cuales fueron muy significativas las conductas sexuales de riesgo.

Introduction: One of the millennium challenges worldwide is to fight the advance of the human immunodeficiency virus/aids. Objective: To characterize the sick population with clinical onset of AIDS according to sociodemographic and epidemiologic variables. Methods: An observational and descriptive study was carried out, from 2017 to 2021, of 87 people diagnosed with clinical onset of AIDS in Santiago de Cuba province. In the statistical analysis, measures of central tendency and dispersion were used, as well as the distribution of absolute and relative frequencies; also, confidence intervals of 95% were computed for the proportions of selected variables. Results: The average age in the series was 42 years (79.3%), likewise, there was a prevalence of the male sex (91.9%), single as marital status (91.9%), working bond (72.4%), mixed race (52.8%) and black skin color (39.3%), and the urban origin (73.5%). The anal coitus was the main way of infection (84.0%), while the majority of the affected individuals of both sexes (65.2% in males and 66.7% in females) did not use condoms and homosexuality predominated among men (55.0%). Conclusions: The clinical onset of AIDS prevailed in young and single men, with working bond, among whom risky sexual behaviors were very significant.

Abandono de la terapia antirretroviral entre adolescentes y jóvenes con VIH/SIDA durante el COVID-19: un estudio de casos y controles / Antiretroviral therapy abandonment among adolescents and young people with HIV/AIDS during COVID-19: A case-control study / Abandono da terapia antirretroviral entre adolescentes e jovens com HIV/aids durante a COVID-19: estudo caso-controle

Objetivo: identificar los factores asociados al abandono de la terapia antirretroviral entre adolescentes y jóvenes que vivían con VIH/sida durante la pandemia de COVID-19. Método: estudio de casos y controles realizado entre 2020 y 2021 en Maringá, Paraná. Los casos fueron: adolescentes y jóvenes (10 a 24 años) diagnosticados con VIH/sida y que abandonaron el tratamiento, mientras que el grupo de controles fue compuesto por personas con características sociodemográficas semejantes, diagnosticadas con VIH/sida, sin historia de abandono del tratamiento. El emparejamiento de casos y controles se hizo por conveniencia, con cuatro controles por cada caso. El instrumento de investigación presentó variables sociodemográficas y clínicas, entre otras y la asociación con el abandono del tratamiento se analizó por regresión logística. Resultados: se incluyeron 27 casos y 109 controles en el estudio (proporción 1/4). La variable asociada con mayor probabilidad de abandono fue la edad próxima a 22,8 años (ORaj:1,47; IC 95%:1,07-2,13; p=0,024). El uso esporádico del preservativo (ORaj:0,22; IC 95%:0,07-0,59; p=0,003) y padecer una infección oportunista (OR:0,31; IC 95%:0,10-0,90; p=0,030) fueron factores protectores. Conclusión: la edad próxima a los 23 años en la última visita se asoció al abandono de la terapia antirretroviral. La presencia de infección oportunista y el uso de preservativos son factores determinantes para la continuidad del tratamiento durante el COVID-19.

Objective: to identify the factors associated with antiretroviral therapy abandonment among adolescents and young people living with HIV/AIDS during the COVID-19 pandemic. Method: a case-control study carried out between 2020 and 2021 in Maringá, Paraná. The cases corresponded to the following: adolescents and young people (aged from 10 to 24 years old) diagnosed with HIV/AIDS and who abandoned treatment, while the Control Group consisted of people with similar sociodemographic characteristics, diagnosed with HIV/AIDS and with no history of treatment abandonment. Pairing of the cases and controls was by convenience, with four controls for each case. The research instrument presented sociodemographic variables, clinical characteristics and others, whose association with treatment abandonment was analyzed by means of logistic regression. Results: a total of 27 cases and 109 controls were included in the study (1/4 ratio). The variable associated with an increased chance of abandonment was age close to 22.8 years old (ORadj: 1.47; 95% CI: 1.07-2.13; p=0.024). Sporadic condom use (ORadj: 0.22; 95% CI: 0.07-0.59; p=0.003) and having an opportunistic infection (OR: 0.31; 95% CI: 0.10-0.90; p=0.030) were protective factors. Conclusion: age close to 23 years old at the last consultation was associated with antiretroviral therapy abandonment. The presence of opportunistic infections and condom use are determining factors for treatment continuity during COVID-19.

Sarcoma de Kaposi, sífilis e neurocriptococose em paciente HIV positivo / Kaposi's sarcoma, syphilis and neurocryptococcosis in an HIV-positive patient

A infecção pelo vírus da imunodeficiência humana (HIV) tornou-se um problema de saúde pública em todo o mun-do nas últimas décadas. A principal característica do HIV é a supressão do sistema imunológico pelo ataque aos linfócitos T CD4+ que enfraquece o sistema imunológico e torna o indivíduo suscetível a infecções oportunistas, neoplasias secundárias e doenças neurológicas. Este estudo objetiva relatar e discutir o caso de um paciente HIV positivo que apresentou concomitantemente Sarcoma de Kaposi (SK), sífilis e neurocriptococose, todas doenças relacionadas ao HIV. Trata-se de um paciente masculino, 31 anos, que procurou o serviço do hospital de referência com lesões cutâneas violáceas em face, membros superiores e tórax, com três meses de evolução. Ao exame dermatológico exibiu placas eritematovioláceas infiltrativas, com bordas regulares, elevadas, descamativas e com diâmetros variáveis. Obteve sorologia positiva para anticorpos anti-HIV e VDRL, iniciando protocolos de terapia antirretroviral (TARV) e de tratamento para sífilis. O paciente retornou ao serviço 30 dias após alta hospitalar, com queixa de cefaleia de forte intensidade, refratária à analgesia com opioides, associada a vômitos persistentes. Re-alizada tomografia computadorizada de crânio, sem alterações, e, posteriormente, punção liquórica que evidenciou a presença de criptococo. Iniciado esquema terapêutico para neurocriptococose e realizadas outras duas punções liquóricas para alívio do quadro álgico. Este relato está de acordo com o que presume a literatura médica, reafirmando que pacientes HIV positivos apresentam maior predisposição para condições como o SK, a sífilis e a neurocriptococose. Dessa forma, o estudo ilustra com ineditismo a ocorrência simultânea de complexas manifestações clínicas no mesmo paciente imunossuprimido (AU).

Human immunodeficiency virus (HIV) infection has become a worldwide public health problem in recent decades. The main characteristic of HIV is the suppression of the immune system by attacking CD4+ T lymphocytes, which weakens the immune system and makes the individual susceptible to opportunistic infections, secondary neoplasms, and neurological diseases. This study aims to report and discuss the case of an HIV-positive patient who presented concomitantly Kaposi's Sarcoma (KS), primary syphilis, and neurocryptococcosis, all HIV-related. This is a 31-year-old male patient who sought care at the reference hospital with violaceous skin lesions on the face, upper limbs and chest, with a three-month evolution. Dermatological examination showed infiltrative erythematous-violet plaques, with regular, elevated, scaly edges and varying diameters. He obtained positive serology for anti-HIV and VDRL antibodies, initiating antiretroviral therapy (ART) and treatment protocols for primary syphilis. The patient re-turned to the service 30 days after hospital discharge, complaining of severe headache, refractory to analgesia with opioids, associated with persistent vomiting. Cranial computed tomography was performed and did not demonstrate alterations; later CSF puncture showed the presence of cryptococcus. A therapeutic scheme for neurocryptococcosis was started, and two other CSF punctures were performed to relieve the pain. This report agrees with the medical literature, reaffirming that HIV-positive patients present a greater predisposition to conditions such as KS, syphilis, and neurocryptococcosis. Thus, the study illustrates with uniqueness the simultaneous occurrence of complex clinical manifestations in the same immunosuppressed patient (AU),

According to sexual orientation, homosexuals occupied 58.2%, and 32.1% belonged to the research group captured. Conclusions seropositive cases to the human immunodeficiency virus decreased significantly in the last five years, where patients of young adulthood were the most affected, as well as men who have sex with other men.

Survival of patients living with HIV and cancer in Cali, Colombia

Background: People living with HIV have an increased risk of cancer compared to the general population. However, with the increase in life expectancy and advances in antiretroviral therapy, the survival of patients with cancer and HIV has changed. Objective: To determine the survival of patients living with HIV and cancer in Cali, Colombia Methods: A retrospective cohort study was conducted at the Fundación Valle del Lili, Cali, Colombia. Data from the HIV database was crossed with data from the hospital and population-based cancer registries between 2011-2019. Patients <18 years, limited available clinical information on the diagnosis and treatment of HIV and cancer, and non-oncological tumor diagnosis were excluded. Results: A total of 173 patients were included. The frequencies of AIDS-defining neoplasms were: Non-Hodgkin lymphoma (42.8%), Kaposi sarcoma (27.8%), and cervical cancer (4.6%). Overall survival was 76.4% (95% CI 68.9-82.3) at five years. Poorer survival was found in patients with AIDS-defining infections (56.9% vs. 77.8%, p=0.027) and non-AIDS-defining infections (57.8% vs. 84.2%, p=0.013), while there was better survival in patients who received antiretroviral therapy (65.9% vs. 17.9%, p=0.021) and oncological treatment (66.7% vs. 35.4%, p<0.001). The presence of non-AIDS-defining infections increases the risk of dying (HR = 2.39, 95% CI 1.05-5.46, p=0.038), while oncological treatment decreases it (HR = 0.33, 95% CI 0.14-0.80, p=0.014). Conclusions: In people living with HIV, Non-Hodgkin lymphoma and Kaposi sarcoma are the most common neoplasms. Factors such as AIDS-associated and non-AIDS-associated infections have been identified as determinants of survival. Cancer treatment seems to improve survival.

Antecedentes: Las personas que viven con VIH tienen un riesgo mayor de cáncer en comparación con la población general. Sin embargo, con el aumento de la esperanza de vida y los avances en la terapia antirretroviral, la supervivencia de los pacientes con cáncer y VIH ha cambiado. Objetivo: Determinar la supervivencia de los pacientes que viven con VIH y cáncer en Cali, Colombia. Métodos: Se realizó un estudio de cohorte retrospectivo en la Fundación Valle del Lili, Cali, Colombia. Los datos de la base de datos de VIH se cruzaron con los datos de los registros de cáncer de base hospitalaria y poblacional entre 2011-2019. Se excluyeron los pacientes <18 años, con información clínica limitada disponible sobre el diagnóstico y tratamiento del VIH y el cáncer y los casos con diagnóstico de tumor no oncológico. Resultados: Se incluyeron un total de 173 pacientes. Las frecuencias de neoplasias definitorias de SIDA fueron: linfoma no Hodgkin (42.8%), sarcoma de Kaposi (27.8%) y cáncer cervical (4.6%). La supervivencia global fue del 76.4% (IC 95% 68.9-82.3) a los cinco años. Se encontró una peor supervivencia en pacientes con infecciones definitorias de SIDA (56.9% vs. 77.8%, p=0.027) e infecciones no definitorias de SIDA (57.8% vs. 84.2%, p=0.013), mientras que hubo una mejor supervivencia en pacientes que recibieron terapia antirretroviral (65.9% vs. 17.9%, p=0.021) y tratamiento oncológico (66.7% vs. 35.4%, p<0.001). La presencia de infecciones no definitorias de SIDA aumentó el riesgo de morir (HR = 2.39, IC 95% 1.05-5.46, p=0.038), mientras que el tratamiento oncológico lo disminuyó (HR = 0.33, IC 95% 0.14-0.80, p=0.014). Conclusiones: En las personas que viven con VIH, el linfoma no Hodgkin y el sarcoma de Kaposi son las neoplasias más comunes. Se han identificado factores como las infecciones asociadas al SIDA y las infecciones no asociadas al SIDA como determinantes de la supervivencia. El tratamiento del cáncer parece mejorar la supervivencia.

Reconstrução da ponta nasal: relatos de casos e revisão histórica / Nasal tip reconstruction: case reports and historical review

As amputações traumáticas da ponta nasal são lesões desfigurantes, que determinam importante rejeição social, impondo ao paciente um sofrimento adicional, além daqueles já causados pela ferida e suas limitações funcionais decorrentes do traumatismo. Tais defeitos representam um desafio para os cirurgiões plásticos, e existem diversas técnicas que poderão ser adotadas para tratar este mesmo tipo de defeito. Neste trabalho são mostrados inicialmente três casos de amputação traumática exclusivamente da ponta nasal com seus respectivos tratamentos, para em seguida apresentar uma revisão histórica e discussão das diversas técnicas utilizadas para reconstrução da ponta nasal, avaliando comparativamente e enfatizando a evolução técnica no armamentário da cirurgia plástica.

Traumatic amputations of the nasal tip are disfiguring injuries, which determine important social rejection, imposing additional suffering on the patient and those already caused by the wound and its functional limitations resulting from the trauma. Such defects represent a challenge for plastic surgeons, and several techniques can be adopted to treat this type of defect. This work shows three cases of traumatic amputation exclusively of the nasal tip with their respective treatments. They present a historical review and discussion of the different techniques used for nasal tip reconstruction, comparatively evaluating and emphasizing the technical evolution in plastic surgery armament.
