OBJECTIVE: To determine whether adherence to clinic visits early after initiation of highly active antiretroviral therapy (HAART) is predictive of long-term clinical outcome. DESIGN: Observational cohort study. SETTING: A tertiary referral hospital. SUBJECTS: A total of 387 adult HIV patients who were followed for at least 1 year after initiation of HAART between January 1998 and December 2004. MAIN OUTCOME MEASUREMENTS: The effect of 1-year adherence to clinic visits on the occurrence of new AI

infections (8,9). This rate was even in the lower range of values found among HIV-infected heterosexual persons in industrialized countries (9%-27%) (2). Our results therefore suggest that the high seroprevalence rates of HIV and HCV in Africa will not necessarily result in a high prevalence of HIV/HCV coinfection.

We performed a retrospective study to determine the influence of bacteremia on the mortality of patients with spontaneous bacterial peritonitis (SBP), a major complication of liver cirrhosis. Patients with SBP with identified pathogens from ascites and/or blood were analyzed by retrospective review of clinical and laboratory records in a university hospital in Korea for 3 y and classified into the bacteremic and non-bacteremic groups. The underlying liver function was determined by model for end

The proportion of tuberculosis manifested by immune reconstitution inflammatory syndrome (IRIS) after HAART has not been established. We describe the incidence and clinical features of tuberculosis manifested by IRIS after HAART in an intermediate tuberculosis burden area. The findings suggest that a significant proportion of the tuberculosis occurring early after starting HAART is manifested by IRIS.

Little is known about the effect of immune reconstitution inflammatory syndrome (IRIS) on the long-term clinical outcome. Of 52 opportunistic infections (OI) occurring within one year after the start of HAART in 387 HIV patients, 33 (63%) were classified as having IRIS. The patients with IRIS showed no significant difference in the AIDS event-free survival curve compared with the matched control group without OI and in contrast to non-IRIS OI.

Use of a multimodal generative artificial intelligence model increased the efficiency and quality of chest radiograph interpretations by reducing reading times and increasing report accuracy and agreement.

Although the importance of the initial regimen in highly active antiretroviral therapy (HAART) has been emphasized, the effect on clinical outcome of early modification of the initial HAART regimen has not been well-defined. The analysis included antiretroviral-naive HIV patients who started HAART between 1999 and 2005 at a university hospital. Early modification was defined as any drug change within 2 months of starting HAART. The effect of early regimen modification on the occurrence of new AI

Primary drug resistance is an emerging problem in HIV infections. We have investigated the current prevalence of primary resistance in Korea and compared it with previous data. Drug-naive HIV patients attending the outpatient clinic of Seoul National University Hospital between April and August 2006 were enrolled. A medical interview and a genotypic resistance test were performed for each patient. The International AIDS Society-USA Panel consensus statement issued in 2006 was used to define resi

Invasion of vascular endothelial cells by Staphylococcus aureus is associated with diverse complications and recurrent infection. Little is known about the effect of salicylic acid, the major metabolite of aspirin, on the interaction between S. aureus and vascular endothelial cells. We examined the adhesion of S. aureus strain 8325-4 cultured with or without salicylic acid to human umbilical vein endothelial cells (HUVECs), and the ability of the strain to invade these cells. Strain 8325-4 cells

A domain-specific multimodal generative AI model demonstrated potential for high diagnostic accuracy and clinical value in providing preliminary interpretations of chest radiographs for radiologists.

Kocuria kristinae, part of the normal flora of the skin and oral mucosa, is seldom reported as a human pathogen; infection is mostly associated with immunocompromised patients in healthcare facilities. Here, we describe the first case of bacteremic empyema caused by K. kristinae acquired from the community. K. kristinae was isolated from pleural effusion and two sets of peripheral blood samples drawn from two different sites. The empyema resolved after the insertion of a chest tube and intraveno

Invasion of vascular endothelial cells is thought to be a critical step in the development of metastatic infections in patients with Staphylococcus aureus bacteraemia. This study was designed to evaluate the association between the ability to invade endothelial cells and metastatic infection by S. aureus. Patients with metastatic infection were identified among those with community-acquired S. aureus bacteraemia in a tertiary referral hospital. Patients with simple bacteraemia caused by S. aureu
