AI Article Synopsis
- The study aimed to evaluate an intensive chemotherapy regimen for patients suffering from HIV-associated non-Hodgkin lymphoma (NHL) to find an effective treatment method without worsening their immunodeficiency.
- Thirty-eight patients underwent a series of chemotherapy treatments along with antiretroviral therapy, showing a 60.5% complete response rate and 79% overall response rate, with significant improvement in viral load and survival rates.
- The findings suggest that intensive chemotherapy can be both effective and tolerable for treating HIV-associated NHL, although the levels of CD4-positive T lymphocytes decreased slightly post-treatment.
Article Abstract
Background: Optimal treatment of human immunodeficiency virus (HIV)-associated non-Hodgkin lymphoma (NHL) has yet to be defined, because chemotherapy could exacerbate immunodeficiency, with subsequent adverse effects for patients.
Methods: The authors investigated the feasibility of an intensive chemotherapy regimen for HIV-associated NHL. Thirty-eight patients were treated with a first course of cyclophosphamide (Cy), vincristine, and prednisone; followed by 3 courses of high-dose Cy (2000 mg/m2), doxorubicin (Doxo; 50 mg/m2), vincristine, and prednisone (modified high-dose CHOP); 1 course of high-dose methotrexate (MTX; 8000 mg/m2); and 1 course of high-dose cytarabine (8000 mg/m2). Radiotherapy was added to the treatment regimen for patients with bulky disease or residual tumor. Chemotherapy was administered in conjunction with granulocyte-colony-stimulating factor and antiretroviral therapy.
Results: Patients received 91.5%, 93%, 66%, and 63% of the scheduled doses of Cy, Doxo, MTX, and cytarabine, respectively. The complete response rate was 60.5%, with a total response rate of 79%. The 40-month overall survival rate was 43%, the disease-free survival rate was 65%, and the recurrence-free survival rate was 39%. Both an International Prognostic Index score of 0 or 1 and Burkitt-type histology had positive effects on survival, whereas CD4-positive lymphocyte counts, viral burden, and previous highly active antiretroviral therapy did not. CD4-positive T lymphocyte levels decreased from 0.197 +/- 0.156 x10(9)/L before treatment to 0.152 +/- 0.1 x10(9)/L at 6 months after the end of treatment. A decrease in viral load, from 380,000 +/- 785,000 copies/mL before treatment to 25,000 +/- 43,000 copies/mL at 6 months after the end of treatment, also was observed.
Conclusions: The results of the current study indicate that intensive chemotherapy is effective and tolerable for patients with HIV-associated NHL.

Background: Fulminant virus-associated encephalopathy (VAE) is a rare complication of viral infection that presents as acute brain dysfunction and requires respiratory support and/or vasoactive agents. However, the mechanism of VAE is undetermined. The mortality rate is high since there is no specific treatment for fulminant VAE.

Background: Lithium disilicate occlusal veneers are popular for minimally invasive posterior teeth restoration. The aim of this study was to compare the fatigue resistance and crack pattern of lithium disilicate occlusal veneers fabricated using pressing and milling techniques with varying thicknesses.
Methods: Sixty lithium disilicate discs, representing occlusal veneers, were divided into four groups (n = 15) based on processing technique (IPS e.

Background: The Senhance digital laparoscopic system (Senhance) is a surgical robot approved for use in Japan after the da Vinci system. Our institution was the first to introduce this system, which has been used primarily for gastrointestinal surgery. Featuring tactile feedback, eye-movement-controlled camera operation, stereoscopic vision, and magnification, the short-term postoperative outcomes of the Senhance in abdominal surgery have been documented.

Background: Colorectal cancer (CRC) frequently metastasizes to the liver, significantly worsening patient outcomes. While hepatectomy offers the best curative option for colorectal liver metastases (CRLM), margin recurrence remains a major challenge post-surgery. Intraoperative ultrasound (IOUS) aids tumor identification and margin determination, but its limitations in laparoscopic surgery necessitate additional methods.

Migratory animals rely on multiple sites during their annual cycles. Deteriorating conditions at any site can have population-level consequences, with long-distance migrants seen as especially susceptible to such changes. Reduced adult survival caused by persecution at non-breeding sites has been suggested a major reason for the catastrophic decline of a formerly abundant, long-distance migratory songbird, the Yellow-breasted Bunting Emberiza aureola.
