Dehydroepiandrosterone (DHEA) and its interconvertible sulfate derivative (DHEA-S) are human androgenic steroids that have been reported to inhibit viral expression and have been associated with a decreased risk of cancer. The relationship between serum DHEA and DHEA-S levels and subsequent progression to AIDS was investigated in a sample of human immunodeficiency virus (HIV)-infected men from the San Francisco Men's Health Study followed prospectively since 1984. Among 108 men seropositive for HIV at study entry and with CD4 lymphocyte counts of 200-499 microliters 24 months later, serum DHEA levels below the lower limit of normal (less than 180 ng/dl) at this later date were predictive of subsequent progression to AIDS (relative hazard = 2.34; 95% confidence interval = 1.18-4.63; P = .01) after controlling for hematocrit, age, and log absolute CD4 cell number in a Cox proportional hazards model. This is the first large prospective cohort in which an endocrinologic variable has been observed to independently predict progression to AIDS. These observations, in addition to recent in vitro data, suggest that DHEA might have a protective effect in HIV infection.

Cytomegalovirus (CMV) pneumonia is an uncommon presentation of CMV among patients with HIV/AIDS, particularly in co-infection with pneumonia (PCP). A case was reported with a literature review, and a comprehensive literature search was performed using the PubMed/MEDLINE and Scopus databases. We report a 52-year-old male with AIDS presenting with progressively worsening dyspnea over 1 week.

Background: Small cell lung cancer (SCLC) accounts for 15% of all lung cancers and presents early metastasis and poor prognosis. Chemotherapy with cisplatin (CDDP) remains one of the standards of care in first-line treatment. However, the emergence of acquired resistance to CDDP causes disease progression and cancer recurrence.

Background: While automated methods for differential diagnosis of parkinsonian syndromes based on MRI imaging have been introduced, their implementation in clinical practice still underlies considerable challenges.
Objective: To assess whether the performance of classifiers based on imaging derived biomarkers is improved with the addition of basic clinical information and to provide a practical solution to address the insecurity of classification results due to the uncertain clinical diagnosis they are based on.
Methods: Retro- and prospectively collected data from multimodal MRI and standardized clinical datasets of 229 patients with PD (n = 167), PSP (n = 44), or MSA (n = 18) underwent multinomial classification in a benchmark study comparing the performance of nine machine learning methods.

The co-infection of HIV and (MTB) poses a severe challenge for the prevention and control of infectious disease, resulting in poor clinical outcomes of the patients and risk for wide spread. As steady progress in global health, the co-infection of HIV/MTB has been basically controlled, and the new cases are generally declining. However, its incidence remained high in resource-limited areas.

Retinal image registration is vital for diagnostic therapeutic applications within the field of ophthalmology. Existing public datasets, focusing on adult retinal pathologies with high-quality images, have limited number of image pairs and neglect clinical challenges. To address this gap, we introduce COph100, a novel and challenging dataset known as the Comprehensive Ophthalmology Retinal Image Registration dataset for infants with a wide range of image quality issues constituting the public "RIDIRP" database.
