Observational Study
10-year outcome of temporary structured treatment interruption (STI) among HIV-1-infected patients: An observational study in a single medical center.
Lifelong antiretroviral therapy (ART) is recommended for HIV-1 infected patients but may lead to intolerance or poor adherence. Structured treatment interruption (STI) is a strategy for drug holiday or to boost HIV-specific immunity. But the long-term outcome of STI was never reported in literature. ⋯ Temporary STI may not lead to worse long-term outcome among highly selected patients. The policy may partially control viral replication through reminding the HIV-1 specific T cell immunity.

Abbott RealTime Genotype II assay can effectively identify hepatitis C virus (HCV) genotypes (GTs), but some GT 6 subtypes might not be differentiated from GT 1. Abbott RealTime Genotype II PLUS and sequencing might be needed to resolve these ambiguous results. Unlike the high prevalence of GT 6 in Southeast Asia, GT 6 had rarely been reported in Taiwan except in intravenous drug abusers (IDU). But the prevalence of GT 6 in Taiwan might be underestimated. We conducted this study to determine the GTs in a HCV endemic area in Southern Taiwan. ⋯ GT 6 is the major factor for high ambiguous rate by GT II. Unexpected high prevalence of GT 6 (18.3%) in Southern Taiwan, especially subtype 6 g, closely related to Indonesian strains, is first reported.

Patients who have symptoms of sicca, such as dry eyes and mouth, may have Sjögren's syndrome (SS). However, the conservative culture makes patients hesitate to undergo an invasive biopsy, which contributes to the difficulty of confirming a diagnosis. We aimed to identify the characteristics of patients with sicca symptoms to develop a better predictive value for each item included in the three different diagnostic criteria for SS and clarify the best diagnostic tools for the local population. ⋯ Our results indicate the cut-off point for defining a positive test result in the Schirmer's test is worth modified to <10 mm/5 minutes in either eye.

Pulmonary veno-occlusive disease (PVOD) is a rare but fatal cause of pulmonary hypertension reported to be linked to mutations of eukaryotic initiation factor 2 alpha kinase 4 (EIF2AK4), also known as general control nonderepressible 2 kinase (GCN2). PVOD is difficult to diagnose and often initially misdiagnosed as other types of idiopathic pulmonary arterial hypertension (IPAH). To rapidly and correctly identify PVOD patients and explore the possible pathogenesis, we thoroughly investigated histopathological features and GCN2 protein levels in non-PAH, PVOD and PAH patients. ⋯ Our study is the first to show remarkable histological structures, including the wreath-like arrangement of a hyperplastic muscle bundle in the adventitia of pulmonary arteries, in PVOD patients as a diagnostic clue and to disclose the biological difference between PAH and PVOD in a Taiwanese population.

Mitochondrial assembly receptor (MasR), a receptor of angiotensin-(1-7), plays an important role in the anti-cancer effect of the peptide hormone. The aim of the current study was to evaluate the crucial role of angiotensin-(1-7)/MasR axis in esophageal squamous cell carcinoma (ESCC) patients who received curative esophagectomy. ⋯ Low expression of MasR may be associated with poor prognosis in ESCC patients receiving curative esophagectomy. Further cohort study with larger population, or a prospective study is warranted to validate this finding.
