Pulmonary tuberculosis (TB) is caused by Mycobacterium tuberculosis. The protein composition of sputum may reflect the immune status of the lung. This study aimed to evaluate the protein profiles in spontaneous sputum samples from patients with active pulmonary TB. Sputum samples were collected from patients with pulmonary TB and healthy controls. Western blotting was used to analyze the amount of interleukin 10 (IL-10), interferon-gamma (IFN-γ), IL-25, IL- 17, perforin-1, urease, albumin, transferrin, lactoferrin, adenosine deaminase (also known as adenosine aminohydrolase, or ADA), ADA-2, granzyme B, granulysin, and caspase- 1 in sputum. Results of detection of IL-10, IFN-γ, perforin- 1, urease, ADA2, and caspase-1, showed relatively high specificity in distinguishing patients with TB from healthy controls, although sensitivities varied from 13.3% to 66.1%. By defining a positive result as the detection of any two proteins in sputum samples, combined use of transferrin and urease as markers increased sensitivity to 73.2% and specificity to 71.1%. Furthermore, we observed that the concentration of transferrin was proportional to the number of acidfast bacilli detected in sputum specimens. Detection of sputum transferrin and urease was highly associated with pulmonary TB infection. In addition, a high concentration of transferrin detected in sputum might correlate with active TB infection. This data on sputum proteins in patients with TB may aid in the development of biomarkers to assess the severity of pulmonary TB.

Background/Aims: To validate the effectiveness of a newly developed light-emitting diode (LED)-narrow band imaging (NBI) system for detecting early malignant tumors in the oral cavity. Methods: Six men (mean age, 51.5 years) with early oral mucosa lesions were screened using both the conventional white light and LED-NBI systems. Results: Small elevated or ulcerative lesions were found under the white light view, and typical scattered brown spots were identified after shifting to the LED-NBI view for all six patients. Histopathological examination confirmed squamous cell carcinoma. The clinical stage was early malignant lesions (T1), and the patients underwent wide excision for primary cancer. This is the pilot study documenting the utility of a new LED-NBI system as an adjunctive technique to detect early oral cancer using the diagnostic criterion of the presence of typical scattered brown spots in six high-risk patients. Conclusions: Although large-scale screening programs should be established to further verify the accuracy of this technology, its lower power consumption, lower heat emission, and higher luminous efficiency appear promising for future clinical applications.

Purpose: Intimate partner violence (IPV) is a serious public health issue among women. IPV victims usually seek help from hospitals, and emergency nurses are the frontline staff with whom the victims come into contact first. This study examined the conditions and patterns of IPV in southern Taiwan. Methods: From designated hospitals in Kaohsiung under the Department of Health Injury Assessment Clinic, data were collected on 497 women regarding their injury assessment for IPV reported to the Kaohsiung City Government. Results: Taiwanese survivors were older compared to immigrant survivors. Taiwanese survivors also had higher education levels compared to immigrant survivors. Taiwanese survivors had higher employment rate than immigrant survivors did. The time between IPV and medical help seeking was longer for divorced than married women. Conclusions: These results can facilitate understanding of the conditions and patterns of IPV in Taiwan, increase the awareness of nurses, especially the emergency nurses for the prevention of IPV, and increase professional competency for the provision of appropriate healthcare services to survivors of IPV.

Monacolin K affects lipid metabolism through SIRT1/AMPK pathway in HepG2 cells

Monacolin K is the secondary metabolite isolatedfrom Monascus spp. It is the natural form of lovastatin,which is clinically used to reduce the synthesis of cholesterolby inhibiting 3-hydroxy-3-methylglutaryl coenzyme Areductase. In the present study, monacolin K increased proteinexpression of SIRT1 and phosphorylation level of AMPactivatedprotein kinase (AMPK) in HepG2 cells. Throughactivation of SIRT1/AMPK pathway, monacolin Kincreased phosphorylation of acetyl CoA carboxylase andcaused nuclear translocation of forkhead box O1. The westernblotting results showed that monacolin K increasedexpression of adipose triglyceride lipase but decreasedabundances of fatty acid synthase (FAS) and sterol regulatory element-binding protein 1 (SREBP1). MonacolinK also decreased the intracellular accumulation of lipids asdemonstrated by Oil Red O staining. In addition, theimmunostaining showed that monacolin K prevented thenuclear translocation of SREBP1, indicating the associationwith down-regulation of FAS. All the demonstrated effectsof monacolin K were counteracted by nicotinamide orcompound C, the inhibitors of SIRT1 orAMPK. In summary,monacolin K reduces the lipid content through SIRT1/AMPK pathway in HepG2 cells, which promotes catabolismand inhibits anabolism of lipid.

Purpose: This study aimed to explore the factors associated with the intention to receive a Pap test among married immigrant women of Vietnamese origin living in Taiwan. Methods: This was a cross-sectional community-based study.We enrolled 281 women aged 30 years and over in the study, from July 2013 to January 2014. The participants' characteristics, cervical cancer knowledge, Pap test knowledge, attitudes toward cervical cancer, barriers to receiving a Pap test, fatalism, and intention to receive a Pap test, were measured using self-report questionnaires. Hierarchical multiple regression analyses were performed to examine the variables associated with participants' intentions to receive a Pap test. Results: Vietnamese women with low scores on the measures of cervical cancer knowledge and perceived barriers to receiving a Pap test were more willing to receive the test, as were those with high scores on the measures of Pap test knowledge and fatalism. Women who received a Pap test in the previous year were more willing to receive a Pap test within the next 3 years. Conclusions: Preventive healthcare for immigrant women should be a focus of nurses. The development of culturally appropriate health education and strategies should enhance their knowledge of Pap tests and reduce perceived barriers to Pap test participation. This study's results can be a reference for nurses who work with immigrant women.

The purpose of this descriptive and comparative study was to examine gender differences relevant to pain intensity, opioid prescription patterns and opioid consumption in Taiwanese oncology outpatients. The 92 participants had been prescribed opioid analgesics for cancer-related pain at least once in the past week and were asked to complete the Brief Pain Inventory - Chinese questionnaire and to recall the dosage of each opioid analgesic that they had ingested within the previous 24 hours. For opioid prescriptions and consumption, all analgesics were converted to morphine equivalents. The results revealed a significant difference between males and female minimum pain thresholds (t = 2.38, p = 0.02) and current pain thresholds (t = 2.12, p = 0.04), with males reporting a higher intensity of pain than females. In addition, this study found that males tended to use prescribed opioid analgesics more frequently than females on the bases of both around the clock (ATC) (t = 1.90, p = 0.06) and ATC plus as needed (ATC + PRN) (t = 2.33, p = 0.02). However, there was no difference between males and females in opioid prescriptions on an ATC basis (t = 0.52, p = 0.60) or at an ATC + PRN basis (t = 0.40, p = 0.69). The results suggest that there may be a gender bias in the treatment of cancer pain, supporting the proposal of routine examination of the effect of gender on cancer pain management. These findings suggest that clinicians should be particularly aware of potential gender differences during pain monitoring and the consumption of prescribed opioid analgesics.
