Background: One under-explored area in chronic obstructive pulmonary disease (COPD) patients is anxiety and/or depression, which may have negative impact in the patients’ condition. This is possibly the first study to possibly assess the burden of anxiety and depression in COPD patients in the Philippines. Study Design: This is a prospective descriptive survey in three tertiary care hospitals in Manila, Philippines. Participants: A total of 204 patients were enrolled in the study with the following inclusion criteria: Filipino patients who are aged more than or equal to 40 years with a diagnosis of COPD (documented post-bronchodilator FEV1/FVC ratio less than 0.7) by a physician seen at the outpatient clinics of three tertiary care hospitals with no primary diagnosis of asthma, no previous lung volume reduction surgery, lung transplantation or pneumonectomy and at least finished Grade 2 education. Exclusion criteria include pregnant patients and patients previously diagnosed to have an anxiety, depression, or on any anti-depressant medications. Methods: Descriptive statistics was obtained with frequency and percentages of the demographic and physiologic variables in the study by tabulation and graph. The prevalence of anxiety and depression was determined by calculating the percentage of each patient with a score of 8 or higher on the Hospital Anxiety and Depression Scale (HADS) with validated Tagalog version, respectively. Results: The prevalence of anxiety in Filipino COPD patients is 47.55%. The prevalence of depression in Filipino COPD patients is 31.37%. Conclusion: The prevalence of depression in Filipino COPD patients is comparable to the prevalence of depression from other general medical conditions nationwide according to the study of Batar (31.37% vs. 31%). Anxiety is slightly more prevalent in COPD from other general medical conditions (47.55% vs. 36%). A study on the risk factors of anxiety and depression among Filipino COPD patients is recommended. © 2015, Philippine College of Physicians. All rights reserved.

Purpose: To examine the role of both protein kinase C (PKC)-and vascular endothelial growth factor receptor (VEGFR)-2 in malignant pleural mesothelioma (MPM) using respective inhibitors, enzastaurin and KRN633. Materials and Methods: MPM cell lines, control cells, and a variety of archived MPM tumor samples were used to determine the protein expression levels of PKC-β, VEGFR-2, VEGF, and p-AKT. Effects of enzastaurin and KRN633 on phosphorylation status of key signaling molecules and viability of the mesothelioma cells were determined. The common soil nematode, Caenorhabditis elegans, was treated with enzastaurin to determine its suitability to screen for highly potent kinase inhibitors. Results: PKC-β1, PKC-β2 and VEGFR-2/KDR were overexpressed in MPM cell lines and MPM tumor tissues. Enzastaurin treatment resulted in significant loss in viability of VEGF induced cell proliferation; however, the effect of KRN633 was much less. Enzastaurin also dramatically decreased the phosphorylation of PKC-β, its downstream target p-AKT, and surprisingly, the upstream VEGFR-2. The combination of the two drugs at best was additive and similar results were obtained with respect to cell viability. Treatment of C. elegans with enzastaurin resulted in clear phenotypic changes and the worms were hypermotile with abnormal pattern and shape of eggs, suggesting altered fecundity. Conclusions: PKC-β1 and VEGFR-2 are both excellent therapeutic targets in MPM. Enzastaurin was better at killing MPM cells than KRN633 and the combination lacked synergy. In addition, we show here that C. elegans can be used to screen for the next generation inhibitors as treatment with enzastaurin resulted in clear phenotypic changes that could be assayed. © 2011 Loganathan.

Pancreas | Year: 2011

Pancreatitis is a rare occurrence in patients with cystic fibrosis (CF) affecting 1.2% of all patients, but it can be the first presenting sign in approximately 15% of adults with pancreatic sufficiency and a milder CF phenotype. We report a case of a woman with recurrent pancreatitis who has one cystic fibrosis-causing mutation (G551D) and the first known description of a pathologic duplication of exon 19 of the CF transmembrane conductance regulator (CFTR). A 30-year-old white woman with 30 attacks of pancreatitis over a 5-year period starting at age 25 presented to the genetics department. She was found to have a mutation in the SPINK1 gene, IVS3+184T>A, and one cystic fibrosis-causing mutation (G551D) prompting full gene sequencing of the CFTR, revealing an additional duplication of exon 19. Sweat chloride testing was elevated at 97 and 106 mmol/L. Despite normal growth parameters and lung function, it is important to be aware of recurrent pancreatitis as a presenting sign of CF. Comprehensive CF gene analysis is necessary to detect a second CF-causing mutation that may put patients at risk for more severe symptoms of pancreatitis. There is a significant difference in the prevalence of heterozygote mutations between available testing methods. Copyright © 2011 by Lippincott Williams & Wilkins.
