New Therapeutic Options in Patients Prone to Hypertension: A Focus on Direct Renin Inhibition and Aldosterone Blockade

Certain patient populations have a high prevalence of hypertension, including black, elderly, or obese patients; patients with metabolic syndrome, or frank diabetes; and patients with chronic kidney disease. Many of these patients experience renin-angiotensin-aldosterone system (RAAS) dysregulation, which is important because the RAAS plays a pivotal role in the pathogenesis of hypertension, cardiovascular disease, and renal dysfunction. Data available regarding newer approaches that target the RAAS, including direct renin inhibition and aldosterone receptor antagonism, in patients who often have hypertension are reviewed. Aliskiren, the first direct renin inhibitor, is effective in a number of these patient groups, including those who are black or obese or who have metabolic syndrome, renal impairment, or diabetes. In addition, in the setting of long-term angiotensin-converting enzyme inhibitor or angiotensin receptor blocker therapy, aldosterone receptor antagonists (spironolactone and eplerenone) provide another rational therapeutic approach for patients whose blood pressure is not controlled by standard therapies.     

Private prayer as a suitable intervention for hospitalised patients: a critical review of the literature

Aim. This critical review seeks to identify if there is evidence that private (personal) prayer is capable of improving wellbeing for adult patients in hospital. Background. The review was conducted in the belief that the spiritual needs of hospitalised patients may be enhanced by encouragement and support to engage in prayer. Design. Systematic review. Method. A systematic approach was used to gather evidence from published studies. In the absence of experimental research involving this type of population, evidence from qualitative and correlational studies was critically reviewed. Results. The findings indicate that private prayer, when measured by frequency, is usually associated with lower levels of depression and anxiety. Most of the studies that show positive associations between prayer and wellbeing were located in areas that have strong Christian traditions and samples reported a relatively high level of religiosity, church attendance and use of prayer. Church attenders, older people, women, those who are poor, less well educated and have chronic health problems appear to make more frequent use of prayer. Prayer appears to be a coping action that mediates between religious faith and wellbeing and can take different forms. Devotional prayers involving an intimate dialogue with a supportive God appear to be associated with improved optimism, wellbeing and function. In contrast, prayers that involve pleas for help may, in the absence of a pre‐existing faith, be associated with increased distress and possibly poorer function. Conclusion. Future research needs to differentiate the effects of different types of prayer. Relevance to clinical practice. Encouragement to engage in prayer should be offered only following assessment of the patient’s faith and likely content and form of prayer to be used. Hospitalised patients who lack faith and whose prayers involve desperate pleas for help are likely to need additional support from competent nursing and chaplaincy staff.     

Tid1 functions as a tumour suppressor in head and neck squamous cell carcinoma

Human tumourous imaginal disc (Tid1), a human homologue of the Drosophila tumour suppressor protein Tid56, is involved in multiple intracellular signalling pathways such as apoptosis, cell proliferation, and cell survival. Here, we investigated the anti‐tumourigenic activity of Tid1 in head and neck squamous cell carcinoma (HNSCC) in vitro and in vivo. Firstly, the clinical association between Tid1 expression and progression of HNSCC was explored. It was found that expression of Tid1 was negatively associated with tumour status, recurrence, and survival prognosis using immunohistochemical analysis of primary HNSCC patient tumour tissue. Secondly, ectopic expression of Tid1 in HNSCC cells was shown to significantly inhibit cell proliferation, migration, invasion, anchorage‐independent growth, and xenotransplantation tumourigenicity. Thirdly, we showed that overexpression of Tid1 attenuated EGFR activity and blocked the activation of AKT in HNSCC cells, which are known to be involved in the regulation of survival in HNSCC cells. On the other hand, ectopic expression of constitutively active AKT greatly reduced apoptosis induced by Tid1 overexpression. Together, these findings suggest that Tid1 functions as a tumour suppressor in HNSCC tumourigenesis. Copyright © 2009 Pathological Society of Great Britain and Ireland.
