The results of this meta-analysis suggest that, in those patients receiving enteral nutrition, stress ulcer prophylaxis may not be required and, indeed, such therapy may increase the risk of pneumonia and death. However, because no clinical study has prospectively tested the influence of enteral nutrition on the risk of stress ulcer prophylaxis, our findings should be considered exploratory and interpreted with some caution.
This urban population of HIV-infected persons has a relatively high prevalence of obstructive lung disease as assessed by spirometry. Furthermore, the high prevalence of obstructive lung disease in never smokers may suggest a possible association between HIV infection and emphysema. In addition the SGRQ total score was comparatively higher in patients with obstruction on spirometry. Our data suggests that potentially all patients with HIV should be screened a for OLD.
The mortality rate of pulmonary hypertension in pregnancy is 25%–56%. Pulmonary arterial hypertension is the highest incidence among this group, especially in young women. Despite clear recommendation of pregnancy avoidance, certain groups of patients are initially diagnosed during the gestational age step into the third trimester. While the presence of right ventricular failure in early gestation is usually trivial, it can be more severe in the late trimester. Current evidence shows no consensus in the management and serious precautions for each stage of the pre-, peri- and post-partum periods of this specific group. Pulmonary hypertension-targeted drugs, mode of delivery, type of anesthesia, and some avoidances should be planned among a multidisciplinary team to enhance maternal and fetal survival opportunities. Sudden circulatory collapse from cardiac decompensation during the peri- and post-partum phases is detrimental, and mechanical support such as extracorporeal membrane oxygenation should be considered for mitigating hemodynamics and extending cardiac recovery time. Our review aims to explain the pathophysiology of pulmonary arterial hypertension and summarize the current evidence for critical management and precautions in each stage of pregnancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
