Depressive symptoms in elderly medical-surgical patients hospitalized in community settings.

The authors examined the rates and correlates of depressive symptoms in adults over age 60 admitted to community hospital settings and compared them with patients admitted to a tertiary-care medical center. Rates of depressive symptoms in patients admitted to five different community hospitals in North Carolina were compared with each other and with a sample of 542 elderly medical patients admitted to Duke University Medical Center (DUMC). Compared with patients at DUMC, community-hospital patients were older and had more cognitive impairment, but had less severe medical illness and shorter hospital stays. The proportion of depressed community patients was significantly higher than among patients admitted to DUMC. In four of the five community hospitals, rates of significant depressive symptoms exceeded 50%. Health correlates of depression were admitting diagnoses other than cardiovascular disease, poor cognitive functioning, and severe medical illness.

Effect of vest cardiopulmonary resuscitation rate on cardiac output and coronary blood flow.

We studied the effect of CPR rate on the hemodynamic indices of surgically instrumented canine experimental models. Using pneumatic vest CPR, we applied simultaneous rib cage and abdominal compressions at rates of 1 to 12 Hz. CPR with 2-Hz frequency yielded the highest aortic and coronary flows (252 +/- 14 and 6.8 +/- 1.1 ml/min vs. 178 + 12 and 0.96 +/- 0.08 ml/min at 1 Hz, respectively; p less than .005). The validity of the present American Heart Association recommendation for 1-Hz CPR rate would benefit from further studies.

Bleeding small-bowel varices.

A case of bleeding jejunal varices in a 27-year-old man is reported. Portal hypertension resulted from portal vein thrombosis and the varices were not associated with portasystemic shunting. Because mesenteric varices are rare, they are seldom the cause of gastrointestinal hemorrhage. However, they should be suspected in patients with an obscure source of bleeding and portal hypertension. The pathogenesis, roentgenographic criteria and surgical management are discussed.
