PURPOSE

Endoscopy is recommended to screen for esophageal varices in patients with cirrhosis. The objective of this study was to identify features on abdominal CT imaging associated variceal hemorrhage (VH).

METHODS

A case-control study was performed among patients with cirrhosis who had a CT scan. Consecutive patients who experienced VH were included as cases, and patients without VH served as controls. Two radiologists recorded the maximal esophageal varix diameter in addition to other measures of portal hypertension at CT.

RESULTS

The most powerful CT parameter associated with VH was the esophageal varix diameter (5.8 vs. 2.7 mm, p < 0.001; adjusted OR 1.84 per mm, p = 0.009). 63% of individuals with VH had a maximal varix diameter ≥5 mm compared to 7.5% of cirrhotic patients without VH (p < 0.001). In contrast, the proportion of individuals whose largest varix was <3 mm was 7.4% among VH cases compared to 54.7% among controls (p = 0.001). The varix diameter powerfully discriminated those with and without VH (C-statistic 0.84).

CONCLUSIONS

A large esophageal varix diameter is strongly associated with subsequent VH. A threshold of <3 and ≥5 mm appears to identify patients with cirrhosis at low and high risk for hemorrhage.

Cardiac resynchronization therapy (CRT) reduces morbidity and mortality among selected patients with left ventricular systolic dysfunction and severe heart failure symptoms despite guideline-directed medical therapy (GDMT). Contemporaneous guidelines provided clear recommendations regarding selection of patients for CRT, including that all patients should first receive GDMT with β blockers and renin-angiotensin axis antagonists. Prevalence of GDMT among real-world patients receiving CRT defibrillators (CRT-D) has not been well studied. We identified 45,392 patients in the National Cardiovascular Data Registry Implantable Cardioverter-Defibrillator Registry who underwent first CRT-D implantation for primary prevention of sudden death from January 2006 to June 2008. We calculated the proportion of patients with contemporaneous class I guideline indications for CRT-D, the proportion receiving GDMT for heart failure, and the proportion receiving GDMT who had class I guideline indications for CRT-D. Among patients without contraindications, 87% were prescribed β blockers, 78% an angiotensin-converting enzyme inhibitor or an angiotensin II receptor inhibitor, and 70% both a β blocker and an angiotensin-converting enzyme or angiotensin II receptor inhibitor at discharge. Finally, 50% of patients met class I guideline indications and were prescribed GDMT at discharge; 9% neither met class I indications nor were prescribed GDMT at discharge. The major limitation of this study is the lack of dosage information in the Implantable Cardioverter-Defibrillator Registry and lack of prescribing information at times other than discharge. In conclusion, many patients receiving CRT-D are not receiving GDMT at discharge. Ensuring that all patients receiving CRT-D are also receiving GDMT appears to be a quality improvement target.

OBJECTIVE

To describe returning veterans' transition experience from military to civilian life and to educate health care providers about culture-centered communication that promotes readjustment to civilian life.

METHODS

Qualitative, in-depth, semi-structured interviews with 17 male and 14 female Iraq and Afghanistan veterans were audio recorded, transcribed verbatim, and analyzed using Grounded Practical Theory.

RESULTS

Veterans described disorientation when returning to civilian life after deployment. Veterans' experiences resulted from an underlying tension between military and civilian identities consistent with reverse culture shock. Participants described challenges and strategies for managing readjustment stress across three domains: intrapersonal, professional/educational, and interpersonal.

CONCLUSIONS

To provide patient-centered care to returning Iraq and Afghanistan veterans, health care providers must be attuned to medical, psychological, and social challenges of the readjustment experience, including reverse culture shock. Culture-centered communication may help veterans integrate positive aspects of military and civilian identities, which may promote full reintegration into civilian life.

PRACTICE IMPLICATIONS

Health care providers may promote culture-centered interactions by asking veterans to reflect about their readjustment experiences. By actively eliciting challenges and helping veterans' to identify possible solutions, health care providers may help veterans integrate military and civilian identities through an increased therapeutic alliance and social support throughout the readjustment process.
