Genetically determined prospect to become long-lived is associated with less abdominal fat and in particular less abdominal visceral fat in men.

PURPOSE: familial longevity is marked by an exceptionally healthy metabolic profile and low prevalence of cardiometabolic disease observed already at middle age. We aim to investigate whether regional body fat distribution, which has previously shown to be associated with cardiometabolic risk, is different in offspring of long-lived siblings compared with controls. METHODS: our institutional review board approved the study, and all participants (n = 344, average age in years 65.6) gave written informed consent. Offspring (n = 175) of non-agenarian siblings were included. Their partners (n = 169) were enrolled as controls. For abdominal visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) measurements, a single-slice 8.0 mm computed tomography (CT) acquisition was planned at the level of the 5th lumbar vertebra. In addition, participants underwent prospectively electrocardiography-triggered unenhanced volumetric CT of the heart. Abdominal VAT and SAT areas (cm(2)) and epicardial adipose tissue (EAT) volumes (ml) were acquired by semi-automated segmentation techniques. Linear regression analysis was performed adjusting for cardiovascular risk factors. RESULTS: total abdominal fat areas were smaller in male offspring compared with controls (353.0 versus 382.9 cm(2), P = 0.022). The association between low abdominal VAT areas in male offspring (149.7 versus 167.0 cm(2) in controls, P = 0.043) attenuated after additional adjustment for diabetes (P = 0.078). Differences were not observed for females. EAT volumes were similar between offspring of long-lived siblings and controls. CONCLUSION: males who have genetically determined prospect to become long-lived have less abdominal fat and in particular less abdominal VAT compared with controls.

Abdominal Tuberculosis Complicated by Intestinal Perforation.

Although relatively rare, there is an increasing incidence of abdominal tuberculosis (TB) in the developed countries, with the peritoneum being the most common site of involvement. Manifestation of abdominal TB should be considered in patients with relevant clinical symptoms and risk factors, including a history of prior TB infection and residence in or travel to an area where tuberculosis is endemic. We report a case of intestinal tuberculosis with a complicated disease course after the completion of treatment. Persisting abdominal symptoms during or after treatment should raise suspicion of subclinical intestinal obstruction. Early clinical recognition and surgical treatment may avoid poor outcome due to intestinal perforation.

Caseous calcification of the mitral annulus assessed by multimodality imaging.

Physicians may not be familiar with caseous calcification of the mitral annulus. It can therefore easily be mistaken for other conditions including tumors. In the appropriate clinical context, by using multimodality imaging, a correct diagnosis can be made, and patient concern or even unnecessary surgery can be avoided.

An unusual cause of multiple incidental lung nodules.

Cystic or cavitating lung nodules may reflect an additional diagnostic challenge in benign metastasizing leiomyoma. Our case underlines the importance of combining clinical and radiological findings with specific pulmonary pathology consultation.

Computed tomography evaluation of cardiac structure and function.

Computed tomography is a noninvasive imaging modality that can be used for the evaluation of cardiac structure and function. This review provides an overview of established and emerging applications of cardiac computed tomography, including evaluation of left and right ventricular function, ventricular morphology, native and prosthetic valves, and pulmonary and coronary vein anatomy.
