Comparing human and mouse salivary glands: A practice guide for salivary researchers

Mice are a widely utilized in vivo model for translational salivary gland research but must be used with caution. Specifically, mouse salivary glands are similar in many ways to human salivary glands (i.e., in terms of their anatomy, histology, and physiology) and are both readily available and relatively easy and affordable to maintain. However, there are some significant differences between the two organisms, and by extension, the salivary glands derived from them must be taken into account for translational studies. The current review details pertinent similarities and differences between human and mouse salivary glands and offers practical guidelines for using both for research purposes.     

Decompensated cirrhosis-related admissions in a large urban hospital in Uganda: prevalence,clinical and laboratory features and implications for planning patient management

Background

Cirrhosis-related complications are a major cause of morbidity and mortality in areas where its risk factors are endemic.

Objective

We determined the prevalence of decompensated cirrhosis among patients on the gastroenterology service of Mulago Hospital and described the clinical and laboratory features of these patients.

Methods

All patients admitted to the unit were assessed and their diagnosis documented. Patients with cirrhosis had clinical features of decompensation recorded. History of alcohol consumption was taken and testing for hepatitis B surface antigen (HBsAg) and hepatitis C antibody (anti-HCV) performed.

Results

Between September 2010 and January 2011, we enrolled 482 patients. The majority (53.7%) were male, overall median age 38 years. Decompensated cirrhosis was diagnosed in 85 (17.6%) patients. Of the 85 patients, 47 (55.3%) gave a history of alcohol intake, HBsAg was positive in 23 (27.1%) and anti-HCV in 3 (3.5%). Decompensation was defined by ascites among 81 (95.3%) patients, variceal bleeding in 31 (36.5%), encephalopathy in 20 (23.5%).

Conclusion

Cirrhosis is common in Mulago hospital presenting mainly with ascites and variceal bleeding. Aside from controlling causes of liver diseases, especially alcohol and hepatitis B virus infection, in the interim it is necessary to manage complications in patients who already have cirrhosis.     

Comparison of Health Status and Quality of Life of Related Versus Paid Unrelated Living Kidney Donors

The aim of this cross‐sectional study was to assess the health status and quality of life (QOL) of paid unrelated versus related living kidney donors postdonation at Shiraz Transplant Center in Iran. We invited all donors (n = 580, 347 paid unrelated, 233 related) who underwent donor nephrectomy at our center from 2004 to 2010 to participate in a health survey and physical examination. Of 580 donors, 144 consented to participate; participation of paid unrelated donors was significantly lower than related (52/347 vs. 92/233; p < 0.001). Participants underwent a complete physical examination, QOL assessment (using a 36‐item short form health survey [SF‐36] questionnaire) and laboratory work‐up. The paid unrelated donors compared with related donors were younger (34.2 ± 7.2 vs. 40.7 ± 9.7 years, p < 0.001), had shorter time since donation (2.9 ± 1.6 vs. 3.8 ± 2 years, p = 0.004), had higher estimated GFR (72.6 ± 22 vs. 63.8 ± 15.3 mL/min/1.73 m², p = 0.006) and had a higher percentage of patients with microalbuminuria (35% vs. 0%, p < 0.001). Additionally, general health and social functioning scores among paid unrelated donors were significantly lower (p < 0.001 and p = 0.02, respectively) than related donors. Other SF‐36 scores, although lower in paid unrelated donors, did not reach statistical significance. Iranian paid unrelated donors have lower QOL and higher incidence of microalbuminuria compared with related donors.
