Age matters: a study of clinical and economic outcomes following cholecystectomy in elderly Americans

Background

Gallstone disease increases with age. The aims of this study were to measure short-term outcomes from cholecystectomy in hospitalized elderly patients, assess the effect of age, and identify predictors of outcomes.

Methods

This was a cross-sectional analysis, using the Health Care Utilization Project Nationwide Inpatient Sample (1999–2006), of elderly patients (aged 65–79 and ≥80 years) and a comparison group (aged 50–64 years) hospitalized for cholecystectomy. Linear and logistic regression models were used to evaluate age and outcome relationships. Main outcomes were in-hospital mortality, complications, discharge disposition, mean length of stay, and cost.

Results

A total of 149,855 patients aged 65 to 79 years, 62,561 patients aged ≥ 80 years, and 145,675 subjects aged 50 to 64 years were included. Elderly patients had multiple biliary diagnoses and longer times to surgery from admission and underwent more open procedures. Patients aged 65 to 79 years and those aged ≥80 years had higher adjusted odds of mortality (odds ratios [ORs], 2.36 and 5.91, respectively), complications (ORs, 1.57 and 2.39), nonroutine discharge (ORs, 3.02 and 10.76), longer length of stay (ORs, 1.11 and 1.31), and higher cost (ORs, 1.09 and 1.22) than younger patients.

Conclusions

Elderly patients undergoing inpatient cholecystectomy have complex disease, with worse outcomes. Longer time from admission to surgery predicts poor outcome.     

Association between inflammatory bowel disease and prostate cancer: A large-scale,prospective, population-based study

Inflammatory bowel disease (IBD) is an established risk factor for colorectal cancer. Recent reports suggesting IBD is also a risk factor for prostate cancer (PC) require further investigation. We studied 218 084 men in the population-based UK Biobank cohort, aged 40 to 69 at study entry between 2006 and 2010, with follow-up through mid-2015. We assessed the association between IBD and subsequent PC using multivariable Cox regression analyses, adjusting for age at assessment, ethnic group, UK region, smoking status, alcohol drinking frequency, body mass index, Townsend Deprivation Index, family history of PC and previous prostate-specific antigen testing. Mean age at study entry was 56 years, 94% of the men were white, and 1.1% (n = 2311) had a diagnosis of IBD. After a median follow-up of 78 months, men with IBD had an increased risk of PC (adjusted hazard ratio [aHR] = 1.31, 95% confidence interval [CI] = 1.03-1.67, P = .029). The association with PC was only among men with the ulcerative colitis (UC; aHR = 1.47, 95% CI = 1.11-1.95, P = .0070), and not Crohn's disease (aHR 1.06, 95% CI = 0.63-1.80, P = .82). Results are limited by lack of data on frequency of health care interactions. In a large-scale, prospective cohort study, we detected an association between IBD, and UC specifically, with incident PC diagnosis.     

Predictors of Short Intensive Care Unit Stay for Patients with Diabetic Ketoacidosis Using a Novel Emergency Department–Based Resuscitation and Critical Care Unit

Background

The resuscitation and critical care unit is a novel emergency department–intensive care unit designed to provide early critical care to emergency department patients for ≤24 h.

Positive HLA‐B27 and sacroiliitis is not always spondyloarthritis

A 36‐year‐old man was treated for several years with multiple agents for ankylosing spondylitis based on positive human leukocyte antigen‐B27 and sacroiliitis. He was also diagnosed with osteoporosis and hypophosphatemia. Over these years, from being an avid runner, he became dependent on a walker for ambulation. The lack of treatment response and the low phosphorus were clues that eventually led to a diagnosis of tumor‐induced osteomalacia. This case discusses the importance of not solely relying on genetic markers and sacroiliitis for diagnosing ankylosing spondylitis as other conditions can cause similar presentations.     

Forearm fracture dislocations

Foerearm stability is provided by a complex interplay of the bony and osseo-ligamentous structures which constitute the forearm unit. Consequently, fractures of the radius and/or ulna with concurrent injuries to the stabilizing ligamentous structures can lead to chronic instability and dysfunction if treated incorrectly. Seen in both the adult and paediatric populations, correct diagnosis and management are essential to prevent long-term forearm pain and instability. This article covers the three main instability pattern injuries of the forearm with a focus on anatomy, biomechanics and surgical principles of acute and chronic reconstruction.
