Scientific management in nursing students: A concept evaluation.
Periprosthetic seroma is a rare complication of femoropopliteal bypass grafting. Periprosthetic seroma can be defined as the collection of non-infected serous fluid around a prosthetic arterial graft. There is a dearth of literature on how to manage periprosthetic seroma occurrence after femoropopliteal bypass especially in patients whose symptoms do not improve with typical conservative measures.
This report highlights the case of a 70-year-old patient who had a femoropopliteal bypass using a 6 mm Propaten graft for peripheral arterial disease. The patient subsequently presented with leg edema. Leg ultrasound and computed tomography arteriogram showed a periprosthetic seroma with a patent graft. Patient was initially managed conservatively and semi-conservatively and ultimately with aggressive therapy utilizing exploration and surgical resection of the seroma capsule.

Only surgical resection of the seroma capsule produced definitive resolution of the seroma and symptoms. Thigh exploration and surgical resection can be considered as part of the management modalities of periprosthetic seroma occurring after femoropopliteal bypass especially in patients who do not respond to typical conservative measures such as elevation, compression stockings, and diuretics.

Arterial stiffness is associated with major adverse cardiovascular events. The aim of this study is to investigate arterial stiffness by cardio-ankle vascular index (CAVI) in patients with abdominal aortic aneurysm (AAA).

This observational and cross-sectional study involved 59 subjects with AAA and 32 healthy subjects. All subjects underwent ultrasonography examination. CAVI was measured by VaSera-1000 CAVI instrument.

Mean abdominal aortic diameter of AAA patients and controls were 43.88 ± 9.28 mm and 20.43 ± 3.14 mm, consecutively. Baseline clinical characteristics of the patients and controls were similar for age, presence of hypertension, diabetes, dyslipidemia, coronary artery disease and smoking. Left ventricle ejection fraction and Left ventricle mass index (LVMI) were similar between groups. CAVI was significantly higher in patients with AAA than controls (9.74 ± 1.50 vs. 7.60 ± 1.07,
 < 0.001). CAVI was positively correlated with AAA diameter (
 = 0.461,
 < 0.001) and negatively corAA in susceptible patients.Nanoscale size-dependent properties give nanomaterials unique specifications that are robust in many applications of human medicine. Gold nanoparticles (AuNPs) have recently gained attention because of their unique optical, physical and electrical properties. AuNPs increase the efficacy of biomedical applications in diagnostic treatments for infectious diseases, by targeting or labeling target cells/bioactive compounds. However, it is imperative to develop the regimens for more accurate diagnostic tools, preventive care and effective therapy. Our critical and comprehensive review presents emerging avenues of molecular diagnostics as well as therapeutics translated into clinical approaches. This manuscript critically reviews the rampant future of AuNPs in the diagnosis and treatment of the most important diseases, such as cancer and viruses of respiratory system.Epidemiologic studies reported an association between exposure to ambient air pollutants and increased mortality rate attributed to suicide and suicide attempts. The investigation sought to determine whether there is an association between short-term ambient ozone (O3) level exposure and daily hospital admissions for depression in Taipei from 2009 to 2013 using a time-stratified case-crossover design. In our single-pollutant model (with no adjustment for other pollutants), the % increase in daily hospital admissions for depression was 12% on warm days and 30% on cool days, per interquartile range (IQR) rise in O3 levels, respectively. Ozone levels were significantly correlated with daily number of depression admissions both on warm and cool days. In our two-pollutant models, O3 levels remained significant after adjusting for other air pollutants, including particulate matter (PM10, PM2.5), sulfur dioxide (SO2), nitrogen dioxide (NO2), and carbon monoxide (CO) both on warm and cool days. Although O3 levels tended to be higher on warm days, admissions for depression were higher on cool days, suggesting that the relationship between O3 concentrations and depression may be affected by temperature. Further study is needed to better understand these findings.Extant histomorphometric aging methods based on the analysis of the femoral cortex generally report small samples (N less then 100) and highly variable standard error of the estimate (SEE) values (±1.51‒16.98 years). The present paper reviews the published literature on femoral histomorphometry for age-at-death estimation in order to examine the relationship between sample size and SEE values, and makes recommendations for minimum reporting requirements for age-at-death studies based on statistical data. The SEE from a total of 33 studies are analysed. Sample size and confidence intervals are explored using Hennig and Cooper's simulation modelling. Analysis of effect size through a fixed-effect model is performed on 5/33 studies to examine the relationship between sample size and effect size. The pooled sex formulae from Nor et al., Martrille et al. and Thompson and the two sex-specific formulae of Pfeiffer are examined, as they report mean and standard deviation values for both chronological and estimated ages. The results of these analyses support sampling theory, specifically wide variation in SEE when N less then 100, narrowing as the sample size increases, and lower effect sizes in the larger of the five studies examined. The findings provide some support for a minimum threshold of 100‒150 individuals for histomorphometric age-at-death estimation. SBEβCD Analysis of effect size is suggested for future investigation in meta-analyses of forensic anthropological age-estimation studies. To ensure increased precision and meaningful comparison, large samples should be used for histomorphometry, and authors should report SEE and discrete statistics (e.g. n, mean, standard deviation) for both chronological age and estimated age.
