Trajectory of adherence to home rehabilitation among older adults with hip fractures and cognitive impairment

This study aimed to identify different trajectories of adherence to home rehabilitation for older adults with hip fracture and cognitive impairment, to examine associations between different adherence trajectories and postoperative recovery outcomes, and to explore the predictors of adherence trajectories. Group-based trajectory modeling showed two adherence trajectories: low (39.06%) and high (60.94%) adherence. The high adherence group had better activities of daily living (β=11.77, p<.001), instrumental activities of daily living (β=0.56, p<.01), femoral muscular strength (β=3.35, p<.01) on the fractured side and quality of life (β=-0.81, p=.02) than the low adherence group. Participants who established exercise habits (OR=6.49, p<.01) and consulted a physical therapist (OR=4.29, p=.03) during hospitalization were more likely to be in the high adherence group.     

Is rosacea a systemic disease?

Rosacea is a chronic inflammatory facial disease occurring world-wide. The incidence of rosacea is increasing with age, with the clinical course being characterized by relapses. The pathogenesis of rosacea is not completely understood, but neurovascular and immunologic mechanisms are involved. Rosacea has a number of known extrinsic triggers that should be avoided, such as sun exposure, heat and cold, alcoholic beverages, and spicy food. Of greater importance is the observation that rosacea may develop as a manifestation of systemic diseases with a significant morbidity and even mortality. Obesity, Helicobacter pylori infection, smoking, and inflammatory bowel disease bear a significant risk for the development of rosacea. Metabolic, psychiatric, and neurologic disorders and certain types of cancer show a significant association with rosacea. The possible link to cardiovascular events is debatable. There are extrafacial and extracutaneous manifestations of rosacea, such as the red scalp syndrome, ocular rosacea, and migraine. Rosacea should be considered a systemic disease.     

Monosomy of Chromosome 9 Is Associated With Higher Grade,Advanced Stage,and Adverse Outcome in Clear-cell Renal Cell Carcinoma

BackgroundClear-cell renal cell carcinoma (ccRCC) is one of the most common malignancies in humans and is usually associated with poor outcomes. Cancers are considered to be genetic diseases. Therefore, a better understanding of genetic alterations that are related to disease progression or poor prognosis can help to more precisely identify high-risk patients and treat them more effectively. The aim of this study was to examine the frequency of whole chromosome 9 loss (monosomy of chromosome 9) and its prognostic value in patients with ccRCC.Materials and MethodsSingle nucleotide polymorphism-based chromosome microarray (CMA) analysis was performed on 103 resected specimens from patients with ccRCC who had undergone partial or radical nephrectomy between January 2002 and March 2017 at Fox Chase Cancer Center. Monosomy 9 was correlated with clinicopathologic parameters and recurrence-free survival.ResultsChromosome 9 loss was detected in 31 (30%) of 103 tumors. Tumors with chromosome 9 loss had higher histologic grade (3 and 4; P < .001) and pathologic stage (P < .001). In 59 patients with non-metastatic ccRCC, chromosome 9 loss was also associated with higher recurrence rate and shorter recurrence-free survival (RFS) (12-month RFS, 77.8%; 95% confidence interval, 36.5%-93.9% for chromosome 9 loss vs. 95.7%; 95% confidence interval, 84.0%-98.9% for no loss; P = .002).ConclusionsChromosome 9 loss was found in 30% of patients with ccRCC and correlated with higher grade, advanced stage, and shorter RFS in patients with Stage I to III ccRCC.     

荆芥连翘汤对促进皮肤溃疡愈合的影响

目的 观察荆芥连翘汤对小鼠皮肤溃疡的治疗作用。方法 建立小鼠皮肤创伤和烫伤两种皮肤溃疡模型．比较荆芥连翘汤以及rhEGF的用药组和自身对照组小鼠皮肤溃疡面积，用昆微镜观察溃疡面炎症细胞浸润情况。结果 和自身对照组相比，荆芥连翘汤可明显缩小小鼠皮肤溃疡面积（P〈0．001），同时炎症细胞浸润显著减少（P〈0．001）；荆芥连翘汤用药组疗效显著优于rhEGF用药组。结论 荆芥连翘汤可明显促进小鼠皮肤溃疡的愈合。     

An Adrenal Incidentaloma Diagnosed as Dopamine-Secreting Pheochromocytoma: A Case Report

BackgroundDopamine-secreting pheochromocytomas are exceedingly rare.Case presentationA 28-year-old woman, who was admitted due to 4 hours of acute-onset abdominal pain, detected an adrenal mass incidentally. She was almost asymptomatic without a known family history. Laboratory assessments showed significant increases in dopamine levels of serum and 24-h urinary. By using preoperative a-adrenergic receptor blockers, she developed orthostatic hypotension and palpitations. When she underwent laparoscopic left adrenalectomy, she experienced rapid cyclic fluctuations in systolic blood pressure from 90 mmHg to 200 mmHg. Postoperatively, she exhibited prolonged hypotension, requiring vasopressor therapy and fluid replacement. According to histopathological diagnosis, it was a pheochromocytoma. Dopamine levels in 24-h urine and serum decreased to normal after operation. Analysis of specific gene SDHB, SDHD, RET, VHL and NF1 detected no pathogenic mutations.ConclusionPatients with dopamine-secreting pheochromocytomas are mostly asymptomatic, leading to a significant delay in diagnosis. There is a large possibility for dopamine-secreting pheochromocytomas to show a malignant tendency than the adrenergic and noradrenergic phenotypes. The a-adrenergic receptor blocker is not indicated for preoperative medical treatment because it can cause hypotension and cardiovascular failure. Calcium channel blockers or metyrosine may be better alternatives. All patients with pheochromocytomas should receive targeted genetic testing based on specific clinical features. SDHB, SDHD, RET, VHL and NF1 mutations are suggested for genetic testing of adrenal dopamine-secreting pheochromocytomas.
