Background Although extrahepatic metastasis occurs rarely after hepatic resection for hepatocellular carcinoma (HCC), the prognosis of
these patients is extremely poor. Predictors of extrahepatic metastasis have not been fully investigated.
Methods To identify predictors of extrahepatic metastasis after resection, we retrospectively investigated 77 patients with HCC tumors
>50 mm in diameter who underwent hepatic resection. We investigated correlations between postoperative extrahepatic metastasis
and clinicopathologic factors as well as extrahepatic metastasis-free survival rate by log rank test and predictors of extrahepatic
metastasis by univariate and multivariate logistic regression models.
Results Hepatitis B surface antigen (HBs-Ag) was found in 25 (32.5%) of 77 patients, and extrahepatic metastasis occurred in 26 (33.8%).
Patients with extrahepatic metastasis showed better liver function and a high occurrence of HBs-Ag positivity than those without.
The 5-year extrahepatic metastasis-free survival rate was worse in patients with HBs-Ag positivity, larger tumors (≥70 mm),
higher alfa-fetoprotein level (≥300 ng/mL), and lower indocyanine green retention rate at 15 minutes (ICGR15) (<15%) than in those without. By univariate logistic regression analysis, HBs-Ag positivity, larger HCC tumor (≥70 mm),
lower ICGR15 (<15%), and lower preoperative lymphocyte count (<1000/mm3) were predictors of extrahepatic metastasis (P < .1). By multivariate analysis, HBs-Ag positivity was an independent predictor of postoperative extrahepatic metastasis
(P = .04).
Conclusions In patients positive for HBs-Ag, radiologic examination of extrahepatic organs should be performed as a part of the postoperative
surveillance. Hepatitis B virus infection may promote establishment of extrahepatic metastasis. 相似文献

Antitubercular 7-substituted 2-nitroimidazo[2,1-b][1,3]oxazines were previously shown to exhibit potent antileishmanial and antitrypanosomal activities, culminating in a new clinical investigational drug for visceral leishmaniasis (DNDI-0690). To offset development risks, we continued to seek further leads with divergent candidate profiles, especially analogues possessing greater aqueous solubility. Starting from an efficacious monoaryl derivative, replacement of the side chain ether linkage by novel amine, amide, and urea functionality was first explored; the former substitution was well-tolerated in vitro and in vivo but elicited marginal alterations to solubility (except through a less stable benzylamine), whereas the latter groups resulted in significant solubility improvements (up to 53-fold) but an antileishmanial potency reduction of at least 10-fold. Ultimately, we discovered that O-carbamate 66 offered a more optimal balance of increased solubility, suitable metabolic stability, excellent oral bioavailability (100%), and strong in vivo efficacy in a visceral leishmaniasis mouse model (97% parasite load reduction at 25 mg/kg). 相似文献

Objective
Closer caregiver-care recipient (CG-CR) relationships are associated with better cognitive and functional abilities, activities of daily living (in persons with dementia), and lower informal care costs.Methods
Due to the difficulty in treating neuropsychiatric symptoms (NPSs) and their detrimental effects on caregivers and care recipients, we examined whether closeness of CG-CR relationships was associated with overall NPS severity or with specific NPS symptom domains in care recipients. In a longitudinal population-based study in Cache County, Utah, the 12-item Neuropsychiatric Inventory (NPI-12) was assessed in 300 CG-CR dyads. Caregivers reported current relationship closeness using the Whitlatch Relationship Closeness Scale. Linear mixed models examined associations between CG-CR closeness and NPI-12 total score or selected symptom domains over time (observation period: 2002–2012).Results
In unadjusted linear mixed models, higher closeness scores were associated with a five-point lower NPI-12 score and a one-point lesser increase in NPI-12 per year. NPI scores also showed lower affective cluster scores (two points) and lesser increase in psychosis cluster (approximately 0.5 points per year) and agitation/aggression (0.16 points per year) for each unit increase in closeness. When controlling for NPI caregiver distress, associations between closeness and NPSs diminished to a 0.5-point lesser increase in total NPI-12 score per year. Adjusted models for NPI domains/clusters showed ?0.32 points per year for the psychosis cluster, ?0.11 points per year for agitation/aggression, and ?0.67 overall for the affective cluster.Conclusion
Higher CG-CR closeness, a potentially modifiable factor, is associated with lower NPS severity and may provide a target for intervention. 相似文献988.

Therapy of the central nervous system (CNS) manifestations of lysosomal storage diseases (LSDs) has remained a major challenge
because of its inability to deliver therapeutic agents efficiently across the intact blood–brain barrier. Non-specific therapies
such as hematopoietic stem cell transplantation have been useful in globoid cell leukodystrophy (Krabbe disease) and in some
mucopolysaccharidoses. Anti-inflammatory agents also show promise as adjuvant therapy. High doses of replacement therapy with
native or modified enzyme show renewed promise for correction of CNS cells. Alternatively, small molecules can enter the brain
relatively easily and promote reduction of accumulated substrate or function as pharmacological chaperones to enhance the
level of the deficient enzyme. Gene therapy is still being developed and tested in patients. It is therefore likely that,
thanks to a better understanding of disease mechanism, a variety of therapeutic approaches, used alone or in combination,
will be useful to treat the devastating neurological complications of LSDs. 相似文献

Robotic surgery has recently started to be used for minimally invasive colorectal surgery. Because of limited access and high
cost, very few colorectal units are available in the US. We describe our experience with benign and malignant disease since
September 2008 in a dedicated colorectal practice. A prospective collected robotic database was queried for colon and rectal
procedures. Anonymized demographic, intraoperative, and postoperative data, and pathology information, were collected and
analyzed. A total of 48 robotic procedures for colorectal maladies were performed in the study period. There were 35 females
and 13 males. The average age was 57 years. Twenty-two cases were performed for diverticulitis, 13 for malignancy (10 distal
rectum (<8 cm anal verge), two rectosigmoid, and one ascending colon cancer), 10 for rectal prolapse, two for rectovaginal
fistula, and one for incidental appendiceal mucocele found during a gynecologic resection. The average operating room time
(OR) was 162 min and there were no conversions to open procedures. Blood loss averaged 104 mL. Mean length of hospital stay
(LOS) was 5.4 days. Patient readmission occurred in 27.3% of cases. The anastamotic leak rate was 2.1% (one patient). No mortalities
were reported. When the analysis was performed for colorectal malignancies (13 procedures), there were nine females and four
males. Average age was 59 years. The mean OR time was 191.1 min. Mean intraoperative blood loss was 123 mL and there were
no conversions to open surgery. Average LOS was 7.0 days. There was one anastamotic leak (7.7%). The length of stay was increased
for the patient with anastamotic leak (18 days) and for a patient with high stoma output and postoperative ileus (17 days).
Readmission rate was 30.1%. The total number of lymph nodes retrieved averaged 19.5, with a mean distal margin of 3.0 cm and
in all cases negative radial margins. Robotic colorectal surgery for benign and malignant disease is safe, and short-term
outcomes are comparable with those of traditional and laparoscopic surgery. Oncologic resections were adequate with excellent
lymph node sampling and radial and distal margins. 相似文献

The present paper tries to honour Charles Darwin's memory in the year in which the world celebrates the 200 anniversary of
his birth and the 150 of the publication of The Origin of Species. After pointing out that the basis of his theory of evolution, “improvement of species”, is a time-dependent concept, commenting
on the role that atrophied organs played in Darwin's work and relating this with Darwinian medicine, it is suggested that
stem cell and cardiovascular therapies could be perhaps connected with some of the ideas and possibilities already envisaged
by Darwin and mentioned in one of his books, The Variation of Animals and Plants under Domestication (1868). 相似文献
