The purpose of this study was to evaluate the outcome of subcoracoid pectoralis major transfer for the treatment of irreparable
anterosuperior rotator cuff tears. This type of tear involves complete rupture of the subscapularis in combination with either
the supraspinatus alone or the supraspinatus and infraspinatus. These ruptures are characterised by a poor quality of the
rotator cuff that does not allow for a direct tendon-to-bone reconstruction. Between 2000 and 2006, 15 patients were treated
using a deltopectoral approach and transfer of the clavicular part of the pectoralis major to the lesser tuberosity and to
the anterior part of the greater tuberosity. After an average follow-up (follow-up rate 100%) of 37 months the average functional
rating using the Constant and Murley score (CS) increased from 51.73 ± 16.18 to 68.17 ± 8.84 points (p = 0.005). The mean subcategories of the Constant score for pain (p = 0.005), activities of daily living (p = 0.008) but not for range of motion (p = 0.9), significantly improved. At follow-up 13 patients (87%) were available for magnetic resonance imaging (MRI) of the
shoulder. Nine patients (70%) had an intact transferred pectoralis major muscle, two (15%) had one that was thin but intact
and two patients a rupture (one complete). Two patients had postoperative haematoma and one patient developed cuff tear arthropathy.
The good results confirm that pectoralis major transfer is a reliable treatment option for irreparable anterosuperior rotator
cuff injuries with significant improvement in pain and function. 相似文献

Aims/hypothesis Leptin, an adipocyte-secreted hormone, plays an important role in regulating neuroendocrine and immune function as well as
insulin resistance and metabolism. Our objective was to examine the relationship between leptin levels and cardiovascular
morbidity and overall mortality in women with type 2 diabetes.
Subjects and methods This prospective cohort study included 1,194 women with a confirmed diagnosis of type 2 diabetes, who provided a blood sample
at baseline in 1989–1990. Participants were followed for 12 years for the development of health outcomes including cardiovascular
disease (CVD) events as well as total mortality.
Results There were 218 new CVD events and 228 deaths from all causes. Cox proportional hazards analysis was used to estimate the relative
risks (RRs) for each quintile level of leptin compared with the lowest quintile. Leptin levels were positively associated
with several CVD risk factors including BMI and inflammatory markers, but were not independently associated with the incidence
of CVD or total mortality in women with diabetes. The multivariate RRs (95% CIs) for CVD across the quintiles of leptin were
0.96 (0.61–1.53), 0.99 (0.61–1.61), 1.04 (0.63–1.71), 1.02 (0.59–1.75) (p for trend = 0.83).
Conclusions/interpretation Although circulating leptin levels are associated with obesity and inflammatory markers, they are not significantly related
to the risk of CVD or mortality in women with diabetes. 相似文献

BACKGROUND: Obesity is a major risk factor for breast cancer. We hypothesized that obesity-induced decreases in total and/or high-molecular-weight (HMW) adiponectin levels may underlie this association. METHODS: We measured serum total and HMW adiponectin in a hospital-based case-control study of 74 female breast cancer patients and 76 controls. In parallel, expression of adiponectin and its receptors AdipoR1/R2 were measured in tissue samples using RT-PCR, and protein expression of AdipoR1/R2 was localized and quantified using immunohistochemistry. Finally, we documented AdipoR1/R2 expression in several breast cancer cell lines and studied adiponectin signaling and the effect of adiponectin on proliferation in the T47D breast cancer cell line in vitro. RESULTS: Women with the highest adiponectin levels had a 65% reduced risk of breast cancer (P = 0.04). This association became stronger after adjustment for age, body mass index, and hormonal and reproductive factors (P = 0.02). Modeling HMW instead of total adiponectin produced similar results and did not offer any additional predictive value. Breast cancer cells expressed AdipoR1/R2 but not adiponectin. Expression of AdipoR1, but not AdipoR2, was higher in tumor tissue than both adjacent and control tissues. Exposure of T47D cells to adiponectin significantly inhibited the percentage of viable cells to 86% and proliferation to 66% but had no effect on apoptosis. These effects were associated with activation of ERK1/2 but not AMP-activated protein kinase or p38MAPK. CONCLUSION: These studies suggest that adiponectin may act as a biomarker of carcinogenesis and may constitute a molecular link between obesity and breast cancer. 相似文献

OBJECTIVE: Several components of the GH and IGF systems have been implicated in the development of malignancies. All components of these hormonal systems have never been jointly evaluated in female breast cancer, and previous studies have not examined the role of IGF-binding proteins (IGFBP-4, IGFBP-6) or GH-binding protein (GHBP). DESIGN: Hospital-based case-control study. METHODS: In this sample of primarily postmenopausal women, we obtained serum measures of IGF-I, IGF-II, and binding proteins IGFBP-1, IGFBP-3, IGFBP-4, IGFBP-6, as well as GHBP, insulin, and leptin from 74 breast cancer cases and 76 control subjects. RESULTS: In crude analyses, we found lower age-standardized mean IGF-I, IGFBP-3, IGFBP-4, IGFBP-6, and higher IGFBP-1 and GHBP in breast cancer cases when compared with controls. Multivariate models mutually adjusted for other GH-IGF system components and classical breast cancer risk factors demonstrated an inverse association between IGFBP-3 and risk of breast cancer (odds ratio (OR) = 0.2, P < 0.01) and a direct association between GHBP and disease risk (OR = 3.3, P < 0.01). No significant associations were detected in multivariate analyses among IGF-I, IGF-II or IGFBP-1, IGFBP-4, IGFBP-6 with risk of breast cancer, indicating that these factors may not have effects independent of and/or comparable with IGFBP-3 and GHBP. CONCLUSIONS: These results support a protective role of IGFBP-3 and demonstrate for the first time an increased risk of breast cancer with higher GHBP, after accounting for variation in IGFs, IGFBPs, and classical breast cancer risk factors. 相似文献

Objective: The aim of this study was to evaluate the health-related quality of life in survivors of endometrial cancer (EC), and to identify common problems that they may encounter, in the hope of paving the way to improving their quality of life. Study design: We investigated and compared the health conditions and quality of life between EC survivors and the general population as a control group. There were 61 EC patients who were at clinical stage I–III and survived for 5–7 years after the primary treatments. The control group was composed of 527 healthy postmenopausal women. All of them completed a self-evaluated questionnaire pertaining to personal conditions, medical surveillance, individual well-being and quality of life. Results: The EC survivors were divided into two groups: an older group (n=34) and a younger group (n=27). The latter was compared with the controls. In general, most of the EC survivors were old, low-educated women. The majority of them were in a poor condition. They were inactive, received medical surveillance and had regular medication. The distribution of various complications was higher in the older EC group while the climacteric symptoms were more common in the younger EC group. In both EC groups, the quality of life was lower than in the controls. The prevalence of somatic symptoms was higher in the older EC survivors and psychological problems were a common complaint of the younger EC survivors. Conclusion: The quality of life was poor in the EC survivors. To improve their life quality, earlier psychological counseling should be offered to EC survivors, in particular to younger and single women, and hormone replacement therapy (HRT) should be recommended, but on a selective basis, to those patients at low risk of cancer recurrence. 相似文献

Summary In cats without general anaesthesia electric stimulation of the optic chiasma evoked usually in the depth of the cerebellar cortex of lobuli VI and VII a sequence of waves at a latency of 7–10 msec which have been shown to be due to the mossy fibre input. A later wave at a latency of 18–20 msec was also sometimes found in isolation or in association with the early wave. This later field has been identified as due to the climbing fibre input. Unitary recordings have given support to this interpretation. Some correlation has been made with recordings obtained by electric stimulation of the superior colliculus and by flash stimulation of the retinae.It is concluded that the optic pathways project to the visual area of the cerebellar cortex through both mossy and climbing fibre inputs, although from this study based mainly on the laminar analysis of evoked fields, the former input seems to be more widespread and more consistently obtained than the latter.Ibro/Unesco Fellow.Post-graduate student of the Scuola Normale Superiore of Pisa. 相似文献
