Insulin sensitivity, body composition and adipose depots following 12 w combined endurance and strength training in dysglycemic and normoglycemic sedentary men.

CONTEXT: Insulin resistance and dysglycemia are associated with physical inactivity and adiposity, and may be improved by exercise. OBJECTIVE: Investigate the effect of exercise on insulin sensitivity, body composition and adipose depots in sedentary men with (n = 11) or without (n = 11) overweight and dysglycemia. MATERIAL AND METHODS: Euglycemic-hyperinsulinemic clamp, ankle-to-neck MRI, MRS, muscle and adipose tissue biopsies before and after 12 weeks combined strength and endurance exercise. RESULTS: Insulin sensitivity, VO2max, strength, whole-body and muscle fat content, and abdominal adipose depots were improved without obvious differences between normo- and dysglycemic men. Hepatic fat, waist circumference and subcutaneous adipose tissue were reduced in the dysglycemic group. For both groups plasma adiponectin was reduced, whereas IL-6 was unchanged. Visceral fat was preferentially lost compared with other adipose depots. DISCUSSION AND CONCLUSION: Body composition, fat distribution and insulin sensitivity improved following training in sedentary middle-aged men with and without dysglycemia.

Uterine artery embolization versus laparoscopic occlusion of uterine arteries for leiomyomas: long-term results of a randomized comparative trial.

PURPOSE: To compare long-term symptom recurrence and 6-month magnetic resonance (MR) imaging results after two different treatments for uterine leiomyomas. MATERIALS AND METHODS: Sixty-six women with uterine leiomyomas were randomized to undergo uterine artery embolization (UAE) or laparoscopic bilateral occlusion of uterine arteries. Contrast-enhanced MR imaging was performed before treatment and after 6 months. RESULTS: Fifty-eight patients received treatment. Median follow-up time was 48 months (range, 8-73 months). Clinical failure and symptom recurrence occurred in 14 patients after laparoscopy (48%) and in five after UAE (17%; P = .02, log-rank test). Hysterectomy was performed in two patients after UAE (7%) and in eight after laparoscopy (28%; P = .041). Six-month MR imaging results were available for 26 patients treated with UAE and 22 treated with laparoscopy. The mean uterine volume was reduced by 51% (range, 16%-86%) after UAE treatment, compared with 33% (range, 6%-77%) after laparoscopy (P = .001). Complete leiomyoma infarction was seen in all 26 patients in the UAE group and in only five patients in the laparoscopy group (P < .001). Eleven patients experienced symptom recurrence later than 6 months. Uterine volume reduction at 6 months was 24% in this group, compared with 48% in the 37 patients with no recurrence (P = .004). Incomplete infarction of leiomyomas was seen in eight of the 11 cases of recurrence (73%) versus nine of 37 cases without recurrence (24%; P = .009). CONCLUSIONS: Recurrence rate was significantly lower after UAE than after laparoscopic treatment. Larger volume reduction and more complete devascularization of leiomyomas were found after UAE treatment and among patients with no recurrence.

Survival and complications after insertion of self-expandable metal stents for malignant oesophageal stenosis.

OBJECTIVE: To report on survival and complications after insertion of self-expandable stents in patients with malignant oesophageal stenosis. MATERIAL AND METHODS: Data were gathered retrospectively from the medical records of 92 consecutive patients in the period 1994-2003. The study comprised 68 men and 24 women (median age 72 years, range 46-93 years) with stenosis from cancer of the oesophagus (n=61), the gastric cardia (n=26) and the lung (n=5), located mainly above (n=4) or below (n=62) the carina, or at the gastro-oesophageal junction (n=26). One uncovered stent and six different covered stents were used. RESULTS: Median and mean survival times after stenting (n=92) were 83 (range 4-1102) and 125 days, respectively. Thirty-day mortality was 19% (n=17), and 7% (n=6) survived more than one year. Survival was neither significantly influenced by division of the patients into diagnostic subgroups nor by comparison of the three most frequently used stents. One, two, three and four stents were received by 76, 11, 4 and 1 patient(s), respectively. There was no stent-related mortality, and complications were bleeding 1 (1%), stent migration 7 (8%), recurrent stenosis 8 (9%) from both tumour overgrowth (n=8) and tumour ingrowth (n=2) when using uncovered stents. Thirteen (14%) patients were re-stented because of recurrent stenosis (n=8) including fistula formation to the left main bronchus (n=2) and stent migration (n=5). CONCLUSIONS: Use of self-expandable stents in patients with inoperable malignant oesophageal stenosis carried few complications and resulted in relatively long survival in comparison with similar studies.

[Surgery and stenting for oesophageal cancer]. / Kirurgi og stenting for cancer oesophagi.

BACKGROUND: The purpose of this study was to evaluate the results of surgery and stenting for operable and inoperable oesophageal cancer. MATERIAL AND METHODS: Retrospective patient materials with resection (n = 65, 1983-2002) or stenting (n = 59, 1994-2003) for primary oesophageal cancer. RESULTS: Mortality after surgery was 11% and 15% of the patients were re-operated. 36 (55%) had complications such as respiratory failure (n = 33), anastomotic dehiscence/perforation (n = 4), chylothorax (n = 1), haemorrhage (n = 3), wound rupture (n = 1), septicaemia (n = 2), arrhythmia (n = 4) and wound infection (n = 5). Median survival after surgery was 11 months. Survival after three years was 17%, after five years 8%. The stent procedure was without mortality but haemorrhage (n = 1) and stent dislocation (n = 2) occurred. 8 patients (14%) were re-stented for tumour stenosis (n = 6), fistula (n = 2) and dislocation (n = 1). Median survival after stenting was 78 days. Survival after 30 days was 80%, after one year 7%. INTERPRETATION: Resectable oesophageal cancer should be operated in fit patients, as survival is improved and some patients can be cured. Stenting is the main option in inoperable patients.

Laparoscopic occlusion of uterine vessels for the treatment of symptomatic fibroids: Initial experience and comparison to uterine artery embolization.

OBJECTIVE: Our purpose was to evaluate the effects of laparoscopic occlusion of uterine vessels in treating symptomatic fibroids and compare with embolization of the uterine arteries. STUDY DESIGN: We studied 46 premenopausal women, aged 43 (34-51) years with symptomatic uterine fibroids, undergoing radiologic embolization (n=24) and laparoscopy closure of the uterine arteries (n=22). RESULTS: The laparoscopic technique reduced picture blood assessment score after 6 months by 50% from an initial value of 345 (+/-288). Uterus volume was reduced by 37% (+/-18%), and the dominant fibroid was reduced by 36% (+/-31%). Postoperative pain and use of pain relief differed significantly, requiring more pain medication after embolization: ketobemidon 38 mg compared with 16 mg in the laparoscopic group (P=.008). Specific complications to the laparoscopic technique were temporary damage to the obturator nerve in three patients. CONCLUSION: Laparoscopic occlusion of uterine vessels is a promising new method for treating fibroid-related symptoms, with less postoperative pain than embolization and comparable effects on symptoms.
