Objective: The aim of the trial was to compare laparoscopic technique with open technique regarding short-term pain, quality of life (QoL), recovery, and complications. Background: Laparoscopic and open techniques for incisional hernia repair are recognized treatment options with pros and cons. Methods: Patients from 7 centers with a midline incisional hernia of a maximum width of 10 cm were randomized to either laparoscopic (LR) or open sublay (OR) mesh repair. Primary end point was pain at 3 weeks, measured as the bodily pain subscale of Short Form-36 (SF-36). Secondary end points were complications registered by type and severity (the Clavien-Dindo classification), movement restrictions, fatigue, time to full recovery, and QoL up to 8 weeks. Results: Patients were recruited between October 2005 and November 2009. Of 157 randomized patients, 133 received intervention: 64 LR and 69 OR. Measurements of pain did not differ, nor did movement restriction and postoperative fatigue. SF-36 subscales favored the LR group: physical function (P<0.001), role physical (P<0.012),mental health (P<0.022), and physical composite score (P < 0.009). Surgical site infections were 17 in the OR group compared with 1 in the LR group (P < 0.001). The severity of complications did not differ between the groups (P < 0.213). Conclusions: Postoperative pain or recovery at 3 weeks after repair of midline incisional hernias does not differ between LR and OR, but the LR results in better physical function and less surgical site infections than the OR does.

Isotonic saline is a widely-used infusion fluid, although the associated chloride load may cause metabolic acidosis and impair kidney function in young, healthy volunteers. We wished to examine whether these effects also occurred in the elderly, and conducted a crossover study in 13 men with a mean age of 73 years (range 66-84), who each received intravenous infusions of 1.5 l of Ringer's acetate and of isotonic saline. Isotonic saline induced mild changes in plasma sodium (mean +1.5 mmol.l-1), plasma chloride (+3 mmol.l-1) and standard bicarbonate (-2 mmol.l-1). Three hours after starting the infusions, 68% of the Ringer's acetate and 30% of the infused saline had been excreted (p < 0.01). The glomerular filtration rate increased in response to both fluids, but more after the Ringer's acetate (p < 0.03). Pre-infusion fluid retention, as evidenced by high urinary osmolality (> 700 mOsmol.kg-1) and/or creatinine (> 7 mmol.l-1), was a strong factor governing the responses to both fluid loads. © 2015 The Association of Anaesthetists of Great Britain and Ireland.

Aims/hypothesis: The aim of this study was to determine whether the mean size of fat cells in either visceral or subcutaneous adipose tissue has an impact on the metabolic and inflammatory profiles in morbid obesity. Methods: In 80 morbidly obese women, mean visceral (omental) and subcutaneous fat cell sizes were related to in vivo markers of inflammation, glucose metabolism and lipid metabolism. Results: Visceral, but not subcutaneous, adipocyte size was significantly associated with plasma apolipoprotein B, total cholesterol, LDL-cholesterol and triacylglycerols (p ranging from 0.002 to 0.015, partial r ranging from 0.3 to 0.4). Subcutaneous, but not visceral, adipocyte size was significantly associated with plasma insulin and glucose, insulin-induced glucose disposal and insulin sensitivity (p ranging from 0.002 to 0.005, partial r ranging from -0.34 to 0.35). The associations were independent of age, BMI, body fat mass or body fat distribution. Adipose tissue hyperplasia (i.e. many small adipocytes) in both regions was significantly associated with better glucose, insulin and lipid profiles compared with adipose hypertrophy (i.e. few large adipocytes) in any or both regions (p ranging from <0.0001 to 0.04). Circulating inflammatory markers were not associated with fat cell size or corresponding gene expression in the fat cell regions examined. Conclusions/interpretation: In morbidly obese women region-specific variations in mean adipocyte size are associated with metabolic complications but not systemic or adipose inflammation. Large fat cells in the visceral region are linked to dyslipidaemia, whereas large subcutaneous adipocytes are important for glucose and insulin abnormalities. Hyperplasia (many small adipocytes) in both adipose regions may be protective against lipid as well as glucose/insulin abnormalities in obesity. © 2010 Springer-Verlag. Source

Purpose: Urine sampling has previously been evaluated for detecting dehydration in young male athletes. The present study investigated whether urine analysis can serve as a measure of dehydration in men and women of a wide age span. Methods: Urine sampling and body weight measurement were undertaken before and after recreational physical exercise (median time: 90 min) in 57 volunteers age 17-69 years (mean age: 42). Urine analysis included urine color, osmolality, specific gravity, and creatinine. Results: The volunteers' body weight decreased 1.1% (mean) while they exercised. There were strong correlations between all 4 urinary markers of dehydration (r = .73-.84, p < .001). Researchers constructed a composite dehydration index graded from 1 to 6 based on these markers. This index changed from 2.70 before exercising to 3.55 after exercising, which corresponded to dehydration of 1.0% as given by a preliminary reference curve based on 7 previous studies in athletes. Men were slightly dehydrated at baseline (mean: 1.9%) compared with women (mean: 0.7%; p < .001), though age had no influence on the results. A final reference curve that considered both the present results and the 7 previous studies was constructed in which exercise-induced weight loss (x) was predicted by the exponential equation x = 0.20 dehydration index1.86. Conclusion: Urine sampling can be used to estimate weight loss due to dehydration in adults up to age 70. A robust dehydration index based on four indicators reduces the influence of confounders. © 2013 Human Kinetics, Inc. Source

In a prospective, randomized clinical study 77 women were assigned randomly to receive sequential hormone therapy with either conventional oral conjugated equine estrogens (0.625 mg) with the addition on 14 of the 28 days of oral medroxyprogesterone acetate (5 mg) or natural E 2 gel (1.5 mg) with oral micronized P (200 mg) on 14 of the 28 days of each cycle. Because oral conjugated equine estrogens-medroxyprogesterone acetate induced a highly significant increase in breast cell proliferation in contrast to percutaneous E 2-oral P with a difference between therapies approaching significance, the former therapy has a marked impact on the breast whereas natural percutaneous E 2-oral micronized P has not. ©2011 by American Society for Reproductive Medicine.
