Health, Psychological and Demographic Predictors of Depression in People with Fibromyalgia and Osteoarthritis.

Depression is common in people with fibromyalgia (FM) and osteoarthritis (OA) and has been linked to adverse health outcomes in these conditions. The purpose of this study was to examine differences in predictors of depression among individuals with FM and OA using a range of health, demographic, and psychological variables. Of the total 963 participants, 600 were diagnosed with FM, and 363 with OA. The Quality of Well-Being Scale (QWB) was used to assess health status. The Fibromyalgia Impact Questionnaire (FIQ) and the Arthritis Impact Measurement Scale (AIMS) were used to measure disease-specific impact. Additionally, participants completed self-efficacy and helplessness assessments. Depression was measured using the Center for Epidemiological Studies Scale (CES-D). The results of a moderated linear regression showed that higher depression scores were associated with lower health status and a greater condition impact, especially in the FM group. Self-efficacy and helplessness predicted depression in both groups, but more strongly in FM. White participants with OA were more depressed than their non-White counterparts, while the opposite was true for FM. These findings indicate that improving health status and psychological well-being might alleviate depression in both FM and OA.

Cardiorespiratory fitness and short-term complications after bariatric surgery.

BACKGROUND: Morbid obesity is associated with reduced functional capacity, multiple comorbidities, and higher overall mortality. The relationship between complications after bariatric surgery and preoperative cardiorespiratory fitness has not been previously studied. METHODS: We evaluated cardiorespiratory fitness in 109 patients with morbid obesity prior to laparoscopic Roux-en-Y gastric bypass surgery. Charts were abstracted using a case report form by reviewers blinded to the cardiorespiratory evaluation results. RESULTS: The mean age (+/- SD) was 46.0 +/- 10.4 years, and 82 patients (75.2%) were female. The mean body mass index (BMI) was 48.7 +/- 7.2 (range, 36.0 to 90.0 kg/m(2)). The composite complication rate, defined as death, unstable angina, myocardial infarction, venous thromboembolism, renal failure, or stroke, occurred in 6 of 37 patients (16.6%) and 2 of 72 patients (2.8%) with peak oxygen consumption (Vo(2)) levels < 15.8 mL/kg/min or > 15.8 mL/kg/min (lowest tertile), respectively (p = 0.02). Hospital lengths of stay and 30-day readmission rates were highest in the lowest tertile of peak Vo(2) (p = 0.005). There were no complications in those with BMI < 45 kg/m(2) or peak Vo(2) > or= 15.8 mL/kg/min. Multivariate analysis adjusting for age and gender found peak Vo(2) was a significant predictor of complications: odds ratio, 1.61 (per unit decrease); 95% confidence interval, 1.19 to 2.18 (p = 0.002). CONCLUSIONS: Reduced cardiorespiratory fitness levels were associated with increased, short-term complications after bariatric surgery. Cardiorespiratory fitness should be optimized prior to bariatric surgery to potentially reduce postoperative complications.

Carbon dioxide laser ablation of perianal fistulas in patients with Crohn's disease: experience with 27 patients.

BACKGROUND: Perianal fistula disease (PAD) occurs in up to 40% of patients with Crohn's disease (CD). Medical therapy is often unsuccessful, and, with surgical therapy, healing is unreliable and management is frequently painful and unsatisfactory. Outpatient CO(2) laser ablation of PAD has emerged as an alternative. METHODS: Twenty-seven patients were evaluated by chart review. The severity of PAD based on a 5 category scoring system was collected. Scores were recorded at the time of surgery and at each subsequent postoperative visit. RESULTS: Differences between PAF severity scores were significant for the initial operation versus postoperative visit 1 (P < .001) and for the initial operation versus the final visit (P < .001). Variation in the postoperative PAD score was affected by the score in the operating room and colonic involvement of CD. CONCLUSION: CO(2) laser ablation therapy successfully treats PAD; many fistulas are completely healed and others are converted into a single, minimally draining fistula with this well-tolerated outpatient procedure.

Laparoscopic sleeve gastrectomy for morbid obesity.

The epidemic of obesity in the United States is a major public health issue and more than a third of adults are now considered obese (body mass index > or = 30 kg/m(2)). Surgery for morbid obesity, bariatric surgery, is the most durable treatment for this disease and about 140,000 cases are performed annually. Laparoscopic sleeve gastrectomy (LSG) has been advocated as the first of a 2-stage procedure for the high-risk, super-obese patient. More recently, LSG has been studied as a single-stage procedure for weight loss in the morbidly obese. LSG has been shown in initial studies to produce excellent excess weight loss comparable with laparoscopic Roux-en-Y gastric bypass in many series with a very low incidence of major complications and death. We describe our technique for LSG.

Vascular endothelial growth factor-165 gene therapy promotes cardiomyogenesis in reperfused myocardial infarction.

BACKGROUND: Vascular endothelial growth factor (VEGF)-165 promotes cardiomyogenesis in chronic myocardial ischemia and nonreperfused myocardial infarction (MI). It is unknown whether this effect is present in reperfused MI. We sought to investigate the effect of VEGF-165 gene therapy on cardiomyogenesis after reperfused MI. METHODS AND RESULTS: Twenty-four Yucatan minipigs underwent thoracotomy and a vascular clamp was placed in the left circumflex artery. Reperfusion was reestablished after 90 minutes, and VEGF-165 gene therapy or placebo was administered. A replication-deficient recombinant human adenovirus serotype 5 was used for gene transfer (Ad5-VEGF165). The same viral vector devoid of VEGF gene (Ad5-beta-galactosidase) was used as placebo. Two administration routes were tested, intramyocardial (IM) injection and circumflex intracoronary (IC) infusion. The pigs were assigned to one of the following groups: IM Ad5-VEGF165 (n = 6), IM Ad5-betaGal (n = 6), IC Ad5-VEGF165 (n = 6), and IC Ad5-betaGal (n = 6). All pigs received 5-bromo-2'-deoxyuridine (BrdU) 250 mg IV twice a week to label cells undergoing DNA replication. The hearts were explanted at 4 weeks. BrdU-labeled cardiomyocytes in the peri-infarct area were counted by a pathologist blinded to group assignment. The number of BrdU-labeled cardiomyocytes per million cells was 4-fold higher in the group receiving IM VEGF-165 (64 +/- 11.4) vs. IM placebo (16 +/- 10.6), P = 0.034. No difference in infarct size or ventricular function was observed between the groups. CONCLUSIONS: IM VEGF-165 gene therapy promotes cardiomyogenesis in reperfused MI. However, no benefit in infarct size or cardiac function was observed at 4 weeks. The origin of these cells remains unknown and needs to be determined.

Inguinal herniation of a transplant ureter: rare cause of obstructive uropathy.

We present a rare case of late renal allograft failure from ureteral obstruction resulting from inguinal herniation. A 72-year-old man presented with an elevated creatinine and hydroureteronephrosis of a transplanted kidney on ultrasound. Noncontrast computed tomography demonstrated an inguinal hernia containing ureter, and a nephrostomy tube was placed. The hernia and ureter were temporarily reduced during antegrade stent insertion. Creatinine normalized and we performed inguinal herniorrhaphy with polypropylene mesh. The ureter was not reimplanted. Renal function remained stable after nephrostomy tube removal. Simple herniorrhaphy without ureteral reimplantation may fix the case of ureteral obstruction from inguinal herniation.
