Patient reported outcome measures in women undergoing surgery for urinary incontinence and pelvic organ prolapse in Denmark, 2006–2011

Introduction and hypothesis

The aim of this study was to evaluate the impact of urogynecological surgery on quality of life based on patient reported outcome measures (PROMs).

Methods

Data were retrieved from the Danish Urogynaecological Database. Inclusion criteria were Danish women undergoing surgery for urinary incontinence (UI) or pelvic organ prolapse (POP) from 2006 to 2011. Using frequency of symptoms and a visual analogue scale (VAS) both pre- and postoperatively, their severity of symptoms and quality of life were measured by questionnaires.

Results

During the study period, 20,629 urogynecological procedures were performed. The questionnaires on severity of symptoms and the VAS had been completed both pre- and postoperatively for approximately one third of women undergoing surgery. For UI surgery, 83 % had improved symptoms, 13 % were unchanged, and 4 % had worse symptoms postoperatively. For POP surgery, 80, 17, and 3 % were improved, unchanged, and worsened, respectively. The postoperative bother of symptoms and interference in everyday life evaluated by VAS were significantly reduced for both UI [preoperative median VAS score 9, postoperative median score 1 (p?<?0.001)] and POP [8 preoperatively and 0 postoperatively (p?<?0.001)].

Conclusions

Based on PROMs, surgery for UI and POP is effective in alleviating symptoms associated with UI or POP, and it can improve quality of life in symptomatic women. Pre- and postoperative questionnaires are useful tools in assessing symptomatic outcome measures after surgery.     

Effect of Diabetes on Outcomes in Patients Undergoing Emergent Cholecystectomy for Acute Cholecystitis

Background

The purpose of the present study was to determine the prevalence of diabetes and its effect on surgical outcomes in patients undergoing emergent, in-patient cholecystectomy for acute cholecystitis. Some 8.3 % of the U.S. population has diabetes and this number is projected to rise to 21–33 % by 2050. Diabetes is considered to be associated with a higher incidence of acute cholecystitis; however, its impact on outcomes is unknown.

Methods

The American College of Surgeons National Surgical Quality Improvement Program database was queried to identify all patients with acute cholecystitis who underwent emergent in-patient cholecystectomy from 2004 to 2010. The study population was divided into two groups: diabetics and non-diabetics. Diabetics were further subdivided into those taking oral medication and those on insulin. Demographics, co-morbidities, and wound classification were compared with univariate analysis, and 30-day outcomes were compared with univariate and multivariate analyses.

Results

A total of 5,460 patients met the inclusion criteria. Of these 770 (14.10 %) had a diagnosis of diabetes. Mortality was higher for diabetics than for non-diabetics [4.4 vs 1.4 %, adjusted odds ratio (AOR) (95 % CI): 1.79 (1.09, 2.94), adj-p = 0.022]. Preoperative perforation rates were 25.1 and 13.0 %, respectively [AOR (95 % CI): 1.34 (1.09, 1.65), adj-p = 0.005]. The adjusted risk of cardiovascular events and renal failure was significantly higher for diabetics. Insulin treatment, but not oral medication, was associated with a significant increase in mortality, preoperative perforation, superficial surgical site infection, septic shock, cardiovascular incidents, and renal insufficiency.

Conclusions

In patients undergoing cholecystectomy for acute cholecystitis, diabetes increases the risk of mortality, cardiovascular events, and renal failure. Insulin-treated diabetics have more co-morbidities and poorer outcomes.     

Long-term results of transvaginal/transumbilical versus classical laparoscopic cholecystectomy—an analysis of 88 patients

Introduction

Transvaginal/transumbilical cholecystectomy using rigid instruments (TVC) is an alternative to the traditional laparoscopic technique (LC). Due to a lack of long-term data, the transvaginal approach is still controversial.

Methods

Our first 50 TVC patients and 50 LC patients from the same time period with the same limits according to age, BMI and ASA classification were asked 48 questions 2 years postoperatively (mean) about resuming sexual intercourse, the domains “satisfaction” and “pain” of the German Female Sexual Function Index, resuming everyday life, postoperative abdominal pain, subjective impairment, incisional hernias, satisfaction with the aesthetic result, the overall postoperative result, and others. Postoperative sexual satisfaction and pain were defined as main outcome. Forty-six TVC patients and 42 LC patients answered the questions (36 TVC patients and 25 LC patients could answer the questions about sexual function).

Results

No significant differences were found for postoperative sexual function, change in menorrhea, vaginal discharge and postoperative abdominal pain. TVC patients felt significantly less impaired postoperatively (p?=?0.034). Two patients in the LC group developed a trocar hernia (p?=?0.225). TVC patients could resume everyday life significantly earlier (p?<?0.001) and were significantly more satisfied with the aesthetic (p?<?0.001) and the overall postoperative result (p?=?0.001). Significantly more TVC patients would recommend the applied surgical technique to friends and family (p?<?0.001).

Conclusions

This long-time prospective data acquisition from 88 or, for some data, 61 patients accounts for the safety of TVC, particularly with regard to sexual function. Additionally, it found less postoperative impairment, quicker recovery and improved satisfaction for TVC as compared to LC.     

Hypertriglyceridemia is associated with insulin levels in adult cystic fibrosis patients

BackgroundRecent studies have identified hypertriglyceridemic cystic fibrosis patients (CF-TG). However, whether hypertriglyceridemia is associated with an altered metabolic profile remains unknown.ObjectiveTo characterize CF-TG and determine whether triglycerides (TG) levels are associated with metabolic alterations.Methods210 adult CF subjects from the Montreal Cystic Fibrosis Cohort without known diabetes were included in the analysis. All subjects underwent an OGTT to assess glucose tolerance, insulin secretion (insulin AUC) and insulin sensitivity (Stumvoll index). Fasting lipid profiles, pulmonary function (%FEV₁) and BMI were determined. Hypertriglyceridemia (TG > 1.7 mmol/L) was observed in 20 CF patients. These subjects were matched for age, sex and glucose tolerance category with 20 CF patients (CF-normal-TG) and 20 healthy controls that had TG levels below 1.7 mmol/L. Pearson correlations were performed in the complete study sample (n = 210) to examine the associations between TG levels and other parameters.ResultsThe prevalence of hypertriglyceridemia was 9.5%. Compared to CF-normal-TG, CF-TG subjects displayed significantly higher %FEV_1, insulin AUC (AUC_0–120, AUC_0–30, AUC_30–120), cholesterol levels and a higher ratio of total cholesterol to HDL-cholesterol. Pearson analysis demonstrated that TG levels were associated with BMI, %FEV₁, fasting insulin, insulin AUC_0–120 and AUC_30–120, Stumvoll index, cholesterol levels and the ratio of total cholesterol to HDL-cholesterol. All these correlations remained significant after correction for BMI except %FEV₁.ConclusionTG levels are associated with a mild alteration of the metabolic profile. Whether these changes will increase the long-term risk of CF patients in developing cardiometabolic complications remains to be investigated.     

Localized deferoxamine injection augments vascularity and improves bony union in pathologic fracture healing after radiotherapy

BackgroundMedically based efforts and alternative treatment strategies to prevent or remediate the corrosive effects of radiotherapy on pathologic fracture healing have failed to produce clear and convincing evidence of success. Establishing an effective pharmacologic option to prevent or treat the development of non-unions in this setting could have immense therapeutic potential. Experimental studies have shown that deferoxamine (DFO), an iron-chelating agent, bolsters vascularity and subsequently enhances normal fracture healing when injected locally into a fracture callus in long bone animal models. Since radiotherapy is known to impede angiogenesis, we hypothesized that the pharmacologic addition of DFO would serve to mitigate the effects of radiotherapy on new vessel formation in vitro and in vivo.Materials and MethodsIn vitro investigation of angiogenesis was conducted utilizing HUVEC cells in Matrigel. Endothelial tubule formation assays were divided into four groups: Control, Radiated, Radiated + Low-Dose DFO and Radiated + High-Dose DFO. Tubule formation was quantified microscopically and video recorded for the four groups simultaneously during the experiment. In vivo, three groups of Sprague–Dawley rats underwent external fixator placement and fracture osteotomy of the left mandible. Two groups received pre-operative fractionated radiotherapy, and one of these groups was treated with DFO after fracture repair. After 40 days, the animals were perfused and imaged with micro-CT to calculate vascular radiomorphometrics.ResultsIn vitro, endothelial tubule formation assays demonstrated that DFO mitigated the deleterious effects of radiation on angiogenesis. Further, high-dose DFO cultures appeared to organize within 2 h of incubation and achieved a robust network that was visibly superior to all other experimental groups in an accelerated fashion. In vivo, animals subjected to a human equivalent dose of radiotherapy (HEDR) and left mandibular fracture demonstrated quantifiably diminished μCT metrics of vascular density, as well as a 75% incidence of associated non-unions. The addition of DFO in this setting markedly improved vascularity as demonstrated with 3D angiographic modeling. In addition, we observed an increased incidence of bony unions in the DFO treated group when compared to radiated fractures without treatment (67% vs. 25% respectively).ConclusionOur data suggest that selectively targeting angiogenesis with localized DFO injections is sufficient to remediate the associated severe vascular diminution resulting from a HEDR. Perhaps the most consequential and clinically relevant finding was the ability to reduce the incidence of non-unions in a model where fracture healing was not routinely observed.
