Does nipple preservation in mastectomy improve satisfaction with cosmetic results, psychological adjustment, body image and sexuality?

We investigated the influence of nipple areolar complex (NAC) sparing in mastectomy, on patient satisfaction with cosmetic results, body-image, sexuality and psychological well-being. We developed a specific questionnaire and compared two groups of women who underwent radical mastectomy with immediate breast reconstruction (IBR). Between 2004 and 2006, 310 women with NAC preservation and 143 patients with successive NAC reconstruction were mailed the questionnaire at follow-up 1 year after definitive complete breast reconstruction surgery. 256 questionnaires was available. Our results showed significant differences in favour of the NAC sparing group regarding body image (difficulty in looking at themselves naked and being seen naked by their partners after surgery, P = 0.001 and P = 0.003, respectively); regarding satisfaction with the appearance of the nipple (P < .0001) and with the sensitivity of the nipple (P = 0.001); regarding the feeling of mutilation (P = 0.003). NAC sparing in mastectomy has a positive impact on patient satisfaction, body image and psychological adjustment.

Best choice of central venous insertion site for the prevention of catheter-related complications in adult patients who need cancer therapy: a randomized trial

BACKGROUND

Central venous access is extensively used in oncology, though practical information from randomized trials on the most convenient insertion modality and site is unavailable.

METHODS

Four hundred and three patients eligible for receiving i.v. chemotherapy for solid tumors were randomly assigned to implantation of a single type of port (Bard Port, Bard Inc., Salt Lake City, UT), through a percutaneous landmark access to the internal jugular, a ultrasound (US)-guided access to the subclavian or a surgical cut-down access through the cephalic vein at the deltoid-pectoralis groove. Early and late complications were prospectively recorded until removal of the device, patient's death or ending of the study.

RESULTS

Four hundred and one patients (99.9%) were assessable: 132 with the internal jugular, 136 with the subclavian and 133 with the cephalic vein access. The median follow-up was 356.5 days (range 0-1087). No differences were found for early complication rate in the three groups {internal jugular: 0% [95% confidence interval (CI) 0.0% to 2.7%], subclavian: 0% (95% CI 0.0% to 2.7%), cephalic: 1.5% (95% CI 0.1% to 5.3%)}. US-guided subclavian insertion site had significantly lower failures (e.g. failed attempts to place the catheter in agreement with the original arm of randomization, P = 0.001). Infections occurred in one, three and one patients (internal jugular, subclavian and cephalic access, respectively, P = 0.464), whereas venous thrombosis was observed in 15, 8 and 11 patients (P = 0.272).

CONCLUSIONS

Central venous insertion modality and sites had no impact on either early or late complication rates, but US-guided subclavian insertion showed the lowest proportion of failures.

Iron and other metals in neuromelanin, substantia nigra, and putamen of human brain

Radiochemical neutron activation analysis has been used to determine the concentration of 36 elements in neuromelanin, 22 elements in substantia nigra, and 32 elements in putamen of healthy subjects without signs of neurological disorders. Substantia nigra and putamen tissues were carefully dissected from the brain using special surgical instruments and tools as well as an adequate sampling procedure to avoid the risk of metal contamination during sampling. Neuromelanin was isolated from putamen by a multiple-step procedure (extraction with phosphate buffer, lipid and protein elimination by methanol extraction, and sodium dodecyl sulfate-proteinase). The isolated pigment as well as substantia nigra and putamen underwent neutron activation analysis involving irradiation in a high-neutron-flux reactor, radiochemical separations, and counting of the induced radionuclides by computer-based gamma-ray spectrometry. Iron was the element present in the highest concentration in all analyzed samples. The amount of iron was similar in substantia nigra and putamen (3,000 and 3,830 ng/mg wet weight, respectively) and 10 times higher in neuromelanin (30,800 ng/mg dry weight). Zinc was also present at high levels in three samples, ranging from 16.8 (substantia nigra) to 1,500 ng/mg (neuromelanin). Elements such as Zn, Cr, Se, Sr, Co, Sb, Ni, Hg, Ce, Au, Ag, Ta, and Sc were present in neuromelanin at much higher concentrations than in substantia nigra and putamen. These findings indicate that substantia nigra and putamen contain metals at higher concentrations than observed in blood and that neuromelanin has a particular affinity for metals.

Cognitive and magnetic resonance imaging aspects of corticobasal degeneration and progressive supranuclear palsy

OBJECTIVE

To identify cognitive and MRI features important for the clinical diagnosis of corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP); these diseases share several clinical features and are often difficult to distinguish on clinical grounds.

METHODS

Cognitive functions and MRI characteristics were examined in 16 patients with CBD and 28 patients with PSP, all diagnosed according to current clinical criteria (none was examined by autopsy).

RESULTS

MRI findings differed significantly between the two groups: 87.5% of patients with CBD but none with PSP had asymmetric frontoparietal atrophy, whereas 89.3% of patients with PSP but only 6.3% of those with CBD had midbrain atrophy. Cognitive examination showed that ideomotor apraxia (De Renzi's test) was significantly more frequent in CBD, and executive functions (Nelson's test) were significantly more impaired in patients with PSP.

CONCLUSIONS

MRI findings of asymmetric frontoparietal atrophy in CBD and midbrain atrophy in PSP are the most consistent and useful aids to careful clinical evaluation for differentiating between the two diseases.

Comparison of HE4, CA125 and ROMA algorithm in women with a pelvic mass: correlation with pathological outcome

OBJECTIVE

The quality of first surgery is one of the most important prognostic factors in ovarian cancer patients. Pre-surgical distinction of benign and malignant pelvic mass plays a critical role in ovarian cancer management and survival. The aim of this study was to evaluate the clinical performance of ROMA algorithm and of CA125 and HE4 in the triage of patients with a pelvic mass undergoing surgery, in order to discriminate benign from malignant disease.

METHODS

Three hundred and forty-nine pre- and post-menopausal women, aged 18 years or older undergoing surgery because of a pelvic mass were enrolled: serum concentrations of CA125 and HE4 were determined and ROMA was calculated for each sample.

RESULTS

Median serum CA125 and HE4 levels were higher in patients with EOC compared to subjects with benign disease (p<0.0001). The resultant accuracy (using Receiver Operating Characteristics, ROC Area) values for HE4, CA125 and ROMA showed a good performance ranging from 89.8% for CA125 in pre-menopausal patients to 93.3% for ROMA in post-menopausal patients: AUC for ROMA resulted significantly higher in comparison to CA125 alone (93.3% vs 90.3%, p=0.0018) in post menopausal patients. A sub-analysis considering the 40 patients with endometrioid disease showed the highest accuracy of HE4 in these patients.

CONCLUSIONS

Data presented confirm the accuracy of HE4 and of the ROMA algorithm in the distinction of ovarian carcinoma from benign disease, with a trend towards better performance for ROMA than for CA125 alone, statistically significant in postmenopausal patients.

Health status of people with multiple sclerosis: a community mail survey

We assessed the self-perceived health status of people with multiple sclerosis (MS) living in the Province of Milan, and the consequences of the disease on family, social and occupational status, using a cross-sectional mail survey. We identified 1350 adults with MS living in the Province of Milan. To a random sample of 400 of these, we sent out the multiple sclerosis quality-of-life-54 questionnaire (MSQOL-54), the proxy version of the short form-36 (SF-36), and a sociodemographic and clinical questionnaire. We received 261 replies (65%). Demographic and clinical data of responders and non-responders were similar except for frequency of hospitalisation over the last year, which was higher in responders. Compared to Italian norms, the MS patients had lower scores in all SF-36 domains; the differences were greatest for physical function, physical role limitations, vitality, and general health perceptions. Unemployment was 103 (41%) overall, 45% in women, and 54% in the less educated. A proxy informant was available for 245 (96%) responders. Concordance between patient and proxy reports on the SF-36 was moderate to excellent. MS had a pervasive impact on patients' lives, with substantial negative consequences for family and working life, that generally make themselves felt in the most active and productive period of people's live.

Reliability of clinical outcome measures in Charcot-Marie-Tooth disease

We assessed inter- and intra-rater reliability of outcome measures in Charcot-Marie-Tooth disease (CMT) patients. In 40 CMT patients, we assessed reliability of Overall Neuropathy Limitations Scale (ONLS), 10-m timed walk (T10MW), 9-hole-peg test (9-HPT), maximal voluntary isometric contraction (MVIC) of arm (elbow flexion, hand-grip, and three-point pinch) and leg (knee extension, foot dorsiflexion/plantar flexion). Reliability was substantial for ONLS, excellent for T10MW and 9-HPT. For MVIC, inter and intra-rater reliability was excellent for hand contractions; for leg contractions, intra-rater agreement was moderate to substantial, whereas inter-rater agreement was poor. An ad hoc device was produced to immobilize the foot and MVIC reliability was re-assessed in 26 CMT patients, resulting in excellent inter-rater and intra-rater reliability for foot dorsiflexion, and clear inter-rater improvement for foot plantar flexion. All outcome measures appear adequate for CMT assessment. Use of an immobilization device improves foot MVIC reliability, preventing biased findings in patients with greater strength.

Cognitive dysfunction and impaired organization of complex motility in degenerative parkinsonian syndromes

BACKGROUND

A frontostriatal pattern of cognitive decline, consisting of a frontal lobe-like syndrome without genuine cortical defects such as amnesia, apraxia, aphasia, or agnosia, is well established in basal ganglial diseases. Recent pathological investigations, however, have again noted cortical damage in progressive supranuclear palsy (PSP), suggesting that cortical defects could be present.

OBJECTIVES

To delineate the pattern of cognitive impairment and to detect higher-order motor impairments (including ideomotor apraxia) in parkinsonian syndromes.

PATIENTS AND METHODS

We assessed ideomotor apraxia, and simple and sequential tapping in patients with Parkinson disease, multiple system atrophy, and PSP with similar disease severity, age range, and education. We also administered a comprehensive battery of neuropsychological tests to examine general intelligence, memory, executive functions, attention, and visuospatial orientation. The results were compared between groups and with a matched normal control group.

RESULTS

Sequential tapping and the imitation of sequences of gestures were impaired in all patient groups, with patients with PSP performing worse than the other groups. Based on ideomotor apraxia scores and a qualitative analysis of errors, 3 patients with PSP and 2 with multiple system atrophy were considered apraxic. General intelligence and executive functions were compromised in all patient groups. The impairment of patients with PSP was more pervasive than that of the other groups, and included compromise of visuospatial functions, attention, and memory. Discriminant analysis of all cognitive and motor tests showed that the tapping and ideomotor apraxia tests best identified the patients vs control subjects.

CONCLUSIONS

The presence of cortical as well as subcortical damage in patients with PSP and those with multiple system atrophy is indicated by the presence of pervasive cognitive and motor disturbances in the former, substantial motor disorganization in the latter, and the finding of ideomotor apraxia in some patients with these diseases. Furthermore, the discovery that tests of motor and gesture best identified all patients vs control subjects is consistent with the existence of a common motor disorganization in these parkinsonian syndromes, in agreement with the known damage to the corticostriatal pathways in these conditions.

The Multiple Sclerosis Knowledge Questionnaire: a self-administered instrument for recently diagnosed patients

There are few studies on patient knowledge in multiple sclerosis (MS), and only two published questionnaires. The objective of this article was to develop and validate the MS Knowledge Questionnaire (MSKQ), a self-assessed instrument for newly diagnosed MS patients. Thirty multiple-choice statements, conceived to test MS knowledge, were produced by a multidisciplinary panel and pre-tested on three MS patients, resulting in an intermediate 26-item version. This was tested on 54 MS patients for internal consistency, content and construct validity (validation sample I). The final (25-item) MSKQ was a primary outcome measure in the SIMS-Trial on an information aid to newly diagnosed MS patients. Postal responses of SIMS-Trial participants to the MSKQ a month after intervention (validation sample II) were analysed. Median MSKQ scores in validation samples I and II were, respectively, 18 (range 9-23) and 17 (range 3-24). Acceptability, internal consistency (Kuder-Richardson-20 formula 0.76) and content validity were good. Educational attainment and receiving the information aid were the main independent predictors of MS knowledge. Other predictors were female sex (positive association) and disease duration (negative association). In conclusion, the MSKQ has good clinimetric properties and is sensitive to an educational intervention. We propose the MSKQ as a brief instrument for clinical practice and research.

Health-related quality of life and depressive symptoms in significant others of people with multiple sclerosis: a community study

BACKGROUND AND PURPOSE

 Uncertain prognosis and modest treatment efficacy make multiple sclerosis (MS) a particularly difficult disease to adjust to for both patients and their significant others (SOs). Few studies have assessed health-related quality of life (HRQOL) and depressive symptoms in SOs of people with MS in the community. We assessed, and identified predictors of, HRQOL and depression in SOs of adults with MS.

METHODS

  POSMOS (postal survey of self-assessed health in MS adults and SOs) is a longitudinal survey on a random sample of 251 people with MS in the Milan area. In 2010, SOs and contemporaneous controls completed the SF-36 and Chicago Multiscale Depression Inventory (CMDI).

RESULTS

  Overall, 142 SOs (mean age 53.1 years; 50% women, 65% partners) and 120 controls (similar to SOs for sex and education, but older) participated. By multivariable modeling of the SO plus control population, SF-36 vitality was lower in SOs (proportional odds ratio 0.45; 95% confidence interval 0.28-0.70), women (0.41; 0.27-0.64), and older subjects (0.98; 0.97-0.99). SF-36 mental health was also lower in SOs (0.62; 0.40-0.96) and women (0.43; 0.28-0.67). Regarding MS characteristics associated with HRQOL and depression in SOs, severe disability [Expanded Disability Status Scale (EDSS > 6.5)] had no effect, whilst depressive symptoms (pathologic CMDI) negatively influenced most SF-36 and all CMDI scores in SOs.

CONCLUSIONS

  SOs had significantly lower vitality and psychological well-being than controls, identifying a burden in being the companion of a person with MS. This burden was unrelated to physical compromise but associated with depressive symptoms in MS.

Role of multidetector CT and FDG-PET/CT in the diagnosis of local and distant recurrence of resected rectal cancer

PURPOSE

The aim of this study was to compare the diagnostic value of multidetector computed tomography (MDCT) and F18-fluorodeoxyglucose positron emission tomography-computed tomography (FDG-PET/CT) for the detection of local and distant recurrence in patients operated on for rectal cancer.

MATERIALS AND METHODS

Sixty-seven patients who underwent radical surgery for rectal cancer and were followed up with FDG-PET/CT and MDCT were included in this retrospective study. The FDG-PET/CT and MDCT findings were independently compared with histological sampling or 2 years' follow-up.

RESULTS

Local recurrence occurred in 15/67 patients. MDCT diagnosed local recurrence in 15/15 cases and FDG-PET/CT in 14/15. Sensitivity and specificity were 100% and 98% for MDCT and 93% and 98% for FDG-PET/CT, respectively. Hepatic lesions were found in 17/67 patients. All hepatic metastases were detected by both techniques. Pulmonary metastases occurred in 8/67 patients: they were correctly identified in all cases by MDCT and in 6/8 by FDG-PET/CT.

CONCLUSIONS

MDCT and FDG-PET/CT showed high sensitivity and specificity for the detection of local recurrence of rectal cancer. Both techniques were equally accurate for the detection of hepatic metastases. MDCT showed slightly higher sensitivity and positive predictive value in detecting pulmonary metastases compared with FDG-PET/CT.

Risk of second primary malignancies among 1537 melanoma patients and risk of second primary melanoma among 52 354 cancer patients in Northern Italy

BACKGROUND

The number of melanoma survivors has been increasing for decades due to early diagnosis and improved survival. These patients have an increased risk of developing a second primary cancer (SPC); also, melanoma is frequently diagnosed among patients firstly diagnosed with an extracutaneous malignancy.

OBJECTIVE

We evaluated the risk of developing a SPC among 1537 melanoma patients, and the risk of second primary melanoma (SPM) in 52 354 extracutaneous cancer patients, who were treated at the European Institute of Oncology in Milan, Italy, during 2000-2010.

MATERIAL AND METHODS

We calculated standardized incidence ratios (SIR) by applying gender-, age-, year- and region-specific reference rates to the follow-up time accrued between the diagnosis of the first and the second primary malignancies.

RESULTS

Seventy-six SPC were diagnosed during a median follow-up of 4 years, of which 49 (64%) during the first 2 years upon melanoma diagnosis. The SIR was increased for cancer of breast (4.10, 95% CI 2.79-6.03), thyroid (4.67, 95% CI 1.94-11.22), brain (6.13, 95% CI 2.30-16.33) and for non-Hodgkin lymphoma (3.12, 95% CI 1.30-7.50). During a median follow-up of 4 years, 127 SPM were diagnosed: thick lesions were less frequent than for melanoma diagnosed as first cancer. The SIR was increased for cancer of breast (5.13, 95%CI 3.91-6.73), thyroid (16.2, 95%CI: 5.22-50.2), head and neck (5.62, 95%CI 1.41-22.50), soft tissue (8.68, 95%CI 2.17-34.70), cervix (12.5, 95% CI 3.14-50.20), kidney (3.19, 95%CI 1.52-6.68), prostate (4.36, 95%CI 2.63-7.24) and acute myeloid leukaemia (6.44, 95%CI 2.42-17.20).

CONCLUSIONS

The most likely causes of these associations are the clustering of lifestyle risk factors in the same subgroups of population, mainly on a sociocultural basis and surveillance bias. This raises important questions about how to best follow cancer survivors by avoiding an inefficient use of resources and an excessive medicalization of these patients' lives.

Expression of gemcitabine- and cisplatin-related genes in non-small-cell lung cancer

The aim of this study was to investigate the influence of histology and site of analysis (primary tumor versus lymph node) on the expression of genes involved in gemcitabine and cisplatin activity in non-small-cell lung cancer (NSCLC). Excision repair cross-complementing-1 (ERCC1), human equilibrative nucleoside transporter-1 (hENT1), deoxycytidine kinase (dCK), 5'-nucleotidase (5'-NT), cytidine deaminase (CDA) and ribonucleotide-reductase regulatory subunits (RRM1 and RRM2) were analyzed by quantitative-reverse transcription-PCR in 88 microdissected samples from 69 chemonaive patients. The results showed different patterns of expression for all studied genes, suggesting a possible stratification of the patients. No difference was observed between primary tumor and lymph node metastasis, as well as in adenocarcinoma and squamous-cell carcinoma specimens, while we found a correlation between the CDA-A79C polymorphism and gene expression levels. These data suggest a similar genetic susceptibility to gemcitabine-cisplatin regimens for squamous cell and adenocarcinoma and support the use of both lymph node and primary tumor for the expression profiling of NSCLC.

Increased plasma bilirubin in Parkinson patients on L-dopa: evidence against the free radical hypothesis?

Oxidative damage by free radicals may contribute to the etiology of Parkinson's disease (PD), and increased oxidative stress in the nigral cells of PD patients may occur following L-dopa treatment, prompting suggestions that L-dopa therapy should be delayed as long as possible. Bilirubin is a potent antioxidant in vitro, even when bound to albumin, suggesting a physiological role as an antioxidant. Calculations indicate that bilirubin can pass the blood-brain barrier in sufficient quantity to exert a significant antioxidant effect in the brain. We have found a highly significant (about 20%) increase in plasma bilirubin in 162 PD patients on chronic L-dopa treatment compared to 93 untreated parkinsonians and 224 non-parkinsonian controls. We propose that L-dopa-induced increase in nigral oxidative stress in PD may be effectively counteracted by increased bilirubin levels. The mechanism by which plasma bilirubin is increased in patients receiving L-dopa is at present unknown.

Is overwork weakness relevant in Charcot-Marie-Tooth disease?

BACKGROUND

In overwork weakness (OW), muscles are increasingly weakened by exercise, work or daily activities. Although it is a well-established phenomenon in several neuromuscular disorders, it is debated whether it occurs in Charcot-Marie-Tooth disease (CMT). Dominant limb muscles undergo a heavier overload than non-dominant and therefore if OW occurs we would expect them to become weaker. Four previous studies, comparing dominant and non-dominant hand strength in CMT series employing manual testing or myometry, gave contradictory results. Moreover, none of them examined the behaviour of lower limb muscles.

METHODS

We tested the OW hypothesis in 271 CMT1A adult patients by comparing bilateral intrinsic hand and leg muscle strength with manual testing as well as manual dexterity.

RESULTS

We found no significant difference between sides for the strength of first dorsal interosseous, abductor pollicis brevis, anterior tibialis and triceps surae. Dominant side muscles did not become weaker than non-dominant with increasing age and disease severity (assessed with the CMT Neuropathy Score); in fact, the dominant triceps surae was slightly stronger than the non-dominant with increasing age and disease severity.

DISCUSSION

Our data does not support the OW hypothesis and the consequent harmful effect of exercise in patients with CMT1A. Physical activity should be encouraged, and rehabilitation remains the most effective treatment for CMT patients.

Cost-effectiveness analysis of exemestane compared with megestrol in patients with advanced breast carcinoma

BACKGROUND

The objective of this study was to determine the potential economic implications resulting from using exemestane (EXE), a new steroidal, irreversible aromatase inactivator, compared with megestrol acetate (MA) in patients with advanced breast carcinoma.

METHODS

The model used the clinical results from the manufacturer-sponsored, international, randomized, controlled, double-blind trial of patients with postmenopausal, tamoxifen-refractory advanced breast carcinoma. Seven hundred sixty-nine women were randomized to EXE 25 mg per day or MA 40 mg four times daily EXE was well tolerated, significantly delayed tumor progression (relative risk [RR], 0.82; 95% confidence interval [95% CI], 0.70-0.97), and prolonged survival (RR, 0.77; 95% CI, 0.59-0.99). Lifetime effectiveness projections were made using the trial efficacy results to the U.S. market using a 1000-day ( approximately 3-year) time frame. Because the median survival of patients who received EXE was not reached, it was projected from the Cox model. There were no differences in the rate of hospitalization. The average wholesale prices for EXE and MA were used.

RESULTS

Patients who received EXE were projected to have a mean survival benefit of 53.5 days (estimated 95% CI, 2-100 days) and to incur at an additional cost of $1559 per patient (estimated 95% CI, 880-2075 dollars). The incremental cost effectiveness (CE) ratio using EXE was 10,600 dollars per life year gained (estimated 95% CI, 6200-209,000 dollars). If MA had no costs, then the CE ratio increased to 12,200 dollars per life year. Using a 5-year projection, the CE ratio for EXE was 5900 dollars per life year. The projected survival at 1000 days was 53.9% in the EXE cohort compared with 44.8% in the MA cohort.

CONCLUSIONS

EXE, compared with MA, is projected to increase survival at a modest added cost. If treatment with EXE delays or defers initiating more costly therapies, then it may even be cost saving.

Long-term effects of inhaled budesonide on screening-detected lung nodules

BACKGROUND

A previously carried out randomized phase IIb, placebo-controlled trial of 1 year of inhaled budesonide, which was nested in a lung cancer screening study, showed that non-solid and partially solid lung nodules detected by low-dose computed tomography (LDCT), and not immediately suspicious for lung cancer, tended to regress. Because some of these nodules may be slow-growing adenocarcinoma precursors, we evaluated long-term outcomes (after stopping the 1-year intervention) by annual LDCT.

PATIENTS AND METHODS

We analyzed the evolution of target and non-target trial nodules detected by LDCT in the budesonide and placebo arms up to 5 years after randomization. The numbers and characteristics of lung cancers diagnosed during follow-up were also analyzed.

RESULTS

The mean maximum diameter of non-solid nodules reduced significantly (from 5.03 mm at baseline to 2.61 mm after 5 years) in the budesonide arm; there was no significant size change in the placebo arm. The mean diameter of partially solid lesions also decreased significantly, but only by 0.69 mm. The size of solid nodules did not change. Neither the number of new lesions nor the number of lung cancers differed in the two arms.

CONCLUSIONS

Inhaled budesonide given for 1 year significantly decreased the size of non-solid nodules detected by screening LDCT after 5 years. This is of potential importance since some of these nodules may progress slowly to adenocarcinoma. However, further studies are required to assess clinical implications.

Comparison of oral polyethylene glycol plus a large volume glycerine enema with a large volume glycerine enema alone in patients undergoing colorectal surgery for malignancy: a randomized clinical trial

AIM

Recent meta-analyses and randomized clinical trials have concluded that mechanical bowel preparation (MBP) before elective colorectal surgery is not associated with a reduction of surgical site infection (SSI). The aim of this randomized clinical trial was to evaluate the impact of preoperative MBP for colon and rectal cancer surgery in comparison with a single glycerine enema.

METHOD

Patients scheduled for radical colorectal resection for malignancy with primary anastomosis were randomized to preoperative MBP (4 l of polyethylene glycol) (group 1, 114 patients) plus a glycerine 5% enema (2 l) or a single glycerine 5% enema (2 l) (group 2, 115 patients). The postoperative incidence of SSI was recorded prospectively. Patients undergoing minimally invasive surgery (laparoscopy or robotic) accounted for 55 and 51 in groups 1 and 2 respectively.

RESULTS

In all, 229 patients were included in the study, 114 in group 1 and 115 in group 2. At least one SSI was reported in 16 (14.0%) group 1 and in 20 (17.8%) group 2 patients (P=0.475). Perioperative mortality was nil. The incidence of SSI was comparable also in the 73 patients who had a low anterior resection (seven of 33 vs eight of 40, P=1.000), and for the 106 patients who underwent a minimally invasive procedure (nine of 55 vs four of 51, P=0.241).

CONCLUSION

A single large-volume glycerine enema is effective bowel preparation before colorectal resection whether performed by an open or minimally invasive technique.

Aspirin does not affect exercise performance

A single-blind, cross-over study was carried out to evaluate the effects of acetylsalicylic acid (ASA) on cardiorespiratory performance during exercise. Eighteen young men, 9 athletes and 9 untrained but active subjects, performed a progressive maximal exercise test on a cycle ergometer (30 watt, 3 min steps, starting at 60 watt) on three different occasions, after a single administration of plain aspirin (1000mg of ASA), chewable buffered aspirin (1000mg of ASA and 600 mg of calcium carbonate) and placebo. Continuous measurement of breath-by-breath ventilation, oxygen consumption, carbon dioxide output, respiratory frequency and heart rate was carried-out at rest and during the exercise test. Blood lactate concentration was measured just before the start of exercise and at the third minute of each step in order to detect the anaerobic threshold. The pharmacokinetics of aspirin during exercise was also investigated in ten of the eighteen participants. The analysis of all investigated variables did not show any statistically significant difference between treatments, suggesting that a single dose of 1000mg of aspirin does not affect physical performance during submaximal and maximal exercise.

Implementation of the ‘Sapere Migliora’ information aid for newly diagnosed people with multiple sclerosis in routine clinical practice: a late-phase controlled trial

Background:

The SIMS-Trial showed that the ‘Sapere Migliora’ information aid (IA) for newly diagnosed people with multiple sclerosis (PwMS) effectively improved patient knowledge and satisfaction with care.

Objectives:

The objectives of this paper are to assess the effectiveness of the IA in clinical practice and to compare the whole IA with the take-home booklet/website component alone.

Methods:

After updating the IA and replacing the CD with a website, a prospective, open-label non-randomised controlled trial compared the whole IA (group A, five SIMS-Trial centres) to take-home (group B, 16 centres). One month after the intervention, participants completed the MS Knowledge Questionnaire (MSKQ), care satisfaction questionnaire (COSM-R) (primary study outcomes), Hospital and Anxiety Depression Scale, and ad hoc questionnaire appraising the IA.

Results:

We enrolled 159 newly diagnosed PwMS (May 2012–March 2013). Drop-outs were four of 77 (5%, group A) and 11/82 (13%, group B). Primary endpoint (highest tertile both for MSKQ and COSM-R section 2 scores) was achieved by 38/77 (49%) group A and 33/82 (40%) group B ( p = 0.25). Attainment of secondary outcomes was also similar between groups.

Conclusions:

This study shows that the entire IA is not superior to the booklet/website alone, and that both are comparable in efficacy to the intervention arm of the SIMS-Trial.

Trial registration number:

ISRCTN78940214.
