Time trends (2006-2015) of quality indicators in EUSOMA-certified breast centres.

AIM OF THE STUDY: The European Society of Breast Cancer Specialists (EUSOMA) has fostered a voluntary certification process for breast centres to establish minimum standards and ensure specialist multidisciplinary care. Prospectively collected anonymous information on primary breast cancer cases diagnosed and treated in the units is transferred annually to a central EUSOMA data warehouse for continuous monitoring of quality indicators (QIs) to improve quality of care. Units have to comply with the EUSOMA Breast Centre guidelines and are audited by peers. The database was started in 2006 and includes over 110,000 cancers from breast centres located in Germany, Switzerland, Belgium, Austria, The Netherlands, Spain, Portugal and Italy. The aim of the present study is assessing time trends of QIs in EUSOMA-certified breast centres over the decade 2006-2015. MATERIALS AND METHODS: Previously defined QIs were calculated for 22 EUSOMA-certified breast centres (46122 patients) during 2006-2015. RESULTS: On the average of all units, the minimum standard of care was achieved in 8 of 13 main EUSOMA QIs in 2006 and in all in 2015. All QIs, except removal of at least 10 lymph nodes at axillary clearance and oestrogen receptor-negative tumours (T > 1 cm or N+) receiving adjuvant chemotherapy, improved significantly in this period. The desirable target was reached for two QIs in 2006 and for 7 of 13 QIs in 2015. CONCLUSION: The EUSOMA model of audit and monitoring QIs functions well in different European health systems and results in better performance of QIs over the last decade. QIs should be evaluated and adapted on a regular basis, as guidelines change over time.

FGFR4 Arg388 genotype is associated with pathological complete response to neoadjuvant chemotherapy for primary breast cancer.

BACKGROUND: A single-nucleotide polymorphism (SNP) in the FGFR4 gene is associated with poor prognosis in solid tumors. A recent study presented the first evidence that FGFR4 Arg388 could predict resistance to adjuvant chemotherapy in breast cancer. The present study evaluates the potential of this SNP to predict response to neoadjuvant chemotherapy (NCT) for primary breast cancer (PBC). METHODS: As part of a randomized phase II trial, 257 patients received either doxorubicin-cyclophosphamide (AC) or doxorubicin-pemetrexed (AP) followed by docetaxel (Doc; Taxotere) as NCT for T2-4/N0-2/M0 PBC. FGFR4 genotype analyzed on germline DNA was correlated with clinicopathologic variables, clinical response, and pathological complete response (pCR) using univariate and multivariate analyses. RESULTS: Only axillary lymph node status was associated with FGFR4 Arg388 [odds ratio (OR) 1.82, P = 0.03]. Joint analysis of both treatment arms revealed a correlation of FGFR4 Arg388 with clinical response (OR 2.14, P = 0.03) but not with pCR. In the AC-Doc arm, however, FGFR4 Arg388 was a strong predictor of pCR in the multivariate analysis (OR 3.79, P = 0.03). A significant interaction between FGFR4 genotype and treatment (P = 0.01) was found, indicating a therapy-specific effect. CONCLUSION: We provide the evidence that FGFR4 388Arg is an independent predictor of pCR following AC-Doc as NCT in PBC.

Quality and effect of single dose versus split dose of polyethylene glycol bowel preparation for early-morning colonoscopy.

BACKGROUND AND STUDY AIMS: The conventional procedure of ingestion of an entire dose of polyethylene glycol solution on the day before early-morning colonoscopy may result in poor bowel preparation. The aim of this study was to evaluate the efficacy and effect of a split-dose ingestion of polyethylene glycol for early-morning colonoscopy. METHODS: A total of 303 age- and sex-matched consecutive individuals presenting for medical check-ups were randomly assigned to receive either 4 L of polyethylene glycol solution with a soft diet on the day before colonoscopy (n = 152; group A), or 3 L of polyethylene glycol solution with a soft diet on the preceding day and then 1 L of the solution on the day of colonoscopy (n = 151; group B). The quality of bowel preparation was evaluated using the Ottawa scale, and the time to cecal intubation and the technical difficulty during the procedure were also recorded. RESULTS: There was no difference in compliance between group A (single-dose) and group B (split-dose). The quality of bowel preparation was better in group B compared with group A. When the participants were categorized according to compliance (good compliance, 116 in group A, 119 in group B; poor compliance, 36 in group A, 32 in group B), the quality of the bowel preparation had a higher score in the good compliance compared with the poor compliance group, and in group B this difference was usually significant. CONCLUSIONS: Split-dose bowel preparation with polyethylene glycol solution provided a better quality preparation than the conventional method for patients undergoing early-morning colonoscopy.

[Influence of antenatal acupuncture on cardiotocographic parameters and maternal circulation - a prospective study]. / Einfluss von antenataler Akupunktur auf kardiotokographische Parameter und maternalen Kreislauf - Eine prospektive Studie.

BACKGROUND: Acupuncture as a non-evidence-based therapy modality is widely used in obstetrics prior to and during delivery. Thus far, only few studies investigated the impact of acupuncture on obstetric surveillance parameters like cardiotocography. The aim of this study was to control the effect of clearly-defined acupuncture on CTG parameters. PATIENTS AND METHODS: 61 low-risk singleton pregnancies between 30 + 0 and 39 + 6 weeks of gestation were prospectively treated with acupuncture at GV 20 and ST 36 bilaterally for the purpose of maternal relaxation by the same investigator under CTG control. Before (Phase 1), during (Phase 2) and after (Phase 3) treatment the cardiotocogram was recorded. Controlled parameters of outcome were the Fisher score, uterine activity (Phase 1, 2, 3) and maternal blood pressure and pulse before (Phase 1) and after (Phase 2) administration of acupuncture. In a matched control group, 60 pregnant women were monitored by an identical scheme without application of acupuncture and the same outcome parameters were recorded. RESULTS: : The CTG analysis revealed a statistically significant increase of the Fisher score as well as uterine activity which tended to trace back to pretherapeutic initial values. The systolic maternal blood pressure was found to show a statistically significant decrease while diastolic blood pressure and pulse frequency remained unchanged. In the control group, the comparison of phase 1 vs. phase 2 showed a statistically significant increase of the Fischer score and uterine activity. During phase 3 the Fischer score further increased in contrast to a statistically significant slight reduction of uterine activity. Maternal systolic blood pressure measured at the end of phase 2 was found to be statistically reduced while diastolic blood pressure and pulse remained unchanged. The extent of the systolic blood pressure reduction was markedly higher in the acupuncture group as compared to the control group. CONCLUSIONS: Antenatal acupuncture as a reflex therapy for the purpose of maternal relaxation seems to exert an influence on short-term alterations of the fetal activity (transient increase in terms of Fischer score) with reversibly increased uterine activity as detected by cardiotocography. Also, a slight reduction of the maternal blood pressure seems to be effected. The phenomena recorded in the control group (relaxation without supportive acupuncture treatment) revealed to be partially concordant (reversibly increased uterine activity, mild maternal reduction of systolic blood pressure) and partially discordant (persisting increase of Fischer score) as compared with the acupuncture group. Acupuncture seems not only to have a psychological, but also a short-term somatic effect with direct influence on maternal and fetal circulation parameters. Other established surveillance parameters and different points of acupuncture should be studied to further elucidate the underlying interaction as well as the duration of this effect.

Dietary iodine intake and urinary iodine excretion in normal Korean adults.

Korea is a region abundant in foods containing iodine such as seaweed and fish. An adequate amount of iodine consumption is extremely important as both a deficiency and excess of iodine can result in health problems. This study was undertaken to assess the iodine nutritional status of normal Korean adults who consume seaweed and fish, and to determine the relationship between the dietary iodine intake and the urinary excretion of iodine. The dietary assessment of iodine using a food frequency questionnaire and a urinary iodine excretion examination were carried out in 278 healthy adults. The iodide selective electrode (ISE) method was used to determine urinary iodine excretion. The average usual iodine intake of Korean adults was 479 micrograms per day (ranging from 61 micrograms to 4086 micrograms). There was no significant difference in sex or age. The major food sources of dietary iodine included seaweed (66%), milk and dairy products (11%), and fish (9%). The contribution of seaweed to the total iodine intake tended to increase with age while the contribution of milk decreased. The average urinary excretion of iodine was 674 micrograms/g creatinine and there was no significant difference in sex or age. The dietary iodine intake was positively correlated with the urinary excretion of iodine (gamma = 0.60, p < 0.01). The study data indicated that the iodine intake and excretion of Koreans depends mostly on the amount of seaweed consumption like sea tangle and sea mustard. As well, the current iodine intake and urinary iodine excretion by Koreans seems to be higher than in other countries.

Treatment of the twin-twin transfusion syndrome: initial experience using laser-induced interstitial thermotherapy.

This paper describes our initial experience with laser-induced interstitial thermotherapy (LITT) for the treatment of the twin-twin transfusion syndrome (TTTS). This procedure was utilized in four pregnancies-three monochorionic twin pregnancies and one triplet pregnancy (20-26 weeks of gestation)-with severe TTTS with fetal dropsy, polyhydramnion of the acceptor, and anhydramnion of the donor. In vitro examinations of placental tissue had shown that laser coagulation can be monitored by sonography, hence we used this method for the first time in these four pregnancies. Blood vessels connecting the two umbilical cords were determined prior to the treatment using a new ultrasound color technique which is highly sensitive and capable of representing slow blood flow velocities. A 1.2 mm thick puncture needle was then directed to the shunt under on-line ultrasound control. All patients had an anterior wall placenta. The laser fiber was inserted via this thin needle. A coagulation time of 2-3 min was necessary at 3 W. In the one twin pregnancy the intrauterine fetal death of the smaller child occurred 10 weeks after LITT, the other child survived and is healthy. A cesarian section was necessary in another twin pregnancy 1 week after LITT due to the intrauterine death of the smaller child. In the third twin pregnancy, the donor, who had already had distinct bradycardia prior to the treatment, died immediately after LITT. The intrauterine fetal death of the donor in the triplet pregnancy occurred 3 days after LITT once the volume of amniotic fluid had basically returned to normal. The tragic intrauterine death of the uninvolved child occurred 13 weeks later as a result of umbilical cord strangulation, the surviving child is healthy. All four pregnancies were severe and advanced cases of TTTS with a very poor prognosis, leaving us with no other alternative to the described method of treatment. The instruments we used are a lot thinner than those utilized for fetoscopic laser treatment to date. Furthermore, it is not necessary to penetrate the amniotic sac in patients with an anterior wall placenta; intraplacental vessels can be coagulated, and the laser energy required for LITT is also much lower. In our opinion these advantages justify the utilization of LITT under more promising conditions than those described above.

Five cephalosporins: pharmacokinetics and their relation to antibacterial potency.

In a group of adult volunteers, pharmacokinetic profiles of five cephalosporins were correlated with their minimal inhibitory concentrations (MICs90) against Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Enterobacter aerogenes. Subjects received the following intravenous regimens in a randomized, crossover fashion: (1) 0.5 gm, 1 gm, or 2 gm of cefazolin; (2) 2 gm of cephalothin; (3) 1 gm of cephapirin; (4) 1 gm of cefoxitin; or (5) 0.5 gm of cefamandole. The 500-mg dose of cefazolin produced serum concentrations that exceeded those of any of the other cephalosporins at 0.5, 1, 2, 4, and 6 hours after administration. The area under the curve for this dose of cefazolin was at least twice that of any of the other antibiotics. Two hours after a 500-mg dose of cefazolin, serum levels exceeded the MIC90 for all seven groups of pathogens; at six hours, the 500-mg dose of cefazolin continued to achieve serum levels above the MIC90 against the majority of bacterial groups. In contrast, at two hours after administration none of the other cephalosporins maintained serum levels above the MIC90 for all pathogens; at six hours, the levels of cephapirin were adequate to inhibit the two streptococci, but serum levels of all other cephalosporins were inadequate to inhibit any of the pathogens. These data indicate that a 500-mg dose of cefazolin maintains serum levels above the MICs90 longer than any of the other cephalosporins tested and support the use of a 500-mg dose of cefazolin every eight hours for surgical prophylaxis and treatment of most community-acquired infections. Such a comparatively low dosage offers substantial savings to both patient and hospital.
