ABSTRACT

BACKGROUND: Type I and type II diabetes mellitus (DM) patients have a higher prevalence of cardiovascular diseases, as well as a higher mortality risk of cardiovascular diseases and interventions. This study provides an update on the impact of DM on clinical outcomes, including mortality, complications and reinterventions, using data on percutaneous and surgical cardiac interventions in the Netherlands. METHODS: This is a retrospective, nearby nationwide study using real-world observational data registered by the Netherlands Heart Registration (NHR) between 2015 and 2020. Patients treated for combined or isolated coronary artery disease (CAD) and aortic valve disease (AVD) were studied. Bivariate analyses and multivariate logistic regression models were used to evaluate the association between DM and clinical outcomes both unadjusted and adjusted for baseline characteristics. RESULTS: 241,360 patients underwent the following interventions; percutaneous coronary intervention(N = 177,556), coronary artery bypass grafting(N = 39,069), transcatheter aortic valve implantation(N = 11,819), aortic valve replacement(N = 8,028) and combined CABG and AVR(N = 4,888). The incidence of DM type I and II was 21.1%, 26.7%, 17.8%, 27.6% and 27% respectively. For all procedures, there are statistically significant differences between patients living with and without diabetes, adjusted for baseline characteristics, at the expense of patients with diabetes for 30-days mortality after PCI (OR = 1.68; p <.001); 120-days mortality after CABG (OR = 1.35; p <.001), AVR (OR = 1.5; p <.03) and CABG + AVR (OR = 1.42; p =.02); and 1-year mortality after CABG (OR = 1.43; p <.001), TAVI (OR = 1.21; p =.01) and PCI (OR = 1.68; p <.001). CONCLUSION: Patients with DM remain to have unfavourable outcomes compared to nondiabetic patients which calls for a critical reappraisal of existing care pathways aimed at diabetic patients within the cardiovascular field.

ABSTRACT

Background: Septate uterus is the most common uterine malformation found in women presenting poor reproductive history. Hysteroscopic septoplasty (HS) restores the uterine anatomy in a safe procedure. Objectives: The goal of our study is to determine the reproductive outcomes after HS of symptomatic septate uterus. Materials and Methods: In a retrospective observational single centre study the reproductive outcomes and complications after HS were evaluated in 31 women with symptomatic septate uterus. The patients were separated into two groups according to the symptoms - infertility or recurrent pregnancy loss (RPL). Main outcome measures: were the pregnancy and live birth rate and secondarily the complication rate. Furthermore, the results were analysed depending on the need of assisted reproductive techniques (ART). Results: The treatment has resulted in an overall pregnancy rate of 71% for both groups. The spontaneous pregnancy rate is 45% and 8 pregnancies resulted from ART (26%). The overall first live birth rate is 51.6%. A decrease has been noticed in the miscarriage rate from 95.24% to 24% (p<0.001) in the overall population. Conclusions: In patients with a symptomatic septate uterus hysteroscopic septoplasty is a safe and effective procedure. The favourable results pointing out the benefits of surgery on the reproductive outcomes as well as the relatively simple and safe technique of HS make the intervention attractive.

ABSTRACT

Background: Unhealthy alcohol use is a public health issue, prioritized by the World Health Organization (WHO) for prevention and reduction. Ukraine falls in the highest WHO category of "years of life lost" due to alcohol use. Objective: To investigate perceptions of alcohol consumption in a sample of youth and adults in western Ukraine. Methods: In-depth semi-structured interviews were conducted with 38 adult stakeholders (aged 21-63 years), and 81 adolescents and young adults (aged 12-21 years) completed paper-and-pencil open-ended questions. A combined deductive-inductive thematic analysis of these qualitative data resulted in an initial coding scheme for both parts of the data. These initial codes were organized into patterns, which were further condensed to four themes. Results: The four themes that were developed are: (1) The general historical, socio-economic-political situation and its relation to alcohol use, (2) Alcohol in the home and daily environment, (3) Alcohol use, related feelings, peers, family, and burden to health, and (4) Perceptions of the consequences of alcohol (mis)use. Conclusions: Respondents indicated awareness that daily consumption, also in youth, as well as binge drinking and childhood sipping constitute a risk to health. These risks were described in the context of easy availability, low pricing, and peer pressure. The respondents mentioned awareness that alcohol dependence (AD) of parents affected families with the risk of disadvantageous child development. Interventions may include targeting current norms, stigmatizing beliefs and supporting subjects in developing coping skills.

ABSTRACT

BACKGROUND: Silkmoths and their relatives constitute the ecologically and taxonomically diverse superfamily Bombycoidea, which includes some of the most charismatic species of Lepidoptera. Despite displaying spectacular forms and diverse ecological traits, relatively little attention has been given to understanding their evolution and drivers of their diversity. To begin to address this problem, we created a new Bombycoidea-specific Anchored Hybrid Enrichment (AHE) probe set and sampled up to 571 loci for 117 taxa across all major lineages of the Bombycoidea, with a newly developed DNA extraction protocol that allows Lepidoptera specimens to be readily sequenced from pinned natural history collections. RESULTS: The well-supported tree was overall consistent with prior morphological and molecular studies, although some taxa were misplaced. The bombycid Arotros Schaus was formally transferred to Apatelodidae. We identified important evolutionary patterns (e.g., morphology, biogeography, and differences in speciation and extinction), and our analysis of diversification rates highlights the stark increases that exist within the Sphingidae (hawkmoths) and Saturniidae (wild silkmoths). CONCLUSIONS: Our study establishes a backbone for future evolutionary, comparative, and taxonomic studies of Bombycoidea. We postulate that the rate shifts identified are due to the well-documented bat-moth "arms race". Our research highlights the flexibility of AHE to generate genomic data from a wide range of museum specimens, both age and preservation method, and will allow researchers to tap into the wealth of biological data residing in natural history collections around the globe.

ABSTRACT

OBJECTIVE: Despite being the most important prognostic factor for prolonged overall survival in epithelial ovarian cancer (EOC), the measurement of residual disease is hampered by its subjective character. Additional assessment tools are needed to establish the success of cytoreductive surgery in order to predict patients' prognosis more accurately. The aim of this study is to evaluate the independent prognostic value of perioperative CA125 change in advanced stage EOC patients. STUDY DESIGN: We identified all patients who underwent primary cytoreductive surgery for advanced stage (FIGO IIB-IV) EOC between 2008 and 2015, from the Netherlands Cancer Registry. The relative perioperative change in CA125 was categorized into four groups; increase, <50% decline, 50-79% decline and ≥80% decline. Overall survival (OS) was analyzed using Kaplan-Meier survival curves and multivariable cox regression models. RESULTS: We included 1232 eligible patients with known pre- and postoperative CA125 serum levels. Patients with a decline of ≥80% in CA125 levels experienced improved OS compared to those with a decline of <50% (univariable Hazard Ratio (HR) 0.45, 95%CI 0.36-0.57). The prognostic effect of perioperative CA125 change was independent of patient- and treatment characteristics, such as the extent of residual disease after cytoreductive surgery (multivariable HR≥80% 0.52(0.41-0.66)). CONCLUSIONS: This study shows that the perioperative change in CA125 is an independent prognostic factor for overall survival after primary surgery for EOC patients. This pleads for the use of a combined model, consisting of perioperative CA125 change and the outcome of residual disease, in order to predict the prognosis of EOC patients more accurately.

ABSTRACT

INTRODUCTION: About 5% of ovarian tumours have a non-epithelial histology, including germ cell tumours (GCTs), sex cord-stromal tumours (SCSTs) and sarcomas. Because these non-epithelial ovarian tumours are rare and population-based studies are scarce, the aim of this population-based study is to describe trends in the incidence, treatment and survival of women with these tumours in the Netherlands. METHODS: All women diagnosed with non-epithelial ovarian malignant tumours in the Netherlands between 1989 and 2015 were identified from the Netherlands Cancer Registry. Data on demographics, tumour characteristics and initial treatment were collected, and overall survival was analysed. RESULTS: A total of 1258 non-epithelial ovarian tumours were identified comprising 752 GCTs (60%), 341 SCSTs (27%) and 165 sarcomas (13%). The European age-standardised incidence rate (ESR) was 0.4 per 100,000 persons per year for GCTs, 0.2 for SCSTs and 0.1 for sarcomas. Approximately 97% of patients underwent surgical resection for the primary tumour, 31% received systemic treatment and 3% radiotherapy. Between the late 1980s and 2015, five-year overall survival improved for all histologic subtypes: GCTs rose from 73% to 88% (p = 0.03), SCSTs from 64% to 81% (p = 0.57) and sarcomas from 20% to 29% (p = 0.14). CONCLUSION: Malignant GCTs and SCSTs are rare, and their incidence has not significantly changed over recent decades. They have a good prognosis, which also improved slightly during this period. Primary sarcomas of the ovary are extremely rare and still have a poor prognosis.

ABSTRACT

INTRODUCTION: The care for patients with epithelial ovarian cancer(EOC) is organised in eight different geographical regions in the Netherlands. This situation allows us to study differences in practice patterns and outcomes between geographical regions for patients with FIGO stage IIIC and IV. METHODS: We identified all EOC patients who were diagnosed with FIGO stage IIIC or IV between 01.01.2008 and 31.12.2015 from the Netherlands Cancer Registry. Descriptive statistics were used to summarize treatment and treatment sequence(primary cytoreductive surgery(PCS) or neoadjuvant chemotherapy and interval cytoreductive surgery(NACT-ICS)). Moreover, outcome of surgery was compared between geographical regions. Multilevel logistic regression was used to assess whether existing variation is explained by geographical region and case-mix factors. RESULTS: Overall, 6,741 patients were diagnosed with FIGO IIIC or IV disease. There were no differences in the percentage of patients that received any form of treatment between the geographical regions(range 80-86%, P = 0.162). In patients that received cytoreductive surgery and chemotherapy, a significant variation between the geographical regions was observed in the use of PCS and NACT-ICS(PCS: 24-48%, P < 0.001). The percentage of complete cytoreductive surgeries after PCS ranged from 10 to 59%(P < 0.001) and after NACT-ICS from 37 to 70%(P < 0.001). Moreover, geographical region was independently associated with the outcome of surgery, also when adjusted for treatment sequence(P < 0.001). CONCLUSION: We observed a significant variation in treatment approach for advanced EOC between geographical regions in the Netherlands. Furthermore, the probability to achieve no residual disease differed significantly between regions, regardless of treatment sequence. This may suggest that surgical outcomes can be improved across geographical regions.

ABSTRACT

INTRODUCTION: The ability to minimize residual disease during primary cytoreductive surgery is the strongest predictor for improved overall survival in advanced ovarian cancer. But while the probability to achieve a macroscopic complete resection increases if surgery is preceded by neoadjuvant chemotherapy (NACT), survival rates after NACT are similar to those observed after primary surgery. This may suggest that the prognostic effect of residual disease is altered after NACT. More specifically, randomized data suggest that there is no difference between optimal (0.1-1 cm) and suboptimal (>1 cm) cytoreductive surgery after NACT. Therefore, the aim of the current review is to establish the prognostic effect of the amount of residual disease after interval cytoreductive surgery (ICS) on overall survival. METHODS: Potential articles for inclusion in the current review were systematically searched through Medline, Embase and Cochrane in September 2017. Median overall survival (mOS) was summarized by the outcome of ICS per study. In addition, mOS was summarized for all studies together stratified by the outcome of ICS, based on the principle of a weighted average. RESULTS: In total, 3677 unique manuscripts were individually screened on title and abstract, which resulted in 11 individual studies that comprised a total of 2178 patients. MOS was 41 months for patients with no residual disease (range 33-54 months), 27 months for patients with 0.1-1 cm of residual disease (range 19-38 months) and 21 months with >1 cm of residual disease (range 14-27 months). Six studies showed significant differences between optimal and suboptimal ICS, while five studies showed no differences. CONCLUSION: The summary of the currently available literature showed that after NACT, patients with optimal cytoreductive surgery experience lengthened survival compared to patients with suboptimal cytoreductive surgery. Patients with no macroscopic residual disease have, however, the most favorable survival outcomes, similar to what is seen after primary cytoreductive surgery.

ABSTRACT

Hydrographic data collected from research cruises, bottom-anchored moorings, drifting Ice-Tethered Profilers, and satellite altimetry in the Beaufort Gyre region of the Arctic Ocean document an increase of more than 6,400 km3 of liquid freshwater content from 2003 to 2018: a 40% growth relative to the climatology of the 1970s. This fresh water accumulation is shown to result from persistent anticyclonic atmospheric wind forcing (1997-2018) accompanied by sea ice melt, a wind-forced redirection of Mackenzie River discharge from predominantly eastward to westward flow, and a contribution of low salinity waters of Pacific Ocean origin via Bering Strait. Despite significant uncertainties in the different observations, this study has demonstrated the synergistic value of having multiple diverse datasets to obtain a more comprehensive understanding of Beaufort Gyre freshwater content variability. For example, Beaufort Gyre Observational System (BGOS) surveys clearly show the interannual increase in freshwater content, but without satellite or Ice-Tethered Profiler measurements, it is not possible to resolve the seasonal cycle of freshwater content, which in fact is larger than the year-to-year variability, or the more subtle interannual variations.

ABSTRACT

OBJECTIVE: Treatment for advanced epithelial ovarian cancer (EOC) consists of debulking surgery and (neo)adjuvant platinum-based chemotherapy. The aim of this study was to evaluate whether the time from surgery to adjuvant chemotherapy (TTC) was associated with clinical outcome. METHODS: We identified all Dutch patients who received optimal or complete debulking surgery for primary EOC (FIGO IIb-IV) between 2008 and 2015 from the Netherlands Cancer Registry. TTC was divided into three groups based on the interquartile range (IQR). Early (<25%) and prolonged (>75%) TTC were compared to intermediate TTC (25-75%). Logistic regression was used to identify factors associated with a prolonged TTC and multivariable Cox regression to evaluate the independent effect of treatment interval on overall survival (OS). Patients receiving primary debulking surgery (PDS) and patients receiving interval debulking surgery (IDS) were analyzed separately. RESULTS: 4097 patients were included, 1612 underwent PDS and 2485 IDS. Median TTC was 29 days (IQR 24-37). Age ≥ 65, complete debulking surgery, postoperative complications, and hospitalization ≥10 days were independently associated with a longer TTC for both PDS and IDS. TTC in the longest quartile was associated with poor OS after both PDS (Hazard Rate (HR) 1.43, 95% CI 1.09-1.88) and NACT-IDS (HR 1.22 (1.02-1.47)) when compared to the intermediate TTC, but only in patients with no macroscopic residual disease after surgery. CONCLUSIONS: Our study provides evidence that delayed initiation of adjuvant chemotherapy is an independent prognostic factor for worse overall survival after complete (interval)debulking surgery. We advise to start adjuvant chemotherapy within five to six weeks after debulking surgery.

ABSTRACT

INTRODUCTION: Primary debulking surgery (PDS) followed by adjuvant chemotherapy is historically recommended as first line treatment for advanced stage ovarian cancer. Two randomized controlled trials, however, showed similar efficacy and reduced toxicity with neoadjuvant chemotherapy followed by interval debulking surgery (NACT-IDS). Nevertheless, uptake of NACT-IDS varies widely between hospitals, which cannot be explained by difference in patient populations. In this survey, we therefore aimed to evaluate the views on NACT-IDS among all Dutch gynaecologists and medical oncologists involved in the treatment of ovarian cancer. STUDY DESIGN: An e-mail link to the online questionnaire was sent to all medical oncologists and gynaecologists in the Netherlands, regardless of their (sub)specializations. The data was analysed using descriptive statistics and chi-square tests were used to analyse differences between groups. RESULTS: Three-hundred-forty physicians were invited to fill out the questionnaire. After two reminders, 167 of them responded (49%). Among the responders, 82% of the gynaecologists versus 93% of the medical oncologists considered the available evidence sufficiently convincing to treat advanced stage ovarian cancer patients with NACT-IDS (p = 0.076). Moreover, 33% of gynaecologists and 62% of medical oncologists preferred NACT-IDS to PDS as first line treatment (p = 0.001). While most responders (86%) indicated that selecting the right patients for NACT-IDS is difficult, those with bulky disease, FIGO stage IV or metastases near the porta hepatica were most likely to undergo NACT-IDS. CONCLUSION: The majority of Dutch gynaecologists and medical oncologists adopted NACT-IDS as an alternative treatment approach for advanced stage primary ovarian cancer. About two-thirds of medical oncologists and one-third of gynaecologists prefer NACT-IDS to PDS as first line treatment in this setting. Improving patient selection is considered of paramount importance.

ABSTRACT

AIM: This study investigates changes in therapy and long-term survival for patients with epithelial ovarian cancer (EOC) in the Netherlands. METHODS: All patients with EOC, including peritoneal and fallopian tube carcinoma, diagnosed in the Netherlands between 1989 and 2014 were selected from the Netherlands Cancer Registry. Changes in therapy were studied and related to overall survival (OS) using multivariable Cox regression models. RESULTS: A total of 32,540 patients were diagnosed with EOC of whom 22,047 (68%) had advanced stage disease. In early stage, lymph node dissection as part of surgical staging procedures increased over time from 4% in 1989-1993 to 62% in 2009-2014 (P < 0.001). In advanced stage, the number of patients receiving optimal treatment with surgery and chemotherapy increased from 55% in 1989-1993 to 67% in 2009-2014 (P < 0.001). Five-year survival rates improved in both early stage (74% versus 79%) and advanced stage (16% versus 24%) as well as in all patients combined (31% versus 34%). Ten-year survival rates, however, slightly improved in early stage (62% versus 67%) and advanced stage (10% versus 13%) but remained essentially unchanged at 24% for all patients combined. CONCLUSION: Despite intensified treatment and staging procedures, long-term survival for women with EOC has not improved in the last 25 years. The observed improvements in 5-year OS reflect a more prolonged disease control rather than better chances for cure. Furthermore, the apparent better long-term outcome, when early and advanced stage patients are analysed separately, is largely due to improved staging procedures and the ensuing stage migration. These effects disappear in a combined analysis of all patients.

ABSTRACT

Several species of swallowtail butterflies (genus Papilio) are Batesian mimics that express multiple mimetic female forms, while the males are monomorphic and nonmimetic. The evolution of such sex-limited mimicry may involve sexual dimorphism arising first and mimicry subsequently. Such a stepwise scenario through a nonmimetic, sexually dimorphic stage has been proposed for two closely related sexually dimorphic species: Papilio phorcas, a nonmimetic species with two female forms, and Papilio dardanus, a female-limited polymorphic mimetic species. Their close relationship indicates that female-limited polymorphism could be a shared derived character of the two species. Here, we present a phylogenomic analysis of the dardanus group using 3964 nuclear loci and whole mitochondrial genomes, showing that they are not sister species and thus that the sexually dimorphic state has arisen independently in the two species. Nonhomology of the female polymorphism in both species is supported by population genetic analysis of engrailed, the presumed mimicry switch locus in P. dardanus. McDonald-Kreitman tests performed on SNPs in engrailed showed the signature of balancing selection in a polymorphic population of P. dardanus, but not in monomorphic populations, nor in the nonmimetic P. phorcas. Hence, the wing polymorphism does not balance polymorphisms in engrailed in P. phorcas. Equally, unlike in P. dardanus, none of the SNPs in P. phorcas engrailed were associated with either female morph. We conclude that sexual dimorphism due to female polymorphism evolved independently in both species from monomorphic, nonmimetic states. While sexual selection may drive male-female dimorphism in nonmimetic species, in mimetic Papilios, natural selection for protection from predators in females is an alternative route to sexual dimorphism.

ABSTRACT

RATIONALE: The European Position Paper on Sinusitis (EPOS) guidelines provide composite criteria to evaluate chronic rhinosinusitis (CRS) control, taking into consideration the severity of patients' symptoms, aspect of nasal mucosa and medical intake as parameters of CRS control. OBJECTIVES: To study the degree of CRS control using novel EPOS control criteria at 3-5 years after a functional endoscopic sinus surgery (FESS) and correlate these data to symptoms scores. METHODS: Adult CRS patients (n = 560) who had undergone bilateral FESS for chronic inflammatory sinonasal disease 3-5 years prior to the study were included. Patients received a postal questionnaire asking for control items according to EPOS control criteria, visual analogue scale (VAS) scores for total and individual sinonasal symptoms, sinonasal outcome test (SNOT)-22 and Short Form (SF)-36 questionnaires. MEASUREMENTS AND MAIN RESULTS: About 19.5% of CRS patients were well controlled, with 36.8% of patients being partly controlled and 43.7% uncontrolled. The levels of control corresponded to mean total VAS, SNOT-22 and SF-36 scores. Subgroup analysis revealed that female gender, aspirin intolerance and revision FESS were associated with higher prevalence of uncontrolled CRS, whereas allergy, asthma and smoking status did not alter the percentage of patients in each category of control. In 81 patients attending the outpatient clinic, nasal endoscopy changed classification in only four patients (4.9%). CONCLUSIONS: Based on the novel EPOS control criteria, at least 40% of CRS patients are uncontrolled at 3-5 years after FESS. Therefore, better treatment strategies leading to higher disease control are warranted in CRS care.

ABSTRACT

BACKGROUND: Treatment for allergic rhinitis (AR) aims at reducing the burden of allergic inflammation, either by suppression of the nasal inflammation with pharmacotherapy or by inducing tolerance via immunotherapy (IT). At present, we lack information on the comparison between the degree of symptom control in AR patients treated with IT and those on pharmacotherapy. AIMS: An observational study was conducted evaluating the degree of symptom control, the total and individual nasal symptom severity and current medication use at 3 years after starting either pharmacotherapy or subcutaneous immunotherapy (SCIT) for AR. METHODS: A total number of 800 patients diagnosed with AR between October 2007 and February 2010 at the Ear, Nose and Throat Unit and Allergology Clinical Department of the University Hospitals of KU Leuven, Belgium, were included. Among these patients, 120 had been started on IT at the time of their initial visit, and 680 were prescribed guideline-based pharmacotherapy. In 2013, patients were sent a questionnaire asking for the current severity of nasal symptoms using a visual analogue scale (VAS) score, duration of nasal symptoms and presence or absence of abnormal sleep, impairment of daily activities, sport, leisure, impaired functioning at work/school, troublesome symptoms, and current medication use. A VAS score for total nasal symptoms (TNS) was used to distinguish between controlled and uncontrolled AR. RESULTS: An overall response rate of 54%. At 3 years after the initiation of the treatment, the IT group showed lower VAS scores for TNS than the pharmacotherapy group, with lower percentages of patients having a VAS score of equal or higher than 5. The IT group consisted of more patients with mild AR than the pharmacotherapy group despite the higher percentage of polysensitization at the onset of treatment in the IT group. 18% of the IT patients met the criteria of persistent AR whereas this was 51% amongst non-IT patients. Interestingly, 70% of IT patients did not use any medical treatment for AR anymore, whereas 61% of pharmacotherapy patients were still on medical treatment. CONCLUSIONS: This observational study demonstrates that IT is associated with higher control of AR, reduced symptom severity and reduced medication use at 3 years after the onset of treatment. Therefore, this real-life study reinforces the clinical value of immunotherapy in allergic rhinitis.

ABSTRACT

Afrotropical Acraeini butterflies provide a fascinating potential model system to contrast with the Neotropical Heliconiini, yet their phylogeny remains largely unexplored by molecular methods and their generic level nomenclature is still contentious. To test the potential of mitogenomes in a simultaneous analysis of the radiation, we sequenced the full mitochondrial genomes of 19 African species. Analyses show the potential of mitogenomic phylogeny reconstruction in this group. Inferred relationships are largely congruent with a previous multilocus study. We confirm a monophyletic Telchinia to include the Asiatic Pareba with a complicated paraphylum, traditional (sub)genus Acraea, toward the base. The results suggest that several proposed subgenera and some species groups within Telchinia are not monophyletic, while two other (sub)genera could possibly be combined. Telchinia was recovered without strong support as sister to the potentially interesting system of distasteful model butterflies known as Bematistes, a name that is suppressed in some treatments. Surprisingly, we find that this taxon has remarkably divergent mitogenomes and unexpected synapomorphic tRNA rearrangements. These gene order changes, combined with evidence for deviating dN/dS ratios and evidence for episodal diversifying selection, suggest that the ancestral Bematistes mitogenome has had a turbulent past. Our study adds genetic support for treating this clade as a distinct genus, while the alternative option, adopted by some authors, of Acraea being equivalent to Acraeini merely promotes redundancy. We pave the way for more detailed mitogenomic and multi-locus molecular analyses which can determine how many genera are needed (possibly at least six) to divide Acraeini into monophyletic groups that also facilitate communication about their biology.

ABSTRACT

Draf III frontal sinusotomy: influence of patient characteristics on outcome. OBJECTIVE: To identify positive and negative predictive outcome factors for the Draf III procedure based on the experience of a single center. METHODS: Seventy-two patients who underwent a Draf III procedure between 2005 and 2011 at the ENT department of University Hospitals Leuven were included. Patient demographics, history of frontal sinus surgery, clinical features, and computed tomographic evaluations were reviewed and analyzed for associations with symptom control and endoscopic outcome. RESULTS: The mean age was 48 years (16-82 years), and the male-to-female-ratio was 2:1. Major indications were chronic rhinosinusitis (with or without nasal polyps) and mucoceles. Supplementary frontal (recess) cells were found in the majority of patients. Osteoneogenesis was present in one out of four patients. At the end of follow-up (mean 35 months), the neo-ostium patency rate was 89%. Stenosis or closure of the neo-ostium was seen in 11% of patients, and 15% of patients required revision surgery. Subjective improvement was reported by 88%. CONCLUSION: The results of Draf III frontal sinusotomy were positive in the long term. Previous frontal sinus surgery, the presence of allergy or aspirin-exacerbated respiratory disease (AERD), asthma, smoking, and variants in frontal recess anatomy did not affect outcome. Osteoneogenesis and chronic mucosal inflammation could be controlled by creating a large drainage pathway.

ABSTRACT

BACKGROUND: Over-treatment of estrogen receptor positive (ER+), lymph node-negative (LNN) breast cancer patients with chemotherapy is a pressing clinical problem that can be addressed by improving techniques to predict tumor metastatic potential. Here we demonstrate that analysis of second harmonic generation (SHG) emission direction in primary tumor biopsies can provide prognostic information about the metastatic outcome of ER+, LNN breast cancer, as well as stage 1 colorectal adenocarcinoma. METHODS: SHG is an optical signal produced by fibrillar collagen. The ratio of the forward-to-backward emitted SHG signals (F/B) is sensitive to changes in structure of individual collagen fibers. F/B from excised primary tumor tissue was measured in a retrospective study of LNN breast cancer patients who had received no adjuvant systemic therapy and related to metastasis-free survival (MFS) and overall survival (OS) rates. In addition, F/B was studied for its association with the length of progression-free survival (PFS) in a subgroup of ER+ patients who received tamoxifen as first-line treatment for recurrent disease, and for its relation with OS in stage I colorectal and stage 1 lung adenocarcinoma patients. RESULTS: In 125 ER+, but not in 96 ER-negative (ER-), LNN breast cancer patients an increased F/B was significantly associated with a favorable MFS and OS (log rank trend for MFS: p = 0.004 and for OS: p = 0.03). On the other hand, an increased F/B was associated with shorter PFS in 60 ER+ recurrent breast cancer patients treated with tamoxifen (log rank trend p = 0.02). In stage I colorectal adenocarcinoma, an increased F/B was significantly related to poor OS (log rank trend p = 0.03), however this relationship was not statistically significant in stage I lung adenocarcinoma. CONCLUSION: Within ER+, LNN breast cancer specimens the F/B can stratify patients based upon their potential for tumor aggressiveness. This offers a "matrix-focused" method to predict metastatic outcome that is complementary to genomic "cell-focused" methods. In combination, this and other methods may contribute to improved metastatic prediction, and hence may help to reduce patient over-treatment.

ABSTRACT

Phenotypic plasticity describes the ability of an individual to alter its phenotype in response to the environment and is potentially adaptive when dealing with environmental variation. However, robustness in the face of a changing environment may often be beneficial for traits that are tightly linked to fitness. We hypothesized that robustness of some traits may depend on specific patterns of plasticity within and among other traits. We used a reaction norm approach to study robustness and phenotypic plasticity of three life-history traits of the collembolan Orchesella cincta in environments with different thermal regimes. We measured adult mass, age at maturity and growth rate of males and females from heath and forest habitats at two temperatures (12 and 22 °C). We found evidence for ecotype-specific robustness of female adult mass to temperature, with a higher level of robustness in the heath ecotype. This robustness is facilitated by plastic adjustments of growth rate and age at maturity. Furthermore, female fecundity is strongly influenced by female adult mass, explaining the importance of realizing a high mass across temperatures for females. These findings indicate that different predicted outcomes of life-history theory can be combined within one species' ontogeny and that models describing life-history strategies should not assume that traits like growth rate are maximized under all conditions. On a methodological note, we report a systematic inflation of variation when standard deviations and correlation coefficients are calculated from family means as opposed to individual data within a family structure.

ABSTRACT

Gestational trophoblastic diseases include placental pathologies comprising fertilization abnormalities (hydatidiform moles) and malignant lesions (choriocarcinoma, placental site trophoblastic tumor and epithelioid trophoblastic tumor). Due to their low incidence and heterogeneity, their diagnosis, management and treatment are not always optimal. Following the example of other European countries, a national registration system with two reference centers has been set up to guide physicians and patients and to propose individualized management. The centers offer their expertise through a systematic centralised pathology review by a panel of experts. HCG values are plotted in regression curves. In case of gestational trophoblastic neoplasia, an imaging work-up is proposed, from which the FIGO score and stage are derived and will guide the choice of treatment. Belgian centers offer a multidisciplinary approach, in partnership with the referent physician. More information for practitioners and patients is available on a web site: www.mole-chorio-bgog.eu, which also harbours a forum of discussion.
