51P Interleukina – 6 i rozpuszczalny receptor Interlekiny – 6 u chorych na raka jajnika

Celem pracy była ocena stężeń Interleukina – 6 (IL-6) oraz rozpuszczalnego receptora Interleukiny – 6 (slL-6) u chorych na raka jajnika przed rozpoczęciem leczenia oraz przed 3 kursem leczenia chemicznego oraz odpowiedź na pytanie czy mogą one stanowić czynniki rokowniczy w raku jajnika.Badaniu poddano 20 chorych, leczenie rozpoczęto w Katedrze Onkologii AM w Poznaniu w latach 1990–1996. Leczenie chorych rozpoczęto od rozpoznania nowotworu poprzez pierwotne leczenie operacyjne i następową chemioterapie opartą o analogii platyny. W przypadku chorych pozostających w leczeniu oraz chorych, które znajdują się w całkowitej remisji potwierdzonej histopatologicznie operacja “second-look” obserwację kontynuowano do 36 miesięcy od chwili rozpoczęcia leczenia. W grupie badanej 3 chore miały I stopień klinicznego zaawansowania wg FIGO, natomiast pozostałe III i IV stopień złośliwości zróżnicowania komórkowego, 8 stopień II, a 10 stopień III. Histopatologiczne typy raka jajnika w grupie badanej były następujące: u 8 chorych rozpoznano typ surowiczny, u 5 endometroidalny, u 3 śluzowy, natomiast u pozostałych 4 chorych rozpoznano po jednym typie raka mezonefroidalnego, niezróżnicowanego, adenocarcinoma oraz cystadeno-carcinoma.Do momentu zakończenia obserwacji 13 chorych zmarło z powodu choroby. W chwili zakończenia obserwacji żyje 7 chorych: 5 pozostaje w leczeniu a 2 pod obserwacją bez objawów choroby.U każdej chorej przed rozpoczęciem leczenia operacyjnego oraz przed 3 kursem chemioterapii pobierano krew, którą po skrzepnięciu i odwirowaniu zamrażano do czasu wykonania oznaczeń. Interleukinę-6 (IL-6) oraz rozpuszczalny receptor lnterleukiny-6 (sIL-6) oznaczano za pomocą testów immunoenzymatycznych firmy R&D Systems.Oceniono zmiany w stężeniu powyższych parametrów w zależności od stopnia klinicznego zaawansowania wg FIGO, gradingu, rodzaju przeprowadzonego zabiegu operacyjnego, typu histologicznego nowotworu oraz odpowiedzi na leczenie.Stężenia IL-6 przed rozpoczęciem leczenia operacyjnego u 3 chorych było poniżej 3,13 pg/ml, u 9 nie przekraczało 12,5 pg/ml, a u pozostałych 8 chorych przekraczało 12,5 pg/ml (górna granica normy), natomiast przed 3 kursem chemioterapii u 10 chorych było poniżej 3,13 pg/ml, u 8 nie przekraczało 12,5 pg/ml, a jedynie u 2 przekraczało 12,5 pg/ml.Stężenia slL-6 przed rozpoczęciem leczenia operacyjnego u wszystkich chorych było prawidłowe (14–46 ng/ml) a przed 3 kursen chemioterapii przekraczało normę jedynie u jednej osoby.Obserwowano zmniejszenie się stężenia IL-6 w trakcie leczenia. Średnie stężenie IL-6 przed rozpoczęciem leczenia operacyjnego wynosiło 25,51 pg/ml (min 2,02pg/ml, max 134,25 pg/ml) i uległo zmniejszeniu przed 3 kursem chemioterapii średnio do 4,80 pg/ml (min 0,82 pg/ml, max 30,36 pg/ml) w sposób ststystycznie istotny.Nie obserwowano natomiast żadnych istotnie statystycznie zmian w odniesieniu do slL-6. Średnie stężenie slL-6 przed rozpoczęcie4m. leczenia operacyjnego wynosiło 28,44 ng/ml (min 17,00 ng/ml, max 45,00 ng/ml) i nie uległo w sposób istotny statystycznie zmniejszeniu przed 3 kursem chemioterapii, gdzie średnio wnsiło 28,43 ng/ml (min 19,20 ng/ml, max 50,80 ng/ml).Nie obserwujemy statystycznie istotnych zależności stężeń IL-6 i slL-6 od stopnia klinicznego zaawansowania wg FIGO, gradingu, rodzaju przeprowadzonego zabiegu operacyjnego, typu histologicznego nowotworu oraz odpowiedzi na leczenie

An overview of farming system typology methodologies and its use in the study of pasture-based farming system: a review

The main objective of the paper is to do a critic study of the use of typology methodologies within pasture-based farming systems (PBFS), especially those situated in less favoured areas, showing in each case the more relevant variables or indicators determining the farming system classification. Another objective is to do an overview of the most used farming system typology methodologies in general. First some considerations about the concept of farming system and approaches to its study have been done. Next, the farming system typology methodologies have been showed in general to different farming systems, but addressed preferably to PBFS. The different tools integrated in these methodologies have been considered: sampling methods, sources of data, variables or indicators obtained from available data and techniques of analysis (statistical or not). Methods for farming system classification have been presented (expert methods, analytical methods or a combination of both types). Among the statistical methods, the multivariate analysis has been overall treated, including the principal component analysis and the cluster analysis. Finally, the use of farming system typology methodologies on different pasture-based farming systems has been presented. The most important aspects considered are following: the main objective of the typology, the main animal species, the employed methods of classification and the main variables involved in this classification

Cytomorphology review of 100 newly diagnosed lower-risk MDS patients in the European LeukemiaNet MDS (EUMDS) registry reveals a high inter-observer concordance

Objectives To examine contemporary survival patterns in the general population of patients diagnosed with chronic myeloid leukaemia (CML), and to identify patient groups with less than optimal outcomes. Design Prospective population-based cohort. Setting The UK's Haematological Malignancy Research Network (catchment population 3.6 million, with >2000 new haematological malignancies diagnosed annually). Participants All patients newly diagnosed with CML, from September 2004 to August 2011 and followed up to 31 March 2013. Main outcome measure Incidence and survival. Results With a median diagnostic age of 59 years, the CML age standardised (European) incidence was 0.9/100 000 (95% CIs 0.8 to 0.9), 5-year overall survival was 78.9% (72.3 to 84.0) and 5-year relative survival 88.6% (81.0 to 93.3). The efficacy of treatment across all ages was clearly demonstrated; the relative survival curves for those under 60 and over 60 years being closely aligned. Survival findings were similar for men and women, but varied with deprivation; the age and sex adjusted HR being 3.43 (1.89 to 6.22) for deprivation categories 4–5 (less affluent) versus 1–3 (more affluent). None of these differences were attributable to the biological features of the disease. Conclusions When therapy is freely provided, population-based survival for CML is similar to that reported in clinical trials, and age loses its prognostic significance. However, although most of the patients with CML now experience close to normal lifespans, those living in more deprived areas tend to have poorer outcomes, despite receiving the same clinical care. A significant improvement in overall population outcomes could be achieved if these socioeconomic differences, which may reflect the treatment compliance, could be eliminated

The serum zinc concentration as a potential biological marker in patients with major depressive disorder

Despite many clinical trials assessing the role of zinc in major depressive disorder (MDD), the conclusions still remain ambiguous. The aim of the present clinical study was to determine and comparison the zinc concentration in the blood of MDD patients (active stage or remission) and healthy volunteers (controls), as well as to discuss its potential clinical usefulness as a biomarker of the disease. In this study 69 patients with current depressive episode, 45 patients in remission and 50 controls were enrolled. The zinc concentration was measured by electrothermal atomic absorption spectrometry (ET AAS). The obtained results revealed, that the zinc concentration in depressed phase were statistically lower than in the healthy volunteers [0.89 vs. 1.06 mg/L, respectively], while the zinc level in patients achieve remission was not significantly different from the controls [1.07 vs. 1.06 mg/L, respectively]. Additionally, among the patients achieve remission a significant differences in zinc concentration between group with and without presence of drug-resistance in the previous episode of depression were observed. Also, patients in remission demonstrated correlation between zinc level and the average number of depressive episodes in the last year. Serum zinc concentration was not dependent on atypical features of depression, presence of psychotic symptoms or melancholic syndrome, age, age of onset or duration of disease, number of episodes in the life time, duration of the episode/remission and severity of depression measured by the Hamilton Rating Scale for Depression (HDRS), and the Montgomery-Asberg Depression Rating Scale (MADRS). Concluding, our findings confirm the correlation between zinc deficit present in the depressive episode, and are consistent with the majority of previous studies. These results may also indicate that serum zinc concentration might be considered as a potential biological marker of MDD

Niraparib Maintenance Therapy in Platinum-Sensitive, Recurrent Ovarian Cancer

BACKGROUND Niraparib is an oral poly(adenosine diphosphate [ADP]-ribose) polymerase (PARP) 1/2 inhibitor that has shown clinical activity in patients with ovarian cancer. We sought to evaluate the efficacy of niraparib versus placebo as maintenance treatment for patients with platinum-sensitive, recurrent ovarian cancer. METHODS In this randomized, double-blind, phase 3 trial, patients were categorized according to the presence or absence of a germline BRCA mutation (gBRCA cohort and non-gBRCA cohort) and the type of non-gBRCA mutation and were randomly assigned in a 2: 1 ratio to receive niraparib (300 mg) or placebo once daily. The primary end point was progression-free survival. RESULTS Of 553 enrolled patients, 203 were in the gBRCA cohort (with 138 assigned to niraparib and 65 to placebo), and 350 patients were in the non-gBRCA cohort (with 234 assigned to niraparib and 116 to placebo). Patients in the niraparib group had a significantly longer median duration of progression-free survival than did those in the placebo group, including 21.0 vs. 5.5 months in the gBRCA cohort (hazard ratio, 0.27; 95% confidence interval [CI], 0.17 to 0.41), as compared with 12.9 months vs. 3.8 months in the non-gBRCA cohort for patients who had tumors with homologous recombination deficiency (HRD) (hazard ratio, 0.38; 95% CI, 0.24 to 0.59) and 9.3 months vs. 3.9 months in the overall non-gBRCA cohort (hazard ratio, 0.45; 95% CI, 0.34 to 0.61; P < 0.001 for all three comparisons). The most common grade 3 or 4 adverse events that were reported in the niraparib group were thrombocytopenia (in 33.8%), anemia (in 25.3%), and neutropenia (in 19.6%), which were managed with dose modifications. CONCLUSIONS Among patients with platinum-sensitive, recurrent ovarian cancer, the median duration of progression-free survival was significantly longer among those receiving niraparib than among those receiving placebo, regardless of the presence or absence of gBRCA mutations or HRD status, with moderate bone marrow toxicity.

Diminishing benefits of urban living for children and adolescents’ growth and development

AbstractOptimal growth and development in childhood and adolescence is crucial for lifelong health and well-being1–6. Here we used data from 2,325 population-based studies, with measurements of height and weight from 71 million participants, to report the height and body-mass index (BMI) of children and adolescents aged 5–19 years on the basis of rural and urban place of residence in 200 countries and territories from 1990 to 2020. In 1990, children and adolescents residing in cities were taller than their rural counterparts in all but a few high-income countries. By 2020, the urban height advantage became smaller in most countries, and in many high-income western countries it reversed into a small urban-based disadvantage. The exception was for boys in most countries in sub-Saharan Africa and in some countries in Oceania, south Asia and the region of central Asia, Middle East and north Africa. In these countries, successive cohorts of boys from rural places either did not gain height or possibly became shorter, and hence fell further behind their urban peers. The difference between the age-standardized mean BMI of children in urban and rural areas was &lt;1.1 kg m–2 in the vast majority of countries. Within this small range, BMI increased slightly more in cities than in rural areas, except in south Asia, sub-Saharan Africa and some countries in central and eastern Europe. Our results show that in much of the world, the growth and developmental advantages of living in cities have diminished in the twenty-first century, whereas in much of sub-Saharan Africa they have amplified.</jats:p
