Ciąża w bliźnie po cięciu cesarskim

Pregnancy in the uterine scare after previous caesarean section is the rarest type of ectopic pregnancy. Due to the possibility of life-threatening complications, cesarean scar pregnancy (CSP) needs rapid and proper diagnosis and management. Hereby we present 3 cases of women with CSP, diagnosed and treated at the Department of Gynecology and Obstetrics of Jagiellonian University Medical College, in Krakow, in 2013, as well as literature review.Ciąża w bliźnie po cięciu cesarskim stanowi najrzadszą postać ciąży pozamacicznej. Ze względu na ryzyko wystąpienia zagrażających życiu powikłań wymaga sprawnego rozpoznania oraz leczenia. Poniżej prezentujemy 3 przypadki pacjentek z ciążą w bliźnie po cięciu cesarskim leczonych w Klinice Ginekologii SU w Krakowie w 2013 roku oraz przegląd piśmiennictwa

Vertical transmission of HPV in pregnancy. A prospective clinical study of HPV-positive pregnant women

Introduction: Human papillomavirus (HPV) is the most common sexually transmitted infection. Data reporting vertical transmission of HPV from the mother to the fetus are inconsistent and scant. Vertical transmission may occur by hematogenic route (transplacental), or by ascending contamination, or through the birth canal, which may result in the dreaded and rare laryngeal papillomatosis. Infected sperm at fertilization is a potential route of infection, too. Objective: The objective of the study was to evaluate the rate of vertical transmission of HPV in HPV-positive pregnant women to their newborn infants, as well as the risk factors of HPV vertical transmission. Material and methods: The clinical material was provided by 136 pregnant women, aged 18-45 years. Out of this group, 30 (22.05%) women with abnormal Pap test and positive DNA HPV test were prospectively observed. Neonatal status, i.e. DNA HPV from the nasopharyngeal smear, was recorded in all infants during the perinatal period. The conventional Pap test was performed with the cervix brush in all women. The Bethesda 2011 classification system was applied. Results: An average C Reactive Protein (CRP) concentration in the studied pregnant women was 11.6083 (Std Dev – 12.93). The most frequent cytological findings in the cervical smears from the examined women were ASCUS, n=13 (43.3%), then – LSIL, n=10 (33.3%), HSIL- n=5 (16.7%) and AGC- n=2 (6.7%). In the neonates, the presence of LR HPV DNA was detected in 9 cases (30.0%) and HR HPV DNA in 7 cases (23.3%). Fourteen neonates (46.7%) tested HPV DNA negative in the perinatal period. Conclusions: HPV infection (incidental or chronic) is observed in approximately 22% of pregnant women from the Małopolska province. Neonatal HPV infection in HPV-positive women was observed in 53.3% of the subjects. CRP concentration > 10 mg/dl in the serum of pregnant women statistically significantly (p 0.001) reduces the risk of vertical transmission of HPV from the mother to the fetus

The SysteMHC Atlas project.

Mass spectrometry (MS)-based immunopeptidomics investigates the repertoire of peptides presented at the cell surface by major histocompatibility complex (MHC) molecules. The broad clinical relevance of MHC-associated peptides, e.g. in precision medicine, provides a strong rationale for the large-scale generation of immunopeptidomic datasets and recent developments in MS-based peptide analysis technologies now support the generation of the required data. Importantly, the availability of diverse immunopeptidomic datasets has resulted in an increasing need to standardize, store and exchange this type of data to enable better collaborations among researchers, to advance the field more efficiently and to establish quality measures required for the meaningful comparison of datasets. Here we present the SysteMHC Atlas (https://systemhcatlas.org), a public database that aims at collecting, organizing, sharing, visualizing and exploring immunopeptidomic data generated by MS. The Atlas includes raw mass spectrometer output files collected from several laboratories around the globe, a catalog of context-specific datasets of MHC class I and class II peptides, standardized MHC allele-specific peptide spectral libraries consisting of consensus spectra calculated from repeat measurements of the same peptide sequence, and links to other proteomics and immunology databases. The SysteMHC Atlas project was created and will be further expanded using a uniform and open computational pipeline that controls the quality of peptide identifications and peptide annotations. Thus, the SysteMHC Atlas disseminates quality controlled immunopeptidomic information to the public domain and serves as a community resource toward the generation of a high-quality comprehensive map of the human immunopeptidome and the support of consistent measurement of immunopeptidomic sample cohorts

Pathways to care for people for dementia: an international multi-centre study

Objective: the aim of the present study was to characterize the clinical pathways that people with dementia (PwD) in different countries follow to reach specialized dementia care. Methods: we recruited 548 consecutive clinical attendees with a standardized diagnosis of dementia, in 19 specialized public centers for dementia care in 15 countries. The WHO “Encounter Form”, a standardized schedule that enables data concerning basic socio-demographic, clinical and pathways data to be gathered, was completed for each participant. Results: the median time from the appearance of the first symptoms to the first contact with specialist dementia care was 56 weeks. The primary point of access to care was the general practitioners (55.8%). Psychiatrists, geriatricians and neurologists represented the most important second point of access. In about a third of cases, PwD were prescribed psychotropic drugs (mostly antidepressants and tranquillizers). Psychosocial interventions (such as psychological counselling, psychotherapy and practical advice) were delivered in less than 3% of situations. The analyses of the ‘pathways diagram’ revealed that the path of PwD to receiving care is complex, diverse across countries, and that there are important barriers to clinical care. Conclusions: the study of pathways followed by PwD to reach specialized care has implications for the subsequent course and the outcome of dementia. Insights into local differences in the clinical presentations and the implementation of currently available dementia care are essential to develop more tailored strategies for these patients, locally, nationally and internationally

Measurement of the Positive Muon Anomalous Magnetic Moment to 0.46 ppm

We present the first results of the Fermilab Muon g-2 Experiment for the positive muon magnetic anomaly $a_\mu \equiv (g_\mu-2)/2$. The anomaly is determined from the precision measurements of two angular frequencies. Intensity variation of high-energy positrons from muon decays directly encodes the difference frequency $\omega_a$ between the spin-precession and cyclotron frequencies for polarized muons in a magnetic storage ring. The storage ring magnetic field is measured using nuclear magnetic resonance probes calibrated in terms of the equivalent proton spin precession frequency ${\tilde{\omega}'^{}_p}$ in a spherical water sample at 34.7$^{\circ}$C. The ratio $\omega_a / {\tilde{\omega}'^{}_p}$, together with known fundamental constants, determines $a_\mu({\rm FNAL}) = 116\,592\,040(54)\times 10^{-11}$ (0.46\,ppm). The result is 3.3 standard deviations greater than the standard model prediction and is in excellent agreement with the previous Brookhaven National Laboratory (BNL) E821 measurement. After combination with previous measurements of both $\mu^+$ and $\mu^-$, the new experimental average of $a_\mu({\rm Exp}) = 116\,592\,061(41)\times 10^{-11}$ (0.35\,ppm) increases the tension between experiment and theory to 4.2 standard deviationsComment: 10 pages; 4 figure
