Perineal care and outcomes in a birth center
Objective: to analyse the perineal outcomes in childbirth and post-partum perineal care in a freestanding birth centre.
Method: a cross-sectional study, with data collection performed in the women’s birth records forms from Casa Angela, a freestanding birth centre, São Paulo, Brazil, in 2016-2017 (n=415). The following data was analysed: occurrence and perineal tear degree; maternal, neonatal and birth care-related variables; perineal suture prevalence; complications in wound healing and natural methods on perineal care. Data were subjected to descriptive, inferential and multiple analyses.
Results: in 11.8% of women, the perineum was kept intact, 61.9% had spontaneous first-degree tear and 26.3% had second-degree tear. The variables related to the occurrence and higher spontaneous degree tears were maternal age and second period of childbirth >2 hours. The protective factors against the occurrence and higher degree tears were number of previous vaginal childbirths and maternal position different from vertical during childbirth. Perineal suture was performed in 16.0% and 70.6% of women with spontaneous first- and second-degree tears, respectively. The main perineal complications after birth were edema (53.6%) and pain (29.4%); and the perineal suture increased the chance for these complications (OR=2.5; 95%CI 1.5-4.3). Perineum icepack compress was used in 53.8% of women during post-partum period.
Conclusion: maternal and health-care related factors were associated to the prevalence and degree of spontaneous perineal tear. First-degree spontaneous perineal tears were prevalent and sutured in a low number of women. There were more complications in the wound healing process when the perineal suture was performed, regardless the tear degree. The number of natural methods in post-partum perineal care was higher than the use of medicines

Técnicas de creación y manipulación de imágenes de estructuras orgánicas tridimensionales. Nuevos entornos de aplicación didáctica
The development of computer-generated images opens new perspectives in the field of teaching. These techniques permit geometric modelling of three-dimensional structures, allowing the production and manipulation of real images and the numerical and graphic characterization of two-three-dimensional contours. The procedure proposed is based on the manipulation, by geometric (turns, traslations) and algebraic (addition, intersection) operations, of an initially finite set of surfaces (elipsoids, paraboloids, cylinders and planes), defined by their parameters, for teaching purposes

Complementary and Integrative Health Practices in a Brazilian Freestanding Birth Center: A Cross-Sectional Study
The study aimed to analyze the use of complementary and integrative health practices (CIHPs) during labor and birth in a freestanding birth center. A total of 28 different CIHPs were applied with or used by laboring women. The most adopted CIHPs were mind-body practices (99.9%) and natural products (35.5%), mostly used by primiparous women (P <.05). Adopting CIHPs can increase care quality, increase positive experiences during childbirth, and promote evidence-based choices
Planet-star interactions with precise transit timing. III. Entering the regime of dynamical tides
Hot Jupiters on extremely short-period orbits are expected to be unstable to
tidal dissipation and spiral toward their host stars. That is because they
transfer the angular momentum of the orbital motion through tidal dissipation
into the stellar interior. Although the magnitude of this phenomenon is related
to the physical properties of a specific star-planet system, statistical
studies show that tidal dissipation might shape the architecture of hot Jupiter
systems during the stellar lifetime on the main sequence. The efficiency of
tidal dissipation remains poorly constrained in star-planet systems. Stellar
interior models show that the dissipation of dynamical tides in radiation zones
could be the dominant mechanism driving planetary orbital decay. These
theoretical predictions can be verified with the transit timing method. We
acquired new precise transit mid-times for five planets. They were previously
identified as the best candidates for which orbital decay might be detected.
Analysis of the timing data allowed us to place tighter constraints on the
orbital decay rate. No statistically significant changes in their orbital
periods were detected for all five hot Jupiters in systems HAT-P-23, KELT-1,
KELT-16, WASP-18, and WASP-103. For planets HAT-P-23 b, WASP-18 b, and WASP-103
b, observations show that the mechanism of the dynamical tides dissipation
probably does not operate in their host stars, preventing them from rapid
orbital decay. This finding aligns with the models of stellar interiors of
F-type stars, in which dynamical tides are not fully damped due to convective
cores. For KELT-16 b, the span of transit timing data was not long enough to
verify the theoretical predictions. KELT-1 b was identified as a potential
laboratory for studying the dissipative tidal interactions of inertial waves in
a convective layer.Comment: Accepted for publication in A&
The correlation between immune subtypes and consensus molecular subtypes in colorectal cancer identifies novel tumour microenvironment profiles, with prognostic and therapeutic implications
Background
Solid tumour growth is the consequence of a complex interplay between cancer cells and their microenvironment. Recently, a new global transcriptomic immune classification of solid tumours has identified six immune subtypes (ISs) (C1–C6). Our aim was to specifically characterise ISs in colorectal cancer (CRC) and assess their interplay with the consensus molecular subtypes (CMSs).
Methods
Clinical and molecular information, including CMSs and ISs, were obtained from The Cancer Genome Atlas (TCGA) (N = 625). Immune cell populations, differential gene expression and gene set enrichment analysis were performed to characterise ISs in the global CRC population by using CMSs.
Results
Only 5 ISs were identified in CRC, predominantly C1 wound healing (77%) and C2 IFN-γ dominant (17%). CMS1 showed the highest proportion of C2 (53%), whereas C1 was particularly dominant in CMS2 (91%). CMS3 had the highest representation of C3 inflammatory (7%) and C4 lymphocyte depleted ISs (4%), whereas all C6 TGF-β dominant cases belonged to CMS4 (2.3%). Prognostic relevance of ISs in CRC substantially differed from that reported for the global TCGA, and ISs had a greater ability to stratify the prognosis of CRC patients than CMS classification. C2 had higher densities of CD8, CD4 activated, follicular helper T cells, regulatory T cells and neutrophils and the highest M1/M2 polarisation. C2 had a heightened activation of pathways related to the immune system, apoptosis and DNA repair, mTOR signalling and oxidative phosphorylation, whereas C1 was more dependent of metabolic pathways.
Conclusions
The correlation of IS and CMS allows a more precise categorisation of patients with relevant clinical and biological implications, which may be valuable tools to improve tailored therapeutic interventions in CRC patients.This work was funded by projects DTS15/00157 , PI16/01827 and CIBER-ONC CB16/12/00442 from the Instituto de Salud Carlos III ( Ministry of Economy, Industry and Competitiveness, Spain ) and cofunded by the European Regional Development Fund (ERDF, European Union), and approved by the Ethics Committee or our Institution.

BRAF V600E status may facilitate decision-making on active surveillance of low-risk papillary thyroid microcarcinoma.
Introduction: Conservative active surveillance has been proposed for low-risk papillary thyroid microcarcinoma (PTMC), defined as 641.0 cm and lacking clinical aggressive features, but controversy exists with accepting it as not all such PTMCs are uniformly destined for benign prognosis. This study investigated whether BRAF V600E status could further risk stratify PTMC, particularly low-risk PTMC, and can thus help with more accurate case selection for conservative management. Methods: This international multicenter study included 743 patients treated with total thyroidectomy for PTMC (584 women and 159 men), with a median age of 49 years (interquartile range [IQR], 39-59 years) and a median follow-up time of 53 months (IQR, 25-93 months). Results: On overall analyses of all PTMCs, tumour recurrences were 6.4% (32/502) versus 10.8% (26/241) in BRAF mutation-negative versus BRAF mutation-positive patients (P = 0.041), with a hazard ratio (HR) of 2.44 (95% CI (confidence interval), 1.15-5.20) after multivariate adjustment for confounding clinical factors. On the analyses of low-risk PTMC, recurrences were 1.3% (5/383) versus 4.3% (6/139) in BRAF mutation-negative versus BRAF mutation-positive patients, with an HR of 6.65 (95% CI, 1.80-24.65) after adjustment for confounding clinical factors. BRAF mutation was associated with a significant decline in the Kaplan-Meier recurrence-free survival curve in low-risk PTMC. Conclusions: BRAF V600E differentiates the recurrence risk of PTMC, particularly low-risk PTMC. Given the robust negative predictive value, conservative active surveillance of BRAF mutation-negative low-risk PTMC is reasonable whereas the increased recurrence risk and other well-known adverse effects of BRAF V600E make the feasibility of long-term conservative surveillance uncertain for BRAF mutation-positive PTMC
Reliability and cultural applicability of the Greek version of the International Personality Disorders Examination.
BACKGROUND: The International Personality Disorders Examination (IPDE) constitutes the proposal of the WHO for the reliable diagnosis of personality disorders (PD). The IPDE assesses pathological personality and is compatible both with DSM-IV and ICD-10 diagnosis. However it is important to test the reliability and cultural applicability of different IPDE translations. METHODS: Thirty-one patients (12 male and 19 female) aged 35.25 ± 11.08 years, took part in the study. Three examiners applied the interview (23 interviews of two and 8 interviews of 3 examiners, that is 47 pairs of interviews and 70 single interviews). The phi coefficient was used to test categorical diagnosis agreement and the Pearson Product Moment correlation coefficient to test agreement concerning the number of criteria met. RESULTS: Translation and back-translation did not reveal specific problems. Results suggested that reliability of the Greek translation is good. However, socio-cultural factors (family coherence, work environment etc) could affect the application of some of the IPDE items in Greece. The diagnosis of any PD was highly reliable with phi >0.92. However, diagnosis of non-specfic PD was not reliable at all (phi close to 0) suggesting that this is a true residual category. Dianosis of specific PDs were highly reliable with the exception of schizoid PD. Diagnosis of antisocial and Borderline PDs were perfectly reliable with phi equal to 1.00. CONCLUSIONS: The Greek translation of the IPDE is a reliable instrument for the assessment of personality disorder but cultural variation may limit its applicability in international comparisons

Perineal pain effect on the activities of women who had an episiotomy
Objective: This manuscript discusses the influence of the perineal pain after normal birth on daily activities of women who had an episiotomy.
Methods: Descriptive study with data collected through interviews performed from 20 to 48 hours after delivery, with 52 women, applying the pain numeric scale (0-10).
Results: Perineal pain was present in 86.5% and 82.7% of women, at 20 and 48 hours after delivery, respectively. There was a predominance of mild pain (64.4% to 72.1%), followed by moderate pain (28.9% to 18.6%). The restriction of the activities varied between 92.3% and 86.5% women, from 20 to 48 hours after delivery, respectively.
Conclusions: Although most women had reported mild pain, it was noted that this morbidity limits the essential activities
