RESUMO
OBJECTIVES: To report the perinatal outcomes of high-risk asymptomatic women who attended a specialist preterm surveillance clinic (PSC) to undergo screening for spontaneous preterm birth (PTB) in Ireland. METHODS: Single center, retrospective cohort study of asymptomatic high risk women who attended the PSC between January 2019 and December 2022. A comprehensive database of all patients who attended the clinic during the study period was constructed and analyzed. Overall outcomes were reported, and stratified per the occurrence of preterm or term birth. Iatrogenic PTBs were included in the outcome data. RESULTS: Following exclusions for loss-to-follow-up, 762 cases were analyzed, constituting 2262 PSC visits. Of those, 183 women were prescribed progesterone (24.0 %), and 100 women underwent cervical cerclage (13.1 %) to prevent spontaneous PTB. Overall, 2.4 %, 6.2 % and 18.6 % of participants gave birth prior to 30 weeks, 34 weeks, and 37 weeks, respectively. The median gestational age at birth for the entire cohort was 38.6 weeks (inter-quartile range (IQR) 37.2-39.6 weeks). Women who delivered < 37 weeks were significantly more likely to be smokers (p = 0.030), have a previous spontaneous PTB (p = 0.016), have multiple pregnancies (p < 0.001), type 1 or 2 diabetes (p = 0.044), or have a previous full dilatation caesarean section birth (p = 0.024). Infants born prior to 37 weeks were more likely to have a lower median birthweight (2270 vs 3300 g, p < 0.001), be admitted to a neonatal intensive care unit (53.8 % vs 2.3 %, p < 0.001) or experience short-term morbidity, including respiratory support (38.0 % vs 1.6 %, p < 0.001). CONCLUSIONS: Over 80% of women deemed to be at high risk of PTB gave birth at term gestations following attendance at a PSC during pregnancy. Most women can be successfully managed without interventions, instead employing a policy of serial cervical surveillance, to identify those at greatest risk of PTB.

OBJECTIVE: To validate externally the QUiPP App v.2 algorithms in an independent cohort of high-risk asymptomatic women attending a preterm birth (PTB) surveillance clinic in Ireland. METHODS: This was a retrospective, single-center, observational study assessing discrimination and calibration of the QUiPP App v.2 at six predetermined clinical timepoints (PTB at < 30, < 34 and < 37 weeks of pregnancy and PTB within 1, 2 and 4 weeks of testing). Discrimination was assessed by estimating the area under the receiver-operating-characteristics curve (AUC) and sensitivity at fixed false-positive rates of 5%, 10% and 20%. Model calibration was assessed to evaluate the concordance between expected and observed outcomes. P-values < 0.05 were considered statistically significant. No adjustments for treatment effects were made. RESULTS: Overall, 762 women with 1660 PTB surveillance clinic visits using the QUiPP App v.2 between 2019 and 2022 were analyzed. The study population included 142 (18.6%) patients who later experienced PTB. The QuiPP App's performance in the prediction of short-term outcomes, such as birth within 1 week (AUC, 0.866 (95% CI, 0.755-0.955)), 2 weeks (AUC, 0.721 (95% CI, 0.569-0.854)) and 4 weeks (AUC, 0.775 (95% CI, 0.699-0.842)), and delivery at < 30 weeks (AUC, 0.747 (95% CI, 0.613-0.865)), was superior to its ability to predict longer-term outcomes (PTB at < 37 weeks: AUC, 0.631 (95% CI, 0.596-0.668)). Calibration was generally good for low-risk results, as the predicted risk in these patients tended to match the observed incidence. However, in women deemed to be at greater risk of PTB, the predicted probability superseded the observed incidence of PTB. CONCLUSIONS: The QUiPP App v.2 accurately discriminates women who are at short-term risk of PTB. A 'treatment paradox' may influence calibration in high-risk women. Further research is needed to ascertain if QuiPP treatment thresholds can be safely adjusted in women receiving prophylactic treatment to prevent PTB, and whether this improves the outcome. © 2024 The Authors.

BACKGROUND: Quality control material (QCM) for hematology in veterinary laboratories is limited, and repeat patient testing quality control (RPT-QC) is an alternative method using excess matrix-specific samples. OBJECTIVES: This study aimed to determine if median differences between RPT-QC analyses for each time interval for RBC, HGB, HCT, and WBC were the same, determine if unified RPT-QC limits can be applied to a network of veterinary laboratories, compare the performance of RPT-QC to commercial QCM for the reference analyzer and evaluate the experience over a 4 month period and design, improve and implement an automated spreadsheet for RPT-QC data management. METHODS: The potential to unify individual analyzer RPT-QC limits for red blood cells (RBC), hematocrit (HCT), hemoglobin (HGB), and white blood cells (WBC) on multi-site Sysmex XT-2000-iV analyzers was explored by a difference of means test and confidence interval determination for the median difference for each network analyzer in comparison to the network reference analyzer. User experience of an automated RPT-QC data management Excel spreadsheet was collected by user feedback during monthly meetings. Numbers of out-of-control results and the root causes for these for RPT-QC were compared against those of a commercial QCM over a 4-month period. RESULTS: Differences between individual analyzer RPT-QC limits were too large to allow for unification of network limits. The automated spreadsheet successfully highlighted out-of-control events for RPT-QC. Trends or shifts were more frequent for commercial QCM based on observed performance and a 1-2.5 s QC rule than for RPT-QC. Following routine troubleshooting, RPT-QC out-of-control events were resolved with an alternative RPT-QC sample indicating random error associated with excessive deterioration. Use of an automated spreadsheet for recording RPT-QC, documentation and troubleshooting of out-of-control events, and collating monthly summary calculations were considered an asset in laboratory quality management. CONCLUSIONS: RPT-QC can be successfully implemented and integrated into a multi-site veterinary laboratory. Individual analyzer RPT-QC limit generation is recommended. The deterioration of commercial QCM caused shifts or trends in QC results, which initiated more repeat analyses and investigations than did RPT-QC.

BACKGROUND: There is little information on the effectiveness of introducing age restriction legislation alone to reduce the rate of sunbed usage by teenagers. Prior to the Public Health (Sunbed) Act of 2014 prohibiting the use of sunbeds in under 18-year-olds in Ireland we reported the rate of sunbed use at 7.5%. OBJECTIVES: The aim of the study was to compare the rate of sunbed usage among Irish teenagers before and after the introduction of banning legislation to determine if it had the desired effect of reducing its rate of use. METHODS: In a cross-sectional survey, students from the same schools as in our previous study completed an anonymous, written questionnaire pertaining to sunbed usage. RESULTS: In total, 783 questionnaires, from 13 schools across Ireland, were completed. The rate of sunbed use in the current study was 7.2%, compared to 7.5% in the pre-ban study, (P = 0.76). A higher rate of sunbed use was observed in Dublin schools and female public students. CONCLUSION: Our study suggests that legislation alone is ineffective at reducing sunbed usage in a teenage population. A multifaceted approach is required that includes enforcement of the legislation together with targeted public education and awareness campaigns using all aspects of the media.

OBJECTIVE: Increased fetal size is associated with shoulder dystocia during labor and subsequent need for assisted delivery. We sought to investigate if increased fetal adiposity diagnosed sonographically in late pregnancy is associated with increased risk of operative delivery. METHODS: This secondary analysis of the Genesis Study recruited 2392 nulliparous women with singleton pregnancy in cephalic presentation, in a prospective, multicenter study, to examine prenatal and intrapartum predictors of Cesarean delivery. Participants underwent ultrasound and clinical evaluation between 39 + 0 and 40 + 6 weeks' gestation. Data on fetal biometry were not revealed to patients or to their managing clinicians. A fetal adiposity composite of fetal thigh adiposity and fetal abdominal wall thickness was compiled for each infant in order to determine whether fetal adiposity > 90th centile was associated with an increased risk of Cesarean or operative vaginal delivery. RESULTS: After exclusions, data were available for 2330 patients. Patients with a fetal adiposity composite > 90th centile had a higher maternal body mass index (BMI) (25 ± 5 kg/m2 vs 24 ± 4 kg/m2 ; P = 0.005), birth weight (3872 ± 417 g vs 3585 ± 401 g; P < 0.0001) and rate of induction of labor (47% (108/232) vs 40% (834/2098); P = 0.048) than did those with an adiposity composite ≤ 90th centile. Fetuses with adiposity composite > 90th centile were more likely to require Cesarean delivery than were those with adiposity composite ≤ 90th centile (P < 0.0001). After adjusting for birth weight, maternal BMI and need for induction of labor, fetal adiposity > 90th centile remained a risk factor for Cesarean delivery (P < 0.0001). A fetal adiposity composite > 90th centile was more predictive of the need for unplanned Cesarean delivery than was an estimated fetal weight > 90th centile (odds ratio, 2.20 (95% CI, 1.65-2.94; P < 0.001) vs 1.74 (95% CI, 1.29-2.35; P < 0.001). Having an adiposity composite > 90th centile was not associated with an increased likelihood of operative vaginal delivery when compared with having an adiposity composite ≤ 90th centile (P = 0.37). CONCLUSIONS: Fetuses with increased adipose deposition are more likely to require Cesarean delivery than are those without increased adiposity. Consideration should, therefore, be given to adding fetal thigh adiposity and abdominal wall thickness to fetal sonographic assessment in late pregnancy. Copyright © 2019 ISUOG.

BACKGROUND: Significant health disparities exist between members of the Travelling community and those of the general population. Barriers to Traveller engagement with health services include the experience or perception of discrimination, and cultural and health literacy barriers. Experience of skin disease and interactions with healthcare providers has not been widely explored in this ethnic minority. The formation of positive relationships between the Travelling community and healthcare providers is important in the promotion of treatment adherence and improving health outcomes. OBJECTIVES: To investigate Travellers' experience of skin disease and their relationships with healthcare providers. METHODS: Focus groups were conducted with a purposive sample of female members of the Irish Travelling community with experience of skin health issues, between January 2018 and April 2018. Three focus groups were conducted at three separate locations with 10 participants in each group. Themes were identified from the focus group transcripts using an inductive thematic analysis framework. RESULTS: Emergent themes surrounding relationships between Travellers and healthcare providers included health literacy, discrimination, information inconsistency, trust and communication. Factors that were valued in the creation of positive relationships included an appreciation of varying degrees of health literacy, the provision of sufficient information tailored to an individual's needs and a demonstration of cultural competence. CONCLUSIONS: Dermatologists are well placed to provide practical, customized, treatment guidance and engage patients while integrating their culturally based beliefs.

OSIRIS-REx will return pristine samples of carbonaceous asteroid Bennu. This article describes how pristine was defined based on expectations of Bennu and on a realistic understanding of what is achievable with a constrained schedule and budget, and how that definition flowed to requirements and implementation. To return a pristine sample, the OSIRIS-REx spacecraft sampling hardware was maintained at level 100 A/2 and <180 ng/cm2 of amino acids and hydrazine on the sampler head through precision cleaning, control of materials, and vigilance. Contamination is further characterized via witness material exposed to the spacecraft assembly and testing environment as well as in space. This characterization provided knowledge of the expected background and will be used in conjunction with archived spacecraft components for comparison with the samples when they are delivered to Earth for analysis. Most of all, the cleanliness of the OSIRIS-REx spacecraft was achieved through communication among scientists, engineers, managers, and technicians.
RESUMO
PURPOSE: Rates of trauma patients presenting with history of prior trauma range from 25 to 44%. Outcomes involving recidivists in the setting of intentional trauma, especially penetrating trauma, are conflicting. We hypothesized that if violence does escalate with successive incidence, then injuries due to successive violence should escalate or become increasingly severe with successive admissions. METHODS: The trauma registry from an urban level I adult and pediatric trauma center was queried for injuries due to blunt assault, stabbing, and firearm injury. Primary outcome measures were mortality, injury mechanism, and injury severity for each successive trauma admission. RESULTS: Victims of blunt assault and stabbing were more likely to become recidivists than victims of gun violence (OR 1.53, p < 0.001 and OR 1.57, p < 0.001). Violent re-injury became increasingly severe only in victims of repeated gun violence. Patients with gunshot as the mechanism at every admission are at highest risk for mortality (OR 13.48, p < 0.001). All but one mortality (95.8%) in the recidivist population occurred within 180 days of discharge from a prior injury. CONCLUSION: Recidivism for interpersonal violence results in a significant number of admissions to trauma centers. In our patient cohort, injury associated with successive blunt assaults did not worsen with subsequent admissions. Recidivism for gunshot wounds tends to be more severe and have a worse prognosis with each successive admission compared to outcomes associated with repeated stab wounds. Focused efforts should include rehabilitation efforts early in the post-injury period, especially in patients with a history of gunshot wounds.

Diarylidenecyclopentanone compound namely, 2,5-bis[4-choloroacetyl-(thiophen-2-ylmethylene)]cyclopentanone (BCTCP) was firstly synthesized using the normal condition of Friedel-Crafts method by reacting 2,5-bis(thiophen-2-ylmethylene)cyclopentanone (BTCP) with chloroacetyl chloride in the presence of aluminum chloride anhydrous. The structure of this compound was confirmed by elemental and spectral analyses including FT-IR, 1H-NMR, 13C-NMR and mass spectrometry. The electronic absorption and emission properties of BCTCP were studied in different solvents. BCTCP displays a slight solvatochromic effect of the absorption and emission spectrum, indicating a small change in dipole moment of BCTCP upon excitation. BCTCP displayed photodecomposition in chlorinated solvents upon irradiating with 365 nm light. Ground and excited states electronic geometric optimizations were performed using density functional theory (DFT) and time-dependent density functional theory (TD-DFT), respectively. A DFT natural bond orbital (NBO) analysis complemented the intramolecular charge transfer (ICT). The simulated maximum absorption and emission wavelengths are in line the observed ones in trend, and were proportionally red-shifted with the increase of the solvent polarity. The stability, hardness and electrophilicity of BCTCP in different solvents were correlated with the polarity of the elected solvents.
RESUMO
A pilot randomized controlled trial that evaluated the effect of remote ischemic preconditioning (RIPC) on clinical outcomes following major vascular surgery was performed. Eligible patients were those scheduled to undergo open abdominal aortic aneurysm repair, endovascular aortic aneurysm repair, carotid endarterectomy, and lower limb revascularization procedures. Patients were randomized to RIPC or to control groups. The primary outcome was a composite clinical end point comprising any of cardiovascular death, myocardial infarction, new-onset arrhythmia, cardiac arrest, congestive cardiac failure, cerebrovascular accident, renal failure requiring renal replacement therapy, mesenteric ischemia, and urgent cardiac revascularization. Secondary outcomes were components of the primary outcome and myocardial injury as assessed by serum troponin values. The primary outcome occurred in 19 (19.2%) of 99 controls and 14 (14.1%) of 99 RIPC group patients (P = .446). There were no significant differences in secondary outcomes. Our trial generated data that will guide future trials. Further trials are urgently needed.

This paper describes the fabrication of oligonucleotide-coated Cy5-doped silica nanoparticles using a combination of multivalent linkers and their use in surface-based DNA sandwich hybridization assays. Dipodal silane is introduced as a means to fabricate amine-coated silica nanoparticles and its advantages compared to monopodal silanes are discussed. The use of dipodal silane in conjunction with three different polymer linkers (oxidized dextran, linear and 8-arm polyethylene glycol (PEG)) to immobilize single-stranded DNA to Cy5-doped nanoparticles is investigated and dynamic light scattering measurements and Fourier transform infrared spectroscopy are used to follow the progression of the functionalization of the nanoparticles. We observe a significant improvement in the binding stability of the single-stranded DNA when the dipodal silane and 8-arm PEG are used in combination, when compared to alternative conjugation strategies. Both 8mer and 22mer oligonucleotides are securely conjugated to the high-brightness nanoparticles and their availability to hybridize with a complementary strand is confirmed using solution-based DNA hybridization experiments. In addition, a full surface-based sandwich assay demonstrates the potential these nanoparticles have in the detection of less than 500 femtomolar of a DNA analogue of micro RNA, miR-451.

The aim of our retrospective study is to report on our experience using the Prevena™ wound system in obese patients undergoing caesarean section delivery. A total of 26 cases were identified from July 2012 to October 2013. The median BMI of these women was 45.3 kg/m(2). Elective caesarean sections were performed in 20 women (77%). There were four cases (15%) of superficial dehiscence. Factors associated with wound breakdown were wound infection (p = 0.03), increasing BMI (p < 0.001) and emergency LSCS (p = 0.04). In a logistic regression model the presence of infection was the only factor which remained associated with wound breakdown. Wound disruption is a major cause of morbidity following caesarean section in morbidly obese patients. The wound complication rate in our experience was low with the Prevena™ dressing with no cases of sheath dehiscence, and no patient required a second operation. The presence of infection is the most important factor in wound breakdown and should be the focus for management protocols.

In the present work, the absorption, emission spectra and dipole moments(µ(g), µ(e)) of N, N-bis (2, 5-di-tert-butylphenyl)-3, 4:9, 10- perylenebis (dicarboximide) (DBPI) have been studied in solvents of various polarities at room temperature. Using the methods of solvatochromism, the difference between the first excited singlet state (µ(e)) and ground state (µ(g)) dipole moments was estimated from Lippert - Mataga,, Bakhshiev, Kawski - Chamma - Viallet equations. The change in dipole moment (Δµ) was also calculated using the variation of the Stokes shift with microscopic solvent polarity parameter (E(T)(N)). It was observed that the value of excited singlet state dipole moment is higher (3.53 Debye) than the ground state one (1.92Debye), showing that the excited state of DBPI is more polar than the ground state.
RESUMO
OBJECTIVE: To construct monochorionic diamniotic (MCDA) and dichorionic diamniotic (DCDA) twin reference ranges for umbilical artery (UA) pulsatility index (PI), UA resistance index (RI), fetal middle cerebral artery (MCA) PI and peak systolic velocity (PSV) and cerebroplacental ratio (CPR) from 24 weeks' to 38 weeks' gestation and compare these with published normal values for singleton pregnancies. METHODS: This prospective multicenter cohort study included 1028 unselected twin pairs recruited over a 2-year period. Participants with dichorionic twins underwent fortnightly ultrasound surveillance from 24 weeks' gestation, with monochorionic twins being followed every 2 weeks from 16 weeks until delivery. A total of 7536 fetal Doppler examinations in 618 twin pregnancies were included in the analysis, with reference ranges for MCDA and DCDA pregnancies constructed for each of the Doppler indices using multilevel modeling. RESULTS: UA-PI and UA-RI appear to be higher in twins than in singletons, and MCA-PI and MCA-PSV appear to be lower. The CPR also appears to be lower in twins than in singletons. Similar MCA indices were observed in MCDA and DCDA twins. CONCLUSION: We have established longitudinal reference ranges for UA-PI and UA-RI, MCA-PI and MCA-PSV and CPR in twin pregnancies, which appear to differ from those in singleton pregnancies. The derived twin-specific reference ranges may be more appropriate in the surveillance of these high-risk pregnancies. Applying the singleton CPR cut-off of ≤ 1.0 may lead to a large number of false-positive diagnoses of cerebral redistribution in twin fetuses.

BACKGROUND: Pre-pregnancy care improves pregnancy outcomes in type 1 diabetes mellitus (T1DM). Continuous subcutaneous insulin infusion (CSII) therapy and multiple daily injection (MDI) therapy can both be used to achieve glycaemic targets, but few data are available to compare their efficacy in pre-pregnancy care. AIM: To compare MDI and CSII in pre-pregnancy care in T1DM. METHODS: Retrospective database review of women with T1DM attending the Dublin Diabetes in Pregnancy Centre. RESULTS: 464 women with T1DM (40 treated with CSII) were included. Women attending for pre-pregnancy care had lower HbA1c levels at booking to antenatal services [52 ± 10 mmol/mol (6.9 ± 0.9 %) vs. 62 ± 16 mmol/mol (7.8 ± 1.5 %), p < 0.001], and booked at an earlier gestation (6 ± 2 vs. 8 ± 6 weeks, p < 0.001). In those who attended for pre-pregnancy care, the CSII group had lower HbA1c levels at booking than those using MDI [48 ± 8 mmol/mol (6.5 ± 0.7 %) vs. 53 ± 10 mmol/mol (7.0 ± 0.9 %), p = 0.03]. Gestational age at delivery and birth weight did not differ between groups. Caesarean section rates were associated with CSII use (p < 0.001), duration of diabetes (p = 0.002), and parity (p = 0.006). Nulliparous women using CSII with a longer history of diabetes were more likely to deliver by Caesarean section. There was no perinatal mortality. CONCLUSIONS: Pre-pregnancy care delivered by a specialist multi-disciplinary team effectively reduces HbA1c levels peri-conception. CSII use results in lower HbA1c levels in pre-pregnancy care in selected individuals and should be considered in women with T1DM planning pregnancy.
