Take Two: Second Systolic Blood Pressure Provides Prognostic Information in Trauma

Abstract Introduction: An initial systolic blood pressure (SBP1) of <110 mmHg has been shown to predict mortality. However, SBP1 may not reflect hemodynamic changes during initial resuscitation. We aimed to determine if the second recorded blood pressure (SBP2) could provide additional prognostic value. Methods: An 8-year retrospective chart review was performed including patients who underwent trauma activations at a single institution. The initial systolic blood pressure (SBP 1) and second systolic blood pressure (SBP 2) were analyzed. Difference between the first and second systolic blood pressure (ΔSBP) was defined as SBP2 − SBP1. The primary outcome was inhospital mortality, and the secondary outcome was receipt of ≥2 units of blood in the first 4 h of admission. Univariable analysis and logistic regression analysis were performed to assess the relationship of SBP2 and ΔSBP with the study outcomes. Regression model fit was assessed by the likelihood ratio test and Akaike information criterion. Results: Eight thousand seven hundred and ninety-eight patients were included with 12% and 13% presenting with SBP1 <110 mmHg and SBP2 <110 mmHg, respectively. Four hundred and six (5%) died and 327 (4%) received ≥2 units of blood in the first 4 h. The addition of ΔSBP to regression models improved model fit in explaining the primary and secondary outcomes. Subgroup analysis found that the addition of ΔSBP improved model fit for those with penetrating mechanism of injury and those with Injury Severity Score of ≥9, but not for those with blunt moderate or severe traumatic brain injury. Conclusion: SBP2 offers additional prognostic value in predicting trauma outcomes. Incorporating subsequent hemodynamic data during resuscitation beyond the initial SBP in trauma databases should be considered.

Intraosseous and Intravenous Epinephrine Administration Routes in Out-of-Hospital Cardiac Arrest: Survival and Neurologic Outcomes.

The rate of survival after out-of-hospital cardiac arrest varies depending on the timeliness and effectiveness of prehospital interventions. This study was conducted to compare out-of-hospital cardiac arrest outcomes between intravenous and intraosseous routes and between upper and lower extremity routes for drug administration. We retrospectively analyzed data (collected using the Utstein template) from 1220 patients who had experienced out-of-hospital cardiac arrest in Taiwan's Taoyuan City between January 2021 and August 2023. The patients were stratified into intravenous and intraosseous groups by treatment approach and upper and lower extremity access groups by access site. The study outcomes were survival to discharge, favorable neurologic outcomes (Cerebral Performance Category score 1 or 2), and survival for >2 hours. The study groups were statistically compared before and after propensity score matching. Significant pre-propensity score matching differences were observed between intravenous and intraosseous groups, and the aforementioned study outcomes were better in the intravenous group than in the intraosseous group. However, the between-group differences became nonsignificant after propensity score matching. Furthermore, lower extremity access and delayed epinephrine administration were associated with worse outcomes. Survival rates fell below 12.6% when time to treatment exceeded 15 minutes, particularly in the cases of intraosseous access and lower extremity access. This study highlights the benefits of early intervention and upper extremity access for drug administration in patients with out-of-hospital cardiac arrest. Intraosseous access may serve as a viable alternative to intravenous access. Timely administration of essential drugs during resuscitation can improve clinical outcomes and thus has implications for emergency medical service training.

Evolving Computer Science Education Research in Teaching and Learning: A Bibliometric Analysis

This study performed a bibliometric analysis of computer science education (CSE) publications in teaching and learning. The research trend in computer science education was analysed using publications from the Scopus-indexed database between 1970 and 2021. This study aims to summarize this information to assist three groups of stakeholders: educators, researchers and policymakers. Our review goal to document and analyse the trends in CSE research publications for teaching and learning. A total of 800 publications were derived for further assessment based on computer science education in the article title with multiple tools. We used, Microsoft Excel, VOSviewer and Harzing’s Publish or Perish were utilized for frequency analysis data visualization and citation metrics and assessment. The study outcomes were documented with standard bibliometric indicators: publication growth, authorship trends, collaboration, prolific authors, national contribution, most active establishments, top-cited articles, preferred journals, intellectual structure and topical trends. Resultantly, CSE research publications have perpetually grown for the past 51 years since 1970 with the United States highlighting the largest study contributor, followed by Germany and the United Kingdom. The ACM SIGCSE Bulletin published the highest number of CSE research publications. The analysis of the cluster on topical trends indicates that curriculum design and implementation (e.g., assessment, broadening participation), elements of teaching and learning (e.g., constructivism, e-learning, game-based learning) and other areas of interest comprise pedagogical approach (e.g., computational thinking, k-12 education, motivation). Based on the research results, we expand on the findings and propose how authors might enhance the CSE function in curriculum design, implementation and shifts could eventually substitute past study clusters.

COVID-19 vaccination modified the effect of nirmatrelvir-ritonavir on post-acute mortality and rehospitalization: a retrospective cohort study.

While previous research examined coronavirus disease 2019 (COVID-19) antiviral-vaccine interactions through exploratory subgroup analysis, none specifically designed for examining this interaction or its impact on post-acute outcomes. This study examined the interaction between nirmatrelvir-ritonavir and complete COVID-19 vaccination on reducing the risk of post-acute outcomes among COVID-19 patients. We followed COVID-19 patients hospitalized between 11 March 2022 and 10 October 2023, until 31 October 2023 in Hong Kong. Exposure groups were based on nirmatrelvir-ritonavir usage and vaccination status (fully or not fully vaccinated). Post-acute death and all-cause rehospitalization were the study outcomes. Propensity score weighting was applied to balance covariates among exposure groups, including age, sex, Charlson Comorbidity Index, and concomitant treatments. Multiplicative and additive interactions between nirmatrelvir-ritonavir and vaccination status were assessed. A total of 50,438 COVID-19 patients were included in this study and arranged into four exposure groups. Significant additive interaction on post-acute rehospitalization was observed (relative excess risk, 0.10; 95% CI, 0.02-0.19; p-value, 0.018; attributable proportion, 0.07; 95% CI, 0.01-0.12; p-value, 0.017; synergy index, 1.26; 95% CI, 1.02-1.55; p-value, 0.032). The interaction on post-acute mortality was marginally significant. In the subgroup analysis, the interaction effect is more pronounced in older adults, female, and CoronaVac recipients. In conclusion, our study demonstrated an additive interaction between nirmatrelvir-ritonavir and complete vaccination on post-acute outcomes, suggesting greater long-term benefits of the antiviral for fully vaccinated individuals compared to not fully vaccinated patients.

Association between tumour somatic mutations and venous thromboembolism in the 100,000 Genomes Project cancer cohort: a study protocol

Venous thromboembolism (VTE) is a common cause of morbidity and mortality in patients with cancer. There is evidence that specific aberrations in tumour biology contribute to the pathophysiology of this condition. We plan to examine the association between tumour somatic mutations and VTE in an existing cohort of patients with cancer, who were enrolled to the flagship Genomics England 100,000 Genomes Project. Here, we outline an a-priori analysis plan to address this objective, including details on study cohort selection, exposure and outcome definitions, annotation of genetic variants and planned statistical analyses. We will assess the effect of 1) deleterious somatic DNA variants in each gene; 2) tumour mutational burden and 3) tumour mutational signatures on the rate of VTE (outcome) in a pan-cancer cohort. Sensitivity analyses will be performed to examine the robustness of any associations, including adjustment for potentially correlated co-variates: tumour type, stage and systemic anti-cancer therapy. We hope that results from this study may help to identify key genes which are implicated in the development of cancer associated thrombosis, which may shed light on related mechanistic pathways and/or provide data which can be integrated into genetic risk prediction models for these patients.

Methylphenidate and Atomoxetine in Pregnancy and Possible Adverse Fetal Outcomes: A Systematic Review and Meta-Analysis.

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurobehavioral disorders, and it afflicts about 7% of young people. As a consequence, many young women might be pregnant while taking medication for ADHD, but data about safety have not yet been strictly examined. To examine adverse effects in offspring of mothers receiving treatment with atomoxetine and methylphenidate during pregnancy. Electronic databases (PubMed, Embase, and PsycINFO) were searched for articles published through December 31, 2023, with the following search terms: (atomoxetine OR methylphenidate) AND (pregnancy). Observational studies (eg, cohort studies, case-control studies, case-crossover studies, cross-sectional studies, and registry-based studies) that reported offspring outcomes in pregnancy with atomoxetine and/or methylphenidate and in mothers with ADHD but unexposed to ADHD treatment during pregnancy or from the general population were included. Ten studies of 656 records satisfied criteria. Two independent reviewers performed data extraction according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Meta-analyses were conducted based on reported odds ratios (ORs) and corresponding 95% CIs using a linear random effects model. Each study was inversely weighted by the reported variance of the estimators. Risk of publication bias and analysis of heterogeneity through univariate and multivariate metaregressions were also rated. Data were analyzed from January to March 2024. Study outcomes included miscarriages and congenital anomalies. Ten studies involving 16 621 481 pregnant women, 30 830 of them affected by ADHD, were included. Congenital anomalies or miscarriages were not more frequent in offspring of mothers receiving treatment with methylphenidate or atomoxetine during pregnancy compared with unexposed offspring (OR, 1.14; 95% CI, 0.83-1.55; P = .41; I2 = 8% for congenital anomalies; OR, 1.01; 95% CI, 0.70-1.47; P = .96; I2 = 0% for miscarriages) or compared with the general population (OR, 1.19; 95% CI, 0.93-1.53; P = .16; I2 = 74% for congenital anomalies; OR, 1.05, 95% CI, 0.81-1.37; P = .70; I2 = 0% for miscarriage). Evidence from this meta-analysis, which involves a substantial sample of pregnant women with and without ADHD, suggests the maintenance of methylphenidate or atomoxetine during pregnancy is safe, given that congenital anomalies and miscarriages did not appear to significantly increase. Further studies are recommended to support and confirm these findings.

Comparison of outcomes of index and interval laparoscopic cholecystectomy in mild biliary pancreatitis.

Objective: To compare the outcomes of index and interval laparoscopic cholecystectomy in mild biliary pancreatitis in terms of duration of hospital stay. Study Design: Randomized Controlled Trial. Setting: Surgical Unit 1, Holy Family Hospital, Rawalpindi. Period: January 2023 till June 2023. Methods: Patients were being admitted with acute biliary pancreatitis and undergoing either index or interval cholecystectomy. BISAP scoring system was used for severity of ABP and mild cases were included. Study outcomes in both groups (index and interval cholecystectomy) were determined. For quantitative variables mean and standard deviation were calculated. Frequency and percentages were used to describe qualitative variables. Results: Total of 70 patients divided into two groups were included in this study. Mean age of the study population was 40.44+/-7.90 years. Fifty-three percent of the population had BMI in the overweight category. Mean BISAP score was 1.11+/-0.80. All of the patients included in the study had mild acute pancreatitis. The length of hospital stay was significantly associated with timing of surgery with p-values 0.045. Conclusion: The surgical outcomes of index and interval cholecystectomy in acute mild biliary pancreatitis are comparable. However, early cholecystectomy has shorter duration of hospital stay.

A repeated gonadotropin-releasing hormone agonist trigger improves pregnancy outcomes of frozen-thawed embryo transfer in GnRH antagonist cycles: a retrospective propensity-matched score analysis.

To evaluate whether co-treatment of repeated GnRHa triggers with GnRH antagonist protocols can improve the clinical outcomes in in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET) procedures. In this retrospective study, 712 Chinese Han women aged 20-42 undergoing autologous IVF/ICSI-ET with a flexible GnRH antagonist protocol were analyzed. The 735 cycles were split into the single (n = 238) and the repeated (n = 497) GnRHa groups. In the single GnRHa group, 0.2mg of triptorelin was given for oocyte maturation, whereas in the repeated GnRHa group, two doses of 0.2mg were administered 12h apart. PSM design was used for a fair comparison. The main study outcomes included the clinical pregnancy rate (CPR), live birth rate (LBR), good-quality embryo rate, and fertilization rate. Multivariate logistic regression analyses were used to identify all potential factors affecting clinical outcomes. Post-PSM, analysis of 159 cycles per group showed the repeated GnRHa group outperforming the single GnRHa group in IVF fertilization rates (71.5% vs. 67.7%, P < 0.05) and good-quality embryo rate (47.1% vs. 43.7%, P < 0.05). Furthermore, the repeated GnRHa group achieved higher CPR (72.6% vs. 53.4%, P < 0.05) and LBR (59.7% vs. 43.8%, P < 0.05) in FET cycles. Multivariate logistic regression indicated a significant negative correlation between the use of a single GnRHa trigger and both clinical pregnancy (OR = 0.382, P < 0.05) and live birth (OR = 0.518, P < 0.05). Our study reported that individuals who received a repeated GnRHa trigger exhibited higher CPR and LBR during FET cycles compared to those who received a single dose GnRHa trigger.

Effectiveness of a Combination of Nasturtium Herb and Horseradish Root (Angocin® Anti-Infekt N) Compared to Antibiotics in Managing Acute and Recurrent Urinary Tract Infections: A Retrospective Real-world Cohort Study

Background: The goal of this study was to evaluate whether the medical recommendation of Angocin® Anti-Infekt N, compared to standard antibiotic treatment shortly after the diagnosis of a urinary tract infection (UTI) or cystitis, is negatively associated with an early, sporadic, or recurrent UTI, subsequent antibiotic prescriptions, pyelonephritis as a renal complication, or UTI-associated sick leave. Methods: This retrospective cohort study was based on data from the IQVIATM Disease Analyzer database and included patients diagnosed with acute UTI or cystitis by physicians in Germany between 2005 and 2021, who were prescribed either Angocin® or standard antibiotics within 4 days after diagnosis. Patients prescribed antibiotics were matched to those prescribed Angocin® (5:1) using propensity scores. Univariable logistic and Cox regression models were used to investigate the association between Angocin® prescription and the defined study outcomes. The effects of Angocin® were adjusted for age, sex, insurance status, index diagnosis, and physician specialty. Results: A total of 2277 Angocin® patients and 11,385 antibiotic patients were available for analysis. Compared to antibiotic prescriptions, Angocin® prescription was associated with significantly lower odds of an early relapse within 1–30 days after the index date (odds ratio (OR): 0.74; 95% confidence interval (CI): 0.62–0.87; p &lt; 0.001), further sporadic UTI within 31–365 days after the index date (OR: 0.68; 95% CI: 0.58–0.78; p &lt; 0.001), and recurrent UTI (OR: 0.63; 95% CI: 0.48–0.82; p &lt; 0.001). This was also accompanied by reduced antibiotic prescriptions (1–30 days: OR: 0.63; 95% CI: 0.53–0.74, p &lt; 0.001; 31–365 days: OR: 0.56; 95% CI: 0.49–0.64, p &lt; 0.001). A strong, but due to the low incidence, not significant, negative association was observed between Angocin® prescription and the occurrence of pyelonephritis (hazard ratio (HR): 0.67; 95% CI: 0.43–1.06; p = 0.073). Conclusions: The results of this real-world data study demonstrate that Angocin® can be an effective therapeutic option for managing acute and recurrent UTIs and serves as an alternative therapy to antibiotics.

Effectiveness and safety of elexacaftor/tezacaftor/ivacaftor treatment in children aged 6-11 years with cystic fibrosis in a real-world setting.

Elexacaftor-tezacaftor-ivacaftor (ETI) is a highly effective cystic fibrosis (CF) transmembrane conductance regulator (CFTR) modulating therapy for people with CF and at least one F508del variant. However, there is limited data about the safety and efficacy of this therapy in pediatric populations and in real-world settings. This study aimed at evaluating the effectiveness, tolerability, and safety of ETI in children with CF. This was a prospective observational study including all children aged 6-11 years who initiated ETI therapy between October 2022 and March 2023 at the Pediatric CF Center of Milan (Italy). Study outcomes included changes in sweat chloride concentration, FEV1, LCI2.5, body mass index(BMI), tolerance, and safety. Mean changes in study outcomes from baseline through 24 weeks were estimated using mixed-effects regression models. The study included 34 children with CF (median age: 8.3 years). At Week 12, we observed an average decrease in LCI2.5 of 2.3 units (95% confidence interval [CI]: -3.1; -1.5). At Week 24, sweat chloride concentration decreased by 63 mEq/L (95% CI: -69; -58), FEV1 increased by 8.8 percentage point (95% CI: 3.7; 13.9) and BMI increased by 0.15 standard deviation scores (95% CI: 0.04; 0.25). Skin rashes appeared in 6 patients which spontaneously resolved within a few days. One month after treatment initiation, one patient experienced an elevation in liver function test results, which subsequently decreased during follow-up visits without necessitating discontinuation of therapy. Our data indicate that ETI therapy is well tolerated by children with CF and is effective in improving signs of lung function abnormalities from early childhood.

Impact of Discontinuing Both Hypertonic Saline and Dornase Alfa after Elexacaftor-Tezacaftor-Ivacaftor in Cystic Fibrosis.

Rationale: Evaluating approaches to reduce treatment burden is a research priority among people with cystic fibrosis on highly effective modulators, including elexacaftor-tezacaftor-ivacaftor (ETI). Objectives: We sought to evaluate the impact of discontinuing both hypertonic saline (HS) and dornase alfa (DA) versus continuing both therapies among a subgroup of participants in the SIMPLIFY study who sequentially participated in trials evaluating the independent clinical effects of discontinuing HS and DA. Methods: SIMPLIFY participants ≥12 years old on ETI and constituting a subgroup using both HS and DA at study entry were randomized to the HS or DA trial and then randomized 1:1 to continue or discontinue the applicable therapy for 6 weeks. After completion of the first trial, eligible participants could enroll in the second trial beginning with a 2-week run-in. Study outcomes were compared across the duration of SIMPLIFY participation between a cohort remaining on both therapies during SIMPLIFY and a cohort that sequentially discontinued both as a result of trial randomizations. Multivariable regression models were used to estimate treatment differences, adjusted for time between trials, trial order, baseline age, sex at birth, and percent predicted forced expiratory volume in 1 second (ppFEV1) at study entry. Results: Forty-three participants discontinued both therapies by the end of SIMPLIFY, and 63 remained on both, with overall average ppFEV1 of 96.7% at study entry and 3.9 months as the average duration of follow-up from beginning of the first trial to completion of the second trial, including time between trials. No clinically meaningful difference in the change in ppFEV1 from baseline to completion of the second trial was observed between those who discontinued and those who remained on both therapies (difference: 0.22% off-on; 95% confidence interval = -1.60, 2.03). Changes in lung clearance index at 2.5% starting concentration, patient-reported outcomes, and safety outcomes were also comparable. Patient-reported treatment burden, as measured by a Cystic Fibrosis Questionnaire-Revised subscale, significantly decreased in those who discontinued both therapies. Conclusions: SIMPLIFY participants who sequentially discontinued both HS and DA experienced no meaningful changes in clinical outcomes and reported decreased treatment burden as compared with those who remained on both therapies. These data continue to inform a new era of postmodulator care of people with cystic fibrosis.

Clinical outcomes of conversion surgery after induction immunochemotherapy for borderline resectable T4 esophageal squamous cell carcinoma

BackgroundThe current treatment strategies for borderline resectable esophageal squamous cell carcinoma remain controversial. This study aimed to evaluate the efficacy and safety of programmed cell death 1 inhibitors combined with chemotherapy, followed by conversion surgery, for borderline resectable esophageal squamous cell carcinoma.MethodsPatients with borderline resectable esophageal squamous cell carcinoma treated with induction immunochemotherapy from January 1, 2020 to July 1, 2023 at our hospital were retrospectively analyzed. The primary study outcome was the R0 resection rate. Secondary study outcomes included progression-free survival (PFS), overall survival (OS), pathological complete remission (pCR) rate, and safety.ResultsForty patients with borderline resectable esophageal squamous cell carcinoma were included in the analysis. The R0 resection rate was 23/40 (57.5%); the conversion success rate was 27/40 (67.5%), and the pCR rate was 11/40 (27.5%). The median follow-up was 23.6 months (95% CI, 19.1–28.2). One-year OS and PFS rates were 77.7% and 71.8%, respectively. The incidence rate of Grade 3–4 adverse events was 10%. There was a significant difference in PFS between patients who underwent surgery and those who did not (P = 0.008, HR: 0.144 95%CI: 0.034–0.606). However, the difference in OS was not significant (P = 0.128, HR: 0.299 95%CI: 0.063–1.416). Patients who achieved clinical downstaging after induction therapy had significantly better OS (P = 0.004 h: 0.110 95%CI: 0.025–0.495) and PFS (P = 0.0016, HR: 0.106 95%CI: 0.026–0.426) compared to those who did not.ConclusionsConversion surgery after induction immunochemotherapy is a promising new strategy with a high conversion rate, inspiring R0 resection rate, significant pathological remission rate, and mild toxicity for borderline resectable esophageal squamous cell carcinoma.

Creating online, inclusive spaces for learning: ‘Study Together’ with the personal learning advice service

There is a wealth of scholarship on the benefits of synchronous writing sessions for staff and students in higher education (Kornhaber et al., 2016; Eardley et al., 2021; Morley and Aston, 2023). In the Personal Learning Advice (PLA) Service at the Open University UK (OU), we developed bespoke, online study spaces for students from groups currently underrepresented in higher education – known as ‘Study Together’ sessions. The sessions prioritise students from minoritised ethnic groups, students with disabilities, and students with mental health needs who are at risk of poorer study outcomes. This presentation charted the development of Study Together in response to student feedback and evaluation and sought to show the value of ‘targeted’ invitations to engage students with spaces for learning development. Our presentation began by outlining the rationale for a 2022-23 Study Together pilot and its impact on community and belonging for students with mental health declarations (Lavery et al., 2023). We shared our approach to hosting Study Together and the techniques used to create an inclusive, productive study space; we showed how these approaches allowed us to incorporate timed study bursts and reflective practice, building positive study habits among students. Finally, we presented findings from the evaluation of Study Together in 2023-24 and situated this within the wider literature on the benefits of virtual communities of practice for learning. Our presentation spoke directly to the ALDcon24 theme ‘Building inclusive learning development spaces’ and invited delegates to consider the place of virtual, guided study spaces in their own practice.

Short-term outcomes of oropharyngeal administration of colostrum in preterm neonates: a double-blind placebo-controlled randomized trial.

The oropharyngeal administration of colostrum (OAC) in neonates has several benefits. To investigate the short-term outcomes of OAC in preterm neonates. We performed this two-arm, double-blind, placebo-controlled randomized trial at a tertiary neonatal center in Iran in 2021-2023. The intervention and control arms received 0.2 mL of their mother's colostrum or distilled water via oropharyngeal administration every 6 h for 3 days starting from birth until 72 h of age. The main study outcomes were neonatal death, the incidence of necrotizing enterocolitis (NEC), sepsis, retinopathy of prematurity (ROP), length of hospital stay, and period to full enteral feeding. A regression analysis was used to adjust for possible confounders. A total of 126 neonates (mean gestational age, 30.05 weeks) were randomized to the intervention and placebo groups (n=63 each) and had a mean ± SD weight of 1247 ± 193 vs 1156 ± 215 g (P=0.013) and 1- and 5-min Apgar scores of 6.35 vs 5.38 (P=0.003) and 7.84 vs 7.13 (P=0.001), respectively. The mortality rate was 12.7% in the intervention group versus 14.3% in the placebo group (P=0.794). The NEC rate was significantly lower in the intervention versus placebo arm (11.1% vs. 28.6%, respectively; P=0.010), as was the clinically suspected sepsis rate (15.9% vs. 39.7%, respectively; P=0.004). The ROP and bronchopulmonary dysplasia rates did not differ significantly between groups after the adjustment for confounders. The mean length of hospital stay was shorter in the intervention group (26.1 vs. 37.32; P=0.023). Moreover, the mean duration of antibiotic therapy and period to full feeding were significantly shorter in the intervention group. OAC could effectively decrease the incidence of complications in preterm infants and facilitate earlier patient discharge.

A Protocol for the Validation of Novel Sham Acupuncture in Patients Who Have Had a Stroke

Background: A sham control group enhances the quality of clinical trials by controlling for the placebo effect. To ensure rigorous blinding to enhance the quality of clinical trials on acupuncture treatment it is important to develop a more sophisticated sham needle. Discrepancies in perceived needling sensation and treatment expectations between patients and healthy volunteers may affect study outcomes. Thus, it may be inappropriate to generalize the findings of a sham needle validation study in healthy adults to patients who have had a stroke. Therefore, this is a protocol for a clinical trial in patients who have had a stroke to validate a newly developed sham needle to be used in double-blind trials.Methods: Sixty-six patients who have had a stroke will be randomly assigned to the verum or sham needle group using a 1:1 ratio. As the verum and sham needles are identical in appearance, both participants and practitioners will be unaware of the needle type used for acupuncture treatment. After the acupuncture procedure, the participants will be asked whether they believe they received the verum or sham acupuncture treatment and indicate penetration, pain, and de qi sensation for each acupuncture point. A between-group comparison of needle-related adverse events will be performed.Discussion: This double-blind randomized controlled trial will be the first study to validate a newly developed sham acupuncture needle for patients who have had a stroke. The results of this study may inform clinical trial study design for acupuncture treatment of patients who have had a stroke.

Cancer chemotherapy in pregnancy and adverse pediatric outcomes: a population-based cohort study.

Administration of chemotherapy during pregnancy is often delayed, while preterm delivery is common. If in utero exposure to chemotherapy is associated with adverse pediatric outcomes, it is unknown whether that relationship is directly attributable to the chemotherapy or is mediated by preterm birth. Cases were identified from Canadian cancer registries and administrative data in Alberta, British Columbia, and Ontario, 2003-2017, with follow-up until 2018. The primary exposure was receipt of chemotherapy during pregnancy. Severe neonatal morbidity and mortality (SNM-M), neurodevelopmental disorders and disabilities (NDDs) and pediatric complex chronic conditions (PCCC) reflected short- and long-term pediatric outcomes. Modified Poisson and Cox proportional hazard regression models generated adjusted risk ratios (RR) and hazard ratios (HR), respectively. The influence of preterm birth on the association between exposure to chemotherapy in pregnancy and each study outcome was explored using mediation analysis. Of the 1150 incident cases of cancer during pregnancy, 142 (12.3%) received chemotherapy during pregnancy. Exposure to chemotherapy in pregnancy was associated with a higher risk of SNM-M (RR 1.67, 95% CI: 1.13-2.46), but not NDD (HR 0.93, 95% CI: 0.71-1.22) or PCCC (HR 0.96, 95% CI: 0.80-1.16). Preterm birth <34 and <37 weeks mediated 75.8% and 100% of the observed association between chemotherapy and SNM-M, respectively. Most children born to people with cancer during pregnancy appear to have favourable long-term outcomes, even following exposure to chemotherapy in pregnancy. However, preterm birth is quite common, and may contribute to increased rates of adverse neonatal outcomes.

Outcomes of different anesthesia techniques in nonagenarians treated with mechanical thrombectomy for anterior circulation large vessel occlusion: An inverse probability weighting analysis.

There is a lack of evidence for the optimal type of anesthesia technique in patients ⩾ 90 years with acute ischemic stroke undergoing mechanical thrombectomy (MT) as this subgroup of patients was often excluded or under-represented in previous trials. We aimed to compare outcomes between general anesthesia (GA) and non-GA techniques in patients ⩾ 90 years with large vessel occlusion (LVO) undergoing MT. Our study included patients ⩾ 90 years with anterior circulation LVO, NIHSS ⩾ 6, ASPECTS ⩾ 5 consecutively treated with MT within 6 h after stroke onset in three thrombectomy capable centers between January 1st, 2016 and March 30th, 2023. Inverse probability weighting (IPW) was used to reduce bias by indication of the anesthesia type on study outcomes. We used a weighted ordinal robust logistic regression analysis to explore the primary outcome of modified Rankin Scale (mRS) shift at 90 days in GA versus non-GA treated patients. Secondary outcomes included 90-day mortality, symptomatic intracranial hemorrhage (sICH) and TICI score of 2b, 2c, or 3. We included 139 patients ⩾ 90 years treated with MT, 62 were in GA group and 77 in non-GA group. There was a significant shift for worse mRS scores at 90-day in non-GA treated patients (cOR 3.65, 95% CI 1.77-7.77, p = 0.001). The weighted logistic regression showed that non-GA technique was an independent predictor of 90-day mortality (OR 7.49, 95% CI 2.00-28.09; p = 0.003). Our study indicated that nonagenarians with acute ischemic stroke treated with MT without GA have a worse prognosis than their counterparts undergoing MT with GA. Further studies in larger cohorts are warranted to evaluate the optimal type of anesthesia in this patient population.

Association of body roundness index with female infertility: 2013–2018 NHANES

AimThis study aims to understand the association between body roundness index (BRI) and female infertility prevalence. Infertility is a public health concern with significant implications for individuals’ well-being and rights.MethodsAll individuals who completed the National Health and Nutrition Examination Survey (NHANES) between 2013 and 2018 were initially included in this cross-sectional study. Following the screening, 2,777 eligible participants were selected for analysis from the original pool of 10,375 participants. Trained operators conducted anthropometric measurements, including height, weight, and waist circumference. The BRI was then calculated based on established research. Data from infertility status questionnaires were gathered from the NHANES database for all participants, with self-reported infertility serving as the study outcome. Multivariable logistic regression and restricted cubic splines (RCS) were employed to investigate the relationship between BRI and infertility. Subgroup analyses were also conducted to further explore the association between BRI and infertility.ResultsUpon analyzing the baseline characteristics of all women in the study, notable distinctions were identified in the clinical and demographic features between fertile and infertile women. Our investigation revealed a positive correlation between BRI and the likelihood of infertility in both weighted and unweighted multiple logistic regression models. Additionally, BRI exhibited a significant association with infertility in both continuous and categorical forms. Utilizing RCS curves, we noted a linear escalation in the prevalence of infertility with rising BRI values. Subgroup analyses provided further clarity on these observations.ConclusionOur study demonstrates a statistically significant positive correlation between BRI and the prevalence of infertility across diverse populations, suggesting potential implications for infertility prevention and treatment. Future prospective cohort studies will explore this association and understand the underlying mechanisms.

Minimally Invasive Sinus Augmentation: A Systematic Review.

Technology improvement and a better understanding of sinus anatomy and wound healing in the past decade have allowed the development of minimally invasive surgical techniques. This systematic review focused on identifying and describing these techniques for vertical and lateral sinus augmentation (VSA and LSA). Electronic and hand search were conducted to screen the literature published from January 2003 to May 2024. The selected studies had to include detailed techniques for minimally invasive SA. Data extraction included the study types, sample size, technique/instrument details, and outcome measurements. A total of 36 articles (27 VSA, 8 LSA with an additional 1 article included both procedures) with 2732 sinus augmentation met the inclusion criteria. Minimally invasive VSA includes the use of modified rotary instruments with stopper, balloon, hydraulic pressure, digital planning, endoscope, and operating microscope. These techniques aim for conservative flap reflection, precise sinus window preparation, and/or controlled sinus membrane elevation. Most of the selected studies (n = 15) did not report the incidence of sinus membrane perforation. Within the limitations of this review, minimally invasive VSA and LSA achieved sufficient sinus augmentation and implant success with the potential advantages of reduced surgical complications and morbidity. Comparative studies with defined outcomes are encouraged to further validate these useful minimally invasive techniques for SA.
