Background: Research indicates an inconsistent relationship between age and the prevalence of premature ejaculation (PE), with studies reporting an increase, decrease, or no change with age. Aim: To reexamine the possible relationship between age and PE prevalence, implementing methodological improvements that enhance the likelihood of detecting real effects. Methods: From a sample of 2772 men, we analyzed a subset of 418 classified as having probable or definite PE based on the Premature Ejaculation Diagnostic Tool. We not only analyzed men with lifelong PE (LPE; n = 316) and acquired PE (APE; n = 102) separately but assessed prevalence differences across age groups using an omnibus measure to establish PE status and specific PE diagnostic criteria, individually and in multifactorial combination. Outcome: Prevalence of PE in younger vs older men. Results: LPE, but not APE, showed age-related differences in prevalence, with LPE being lower in the higher age group. This pattern was most discernible when a multifactorial approach was used to establish PE status. Clinical Translation: Older men may be less distressed about their dysfunction or may benefit from diminishing ejaculatory function with age. Strengths and Limitations: This cross-sectional study used an improved methodology to detect age-related differences in PE prevalence. Future studies would benefit from a larger sample size that enables a breakdown of prevalence using a greater number of age categories. Conclusion: According to an improved methodology, men with LPE showed a decline in prevalence with aging. A methodology aimed at exploring this relationship should-at the very least-not only distinguish between LPE and APE subtypes but also consider using a multifactorial method of determining PE status that includes a measure of bother/distress.
ABSTRACT
BACKGROUND: To construct a nomogram for predicting necrotizing enterocolitis (NEC) in preterm infants. METHODS: A total of 4,724 preterm infants who were admitted into 8 hospitals between April 2019 and September 2020 were initially enrolled this retrospective multicenter cohort study. Finally, 1,092 eligible cases were divided into training set and test set based on a 7:3 ratio. A univariate logistic regression analysis was performed to compare the variables between the two groups. Stepwise backward regression, LASSO regression, and Boruta feature selection were utilized in the multivariate analysis to identify independent risk factors. Then a nomogram model was constructed based on the identified risk factors. RESULTS: Risk factors for NEC included gestational diabetes mellitus, gestational age, small for gestational age, patent ductus arteriosus, septicemia, red blood cell transfusion, intravenous immunoglobulin, severe feeding intolerance, and absence of breastfeeding. The nomogram model developed based on these factors showed well discriminative ability. Calibration and decision curve analysis curves confirmed the good consistency and clinical utility of the model. CONCLUSIONS: We developed a nomogram model with strong discriminative ability, consistency, and clinical utility for predicting NEC. This model could be valuable for the early prediction of preterm infants at risk of developing NEC.
ABSTRACT
Fetal inflammatory response syndrome or infection after preterm premature rupture of membranes (PPROM) increases neonatal morbidity in preterm deliveries. Biochemical markers from the amniotic fluid (AF) have been used to evaluate possible intra-amniotic infection during the asymptomatic phase after PPROM. This study aimed to describe whether soluble urokinase-type plasminogen activator receptor (suPAR) or procalcitonin (PCT) from AF or maternal sera could reveal fetal inflammatory response or infection after PPROM. AF and maternal serum samples were collected weekly after PPROM (23+ 0 - 34+ 6 gestational weeks) until delivery from twenty women and two women with possible chorioamnionitis with intact membranes. Levels of suPAR, PCT, interleukin-6 (IL-6), glucose, lactate dehydrogenase (LDH), and bacterial PCR were determined from AF and suPAR and PCT and IL-6 from maternal sera. Fetal infection or inflammation response were determined by the histology of the placenta after delivery. AF glucose was significantly lower and AF LDH higher in the fetal site histologic chorioamnionitis (HCA) group, while AF suPAR concentrations tended to be higher in this group. AF suPAR correlated significantly with AF glucose and LDH. Based on receiver operating characteristic (ROC) analysis, AF glucose had the best predictability for fetal site histological chorioamnionitis. The findings of AF PCT were insignificant considering HCA. AF glucose had the highest accuracy in predicting fetal site histologic chorioamnionitis. AF suPAR may be a promising marker; however, our findings were limited by a small study population.
ABSTRACT
BACKGROUND: Poor sleep quality is now a cause of sexual dysfunction. AIM: To investigate variations in sleep quality among patients with different types of premature ejaculation (PE) and a control group. METHODS: Patients with PE were categorized into groups according to 4 types: lifelong (LPE), acquired (APE), variable (VPE), and subjective (SPE). Basic demographic information about the participants was first collected, and then clinical data were obtained. OUTCOMES: Outcomes included the 5-item International Index of Erectile Function, Premature Ejaculation Diagnostic Tool, 7-item Generalized Anxiety Disorder, 9-item Patient Health Questionnaire, Pittsburgh Sleep Quality Index, self-estimated intravaginal ejaculation latency time (minutes), and sleep monitoring parameters obtained from a wearable device (Fitbit Charge 2). RESULTS: A total of 215 participants were enrolled in the study, of which 136 patients with PE were distributed as follows: LPE (31.62%), APE (42.65%), VPE (10.29%), and SPE (15.44%). Subjective scales showed that patients with APE were accompanied by a higher prevalence of erectile dysfunction, anxiety, and depression, as well as poorer sleep quality (assessed by the Pittsburgh Sleep Quality Index). The results of objective sleep parameters revealed that average durations of sleep onset latency (minutes) and wake after sleep onset (minutes) in patients with APE (mean ± SD; 20.03 ± 9.14, 55 ± 23.15) were significantly higher than those with LPE (15.07 ± 5.19, 45.09 ± 20.14), VPE (13.64 ± 3.73, 38.14 ± 11.53), and SPE (14.81 ± 4.33, 42.86 ± 13.14) and the control group (12.48 ± 3.45, 37.14 ± 15.01; P < .05). The average duration of rapid eye movement (REM; minutes) in patients with APE (71.34 ± 23.18) was significantly lower than that in patients with LPE (79.67 ± 21.53), VPE (85.93 ± 6.93), and SPE (80.86 ± 13.04) and the control group (86.56 ± 11.93; P < .05). Similarly, when compared with the control group, patients with LPE had significantly longer durations of sleep onset latency and wake after sleep onset and a significantly shorter duration of REM sleep. CLINICAL IMPLICATIONS: Our study suggests that clinicians should pay attention not only to male physical assessment but also to mental health and sleep quality. STRENGTHS AND LIMITATIONS: This study suggests that changes in sleep structure occur in patients with PE, which may provide some direction for future research. However, the cross-sectional study design does not allow us to conclude that sleep is a risk factor for PE. CONCLUSION: After controlling for traditional parameters such as age, erectile dysfunction, anxiety, and depression, sleep parameters are independently associated with PE. Patients with APE and LPE show significant alterations in sleep parameters, with patients with APE having notably poorer sleep quality, whereas patients with VPE and SPE have sleep parameters similar to controls.
ABSTRACT
BACKGROUND: Premature ventricular contractions (PVCs) can lead to impairment of left ventricular function. The noninvasive myocardial work technique, which incorporates left ventricular afterload, represents a new method for assessing left ventricular functional. AIM: The aim of this study is to explore the value of noninvasive myocardial work technique in assessing left ventricular systolic function in patients with PVCs. METHODS: Compare the clinical data, two-dimensional echocardiography parameters, and myocardial work parameters of 66 patients with PVCs and 35 healthy volunteers and explore the relevant risk factors for postoperative recurrence in patients with PVCs. RESULTS: In patients with PVCs compared to the control group, they exhibit enlargement of left atrial diameter (LAD) and left ventricular internal dimension in diastole (LVIDd), as well as thickening of the left ventricular wall. The global work waste (GWW) increases, while the global work efficiency (GWE) decreases. There is a significant negative correlation between the PVC burden and GWE (r = -0.70, p <0.01), and a significant positive correlation between the PVC burden and GWW (r = 0.58, p <0.01). GWE is a sensitive indicator for predicting the recurrence of PVCs after radiofrequency ablation. Patients with GWE <91.5%, global longitudinal strain (GLS) <15.5%, and ejection fraction (EF) <62.5% have a higher postoperative recurrence rate. CONCLUSION: PVCs can cause impairment of left ventricular systolic function. GWE is the most sensitive indicator for predicting postoperative recurrence in patients with PVCs. Patients with GWE <91.5%, GLS <15.5%, and EF <62.5% have a higher postoperative recurrence rate.
ABSTRACT
Background: The European Foundation for the Care of Newborn Infants (EFCNI) has promoted the importance of parental involvement in the care of children. Objective: The study aimed to examine how the time required by parents to achieve autonomy in the care of their very low-birth weight newborn infants was modified during the implementation of a training program. Methods: This was an observational prospective study in the context of a quality improvement initiative. The Cuídame (meaning "Take Care of Me" in English) program was aimed at achieving parental autonomy. It was implemented over 2 periods: period 1, from September 1, 2020, to June 15, 2021; and period 2, from July 15, 2021, to May 31, 2022. The days required by parents to achieve autonomy in several areas of care were collected from the electronic health system. Results: A total of 54 and 43 families with newborn infants were recruited in periods 1 and 2, respectively. Less time was required to acheive autonomy in period 2 for participation in clinical rounds (median 10.5, IQR 5-20 vs 7, IQR 4-10.5 d; P<.001), feeding (median 53.5, IQR 34-68 vs 44.5, IQR 37-62 d; P=.049), and observation of neurobehavior (median 18, IQR 9-33 vs 11, IQR 7-16 d; P=.049). More time was required to achieve autonomy for kangaroo mother care (median 14, IQR 7-23 vs 21, IQR 10-31 d; P=.02), diaper change (median 9.5, IQR 4-20 vs 14.5, IQR 9-32 d; P=.04), and infection prevention (median 1, IQR 1-2 vs 6, IQR 3-12; P<.001). Conclusions: Parents required less time to achieve autonomy for participation in clinical rounds, feeding, and observation of neurobehavior during the implementation of the training program. Nevertheless, they required more time to achieve autonomy for kangaroo mother care, diaper change, and infection prevention.
ABSTRACT
BACKGROUND: This meta-analysis aims to evaluate the potential link between common variations in the Surfactant Protein-B (SFTPB) gene and the risk of bronchopulmonary dysplasia (BPD) in preterm neonates. METHODS: All pertinent articles published prior to February 1, 2024, in PubMed, Web of Science, EMBASE, CNKI, and Scopus databases were reviewed. RESULTS: Nineteen case-control studies involving 1149 BPD cases and 1845 non-BPD controls, were analyzed. Combined data indicated a significant link between SFTPB -18 A > C and Intron 4 VNTR polymorphisms with increased BPD susceptibility, while the 1580 C > T polymorphism provides a protective impact on BPD initiation. CONCLUSIONS: Pooled data indicated a significant association between SFTPB -18 A > C and Intron 4 VNTR polymorphisms with increased BPD risk, whereas the 1580 C > T polymorphism confers protection. These findings suggest a genetic susceptibility to BPD, underscoring the complex interplay of different genetic elements in its development.
ABSTRACT
BACKGROUND: AI medical image analysis shows potential applications in research on premature aging and skin. The purpose of this study was to explore the mechanism of the Zuogui pill based on artificial intelligence medical image analysis on ovarian function enhancement and skin elasticity repair in rats with premature aging. MATERIALS AND METHODS: The premature aging rat model was established by using an experimental animal model. Then Zuogui pills were injected into the rats with premature aging, and the images were detected by an optical microscope. Then, through the analysis of artificial intelligence medical images, the image data is analyzed to evaluate the indicators of ovarian function. RESULTS: Through optical microscope image detection, we observed that the Zuogui pill played an active role in repairing ovarian tissue structure and increasing the number of follicles in mice, and Zuogui pill also significantly increased the level of progesterone in the blood of mice. CONCLUSION: Most of the ZGP-induced outcomes are significantly dose-dependent.

BACKGROUND: Short cervical length in the mid-trimester is a powerful predictor of preterm birth. However, clinical significance of cervical length in the third trimester for predicting preterm birth has not been established yet. OBJECTIVE: To examine the predictive role of a shortened cervix in the third trimester for preterm birth in women who had a normal cervical length in the second trimester STUDY DESIGN: : This retrospective cohort study included women who underwent cervical length measured at least once in both the second trimester (16+0 weeks to 27+6weeks) and the early third trimester (28+0 weeks to 33+6weeks). Women with short cervical length in the second trimester, those with multiple pregnancies, those who underwent cerclage operation, and those who had iatrogenic preterm birth were excluded. The study population were divided into two groups based on cervical length in the third trimester: a short cervix (≤ 25 mm) group and a control group (> 25 mm). Rates of preterm birth (< 37 weeks) were compared between two groups. Predictive performances of cervical length in the third trimester for preterm birth were assessed. RESULTS: Women with a short cervical length at 28+0 to 33+6 weeks accounted for 12.6% (nâ¯=â¯717) of the total study population (nâ¯=â¯5,682). Preterm birth rate was 9.5% in the short cervix group, which was significantly higher than that (3.2%) in the control group (p < 0.001). The adjusted odds ratio for short cervical length on preterm birth was 2.73 (95% CI: 1.96-3.79). A short cervix in the third trimester had a sensitivity of 30.1%, a specificity of 88.1%, a positive predictive value of 9.5%, and a negative predictive value of 96.8% in predicting preterm birth. The addition of third-trimester cervical length to the predictive model significantly increased the area under the curve from 0.64 (95% CI: 0.60-0.68) to 0.67 (95% CI: 0.63-0.71) (pâ¯=â¯0.002), demonstrating improved predictive performance. CONCLUSIONS: Approximately 13% of women with normal cervical length in the mid-trimester had a short cervical length after 28 weeks, which increased the risk of preterm birth. The high specificity and negative predictive value of third-trimester cervical length measurements underscore their critical utility in identifying women at low risk for preterm delivery.
ABSTRACT
Premature ovarian failure (POF)is defined as the loss of normal ovarian function before the age of 40 and is characterized by increased gonadotropin levels and decreased estradiol levels and ovarian reserve, often leading to infertility. The incomplete understanding of the pathogenesis of POF is a major impediment to the development of effective treatments for this disease, so the use of animal models is a promising option for investigating and identifying the molecular mechanisms involved in POF patients and developing therapeutic agents. As mice and rats are the most commonly used models in animal research, this review article considers studies that used murine POF models. In this review based on the most recent studies, first, we introduce 10 different methods for inducing murine POF models, then we demonstrate the advantages and disadvantages of each one, and finally, we suggest the most practical method for inducing a POF model in these animals. This may help researchers find the method of creating a POF model that is most appropriate for their type of study and suits the purpose of their research.
ABSTRACT
OBJECTIVES: The aim of this work is to initiate or revive a scientific discussion on the impact of professional life on the parameters of human lifespan. MATERIAL AND METHODS: Presented analysis is based on 8578 Polish elite or well-known person who died in 2001-2021. RESULTS: The results of the conducted analysis indicate that in the case of men the highest values of the median age at death were characteristic of freelancers (median [Me] ± quartile deviation [QD] 85.5±8.5 years), followed by scientists and academic teachers of the biological and medical specialty (Me±QD 84.0±7.5 years) and officers of power structures (Me±QD 83.5±8.5 years). Subsequently, the highest value of the median age at death was recorded for social activists (Me±QD 83.0±9.5 years), clergy (Me±QD 82.0±7.5 years) and scientists and academic teachers of specialties other than biological and medical (Me±QD 82.0±8.0 years). Significantly, at the very end of this list are athletes (Me±QD 77.0±9.0 years). Nevertheless, the results of the analysis confirm that professional athletes are characterized by higher median age at death compared to the general population. Analysis made only within athletes group demonstrated that the parameters of lifespan of athletes of endurance disciplines (Me±QD 78.0±8.0 years) are the most favorable compared to athletes of other disciplines, in particular in compare to team sports athletes (Me±QD 75.0±10.0 years) or combat sports athletes (Me±QD 75.0±7.1 years). CONCLUSIONS: What is new and innovative in this paper is comparing the lifespan characteristics of athletes in comparison to widely represented group of other professions with higher socio-economic status. Unexpectedly, the lifespan of athletes occurred to be lower than for fast all other analyzed occupational groups, except mainly of entertainment musicians. Finally, the results presented in this paper emphasize the need to analyze the lifespan characteristics of athletes in a broader scope than only in relation to the general population.

ABSTRACT
BACKGROUND: Due to the lack of oestrogen, premature ovarian insufficiency (POI) is an independent risk factor for ischaemic heart disease and overall cardiovascular disease. This study aimed to apply layer-specific myocardial strain for early quantitative evaluation of subclinical left ventricular myocardial systolic function changes in patients with POI. METHODS: Forty-eight newly diagnosed, untreated patients with POI (POI group) and fifty healthy female subjects matched for age, height and weight (control group) were enrolled. Standard transthoracic echocardiography was used to measure conventional parameters and layer-specific strain parameters.The layer-specific strain parameters included subendomyocardial global longitudinal strain (GLSendo), mid-layer myocardial global longitudinal strain (GLSmid), subepimyocardial global longitudinal strain (GLSepi), subendomyocardial global circumferential strain (GCSendo), mid-layer myocardial global circumferential strain (GCSmid), and subepimyocardial global circumferential strain (GCSepi). RESULTS: There were no significant differences in age, body mass index (BMI), blood pressure, or left ventricular ejection fraction (LVEF) between the two groups. The end-diastolic interventricular septal thickness (IVST) was greater in the POI group (8.29 ± 1.32 vs. 7.66 ± 0.82, P = 0.008), and the POI group had lower E, E/A, and lateral e' (all P < 0.05). As for systolic functions,the POI group had lower GLSendo, GLSmid, GLSepi, GCSendo, GCSmid, and GCSepi (all P < 0.05).The intraobserver and interobserver coefficients of GLSendo, GLSmid, GLSepi, GCSendo, GCSmid, and GCSepi were greater than 0.900. CONCLUSIONS: POI patients with normal LVEF may suffer from subclinical left ventricular myocardial systolic dysfunction. Echocardiography of layer-specific myocardial strain could more sensitively detect subclinical impairment of left ventricular systolic function in POI patients.
ABSTRACT
INTRODUCTION: The use of hyaluronic acid as a nonsurgical treatment for various conditions within urology has been of great interest in recent literature. OBJECTIVES: In this study, we aimed to provide an updated review and analysis of the current state of hyaluronic acid use in urology, characterize its adverse effects, and briefly discuss future directions of research for hyaluronic acid in urology. METHODS: PubMed searches were run utilizing multiple terms, including "hyaluronic acid," "penile," "augmentation," "Peyronie disease," "premature ejaculation," and "cosmetic urology," among other related iterations. Relevant data extracted included International Index of Erectile Function score, intravaginal ejaculatory latency, glans circumference, penile girth, and plaque size. We also included studies which reported on complications of hyaluronic acid injections. Aggregated analysis was performed on studies with complete pre and post injection data at time closest to 6 months postinjection. RESULTS: A total of 33 studies met our inclusion criteria. Studies had marked heterogeneity in design, but most reported positive results. A total of 16 studies were included in our analysis. Intravaginal ejaculatory latency, penile girth, glans circumference, and International Index of Erectile Function were all increased on a fixed-effects model. Reduction in plaque size was not significant (P = .069). Complications were rare. CONCLUSION: Literature on hyaluronic acid for urologic issues demonstrates promising results; however, the quality of studies was variable. Our analysis of these studies largely corroborates these findings; however, the results are limited by the data available. Hyaluronic acid may be promising, but we highly implore standardization of study regimens in randomized controlled trials.
ABSTRACT
Objective: This study aimed to identify the prevalence of psychiatric disorders in 2 population-based cohorts of children born extremely preterm (EP) 11 years apart to ascertain whether psychiatric outcomes have changed over time following improved survival of EP children. Method: In the EPICure2 study, 200 children born EP (22-26 weeks' gestation) in England in 2006 were assessed at 11 years of age alongside 143 term-born children. Children were assessed using the Developmental and Wellbeing Assessment (DAWBA). DSM-IV diagnoses were assigned by clinical psychiatrists for 145 EP and 98 term-born children. Outcomes were compared between a subsample of children from the EPICure2 cohort (2006, n = 76) and the earlier-born EPICure (1995, n = 161) cohort born at 22 to 25 weeks' gestation in England. Results: EP children in EPICure2 were significantly more likely than term-born children to have any psychiatric disorder (39.3% vs 3.1%; adjusted odds ratio [OR] = 15.1, 95% CI = 4.4-51.1), emotional disorders (14.6% vs 2.0%; OR = 7.3, 95% CI = 1.6-32.7), conduct disorders (6.3% vs 0.0%, p = .01), attention-deficit/hyperactivity disorder (ADHD, 21.9% vs 2.6%; OR = 7.2; 95% CI = 1.5-33.6), and autism spectrum disorder (ASD, 18.9%; vs 0.0%, p < .001). There was no significant difference in the rates of any psychiatric disorder between EP children in the EPICure2 and EPICure cohorts. Conclusion: EP children remain at increased risk for psychiatric disorders at 11 years of age compared with term-born peers. Increased survival has not translated into improved psychiatric outcomes. Health care professionals need to be aware of this ongoing risk when caring for children born preterm.
Medical advances have improved the survival of extremely preterm children, but whether long-term outcomes have also improved is unclear. This study compared rates of psychiatric disorders at age 11 years among 76 children born extremely preterm in 1995 and 161 children born extremely preterm in 2006, to identify trends in psychiatric outcomes. Results showed that children born extremely preterm in 2006 were more likely than term children to have psychiatric disorders (39.3% vs 3.1%). There was no difference in rates of disorders between children born extremely preterm in 2006 and 1995. These results suggest that there has been no improvement in psychological outcomes for extremely preterm children, and healthcare professionals should continue to monitor for psychiatric disorders in this population.
ABSTRACT
When infants cannot directly breastfeed after birth, mothers are advised to initiate lactation through mechanical expression. Families are recommended to target an expression volume of at least 500-750 mL by Day 14 after birth, as this is considered a 'critical window' to establish milk supply. This is challenging for many mothers after a very preterm birth. This article explores the relationship of early milk quantity and later full breastmilk feeding as a 'gold standard' outcome, using statistical techniques designed for diagnostic tests. A cohort of 132 mothers of infants born at 23 + 0 to 31 + 6 weeks' gestational age submitted expressing logs on Day 4, 14 and 21 after birth and provided later feeding outcome. Using receiver operating characteristic (ROC) analysis, the following 24-h milk quantities were identified as associated with high probability of full breastmilk at 36 weeks' post-menstrual age (PMA): on Day 4, ≥250 g (specificity 88%; positive predictive value 88%) and on Day 21 ≥650 g (specificity 88%; positive predictive value 91%). The following values were identified as associated with low probability of full breastmilk at 36 weeks' PMA: on Day 4 <50 g (sensitivity 92%; negative predictive value 72%) and on Day 21 <250 g (sensitivity 90%; negative predictive value 70%). Participants exceeding the high thresholds had 3-4 times increased likelihood of full breastmilk, whereas those below the low thresholds had 3-5 times lower likelihood. These thresholds have potential as targets for families, to provide individualised prognostic information and to help clinicians target more intensive lactation support.
ABSTRACT
Background: Second trimester miscarriage and preterm birth is a significant global problem. Surgical cervical cerclage is performed to prevent pregnancy loss and preterm birth. It utilises either a monofilament or braided suture. It is hypothesised that a braided material becomes colonised with pathogenic bacteria that causes vaginal dysbiosis, infection and cerclage failure. Objectives: The primary objective of the study was to examine the effectiveness of using a monofilament suture material as opposed to a braided suture material on pregnancy loss in women requiring a vaginal cervical cerclage. Design: Superiority open randomised controlled trial. Setting: Seventy-five maternity sites across the UK. Participants: Women experiencing a singleton pregnancy requiring a cervical cerclage. Interventions: Monofilament suture or braided suture. Main outcome measures: The primary outcome was pregnancy loss (miscarriage and perinatal mortality, including any stillbirth or neonatal death in the first week of life). Secondary outcomes included the core outcome set for preterm birth. Methods: Women were randomised on a 1 : 1 basis to monofilament or braided cerclage utilising a bespoke randomisation service with minimisation dependent on the site, indication for cerclage, intention to use progesterone and planned surgical technique. The inclusion criteria were three or more previous mid-trimester losses or preterm births, insertion of a cerclage in a previous pregnancy, a history of a mid-trimester loss or preterm birth with a shortened cervical length in the current pregnancy or in women who clinicians deemed at risk of preterm birth. The exclusion criteria were an emergency or rescue cerclage, age of < 18 years, being unable to give informed consent or the cerclage having to be placed abdominally. The original sample size was calculated based on a relative risk reduction of 41% from a pregnancy loss rate of 19% in the braided group to 11% in the monofilament group with 90% power and alpha at p = 0.05. The independent data monitoring committee noted a lower-than-anticipated pooled event rate within the trial and recommended an increase in sample size to 2050. The outcome data were collected using clinical record forms from the maternal and neonatal medical records and reported to Birmingham Clinical Trials Unit. Results: A total of 2049 women were randomised, after withdrawals and loss to follow-up, data on 1005 women in the monofilament group and 993 women in the braided group were included. The baseline demographics between the groups were similar. There was no evidence of a difference in pregnancy loss rates between the monofilament and braided groups (80/1003 vs. 75/993; adjusted risk ratio: 1.05, 95% confidence interval: 0.79 to 1.40; adjusted risk difference: 0.002, 95% confidence interval: -0.02 to 0.03). Limitations: The trial did not collect long-term paediatric outcomes. There were no safety concerns. Conclusions: There was no evidence of a difference in pregnancy loss between a monofilament suture and a braided suture. Future work: Long-term follow-up of neonates born within the C-STICH (cerclage suture type for an insufficient cervix and its effects on health outcomes) trial.

Cervical cerclage is an operation performed in pregnancy to prevent miscarriage and preterm birth. A cervical cerclage is sometimes recommended in women who have had babies born prematurely before or who have had previous cervical surgery. A cerclage operation involves a stitch being inserted around the neck of the womb (cervix) to keep it closed during pregnancy and to prevent it opening prematurely. When performing the operation, the doctor can use different types of threads made of different materials. The threads used to perform the operation are called sutures. One suture type is a single strand or monofilament thread, and the other is a multifilament braided thread with lots of thin strands woven together. Some evidence has suggested that using a monofilament suture thread prevented pregnancy loss by preventing infection. Therefore, we performed a randomised controlled trial of the use of monofilament suture thread versus braided suture thread, aiming to reduce pregnancy loss in women who were having a cerclage as part of their routine care. The women consented to take part in the study and were randomly allocated to their cerclage performed with either a monofilament or braided suture thread; there was no other change to their planned pregnancy care. What happened in their pregnancy was recorded from their medical records and analysed. A total of 2049 women agreed to take part in the study and consented to the analysis of their pregnancy and neonatal outcomes. Cerclage suture type for an insufficient cervix and its effects on health outcomes showed that there was no difference in pregnancy loss between the two suture threads. There was decreased maternal sepsis and decreased chorioamnionitis (which is an infection inside the womb during labour) in the women who received a monofilament suture, which needs further investigation. Although more women who had a cerclage using the monofilament thread needed a small operation and an anaesthetic, often between 36 and 37 weeks, to remove the monofilament suture prior to a vaginal birth, there were no differences in the outcomes for their babies.

Introduction: Moderate-to-late preterm infants constitute the majority within the preterm infant population. Most research on preterm infants has focused on very preterm children, often treating moderate-to-late preterm infants as similar to full-term infants. Our objective was to compare clinical, respiratory, cardio-metabolic and neurodevelopmental outcomes in adolescents aged 12-15 years born moderate and late preterm with a control group of the same age born full-term. Methods: Observational cross-sectional study, comparing moderate-to-late preterm (32-36+6 weeks' gestational age) with full-term adolescents (37-41+6 weeks' gestational age; 75 each group). Perinatal and neonatal history were collected as well as data on respiratory evolution (ISAAC questionnaire for asthma symptoms for adolescents 13-14 years), anthropometric values, learning difficulties, behavioral test (screening questionnaire for high-performance autism spectrum disorder and evaluation test for attention deficit hyperactivity disorder), skin prick test, pulmonary function test, echocardiogram and blood pressure. A blood test with metabolic profile was conducted. Results: Moderate-to-late preterm adolescents had more current asthma [p = 0.008, OR3 (95% CI 1.26-7.14)] and longer duration of combined treatments to control asthma (inhaled corticosteroids and anti-leukotrienes; p = 0.048). Forced vital capacity <80% was detected more often in moderate-to-late preterm patients (p = 0.013). When assessing right ventricle, moderate-to-late preterm adolescents showed better tricuspid annular plane systolic excursion z-score (p = 0.003), shortening fraction (p < 0.001) and E/A ratio z-score (p = 0.002). Regarding left ventricular assessment, moderate-to-late preterm group had smaller ventricle diastolic diameter (p = 0.04) and lower posterior wall z-score values (p = 0.037). They also showed a better S'wave z-score (p = 0.027), E wave (p = 0.005), E/A ratio (p = 0.003) and a higher septal myocardial performance index z-score (p = 0.025). Moderate-to-late preterm adolescents presented lower weight z-score (p = 0.039), body mass index z-score (p = 0.013), Waterlow weight index (p = 0.006) and higher undernutrition index [p = 0.04; OR 1.4 (95% CI 1-1.9)]. Although there were no differences in neurodevelopmental survey or behavioral tests. Conclusion: Our findings underscore the importance of extended follow-up for this predominant group of premature infants to identify potential respiratory, cardiac and anthropometric issues that may emerge in the future.
ABSTRACT
Background: Data regarding risk factors for premature coronary artery disease (PCAD) is scarce given that few research focus on it. This study aimed to develop and validate a clinical nomogram for PCAD patients in Guangzhou. Methods: We recruited 108 PCAD patients (female ≤65 years old and male ≤55 years old) and 96 healthy controls from Sun Yat-sen Memorial Hospital of Sun Yat-sen University between 01/01/2021 and 31/12/2022. Twenty potentially relevant indicators of PCAD were extracted. Next, the least absolute shrinkage and selection operator (LASSO) regression analysis was used to optimize variable selection. The nomogram was developed based on the selected variables visually. Results: Independent risk factors, including body mass index (BMI), history of PCAD, glucose, Apolipoprotein A1(ApoA1), high density lipoprotein 2-cholesterol (HDL2-C), total cholesterol and triglyceride, were identified by LASSO and logistic regression analysis. The nomogram showed accurate discrimination (area under the receiver operator characteristic curve, ROC, 87.45 %, 95 % CI: 82.58 %-92.32 %). Decision curve analysis (DCA) suggested that the nomogram was clinical beneficial. HDL2, one risk factor, was isolated by a two-step discontinuous density-gradient ultracentrifugation method. And HDL2 from PCAD patients exhibited less 3H-cholesterol efflux (22.17 % vs 26.64 %, P < 0.05) and less delivery of NBD-cholesterol detecting by confocal microscope compared with healthy controls. Conclusions: In conclusion, the seven-factor nomogram can achieve a reasonable relationship with PCAD, and a large cohort were needed to enhance the credibility and effectiveness of our model in future.
