Background
Antenatal corticosteroids for women at risk of preterm birth reduce neonatal morbidity and mortality, but there is limited evidence regarding their effects on long-term health. This study assessed cardiovascular outcomes at 50 years after antenatal exposure to corticosteroids.

Methods and findings
We assessed the adult offspring of women who participated in the first randomised, double-blind, placebo-controlled trial of antenatal betamethasone for the prevention of neonatal respiratory distress syndrome (RDS) (1969 to 1974). The first 717 mothers received 2 intramuscular injections of 12 mg betamethasone or placebo 24 h apart and the subsequent 398 received 2 injections of 24 mg betamethasone or equivalent volume of placebo. Follow-up included a health questionnaire and consent to access administrative data sources. The co-primary outcomes were the prevalence of cardiovascular risk factors (any of hypertension, hyperlipidaemia, diabetes mellitus, gestational diabetes mellitus, or prediabetes) and age at first major adverse cardiovascular event (MACE) (cardiovascular death, myocardial infarction, coronary revascularisation, stroke, admission for peripheral vascular disease, and admission for heart failure). Analyses were adjusted for gestational age at entry, sex, and clustering. Of 1,218 infants born to 1,115 mothers, we followed up 424 (46% of survivors; 212 [50%] female) at mean (standard deviation) age 49.3 (1.0) years. There were no differences between those exposed to betamethasone or placebo for cardiovascular risk factors (159/229 [69.4%] versus 131/195 [67.2%]; adjusted relative risk 1.02, 95% confidence interval [CI] [0.89, 1.18;]; p = 0.735) or age at first MACE (adjusted hazard ratio 0.58, 95% CI [0.23, 1.49]; p = 0.261). There were also no differences in the components of these composite outcomes or in any of the other secondary outcomes. Key limitations were follow-up rate and lack of in-person assessments.

Conclusions
There is no evidence that antenatal corticosteroids increase the prevalence of cardiovascular risk factors or incidence of cardiovascular events up to 50 years of age. Established benefits of antenatal corticosteroids are not outweighed by an increase in adult cardiovascular disease.
Comparison of psychological interventions for anxiety, depression, fatigue and quality of life in colorectal cancer survivors: A systematic review and network meta-analysis protocol
Authors: Liang Yujie , Zhang Xu , Li Shan , Wang Zhiwen 
Published: April 2024

Background
Previous studies have found that psychological interventions have a positive effect on improving physical and psychological problems in colorectal cancer survivors. However, there is still a lack of high-quality evidence reviews that summarize and compare the impact of different psychological interventions. The aim of this study was to synthesize existing psychological interventions and use network meta-analysis to explore whether psychological interventions improve anxiety, depression, fatigue and quality of life in colorectal cancer (CRC) survivors.

Methods
We will extract relevant randomized controlled trials of psychological interventions for CRC survivors from eight electronic databases, including PubMed, Embase, The Cochrane Library, Web of Science, CINAHL, PsycInFO, CNKI, and Wanfang database. Two reviewers will independently screen the literature and extract data. The risk of bias of the included studies will be assessed using the RoB2: Revised Cochrane Risk of Bias Tool. We will then conduct paired meta-analyses and network meta-analyses of the extracted data, using a frequency-based framework and random effects models.

Discussion
To the best of our knowledge, this study is the first proposed qualitative and quantitative integration of existing evidence using systematic evaluation and network meta-analysis. This study will inform health policy makers, healthcare providers’ clinical intervention choices and guideline revisions, and will help to reduce depression and anxiety in CRC survivors, reduce fatigue, improve quality of life.

Published: April 2024

Purpose
The cryopreservation process damages oocytes and impairs development potential. As a potent antioxidant, C-phycocyanin (PC) regulates reproductive performance. However, its beneficial effects on vitrified human oocytes remain unknown.

Methods
In this study, human GV-stage oocytes obtained from controlled ovarian hyperstimulation (COH) cycles were randomly allocated to three groups: fresh oocyte without freezing (F group), vitrification in medium supplemented with PC (P group), and vitrification in medium without PC as control group (C group). After warming, viable oocytes underwent in vitro maturation.

Results
Our results showed that 3 μg/mL PC treatment increased the oocyte maturation rate after cryopreservation. We also found that PC treatment maintains the regular morphological features of oocytes. After PC treatment, confocal fluorescence staining showed a significant increase in the mitochondrial membrane potential of the vitrified oocytes, along with a notable decrease in intracellular reactive oxygen species and the early apoptosis rate. Finally, after in vitro maturation and parthenogenetic activation, vitrified oocytes had a higher potential for cleavage and blastocyst formation after PC treatment.

Conclusion
Our results suggest that PC improves the developmental potential of cryopreserved human GV-stage oocytes by attenuating oxidative stress and early apoptosis and increasing the mitochondrial membrane potential.

BackgroundInternally displaced people (IDPs), uprooted by conflict, violence, or disaster, struggle with the trauma of violence, loss, and displacement, making them significantly more vulnerable to post-traumatic stress disorder (PTSD). Therefore, we conducted a systematic review and meta-analysis to assess the prevalence and associated factors of PTSD among IDPs in Africa.MethodsA comprehensive search of electronic databases was conducted to identify relevant studies published between 2008 and 2023. The search included electronic databases such as PubMed, CABI, EMBASE, SCOPUS, CINHAL, and AJOL, as well as other search sources. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Data were extracted using Microsoft Excel, and analysis was performed using STATA 17 software. The quality of the included studies was assessed using the JBI quality appraisal tool. A random-effects model was used to estimate the pooled prevalence of PTSD and its associated factors. The funnel plot and Egger’s regression test were used to assess publication bias, and I2test statistics was used to assess heterogeneity. The protocol for this review has been registered with PROSPERO (ID: CRD42023428027).ResultsA total of 14 studies with a total of 7,590 participants met the inclusion criteria. The pooled prevalence of PTSD among IDPs in Africa was 51% (95% CI: 38.-64). Female gender (OR = 1.99, 95% CI: 1.65–2.32), no longer married (OR = 1.93, 95% CI: 1.43–2.43), unemployment (OR = 1.92, 95% CI: 1.17–2.67), being injured (OR = 1.94, 95% CI: 1.50–1.50), number of traumatic events experienced [4-7(OR = 2.09, 95% CI: 1.16–3.01), 8–11 (OR = 2.09, 95% CI: 2.18–4.12), 12–16 (OR = 5.37, 95% CI: 2.61–8.12)], illness without medical care (OR = 1.92, 95% CI: 1.41–2.29), being depressed (OR = 2.97, 95% CI: 2.07–3.86), and frequency of displacement more than once (OR = 2.13, 95% CI: 1.41–2.85) were significantly associated with an increased risk of PTSD.ConclusionsThe findings of this systematic review and meta-analysis highlight the alarming prevalence of PTSD among IDPs in Africa. Female gender, marital status, number of traumatic events, ill health without medical care, depression, and frequency of displacement were identified as significant risk factors for PTSD. Effective interventions and the development of tailored mental health programs are needed to prevent PTSD among IDPs, focusing on the identified risk factors.
Whole transcriptome sequencing analyses of islets reveal ncRNA regulatory networks underlying impaired insulin secretion and increased β-cell mass in high fat diet-induced diabetes mellitus
Authors: Ma Jinfang , Gao Rui , Xie Qingxing , Pan Xiaohui , Tong Nanwei 
Published: April 2024

Aim
Our study aims to identify novel non-coding RNA-mRNA regulatory networks associated with β-cell dysfunction and compensatory responses in obesity-related diabetes.

Methods
Glucose metabolism, islet architecture and secretion, and insulin sensitivity were characterized in C57BL/6J mice fed on a 60% high-fat diet (HFD) or control for 24 weeks. Islets were isolated for whole transcriptome sequencing to identify differentially expressed (DE) mRNAs, miRNAs, IncRNAs, and circRNAs. Regulatory networks involving miRNA–mRNA, lncRNA–mRNA, and lncRNA–miRNA–mRNA were constructed and functions were assessed through Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses.

Results
Despite compensatory hyperinsulinemia and a significant increase in β-cell mass with a slow rate of proliferation, HFD mice exhibited impaired glucose tolerance. In isolated islets, insulin secretion in response to glucose and palmitic acid deteriorated after 24 weeks of HFD. Whole transcriptomic sequencing identified a total of 1324 DE mRNAs, 14 DE miRNAs, 179 DE lncRNAs, and 680 DE circRNAs. Our transcriptomic dataset unveiled several core regulatory axes involved in the impaired insulin secretion in HFD mice, such as miR-6948-5p/Cacna1c, miR-6964-3p/Cacna1b, miR-3572-5p/Hk2, miR-3572-5p/Cckar and miR-677-5p/Camk2d. Additionally, proliferative and apoptotic targets, including miR-216a-3p/FKBP5, miR-670-3p/Foxo3, miR-677-5p/RIPK1, miR-802-3p/Smad2 and ENSMUST00000176781/Caspase9 possibly contribute to the increased β-cell mass in HFD islets. Furthermore, competing endogenous RNAs (ceRNA) regulatory network involving 7 DE miRNAs, 15 DE lncRNAs and 38 DE mRNAs might also participate in the development of HFD-induced diabetes.

Conclusions
The comprehensive whole transcriptomic sequencing revealed novel non-coding RNA-mRNA regulatory networks associated with impaired insulin secretion and increased β-cell mass in obesity-related diabetes.
Association of per- and polyfluoroalkyl substances with constipation: The National Health and Nutrition Examination Survey (2005–2010)
Authors: Zhao Yifan , Pu Ke , Zheng Ya , Wang Yuping , Wang Jun , Zhou Yongning 
Published: April 2024

Background
The impact of per- and polyfluoroalkyl substances (PFAS) on constipation, as mediated through gastrointestinal absorption and perturbations to the intestinal microecology, remains poorly understood.

Objective
This study seeks to explain the relationship between PFAS and constipation.

Methods
A total of 2945 adults from the National Health and Nutrition Examination Survey (NHANES) 2005–2010 were included in this study. Constipation was defined using the Bristol Stool Form Scale (BSFS) based on stool consistency. The relationship between PFAS and constipation was evaluated using weighted logistic regression and restricted cubic spline (RCS) analysis, while adjusting for confounding variables.

Results
The weighted median concentration of total PFAS (ΣPFAS) was significantly lower in individuals with constipation (19.01 μg/L) compared to those without constipation (23.30 μg/L) (p < 0.0001). Subgroup analysis revealed that the cumulative effect of PFAS was more pronounced in the elderly, men, individuals with obesity, high school education or equivalent, and high-income individuals (p < 0.05). After adjusting for confounding factors, multivariable analysis demonstrated an inverse association between PFOA [OR (95% CI), 0.666(0.486,0.914)] and PFHxS [OR (95% CI), 0.699(0.482,1.015)], and constipation. None of the personal and lifestyle factors showed a significant correlation with this negative association, as confirmed by subgroup analysis and interaction testing (p for interaction > 0.05). The RCS analysis demonstrated a linear inverse relationship between PFAS levels and constipation.

Conclusion
The findings of this study provide evidence of a significant inverse correlation between serum concentrations of PFAS, particularly PFOA and PFHxS, and constipation.
Advance care planning as perceived by marginalized populations: Willing to engage and facing obstacles
Authors: Izumi Shigeko (Seiko) , Garcia Ellen , Kualaau Andrew , Sloan Danetta E. , DeSanto-Madeya Susan , Candrian Carey , Anderson Elizabeth , Sanders Justin 
Published: April 2024

Background
Health disparities exist in end-of-life (EOL) care. Individuals and communities that are marginalized due to their race, ethnicity, income, geographic location, language, or cultural background experience systemic barriers to access and receive lower quality EOL care. Advance care planning (ACP) prepares patients and their caregivers for EOL decision-making for the purpose of promoting high-quality EOL care. Low engagement in ACP among marginalized populations is thought to have contributed to disparity in EOL care. To advance health equity and deliver care that aligns with the goals and values of each individual, there is a need to improve ACP for marginalized populations.

Aim
To describe how patients from marginalized populations experience and perceive ACP.

Methods
We used an interpretive phenomenological approach with semi-structured qualitative interviews. Participants were recruited from four primary care clinics and one nursing home in a US Pacific Northwest city. Thirty patients from marginalized populations with serious illness participated in individual interviews between January and December 2021. Participants were asked to describe their experiences and perceptions about ACP during the interviews.

Results
The mean age of 30 participants was 69.5; 19 (63%) were women; 12 (40%) identified as Asian/Pacific Islanders, 10 (33%) as Black; and 9 (30%) were non-native English speakers. Our three key findings were: 1) patients from marginalized populations are willing to engage in ACP; 2) there were multiple obstacles to engaging in ACP; and 3) meaningful ACP conversations could happen when clinicians listen. Although participants from marginalized populations were willing to engage in ACP, a fragmented and restrictive healthcare system and clinicians’ biased behaviors or lack of interest in knowing their patients were obstacles. Participants who felt their clinicians took time and listened were encouraged to engage in ACP.

Conclusion
Patients from marginalized populations are willing to engage in ACP conversations despite a common belief otherwise. However, obstacles to meaningful ACP conversations with healthcare providers exist. Clinicians need to be aware of these obstacles and listen to build trust and engage marginalized patients in mutually meaningful ACP conversations.
Validation of the Italian version of a patient-reported outcome measure for Hereditary Spastic Paraplegia
Authors: Diella Eleonora , D’Angelo Maria Grazia , Stefan Cristina , Girardi Giulia , Morganti Roberta , Martinuzzi Andrea , Biffi Emilia 
Published: April 2024

Background and aim
Patient-reported outcome measures (PROMs) are recognized as valuable measures in the clinical setting. In 2018 we developed the Italian version of the “Hereditary Spastic Paraplegia-Self Notion and Perception Questionnaire” (HSP-SNAP), a disease-specific questionnaire that collects personal perception on motor symptoms related to HSP such as stiffness, weakness, imbalance, reduced endurance, fatigue and pain. In this study our primary aim was to assess the questionnaire validity and reliability. Our secondary aim was to characterize the symptoms “perceived” by patients with HSP and compare them with those “perceived” by age-matched healthy subjects.

Methods
The 12-item HSP-SNAP questionnaire was submitted to 20 external judges for comprehensibility and to 15 external judges for content validity assessment. We recruited 40 subjects with HSP and asked them to fill the questionnaire twice for test-retest procedure. They also completed the Medical Outcome Survey Short Form (SF-36) and were evaluated by the Spastic Paraplegia Rating Scale and the Six-Minute Walk Test. We also recruited 44 healthy subjects who completed the HSP-SNAP once to test score variability.

Results
The HSP-SNAP content validity index was high (0.8±0.1) and the test-retest analysis showed high reliability (ICC = 0.94). The mean HSP-SNAP score (score range 0–48) of the HSP group was 22.2±7.8, which was significantly lower than healthy subjects (43.1±6.3). The most commonly perceived symptom was stiffness, followed by weakness and imbalance.

Conclusion
Although HSP-SNAP does not investigate non-motor symptoms and we validated only its Italian version, it showed good validity and reliability and it could be used in combination with other objective outcome measures for clinical purposes or as endpoints for future clinical rehabilitation studies.

Progesterone-Only Contraceptive-Induced Ischemic Colitis
Authors: Rajamanuri Medha , Garg Meher , Siddiqui Harris , Pannala Sreeram 
Published: April 2024

ABSTRACT
Ischemic colitis (IC) occurs when there is a temporary lack of adequate blood supply to the intestines, particularly in vulnerable areas such as the splenic flexure and sigmoid colon, which lack sufficient collateral blood vessels. Although primarily seen in older individuals with atherosclerotic risk factors, IC can also be triggered by hormonal contraceptives in young women. Although estrogen-containing oral contraceptives are known to increase thromboembolic risk, the impact of progesterone is not well understood. We report a unique case of biopsy-confirmed IC in a previously healthy 30-year-old woman who presented with abdominal pain and bloody diarrhea 2 months after initiation of progesterone-only oral contraceptive. This occurrence, although rare, underscores the need for further research on the impact of progesterone on coagulation, especially concerning mesenteric arteries.

Published: April 2024

INTRODUCTION:
Tegoprazan (TPZ), a potassium-competitive acid blocker, exerts a strong acid-suppression effect and a rapid onset of action. However, research on TPZ-amoxicillin (TA) dual treatment is limited. Here, we compared the safety and efficacy of TPZ-amoxicillin dual treatment and TPZ, bismuth potassium citrate, amoxicillin, and clarithromycin (TBAC) quadruple therapy in patients newly diagnosed with H. pylori infection over a 14-day treatment period.

METHODS:
A total of 236 patients newly diagnosed with H. pylori were enrolled in this multicenter, prospective, open-label, and randomized controlled study. Patients randomly received either TA dual or TBAC quadruple therapy. The incidence of adverse reactions and treatment compliance were recorded and then analyzed.

RESULTS:
The intention-to-treat analysis revealed that H. pylori eradication rates were 83.9% (95% confidence interval 78.2%–91.3%) and 81.4% (95% confidence interval 74.2%–88.5%) for the TA and TBAC groups, respectively, with no statistically significant difference between them (P = 0.606). The per-protocol analysis revealed that the H. pylori eradication rates were 88.3% and 84.8% for the TA and TBAC groups, respectively (P = 0.447). The incidence of adverse reactions was significantly lower in the TA group than in the TBAC group (4.2% vs 15.3%, P = 0.004). Moreover, the TA group demonstrated substantially higher treatment compliance than the TBAC group (94.1% vs 89.0%, P = 0.020).

DISCUSSION:
The TA dual therapy successfully eradicated H. pylori with a high eradication rate and a low incidence of adverse reactions. Therefore, this treatment is recommended as an alternative course for patients newly diagnosed with H. pylori infection.
Tethered spinal cord syndrome associated with spina bifida: clinical and radiological characteristics and indications for surgery (systematic review of the literature)

Published: April 2024

Objective. To analyze literature data on clinical and radiation characteristics of the tethered spinal cord syndrome in spina bifida and to define criteria for indications for surgical treatment.Material and Methods. A search for prospective cohort clinical studies evaluating the clinical and radiation picture and indications for surgicalcorrection of the tethered spinal cord syndrome associated with spina bifida, published in 2005–2023 was performed in the Pubmed, EMBASE, eLibrary and the Сochrane Library databases. The literature search was carried out by one researcher. The study was carried out in accordance with the international recommendations for writing systematic reviews and meta-analyses PRISMA. The levels of evidencefor reliability and grades of the strength of recommendations were evaluated according to the ASCO Guidelines.Results. A total of 394 literature sources were found in the databases. Duplicate materials (n = 81) have been removed. When non-fulltext articles were excluded, only 28 out of 251 remained studies met the inclusion criteria and were analyzed. According to the level of evidence, 18 of them were classified as B level, and 10 – as C level.Conclusion. The components of the tethered spinal cord syndrome are a dystopic spinal cord cone, a shortened fixed filum terminale, and the presence of a lumbosacral lipoma. At the same time, there are currently no clear criteria for the integral assessment of the clinical and morphofunctional state of patients, and the available scales are not specific. The described MRI criteria are limited by the level of evidence, but despite this, they reflect a high level of consensus among experts, including that on the defining indications for surgical spinal corduntethering. The lack of clear indications for surgical intervention and the debatability of performing preventive untethering of the spinal cord require further study of the problem with an emphasis on analyzing the criteria for tethered spinal cord syndrome.
