Surgical necrotising enterocolitis (NEC) continues to carry significant morbidity and mortality in preterm and very-low-birth-weight infants. This review presents up-to-date evidence to guide the shift from medical to surgical treatment and to improve management during and after surgery. Need for surgery is best anticipated through dynamic clinical assessment, supported by laboratory markers of systemic inflammation or ischemia and targeted imaging, while pneumoperitoneum remains the sole absolute indication for immediate intervention. In infants without perforation, the timing of surgery remains challenging: delayed surgery after clinical deterioration worsens long-term outcomes, whereas very early surgery often reflects severe disease leading to greater bowel loss, highlighting the need for carefully timed intervention after brief stabilisation. Laparotomy remains the cornerstone of surgical management, with peritoneal drainage serving as a temporising option for the most unstable infants and laparoscopy emerging as a feasible adjunct. Long-term complications, including strictures, short bowel syndrome, neurodevelopmental impairment, bronchopulmonary dysplasia and severe retinopathy of prematurity highlight the need for better predictive tools, enhanced imaging of bowel viability, and rigorous nutritional support, while long-term quality-of-life outcomes remain insufficiently studied.

Breast augmentation surgery (BAS) is one of the commonest plastic surgery procedures worldwide. A long-standing debate on the use of anatomical implants versus round implants in terms of complications, especially implant rotation, monopolizes relevant bibliography in recent years. A retrospective cohort study was conducted. All patients' records undergoing primary breast augmentation with anatomical implants from January 2010 to December 2023 by a single surgeon (V.K.), who implemented a novel surgical technique, were assessed for eligibility. Patients' demographics, and preoperative and operative data were recorded. Statistical analysis was conducted using IBM® SPSS® Statistics version 25.0. In total, 622 patients underwent breast augmentation surgery with anatomical implants during the study period (median age 34years, median body mass index 22.3, median follow-up time 43.8months). Ten implants were rotated (0.8%) and correlated in univariate analysis with implant projection type (p=0.003). Twelve implants (0.96%) were complicated by capsular contracture, six (0.48%) by bottoming-out deformity, two patients (0.32%) developed a unilateral hematoma in the first 24h and one patient (0.16%) developed a double-bubble deformity. The use of the proposed surgical technique minimizes complication rates, making anatomical implants an optimal choice for breast augmentation surgery.

This study examines the relationship between obesity, oxidative stress, and reproductive dysfunction. It focuses on the effects of sleeve gastrectomy on gene expression and hormone profiles in 29 women with severe obesity (BMI ≥ 40 kg/m2). Pre- and post-surgical investigations revealed significant differences in major gene expressions and hormonal markers. CART expression reduced significantly from 0.27 ± 4.43 to -3.42 ± 1.14 (p < 0.001), while leptin expression decreased from -1.87 ± 1.75 to -0.13 ± 1.55 (p < 0.001), indicating better metabolic regulation. In contrast, eNOS expression increased considerably from -4.87 ± 1.70 to 1.18 ± 2.31 (p = 0.003), indicating improved endothelial function and nitric oxide bioavailability, which is critical for vascular health and reproduction. Correlation research before surgery indicated no significant relationships between eNOS, CART, or leptin and clinical indicators, implying that these genes function independently in pre-surgical metabolism. While most associations remained negligible after surgery, a significant negative connection between eNOS expression and SHBG levels appeared (r = -0.365, p = 0.049), indicating potential interactions in hormonal regulation pathways following metabolic improvements. These findings emphasize the importance of bariatric surgery in reducing the negative effects of obesity on reproductive health by altering critical cellular pathways. Significant increases in CART, leptin, and eNOS expression indicate reduced oxidative stress, improved vascular tone, and hormonal balance, all of which contribute to increased reproductive capacity. This study sheds light on the molecular processes that link obesity, metabolic health, and fertility, underlining bariatric surgery's therapeutic potential for women experiencing obesity-related infertility.

Objective: To investigate the clinical characteristics associated with the presence of LSV at birth. Design: Prospective 1:1 case–control study. Setting: Two tertiary neonatal units in Athens, Greece. Patients: Premature neonates (≤36 weeks gestational age) who underwent cerebral ultrasound within the first 3 weeks of life, where LSV was detected. Main outcome measure: Associations between LSV and clinical characteristics at birth. Both unmatched and matched analyses stratifying the study population by gestational week were conducted. Two-sided p-values were computed using the likelihood ratio test. Results: This study included 166 participants (83 cases and 83 controls). Neonates with LSV exhibited more concurrent cerebral findings, notably periventricular echogenicity. LSV was correlated with higher z-scores for head circumference and body length. LSV was not associated with congenital CMV. Conclusions: This study indicated a relationship between LSV and increased head circumference and body length. Further research is warranted to explore LSV’s pathophysiological mechanisms.

Despite the proven superiority of various luteal phase support protocols (LPS) over placebo in view of improved pregnancy rates in fresh cycles of IVF (in vitro fertilization) and ICSI (intracytoplasmic sperm injection) cycles, there is ongoing controversy over specific LPS protocol selection, dosage, and duration. The aim of the present study was to identify the optimal LPS under six core aspects of ART success, clinical pregnancy, live birth as primary outcomes and biochemical pregnancy, miscarriage, multiple pregnancy, ovarian hyperstimulation syndrome (OHSS) events as secondary outcomes. Twelve databases, namely Embase (OVID), MEDLINE (R) (OVID), GlobalHealth (Archive), GlobalHealth, Health and Psychosocial Instruments, Maternity & Infant Care Database (MIDIRS), APA PsycTests, ClinicalTrials.gov, HMIC Health Management Information Consortium, CENTRAL, Web of Science, Scopus and two prospective registers, MedRxiv, Research Square were searched from inception to Aug.1st, 2023, (PROSPERO Registration: CRD42022358986). Only Randomised Controlled Trials (RCTs) were included. Bayesian network meta-analysis (NMA) model was employed for outcome analysis, presenting fixed effects, odds ratios (ORs) with 95% credibility intervals (CrIs). Vaginal Progesterone (VP) was considered the reference LPS given its’ clinical relevance. Seventy-six RCTs, comparing 22 interventions, and including 26,536 participants were included in the present NMA. Overall CiNeMa risk of bias was deemed moderate, and network inconsistency per outcome was deemed low (Multiple pregnancy χ2: 0.11, OHSS χ2: 0.26), moderate (Clinical Pregnancy: χ2: 7.02, Live birth χ2: 10.95, Biochemical pregnancy: χ2: 6.60, Miscarriage: χ2: 11.305). Combinatorial regimens, with subcutaneous GnRH-a (SCGnRH-a) on a vaginal progesterone base and oral oestrogen (OE) appeared to overall improve clinical pregnancy events; VP + OE + SCGnRH-a [OR 1.57 (95% CrI 1.11 to 2.22)], VP + SCGnRH-a [OR 1.28 (95% CrI 1.05 to 1.55)] as well as live pregnancy events, VP + OE + SCGnRH-a [OR 8.81 (95% CrI 2.35 to 39.1)], VP + SCGnRH-a [OR 1.76 (95% CrI 1.45 to 2.15)]. Equally, the progesterone free LPS, intramuscular human chorionic gonadotrophin, [OR 9.67 (95% CrI 2.34, 73.2)] was also found to increase live birth events, however was also associated with an increased probability of ovarian hyperstimulation, [OR 1.64 (95% CrI 0.75, 3.71)]. The combination of intramuscular and vaginal progesterone was associated with higher multiple pregnancy events, [OR 7.09 (95% CrI 2.49, 31.)]. Of all LPS protocols, VP + SC GnRH-a was found to significantly reduce miscarriage events, OR 0.54 (95% CrI 0.37 to 0.80). Subgroup analysis according to ovarian stimulation (OS) protocol revealed that the optimal LPS across both long and short OS, taking into account increase in live birth and reduction in miscarriage as well as OHSS events, was VP + SCGnRH-a, with an OR 2.89 [95% CrI 1.08, 2.96] and OR 2.84 [95% CrI 1.35, 6.26] respectively. Overall, NMA data suggest that combinatorial treatments, with the addition of SCGnRH-a on a VP base result in improved clinical pregnancy and live birth events in both GnRH-agonist and antagonist ovarian stimulation protocols.

Abstract Background There is an emerging need to systematically investigate the causes for the increased cesarean section rates in Greece and undertake interventions so as to substantially reduce its rates. To this end, the ability of the participating Greek obstetricians to follow evidence-based guidelines and respond to other educational and behavioral interventions while managing labor will be explored, along with barriers and enablers. Herein discussed is the protocol of a stepped-wedge designed intervention trial in Greek maternity units with the aforementioned goals in mind, named ENGAGE (ENhancinG vAGinal dElivery in Greece). Methods Twenty-two selected maternity units in Greece will participate in a multicenter stepped-wedge randomized prospective trial involving 5,000 to 8,000 births, with two of them entering the intervention period of the study each month (stepped randomization). The maternity care units entering the study will apply the suggested interventions for a period of 8–18 months depending on the time they enter the intervention stage of the study. There will also be an initial phase of the study lasting from 8 to 18 months including observation and recording of the routine practice (cesarean section, vaginal birth, and maternal and perinatal morbidity and mortality) in the participating units. The second phase, the intervention period, will include such interventions as the application of the HSOG (the Hellenic Society of Obstetrics and Gynecology) Guidelines on labor management, training on the correct interpretation of cardiotocography, and dealing with emergencies in vaginal deliveries, while the steering committee members will be available to discuss and implement organizational and behavioral changes, answer questions, clarify relevant issues, and provide practical instructions to the participating healthcare professionals during regular visits or video conferences. Furthermore, during the study, the results will be available for the participating units in order for them to monitor their own performance while also receiving feedback regarding their rates. Τhe final 2-month phase of the study will be devoted to completing follow-up questionnaires with data concerning maternal and neonatal morbidities that occurred after the completion of the intervention period. The total duration of the study is estimated at 28 months. The primary outcome assessed will be the cesarean section rate change and the secondary outcomes will be maternal and neonatal morbidity and mortality. Discussion The study is expected to yield new information on the effects, advantages, possibilities, and challenges of consistent clinical engagement and implementation of behavioral, educational, and organizational interventions described in detail in the protocol on cesarean section practice in Greece. The results may lead to new insights into means of improving the quality of maternal and neonatal care, particularly since this represents a shared effort to reduce the high cesarean section rates in Greece and, moreover, points the way to their reduction in other countries.

Abstract Study question This study aimed to the evaluation of PRP injection in women with ovarian dysfunction (with POR, POI, perimenopause and menopause) to promote the ovarian rejuvenation. Summary answer Intraovarian infusion of autologous PRP exhibited remarkable evidence and promising results to restore ovarian insufficiency. What is known already Ovarian dysfunctions, such as premature ovarian insufficiency (POI) and poor ovarian response (POR) are conditions, characterized by the collapse of ovarian function and are considered currently as a global public health issue. Primary factors that are associated with female infertility include endocrine dysfunction, failure of embryo implantation, endometriosis, and other related pathologies such as polycystic ovary syndrome (PCOS), various environmental factors and inflammatory disease. For this purpose, the rejuvenation of the ovaries using the intraovarian PRP injections may result in increased release of follicles from the available reservoir, and can potentially increase the possibility of a successful pregnancy. Study design, size, duration This study was designed as a randomized prospective observational pilot study. A number of 582 participants were interested to participate. The whole study was performed between May 2018 and December 2021. The patients were subdivided into 5 groups, followeeed by autologous blood collection, PRP preparation and intraovarian injection. The follow-up of the patients lasted for 2 months. Participants/materials, setting, methods The classification of the participants was performed into the following groups: Group A (22-38 years), Group B (39-44 years), Group C (45-57 years), Group D (48-50 years) and Group E (51-56 years). 60 ml of autologous blood was collected from each patient, followed by the preparation of PRP. Intraovarian PRP injection was performed and monitoring of the ovarian function including the quantification of FSH, LH, AMH and E2 for two constitutive menstrual cycles, was performed. Main results and the role of chance For group A, decrease of more than 50% was detected for the FSH and LH whereas, the levels of E2 and AMH were elevated by more than 44% and 31%, respectively in all participants Moreover, statistically significant differences regarding the levels of FSH (p = 0.001), LH (p = 0.046) , E2 (p = 0.035) and AMH (p = 0.012), were observed after the 1st and 2nd month of follow-up. In group B, a statistically significant decrease in FSH (p &amp;lt; 0.001) and LH (p = 0.001) levels were observed in all participants. In parallel, the elevation of E2 and AMH levels was observed. Moreover, 28% of the participants with diagnosed POI, after the PRP infusion, achieved successful pregnancies and live births. In group C, after the PRP infusion, a reduction in FSH and LH levels with a parallel increase of E2 and AMH levels was detected. In group D, the levels of FSH and LH slightly declined after the PRP infusion. Also, the levels of E2 and AMH were increased. In group E, the levels of FSH and LH declin Limitations, reasons for caution No classifications between responders and no responders after the PRP administration were performed. Additionally, no presence of control groups in each category nor the determination of the growth factor content of the produced PRP was performed. The relatively limited time for the follow-up can also be considered a further limitation. Wider implications of the findings The administration of autologous PRP can be considered a safe and tolerable alternative approach to the classical ones for ovarian rejuvenation. This in turn could result to better conceiving rates, thus may beneficially improve the social impact of women with ovarian dysfunction. Trial registration number 10/10/19

Sperm DNA fragmentation (SDF) has been associated with male infertility and poor outcomes of assisted reproductive technology (ART). The purpose of this study was to investigate global practices related to the management of elevated SDF in infertile men, summarize the relevant professional society recommendations, and provide expert recommendations for managing this condition. An online global survey on clinical practices related to SDF was disseminated to reproductive clinicians, according to the CHERRIES checklist criteria. Management protocols for various conditions associated with SDF were captured and compared to the relevant recommendations in professional society guidelines and the appropriate available evidence. Expert recommendations and consensus on the management of infertile men with elevated SDF were then formulated and adapted using the Delphi method. A total of 436 experts from 55 different countries submitted responses. As an initial approach, 79.1% of reproductive experts recommend lifestyle modifications for infertile men with elevated SDF, and 76.9% prescribe empiric antioxidants. Regarding antioxidant duration, 39.3% recommend 4-6 months and 38.1% recommend 3 months. For men with unexplained or idiopathic infertility, and couples experiencing recurrent miscarriages associated with elevated SDF, most respondents refer to ART 6 months after failure of conservative and empiric medical management. Infertile men with clinical varicocele, normal conventional semen parameters, and elevated SDF are offered varicocele repair immediately after diagnosis by 31.4%, and after failure of antioxidants and conservative measures by 40.9%. Sperm selection techniques and testicular sperm extraction are also management options for couples undergoing ART. For most questions, heterogenous practices were demonstrated. This paper presents the results of a large global survey on the management of infertile men with elevated SDF and reveals a lack of consensus among clinicians. Furthermore, it demonstrates the scarcity of professional society guidelines in this regard and attempts to highlight the relevant evidence. Expert recommendations are proposed to help guide clinicians.
