Objective: The objective of this study was to evaluate the association between cervical management strategies, specifically pessary placement, cervical cerclage, or expectant management, and gestational age at delivery in twin pregnancies and to assess the prognostic value of cervical characteristics for early preterm birth (<33 weeks). Methods: We conducted a retrospective cohort study including 120 twin pregnancies managed at a tertiary referral center between 2019 and 2024. Pregnancies with positive vaginal or cervical microbiological cultures or abnormal cervical cytology were excluded. The management strategy was selected based on cervical characteristics and clinical judgment. Gestational age at delivery was compared across intervention groups using descriptive statistics, kernel density plots, boxplots, and Kaplan-Meier survival analysis. Multivariable Cox proportional hazards regression was performed to estimate adjusted hazard ratios (HRs) for early delivery, including intervention type and cervical parameters (length, diameter, and funneling). Results: Overall, 26 of 120 pregnancies (21.6%) resulted in delivery before 33 weeks. Pessary placement was associated with longer gestational duration compared with cerclage or expectant management. Kaplan-Meier analysis demonstrated a clear separation of survival curves by intervention group, with the pessary group maintaining pregnancy to later gestational ages (log-rank p < 0.001). In multivariable Cox regression analysis, pessary use was associated with a significantly lower hazard of early delivery compared with cerclage (HR = 0.088, 95% CI: 0.035-0.220; p < 0.001). Expectant management showed a trend toward an increased risk of early delivery (HR = 2.44; p = 0.067). Cervical length and diameter were not independently associated with early delivery after adjustment for intervention type. Funneling was associated with a lower hazard of early delivery, a finding that warrants cautious interpretation. Conclusions: In this retrospective cohort of twin pregnancies without microbiological evidence of infection, pessary placement was associated with prolonged gestation and a lower hazard of early preterm delivery compared with cerclage or expectant management. These findings support a personalized, risk-adapted approach to cervical intervention selection in twin pregnancies. Prospective, randomized studies incorporating etiologic stratification are needed to confirm these associations and guide clinical practice.

Non-optimized encapsulation parameters, set during the lamination process, can be a cause of multiple failure modes for PV modules in the field. This paper investigates the influence of a double-side heating system in the lamination process for a glass-backsheet PV module. This effect was evaluated by comparing the gel content of encapsulants treated with different heating methods, including single-side and double-side heating systems. Towards this goal, forty different lamination process recipes are tested using various temperatures and process times to compare the gel content of the ethylene vinyl acetate (EVA) encapsulant and find the fastest possible lamination process. The gel content is determined using Soxhlet extraction, while the degree of crosslinking is assessed using differential scanning calorimetry (DSC), and the results are compared. The results show that double-side heating can shorten the process time by 10% to 30%. Furthermore, the paper examines the potential of reducing the process time by performing temperature uniformity measurements during the process and laminating full-size modules for visual inspection using a double-side heating system. It was found that temperatures above 165 °C can be used for a stable lamination process using EVA encapsulant and polyethylene terephthalate (PET) based polymer backsheet. Based on the above results, a five-minute one-step single-press lamination process plus cooling is demonstrated. Long-term stability and safety tests are further studied according to IEC 61215-2 and IEC 61730-2 standards, respectively. The modules successfully passed the standard qualification tests, including thermal cycling, damp-heat, and mechanical load tests following damp-heat exposure, with a maximum power degradation (PMPP) of less than 2%. All the insulation characterizations, including the dry insulation test and wet leakage current test, were also successfully completed following the safety tests, which included sequence B and sequence B1.

Background/Objectives: In recent years, there has been a noticeable increase in the rates of caesarean section (CS), being one of the most commonly performed surgical procedures. For the following pregnancy, the previous CS represents the backbone of the risks and complications, such as uterine scar formation, uterine rupture, massive bleeding, and serious negative outcomes for both the mother and child. Our study followed patients with a history of CS from the birth planning prenatal check-up to delivery. Methods: We reviewed the records of 125 pregnant women with previous CS who presented in the third trimester for a prenatal check-up and completed our questionnaire from March 2021 to April 2022 in the Clinic of Obstetrics and Gynecology, Diakoneo Diak Klinikum Schwäbisch Hall, Germany. Results: Before the prenatal check-up, 74 patients (59.2%) preferred vaginal delivery (VD), while 51 (40.8%) preferred CS. After discussing birth planning with the obstetrician, 72 women (57.6%) decided upon VD, while 53 (42.4%) preferred CS. Ultimately, 78 (62.4%) of women gave birth through CS (either planned or by medical necessity) and 47 (37.6%) gave birth vaginally (either natural or per vacuum extraction). Conclusions: VD for patients with CS in their medical history is a real option. The patient must be well informed about the risks and benefits of the medical situation and should be empowered and supported on their chosen mode of delivery, which should be respected.

Pulmonary vein isolation (PVI) using cryoballoon ablation (CBA) is an established procedure for treating symptomatic paroxysmal and persistent atrial fibrillation (AF). The safety and efficacy of PVI performed at community hospitals are unknown. We aimed to determine the safety and acute efficacy of PVI using CBA performed at community hospitals with limited annual case numbers. This registry study included 1004 consecutive patients who had PVI performed for symptomatic paroxysmal (n = 563) or persistent AF (n = 441) from January 2019 to September 2020 at 20 hospitals. Each hospital performed fewer than 100 CBA-PVI procedures/year according to local standards. Procedural data, efficacy, and complication rates were determined. The mean number of CBA procedures performed/year at each centre was 59 ± 25. The average procedure time was 90.1 ± 31.6 min and the average fluoroscopy time was 19.2 ± 11.4 min. Isolation of all pulmonary veins was documented in 97.9% of patients. The most frequent reason for not achieving complete isolation was development of phrenic nerve palsy. No hospital deaths were observed. Two patients (0.2%) suffered a clinical stroke. Pericardial effusion occurred in six patients (0.6%), two of whom (0.2%) required pericardial drainage. Vascular complications occurred in 24 patients (2.4%), two of whom (0.2%) required vascular surgery. Phrenic nerve palsy occurred in 48 patients (4.8%) and persisted up to hospital discharge in six patients (0.6%). Pulmonary vein isolation procedures for paroxysmal or persistent AF using CBA can be performed at community hospitals with high acute efficacy and low complication rates.

More than 90% of human pancreatic cancers carry the oncogenic mutant of Ki-RAS and their growth depends on its downstream kinase PAK1, mainly because PAK1 blocks the apoptosis of cancer cells selectively. We developed a highly cell-permeable PAK1-blocker called 15K from an old pain-killer (ketorolac), that is shown here to inhibit the growth of three pancreatic cancer cell lines with IC50 values ranging 41-88 nM in vitro. The anti-cancer effect of 15K was further investigated in an orthotopic xenograft model with gemcitabine (GEM)-resistant human pancreatic cancer cell lines (AsPC-1 and BxPC-3) expressing luciferase in athymic mice. During 4 weeks, 15K blocks total burden (growth) of both AsPC-1 and BxPC-3 tumors (measured as radians/sec) with the IC50 below daily dose of 0.1 mg/kg, i.p. In a similar manner 15K reduced both their invasion and metastases as well, while it had no effect on either body weight or hematological parameters even at 5 mg/kg/day. To the best of our knowledge, 15K is so far the most potent among synthetic PAK1-blockers in vivo, and could be potentially useful for therapy of GEM-resistant cancers.
