Summary: The noninvasive fetal electrocardiogram (FECG) is difficult to obtain due to the interference of the maternal electrocardiogram (MECG) and noise in the abdominal electrocardiogram (AECG). In this study, an adaptive amplitude-frequency attention network (AAFA-Net) was proposed to extract FECG signals from AECG signals. Experimental results demonstrate the superiority of the proposed method over existing approaches.

Summary: This study investigated the association and potential value of prelabour fetal heart rate short-term variability (STV) determined by computerised cardiotocography (cCTG) and maternal and fetal Doppler in predicting labour outcomes. The results showed a weakly positive correlation between prelabour STV and umbilical cord arterial pH, but it was not predictive of emergency delivery due to pathological CTG during labour.

Summary: Early detection and treatment of fetal cardiac diseases and heart abnormalities is crucial during pregnancy. This study proposes a non-invasive fECG monitoring system using WiFi transmission and Raspberry Pi 3 for real-time analysis of extracted fetal electrocardiogram signals. The method of Independent Component Analysis and Wavelet Transform is used for noise reduction and signal extraction. The results demonstrate the effectiveness of the proposed algorithm and suggest its use in portable fECG monitoring systems.

Summary: This study presents a system for continuously monitoring fetal heart rate without specifying the location of the Doppler ultrasound transducer. An algorithm is developed to track the fetal heart location based on the intensity of the received Doppler signal. The performance of the system is evaluated through underwater experiments, showing that the fetal heart rate can be continuously recorded even with tracking errors.

Summary: This study identified an effective method for extracting non-invasive fetal electrocardiogram (NI-fECG) from signals recorded from the mother's abdomen, combining independent component analysis (ICA), fast transversal filter (FTF), and complementary ensemble empirical mode decomposition with adaptive noise (CEEMDAN). Testing on two patient databases demonstrated that this combined method is capable of accurately extracting fECG with lower computational complexity.

Summary: This study aims to validate the ICH and ICH-GS scores in patients with cerebellar hemorrhage and compare the outcomes of surgical management with conservative treatment. The results showed that both ICH and ICH-GS scores have good prognostic accuracy for overall mortality and functional outcomes. Surgical management was beneficial for patients with severe cerebellar hemorrhages, indicated by high ICH scores, while conservative treatment was reasonable for patients with lower ICH scores. Therefore, ICH and ICH-GS scores are useful tools for predicting survival and outcome in cerebellar ICH patients.

Summary: The Weil osteotomy is commonly performed for chronic metatarsalgia, and screw fixation is historically used for metatarsal head refixation. However, this study suggests that screw fixation is not always necessary. Retrospective analysis of 155 patients with 278 Weil osteotomies demonstrated a lower revision rate in patients without screw fixation. Therefore, regular screw fixation after a Weil osteotomy may not be justified based on the available data.

Summary: Posttraumatic osteoarthritis may require surgical fusion of the ankle joint if non-surgical therapy is unsuccessful. The decision to perform fusion is based on the patient's pain and disability, radiographic imaging, and surgeon experience, without strict guidelines. This study compared outcomes of tibiotalocalcaneal arthrodesis (TTCA) and tibiotalar arthrodesis (TTA) to highlight the importance of the subtalar joint. The results showed significantly worse clinical scores in the TTCA group compared to the TTA group, indicating the need for careful consideration of generous subtalar joint fusion with planned ankle arthrodesis.

Summary: Joint destruction necessitates tibiotalocalcaneal arthrodesis (TTCA) in cases of clinical deficits that cannot be controlled conservatively, possibly leading to sepsis. We aimed to compare the underlying etiology of posttraumatic joint destruction and the outcomes after TTCA in patients with a septic or aseptic history. The significantly worse results of S-TTCA compared to A-TTCA show the long and stressful ordeal that patients with a septic history suffer. Further attention must be paid to infection prophylaxis and, if necessary, early infection revision.

Summary: The purpose of this study was to observe the quality of posterior composite restorations after more than 23 years of service. A total of 22 patients with 42 restorations underwent two follow-up examinations. Results showed significantly worse scores for six out of seven criteria at the second follow-up evaluation. The study suggests the need for further research with extended follow-up time and regular assessments.

Summary: Background & Aims: This study aimed to investigate the transmission and characteristics of recently acquired HCV infections (RAHCs) over a 10-year period. The majority of RAHC cases were found in HIV-coinfected men who have sex with men (MSM), and internationally connected transmission networks were observed in most patients. Spontaneous clearance rates were low, and reinfection rates increased in a subset of MSM patients with high-risk behavior.
