Sinus of Valsalva aneurysm is a rare entity and can be congenital or acquired. The disease can progress silently until the aneurysm ruptures, finally causing symptoms. Once ruptured, if such an aneurysm is not treated timely, the patient will progress to left heart failure. We discuss a 61-year-old male who presented with increasing dyspnea over 2 months. He underwent uncommon, less invasive interventional treatment and made a full recovery in a brief period. His condition of combined rupture of the sinus of Valsalva and bicuspid aortic valve was very rare.

Objective: The purpose of this study was to identify factors associated with twin pregnancy following day 3 double embryo transfer (DET). Methods: This retrospective cohort study incorporated data from 16,972 day 3 DET cycles. The participants were women aged between 18 and 45 years who underwent in vitro fertilization with intracytoplasmic sperm injection (IVF/ICSI) at My Duc Assisted Reproduction Technique Unit (IVFMD), My Duc Hospital, located in Ho Chi Minh City, Vietnam. Results: Of the 16,972 day 3 DET cycles investigated, 8,812 (51.9%) resulted in pregnancy. Of these, 6,108 cycles led to clinical pregnancy, with 1,543 (25.3% of clinical pregnancies) being twin pregnancies. Factors associated with twin pregnancy included age under 35 years (odds ratio [OR], 1.5; 95% confidence interval [CI], 1.32 to 1.71; p<0.001) and cycles involving the transfer of at least one grade I embryo. Relative to the transfer of two grade III embryos, the risk of twin pregnancy was significantly elevated following the transfer of two grade I embryos (OR, 1.40; 95% CI, 1.16 to 1.69; p<0.001) or a combination of one grade I and one grade II embryo (OR, 1.27; 95% CI, 1.05 to 1.55; p=0.001). Conclusion: By analyzing a large number of IVF/ICSI cycles, we identified several predictors of twin pregnancy. These findings can assist medical professionals in tailoring treatment strategies for couples with infertility.

This paper reports the successful fabrication of deposited Glass/ZnO/CdS/CuInS<sub>2</sub> solar cells with superstrate structure using Full Spray Pyrolysis Deposition (FSPD). The structure, optical and electrical properties of the constituent layers are investigated. It is observed that the CuInS<sub>2</sub> (CIS) film deposited from starting solution with [Cu]/[In] = 1.1, and Al-doped CuInS<sub>2</sub> (CIAS) film deposited from solution with [Cu]/[In] = 1.0, [Al]/[In] = 0.12, and using sulfurization process exhibited the best crystallites with tetragonal structure. The optical band gap of the CIAS film is obtained as 1.49 eV. Some physical properties of both ZnO, and CdS thin films are also studied. The parameters of the cells obtained are V<sub>OC</sub> = 425 mV, J<sub>SC</sub> = 14.02 mA/cm<sup>2</sup>, FF = 28.75% and efficiency of 1.71%. The results in our experiment show that FSPD is a potential technique to prepare solar cells based on CIS absorbers in a superstrate structure with low cost and high performance.

Objective: This study aimed to investigate the impact of hyperandrogenism (HA) on the outcomes of ovulation induction (OI) using gonadotropin and intrauterine insemination (IUI) in patients with polycystic ovary syndrome (PCOS). Methods: This was a retrospective cohort study including 415 patients undergoing OI using gonadotropin and IUI treatment between January 2018 and December 2020 at a single infertility center. Baseline characteristics, clinical and laboratory parameters, and pregnancy outcomes were investigated. Results: Among the study population, there were 105 hyperandrogenic (25.3%) and 310 non-hyperandrogenic patients (74.7%). The live birth rate was lower in the HA group than in the non-HA group, but this difference did not reach statistical significance due to the limited sample size (14.3% vs. 21.0%, relative risk=0.68; 95% CI, 0.41-1.14, p=0.153). No predictive factors for live birth were identified through logistic regression analysis. Conclusion: HA did not negatively affect the outcomes of OI using gonadotropin and IUI cycles in Vietnamese women with PCOS. The result may not be applicable elsewhere due to the large variation in the characteristics of women with PCOS across races and populations.
