Background: Domestic-related violence against women appears in every country, culture and socioeconomic classes. Yen Phong district of Bac Ninh province is in the economic transformation process from agricultural to industrial and service economic structure. The domestic-related violence trend is increasing, but there are no study on this situation. Objectives: The study was conducted to investigate the situation of domestic violence against women in Yen Phong district, Bac Ninh province. Subjects and method: The study used cross-sectional descriptive design. Participants were married women who were less than 50 years old. The participants were interviewed with structured questionnaires. The group involved the men who have a history of violent activities against women and the women who suffered from violence was thoroughly interviewed and discussed. Results: A total of 452 women had participated in the study. Mean age of participants was 34.6 years old (ranging from 19 to 49 years old). About half of participants have never suffered from domestic violence. The violence in the last 12 months was lower, affected to one out of every 5 women. The mental violence accounted for highest rate, followed by physical and sexual violence (29.2%, 28.3% and 10.4%, respectively). Sharing economy and household responsibility, gambling habit of husbands and talkative habit of wives were main reasons of violence. The consequences of violence were mainly related to mental and social factors. Some women suffered from mental, physical and sexual health consequences (73.2%, 20.5%, and 13.7%, respectively). Conclusion: In order to increase the awareness on domestic violence, it requires improve access to information on gender violence for both men and women.

Background: Domestic violence is a common occurrance in every country, culture and all levels of society, and about 20%-50% of women worldwide are victims of domestic violence. In Vietnam, domestic violence had broad range of influences and has serious impacts. Objectives: To identify the factors influencing domestic violence in Yen Phong district, Bac Ninh province. Subjects and method: A cross-sectional study was conducted in 2006 on 452 married women aged 19 to 45 years, with structured questionnaire and in-depth interviews and focus group discussion. Results and conclusion: the lifetime prevalence of domestic violence was 42% and the prevalence in the past 12 month was 22.6%. The most frequent domestic violence was mental, followed by physical and sexual violence. The first 15 years of marriage was the most turbulent period of violence. There were significant relationships between lifetime violence and the education, occupation, economic status, but there was no relationship for violence in the past 12 months. The women, whose husbands were drunk, gambling and unfaithful, were more likely to be facing domestic violence than the others. The acceptance of violence by women was significantly related to violence. Those who perceived the violence by husbands were very severe then were less likely to be faced by violence than the other. In order to prevent the domestic violence, it is necessary to promote the health education, improving the awareness of women and men on gender equity and equality.

Background: Gastric cancer is a common disease in the world. For treatment, gastrectomy is still considered as the first choice. However, recovering of postoperative gastrointestinal circulation remains a controversial issue. Objectives: To assess the early results of 2 methods as gastroduodenostomy (Billroth I type) and gastrojejunostomy (Billroth type II) in recovering of gastrointestinal circulation. Subjects and method: A descriptive, retrospective study was conducted on 98 patients (61 males, 37 females, mean aged 48.1\xb112.7), were confirmed diagnosed with gastric cancer, treated in Military Central Hospital N.108 from May, 2001 to December, 2005. Results: Tumor positions were seen in 1/3 lower and 1/3 middle of gastric organ (59.2% and 40.8%, respective). There was no significant difference for invasive level of tumor between 2 groups (P>0.05). 62.2% patients with invasive level of tumor in stage of T4 in both 2 groups. Generally, the lesion between 2 forms of ulcer and rough differed significantly. The patients with and without metastatic lymph nodes were 57 and 41 patients, respective. All of patients were conducted with lymph node dissection at the stage of DIII-DIV. The difference between 2 groups for surgical time was no statistic significant. Conclusion: Billroth type I method combined with lymph nodes dissection was a safe and feasible technique in treatment of gastric cancer.

OBJECTIVE: Sperm cryopreservation has been widely used in assisted reproductive technology, as it offers great potential for the treatment of some types of male infertility. However, cryopreservation may result in changes in membrane lipid composition and acrosome status, as well as reductions in sperm motility and viability. This study aimed to evaluate sperm DNA fragmentation damage caused by conventional freezing using the sperm chromatin dispersion test. METHODS: In total, 120 fresh human semen samples were frozen by conventional methods, using SpermFreeze Solution as a cryoprotectant. Routine semen analysis and a Halosperm test (using the Halosperm kit) were performed on each sample before freezing and after thawing. Semen parameters and sperm DNA fragmentation were compared between these groups. RESULTS: There was a significant decrease in sperm progressive motility, viability, and normal morphology after conventional freezing (32.78%, 79.58%, and 3.87% vs. 16%, 55.99%, and 2.55%, respectively). The sperm head, midpiece, and tail defect rate increased slightly after freezing. Furthermore, the DNA fragmentation index (DFI) was significantly higher after thawing than before freezing (19.21% prior to freezing vs. 22.23% after thawing). Significant increases in the DFI after cryopreservation were observed in samples with both normal and abnormal motility and morphology, as well as in those with normal viability. CONCLUSION: Conventional freezing seems to damage some sperm parameters, in particular causing a reduction in sperm DNA integrity.

OBJECTIVE: In frozen and thawed embryos, the zona pellucida (ZP) can be damaged due to hardening. Laser-assisted hatching (LAH) of embryos can increase the pregnancy rate. This study compared thinning and drilling of the ZP before frozen embryo transfer (FET). METHODS: Patients were randomly allocated into two groups for LAH using thinning or drilling on day 2 after thawing. Twenty-five percent of the ZP circumference and 50% of the ZP thickness was removed in the thinning group, and a hole 40 µm in diameter was made in the drilling group. RESULTS: A total of 171 in vitro fertilization/intracytoplasmic sperm injection FET cycles, including 85 cycles with drilling LAH and 86 cycles with thinning LAH, were carried out. The thinning group had a similar β-human chorionic gonadotropin-positive rate (38.4% vs. 29.4%), implantation rate (16.5% vs. 14.4%), clinical pregnancy rate (36.0% vs. 25.9%), miscarriage rate (5.8% vs. 2.4%), ongoing pregnancy rate (30.2% vs. 23.5%), and multiple pregnancy rate (7.0% vs. 10.6%) to the drilling LAH group. There were no significant differences in pregnancy outcomes between subgroups defined based on age (older or younger than 35 years) or ZP thickness (greater or less than 17 µm) according to the LAH method. CONCLUSION: The present study demonstrated that partial ZP thinning or drilling resulted in similar outcomes in implantation and pregnancy rates using thawed embryos, irrespective of women's age or ZP thickness.

As the associations of sperm DNA fragmentation with morphology have not been examined in detail, this study aimed to investigate the relationship between abnormalities of morphological details and DNA integrity in human sperm. Methods: In this cross-sectional study, men from infertile couples were enrolled at Hue Center for Reproductive Endocrinology and Infertility, Vietnam. Conventional semen parameters, including morphological details, were analyzed following the World Health Organization 2010 criteria. Sperm DNA fragmentation was evaluated using a sperm chromatin dispersion assay. The relationships and correlations between semen parameters, sperm morphology, and the type of halosperm and the DNA fragmentation index (DFI) were analyzed. Results: Among 130 men in infertile couples, statistically significant differences were not found in the sperm halo type between the normal and abnormal sperm morphology groups. The percentage of round-head spermatozoa was higher in the DFI >15% group (16.98%±12.50%) than in the DFI ≤15% group (13.13% ±8.82%), higher values for amorphous heads were found in the DFI >15% group, and lower values for tapered heads were observed in the DFI ≤15% group; however, these differences were not statistically significant. Small-halo sperm and the DFI were positively correlated with round-head sperm (r=0.243, p=0.005 and r=0.197, p=0.025, respectively). Conclusion: The rate of general sperm morphological abnormalities in semen analysis was not related to sperm DNA integrity. However, round sperm heads were closely associated with sperm DNA fragmentation.

Objective: This study aimed to compare the efficacy of physiological intracytoplasmic sperm injection (PICSI) and intracytoplasmic sperm injection (ICSI) in terms of the fertilization rate and embryo quality using sibling oocyte cycles. Methods: This prospective, cross-sectional study collected data from 76 couples who underwent their first cycle at the Hue Center for Reproductive Endocrinology and Infertility, Vietnam, between May 2019 and November 2021. The inclusion criteria were cycles with at least eight oocytes and a sperm concentration of 5×106/mL. Sperm parameters, sperm DNA fragmentation (SDF), fertilization, and the quality of cleavage-stage embryos on day 2 and blastocysts on day 5 were examined. Results: From 76 ICSI cycles, 1,196 metaphase II (MII) oocytes were retrieved, half of which were randomly allocated to either the PICSI (n=592) or ICSI (n=604) treatment group. The results showed no significant difference between the two groups in terms of fertilization (72.80% vs. 75.33%, p=0.32), day 2 cleavage rate (95.13% vs. 96.04%, p=0.51), blastulation rate (52.68% vs. 57.89%), and high-quality blastocyst rate (26.10% vs. 31.13%, p=0.13). However, in cases where SDF was low, 59 cycles consisting of 913 MII oocytes produced a considerably higher blastulation rate with PICSI than with ICSI (50.49% vs. 35.65%, p=0.00). There were no significant differences between the pregnancy outcomes of the PICSI and ICSI embryo groups following embryo transfer. Conclusion Using variable sperm quality provided no benefit for PICSI versus ICSI in terms of embryo outcomes. When SDF is low, PICSI appears to be able to produce more blastocysts.
