Background: HIV/AIDS pandemic really become danger to mankind on the earth. Objectives: Description epidemiological characteristics of HIV/AIDS patients. Studying clinical expression, learning aboutdemands of infected patients and community care for infected patients. Subjects and method: 71 HIV/AIDS people in Thua Thien Hue were studied in 2006. Using descriptive method to give epidemiological characteristics and behaviour of HIV/AIDS people. People were determined HIV/AIDS infection based on the criteria of Ministry of Health. The information were collected by target study. Results: HIV/AIDS people mainly from the age of 20 to 39 (83,10%), males were 52,10% and in various levels of education and all kinds of occupation. The rate of sexually transmitted infection was 84,5% and infection transmission was 15,5%. The rate of sexually transmitted infection within the last 12 months was 57,7%. 63,4% of infected people used condom while having sex with their spouses or partners. 1,4% of infected people using drug infection within the last month. 38% of the infected people had manifestations of AIDS, 77,8% of HIV/AIDS were treated with antiviral drugs. Families and communities had positive attitudes and behaviors to the HIV/AIDS people. Infected people being remoted from the society was 12,7%, 88,7% of them receiving supports from their communities such as disease treatment, spirit and material supports and job opportunities. Conclusion: Strengthen communication activities to change behavior of HIV/AIDS people and in communitiy to reduce alienation, discrimination for infected people. Execute socialization in care and support for HIV/AIDS people.

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.

Surgical sperm retrieval (SSR) is currently one of the most common procedures in in vitro fertilization (IVF). However, a gap between the guidelines and routine clinical practice regarding antibiotic use in SSR, which might lead to antibiotic resistance, is a challenging problem worldwide. A cross-sectional survey was conducted from May 1, 2021, to July 15, 2021, to investigate antibiotic usage by medical professionals when performing SSR in IVF centers in Vietnam. The confidential questionnaire comprised 12 items, including characteristics of the study population, awareness of antimicrobial resistance, attitude toward prescribing antibiotics, and current practice of prescribing antibiotics when performing SSR. Surveys were completed by 30 of 45 registered IVF centers (66.7%). Among 67 physicians working at those centers, the age and work-experience years (mean ± standard deviation [s.d.]) were 38.6 ± 6.6 years and 11.2 ± 7.0 years, respectively. Over 60% of them held a degree in Obstetrics and Gynecology, and over four-fifths were men. Most respondents "often/very often/always" raised awareness of antimicrobial resistance to their patients (83.3%), but only half of them "often/occasionally" prescribed antibiotics to patients with SSR in cases where the prescription would be optional. About one-tenth of respondents followed the recommendation from the American Urological Association using "prophylaxis only" for SSR patients. For more invasive SSR, physicians tended to prescribe more complicated and sometimes inappropriate regimens. In conclusion, antibiotic usage in SSR was not always appropriate among IVF centers. Further studies may define specific recommendations for regimens, intervention strategies, and programs to promote appropriate antibiotic use for SSR patients among IVF specialists.

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.

BACKGROUND: Polycystic ovarian syndrome (PCOS) is one of the most common endocrinopathies among reproductive-age women. Its metabolic features often overlap with those associated with metabolic syndrome (MS) and insulin resistance syndrome (IRS). The objective of this study was to determine the prevalence and predictors of MS and IRS in infertile Vietnamese women with PCOS. METHODS: A cross-sectional study was conducted at a tertiary fertility centre at Hue University Hospital from June 2016 to November 2017. A total of 441 infertile women diagnosed with PCOS based on the revised 2003 Rotterdam consensus criteria were enrolled. MS and IRS were defined based on the National Heart, Lung, and Blood Institute/American Heart Association Adult Treatment Panel III 2005 and American College of Endocrinology IRS 2003 criteria, respectively. Complete clinical and biochemical measurements of 318 women were available for analysis. Independent predictors of MS and IRS were identified using multivariate logistic regression. RESULTS: The overall prevalence of MS and IRS in women with PCOS was 10.4% and 27.0%, respectively. We identified older age (>30 years) and obesity as independent predictors of MS and IRS. Elevated anti-Müllerian hormone levels increased the risk of IRS, but not that of MS. CONCLUSION: MS and IRS are prevalent disorders among infertile Vietnamese women with PCOS. PCOS is not solely a reproductive problem. Screening and early intervention for MS and/or IRS based on anthropometric, metabolic, and reproductive hormone risk factors should be an integral part of fertility care.

Background: With the development of HIV/AIDS pandemic in community, amount of HIV/AIDS people more and more increase in prison. Objectives: Determine the rate of HIV/AIDS infection of prisoners at Binh Dien prison. Learning about related elements to HIV/AIDS infection. Subjects and method: Prisoners at Binh Dien prison. Method: 492 prisoners were chosen, interviewed directly and taken blood samples to HIV test. Using cross-sectional study on accidental samples. Techniques were used in this study: SERODIA-HIV and ELISA technique. Results: The rate of current HIV/AIDS infections was 21,74%, some HIV/AIDS related factors in the prison included sex, religion, income source, marrital status, common knowledge of HIV/AIDS, drug addiction history, needle sharing, sexually transmitted disease history, body tatoos and forskin inserted with metal balls, alcohol and beer drinking history, some factors such as: age and educational level were not associated with HIV/AIDS infection in prison. Conclusion: Strengthen interventional activities in prison to prevent HIV/AIDS spread between prisoners. To prisoners who were not infected HIV/AIDS: strengthen educational communication to they may prevent themselves from HIV/AIDS infection behaviors. To HIV/AIDS prisoners: Need to educate and consult especially to they have right behaviors, prevent HIV/AIDS spread for the others while they were in prison as well as they return to society.

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 develop a configurable clean room paradigm with low air pressure for assisted reproductive technology (ART) clinics and demonstrate the concept’s efficacy using in vitro fertilization (IVF) treatment. Methods: A high-standard clean room system with positive pressure (13 Pa) was built using accessible materials and equipment for ART laboratories. Methods for controlling and evaluating the clean room’s characteristics were developed and implemented for quality assessment and calibration to maximize efficiency. The feasibility of the flexible clean room concept was assessed by analyzing the key performance indicators of embryo culture and IVF treatment. Results: After 3 weeks of testing, the concentration of particles ≥0.5 μm was 6.04 times lower than the International Organization for Standardization (ISO) class 5 standard (3,520 particles/m3) in the IVF laboratory. Air pressure, noise, temperature, and humidity were controlled stably and appropriately. Five days after installation and handover, the volatile organic compound concentration dropped to 0.00 ppm. With blastocysts and a respectable blastocyst rate, embryonic culture with female patients younger than 40 matched the criteria (63.5% and 38.9%, respectively). After vitrified blastocysts were transferred, the pregnancy and implantation rates were 58.5% and 36.2%, respectively, demonstrating a high degree of treatment success. Conclusion Our customizable, high-quality, low-air-pressure clean room model can be implemented to achieve positive outcomes for infertility treatment.

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.
