The Impact of Seasonal Variation on Clinical Pregnancy and Live Birth Rates in Assisted Reproductive Technology: A Retrospective Cohort Study in Hainan

Objective:To investigate the influence of season on live birth and clinical pregnancy rates,as well as assisted reproductive technology(ART)outcomes,in the Hainan region.Methods:Patients were categorized into four groups based on the dates of artificial insemination and transplantation:spring,summer,autumn,or winter.The main outcome measures were clinical pregnancy rates and live birth rates.Secondary outcomes included body mass index(BMI),oocyte number,two pronuclei(2PN)cleavage rate,total gonadotropin(Gn)dosage and days,age,2PN fertilization rate,sperm concentration,sperm PR rate,anti-Müllerian hormone(AMH),and endometrial thickness.Outpatient semen quality indicators included sperm PR rate,total sperm count,sperm concentration,and total sperm motility.Results:This retrospective cohort study analyzed 2,016 artificial insemination cycles and 1,783 ovarian retrieval cycles from January 2017 to October 2022,and assessed the semen quality of 6,651 outpatients from May 2017 to October 2022.In artificial insemination cycles,sperm PR rate and clinical pregnancy rate were highest in winter,with a statistically significant difference between groups(P<0.05).Clinical pregnancy rate was influenced by both age and sperm PR rate(P<0.05).In ovarian retrieval cycles,the winter group had significantly higher clinical pregnancy,2PN fertilization,and 2PN cleavage rates than the other groups.The autumn group had higher live birth rates,though not significantly different.Additionally,winter months showed higher total sperm concentration and total sperm number compared to other seasons.Conclusion:Seasonality affected clinical pregnancy and live birth rates in artificial insemination cycles but not in ovarian retrieval cycles in the Hainan region.These findings suggest that while there is no need to choose a specific season for ovarian retrieval cycles,artificial insemination in winter may be preferable for patients.

A Short Review of the Literature on Assistive Technologies for Alzheimer’s Patients and Their Caregivers

Alzheimer’s is one of the most disabling neurocognitive diseases. A person diagnosed with Alzheimer’s slowly loses cognitive function and ultimately becomes entirely dependent upon the caregivers. Caregivers must help the patient in everyday activities ranging from walking to cooking, eating, and so on. In most caregiving facilities, a single caregiver often handles more than one patient, which results in caregiver burnout. Researchers are developing useful technologies to prevent caregiver burnouts and facilitate families in the best possible manner. The goal of this purposive short review of literature is to study the modern tools, devices, and gadgets available to Alzheimer’s patients and caregivers and understand the focus areas for future research. The review identified a range of products and technologies that help in monitoring to diagnosis, aid therapy, and reduce the burden on caregivers. These technologies play a vital role in improving the quality of life for both the patients and the caregivers. The study identified reducing cost of the devices, increasing robustness and dependability of the devices, and various aspects of the assistive technologies, including ethical and privacy issues, as the focus areas for future research.

Assisted Reproductive Technology for HIV-1 Serodiscordant Couples: A Review of Current Controversies

Since 1992, assisted reproductive technology （ART） has been reported as a viable means of helping HIV-1 serodiscordant couples achieve pregnancy while theoretically reducing the risk for viral transmission. While the sum of the evidence suggests that ART is effective and safe, numerous controversies still exist, The follow- ing review addresses several of the important issues involved in the use of ART for HIV-serodiscordant couples, including patient selection, semen processing techniques, post-process HIV testing, the use of lUI vs IVF-ICSI.

Embryo quality and chromosomal abnormality in embryos from couples undergoing assisted reproductive technology using preimplantation genetic screening

Objective:To detect common chromosomal aneuploidy variations in embryos from couples undergoing assisted reproductive technology and preimplantation genetic screening and their possible associations with embryo quality.Methods:In this study,359 embryos from 62 couples were screened for chromosomes 13,21,18,X,and Y by fluorescence insitu hybridization.For biopsy of blastomere,a laser was used to remove a significantly smaller portion of the zona pellucida.One blastomere was gently biopsied by an aspiration pipette through the hole.After biopsy,the embryo was immediately returned to the embryo scope until transfer.Embryo integrity and blastocyst formation were assessed on day 5.Results:Totally,282 embryos from 62 couples were evaluated.The chromosomes were normal in 199(70.57%)embryos and abnormal in 83(29.43%)embryos.There was no significant association between the quality of embryos and numerical chromosomal abnormality(P=0.67).Conclusions:Embryo quality is not significantly correlated with its genetic status.Hence,the quality of embryos determined by morphological parameters is not an appropriate method for choosing embryos without these abnormalities.

Clinical study of different fertilization methods of assisted reproductive technology on neonatal birth defects

Objective:To investigate the incidence of neonatal birth defects in assisted reproductive technology(ART)by in vitro fertilization(IVF)and intracytoplasmic sperm injection(ICSI).Methods:The clinical data of 4229 cases of singleton deliver by infertile patients under 35 years old who received IVF/ICSI-ET in our center were analyzed.According to different fertilization methods,they were divided into IVF group(2967 cases)and ICSI group(1262 cases).The general situation of birth,birth defects and the location of defects were compared between the two groups.Results:a total of 38 cases of neonatal birth defects were found,the incidence of birth defects was 0.89%,including 30 cases(1.01%)in IVF group and 8 cases(0.64%)in ICSI group.There was no significant difference in the incidence of birth defects between the two groups(P>0.05).There was also no significant difference in birth weight,gestational age and gender ratio between the two groups(P>0.05).Conclusion:Different fertilization methods in assisted reproductive technology do not increase the incidence of neonatal birth defects.

Implementation and Evaluation of Infertility Reflection in Early Pregnancy after the Use of Assisted Reproductive Technology: A Feasibility Study

Background: This study aims to evaluate the infertility reflection in early pregnancy after assistive reproductive therapy (ART), including 1) process evaluation (the use and evaluation of infertility reflection) and 2) outcome evaluation (satisfaction of care needs, anticipatory anxiety towards the loss of a pregnancy or fetus, cognition of infertility experience, and depression and anxiety). Methods: This program evaluation study used a one-group pre-post-test design. The participants were 50 primiparas who had undergone ART at two fertility treatment facilities in a metropolitan area in Japan. For the infertility reflection, they conducted an online reflection. Data were collected three times: at the 5th week of pregnancy (Time 1), the 8th week of pregnancy as the final consultation at the clinic (Time 2), and the 16th week of pregnancy as the final point of early pregnancy (Time 3). Results: The data from 40 participants were analyzed. More than 80% of the users of the online reflection positively evaluated the appropriateness and usefulness of the methods and contents. Organized thoughts and feelings by reflection were shown as the reasons for the usefulness. The evaluation of the online reflection showed a relatively strong correlation with the Care Need Satisfaction Scale (CNSS) for both Time 2 and Time 3, but the online reflection did not show a significant correlation with the other outcome variables. There were no significant differences in outcome variables between users and non-users of online reflection between Time 2 and Time 3. Conclusions: Attempts at the reflection in early pregnancy require modified methods that do not have a negative impact and lead to the fulfillment of needs.

Pregnancies Outcome after Assisted Reproductive Technology: A Multicenter Case Control Study in a Low Income Setting Douala, Cameroon

The objective was to assess the outcome of pregnancies after assisted reproductive technology (ART). It was a case-control study carried out in four health facilities in Douala-Cameroon, over a period of five years. The cases were pregnant women who conceived through ART and the controls were those who conceived naturally. Cases and controls were matched for maternal age and parity (one case for two controls). A logistic regression analysis was used to compute Odds ratios. Statistical significance was set at 0.05. A total of 174 women who conceived through ART and 348 who conceived naturally were enrolled. Some independent factors associated with ART were: age over 45 years [aOR: 7.55; 95% CI (1.55 - 36.76);p: 0.01], twin pregnancies [aOR: 16.55; 95% CI (7.91 - 34.60);p < 0.01], Cervical cerclage [aOR: 3.04; 95% CI (1.23 - 7.50);p: 0.01], miscarriages [aOR: 11.73; 95% CI (5.07 - 27.10);p: 0.01], elective cesarean section [aOR: 4.63; 95% CI (2.27 - 9.45);p: 0.01] and low birth weight [aOR: 3.32; 95% CI (1.90 - 5.82);p < 0.01]. Women who conceived by ART were older with higher rates of multiple pregnancy and complications. We recommend transfer of a single embryo.

Support from Healthcare Professionals for Couples/Partners Undergoing Assisted Reproductive Technology in Japan: A Literature Review

Background and Purpose: A growing number of couples/partners have been undergoing assisted reproductive technology (ART) in Japan. The purpose of this study was to clarify the support from healthcare professionals based on the support vectors in the Family Care/Caring Theory proposed by Hohashi (2015) through a literature review. Methods: Using Ichushi-Web, we searched for original articles using the keywords “assisted reproductive technology”, “infertility”, “family”, “couple”, “nursing”, “care”, and “support”. Thirteen articles suitable for the purpose of this study were subjected to content analysis. Family support was encoded and grouped into subcategories and categories, and classified according to support vectors. Results: A total of 21 categories of support from healthcare professionals was extracted. Intervention for family internal environment included seven categories, such as “Nursing professionals stay close to females”. Intervention for family system unit included five categories, such as “Nursing professionals adjust couple/partner relationships”. Intervention for micro system only included “Nursing professionals provide opportunities for peer support to the couples/partners” and intervention for macro system only included “Nursing professionals encourage medical doctors to relate to females”. Intervention for family chrono environment included seven categories, such as “Healthcare professionals resolve female’s anxieties”. Conclusion: The support from healthcare professionals could be organized by the support vectors of Family Care/Caring Theory, but intervention for supra system (culture, religion, etc.) was lacking. Moreover, because most support was directed toward females or couples/partners, male-focused direct and/or indirect support are also needed. .

Microfluidic thermotaxic selection of highlymotile sperm and in vitro fertilization

The selection of the most motile and functionally competent sperm is an essential basis for in vitro fertilization(IVF)and normal embryonic development.Widely adopted clinical approaches for sperm sample processing intensely rely on centrifugation and wash steps that may induce mechanical damage and oxidative stress to sperm.Although a few microfluidic sperm sorting devices may avoid these adverse effects by exploiting intrinsic guidance mechanisms of sperm swimming,none of these approaches have been fully validated by clinical-grade assessment criteria.In this study,a microfluidic sperm sorting device that enables the selection of highly motile and functional sperm via their intrinsic thermotaxis is presented.Bioinspired by the temperature microenvironment in the fallopian tube during natural sperm selection,a microfluidic device with controllable temperature gradients along the sperm separation channel was designed and fabricated.This study investigated the optimal temperature conditions for human sperm selection and fully characterized thermotaxis-selected sperm with 45 human sperm samples.Results indicated that a temperature range of 35–36.5℃along the separation channel significantly improves human sperm motility rate((85.25±6.28)%vs.(60.72±1.37)%;P=0.0484),increases normal sperm morphology rate((16.42±1.43)%vs.(12.55±0.88)%;P<0.0001),and reduces DNA fragmentation((7.44±0.79)%vs.(10.36±0.72)%;P=0.0485)compared to the nonthermotaxis group.Sperm thermotaxis is species-specific,and selected mouse sperm displayed the highest motility in response to a temperature range of 36–37.5℃ along the separation channel.Furthermore,IVF experiments indicated that the selected sperm permitted an increased fertilization rate and improved embryonic development from zygote to blastocyst.This microfluidic thermotaxic selection approach will be translated into clinical practice to improve the IVF success rate for patients with oligozoospermia and asthenozoospermia.

Attitude and willingness on gamete donation among medical students:An experience from a state university in Sri Lanka

Objective:To assess the attitude and willingness of medical students of the Faculty of Medicine,University of Jaffna,regarding gamete donation.Methods:An institutional-based descriptive cross-sectional study was conducted at the Faculty of Medicine,University of Jaffna,from September 2022 to May 2023 among undergraduate medical students who gave their voluntary participation.A self-administered questionnaire was used as a study instrument to collect data regarding their attitude and willingness toward gamete donation.Results:A total of 345 participants were recruited and their sociodemographic data revealed that 56.8%of the participants were female,62.3%aged between 26 and 30 years,and 92.2%were unmarried.Many of them received information regarding gamete donations during their clinical appointments.Over half(67.8%)of them showed a negative attitude towards gamete donation.Regarding willingness,only 39.7%of participants had a positive approach for being a gamete donor;among them,84.7%preferred anonymous donations.Religion and ethnicity had a significant influence on their attitudes and willingness.In addition,male was also found to be more willing to donate gametes.Conclusions:Most medical students have negative views about gamete donation.Imparting awareness and knowledge of assisted reproductive technology and gamete donation within medical students'sociocultural and ethical backgrounds might facilitate a change in attitude towards gamete donation amongst future medical practitioners.

Human circBOULE RNAs as potential biomarkers for sperm quality and male infertility

Reliable molecular biomarkers to predict fertility remain scarce.The current study investigated the potential of testis-specific circBOULE RNAs as biomarkers for male infertility and sperm quality.Using reverse transcription-PCR and real-time reverse transcription-PCR assays,we identified seven circular RNAs from the human BOULE gene in human sperm.We observed that the expression level of circEx3-6 was significantly reduced in asthenozoospermia,while the expression levels of both circEx2-6 and circEx2-7 were decreased in terato-zoospermia,compared with the controls.Furthermore,we demonstrated that the expression level of circEx2-6 was negatively correlated with the sperm DNA fragmentation index,and the expression level of circEx2-7 was correlated with both fertilization and cleavage rates in those treated with the assisted reproductive technologies.Further functional analyses in a transgenic fly model supported the roles of circBOULE RNAs in sperm development and human male fertility.Collectively,our findings support that sperm circBOULE RNAs may serve as diagnostic biomarkers for assessing sperm motility and DNA quality.Therefore,clinical application and significance of sperm circBOULE RNAs in the assisted reproductive technologies warrant further investigation.

Effect of coenzyme Q10 supplementation on post-vitrification mouse embryo development

Objective:To investigate the effects of coenzyme Q10(CoQ10)supplementation on post-vitrification embryo development and gross morphology.Methods:Balb/c mouse embryos were cultured in potassium simplex optimised medium(KSOM)with varying CoQ10 concentrations[0(control),20,40,and 60μM].The most effective CoQ10 concentration(40μM)was selected for subsequent post-vitrification morphology study.Embryos were randomly divided into four groups:Group A(non-vitrified without CoQ10),Group B(non-vitrified with CoQ10),Group C(vitrified without CoQ10),and Group D(vitrified with CoQ10),followed by vitrification at the 8-cell stage.Survival rates and development until the blastocyst stage were evaluated through morphological examinations using ASEBIR's system,distinguishing normal and abnormal embryos.Results:Supplementation of 40μM CoQ10 significantly increased blastocyst formation(95%)compared to the control group(92%),20μM(62%),and 60μM(56%)(P<0.001).Following vitrification,Group D exhibited a significant increase in blastocyst formation(92%)compared to Group C(82%)(P<0.05).Morphological assessments indicated superior embryo quality in Group B over Group D during the cleavage stage,morula,and blastocyst(P<0.05).Conclusions:CoQ10 supplementation exhibits promising potential to enhance preimplantation embryo development,increase blastocyst formation rates,and improve embryo quality post-vitrification.This offers a promising approach to mitigate oxidative stress on embryos,potentially improving overall assisted reproductive technology outcomes.

Characteristics of Infertile Clientele Attending a Public in Vitro Fertilization Clinic: Appraising Priorities in a Low-Income Country

Introduction: Infertilityaffects one in six couples, and it is an important public health issue largely due to thepervasive effects on the emotional and psychological wellbeing of affected couples. In many developing nations emphasis is placed on childbirth and inability to fulfill this role can be very distressing. There is an unmet need for assisted reproductive technology (ART) in many developing countries and where facilities exist, they are mostly privately owned, expensive and concentrated in urban areas. To bridge this gap, public fertility clinics have been established to provide subsidized care. Evaluating the characteristics and peculiarities of clientele presenting at these public facilities will aid planning and prioritization of care. Methodology: A descriptive retrospective study of 116 infertile patients presenting to the fertility clinic of the University College Hospital, Ibadan, Nigeria from inception on the 14th of February 2019 and 31st of December 2022.Data was analyzed using the Statical Package for Social Sciences (IBM, SPSS, New York) version 23. Descriptive statistics were used to summarize the results which were presented with the aid of bar charts and frequency tables. Result: The mean age of the patients was 40.70 ± 6.62 years. Post-menopausal patients accounted for about one-fifth of the study population while 80.2% (93 women) were older than 35 years. The mean duration of infertility was 9.39 ± 6.11years and nine patients (7.8%) had a duration greater than 2 decades. Secondary infertility occurred in 67.2% of the women. Twenty-nine women (25%) had undergone myomectomy prior to presentation. Hypertension (11.2%) was the most prevalent comorbidity. Nineteen patients (16.4%) had used contraceptives in the past with the male condom (36.8%)being the most preponderant. Sixty-seven patients had experienced pregnancy losses before 28 weeks of gestation while just 16 patients (13.8%) had undergone ART, and none was successful. Conclusion: Secondary infertility was the prevalent type of infertility and may not be unconnected with the low contraceptive usage and high risk of sexually transmitted infection. Late presentation coupled with a large proportion of post-menopausal clientele suggests delayed health-seeking behavior most probably due to the prohibitive cost of ART. The need to streamline services offered in public fertility clinics is paramount in low-income countries grappling with scarce resources. A pragmatic approach will involve the provision of low-cost ART, while enhancing gamete donation programs through the implementation of gamete sharing policies. This will invariably bridge the unmet need and skewed access to ART in developing countries.

IP &Innovation, within the Context of Frontier Technologies;A Matter of Accessibility with “Open” Questions?

Through a series of duly cited, and quoted (“–”), excerpts, originating mostly from two Technology Trends reports, WIPO (2019), WIPO (2021), an attempt to establish a pseudo dialog is proposed, in order to surface a few questions accessible to a larger public of innovators, who may have an interest in the IP accessibility dimension using Frontier Technologies (such as AI, IoT, 3D…). AT, Assistive Technology, is instrumental as a uniquely faceted example. The illustrations’ section extends the consideration and integration of additional “traits” of the field of interest and related. Intuitive answers are “reachable” and further literature is provided on the relevant matters and connected. The emphasis is on educational, illustrative and demonstrative value.

意大利辅助用具免费供给残疾人体系(英文)

Aids are only one of the instruments with which the disabled person can often reach a good level of autonomy,he can improve his conditions of life and prevent the aggravating of his situation. Aids serve also to facilitate care on the part of the family. The rights confirmed by Law 104 can also be achieved through the use of aids. The Italian state has planned a system of care with regards to aids so that some of them can be purchased with different tax concessions but essential aids,those necessary for the reaching of autonomy goals and prevention defined by an individual rehabilitative project,are supplied free of charge. In Italy essential aids are part therefore of a rehabilitation plan that is identified for each person with disabilities by a team made up of different professionals.

AB100.Screening for vision and hearing loss in patients with dementia:recommendations from interviews with sensory experts

Background:Dementia is a syndrome that affects a person’s ability to understand and express information.The higher prevalence of vision and/or hearing losses among persons with dementia in long-term care(LTC)facilities interferes with the ability of nurses to provide optimal care because communication is compromised.Therefore,the detection and screening for sensory impairment is of the utmost importance in LTC facilities;however,there is currently no agreement among nursing professionals on how to best identify such losses for the purpose of further referral,and the need for a validated screening measure suitable for nurses in LTC facilities is clear.The present project aims to close this gap by investigating the screening recommendations of vision-and hearing-care professionals working with clients affected by dementia.Methods:Eleven experts in audiology,optometry,deafblindness,and technology participated in individual semi-structured interviews on the topic of tools and strategies that can be used to screen individuals with dementia for sensory loss.Interview transcripts were coded by two evaluators using verbal agreement and consensus building.Results:Three main themes emerged from the interviews with experts:barriers,facilitators,and strategies.Barriers to sensory screening were often mentioned,particularly impaired communication and lack of staff cooperation.Facilitators consisted uniquely of people,such as family members,intervenors,and nurses.Strategies for sensory screening in this population consisted of improving communication through repetition and encouragements;considerations based on familiarity;and inferring an impairment on the basis of patient behaviour.Few of our interviewees were knowledgeable on the topic of screening apps.Conclusions:Our findings,to be integrated with a similar environmental scan conducted among LTC nurses,can inform the administration of sensory impairment screening tests among a population with dementia in order to optimize care.

AB097.Barriers and facilitators related to the use of optical low vision aids,a scoping review

Background:In recent decades,several studies have been performed in the field of(non-)use of assistive technology devices(ATs)and have found that many variables are likely to be involved in the decision-making process of whether a person with a disability uses or abandons their aids.In low vision rehabilitation,high variability rates and a variety of reasons for non-use of low vision aids has been reported.Determinants of non-use of ATs have previously been categorized into personal factors,ATs factors,environmental factors of the user,and intervention factors.It is probable that some of these factors are also associated with the use of optical low vision aids(OLVAs).Thus,using a framework about adherence with medical interventions,the aim of this scoping review was to explore barriers and facilitators related to OLVAs(non-)use.Methods:Existing guidelines of the scoping review Methods were used to examine and summarize the extent,range,and nature of findings regarding factor categories associated to OLVAs usage.Searches were conducted using the following online databases:Embase,MedLine,and ERIC without limitation on publication dates.A combination of key words and MeSH terms was used based upon the identified core concepts of the research question:(I)low vision;(II)assistive technology;and(III)adherence.A charting form,a flow chart of the study selection process,and a combination of a descriptive numerical analysis and a thematic analysis of 24 studies were performed.Results:The results of this review indicate high variability rates(range:13-50%,M=24%,SD=10%)of people possessing OLVAs but not using them.Most authors do not use a precise definition of“non-use”,and when a definition is provided,the terminology is inconsistent.As expected,the four categories of variables identified are likely to be involved in OLVAs’(non-)use:(I)the largest number of concerns were personal factors.Several aspects regarding personal characteristics were identified,such as demographic,physical,psychological,social-emotional,and occupational factors.Some variables,such as age,diagnosis and visual acuity were reported as contradictorily influencing the OLVAs’usage;(II)ATs factors were associated with quality,appearance,practical aspects of use and the very type of OLVAs;(III)environmental factors referred to social support,physical barriers,expectations of the social environment,presence of a helper,and stigmatization;(IV)finally,intervention factors consisted of taking into account user’s opinions,positive health care experiences,instruction and training,provision processes,delivery periods,and follow-up services.Conclusions:This scoping review provides the preliminary evidence that factors related to OLVAs non-use could be classified into the same four typical categories described in the theory of non-adherence.These results suggest that strategies intended to enhance adherence might be for OLVAs should focus on these four aspects of device use.

AB096.Neurophysiological measures of stigma stereotypes

Background:The perceptions surrounding assistive technology have been shown to be increasingly stigmatizing in older adult populations.This stigmatization can lead individuals to the abandonment of the assistive device.Until now,the methods of identifying or predicting the stigma surrounding assistive technology has mostly been qualitative in nature.Here we present a novel quantitate and qualitative research study that uses neuro-cognitive(psychophysics and EEG)and eye tracking technology,in addition to a new questionnaire to investigate the stigma associated with assistive devices.Therefore,this approach plays a major role in understanding and predicting the neural and physiological correlates associated to stigma.Methods:Thirty-four older adults(>50 years)took part in the study.To determine the psychophysiological predictors of stigma surrounding assistive technologies,we monitored brain activity using EEG,heart rate and eye movements using an eye-tracker while participants viewed a series of images containing either an older or younger individual in different social scenarios(e.g.,talking to doctor,at coffee shop).In each scenario,the individual uses either no assistive device,a low stigmatizing device(e.g.,iPad),or a high stigmatizing device(e.g.,electronic magnifier).Results:Here we present preliminary analysis of the eye movement data.Analysis shows that in comparison to images that contained a low stigmatizing device,in images that contain high stigmatizing devices,the latency to fixate the device is shorter,first fixation duration is longer,and the total number of fixations on the device are higher.The environment that the devices is used in has no effect on eye movement metrics.Conclusions:Although the sample size is small,and based on a healthy older-adult population,these initial observations would indicate that latency to fixate and first fixation duration are predictors of stigma associated with assistive devices.Future research should expand this prediction to those actively using assistive devices,and how the measures predict abandonment over time.

Research progress of artificial psychology and artificial emotion in China

Since the concept of artificial psychology and artificial emotion was first presented, it has become a topic of interest in academic circles and enterprises.
