Insights into Positive Mental Health Amid the COVID-19 Pandemic: Evidence from a Study in Croatia

Objective: The COVID-19 pandemic has raised significant concerns about public health, particularly in terms of mental well-being due to heightened fear and uncertainty. The findings of this study are based on a survey conducted to evaluate the mental health status of the general population in Croatia during the COVID-19 pandemic. Methods: A survey conducted randomly and cross-sectionally included 588 respondents from all 21 counties in Croatia. The survey gathered demographic data and assessed various factors related to pandemic response measures and mental health using the Mental Health Continuum—Short Form (MHC-SF) scale. Results: Despite feeling adequately informed about COVID-19 (76.0%), most respondents (60.8%) expressed concerns about their loved ones during the pandemic. There were significant numbers who felt there was no risk of infection (50.9%) or believed they would not get infected (40.2%), while 72.4% were content with government measures. A statistical analysis indicated that mental health was not significantly different between genders, but age-related differences were evident, with those under 21 experiencing the most distress. The lowest level of psychological and social well-being was observed in respondents who were unemployed. Conclusions: The study identifies vulnerable groups in the Croatian population during the pandemic, including younger individuals, those on parental leave, students, and the unemployed, who exhibited worse mental health. The importance of implementing targeted mental health interventions to support these vulnerable groups is highlighted by these findings.

Increased prevalence of valgus constitutional alignment subtypes in a South African arthritic population group using the coronal plane alignment of the knee (CPAK) classification

BackgroundKnee alignment philosophies and patient specific models to improve patient reported outcomes are gaining increasing attention. The coronal plane alignment of the knee (CPAK) classification describes nine knee phenotypes and then proposes surgical alignment strategies to achieve constitutional alignment. The CPAK classification has been validated in Australian, European, Asian and North American population groups. To date no African data has been analyzed using CPAK. MethodsA total of 344 arthritic patients (608 knees) with appropriate long leg radiographs were classified based on the CPAK type. Measurements included mechanical hip-knee-angle(mHKA), medial proximal tibial angle (mMPTA) and lateral distal femoral angle (mLDFA) and the derived calculations of joint line obliquity (JLO) and arithmetic hip-knee-angle (aHKA). ResultsThe sample population was 77.9% (n = 268) female with a mean age of 68.4 ± 9.2 years. The most common CPAK types in order were type 3 (n = 174; 28.6%), type 2 (n = 155; 25.5%), type 1 (n = 94; 15.5%) and type 6 (n = 80; 13.2%). The most common limb alignment types were valgus (CPAK types 3,6,9; 41.8%). ConclusionThis study, which investigated arthritic patients from a single institution in South Africa, shows a divergence of CPAK phenotypic knee patterns relative to other international studies, with much higher proportions of valgus phenotypes (3 and 6). This regional difference should be further investigated in other South African and African population samples and used to adapt the surgical strategies employed by local surgeons.

Healthcare Professionals’ Perspectives on HPV Recommendations: Themes of Interest to Different Population Groups and Strategies for Approaching Them

As a flagship of the Europe’s Beating Cancer Plan, the European Commission supports EU member states’ efforts to strengthen and expand the routine vaccination of girls and boys against human papillomavirus (HPV). Populations across Europe have grown in diversity, and health systems must adapt to meet the specific needs of increasing diversity. Healthcare professionals (HCPs) must strive to communicate HPV vaccine information in a culturally sensitive manner and address specific concerns related to cultural beliefs, trust in health systems and perceived risks. The objectives of this exploratory study are to identify which themes are most frequently raised during the recommendation of vaccination to minors based on the characteristics of the population (religion, region of origin, gender, level of education and language proficiency) and to collect strategies to improve communication with a diverse population. A survey was distributed through various European public health institutions to HCPs in the region and their networks. The survey included multi-response questions (themes addressed during vaccination recommendation based on population characteristics) and open-ended questions (own qualitative comments and strategies). The most common issues that arise during vaccine recommendation are a lack of knowledge, followed by misinformation. Differences were detected according to the population characteristics. Suggested strategies to improve HPV vaccine recommendation focused on the following aspects: affordability; sexuality and gender; communication platforms; multilingualism; quality of care; school collaboration. HCPs report differences according to the characteristics of the population receiving the recommendation. Personalisation of the recommendations would help to optimise the decision-making process for some groups.

Continuity and Change in the Cult of the Dead: Shaping Kin Formation in the Peruvian Andes (a.d. 1000–1600)

ABSTRACT This paper presents the results of archaeological investigations within funerary contexts at the site of Marcajirca (a.d. 1000–1600) in the north-central highlands of Peru. The results suggest the existence of various population groups, or ayllu members, that were buried at this site. Two contemporary types of tombs are predominant, funerary caves and chullpas, along with two belowground tombs, which are atypical in the region. Bioarchaeological analyses indicate that all the tombs were collective and that the remains were manipulated over time. The evidence from Marcajirca points to important changes in funerary patterns with respect to the previous period, including tombs being incorporated into residential places and, later in time, tombs as created, extra, private spaces by enclosing the chullpas within patios where rituals such as burning of offerings were practiced. The results are discussed within the context of the cult of the dead and the formation of ayllus.

The edutainment program on knowledge, perception, and uptake of cervical cancer screening among Muslim women in Southern Thailand: a quasi experimental study

IntroductionCervical cancer is a significant global health concern and is the third most common cancer in women. Owing to their religious beliefs, Muslim women in Thailand are less likely to be screened for cervical cancer.ObjectiveThis study aimed to explore how a Health Belief Model (HBM) (HBM = Health Belief Model)-Based Edutainment Program affects the knowledge, perception, and uptake of cervical cancer screening among Muslim women in Thailand.MethodsA quasi-experimental study was conducted in two rural districts of Southern Thailand with 83 Muslim women (intervention = 42, control = 41). The assessment was conducted through face-to-face interviews at baseline, post-intervention, and at 3-month follow-up. The intervention included four sessions involving video clips, folk songs, and short films. Data analysis was performed using repeated-measures ANOVA (ANOVA = Analysis of Variance) at a significance level of 0.05.ResultsThere were significant differences in the mean score of knowledge and perception between the intervention and control groups post-intervention and at 3-month follow-up (p < 0.001). The mean scores of knowledge and perception in the intervention group significantly increased post-intervention and at 3-month follow-up (p < 0.001). The uptake of cervical cancer screening tests in the intervention group was approximately twice as high as that in the control group (90.47% vs. 51.21%).ConclusionThe findings revealed that the Edutainment Program could improve the knowledge, perception, and uptake of cervical cancer screening among Muslim women in Thailand. In future studies, the intervention suggests testing different population groups to improve access to primary care for everyone.

Sex estimation from mandibular morphometry using discriminant analysis–CT scan based retrospective study

It is well known that skeletal characteristics vary among different populations. Sex dimorphic characteristics of the mandible have been reported from studies using either mandible bone or computer tomography (CT) scan images of the mandible to test its efficacy in estimating sex. Mandibular studies for estimating sex in any particular population group may not hold well for different populations owing to inherent geographical variations. With this background, we assessed the validity of mandible measurements from CT scan images to determine sex in the South Indian population. As a part of our study, 11 metric parameters and 1 angular parameter were measured and analyzed. The mean values of all the parameters were significantly higher for males as compared to females. Bigonial breadth indicated the best discriminatory ability of the study. Mandibular angle had the least predictive accuracy among all the discriminant functions studied. We further observed that a combination of parameters gave the best overall classification rate (92.3 %). When the same functions were tested on an independent testing data set, a combination of parameters and bigonial breadth gave the best classification rate (82.1 %) which was consistent. We concluded that the mandible has a high accuracy for sex estimation. All the parameters studied demonstrated statistically significant differences between the two sexes except the mandibular angle.

Hydrogeochemical processes, and health risk assessment of groundwater, in Santa María del rio aquifer: A case study of San Luis Potosí valley, Mexico

The main objectives of this research were to the hydrogeochemical processes that control the groundwater chemistry, groundwater quality, and assessment of health risks of water. The drinking water that supplies the community of Santa María del Rio, S.L.P., comes from groundwater, in some municipality localities, groundwater Fluorine and arsenic are reported. Twenty-one representative groundwater samples were taken. Physicochemical parameters in situ: pH, OD, ORP, Alkalinity, STD, EC, Salinity, Total Coliforms, and E-coli, were analyzed, and in the laboratory, the heavy metals, metalloids and major constituents, cations: calcium, sodium, magnesium, and potassium, were determined by the ICP, and anions: chlorides, and sulfates, by colorimetry techniques. The results of the analyses were compared with the Mexican and EPA drinking water standards to verify their suitability and ensure that they do not exceed the permitted limit values. The results of the chemistry of the principal groundwater ions in the study area suggest that the main hydrogeochemical process that controls the variation of groundwater quality is the rock–water interaction. Groundwater has been classified into two hydrochemical facies, CaMgHCO3 and NaHCO3, consistent with the type of rock. The samples with the CaMg–HCO3 facie are associated with less evolved waters located in areas with local recharge. The dominant reactions in the aquifer are calcite, dolomite, and gypsum solutions. The presence of the N–NO3- ion is associated with agricultural and urban zone influence, which indicates that this activity has impacted the water quality. The risk index (HI) results show that values > 0.1 < 1 of HI, for Pb present low chronic risks for adults and children. In contrast, HI values > 4 for both population groups represent high chronic risk. Excessive use of fertilizers should be controlled in the study area to prevent groundwater contamination by heavy metals and metalloids and be measured regularly to check drinking water quality.

The cost of climate change: A generalized cost function approach for incorporating extreme weather exposure into public transit accessibility

Public transit offers urban populations physical accessibility to resources and opportunities. However, at the same time, transit trips often expose users to extreme environmental conditions, such as extreme heat and cold since transit journeys usually include out-of-vehicle trip segments including walking and waiting. Such exposure can be considered as environmental health costs because exposure to weather extremes can lead to adverse health outcomes. Even worse, climate change is increasing the intensity and frequency of extreme weather events. In this context, how can we make public transit accessibility measures ready for climate change? This paper attempts to answer this question by developing a generalized cost function approach combining travel time and environmental health costs into an integrated measure of dual accessibility: a measure of the travel costs of accessing a fixed number of destinations. We synthesize transport science, environmental health, remote sensing, and urban climatology to empower the proposed framework. To demonstrate the utility of the proposed method, we carry out an example study that incorporates transit passengers' extreme cold exposure into accessibility measures in the city of Winnipeg, Manitoba, Canada. Further, we perform a social equity analysis to investigate whether the increase in total integrated costs (i.e., decrease in accessibility) due to the inclusion of environmental health costs disproportionately affects socially disadvantaged population groups. The proposed method enables a more realistic and practical measurement of public transit accessibility under climate change; thereby, improving the readiness and resilience of our society and transport systems for future challenges.

Exploring constraints to leisure participation within the countryside

ABSTRACT The health and well-being benefits of accessing occupations in natural outdoor environments are well evidenced. However, not everyone has access to these spaces and constraints to leisure participation within rural spaces have been relatively unexplored. This study explored the everyday lives of participants of the Mass Observation Project archive to identify constraints to occupational participation within the countryside in the United Kingdom. Thematic analysis was used to interpret data from two collections; one that focused on ‘The Countryside’ (Winter 2013) and another on ‘Identity and Environment’ within ‘Loneliness and Belonging’ (Spring 2019). The study found that social norms, infrastructure, health issues, personal preferences, and a lack of shared experiences all affected participation in occupations. These constraints often corresponded with a disengagement from desired occupational participation. Findings have implications for occupational science in relation to understanding constraints to meaningful participation. There is need for further research around the impact of belonging and meaning on occupational participation and engagement within rural spaces within diverse population groups, particularly in terms of age, socioeconomic resources, and ethnicity.

Cannabinoid residuals in tissues of lambs fed spent hemp biomass and consumer's exposure assessment

Spent hemp biomass (SHB) contains trace amounts of cannabinoids, including Δ9-tetrahydrocannabinol (Δ9-THC), that may accumulate in the tissues of animals consuming SHB. We measured cannabinoid residues in the liver, adipose tissue, and muscle of finishing lambs fed either 10% or 20% SHB for 8 weeks, or 4 weeks followed by 4 weeks SHB withdrawal. We detected multiple cannabinoids in the liver at a similar proportion to the SHB. However, CBD and Δ9-THC were enriched >20-fold in the adipose and muscle, compared to their proportion in SHB. The highest concentration of Δ9-THC was detected in adipose tissue and was 7.4-times higher than in muscle. Most cannabinoids were undetectable in tissues after 4 weeks of clearance. The consumers’ exposure assessment on Δ9-THC revealed tissue levels of total THC (THCA+Δ9-THC) that exceed the acute reference dose of 1 μg/kg BW across population groups. When consuming meat from the lambs fed 10% and 20% SHB, the maximum total THC exposure was 2.03 and 7.32 μg/kg BW, respectively, equal to or below the Lowest Observed Adverse Effect Level of 36 μg/kg BW, the No Observed Adverse Effect Level of 12 μg/kg BW or a tolerable dose intake of 7 μg/kg BW.

The Evolution of Science and Regulation of Dietary Supplements: Past, Present, and Future

Dietary supplement use in the United States is widespread and increasing, especially among certain population groups, such as older Americans. The science surrounding dietary supplements has evolved substantially over the last few decades since their formal regulation in 1994. Much has been learned about the mechanisms of action of many dietary supplement ingredients, but the evidence on their health effects is still building. As is true of much nutrition research, there are many studies that point to health effects, but not all are at the level of scientific evidence (e.g., randomized controlled interventions), rigor, or quality needed for definitive statements of efficacy regarding clinical endpoints. New technologies and approaches are being applied to the science of dietary supplements, including nutrigenomics and microbiome analysis, data science, artificial intelligence, and machine learning – all of which can elevate the science behind dietary supplements. Products can contain an array of bioactive compounds derived from foods as well as from medicinal plants, which creates enormous challenges in data collection and management. Clinical applications, particularly those aimed at providing personalized nutrition options for patients, have become more sophisticated as dietary supplements are incorporated increasingly into clinical practice and self-care. The goals of this paper are to provide historical context for the regulation and science of dietary supplements, identify research resources, and suggest some future directions for science in this field.

Experiences of Consumers on the Health Effects of Fake and Adulterated Medicines in Nigeria

Medicines are used to cure and treat ailments, relieve or eliminate disease symptoms, and slow down the disease process. Any attempt to disrupt this natural medicine process, using falsified medications, spells doom to a consumer of such medication. The challenge of fake medicines is a global one and affects developing and developed nations and currently assumes great significance as a result of globalization challenges, which have flattened the entire world, hence removing barriers to the movement of products and services. The cross-sectional survey was conducted, using six local government areas of Anambra State in South-East Nigeria, namely Awka, Nnewi, Onitsha, Aguata, Ogbaru, and Anaocha, among adults aged 18 years and above. A minimum sample size of 500 was calculated and stratified sampling was employed to select respondents in order to ensure that various population groups, the upper class, middle class, and lower class were represented. This research has shown that falsified medicine is an evil wind that blows nobody any good. It negatively affects every aspect of the citizen’s livelihood, ranging from their health, which manifests as treatment failures, deformities, loss of life to death, to loss of confidence in the healthcare providers, revenue losses to individuals, healthcare providers, manufacturers, and finally corruption of the genuine medicines supply chain with fake and adulterated medicines. The study has clearly shown the experiences of residents of Anambra State, South-East Nigeria with fake and adulterated medicines and also services as a wake-up call to medicines regulators like NAFDAC, PCN, the PSN, and Federal Ministry of Health to declare a state of emergency on the fight against fake and adulterated medicines and make enabling laws that are punitive enough towards the fight against this scourge, so that the healthcare and well-being of Nigerians would be assured at all times.

Phenotypic analysis of mezcal agaves from the Central Valleys of Oaxaca

Objective: Mezcal agaves in the state of Oaxaca have a high economic value due to the demand for mezcal production; therefore, the purpose of this work was to assess and highlight the importance of morphological diversity within and among cultivated Agave species. Design/Methodology/Approach: A completely randomized experimental design with 25 treatments (populations) and 11 replicates (individuals) was implemented. The plant (individual) was the experimental unit and 19 morphological descriptors proposed by the National Seed Inspection and Certification Service (SNICS) were assessed. A total of 275 individuals of the Agave angustifolia, Agave karwinskii, Agave marmorata, Agave rhodacantha, Agave potatorum, Agave seemanniana, and Agave nussaviorum species were assessed using a multivariate analysis to determine their phenotypic variability and existing relationships. Results: The dendrograms for the Q-mode and R-mode were obtained by means of a cluster analysis, forming 4 groups based on the average linkage generated from the standardized BDM of the sampled species of the genus Agave. Four groups were formed using the k-means clustering method, in accordance with field observations and a review of the taxonomic bibliography. The first two principal components (PC) accounted for 66.4% of the total variation, according to the principal component analysis (PCA). For PC1 and PC2, the variables with the highest contribution were those related to leaf shape (Fh), size of the lateral spine (FEL), number of leaves (Nh), plant height (H), uniformity in the size of the lateral spines (UTE), and terminal spine shape (FET). Study Limitations/Implications: A comprehensive study requires taxonomic keys to identify species, subspecies, and even varieties of Agave. Additionally, molecular characterization is essential to understand the variability and phylogenetic relationships of these populations, subject to a phylogenetic analysis. Findings/Conclusions: Multivariate analysis techniques revealed that three species showed high phenotypic variability in the maturation stage under cultivation conditions. The A. potatorum and A. karwinskii species had a greater intra-population phenotypic variability, with significant differences within the same species. Agave marmorata showed no intra- or inter-population variability. Leaf texture (Txh) was the only variable that explained the variation within its group. This is a tall species whose diameter is larger than in the other species. The variables of the Mexican (Agave rhodacantha) group showed low correlation, as their behavior was highly dispersed. The variables obtained in the field from this group of populations must be meticulously assessed to identify the degree of correlation between the variables and to confirm the behavior of this group.

Prevention and correction of micronutrient deficiencies. What do we know about it?

BACKGROUND: Micronutrient deficiencies, including deficiencies of vitamins and microelements, are a major public health concern worldwide. They are highly prevalent, particularly in developing countries, and have significant health consequences, including anemia, impaired immune function, cognitive impairment, and growth retardation. Micronutrient deficiencies can also contribute to the development of chronic diseases, such as cardiovascular disease and diabetes. Micronutrient deficiencies can also contribute to the development of chronic diseases. AIM: To study the knowledge, interest and motivation of different population groups regarding vitamin and micronutrient intake. MATERIALS AND METHODS: The original questionnaire with 45 questions was completed by 344 respondents: 141 (41%) without medical education, 91 (25.4%) with higher medical education, 112 (32.6%) by students of medical unvesities. RESULTS: Only 100 (29.4%) respondents considered their nutrition balanced. 180 (52.3%) people did not consume vegetables and fruits on a daily basis, 82 (23.3%) respondents almost never consumed fish and seafood. Almost all respondents [335 (97.4%)] took some vitamin and mineral complex at least in one of the periods of their life, 284 (82.6%) — did it without a doctor’s prescription. Female respondents demonstrated a higher level of knowledge about the problem under study: 115 (41.9%) women and only 17 (24.2%) men had checked vitamin D levels (p = 0.006), while 187 (68.2%) women and only 33 (47.1%) men had taken vitamin D (p = 0.006). Those receiving/having higher medical education were more likely to take vitamin D (4.4 times), vitamin B6 (3.8 times), selenium (3 times), and zinc (2.8 times) than non-medical respondents. CONCLUSIONS: The nature of nutrition indicates potential risks of micronutrient imbalance in the respondents. Knowledge about the problem of micronutrient imbalances among the study participants is not systematized. Men and people without medical education have less knowledge on this topic and are less likely to take various micronutrients.

P-716 What do Africans know about their fertility? A systematic literature review exploring fertility knowledge, attitudes, and behaviour among African population groups

Abstract Study question What is the knowledge, attitude, and behaviour regarding fertility, among African population groups? Summary answer Fertility knowledge and uptake of treatment options for infertility were found to be sub-optimal while the attitude towards fertility were mixed. What is known already Infertility affects 1 in 6 couples worldwide according to the WHO, with some evidence of higher incidence among the African population. Health policies have highlighted the importance of optimising fertility through better knowledge and, recently, there has been a concerted effort from several stakeholders to improve fertility-education. An important component of doing this effectively is to understand the current status and identify gaps. Most studies on this topic, however, have focused on high-income countries. This study aimed to assess current patterns of fertility knowledge, attitudes, and behaviour; and identify improvement opportunities but with a focus on the African population group. Study design, size, duration Global Health, MEDLINE, Web of Science PubMed, Scopus, and Google scholar databases were systematically searched for articles published between 2000 and 2023. Articles covering fertility knowledge, attitude and practices were included if they had been conducted in Africa and were published in an English language peer-reviewed journal. Participants/materials, setting, methods Articles were extracted and reviewed independently by two researchers. Content was analysed and categorised thematically. Quality assessment of studies were conducted. Main results and the role of chance The systematic search yielded 1939 articles and 25 articles were included, studies were from Nigeria, South Africa, Gambia, Egypt, Kenya. Overall, the reviewed studies showed that Africans place a high value on their fertility and have high aspirations towards parenthood, with childbearing being perceived as fulfilment or destiny. Knowledge and understanding of ART and treatment options was found to be low in studies assessed. There was also low knowledge of age-related fertility decline and low understanding of the menstrual cycle and ovulation. Although the attitude towards infertility and assisted reproductive technology was mixed, there is more openness within the higher-socioeconomic demographics, although generally sub-optimal. Overall studies also highlighted several myths and misinformation about ART. There were important factors influencing behaviour: such as the importance of being married, having a steady income, and safe-housing. Some studies also highlighted that cultural beliefs and religion also play an important role. Research findings showed that there is stigma associated with childlessness in many African communities. Although some studies reported attributing infertility to fate or destiny, most remain open to treatment through various methods, ranging from ART to herbalist and spiritual intervention, with some considering prayer a method of treatment. Limitations, reasons for caution This study focused on fertility knowledge, attitude and practices of Africans which has implications for generalisability among wider population groups. From our quality assessment, some of the studies in the systematic review had methodological limitations. Wider implications of the findings While strategies and policies to improve fertility awareness are being deployed, it is important to consider the needs of lower- and middle-income countries. Findings can inform government policies aiming to improve education, minimise ART costs, improve health-equity and access; ultimately allowing people to achieve their desired family-building intentions.

O-019 Outcomes and correlations between traditional Intracytoplasmic Sperm Injection (ICSI) method and a new AI-enhanced system

Abstract Study question In the context of ICSI, how does the Sperm Tracer Deep Neural Network analysis compare to the embryologist’s sperm selection technique? Summary answer Sperm Tracer AI system significantly improves fertilization rates, offering a standardized, objective approach to sperm selection, but nuanced correlations highlight complexities in sperm parameters. What is known already Traditional sperm selection during ICSI relies on subjective, manual methods, introducing variability and affecting pregnancy success. In response, AI applications, aim to enhance objectivity, potentially improving pregnancy rates. Study design, size, duration Between September and December 2023, the study examined 26 fresh ICSI cycles in a total of 268 sibling oocytes. Men aged 18 years and above with 34.4 mean women’s age. The Sperm Tracer group underwent single embryo culture, while the Embryologists' group underwent group embryo culture. The study analyzes statistical differences in fertilization rates, day 3 and day 5 embryo development. The study duration aligns with the analyzed cycles. Participants/materials, setting, methods The study compared real-time AI-assisted sperm evaluation with the Sperm Tracer system to the traditional ICSI method by embryologists. Correlation analysis was performed for the following kinematic parameters: Amplitude of Lateral Head displacement (ALH), Dance (DNC), Linearity (LIN), Straightness (STR), Wobble (WOB), Curvilinear Velocity (VCL), Linear Velocity (VSL) and Average Path Velocity (VAP). Statistical analysis involved Odds Ratios (OR) with 95% confidence intervals, Mann-Whitney U tests and correlation analyses by Pearson’s coefficient. Main results and the role of chance The Sperm Tracer system exhibited a noteworthy enhancement in fertilization rates (OR: 0.46, 95% Confidence Intervals (CI) [0.23, 0.89], p = 0.0224) but no significant differences in cleavage stages, blastocyst formation, or the production of good-quality embryos compared to conventional methods. For correlation analysis used two groups of sperm population. Group A comprises spermatozoa subjected to ICSI with the Sperm Tracer system, resulting in unsuccessful oocyte fertilization and Group B consists of spermatozoa that achieved successful fertilization. In Group A, correlation analysis identified significant negative associations between DNC and linear parameters (LIN, STR, WOB) (p &amp;lt; 0.001), highlighting the clinical relevance in sperm motility. Group B displayed a distinct negative correlation between DNC and LIN (p = 0.03941), indicating potential effects on sperm linear velocity. LIN in Group A exhibited strong negative correlations with WOB (p = 0.0001), moderate negative correlations with STR (p = 0.0028), and VCL (p = 0.0773). Moreover, ALH analysis in Group A unveiled robust negative correlations with LIN, STR, and WOB, suggesting clinical significance in sperm motility. These intricate findings underscore the Sperm Tracer system's primary advantage in optimizing fertilization rates, offering valuable insights for refining sperm selection strategies in assisted reproduction. Limitations, reasons for caution The study faces limitations due to a small sample, impacting generalizability. Divergence in culture embryo strategies introduces bias, necessitating validation in larger studies. The system includes morphology analysis, but no data analysis has been conducted. Exploring the correlation between morphology, considering embryo culture variations, and motility could provide valuable insights. Wider implications of the findings This study highlights AI applications like Sperm Tracer, showcasing their potential to improve assisted reproduction outcomes. Recognizing AI's impact on IVF success is vital for adoption. Integrating AI into clinic protocols may boost IVF efficiency, requiring training for embryologists to ensure effective utilization.

P-737 Congenital tubal anomalies: exploring its relationship with tubal factor infertility: observational-descriptive study

Abstract Study question Is there any relation between congenital Fallopian tube anomalies and tubal factor infertility in subset of infertile women? Summary answer Nearly 15% of women who underwent diagnostic laparoscopy revealed congential tubal anomaly (15%), including total or partial agenesis of tubes. What is known already The fallopian tubes play a crucial role in the reproductive process. These structures are 10-12 cm in length, consists of four parts from proximal to distal side: intramural, isthmic, ampullary and fimbrial [1]. Any abnormalities in their development or structure can severely affect fertility. Fallopian tube agenesis, whether partial or complete, constitutes one such anomaly. While there have been numerous advances in the understanding and management of fallopian tube disorders, partial or complete fallopian tube agenesis remains an enigmatic entity with unknown prevalance in the general population. Study design, size, duration Observational study was conducted between 2020 and 2023. All couples with primary infertility were evaluated in an outpatient clinic using basic hormone analysis, semen analysis, sonography and hysterosalpingogram as a standard of care. All women with suspected tubal pathology were offered to have diagnostic laparoscopy (LS) in order to confirm the anomaly. When tubal and/or Mullerian anomalies were detected, urinary system was examined by intravenous pyelography. Other suspected pathologies were examined by abdominopelvic CT x-ray. Participants/materials, setting, methods All women with suspected tubal pathology were offered to have diagnostic laparoscopy in order to confirm the anomaly. Surgeries was performed by two experienced surgeons, after having informed consent. When tubal and/or Mullerian anomalies were detected, urinary system was examined by intravenous pyelography. Other suspected pathologies were examined by abdominopelvic CT x-ray imaging. All anomalies have been reported in an electronic database. Main results and the role of chance A total of 4230 infertile couples were admitted to clinics. Mean age of women in the study population is 30±2.3 years. Overall duration of infertility is 1.2±0.6 years. Among them, 895 women were diagnosed to have suspected tubal pathology after HSG examination (21%). Diagnostic LS was performed to 220 women. Flowchart of the patients is given in figure-1. Among them, 113 (51,3%) women revealed tubal pathologies/anomalies and 107 (49,7%) revealed normal findings. Total of 34 women revealed congenital proximal and/or distal tubal anomaly. Half of these cases (17/34) were complete agenesis and remaning were either with proximal or mid-distal portion agenesis. Majority of women 32/34 (94 %) with tubal pathology revealed at least 1 uterine anomaly as well. Among them, 19 (55.9 %) of these patients was confirmed to have unicornuate uterus, 6 (17.6 %) had uterus didelphys, 4 (11.8 %) had bicornuate uterus, and 3 (8.8%) had uterine septum. No uterine anomaly was observed in 2 (5.9 %) patients. Total of 16 women (14%) were diagnosed to have other system anomalies. Limitations, reasons for caution Lack of a control group in normal population in order to compare incidences. Secondly, our sample size is not enough to precisely conclude on exact prevalances. Third, we did not report fertility data following LS. Wider implications of the findings Tubal factor infertility is one of the major etiologic factor among primary infertility cases and congenital tubal anomalies were reported to be relatively higher (15%) in these younger women contrary to general expectations. Second important finding is high congenital uterine anomaly incidence in women with congenital tubal anomalies. Trial registration number not applicable

Dual Infection of Different Clusters of HIV in People Living with HIV Worldwide: A Meta-Analysis Based on Next-Generation Sequencing Studies.

To understand the global dual HIV infection (DI) profiles comprehensively, the databases Cochrane Library, Embase, PubMed, and Web of Science were the data sources up to March 31, 2024 (PROSPERO: CRD42023388328). Stata and R-language software were used to analyze the extracted data. Publication bias was assessed using Egger's test. Sensitivity analysis was conducted to evaluate the stability of the combined effect values. Data from 17 eligible studies across four continents (Africa, Asia, Europe, and North America) with 1,475 subjects were used. The combined dual infection rate (DIR) was 10.47% (95% CI: 7.11%-14.38%) without a time trend (p = 0.105). The DIRs of target population groups differed significantly, with FSWs having the highest DIR (15.14%), followed by general population (12.08%), MSM (11.84%), and DUs (9.76%). The subtype profiles of 122 patients with dual infection were extracted, and the results showed that intrasubtype infections were predominant in coinfection (16/22, 72.73%) and superinfection (68/100, 68.00%) groups, with the subtype pattern B and B accounts for the largest proportion. The global dual infection rate may be underestimated, even though the data fluctuated around 10% and showed no time trend. The occurrence of DI indicated that individuals still do not acquire sufficient resistance to HIV even after primary infection, which could potentially compromise the patient's treatment effect and lead to the emergence of new subtypes, posing a significant challenge to HIV prevention, control, and treatment, suggesting that behavioral counseling and health education for all HIV-infected individuals are still crucial during the antiviral therapy.

Evaluation of Thyroid functions in Patients with End Stage Renal Disease in a Sample of Egyptian Populations

Abstract Background In most cases, hypothyroidism is not linked to kidney disease. However, hypothyroidism has been shown to hasten the development of chronic kidney disease (CKD). Aim of the Work to evaluate thyroid abnormalities in patients with end stage renal disease in a sample of Egyptian populations. Patients and Methods This study was conducted with 70 Egyptian Patients selected from Nephrology department in Theodor Bilharz Research Institute, in a case control study, they were categorized into 2 groups Group 1: Stage V renal disease group (n = 40): patients with eGFR &amp;lt;15 mL/min with no history of thyroid disease or receiving any thyroid medications. Group 2: Age and sex matched health population group (n = 30): with normal renal function with no history of thyroid disease or receiving any thyroid medications. All subjects underwent full thyroid profile, and estimated GFR. Results Symptoms of thyroid dysfunction were more frequent in end stage group, the difference statistically were significant only in muscle weakness. TSH was statistically significantly higher in cases with hypothyroidism. TGABs were statistically significantly higher in cases with hypothyroidism. Antimicrosomal antibodies recorded only in hypothyroid cases, the differences were statistically significant. FT3, TSH, TGABs and thyroid volume statistically had perfect diagnostic performance in diagnosing hypothyroidism among end stage renal disease group. Conclusion Frequency of hypothyroidism was higher in end stage renal disease patients compared to control group. So, it is important to keep monitoring thyroid functions in patients with advanced renal impairment that may enhance quality of life.
