The Impact of Rising House Prices on Young People’s Fertility

At present, the problems of population aging and low fertility of young people in China have become more and more serious, which has become an important factor restricting economic and social development. Although the “comprehensive” policy has been implemented and has achieved certain effects, the willingness of young people to give birth is still low. At the same time, the rise of housing prices has become one of the major social and livelihood issues, and the impact of housing prices on people’s fertility intentions has also received widespread attention from scholars at home and abroad. Based on this, this study takes young people of childbearing age in China as the research object, adopts the research method to study the impact of rising housing prices on the fertility behaviour of young people in the city, and based on the conclusions drawn, puts forward targeted suggestions for the benign development of the real estate market and the effective implementation of the population policy.

Hepatitis co-infection in paediatric HIV: progressing treatment and prevention.

To analyse the main evidence and recommendations for the management of hepatitis co-infection in children living with HIV. We analysed available data pertaining to the natural history of liver disease and treatment of co-infected children. Viral hepatitis co-infection in people living with HIV (PLHIV) is a global problem owing to the shared routes of transmission, particularly in areas of high endemicity for the three viruses. Viral hepatitis co-infection can accelerate liver disease progression and increase morbidity and mortality, even in patients on suppressive antiretroviral treatment (ART). Viral hepatitis should be routinely screened in PLHIV and, once diagnosed with viral hepatitis, PLHIV should be closely monitored for liver disease progression and complications. Children living with HIV-HBV co-infection should be treated with ART containing agents which are active against both viruses. Children living with HIV-HCV co-infection should receive directly acting antivirals (DAA) to eradicate HCV infection. Prevention measures to reduce vertical and horizontal transmission of HBV and HCV (anti-HBV vaccination and immunoglobulins, anti-HBV treatment in pregnancy, anti-HCV DAAs in people of childbearing age, avoiding blood contact, sexual barrier precautions) should be adopted and encouraged, particularly in high endemicity countries.

Reproductive Strategies for Declining Fertility: Fertility Preservation

There is a global trend of declining fertility among people of childbearing age and mankind is confronted with great challenges of fertility problems. As a result, fertility preservation technology has emerged. Fertility preservation involves interventions and procedures aimed at preserving the patients' chances of having children when their fertility may have been impaired by their medical conditions or the treatments thereof, for example, chemotherapy and/or radiotherapy for cancer. The changes in patients' fertility can be temporary or permanent damage. Fertility preservation can help people diagnosed with cancer or other non-malignant diseases. More and more fertility preservation methods are being used to preserve the fertility of cancer patients and protect their reproductive organs from gonadotoxicity. Fertility preservation may be appropriate for young patients with early-stage cancers and good prognosis before they undergo treatments (chemotherapy and/or radiotherapy) that can negatively affect their fertility. It is also appropriate for patients with chronic conditions or those who have encountered environmental exposures that affect their gonadal function. Fertility preservation methods include oocyte cryopreservation, embryo cryopreservation, and ovarian tissue cryopreservation (OTC) for women and sperm freezing and testicular tissue freezing for men. The survival rates of children and adolescents diagnosed with malignant tumors have been steadily increasing as a result of advances in cancer treatments. Cryopreservation of oocytes and sperm is recognized as a well-established and successful strategy for fertility preservation in pubertal patients. OTC is the sole option for prepubertal girls. On the other hand, cryopreservation of immature testicular tissue remains the only alternative for prepubertal boys, but the technology is still in the experimental stage. A review showed that the utilization rate of cryopreserved semen ranged from 2.6% to 21.5%. In the case of cryopreserved female reproductive materials, the utilization rate ranged from 3.1% to 8.7% for oocytes, approximately from 9% to 22.4% for embryos, and from 6.9% to 30.3% for ovarian tissue. When patients have needs for fertility treatment, cryopreserved vitrified oocytes are resuscitated and in vitro fertilization-embryo transfer (IVF-ET) was performed to help patients accomplish their reproductive objectives, with the live birth rate (LBR) being 32%. On the other hand, when cryopreserved embryos are resuscitated and transferred, the LBR was 41%. OTC has the advantage of restoring natural fertility and presents a LBR of 33%, compared with the LBR of 19% among 266 IVF patients. In addition, OTC has the benefit of restoring the endocrine function. It has been observed that the shortest recovery time of the first menstruation after transplantation was 3.9 months, and the recovery rate of ovarian function reached 100%. To date, a growing number of cancer survivors and patients with other diseases are benefiting from fertility preservation measures. In the face of declining human fertility, fertility preservation provides a new approach to human reproduction. Fertility preservation should be applied in line with the ethical principles so as to fully protect the rights and interests of patients and their offsprings.

Study on The Influence of High Housing Price on Fertility Desire

In recent years, China's birth rate has been declining continuously, facing the challenge brought by population structure transformation. Nowadays, housing prices in cities are rising rapidly, while the cost of raising children is also very high, and the two important decisions of childbearing age people, housing and reproduction, occupy a lot of family resources. Therefore, this paper explores the impact of high housing prices on fertility desire and finds that high housing prices will have a negative impact on it. That is to say, high housing prices will "squeeze out" fertility desire. Based on this, this paper puts forward three suggestions: First, adhere to the principle of "houses are for living in and not for speculative investment" to improve residents' living space. Second, we will introduce measures to reduce the cost of childbirth and parenting to reduce the burden of childbirth. The third is to create a good social environment to stimulate the birth rate.

Screening for thalassemia carriers among the Han population of childbearing age in Southwestern of China.

Thalassemia is a severe hereditary blood disorder that poses a significant threat to human health and leads to mortality and disability. It is one of the most prevalent monogenic diseases worldwide. The aim of this study was to analyze the molecular epidemiological data of individuals of childbearing age from the Han ethnic group with thalassemia in Southwest China and to explore the application of next-generation sequencing (NGS) technology in screening thalassemia carriers. The participants were Han males and females of childbearing age who sought medical advice at the West China Second University Hospital, Sichuan University from June 2022 to June 2023. We detected α- and β-thalassemia mutations using full-length capture of the thalassemia genes and NGS technology. In a cohort of 1,093 participants, 130 thalassemia carriers were identified, with an overall detection rate of 11.89% (130/1,093). Among these, 0.91% (10/1,093) had mutations that could not be detected using traditional PCR techniques. The proportions of carriers with α-, β-, and α-complexed β-thalassemia gene mutations were 7.68% (84/1,093), 3.93% (43/1,093), and 0.27% (3/1,093), respectively. We identified a novel HBA2 c.166del variant that has not been previously reported. Using NGS technology, we found that the mutation-carrying rate of thalassemia genes was 11.89% in the Han population of childbearing age in Southwest China. Compared with the results of traditional PCR techniques, NGS detected an additional 0.91% (10/1,093) rare genetic variants. NGS technology should be utilized as the primary screening method for thalassemia carriers among Han nationality people of childbearing age in Southwest China.

Abortion in The United States – The Impact of Changing Legislation on Prescription Patterns in Pediatric and Maternal Populations

Background and Hypothesis: Changes in healthcare legislation may have unintended consequences for patient care at the individual level. Following the Supreme Court case Dobbs vs Jackson Women’s Health Organization in 2022 resulting in the reversal of Roe V. Wade, many states enacted new abortion legislation. Currently, there are many restrictions and barriers to abortion and reproductive care that may limit access across the country. Given the volatile political environment surrounding abortion legislation, there may be some confusion among clinicians about the legality of abortion and miscarriage care. Abortion legislation and restriction may have an impact on other areas of healthcare, including prescription patterns of Category X medications in women of childbearing age. Based on the current legislation, we hypothesize that prescription rates of Category X medications will decrease while prescription rates of birth control methods will increase.
 Project Methods: Real world data on prescribing patterns will be obtained from IUH Cerner database and the Cerner Learning Health Network. Demographic information including age, race and insurance status will be obtained. Data will be analyzed to assess trends in prescription patterns for women of childbearing age that correlate with dates of changing abortion legislation.
 Potential Impact: The findings from this study will help direct future research on medication prescription and administration in people of childbearing age. Results may also inform future policy changes surrounding women’s healthcare.

The Fertility Intentions of Highly Educated Young People of Childbearing Age in China

Educational attainment has been recognized by a wide range of scholars as being significantly related to fertility intentions, which gradually decline as educational attainment rises. In this study, we analyzed the factors affecting the fertility intentions of 401 highly educated young people of childbearing age aged 22-30 with bachelor's degree or above in China through a questionnaire survey and interviews with a random sample of young people of childbearing age with bachelor's degree or above in China. The results show that: fertility intention is significantly correlated with all the factors in this study, and can show a certain upward trend influenced by the current economic conditions, the reduction of damage to childbearing, government welfare policies, partner's willingness and support, and the impact on life and career. The study shows that traditional attitudes and other people's willingness have a lower impact on the highly educated people. Improving the level of available medical technology, reducing the risk of fertility among highly educated young people of childbearing age, increasing partner approval and support, and strengthening the supporting measures for fertility packages are the keys to increasing fertility intentions.

Economic and Social Implications of Negative Population Growth

With the rapid development of China’s socioeconomic status, the increasing life quality, and the changing attitudes on marriage and childbearing among people of childbearing age, China has entered an era of negative population growth since 2022. Although China has introduced various policies to encourage births since 2013, the number of births has not increased as expected, but has declined rapidly. Looking back at the historical trend of population change in some developed countries, population decline is an “inevitable” process that many countries have to go through in the process of social and economic development. For China, after more than 30 years of its one-child policy, its population situation has some unique features. Although the willingness of young couples to have children is declining and the number of births is decreasing, there are significant problems such as advanced pregnancy, infertility, and childbearing after caesarean section, which in turn pose a threat to the health of mothers and children and lead to heavy medical burdens. Therefore, how to improve the treatment effectiveness and safety of infertility, the quality of maternal and child health care and the ability to treat high-risk maternal and foetal complications are major issues that China’s maternal and child health care system has to face and deal with urgently.

Reproductive psychiatric advance directives: promoting autonomy for perinatal people with serious mental illness diagnoses.

People with serious mental illness (SMI) diagnoses who become pregnant are particularly vulnerable to symptom recurrence and resulting potential lack of decision-making capacity (Taylor et al. J Psychiatr Res 104:100-107, 2018; Bagadia et al. Int J Soc Psychiatry 66:792-798, 2020). In these situations, prenataland behavioral health providers have little legally viable guidance on what medical and/or psychiatric care the patient desires (Aneja and Arora Indian J Med Ethics V:133-139, 2020). We created a "Reproductive Psychiatric Advance Directive (PAD)," grounded in Reproductive Justice principles, that promotes patient autonomy by proactively articulating perinatal medical and psychiatric care preferences. We conducted a medical and legal literature review using two sets of terms related to (1) PADs and (2) reproductive health. We convened an expert working group of legal, medical, psychiatric, peer, and advocacy leaders and community-based organizations to develop a Reproductive PAD. Our literature review yielded no results about Reproductive PADs. We created de novo a Reproductive PAD template with sections on medical and psychiatric history, informed consent for critical medical and psychiatric care, family planning and custody preferences, and optional sections on abortion and on electroconvulsive therapy. The Reproductive PAD provides a possible legal mechanism for people of childbearing age with SMI diagnoses to articulate their medical and psychiatric care choices around reproduction and pregnancy. Future research should evaluate the Reproductive PAD as an effective tool for protecting patient autonomy during pregnancy and postpartum and guiding medical and psychiatric providers.

5 Translating developmental neurotoxicity for the public: A large, international, randomized-control trial investigating children's environmental health literacy

Objective:Exposure to toxic chemicals during early brain development increases the risk of neurodevelopmental problems in children. Parents' and prospective parents' understanding of the impact of toxic chemicals on brain development and the efficacy of translation tools for children's environmental health literacy are poorly understood. We developed and validated a questionnaire, PRevention of Toxic chemicals in the Environment for Children Tool (PRoTECT) to assess knowledge of toxic chemicals and neurodevelopment, intentions to reduce exposures to toxic chemicals, and preferences for actions by government and industry to prevent neurodevelopmental disorders. Using PRoTECT, we surveyed people of child-bearing age across five countries (Canada, United States (US), United Kingdom (UK), India, and Australia) to identify general patterns of responses on this questionnaire by demographic characteristics, including country, age, gender, parental status, pregnancy status, and education. We also employed a randomized control design to examine the efficacy of a knowledge translation video to instill knowledge and prompt behavioral changes to reduce exposures to toxic chemicals immediately following its presentation and after a six-week follow-up period.Participants and Methods:We recruited 15,594 participants, ages 18 to 45, via CloudResearch's Prime Panels between October-December 2021. After completing the PRoTECT survey, participants were randomly assigned to watch the video Little Things Matter: Impact of Toxic Chemicals on Brain Development (i.e., the experimental group) or to serve as the control group. Next, both groups answered a series of questions to assess their knowledge of toxic chemicals, their intentions to reduce exposures to toxic chemicals, and barriers to changing their behaviours. After six-weeks, we recontacted a subset (N=4,842) of participants to repeat PRoTECT and answer the same series of behavioural questions assessing whether they modified any of their behaviours to reduce exposure and why or why not.Results:Most participants (i.e., 75-85%) agreed that toxic chemicals can impact brain development and endorsed preferences (∼85%) for allocating more resources to prevent neurodevelopmental disorders, especially people with higher education, parents and pregnant women, and people who lived in India. Despite this, a large proportion of participants (∼50%) trusted industry and believed that government effectively regulated toxic chemicals. After the six-week follow-up, experimental participants showed greater changes in scores on PRoTECT (i.e., between 5-15% change), indicating greater knowledge about harms posed by toxic chemicals, more intentions to reduce exposure, and stronger preferences for prevention as compared to the control group. Differences were larger among people from the US, those who were more highly educated, and people in their thirties. However, the differences between groups in making behavioural changes to reduce exposures were attenuated at the six-week follow up as compared to baseline. Significant barriers to reduce exposure to toxic chemicals were reported by both groups and included cost, inconvenience, and not knowing how to determine whether a product is non-toxic or where to purchase non-toxic products.Conclusions:We observed greater knowledge and concerns about toxic chemicals among more affluent respondents, pregnant women and parents, and people living in India across both groups. While the video enhanced participants' knowledge about toxic chemicals and intentions to reduce exposure, they indicated that barriers hindered them from making behavioral changes.

Pregnancy, folic acid, and antiseizure medication

Abstract Background Although some antiseizure medications (ASMs) are teratogenic, most people with epilepsy need treatment in pregnancy. The risk of ASM fetotoxicity may be mitigated with folic acid. High-dose folic acid supplementation has traditionally been recommended before and during gestation despite little evidence of efficacy and safety for this patient group. Several studies have investigated the potential benefits and risks of folic acid supplements. Objective To provide an updated overview of the risks, benefits, and rationale for use of folic acid supplementation in relation to pregnant people of childbearing age using ASM. Materials and methods This is a narrative review based on an unstructured literature search of PubMed. We also scrutinized neurological and obstetrical guidelines. Results Antiseizure medication can decrease folate concentrations. In children exposed to ASM prenatally, those born to persons using folic acid supplements periconceptionally had lower risk of adverse neurodevelopment and preterm birth. It remains unclear whether the risk for congenital malformations can be equally alleviated. In studies of the general population, high plasma folate concentrations and/or high-dose folic acid supplements were associated with adverse neurodevelopmental outcomes. This has not been seen in children of mothers with epilepsy. However, an increased cancer risk has been found in children of mothers with epilepsy using high-dose folic acid supplements in pregnancy. Conclusion The optimal folic acid dose is not clear for persons of childbearing potential with epilepsy using ASM. Both low and excess folate status during pregnancy have been associated with adverse neurodevelopment. We propose an individual folic acid supplement dose that should be titrated based on maternal plasma folate concentrations during pregnancy.

Osteopathic Manipulative Treatment of Chronic Pelvic Pain due to High-Tone Pelvic Floor Dysfunction

Context: Chronic pelvic pain syndrome (CPPS) is a complex pain syndrome that affects 15%–30% of people of childbearing age (~10–20 million, US). Etiologies range from musculoskeletal conditions and visceral disease to neurological and psychological disorders. The interplay of many systems and disorders can manifest into a complex pathophysiology that is difficult to diagnose and treat. Dysfunction of the musculoskeletal system is often involved in patients with CPPS, either as the cause of pain or the result of underlying disease or dysfunction. Hypertonicity of pelvic floor muscles, myofascial trigger points, and dysfunctional shortening of the levator ani group of muscles contribute to the structural and functional abnormalities involved in CPPS. Osteopathic physicians are in a unique position to directly address this somatic dysfunction with a nonpharmacologic, nonsurgical approach: osteopathic manipulative treatment (OMT).Objectives: The purpose of this article is to review the literature on manual treatment efficacy for high-tone pelvic floor dysfunction (HTPFD) and the standardization of diagnosis to provide rational, medically based treatments. The second purpose is to elucidate the steps that the medical, and specifically the osteopathic profession can take to standardize pelvic floor evaluation, diagnosis, and treatment in the primary care setting.
 Methods: A search was conducted on the US National Library of Medicine’s PubMed database for studies involving manual therapy treatment for HTPFD. The authors excluded studies that described manual therapy interventions aimed at increasing pelvic floor muscle tone in patients with urinary incontinence and/or pelvic organ prolapse.Results: For perspective, the initial search using the keywords “chronic pelvic pain syndrome” led to 2,281 publications since 1974; the addition of “osteopathic” led to 10 results since 2009. The search for “high-tone pelvic floor dysfunction” led to 30 publications since 1992; the addition of “osteopathic” yielded no results. To evaluate the efficacy of manual therapy for HTPFD, the search was expanded to include any manual therapy protocols. While the consensus in the literature is that manual treatment for chronic pelvic pain (CPP) is efficacious, the finding is limited by the lack of a comprehensive protocol to appropriately diagnose and treat the patient. The authors propose a system to standardize the assessment of a patient with CPP in the primary care setting by an appropriately trained physician so that pelvic floor dysfunction is recognized, properly diagnosed and treated, or referred to specialized care.Conclusion: The literature supports that manual therapy is an effective treatment for CPP, and as primary care providers, osteopathic physicians are uniquely placed to recognize and treat patients with HTPFD, providing an empathetic, patient-centered approach. Standardization of the diagnosis and manual treatment of HTPFD is required to assess and monitor patients systematically. Development of an advanced training program for clinicians to learn diagnostic approaches and OMTfor the pelvic floor should be required since the techniques addressing the pelvic floor musculature are often not included in traditional training.

Up to Date in Pregnancy: Assessing Vaccination Status in Hepatitis C-Positive Pregnant Persons [ID: 1372896

INTRODUCTION: Hepatitis C virus (HCV) is the most commonly reported bloodborne infection in the United States. Over 65% of infections are among people of childbearing age leading to increased perinatal transmission. The American College of Obstetricians and Gynecologists recommends HCV screening for all pregnant persons. Prior to HCV treatment, the hepatitis B (HBV) vaccination series is recommended. Per recommendations from the Centers for Disease Control and Prevention, the HBV vaccination series should be given to unvaccinated pregnant persons. This study aims to assess the frequency of HCV-positive pregnant persons who are screened for HBV immunity. METHODS: A quality improvement project through retrospective chart review was performed at a single institution from October 2020 to October 2022. Patients identified as HCV positive in pregnancy were included. Data collected included patient demographics and infectious variables such as HCV viral load, HBV antigen/antibody testing, and whether patients underwent HCV treatment. RESULTS: From October 11, 2020, to October 11, 2022, 113 pregnant patients were noted to be HCV positive. Of this population, 95% were also screened with HBV antigen. Only 13 patients had a HBV surface antibody checked to assess vaccination or previous infection status, of whom 9 were previously immunized. In total, only 74% of patients had a HCV viral load checked, half of whom had a viral load present. Of the patients with a positive viral load, only 51% had planned or participated in HCV treatment. CONCLUSION: Pregnancy offers a unique opportunity to complete complex vaccination series for previously unimmunized individuals who are positive for HCV. This quality improvement project indicates a lack of screening and assessment for further HBV immunization in a vulnerable population.

The association between dietary inflammatory index with endometriosis: NHANES 2001-2006.

Endometriosis is a common chronic inflammatory and estrogen-dependent disease that mostly affects people of childbearing age. The dietary inflammatory index (DII) is a novel instrument for assessing the overall inflammatory potential of diet. However, no studies have shown the relationship between DII and endometriosis to date. This study aimed to elucidate the relationship between DII and endometriosis. Data were acquired from the National Health and Nutrition Examination Survey (NHANES) 2001-2006. DII was calculated using an inbuilt function in the R package. Relevant patient information was obtained through a questionnaire containing their gynecological history. Based on an endometriosis questionnaire survey, those participants who answered yes were considered cases (with endometriosis), and participants who answered no were considered as controls (without endometriosis) group. Multivariate weighted logistic regression was applied to examine the correlation between DII and endometriosis. Subgroup analysis and smoothing curve between DII and endometriosis were conducted in a further investigation. Compared to the control group, patients were prone to having a higher DII (P = 0.014). Adjusted multivariate regression models showed that DII was positively correlated with the incidence of endometriosis (P < 0.05). Analysis of subgroups revealed no significant heterogeneity. In middle-aged and older women (age ≥ 35 years), the smoothing curve fitting analysis results demonstrated a non-linear relationship between DII and the prevalence of endometriosis. Therefore, using DII as an indicator of dietary-related inflammation may help to provide new insight into the role of diet in the prevention and management of endometriosis.

Connecting clinical, environmental, and genetic factors point to an essential role for vitamin A signaling in the pathogenesis of congenital diaphragmatic hernia.

Congenital diaphragmatic hernia (CDH) is a developmental disorder that results in incomplete diaphragm formation, pulmonary hypoplasia, and pulmonary hypertension. Although a variety of genes have been linked to its etiology, CDH is not a monogenetic disease, and the cause of the condition is still unclear in the vast majority of clinical cases. By comparing human clinical data and experimental rodent data from the literature, we present clear support demonstrating the importance of vitamin A (vitA) during the early window of pregnancy when the diaphragm and lung are forming. Alteration of vitA signaling via dietary and genetic perturbations can create diaphragmatic defects. Unfortunately, vitA deficiency is chronic among people of child-bearing age, and this early window of diaphragm development occurs before many might be aware of pregnancy. Furthermore, there is an increased demand for vitA during this critical period, which exacerbates the likelihood of deficiency. It would be beneficial for the field to further investigate the connections between maternal vitA and CDH incidence, with the goal of determining vitA status as a CDH risk factor. Regular clinical monitoring of vitA levels in child-bearing years is a tractable method by which CDH outcomes could be prevented or improved.

Investigation of ABO and RhD blood groups in childbearing age people in rural areas of Yunnan Province

The participants in this study were 20-49 years old rural childbearing age people who received the National Free Preconception Health Examination Project (NFPHEP) in Yunnan Province during 2013 to 2019. The proportion of ABO and RhD blood groups among different ethnic groups and different areas were calculated. The proportion of 2 748 131 participants with blood group A phenotype was highest (32.60%), followed by O (30.60%), B (27.33%) and AB (9.47%). In the RhD blood system, the proportion of the RhD positivity (RhD+) and RhD negativity (RhD-) group were 99.29% and 0.71% respectively. The proportions blood groups were significantly different among ethnic groups and areas (all P<0.001). Among 18 ethnic groups with more than 3 000 participants, Yao (42.75%), Bouyei (40.58%) and Dai (40.37%) ethnic groups had higher proportion of blood group O phenotype than other ethnic groups. Wa ethnic groups had highest proportion of the A (40.15%) and AB phenotypes (11.23%). Miao ethnic group (34.70%) and Lahu ethnic group (34.42%) had higher proportion of blood group B phenotype than other ethnic groups. Wa ethnic group had the highest proportion of RhD-group (1.88%). In all 16 prefectures of Yunnan, the proportion of blood group O phenotype was highest in Xishuangbanna Dai Autonomous Prefecture (40.27%). Baoshan city (36.39%), Lincang city (36.22%) and Dali Bai autonomous prefecture (36.06%) had higher proportion of blood group A phenotype than other regions. Diqing Tibetan Autonomous Prefecture (30.83%) and Qujing city (30.48%) had higher proportion of blood group B phenotype than other areas, while Zhaotong city had a highest proportion of blood group AB phenotype (11.19%). The proportion of RhD-group was highest in Honghe hani and Yi nationality autonomous prefecture(1.37%). The A RhD+(39.36%), A RhD-(0.78%), AB RhD+(11.03%), AB RhD-(0.20%) and O RhD-(0.48%) blood groups were higher proportion in Wa ethnic group than in other ethnic groups (P<0.001).

Serum Vitamin E Reference Intervals in a Black Congolese Population of Kinshasa

Context: Vitamin E is a powerful antioxidant and plays an important role in human reproduction. However, micronutrient deficiency is a major public health problem, particularly in developing countries. This study aimed to establish reference intervals (RIs) for vitamin E in black Congolese people of childbearing age using an ELISA method to provide a reference for clinically assessing vitamin E status. Methods: A total of 127 healthy people between the ages of 20 and 42 who underwent check-ups were randomly selected for the study. ELISA method measured the level of vitamin E. The effect of gender on vitamin E level was assessed, and RI was established using a parametric approach. Results: Women showed significantly higher levels of vitamin E than men (p = 0.01). The RI of vitamin E in people of childbearing age was 3.71 to 13.72, 4.52 to 14.64, and 4.17 to 13.52 mg/L, respectively, for the whole population, women and men. Conclusion: Using an ELISA method, this study established RI for vitamin E in the black Congolese population of childbearing age. We also found that women had significantly higher vitamin E levels than men. The results could provide a scientific basis for interpreting vitamin status in people of childbearing age in our setting.

Peculiarities of the State of the Body's Immunoprotective Functions, Bacterioscopic and Cytological Studies in the Presence of a Chronic Inflammatory Process of the Reproductive System

At the current stage, the state of health of the Ukrainian nation of reproductive age is characterized by a low birth rate. Chronic inflammatory diseases of the reproductive system significantly affect the health of millions of people of childbearing age. Chronic inflammation is characterized by a protracted, often erased course, a tendency to relapse, the presence of complications and resistance to therapy. The development and formation of inflammatory diseases are based on interconnected processes that begin with acute inflammation and end with destructive changes, therefore the assessment of the body's adaptive capabilities is increasingly considered one of the most important health criteria. There is a whole series of integral hematological indicators that allow you to assess the state of various parts of the immune system without resorting to special research methods.
