Abstract
BACKGROUND Fine needle aspiration biopsy (FNAB), accompanied by classification systems for cytology, can offer a cheap and convenient option for the diagnosis of breast cancer in women with suspicious breast lumps. In this study, we aimed to assess the accuracy of the International Academy of Cytology (IAC) Yokohama system in a Vietnamese oncology centre. METHODS A retrospective cross-sectional study was conducted from November 2021 to April 2022 at Vietnam National Cancer Hospital. We included patients with full hospital records regarding breast lesions for which FNAB was indicated. A total of 803 patients' FNAB specimens were assessed according to the IAC Yokohama system. The basic characteristics were summarised using the appropriate summary measurements. The risk of malignancy (ROM) was calculated for each classification category. RESULTS The median age was 42.7 years (range: 14-85). The mean size of the lesions was 17.9 mm (range: 4-123 mm). We had 215 histopathological reports. The most common benign and malignant diagnoses were fibroadenoma and invasive carcinoma, respectively. The ROM for categories II, III, IV, and V was calculated as 3.4%, 37.5%, 95%, and 99.2% respectively. The sensitivity, specificity, positive predictive value, and negative predictive value were 96.4%, 97.2%, 98.5%, and 93.2%, respectively. CONCLUSION The IAC Yokohama system offers a good option with which to predict underlying breast pathology using a simple and cheap procedure. However, pathologists require continuous training to ensure accurate interpretation of the slides.

Abstract
Background Vietnam was one of the countries pursuing the goal of "Zero-COVID" and had effectively achieved it in the first three waves of the pandemic. However, the spread of the Delta variant was outbreak first in Vietnam in late April 2021, in which Ho Chi Minh City was the worst affected. This study surveyed the public's knowledge, attitude, perception, and practice (KAPP) toward COVID-19 during the rapid rise course of the outbreak in Ho Chi Minh City. Methods This cross-sectional survey was conducted from 30th September to 16th November 2021, involving 963 residents across the city. We asked residents a series of 21 questions. The response rate was 76.6%. We set a priori level of significance at α = 0.05 for all statistical tests. Results The residents' KAPP scores were 68.67% ± 17.16, 77.33% ± 18.71, 74.7% ± 26.25, and 72.31% ± 31, respectively. KAPP scores of the medical staff were higher than the non-medical group. Our study showed positive, medium-strong Pearson correlations between knowledge and practice (r = 0.337), attitude and practice (r = 0.405), and perception and practice (r = 0.671; p < 0.05). We found 16 rules to estimate the conditional probabilities among KAPP scores via the association rule mining method. Mainly, 94% confident probability of participants had {Knowledge=Good, Attitude=Good, Perception=Good}, as well as {Practice=Good} (in rule 9 with support of 17.6%). In opposition to around 86% to 90% of the times, participants had levels of {Perception=Fair, Practice=Poor} given with either {Attitude=Fair} or {Knowledge=Fair} (according to rules 1, 2, and rules 15, 16 with a support of 7-8%). Conclusion In addition to the government's directives and policies, citizens' knowledge, attitude, perception, and practice are considered one of the critical preventive measures during the COVID-19 pandemic. The results affirmed the good internal relationship among K, A, P, and P scores creating a hierarchy of healthcare educational goals and health behavior among residents.

Abstract
BACKGROUND Meta-analyses are on top of the evidence-based medicine pyramid, yet many of them are not completed after they are begun. Many factors impacting the publication of meta-analysis works have been discussed, and their association with publication likelihood has been investigated. These factors include the type of systematic review, journal metrics, h-index of the corresponding author, country of the corresponding author, funding sources, and duration of publication. In our current review, we aim to investigate these various factors and their impact on the likelihood of publication. A comprehensive review of 397 registered protocols retrieved from five databases was performed to investigate the different factors that might affect the likelihood of publication. These factors include the type of systematic review, journal metrics, h-index of the corresponding author, country of the corresponding author, funding sources, and duration of publication. RESULTS We found that corresponding authors in developed countries and English-speaking countries had higher likelihoods of publication: 206/320 (p = 0.018) and 158/236 (p = 0.006), respectively. Factors affecting publications are the countries of corresponding author (p = 0.033), whether they are from developed countries (OR: 1.9, 95% CI: 1.2-3.1, p = 0.016), from English-speaking countries (OR: 1.8, 95% CI: 1.2-2.7, p = 0.005), update status of the protocol (OR: 1.6, 95% CI: 1.0-2.6, p = 0.033), and external funding (OR: 1.7, 95% CI: 1.1-2.7, p = 0.025). Multivariable regression retains three variables as significant predictors for the publication of a systematic review: whether it is the corresponding author from developed countries (p = 0.013), update status of the protocol (p = 0.014), and external funding (p = 0.047). CONCLUSION Being on top of the evidence hierarchy, systematic review and meta-analysis are the keys to informed clinical decision-making. Updating protocol status and external funding are significant influences on their publications. More attentions should be paid to the methodological quality of this type of publication.

Abstract
OBJECTIVES Vietnam is one of the countries in highly endemic areas of hepatitis B virus (HBV) infection in the world. Our study aims to determine the prevalence of HBV infection among different age groups of workers who had been included for annual general health checkups. METHODS This cross-sectional study was conducted at the Health Screening Department, University Medical Center at Ho Chi Minh City, Vietnam, using anonymous data from employees who had health checkups from June 2017 to June 2018. RESULTS A total of 5727 subjects were included, with an overall HBV prevalence of 9.0%. The prevalence of HBV infection was significantly higher in men and lowest in the age groups of 18-30. In multivariable analysis, the variables that were independently associated with HBV infection were male gender (Odd ratio (OR), 2.03; 95% confidence interval (CI), 1.58-2.60; p < 0.001), older than 30 years old (age group of 31-40: OR 1.7; 95% CI, 1.33-2.18; p < 0.001; of 41-50, OR 1.82; 95% CI, 1.37-2.43; p < 0.001); high total cholesterol (OR, 0.77; 95% CI, 0.64-0.94; p = 0.011), high triglyceride (OR, 0.53; 95% CI, 0.42-0.65; p < 0.001), and having significant fibrosis (OR, 2.7; 95% CI 1.85-3,95; p < 0.001). CONCLUSIONS The prevalence of HBV infection among employees on health assessments is still high (9%), even in the age group under 30 (7%). Male, age group older than 30, and significant liver fibrosis were the factors related to HBV infection. High cholesterol and level triglyceride were protective factors against HBV infection.

Abstract
BACKGROUND Chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature syndrome is a rare, hereditary, autoinflammatory disease. However, there are few cases reported in the literature. Therefore, we conduct this systematic review to summarize current evidence. METHODS We conducted a systematic search in July 2021 using 11 different electronic databases. The included articles were screened according to our inclusion and exclusion criteria and assessed using an appropriate quality assessment tool. Then, the relevant data were extracted and summarized in tables accordingly. Each step of the previous one was done by 3 independent reviewers, and the conflicts were resolved by discussion and sometimes by counseling a senior member. RESULTS The final included studies were 18 articles with 34 cases (mean age = 8 years, male/female = 19/15). The most reported symptoms and signs were fever 97.1%, erythematous plaques 76.5%, arthralgia 67.6%, hepatomegaly 61.8%, violaceous hue 61.8%, lipodystrophy in extremities 53.1% in addition to low weight and height. Rare features were reported too. The laboratories were not specific, which may be explained by a systemic inflammatory response. Vasculitis was the dominant feature in the skin biopsy, whereas the calcification in the basal ganglia was a prominent sign in many cases. CONCLUSIONS Fever, skin lesions, and systemic inflammatory response were the prominent features of chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature syndrome. The clinical picture is the main guide in addition to the pathological findings. Mutation detection is the confirmatory test. Prednisolone is the most effective reported treatment for acute presentations in the literature.

Abstract
In May 2022, the world witnessed the re-emergence of the zoonotic disease monkeypox. While this was not the first epidemic of this disease, what differentiated the outbreak was the rapid global spread and increase of cases, which led the WHO to declare monkeypox a global health emergency. Although the disease spreads mainly through inadequately cooked meat of various rodent species, this virus also shows droplet, respiratory, sexual, and even vertical transmission. Monkeypox further multiplies in lymphoproliferative organs and presents with a classical smallpox-like rash, fever, headache, and muscle aches. Diagnosis is confirmed with a polymerase-chain-reaction test and is managed largely supportively with possible usage of some antivirals and immunoglobulins. Moreover, some pre-exposure and postexposure prophylactic vaccines have been developed. This paper aims to conduct an in-depth review of the historical epidemics, transmission, pathophysiology, clinical presentation, and management of the monkeypox disease.

Abstract
OBJECTIVE Major depressive disorder (MDD) is the second-most prevalent mental health condition in Vietnam. This study aims to validate the Vietnamese versions of the self-reported and clinician-rated Quick Inventory of Depressive Symptomatology (QIDS-SR and QIDS-C, respectively) and the Patient Health Questionnaire (PHQ-9), and to assess the correlations between the QIDS-SR, QIDS-C, and PHQ-9. METHODS 506 participants with MDD (mean age, 46.3 years; 55.5% women) were assessed using the Structured Clinical Interview for DSM-5. The internal consistency, diagnostic efficiency, and concurrent validity of the Vietnamese versions of QIDS-SR, QIDS-C, and PHQ-9 were determined using the Cronbach's alpha, receiver operating characteristic curve, and Pearson correlation coefficient, respectively. RESULTS The Vietnamese versions of QIDS-SR, QIDS-C, and PHQ-9 demonstrated acceptable validity, with an area under the receiver operating characteristic curve of 0.901, 0.967, and 0.864, respectively. Sensitivity and specificity, respectively, were 87.8% and 77.8% for QIDS-SR and 97.6% and 86.2% for QIDS-C at the cut-off score of 6, and were 82.9% and 70.1% for PHQ-9 at the cut-off score of 4. Cronbach's alphas for QIDS-SR, QIDS-C, and PHQ-9 were 0.709, 0.813, and 0.745, respectively. The PHQ-9 highly correlated with the QIDS-SR (r = 0.77, p < 0.001) and the QIDS-C (r = 0.75, p < 0.001). CONCLUSION The Vietnamese versions of the QIDS-SR, QIDS-C, and PHQ-9 are valid and reliable tools for screening of MDD in primary healthcare settings.

Abstract
BACKGROUND This study was designed to assess the impact of postoperative atrial fibrillation (POAF) on short- and long-term outcomes after cardiac surgery. METHODS We prospectively assessed POAF concerning outcomes in 379 adult patients who had undergone cardiac surgery in two heart surgery centers with a follow-up period of one year for every patient. The effects of POAF on postoperative events were evaluated using Logistic regression, Cox regression (adjusted for propensity score), and Kaplan-Meier analysis. RESULTS The incidence of POAF was 27.2%. Multivariable logistic regression analysis revealed POAF was associated with an increased risk of 6-month (OR = 5.36; CI: 1.51-18.94; p = 0.009), and 1-year mortality (OR = 4.56; CI: 1.29-16.04; p = 0.018) as well as Major Adverse Cardiocerebral Events (MACEs; acute MI, cardiac arrest, low cardiac output after surgery, third-degree atrioventricular block or stroke; OR = 3.02; CI: 1.29-7.05; p = 0.011), Intensive Care Unit (ICU) stay > 3 days (OR = 2.39; CI: 1.14-5.00; p = 0.021), and postoperative stay > 14 days (OR = 3.12; CI: 1.65-5.90; p < 0.001). Multivariable Cox regression analysis showed POAF as an independent predictor of mortality at one year (HR = 2.86; CI: 1.05-7.75; p = 0.038). Discharge plans including statin and beta-blocker had an independent association with a reduced mortality at one year (HR = 0.22; CI: 0.05-0.96; p = 0.045; HR = 0.16; CI: 0.03-0.87; p = 0.034, respectively). CONCLUSIONS POAF is associated with an increased risk of morbidity, all-cause mortality, and hospital duration. Statins and beta-blockers that were included in discharge plans had an independent association with reduction in 1-year all-cause mortality.

Abstract
OBJECTIVE This research was conducted to identify the prevalence and associated factors of depressive disorders, as well as evaluate the recognition rate of general practitioners in detecting these mental health issues in primary care. METHOD Five hundred and twelve participants (55.3% female, mean age = 46.35 years) were assessed by psychiatrists based on the DSM-5 clinical procedures over a two-month survey in a primary care facility in Ho Chi Minh City, Vietnam. RESULTS There were 15.8% (95% confidence interval [CI] 12.9-19.2) of the population having depressive disorders, with major depressive disorder being the most prevalent subtype at 8% (95% CI 5.9-10.6). General practitioners could detect depressive disorders in 2.5% of all cases (95% CI .5-7.7). Significantly linked with depressive disorders in multivariable analysis were Chinese ethnic or other minority races (adjusted odds ratios [aOR] = 4.10, 95% CI 1.04-16.12), and low economic status (aOR = 5.41, 95% CI 1.29-22.59). CONCLUSIONS The high prevalence of depressive disorders in outpatients of primary care clinics may raise the awareness of the practitioners about screening and other appropriate actions to tackle the issue.

Abstract
The regulatory T (Treg) and T helper 17 (Th17) cells modulate the immune response in chronic hepatitis B virus (HBV) infection by promoting immune tolerance and restricting liver damage or stimulating inflammatory response and rendering hepatocyte injury. These cells act through signaling transcription factors and secreting cytokines. We aimed to observe the percentages of Treg, Th17 cells, and their messenger RNA (mRNA) level of forkhead box protein 3 (Foxp3) and retinoid orphan receptor γt (RORγt) in the chronic hepatitis B (CHB)-infected group and CHB patients with hepatitis flare (HF). We recruited 103 participants, including 88 CHB-infected cases and 15 healthy controls (HCs) in Ho Chi Minh City. CHB cases were enrolled into two groups: HBeAg+ CHB infection (e+CHBI; n = 42) and HF (including 20 mild HF and 26 severe HF [sHF]). The Foxp3(+)Treg and Th17 cells were measured by flow cytometry. The mRNA levels of Foxp3 and RORγt were analyzed by real-time polymerase chain reaction. The percentages of Foxp3(+)Treg, of Th17, and the Foxp3(+)Treg/Th17 ratio were significantly higher in the sHF compared to the e+CHBI group. The sHF and e+CHBI groups had significantly higher mRNA levels of Foxp3 and RORγt compared to the HC group. Furthermore, a special subset, interleukin 17A(+)Foxp3(+)Treg cells, were observed with a significantly higher percentage in the sHF compared to the e+CHBI group. This finding revealed the contributions of this new subset on the severe flare cases. Our results explained the diversity of T cells and their subsets in the immune response in CHB. This subset should be further investigated as a specific tool in HBV immune response.

Abstract
BACKGROUND Current therapeutic agents, including nifurtimox and benznidazole, are not sufficiently effective in the chronic phase of Trypanosoma cruzi infection and are accompanied by various side effects. In this study, 120 kinds of extracts from medicinal herbs used for Kampo formulations and 94 kinds of compounds isolated from medicinal herbs for Kampo formulations were screened for anti-T. cruzi activity in vitro and in vivo. METHODS As an experimental method, a recombinant protozoan cloned strain expressing luciferase, namely Luc2-Tulahuen, was used in the experiments. The in vitro anti-T. cruzi activity on epimastigote, trypomastigote, and amastigote forms was assessed by measuring luminescence intensity after treatment with the Kampo extracts or compounds. In addition, the cytotoxicity of compounds was tested using mouse and human feeder cell lines. The in vivo anti-T. cruzi activity was measured by a murine acute infection model using intraperitoneal injection of trypomastigotes followed by live bioluminescence imaging. RESULTS As a result, three protoberberine-type alkaloids, namely coptisine chloride, dehydrocorydaline nitrate, and palmatine chloride, showed strong anti-T. cruzi activities with low cytotoxicity. The IC50 values of these compounds differed depending on the side chain, and the most effective compound, coptisine chloride, showed a significant effect in the acute infection model. CONCLUSIONS For these reasons, coptisine chloride is a hit compound that can be a potential candidate for anti-Chagas disease drugs. In addition, it was expected that there would be room for further improvement by modifying the side chains of the basic skeleton.

Abstract
We report the structural functionalization of the terminal amino group of N1 -(7-chloroquinolin-4-yl) butane-1,4-diamine, leading to a series of 7-chloro-4-aminoquinoline derivatives, and their evaluation as potent anti-malarial and anti-viral agents. Some compounds exhibited promising anti-malarial effects against the Plasmodium falciparum 3D7 (chloroquine-sensitive) and Dd2 (chloroquine-resistant) strains. In addition, these compounds were assayed in vitro against influenza A virus (IAV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Compound 5 h, bearing an N-mesityl thiourea group, displayed pronounced anti-infectious effects against malaria, IAV, and SARS-CoV-2. These results provide new insights into drug discovery for the prevention or treatment of malaria and virus co-infection.

Abstract
Introduction: Telepharmacy is widely known as the delivery of pharmacy care offered by registered pharmacists and pharmacies using telecommunication technologies to patients at a distance. We conducted a systematic review of the reported usages, benefits, and limitations of telepharmacy models worldwide to further clarify the pros and cons of a telepharmacy model. Methods: A total of 39 relevant articles was included after searching for articles with a fixed term on four databases, including PubMed, Virtual Health Library (VHL), Global Health Library (GHL), and Google Scholar, as of April 2021. Results: Our review suggested that telepharmacy has played an essential role in addressing pharmacist shortages and helping patients both safely and effectively administer medications in underserved areas. During the COVID-19 pandemic, remote dispensing and counseling are effective measures to avoid infection. Conclusion: Telepharmacy could potentially replace or complement pharmaceutical-related activities, facilitating future innovation in the health care industry.

Evaluation of the Effectiveness of the Policy of Holding the Second Dose of Vaccination: Lessons from the Outbreak in Ho Chi Minh City. Vaccines (Basel) 2023; 11:vaccines11020293. [PMID: 36851172 PMCID: PMC9967005 DOI: 10.3390/vaccines11020293] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 01/11/2023] [Accepted: 01/21/2023] [Indexed: 01/31/2023] Open
Abstract
The coronavirus disease 2019 (COVID-19) pandemic has caused a lot of ethical controversy in the equal provision of healthcare, including vaccination. Therefore, our study was designed to assess the impact of Ho Chi Minh City's policy to hold the second dose of the COVID-19 vaccine. Using a cross-sectional study design to assess low saturation of peripheral oxygen (SPO2) risk based on vaccination status, we included patients who were confirmed to have SARS-CoV-2 and were treated at home. The stepwise method was used to determine participants' low SPO2 risk-related factors. The average age of the 2836 respondents was 46.43 ± 17.33 (years). Research results have shown that seven factors are related to the low SPO2 status of participants, including age, sneezing, shortness of breath, coughing, and fainting as COVID-19 symptoms, the number of people living with COVID-19, and a history of lung disease. A statistically significant (p = 0.032) finding in this study was that fully vaccinated patients had a 6% lower risk of low SPO2 compared to the first dose less than 21 days group. This result was similar in the vaccine holder group (p < 0.001). Holding the second dose of the COVID-19 vaccine is associated with a lower SPO2 risk than that of fully vaccinated patients. Therefore, this approach should be considered by governments as it could bring a greater benefit to the community.

Abstract
Panax ginseng is a common natural product, which is well-known to have a wide range of pharmacological activities in cancer. Its metabolite, compound K (CK), has been reported to have anticancer activity. We aimed to systematically review the literature for evidence of anticancer effects of CK. We conducted a systematic search in eight databases. We included all in vitro and in vivo studies investigating the anticancer effects of CK with no restrictions. Quality assessment was applied by ToxRTool. Fifty-four articles were included in our study. The purity of CK in our included studies was at least 95%. The in vitro studies reported that CK had a potential anticancer activity on several cell lines including human lung cancer cell lines (A549, PC-9), nasopharyngeal carcinoma cell line (Hk-1), liver cancer cell line (BEL 7402), and pediatric acute myeloid leukemia cell lines (Kasumi-1, MV4-11). The in vivo studies reported a significant decrease in tumor volume in mice treated with CK. CK is a potential supplementary treatment in cancer chemotherapies. The safety and further clinical trials of CK should be explored for future drug development.

Abstract
Background Outbreak of SARS-CoV-2 pandemic has caused millions of deaths and lifelong consequences since December 2019. We attempted to evaluate the incidence, distribution, and risk factors associated with death after applying the social distance strategy to the second wave of SARS-CoV-2 in the Danang outbreak in Vietnam. Methods We retrospectively reviewed the online the Danang Hospital reports, gathering the epidemiological history of confirmed SARS-CoV-2 patients. We then conducted a descriptive analysis of Fisher's Phi Coefficient and Cramer's, along with multiple logistic regression models to test the effects of symptomatology and control measures performed by Vietnamese government. The last report we examined on August 29, 2020. Results A total of 389 SARS-CoV-2 confirmed cases were related to the Danang outbreak are included in our analysis with a mean age of 47.1 (SD = 18.4), involving 154 men and 235 women, with 34 cases of death and 355 were alive. The study showed significant results related to age, quarantine measures, previous negative SARS-CoV-2 test, and a range of symptoms, including shortness of breath and myalgia (p-value <0.05). Our multiple-variable analysis suggested the significant risk of death was related to age, severe symptomology, undetected SARS-CoV-2 test results, and prior quarantined SARS-CoV-2 history. Conclusions Vietnamese authorities had implemented successful quarantine practices to control the SARS-CoV-2 outbreaks. However, this virus has shown dynamic spread beyond the ability of the country to control its transmission. Adequate screening, social distancing, and adequate care of elderly and healthcare workers can lower the risk of future outbreaks.

Abstract
Phototherapy is the main treatment of neonatal hyperbilirubinemia to prevent encephalopathy. It is generally believed to be safe; however, some studies have shown it might be associated with cancer development. In this systematic review and meta-analysis, we aimed to assess the effect of neonatal phototherapy on future cancer risk. A systematic search in 13 databases was conducted in December 2018 and updated in August 2022 to identify studies that report cancer development after exposure to phototherapy. Throughout the study period, regular manual searches were also conducted to include new studies. A meta-analysis using R programming language was done in which the odds ratios (ORs) with 95% confidence intervals (CIs) were estimated and pooled using the reported adjusted and unadjusted data. Fifteen studies were included. A statistically significant association was detected between neonatal phototherapy and any type of cancer (OR 1.24; 95% CI 1.1, 1.4), any hematopoietic cancer (OR 1.49; 95% CI 1.17, 1.91), any leukemia (OR 1.35; 95% CI 1.08, 1.67), and myeloid leukemia (OR 2.86; 95% CI 1.4, 5.84). The other investigated cancers (lymphoid leukemia, Hodgkin's lymphoma, kidney cancer, nervous system cancer, and skin cancer) were not associated with phototherapy. Conclusions: Phototherapy may carry a possible risk of future cancers. Future research is needed to quantify the magnitude of the cancer risk. These future studies should consider predictors of preterm birth or exclude premature babies from their analysis. What is Known • There were various reports about the possible association between phototherapy in neonates and the increased risk of cancer in the future. What is New • A statistically significant association between phototherapy and various hematopoietic cancers (especially myeloid leukemia) was recorded. • The effect of the duration of phototherapy on the increased risk of hematopoietic cancers is yet unclear.

Non-Invasive Prenatal Testing (NIPT) Implementation in Japan: A Comparison with the United Kingdom, Germany, Italy, Sweden, and Taiwan. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:16404. [PMID: 36554285 PMCID: PMC9778094 DOI: 10.3390/ijerph192416404] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 11/10/2022] [Accepted: 11/22/2022] [Indexed: 06/17/2023]
Abstract
INTRODUCTION The Non-Invasive Prenatal Testing (NIPT) guideline was issued and applied in 2013 by the Japanese Medical Association. Since being issued, the NIPT practice in Japan still has some problems related to indication, access, cost coverage and uniformity. Therefore, our study aimed to identify the Japanese challenges of adopting NIPT into prenatal diagnosis by comparing the system and process with other countries. METHOD The United Kingdom, Germany, Italy, Sweden, and Taiwan were purposefully selected for comparison. All the countries, including Japan, introduced NIPT. The literature and information searches were conducted using PubMed, SCOPUS, Google Scholar, CiNii and Google searching engine. RESULTS The process of NIPT in Japan was very different from the other countries. Japan is the only country that indicated NIPT for only pregnant women over 35 years old in certificated facilities and did not have a policy regarding providing information on prenatal screening and NIPT to all women. Japan also did not have a policy regarding abortion due to fetal abnormalities. The practice of NIPT guidelines is different between non-certified and certified facilities. NIPT fee was the highest in Japan and was not covered by insurance. CONCLUSION Pregnant women in Japan suffered from disparities in information access, economic burden, geographic location, and practice of NIPT guidelines between the certified and the non-certified facilities. Pregnant women-centered prenatal diagnosis policy, including NIPT, should be established in Japan by learning cases from other countries.
