CK2α-mediated phosphorylation of GRP94 facilitates the metastatic cascade in triple-negative breast cancer.

Distant metastasis is a significant hallmark affecting to the high death rate of patients with triple-negative breast cancer (TNBC). Thus, it is crucial to identify and develop new therapeutic strategies to hinder cancer metastasis. While emerging studies have hinted a pivotal role of glucose-regulated protein 94 (GRP94) in tumorigenesis, the exact biological functions and molecular mechanisms of GRP94 in modulating cancer metastasis remain to be elucidated. Our study demonstrated an increased expression of GRP94 in TNBC correlated with metastatic progression and unfavorable prognosis in patients. Functionally, we identified that GRP94 depletion significantly diminished TNBC tumorigenesis and subsequent lung metastasis. In contrast, GRP94 overexpression exacerbated the invasiveness, migration, and lung metastasis of non-TNBC cells. Mechanistically, we found that casein kinase 2 alpha (CK2α) active in advanced breast cancer phosphorylated GRP94 at a conserved serine 306 (S306) residue. This phosphorylation increased the stability of GRP94 and enhanced its interaction with LRP6, leading to activation of canonical Wnt signaling. From a therapeutic standpoint, we found that benzamidine, a novel CK2α inhibitor, effectively suppressed GRP94 phosphorylation, LRP6 stabilization, and metastasis of TNBC. Our results point to the critical role of CK2α-mediated GRP94 phosphorylation in TNBC metastasis through activation of Wnt signaling, highlighting GRP94 as a therapeutic target to impede TNBC metastasis.

Dihydrostilbenes and flavonoids from whole plants of Jacobaea vulgaris.

The isolation of previously undescribed 12 compounds from the MeOH extract of Jacobaea vulgaris whole plants is disclosed, comprising 11 dihydrostilbenes (1-11) and one flavanone (12), and eight known compounds (six flavonoids, one dihydrostilbene, and one caffeoylquinic acid). Structural elucidation employed spectroscopic methods, including 1D and 2D NMR spectroscopy, HRESIMS, and ECD calculations. Evaluation of the compounds' effects on PCSK9 and LDLR mRNA expression revealed that compounds 1 and 3 downregulated PCSK9 mRNA while increasing LDLR mRNA expression, suggesting potential cholesterol-lowering properties.

Clinical feature, GALC variant spectrum, and genotype-phenotype correlation in Korean Krabbe disease patients: Multicenter experience over 13 years.

Krabbe disease (KD) is an autosomal recessive neurodegenerative disorder caused by deficiency of the galactocerebrosidase (GALC) due to variants in the GALC gene. Here, we provide the first and the largest comprehensive analysis of clinical and genetic characteristics, and genotype-phenotype correlations of KD in Korean in comparison with other ethnic groups. From June 2010 to June 2023, 10 patients were diagnosed with KD through sequencing of GALC. Clinical features, and results of GALC sequencing, biochemical test, neuroimaging, and neurophysiologic test were obtained from medical records. An additional nine previously reported Korean KD patients were included for review. In Korean KD patients, the median age of onset was 2 years (3 months-34 years) and the most common phenotype was adult-onset (33%, 6/18) KD, followed by infantile KD (28%, 5/18). The most frequent variants were c.683_694delinsCTC (23%) and c.1901T>C (23%), while the 30-kb deletion was absent. Having two heterozygous pathogenic missense variants was associated with later-onset phenotype. Clinical features were similar to those of other ethnic groups. In Korean KD patients, the most common phenotype was the adult-onset type and the GALC variant spectrum was different from that of the Caucasian population. This study would further our understanding of KD.

IL-27-induced PD-L1highSca-1+ innate lymphoid cells suppress contact hypersensitivity in an IL-10-dependent manner.

Innate lymphoid cells (ILCs) play an important role in maintaining tissue homeostasis and various inflammatory responses. ILCs are typically classified into three subsets, as is the case for T-cells. Recent studies have reported that IL-10-producing type 2 ILCs (ILC210s) have an immunoregulatory function dependent on IL-10. However, the surface markers of ILC210s and the role of ILC210s in contact hypersensitivity (CHS) are largely unknown. Our study revealed that splenic ILC210s are extensively included in PD-L1highSca-1+ ILCs and that IL-27 amplifies the development of PD-L1highSca-1+ ILCs and ILC210s. Adoptive transfer of PD-L1highSca-1+ ILCs suppressed oxazolone-induced CHS in an IL-10-dependent manner Taken together, our results demonstrate that ILC210s are critical for the control of CHS and suggest that ILC210s can be used as target cells for the treatment of CHS.

Clinical use of whole exome sequencing in children with developmental delay/intellectual disability.

BACKGROUND: Identifying the underlying etiology of developmental delay/intellectual disability (DD/ID) is challenging but important. The genetic diagnosis of unexplained DD/ID helps in the treatment and prognosis of the disability in patients. In this study, we reported our experience of using whole exome sequencing (WES) of children with unexplained DD/ID. METHODS: We conducted a retrospective analysis of WES results of children under 19 years of age with unexplained DD/ID between January 2020 and December 2021. The demographic data of all patients and variants identified through WES were evaluated. Furthermore, we evaluated the clinical characteristics that influenced the identification of genetic causes. RESULTS: Forty-one patients with DD/ID were included, of whom 21 (51.2 %) were male. The average age at symptom onset was 1.6 ± 1.3 years, and the duration from symptom onset to diagnosis was 3.1 ± 3.7 years. Hypotonia was the most common symptom (17 patients, 41.5 %), and epilepsy was confirmed in 10 patients (24.4 %). Twenty-two pathogenic/likely pathogenic variants were identified in 20 patients, and three variants of uncertain significance were identified in three patients. Family-based trio Sanger sequencing for candidate variants of 12 families was conducted; 10 variants were de novo, one variant paternally inherited, and two variants compound heterozygous. The diagnostic yield of WES for DD/ID was 48.8 % and was significantly high in patients with an early onset of DD/ID and facial dysmorphism. In contrast, patients with autism spectrum disorder (ASD) were more likely to have negative WES results compared with others without ASD. CONCLUSION: The diagnostic yield of WES was 48.8 %. We conclude that patients' characteristics, such as dysmorphic features and the age of symptom onset, can predict the likelihood that WES will identify a causal variant of a phenotype.

Women's experience of childbirth care in health facilities: a qualitative assessment of respectful maternity care in Afghanistan.

BACKGROUND: Respectful maternity care (RMC) remains a key challenge in Afghanistan, despite progress on improving maternal and newborn health during 2001-2021. A qualitative study was conducted in 2018 to provide evidence on the situation of RMC in health facilities in Afghanistan. The results are useful to inform strategies to provide RMC in Afghanistan in spite of the humanitarian crisis due to Taliban's takeover in 2021. METHODS: Focus group discussions were conducted with women (4 groups, 43 women) who had used health facilities for giving birth and with providers (4 groups, 21 providers) who worked in these health facilities. Twenty key informant interviews were conducted with health managers and health policy makers. Motivators for, deterrents from using, awareness about and experiences of maternity care in health facilities were explored. RESULTS: Women gave birth in facilities for availability of maternity care and skilled providers, while various verbal and physical forms of mistreatment were identified as deterrents from facility use by women, providers and key informants. Low awareness, lack of resources and excessive workload were identified among the reasons for violation of RMC. CONCLUSION: Violation of RMC is unacceptable. Awareness of women and providers about the rights of women to respectful maternity care, training of providers on the subject, monitoring of care to prevent mistreatment, and conditioning any future technical and financial assistance to commitments to RMC is recommended.

Approaches to improve and adapt maternal mortality estimations in low- and middle-income countries: A scoping review.

BACKGROUND: In the absence of robust vital registration systems, many low- and middle-income countries (LMICs) rely on national surveys or routine surveillance systems to estimate the maternal mortality ratio (MMR). Although the importance of MMR estimates in ending preventable maternal deaths is acknowledged, there is limited research on how different approaches are used and adapted, and how these adaptations function. OBJECTIVES: To assess methods for estimating maternal mortality in LMICs and the rationale for these modifications. SEARCH STRATEGY: A literature search with the terms "maternal death", "surveys" and "low- and middle-income countries" was performed in Medline, Embase, Web of Science, Scopus, CINAHL, APA PsycINFO, ERIC, and IBSS from January 2013 to March 17, 2023. SELECTION CRITERIA: Studies were eligible if their main focus was to compare, adapt, or assess methods to estimate maternal mortality in LMICs. DATA COLLECTION AND ANALYSIS: Titles and abstracts were screened using Rayyan. Relevant articles were independently reviewed by two reviewers against inclusion criteria. Data were extracted on mortality measurement methods, their context, and results. MAIN RESULTS: Nineteen studies were included, focusing on data completeness, subnational estimates, and community involvement. Routinely generated MMR estimates are more complete when multiple data sources are triangulated, including data from public and private health facilities, the community, and local authorities (e.g. vital registration, police reports). For subnational estimates, existing (e.g. the sisterhood method and reproductive-age mortality surveys [RAMOS]) and adapted methods (e.g. RAMOS 4 + 2 and Pictorial Sisterhood Method) provided reliable confidence intervals. Community engagement in data collection increased community awareness of maternal deaths, provided local ownership, and was expected to reduce implementation costs. However, most studies did not include a cost-effectiveness analysis. CONCLUSION: Household surveys with community involvement and RAMOS can be used to increase data validity, improve local awareness of maternal mortality estimates, and reduce costs in LMICs.

Dendropanoxide Attenuates High Glucose-induced Oxidative Damage in NRK-52E Cells via AKT/mTOR Signaling Pathway.

Hyperglycemia is a potent risk factor for the development and progression of diabetes-induced nephropathy. Dendropanoxide (DPx) is a natural compound isolated from Dendropanax morbifera (Araliaceae) that exerts various biological effects. However, the role of DPx in hyperglycemia-induced renal tubular cell injury remains unclear. The present study explored the protective mechanism of DPx on high glucose (HG)-induced cytotoxicity in kidney tubular epithelial NRK-52E cells. The cells were cultured with normal glucose (5.6 mM), HG (30 mM), HG + metformin (10 µM), or HG + DPx (10 µM) for 48 h, and cell cycle and apoptosis were analyzed. Malondialdehyde (MDA), advanced glycation end products (AGEs), and reactive oxygen species (ROS) were measured. Protein-based nephrotoxicity biomarkers were measured in both the culture media and cell lysates. MDA and AGEs were significantly increased in NRK-52E cells cultured with HG, and these levels were markedly reduced by pretreatment with DPx or metformin. DPx significantly reduced the levels of kidney injury molecule-1 (KIM-1), pyruvate kinase M2 (PKM2), selenium-binding protein 1 (SBP1), or neutrophil gelatinase-associated lipocalin (NGAL) in NRK-52E cells cultured under HG conditions. Furthermore, treatment with DPx significantly increased antioxidant enzyme activity. DPx protects against HG-induced renal tubular cell damage, which may be mediated by its ability to inhibit oxidative stress through the protein kinase B/mammalian target of the rapamycin (AKT/mTOR) signaling pathway. These findings suggest that DPx can be used as a new drug for the treatment of high glucose-induced diabetic nephropathy.

Chlorophyll a and novel synthetic derivatives alleviate atopic dermatitis by suppressing Th2 cell differentiation via IL-4 receptor modulation.

Atopic dermatitis (AD) treatment has largely relied on non-specific broad immunosuppressants despite their long-term toxicities until the approval of dupilumab, which blocks IL-4 signaling to target Th2 cell responses. Here, we report the discovery of compound 4aa, a novel compound derived from the structure of chlorophyll a, and the efficacy of chlorophyll a to alleviate AD symptoms by oral administration in human AD patients. 4aa downregulated GATA3 and IL-4 in differentiating Th2 cells by potently blocking IL-4 receptor dimerization. In the murine model, oral administration of 4aa reduced the clinical severity of symptoms and scratching behavior by 76% and 72%, respectively. Notably, the elevated serum levels of Th2 cytokines reduced to levels similar to those in the normal group after oral administration of 4aa. Additionally, the toxicological studies showed favorable safety profiles and good tolerance. In conclusion, 4aa may be applied for novel therapeutic developments for patients with AD.

Preventive Effect of Ecklonia cava Extract on DSS-Induced Colitis by Elevating Intestinal Barrier Function and Improving Pathogenic Inflammation.

Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease, is a complex gastrointestinal disorder with a multifactorial etiology, including environmental triggers, autoimmune mechanisms, and genetic predisposition. Despite advancements in therapeutic strategies for IBD, its associated mortality rate continues to rise, which is often attributed to unforeseen side effects of conventional treatments. In this context, we explored the potential of Ecklonia cava extract (ECE), derived from an edible marine alga known for its anti-inflammatory and antioxidant properties, in mitigating IBD. This study investigated the effectiveness of ECE as a preventive agent in a murine model of dextran sulfate sodium (DSS)-induced colitis. Our findings revealed that pretreatment with ECE significantly ameliorated colitis severity, as evidenced by increased colon length, reduced spleen weight, and histological improvements demonstrated by immunohistochemical analysis. Furthermore, ECE significantly attenuated the upregulation of inflammatory cytokines and mediators and the infiltration of immune cells known to be prominent features of colitis in mice. Notably, ECE alleviated dysbiosis of intestinal microflora and aided in the recovery of damaged intestinal mucosa. Mechanistically, ECE exhibited protective effects against pathogenic colitis by inhibiting the NLRP3/NF-κB pathways known to be pivotal regulators in the inflammatory signaling cascade. These compelling results suggest that ECE holds promise as a potential candidate for IBD prevention. It might be developed into a functional food for promoting gastrointestinal health. This research sheds light on the preventive potential of natural compounds like ECE in the management of IBD, offering a safer and more effective approach to combating this challenging disease.

Pontocerebellar Hypoplasia 7 with Novel Compound Heterozygous Variants of TOE1 in a Boy with Micropenis, Developmental Delay, and Ataxia: The First Korean Case Report.

Pontocerebellar hypoplasia (PCH) is a rare neurodegenerative disorder characterized by hypoplasia of the pons and cerebellum and global developmental delay. Among several PCH types, PCH7 is a characteristic type that manifests with not only brain lesions but also sexual developmental disorders. The causative gene, TOE1, encodes a protein involved in small ribonucleic acid maturation and processing. TOE1 mutation is associated with neuronal survival that causes hypoplasia of the cerebellum and pons. We report the case of a male patient with PCH7, developmental delay, ataxia, micropenis, and undescended testis. Genetic analysis revealed compound heterozygous missense variants (c.955C>T and c.533T>G) in the TOE1 gene.

Adult height in girls with central precocious puberty without gonadotropin-releasing hormone agonist treatment: a retrospective case-control study.

BACKGROUND: The primary aim of this study was to investigate the final adult height (FAH) of girls diagnosed with central precocious puberty (CPP) who were untreated. METHODS: We retrospectively analyzed the medical records of 36 girls diagnosed with CPP between 8 and 9 years of age who did not receive treatment, and 206 girls diagnosed with CPP within the same age range who received gonadotropin-releasing hormone (GnRH) agonist treatment. Midparental height (MPH), predicted adult height (PAH) obtained using height and bone age (BA) at the time of diagnosis (PAH for BA), and PAH obtained using the Bayley-Pinneau method (PAH by BP) were calculated. Additionally, height at the time of growth completion was compared with the predicted height. RESULTS: The FAHs were 160.71±4.56 cm in the untreated group and 159.31±4.26 cm in the treated group. In the untreated group, the FAH was 0.99±4.50 cm shorter than the MPH but 4.29±3.33 cm and 3.46±3.93 cm greater than the PAH for BA and PAH by BP, respectively. CONCLUSION: In children diagnosed with CPP between 8 and 9 years of age who were untreated, FAH was greater than PAH for BA and PAH by BP at the time of diagnosis, indicating that the prognosis of FAH was not poor. Therefore, for girls diagnosed with CPP, it is recommended to consider various conditions, such as pubertal onset, height at diagnosis, BA, peak luteinizing hormone level, predicted height, and speed of puberty, when deciding whether to administer GnRH agonists.

Stereochemical assignment of clerodane-type diterpenes from the fruits of Casearia grewiifolia and their ability to inhibit PCSK9 expression.

More than 20 natural products have been reported to modulate PCSK9-mediated cholesterol regulation, and small-molecule-derived proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors continue to be developed and identified. Here, twelve undescribed clerodane-type diterpenes (1-9 and 12-14) and two known compounds were isolated from the chloroform-soluble extract of the dried fruits of Casearia grewiifolia Vent. using a PCSK9 mRNA expression monitoring assay. Among the undescribed compounds, the stereochemistry of two diastereomeric grewiifolins A and B (1 and 2) were extensively elucidated using 2D Nuclear Overhauser Effect Spectroscopy (NOESY) experiments, excitation-sculptured indirect detection experiments (EXSIDE), interproton distance analyses, and computational calculations that included quantum chemical shift calculations combined with DP4+ analysis. All isolates were assessed for their inhibitory activity against PCSK9 and IDOL mRNA expression. Among the compounds tested, compound 3 inhibited PCSK9 and IDOL mRNA expression.

Drug repositioning of anti-microbial agent nifuratel to treat mast cell-mediated allergic responses.

Objectives: Our objective was to assess the effects and mechanisms of nifuratel on IgE-mediated mast cell (MC) degranulation and anaphylaxis in both in vitro and in vivo settings.Methods: The anti-allergic activity of nifuratel was evaluated in mast cell cultures and the passive cutaneous anaphylaxis (PCA) model. The effects of nifuratel on signaling pathways stimulated by antigen in mast cells were measured by immunoblotting, immunoprecipitation, in vitro protein tyrosine kinase assay, and other molecular biological methods.Results: Nifuratel reversibly inhibited antigen-induced degranulation of MCs (IC50, approximately 0.34 µM for RBL-2H3 cells; approximately 0.94 µM for BMMCs) and suppressed the secretion of inflammatory cytokines IL-4 (IC50, approximately 0.74 µM) and TNF-α (IC50, approximately 0.48 µM). Mechanism studies showed that nifuratel inhibited the phosphorylation of Syk by antigen via the inhibition of recruitment of cytosolic Syk to the É£ subunit of FcεRI, and decreased the activation of Syk downstream signaling proteins LAT, Akt, and MAPKs. Finally, nifuratel dose-dependently suppressed the IgE-mediated passive cutaneous anaphylaxis in mice (ED50, approximately 22 mg/kg).Conclusion: Our findings suggest that nifuratel inhibits pathways essential for the activation of mast cells to suppress anaphylaxis, thereby indicating that the anti-microbial drug, nifuratel, could be a potential drug candidate for IgE-mediated allergic disorders.

Clinical characteristics and outcomes in febrile infants aged 29-90 days with urinary tract infections and cerebrospinal fluid pleocytosis.

Introduction: Fever without a focus is a common reason for medical evaluations, hospitalizations, and the antimicrobial treatment of infants younger than 90 days. The presence of cerebrospinal fluid (CSF) pleocytosis could be challenge for clinicians who treat febrile young infants with urinary tract infection (UTI). We evaluated the factors associated with sterile CSF pleocytosis and the clinical outcomes of the patients. Methods: A retrospective review of patients aged 29-90 days with febrile UTIs who underwent a non-traumatic lumbar puncture (LP) at Pusan National University Hospital from January 2010 to December 2020 was conducted. CSF pleocytosis was defined as white blood cell (WBC) counts ≥9/mm3. Results: A total of 156 patients with UTI were eligible for this study. Four (2.6%) had concomitant bacteremia. However, no patients had culture-proven bacterial meningitis. In correlation analysis, although weak strength, CSF WBC counts were positively correlated with C-reactive protein (CRP) level (Spearman r = 0.234; P = 0.003). Thirty-three patients had CSF pleocytosis [21.2%; 95% confidential interval (CI), 15.5-28.2]. The time from fever onset to the hospital visit, peripheral blood platelet counts, and CRP level at admission were statistically significant in patients with sterile CSF pleocytosis compared to those without CSF pleocytosis. In the multiple logistic regression, only CRP was independently associated with sterile CSF pleocytosis (cutoff, 3.425 mg/dl; adjusted odds ratio, 2.77; 95% CI, 1.19-6.88). The proportion of fever defervescence by hospital day 2 was 87.9% in patients with CSF pleocytosis and 89.4% in those without CSF pleocytosis (P = 0.759). There was no statistical difference in the fever defervescence curves between the two patient groups (P = 0.567). No patients had neurological manifestations or complications. Conclusions: Coexisting sterile CSF pleocytosis among febrile infants with UTIs suggest a systemic inflammatory response. However, the clinical outcomes between the two groups were similar. A selective LP should be considered in young infants with evidence of UTI, and inappropriate antibiotic therapy for sterile CSF pleocytosis should be avoided.

Pellino 3 promotes the colitis-associated colorectal cancer through suppression of IRF4-mediated negative regulation of TLR4 signalling.

The incidence of colitis-associated colorectal cancer (CAC) has increased due to a high-nutrient diet, increased environmental stimuli and inherited gene mutations. To adequately treat CAC, drugs should be developed by identifying novel therapeutic targets. E3 ubiquitin-protein ligase pellino homolog 3 (pellino 3; Peli3) is a RING-type E3 ubiquitin ligase involved in inflammatory signalling; however, its role in the development and progression of CAC has not been elucidated. In this study, we studied Peli3-deficient mice in an azoxymethane/dextran sulphate sodium-induced CAC model. We observed that Peli3 promotes colorectal carcinogenesis with increased tumour burden and oncogenic signalling pathways. Ablation of Peli3 reduced inflammatory signalling activation at the early stage of carcinogenesis. Mechanistic studies indicate that Peli3 enhances toll-like receptor 4 (TLR4)-mediated inflammation through ubiquitination-dependent degradation of interferon regulatory factor 4, a negative regulator of TLR4 in macrophages. Our study suggests an important molecular link between Peli3 and colonic inflammation-mediated carcinogenesis. Furthermore, Peli3 can be a therapeutic target in the prevention and treatment of CAC.

Provider and client perspectives on the use of maternity waiting homes in rural Rwanda.

BACKGROUND: The World Health Organization recommends the implementation of maternity waiting homes (MWH) to reduce delays in access to obstetric care, particularly for high-risk pregnancies and mothers living far from health facilities, and as a result, several countries have rolled out MWHs. However, Rwanda has not implemented this recommendation on a large scale. There is only one MWH in the country, hence a gap in knowledge regarding the potential utilisation and benefits of MWHs. OBJECTIVE: To explore providers' and clients' perspectives on facilitators and barriers to the use of MWH in rural Rwanda. METHODS: We conducted a qualitative study to explore health providers' and clients' perspectives on facilitators and barriers to the use of MWH in Rwanda, between December 2020 and January 2021. We used key informant interviews and focus group discussions to collect data. Data were analysed using NVivo qualitative analysis software version 11. RESULTS: Facilitators included perceptions that the MWH offered either a peaceful and home-like environment, good-quality services, or timely obstetric services, and was associated with good maternal and neonatal outcomes. Barriers included limited awareness of the MWH among pregnant women, fear of health providers to operate the MWH at full capacity, women's lack of autonomy, uncertainty over funding for the MWH, and perceived high user fees. CONCLUSION: The Ruli MWH offers a peaceful environment for pregnant women while providing quality and timely obstetric care, resulting in positive maternal and neonatal outcomes for women. However, its existence and benefits are not widely known, and its use is limited due to inadequate resources. There is a need for increased awareness of the MWH among healthcare providers and the community, and lessons from this MWH could inform the scale up of MWHs in Rwanda.

Receiving antenatal care components and associated factors in Northwestern Tanzania.

INTRODUCTION: Tanzania had an estimated 5.400 maternal deaths in 2020. Suboptimal quality of antenatal care (ANC) presents a major challenge. It is not known what precisely the uptake of the various ANC components is, such as counseling on birth preparedness and complication readiness, preventive measures and screening tests. We assessed the level of receiving the various ANC components and associated factors in order to identify opportunities to improve ANC. METHODS: A cross-sectional household survey using a structured questionnaire through face-to-face interviews, was conducted in April 2016 in Mara and Kagera regions, Tanzania, applying a two-stage, stratified-cluster sampling design. The analysis included 1,162 women aged 15-49 years who attended ANC during their last pregnancy and had given birth not longer than two years prior to the survey. To account for inter- and intra-cluster variations, we used mixed-effect logistic regression to examine factors associated with receiving essential ANC components: counseling around birth preparedness and complication readiness (with presumed effects on knowledge about danger signs) and preventive measures. RESULTS: About In 878 (76.1%) women preparedness for birth and its complications was observed to exist. Overall counseling was low where 902 (77.6%) women received adequate counseling. Overall knowledge of danger signs was low in 467 women (40.2%). Uptake of preventive measures was low, with presumptive malaria treatment in 828 (71.3%) and treatment of intestinal worms in 519 (44.7%) women. Screening test levels varied for HIV in 1,057 (91.2%), any blood pressure measurement in 803 (70.4%), syphilis in 367 (32.2%) and tuberculosis in 186 (16.3%) women. After adjusting for age, wealth and parity, the likelihood of receiving adequate counseling on essential topics was less in women without education versus primary education (aOR 0.64; 95% CI 0.42-0.96) and in women who had <4 ANC visits versus ≥4 visits (aOR 0.57; 95% CI 0.40-0.81). Receiving care in privacy or not (aOR 2.01; 95% CI 1.30-3.12) and having secondary education as compared to primary education (aOR 1.92; 95% CI 1.10-3.70) were associated with receiving adequate counseling. Odds of receiving adequate care in at least one ANC visit were lower in women with joint decision making on major purchases versus decision making by male partner or other family members alone (aOR 0.44; 95% CI 0.24-0.78), similar to being less knowledgeable on danger signs (aOR 0.70; 95% CI 0.51-0.96). CONCLUSION: Overall uptake of various essential ANC components was low. Frequent ANC visits and ensuring privacy are all essential to improve the uptake of ANC.

Effect of gonadotropin-releasing hormone agonist treatment on near final height in girls with central precocious puberty and early puberty.

PURPOSE: The aim of this study was to examine whether gonadotropin-releasing hormone (GnRH) agonist treatment is effective in preserving final height in patients with central precocious puberty (CPP) or early puberty (EP). METHODS: The medical records of 40 patients with CPP and 206 patients with EP who completed GnRH agonist treatment following diagnosis were analyzed retrospectively. Height and height standard deviation (height SDS) scores based on bone age (BA) were measured and calculated at baseline, after treatment completion, and at final follow-up to compare changes within and between groups. Predicted adult height (PAH) was estimated by the height corresponding to height SDS for BA in girls at 18 years 11 months of age based on the growth chart. RESULTS: PAH at baseline did not differ significantly between the CPP group (153.67±4.95) and the EP group (154.77±3.72). In the CPP group, PAH significantly increased at treatment completion (156.01±4.61) and at final follow-up (158.52±6.04) compared to baseline. In the EP group, PAH significantly increased at treatment completion (157.7±3.60) and at final follow-up (159.31±4.26) compared to baseline. The increase in PAH at all timepoints compared to baseline did not significantly differ between the CPP and EP groups. CONCLUSION: Both CPP and EP groups had significantly greater PAH after treatment, with no difference in the amount of increase between groups. These results show that GnRH agonist treatment can help increase final height even in patients diagnosed with EP after the age of 8 years.

Anti-fibrotic effect of aurocyanide, the active metabolite of auranofin.

Drug repositioning has gained significant attention over the past several years. The anti-rheumatoid arthritis drug auranofin has been investigated for the treatment of other diseases, including liver fibrosis. Because auranofin is rapidly metabolized, it is necessary to identify the active metabolites of auranofin that have detectable levels in the blood and reflect its therapeutic effects. In the present study, we investigated whether aurocyanide as an active metabolite of auranofin, can be used to evaluate the anti-fibrotic effects of auranofin. Incubation of auranofin with liver microsomes showed that auranofin was susceptible to hepatic metabolism. Previously, we found that the anti-fibrotic effects of auranofin are mediated via system xc--dependent inhibition of the NOD-, LRR-, and pyrin domain-containing protein 3 (NLRP3) inflammasome. Therefore, we tried to identify active metabolites of auranofin based on their inhibitory effects on system xc- and NLRP3 inflammasome in bone marrow-derived macrophages. Among the seven candidate metabolites, 1-thio-ß-D-glycopyrano-sato-S-(triethyl-phosphine)-gold(I) and aurocyanide potently inhibited system xc- and NLRP3 inflammasome. A pharmacokinetics study on mice detected significant plasma levels of aurocyanide after auranofin administration. Oral administration of aurocyanide significantly prevented thioacetamide-induced liver fibrosis in mice. Moreover, the in vitro anti-fibrotic effects of aurocyanide were assessed in LX-2 cells, where aurocyanide significantly decreased the migratory ability of the cells. In conclusion, aurocyanide is metabolically stable and detectable in plasma, and has inhibitory effects on liver fibrosis, suggesting that it is a potential marker of the therapeutic effects of auranofin.
