Successful perinatal management of a woman with congenital factor XIII deficiency using recombinant factor XIII: A case report and literature review
Get PDFFactor XIII deficiency is an extremely rare autosomal recessive genetic disorder, occurring in 1 of 3-5 million people, and is associated with perinatal complications, such as habitual abortion and prolonged bleeding. Although plasma-derived factor XIII (Fibrogamin®) carries a risk of infection and contains very low concentrated forms of factor XIII (FXIII) used for a pregnant woman with congenital coagulation factor XIII deficiency, recombinant factor XIII (rFXIII, Novo Thirteen®; Tretten®, Novo Nordisk, Bagsvaerd, Denmark), which has no risk of infection and is highly concentrated, has emerged as a novel formulation. Herein, we report the first case of a Japanese pregnant woman with congenital coagulation factor XIII deficiency successfully managed by rFXIII. She had a good perinatal course without pregnancy-related complications and transfusion through the perinatal period.journal articl
SARS-CoV-2 induces inflammation and intracranial infection through the olfactory epithelium-olfactory bulb pathway in non-human primates
Get PDFWe examined the histopathological changes in the olfactory mucosa of cynomolgus and rhesus macaque models of SARS-CoV-2 infection. SARS-CoV-2 infection induced severe inflammatory changes in the olfactory mucosa. A major histocompatibility complex (MHC) class II molecule, HLA-DR was expressed in macrophage and supporting cells, and melanocytes were increased in olfactory mucosa. Supporting cells and olfactory neurons were infected, and SARS-CoV-2 N protein was detected in the axons of olfactory neurons and in olfactory bulbs. Viral RNA was detected in olfactory bulbs and brain tissues. The olfactory epithelium-olfactory bulb pathway may be important as a route for intracranial infection by SARS-CoV-2.journal articl
Alcohol Consumption and Cerebral Small- and Large-Vessel Diseases: A Mendelian Randomization Analysis
Get PDFAims:
It remains inconclusive regarding alcohol intake and stroke risk because determining risk factors depends on the specific pathogenesis of stroke. We used the variant rs671 in the aldehyde dehydrogenase 2 gene (ALDH2) as an instrument to investigate the causal role of alcohol intake in cerebral small- and large-vessel diseases.
Methods:
We studied 682 men (mean age, 70.0 years), without stroke, in a cross-sectional Mendelian randomization analysis. We assessed small-vessel diseases (SVDs), which comprised lacunar infarcts, white matter hyperintensities (WMHs), and cerebral microbleeds, and large intracranial artery stenosis (ICAS) on brain magnetic resonance imaging.
Results:
The median (25%tiles, 75%tiles) alcohol consumption by ALDH2-rs671 inactive A allele (n=313 [45.9%]) and non-A allele (n=369 [54.1%]) carriers was 3.5 (0.0, 16.0) and 32.0 (12.9, 50.0) g/day, respectively. Non-A allele carriers had higher prevalent hypertension and lower low-density lipoprotein cholesterol concentrations than A allele carriers. In age-adjusted ordinal logistic regression for graded burden, odds ratios (95% confidence intervals) for total SVDs, lacunar infarcts, WMHs, cerebral microbleeds, and ICAS in non-Aallele carriers were 1.46 (1.09-1.94), 1.41 (0.95-2.08), 1.39 (1.05-1.85), 1.69 (1.06-2.69), and 0.70 (0.50-0.98), respectively, compared with A allele carriers. These associations attenuated to statistical non-significance after considering covariates and amount of alcohol intake.
Conclusions:
Our findings suggest a positive association of alcohol consumption with risk of cerebral SVDs and its inverse association with risk of large-vessel disease through intermediaries, such as hypertension or low-density lipoprotein cholesterol. These findings provide insight into potential causal mechanisms linking alcohol consumption with stroke risk.journal articl
Management of Pregnant Women with Mental Disorders Requires Attention to Gestational Diabetes Mellitus
Get PDFBackground:
Psychiatric interventions may be required during pregnancy. In the aspect of the management of psychiatric symptoms and the consideration of the need for pharmacotherapy, possibly to manage the effects on the fetus, pregnant women with mental disorders are considered high risk as other physical illnesses.
Objective:
We investigated the characteristics of pregnant women with psychiatric disorders compared with high-risk pregnant women with physical illnesses at our university hospital and the effects of psychotropic drug use on pregnant women with mental disorders and their children.
Materials and methods:
In a multivariate analysis of 1282 pregnant women, excluding those with multiple pregnancies who gave birth at our hospital between January 2017 and the end of December 2019, we evaluated the effects of mental disorders and the use of psychotropic drugs throughout at least the third trimester up to the day of delivery on obstetric complications and infants. All data were collected retrospectively.
Results:
Ninety-nine pregnant women had mental disorders and 62 took psychotropic drugs. Among multiple factors, pregnant women with mental disorders were associated with significantly higher rates of smoking and gestational diabetes mellitus (GDM) and significantly lower child abnormalities. The cause or effect was difficult to determine; however, the use of antipsychotics or antidepressants was also significantly associated with GDM, while psychotropic use was not related to any of the other factors investigated in this study.
Conclusions:
Attention to GDM might be important in the management of pregnant women with mental disorders.journal articl
Relationship between perfectionism, overactivity, pain severity, and pain interference in individuals with chronic pain: A cross-lagged panel model analysis
Get PDFObjectives:
Overactivity is a characteristic of individuals with chronic pain. Previous cross-sectional studies demonstrated a relationship between perfectionism and overactivity. Therefore, the present study used a longitudinal design to determine whether pain severity and pain interference were exacerbated by overactivity and whether overactivity was exacerbated by perfectionism.
Methods:
Participants with chronic pain were recruited using crowdsourcing. The participants completed the questionnaires at three time points: T1, T2, and T3 (September, October, and November 2021, respectively). The questionnaire assessed overactivity, perfectionistic strivings, perfectionistic concerns, pain severity, and pain interference. We created cross-lagged panel models to examine the hypothesized relationships among pain, overactivity, and perfectionism.
Results:
After excluding ineligible participants and invalid response sets, we analyzed the questionnaires completed by 666 participants at T1, 560 at T2, and 554 at T3. The average duration of chronic pain at T1 was 36.35 ± 53.53 months. Perfectionistic strivings were partially linked to overactivity, and pain interference was partially related to overactivity. Contrary to our expectations, overactivity did not predict pain severity or pain interference.
Conclusions:
The hypotheses that perfectionism exacerbates overactivity and that overactivity exacerbates pain severity and pain interference were not supported. These results may have been affected by the quality of the assessment of overactivity. Therefore, further research with a refined evaluation of overactivity is required.journal articl
