Antidepressant discontinuation before or during pregnancy and risk of psychiatric emergency in Denmark: A population-based propensity score–matched cohort study

Background Women prescribed antidepressants face the dilemma of whether or not to continue their treatment during pregnancy. Currently, limited evidence is available on the efficacy of continuing versus discontinuing antidepressant treatment during pregnancy to aid their decision. We aimed to estimate whether antidepressant discontinuation before or during pregnancy was associated with an increased risk of psychiatric emergency (ascertained by psychiatric admission or emergency room visit), a proxy measure of severe exacerbation of symptoms/mental health crisis. Methods and findings We carried out a propensity score–matched cohort study of women who gave birth to live-born singletons between January 1, 1997 and June 30, 2016 in Denmark and who redeemed an antidepressant prescription in the 90 days before the pregnancy, identified by Anatomical Therapeutic Chemical (ATC) code N06A. We constructed 2 matched cohorts, matching each woman who discontinued antidepressants before pregnancy (N = 2,669) or during pregnancy (N = 5,467) to one who continued antidepressants based on propensity scores. Maternal characteristics and variables related to disease severity were used to generate the propensity scores in logistic regression models. We estimated hazard ratios (HRs) of psychiatric emergency in the perinatal period (pregnancy and 6 months postpartum) using stratified Cox regression. Psychiatric emergencies were observed in 76 women who discontinued antidepressants before pregnancy and 91 women who continued. There was no evidence of higher risk of psychiatric emergency among women who discontinued antidepressants before pregnancy (cumulative incidence: 2.9%, 95% confidence interval [CI]: 2.3% to 3.6% for discontinuation versus 3.4%, 95% CI: 2.8% to 4.2% for continuation; HR = 0.84, 95% CI: 0.61 to 1.16, p = 0.298). Overall, 202 women who discontinued antidepressants during pregnancy and 156 who continued had psychiatric emergencies (cumulative incidence: 5.0%, 95% CI: 4.2% to 5.9% versus 3.7%, 95% CI: 3.1% to 4.5%). Antidepressant discontinuation during pregnancy was associated with increased risk of psychiatric emergency (HR = 1.25, 95% CI: 1.00 to 1.55, p = 0.048). Study limitations include lack of information on indications for antidepressant treatment and reasons for discontinuing antidepressants. Conclusions In this study, we found that discontinuing antidepressant medication during pregnancy (but not before) is associated with an apparent increased risk of psychiatric emergency compared to continuing treatment throughout pregnancy.
Triploid genetic algorithm for convolutional neural network–based diagnosis of mild cognitive impairment

The diagnosis of mild cognitive impairment (MCI), which is deemed a formative phase of dementia, may greatly assist clinicians in delaying its headway toward dementia. This article proposes a deep learning approach based on a triploid genetic algorithm, a proposed variant of genetic algorithms, for classifying MCI converts and non‐converts using structural magnetic resonance imaging data. It also explores the effect of the choice of activation functions and that of the selection of hyper‐parameters on the performance of the model. The proposed work is a step toward automated convolutional neural networks. The performance of the proposed method is measured in terms of accuracy and empirical studies exhibit the preeminence of our proposed method over the existing ones. The proposed model results in a maximum accuracy of 0.97961. Thus, it may contribute to the effective diagnosis of MCI and may prove important in clinical settings.
Apolipoprotein E polymorphism ε4‐stratified longitudinal association between daytime naps, sleep apnea and mild cognitive impairment: A prospective cohort study

Sleep characteristics, including taking a nap and sleep apnea, have been proven to have effects on cognitive function, and apolipoprotein E polymorphism ε4 (APOEε4) has been confirmed to be a risk factor for mild cognitive impairment (MCI), but epidemiological studies linking sleep characteristics and APOEε4 are scarce. We aimed to explore the longitudinal association between sleep characteristics and MCI in an overall cohort, in APOEε4 carriers and in APOEε4 non‐carriers.
5-fluorouracil suppresses stem cell-like properties by inhibiting p38 in pancreatic cancer cell line PANC-1.

INTRODUCTION Suppressing the phenotype of cancer stem cells (CSCs) is a promising treatment strategy for cancer. P38 mitogen-activated protein kinases (MAPK, p38) play an important role in the occurrence, development, and stemness maintenance of tumors. The aim of the current study is to investigate the effect of p38 on the stemness maintenance of CSCs in pancreatic cancer cell line PANC-1. MATERIAL AND METHODS PANC-1 human pancreatic cancer cells were treated with 5-fluorouracil (5-FU) at 0.5 IC50, IC50, and 2 IC50 for 24 h. PANC-1 cells were treated for 24 h with 5-FU at 0.5IC50, IC50, and 2IC50 with or without VX-702, p38 phosphorylation inhibitor. Cells were resuspended in DMEM supplemented with 20 ng/ml epidermal growth factor, 2% B27, 5 mg/ml insulin, 20 g/ml basic fibroblast growth factor, and 10 µg/ml transferrin. Cells were seeded in ultra-low adhesion 6-well dishes to observe tumor spheroidization. The expression of CDK2, cyclin B1, cyclin D1, OCT4, SOX2, Nanog, and p38 was measured by Western blot. The mRNA expression of p38, OCT4, Nanog, and SOX2 was measured by RT-PCR. Flow cytometry was performed to evaluate the cell cycle, apoptosis, and proportion of CD44+CD133+ PANC-1 cells. RESULTS 5-FU decreased cell viability and increased apoptosis. 5-FU suppressed the stemness maintenance of CSCs in PANC-1 cells, as demonstrated by the inhibition of tumorsphere formation, the decrease in CD44+CD133+ cells' fraction, and downregulation of OCT4, Nanog, and SOX2 expression. In addition, 5-FU inhibited the phosphorylation of p38 in PANC-1 cells. The phosphorylation of p38 was subsequently suppressed by VX-702, p38 mitogen-activated protein kinase inhibitor, which exhibited similar effects as those of 5-FU treatment. The effect of VX-702 on PANC-1 cells was further enhanced by 5-FU treatment. Thus, p38 inhibitor decreased the viability and increased the apoptosis of PANC-1 cells. P38 inhibitor suppressed the stemness maintenance of CSCs in PANC-1 cells, as demonstrated by the inhibition of tumorsphere formation, the decrease in CD44+CD133+ cells, and the downregulation of OCT4, Nanog, and SOX2 expression. CONCLUSIONS These findings indicate that the inhibition of p38 phosphorylation suppresses the stemness maintenance and 5-FU resistance of PANC-1 cells, providing a potential therapeutic target for the prevention and treatment of pancreatic cancer.
Real-world indoor mobility with simulated prosthetic vision: The benefits and feasibility of contour-based scene simplification at different phosphene resolutions

Neuroprosthetic implants are a promising technology for restoring some form of vision in people with visual impairments via electrical neurostimulation in the visual pathway. Although an artificially generated prosthetic percept is relatively limited compared with normal vision, it may provide some elementary perception of the surroundings, re-enabling daily living functionality. For mobility in particular, various studies have investigated the benefits of visual neuroprosthetics in a simulated prosthetic vision paradigm with varying outcomes. The previous literature suggests that scene simplification via image processing, and particularly contour extraction, may potentially improve the mobility performance in a virtual environment. In the current simulation study with sighted participants, we explore both the theoretically attainable benefits of strict scene simplification in an indoor environment by controlling the environmental complexity, as well as the practically achieved improvement with a deep learning-based surface boundary detection implementation compared with traditional edge detection. A simulated electrode resolution of 26 × 26 was found to provide sufficient information for mobility in a simple environment. Our results suggest that, for a lower number of implanted electrodes, the removal of background textures and within-surface gradients may be beneficial in theory. However, the deep learning-based implementation for surface boundary detection did not improve mobility performance in the current study. Furthermore, our findings indicate that, for a greater number of electrodes, the removal of within-surface gradients and background textures may deteriorate, rather than improve, mobility. Therefore, finding a balanced amount of scene simplification requires a careful tradeoff between informativity and interpretability that may depend on the number of implanted electrodes.
Bacterial cell-wall quantification by a modified low volume Nelson-Somogyi method and its use with different sugars.

The study of peptidoglycan binding proteins frequently requires in vitro binding assays in which the isolated peptidoglycan used as substrate has to be carefully quantified. Here we describe an easy and sensitive assay for the quantification of peptidoglycan based on a modified Nelson-Somogyi reducing sugar assay. We report the response of this assay to different common sugars and adapt its use to peptidoglycan samples that have been subjected to acid hydrolysis. This method showed a better sensitivity than the peptidoglycan quantification method based on the acid detection of diaminopimelic acid. The method described in this work besides being valuable in the characterization of peptidoglycan binding proteins, is also useful for quantification of reducing monosaccharides or of polysaccharides after acid or hydrolysis.
Variables associated with methamphetamine use within the past year and sex differences among patients with methamphetamine use disorder: A cross-sectional study in Japan.

BACKGROUND AND OBJECTIVES Methamphetamine use disorder is the most common reason for psychiatrist visits among illicit drug users in Japan. Although variables associated with methamphetamine use and sex differences have been reported in the United States, Australia, and Asian countries, such studies are rare in Japan. We examined methamphetamine use within the past year among patients receiving treatment by sex and proposed important treatment targets. METHODS This cross-sectional study analyzed the Nationwide Mental Hospital Survey on Drug-related Psychiatric Disorders. We divided 1086 men and 376 women into two groups according to methamphetamine use within the past year and conducted log-binomial regression analyses by sex to examine the variables associated with methamphetamine use. For methamphetamine users, the source was identified. RESULTS Women were more likely to obtain methamphetamine from their friends, acquaintances, family members, or partners than men. Multivariable regression analysis showed that younger age in both sexes and higher educational attainment (prevalence ratio [PR] = 1.29; 95% confidence interval [CI] = 1.06-1.57) and employment (PR = 1.26; 95% CI = 1.05-1.51) were associated with methamphetamine use in men. Age-adjusted regression analysis showed that the variables associated with methamphetamine use were comorbid alcohol abuse and cannabis abuse in women and benzodiazepine abuse in both sexes. CONCLUSION AND SCIENTIFIC SIGNIFICANCE In women, in particular, the surrounding relationships related to methamphetamine might be considered treatment targets. Young and working patients might need more accessible outpatient clinics and treatment programs. Comorbid substance abuse should be assessed and treated.
Postoperative Sedation Duration as an Independent Risk Factor for Postoperative Pneumonia in Head and Neck Cancer Patients Undergoing Free Flap Reconstruction

Objective Patients who had reconstruction for head and neck cancer usually have long duration of postoperative sedation and intensive care. This is due to the complex nature of large-area soft tissue defect surgeries and upper respiratory tract infections associated with them. Postoperative pulmonary complications are common in these patients. In this study, we analyzed the risk factors and the relationship between postoperative complications and the duration of sedation to improve the patients' recovery process after free flap reconstruction for head and neck surgery. Materials and Methods This was a retrospective study that included 188 patients who had head and neck surgery with free flap reconstruction in 2011 (traditional recovery group) and 2018 (early recovery group). Postoperative recovery events were compared between the 2 groups. Complications such as pneumonia, wound infection, vascular thrombosis, and bleeding were also analyzed. Results The results showed that the early recovery group had a shorter duration of sedation (P < 0.001), shorter duration of intensive care unit stay (P = 0.05), more rapid ventilator weaning (P < 0.001), and fewer pneumonia events (8.8% vs 39.1%) than the traditional recovery group. Wound- and vessel-related complications were not affected by the duration of sedation. Conclusions Our study demonstrated that shortening the duration of postoperative sedation can effectively decrease the length of intensive care unit stay and reduce postoperative incidence of pneumonia without increasing wound- and vessel-related complications.
The essential differences in microbial and chemical components of musk of different qualities secreted by captive male forest musk deer (Moschus berezovskii)

Musk is a precious raw material and ingredient in Chinese traditional medicine. The production of unqualified musk has become a puzzling problem in forest musk deer (FMD) breeding. However, what the essential differences between so‐called unqualified musk and mature qualified musk have not yet been elucidated. In this study, 12 musk samples were collected and separated into two groups according to their external properties. One group is white or black cream‐like secretion with sour or unpleasant odour (MM); the other group is brown or blackish brown solid secretion with pleasant fragrance (DM). Next‐generation sequencing and gas chromatography‐mass spectrometry were used to explore the essential differences between the DM and MM groups in microbial and chemical compositions. The results indicate that the DM group has more heterogenous microbial structure but simpler relationships among microbial communities. LEfSe analysis showed that 14 taxa at the genus level could be used to distinguish the DM and MM groups and Bacillus, Paracoccus, tenoteophomonas, Mycobacterium and Leuconostoc were more abundant in the DM group (P < 0.05). In addition, six compounds were identified to specifically distinguish the DM and MM groups under the OPLS‐DA model. PICRUSt analysis revealed that metabolic pathways such as carbohydrate metabolism, nucleotide metabolism, energy metabolism, transport and catabolism were enriched in the DM group. All these findings of differences in microbiota and chemical compositions would provide potential clues for MM quality improvement and new evidence for the scientific establishment of a quality evaluation standard for musk.
Association of urinary angiotensinogen with renal arteriolar remodeling in chronic kidney disease

Objective: Renin–angiotensin system (RAS) might be associated with arteriolar remodeling. The present study aimed to explore the hitherto unknown relationship between renal RAS and renal arteriolar remodeling and to elucidate whether altered renal RAS subsequently affects renal function in patients with chronic kidney disease (CKD). Methods: In this retrospective study, patients with various CKDs not using RAS inhibitors who underwent renal biopsy were included in cross-sectional and longitudinal analyses. Urinary angiotensinogen (UAGT) levels and wall/lumen ratio (WLR) were determined to evaluate renal RAS and renal arteriolar remodeling, respectively. The association between ln(UAGT) and ln(WLR) was cross-sectionally examined using a liner regression model. Furthermore, the association of ln(UAGT) with subsequent changes in estimated glomerular filtration rate (eGFR) per year were longitudinally examined in the largest subgroup of patients who were diagnosed with IgA nephropathy. Results: In the overall cohort (n = 54), the median age, blood pressures, eGFR, and WLR were 37 years, 120/73 mmHg, 85 ml/min per 1.73 m2, and 0.93, respectively. Ln(UAGT) was significantly and positively associated with ln(WLR) even after adjusting for classical and nonclassical clinical renal risk factors. In patients with IgA nephropathy, higher ln(UAGT) was associated with higher ln(WLR). Ln(UAGT) also tended to be associated with a greater decline in eGFR per year over a median period of 8.7 years, even after adjusting for potential confounding factors. Conclusion: In patients with CKD, renal RAS might be associated with renal arteriolar remodeling and future decline in eGFR, independent of potential risk factors.
Does Cyberchondria Mediate the Effect of COVID-19 Fear on the Stress?

ABSTRACT To determine the effect of COVID-19 fear on the stress of the individuals, and to investigate the mediating role of cyberchondria on this effect. The population of the present study consisted of the individuals 18 years of age or older who were resident in the Bursa province of Turkey. The research enrolled 425 individuals who agreed to complete the questionnaire. The questionnaire, which consists of four sections including, (1) sociodemographic characteristics; (2) fear of COVID-19 scale; (3) short cyberchondria scale; and (4) perceived stress scale, was used to collect data in the study. Descriptive statistical methods and path analysis were used for data analysis. Fear of COVID-19 has a significant effect on perceived stress/distress which is mediated by cyberchondria. However, fear of COVID-19 does not have a significant effect on perceived insufficient self-efficacy. Similarly, cyberchondria does not have a mediating role in this effect. Reliable and accurate information resources should be presented about COVID-19; the individuals should adopt behaviors that would improve their health; and getting professional help should be encouraged for those with psychological problems. Otherwise, fear of COVID-19 causes perceived stress/distress to the individuals.
Translation and validation of the “personal evaluation of transitions in treatment (PETIT)” scale for people with schizophrenia

TRANSLATION AND VALIDATION OF THE "PERSONAL EVALUATION OF TRANSITIONS IN TREATMENT (PETIT)" SCALE FOR SCHIZOPHRENIC POPULATION Aims. To adapt the 'Personal Evaluation of Transitions in Treatment (PETIT)' scale into Spanish and analyse its psychometric properties on schizophrenic population. Method. 223 patients in outpatient treatment diagnosed with schizophrenia according to DSM-5 criteria participated in the study. A defined variable 'therapeutic compliance', DA110 and SMAQ were used as a gold standard and the psychometric properties of the scale were analysed at three time points (baseline, 1 month and 6 months). Results. The scale has very high face (or logical) validity. Exploratory factor analysis showed it would be necessary to eliminate item 7. The reliability of the scale is high (Cronbach's alpha = 0.91), demonstrating good internal consistency. After eliminating item 7, confirmatory factor analysis obtained 5 components that explained 57,76% of the variance. The content of the scale is valid for discriminating between patients of different treatment adherence, response and quality of life. The cut-off point of the 'PETIT' scale in Spanish is set at 24 points for both sexes, with good sensibility to change and very good concordance force over the three time points evaluated. Conclusions. After eliminating item 7 and using '24' as cut-off point, the 'PETIT' scale was able to detect changes in both adherence and response to treatment as well as the resulting modifications to the quality of life of patients. Its use as a single instrument to measure all of the above makes it advisable for use in clinical practice, as the evaluation methods it requires are relatively simple and quick to perform.
Usability, acceptability, and feasibility of a High-Density Microarray Patch (HD-MAP) applicator as a delivery method for vaccination in clinical settings

ABSTRACT Background High-density microarray patch (HD-MAP) vaccines may increase vaccine acceptance and use. We aimed to ascertain whether professional immunizers (PIs) and other healthcare workers (HCWs) in Australia, a High-Income Country (HIC), found the HD-MAP applicator usable and acceptable for vaccine delivery. Methods This feasibility study recruited PIs and HCWs to administer/receive simulated HD-MAP administration, including via self-administration. We assessed usability against essential and desirable criteria. Participants completed a survey, rating their agreement to statements about HD-MAP administration. A subset also participated in an interview or focus group. Survey data were analyzed using descriptive statistics, and interviews were transcribed and subject to thematic analysis. Results We recruited 61 participants: 23 PIs and 38 HCWs. Findings indicated high usability and acceptability of HD-MAP use across both groups by a healthcare professional or trained user and for self-administration with safety measures in place. Most administrations met essential criteria, but PIs, on average, applied the HD-MAP for slightly less time than the required 10-seconds, which the HCWs achieved. PIs perceived safety concerns about home administration but found layperson self-administration acceptable in an emergency, pandemic, and rural or remote settings. Conclusions Participants found HD-MAP administration usable and acceptable. Usability and acceptability are likely to be improved through end-user education and training. Plain language summary Professional immunizers and healthcare workers found high-density microarray patch devices highly usable and acceptable to administer vaccines. HD-MAPs may have advantages over intramuscular injections in clinical settings and in pandemics. Vaccination with HD-MAP may improve acceptance for those with needle-related anxiety.
