An online self-guided cognitive intervention for unwanted intrusive thoughts about harming infants in new parents: initial randomised controlled trial with mediation analysis

Cogn Behav Ther. 2023 Jul 3:1-18. doi: 10.1080/16506073.2023.2229015. Online ahead of print.

ABSTRACT

Approximately one-fifth of new parents struggle with unwanted intrusive thoughts (UITs) about intentionally harming their child. This study evaluated the initial efficacy, feasibility and acceptability of a novel online self-guided cognitive intervention for new parents with distressing UITs. Self-recruited parents (N = 43, 93% female, age 23-43 years) of children 0-3 years reporting daily distressing and impairing UITs were randomized to the 8-week self-guided online cognitive intervention or to waiting-list. The primary outcome was change on the Parental Thoughts and Behaviour Checklist (PTBC) from baseline to week 8 (post-intervention). The PTBC and negative appraisals (mediator) were assessed at baseline, weekly, post-intervention and at the 1-month follow-up. Results showed that the intervention led to statistically significant reductions in distress and impairment associated with UITs at post-intervention (controlled between-group d = 0.99, 95% CI 0.56 to 1.43), which were maintained at the 1-month follow-up (controlled between-group d = 0.90, 95% CI 0.41 to 1.39). The intervention was deemed to be feasible and acceptable by the participants. Change in negative appraisals mediated reductions in UITs but the model was sensitive to mediator-outcome confounders. We conclude that this novel online self-guided cognitive intervention can potentially reduce the distress and impairment associated with UITs in new parents. Large-scale trials are warranted.Abbreviations: UITs: Unwanted Intrusive Thoughts PTBC: Parental Thoughts and Behaviour Checklist.

Efficacy of a continuously active disinfectant wipe on the environmental bioburden in the intensive care unit: A randomized controlled study

Infect Control Hosp Epidemiol. 2023 Jul 3:1-8. doi: 10.1017/ice.2023.111. Online ahead of print.

ABSTRACT

OBJECTIVE: To evaluate the efficacy of a new continuously active disinfectant (CAD) to decrease bioburden on high-touch environmental surfaces compared to a standard disinfectant in the intensive care unit.

DESIGN: A single-blind randomized controlled trial with 1:1 allocation.

SETTING: Medical intensive care unit (MICU) at an urban tertiary-care hospital.

PARTICIPANTS: Adult patients admitted to the MICU and on contact precautions.

INTERVENTION: A new CAD wipe used for daily cleaning.

METHODS: Samples were collected from 5 high-touch environmental surfaces before cleaning and at 1, 4, and 24 hours after cleaning. The primary outcome was the mean bioburden 24 hours after cleaning. The secondary outcome was the detection of any epidemiologically important pathogen (EIP) 24 hours after cleaning.

RESULTS: In total, 843 environmental samples were collected from 43 unique patient rooms. At 24 hours, the mean bioburden recovered from the patient rooms cleaned with the new CAD wipe (intervention) was 52 CFU/mL, and the mean bioburden was 92 CFU/mL in the rooms cleaned the standard disinfectant (control). After log transformation for multivariable analysis, the mean difference in bioburden between the intervention and control arm was -0.59 (95% CI, -1.45 to 0.27). The odds of EIP detection were 14% lower in the rooms cleaned with the CAD wipe (OR, 0.86; 95% CI, 0.31-2.32).

CONCLUSIONS: The bacterial bioburden and odds of detection of EIPs were not statistically different in rooms cleaned with the CAD compared to the standard disinfectant after 24 hours. Although CAD technology appears promising in vitro, larger studies may be warranted to evaluate efficacy in clinical settings.

Effect of curcumin on inflammatory biomarkers and iron profile in patients with premenstrual syndrome and dysmenorrhea: A randomized controlled trial

Physiol Rep. 2023 Jul;11(13):e15763. doi: 10.14814/phy2.15763.

ABSTRACT

Premenstrual syndrome (PMS) and primary dysmenorrhea are common gynecological problems and inflammation may have a role in their etiology. Curcumin is a polyphenolic natural product for which there is increasing evidence of anti-inflammatory and iron chelation effects. This study assessed the effects of curcumin on inflammatory biomarkers and iron profile in young women with PMS and dysmenorrhea. A sample of 76 patients was included in this triple-blind, placebo-controlled clinical trial. Participants were randomly allocated to curcumin (n = 38) and control groups (n = 38). Each participant received one capsule (500 mg of curcuminoid+ piperine, or placebo) daily, from 7 days before until 3 days after menstruation for three consecutive menstrual cycles. Serum iron, ferritin, total iron-binding capacity (TIBC) and high-sensitivity C-reactive protein (hsCRP), as well as white blood cell, lymphocyte, neutrophil, platelet counts, mean platelet volume (MPV) and red blood cell distribution width (RDW), were quantified. Neutrophil: lymphocyte ratio (NLR), platelet: lymphocyte ratio (PLR), and RDW: platelet ratio (RPR) were also calculated. Curcumin significantly decreased the median (interquartile range) serum levels of hsCRP [from 0.30 mg/L (0.0-1.10) to 0.20 mg/L (0.0-1.3); p = 0.041] compared with placebo, but did not show any difference for neutrophil, RDW, MPV, NLR, PLR and RPR values (p > 0.05). The treatment schedule was well-tolerated, and none of markers of iron metabolism statistically changed after the intervention in the curcumin group (p > 0.05). Curcumin supplementation may have positive effects on serum hsCRP, a marker of inflammation, with no any changes on iron homeostasis in healthy women with PMS and dysmenorrhea.

Maternal Knowledge of Oral Health During Pregnancy and Childbirth

Matern Child Health J. 2023 Jul 2. doi: 10.1007/s10995-023-03697-2. Online ahead of print.

ABSTRACT

OBJECTIVE: This cohort study was to investigate maternal knowledge of the oral health of woman and children during pregnancy and after childbirth, and the associated factors.

METHODS: Groups of women participating in a public prenatal dental care programme in Brazil were assessed, in two different stages. In the first stage, pregnant women were assessed for their own oral health. In the second stage, after childbirth, women were assessed for the oral health of their child. The examiner assigned a maternal knowledge score to the questionnaires, considering the ideal alternatives within the context of oral health promotion as correct answers. Statistical analysis included the Kruskal-Wallis and multiple linear regression tests, considering a level of significance of P < 0.05.

RESULTS: Ninety-eight women were included in the study, with a mean age 26.27 years (SD 6.51). In the regression analysis, the maternal knowledge score was associated with the presence of myths about oral health (P < 0.01), the children first dental appointment in the first year of life (P = 0.07), the presence of a non-nutritious sucking habit (P < 0.01), considering dental treatment to be important during pregnancy (P < 0.01), and having been instructed on oral health during pregnancy (P < 0.01) and after the children birth (P = 0.02).

CONCLUSION: This study suggests that the women showed a regular score of knowledge about their oral health and that of their children, as they still believed in some myths about oral health and the risks of dental treatment during pregnancy. Women who received guidance on oral health in pregnancy and after birth showed higher knowledge of their oral health and that of their children, demonstrating the importance of carrying out health promotion actions during pregnancy and the first years of the child’s life.

The effect of ultrasonic vibration protocols for cast post removal on the incidence of root dentin defects

J Oral Sci. 2023;65(3):190-194. doi: 10.2334/josnusd.23-0048.

ABSTRACT

PURPOSE: To investigate the effects of two ultrasonic vibration protocols for cast post removal (single or double ultrasound units) on the development of defects in root dentin.

METHODS: Sixty bovine incisors were selected. Fifteen roots were left unprepared (control). Forty-five roots were instrumented and filled. A 10-mm post space was prepared using #1-4 Largo drills. Fifteen teeth were prepared for post space and received no further procedure. Thirty roots had cast posts cemented and were submitted to ultrasonic vibration protocols for removal. The time necessary to remove each post was recorded. Roots were sectioned 3, 6, 9, and 12 mm from the coronal portion and viewed through a 25× magnification in a stereomicroscope. The presence of root fractures, partial cracks, and craze lines was registered. Chi-square and Fisher’s exact tests were performed to compare the incidence of dentin defects. The Kruskal-Wallis test was performed to explore the difference between the time needed for post removal. The significance level was set at P = 0.05.

RESULTS: Root defects were observed in all experimental groups. There were no statistical differences comparing previous root canal treatment and post removal steps, either with 1 or 2 ultrasonic units, in the formation of defects (P = 0.544) or fractures (P = 0.679).

CONCLUSION: Ultrasonic vibration protocols for removing cast posts did not increase the number of dentin defects compared to root canal preparation and obturation and post space preparation steps.

Evaluation and prediction of individual growth trajectories

Ann Hum Biol. 2023 Feb;50(1):247-257. doi: 10.1080/03014460.2023.2190619.

ABSTRACT

BACKGROUND: Conventional growth charts offer limited guidance to track individual growth.

AIM: To explore new approaches to improve the evaluation and prediction of individual growth trajectories.

SUBJECTS AND METHODS: We generalise the conditional SDS gain to multiple historical measurements, using the Cole correlation model to find correlations at exact ages, the sweep operator to find regression weights and a specified longitudinal reference. We explain the various steps of the methodology and validate and demonstrate the method using empirical data from the SMOCC study with 1985 children measured during ten visits at ages 0-2 years.

RESULTS: The method performs according to statistical theory. We apply the method to estimate the referral rates for a given screening policy. We visualise the child’s trajectory as an adaptive growth chart featuring two new graphical elements: amplitude (for evaluation) and flag (for prediction). The relevant calculations take about 1 millisecond per child.

CONCLUSION: Longitudinal references capture the dynamic nature of child growth. The adaptive growth chart for individual monitoring works with exact ages, corrects for regression to the mean, has a known distribution at any pair of ages and is fast. We recommend the method for evaluating and predicting individual child growth.

At-Home Versus Onsite COVID-19 School-based Testing: A Randomized Noninferiority Trial

Pediatrics. 2023 Jul 1;152(Suppl 1):e2022060352F. doi: 10.1542/peds.2022-060352F.

ABSTRACT

OBJECTIVES: Equitable access to coronavirus 2019 (COVID-19) screening is important to reduce transmission and maintain in-person learning for middle school communities, particularly in disadvantaged schools. Rapid antigen testing, and at-home testing in particular, could offer substantial advantages over onsite testing from a school district’s perspective, but it is unknown if engagement in at-home testing can be initiated and sustained. We hypothesized that an at-home COVID-19 school testing program would be noninferior to an onsite school COVID-19 testing program with regard to school participation rates and adherence to a weekly screening testing schedule.

METHODS: We enrolled 3 middle schools within a large, predominantly Latinx-serving, independent school district into a noninferiority trial from October 2021 to March 2022. Two schools were randomized to onsite and 1 school to at-home COVID-19 testing programs. All students and staff were eligible to participate.

RESULTS: Over the 21-week trial, at-home weekly screening testing participation rates were not inferior to onsite testing. Similarly, adherence to the weekly testing schedule was not inferior in the at-home arm. Participants in the at-home testing arm were able to test more consistently during and before returning from school breaks than those in the onsite arm.

CONCLUSIONS: Results support the noninferiority of at-home testing versus onsite testing both in terms of participation in testing and adherence to weekly testing. Implementation of at-home COVID-19 screening testing should be part of schools’ routine COVID-19 prevention efforts nationwide; however, adequate support is essential to ensure participation and persistence in regular at-home testing.

Mathematical pharmacodynamic modeling for antimicrobial assessment of ceftazidime/colistin versus gentamicin/meropenem combinations against carbapenem-resistant Pseudomonas aeruginosa biofilm

Ann Clin Microbiol Antimicrob. 2023 Jul 2;22(1):53. doi: 10.1186/s12941-023-00597-9.

ABSTRACT

BACKGROUND: Carbapenem-resistant Pseudomonas aeruginosa (CRPA) represents an escalating healthcare hazard with high mortality worldwide, especially in presence of biofilm. The current study aimed to evaluate the anti-biofilm potentials of ceftazidime, colistin, gentamicin, and meropenem alone and in combinations against biofilm-forming CRPA.

METHODS: Biofilm killing and checkerboard assay were performed to detect the effectiveness of combined antibiotics against biofilms and planktonic cells, respectively. The bacterial bioburden retrieved from the established biofilms following treatment with combined antibiotics was utilized to construct a three-dimensional response surface plot. A sigmoidal maximum effect model was applied to determine the pharmacodynamic parameters (maximal effect, median effective concentration, and Hill factor) of each antibiotic to create a mathematical three-dimensional response surface plot.

RESULTS: Data revealed statistically significant (p < 0.05) superior anti-biofilm potential in the case of colistin followed by a lower effect in the case of gentamicin and meropenem, while ceftazidime exhibited the least anti-biofilm activity. The fractional inhibitory concentration index (FICI ≤ 0.5) indicated synergism following treatment with the combined antibiotics. An elevated anti-biofilm activity was recorded in the case of gentamicin/meropenem compared to ceftazidime/colistin. Synergistic anti-biofilm potentials were also detected via the simulated pharmacodynamic modeling, with higher anti-biofilm activity in the case of the in vitro observation compared to the simulated anti-biofilm profile.

CONCLUSIONS: The present study highlighted the synergistic potentials of the tested antibiotic combinations against P. aeruginosa biofilms and the importance of the mathematical pharmacodynamic modeling in investigating the efficacy of antibiotics in combination as an effective strategy for successful antibiotic therapy to tackle the extensively growing resistance to the currently available antibiotics.

A study to evaluate association of nuclear grooving in benign thyroid lesions with RET/PTC1 and RET/PTC3 gene translocation

Thyroid Res. 2023 Jul 3;16(1):21. doi: 10.1186/s13044-023-00161-9.

ABSTRACT

INTRODUCTION: Papillary thyroid carcinoma (PTC) is the most common malignant lesion of the thyroid characterized by unique histological features like nuclear grooving, nuclear clearing, and intra-nuclear inclusions. However, nuclear grooves are observed even in benign thyroid lesions (BTL) like nodular goiter (NG), Hashimoto’s thyroiditis (HT), and follicular adenoma (FA) resulting in diagnostic dilemma of the presence of PTC in such BTL. RET/PTC gene translocation is one of the most common oncogenic rearrangements seen in PTC, known to be associated with nuclear grooving. Among different types of RET/PTC translocations, RET/PTC1 and RET/PTC3 gene translocations are the most common types. These translocations have also been identified in many BTL like hyperplastic nodules and HT. Our study aimed to determine the frequency of nuclear grooving in BTL and evaluate their association with RET/PTC1 and RET/PTC3 gene translocation.

METHODS: Formalin-fixed, paraffin-embedded (FFPE) tissue blocks of NG, HT, and FA were included in the study. The hematoxylin and eosin (H&E) stained sections were evaluated for the presence of nuclear grooving/high power field (hpf) and a scoring of 0 to 3 was used for the number of grooves. Sections of 10 μ thickness were cut and the cells containing the nuclear grooves were picked using Laser-Capture microdissection. About 20 to 50 such cells were microdissected in each of the cases followed by RNA extraction, cDNA conversion, realtime-polymerase chain reaction (RQ-PCR) for RET/PTC1 and RET/PTC3 gene translocation, and the findings were analyzed for statistical significance.

RESULTS: Out of 87 BTL included in the study, 67 (77.0%) were NG, 12 (13.7%) were HT, and 8 (9.2%) were FA. Thirty-two cases (36.8%) had nuclear grooving with 18 out of 67 NG, 6 out of 12 HT, and all 8 cases of FA showing a varying number of nuclear grooves. A significant association between the number of nuclear grooves with RET/PTC gene translocation (p-value of 0.001) was obtained. A significant association of HT with RET/PTC gene translocation (p-value of 0.038) was observed. RET/PTC1 and RET/PTC3 translocation were seen in 5 out of 87 cases, with HT showing positivity in 2 and FA in 1 case for RET/PTC1 and HT in 1 and FA in 2 cases for RET/PTC3 gene translocation with 1 case of FA being positive for both RET/PTC1 and RET/PTC3 gene translocation.

CONCLUSIONS: The frequency of nuclear grooving among BTLs in our study was 36.8%. Our study shows, that when BTLs, show nuclear grooves, with an increase in the nuclear size, oval and elongated shape, favors the possibility of an underlying genetic aberration like RET/PTC gene translocation, which in turn supports the reporting pathologist to suggest a close follow up of the patients on seeing such nuclear features on cytology or histopathology sample, particularly in HT.

Enterovirus meningitis without pleocytosis is not only a problem in children ; A retrospective observational study in adults

Jpn J Infect Dis. 2023 Jun 30. doi: 10.7883/yoken.JJID.2023.123. Online ahead of print.

ABSTRACT

Reverse-transcriptase polymerase chain reaction (RT-PCR)-confirmed Enterovirus (EV) meningitis without pleocytosis has reported in only children. We examined the frequency of EV meningitis without pleocytosis and compared clinical features in adults. We retrospectively analyzed the data of adult patients with EV meningitis confirmed by cerebrospinal fluid (CSF) RT-PCR. Among 17 patients finally included, 58.8% showed no pleocytosis. The median age and clinical symptoms were not different between the pleocytosis and the non-pleocytosis group. There were no statistically significant differences in terms of seasonal variation or time from the onset of meningitis symptoms to undergoing lumbar puncture. The peripheral white blood cell (WBC) count of the pleocytosis was significantly higher than in patients without pleocytosis. The median CSF pressure showed higher trend in the non-pleocytosis group. Patients with higher CSF pressure than the normal level were more common in the non-pleocytosis group. The median CSF protein values were higher than the normal values in both groups. We confirmed a high frequency of EV meningitis without pleocytosis in adults. An accurate diagnosis using RT-PCR is necessary when meningitis symptoms are prominent during an EV epidemic and CSF protein levels and pressure are high, even if the CSF WBC count is normal.
