Call me maybe: Risk factors of impaired social contact during the COVID‐19 pandemic and associations with well‐being

alexandrossfakianakis shared this article with you from Inoreader

Abstract

The COVID-19 pandemic caused major societal changes worldwide, with the most notable being lockdowns and restrictions on social contact. We conducted a longitudinal study (total n = 1907) in Germany with two time points to (1) identify demographic risk factors of impaired social contact during the pandemic, as well as investigate potential consequences of (2) impaired social contact and (3) different modes of communication on individuals' well-being during the first lockdown in spring 2020. Results indicate that particularly individuals living alone and being unable to work reported a lower frequency of (face-to-face) contact in comparison with participants living with others or working. Impaired social contact was indirectly associated with a negative development in well-being (life satisfaction, anxiety and depression) over time, and this relation was mediated via relatedness. Moreover, the frequency of face-to-face and phone communication during lockdown was po sitively associated with relatedness and well-being; however, digital communication was not. The findings stress the importance of maintaining social contact in times of social distancing and of fostering reconnection between individuals once the pandemic is over.

Carglumic acid in methylmalonic acidemia: Use of breast milk as an alternative vehicle to water

We aim to report the use of breast milk (BM) as an alternative vehicle in a neonate with methylmalonic acidemia rejecting carglumic acid (NCG) diluted in water. The patient presented symptomatic acidemia and hyperammonemia and after refusal of oral NCG administration, the clinician consulted the Pharmacy Department for advice. Data sheet of NCG does not recommend administration in other vehicle than water. Consequently, a dissolution test was conducted in BM showing correct dissolution. The solution was well tolerated, and plasma ammonium concentrations remained within range in subsequent analytical controls.


Abstract

What Is Known and Objective

Carbaglu® or N-carbamylglutamate (NCG) is not recommended for administration in a vehicle other than water. We aim to report the use of breast milk (BM) as an alternative vehicle in a neonate rejecting NCG diluted in water.

Case Summary

A neonate diagnosed with methylmalonic acidemia presented symptomatology of acidemia and hyperammonemia. After the patient refused oral NCG administration, a dissolution test was conducted in BM showing correct dissolution. The NCG-BM solution was tolerated and plasma ammonium concentrations remained within range in subsequent analytical controls.

What Is New and Conclusion

BM as a vehicle for NCG is a safe and effective option for patients who refuse suspension in water and could lead to better treatment compliance in paediatric patients.

Adapting narrative exposure therapy with a tribal community: A community‐based approach

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Objective

American Indian (AI) individuals are at increased risk for present-day trauma exposure and associated negative outcomes, as well as ongoing effects of intergenerational trauma exposure and adversity. However, few empirically supported treatments exist that are specifically tailored and/or tested with AI communities. This study describes the process of selecting, adapting, and implementing narrative exposure therapy (NET) with an AI community.

Methods

A community and academic partnership was formed and worked together to make culturally mindful changes to NET to best fit the needs of the community. The partnership incorporated community leaders/Elders (n = 7), providers (n = 11), and participants seeking treatment (n = 50) to implement an iterative process of adapting and implementing the adapted form of NET.

Results

Key adaptions included addressing historical and intergenerational trauma, greater protections for confidentiality in a small community, and incorporation of cultural customs and traditions. Overall, the adapted form of NET was favorably received by the participants, and the implementation appeared to be feasible, with improved retention over past trials of adapted trauma-focused treatments with this community and with highly positive satisfaction ratings and feedback.

Conclusions

NET was shown to be an appropriate approach for this AI community and should be considered as a treatment option for other AI communities. Future work should consider strategies outlined in this adaption as well as following a similar process for working with AI communities to implement culturally appropriate interventions for trauma-related symptoms.

Molecular basis for avirulence of spontaneous variants of Porphyromonas gingivalis: genomic analysis of strains W50, BE1 and BR1

alexandrossfakianakis shared this article with you from Inoreader

Abstract

The periodontal pathogen Porphyromonas gingivalis is genetically heterogeneous. However, the spontaneous generation of phenotypically different sub-strains has also been reported. McKee (McKee et al., 1988) cultured P. gingivalis W50 in a chemostat during investigations into the growth and properties of this bacterium. Cell viability, on blood agar plates, revealed two types of non-pigmenting variants, W50 Beige (BE1) and W50 Brown (BR1) in samples grown in a high haemin medium after day 7 and the population of these variants increased to approximately 25% of the total counts by day 21. W50, BE1 and BR1 had phenotypic alterations in pigmentation, reduced protease activity and haemagglutination, and susceptibility to complement killing. Furthermore, the variants exhibited significant attenuation in a mouse model of virulence. Other investigators showed that in BE1, the predominant extracellular Arg-gingipain was RgpB, and no reaction with an A-LPS specific MAb 1B 5 (Collinson et al., 1998; Slaney et al., 2006). In order to determine the genetic basis for these phenotypic properties we performed hybrid DNA sequence long reads using Oxford Nanopore, and the short paired-end DNA sequence reads of Illumina Hiseq platforms to generate closed circular genomes of the parent and variants. Comparative analysis indicated loss of intact kgp in the 20 kb region of the hagA-kgp locus in the two variants BE1 and BR1. Deletions in hagA led to smaller open reading frames in the variants, and BR1 had incurred a major chromosomal DNA inversion. Additional minor changes to the genomes of both variants were also observed. Given the importance of Kgp and HagA to protease activity and haemagglutination respectively in this bacterium, genomic changes at this locus may account for most of the phenotypic alterations of the variants. The homologous and repetitive nature of hagA and kgp, and the features at the inverted jun ctions are indicative of specific and stable homologous recombination events which may underlie the genetic heterogeneity of this species.

A novel risk score for disease control prediction of Chronic rhinosinusitis

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Objectives

To assess the impact of risk factors on the disease control among CRS patients, following 1 year of functional endoscopic sinus surgery (FESS), and combining the risk factors to formulate a convenient, visualized prediction model.

Design

A retrospective and nonconcurrent cohort study

Setting and Participants

A total of 325 patients with Chronic rhinosinusitis (CRS) from June 2018 to July 2020 at A, B, C hospital.

Main Outcomes Measures

Outcomes were time to event measures: the disease control of CRS after surgery 1 year. The presence of nasal polyps, smoking habits, allergic rhinitis (AR), the ratio of tissue eosinophil (TER), and peripheral blood eosinophil count (PBEC)and asthma was assessed. The logistic regression models were used to conduct multivariate and univariate analyses. Asthma, TER, AR, PBEC were also included in the nomogram. The calibration curve and AUC (Area Under Curve) were used to evaluate the forecast performance of the model.

Results

In univariate analyses, most of the covariates had significant associations with the endpoints, except for age, gender, and smoking. The nomogram showed the highest accuracy with an AUC of 0.760 (95% CI, 0.688-0.830) in the training cohort.

Conclusions

In this cohort study that included the asthma, AR, TER, PBEC had significantly affected the disease control of CRS after surgery. The model provided relatively accurate prediction in the disease control of CRS after FESS and served as a visualized reference for daily diagnosis and treatment.

Subjective Sleep Complaints were Associated with Painful Temporomandibular Disorders in Adolescents: the Epidor‐Adolescere Study

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

Sleep disturbances in adolescents has received a lot of attention in the literature and it is recognized as a serious health concern. The association between pain and sleep disturbances in adolescents has been extensively studied. However, to the best of our knowledge, there is a lack of studies investigating the association between various subjective sleep variables and painful TMD in adolescents.

Objectives

to investigate the association between painful TMD and subjective sleep variables in adolescents' non-clinical sample. We conducted a cross-sectional study. TMD was classified according to the RDC/TMD criteria. The Revised Face Scale evaluated TMD pain intensity, and pressure pain thresholds (PPTs) were assessed in trigeminal and extra-trigeminal areas. The subjective sleep variables were assessed according to the Sleep Disturbance Scale for Children and Sleep Behavior Questionnaire.

Results

The final sample consisted of 690 adolescents (12.7±0.76 years), with 16.2% of them presenting painful TMD. Adolescents who frequently reported waking up more than twice per night and feeling tired when awake were more likely to present painful TMD symptoms [OR= 1.7 (95% CI: 1.04-2.90); p=0.034 and OR= 1.6 (95% CI: 1.01-2.48); p=0.046, respectively]. The intensity of TMD pain was negatively associated with sleep quality (p=0.015). Also, PPT values in the trigeminal and extra-trigeminal areas were negatively associated with total sleep time (p= 0.048 and p=0.042, respectively).

Conclusions

the present results point out the importance of considering sleep complaints associated with painful TMD in adolescents.

Plasma trough concentration distribution and safety of high‐dose teicoplanin for patients with augmented renal clearance

alexandrossfakianakis shared this article with you from Inoreader
Plasma trough concentration distribution and safety of high-dose teicoplanin for patients with augmented renal clearance

Teicoplanin plasma trough concentration (C min) and probability rates of C min > 10 mg/L in the augmented renal clearance (ARC) and non-ARC groups on the third day of medication (day 3) and during the dose maintenance period. After the HD, plasma samples were collected before the third day of medication. The teicoplanin C min values in the ARC and non-ARC groups were 17.3 ± 9.2 mg/L and 15.5 ± 7.9 mg/L, respectively (p = 0.663) (Figure A). The probability rate of C min > 10 mg/L also did not differ significantly between the two groups (85.7% [6/7] vs. 60.0% [6/10], p = 0.338, Figure C). During the dose maintenance period (3 days after medication), the teicoplanin C min was significantly lower in ARC group than in the non-ARC group (18.3 ± 5.1 mg/L vs. 25.5 ± 11.9 mg/L, p = 0.016, Figure A), while there was no significant difference in the probability rate of C min > 10 mg/L between the two groups (90.0% [9/10] vs. 96.2% [25/26], p = 0.484, Figure C). After the LD, plasma samples were collected before the third day of medication. The teicoplanin C min values in the ARC and non-ARC groups were 6.8 ± 3.9 mg/L and 7.9 ± 3.1 mg/L, respectively (p = 0.585) (Figure B). The probability rate of C min > 10 mg/L did not differ significantly between the two groups (20.0% [1/5] vs. 11.1% [1/9], p = 1.000, Figure D). During the dose maintenance period, the teicoplanin C min values in the ARC and non-ARC groups were 12.2 ± 6.3 mg/L and 13.0 ± 4.6 mg/L, respectively (p = 0.713) (Figure B). The probability rate of C min > 10 mg/L was 61.5% (8/13) in both groups (Figure D). It should be noted that on the third day of medication, the HD group had a significantly higher teicoplanin C min than the LD group for ARC (17.3 ± 9.2 mg/L vs. 6.8 ± 3.9 mg/L, p = 0.039, Figure A and B), but there was no significant intergroup difference in the probability rates of C min > 10 mg/L (85.7% [6/7] vs. 20.0% [1/5], p = 0.072, Figures C and D). During the dose maintenance period, the teicoplanin C min was significantly higher in the HD group than in the LD group for ARC (18.3 ± 5.1 mg/L vs. 12.2 ± 6.3 mg/L, p = 0.022, Figures A and B), while there was no significant intergroup difference in their probability rates of C min > 10 mg/L (90.0% [9/10] vs. 61.5% [8/13], p = 0.179, Figures C and D). Notes: A, HD; B, LD; C, HD; D, LD; *p < 0.05.


Abstract

What Is Known and Objective

There are few reports on the distribution of the plasma trough concentration (C min) of teicoplanin in patients with augmented renal clearance (ARC) and on the safety of a high-dose regimen (HD; 800 mg loading dose for q12h three times followed by an 800 mg qd maintenance dose). The objective of this study was to determine the C min values of teicoplanin in ARC patients using HD teicoplanin to provide a reference for individualized medication.

Methods

Data on patients treated with teicoplanin from January 2019 to January 2021 were collected retrospectively and divided into ARC (creatinine clearance rate [CCr] >130 ml/min, n = 22) and non-ARC (60 ml/min ≤ CCr ≤130 ml/min, n = 24) groups. The C min values in the two patient groups were analysed during the HD and the low-dose regimen (LD; all other regimens) on the third day of medication and during the dose maintenance period. Liver and kidney function indexes were also analysed before and after medication.

Results and Discussions

On the third day of the HD, C min did not differ significantly between the ARC and non-ARC groups (17.3 ± 9.2 mg/L [mean ± SD] vs. 15.5 ± 7.9 mg/L, p = 0.663), while C min in the ARC group was significantly lower for the LD (6.8 ± 3.9 mg/L, p = 0.039). During the dose maintenance period, C min in the ARC group when receiving the HD (18.3 ± 5.1 mg/L) was significantly lower than that in the non-ARC group (25.5 ± 11.9 mg/L, p = 0.016) and significantly higher than that for the LD (12.2 ± 6.3 mg/L, p = 0.022). Nephrotoxicity and hepatotoxicity incidence rates did not differ significantly between these groups.

What Is New and Conclusion

These results suggest that it is necessary to apply a loading dose of 800 mg (but not higher) q12h three times for patients with ARC, with 800 mg needed as a maintenance dose during severe infection, and 600 mg or 400 mg for mild infection.

Validation of the Augmented Renal Clearance in Trauma Intensive Care scoring system for augmented renal clearance prediction in a trauma subgroup of a mixed ICU population

alexandrossfakianakis shared this article with you from Inoreader
Validation of the Augmented Renal Clearance in Trauma Intensive Care scoring system for augmented renal clearance prediction in a trauma subgroup of a mixed ICU population

(Left) ROC curves for ARC detection in trauma subgroup: comparison between ARCTIC score ROC curve and regression ROC curve. AUC, area under the curve; CI, confidence interval. (Right) ROC curves for ARC detection in medical/surgical subgroup: comparison between ARCTIC score ROC curve and regression ROC curve.


Abstract

What is known and Objective

Augmented renal clearance is prevalent in trauma patients and leads to subtherapeutic levels of renally eliminated medications with potentially unfavourable clinical outcomes. The Augmented Renal Clearance of Trauma in Intensive Care (ARCTIC) score has been developed to predict augmented renal clearance in critically ill trauma patients. Our primary objective was to validate this score among the trauma subgroup of a mixed intensive care patient cohort.

Methods

This single-centre, retrospective, observational cohort study assessed augmented renal clearance using a timed 24-h urine collection performed weekly. ARC was defined as a measured creatinine clearance of ≥130 ml/min/1.73 m2. ARCTIC score performance was evaluated through a receiver operator characteristic curves and analysis of sensitivities and specificities for the trauma subgroup, the medical/surgical subgroup and the pooled cohort.

Results and Discussion

Augmented renal clearance was observed in 33.9% (n = 58) of trauma patients (n = 171) and 15.7% (n = 24) of medical/surgical patients (n = 153). Examination of different cutoffs for the ARCTIC score in our trauma population confirmed that the optimal cutoff score was ≥6. Comparison between ROC curves for ARCTIC score and for regression model based upon our data in trauma patients indicated validation of the score in this subgroup. Comparison of sensitivities and specificities for ARCTIC score between trauma (93.1% and 41.6%, respectively) and medical/surgical subjects (87.5% and 49.6%, respectively) showed no clinical nor statistical difference, suggesting validation for the medical/surgical subgroup as well.

What is new and Conclusion

In our mixed ICU population, the ARCTIC score was validated in the trauma subgroup. We also found that the score performed well in the medical/surgical population. Future studies should assess the performance of the ARCTIC score prospectively.
