Authors: Chansky Melanie C. , Price Simani M. , Aikin Kathryn J. , O’Donoghue Amie C. 
Published: April 2022

Abstract
Background
Prescribing approved products for unapproved uses (off-label use) is not uncommon among physicians in certain medical specialties. Available evidence about an off-label use – both supportive and unsupportive – can influence prescribers’ decisions about a drug’s appropriateness for a particular case. The objectives of this study were: (1) to examine physician perceptions about off-label uses generally, including their awareness of unsupportive data; and (2) to explore the influence of disclosure information about unsupportive data on off-label prescribing decisions.

Methods
Semi-structured interviews were conducted between December 2019 and January 2020 with oncologists (n = 35) and primary care physicians (n = 35). Interviews explored general prescribing practices, understanding of and information sources for learning about off-label use of prescription drugs, awareness of unsupportive data related to off-label uses, and preferences and reactions to disclosure statements about the existence of unsupportive data related to an off-label use.

Results
Most participants reported prescribing drugs for off-label uses (with half reporting regular off-label prescribing). However, among those who prescribe off-label, approximately two-thirds had never seen unsupportive data about off-label uses. Physicians preferred a disclosure statement that provided a summary of the unsupportive data about the off-label use; this statement also led most physicians to say they were unlikely or less likely to prescribe the drug for that use.

Conclusions
This study suggests that physicians’ decision-making about prescribing for off-label uses of approved drugs may be influenced by awareness of unsupportive data. Our interviews also suggest that providing more information about unsupportive study findings may result in a reduction in reported prescribing likelihood.

Abstract
Introduction
Telemedicine use in nursing homes (NHs) expanded during the COVID-19 pandemic. The objectives of this study were to characterize plans to continue telemedicine among newly adopting NHs and identify factors limiting its use after COVID-19.

Methods
Key informants from 9 Wisconsin NHs that adopted telemedicine during COVID-19 were recruited. Semi-structured interviews and surveys were employed to identify participant perceptions about the value of telemedicine, implementation challenges encountered, and plans and barriers to sustaining its delivery after COVID-19. Directed content analysis and a deductive thematic approach using the Systems Engineering Initiative for Patient Safety (SEIPS) model was used during analyses. Quantitative and qualitative data were integrated to identify participant views on the value of telemedicine and the tools and work system enhancements needed to make telemedicine easier and more effective.

Results
All participating NHs indicated a preference to continue telemedicine after COVID-19. Urgent assessments of resident change-in-condition and cognitively based sub-specialty consultations were identified as the encounter types most amenable to telemedicine. Reductions in resident off-site encounters and minimization of resident therapy interruptions were identified as major benefits of telemedicine. Twelve work system enhancements needed to better sustain telemedicine were identified, including improvements to: 1) equipment/IT infrastructure; 2) scheduling; 3) information exchange; and 4) telemedicine facilitators.

Discussion
NHs that adopted telemedicine during COVID-19 wish to continue its use. However, interventions that enhance the integration of telemedicine into NH and off-site clinic work systems require changes to existing regulations and reimbursement models to sustain its utilization after COVID-19.
The role of depression and physical activity in the association of between sleep quality, and duration with and health-related quality of life among the elderly: a UK Biobank cross-sectional study

Published: April 2022

Abstract
Background
Although studies have shown that sleep quality (duration) is associated with health-related quality of life (HRQoL), most of these studies have been small-sized and targeted at young and middle-aged adults. In addition, few studies have explored the path mechanism of sleep disorders leading to impaired HRQoL.

Objectives
This study aimed to determine the association between sleep quality and duration and HRQoL among the elderly in the United Kingdom, assess whether depression mediated the association, and explore the role of physical activity (PA) in the path association.

Methods
Data were extracted from the baseline survey of the UK Biobank, a large prospective cohort study enrolling more than 500,000 participants, of which 52,551 older adults (aged ≥60 years) were included in the study. HRQoL was assessed using the European Quality of Life-5 Dimensions. Tobit and multivariate logistic regression models were used to determine the association between sleep quality and duration and HRQoL. The mediating and moderated mediation models were estimated using the PROCESS macro and MEDCURVE macro.

Results
The Tobit model showed that the elderly with short or long sleep duration (β = − 0.062, 95% confidence interval [CI] = − 0.071 to − 0.053; β = − 0.072, 95% CI = − 0.086 to − 0.058) had worse HRQoL after adjusting potential covariates. In the logistic regression models, we found an inverted U-shaped association between sleep duration and HRQoL. Moreover, a significant positive association was observed between sleep quality and HRQoL (all P < 0.05). The results also revealed that depression mediated the association between sleep disorders and HRQoL (sleep quality: β = 0.008, 95% CI = 0.007–0.010; sleep duration: θ = 0.001 [mean], 95% CI = 0.001–0.002). Furthermore, PA moderated all paths among sleep quality and duration, depression, and HRQoL, and greater effects were observed in the elderly with lower PA levels.

Conclusions
The findings show that poor sleep quality and duration were independently associated with worse HRQoL among the elderly in the United Kingdom. Furthermore, PA buffers the mediating effect of depression and adverse effects of sleep disorders on HRQoL. It is essential to properly increase PA and provide early intervention for depression in the elderly with sleep disorders to improve their HRQoL.

Abstract
Introduction
Periprosthetic joint infections (PJI) are a major complication in joint-arthroplasty. Rifampicin is often used as an additional agent to treat PJI, because it penetrates bacterial biofilms. However, rifaximin, belonging to the same antibiotic class as rifampicin, is frequently used to prevent episodes of hepatic encephalopathy in patients with cirrhosis and may induce resistance to rifampicin. The aim of this study was to examine the microbial pattern of periprosthetic joint infections in cirrhotic patients and to test the hypothesis that intake of rifaximin increases the rate of resistance to rifampicin in periprosthetic joint infections.

Methods
A cohort of cirrhotic patients and PJI (n = 25) was analysed on the characteristics of bacterial isolates from sonication and tissue analysis. In a second step a subgroup analysis on the development of rifampicin resistant bacterial specimens, depending on the intake of rifaximin (8 rifaximin intake patients vs. 13 non rifaximin intake patients) was performed.

Results
Intestinal bacteria were found in 50% of the specimens, which was significantly more frequent than in a control cohort. By comparison of the single bacterial isolates, rifampicin resistance was detected in 69.2% (9/13) of the rifaximin-intake samples. In contrast, the non-rifaximin-intake isolates only were resistant to rifampicin in 22.2% (4/18) of the cases (p = 0.01). The odds ratio for developing a rifampicin-resistance through rifaximin intake was calculated as OR = 13.5.

Conclusion
Periprosthetic joint infections have a high incidence of being caused by enteric bacteria in cirrhotic patients. Due to this change in microbial pattern and the innate resistance to rifampicin of most of gram-negative bacteria, the therapy with rifampicin should be carefully considered. The association between the use of rifaximin and developed resistance to rifampicin has a major impact on the treatment of PJI.

Published: April 2022

Abstract
Background
Gestational diabetes mellitus (GDM) is associated with adverse health consequences for women and their offspring. It is associated with maternal body mass index (BMI) and may be associated with gestational weight gain (GWG). But due to the heterogeneity of diagnosis and treatment and the potential effect of GDM treatment on GWG, the association between the two has not been thoroughly clarified. Compared to body weight, BMI has the advantage that it considers height during the whole course of pregnancy. Understanding BMI changes during pregnancy may provide new evidence for the prevention of GDM.

Methods
This study investigated the BMI change of pregnant women based on a retrospective study covering all communities in Tianjin, China. According to the results of GDM screening at 24–28 weeks of gestation, pregnancies were divided into the GDM group and the non-GDM group. We compared gestational BMI change and GWG in the two groups from early pregnancy to GDM screening. GWG was evaluated according to the IOM guidelines. Logistic regression was applied to determine the significance of variables with GDM.

Results
A total of 41,845 pregnant women were included in the final analysis (GDM group, n = 4257 vs. non-GDM group, n = 37,588). BMI gain has no significant differences between the GDM and non-GDM groups at any early pregnancy BMI categories (each of 2 kg/m2), as well as weight gain (P > 0.05). Early pregnancy BMI was a risk factor for GDM (OR 1.131, 95% CI 1.122–1.139). And BMI gain was associated with a decreased risk of GDM in unadjusted univariate analysis (OR 0.895, 95% CI 0.869–0.922). After adjusting on early pregnancy BMI and other confounding factors, the effect of BMI gain was no longer significant (AOR 1.029, 95% CI 0.999–1.061), as well as weight gain (AOR 1.006, 95% CI 0.995–1.018) and GWG categories (insufficient: AOR 1.016, 95% CI 0.911–1.133; excessive: AOR 1.044, 95% CI 0.957–1.138).

Conclusions
BMI in early pregnancy was a risk factor for GDM, while BMI gain before GDM screening was not associated with the risk of GDM. Therefore, the optimal BMI in early pregnancy is the key to preventing GDM.

Published: April 2022

Abstract
Objective
The aim of this study is to determine the frequency of neural tube defects (NTDs) and to examine the epidemiological characteristics of NTD related deaths in Turkey.

Methods
This nationwide descriptive study was included NTD related infant deaths, termination of pregnancy for fetal anomaly (ToPFA) and stillbirth cases registered in Death Notification System between 2014 and 2019, and patients diagnosed with NTD in the 2018 birth cohort.

Findings
In the 2018 birth cohort, there were 3475 cases of NTD at birth (27.5 per 10,000). The fatality rates for live-born babies with NTD in this cohort were 13.5% at first year, and 15.6% at the end of March, 2022. NTDs were associated with 11.7% of ToPFA cases, 2.5% of stillbirths and 2.8% of infant deaths in 2014–2019. NTD related stillbirth rate was 1.74 per 10,000 births, while NTD related ToPFA rate and infant mortality rate were 0.61 and 2.70 per 10,000 live births respectively. NTD-related stillbirth and infant mortality rate were highest in the Eastern region (3.64 per 10,000 births; 4.65 per 10,000 live births respectively), while ToPFA rate was highest in the North and West regions (1.17 and 0.79 per 10,000 live births respectively) (p < 0.05). Prematurity and low birth weight were the variables with the highest NTD related rates for stillbirths (11.26 and 16.80 per 10,000 birth), ToPFA (9.25 and 12.74) per 10,000 live birth), and infant deaths (13.91 and 20.11 per 10,000 live birth) (p < 0.05).

Conclusion
NTDs are common and have an important place among the mortality causes in Turkey. Primary prevention through mandatory folic acid fortification should be considered both to reduce the frequency of NTD and related mortality rates.
Matrix metalloproteinase 9 is associated with conjunctival microbiota culture positivity in Korean patients with chronic Stevens-Johnson syndrome
Authors: Moon Jayoon , Lee Yunjin , Yoon Chang Ho , Kim Mee Kum 
Published: April 2022

Abstract
Background
Stevens-Johnson syndrome (SJS) is an abnormal immune-response causing extensive exfoliation of the mucocutaneous tissue including conjunctiva. While several factors are associated with the alteration of conjunctival microbiota, the conjunctiva of SJS patients are found to harbor a different microbiota compared to healthy subjects. We investigated the conjunctival microbiota of Korean SJS patients, and identified factors associated with the conjunctival microbiota and its positive culture.

Methods
Medical records were retrospectively reviewed in 30 chronic SJS patients who had undergone conjunctival swab culture sampling. Demographic factors, chronic ocular surface complications score (COCS), tear break-up time (TBUT), tear secretion, tear matrix metalloproteinase 9 (MMP9), and results of conjunctival swab culture were assessed.

Results
Positive culture was seen in 58.1%. Gram positive bacteria was most commonly isolated, among which Coagulase-negative Staphylococci (45.5%) and Corynebacterium species (40.9%) were predominantly observed. Tear MMP9 positivity was observed significantly more in the positive culture group (100%) compared to the negative culture group (70%) (P = 0.041). Topical cyclosporine and corticosteroid were not associated with repetitive positive cultures. No significant differences in COCS, TBUT, and tear secretion were found between culture-positive and culture-negative groups.

Conclusion
Our study suggests that tear MMP9 positivity may be related with the presence of an abnormal ocular surface microbiota in chronic SJS patients.
Longitudinal association between the timing of adiposity peak and rebound and overweight at seven years of age
Authors: Lin Dan , Chen Di-di , Huang Jun , Li Yun , Wen Xiao-sa , Shi Hui-jing 
Published: April 2022

Abstract
Background
The timing of adiposity peak (AP) or adiposity rebound (AR) is a determinant of overweight or obesity in adolescence and adulthood. However, limited studies have reported the association in young school-age children. We aimed to evaluate this association and explore the role of health behaviours in it.

Methods
Routinely collected, sequential, anthropometric data from the 1st to 80th months of age were used to estimate AP and AR timings in 2330 children born in Shanghai between 2010 and 2013. Multivariate regression analyses were applied to identify the associations between the AP or AR timings and the risk of developing overweight or obesity in first-grade school children. The roles of health behaviours, including dietary patterns, physical activity level, sleep and snacking habits, and screen time, were also evaluated.

Results
Children with a late AP or an early AR were at higher risk of overweight but not obesity or central obesity in their first grade. A high physical activity level was associated with a lower risk of having overweight in children with a late AP, and limited screen time was associated with a decreased risk of having overweight or obesity in children with an early AR. The absence of a late-night snacking habit in children with a non-early AR indicated a decreased risk of having overweight. However, this association was not observed among children with an early AR.

Conclusion
The timings of AP and AR are tied to overweight in middle childhood. Prevention strategies are suggested to move forward to control late AP and early AR.

Authors: Sithole Prosperity A. , Motshabi-Chakane Palesa , Muteba Michel K. 
Published: April 2022

Abstract
Background
Orofacial clefts (OFCs) are the commonest congenital anomalies of the head and neck. Their aetiology is multifactorial, and prevalence has a geographical variation. This study sought to describe OFC cases that presented for surgery.

Objectives
The study aimed to describe the preoperative characteristics, concomitant congenital anomalies and perioperative outcomes of children presenting for cleft repair surgery over a 5-year period at Charlotte Maxeke Johannesburg Academic Hospital (CMJAH).

Methods
A retrospective descriptive record review for children under the age of 14 years who presented for cleft repair surgery at Charlotte Maxeke Johannesburg Academic Hospital (CMJAH) during a 5-year period, from 1 January 2014 to 31 December 2018. Descriptive and comparative statistics were used to report the results.

Results
A total of 175 records were included in the study. The median (IQR) age was 11 (6—27) months, with a predominance of males 98 (56%). Most of the children had cleft lip and palate (CLP) 71(41%). The prevalence of concomitant congenital anomalies was 22%, emanating mostly from head and neck congenital anomalies. Nine syndromes were identified in 15 children with syndromic clefts. Twenty-nine percent of children were underweight for age. There were 25 anaesthetic related complications, commonly airway related. Six children with complex multiple congenital anomalies were admitted in the intensive care unit postoperatively. No mortalities were recorded.

Conclusion
Majority of children with orofacial clefts underwent cleft repair surgery without serious complications and intensive care unit admission. Only six children were diagnosed with significant anomalies needing intensive care management.
Associations between alexithymia, parental rearing styles, and frequency of drug use in male methamphetamine dependence patients
Authors: Huang Cui , Yuan Qiuyu , Shi Shengya , Ge Menglin , Sheng Xuanlian , Yang Meng , Zhang Ling , Wang Lei , Zhang Kai , Zhou Xiaoqin 
Published: April 2022

Abstract
Background
Alexithymia, which is characterized by difficulty identifying and describing feelings, is a stable personality trait and it has been associated with early life experiences. Methamphetamine dependence patients with high level of alexithymia may be particularly vulnerable to engaging in more frequent methamphetamine use. Therefore, we aimed to evaluate whether alexithymia was associated with frequency of methamphetamine use. Additionally, the current study sought to examine early-life factors associated with the development of alexithymia, i.e., parental rearing styles.

Method
Participants were 108 non-injecting methamphetamine dependent patients from a male compulsory detoxification center. The level of alexithymia was assessed by Toronto Alexithymia Scale-20(TAS-20). In addition, we applied Egna Minneu av. Bardndosnauppforstran (EMBU) to assess the parental rearing styles, including the dimensions of warmth, rejection, punishment/strictness, overinvolvement, overprotection, and favoring.

Results
The total score of TAS-20 was positively correlated with frequency of methamphetamine use (r = 0.26, p < 0.01). Specifically, except for externally oriented thinking, difficulty identifying feelings (r = 0.23, p < 0.05) and difficulty describing feelings (r = 0.25, p < 0.05) were positively correlated with frequency of methamphetamine use. Multiple linear regression showed that more maternal rejection (B = 0.59, p = 0.002), or less maternal warmth (B = -0.22, p = 0.004) was associated with higher levels of alexithymia. Ordinal logistic regression showed that for every 1 score increase in the total score of TAS-20, there was a 1.06 times risk of a one level increase in the level of methamphetamine use frequency (OR = 1.06, p = 0.01).

Conclusions
These results have major implications for understanding the role of alexithymia in craving and addiction, while providing a further and explicit entry point for addiction treatment. Moreover, more attention should be focused on parenting in relation to early experiences.
Associations of youth mental health, parental psychological distress, and family relationships during the COVID-19 outbreak in China

Published: April 2022

Abstract
Background
The COVID-19 pandemic has brought significant changes in society and family life, which could be particularly difficult for parents. The present study examines the relationship between youth mental health and parental psychological distress after the first peak of the COVID-19 Outbreak in China. The parent-child and marital relationships were examined as moderators of the above relationship.

Methods
Parents and their children aged 10 to 18 years were recruited for this study. The parents completed the Depression Anxiety Stress Scales-21 (DASS-21), the Strengths and Difficulties Questionnaire (SDQ), and a subset of items from the questionnaire of the COVID-19 Supporting Parents, Adolescents, and Children in Epidemics (Co-SPACE) survey of parental mental health, child’s psychological symptoms, parent-child, and marital relationship. Several multiple linear regressions were used to analyze the data.

Results
The largest variance in parental mental health was explained by the child’s psychological symptoms (effect size beta = 0.27). Parent-child (effect size beta = -0.13) and marital relationship (effect size beta = -0.21) were negatively associated with parental mental health. The relationship between child’s psychological symptoms and parental mental health was moderated by marital relationship (effect size beta = -0.07). Both parent-child and marital relationships presented with a significant interaction with impact scores, while only parent-child relationships with burden scores.

Conclusions
Youth mental health problems were significantly associated with parental psychological symptoms during the early phase of the COVID-19 pandemic The parent-child and marital relationship moderated the association between youth psychological symptoms and parental mental health. Interventions for alleviating parenting stress and support services that improve family relationships may be particularly effective in reducing parental psychological distress associated with future COVID-19 or related crises.
