The effect of phosphatidylserine administration on memory and symptoms of attention‐deficit hyperactivity disorder: a randomised,double‐blind,placebo‐controlled clinical trial

Background

Attention‐deficit hyperactivity disorder (ADHD) is the most commonly diagnosed behavioural disorder of childhood, affecting 3–5% of school‐age children. The present study investigated whether the supplementation of soy‐derived phosphatidylserine (PS), a naturally occurring phospholipid, improves ADHD symptoms in children.

Methods

Thirty six children, aged 4–14 years, who had not previously received any drug treatment related to ADHD, received placebo (n = 17) or 200 mg day^–1 PS (n = 19) for 2 months in a randomised, double‐blind manner. Main outcome measures included: (i) ADHD symptoms based on DSM‐IV‐TR; (ii) short‐term auditory memory and working memory using the Digit Span Test of the Wechsler Intelligence Scale for Children; and (iii) mental performance to visual stimuli (GO/NO GO task).

Results

PS supplementation resulted in significant improvements in: (i) ADHD (P < 0.01), AD (P < 0.01) and HD (P < 0.01); (ii) short‐term auditory memory (P < 0.05); and (iii) inattention (differentiation and reverse differentiation, P < 0.05) and inattention and impulsivity (P < 0.05). No significant differences were observed in other measurements and in the placebo group. PS was well‐tolerated and showed no adverse effects.

Conclusions

PS significantly improved ADHD symptoms and short‐term auditory memory in children. PS supplementation might be a safe and natural nutritional strategy for improving mental performance in young children suffering from ADHD.     

The geography of Medicare's hospital value-based purchasing in relation to market demographics

Objective

To illustrate the association between the sociodemographic characteristics of hospital markets and the geographic patterns of Medicare hospital value-based purchasing (HVBP) scores.

Data Sources and Study Setting

This is a secondary analysis of United States hospitals with a HVBP Total Performance Score (TPS) for 2019 in the Centers for Medicare and Medicaid Services (CMS) Hospital Compare database (4/2021 release) and American Community Survey (ACS) data for 2015–2019.

Study Design

This is a cross-sectional study using spatial multivariable autoregressive models with HVBP TPS and component domain scores as dependent variables and hospital market demographics as the independent variables.

Data Collection/Extraction Methods

We calculated hospital market demographics using ZIP code level data from the ACS, weighted the 2019 CMS inpatient Hospital Service Area file.

Principal Findings

Spatial autoregressive models using eight nearest neighbors with diversity index, race and ethnicity distribution, families in poverty, unemployment, and lack of health insurance among residents ages 19–64 years provided the best model fit. Diversity index had the highest statistically significant contribution to lower TPS (ß = −12.79, p < 0.0001), followed by the percent of the population coded to “non-Hispanic, some other race” (ß = −2.59, p < 0.0023), and the percent of families in poverty (ß = −0.26, p < 0.0001). Percent of the population was non-Hispanic American Indian/Alaskan Native (ß = 0.35, p < 0.0001) and percent non-Hispanic Asian (ß = 0.12, p < 0.02071) were associated with higher TPS. Lower predicted TPS was observed in large urban cities throughout the US as well as in states throughout the Southeastern US. Similar geographic patterns were observed for the predicted Patient Safety, Person and Community Engagement, and Efficiency and Cost Reduction domain scores but are not for predicted Clinical Outcomes scores.

Conclusions

The lower predicted scores seen in cities and in the Southeastern region potentially reflect an inherent—that is, structural—association between market sociodemographics and HVBP scores.     

How “age-friendly” are deprescribing interventions? A scoping review of deprescribing trials

Objective

To assess how age-friendly deprescribing trials are regarding intervention design and outcome assessment. Reduced use of potentially inappropriate medications (PIMs) can be addressed by deprescribing—a systematic process of discontinuing and/or reducing the use of PIMs. The 4Ms—“Medication”, “Mentation”, “Mobility”, and “What Matters Most” to the person—can be used to guide assessment of age-friendliness of deprescribing trials.

Data Source

Published literature.

Study Design

Scoping review.

Data Extraction Methods

The literature was identified using keywords related to deprescribing and polypharmacy in PubMed, EMBASE, Web of Science, ProQuest, CINAHL, and Cochrane and snowballing. Study characteristics were extracted and evaluated for consideration of 4Ms.

Principal Findings

Thirty-seven of the 564 trials identified met the review eligibility criteria. Intervention design: “Medication” was considered in the intervention design of all trials; “Mentation” was considered in eight trials; “Mobility” (n = 2) and “What Matters Most” (n = 6) were less often considered in the design of intervention. Most trials targeted providers without specifying how matters important to older adults and their families were aligned with deprescribing decisions. Outcome assessment: “Medication” was the most commonly assessed outcome (n = 33), followed by “Mobility” (n = 13) and “Mentation” (n = 10) outcomes, with no study examining “What Matters Most” outcomes.

Conclusions

“Mentation” and “Mobility”, and “What Matters Most” have been considered to varying degrees in deprescribing trials, limiting the potential of deprescribing evidence to contribute to improved clinical practice in building an age-friendly health care system.     

The impact of social deprivation on the response to a randomised controlled trial of a weight management intervention (BeWEL) for people at increased risk of colorectal cancer

Background

Although 45% of colorectal cancer (CRC) cases may be avoidable through appropriate lifestyle and weight management, health promotion interventions run the risk of widening health inequalities. The BeWEL randomised controlled trial assessed the impact of a diet and activity programme in overweight adults who were diagnosed with a colorectal adenoma, demonstrating a significantly greater weight loss at 12 months in intervention participants than in controls. The present study aimed to compare BeWEL intervention outcomes by participant deprivation status.

Methods

The intervention group of the BeWEL trial (n = 163) was classified by the Scottish Index of Multiple Deprivation (SIMD) quintiles into ‘more deprived’ (SIMD 1–2, n = 58) and ‘less deprived’ (SIMD 3–5, n = 105). Socio‐economic and lifestyle variables were compared at baseline to identify potential challenges to intervention adherence in the more deprived. Between group differences at 12 months in primary outcome (change in body weight) and secondary outcomes (cardiovascular risk factors, diet, physical activity, knowledge of CRC risk and psychosocial variables) were assessed by deprivation status.

Results

At baseline, education (P = 0.001), income (P < 0.001), spending on physical activity (P = 0.003) and success at previous weight loss attempts (P = 0.007) were significantly lower in the most deprived. At 12 months, no between group differences by deprivation status were detected for changes in primary and main secondary outcomes.

Conclusions

Despite potential barriers faced by the more deprived participants, primary and most secondary outcomes were comparable between groups, indicating that this intervention is unlikely to worsen health inequalities and is equally effective across socio‐economic groups.     

The use of haematopoietic stem cell transplantation in Fanconi anaemia patients: a survey of decision making among families in the US and Canada

Background

Fanconi anaemia (FA) is a rare genetic disorder associated with bone marrow failure (BMF), congenital anomalies and cancer susceptibility. Stem cell transplantation (SCT) offers a potential cure for BMF or leukaemia, but incurs substantial risks. Little is known about factors influencing SCT decision making.

Objective

The study objective was to explore factors influencing patients' with FA and family members' decision making about SCT.

Design

Using a mixed‐methods exploratory design, we surveyed US and Canadian patients with FA and family members who were offered SCT.

Main variables studied

Closed‐ended survey items measured respondents' beliefs about the necessity, risks and concerns regarding SCT; multivariable logistic regression was used to examine the association between these factors and the decision to undergo SCT. Open‐ended survey items measured respondents' perceptions of factors important to the SCT decision; qualitative analysis was used to identify emergent themes.

Results

The decision to undergo SCT was significantly associated with greater perceived necessity (OR = 2.81, P = 0.004) and lower concern about harms of SCT (OR = 0.31, P = 0.03). Qualitative analysis revealed a perceived lack of choice among respondents regarding the use of SCT, which was related to physician influence and respondent concerns about patients' quality of life.

Conclusions

Overall, study results emphasize the importance of the delicate interplay between provider recommendation of a medical procedure and patient/parental perceptions and decision making. Findings can help providers understand the need to acknowledge family members' perceptions of SCT decision making and offer a comprehensive discussion of the necessity, risks, benefits and potential outcomes.     

Effects of an electronic health record-based mobility assessment and automated referral for inpatient physical therapy on patient outcomes: A quasi-experimental study

Objective

To assess the effectiveness of a hospital physical therapy (PT) referral triggered by scores on a mobility assessment embedded in the electronic health record (EHR) and completed by nursing staff on hospital admission.

Data Sources

EHR and billing data from 12 acute care hospitals in a western Pennsylvania health system (January 2017–February 2018) and 11 acute care hospitals in a northeastern Ohio health system (August 2019–July 2021).

Study Design

We utilized a regression discontinuity design to compare patients admitted to PA hospitals with stroke who reached the mobility score threshold for an EHR-PT referral (treatment) to those who did not (control). Outcomes were hospital length of stay (LOS) and 30-day readmission or mortality. Control variables included demographics, insurance, income, and comorbidities. Hospital systems with EHR-PT referrals were also compared to those without (OH hospitals as alternative control). Subgroup analyses based on age were also conducted.

Data Extraction

We identified adult patients with a primary or secondary diagnosis of stroke and mobility assessments completed by nursing (n = 4859 in PA hospitals, n = 1749 in OH hospitals) who completed their inpatient stay.

Principal Findings

In the PA hospitals, patients with EHR-PT referrals had an 11.4 percentage-point decrease in their 30-day readmission or mortality rates (95% CI −0.57, −0.01) relative to the control. This effect was not observed in the OH hospitals for 30-day readmission (β = 0.01; 95% CI −0.25, 0.26). Adults over 60 years old with EHR-PT referrals in PA had a 26.2 percentage-point (95% CI −0.88, −0.19) decreased risk of readmission or mortality compared to those without. Unclear relationships exist between EHR-PT referrals and hospital LOS in PA.

Conclusions

Health systems should consider methodologies to facilitate early acute care hospital PT referrals informed by mobility assessments.     

No difference in self‐reported frequency of choking between infants introduced to solid foods using a baby‐led weaning or traditional spoon‐feeding approach

Background

Baby‐led weaning (BLW) where infants self‐feed family foods during the period that they are introduced to solid foods is growing in popularity. The method may promote healthier eating patterns, although concerns have been raised regarding its safety. The present study therefore explored choking frequency amongst babies who were being introduced to solid foods using a baby‐led or traditional spoon‐fed approach.

Methods

In total, 1151 mothers with an infant aged 4–12 months reported how they introduced solid foods to their infant (following a strict BLW, loose BLW or traditional weaning style) and frequency of spoon‐feeding and puree use (percentage of mealtimes). Mothers recalled if their infant had ever choked and, if so, how many times and on what type of food (smooth puree, lumpy puree, finger food and specific food examples).

Results

In total, 13.6% of infants (n = 155) had ever choked. No significant association was found between weaning style and ever choking, or the frequency of spoon or puree use and ever choking. For infants who had ever choked, infants following a traditional weaning approach experience significantly more choking episodes for finger foods (F_2,147 = 4.417, P = 0.014) and lumpy purees (F_2,131 = 6.46, P = 0.002) than infants following a strict or loose baby‐led approach.

Conclusions

Baby‐led weaning was not associated with increased risk of choking and the highest frequency of choking on finger foods occurred in those who were given finger foods the least often. However, the limitations of noncausal results, a self‐selecting sample and reliability of recall must be emphasised.

An investigation into the nutritional composition and cost of gluten‐free versus regular food products in the UK

Background

The gluten‐free (GF) food market has expanded considerably, although there is limited comparative evidence for the nutritional quality and cost of GF food products. The present study aims to compare the nutrient composition and cost of GF and gluten‐containing (regular) foods across 10 food categories in the UK.

Methods

Nutritional information and the cost of GF foods available in the UK (n = 679) and comparable regular foods (n = 1045) were systematically collected from manufacturer and supermarket websites. Foods were classified using UK front‐of‐pack labelling for content of fat, saturated fat, sugar and salt and nutrient content, and cost per 100 g were identified and compared between GF and regular foods.

Results

Overall, more GF foods were classified as containing high and medium fat, saturated fat, sugar and salt than regular foods, although this was not universally consistent. More GF bread and flour products contained high fat and sugar, whereas fewer GF crackers contained high fat and sugar compared to regular foods. High salt content was found more frequently in GF than regular products. On average, GF products were 159% more expensive than regular (£0.44/100 g versus £1.14/100 g). GF items were also more likely to be lower in fibre and protein content than regular foods.

Conclusions

Differences exist in the nutritional composition of GF and regular food. GF food is unlikely to offer healthier alternatives to regular foods, except for those who require a GF diet for medically diagnosed conditions, and it is associated with higher costs.     

Frontline work and racial disparities in social and economic pandemic stressors during the first COVID-19 surge

Objective

To assess the magnitude of racial–ethnic disparities in pandemic-related social stressors and examine frontline work's moderating relationship on these stressors.

Data Sources

Employed Californians' responses to the Institute for Governmental Studies (IGS) poll from April 16–20, 2020, were analyzed. The Pandemic Stressor Scale (PSS) assessed the extent to which respondents experienced or anticipated problems resulting from the inability to pay for basic necessities, job instability, lacking paid sick leave, unavailability of childcare, and reduced wages or work hours due to COVID-19.

Study Design

Mixed-effects generalized linear models estimated (1) racial–ethnic disparities in pandemic stressors among workers during the first COVID-19 surge, adjusting for covariates, and (2) tested the interaction between race–ethnicity and frontline worker status, which includes a subset of essential workers who must perform their job on-site, to assess differential associations of frontline work by race–ethnicity.

Data Collection

The IGS poll data from employed workers (n = 4795) were linked to the 2018 Centers for Disease Control and Prevention Social Vulnerability Index at the zip code level (N = 1068).

Principal Findings

The average PSS score was 37.34 (SD = 30.49). Whites had the lowest PSS score (29.88, SD = 26.52), and Latinxs had the highest (50.74, SD = 32.61). In adjusted analyses, Black frontline workers reported more pandemic-related stressors than White frontline workers (PSS = 47.73 vs. 36.96, p < 0.001). Latinxs reported more pandemic stressors irrespective of frontline worker status. However, the 5.09-point difference between Latinx frontline and non-frontline workers was not statistically different from the 4.6-point disparity between White frontline and non-frontline workers.

Conclusion

Latinx workers and Black frontline workers disproportionately reported pandemic-related stressors. To reduce stress on frontline workers during crises, worker protections like paid sick leave, universal access to childcare, and improved job security are needed, particularly for those disproportionately affected by structural inequities, such as racially minoritized populations.     

Time to delivery: Transfers for threatened preterm labour and prelabour rupture of membranes in Western Australia

Objective

To describe the outcomes of patients transferred to King Edward Memorial Hospital (KEMH) with signs of labour at preterm gestations.

Design

A retrospective observational study of the 69 cases transferred to KEMH during 2015.

Setting

Patient transfers from all locations across Western Australia (WA) to the sole tertiary perinatal centre in Perth.

Participants

Pregnant women within WA with threatened or actual preterm labour (PTL) or preterm prelabour rupture of membranes (PPROM) between 23 and 32 weeks gestation.

Main outcome measures

The occurrence of delivery during the admission and time‐to‐delivery as well as length of admission and association between clinical factors and time‐to‐delivery.

Results

The percentage of the study population delivered during the admission following transfer was 72.5%. Eighty‐six per cent of those who delivered did so within 72 hours of transfer. The median time from transfer to delivery was 1 day. Sixty‐three per cent of those who did not deliver during the admission progressed to 36 weeks gestation. Patients transferred with PPROM were less likely to deliver during the admission compared to those with uterine activity (50% versus 19.6%, P = 0.007) and nulliparas were more likely to deliver (93.5% versus 55.3%, P < 0.001).

Conclusion

The majority of women transferred with signs of PTL progress to delivery during the same admission with the highest risk of delivery being the first 72 hours following transfer. If the pregnancy is ongoing at 72 hours, there is a reasonable chance of progression to late preterm gestation supporting the return of woman to their place of origin for antenatal care following discharge.     

Participation of children on the autism spectrum in home,school, and community

Background

Children on the autism spectrum participate less frequently, and in a narrower range of activities, than their nonautistic peers, but little is known about exact participation patterns across contexts or how this is perceived by caregivers. This study aimed to document patterns of participation and caregiver views with regard to frequency and intensity of activities.

Method

Caregivers of children on the spectrum aged 5 (n = 90) and 9–10 years (n = 128) completed the Participation and Environment Measure for Children and Youth for home, school, and community. Caregivers reported on frequency of child's participation, level of involvement, and caregivers' desire for change in participation patterns.

Results

Item‐level analyses revealed similar patterns of participation across home, school, and community for both cohorts with some small age‐appropriate differences. Caregivers generally desired increased diversity, frequency, and involvement in activities but a decreased use of electronics (computers, games, TV, and DVDs).

Conclusion

The possibility of autism‐specific participation patterns could inform future interventions aimed at enhancing social inclusion. This warrants further investigation through multiinformant designs that seek the perspectives of the child and caregivers.

Mild–moderate congenital hearing loss: secular trends in outcomes across four systems of detection

Background

Universal newborn hearing screening (UNHS) targets moderate or greater hearing loss. However, UNHS also frequently detects children with mild loss that results in many receiving early treatment. The benefits of this approach are not yet established. We aimed to (i) compare language and psychosocial outcomes between four hearing loss detection systems for children aged 5–8 years with congenital mild–moderate hearing loss; (ii) determine whether age of detection predicts outcomes; and (iii) compare outcomes between children identified via well‐established UNHS and the general population.

Methods

Linear regression adjusted for potential confounding factors was used throughout. Via a quasi‐experimental design, language and psychosocial outcomes were compared across four population‐based Australian systems of hearing loss detection: opportunistic detection, born 1991–1993, n = 50; universal risk factor referral, born 2003–2005, n = 34; newly established UNHS, born 2003–2005, n = 41; and well‐established UNHS, born 2007–2010, n = 21. In pooled analyses, we examined whether age of detection predicted outcomes. Outcomes were similarly compared between the current well‐established UNHS system and typically developing children in the Early Language in Victoria Study, born 2003, n = 1217.

Results

Age at diagnosis and hearing aid fitting fell steadily across the four systems. For moderate losses, mean expressive language (P for trend .05) and receptive vocabulary (P for trend .06) improved across the four systems, but benefit was not obvious for mild losses. In pooled analyses, diagnosis before age six months predicted better language outcomes for moderate losses. Children with mild–moderate losses exposed to well‐established UNHS continue to experience expressive language scores well below children in the general population (adjusted mean difference ?8.9 points, 95% CI ?14.7 to ?3.1).

Conclusions

Treatment arising from UNHS appears to be clearly benefitting children with moderate hearing losses. However, rigorous trials are needed to quantify benefits, versus costs and potential harms, of early aiding of children with mild losses.     

Trichloroethylene exposure and somatic mutations of the VHL gene in patients with Renal Cell Carcinoma

Sex-associated effect of CETP and LPL polymorphisms on postprandial lipids in familial hypercholesterolaemia

Background  

This study assessed the gender-specific influence of the cholesteryl ester transfer protein (TaqIB, I405V) and lipoprotein lipase (S447X) polymorphisms on the response to an oral fat tolerance test in heterozygotes for familial hypercholesterolaemia.
