RESUMEN
Access to healthcare is inequitable. Poverty, natural disasters and war disproportionally effect those most vulnerable, including children. Non-governmental organizations (NGO) hold a vital role in providing pediatric care in these contexts. Here we describe the delivery and challenges of Pediatric Anesthesia with two such non-governmental organizations; Médecins Sans Frontières (MSF) and Mercy Ships. Descriptions of both are followed by case studies.

Understanding the factors that mediate carbon (C) cycling is increasingly important as anthropogenic activities and climate change alter ecosystems. Decomposition rates mediate C cycling and are in part regulated by sodium (Na) where Na is limiting up to some threshold after which Na becomes stressful and reduces decomposition rates (i.e., the Sodium Subsidy-Stress hypothesis). An overlooked pathway by which decomposers encounter increased salts like NaCl is through plants, which often take up Na in proportion to soil concentrations. Here we tested the hypothesis that Na addition through litter (detritus) and water and their interaction would impact detrital processing and leachate chemistry. Laboratory riparian soil mesocosms received either artificial litter (100% cellulose sponges) soaked in 0.05% NaCl (NaClL) or just H2O (H2OL: control) and half of each litter treatment received weekly additions of 150 ml of either 0.05% NaCl water (NaClW) or just H2O (H2OW: control). After 8 weeks decomposition was higher in NaCl addition treatments (both NaClL and NaClW and their combo) than controls (H2OL + H2OW) but reflected a unimodal relationship where the saltiest treatment (NaClL + NaClW) was only marginally higher than controls indicating a subsidy-stress response. Previous studies in this system found that Na addition in either water or litter decreased decomposition. However, differences may reflect a phenology of Na demand where Na-limitation increases in the spring (this study). These results indicate that our understanding of how Na impacts detrital processes, C cycling, and aquatic-terrestrial linkages necessitates incorporation of temporal dynamics.

BACKGROUND: Schizophrenia (SZ) and bipolar I disorder (BD-I) are chronic mental health disorders often treated with antipsychotic medications. This qualitative study sought to better understand disease burden and treatment experiences with oral antipsychotic medications in participants living with SZ or BD-I. METHODS: Six 90-min focus groups were conducted with participants diagnosed with SZ or BD-I. Trained moderators facilitated discussions using a semistructured guide. Participants described symptoms, impacts of disease, and experiences with oral antipsychotic medications, whether favourable or unfavourable. RESULTS: Among participants with SZ (n = 15; 3 groups, 5 per group), 53% were male and 33% were white, with a mean of 18.6 years since diagnosis. Of participants with BD-I (n = 24; 3 groups, 8 per group), 33% were male and 42% were white, with a mean of 13.0 years since diagnosis. Participants described numerous symptoms of their illnesses that impacted relationships and daily life, including effects on emotional health, the ability to work, and encounters with law enforcement. Previous antipsychotic medications were deemed effective by 14/15 (93%) participants with SZ and 12/16 (75%) participants with BD-I. Most participants with SZ (13/15; 87%) or with BD-I (16/24; 67%) reported discontinuing their antipsychotic medication at some point. Side effects were a common reason for discontinuing or switching medications for participants with SZ (8/15; 53%) and for those with BD-I (11/24; 46%). The most common side effects reported in both cohorts were weight gain, drowsiness, sexual problems, and neurologic symptoms. Side effects negatively affected quality of life, leading to serious health problems and issues with self-esteem. CONCLUSIONS: People living with SZ or BD-I cited a range of favourable and unfavourable experiences with oral antipsychotic medications. Most participants reported that their antipsychotics were effective at controlling their symptoms, but multiple side effects impacted their quality of life, caused additional serious health problems, and often led to discontinuation of or switching antipsychotics. Findings from this study contribute to a better understanding of patients' experiences with antipsychotics and highlight a need for new medications with favourable benefit/risk profiles.

Alpha-1 antitrypsin deficiency (AATD) is characterized by neutrophil-dominated inflammation resulting in emphysema. The cholesterol-rich neutrophil outer plasma membrane plays a central role in adhesion and subsequent transmigration to underlying tissues. This study aimed to investigate mechanisms of increased neutrophil adhesion in AATD and whether alpha-1 antitrypsin (AAT) augmentation therapy abrogates this effect. Plasma and blood neutrophils were donated by healthy controls (n = 20), AATD (n = 30), and AATD patients after AAT augmentation therapy (n = 6). Neutrophil membrane protein expression was investigated using liquid chromatography-tandem mass spectrometry. The effect of once-weekly intravenous AAT augmentation therapy was assessed by calcium fluorometric, µ-calpain, and cell adhesion assays. Decreased neutrophil plasma membrane cholesterol content (P = 0.03), yet increased abundance of integrin α-M (fold change 1.91), integrin α-L (fold change 3.76), and cytoskeletal adaptor proteins including talin-1 (fold change 4.04) were detected on AATD neutrophil plasma membrane fractions. The described inflammatory induced structural changes were a result of a more than twofold increased cytosolic calcium concentration (P = 0.02), leading to significant calcium-dependent µ-calpain activity (3.5-fold change; P = 0.005), resulting in proteolysis of the membrane cholesterol trafficking protein caveolin-1. Treatment of AAT-deficient individuals with AAT augmentation therapy resulted in increased caveolin-1 and membrane cholesterol content (111.8 ± 15.5 vs. 64.18 ± 7.8 µg/2 × 107 cells before and after treatment, respectively; P = 0.02), with concurrent decreased neutrophil integrin expression and adhesion. Results demonstrate an auxiliary benefit of AAT augmentation therapy, evident by a decrease in circulating inflammation and controlled neutrophil adhesion.

OBJECTIVES: To evaluate the economic case for nationwide scale-up of the World Health Organization (WHO) Surgical Safety Checklist using cost-effectiveness and benefit-cost analyses. BACKGROUND: The Checklist improves surgical outcomes but the economic case for widespread use remains uncertain. For perioperative quality improvement interventions to compete successfully against other worthwhile health and nonhealth interventions for limited government resources they must demonstrate cost-effectiveness and positive societal benefit. METHODS: Using data from 3 countries, we estimated the benefits as the total years of life lost (YLL) due to postoperative mortality averted over a 3âyear period; converted the benefits to dollar equivalent values using estimates of the economic value of an additional year of life expectancy; estimated total implementation costs; and determined incremental cost-effectiveness ratio (ICER) and benefit-cost ratio (BCR). Costs are reported in international dollars using Word Bank purchasing power parity conversion factors at 2016 price-levels. RESULTS: In Benin, Cameroon, and Madagascar ICERs were: $31, $138, and $118 per additional YLL averted; and BCRs were 62, 29, and 9, respectively. Sensitivity analysis demonstrated that the associated mortality reduction and increased usage due to Checklist scale-up would need to deviate approximately 10-fold from published data to change our main interpretations. CONCLUSIONS: According to WHO criteria, Checklist scale-up is considered "very cost-effective" and for every $ 1 spent the potential return on investment is $9 to $62. These results compare favorably with other health and nonhealth interventions and support the economic argument for investing in Checklist scale-up as part of a national strategy for improving surgical outcomes.

OBJECTIVE: Surgical site infection (SSI) prevention remains significant, particularly in the era of antimicrobial resistance. Feedback on practices and outcomes is known to be key to reduce SSI rates and optimize antibiotic usage. However, the optimal method, format and frequency of feedback for surgical teams remains unclear. The objective of the study is to understand how data from surveillance and audit are fed back in routine surgical practice. METHODS: A systematic scoping review was conducted, using well-established implementation science frameworks to code the data. Two electronic health-oriented databases (MEDLINE, EMBASE) were searched to September 2019. We included studies that assessed the use of feedback as a strategy either in the prevention and management of SSI and/or in the use of antibiotics perioperatively. RESULTS: We identified 21 studies: 17 focused on SSI rates and outcomes and 10 studies described antimicrobial stewardship for SSI (with some overlap in focus). Several interventions were reported, mostly multimodal with feedback as a component. Feedback was often provided in written format (62%), either individualized (38%) or in group (48%). Only 25% of the studies reported that feedback cascaded down to the frontline perioperative staff. In 65% of the studies, 1 to 5 implementation strategies were used while only 5% of the studies reported to have utilized more than 15 implementation strategies. Among studies reporting antibiotic usage in surgery, most (71%) discussed compliance with surgical antibiotic prophylaxis. CONCLUSIONS: Our findings highlight the need to provide feedback to all levels of perioperative care providers involved in patient care. Future research in this area should report implementation parameters in more detail.

PURPOSE: Genomic tests improve accuracy of risk prediction for early breast cancers but these are expensive. This study evaluated the clinical utility of EndoPredict®, in terms of impact on adjuvant therapy recommendations and identification of parameters to guide selective application. METHODS: Patients with ER-positive, HER2-negative, and early-stage invasive breast cancer were tested with EndoPredict®. Two cohorts were recruited: one consecutively and another at clinical team discretion. Systemic treatment recommendations were recorded before and after EndoPredict® results were revealed to the multidisciplinary team. RESULTS: 233 patients were recruited across five sites: 123 consecutive and 110 at clinical team discretion. In the consecutive cohort 50.6% (62/123) cases were classified high risk of recurrence by EndoPredict®, compared with 62.7% (69/110) in the selective cohort. A change in treatment recommendation was significantly more likely (p < 0.0001) in the selective cohort (43/110, 39.1%) compared to the consecutive group (11/123, 8.9%). The strongest driver of selective recruitment was intermediate grade histology, whilst logistic regression modelling demonstrated that nodal status (p < 0.001), proliferative rate (p = 0.001), and progesterone receptor positivity (p < 0.001) were the strongest discriminators of risk. CONCLUSION: Whilst molecular risk can be predicted by traditional variables in a high proportion of cases, EndoPredict® had a greater impact on treatment decisions in those cases selected for testing at team discretion. This is indicative of the robust ability of the clinical team to identify cases most likely to benefit from testing, underscoring the value of genomic tests in the oncologists' tool kit.

OBJECTIVE: This study aimed to gain insight into decision-making strategies individuals used when evaluating pairs of SF-6Dv2 health states in discrete choice experiments (DCEs). METHODS: This qualitative, cross-sectional, noninterventional study asked participants to use a think-aloud approach to compare SF-6Dv2 health states in DCEs. Thematic analysis focused on comprehension and cognitive strategies used to compare health states and make decisions. RESULTS: Participants (N = 40) used 3 main strategies when completing DCEs: (1) trading, (2) reinterpretation, and (3) relying on previous experience. Trading was the most common strategy, used by everyone at least once, and involved prioritizing key attributes, such as preferring a health state with significant depression but no bodily pain. Reinterpretation was used by 17 participants and involved reconstructing health states by changing underlying assumptions (eg, rationalizing selecting a health state with significant pain because they could take pain medications). Finally, some (n = 13) relied on previous experience when making decisions on some choice tasks. Participants with experience dealing with pain, for instance, prioritized health states with the least impact in this dimension. CONCLUSIONS: Qualitatively evaluating the decision-making strategies used in DCEs allows researchers to evaluate whether the tasks and attributes are interpreted accurately. The findings from this study add to the understanding of the generation of SF-6Dv2 health utility weights and the validity of these weights (e.g., reinterpreting health states could undermine the validity of DCEs and utility weights), and the overall usefulness of the SF-6Dv2. The methodology described in this study can and should be carried forth in valuing other health utility measures, not just the SF-6Dv2.

Infants born with low or high ("at-risk") birthweights are at greater risk of adverse health outcomes across the life course. Our objective was to examine whether geographic hotspots of low and high birthweight prevalence in New York City had different patterns of neighborhood risk factors. We performed census tract-level geospatial clustering analyses using (1) birthweight prevalence and maternal residential address from an all-payer claims database and (2) domains of neighborhood risk factors (socioeconomic and food environment) from national and local datasets. We then used logistic regression analysis to identify specific neighborhood risk factors associated with low and high birthweight hotspots. This study examined 2088 census tracts representing 419,025 infants. We found almost no overlap (1.5%) between low and high birthweight hotspots. The majority of low birthweight hotspots (87.2%) overlapped with a socioeconomic risk factor and 95.7% overlapped with a food environment risk factor. Half of high birthweight hotspots (50.0%) overlapped with a socioeconomic risk factor and 48.8% overlapped with a food environment risk factor. Low birthweight hotspots were associated with high prevalence of excessive housing cost, unemployment, and poor food environment. High birthweight hotspots were associated with high prevalence of uninsured persons and convenience stores. Programs and policies that aim to prevent disparities in infant birthweight should examine the broader context by which hotspots of at-risk birthweight overlap with neighborhood risk factors. Multi-level strategies that include the neighborhood context are needed to address prenatal pathways leading to low and high birthweight outcomes.

OBJECTIVE: To compare differences in healthcare utilization and costs for Medicaid-insured children with medical complexity (CMC) by race/ethnicity and rurality. METHODS: Retrospective cohort of North Carolina (NC) Medicaid claims for children 3-20 years old with 3 years continuous Medicaid coverage (10/1/2015-9/30/2018). Exposures were medical complexity, race/ethnicity, and rurality. Three medical complexity levels were: without chronic disease, non-complex chronic disease, and complex chronic disease; the latter were defined as CMC. Race/ethnicity was self-reported in claims; we defined rurality by home residence ZIP codes. Utilization and costs were summarized for 1 year (10/1/2018-9/30/2019) by complexity level classification and categorized as acute care (hospitalization, emergency [ED]), outpatient care (primary, specialty, allied health), and pharmacy. Per-complexity group utilization rates (per 1000 person-years) by race/ethnicity and rurality were compared using adjusted rate ratios (ARR). RESULTS: Among 859,166 Medicaid-insured children, 118,210 (13.8%) were CMC. Among CMC, 36% were categorized as Black non-Hispanic, 42.7% White non-Hispanic, 14.3% Hispanic, and 35% rural. Compared to White non-Hispanic CMC, Black non-Hispanic CMC had higher hospitalization (ARR = 1.12; confidence interval, CI 1.08-1.17) and ED visit (ARR = 1.17; CI 1.16-1.19) rates; Hispanic CMC had lower ED visit (ARR = 0.77; CI 0.75-0.78) and hospitalization rates (ARR = 0.79; CI 0.73-0.84). Black non-Hispanic and Hispanic CMC had lower outpatient visit rates than White non-Hispanic CMC. Rural CMC had higher ED (ARR = 1.13; CI 1.11-1.15) and lower primary care utilization rates (ARR = 0.87; CI 0.86-0.88) than urban CMC. DISCUSSION: Healthcare utilization varied by race/ethnicity and rurality for Medicaid-insured CMC. Further studies should investigate mechanisms for these variations and expand higher value, equitable care delivery for CMC.

Genomic resources for the domestic dog have improved with the widespread adoption of a 173k SNP array platform and updated reference genome. SNP arrays of this density are sufficient for detecting genetic associations within breeds but are underpowered for finding associations across multiple breeds or in mixed-breed dogs, where linkage disequilibrium rapidly decays between markers, even though such studies would hold particular promise for mapping complex diseases and traits. Here we introduce an imputation reference panel, consisting of 365 diverse, whole-genome sequenced dogs and wolves, which increases the number of markers that can be queried in genome-wide association studies approximately 130-fold. Using previously genotyped dogs, we show the utility of this reference panel in identifying potentially novel associations, including a locus on CFA20 significantly associated with cranial cruciate ligament disease, and fine-mapping for canine body size and blood phenotypes, even when causal loci are not in strong linkage disequilibrium with any single array marker. This reference panel resource will improve future genome-wide association studies for canine complex diseases and other phenotypes.

OBJECTIVES: To identify the implementation strategies used in World Health Organization Surgical Safety Checklist (SSC) uptake in low- and middle-income countries (LMICs); examine any association of implementation strategies with implementation effectiveness; and to assess the clinical impact. BACKGROUND: The SSC is associated with improved surgical outcomes but effective implementation strategies are poorly understood. METHODS: We searched the Cochrane library, MEDLINE, EMBASE and PsycINFO from June 2008 to February 2019 and included primary studies on SSC use in LMICs. Coprimary objectives were identification of implementation strategies used and evaluation of associations between strategies and implementation effectiveness. To assess the clinical impact of the SSC, we estimated overall pooled relative risks for mortality and morbidity. The study was registered on PROSPERO (CRD42018100034). RESULTS: We screened 1562 citations and included 47 papers. Median number of discrete implementation strategies used per study was 4 (IQR: 1-14, range 0-28). No strategies were identified in 12 studies. SSC implementation occurred with high penetration (81%, SD 20%) and fidelity (85%, SD 13%), but we did not detect an association between implementation strategies and implementation outcomes. SSC use was associated with a reduction in mortality (RR 0.77; 95% CI 0.67-0.89), all complications (RR 0.56; 95% CI 0.45-0.71) and infectious complications (RR 0.44; 95% CI 0.37-0.52). CONCLUSIONS: The SSC is used with high fidelity and penetration is associated with improved clinical outcomes in LMICs. Implementation appears well supported by a small number of tailored strategies. Further application of implementation science methodology is required among the global surgical community.

BACKGROUND AND AIMS: Skeletal muscle index (SMI) from computed tomography (CT) reliably assesses sarcopenia, however, it is expensive and involves serial radiation exposure. Phase angle (PhA) from bioimpedance analysis (BIA) is a noninvasive, low cost, bedside nutritional tool used to monitor changes to nutritional interventions. We aimed to compare the performance of PhA with SMI to assess sarcopenia in cirrhosis. METHODS: Ambispective cohort study. Consecutive patients with cirrhosis and available images from abdominal CT scan were included. Monofrequency BIA was performed within 2 weeks CT. Spearman's correlation, ROC curve, and survival analysis with Kaplan-Meier, Cox and competing-risk regression were performed. RESULTS: 136 patients were included with a mean age of 54.5 years (60% female). Most had decompensated disease (66%) with ascites in 47%, and a mean MELD of 14 ± 6. We found positive correlations between SMI and PhA (r = 0.58 , P < .001), irrespective of the presence of ascites. The AUROC of PhA-sarcopenia in all patients was 0.702; (0.748 in males,0.677 in females). The best cutoffs of PhA for diagnosing sarcopenia were ≤5.6° in males and ≤5.4° in females. SMI and PhA were significantly associated with survival in Kaplan-Meier curves. In multivariable analyses, SMI was outperformed by age and MELD, whereas PhA remained independently associated with mortality. Considering transplantation as a competing risk, regression analysis showed both SMI and PhA to be independent predictors of mortality (sHR:0.95 [0.90-0.99] and sHR:0.61 [0.42-0.88]). CONCLUSION: PhA moderately correlates with SMI for the identification of sarcopenia in patients with cirrhosis. However, its prognostic accuracy is comparable to that of SMI, and it is not influenced by ascites.

BACKGROUND: The enhanced knowledge of cancer biology has led to considerable advancement in systemic therapy for advanced breast cancer. Recently, studies showed that cyclin-dependent kinase (CDK) 4/6 inhibitor, when added to endocrine therapy, had improved the outcomes of patients with advanced ER-positive HER2-negative breast cancer. However, the disease often progresses following a period of treatment response. In a subset of patients, disease progression may occur at limited sites, i.e., oligoprogressive disease (OPD). In the past few years, stereotactic radiotherapy (SRT) has emerged as a safe and effective treatment for advanced cancer when delivered to limited metastatic sites. Hence, it is worth investigating the role of SRT in the setting of oligoprogressive breast cancer. METHOD: AVATAR is a multicentre phase II registry trial of SRT with endocrine therapy and CDK 4/6 inhibitor for the management of advanced ER-positive HER2-negative breast cancer. The study aims to enrol 32 patients with OPD limited to 5 lesions. The primary endpoint of the study is time to change systemic therapy measured from the commencement of SRT to change in systemic therapy. Secondary objectives include overall survival, progression free survival and treatment related toxicity. The exploratory objective is to describe the time to change in systemic therapy by the site (bone only vs. non-bone lesions) and number (1 vs. > 1) of OPD. DISCUSSION: This study aims to explore the effect of SRT in maximising the benefit of systemic therapy in patients with oligoprogressive ER-positive HER2-negative breast cancer. This approach might help reduce the burden of disease and improve the life quality in these patients. TRIAL REGISTRATION: ACTRN, ACTRN12620001212943 .

BACKGROUND: Patients with sickle cell disease (SCD) experience daily pain and acute episodes known as sickle cell pain crises (SCPCs). The Sickle Cell Pain Diary-Caregiver Report (SCPD-C) is an observer-reported diary for use by caregivers of children ages < 12 years with SCD. This study reports on the content validity of the SCPD-C. METHODS: The SCPD-C was developed based on a literature review, measurement expert input, and a patient advisory board including clinicians. Three rounds of interviews (including both concept elicitation and cognitive debriefing methodologies) were conducted with caregivers of children with SCD aged < 12 to evaluate the content validity of the SCPD-C. RESULTS: Across three rounds of interviews, caregivers confirmed concepts in the SCPD-C and described observed impacts that were important and were added. Overall, caregivers evaluated the SCPD-C as easy to understand, with some minor adaptations for clarity. Additionally, the diary was split into two versions based on the child's age and school enrollment status (SCPD-CS for school-aged and SCPD-CN for non-school age children). CONCLUSIONS: Caregivers provided valuable input that led to important additions and changes to the measures. The SCPD-CS and SCPD-CN are appropriate and fit-for-purpose observer-reported outcome measures of SCPC-related pain frequency and severity, and impacts on health-related quality of life.

BACKGROUND: AA living in rural areas of the southeastern U.S. experience a disproportionate burden of cardiovascular disease (CVD) morbidity and mortality. Neighborhood environmental factors contribute to this disparity and may decrease the effectiveness of lifestyle interventions aimed at preventing CVD. Furthermore, the influence of neighborhood factors on AA CVD risk behaviors (i.e. physical activity) may be obscured by the use of researcher-defined neighborhoods and researcher-defined healthy and unhealthy places. The objective of this study was to elucidate the effects of neighborhood environments on AA CVD risk behaviors among AA adults who recently completed a lifestyle intervention. We specifically sought to identify AA adults' self-perceived places of significance and their perceptions of how these places impact CVD risk behaviors including diet, physical activity and smoking. METHODS: We conducted semi-structured interviews with AA adults (N = 26) living in two rural North Carolina counties (Edgecombe and Nash, North Carolina, USA). Participants were recruited from a community-based behavioral CVD risk reduction intervention. All had at least one risk factor for CVD. Participants identified significant places including where they spent the most time, meaningful places, and healthy and unhealthy places on local maps. Using these maps as a reference, participants described the impact of each location on their CVD risk behaviors. Data were transcribed verbatim and coded using NVivo 12. RESULTS: The average age of participants was 63 (SD = 10) and 92% were female. Places participants defined as meaningful and places where they spent the most time included churches and relatives' homes. Healthy places included gyms and parks. Unhealthy places included fast food restaurants and relatives' homes where unhealthy food was served. Place influenced CVD risk behaviors in multiple ways including through degree of perceived control over the environment, emotional attachment and loneliness, caretaking responsibilities, social pressures and social support. CONCLUSIONS: As we seek to improve cardiovascular interventions for rural AA in the American South, it will be important to further assess the effect of significant places beyond place of residence. Strategies which leverage or modify behavioral influences within person-defined significant places may improve the reach and effectiveness of behavioral lifestyle interventions.

PURPOSE: Compare outcomes of stapes mobilization and stapedectomy performed by a single surgeon for the otosclerosis. MATERIALS AND METHODS: A retrospective chart review of adult patients who underwent stapes mobilization or stapedectomy for otosclerosis was performed. Operative notes reviewed; patients included if diagnosed with otosclerosis without another otologic disease that could contribute to their hearing loss and all required data were available. Pre-and post-operative audiograms at 1, 6, and 12-months were evaluated to compare the air-bone gaps between the mobilization and stapedectomy procedures. The rates of sensorineural hearing loss also were compared. Student t-tests and multiple regression models were used to ascertain the association between improvement in post-operative air-bone gaps, sensorineural hearing loss, and the procedure undertaken. RESULTS: Sixty-seven (n = 67) patients with 108 procedures were included for analysis. No substantial difference between the surgical subgroups was found when comparing stapes mobilization to stapedectomy, and there was no evidence to suggest that either surgical procedure was superior to the other based on the data obtained and analyzed. Improvements in air-bone gap averaged 15.79 dB for stapes mobilization and 19.23 dB for stapedectomy. The results of the study showed no evidence of post-operative sensorineural hearing loss or change in air-bone gaps when comparing virgin to "revision" stapedectomy largely in patients who had failed previous mobilization. CONCLUSION: Stapes mobilization provides a conservative approach to otosclerosis patients suffering from conductive hearing loss. Stapedectomy can be used to correct failed mobilization.

Children with LI are at a disadvantage because they typically have smaller vocabularies than their TD peers. However, children from low-SES households often also have smaller vocabularies and can thus be misdiagnosed with LI. The purpose of this study was to compare the fast-mapping (FM) skills of 3 groups of 4- to 9-year-olds: typically developing (TD) children with low socioeconomic status (SES) and mid SES, and mid-SES children with language impairment (LI), to ascertain whether FM is affected by SES. The FM items of the Diagnostic Evaluation of Language Variation were administered to 253 TD mid-SES children, 75 TD low-SES children, and 36 children with LI. On FM with novel verbs, the TD groups differed significantly (p = .001) as did the TD mid-SES and LI groups (p = .046), but not the TD low-SES and LI groups (p = 1.00). On a comparable task with real verbs, the TD mid-SES group also differed significantly from the TD low-SES (p < .001) and LI group (p = .018), with no significant difference between the latter two groups (p = 1.00). FM has been proposed as a non-SES-sensitive measure but, unlike previous studies, we found FM to be affected by SES, rendering it an insufficiently unbiased measure for our sample of children. Further thought should be given to measures that can successfully differentiate between children with LI, and children from low-SES backgrounds, possibly rendering scores adjusted for SES, so that targeted intervention can be offered.

A large number of children worldwide are only exposed to their L2 around 3 years of age and can exhibit linguistic behaviours that resemble those of a child with Developmental Language Disorder (DLD). This can lead to under- or over-identification of DLD in this population. This study endeavors to contribute to overcoming this problem, by determining whether two specific clinical markers used with the Italian monolingual population can also be used with early L2 acquiring children, namely clitic production and non-word repetition. Our study involved two groups of 5-year-old L2 learners of Italian from various language backgrounds; 18 children had been referred to Speech and Language Therapy (SLT) services (EL2_DLD), and 30 children were typically developing (EL2_TD). The participants completed an Italian clitic production task and a non-word repetition task based on Italian phonotactics. Data was also collected from the participants' caregivers with the ALDeQ Parental Questionnaire to obtain information about the children's L1. Our results suggest that non-word repetition and clitic production in Italian are potentially useful for identifying L2 learners of Italian with DLD, at the age of 5 years. The repetition of non-words is highly accurate in identifying children with DLD among the participants, while clitic production is somewhat less discriminative in this sample. This study is a first step towards uncovering clinical markers that could be used to determine the presence of DLD in children acquiring their L2.

INTRODUCTION: A decline in physical function is highly prevalent and a poor prognostic factor in cirrhosis. We assessed the benefits of a home-based physical activity program (HB-PAP) in patients with cirrhosis with a randomized pilot trial. METHODS: All participants received a personal activity tracker to monitor daily activities and were given 12 g/day of an essential amino acid supplement. The HB-PAP intervention consisted of biweekly counseling sessions to increase physical activity for 12 weeks. Six-minute walk test (6MWT) and cardiopulmonary exercise testing (CPET) assessed changes in aerobic fitness. Different anthropometric measuring tools were used for skeletal muscle and adiposity assessment. RESULTS: Seventeen patients (60% male; 29% nonalcoholic steatohepatitis/cryptogenic, 29% hepatitis C, 24% alcohol, 18% other) were randomized, 9 to HB-PAP group. There were no significant differences in MELD-sodium between HB-PAP and controls at baseline or after the 12-week intervention. By the end of study, there was a significant between-group difference in daily step count favoring the active group (2627 [992-4262], p = 0.001), with less sedentary patients in the active group (33-17% vs. 25-43%, p = 0.003). The 6MWT improved in the HB-PAP group (423 ± 26 m vs. 482 ± 35 m), while the controls had a nonsignificant drop (418 ± 26 m vs. 327 ± 74 m) with a significant between-group difference. CPET did not change. Other than an improvement in psoas muscle index, there were no differences in anthropometry, or in quality of life. CONCLUSIONS: HB-PAP maintained physical performance and improved aerobic fitness according to 6MWT but not CPET, supporting the use of personal activity trackers to monitor/guide home-based prehabilitation programs in cirrhosis.
