Biomechanical comparison of open Bankart repair vs. conjoint tendon transfer in a 10% anterior glenoid bone loss shoulder instability model.

BACKGROUND: The treatment of shoulder instability in patients with subcritical glenoid bone loss poses a difficult problem for surgeons as new evidence supports a higher failure rate when a standard arthroscopic Bankart repair is used. The purpose of this study was to compare a conjoint tendon transfer (soft-tissue Bristow) to an open Bankart repair in a cadaveric instability model of 10% glenoid bone loss. METHODS: Eight cadaveric shoulders were tested using a custom testing system that allows for a 6-degree-of-freedom positioning of the glenohumeral joint. The rotator cuff muscles were loaded to simulate physiologic muscle conditions. Four conditions were tested: (1) intact, (2) Bankart lesion with 10% bone loss, (3) conjoint tendon transfer, and (4) open Bankart repair. Range of motion, glenohumeral kinematics, and anterior-inferior translation at 60° of external rotation with 20 N, 30 N, and 40 N were measured in the scapular and coronal planes. Glenohumeral joint translational stiffness was calculated as the linear fit of the translational force-displacement curve. Force to anterior-inferior dislocation was also measured in the coronal plane. Repeated measures analysis of variance with a Bonferroni correction was used for statistical analysis. RESULTS: A Bankart lesion with 10% bone loss increased the range of motion in both the scapular (P = .001) and coronal planes (P = .001). The conjoint tendon transfer had a minimal effect on the range of motion (vs. intact P = .019, .002), but the Bankart repair decreased the range of motion to intact (P = .9, .4). There was a significant decrease in glenohumeral joint translational stiffness for the Bankart lesion compared with intact in the coronal plane (P = .021). The conjoint tendon transfer significantly increased stiffness in the scapular plane (P = .034), and the Bankart repair increased stiffness in the coronal plane (P = .037) compared with the Bankart lesion. The conjoint tendon transfer shifted the humeral head posteriorly at 60° and 90° of external rotation in the scapular plane. The Bankart repair shifted the head posteriorly in maximum external rotation in the coronal plane. There was no significant difference in force to dislocation between the Bankart repair (75.8 ± 6.6 N) and the conjoint tendon transfer (66.5 ± 4.4 N) (P = .151). CONCLUSION: In the setting of subcritical bone loss, both the open Bankart repair and conjoint tendon transfer are biomechanically viable options for the treatment of anterior shoulder instability; further studies are needed to extrapolate these data to the clinical setting.

Safety and Immunogenicity of an Investigational Respiratory Syncytial Virus Vaccine (RSVPreF3) in Mothers and Their Infants: A Phase 2 Randomized Trial.

BACKGROUND: In a phase 1/2 study, a maternal respiratory syncytial virus vaccine candidate (RSVPreF3) demonstrated an acceptable safety profile and efficiently increased RSV-specific humoral immune responses in non-pregnant women. METHODS: In this phase 2 observer-blind, placebo-controlled, randomized clinical trial (NCT04126213), the safety of RSVPreF3 (60 or 120 µg), administered during late second or third trimester, was evaluated in 213 18- to 40-year-old healthy pregnant women through 6 months postdelivery and their offspring through infancy; immunogenicity was evaluated through day 43 postdelivery and day 181 postbirth, respectively. RESULTS: RSVPreF3 was well tolerated. No pregnancy-related or neonatal adverse events of special interest were considered vaccine/placebo related. In the 60 and 120 µg RSVPreF3 groups: (1) neutralizing antibody (nAb) titers in mothers increased 12.7- and 14.9-fold against RSV-A and 10.6- and 13.2-fold against RSV-B, respectively, 1 month postvaccination and remained 8.9-10.0-fold over prevaccination at day 43 postdelivery; (2) nAb titers were consistently higher compared to placebo recipients; (3) placental transfer ratios for anti-RSVPreF3 antibodies at birth were 1.62 and 1.90, respectively, and (4) nAb levels in infants were highest at birth and declined through day 181 postbirth. CONCLUSIONS: RSVPreF3 maternal vaccination had an acceptable safety risk profile and induced robust RSV-specific immune responses with successful antibody transfer to their newborns. CLINICAL TRIALS REGISTRATION: NCT04126213.

WHAT IS THE CONTEXT?: Infants, especially those less than 6 months of age, are at increased risk of lung infection caused by respiratory syncytial virus (RSV). However, this risk could be reduced with maternal vaccination against RSV during pregnancy. A previous clinical trial found that a vaccine candidate (named RSVPreF3) was well tolerated when given to non-pregnant women. WHAT IS NEW?: In pregnant women, RSVPreF3 was also well tolerated. Occurrence of unsolicited adverse events was similar between vaccine and placebo recipients. None of the serious adverse events or events of interest for pregnant women or newborns were considered related to the study intervention. One month after vaccination, mothers who received RSVPreF3 had 11­15 times higher levels of antibodies against RSV than before vaccination. These antibody levels remained similar until 43 days after delivery. In the infants born to mothers vaccinated during pregnancy with RSVPreF3, antibody levels were highest at birth, when levels were higher than in their mothers, and declined through day 181 postbirth. WHAT IS THE IMPACT?: RSVPreF3 had an acceptable safety risk profile in pregnant women and their babies. This vaccine induced potent immune responses against RSV, with maternal antibodies transferred to infants of the vaccinated mothers.

Creating profiles of juvenile offenders using functions of aggression and callous-unemotional traits: relations to crime type.

A rich line of criminological theories and research has suggested that individual characteristics may be important to predicting criminal activity. However, there is limited research examining how individual characteristics may be related to the type of crime committed (e.g. violent, sex, drug). To provide guidance to these questions, the current set of two studies used latent profile analysis to identify groups of offenders based on individual factors (i.e. proactive and reactive aggression, and callous-unemotional traits), chosen for their interrelatedness and their established associations with crime, and examined whether these groups relate to type, severity or the number of crimes committed across two studies. In both studies, four groups of offenders were identified, but these groups were not associated with offending behaviors or patterns. Findings and implications are discussed.

Interventions to prevent women from developing gestational diabetes mellitus: an overview of Cochrane Reviews.

BACKGROUND: The prevalence of gestational diabetes mellitus (GDM) is increasing, with approximately 15% of pregnant women affected worldwide, varying by country, ethnicity and diagnostic thresholds. There are associated short- and long-term health risks for women and their babies. OBJECTIVES: We aimed to summarise the evidence from Cochrane systematic reviews on the effects of interventions for preventing GDM. METHODS: We searched the Cochrane Database of Systematic Reviews (6 August 2019) with key words 'gestational diabetes' OR 'GDM' to identify reviews pre-specifying GDM as an outcome. We included reviews of interventions in women who were pregnant or planning a pregnancy, irrespective of their GDM risk status. Two overview authors independently assessed eligibility, extracted data and assessed quality of evidence using ROBIS and GRADE tools. We assigned interventions to categories with graphic icons to classify the effectiveness of interventions as: clear evidence of benefit or harm (GRADE moderate- or high-quality evidence with a confidence interval (CI) that did not cross the line of no effect); clear evidence of no effect or equivalence (GRADE moderate- or high-quality evidence with a narrow CI crossing the line of no effect); possible benefit or harm (low-quality evidence with a CI that did not cross the line of no effect or GRADE moderate- or high-quality evidence with a wide CI); or unknown benefit or harm (GRADE low-quality evidence with a wide CI or very low-quality evidence). MAIN RESULTS: We included 11 Cochrane Reviews (71 trials, 23,154 women) with data on GDM. Nine additional reviews pre-specified GDM as an outcome, but did not identify GDM data in included trials. Ten of the 11 reviews were judged to be at low risk of bias and one review at unclear risk of bias. Interventions assessed included diet, exercise, a combination of diet and exercise, dietary supplements, pharmaceuticals, and management of other health problems in pregnancy. The quality of evidence ranged from high to very low. Diet Unknown benefit or harm: there was unknown benefit or harm of dietary advice versus standard care, on the risk of GDM: risk ratio (RR) 0.60, 95% CI 0.35 to 1.04; 5 trials; 1279 women; very low-quality evidence. There was unknown benefit or harm of a low glycaemic index diet versus a moderate-high glycaemic index diet on the risk of GDM: RR 0.91, 95% CI 0.63 to 1.31; 4 trials; 912 women; low-quality evidence. Exercise Unknown benefit or harm: there was unknown benefit or harm for exercise interventions versus standard antenatal care on the risk of GDM: RR 1.10, 95% CI 0.66 to 1.84; 3 trials; 826 women; low-quality evidence. Diet and exercise combined Possible benefit: combined diet and exercise interventions during pregnancy versus standard care possibly reduced the risk of GDM: RR 0.85, 95% CI 0.71 to 1.01; 19 trials; 6633 women; moderate-quality evidence. Dietary supplements Clear evidence of no effect: omega-3 fatty acid supplementation versus none in pregnancy had no effect on the risk of GDM: RR 1.02, 95% CI 0.83 to 1.26; 12 trials; 5235 women; high-quality evidence. Possible benefit: myo-inositol supplementation during pregnancy versus control possibly reduced the risk of GDM: RR 0.43, 95% CI 0.29 to 0.64; 3 trials; 502 women; low-quality evidence. Possible benefit: vitamin D supplementation versus placebo or control in pregnancy possibly reduced the risk of GDM: RR 0.51, 95% CI 0.27 to 0.97; 4 trials; 446 women; low-quality evidence. Unknown benefit or harm: there was unknown benefit or harm of probiotic with dietary intervention versus placebo with dietary intervention (RR 0.37, 95% CI 0.15 to 0.89; 1 trial; 114 women; very low-quality evidence), or probiotic with dietary intervention versus control (RR 0.38, 95% CI 0.16 to 0.92; 1 trial; 111 women; very low-quality evidence) on the risk of GDM. There was unknown benefit or harm of vitamin D + calcium supplementation versus placebo (RR 0.33, 95% CI 0.01 to 7.84; 1 trial; 54 women; very low-quality evidence) or vitamin D + calcium + other minerals versus calcium + other minerals (RR 0.42, 95% CI 0.10 to 1.73; 1 trial; 1298 women; very low-quality evidence) on the risk of GDM. Pharmaceutical Possible benefit: metformin versus placebo given to obese pregnant women possibly reduced the risk of GDM: RR 0.85, 95% CI 0.61 to 1.19; 3 trials; 892 women; moderate-quality evidence. Unknown benefit or harm:eight small trials with low- to very low-quality evidence showed unknown benefit or harm for heparin, aspirin, leukocyte immunisation or IgG given to women with a previous stillbirth on the risk of GDM. Management of other health issues Clear evidence of no effect: universal versus risk based screening of pregnant women for thyroid dysfunction had no effect on the risk of GDM: RR 0.93, 95% CI 0.70 to 1.25; 1 trial; 4516 women; moderate-quality evidence. Unknown benefit or harm: there was unknown benefit or harm of using fractional exhaled nitrogen oxide versus a clinical algorithm to adjust asthma therapy on the risk of GDM: RR 0.74, 95% CI 0.31 to 1.77; 1 trial; 210 women; low-quality evidence. There was unknown benefit or harm of pharmacist led multidisciplinary approach to management of maternal asthma versus standard care on the risk of GDM: RR 5.00, 95% CI 0.25 to 99.82; 1 trial; 58 women; low-quality evidence. AUTHORS' CONCLUSIONS: No interventions to prevent GDM in 11 systematic reviews were of clear benefit or harm. A combination of exercise and diet, supplementation with myo-inositol, supplementation with vitamin D and metformin were of possible benefit in reducing the risk of GDM, but further high-quality evidence is needed. Omega-3-fatty acid supplementation and universal screening for thyroid dysfunction did not alter the risk of GDM. There was insufficient high-quality evidence to establish the effect on the risk of GDM of diet or exercise alone, probiotics, vitamin D with calcium or other vitamins and minerals, interventions in pregnancy after a previous stillbirth, and different asthma management strategies in pregnancy. There is a lack of trials investigating the effect of interventions prior to or between pregnancies on risk of GDM.

Arthroscopic Vastus Elevation (AVE) for Arthrofibrosis of the Knee: Surgical Technique and Literature Review.

Arthrofibrosis of the knee continues to challenge Orthopaedic surgeons. With a wide etiology, lack of knee motion can be debilitating. Its surgical management has several complications. The purpose of this study is to describe a modification of previously described techniques to aid in the management of knee arthrofibrosis. Arthroscopic vastus elevation in conjunction with adjuvant hemostatic agents allows for a controlled quadriceps elevation in the setting of arthrofibrosis. In addition to a thorough intra-articular lysis of adhesions, this appears to improve motion, while minimizing postoperative complications. Minimized postoperative complications include extensor lag, skin necrosis, and bleeding complications. (Journal of Surgical Orthopaedic Advances 29(2):117-120, 2020).

Factors associated with perceived containment.

There is growing evidence indicating that a lack of perceived containment, or youth's beliefs about whether adults can control their behavior, is associated with problem behavior. However, little research has examined factors that may contribute to perceived containment, which would be helpful in further tailoring prevention and intervention efforts for problem behavior. The current study evaluated associations between callous-unemotional (C/U) traits, peer delinquency, neighborhood problems, and perceived containment. Associations were examined using a sample of detained youth. Findings indicated that while all three factors were correlated with perceived containment, only C/U traits (particularly the callousness and uncaring subscales) and peer delinquency were uniquely associated with perceived containment. Further, C/U traits did not moderate the links between peer delinquency or neighborhood problems and perceived containment. This study supports the influence of both individual and contextual factors on perceived containment, suggesting multiple factors to target for prevention and intervention.

Relationship between BMI and adiposity among different ethnic groups in 2-year-old New Zealand children.

Age- and sex-based BMI cut-offs are used to define overweight and obesity, but the relationship between BMI and body composition has not been very well studied in children or compared between children of different ethnic groups. Body size and composition in childhood are also influenced by size at birth. Our aim was to compare body size and composition at 2 years in children with different ethnicity and size at birth. We prospectively followed a multi-ethnic cohort of 300 children born with risk factors for neonatal hypoglycaemia (infants of diabetics, large or small at birth or late preterm) to 2 years corrected age. Complete data on weight, height and head circumference and body composition using bioelectrical impedance 24±1 months corrected age were available in 209 children. At birth, compared with European children, Chinese, Indian and other ethnicity children were lighter, and Indian children had smaller head circumferences, but birth lengths were similar in all ethnic groups. At 2 years, Pacific children were heavier and had higher BMI z scores, and Indian children had smaller head circumferences and lower BMI z scores than those from other ethnic groups. However, fat mass and fat-free mass indices were similar in all groups. At median BMI, fat mass:fat-free mass ratio was 23 % lower in Pacific than in Indian children (0·22 v. 0·27, P=0·03). BMI is not a good indicator of adiposity in this multi-ethnic cohort of 2-year-old New Zealand children.

Vapocoolants (cold spray) for pain treatment during intravenous cannulation.

BACKGROUND: Intravenous cannulation is a painful procedure that can provoke anxiety and stress. Injecting local anaesthetic can provide analgesia at the time of cannulation, but it is a painful procedure. Topical anaesthetic creams take between 30 and 90 minutes to produce an effect. A quicker acting analgesic allows more timely investigation and treatment. Vapocoolants have been used in this setting, but studies have reported mixed results. OBJECTIVES: To determine effects of vapocoolants on pain associated with intravenous cannulation in adults and children. To explore variables that might affect the performance of vapocoolants, including time required for application, distance from the skin when applied and time to cannulation. To look at adverse effects associated with the use of vapocoolants. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Latin American Caribbean Health Sciences Literature (LILACS), the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Institute for Scientific Information (ISI) Web of Science and the http://clinicaltrials.gov/, http://www.controlled-trials.com/ and http://www.trialscentral.org/ databases to 1 May 2015. We applied no language restrictions. We also scanned the reference lists of included papers. SELECTION CRITERIA: We included all blinded and unblinded randomized controlled trials (RTCs) comparing any vapocoolant with placebo or control to reduce pain during intravenous cannulation in adults and children. DATA COLLECTION AND ANALYSIS: Three review authors independently assessed trial quality and extracted data, contacted study authors for additional information and assessed included studies for risk of bias. We collected and analysed data for the primary outcome of pain during cannulation, and for the secondary outcomes of pain associated with application of the vapocoolant, first attempt success rate of intravenous cannulation, adverse events and participant satisfaction. We performed subgroup analyses for the primary outcome to examine differences based on age of participant, type of vapocoolant used, application time of vapocoolant and clinical situation (emergency vs elective). We used random-effects model meta-analysis in RevMan 5.3 and assessed heterogeneity between trial results by examining forest plots and calculating the I(2) statistic. MAIN RESULTS: We found nine suitable studies of 1070 participants and included them in the qualitative analyses. We included eight studies of 848 participants in the meta-analysis for the primary outcome (pain during intravenous cannulation). Use of vapocoolants resulted in a reduction in pain scores as measured by a linear 100 mm visual analogue scale (VAS 100) compared with controls (difference between means -12.5 mm, 95% confidence interval (CI) -18.7 to -6.4 mm; moderate-quality evidence). We could not include in the meta-analysis one study, which showed no effects of the intervention.Use of vapocoolants resulted in increased pain scores at the time of application as measured by a VAS 100 compared with controls (difference between means 6.3 mm, 95% CI 2.2 to 10.3 mm; four studies, 461 participants; high-quality evidence) and led to no difference in first attempt success compared with controls (risk ratio (RR) 1.00, 95% CI 0.94 to 1.06; six studies, 812 participants; moderate-quality evidence). We documented eight minor adverse events reported in 279 vapocoolant participants (risk difference (RD) 0.03, 95% CI 0 to 0.05; five studies, 551 participants; low quality-evidence).The overall risk of bias of individual studies ranged from low to high, with high risk of bias for performance and detection bias in four studies. Sensitivity analysis showed that exclusion of studies at high or unclear risk of bias did not materially alter the results of this review. AUTHORS' CONCLUSIONS: Moderate-quality evidence indicates that use of a vapocoolant immediately before intravenous cannulation reduces pain during the procedure. Use of vapocoolant does not increase the difficulty of cannulation nor cause serious adverse effects but is associated with mild discomfort during application.

The longitudinal association of adverse events and working memory among preschoolers: A random-intercept cross-lag analysis.

OBJECTIVE: Past research examining the relation between adversity and working memory (WM) has found mixed results and has been limited by methodological issues (e.g., cross-sectional studies, limited measurement of adversity). The present study examined how adverse life events may impact WM among preschoolers who live in financially underresourced families and communities longitudinally over the course of 1 year. METHOD: The sample included 325 children (aged 3-5 at baseline), recruited because of their increased risk of exposure to high levels of adversity, and their primary caregivers. Children completed WM tasks and caregivers reported on their child's exposure to adverse events in the past 6 months across three time points, each time point occurring 6 months apart. Associations between adverse life events and WM over time were explored using a random-intercept cross-lagged panel model. RESULTS: No relations between preschoolers' adverse event exposure and WM (B = 0.05-0.75, p = .056-.764) were found across the three time points. CONCLUSION: Results indicated that at the individual level, when controlling for stable covariates, frequency of adverse life event exposure and WM abilities were unrelated to subsequent frequency of adverse event exposure and WM abilities. Findings suggest that WM may continue to develop typically, in the preschool years, despite exposure to adverse life events. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Effects of Parents' Adversity Exposure on General and Child-Specific Hostile Attribution Bias.

Hostile attribution bias (HAB), or the tendency to interpret others' intent as hostile, has been linked to a variety of maladaptive outcomes including aggression and harsh parenting practices. The current cross-sectional study examined the influence of parents' childhood and adulthood adversity exposure (i.e., frequency and polyvictimization) in the development of HAB. Parents of 324 preschool-age children answered questions about hypothetical social scenarios to examine their general hostile attributions of others, hostile attributions specific to their children, and their endorsement of aggressive responses as a behavioral solution to the scenario. Results from structural equation modeling indicated parents' frequency of adversity and polyvictimization in adulthood were each positively associated with both general and child-specific HAB. However, parents' childhood adversity polyvictimization was negatively associated with child-specific HAB. Further, neither childhood nor adulthood adversity exposure were significantly associated with aggressive responding. The results highlight the importance of adulthood adversity exposure in understanding the relation between adversity and HAB. Future directions and implications of these findings are discussed.

Telehealth Versus Face-to-face Psychotherapy for Less Common Mental Health Conditions: Systematic Review and Meta-analysis of Randomized Controlled Trials.

BACKGROUND: Mental disorders are a leading cause of distress and disability worldwide. To meet patient demand, there is a need for increased access to high-quality, evidence-based mental health care. Telehealth has become well established in the treatment of illnesses, including mental health conditions. OBJECTIVE: This study aims to conduct a robust evidence synthesis to assess whether there is evidence of differences between telehealth and face-to-face care for the management of less common mental and physical health conditions requiring psychotherapy. METHODS: In this systematic review, we included randomized controlled trials comparing telehealth (telephone, video, or both) versus the face-to-face delivery of psychotherapy for less common mental health conditions and physical health conditions requiring psychotherapy. The psychotherapy delivered had to be comparable between the telehealth and face-to-face groups, and it had to be delivered by general practitioners, primary care nurses, or allied health staff (such as psychologists and counselors). Patient (symptom severity, overall improvement in psychological symptoms, and function), process (working alliance and client satisfaction), and financial (cost) outcomes were included. RESULTS: A total of 12 randomized controlled trials were included, with 931 patients in aggregate; therapies included cognitive behavioral and family therapies delivered in populations encompassing addiction disorders, eating disorders, childhood mental health problems, and chronic conditions. Telehealth was delivered by video in 7 trials, by telephone in 3 trials, and by both in 1 trial, and the delivery mode was unclear in 1 trial. The risk of bias for the 12 trials was low or unclear for most domains, except for the lack of the blinding of participants, owing to the nature of the comparison. There were no significant differences in symptom severity between telehealth and face-to-face therapy immediately after treatment (standardized mean difference [SMD] 0.05, 95% CI -0.17 to 0.27) or at any other follow-up time point. Similarly, there were no significant differences immediately after treatment between telehealth and face-to-face care delivery on any of the other outcomes meta-analyzed, including overall improvement (SMD 0.00, 95% CI -0.40 to 0.39), function (SMD 0.13, 95% CI -0.16 to 0.42), working alliance client (SMD 0.11, 95% CI -0.34 to 0.57), working alliance therapist (SMD -0.16, 95% CI -0.91 to 0.59), and client satisfaction (SMD 0.12, 95% CI -0.30 to 0.53), or at any other time point (3, 6, and 12 months). CONCLUSIONS: With regard to effectively treating less common mental health conditions and physical conditions requiring psychological support, there is insufficient evidence of a difference between psychotherapy delivered via telehealth and the same therapy delivered face-to-face. However, there was no includable evidence in this review for some serious mental health conditions, such as schizophrenia and bipolar disorders, and further high-quality research is needed to determine whether telehealth is a viable, equivalent treatment option for these conditions.

Neurocognitive Outcomes at Age 2 Years After Neonatal Hypoglycemia in a Cohort of Participants From the hPOD Randomized Trial.

Importance: Neonatal hypoglycemia is common, but its association with later neurodevelopment is uncertain. Objective: To examine associations between neonatal hypoglycemia and neurocognitive outcomes at corrected age 2 years. Design, Setting, and Participants: Exploratory cohort analysis of the Hypoglycaemia Prevention With Oral Dextrose (hPOD) randomized clinical trial was conducted. The trial recruited participants from January 9, 2015, to May 5, 2019, with follow-up between January 26, 2017, and July 31, 2021. Infants were recruited from 9 maternity hospitals in New Zealand and assessed at home or in a research clinic. Children born late preterm and at term at risk of neonatal hypoglycemia but without evidence of acute or imminent illness in the first hour after birth were screened and treated to maintain blood glucose concentrations greater than or equal to 47 mg/dL. Exposures: Hypoglycemia was defined as any blood glucose concentration less than 47 mg/dL, recurrent as 3 or more episodes, and severe as less than 36 mg/dL. Main Outcomes and Measures: Neurologic examination and tests of development (Bayley III) and executive function. The primary outcome was neurosensory impairment (any of the following: blindness, deafness, cerebral palsy, developmental delay, or executive function total score worse than 1.5 SD below the mean). Results: A total of 1197 of 1321 (91%) eligible children were assessed at a mean of corrected age 24 months; 616 (52%) were male. Compared with the normoglycemia group, children who experienced hypoglycemia were more likely to have neurosensory impairment (111 [23%] vs 125 [18%]; adjusted risk ratio [aRR], 1.28; 95% CI, 1.01-1.60), particularly if they experienced severe episodes (30 [28%] vs 125 [18%]; aRR, 1.68; 95% CI, 1.20-2.36), but not recurrent episodes (12 [19%] vs 125 [18%]; aRR, 1.06; 95% CI, 0.63-1.80). The risk of cognitive, language, or motor delay was similar between groups, but children who experienced hypoglycemia had lower Bayley-III composite cognitive (adjusted mean difference [aMD], -1.48; 95% CI, -2.79 to -0.18) and motor scores (aMD, -2.05; 95% CI, -3.30 to -0.79). Conclusions and Relevance: In children born at risk of hypoglycemia but otherwise well, those who experienced neonatal hypoglycemia were more likely to have neurosensory impairment at corrected age 2 years, with higher risks after severe episodes. Further research is required to determine causality.

Safety and target engagement of an oral small-molecule sequestrant in adolescents with autism spectrum disorder: an open-label phase 1b/2a trial.

Autism spectrum disorder (ASD) is defined by hallmark behaviors involving reduced communication and social interaction as well as repetitive activities and restricted interests. ASD represents a broad spectrum, from minimally affected individuals to those requiring intense support, with additional manifestations often including anxiety, irritability/aggression and altered sensory processing. Gastrointestinal (GI) issues are also common in ASD, and studies have identified changes in the gut microbiome of individuals with ASD compared to control populations, complementing recent findings of differences in gut-derived metabolites in feces and circulation. However, a role for the GI tract or microbiome in ASD remains controversial. Here we report that an oral GI-restricted adsorbent (AB-2004) that has affinity for small aromatic or phenolic molecules relieves anxiety-like behaviors that are driven by a gut microbial metabolite in mice. Accordingly, a pilot human study was designed and completed to evaluate the safety of AB-2004 in an open-label, single-cohort, multiple-ascending-dose clinical trial that enrolled 30 adolescents with ASD and GI symptoms in New Zealand and Australia. AB-2004 was shown to have good safety and tolerability across all dose levels, and no drug-related serious adverse events were identified. Significant reductions in specific urinary and plasma levels of gut bacterial metabolites were observed between baseline and end of AB-2004 treatment, demonstrating likely target engagement. Furthermore, we observed improvements in multiple exploratory behavioral endpoints, most significantly in post hoc analysis of anxiety and irritability, as well as GI health, after 8 weeks of treatment. These results from an open-label study (trial registration no. ACTRN12618001956291) suggest that targeting gut-derived metabolites with an oral adsorbent is a safe and well-tolerated approach to improving symptoms associated with ASD, thereby emboldening larger placebo-controlled trials.

Return-to-Sport Criteria After Upper Extremity Surgery in Athletes-A Scoping Review, Part 2: Ulnar Collateral Ligament of the Elbow Procedures.

BACKGROUND: There is a lack of consensus to guide patient return to sport (RTS) after elbow ulnar collateral ligament surgery (eUCLS). PURPOSE: To describe the reported RTS criteria after eUCLS in the athletic population. STUDY DESIGN: Scoping review; Level of evidence, 4. METHODS: This scoping review was performed by adhering to the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Review) guidelines. We searched 5 electronic databases (MEDLINE, Scopus, SPORTDiscus, Embase, Google Scholar Advanced) and the gray literature for English-language studies that reported at least 1 RTS criterion in athletes after eUCLS. Data were extracted and summarized as frequencies or arithmetic mean and standard deviation. RESULTS: Included were 14 studies and 1335 athletes with a mean age of 21.4 ± 1.1 years. Time from surgery (range, 6-16 months) was the most common RTS criterion used, and it was reported by all 14 of the included articles. RTS criteria reported less often were pain (3/14; 21%), successful completion of a throwing program (3/14; 21%), muscle strength of the forearm muscles (1/14; 7%), and "normal" range of motion and muscle strength of the elbow and shoulder joints on the operated upper extremity (1/14; 7%). All studies used 1 to 5 of the above RTS criteria. CONCLUSION: Only 14 studies reported 1 or more RTS criteria after eUCLS in athletes, and time was the most common RTS criterion used. Our results highlight the need for a coordinated effort among surgeons, physical therapists, and athletic trainers in order to establish evidence-based RTS criteria after eUCLS in athletes so athletes can safely to sport and prolong their athletic careers.

Return-to-Sport Criteria After Upper Extremity Surgery in Athletes-A Scoping Review, Part 1: Rotator Cuff and Shoulder Stabilization Procedures.

BACKGROUND: Standardized criteria are lacking to guide patient return to sport (RTS) after rotator cuff surgery (RCS) or shoulder stabilization surgery (SSS). PURPOSE: To describe RTS criteria used after RCS and SSS in athletic populations. STUDY DESIGN: Scoping review; Level of evidence, 4. METHODS: This scoping review was based on the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Review) guidelines. A total of 5 electronic databases (MEDLINE, Scopus, SPORTDiscus, Embase, Google Scholar Advanced search) and the gray literature were searched for English-language studies that reported at least 1 RTS criterion in athletes after shoulder surgery. Studies were assigned to the RCS or SSS subgroup based on the primary procedure performed. Data were extracted and summarized as frequencies or arithmetic mean and standard deviation. RESULTS: Included were 52 studies and 2706 athletes (2206 male, 500 female, with a mean age of 28.8 ± 1.8 years). The RCS group consisted of 14 studies and the SSS group consisted of 38 studies. Time from surgery was the most common RTS criterion reported overall (37/52 studies; 71%) as well as within the RCS (93%) and SSS (63%) subgroups. Muscle strength (25/52 studies; 48%) and range of motion (23/52; 44%) were used by almost half of the included articles. RTS criteria reported less often were absence of pain, successful completion of sport-specific or position-specific test, proprioception, radiographic evaluation, patient-surgeon agreement, minimum time required to participate in pain-free throwing, and satisfactory scapulothoracic mechanics. All studies used 1 to 3 of the above RTS criteria; however, the definition of each criterion differed among the included articles. CONCLUSION: Time from surgery was the most commonly reported RTS criterion after RCS or SSS in athletes, whereas muscle strength and range of motion were used by almost half of the articles. There was high heterogeneity in the definition of each RTS criterion used among the included studies, which also used different combinations of 1 to 3 RTS criteria. These results suggest the need to better define quantitative and qualitative RTS criteria in athletes undergoing rotator cuff and shoulder stabilization procedures in order to safely return athletes to sport.

Two-year outcomes after dextrose gel prophylaxis for neonatal hypoglycaemia.

OBJECTIVE: To determine the effect of prophylactic dextrose gel for prevention of neonatal hypoglycaemia on neurodevelopment and executive function at 2 years' corrected age. DESIGN: Prospective follow-up of a randomised trial. SETTING: New Zealand. PATIENTS: Participants from the pre-hypoglycaemia Prevention with Oral Dextrose (pre-hPOD) trial randomised to one of four dose regimes of buccal 40% dextrose gel or equivolume placebo. MAIN OUTCOME MEASURES: Coprimary outcomes were neurosensory impairment and executive function. Secondary outcomes were components of the primary outcomes, neurology, anthropometry and health measures. RESULTS: We assessed 360 of 401 eligible children (90%) at 2 years' corrected age. There were no differences between dextrose gel dose groups, single or multiple dose groups, or any dextrose and any placebo groups in the risk of neurosensory impairment or low executive function (any dextrose vs any placebo neurosensory impairment: relative risk (RR) 0.77, 95% CI 0.50 to 1.19, p=0.23; low executive function: RR 0.50, 95% CI 0.24 to 1.06, p=0.07). There were also no differences between groups in any secondary outcomes. There was no difference between children who did or did not develop neonatal hypoglycaemia in the risk of neurosensory impairment (RR 1.05, 95% CI 0.68 to 1.64, p=0.81) or low executive function (RR 0.73, 95% CI 0.34 to 1.59, p=0.43). CONCLUSION: Prophylactic dextrose gel did not alter neurodevelopment or executive function and had no adverse effects to 2 years' corrected age, but this study was underpowered to detect potentially clinically important effects on neurosensory outcomes.

Open Brostrom for Lateral Ligament Stabilization.

PURPOSE OF REVIEW: Lateral ankle ligament sprains are one of the most commonly reported injuries in high-level athletes and the general population. Unfortunately, up to 40% of these can go on to develop chronic lateral ankle instability which in the right circumstances requires surgical intervention. The purpose of this review is to present the gold standard surgical treatment for chronic lateral instability with anatomic ligament repair and to highlight the techniques, outcomes, and importance of anatomy when considering surgical treatment. RECENT FINDINGS: Recent and remote literature agrees that the initial treatment for chronic ankle instability is non-operative rehabilitation. In the cases where this fails, the gold standard of surgical treatment is open anatomic repair using the Brostrom-Gould technique which stands out as having very good results over the course of time. Recent studies have shown equally good outcomes with arthroscopy as well as with internal brace devices, and both techniques show potential for earlier rehabilitation. In those with contraindications for anatomic repair including innate soft tissue laxity, high BMI, and in the revision setting, anatomic ligament reconstruction is an appropriate surgical option. Open modified Brostrom lateral ligament repair continues to be the preferred method of surgical treatment for chronic lateral ligament instability. In the setting of new modifications and techniques, long-term outcome studies are necessary to identify both their usefulness in long term and to compare them to the open surgery outcomes. It would be useful to standardize rehabilitation protocols as well as return to sport metrics in order to better evaluate outcomes moving forward.

Stress ulcer prophylaxis for non-critically ill patients on a teaching service.

RATIONALE: Doctors frequently give non-critically ill patients unjustified stress ulcer prophylaxis (SUP). It is unknown if this practice also occurs during residency training. OBJECTIVE: To evaluate the pattern of SUP given to non-critically ill medical patients on the teaching service of an internal medicine residency programme. METHODS: This was a retrospective cohort study of non-critically ill adults admitted to the internal medicine teaching service of a community hospital from August 2003 to July 2004. We assessed receipt of SUP, association of SUP with risk factors for stress ulcer bleeding; appropriateness of SUP according to evidence-based criteria; and incidence of stress ulcer bleeding. RESULTS: Of the 774 patient records reviewed, 545 were included in the study. The average age was 55.4 years. Patients were more likely to receive SUP if they had more risk factors for stress ulcer bleeding (P < 0.001). Overall, 54.9% (299 of 545) of patients received SUP. Of these 299 patients, at least 58.5% did not warrant SUP, depending on the criteria used. Of the entire cohort of 545 non-critically ill patients, 32.1% to 54.9% received unjustified SUP, depending on the criteria applied. There were no cases of stress ulcer bleeding. CONCLUSIONS: Many non-critically ill patients on the teaching service received unjustified SUP, suggesting the need for institutional protocols and educational interventions to promote evidence-based practice during residency training.

Improving the physical diagnosis skills of third-year medical students: a controlled trial of a literature-based curriculum.

OBJECTIVE: To determine if a literature-based physical diagnosis curriculum could improve student knowledge, skill, and self-confidence in physical diagnosis. DESIGN: Prospective controlled trial of an educational intervention. SETTING: Required internal medicine clerkship for third-year medical students at Brown Medical School. PARTICIPANTS: Third-year medical students who completed the internal medicine clerkship during the academic year 1999-2000: 32 students at 1 clerkship site received the intervention; a total of 50 students at 3 other clerkship sites served as controls. INTERVENTION: Physical diagnosis curriculum based on 8 articles from the Journal of the American Medical Association's Rational Clinical Examination series. Intervention students met weekly for 1 hour with a preceptor to review each article, discuss the sensitivity and specificity of the maneuvers and findings, and practice the techniques with an inpatient who agreed to be visited and examined. MEASUREMENTS AND MAIN RESULTS: Physical diagnosis knowledge for the 8 topics was evaluated using a 22-item multiple choice question quiz, skill was evaluated using trained evaluators, and self-confidence was assessed using an end-of-clerkship survey. Intervention students scored significantly higher than the control group on the knowledge quiz (mean correct score 70% vs 63%, P =.002), skills assessment (mean correct score 90% vs 54%, P <.001), and self-confidence score (mean total score 40 vs 35, P =.003), and they expressed greater satisfaction with the physical diagnosis teaching they received in the clerkship. CONCLUSION: This physical diagnosis curriculum was successful in improving students' knowledge, skill, and self-confidence in physical diagnosis.
