Comparing suicide risk screening strategies in Spanish-speaking pediatric patients.

BACKGROUND: Suicide and suicidal behaviors pose significant global public health challenges, especially among young individuals. Effective screening strategies are crucial for addressing this crisis, with depression screening and suicide-specific tools being common approaches. This study compares their effectiveness by evaluating the Ask Suicide-Screening Questions (ASQ) against item 9 of the Patient Health Questionnaire-A (PHQ-A). METHODS: This study is a secondary analysis of the Argentinean-Spanish version of the ASQ validation study, an observational, cross-sectional, and multicenter study conducted in medical settings in Buenos Aires, Argentina. A convenience sample of pediatric outpatients/inpatients aged 10 to 18 years completed the ASQ, PHQ-A, and Suicide Ideation Questionnaire (SIQ) along with clinical and sociodemographic questions. RESULTS: A sample of 267 children and adolescents were included in this secondary analysis. Results show that the ASQ exhibited higher sensitivity (95.1%; 95% CI: 83% - 99%) compared to PHQ-A item 9 (73.1%; 95% CI: 57% - 85%), and superior performance in identifying suicide risk in youth. LIMITATIONS: The study included a convenience sampling and was geographically restricted to Buenos Aires, Argentina. The study also lacked longitudinal follow-up to assess the predictive validity of these screening tools for suicide risk. CONCLUSION: The study highlights the ASQ's effectiveness in identifying suicide risk among youth, emphasizing the importance of specialized screening tools over depression screening tools alone for accurate risk assessment in this population.

Predators control pests and increase yield across crop types and climates: a meta-analysis.

Pesticides have well-documented negative consequences to control crop pests, and natural predators are alternatives and can provide an ecosystem service as biological control agents. However, there remains considerable uncertainty regarding whether such biological control can be a widely applicable solution, especially given ongoing climatic variation and climate change. Here, we performed a meta-analysis focused on field studies with natural predators to explore broadly whether and how predators might control pests and in turn increase yield. We also contrasted across studies pest suppression by a single and multiple predators and how climate influence biological control. Predators reduced pest populations by 73% on average, and increased crop yield by 25% on average. Surprisingly, the impact of predators did not depend on whether there were many or a single predator species. Precipitation seasonality was a key climatic influence on biological control: as seasonality increased, the impact of predators on pest populations increased. Taken together, the positive contribution of predators in controlling pests and increasing yield, and the consistency of such responses in the face of precipitation variability, suggest that biocontrol has the potential to be an important part of pest management and increasing food supplies as the planet precipitation patterns become increasingly variable.

A new species of deep-sea Booralana Bruce, 1986 (Crustacea: Isopoda: Cirolanidae) from The Bahamas, Western North Atlantic.

Booralana nickorum sp. nov. is described from the deep-water slope of the Exuma Sound, The Bahamas, from depths of 540 to 560 metres. It is the fourth species to be assigned to the genus and the second species described from the Western North Atlantic. The species can be distinguished from Booralana tricarinata Camp and Heard, 1988 and the other species by the sub-triangular pleotelson and the uropodal exopod of mature males being far longer than endopod, with both rami extending well beyond the posterior margin of the pleotelson. Additionally, pleopods 3 and 4 lack a prominent angle at midpoint of ramus.

Do Externalizing and Internalizing Symptoms Moderate Medication Response in Preschool Attention-Deficit/Hyperactivity Disorder? A DBPNet Study.

OBJECTIVES: This study aimed to determine whether parent ratings of attention-deficit/hyperactivity disorder (ADHD) symptom severity or externalizing symptoms (EXT) or internalizing symptoms (INT) moderate response to stimulants (STIM) and alpha-2 adrenergic agonists (A2As) in preschool ADHD. METHODS: Health records for children treated with medication for ADHD and with parent rating scale data available (N = 309; age <72 months) were reviewed at 7 Developmental-Behavioral Pediatric Research Network sites. Severity of ADHD was defined as the number of ADHD symptoms occurring often or very often on DSM-IV-based parent rating scales. EXT or INT from standardized rating scales were categorized as T score <60, 60 to <70, or ≥70. Ordinal logistic regression models predicting response to medication were calculated. RESULTS: The median (interquartile range) age at ADHD diagnosis was 59 (54-65) months. One hundred eighty-three participants had ADHD symptom severity, and 195 had EXT or INT data. ADHD severity was not associated with medication response. Both EXT and INT were associated with medication response but with significant medication class by EXT/INT interactions. Children with higher EXT were less likely to respond to STIM, with percentage of nonresponders for T-score categories <60, 60 to <70, and ≥70 being 3.6%, 25.7%, and 33.3% (p = 0.016) and, for A2As, being 60%, 50%, and 33.3% (p = 0.55), respectively. A similar pattern was observed for INT categories: STIM 19.4%, 22.5%, and 50.0% (p = 0.002) and A2As 42.3%, 30%, and 42.3% (p = 0.48), respectively. CONCLUSION: For preschool ADHD, low ratings of EXT or INT are associated with a high likelihood of response to STIM. By contrast, response rates to STIM and A2As are more similar for children with high levels of EXT or INT.

Symmetry in frontal but not motor and somatosensory corticocortical and corticostriatal circuitry.

Neocortex and striatum are topographically organized by cortical areas representing sensory and motor functions, where primary cortical areas are generally used as models for other cortical regions. But different cortical areas are specialized for distinct purposes, with sensory and motor areas lateralized for touch and motor control, respectively. Frontal areas are involved in decision making, where lateralization of function may be less important. This study contrasted the topographic precision of ipsilateral and contralateral projections from cortex based on the injection site location. While sensory cortical areas had strongly topographic outputs to ipsilateral cortex and striatum, they were weaker and not as topographically strong to contralateral targets. Motor cortex had somewhat stronger projections, but still relatively weak contralateral topography. In contrast, frontal cortical areas had high degrees of topographic similarity for both ipsilateral and contralateral projections to cortex and striatum. This contralateral connectivity reflects on the pathways in which corticostriatal computations might integrate input outside closed basal ganglia loops, enabling the two hemispheres to act as a single unit and converge on one result in motor planning and decision making.

Adverse Effects of α-2 Adrenergic Agonists and Stimulants in Preschool-age Attention-deficit/Hyperactivity Disorder: A Developmental-Behavioral Pediatrics Research Network Study.

OBJECTIVES: To characterize and compare the type and frequency of a range of common and uncommon adverse effects (AEs) associated with α-2 adrenergic agonist (A2A) and stimulant treatment of attention-deficit/hyperactivity disorder at preschool-age as well as to evaluate the impact of age on common AEs. STUDY DESIGN: This was a retrospective electronic medical record review of children <72 months of age (n = 497) evaluated at outpatient developmental-behavioral pediatric practices at 7 US academic medical centers within the Developmental-Behavioral Pediatrics Research Network. Data on AEs were abstracted for children who had treatment initiated by a developmental-behavioral pediatrician with an A2A or stimulant medication between January 2013 and July 2017; follow-up was complete by February 2019. RESULTS: A2A and stimulants had distinctive AE profiles. A2A compared with stimulants had a greater proportion with daytime sleepiness and headaches; stimulants had significantly greater proportions for most other AE, including moodiness/irritability, difficulty with sleep, appetite suppression, stomachaches, skin picking/repetitive behaviors, withdrawn behavior, and weight loss. Younger age was associated with disruptive behavior and difficulty with sleep. CONCLUSIONS: Stimulants had a greater rate of most AEs compared with A2A. AE profiles, together with efficacy, should inform clinical decision-making. Prospective randomized clinical trials are needed to fully compare efficacy and AE profiles of A2A and stimulants.

Can Military Role 1 Practitioners Maintain Their Skills Working at Civilian Level 1 Trauma Centers: A Retrospective, Cross-Sectional Study.

BACKGROUND: Introduction: Military Role 1 practitioners have difficulty maintaining skill competency by working solely in military medical treatment facilities. Recognizing this, the Army Medical Department has renewed focus on physician specialty-specific Individual Critical Task Lists (ICTL) and is increasing the number of military-civilian partnerships, wherein small military treatment teams work full-time in civilian trauma centers. Yet, data to validate this approach is lacking. We hypothesize military Role 1 practitioners working full-time at a civilian Level 1 trauma center would attain similar resuscitation-specific procedural frequency to providers deployed to an active combat zone, and use the emergency medicine (EM) ICTL to compare select procedural frequency between a cohort of trauma patients from a civilian Level 1 trauma center and a cohort of combat casualties from the Department of Defense Trauma Registry (DODTR). METHODS: We compared a selected subset of critically-injured, military-aged (18-35 years) trauma patients who were seen in a Level I Trauma Center emergency department (ED) between January 1, 2016 and December 31, 2017 and dispositioned directly either to the operating room, intensive care unit, or morgue to a selected cohort from the Department of Defense Trauma Registry (DODTR) who were seen in EDs in Iraq and Afghanistan between January 2007 and August 2016 using descriptive statistics. The primary outcome was the frequency of ICTL procedures performed, and the secondary outcome was injury severity. RESULTS: We identified 843 civilian patients meeting inclusion criteria, of 1,719 military-aged patients captured by the trauma registry during the study. The selected cohort from the DODTR included 27,359 patients. Demographics were similar between the 2 groups, except the DODTR cohort included significantly more patients with blast trauma (55% versus 0.4%). We found similar ICTL procedural frequency (1 procedure for every 1.84 patients in the civilian cohort compared to one procedure/1.52 patients in the military cohort). CONCLUSION: Role-1 ICTL trauma procedures were performed at similar frequencies between civilian patients seen at a Level 1 trauma center and combat casualties. With proper practice implementation, the opportunity exists for Role 1 practitioners to maintain their trauma resuscitation skills at civilian trauma centers.

Hemodynamic course during ablation and selective hepatic artery embolization for metastatic liver carcinoid: a retrospective observational study.

BACKGROUND: Manipulation of carcinoid tumors during ablation or selective hepatic artery embolization (transarterial embolization, TAE) can release vasoactive mediators inducing hemodynamic instability. The main aim of our study was to review hemodynamics and complications related to minimally invasive treatments of liver carcinoids with TAE or ablation. METHODS: Electronic medical records of all patients with metastatic liver carcinoid undergoing ablation or TAE from 2003 to 2019 were abstracted. Noted were severe hypotension (mean arterial pressure [MAP] ..± 55.ßmmHg), severe hypertension (systolic blood pressure ... 180.ßmmHg), and perioperative complications. Associations of procedure type and pre-procedure octreotide use with intraprocedural hemodynamics were assessed using linear regression. A robust covariance approach using generalized estimating equation method was used to account for multiple observations. RESULTS: A total of 161 patients underwent 98 ablations and 207 TAEs. Severe hypertension was observed in 24 (24.5%) vs. 15 (7.3%), severe hypotension in 56 (57.1%) vs. 6 (2.9%), and cutaneous flushing observed in 2 (2.0%) vs. 48 (23.2%) ablations and TAEs, respectively. After adjusting for preprocedural MAP, ablation was associated with lower intraprocedural MAP compared to TAE (estimate -27.ßmmHg, 95%CI -30 to -24.ßmmHg, p.ß<.ß0.001). Intraprocedural declines in MAP were not affected by preprocedural use of octreotide (p.ß=.ß0.7 for TAE and p.ß=.ß0.4 for ablation). CONCLUSIONS: Ablation of liver carcinoids was associated with substantial hemodynamic instability, especially hypotension. In contrast, a higher number of TAE patients had cutaneous flushing. Preprocedural use of octreotide was not associated with attenuation of intraprocedural hypotension.

Variations in Sexual Behaviors by Use of Specific Substances Among Vancouver Gay, Bisexual, and Other Men Who Have Sex with Men: An Event-Level Analysis.

Event-level studies measure substance use and sexual behaviors happening during a specific sexual encounter, ensuring that both variables are temporally paired. This study explored the event-level associations between a range of sexual behaviors (masturbation, anal sex, oral sex, rimming, fisting, sex toys, and group sex) and five sexualized substances (poppers, methamphetamine, GHB, ecstasy/MDMA, and ketamine) used during 11,582 sexual events reported by 762 gay, bisexual, and other men who have sex with men (GBMSM) in Vancouver, Canada. Data were obtained from a prospective cohort of GBMSM who self-reported their behaviors via computer-based questionnaires on their last sexual encounter with up to five of their most recent partners in the past six months. These clustered data were analyzed with multivariable generalized linear mixed models. Participants reported popper use in 16.1% of sexual encounters, methamphetamine in 8.6%, gamma-hydroxybutyrate (GHB) in 4.1%, ecstasy/3,4-methylenedioxymethamphetamine (MDMA) in 3.3%, and ketamine in 1.5%. Condomless receptive anal sex (25.0% of events) was associated with increased odds of using poppers, methamphetamine, GHB, and ecstasy/MDMA. Group sex (13.1% of events) and sharing sex toys (2.0% of events) were more likely with the use of all five substances. Receiving money/drugs/goods in exchange for sex (2.5% of events) was associated with increased odds of poppers, methamphetamine, GHB, and ecstasy/MDMA use. GBMSM living with HIV (29.9% of participants) had higher odds of using poppers, methamphetamine, and GHB, but lower odds of using ecstasy/MDMA. In conclusion, these event-level results suggest public health strategies are needed to address the possible negative impacts of sexualized substance use among GBMSM.

Revision Surgeries at the Index Level After Cervical Disc Arthroplasty - A Systematic Review.

OBJECTIVE: To perform a systematic literature review on revision surgeries at the index level after cervical disc arthroplasty (CDA) failure. METHODS: A systematic literature review was performed according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. Prospective studies on patients who required a secondary surgery after CDA failure were included for analysis. The minimum follow-up for these studies was 5 years. RESULTS: Out of 864 studies in the original search group, a total of 20 studies were included. From a total of 4,087 patients, 161 patients required a reoperation at the index level. A total of 170 surgeries were performed, as some patients required multiple surgeries. The most common secondary procedures were anterior cervical discectomy and fusion (ACDF) (68%, N = 61) and posterior cervical fusion (15.5%, N = 14), followed by other reoperation (13.3%, N = 12). The associated outcomes for those who required a revision surgery were rarely mentioned in the included literature. CONCLUSION: The long-term revision rate at the index level of failed CDA surgery was 3.9%, with a minimum 5-year follow-up. ACDF was the most commonly performed procedure to salvage a failed CDA. Some patients who required a new surgery after CDA failure may require a more extensive salvage procedure and even subsequent surgeries.

Circumferential Operations of the Cervical Spine.

Generally, a combined anterior and posterior cervical approach is associated with significant morbidity since it requires an extended operative time, greater intraoperative blood loss, and both anterior- and posterior-related surgical complications. However, there are some instances where a circumferential cervical fusion can be advantageous. Our objective is to discuss the indications for circumferential cervical spine procedures. A narrative review of the literature was performed. We include the indications for circumferential cervical approaches of the senior author (KDR). Indications for circumferential approaches include: (1) high-risk patients for pseudoarthrosis, (2) cervical deformity (e.g. , degenerative, posttraumatic, cervicothoracic kyphosis), (3) cervical spine metastases (especially those with multilevel involvement), (4) cervical spine infection, (5) unstable cervical trauma, (6) movement disorders and cerebral palsy, (7) Multiply operated patient (especially postlaminectomy kyphosis and patients with massive ossification of the posterior longitudinal ligament), and when (8) early fusion is desirable. Circumferential procedures may be useful in many different cervical spine conditions requiring surgery. Despite its advantages, particularly with reducing the risk for pseudarthrosis, the benefits of a combined approach must be weighed against the risks associated with a dual approach. With appropriate preoperative planning, intraoperative decision-making, and surgical techniques, excellent clinical outcomes can be achieved.

Deep Neural Networks Can Predict New-Onset Atrial Fibrillation From the 12-Lead ECG and Help Identify Those at Risk of Atrial Fibrillation-Related Stroke.

BACKGROUND: Atrial fibrillation (AF) is associated with substantial morbidity, especially when it goes undetected. If new-onset AF could be predicted, targeted screening could be used to find it early. We hypothesized that a deep neural network could predict new-onset AF from the resting 12-lead ECG and that this prediction may help identify those at risk of AF-related stroke. METHODS: We used 1.6 M resting 12-lead digital ECG traces from 430 000 patients collected from 1984 to 2019. Deep neural networks were trained to predict new-onset AF (within 1 year) in patients without a history of AF. Performance was evaluated using areas under the receiver operating characteristic curve and precision-recall curve. We performed an incidence-free survival analysis for a period of 30 years following the ECG stratified by model predictions. To simulate real-world deployment, we trained a separate model using all ECGs before 2010 and evaluated model performance on a test set of ECGs from 2010 through 2014 that were linked to our stroke registry. We identified the patients at risk for AF-related stroke among those predicted to be high risk for AF by the model at different prediction thresholds. RESULTS: The area under the receiver operating characteristic curve and area under the precision-recall curve were 0.85 and 0.22, respectively, for predicting new-onset AF within 1 year of an ECG. The hazard ratio for the predicted high- versus low-risk groups over a 30-year span was 7.2 (95% CI, 6.9-7.6). In a simulated deployment scenario, the model predicted new-onset AF at 1 year with a sensitivity of 69% and specificity of 81%. The number needed to screen to find 1 new case of AF was 9. This model predicted patients at high risk for new-onset AF in 62% of all patients who experienced an AF-related stroke within 3 years of the index ECG. CONCLUSIONS: Deep learning can predict new-onset AF from the 12-lead ECG in patients with no previous history of AF. This prediction may help identify patients at risk for AF-related strokes.

Use of Telehealth in Fellowship-Affiliated Developmental Behavioral Pediatric Practices During the COVID-19 Pandemic.

OBJECTIVE: This study aims to describe the use of telehealth in developmental behavioral pediatric (DBP) fellowship-affiliated practices during the coronavirus disease 2019 (COVID-19) global pandemic. METHODS: An electronic survey was disseminated to all DBP fellowship-associated practice locations to determine the use of telehealth in DBP care provision, before and since the beginning of the COVID-19 pandemic. We analyzed responses using descriptive statistics. RESULTS: A total of 35 of 42 eligible practice sites responded (83% response rate). Most sites (51.4%) reported using telehealth less than once per month before the COVID-19 pandemic. Since the onset of COVID-19, 100% of programs reported conducting video-based telehealth visits multiple days per week. Most sites reported conducting evaluations and follow-up visits for attention-deficit/hyperactivity disorder, autism spectrum disorder, behavioral concerns, developmental delay, genetic disorders, and learning disability. Most sites were able to continue medication management by telehealth (>88%), offer interpreter services for families with limited English proficiency participating in telehealth visits (>90%), and incorporate trainees and interdisciplinary team members in telehealth visits (>90%). Greater variability was observed in sites' ability to collect telehealth practice evaluation measures. CONCLUSION: Most sites are providing evaluations and ongoing care for DBP conditions through telehealth. The rapid adoption of telehealth can have ramifications for the way that DBP care is delivered in the future; therefore, it is imperative to understand current practice patterns and variations to determine the best use of telehealth.

Osteolysis after cervical disc arthroplasty.

PURPOSE: Cervical disc arthroplasty (CDA) has become an increasingly popular treatment for cervical degenerative disc disease. One potential complication is osteolysis. However, current literature on this topic appears limited. The purpose of this study is to elucidate the incidence, aetiology, consequence, and subsequent treatment of this complication. METHODS: A systematic literature review was performed according to the PRISMA guidelines. Studies discussing the causes, incidence and management of osteolysis after a CA were included. RESULTS: A total of nine studies were included. We divided these studies into two groups: (1) large case series in which an active radiological evaluation for osteolysis was performed (total = six studies), (2) case report studies, which discussed symptomatic cases of osteolysis (total = three). The incidence of asymptomatic osteolysis ranged from 8 to 64%; however, only one study reported an incidence of < 10% and when this case was excluded the incidence ranged from 44 to 64%. Severe asymptomatic bone loss (exposure of the implant) was found in less than 4% of patients. Bone loss from osteolysis appeared to occur early (< 1 year) after surgery and late (> 1 year) as well. Symptomatic patients with osteolysis often required revision surgery. These patients required removal of implant and conversion to fusion in the majority of the cases. CONCLUSIONS: Osteolysis after CDA is common; however, the majority of cases have only mild or asymptomatic presentations that do not require revision surgery. The timing of osteolysis varies significantly. This may be due to differences in the aetiology of osteolysis.

Behavioral Health Screening: Validation of a Strength-Based Approach.

OBJECTIVE: To evaluate the validity of the Behavioral Health Checklist (BHCL) strength-based factor scores and the extent to which this factor has a buffering effect on the relationship between behavioral health symptom severity and children's social problems. METHOD: The parents of 1,392 children aged 4 to 12 completed the BHCL and Child Behavior Checklist (CBCL) during sick and well-child visits to urban and suburban primary care practices affiliated with a large children's hospital. RESULTS: Findings support a single, strength-based factor on the BHCL, and the structure was largely invariant across race, sex, and socioeconomic status. Increased psychopathology symptoms (internalizing, externalizing, and attention-deficit hyperactivity disorder) and lower levels of strengths predicted increased social problems (p < 0.001). Moreover, the interaction terms were statistically significant in all analyses, suggesting that higher levels of strengths may buffer the deleterious impact of psychopathology symptoms on social problems. Post hoc analyses indicated that the buffering influence of strengths on the relationship between psychopathology symptoms and social problems was clinically meaningful except in the older sample for the relationship between externalizing and social problems. CONCLUSION: The findings support the validity of a strength-based factor of the BHCL and indicate that this factor has a buffering effect on the association between the degree of child mental health symptoms and level of social impairment. This factor, in combination with the problem-focused factors of the BHCL, provides a balanced approach to screening children's mental health functioning.

Chronic Care for Attention-Deficit/Hyperactivity Disorder: Clinical Management from Childhood Through Adolescence.

OBJECTIVE: Impairments generally persist when children diagnosed with attention-deficit/hyperactivity disorder (ADHD) mature into adolescence. To examine changes in ADHD care during the transition from childhood to adolescence, we conducted a retrospective, longitudinal cohort study of patients diagnosed with ADHD before the age of 10 years to assess changes from preadolescence through adolescence in (1) frequency by which primary care providers offer ADHD care to patients, (2) range of concerns assessed during patient encounters, and (3) treatments implemented or recommended. METHODS: We identified patients from 3 practices included in a large primary care network who (1) were born between 1996 and 1997, (2) were diagnosed with ADHD before the age of 10 years, and (3) received primary care continuously from age 9 through late adolescence. Clinical care was compared among patients in preadolescence (age 9-11), early adolescence (age 12-14), and late adolescence (age 15-18). RESULTS: Children diagnosed with ADHD before the age of 10 years were less likely to have a documented visit for ADHD during late adolescence (41% of patients) compared with preadolescence (63%, p < 0.001). Evidence of monitoring for depression, suicide, and substance abuse increased from preadolescence to adolescence (p < 0.001) and occurred in about 90% of adolescent patients. However, monitoring for risky sexual activity occurred in only about 50% of adolescents. Discussions of medication diversion and driver readiness were essentially not documented. CONCLUSION: The findings raise concerns about how primary care providers manage adolescents with a history of ADHD. Improving monitoring of risky sexual behavior and driver readiness and providing patient education about medication diversion are needed.

Warm temperatures, cool sponges: the effect of increased temperatures on the Antarctic sponge Isodictya sp.

Although the cellular and molecular responses to exposure to relatively high temperatures (acute thermal stress or heat shock) have been studied previously, only sparse empirical evidence of how it affects cold-water species is available. As climate change becomes more pronounced in areas such as the Western Antarctic Peninsula, both long-term and occasional acute temperature rises will impact species found there, and it has become crucial to understand the capacity of these species to respond to such thermal stress. Here, we use the Antarctic sponge Isodictya sp. to investigate how sessile organisms (particularly Porifera) can adjust to acute short-term heat stress, by exposing this species to 3 and 5 °C for 4 h, corresponding to predicted temperatures under high-end 2080 IPCC-SRES scenarios. Assembling a de novo reference transcriptome (90,188 contigs, >93.7% metazoan BUSCO genes) we have begun to discern the molecular response employed by Isodictya to adjust to heat exposure. Our initial analyses suggest that TGF-ß, ubiquitin and hedgehog cascades are involved, alongside other genes. However, the degree and type of response changed little from 3 to 5 °C in the time frame examined, suggesting that even moderate rises in temperature could cause stress at the limits of this organism's capacity. Given the importance of sponges to Antarctic ecosystems, our findings are vital for discerning the consequences of short-term increases in Antarctic ocean temperature on these and other species.
