Secondary Bony Defects after Soft Tissue Reconstruction in Limb-Threatening Lower Extremity Injuries: Does the Approach to Flap Elevation Matter?

BACKGROUND: Limb-threatening lower extremity injuries often require secondary bone grafting after soft tissue reconstruction. We hypothesized that there would be fewer wound complications when performing secondary bone grafting via a remote surgical approach rather than direct flap elevation. METHODS: A retrospective cohort study was performed at a single Level 1 trauma center comparing complications after secondary bone grafting in patients who had undergone previous soft tissue reconstruction after open tibia fractures between 2006 and 2020. Comparing bone grafting via a remote surgical incision versus direct flap elevation, we evaluated wound dehiscence requiring return to the operating room as the primary outcome. Secondary outcomes were deep infection and delayed amputation. RESULTS: We identified 129 patients (mean age: 40 years, 82% male) with 159 secondary bone grafting procedures. Secondary bone grafting was performed via a remote surgical approach in 54% (n = 86) and direct flap elevation in 46% (n = 73) of cases. Wound dehiscence requiring return to the operating room occurred in one patient in the flap elevation group (1%) and none of the patients in the remote surgical approach. The odds of deep wound infection (OR, 1.77; p = 0.31) or amputation (OR, 1.43; p = 0.73) did not significantly differ between surgical approaches. No significant differences were found in complications between the reconstructive surgeon elevating and re-insetting the flap and the orthopaedic trauma surgeon performing the flap elevation and re-inset. CONCLUSION: Direct flap elevation for secondary bone grafting after soft tissue reconstruction for open tibia fractures did not result in more complications than bone grafting via a remote surgical approach. These findings should reassure surgeons to allow other clinical factors to influence the surgical approach for bone grafting.

What Outcomes Are Most Important to Patients Following a Lower Extremity Limb-threatening Injury?

OBJECTIVE: To determine what outcomes are most important to patients after a limb-threatening injury, and if those preferences vary based on the patients' treatment (salvage vs amputation), health, demographics, or time since injury. BACKGROUND: The preferences that motivate the patients' choice of treatment following a limb-threatening injury are poorly understood. Discrete choice experiments (DCEs) are a robust survey methodology to quantify preferences. METHODS: Patients with a history of traumatic limb-threatening injury, January 2010 to December 2020, completed a survey with our DCE and the Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaire. The DCE attributes included recovery time, function, appearance, cost, and time in hospital. We used conditional logit modeling to estimate the relative importance of each attribute on a scale of 0% to 100%, determine willingness to pay for improvements in the included attributes, and assess variation in preferences based on patient characteristics, including PROMIS score. RESULTS: A total of 150 patients completed the survey (104 limb salvage, 46 amputation; mean age, 48±16 years; 79% male). Regaining preinjury function [relative importance=41%; 95% confidence interval (CI), 37%-45%] and minimizing costs (24%; 95% CI, 21%-28%) were of greatest importance. Changes in appearance were least important (7%; 95% CI, 5%-9%). The hierarchy of preferences did not vary between those who had limb salvage or amputation, but patient age, physical and mental health, and income were associated with preference variation. CONCLUSIONS: Patients with limb-threatening injuries most valued gains in function and reduced out-of-pocket costs.

A preliminary prospective study of health-related quality of life among Chinese-American breast cancer survivors.

PURPOSE: This study examined the predictors of health-related quality of life (HRQOL) and changes in HRQOL over a 1-year period among Chinese-American breast cancer survivors (BCS). METHODS: A two-wave longitudinal research design included participants from hospital-based cancer registries and community organizations in Los Angeles. Participants completed mailed questionnaires at baseline and 12-month follow-up. HRQOL was measured using the Functional Assessment of Cancer Therapy-General (FACT-G v.4). Change in HRQOL was assessed using a 7-point meaningful change score. RESULTS: Participants were 73 Chinese-American BCS, a majority of whom were middle-aged (M = 54.6, SD = 9.2), lower income (63% < 45K), and diagnosed with stage I-II (83%) breast cancer. Regression analyses showed that multilevel contextual factors including general health perception, quality of care, life stress, and improvement in general health perception significantly predicted HRQOL at baseline and follow-up. The final model explained 72% of the variance of HRQOL. The examination of meaningful change indicated that improvement was reported by 32% (n = 22) and deterioration by 25% (n = 17); the majority indicated minimal change (43%, n = 30). Improvement was associated with increases in family communication, social support, and general health perception, while deterioration was associated with declines in social support, family communication, and general health perception. CONCLUSION: Findings indicate that among Chinese-American BCS, HRQOL is influenced by socioecological factors such as family communication and life stress. Results suggest that cancer survivorship outcomes research may benefit from theoretical foundations that examine the broader contextual dimensions that seem to impact and predict HRQOL. Implications for research are discussed.

Rational Ligand Design Enables pH Control over Aqueous Iron Magnetostructural Dynamics and Relaxometric Properties.

Complexes of Fe3+ engage in rich aqueous solution speciation chemistry in which discrete molecules can react with solvent water to form multinuclear µ-oxo and µ-hydroxide bridged species. Here we demonstrate how pH- and concentration-dependent equilibration between monomeric and µ-oxo-bridged dimeric Fe3+ complexes can be controlled through judicious ligand design. We purposed this chemistry to develop a first-in-class Fe3+-based MR imaging probe, Fe-PyCy2AI, that undergoes relaxivity change via pH-mediated control of monomer vs dimer speciation. The monomeric complex exists in a S = 5/2 configuration capable of inducing efficient T1-relaxation, whereas the antiferromagnetically coupled dimeric complex is a much weaker relaxation agent. The mechanisms underpinning the pH dependence on relaxivity were interrogated by using a combination of pH potentiometry, 1H and 17O relaxometry, electronic absorption spectroscopy, bulk magnetic susceptibility, electron paramagnetic resonance spectroscopy, and X-ray crystallography measurements. Taken together, the data demonstrate that PyCy2AI forms a ternary complex with high-spin Fe3+ and a rapidly exchanging water coligand, [Fe(PyCy2AI)(H2O)]+ (ML), which can deprotonate to form the high-spin complex [Fe(PyCy2AI)(OH)] (ML(OH)). Under titration conditions of 7 mM Fe complex, water coligand deprotonation occurs with an apparent pKa 6.46. Complex ML(OH) dimerizes to form the antiferromagnetically coupled dimeric complex [(Fe(PyCy2AI))2O] ((ML)2O) with an association constant (Ka) of 5.3 ± 2.2 mM-1. The relaxivity of the monomeric complexes are between 7- and 18-fold greater than the antiferromagnetically coupled dimer at applied field strengths ranging between 1.4 and 11.7 T. ML(OH) and (ML)2O interconvert rapidly within the pH 6.0-7.4 range that is relevant to human pathophysiology, resulting in substantial observed relaxivity change. Controlling Fe3+ µ-oxo bridging interactions through rational ligand design and in response to local chemical environment offers a robust mechanism for biochemically responsive MR signal modulation.

Return to work after robot-assisted laparoscopic prostatectomy versus radical retro-pubic prostatectomy.

INTRODUCTION: We compared the return-to-work interval (RTWI) after radical retro-pubic prostatectomy (RRP) and robot-assisted laparoscopic prostatectomy (RALP) in men being treated for early-stage prostate cancer. MATERIALS AND METHODS: We mailed a 28-item questionnaire to a random sample of 2,696 patients who either had RRP from 1995 to 2004 or RALP from 2004 to 2011. RESULTS: We received analyzable questionnaires from 315 patients; 178 had RALP and 137 had RPP. The median RTWI was shorter in the RALP group than in the RRP group (3 versus 4 weeks, p = .016). The percent of subjects who had not returned to work 4 weeks after surgery was 23.6% for RALP and 38.2% for RRP (p = .010). In multivariate regression analysis, surgical approach was a significant predictor of RTWI independent of other social/clinical variables that were associated with either surgical approach or RTWI (p = .014). CONCLUSION: Our data support a shortening of RTWI by RALP.

Assessing Attentional Bias in Secondary Cleft Lip Deformities: An Eye-Tracking Study.

OBJECTIVE: Using a well-established measure of attention, we aimed to objectively identify differences in severity between types of simulated secondary cleft lip deformities. DESIGN: Volunteer participants viewed a series of images of a child digitally modified to simulate different secondary unilateral cleft lip deformities (long lip, short lip, white roll/vermilion disjunction, and vermilion excess), a lip scar with no secondary deformity, or a normal lip. Eye movements were recorded using a table-mounted eye-tracking device. Dwell times for 7 facial regions (eyes, nose, mouth, left ear, right ear, scar, and entire face) were compared. PARTICIPANTS: Forty-six naive adults (25 male; mean age 25.5 years) were recruited from our local university community. MAIN OUTCOME: The primary outcome of the study was cumulative dwell time between facial regions (eyes, nose, mouth, left ear, right ear, scar, and entire face). RESULTS: Participants spent significantly more time focused on the upper lip regions in patients with simulated secondary deformities relative to those who did not ( P < .01). Severe short lip deformities resulted in longer fixation times than severe long lips ( P < .05). Participants spent less time focused on the eye region in the presence of a secondary lip deformity ( P < .05). When total facial fixation time was assessed, short lip deformities resulted in the greatest duration dwell time ( P < .001). CONCLUSIONS: This study presents objective data to support the concept that observers show varying degrees of attentional bias to the lip region depending on the type and severity of the simulated secondary cleft lip deformity.

Repair of Primary Cleft Palate and Oronasal Fistula With Acellular Dermal Matrix: A Systematic Review and Surgeon Survey.

OBJECTIVE: The current review and survey aim to assess the effectiveness of acellular dermal matrix (ADM) in the repair of cleft palate and oronasal fistula and to evaluate the current trends of ADM use in palate surgery. DESIGN: A systematic review of English articles was conducted using MEDLINE (1960 to July 1, 2016), the Cochrane Controlled Trials Register (1960 to July 1, 2016), and EMBASE (1991 to July 1, 2016). Additional studies were identified through a review of references cited in initially identified articles. Search terms included "cleft palate," "palatal," "oronasal fistula," "acellular dermal matrix," and "Alloderm®." An online survey was disseminated to members of the American Cleft Palate-Craniofacial Association to assess current trends in ADM use in palate surgery. STUDY SELECTION: All studies evaluating the outcome of primary palate repair or repair of oronasal fistula with the use of aceullar dermal matrix products were included in the review. RESULTS: Twelve studies met inclusion criteria for review. Studies were generally of low quality, as indicated by methodological index for non-randomized studies (MINORS) scores ranging from 7 to 14. The pooled estimate for fistula formation after primary palatoplasty following ADM use was 7.1%. The pooled estimate for recurrence of fistula after attempted repair using ADM was 11%. Thirty-six cleft surgeons responded to the online survey study. Of these, 45% used ADM in primary cleft palate repair, while 67% used ADM for repair of oronasal fistulae. CONCLUSION: Use of ADM products is commonplace in palate surgery. Despite this, there is a paucity of high-quality data demonstrating benefit. Further randomized controlled trials examining ADM in palate surgery are required to help develop structured guidelines and improve care.

Pressure ulcer prevalence and perceptions on prevention: a hospital-wide survey of health professionals.

OBJECTIVE: Hospital-acquired pressure ulcers (HAPUs) remain a problem despite numerous prevention initiatives. To understand why, it is necessary to know health professionals' perceptions regarding the importance of prevention, and the usability of current initiatives. We hypothesised that positive perceptions of existing initiatives would not be correlated with low HAPU prevalence, and that health professionals would perceive the initiatives to have a low usability. METHOD: A two-part, online survey was developed and distributed electronically to nurses, in-training physicians and attending physicians, across all inpatient and perioperative departments of an academic hospital. Part one of the survey was the Agency for Healthcare Research and Quality (AHRQ) Staff Attitude Scale on beliefs regarding PU prevention; part two was additional questions on the usability of existing preventative initiatives. The results of the survey were compared with quarterly HAPU prevalence data by hospital unit. RESULTS: In total, 839 health professionals completed the survey (579 nurses, 131 residents, 119 attending physicians). The mean score for the AHRQ survey was 42.5 (≥40 denoting positive perceptions). There was a moderate correlation between AHRQ scores and prevalence of HAPUs (r=-0.60, p=0.402). For usability, repositioning was felt to be the most effective intervention (mean: 4.54, standard deviation (SD): 0.64), while educational posters were felt to be the least effective (mean: 3.31, SD: 0.99). Respondents generally rated satisfaction much lower, with no single initiative significantly better than the others (range: 3.21-3.79). Perceived effectiveness and satisfaction were all positively correlated. CONCLUSION: High HAPU prevalence, despite position perceptions, suggests that prevention methods are not as effective as thought, or they are not being used as widely as they should. Further research should take advantage of positive attitudes by prospectively investigating the usability of novel interventions.

PHIRST Trial - pharmacist consults: prioritization of HIV-patients with a referral screening tool.

The role of pharmacists in HIV outpatient clinics has greatly increased in the past decades. Given the limited resources of the health system, the prioritization of pharmacist consults is now a main concern. This study aimed to create a scoring system allowing for standardized prioritization of pharmacist consults for patients living with HIV. Data was retrospectively collected from 200 HIV patients attending the Chronic Viral Illness Service at the McGill University Health Center. An expert panel consisting of four pharmacists working in the field of HIV prioritized each patient individually, after which a consensus was established and was considered as the gold standard. In order to create a scoring system, two different methods (Delphi, statistical) were used to assign a weight to each characteristic considered to be important in patient prioritization. A third method (equal weight to each characteristic) was also evaluated. The total score per patient for each method was then compared to the expert consensus in order to establish the score cut-offs to indicate the appropriate categories of delay in which to see the patient. All three systems failed to accurately prioritize patients into urgency categories ("less than 48 h", "less than 1 month", "less than 3 months", "no consult required") according to expert pharmacist consensus. The presence of high level interactions between patient characteristics, the limited number of patients and the low prevalence of some characteristics were hypothesized as the main causes for the results. Creating a prioritization tool for pharmacy consults in HIV outpatient clinics is a complex task and developing a decision tree algorithm may be a more appropriate approach in the future to take into account the importance of combinations of patient characteristic.

Surgical Correction of Nonsyndromic Sagittal Craniosynostosis: Concepts and Controversies.

Sagittal craniosynostosis remains the most common type of isolated craniosynostosis, accounting for nearly half of all nonsyndromic cases. The clinical diagnosis is typically made on the basis of a scaphocephalic head shape and is confirmed by computed tomography or magnetic resonance imaging. The current review examines the major surgical options for correction of isolated sagittal craniosynostosis, including their complications and short- and long-term outcomes. Reconstructive techniques have benefited from advances in perioperative anesthesia monitoring and improved safety of blood transfusion. Although extensive calvarial remodeling is considered safe and may confer greater long-term skull shape correction and decreased neuropsychological sequelae, minimally invasive techniques, such as device-assisted expansion of the cranium continue to increase in popularity. This review underscores the need for additional prospective studies comparing different techniques to determine the optimal reconstructive approach for correction of sagittal craniosynostosis.

The optimal orthosis and motion protocol for extensor tendon injury in zones IV-VIII: A systematic review.

STUDY DESIGN: Systematic review INTRODUCTION: There exist numerous combinations of orthoses and motion protocols for the treatment of proximal extensor tendon injuries. PURPOSE: The purpose of this study was to determine the optimal combination of motion protocol and orthotic treatment for the rehabilitation of proximal extensor tendon injuries (zones IV-VIII). METHODS: A systematic review of English language randomized clinical trials and cohort studies investigating extensor tendon rehabilitation from 1960 to 2016 was conducted in MEDLINE, Embase, Cochrane, CINAHL, PEDro, and OTseeker. Outcomes of total active motion, grip strength, return to work, patient attrition, and patient-reported outcomes were compared. RESULTS: Eleven studies of predominantly average quality (1, low; 8, average; and 2, high) were included in the final review. Results were difficult to compare due to differences in reporting. Early total active motion and final grip strength were greater with dynamic extension orthoses (191°-214°; 35-38 kg/89% contralateral side) and relative motion orthoses (205°-236°; 85%-95% contralateral side) compared to static orthoses (79°-202°; 23-34 kg/59% contralateral side). Four studies excluded patients who did not follow up, and loss to follow-up was 12%-33% in the other studies. Patient-reported outcomes were not comparable, as they were only included in 3 studies, and each used a different assessment tool. CONCLUSION: Average quality evidence supports the use of early active motion (EAM) as the superior motion protocol, but optimal orthosis to deliver EAM could not be determined. Prospective research should focus on patient-reported outcomes and the design of orthoses that facilitate the use of the EAM. LEVEL OF EVIDENCE: 2a.

Efficacy of Monitoring Devices in Support of Prevention of Pressure Injuries: Systematic Review and Meta-analysis.

GENERAL PURPOSE: To present a systematic review of the literature assessing the efficacy of monitoring devices for reducing the risk of developing pressure injuries. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant should be better able to:1. Explain the methodology of the literature review and its results.2. Discuss the scope of the problem and the implications of the research. ABSTRACT: OBJECTIVE: To assess the efficacy of monitoring devices for reducing the risk of developing pressure injuries (PIs). DATA SOURCES: The authors systematically reviewed the literature by searching PubMed/MEDLINE and CINAHL databases through January 2016. STUDY SELECTION: Articles included clinical trials and cohort studies that tested monitoring devices, evaluating PI risk factors on patients in acute and skilled nursing settings. The articles were scored using the Methodological Index for Non-randomized Studies. DATA EXTRACTION: Using a standardized extraction form, the authors extracted patient inclusion/exclusion criteria, care setting, key baseline, description of monitoring device and methodology, number of patients included in each group, description of any standard of care, follow-up period, and outcomes. DATA SYNTHESIS: Of the identified 1866 publications, 9 met the inclusion criteria. The high-quality studies averaged Methodological Index for Non-randomized Studies scores of 19.4 for clinical trials and 12.2 for observational studies. These studies evaluated monitoring devices that measured interface pressure, subdermal tissue stress, motion, and moisture. Most studies found a statistically significant decrease in PIs; 2 studies were eligible for meta-analysis, demonstrating that use of monitoring devices was associated with an 88% reduction in the risk of developing PIs (Mantel-Haenszel risk ratio, 0.12; 95% confidence interval, 0.04-0.41; I = 0%). CONCLUSIONS: Pressure injury monitoring devices are associated with a strong reduction in the risk of developing PIs. These devices provide clinicians and patients with critical information to implement prevention guidelines. Randomized controlled trials would help assess which technologies are most effective at reducing the risk of developing PIs.

Social support sources, types, and generativity: a focus group study of cancer survivors and their caregivers.

Various research studies have identified the sources and types of support that people with cancer receive; however, few have focused on identifying the specific characteristics of emotional, instrumental, and informational support. In this study, focus groups consisting of Gilda's Club members explored the types of support that people with cancer and their caregivers experienced and valued. Results showed that although men and women with cancer and caregivers identify similar sources of support, they experience different types of support. Results also indicated a desire among participants to help and support others, a concept referred to as generativity. Implications for social workers and health care providers are explored.

Self-induced Hot Water Finger Burn Trying to Get Feeling Back after Ropivacaine Block.

This case report is about a patient with self-induced hot water burns several hours after an infraclavicular block with ropivacaine for a scaphoid fracture operation. This patient was honest about what happened. However, some patients are too embarrassed to admit what they did to themselves. The injury may be misdiagnosed by the emergency department physician or by the surgeon because the history is incomplete. The resulting burn, which can lead to fingertip loss when severe, can be erroneously misdiagnosed as an ischemic injury after lidocaine with epinephrine local anesthesia. Most hand surgeons have seen ischemic finger injuries the morning after failed finger replantation. Acutely ischemic fingers from arterial insufficiency do not have parallel hot water burn lines, reactive hyperemia at the base of the burn, or burn blisters at the fingertips. The purpose of this article and its video is to help physicians and nurses recognize the three signs of self-induced hot water finger burns after local anesthesia: (1) a parallel hot water line in the fingers at the proximal burn level; (2) reactive hyperemia just proximal to the burn line; (3) burn blisters in the submerged fingertips. When seeing postoperative patients with these signs, the examining clinician may tactfully ask: "Did you try to get the feeling back in your fingers by warming them?" It is hoped that the patient may then reveal that he tried warming the finger in water, and that may lead to the truth that the water was indeed too hot.

Medication Error Minimization Scheme (MEMS) in an adult tertiary intensive care unit (ICU) 2009-2011.

INTRODUCTION: The Medication Error Minimisation Scheme (MEMS) is a locally based ongoing multidisciplinary, multifaceted quality improvement (QI) project within an Australian adult tertiary level Intensive Care Unit (ICU). The project commenced in 2009. Its primary aim is to enhance medication safety within this ICU by utilising existing resources. The aim of this paper is to provide a descriptive account of the various activities, interventions and results of this project within the first three years. METHODS: The research design for this project was based upon Plan-Do-Study-Act (PDSA) cycles associated with QI projects. Medication error rates and audits of: intravenous infusions, incompatible intravenous medications and incorrect documentation of withheld medications were analyzed according to simple statistical techniques. Initial and follow up medication safety surveys were compared using basic statistical analysis. Focus groups exploring barriers and enablers of medication incident reporting were analyzed according to qualitative techniques associated with focus group discussions. Other interventions included: regular education sessions; discussions within other departmental meetings such as nursing staff meetings and Morbidity and Mortality meetings; and bedside discussions and demonstrations. Promotion of medication safety occurred within a number of forums; activities and findings were advertised and displayed; a recognizable Logo for MEMS was employed; and incentives were provided for staff. RESULTS: Reported Medication Incidents (MIs) increased from 6.2 to 14.9 MIs per 1000 patient days. Audits and chart reviews confirmed that more MIs are uncovered by employing a variety of techniques in addition to incident reporting. Staff surveys provided a rich source of information regarding medication safety. Audits of intravenous infusions revealed a reduced error rate from 38/331 (11.5%) to 15/468 (3.2%). Chart review of incorrect documentation of omitted medications decreased from 105/347 (30.3%) to 104/486 (21.4%). Focus groups provided information that was able to be used in a number of hospital forums in order to explain the impact of existing systems upon ICU staff. CONCLUSION: This ongoing QI project was able to achieve its targeted goals. The MI reporting rate was increased. This project demonstrated that measurable, "non-incident report" errors can be reduced by focusing upon and promoting medication safety in the ICU. These activities demonstrated a workplace that values medication safety, the discovery of shortfalls and the benefits of ongoing improvement.

Presentation and aetiology of paediatric trigger finger: a systematic review.

Paediatric trigger finger is a rare condition distinct from paediatric trigger thumb and adult trigger digits. We performed a systematic review of paediatric trigger finger presentation and aetiology in order to guide workup and management. Fifty-one studies with 193 patients and 398 trigger fingers were included. Most patients had a single, unilateral trigger finger (54%). Fifty-five patients (29%) had an underlying condition, such as mucopolysaccharidosis; these cases appeared to be associated with multiple or bilateral trigger fingers or with carpal tunnel syndrome. All patients with mucopolysaccharidosis were treated surgically. Conservative management was reported in 33% of all patients, and two-thirds of these did not need further intervention. Patients undergoing surgical release infrequently had recurrence of triggering (6%). We propose an algorithmic approach for patients presenting with paediatric trigger finger. Presence of bilateral or multiple trigger digits or concomitant carpal tunnel syndrome should raise suspicion for an atypical underlying pathology.

Lack of Vesicular Zinc Does Not Affect the Behavioral Phenotype of Polyinosinic:Polycytidylic Acid-Induced Maternal Immune Activation Mice.

Zinc is important in neural and synaptic development and neuronal transmission. Within the brain, zinc transporter 3 (ZnT3) is essential for zinc uptake into vesicles. Loss of vesicular zinc has been shown to produce neurodevelopmental disorder (NDD)-like behavior, such as decreased social interaction and increased anxiety- and repetitive-like behavior. Maternal immune activation (MIA) has been identified as an environmental factor for NDDs, such as autism spectrum disorders (ASDs) and schizophrenia (SZ), in offspring, which occurs during pregnancy when the mother's immune system reacts to the exposure to viruses or infectious diseases. In this study, we investigated the interaction effect of a genetic factor [ZnT3 knockout (KO) mice] and an environmental factor (MIA). We induced MIA in pregnant female (dams) mice during mid-gestation, using polyinosinic:polycytidylic acid (polyI:C), which mimics a viral infection. Male and female ZnT3 KO and wild-type (WT) offspring were tested in five behavioral paradigms: Ultrasonic Vocalizations (USVs) at postnatal day 9 (P9), Open Field Test, Marble Burying Test, three-Chamber Social Test, and Pre-pulse Inhibition (PPI) in adulthood (P60-75). Our results indicate that loss of vesicular zinc does not result in enhanced ASD- and SZ-like phenotype compared to WT, nor does it show a more pronounced phenotype in male ZnT3 KO compared to female ZnT3 KO. Finally, MIA offspring demonstrated an ASD- and SZ-like phenotype only in specific behavioral tests: increased calls emitted in USVs and fewer marbles buried. Our results suggest that there is no interaction between the loss of vesicular zinc and MIA induction in the susceptibility to developing an ASD- and SZ-like phenotype.

Association of Radial Head Fracture Treatment With Long-Term Function.

BACKGROUND: Radial head fractures are often associated with poor outcomes. Both open reduction and internal fixation (ORIF) and radial head arthroplasty (RHA) might be considered in operative cases. This study aimed to compare long-term patient-reported functional outcomes among patients with operatively treated radial head fractures. METHODS: A cross sectional study conducted at a Level I trauma center was used to identify patients with a radial head fracture who underwent ORIF or RHA between 2006 and 2018, and agreed to complete a survey in 2020. The primary outcome measure was the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score. RESULTS: Seventy-six patients participated in the study. No significant differences in outcomes were observed between groups. QuickDASH scores were similar for both groups (ORIF: mean = 15.7, SD = 18.4; RHA: mean = 22.8, SD = 18.6; mean difference = 0.2 [-9.0 to 9.3], P = .97). Nineteen (37%) ORIF patients and 12 (48%) RHA patients reported a need for pain medication (adjusted odds ratio [OR] = 0.8 [0.3-2.4], P = .70). Thirteen (25%) ORIF patients and 6 (24%) RHA patients required additional surgery (adjusted OR = 1.7 [0.5-6.2], P = .39). A subgroup analysis of multi-fragmentary fractures revealed similar findings. CONCLUSION: Patient-reported outcomes, which included a subgroup analysis of multi-fragmentary fractures, were similar between ORIF and RHA groups at an average of 7.5 years from surgery. Reconstructing the radial head might not result in worse outcomes than RHA when both options are employed according to the best judgment of the operating surgeon.

Couple and family interventions for high mortality health conditions: A strategic review (2010-2019).

The earliest publications in the field of marriage and family therapy introduced interventions conducted with families experiencing complex health conditions. This strategic review captures an evaluation of efficacy for 87 couple and family interventions published between 2010 and 2019 with a focus on the leading causes of mortality in the United States. These health conditions include chromosomal anomalies and accidents with infants aged 0-4 years; accidents and cancer among children aged 5-14; accidents among adolescents aged 15-24; and heart disease, cancer, accidents, chronic lower respiratory diseases, stroke, Alzheimer's disease, diabetes, influenza/pneumonia, and nephritis/nephrosis among adults 25 and older. Results support the need for greater inclusion of couples and families in assessments and interventions. The greatest chasm in efficacy research was with minoritized couples and families. Implications include ways to initiate couple and family interventions in the context of health conditions with attention given to accessibility, recruitment, retention, and evaluation.

The Effect of Padded Adhesive Dressing and Static Body Position on Sacral Interface Pressure.

OBJECTIVES: Padded adhesive bandages are frequently used in the inpatient setting for sacral pressure injury prevention, but it is unclear whether they truly decrease interface pressure. We hypothesized such devices reduce sacral peak interface pressure in the supine position, which would be further reduced in 30-degree reclined and upright seated positions. METHODS: Study participants rested with their sacrum on a pressure-sensing mat, in 3 positions, for 30 seconds each: (1) sitting upright; (2) supine; and (3) supine against 30-degree wedge. Measurements were made with and without a padded adhesive bandage overlying the sacrum. Age, sex, and body mass index (BMI) were collected. These variables were entered sequentially, in an a priori order to construct a linear mixed-effects model. RESULTS: Forty healthy adults participated. After controlling for by-subject variation, age, and sex, BMI did not influence peak sacral pressure (P = 0.22), although the effect of body position was significant (P < 0.01). Subsequent addition of padded adhesive dressing was nonsignificant (P = 0.17); sacral peak pressure was similar with a padded adhesive dressing (247.8 ± 147.3 mm Hg) or without (mean ± standard deviation = 229.8 ± 127.7 mm Hg). Lastly, there was no significant interaction between BMI and body position (P = 0.11). CONCLUSIONS: Padded adhesive bandages did not reduce interface pressure in any position. Sacral pressure was highest in the supine position and was not specifically affected by BMI. If padded bandages provide clinically significant reduction in pressure injury incidence, it is not simply through the reduction of interface pressure.
