Risk factors for surgical site infection after surgical treatment of closed distal radial fractures.

We assessed operatively treated closed distal radial fractures to identify independent risk factors for surgical site infection after treatment. A retrospective review was carried out of 531 operatively treated closed distal radial fractures over a 5-year period. Multiple logistic regression was performed with infection as the dependent variable, using a stepwise regression procedure to select variables to construct the final model. In total, 19 (3.6%) fractures were complicated by postoperative surgical site infection. Uncontrolled diabetes with HbA1c >7, the presence of external fixation or external Kirschner wires, and tobacco use were significant independent predictors of infection. Age and time in the operating room were also statistically significant predictors but deemed to be not clinically meaningful.Level of evidence: IV.

Carpal dislocations.

Carpal dislocations result from sequential disruption of the complex relationship between the bones and ligaments of the wrist. Injuries to the carpus occur via predictable mechanisms, an understanding of which is critical to identify and treat these frequently missed patterns of injury and to avoid the sequela of chronic instability. Lunate dislocations are by far the most common, but isolated dislocation of other carpal bones can also occur. Open reduction and internal fixation still remains the gold standard for treatment regardless of the debate around the specific approaches. These high-energy injuries are associated with significant long-term morbidity even when identified promptly and appropriately treated. This review will focus on the evaluation and management of common forms of carpal dislocations.

Evaluation of Radiographic Parameters Following Dorsal Wrist-Spanning Plate Fixation of Distal Radius Fractures to the Second Versus Third Metacarpal.

PURPOSE: Dorsal wrist-spanning plate fixation for comminuted, intra-articular distal radius fractures involves the indirect reduction of intra-articular fractures via ligamentotaxis. The reduction is maintained by application of a bridge plate from the radial diaphysis to either the second or third metacarpal. The objective of this study was to retrospectively compare radiographic outcomes between distal radius fractures managed with bridge plate fixation to the second versus third metacarpal. METHODS: A single-institution retrospective review identified 50 cases of distal radius fractures that underwent dorsal wrist-spanning plate fixation, with 9 and 41 fractures undergoing fixation to the second and third metacarpals, respectively. Radiographic parameters, such as radial height, radial inclination, volar tilt, and ulnar variance, were measured at 3 time points: immediately after surgery, immediately prior to elective plate removal, and at the final follow-up. Radiographic measurements of the 2 cohorts were compared at the 3 time points. RESULTS: Final radiographs showed an average radial height of 8.9 mm versus 9.4 mm for the second versus third metacarpal cohorts, respectively; average radial inclination of 17.4° for both the second and third metacarpal cohorts; average volar tilt of 1.9° versus 1.7° for the second versus third metacarpal cohorts, respectively; and an average ulnar variance of +0.6 mm versus +0.1 mm for the second versus third metacarpal cohorts, respectively. Radiographic parameters of the second and third metacarpal cohorts were similar across all the time points. Additionally, evaluation of the radiographic parameters across the 3 time points (immediately after surgery, immediately prior to elective plate removal, and at the final follow-up) demonstrated little to no loss of radiographic alignment. CONCLUSIONS: Radiographic outcomes for distal radius fractures managed with bridge plate fixation to the second versus third metacarpal appear similar. The distal plate fixation site can likely be determined on the basis of fracture anatomy and patient-specific features. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Risk Factors and Reasons for Emergency Department Visits Within 30 Days of Elective Hand Surgery: An Analysis of 3,261 Patients.

Background: The frequency of hand and elbow surgeries occurring in outpatient and elective settings is on the rise. Emergency department (ED) visits in the postoperative period are increasingly used as quality measures for surgical care. The aim of this study is to determine the number of postoperative ED visits, the primary reason for these visits, and to identify risk factors associated with these visits. Methods: We examined all elective hand and elbow procedures performed at two hospitals within a single healthcare network between 2008 and 2017. A total of 3,261 patients met the study criteria. Descriptive statistics were calculated for our population, followed by univariate and multivariate analyses, to identify risk and protective factors associated with ED visits in the first 30 days after surgery. Results: Eighty-seven of 3,261 patients presented to the ED within 30 days of their operation (2.7%). The most common reasons for ED visits were related to pain (28.7%), swelling (26.4%), and concerns for infection (20.7%). Univariate analysis indicated history of drug use, number of procedures, smoking history, and serum albumin <3.5 mg/dL as risk factors for returns to the ED. Multivariate analysis identified history of drug use, number of procedures, and serum albumin <3.5 mg/dL as independent risk factors. Smoking history failed to achieve statistical significance as an independent risk factor. Both univariate and multivariate analyses identified age >60 years as protective for postoperative ED visits. Conclusions: ED visits within the first 30 days after elective hand surgery are relatively common, despite remarkably low complication rates among these procedures. This information may help to improve risk stratification in these patients, and to aid in the development of enhanced postoperative follow-up strategies to reduce unnecessary utilization of emergency medical services. Level of Evidence: Level III (Therapeutic).

Patient-Related Risk Factors Associated With Surgical Site Complications After Elective Hand Surgery.

BACKGROUND: The purpose of this study was to identify independent risk factors associated with an increased rate of surgical site complications after elective hand surgery. METHODS: This study is a retrospective review of all patients who underwent elective hand, wrist, forearm, and elbow surgery over a 10-year period at a single institution. Electronic medical records were reviewed, and information regarding patient demographics, past medical and social history, perioperative laboratory values, procedures performed, and surgical complications was collected. Surgical site complications included surgical site infections, seromas or hematomas, and delayed wound healing or wound dehiscence. A univariate analysis was then performed to identify potential risk factors, which were then included in a multivariate regression analysis. RESULTS: A total of 3261 patients who underwent elective hand surgery and met the above inclusion and exclusion criteria were included in this study. The mean age was 57 years, with 65% female and 35% male patients. The overall surgical complication rate was 2.2%. Univariate analysis of patient factors identified male sex; number of procedures >1; history of drug, alcohol, or smoking use; American Society of Anesthesiologists (ASA) class III and IV; and serum albumin <3.5 mg/dL to be significantly associated with complications. However, multivariate regression analysis identified that only ASA class III and IV (odds ratio = 3.27) was significantly associated with surgical complications. CONCLUSIONS: Patients classified as ASA class III or IV were identified to be at a significantly increased risk of complications following elective hand surgery. Health factors which triage patients into these 2 groups may represent potentially modifiable factors to mitigate perioperative risk in the elective hand surgery population.

Effect of Smoking on Short-term Postoperative Complications After Elective Upper Extremity Surgery.

Background: There is a paucity of literature exploring the impact of smoking on short-term complications, readmissions, and reoperations after elective upper extremity surgery using a large multicenter national database. We hypothesized that smokers will have an increased rate of complications, readmissions, and reoperations compared with a cohort of nonsmokers undergoing elective upper extremity surgery. Methods: Patient data were collected from the American College of Surgeons National Surgical Quality Improvement Program database between the years 2012 and 2017. Patients were included if they underwent elective surgery of the upper extremity using 338 predetermined Current Procedural Terminology codes. The data collected were divided into patient demographics, comorbidities, perioperative variables, and 30-day complications. Current smoking status was defined as smoking within 1 year prior to surgery. The incidence of surgical complications, reoperations, and readmissions was compared between the 2 cohorts using multivariable regression analysis. Results: Of the 107 943 patients undergoing elective surgeries of the upper extremity, 73 806 met the inclusion criteria. Of these, 57 986 (78.6%) were nonsmokers in the year prior to surgery, and 15 820 (21.4%) were current smokers. Between these groups, current smokers were younger (P < .001), more often men (P < .001), had lower body mass index (P < .001), and more often underwent procedures that involved bone manipulation (P < .001). Multivariate regression analysis defined current smoking as significantly associated with overall surgical site complications, superficial surgical site infections, deep surgical site infections, reoperation, and readmission. Conclusion: Current smoking was significantly associated with an increase in all surgical site complications, readmissions, and reoperations after elective upper extremity surgery. Surgeons should consider smoking a modifiable risk factor for postoperative complications and appropriately counsel patients on outcomes and complications given the elective nature of upper extremity surgery.

Effect of Diabetes and Hemoglobin A1c on Complications Following Elective Hand Surgery.

Background: Limited research exists investigating the association between diabetes and glycemic control on complications following elective hand surgery. The goal of this research was to assess the incidence of complications within 30 days of elective hand surgery in a large population of diabetic patients compared to a population of non-diabetics. Furthermore, we sought to examine the relationship of glycemic control, as measured by HbA1c, and postoperative complications. Methods: We performed a retrospective review of electronic medical records at our institution of all patients who underwent elective hand, forearm, or elbow surgery from the dates of January 1st, 2008 to December 31st, 2017. Patients were categorized as diabetic or non-diabetic and most recent HbA1c was documented. Multivariable analysis was employed to compare the incidence of surgical complications within 30 days between the diabetics and non-diabetic populations, adjusting for baseline patient characteristics. Results: A total of 3,261 patients met the inclusion criteria. There were 646 (20%) diabetic patients and 2,615 (80%) non-diabetic patients. No difference was found in the overall rate of complications between the cohort of diabetic and non-diabetic patients. Additionally, statistical analysis found no difference in the complication rate between insulin and non-insulin controlled diabetics. Rates of complications were stratified based on HbA1c level and statistical analysis found no increased risk of complications with increased hemoglobin A1c value. Conclusions: In our present study we were not able to demonstrate any significant difference in the 30 day complication rates between and non-diabetics undergoing elective hand surgery. This study attempted to aid in risk stratification of diabetic patients by evaluating preoperative glycemic indices in the form of HbA1c.

Distal Radius Fractures and the Dorsal Spanning Plate in the Management of the Polytraumatized Patient.

SUMMARY: Distal radius fractures are some of the most common fractures treated by the orthopaedic surgeon. There are a variety of methods of fixation to treat these fractures; however, in patients with polytrauma and in high-energy fracture patterns, fixation options can be limited. In the past, these fractures were treated with plaster, Kirschner wires, or external fixators that were fraught with complications. The dorsal spanning plate is an excellent option in the treatment of high-energy fractures and patients with polytrauma, fractures with dorsal or volar comminution, fracture dislocations, and shear injuries, and in geriatric patients with poor bone quality. The dorsal spanning plate not only allows for fixation of these complex fractures but also allows for weight-bearing through the wrist, an advantage for patients with concomitant lower extremity fractures and geriatric patients who need mobility aides. Understanding the risks and benefits of dorsal spanning plates and their use for the treatment of polytraumatized patient is a vital base of knowledge for the orthopaedic traumatologist.

Acceptance and Change as Dialectic of Recovery: Examples of Storytelling, Fairy Tale and Psychopharmacotherapy as Therapeutic Modalities.

"Narative medicine" promotes theraputic healing and recovery using fairy tales and traditional folk stories. Individuals are capable of shaping their lives through various narrative strategies and re-authoring alternative stories that are concerned with different aspects of acceptance and change. Psychotherapy through the eyes of stories and fairy tales can have two perspectives. Firstly, fairy tale acts like a weft around which the very story/script of the patient is formed, which in itself becomes the basis for interpreting the occurrence of a mental disorder. The second perspective is the perspective of healing or getting out of a "fairytale" story/script by changing an incoherent life narrative into an alternative coherent narrative (reframing). The aim of this pilot case studies approach was to use a narrative approach based on stories and fairy tales in order to promote psychological growth, meaning in life, resilience, self-realization and improved well-being and highlight the dialectic of recovery, an interplay of acceptance and change (reframing). With properly applied personalized narrative psychopharmacotherapy, the patient is capable of changing their beliefs in order to reach a new meaning of life, and thus to facilitate the lowering of symptomatology, its dissaperance and possibly even a cure, whatever that may mean for an individual. Considering its promising results, clinical implications and possible further applications are discussed.

Emotional complexity across the life story: Elevated negative emodiversity and diminished positive emodiversity in sufferers of recurrent depression.

BACKGROUND: Greater diversity in the experience of negative and positive emotions - emodiversity - is associated with better mental health outcomes in the general population (Quoidbach et al. 2014). However, conceptual accounts of depression suggest this might differ in clinical depression. In this study, the diversity of negative and positive emotion experiences as remembered by a recurrently depressed sample and a never-depressed control group were compared. METHODS: Emodiversity was assessed using a life structure card sort task which allowed for the assessment of memory for emotional experience over the life course. Depressed (n=34) and non-depressed (n=34) participants completed the card sort task, from which emodiversity metrics were calculated for negative and positive emotion experience. RESULTS: Depressed individuals showed recollections of enhanced emodiversity across negative emotion but reduced emodiversity across positive emotion, relative to never-depressed individuals. LIMITATIONS: This study involved a relatively small sample size. DISCUSSION: This study indicates that greater diversity of negative emotion experience, which has been interpreted as a protective factor against depressed mood in community samples (Quoidbach et al., 2014), instead characterises the remembered experience of recurrent clinical depression. The finding that positive emodiversity is adaptive in depression suggests that therapeutic outcomes may be improved by facilitating exposure to a diverse range of positive emotions. These findings indicate that the relationship between emotion diversity and mental health is more complex than hitherto assumed.

Personally salient, emotionally negative task contexts provoke goal neglect in depression.

BACKGROUND: Goal neglect refers to a dissociation between intended and actual action. Although commonly associated with frontal brain damage, this phenomenon is also characteristic of clinical depression. To date, tests of goal neglect typically require individuals to switch between subtasks populated with neutral stimuli. This study examined the impact of affective and personally salient stimulus contexts on goal neglect in clinical depression. METHODS: Participants were randomly allocated to either positively or negatively-valenced versions of the Affective Six Elements Test (A-SET). We hypothesised that depressed individuals (n = 30) would exhibit an overall impairment in A-SET performance by neglecting entire subtasks and allocating suboptimal time to each task, relative to never-depressed peers (n = 30), with effects being strongest for the negatively-valenced version. RESULTS: Findings showed that depressed individuals exhibited specific deficits, relative to controls on these measures in the negative A-SET only, with a magnitude comparable to that found in brain injured patients. CONCLUSIONS: Individuals with depression are impaired in their ability to monitor performance and implement strategies that are optimal for the purpose of pursuing an overarching goal when the task context is negatively-valenced. Potential mechanisms are discussed.

Memory category fluency, memory specificity, and the fading affect bias for positive and negative autobiographical events: Performance on a good day-bad day task in healthy and depressed individuals.

In mentally healthy individuals, autobiographical memory is typically biased toward positive events, which may help to maintain psychological well-being. Our aim was to assess a range of important positive memory biases in the mentally healthy and explore the possibility that these biases are mitigated in those with mental health problems. We administered a novel recall paradigm that required recollection of multiple good and bad past events (the Good Day-Bad Day task) to healthy and depressed individuals. This allowed us to explore differences in memory category fluency (i.e., the ability to generate integrated sets of associated events) for positive and negative memories, along with memory specificity, and fading affect bias-a greater reduction in the intensity of memory-related affect over time for negative versus positive events. We found that healthy participants demonstrated superior category fluency for positive relative to negative events but that this effect was absent in depressed participants. Healthy participants exhibited a strong fading affect bias that was significantly mitigated, although still present, in depression. Finally, memory specificity was reduced in depression for both positive and negative memories. Findings demonstrate that the positive bias associated with mental health is maintained by multiple autobiographical memory processes and that depression is as much a function of the absence of these positive biases as it is the presence of negative biases. Results provide important guidance for developing new treatments for improving mental health. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

The Impact of Affective Context on Autobiographical Recollection in Depression.

Across two studies we investigated the influence of contextual cues on autobiographical memory recall. In Study 1, participants (N = 37) with major depressive disorder, in episode or in varying degrees of remission, were administered a Negative Autobiographical Memory Task (NAMT) that required them to retrieve negatively valenced memories in response to positive cue words (a positive context). We reasoned that increased depression symptom severity would be associated with a reduced ability to override priming from this disadvantageous context. Consequently, we hypothesized that increased depressive severity would counterintuitively be associated with reduced negativity ratings for retrieved personal memories to positive cues on the NAMT. This hypothesis was supported. Study 2, using a community sample (N = 63), demonstrated that a similar reduction in memory negativity was observed in individuals with lower working memory capacity-an index of executive control. Implications for autobiographical memory and executive training paradigms for depression are discussed.

Impact of culture on autobiographical life structure in depression.

OBJECTIVES: Distortions in autobiographical memory have been implicated in major depressive disorder (MDD). Those with MDD demonstrate a 'depressogenic' autobiographical life structure. Research has not examined how culture influences this process. We investigated whether Malay individuals (members of an interdependent culture) with MDD demonstrated a 'depressogenic' autobiographical life structure similar to that of British individuals (members of an independent culture) with MDD. DESIGN: A 2 (Culture; Malay, British) × 2 (Mood; depressed, control) cross-sectional design using a card sort task and self-report measures was used. METHODS: Malay individuals with MDD or no history of MDD completed the life-structure card-sorting task, which provided a novel method for investigating organizational structure of the life narrative. These data were compared to previously collected data in which British individuals with MDD or without MDD had completed the same task within the same experimental protocol. RESULTS: Pan-culturally those with MDD had greater negativity (i.e., used more negative attributes), negative redundancy (i.e., used the same negative attributes repeatedly across life chapters) and negative emodiversity (i.e., had greater variety and relative abundance of negative attributes), and reduced positive redundancy (i.e., used the same positive attributes repeatedly across chapters) in their structuring relative to controls. While the British MDD group had greater compartmentalization (i.e., the negative and positive attributes were clustered separately across different chapters) than British controls, the Malay MDD group had lower levels of compartmentalization than Malay controls. CONCLUSIONS: The findings suggest culture may shape aspects of the autobiographical life structure in MDD. PRACTITIONER POINTS: The majority of the literature investigating depression pertains to individuals from European Western cultures, despite recognition that depression ranks as one of the most debilitating diseases worldwide. This raises questions as to whether current depression models and interventions can be applied universally or whether they are limited to European Western groups. The current study found that pan-culturally those with MDD had similar structuring of their life story relative to controls. However, there were some cultural differences that need to be considered (e.g., Malay individuals provided less detailed, less elaborate and less emotionally diverse life stories and while the British MDD group had greater compartmentalization than British controls, the Malay MDD group had lower levels of compartmentalization than Malay controls). Limitations of the study included group differences in gender and mood at the time of testing. Cultural differences in the number of attributes used may have influenced findings. Only the Malay group completed the individualism-collectivism measure.

Affective enhancement of working memory is maintained in depression.

We currently know little about how performance on assessments of working memory capacity (WMC) that are designed to mirror the concurrent task demands of daily life are impacted by the presence of affective information, nor how those effects may be modulated by depression-a syndrome where sufferers report global difficulties with executive processing. Across 3 experiments, we investigated WMC for sets of neutral words in the context of processing either neutral or affective (depressogenic) sentences, which had to be judged on semantic accuracy (Experiments 1 and 2) or self-reference (Experiment 3). Overall, WMC was significantly better in the context of depressogenic compared with neutral sentences. However, there was no support for this effect being modulated by symptoms of depression (Experiment 1) or the presence of recurrent major depressive disorder (MDD; Experiments 2 and 3). Implications of these findings for cognitive theories of the role of WM in depression are discussed in the context of a growing body of research showing no support for a differential impact of depressogenic compared with neutral information on WM accuracy.

Facets of pejorative self-processing in complicated grief.

OBJECTIVE: Complicated grief (CG) has been proposed as a psychiatric response to bereavement distinct from established mood and anxiety disorder diagnoses. Little is known about the nature of cognitive-affective processing in CG, nor any similarities or differences compared with the processing profiles associated with other emotional disorders. Three studies therefore investigated 3 broad facets of negative self-processing associated with either elevated symptoms of, or diagnosis of, CG--namely, self-related attributions or blame, self-devaluation, and cognitions about the future self. METHOD: These self-processing domains were assessed using a variety of self-report and scenario-based measures either linked specifically to the bereavement or more general in their focus. Study 1 used a correlational design in a community bereaved sample. Study 2 employed an extreme-groups approach looking at individuals high versus low in CG symptoms, and Study 3 compared those with a CG diagnosis to healthy bereaved controls. RESULTS: The data revealed a profile of processing in CG characterized by significant relationships between CG symptoms or diagnosis and both self-devaluation and negative self-related cognitions about the future, but the data provided no support for a similar relationship with negative self-related attributions. CONCLUSIONS: These findings extend our understanding of self-related cognitive processing in CG. They also suggest that CG is characterized by a cognitive-affective processing profile that is distinct from that associated with other disorders, notably major depression, in the literature. This has potential implications for the psychological treatment of CG and for its nosological status as a post-loss syndrome distinct from depression.

Age shall not weary us: deleterious effects of self-regulation depletion are specific to younger adults.

Self-regulation depletion (SRD), or ego-depletion, refers to decrements in self-regulation performance immediately following a different self-regulation-demanding activity. There are now over a hundred studies reporting SRD across a broad range of tasks and conditions. However, most studies have used young student samples. Because prefrontal brain regions thought to subserve self-regulation do not fully mature until 25 years of age, it is possible that SRD effects are confined to younger populations and are attenuated or disappear in older samples. We investigated this using the Stroop color task as an SRD induction and an autobiographical memory task as the outcome measure. We found that younger participants (<25 years) were susceptible to depletion effects, but found no support for such effects in an older group (40-65 years). This suggests that the widely-reported phenomenon of SRD has important developmental boundary conditions casting doubt on claims that it represents a general feature of human cognition.

The structure of past and future lives in depression.

This study assessed the organization of past autobiographical knowledge in individuals with either current major depressive disorder (MDD), MDD in remission, or no history of MDD (the control group). Participants generated personal lists of "life chapters," dividing both their past and potential future into subjectively meaningful episodes or themes (e.g., "married life"). They were then given a list of potentially chapter-descriptive positive or negative attributes and sorted them according to the different chapters. Results revealed that, relative to the control group, MDD participants selected more negative attributes overall, showed greater redundancy for negative attributes (i.e., using the same ones repeatedly across chapters) and reduced redundancy for positive attributes, and exhibited greater compartmentalization (i.e., the negative and positive attributes were clustered separately across different chapters). A similar pattern emerged for the remitted MDD group relative to controls, with the exception of negative redundancy, which was not elevated. For future chapters, there were no group differences. Finally, a greater number of past depressive episodes was associated with increasingly reduced positive redundancy. These data reveal a "depressogenic" structuring of past (but not future) knowledge in MDD that is also evident in a remitted MDD group, with the exception of negative redundancy, which appears to be a marker of the acute state. These findings shed light on important aspects of the organization of past knowledge that are likely to be linked to maladaptive processing biases in those with a depression history.

Is prolonged grief distinct from bereavement-related posttraumatic stress?

Prolonged grief disorder (PGD) (previously called complicated grief (CG)) is proposed as a distinct post loss syndrome, with its own core symptoms. A key issue concerning the diagnostic validity of PGD is whether it can reliably be distinguished from related psychiatric outcomes following bereavement. This study therefore sought to determine whether the core symptoms of PGD could be distinguished from those of bereavement-related anxiety, depression and posttraumatic stress disorder (PTSD). Data were derived from a community sample of 223 bereaved adults in Croatia. PGD symptomatology was measured using the Revised Inventory of Complicated Grief. Depression and anxiety symptoms were measured using the Beck Depression and Anxiety Inventories, respectively. The intrusion and avoidance symptoms of PTSD were assessed using the Revised Impact of Event Scale. The distinctiveness of the five symptom clusters was examined using principal component analysis (PCA). Symptoms of prolonged grief, depression, anxiety, PTSD-intrusion, and PTSD-avoidance clustered together into five distinct factors. These results support the phenomenological distinctiveness of prolonged grief symptoms, from those of bereavement-related anxiety, depression and, for the first time, PTSD.

Reduced specificity of emotional autobiographical memories following self-regulation depletion.

The present study used a Color Stroop task, involving naming the ink colors of incongruous color words, to deplete self-regulation resources prior to retrieving a series of autobiographical memories to emotional and neutral cue words--the Autobiographical Memory Test (AMT). Control participants either read color words written in black ink or performed no task prior to the AMT. Difficulty accessing specific memories on the AMT has been shown to index key aspects of the onset and maintenance of depression and other emotional disorders. Our hypothesis that depleted participants would retrieve fewer specific memories to cues on the AMT relative to controls was supported, even when levels of depressed and anxious mood, an index of clinical depression, posttraumatic stress, and verbal intelligence were covaried. The results indicate that self-regulation depletion via a neutral, unrelated task can impact on emotion-related autobiographical memory processes that have been shown to be dysfunctional in emotionally disordered populations.
