RESUMEN
BACKGROUND: Tendinopathy, enthesopathy, labral degeneration, and pathologic conditions of the articular disc (knee meniscus and ulnocarpal) are sometimes described in terms of inflammation or damage, while the histopathologic findings are often consistent with mucoid degeneration. A systematic review of the histopathology of these structures at diverse locations might reconceptualize these diseases as expected aspects of human aging. The potential benefits of this evolution might include healthier patient and clinician mindsets as well as a reduced likelihood of overdiagnosis and overtreatment resulting from greater awareness of base rates of pathology. QUESTION/PURPOSE: In this systematic review of studies of surgical specimens, we asked: Are there are any differences in the histopathologic findings of structural soft tissue conditions (mucoid degeneration, inflammation, and vascularity) by anatomic site (foot, elbow, or knee) or structure (tendon body, muscle or tendon origin or insertion [enthesis], labrum, or articular disc)? METHODS: Studies between 1980 and 2021 investigating the histopathologic findings of specimens from surgery for trigger digit, de Quervain tendinopathy, plantar fasciitis, lateral and medial elbow enthesopathy, rotator cuff tendinopathy, posterior tibial tendinopathy, patellar tendinopathy, Achilles tendinopathy, or disease of the hip labrum, ulnocarpal articular disc, or knee meniscus were searched for in the PubMed, EMBASE, and CINAHL databases. Inclusion criteria were the prespecified anatomic location or structure being analyzed histologically and any findings described with respect to inflammation, vascularity, or mucoid degeneration. Studies were excluded if they were nonhuman studies or review articles. Search terms included "anatomy," "pathology," and "histopathology." These terms were coupled with anatomic structures or disorders and included "trigger finger," "de Quervain," "fasciitis, plantar," "tennis elbow," "rotator cuff tendinopathy," "elbow tendinopathy," "patellar tendonitis," "posterior tibial tendon," and "triangular fibrocartilage." This resulted in 3196 studies. After applying the inclusion criteria, 559 articles were then assessed for eligibility according to our exclusion criteria, with 52 eventually included. We recorded whether the study identified the following histopathologic findings: inflammatory cells or molecular markers, greater than expected vascularity (categorized as quantitative count, with or without controls; molecular markers; or qualitative judgments), and features of mucoid degeneration (disorganized collagen, increased extracellular matrix, or chondroid metaplasia). In the absence of methods for systematically evaluating the pathophysiology of structural (collagenous) soft tissue structures and rating histopathologic study quality, all studies that interpreted histopathology results were included. The original authors' judgment regarding the presence or absence of inflammation, greater than expected vascularity, and elements of mucoid degeneration was recorded along with the type of data used to reach that conclusion. RESULTS: Regarding differences in the histopathology of surgical specimens of structural soft tissue conditions by anatomic site, there were no differences in inflammation or mucoid degeneration, and the knee meniscus was less often described as having greater than normal vascularity. There were no differences by anatomic structure. Overall, 20% (10 of 51) of the studies that investigated for inflammation reported it (nine inflammatory cells and one inflammatory marker). Eighty-three percent (43 of 52) interpreted increased vascularity: 40% (17 of 43) using quantitative methods (14 with controls and three without) and 60% (26 of 43) using imprecise criteria. Additionally, 100% (all 52 studies) identified at least one element of mucoid degeneration: 69% (36 of 52) reported an increased extracellular matrix, 71% (37 of 52) reported disorganized collagen, and 33% (17 of 52) reported chondroid metaplasia. CONCLUSION: Our systematic review of the histopathology of diseases of soft tissue structures (enthesopathy, tendinopathy, and labral and articular disc) identified consistent mucoid degeneration, minimal inflammation, and imprecise assessment of relative vascularity; these findings were consistent across anatomic sites and structures, supporting a reconceptualization of these diseases as related to aging (senescence or degeneration) rather than injury or activity. CLINICAL RELEVANCE: This reconceptualization supports accommodative mindsets known to be associated with greater comfort and capability. In addition, awareness of the notable base rates of structural soft tissue changes as people age might reduce overdiagnosis and overtreatment of incidental, benign, or inconsequential signal changes and pathophysiology.

BACKGROUND: Accurately distinguishing the severity of pathophysiology from the level of symptom intensity and incapability is a foundation of effective treatment strategies under the biopsychosocial paradigm of illness. With respect to idiopathic median neuropathy at the carpal tunnel (the symptoms and signs of which are referred to as carpal tunnel syndrome), surgeons who are more likely to recommend surgery based on the magnitude of symptoms and incapability rather than the severity of neuropathy may be underappreciating and undertreating mental health opportunities and overtreating mild, and on occasion unmeasurable, disease. A survey-based experiment that randomizes elements of the patient presentation can help determine the relative influence of magnitude of incapability on ratings of pathology severity. QUESTION/PURPOSE: What factors are associated with severity rating of idiopathic median neuropathy at the carpal tunnel on an 11-point ordinal scale? METHODS: One hundred eight hand and wrist members of the Science of Variation Group (among approximately 200 participants who complete at least one survey-experiment a year related to the upper extremity on average) reviewed seven scenarios of fictional median neuropathy with seven randomized variables: age, gender, limitations of daily activity (incapability), Tinel and Phalen test results, duration of numbness episodes, prevention of numbness with nocturnal splint immobilization, constant numbness, and weakness of palmar abduction. Participants had a mean age of 51 ± 10 years, 90% (97 of 108) were men, and 74% (80 of 108) were subspecialized in hand surgery. Surgeons were asked to rate the severity of idiopathic median neuropathy at the carpal tunnel on a on an 11-point ordinal scale. Factors associated with rated severity were sought in multilevel ordered logistic regression models. Fifteen surgeons did not complete all of their assigned randomized scenarios, resulting in a total of 675 ratings. RESULTS: After controlling for potentially confounding variables such as magnitude of incapability, factors associated with severity rating on the 11-point ordinal scale included palmar abduction weakness (odds ratio 11 [95% confidence interval 7.7 to 15]), longer duration of symptom episodes (OR 4.5 [95% CI 3.3 to 6.2]), nocturnal numbness in spite of splint immobilization (OR 3.2 [95% CI 2.3 to 4.3]), constant numbness (OR 2.5 [95% CI 1.9 to 3.4]), positive Tinel and positive Phalen test results (OR 2.2 [95% CI 1.6 to 2.9]), and older age (OR 1.6 [95% CI 1.2 to 2.1]). CONCLUSION: Our results suggest that surgeons rate the severity of idiopathic median neuropathy at the carpal tunnel based on evidence of worse pathophysiology and are not distracted by greater incapability. CLINICAL RELEVANCE: Surgeons who consider greater incapability as an indication of more severe pathology seem to be practicing outside the norm and may be underappreciating and undertreating the unhelpful thoughts and feelings of worry or despair that consistently account for a notable amount of the variation in symptom intensity and magnitude of incapability.

OBJECTIVE: We investigated communication strategies clinicians reported using to navigate differences of opinion with patients regarding medical decisions. METHODS: Twenty physicians of various specialties participated in semi-structured interviews regarding their strategies for maintaining mutual respect when disagreeing with a patient. Reflexive thematic analysis was applied. Enrollment concluded upon theme saturation. RESULTS: In an attempt to limit disagreements, physicians learned to gauge patient values, often deferring to clinicians being the expert on medicine and patients being the expert on themselves. Physicians noticed that disagreements were reinforced by prioritizing educational approaches. Strengthening the relationship by validating patient emotions was seen as a more effective strategy. Clinicians found it difficult to weigh relative potential for benefit to the relationship and feelings of moral distress in capitulating to patient preferences they disagreed with. CONCLUSION: Physicians recognized the value of moving from educational to relationship building strategies to help limit and navigate disagreements. Key strategies include prioritizing gauging the patient's values and validating their emotions. PRACTICE IMPLICATIONS: Anticipating disagreement, training clinicians to limit teaching, and instead prioritize a strong relationship to maintain trust and collaboration has the potential to improve patient health, with more limited resource use, and better experiences of care.

Objective: Patients might exaggerate their symptoms in an attempt to align the clinician's views with their own. A person who sees potential benefit in symptom exaggeration might also experience less trust, more difficulty communicating, and lower satisfaction with their clinician. We asked if there was an association between patient rating of communication effectiveness, patient satisfaction, and patient trust with symptom exaggeration? Methods: One hundred and thirty-two patients in four orthopaedic offices completed surveys including demographics, Communication-Effectiveness-Questionnaire (CEQ-6), Negative-Pain-Thoughts-Questionnaire (NPTQ-4), a Guttman-style satisfaction question, PROMIS Depression, and Stanford Trust in Physician. Patients were randomly assigned to answer three questions about symptom exaggeration for two scenarios: 1) their own exaggeration during the just-completed visit or 2) the average person's tendency to exaggerate. Results: In multivariable analysis, lower ratings of communication effectiveness were associated with greater symptom exaggeration (p=0.002), while an annual household income>$100,000 (p=0.033) was associated with higher ratings. Higher rating of satisfaction was associated with lower education attained (p=0.004). Greater trust was associated with lower personal exaggeration (p=0.002). Conclusion: The relationship between greater exaggeration and lower ratings of communication effectiveness and trust suggests that symptom descriptions that seem more intense or diffuse than expected may indicate opportunities for more effective communication and trust. Innovation: Patient experience can be improved by training clinicians to identify symptom exaggeration as a signal that the patient does not feel heard and understood and a cue to return to communication strategies that build trust.
RESUMEN
The emergence of carbapenem-resistant Escherichia coli (CREC) especially harboring the New Delhi Metallo-ß-lactamase (blaNDM) variants are increasingly being reported from many countries, however, the data from Pakistan is limited. In the present study, 109 CREC isolates were obtained from 4,091 E. coli isolates in five tertiary care hospitals in southern Punjab, Pakistan. The antimicrobial susceptibility profiling and screening for the resistance determinants were performed followed by blaNDM typing and multilocus sequence typing (MLST) to characterize the CREC strains. Among the carbapenemases, 57 CREC isolates were found to harbor blaNDM. The blaNDM-1, blaNDM-5, blaNDM-7, and blaNDM-4 variants were identified in 30 (52.6%), 18 (31.6%), (12.3%), 2 (3.5%) isolates, respectively. The ESBL genes, such as blaCTX-M and blaTEM, were also found in different combinations, whereas the 16S methylases that is, rmtB and armA were found in 69 (63.3%) and 55 (50.5%) CREC isolates, respectively. The MLST of blaNDM carrying E. coli revealed eight different sequence types (STs) with ST131 belonging to 21 isolates being the most prevalent. The clonal complex 131 was the predominant complex corresponding to 47 (82.5%) of blaNDM-positive strains. Large-scale surveillance studies coupled with active infection control policies are suggested on an urgent basis to avoid an epidemic in the future.

One of the primary means through which people protect themselves and their loved ones from COVID-19 is by communicating with others, as they discuss preventive health behaviors and make decisions about safe social interaction. These conversations are sometimes quite challenging. Guided by the conceptual lens of communication work, this study was an investigation of how communication during the pandemic was experienced by people as work. Findings validated and extended the communication work construct. Communication during the pandemic is effortful because it is high stakes, relentless, and takes an emotional toll. Nonetheless, many people feel a sense of responsibility and obligation to have these conversations. Communication about COVID-19 is divisible labor that can be shared. People engage in strategic preparation and message design to accomplish multiple goals before, during, and after discussions about pandemic topics.
