Artificial intelligence can be used in the identification and classification of shoulder osteoarthritis and avascular necrosis on plain radiographs: a training study of 7,139 radiograph sets.

BACKGROUND AND PURPOSE: Knowledge concerning the use AI models for the classification of glenohumeral osteoarthritis (GHOA) and avascular necrosis (AVN) of the humeral head is lacking. We aimed to analyze how a deep learning (DL) model trained to identify and grade GHOA on plain radiographs performs. Our secondary aim was to train a DL model to identify and grade AVN on plain radiographs. PATIENTS AND METHODS: A modified ResNet-type network was trained on a dataset of radiographic shoulder examinations from a large tertiary hospital. A total of 7,139 radiographs were included. The dataset included various projections of the shoulder, and the network was trained using stochastic gradient descent. Performance evaluation metrics, area under the receiver operating characteristic curve (AUC), sensitivity, and specificity were used to assess the network's performance for each outcome. RESULTS: The network demonstrated AUC values ranging from 0.73 to 0.93 for GHOA classification and > 0.90 for all AVN classification classes. The network exhibited lower AUC for mild cases compared with definitive cases of GHOA. When none and mild grades were combined, the AUC increased, suggesting difficulties in distinguishing between these 2 grades. CONCLUSION: We found that a DL model can be trained to identify and grade GHOA on plain radiographs. Furthermore, we show that a DL model can identify and grade AVN on plain radiographs. The network performed well, particularly for definitive cases of GHOA and any level of AVN. However, challenges remain in distinguishing between none and mild GHOA grades.

Timing of Surgery for Proximal Humeral Fracture Treated with Shoulder Hemiarthroplasty, Best Results with Surgery Within 2 Weeks.

Background: Preoperative delay may affect the outcome of proximal humerus fractures treated with shoulder hemiarthroplasty. There is currently no consensus for the recommended preoperative time interval. The aim was to examine how the time to surgery with shoulder hemiarthroplasty after a proximal humerus fracture affected the patient-reported outcome. Methods: 380 patients with proximal humerus fractures treated with shoulder hemiarthroplasty recorded from the Swedish Shoulder Arthroplasty Registry were included. Three self-reporting outcome instruments were used at follow-up after 1-5 years: a shoulder-specific score, the Western Ontario Osteoarthritis of the Shoulder index (WOOS), the EuroQol-5 Dimension index (EQ-5D), and subjective patient satisfaction assessment. Results: The preoperative delay had a negative impact on the WOOS, EQ-5D, and patient satisfaction level (p < 0.01). The best result, measured with WOOS at a minimum 1-year follow-up, was found when surgery was performed 6-10 days after the reported date of fracture. WOOS% 8-14 days was 69.4% (± 24.2). A delay of more than 10 days was shown to be correlated with poorer outcomes. WOOS% 15-60 days was 55.8% (± 25.0) and continued to decrease. Conclusion: The current recommendation in Sweden to perform shoulder hemiarthroplasty within 2 weeks after sustaining a proximal humerus fracture is considered valid.

Deep learning classification of shoulder fractures on plain radiographs of the humerus, scapula and clavicle.

In this study, we present a deep learning model for fracture classification on shoulder radiographs using a convolutional neural network (CNN). The primary aim was to evaluate the classification performance of the CNN for proximal humeral fractures (PHF) based on the AO/OTA classification system. Secondary objectives included evaluating the model's performance for diaphyseal humerus, clavicle, and scapula fractures. The training dataset consisted of 6,172 examinations, including 2-7 radiographs per examination. The overall area under the curve (AUC) for fracture classification was 0.89, indicating good performance. For PHF classification, 12 out of 16 classes achieved an AUC of 0.90 or greater. Additionally, the CNN model had excellent overall AUC for diaphyseal humerus fractures (0.97), clavicle fractures (0.96), and good AUC for scapula fractures (0.87). Despite the limitations of the study, such as the reliance on ground truth labels provided by students with limited radiographic assessment experience, our findings are in concordance with previous studies, further consolidating CNN as potent fracture classifiers in plain radiographs. The inclusion of multiple radiographs with different views from each examination, as well as the generally unselected nature of the sample, contributed to the overall generalizability of the study. This is the fifth study published by our group on AI in orthopaedic radiographs, which has consistently shown promising results. The next challenge for the orthopaedic research community will be to transfer these results from the research setting into clinical practice. External validation of the CNN model should be conducted in the future before it is considered for use in a clinical setting.

Observing and interpreting clinical process: Methods and findings from 'Layered analysis' of parent-infant psychotherapy.

This paper describes a method for investigating clinical process, Layered Analysis, which combines therapist countertransference reports and multi-faceted microanalytic research approaches. Findings from the application of Layered Analysis to video-recorded micro-events of rupture and repair in four psychoanalytic parent-infant psychotherapy sessions are presented. Layered analysis showed that countertransference and observation are complementary perspectives, which enable concomitant study of interactive events, conscious internal experiences, as well as nonconscious and unconscious elements of therapeutic interaction. Interactional rupture and repair were found to constitute co-constructed micro-events that occurred fleetingly and often implicitly, and differed in the structure, coherence and flow of interactions and in the relationship between verbal and nonverbal communication. Furthermore, interactional ruptures were found to sometimes 'get into' the therapist and transiently disrupt their self-organization, such that the therapist became a locus of disruption for the patient(s), actively contributing to the rupture, which thus became embedded in the therapeutic system. Interactive repair was found to be most often initiated by the therapist and to be underpinned by the therapist re-establishing self-regulation, through metabolizing embodied and verbal aspects of the rupture. Studying such processes can enhance our understanding of clinical process, inform therapist training and clinical supervision, and contribute to clinical outcomes.

Este ensayo describe un método para investigar un proceso clínico, Análisis en Capas, el cual combina los reportes de contratransferencia del terapeuta y los acercamientos investigativos micro analíticos multifacéticos. Se presentan los resultados de aplicar Análisis en Capas a micro eventos, grabados en video, de ruptura y reparación en cuatro sesiones de sicoterapia sicoanalítica de progenitor e infante. Los Análisis en capas mostraron que la contratransferencia y la observación son perspectivas complementarias que, en combinación, permiten el estudio concomitante de eventos interactivos, experiencias internas conscientes, así como elementos no conscientes de la interacción terapéutica. Adicionalmente, los resultados mostraron que la ruptura y la reparación constituyen micro eventos co-construidos que ocurren muy fugazmente y a menudo implícitamente, y que difieren en la estructura, coherencia, flujo de interacciones y en la relación entre la comunicación verbal y no verbal. Es más, rupturas interaccionales pueden 'meterse en' el terapeuta y transitoriamente interrumpir su autoorganización, de manera que el terapeuta se convierte en un punto de interrupción para el paciente y la ruptura pasa a ser parte del sistema terapéutico. La reparación interactiva está sostenida por, y depende de, la metabolización del terapeuta de los aspectos incorporados y verbales de la ruptura. Estudiar tales procesos puede mejorar nuestra comprensión del proceso clínico y ser usado en entrenamiento y supervisión de terapeutas.

Cet article décrit une méthode d'investigation du processus clinique d'Analyse Multidimensionnelle en Couches, qui combine des rapports de contre-transfert du thérapeute et des approches de recherche micro-analytique à facettes multiples. Les résultats de l'application de l'analyse multidimensionnelle en couches à des micro-événements enregistrés à la vidéo de rupture et de réparation dans quatre séances de psychothérapie psychanalytiques parent bébé sont présentés. L'analyse multidimensionnelle en couches a montré que le contre-transfert et l'observation sont des perspectives complémentaires qui, combinés l'un avec l'autre, permettent une étude concomitante d'événements interactifs, d'expériences internes conscientes et d'éléments non-conscients de l'interaction thérapeutique. De plus, les résultats ont montré que la rupture et la réparation constituent des micro-événements co-construits, qui se passent très fugacement et souvent implicitement et diffèrent en structure, cohérence et flux des interactions et dans la relation entre la communication verbale et non verbale. Enfin les ruptures interactionnelles peuvent 'entrer' dans le thérapeute et perturber de façon transitoire leur auto-organisation, de telle manière que le thérapeute devient le locus de la perturbation pour le/la/les patient(e/s) et la rupture s'encastre dans le système thérapeutique. La réparation interactive est étayée par, et elle en dépend également, la métabolisation d'aspects verbaux et incarnés de la rupture du thérapeute. L'étude de tels processus peut améliorer notre compréhension du processus clinique et être utilisée dans la formation et la supervision des thérapeutes.

Western Ontario Osteoarthritis of the Shoulder Index (WOOS) - a validation for use in proximal humerus fractures treated with arthroplasty.

BACKGROUND: The Swedish shoulder and Arthroplasty Registry (SSAR) use the Western Ontario Osteoarthritis of the Shoulder Index (WOOS) as their shoulder-specific score in the follow-up. WOOS is not yet validated for use as the Patient Reported Outcome Measurement (PROM) for proximal humerus fractures (PHF) treated with shoulder hemiarthroplasty (SHA) in the Swedish registry. The aim of this study was to examine the validity, the reliability and the responsiveness of WOOS as a PROM for proximal humerus fractures treated with shoulder arthroplasty. METHODS: Data was collected from the SSAR from the 1st of January 2008 to the 31st of June 2011. A total of 72 subjects were identified with at least 1 year of follow-up. Of these 43 completed all the shoulder-specific PROM together with a clinical examination, including a WOOS retest and general health scores. A group of 29 did not undergo any clinical examination, but they completed all the questionnaires not requiring a clinical examination. The validity was assessed with WOOS compared to satisfaction level, and the Spearman rank coefficient was used for the correlation between WOOS and the shoulder-specific scores (Constant-Murley Score, Oxford Shoulder Score, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form and EQ-5D. For reliability, Intra Class Correlation (ICC) was used for the test-retest assessment and Cronbach´s alpha for the construct reliability. RESULTS: The validity for WOOS had an excellent correlation (> 0.75) with all the shoulder-specific scores and a good correlation (> 0.6) with EQ-5D. The reliability with the test-retest of the total WOOS score and the subgroups had an excellent correlation. Cronbach´s alpha also supports the construct of WOOS. There were no floor or ceiling effects. CONCLUSIONS: We found that WOOS is a reliable tool for evaluating patients with SHA after PHF. Based on our study, we recommend the continued use of WOOS in shoulder arthroplasty registries and observational studies.

The Choice of Antibiotic Prophylaxis Influences the Infection Reoperation Rate in Primary Shoulder Arthroplasty: Analysis From the Swedish Shoulder Arthroplasty Register.

BACKGROUND: Periprosthetic joint infection is a serious complication and a major reason for revision surgery after primary shoulder arthroplasty. The prophylactic antibiotics for primary shoulder arthroplasty that have predominantly been used in Sweden are cloxacillin and clindamycin. To address Cutibacteriumacnes , benzylpenicillin has recently increasingly been added to cloxacillin, but it is unclear which antibiotic prophylaxis regimen is the most effective to prevent periprosthetic joint infection. QUESTIONS/PURPOSES: After controlling for baseline differences among patients such as age, gender, previous surgery, cement fixation, and arthroplasty type, was the risk of reoperation for infection higher in patients who received cloxacillin than in those who received clindamycin or the combination of benzylpenicillin and cloxacillin? METHODS: Data from the Swedish Shoulder Arthroplasty Register were used for this study. The inclusion criterion was registered antibiotic prophylaxis in primary arthroplasty. Between January 1, 1999, and December 31, 2019, 22,470 primary shoulder arthroplasties, including total shoulder, hemiarthroplasty, and reverse shoulder arthroplasties, were entered into the Swedish Shoulder Arthroplasty Register. Reporting of antibiotic prophylaxis to the register was introduced on January 1, 2013. Since then, the completeness of information on the type of antibiotic prophylaxis in the reports has been 85.3%. Consequently, 10,706 arthroplasties were eligible and fulfilled the inclusion criterion of reported antibiotic prophylaxis. A further 129 were excluded because of unusual prophylaxis regimens, leaving 10,577 shoulder arthroplasties for analysis. The Swedish Shoulder Arthroplasty Register gathers information from all 60 hospitals performing shoulder arthroplasty in Sweden, and through a comparison with the National Patient Register, it has been estimated that more than 90% of all primary shoulder arthroplasties and shoulder reoperations are reported to the register. The age of the study population ranged between 16 and 98 years; the mean age at the primary surgery was 70 ± 10 years for the entire cohort, with a mean age of 67 ± 10 years and 72 ± 9 years for men and women, respectively. The mean observation period was 989 ± 669 days. From 2013 to 2019, there was a clear change in prophylaxis; in particular, the use of the combination of benzylpenicillin and cloxacillin increased dramatically and the use of cloxacillin alone decreased. Clindamycin prophylaxis increased moderately. The primary study endpoint was reported reoperation for infection. In the register, this is defined as repeat procedures of any kind, including biopsy, lavage of the joint, or revision, defined as secondary surgery in which a component was exchanged, removed, or added. To compare the reoperation rate in relation to the different antibiotics used, which changed over time, we controlled for age, gender, previous surgery, cement fixation, and arthroplasty type using a Cox proportional hazards model. RESULTS: When adjusting for age, gender, previous surgery, cement fixation, and arthroplasty type, cloxacillin prophylaxis was associated with an increased relative risk of reoperation for infection compared with the combination of cloxacillin and benzylpenicillin (hazard ratio [HR] 2.40 [95% confidence interval (CI) 1.35 to 4.25]; p = 0.003) and compared with clindamycin alone (HR 1.78 [95% CI 1.11 to 2.85]; p = 0.02). No difference was found between the cloxacillin and benzylpenicillin combination and clindamycin (HR 0.74 [95% CI 0.42 to 1.32]; p = 0.31). CONCLUSION: Our results indicate that prophylaxis against C. acnes may be warranted in shoulder arthroplasty. Because the absolute number of infections was low and infections could have been underreported to the register, our results should be interpreted with caution. There is no available information about the causative microorganisms. The study lays the groundwork for further investigations of antibiotic prophylaxis regimens in shoulder arthroplasty. Because large randomized controlled trials would be impractical to perform, prospective register-based randomized controlled studies might be a viable method. LEVEL OF EVIDENCE: Level Ⅲ, therapeutic study.

Psychoanalysis with adults inspired by parent-infant psychotherapy: The analyst's metaphoric function.

This paper investigates a phenomenon observed in parent-infant psychotherapy (PIP). Metaphors emerge in the analyst and, once voiced, they can become tools for understanding the present predicament of mother and/or child. The article contains vignettes from work with a mother and her son, four weeks old when PIP started. They are followed by a vignette of an adult analysand. In both settings, the analyst found himself in an impasse, until he came up with a metaphor expressed to the mother and the analysand, respectively. The paper investigates why PIP experiences might inspire an analyst to suggest metaphors to adult patients as well and thence to understand their suffering better. Aspects of linguistic theory underlining the infantile roots of metaphors are submitted as well as other analysts' views of using metaphors at work. It describes how the validity of a metaphor - whether it expresses something essential about the patient's internal world - should be assessed by following up his/her response to it. It defends the position that metaphor, if used with parsimony and sobriety, is a valuable tool in enabling the patient to map their internal world.

Validity, reliability, and responsiveness of the Swedish version of Western Ontario Osteoarthritis of the Shoulder index.

BACKGROUND: The Western Ontario of the Shoulder index (WOOS) is a patient-reported, disease-specific instrument, designed to measure quality of life in patients with osteoarthritis of the shoulder. The Swedish Shoulder Arthroplasty Registry (SSAR) uses WOOS and EuroQoL 5-dimensions 3 levels (EQ-5D-3L) as patient reported outcome measures. The purpose of this study was to test the validity, responsiveness, and reliability of the Swedish translation of WOOS for patients with osteoarthritis of the shoulder. METHODS: Data was collected from three shoulder arthroplasty studies performed during 2005-2013, with 23, 21, and 19 patients respectively. Forms were collected preoperatively, and postoperatively between 12 and 24 months. WOOS and EQ-5D-3L were used in all three studies. Additionally, the Oxford Shoulder Score (OSS) (n = 23) was used in one study, and the Constant-Murley score (CMS) (n = 40) in two of the studies. Validity was analysed by calculating Pearson's correlation coefficient (PCC). Cronbach's alpha (CA) was used to estimate internal consistency and reliability. The responsiveness of WOOS was measured by calculating effect size and standardized response mean. To assess the performance of WOOS over time, we present repeated measures of WOOS in the registry over a 10-year period. RESULTS: The validity analysis showed excellent correlations of WOOS to CMS, OSS and EQ-5D 3L, with Pearson's correlation coefficient of 0.72, 0.83, and 0.62 respectively (P < 0.001). There were adequate floor effects in the sport and lifestyle domains preoperatively, and adequate ceiling effects in all domains postoperatively. There were no floor effects and adequate ceiling effects for total WOOS. Analyzing reliability, Cronbach's alpha was 0.95 for the pre- and postoperative WOOS scores combined. The analysis of responsiveness for WOOS showed an effect size of 2.52 and a standardized response mean of 1.43. The individual results measured by WOOS within the registry shows stable levels from 1 to 10 years. CONCLUSION: The Swedish translation of WOOS is valid, reliable, and responsive for use in a clinical setting for patients with glenohumeral osteoarthritis treated with shoulder arthroplasty, and we regard it as an appropriate instrument for use in the Swedish Shoulder Arthroplasty Registry.

Gaze avoidance in parent-infant psychotherapy: Manifestations and technical suggestions.

Infants express emotional distress through whining, crying, flailing, silence, etc., which can be viewed as communications that also afflict the caregiver(s). One expressive mode, subtle and often unnoticed except by the parents, is infant gaze avoidance. It often elicits parental feelings of rejection, shame and despair, and may be a reason for seeking parent-infant psychotherapy. In therapy, the symptom often discloses a disturbance in the dyad's emotional interaction. Therapy can bring about relief in the symptom and the relational disorder. Sometimes, the therapist discovers that the infant is avoiding the therapist's, rather than the parents', eyes. This challenges the therapist's expertise in establishing contact with the baby and in perceiving and processing emotional reactions to what may be experienced as the baby's dismissal. Gaze avoidance elicits theoretical questions approached in a previous publication: what does the child seem to avoid in the adult's eyes, and how can we conceptualize the psychodynamics behind the symptom? It also evokes technical questions: how can the therapist make contact with an infant who avoids the mother's or the therapist's eyes? How can the clinician exploit their emotional reactions, the countertransference, to understand and further the dyad's emotional communication? Two case vignettes are provided.

Reverse total shoulder arthroplasty provides better shoulder function than hemiarthroplasty for displaced 3- and 4-part proximal humeral fractures in patients aged 70 years or older: a multicenter randomized controlled trial.

BACKGROUND: The most appropriate treatment for displaced multiple-fragment proximal humeral fractures in elderly patients is currently unclear. Reverse total shoulder arthroplasty (rTSA) is a promising treatment option that is being used increasingly. The purpose of this study was to compare the outcome of rTSA vs. hemiarthroplasty (HA) for the treatment of displaced 3- and 4-part fractures in elderly patients. METHODS: This was a multicenter randomized controlled trial. We included patients aged ≥ 70 years with displaced 3- or 4-part proximal humeral fractures between September 2013 and May 2016. The minimum follow-up period was 2 years, with outcome measures including the Constant score (primary outcome), Western Ontario Osteoarthritis of the Shoulder index, EQ-5D (EuroQol 5 Dimensions) index, and range of motion, as well as pain and shoulder satisfaction assessed on a visual analog scale. RESULTS: We randomized 99 patients to rTSA (48 patients) or HA (51 patients). Fifteen patients were lost to follow-up, leaving 41 rTSA and 43 HA patients for analysis. The mean age was 79.5 years, and there were 76 women (90%). The rTSA group had a mean Constant score of 58.7 points compared with 47.7 points in the HA group, with a mean difference of 11.1 points (95% CI, 3.0-18.9 points; P = .007). Compared with HA patients, rTSA patients had greater mean satisfaction with the shoulder (79 mm vs. 63 mm, P = .011), flexion (125° vs. 90°, P < .001), and abduction (112° vs. 83°, P < .001), but there was no difference in Western Ontario Osteoarthritis of the Shoulder index, pain, or EQ-5D index scores. We identified 3 and 4 adverse events in the rTSA and HA groups, respectively. Among patients aged ≥ 80 years (n = 38), there was no difference between rTSA treatment and HA treatment in pain (17 mm vs. 9 mm, P = .17) or shoulder satisfaction (77 mm vs. 74 mm, P = .73). CONCLUSION: We found that rTSA provides better shoulder function than HA as measured with the Constant score, further emphasized by rTSA patients being more satisfied with their shoulder function. The difference appears to be mainly a result of better range of motion (abduction and flexion) in the rTSA group. The results also indicate that patients aged ≥ 80 years benefit less from rTSA than patients aged 70-79 years.

Short-term psychodynamic infant-parent interventions at Child health centers: Outcomes on parental depression and infant social-emotional functioning.

Randomized controlled trials (RCTs) demonstrate efficacy of parent-infant psychotherapy, but its applicability and effectiveness in public health care are less known. The method followed is Naturalistic study evaluating Short-term Psychodynamic Infant-Parent Interventions at Child Health Centers (SPIPIC) in Stockholm, Sweden. One hundred distressed mothers with infants were recruited by supervised nurses. Six therapists provided 4.3 therapy sessions on average (SD = 3.3). Sessions typically included the mothers, often with the baby present, while fathers rarely attended sessions. The Edinburgh Postnatal Depression Scale (EPDS) and the Ages and Stages Questionnaire: Social-Emotional (ASQ: SE) were distributed at baseline and at 3 and 9 months later. Data from a nonclinical group were collected simultaneously to provide norm data. Multilevel growth models on the mothers' questionnaire scores showed significant decreases over time on both measures. Nine months after baseline, 50% achieved a reliable change on the EPDS and 14% on the ASQ: SE. Prepost effect-sizes (d) were 0.70 and 0.40 for EPDS and ASQ: SE, figures that are comparable to results of other controlled studies. Psychotherapists integrated with public health care seem to achieve good results when supporting distressed mothers with brief interventions in the postnatal period. SPIPIC needs to be compared with other modalities and organizational frameworks.

Los ensayos controlados al azar demuestran lo eficaz de de la sicoterapia progenitor-infante, pero su aplicabilidad y efectividad en el cuidado de la salud pública menos conocidas. Método: Estudio naturalista de evaluación de la Intervención Sicodinámica a Corto Plazo entre Infante y Progenitor en Centros de Salud Infantil (SPIPIC) en Estocolmo, Suecia. Se reclutaron 100 madres afligidas con infantes a través de enfermeras supervisadas. Seis terapeutas proveyeron 4.3 sesiones de terapia en promedio (SD = 3.3). Las sesiones típicamente incluyeron a las madres, a menudo con su bebé presente, mientras que los papás raramente asistieron a las sesiones. Se distribuyeron la Escala de Depresión Postnatal de Edimburgo (EPDS) y el Cuestionario de Edades y Estados: Socio-emocional (ASQ: SE) al punto de partida inicial básico, y a los tres y nueve meses después. Simultáneamente se recogió información de un grupo no clínico con el fin de proveer información de la norma. Resultados: Modelos de crecimiento de niveles múltiples basados en los puntajes de cuestionarios de las madres mostraron significativas bajas a lo largo del tiempo en ambas medidas. Nueve meses después del punto de partida inicial básico, el 50% logró un cambio confiable en la EPDS y 14% en el ASQ; SE. Los tamaños del efecto anterior y posterior (d) fueron 0,70 y 0.40 para la EPDS y el ASQ: SE, lo cual es comparable con resultados estudios controlados. Conclusiones: Los sicoterapeutas integrados con el cuidado de salud pública parecen lograr buenos resultados cuando apoyan a madres afligidas con intervenciones breves perinatalmente. La SPIPIC necesita ser comparada con otras modalidades y marcos de trabajo organizacionales.

Les essais contrôlés randomisés démontrent l'efficacité de la psychothérapie parent-nourrisson mais son application et son efficacité pour le soin de santé publique sont moins connues. Méthode: étude naturelle évaluant l'Intervention Psychodynamique Nourrisson-Parent à Court Terme dans des Centres de Santé de l'Enfant (SPIPIC) à Stockholm en Suède. Cent mères en détresse avec des nourrissons ont été recrutées par des infirmières supervisées. Six thérapeutes ont offerts 4,3 séances thérapeutiques en moyenne (SD = 3,3). Les séances ont typiquement inclus les mères, souvent avec le bébé présent, alors que les pères sont rarement venus aux séances. L'échelle de dépression postnatale d'Edinbourg (EPDS) et le ASQ: SE, questionnaire Etapes et Ages sur le développement socio-développemental et comportemental a été distribué au départ, à trois mois et à neuf mois plus tard. Des données d'un groupe non-clinique ont été collectées simultanément afin d'offrir des données de normes. Résultats: des modèles de croissance multiniveau sur les scores aux questionnaires des mères ont fait preuve de baisses importantes au fil du temps sur les deux mesures. Neuf mois après le départ, 50% ont fait preuve d'un changement important pour ce qui concerne l'EPDS et 14% pour ce qui concerne l'ASQ: SE. Les effets pré-post observés (d) étaient de 0,70 et 0,40 pour l'EPDS et l'ASQ: SE, comparable aux résultats d'études de contrôle. Conclusions: les psychothérapeutes intégrés avec un soin de santé publique semblent être parvenus à de bons résultats alors qu'ils soutenaient les mères en détresse avec de brèves interventions périnatales. Le SPIPIC doit être comparé à d'autres modalités et d'autres structures organisationnelles.

Low arthroplasty survival after treatment for proximal humerus fracture sequelae: 3,245 shoulder replacements from the Nordic Arthroplasty Register Association.

Background and purpose - Proximal humerus fractures (PHF) may result in sequelae indicating arthroplasty. We report cumulative survival rates and reasons for revision after arthroplasty for proximal humerus fracture sequelae (PHFS).Patients and methods - Data were derived from the Nordic Arthroplasty Register Association. The Kaplan-Meier method was used to illustrate survival rates. A scaled Schoenfeld residual plot was used to report the risk of revision for men relative to women in patients who were treated with reverse shoulder arthroplasty (RSA). Revision was defined as removal or exchange of any component or the addition of a glenoid component.Results - 30,190 primary arthroplasties were reported from 2004 to 2016, of which 3,245 were for PHFS. The estimated 1-, 5-, and 10-year cumulative survival rates (95% CI) were 96% (95-97), 90% (89-92), and 86% (83-88) for stemmed hemiarthroplasty and 94% (92-95), 89% (87-91), and 86% (82-90) for RSA with a median time to revision of 18 months (IQR 9-44) and 3 months (IQR 0-17). The risk of revision for men relative to women in patients who were treated with RSA was 3.2 (1.9-5.1) 0-1 year after surgery and 1.9 (0.9-4.1) 1-8 years after surgery. The estimated 1-, 5-, and 10-year cumulative survival rates (95% CI) were 94% (92-96), 88% (85-90), and 80% (75-86) for men and 95% (94-96), 86% (84-89), and 81% (77-84) for young patients.Interpretation - Shoulder arthroplasty for PHFS was associated with lower survival rates, compared with previously published results of shoulder arthroplasty for acute PHF. The low arthroplasty survival rates for men and young patients especially are worrying.

Low risk of revision after reverse shoulder arthroplasty for acute proximal humeral fractures.

BACKGROUND: Reverse shoulder arthroplasty (RSA) has gained popularity in the treatment of proximal humeral fractures (PHFs), especially in elderly patients. The purpose of this study was to investigate the use of RSA implants for acute PHFs and risk of revision, as well as risk factors for revision. METHODS: RSA implants for acute PHFs were identified from the Nordic Arthroplasty Register Association registry data from 2004 to 2016. Kaplan-Meier survival analysis was used to calculate implant survival. Cox multiple regression analysis was used to calculate the adjusted revision rate for sex, age, country of operation, and year of surgery. RESULTS: The study included 1523 RSA implants for PHFs (84% women; average age, 77 years; average follow-up time, 2.5 years). The 5-year cumulative implant survival rate was 97% (confidence limits, 95.5% and 98%). Revision was performed for 33 implants (2%). The most common reason for revision was instability, occurring in 11 cases (0.7%), followed by fracture, occurring in 6 (0.4%), and infection, occurring in 5 (0.3%). Four different arthroplasty brands were used in this cohort, with the Delta Xtend in two-thirds of cases (n = 1025). Age younger than 60 years and male sex were associated with slightly higher rates of revision; however, these differences did not reach statistical significance (hazard ratio of 2.02 with P = .075 and hazard ratio of 3.23 with P = .057, respectively). CONCLUSION: The use of RSA for acute PHFs is increasing in the Nordic countries. The short-term risk of revision is low. The main reason for revision of RSA for this indication is instability.

Psychoanalysis with adults inspired by parent-infant therapy: Reconstructing infantile trauma.

This the first in a series of articles on how Psychodynamic Therapy with Infants and Parents (PTIP) can inspire work with adult therapy. PTIP helps infants and parents improve their relationship and facilitate child development. During sessions, developmental hazards are dramatized by parent and baby, giving the therapist first-hand impressions of how conflictual relationships impact on the well-being of mother and child. This article argues that PTIP experiences may also inspire analytic work with adult patients. (1) It gives the analyst a foothold when reconstructing a patient's infantile trauma and linking it with his/her present distress. (2) It deepens his/her attention on primitive anxieties, para-verbal communication and psychosomatic functioning. (3) PTIP experiences with high-speed interchanges between container and contained, personified by baby and parent, seem to induce more internal images and metaphors in adult work as well. (4) Working with two patients simultaneously means the analyst's position resembles that of a couple therapist or a participant observer of the traffic between container and contained. This can make him/her more agile in dealing with corresponding movements between him/herself and the patient. The present article focuses on (1), reconstructive work in adult work inspired by PTIP experiences.

A hermeneutic study of integrating psychotherapist competence in postnatal Child Health Care: Parents' perspectives.

A child's emotional and social development depends on the parents' provision of optimal support. Many parents with perinatal distress experience difficulties in mastering parenthood and seek help from professionals within primary healthcare. A clinical project was launched in Stockholm, where psychodynamic psychotherapists provided short-term consultations at Child Health Centers. This study qualitatively explored parents' experiences of perinatal distress and of receiving help by nurses and therapists in the project. Thirteen parents were interviewed, and their responses were analyzed with a hermeneutical method. Three main themes crystallized; accessibility of psychological help and detection of emotional problems; experiences of therapy at the Child Health Center; and the therapists' technique. Parents were also clustered into three so-called ideal types: the insecure; parents in crisis; and parents with lifelong psychological problems. Parents experienced obstacles in accessing psychological care within primary healthcare. Psychotherapists with a holistic family perspective and who managed to oscillate between insight-promoting and supportive interventions were especially appreciated. Patient categories who benefitted from insight promotion and support, respectively, were identified.

El desarrollo emocional y social del niño depende de que los padres le brinden un apoyo óptimo. Muchos progenitores con aflicciones perinatales experimentan dificultades al aprender a dominar la crianza y buscan ayuda de profesionales dentro del cuidado de salud de primera instancia. En Estocolmo, se inició un proyecto clínico en el que sicoterapeutas sicodinámicos ofrecieron consultas a corto plazo en los Centros de Salud Infantil. Este estudio exploró cualitativamente las experiencias de aflicciones perinatales de los padres y las de recibir ayuda del cuerpo de enfermería y terapeutas del proyecto. Método: Se entrevistaron trece progenitores y sus respuestas se analizaron con un método hermenéutico. Resultados: Se concretaron tres temas principales: la accesibilidad a ayuda sicológica con detección de problemas emocionales, las experiencias de terapia en los Centros de Salud Infantil, así como las técnicas de los terapeutas. A los progenitores se les agrupó también en tres designados Tipos Ideales: el inseguro, el progenitor en crisis, el progenitor con problemas sicológicos a lo largo de la vida. Conclusión: los progenitores se enfrentaron con obstáculos al tratar de encontrar ayuda sicológica dentro del cuidado de salud de primera instancia; los sicoterapeutas con una perspectiva familiar integral y aquellos que podían oscilar entre fomentar la percepción y las intervenciones de apoyo fueron especialmente apreciados; se identificaron categorías de pacientes que se beneficiaron del fomento de la percepción y del apoyo, respectivamente.

Le développement émotionnel et social d'un enfant dépend du soutien optimal qu'offrent les parents. Beaucoup de parents avec une détresse périnatale font l'expérience de difficultés quant à la gestion du parentage et cherchent l'aide de professionnels au sein des soins de santé primaires. Un projet clinique a été lancé à Stockholm, en Suède, au sein duquel des psychothérapeutes psychodynamiques ont offert des consultations à court terme dans les Centres de Santé de l'Enfant. Cette étude a exploré de manière qualitative les expériences de détresse périnatale des parents et l'aide qu'ils ont reçue de la part des infirmières/infirmiers et des thérapeutes dans ce projet. Méthode: Treize parents ont passé un entretien, et leurs réponses ont été analysées au moyen d'une méthode herméneutique. Résultats : Trois thèmes principaux ont émergé, l'accès à l'aide psychologique et la détection de problèmes émotionnels, les expériences de thérapie au Centre de Santé de l'Enfant, et la technique des thérapeutes. Les parents ont aussi été regroupés en trois soi-disant Types Parfaits: les insécures, les parents en crise et les parents avec des problèmes psychologiques de longue haleine. Conclusion: Les parents ont fait l'expérience d'obstacles dans l'accès au soin psychologique au sein des soins de santé primaires. Les psychothérapeutes ayant une perspective familiale holistique et ceux qui sont arrivés à osciller entre une promotion de perspicacité et des interventions de soutien ont été généralement appréciés. Les catégories de patients qui ont respectivement bénéficié de perspicacité et de soutien ont été identifiées.

The benefits of collaboration: the Nordic Arthroplasty Register Association.

The Nordic Arthroplasty Register Association (NARA) was established in 2007 by arthroplasty register representatives from Sweden, Norway and Denmark with the overall aim to improve the quality of research and thereby enhance the possibility for quality improvement with arthroplasty surgery. Finland joined the NARA collaboration in 2010.NARA minimal hip, knee and shoulder datasets were created with variables that all countries can deliver. They are dynamic datasets, currently with 25 variables for hip arthroplasty, 20 for knee arthroplasty and 20 for shoulder arthroplasty.NARA has published statistical guidelines for the analysis of arthroplasty register data. The association is continuously working on the improvement of statistical methods and the application of new ones.There are 31 published peer-reviewed papers based on the NARA databases and 20 ongoing projects in different phases. Several NARA publications have significantly affected clinical practice. For example, metal-on-metal total hip arthroplasty and resurfacing arthroplasty have been abandoned due to increased revision risk based on i.a. NARA reports. Further, the use of uncemented total hip arthroplasty in elderly patients has decreased significantly, especially in Finland, based on the NARA data.The NARA collaboration has been successful because the countries were able to agree on a common dataset and variable definitions. The collaboration was also successful because the group was able to initiate a number of research projects and provide answers to clinically relevant questions. A number of specific goals, set up in 2007, have been achieved and new one has emerged in the process. Cite this article: EFORT Open Rev 2019;4 DOI: 10.1302/2058-5241.4.180058.

Defensive patterns in reflective group supervisions at Child Health Centres.

Reflective group supervision with infant healthcare workers has been described in several publications. It aims to enhance their ability to help distressed families, and to comprehend and relieve themselves of the distress that they encounter in such work. The ultimate aim has been formulated as an effort at increasing the professional's reflective function. The present article adds to the literature by applying an ego-psychological perspective on the group process and investigating defensive patterns in such supervisions. This approach includes a critical discussion of the place of the reflective function concept in psychoanalytic metapsychology. The article also suggests a Bionian perspective to account for skewed communicative patterns in groups, so-called basic assumptions. Some technical recommendations are provided on the frame in group supervision. They aim to disarm such defenses and facilitate the group participants' possibilities of understanding and thus helping their colleague's problematic relationship with the family. To illustrate the discussion, and to help readers form an image of the supervision process, brief detailed accounts of such work are submitted.

La supervisión con reflexión en grupo con trabajadores dedicados al cuidado de salud de infantes ha sido descrita en varias publicaciones. La misma busca mejorar su habilidad para ayudar a familias angustiadas, así como comprender y relevarse a sí mismos de la angustia que ellos encuentran en tal ocupación. El objetivo final ha sido formulado como un esfuerzo para incrementar la función de reflexión del profesional. El presente ensayo contribuye a los estudios impresos por medio de aplicar una perspectiva ego-sicológica sobre el proceso de grupo e investigar patrones de defensa en tales supervisiones. Este acercamiento incluye una discusión crítica del lugar que ocupa el concepto de función de reflexión dentro de la metasicología sicoanalítica. Este artículo también sugiere una perspectiva basada en los estudios de Bion para explicar distorsionados patrones comunicativos de grupos, conocidos como suposiciones básicas. Se aportan algunas recomendaciones técnicas acerca del marco en la supervisión en grupo. Su objetivo es desarmar tales defensas y facilitar las posibilidades de comprensión de los participantes en el grupo y, por consiguiente, ayudar a sus colegas en las relaciones problemáticas con la familia. Para ilustrar la discusión, y para ayudar a los lectores a formarse una imagen del proceso de supervisión, se presentan breves recuentos detallados de tal tipo de trabajo.

La supervision réfléchie en groupe avec les professionnels de la santé mentale du nourrisson a été décrite dans plusieurs publications. Elle se donne pour but d'améliorer leur capacité à aider des familles dans la détresse ainsi qu'à comprendre et à les soulager de la détresse qu'ils ou elles rencontrent dans un tel travail. Le but ultime a été formulé comme étant un effort d'augmenter la fonction de réflexion du professionnel. Cet article s'ajoute aux recherches actuelles en appliquant une perspective égo-psychologique au processus de groupe et en recherchant les patterns défensifs dans de telles supervisions. Cette approche comprend une discussion critique de la place du concept de la fonction de réflexion dans la métapsychologie psychanalytique. Cette étude suggère également une perspective Bionienne afin de représenter les patterns communicatifs biaisés en groupes, ce que l'on appelle les postulats de base. Certaines recommandations techniques sont offertes sur la structure dans la supervision de groupe. Elles ont pour but de désarmer de telles défenses et de faciliter les possibilités de compréhension des participants ou participantes au groupe et donc d'aider la relation problématique de leur collègue avec la famille. Pour illustrer la discussion et afin d'aider les lecteurs à se former une image du processus de supervision, des récits détaillés brefs d'un tel travail sont présentés.

The short-term survival of total stemless shoulder arthroplasty for osteoarthritis is comparable to that of total stemmed shoulder arthroplasty: a Nordic Arthroplasty Register Association study.

BACKGROUND: The purpose of this study was to compare the short-term survival rate of total stemless, metaphyseal fixated, shoulder arthroplasty with that of total stemmed shoulder arthroplasty in the treatment of osteoarthritis. METHODS: Data were collected by the national arthroplasty registries in Denmark, Finland, Norway, and Sweden and merged into 1 dataset under the umbrella of the Nordic Arthroplasty Register Association. For the present study, we included all patients with osteoarthritis treated with either stemless (n = 761) or stemmed (n = 4398) shoulder arthroplasty from 2011 to 2016. RESULTS: A total of 21 (2.8%) stemless and 116 (2.6%) stemmed shoulder arthroplasties were revised. The 6-year unadjusted cumulative survival rates were 0.953 for stemless shoulder arthroplasty and 0.958 for stemmed shoulder arthroplasty, P = .77. The most common indication for revision of both arthroplasty types was infection. Five (0.7%) stemless and 16 (0.4%) stemmed shoulder arthroplasties were revised because of loosening of either the glenoid or the humeral component. In the multivariate cox regression model, which included age, category, gender, year of surgery, previous surgery, and arthroplasty type, the hazard ratio (HR) for revision of the stemless shoulder arthroplasty was 1.00 (95% confidence interval [CI], 0.63-1.61), P = .99, with the stemmed shoulder arthroplasty as reference. Male gender (HR = 1.50 [95% CI, 1.06-2.13], P = .02) and previous surgery (HR = 2.70 [95% CI, 1.82-4.01], P < .001) were associated with increased risk of revision. CONCLUSION: The short-term survival of total stemless shoulder arthroplasty appears comparable with total stemmed shoulder arthroplasty, but longer observation time is needed to confirm whether they continue to perform equally.

Core Set of Radiographic Parameters for Shoulder Arthroplasty Monitoring: Criteria Defined by an International Delphi Consensus Process.

Some unfavorable local events following shoulder arthroplasty occur without the patient experiencing symptoms and yet may be detected on diagnostic imaging, thereby serving as indicators of complications that may require revision. Our aim was to create a standardized protocol for an image-based monitoring process for assessing patients who are asymptomatic following shoulder arthroplasty. METHODS: A Delphi exercise was implemented with the participation of an international panel of experienced shoulder surgeons. On the basis of expert opinion from a core steering group, an initial list of imaging parameters for shoulder arthroplasty monitoring of asymptomatic patients was developed and reviewed by panel members. The most appropriate imaging modality was identified. Between each survey, all feedback was considered in order to revise the proposed core set with its definitions and specifications. Consensus was reached upon a two-thirds agreement. RESULTS: Three online surveys were administered, with 98 surgeons responding to the first and/or the second survey. The response rate for the final survey was 74%. Final parameter definitions were organized in 7 categories (implant migration, radiolucency around implant and implant loosening, signs of shoulder displacement, bone resorption and formation, wear of implant articular surfaces, fractures around the implant, and implant breakage and disassembly) and approved with 85% to 100% agreement. Seventy-eight percent of the panel members agreed on a minimum radiographic imaging schedule: standard anteroposterior and axial (alternatively, Y) views made within 6 weeks after implantation and between 3 and 6 months as well as at 12 months post-surgery. CONCLUSIONS: Our work presents a monitoring tool developed with international consensus for the assessment of asymptomatic patients after shoulder arthroplasty and including a structured core set of radiographic parameters. Clinical application and scientific evaluation of the monitoring process are needed. CLINICAL RELEVANCE: This represents a major step toward the standardization of shoulder arthroplasty radiographic monitoring for routine quality controls and research investigations.

A hermeneutic study of integrating psychotherapist competence in postnatal child health care: nurses' perspectives.

BACKGROUND: There is a considerable prevalence of and an increasing attention to emotional problems in families with infants. Yet, knowledge is scant of how to create efficient and accessible mental health services for this population. The study qualitatively explored public health nurses' conceptions of a clinical project, in which psychotherapists provided short-term consultations and supervisions for nurses at Child Health Centres in Stockholm. METHODS: In-depth interviews with fifteen nurses. The guideline of the interviews contained open-ended questions that were analysed applying a hermeneutical approach. RESULTS: Four main themes crystallized; The nurses' conceptions of their psychosocial work, Trespassing on another professional role, Interprofessional collaboration at the Child Health Centre, and The nurses' conceptions of the psychotherapist's function. In a second step, an analysis that clustered the nurses' attitudes towards handling mental health problems yielded one last theme with three "Ideal types"; nurses who expressed "I don't want to", "I want to but I cannot", and "I want to and I can" (take care of families' emotional problems at the CHC). CONCLUSION: The nurses appreciated the easy referral and accessibility to the psychotherapists, and the possibilities of learning more about perinatal mental illness and parent-infant interactions. For a successful cooperation with the nurses, the therapist should be a team member, be transparent about his/her work, and give feedback about cases in treatment. The study also shows how the organization needs to clarify its guidelines and competence to improve psychological child health care. The paper suggests improvements for an integrated perinatal mental health care.
