The TOR concept (training, operation, and rehabilitation) applied to a cohort of postpartum women with training-resistant symptomatic rectus diastasis: evaluation 1 year after surgery.

BACKGROUND: Rectus diastasis is a common sequela of pregnancy and is associated with functional disabilities such as back pain, abdominal core instability, abdominal muscle weakness, urinary incontinence, and psychological issues such as a negative body image. The aim of this study was to evaluate the effect of the TOR concept (training, operation, and rehabilitation), a novel concept for treating abdominal wall insufficiency combined with rectus diastasis, after pregnancy. TOR consists of preoperative evaluation of symptoms and custom-designed abdominal core training, tailored rectus diastasis repair, and individual progressive postoperative rehabilitation. METHODS: A consecutive series of women diagnosed with rectus diastasis and core dysfunction resistant to training, underwent plication of the linea alba between 2018 and 2020. After surgery, all patients participated in an individually designed rehabilitation programme over a 4-month interval. Physical function was recorded before surgery and 1 year after surgery using the disability rating index questionnaire. Symptoms associated with core instability were recorded before and 1 year after surgery. Quality of life was assessed using the SF-36. The abdominal wall anatomy was assessed with ultrasound before and 1 year after surgery. RESULTS: Seventy-one women were included and all attended 1-year follow-up. Response rate was 81.7 per cent (58) for the disability rating index, and 59.2 per cent (42) for SF-36. Self-reported physical function (disability rating index) improved in 54 of 58 patients (93.1 per cent), with a median score reduction of 91.3 per cent. Core instability symptoms decreased significantly. All SF-36 subscales improved significantly compared with preoperative scores, reaching levels similar to or higher than the normative Swedish female population. No recurrence of rectus diastasis was seen at the 1-year follow-up. CONCLUSIONS: Surgical reconstruction within the TOR concept resulted in significant improvements in physical function and quality of life as well as a significant decrease in symptoms of core instability.

Association Between Inter-Recti Distance and Impaired Abdominal Core Function in Post-Partum Women With Diastasis Recti Abdominis.

Background and Aim: The definition and management of Diastasis Recti Abdominis (DRA) is under debate. This study aimed to understand the correlation between the post-partum inter-recti distance (IRD) and functional impairments associated with core instability, with the hypothesis that IRD could serve as a proxy for core instability symptoms and constitute a tool in decision-making for DRA treatment. Material and Methods: A cohort of post-partum women with abdominal core instability symptoms combined with DRA were studied. The size of IRD was measured with ultrasonography and cross-sectionally analysed against functional impairments registered with the self-report Disability Rating Index (DRI), which grades the ability to perform 12 different daily activities. Results: A total of 224 women were included in the study. In univariable analysis, IRD was associated with impairment of the activities running (p = 0.007), heavy work (p = 0.036) and exercise/sports (p = 0.047), but not with dressing, walking, sitting for long periods, standing bent over a sink, carrying a suitcase, making a bed, light manual labour or heavy lifting. No significant correlations were seen in the multivariable analysis when adjustments were made for BMI and parity. Conclusion: IRD and post-partum functional impairments had no significant correlation in multivariable analysis. The post-partum core instability condition is complex and probably associated with more factors than solely the IRD. The IRD alone does not seem to be a sufficient proxy for decision-making regarding optimal treatment. A more complete instrument to assess the post-partum abdominal core is warranted.

Evaluation of functional outcomes following rectus diastasis repair-an up-to-date literature review.

INTRODUCTION: Over the last decade rectus diastasis has gained attention as a condition that may benefit from surgery. Numerous surgical techniques have been presented but scientifically proper studies reporting functional outcome are few and evidence is incomplete. The aim of this up-to-date review is to analyse the outcomes of rectus diastasis repair in recently published papers, focusing on functional changes following surgery. METHOD: A comprehensive search in PubMed and Web of Science was performed. Suitable papers were selected using titles and abstracts with terms suggesting surgical treatment of rectus diastasis. All abstracts were scrutinised, and irrelevant studies excluded in four stages. Reports providing original data, including outcome assessment following surgery, were included. RESULT: Ten papers with a total of 780 patients were found to fulfil the search criteria. Study design, surgical procedure, follow-up time, functional outcome and assessment instruments were compiled. All included studies reported improvements in a variety of functional aspects regardless of surgical method. The outcomes assessed include core stability, back pain, abdominal pain, posture, urinary incontinence, abdominal muscle strength and quality of life. CONCLUSION: The results of this review show that surgical repair of rectus diastasis is a safe and effective treatment that improves functional disability. However, the absence of standardized instruments for assessing outcome makes it impossible to compare studies. Since indications for surgery are relative and related to core function, valid instruments for assessing indication and outcome are needed to ensure benefit of the procedure.

Cohort study of the effect of surgical repair of symptomatic diastasis recti abdominis on abdominal trunk function and quality of life.

Background: During pregnancy, women are at risk of developing persistent symptomatic diastasis recti abdominis (DRA), which may have a detrimental effect on their physical function and quality of life (QoL). The aim of this prospective cohort study was to determine the effect of surgical repair of DRA on abdominal trunk function, urinary incontinence and QoL in postpartum women with trunk instability symptoms resistant to training. Methods: Postpartum women with diagnosed DRA and training-resistant symptoms underwent double-row plication of the linea alba. Abdominal trunk function was evaluated as the primary endpoint using a multimodal examination tool, the Abdominal Trunk Function Protocol. Recurrence was assessed by CT, urinary incontinence was evaluated using the Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7), and QoL was assessed with the Short Form 36 (SF-36®) questionnaire. All subjects were examined before and 1 year after surgery. Results: Sixty women were recruited. There was no DRA recurrence at the 1-year follow-up. Self-reported abdominal trunk function had improved in 98 per cent of patients, with a mean score improvement of 79·1 per cent. In the physiological tests monitored by a physiotherapist, 76 per cent performed better and endured exercise tests longer than before surgery. All SF-36® subscales improved significantly compared with preoperative scores and reached levels similar to, or higher than, the normative Swedish female population. For the UDI-6 and IIQ-7, 47 and 37 per cent respectively reported fewer symptoms at follow-up than before surgery, and 13 and 8 per cent respectively reported more symptoms. Conclusion: In this series of postpartum women presenting with DRA and symptoms of trunk instability resistant to training, surgical reconstruction resulted in a significant improvement in abdominal trunk function, urinary incontinence and QoL.

Antecedentes: Durante el embarazo, las mujeres tienen el riesgo de desarrollar una diástasis rectoabdominal persistente y sintomática (diastasis rectoabdominis, DRA) que puede tener un efecto perjudicial en su función física y en la calidad de vida (quality of life, QoL). El objetivo de este estudio de cohortes prospectivo fue determinar el efecto de reparación quirúrgica de la DRA en la función de la musculatura de la pared abdominal, la incontinencia urinaria y la QoL en mujeres con síntomas postparto de inestabilidad de la musculatura abdominal resistentes al entrenamiento. Métodos: Sesenta mujeres diagnosticadas en el postparto de DRA y con síntomas resistentes al entrenamiento se sometieron a una plicatura de doble capa de la línea alba. El objetivo primario fue evaluar la función de la musculatura de la pared abdominal mediante una herramienta de examen multimodal, el protocolo de la función de la pared abdominal (abdominal trunk function protocol, ATFP). La recidiva se evaluó mediante tomografía computarizada, la incontinencia urinaria utilizando los cuestionarios UDI­6 y IIQ­7 y la calidad de vida con el cuestionario SF­36. Todas las participantes fueron examinadas antes de la cirugía y un año después de la misma. Resultados: Tras un año de seguimiento, no hubo recidiva de la DRA. Según informaron las pacientes, la función de la musculatura abdominal había mejorado en el 98,2% de los casos, con una mejoría en la puntuación media del 79,1%. En las pruebas fisiológicas controladas por un fisioterapeuta, el 76,0% presentó mejoría y aumentó la duración en las pruebas de resistencia en comparación con antes de la cirugía. Todas las subescalas del SF­36 mejoraron significativamente en comparación con las puntuaciones preoperatorias y alcanzaron niveles similares o superiores a los de la población femenina sueca normal. Para el UDI­6 y el IIQ­7, el 46,7% y el 36,7% respectivamente, manifestaron menos síntomas en el seguimiento que antes de la cirugía, mientras que el 13,3% y el 8,3% respectivamente, reportaron más síntomas. Conclusión: En esta serie de mujeres que presentan DRA en el posparto y síntomas de inestabilidad de la musculatura abdominal resistente al entrenamiento, la reconstrucción quirúrgica produjo una mejora significativa en la función de la musculatura abdominal, la incontinencia urinaria y la calidad de vida.

[Lung cancer screening with thoracic X­ray and CT : Current situation]. / Lungenkarzinomscreening mit Röntgenthorax oder CT : Aktuelle Datenlage.

CLINICAL/METHODICAL ISSUE: Attempts at the early detection of lung cancer using imaging methods began as far back as the 1950s. STANDARD RADIOLOGICAL METHODS: Several studies attempted to demonstrate a reduction of lung cancer mortality by chest radiography screening but all were unsuccessful. METHODICAL INNOVATIONS: Even the first small screening studies using computed tomography (CT) could not demonstrate a reduction in lung cancer-specific mortality until in 2011 the results of the largest randomized controlled low-dose CT screening study in the USA (NLST) were published. The NLST results could show a significant 20 % reduction of lung cancer mortality in elderly and heavy smokers using CT. PERFORMANCE: Confirmation of the NLST results are urgently needed so that the data of the largest European study (NELSON) are eagerly awaited. ACHIEVEMENTS: Pooled with the data from several smaller European studies these results will provide important information and evidence for the establishment of future CT screening programs in Europe. PRACTICAL RECOMMENDATIONS: Randomized controlled trials are the basis of evidence-based medicine; therefore, the positive results of the methodologically very good NLST study cannot be ignored, even if it is the only such study completed so far with highly convincing conclusions. The NLST results clearly demonstrate that positive effects for the health of the population can only be expected if the processes are clearly defined and the quality is assured.

Sex differences in the association between smoking and abdominal aortic aneurysm.

BACKGROUND: It is unclear whether recommendations about ultrasound screening programmes for abdominal aortic aneurysm (AAA) among men should be extended to include women who smoke. The aim was to examine sex-specific dose-response associations between AAA risk and smoking status, pack-years smoked and time since smoking cessation. METHODS: Women in the Swedish Mammography Cohort and men in the Cohort of Swedish Men were followed up from 1998 to 2011. AAA was identified through linkage of the cohorts to the Swedish Inpatient Register and the Swedish National Register for Vascular Surgery (Swedvasc), and not through general ultrasound screening. Associations were estimated with Cox proportional hazards models. RESULTS: The cohorts included 35 550 women and 42 596 men, aged 46-84 years. During follow-up, AAA was identified in 199 women and 958 men. The incidence of AAA per 100 000 person-years was 76 among men who never smoked and 136 among women who currently smoke. Regarding AAA risk, women were more sensitive to current smoking (Pinteraction = 0·002). Compared with never smokers, the hazard ratio (HR) for AAA in current smokers with more than 20 pack-years was 10·97 (95 per cent confidence interval 7·41 to 16·26) among women and 6·55 (5·36 to 7·99) among men. Following smoking cessation, women had a more rapid decline in excess risk (Pinteraction < 0·001). The risk was halved after 11 years (HR 0·51, 0·32 to 0·81) among women and after 23 years (HR 0·50, 0·42 to 0·60) among men. CONCLUSION: There were sex differences in the associations between smoking status and AAA risk. These data support further investigation of targeted AAA screening among women who smoke.

Obesity and abdominal aortic aneurysm.

BACKGROUND: The relationship between obesity and abdominal aortic aneurysm (AAA) is unclear. An observational cohort study was undertaken to examine the associations between waist circumference as a measure of abdominal adiposity, and between body mass index (BMI) as a measure of total adiposity, and risk of AAA. METHODS: Data were used from the population-based Swedish Mammography Cohort and the Cohort of Swedish Men, involving 63,655 men and women, aged 46-84 years. Between 1998 and 2009, 597 patients with incident AAA defined by relevant clinical events were identified by linkage to the Swedish Inpatient Register and the Swedish Vascular Registry. Cox proportional hazards models were used to estimate relative risks (RRs) with 95 per cent confidence intervals. RESULTS: In multivariable analysis, individuals with an increased waist circumference had a 30 per cent higher risk of AAA (RR 1·30, 95 per cent confidence interval 1·05 to 1·60) compared with those with a normal waist circumference. The risk of AAA increased by 15 per cent (RR 1·15, 1·05 to 1·26) per 5-cm increment of waist circumference up to the level 100 cm for men and 88 cm for women. There was no association between BMI and risk of AAA. CONCLUSION: Abdominal, but not total, adiposity was associated with an increased risk of incident AAA. A threshold was observed at a waist circumference of 100 cm for men and 88 cm for women.
