Non-surgical treatment for adult spinal deformity: results of an intensive combined physical and psychological programme for patients with adult spinal deformity and chronic low back pain—a treatment-based cohort study

Objectives

No evidence-based treatment exists for adult spinal deformity (ASD) patients with chronic low back pain (CLBP). Aim of this study: evaluate a combined physical and psychological programme (CPPP) for ASD patients with CLBP and to compare this with a non-ASD-cohort with CLBP.

Methods

Data were extracted from the database of CLBP-patients for whom surgery is not an option and completed CPPP. Two cohorts were selected: an ASD-cohort (n = 80) based on a Cobb angle of > 10° and a consecutive age- and gender-matched non-ASD-cohort (n = 240). Primary outcome: functional status (Oswestry Disability Index; ODI). Secondary outcomes: pain intensity, self-efficacy and quality of life. Assessments: pre and post treatment, one-month and one-year follow-up (FU). Clinical relevance: minimal important clinical change (MCIC; ODI 10 points), patient acceptable symptom state (PASS; ODI ≤ 22).

Results

Demographics ASD-cohort: 79% female, mean age 50.9 (± 14.1) years, mean CLBP duration 15.5 (± 12.5) years, mean Cobb angle 21.4 (± 9.4)°. Non-ASD-cohort: not significantly different. Both cohorts improved in functional status (F[1,318] = 142.982, p < .001; r = 0.31). The ASD-cohort improved from mean ODI 39.5(± 12.0) at baseline to mean ODI 31.8(± 16.5) at one-year FU. Clinical relevance: 51% of the ASD patients reached MCIC and 33% reached a PASS. An interaction effect is shown between time and both cohorts (F[1,318] = 8.2, p = .004; r = 0.03); however, not clinically relevant. All secondary outcomes: improvement at one-year FU.

Conclusion

This is the first study showing beneficial outcomes of a non-surgical treatment in selected ASD patients with longstanding CLBP. Improvement is shown in functional status, and appeared equivalent to the non-ASD cohort.

Unraveling postoperative alterations after mitral valve replacement with three-dimensional printing

Mitral valve (MV) surgery is the second most performed valve operation in Europe. MV pathology is associated with atrial fibrillation, and, therefore, frequently combined with rhythm surgery and left atrial appendage exclusion (LAAE). Currently, no guidelines exist regarding the follow up after LAAE postoperative. Postoperative imaging with computed tomography (CT), in the absence of complaints, will inherently reveal unsuspected cardiac and noncardiac findings with potential clinical significance. However, poststernotomy alterations are nonspecific and often overlap with normal postoperative changes and could, therefore, not directly be recognized. Virtual three-dimensional (3D) CT reconstructions can help us to visualize 2D structures, especially in areas where structures overlap like coronary arteries or when devices (atrial clip, MV prosthesis) cause scattering artifacts. Advanced imaging reconstructions and 3D printing can enhance understanding of the cardiac anatomy in the postoperative phase and help us to determine follow-up strategies.     

COVID-19 in solid organ transplant recipients: a single-center experience

Solid organ transplant (SOT) recipients may be at risk for severe COVID-19. Data on the clinical course of COVID-19 in immunosuppressed patients are limited, and the effective treatment strategy for these patients is unknown. We describe our institutional experience with COVID-19 in SOT. Demographic, clinical, and treatment data were extracted from the electronic patient files. A total of 23 SOT transplant recipients suffering from COVID-19 were identified (n = 3 heart; n = 15 kidney; n = 1 kidney-after-heart; n = 3 lung, and n = 1 liver transplant recipient). The presenting symptoms were similar to nonimmunocompromised patients. Eighty-three percent (19/23) of the patients required hospitalization, but only two of these were transferred to the intensive care unit. Five patients died from COVID-19; all had high Clinical Frailty Scores. In four of these patients, mechanical ventilation was deemed futile. In 57% of patients, the immunosuppressive therapy was not changed and only three patients were treated with chloroquine. Most patients recovered without experimental antiviral therapy. Modification of the immunosuppressive regimen alone could be a therapeutic option for SOT recipients suffering from moderate to severe COVID-19. Pre-existent frailty is associated with death from COVID-19.     

Usability of Ventricular Assist Devices in Daily Experience: A Multicenter Study

In daily life, the safe, intuitive use of ventricular assist devices (VADs) and especially their peripheral components is not only a question of life quality, but also sometimes crucial for survival. To investigate the advantages and disadvantages of different systems and to get patient feedback on preferred features, a multicenter study was initiated. Based on previous single‐center studies, a questionnaire was developed to ascertain patients' experiences, difficulties with, and desires concerning use of the system. This questionnaire was provided both to ongoing patients and to new VAD patients after a minimum hospital discharge time of 6 weeks, at a regular checkup. Additionally, the patients completed a standardized questionnaire on life quality (Kansas City Cardiomyopathy Questionnaire). The centers that contributed to this study were Bad Oeynhausen, Berlin, Hannover, and Vienna. Three hundred fifty‐two completed questionnaires on eight different pump types were obtained. An important result is that 42% of those questioned dropped their controller bag at least once. Depending on the device, between 2 and 55% disconnected it unintentionally. Confidence in safe use of the system decreased significantly with age, from 80% at age 20–30 years to 33% at 70–80 years. In devices with an LCD display, 94% considered the readability sufficient. Ninety‐four percent considered the training adequate. Between 22 and 88% of the patients called the emergency telephone hotline, depending on the device, and 23–46% depending on the center. This first multicenter study on VAD usability reveals considerable differences among devices and centers. The comparative assessment aims to help optimize device design, patient management, and training.     

Rash Impulsiveness and Reward Sensitivity as predictors of treatment outcome in male substance dependent patients

Recent theories hypothesize that the impulsivity observed in addictive behaviors is a two-factor construct, consisting of Rash Impulsiveness and Reward Sensitivity. There is some evidence for this distinction, but it is unknown what the clinical relevance of this distinction is. The present study examines the predictive value of the two-factor model regarding drop-out from treatment and relapse into substance use in a clinical population of male substance dependent patients. Both behavioral and self-report measures of Rash Impulsiveness and Reward Sensitivity were measured during treatment while substance use relapse was measured after 90 days. Results indicate that treatment drop-out could be predicted by a behavioral index of Reward Sensitivity (Card Playing Task); self-reported Rash Impulsiveness only approached significance as predictor drop-out. In contrast, relapse could not be predicted in the present study. These findings might have implications for the early identification and treatment of patients at risk of treatment drop-out.     

Trends of Stroke Incidence and 28-Day All-Cause Mortality after a Stroke in Malaysia: A Linkage of National Data Sources

Background:Data on nationwide trends for stroke metrics are crucial to understand the extent of the disease burden to a country’s health system. Yet, this information remains scarce in low- and middle-income countries.Objectives:This study investigated trends of stroke incidence and 28-day all-cause mortality after a stroke from 2008 to 2016 in Malaysia, through linkage across national data sources.Methods:Hospital admissions with a principal diagnosis of stroke or transient ischemic attack were included. Cases with first stroke were identified through linkage of hospital admission registers where age and sex-standardized trends of stroke incidence and its subtypes were calculated. By linking hospital registers to the National Death Register, the 28-day all-cause mortality rates after a stroke were estimated. Mann-Kendall’s test was used for trend evaluation.Results:From 243,765 records, the trend of stroke incidence showed an increase of 4.9% in men and a drop of 3.8% among women. Incidences were higher in men, at 99.1 per 100,000 population in 2008 and 103.9 per 100,000 in 2016 than women (80.3 per 100,000 in 2008 and 77.2 per 100,000 in 2016). There was a substantial increase in stroke incidence among those below 65 years old, with the largest increase of 53.3% in men aged between 35–39 years and 50.4% in women of similar age group. The trend for 28-day all-cause mortality showed a decline for men at –13.1% and women, –10.6%. Women had higher mortality from stroke (22.0% in 2008 and 19.7% in 2016) than men (19.4% in 2008 to 17.2% in 2016).Conclusion:This first empirical study on stroke trends in Malaysia revealed a worrying increase in stroke incidence among the younger population. Despite a declining trend, mortality rates remained moderately high especially in women. Comprehensive strategies to strengthen the prevention and management of stroke care are warranted.
