Experiences from the implementation of physical therapy via telehealth for individuals with Parkinson disease during the COVID-19 pandemic

PURPOSE

To (1) determine the characteristics and participation rate of adults with Parkinson disease (PD) in physical therapy (PT) delivered via telehealth, (2) identify the outcome measures and interventions implemented, (3) determine the safety of and (4) patient and therapist satisfaction with PT via telehealth in a clinic specializing in the care of people with PD during the coronavirus pandemic.

MATERIALS & METHODS

A retrospective analysis of PT services via telehealth was conducted. Participating patients completed a satisfaction survey. Physical therapists (PTs) who delivered this care were interviewed. Three coders conducted thematic analysis of interviews. Descriptive statistics described the participation rate, demographics, outcome measures, interventions, and safety.

RESULTS

There was a 71.4% participation rate. Participants (n = 55) were white (96%), non-Hispanic (100%), older adult (mean = 69.5 years (8.3)) males (65.5%). Non-participants (n = 22) had similar demographics. Therapists selected patient-reported measures more often than performance-based measures. Therapeutic exercise was the most common intervention. All patients (80% response rate) reported satisfaction with their experience. PTs reported the home enhanced specificity of training but impeded evaluation. Therapists endorsed a hybrid model for future practice.

CONCLUSIONS

Patients reported satisfaction with PT via telehealth during the pandemic. A hybrid model may support optimal delivery of PT.IMPLICATIONS FOR REHABILITATIONPhysical therapy via telehealth for patients with Parkinson disease was acceptable to patients and physical therapists in our study.Physical therapy via telehealth was safe for people with Parkinson disease in our study, although availability and benefits may not be reaching all populations equitably.Both physical therapists and patients endorse a hybrid model of care (a combination of in-person and remote assessment and treatment) to profit from the strengths of in-person and virtual formats while minimizing barriers to access.

Differential associations of conduct disorder, callous-unemotional traits and irritability with outcome expectations and values regarding the consequences of aggression

BACKGROUND

Previous work has examined the association of aggression levels and callous-unemotional traits with outcome expectations and values regarding the consequences of aggression. Less work has examined the outcome expectations and values regarding the consequences of aggression of adolescents with Conduct Disorder (CD). Also, no studies have examined links between irritability (a second socio-affective trait associated with CD) and these social cognitive processes despite the core function of anger in retaliatory aggression and establishing dominance.

METHOD

The current study, investigating these issues, involved 193 adolescents (typically developing [TD; N = 106], 87 cases with CD [N = 87]). Participants completed an adaptation of the Outcomes Expectations and Values Questionnaire and were assessed for CU traits and irritability via the Inventory of Callous-Unemotional traits and the Affective Reactivity Index.

RESULTS

While CD was associated with atypical outcome expectations this was not seen within statistical models including CU traits and irritability. CU traits were associated with decreased expectation that aggression would result in feelings of remorse and victim suffering, as well as decreased concern that aggressive acts would result in punishment and victim suffering. Irritability was associated with increased expectations and concern that aggression would result in dominance and forced respect.

CONCLUSIONS

The results suggest that CU traits and irritability, often present in youth with CD, are associated with different forms of maladaptive outcome expectations and values regarding the consequences of aggression. This suggests that the atypical social cognitive processes underlying aggressive behavior among youth exhibiting CU traits may differ from those exhibiting problems regulating anger.

[Telemedicine in stroke-pertinent to stroke care in Germany]

BACKGROUND AND OBJECTIVE

Telemedical stroke networks improve stroke care and provide access to time-dependent acute stroke treatment in predominantly rural regions. The aim is a presentation of data on its utility and regional distribution.

METHODS

The working group on telemedical stroke care of the German Stroke Society performed a survey study among all telestroke networks.

RESULTS

Currently, 22 telemedical stroke networks including 43 centers (per network: median 1.5, interquartile range, IQR, 1-3) as well as 225 cooperating hospitals (per network: median 9, IQR 4-17) operate in Germany and contribute to acute stroke care delivery to 48 million people. In 2018, 38,211 teleconsultations (per network: median 1340, IQR 319-2758) were performed. The thrombolysis rate was 14.1% (95% confidence interval 13.6-14.7%) and transfer for thrombectomy was initiated in 7.9% (95% confidence interval 7.5-8.4%) of ischemic stroke patients. Financial reimbursement differs regionally with compensation for telemedical stroke care in only three federal states.

CONCLUSION

Telemedical stroke care is utilized in about 1 out of 10 stroke patients in Germany. Telemedical stroke networks achieve similar rates of thrombolysis and transfer for thrombectomy compared with neurological stroke units and contribute to stroke care in rural regions. Standardization of network structures, financial assurance and uniform quality measurements may further strengthen the importance of telestroke networks in the future.

Impact of the coronavirus disease 2019 pandemic on stroke teleconsultations in Germany in the first half of 2020

Background and purpose

The effects of the coronavirus disease 2019 (COVID‐19) pandemic on telemedical care have not been described on a national level. Thus, we investigated the medical stroke treatment situation before, during, and after the first lockdown in Germany.

Methods

In this nationwide, multicenter study, data from 14 telemedical networks including 31 network centers and 155 spoke hospitals covering large parts of Germany were analyzed regarding patients' characteristics, stroke type/severity, and acute stroke treatment. A survey focusing on potential shortcomings of in‐hospital and (telemedical) stroke care during the pandemic was conducted.

Results

Between January 2018 and June 2020, 67,033 telemedical consultations and 38,895 telemedical stroke consultations were conducted. A significant decline of telemedical (p < 0.001) and telemedical stroke consultations (p < 0.001) during the lockdown in March/April 2020 and a reciprocal increase after relaxation of COVID‐19 measures in May/June 2020 were observed. Compared to 2018–2019, neither stroke patients' age (p = 0.38), gender (p = 0.44), nor severity of ischemic stroke (p = 0.32) differed in March/April 2020. Whereas the proportion of ischemic stroke patients for whom endovascular treatment (14.3% vs. 14.6%; p = 0.85) was recommended remained stable, there was a nonsignificant trend toward a lower proportion of recommendation of intravenous thrombolysis during the lockdown (19.0% vs. 22.1%; p = 0.052). Despite the majority of participating network centers treating patients with COVID‐19, there were no relevant shortcomings reported regarding in‐hospital stroke treatment or telemedical stroke care.

Conclusions

Telemedical stroke care in Germany was able to provide full service despite the COVID‐19 pandemic, but telemedical consultations declined abruptly during the lockdown period and normalized after relaxation of COVID‐19 measures in Germany.

Detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in vaginal swabs of women with acute SARS-CoV-2 infection: a prospective study

Objective

To determine whether severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) is present in the vaginal secretions of both reproductive‐aged and postmenopausal women during acute SARS‐CoV‐2 infection.

Design

Prospective study.

Setting

A single tertiary, university‐affiliated medical centre in Israel. Time period, 1 June 2020 through to 31 July 2020.

Population

Women who were hospitalised in a single tertiary medical centre, who were diagnosed with acute SARS‐CoV‐2 infection by a nasopharyngeal RT‐PCR test.

Methods

Women were diagnosed with acute SARS‐CoV‐2 infection by a nasopharyngeal RT‐PCR test. Vaginal RT‐PCR swabs were obtained from all study participants after a proper cleansing of the perineum.

Main outcome measures

Detection of SARS‐CoV‐2 in vaginal RT‐PCR swabs.

Results

Vaginal and nasopharyngeal swabs were obtained from 35 women, aged 21–93 years. Twenty‐one women (60%) were in their reproductive years, of whom, five were in their third trimester of pregnancy. Most of the participants (57%) were healthy without any underlying medical conditions. Of the 35 patients sampled, 2 (5.7%) had a positive vaginal RT‐PCR for SARS‐CoV‐2, one was premenopausal and the other was a postmenopausal woman. Both women had mild disease.

Conclusion

Our findings contradict most previous reports, which did not detect the presence of viral colonisation in the vagina. Although passage through the birth canal exposes neonates to the vaginal polymicrobial flora, an acquisition of pathogens does not necessarily mandate neonatal infection or clinical disease. Nevertheless, when delivering the infant of a woman with acute SARS‐CoV‐2 infection, a clinician should consider the possibility of vaginal colonisation, even if it is uncommon.

Tweetable abstract

Reduction of Carnitine Content by Inhibition of Its Biosynthesis Results in Protection of Isolated Guinea Pig Hearts against Hypoxic Damage

Background

3-(2,2,2-trimethylhydrazinium) propionate (THP or mildronate) is an inhibitor of carnitine biosynthesis. This study was carried out to determine whether feeding of guinea pigs with THP results in decreased myocardial-free carnitine content and, as a result, attenuates hypoxic damage in isolated and paced work-performing hearts.

Methods and Results

Guinea pigs were administered either distilled water or 100 mg THP/kg/day orally for 10 days. The treatment resulted in about a 50% decline in myocardial-free carnitine content, from 11.1 ± 0.2 (n = 5) to 5.6 ± 0.2 (n = 5) μM/g dry weight of the heart. The left ventricular contractile function of the hearts was measured during normoxic perfusion (PO2= 590 mmHg), hypoxic perfusion (PO2= 149 mmHg), and reperfusion (PO2= 590 mmHg). In both untreated and THP-treated groups, the rate of development of intraventricular pressure (+dP/dt) under normoxic perfusion was similar; however, +dP/dt declined to about 10% of the initial rate within 20 minutes of hypoxic perfusion. In the THP-treated group of hearts, the initial decline was slower than that of the untreated animal hearts. After 20 minutes of normoxic reperfusion following 60 minutes of hypoxic perfusion, the recovery of +dP/dt and -dP/dt was greater in the THP-treated group than in the untreated group. The elevation of end-diastolic pressure during hypoxia was completely reversed by normoxic reperfusion of the THP-treated group but not in the untreated group. Mitochondria isolated from hearts from the THP-treated group after normoxic reperfusion following hypoxic perfusion exhibited better respiratory function than those from untreated hearts.

Conclusion

The data suggest that feeding guinea pigs with THP results in reduced myocardial-free carnitine content and attenuation of hypoxic and reperfusion injury in isolated hearts.

Functional MR Mapping of Activated Cortical Areas

Magnetic resonance imaging (MRI) has recently been demonstrated to be sensitive to changes in neuronal activity of cortical areas. We report our initial experiences with functional MR brain mapping at high spatial resolution using a conventional whole-body MR system. A total of 10 visual and motor cortex activation studies were carried out on 8 healthy volunteers. In each examination, a time course series of 15 strongly T2*-weighted FLASH images was measured from three adjacent slices. The image analysis revealed a subtle but highly significant signal increase in cortical layers of gray matter in primary and associative visual as well as sensorimotoric cortex regions during periods of excessive brain activity provoked by photic stimuli or motoric tasks, respectively. To correlate brain structure and brain function, the computed MR brain activation maps were directly superimposed on T1-weighted anatomic spin-echo images. With this advance into the area of functional neuroimaging, MRI is moving into an established domain of positron emission tomography (PET). We, therefore, discuss the advantages and limitations of the MR method in comparison to PET as far as this can be done at present.

Prevalence of and risk factors for low bone mineral density in untreated HIV infection: a substudy of the INSIGHT Strategic Timing of AntiRetroviral Treatment (START) trial

OBJECTIVES

HIV infection is associated with a higher prevalence of low bone mineral density (BMD) and fractures than that found in the general population. There are limited data in HIV-positive adults, naïve to antiretroviral therapy (ART), with which to estimate the relative contribution of untreated HIV infection to bone loss.

METHODS

The primary objective of the Strategic Timing of AntiRetroviral Treatment (START) Bone Mineral Density Substudy is to compare the effect of immediate versus deferred initial ART on bone. We evaluated traditional, demographic, HIV-related and immunological factors for their associations with baseline hip and lumbar spine BMD, measured by dual-energy X-ray absorptiometry, using multiple regression.

RESULTS

A total of 424 ART-naïve participants were enrolled at 33 sites on six continents; the mean age was 34 years [standard deviation (SD) 10.1 years], 79.0% were nonwhite, 26.0% were women, and 12.5% had a body mass index (BMI) < 20 kg/m(2) . Mean (SD) Z-scores were -0.41 (0.94) at the spine and -0.36 (0.88) for total hip; 1.9% had osteoporosis and 35.1% had low BMD (hip or spine T-score < -1.0). Factors independently associated with lower BMD at the hip and spine were female sex, Latino/Hispanic ethnicity, lower BMI and higher estimated glomerular filtration rate. Longer time since HIV diagnosis was associated with lower hip BMD. Current or nadir CD4 cell count and HIV viral load were not associated with BMD.

CONCLUSIONS

In this geographically and racially diverse population of ART-naïve adults with normal CD4 cell counts, low BMD was common, but osteoporosis was rare. Lower BMD was significantly associated with traditional risk factors but not with CD4 cell count or viral load.

Abstract P5-09-11: BP1, a homeoprotein, regulates estrogen receptor alpha and induces estrogen independence

Introduction: BP1 is a member of the homeobox gene family of transcription factors. Our recent studies have shown that BP1 may play a role in breast cancer cell survival, aggressiveness and metastasis. BP1 protein (pBP1) is expressed in 80% of invasive ductal breast tumors. Moreover, 100% of inflammatory breast tumors are BP1 positive. These data led us to define the mechanism of BP1-related tumorigenesis and aggressiveness in breast cancer.

Materials and Methods: MCF-7/O1, O2 and O4 cells overexpressing BP1 and control V1 and V2 cells were tested for growth in estrogen free media, malignant potential and invasiveness using cell viability assays, soft agar assays and matrigel assays, respectively. To determine the influence of BP1 overexpression on tumor characteristics, empty vector cells (V1) and overexpressor cells (O2 and O4) were injected into the fat pads of athymic nude mice. Mice were supplemented with estrogen pellets or were unsupplemented. Chromatin immunoprecipitation assays (ChIP) were used to validate the binding of pBP1 to ERa and EP300. The effects of BP1 expression on ERα and EP300 were investigated using immunoblotting and qRT-PCR. Effects of BP1 overexpression on tamoxifen sensitivity were measured using the MTT assay.

Results: Cells overexpressing BP1 showed higher viability (p&lt;0.05) when grown in the absence of serum, greater invasive potential (p&lt;0.05) and formed larger and more rapidly growing colonies (p&lt;0.0001) compared with cells containing the empty vector. Tumors were larger in mice receiving O1, O2 or O4 cells than in mice receiving V1 or V2 cells (p&lt;0.0001). There was also a positive correlation between BP1 mRNA levels and tumor size in patients (p = 0.01). 20% of mice injected with O2 or O4 developed tumors in the absence of estrogen, in contrast to control mice which did not develop tumors. Several mechanisms of estrogen independence related to BP1 were established: (1) an indirect mechanism, in which BP1 stabilizes ERα protein by transcriptional activation of p300, and (2) a direct mechanism, in which BP1 binds to the first intron of ERα and upregulates ERα RNA and protein expression. In addition, breast cancer anti-estrogen resistance 1 (BCAR1) RNA expression was higher in O2 as compared to V1 cells. Consistent with these findings, O2 cells exhibited increased proliferation when treated with tamoxifen, while V1 cells showed growth inhibition.

Conclusion: High BP1 levels can lead to estrogen independence in ER positive breast cancer cells and tumors in mice by at least two mechanisms, indirect and direct, and are associated with resistance to tamoxifen. These results suggest that BP1 may be an important therapeutic target in ER positive breast cancer.

Impact + resistance training improves bone health and body composition in prematurely menopausal breast cancer survivors: a randomized controlled trial

Our randomized controlled trial in prematurely menopausal breast cancer survivors showed that impact + resistance training prevented increases in percentage of body fat compared with controls and also improved BMD at the hip and prevented BMD loss at the spine among exercise-trained women who were menopausal for >1 year.

INTRODUCTION

Cancer treatment-related menopause worsens bone health and body composition in breast cancer survivors (BCS). We investigated whether impact + resistance training could improve bone mineral density (BMD), reduce bone turnover, build muscle, and decrease fat mass in BCS with premature menopause.

METHODS

We conducted a randomized controlled trial in 71 BCS (mean age, 46.5 years) within 5 years of treatment-related menopause. Women were randomly assigned to one of two groups: (1) impact + resistance training (prevent osteoporosis with impact + resistance (POWIR)) or (2) exercise placebo (FLEX) 3×/week for 1 year. Outcomes were hip and spine BMD (in grams per square centimeter) and body composition (percent body fat (%BF) and lean and fat mass (in kilograms)) by DXA and bone turnover markers (serum osteocalcin (in nanograms per milliliter) and urinary deoxypryrodinoline (in nanomoles per milliliter).

RESULTS

There were no significant group × time interactions for bone outcomes when using an intent-to-treat approach on the full sample. In analyses restricted to BCS who were menopausal for ≥1 year, POWIR increased BMD at the hip and slowed BMD loss at the spine compared with FLEX (femoral neck-POWIR, 0.004 ± 0.093 g/cm(2) vs. FLEX, -0.010 ± 0.089 g/cm(2); p < 0.01; spine-POWIR, -0.003 ± 0.114 g/cm(2) vs. FLEX, -0.020 ± 0.110 g/cm(2); p = 0.03). POWIR prevented increases in %BF (POWIR, 0.01 % vs. FLEX, 1.3 %; p < 0.04). Women with attendance to POWIR at ≥64 % had better improvements in %BF than women attending less often (p < 0.03).

CONCLUSION

Impact + resistance training may effectively combat bone loss and worsening body composition from premature menopause in BCS.

Outcome after laparoscopic gastric bypass for super-super obese patients

GOAL

The surgical treatment of the super-super obese (SSO), defined by a body mass index (BMI) superior or equal to 60 kg/m2, is difficult. The goal of this study was to evaluate the results of laparoscopic gastric bypass (LGBP) in this setting.

PATIENTS AND METHODS

Between June 2005 and December 2011, 20 SSO patients underwent LGBP by one surgeon. Postoperative complications, weight loss, evolution of co-morbidities and quality of life were analyzed. The Bariatric Analysis and Reporting Outcome System (BAROS) was used to classify outcomes.

RESULTS

There were 15 women and five men (median age: 37.5 years). Median BMI was 63 kg/m2. Median duration of operation was 180 minutes. One patient was converted to laparotomy. Three complications occurred: one grade I, one grade II and one grade V. The median excess weight loss was 47.1% at 12 months, 55.3% at 24 months, 53.3% at 36 months and 55.3% at 48 months. Among the patients with a follow-up of at least 12 months (n=17), the median quality of life score was 1.75 and the median BAROS score was 5.75. Arterial hypertension and type II diabetes resolved or improved in all patients and sleep apnea resolved in almost half of patients (43%).

CONCLUSIONS

LGBP appears feasible and effective for SSO, both in terms of weight loss and improvement of co-morbidities and quality of life as well, with a low rate of postoperative complications.

Educational Campaign on Stroke in an Urban Population in Northern Germany: Influence on Public Stroke Awareness and Knowledge

Background

Public stroke awareness and knowledge may be supportive for stroke prevention and emergency care-seeking behavior after the acute event, which is highly important for early treatment onset.

Aims

In an urban population in Northern Germany (Hannover), a six-month stroke educational campaign was conducted. We expected an increase in stroke knowledge and awareness thereafter.

Methods

Computer-assisted telephone interviews were randomly conducted among 1004 representative participants before and 1010 immediately after the educational multimedia campaign. The computer-assisted telephone interviews focused on questions about stroke knowledge and interventions remembered.

Results

Knowledge of stroke risk factors increased during the campaign for overweight, physical inactivity, old age, and stroke in family ( P < 0·05). The knowledge of stroke warning signs was low, although it significantly increased during the campaign ( P < 0·001) as paresis/weakness (46%) and speech problems (31%) were most frequently named. The majority of respondents indicated that the first action after suffering from stroke should be calling emergency care (74% before vs. 84% after campaign, P < 0·001).

Conclusions

Our data indicate that stroke knowledge and awareness, which could provide earlier presentation to the emergency unit for timely treatment onset, are still low in urban Northern Germany but may decisively be increased by educational campaigns.
