Development and Evaluation of the 8-item Caregiver Self-Efficacy Scale (CSES-8). The Gerontologist Ritter, P. L., Sheth, K., Stewart, A. L., Gallagher-Thompson, D., Lorig, K. 2020
Abstract

This paper describes the development and evaluation of a short caregiving self-efficacy measure. The self-administered 8-item Caregiver Self-efficacy Scale (CSES-8) was developed to reflect components of typical caregiver-support interventions and to be practical for inclusion in future self-efficacy and caregiving research.We administered the CSES-8 in two samples: participants in an intervention for caregivers of persons with cognitive disabilities, and a voluntary on-line survey for caregivers of adults. We evaluated the completion rate, item-scale correlations, reliability, descriptive statistics, and preliminary construct validity of the CSES-8 in both samples, and sensitivity to change in the intervention sample.The intervention caregivers' sample (N=158) was 85% female (mean age=65 years). The on-line survey sample (N=138) was 90% female (mean age=78). In both samples, the CSES-8 had excellent internal-consistency reliability (0.89 and 0.88) and good distribution with sufficient variability to detect change. Test-retest reliability was good in the on-line sample (0.73). As evidence of construct validity, most hypotheses were confirmed in both samples. The CSES-8 was sensitive to change at 6 months for caregivers in the intervention program (p < .001).The CSES-8 is short, comprehensive with respect to common components of interventions to improve caregivers' quality of life, and sensitive to change. It can serve a useful role exploring mechanisms by which caregiver intervention studies work, and it can be helpful in examining whether self-efficacy mediates the effect of these intervention on various outcomes such as psychological well-being.

Effects of COVID-19 on Informal Caregivers and the Development and Validation of a Scale in English and Spanish to Measure the Impact of COVID-19 on Caregivers. Journal of applied gerontology : the official journal of the Southern Gerontological Society Sheth, K., Lorig, K., Stewart, A., Parodi, J. F., Ritter, P. L. 2020: 733464820971511
Abstract

To understand how the COVID-19 pandemic has affected caregivers, we assessed its perceived impact on caregiving through a new measure: the Caregiver COVID-19 Limitations Scale (CCLS-9), in Spanish and English. We also compared levels of caregiver self-efficacy and burden pre-COVID-19 and early in the pandemic. We administered surveys via internet to a convenience sample of caregivers in January 2020 (pre-pandemic, n = 221) and in April-June 2020 (English, n = 177 and Spanish samples, n = 144) to assess caregiver self-efficacy, depression, pain, and stress. We used the early pandemic surveys to explore the validity of the CCLS-9. The pre-COVID-19 survey and the April English surveys were compared to determine how the COVID-19 pandemic affected caregivers. The CCLS-9 had strong construct and divergent validity in both languages. Compared to pre-COVID-19, caregiver stress (p = .002) and pain (p = .009) were significantly greater early in COVID-19, providing evidence of its validity. COVID-19 added to caregiver stress and pain.

Development and validation of a rheumatologist satisfaction with practice scale: The rheumatologist satisfaction scale. Medicine Sheth, K., Valenzuela, A., Shoor, S., Ritter, P. L., Lorig, K. 2019; 98 (48): e18114
Abstract

There is a paucity of succinct measures of physician satisfaction. As part of a Performance Improvement Project, we developed and piloted a simple questionnaire to determine rheumatologists satisfaction.Thirty 5 rheumatologists in the academic or private setting were sent opened-ended questions to determine the factors that made them satisfied or dissatisfied with respect to their rheumatology practice. From the responses we formed 14 questions 1 to 10 scale centering on satisfaction and dissatisfaction that was piloted in 30 rheumatologists and subsequently validated in 173 rheumatologists within the US and Latin America.Our combined sample included 173 rheumatologists (55 English and 118 Spanish-speaking respondents). The mean satisfaction for the combined sample was 6.92 (standard deviation=1.1, range 4.08-9.62). The strongest contributors to physician satisfaction were "Seeing interesting and challenging cases" (8.6?�?1.5) and "The ability to make a difference in patient's life" as well as "Establishing long term relationship with patients" (8.39?�?1.5). The strongest contributors to physician dissatisfaction were "Getting inappropriate referrals not in the scope of practice" (4.3?�?2.13) and "Time spent on documentation" (4.5?�?2.59). The scale had good reliability, relatively normal distribution, and little or no redundancy among items.A simple and practical questionnaire to measure physician satisfaction, in particular rheumatologists satisfaction, was developed, piloted and successfully validated on a predominately academic sample of rheumatologists within the US and Latin America. This scale will serve as a means to identifying potential barriers to the implementation of performance improvement projects in the practice of Rheumatology.

TNF-alpha inhibition for the treatment of cardiac sarcoidosis. Seminars in arthritis and rheumatism Baker, M. C., Sheth, K., Witteles, R., Genovese, M. C., Shoor, S., Simard, J. F. 2019
Abstract

Tumor necrosis factor alpha (TNF-?) inhibitors are increasingly being used for treating refractory cardiac sarcoidosis. There is a theoretical risk, however, that these therapies can worsen heart failure, and reports on efficacy and safety are lacking.We conducted a retrospective review of all cardiac sarcoidosis patients seen at Stanford University from 2009 to 2018. Data were collected on patient demographics, diagnostic testing, and treatment outcomes.We identified 77 cardiac sarcoidosis patients, of which 20 (26%) received TNF-? inhibitor treatment. The majority were treated for progressive heart failure or tachyarrhythmia, along with worsening imaging findings. All TNF-? inhibitor treated patients demonstrated meaningful benefit, as assessed by changes in advanced imaging, echocardiographic measures of cardiac function, and prednisone use.A large cohort (n�=�77) of cardiac sarcoidosis patients has been treated at Stanford University. Roughly one-fourth of these patients (n�=�20) received TNF-? inhibitors. Of these patients, none had worsening heart failure and all saw clinical benefit. These results help support the use of TNF-? inhibitors for the treatment of cardiac sarcoidosis based on real-world evidence and highlight the need for future prospective studies.

Recurrent carpal tunnel syndrome associated with extension of flexor digitorum muscle bellies into the carpal tunnel: A case series. Archives of plastic surgery Castillo, R., Sheth, K., Babigian, A., Scola, C. 2018; 45 (5): 474?78
Abstract

While the success or failure of carpal tunnel release ultimately depends on the interplay of a wide array of factors, a broad understanding of the normal anatomy of the carpal tunnel accompanied by awareness of the possible variations of the individual structures that make up its contents is crucial to optimizing surgical outcomes. While anatomic variants such as extension of the flexor digitorum muscle bellies have been described as a cause of primary carpal tunnel syndrome (CTS), there have been no reports depicting its association with recurrent CTS following initially successful carpal tunnel release, a finding with potentially significant prognostic implications that can aid in operative planning. In such cases where muscle extension is identified preoperatively, careful debulking of the muscle belly may be beneficial in improving long-term surgical outcomes.

Bilateral Giant Cell Arteritis Presenting as Bilateral Sudden Vision Loss. Connecticut medicine Modi, D. K., Sheth, K., Wade, S., Castillo, R., Nanavaty, S., Ali, S. S. 2017; 81 (4): 235?36
Abstract

Giant cell arteritis (GCA) is the most common form of primary vasculitis and it mainly involves large to medium sized vessels. It is also referred to as temporal arteritis as it primarily affects the temporal artery. Ocular involvement frequently occurs in GCA; if not promptly diagnosed, it can cause devastating ocular complications including complete vision loss and permanent blindness. In the majority of cases, it is unilateral; however, there are rare instances where bilateral ocular involvement is reported. In our report, we present the case of a patient presenting with bilateral sudden vision loss associated with GCA.

Risk of hemorrhagic transformation after ischemic stroke in patients with antiphospholipid antibody syndrome. Neurological research Mehta, T., Hussain, M., Sheth, K., Ding, Y., McCullough, L. D. 2017: 1?7
Abstract

Several rheumatologic conditions including systemic lupus erythematosus, antiphospholipid antibody (APS) syndrome, rheumatoid arthritis, and scleroderma are known risk factors for stroke. The risk of hemorrhagic transformation after an acute ischemic stroke (AIS) in these patients is not known.We queried the Nationwide Inpatient Sample (NIS) data between 2010 and 2012 with ICD 9 diagnostic codes for AIS. The primary outcome was the development of hemorrhagic transformation. Multivariate predictors for hemorrhagic transformation were identified with a logistic regression model. Using SAS 9.2, Survey procedures were used to accommodate for hierarchical two stage cluster design of NIS.APS (OR 2.57, 95% CI 1.14-5.81, p�=�0.0228) independently predicted risk of hemorrhagic transformation in multivariate regression analysis. Similarly, in multivariate regression models for the outcome variables of total charges of the hospitalization and length of stay (LOS), patients with APS had the highest charges ($56,286, p�=�0.0228) and LOS (3.87�days, p�=�0.0164) compared to other co-variates. Univariate analysis showed increased mortality in the APS compared to the non-APS group (11.68% vs. 7.16%, p�=�0.0024).APS is an independent risk factor for hemorrhagic transformation in both thrombolytic and non-thrombolytic treated patients. APS is also associated with longer length and cost of hospital stay. Further research is warranted to identify the unique risk factors in these patients to identify strategies to reduce the risk of hemorrhagic transformation in this subgroup of the population.

Cutaneous Vasculitis in a Patient with Antiphospholipid Antibody Syndrome. Connecticut medicine Sheth, K., Parke, A. 2016; 80 (2): 75-79
Abstract

Antiphospholipid antibody syndrome (APS) is an acquired thrombophilia, caused by autoantibodies to anticardiolipin (aCL), or antibeta 2 glycoprotein I, or the presence of lupus anticoagulant (LA) in plasma. It is characterized by recurrent venous and/or arterial thrombi and/or pregnancy related morbidities. We present the case of a 52-year-old female with long-standing APS, who developed cutaneous vasculitis following a common cold. Most of the cutaneous manifestations of APS have been found to be thrombotic on histopathology without evidence of perivascular inflammation. Vasculitis is usually seen in APS patients with coexistent Systemic Lupus Erythematosus (SLE). However, our patient had evidence of vasculitis on skin biopsy and did not have SLE. Though rare, this is a disease process which must be considered in patients with primary APS which must be closely monitored for other vasculitic complications of APS, particularly diffuse alveolar hemorrhage.

Autosplenectomy Causing Catastrophic Pneumococcal Meningitis in a Patient with Lupus/Antiphospholipid Antibody Syndrome. Connecticut medicine Sheth, K., Snyder, A., Wu, U., Lahiri, B., Grover, P. 2016; 80 (1): 37-38
Abstract

We present the case ofa26-year-old female who presented to the hospital with pneumococcal meningitis. A review of her records showed atrophic spleen, and a hypercoagulable workup was positive for Systemic Lupus Erythematous (SLE)/Antiphospholipid Antibody Syndrome (APS). An autosplenectomy from thrombotic occlusion of the splenic artery made her susceptible to pneumococcal meningitis. Autoimmune conditions, particularly SLE and APS, are important causes of hypercoagulable states in a young population, and earlier detection of these conditions and appropriate treatment helps to decrease morbidity and mortality among these patients.

Adult Onset Henoch-Sch�nlein Purpura: Case Report and Review of Literature. Connecticut medicine Sheth, K., Bockorny, M., Elaba, Z., Scola, C. 2015; 79 (2): 81-85
Abstract

Henoch-Sch�nlein purpura (HSP) is an IgA mediated small-vessel vasculitis, more common in children than adults. We present the case of a 37-year-old male who presented with complaints of nausea, vomiting, abdominal pain, purpuric rash over lower extremities, and migratory polyarthralgia five days after being treated with antibiotics for bronchitis. In addition to the abdominal pain, he developed diarrhea and colonic biopsy findings were suggestive of inflammatory bowel disease (IBD). Skin biopsy revealed leukocytoclastic vasculitis with direct immunofluorescence studies (DIF) staining of IgA deposition confirming the diagnosis of HSP. The clinical features of cutaneous eruption with abdominal complaints can be seen with either HSP or IBD; however the specific skin biopsy findings on DIF can distinguish between the two disease processes. Though HSP is primarily seen in the pediatric population, it is a disease process that must be considered in adults presenting with vasculitic skin rashes and abdominal complaints.

Efficacy and tolerability of pharmacotherapy options for the treatment of medullary thyroid cancer. Clinical Medicine Insights. Oncology Deshpande, H. A., Sheth, K., Sosa, J. A., Roman, S. 2012; 6: 355-362
Abstract

Metastatic and unresectable medullary thyroid carcinoma (MTC) is often difficult to treat as it is relatively unresponsive to radiation and conventional chemotherapy. This emphasizes the importance of the development of targeted therapies for advanced MTC. Vandetanib was approved by the US Food and Drug Administration for the treatment of symptomatic or progressive MTC in patients with advanced disease in April 2011. This therapy proved to be a breakthrough in the management of MTC. We review the efficacy and safety of this novel treatment and other treatments that are being evaluated in this disease.
