Physical Activity After Surgery for Severe Obesity: The Role of Exercise Cognitions

# The Author(s) 2010. This article is published with open access at Springerlink.com Background Physical activity after bariatric surgery is associated with sustained weight loss and improved quality of life. Some bariatric patients engage insufficiently in physical activity. This may be due to exercise cognitions, i.e., specific beliefs about benefits of and barriers to physical exercise. The aim of this study was to examine whether and to what extent both physical activity and exercise cognitions changed at 1 and 2 years post-surgery and whether exercise cognitions predict physical activity. Methods Forty-two bariatric patients (38 women, 4 men; mean age 38±8 years, mean body mass index prior to surgery 47±6 kg/m 2) filled out self-report instruments to examine physical activity and exercise cognitions pre- and post-surgery

Pharmacists\u27 Role in Opioid Safety: A Focus Group Investigation

Objective: The pharmacist’s role and responsibilities in addressing the opioid epidemic have yet to be clearly defined, particularly from the patient’s point of view. This qualitative study explores the pharmacist’s role in promoting opioid safety from the perspective of pharmacists and patients. Design: Focus groups. Setting: Patient groups were held in person, and pharmacist groups were held online. Subjects: Oregon pharmacists (N = 19, Mage = 39.0 years, range = 26–57 years, 58% female) and patients (N = 18, Mage = 60.1 years, range = 30–77 years, 71% female) with current experience dispensing or receiving opioid medications. Methods: Pharmacists were asked about the challenges and opportunities for opioid safety monitoring and prescription dispensing. Patients were asked about their experiences accessing care, medications, and safety information. Focus group data were analyzed by a multidisciplinary team using an immersion-crystallization approach. Results: Pharmacists and patients agreed that pharmacists are responsible for medication safety. Pharmacists expressed discomfort filling potentially high-risk opioid prescriptions and noted barriers such as lack of clinical information and discomfort policing high-risk prescribing. Patients were concerned about pharmacists potentially overstepping their professional responsibilities by interfering with prescribers’ clinical decisions. Conclusions: Feedback from both pharmacists and patient participants suggests that there is uncertainty in the degree to which pharmacists can and should confront the prescription opioid epidemic directly. Ambiguities in the pharmacist’s role may be best clarified through structured training promoting enhanced between-party communication

Evidence of potent humoral immune activity in COVID19-infected kidney transplant recipients

Whether kidney transplant recipients are capable of mounting an effective anti-SARS-CoV-2 adaptive immune response despite chronic immunosuppression is unknown and has important implications for therapy. Herein, we analyzed peripheral blood cell surface and intracellular cytokine phenotyping by flow cytometry along with serum antibody testing in 18 kidney transplant recipients with active COVID-19 infection and 36 matched, transplanted controls without COVID-19. We observed significantly fewer total lymphocytes, fewer circulating memory CD4+ and CD8+ T cells in the COVID-19 subjects. We also showed fewer anergic and senescent CD8+ T cells in COVID-19 individuals, but no differences in exhausted CD8+ T cells, nor in any of these CD4+ T cell subsets between groups. We also observed greater frequencies of activated B cells in the COVID-19 patients. Sixteen of 18 COVID-19 subjects tested for anti-SARS-CoV-2 serum antibodies showed positive IgM or IgG titers. Additional analyses showed no significant correlation s among immune phenotypes and degrees of COVID-19 disease severity. Our findings indicate that immunosuppressed kidney transplant recipients admitted to the hospital with acute COVID-19 infection can mount SARS-CoV-2-reactive adaptive immune responses. The findings raise the possibility that empiric reductions in immunosuppressive therapy for all kidney transplant recipients with active COVID-19 may not be required

Whether kidney transplant recipients are capable of mounting an effective anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) adaptive immune response despite chronic immunosuppression is unknown and has important implications for therapy. Herein, we analyzed peripheral blood cell surface and intracellular cytokine phenotyping by flow cytometry along with serum antibody testing in 18 kidney transplant recipients with active coronavirus disease 2019 (COVID-19) infection and 36 matched, transplanted controls without COVID-19. We observed significantly fewer total lymphocytes and fewer circulating memory CD4+ and CD8+ T cells in the COVID-19 subjects. We also showed fewer anergic and senescent CD8+ T cells in COVID-19 individuals, but no differences in exhausted CD8+ T cells, nor in any of these CD4+ T cell subsets between groups. We also observed greater frequencies of activated B cells in the COVID-19 patients. Sixteen of 18 COVID-19 subjects tested for anti-SARS-CoV-2 serum antibodies showed positive immunoglobulin M or immunoglobulin G titers. Additional analyses showed no significant correlation among immune phenotypes and degrees of COVID-19 disease severity. Our findings indicate that immunosuppressed kidney transplant recipients admitted to the hospital with acute COVID-19 infection can mount SARS-CoV-2-reactive adaptive immune responses.
