Mapping the Gap: Understanding the Need for Occupational Therapy Among Older Adults With Visual Impairment.

IMPORTANCE: Visual impairment (VI) affects more than 9 million Americans age 65 yr and older, and it limits meaningful participation in daily living. Occupational therapy can have a considerable impact on the functional performance of those with VI; however, information is limited on the existing occupational therapy services available for older adults with VI across the United States. OBJECTIVE: To calculate the prevalence of VI by U.S. county and quantify and locate the existing occupational therapy practitioners with certification in vision rehabilitation. DESIGN: Synthetic estimation was used to calculate the prevalence of VI among those age 65 yr and older in the United States by county. Geographic Information Systems mapping was used to illustrate the prevalence of VI and availability of occupational therapy practitioners with specialized training in vision rehabilitation by U.S. town. RESULTS: Communities with high concentrations of older adults with VI were more prevalent in the center of the United States, whereas occupational therapy practitioners with specialty training in vision rehabilitation were concentrated primarily on the east coast of the United States, on both Florida coasts, in selected cities in Texas and California, in western Pennsylvania, and in Alabama. CONCLUSIONS AND RELEVANCE: The availability of occupational therapy practitioners with specialty training in vision rehabilitation does not match the visual rehabilitation needs of older adults in the United States. These findings can be used to prioritize efforts for new service provision, provide outreach to underserved populations, and guide occupational therapy education to improve access to vision rehabilitation throughout the United States. What This Article Adds: The data provided in this study can inform resource allocation, workforce development, and entry-level occupational therapy education to address the ongoing needs of older adults with VI.

Hospitalisation Is Prognostic of Survival in Chronic Thromboembolic Pulmonary Hypertension.

This analysis investigated the prognostic value of hospitalisation in chronic thromboembolic pulmonary hypertension (CTEPH) using data from the Czech Republic, wherein pulmonary endarterectomy (PEA) was the only targeted treatment option until 2015. Using a landmark method, this analysis quantified the association between a first CTEPH-related hospitalisation event occurring before 3-, 6-, 9-, and 12-month landmark timepoints and subsequent all-cause mortality in adult CTEPH patients diagnosed between 2003 and 2016 in the Czech Republic. Patients were stratified into operable and inoperable, according to PEA eligibility. CTEPH-related hospitalisations were defined as non-elective. Hospitalisations related to CTEPH diagnosis, PEA, balloon pulmonary angioplasty, or clinical trial participation were excluded. Of 436 patients who survived to ≥3 months post diagnosis, 309 were operable, and 127 were inoperable. Sex- and age-adjusted hazard ratios (HRs) showed CTEPH-related hospitalisation was a statistically significant prognostic indicator of mortality at 3, 9, and 12 months in inoperable patients, with an approximately 2-fold increased risk of death in the hospitalisation group (HRs [95% CI] ranging from 1.98 [1.06-3.70] to 2.17 [1.01-4.63]). There was also a trend of worse survival probabilities in the hospitalisation groups for operable patients, with the difference most pronounced at 3 months, with a 76% increased risk of death (adjusted HR [95% CI] 1.76 [1.15-2.68]). This first analysis on the prognostic value of CTEPH-related hospitalisations demonstrates that a first CTEPH-related hospitalisation is prognostic of mortality in CTEPH, particularly for inoperable patients. These patients may benefit from medical and/or interventional therapy.

Epidemiology of chronic thromboembolic pulmonary hypertension (CTEPH) in the Czech Republic.

This study investigated the epidemiology and survival outcomes of chronic thromboembolic pulmonary hypertension (CTEPH) in the Czech Republic, wherein pulmonary endarterectomy (PEA) surgery was the only targeted treatment option until 2015. This study included all consecutive adults newly diagnosed with CTEPH in the Czech Republic between 2003 and 2016. Incidence/prevalence rates were calculated using general population data extracted from the Institute of Health Information and Statistics of the Czech Republic. Kaplan-Meier estimates of survival from diagnosis until 2018 were calculated. Of a total of 453 patients observed, 236 (52.1%) underwent PEA (median time from diagnosis to PEA: 2.9 months) and 71 (34.1%) had residual pulmonary hypertension (PH) post-PEA. CTEPH incidence rate (95% confidence interval [CI]) between 2006 and 2016 was 4.47 (4.05; 4.91) patients per million (ppm) per year, and the prevalence (95% CI) was 37.43 (33.46; 41.73) ppm in 2016. The rate of CTEPH-related hospitalizations (95% CI) per 100 person-years was 24.4 (22.1; 26.9) for operated patients and 34.2 (30.9; 37.7) for not-operated patients. Median overall survival (95% CI) for all patients from CTEPH diagnosis was 11.2 (9.4; not reached) years. Five-year survival probability (95% CI) was 95.3% (89.9; 97.9) for operated patients without residual PH, 86.3% (75.3; 92.7) for operated patients with residual PH and 61.2% (54.0; 67.6) for not-operated patients. This study reported epidemiological estimates of CTEPH in the Czech Republic consistent with estimates from other national systematic registries; and indicates an unmet medical need in not-operated patients and operated patients with residual PH.

A patient with pulmonary hypertension waiting for donor lungs during the pandemic: 194 days on extracorporeal life support including 143 days on pulmonary artery to left atrium shunt.

Patients with pulmonary hypertension and end-stage lung disease are fraught with high mortality while on a waiting list for lung transplant. With sometimes rapid deterioration they may require veno-arterial extracorporeal membrane oxygenation (VA-ECMO) as an immediate life-saving technique, which is a time-limited solution. The technique of pulmonary artery to left atrium (PA-LA) shunt fitted with an oxygenator enables bridging the patient to transplant for a longer time period. This low-resistance paracorporeal pumpless lung assist device allows for de-adaptation of the right ventricle back to lower afterload before the lung transplantation is carried out. The PA-LA shunt with an oxygenator also conveys a risk of multiple complications with reported median of 10-26 days until transplant. We report a case of pulmonary capillary hemangiomatosis in a 35-year-old female who had to wait for donor lungs during the pandemic of SARS-CoV-2 for 143 days on PA-LA shunt with oxygenator following 51 days on VA-ECMO. The extremely long course associated with multiple complications including three cerebral embolisms, episodes of sepsis and ingrowth of the return cannula into the left ventricular wall gives insight into the limits of this bridging technique.

Balloon Pulmonary Angioplasty in Patients with Chronic Thromboembolic Pulmonary Hypertension: Impact on Clinical and Hemodynamic Parameters, Quality of Life and Risk Profile.

Balloon pulmonary angioplasty (BPA) is a novel treatment option for patients with chronic thromboembolic pulmonary hypertension (CTEPH) who are not eligible for pulmonary endarterectomy (PEA) or suffer from persistent pulmonary hypertension after PEA. The aim of this study was to evaluate the real-life efficacy and safety of BPA in a consecutive group of patients who were diagnosed and treated in the national referral center for CTEPH in the Czech Republic. Here we report data from 160 BPA procedures performed in 64 patients. Efficacy analysis was performed in the subgroup of 25 patients who completed BPA series. Significant improvements were observed in New York Heart Association functional class (4% to 79% in I/II, p < 0.001), 6 min walking test distance (+54.3 m, p < 0.001), risk profile (15.8% to 68.5% with presence of 2/3 low risk criteria, p < 0.001), pulmonary artery mean pressure (-18%, p < 0.001), pulmonary vascular resistance (-32%, p < 0.001), stroke volume (+17%, p = 0.011) and quality of life (+37% in assessment of overall health status by a patient, p < 0.001). We observed 1 fatal periprocedural complication (1.6% of all 64 patients) and 19 BPA-related non-fatal complications (11.9% of all 160 interventions) that predominantly included hemoptysis (10.0% of all sessions). Overall survival at 12 months was 94.6%.

How to recognize stent graft infection after endovascular aortic repair: the utility of 18F-FDG PET/CT in an infrequent but serious clinical setting.

OBJECTIVE: To evaluate the diagnostic performance of 18F-FDG PET/CT in the detection of stent graft infection (SGI). METHODS: In a retrospective study, two nuclear medicine physicians have independently analyzed 17 18F-FDG PET/CT examinations performed for clinical suspicion of SGI. The images were evaluated for the uptake pattern and intensity, and by the maximum standard uptake value (SUVmax), the target-to-background ratio with blood pool (TBRBP) and liver uptake (TBRhep) as a reference. The SGI was defined as the presence of focal hyperactivity with an intensity exceeding hepatic uptake. CT images were independently assessed for signs of SGI. Clinical review of all further patients' data served as the standard of reference. RESULTS: Nine cases were established as SGI by the clinical review. PET/CT correctly diagnosed SGI in eight and yielded a sensitivity of 89% and specificity of 100%. The mean SUVmax, TBRBP, and TBRhep values were 9.8 ± 4.0, 6.9 ± 2.6, and 4.6 ± 1.7 in the group of patients with true SGI, and 4.0 ± 1.1, 2.5 ± 0.4 (p < 0.001) and 1.9 ± 0.2 (p < 0.001) in true negative cases, respectively. CT alone showed a sensitivity of 78% and specificity of 100% and was concordant with PET/CT in 14 cases. The best performing threshold values of SUVmax, TBRBP, and TBRhep were 5.6, 3.5, and 2.2, respectively. CONCLUSION: 18F-FDG PET/CT with expert evaluation, semiquantitative and quantitative image analysis with the proposed threshold values for SUVmax, TBRBP, and TBRhep has good diagnostic accuracy in the detection of SGI. We propose that visual grading scale for SGI should use hepatic uptake as a visual reference.

Percutaneous Mechanical Thrombectomy Using Rotarex® S Device in Acute Limb Ischemia in Infrainguinal Occlusions.

PURPOSE: To evaluate the effectiveness of percutaneous mechanical thrombectomy using Rotarex S in the treatment of acute limb ischemia (ALI) in infrainguinal occlusions in a retrospective study of patients treated in our institution. METHODS: In this study, we identified a total of 147 ALI patients that underwent mechanical thrombectomy using Rotarex S at our institution. In 82% of the cases, percutaneous thrombectomy was used as first-line treatment, and for the remainder of the cases, it was used as bailout after ineffective aspiration or thrombolysis. Additional fibrinolysis and adjunctive aspirational thrombectomy were utilized for outflow occlusion when required. Procedural outcomes, amputation rate, and mortality at 30 days were evaluated. RESULTS: Of the 147 patients treated with mechanical thrombectomy, Rotarex S was used as first-line treatment in 120 cases and as second-line treatment in 27 cases. Overall, we achieved 90.5% procedural revascularization success rate when combining mechanical thrombectomy with limited thrombolysis for severe outflow obstruction, and 1 death and 3 amputations were observed. We achieved primary success in 68.7% of the patients with the mechanical thrombectomy only, and in 21.8% of the patients, we successfully used additional limited thrombolysis in the outflow. The overall mortality was 0.7% and amputation rate was 2% at 30 days. CONCLUSION: Percutaneous mechanical thrombectomy as first-line mini-invasive treatment in infrainguinal ALI is safe, quick, and effective, and the performance outcomes can be superior to that of traditional surgical embolectomy.

Puncture and wiring of extracorporeal circuit for cannula safe removal or exchange.

A previously undescribed technique for removing a cannula used in extracorporeal life support (ECLS) is proposed, using an over-the-wire technique by puncturing the circuit and continuing with a pre-close technique for access site closure.

Association of -344/T/C aldosterone synthase polymorphism (CYP11B2) with left ventricular structure and humoral parameters in young normotensive men.

BACKGROUND: Aldosterone plays an important role in development of left ventricular (LV) hypertrophy and myocardial fibrosis. We assessed the influence of the T-344C polymorphism of aldosterone synthase - the rate-limiting enzyme in aldosterone biosynthesis - on the structure of the left ventricle in young normotensive men. DESIGN AND METHODS: The population included 113 normotensive mid-European Caucasian men aged 18-40 years (mean 27 +/- 5 years). The genotype was assessed using polymerase chain reaction with subsequent cleavage with restriction enzyme HAEIII (restriction fragment length polymorphism method) and visualization with ethidium bromide. Plasma renin activity (PRA) and plasma aldosterone were measured. All subjects were examined by echocardiography and LV mass was assessed by using M-mode based ASE formula. RESULTS: The distribution of the genotypes was TT 23%:TC 55%:CC 22%. There were no differences in blood pressure among the groups. Men with the TT genotype had significantly higher levels of PRA (2.7 +/- 1.7 vs 1.8 +/- 1.0 vs 1.8 +/- 1.1 ng/ml/h, p < 0.01) and slightly higher plasma levels of aldosterone (113 +/- 64 vs 93 +/- 43 vs 87 +/- 39 pg/ml, p = 0,12). In the whole population, LV mass index (LVMI) did not differ significantly among the genotypes (92 +/- 16 vs 86 +/- 18 vs 84 +/- 16 g/m, p=0.20). In the population divided according to PRA, subjects with high renin had significantly higher LVMI in presence of the TT genotype (95 +/- 17 vs 84 +/- 16 vs 81 +/- 15 g/m, p < 0.05). CONCLUSIONS: In agreement with previous studies, we found that the TT genotype of T-344C polymorphism of aldosterone synthase gene was associated with significantly higher levels of PRA in normotensive men. In subjects with high PRA, the TT genotype was associated with higher values of the LVMI.
