Patient navigation across the cancer care continuum: An overview of systematic reviews and emerging literature

Patient navigation is a strategy for overcoming barriers to reduce disparities and to improve access and outcomes. The aim of this umbrella review was to identify, critically appraise, synthesize, and present the best available evidence to inform policy and planning regarding patient navigation across the cancer continuum. Systematic reviews examining navigation in cancer care were identified in the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Embase, Cumulative Index of Nursing and Allied Health (CINAHL), Epistemonikos, and Prospective Register of Systematic Reviews (PROSPERO) databases and in the gray literature from January 1, 2012, to April 19, 2022. Data were screened, extracted, and appraised independently by two authors. The JBI Critical Appraisal Checklist for Systematic Review and Research Syntheses was used for quality appraisal. Emerging literature up to May 25, 2022, was also explored to capture primary research published beyond the coverage of included systematic reviews. Of the 2062 unique records identified, 61 systematic reviews were included. Fifty-four reviews were quantitative or mixed-methods reviews, reporting on the effectiveness of cancer patient navigation, including 12 reviews reporting costs or cost-effectiveness outcomes. Seven qualitative reviews explored navigation needs, barriers, and experiences. In addition, 53 primary studies published since 2021 were included. Patient navigation is effective in improving participation in cancer screening and reducing the time from screening to diagnosis and from diagnosis to treatment initiation. Emerging evidence suggests that patient navigation improves quality of life and patient satisfaction with care in the survivorship phase and reduces hospital readmission in the active treatment and survivorship care phases. Palliative care data were extremely limited. Economic evaluations from the United States suggest the potential cost-effectiveness of navigation in screening programs.     

Juvenile progressive systemic sclerosis: report of five cases

Five cases of juvenile progressive systemic sclerosis (SSc) are reported (4 girls and 1 boy). The age of onset of the disease ranged from 4 to 13 years. The clinical features included Raynaud's phenomenon present in 4 of 5 cases; hyperpigmentation, skin tightening and contractures of the large joints were noted in all 5 cases. One patient initially diagnosed as having eosinophilic fasciitis developed SSc 3 months later. Another patient was diagnosed initially as having juvenile rheumatoid arthritis. There was one case of pulmonary fibrosis and another of mild restrictive lung disease. Two cases of esophageal and intestinal hypomotility were reported. Scleroderma nephropathy was absent in all 5 cases.     

Chemoembolization in the therapy of hepatocarcinoma. A 3-year experience]

This study was aimed at evaluating the efficacy of chemoembolization (CE) to improve survival in patients with hepatocellular carcinoma (HCC). Our results were compared with the natural history of HCC. Sixty-two consecutive patients with HCC in Okuda's stages I and II underwent CE. Forty-seven patients were treated with CE alone; 9 patients had CE prior to surgery, and 6 patients had it after surgery because of recurrent HCC. One hundred and nine CEs (mean: 1.8 CEs/patient) were performed with Lipiodol UF, epirubicin and gelatin sponge. Actuarial survival was calculated considering Okuda's stage, neoplasm size, and evidence of pseudocapsule. The mean cumulative survival of the 47 patients treated with CE alone was 13.2 months; survival (+/- SE) at 12, 24 and 36 months was 0.75 (+/- 0.07), 0.46 (+/- 0.10) and 0.28 (+/- 0.12). Survival was not affected by Okuda's stage, neoplasm size, evidence of pseudocapsule (p > 0.05). Nevertheless, the patients with early HCC had better prognosis. Eighteen patients (42.9%) died during follow-up, 12 of whom (66.7%) from hepatic failure. The mean survival of patients with recurrence of HCC after surgery was 41 months (range: 24.8-74.9 months) since initial diagnosis of HCC, and 14.8 months (range: 7.1-29.6 months) since diagnosis of recurrence. Two of these patients died from hepatic failure. All the patients who underwent also surgery after CE are still alive (mean survival: 14.7 months). Histologic findings of resected specimens revealed viable neoplastic cells in all cases. Twenty-one major complications (20.2%) occurred in 18 patients (29%); the outcome of complications was favorable in all but one patient who died from sepsis. CE is a reliable and safe treatment for unresectable HCC. Small HCCs should be preferably treated with surgery or, alternatively, with percutaneous alcohol injection.     

Cancer by negative heterosis: breast and ovarian cancer excess in hybrids of inbred ethnic groups

Breast and ovarian cancer rates in Pakistan are significantly higher than in neighboring countries. The cancer rate discrepancies cannot be explained with discrepancies of their risk factors. We propose that observed cancer excess in Pakistan is due to cancer development by negative heterosis. Heterosis occurs when a hybrid has a phenotypic characteristic significantly different from that in either parent (hybrid vigor). At a molecular level, heterosis occurs in a heterozygote when one of the two alleles is inactivated. Gene inactivation occurs by methylation of cytosine in a promoter region of a gene. Initiation of allele inactivation is linked to the factors like stress, gender, diet, or another gene. In heterozygote, inactivation of one of the two tumor-suppressor alleles leads to monoallelic expression. This increases cancer risk in the same way the risk is increased in individual who inherit a single mutated tumor-suppressor gene (hereditary cancer syndrome). In both, cancer by heterosis and inherited cancer syndrome, cancer develops after inactivation of a second allele (second hit hypothesis). In a population, conditions that favor development of cancer by heterosis are those that favor mating of a large number of different homozygotes because they produce a large number of different heterozygotes. Among a large number of heterozygotes, there is an increased chance that some of hybrids will develop cancer by heterosis. In Pakistan, conditions were favorable for cancer development by heterosis because country has a high number of different ethnic groups and brotherhoods all of which have a higher rate of homozygosity due to a high frequency of consanguineous marriages, and marriages between members of different groups occurred because of intense population mixing. Result was birth of a large number of inter-ethnic/brotherhood hybrids (heterozygotes), some of which have developed cancer by heterosis.     

Combined sciatic-paravertebral nerve block vs. general anaesthesia for fractured hip of the elderly

Sixty elderly patients scheduled for surgical hip fracture repair were given the choice of either general isoflurane anaesthesia (n = 30) or a nerve stimulator guided combined sciatic-paravertebral nerve block (n = 30). The incidence of intraoperative hypotension and the need for postoperative admission to the intensive care unit/high dependency unit (ICU/HDU) within 48 hours postoperatively were recorded. No differences in patient characteristics, ASA class or concomitant disease status were detected between the two study groups. Both the incidence of intraoperative hypotension (0/30 vs. 11/30, p < 0.001) and the postoperative need for ICU/HDU admission (0/30 vs. 11/30, p < 0.001) was significantly reduced in patients treated with a combined sciatic-paravertebral nerve block compared to patient receiving general anaesthesia. The length of hospital stay was also found to be shorter for patient in the regional anaesthesia group [mean 6.7 days (SD 2.3) vs. 13.6 days (SD 6.1)]. The described technique appears to be an attractive alternative method to handle proximal fractures of the femur in the elderly, especially in a situation with limited ICU/HDU availability.     

The role of electronic medical records in improving health care quality: A quasi-experimental study

The Teleprimary Care—Oral Health Clinical Information System (TPC-OHCIS) is an updated electronic medical record (EMR) that has been applied in Malaysian primary healthcare. Recognizing the level of patient satisfaction following EMR implementation is crucial for assessing the performance of health care services. Hence, the main objective of this study was to compare the level of patient satisfaction between EMR-based clinics and paper-based clinics.The study was a quasi-experimental design that used a control group and was conducted among patients in 14 public primary healthcare facilities in the Seremban district of Malaysia from May 10, to June 30, 2021. Patient satisfaction was assessed using the validated Short-Form Patient Satisfaction Questionnaire, which consisted of 7 subscales. All data were analyzed using the IBM Statistical Package for Social Sciences version 21.A total of 321 patients consented to participate in this study, and 48.9% of them were from EMR clinics. The mean score for the communication subscale was the highest at 4.08 and 3.96 at EMR-adopted clinics and paper-based record clinics. There were significant differences in general satisfaction and communication subscales, with higher patient satisfaction found in clinics using EMR.With the utilization of EMR, patient satisfaction and communication in delivering healthcare services have improved.     

Unmasking Myocardial Dysfunction in Patients Hospitalized for Community-Acquired Pneumonia Using a 4-Chamber 3-Dimensional Volume/Strain Analysis

Lower respiratory infection was reported as the most common fatal infectious disease. Community-acquired pneumonia (CAP) and myocardial injury are associated; yet, true prevalence of myocardial injury is probably underestimated. We assessed the rate and severity of myocardial dysfunction in patients with CAP. Admitted patients diagnosed with CAP were prospectively recruited. All the patients had C-reactive protein (CRP), brain natriuretic peptide (BNP), and high-sensitivity cardiac troponin (hs-cTnl) tests added to their routine workup. 2D/3D Doppler echocardiography was done on a Siemens Acuson SC2000 machine ≤ 24 h of diagnosis. 3D datasets were blindly analyzed for 4-chamber volumes/strains using EchobuildR 3D-Volume Analysis prototype software, v3.0 2019, Siemens-Medical Solutions. Volume/strain parameters were correlated with admission clinical and laboratory findings. The cohort included 34 patients, median age 60 years (95% CI 55–72). The cohort included 18 (53%) patients had hypertension, 9 (25%) had diabetes mellitus, 7 (21%) were smokers, 7 (21%) had previous myocardial infarction, 4 (12%) had chronic renal failure, and 1 (3%) was on hemodialysis treatment. 2D/Doppler echocardiography findings showed normal ventricular size/function (LVEF 63 ± 9%), mild LV hypertrophy (104 ± 36 g/m²), and LA enlargement (41 ± 6 mm). 3D volumes/strains suggested bi-atrial and right ventricular dysfunction (global longitudinal strain RVGLS =  − 8 ± 4%). Left ventricular strain was normal (LVGLS =  − 18 ± 5%) and correlated with BNP (r = 0.40, p = 0.024). The patients with LVGLS >  − 17% had higher admission blood pressure and lower SaO₂ (144 ± 33 vs. 121 ± 20, systolic, mmHg, p = 0.02, and 89 ± 4 vs. 94 ± 4%, p = 0.006, respectively). hs-cTnl and CRP were not different. Using novel 3D volume/strain software in CAP patients, we demonstrated diffuse global myocardial dysfunction involving several chambers. The patients with worse LV GLS had lower SaO₂ and higher blood pressure at presentation. LV GLS correlated with maximal BNP level and did not correlate with inflammation or myocardial damage markers.
