ABSTRACT

PURPOSE: To explore experiences of sheltering in place and accessing treatment during the initial stages of the COVID-19 pandemic among survivors with cancer receiving tyrosine kinase inhibitor (TKI) therapy. METHODS: Participants from two pilot studies evaluating TKI therapy use in the Southeastern United States during the start of the COVID-19 pandemic (March 2020) were interviewed. Identical interview guides were used across both studies to assess participants' experiences accessing cancer treatment, sheltering in place, and coping during the COVID-19 pandemic. Digitally recorded sessions were transcribed professionally and checked for accuracy. Descriptive statistics were used to summarize participant sociodemographics, and a six-step thematic approach was used to analyze interview data and identify salient themes. Dedoose qualitative research software was used to manage and organize qualitative codes, themes, and memos. RESULTS: Participants (n = 15) ranged from 43 to 84 years of age, and were mostly female (53.3%), married (60%), and survivors with hematologic malignancies (86.7%). The research team identified five salient themes: Participants followed pandemic guidelines, Variable impact on well-being, Common feelings of fear, anxiety and anger, No barriers to accessing therapy and medical care, and Faith and God as powerful forces for coping. CONCLUSIONS: The conclusions of the study provide several implications for survivorship programs or clinics for supporting survivors who are taking chronic TKI therapy during COVID-19, including enhancement of current psychosocial support efforts for cancer survivors or development of new programs tailored to the unique needs of a survivor during a pandemic, such as focused coping strategies, modified physical activity programs, family/professional role changes, and access to safe public spaces.

ABSTRACT

Pregnant women, children under 2 and the first thousand days of life have been principal targets for Developmental Origins of Health and Disease interventions. This paradigm has been criticized for laying responsibility for health outcomes on pregnant women and mothers and through the thousand days focus inadvertently deflecting attention from other windows for intervention. Drawing on insights from the South African context, this commentary argues for integrated and inclusive interventions that encompass broader social framings. First, future interventions should include a wider range of actors. Second, broader action frameworks should encompass life-course approaches that identify multiple windows of opportunity for intervention. Using two examples - the inclusion of men, and engagement with adolescents - this commentary offers strategies for producing more inclusive interventions by using a broader social framework.

ABSTRACT

Statements on childhood overweight and obesity (COO) have focused on different avenues for prevention and treatment, critical stages of the life cycle, including pregnancy and lactation, individual, family, school and community-based interventions, multidisciplinary family programmes and multicomponent interventions. This commentary is concerned with the less-addressed relationship between COO and inequality. It describes current global patterns of inequality and COO and the ways in which those inequalities are linked to COO at micro-level, meso-level and macro-level. It then describes current programmatic approaches for COO inequality, preventive and medical, and considers important pitfalls in the framing of the problem of COO and inequality. It ends with describing how childhood and adolescent overweight and obesity prevention and treatment programmes might be formulated within broader socio-political frameworks to influence outcomes.

ABSTRACT

BACKGROUND AND OBJECTIVES: The aim of this study is to report the incidence of Clostridium difficile-associated disease (CDAD) in a tertiary-care hospital in South Africa and to identify risk factors, assess patient outcomes and determine the impact of the hypervirulent strain of the organism referred to as North American pulsed-field type 1 (NAP1). METHODS: Adults who presented with diarrhoea over a period of 15 months were prospectively evaluated for CDAD using stool toxin enzyme immunoassay (EIA). Positive specimens were evaluated by PCR. Patient demographics, laboratory parameters and outcomes were analysed. RESULTS: CDAD was diagnosed in 59 (9.2%) of 643 patients (median age 39 years, IQR 30 - 55). Thirty-four (58%) were female. Recent antibiotic exposure was reported in 39 (66%), 27 (46%) had been hospitalised within 3 months, and 14 (24%) had concomitant inflammatory bowel disease (IBD). Nineteen (32%) had community-acquired CDAD (CA-CDAD). The annual incidence of hospital-acquired CDAD (HA-CDAD) was 8.7 cases/10 000 hospitalisations. Two cases of the hypervirulent strain NAP1 were identified. Seven (12%) patients underwent colectomy (OR 6.83; 95% CI 2.41 - 19.3). On logistic regression, only antibiotic exposure independently predicted for CDAD (OR 2.9; 95% CI 1.6 - 5.1). Three (16%) cases of CA-CDAD reported antibiotic exposure (v. 90% of HA-CDAD, p<0.0001). Twelve (86%) patients had concomitant IBD (p<0.0001 v. HA-CDAD). CA-CDAD was significantly associated with antibiotic exposure (OR 0.04, 95% CI 0.01 - 0.24) and IBD (OR 9.6, 95% CI 1.15 - 79.8). CONCLUSION: The incidence of HA-CDAD in the South African setting is far lower than that reported in the West. While antibiotic use was a major risk factor for HA-CDAD, CA-CDAD was not associated with antibiotic therapy. Concurrent IBD was a predictor of CA-CDAD.

ABSTRACT

The International Atomic Energy Agency (IAEA) has a mandate to assist member states in areas of human health and particularly in the use of radiation for diagnosis and treatment. Clinical audit is seen as an essential tool to assist in assuring the quality of radiation medicine, particularly in the instance of multidisciplinary audit of diagnostic radiology. Consequently, an external clinical audit programme has been developed by the IAEA to examine the structure and processes existent at a clinical site, with the basic objectives of: (1) improvement in the quality of patient care; (2) promotion of the effective use of resources; (3) enhancement of the provision and organisation of clinical services; (4) further professional education and training. These objectives apply in four general areas of service delivery, namely quality management and infrastructure, patient procedures, technical procedures and education, training and research. In the IAEA approach, the audit process is initiated by a request from the centre seeking the audit. A three-member team, comprising a radiologist, medical physicist and radiographer, subsequently undertakes a 5-d audit visit to the clinical site to perform the audit and write the formal audit report. Preparation for the audit visit is crucial and involves the local clinical centre completing a form, which provides the audit team with information on the clinical centre. While all main aspects of clinical structure and process are examined, particular attention is paid to radiation-related activities as described in the relevant documents such as the IAEA Basic Safety Standards, the Code of Practice for Dosimetry in Diagnostic Radiology and related equipment and quality assurance documentation. It should be stressed, however, that the clinical audit does not have any regulatory function. The main purpose of the IAEA approach to clinical audit is one of promoting quality improvement and learning. This paper describes the background to the clinical audit programme and the IAEA clinical audit protocol.

ABSTRACT

BACKGROUND: The histological differential diagnosis of Crohn's disease and intestinal tuberculosis can be very challenging, as both are chronic granulomatous disorders with overlapping histological features. AIM: To evaluate selected clinical and histological parameters in colonic biopsy specimens for their ability to discriminate between Crohn's disease and intestinal tuberculosis. METHODS: 25 patients with Crohn's disease and 18 patients with intestinal tuberculosis were selected for this study on the basis of established clinical, radiological and histological criteria. Clinical data and selected histological parameters in colonoscopic biopsy specimens were assessed retrospectively. A total of 103 and 41 biopsy sites were evaluated in patients with Crohn's disease and intestinal tuberculosis, respectively. RESULTS: Clinical parameters helpful in differentiating intestinal tuberculosis from Crohn's disease included chest radiographic features of tuberculosis (56% v 0%), perianal fistulae (0% v 40%) and extraintestinal manifestations of Crohn's disease (0% v 40%). Histopathological features that seemed to reliably differentiate between intestinal tuberculosis and Crohn's disease included confluent granulomas, > or =10 granulomas per biopsy site and caseous necrosis (in biopsy samples of 50%, 33% and 22% of patients with intestinal tuberculosis, respectively, v 0% of patients with Crohn's disease). Features that were observed more often in patients with intestinal tuberculosis than in those with Crohn's disease included granulomas exceeding 0.05 mm(2) (67% v 8%), ulcers lined by conglomerate epithelioid histiocytes (61% v 8%) and disproportionate submucosal inflammation (67% v 10%). CONCLUSION: Clinical features and selected histological parameters in colonoscopic biopsy specimens can help in differentiating between Crohn's disease and intestinal tuberculosis.

ABSTRACT

In this work, we characterize genes in Mycobacterium tuberculosis that are regulated by IdeR (iron-dependent regulator), an iron-responsive DNA-binding protein of the DtxR family that has been shown to regulate iron acquisition in Mycobacterium smegmatis. To identify some of the genes that constitute the IdeR regulon, we searched the M. tuberculosis genome for promoter regions containing the consensus IdeR/DxR binding sequence. Genes preceded by IdeR boxes included a set encoding proteins necessary for iron acquisition, such as the biosynthesis of siderophores (mbtA, mbtB, mbtI), aromatic amino acids (pheA, hisE, hisB-like) and others annotated to be involved in the synthesis of iron-storage proteins (bfrA, bfrB). Some putative IdeR-regulated genes identified in this search encoded proteins predicted to be engaged in the biosynthesis of lipopolysaccharide (LPS)-like molecules (rv3402c), lipids (acpP) and peptidoglycan (murB). We analysed four promoter regions containing putative IdeR boxes, mbtA-mbtB, mbI, rv3402c and bfrA-bfd, for interaction with IdeR and for iron-dependent expression. Gel retardation experiments and DNase footprinting analyses with purified IdeR showed that IdeR binds to these IdeR boxes in vitro. Analysis of the promoters by primer extension indicated that the IdeR boxes are located near the -10 position of each promoter, suggesting that IdeR acts as a transcriptional repressor by blocking RNA polymerase binding. Using quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) coupled to molecular beacons, we showed that mRNA levels of mbtA, mbtB, mbtI, rv3402c and bfd are induced 14- to 49-fold in cultures of M. tuberculosis starved for iron, whereas mRNA levels of bfrA decreased about threefold. We present evidence that IdeR not only acts as a transcriptional repressor but also functions as an activator of bfrA. Three of the IdeR- and iron-repressed genes, mbtB, mbtI and rv3402c, were induced during M. tuberculosis infection of human THP-1 macrophages.

ABSTRACT

OBJECTIVE: To determine the change in health-related quality of life associated with uterine fibroid embolization (UFE). MATERIALS AND METHODS: A health-related quality-of-life questionnaire was administered before and after therapy. The questionnaire contained validated scales from the Medical Outcomes Study, with additional domains and symptom items specific to fibroids. Patients treated with UFE for symptomatic uterine leiomyomata completed a health-related quality of life questionnaire before therapy. A follow-up quality of life questionnaire and an additional brief questionnaire to assess symptom improvement were completed 3 and 6 months postprocedure. Confirmatory reliability and validity testing was also conducted. Mean scores for each scale on the quality of life questionnaire were calculated and change scores were computed. RESULTS: Fifty women were enrolled in the study and completed the baseline assessment. Health-related quality of life scores improved in all instances at follow-up. Mean change scores were statistically significant for all domains between baseline and month 3 (P < .01) and between baseline and month 6 (P < .05) except backache (P = .12). CONCLUSION: Patients undergoing UFE report significant improvements in health-related quality of life and fibroid-specific symptoms. These findings suggest that the measurement of health-related quality of life may be an effective means of comparing the outcome of UFE with other fibroid therapies.

ABSTRACT

The hypotheses that data, available at the time when a medical school admission decision is made, can be used to predict generalist specialty choice and rural practice location were tested. Applicant data, available to admissions committee members at the University of Louisville in 1986 and 1987 about the classes of 1990 and 1991 respectively, were correlated with specialty choice and practice location in a retrospective cohort study. Data collected from 1994 to 1996 about the 1990 and 1991 graduates were used to develop a mathematical model to predict specialty choice and practice location using stepwise logistic regression. These models were more accurate in predicting which applicants would not select a generalist career (negative predictive value = 80.7%) than those who would (positive predictive value = 42.7%) and in predicting those who would not practice in a rural location (negative predictive value = 91.9%) than those who would (positive predictive value = 37.8%). We conclude that applicant data, available at the time admission decisions are made, are of limited value for identifying those who will eventually become generalist physicians or practice in a rural area. However, the data are useful for identifying those who will not.

ABSTRACT

PURPOSE: To compare the success of percutaneous varicocele embolization to surgical ligation with regard to changes in semen characteristics and pregnancy outcome. MATERIALS AND METHODS: Infertility records from 346 men who underwent correction of their varicocele for infertility (surgical ligation 149; embolization 197) were reviewed retrospectively. Preprocedural and postprocedural semen analyses and pregnancy outcomes were obtained with use of chart and telephone follow-up. RESULTS: In men who successfully impregnated their partners, there were significant improvements in sperm density, percent total improvement, motility, and progression. Postprocedural (embolization vs surgery) percentage increases in seminal parameters were density, 156.8% versus 138.5%; total, 168.8% versus 157.91%; and motility, 2.7% versus 3.2%. The percent of individuals who had a change in sperm progression was 31% versus 41%. There was no statistical difference between the techniques based on t tests. The pregnancy rates were similar for the two groups, 39% and 34% for embolization and surgery, respectively. CONCLUSION: There is no significant statistical difference in seminal values or pregnancy outcome between the two techniques.

ABSTRACT

Aortoenteric fistula is a rare complication of abdominal trauma. We present a case of a patient with multiple gunshot wounds to the abdomen and thorax in whom control of injury required staged operations. An aortoenteric fistula developed, presenting a diagnostic and therapeutic challenge. The operative control of aortic bleeding was by a retroperitoneal approach to the aorta and facilitated by the use of percutaneous aortic balloon catheters. The patient survived to leave hospital. This case highlights a rare trauma complication, the use of "damage control" for the severely injured abdomen and the technique of intra-arterial balloon control of bleeding from inaccessible locations.

ABSTRACT

PURPOSE: The authors prospectively compared the nature and incidence of hepatic arterial injuries resulting from creation of a transjugular intrahepatic portosystemic shunt (TIPS) with large- and small-gauge needle systems. PATIENTS AND METHODS: Fifty patients underwent hepatic and superior mesenteric angiography immediately before and after shunt creation. A sheathed 16-gauge needle system was used to locate and puncture the portal vein in 24 patients. A 21-gauge needle system was used in 26 patients. RESULTS: Shunts were successfully created in all patients. Three inadvertent hepatic arterial punctures were recognized during shunt placement, two with the small needle and one with the large needle system. No hepatic arterial lesions were detected in any patient. Two incidental hepatomas were identified at angiography. CONCLUSION: TIPS-related hepatic arterial injuries are rare. In this series, large and small needle systems were indistinguishable with respect to this complication.
