Planning Transition of Care for Adolescents Affected by Congenital Heart Disease: The Irish National Pathway.

At some point in their life, adolescent patients with a congenital heart disease (CHD) transition from paediatric services to adult care facilities. The process is not without any risks, as it is often linked with a significantly progressive deterioration in adolescents' health and loss of follow-up. In fact, transition patients often encounter troubles in finding a care giver who is comfortable managing their condition, or in re-establishing trust with the new care provider. Planning the rules of transition is pivotal in preventing these risks. Unfortunately, the American and European guidelines on CHD provide just generic statements about transition. In a recently published worldwide inter-societies consensus document, a hybrid model of transition, which should be adapted for use in high- and low- resource settings, has been suggested. Currently, in literature there are a few models of transition for CHD patients, but they are by far local models and cannot be generalized to other regions or countries. This paper describes the Irish model for transition of care of CHD patients. Due to the peculiarity of the healthcare organization in the Republic of Ireland, which is centralized with one main referral centre for paediatric cardiology (in Dublin, with a few smaller satellite centres all around, according to the "hub and spoke" model) and one centre for adult with CHD (in Dublin), the model can be considered as a national one and the first to be released in the old continent.

Impact of COVID-19 pandemic on hospital onset bloodstream infections (HOBSI) at a large health system.

BACKGROUND: The COVID-19 pandemic has had a considerable impact leading to increases in health care-associated infections, particularly bloodstream infections (BSI). METHODS: We evaluated the impact of COVID-19 in 69 US hospitals on BSIs before and during the pandemic. Events associated with 5 pathogens (Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Candida sp.) were stratified by community onset (CO) if ≤ 3 days from admission or hospital onset (HO) if > 3 days after admission. We compared pre-pandemic CO and HO rates with pandemic periods and the rates of BSI for those with and without COVID-19. RESULTS: COVID-19 patients were less likely to be admitted with COBSI compared to others (10.85 vs 22.35 per 10,000 patient days; P < .0001). There was a significant increase between pre-pandemic and pandemic HOBSI rates (2.78 vs 3.56 per 10,000 patient days; P < .0001). Also, COVID-19 infected patients were 3.5 times more likely to develop HOBSI compared to those without COVID-19 infection (9.64 vs 2.74 per 10,000 patient-days; P < .0001). CONCLUSIONS: The COVID-19 pandemic period was associated with substantial increases in HOBSI and largely attributed to COVID-19 infected patients. Future research should evaluate whether such measures would be beneficial to incorporate in evaluating infection prevention trends.

Russell Body Lesions of the Colon: Case Report and Literature Review.

Russell bodies (RB) are rare manifestations within the lower gastrointestinal tract. To date, there are only three other reported cases of RB lesions of the colon; two were polyps, and the third was a case of a multifocal RB lesion of the gastrointestinal tract. This paper reports a case of a tubulovillous adenoma with RB of the sigmoid colon in a patient diagnosed incidentally as part of the UK National Health Service Bowel Cancer Screening Programme. A thorough hematological investigation is required to exclude hematological malignancies because of its association with plasma cell neoplasm. These lesions should undergo clonality analysis to exclude the monoclonal proliferation of plasma cells. Ideally, a bone marrow aspirate and investigations for amyloidosis should be performed to exclude underlying hematological malignancies.

Title: Expansion of a national differentiated service delivery model to support people living with HIV and other chronic conditions in South Africa: a descriptive analysis.

BACKGROUND: South Africa is home to 7.7 million people living with HIV and supports the largest antiretroviral therapy (ART) program worldwide. Despite global investment in HIV service delivery and the parallel challenge of non-communicable diseases (NCDs), there are few examples of integrated programs addressing both HIV and NCDs through differentiated service delivery. In 2014, the National Department of Health (NDoH) of South Africa launched the Central Chronic Medicines Dispensing and Distribution (CCMDD) program to provide patients who have chronic diseases, including HIV, with alternative access to medications via community-based pick-up points. This study describes the expansion of CCMDD toward national scale. METHODS: Yale monitors CCMDD expansion as part of its mixed methods evaluation of Project Last Mile, a national technical support partner for CCMDD since 2016. From March 2016 through October 2019, cumulative weekly data on CCMDD uptake [patients enrolled, facilities registered, pick-up points contracted], type of medication provided [ART only; NCD only; and ART-NCD] and collection sites preferred by patients [external pick-up points; adherence/outreach clubs; or facility-based fast lanes], were extracted for descriptive, longitudinal analysis. RESULTS: As of October 2019, 3,436 health facilities were registered with CCMDD across 46 health districts (88 % of South Africa's districts), and 2,037 external pick-up points had been contracted by the NDoH. A total of 2,069,039 patients were actively serviced through CCMDD, a significant increase since 2018 (p < 0.001), including 76 % collecting ART [64 % ART only, 12 % ART plus NCD/comorbidities] and 479,120 [24 %] collecting medications for chronic diseases only. Further, 734,005 (35 %) of patients were collecting from contracted, external pick-up points, a 73 % increase in patient volume from 2018. DISCUSSION: This longitudinal description of CCMDD provides an example of growth of a national differentiated service delivery model that integrates management of HIV and noncommunicable diseases. This study demonstrates the success of the program in engaging patients irrespective of their chronic condition, which bodes well for the potential of the program to address the rising burden of both HIV and NCDs in South Africa. CONCLUSIONS: The CCMDD program expansion signals the potential for a differentiated service delivery strategy in resource-limited settings that can be agnostic of the patients chronic disease condition.

Primary cardiac arrest following sport or exertion in children presenting to an emergency department: chest compressions and early defibrillation can save lives, but is intravenous epinephrine always appropriate?

OBJECTIVES: The objective of this study was to describe the characteristics and outcome of pediatric patients presenting to an emergency department (ED) following out-of-hospital primary cardiac arrest (OHPCA), to determine if long-term survival is influenced by specific resuscitation interventions. METHODS: This was a prospective observational study of cases of OHPCA during sport or exertion in young patients presenting to an ED over a 5-year period. Cases were identified from a resuscitation database, which documented patient demographics, nature of event, emergency treatment, response times, and clinical progress. These data were analyzed to determine outcomes. RESULTS: Nine children were identified who presented following OHPCA during the study period. The mean age was 10.7 (±4.2) years. All were subsequently diagnosed with an underlying primary cardiac disorder. Six patients (66.6%) survived to make a full recovery. All patients who survived had received early chest compressions (within 5 minutes) and early defibrillation (within 10 minutes). The initial cardiac arrest rhythm in all survivors had been an electrically cardiovertable rhythm. Five (83%) of the 6 survivors did not receive epinephrine during resuscitation. CONCLUSIONS: The importance of early chest compressions and defibrillation in collapsed young athletes is highlighted in this report. These interventions can result in full long-term neurological recovery. Use of epinephrine in these patients may be dangerous. We suggest that special consideration should be given to this subgroup of patients in the development of future resuscitation guidelines.

The effect of race and rural residence on prostate cancer treatment choice among men in Georgia.

OBJECTIVE: To analyze differences for prostate cancer by race and in rural areas. METHODS: We studied 516 men younger than 75 years old with incident prostate cancer during 2005-08 in 33 counties in Southwest Georgia (SWGA), a rural area of 700,000 (40% African American). Treatment data were abstracted from medical records, and interviews conducted with 314 men. We also compared treatments in SWGA vs. Atlanta in 2005. RESULTS: External radiation plus brachytherapy was the most common treatment in SWGA (31%), followed by external radiation alone (27%), and surgery (18%). Patients in SWGA had higher odds of external radiation vs. surgery than men in Atlanta (OR 2.66, 95% CI 1.85-3.81). African Americans had higher odds of choosing treatment other than surgery, compared with whites (OR 2.04, 95% CI 1.57-2.63), more so in SWGA (OR 3.51, 95% CI 1.92-6.41) than Atlanta (OR 1.76, 95% CI 1.32-2.35) (P = .05). Poor communication with their physician was reported by 13% of men in SWGA, more among African Americans than whites (OR 3.95, 95% CI 1.52-10.30), and more among those who had no treatment vs. some treatment (OR 5.77, 95% CI 1.88-11.46). CONCLUSIONS: In both rural and urban Georgia, white men with prostate cancer had surgery more frequently than African Americans, although data suggest this may be caused more by income differences than race. Rural patients as opposed to urban patients were more likely to receive external radiation and less likely to receive brachytherapy alone or surgery. Poor communication with a physician, particularly prevalent among African Americans, was associated with choosing no treatment in SWGA.

Liver and brain abscess caused by Aggregatibacter paraphrophilus in association with a large patent foramen ovale: a case report.

INTRODUCTION: Aggregatibacter paraphrophilus (former name Haemophilus paraphrophilus) is a normal commensal of the oral flora. It is a rare cause of hepatobiliary or intracerebral abscesses. CASE PRESENTATION: We report a case of a 53-year-old Caucasian man with a liver abscess and subsequent brain abscesses caused by Aggregatibacter paraphrophilus. The probable source of the infection was the oral flora of our patient following ingestion of a dental filling. The presence of a large patent foramen ovale was a predisposing factor for multifocal abscesses. CONCLUSION: In this case report, we describe an unusual case of a patient with both liver and brain abscesses caused by an oral commensal Aggregatibacter paraphrophilus that can occasionally show significant pathogenic potential.

Synthesis, antimalarial activity, and preclinical pharmacology of a novel series of 4'-fluoro and 4'-chloro analogues of amodiaquine. Identification of a suitable "back-up" compound for N-tert-butyl isoquine.

On the basis of a mechanistic understanding of the toxicity of the 4-aminoquinoline amodiaquine (1b), three series of amodiaquine analogues have been prepared where the 4-aminophenol "metabolic alert" has been modified by replacement of the 4'-hydroxy group with a hydrogen, fluorine, or chlorine atom. Following antimalarial assessment and studies on mechanism of action, two candidates were selected for detailed ADME studies and in vitro and in vivo toxicological assessment. 4'-Fluoro-N-tert-butylamodiaquine (2k) was subsequently identified as a candidate for further development studies based on potent activity versus chloroquine-sensitive and resistant parasites, moderate to excellent oral bioavailability, low toxicity in in vitro studies, and an acceptable safety profile.

A patient with bacteraemia and possible endocarditis caused by a recently-discovered genomospecies of Capnocytophaga: Capnocytophaga genomospecies AHN8471: a case report.

INTRODUCTION: Capnocytophaga are a genus of bacteria that have been found to be the causative organisms in a range of infections, including serious conditions such as bacteraemia, endocarditis and meningitis. This has been especially true amongst those with serious comorbidities and the immunocompromised populations. Although several species are known to cause human disease, historically, laboratories have often not identified isolates to species level due to the unreliable, laborious techniques needed. With the advent of Polymerase Chain Reaction-Restriction Fragment Length Polymorphism Analysis, identification to species level is now frequently possible and desirable, as it may provide clues as to the source of infection and its treatment. CASE PRESENTATION: Here we describe a case of bacteraemia and possible endocarditis in a 64-year-old white British man caused by a newly identified genomospecies of Capnocytophaga in a patient subsequently diagnosed with metastatic adenocarcinoma of the oesophagus. The source of the bacteraemia was presumed to be from the patient's own oral flora. CONCLUSION: Our case further confirms the potential for Capnocytophaga to cause systemic infections, highlights the availability and need for identification of isolates to species level and re-emphasises the difficulty in diagnosing Capnocytophaga infections due to their slow growth in the laboratory.

EXUBERA: pharmaceutical development of a novel product for pulmonary delivery of insulin.

Development of a product for pulmonary delivery of insulin presented significant technology challenges for this first-in-class pharmaceutical product. These included developing (a) a chemically stabilized protein, (b) a dry powder formulation exhibiting required aerosol physical characteristics, (c) low-dose powder filling and packaging technology, and (d) a mechanical device for powder dispersal and reliable dosing to the patient. The insulin drug is formulated using a novel excipient combination to create a powder with a high glass transition temperature (Tg). The high Tg minimizes insulin mobility (thus reactivity), enabling ambient storage conditions. The formulation composition results in minimal hygroscopicity, where customized packaging produced product ruggedness to humidity. The formulated insulin powder is manufactured by spray-drying. This technology was further engineered to produce the desired reproducible powder characteristics with tight control over particle size and moisture content. A solution step prior to drying assures homogeneity and minimizes dependence on the physical form of the components. Novel low-dose filling and packaging technology reproducibly meters milligram quantities of microfine powder to meet stringent quality requirements for dose control. The technology for accurate, uniform, high-throughput metering of drug powders allows for automation and is scaleable for commercial operations. Finally, the mechanical device design provides powder deagglomeration and dispersion processes in a reusable dry powder inhaler with unique characteristics. The device was designed to rely on patient-generated compressed air as the energy source. A sonic discharge of air through the novel TransJector reproducibly extracts, deagglomerates, and disperses the inhalation powder. A clear holding (spacer-type) chamber allows for patient feedback via dose visualization, and separates powder dispersal from the inspiratory effort. The EXUBERA [Pfizer (New York, NY) and sanofi-aventis (Paris, France)] product provides insulin into the bloodstream with similar reproducibly and effectiveness as subcutaneous injections.

Enteral stenting in 21 patients with malignant gastroduodenal obstruction.

Placement of an enteral stent is emerging as an effective alternative to surgery for symptomatic relief in patients with malignant gastric outflow and duodenal obstruction. We report experience in a series of patients who had the Wallstent enteral prosthesis inserted. 21 consecutive patients with inoperable obstruction, median age 75 years, had twenty-three procedures for insertion of the Wallstent under fluoroscopic guidance. Stent implantation was successful in 18 patients (86%), all of whom gained relief from nausea and vomiting. There were no short-term complications. Median survival after the procedure was four months (longest ten months), and no deaths were related to insertion. The efficacy and lack of complications in this series support use of the endoscopically placed stent for palliative management of malignant upper gastrointestinal obstruction.
