Abstract
OBJECTIVES We assessed the diagnostic yield and costs of an electrocardiogram-based national screening programme in elite cricket players and the incremental value of transthoracic echocardiography and periodic evaluation. DESIGN Cross-sectional study. METHODS Between 2008 and 2019, 1208 cricketers underwent screening with a health questionnaire, 12-lead electrocardiogram and cardiology consultation. Athletes with concerning findings underwent on-site transthoracic echocardiography and further investigations as necessary. In addition, despite a normal health questionnaire and electrocardiogram, 342 (28.3%) athletes had a transthoracic echocardiogram and 493 (40.8%) underwent repeat evaluations. RESULTS After initial evaluation, 47 (3.9%) athletes underwent on-site transthoracic echocardiography of whom 35 (2.8%) were referred for further evaluation. Four athletes (0.3%) were diagnosed with major cardiac conditions; hypertrophic cardiomyopathy (n = 1), arrhythmogenic cardiomyopathy (n = 1) and Wolff-Parkinson-White pattern (n = 2). Two athletes were identified with minor valvular abnormalities. Repeat evaluation of 493 athletes identified hypertrophic cardiomyopathy in a 22-year-old athlete, two years after his initial normal screening. During a follow-up of 5.8 ± 2.9 years no additional diagnoses or adverse cardiac events were reported. The cost of the electrocardiogram-based programme was £127,844, translating to £106 per athlete and £25,569 per major cardiac condition identified.Routine transthoracic echocardiography in 342 athletes identified two athletes with major cardiac conditions (bicuspid aortic valve with severe aortopathy and aortic regurgitation and an atrial septal defect associated with right ventricular volume overload) and 10 athletes with minor abnormalities. CONCLUSIONS An electrocardiogram-based national screening programme identified a major cardiac condition in 0.3% of athletes. Routine transthoracic echocardiography and periodic evaluation increased the diagnostic yield to 0.6%, at an incremental cost.

Abstract
BACKGROUND Racial inequities for patients with heart failure (HF) have been widely documented. HF patients who receive cardiology care during a hospital admission have better outcomes. It is unknown whether there are differences in admission to a cardiology or general medicine service by race. This study examined the relationship between race and admission service, and its effect on 30-day readmission and mortality Methods: We performed a retrospective cohort study from September 2008 to November 2017 at a single large urban academic referral center of all patients self-referred to the emergency department and admitted to either the cardiology or general medicine service with a principal diagnosis of HF, who self-identified as white, black, or Latinx. We used multivariable generalized estimating equation models to assess the relationship between race and admission to the cardiology service. We used Cox regression to assess the association between race, admission service, and 30-day readmission and mortality. RESULTS Among 1967 unique patients (66.7% white, 23.6% black, and 9.7% Latinx), black and Latinx patients had lower rates of admission to the cardiology service than white patients (adjusted rate ratio, 0.91; 95% CI, 0.84-0.98, for black; adjusted rate ratio, 0.83; 95% CI, 0.72-0.97 for Latinx). Female sex and age >75 years were also independently associated with lower rates of admission to the cardiology service. Admission to the cardiology service was independently associated with decreased readmission within 30 days, independent of race. CONCLUSIONS Black and Latinx patients were less likely to be admitted to cardiology for HF care. This inequity may, in part, drive racial inequities in HF outcomes.

Abstract
We report the case of acute painless monocular loss of vision in a 53-year-old man. An interdisciplinary etiological evaluation remained without pathological findings with respect to arterial branch occlusion. A reevaluation of the patient history led to a possible association with the administration of phosphodiesterase type 5 inhibitor (PDE5 inhibitor). A critical review of the literature on PDE5 inhibitor administration with ocular participation was performed.

Abstract
Influenza virus infections (IVI) may pose a vital threat to immunocompromised patients such as those suffering from malignancies, but specific data on epidemiology and outcome in these patients are scarce. In this study, we collected data on patients with active cancer or with a history of cancer, presenting with documented IVI in eight centres in Germany. Two hundred and three patients were identified, suffering from haematological malignancies or solid tumours; 109 (54 %) patients had active malignant disease. Influenza A was detected in 155 (77 %) and Influenza B in 46 (23 %) of patients (genera not determined in two patients). Clinical symptoms were consistent with upper respiratory tract infection in 55/203 (27 %), influenza-like illness in 82/203 (40 %), and pneumonia in 67/203 (33 %). Anti-viral treatment with oseltamivir was received by 116/195 (59 %). Superinfections occurred in 37/203 (18 %), and admission on an intensive care unit was required in 26/203 (13 %). Seventeen patients (9 %) died. Independent risk factors for death were delayed diagnosis of IVI and bacterial or fungal superinfection, but not underlying malignancy or ongoing immunosuppression. In conclusion, patients with IVI show high rates of pneumonia and mortality. Early and rapid diagnosis is essential. The high rate of pneumonia and superinfections should be taken into account when managing IVI in these patients.

Abstract
From 2006-2010, Duke University's Center for Public Genomics prepared eight case studies examining the effects of gene patent licensing practices on clinical access to genetic testing for ten clinical conditions. One of these case studies focused on the successful licensing practices employed by the University of Michigan and the Hospital for Sick Children in Toronto for patents covering the CFTR gene and its ΔF508 mutation that causes a majority of cystic fibrosis cases. Since the licensing of these patents has not impeded clinical access to genetic testing, we sought to understand how this successful licensing model was developed and whether it might be applicable to other gene patents. We interviewed four key players who either were involved in the initial discussions regarding the structure of licensing or who have recently managed the licenses and collected related documents. Important features of the licensing planning process included thoughtful consideration of potential uses of the patent; anticipation of future scientific discoveries and technological advances; engagement of relevant stakeholders, including the Cystic Fibrosis Foundation; and using separate licenses for in-house diagnostics versus kit manufacture. These features led to the development of a licensing model that has not only allowed the patent holders to avoid the controversy that has plagued other gene patents, but has also allowed research, development of new therapeutics, and wide-spread dissemination of genetic testing for cystic fibrosis. Although this licensing model may not be applicable to all gene patents, it serves as a model in which gene patent licensing can successfully enable innovation, investment in therapeutics research, and protect intellectual property while respecting the needs of patients, scientists, and public health.

Abstract
The coordination of swallowing and respiration is essential for a safe swallow. Swallowing consists of several subsecond events. To study this, it is important to use modalities with high temporal resolution. In this study, we have examined young healthy individuals with simultaneous videofluoroscopy, videomanometry and respiratory recording, all with high temporal resolution. The onset of 13 predetermined swallowing and respiratory events and the surrounding respiratory phase pattern were studied in different body positions and during different respiratory drives. An increased respiratory drive was induced by breathing 5% CO(2). The results demonstrated a highly repeatable and fixed temporal coordination of the swallowing pattern despite body position and respiratory drive. Previous studies have demonstrated a period of centrally controlled apnoea during swallowing. This apnoea period has a variable length, varying from 1 to 5 s. During increased respiratory drive, we could demonstrate a significantly shorter period of apnoea during swallowing, mainly due to an earlier resumption of respiration. The high temporal recordings in this study have revealed that swallowing during expiration is present basically in all healthy individuals. This swallowing respiratory pattern seems to be appropriate for a safe swallow. This knowledge will be used as a reference for future studies on how swallowing and respiratory coordination might be altered due to ageing and diseases.

Abstract
Molecular biological methods such as polymerase chain reaction (PCR) enable microbiologists to detect bacteria even if antibiotic treatment has already been started. Based on this case report of a 39-year-old man with multiple intracerebral lesions, we describe a PCR method called 16S rDNA-PCR which can be used to identify panbacterial DNA by focussing on the universal gene sequences for the bacterial 16S part of the ribosome.

This study investigates the effects of the male sex hormone, testosterone (Te), on self-healing of Plasmodium chabaudi malaria as well as on protein expression and functional properties of total spleen cells and splenic T cells in females of the mouse strain C57BL/10. About 90% of the B10 females survive a challenge with 10(6) P. chabaudi-infected erythrocytes. The percentage of self-healers, however, is reduced to about 60%, 40%, and 0% after pretreatment with Te for 1, 2, and 3 weeks, respectively. The progressive loss of the capability of self-healing is correlated with an increasing expression of five proteins in splenic non-T cells as revealed by two-dimensional fluorography after metabolic labelling of total spleen cells and T cells with [35S]methionine. These have molecular masses (isoelectric points) of about 10 kDa (pI 5.7), 14 kDa (pI 6.3), 14 kDa (pI 6.4), 38 kDa (pI 6.5), and 46 kDa (pI 5.5), respectively. Splenic non-T cells from mice treated with Te for 3 weeks have gained an increased capability to stimulate the concanavalin A-induced proliferative response of T cells. Te induces the changes in functional properties and protein expression of splenic non-T cells only in vivo and not in vitro. This suggests that the changes in splenic non-T cells as well as the prevention of self-healing P. chabaudi malaria are not directly induced by Te but rather indirectly, i.e. by a Te metabolite and/or Te-induced factor(s).
