Anaemia is independently associated with mortality in patients with hepatocellular carcinoma.

BACKGROUND: Anaemia is frequent in patients with cancer and/or liver cirrhosis and is associated with impaired quality of life. Here, we investigated the impact of anaemia on overall survival (OS) and clinical characteristics in patients with hepatocellular carcinoma (HCC). MATERIALS AND METHODS: HCC patients treated between 1992 and 2018 at the Medical University of Vienna were retrospectively analysed. Anaemia was defined as haemoglobin level <13 g/dl in men and <12 g/dl in women. RESULTS: Of 1262 assessable patients, 555 (44.0%) had anaemia. The main aetiologies of HCC were alcohol-related liver disease (n = 502; 39.8%) and chronic hepatitis C (n = 375; 29.7%). Anaemia was significantly associated with impaired liver function, portal hypertension, more advanced Barcelona Clinic Liver Cancer stage and elevated C-reactive protein (CRP). In univariable analysis, anaemia was significantly associated with shorter median OS [9.5 months, 95% confidence interval (95% CI) 7.3-11.6 months] versus patients without anaemia (21.5 months, 95% CI 18.3-24.7 months) (P < 0.001). In multivariable analysis adjusted for age, Model for End-stage Liver Disease, number of tumour nodules, size of the largest nodule, macrovascular invasion, extrahepatic spread, first treatment line, alpha-fetoprotein and CRP, anaemia remained an independent predictor of mortality (adjusted hazard ratio 1.23, 95% CI 1.06-1.43, P = 0.006). CONCLUSIONS: Anaemia was significantly associated with mortality in HCC patients, independent of established liver- and tumour-related prognostic factors. Whether adequate management of anaemia can improve outcome of HCC patients needs further evaluation.

Evaluating the effects of minimum unit pricing in Scotland on the prevalence of harmful drinking: a controlled interrupted time series analysis.

OBJECTIVES: In May 2018, the Scottish Government introduced a minimum unit price (MUP) for alcohol of £0.50 (1 UK unit = 8 g ethanol) to reduce alcohol consumption, particularly among people drinking at harmful levels. This study aimed to evaluate MUP's impact on the prevalence of harmful drinking among adults in Scotland. STUDY DESIGN: This was a controlled interrupted monthly time series analysis of repeat cross-sectional data collected via 1-week drinking diaries from adult drinkers in Scotland (N = 38,674) and Northern England (N = 71,687) between January 2009 and February 2020. METHODS: The primary outcome was the proportion of drinkers consuming at harmful levels (>50 [men] or >35 [women] units in diary week). The secondary outcomes included the proportion of drinkers consuming at hazardous (≥14-50 [men] or ≥14-35 [women] units) and moderate (<14 units) levels and measures of beverage preferences and drinking patterns. Analyses also examined the prevalence of harmful drinking in key subgroups. RESULTS: There was no significant change in the proportion of drinkers consuming at harmful levels (ß = +0.6 percentage points; 95% confidence interval [CI] = -1.1, +2.3) or moderate levels (ß = +1.4 percentage points; 95% confidence interval = -1.1, +3.8) after the introduction of MUP. The proportion consuming at hazardous levels fell significantly by 3.5 percentage points (95% CI = -5.4, -1.7). There were no significant changes in other secondary outcomes or in the subgroup analyses after correction for multiple testing. CONCLUSIONS: Introducing MUP in Scotland was not associated with reductions in the proportion of drinkers consuming at harmful levels but did reduce the prevalence of hazardous drinking. This adds to previous evidence that MUP reduced overall alcohol consumption in Scotland and consumption among those drinking above moderate levels.

Stakeholder Engagement in the Development of Public Health Economic Models: An Application to Modelling of Minimum Unit Pricing of Alcohol in South Africa.

BACKGROUND: Health economic models aim to provide decision makers with information that is contextually relevant, understandable and credible. This requires ongoing engagement throughout the research project between the modeller and end-users. OBJECTIVES: We aim to reflect on how a public health economic model of minimum unit pricing of alcohol in South Africa benefited from, and was shaped by, stakeholders. We outline how engagement activities were used during the development, validation and communication phases of the research with input gathered at each stage to inform future priorities. METHODS: A stakeholder mapping exercise was completed to identify stakeholders with the required knowledge, for example academics with expertise in modelling alcohol harm in South Africa, members of civil society organisations with lived experience of informal alcohol outlets, and policy professionals working at the forefront of alcohol policy development in South Africa. The stakeholder engagement consisted of four phases: developing a detailed understanding of the local policy context; co-producing model focus and structure; scrutinising model development and communication planning; and communicating research evidence to end-users. The first phase utilised 12 individual semi-structured interviews. Phases two to four centred around face-to-face workshops (two online) with both individual and group-based exercises employed to achieve required outputs. RESULTS: Phase one provided key learning on policy context and initiated working relationships. Phases two to four provided a conceptualisation of the problem of alcohol harm in South Africa and the choice of policy to model. Stakeholders chose population subgroups of interest and advised on both economic and health outcomes. They provided input on critical assumptions, data sources, priorities for future work, and communication strategies. The final workshop provided a platform to communicate the results of the model to a largely policy audience. These activities led to the production of highly contextualised research methods and findings that were able to be communicated widely beyond academia. CONCLUSIONS: Our programme of stakeholder engagement was fully integrated into the research programme. It resulted in a number of benefits including creating positive working relationships, guiding modelling decisions, tailoring the research to the context, and providing ongoing opportunities for communication.

[Retinal manifestation in hematological diseases]. / Retinabeteiligung bei hämatologischen Erkrankungen.

Hematological diseases can lead to ocular manifestations. Retinal manifestation occurs in patients with anemia, leukemia, lymphoma, myeloproliferative and myelodysplastic syndromes. It is not uncommon for the ocular findings to be the first manifestation of the systemic disease. In these patients the correct diagnosis can be difficult because as a rule the retinal involvement is unspecific. In cases of unexplained retinal changes with hemorrhage and cotton wool spots, an underlying hematological disease should be suspected and the appropriate diagnostics should be recommended.

Interdisciplinary working in public health research: a proposed good practice checklist.

Background: Guidance on how different disciplines from the natural, behavioural and social sciences can collaborate to resolve complex public health problems is lacking. This article presents a checklist to support researchers and principle investigators to develop and implement interdisciplinary collaborations. Methods: Fourteen individuals, representing 10 disciplines, participated in in-depth interviews to explore the strengths and challenges of working together on an interdisciplinary project to identify the determinants of substance use and gambling disorders, and to make recommendations for future interdisciplinary teams. Data were analysed thematically and a checklist was derived from insights offered by participants during interview and discussion among the authors on the implications of findings. Results: Participants identified 18 scientific, interactional and structural strengths and challenges of interdisciplinary research. These findings were used to develop an 18-item BASICS checklist to support future interdisciplinary collaborations. The five domains of the checklist are: (i) Blueprint, (ii) Attitudes, (iii) Staffing, (iv) Interactions and (v) Core Science. Conclusion: Interdisciplinary work has the potential to advance public health science but the numerous challenges should not be underestimated. Use of a checklist, such as BASICS, when planning and managing projects may help future collaborations to avoid some of the common pitfalls of interdisciplinary research.

[Bilateral eye injuries by external transversal force]. / Bilaterale Augenverletzung durch transversale Gewalteinwirkung.

A 49-year-old female victim of violent crime with an acute bilateral loss of vision was referred to our hospital. The ophthalmological evaluation showed complete subconjunctival hemorrhage of both eyes, bilateral hemophthalmos and hypotonia of the left eye. These raised the suspicion of an occult scleral rupture. We immediately performed exploratory surgery and found a perforating scleral lesion of the left eye and a penetrating scleral lesion of the right eye. Furthermore, a small, cruciform wound was detected on the left temple. In cooperation with the department of radiology, the extraordinary injury pattern was reconstructed: a horizontal stab wound with perforation of the left eye and penetration of the right eye caused by a screwdriver. Visual rehabilitation necessitated further surgical interventions. Besides the intraoperative approach, immediate primary wound management within 100 h of trauma plays a pivotal role for long-term outcome.

Parental perception of child vulnerability among mothers of very low birth weight infants: psychological predictors and neurodevelopmental sequelae at 2 years.

OBJECTIVE: The objective of this study was to examine the impact of maternal psychological distress on the development of parental perception of child vulnerability (PPCV) in mothers of very low birth weight (VLBW) infants; and to examine the impact of PPCV on neurodevelopmental outcome in VLBW infants in the second year of life. STUDY DESIGN: This is a prospective study of 69 mothers and their VLBW infants recruited from 2011 to 2012 for whom maternal psychological data were collected during the neonatal intensive care unit (NICU) hospitalization. Maternal PPCV was assessed at 4 months corrected age (CA). Neurodevelopmental outcome was assessed at 20 months CA. Regression analyses modeled the development of PPCV and the impact of PPCV on neurodevelopmental outcome. RESULTS: PPCV at 4 months CA was predicted by maternal anxiety and history of previous fetal loss reported during the NICU stay. Higher PPCV at 4 months CA was associated with lower language scores at 20 months CA. CONCLUSION: Targeted interventions aimed at reducing PPCV in the NICU are supported.

Alcohol consumption after health deterioration in older adults: a mixed-methods study.

OBJECTIVE: To examine if and how older adults modify their drinking after health deterioration, and the factors that motivate changing or maintaining stable drinking behaviour. STUDY DESIGN: Explanatory follow-up mixed-methods research. METHODS: The association between health deterioration and changes in alcohol consumption was examined using secondary data from the English Longitudinal Study of Ageing, a biennial prospective cohort study of a random sample of adults aged 50 years and older living in England. Data were collected through a personal interview and self-completion questionnaire across three waves between 2004 and 2009. The sample size (response rate) across the three waves was 8781 (49.9%), 7168 (40.3%) and 6623 (37.3%). The Chi-squared test was used to examine associations between diagnosis with a long-term condition or a worsening of self-rated health (e.g. from good to fair or fair to poor) and changes in drinking frequency (e.g. everyday, 5-6 days per week, etc.) and volume (ethanol consumed on a drinking day) between successive waves. In-depth interviews with 19 older adults recently diagnosed with a long-term condition were used to explore the factors that influenced change or maintenance in alcohol consumption over time. A purposive sampling strategy was used to recruit a diverse sample of current and former drinkers from voluntary and community organizations in the north of England. An inductive approach was used to analyze the data, facilitating the development of an a posteriori framework for understanding drinking change. RESULTS: There was no significant relationship between health deterioration and changes in drinking volume over time. There was however a significant association between health deterioration and changes in drinking frequency between successive waves (χ2 = 15.24, P < 0.001 and χ2 = 17.28, P < 0.001). For example, of participants reporting health deterioration between the first two waves, 47.6% had stable drinking frequency, 23.4% increased their drinking frequency and 29% reported decreased drinking frequency. In comparison, of participants reporting no health deterioration, 52.7% reported stable frequency, 20.8% increased frequency and 26.4% decreased frequency. In qualitative interviews, older adults described a wide range of factors that influence changes in drinking behaviour: knowledge gained from talking to healthcare professionals, online and in the media; tangible negative experiences that were attributed to drinking; mood and emotions (e.g. joy); the cost of alcohol; pub closures; and changes in social roles and activities. Health was just one part of a complex mix of factors that influenced drinking among older adults. CONCLUSION: Patterns of drinking change after health deterioration in older adults are diverse, including stable, increasing and decreasing alcohol consumption over time. Although health motivations to change drinking influence behaviour in some older adults, social and financial motivations to drink are also important in later life and thus a holistic approach is required to influence behaviour.

Transsynaptic Retrograde Degeneration: Clinical Evidence with Homonymous RGCL Loss on OCT.

BACKGROUND: Retinal thinning after a retrogeniculate lesion (transsynaptic retrograde degeneration) was first described 50 years ago, but has long been a controversial issue. It is now possible to use OCT for the in vivo measurement of retinal thickness. MATERIAL AND METHODS: This was a retrospective study of patients with homonymous visual field loss, with SD-OCT assessment (RNFL and RGCL measurements) in isolated retrogeniculate lesions, subsequently confirmed by a neuroradiologist. RESULTS: Nine patients with vascular, inflammatory or tumour brain lesions were included in the study. Homonymous RGCL thinning was found in all patients, and correlated with the visual field defect. No correlation was found with RNFL. CONCLUSIONS: The homonymous defect of RGCL in patients with retrogeniculate lesions demonstrates the presence of transsynaptic retrograde degeneration. RGCL is a better predictor of visual field defects than RNFL measurement.

Which breast pump for which mother: an evidence-based approach to individualizing breast pump technology.

The majority of new mothers in the United States use breast pumps in the first 4 months postbirth in order to achieve their personal human milk feeding goals. Although these mothers seek guidance from health-care professionals with respect to the type and use of breast pumps, there are few evidence-based guidelines to guide this professional advice. This paper reviews the evidence to facilitate professional individualization of breast pump recommendations using three categories of literature: the infant as the gold standard to which the pump is compared; the degree of maternal breast pump dependency (for example, the extent to which the breast pump replaces the infant for milk removal and mammary gland stimulation); and the stage of lactation for which the pump replaces the infant. This review can also serve to inform public and private payers with respect to individualizing breast pump type to mother-infant dyad characteristics.

Percutaneous left atrial appendage occlusion for stroke prevention in atrial fibrillation: an update.

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia encountered in clinical practice. One of its most devastating complications is the development of thromboembolism leading to fatal or disabling stroke. Oral anticoagulation (OAC, warfarin) is the standard treatment for stroke prevention in patients with AF with an increased stroke risk. However, there are several obstacles to long-term OAC therapy, including the risk of serious bleeding, several drug-drug interactions and the need for frequent blood testing. Although newer oral anticoagulants have been developed, these drugs also face issues of major bleeding and non-compliance. Therefore, alternative treatment options for stroke prevention in patients with AF with a high stroke risk are needed. Percutaneous left atrial appendage (LAA) occlusion is an evolving therapy, which should be taken into consideration in those patients with non-valvular AF with a high stroke risk and contraindications for OAC. This article aims to discuss the rationale for LAA closure, the available LAA occlusion devices and their clinical evidence until now. Moreover, we discuss the importance of proper patient selection, the role of various imaging techniques and the need for a more tailored postprocedural antithrombotic therapy.

[Fever and right upper abdominal pain in a 26-year-old returning from travel abroad]. / Fieber und rechtsseitige Oberbauchschmerzen bei einem 26-jährigen Reiserückkehrer.

Persistent fever and unspecific general symptoms need a complete and detailed medical history and search for infection. We report on a case of amebiasis with liver abscesses of a 26-year-old man. He had stayed several weeks in India and South America. After being free of complaints for 4 months, unspecific general symptoms and fever appeared. Due to proven liver abscesses, a combination treatment was given. Within 12 days, he was free of symptoms and could be discharged.

Reducing necrotizing enterocolitis in very low birth weight infants using quality-improvement methods.

OBJECTIVE: Owing to a rise in necrotizing enterocolitis (NEC, stage ⩾ 2) among very low birth weight (VLBW, birth weight <1500 g) infants from 4% in 2005 to 2006 to 10% in 2007 to 2008, we developed and implemented quality improvement (QI) initiatives. The objective was to evaluate the impact of QI initiatives on NEC incidence in VLBW infants. STUDY DESIGN: In September 2009, we developed an NEC QI multidisciplinary team that conducted literature reviews and reviewed practices from other institutions to develop a feeding protocol, which was implemented in December 2009. The team tracked intervention compliance and occurrence of NEC stage ⩾ 2. In May 2010, we reviewed our nasogastric tube practice and relevant literature to develop a second intervention that reduced nasogastric tube indwelling time. The infants were divided into three groups: baseline (January 2008 to Novovember 2009, n219), QI phase 1 (December 2009 to May 2010, n62) and QI phase 2 (June 2010 to November 2011, n170). RESULT: The NEC incidence did not decrease after implementation of the feeding protocol in QI phase 1 (19.4%) but did decline significantly after changing nasogastric tube management in QI phase 2 (2.9%). Multivariable logistic regression analysis demonstrated a significant relationship between QI phase and the incidence of NEC. CONCLUSION: QI initiatives were effective in decreasing NEC incidence in our high human milk-feeding NICU. Nasogastric tube bacterial contamination may have contributed to our peak in NEC incidence.

[Firework-related eye trauma from 2005 to 2013]. / Bulbustraumata durch Feuerwerkskörper von 2005 bis 2013.

PURPOSE: Fireworks combusted during New Year's Eve festivities can cause different eye traumas which often need complex reconstructive surgery. It was our aim to systematically analyse these eye trauma cases which were treated at our clinic during the last eight years. MATERIALS AND METHODS: Age, gender, side, trauma mechanism, treatment methods and outcome were analysed for all eye trauma cases caused by fireworks during the New Year's Eve celebrations from 2006 to 2013. For statistical analysis all trauma cases were divided into two groups of major and non-major eye trauma. RESULTS: The total number of patients treated was 122 (28 women, 94 men, mean age 26.2±13.0 years) with 137 traumatised eyes (77 right, 60 left). 24.6% of patients were ≤18 years of age. 76.2% were bystanders. 50 eyes from 46 patients (37.7%) suffered from major eye trauma. 26 patients (21.3%) were hospitalised. 8 eyes (5.8%) suffered from a penetrating injury or globe rupture and underwent primary reconstructive surgery. Further 16 eyes (11.7%) suffered from major eye trauma without open globe injury. In the aftermath 11 eyes (8.0%) went blind (visual acuity<1/50). Gender, side and role of the patient were not significantly different between the two groups. Mean age was significantly higher in the major eye trauma group (p=0.01). CONCLUSION: Young male bystanders have a high risk for suffering from eye trauma caused by fireworks. However older patients suffer from major eye trauma more often. More education and prophylaxis of eye trauma caused by fireworks is desirable.

Quality indicators for human milk use in very low-birthweight infants: are we measuring what we should be measuring?

OBJECTIVE: The objective of this study was to compare the currently used human milk (HM) quality indicators that measure whether very low-birthweight (VLBW; <1500 g birthweight) infants 'ever' received HM and whether they were still receiving HM at discharge from the neonatal intensive care unit (NICU) to the actual amount and timing of HM received. STUDY DESIGN: This study used data from a large NIH-funded cohort study and calculated whether VLBW infants ever received HM (HM-Ever) and of these infants, the percentage who were still receiving HM at NICU discharge (HM-DC). Then, the HM-DC indicator (exclusive, partial and none) was compared with the amount and timing of HM feedings received by these same infants. RESULT: Of the 291 VLBW infants who met inclusion criteria, 285 received some HM (HM-Ever=98%). At NICU discharge (HM-DC), 24.2, 15.1 and 60.7% were receiving exclusive, partial and no HM, respectively. Of the 60.7% infants with no HM-DC, some had received higher amounts of HM during the NICU hospitalization than infants categorized as exclusive and partial for HM-DC. Of the infants with no HM-DC, 76.8 and 59.7% had received exclusive HM during the days 1-14 and days 1-28 exposure periods, respectively. CONCLUSION: The average daily dose (HM-DD; in ml kg(-1) d(-1)) and cumulative percentage (HM-PCT; as % of cumulative enteral intake) of HM feedings were sufficient to significantly reduce the risk of multiple morbidities, including late-onset sepsis, necrotizing enterocolitis, neurocognitive delay and rehospitalization, in the majority of the VLBW infants who were discharged with no HM-DC. Quality indicators that focus on the amount and timing of HM feedings in the NICU should be added to the HM-Ever and HM-DC measures.

[Ocular malformation and paediatric retinal detachment]. / Okuläre Malformation und Netzhautablösung im Kindesalter.

A range of posterior segment abnormalities, especially anomalies of the optic papilla, coloboma, and persistent hyperplastic primary vitreous are associated with the high risk to develop a retinal detachment. Most of these retinal detachments develop in the first and second decade of life. In most cases of retinal detachment caused by malformations, vitreoretinal surgery is indicated. Results of surgery depend on the nature of malformations. In spite of an anatomic re-attachment of the retina, in some eyes the functional results are limited. Especially in cases of severe PHPV, the aim of vitrectomy is only to prevent complications. Vitreoretinal surgery should not be performed in eyes with no light perception, without papillary light reflex, and/or with unrecordable visually evoked potential.
