Effectiveness of cloth face masks to prevent viral spread: a meta-analysis.

BACKGROUND: The effectiveness of cloth face masks to prevent viral spread has not yet been conclusively established. In this meta-analysis, we evaluate their effectiveness in comparison to standard medical/surgical and N95-typed masks against viral spread. METHODS: We identified literature through a systematic search in three databases and meta-analytically synthesized relevant studies by means of random-effects as well as multilevel modelling. RESULTS: Twelve studies comprising k = 28 effect sizes (N = 338) were included. Medical/surgical and N95-typed masks outperformed cloth masks, yielding a large effect (g = 1.40). This effect remained robust when data were grouped according to comparisons with medical/surgical masks (g = 1.25) and N95-typed masks (g = 1.29). However, effects were differentiated according to mask fit, indicating reversals of signs when cloth mask effects were compared with ill-fitting medical/surgical and N95-typed masks (gs = -12.50 and - 10.90, respectively). CONCLUSIONS: Cloth face masks were found to have significantly poorer filtering performance than medical/surgical masks and N95 masks, but only if non-cloth masks were properly fitted. Our results illustrate the necessity of using well-fitting medical/surgical or N95-typed masks to prevent viral spread, although some allowance should be made in circumstances where higher compliance with cloth mask mandates are expected.

On dying alone in prison and the social responsibility of medicine: a pilot interview study of physicians caring for terminally ill incarcerated patients in Austria and the United States.

BACKGROUND: This group of physicians is difficult to reach and small in number. While studies of palliative care and end-of-life (EOL) issues in prison have increased, especially in the United States and since the coronavirus disease 2019 (COVID-19) pandemic, they are still limited due to the constraints of carrying out research in carceral contexts. At present, there is very little knowledge of the experiences of physicians providing EOL care in prisons. The aim of this pilot study was to examine the experiences of doctors caring for terminally ill patients inside prisons. METHODS: Three expert qualitative interviews were conducted in March and April 2021 with physicians working in carceral institutions in New York State and Austria. The interviews were audio-recorded and transcribed verbatim. Braun and Clarke's thematic analysis was used to examine the data. RESULTS: The following five themes were found: (I) a lack of training and support; (II) interrupted relationships; (III) limitations on visits and saying one's goodbyes; (IV) security as a main concern; and (V) the possibility of release. CONCLUSIONS: The study reveals the difficulties physicians face when caring for dying incarcerated patients. Provider-patient relationships are hardly continuous. The findings represent a starting point for further research. Support from the medical and palliative care community is needed for adequate provision of EOL care within prisons, improved post-release conditions, and help for physicians working in existing structures.

Routine laboratory parameters to support decision on parenteral nutrition in palliative care.

Introduction: Parenteral nutrition (PN) is widely used in palliative care (PC), but there is limited evidence to support its use at the end of life (EOL). This aim of this was to investigate the relationship between routine laboratory parameters and survival in patients receiving PN, and to develop a decision tree model to support clinicians decide whether to start or forgo PN. Methods: The laboratory parameters of 113 patients with advanced diseases who were admitted to a specialized palliative care unit (PCU) were analyzed at two points in time: T0 = before PN, T1 = two weeks after initiation of PN. Univariate Mann-Whitney U-tests and multivariate linear regression models, as well as a decision tree analysis were computed; all in relation to survival time. Results: The final regression model was significant with p = 0.001 (adjusted R2 = 0.15) and included two predictors for survival time after PN initiation: the CRP/albumin ratio and urea at T1 (ps = 0.019). Decision tree analysis revealed three important predictors for classification of survival time after PN initiation: CRP, urea, and LDH (all at T0). Discussion: The decision tree model may help to identify patients likely to benefit from PN, thus supporting the clinical decision whether or not to start PN.

The impact of COVID-19 and socioeconomic status on psychological distress in cancer patients.

Objective: We aimed to investigate the impact of the COVID-19 pandemic on psychological symptom burden against the socioeconomic background of cancer patients using data from routine assessments before and during the pandemic. Method: In this cross-sectional study, standardised assessment instruments were applied in N = 1,329 patients to screen for symptoms of anxiety, depression, post-traumatic stress, and fatigue from 2018 to 2022. Two MANOVAs with post-hoc tests were computed. First, only time was included as predictor to examine the isolated impact of the pandemic. Second, income level and education level were included as further predictors to additionally test the predictive power of socioeconomic factors. Results: In the final model, only income had a significant impact on all aspects of psychological symptom burden, with patients with low income being highly burdened (partial η² = .01, p = .023). The highest mean difference was found for depressive symptoms (MD = 0.13, CI = [0.07; 0.19], p < .001). The pandemic had no further influence on psychological distress. Conclusions: Although the pandemic is a major stressor in many respects, poverty may be the more important risk factor for psychological symptom burden in cancer outpatients, outweighing the impact of the pandemic.

Statements of Austrian hospices and palliative care units after the implementation of the law on assisted suicide : A qualitative study of web-based publications.

BACKGROUND: Since January 2022, assisted suicide (AS) in Austria is legal under certain conditions. One of these conditions is informative consultations with two physicians, one of whom must be qualified in palliative medicine. Patients who are thinking about AS can approach palliative care institutions. This study aims to assess the availability and nature of Austrian palliative care institutions' web-based statements about AS. METHODS: In this qualitative study, the websites of all Austrian palliative care units (n = 43) and all Austrian inpatient hospices (n = 14) were searched for possible statements on AS once in February 2022 and once in August 2022 using the three search terms "suicide", "assisted", and "euthanasia". The findings were subsequently evaluated using thematic analysis and NVivo software. RESULTS: Statements or texts that included positions on AS were found on the websites of 11 institutions (19%). The results covered three main themes 1) demarcation: denial of involvement and judgment about AS, 2) duty: handling of requests and describing the target group of care recipients, and 3) explanation: experience, values, concerns, and demands. CONCLUSION: The results of this study indicate that people in Austria who wish to have AS and who may use the internet as their first source of information largely find no relevant information. There is no online statement of a palliative care or hospice institution that endorses AS. Positions on AS are mostly lacking, while reluctant attitudes of Christian institutions are predominant.

The potential of medical comics to teach palliative care skills: a cross-sectional study of 668 medical students.

BACKGROUND: Palliative care (PC) skills are important when caring for patients with advanced illness in a broad range of settings. Students need to be trained in communication and empathy, both representing essential PC skills. Therefore, creative approaches could promote the understanding of relevant PC skills. METHODS: In an online lecture about graphic medicine, different medical comics (MC) were used to introduce the field of graphic medicine and to illustrate relevant skills in PC. After the lecture, an online survey was conducted. The survey consisted of each respondent`s sociodemographic profile and a questionnaire on multiple aspects related to the field of MC. Spearman correlation coefficients and Cohen's effect sizes were used for statistical analysis. RESULTS: The survey respondents comprised 668 students, 337 female, 326 male and 5 diverse. The results showed that the students had never (27.2%) or had very rarely (31.9%) been involved in with the field of MC. The largest number would rate their interest as somewhat or very interested (58.8%). When considering the use of MC to understand different perspectives, the students mainly rated them as useful (54.6%) or very useful (23.4%). Women had a more positive attitude towards MC than men (P<0.001). Students who placed more importance on PC skills were more likely to recommend the use of MC in general medical education (r=0.11, P=0.005). The majority of the students (58.8%) moderately or strongly agreed on the use of MC as a teaching method in PC. CONCLUSIONS: After a single lecture on graphic medicine, the students were positive about using MC for teaching PC skills. Since the lecture was short and the majority of the medical students stated that they had not been previously exposed to the field of MC, this study demonstrates that it is promising to further use and evaluate a set of visual and narrative illustrations as a teaching method in PC.

Kidney Function Worsening Is Linked to Parenteral-Nutrition-Dependent Survival in Palliative Care Patients.

BACKGROUND: Parenteral nutrition (PN) is frequently administered in palliative care patients suffering from cachexia. The evidence regarding the use of PN in terminally ill patients is scarce. Routine laboratory parameters might help to decide whether to start or forgo PN, which could decrease overtreatment at the end of life. Kidney failure was frequently associated with survival. However, a relation between kidney function parameters and parenteral nutrition has not been observed thus far. The aim of this retrospective cohort study was to analyze kidney function parameters in palliative care patients under PN, as well as the relation between these parameters and overall survival. METHODS: Patients who were admitted to the Department of Palliative Medicine at the Medical University of Vienna were screened for PN treatment. Whether kidney function parameters at baseline or their dynamics over the course of two weeks were associated with survival was assessed with descriptive and interferential statistics. RESULTS: In total, 113 of 443 palliative care patients were administered parenteral nutrition for the first time. The overall survival (OS) for all patients with increased kidney function parameters at baseline was lower (creatinine: hazard ratio (HR) = 1.808, p < 0.001; urea: HR = 1.033, p < 0.001; uric acid HR = 1.055, p = 0.015). No significant increase in creatinine blood levels was observed in the first 2 weeks after the initiation of PN when compared to the non-PN group (p = 0.86). However, if creatinine blood levels increased within the PN group, lower overall survival was found (HR = 2.046, p = 0.007). CONCLUSION: Increased kidney function parameters, such as creatinine, urea and uric acid, might be used as negative prognostic markers in palliative care patients under PN. Moreover, an increase in creatinine during the administration of parenteral nutrition in the first 2 weeks is linked to worse outcomes. These findings may help future studies to establish objective markers for clinicians to determine whether to start or end PN in palliative cancer patients and decrease potential overtreatment at the end of life.

C-reactive protein and white blood cell count are adverse prognostic markers for patients with advanced cancer on parenteral nutrition in a palliative care unit setting: A retrospective cohort study.

BACKGROUND: Parenteral nutrition is controversial in patients with advanced cancer. Nevertheless, this treatment is common practice near the end of life. AIM: We aimed to identify factors which were associated with the outcome of patients on parenteral nutrition at an academic tertiary palliative care unit. DESIGN: In this retrospective cohort study patients were assigned to two groups according to parenteral nutrition treatment. Inferential statistics were used to assess whether the dynamics of laboratory variables over 2 weeks of parenteral nutrition were associated with survival. SETTING/PARTICIPANTS: Patients admitted to the Department of Palliative Medicine at the Medical University of Vienna between 2016 and 2018 were included in this study. RESULTS: Of 443 patients, 113 patients received parenteral nutrition. Patients had a lower body mass index, lower levels of bilirubin, γ-glutamyltransferase, alkaline phosphatase, and were of younger age compared to patients which did not receive parenteral nutrition. No difference in survival as measured from admission to death was found when comparing the two groups. Levels for γ-glutamyltransferase, alkaline phosphatase, and C-reactive protein significantly increased during 2 weeks of parenteral nutrition. Among patients with parenteral nutrition, an increase in C-reactive protein or white blood cell count levels was associated with lower survival. CONCLUSION: Patients who responded with an increase of C-reactive protein or white blood cell count during 2 weeks after reinitiation or start of parenteral nutrition had a worse survival. Our findings might support clinicians and patients in their decision to forgo parenteral nutrition in a palliative care setting.
