Abstract
Background
A variety of prediction models concerning COVID-19 have been proposed since onset of the pandemic, but to this date no gold standard exists. Mortality rates show a sharp increase with advancing age but with the large heterogeneity of this population in terms of comorbidities, vulnerability and disabilities, identifying risk factors is difficult. Therefore, we aimed to research the multidimensional concept of frailty, measured by the Acute Presenting Older Patient (APOP)-screener, as a risk factor for in-hospital mortality in older COVID-19 patients.

Methods
All consecutive patients of 70 years or older, with a PCR confirmed COVID-19 infection and a completed APOP-score, presenting at the Emergency Department (ED) of the Jeroen Bosch Hospital, the Netherlands, between February 27th 2020 and February 1st 2021 were retrospectively included. We gathered baseline characteristics and scored the CCI and CFS from patient records. The primary outcome was in-hospital mortality.

Results
A total of 292 patients met the inclusion criteria. Approximately half of the patients were considered frail by the APOP or CFS. 127 patients (43.5%) scored frail on the CFS, 158 (54.1%) scored high risk on the APOP-screener. 79 patients (27.1%) died during their hospital admission. The APOP-screener showed a significantly elevated risk of in-hospital mortality when patients scored both high risk of functional and evidence of cognitive impairment (OR 2.24, 95% 1.18–4.25). Significant elevation of in-hospital mortality was found for the high CCI-scores (≥ 5)(OR 1.78, 95% 1.02–3.11), but not for the highest CFS category (5–9, frail) (OR 1.35, 95% 0.75–2.47). The discriminatory performance of the APOP, CFS and CCI were comparable (AUC resp. 0.59 (0.52–0.66), 0.54 (0.46–0.62) and 0.58 (0.51–0.65)).

Conclusion
Although the elevated risk for in-hospital mortality found for the most frail patients as scored by the APOP, this instrument has poor discriminatory value. Additionally, the CFS did not show significance in predicting in-hospital mortality and had a poor discriminatory value as well. Therefore, treatment decisions based on frailty or comorbidities alone should be made with caution. Approaching the heterogeneity of the older population by adding frailty as assessed by the APOP-score to existing prediction models may enhance the predictive value of these models.

Published: July 2022

Abstract
Background
To investigate the maximum tolerated dose (MTD) of apatinib delivered during and after intensity-modulated radiotherapy (IMRT) for unresectable hepatocellular carcinoma (HCC).

Methods
Patients with unresectable HCC who were not eligible for radiofrequency ablation (RFA), transcatheter arterial chemoembolization (TACE), or residual/ recurrent after the prior local treatment were enrolled. Patients were scheduled to be treated with IMRT at 50–60 Gy/25–30 fractions. Oral apatinib tablets were administered concurrently with IMRT and continued thereafter. We used a 3 + 3 dose-escalation design, with three dose levels of apatinib (250, 500, and 750 mg). Grade 3 or more severe adverse events (AEs) were defined as dose-limiting toxicities (DLTs). The treatment response was calculated using the Modified Response Evaluation Criteria in Solid Tumours.

Results
Nine patients with Barcelona Clinic Liver Cancer Stage C were included. One patient withdrew from the apatinib 250 mg group and another patient was added. No DLTs occurred in the apatinib 250 mg group. Five patients were included in the apatinib 500 mg group, and 2 cases of DLT (grade 3 leukopenia) were found among them. Dose escalation was terminated and the MTD was determined to be 250 mg. Common grade 1–2 AEs included fatigue, hypertension, dizziness, bone marrow suppression, and hyperbilirubinemia. The median follow-up time for all patients was 16.0 months. Three patients achieved complete response and another three achieved partial response. The objective response rate was 6/9 (66.7%), and the disease control rate was 9/9 (100%). Three patients relapsed out of the radiation field. The median progression-free survival was 17.0 months, and the median overall survival was 16.7 months.

Conclusions
When combined with IMRT, apatinib 250 mg daily was recommended for a phase 2 study of unresectable HCC. The antitumor activity of the combination treatment was encouraging. The safety and efficacy of apatinib combined with IMRT for unresectable HCC should be further investigated in future studies.

Public procurement of antineoplastic agents used for treating breast cancer in Brazil between 2013 and 2019
Authors: dos Santos Ranailla Lima Bandeira , Pepe Vera Lúcia Edais , Osorio-de-Castro Claudia Garcia Serpa 
Published: July 2022

Abstract
Background
Breast cancer is the most common cancer among women in Brazil and the country’s public health care system is the main care provider. Timely treatment can increase the chance of cure, prevent metastasis and improve quality of life. Effective public procurement of antineoplastic agents can therefore improve access to drug therapy. This study investigates patterns in the procurement of selected antineoplastic agents used for treating breast cancer by public bodies and avoidable expenditure on these drugs between January 2013 and December 2019.

Methods
We selected antineoplastic agents used for adjuvant or preoperative chemotherapy listed in the 2018 Breast Cancer Diagnosis and Treatment Guidelines and included in category L of the WHO Anatomical Therapeutic Chemical classification system. We analyzed regular purchases of antineoplastic agents registered in the Integrated General Services Administration System (SIASG), considering purchased quantity, unit price, date of purchase and procuring entity. Prices were inflation-adjusted to July 2019 based on the National Consumer Price Index.

Results
A total of 10 antineoplastic agents were selected. Trastuzumab and tamoxifen accounted for the largest share of total spending and largest volume of purchases, respectively. The Ministry of Education was the largest purchaser in volume terms of all the drugs studied, except trastuzumab 440 mg, where the category “Other Institutions” accounted for most purchases, and vinorelbine 20 mg, where the Ministry of Health made most purchases. The category “Other Institutions” accounted for the largest share of total spending. Total avoidable expenditure was R$99,130,645. Prices paid for medicines and avoidable expenditure were highest in the Ministry of Defense.

Conclusions
The differences observed in the performance of different categories of buyers as to amounts purchased and prices practiced for antineoplastic agents could be reduced by employing strategies to expand the centralization of purchases, resulting in expanded access to breast cancer medicines in the public sector.

Abstract
Background
Cancer is a frightening disease. Therefore, the care of cancer patients is very complex. This study aimed to investigate the effect of the education based on Orem’s self-care model on self-care abilities of the patients undergoing chemotherapy in Shafa Hospital in Ahvaz city, Iran.

Methods
This randomized clinical trial was carried out in 2018 on 100 cancer patients undergoing chemotherapy, who referred to Shafa Hospital in Ahvaz city, Iran. The sampling method was simple and the subjects were randomly divided into two experimental and control groups (50 in the experimental and 50 in the control group). The study outcome was the self-care ability of the patients measured before and 2 months after the intervention by the control and experimental groups. The educational intervention consisted of five 60-minute sessions (one session per week) held as educational and counseling ones through group, face-to-face and individual training based on the identified needs of the patients in the experimental group at Shafa Hospital Chemotherapy Department. To collect data, two questionnaires [the assess and identify the conceptual pattern of Orem questionnaire and the Self-care capacity assessment (ESCI)]were used. Statistical data were entered into SPSS software version 20 and analyzed by chi-square, independent t-test and paired t-test.

Results
The mean and standard deviation of age was 35.06 ± 14.51 in the control group and 31.72 ± 15.01 in the experimental group. The results of the independent t-test showed that before the educational intervention, there was no significant difference between the two groups in terms of the mean self-care (P = 0.38). But after the intervention, a significant difference was found between the mean self-care scores of the experimental and control groups (P = 0.001).

Conclusion
Application of Orem’s self-care model led to increased self-care ability of the cancer patients undergoing chemotherapy. Therefore, it is recommended that this model be included in the routine programs of chemotherapy departments.

Authors: Guven Soner 
Published: July 2022

Abstract
Background
To determine the repeatability of corneal topography measurements in severe dry eye disease (DED). A comparison of corneal topography parameters between severe DED and healthy subjects was a secondary goal of this study.

Methods
Sixty-nine patients with severe DED and 46 healthy subjects were enrolled in the study. All participants underwent repeated corneal topography measurements with Pentacam (Oculus, Germany) within a half hour time. Both eyes of the participants were used in statistical analysis. A further subcategorization of severe DED patients was performed according to Ocular Surface Disease Index (OSDI) scores: 32–50, 51–70 and 71–100. The repeatability of corneal parameters was assessed with correlation coefficients (CC).

Results
The mean age of dry eye patients and healthy subjects were 40.8 ± 13.2 (17–66) and 39.8 ± 8.2 (18–61) years (p:0.604) respectively. No significant differences were found between severe DED and control groups according to analysed corneal parameters in both eyes (p:>0.05). All CCs were greater than 0.9 in severe DED group (p:<0.001). All CCs were also greater than 0.9 in severe DED patients among different OSDI groups (p:<0.001).

Conclusions
Corneal topography measurements are highly repeatable in severe DED with Pentacam. This is the first report about this topic. Nonetheless, further studies are needed with different topography devices for validation.

Authors: Akinyemi Patrick A. , Afolabi Olusegun T. , Aluko Olufemi O. 
Published: July 2022

Abstract
Background
Household water security encompasses water-related factors that pose threats to public health at the household level. It presents a reliable access to water in sufficient quantity and quality towards meeting basic human needs. This study assessed the dynamics of seasonal variations in household water security and the association between household water security and diarrheal disease across dry and wet seasons in an urban settlement in Southwest Nigeria.

Methods
A panel study design was employed to study 180 households selected using a multistage sampling technique. The selected households were studied during dry and rainy seasons. Household water security was assessed through the application of the all or none principle to 9 indicators associated with household water security. The intensity of water insecurity was also assessed using the nine indicators. The higher the number of indicators a household failed, the higher the intensity of household water insecurity. The association between the intensity of household water insecurity and the burden of diarrheal disease across the seasons was assessed using the Mantel-Haenszel test.

Results
No household was water-secure in both dry and rainy seasons; however, the intensity of insecurity was more pronounced during the dry season compared with the rainy season. Ninety households (52.0%), had water insecurity intensity scores above fifty percentiles during the dry season while 21 (12.1%) households had a water insecurity score above the 50th percentile during raining season, p < 0.001. The burden of diarrheal disease was significantly higher among households with a water insecurity intensity score above the 50th percentile, 9 (8.1%) compared to households with a water insecurity intensity score below the 50th percentile 7 (3.0%), p = 0.034.
There was no statistically significant association between the intensity of water insecurity and diarrheal disease burden across the dry and rainy seasons, p = 0.218.

Conclusion
The high burden of household water insecurity deserves concerted efforts from all concerned stakeholders, a panacea to an important health threat in the developing world.

Published: July 2022

Abstract
Background
COVID-19 has caused over 305 million infections and nearly 5.5 million deaths globally. With complete eradication unlikely, organizations will need to evaluate their risk and the benefits of mitigation strategies, including the effects of regular asymptomatic testing. We developed a web application and R package that provides estimates and visualizations to aid the assessment of organizational infection risk and testing benefits to facilitate decision-making, which combines internal and community information with malleable assumptions.

Results
Our web application, covidscreen, presents estimated values of risk metrics in an intuitive graphical format. It shows the current expected number of active, primarily community-acquired infections among employees in an organization. It calculates and explains the absolute and relative risk reduction of an intervention, relative to the baseline scenario, and shows the value of testing vaccinated and unvaccinated employees. In addition, the web interface allows users to profile risk over a chosen range of input values. The performance and output are illustrated using simulations and a real-world example from the employee testing program of a pediatric oncology specialty hospital.

Conclusions
As the COVID-19 pandemic continues to evolve, covidscreen can assist organizations in making informed decisions about whether to incorporate covid test based screening as part of their on-campus risk-mitigation strategy. The web application, R package, and source code are freely available online (see “Availability of data and materials”).
Use data augmentation for a deep learning classification model with chest X-ray clinical imaging featuring coal workers' pneumoconiosis
Authors: Dong Hantian , Zhu Biaokai , Zhang Xinri , Kong Xiaomei 
Published: July 2022

Abstract
Purpose
This paper aims to develop a successful deep learning model with data augmentation technique to discover the clinical uniqueness of chest X-ray imaging features of coal workers' pneumoconiosis (CWP).

Patients and methods
We enrolled 149 CWP patients and 68 dust-exposure workers for a prospective cohort observational study between August 2021 and December 2021 at First Hospital of Shanxi Medical University. Two hundred seventeen chest X-ray images were collected for this study, obtaining reliable diagnostic results through the radiologists' team, and confirming clinical imaging features. We segmented regions of interest with diagnosis reports, then classified them into three categories. To identify these clinical features, we developed a deep learning model (ShuffleNet V2-ECA Net) with data augmentation through performances of different deep learning models by assessment with Receiver Operation Characteristics (ROC) curve and area under the curve (AUC), accuracy (ACC), and Loss curves.

Results
We selected the ShuffleNet V2-ECA Net as the optimal model. The average AUC of this model was 0.98, and all classifications of clinical imaging features had an AUC above 0.95.

Conclusion
We performed a study on a small dataset to classify the chest X-ray clinical imaging features of pneumoconiosis using a deep learning technique. A deep learning model of ShuffleNet V2 and ECA-Net was successfully constructed using data augmentation, which achieved an average accuracy of 98%. This method uncovered the uniqueness of the chest X-ray imaging features of CWP, thus supplying additional reference material for clinical application.
Effect of body mass index on symptomatic venous thromboembolism and prosthesis revision risk after total knee arthroplasty: a long-term study from China
Authors: Shao Changjie , Xu Kuishuai , Zhang Liang , Yu Tengbo , Yu Ning 
Published: July 2022

Abstract
Objective
To investigate the effect of body mass index (BMI) on the risk of symptomatic VTE and prosthesis revision after total knee arthroplasty (TKA).

Methods
Seven thousand one hundred eighty-two patients with primary unilateral TKA treated in our hospital from 2011 to 2020 were divided into four groups according to BMI: BMI < 25 kg/m2, BMI 25 kg/m2–29.9 kg/m2, BMI 30 kg/m2–34.9 kg/m2 and BMI ≥ 35 kg/m2. Incidence, Odds ratio and Kaplan-Meier survival analysis were used to evaluate the effects of BMI on symptomatic VTE and prosthesis revision risk after TKA.

Results
The incidence of VTE after TKA was 8.9‰(64/7182). There was no significant difference in the incidence of VTE among different BMI groups(P = 0.452). Deep vein thrombosis mainly occurred in the distal lower extremities, especially in intermuscular veins. Revision rate of prosthesis after TKA was 6.4‰(46/7182). There was no significant difference in revision rate among different BMI groups(P = 0.718). In the univariate analysis of TKA, compared with patients with normal BMI, the risk of postoperative VTE and prosthesis revision in patients with overweight, obesity class I and obesity class II did not increase. Higher prosthesis revision rate and lower prosthesis survival rate were observed in BMI ≥ 35 kg/m2 group, although the difference was not statistically significant.

Conclusions
Through such a retrospective large sample data of long-term follow-up, we believe that the higher BMI was not associated with the increased risk of symptomatic VTE and prosthesis revision after TKA. When TKA was used for appropriate indications, high BMI should not be considered as a contraindication.
Interdisciplinary staff perceptions of advance care planning in long-term care homes: a qualitative study
Authors: Vellani Shirin , Green Elizabeth , Kulasegaram Pereya , Sussman Tamara , Wickson-Griffiths Abby , Kaasalainen Sharon 
Published: July 2022

Abstract
Background
Residents living in long-term care homes (LTCH) have complex care needs, multiple chronic conditions, increasing frailty and cognitive impairment. A palliative approach that incorporates advance care planning (ACP) should be integrated with chronic disease management, yet it is not a norm in most LTCHs. Despite its growing need, there remains a lack of staff engagement in the ACP process.

Objectives
The aim of this study was to explore the perceptions and experiences of interdisciplinary staff related to the practice of ACP in LTCHs.

Methods
This study is part of a larger Canadian project, iCAN ACP, that aims to increase uptake, and access to ACP for older Canadians living with frailty. An exploratory qualitative design using an interpretive descriptive approach was employed utilizing focus groups and semi-structured interviews with staff from four LTCHs in Ontario, Canada.

Findings
There were 98 participants, including nurses (n = 36), physicians (n = 4), personal support workers (n = 34), support staff (n = 23), and a public guardian (n = 1). Three common themes and nine subthemes were derived: a) ongoing nature of ACP; b) complexities around ACP conversations; and c) aspirations for ACP becoming a standard of care in LTCHs.

Discussion
The findings of this study provide important contributions to our understanding of the complexities surrounding ACP implementation as a standard of practice in LTCHs. One of the critical findings relates to a lack of ACP conversations prior to admission in the LTCHs, by which time many residents may have already lost cognitive abilities to engage in these discussions. The hierarchical nature of LTCH staffing also serves as a barrier to the interdisciplinary collaboration required for a successful implementation of ACP initiatives. Participants within our study expressed support for ACP communication and the need for open lines of formal and informal interdisciplinary communication. There is a need for revitalizing care in LTCHs through interdisciplinary care practices, clarification of role descriptions, optimized staffing, capacity building of each category of staff and commitment from the LTCH leadership for such care.

Conclusion
The findings build on a growing body of research illustrating the need to improve staff engagement in ACP communication in LTCHs.

Published: July 2022

Abstract
Background and aims
The Healthy Beverage Index (HBI) is a valuable technique to estimate the synergistic effects of overall beverage consumption. Several studies have evaluated the associations between HBI and beneficial changes in the health status. however, there is no study on the association between patterns of beverage consumption and mental health status. Therefore, this study sought to examine the association between HBI and psychological disorders among overweight and obese women.

Methods
199 overweight and obese women, between the ages of 18 and 55 y, were enrolled in this cross-sectional study in Tehran, Iran. To collect beverage dietary data, a validated semi-quantitative food-frequency questionnaire (FFQ) was used. Furthermore, the DASS-21 questionnaire was used to assess psychological profile states.

Results
The association of total depression anxiety stress (DASS) score with healthy beverage index (HBI) tertiles in models was marginally significant (OR =: 0.78; 95% CI 0.30–2.02; P-value = 0.074; (OR = 0.77; 95% CI 0.28–2.16; P-value = 0.062), respectively. In terms of stress, anxiety, and depression, after adjusting for confounders, participants with higher HBI in the third tertile had lower odds of depression vs. the first tertile (OR = 0.99; 95% CI 0.35–2.81; P-trend = 0.040).

Conclusion
We demonstrate that the total DASS score was associated with HBI tertiles. We also found that participants with higher HBI had lower odds of depression. However, additional well-designed studies are needed to confirm the veracity of these findings.
