Abstract
Background
Recent evidence suggests that albumin-to-Alkaline Phosphatase Ratio (AAPR) functions as a novel prognostic marker in several malignancies. However, whether it can predict the prognosis of unresectable pancreatic ductal adenocarcinoma (PDAC) remains unclear. Herein, we seek to investigate this possibility by a propensity score matching (PSM) analysis.

Methods
This was a retrospective cohort study in which 419 patients diagnosed with unresectable PDAC and receiving chemotherapy were recruited. Patients were stratified based on the cutoff value of AAPR. The PSM analysis was performed to identify 156 well-balanced patients in each group for overall survival (OS) comparison and subgroup analysis. Univariate and multivariate analyses were carried out to examine the potential of AAPR to indicate the prognosis of unresectable PDAC. The prediction performance of conventional model and combined model including AAPR was compared using the Akaike Information Criterion (AIC) and concordance index (C-index).

Results
We identified an AAPR of 0.4 to be the optimal cutoff for OS prediction. Patients with AAPR≤0.4 had significantly shorter OS compared with patients with AAPR> 0.4 (6.4 versus 9.3 months; P < 0.001). Based on the PSM cohort and entire cohort, multivariate Cox analysis revealed that high pretreatment for AAPR was an independent marker predicting favorable survival in unresectable PDAC (hazard ratio, 0.556; 95% confidence interval, 0.408 to 0.757; P < 0.001). Significant differences in OS were observed in all subgroups except for the group of patients age ≤ 60. Combined prognostic model including AAPR had lower AIC and higher C-index than conventional prognostic model.

Conclusions
Pretreatment AAPR servers as an independent prognostic indicator for patients with unresectable PDAC. Inclusion of AAPR improved the prediction performance of conventional prognostic model, potentially helping clinicians to identify patients at high risk and guide individualized treatment.

Abstract
Background
Poor compliance to highly active antiretroviral therapy (HAART) can result in the poor quality of life in children living with Human immunodeficiency virus/Acquired immunodeficiency syndrome (HIV/AIDS) because of low plasma drug concentration and the possibility of drug resistance. This study evaluates the response of caregivers for determination of adherence and the four quality of life domains in children (aged 14 years and under) on HAART.

Methods
We conducted a cross-sectional study of 188 children, each accompanied by their caregivers at Ola During Children’s Hospital and Makeni Government Hospital between September and November 2016. Adherence to HAART and Quality of life was assessed using the WHO Quality of life summary questionnaire (WHOQOL-BREF). We obtained ethical approval from the Sierra Leone Ethics and Scientific Review Committee.

Results
The study revealed 5.9% adherence amongst paediatric patients, and a strong association of adherent patients(p = 0.019*) to the physical health domain (mean = 64.61 SD = 8.1). Caregiver HIV status showed a strong association with the physical (mean = 58.3, SD = 11.7 and p = 0.024*), and psychological health domains (mean = 68.2, SD = 14.7 and p = 0.001). Caregiver type (mother/father/sibling) accompanying child to hospital also showed strong associated with the physical (mean = 58.0, SD = 10.6, p <  0.001), psychological (mean 68.2 SD = 14.81 p <  0.001) and environmental health domains (mean = 59.7, SD = 13.47, p <  0.001). Further regression analysis showed a strong association with physical health domain for HIV positive caregivers (p = 0.014) and adherent paediatric patients (p = 0.005). Nuclear family also showed a strong association with psychological (p <  0.001) and environmental (p = 0.001) health domains.

Conclusion
This study showed a strong association between the quality of life domains and the involvement of nuclear family caregiver, HIV-positive caregiver and adherence to HAART. Our study suggests that the involvement of any member of the nuclear family, HIV positive parents and patient adherence to therapy can improve the quality of life of paediatric HIV/AIDS patients on highly active antiretroviral therapy in the two hospitals.

Abstract
Background
Milk being a suitable medium for bacterial growth, it can serve as a source of bacterial contamination. Pathogenic bacteria in milk pose a serious health threat to humans and constitute about 90% of all dairy-related diseases. However, there are few studies that examined the health hazards of raw milk consumption in Ethiopia. Therefore, the objective of this study was to assess the prevalence of bacterial contamination and associated factors in milk produced for commercial purpose in Tigray region, northern Ethiopia.

Methods
This study used a cross-sectional study design, selected 315 persons (168 cafeterias, 96 dairy farms, and 51 milk vendors) for interview and collected the same number of bulk raw milk samples using systematic sampling procedure. Data were collected on socio-demographic, farm hygiene and milk handling practices by trained health professionals. Bacterial contamination was defined as total bacterial count (TBC) > 1 × 105, staphylococcus count (SC) > 105, or coliform count (CC) > 102 CFU/ml by culture and the species of bacteria were determined by standard biochemical tests.

Results
From the 315 milk samples tested, the prevalence of bacterial contamination was 52% (95% CI: 46.5–57.6). The mean counts of contaminated samples of TBC, SC, and CC were 8.94 ± 0.46 Standard Deviation (SD), 8.52 ± 0.6 SD, and 8.78 ± 0.49 SD log CFU/ml, respectively. The proportion of contamination was significantly lower in milk collected from dairy farms (32/96, 33.3, 95% CI: 24.5–43.2) compared to milk from vendors (33/51, 64.7, 95% CI: 51.4–66.2) and cafeterias (99/168, 58.9, 95% CI, 50.9–76.85). The milk samples were culture-positive for Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, K. oxytoca and Citrobacter freundii.

Conclusions
Over half of the sampled raw milk exhibited bacterial contamination with increasing trend from farmers to points of sale. Thus, milk vendors and cafeteria owners should apply good hygienic and sanitation practices during handling of milk; use appropriate, clean containers, and cold chain during milk transportation; and refrigeration of milk during storage.

Abstract
Background
Tuberculosis (TB) elimination requires treatment of millions of persons with latent M. tuberculosis infection (LTBI). LTBI treatment acceptance depends on population-wide TB knowledge and low stigma, but limited data are available on the relationship between stigma and knowledge. We assessed knowledge of TB disease and LTBI throughout Brazil and examined their association with TB stigma and incidence.

Methods
We performed a nationwide survey with multi-stage probability design through AmericasBarometer from April–May 2017; the sample was representative of Brazil at regional and national levels. Knowledge of and stigma toward TB were assessed by validated survey questions.

Results
Survey-weighted responses of 1532 individuals suggest that 57% of the population knew LTBI can occur, and 90% would seek treatment for it. Regarding active TB, 85% knew TB symptoms, 70% reported they should avoid contact with someone with active TB, and 24% had stigma toward persons with TB (i.e., thought persons with tuberculosis should feel ashamed, or deserved their illness). In regression models adjusting for clinical and demographic variables, knowledge of LTBI was associated with increased stigma toward persons with TB (adjusted odds ratio [OR] = 2.13, 95% confidence interval [CI]: 1·25–3.63, for “should feel ashamed”; OR = 1·82, 95% CI: 1·15–2·89, for “deserve illness”). Adjusting for regional TB incidence did not affect this association.

Conclusions
High proportions of this representative Brazilian population had knowledge of LTBI and were willing to seek treatment for it. However, such knowledge was associated with TB-specific stigma. Strategies to educate and implement treatment of latent tuberculosis must include efforts to decrease TB stigma.

Abstract
Background
Conservative treatment remains the preferred choice for distal radius fracture in children. However, loss of reduction is problematic, especially in an older child. Crossed Kirschner-wires is widely used to treat distal radius fracture in adolescents. This study aimed to compare the application of crossed Kirschner-wiring (KW) and non-bridging external fixator (EF) for the treatment of delayed distal radial fracture involving metaphyseal diaphyseal junction (MDJ) in adolescents.

Methods
Between January 2012 to January 2017, 146 (male = 101, female = 45) patients in EF group and 117 (male = 76, female = 41) in KW group, were reviewed retrospectively. Preoperative data were collected from the hospital database, and postoperative clinical outcomes data were collected during the follow-up visits. We used SPSS for data analysis.

Results
There existed no significant difference between EF and KW regarding sex, body weight, fracture side, duration from injury to surgery. The duration of surgery was significantly shorter in EF (30.5 ± 6.1 min) than the KW group (44.6 ± 9.4 min), P < 0.001. The number of intraoperative X-ray images was significantly lower in EF (6.5 ± 1.1) than KW (11.8 ± 2.3), P < 0.001. The incidence of tendon irritation is significantly higher in the KW (19.7%) than the EF group (0%), P < 0.001. The residual angulation on the AP view was higher in KW (3.8 ± 2.3, degrees) than the EF group (2.5 ± 1.6, degrees), P < 0.001. The volar tilting is better in EF (6.6 ± 1.1, degrees) than the KW group (1.0 ± 1.5, degrees), P < 0.001. However, the functional outcomes of the wrist showed no significant difference between EF and KW group, P = 0.086.

Conclusion
The EF was superior to KW in the treatment of radial MDJ fractures in adolescents. The EF displayed shorter duration of surgery, less tendon irritation, and better radiographic outcomes than the KW. However, the cost-effect analysis remains to be investigated, because the EF is more expensive than KW.

Published: June 2020

AbstractBackgroundThyroid hormone has been shown to be involved in carcinogenesis via its effects on cell proliferation pathways. The objective of this study is to determine the association between subclinical hypothyroidism (SCH) and the risk of incident cancer and cancer mortality via systematic review.MethodsA systematic search was performed on Medline and Pubmed to identify relevant studies. Randomized controlled trials, and observational studies assessing SCH or its treatment and the risk of incident cancer or cancer mortality were identified.ResultsA total of 7 cohort and 2 case-control studies met our inclusion criteria. In general, these studies were of medium to good quality. Overall, studies revealed no association between SCH and breast and prostate cancer. One study found that untreated SCH may be associated with an increased risk of colorectal cancer (adjusted odds ratio [OR]: 1.16; 95% confidence interval [CI]: 1.08–1.24). One study showed an increased risk in thyroid cancer incidence (adjusted OR: 3.38; 95% CI: 2.05–5.59) associated with elevation of a thyroid stimulating hormone (TSH) of > 1.64mIU/L. Two studies found an increase in cancer mortality among patients with SCH compared to euthyroid individuals; in contrast one study found no association between subclinical hypothyroidism and cancer mortality among aging men.ConclusionThe number of studies examining thyroid dysfunction and cancer risk and mortality is limited. Future studies assessing the association between thyroid dysfunction and cancer risk and mortality are needed, which will further address the need to treat subclinical hypothyroidism.
Association between periodontitis and all-cause and cancer mortality: retrospective elderly community cohort study
Authors: Chung Ping-Chen , Chan Ta-Chien 
Published: June 2020

AbstractBackgroundPeriodontal infection induces inflammation, which may increase the risk of tumor-promoting effects. The aim of this study was to assess the association between periodontitis and all-cause mortality, and all-cancer and specific cancers’ mortality in a health examination cohort of the elderly in the communities.MethodsA dataset of health examinations for the elderly with cause of death from 2005 to 2012 was obtained from the Department of Health, Taipei City Government. We enrolled 82,548 study participants with 262,035 visits. A Cox proportional hazards model and Cox frailty model were used for calculating the hazard ratios under different periodontal status by using SAS and Rstudio.ResultsBeing male, elderly, having a low education level, and smoking were risk factors for mortality in this retrospective elderly community cohort study. Participants with periodontitis followed across time had significantly higher hazard ratios (HRs) for all-cause mortality and all-cancer mortality (HR = 1.092, 95% confidence interval (CI):1.038 to 1.149, HR = 1.114, 95% CI:1.032 to 1.203, respectively) in the Cox frailty models after adjusting for age, marital status, education level, sex, and smoking status. After adjusting for age and sex, the hazard ratio was 1.185 (95% CI: 1.027 to 1.368) for lung cancer mortality, and 1.340 (95% CI: 1.019 to 1.762) for prostate cancer mortality in the periodontitis group with each visit.ConclusionsThe findings indicated that being male, having a low education level, and daily smoking were risk factors for mortality, and showed mixed evidence that periodontal disease is associated with all-cause, all-cancer and specific-cancer mortality including lung and prostate cancer. We suggest the importance of regular health screening in order to achieve early disease detection and lower mortality risk.

Published: June 2020

Abstract
Background
The present study aimed to characterize factors associated with patients issued DNR orders during hospitalization who are discharged alive without any instruction orders by physicians regarding end-of-life treatment, with a focus on the timing of DNR order issuance.

Methods
In total, 2997 DNR cases from all 61,037 patients aged ≥20 years admitted to a representative general hospital in Tokyo were extracted and divided into two groups by patient hospital release status (discharged alive/deceased). Study items included age, sex, disease type (non-cancer/cancer), hospital department (internal medicine/others), timing of DNR order issuance, implementation (or not) of life-sustaining treatment (LST) or the presence of any restrictions on LST and hospital length of stay. We conducted multiple logistic regression analysis, setting hospital release status as the dependent variable and each above study item as explanatory variables.

Results
DNR orders were issued at a rate of 4.9%. The analysis revealed that patients with a DNR who were ultimately discharged alive were statistically more likely to be those for whom DNR orders are issued early after admission (adjusted odds ratio: AOR, 13.7), non-cancer patients (AOR, 3.4), internal medicine department patients (AOR, 1.63), females (AOR, 1.34), and elderly (aged ≥85 years; AOR, 1.02); these patients were also less likely to be receiving LST (AOR, 0.36).

Conclusions
By focusing on those with DNR orders who were ultimately discharged alive, we discovered that these patients were likely to have DNR orders issued early after admission, and that they were more likely to be elderly, female, non-cancer patients, or those in internal medicine departments. Further examination of these data may help to elucidate why these particular DNR-related characteristics (including socio-economic and cultural factors) are evident in patients who end up being discharged alive.

Abstract
Background
Electronic medical records (EMRs) have been used for nearly three decades. Pharmacists use EMRs on a daily basis, but EMRs have only recently been incorporated into pharmacy education. Some pharmacy programs have implemented teaching electronic medical records (tEMRs), but best practices for incorporating tEMRs into pharmacy education remain unknown. The objectives of this study were to 1) assess pharmacy students’ views and experiences with a tEMR; and 2) identify current learning activities and future priorities for tEMR use in pharmacy education.

Methods
We used a mixed-methods approach, including three, two-hour student focus groups and a 42-item web-based survey to examine student perspectives of the tEMR. All first, second, and third year professional pharmacy students were eligible to participate in the survey and a focus group. Web-based survey items were measured on a 7-point Likert scale, and quantitative analyses included descriptive statistics. Two researchers independently coded transcripts using both deductive and inductive approaches to identify emergent themes. These analysts met and resolved any coding discrepancies via consensus.

Results
Focus groups were conducted with 22 total students, with 6–8 students represented from each year of pharmacy training. The survey was completed by 156 students: 47 first year, 55 second year, and 54 third year. Overall, 48.7% of survey respondents altogether agreed or strongly agreed that using the tEMR enhanced their learning in pharmacy classes and laboratories. Qualitative data were organized into four major themes regarding tEMR adoption: current priorities for use within the pharmacy curriculum; tEMR benefits; tEMR barriers; and future priorities for tEMR use to prepare students for pharmacy practice.

Conclusions
This study reveals pharmacy students’ perspectives and attitudes towards using a tEMR, the types of classroom activities that incorporate the tEMR, and students’ future suggestions to enhance the design or application of the tEMR for their learning. Our research findings may aid other pharmacy programs and promote more effective use of tEMRs in pharmacy education. In the long-term, this study may strengthen pharmacy education on EMRs and thus increase the efficacy and safety of pharmacists’ EMR use for patients’ medication management.

AbstractBackgroundIn the Kingdom of Saudi Arabia, the nursing profession faces significant challenges including; failure to recruit high school students into nursing education, poor nursing identity, and lack of awareness about the nursing profession. The level of community awareness and public image of the nursing profession are critical to recruit and retain students into nursing education, and to improve nurses’ sense of identity.AimTo explore the level of community awareness and public image of the nursing profession in Saudi Arabia.MethodsWe conducted a cross-sectional study with a convenient sample of 502 adults including106 males and 396 females, their mean age was 22.93 ± 6.76 years. Data collected included; socio-cultural data, gender preference in getting nursing care, awareness, and perceived socio-cultural barriers to pursue a nursing career. Data were analyzed using SPSS version 21.0.ResultsOnly 32.5% preferred to get nursing care by Saudis. The nursing profession was not viewed as a respected job as 71.5% of participants would be ashamed of having a nurse in their families. The study revealed a low median knowledge score (50.0, IQR: 50.0–66.7)). The study highlighted a number of socio-cultural barriers to pursue a nursing career including; the gender-mixed working environment (35.9%), delayed marriage of female nurses (20.3%), and the negative effect of nursing profession on social life (64.5%).ConclusionsHalf of the sample had a knowledge score below 50.0 out of 100. This level of poor awareness, in addition to socio-cultural perceived barriers are the main factors contributing to the negative public image of the nursing profession in Saudi Arabia. Understanding these factors could contribute to implementing focused intervention to improve the negative stereotype of the nursing profession among Saudis.
