(1) Background: COVID-19 continues to represent a worrying pandemic. Despite the high percentage of non-severe illness, a wide clinical variability is often reported in real-world practice. Accurate predictors of disease aggressiveness, however, are still lacking. The purpose of our study was to evaluate the impact of quantitative analysis of lung computed tomography (CT) on non-intensive care unit (ICU) COVID-19 patients’ prognostication; (2) Methods: Our historical prospective study included fifty-five COVID-19 patients consecutively submitted to unenhanced lung CT. Primary outcomes were recorded during hospitalization, including composite ICU admission for the need of mechanical ventilation and/or death occurrence. CT examinations were retrospectively evaluated to automatically calculate differently aerated lung tissues (i.e., overinflated, well-aerated, poorly aerated, and non-aerated tissue). Scores based on the percentage of lung weight and volume were also calculated; (3) Results: Patients who reported disease progression showed lower total lung volume. Inflammatory indices correlated with indices of respiratory failure and high-density areas. Moreover, non-aerated and poorly aerated lung tissue resulted significantly higher in patients with disease progression. Notably, non-aerated lung tissue was independently associated with disease progression (HR: 1.02; p-value: 0.046). When different predictive models including clinical, laboratoristic, and CT findings were analyzed, the best predictive validity was reached by the model that included non-aerated tissue (C-index: 0.97; p-value: 0.0001); (4) Conclusions: Quantitative lung CT offers wide advantages in COVID-19 disease stratification. Non-aerated lung tissue is more likely to occur with severe inflammation status, turning out to be a strong predictor for disease aggressiveness; therefore, it should be included in the predictive model of COVID-19 patients.

Abstract Background The burden of severe malaria is uncertain at the population level because existing estimates rely heavily on data from the formal healthcare system. Using data from population-based surveys, this analysis examines severe malaria cases at the population level, which captures malaria positive children whose caregivers 1) have taken the child to a healthcare facility but the child’s illness did not resolve, or 2) have not sought care for the child’s illness. Direct inclusion of these children in severe malaria estimates has been an underlying data gap. Methods This analysis examined data from 37 Demographic and Health Surveys and Malaria Indicator Surveys across 19 countries in sub-Saharan Africa collected between 2011 and 2018. The outcome of interest is a proxy indicator for severe malaria, defined as children age 6-59 months who were positive for malaria with at least one self-reported symptom of severe illness including loss of consciousness, rapid breathing, seizures, or severe anemia (hemoglobin <5 g/dl). The study includes a weighted descriptive, country-level analysis and a multilevel mixed-effects logistic regression model to assess the determinants of severe malaria. Results Among children positive for malaria across all surveys, 4.5% (95% CI 4.1–4.8) had at least one sign or symptom of severe malaria, which was significantly associated with age, residence, wealth, and fieldwork year at a p-value less than 0.05. Malaria positive children in the higher malaria transmission zone were more likely to have signs or symptoms of severe malaria compared to those in the lowest transmission zone; however, these results were not statistically significant. Conclusion Having an accurate estimate of severe malaria cases among malaria positive children is essential to assessing the impact of malaria interventions and to guiding future malaria investments. This analysis presents a novel approach of estimating severe malaria cases among malaria positive children under age five in malaria endemic countries. Estimating severe malaria cases through household-based surveys allows countries to estimate severe malaria across time and to compare with other countries. Having a population level estimate of severe malaria cases helps further our understanding of the burden and epidemiology of severe malaria.

10087 Background: Evidence for a strong link between skeletal muscle depletion and poor outcomes in mCRC is growing. However, the impact of SMI changes over time on progression and OS during palliative systemic Tx is not known. The CAIRO3 study (Simkens et al. Lancet 2015) randomized 556 mCRC patients after 6 cycles capecitabine+oxaliplatin+bevacizumab (CAPOX-B) to maintenance CAP-B Tx (Main) vs. observation (Obs). Upon 1st disease progression (PD1), CAPOX-B or other treatment was reintroduced until 2nddisease progression (PD2). This is the first analysis using scan data of multiple time-points to investigate SMI changes during palliative systemic treatment Tx and its association with survival. Methods: 1227 CT-scans of a random selection of 416 CAIRO3 patients (mean age 64±9 years, Main n = 206; Obs n = 210) were analyzed for SMI (skeletal muscle area at the L3 level in cm2/m2). Using mixed model analysis, SMI changes were analyzed for two intervals; interval 1: from randomization to PD1, and interval 2: from PD1 to PD2. Three Cox regression models were used to study the association between SMI loss and time to PD2 and death for interval 1, and time to death for interval 2. Main and Obs groups were combined in the analyses since the p-value for interaction was not significant. Hazard ratios (HR) were reported per 2 units change in SMI. Results: Median times from randomization to PD1, PD2 and death were 7.7, 13.5 and 24 months resp. During interval 1 (less intensive or no Tx) patients gained SMI on average (1.2 units; 95%CI 0.6-1.8), but 23% of patients still lost SMI. SMI loss was associated with shorter time to PD2 (HR 0.88; 0.81-0.98, p= .01), but not with shorter OS (HR 0.94; 0.86-1.02, p= .17). During interval 2 (more intensive Tx) average SMI loss was -2.2 units ( 1.5-2.8) and 63% of patients lost SMI. SMI loss was associated with shorter OS (HR 0.73; 0.62-0.86, p< .00). Conclusions: Loss of SMI was related to shorter time to progression during first line less intensive main Tx or obs and shorter overall survival during more intensive reinduction Tx. This large longitudinal study suggests that SMI preservation may be a therapeutic goal. Clinical trial information: NCT00442637.

Abstract The inhibitor of DNA binding protein 4 (ID4) is a member of dominant negative basic helix loop helix (bHLH) transcription factor family that has a HLH domain but lacking DNA-binding domain. Methylation of ID4 in B-cell lineage malignancies including CLL and germinal center non-Hodgkin lymphomas (GC-NHLs) has been described. To date, the impact of Id4 loss in CLL has not been demonstrated. We utilized the TCL1 transgenic mouse model of human CLL to study the importance of loss of ID4 in disease progression. We demonstrated that ID4 was silenced by methylation only at the time mice had symptomatic leukemia. We therefore sought to investigate if earlier loss of Id4 would accelerate CLL progression. We generated mice with haploid loss of Id4 in TCL1 transgenic background by breeding homozygous TCL1 transgenic mice and mice with heterozygous Id4 mutant gene. By comparing to the control littermates with heterozygous TCL1 oncogene, mice with the loss of Id4 occur to have significantly accelerated CLL disease progression with shorter overall survival (12 versus 16 months, p-value&lt;0.0001). The pathological analysis on Id4 mutant mice demonstrated that the CLL symptoms such as the elevated white blood cell counts, enlarged spleen and lymphoid tissues. We then performed the microarray studies on 1 month old TCL1 mice with control or mutant Id4 to identify ID4-dependent transcriptional changes in primary B-cells. Among the identified targets, genes involved in cell proliferation and anti-apoptosis were then verified. Supportively, B-cells from Id4 mutant TCL1 mice have significantly (p-value&lt;0.001) diminished apoptosis in response to dexamethasone treatment. Additionally, both significant in vitro (p-value&lt;0.001) and in vivo (p-value=0.025) increased proliferation of Id4 mutant TCL1 B-cells after the stimulation by CpG685NO168 was demonstrated. These data provide support that Id4 acts as tumor suppressor in transformed B-lymphocytes and is silenced through the process of methylation. The Effort to identify binding partners of Id4 in CLL cells and targeting its re-expression is warranted.

AbstractIntroduction. Diabetic neuropathy (DN) is one of the most devastating complications of diabetes mellitus; however, in contrast to other countries, there are no scientific studies in Portugal evaluating the impact of demographic and clinical characteristics of this pathological entity. The aim of this study was to evaluate the impact of gender, metabolic control, age of diabetic patients, as well as time of disease progression, the appearance of complaints related to neuropathic pain.Material and methods. A multicentre study with a non-probabilistic, convenience sample of 359 patients was performed employing the quantitative method, using the Statistical Package for Social Science 24 software. The p-value of p < 0.05 was defined to consider a result statistically significant. The Spearman correlation coefficient (r) was determined to determine the relationship between categorical variables.Results. There was no statistically significant difference in the prevalence of DN between genders (p = 0.633 and r = 0.025). There was a statistically significant relationship between the value of HbA1c and DN, with p = 0.010 and r = 0.136. There is a relationship between age and complaints of neuropathic pain, with p = 0.034 and r = 0.112. The variable, time of disease progression, is also correlated with the appearance of complaints of neuropathic pain with p = 0.020 and r = 0.112.Conclusion. The prevalence of neuropathic pain in subjects with diabetes is not negligible and is associated with modifiable risk factors that can be identified, possibly modified and prevented. The correct approach for these patients, which involves screening and early treatment, is decisive improving functionality and quality of life.

Objective: While the use of intraoperative laser angiography (SPY) is increasing in mastectomy patients, its impact in the operating room to change the type of reconstruction performed has not been well described. The purpose of this study is to investigate whether SPY angiography influences post-mastectomy reconstruction decisions and outcomes. Methods and materials: A retrospective analysis of mastectomy patients with reconstruction at a single institution was performed from 2015-2017.All patients underwent intraoperative SPY after mastectomy but prior to reconstruction. SPY results were defined as ‘good’, ‘questionable’, ‘bad’, or ‘had skin excised’. Complications within 60 days of surgery were compared between those whose SPY results did not change the type of reconstruction done versus those who did. Preoperative and intraoperative variables were entered into multivariable logistic regression models if significant at the univariate level. A p-value <0.05 was considered significant. Results: 267 mastectomies were identified, 42 underwent a change in the type of planned reconstruction due to intraoperative SPY results. Of the 42 breasts that underwent a change in reconstruction, 6 had a ‘good’ SPY result, 10 ‘questionable’, 25 ‘bad’, and 2 ‘had areas excised’ (p<0.01). After multivariable analysis, predictors of skin necrosis included patients with ‘questionable’ SPY results (p<0.01, OR: 8.1, 95%CI: 2.06 – 32.2) and smokers (p<0.01, OR:5.7, 95%CI: 1.5 – 21.2). Predictors of any complication included a change in reconstruction (p<0.05, OR:4.5, 95%CI: 1.4-14.9) and ‘questionable’ SPY result (p<0.01, OR: 4.4, 95%CI: 1.6-14.9). Conclusion: SPY angiography results strongly influence intraoperative surgical decisions regarding the type of reconstruction performed. Patients most at risk for flap necrosis and complication post-mastectomy are those with questionable SPY results.

BACKGROUND INTRODUCTION: The Kenyan constitution seeks to guarantee every citizen the right to quality healthcare services. Quite often this delivery is hampered by geographical location, socio-economic statuses among other factors. The country has a high mobile phone penetration rate. Digitalization of the healthcare sector is a vital aspect that contributes to effective delivery of care services. This study set out to assess the impact of mobile technology in closing the gaps within the health care service delivery. The objective of the study was to investigate the impact of mobile phone technology in bridging the gap in healthcare service delivery in Kenya with a focus on Nairobi, Kibera informal settlements. Hypothesis testing using P-value of 0.05 also showed that use of mobile phone technology positively impacted the delivery of healthcare services. OBJECTIVE The objective of the study was to investigate the impact of mobile phone technology in bridging the gap in healthcare service delivery in Kenya with a focus on Nairobi, Kibera informal settlements. Hypothesis testing using P-value of 0.05 also showed that use of mobile phone technology positively impacted the delivery of healthcare services. METHODS The target population were patients visiting Médecins Sans Frontières (MSF) clinic in Kibera informal settlements. A cross-sectional study design was employed. Purposive and simple random sampling method was used to select the study sample of 210 participants and 3 healthcare providers. Data were collected using survey questionnaire that was provider-administered and Data were analyzed using SPSS version. RESULTS The characteristics of the respondents were general (mean age, education level, social economic status) to only patients who visited the clinics for HIV tests and other related services such as going for ARVs. The main findings showed that 66.12% of the respondents (14.29% strongly agreed + 55.24% agreed) that the use of mobile phone technology improved their access to healthcare services. Using chi square, there was a statistical difference due to the positive impact of mobile technology on healthcare delivery (p=0.05). CONCLUSIONS The study findings showed that 66.12% of the respondents agreed that the use of mobile phone technology and SMS improved their access to healthcare services. The results hypothesis also proved that use of mobile phone technology positively impacts the delivery of healthcare services.

Greater pricing presume on audit service has been put by the regulations of the auditing and accounting practices for the disclosure of audit fees, since audit fee is directly related to audit quality. However, the audit fees perceived by the client is often different from the amount charged by the auditors. Hence, this study investigated the impact of firm-specific characteristics on audit fees of quoted consumer goods firms in Nigeria using a purposive sampling technique. Secondary data were obtained from annual reports of the companies for the period from 2009-2016. The empirical result from Breusch-Pagan Lagrange Multiplier Test (BP-LM) produced a chi-square value of 13.94 with p-value of 0.0001 indicating that pooled ordinary least squares (OLS) will not be appropriate for the study. The Hausman test showed a chi-square of 23.55 with a p-value of 0.001 indicating that the null hypothesis is strongly rejected. Thus, the only estimate from the fixed effect model was interpreted to explain the relationship between firm-specific characteristics and audit fees of quoted consumer goods firms in Nigeria. The result revealed that auditee size, auditee risk, auditee profitability and IFRS adoption are the firm specific characteristics that impact on audit fees with only auditee size and IFRS adoption being positively related to audit fees while the other factors are negatively related to audit fees. Based on this finding, this study concluded that the firm’s specific factors are the major drivers of audit fees in Nigeria consumer goods firms. This study recommends among others that companies should implement corporate governance principles that address issues relating to board independence and committee sizes to guide activities in the consumer goods sector since profitability behave negatively with audit fees.

BACKGROUND: HIV/AIDS-Associated Lipodystrophy Syndrome includes changes in body fat distribution, with or without metabolic changes. The loss of fat from the face, called facial lipoatrophy, is one of the most stigmatizing signs of the syndrome.OBJECTIVES:To evaluate the effect of FL treatment using polymethylmethacrylate (PMMA) implants on disease progression, assessed by viral load and CD4 cell count.METHODS: This was a prospective study of 44 patients treated from July 2009 to December 2010. Male and female patients, aged over 18 years, with clinically detectable FL and who had never been treated were included in the study. PMMA implantation was done to fill atrophic areas. Laboratory tests were conducted to measure viral load and CD4 count before and after treatment.RESULTS: Of the 44 patients, 72.72% were male and 27.27% female, mean age of 44.38 years. Before treatment, 82% of patients had undetectable viral load, which increased to 88.6% after treatment, but without statistical significance (p = 0.67). CD4 count before treatment ranged from 209 to 1293, averaging 493.97. After treatment, the average increased to 548.61. The increase in CD4 count after treatment was statistically significant with p = 0.02.CONCLUSION: The treatment of FL with PMMA implants showed a statistically significant increase in CD4 count after treatment, revealing the impact of FL treatment on disease progression. Viral load before and after treatment did not vary significantly.

The long period of tuberculosis treatment causes patients to have a high risk of forgetting or stopping the medication altogether, which increases the risk of oral anti-tuberculosis drug resistance. The patient’s knowledge and perception of the disease affect the patient’s adherence to treatment. This research objective was to determine the impact of educational videos in the local language on the level of knowledge, perception, and adherence of tuberculosis patients in the Regional General Hospital (RSUD) Bangil. This quasi-experimental study design with a one-month follow-up allocated 62 respondents in the intervention group and 60 in the control group. The pre- and post-experiment levels of knowledge and perception were measured with a validated set of questions. Adherence was measured by pill counts. The results showed that the intervention increases the level of knowledge of the intervention group higher than that of the control group (p-value < 0.05) and remained high after one month of follow-up. The perceptions domains that changed after education using Javanese (Ngoko) language videos with the Community Based Interactive Approach (CBIA) method were the timeline, personal control, illness coherence, and emotional representations (p-value < 0.05). More than 95% of respondents in the intervention group take 95% of their pill compared to 58% of respondents in the control group (p-value < 0.05). Utilization of the local languages for design a community-based interactive approach to educate and communicate is important and effective.
