Characteristics of older adults living with HIV accessing home and community care services in British Columbia,Canada

ABSTRACT

Over half of people living with HIV (PLHIV) engaged in care in British Columbia (BC) are age ≥50. The public home and community care (HCC) system offers formal support that PLHIV may turn to as they age, but little is known about access specific to PLHIV. Using data from the STOP HIV/AIDS cohort, which includes linked treatment and demographic records for PLHIV accessing care in BC, we compared older PLHIV (defined as those age ≥50) who did and did not access HCC services. We estimated adjusted odds ratios (aORs) for factors associated with HCC service utilization using logistic regression. This study included 5,603 PLHIV age ≥50, 837 (14.94%) of whom accessed any HCC service between 2005 and 2015. Services most commonly used were community nursing (8.98%, n?=?503) and rehabilitation (7.73%, n?=?433). Those who received HCC were more likely to be female (aOR?=?1.56, 95% CI?=?1.24, 1.98), have a history of injection drug use (aOR?=?1.88, 95% CI?=?1.57, 2.25), have a higher Charlson comorbidity score (aOR?=?1.11, 95% CI:1.07, 1.15) and to have visited a general practitioner in the past year (aOR?=?2.17, 95% CI?=?1.77, 2.67). Approximately 15% of older PLHIV have accessed HCC, but the extent of potential unmet need for these services requires further research.     

I125 irradiation stent for treatment of hepatocellular carcinoma with portal vein thrombosis: A meta-analysis

PurposeA meta-analysis aimed to systematically evaluate the safety and efficiency of I¹²⁵ irradiation stent placement for patients with hepatocellular carcinoma (HCC) combined with portal vein tumor thrombosis (PVTT).Materials and methodsThe Cochrane library, PubMed/Medline, EMBASE, CNKI, Wanfang Data and CQVIP were systematically screened out from the earliest to December 2019. The qualities of all included studies were assessed. The primary endpoints were the 6-month, 12-month stent cumulative patency rate and 6-month, 12-month, 24-month overall survival rate while the secondary endpoints were the objective response rate of PVTT, main portal venous pressure changes and treatment-related adverse events. Our meta-analysis was conducted using Stata 12.0 software.ResultsTotally seven studies with 1018 patients were included in the final analysis, in which 602 patients received TACE and I¹²⁵ irradiation stent placement, and 416 patients in control group underwent TACE and stent placement without endovascular brachytherapy (EVBT). Meta-analysis showed that the I¹²⁵ irradiation stent improved the cumulative stent patency rates in 6 months [OR = 1.65, 95% CI (1.32–2.05), P < 0.001] and 12 months [OR = 2.55, 95% CI (1.90–3.42), P < 0.001] and the survival rates in 6 months [OR = 1.77, 95% CI (1.41–2.22), P < 0.001], 12 months [OR = 3.14, 95% CI (2.24–4.40), P < 0.001] and 24 months [OR = 7.39, 95% CI (3.55–15.41), P < 0.001]. However, there was no difference in the objective response rate of PVTT [OR = 1.13, 95% CI (0.87–1.48), P = 0.365], main portal venous pressure and the occurrence adverse event [OR = 0.88, CI = 0.72–1.08, P = 0.212] between two groups.ConclusionI¹²⁵ irradiation stent seems to be more effective in treating hepatocellular carcinoma with portal vein tumor thrombosis. The usage of portal vein stent combined endovascular brachytherapy has the potential to act as an alternative therapy for HCC with PVTT. On account of the limitation of studies included, more studies with high-level evidence, such as RCTs, are requisite to support the above promising results.

Identification of key genes and pathways in discoid lupus skin via bioinformatics analysis

Discoid lupus erythematosus (DLE) is the most common skin manifestation of lupus; however, the molecular mechanisms underlying DLE remain unknown. Therefore, we aimed to identify key differentially expressed genes (DEGs) in discoid lupus skin and investigate their potential pathways.To identify candidate genes involved in the occurrence and development of the disease, we downloaded the microarray datasets {"type":"entrez-geo","attrs":{"text":"GSE52471","term_id":"52471"}}GSE52471 and {"type":"entrez-geo","attrs":{"text":"GSE72535","term_id":"72535"}}GSE72535 from the Gene Expression Database (GEO). DEGs between discoid lupus skin and normal controls were selected using the GEO2R tool and Venn diagram software (http://bioinformatics.psb.ugent.be/webtools/Venn/). The Database for Annotation, Visualization, and Integrated Discovery (DAVID), Enrichr, and Cytoscape ClueGo were used to analyze the Kyoto Encyclopedia of Gene and Genome pathways and gene ontology. Protein-protein interactions (PPIs) of these DEGs were further assessed using the Search Tool for the Retrieval Interacting Genes version 10.0.Seventy three DEGs were co-expressed in both datasets. DEGs were predominantly upregulated in receptor signaling pathways of the immune response. In the PPI network, 69 upregulated genes were selected. Furthermore, 4 genes (CXCL10, ISG15, IFIH1, and IRF7) were found to be significantly upregulated in the RIG-I-like receptor signaling pathway, from analysis of Enrichr and Cytoscape ClueGo.The results of this study may provide new insights into the potential molecular mechanisms of DLE. However, further experimentation is required to confirm these findings.     

The effectiveness of specialized nursing interventions for patients with Parkinson disease: A randomized controlled study protocol

Background:The purpose of this experiment is to evaluate the impact of the care of Parkinson disease nurse specialist on improving motor symptoms and life quality for patients with Parkinson disease (PD).Method:This is a randomized controlled research, and it will be conducted from April 2021 to October 2021 at Sichuan Provincial People''s Hospital. The experiment was granted through the Research Ethics Committee of Sichuan Provincial People''s Hospital (004510293). All the patients suffer from PD, age 18 years or older, both female and male, regardless of the duration or severity of this disease are eligible. The exclusion criteria contains: lack sufficient knowledge to complete questionnaires, serious physical comorbidities or refuse to take part in the program. In our experiment, the major result measures are motor symptoms and life quality. For the measurement of life quality, we will utilize Parkinson disease Questionnaire-39, the most extensively utilized the scale of life quality in PD. The evaluation of motor symptoms severity is carried out with the revision of Unified Parkinson Disease Rating Scale sponsored by Movement Disorder Society.Results:Table 1 indicates clinical outcomes at different time points.Conclusion:The Parkinson''s disease nurse specialist care may promote the life quality in the PD patients.Trial registration number:researchregistry 6284.     

Pediatric Wilson disease presenting as acute liver failure: Prognostic indices

BACKGROUNDAcute liver failure (ALF) can be a primary presentation of Wilson disease (WD). Mortality rates are high in WD with ALF (WDALF). Predictions of mortality in WDALF vary by model and are sometimes contradictory, perhaps because few patients are studied or WD diagnoses are questionable. AIMTo determine the outcomes among well-documented WDALF patients and assess mortality model performance in this cohort.METHODSWe reviewed the medical records of our pediatric WDALF patients (n = 41 over 6-years-old, single-center retrospective study) and compared seven prognostic models (King’s College Hospital Criteria, model for end-stage liver disease/pediatric end-stage liver disease scoring systems, Liver Injury Unit [LIU] using prothrombin time [PT] or international normalized ratio [INR], admission LIU using PT or INR, and Devarbhavi model) with one another.RESULTSAmong the 41 Han Chinese patients with ALF, WD was established by demonstrating ATP7B variants in 36. In 5 others, Kayser-Fleischer rings and Coombs-negative hemolytic anemia permitted diagnosis. Three died during hospitalization and three underwent liver transplantation (LT) within 1 mo of presentation and survived (7.3% each); 35 (85.4%) survived without LT when given enteral D-penicillamine and zinc-salt therapy with or without urgent plasmapheresis. Parameters significantly correlated with mortality included encephalopathy, coagulopathy, and gamma-glutamyl transpeptidase activity, bilirubin, ammonia, and serum sodium levels. Area under the receiver operating curves varied among seven prognostic models from 0.981 to 0.748 with positive predictive values from 0.214 to 0.429.CONCLUSIONWDALF children can survive and recover without LT when given D-penicillamine and Zn with or without plasmapheresis, even after enlisting for LT.
