METHOD: Potential miRNAs associated with NAFLD in HCC tumorigenesis were identified through a systematic review, and their roles were evaluated by data mining analysis. The biological function of the potential miRNA and its target genes in NAFLD and HCC were evaluated by bioinformatic analysis.
RESULT: MIR122 was identified as the potential miRNA associated with NAFLD and HCC. Then, MIR122 expression was significantly lower in HCC patients, and higher MIR122 levels were associated with significantly better overall survival. Next, the biological functions of MIR122 and target genes were predicted to be involved in inflammation, fibrosis, cell proliferation, invasion, metastasis, and apoptosis. In particular, the FOXO signaling pathway may regulate the above biological functions.
CONCLUSION: MIR122 was suggested to be involved in progressing from NAFLD to HCC through the PI3K/AKT/FOXO pathway.
SYSTEMATIC REVIEW REGISTRATION: PROSPERO, identifier: CRD 42024517940.
METHODS: Data were derived from Kuwait Catheterization Laboratory Project (Kuwait CLAP) registry. Adult patients (≥18 years) diagnosed with STEMI were enrolled in Kuwait CLAP registry between February 2020 and February 2021. Patients were categorized into insured and noninsured. The coprimary outcomes were the in-hospital and 30-day mortality in insured versus noninsured patients with STEMI. In-hospital and 30-day adverse cardiac outcomes were also compared.
RESULTS: Of 668 patients with STEMI, 116 (17%) were insured and 552 (83%) were not insured. Three (2.6%) of the insured and 9 (1.6%) of the noninsured patients suffered in-hospital mortality, while no patients in the insured group and four patients (0.7%) patients in the noninsured group suffered 30-day mortality, with no significant difference between the two groups (P = 0.447 and P = 1, respectively). The rates of in-hospital complications and 30-day adverse events were similar between the two groups.
CONCLUSIONS: Our findings suggest no differences in acute or short-term outcomes among patients with different insurance status in Kuwait. These findings are reassuring knowing that the free essential services provided by Kuwait government for STEMI patients did not compromise the outcomes of noninsured compared to insured patients.
METHOD: A retrospective record review study using positive COVID-19 cases and contact-tracing data from an area in Malaysia was performed and analysed using the SNA method through R software and visualised by Gephi software. The justification for utilizing SNA is its capability to pinpoint the individuals with the highest impact and accountability for the transmission of COVID-19 within the area, as determined through SNA.
RESULT: Analysis revealed 76 (4.5%) people tested positive for COVID-19 from 1,683 people, with 51 (67.1%) of the positive ones being male. Outdegrees for 38 positive people were between 1 and 12, while 41 people had 1-13 indegree. Older males have a higher outdegree, while younger females have a higher outdegree than other age groups among same-sex groups. Betweenness was between 0.09 and 34.5 for 15 people. We identified 15 people as super-spreaders from the 42 communities detected.
CONCLUSION: Women play a major role in bridging COVID-19 transmission, while older men may transmit COVID-19 through direct connections. Thus, health education on face mask usage and hand hygiene is important for both groups. Working women should be given priority for the work-from-home policy compared to others. A large gathering should not be allowed to operate, or if needed, with strict adherence to specific standard operating procedures, as it contributes to the spread of COVID-19 in the district. The SNA allows the identification of key personnel within the network. Therefore, SNA can help healthcare authorities recognise evolving clusters and identify potential super-spreaders; hence, precise and timely action can be taken to prevent further spread of the disease.
METHODS: The optimal concentration of MEPB to activate NK cells was determined using healthy blood samples, assessing the expression of IL-12, IL-18, IL-10, IL-8, IFN-γ, perforin, and granzyme B via an enzyme-linked immunosorbent assay (ELISA). NK cell purity from healthy donors and breast cancer patients was determined using specific antibodies, and the number of NK cells was assessed using flow cytometry and a hemocytometer. A co-culture experiment, ELISA, and apoptosis assay were used to evaluate NK-mediated cytotoxicity pathways.
RESULTS: ELISA data indicated that MEPB at 7.5 µg/ml significantly increased the expression of IFN-γ, IL-12, IL-18, perforin, and granzyme B while decreasing IL-8 and IL-10 expression after 20 hrs of incubation. The average NK cell purity was 87.09 ± 0.043%. Breast cancer patients exhibited lower NK cell counts than healthy donors. Co-culture experiments demonstrated that NK cells induced apoptosis in MDA-MB-231 breast cancer cells in the presence of MEPB by increasing perforin, granzyme B, and IFN-γ expression in both healthy donors and breast cancer patients-experimental groups. P. bleo enhances NK cell activation, promoting the apoptosis of triple-negative human breast cancer cells (MDA-MB-231), suggesting the potential use of MEPB leaves as an anti-cancer immunostimulant.
METHODS: Cell viability was tested on human periodontal ligament fibroblasts (HPLFs) using 3.125 mg/ml, 6.25, 12.5, 25, 50, 100 and 200 mg/ml, on both types of GICs employing MTT assay. For the Comet assay, HPLFs were treated with IC50, IC25 and IC10 of test materials and the tail moments were measured. In the Ames test, four genotypic variants of strains of Salmonella typhimurium (TA100, TA98, TA1537 and TA1535) and a strain of Escherichia coli (WP2 uvrA) were employed. The material tested was extracted using sterile distilled water (0.2 g per ml) at 37 °C for 72 h. This was considered as 100 %, which was diluted to 50, 25, 12.5 and 6.25 % utilizing sterile distilled water. These five concentrations were incubated with the bacterial strains with and without metabolic activation (S9), along with appropriate positive controls. The number of revertant colonies was used to evaluate the outcome.
RESULTS: The highest cell viability (159.4 %) for nano-HA-SiO2-GIC was noticed at 3.125 mg/ml, while the lowest (24.26 %) was observed at 200 mg per ml. IC50, IC25 and IC10 values were 95.27, 51.4 and 20.1 mg/ml for cGIC, 106.9, 55.8 and 22.9 mg/ml for nano-HA-SiO2-GIC, respectively. The IC10 of both test materials showed no significant DNA damage compared to that of the negative control based on the Comet assay. The plate treated with nano-HA-SiO2-GIC showed less than double the average number of revertant colonies compared to that of negative control with regard to the Ames test.
CONCLUSIONS: It can be concluded that nano-HA-SiO2-GIC is non-mutagenic based on the Ames test and did not cause DNA damage at the lowest concentration of IC10 based on the Comet assay.
METHOD: We describe the modification of a Foley catheter by trimming off the proximal urine drainage port, and using this opening to pass a metal stylet within the catheter, providing additional rigidity and allowing easier manipulation of the catheter tip. The catheter tip is then positioned in the superior limb of the T-tube, and the balloon inflated under direct visualization to occlude the opening and allow positive pressure ventilation through the external limb of the T-tube.
CONCLUSION: This simple yet effective technique can be considered in patients with T-tubes.
METHODS: Study 1: An Australian sample of participants with a diagnosed chronic physical health condition and a self-reported good physician-patient relationship completed a three round Delphi poll to determine items of the chronic condition physician-patient relationship scale (CC-PPR). Fifty-two participants completed round one, 33 completed round two, and 24 completed all three rounds. Study 2: Exploratory and confirmatory factor analysis were conducted on a separate sample (N = 226) to explore the factor structure of the CC-PPR.
RESULTS: The CC-PPR comprised 22 items within a single-factor structure which demonstrated high internal consistency (Cronbach's α = 0.97) and sound convergent validity.
DISCUSSION: The CC-PPR reliably measures observable, concrete, and specific physician behaviours that patients with chronic physical health conditions believe are critical in forming a good physician-patient relationship. The CC-PPR has potential application in research, educational, and self-assessment contexts, including for the evaluation and development of competence in post-graduate and professional settings.
