METHODS: A retrospective study in a single center, all adult patients who were diagnosed with primary hyperaldosteronism and underwent AVS in our center between 2014 until 2022 were included. Successful samples defined by a selectivity index of ≥2, that is, the ratio of adrenal vein cortisol level to the peripheral vein cortisol level, were evaluated. The baseline demographic characteristics of each patient, technical parameters of AVS, and anatomical parameters of right adrenal vein from the venographic images were evaluated and analyzed to correlate with the outcome of AVS. A P-value of <0.05 was considered statistically significant.
RESULTS: The overall success rate of AVS in our center was 61.3%. The success rate significantly increased to 80.6% in the trained interventional radiologist (IR) group, which represents a single IR who had completed specific training in AVS, compared to non-trained IR group which consisted of a total of 10 IRs without specific AVS training (P = 0.046). The right AVS had lower success rate than the left AVS (64% vs. 94.6%). The type of right adrenal vein pattern showed significant association with the outcome of AVS (P = 0.014). There were 6 types of right adrenal vein patterns observed in our study; Type 1 - gland-like pattern with numerous branches, Type 2 - delta pattern, Type 3 - triangular pattern with central "blush", Type 4 - no discernible pattern and Type 5 - spidery or stellate pattern. The sixth pattern was the hepatic radicles blush with hepatic drainage, for which blood sampling were also collected due to its appearance was frequently indistinguishable from the Type 1 pattern. The results showed Type 2 pattern had the highest incidence (30.5%; 32/105 samples) and Type 5 had the highest success rate (100%; 11/11 samples), while the hepatic radicles blush pattern had the highest incidence in fail samples resulting in the highest failure rate (94.7%; 18/19 samples). The visualization of the inferior emissary vein (IEV) from the venographic images during right AVS had a significant association with the successful AVS (97.5% success rate; 39/40 samples; P = 0.003). Contrariwise, blood sampling withdrawn from the right adrenal vein in the presence of hepatic drainage communication associated with the failure AVS (86.7% failure rate; 26/30 samples; P = 0.001).
CONCLUSIONS: The overall success rate of both AVS in our center was 61.3%, and the success rate was higher in the trained IR group than the non-trained IR group. The visualization of IEV and the type of right adrenal vein patterns were the key determining factors with significant association to the successful right AVS. Conversely, blood sampling withdrawn from the hepatic radicles and hepatic drainage had significant association with the failure right AVS.
METHODS: An indirect enzyme-linked immunosorbent assay (ELISA) was developed to evaluate the usefulness of USM.TOXO1 antigen for the detection of IgG antibodies against Toxoplasma gondii in human sera. Whereas the reactivity of the developed antigen against IgM antibody was evaluated by western blot and Dot enzyme immunoassay (dot-EIA) analysis.
RESULTS: The diagnostic performance of the new antigens in IgG ELISA was achieved at the maximum values of 85.43% and 81.25% for diagnostic sensitivity and specificity respectively. The USM.TOXO1 was also proven to be reactive with anti- T. gondii IgM antibody.
CONCLUSIONS: This finding makes the USM.TOXO1 antigen an attractive candidate for improving the toxoplasmosis serodiagnosis and demonstrates that multiepitope antigens could be a potential and promising diagnostic marker for the development of high sensitive and accurate assays.
CASE PRESENTATION: A 22-year-old African gentleman presented with left nasal obstruction and epistaxis for 2 years and was diagnosed with nasopharyngeal carcinoma. He subsequently underwent embolization of the maxillary branch of the left ECA using Embozene® Microspheres - 250 μm in size before endoscopic tumour excision to reduce intra-operative bleeding. He complained of sudden painless profound visual loss in the left eye (LE) two hours after embolization. Visual acuity in LE was no light perception. Fundus examination showed pale retina with no cherry red spot. Arterial narrowing and segmentation were seen in all quadrants. A diagnosis of left ophthalmic artery occlusion was made. Despite immediate management including ocular massage and lowering of intraocular pressure, the visual loss remained. Retrospective review of digital subtraction angiogram showed an anastomosis between the left ophthalmic artery and anterior deep temporal artery as a potential route for microspheres migration.
CONCLUSION: Pre-operative angio-architecture understanding and diligent selection of embolic material are helpful in preventing this adverse event. The use of newer agents for embolotherapy may cause migration of embolic material from the external to the internal carotid system leading to ophthalmic artery occlusion and blindness.
METHODS: This observational study was conducted between December 2018 and October 2019 at 25 PHCs in three regions in Malaysia. Each PHC was linked to one or more hospitals, for referral of seropositive participants for confirmatory testing and pretreatment evaluation. Treatment was provided in PHCs for non-cirrhotic patients and at hospitals for cirrhotic patients.
RESULTS: During the study period, a total of 15 366 adults were screened at the 25 PHCs, using RDTs for HCV antibodies. Of the 2020 (13.2%) HCV antibody-positive participants, 1481/2020 (73.3%) had a confirmatory viral load test, 1241/1481 (83.8%) were HCV RNA-positive, 991/1241 (79.9%) completed pretreatment assessment, 632/991 (63.8%) initiated treatment, 518/632 (82.0%) completed treatment, 352/518 (68.0%) were eligible for a sustained virological response (SVR) cure assessment, 209/352 (59.4%) had an SVR cure assessment, and SVR was achieved in 202/209 (96.7%) patients. A significantly higher proportion of patients referred to PHCs initiated treatment compared with those who had treatment initiated at hospitals (71.0% vs 48.8%, p<0.001).
CONCLUSIONS: This study demonstrated the effectiveness and feasibility of a simplified decentralised HCV testing and treatment model in primary healthcare settings, targeting high-risk groups in Malaysia. There were good outcomes across most steps of the cascade of care when treatment was provided at PHCs compared with hospitals.
OBJECTIVE: This review aimed to identify self-care approaches, domains, and their effectiveness for a proper self-care educational guide package for women with GDM.
DESIGN: A systematic review using electronic literature databases published between January 2016 and December 2022 was conducted.
DATA SOURCES: Web of Science, Scopus, and Ovid databases were used.
REVIEW METHODS: This review utilized the PICO (Population, Intervention, Comparison, and Outcomes) framework to screen the retrieved articles for eligibility in which mothers with GDM, educational materials, standard practice or intervention, and effectiveness were considered the PICO, respectively. The CIPP (Context, Input, Process, Product) model served as a framework for adopting the education development model. Mixed methods appraisal tool was used for quality assessment. Data extraction and synthesis without meta-analysis were presented as evidence tables.
RESULTS: A total of 19 articles on GDM were included in the final analysis (16 Intervention studies, two qualitative studies, and one mixed-methods study). Four broad domains emerged from the analysis: 1) information or knowledge of GDM, 2) monitoring of blood glucose levels, 3) practice of healthy lifestyles, and 4) other non-specific activities. The majority of the articles employed a face-to-face approach in executing the educational group sessions, and most studies disclosed their positive effects on GDM management. Other methods of evaluating intervention effectiveness were described as improved self-care behavior, increased satisfaction score, enhanced self-efficacy, good glucose control, and better pregnancy outcome.
CONCLUSION: Knowledge or information about GDM, healthy diet, and exercise or physical activity was found to be the most applied domains of intervention. Framework domains based on the present review can be used in the future development of any interventional program for GDM women in enhancing health information reaching the targeted group in promoting self-efficacy.
PROSPERO REGISTRATION NUMBER: CRD42021229610.
METHODS: PubMed and Scopus databases were searched based on PRISMA guideline to determine studies focusing on changes following NPC RT.
RESULTS: Eleven studies fulfilled the inclusion criteria. Microstructural changes occur most consistently in the temporal region. The changes were correlated with latency in seven studies; fractional anisotropy (FA) and gray matter (GM) volume remained low even after a longer period following RT and areas beyond irradiation site with reduced FA and GM measures. For dosage, only one study showed correlation, thus requiring further investigations.
CONCLUSION: DTI, DKI and VBM may be used as a surveillance tool in detecting brain microstructural changes of NPC patients which correlates to latency and brain areas following RT.
