METHODS: This cross-sectional study was conducted in two tertiary centres. A forward and backward translation was conducted for the QOD. The translated questionnaire was distributed to subjects with self-reported smell disorders on days 1 and 7. Internal consistency was analysed using Cronbach's alpha and test-retest reliability was tested with an intraclass correlation coefficient. Confirmatory factor analysis was performed to test construct validity.
RESULTS: A total of 375 participants were recruited, 52 dropped out and 323 completed the questionnaire a second time. The Cronbach's alpha coefficient was 0.537 for parosmia (P), 0.892 for life quality (LQ), 0.637 for sincerity (S) and 0.865 for visual analogue score (VAS). The intraclass correlation coefficient (ICC) for domain scores was > 0.9, while the ICC for all items was good to excellent. A three-factor model for mQOD showed an acceptable fit with indices chi-square value (CMIN)/degree of freedom (DF) = 3.332, Tucker-Lewis fit index (TLI) = 0.923, comparative fit index (CFI) = 0.939, root mean square error of approximation (RMSEA) = 0.079 and standardised root mean square residual (SRMR) = 0.0574.
CONCLUSION: The mQOD is a valid and reliable tool for assessing OD in patients.
METHODS: A total of 93 patients with American Society of Anaesthesiologists (ASA) physical status I or II having lower limb orthopaedic surgery under spinal anaesthesia were randomised into two groups that received either Volulyte (n = 47) or Gelaspan (n = 46). Before the spinal anaesthesia, these patients were pre-loaded with 500 mL of the fluid of their respective group. Blood samples were taken before pre-loading and again after spinal anaesthesia and sent for venous blood gas and electrolyte level measurement. Baseline and intraoperative records of systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR) and the requirement of ephedrine to treat hypotension were also recorded.
RESULTS: Both fluids could not prevent significant reductions in SBP (P = 0.011), DBP (P = 0.002) and MAP (P = 0.001). There was also significant reduction in HR over time (P < 0.001). There was no significant difference in terms of ephedrine usage between both groups. Neither Volulyte 6% nor Gelaspan 4% caused significant changes in acid-base status.
CONCLUSION: The use of 500 mL of either Gelaspan 4% or Volulyte 6% as pre-loading fluids did not significantly prevent the incidence of post-spinal anaesthesia hypotension following orthopaedic lower limb surgery; however, both were useful in the maintenance normal acid-base balance.
Methods: The instrument is a 41-item Likert scale form parental questionnaire designed to screen ASD among children aged 6 years old-12 years old. It was filled out by the parents of 700 children (children with ASD = 47; typically developing children = 653) who were contacted through five special education schools and seven mainstream primary schools.
Results: Findings showed that Malay AQ-Child has an internal consistency of 0.82 as a whole scale for 41-items. Receiver operator characteristic analysis showed that the cut score of 63 for the translated, reduced version of the AQ-Child with 41 items had 99% area (95% confidence interval [CI]) under receiver operating characteristic (ROC) curve, and sensitivity and specificity of 93% and 99%, respectively. As for factor structure, principal component analysis (PCA) showed good loading values for most of the items in the instrument.
Conclusion: The translated version of the Malay AQ-Child for screening ASD can further facilitate the process of surveillance and early intervention for children who need it.
METHODS: PubMed, the Excerpta Medica dataBASE (EMBASE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Google Advanced Search, and Turning Research Into Practice (TRIP) Database were systematically searched from inception to August 2023. The primary outcomes were knowledge level, knowledge scores, participation in shared decision-making (SDM), decisional conflict, and preference for SDM participation. Secondary outcomes were the proportion of subjects who underwent screening (actual screening utilisation) and the proportion of subjects who intended to be screened (intention to undergo screening). Network and pairwise meta-analyses were performed using random-effects models.
RESULTS: Seven systematic reviews were included. Network meta-analysis found that multimedia (relative risk [RR] 1.51, 95% confidence interval [CI] 1.02-2.24), print (RR 1.82, 95% CI 1.23-2.69), and website-based (RR 1.99, 95% CI 1.32-3.01) DAs significantly increased participation in SDM compared to the computer-based DA. There was a significant reduction in the actual screening utilisation in the computer DA arm compared to the other delivery modes. No significant differences between all delivery modes were noted on knowledge levels, knowledge scores, decisional conflict, preference for SDM participation, and intention to undergo screening. The highest mean surface under the cumulative ranking curve for all primary outcomes showed that website-based was the most effective delivery mode, followed by print-based DA. The pairwise meta-analysis showed a significant increase in participants' knowledge level, knowledge scores, a reduced intention to undergo screening and actual screening utilisation compared to UC.
CONCLUSIONS: The findings suggest that different types of DAs have varying levels of effectiveness in increasing knowledge level, knowledge scores, participation in SDM, and influencing screening behaviours. While website-based DA appeared the most effective, employing the print-based DA could be a practical solution in settings with limited resources.
METHODS: A comprehensive systematic literature search was conducted from January 2000 to February 2023 across Web of Science, Google Scholar, and MEDLINE via PubMed. The review sought studies on technology-based exercise prescriptions for adults ≥ 18 years, evaluating features that enhance motivation or adherence.
RESULTS: Out of 1724 articles reviewed, 45 met the criteria, demonstrating that mobile applications, exercise gaming, wearable trackers, and websites are commonly used technologies for prescribing exercise in healthcare setting. Common features, special features, and motivating features were found to be important in all technology-based exercise tools to enhance users' adherence and motivation.
CONCLUSION: This review provides a comprehensive overview of the technological types and approaches that can support and improve exercise adherence among health service users. The findings also emphasize on specific features that can address current gaps in technology-driven fitness interventions.
PRACTICE IMPLICATIONS: Healthcare professionals should make informed decisions when recommending these tools to health service users, since technology does play a significant role in promoting long-term adherence to exercise programs.
MATERIALS AND METHODS: A total of 140 patients who had compatible ABO blood type with negative T-cell lymphocytotoxicity crossmatch were included in the study and 25% of them were spousal transplant donors. No remarkable differences in acute rejection rate, graft survival, patient survival and serum creatinine level were observed between the spousal and living-related donor groups.
RESULTS: The spousal donor group had a higher degree of HLA mismatch than the living-related donor group. HLA-A mismatch was associated with increased rejection risk at 6 months (odds ratio [OR], 2.75; P = 0.04), 1 year (OR, 2.54; P = 0.03) and 3 years (OR, 3.69; P = 0.001). It was also observed in the deleterious effects of HLA-B and HLA-DQ loci when the number of antigen mismatches increased. The risk was 7 times higher in patients with ≥1 mismatch at HLA-A, HLA-B and HLA-DR loci than those who did not have a mismatch at these loci at 6 months (P = 0.01), 1 year (P = 0.03) and 3 years (P = 0.003).
CONCLUSION: A good match for HLA-A, HLA-B, HLA-DR and HLA-DQ can prevent acute rejection risk in renal transplant patients. Consequently, spousal donor transplants could be a safe intervention in renal patients.
METHODS AND STUDY DESIGN: An observational study was conducted on 63 post-bariatric surgery patients who had undergone bariatric surgery between two weeks and five years after surgery. The participants were assessed for the complications experienced, current comorbidities, anthropometric changes, dietary intake, and psychological well-being. A three-day, 24-hour diet recall was done to assess the dietary intake of the patients. The mean macronutrient and micronutrient intakes were compared to several available recommendations. The DASS-21 questionnaire was administered to determine the psychological well-being of the participants.
RESULTS: The most common complications experienced by patients after bariatric surgery were hair loss (50.8%), gastroesophageal reflux disease (GERD) (49.2%), and vomiting (41.3%). There were significant differences in mean weight before (129.5 (33.0) kg/m2) and after (85.0 (32.0) kg/m2) bariatric surgery (p<0.001). The prevalence of clinically severe obesity declined by 55%. Overall, patients had insufficient intake of some nutrients such as protein, fat, calcium, and iron. Majority of the patients experienced a normal level of stress, anxiety, and depression, but some had mild (3.2%), moderate (4.8%), and severe anxiety (1.6%).
CONCLUSIONS: There were drastic improvements in patients' weight following bariatric surgery. However, there were several complications including nutrient deficiencies. Due to the anatomical changes in the gastrointestinal tract, patients must comply with the dietary and lifestyle changes and follow up with the healthcare professional. A nutrition module will be helpful for patients to prepare for and adapt to the changes after bariatric surgery.
OBJECTIVES: To establish the average peak and trough concentrations of apixaban and rivaroxaban from real-world studies.
METHODS: PubMed, Scopus, and Web of Science were searched until October 2023 for observational studies reporting apixaban and rivaroxaban concentrations. Meta-regression was used to examine factors influencing these concentrations.
RESULTS: Sixteen studies involving 1054 apixaban and 1321 rivaroxaban patients were pooled using random-effects model. Mean apixaban peak concentrations were 157 ng/mL (95% CI, 127-187) for 2.5 mg and 228 ng/mL (95% CI, 204-252) for 5 mg, with trough concentrations of 77 ng/mL (95% CI, 56-98) and 113 ng/mL (95% CI, 101-124), respectively. Mean rivaroxaban peak concentrations were 168 ng/mL (95% CI, 104-232) for 10 mg, 225 ng/mL (95% CI, 192-257) for 15 mg, and 229 ng/mL (95% CI, 193-264) for 20 mg, with trough concentrations of 23 ng/mL (95% CI, 13-32), 31 ng/mL (95% CI, 26-36), and 36 ng/mL (95% CI, 25-47), respectively. Meta-regression revealed age and creatinine clearance correlated with apixaban peak concentrations. Creatinine clearance correlated with apixaban and rivaroxaban trough concentrations.
CONCLUSION: The pooled mean concentrations align with expected concentration ranges reported in different pharmacokinetic studies.
CLINICAL PICTURE: This is a report of a case of metastatic adenocarcinoma of colorectal origin to the paranasal sinuses in a 52-year-old female who was previously treated for adenocarcinoma of the sigmoid colon. A histologic study of the surgical specimen from the sinonasal cavity demonstrated a tumour identical to the patient's prior primary tumour of the colon. The sinonasal neoplastic tissue showed marked positivity for carcinoembryonic antigen and expressed cytokeratin 20, which differentiates metastatic colonic adenocarcinoma from ITAC.
TREATMENT/OUTCOME: The patient received palliative radiation but died 3 months after the diagnosis.
CONCLUSION: Distinguishing metastatic adenocarcinoma from gastrointestinal tract from ITAC can be difficult. In view of the resemblance, immunohistochemical staining can help in differentiating them. It is important to recognise these as metastatic lesions as the treatment is mainly palliative.
OBJECTIVE: In this study, the researchers conducted a scoping literature review of the web-based dietary changes and physical activity-related intervention programs designed for the patients with hypertension and identified the methodologies, effectiveness, protocols, and theories, which could affect and improve existing clinical activities.
METHODS: This review followed the scoping review methodology to identify and process the peer-reviewed studies published between 2010 and 2020. The literature searches were conducted on the following electronic databases: PubMed, Web of Science, MEDLINE (Medical Literature Analysis and Retrieval System Online), ScienceDirect, Scopus, and Google Scholar. By using relevant search terms, studies were included if they offered information related to the web-based intervention tools, specifically dietary and physical activity intervention for patients with hypertension. Studies written or translated in English language and published within the date range (January 2010 to March 2020) were included.
RESULTS: Overall, 1441 articles were initially identified. The reviewers included 35 articles after removing duplicates and screening titles. Only 21 articles were assessed for full review, and 15 were kept for analysis. The researchers selected 15 web-based intervention articles published on the topic of hypertension from 7 countries. A few of these 15 web-based tools (4, 27%) included more than 3 functions and provided a lot of important information (such as appointments, health records, or viewable care). Several tools were standalone tools (11, 73%), while most of the tools supported communication intervention-related lifestyle or behavioral changes (13, 87%) and medication adherence (6, 40%). It was found that physicians (9, 60%), allied health professionals (5, 33%), and nurses (5, 33%) were the health care providers who generally used these tools for communicating with their patients. More than half of the above tools (10, 67%) were assessed by different researchers in randomized controlled trials, while 5 tools (33%) were investigated in nonrandomized studies.
CONCLUSIONS: We identified many web-based intervention programs for patients with hypertension from the literature databases. The findings indicate that numerous benefits can be derived after using a web-based dietary and physical activity intervention program for hypertension focusing on lifestyle changes. However, developers need to consider the preferences of the patients with regard to the information or the design features while developing or modifying web-based educational websites. These tools could be used for designing a patient-tailored website intervention program that is based on diet and physical activities for patients with hypertension.
METHODS AND RESULTS: This study utilized different enrichment activities which catered for food, sensory, and cognitive enrichment. Eleven fresh fecal samples from captive Malayan tigers at Zoo Melaka and Night Safari were collected under different conditions. All samples were extracted and 16S rRNA V3-V4 region amplicon sequencing was used to characterize the gut microbiome of captive Malayan tigers subjected to various enrichment activities. Firmicutes, Actinobacteriota, and Fusobacteriota were the dominant phyla observed in the gut microbiome of captive Malayan tigers during enrichment activities. This study revealed β-diversity significantly varied between normal and enrichment phase, however no significant differences were observed in α-diversity. This study demonstrates that environmental enrichment improves the gut microbiome of Malayan tigers because gut microbes such as Lachnoclostridium, which has anti-inflammatory effects and helps maintain homeostasis, and Romboutsia, which has a probiotic effect on the gut microbiome.
CONCLUSIONS: This study provides valuable insights into the effects of enrichment activities on the gut microbiome of captive Malayan tigers, offering guidance for enhancing captive management practices aimed at promoting the health and well-being of Malayan tiger in captivity.
METHODS: This was a cross-sectional observational study on patients with Type II diabetes mellitus from October 2020 to May 2021. Data collected include systolic/diastolic blood pressure, visual acuity, glycated hemoglobin, and central macular thickness. Diabetic retinopathy severity was categorized using the Early Treatment Diabetic Retinopathy Study classification. Photoplethysmography signals were acquired using pulse-oximeter modules (OEM-60; Dolphin Medical, Inc) measured for 90 seconds at 275 Hz sampling rate and 16-bit resolution, which records photoplethysmography fitness index, vascular risk prediction index, and vascular age.
RESULTS: One hundred and forty-one patients were equally distributed into six DR categories. Mean age was 58.8 ± 9.9 years, with female-to-male ratio of 1.27. There were significant differences in mean systolic (125.5 ± 10.0 mmHg, P = 0.007) and diastolic blood pressure (80.0 ± 8.8 mmHg), mean glycated hemoglobin (7.6 ± 1.9%, P = 0.005), median log unit of minimal angle of resolution (0.3, interquartile range: 0.2-0.5, P < 0.001), and central macular thickness ( P = 0.003) across DR severity. Significant differences were also seen in photoplethysmography fitness index ( P = 0.001), vascular risk prediction index ( P < 0.001), and vascular age ( P = 0.001), with poorer values in severe compared with mild/moderate DR. After adjusting for age, blood pressure, and glycated hemoglobin, photoplethysmography fitness reduces by 3.3% (regression coefficient, b = -3.27, P < 0.001), vascular age increases by 2.5 years ( b = 2.54, P = 0.002), and vascular risk prediction index increases by 3.1 ( b = 3.08, P < 0.001) with every DR worsening.
CONCLUSION: More severe DR stages were associated with poorer photoplethysmography vascular markers.
