ABSTRACT

PURPOSE: Highly active antiretroviral therapy (HAART) has brought a significant reduction in HIV/AIDS-related morbidity and mortality. However, metabolic abnormalities (eg, dyslipidemias) have continued to pose significant challenges, warranting a switch between antiretroviral agents and/or the introduction of a statin. Hence, the purposes of this study was to compare the efficacy of switching between antiretroviral agents versus introducing a statin in the long-term management of HAART-induced dyslipidemia in people living with HIV, and to identify the most potent agent in switching therapies.

METHODS: A comprehensive literature search of PubMed and Medline identified articles published from the years 2000 to 2020 in the English language, resulting in 84 articles, 30 of which were selected based on inclusion and exclusion criteria. Information on primary and secondary outcomes was extracted. Statistical analysis was done on the variables, and the differences between groups were considered significant at P < 0.05.

FINDINGS: Statin use was associated with significant reductions in triglycerides and total cholesterol (TC) at 6 weeks (both, P < 0.01). A switch of antiretroviral agents was associated with gradual reductions in TC and triglycerides for up to 48 weeks (both, P < 0.01). Statin use was associated with a reduced CD4 count at 24 weeks (P < 0.01). A switch of antiretroviral agents was associated with an increased CD4 count at 48 weeks (P < 0.01).

IMPLICATIONS: Statins were as effective as switching antiretroviral therapies in the short-term management of TC and triglycerides in patients with HAART-induced dyslipidemia.

ABSTRACT

OBJECTIVE: To explore the changes in microcirculation and microvasculature of the bulbar conjunctiva during the short-term wearing of the scleral lenses (ScCL). And investigate the factors affecting the microcirculation and microvasculature of the bulbar conjunctiva.

METHODS: In this prospective cross-sectional study, functional slit lamp biomicroscopy (FSLB) was used to image the ocular surface microcirculation and microvascular images at two different sites (under the area of ScCL and outside of the area of ScCL) before (baseline) and during the wearing of ScCL at 0 h, 1 h, 2 h and 3 h. Anterior segment optical coherence tomography (AS-OCT) (RTVue, Optovue Inc, USA) was also used to image central post-lens tear film (PoLTF) and the morphology changes of the conjunctiva under the landing zone at the same time period. The semi-automatic quantification of microcirculation and microvasculature including vessel density (D_box), vessel diameter (D), axial blood flow velocity (Va) and blood flow volume (Q). And the morphological changes of conjunctiva and PoLTF fogging grading were evaluated manually. The changes in the microcirculation and microvasculature of the ocular surface, PoLTF fogging grade and conjunctival morphology were compared before and during the ScCL wearing at different time periods, and the relationship between them was analyzed.

RESULTS: Nineteen eyes (11 right eyes, 8 left eyes) were analyzed in this study. Outside of the area of ScCL, the D_box before wearing lenses was less than that at 0 h (P = 0.041). The Q at baseline was greater than that after 1 h ScCL wearing (P = 0.026). Under the area of the ScCL, the Q at 1 h was less than that at baseline and 3 h. During the ScCL wearing, statistically significant conjunctival morphology changes were found among different time stages (baseline (0 μm), 0 h (113.18 μm), 2 h (138.97 μm), 3 h (143.83 μm) (all P ＜0.05). Outside the area of the ScCL, the morphology changes of the conjunctiva were negatively correlated with the changes of Va (P＜0.001,r = -0.471) and Q (P = 0.003,r = -0.348),but positively correlated with the D_box (P = 0.001,r = 0.386). Under the area of ScCL, the morphology changes of the conjunctiva were negatively correlated with the Q (P = 0.012, r = -0.291). The fogging grade was positively correlated with the Q under the area of the ScCL (P = 0.005, r = 0.331).

CONCLUSIONS: The microcirculation and microvasculature of the ocular surface and conjunctival morphology were changed after wearing ScCL in wearers, which indicated that the microvascular responses happened in the ScCL wearers and the severity of microvascular responses of the ocular surface related to the morphology changes of the conjunctiva. The quantification methods and findings in this study provide clues for the safety of ScCL wearing and may supervise the health of the wearer’s ocular surface.

ABSTRACT

OBJECTIVES: The aim of this superiority trial was to investigate the clinical outcomes of arthrocentesis as an early treatment supported by use of an occlusal splint vs use of an occlusal splint only in the management of temporomandibular joint (TMJ) arthralgia.

METHODS: Ninety-five adults presenting with TMJ arthralgia were recruited into the study and randomised into 2 groups: Group 1 received arthrocentesis as an early treatment supported by use of an occlusal splint, whereas group 2 received treatment with an occlusal splint only. Seventy-four patients (group 1: n = 37; group 2: n = 37) completed the 1-year follow-up schedule and were included in the final analysis. Reduction of pain intensity measured by a numeric rating scale and increase in mouth opening distance (unassisted maximal, assisted maximal, and pain-free) was seen in both treatment groups.

RESULTS: In group 1, pain intensity significantly decreased at 6 weeks and all subsequent time points compared with group 2. In terms of mouth opening distance, a significant improvement was observed in both groups during the course of treatment, but statistical significance was not seen between the 2 treatment groups.

CONCLUSIONS: Early arthrocentesis supported by use of an occlusal splint is superior to use of an occlusal splint alone in the treatment of TMJ arthralgia. Arthrocentesis with occlusal splint support could be discussed as first-line treatment for arthralgia of the TMJ, which may co-occur with various painful and nonpainful conditions of TMJ disorders.

ABSTRACT

BACKGROUND: Health care spending by households can be a great indicator of a society’s commitment to good health stewardship and the efficiency of institutions responsible for managing health costs. Equitable and appropriate distribution of dental services is a challenging issue for realising universal health coverage. This study aimed to evaluate Iranian households’ per capita dental expenditure (DE) according to their socioeconomic status (SES).

METHODS: In this cross-sectional study, the income and expenditure of 18,701 urban and 19,261 rural households in Iran were scrutinised according to the data provided by the Statistics Center of Iran (2017-2018). After model creation, the SES index was determined using principal component analysis and weighting based on the analytical hierarchy process. The dependent variable was the share of per capita household’s expenditure spent on dental health. The zero-inflated gamma regression model was applied to confirm the presumed association between per capita DE and SES. Analyses were performed using PROC NLMIXED in SAS software (version 4.9).

RESULTS: The results revealed that approximately 9% of urban and 4% of rural households paid for dental treatments in the past month. The DE to total health expenditure (HE) ratios were 8.5% and 14.8% for rural and urban households, respectively. Also, with each level increase in SES, the average per capita DE increased by 23% and 16% in rural and urban households, respectively.

CONCLUSIONS: The study confirms association between per capita DE and SES in Iran. This implies targeted strategies to facilitate the utilisation of dental care especially for lower SES groups according to their needs.

ABSTRACT

INTRODUCTION AND AIMS: Violations of the mandibular canal (MC) and mental foramen (MF) and subsequent injuries to their neurovascular bundle have been reported after surgical and nonsurgical dental procedures. Besides using advanced technologies such as cone-beam computed tomography (CBCT), clinicians should be aware of the anatomy and location of MC and MF in different populations. This study aims to describe the morphologic characteristics of the MF, MC, and its intrabony location in relation to the apices of mandibular posterior teeth in an Emirati subpopulation using CBCT.

METHODS: A total of 3700 CBCT scans were screened, and 154 scans that met the inclusion and exclusion criteria were randomly selected. The scans were assessed using 3-dimensional multiplanar imaging for the following structures: the location of MF and the MC course, its intrabony location, and its relationship to the apices of the mandibular posterior teeth. The data were analysed statistically using SPSS software.

RESULTS: The MC ran lingually and inferiorly at the posterior region and became more buccal and superior towards the MF. The distal root of the mandibular second molar was found to be the closest root to the MC (2.06 ± 1.83 mm). Moreover, the most common location of the MF was distal to the contact area between the 2 premolars (0.83 ± 1.84 mm) with a significant negative correlation to age (with and increase in age, the MF moves distally). The distance between the root apices and the MC was statistically significantly affected by age (positive correlation) and gender (male patients had a greater distance).

CONCLUSIONS: The common course of the MC is lingual and inferior posteriorly and becomes more buccal and superior towards the MF, which is located mostly between the mandibular first and second premolars. Furthermore, the distal root of the mandibular second molar is the closest to the MC and has a positive relationship with age.

ABSTRACT

BACKGROUND: A personalized approach to assessing medication knowledge may identify opportunities for education to support self-management of cystic fibrosis (CF). This project describes the development, scoring, and preliminary validity of the Personalized CF Medication Questionnaire (PCF-MQ), designed to assess knowledge of prescribed CF medication purpose, administration, and dose and frequency.

METHODS: Participants completed the PCF-MQ, the Knowledge of Disease Management (KDM-CF), and the Cystic Fibrosis-Medication Beliefs Questionnaire (CF-MBQ). Prescribed regimens were abstracted from medical records. Eligibility criteria were age 12 years and older, diagnosed with CF, and prescribed a CF medication. Statistical analyses were conducted using R software. Spearman rho was used to test correlations between measures.

RESULTS: Sixty people with CF (pwCF) were enrolled; three people reported a regimen that substantially deviated from the medical record and were excluded from the analyses. The mean (SD) age was 20.2 (7.3) years, 54 % were female, and 74 % had a FEV1pp ≥70 %. The mean (SD) PCF-MQ total score was 77.8 (12.3) and knowledge scores ranged from a low of 58.3 for levalbuterol to 100 for ivacaftor. The PCF-MQ total score correlated with the KDM total score and subscales (Spearman Rho= 0.32-0.59, p < 0.05) and was not correlated with the CF-MBQ subscales (p > 0.05)).

CONCLUSIONS: The PCF-MQ was correlated with another measure of general CF knowledge, but not health beliefs; because of the small sample size, this should be considered preliminary evidence of its validity. Advantages over existing CF knowledge measures include its practicality for use to help assess pwCF’s knowledge about their prescribed regimen.

ABSTRACT

BACKGROUND/PURPOSE: The incidence of inflammatory bowel disease (IBD) rapidly increases in Asia, and western dietary pattern is suspected to be the major risk factor. Despite this, there has been a lack of studies analyzing the relationship between dietary patterns and IBD in Taiwan. This study examines the dietary habits of Taiwanese individuals with and without IBD to inform clinical dietary recommendations for IBD patients.

METHODS: We collected baseline characteristics and dietary habits from both IBD patients and healthy controls from February and August 2022 in Chang Gung memorial hospital using a structured and validated food frequency questionnaire. The dietary habits of IBD patients in this study were focused on the six months leading up to their IBD diagnosis.

RESULTS: Our study recruited 98 IBD patients and 184 healthy controls. In demographic characteristics, cigarette smoking is more common in IBD group. Besides, distinct dietary patterns were observed between groups. The healthy controls demonstrated a higher consumption of whole foods and antioxidants. By contrast, the IBD group consumed more western-style foods but the difference didn’t reach statistical significance.

CONCLUSION: Our study found that healthy controls in Taiwan embraced a dietary pattern rich in whole foods that may prevent IBD or reduce IBD disease activity. Nonetheless, a larger sample size is needed to further provide valuable dietary guidance for general population in Taiwan for IBD prevention or for patients with IBD for disease activity control.

ABSTRACT

OBJECTIVE: Depression is an important public health issue among older adults, often associated with their sleep-related problems. We aimed to investigate the association between sleep-related problems and depressive symptoms among Chinese community-dwelling older adults.

METHODS: This cross-sectional study utilized self-reported data from 2896 participants (aged ≥60 years) from Shanghai, China. Nocturnal sleep duration and difficulty initiating sleep (DIS) symptoms were obtained through face-to-face questionnaires. Nocturnal sleep duration was categorized as ‘short’ (<7 h), ‘normal’ (7-8 h), and ‘long’ (>8 h). Subsequently, the 3 groups were further divided into 6 groups based on the presence of DIS, and the combined sleep behaviors were termed ‘sleep patterns’. Logistic regression was conducted to assess the association of sleep variables and sleep patterns with the risk of depressive symptoms.

RESULTS: Compared to the reference group, ‘short sleep duration’ and DIS symptoms were associated with depressive symptoms (with odds ratios (OR) of 1.50 and 1.79, respectively, with 95% confidence intervals (CI) of 1.14-1.97 and 1.39-2.31). When compared to ‘normal sleep duration without DIS’, both ‘short sleep duration with DIS’ (OR = 2.60, 95% CI: 1.81-3.72) and ‘normal sleep duration with DIS’ (OR = 1.60, 95% CI: 1.03-2.49) were statistically associated with depressive symptoms in adjusted regression models.

CONCLUSION: Short sleep duration and DIS symptoms were found to be associated with depressive symptoms. Combining DIS symptoms with sleep duration, DIS was identified as a risk factor for elevated depressive symptoms in individuals with short and normal sleep durations. In managing depressive symptoms, it is imperative to thoroughly evaluate insomnia and nighttime sleep, which can provide valuable insights for nursing and medical policy.

ABSTRACT

INTRODUCTION: Pharmacogenetics evaluates how genetic variations influence drug responses. Nowadays, genetic tests have advanced, becoming more affordable, and its integration is supported by stronger clinical evidence. Guidelines such as those from CPIC (Clinical Pharmacogenetics Implementation Consortium) and resources like PharmGKB facilitate genotype-based prescribing; and organizations like the FDA promote genetic testing before initiating certain medications. Preventive pharmacogenetic panels seem promising, but further research on biomarkers and diverse populations is needed. The aim of this review is to analyze recent evidence on the genotype-drug response relationship to examine how the genetic profile of patients influences the clinical response to treatments, and analyze the areas of research that need further study to advance towards a genetic-based precision medicine.

MATERIALS AND METHODS: A systematic search was conducted on PubMed to identify articles investigating the genotype-drug response relationship. The search strategy included terms such as “pharmacogenetics”, “personalized treatment”, “precision medicine”, “dose adjustment”, “individualized dosing”, “clinical routine” and “clinical practice.” Clinical trials, observational studies, and meta-analyses published in English or Spanish between 2013 and 2023 were included. The initial search resulted in a total of 136 articles for analysis.

RESULTS: 49 articles were included for the final analysis following review by two investigators. A relationship between genetic polymorphisms and drug response or toxicity was found for drugs such as opioids, GLP-1 agonists, tacrolimus, oral anticoagulants, antineoplastics, atypical antipsychotics, efavirenz, clopidogrel, lamotrigine, anti-TNF-α agents, voriconazole, antidepressants, or statins. However, for drugs like metformin, quetiapine, irinotecan, bisoprolol, and anti-VEGF agents, no statistically significant association between genotype and response was found.

CONCLUSION: The studies analyzed in this review suggest a strong correlation between genetic variability and individual drug responses, supporting the use of pharmacogenetics for treatment optimization. However, for certain drugs like metformin or quetiapine, the influence of genotype on their response remains unclear. More studies with larger sample sizes, greater ethnic diversity, and consideration of non-genetic factors are needed. The lack of standardization in analysis methods and accessibility to genetic testing are significant challenges in this field. As a conclusion, pharmacogenetics shows immense potential in personalized medicine, but further research is required.

ABSTRACT

OBJECTIVE: Early recognition of the need for surgical intervention is crucial in terms of limiting amputation level and decreasing mortality. We aimed to determine the risk factors for limb loss in patients with diabetic foot infection (DFI).

METHOD: Data of hospitalised patients with a DFI between 2010 and 2019 were collected retrospectively from their hospital records. Clinical and laboratory findings were analysed according to the type of treatment.

RESULTS: Data were collected for 401 patients, 280 (69.8%) of whom were male. The mean age was 59.6±11.1 years. Treatment modalities included: medical treatment (36.4%); debridement/drainage (21.9%); minor amputation (17.7%); and major amputation (23.9%). Forefoot infection (odds ratio (OR): 3.347; 95% confidence interval (Cl): 1.408-7.956) and peripheral arterial disease (OR: 4.990; 95% Cl: 1.225-20.324) were found to be significant in predicting limb loss, while duration of diabetes (≥20 years) and absence of forefoot infection were significant predictors of debridement/drainage. Subgroup analysis showed that high leukocyte levels (>16.4K/μl) and forefoot infections were independent predictors for major and minor amputation, respectively.

CONCLUSION: The clinical parameters used in this study are simple, broadly available, cost-effective and promising for predicting limb loss in patients with DFI.
