ABSTRACT

PURPOSE: To evaluate the effectiveness of combined Tranexamic acid (TXA) and dexamethasone (DEX) in total hip and knee arthroplasty.

METHODS: PUBMED, EMBASE, MEDLINE and CENTRAL database were systematically searched for randomized studies that utilized TXA and DEX administration of TXA in THA or TKA.

RESULTS: A total of three randomized studies enrolling 288 patients were eligible for qualitative and quantitative analysis. DEX + TXA group demonstrated statistical significantly lesser usage of oxycodone (OR: 0.34, p < 0.0001), metoclopramide (OR: 0.21, p < 0.00001), lesser incidence of postoperative nausea and vomiting (OR: 0.27, p < 0.0001), better postoperative range of motion (MD: 2.30, p < 0.00001) and shorter length of hospital stay (MD: 0.31, p = 0.03). Comparable results were seen in total blood loss, transfusion rate and postoperative complications.

CONCLUSION: In this meta-analysis, the combination of TXA and DEX has positive impacts on the usage of oxycodone and metoclopramide, postoperative range of motion, postoperative nausea and vomiting and reduces the length of hospital stay.

ABSTRACT

PURPOSE: Older age, risks from pre-existing health conditions and socio-economic disadvantage are negatively related to the prospects of an early-stage cancer diagnosis. With older Aboriginal Australians having an elevated prevalence of these underlying factors, this study examines the potential for the mitigating effects of more frequent contact with general practitioners (GPs) in ensuring local-stage at diagnosis.

METHODS: We compared the odds of local vs. more advanced stage at diagnosis of solid tumours according to GP contact, using linked registry and administrative data. Results were compared between Aboriginal (n = 4,084) and non-Aboriginal (n = 249,037) people aged 50 + years in New South Wales with a first diagnosis of cancer in 2003-2016.

RESULTS: Younger age, male sex, having less area-based socio-economic disadvantage, and fewer comorbid conditions in the 12 months before diagnosis (0-2 vs. 3 +), were associated with local-stage in fully-adjusted structural models. The odds of local-stage with more frequent GP contact (14 + contacts per annum) also differed by Aboriginal status, with a higher adjusted odds ratio (aOR) of local-stage for frequent GP contact among Aboriginal people (aOR = 1.29; 95% CI 1.11-1.49) but not among non-Aboriginal people (aOR = 0.97; 95% CI 0.95-0.99).

CONCLUSION: Older Aboriginal Australians diagnosed with cancer experience more comorbid conditions and more socioeconomic disadvantage than other Australians, which are negatively related to diagnosis at a local-cancer stage. More frequent GP contact may act to partly offset this among the Aboriginal population of NSW.

ABSTRACT

PURPOSE OF REVIEW: Depression is prevalent and common among individuals living with diabetes. The aim of this review is to systematically assess and meta-analyze the treatment effect of cognitive-behavioral therapy for depression (and other affective outcomes) among patients with diabetes.

RECENT FINDINGS: Earlier investigations found both psychosocial and pharmacological interventions, including cognitive-behavioral therapy, were promising in managing depression in patients with diabetes, though these findings remain inclusive due to poor study designs and a small number of trials included, which calls for a comprehensive systematic review and meta-analysis. A total of 33 studies (89 effect sizes) reported a moderate and statistically significant treatment effect of cognitive-behavioral therapy for depressive symptoms among individuals with diabetes (d = 0.301, 95% CI 0.115-0.487, p < 0.001). On average, cognitive-behavioral therapy was effective for psychological stress/distress outcomes but not for anxiety or physiological outcomes. The findings of the study confirmed CBT as an effective treatment option for depression among diabetes patients and identified important areas for future research.

ABSTRACT

PURPOSE: To identify psychoeducational interventions that target parents of children with congenital abnormalities (CA) and evaluate their impact on quality of life (QoL).

METHODS: The search was conducted in six electronic databases, complemented by references of the studies found, studies of evidence synthesis, a manual search of relevant scientific meetings’ abstracts and contact with experts. We included primary studies on parents of children with CA that studied psychoeducational interventions versus standard care. We assessed the risk of bias using Cochrane Collaboration’s tool.

RESULTS: We included six studies focusing on congenital heart defects (CHD). They described four different psychoeducational strategies. In four studies, statistically significant differences were found. For clinical practice, we considered three interventions as more feasible: the Educational program for mothers, with a group format of four sessions weekly; CHIP-Family intervention, which includes a parental group workshop followed by an individual follow-up booster session; and WeChat educational health program with an online format.

CONCLUSIONS: This review is the first that assesses the impact of psychoeducational interventions targeted at parents of children with CA on their QoL. The best approach to intervention is multiple group sessions. Two essential strategies were to give support material, enabling parents to review, and the possibility of an online program application, increasing accessibility. However, because all included studies focus on CHD, generalizations should be made carefully. These findings are crucial to guide future research to promote and improve comprehensive and structured support for families and integrate them into daily practice.

ABSTRACT

PURPOSE: To estimate the cost-effectiveness of adding a CDK4/6 inhibitor to standard endocrine therapy in the first-line setting for advanced HR+/HER2- breast cancer in postmenopausal and premenopausal women, from the perspective of the Mexican public healthcare system.

METHODS: We used a partitioned survival model to simulate relevant health outcomes in a synthetic cohort of patients with breast cancer derived from the PALOMA-2, MONALEESA-2, MONARCH-3 trials for postmenopausal patients, and from the MONALEESA-7 study for premenopausal patients. Effectiveness was measured in life years gained. Cost-effectiveness is reported through incremental cost-effectiveness ratios (ICER).

RESULTS: In postmenopausal patients, palbociclib led to an increase of 1.51 life years, ribociclib of 1.58 years, and abemaciclib of 1.75 years, compared to letrozole alone. The ICER was 36,648 USD, 32,422 USD, and 26,888 USD, respectively. In premenopausal patients, ribociclib led to an increase of 1.82 life years when added to goserelin and endocrine therapy, with an ICER of 44,579 USD. In the cost minimization analysis, for postmenopausal patients, ribociclib was the treatment with the highest costs due to follow-up requirements.

CONCLUSION: Palbociclib, ribociclib, and abemaciclib demonstrated a significant increase in effectiveness in postmenopausal patients, and ribociclib in premenopausal patients, when added to standard endocrine therapy for patients with advanced HR+/HER2- breast cancer. At the national stablished willingness to pay, only the addition of abemaciclib to standard endocrine therapy in postmenopausal women would be considered cost-effective. However, differences on results between therapies for postmenopausal patients were not statistically significant.

ABSTRACT

INTRODUCTION: This retrospective study investigated major adverse limb events (MALE) and mortality outcomes in critical limb-threatening ischemia (CLTI) patients with tissue loss after an endovascular revascularization-first (EVR-1st) strategy.

METHODS: MALE and mortality were assessed in 157 consecutive patients with CLTI and tissue loss from June 2019 to June 2022 at the Eric Williams Medical Sciences Complex, Trinidad and Tobago.

RESULTS: 157 patients underwent the EVR-1st strategy, of whom 20 were pivoted to immediate surgical revascularization (SR). Of the remaining 137 patients, successful EVR was achieved in 112, giving a procedural success of 82% and an all-comer overall success of 71%. The mortality and MALE rates were 2.7% and 8.9% at 2 years, respectively. Males and patients with previous major amputations were at significantly higher risk for MALE (p values of 0.016 and 0.018, respectively). There was a statistically significant difference in successful EVR for both Rutherford-Baker (RB) 5 (minor) and RB 6 (major) classifications: 63 (56%) vs. 5 (20%) and 49 (44%) vs. 20 (80%), both with a p value of 0.01. There were no differences in successful EVR amongst Wound, Ischemia, Foot Infection (WIfI) clinical stages. There were no differences in successful EVR amongst the Trans-Atlantic Inter-Society Consensus (TASC II) classifications.

CONCLUSIONS: This study may prove clinically informative and applicable for an EVR-1st management strategy for high-risk patients with CLTI in a limited-resource, Caribbean setting.

ABSTRACT

PURPOSE: Glare visual acuity and contrast sensitivity are important indicators of visual quality. Studies have shown that the glare visual acuity and contrast sensitivity in dry eye patients tend to degenerate, further affecting their quality of life. The objective of this study was to investigate the effect of notch filters on glare VA and contrast sensitivity in patients with dry eye or with dry eye syndrome.

METHOD: 36 subjects in the 20‒65 age group were diagnosed as having dry eye disease or perceived dry eye syndromes themselves who were included after the initial screening with the OSDI questionnaire, and one was subsequently excluded as they had undergone retinal detachment surgery. Finally, 35 subjects (14 male and 21 female) with a mean age of 40.66 ± 15.62 years participated in this study. All subjects wore their habitual prescriptions and four different filter lenses (namely 480, 620, dual 480 & 620 notch filter, and FL-41 tinted lens), and measured the parameters of glare visual acuity and contrast sensitivity using CSV-1000 and sine wave contrast test (SWCT), respectively. Student t-test and Repeated measurement analysis (R-ANOVA) were utilized by using SPSS 26.0 software.

RESULTS: A dual-wavelength 480 & 620 nm optical notch filter had a significant anti-glare effect decreasing glare disabilities or discomfort, and leading to better visual quality, the same effect was also shown on a 480 nm notch filter lens. All participants showed a significant difference among the baseline, three notch filters (480 nm, 620 nm, dual-wavelength 480 & 620 nm), and FL-41 tinted lens were used on SWCT_A (1.5 cpd, F = 3.054, p = 0.019) and SWCT_E (18 cpd, F = 2.840, p = 0.049); but did not show statistical different on SWCT_B (3 cpd, F = 0.333, p = 0.771), SWCT_C (6 cpd, F = 1.779, p = 0.159), and SWCT_D (12 cpd, F = 1.447, p = 0.228). The baseline showed the best visual performance on CS at a low spatial frequency (SWCT_A, 1.5 cpd), any filter might reduce the contrast sensitivity at low spatial frequencies in the clinical trial, whereas 480 nm notch filter showed the best effectiveness on CS at a high spatial frequency (SWCT_E, 18 cpd), the FL-41 lens that also filters out the 480 nm band does not achieve the same effect. Moreover, patients with dry eye or those older than 40 years old preferred optical multilayer notch filters to FL-41 tinted lenses.

CONCLUSION: The 480- & 620-nm dual-wavelength and 480-nm single-wavelength notch filters have the best effect on the glare visual acuity and contrast sensitivity (CS) at high spatial frequencies in dry eye patients. The 620-nm notch filter performs better in CS at low and mid-low spatial frequencies; the FL-41 tinted lens performs poorly for glare VA and CS spatial frequencies examination. Patients with glare disabilities or CS disturbance at high spatial frequencies may choose a 480-nm notch filter lens, and patients who have CS disturbance at low spatial frequencies may consider a 620-nm notch filter for the prescription.

ABSTRACT

OBJECTIVE: This cross-sectional study aimed to investigate the association between the occipital spur length and craniofacial morphology in individuals with occipital spur (OS).

METHODS: The study included cephalometric images from 451 individuals (196 females, 255 males, age range was 9-84 years). The spur length and craniofacial characteristics were evaluated using cephalograms. Based on spur length, subjects were divided into two groups: the OS group (N = 209) and the enlarged occipital spur (EOS) group (N = 242). Descriptive statistics, Independent T-test, Mann-Whitney U test, chi-square test, Kruskal-Wallis test, and age- and sex-based stratified analyses were performed. The level of significance was set at p < 0.05.

RESULTS: Males had significantly larger spur length than females. Spur length was shorter in individuals under 18 than the groups over 18. After adjusting for gender and age, ramus height, mandibular body length, effective length of maxilla, effective length of mandible, anterior cranial base length, posterior cranial base length, anterior facial height, posterior facial height, facial height index, and lower anterior facial height had statistically significant differences between OS group and EOS group.

CONCLUSIONS: Males exhibit greater spur length than females. Patients under 18 had a shorter spur length than adults. Linear craniofacial measurements were found to be greater in subjects with EOS than the individuals with OS. The craniofacial growth and development of an individual might be associated with EOS. The causal relationship between EOS and craniofacial development requires further longitudinal studies.

ABSTRACT

PURPOSE: To investigate the effect of technology-assisted Anterior Cruciate Ligament Reconstruction (ACLR) on post-operative clinical outcomes and tunnel placement compared to conventional arthroscopic ACLR.

METHODS: CENTRAL, MEDLINE, and Embase were searched from January 2000 to November 17, 2022. Articles were included if there was intraoperative use of computer-assisted navigation, robotics, diagnostic imaging, computer simulations, or 3D printing (3DP). Two reviewers searched, screened, and evaluated the included studies for data quality. Data were abstracted using descriptive statistics and pooled using relative risk ratios (RR) or mean differences (MD), both with 95% confidence intervals (CI), where appropriate.

RESULTS: Eleven studies were included with total 775 patients and majority male participants (70.7%). Ages ranged from 14 to 54 years (391 patients) and follow-up ranged from 12 to 60 months (775 patients). Subjective International Knee Documentation Committee (IKDC) scores increased in the technology-assisted surgery group (473 patients; P = 0.02; MD 1.97, 95% CI 0.27 to 3.66). There was no difference in objective IKDC scores (447 patients; RR 1.02, 95% CI 0.98 to 1.06), Lysholm scores (199 patients; MD 1.14, 95% CI – 1.03 to 3.30) or negative pivot-shift tests (278 patients; RR 1.07, 95% CI 0.97 to 1.18) between the two groups. When using technology-assisted surgery, 6 (351 patients) of 8 (451 patients) studies reported more accurate femoral tunnel placement and 6 (321 patients) of 10 (561 patients) studies reported more accurate tibial tunnel placement in at least one measure. One study (209 patients) demonstrated a significant increase in cost associated with use of computer-assisted navigation (mean 1158€) versus conventional surgery (mean 704€). Of the two studies using 3DP templates, production costs ranging from $10 to $42 USD were cited. There was no difference in adverse events between the two groups.

CONCLUSION: Clinical outcomes do not differ between technology-assisted surgery and conventional surgery. Computer-assisted navigation is more expensive and time consuming while 3DP is inexpensive and does not lead to greater operating times. ACLR tunnels can be more accurately located in radiologically ideal places by using technology, but anatomic placement is still undetermined because of variability and inaccuracy of the evaluation systems utilized.

LEVEL OF EVIDENCE: Level III.
