Abstract
The prevalence of overweight and obesity has continued to increase globally, and one-size-fits-all dietary recommendations may not be suitable for different individual characteristics. A personalized nutrition intervention may be a potential solution. This review aims to evaluate the effects of the technology-delivered personalized nutrition intervention on energy, fat, vegetable, and fruit intakes among adults with overweight and obesity. A three-step comprehensive search strategy was performed from 10 databases and seven clinical registries in published and unpublished trials. A total of 46 randomized controlled trials (RCTs) involving 19,670 adults with overweight and obesity from 14 countries are included. Subgroup and meta-regression analyses were conducted. Meta-analyses showed a reduction of energy intake (-128.05, 95% CI: -197.08, -59.01) and fat intake (-1.81% energy/days, 95% CI: -3.38, -0.24, and -0.19 scores, 95% CI: -0.40, 0.02) in the intervention compared with the comparator. Significant improvements in vegetable and fruit intakes with 0.12-0.15 servings/day were observed in the intervention. Combined one- and two-way interactions had a greater effect on energy intake reduction compared with their counterparts. Meta-regression analyses revealed that no significant covariates were found. Given that the certainty of the evidence was rated as low or very low, further well-designed RCTs with long-term follow-up are warranted.

Abstract
OBJECTIVES To examine the effectiveness of near-infrared light devices (NIR) on procedure time of successful cannulation, success rate at the first attempt, and pain scores among pediatric patients and explore potential covariates on the intervention effect. BACKGROUND Pediatric patients have encountered a high failure rate as compared with adult patients using traditional cannulation. NIR devices might help to access veins with an optimum viewing area and eliminate the number of attempts. However, methodological limitations and inconsistent results from previous reviews were found. METHODS A three-step comprehensive search was performed in nine databases. Meta-analysis, subgroup, and meta-regression analyses were conducted. Individual quality assessment and certainty of evidence were assessed using the Cochrane risk of bias tool and the Grading of Recommendations, Assessments, Development, and Evaluation criteria, respectively. RESULTS We included 18 randomized controlled trials (RCTs) with 5298 children and adolescents across nine countries. NIR light devices significantly reduce -29.43 s of procedure time and -0.47 attempts of peripheral intravenous cannulation compared with traditional methods. Subgroup analysis observed a significantly large effect size on procedure time using AccuVein with pre-procedure training at the clinics. However, NIR light devices do not significantly decrease the procedure time, first attempt success rate, and pain scores. Meta-regression identified sample size as a significant covariate that had an impact on the success rate at the first attempt. CONCLUSIONS The near-infrared light device can statistically significantly reduce the procedure time and the number of attempts. Given the low or very low certainty of the evidence, future well-designed RCTs are necessary.

Abstract
INTRODUCTION Acceptance and commitment therapy (ACT) is increasingly being studied as a treatment for smoking cessation. However, its immediate, short-, and long-term effects have rarely been reviewed. METHODS This systematic review aimed to evaluate the effectiveness of immediate, short-, medium-, and long-term smoking cessation rates in ACT and comparators at less than 3-month, 3 to 4-month, 6-, and 12-month follow-ups. Randomized controlled trials (RCTs) were searched in eight databases until April 20, 2023. We assessed the quality of RCTs and the certainty of evidence of outcomes. RESULTS Nineteen RCTs involving 7885 smokers across six countries were included. The majority (72.81%) of RCTs were graded as low risk across six domains. For complete-case outcomes, meta-analyses were conducted, and the results revealed a significant effect in favor of ACT [risk ratio: 1.70-1.80 at <3-month, 3 to 4-month, and 6 months follow-up] compared with comparators. For outcomes using missing data management, meta-analyses found an overall effect in favor of ACT, but a significant effect was found at 3 to 4-months only. However, 12-month follow-ups revealed no significant reduction in smoking cessation for both outcomes. Moderate and substantial heterogeneities were found among four meta-analyses that may lead to inaccurate estimates of effects. The certainty of evidence of all outcomes was rated as low and very low. CONCLUSION ACT may be an effective intervention for smoking cessation with immediate, short-term, and medium-term effects. Caution must be applied in the interpretation of the results due to the limited trials and low certainty of evidence. IMPLICATION ACT can be implemented adjuvant to the usual treatment for smoking cessation. Additional RCTs with follow-up data using biochemically verified measures in non-US countries are warranted.

Abstract
OBJECTIVE Smell impairment affects 60-80 per cent of individuals aged over 80 years. This review aimed to identify any association between vitamin D deficiency and smell impairment, and determine the efficacy of vitamin D to treat smell impairment. METHODS A literature search was conducted across four databases between the years 2000 and 2022. The literature screen was performed by two independent reviewers. RESULTS Seven articles were included in this review. Four studies examined the association between vitamin D deficiency and smell impairment, with three studies identifying a significant relationship. Three studies investigated the use of vitamin D as treatment for smell impairment, which found complete resolution or significant symptom improvement after vitamin D deficiency was treated. CONCLUSION This review identified limited studies on this topic. As vitamin D supplementation is relatively cost-efficient, further large-scale studies should be carried out to investigate the efficacy of vitamin D for treating anosmia.

Abstract
CONTEXT A growing number of systematic reviews with meta-analyses have examined the effectiveness of time-restricted eating (TRE) in reducing weight and improving fasting blood glucose and lipid profiles. However, mixed results have been found, and its effectiveness remains uncertain. OBJECTIVE This umbrella review aimed to summarize systematic reviews that (1) examine the effects of TRE on weight loss, fasting blood glucose, total cholesterol, triglycerides, high-density-lipoprotein cholesterol (HDL-C) and low-density-lipoprotein cholesterol (LDL-C) in individuals with overweight and obesity; and (2) compare the effect sizes on these outcomes between conventional TRE and Ramadan fasting. DATA SOURCES A total of 11 databases were searched from inception until March 11, 2022. DATA EXTRACTION Two independent reviewers performed article selection, data extraction, and quality assessment. DATA ANALYSIS Seven systematic reviews with 30 unique meta-analyses involving 7231 participants from 184 primary studies were included. The quality of each review was evaluated as moderate (14.3%) or critically low (85.7%) according to the Assessment of Multiple Systematic Reviews 2. The degree of overlap was rated as slight for all outcomes (corrected cover area = 1.04%-4.27%). Meta-analyses at the meta-data level suggest that TRE is beneficial for reducing weight (P = .006) and fasting blood glucose (P < .01). Meta-analyses at the primary study level suggest that the effect on LGL-C was significant (P = .03). Subgroup analyses revealed greater effects in lowering fasting blood glucose, total cholesterol, and LDL-C from Ramadan fasting than from conventional TRE. The credibility of evidence was rated as suggestive (3.3%), weak (36.7%) or nonsignificant (60%) using a classification method. CONCLUSION TRE may complement usual care and reduce body weight and fasting blood glucose. Rigorous randomized controlled trials with long-term assessments in a wide range of populations are warranted. SYSTEMATIC REVIEW REGISTRATION PROSPERO registration no. CRD42022325657.

Abstract
ABSTRACTEvidence about the effects of digital health interventions (DHIs) on the psychological outcomes of perinatal women is increasing but remains inconsistent. An umbrella review was conducted to (1) assess the effect of DHIs on depressive, anxiety and stress symptoms and (2) compare the effects of DHIs on different digital platforms and population natures. Ten databases were searched from inception until December 23, 2022. The Hartung-Knapp-Sidik-Jonkman random-effects meta-analyses were utilised. Methodological quality was evaluated using the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2). Twenty-four systematic reviews with 41 meta-analyses involving 45,509 perinatal women from 264 primary studies were included. The credibility of the evidence of meta-analyses was rated as highly suggestive (4.88%), suggestive (26.83%), weak (51.22%) or non-significant (17.07%) according to AMSTAR-2. Our findings suggest that DHIs are beneficial for reducing stress symptoms. However, conflicting effects were found on anxiety symptoms. Subgroup and meta-regression analyses suggested that DHIs effectively improve depressive symptoms in postnatal women, and DHIs using the website platform are highly effective in stress reduction. DHIs can be implemented adjuvant to usual obstetric care to improve depressive and stress symptoms. Additional well-designed RCTs with long-term follow-up are warranted.

Abstract
Introduction
5% of forearm fractures in children have associated supracondylar fractures, hence any forearm fractures warrant careful examination of the elbow, and radiographs taken should visualise the elbow and wrist joint for other injuries. We report a case of multiple upper limb fracture in a child, comprising of lateral condyle and both-bone forearm fracture.
Case Presentation:
A 5-year-old boy was admitted having fallen from a ladder approximately 1.5 metres high in a playground. The left limb was significantly deformed, with no open injury, and neurovascularly intact throughout. Radiographs demonstrated a minimally displaced lateral condyle fracture of the left elbow, a mid-shaft ulna fracture and a displaced off-ended distal third radius and ulna fracture of the left wrist. Any metabolic bone disease and non-accidental injury was ruled out. CT imaging was performed to completely assess the fracture pattern and discussion with our local regional trauma centre. Given the minimal displacement of the lateral epicondyle, conservative management was decided for this. The displaced distal radial fracture was managed with open reduction and internal fixation with a plate, and the ulna shaft fracture with manipulation and plaster cast application. By 12 weeks after surgery there was full range of movement of the elbow, wrist, and forearm, with complete radiological union.

Abstract
Abstract
Introduction
Intraoperative neuromonitoring (IONM) is widely used in spinal surgery as it has been shown to be highly sensitive and specific for detecting neurological injuries, although recent evidence has been conflicting in its cost-utility. The authors aim to determine whether the use of IONM during spinal surgeries significantly improves patient outcomes in terms of neurological events, and whether IONM is cost-effective.
Method
Literature search of studies looking at use of IONM for spinal surgeries from 2009 to 2020 was performed across several databases, following PRISMA guidelines. Quality of articles was assessed using MINORS criteria.
Results
The random effects model was used to evaluate the 5 studies comparing neurological events with and without IONM use. There was a higher incidence of neurological events without IONM, at 44 compared to 11 with IONM. However, pooled odds ratio was 0.56 (p = 0.11), indicating no significant difference. IONM was also found to be associated with longer operative times and costs, which is not cost-effective based on NICE recommendations.
Conclusions
- This study corroborate previous studies; there is no significant difference in patient outcome of neurological events with the use of IONM. There is, however, a higher incidence of neurological events without IONM.

Abstract
Abstract
Introduction
We have implemented a VFC model during the COVID-19 pandemic to minimise the number of face-to-face consultations and the risk of transmission.
Method
The VFC was implemented and assessed using 3 PDSA cycles. Initially, a paper referral system was introduced along with treatment pathways. Subsequently an electronic referral system was established. The 3rd PDSA cycle involved training A&E staff on referrals and treatment pathways. At each stage the number of VFC referrals and clinic follow-ups were measured. Patient satisfaction was assessed using a telephone survey with a random sample of 30 patients.
Results
There was a statistically significant reduction in face-to-face follow-ups between pre-VFC (Total:4083, Average:86.87) and post-VFC (Total:713, Average:35.65) p-value<0.0001. There was a statistically significant increase in patient satisfaction after the implementation of the electronic referral system and staff re-training(9.25) compared to paper referrals(8.23), p-value=0.02064.
Conclusions
Our study demonstrated that the VFC successfully reduced the number of face-to-face follow-ups while maintaining patient satisfaction. Thus, it is an effective alternative to conventional fracture clinics. A similar model can be introduced at other hospitals to minimise in-person consultations and risk of transmission, while standardising patient care. It has also highlighted the importance of appropriate technological infrastructure, staff training and service evaluation.

Abstract
The National Health Service (NHS) is currently facing a financial crisis with a projected deficit of £2billion by the end of financial year 2015/16. As operating rooms (OR) are one of the costliest components in secondary care, improving theatre efficiency should be at the forefront of efforts to improve health service efficiency. The objectives of this study were to characterize the causes of trauma OR delays and to estimate the cost of this inefficiency. A 1-month prospective single-centre study in St. Mary's Hospital. Turnaround time (TT) was used as the surrogate parameter to measure theatre efficiency. Factors including patient age, ASA score and presence of surgical and anaesthetic consultant were evaluated to identify positive or negative associations with theatre delays. Inefficiency cost was calculated by multiplying the time wasted with staff capacity costs and opportunity costs, found to be £24.77/minute. The commonest causes for increased TT were delays in sending for patients (50%) and problems with patient transport to the OR (31%). 461 min of delay was observed in 12 days, equivalent to loss of £951.58/theatre/day. Non-statistically significant trends were seen between length of delays and advancing patient age, ASA score and absence of either a senior clinician or an anaesthetic consultant. Interestingly, the trend was not as strong for absence of an anaesthetic consultant. This study found delays in operating TT to represent a sizable cost, with potential efficiency savings based on TT of £347,327/theatre/year. Further study of a larger sample is warranted to better evaluate the identified trends. Delays in operating turnaround time result in substantial financial waste. Causes of delays are reported in this study. Trends between age, ASA score and senior clinician presence with delays were found. Resolving this issue could potentially save an estimated £350,000/theatre/year.
