Meta-Analysis Review
Iron deficiency (ID) is the most prevalent nutritional deficiency worldwide. Low levels of serum ferritin (SF) could affect the thyroid gland and its functioning. The purpose of this systematic review and meta-analysis is to summarize the main currently available evidence and analyze data on the relationship between ID and thyroid function. This study included all articles evaluating the relationship between ID and thyroid function. Quality assessment was performed using Cambridge Quality Checklists. The search strategy included the following combination of Medical Subjects Headings terms and keywords: "iron deficiency", "thyroid function", "thyroid disease", "thyroid dysfunction", and "hypothyroidism". A meta-analysis was performed to evaluate whether thyroid stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3) levels differed between patients with ID and healthy controls without ID. For statistical comparison between cases and controls, the mean difference (MD) was calculated, and a subgroup analysis of pregnant and non-pregnant women was performed. Cochran's Q testing and heterogeneity indices () were used to assess statistical heterogeneity. Sensitivity analysis and publication bias analyses were also performed, both qualitatively and quantitatively. Finally, a meta-regression analysis was performed to evaluate the correlation between serum TSH or FT4 levels and SF in the study population. Ten cross-sectional studies were identified and reviewed. Patients with ID showed TSH (MD: -0.24 mIU/L; 95% CI -0.41, -0.07; = 100%, = 0.005), FT4 (MD: -1.18 pmol/L; 95% CI -1.43, -0.94; = 99%, < 0.000001), and FT3 (MD: -0.22 pmol/L; 95% CI -0.32, -0.12; = 99%, < 0.00001) levels that were significantly lower. Subgroup analysis confirmed significantly lower TSH, FT4, and FT3 levels in pregnant women. Non-pregnant women showed significantly lower serum FT4 and FT3 levels but no difference in TSH values. Meta-regression analysis showed that serum TSH and FT4 levels were positively correlated with SF levels. Our systematic review of the literature found that ID significantly increases the prevalence of thyroid autoantibody (anti-thyroglobulin antibodies and anti-thyroid peroxidase antibodies) positivity both individually and collectively. Studies currently published in the literature indicate a possible relationship between ID, thyroid function, and autoimmunity, especially in some patient groups. Data analysis shows that thyroid hormone levels are lower in patients with ID and, in particular, in pregnant women. Further studies are needed to understand the role played by iron in thyroid metabolism.

Review
BACKGROUND
With the increasingly demanding healthcare environment, patient safety issues are only becoming more complex. This urges nursing leaders to adapt and master effective leadership; particularly, transformational leadership (TFL) is shown to scientifically be the most successfully recognized leadership style in healthcare, focusing on relationship building while putting followers in power and emphasizing values and vision.
AIM
To examine how transformational leadership affects nurses' job environment and nursing care provided to the patients and patients' outcomes.
DESIGN
A systematic literature review was conducted. From 71 reviewed, 23 studies were included (studies included questionnaire surveys and one interview, extracting barriers and facilitators, and analyzing using qualitative synthesis).
RESULT
TFL indirectly and directly positively affects nurses' work environment through mediators, including structural empowerment, organizational commitment, and job satisfaction. Nurses perceived that managers' TFL behavior did not attain excellence in any of the included organizations, highlighting the necessity for additional leadership training to enhance the patient safety culture related to the non-reporting of errors and to mitigate the blame culture within the nursing environment.
CONCLUSION
Bringing more focus to leadership education in nursing can make future nursing leaders more effective, which will cultivate efficient teamwork, a quality nursing work environment, and, ultimately, safe and efficient patient outcomes. This study was not registered.

Review
The shortage of healthcare workers is a growing concern. The COVID-19 pandemic and retirement wave have accelerated turnover rates. This systematic review aimed to identify and analyse the existing interventions for job retention of healthcare workers, in terms of nurses and physicians, in a hospital setting. A comprehensive search was conducted within three electronic databases, guided by the preferred reporting items for systematic review and meta-analyses (PRISMA) and synthesis without meta-analysis (SWiM) guidelines, this resulted in 55 records that met the inclusion criteria. The intervention outcomes are categorized into substantial themes: onboarding, transition program to a different unit, stress coping, social support, extra staffing, coping with the demands of patient care, work relationships, development opportunities and department resources, job environment, work organization, recruitment approach, and technological innovations. Considering the literature, onboarding programs and mentoring for nurses and physicians are recommended. Additionally, other interventions described in this review could positively affect the retention of nurses and physicians. When selecting an intervention for implementation, managers and human resources should consider the intervention that matches the determinant of intention to leave of their healthcare workers and the hospital's mission, vision, and values. Sharing the success stories of implemented interventions may benefit healthcare organizations.

Meta-Analysis
BACKGROUND
Although there is an assertion that weather conditions affect osteoarthritis (OA) pain, the results from clinical studies remain inconsistent. This meta-analysis was performed to evaluate the association between weather conditions and OA pain.
METHODS
Cochrane Library, Embase, PubMed, and Web of Science were searched from inception to September 30, 2022. Observational studies that explored all weather conditions associated with pain intensity were included. In the systematic review, the methodological quality of the selected studies was assessed and a best-evidence synthesis was used to make qualitative conclusions. Based on homogeneous results, Fisher's scores derived from the effect size of temperature (T), barometric pressure (BP) or relative humidity (RH) related to OA pain were synthesized and further transformed to the correlation coefficients (summary r) in meta-analysis.
RESULTS
A total of 14 studies were included in the best-evidence synthesis of a qualitative systematic review. There was strong evidence with 13 of 14 studies reporting consistent findings that weather factors in general, including any kind of meteorological condition, were associated with OA pain. Subsequently, 3 studies regarding BP or T, and 5 studies regarding RH with the pain of OA were included in quantitative meta-analyses. Both BP (pooled Fisher's = 0.37, 95% CI 0.15 to 0.59; summary = 0.35, 95% CI 0.15 to 0.53) and RH (pooled Fisher's = 0.10, 95% CI 0.01 to 0.18; summary = 0.086, 95% CI -0.05 to 0.22) were positively related to OA pain, while T was negatively related to OA pain (pooled Fisher's = -0.38, 95% CI -0.60 to -0.16; summary = -0.36, 95% CI -0.54 to -0.16).
CONCLUSIONS
In this study, weather factors in general were significantly associated with OA pain. It may provide useful references for the daily health management of OA. More studies designed with the consistent meteorological condition are warranted to validate the findings.KEY MESSAGEMany people with osteoarthritis think their joint pain is affected by the weather, while the association between OA pain and weather conditions is still unclear.This is a systematic review and meta-analysis of 14 observational studies for the association between weather conditions and OA pain.Weather conditions appear to be associated with OA pain. Barometric pressure and relative humidity were positively correlated to OA pain intensity, while temperature was negatively correlated to OA pain.

Meta-Analysis
BACKGROUND
Alcohol consumption may increase blood pressure but the details of the relationship are incomplete, particularly for the association at low levels of alcohol consumption, and no meta-analyses are available for nonexperimental cohort studies.
METHODS
We performed a systematic search of longitudinal studies in healthy adults that reported on the association between alcohol intake and blood pressure. Our end points were the mean differences over time of systolic (SBP) and diastolic blood pressure (DBP), plotted according to baseline alcohol intake, by using a dose-response 1-stage meta-analytic methodology.
RESULTS
Seven studies, with 19 548 participants and a median follow-up of 5.3 years (range, 4-12 years), were included in the analysis. We observed a substantially linear positive association between baseline alcohol intake and changes over time in SBP and DBP, with no suggestion of an exposure-effect threshold. Overall, average SBP was 1.25 and 4.90 mm Hg higher for 12 or 48 grams of daily alcohol consumption, compared with no consumption. The corresponding differences for DBP were 1.14 and 3.10 mm Hg. Subgroup analyses by sex showed an almost linear association between baseline alcohol intake and SBP changes in both men and women, and for DBP in men while in women we identified an inverted -shaped association. Alcohol consumption was positively associated with blood pressure changes in both Asians and North Americans, apart from DBP in the latter group.
CONCLUSIONS
Our results suggest the association between alcohol consumption and SBP is direct and linear with no evidence of a threshold for the association, while for DBP the association is modified by sex and geographic location.

Review
Carpal tunnel syndrome (CTS) is a condition that affects the main nerves in the wrist area that causes numbness, tingling, and weakness in the hand and arm. CTS affects 5% of the general population and results in pain in the wrist due to repetitive use, most commonly affecting women and office workers. Conservative management of CTS includes neurodynamic modulation to promote median nerve gliding during upper limb movements to maintain normal function. However, evidence for the benefits of neurodynamic modulation found disparities, and hence, the effectiveness of neurodynamic modulation remains unclear. This study aimed to systematically review the current evidence from randomized controlled trials (RCTs) to establish the effectiveness of neurodynamic techniques as a non-surgical treatment option for CTS. Using the PRISMA guidelines, two authors searched four electronic databases, and studies were included if they conformed to pre-established eligibility criteria. Primary outcome measures included outcomes from the Boston carpal tunnel syndrome questionnaire, while secondary outcomes included nerve conduction velocity, pain, and grip strength. Quality assessment was completed using the Cochrane RoB2 form, and a meta-analysis was performed to assess heterogeneity. Twelve RCTs met our inclusion/exclusion criteria with assessments on 1003 participants in the treatment and control arms. High heterogeneity and some risks of bias were observed between studies, but the results of the meta-analysis showed a significant reduction in our primary outcome, the Boston carpal tunnel syndrome questionnaire-symptom severity scale (mean difference = -1.20, 95% CI [-1.72, -0.67], < 0.00001) and the Boston carpal tunnel syndrome questionnaire-functional severity scale (mean difference = -1.06, 95% CI [-1.53, -0.60], < 0.00001). Secondary outcomes such as sensory and motor conduction velocity increased significantly, while motor latency was significantly reduced, all positively favoring neurodynamic techniques. Pain was also significantly reduced, but grip strength was not significantly different. Our systematic review demonstrates significant benefits of neurodynamic modulation techniques to treat CTS and specifically that it reduces symptom severity, pain, and motor latency, while at the same time improving nerve conduction velocities. Hence, our study demonstrates a clear benefit of neurodynamic techniques to improve recovery CTS.

Review
Transcutaneous electrical acupoint stimulation (TEAS) is an emerging therapeutic approach that combines the effects of transcutaneous electrical nerve stimulation (TENS) with acupuncture point stimulation. Due to its noninvasive nature, it possesses relative advantages over traditional acupuncture and needle-based electrostimulation. Despite the large number of randomized clinical trials (RCTs) describing the effectiveness of TEAS in different applications, its role and mechanism are still not fully understood. The aim of this study was to systematically compare and summarize the latest studies examining a variety of TEAS applications in clinical practice. Databases, including Medline (PubMed), Cochrane Library and Google Scholar were searched without any time restrictions (as of March 2021). The analysis was performed according to the Cochrane Collaboration criteria. Out of 637 studies, only 22 RCTs were selected. Nine studies evaluated the impact of TEAS on nausea and vomiting (NV), showing beneficial effects compared to standard therapy. Eight RCTs examined the effectiveness of TEAS in pain management, reporting pain alleviation described using the visual analog scale (VAS) and lowering of total opioid doses. Improvement of postoperative recovery, in vitro fertilization and pregnancy outcomes, as well as display of cardioprotective properties were found to positively correlate with TEAS. As a noninvasive modality with advantages over classical acupuncture and needle-based electrostimulation, TEAS may be a valuable tool in clinical practice, particularly for pain and NV management. However, considering the methodological quality of the RCTs, rigorous large-scale clinical trials are required to evaluate the clinical utility of this method.

Meta-Analysis Review
BACKGROUND
Obsessive-compulsive disorder (OCD) is a condition with poor treatment outcomes. Improved understanding of the aetiology can inform prevention and treatment approaches; hence several studies have assessed early maladaptive schemas (EMSs) in OCD. This systematic review and meta-analysis aimed to synthesise the evidence on relationships between the 18 EMSs and OCD.
METHODS
The study was conducted according to PRISMA guidelines and registered on PROSPERO (CRD42022329337). A systematic search of PubMed, PsycINFO, and CINAHL Complete was conducted on 4 June 2022. Studies in peer-reviewed journal articles were included if they assessed EMSs and OCD (diagnosis or symptom severity) in adults with a mean age of 18 years or older. Studies were excluded if they were not in English, did not include original quantitative data, or reported on case studies. Study details were tabulated and the meta-analysis findings were presented using forest plots. Methodological quality was assessed using the Appraisal tool for Cross-Sectional Studies (AXIS).
RESULTS
Based on 22 studies (pooled N = 3699), all 18 EMSs were positively correlated with OCD. The largest associations were with the dependence/incompetence (r = 0.40 95 % CI [0.32, 0.47]), vulnerability to harm or illness (r = 0.40 95 % CI [0.32, 0.48]), and negativity/pessimism schemas (r = 0.42 95 % CI [0.22, 0.58]).
LIMITATIONS
Several meta-analyses showed considerable heterogeneity and publication bias.
CONCLUSIONS
The findings suggest all EMSs, particularly those relating to disproportionate negative expectations and a perceived inability to cope, are implicated in OCD. Psychological prevention and treatment for OCD may benefit from targeting these schemas.

Meta-Analysis
PURPOSE
To report a systematic review and meta-analysis of the association between dry eye disease (DED) and dyslipidaemia.
METHODS
PubMed, Embase, Web of Science and Cochrane Library were systematically searched from January 2000 to December 2021. We included observational studies to assess the correlation of DED with meibomian gland dysfunction and dyslipidaemia without any language restrictions. The pooled OR with 95% CI was calculated in Stata V.15.
RESULTS
Of 6727 identified studies, 18 studies (21 databases) with a total of 2 663 126 patients were analysed in our meta-analysis. The results showed that DED risk was associated with dyslipidaemia (OR=1.53, 95% CI: 1.41 to 1.66, p=0.001), especially elevated total cholesterol levels (OR=1.57, 95% CI: 1.25 to 1.99, p<0.001), elevated low-density lipoprotein cholesterol levels (OR=1.13, 95% CI: 1.06 to 1.20, p<0.001) and high-density lipoprotein cholesterol levels (OR=1.06, 95% CI: 1.01 to 1.11, p<0.001), but not with serum triglyceride levels. Moreover, having a history of lipid-lowering drug use (OR=1.41, 95% CI: 1.19 to 1.67, p<0.001) was also found to be positively associated with DED risk.
CONCLUSIONS
The findings suggested that dyslipidaemia and lipid-lowering drug use might be associated with an increased risk of DED. More evidence is needed to confirm the findings by prospective studies.

Review
BACKGROUND
Despite the extensive volume of research published on checklists in the intensive care unit (ICU), no review has been published on the broader role of checklists within the intensive care unit, their implementation and validation, and the recommended clinical context for their use. Accordingly, a scoping review was necessary to map the current literature and to guide future research on intensive care checklists. This review focuses on what checklists are currently used, how they are used, process of checklist development and implementation, and outcomes associated with checklist use.
METHODS
A systematic search of MEDLINE (Ovid), Embase, Scopus, and Google Scholar databases was conducted, followed by a grey literature search. The abstracts of the identified studies were screened. Full texts of relevant articles were reviewed, and the references of included studies were subsequently screened for additional relevant articles. Details of the study characteristics, study design, checklist intervention, and outcomes were extracted.
RESULTS
Our search yielded 2046 studies, of which 167 were selected for further analysis. Checklists identified in these studies were categorised into the following types: rounding checklists; delirium screening checklists; transfer and handover checklists; central line-associated bloodstream infection (CLABSI) prevention checklists; airway management checklists; and other. Of 72 significant clinical outcomes reported, 65 were positive, five were negative, and two were mixed. Of 122 significant process of care outcomes reported, 114 were positive and eight were negative.
CONCLUSIONS
Checklists are commonly used in the intensive care unit and appear in many clinical guidelines. Delirium screening checklists and rounding checklists are well implemented and validated in the literature. Clinical and process of care outcomes associated with checklist use are predominantly positive. Future research on checklists in the intensive care unit should focus on establishing clinical guidelines for checklist types and processes for ongoing modification and improvements using post-intervention data.
