Managing the work stress of inpatient nurses during the COVID-19 pandemic: a systematic review of organizational interventions

BackgroundDuring the coronavirus disease 2019 (COVID-19) pandemic, inpatient nurses faced various work stressors. Little is known about organizational interventions that can mitigate the negative consequences of pandemic-related stressors.ObjectiveThe aim was to provide a synopsis of the literature concerning the types and outcomes of organizational interventions performed during the COVID-19 pandemic that directly (re)organized the work structures of inpatient nurses to address pandemic-related work stressors or to increase nurses’ ability to cope.MethodsWithin this preregistered systematic literature review, we searched four databases (PubMed, PsycINFO, PsycARTICLES, CINAHL) and two preprint databases (MedRxiv, PsyArXiv) for interventional studies of organizational interventions published between 01/2020 and 03/2023 (k = 990 records). We included 12 primary studies after title-abstract and full-text screening. A synthesis of results without meta-analysis was conducted. Risk of bias was assessed with the Cochrane risk-of-bias tool for randomized trials – version 2 (RoB-2) and Risk Of Bias In Non-randomized Studies - of Interventions (ROBINS-I) tool.ResultsAll interventions were implemented in hospitals. The reasons given for implementation included pandemic-related work stressors such as a high workload, understaffing, and a lack of medical resources. To respond to the various work stressors, half of the studies took a multilevel approach combining organizational and person-oriented interventions (k = 6). Most studies (k = 8) took a secondary prevention approach, focusing on the organization of rest breaks (k = 5). With respect to outcomes, the studies examined nurse-related stress and resilience, turnover intention, job satisfaction, and other factors. Risk-of-bias analyses revealed that conclusions about the effectiveness of the interventions are limited due to confounding factors and self-selection.ConclusionsThe identified interventions provide a basis for future research to draw conclusions on the effectiveness of organizational interventions during pandemics. The promotion of adequate work breaks could be useful if the work stressors associated with strain and negative consequences cannot be changed directly. However, the same stressors (e.g., high workload) can hinder nurses from participating in offered interventions. This emphasizes the importance of directly addressing inpatient nurses’ work stressors.RegistrationProspero-ID CRD42023364807 (March 2023).

Indocyanine green and methylene blue dye guided sentinel lymph node biopsy in patients with penile cancer (PeCa): results of 50 inguinal basins assessed at a single institution in India.

The primary aim of this study was to validate the reliability, sensitivity and safety profile of novel combination of ICG- methylene blue dye as an SN tracer for PeCa. This is a validation and non-randomised prospective observational study involving 25 patients (50 inguinal basins) who underwent SLNB where in ICG and methylene blue were used for localisation. The patients with clinically node negative groins were recruited in the study. SNs were identified intraoperatively using near infrared fluorescence imaging (NIRF Imaging system, SPY-PHI, Stryker, Sweden) and blue dye. The numbers of SNs identified by each tracer and the rates of complications and nodal recurrence during the followup. Overall 137 SNs were identified intraoperatively. Among the 137 SNs excised fluorescence, blue dye and Combined (blue + green) identified 57(41.6%), 27 (19.7%), and 51 (37.2%), respectively. The average number of SLNs removed per patient was 5 (range, 1-11) with sentinel lymph nodes detection rate at 94% (47/50). Seven patients had malignancy on SLNB and underwent ipsilateral radical inguinal lymphadenectomy. One patient had false negative SN and positive node in modified inguinal lymphadenectomy specimen. No adverse events were observed in all cases. The Novel combination of ICG fluorescence-Methylene blue dye technique is simple, reliable and safe. Moreover, it demonstrates a high SLN detection rate with a low false-negative rate, and it avoids radiation exposure.

A Comparison of Postoperative Outcomes Based on Muscle versus Fasciocutaneous Flaps in Scalp Reconstruction: A Systematic Review and Meta-analysis.

Scalp reconstruction in plastic and reconstructive surgery often necessitates the transfer of soft-tissue flaps to restore form and function. The critical decision lies in choosing between muscle-containing (MC) and fasciocutaneous (FC) flaps for scalp reconstruction, and while both variants have their merits, flap composition remains a subject of ongoing debate. This scientific discussion aims to explore this contentious issue through a comprehensive meta-analysis, shedding light on the rationale behind the choice of these flaps and the potential impact on clinical outcomes. A comprehensive systematic review was conducted following PRISMA-P guidelines, encompassing six prominent databases up to the year 2023. Data were collected from studies assessing outcomes of MC and FC flaps for scalp reconstruction. Quality evaluation was performed using ASPS criteria and the ROBINS-I tool. Statistical analysis included descriptive statistics, meta-analysis, sensitivity analysis, and assessment of bias using STATA software. The meta-analysis included 28 nonrandomized studies, totaling 594 flaps (MC: 380, FC: 214). MC flaps were significantly larger than FC flaps. There were no significant differences in flap loss, flap necrosis, or wound dehiscence between the two flap types. However, the incidence of venous congestion was significantly higher in FC flaps. Sensitivity analysis confirmed the robustness of results, and publication bias assessment showed no significant evidence of bias. While both MC and FC flaps offer viable options for scalp reconstruction, the choice should be tailored to individual patient characteristics and defect size. FC flaps may provide advantages such as shorter operative times and reduced morbidity, whereas MC flaps could be preferred for addressing larger defects. Future research should focus on prospective studies and strategies to mitigate venous congestion in FC flaps, enhancing their safety and efficacy in scalp reconstruction.

A systematic review on the techniques, long-term outcomes, and complications of partial breast irradiation after breast-conserving surgery for early-stage breast cancer.

To evaluate the efficacy and safety of four techniques of partial breast irradiation (PBI) including interstitial brachytherapy (ISBT), balloon-based brachytherapy (BBT), Intraoperative radiotherapy (IORT) and three-dimensional conformal radiotherapy (3DCRT) in the treatment for early-stage breast cancer patients after breast-conserving surgery. A systematic search was performed according to the Preferred Reporting Items of Systematic Reviews and Meta-analyses (PRISMA) guidelines using the PubMed, Embase, Cochrane Library and Web of Science databases. The inclusion criteria were clinical trials and observational studies that reported on outcome measures of principal PBI techniques. The methodological quality of the included research data was assessed using bias risk assessment tool with the Methodological Index for Non-Randomized Studies (MINORS), and the research information were analyzed using data analysis software. Clinical studies were collected from the earliest available date until September 2023. Fifty-one studies were included, with a total sample size of 7708. The results of network meta-analysis (NMA) showed that ISBT can lower the local recurrence (SUCRA: 73.8%). In terms of reducing distant metastasis, 3DCRT may be the best choice (SUCRA: 52.5%). And IORT has the highest 5-year overall survival (SUCRA: 90%). Furthermore, ISBT also has the advantages of lowest risk with fat necrosis (SUCRA: 72.5%), infection (SUCRA: 78.3%) and breast pain (SUCRA: 86.2%). BBT may be the optimal solution for fibrosis (SUCRA: 76.9%) and hyperpigmentation (SUCRA: 66.7%). 3DCRT has lower incidence of telangiectasia (SUCRA: 56.7%) and better cosmetic result (SUCRA: 85%). Postoperative PBI treatment using ISBT after breast-conserving surgery in patients with early-stage breast cancer may be a more valuable choice based on the treatment efficacy and is associated with fewer late side-effects. Large-scale, prospective, long-term studies are warranted to clarify the role of different PBI techniques in selected patients.

Comparison of manual versus automated thermal lid therapy with expression for meibomian gland dysfunction in patients with dry eye disease.

To compare two types of lipid expression procedures to treat dry eye disease. Standardized treatment and evaluation methods were used in patients treated with either manual thermoelectric lipid expression (MiBoFlo) or automated lipid expression (Lipiflow) of the Meibomian glands. This was a contemporaneous, non-randomized study of both treatment methods. Treatment was per the manufacturers' recommendation. The primary outcome included two types of dry eye questionnaires as well as objective analysis of ocular surface including tear break up time, Schirmer testing, Osmolarity, and fluorescein staining. Baseline characteristics analyzed included floppy lid, conjunctivochalasis and lagophthalmos. Statistical analysis was performed correcting for baseline factors such as age and co existing pathology using multivariable analysis. Both treatments improved the results of the OSDI and SPEED dry eye questionnaire results. Both treatments resulted in improvement of many objective findings including SPK, lissamine green staining and tear break up time with the MiBoFlo showing more improvement than Lipiflow. OSDI was more sensitive to improvement of symptoms than the SPEED questionnaire. Manual expression with MiBoFlo device resulted in statistically more improvement in questionnaire scores than did automated expression with Lipiflow. Negative prognostic factors for symptomatic improvement included blepharitis, autoimmune disease and ocular allergies. Thermal lid therapy along with mechanical expression of lipids from the meibomian glands successfully treats dry eye symptoms and signs. Manual therapy with MiBoFlo resulted in more subjective and objective improvement scores than automated therapy with the Lipiflow device.

Integrating randomized controlled trials and non-randomized studies of interventions to assess the effect of rare events: a Bayesian re-analysis of two meta-analyses

BackgroundThere is a growing trend to include non-randomised studies of interventions (NRSIs) in rare events meta-analyses of randomised controlled trials (RCTs) to complement the evidence from the latter. An important consideration when combining RCTs and NRSIs is how to address potential bias and down-weighting of NRSIs in the pooled estimates. The aim of this study is to explore the use of a power prior approach in a Bayesian framework for integrating RCTs and NRSIs to assess the effect of rare events.MethodsWe proposed a method of specifying the down-weighting factor based on judgments of the relative magnitude (no information, and low, moderate, serious and critical risk of bias) of the overall risk of bias for each NRSI using the ROBINS-I tool. The methods were illustrated using two meta-analyses, with particular interest in the risk of diabetic ketoacidosis (DKA) in patients using sodium/glucose cotransporter-2 (SGLT-2) inhibitors compared with active comparators, and the association between low-dose methotrexate exposure and melanoma.ResultsNo significant results were observed for these two analyses when the data from RCTs only were pooled (risk of DKA: OR = 0.82, 95% confidence interval (CI): 0.25–2.69; risk of melanoma: OR = 1.94, 95%CI: 0.72–5.27). When RCTs and NRSIs were directly combined without distinction in the same meta-analysis, both meta-analyses showed significant results (risk of DKA: OR = 1.50, 95%CI: 1.11–2.03; risk of melanoma: OR = 1.16, 95%CI: 1.08–1.24). Using Bayesian analysis to account for NRSI bias, there was a 90% probability of an increased risk of DKA in users receiving SGLT-2 inhibitors and an 91% probability of an increased risk of melanoma in patients using low-dose methotrexate.ConclusionsOur study showed that including NRSIs in a meta-analysis of RCTs for rare events could increase the certainty and comprehensiveness of the evidence. The estimates obtained from NRSIs are generally considered to be biased, and the possible influence of NRSIs on the certainty of the combined evidence needs to be carefully investigated.

Menopausal Hormone Therapy in Breast Cancer Survivors.

Menopausal symptoms negatively impact quality of life in breast cancer survivors. The paucity of data on the impact of Menopausal Hormone Therapy (MHT) on oncological outcomes in these patients limits informed clinical discussion. Defining the risk of cancer recurrence with MHT is central to the appraisal of risk/benefit, particularly with low-risk disease (based on genomic profile). The aim of this review is to summarize the current data evaluating MHT in breast cancer patients. A systematic review of the literature was performed to evaluate the impact of MHT on oncological outcomes in breast cancer survivors. Three major databases (PubMed, EMBASE and Medline) were searched. The review included all prospective studies published in English. Four randomized control trials and four non-randomized prospective studies were identified. An increase in breast cancer recurrence with MHT was observed in the early randomized trials whilst no increased risk of recurrence was reported in the observational studies. There remains a need to quantify MHT-related recurrence risk in patients with molecularly favorable disease.

High mortality rate and restricted mobility in above knee amputation following periprosthetic joint infection after total knee arthroplasty: A systematic review.

To systematically review the literature on the outcomes of above knee amputation as a salvage procedure after periprosthetic joint infection in total knee arthroplasty. This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Medline, Scopus, Web of Science, and Embase electronic databases were utilized to identify all studies evaluating clinical outcomes of patients with above knee amputation following PJI from inception to June 24, 2023. Studies were excluded for failure to report functional outcomes specifically related to AKA in PJI following TKA, utilizing surgical interventions other than amputation, AKA indicated for other reasons than PJI, technical studies, conference abstracts, case reports and non-English language. The quality of studies was assessed with the Methodological Index for Non-Randomized Studies (MINORS) criteria. Seven retrospective studies, categorized as Therapeutic Level III evidence, were analyzed, involving a total of 188 patients who underwent AKA following PJI after TKA. The findings consistently indicate that post-AKA, patients experienced a notable decline in their level of independence and reported worsening ambulatory status. Infection and wound complications were common post-AKA, leading to revision surgeries, while the mortality rate ranged from 9 to 50% in the included studies. Polymicrobial organisms were frequently found in pre-AKA PJI, with MRSA being a common causative organism. AKA due to PJI following TKA is associated with restricted mobility and high mortality rate. Polymicrobial infections and MRSA were identified as common infecting organisms, emphasizing the complexities and challenges associated with managing these infections. The reported functional outcomes, ambulatory status, complications, reoperations, and mortality rates highlight the importance of providing comprehensive, individualized care to these patients.

Impact of a health literacy sensitive model of care in outpatient nephrology dietetic clinics.

Inadequate health literacy in people with chronic kidney disease is associated with poorer disease management and greater complications. Adherence to the renal diet is known to be suboptimal and patient feedback about the renal diet suggests that patients leave nephrology clinics feeling confused. The present study aimed to evaluate the impact of a health literacy sensitive model of care (MOC) in outpatient nephrology dietetic clinics. This quasi-experimental non-randomised pre-post study recruited adults attending three renal dietitian clinics. The revised MOC consisted of a renal diet question prompt sheet, teachback, and plain language materials and instructions. Outcomes assessed included clinical, dietary, patient-reported satisfaction and quality of life. Differences between and within groups were analysed using paired t-tests, independent sample t-tests (or non-parametric equivalent), chi-squared and McNemar's tests. Linear mixed models evaluated change in total diet quality score, fruit, vegetable, protein and dairy intake with time as a fixed effect and a random subject specific effect. Fail to attend rates at the initial appointments were lower in the revised MOC (21.5% vs. 9.1%). The revised MOC was associated with significantly improved fruit (p = 0.03) and vegetable (p = 0.003) intake and an improved proportion with adequate diet quality (p = 0.03). These impacts were of moderate effect size (d = 0.5, 95% confidence interval = 0.0-1.0). The revised MOC was also associated with greater satisfaction at baseline (p = 0.04) and higher acceptability scores for all questions at the review appointments. Quality of life improved clinically but not significantly in the revised MOC (p = 0.92). This low-cost health literacy sensitive intervention is a promising strategy to improve fruit and vegetable intake in adults attending renal dietitian clinics. Further research to determine fidelity of teachback use and cost utility analysis would be beneficial. Larger scale trials powered to detect changes in quality of life would also be informative.

An embedded qualitative study of the experiences of people with dementia, their caregivers and volunteer older adults who participated in the CREST resilience-building psychosocial intervention

BackgroundA novel Complex REsilience-building psychoSocial intervenTion (CREST) targeted at people with dementia, their informal carers, general practitioners and the wider community with the aim of increasing resilience and strengthening the personal attributes or external assets of people with dementia living at home, in the community, was developed. It included three components: cognitive stimulation therapy (CST), physical exercise and dementia education. A non-randomised feasibility study was conducted of the CREST intervention, the aim of which was to inform the design of a future randomised controlled trial. This article presents the findings from the qualitative component of the CREST intervention feasibility study, describing the experience of the people with dementia and their caregivers who participated and the volunteer older adults who supported the intervention.MethodsA descriptive qualitative research approach using semi-structured interviews was undertaken. Key stakeholders (people with dementia (n = 9), their caregivers (n = 9) and the volunteer older adults from the physical exercise component (n = 9)) were interviewed about the intervention and the perceived impact of their participation.ResultsThe social aspect of the CREST intervention proved to be important for all three groups. Attendance remained high throughout the intervention. The people with dementia spoke positively about their participation in the CST and exercise components of the CREST intervention. The caregivers liked receiving coping strategies focused on how to communicate better with the person they cared for and how to better manage their own self-care and they liked the group element of the programme. The volunteer older adults supported the people with dementia in taking part in the exercise component, motivating them to do the exercises and helping with social interaction within the group. The volunteers gained exposure to the illness and as a result understood more about dementia and felt better equipped to communicate and deal with people with dementia.ConclusionParticipation in the CREST intervention produced a positive impact on all three groups. The social element of the intervention was noted by everybody and was regarded as being beneficial. Qualitative insights emphasised the value of embedding qualitative research within feasibility studies to inform future intervention design. Further research should focus on conducting a full-scale randomised controlled trial to evaluate CREST’s effectiveness and explore its application to individuals with more advanced dementia.Trial registrationISRCTN25294519.

Preventing OsteoPorosis in Spinal Cord Injury (POPSCI) Study—Early Zoledronic Acid Infusion in Patients with Acute Spinal Cord Injury

Accelerated sub-lesional bone loss is common in the first 2–3 years after traumatic spinal cord injury (TSCI), particularly in the distal femur and proximal tibia. Few studies have explored efficacy of antiresorptives for acute bone loss prevention post-TSCI, with limited data for knee bone mineral density (BMD) or beyond two years follow-up. An open-label non-randomized study was performed at Royal North Shore Hospital and Royal Rehab Centre, Sydney between 2018 and 2023. An ‘acute interventional cohort’ (n = 11) with TSCI (duration ≤ 12-weeks) received a single infusion of 4 mg zoledronic acid (ZOL) at baseline. A ‘chronic non-interventional cohort’ (n = 9) with TSCI (duration 1–5-years) did not receive ZOL. All participants underwent baseline and 6-monthly blood tests (including CTx and P1NP) and 12-monthly DXA BMD scans (including distal femur and proximal tibia). Participants were predominantly Caucasian and male (mean age 38.4 years). At baseline, the ‘acute’ cohort had higher serum CTx, P1NP and sclerostin concentrations, while the ‘chronic’ cohort had lower left hip and knee BMD. Majority with acute TSCI experienced an acute phase reaction after ZOL (9/11; 82%). In the acute cohort, left hip BMD fell by mean ~ 15% by 48 months. Left distal femoral and proximal tibial BMD declined by mean ~ 6–13% at 12 months and ~ 20–23% at 48 months, with a tendency towards greater BMD loss in motor-complete TSCI. A single early ZOL infusion in acute TSCI could not attenuate rapidly declining hip and knee BMD. Prospective controlled studies are required to establish the optimal strategy for preventing early bone loss after acute TSCI.

User Engagement With mHealth Interventions to Promote Treatment Adherence and Self-Management in People With Chronic Health Conditions: Systematic Review.

There are numerous mobile health (mHealth) interventions for treatment adherence and self-management; yet, little is known about user engagement or interaction with these technologies. This systematic review aimed to answer the following questions: (1) How is user engagement defined and measured in studies of mHealth interventions to promote adherence to prescribed medical or health regimens or self-management among people living with a health condition? (2) To what degree are patients engaging with these mHealth interventions? (3) What is the association between user engagement with mHealth interventions and adherence or self-management outcomes? (4) How often is user engagement a research end point? Scientific database (Ovid MEDLINE, Embase, Web of Science, PsycINFO, and CINAHL) search results (2016-2021) were screened for inclusion and exclusion criteria. Data were extracted in a standardized electronic form. No risk-of-bias assessment was conducted because this review aimed to characterize user engagement measurement rather than certainty in primary study results. The results were synthesized descriptively and thematically. A total of 292 studies were included for data extraction. The median number of participants per study was 77 (IQR 34-164). Most of the mHealth interventions were evaluated in nonrandomized studies (157/292, 53.8%), involved people with diabetes (51/292, 17.5%), targeted medication adherence (98/292, 33.6%), and comprised apps (220/292, 75.3%). The principal findings were as follows: (1) >60 unique terms were used to define user engagement; "use" (102/292, 34.9%) and "engagement" (94/292, 32.2%) were the most common; (2) a total of 11 distinct user engagement measurement approaches were identified; the use of objective user log-in data from an app or web portal (160/292, 54.8%) was the most common; (3) although engagement was inconsistently evaluated, most of the studies (99/195, 50.8%) reported >1 level of engagement due to the use of multiple measurement methods or analyses, decreased engagement across time (76/99, 77%), and results and conclusions suggesting that higher engagement was associated with positive adherence or self-management (60/103, 58.3%); and (4) user engagement was a research end point in only 19.2% (56/292) of the studies. The results revealed major limitations in the literature reviewed, including significant variability in how user engagement is defined, a tendency to rely on user log-in data over other measurements, and critical gaps in how user engagement is evaluated (infrequently evaluated over time or in relation to adherence or self-management outcomes and rarely considered a research end point). Recommendations are outlined in response to our findings with the goal of improving research rigor in this area.

Internet-based cognitive behavioral therapy for individuals with gambling disorder in Indonesia: protocol for a pilot and feasibility study.

Gambling disorder (GD) has become a wide concern in Indonesia, as many negative consequences arise from this psychiatric condition. Prompt treatment with an appropriate method of delivery is required to achieve optimal outcomes in GD patients. This protocol paper outlines a study to determine the effectiveness, acceptability, and feasibility of internet-based cognitive behavioral therapy (iCBT) in treating GD in Indonesia. This non-randomized pilot and feasibility study will recruit 20 people with GD. All participants will receive the iCBT intervention through self-learning videos and guided weekly group sessions. The effectiveness of the intervention will be assessed at baseline (week 0), post- treatment completion (week 10), and 6 weeks post-treatment (week 16). The outcomes measured will be the change in gambling symptoms, gambling urges, cognitive distortions, readiness to change, emotional problems, and quality of life of the participants. The feasibility of iCBT for GD patients in Indonesia will be assessed by this study. The study's results will give an indication of the acceptability of the intervention and the feasibility of a subsequent conclusive trial. The delivery of iCBT may help to address the issue of treatment access in an extensive geographical region and provide immediate implications as a treatment resource for GD in practice.

Prognostic Factors and Outcome Measures After Rituximab Therapy in Central Nervous System Vasculitis: A Systematic Review.

Given the growing popularity of Rituximab (Rmab) treatment as a potential substitute for cyclophosphamide, we conducted this review to determine aspects related to Rmab therapy in central nervous system vasculitis (CNSV) patients, aiming to establish both the beneficial and detrimental consequences of Rmab while providing clinical guidance for managing patients' conditions. This systematic review was prepared following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The PubMed, Web of Science, and Scopus databases were utilized to investigate Rmab treatment in CNSV from January 2015 to May 2024. The research question was structured using the Population, Intervention, Comparison, Outcome, and Study Design (PICOS) criteria. Case series with only three or more unique cases, prospective or retrospective non-randomized studies, and randomized controlled trials (RCTs) were addressed. The initial evaluations were performed in PubMed, Scopus, and Web of Science. After removing duplicate entries, 177 publications were obtained, and 41 were chosen for full-text assessment. The review then incorporated information gathered from 27 studies, including 4 case series, 15 non-randomized cohorts, and 8 RCTs. Rmab is generally regarded as effective for CNSV therapy. Given its success, induction Rmab therapy is now frequently employed as maintenance therapy for CNSV patients. Rmab is a viable option for the induction of remission and maintenance treatment, with a successful reduction in relapse rates.

Impact of patient's sex on groin hernia repair: A systematic review and meta-analysis.

Groin hernia repair (GHR) is a performed procedure worldwide, with approximately 20million surgeries carried out each year. Despite being less common in females, there is a lack of research on how sex influences the outcomes of GHR. This systematic review and meta-analysis aim to assess how patient sex impacts results in GHR. We performed a systematic review and meta-analysis according to Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. We searched for studies up to October 2023 in MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials. The studies included focused on sex outcomes for both robotic and open GHR procedures. Data extraction and quality assessment were conducted using the Risk of Bias in Non-Randomized Studies - Of Interventionstool. Our statistical analysis was performed using the metafor package in RStudio. After screening a total of 3917 articles, we identified 29 studies that met our criteria, comprising a total of 1,236,694 patients. Among them, 98,641 (7.98%) patients were females. Our findings showed that females had higher rates of hernia recurrence (RR 1.28), chronic pain (RR 1.52), and surgical site infections (SSIs) (RR 1.46) compared to males. Females showed a lower tendency to undergo minimally invasive surgery (MIS) with a relative risk of 0.82 (95% CI 0.69-0.97; p=0.02). Females tend to face higher rates of complications after GHR such as an elevated risk of chronic pain, recurrence, and surgical site infections (SSI). Moreover, they undergo fewer MIS options compared to males. These results underscore the importance of research to enhance outcomes for women undergoing GHR.

Oligometastatic Urothelial Cancer and Stereotactic Body Radiotherapy: A Systematic Review and an Updated Insight of Current Evidence and Future Directions.

Stereotactic body radiation therapy (SBRT) is the most commonly used metastasis-directed therapy (MDT) for oligometastatic urothelial carcinoma (omUC). Despite efforts in defining this disease entity, open questions remain concerning the role of MDT and the use of biomarkers, imaging, and its combination with systemic therapies. The aim of the present systematic review is to provide an updated overview of the current clinical evidence on SBRT for omUC in terms of survival and local control benefits. We also aim to provide updates on controversial areas and future directions in this emerging field. With a systematic approach, following PRISMA recommendations, we searched two databases to identify and select articles published up until March 2024 reporting the use of SBRT for omUC with or without concomitant systemic therapies. Prospective randomized or non-randomized studies as well as retrospective studies were included. Eight studies were selected for data extraction and 293 omUC patients treated with SBRT were collectively analyzed. In metachronous omUC patients, SBRT delivered with ablative doses (BED10 ≥ 78 Gy) was associated with a 2-year overall survival (OS) rate of 50.7% (95% CI 35.1-64.4%). The use of sub-ablative SBRT doses (BED10 = 43.2 Gy) in combination with immunotherapy did not demonstrate significant clinical outcome improvement in two prospective studies. The overall tolerance was good, with only one study reporting toxicity of grade 3 in up to 18% of the patients treated with SBRT in combination with immunotherapy. SBRT is an effective and widely available MDT option in omUC, although this is based on a limited number of studies. Despite the attempt to use SBRT as an immune response trigger in combination with immunotherapy, no significant improvement in survival outcomes has been observed. The integration of new systemic agents with MDT will likely define a new scenario for the treatment of omUC. The review protocol was registered in PROSPERO, ID: CRD42024522381.

Lip Symmetry After Cleft Lip Repair Fisher in Unilateral Cleft Lip: A Systematic Review

The purpose of this research is to learn the outcomes of lip symmetry after cleft lip repair by Fisher in unilateral cleft lip compared with other techniques. This systematic review searched English full-text available articles in 4 databases: Cochrane, PubMed, ScienceDirect, and Google Scholar, and hand searched through grey literature and reference lists. Subjects were those with unilateral cleft lip without syndromic disorders who had primary cleft lip repair. The authors compared the technique by Fisher with other cleft lip repair techniques. Outcomes were lip symmetry determined quantitatively by lip anthropometric measurement and qualitatively by the Steffensen grading criteria. Four studies were included with a total of 150 cleft lip repairs, comparing the technique by Fisher with techniques by Millard, Mohler, and modified Millard. The 4 studies underwent critical appraisal, data analysis, qualitative synthesis, and meta-analysis. Assessment with Cochrane Risk of Bias 2 for randomized controlled trials and “Risk of Bias in Nonrandomized Studies–of Interventions” for nonrandomized studies displayed an overall high risk of bias in the included studies. “Grading of recommendations, assessment, development, and evaluation” revealed a very low quality of evidence for this review. All 4 studies noted better subjective lip symmetry in the technique by Fisher, but lip and vermilion height were better after the technique by Millard. This review found superior lip symmetry quality but inferior lip symmetry anthropometry after the technique by Fisher compared with the technique by Millard and its modifications, with a low quality of evidence.

Risk Stratification in Nonischemic Dilated Cardiomyopathy Using CMR Imaging

Accurate risk stratification of nonischemic dilated cardiomyopathy (NIDCM) remains challenging. To evaluate the association of cardiac magnetic resonance (CMR) imaging-derived measurements with clinical outcomes in NIDCM. MEDLINE, Embase, Cochrane Library, and Web of Science Core Collection databases were systematically searched for articles from January 2005 to April 2023. Prospective and retrospective nonrandomized diagnostic studies reporting on the association between CMR imaging-derived measurements and adverse clinical outcomes in NIDCM were deemed eligible. Prespecified items related to patient population, CMR imaging measurements, and clinical outcomes were extracted at the study level by 2 independent reviewers. Random-effects models were fitted using restricted maximum likelihood estimation and the method of Hartung, Knapp, Sidik, and Jonkman. All-cause mortality, cardiovascular mortality, arrhythmic events, heart failure events, and major adverse cardiac events (MACE). A total of 103 studies including 29 687 patients with NIDCM were analyzed. Late gadolinium enhancement (LGE) presence and extent (per 1%) were associated with higher all-cause mortality (hazard ratio [HR], 1.81 [95% CI, 1.60-2.04]; P < .001 and HR, 1.07 [95% CI, 1.02-1.12]; P = .02, respectively), cardiovascular mortality (HR, 2.43 [95% CI, 2.13-2.78]; P < .001 and HR, 1.15 [95% CI, 1.07-1.24]; P = .01), arrhythmic events (HR, 2.69 [95% CI, 2.20-3.30]; P < .001 and HR, 1.07 [95% CI, 1.03-1.12]; P = .004) and heart failure events (HR, 1.98 [95% CI, 1.73-2.27]; P < .001 and HR, 1.06 [95% CI, 1.01-1.10]; P = .02). Left ventricular ejection fraction (LVEF) (per 1%) was not associated with all-cause mortality (HR, 0.99 [95% CI, 0.97-1.02]; P = .47), cardiovascular mortality (HR, 0.97 [95% CI, 0.94-1.00]; P = .05), or arrhythmic outcomes (HR, 0.99 [95% CI, 0.97-1.01]; P = .34). Lower risks for heart failure events (HR, 0.97 [95% CI, 0.95-0.98]; P = .002) and MACE (HR, 0.98 [95% CI, 0.96-0.99]; P < .001) were observed with higher LVEF. Higher native T1 relaxation times (per 10 ms) were associated with arrhythmic events (HR, 1.07 [95% CI, 1.01-1.14]; P = .04) and MACE (HR, 1.06 [95% CI, 1.01-1.11]; P = .03). Global longitudinal strain (GLS) (per 1%) was not associated with heart failure events (HR, 1.06 [95% CI, 0.95-1.18]; P = .15) or MACE (HR, 1.03 [95% CI, 0.94-1.14]; P = .43). Limited data precluded definitive analysis for native T1 relaxation times, GLS, and extracellular volume fraction (ECV) with respect to mortality outcomes. The presence and extent of LGE were associated with various adverse clinical outcomes, whereas LVEF was not significantly associated with mortality and arrhythmic end points in NIDCM. Risk stratification using native T1 relaxation times, extracellular volume fraction, and global longitudinal strain requires further evaluation.

The Battle of Endoscopic Bariatric Therapies for Obesity: Endoscopic Sleeve Gastroplasty Versus Endoscopically Inserted Intragastric Balloon—A Pairwise Meta-Analysis of Comparative Studies and a Call for Randomized Controlled Trials

Background: Endoscopic sleeve gastroplasty (ESG) represents the latest primary endoscopic intervention for managing obesity. Both ESG and intragastric balloons (IGBs) have demonstrated effectiveness and safety for weight loss. However, there is a paucity of high-quality evidence supporting the superiority of one over the other, and no pairwise meta-analysis of comparative studies has been published to date. Our aim was to conduct a pairwise meta-analysis of comparative studies directly comparing ESG and IGB. Methods: We systematically conducted a literature search on PubMed and Google Scholar following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Our search used specific search terms. The Risk of Bias in Non-Randomized Studies of Interventions (ROBINS-I) Tool was used to evaluate the quality of the included studies. Data were analyzed using Review Manager (RevMan) 5.4.1 software with a random-effects model. The statistical method used was the Mantel-Haenszel method. For dichotomous data, the effect size was represented using odds ratio (OR), while mean difference (MD) was utilized as the effect size for continuous data. Results: After screening 967 records, a total of 9 studies met the inclusion criteria for this meta-analysis (5302 patients). The quality assessment categorized 5 studies as having a moderate risk of bias, while 3 studies were classified as having a low risk of bias. Sufficient information was not available for one study to ascertain its overall quality. A statistically significant increase in total weight loss percentage (TWL%) at 1 and 6 months was observed with ESG compared with IGB. In addition, a statistically insignificant decrease in the incidence of adverse events and readmissions was observed with ESG. Furthermore, a statistically significant decrease in the incidence of reintervention was observed with ESG. Conclusions: While this study suggests a higher TWL% associated with ESG compared with IGB, drawing definitive conclusions is challenging due to limitations identified during a comprehensive quality assessment of the available literature. We advocate for randomized controlled trials (RCTs) directly comparing the newer IGB (with a 12-mo placement duration) with ESG. However, this study consistently reveals higher rates of early reintervention (re-endoscopy) within the IGB group, primarily necessitated by the removal or adjustment of the IGB due to intolerance. Given the additional intervention required at 6 or 12 months to remove the temporarily placed IGB, this trend may imply that IGB is less economically viable than ESG. Cost-effectiveness analyses comparing ESG and IGB are warranted to provide valuable scientific insights.

Comparing the effectiveness and safety of videolaryngoscopy and direct laryngoscopy for endotracheal intubation in the paediatric emergency department: a systematic review and meta-analysis.

Endotracheal intubation is an uncommon procedure for children in the emergency department but can be technically difficult and cause significant adverse effects. Videolaryngoscopy (VL) offers improved first-pass success rates over direct laryngoscopy (DL) for both adults and children undergoing elective surgery. This systematic review was designed to evaluate current evidence regarding how the effectiveness and safety of VL compares to DL for intubation of children in emergency departments. Four databases (MEDLINE, Embase, CENTRAL and Web of Science) were searched on 11th May 2023 for studies comparing first-pass success of VL and DL for children undergoing intubation in the emergency department. Studies including adult patients or where intubation occurred outside of the emergency department were excluded. Quality assessment of included studies was carried out using the Risk Of Bias In Non-randomised Studies of Interventions (ROBINS-I) tool. Meta-analysis was undertaken for first-pass success and adverse event rate. Ten studies met the inclusion criteria representing 5,586 intubations. All included studies were observational. Significantly greater first-pass success rate was demonstrated with VL compared to DL (OR 1.64, 95% CI [1.21-2.21], p = 0.001). There was no significant difference in risk of adverse events between VL and DL (OR 0.79, 95% CI [0.52-1.20], p = 0.27). The overall risk of bias was moderate to serious for all included studies. VL can offer improved first-pass success rates over DL for children intubated in the emergency department. However, the quality of current evidence is low and further randomised studies are required to clarify which patient groups may benefit most from use of VL. https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=415039, Identifier CRD42023415039.
