Evaluation of bevacizumab biosimilar on wound healing complications in patients with colorectal cancer undergoing endoscopic mucosal resection: A systematic review and meta-analysis in anorectal medicine.

Complications related to wound healing pose substantial obstacle in the management of colorectal cancer (CRC), specifically in the field of anorectal medicine. Biosimilars of bevacizumab have emerged as crucial therapeutic agents in the management of these complications. With the particular emphasis on effects of Bevacizumab Biosimilar Plus on wound healing among patients diagnosed with CRC, this review underscores the potential of this anorectal medication to improve patient outcomes and was aimed to assess the safety and efficacy of Bevacizumab Biosimilar Plus in relation to complications associated with wound healing in patients with CRC. The assessment centers on its therapeutic potential and safety profile within the domain of anorectal medicine. In accordance with the PRISMA guidelines, a comprehensive literature search was performed, resulting in the identification of 19 pertinent studies out of an initial 918. Priority was given to assessing the safety and adverse effects of Bevacizumab Biosimilar Plus in conjunction with its effectiveness in wound healing. The extracted data comprised the following: study design, patient demographics, comprehensive treatment regimens, wound healing-specific outcomes and adverse effects. The evaluation of study quality was conducted utilizing the instruments provided by the Cochrane Collaboration and the Newcastle-Ottawa Scale (NOS). Bevacizumab Biosimilar Plus demonstrates efficacy in the management of wound healing complications among patients with CRC, with a safety and efficacy profile similar to that of the original Bevacizumab, according to the analysis. Notably, several studies reported improved rates of wound healing in relation to the biosimilar. The safety profiles exhibited similarities to the anticipated anti-VEGF agent effects. In wound management, the biosimilar also demonstrated advantages in terms of prolonged efficacy. In addition, analyses of cost-effectiveness suggested that the use of biosimilars could result in cost reductions. Bevacizumab Biosimilar Plus exhibited potential as an anorectal medication for the effective management of wound healing complications in patients with CRC. This has substantial ramifications for improving the quality of patient care, encompassing the affordability and effectiveness of treatments.

Use of Social Media in Orthopaedic Surgery Training and Practice: A Systematic Review.

Social media use has grown across healthcare delivery and practice, with dramatic changes occurring in response to the coronavirus (COVID-19) pandemic. The purpose of this study was to conduct a comprehensive systematic review to determine the current landscape of social media use by (1) orthopaedic surgery residencies/fellowship training programs and (2) individual orthopaedic surgeons and the change in use over time. We searched 3 electronic databases (PubMed, MEDLINE, and Embase) from their inception to April 2022 for all studies that analyzed the use of social media in orthopaedic surgery. Two reviewers independently determined study eligibility, rated study quality, and extracted data. Methodology was in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Twenty-eight studies were included, of which 11 analyzed social media use by orthopaedic surgery residency and fellowship training programs and 17 examined its use by individual orthopaedic surgeons. Among residency and fellowship programs, Instagram was identified as the most common platform used, with 42% to 88% of programs reporting program-specific Instagram accounts, followed by Twitter/X (20%-52%) and Facebook (10%-38%). Social media was most commonly used by programs for recruitment and information dissemination to prospective residency applicants (82% and 73% of included studies, respectively). After the start of the COVID-19 pandemic, there was a 620% and 177% increase in the number of training programs with Instagram and Twitter/X accounts, respectively. Individual use of social media ranged from 1.7% to 76% (Twitter/X), 10% to 73% (Facebook), 0% to 61% (Instagram), 22% to 61% (LinkedIn), and 6.5% to 56% (YouTube). Instagram, Twitter/X, and Facebook are the premier platforms that patients, residency applicants, and institutions frequent. With the continued growth of social media use anticipated, it will be critical for institutions and individuals to create and abide by guidelines outlining respectful and professional integration of social media into practice.

A Meta-Analysis of Anxiety Symptoms and Related Factors in Chinese College Students During the COVID-19 Pandemic

Objective: To explore the distribution of anxiety symptoms and related factors among Chinese college students during the COVID-19 pandemic, aiming to provide references for mental health education and management strategies tailored to Chinese college students amidst the pandemic. Methods: Both Chinese and English databases were searched to collect studies on factors related to anxiety symptoms in Chinese college students, along with surveys conducted between January 1st, 2020, and February 1st, 2023. Following the AHRQ cross-sectional study quality evaluation standards, a quality assessment of the included research data was conducted. Meta-analysis was performed using Stata 12. Results: A total of 1,057 references were searched, with 40 studies meeting the inclusion criteria. These studies collectively surveyed 189,005 individuals, among whom 57,456 individuals were found to exhibit anxiety symptoms. The anxiety detection rate was calculated at 25.6% (95% CI: 20.5–30.6%), significantly higher than the anxiety risk detection rate among the general Chinese population (15.8%). Gender, the impact of the pandemic on personal life, and awareness of COVID-19 were identified as factors influencing the detection rate of anxiety among college students. Conclusions: The anxiety levels among Chinese college students during the COVID-19 pandemic were notably severe. Consequently, university personnel should prioritize the mental well-being of these students and implement timely psychological interventions.

Characteristics of Telehealth Interventions for Adult Patients with Chronic Pain and Family Care Partners.

Objectives: This review aimed to assess characteristics of telehealth in pain management for adult patients with chronic pain and their family care partners and review current evidence of the effectiveness of telehealth for pain management. Based on the Revised Symptom Management model, this review identified types of chronic pain management strategies and symptom management outcomes delivered by telehealth. Methods: We conducted a systematic review of four electronic databases, PubMed, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, and Embase, using combinations of keywords, including "telehealth," "caregivers," and "pain." Only interventions delivered online, including websites, mobile applications, phone calls, and videoconferencing, were included. To accurately characterize the features of each telehealth pain intervention, we employed a standardized checklist. Additionally, a summary table of the evidence was created. Results: We analyzed 17 studies that met the inclusion criteria, of which 14 were randomized controlled trials, 1 was a cohort study, and 2 were qualitative cohort studies. We grouped interventions based on content of the intervention for pain management (education, psychotherapy, reporting and consultation, and multicomponent intervention). The quality rating of studies was mostly moderately strong. Findings of interventions' effectiveness were showing heterogenous effects on variables, possibly due to different pain measurements and varying follow-up times. Significance of Results: Telehealth interventions can potentially increase access to care for patients with chronic pain and their families in a limited resource area. Telehealth technology is a feasible tool that may enhance clinicians' pain management efforts for patients with chronic pain and their family care partners. The results of this review can be used to guide telehealth pain assessment and evaluation for care partners, clinicians, and researchers and inform the design of future telehealth systems.

Assessing the Relationship Between Traditional In Vitro Fertilization and Birth Defects: A Systematic Review and Meta-Analysis

Background Previously published meta-analyses revealed that IVF combined with intracytoplasmic sperm injection (ICSI) had an increased risk of birth defects in children. ICSI is more invasive, expensive, and time-consuming than IVF, but both result in comparable live birth rates. Currently, despite traditional IVF being used less frequently nationally and internationally than combined IVF/ICSI, it is important to understand the relationship between traditional IVF and birth defects due to a paucity of literature. Objective This systematic review and meta-analysis focused on whether traditional IVF techniques increase the risk for “all” birth defects and “major” birth defects in singletons compared to naturally conceived children. Search Strategy PubMed and EMBASE databases adhered to PRISMA guidelines. Selection Criteria Study selection consisted of original publications in English reporting birth defects for IVF singletons vs. naturally conceived children. Data Collection and Analysis Nine selected items from STROBE criteria were employed to rate study quality. Random effect models were used to calculate pooled odds ratios. Results From 916 publications, fifteen studies met eligibility criteria. Eight studies were rated as high quality, while the remaining 7 were rated as medium. A higher rate of “all” birth defects (pooled OR= 1.44 (95% CI:1.15-1.80) as well as a higher risk for “major” birth defects (pooled OR= 1.64; 95% CI: 1.24-2.18) were observed among traditional IVF-conceived singletons compared to naturally conceived children. Conclusions This is the first systematic review and meta-analysis to date to provide the highest available evidence that IVF is associated with “all” and “major” birth defects among IVF singletons compared to naturally conceived infants. Future large prospective studies should employ standardized reporting and uniform protocols for identifying birth defects with consistent diagnostic criteria for both minor and major birth defects, and comparable durations of follow-up in order to obtain an accurate estimate of birth defects after IVF.

Ursodeoxycholic Acid Prophylaxis and the Reduction of Gallstone Formation After Bariatric Surgery: An Updated Meta-Analysis of Randomized Controlled Trials.

Gallstone formation following bariatric surgery poses a significant clinical concern, prompting various preventive strategies, including ursodeoxycholic acid (UDCA) prophylaxis. This systematic review and meta-analysis aimed to assess the efficacy of UDCA in preventing gallstone formation after bariatric surgery. A comprehensive literature search was conducted in major databases up to September 2023, identifying 12 randomized controlled trials (RCTs) meeting the inclusion criteria. The studies, spanning from 1993 to 2022, involved 2,767 patients who underwent diverse bariatric procedures. The primary outcome was the overall incidence of cholelithiasis, with secondary outcomes encompassing gallstone occurrences at three, six, and 12 months; symptomatic cholelithiasis; and rates of cholecystectomy. The Cochrane risk-of-bias tool was utilized for evaluating study quality, and statistical analyses were conducted using the RevMan software (Cochrane Collaboration, London, UK). Patients receiving UDCA demonstrated a significantly lower overall incidence of gallstones post-bariatric surgery (risk ratio [RR] 0.13; P < 0.0001). Subgroup analyses confirmed reduced gallstone incidence at three months (P = 0.04), six months (P < 0.00001), and one year (P < 0.00001) with UDCA prophylaxis. Symptomatic cholelithiasis incidence was also lower in the UDCA group (RR 5.70; P < 0.00001), and cholecystectomy rates were significantly reduced (RR 3.05; P = 0.002). This meta-analysis supports the efficacy of UDCA prophylaxis in preventing gallstone formation after bariatric surgery. The findings suggest that UDCA administration not only lowers overall gallstone incidence but also reduces the occurrence of symptomatic cholelithiasis and mitigates the need for cholecystectomy. However, caution is warranted due to heterogeneity, diverse surgical procedures, and limited long-term follow-up in the included studies. Further research with standardized protocols and extended observational periods is recommended to strengthen the evidence base and guide clinical practice.

Fitness-to-drive after adult civilian traumatic brain injury: protocol for a systematic review and meta-analysis.

Traumatic brain injury (TBI) poses significant challenges for assessing fitness-to-drive (FTD) and determining the appropriate timing for return-to-driving (RTD) in civilian adults. This systematic review and meta-analysis protocol is designed to offer a comprehensive assessment of RTD timelines post-TBI, examining the effects of injury severity as well as demographic and clinical factors that influence driving capabilities. In response to gaps identified in previous literature-namely, the absence of recent systematic search strategies and thorough quality assessments-this study employs rigorous methodologies for literature search, data extraction, and evaluation of study quality. Our approach aims to provide reliable estimates and detailed analyses of subgroups within the TBI population. The findings aim to support clinical decision-making, inform RTD readiness, and potentially impact policy and driving assessment protocols. Ultimately, this review seeks to contribute to public safety measures, reduce traffic-related harm, and improve life outcomes for individuals recovering from TBI, thereby filling a vital research niche in neurotrauma rehabilitation.

Evaluating mental health decision units in acute care pathways (DECISION): a quasi-experimental, qualitative and health economic evaluation.

People experiencing mental health crises in the community often present to emergency departments and are admitted to a psychiatric hospital. Because of the demands on emergency department and inpatient care, psychiatric decision units have emerged to provide a more suitable environment for assessment and signposting to appropriate care. The study aimed to ascertain the structure and activities of psychiatric decision units in England and to provide an evidence base for their effectiveness, costs and benefits, and optimal configuration. This was a mixed-methods study comprising survey, systematic review, interrupted time series, synthetic control study, cohort study, qualitative interview study and health economic evaluation, using a critical interpretive synthesis approach. The study took place in four mental health National Health Service trusts with psychiatric decision units, and six acute hospital National Health Service trusts where emergency departments referred to psychiatric decision units in each mental health trust. Participants in the cohort study (n = 2110) were first-time referrals to psychiatric decision units for two 5-month periods from 1 October 2018 and 1 October 2019, respectively. Participants in the qualitative study were first-time referrals to psychiatric decision units recruited within 1 month of discharge (n = 39), members of psychiatric decision unit clinical teams (n = 15) and clinicians referring to psychiatric decision units (n = 19). Primary mental health outcome in the interrupted time series and cohort study was informal psychiatric hospital admission, and in the synthetic control any psychiatric hospital admission; primary emergency department outcome in the interrupted time series and synthetic control was mental health attendance at emergency department. Data for the interrupted time series and cohort study were extracted from electronic patient record in mental health and acute trusts; data for the synthetic control study were obtained through NHS Digital from Hospital Episode Statistics admitted patient care for psychiatric admissions and Hospital Episode Statistics Accident and Emergency for emergency department attendances. The health economic evaluation used data from all studies. Relevant databases were searched for controlled or comparison group studies of hospital-based mental health assessments permitting overnight stays of a maximum of 1 week that measured adult acute psychiatric admissions and/or mental health presentations at emergency department. Selection, data extraction and quality rating of studies were double assessed. Narrative synthesis of included studies was undertaken and meta-analyses were performed where sufficient studies reported outcomes. Psychiatric decision units have the potential to reduce informal psychiatric admissions, mental health presentations and wait times at emergency department. Cost savings are largely marginal and do not offset the cost of units. First-time referrals to psychiatric decision units use more inpatient and community care and less emergency department-based liaison psychiatry in the months following the first visit. Psychiatric decision units work best when configured to reduce either informal psychiatric admissions (longer length of stay, higher staff-to-patient ratio, use of psychosocial interventions), resulting in improved quality of crisis care or demand on the emergency department (higher capacity, shorter length of stay). To function well, psychiatric decision units should be integrated into the crisis care pathway alongside a range of community-based support. The availability and quality of data imposed limitations on the reliability of some analyses. Psychiatric decision units should not be commissioned with an expectation of short-term financial return on investment but, if appropriately configured, they can provide better quality of care for people in crisis who would not benefit from acute admission or reduce pressure on emergency department.

Exploring specialist dementia nursing models and their impact on people living with dementia and their family: A systematic review

AbstractBackgroundEvidence that brings together the attributes, specialist knowledge, skills, and competencies required by specialist dementia nurses to fulfil their role is currently lacking, making it difficult to assess the effectiveness of specialist nurse‐led interventions. We systematically reviewed the evidence for specialist dementia nursing to determine how it is defined in terms of key skills, models of delivery, and the impact on families and people living with dementiaMethodWe searched for papers using three databases (MEDLINE, CINAHL, PsycINFO), grey literature (EThOS), and the National Institute for Health and Care Excellence (NICE) evidence search. Search terms related to ‘specialist nursing’ and ‘dementia’ were used. We screened titles and abstracts of identified articles and conducted forward searches for additional relevant studies. Two authors independently rated study quality. Findings were synthesised narratively.Result31 studies were included in the review; 26 were conducted in the UK or USA using a range of methodologies. Role titles varied to include “Admiral Nurses”, “Nurse Practitioners” and “Clinical Nurse Specialists”. We found limited evidence comparing the knowledge, skills, and competencies required by specialist nurses except Admiral Nursing where these were described in three studies. In RCTs (n = 2), specialist nursing did not improve donepezil adherence; and personalised emails to family carers from a nurse specialist did not increase carer self‐efficacy when compared to less intensive interventions. In non‐randomised studies, a USA Nurse Dementia Care Manager service was associated with fewer emergency room and hospital admissions; there were no differences in clinical or cost outcomes in an Admiral Nursing service; and training inpatient specialist nurses in a behavioural intervention increased use of pain‐ relief medication and reduced patient length of stay. Of the 31 studies, 4 reported high carer satisfaction with specialist nursing.ConclusionWe identified only one framework defining specialist dementia nursing competencies, and limited evidence for effectiveness of specialist nursing dementia services on families affected by dementia, despite care received being highly valued. No RCT has measured the impact of specialist nursing on family carer and client outcomes relative to less specialist care.

Stuttering in individuals with Down syndrome: a systematic review of earlier research.

The main objective of this systematic review was to synthesize the evidence on the occurrence and characteristics of stuttering in individuals with Down syndrome and thus contribute knowledge about stuttering in this population. Group studies reporting outcome measures of stuttering were included. Studies with participants who were preselected based on their fluency status were excluded. We searched the Eric, PsychInfo, Medline, Scopus, and Web of Science Core Collection databases on 3rd January 2022 and conducted supplementary searches of the reference lists of previous reviews and the studies included in the current review, as well as relevant speech and language journals. The included studies were coded in terms of information concerning sample characteristics, measurement approaches, and stuttering-related outcomes. The appraisal tool for cross-sectional studies (AXIS) was used to evaluate study quality. We identified 14 eligible studies, with a total of 1,833 participants (mean = 131.29, standard deviation = 227.85, median = 45.5) between 3 and 58 years of age. The estimated occurrence of stuttering ranged from 2.38 to 56%, which is substantially higher than the estimated prevalence (1%) of stuttering in the general population. The results also showed that stuttering severity most often was judged to be mild-to-moderate and that individuals with Down syndrome displayed secondary behaviors when these were measured. However, little attention has been paid to investigating the potential adverse effects of stuttering for individuals with Down syndrome. We judged the quality of the evidence to be moderate-to-low. The negative evaluation was mostly due to sampling limitations that decreased the representability and generalizability of the results. Based on the high occurrence of stuttering and the potential negative effects of this condition, individuals with Down syndrome who show signs of stuttering should be referred to a speech and language pathologist for an evaluation of their need for stuttering treatment.

Existential distress among family caregivers of patients with advanced cancer: A systematic review and meta-analysis.

Caregiving for a loved one is challenging and requires significant resources. Existential distress in family caregivers may include hopelessness, demoralization, fear of death, pre-loss grief, or a sense of not being emotionally prepared. The aim of this systematic review is to synthesize the quantitative literature on existential distress among family caregivers of patients with advanced cancer, focusing on its prevalence, association with mental disorders, as well as with sociodemographic, disease, and treatment-related factors. We systematically searched electronic databases for quantitative studies of the above-described existential distress concepts in family caregivers of patients with advanced cancer. Two independent reviewers extracted data and evaluated study quality. Data were analyzed using random-effects meta-analysis. We retrieved 17.587 records, of which 31 studies fulfilled inclusion criteria. 63% of the studies (n=20) provided sufficient data for meta-analysis for 5558 patients. We found an overall pooled prevalence of 30.6% for existential distress, 95% CI [24.2-37.0]. For existential distress subconcepts, prevalence rates were 57.0%, 95% CI [37.8-76.2], for death anxiety, 13.9%, 95% CI [10.8-17.0], for demoralization, 24.0%, 95% CI [18.0-30.0], for pre-loss grief, 18.4%, 95% CI [4.0-32.7], for hopelessness, 35.2%, 95% CI [28.2-42.2], for loneliness, and 35.6%, 95% CI [13.0-58.3], for emotional unpreparedness. Approximately one third of the respondents were affected by high levels of existential distress. The review provides evidence for further development of support services that can reduce existential distress, focused on death anxiety, and improve the quality of life for family caregivers of patients with advanced cancer.

SciRAPnano: a pragmatic and harmonized approach for quality evaluation of in vitro toxicity data to support risk assessment of nanomaterials.

Large amounts of nanotoxicity data from alternative non-animal (in vitro) test methods have been generated, but there is a lack of harmonized quality evaluation approaches for these types of data. Tools for scientifically sound and structured evaluation of the reliability and relevance of in vitro toxicity data to effectively inform regulatory hazard assessment of nanomaterials (NMs), are needed. Here, we present the development of a pragmatic approach to facilitate such evaluation. The tool was developed based on the Science in Risk Assessment and Policy (SciRAP) tool currently applicable to quality evaluation of chemical toxicity studies. The approach taken to develop the tool, referred to as SciRAPnano, included refinement of the original SciRAP in vitro tool through implementation of identified NM-relevant criteria, and further refined based on a set of case studies involving evaluation of 11 studies investigating in vitro toxicity of nano-sized titanium dioxide. Parameters considered cover key physicochemical properties as well as assay-specific aspects that impact NM toxicity, including NM interference with test methods and NM transformation. The final SciRAPnano tool contains 38 criteria for reporting quality, 19 criteria for methodological quality, and 4 guidance items to evaluate relevance. The approach covers essential parameters for pragmatic and harmonized evaluation of NM in vitro toxicity studies and allows for structured use of in vitro data in regulatory hazard assessment of NMs, including transparency on data quality.

Extracorporeal Membrane Oxygenation in Pregnant and Postpartum Women With Critical Coronavirus Disease 2019 (COVID-19) Acute Respiratory Distress Syndrome: A Systematic Review and Meta-analysis.

To estimate the maternal survival and live-birth rates in pregnant women with acute respiratory distress syndrome (ARDS) secondary to critical coronavirus disease 2019 (COVID-19) who are treated with extracorporeal membrane oxygenation (ECMO) by performing a systematic review and meta-analysis. From database inception through August 2023, we explored MEDLINE, Web of Science, EMBASE, CINAHL, ClinicalTrials.gov, and Cochrane Central Register of Controlled Trials. Studies reporting maternal survival and live-birth rates in pregnant women with critical COVID-19 undergoing ECMO were included. Two reviewers separately ascertained studies, obtained data, and evaluated study quality. Summary estimates of maternal survival and live-birth rates were measured, and 95% CIs were calculated. Nine retrospective case series and 12 retrospective cohort studies were identified with 386 pregnant women with critical COVID-19 who underwent ECMO. Studies evaluated women that were treated from January 2020 to October 2022. Four studies were from the United States; three were from Turkey; two were from France; two were from Israel; and one each was from Columbia, Germany, Italy, Kuwait, Poland, Republic of Srpska, the United Arab Emirates, the United Kingdom, a consortium from Belgium, France, Switzerland, and an international registry. The pooled estimate of the maternal survival rate among pregnant patients who were initiated on ECMO was 75.6% (95% CI, 66.0-84.1%, I2 =72%). The pooled estimate of the live-birth rate among pregnant patients who were initiated on ECMO was 83.7% (95% CI, 76.8-89.6%, 153 neonates, I2 =11%). When the case series and cohort studies were examined separately, the results were similar. Among pregnant women with acute respiratory distress syndrome attributable to critical COVID-19 who were managed with ECMO, maternal survival and live-birth rates were high.

Patient satisfaction following robotic unicompartmental knee arthroplasty: A systematic review and meta-analysis.

Unicompartmental knee arthroplasty (UKA) is a viable alternative to total knee arthroplasty (TKA) for osteoarthritis patients with single-compartment involvement, with advantages including accelerated recovery, reduced pain, and improved function. Robotic-assisted UKA (rUKA) is a promising development that ensures precise implant positioning and limb alignment. However, concerns about complications remain. This study looks at patient satisfaction as a key metric for determining the efficacy of rUKA versus manual UKA (mUKA). The search strategy for this study followed PRISMA. Using precise keywords, PubMed, Scopus, Web of Science, and the Cochrane library were searched. English articles were searched until August 2, 2023. Selection criteria included mUKA and rUKA patient satisfaction studies. The NOS scale evaluated study quality. Meta-analysis was done with R and heterogeneity analysis. This systematic review examined 5 studies with 1060 UKAs (532 robotic-assisted and 528 manual). Variable satisfaction assessment methods were used. Three studies found no difference in patient satisfaction after robotic-assisted UKA, but two found a higher satisfaction. Meta-analysis showed robotic-assisted UKA improved patient satisfaction (OR = 1.72 [1.25-2.37]). Overall, most studies showed low risk of bias, except one with higher bias. This review suggests that robotic assistance may enhance patient satisfaction in UKA procedures.

Comparison of the diagnostic value of 18F-NaF PET/CT and 99mTc-MDP SPECT for bone metastases: a systematic review and meta-analysis.

Bone scintigraphy, the standard tool for detecting bone metastases has some insufficiencies; thus, supplementary imaging techniques are needed. This study is a comprehensive meta-analysis of studies reporting and comparing the diagnostic efficacy of 18F-sodium fluoride (18F-NaF) positron emission tomography/computed tomography (PET/CT) and 99mTc-MDP single-photon emission computed tomography (SPECT) for bone metastases. Literature related to the diagnosis of bone metastases using 18F-NaF PET/CT and 99mTc-MDP SPECT was searched on PubMed, EMBASE, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang databases, and VIP. Evaluation of study quality was performed according to Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2). Pooled sensitivity (SEN) and specificity (SPE) were assessed along with heterogeneity. The subject operating characteristic curve was plotted, the area under the curve (AUC) was calculated, and the pre- and post-test probabilities were compared. Finally, 11 articles, consisting of 1,085 patients and 1,782 lesions, were included. At the patient level (11 articles), the results were pooled SEN =0.92 and SPE =0.96 for PET/CT, SEN =0.80 and SPE =0.90 for SPECT. The AUC of PET/CT [0.98 (0.96-0.99)] was higher than that of SPECT [0.92 (0.89-0.94), P<0.05]. At the lesion level (6 articles), the results were pooled SEN =0.96 and SPE =0.98 for PET/CT, SEN =0.76 and SPE =0.94 for SPECT. The AUC of PET/CT [0.99 (0.98-1.00)] was higher than that of SPECT [0.94 (0.92-0.96); P<0.05]. Statistical heterogeneity existed, and meta-regression showed that, at patient-based level, the study design type, tumor character, and the selection blinding method were the main sources of heterogeneity. Furthermore, both PET/CT and SPECT had superior SEN for osteogenic metastases than non-osteogenic metastases (P=0.01). At the lesion level, tumor character was a source of heterogeneity accompanied by an increased SEN for osteogenic metastases, and the SEN for SPECT combined with CT was improved [SEN =0.87 (0.68-1.00), P=0.03]. 18F-NaF PET/CT has a higher SEN and SPE than 99mTc-MDP SPECT in diagnosing bone metastases, nevertheless, it is necessary to fully understand the primary tumor and the characteristics of the imaging protocol to choose suitable modality for individuals. Combining SPECT with CT improves the diagnostic efficacy than having SPECT alone and can be a powerful supplement to PET/CT for suspected osteogenic bone metastases.

Hemoglobin as a prognostic marker for neurological outcomes in post-cardiac arrest patients: a meta-analysis

The aim of this study was to investigate the relationship between serum level of hemoglobin and neurological outcomes following cardiac arrest. Relevant studies were identified by searching electronic databases including PubMed, Web of Science, Cochrane Library, and Embase from June 2012 through April 2023. Articles were rigorously reviewed for their study inclusion and exclusion criteria. Pooled effect date was determined using the standardized mean difference (SMD) and 95% confidence intervals (CI). The Newcastle–Ottawa Scale was used to evaluate study quality. Subgroup analyses were conducted to determine confounding factors affecting patient outcomes. Study heterogeneity, sensitivity, and publication bias were also determined.This meta-analysis included 11 studies involving 2519 patients. Our results suggest that high serum level of hemoglobin may improve neurological prognosis(SMD = 0.60, 95%CI = 0.49–0.71, I2 = 10.85). The findings of this study indicate that serum level of hemoglobin may be associated with better neurological prognosis, perhaps an appropriate increase in serum haemoglobin levels can improve the neurological prognosis of patients in cardiac arrest.

Maternal gestational diabetes mellitus and the childhood asthma in offspring: a meta-analysis

BackgroundMaternal diabetes might be related to a high risk of allergic disease in offspring. However, it remains unknown if maternal gestational diabetes mellitus (GDM) is also associated with a high incidence of childhood asthma in offspring. A systematic review and meta-analysis was performed to investigate the above association.MethodsRelevant observational studies were obtained by search of electronic databases including Medline, Embase, Cochrane Library, and Web of Science. A randomized-effects model was selected to pool the data by incorporating the influence of potential heterogeneity. The Newcastle-Ottawa Scale was used for study quality evaluation. Subgroup analyses were performed to evaluate the potential influences of study characteristics on the outcome.ResultsTen datasets from seven moderate to high quality cohort studies, involving 523,047 mother-child pairs were included in the meta-analysis. Overall, maternal GDM was associated with a higher risk of childhood asthma in offspring (risk ratio [RR]: 1.22, 95% confidence interval [CI]: 1.07 to 1.39, p = 0.003; I2 = 30%). Subgroup analyses showed that the association was not significantly affected by study design, validation methods for GDM, or diagnostic strategy for asthma (p for subgroup analyses all > 0.05). The association between maternal GDM and asthma in offspring was more remarkable after adjusting maternal body mass index in early pregnancy (RR: 1.50 versus 1.06, p < 0.001), but significantly weakened after adjusting hypertensive disorders during pregnancy (RR: 1.08 versus 1.50, p = 0.001).ConclusionsMaternal GDM may be associated with an increased incidence of childhood asthma in offspring.

Glycemic Variability and the Risk of Diabetic Peripheral Neuropathy: A Meta-Analysis.

Glycemic variability (GV) has been related to complications in patients with diabetes. The aim of the systematic review and meta-analysis was to investigate whether GV is also associated with the incidence of diabetic peripheral neuropathy (DPN). A systematic search of Medline, Web of Science, Embase, and Cochrane Library database was conducted to identify relevant observational studies with longitudinal follow-up. The Newcastle-Ottawa Scale was used for study quality evaluation. A random-effects model was utilized to pool the results, accounting for heterogeneity. Ten observational studies including 72 565 patients with diabetes were included. The quality score was 8-9, indicating generally good quality of the included studies. With a mean follow-up duration of 7.1 years, 11 532 patients (15.9%) were diagnosed as DPN. Compared to patients with low GV, patients with high GV were associated with an increased risk incidence of DPN (risk ratio: 1.51, 95% confidence interval: 1.23 to 1.85, p<0.001; I2=78%). In addition, subgroup analysis showed consistent results in patients with type 1 and type 2 diabetes, and in studies evaluating the short-term and long-term GV (p for subgroup difference=0.82 and 0.53). Finally, results of subgroup analysis also suggested that the association between GV and risk of DPN were not significantly affected by study design, follow-up durations, diagnostic methods for DPN, adjustment of mean glycated hemoglobin A1c, or study quality scores (p for subgroup difference all>0.05). A high GV may be associated with an increased incidence of DPN.

Interobserver Reliability of the Paris Classification for Superficial Gastrointestinal Tract Neoplasms: A Systematic Review.

The Paris classification characterizes the morphology of superficial gastrointestinal tract neoplasms. This system has been shown to predict the risk of submucosal invasion in certain subtypes of lesions. There is limited data that assesses its agreement amongst endoscopists. We performed a systematic review to summarize the available literature on the interobserver reliability (IOR) of the Paris classification. We conducted a search through December 2020 for studies reporting IOR of the Paris classification. Studies were included if they quantitatively evaluated the IOR of the Paris classification with at least five participating endoscopists. Two authors independently screened studies and abstracted data using an a priori-designed data collection form. Evaluation of study quality and risk of bias was performed using an adapted version of the Guidelines for Reporting Reliability and Agreement Studies. Of the 1,541 studies retrieved, 5 were included in the review. All studies were observational cohort studies published between 2014 and 2020. The IOR of the Paris classification was moderate amongst all four studies evaluating colorectal neoplasms (range, κ = 0.42 to κ = 0.54) and substantial in one study that evaluated gastric neoplasms (κw = 0.65). An educational intervention was conducted by three studies with variable methodology and no significant change in IOR. IOR of the Paris classification is moderate for superficial colonic neoplasms. Further study is needed to determine the reliability of this system for superficial gastric lesions. Standardized training programs are required to investigate the impact of educational intervention on the Paris classification amongst endoscopists.

Quality Assessment of Studies Evaluating Cognitive Behavioural Therapy for Insomnia in Populations with PTSD: A Systematic Review

Objective: This systematic review aims to evaluate the quality of intervention studies assessing CBT-I in adult populations with PTSD. Specifically examining overall quality, specific design elements and trends over time. Method: n &gt; 1 studies assessing CBT-I in adult populations with PTSD were included. The Randomized Controlled Trial - Psychotherapy Quality Rating Scale (RCT-PQRS) was used to evaluate study quality. Correlations between overall study quality and publication year were calculated. Results: Nine studies were included. Overall, study quality was rated as moderate. Six design elements were not addressed adequately in most studies. No significant correlation was found. Conclusions: The evidence base is of moderate quality. However, several specific design elements limit their conclusions. Strategies to minimize limitations are discussed.
