Incidence and outcomes of transient new-onset atrial fibrillation complicating acute coronary syndromes: results from a systematic review and meta-analysis

Abstract Background The overall risk of long-term adverse events of a transient episode of new-onset atrial fibrillation (AF) in patients with acute coronary syndrome (ACS) remains uncertain. This meta-analysis aimed to assess the prognostic impact of transient new-onset AF complicating ACS. Methods and results Cohort studies examining the risk of adverse events in patients with transient new-onset AF compared to those in sinus rhythm after ACS were identified through a comprehensive search of MEDLINE, Scopus, Cochrane, and Google Scholar Library. Studies reporting the incidence of ischaemic stroke events, recurrent AF, or all-cause mortality at the longest follow-up were included. Adjusted hazard ratios (aHRs) with 95% confidence intervals (CI) were synthesized using inverse variance-weighted random-effects meta-analysis. In the seven observational studies included, comprising 151 735 patients, 6 597 (4.3%) experienced transient new-onset AF, which was associated with an increased risk of ischaemic stroke, recurrent AF, or all-cause mortality (HR: 2.24, 95% CI: 1.75–2.85; P < 0.0001; I2 = 30.76%; seven studies). The results remained consistent across each individual endpoint, including ischaemic stroke (HR 2.38, 95% CI: 1.64–3.44; P < 0.01; I2 = 50.2%; five studies), recurrent AF (HR 4.68, 95% CI: 2.07–10.59; P = 0.0002; I2 = 50.2%; four studies), and all-cause mortality (HR 1.36, 95% CI: 1.08–1.71; P = 0.0089; I2 = 53.25%; four studies). Meta-regression analyses revealed a significant increase in these adverse events associated with ST-elevation myocardial infarction (P = 0.001), while there was a tendency for their decrease associated with oral anticoagulant prescription at discharge (P = 0.07). Conclusions The occurrence of transient new-onset AF is associated with an elevated long-term risk of stroke, recurrent AF, and all-cause mortality in patients with ACS. Consequently, these data urge randomized clinical trials to assess the best antithrombotic regimen while potentially helping the current treatment decision-making process for these patients.

Limb-girdle muscular dystrophies: A scoping review and overview of currently available rehabilitation strategies.

Limb-girdle muscular dystrophies (LGMDs) constitute a diverse group of inherited disorders primarily affecting skeletal muscle. Despite the absence of cures, rehabilitative treatments offer potential for preventing and mitigating loss of muscle strength. However, the role of exercise training in LGMD patients remains contentious. This review aims to provide an overview of the currently available motor rehabilitation strategies for the most common subtypes of LGMD. To identify relevant articles, we performed a systematic search in PubMed, Embase, Cochrane Library, and Web of Science, focusing on muscular and respiratory interventions. The search resulted in 560 potentially relevant articles, of which 16 were included in the review. Eight studies concentrated on neuromuscular functional rehabilitation therapy programs, seven combined both neuromuscular rehabilitation and interventions to maintain or enhance respiratory functionality and one focused on respiratory intervention only. Altogether, the papers examined offered a comprehensive view on the rehabilitative strategies available and provided an indication of the most valuable practices to deal with patients' health and needs. Upon analysis, we conclude that, when tailored to individual needs, muscle training can enhance strength and functional abilities, positively impacting psychological well-being. However, generic protocols may lead to limited benefits, fatigue, pain, and compliance issues. Moreover, early management of respiratory symptoms and personalized respiratory physiotherapy can enhance patients' well-being and their capability to participate in muscle training exercises. Future studies should not only refine rehabilitation approaches but also assess their impact on patients' quality of life, including psychological factors like depression and self-esteem.

Chemical neurolysis of genicular nerves for chronic non-cancer knee pain: A scoping review.

Chemical neurolysis of the genicular nerves is a treatment option for intractable non-cancer knee pain. This scoping review synthesizes the available literature on the effectiveness, adverse effects and procedural techniques of chemical neurolysis of genicular nerves for the management of knee pain. Scoping review. All clinical and research settings. Adult participants with chronic non-cancer knee pain undergoing chemical neurolysis of genicular nerves. A literature search in MEDLINE, EMBASE and Cochrane Library was conducted up to 4 September 2023. Articles were searched via terms and keywords relating to "knee", "pain", "knee osteoarthritis", "ablation", "alcohol", "phenol" and "chemical neurolysis". Included articles were full text primary studies and in English. Data was extracted using an electronic database by 2 independent reviewers. There were 8 studies included in this review (including 1 randomized controlled trial), comprising 192 patients. There were 4 studies that used phenol, 3 studies that used alcohol, and 1 study that used either alcohol or phenol for chemical neurolysis. Both fluoroscopy and/or ultrasound guidance were utilized for nerve target identification. All studies demonstrated that chemical neurolysis resulted in improved pain and/or functional outcomes, with no serious adverse events reported. Chemical neurolysis of the genicular nerves is a promising treatment strategy for chronic knee pain. Interpretation of the available studies are limited by study heterogeneity and small sample sizes. High-quality randomized controlled trials are required to clarify the selection of appropriate nerve targets, choice of image guidance, and to compare with other ablative modalities.

Prevalence and predictors of malaria in pregnant women in Sub-Saharan Africa: a systematic review and meta-analysis

Malaria remains a significant threat to pregnant women in sub-Saharan Africa. This systematic review and meta-analysis aims to estimate the prevalence and identify predictors of malaria infection among pregnant women in the region. Following preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, a comprehensive search of PubMed Central, Google Scholar, EMBASE, ScienceDirect, and Cochrane Library was conducted, including 15 studies published between 2013 and 2023. The pooled prevalence of malaria, calculated using a random-effects model, was 19.0% (95% CI: 0.13-0.26), with heterogeneity (I²=81.9%) reflecting geographical and climatic diversity. Prevalence rates ranged from 6.4% in Burkina Faso to 36.4% in Tanzania. Asymptomatic cases had a prevalence of 19.0% (95% CI: 0.10-0.38), while symptomatic cases were slightly lower at 17.0% (95% CI: 0.12-0.23). Predictors of malaria included maternal age, parity, insecticide-treated net usage, intermittent preventive treatment, trimester-specific risk, and education level. These findings underscore the need for targeted, context-specific interventions to mitigate malaria risk among pregnant women in sub-Saharan Africa and inform effective malaria control strategies.

Metastatic glioblastoma multiforme on skin and subcutaneous tissue

Glioblastoma multiforme (GBM) is characterized by its infiltrative growth pattern and high recurrence rate despite treatment. While local progression within the central nervous system (CNS) is the rule, manifestations outside the CNS, particularly skin and subcutaneous metastases, are very infrequent and seldom reported in the literature. The authors reviewed the current understanding of this rare condition, with the main purpose of giving visibility to its clinical presentation and prognostic implications, thus improving clinical management and encouraging research in this area. A PubMed, Cochrane Library, and EMBASE search from database inception through March 2024 was conducted. In this way, we compiled a total of thirty-five cases in our review. As far as we know, our work gathers the largest number of patients with this condition. Remarkably, we observed that the typical presentation of soft-tissue high-grade glioma metastases is the finding of subcutaneous erythematous nodules in patients previously operated on for a primary CNS tumor, within the craniotomy site and nearby, mostly in the first year after the initial surgery. It was also noted that there is a trend of developing a concomitant CNS recurrence and/or other metastases in different locations, either simultaneously or subsequently. From here, we propose some possible mechanisms that explain the extracranial spread of GBM. We concluded that a poor outcome is expected from the diagnosis of skin and subcutaneous metastases: the mean overall survival was 4.38 months. Yet, assessing individual characteristics is always mandatory; a palliative approach seems to be the best option for the majority of cases.

Efficacy of pitavastatin in patients with HIV: a systematic review and meta-analysis of randomized controlled trials

Abstract Background People with HIV (PWH) experience elevated cardiovascular disease (CVD) risk, exacerbated by antiretroviral therapy-induced dyslipidemia. Managing CVD risks in PWH presents significant challenges, notably due to the potential drug interactions. Pitavastatin is a statin with minimal interactions with antiretrovirals. Methods A systematic literature search of PubMed, Cochrane Library, and Embase databases was conducted up to March 1st, 2024, for studies comparing pitavastatin in PWH. Statistical software RStudio version 4.1.2 was used. Results Three studies with a total of 8045 participants were included in this analysis. Of these 4026 (50.04%) received pitavastatin. The mean age was 49.98 years and 69.38% were male. In the pooled analysis of studies, pitavastatin significantly reduced LDL cholesterol (MD -25.47; 95% CI -35.26 to -15.69; p<0.01; I² = 91%; Figure 1A) and non-HDL cholesterol (MD -27.53; 95% CI -41.19 to -13.87; p<0.01; I² = 91%; Figure 1B). Recently, the randomized trial to prevent vascular events in HIV study showed a reduction in adverse cardiovascular events and noncalcified plaque volume, as well as a reduction in inflammatory markers including oxidized LDL. Conclusions Pitavastatin offers a promising strategy for managing dyslipidemia and reducing CVD risk in PWH by reducing cholesterol, improving coronary plaque characteristics and inflammatory markers.

The Role of CLDN18.2 in Gastric Cancer Prognosis: A Systematic Review and Meta-Analysis

Background Gastric cancer (GC) is a major global cause of cancer mortality, with a median overall survival of just 12 months. CLDN18.2, a specific isoform of Claudin18 normally expressed in the gastric mucosa, has emerged as a potential therapeutic target and prognostic biomarker due to its exposure on the surface of tumor cells following malignant transformation. This exposure allows CLDN18.2's extracellular loops to bind monoclonal antibodies, presenting new opportunities for targeted therapy and improved prognostic assessment. Methods A comprehensive search of PubMed, EMBASE, Cochrane Library and Web of Science databases was conducted for studies that addressed the correlation of CLDN18.2 with: (1) Progression-free survival (PFS), and (2) Overall Survival (OS). Hazard ratio (HR) and odds ratio (OR) with 95% confidence intervals (CIs) were calculated using a fixed-effects model. Heterogeneity was examined with I2 statistics. P values of ≤ 0.05 were considered statistically significant. Statistical analyses were performed using RStudio, version 4.2.3. Results A total of 15 studies encompassing a total of 4,085 patients were included. There were 2,691 (65.8%) male, and 1,394 (34.2%) female patients. In the histologic GC analysis, there were 1,582 (38.7%) patients that had intestinal type and 1,280 (31.3%) with diffuse type. Patients with CLDN18.2 negative status exhibited a non-significant trend towards prolonged PFS (HR: 1.25; 95% CI: 0.98-1.61; p = 0.07; I2=18%) and a significant prolonged OS (HR: 1.20; 95% CI: 1.07-1.34; p < 0.01; I2=37%) when compared to CLDN18.2-positive patients. Conclusion Our findings establish CLDN18.2 as a robust negative prognostic indicator for overall survival in GC patients. While its impact on PFS was not statistically significant, the association with OS suggests CLDN18.2 may serve as a marker for complex biological processes underlying tumor advancement.

Effectiveness of combined physical exercise and cognitive training in older adults with cognitive impairment: A systematic review and meta-analysis

Falls among cognitively impaired older adults are a global concern. The aim of this study was to assess the efficacy of combining physical exercise and cognitive training to improve balance among older adults. A systematic search of databases, including Embase, Medline-OVID, CINAHL-EBSCOhost, and Central-Cochrane Library, was conducted from March 9 to April 6, 2023. The search used keywords based on the PICO question, where the population was older adults with cognitive impairment. Compared to a single therapy, the intervention involved a combination of muscle strengthening and cognitive therapy, with the outcome of falls or balance. Inclusion criteria were randomized controlled trials (RCTs) in any setting. Studies with participants under 60 years old and lacking baseline clinical assessments were excluded. EndNote 20 was used as a reference manager tool, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 flow diagram was used to map out the number of identified records. Two investigators worked independently, and the Jadad scale was used for critical appraisal. The PROSPERO registration number is CRD42023454876. A fixed-effects meta-analysis was performed using an inverse-variance method. Four articles met the inclusion criteria, three of which were included in the meta-analysis. Studies were from Europe, New Zealand, and the Philippines, with a total sample of 255 participants and mean ages of 65.9–87.5 years. The studies used combined physical and cognitive training in one group. Results showed a significant moderate effect size (effect size (ES): 2.29; standardized mean difference (SMD): 0.41; p&lt;0.05; heterogeneity (I2): 0%) indicating no heterogeneity. In conclusion, the combined intervention displayed the potential to improve balance for cognitively impaired older adults.

A Systematic Review of Renal Perfusion in Complex Abdominal Aortic Aneurysm Open Repair

Introduction: This systematic review aims to analyze the current literature regarding 30-day mortality and postoperative acute kidney disease (AKI) in complex abdominal aortic aneurysms (cAAAs), which included juxtarenal aortic aneurysm (JAA), suprarenal aortic aneurysm (SRAA), and type IV thoracoabdominal aortic aneurysm (TAAA) open surgery (OS), to evaluate the impact of renal perfusion on AKI and to try to define which is the best way to perform it. Methods: A literature search in PubMed and Cochrane Library was performed, and articles published from January 1986 to January 2024 reporting on JAA, SRAA, and TAAA type IV open surgery management were identified. Multicenter studies, single-center series, and case series with ≥10 patients were considered eligible. Comparisons of outcomes of patients who underwent OS for complex abdominal aortic aneurysms (cAAAs) with or without perfusion of the renal arteries were analyzed when available. The titles, abstracts, and full texts were evaluated by two authors independently. The primary outcomes included AKI and 30-day mortality rates. The new-onset dialysis rate was considered a secondary outcome. Results: A total of 295 articles were evaluated, and 21 were included, totaling 5708 patients treated for cAAAs with OS. The male patients totaled 4094 (71.7%), with a mean age of 70.35 ± 8.01 and a mean renal ischemia time of 32.14 ± 12.89 min. Data were collected and analyzed, at first in the entire cohort and then divided into two groups (no perfusion of the renal arteries—group A vs. selective perfusion—group B), with 2516 patients (44.08%) who underwent cAAAs OS without perfusion of the renal arteries and 3192 patients (55.92%) with perfusion. In group B, four types of renal perfusion were reported. Among the 21 studies included, 10 reported on selective renal perfusion in cAAA OS, with several types of fluids described: (1) “enriched” Ringer’s solution, (2) “Custodiol” (Istidine-tryptophan-ketoglutarate or Custodiol HTKsolution), (3) other cold (4 °C) solutions (i.e., several combinations of 4 °C isotonic heparinized balanced salt solution containing mannitol, sodium bicarbonate, and methylprednisolone), and (4) warm blood. Thirty-day mortality for patients in group A was 4.25% (107/2516) vs. 4.29% (137/3192) in group B. The reported incidence of AKI and new onset of dialysis was, respectively, 22.14% (557/2516) and 5.45% (137/2516) for group A and 22.49% (718/3192) and 4.32% (138/3192) for group B. A total of 579 patients presented with chronic kidney disease (CKD) at admission across all studies, which included 350 (13.91%) in group A vs. 229 (7.17%) in group B. Acute kidney injury, 30-day mortality, and new-onset dialysis rate were reported in four subgroups: (1) In the “Ringer” group, 30-day mortality was 2.52% (3/113), AKI affected 27.73% (33/119) of patients, and the new-onset dialysis rate was 2.52% (3/113). (2) In the “Custodiol” group, 30-day mortality was 3.70% (3/81), AKI affected 20.17% (24/81) of patients, and the new-onset dialysis rate was 2.46% (2/81). (3) In the “cold solutions” group (i.e., NaCl and mannitol), 30-day mortality was 4.38% (130/2966), AKI affected 21.81% (647/2966) of patients, and the new-onset dialysis rate was 4.48% (133/2966). (4) In the “Warm blood” group, 30-day mortality was 3.85% (1/26), AKI affected 53.84% (14/26) of patients, and the new-onset dialysis rate was 0% (0/26). Conclusions: This systematic review highlights the lack of standard definitions for AKI, CKD, and the type of renal perfusion. Despite similar results in terms of AKI and 30-day mortality, renal perfusion seems to be protective of the new-onset hemodialysis rate. Moreover, Custodiol appears to have lower rates of AKI and hemodialysis than the other perfusion types. A prospective randomized controlled trial to perform further subgroup analysis and research the various types of renal perfusion may be necessary to identify possible benefits.

Robotic colorectal surgery in Latin America: a systematic review on surgical outcomes

Background and objectivesRobotic approach in colorectal surgery is rapidly gaining interest, particularly in the context of rectal cancer resection. Despite economic barriers, substantial proliferation of robotic colorectal procedures has been observed throughout Latin America. However, there is a lack of data regarding intraoperative and early postoperative outcomes, as well as oncological and long-term results. This systematic review aims to provide an overview of the surgical outcomes of robotic-assisted colorectal approaches across Latin America.Material and methodsA systematic literature search of electronic databases, including PubMed, LILACS, Scopus, Cochrane Library and Scielo, was performed and reported in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The main target of the literature search was studies that reported outcomes of colorectal robotic surgery in Latin America.ResultsA total of 9,694 published articles were identified from the initial search. Nine thousand six hundred thirty-six publications were excluded after title and abstract review and removal of duplicates. Fifty-eight articles were thoroughly reviewed, and 11 studies met the inclusion criteria. The critical appraisal of study quality (biases risk assessment) was performed according to the Joanna Briggs Institute (JBI) Manual for Evidence Synthesis. In general, the overall study quality was poor. Of the 11 studies included in the analysis, ten addressed intraoperative and early postoperative outcomes, seven addressed oncological/pathological outcomes, and just one addressed long-term outcomes. Ten studies evaluated intraoperative and early postoperative outcomes, encompassing a total of 425 patients, the majority of whom were diagnosed with colorectal cancer. Morbidity rates exhibited a range between 0% and 45.9%, while mortality ranged from 0% to 2.5%.ConclusionFew studies have been published addressing intraoperative, postoperative, pathological, and oncological outcomes of robotic colorectal surgery in this region. Undoubtedly, there are unique challenges not encountered by developed countries, including economic obstacles in establishing structured training programmes and high-quality centres for the development of robotic surgery. Further studies are needed to assess the real extent of robotic surgery in the region and its results.Systematic Review Registrationhttps://www.crd.york.ac.uk/, PROSPERO (CRD42023494112).

Efficacy and safety of very early rehabilitation for acute ischemic stroke: a systematic review and meta-analysis

BackgroundEarly rehabilitation after acute ischemic stroke (AIS) contributes to functional recovery. However, the optimal time for starting rehabilitation remains a topic of ongoing investigation. This article aims to shed light on the safety and efficacy of very early rehabilitation (VER) initiated within 48 h of stroke onset.MethodsA systematic search in PubMed, Embase, Cochrane Library, and Web of Science databases was conducted from inception to January 20, 2024. Relevant literature on VER in patients with AIS was reviewed and the data related to favorable and adverse clinical outcomes were collected for meta-analysis. Subgroup analysis was conducted at different time points, namely at discharge and at three and 12 months. Statistical analyses were performed with the help of the Meta Package in STATA Version 15.0.ResultsA total of 14 randomized controlled trial (RCT) studies and 3,039 participants were included in the analysis. VER demonstrated a significant association with mortality [risk ratio (RR) = 1.27, 95% confidence interval (CI) (1.00, 1.61)], ability of daily living [weighted mean difference (WMD) = 6.90, 95% CI (0.22, 13.57)], and limb motor function [WMD = 5.02, 95% CI (1.63, 8.40)]. However, no significant difference was observed between the VER group and the control group in adverse events [RR = 0.89, 95% CI (0.79, 1.01)], severity of stroke [WMD = 0.52, 95% CI (−0.04, 1.08)], degree of disability [RR = 1.06, 95% CI (0.93, 1.20)], or recovery of walking [RR = 0.98, 95% CI (0.94, 1.03)] after stroke. Subgroup analysis revealed that VER reduced the risk of adverse events in the late stage (at three and 12 months) [RR = 0.86, 95% CI (0.74, 0.99)] and degree of disability at 12 months [RR = 1.28, 95% CI (1.03, 1.60)], and improved daily living ability at 3 months [WMD = 4.26, 95% CI (0.17, 8.35)], while increasing severity of stroke during hospitalization [WMD = 0.81, 95% CI (0.01, 1.61)].ConclusionVER improves activities of daily living (ADLs) and lowers the incidence of long-term complications in stroke survivors. However, premature or overly intense rehabilitation may increase mortality in patients with AIS during the acute phase.

Safety and efficacy of sertraline in depression among adults undergoing dialysis: A systematic review and meta-analysis

Background: Depression is prevalent among patients with end-stage renal disease (ESRD) undergoing dialysis, with significant implications for their quality of life and treatment compliance. Traditional treatments for depression, including various therapies and pharmacological interventions, have limitations due to their adverse effects. Sertraline, a selective serotonin re-uptake inhibitor (SSRI), offers a promising alternative, but its efficacy and safety in this population require thorough evaluation. Objective: This meta-analysis aims to assess the effectiveness and adverse effects of sertraline in treating depressive episodes in dialysis patients compared to placebo. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a comprehensive search of databases, including PubMed, Cochrane Library, and Science Direct, up to June 20, 2024. We included randomized controlled trials (RCTs) that compared sertraline with placebo in dialysis patients with depression. Two researchers independently performed data extraction and risk of bias assessment. Statistical analysis was conducted using ReviewManager 5.4.1, employing a random effects model. Results: Four RCTs involving 468 participants were included. Sertraline significantly reduced depressive symptoms, as measured by the Quick Inventory of Depressive Symptomatology (QIDS) and Beck Depression Inventory-II (BDI-II) scores, at 6 and 12 weeks compared to placebo. Improvements in kidney disease-specific quality of life (KDQOL-36) scores were also noted. However, sertraline was associated with a higher risk of adverse events compared to placebo. Conclusions: Sertraline effectively reduces depressive symptoms and improves the quality of life in dialysis patients with ESRD. Despite the increased risk of adverse events, the overall benefits make sertraline a viable treatment option for this population. Larger, more comprehensive studies are needed to confirm these findings and optimize sertraline use in clinical practice.

Impact of cannabis abuse on the occurrence of stroke in young people: a systematic review and meta-analysis

BackgroundThe occurrence of stroke in young people has risen significantly. This can easily lead to physical disabilities, swallowing difficulties, and cognitive impairment, among other issues, having a profound impact on families and society. Risk factors for stroke in young people differ from those for traditional stroke, with cannabis abuse emerging as a significant high-risk factor. However, the extent of the impact of cannabis abuse on the occurrence of stroke and the rate of disability in young people remains unclear. To clarify this issue and provide evidence supporting the primary prevention of stroke in young people, this systematic review and meta-analysis summarizes the latest findings from previous studies.MethodsA systematic search of PubMed, EMBASE, Cochrane Library, and Web of Science databases was conducted until April 2023. The review included observational studies comparing stroke risk estimates between cannabis abusers and non-users.ResultsThis review included six observational studies focusing on cannabis abuse, involving 119,284,152 participants. A significant association was found between cannabis abuse and an increased risk of stroke [OR = 1.14, 95% CI (1.08, 1.20)]. However, there was substantial heterogeneity among the studies (I2 = 89%, p &amp;lt; 0.001). After adjusting for confounders such as smoking and alcohol abuse, we found a stronger association between cannabis abuse and stroke in young adults [OR = 1.21, 95% CI (1.12, 1.29)]. Subgroup analyses revealed no significant difference in stroke risk between ischemic and hemorrhagic strokes (p = 0.43).ConclusionThe results of our systematic review and meta-analysis showed that cannabis abuse has a more significant effect on the occurrence of stroke in young people; however, it was not possible to distinguish whether cannabis abuse is more likely to cause ischemic or hemorrhagic stroke. Further research is needed to explore the impact of different drug types, dosages, and behaviors on stroke risk.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/, Identifier CRD42023443261.

Identification of Motives of Children Working as Street Clowns in Manado City, North Sulawesi Province

Various activities are carried out by the community to meet their living needs. One activity that has become a new phenomenon seen in Manado City is street clowns. The phenomenon of street clowns can be found at intersections and at the entrances and exits of the Boulevard shopping area. They try to entertain the general public and drivers so that they get money, although the amount is not much. However, most of these street clowns are of school age and should not be active to earn income. This phenomenon is actually different from the culture of the Manado City Community in carrying out activities to earn income. This study was conducted to identify and analyze the motives of children who work as street clowns in Manado City. The results of this study can be used as a recommendation for the Manado City government in compiling a program to strengthen social institutions in the Community and in maintaining public order in public places. This study will be conducted using a qualitative method with a phenomenological approach. Data were collected through interviews with children who work as street clowns and with the leaders of the Social and Community Empowerment Service and the leaders of the Manado City Civil Service Police Unit. Conducting observations on the activities of street clown professions and collecting other supporting data through internet-based electronic library searches such as Google Scholar and ResearchGate. Data analysis through the stages of data reduction, data presentation and drawing conclusions and data verification. Children who work as street clowns in Manado City are school-age children. The main motive is to help parents meet their living needs through additional income. They come from suburban areas and have a community. The hope of feeling affection and attention and having time to play is very much needed by them.

Targeted and Untargeted Amine Metabolite Quantitation in Single Cells with Isobaric Multiplexing.

We developed a single cell amine analysis approach utilizing isobarically multiplexed samples of 6 individual cells along with analyte abundant carrier. This methodology was applied for absolute quantitation of amino acids and untargeted relative quantitation of amines in a total of 108 individual cells using nanoflow LC with high-resolution mass spectrometry. Together with individually determined cell sizes, this provides quantification of intracellularconcentrations within individual cells. The targeted method was partially validated for 10 amino acids with limits of detection in low attomoles, linear calibration range covering analyte amounts typically from 30 amol to 120 fmol, and correlation coefficients (R) above 0.99. This was applied with cell sizes recorded during dispensing to determine millimolar intracellular amino acid concentrations. The untargeted approach yielded 249 features that were detected in at least 25% of the single cells, providing modest cell type separation on principal component analysis. Using Greedy forward selection with regularized least squares, a sub-selection of 100 features explaining most of the difference was determined. These features were annotated using MS2 from analyte standards and accurate mass with library search. The approach provides accessible, sensitive, and high-throughput method with the potential to be expanded also to other forms of ultrasensitive analysis.

Costs of Illness for Huntington's Disease: A Systematic Review.

Huntington's disease (HD) is associated with significant financial burden for patients and payers. The objective was to identify and quantify costs of HD by stage of disease progression. A systematic search of Medline, Embase, Scopus, and Cochrane Library was used to identify types of costs that are frequently reported for individuals diagnosed with HD and to quantify those costs across early, middle, and late stages of HD. Full-text, original research articles were included if they reported costs specific to HD burden. To standardize stage-level costs, Shoulson Fahn and Barthel Index scores were combined to estimate the cost for early, middle-, and late-stage HD. A total of 692 abstracts were identifie,d and following abstract screening, a total of 80 full-text articles were reviewed for inclusion. Only five studies were included for extraction and synthesis including three from the USA, one from the United Kingdom (UK), and one from Peru. Annual inpatient, outpatient, drug costs, and caregiving costs all increased substantially as disease progressed. Outpatient costs were approximately 2.5 times greater than inpatient costs for early and middle stages of HD. Among all the costs associated with HD, annual caregiver cost emerges as the most significant costs in the economic burden of HD, ranging from a minimum of $6041 for early stage to a maximum of $133,200 for late-stage HD. Significant variation was observed across studies, especially comparing costs observed in Peru with the USA and UK. Outpatient costs exceed inpatient costs, especially in early and middle stages, underscoring the importance of outpatient care. All costs seem to rise rapidly, in a nonlinear fashion, as patients advance to later stages. While only two studies reported caregiver burden, these costs were significanly higher in the most severe stage, where patients were completely dependent on a caregiver. This review highlights the complexity of cost assessment in HD and underscores the need for consistent methods and further research to guide effective policy actions.

Pemetrexed and platinum with or without pembrolizumab for advanced non-small-cell lung cancer (NSCLC): a systematic review and meta-analysis.

This meta-analysis aimed to evaluate the efficacy and safety of combining pemetrexed and platinum with or without pembrolizumab for the treatment of advanced non-small-cell lung cancer (NSCLC). A systematic search of PubMed, Embase, Cochrane Library, and Web Of Science databases was conducted to identify studies comparing pemetrexed and platinum with or without pembrolizumab in advanced NSCLC. Raw data were extracted from eligible studies to calculate Hazard Ratios (HR) for Progression-Free Survival (PFS) and Overall Survival (OS), as well as rates of adverse events of all grades and those of Grade 3 or higher. Eight studies with 1639 patients occurred advanced NSCLC included. The group receiving pembrolizumab in combination with pemetrexed and platinum showed significant benefits in terms of OS (HR 0.63; 95% CI 0.54-0.73; p < 0.00001) and PFS (HR:0.64; 95% CI 0.48-0.85; p = 0.002) compared to the group receiving pemetrexed and platinum alone. However, this benefit was accompanied by a higher incidence of Grade 3 or higher adverse events (OR: 1.55; 95% CI 1.24-1.95; p = 0.0001). The combination of pemetrexed and platinum with pembrolizumab is recommended as a first-line treatment option for advanced NSCLC due to its significant efficacy benefits. However, the increased risk of Grade 3 or higher adverse events suggests the need for careful consideration and assessment when considering this regimen for second-line or subsequent therapy.

Temporal Evolution of Bradford Curves in Academic Library Contexts

Bradford’s law of bibliographic scattering is a fundamental principle in bibliometrics, offering valuable guidance for academic libraries in literature search and procurement. However, Bradford curves can exhibit various shapes over time, and predicting these shapes remains a challenge due to a lack of causal explanation. This paper attributes the deviations from the theoretical J-shape to integer constraints on the number of journals and articles, extending Leimkuhler’s function to encompass highly productive core journals, where the theoretical journal number falls below one. Using the Simon–Yule model, key parameters of the extended formulas are identified and analyzed. The paper explains the reasons for the Groos droop and examines the critical points for shape changes. The proposed formulas are validated with empirical data from the literature, demonstrating that this method can effectively predict the evolution of Bradford curves, providing academic libraries with a valuable tool for evaluating journal coverage, optimizing resource allocation, and refining Collection Development Policies (CDP).

Efficacy of Chronic Use of Sodium-Glucose Co-transporter 2 Inhibitors on the Prevention of Contrast-Induced Acute Kidney Injury in Patients with Type 2 Diabetes Mellitus Following Coronary Procedures: A Systematic Review and Meta-Analysis.

Contrast-induced acute kidney injury (CI-AKI) is a common complication of iodinated contrast administration during coronary procedures, especially in patients with diabetes mellitus (DM). Besides periprocedural hydration and statins, there are no other pharmacological strategies with consistent results to prevent CI-AKI up to date. This study aims to evaluate the efficacy of chronic use of sodium-glucose co-transporter 2 (SGLT2) inhibitors on the prevention of CI-AKI in patients with type 2 DM following coronary procedures. A systematic literature search of MEDLINE, Google Scholar, Embase, and Cochrane Library was performed. Relevant observational studies and randomized controlled studies (RCTs) were identified. Results were pooled using a random-effect model meta-analysis. Subgroup analyses were performed to evaluate the potential benefit of SGLT2 inhibitors on the prevention of CI-AKI in patients undergoing urgent or elective coronary angiography/percutaneous coronary interventions (CAG/PCI). Seven observational studies and one randomized controlled trial with 2740 patients were included. Chronic treatment (minimum duration 2 weeks to 6 months) with an SGLT2 inhibitor was associated with a significantly reduced risk of CI-AKI in diabetic patients undergoing coronary procedures compared with the control group [risk ratio (RR) 0.48; 95% confidence interval (CI) 0.39-0.59; p < 0.001). Results of subsequent subgroup analysis showed a significant reduction in the incidence of CI-AKI in diabetic patients undergoing both elective CAG/PCI (RR 0.49; 95% CI 0.35-0.68; p<0.001) and urgent CAG/PCI (RR 0.48; 95% Cl 0.35-0.66; p < 0.001). Chronic use of SGLT2 inhibitors may be preventative against the incidence of CI-AKI in patients with type 2 DM undergoing coronary interventions. Further RCTs are needed to confirm our findings.

FACTORS THAT CONTRIBUTE TO REPORT WRITING PROFICIENCY IN AMERICAN LAW ENFORCEMENT: A THEMATIC LITERATURE REVIEW

Purpose: This thematic literature review explores the critical role of competent writing skills in law enforcement, examining its impact on career progression, agency reputation, and legal proceedings. The purpose is to synthesize existing literature to identify research gaps and suggest directions for future studies. Methods: Google Scholar, ERIC, and the Jerry Falwell Library searches were conducted to capture a broad range of studies involving police report writing, its impact on officers, law enforcement agencies, and the criminal justice system, and writing improvement strategies. Although not required for this review, the work followed PRISMA-ScR guidelines. Results: The initial search yielded numerous qualitative and quantitative studies. This review categorizes the findings into themes of the importance of writing proficiency, the influence of organizational culture, training and education, and technological integration, highlighting the variability and scope of the existing literature. Conclusions: The review shows the need for well-structured research to substantiate the factors contributing to effective law enforcement report writing. It recommends areas for in-depth exploration in future systematic reviews or primary studies, especially longitudinal studies on the effects of targeted training programs, organizational culture shifts, and technological integration on writing proficiency. Application in Law Enforcement: For trainers and instructors, integrating comprehensive report writing programs into training for law enforcement officers can enhance professional skills and accountability. Effective report writing improves documentation accuracy, supports legal proceedings, and enhances career progression. Incorporating targeted report writing training can holistically enhance the performance and professionalism of law enforcement officers.
